         At the URS  Meeting,  you  will be asked to  consider  and vote  upon a
proposal to approve  the  Agreement  and Plan of Merger,  dated as of August 18,
1997 (the  "Merger  Agreement"),  among URS and  Woodward-Clyde  Group,  Inc., a
Delaware  corporation ("WC"). The Merger Agreement provides for the merger of WC
with and into a wholly-owned  subsidiary of URS (the  "Merger").  As a result of
the Merger,  the  stockholders  of WC will exchange their WC stock for aggregate
consideration  of $100 million,  consisting of $35 million in cash and shares of
URS  Common  Stock  with a value  at the  closing  of $65  million  (subject  to
adjustment  in  certain  circumstances  as noted in the  Prospectus/Joint  Proxy
Statement accompanying this letter).

         After careful  consideration,  your Board of Directors has  unanimously
approved the Merger  Agreement  and the  transactions  it  contemplates  and has
concluded that they are in the best interests of URS and its stockholders.  Your
Board of Directors  unanimously  recommends that the stockholders of URS approve
the Merger.

         In the material  accompanying  this  letter,  you will find a Notice of
Special Meeting of Stockholders,  a Prospectus/Joint Proxy Statement relating to
the actions to be taken by URS  stockholders  at the URS Meeting (as well as the
actions  to be taken by the WC  stockholders  at their  special  meeting)  and a
proxy.  The  Prospectus/Joint  Proxy Statement more fully describes the proposed
Merger and includes information about URS and WC.

         All URS stockholders are cordially invited to attend the URS Meeting in
person.  However,  whether  or not you plan to attend  the URS  Meeting,  please
complete,  sign,  date and return your proxy in the  enclosed  envelope.  If you

         We hope you can join us on November 13.

                         shares  of URS  Common  Stock for the  approval  of the
                         Merger  Agreement at the URS  Meeting.  Delivery of the
                         proxy solicited  hereby or attendance and voting at the
                         URS Meeting will revoke and supersede any prior proxy.

                 Recommendation of the Board of Directors of URS

Approval by the Board    The Board of Directors of URS has unanimously  approved
                         the Merger Agreement and has determined that the Merger
                         is in the best  interests of URS and its  stockholders.
                         THE  URS  BOARD  OF  DIRECTORS  UNANIMOUSLY  RECOMMENDS
                         APPROVAL  AND  ADOPTION OF THE MERGER  AGREEMENT BY THE
                         URS  STOCKHOLDERS.  The primary factors  considered and
                         relied upon by the URS Board of  Directors  in reaching
                         its  recommendation  are  described  in  "The  Merger--
                         Reasons for the Merger."

Opinion of URS
Financial  Advisor       Smith  Barney  Inc.   ("Smith  Barney")  has  acted  as
                         financial  advisor to URS in connection with the Merger
                         and has  delivered  to the Board of  Directors of URS a
                         written  opinion  dated  August 18,  1997 to the effect
                         that, as of the date of such opinion and based upon and
                         subject to certain matters stated  therein,  the Merger
                         Consideration  (as  defined  below)  was  fair,  from a
                         financial  point of view,  to URS. The full text of the
                         written  opinion of Smith Barney dated August 18, 1997,
                         which  sets  forth  the   assumptions   made,   matters
                         considered and limitations on the review undertaken, is
                         attached as Appendix B to this Prospectus and should be
                         read  carefully in its  entirety.  The opinion of Smith
                         Barney is directed to the Board of Directors of URS and
                         relates   only   to  the   fairness   of   the   Merger

                         does not  address  any other  aspect  of the  Merger or
                         related   transactions   and  does  not   constitute  a
                         recommendation  to  any  stockholder  as  to  how  such
                         stockholder should vote at the URS Special Meeting. See
                         "The Merger-- URS Financial Advisor."

                         outstanding on the WC Record Date, voting as a separate
                         class.  Approval  of the  Merger  Agreement  also  will
                         require  the  affirmative  vote  of a  majority  of the
                         shares  of WC  Preferred  Stock  outstanding  on the WC
                         Record Date,  voting as a separate  class.  All of WC's

                 Recommendation of the Board of Directors of WC

Approval by the Board    The Board of Directors of WC has  unanimously  approved
                         the Merger Agreement and the Merger and determined that
                         the  Merger  is in the  best  interests  of WC and  its
                         stockholders.   THE  WC   BOARD   RECOMMENDS   THAT  WC
                         STOCKHOLDERS  VOTE  FOR  THE  APPROVAL  OF  THE  MERGER
                         AGREEMENT AND AMENDMENT OF THE SHAREHOLDERS' AGREEMENT.
                         For a discussion  of the factors  considered  by the WC
                         Board in  reaching  its  decision,  see  "The  Merger -
                         Reasons for the Merger; Recommendations of the Board of
                         Directors of WC."

Opinion of WC
Financial Advisor        Oppenheimer  & Co., Inc.  ("Oppenheimer")  has acted as
                         financial  advisor to WC in connection  with the Merger
                         and has  delivered  to the Board of  Directors  of WC a
                         written opinion that the  consideration  to be received
                         by  the  current   holders  of  WC  Capital   Stock  in
                         connection with the Merger is fair to such holders from
                         a financial point of view. The full text of the opinion
                         of Oppenheimer,  which sets forth the assumptions made,
                         matters   considered  and  limitations  on  the  review
                         undertaken by Oppenheimer, is attached as Appendix C to
                         this Prospectus.  WC stockholders are urged to read the
                         opinion in its entirety.  The opinion of Oppenheimer is
                         directed  to the Board of  Directors  of WC and relates
                         only to the fairness of the Merger Consideration from a
                         financial  point of view to the  current  holders of WC
                         Common Stock,  does not address any other aspect of the
                         Merger or related  transactions and does not constitute
                         a  recommendation  to WC  stockholders  as to how  such
                         stockholders  should vote with  respect to whether they
                         should  approve  the  Merger.  See  "The  Merger  -  WC
                         Financial Advisor."

                                   The Merger

General Terms            On August  18,  1997,  URS,  WC and  Acquisition  Corp.
                         entered into the Merger Agreement, which sets forth the
                         terms  and  conditions  of the  Merger.  A copy  of the
                         Merger  Agreement  is  included in this  Prospectus  as
                         Appendix  A. The Merger  will be  consummated  promptly
                         after  the  necessary  approvals  of  the  URS  and  WC
                         stockholders   have   been   obtained   and  the  other
                         conditions  to  consummation  of the  Merger  have been
                         satisfied  or  waived  (the   "Effective  Time  of  the
                         Merger").  Upon  consummation  of the  Merger,  WC will
                         merge with and into Acquisition Corp. As a result,  the
                         stockholders of WC will become  stockholders of URS (as
                         described below),  and their rights will be governed by
                         URS's Amended and Restated Certificate of Incorporation
                         and Bylaws. See "The Merger."

                         By  virtue  of the  Merger,  each of the  shares  of WC
                         Capital Stock issued and outstanding  immediately prior
                         to the  Effective  Time of the Merger  (see "The Merger
                         Effective Time of the Merger") will automatically be

                         converted  into and exchanged for the right to receive,
                         in the aggregate,  the Merger  Consideration.  See "The
                         Merger."

Merger Consideration     As a result  of the  Merger,  the  shares  of WC Common
                         Stock will be converted  into the right to receive,  in
                         the aggregate,  $91,693,870,  consisting of $26,693,870
                         in cash and shares of URS Common  Stock with a value at
                         the  Effective  Time  of the  Merger  of  $65  million,
                         subject  to  adjustment  in  certain  circumstances  as
                         described below. The value of the URS Common Stock will
                         be determined on the basis of the average daily closing
                         price for such  stock on the NYSE  over the 20  trading
                         days  preceding  the  closing of the  Merger  (the "URS
                         Closing  Price").  However,  in no event will the total
                         number of shares  of URS  Common  Stock to be issued to
                         the  holders  of WC  Common  Stock as a  result  of the
                         Merger  exceed   5,200,000   shares  or  be  less  than
                         4,044,804 shares. Consequently, even if the URS Closing
                         Price is greater than $16.07 (the price  resulting from
                         dividing $65 million by the minimum number of shares of
                         URS Common Stock),  the holders of WC Common Stock will
                         receive,  in the  aggregate,  the minimum of  4,044,804
                         shares of URS  Common  Stock  (which  will have a value
                         greater  than $65 million) and also will be entitled to
                         receive the $26,693,870 in cash. Conversely, if the URS
                         Closing Price is less than $12.50 (the price  resulting
                         from  dividing  $65  million by the  maximum  number of
                         shares of URS Common  Stock),  the holders of WC Common
                         Stock will receive,  in the  aggregate,  the maximum of
                         5,200,000 shares of URS Common Stock (which will have a
                         value  less than $65  million),  but in this  event the
                         cash component of the  consideration  will be increased
                         so  that  the sum of the  value  of the  shares  of URS
                         Common Stock and the cash to be received by the holders
                         of the WC Common Stock will still equal $91,693,870.

                         The  aggregate  consideration  to be  received  by  the
                         holders  of the WC  Common  Stock  as a  result  of the
                         Merger will be  allocated  among such  holders pro rata
                         based on the  number of shares of WC Common  Stock held
                         so that the aggregate  consideration  to be received in
                         exchange  for each  share of WC  Common  Stock  will be
                         equal.  Based on  1,964,175  shares of WC Common  Stock
                         issued  and  outstanding  on the WC  Record  Date,  and
                         assuming that the URS Closing Price is $14.28 per share
                         (the average  daily closing price for such stock on the
                         NYSE over the 20 trading  days  preceding  the date the
                         Merger  Agreement was signed),  each share of WC Common
                         Stock  would be  converted  into the  right to  receive
                         $13.59 in cash and 2.317  shares of URS  Common  Stock,
                         which would have an indicated aggregate value of $46.68
                         per share of WC Common Stock.

                         The shares of WC Preferred Stock, all of which are held
                         by the General Trustee of the WC Retirement  Plan, will
                         be converted  into the right to receive  $8,306,130  in
                         the  aggregate  in cash.  Payment will be made upon the
                         surrender of the certificate(s)  formerly  representing
                         such shares of WC Preferred Stock.

                         The  consideration  for the WC Common  Stock and the WC
                         Preferred  Stock is  collectively  referred  to in this
                         Prospectus as the "Merger  Consideration".  No interest
                         will  accrue or be  payable  with  respect  to the cash
                         portion of the Merger Consideration.  See "The Merger -
                         Merger Consideration."

Fractional Shares        No fractional shares of URS Common Stock will be issued
                         in  connection  with  the  Merger.   Fractional  shares
                         otherwise  issuable  will be settled for cash,  without
                         interest,  based on the closing  price per share of URS
                         Common Stock as quoted in The Wall Street  Journal (the
                         "WSJ") on the trading  day  immediately  preceding  the
                         Closing Date (as defined in the Merger Agreement,  this
                         is the date on which all  conditions to the Merger have
                         been  satisfied,  which is expected  to be  immediately
                         prior or contemporaneous with the Effective Time of the
                         Merger).

Issuance and Exchange
of Share Certificates    At the Effective Time of the Merger,  each holder of WC
                         Capital Stock prior to  consummation of the Merger will
                         be  entitled,   upon   surrender  of  the   certificate
                         representing  such shares or compliance with procedures
                         for  transfer  of shares  held in book entry  form,  to
                         receive  such  holder's  allocable  share of the Merger
                         Consideration described above. The Merger Consideration
                         allocable  to each holder will not be  delivered  until
                         such holder's certificates  evidencing WC Capital Stock
                         have  been  surrendered  by  the  holder  or his or her
                         nominee. WC stockholders will be furnished separately a
                         Letter of  Transmittal to facilitate the delivery of WC
                         Capital Stock certificates or shares held in book entry
                         form to the Exchange  Agent  designated to disburse the
                         Merger Consideration.  PLEASE DO NOT DELIVER YOUR STOCK
                         CERTIFICATES  TO WC OR THE  EXCHANGE  AGENT  UNTIL  YOU
                         RECEIVE THE LETTER OF TRANSMITTAL AND INSTRUCTIONS FROM
                         THE EXCHANGE  AGENT.  See "The Merger - Conversion  and
                         Exchange of WC Capital Stock Certificates."

Marketability of
URS Common Stock         The  shares  of URS  Common  Stock to be  issued to the
                         holders  of WC Common  Stock as a result of the  Merger
                         will have been  registered  under the Securities Act of
                         1933, as amended (the "Securities Act"), will be listed
                         on the New York Stock Exchange ("NYSE") and the Pacific
                         Exchange ("PE") and will be freely marketable. However,
                         any  holder of WC  Common  Stock who is deemed to be an
                         affiliate of WC at the Effective Time of the Merger and
                         any such  person who becomes an  affiliate  of URS as a
                         result of or  following  the Merger  will be subject to
                         the volume and manner of sale  restrictions  imposed on
                         resales  of the URS  Common  Stock by Rules 144 and 145
                         under the Securities Act. See "Affiliates' Restrictions
                         on  Sale  of  URS  Common   Stock."  In  addition,   in
                         connection with the Merger, each officer,  director and
                         holder of one percent  (1%) or more of the  outstanding
                         shares of WC Common  Stock  will be asked to  provide a
                         continuity  of  interest  representation  in  a  manner
                         sufficient to satisfy the  requirements of the Internal
                         Revenue Code for  treatment of the Merger as a tax-free
                         reorganization.  See  "The  Merger  -  Certain  Federal
                         Income Tax Matters."

Comparison of Rights of
Stockholders of URS
and WC                   The rights of WC's stockholders are currently  governed
                         by   Delaware   law   and  by   WC's   Certificate   of
                         Incorporation and Bylaws. Upon the effectiveness of the
                         Merger,  WC's stockholders will become  stockholders of
                         URS and their rights as URS stockholders  will continue
                         to be governed by Delaware law and by URS's Amended and
                         Restated  Certificate of Incorporation and Bylaws.  See
                         "Comparison of Rights of Stockholders of URS and WC."

   
Conditions to Merger     The  obligations of URS and WC to consummate the Merger
                         are  subject to the  satisfaction  or waiver of certain
                         conditions   set   forth  in  the   Merger   Agreement,
                         including:  (i) the conditions to the receipt by URS of
                         funds from its  lenders to finance the Merger have been
                         satisfied, (ii) the registration of URS Common Stock to
                         be issued in the Merger  under the  Securities  Act has
                         remained  effective,  (iii) the  listings of URS Common
                         Stock to be issued in the Merger  with the NYSE and the
                         PE have  become  effective,  (iv)  the  Merger  and the
                         amendment  to the  Shareholders'  Agreement  have  been
                         approved  by  the   requisite   votes  of  WC  and  URS
                         stockholders,  (v) there has been no  material  adverse
                         change affecting WC or URS, (vi) there is no litigation
                         challenging  the  Merger,  and  (vii)  each  party  has
                         received  customary legal opinions,  including opinions
                         of  counsel  to  the  effect   that  the  Merger   will
                         constitute  a  reorganization  within  the  meaning  of
                         Section 368 of the Internal  Revenue  Code of 1986,  as
                         amended  (the  "Code").  The waiting  period  under the
                         Hart-Scott-Rodino Antitrust Improvement Act of 1976, as
                         amended  ("HSR Act"),  was  terminated  on September 8,
                         1997. See "The Merger - The Merger Agreement."
    

Financing Facilities     URS has received a  commitment  letter from Wells Fargo
                         Bank,  National  Association  with  respect to term and
                         revolving  credit  facilities  which will  provide  the
                         funds  necessary  for the cash  portion  of the  Merger
                         Consideration,    for   refinancing   existing   credit
                         facilities  and  for  working  capital   following  the
                         Merger. The obligation of URS's lenders to provide such
                         funds  is  subject  to  satisfaction  of  a  number  of
                         conditions  precedent by each of URS and WC,  including
                         that URS and WC meet specified  financial  tests,  that
                         there  have been no  material  adverse  changes  in the
                         respective  businesses  of URS and WC,  that final loan
                         documents have been executed and delivered and that all
                         conditions precedent to the Merger have been satisfied.
                         See "The Merger - Financing of the Merger."

Termination, Waiver
and  Amendment           The  Merger  Agreement  may be  terminated  at any time
                         prior  to the  Effective  Time  of the  Merger:  (a) by
                         mutual written consent of URS and WC; or (b) in certain
                         circumstances by either WC or URS if (i) there has been
                         an uncured  breach by the other  party of any  material
                         representation,  warranty,  covenant or other agreement
                         in the Merger Agreement; (ii) any of the conditions set
                         forth in the Merger  Agreement  have not been fulfilled
                         on or prior to the date  specified for  fulfillment  or
                         have become impossible to fulfill,  or (iii) the Merger
                         has not been consummated by December 31, 1997. See "The
                         Merger - The Merger Agreement."

                         At any time before the Merger  becomes  effective,  any
                         party to the Merger  Agreement  may (i) extend the time
                         for the  performance of any of the obligations or other
                         acts of the other parties to the Merger Agreement, (ii)
                         waive  any  inaccuracies  in  the  representations  and
                         warranties contained in the Merger Agreement, and (iii)
                         waive compliance with any of the agreements,  covenants
                         or conditions  for the benefit of such party  contained
                         in the Merger Agreement. However, the Commitment Letter
                         provides  that  URS  may  not  agree  to  any  material
                         amendment  to,  or  waive  any of its  material  rights
                         under, the Merger  Agreement  without the prior written
                         consent of Wells Fargo.

                         The terms of the  Merger  Agreement  would  permit  the
                         waiver  of  the  condition  that  the  parties  receive
                         opinions  from  counsel to the  effect  that the Merger
                         will constitute a  "reorganization"  within the meaning
                         of Section 368 of the Code (see "Certain Federal Income
                         Tax Consequences"  below).  However,  in the event that
                         the  receipt of such  opinions  is waived,  the parties
                         have agreed to amend this  Prospectus  to disclose  the
                         waiver  of this  condition  and any risks to URS and WC
                         stockholders  arising from such waiver,  and distribute
                         such amended  Prospectus to the stockholders of URS and
                         WC and resolicit URS and WC stockholder approval.
    

                         The Merger  Agreement  may be  amended by the  parties'
                         Boards  of  Director  at any time  before  or after the
                         approval of the Merger  Agreement by the URS and the WC
                         stockholders, but after such stockholder approvals have
                         been  obtained,  no amendment  that by law requires the
                         further  approval  of  such  stockholders  may be  made
                         without  such  approval.  See "The  Merger - The Merger
                         Agreement."

No-Shop;
Termination Fees         The Merger  Agreement  prohibits WC from  soliciting or
                         entertaining  any other  offers to acquire WC or all or
                         substantially  all its assets  unless the failure to do
                         so  would  breach  the  fiduciary   duties  of  the  WC
                         directors.  In the event that WC or any of its officers
                         or   directors   enters   into  any   negotiations   or
                         discussions  for any  reason in  breach of the  no-shop
                         provision  of the  Merger  Agreement,  WC has agreed to
                         immediately  reimburse  URS for all  expenses and costs
                         incurred by URS in connection  with the Merger up to an
                         aggregate maximum of $500,000.  In the event that WC or
                         any of its officers or directors enters into any letter
                         of intent,  agreement or  understanding  with any party
                         other  than  URS  relating  to  the  sale  of  all or a
                         substantial part of the assets, business or stock of WC
                         during the period  prior to the  Closing or within nine
                         months after  termination  of the Merger  Agreement for
                         any reason,  WC has agreed to pay URS a termination fee
                         of  $3,500,000,  less the  aggregate  amount of the URS
                         expenses and costs  previously  reimbursed  to URS. See
                         "The Merger - The Merger Agreement."

Accounting Treatment     The Merger is  expected  to be treated as a  "purchase"
                         under generally  accepted  accounting  principles.  See
                         "The Merger - Accounting Treatment."

   
Tax Consequences of
The Merger               URS and WC have received opinions from their respective
                         legal  counsel  to the effect  that the Merger  will be
                         treated as a  "reorganization"  within  the  meaning of
                         Section  368 of the Code,  so that no gain or loss will
                         be recognized by the WC stockholders on the exchange of
                         WC Capital  Stock for URS Common  Stock,  except to the
                         extent  that WC  stockholders  receive  cash in lieu of
                         fractional  shares  or  upon  exercise  of  dissenters'
                         rights.  In  addition,  gain,  but  not  loss,  will be
                         recognized  to the extent of cash  received in exchange
                         for WC  Capital  Stock,  but not in  excess of the gain
                         realized by a WC stockholder in the Merger.  The Merger
                         Agreement  does not  require  the  parties  to obtain a
                         ruling from the Internal Revenue Service (the "IRS") as
                         to the tax consequences of the Merger.  WC stockholders
                         are urged to consult  their own tax advisors  regarding
                         such  tax  consequences.   See  "The  Merger--  Certain
                         Federal Income Tax Matters."

Effect of Merger on
WC Plan  Participants    Upon  the  execution  of  the  Merger   Agreement,   WC
                         suspended any  obligation  to  contribute  shares of WC
                         Preferred Stock to, or to redeem shares of WC Preferred
                         Stock from,  the WC  Retirement  Plan during the period
                         from the date of the Merger  Agreement to the Effective
                         Time of the Merger.

                         WC  also  agreed,  at the  option  of  URS,  to  either
                         terminate  the  WC  Retirement   Plan  and/or  the  GCH
                         Acquisition Corp.  Retirement  Program (the "GCH Plan")
                         prior to the Effective  Time of the Merger and/or merge
                         the WC  Retirement  Plan and the GCH Plan with and into
                         the URS 401(k)  Retirement Plan (the "URS 401(k) Plan")
                         from the Effective Time of the Merger, and to eliminate
                         any options  available to the WC Retirement  Plan,  the
                         GCH Plan or their  participants  to  purchase  employer
                         securities  with assets held in the WC Retirement  Plan
                         or the GCH Plan from and after  the  Effective  Time of
                         the Merger.  In the event that either of these plans is
                         terminated,   participants  will  have  the  option  of
                         withdrawing  the balance of their accounts  (which will
                         be a taxable  event) or rolling  such  account  balance
                         into the URS  401(k)  Plan or  another  qualified  plan
                         (such as an IRA), which should not be taxed. WC and URS
                         are currently  exploring  potential  methods of merging
                         the WC Retirement Plan, the GCH Plan and the URS 401(k)
                         Plan in a transaction  to be made  effective  some date
                         after the Effective Date of the Merger.

Effect of Merger on
WC Bonus Plan            The  Merger  Agreement  also  provides  that  after the
                         Effective  Time of the  Merger,  URS will  complete  an
                         audit of the  consolidated  financial  statements of WC
                         for the period  beginning on January 1, 1997 and ending
                         on  the  Effective  Time  of  the  Merger  (the  "Bonus
                         Period").  Promptly  following  the  completion of such
                         audit,  URS will pay bonuses to the former employees of
                         WC in a manner  consistent  with prior  practices,  but
                         prorated for the Bonus Period. See "The Merger - Effect
                         on Existing WC Benefit Plans."

Dissenters' Rights       Holders of WC Capital  Stock have  rights to dissent to
                         the  Merger and seek a  judicial  determination  of the
                         value  of the  shares  of WC  Capital  Stock.  See "The
                         Merger - Rights of Dissenting Stockholders."

Management of URS
Following the Merger     The management of URS after the Merger will not change,
                         except  that after the  Effective  Time of the  Merger,
                         Messrs. Frank S. Waller and Jean-Yves Perez will become
                         executive  officers  and  directors  of URS.  See  "The
                         Merger - Directors  and  Executive  Officers  After the
                         Merger."

Merger Expenses and
Fees and  Other  Costs   URS  and  WC  estimate  that  they  will  incur  direct
                         transaction  costs  of  approximately   $10,000,000  in
                         connection  with the Merger.  See  "Unaudited Pro Forma
                         Combined Condensed Financial  Information."  Whether or
                         not the Merger is consummated, each party will bear its
                         own costs and  expenses in  connection  with the Merger
                         Agreement and the transactions provided for therein.

                   Selected Pro Forma Combined Financial Data

         The  following  unaudited  selected  pro  forma  historical   financial
information shown below is based on the historical  consolidated  balance sheets
and related consolidated statements of operations of URS and WC adjusted to give
effect to the  Merger  using the  purchase  method of  accounting  for  business
combinations.

         The unaudited pro forma combined condensed balance sheet as of July 31,
1997 assumes that the Merger  occurred as of that date.  The unaudited pro forma
combined condensed statement of operations for the fiscal year ended October 31,
1996 assumes that the Merger  occurred as of November 1, 1995. The unaudited pro
forma combined condensed  statement of operations for the nine months ended July
31, 1997  assumes that the Merger  occurred as of November 1, 1995.  In order to
present comparable data for the combining companies,  the pro forma statement of
operations  includes the historical  data for WC for the nine month period ended
June 30, 1997 and for the fiscal year ended December 31, 1996.

         This pro  forma  information  should  be read in  conjunction  with the
unaudited pro forma combined  condensed  financial  information  and the related
notes included in this Prospectus. The unaudited pro forma financial information
is not  necessarily  indicative of the operating  results or financial  position
that


                                       13

would have occurred had the Merger been  consummated  on the dates  indicated in
the preceding  paragraph nor is it  necessarily  indicative of future  operating
results or financial position of the combined companies.

                    Per Share Data - Historical and Pro Forma

         Set  forth  below  is  certain  common  share  data of URS and WC on an
historical  basis,  a pro forma basis for URS and an equivalent  pro forma basis
for WC. The URS pro forma data was derived by combining historical  consolidated
financial  information  of URS and WC,  giving  effect to the  Merger  under the
purchase  method of accounting  for business  combinations.  The  equivalent pro
forma common share data for WC was calculated by  multiplying  the URS pro forma
per common share data by the exchange ratio of 2.3174 (based on 1,964,175 shares
of WC Common Stock issued and  outstanding  on the WC Record Date,  and assuming
that the URS Closing  Price is $14.28 per share (the average daily closing price
for such  stock on the NYSE  over the 20  trading  days  preceding  the date the
Merger Agreement was signed)).

         On August 18, 1997, the last trading day prior to the  announcement  by
URS that it had executed the Merger  Agreement,  the closing price of URS Common
Stock, as reported in the WSJ, was $13.63. As of the URS Record Date, there were
approximately  2,819 stockholders of record who held shares of URS Common Stock,
as shown on the records of URS's transfer agent for such shares.

         Shares of WC Common  Stock are made  available  from time to time by WC
for  purchase by selected  professional  employees of WC at prices set by the WC
Board of Directors.  Since January 1, 1997,  the purchase  price has been set at
$25.00 per share. There is no public trading market for WC securities.  However,
WC  repurchases  such  securities  from  time to time upon the  satisfaction  of
certain  conditions.  Repurchases  are  made at the  same  purchase  price as is
determined  by the WC Board of Directors for sales of WC Common Stock by WC. See
"Information  Concerning WC - Market Price of and Dividends on Common Equity and
Related Stockholder Matters." As of the WC Record Date, there were approximately
490  stockholders  of  record  who  held  shares  of WC  Common  Stock  and  one
stockholder of record who held shares of WC Preferred Stock.

                                 Dividend Policy

         URS has not paid cash  dividends  since 1986 and at the  present  time,
management  of URS does not  anticipate  paying  dividends  in the near  future.
Further,  URS is precluded from paying dividends on its outstanding common stock
pursuant  to its  existing  secured  credit  agreement  and the terms of the new
credit arrangement contemplated by the Commitment Letter (as defined below).



                                       16

         WC has never paid dividends on the WC Common Stock.  Under the terms of
its Financing  Agreement  dated  September 23, 1996 with The CIT  Group/Business
Credit,  Inc.  (the "WC  Financing  Agreement"),  WC and  certain  of its  major
subsidiaries  are  prohibited  from paying any  dividends on their capital stock
without the prior written consent of the agent of the lenders. It is anticipated
that all indebtedness outstanding under the WC Financing Agreement will be fully
paid  and that the WC  Financing  Agreement  will be  terminated  following  the
consummation of the Merger.

As of the close of business on the URS Record Date, there were 10,746,244 shares
of URS  Common  Stock  outstanding  and  entitled  to vote,  held of  record  by
approximately 2,819  stockholders.  Each URS stockholder is entitled to one vote
for each share of URS Common Stock held as of the URS Record Date.

         Each  holder of record of URS Common  Stock on the URS Record Date will

votes will be tabulated by the inspector of election  appointed for the meeting,
who will separately  tabulate  affirmative  and negative votes,  abstentions and
broker non-votes.  Abstentions and broker non-votes are counted towards a quorum
but are not counted for any purpose in determining whether a matter is approved.

Voting of Proxies

         The URS proxy  accompanying  this  Prospectus is solicited on behalf of
the  Board of  Directors  of URS for use at the URS  Meeting.  Stockholders  are
requested to complete,  date and sign the accompanying proxy and promptly return
it in the  accompanying  envelope or otherwise  mail it to URS. All proxies that
are properly executed and returned,  and that are not revoked,  will be voted at
the URS Meeting in accordance with the instructions indicated on the proxies or,
if no direction is indicated,  to approve the Merger  Agreement.  URS's Board of
Directors does not presently intend to bring any business before the URS Meeting
other than the specific  proposals  referred to in this Prospectus and specified
in the  notice  of the  URS  Meeting.  So far as is  known  to  URS's  Board  of
Directors,  no other matters are to be brought before the URS Meeting. As to any
business that may properly come before the URS Meeting,  however, it is intended
that  proxies,  in the  form  enclosed,  will be  voted in  respect  thereof  in
accordance  with  the  judgment  of  the  persons  voting  such  proxies.  A URS
stockholder  who has  given a proxy  may  revoke  it at any  time  before  it is
exercised at the URS Meeting,  by (i) delivering to the Secretary of URS (by any
means, including facsimile) a written notice, bearing a date later than the date
of the proxy, stating that the proxy is revoked,  (ii) signing and so delivering
a proxy  relating  to the same shares and bearing a later date prior to the vote
at the URS  Meeting,  or (iii)  attending  the URS  Meeting and voting in person
(although attendance at the URS Meeting will not, by itself, revoke a proxy).

Vote Required

         Approval of the Merger Agreement will require the affirmative vote of a
majority of the outstanding shares of URS Common Stock.

is a majority of the shares of Common Stock  outstanding on the URS Record Date.
Abstentions and broker non-votes each will be included in determining  whether a
quorum is present.  Abstentions  will be counted towards the tabulation of votes
cast.  Abstentions  will  have the same  effect  as a vote  against  the  Merger
Agreement.  Broker  non-votes will not be counted for any purpose in determining
whether the proposal to approve the Merger has been approved.

Solicitation of Proxies and Expenses

         URS will bear the entire cost of the solicitation of proxies, including
preparation,  assembly,  printing and mailing of this Prospectus,  the proxy and
any  additional  information  furnished  to  its  stockholders.  Copies  of  the

and custodians  holding in their names shares of URS's Common Stock beneficially
owned by others to forward to such beneficial  owners. URS may reimburse persons
representing  beneficial  owners of Common  Stock for their costs of  forwarding
solicitation  materials to such  beneficial  owners.  Original  solicitation  of
proxies by mail may be supplemented by telephone,  telegram,  letter or personal
solicitation  by  directors,  officers,  or other  regular  employees of URS. No
additional  compensation  will be paid to directors,  officers and other regular
employees for such services.

Board Recommendation

         THE BOARD OF DIRECTORS  OF URS BELIEVES  THAT THE MERGER IS FAIR TO AND
IN THE BEST  INTERESTS OF URS AND ITS  STOCKHOLDERS  AND  THEREFORE  UNANIMOUSLY
RECOMMENDS A VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

         The  enclosed  proxy and consent is solicited on behalf of the Board of
Directors of WC for use at the WC Meeting,  or at any adjournment  thereof.  Any

person.

Record Date and Outstanding Shares

         Only  stockholders  of record at the close of business on the WC Record

Record Date, there were 1,964,175 shares of WC Common Stock and 44,898 shares of
WC  Preferred  Stock  outstanding  and  entitled to vote.  WC  stockholders  are
entitled to one vote for each share of Common  Stock and one vote for each share
of WC Preferred Stock held on the Record Date. All of the outstanding  shares of
WC  Preferred  Stock  are  held  by the  General  Trustees  of  the  WC  Capital
Accumulation (Retirement) Plan, who are currently Frank S. Waller, James R.
Obermeyer and Richard L. Fuller.

Voting of Proxies

         The WC proxy and consent  accompanying  this Prospectus is solicited on
behalf of the Board of Directors  of WC for use at the WC Meeting.  Stockholders
are requested to complete,  date and sign the accompanying proxy and consent and
promptly return it in the accompanying  envelope or otherwise mail it to WC. The
signature of a  stockholder  of WC Common Stock on a returned  proxy and consent
voted  in favor of the  Merger  Agreement  will  constitute  such  stockholder's
written  consent to the amendment of the  Shareholders'  Agreement,  as required
therein.  All proxies and consents that are properly executed and returned,  and
that are not  revoked,  will be voted at the WC Meeting in  accordance  with the
instructions  indicated  on the  proxies and  consents  or, if no  direction  is
indicated,  to approve the Merger  Agreement.  WC's Board of Directors  does not
presently  intend to bring any  business  before the WC  Meeting  other than the
specific proposals referred to in this Prospectus and specified in the notice of
the WC Meeting. So far as is known to WC's Board of Directors,  no other matters
are to be brought  before the WC Meeting.  As to any business  that may properly
come before the WC Meeting,  however,  it is intended that proxies and consents,
in the form enclosed,  will be voted in respect  thereof in accordance  with the
judgment of the persons voting such proxies and consents. Any WC stockholder who
has given a proxy and consent  may revoke it at any time before it is  exercised
at the WC  Meeting,  by (i)  delivering  to the  Secretary  of WC (by any means,
including facsimile) a written notice, bearing a date later than the date of the
proxy and consent,  stating that the proxy and consent is revoked,  (ii) signing
and so delivering a proxy and consent  relating to the same shares and bearing a
later  date  prior to the vote at the WC  Meeting,  or  (iii)  attending  the WC
Meeting and voting in person (although attendance at the WC Meeting will not, by
itself, revoke a proxy and consent).

Vote Required

         Approval of the Merger  Agreement by WC stockholders is required by the
Delaware General Corporation Law and the WC Certificate. In addition, the Merger
Agreement  requires as a condition of closing that the Merger  Agreement and the
Merger have been duly  approved by the  affirmative  vote of at least (a) 70% of
the shares of WC Common Stock  outstanding  on the WC Record  Date,  voting as a
separate  class  and  (b)  a  majority  of  the  shares  of WC  Preferred  Stock
outstanding on the WC Record Date,  voting as a separate class.  See "The Merger
The Merger Agreement."

         The   Shareholders'   Agreement   does  not  expressly   contemplate  a
transaction  such as the Merger,  and contains  certain rights of first refusal,
transfer  restrictions  and  other  provisions  which  could  interfere  with or
complicate  consummation  of  the  Merger.  Accordingly,  the  Merger  Agreement
contemplates  amending  the  Shareholders'  Agreement  in such  manner as may be
necessary  to  permit  consummation  of  the  Merger  without   interference  or
complication.  At the Effective Time of the Merger, the Shareholders'  Agreement
would then be terminated  and have no further force or effect.  The amendment of
the  Shareholders'  Agreement in this manner  requires the  affirmative  vote of
holders of 70% of the  shares of WC Common  Stock  outstanding  on the WC Record
Date.  The signature of a stockholder of WC Common Stock on a returned proxy and
consent  voted  in  favor  of  the  Merger   Agreement  will   constitute   such
stockholder's  written consent to the amendment of the Shareholders'  Agreement,
as required therein.

         All of WC's directors and executive  officers who are stockholders have
indicated  that they will vote their shares of WC Capital Stock for the approval
of the Merger Agreement and the amendment of the Shareholders'  Agreement at the
WC  Meeting.  All of  the  General  Trustees  of  the  WC  Capital  Accumulation
(Retirement)  Plan have indicated that they will vote the shares of WC Preferred
Stock for approval of the Merger  Agreement at the WC Meeting.  At the WC Record
Date,  the directors and executive  officers of WC as a group hold 15.02% of the
outstanding  shares of WC Common Stock. As of the WC Record Date and the date of
this Prospectus, URS owns no shares of WC Capital Stock.

Quorum; Abstentions

         The required  quorum for the  transaction of business at the WC Meeting
is a majority  of the shares of WC Common  Stock and a majority of the shares of
WC  Preferred  Stock  outstanding  on the WC Record  Date.  Abstentions  will be
counted for purposes of determining the presence of a quorum.  Abstentions  will
be counted towards the tabulation of the votes cast.  Abstentions  will have the
same effect as a vote  against the Merger  Agreement  and the  amendment  of the
Shareholders' Agreement.

Solicitation of Proxies and Expenses

         WC will bear the cost of  solicitation  of proxies in the enclosed form
from its  stockholders.  In addition to  solicitation  by mail,  the  directors,
officers and employees of WC may solicit proxies from stockholders by telephone,
telegram, telecopy, letter or in person.

Board Recommendation

THE BOARD OF DIRECTORS OF WC BELIEVES THAT THE MERGER IS FAIR TO AND IN THE BEST
INTERESTS OF WC AND ITS STOCKHOLDERS AND THEREFORE UNANIMOUSLY RECOMMENDS A VOTE
FOR THE APPROVAL OF THE MERGER  AGREEMENT  AND  AMENDMENT  OF THE  SHAREHOLDERS'
AGREEMENT.  STOCKHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY
CARDS.

                                  RISK FACTORS

         The  following  risk  factors  should be  considered  by  holders of WC
Capital Stock in evaluating  whether to approve the Merger Agreement and thereby
become  holders of URS  Common  Stock,  and by  holders  of URS Common  Stock in
evaluating  whether to approve the  acquisition of WC and the issuance of shares
of URS Common Stock  pursuant to the Merger  Agreement.  These factors should be
considered  in  conjunction  with  the  other   information   included  in  this
Prospectus.

         Except for the historical  information  contained herein, the following
discussion   contains   forwardlooking   statements   that  involve   risks  and
uncertainties. URS's actual results could differ materially from those discussed
here.  Factors that could cause or contribute to such differences  include,  but
are not limited to, those discussed in "Risk Factors" as well as in the sections
entitled   "Summary,"   "Unaudited  Pro  Forma  Condensed   Combined   Financial
Information," "Business of URS," "Business of WC," "Management's  Discussion and
Analysis  of  Financial   Condition  and  Results  of  Operations  of  URS"  and
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations of WC."

Joint Risk Factors

Merger of WC and URS

         The  respective  Boards  of  Directors  and  managements  of URS and WC
believe  that the  combination  of the  companies is important to the growth and
development  of  their  business  domestically  and  worldwide.   Achieving  the
anticipated  benefits of the  acquisition  will depend in part upon  whether the
integration of the two companies' businesses is accomplished in an efficient and
effective  manner.  Although the management teams of the two companies are fully
committed to a successful integration,  there can be no assurance that this will
occur.  The  inability of  management  to integrate  the  operations  of the two
companies successfully, including but not limited to, failure to retain existing
clients and employees of both companies, could have a material adverse effect on
the combined enterprise.

URS Risk Factors

Dependence Upon Government Programs and Contracts

         URS derives more than eighty percent of its revenues from local,  state
and  Federal  government  agencies.  The demand for URS's  services  is directly
related to the level of  funding  of  government  programs  that are  created in
response  to  public   concern  with   rebuilding  and  expanding  the  nation's
infrastructure and addressing various environmental  problems. URS believes that
the success and further development of its business is dependent, in significant
part,  upon the continued  existence and funding of such programs and upon URS's
ability to participate  in such programs.  There can be no assurance that public
pressure  for such  programs  will  continue,  that  governments  will  have the
available  resources to fund such programs,  that such programs will continue to
be funded even if governments have available  financial  resources,  or that URS
will  continue to be awarded  contracts  under such  programs.  More than eighty
percent  of  URS's  current  and  anticipated  work  is  related  to  government
contracts. Some of these contracts are subject to renewal or extension annually,
so continued work by URS under these contracts in future periods is not assured.
In addition,  contracts with government  agencies are subject to termination for
convenience  of the agency,  and contracts  with  government  agencies that have
adopted Federal Acquisition  Regulations are subject to an audit of actual costs
incurred  and provide for upward or downward  adjustment  of payments if audited
costs differ from billed costs.



                                       22

<PAGE>



Pricing Risks

         URS's  services are billed on either a "cost-plus"  or a  "fixed-price"
basis. Under cost-plus contracts,  the rates for URS's direct and indirect costs
are negotiated and fixed before work commences. Under fixed-price contracts, the
entire  contract price is fixed before work commences.  Frequently,  URS submits
proposals on extremely  complex  projects that will be performed over the course
of several years,  making the accurate  forecasting of costs very difficult.  To
the extent that URS's  actual  overhead  and general  and  administrative  costs
exceed  government  limits and cannot be fully recovered,  or the scope of URS's
work cannot be completed  within its  original  budget and a  supplemental  work
order cannot be obtained, URS could experience low profit margins or losses on a
portion of both its cost-plus and fixed-price contracts.

Environmental and Professional Liability Exposure;
Adequacy of Insurance Coverage

         A significant part of URS's business involves the planning,  design and
program and construction  management of a wide variety of complex  projects.  If
problems develop with these projects,  either while under  construction or after
they have been  completed,  claims may be made  against URS  alleging  breach of
contract or negligence  in the  performance  of its  professional  services.  In
addition,  URS's professional services involve the planning,  design and program
and  construction   management  of  waste   management  and  pollution   control
facilities.  Federal laws, such as the Resource Conservation and Recovery Act of
1976 ("RCRA") and the  Comprehensive  Environmental  Response,  Compensation and
Liability Act of 1980  ("CERCLA"),  and various  state and local laws,  strictly
regulate  the  handling,  removal,  treatment  and  transportation  of toxic and
hazardous substances and impose liability for environmental contamination caused
by such  substances.  Moreover,  so-called "toxic tort" litigation has increased
markedly in recent years as those injured by hazardous  substances seek recovery
for personal  injuries or property  damage under common law theories.  While URS
does not  directly  handle,  remove,  treat  or  transport  toxic  or  hazardous
substances,  some of URS's  contracts  require  URS to design  systems for those
functions or to subcontract  for or supervise  such work. As a consequence,  URS
may be exposed  to claims  for  damages  caused by  environmental  contamination
arising from projects on which URS has worked.  Currently, URS has $51.0 million
per occurrence and aggregate  commercial general liability  insurance  coverage.
URS is also insured for professional errors and omissions ("E&O") and contractor
pollution  liability  ("CPL")  claims with an aggregate  limit of $30.0  million
after a self-insured retention of $0.5 million. The E&O and CPL coverages are on
a "claims  made" basis,  covering  only claims  actually  made during the policy
period  currently in effect.  Thus,  if URS does not  continue to maintain  this
policy,  it will have no  coverage  under the policy  for claims  made after its
termination  date even if the occurrence was during the term of coverage.  It is
URS's intent to maintain  this type of  coverage,  but there can be no assurance
that URS can  maintain its  existing  coverage,  that claims will not exceed the
amount of insurance  coverage or that there will not be claims relating to prior
periods that were subject only to "claims made" coverage.

Attraction and Retention of Qualified Professionals

         URS's  ability to retain and  expand its staff of  qualified  technical
professionals  will be an important factor in determining  URS's future success.
There is from time to time a shortage of qualified  technical  professionals  in
various fields.  The market for engineering and  environmental  professionals is
competitive  and  there  can  be no  assurance  that  URS  will  continue  to be
successful in its efforts to attract and retain such professionals. In addition,
URS relies heavily upon the experience and ability of its


                                       23

senior executive staff and the loss of a significant portion of such individuals
could have a material adverse effect on URS.

Principal Stockholders

         As of September 5, 1997, URS has 10,594,025  shares of URS Common Stock
outstanding (assuming no exercise of options after such date). Richard C. Blum &
Associates,  Inc. ("RCBA Inc.") is the sole general partner of Richard C. Blum &
Associates,  L.P. ("RCBA L.P."),  which is, in turn, the sole general partner of
BK Capital  Partners I, L.P., BK Capital  Partners II, L.P., BK Capital Partners
III, L.P. and BK Capital  Partners IV, L.P., and the  investment  advisor to The
Common  Fund.  Accordingly,  as of the date  hereof,  RCBA Inc.  has  voting and
dispositive  control with  respect to an  aggregate  of 2,933,888  shares of URS
Common  Stock,  or  approximately  28% of the  outstanding  shares of URS Common
Stock.  Richard C. Blum,  Vice Chairman of the Board of Directors of URS, is the
majority  shareholder  of RCBA Inc. and directly owns 8,833 shares of URS Common
Stock, is the beneficiary of a Keogh Plan which holds 2,454 shares of URS Common
Stock,  and holds options to purchase  9,000 shares of URS Common Stock,  all of
which are currently exercisable.

         URS's principal lender,  Wells Fargo Bank, National Association ("Wells
Fargo"),  holds  an  aggregate  of  724,371  shares  of  URS  Common  Stock,  or
approximately  7% of the  outstanding  shares of URS Common Stock.  In addition,
several  institutional  investors,  Heartland Advisors,  Inc.,  Dimensional Fund
Advisors,  Inc. and FMR Corp.,  hold an  aggregate  of  3,379,561  shares of URS
Common  Stock,  or  approximately  32% of the  outstanding  shares of URS Common
Stock.

Volatility; Market for the Shares

         Shares of URS Common  Stock are listed for  trading on the NYSE and the
PE. URS Common Stock has been thinly traded,  which may have caused  substantial
fluctuations  in the  market  price of the  Shares.  Fluctuations  in  quarterly
financial  results and general  economic  conditions  such as recessions or high
interest  rates may also cause the market price of URS Common Stock to fluctuate
substantially.

Competition

         The   architectural   and  engineering   services  industry  is  highly
fragmented and very competitive.  As a result, in each specific market area, URS
competes  with many  engineering  and  consulting  firms,  several  of which are
substantially  larger than URS and which possess  greater  financial  resources.
Competition is based upon reputation,  quality of service,  price, expertise and
local presence.

WC Risk Factors

Weakness in 1996 Operating Results

         WC's  consolidated 1996 financial  statements  reflect a decline in net
revenue from 1995 levels,  due, in part, to a reduction in  consulting  revenues
from domestic  private  industry  clients and revenues  from Federal  government
projects.  These  declines  were partly due to the negative  impact of delays in
implementation  of Federal  environmental  legislation,  and to price  discounts
offered  by  WC to  remain  competitive.  WC's  international  and  construction
businesses also had negative effects on WC's operating results. While net income
reported for the first six months of 1997 increased  over 1996,  there can be no
assurance  that the  conditions  which  existed in 1996 will not reoccur,  which
would have a material adverse effect on WC.



                                       24

<PAGE>



Attraction and Retention of Professional Personnel

         WC's future success depends upon the continued  service of numerous key
engineering,   scientific  and  executive   personnel.   The  market  for  these
professionals is competitive.  There can be no assurance that WC will be able to
continue to attract and retain qualified personnel necessary for the maintenance
and development of its business. Loss of the services of, or failure to recruit,
key engineering and scientific personnel could have a material adverse effect on
WC.

Professional and Environmental Liability Exposure;
Adequacy of Insurance Coverage

         In a  similar  fashion  to  those  of URS  discussed  previously,  WC's
consulting services, especially those relating to toxic and hazardous materials,
involve significant risks of professional and other liability.  WC is subject to
claims against it for breach of contract or negligence in the performance of its
professional  planning,  design,  and program  and  construction  management  of
complex  projects.  WC's services are involved in waste management and pollution
control  facilities,  and WC is  therefore  also  subject to RCRA,  CERCLA,  and
various state and local laws  regulating  the handling,  removal,  treatment and
transportation  of toxic and hazardous  substances,  the imposition of liability
for environmental  contamination caused by such substances,  and by "toxic tort"
litigation.  WC is  actively  engaged in  planning  and  design,  as well as the
construction of environmental  remediation  projects. As a result, WC is subject
to exposure to claims for damages caused by environmental  contamination arising
from projects on which WC has worked.

         WC was founded as a geotechnical  engineering  firm and has continually
maintained a prominent geotechnical practice, which now represents approximately
23% of its business.  This area of professional  practice has traditionally been
viewed by the insurance industry as one involving a high professional  liability
exposure.  Much of this risk,  however,  has been  associated  with  residential
housing  development,  a practice  from which WC withdrew  in the early  1980's.
While the  company  maintains  strong  risk  management  and  quality  assurance
programs,  there is inherent risk associated with the  geotechnical  practice in
which the firm continues to be engaged,  particularly  related to large projects
such as dams, tunnels, and other earthworks.

         WC maintains insurance coverage,  including  professional liability and
environmental  impairment  coverage,  for its  operations.  Although WC's excess
errors and omissions  ("E&O") and  pollution  coverage is procured from standard
insurance   providers,   approximately  the  first  $4,000,000  of  professional
liability risks for each claim year, and  approximately  the first $1,000,000 of
contractors  pollution  risks for each  claim  year,  are  carried  through  its
wholly-owned  captive insurance  subsidiary,  Montgomery Group, Ltd. ("MGL"),  a
Bermuda  insurance  company.  MGL's sole  business  purpose  is to provide  this
insurance to WC. In terms of financial risk, a captive insurance program such as
this is the  equivalent  of  managing a very large  deductible  or  self-insured
retention ("SIR") and requires special  procedures for setting and updating loss
reserves within the limit of the SIR. While WC believes that its reserve setting
and reserve  funding  provisions  are adequate,  there can be no assurance  that
covered  losses  within this  primary  layer of  self-insurance  will not exceed
established  reserves.  There can be no  assurance  that  insurance  above  that
portion borne by MGL will continue to be available, or that the dollar amount of
WC's  liabilities  will not exceed the insurance  policy  limits.  The continued
availability  and cost of  insurance  will depend upon  market  conditions,  the
claims  record of WC and the claims  experience of the insurers  providing  such
coverage.



                                       25

<PAGE>



Competition

         As noted above with respect to the  business of URS, the  architectural
and engineering services industry is highly fragmented and very competitive, and
as a result WC competes with many firms, some of which are substantially  larger
and  possess  greater  financial  resources,   in  all  of  its  service  areas.
Competition in these service areas is based upon reputation, quality of service,
price, expertise and local presence. Furthermore, given the expanding demand for
the types of services  provided by WC, it is likely that additional  competitors
will emerge.  WC has  occasionally  found it necessary to provide  discounts and
lower  prices  for its  services  in order to retain its  competitive  position,
which, in 1996 in particular,  affected WC's revenues and results of operations.
There can be no assurance that the amount and quality of competition will not at
some point again require action which adversely  affects revenues and results of
operations.

Dependence upon Government Programs and Contracts

         Much of WC's business is generated  either  directly or indirectly as a
result  of  Federal  and  state  laws,   regulations  and  programs  related  to
environmental  issues. WC derived more than 36% of its revenues during 1996 from
local,  state and  Federal  government  agencies.  Demand for such  services  is
directly related to the level of government funding of infrastructure rebuilding
and expansion and in connection with  environmental  problems.  WC believes that
the success and further development of its business is dependent, in significant
part,  upon the  continued  existence  and funding of such programs and upon its
ability to participate  in such programs.  There can be no assurance that public
pressure  for such  programs  will  continue,  that  governments  will  have the
available  resources to fund such  programs  (especially  in light of the budget
constraints currently existing at all levels of government),  that such programs
will  continue to be funded,  or that WC will be awarded such work. In addition,
contracts with government agencies are subject to termination for convenience of
the agency and contracts  with  government  agencies  that have adopted  Federal
Acquisition  Regulations  are  subject  to audit of actual  costs  incurred  and
provide for upward or downward  adjustment  of payments if audited  costs differ
from billed costs.

Pricing Risks

         A substantial amount of WC's services, like those of URS, are billed on
either a "cost-plus" or a  "fixed-price"  basis,  and the risk factors set forth
above  regarding  URS's risks with respect to project  financing  apply to WC as
well. Like URS, WC submits  proposals on extremely complex projects that will be
performed over the course of several years, which make the accurate  forecasting
of costs very  difficult.  In the recent past, WC experienced low profit margins
or  losses on a  portion  of both of its  cost-plus  and  fixed-price  contracts
because overhead and general and administrative costs exceeded government limits
and could not be fully  recovered  or the scope of work  could not be  completed
within the original budget and a supplemental  work order could not be obtained.
To the extent WC does not control overhead, general and administrative costs, or
underestimates such costs, it may have low profit margins, or incur losses.

         In April,  1995, WC acquired Geo-Con,  Inc.  ("Geo-Con"),  a contractor
specializing in geotechnical  construction projects,  such as slurry walls, deep
soil mixing, trenching, landfill construction,  and hazardous waste remediation.
Through the  following  eighteen-month  period,  Geo-Con  sustained  substantial
losses on projects which were underway when the  acquisition  occurred.  Most of
Geo-Con's  work is  performed  under  fixed-price  or lump sum  contracts  where
projects  are  awarded to the low bidder and losses may result if the low bidder
is unable to perform the required work within the amount of the


                                       26

<PAGE>



bid. The industry is very competitive and the projects  typically will have some
inherent  risks that may exceed  contingencies  included in the bid.  Therefore,
there is a continuing risk that project costs may exceed contract amounts.

International Operations

         WC derived  approximately  21% of its revenue in 1996 from  offices and
projects outside the U.S. Most of this  international  work,  approximately 91%,
has  consisted  in the past and is  expected  to  continue to consist of work in
Australia,  New Zealand,  Europe and Canada, where it is performed by WC offices
that are  well-established  in those  countries.  The remaining  portion of WC's
international  work,  however,  consisted  of, and is  expected  to  continue to
consist  of,  project  work in  countries  where  WC has not had an  established
presence and which may entail political and economic risks,  including political
instability  and/ or  expropriation.  WC's  substantial  capital  investment  in
developing  its  international  practice,  made over the  course of the past ten
years,  has been  driven  in part by the  desire  to be able to  provide  global
service to its  multinational  clients.  The  profitability  of this practice in
certain areas remains to be established.  WC's international operations are also
subject to certain risks, including currency controls and fluctuations,  changes
in interest rates,  and loss or  modification  of any applicable  exemptions for
taxes and tariffs, which could have a material adverse effect on WC.

Domestic and International Economic Conditions

         Due  to  the  broad   geographic  sweep  of  its  current  and  planned
operations,  WC's business is subject to general economic conditions both in the
United  States and in other regions of the world in which it currently and plans
in the future to have significant operations.  A significant decline in economic
conditions in any one of these  geographic  areas could have a material  adverse
effect on WC.

                                   THE MERGER

         The  description  of the Merger and the  principal  terms of the Merger
Agreement  in this  Prospectus  is subject to and  qualified  in its entirety by
reference to the Merger Agreement, a copy of which is attached as Appendix A and
incorporated  herein by  reference.  This  section of this  Prospectus  contains
information  furnished  by the  Board of  Directors  of URS and by the  Board of
Directors  of WC in  connection  with the URS Meeting and the WC Meeting for the
purpose of obtaining stockholder approval of the Merger Agreement.

         The Merger Agreement contains certain  representations and covenants of
URS,  Acquisition  Corp. and WC, certain  conditions to the  consummation of the
Merger,  and other  terms and  provisions  respecting  the  Merger  and  related
transactions.  Capitalized  terms which are used but not defined in this section
have the meanings assigned in the Merger Agreement.

SUMMARIES OF CERTAIN  PROVISIONS OF THE MERGER AGREEMENT SET FORTH HEREIN DO NOT
PURPORT TO BE COMPLETE AND ARE  QUALIFIED IN THEIR  ENTIRETY BY REFERENCE TO THE
PROVISIONS  OF THE MERGER  AGREEMENT,  A COPY OF WHICH IS ATTACHED AS APPENDIX A
AND INCORPORATED  HEREIN BY REFERENCE.  ALL URS AND WC STOCKHOLDERS ARE URGED TO
READ THE MERGER AGREEMENT IN ITS ENTIRETY.

General

         On August 18,  1997,  URS, WC and  Acquisition  Corp.  entered into the
Merger  Agreement,  which sets forth the terms and  conditions of the Merger.  A
copy of the Merger  Agreement is included in this  Prospectus as Appendix A. The
Merger will be consummated promptly after the necessary approvals of the URS and
WC stockholders  have been obtained and the other  conditions to consummation of
the Merger have been satisfied or waived.  Upon  consummation of the Merger,  WC
will merge with and into  Acquisition  Corp. The  stockholders of WC will become
stockholders of URS (as described  below),  and their rights will be governed by
URS's Amended and Restated Certificate of Incorporation and Bylaws.
See "The Merger."

         By virtue of the Merger,  each of the shares of WC Capital Stock issued
and  outstanding  immediately  prior to the  Effective  Time of the Merger  (see
"Effective Time of the Merger" below) will  automatically  be converted into and
exchanged for the right to receive, in the aggregate, the Merger Consideration.

Effective Time of the Merger

         The Merger will become  effective upon the filing of articles of merger
or other  appropriate  documents  (the  "Merger  Documents")  with the  Delaware
Secretary of State.  The Merger  Agreement  provides that the parties will cause
the Merger Documents to be filed as soon as practicable  after the Closing Date,
which will be the first date after  approval of the Merger  Agreement  by the WC
stockholders  and the URS  stockholders  on which all conditions to the parties'
obligations to close the Merger have been satisfied or waived.  The parties have
agreed to use their  best  efforts  to do all  things  necessary  to permit  the
closing of the Merger,  but there can be no  assurance as to whether or when the
Merger will become effective.



                                       28

Merger Consideration

         As a result  of the  Merger,  the  shares of WC  Common  Stock  will be
converted into the right to receive, in the aggregate,  $91,693,870,  consisting
of  $26,693,870  in cash and  shares  of URS  Common  Stock  with a value at the
Effective  Time of the Merger of $65 million,  subject to  adjustment in certain
circumstances  as  described  below.  The value of the URS Common  Stock will be
determined on the basis of the average daily closing price for such stock on the
NYSE over the 20 trading  days  preceding  the  closing of the Merger  (the "URS
Closing  Price").  However,  in no event will the total  number of shares of URS
Common  Stock to be issued to the holders of WC Common  Stock as a result of the
Merger exceed 5,200,000 shares or be less than 4,044,804  shares.  Consequently,
even if the URS Closing Price is greater than $16.07 (the price  resulting  from
dividing $65 million by the minimum number of shares of URS Common  Stock),  the
holders of WC Common  Stock  will  receive,  in the  aggregate,  the  minimum of
4,044,804  shares of URS Common Stock (which will have a value  greater than $65
million)  and  also  will be  entitled  to  receive  the  $26,693,870  in  cash.
Conversely,  if the URS Closing  Price is less than $12.50 (the price  resulting
from dividing $65 million by the maximum  number of shares of URS Common Stock),
the holders of WC Common Stock will receive,  in the  aggregate,  the maximum of
5,200,000  shares of URS  Common  Stock  (which  will have a value less than $65
million),  but in this event the cash  component  of the  consideration  will be
increased so that the sum of the value of the shares of URS Common Stock and the
cash to be  received  by the  holders of the WC Common  Stock  will still  equal
$91,693,870.

         The  aggregate  consideration  to be  received by the holders of the WC
Common Stock as a result of the Merger will be allocated  among such holders pro
rata based on the number of shares of WC Common Stock held so that the aggregate
consideration  to be received in exchange for each share of WC Common Stock will
be  equal.  Based  on  the  1,964,175  shares  of WC  Common  Stock  issued  and
outstanding  on the WC Record Date,  and assuming  that the URS Closing Price is
$14.28 per share (the  average  daily  closing  price for such stock on the NYSE
over the 20 trading days  preceding  the date the Merger  Agreement was signed),
each  share of WC Common  Stock  would be  converted  into the right to  receive
$13.59 in cash and  2.317  shares  of URS  Common  Stock,  which  would  have an
indicated aggregate value of $46.68 per share of WC Common Stock. Based on these
assumptions and the 10,746,244 shares of URS Common Stock issued and outstanding
on the URS Record Date, WC stockholders  would receive an aggregate of 4,550,993
shares of URS Common  Stock as a result of the  Merger,  which  would  represent
29.75% of the outstanding URS Common Stock following the Merger.

         The shares of WC Preferred  Stock, all of which are held by the General
Trustees of the WC Retirement  Plan, will be converted into the right to receive
$8,306,130 in the aggregate in cash, which will be payable upon the surrender of
the  certificate(s)  formerly  representing such share of WC Preferred Stock. No
interest  will  accrue or be payable  with  respect  to the cash  portion of the
Merger Consideration. Pursuant to an agreement dated May 15, 1992 between WC and
the General Trustees of the WC Retirement  Plan, WC is entitled,  at its option,
to repurchase all of the outstanding WC Preferred Stock from the holders thereof
at a purchase  price of  $8,306,130,  which is  equivalent to the portion of the
Merger Consideration being offered for the WC Preferred Stock.

         Each of the  holders  of WC  Common  Stock  and WC are  parties  to the
Shareholders'  Agreement.  The Shareholders'  Agreement  restricts holders of WC
Common  Stock  from   transferring   their  shares  except  in  certain  limited
circumstances and to parties  acceptable under the Shareholders'  Agreement.  In
addition to other matters, the Shareholders' Agreement also provides each of the
holders of WC Common Stock with a right to require WC to purchase  their shares,
and provides WC with the right to require the holders of WC Common Stock to sell
such shares to WC if certain circumstances are met. Certain terms


                                       29

<PAGE>



of the  Shareholders'  Agreement  would prohibit the  transactions  necessary to
effect the Merger. Therefore, stockholders attending the WC Meeting in person or
by proxy are being asked to approve the amendment of the Shareholders' Agreement
to remove all restrictions and requirements  which would prohibit or prevent the
transactions contemplated by the Merger Agreement.

         No  fractional  shares of URS Common Stock will be issued in connection
with the Merger.  Fractional shares otherwise issuable will be settled for cash,
without  interest,  based on the closing  price per share of URS Common Stock as
quoted in WSJ on the trading day immediately preceding the Closing Date.

Conversion and Exchange of WC Common Stock Certificates

         As soon as practicable  after the Effective  Time of the Merger,  Chase
Mellon Shareholder  Services,  LLC, URS's exchange agent (the "Exchange Agent"),
will send a notice and  transmittal  form to each holder of WC Capital  Stock of
record  at the  Effective  Time  of  the  Merger  advising  such  holder  of the
effectiveness  of the Merger and the procedure for  transferring  shares held in
book entry form and for  surrendering  to the  Exchange  Agent any  certificates
formerly  evidencing WC Capital  Stock.  WC  STOCKHOLDERS  SHOULD NOT SEND THEIR
STOCK  CERTIFICATES TO THE EXCHANGE AGENT OR WC UNTIL THEY RECEIVE THE LETTER OF
TRANSMITTAL FORM AND INSTRUCTIONS FROM THE EXCHANGE AGENT.

         Upon the  surrender to the Exchange  Agent of one or more  certificates
formerly  evidencing WC Capital  Stock,  together with a properly  completed and
signed  letter of  transmittal,  there  will be issued  and mailed to the holder
thereof a new  certificate  or  certificates  representing  the  number of whole
shares of URS Common  Stock to which such  holder is  entitled  under the Merger
Agreement,  a check for the amount of cash  payable for each share of WC Capital
Stock, and, where applicable,  a check for the amount of cash payable in lieu of
a fractional  share of URS Common Stock. A certificate  representing  URS Common
Stock or a check in lieu of a  fractional  share  will be issued in a name other
than the  name in  which  the  surrendered  WC  Capital  Stock  certificate  was
registered only if (i) the WC Capital Stock certificate  surrendered is properly
endorsed or accompanied  by appropriate  stock powers and is otherwise in proper
form for  transfer,  and (ii) the person  requesting  the issuance of such stock
certificate  or check  either pays to the  Exchange  Agent any transfer or other
taxes  required or establishes  to the  satisfaction  of the Exchange Agent that
such tax has been paid or is not applicable.

Description of URS Capital Stock

         The  authorized  capital stock of URS consists of 20,000,000  shares of
URS  Common  Stock,  $0.01 par  value per  share,  and  1,000,000  shares of URS
Preferred Stock,  $1.00 par value per share. As of September 5, 1997, there were
10,594,025 shares of URS Common Stock  outstanding and no outstanding  shares of
URS  Preferred  Stock.  Holders of URS Common Stock are entitled to one vote for
each share held with respect to all matters  submitted for  consideration by the
URS  stockholders.  The  foregoing  summary  is  qualified  in its  entirety  by
reference to URS's Amended and Restated  Certificate of Incorporation,  which is
filed as an exhibit to the Registration  Statement of which this Prospectus is a
part.

         URS Common  Stock.  The holders of URS Common Stock are entitled to one
vote for each share  held of record on all  matters  submitted  to a vote of the
stockholders.  The  holders of URS Common  Stock are not  entitled  to  cumulate
voting rights with respect to the election of directors,  and as a  consequence,
minority  stockholders will not be able to elect directors on the basis of their
votes  alone.  Subject  to  preferences  that  may be  applicable  to  any  then
outstanding shares of URS Preferred Stock,


                                       30

<PAGE>



holders of URS Common  Stock are entitled to receive  ratably such  dividends as
may be declared by the URS Board of  Directors  out of funds  legally  available
therefor.  See  "Summary  -  Dividend  Policy."  In the event of a  liquidation,
dissolution  or winding up of URS,  holders of the URS Common Stock are entitled
to share ratably in all assets  remaining  after payment of liabilities  and the
liquidation  preference of any then outstanding URS Preferred Stock.  Holders of
URS Common Stock have no preemptive, conversion or other rights to subscribe for
additional securities of URS. There are no redemption or sinking fund provisions
applicable to the URS Common Stock.  All outstanding  shares of URS Common Stock
are, and all shares of URS Common Stock to be  outstanding  upon  completion  of
this offering will be, validly issued, fully paid and nonassessable.

         URS Preferred Stock. The Board of Directors has the authority,  without
further  action  by the  stockholders,  to issue up to  1,000,000  shares of URS
Preferred  Stock  in one or  more  series  and to fix the  rights,  preferences,
privileges and  restrictions  thereof,  including  dividend  rights,  conversion
rights,  voting rights, terms of redemption,  liquidation  preferences,  sinking
fund terms and the number of shares  constituting  any series or the designation
of such series, without any further vote or action by stockholders. The issuance
of URS Preferred Stock could adversely affect the voting power of holders of URS
Common Stock and the likelihood that such holders will receive dividend payments
and payments upon  liquidation and could have the effect of delaying,  deferring
or  preventing a change in control of URS.  There are no shares of URS Preferred
Stock  outstanding  and URS has no  present  plan to  issue  any  shares  of URS
Preferred Stock.

Effect on Existing WC Benefit Plans

         Woodward-Clyde Capital Accumulation  (Retirement) Plan; GCH Acquisition
Corp.  Retirement  Program.  Upon the  execution  of the  Merger  Agreement,  WC
suspended any  obligation to contribute  shares of WC Preferred  Stock to, or to
redeem  shares of WC Preferred  Stock from,  the WC  Retirement  Plan during the
period  from the  date of the  Merger  Agreement  to the  Effective  Time of the
Merger.  Further,  WC agreed,  at the option of URS, to either  terminate the WC
Retirement Plan and/or the GCH Acquisition  Corp.  Retirement  Program (the "GCH
Plan") prior to the Effective  Time of the Merger and/or merge the WC Retirement
Plan and the CGH Plan  with and into the URS  401(k)  Retirement  Plan (the "URS
401(k)  Plan") from the  Effective  Time of the  Merger,  and to  eliminate  any
options available to the WC Retirement Plan, the GCH Plan or their  participants
to purchase  employer  securities  with assets held in the WC Retirement Plan or
the GCH Plan from and after the Effective Time of the Merger.  In the event that
either  of these  plans is  terminated,  participants  will  have the  option of
withdrawing  the balance of their accounts,  which  withdrawal will be a taxable
event,  or rolling  such  account  balance  into the URS 401(k)  Plan or another
qualified  plan  (such as an IRA),  which  should  not be taxed.  WC and URS are
currently exploring potential methods of merging the WC Retirement Plan, the GCH
Plan and the URS 401(k) Plan in a  transaction  to be made  effective  some date
after the Effective Date of the Merger.

         WC Bonus  Plan.  The  Merger  Agreement  also  provides  that after the
Effective  Time of the Merger,  URS will  complete an audit of the  consolidated
financial  statements  of WC for the  period  beginning  on  January 1, 1997 and
ending  on the  Closing  Date  (the  "Bonus  Period").  Promptly  following  the
completion of such audit,  URS will pay bonuses to the former employees of WC in
a manner consistent with prior practices,  but prorated for the Bonus Period, as
follows:  the  aggregate  amount of the bonus pool (the "Bonus Pool") will equal
the  "Annualization  Ratio"  multiplied by the greater of either (i) $500,000 or
(ii) 50% of the excess,  if any,  of  Annualized  1997  Profit over  $8,000,000.
"Annualized  1997 Profit" means the quotient of (A) the net income of WC for the
Bonus Period, as reported in the Woodward-Clyde Interim Financial Statements (as
defined in the Merger Agreement), as adjusted (i)


                                       31

<PAGE>



before any  deduction  for taxes (ii) before any deduction for any bonuses to be
paid, (iii) before the addition of any net income  attributable to settlement of
the GeoCon  Litigation  (as  defined in the Merger  Agreement),  (iv) before the
deduction of any litigation expenses attributable to the GeoCon Litigation up to
the amount of the proceeds of any settlement of the GeoCon  Litigation,  and (v)
before  deduction of the fees and expenses of  Oppenheimer  and legal  expenses,
loan  pre-payment  charges  and  other  external  expenses  incurred  by  WC  in
connection  with the  negotiation,  execution and delivery of this Agreement and
consummation  of the  transactions  contemplated  hereby,  divided  by  (B)  the
Annualization  Ratio.  "Annualization  Ratio"  means  the  ratio  determined  by
dividing the number of actual days in the Bonus Period by 365.

         On or before  the  Closing  Date,  WC will  appoint a  committee  of WC
officers  (the  "Allocation  Committee")  which  will  have  responsibility  for
allocating the amounts  available in the Bonus Pool.  The  Allocation  Committee
will  allocate  bonuses among those  individuals  who were employed by WC on the
Effective  Time  of the  Merger  based  upon  its  evaluation  of  the  relative
contributions  of such employees to WC during the Bonus Period,  and in a manner
consistent with the past annual bonus plan allocation practices of WC. The final
bonus allocations  determined by the Allocation Committee will be subject to the
final reasonable approval of the Chief Executive Officer of URS.

Background of the Merger

         From time to time beginning in January 1996, URS and WC management held
informal  discussions  about the  possibility  of a transaction  between the two
companies.

         On March 7,  1996,  Martin  M.  Koffel,  the Chief  Executive  Officer,
President and Chairman of the Board of URS, and Jean-Yves  Perez,  the President
and Chief  Executive  Officer  of WC,  met in  person.  On March 19,  1996,  Mr.
Ainsworth  and Mr. Wilson met in person.  On March 26, 1996,  URS and WC entered
into a  confidentiality  agreement and exchanged  information.  On May 17, 1996,
Kent P.  Ainsworth,  the Executive Vice President,  Chief Financial  Officer and
Secretary of URS, and Robert K. Wilson,  the Executive  Vice President and Chief
Financial Officer of WC, met in person, and Mr. Koffel, Mr. Ainsworth, Mr. Perez
and Mr.  Wilson met in person.  On May 30, 1996,  Mr.  Ainsworth  and Mr. Wilson
again met in person.

         At these meetings,  the executives discussed informally the possibility
of combining  URS and WC but these  informal  discussions  did not result in any
agreement regarding a transaction between the parties.

         On or about January 25, 1997, upon the recommendation of WC management,
WC's Board of Directors  elected to commence a search for  companies  interested
either in acquiring WC or in engaging in a  transaction  which would result in a
substantial infusion of capital into WC. Thereafter,  WC retained Oppenheimer to
assist WC in such search,  prepared and distributed materials describing WC, and
commenced a formal auction process where WC invited  third-party  offers for the
acquisition of WC or for other transactions which would result in such a capital
infusion.

         The capital  search process  implemented  by  Oppenheimer  entailed the
preparation  of  descriptive  and  financial   information  about  WC  that  was
distributed to 71 companies,  consisting of strategic and financial buyers which
indicated an interest in WC and executed a confidentiality agreement,  including
URS.  Subsequently,  seven  companies,  including  URS,  met  with  WC's  senior
management to discuss


                                       32

<PAGE>



investing in,  merging with, or acquiring WC. Final offers were  submitted on or
about June 24, 1997 by several companies.

         On June 10, 1997, Mr. Koffel and Mr. Ainsworth, together with Robert L.
Costello,  an Executive Vice President of URS Greiner Engineering,  Inc., Ronald
L. Ewing,  a Senior Vice  President of URS Greiner  Engineering,  Inc., and Gary
Jandegian,  a Senior Vice  President  of URS,  met at WC's  corporate  office in
Denver with Mr. Perez, Mr. Wilson, Frank S. Waller, the Chairman of the Board of
WC, James R. Miller, the President of Woodward-Clyde International, and James E.
McCarthy,  the President of Woodward-Clyde Federal Services. A representative of
Oppenheimer also attended this meeting.  URS and WC senior management  exchanged
additional  information  at  this  meeting  about  their  respective  companies,
including the 1997 YTD financial  performances  and their strategic  visions for
the future.

         On July 17 and 18, 1997, Mr. Koffel,  Mr. Ainsworth and Joseph Masters,
Vice President and General  Counsel of URS, met in San Francisco with Mr. Perez,
Mr.  Wilson and Mr.  Waller.  Representatives  of  Oppenheimer  and Smith Barney
attended  the  meeting  on July 17,  1997  and  outside  counsel  for URS and WC
attended both meetings.  Discussions  were held  concerning the form of a merger
agreement and the manner in which the operations and  administrations of the two
companies   might  be   combined.   From  July  22   through   August  8,  1997,
representatives  of URS  visited  numerous  WC offices in the United  States and
abroad to conduct  due  diligence  and to explore  the  potential  benefits of a
combination of the two companies.

         WC management  organized a meeting in Denver on August 12-13, 1997 with
about 40 senior WC  employee  stockholders  and  managers to discuss the various
proposals  resulting  from the search for a strategic  partner.  The  discussion
involved an analysis of the various proposals.  On August 14, 1997, the WC Board
of Directors evaluated the various proposals and voted unanimously to accept the
proposal submitted by URS.

         On August 13, 1997, the Merger  Agreement was approved by the Boards of
Directors  of URS and  Acquisition  Corp.  and on August  14,  1997,  the Merger
Agreement was approved by the Board of Directors of WC. The Merger Agreement was
executed on August 18, 1997. In anticipation of possibly reaching agreement with
WC, URS had  informally  discussed  financing  with  Wells  Fargo and with Wells
Fargo's counsel in August 1997.  These  discussions  ultimately  resulted in the
execution on September  12, 1997 of the  Commitment  Letter (as defined below in
"The Merger Financing of the Merger").

Opinion of URS Financial Advisor

         Smith  Barney was  retained by URS to act as its  financial  advisor in
connection with the proposed  Merger.  In connection with such  engagement,  URS
requested  that Smith Barney  evaluate the fairness,  from a financial  point of
view, to URS of the consideration to be paid by URS in the Merger. On August 13,
1997,  at a  meeting  of the  Board of  Directors  of URS held to  evaluate  the
proposed  Merger,  Smith Barney  delivered an oral  opinion  (which  opinion was
subsequently  confirmed by delivery of a written  opinion dated August 18, 1997,
the date of the Merger Agreement) to the Board of Directors of URS to the effect
that,  as of the date of such  opinion  and based  upon and  subject  to certain
matters stated  therein,  the Merger  Consideration  was fair,  from a financial
point of view, to URS.

         In arriving at its opinion,  Smith Barney reviewed the Merger Agreement
and  held  discussions  with  certain  senior  officers,   directors  and  other
representatives  and  advisors  of URS and  certain  senior  officers  and other
representatives  and advisors of WC concerning  the  businesses,  operations and
prospects


                                       33

<PAGE>



of URS and WC. Smith Barney examined  certain  publicly  available  business and
financial  information  relating  to URS  and  certain  business  and  financial
information  relating  to WC as well as certain  financial  forecasts  and other
information  and  data  for URS  and WC  which  were  provided  to or  otherwise
discussed  with  Smith  Barney  by the  respective  managements  of URS  and WC,
including information relating to certain strategic implications and operational
benefits  anticipated  to result  from the Merger.  Smith  Barney  reviewed  the
financial  terms of the Merger as set forth in the Merger  Agreement in relation
to, among other things: current and historical market prices and trading volumes
of URS Common Stock;  the historical and projected  earnings and other operating
data of URS and WC; and the  capitalization  and financial  condition of URS and
WC.  Smith  Barney  also  considered,  to the  extent  publicly  available,  the
financial terms of certain other similar  transactions  recently  effected which
Smith Barney  considered  relevant in evaluating the Merger and analyzed certain
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations Smith Barney considered  relevant
in evaluating those of URS and WC. Smith Barney also evaluated the potential pro
forma financial impact of the Merger on URS. In addition to the foregoing, Smith
Barney  conducted  other analyses and  examinations  and  considered  such other
financial, economic and market criteria which Smith Barney deemed appropriate in
arriving at its opinion.  Smith  Barney  noted that its opinion was  necessarily
based  upon  information  available,  and  financial,  stock  market  and  other
conditions and circumstances  existing and disclosed,  to Smith Barney as of the
date of its opinion.

         In rendering  its opinion,  Smith  Barney  assumed and relied,  without
independent  verification,  upon the accuracy and  completeness of all financial
and other  information and data publicly  available or furnished to or otherwise
reviewed by or discussed with Smith Barney.  With respect to financial forecasts
and other information and data provided to or otherwise reviewed by or discussed
with Smith Barney,  the managements of URS and WC advised Smith Barney that such
forecasts and other information and data were reasonably prepared reflecting the
best currently available  estimates and judgments of the respective  managements
of URS  and WC as to the  future  financial  performance  of URS  and WC and the
strategic  implications and operational  benefits anticipated to result from the
Merger. Smith Barney assumed, with the consent of the Board of Directors of URS,
that the Merger would be treated as a tax-free reorganization for Federal income
tax  purposes.  Smith Barney did not express any opinion as to what the value of
the URS Common Stock actually will be when issued to WC stockholders pursuant to
the Merger or the price at which the URS Common Stock will trade  subsequent  to
the Merger.  Smith Barney did not make and was not provided with an  independent
evaluation or appraisal of the assets or  liabilities  (contingent or otherwise)
of URS or WC nor did Smith Barney make any physical inspection of the properties
or assets of URS or WC.  Smith Barney was not  requested to consider,  and Smith
Barney's opinion does not address, the relative merits of the Merger as compared
to any alternative business strategies that might exist for URS or the effect of
any other transaction in which URS might engage. Although Smith Barney evaluated
the Merger  Consideration  from a financial point of view,  Smith Barney was not
asked to and did not recommend the specific consideration payable in the Merger,
which  was  determined  through   negotiation  between  URS  and  WC.  No  other
limitations   were   imposed  by  URS  on  Smith  Barney  with  respect  to  the
investigations  made or  procedures  followed by Smith Barney in  rendering  its
opinion.

         The full text of the written  opinion of Smith  Barney dated August 18,
1997, which sets forth the assumptions made,  matters considered and limitations
on the review  undertaken,  is attached  hereto as Appendix B and should be read
carefully in its entirety.  The opinion of Smith Barney is directed to the Board
of Directors of URS and relates only to the fairness of the Merger Consideration
from a financial  point of view to URS, does not address any other aspect of the
Merger or related  transactions and does not constitute a recommendation  to any
stockholder  as to how such  stockholder  should  vote at the URS  Meeting.  The
summary of the opinion of Smith


                                       34

Barney set forth in this Prospectus is qualified in its entirety by reference to
the full text of such opinion.

         In preparing its opinion, Smith Barney performed a variety of financial
and comparative analyses, including those described below. The following summary
of these analyses does not purport to be a complete  description of the analyses
underlying  Smith Barney's  opinion.  The preparation of a fairness opinion is a
complex  analytic  process  involving  various  determinations  as to  the  most
appropriate  and relevant  methods of financial  analyses and the application of
those methods to the particular circumstances and, therefore, such an opinion is
not  readily  susceptible  to summary  description.  Accordingly,  Smith  Barney
believes  that its analyses  must be  considered  as a whole and that  selecting
portions of its  analyses  and  factors,  without  considering  all analyses and
factors,  could  create  a  misleading  or  incomplete  view  of  the  processes
underlying  such  analyses  and  opinion.  In its  analyses,  Smith  Barney made
numerous  assumptions  with respect to URS, WC,  industry  performance,  general
business,  economic,  market and financial conditions and other matters, many of
which are beyond the  control of URS and WC.  The  estimates  contained  in such
analyses and the valuation ranges resulting from any particular analysis are not
necessarily  indicative  of actual  values or  predictive  of future  results or
values,  which may be significantly  more or less favorable than those suggested
by such analyses.  In addition,  analyses relating to the value of businesses or
securities  do not  purport to be  appraisals  or to reflect the prices at which
businesses or securities  actually may be sold.  Accordingly,  such analyses and
estimates are  inherently  subject to  substantial  uncertainty.  Smith Barney's
opinion and analyses  were only one of many factors  considered  by the Board of
Directors  of URS in its  evaluation  of the  Merger and should not be viewed as
determinative  of the views of the Board of Directors or  management of URS with
respect to the Merger Consideration or the proposed Merger.

         Selected Company Analysis. Using publicly available information,  Smith
Barney analyzed,  among other things, the market values and trading multiples of
URS and the following  selected publicly traded companies in the engineering and
construction  industry:  CBI  Industries,  Inc.;  Dames  &  Moore,  Inc.;  Fluor
Corporation;  Foster Wheeler  Corporation;  Granite  Construction  Incorporated;
Harding Lawson Associates Group,  Inc.; Jacobs  Engineering Group Inc.; The Shaw
Group Inc.; and Stone & Webster, Inc. (collectively,  the "Selected Companies").
Smith Barney compared market values as a multiple of, among other things, latest
12 months and estimated  calendar  1997 and 1998 net income and adjusted  market
values (equity market value,  plus total debt, less cash) as multiples of latest
12 months revenues,  estimated  calendar 1997 earnings before  interest,  taxes,
depreciation  and  amortization  ("EBITDA") and latest 12 months earnings before
interest and taxes ("EBIT"). All multiples were based on closing stock prices as
of August 6, 1997. Net income estimates for the Selected Companies were based on
estimates of selected  investment banking firms and net income estimates for URS
and WC were based on internal  estimates of the  managements  of URS and WC. The
range of multiples  (excluding outliers) for the Selected Companies of latest 12
months  and  estimated  calendar  1997 and 1998 net  income and latest 12 months
revenues,  estimated  calendar  1997  EBITDA and  latest 12 months  EBIT were as
follows:  (i) latest 12 months and estimated  calendar 1997 and 1998 net income:
12.1x to 37.6x  (with a mean of 20.0x  and a median  of  18.5x),  11.2x to 41.3x
(with a mean of 17.7x and a median of 16.0x) and 10.1x to 17.5x  (with a mean of
13.6x and a median of 13.7x), respectively; (ii) latest 12 months revenues: 0.2x
to 1.0x  (with a mean of 0.5x and a median of 0.5x);  (iii)  estimated  calendar
1997 EBITDA:  4.9x to 10.4x (with a mean of 7.6x and a median of 7.7x); and (iv)
latest  12  months  EBIT:  9.2x to 22.0x  (with a mean of 12.9x  and a median of
11.1x).  Multiples of latest 12 months and estimated  calendar 1997 and 1998 net
income, latest 12 months revenues,  estimated calendar 1997 EBITDA and latest 12
months EBIT of URS were 16.8x, 15.2x, 13.2x, 0.5x, 6.7x and 9.3x,  respectively.
Based on the  closing  stock  price of URS Common  Stock on August 8, 1997,  the
Merger  Consideration  equated  to  implied  multiples  of latest 12 months  and
estimated calendar 1997 and 1998 net income, latest 12


                                       35

<PAGE>



months revenues,  latest 12 months and estimated calendar 1997 EBITDA and latest
12 months and estimated calendar 1997 EBIT for WC of 25.4x, 15.5x, 13.3x, 0.34x,
6.7x, 5.3x, 11.0x and 7.7x, respectively.

         Selected Merger and Acquisition  Transactions Analysis.  Using publicly
available  information,  Smith Barney  analyzed  the purchase  price and implied
transaction value multiples paid in selected transactions in the engineering and
consulting   industry,   consisting   of   (acquiror/target):   Fluor   Daniels,
Inc./Groundwater  Technology, Inc.; Washington Construction Group, Inc./Morrison
Knudsen  Corporation;   Emcon   Associates/Organic   Waste  Technologies;   Tyco
International   Ltd./The  Earth  Technology   Corporation   (USA);   URS/Greiner
Engineering,  Inc.; Dames & Moore,  Inc./O'BrienKreitzberg  & Associates,  Inc.;
Earth Technology Corporation  (USA)/HazWaste  Industries,  Incorporated;  Foster
Wheeler  Corp./Enserch  Environmental  Corp.; The Earth  Technology  Corporation
(USA)/Summit  Environmental  Group,  Inc.;  TRC  Companies,   Inc./Environmental
Solutions,  Inc.;  Canonie  Environmental  Services  Corp./Riedel  Environmental
Services,  Inc.; and Heidemij  N.V./Geraghy & Miller,  Inc.  (collectively,  the
"Selected Transactions").  Smith Barney compared purchase prices in the Selected
Transactions  as multiples of, among other things,  latest 12 months net income,
and  transaction  values as multiples of, among other  things,  latest 12 months
revenues,  EBITDA and EBIT.  All  multiples for the Selected  Transactions  were
based on information  available at the time of announcement of the  transaction.
The range of  multiples  for the Selected  Transactions  of latest 12 months net
income,  revenue,  EBITDA  and EBIT were as  follows:  (i)  latest 12 months net
income:  7.7x to 41.2x (with a mean of 20.7x and a median of 18.1x); (ii) latest
12  months  revenue:  0.1x to 1.4x  (with a mean of 0.7x and a median  of 0.7x);
(iii) latest 12 months  EBITDA:  5.4x to 16.7x (with a mean of 9.2x and a median
of 7.2x);  and (iv) latest 12 months  EBIT:  7.7x to 16.4x (with a mean of 11.4x
and a median of 10.3x).  Based on the closing stock price of URS Common Stock on
August 8, 1997, the Merger Consideration  equated to implied multiples of latest
12 months and  estimated  calendar  1997 and 1998 net  income,  latest 12 months
revenues,  latest 12 months and  estimated  calendar  1997  EBITDA and latest 12
months and estimated calender 1997 EBIT for WC of 25.4x,  15.5x,  13.3x,  0.34x,
6.7x, 5.3x, 11.0x and 7.7x, respectively.

         No company,  transaction  or  business  used in the  "Selected  Company
Analysis"  or  "Selected  Merger and  Acquisition  Transactions  Analysis"  as a
comparison  is identical to URS, WC or the Merger.  Accordingly,  an analysis of
the results of the foregoing is not entirely  mathematical;  rather, it involves
complex  considerations  and judgments  concerning  differences in financial and
operating  characteristics  and other factors that could affect the acquisition,
public trading or other values of the Selected Companies,  Selected Transactions
or the  business  segment,  company  or  transaction  to which  they  are  being
compared.

         Discounted Cash Flow Analysis. Smith Barney performed a discounted cash
flow  analysis  of the  projected  free cash flow of WC for  fiscal  years  1997
through  2000,  based  on  internal  estimates  of the  management  of  WC.  The
stand-alone discounted cash flow analysis of WC was determined by (i) adding (x)
the present value of projected free cash flows over the four-year period of 1997
to 2000 and (y) the present value of WC's estimated  terminal value in year 2000
and (ii) subtracting the current net debt of WC. The range of estimated terminal
values for WC at the end of the  four-year  period was  calculated  by  applying
terminal  value  multiples  ranging  from  5.0x to 8.0x to WC's  projected  2000
EBITDA,  representing  WC's estimated value beyond the year 2000. The cash flows
and terminal  values of WC were discounted to present value using discount rates
ranging from 10% to 15%.  Utilizing such terminal  multiples and discount rates,
this  analysis  resulted in an equity  reference  range for WC of  approximately
$81.4 million to $151.0 million,  as compared to the equity value implied by the
Merger  Consideration of approximately $100.0 million based on the closing stock
price of URS Common Stock on August 8, 1997.


                                       36

<PAGE>




         Pro Forma  Merger  Analysis.  Smith Barney  analyzed  certain pro forma
effects resulting from the Merger, including,  among other things, the impact of
the Merger on the projected  earnings per share ("EPS") and after-tax  cash flow
of URS for the fiscal years ended 1997 through 1999, based on internal estimates
of the  managements of URS and WC. The results of the pro forma merger  analysis
suggested  that the Merger could be accretive to the EPS and after-tax cash flow
of URS in each of the fiscal years analyzed,  assuming  certain cost savings and
other potential synergies anticipated by the managements of URS and WC to result
from the Merger were  achieved.  The actual  results  achieved  by the  combined
company may vary from projected results and the variations may be material.

         Other Factors and Comparative Analyses. In rendering its opinion, Smith
Barney considered  certain other factors and conducted certain other comparative
analyses,  including,  among  other  things,  a  review  of (i)  historical  and
projected  financial  results of URS and WC; (ii) the history of trading  prices
and volume for URS Common Stock and the  relationship  between  movements in the
URS Common  Stock,  movements in the common stock of  comparable  companies  and
movements  in the S&P 500  Index;  and  (iii)  the pro  forma  ownership  of the
combined company.

         Pursuant to the terms of Smith Barney's  engagement,  URS has agreed to
pay Smith  Barney for its  services in  connection  with the Merger an aggregate
financial  advisory fee of $1.2 million.  URS has also agreed to reimburse Smith
Barney for reasonable travel and other out-of-pocket  expenses incurred by Smith
Barney in performing its services, including the reasonable fees and expenses of
its legal counsel,  and to indemnify  Smith Barney and related  persons  against
certain  liabilities,  including  liabilities under the Federal securities laws,
arising out of Smith Barney's engagement.

         Smith Barney has advised URS that, in the ordinary  course of business,
Smith Barney and its affiliates may actively trade or hold the securities of URS
for their own account or for the account of customers and,  accordingly,  may at
any time hold a long or short position in such  securities.  In addition,  Smith
Barney and its affiliates  (including  Travelers  Group Inc. and its affiliates)
may maintain relationships with URS and WC.

         Smith Barney is an internationally  recognized  investment banking firm
and was  selected by URS based on its  experience  and  expertise.  Smith Barney
regularly  engages  in the  valuation  of  businesses  and their  securities  in
connection with mergers and acquisitions, negotiated underwritings,  competitive
bids,  secondary  distributions  of  listed  and  unlisted  securities,  private
placements and valuations for estate, corporate and other purposes.

Reasons for the Merger; Recommendation of the Board of Directors of URS

         The URS Board of Directors  believes that the combination of URS and WC
will benefit URS's  stockholders.  The reasons for the URS Board authorizing the
Merger include, but are not limited to, the following:

         1.  Consolidation  that is  occurring  within the  industry  with other
public and private  companies.  The increased size of the combined  organization
after the  Merger has been  consummated  will help URS  maintain  a  competitive
advantage in the marketplace and pursue larger, more comprehensive  projects and
client  relationships.  The combined revenue of the two companies will place URS
in the top echelon of the industry.

         2.  The  Merger  helps  URS  achieve  strategic  objectives  previously
established  independently  by the  two  companies.  These  objectives  include:
increased revenues, broader geographic coverage both

domestically and  internationally  and expansion into markets that the companies
on their own would find difficult to accomplish without the Merger.

         3. The combination will result in administrative  efficiencies and cost
savings by consolidating certain overlapping expenses.

The URS  Board  of  Directors  considered  the  above  factors  in  light of its
knowledge of the business,  the industry in general and information  provided by
URS management and its financial  advisor,  Smith Barney.  In view of the number
and  complexity of factors  considered,  the URS Board did not assign a relative
weight to any of the factors considered.

         The URS Board of Directors  believes  that the Merger is fair to and in
the  best  interests  of URS and its  stockholders.  Accordingly,  the  Board of
Directors of URS has  unanimously  approved the Merger  Agreement and recommends
that the  holders  of URS  Common  Stock  vote FOR the  approval  of the  Merger
Agreement.

WC Financial Advisor

         WC retained  Oppenheimer to act as its financial  advisor and to render
its  opinion to WC's Board of  Directors  as to the  fairness,  from a financial
point of view, to WC's current holders of Common Stock, of the consideration for
WC Common Stock provided in the Merger Agreement.  WC selected Oppenheimer based
on its  qualifications,  expertise and  experience.  Oppenheimer is a nationally
recognized firm, and as part of its investment banking business,  Oppenheimer is
regularly  engaged in valuations of businesses and securities in connection with
mergers and acquisitions,  underwritings, secondary distributions of securities,
private placements and valuations for other purposes.

         The Merger Agreement  provides that, among other things, (i) WC will be
merged  with  and  into a  wholly-owned  subsidiary  of URS  (which  will be the
Surviving  Corporation and which will be renamed  Woodward-Clyde  Group,  Inc.),
(ii) each issued and outstanding share of WC Common Stock will be converted into
the right to receive the  Applicable  Common  Multiple (as defined in the Merger
Agreement)  of URS Common Stock and the  Applicable  Common Cash  Component  (as
defined in the Merger Agreement) and (iii) the issued and outstanding  shares of
WC Preferred Stock will be converted into the right to receive $8,306,130 in the
aggregate in cash. On August 14, 1997,  Oppenheimer  made a presentation  to the
Board of Directors of WC stating that, as of August 14, 1997, based on the terms
of the consideration to be received by the current holders of WC Common Stock as
stated in the draft  Agreement  and Plan of Merger  dated as of August 13,  1997
(the "Draft Merger Agreement"),  and additional assumptions made regarding terms
remaining undefined in such draft, such consideration was fair, from a financial
point of view,  to the  current  holders of WC Common  Stock  (the "WC  Fairness
Opinion").  The final  terms as stated in the  Merger  Agreement  do not  differ
materially  from the terms as stated in the Draft  Merger  Agreement  upon which
Oppenheimer  relied,  and  Oppenheimer  subsequently  delivered  its  written WC
Fairness  Opinion dated August 18, 1997 confirming the oral WC Fairness  Opinion
given to the Board of Directors of WC on August 14, 1997.

         The full text of the WC  Fairness  Opinion,  which sets  forth  certain
assumptions made, certain procedures  followed and certain matters considered by
Oppenheimer,  is attached as Appendix C to this Prospectus.  As set forth in the
WC Fairness  Opinion,  Oppenheimer  relied upon and  assumed  the  accuracy  and
completeness of all of the financial and other information  available to it from
public   sources  and   provided   to  it  by  WC,  URS  and  their   respective
representatives. Representatives of each of WC and URS provided Oppenheimer with
its respective financial forecasts. With respect to the financial forecasts


                                       38

<PAGE>



and other data concerning WC and URS reviewed by Oppenheimer, the managements of
each of WC and URS, respectively,  advised it that such forecasts and other data
had been reasonably  prepared on bases reflecting their best currently available
estimates  and judgment as to the future  financial  performance  of WC and URS,
respectively.

         In arriving at its opinion,  Oppenheimer  neither made nor obtained any
independent evaluation or appraisal of the assets or liabilities  (contingent or
otherwise)  of WC or URS,  nor was it  furnished  with any such  evaluations  or
appraisals.  Oppenheimer also assumed,  without  independent  verification,  the
accuracy  of the  advice and  conclusions  of the  parties'  legal  counsel  and
accountants  with  respect to tax and  accounting  matters,  including,  without
limitation, the intention to qualify the Merger as a tax-free reorganization for
Federal income tax purposes and the accounting of the Merger as a purchase.  The
WC  Fairness  Opinion  was  necessarily   based  on  information   available  to
Oppenheimer and the general economic,  financial and stock market conditions and
circumstances as they existed and could be evaluated by Oppenheimer as of August
14, 1997.  Oppenheimer  conducted an extensive  process of  contacting  numerous
third parties to solicit indications of interest in acquiring all or any part of
WC or engaging in a transaction which would result in a substantial  infusion of
capital into WC. No limitations  were imposed by WC on Oppenheimer  with respect
to the investigations made or procedures followed by Oppenheimer.

         The  summary  of the  written  WC  Fairness  Opinion  set forth in this
Prospectus  is  qualified  in its  entirety by reference to the full text of the
opinion which is attached as Appendix C hereto.  WC  stockholders  are urged to,
and should, read this opinion carefully in its entirety in conjunction with this
Prospectus for the assumptions made, matters considered and limits of the review
by Oppenheimer. The WC Fairness Opinion is directed only to the fairness, from a
financial  point of view,  to the  current  holders  of WC  Common  Stock of the
consideration  for WC Common Stock provided in the Merger Agreement and does not
address  any other  aspect  of the  Merger.  The WC  Fairness  Opinion  does not
constitute  a  recommendation  to WC  stockholders  as to how such  stockholders
should vote with respect to whether they should approve the Merger.

         In rendering the fairness opinion, Oppenheimer: (i) reviewed the Merger
Agreement;  (ii)  reviewed the  historical  financial  statements  and financial
projections and other information prepared by the representatives of WC and URS;
(iii) reviewed publicly available  information for WC and URS,  including,  with
respect  to URS,  periodic  and other  reports  filed  with the  Securities  and
Exchange  Commission;  (iv)  reviewed  the  reported  market  prices and trading
volumes for URS' Common Stock; (v) held  discussions with the senior  management
and  representatives  of each of WC and URS concerning  WC's and URS' historical
and current  operations,  financial  condition and prospects;  and (vi) reviewed
such other  documents and financial,  economic and market criteria and made such
other investigations as it deemed appropriate for the purposes of such opinion.

Valuation of WC

         Oppenheimer  performed  five  primary  valuation  analyses of WC: (i) a
Comparable  Company  Analysis,  which  consisted  of reviewing  and  considering
certain  financial and stock market data for certain  publicly traded  companies
engaged in engineering  and consulting or otherwise  deemed by Oppenheimer to be
similar to WC; (ii) a Comparable Mergers and Acquisitions  Transaction  Analysis
which  consisted  of reviewing  certain  financial  data of selected  comparable
acquisitions  involving  companies  engaged in  engineering  and  consulting  or
otherwise  deemed by  Oppenheimer  to be similar to WC; (iii) a Discounted  Cash
Flow Analysis;  (iv) a Contribution  Analysis; and (v) an EPS Dilution Analysis.
Each of the Comparable  Company Analysis and Comparable Mergers and Acquisitions
Transaction Analysis was


                                       39

<PAGE>



applied  to the  most  recent  twelve  months  ended  June  30,  1997 and to the
projected  financial  results of WC for the fiscal years ended December 31, 1997
and 1998,  and the  Discounted  Cash Flow  Analysis was applied to the projected
financial  results of WC for the fiscal  years ended  December  31, 1998 through
2002, to determine a range of implied equity values for WC.

         In establishing  the range of values  resulting from the application of
each  of  the  analyses,  Oppenheimer  made  qualitative  judgments  as  to  the
meaningfulness of the valuation measurements.  The judgments were based upon the
number and similarity of comparable  companies and transactions,  as well as the
predictability  and  volatility of future  earnings when  assessing the relative
significance of the Discounted Cash Flow Analysis. The relative  appropriateness
of  certain  other  valuation  measurements,  such  as  operating  cash  flow or
price/earnings  multiples, as used generally for comparative purposes, were also
taken into account in making such judgments.

         Comparable Company Analysis.  Oppenheimer  compared WC to the following
nineteen  companies engaged in engineering and consulting or otherwise deemed by
Oppenheimer to be similar to WC (the "Comparable  Companies") which are publicly
traded: ATC Group Services Inc., Air & Water Technologies  Corporation,  Michael
Baker Corporation, Dames & Moore, Inc., EA Engineering,  Science and Technology,
Inc., Ecology and Environment,  Inc., EMCON, GZA Geoenvironmental  Technologies,
Inc.,  Harding  Lawson  Associates  Group,  Inc.,   Heidemij  N.V.,  ICF  Kaiser
International,  Inc., International  Technology Corporation,  Jacobs Engineering
Group  Inc.,  OHM  Corporation,  Roy F.  Weston,  Inc.,  Tetra Tech,  Inc.,  TRC
Companies,  Inc.,  Versar,  Inc.  and WS Atkins plc.  Using  publicly  available
information,  Oppenheimer  analyzed,  among other things,  the market values and
certain  financial  criteria for the Comparable  Companies  including  their (i)
revenue,  (ii) earnings before  interest,  taxes,  depreciation and amortization
("EBITDA"),  (iii) earnings  before  interest and taxes  ("EBIT"),  and (iv) net
income,  in each  case  for the most  recent  twelve  month  periods  for  which
financial data were available and, on an estimated  basis,  for the fiscal years
ended 1997 and 1998.  Oppenheimer  excluded certain statistics that it deemed to
be not representative  for the Comparable  Companies as a group. For each of the
multiples of revenue,  EBITDA,  EBIT and net income,  Oppenheimer took the High,
Low and Average (each as defined below) for the Comparable Companies and applied
these  multiples  to the most recent  twelve  months ended June 30, 1997 and for
December 31, 1997 and 1998 projected operating results of WC. For these purposes
the "High" was  calculated as the average of the upper quartile  multiples,  the
"Low" was  calculated as the average of the lower  quartile  multiples,  and the
"Average" was  calculated as a straight  average of all  multiples,  each of the
above  calculations  excluding  those  multiples  deemed  to be not  meaningful.
Although  Oppenheimer  calculated implied equity values using revenue multiples,
it did not deem the results of these calculations to be relevant. The Comparable
Company  Analysis  resulted in implied equity values  (excluding  implied equity
values  based on  revenue  multiples)  for WC which  ranged  from a Low of $32.7
million to a High of $125.6 million. In addition,  Oppenheimer took the range of
Average  implied  equity  values,  for the same  periods,  resulting  in Average
implied  equity  values  (excluding  implied  equity  values  based  on  revenue
multiples) of $62.9 million to $95.4 million.  Although  Oppenheimer  considered
the High and Low implied equity values,  it deemed the range of Average  implied
equity values to be a better measure of WC's value.

         Comparable  Mergers  and  Acquisitions   Transaction  Analysis.   Using
publicly available  information,  Oppenheimer analyzed the consideration paid in
selected  merger  and  acquisition  transactions  (the  "Comparable  Merger  and
Acquisition  Transactions")  involving  companies  engaged  in  engineering  and
consulting or otherwise  deemed by Oppenheimer to be similar to WC.  Oppenheimer
examined  the  following  thirty  transactions  involving  companies  engaged in
engineering  and consulting or otherwise  deemed by Oppenheimer to be similar to
WC over the past four years  (acquiror/target):  Geraghty & Miller,  Inc./Acurex
Environmental  Corporation;  Rust  International  Inc./JRP  Asia Pacific  Group;
Pacific

EMCON/Organic Waste Technologies, Inc.; ATC Environmental, Inc./American Testing
& Engineering  Corporation - Certain Assets; and Carlyle Group  LP/International
Technology   Corporation.   Oppenheimer   calculated   the   multiples   of  the
consideration  paid in relation to the acquired  companies'  most recent  twelve
months  ending prior to the date of the  announcement  of the  acquisition,  for
revenue,  EBITDA,  EBIT  and  net  income.  Similar  to the  Comparable  Company
Analysis, Oppenheimer took the High and Low multiples, respectively, and did not
deem  the  implied  equity  values  calculated  using  revenue  multiples  to be
relevant.  Oppenheimer  then applied these  multiples to WC's most recent twelve
months  operating  results ended June 30, 1997, which resulted in implied equity
values (excluding implied equity values based on revenue multiples) for WC which
ranged from a Low of $30.1  million to a High of $120.4  million.  In  addition,
Oppenheimer took the range of Average implied equity values  (excluding  implied
equity  values based on revenue  multiples),  for the same period,  resulting in
Average implied equity values (excluding  implied equity values based on revenue
multiples) of $60.6 million to $89.3 million. Oppenheimer also took the range of
Average implied equity values based on the projected  operating  results for the
years ended  December 31, 1997 and 1998 (although  Oppenheimer  did not consider
the 1997 and 1998  periods to be as  relevant  because  forward  multiples  were
unavailable)  in addition to the most recent  twelve months ended June 30, 1997.
This resulted in Average implied equity values (excluding  implied equity values
based on revenue  multiples)  of $60.6  million to $116.5  million.  In order to
apply the analyses to 1997 and 1998 data,  Oppenheimer  developed  multiples for
1997 and 1998 by discounting  the most recent twelve month multiples in order to
estimate the future value of such multiples.

         Discounted Cash Flow Analysis.  Oppenheimer performed a Discounted Cash
Flow Analysis of the projected  after-tax  cash flows of WC for the fiscal years
ending  December  31,  1998  through  2002,  based on  forecasts  and other data
provided  by the  management  of WC.  This  analysis  consisted  of  adding  the
discounted  present  value of the  projected  future  cash flows from WC and the
discounted present value of the terminal value of WC at the end of the reference
period.  For purposes of such analysis,  Oppenheimer used discount rates of 10%,
12% and 14%.  Oppenheimer  then  calculated  the terminal value by applying EBIT
multiples  of 6x, 8x and 10x to WC's  projected  EBIT for the fiscal year ending
December 31, 2002. These multiples are generally  consistent with the Comparable
Companies in the industry. The Discounted Cash Flow Analysis resulted in implied
equity values for WC ranging from $54.0 million to $121.8 million.



                                       41

<PAGE>



         Contribution  Analysis.  Oppenheimer  analyzed  WC's and URS'  relative
percentage  contribution  to the pro forma  operating  results for the Surviving
Corporation  resulting  from the Merger with respect to revenue,  EBITDA,  EBIT,
pre-tax income, net income,  total assets and book value. Such analysis was made
for WC's  fiscal  years  ending  December  31, 1997 and 1998 and for URS' fiscal
years ending October 31, 1997 and 1998, based upon projected  operating results.
Oppenheimer  compared  the  relative  percentage  contributions  of  WC  to  the
Surviving Corporation with the percentage ownership of the Surviving Corporation
that WC's  stockholders  would have  received if they had  received  100% of the
consideration  for the WC Common Stock in URS Common Stock. WC's contribution to
the  Surviving  Corporation's  pro forma  results  for the fiscal  years  ending
December 31, 1997 and 1998 ranged from 37.0% to 44.2%. The percentage  ownership
of the Surviving  Corporation  offered to the  stockholders  of WC assuming that
they had  received  100% of the  consideration  for the WC  Common  Stock in URS
Common Stock is 36.2%.

         EPS Dilution Analysis.  Oppenheimer  performed an analysis to determine
the pro  forma  effect  of the  Merger on WC  stockholders'  earnings  per share
("EPS") for the fiscal years ending  December  31, 1997  through  2002.  For the
purpose of this  analysis,  Oppenheimer  calculated  the EPS  Dilution as if the
holders of WC Common Stock had  received  100% of the  consideration  for the WC
Common Stock in URS Common  Stock.  The  percentage  (dilution)/accretion  of WC
stockholder's  EPS as a result of the Merger  would be 0.62%,  (3.05%) and 1.73%
for 1997, 1998 and 1999, respectively.

Valuation of URS

         In  consideration  of the fact that the Merger  involves the payment of
URS  Common  Stock  to the  stockholders  of WC as  part  of  the  consideration
described in the Merger Agreement for the WC Common Stock, Oppenheimer performed
a valuation of URS. Oppenheimer applied the Comparable  Companies Analysis,  the
Comparable Mergers and Acquisitions Transaction Analysis and the Discounted Cash
Flow Analysis  following  the same  methodologies.  In addition,  since URS is a
public company, Oppenheimer was able to perform a common stock trading analysis.
All such  other  analyses  were  applied to the  results  of URS for  comparable
periods and based on the similarities  between WC and URS,  Oppenheimer used the
same Comparable Companies and Comparable Merger and Acquisition Transactions.

         Oppenheimer  performed a Common Stock Trading History Analysis for URS,
reviewing  current and  historical  market prices and trading data of URS Common
Stock  during the  periods  from  August 8, 1995 to August 8, 1997.  Oppenheimer
noted that during such period, URS Common Stock traded between a High of $15.625
and a Low of  $5.50  per  share.  Oppenheimer  performed  a  Comparable  Company
Analysis using the same Comparable Companies used in the WC Comparable Companies
Analysis  based upon EBITDA,  EBIT and net income  multiples for the  Comparable
Companies,  resulting in implied equity values (excluding  implied equity values
based on revenue multiples) for URS, which ranged from a Low of $64.3 million to
a High of $223.6  million.  In addition,  Oppenheimer  took the range of Average
implied equity values for the same periods,  resulting in Average implied equity
values  (excluding  implied equity values based on revenue  multiples) of $118.3
million to $174.5  million.  Although  Oppenheimer  considered  the High and Low
implied  equity  values,  it deemed the range of Average  implied  equity values
(excluding  implied  equity  values based on revenue  multiples)  to be a better
measure of URS'  value.  The  Comparable  Mergers and  Acquisitions  Transaction
Analysis  compared URS with the Comparable  Merger and Acquisition  Transactions
used in WC's Comparable Mergers and Acquisitions Transaction Analysis, resulting
in implied  equity  values  (excluding  implied  equity  values based on revenue
multiples) for URS, which ranged from a Low of $89.6 million to a High of $274.4
million.  In  addition,  Oppenheimer  took the range of Average  implied  equity
values (excluding implied equity values based on revenue  multiples),  resulting
in Average implied equity values for URS of $152.6


                                       42

million to $191.8 million. Oppenheimer performed a Discounted Cash Flow Analysis
based  on  projections  provided  by the  management  of URS.  Oppenheimer  used
discount  rates of 10%, 12% and 14% for the URS  Discounted  Cash Flow Analysis.
Oppenheimer then calculated the terminal value by applying EBIT multiples of 6x,
8x and 10x to URS'  projected  EBIT for the fiscal year ended  October 31, 2002,
which  resulted in implied  equity  values for URS ranging  from a Low of $131.3
million to a High of $255.5 million.

Valuation Conclusion

         In reviewing the Comparable  Company Analysis,  the Comparable  Mergers
and  Acquisitions  Transaction  Analysis and the  Discounted  Cash Flow Analysis
performed  for WC,  as  well as the  Contribution  and  EPS  Dilution  Analysis,
Oppenheimer placed relatively greater weight on the Comparable Company Analysis.
Oppenheimer noted that in performing these analyses, there existed a significant
number of relevant companies that were available to be analyzed.

         A fairness  opinion  is the  product  of a complex  process  and cannot
necessarily be partially analyzed or readily  summarized.  Examining portions of
the analyses  summarized  above,  without  considering  the analyses as a whole,
could  create  an  incomplete  view of the  processes  underlying  Oppenheimer's
opinion. In arriving at its opinion,  Oppenheimer  considered the results of all
of such analyses as were  relevant.  The analyses  were prepared by  Oppenheimer
solely  for  purposes  of  providing  its  opinion  as to  the  fairness  of the
consideration provided in the Merger Agreement,  from a financial point of view,
to the current  holders of WC Common  Stock.  Analyses  based upon  forecasts of
future results are inherently  subject to substantial  uncertainties and are not
necessarily indicative of actual future results, which may be significantly more
or less  favorable  than  suggested  by such  analyses.  Additionally,  analyses
relating  to the values of  businesses  do not  purport to be  appraisals  or to
reflect  the  prices  at which  businesses  may  actually  be sold or  combined.
Accordingly, Oppenheimer expresses no opinion as to what the value of the shares
of the  Surviving  Corporation  actually  will be when  issued to  holders of WC
Common  Stock  pursuant  to the  Merger or the price at which the  shares of the
Surviving  Corporation will trade subsequent to the Merger.  As described above,
Oppenheimer's  opinion and  presentation  to WC's Board of Directors  was one of
many factors taken into  consideration  by WC's Board of Directors in making its
determination  to  approve  the  Merger  Agreement  and  should not be viewed as
determinative of the views of WC's Board of Directors or management with respect
to the  consideration  for the WC  Common  Stock  or the  proposed  Merger.  The
foregoing summary does not purport to be a complete  description of the analyses
performed by Oppenheimer.

         In connection  with the Merger,  WC entered into an  engagement  letter
with  Oppenheimer,  pursuant  to which WC  retained  Oppenheimer  to  provide  a
fairness opinion. Pursuant to such letter, WC agreed to pay Oppenheimer a fee of
$125,000 for  rendering its opinion at the request of WC's Board of Directors in
connection with the Merger. WC has also agreed to reimburse  Oppenheimer for its
reasonable  out-of-pocket  expenses  and to  indemnify  Oppenheimer  and certain
related  persons  against  certain  potential  liabilities  arising  out  of the
engagement of Oppenheimer,  including  liabilities under the Federal  securities
laws. Oppenheimer was also retained by WC to act as its financial advisor in the
Merger. WC entered into an engagement letter with Oppenheimer pursuant to which,
upon  consummation  of  the  Merger  WC  agreed  to  pay  Oppenheimer  a fee  of
approximately $1.5 million for such services,  as adjusted based on the value of
the consideration received by WC stockholders.

         In the ordinary course of its business,  Oppenheimer may actively trade
the  securities  of URS for its own account or for the accounts of its customers
and,  accordingly,  may at any  time  hold a long  or  short  position  in  such
securities.

Reasons for the Merger; Recommendation
of the Board of Directors of WC

         The WC Board of Directors  believes that the  combination of URS and WC
will benefit WC's  stockholders  by providing a cash payment for WC Common Stock
and a  continuing  interest  in a larger  company.  The reasons for the WC Board
authorizing the Merger include, but are not limited to, the following:

         1. The consideration which URS is paying to WC stockholders is believed
to be fair, from a financial point of view, as  substantiated by the Oppenheimer
Opinion.  In  evaluating  the  offer,  the Board  also  considered  URS's  stock
performance  in  recent  years and the stock  prices  of other  publicly  traded
engineering companies.

         2.  Consolidation  that is  occurring  within the  industry  with other
public and private  companies.  The increased size of the combined  organization
after the  Merger  has been  consummated  will help WC  maintain  a  competitive
advantage in the marketplace and pursue larger, more comprehensive  projects and
client  relationships.  The combined revenue of the two companies will place URS
in the top echelon of the industry.

         3.  The  Merger  helps  WC  achieve  strategic  objectives   previously
established  independently  by the  two  companies.  These  objectives  include:
increased  revenues,  increased  services  offered to clients of the  companies,
broader geographic  coverage both domestically and internationally and expansion
into markets that the companies on their own would find  difficult to accomplish
without the Merger.

         4. The combination will result in administrative  efficiencies and cost
savings by consolidating certain overlapping expenses.

The WC Board of Directors considered the above factors in light of its knowledge
of the  business,  the  industry  in  general  and  information  provided  by WC
management  and its financial  advisor,  Oppenheimer.  In view of the number and
complexity of factors considered,  the WC Board did not assign a relative weight
to any of the factors considered.

         The WC Board of  Directors  believes  that the Merger is fair to and in
the  best  interests  of WC and its  stockholders.  Accordingly,  the  Board  of
Directors of WC has  unanimously  approved the Merger  Agreement and  recommends
that the  holders  of WC  Capital  Stock  vote FOR the  approval  of the  Merger
Agreement and the amendment of the Shareholders' Agreement.

Directors and Executive Officers After the Merger

         After the Effective Time of the Merger,  the URS Board of Directors and
URS  executive  officers  will be the same as the current URS Board of Directors
and URS executive officers,  except that after the Effective Time of the Merger,
Messrs.  Frank S. Waller and Jean-Yves Perez will become executive  officers and
directors of URS, and Robert K. Wilson will become an executive  officer of URS.

Transaction."

Registration and Listing

         URS Common  Stock to be issued in the Merger will be  registered  under
the Securities Act. URS has prepared and filed the  Registration  Statement with
the SEC, and has agreed to prepare and file any other  documents  required to be
filed by URS under the  Securities  Act in connection  with the Merger.  URS has
also agreed to take any action  required to be taken under any applicable  state
securities  or "blue sky" laws in  connection  with the  issuance  of URS Common
Stock in connection with the Merger.

         URS has  filed a listing  application  with each of the NYSE and the PE
covering the shares of URS Common Stock which are issuable upon  consummation of
the Merger and expects such listing applications to be approved.

The Merger Agreement

THE FOLLOWING IS INTENDED MERELY AS A SUMMARY OF CERTAIN TERMS AND PROVISIONS OF
THE MERGER  AGREEMENT.  REFERENCE  IS MADE TO THE MERGER  AGREEMENT  ATTACHED AS
APPENDIX A FOR A COMPLETE STATEMENT OF SUCH TERMS AND PROVISIONS.

         Acquisition Proposals; Limitation on Negotiations; Termination Fee. The
Merger Agreement  provides that WC and its subsidiaries will not, and will cause
their respective officers, directors,  employees, agents and representatives not
to,  directly or indirectly,  encourage,  solicit,  accept,  initiate or conduct
discussions or negotiations  with, provide any information to, or enter into any
agreement with, any corporation,  partnership, limited liability company, person
or other entity or group concerning the acquisition of all or a substantial part
of the  assets,  business  or capital  stock of WC,  whether  through  purchase,
merger,  consolidation,  exchange or any other business combination (each of the
foregoing, an "Acquisition Proposal"). Notwithstanding the foregoing, nothing in
the Merger Agreement  prevents WC and its officers and directors from responding
to and  considering  unsolicited  firm  offers  for any such  transactions  from
persons other than URS if and to the extent that, in the written opinion of WC's
outside  counsel,  failure to do so would be  reasonably  likely to constitute a
violation  of  applicable  law or a  breach  of the  fiduciary  duties  of  WC's
directors to WC's  stockholders.  WC has agreed to provide written notice to URS
immediately  of the terms and other details of any such  unsolicited  inquiry or
proposal relating to an Acquisition Proposal.

         In the event that WC or any of its  officers or  directors  enters into
any  negotiations or discussions for any reason which shall  constitute a breach
of the no-shop  provisions of the Merger Agreement as described in the preceding
paragraph, WC has agreed to reimburse URS immediately for all expenses and costs
incurred by URS in connection with the  transactions  contemplated by the Merger
Agreement up to an aggregate maximum of $500,000. In the event that WC or any of
its officers or directors  enters in to any letter of intent,  understanding  or
other  agreement with a party other than URS relating to the  acquisition of all
or a substantial  part of the assets,  business or capital stock of WC,  whether
through  purchase,  merger,  consolidation,   exchange  or  any  other  business
combination,  either  in  violation  of the  no-shop  provisions  of the  Merger
Agreement or within nine months after  termination  of the Merger  Agreement for
any  reason,  then  immediately  upon  entering  into  such  letter  of  intent,
understanding or other agreement,  WC has agreed to pay to URS a termination fee
(the "Termination Fee") of $3,500,000 dollars,  less the aggregate amount of the
URS expenses and costs  previously  reimbursed  to URS pursuant to the preceding
sentence.  The  Termination Fee will not be payable,  however,  if, prior to the
entry by WC into such letter of intent,  understanding or other  agreement,  URS
has  unilaterally  declined to close the Merger,  or the parties  have agreed to
terminate the Merger Agreement by mutual written consent,


                                       45

<PAGE>



or the Merger  Agreement has been properly  terminated by WC (without any breach
of its obligations  under this Agreement) (a) because a governmental  entity has
issued an  order,  decree  or  ruling  or taken  any  other  action  permanently
restraining,  enjoining  or  otherwise  prohibiting  the Merger and such  order,
decree, ruling or other action shall have become final and nonappealable, (b) if
there  has  been  an  uncured  breach  by URS of  any  material  representation,
warranty,  covenant or other agreement in the Merger Agreement, or (c) if any of
the conditions  set forth in the Merger  Agreement have not been fulfilled on or
prior to the date specified for fulfillment,  or shall have become impossible to
fulfill for reasons  beyond the control of WC. The  foregoing  provisions of the
Merger Agreement may have the effect of discouraging competing offers to acquire
or merge with WC.

         Covenants.  The  Merger  Agreement  provides  that from the date of the
Merger  Agreement  until the earlier of the Effective  Time of the Merger or the
termination of the Merger Agreement,  WC, URS and Acquisition Corp. will perform
the following pre-closing covenants:

                  Pre-Closing Covenants of All Parties. Each party has agreed to
customary  pre-closing  covenants,  including:  (1) advising  the other  parties
promptly  of any event that would make any  representation  or  warranty of such
party untrue or inaccurate in any material  respect;  (2) using its best efforts
to  obtain  any  required  regulatory  approvals;   (3)  keeping  all  nonpublic
information of the other parties confidential; and (4) using its best efforts to
do all things necessary to consummate the Merger.

                  Pre-Closing  Covenants  of WC.  WC  has  agreed  to  customary
pre-closing  covenants  affecting  WC  and  its  subsidiaries,   including:  (1)
conducting  its  business  in  the  usual,   regular  and  ordinary   course  in
substantially  the same manner as  conducted in the past,  using all  reasonable
efforts to preserve intact its present business organizations, keeping available
the  services  of  its  present  officers  and  employees,  and  preserving  its
relationships  with  customers  and  suppliers;  (2) not declaring or paying any
dividends  or other  capital  distributions  on its  capital  stock,  splitting,
combining  or  reclassifying  its  capital  stock or  issuing  or  repurchasing,
redeeming or acquiring its capital stock; (3) not issuing, delivering or selling
shares of its capital stock or any securities  convertible into such shares,  or
any rights, warrants, calls, subscriptions or options to acquire any such shares
or convertible securities;  (4) not amending its certificate of incorporation or
bylaws;  (5) not acquiring,  or agreeing to acquire by merging or  consolidating
with, or by purchasing a substantial  equity  interest in all or any substantial
portion  of  the  assets  of,  or by  any  other  manner,  any  business  or any
corporation, partnership, association or other business organization or division
thereof;  (6) other  than in the  ordinary  course  of  business,  not  selling,
leasing,  licensing,  encumbering or otherwise  disposing of any of its material
assets;  (7) not  adopting or amending  in any  material  respect any WC Plan or
paying any pension or retirement  allowance not required by any existing WC Plan
and not entering into any employment  contracts,  paying any special  bonuses or
special  remuneration  to officers,  directors or employees,  or increasing  the
salaries, wage rates or fringe benefits of certain of its officers or employees;
(8) not paying,  discharging,  settling or satisfying any claims, liabilities or
obligations,  except in the ordinary  course of business or in amounts which are
not material,  individually or in the aggregate, to the business of WC, provided
that WC is not prohibited from settling the litigation  filed on March 13, 1996,
by WC in the Denver  District Court  relating to the  acquisition by WC in April
1995 of Geo-Con and all claims and  counterclaims  relating to or arising out of
such acquisition (collectively,  the "GeoCon Litigation") prior to the Effective
Time of the Merger  provided that such  settlement does not require any payments
by WC or any WC subsidiary to any third party and does not impose any continuing
cost or obligation on WC or any WC subsidiary  (other than terms and  conditions
typical of standard settlement agreements);  (9) using its best efforts to carry
on and  preserve its business and its  relationships  with  clients,  customers,
suppliers, employees and others in substantially the same manner as it has prior
to the date of the Merger Agreement;  and (10) using its best efforts to deliver
to URS,  prior to the date the  preliminary  Prospectus is mailed to the SEC, an
agreement


                                       46

<PAGE>



or agreements,  in form and substance reasonably  satisfactory to URS, signed by
each  officer,  director,  holder of more than 1% of the  outstanding  WC Common
Stock or WC  Preferred  Stock and each  other  person who may be deemed to be an
"affiliate" of WC as defined in the Securities Act (the "Affiliate Agreements"),
providing a "continuity of interest"  representation  in a manner  sufficient to
satisfy the requirements of the Code regarding the tax-free nature of the Merger
and  acknowledging  the  restrictions  on  transfer  of URS  Common  Stock to be
received  by them  pursuant to the Merger  under  Rules 144 and 145  promulgated
under the Securities Act.

                  Pre-Closing  Covenants  of URS.  URS has  agreed to  customary
pre-closing  covenants,  including:  (1)  conducting  its business in the usual,
regular and ordinary course in substantially the same manner as conducted in the
past,  using all  reasonable  efforts to preserve  intact its  present  business
organizations,  keeping  available  the  services  of its present  officers  and
employees,  and preserving its relationships  with customers and suppliers;  (2)
consulting  with the  executive  management  of WC  regarding  certain  material
transaction(s);  and (3) without the prior  approval of WC, prior to the Closing
Date,  not  consummating,  or  entering  into  any  binding  agreement  or other
commitment to consummate, any transaction or series of related transactions that
would  (a)  result  in  the  acquisition  of  assets  or a  business  for  total
consideration  in excess of $50 million or requiring  the issuance of URS Common
Stock in excess of 20% of the shares outstanding at that time; (b) result in the
disposition of assets or any business for total  consideration in excess of $100
million, or (c) otherwise require the prior approval of the stockholders of URS.

         Conditions  Precedent to Consummation of Merger.  The Merger will occur
only if the Merger  Agreement is approved and adopted by the  requisite  vote of
URS Stockholders and WC stockholders. In addition, consummation of the Merger is
subject to the satisfaction of certain other  conditions,  unless waived (to the
extent such waiver is permitted  by law). A failure of any such  condition to be
satisfied, if not waived, could prevent the consummation of the Merger.

                  Conditions  to  Obligations  of WC.  The  obligation  of WC to
consummate the Merger is subject to the  satisfaction  of customary  conditions,
including:  (1) WC has  received an opinion of Bronson,  Bronson & McKinnon  LLP
(or,  if  Bronson,  Bronson & McKinnon  LLP for any reason  does not render such
legal opinion,  a legal opinion of Cooley Godward LLP),  dated as of the Closing
Date, to the effect that the Merger will constitute a reorganization  within the
meaning of Section 368 of the Code (except that if the  aggregate  amount of the
Applicable  Common Cash (as defined in the Merger  Agreement)  component exceeds
50% of the total value of the aggregate  Merger  Consideration  determined as of
the Closing Date,  then this condition  shall be deemed to have been waived with
no further  action on the part of WC), and (2) no event has  occurred  which has
caused a material adverse effect on URS between the date of the Merger Agreement
and the Closing Date.

                  Conditions to  Obligations  of URS and  Acquisition  Corp. The
obligations of URS and Acquisition  Corp. to consummate the Merger is subject to
the satisfaction of customary conditions, including (1) URS has received a legal
opinion of a reputable law firm  (reasonably  acceptable to URS)  experienced in
government  contracts  matters,  reasonably  satisfactory in form and content to
URS, to the effect that the  execution,  delivery and  performance of the Merger
Agreement  and the  consummation  of the Merger do not and will not  contravene,
conflict  with or result in a violation  of, or give any  Governmental  Body (as
defined in the Merger  Agreement)  the right to exercise any remedy or to obtain
any relief under, any Government  Contract (as defined in the Merger  Agreement)
to  which  WC or any WC  subsidiary  is a  party  or  under  which  WC or any WC
subsidiary has any rights or  obligations;  (2) URS has received a legal opinion
of Cooley  Godward LLP,  dated the Closing  Date,  to the effect that the Merger
will constitute a reorganization  within the meaning of Section 368 of the Code;
(3) no event has


                                       47

<PAGE>



occurred  which has caused a material  adverse  effect on WC between the date of
the Merger  Agreement and the Closing Date;  and (4) the conditions set forth in
the Commitment Letter have been satisfied.

Merger.

         Termination.  The Merger Agreement may be terminated at any time before
the Merger  becomes  effective  in the  following  circumstances:  (1) by mutual
written  consent  of URS and WC;  (2) by  either WC or URS if (a) the URS and WC
stockholder  approval is not  obtained,  (b) a  governmental  entity  shall have
issued an  order,  decree  or  ruling  or taken  any  other  action  permanently
restraining,  enjoining  or  otherwise  prohibiting  the Merger and such  order,
decree,  ruling or other action shall have become final and nonappealable or (c)
the Merger has not been  consummated  by December  31, 1997  (provided  that the
terminating  party  is not  then  in  material  breach  of  any  representation,
warranty,  covenant or  agreement  contained in this  Agreement);  (3) by URS if
there has been an uncured breach by WC of any material representation, warranty,
covenant  or  other  agreement  in the  Merger  Agreement;  (4) by URS if WC has
entered   into  any   discussions,   negotiations   or  any  letter  of  intent,
understanding  or  other  agreement  relating  to an  acquisition  of  all  or a
substantial part of the assets, business or capital stock of WC (an "Acquisition
Proposal"); (5) by WC if there has been an uncured breach by URS of any material
representation,  warranty,  covenant or other agreement in the Merger Agreement;
(6) by WC if any of


                                       48

<PAGE>



the conditions  set forth in the Merger  Agreement have not been fulfilled on or
prior to the date specified for fulfillment,  or shall have become impossible to
fulfill  for  reasons  beyond  the  control  of WC; and (7) by URS if any of the
conditions set forth in the Merger Agreement have not been fulfilled on or prior
to the date  specified  for  fulfillment,  or shall have  become  impossible  to
fulfill for reasons beyond the control of URS.

         If the Merger  Agreement is  terminated  by either WC or URS for any of
the aforesaid reasons,  the Merger Agreement will thereupon become void and have
no effect,  and there will be no liability or  obligation on the part of WC, URS
or Acquisition  Corp., or their respective  officers and directors,  except that
(i) the  provisions  of  Section  6.2.3 of the  Merger  Agreement  (relating  to
Acquisition  Proposals and the  Termination  Fee),  the  provisions  relating to
termination and the provisions of any then-existing  confidentiality  agreements
between the parties, will survive any such termination;  and (ii) no party whose
breach of its representations, warranties, covenants or agreements was the basis
of the other party's  termination of the Merger  Agreement will be relieved from
liability for damages occasioned by such breach.

         Waiver and Amendment.  At any time before the Merger becomes effective,
any party to the Merger Agreement may (i) extend the time for the performance of
any of the  obligations  or  other  acts  of the  other  parties  to the  Merger
Agreement,  (ii) waive any  inaccuracies in the  representations  and warranties
contained in the Merger  Agreement,  and (iii) waive  compliance with any of the
agreements,  covenants or conditions for the benefit of such party  contained in
the Merger Agreement.  However,  the Commitment Letter provides that URS may not
agree to any material  amendment to, or waive any of its material  rights under,
the Merger Agreement without the prior written consent of Wells Fargo.

   
         The  terms of the  Merger  Agreement  would  permit  the  waiver of the
condition that the parties receive  opinions from counsel to the effect that the
Merger  will  constitute  a  Reorganization  (see  "Certain  Federal  Income Tax
Consequences" below). However, in the event that the receipt of such opinions is
waived,  the parties have agreed to amend this Prospectus to disclose the waiver
of this  condition  and any risks to URS and WC  stockholders  arising from such
waiver,  and distribute such amended  Prospectus to the  stockholders of URS and
WC and resolicit URS and WC stockholder approval.
    

         The Merger  Agreement  may be amended by the parties by action taken by
their respective Boards of Directors at any time before or after the approval of
the URS and WC stockholders,  but after the respective stockholder approvals, no
amendment  may be made  which  by law  requires  the  further  approval  of such
stockholders  without  obtaining such approval.  The Merger Agreement may not be
amended  except  by an  instrument  in  writing  signed on behalf of each of the
parties.

Accounting Treatment

         The Merger will be treated as a  "purchase"  under  generally  accepted
accounting  principles.  The  acquisition  price will be allocated to the assets
acquired  (including  identifiable  intangible  assets) and liabilities.  To the
extent any excess exists after the allocation,  such excess will be allocated to
goodwill. See "Pro Forma Financial Information."

Certain Federal Income Tax Consequences

   
         The discussion set out below summarizes certain opinions received by WC
from  Bronson,  Bronson & McKinnon  LLP,  counsel to WC, and by URS from  Cooley
Godward LLP, counsel to URS, regarding the material United States Federal income
tax considerations  with respect to the Merger that are generally  applicable to
WC  stockholders,  WC,  URS and  Acquisition  Corp.  (the  "Tax  Opinions"). The
discussion does not deal with all Federal income tax considerations  that may be
relevant to specific WC stockholders in light of their particular circumstances,
such as stockholders that are dealers in securities, foreign persons, tax-exempt
entities or stockholders  that received their WC Capital Stock in a compensatory
transaction.  Furthermore,  no state,  local or foreign tax  considerations  are
addressed.  The discussion is based upon provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), as well as regulations, administrative rulings
and judicial decisions thereunder,  all of which are subject to change (possibly
with retroactive  effect) or to different  interpretations.  ALL WC STOCKHOLDERS
ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX  CONSEQUENCES
TO
    


                                       49

<PAGE>



THEM OF THE MERGER,  INCLUDING THE  APPLICABILITY OF FEDERAL,  STATE,  LOCAL AND
FOREIGN TAX LAWS.

   
         The  Tax  Opinions  are  based  on  certain   assumptions  as  well  as
representations  received from WC, URS and certain stockholders of WC (including
an assumption,  based on representations concerning the "continuity of interest"
requirement  discussed  below) and will be subject to the limitations  discussed
below. The Tax Opinions will not be binding on the IRS nor preclude the IRS from
adopting a contrary  position.  Moreover,  no ruling from the  Internal  Revenue
Service  (the "IRS") has been or will be sought  with  respect to any of the tax
matters discussed herein.


         Subject to the  limitations,  qualifications  and exceptions  described
herein,  counsel  have opined that the Merger will  qualify as a  reorganization
under  Section  368(a)  of the Code and that  the  following  consequences  will
result:
    

                  1.  Stockholders of WC who receive part stock and part cash in
         the Merger  will  recognize  gain in the amount of such cash,  limited,
         however,  by such stockholder's  total gain on the Merger (which is the
         difference  between the fair market  value of the URS Common  Stock and
         cash received by such stockholder in the Merger less such stockholder's
         basis in such  stockholder's  WC Capital Stock exchanged  therefor).  A
         stockholder's  recognized  gain  should be  capital  if such WC Capital
         Stock was held as a capital  asset at the time of the Merger,  provided
         that the payment is neither essentially equivalent to a dividend within
         the meaning of Section 302 of the Code nor has the effect of a dividend
         within the meaning of Section  356(a)(2) of the Code  (collectively,  a
         "Dividend  Equivalent  Transaction").  If a loss,  rather  than a gain,
         results from the  application of the  stockholder's  cost basis for the
         stock surrendered against the total consideration  received,  that loss
         will not be recognized;

                  2. The aggregate tax basis of any URS Common Stock received by
         a WC stockholder in the Merger  (including any fractional  share deemed
         received as described in paragraph 4 below)  generally  should be equal
         to the adjusted  basis of the WC Capital Stock  surrendered in exchange
         therefor,  less  the  cash  received  in  the  Merger,  plus  the  gain
         recognized by such stockholder in the Merger (if any);

                  3. The holding  period (for  capital gain  purposes)  for each
         share of URS Common  Stock  received in the Merger  should  include the
         period  during  which  the share of WC  Capital  Stock  surrendered  in
         exchange  therefor  was held,  provided  that such  share of WC Capital
         Stock was held as a capital asset at the time of the Merger;

                  4. A fractional  share of URS Common Stock not actually issued
         pursuant to the Merger but for which cash is  received in lieu  thereof
         should be treated  as a  fractional  share of URS Common  Stock that is
         issued  in the  Merger  and  then  redeemed  by URS.  A WC  stockholder
         receiving cash in lieu of a fractional share generally should recognize
         gain or loss upon the payment  thereof equal to the difference (if any)
         between such stockholder's basis in the fractional share and the amount
         of cash  received.  Such gain or loss should be a capital  gain or loss
         if, at the time of the Merger,  the  stockholder's  WC Capital Stock is
         held as a capital asset; and


                                       50

<PAGE>




                  5.  A WC  stockholder  who  exercises  appraisal  rights  with
         respect to shares of WC Capital  Stock and  receives a cash payment for
         such shares generally  should  recognize  capital gain or loss (if such
         share was held as a capital  asset at the time of the Merger)  measured
         by the difference between the stockholder's basis in such share and the
         amount of cash  received,  provided that such payment is not a Dividend
         Equivalent  Transaction.  A sale of shares  pursuant  to an exercise of
         appraisal   rights   generally  will  not  be  a  Dividend   Equivalent
         Transaction  if,  as  a  result  of  such  exercise,   the  stockholder
         exercising  appraisal  rights  owns no shares of  capital  stock of URS
         (either actually or constructively within the meaning of Section 318 of
         the Code) immediately after the Merger.

         Under  recently  enacted  legislation,  capital gain  generally will be
subject to a maximum rate of tax of 28% on property  held more than one year but
less than eighteen months and a maximum rate of tax of 20% on property held more
than eighteen months.

         The  foregoing   discussion  is  based  on  the  assumption   that  the
"continuity of interest"  requirement will be satisfied in the Merger.  In order
for this requirement to be met,  stockholders of WC must not, pursuant to a plan
or intent existing at or prior to the Merger, dispose of so much of (i) their WC
Capital Stock in  anticipation  of the Merger,  plus (ii) their WC Capital Stock
exchanged  for cash in the Merger,  plus (iii) the URS Common Stock  received in
the Merger (collectively, "Planned Dispositions") such that the WC stockholders,
as a group,  would no longer  have a  "significant  equity  interest"  in the WC
business being conducted by URS after the Merger. WC stockholders will generally
be regarded as having a  significant  equity  interest as long as the URS Common
Stock received in the Merger (after taking into account  Planned  Dispositions),
in the aggregate, represents a "substantial portion" of the entire consideration
received by the WC  stockholders in the Merger.  This  requirement is frequently
referred to as the  "continuity of interest"  requirement.  If the continuity of
interest  requirement  is not  satisfied,  the Merger  would not be treated as a
tax-free   reorganization.   The  law  is  unclear  as  to  what  constitutes  a
"significant  equity  interest"  or a  "substantial  portion."  The  IRS  ruling
guidelines  require 50% continuity  (although such  guidelines do not purport to
represent  the  applicable  substantive  law).  The case law  appears to be more
liberal,  however,  and  in  one  early  case,  the  Supreme  Court  ruled  that
approximately  40%  continuity  was  sufficient.  It is  possible,  although not
anticipated,  that the cash to be  received  in the Merger  could  become such a
large  percentage  of the total  consideration  that the  continuity of interest
requirement  would  not  be  satisfied.  No  assurance  can  be  made  that  the
"continuity of interest"  requirement will be satisfied.  If such requirement is
not satisfied, the Merger would not be treated as a Reorganization.

         A successful IRS challenge to the  Reorganization  status of the Merger
would result in (i) WC recognizing a corporate  level gain or loss on the deemed
sale of all of its assets equal to the difference between the fair market value,
as of the time of the  Merger,  of the URS Common  Stock and cash  issued in the
Merger and WC's basis in such assets;  and (ii) all WC stockholders  recognizing
gain or loss with respect to each share of WC Capital Stock surrendered equal to
the difference  between the fair market value, as of the time of the Merger,  of
the  URS  Common  Stock  and  cash   received  in  exchange   therefor  and  the
stockholder's  basis in such share of WC Capital  Stock.  In such event,  the WC
stockholder's  aggregate basis in the shares of URS Common Stock received in the
exchange  would  equal  the  fair  market  value  of  such  shares,  and  the WC
stockholder's holding period for such shares would not include the period during
which the shares of WC Capital Stock were held.

Regulatory Approvals

         Under the Merger Agreement,  the obligations of URS, WC and Acquisition
Corp. are conditioned upon the receipt of all required  consents of Governmental
Entities (as defined  therein).  There can be no assurance  that any  applicable
regulatory  authority will approve or take other required action with respect to
the Merger or as to the date of such regulatory approval or other action. WC and
URS are not aware of any  government  approvals  that are  required  in order to
consummate  the Merger except as described  below.  Should any other approval be
required,  WC and URS have  agreed to use their  best  efforts to obtain it. See
"The Merger - The Merger Agreement."

         HSR Act.  The parties'  obligations  to close the Merger are subject to
the conditions that the waiting period  applicable under the HSR Act has expired
and that no action has been  instituted by the DOJ or FTC challenging or seeking
to enjoin  the  consummation  of the  transactions  contemplated  by the  Merger
Agreement. WC and URS have submitted their respective applications under the HSR
Act to the DOJ and FTC and were  notified  of early  termination  of the waiting
period under the HSR Act on September 8, 1997.

         Registration Statement.  The Registration Statement has been filed with
the SEC and been declared effective prior to the mailing of this Prospectus. The
effectiveness of the Merger is conditioned  upon the continued  effectiveness of
the Registration Statement.

         Listing Applications.  URS has filed listing applications with the NYSE
and the PE covering  the shares of URS Common  Stock to be issued in  connection
with the Merger and expects such listing applications to be approved.

         Foreign  Filings.  URS and WC also  expect to make  certain  filings in
foreign jurisdictions which may be required to consummate the Merger.

Rights of Dissenting Stockholders

         URS  Stockholders.  Based  upon the  structure  of the  Merger  and the
existing listing of the outstanding URS Common Stock on the NYSE and the PE, URS
stockholders  will not have any  dissenters'  rights with  respect to the Merger
under the Delaware General Corporation Law.

         WC Stockholders.  Stockholders of WC who have neither voted in favor of
the  Merger or  consented  thereto  in writing  pursuant  to Section  228 of the
Delaware  General  Corporation  Law (the  "Delaware  Law")  are  entitled  to an
appraisal by the Delaware Court of Chancery (the  "Delaware  Court") of the fair
value of their  shares of WC Capital  Stock as set forth in  Section  262 of the
Delaware Law, which section is attached as Appendix D to this Prospectus.

         Under  Section 262 of the Delaware  Law, to assert  appraisal  rights a
stockholder  of WC must  deliver  to WC,  prior to the taking of the vote on the
Merger, a written demand for appraisal of his or


                                       52

<PAGE>



her shares.  A vote against the Merger  (whether in person or by proxy) does not
constitute  a demand for  appraisal.  If the Merger is approved by the  required
vote at the WC Meeting,  the surviving entity in the Merger,  Acquisition Corp.,
is required to notify each WC  stockholder  who has  submitted a timely  written
demand  for  appraisal  and who has not  voted in favor of or  consented  to the
Merger of the  Effective  Date of the  Merger.  This notice must be sent to such
stockholders within ten days after the Effective Date of the Merger.

         Within 120 days after the  Effective  Date of the  Merger,  Acquisition
Corp.,  or any  stockholder  who is entitled  to  appraisal  rights,  may file a
petition in the Delaware Court demanding a determination  of the value of the WC
Capital  Stock  held  by all  WC  stockholders  entitled  to  appraisal  rights.
Notwithstanding  the  foregoing,  at any time within 60 days after the Effective
Date of the Merger,  any WC  stockholder  has the right to  withdraw  his or her
demand for appraisal and to accept the terms offered in the Merger.

         Within  120  days  after  the  Effective  Date  of  the  Merger,  a  WC
stockholder who has complied with Sections 262(a) and (d) of the Delaware Law is
entitled, upon submitting a written request, to receive from Acquisition Corp. a
statement  setting forth the  aggregate  number of WC Capital Stock not voted in
favor of the Merger,  the  aggregate  number of WC Capital Stock with respect to
which  demands for  appraisal  have been  received and the  aggregate  number of
holders of such shares.  Such written  statement  will be mailed by  Acquisition
Corp.  within  10 days  after  its  receipt  of such  written  request  from the
stockholder.

         Upon  the  filing  of  a  petition  in  the  Delaware  Court  by  a  WC
stockholder,  service of a copy of such petition  will be made upon  Acquisition
Corp.,  and Acquisition  Corp. will within 20 days after receipt of such service
file in the office of the  Delaware  Register in Chancery a verified  list which
includes  the names  and  addresses  of all WC  stockholders  who have  demanded
payment for their shares of WC Capital Stock and with whom  agreements as to the
value of their shares have not been reached by Acquisition Corp.

         In the absence of an agreement  between  Acquisition  Corp.  and the WC
stockholder,  the Delaware Court will determine  whether the WC stockholders are
entitled to an  appraisal  and, if so, the  Delaware  Court will  appraise  such
shares.  The fair value of such shares will be determined without any element of
value arising from the  accomplishment  or the  expectation  of the Merger.  The
Delaware Court will also determine  whether a fair rate of interest will be paid
upon the amount determined to be the fair value of such shares.  Payment will be
made by  Acquisition  Corp.  to each  stockholder  who has  participated  in the
appraisal  process upon the surrender to Acquisition  Corp. of the  certificates
representing such stockholder's shares of WC Capital Stock.

Financing of the Merger

         Generally.  To finance  some of the cash  portion of the Merger,  Wells
Fargo signed and delivered to URS a commitment  letter dated as of September 12,
1997 (the "Commitment  Letter"),  which has been accepted by URS. The Commitment
Letter  provides that Wells Fargo will provide URS with the  following  loans to
finance  some of the cash  portion of the Merger and to provide  for the working
capital  needs  of URS  thereafter:  a $40  million  revolving  credit  facility
expiring October 31, 2002 and a $110 million term loan maturing October 31, 2004
(the "URS Loans").  The URS Loans will be secured by guarantees from and pledges
of the stock of certain of URS's and WC's  subsidiaries  and will replace  URS's
current  secured  credit  facility.  It is expected  that the  facility  will be
syndicated to include other lenders.


                                       53

<PAGE>




         Interest Rates. The URS Loans will bear interest based on base rate and
Eurodollar  rate  indexes,  with  variable  spreads  over the  applicable  index
selected by URS based on loan maturity and URS's financial performance.

         Conditions to Initial Funding. Wells Fargo's obligation to fund the URS
Loans will expire on January 31,  1998.  In addition,  although  the  Commitment
Letter has been signed and accepted by URS, Wells Fargo's obligation to fund the
URS Loans is  contingent  upon the execution of  definitive  loan  documents and
certain conditions,  including:  the satisfactory completion of due diligence by
Wells Fargo; URS and WC must meet specified  financial  performance tests; there
must be no material  adverse change in the business of URS or WC from the end of
their most recent  respective  fiscal years until the initial  funding date; all
necessary governmental approvals required for the Merger have been received; all
conditions to the consummation of the Merger have been satisfied;  all necessary
documents and legal  opinions must be delivered;  all fees must be paid to Wells
Fargo;  WC must  have  repaid  in full and  canceled  its  credit  line with its
existing  lender;  and there shall not have occurred any material  disruption in
the financial,  banking or capital  markets that would have an adverse effect on
the loan  syndication  markets for loans  similar to the URS Loans.  Although no
assurance may be made, management believes that all conditions to the funding of
the URS Loans will be satisfied.

Interests of Certain Persons in the Transaction.

         WC has entered into Change-in-Control  Agreements, each dated April 17,
1997, with the following employees:  (i) James R. Miller; (ii) Valorie B. Feher;
(iii)  Robert K.  Wilson;  (iv)  James E.  McCarthy;  and (v)  Frank S.  Waller.
Pursuant to such agreements,  if there is an actual or constructive  termination
(other than a termination for cause) of employment  within two years of a Change
in Control,  the employee is entitled to a lump sum payment  equal to one year's
base  salary and for the one year period  following  such  termination  the same
medical,  life and dental  insurance the employee had immediately  prior to such
termination.  For purposes of such agreements,  a Change of Control includes (1)
shareholder  approval of a merger or consolidation  with any other company;  (2)
the complete  liquidation  or an agreement for the sale or disposition of all or
substantially  all of  WC's  assets;  and  (3) the  acquisition  by any  person,
directly or indirectly, of 30% or more of the combined voting power of WC's then
outstanding  securities.  The Merger will  constitute  a "change in control" for
purposes  of  these  agreements.  Also,  for  purposes  of  such  agreements,  a
constructive  termination shall include: (1) a material change in the employee's
functions, duties or responsibilities;  (2) significant reduction in base salary
(other than an  across-the-board  reduction affecting all executive employees of
WC); (3) a material failure by WC to comply with such agreements;  (4) change in
location of the  employee's  office  which is more than 50 miles from his or her
current  office;  and (5) the  failure  of WC to obtain the  assumption  of such
agreements  by any  successor or assign of WC. The terms and  conditions of such
agreements  shall be in lieu of any severance  benefits that would  otherwise be
due to the employee  under policies of WC or its  subsidiaries.  If any of these
employees is terminated and the provisions of such agreements are not applicable
to such termination, then the employee shall receive the same severance benefits
that he or she  would  otherwise  be  entitled  to  receive  under  WC's  normal
severance policies, which, for example, in the case of either Mr. Wilson or Mr.
Waller, would be 39 weeks of base salary.

         As of August 26, 1997, the directors and executive  officers of WC as a
group held 242,598  shares of WC Common Stock.  In  connection  with the Merger,
each of these  individuals  will receive URS Common Stock  transferred as Merger
Consideration. See "Principal WC Stockholders" below.

         URS has  held  discussions  with  selected  members  of WC  management,
including Messrs. Perez, Waller and Wilson,  regarding their status as employees
following the Effective Time of the Merger and the  possibility of entering into
employment and related agreements in this regard. However, as of the


                                       54

<PAGE>



date of this  Prospectus,  no  specific  terms  have been  agreed to and no such
agreements have been finalized.

Material Contacts between URS and WC.

         Other  than  as  discussed  above  with  respect  to  the  negotiations
regarding  the  Merger  Agreement,   there  have  been  no  material  contracts,
arrangements,  understandings,   relationships,  negotiations,  or  transactions
between  URS and WC in the last two fiscal  years or in 1997.  Prior to entering
into the Merger Agreement,  URS and WC have occasionally been contracted to work
on the same  projects,  but have not been  employed  by or for each other in any
material  contract.  Since the Merger Agreement was signed, URS and WC have been
exploring joint business  opportunities  and other means of mutually  supporting
each  other's  business  in  anticipation  of  the  Merger  being   successfully
consummated.

Interests of Named Experts and Counsel.

         Paul J.  Sanner,  now a partner in the law firm of  Bronson,  Bronson &
McKinnon LLP, outside counsel to WC in connection with the Merger,  was employed
by WC for two years as its general counsel. Mr. Sanner purchased WC Common Stock
during his employment in accordance with WC's policies  regarding employee share
ownership.  In accordance  with the terms of the  Shareholders'  Agreement,  the
shares of WC Common  Stock  held by Mr.  Sanner,  which as of August  26,  1997,
equaled 0.67% of the total issued and outstanding shares of WC Common Stock, are
subject to repurchase  by WC. As discussed  below,  the  repurchase of WC Common
Stock from  employee-stockholders  has been  restricted by certain terms of WC's
lending   arrangements.   Mr.   Sanner   is   one   of  a   number   of   former
employeestockholders  of WC on a waiting  list to have their shares of WC Common
Stock repurchased by WC.

                         PRO FORMA FINANCIAL INFORMATION

         The  following   unaudited  pro  forma  combined  condensed   financial
statements  are derived  from the  historical  consolidated  balance  sheets and
related  consolidated  statements  of  operations of URS and WC adjusted to give
effect to the  Merger  using the  purchase  method of  accounting  for  business
combinations.

         The unaudited pro forma combined condensed balance sheet as of July 31,
1997 assumes that the Merger  occurred as of that date.  The unaudited pro forma
combined condensed statement of operations for the fiscal year ended October 31,
1996 assumes that the Merger  occurred as of November 1, 1995. The unaudited pro
forma combined condensed  statement of operations for the nine months ended July
31, 1997  assumes that the Merger  occurred as of November 1, 1995.  In order to
present comparable data for the combining companies,  the pro forma statement of
operations  includes the historical  data for WC for the nine month period ended
June 30, 1997 and for the fiscal year ended December 31, 1996.

         The pro  forma  combined  condensed  balance  sheet  and  statement  of
operations  are provided for  illustrative  purposes  only and should be read in
conjunction  with the  accompanying  notes  thereto,  the  audited  consolidated
financial statement and notes thereto of URS for the year ended October 31, 1996
and the audited financial  statements and notes thereto of WC for the year ended
December 31, 1996 and the related quarterly information for both companies.  The
pro  forma  data is not  necessarily  indicative  of the  operating  results  or
financial position that would have been achieved had the Merger been consummated
at the dates  indicated,  nor is it necessarily  indicative of future  operating
results and financial condition.

                    Notes to the Pro Forma Combined Condensed
                              Financial Statements
 for the Nine Months Ended July 31, 1997 and for the Year Ended October 31, 1996
                                   (Unaudited)

1.       Organization and Basis of Presentation:

         The Merger Agreement described within this Prospectus  contemplates the
merger  of WC into a wholly  owned  subsidiary  of URS.  Based on the  1,964,175
shares of WC Common Stock  issued and  outstanding  on the WC Record  Date,  and
assuming  that the URS  Closing  Price is $14.28  per share (the  average  daily
closing price for such stock on the NYSE over the 20 trading days  preceding the
date the Merger  Agreement  was signed),  each share of WC Common Stock would be
converted  into the right to  receive  $13.59  in cash and  2.317  shares of URS
Common Stock, which would have an indicated  aggregate value of $46.68 per share
of WC Common Stock.

         The pro forma  financial  statements  have been  prepared  based on the
historical  financial  statements of WC, whose fiscal year ends December 31, and
URS,  whose  fiscal year ends  October  31, as  adjusted  for the effects of the
proposed Merger under the purchase method of accounting.  The pro forma combined
condensed  balance sheet as of July 31, 1997 assumes the Merger was  consummated
on that date, and the pro forma combined  condensed  statement of operations for
the fiscal year ended  October 31, 1996 and the nine months  ended July 31, 1997
have been  prepared as if the Merger had been  consummated  on November 1, 1995.
However,  in order to present comparable data for the combining  companies,  the
pro forma  statement of operations  includes the historical  data for WC for the
nine month period ended June 30, 1997 and for the fiscal year ended December 31,
1996.  These  statements  should  be read in  conjunction  with  the  historical
financial statements, and the related notes thereto, included elsewhere herein.

         The  unaudited  pro  forma  financial  statements  are not  necessarily
indicative  of what the  actual  financial  position  would  have been at either
October 31, 1996 or July 31, 1997,  nor of the actual  results of operations for
the year ended October 31, 1996 or the nine months ended July 31, 1997,  had the
Merger  occurred  on the dates  indicated,  nor do they  purport to present  the
future financial position or results of operations of URS and WC.

2.       The Pro Forma Adjustments:

         a. The balance  sheet has been adjusted to reflect the cash to be paid,
debt to be incurred and equity to be issued to acquire WC as if URS had acquired
WC on July 31, 1997 (dollars in thousands).

                  Cash                                           $15,027
                  Term loan - current portion                    (15,368)
                  Term loan - long term portion                   45,341
                  Common Stock                                    65,000
                                                                --------
                                                                $110,000
                                                                ========

         b. Pro forma  adjustments  resulting in the excess  purchase price over
net assets acquired consist of the following (dollars in thousands):

                  Purchase price of WC (net of prepaid
                     loan fees of $4,000)                       $106,000
                  Fair value of net assets acquired              (47,083)
                                                                --------
                  Excess purchase price over net
                     assets acquired                            $ 58,917
                                                                ========



                                       60

<PAGE>



         URS  management  believes  that the amounts  reflected on WC historical
consolidated  balance sheet as to tangible assets and  liabilities  approximates
the fair market values of such assets and  liabilities  and,  accordingly,  such
amounts  have  not  been  adjusted  in  the  accompanying  pro  forma  financial
statements.  The excess purchase price over net assets  acquired  resulting from
the Merger will be amortized on a straight-line basis over 30 years.

         c.  Fees  and  expenses  related  to the  Merger  are  estimated  to be
$10,000,000,  $4,000,000  of which  are  associated  with the  financing  of the
transaction.  The financing fees are being  capitalized  and charged to interest
expense over the seven year term of the loan.  The  remaining  fees and expenses
are being capitalized as goodwill.

         d. The pro forma combined condensed balance sheet reflects the issuance
of approximately  4,552,000 shares of URS Common Stock and cash consideration of

         g. Subsequent to the Merger, WC's operating results will be included in
URS's  consolidated  tax returns,  which results in a pro forma  decrease to the
income tax provision of  $1,595,000  for the nine months ended July 31, 1997 and
$2,070,000 for the year ended October 31, 1996.

         h. The pro forma combined  earnings per share calculation is based upon
the weighted  average  number of URS Common  Stock and Common Stock  equivalents
outstanding,  assuming  the  issuance of  4,552,000  shares of URS Common  Stock
pursuant to the Merger.

3.       Pro Forma Expense Reductions:

         In  management's  opinion,  certain  cost  savings  related  to general
corporate  administration  would have been realized during the pro forma periods
had the Merger been in effect at November 1, 1995;  however, no such adjustments
have been reflected in the foregoing pro forma financial statements.

URS Management's  Discussion and Analysis of Financial  Condition and Results of
Operations

Fiscal 1996 Compared with Fiscal 1995

         Revenues  in fiscal 1996 were  $305.5  million,  or 70% over the amount
reported in fiscal 1995. The growth in revenues is primarily attributable to the
acquisition of Greiner Engineering,  Inc. ("Greiner"),  the results of which are
included  commencing  April 1, 1996,  and to a lesser  extent,  an  increase  in
revenues   derived  from  existing   areas  of  URS's   business,   particularly
transportation  and other  infrastructure  projects in the  Northeast.  Revenues
generated from URS's three largest contracts;  Navy CLEAN, EPA ARCS 9&10 and EPA
ARCS 6, 7 & 8,  decreased  in fiscal 1996 to $30.2  million as compared to $37.1
million in fiscal  1995.  The  decrease  in  revenues  from these  contracts  is
primarily  due to a decrease  in the number of task orders for  hazardous  waste
services on all of the above EPA ARCS contracts.

         Direct  operating  expenses,  which  consist of direct labor and direct
expenses including  subcontractor  costs,  increased $78.3 million, or 72%, over
the amount  reported in fiscal 1995.  The increase is due to the addition of the
direct operating expenses of Greiner and to increases in subcontractor costs and
direct  labor  costs as  well.  Indirect  general  and  administrative  expenses
("IG&A") increased to $102.4 million in fiscal 1996 from $63.2 million in fiscal
1995 which is the result of the  addition of the Greiner  overhead as well as an
increase in business  activity.  Expressed  as a percentage  of  revenues,  IG&A
expenses decreased from 35% in fiscal 1995 to 34% in fiscal 1996. URS attributes
this  decrease to the cost  controls  exercised  by URS.  Net  interest  expense
increased  to $3.9  million in fiscal 1996 from $1.4 million in fiscal 1995 as a
result of increased  borrowings  incurred in connection  with the acquisition of
Greiner.

         With an effective income tax rate of 39% in 1996, URS earned net income
of $7.4  million  while in 1995 net income was $5.1  million  after an effective
income  tax  rate of 20% when  URS had  available  net  operating  loss  ("NOL")
carryforwards which partially offset otherwise taxable income for Federal income
tax purposes. URS earned $0.80 per share on a fully-diluted basis in fiscal 1996
compared to $0.67 per share in fiscal 1995.

         URS's  backlog of signed and funded  contracts  at October 31, 1996 was
$399.2  million as compared to $196.4  million at October 31, 1995. The value of
URS's designations, which are awarded projects for which contracts have not been
signed, was $295.9 million at October 31, 1996, as compared to $194.1 million at
October 31, 1995.

Fiscal 1995 Compared with Fiscal 1994

         Revenues in fiscal 1995 grew to $179.8 million,  or 10% over the amount
reported in fiscal 1994.  The growth in revenues was primarily  attributable  to
increases in revenues  generated from all areas of URS's business,  particularly
transportation  and other  infrastructure  projects in the  Northeast.  Revenues
derived from URS's three largest  contracts:  Navy CLEAN,  EPA ARCS 9&10 and EPA
ARCS  6,7&8,  were $37.1  million in fiscal 1995  compared  to $41.0  million in
fiscal 1994. The decrease in revenues from these  contracts was primarily due to
a decrease in the number of task orders for hazardous waste clean-up services.

         Direct  operating  expenses,  which  consist of direct labor and direct
expenses including  subcontractor costs, increased $6.3 million, or 6%, over the
amount  reported in fiscal 1994. The increase was due to an overall  increase in
URS's business in fiscal 1995 as compared to fiscal 1994. In


                                       63

<PAGE>



fiscal 1995,  IG&A  expenses  increased to $63.2  million from $55.5  million in
fiscal  1994.  However,  expressed as a percentage  of revenues,  IG&A  expenses
increased  from 34% in fiscal 1994 to 35% in fiscal 1995.  URS  attributes  this
increase  to the  overall  increase  in URS's  business.  Net  interest  expense
remained relatively constant at $1.4 million in fiscal 1995.

         URS earned $6.4 million  before income taxes in fiscal 1995 compared to
$4.9 million in fiscal 1994.  While URS had  available NOL  carryforwards  which
partially offset otherwise  taxable income for Federal income tax purposes,  for
state income tax purposes such amounts were not necessarily  available to offset
income subject to tax. Accordingly, URS's effective tax rate for fiscal 1995 was
approximately 20% compared to 9% in 1994.

         Net income  increased  16% to $5.1 million  compared to $4.4 million in
fiscal 1994. URS earned $0.67 per share on a fully-diluted  basis in fiscal 1995
compared to $0.60 per share in fiscal 1994.

         URS's  backlog of signed and funded  contracts  at October 31, 1995 was
$196.4  million as compared to $159.1  million at October 31, 1994. The value of
URS's designations, was $194.1 million at October 31, 1995 as compared to $172.0
million at October 31, 1994.

Third  Quarter  Ended July 31, 1997  Compared With July 31, 1996 and Nine Months
Ended July 31, 1997 Compared With Nine Months Ended July 31, 1996

Third Quarter Ended July 31, 1997 Compared With July 31, 1996

         URS's revenues were  $100,196,000  for the third quarter ended July 31,
1997, an increase of  $10,462,000  or 12% over the amount  reported for the same
period last year. The growth in revenue is attributable to an increase in demand
for URS's services on infrastructure projects. The revenues generated from URS's
three largest indefinite  delivery  contracts,  the Navy CLEAN, EPA ARCS 9 & 10,
and EPA ARCS 6,7 & 8 contracts,  were  $5,261,000 for the quarter ended July 31,
1997, compared to $7,159,000 for the same period last year.

         Direct  operating  expenses for the quarter ended July 31, 1997,  which
consist  of direct  labor and other  direct  expenses,  including  subcontractor
costs,  increased  $5,786,000 an 11% increase  over the amount  reported for the
same period last year.  This increase is due to the  increases in  subcontractor
costs and direct labor costs associated with revenues.

         Indirect,  general and  administrative  expenses for the quarter  ended
July 31, 1997 increased $3,259,000, or 10% over the amount reported for the same
period last year as a result of an increase in business activity.

         URS earned  $5,291,000  before income taxes for the third quarter ended
July 31, 1997  compared  to  $3,432,000  for the same  period  last year.  URS's
effective  income tax rate for the  quarters  ended  July 31,  1997 and 1996 was
approximately 40%.

         URS reported net income of $3,181,000,  or $.28 per share for the third
quarter ended July 31, 1997,  compared with $2,072,000 or $.22 per share for the
same period last year.

         Certain  reclassifications have been made to the allowance for doubtful
accounts and other items in the financial  statements for the three months ended
July 31,  1997 to conform  the  presentation  previously  employed by Greimer to
URS's presentation, with no effect on net income.

Nine months ended July 31, 1997 Compared With July 31, 1996

         URS's  revenues  were  $295,496,000  for the nine months ended July 31,
1997, an increase of  $92,395,000,  or 45% over the amount reported for the same
period last year. The growth in revenues is  attributable  to all areas of URS's
business including  infrastructure  projects involving  transportation  systems,
institutional and commercial  facilities and  environmental  projects as well as
the Greiner acquisition.  Revenues generated from URS's three largest indefinite
delivery  contracts  (Navy  CLEAN,  EPA  ARCS 9 & 10 and EPA ARCS 6, 7 & 8) were
$21,671,000 for the nine months ended July 31, 1997, compared to $21,314,000 for
the same period last year.

         Direct  operating  expenses  for the nine months  ended July 31,  1997,
which consist of direct labor and other direct expenses including  subcontractor
costs, increased $52,335,000, or 43% over the amount reported in the same period
last year.  This  increase  is  attributable  to the  overall  increase in URS's
business  as  compared  to the  same  period  last  year as well as the  Greiner
acquisition. Indirect, general and administrative expenses were $103,789,000 for
the nine months ended July 31, 1997, an increase of $33,007,000, or 47% over the
amount reported for the same period last year. The increase in indirect, general
and  administrative  expenses  is due to an  increase  in  business  activity in
addition to the addition of the Greiner overhead.

         URS earned  $13,014,000  before  income taxes for the nine months ended
July 31, 1997  compared  to  $7,333,000  for the same  period  last year.  URS's
effective  income tax rate for the nine months  ended July 31, 1997 and 1996 was
approximately 40%.

         URS reported net income of $7,834,000  or $.74 per share,  for the nine
months ended July 31, 1997, compared with $4,403,000,  or $.51 per share for the
same period last year.

         URS's  backlog  at July  31,  1997 was  $470,072,000,  as  compared  to
$399,200,000 at October 31, 1996.

         On February 12, 1997,  Wells Fargo exercised the 435,562  warrants held
by Wells Fargo at $4.34 per share,  resulting in the  issuance of an  additional
435,562  shares to Wells Fargo for $1.9 million.  On February 14, 1997,  various
partnerships  managed by Richard C. Blum & Associates,  Inc. ("RCBA")  exercised
1,383,586  warrants held by such entities at $4.34 per share. The exercise price
of  these  warrants  was  paid by a  combination  $2.0  million  of cash and the
cancellation of the $3.0 million amount of debt drawn under URS's line of credit
with  certain  RCBA  entities.  The  exercise  resulted  in the  issuance  of an
additional 1,383,586 shares to the RCBA entities.  These equity transactions are
reflected in URS's financial statements.

         Certain  reclassifications have been made to the allowance for doubtful
accounts and other items in the financial  statements  for the nine months ended
July 31,  1997 to conform  the  presentation  previously  employed by Greimer to
URS's presentation, with no effect on net income.

Income Taxes

         URS currently has a $6.0 million NOL  carryforward  which is limited to
$750,000 per year, pursuant to Section 382 of the Internal Revenue Code, related
to its October 1989 quasi- reorganization.

         URS is a  professional  services  organization  and,  as  such,  is not
capital intensive.  Capital expenditures during fiscal years 1996, 1995 and 1994
were $3.0  million,  $1.6  million and $2.1  million,  respectively  and for the
nine-month  period ended July 31, 1997,  1996 and 1995 were $3.0  million,  $2.3
million and $1.1 million,  respectively.  The expenditures  were principally for
computer-aided  design and general  purpose  computer  equipment to  accommodate
URS's growth.  URS expects fiscal 1997 capital  expenditures to be comparable to
the expenditures in fiscal 1996.

         At July 31, 1997,  URS's senior secured  revolving credit facility with
Wells  Fargo,  provided for  advances of up to $20.0  million.  Also at July 31,
1997, URS had outstanding letters of credit totaling $1.0 million, which reduced
the  amount  available  to URS  under its  revolving  credit  facility  to $19.0
million.

         To finance some of the cash  portion of the Merger,  Wells Fargo signed
and delivered to URS the  Commitment  Letter which has been accepted by URS. The
Commitment  Letter provides that Wells Fargo will provide URS with the following
loans to finance  some of the cash  portion of the Merger and to provide for the
working capital needs of URS thereafter: a $40 million revolving credit facility
expiring five years from the issuance date and a $110 million term loan maturing
six years from the date of the loan.  Such  loans will be secured by  guarantees
from and pledges of the stock of URS's major subsidiaries and will replace URS's
current  secured  credit  facility.  It is expected  that the  facility  will be
syndicated to include other lenders.

         URS believes that its existing financial  resources,  together with its
planned  cash  flow from  operations  and the line of  credit  described  in the
Commitment  Letter,  will provide  sufficient capital to fund its operations and
its capital expenditure needs for the foreseeable future.

         On March 29, 1996, URS acquired Greiner for $78.8 million, comprised of
cash of $69.3 million,  and 1.4 million shares of URS Common Stock. The purchase
was partially financed by $50.0 million of secured term loans payable over seven
years  beginning  October 1996.  The loans bear  interest  based on rate indexes
selected by URS,  with  variable  spreads over the selected  index based on loan
maturity and URS's financial performance.

         The  acquisition  has been  accounted  for by the  purchase  method  of
accounting and the excess of the fair value of the net assets  acquired over the
purchase price has been allocated to goodwill.  The operating results of Greiner
are included in URS's results of operations from the date of purchase.

WC  Management's  Discussion and Analysis of Financial  Condition and Results of
Operations


Fiscal 1996 Compared with Fiscal 1995

         Gross  Revenues  from services in fiscal 1996 were $320.2  million,  3%
greater than in fiscal 1995.  Substantially all of the increase was attributable
to  increases  in  direct  costs  of  outside  services  as a  result  of  using
subcontractors.  Net  revenues  declined  to $209.4  million in fiscal 1996 from
$216.4  million in fiscal  1995.  While net  revenues in Europe were down 11% in
fiscal 1996  reflecting  difficult  market  conditions due to  competition,  net
revenues in  Asia-Pacific  increased to $30.0  million in fiscal 1996 from $21.1
million in fiscal 1995 due to  increased  demand for WC's  services.  Offsetting
this gain was a decline  in North  America  net  revenues  to $170.0  million in
fiscal 1996 from $184.9 million in fiscal 1995.  This decline is attributable to
a  general  decline  in  demand  and  to  delays  in  U.S.  Federal   government
procurements  for  engineering  and  environmental  services  and  to  increased
industry-wide competition.

         Salaries  and benefits in fiscal 1996  declined to $147.7  million from
$150.9 million in fiscal 1995. This decline generally  followed the shift in net
revenues  as they are  directly  related.  General  expenses  declined  to $48.6
million  in fiscal  1996 from $50.7  million in fiscal  1995 as a result of cost
reduction efforts.  Depreciation and amortization and interest expense in fiscal
1996 and fiscal 1995 were consistent from year to year.

         As a result of the decline in net revenues in fiscal 1996 versus fiscal
1995,  income before income taxes decreased to $3.5 million from $5.4 million in
fiscal  1995.  Income taxes in fiscal 1996 were $1.9  million,  or 54% of income
before income taxes, compared with an effective income tax rate of 47% in fiscal
1995.  Rates in both  years  were  substantially  higher  than the U.S.  Federal
statutory rate of 35% due to state and foreign taxes and to non-deductible costs
and expenses for Federal income tax purposes.

         Net income  applicable  to common  shares  declined to $0.5  million in
fiscal 1996 from $1.6 million in fiscal 1995,  or $0.26 per share in fiscal 1996
versus $0.82 per share in fiscal 1995.

         WC's  backlog at December  31,  1996 was $189.0  million as compared to
$162.0 million at December 31, 1995.

Fiscal 1995 Compared with Fiscal 1994

         Gross revenues from services in fiscal 1995 increased to $310.4 million
from $274.9  million in fiscal 1994,  or 13%. Of the increase of $35.5  million,
$26.4 million came from the April 1995  acquisition  of a specialty  contractor,
$4.4 million came from increases in the use of subcontractors  and the remainder
came from an  increased  demand for WC's  services.  Net  revenues  increased to
$216.4  million in fiscal 1995 from  $200.5  million in fiscal  1994,  or 8%, of
which $10.2 million was from the  aforementioned  acquisition  and the remainder
was from increases in demand for WC's services.

         Salaries and benefits  increased to $150.9  million in fiscal 1995 from
$138.5 million in fiscal 1994, or 9%. This increase generally followed shifts in
net  revenues  as they are  directly  related.  General  expenses in fiscal 1995
increased  following  the  increase  in  net  revenues  and as a  result  of the
aforementioned  acquisition.   Depreciation  and  amortization  in  fiscal  1995
increased  to $6.8  million  from $5.6  million in fiscal 1994 due to  increased
capital  expenditures and to the  aforementioned  acquisition.  Interest expense
increased in fiscal 1995 due to additional  borrowings  in  connection  with the
aforementioned acquisition.



                                       69

<PAGE>



         Income before income taxes declined to $5.4 million in fiscal 1995 from
$8.9 million in fiscal 1994. Income taxes in fiscal 1995 were $2.5 million based
on an effective tax rate of 47% compared  with 42% in fiscal 1994.  The increase
in the tax rate is attributable to non-deductible costs and expenses.

         Net income  applicable  to common  shares  declined to $1.6  million in
fiscal 1995 from $3.8 million in fiscal 1994,  or $0.82 per share in fiscal 1995
versus $1.97 per share in fiscal 1994.

</TABLE>


         The decline in WC's working  capital from December 31, 1994 to December
31, 1996 was primarily due to WC  refinancing  long-term debt using funds from a
revolving line of credit. The increase in WC's working capital from December 31,
1996 to June 30, 1997 was due to WC's improved operating results.

         In  September  1996 WC entered  into a $30  million  revolving  line of
credit and a $6 million term loan domestically  with a lender.  In addition,  WC
has international  lines of credit with a total capacity of $2.9 million.  It is
anticipated  that the $30  million  revolving  line of credit and the $6 million
term loan will be fully paid and terminated  following the Effective Time of the
Merger.

         WC is primarily a professional  services  organization and, as such, is
not capital  intensive.  Capital  expenditures for the six months ended June 30,
1997  and the  fiscal  years  ended  December  31,  1996,  1995  and  1996  were
$1,799,000, $3,019,000, $4,609,000 and $5,226,000, respectively.

         WC believes that its existing  financial  resources,  together with its
planned cash flow will provide sufficient capital to find its operations and its
capital expenditure needs for the foreseeable future.

Acquisition

         On April 28,  1995,  WC  purchased  all of the issued  and  outstanding
common stock of GCH Acquisition  Corporation  for $8,150,000,  for which WC paid
cash of $7,146,878  and issued 43,614 shares of its Common Stock with a value of
$1,003,122.  The  transaction  was  accounted  for under the purchase  method of
accounting.  Of the purchase  price,  $5,221,000  was recorded as excess of cost
over net assets  (goodwill)  acquired.  During  1996,  an  additional  amount of
goodwill was recognized in the amount of $3,466,000 net of taxes, as a result of
changes in the estimated profitability of contracts acquired.

         On October  3, 1995,  WC  purchased  all of the issued and  outstanding
stock of Cole Sherman and Associates  Limited ("CSA"),  a Canadian  corporation,
for  $1,429,646.  The transaction was accounted for under the purchase method of
accounting.  During 1996, WC wrote off uncollectible  accounts receivable within
CSA of approximately  $217,000, and recorded this amount as additional excess of
cost over net assets acquired.

Six Months ended June 30, 1997 Compared with Six Months ended June 30, 1996

         Gross  revenues from services in 1997  increased to $161.2 million from
$156.4  million in 1996,  or 3%. Direct costs of outside  services  increased to
$51.3 million,  or 2%. Net revenues increased by $3.6 million,  or 3%, to $109.9
million in 1997 from $106.3 million in 1996,  due primarily to increased  demand
for construction contract services.

         Costs  and  expenses,  comprised  of  salaries  and  benefits,  general
expenses and depreciation and amortization remained consistent at $102.2 million
in 1997 versus $102.8 million in 1996, primarily as a result of cost management.
Interest expense also remained relatively constant in 1997 versus 1996.

         As a result of the foregoing,  income before income taxes  increased to
$6.4 million in 1997 from $2.0 million in 1996.  WC's effective  income tax rate
in 1997 was 47% compared to 48% in 1996.

         Net  income  applicable  to  common  shares  in 1997 was  $2.9  million
compared to $0.5  million in 1996,  or $1.46 per share versus $0.25 per share in
1996.

         WC's backlog at June 30, 1997 was $ 212 million.

Three Months ended June 30, 1997 Compared with Three Months ended June 30, 1996

         Gross  revenues from  services in 1997  increased to $84.6 million from
$79.4  million in 1996,  or 7%.  Direct costs of outside  services  increased to
$27.2  million,  or 3%. Net  revenues  increased by $4.4  million,  8%, to $57.4
million in 1997 from $53.0 million in 1996,  due  primarily to increased  demand
for construction contract services.

         Costs  and  expenses,  comprised  of  salaries  and  benefits,  general
expenses and depreciation and amortization,  increased by $1.5 million, or 2.9%,
from $51.1  million  in 1996 to $52.6  million in 1997.  This  reflected  slower
growth than was experienced in revenues due to cost management. Interest expense
in 1997  decreased to $0.7 million from $0.8 million in 1996,  due to reductions
in debt balances and average interest rate.

         As a result of the foregoing,  income before income taxes  increased to
$4.2 million in 1997 compared to $1.1 million in 1996. WC's effective income tax
rate in 1997 was 47%  compared  to 50% in 1996,  reflecting  differences  in the
effect of state and foreign  taxes and the  non-deductibility  of  expenses  for
Federal income tax purposes.

         Net  income  applicable  to  common  shares  in 1997 was  $1.9  million
compared to $0.2  million in 1996,  or $0.98 per share versus $0.12 per share in
1996.

                           INFORMATION CONCERNING URS

Overview

         URS  offers  a  broad  range  of  planning,   design  and  program  and
construction  management services.  URS serves public and private sector clients
on infrastructure  projects  involving  transportation  systems,  facilities and
environmental  programs.  URS  conducts  its business  through  offices  located
throughout the United States.  URS has  approximately  3,250 employees,  many of
whom hold  advanced  or  technical  degrees  and have  extensive  experience  in
sophisticated  disciplines  applicable to URS's business.  URS believes that its
geographic and technical  diversity allow it to compete for local,  regional and
national projects, and enable it to apply to each project a variety of resources
from its national network.

Services

         URS  provides  professional  services in three major  areas:  planning,
design and  program  and  construction  management  through  URS's 35  principal
offices.  Each of these offices is responsible  for obtaining  local or regional
contracts. This approach allows regional government agencies and private clients
to view  URS's  offices  as local  businesses  with  superior  service  delivery
capabilities.  Because  URS can draw  from its  large  and  diverse  network  of
professional  and  technical  resources,  URS has the  capability  to market and
perform large multi-state projects.

         Planning.  Planning  covers a broad range of  assignments  ranging from
conceptual  design and technical and economic  feasibility  studies to community
involvement  programs.  Planning  services also involve  developing  alternative
concepts  for  project   implementation   and  analyzing  the  impacts  of  each
alternative.  In addition to traditional  engineering and architectural planning
services,  URS has extensive  expertise in a number of highly specialized areas,
including toll facilities,  health care facility renovation,  environmental site
analysis,  water  quality  planning  for urban storm water  management  and site
remediation assignments.

         Design.  URS's  professionals  provide  a broad  range  of  design  and
design-related  services,  including  computerized  mapping,  architectural  and
interior design,  civil, sanitary and geotechnical  engineering,  process design
and seismic  (earthquake)  analysis and design. For each project, URS identifies
the project  requirements and then integrates and coordinates the various design
elements.  The result is a set of contract  documents  that may  include  plans,
specifications  and cost  estimates  that are  used to  build a  project.  These
documents  detail design  characteristics  and set forth for the  contractor the
materials which should be used and the schedule for construction. Other critical
tasks in the design  process may include  value  analysis and the  assessment of
construction and maintenance requirements.

         Program and  Construction  Management.  URS's program and  construction
management   services   include  master   scheduling  of  both  the  design  and
construction  phases,  construction  and life-cycle cost  estimating,  cash flow
analysis, value engineering,  constructability reviews and bid management.  Once
construction  has begun,  URS supervises and  coordinates  the activities of the
construction  contractor.   This  frequently  involves  acting  as  the  owner's
representative for on-site  supervision and inspection of the contractor's work.
In this role,  URS's  objective  is to monitor a  project's  schedule,  cost and
quality.  URS  generally  does  not  take  contractual  responsibility  for  the
contractor's risks and methods, nor for site safety conditions.

Markets

         URS's strategy is to focus on the infrastructure  market which includes
surface and air transportation systems, institutional and commercial facilities,
and environmental  programs  involving  pollution  control,  water resources and
hazardous waste management.

         Surface and Air  Transportation  Systems.  URS's engineers,  designers,
planners and managers  provide  services  for  projects  involving  all types of
transportation systems and networks, such as highways, roadways,


                                       72

<PAGE>



streets, bridges, rapid and mass transit, airports and marine facilities.  These
services  range  from the  design  of  interstate  highways  to  harbor  traffic
simulation  studies  and  may  extend  from  conceptual   planning  through  the
preliminary and final design to  construction  management.  Historically,  URS's
emphasis  in this  market  area has  been on the  design  of new  transportation
systems, but in recent years the rehabilitation of existing systems has become a
major focus.

         Institutional and Commercial  Facilities.  URS provides  architectural,
engineering design, space planning and construction supervision services to this
market area.  Demand for  low-maintenance,  energy efficient  facilities  drives
today's market for commercial and industrial  buildings.  In addition,  there is
increased  pressure to renovate  facilities to meet  changing  needs and current
building standards.

         Pollution Control.  URS's principal services in this market include the
planning  and design of new  wastewater  facilities,  such as sewer  systems and
wastewater treatment plants, and the analysis and expansion of existing systems.
The types of work performed by URS include infiltration/inflow studies, combined
sewer overflow studies,  water quality  facilities  planning projects and design
and construction management services for wastewater treatment plants.

         Water  Resources.  URS's  capabilities  in this market area include the
planning,  design and  program  and  construction  management  of water  supply,
storage,  distribution  and treatment  systems,  as well as work in basin plans,
groundwater supply,  customer rate studies,  urban run-off,  bond issues,  flood
control, water quality analysis and beach erosion control.

         Hazardous  Waste  Management.  In this  market  segment,  URS  conducts
initial site  investigations,  designs  remedial  actions for site  clean-up and
provides  construction  management  services  during site clean-up.  This market
involves identifying and developing measures to effectively dispose of hazardous
and toxic waste at contaminated  sites. URS also provides air quality monitoring
and designs individual facility  modifications required to meet local, state and
Federal air quality standards.  This work requires specialized  knowledge of and
compliance with complex Federal and state regulations, as well as the permitting
and approval processes.  Solid waste management services provided by URS include
facility siting, transfer station design and community-wide master planning.

         Contract   Pricing  and  Terms  of  Engagement.   Under  its  cost-plus
contracts,  URS  charges  clients  negotiated  rates  based on URS's  direct and
indirect  costs.  Labor  costs  and  subcontractor  services  are the  principal
components  of URS's direct costs.  Federal  Acquisition  Regulations  limit the
recovery  of  certain  specified  indirect  costs on  contracts  subject to such
regulations.  In negotiating a cost-plus contract, URS estimates all recoverable
direct and indirect  costs and then adds a profit  component,  which is either a
percentage of total  recoverable costs or a fixed negotiated fee, to arrive at a
total dollar estimate for the project.  URS receives  payment based on the total
actual number of labor hours expended. If the actual total number of labor hours
is lower than  estimated,  the  revenues  from that  project  will be lower than
estimated.  If the actual  labor hours  expended  exceed the initial  negotiated
amount, URS must obtain a contract  modification in order to receive payment for
such  overage.  URS's profit  margin will  increase to the extent URS is able to
reduce actual costs below the  estimates  used to produce the  negotiated  fixed
prices on contracts not covered by Federal Acquisition Regulations;  conversely,
URS's profit  margin will  decrease and URS may realize a loss on the project if
URS does not control costs and exceeds the overall estimates used to produce the
negotiated price. Cost-plus contracts covered by Federal Acquisition Regulations
require an audit of actual costs and provide for upward or downward  adjustments
if actual  recoverable costs differ from billed  recoverable  costs. The Defense
Contract Audit Agency,  auditors for the Department of Defense and other Federal
agencies,  has completed  incurred  cost audits of URS's  Federal  contracts for
fiscal  years  ended   through   October  31,  1988,   resulting  in  immaterial
adjustments.

         Under its fixed-price contracts,  URS receives an agreed sum negotiated
in advance for the specified  scope of work.  Under  fixed-price  contracts,  no
payment  adjustments are made if URS overestimates or under-estimates the number
of labor hours  required to complete  the  project,  unless there is a change of
scope  in the  work to be  performed.  Accordingly,  URS's  profit  margin  will
increase  to the extent the number of labor  hours and other costs are below the
contracted  amounts.  The profit margin will decrease and URS may realize a loss
on the project if the number of labor hours  required and other costs exceed the
estimates.

         For the fiscal year ended October 31, 1996,  the percentage of revenues
attributable  to cost-plus  contracts  was 50.1% and the  percentage of revenues
attributable to fixed-price  contracts was 26.6%. For the nine months ended July
31, 1997, the percentage of revenues attributable to cost-plus contracts was 72%
and the percentage of revenues attributable to fixed-price contracts was 20%.

         Backlog, Project Designations and Indefinite Delivery Contracts.  URS's
contract backlog was $470.1 million at July 31, 1997,  $399.2 million at October
31,  1996,  and $196.4  million at October  31,  1995.  URS's  contract  backlog
consists  of the  amount  billable  at a  particular  point in time  for  future
services under executed funded contracts.  Indefinite delivery contracts,  which
are executed  contracts  requiring the issuance of task orders,  are included in
contract backlog only to the extent the task orders


                                       74

<PAGE>



are actually  issued and funded.  Of the contract  backlog of $470.1  million at
July 31, 1997,  approximately 30%, or $141.0 million, is not reasonably expected
to be filled within the next fiscal year ending October 31, 1997.

         URS has also been  designated  by customers as the recipient of certain
future contracts.  These  "designations"  are projects that have been awarded to
URS but for  which  contracts  have not yet been  executed.  Task  orders  under
executed  indefinite  delivery  contracts which are expected to be issued in the
immediate future are included in designations.  Total contract designations were
estimated to be $454.2  million at July 31, 1997,  $295.9 million at October 31,
1996 and $194.1 million at October 31, 1995. Typically, a significant portion of
designations are converted into signed contracts. However, there is no assurance
this will continue to occur in the future.

<TABLE>

         Indefinite  delivery  contracts are signed contracts  pursuant to which
work is  performed  only when  specific  task  orders are issued by the  client.
Generally these contracts  exceed one year and often indicate a maximum term and
potential value.  Certain indefinite  delivery contracts are for a definite time
period  with  renewal  option  periods  at the  client's  discretion.  While URS
believes  that it will  continue  to get work under these  contracts  over their
entire term,  because of renewals and the  necessity  for issuance of individual
task  orders,  continued  work by URS and the  realization  of  their  potential
maximum values under these  contracts are not assured.  However,  because of the
increasing  frequency with which URS's government and private sector clients use
this contracting  method, URS believes their potential value should be disclosed
along with backlog and  designations  as an indicator of URS's future  business.
When the  client  notifies  URS of the scope and  pricing  of task  orders,  the
estimated  value of such task  orders is added to  designations.  When such task
orders are signed and funded,  their value goes into backlog.  At July 31, 1997,
the potential value of URS's five largest  indefinite  delivery contracts was as
follows:

Competition

         The  engineering  and   architectural   services   industry  is  highly
fragmented and very  competitive.  As a result, in each specific market area URS
competes  with many  engineering  and  consulting  firms,  several  of which are
substantially larger than URS and which possess greater financial resources.  No
firm  currently  dominates  any  significant  portion  of  URS's  market  areas.
Competition  is based on quality of service,  expertise,  price,  reputation and
local presence.  URS believes that it competes favorably with respect to each of
these factors in the market areas it serves.

Employees

         URS has  approximately  3,250 employees,  many of whom hold advanced or
technical  degrees and have  extensive  experience  in a variety of  disciplines
applicable to URS's business.  URS also employs, at various times on a temporary
basis,  up  to  several   hundred   additional   persons  to  meet   contractual
requirements. Thirteen of URS's employees are covered by a collective bargaining
agreement.  URS has never  experienced a strike or work  stoppage.  URS believes
that employee relations are good.

Properties

         URS leases office space in 35 principal locations throughout the United
States.  Most of the leases are written  for a minimum  term of three years with
options  for  renewal,   sublease   rights  and  allowances  for   improvements.
Significant  lease agreements expire at various dates through the year 2005. URS
believes that its current  facilities  are  sufficient  for the operation of its
business  and  that  suitable  additional  space in  various  local  markets  is
available to accommodate any needs that may arise.

Acquisitions

         In  January  1995,  URS  acquired  privately-held  ECD of  Tallahassee,
Florida, an engineering firm specializing in bridge and highway design. In March
1996 URS acquired  publicly-held  Greiner  Engineering,  Inc., an Irving,  Texas
engineering and architectural design services firm ("Greiner").  The acquisition
of Greiner nearly doubled the size of URS, increasing the number of offices from
24 to 35, and the number of employees from approximately  1,300 to approximately
3,000. Following this acquisition,  Greiner became a wholly-owned  subsidiary of
URS. Major efforts have been made to integrate the functions of both  companies.
URS  undertook  to  change  the  name of each  of its  and  Greiner's  operating
subsidiaries to reflect the name "URS Greiner." In addition,  regional divisions
of both  companies  were combined  under common  management  to  facilitate  the
operation of the combined  business and the delivery of services to its clients.
In  July  1997,  URS  acquired  privately-held  WVP  Corporation  of St.  Louis,
Missouri, an engineering, architecture and planning firm with offices in St.
Louis, and Chicago and Decatur, Illinois.

Legal Proceedings

         Various legal  proceedings are pending against URS or its  subsidiaries
alleging breaches of contract or negligence in connection with URS's performance
of professional services. In some actions, damages (including punitive or treble
damages) are sought which substantially  exceed URS's insurance coverage.  Based
upon management's  experience that most legal  proceedings  settle for less than
any claimed  damages,  at this time management does not believe that any of such
proceedings  are likely to result in a judgment  against,  or settlement by, URS
materially  exceeding URS's insurance coverage or have a material adverse effect
on the consolidated financial position and operations of URS.

                            INFORMATION CONCERNING WC

Overview

         Founded  in  1950 as a  soils  consulting  engineering  firm  based  in
Oakland,  CA, by the late 1960's WC had grown to become one of the leading firms
in the field of geotechnical  engineering and applied earth sciences consultancy
in the U.S.  Following the passage of the National  Environmental  Policy Act in
1969, WC added  environmental  consulting to its lines of business.  In the late
1970's WC  established  a  hazardous  waste  management  practice  and  European
operations.  WC  has  performed  work  for  the  Federal  government  since  its
formation,  and in the late  1980's  WC  formed  a  subsidiary  specifically  to
consolidate and expand its services to Federal government agencies. At that time
WC also expanded  geographically into the Asian-Pacific region and increased its
European operations.  In 1987 a holding company (Woodward-Clyde Group, Inc.) was
formed,  which  has since  moved  its  headquarters  to  Denver.  Woodward-Clyde
Consultants (now  Woodward-Clyde  International-Americas),  was at that time the
primary  operating  entity,  and became  WC's  major  subsidiary  following  its
incorporation.  In  1995  WC  acquired  Cole,  Sherman  &  Associates,  Ltd.,  a
full-service Canadian  engineering,  architectural design and planning firm, and
Geo-Con, a geotechnical and environmental  construction firm. These acquisitions
brought  WC  capacity  in  the  geo-civil   design  market  and  a  construction
subsidiary.

         WC offers a broad range of environmental engineering services,  ranging
from  planning  through  construction  of major  projects  for both  private and
governmental clients.  Services include implementation of solutions for problems
such as hazardous waste, air pollution, water pollution, facility permitting and
regulatory compliance. WC also provides specialized consulting services relating
to civil and  geotechnical  engineering,  geo-civil  design and construction and
water supply. Services offered by WC cover all phases of a project's life cycle,
including planning, consulting, permitting, design, construction and operations.

Services

         WC  separates  its  business  into  four  major  service  areas:  Waste
Management and Remediation  Engineering,  Environmental Management and Pollution
Control, Civil and Geo-Engineering and Construction Contracting.

         Waste Management.  Representing  nearly 41% of 1996 revenue,  the waste
management  area provides  greater revenue than any of WC's other service areas.
WC provides  integrated  services to characterize waste and site  contamination,
select appropriate  cost-effective  remedies,  engineer and design the remedies,
and then  implement the remedies  selected.  WC performs  environmental  audits,
environmental  site assessments and contamination  assessments,  provides health
risk assessment and cleanup criteria, and also performs engineering  feasibility
studies. In addition,  WC develops remediation plans, designs and specifications
for treatment,  storage and disposal,  including  in-plant  waste  minimization,
industrial  and municipal  wastewater  treatment,  landfill  siting,  design and
construction,  waste treatment and solid waste management. WC frequently manages
remedial  action,  as well as construction and  post-construction  environmental
monitoring. WC also performs remediation construction,  which is described below
in "Construction Contracting."

         Environmental   Management   and   Pollution   Control.   WC   performs
environmental impact assessments and mitigation studies as well as environmental
document  preparation  services  including  the  production  of both program and
project-level feasibility studies,  environmental  checklists,  initial studies,
environmental impact reports, environmental assessments, and permit applications
and similar  documents  required by Federal,  state and local agencies.  WC also
presents  documentary  findings  to  governmental  agencies  or other  firms and
provides  expert  testimony  at  administrative  and  judicial  hearings.  Other
environmental  services  provided by WC include  services  related to  strategic
environmental  management (including preparation for ISO 14000 certification and
remediation assessment); air pollution, including


                                       77

<PAGE>



air quality  impact  assessment,  engineering  and toxic air  emissions  control
program  development;   industrial  wastewater  treatment,  including  planning,
analysis,  design and  construction  management  for  wastewater  discharge  and
reclamation; and stormwater runoff management.

         Civil and Geo-Engineering.  WC was originally founded as a geotechnical
engineering firm specializing in soil mechanics and foundation engineering. WC's
primary services in this field include  foundation  engineering for all types of
man-made,  earth-based  structures.  WC has  developed  extensive  knowledge  in
underground construction,  including tunneling and deep open cut excavations. WC
has contributed in whole or in part to the design construction or rehabilitation
of over 2,000 dams worldwide,  and is experienced in engineering geology applied
to natural  hazard  assessment  and  mitigation,  such as landslides  and active
faults.  WC applies risk  assessment  and  management  services to the fields of
seismological  analysis  and  earthquake  engineering  design,  as well as water
supply and flood studies,  and assessment of health risks posed by industrial or
commercial  activities.  WC's primary  services  related to water supply include
surface and ground water hydrologic analysis; supply and demand studies; siting,
site investigations,  design and construction of dams and tunnels; and planning,
economic studies and management.  WC sites and designs major earth, rockfill and
concrete dams and tunnels,  and its services include  drawings,  specifications,
cost estimates and schedules.  Planning and  management  services  include river
basin  planning,   water  management  and  conservation  studies,  water  rights
evaluation,  conduct of public involvement and conflict  resolution programs and
various economic and cost-benefit analyses.

         Construction  Contracting.  WC  entered  the  construction  contracting
market  with  the  acquisition  of  Geo-Con  in  1995.  WC  provides   specialty
contracting services in several geotechnologies applicable to environmental site
restoration and soil improvement for infrastructure  projects.  In addition,  by
combining engineering and construction  capabilities,  WC is now able to provide
turnkey design/construct services to its clients.

Market Price of and Dividends on
Common Equity and Related Stockholder Matters

         Market  Information.  There is no established public trading for either
the WC Common Stock or WC  Preferred  stock.  WC Common  Stock is available  for
purchase only by selected professional employees of WC and its subsidiaries. The
price per share is set by the  Board of  Directors  not less than once per year,
which  price  pertains  until  a new  price  is  set,  in  accordance  with  the
Shareholders'  Agreement.  The Shareholders' Agreement provides a range in which
the Board of Directors may set the price per share: the price may not exceed 1.2
times the book value per share as reported in the latest financial statements of
WC,  and may not be set below a price 0.8 times the last  transaction  price per
share. The prices  determined by the Board of Directors for the periods covering
the last two fiscal years and latest interim periods are as follows:

                  January 1, 1997 to present:                          $ 25.00
                  August 1, 1995 to December 31, 1996:                 $ 23.60
                  January 1, 1995 to July 31, 1995:                    $ 23.00

         As previously  noted,  there is no public market for the trading of any
of WC Common Stock. WC Common Stock can be transferred,  once purchased, only to
WC or under certain limited  circumstances to other  employee-stockholders,  and
only  when  the  stockholder  ceases  to be an  employee  of WC or  one  of  its
subsidiaries,  upon the  attainment  by the employee of age 55, upon the special
vote of the Board of Directors and the stockholders, under certain circumstances
when WC is  unable to  purchase  the WC Common  Stock,  or if the  stockholder's
shares  become   "Qualified   Shares"  as  determined  in  accordance  with  the
Shareholders'  Agreement.  WC is not  required  to purchase  such shares  unless
certain  requirements  have been met, one of which is the  acceptability of such
purchase  under  applicable  lending  agreements.  Since late 1995,  WC has been
significantly restricted from purchasing shares by


                                       78

<PAGE>



certain terms of its lending arrangements.  There has been, therefore, a waiting
list of  stockholders  in line to have their  shares  purchased by WC when WC is
able to resume such purchases.

         There is likewise no public  market for the trading of any WC Preferred
Stock.  All of the issued and outstanding  shares of WC Preferred Stock are held
by the  General  Trustees  for the WC  Retirement  Plan,  which  is a  qualified
retirement  benefit  plan. An agreement  between WC and the General  Trustees in
1992 provides the General  Trustees a "put option" in the shares of WC Preferred
Stock,  in that 10% of the  outstanding  WC Preferred  Stock held by the General
Trustees as of the date of the  agreement  are subject to  repurchase by WC each
year.  However,  repurchases  in connection  with these put options of Preferred
Stock  have  been  restricted  in  accordance  with the  terms  of WC's  lending
arrangements.

         Holders. The WC Retirement Plan is the sole stockholder of WC Preferred
Stock.  Pursuant  to the  Shareholders'  Agreement,  WC Common  Stock is held by
employees of WC and the WC  subsidiaries.  As of August 26, 1997, there were 399
employee stockholders, none of whom owned 5% or more of WC Common Stock. At that
date,  there were also 91  non-employee  stockholders,  none of whom owned 5% or
more of WC Common Stock.  Non-employee  stockholding arises due to retirement or
termination of employees only. The non-employee  stockholders are currently on a
waiting  list to have  their  shares  purchased  by WC.  The terms of the Merger
Agreement  prevent WC from issuing or  repurchasing  any shares of its Common or
Preferred Stock until the  termination of the Merger  Agreement or the Effective
Time of the Merger.  Until such time,  existing  restrictions on WC's ability to
repurchase its shares also remain in effect.

         Dividends.  WC has never paid  dividends on the WC Common Stock.  Under
the  terms  of  the  WC  Financing  Agreement,  WC  and  certain  of  its  major
subsidiaries  are  prohibited  from paying any  dividends on their capital stock
without the prior written consent of the agent of the lenders. It is anticipated
that all indebtedness outstanding under the WC Financing Agreement will be fully
paid  and that the WC  Financing  Agreement  will be  terminated  following  the
consummation of the Merger.

Directors' Remuneration

         During  fiscal year 1996,  the  non-employee  members of URS's Board of
Directors  received an annual Director's fee of $15,000,  plus an attendance fee
of $2,000 for each Board of Directors  meeting attended in person,  and a fee of
$500  for  participation  in  any  Board  of  Directors  meeting  by  telephone.
Non-employee Directors who are members of a committee of the Board received $625
for  each  committee  meeting  attended  in  person,  and  a  fee  of  $500  for
participation  in any  committee  meeting  by  telephone.  The  Chairman  of the
committee received an additional $625 per meeting. Employee members of the Board
of  Directors  did not receive any such fees.  Non-employee  Directors  also are
entitled to participate, at URS's expense, in a medical benefit plan. Based upon
URS's  costs,  the  monetary  value  of  such  medical  benefit  plan  to  those
non-employee  Directors  participating in fiscal year 1996 was $7,476.  URS also
maintains a policy  whereby  non-employee  Directors may be hired on an asneeded
basis from time to time as consultants for special projects at the rate of up to
$3,000  per day  (plus  reasonable  expenses)  upon  the  recommendation  of the
Chairman of the Board or any officer  designated  by the  Chairman of the Board.
Upon  the  conclusion  of  each  annual  meeting  of  URS   stockholders,   each
non-employee  Director who was  reelected  to serve as a Director  automatically
receives  a stock  grant  equal to that  number of shares  of URS  Common  Stock
determined  by dividing  $15,000 by the closing price of the URS Common Stock on
the date of each annual meeting of stockholders.

Certain Relationships and Related Transactions

        Richard  C. Blum,  a  Director  of URS,  receives  $60,000  per year for
services provided under a consulting  agreement with URS. In addition,  URS pays
$90,000 per year to RCBA, L.P. under a separate  consulting  agreement.  URS may
terminate  these  consulting  agreements  at any time.  Mr. Blum is the majority
stockholder  of RCBA,  Inc.  RCBA,  Inc.,  in its  capacity as the sole  general
partner of RCBA,  L.P.,  indirectly  through several  entities,  holds 2,952,729
shares (assuming the exercise of certain warrants), or approximately 33 percent,
of URS's outstanding Common Stock.

Employment Agreements

Martin M. Koffel

        Mr. Koffel has an evergreen  employment  agreement with URS, executed in
December 1991, under which Mr. Koffel is eligible for a target bonus equal to 60
percent of his base  salary and  received an annual base salary of not less than
$385,000    through   December   17,   1995.   On   December   15,   1995,   the
Compensation/Option   Committee  increased  Mr.  Koffel's  annual  base  salary,
effective  December  18, 1995,  to  $415,000.  The  agreement  obligates  URS to
reimburse Mr. Koffel for the cost of maintaining  disability insurance providing
monthly  benefits of not less than  $10,000 in the event of his  disability  and
provides for certain supplemental life insurance benefits which currently are in
the form of a $1,155,000 term life insurance policy. If Mr. Koffel's  employment
is terminated  involuntarily by URS without cause (other than by reason of death
or  disability),  URS must pay a severance  payment  equal to 150 percent of his
then  current  base salary and his then  current  target  bonus.  If Mr.  Koffel
voluntarily resigns his employment within one year following a Change in Control
(see below),  or if Mr. Koffel is terminated for any reason other than for cause
at any time  after a  Change  of  Control,  he  becomes  entitled  to a  special
severance  payment  equal to 300 percent the sum of his then current base salary
and his then current  target bonus.  In addition,  all awards held by Mr. Koffel
under any of URS's incentive,  deferred  compensation,  bonus, stock and similar
plans, to the extent unvested,  will become vested immediately upon a "Change in
Control."  A "Change in Control"  is defined in the  agreement  to include (i) a
change in control required to be reported  pursuant to Item 6(e) of Schedule 14A
of  Regulation  14A under the  Securities  Exchange Act of 1934, as amended (the
"Exchange  Act"), or (ii) any person  acquiring 20 percent or more of the voting
power of URS or (iii) more than two-thirds of the Directors not having served on
the Board for 24 months  prior to the "Change in  Control."  On or about May 10,
1996,

Heartland Advisors,  Inc.  ("Heartland"),  one of URS's stockholders,  purchased
additional shares of URS's Common Stock, which increased  Heartland's  ownership
of outstanding  Common Stock from  approximately  19 percent to approximately 22
percent  (the  "Heartland  Transaction"),  resulting  in a technical  "Change of
Control"  under  Mr.  Koffel's  employment  agreement  and the  terms of the URS
Corporation  1991 Stock  Incentive  Plan (the  "1991  Plan").  As a result,  the
special  severance payment will now be payable to Mr. Koffel if he is terminated
for any  reason  other  than  for  cause  at any  time  during  the  term of his
employment agreement.  In addition, the options previously granted to Mr. Koffel
in 1994, 1995 and 1996 under the 1991 Plan are now fully vested.

        Under the terms of an earlier employment agreement executed in May 1989,
Mr.  Koffel was granted SARs on 15,000  shares at the base price of $28.75 which
expire  upon the  earlier  of May 9,  1999 or the  termination  of Mr.  Koffel's
employment  with URS.  At URS's  option,  Mr.  Koffel's  SARs may at any time be
replaced with options to purchase Common Stock on the same economic basis as the
SARs. The SARs are fully vested.

Irwin L. Rosenstein

         Mr. Rosenstein has an evergreen  employment  agreement with URS Greiner
Consultants,  Inc., executed in August 1991, under which Mr. Rosenstein received
an annual  base  salary of not less than  $300,000  from  March 2, 1992  through
December 17,  1995.  On December 15,  1995,  the  Compensation/Option  Committee
increased Mr. Rosenstein's  annual base salary,  effective December 18, 1995, to
$315,000.  The  agreement  also  obligates  URS to maintain a $400,000 term life
insurance policy for Mr. Rosenstein and disability  insurance providing him with
benefits  of at least  $7,000 per month in the event of his  disability.  If Mr.
Rosenstein's employment is terminated  involuntarily by URS without cause (other
than by reason of death or  disability)  he is entitled to  continuation  of his
base salary for one year (or until normal retirement at age 65, if less).  Under
the agreement, as amended, if Mr. Rosenstein ceases to be employed by URS within
one year  following a "Change of Control" (see below),  Mr.  Rosenstein  will be
entitled to receive a severance payment equal to 200 percent of his then current
base salary. A "Change in Control" is defined in Mr.  Rosenstein's  agreement as
the acquisition by any person of 51 percent of more of URS Greiner  Consultants,
Inc.'s or URS's then current outstanding  securities having the right to vote at
elections of Directors. The Heartland Transaction did not result in a "Change of
Control"  under  Mr.  Rosenstein's  employment  agreement,  but  resulted  in  a
technical  "Change  of  Control"  under  certain  stock  options  granted to Mr.
Rosenstein in 1995 under the 1991 Plan. As a result,  such options are now fully
vested.

        Under the terms of an earlier employment  agreement executed in February
1989,  Mr.  Rosenstein  was  granted  SARs on 7,500  shares at the base price of
$27.50 which expire upon the earlier of February 24, 1999 or the  termination of
Mr. Rosenstein's employment with URS. At URS's option, Mr. Rosenstein's SARs may
at any time be  replaced  with  options  to  purchase  Common  Stock on the same
economic basis as the SARs. The SARs are fully vested.

Robert L. Costello

        Mr. Costello has an employment agreement with Greiner, Inc. ("Greiner"),
a wholly-owned  subsidiary of URS,  executed in March 1996, which provides for a
term of three years (unless terminated earlier as provided therein), under which
Mr.  Costello  receives an annual base salary of not less than $250,000.  If Mr.
Costello's  employment  is  terminated  involuntarily  by Greiner  without cause
(other  than by  reason  of death or  disability)  or Mr.  Costello  voluntarily
resigns  his  employment  in the event that his salary is reduced or Greiner has
breached  its  obligation  to employ Mr.  Costello in an  executive  position as
described in the  agreement,  Greiner must pay a severance  payment equal to 100
percent of his then  current  base salary less base salary paid to Mr.  Costello
for any period up to one month between the date of termination and the date that
notice thereof is given plus any accrued and unpaid vacation at the time of such
termination.  Under the agreement,  if Mr. Costello ceases to be employed by URS
within one


                                       87

<PAGE>



year following a "Change of Control" (see below),  Mr. Costello will be entitled
to receive a severance  payment  equal to 200 percent of his then  current  base
salary.  A "Change in Control"  is defined in Mr.  Costello's  agreement  as the
acquisition  by any  person of 51  percent  of more of  Greiner's  or URS's then
current  outstanding  securities  having  the  right  to  vote at  elections  of
Directors.  The  Heartland  Transaction  did not result in a "Change of Control"
under Mr. Costello's employment agreement.

Kent P. Ainsworth

        Mr. Ainsworth executed an evergreen employment agreement with URS in May
1991  following  his  employment  as URS's Vice  President  and Chief  Financial
Officer in January 1991. Under this employment agreement, Mr. Ainsworth received
an annual base salary of $165,000 from February 24, 1992 through March 22, 1993,
$185,000  through  December 14, 1994 and $195,000  through December 17, 1995. On
December 15, 1995, the  Compensation/Option  Committee increased Mr. Ainsworth's
annual base salary, effective December 18, 1995, to $205,000. On March 26, 1996,
the Committee increased Mr. Ainsworth's annual base salary,  effective March 29,
1996, to $220,000,  and approved the payment of a special bonus to Mr. Ainsworth
in the amount of  $50,000  in  recognition  of his work in  connection  with the
acquisition of GEI. If Mr. Ainsworth's employment is terminated involuntarily by
URS without cause (other than by reason of death or disability),  he is entitled
to continuation  of his base salary for one year (or until normal  retirement at
age 65, if less).  If Mr.  Ainsworth  voluntarily  resigns  his  employment  for
specified  reasons  within one year  following  a Change in Control  (as defined
above  in the  description  of Mr.  Koffel's  employment  agreement),  or if Mr.
Ainsworth is terminated for any reason at any time after a Change of Control, he
becomes entitled to a special severance payment equal to 280 percent of his then
current base salary  (reduced  pro rata if such  termination  occurs  within two
years prior to normal retirement). In addition, all awards held by Mr. Ainsworth
under any of URS's incentive,  deferred  compensation,  bonus, stock and similar
plans, to the extent unvested,  will become vested immediately upon a "Change of
Control." The Heartland  Transaction resulted in a technical "Change of Control"
under Mr. Ainsworth's  employment agreement and the terms of the 1991 Plan. As a
result, the special severance payment will now be payable to Mr. Ainsworth if he
is  terminated  for any  reason at any time  during  the term of his  employment
agreement. In addition, the options previously granted to Mr. Ainsworth in 1994,
1995 and 1996 under the 1991 Plan are now fully vested.

Joseph Masters

        Mr. Masters does not have a written  employment  agreement with URS. Mr.
Masters's   compensation  is  reviewed  and  established   periodically  by  the
Compensation/Option  Committee.  Effective March 17, 1997, Mr.  Masters's annual
base salary was increased  from  $140,000 to $150,000 and on July 15, 1997,  Mr.
Masters's  annual base  salary was  increased  from  $150,000 to $165,000 by the
Compensation/Option  Committee.  Mr. Masters has a severance agreement with URS,
executed on November 22, 1993,  which provides that if Mr. Masters is terminated
by URS at any time during the term of the agreement  other than for cause, or if
Mr. Masters voluntarily leaves for specified reasons within one year following a
"Change  of  Control"  (as  defined  above in the  description  of Mr.  Koffel's
employment  agreement),  he will be  entitled  to  receive  his base  salary and
participate in any insurance plans  maintained by URS during a severance  period
commencing on the date his  employment  terminates  and ending on the earlier of
six months thereafter or his death.

               COMPARISON OF RIGHTS OF STOCKHOLDERS OF URS AND WC

        Both URS and WC are incorporated in the State of Delaware and subject to
the  provisions of the Delaware  General  Corporation  Law. For this reason,  by
reason of receiving URS Common Stock,  following the Merger WC stockholders will
continue to hold stock of a corporation  subject to the same  corporations  law.
However,  following the Merger, WC stockholders will be subject to URS's charter
documents  and  there  are a number  of  differences  between  such URS  charter
documents and WC's charter  documents.  The following is a summary comparison of
certain  differences  affecting  stockholder rights in the charter documents and
bylaws of URS and WC. This summary does not purport to be a complete  discussion
of, and is  qualified  in its  entirety  by  reference  to, the URS  Amended and
Restated  Certificate  of  Incorporation  and Bylaws and the WC  Certificate  of
Incorporation and Bylaws.

        The  Certificate  of  Incorporation  and  Bylaws  of  each of URS and WC
contain  certain  differences.  In URS's Bylaws,  the President may call special
meetings of the stockholders, and the President and the Secretary must call such
meetings upon written request by the URS Board of Directors or the holders of at
least 20 percent of the  outstanding  URS stock  entitled to vote.  In contrast,
WC's  Bylaws  provide  that  the  Chairman  may  call  special  meetings  of the
stockholders,  and that the Chairman and the  Secretary  must call such meetings
upon written  request of a majority of the Board of Directors or WC stockholders
entitled to vote.  URS's Bylaws  provide that URS Board of Directors  may not be
less than five nor more than fifteen persons, to be determined from time to time
by resolution of the URS Board of Directors or the  stockholders at their annual
meeting. The URS Board of Directors currently consists of eleven members. The WC
Bylaws set the number of  directors  at twelve.  URS does not have a  classified
Board of Directors  under its Bylaws or its Amended and Restated  Certificate of
Incorporation. Under its


                                       92

<PAGE>



Bylaws, WC does not have a strictly  classified  Board, but different  directors
are elected to staggered terms of office. URS's Amended and Restated Certificate
of  Incorporation  provides  for the  elimination  of personal  liability of the
directors  to the  corporation  or its  stockholders  for  certain  breaches  of
fiduciary duty. WC's Certificate of Incorporation contains no such provisions.

        In addition, holders of WC Common Stock are subject to the provisions of
the  Shareholders'  Agreement,  and are being  asked to amend the  Shareholders'
Agreement to remove all restrictions  and  requirements  which prohibit or would
prevent  the  transactions  contemplated  by the Merger  Agreement.  See "The WC
Meeting" and  "Information  Concerning  WC -- Market  Price of and  Dividends on
Common Equity and Related Stockholder Matters."


              AFFILIATES' RESTRICTIONS ON SALE OF URS COMMON STOCK

        The shares of URS Common  Stock to be issued to the holders of WC Common
Stock as a result of the Merger will have been  registered  under the Securities
Act,  will be  listed  on the  NYSE and the PE and  will be  freely  marketable.
However, any holder of WC Common Stock who is deemed to be an affiliate of WC at
the Effective Time of the Merger and any such person who becomes an affiliate of
URS as a result of or  following  the  Merger  will be subject to the volume and
manner of sale restrictions  imposed on resales of the URS Common Stock by Rules
144 and 145 under the  Securities  Act.  In  addition,  in  connection  with the
Merger,  each  officer,  director  and holder of one percent (1%) or more of the
outstanding  shares of WC Common Stock will be asked to provide a continuity  of
interest  representation  in a manner  sufficient to satisfy the requirements of
the  Internal   Revenue  Code  for   treatment  of  the  Merger  as  a  tax-free
reorganization. See "The Merger - Certain Federal Income Tax Matters."

        The Merger Agreement requires WC affiliates to enter into agreements not
to make any sale of URS Common  Stock  received  upon  conversion  of WC Capital
Stock in the Merger except in compliance with Rule 145 under the Securities Act.
See "The Merger -- The Merger Agreement." In general,  Rule 145, as currently in
effect, imposes restrictions on the manner in which such affiliates,  who remain
affiliates  of URS after the Merger,  may make  resales of URS Common  Stock and
also on the  number of shares of URS  Common  Stock  that such  affiliates,  and
others  (including  persons with whom the affiliates  act in concert),  may sell
within any three-month  period.  These  restrictions will generally apply for at
least a period of two years after the Merger (or longer if the person remains an
affiliate of URS).

                                  LEGAL MATTERS

        Certain  legal  matters with respect to the validity of URS Common Stock
to be issued in connection with the Merger are being passed on for URS by Cooley
Godward LLP, San Francisco, California. Bronson, Bronson & McKinnon LLP, counsel
to WC, and Cooley  Godward LLP,  counsel to URS,  have each  rendered an opinion
that the Merger will  constitute a  reorganization  under Section  368(a) of the
Code.

                        REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Directors and Stockholders of URS Corporation:

         We have audited the  accompanying  consolidated  balance  sheets of URS
Corporation  and its  subsidiaries  as of  October  31,  1996 and 1995,  and the
related consolidated  statements of operations,  changes in stockholders' equity
and cash flows for each of the three years in the period ended October 31, 1996.
These financial  statements are the responsibility of the Company's  management.
Our responsibility is to express an opinion on these financial  statements based
on our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion,  the  financial  statements  referred to above  present
fairly, in all material  respects,  the consolidated  financial  position of URS
Corporation  and its  subsidiaries  as of  October  31,  1996 and 1995,  and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended October 31, 1996, in conformity  with  generally
accepted accounting principles.



                                                     /s/Coopers & Lybrand L.L.P.

                        URS CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1.   ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

         The  consolidated  financial  statements  include  the  accounts of URS
Corporation and its subsidiaries, all of which are wholly-owned. All significant
intercompany  accounts and transactions  have been eliminated in  consolidation.
The  consolidated  financial  statements  account for the acquisition of Greiner
Engineering,  Inc.  ("Greiner")  in  March,  1996  as a  purchase.  (See  Note 3
Acquisitions.)

Use of Estimates

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  effect  the  reported  amount of assets and  liabilities  and
disclosures  of contingent  assets and  liabilities at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Revenue Recognition

         Revenue    from    contract    services    is    recognized    by   the
percentage-of-completion  method  and  includes  a  proportion  of the  earnings
expected to be realized on a contract in the ratio that costs  incurred  bear to
estimated  total costs.  Revenue on cost  reimbursable  contracts is recorded as
related  contract costs are incurred and includes  estimated  earned fees in the
proportion that costs incurred to date bear to total estimated  costs.  The fees
under certain  government  contracts may be increased or decreased in accordance
with cost or performance  incentive  provisions which measure actual performance
against  established  targets or other  criteria.  Such  incentive fee awards or
penalties  are  included in revenue at the time the  amounts  can be  reasonably
determined.  Revenue for additional  contract  compensation  related to unpriced
change orders is recorded when  realization is probable.  Revenue from claims by
the Company for additional  contract  compensation is recorded when agreed to by
the  customer.  If estimated  total costs on any contract  indicate a loss,  the
Company provides currently for the total loss anticipated on the contract.

         Costs  under  contracts  with  the  U.S.   Government  are  subject  to
government  audit upon  contract  completion.  Therefore,  all  contract  costs,
including  direct  and  indirect,   general  and  administrative  expenses,  are
potentially  subject  to  adjustment  prior to final  reimbursement.  Management
believes that adequate provision for such adjustments,  if any, has been made in
the accompanying consolidated financial statements. All overhead and general and
administrative  expense  recovery  rates for fiscal 1989 through fiscal 1996 are
subject to review by the U.S. Government.

Cash and Cash Equivalents

         The Company  considers  all highly  liquid  investments  with  original
maturities of three months or less to be cash equivalents.

Fair Value of Financial Instruments

         Carrying  amounts  of certain of the  Company's  financial  instruments
including cash,  accounts  receivable,  accounts  payable and other  liabilities
approximate fair value due to their short  maturities.  Based on borrowing rates
currently  available to the Company for loans with similar  terms,  the carrying
values of long term debt approximate fair value.

Income Taxes

         The  Company  uses  an  asset  and  liability   approach  to  financial
accounting  and  reporting  for  income  taxes.  Deferred  income tax assets and
liabilities  are  computed  annually  for  differences   between  the  financial
statement and tax bases of assets and liabilities that will result in taxable or
deductible  amounts in the future based on enacted tax laws and rates applicable
to the periods in which the  differences  are expected to affect taxable income.
Valuation  allowances  are  established  when  necessary to reduce  deferred tax
assets to the amount  expected  to be  realized.  Income tax  expense is the tax
payable  for the  period  plus or minus the  change in  deferred  tax assets and
liabilities during the period.

Property and Equipment

         Property  and  equipment  are  stated at cost.  In the year  assets are
retired or otherwise disposed of, the costs and related accumulated depreciation
are removed  from the  accounts  and any gain or loss on disposal is included in
income.  Depreciation  is provided on the  straight-line  method over the useful
service  lives of the assets.  Leasehold  improvements  are  amortized  over the
length of the lease or estimated useful life, whichever is less.

Income Per Share

         The computation of earnings per common and common  equivalent shares is
based upon the weighted average number of common shares  outstanding  during the
period  plus (in  periods in which they have a  dilutive  effect)  the effect of
common shares contingently issuable,  primarily from stock options,  exercise of
warrants and the potential conversion of convertible debentures, less the number
of shares  assumed to be purchased  from the proceeds  using the average  market
price of the Company's common stock.

         The fully diluted per share  computation  reflects the effect of common
shares  contingently  issuable upon the exercise of warrants in periods in which
such exercise would cause  dilution.  Fully diluted  earnings per share may also
reflect  additional  dilution  related  to stock  options  due to the use of the
market price at the end of the period when higher than the average price for the
period.

     In March 1995, the Financial  Accounting  Standards  Board ("FASB")  issued
Statement of Financial  Accounting Standards No. 121, "Accounting for Long-Lived
Assets and for  Long-Lived  Assets to be  Disposed  of" ("SFAS  121").  SFAS 121
requires that long-lived assets, certain identifiable intangibles,  and goodwill
be reviewed for impairment whenever events or changes in circumstances  indicate
that the carrying amount may not be recoverable. Impairment would be recorded if
the expected future  undiscounted  cash flows were less than the carrying amount
of the asset.  SFAS 121 is effective for fiscal years  beginning  after December
15,  1995,  with  earlier  adoption  permitted.  The Company will adopt SFAS 121
effective  for its fiscal year ending  October 31,  1997.  The Company  does not
believe  that  adoption of SFAS 121 will have a material  adverse  effect on its
financial position or results of operations.

     In  October  1995,  the  FASB  issued  Statement  of  Financial  Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), which
is  effective  for fiscal years  beginning  after  December  15, 1995.  SFAS 123
encourages  entities  to adopt a fair  value  based  method  of  accounting  for
employee stock compensation plans; however, it also allows an entity to continue
to measure  compensation  cost for those plans using the  intrinsic  value based
method of accounting.  Under the intrinsic value based method,  companies do not
recognize  compensation cost for many of their stock  compensation  plans. Under
the fair value based method,  companies would recognize  compensation  costs for
those same plans.  The Company  elects to  continue to use the  intrinsic  value
based  method,  and  therefore  does not  expect  the  impact  on its  financial
statements, if any, to be material.

Reclassifications

     Certain  reclassifications  have been  made to the 1995 and 1994  financial
statements to conform to the 1996  presentation  with no effect on net income as
previously reported.

NOTE 2.   QUASI-REORGANIZATION

     In  conjunction  with a  restructuring  completed in fiscal year 1990,  the
Company,   with  the  approval  of  its  Board  of   Directors,   implemented  a
quasi-reorganization effective February 21, 1990 and revalued certain assets and
liabilities to fair value as of that date.

     The fair values of the Company's  assets and liabilities at the date of the
quasi-reorganization were determined by management to approximate their carrying
value and no further adjustment of historical bases was required. No assets were
written-up   in   conjunction   with   the   revaluation.   As   part   of   the
quasi-reorganization,  the  deficit in retained  earnings  of $92.5  million was
eliminated against additional paid-in capital.  The balance in retained earnings
at October 31, 1996 represents the accumulated net earnings  arising  subsequent
to the date of the quasi-reorganization.


NOTE 3.   ACQUISITIONS

     During the year ended October 31, 1995, the Company  acquired E.C. Driver &
Associates,  Inc. ("ECD") for an aggregate  purchase price of $3.6 million,  and
the assumption of ECD's liabilities totaling $1.4 million.  This acquisition was
accounted for by the purchase method of accounting and the net assets of ECD are
included in the Company's consolidated balance sheet


                                       F-9

as  of  October  31,  1995  based  upon  their   estimated  fair  value  at  the
transaction's effective date of January 4, 1995. Pro forma operating results for
the years ended October 31, 1994 and 1995, as if the  acquisition  had been made
on November 1, 1993, are not presented as they would not be materially different
from the Company's  reported results.  The excess of the purchase price over the
estimated fair value of the assets acquired has been allocated to goodwill.

     During the year ended October 31, 1996, the Company acquired Greiner for an
aggregate  purchase price of $78.8 million,  comprised of cash of $69.3 million,
and 1.4 million shares of the Company's  Common Stock.  The acquisition has been
accounted for by the purchase  method of  accounting  and the excess of the fair
value of the net assets  acquired over the purchase  price has been allocated to
goodwill. The operating results of Greiner are included in the Company's results
of operations from the date of purchase.

         As of October 31, 1996,  the Company has available  net operating  loss
("NOL")  carryforwards  for Federal income tax purposes and financial  statement
purposes of $6.0 million. The NOL utilization is limited to $750,000 per year.

         While the Company  had  available  NOL  carryforwards  which  partially
offset otherwise  taxable income for Federal income tax purposes,  for state tax
purposes such amounts are not necessarily  available to offset income subject to

      The net change in the total valuation allowance for the year ended October
31, 1996 was a decrease  of $788,000  due to the  utilization  of net  operating

     At October 31, 1996, the Company's senior secured revolving credit facility
with Wells Fargo Bank,  N.A.  (the  "Bank")  provides  for  advances up to $20.0
million and expires March 29, 1999.  Borrowings on the revolving credit facility
bear interest at the option of the Company based on rate indexes selected by the
Company,  with variable  spreads over the selected  index based on loan maturity
and the Company's financial performance.  At October 31, 1996, the interest rate
was based on the London Interbank  Offered Rate ("LIBOR") of 5.53%, plus spreads
of 2.625% to 3.00%. At October 31, 1996, the Company had outstanding  letters of
credit totaling $600,000 which reduced the amount available to the Company under
its revolving credit facility to $19.4 million.

     Also at October 31, 1996, the Company had  outstanding  with the Bank $49.2
million of senior secured term loans payable over seven years beginning  October
1996.  The loans bear  interest  based on rate indexes  selected by the Company,
with  variable  spreads over the selected  index based on loan  maturity and the
Company's  financial  performance.  At October 31, 1996,  the interest  rate was
based on the LIBOR of 5.53%, plus spreads of 2.625% to 3.00%.

Related Parties

     At October 31, 1996,  the Company had  fully-drawn  $4.0 million  under its
line  of  credit  with  Richard  C.  Blum  &  Associates,   Inc.  ("RCBA").  The
indebtedness is represented by the January Notes,  which bear interest at 6 1/2%
per annum,  are subordinate only to the Bank line of credit and are due November
1, 2000. RCBA, through various partnerships, beneficially owns approximately 18%
of  the  Company's  common  shares   (approximately  33%  assuming  exercise  of
additional  warrants)  outstanding  at October  31,  1996.  Richard  C. Blum,  a
director of the Company, is also Chairman of RCBA.

Debentures

     The  Company's  6 1/2%  Convertible  Subordinated  Debentures  due 2012 are
convertible  into the Company's  common shares at the rate of $206.30 per share.
Sinking fund payments are  calculated to retire 70% of the  debentures  prior to
maturity  beginning  in  February  1998.  Interest is payable  semi-annually  in
February and August.  Interest is payable  semi-annually  in January and July on
the Company's 85/8% Senior Subordinated Debentures due 2004 ("85/8 Debentures").
Both the 6 1/2% Convertible  Subordinated Debentures and the 85/8 Debentures are
subordinate to all debt to RCBA and the Bank.

Maturities

     The amounts of long-term  debt  outstanding at October 31, 1996 maturing in
the next five years are as follows:

fiscal years ended October 31, 1996,  1995 and 1994  amounted to $10.9  million,
$5.7 million and $5.3  million,  respectively.  Certain of the lease rentals are

NOTE 8.   COMMITMENTS AND CONTINGENCIES

     Currently,  the Company  has $51.0  million per  occurrence  and  aggregate
commercial general liability insurance coverage. The Company is also insured for
professional  errors and omissions  ("E&O") and contractor  pollution  liability
("CPL")  claims with an aggregate  limit of $30.0 million  after a  self-insured
retention  of $.5  million.  The E&O and CPL  coverages  are on a "claims  made"
basis,  covering only claims actually made during the policy period currently in
effect.  Thus, if the Company does not continue to maintain this policy, it will
have no  coverage  under the policy for claims made after its  termination  date
even if the  occurrence  was during the term of  coverage.  It is the  Company's
intent to maintain this type of coverage, but there can be no assurance that the
Company can  maintain  its  existing  coverage,  that claims will not exceed the
amount of insurance  coverage or that there will not be claims relating to prior
periods that were subject only to "claims made" coverage.

     Various  legal   proceedings   are  pending  against  the  Company  or  its
subsidiaries  alleging breaches of contract or negligence in connection with the
performance of professional services. In some actions punitive or treble damages
are sought which  substantially  exceed the Company's  insurance  coverage.  The
Company's  management does not believe that any of such  proceedings will have a
material adverse effect on the consolidated financial position and operations of
the Company.

NOTE 9.   CAPITAL STOCK

     Declaration of dividends,  except Common Stock dividends,  is restricted by
the  Bank  line  of  credit  agreement  and the  Indenture  governing  the  85/8
Debenture.  Further,  declaration  of  dividends  may be  precluded  by existing
Delaware law.

     During fiscal year 1995,  the Company  repurchased a total of 42,000 shares
of its  Common  Stock at an average  repurchase  price of $5.43,  pursuant  to a
systematic  repurchase  plan  approved by the  Company's  Board of  Directors on
September  13, 1994.  The  systematic  repurchase  plan expired on September 13,
1995. The Company,  as of that date, had repurchased a total of 52,000 shares of
its Common Stock at an average repurchase price of $5.49.

     The 1987  Restricted  Stock Plan (the "Plan")  provides for grants of up to
16,537  shares  of  Common  Stock  to key  employees  of  the  Company  and  its
subsidiaries.  An employee selected to receive shares under the Plan will not be
required to pay any consideration  for the shares.  Shares issued to an employee
are  subject to  forfeiture  in the event that the  employment  of the  employee
terminates for any reason other than death.  The forfeiture  restrictions  lapse
with respect to portions of the grant over a five-year period  subsequent to the
grant date. As of October 31, 1996, 6,872 restricted shares have been granted.

     The 1979 Stock Option Plan (the "1979 Plan") provided for grants of options
to purchase  shares of Common Stock to directors,  officers and key employees of
the Company and its  subsidiaries  at prices and for periods  (not to exceed ten
years) as determined by the Board of Directors.  The 1979 Plan also provided for
the granting of Stock Appreciation Rights and incentive stock options.  The 1979
Plan expired in February 1989,  and no further  options or rights may be granted
under the 1979 Plan.

     On October 20, 1988, the stockholders approved a replacement option program
pursuant  to which  non-management  members  of the Board of  Directors  granted
replacement  stock options to selected  employees,  exercisable  at then current
market prices. The selected  employees then exchanged their outstanding  options
for new options covering two shares for each three shares covered by the options
being   replaced.   Options  to  purchase   16,561  shares  were  exchanged  for
pre-existing options.

     On April 27,  1989,  the  stockholders  approved  the 1989 Stock Option and
Rights Plan (the "1989  Plan").  The 1989 Plan provides for the grant of options
to  purchase  50,000  shares  of Common  Stock to  directors,  officers  and key
employees of the Company and its  subsidiaries at prices and for periods (not to
exceed ten years) as determined  by the Board of  Directors.  The 1989 Plan also
provides for the  granting of Stock  Appreciation  Rights.  No options have been
granted under the 1989 Plan.

     On March 26, 1991, the stockholders  approved the 1991 Stock Incentive Plan
(the "1991 Plan").  The 1991 Plan provides for the grant not to exceed 1,500,000
Restricted Shares, Stock Units and Options,  plus the number of shares of Common
Stock  remaining  available  for awards under the 1987 Plan (9,665) and the 1989
Plan (50,000) to key employees of the Company and its subsidiaries at prices and
for periods as  determined by the Board of  Directors.  The 1991 Plan  prohibits
granting new options  under the 1987 Plan and the 1989 Plan. As of October 1996,
the Company had issued 21,200 shares of Restricted Stock under the 1991 Plan.

     Under the Employee  Stock  Purchase  Plan (the "ESP Plan")  implemented  in
September  1985,  employees may purchase  shares of Common Stock through payroll
deductions of up to 10% of the employee's base pay.  Contributions  are credited
to each  participant's  account on the last day of each six-month  participation
period of the ESP Plan (which  commences  on January 1 and July 1 of each year).
The  purchase  price for each share of Common Stock shall be the lower of 85% of
the  fair  market  value  of such  share  on the last  trading  day  before  the
participation  period commences or 85% of the fair market value of such share on
the last trading day in the  participation  period.  Employees  purchased 69,692
shares under the ESP Plan in fiscal 1996 and 46,610 shares in fiscal 1995.

     On February 21, 1990,  the Company  issued  warrants to purchase  1,819,148
shares of Common  Stock at a purchase  price of $4.34 per share which  expire on
February 14, 1997.

1991 Plans is as follows:

NOTE 14.   CONCENTRATION OF CREDIT RISK

     The  Company  provides  services  primarily  to local,  state  and  Federal

evaluations of its customers and, generally, requires no collateral. The Company
maintains  reserves for potential credit losses and such losses have been within
management's  expectations.  Substantially  all  cash  balances  are held in one
financial institution and at times exceed federally insured limits.

                         Report of Independent Auditors

Board of Directors
Woodward-Clyde Group, Inc.

We have audited the accompanying  consolidated  statements of financial position
of Woodward-Clyde Group, Inc. and subsidiaries as of December 31, 1996 and 1995,
and the related consolidated statements of income, shareholders' equity and cash
flows for each of the three years in the period ended  December 31, 1996.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly,  in all  material  respects,  the  consolidated  financial  position  of
Woodward-Clyde  Group,  Inc. and subsidiaries at December 31, 1996 and 1995, and
the  consolidated  results of their  operations and their cash flows for each of
the three years in the period  ended  December  31,  1996,  in  conformity  with
generally accepted accounting principles.

1.  Significant Accounting Policies

Organization

Woodward-Clyde   Group,   Inc.  and  its  subsidiaries   (the  Company)  provide
geotechnical,  waste  management  and  environmental  consulting  services  with
offices in North  America,  Western  Europe  and the Asia  Pacific  region.  The
Company  also  provides   contract   services  to  the   remediation  and  civil
construction   industry  for  on-site   pollution   control  and  cleanup.   The
consolidated  financial statements include the accounts of Woodward-Clyde Group,
Inc. and its wholly owned subsidiaries.  Significant  intercompany  accounts and
transactions have been eliminated in consolidation.

Contract Revenues and Related Costs

The Company  recognizes income on the accrual basis and performs work under both
fixed price and  reimbursable  cost plus fee  contracts.  Revenues on  cost-type
contracts  are  recognized  as costs are incurred and include  estimated  earned
fees.   Revenues  on   fixed-price-type   contracts  are  recognized  using  the
percentage-of-completion  method by comparing costs of progress completed during
the period to total expected costs of the contracts.

Revenues  recognized  on  contracts  in  process  that are in excess of  related
billings are recorded as unbilled revenues. These amounts are generally billable
upon delivery or satisfaction of contract requirements specific to each project.

Provisions for estimated losses on contracts are recorded when identified.

Receivables

Retainage  balances are expected to be substantially  collected within one year.
Credit is extended based on an evaluation of the client's  financial  condition,
and  collateral  is  generally  not  required.  Provision  for  losses  has been
consistently within management's expectations.

Cash and Cash Equivalents

The Company  considers all  investments  with a maturity of three months or less
when purchased to be cash equivalents.  Cash and available-for-sale  investments
at December 31, 1996 and 1995, of $6,086,785, and $7,343,260 respectively,  were
held in bank and investment accounts of the Company's offshore captive insurance
company.

1. Significant Accounting Policies (continued)

Intangible Assets

The excess of cost over net assets of  subsidiaries  at acquisition is amortized
over 10 to 40 years.

Property and Equipment

Provision  for  depreciation  and  amortization  of property  and  equipment  is
computed by the straight-line method over estimated useful lives as follows:

Buildings                                25 to 30 years
Transportation equipment                 3 to 6 years
Other equipment                          3 to 10 years
Software                                 2 to 3 years
Leasehold improvements                   Life of lease or estimated useful life,
                                         whichever is shorter

In March 1995, the Financial  Accounting Standards Board (FASB) issued Statement
No. 121,  Accounting for the Impairment of Long-Lived  Assets and for Long-Lived
Assets to be Disposed Of,  which  requires  impairment  losses to be recorded on
long-lived  assets used in operations when indicators of impairment are present.
The Company adopted  Statement No. 121 effective  January 1, 1996 and the effect
of adoption was not material.

Property Held for Resale

The Company has acquired  certain  properties held for resale in connection with
claim settlements and values these properties at the lower of cost or market.

Foreign Currency Translation

The effects of foreign  exchange  rate  fluctuations  for countries in which the
Company  operates are included in the foreign  currency  translation  adjustment
account within shareholders' equity.

Fair Values of Financial Instruments

The  Company's  financial  instruments  consist  principally  of cash  and  cash
equivalents, receivables and unbilled revenues, loans payable to banks, accounts
payable,  and long-term debt. All of the Company's  financial  instruments  have
fair values which approximate their recorded values as the financial instruments
are either short-term in nature or carry interest rates which approximate market
rates.

Use of Estimates

The preparation of the Company's consolidated financial statements in conformity
with  generally  accepted  accounting  principles  requires  management  to make
estimates  and  assumptions  that  affect  the  reported  amounts  of assets and
liabilities  and disclosure of contingent  assets and liabilities at the balance
sheet  dates and the  reported  amounts  of  revenues  and  expenses  during the
reporting periods for long-term contracts.

The Company has a substantial history of making reasonably  dependable estimates
of the extent of progress towards  completion,  contract revenues,  and contract
costs on its contracts. However, due to uncertainties inherent in the estimation
process, actual results could differ from those estimates.

2.  Business Combinations

On April 28,  1995,  the  Company  purchased  all of the issued and  outstanding
common stock of GCH Acquisition Corporation (GCH) for $8,150,000,  for which the
Company paid cash of  $7,146,878  and issued  43,614  shares of its Common Stock
with a value of $1,003,122. The transaction was accounted for under the purchase
method of accounting.  Of the purchase price,  $5,221,000 was recorded as excess
of cost of net  assets  acquired  (goodwill).  The  consolidated  results of the
Company include the results of GCH since the date of  acquisition.  During 1996,
an  additional  amount of goodwill was  recognized  for the GCH  acquisition  of
$3,466,000,  net of taxes, as a result of changes in estimated  profitability of
contracts acquired.  These contracts were in process or completed at the date of
acquisition.  There are  acquisition  provisions for  additional  purchase price
consideration  to be paid to the former  owners of GCH of a  contingent  nature;
however, such amounts have not been recognized because payment is not probable.

In March 1996, the Company sued certain former owners of GCH, seeking relief for
injury  caused to the  Company  and GCH  through  their  misrepresentations  and
omissions  at the time GCH was sold to the  Company.  The  action  seeks  actual
damages,  costs, interest and attorneys' fees from the defendants.  The ultimate
resolution  of this  matter is  uncertain,  but it is  possible  this action may
result in future adjustment to GCH's and the Company's financial statements.

2. Business Combinations (continued)

In April 1996, two former shareholders and officers of GCH each sued GCH and the
Company for breach of employment  contract,  for intentional  interference  with
contractual  relations  and for breach of contract  related to their  respective
agreements as shareholders of the Company.  Management believes these suits have
no merit and intends to defend against them vigorously.

On October 3, 1995, the Company  purchased 100% of the outstanding stock of Cole
Sherman and Associates  Limited (CSA), a Canadian  corporation,  for $1,429,646.
The transaction  was accounted for under the purchase method of accounting.  The
consolidated results of the Company include the results of CSA since the date of
acquisition.   During  1996,  the  Company  wrote  off  uncollectible   accounts
receivable at CSA of  approximately  $217,000.  Since these accounts  receivable
were acquired as part of the purchase of CSA, this adjustment has been reflected
in the  Company's  reallocation  of  purchase  price to CSA's  net  assets,  and
goodwill has been adjusted for the same amount.

3.  Contributions to WCG CAP

The Woodward-Clyde  Group Capital Accumulation Plan Trust (WCG CAP) is a defined
contribution  plan (401(k) Plan) covering all employees  except for employees of
one subsidiary which maintains its own plan.  Employees may contribute up to 15%
of their compensation for each plan year, subject to the maximum allowable under
current  tax  regulations.  The Company  matches  contributions  for U.S.  based
employees  with  one  or  more  years  of  service  up to  2%  of an  employee's
compensation and matches 50% of contributions on the next 4% of compensation. An
additional  contribution of $25 to $250,  depending on compensation,  is made to
eligible employees earning less than $45,000 per year whether or not they choose
to make 401(k) Plan  contributions.  The Company  contributed  $2,956,945 to the
401(k) Plan for the year ended December 31, 1996.

Prior to January  1, 1996,  the WCG CAP was a  profit-sharing  retirement  plan.
Total   contributions   to  the  WCG  CAP,   including   an   incentive-matching
contribution, totaled $1,605,477 and $3,361,849 for the years ended December 31,
1995 and 1994, respectively.

4.  Income Taxes

At December 31, 1996,  the Company has both  domestic and foreign net  operating
loss  carryforwards.  Domestic  net  operating  loss  carryforwards,  which  are
attributable  to  one  of  the  Company's   subsidiaries,   total  approximately
$2,500,000 and expire in 2010.  Foreign net operating  losses total  $7,245,000,
including  $4,498,000  which carries forward  indefinitely  and $2,747,000 which
expires in 1997 through 2003.

Deferred  income  taxes  reflect  the net tax effects of  temporary  differences
between the carrying  amounts of assets and liabilities for financial  reporting
purposes and the amounts used for income tax purposes and  carryforward  losses.
Significant  components of the Company's  deferred assets and tax liabilities as
of December 31, 1996 and 1995 are as follows:


                                                        1996           1995

                          ======================================================

The Company made income tax payments of $554,199,  $4,472,410  and $4,001,387 in
1996, 1995 and 1994, respectively.

At December  31, 1996,  the Company has not provided for taxes on  undistributed
foreign  earnings of $1,700,308 as the Company  intends to permanently  reinvest
these earnings in the future growth of the business.  Upon distribution of these
earnings in the form of dividends or otherwise,  the Company would be subject to
both U.S. income taxes  (adjusted by foreign tax credits) and withholding  taxes
payable  to the  various  foreign  countries.  Determination  of the  amount  of
unrecognized  deferred U.S. income tax liability is not practical because of the
complexities associated with its calculation;  however, unrecognized foreign tax
credit carryforwards would be available to reduce some portion of the U.S.
liability.

The following  table  reconciles  the amount which would be provided by applying
the 35% federal  statutory  rate to income  before income tax expense to federal
income taxes actually provided:
                                               1996        1995          1994

5.  Available-for-Sale Investments

Management  determines the appropriate  classification of debt securities at the
time of purchase and reevaluates such designation as of each balance sheet date.
Debt  securities  are  classified as  held-to-maturity  when the Company has the
positive intent and ability to hold the securities to maturity. Held-to-maturity
securities are stated at cost. The Company has no held-to-maturity securities at
December 31, 1996 and 1995.

Marketable   equity   securities   and  debt   securities   not   classified  as
held-to-maturity  are  classified  as   available-for-sale.   Available-for-sale
securities are carried at fair value,  with unrealized gains and losses,  net of
tax,  reported as a separate  component of shareholders'  equity.  The amortized
cost of debt  securities  in this  category  is  adjusted  for  amortization  of
premiums and accretion of discounts to maturity.  Such  amortization is included
in  income.  Realized  gains  and  losses  and  declines  in value  judged to be
other-than-temporary  on  available-for-sale  securities are included in income.
The cost of  securities  sold is based on the  specific  identification  method.
Interest and  dividends  on  securities  classified  as  available-for-sale  are
included in investment income.

The following is a summary of available-for-sale investments:

5.  Available-for-Sale Investments (continued)

Gross  realized  gains  on  sales  of   available-for-sale   securities  totaled
approximately $29,500, $5,800 and $0 in 1996, 1995 and 1994,  respectively,  and
gross  realized  losses  totaled   $129,000  and  $250,000  in  1995  and  1994,
respectively.  The change in unrealized  gains and losses on  available-for-sale
securities was a $49,883 gain for the year ended December 31, 1995 and a $51,755
loss for the year ended December 31, 1996.

The  mortgage-backed  securities  mature in the years  2000 and 2001,  but their
expected  maturities  could differ from the contractual  maturities  because the
issuer  of the  security  may  have  the  right to  prepay  obligations  without
prepayment  penalties.  Assuming  the issuers do not exercise  early  prepayment
rights, except for the Company's corporate bond investments whose maturities are
displayed  below,  all other  investments  held by the  Company  will  mature by
December 31, 1997.

                                                        ========================

The  Company,  together  with  three  subsidiaries,  entered  into  a  financing
agreement with certain  lenders and CIT  Group/Business  Credit,  Inc. as agent,
effective  September  23, 1996.  The  agreement is  structured  as a $30 million
revolving  line of credit and a $6 million term loan.  Loans under the revolving
line of credit  automatically  continue until specific  notification  is made by
either  party to the  agreement  on an  anniversary  date,  or in the event of a
default.  In addition,  loans under the revolving  line of credit are limited to
available  collateral,  which  is  generally  defined  as the  sum of 85% of the
Company's  domestic   commercial   accounts  receivable  plus  50%  of  domestic
government accounts receivable.

Proceeds from borrowings under the financing  agreement were used to pay off all
outstanding debt with two commercial banks and one insurance company.

The financing agreement places certain  restrictions on the Company and requires
the Company to comply with certain financial covenants.  The financing agreement
is  secured by  substantially  all the assets of the  Company.  Interest  on the
revolving line of credit is based on various rates available under the financing
agreement  and  selected  by the  Company,  none of which are fixed for a period
greater than six months. At December 31, 1996, the rate was 8.25%.

The Company also  maintains  three  foreign lines of credit which are secured by
assets  of  foreign  subsidiaries  having  a  carrying  value  of  approximately
$15,000,000 at December 31, 1996.  Certain of these foreign lines of credit have
variable interest rates which ranged from 4.75% to 13.25% at December 31, 1996.

9.  Commitments and Contingent Liabilities (continued)

Contract  disputes  and other  claims may arise in  connection  with  government
contracts and subcontracts. A substantial portion of the Company's sales for the
current  year is subject to audit by the Defense  Contract  Audit  Agency.  Such
audits may occur at any time up to three years after  contract  closure.  In the
opinion of the Company's  management,  a provision for government  claims is not
necessary.

Various claims have been made and litigation  instituted  against the Company in
the  ordinary  course  of  business.  In the  opinion  of  management,  adequate
provision  has been made for all known  liabilities  that may result  from these
matters.

The  Company's  GCH  subsidiary  has a bonding  facility of $20 million for each
project and $60 million in the aggregate with United Pacific Insurance  Company.
Additional  amounts are available with United Pacific  Insurance Company subject
to,  among other  things,  review and  acceptance  of final  contract  terms and
confirmation of adequate financing.  At December 31, 1996, GCH had approximately
$43 million available under this bonding program.

10.  Segment and Geographic Information

The  Company  operates  principally  in  one  industry  segment  which  includes
geotechnical,   waste  management  and  environmental  consulting  services  and
construction  contract  services  to  the  remediation  and  civil  construction
industry for on-site pollution control and clean-up.

The Company's  areas of operations are North America,  Asia-Pacific  and Europe.
North American amounts include the Company's operations in Canada and Mexico but

or special proceeding in place of the Constituent Corporations.

                                    ARTICLE 2

                        EFFECT OF MERGER ON CAPITAL STOCK
                         OF THE CONSTITUENT CORPORATIONS

         Section  2.1  Conversion  of the  Woodward-Clyde  Common and  Preferred
Stock.

                  (a) Conversion; Merger Consideration. At the Effective Time of
the  Merger,  each share of the  Woodward-Clyde  Stock  issued  and  outstanding
immediately  prior to the Effective  Time of the Merger shall,  by virtue of the
Merger,  and without any action on the part of the holder thereof,  be converted
as follows:

                          (i) the shares of Woodward-Clyde Preferred Stock shall
         be converted  into the right to receive  $8,306,130 in the aggregate in
         cash,  to be  allocated  between  such  shares in such manner as may be
         determined  by the  trustees  of the  Retirement  Plan (as  defined  in
         Section 8.5 below), all of which shall be payable upon the surrender of
         the certificate(s)  formerly  representing such share of Woodward-Clyde
         Preferred Stock; and

                         (ii) each share of Woodward-Clyde Common Stock shall be
         converted into the right to receive (a) the Applicable  Common Multiple
         (as defined below) of URS Common Stock,  and (b) the Applicable  Common
         Cash  Component  (as  defined  below)  in cash,  all of which  shall be
         payable upon the surrender of the certificate(s)  formerly representing
         such share of Woodward-Clyde Common Stock.

For purposes of this Agreement:

         the "Applicable  Common  Multiple" shall be the multiple:  (A) having a
         numerator  equal to $65 million divided by the average closing price of
         the URS  Common  Stock on the New  York  Stock  Exchange  over the last
         twenty  (20)  trading  days  ending two (2)  trading  days prior to the
         Closing Date (the "URS Average  Closing  Price"),  but in no event less
         than $12.50 or greater than $16.07, and (B) having a denominator equal

                                       4.

<PAGE>

         to the aggregate number of shares of Woodward-Clyde Common Stock issued
         and outstanding  immediately prior to the Effective Time of the Merger;
         and

         The "Applicable Common Cash Component" shall mean the amount determined
         by dividing (A) a numerator equal to $26,693,870,  plus an amount equal
         to the  excess,  if  any,  of  $65  million  over  the  product  of the
         Applicable   Common  Multiple,   the  aggregate  number  of  shares  of
         Woodward-Clyde Common Stock issued and outstanding immediately prior to
         the Effective Time of the Merger and the URS Average  Closing Price, by
         (B)  a  denominator   equal  to  the  aggregate  number  of  shares  of
         Woodward-Clyde Common Stock issued and outstanding immediately prior to
         the Effective Time of the Merger.

         The  cash  and the URS  Common  Stock  so  deliverable  is  hereinafter
collectively referred to as the "Merger Consideration."

                  (b) Fractional  Shares. No fractional shares of the URS Common
Stock will be issued as a result of the Merger.  In lieu of the  issuance of any
fractional   shares  of  the  URS  Common  Stock,   holders  of  shares  of  the
Woodward-Clyde  Stock  who  would  otherwise  have been  entitled  to  receive a
fraction of a share of the URS Common  Stock shall be entitled to receive,  from
URS, an amount of cash, without interest,  equal to the closing price of the URS
Common  Stock as  reported  on the New York Stock  Exchange  on the  trading day
immediately  preceding  the Closing  Date as listed in The Wall Street  Journal,
multiplied  by the  fraction  of a share of the URS  Common  Stock to which such
holder would otherwise have been entitled.

                  (c) Surrender of Certificates and Receipt of Consideration.

                            (1) Appointment of Exchange Agent; Exchange Fund. As
of the Effective  Time of the Merger,  URS shall  deposit,  or shall cause to be
deposited with an exchange agent selected by URS and reasonably  satisfactory to
Woodward-Clyde  (the  "Exchange  Agent"),  for the  benefit  of  holders  of the
Woodward-Clyde  Stock,  for  exchange  in  accordance  with this  Article 2, (i)
certificates  representing the number of shares of the URS Common Stock issuable
as part of the  Merger  Consideration,  and (ii) cash in an amount  equal to the
aggregate cash component of the Merger Consideration,  and (iii) cash to be paid
in lieu of the issuance of fractional shares (such cash and certificates for the
shares of URS Common  Stock are  hereinafter  referred  to  collectively  as the
"Exchange Fund").

                            (2) Notice to Woodward-Clyde  Stockholders.  As soon
as  reasonably  practicable  after the Effective  Time of the Merger,  URS shall
cause the Exchange

                                       5.

<PAGE>

Agent  to mail  to each  holder  of  record  of a  certificate  or  certificates
representing the  Woodward-Clyde  Stock (A) a letter of transmittal  which shall
specify  that  delivery  shall be  effected,  and risk of loss and  title to the
certificates  for  shares of the  Woodward-Clyde  Stock  shall  pass,  only upon
delivery of the certificates for the shares of the  Woodward-Clyde  Stock to the
Exchange Agent,  and shall be in such form and have such other provisions as URS
may reasonably specify,  and (B) instructions for use in effecting the surrender
of the certificates for the shares of the  Woodward-Clyde  Stock in exchange for
the Merger Consideration.

                            (3) Surrender of Woodward-Clyde  Stock Certificates.
Upon  surrender  of a  certificate  for  shares of the  Woodward-Clyde  Stock (a
"Woodward-Clyde Stock Certificate") for cancellation to the Exchange Agent or to
such other agent or agents as may be appointed by URS, together with such letter
of transmittal,  duly executed and completed in accordance with the instructions
thereto,  the holder  thereof shall be entitled to receive in exchange  therefor
the number of whole  shares of the URS  Common  Stock to which the holder of the
Woodward-Clyde Stock is entitled pursuant to this Article 2 plus that portion of
the cash in the  Exchange  Fund  which  such  holder  has the  right to  receive
pursuant to the  provisions  of this  Section 2.1,  after  giving  effect to any
required  withholding  tax, and the  Woodward-Clyde  Stock  Certificate  for the
shares of the Woodward-Clyde Stock so surrendered shall forthwith be canceled.

                            (4) Limitations. Notwithstanding any other provision
of  this  Agreement,   until  holders  of  Woodward-Clyde   Stock   Certificates
representing  shares  of the  Woodward-Clyde  Stock  have  surrendered  them for
exchange as provided herein,  (1) no dividends or other  distributions  shall be
paid with respect to any shares  represented by such Certificates and no payment
for  fractional  shares  shall be made,  and (2)  without  regard  to when  such
Woodward-Clyde  Stock  Certificates  are  surrendered  for  exchange as provided
herein, no interest shall be paid on any dividends or other distributions or any
payment  for  fractional  shares.  Upon  surrender  of  a  Woodward-Clyde  Stock
Certificate,  there  shall be paid to the  holder of such  Woodward-Clyde  Stock
Certificate the amount of any dividends or other distributions which theretofore
became  payable,  but which were not paid by reason of the  preceding  sentence,
with respect to the number of whole shares of URS Common  Stock  represented  by
the Woodward-Clyde Stock Certificate or Certificates issued upon such surrender.
If any  certificate for URS Common Stock is to be issued in a name other than in
which the Woodward-Clyde  Stock Certificate  surrendered in exchange therefor is
registered,  it shall be a condition of such exchange that the person requesting
such exchange pay any transfer or other taxes required by reason of the issuance
of certificates for such shares of URS Common Stock in a name other than that of
the registered holder of the Woodward-Clyde  Stock Certificate  surrendered,  or
establish to the satisfaction of Woodward-Clyde that

                                       6.

<PAGE>

such tax has been paid or is not  applicable.  Certificates  of URS Common Stock
issued  to  holders  of  Woodward-Clyde  Stock  issued  under  a  Woodward-Clyde
restricted  stock plan shall bear legends  substantially  similar to the legends
presently on the Woodward-Clyde Stock Certificates and as required by applicable
law.

                            (5) Payment. The Exchange Agent shall within fifteen
(15) business days of receipt of such  Woodward-Clyde  Stock Certificate pay the
holder of such certificate,  in immediately  available funds, the amount of cash
into which the shares  theretofore  represented by such  certificate  shall have
been converted pursuant to Section 2.1, and the Woodward-Clyde Stock Certificate
so  surrendered  shall be  canceled.  In the event of a transfer of ownership of
shares of Woodward-Clyde Stock that is not registered in the transfer records of
Woodward-Clyde,  payment may be made to a person  other than the person in whose
name the certificate so surrendered is registered,  if such certificate shall be
properly  endorsed or  otherwise  be in proper form for  transfer and the person
requesting such payment shall pay any transfer or other taxes required by reason
of  the  payment  to  a  person  other  than  the  registered   holder  of  such
Woodward-Clyde  Stock  Certificate  or  establish  to  the  satisfaction  of the
Woodward-Clyde  that  such  tax  has  been  paid  or is  not  applicable.  Until
surrendered  as  contemplated  by this Section 2.1,  each  Woodward-Clyde  Stock
Certificate  shall be deemed at any time after the Effective  Time of the Merger
to  represent  only the right to receive upon such  surrender  the amount of the
Merger  Consideration,  without  interest,  into  which the  shares  theretofore
represented by such Woodward-Clyde Stock Certificate shall be converted pursuant
to this Section 2.1. No interest will be paid or will accrue on the cash payable
upon the surrender of any Woodward-Clyde Stock Certificate.

                  (d) Cancellation of the Woodward-Clyde Stock; Closing of Stock
Transfer Books.  At the Effective Time of the Merger,  all of the authorized and
outstanding  shares of the  Woodward-Clyde  Stock shall be canceled and cease to
represent  any interest in  Woodward-Clyde  and such holders shall cease to have
any rights of a  stockholder  of  Woodward-Clyde.  The stock  transfer  books of
Woodward-Clyde  shall be  closed at the  Effective  Time of the  Merger,  and no
further  transfers of  Woodward-Clyde  Stock will be made on such stock transfer
books. From and after the Effective Time of the Merger, the holders of shares of
the Woodward-Clyde Stock outstanding  immediately prior to the Effective Time of
the  Merger  as such  holders  shall be  entitled  to  receive  only the  Merger
Consideration.  From the Effective Time of the Merger, the holders of the shares
of the  Woodward-Clyde  Stock which shall be converted into the URS Common Stock
pursuant to Section 2.1(a) shall have all of the rights of holders of the number
of shares of the URS Common Stock into which such Woodward-Clyde  Stock has been
converted.

         Section  2.2  Dissenting  Shares.   Notwithstanding  anything  in  this
Agreement to the contrary,  shares of  Woodward-Clyde  Stock that are issued and
outstanding  immediately  prior to the Effective Time of the Merger and that are
held by  stockholders  who have not voted such shares in favor of the Merger and
who have  delivered a written  demand for appraisal of such shares in the manner
provided in Section 262 of the Delaware Law  ("Dissenting  Shares") shall not be
canceled  and  converted  into  shares of URS Common  Stock in  accordance  with
Section 2.1 above unless and until such holder shall have failed to perfect,  or
shall have  effectively  withdrawn or lost, such holder's right to appraisal and
payment  under the  Delaware  Law. If such  stockholder  shall have so failed to
perfect,  or shall have effectively  withdrawn or lost such right, such holder's
shares of  Woodward-Clyde  Stock shall thereupon be deemed to have been canceled
and converted as described in Section 2.1 at the  Effective  Time of the Merger,
and each such share shall  represent  solely the right to receive  shares of URS
Common Stock and cash in accordance with Section 2.1.  Woodward-Clyde shall give
URS prompt notice of any demands received by Woodward-Clyde for appraisal of its
shares, and, prior to the Effective Time of the Merger, URS shall have the right
to participate in all negotiations and proceedings with respect to such demands.
Prior to the Effective Time of the Merger, Woodward-Clyde shall not, except with
the prior written consent of URS, make any payment with respect to, or settle or
offer to settle,  any such  demands.  From and after the  Effective  Time of the
Merger,  no stockholder of Woodward-Clyde  who has demanded  appraisal rights as
provided in Section  262(d) of the  Delaware  Law shall be entitled to vote such
holder's shares of Woodward-Clyde Stock for any purpose or to receive payment of
dividends or other  distributions  with respect to such holder's  shares (except
dividends and other  distributions  payable to  stockholders of record at a date
which is prior to the Effective Time of the Merger).

         Section 2.3  Subsidiary  Common  Stock.  At the  Effective  Time of the
Merger, each share of the Subsidiary Common Stock outstanding  immediately prior
to the Effective Time of the Merger shall remain issued and outstanding.

         Section 2.4 Cancellation of Treasury Shares. Any share of the Woodward-
Clyde Stock held in the treasury of  Woodward-Clyde at the Effective Time of the
Merger shall be canceled and retired at the Effective  Time of the Merger and no
shares shall be issuable with respect thereto.

         Section 2.5  Withholding  Tax. The right of any  stockholder to receive
the Merger  Consideration  shall be subject to and  reduced by the amount of any
required tax withholding obligation.

                                       8.

                REPRESENTATIONS AND WARRANTIES OF WOODWARD-CLYDE

         Except as otherwise  disclosed to URS in a letter delivered to it prior
to the execution  hereof (which letter shall contain  appropriate  references to
identify the  representations  and warranties herein to which the information in
such letter relates) (the "Woodward-Clyde  Disclosure  Letter"),  Woodward-Clyde
represents and warrants to URS and the Subsidiary as follows:

         Section 4.1 Organization. Each of Woodward-Clyde and the Woodward-Clyde
Subsidiaries (as hereinafter  defined) is a corporation duly organized,  validly
existing,  and in  good  standing  under  the  laws of the  jurisdiction  of its
incorporation and has all requisite corporate power and authority to own, lease,
and operate its properties, and to carry on its business as now being conducted,
except where the failure to be so organized,  existing,  and in good standing or
to have  such  power and  authority  would  not have a  Woodward-Clyde  Material
Adverse  Effect (as defined  below).  Each of  Woodward-Clyde  and the Woodward-
Clyde  Subsidiaries  is duly  qualified or licensed  and in good  standing to do
business in each  jurisdiction in which the property owned,  leased, or operated
by it or the nature of the  business  conducted  by it makes such  qualification
necessary,  except in any such  jurisdictions  where the  failure  to be so duly
qualified  or  licensed  and in good  standing  would not have a  Woodward-Clyde
Material  Adverse Effect (defined  below).  For purposes of this Agreement:  (a)
"Woodward-Clyde  Material  Adverse  Effect" means,  when used in connection with
Woodward-Clyde, any change or effect that is materially adverse to the business,
financial condition,  results of operations, or assets of Woodward-Clyde and the
Woodward-Clyde  Subsidiaries  taken as a whole,  other  than  changes or effects
resulting from (i) changes

                                       9.

<PAGE>

attributable to conditions  affecting the engineering  business generally,  (ii)
changes in general  economic  conditions,  or (iii) changes  attributable to the
announcement or pendency of the Merger.

         Section  4.2   Capitalization.   The   authorized   capital   stock  of
Woodward-Clyde  consists of 4,922,625 shares of Woodward-Clyde Common Stock, par
value $0.01 per share, and 77,375 shares of preferred stock, par value $0.01 per
share  (the  "Woodward-Clyde  Preferred  Stock").  As of the  date  hereof,  (i)
1,964,175 shares of Woodward-Clyde Common Stock are issued and outstanding, (ii)
no shares of  Woodward-Clyde  Common  Stock are held in  treasury,  (iii) 44,898
shares of  Woodward-Clyde  Preferred Stock are issued and outstanding,  and (iv)
32,477 shares of Woodward-Clyde Preferred Stock are held in treasury. All of the
issued and outstanding shares of Woodward-Clyde  Stock are validly issued, fully
paid and nonassessable and free of preemptive rights.  Except as set forth above
or as specified  in Section 4.2 of the  Woodward-Clyde  Disclosure  Letter or as
disclosed in the notes to the Woodward-Clyde Financial Statements (as defined in
Section 4.7 below) for the period ended  December  31,  1996,  as of the date of
this Agreement there are no shares of Woodward-Clyde  capital stock of any other
class issued or  outstanding  or any options,  warrants,  subscriptions,  calls,
rights,  convertible  securities or other  agreements or commitments  obligating
Woodward-Clyde to issue, transfer, sell, redeem, repurchase or otherwise acquire
any  shares of its  capital  stock or  securities.  Except as  provided  in this
Agreement  or as set  forth  in  Section  4.2 of the  Woodward-Clyde  Disclosure
Letter,  after the  Effective  Time of the Merger,  Woodward-Clyde  will have no
obligation to issue,  transfer or sell any shares of its capital stock  pursuant
to any employee benefit plan or otherwise.

         Section 4.3 Subsidiaries.  Section 4.3 of the Woodward-Clyde Disclosure
Letter  identifies  each  corporation  or other entity of which  Woodward-Clyde,
directly or indirectly,  owns or controls  voting  securities or other interests
which are  sufficient  to elect a majority of the board of  directors  or others
performing   similar   functions  of  such   corporation   or  other  entity  (a
"Woodward-Clyde  Subsidiary") and sets forth for each Woodward-Clyde Subsidiary:
(i) its  name  and  jurisdiction  of  incorporation  or  organization;  (ii) its
authorized  capital stock; and (iii) the number of issued and outstanding shares
of  capital  stock.  Woodward-Clyde  owns  directly  or  indirectly  each of the
outstanding  shares of capital  stock (or other  ownership  interests  having by
their terms  ordinary  voting  power to elect a majority of  directors or others
performing similar functions with respect to such Woodward-Clyde  Subsidiary) of
each of the  Woodward-Clyde  Subsidiaries.  Each of the  outstanding  shares  of
capital stock of each of the  Woodward-Clyde  Subsidiaries  is duly  authorized,
validly issued, fully paid and nonassessable.  Each of the outstanding shares of
capital  stock  of  each  Woodward-Clyde   Subsidiary  is  owned,   directly  or
indirectly,  by Woodward-Clyde,  free and clear of all liens, pledges,  security
interests, claims, or other encumbrances of any nature

                                       10.

whatsoever  ("Liens").  There are not now, and at Closing there will not be, (a)
any issued or outstanding  securities  convertible into or exchangeable  for, or
any options,  warrants,  calls,  subscriptions  or other rights  (preemptive  or
otherwise) to acquire,  any shares of capital stock of any of the Woodward-Clyde
Subsidiaries;  or (b)  any  agreements  or  contractual  commitments  obligating
Woodward-Clyde,  or restricting  Woodward-Clyde's  rights, to transfer, sell, or
vote, the capital stock of the Woodward-Clyde Subsidiaries owned by it, directly
or indirectly.

         Section 4.4 Material Investments. Except as set forth in Section 4.4 of
the  Woodward-Clyde  Disclosure  Letter,  Woodward-Clyde  does not  directly  or
indirectly  own any equity or similar  interest in, or any interest  convertible
into or exchangeable  or exercisable for any equity or similar  interest in, any
corporation (other than a Woodward-Clyde Subsidiary), partnership, joint venture
or other business association or entity that is material to Woodward-Clyde. With
respect  to  those  entities  indicated  on  Section  4.4 of the  Woodward-Clyde
Disclosure  Letter,  Woodward-Clyde  has  heretofore  delivered to URS financial
statements  (audited to the extent  available) and interim  unaudited  financial
statements of each of such entities (through the most recently  concluded fiscal
quarter for each of such persons) and, to the best knowledge of  Woodward-Clyde,
such financial  statements fairly present, in conformity with generally accepted
accounting  principles  ("GAAP") applied on a consistent basis (except as may be
indicated  in  the  notes  thereto  or in  Section  4.4  of  the  Woodward-Clyde
Disclosure  Letter),  the  financial  condition  of each  thereof  as at and the
results of operations for the periods so indicated  (subject to normal  year-end
adjustments  in the case of the interim  unaudited  financial  statements),  and
Woodward-Clyde's  disclosures  with  respect  to its  investment  in  each  such
entities otherwise included in the Woodward-Clyde  Reports (as defined below) do
not contain any untrue statements of material fact or omit to state any material
fact  required to be stated  therein or which are necessary in order to make the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading.  Except  as set  forth  in  Section  4.4 of the  Woodward-Clyde
Disclosure  Letter,  Woodward-Clyde  (or, as indicated thereon, a Woodward-Clyde
Subsidiary)  has good and  marketable  title to the  securities  evidencing  its
investment  in the  entities  indicated  in  Section  4.4 of the  Woodward-Clyde
Disclosure  Letter,  and such  securities have been validly issued and are fully

financial  report  delivered to its lenders,  and each proxy statement or annual
information  statement,  including,  without  limitation,  its Annual Reports to
Stockholders,  delivered to its stockholders,  at any time since January 1, 1992

Woodward-Clyde  Reports, each of the Woodward-Clyde  Reports did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the  circumstances  under which they were made, not  misleading.  Each of the

the Woodward-Clyde  Subsidiaries as of its date and the consolidated  results of
operations and cash flows for the period then ended (subject to normal  year-end

together with the Form S-4, the "Proxy  Statement/Form  S-4"),  will: (i) in the
case of the Proxy Statement and any amendment or supplement thereto,  (1) at the

(z) at the time of the meeting of the  stockholders of  Woodward-Clyde,  contain
any untrue  statement  of a  material  fact or omit to state any  material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading. Woodward-Clyde agrees to correct as promptly as practicable any such
information  provided by it that shall have become  false or  misleading  in any
material  respect and to take all steps necessary to enable URS to file with the
SEC  and  have  declared  effective  or  cleared  by the SEC  any  amendment  or
supplement  to the Proxy  Statement  so as to correct  the same and to cause the
Proxy Statement as so corrected to be disseminated to the Woodward-Clyde and URS

other  acquisition of any shares of its capital  stock,  (c) any increase in the
regular  compensation of any of the officers or employees of  Woodward-Clyde  or

(which shall include normal periodic performance reviews, promotions and related
compensation  increases),  (d)  any  incurrence,   assumption  or  guarantee  by
Woodward-Clyde or any of the Woodward-Clyde Subsidiaries of any indebtedness for
borrowed  money other than in the ordinary  course of business  consistent  with
past  practices,  (e) any  transaction  or  commitment  made, or any contract or
agreement  entered  into,  by  Woodward-Clyde  or  any  of  the   Woodward-Clyde
Subsidiaries  (including  the  acquisition  or disposition of any assets) or any
relinquishment by Woodward-Clyde  or any of the  Woodward-Clyde  Subsidiaries of
any  contract or other  right,  in either  case,  material  to  Woodward-Clyde's
business  taken as a whole,  other  than  transactions  and  commitments  in the
ordinary   course  of  business   consistent   with  past  practices  and  those
contemplated  by this  Agreement,  (f) any change in any method of accounting or
accounting practice by Woodward-Clyde or any of the Woodward-Clyde Subsidiaries,
except  for any such  change  after  the date  hereof  required  by  reason of a
mandatory concurrent change in GAAP, (g) any loss or damage to the properties or
assets of Woodward-Clyde or the  Woodward-Clyde  Subsidiaries which has resulted
or is reasonably  likely to result in a Woodward-Clyde  Material Adverse Effect,

this Section 4.9.

         Section 4.10 Litigation.  Except for litigation  disclosed in the notes
to the financial  statements  included in the  Woodward-Clyde  Reports or as set
forth in Section 4.10 of the Woodward-Clyde Disclosure Letter, there is no suit,
action or proceeding (whether at law or equity, before or by any Federal,  state
or foreign court,  tribunal,  commission,  board, agency or instrumentality,  or
before any  arbitrator)  pending or, to the best  knowledge  of  Woodward-Clyde,
threatened  against or  affecting  Woodward-Clyde  or any of the  Woodward-Clyde
Subsidiaries,   the   outcome  of  which,   in  the   reasonable   judgment   of
Woodward-Clyde,   is  likely   individually  or  in  the  aggregate  to  have  a
Woodward-Clyde Material Adverse Effect, or which challenges the validity of this
Agreement or seeks to prevent, enjoin,  materially alter or materially delay the
transactions contemplated hereby, nor is there any judgment, decree, injunction,
rule  or  order  of any  court,  governmental  department,  commission,  agency,
instrumentality or arbitrator  outstanding against  Woodward-Clyde or any of the
Woodward-Clyde  Subsidiaries  having,  or which,  insofar as can  reasonably  be
foreseen, in the future may have, any such effect.

                                       15.

         Section 4.11 Absence of Undisclosed Liabilities. Except for liabilities
or  obligations  which are  accrued or  reserved  against in the  Woodward-Clyde
Financial  Statements (or reflected in the notes thereto) or which were incurred
after December 31, 1996 in the ordinary  course of business and consistent  with
past  practices or in  connection  with the  transactions  contemplated  by this
Agreement,  Woodward-Clyde and the  Woodward-Clyde  Subsidiaries do not have any
liabilities or obligations (whether absolute,  accrued, contingent or otherwise)
of a nature required by GAAP to be reflected in a consolidated balance sheet (or
reflected in the notes thereto).

         Section  4.12 No  Default.  Except as set forth in Section  4.12 of the
Woodward-Clyde   Disclosure  Letter,  neither  Woodward-Clyde  nor  any  of  the
Woodward-Clyde  Subsidiaries is in violation or breach of, or default under (and
to the best knowledge of  Woodward-Clyde no event has occurred which with notice
or the lapse of time or both  would  constitute  a  violation  or breach  of, or
default  under) any term,  condition  or  provision  of (a) its  Certificate  or
Articles of  Incorporation,  as the case may be, or Bylaws,  (b) any note, bond,
mortgage,  deed of  trust,  security  interest,  indenture,  license,  contract,

registration,  license,  permit and other  consent or approval  of  governmental
agencies or accreditation  organization,  except in the case of clauses (b), (c)

or in the aggregate have a Woodward-Clyde Material Adverse Effect.

Woodward-Clyde  Subsidiaries own all of their tangible and intangible  property,
real and personal,  free and clear of any Liens, except for statutory mechanics'
and materialmens'  liens, liens for current taxes not yet delinquent,  and liens
and encumbrances which do not confer upon the secured parties rights to property

Woodward-Clyde or the  Woodward-Clyde  Subsidiaries and used in the operation of
their business are in satisfactory  condition and repair for the requirements of
such  business as presently  conducted.  Neither  Woodward-Clyde  nor any of the

leased by Woodward-Clyde or any of the Woodward-Clyde Subsidiaries.

         Section 4.15 Benefit Plans.

                  (a) Section 4.15 of the Woodward-Clyde Disclosure Letter lists
each  Woodward-Clyde  Plan  (as  defined  below).  With  respect  to each of the
Woodward-Clyde Plans,  Woodward-Clyde has heretofore delivered or made available
to URS true and complete copies of each of the following  documents:  (i) a copy
of each written plan (including all amendments thereto) or a description of each
unwritten plan; (ii) a copy of the annual report,  if required under ERISA, with
respect to each  Woodward-Clyde  Plan for the last three years;  (iii) a copy of
the  actuarial   report,   if  required  under  ERISA,   with  respect  to  each
Woodward-Clyde  Plan for the last three years and any interim  actuarial reports
or calculations provided by the actuary since the date of the most recent annual
actuarial  report;  (iv)  the  most  recent  summary  plan  description  and all
succeeding summaries of material  modifications for each Woodward-Clyde Plan for
which a summary plan description is required;  (v) if the Woodward-Clyde Plan is

or other funding  agreement  (including all  amendments  thereto) and the latest
financial  statements  thereof;  and (vi) the most recent  determination  letter
issued with respect to each Qualified Woodward-Clyde Plan. Each of the Woodward-
Clyde Plans has been  operated  and  administered  in all  material  respects in
accordance with their terms and with all applicable laws,  including Federal and
state securities laws. Each  Woodward-Clyde  Plan intended to be qualified under
Section  401(a)  of the  Code is so  qualified  and  has  received  a  favorable
determination  letter from the  Internal  Revenue  Service  with respect to such
qualification,  its related trust has been determined to be exempt from taxation
under Section 501(a) of the Code and nothing has occurred since the date of such
letter that would adversely affect such qualification or exemption.

                  (b) Section 4.15 of the Woodward-Clyde Disclosure Letter lists
each  Woodward-Clyde  Benefit  Arrangement  which  provides,  or is  expected to
provide,  for aggregate  payments of in excess of $100,000 in any calendar year.
With respect to each of

                                       18.

<PAGE>

the Woodward-Clyde Benefit Arrangements, Woodward-Clyde has heretofore delivered
to or made  available  to URS true and  complete  copies  of each  written  plan
(including all amendments thereto) or a description of each unwritten plan. Each
Woodward-Clyde Benefit Arrangement has been maintained in substantial compliance
with its terms and with the  requirements  prescribed  by any and all  statutes,
orders,  rules, and regulations,  including,  without limitation,  ERISA and the
Code, that are applicable to such Woodward-Clyde Benefit Arrangement,  including
Federal and state securities laws.

                  (c) Neither Woodward-Clyde nor the Woodward-Clyde Subsidiaries
nor any of their ERISA  Affiliates has been involved in any  transaction,  taken
any action,  or failed to take any action relating to a  Woodward-Clyde  Benefit
Arrangement that could cause  Woodward-Clyde or the Woodward-Clyde  Subsidiaries
to be subject to any liability that would likely cause a Woodward-Clyde Material
Adverse  Effect.  No  fiduciary  of any  Woodward-Clyde  Plan or  Woodward-Clyde
Benefit  Arrangement  has taken any action that would  result in such  fiduciary
being liable for the payment of damages  under ERISA  Section 409 and that would
result  in  any  material  liability  for  Woodward-Clyde,   the  Woodward-Clyde
Subsidiaries or URS.

                  (d) Except with  respect to  contributions  to  Woodward-Clyde
Plans under  Section 412 of the Code that are current and not past due,  neither
Woodward-Clyde  nor the  Woodward-Clyde  Subsidiaries has incurred  (directly or
indirectly) prior to the Closing any current obligation to pay (i) any liability
under Title IV of ERISA or (ii) any liability under Section 412 of the Code that
remains unpaid at the date of signing of this  Agreement.  There is no "unfunded
pension  liability,"  i.e.,  excess of the value of benefits earned to date over
assets, with respect to Employee Benefit Plans subject to Title IV of ERISA. All
premiums owed to the Pension Benefit  Guaranty  Corporation  with respect to any
Employee Benefit Plan subject to Title IV have been paid.

                  (e) None of Woodward-Clyde,  the Woodward-Clyde  Subsidiaries,
or  their  ERISA  Affiliates  is  making  or  accruing  an  obligation  to  make
contributions or has, on or after January 1, 1980, made or accrued an obligation
to make contributions to a "multiemployer plan" as defined in Section 4001(a)(3)
of ERISA.

                  (f)  Full   payment  has  been  made  of  all   amounts   that
Woodward-Clyde  and  the  Woodward-Clyde  Subsidiaries  are  required  to pay as
contributions  to the  Employee  Benefit  Plans  as of the  last day of the most
recent  fiscal  year  of each  of the  plans  ended  prior  to the  date of this
Agreement.

                                       19.

<PAGE>

                  (g)  No   Woodward-Clyde   Plan  or   Woodward-Clyde   Benefit
Arrangement  provides or ever provided benefits,  including without  limitation,
death or medical  benefits  (whether or not insured and whether or not  funded),
with  respect  to  current  or  former  employees  of  Woodward-Clyde   and  the
Woodward-Clyde  Subsidiaries  beyond their  retirement or other  termination  of
service  (other  than (i)  coverage  mandated  by  applicable  law,  (ii)  death
benefits,  or retirement  benefits under any "employee pension benefit plan," as
that term is defined  in  Section  3(2) of ERISA,  (iii)  deferred  compensation
benefits  accrued as  liabilities on the books of  Woodward-Clyde  and disclosed
heretofore  to URS,  or (iv)  benefits  the full  cost of which are borne by the
current or former employee (or his or her beneficiary)). The consummation of the
transactions  contemplated  hereby  will not (i)  entitle  any current or former
employee of Woodward-Clyde or the Woodward-Clyde  Subsidiaries to severance pay,
unemployment compensation or any similar payment, or (ii) accelerate the time of
payment or vesting,  or increase the amount of any  compensation due to any such
employee or former employee.

                  (h) With respect to  Woodward-Clyde  Plans and  Woodward-Clyde
Benefit  Arrangements,  all reports,  forms, and other documents  required to be
filed  with any  governmental  authority  or  distributed  to plan  participants
(including,  without  limitation,  summary plan  descriptions,  Forms 5500,  and
summary annual  reports) have been timely filed (if  applicable) and distributed
(if applicable) and were accurate.

                  (i) There are no pending,  threatened,  or anticipated  claims
(other  than  routine  claims for  benefits)  by, on behalf  of, or against  any
Woodward-Clyde Plans or Woodward-Clyde  Benefit Arrangements.  No Woodward-Clyde
Plans or  Woodward-Clyde  Benefit  Arrangements  are  presently  under  audit or
examination  (nor has notice been received of a potential audit) by the Internal
Revenue  Service,  the  Department of Labor,  or PBGC, nor are there any matters
pending  with  respect  to any  Woodward-Clyde  Plan with the  Internal  Revenue

agency or commission or other governmental authority or instrumentality, whether
domestic or foreign (each a "Governmental  Entity") applicable to Woodward-Clyde
or any Woodward-Clyde  Subsidiary,  except for such violations, if any, that, in

transactions  contemplated  hereby  or  thereby,  and the loss of  which  would,

their terms and none of Woodward-Clyde or the  Woodward-Clyde  Subsidiaries nor,
to the knowledge of Woodward-Clyde, any other party thereto, is in default under
any of such agreements,  nor, to the knowledge of Woodward-Clyde,  has any event

constitute  any  event  of  default  by  Woodward-Clyde  or  the  Woodward-Clyde
Subsidiaries  or any other party  thereto  other than with respect to any of the
foregoing  such  defaults,  if  any,  that  would  not,  individually  or in the
aggregate,  have a Woodward-Clyde  Material Adverse Effect. To  Woodward-Clyde's
knowledge,  none of the parties to the contracts identified in this Section have
terminated,  or have  expressed  an  intent to reduce  materially  or  terminate
presently or in the future, such contracts.

Woodward-Clyde  in this  Agreement,  the  schedules  hereto or any  certificates
delivered  pursuant  to the terms  hereof,  contains  or will  contain an untrue

necessary to make the statements  contained  herein or therein,  in light of the
circumstances in which they were made, not misleading.

made by  Woodward-Clyde  with the knowledge and expectation  that URS is placing
reliance thereon.

         Section  5.1  Organization.  Each  of  URS  and  the  Subsidiary  is  a
corporation  duly organized,  validly  existing,  and in good standing under the
laws of the jurisdiction of its  incorporation  and has all requisite  corporate
power and authority to own, lease,  and operate its properties,  and to carry on
its  business  as  now  being  conducted,  except  where  the  failure  to be so
organized,  existing,  and in good  standing or to have such power and authority
would not have a URS Material Adverse Effect.  Each of URS and the Subsidiary is
duly  qualified  or  licensed  and in  good  standing  to do  business  in  each
jurisdiction  in which the  property  owned,  leased,  or  operated by it or the
nature of the  business  conducted  by it makes  such  qualification  necessary,
except in any such  jurisdictions  where the failure to be so duly  qualified or
licensed and in good standing would not have a URS Material Adverse Effect.  For
purposes of this Agreement,  "URS Material  Adverse Effect" means,  when used in
connection  with URS,  any change or effect  that is  materially  adverse to the
business,  financial  condition,  results of operations or assets of URS and its
Subsidiaries  taken as a whole, other than changes or effects resulting from (i)
changes attributable to conditions affecting the engineering business generally,
(ii) changes in general economic  conditions,  or (iii) changes  attributable to
the announcement or pendency of the Merger.

         Section  5.2  Capitalization.  The  authorized  capital  stock  of  URS
consists of 20,000,000  shares of URS Common  Stock,  par value $0.01 per share,
and  1,000,000  shares of preferred  stock,  par value $1.00 per share (the "URS
Preferred  Stock").  As of the date hereof,  (i) 10,561,263 shares of URS Common
Stock are issued and  outstanding,  (ii) options to acquire  1,623,938 shares of
URS Common Stock are outstanding  under all stock option plans and agreements of
URS, (iii) 2,463,043 shares of URS Common Stock (including  shares of URS Common
Stock issuable upon exercise of the options identified in clause (ii) above) are
reserved  for issuance  pursuant to all employee and director  plans of URS, and
(iv) there are no shares of URS Preferred Stock  outstanding.  All of the issued
and outstanding  shares of URS Common Stock are validly  issued,  fully paid and
nonassessable  and free of  preemptive  rights,  and are  listed on the New York
Stock  Exchange and the Pacific  Exchange.  All of the URS Common Stock reserved
for  issuance  in  exchange  for the shares of the  Woodward-Clyde  Stock at the
Effective Time of the Merger in accordance  with this Agreement will be, when so
issued, duly authorized,  validly issued,  fully paid and nonassessable and free
of  preemptive  rights,  and are listed on the New York Stock  Exchange  and the
Pacific Exchange. The authorized capital stock of the Subsidiary consists of 100
shares of the Subsidiary  Common Stock,  par value $1.00 per share, all of which
shares are validly issued and outstanding,  fully paid and nonassessable and are
owned by URS.  Except as set forth above or as  specified  in Section 5.2 of the
URS Disclosure  Letter,  as of the date of this Agreement there are no shares of
capital  stock  of  URS  issued  or  outstanding   or  any  options,   warrants,

commitments  obligating  URS to issue,  transfer,  sell,  redeem,  repurchase or
otherwise acquire

                                       31.

any  shares of its  capital  stock or  securities.  Except as  provided  in this
Agreement or as set forth in Section 5.2 of the URS Disclosure Letter, after the
Effective Time of the Merger, URS will have no obligation to issue,  transfer or
sell any shares of its capital  stock  pursuant to any employee  benefit plan or
otherwise.

         Section 5.3 Authority  Relative to this Agreement.  Each of URS and the
Subsidiary  has all requisite  corporate  power and authority to enter into this
Agreement  and  subject,  in the case of this  Agreement,  to the  consents  and
approvals  set forth in  Section  5.4  below,  to  consummate  the  transactions
contemplated  hereby. The execution,  delivery and performance of this Agreement
by URS and the Subsidiary and the  consummation by URS and the Subsidiary of the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate action on the part of URS and the Subsidiary,  including the unanimous
approval  of their  respective  Boards  of  Directors,  and no  other  corporate
proceedings on the part of URS or the Subsidiary are necessary to authorize this
Agreement or the transactions  contemplated hereby. This Agreement has been duly
and validly  executed and delivered by URS and the Subsidiary and  constitutes a
valid and binding agreement of each of them, enforceable against each of them in
accordance with its terms, except that such enforceability may be subject to (i)
bankruptcy,  insolvency,  reorganization  or  other  similar  laws  relating  to
enforcement  of  creditors'  rights   generally,   and  (ii)  general  equitable
principles.

         Section 5.4  Consents  and  Approvals;  No  Violations.  Except for the
applicable  requirements of the Governmental  Requirements,  state securities or
blue sky laws, state and local laws and regulations  relating to licensing,  and
the filing of the Documents of Merger as required by the Delaware Law, no filing
with,  and no permit,  authorization,  consent or  approval  of, any  Government
Entity  is  necessary  for  the  execution,  delivery  and  performance  of this
Agreement  by URS and the  Subsidiary  or for  the  consummation  by URS and the
Subsidiary  of the  transactions  contemplated  by this  Agreement.  Neither the
execution, delivery nor performance of this Agreement by URS and the Subsidiary,
nor the consummation by URS and the Subsidiary of the transactions  contemplated
hereby,  nor  compliance by URS and the  Subsidiary  with any of the  provisions
hereof,  will (i) conflict with or result in any breach of any provisions of the
Certificate of Incorporation or By-Laws of URS or the Subsidiary or the Articles
or  Certificate of  Incorporation,  as the case may be, or By-Laws of any of the
URS  Subsidiaries,  (ii)  except  as set  forth in  Section  5.4(ii)  of the URS
Disclosure  Letter,  result in a violation or breach of, or constitute  (with or
without  due  notice  or lapse of time or both) a  default  (or give rise to any
right of termination,  cancellation,  acceleration,  vesting, payment, exercise,
suspension or revocation)  under, any of the terms,  conditions or provisions of
any note, bond, mortgage, deed of trust, security interest,  indenture, license,
contract,  agreement, plan or other instrument or obligation to which URS or any
of the URS Subsidiaries is a party or by which any of them or any of

in Section  5.4(iii) of the URS  Disclosure  Letter,  violate  any order,  writ,
injunction,  decree,  statute,  rule or  regulation  applicable  to URS, any URS
Subsidiary  or any of their  properties  or assets,  (iv) except as set forth in
Section  5.4(iv)  of the  URS  Disclosure  Letter,  result  in the  creation  or
imposition of any Lien on any asset of URS or any URS Subsidiary,  or (v) except
as set  forth  in  Section  5.4(v)  of the  URS  Disclosure  Letter,  cause  the
suspension   or  revocation  of  any   certificates   of  need,   accreditation,
registrations, licenses, permits and other consents or approvals of governmental
agencies or  accreditation  organizations,  except in the case of clauses  (ii),
(iii),  (iv)  and  (v)  for  violations,   breaches,   defaults,   terminations,
cancellations, accelerations, creations, impositions, suspensions or revocations
which would not  individually  or in the aggregate  have a URS Material  Adverse
Effect.

         Section 5.5 URS SEC Reports and Financial Statements. URS has delivered
to  Woodward-Clyde  true and  complete  copies of each  registration  statement,
report and proxy or information statement,  including,  without limitation,  its
Annual  Reports to  Stockholders  incorporated  in material part by reference in
certain of such  reports,  in the form  (including  exhibits and any  amendments
thereto) required to be filed with SEC since January 1, 1992 (collectively,  the
"URS SEC  Reports").  Except as set forth in Section  5.5 of the URS  Disclosure
Letter,  as of the  respective  dates such URS SEC Reports were filed or, if any
such URS SEC Reports were amended, as of the date such amendment was filed, each
of the URS SEC Reports (i) complied in all material respects with all applicable
requirements  of the  Securities  Act and the  Exchange  Act,  and the rules and
regulations  promulgated  thereunder,  and  (ii)  did  not  contain  any  untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary in order to make the statements therein, in light of
the  circumstances  under  which they were  made,  not  misleading.  Each of the
audited  consolidated  financial  statements and unaudited  consolidated interim
financial statements of URS (including any related notes and schedules) included
(or  incorporated  by reference) in its Annual  Reports on Form 10-K for each of
the five fiscal years ended October 31, 1992,  1993,  1994,  1995 and 1996, when
filed,  and Quarterly  Reports on Form 10-Q for all interim  periods  subsequent
thereto (the "URS Financial Statements") fairly present, in conformity with GAAP
applied on a consistent basis (except as may be indicated in the notes thereto),
the  consolidated  financial  position of URS and the URS Subsidiaries as of its
date and the  consolidated  results of operations  and cash flows for the period
then ended (subject to normal year-end  adjustments in the case of any unaudited
interim  financial  statements).  There has been no  change in URS's  accounting
policies or methods of making accounting  estimates or changes in estimates that
are material to the URS Financial  Statements,  except as described in the notes
thereto.

have  conducted  their  business in the ordinary  course,  consistent  with past
practices, and there has not been: (a) any event or occurrence that has resulted
in a  URS  Material  Adverse  Effect,  or  any  development  or  combination  of
developments  of which URS has  knowledge  that is reasonably  likely,  in URS's
commercially  reasonable  judgment,  to result in a URS Material Adverse Effect,
(b) any  declaration,  setting aside or payment of any dividend or other capital
distributions  in  respect  of any of its  capital  stock or any  redemption  or
repurchase  or other  acquisition  of any shares of its capital  stock,  (c) any
increase in the regular  compensation of any of the officers or employees of URS

ordinary  course of business in accordance with its customary  practices  (which
shall  include  normal  periodic  performance  reviews,  promotions  and related
compensation increases),  (d) any incurrence,  assumption or guarantee by URS or
any of the URS Subsidiaries of any indebtedness for borrowed money other than in
the  ordinary  course  of  business  consistent  with  past  practices,  (e) any
transaction  or commitment  made, or any contract or agreement  entered into, by
URS or any of the URS Subsidiaries  (including the acquisition or disposition of
any assets) or any  relinquishment  by URS or any of the URS Subsidiaries of any
contract or other right,  in either case,  material to URS's business taken as a
whole,  other  than  transactions  and  commitments  in the  ordinary  course of
business   consistent  with  past  practices  and  those  contemplated  by  this
Agreement,  (f) any change in any method of accounting or accounting practice by
URS or any of the URS  Subsidiaries,  except for any such change  after the date
hereof required by reason of a mandatory concurrent change in GAAP, (g) any loss
or damage to the properties or assets of URS or the URS  Subsidiaries  which has
resulted or is reasonably  likely to result in a URS Material Adverse Effect, or

tribunal,   commission,   board,  agency  or  instrumentality,   or  before  any
arbitrator)  pending or, to the best  knowledge  of URS,  threatened  against or
affecting  URS or any of the URS  Subsidiaries,  the  outcome  of which,  in the
reasonable judgment of URS, is likely individually or in the aggregate to have a
URS Material Adverse Effect,  or which challenges the validity of this Agreement
or  seeks  to  prevent,  enjoin,   materially  alter  or  materially  delay  the
transactions contemplated hereby, nor is there any judgment, decree, injunction,
rule  or  order  of any  court,  governmental  department,  commission,  agency,
instrumentality or arbitrator outstanding against URS or

                                       34.

foreseen, in the future may have, any such effect.

         Section 5.8 Absence of Undisclosed Liabilities.  Except for liabilities
or  obligations  which are  accrued or  reserved  against  in the URS  Financial
Statements  (or  reflected in the notes  thereto) or which were  incurred  after
December 31, 1996 in the ordinary  course of business and  consistent  with past
practices or in connection with the transactions contemplated by this Agreement,
URS and the URS Subsidiaries do not have any liabilities or obligations (whether
absolute,  accrued,  contingent or otherwise) of a nature required by GAAP to be
reflected in a consolidated balance sheet (or reflected in the notes thereto).

occurred  which  with  notice or the lapse of time or both  would  constitute  a
violation  or breach of, or default  under) any term,  condition or provision of
(a) its Certificate or Articles of Incorporation, as the case may be, or Bylaws,
(b) any note,  bond,  mortgage,  deed of trust,  security  interest,  indenture,
license,  contract,  agreement,  plan, lease,  commitment or other instrument or
obligation  to which URS or any of the URS  Subsidiaries  is a party or by which
any of them or any of their  properties or assets may be bound or affected,  (c)
any order, writ, injunction,  decree,  statute, rule or regulation applicable to
URS or any of the URS Subsidiaries or any of their properties or assets,  or (d)
any certificate of need, accreditation,  registration, license, permit and other
consent or approval of  governmental  agencies  or  accreditation  organization,
except in the case of clauses (b), (c) and (d) above for violations, breaches or

shall hold a meeting of its  stockholders  at the earliest  practicable  date to
submit this Agreement and related matters for their  consideration and approval,
which  approval  shall be  recommended  by  Woodward-Clyde's  Board of Directors
(subject  to  the  fiduciary   obligations   of  its  directors  and  officers).
Woodward-Clyde  shall send to its  stockholders,  for the purpose of considering
and voting upon the Merger,  a Proxy  Statement  satisfying all  requirements of
applicable state and Federal laws, shall use its best efforts to obtain approval
of this Agreement and the Merger by the requisite  stockholder  vote (subject to

<PAGE>

employees, agents and representatives not to, directly or indirectly, encourage,
solicit,  accept,  initiate or conduct discussions or negotiations with, provide
any  information  to,  or  enter  into  any  agreement  with,  any  corporation,
partnership,  limited  liability  company,  person  or  other  entity  or  group
concerning the acquisition of all or a substantial part of the assets,  business
or  capital  stock  of   Woodward-Clyde,   whether  through  purchase,   merger,
consolidation,   exchange  or  any  other  business  combination  (each  of  the
foregoing, an "Acquisition Proposal").  Notwithstanding anything to the contrary
in the preceding sentence,  nothing herein shall prevent  Woodward-Clyde and its
officers and directors, from considering, discussing, negotiating, responding to
and  accepting  unsolicited  firm offers for any such  transaction  from persons
other  than  URS  if  and  to  the  extent  that,  in  the  written  opinion  of
Woodward-Clyde's outside counsel, failure to do so would be reasonably likely to
constitute a violation of applicable law or a breach of the fiduciary  duties of
Woodward-Clyde's  directors  to  Woodward-Clyde's  stockholders.  Woodward-Clyde
shall  immediately  provide written notice to URS of the terms and other details
of any such unsolicited inquiry or proposal relating to an Acquisition Proposal.
In the event that Woodward-Clyde or any of its officers or directors enters into
any discussions for any reason or negotiations  relating to any such Acquisition
Proposal  from any  person  other  than URS,  Woodward-Clyde  shall  immediately
reimburse URS for all expenses and costs incurred by URS in connection  with the
transactions  contemplated  by this  Agreement  up to an  aggregate  maximum  of
$500,000,  whether  or not  Woodward-Clyde  ultimately  responds  favorably  to,
accepts or enters into any letter of intent,  understanding  or other  agreement
relating  to  such  Acquisition   Proposal.  In  addition,  in  the  event  that
Woodward-Clyde  or any of its officers or directors  shall enter into any letter
of intent, understanding or other agreement with a party other than URS relating
to the  acquisition  of all or a  substantial  part of the  assets,  business or
capital   stock   of   Woodward-Clyde,   whether   through   purchase,   merger,
consolidation,  exchange or any other business combination,  either in violation
of the  no-shop  agreement  set forth in this  Section or within nine (9) months
after  termination  of this  Agreement  for any reason,  then  immediately  upon
entering  into  such  letter  of  intent,   understanding  or  other  agreement,
Woodward-Clyde shall pay to URS a termination fee in the amount of $3.5 million,
less the aggregate amount of the URS expenses and costs previously reimbursed to
URS  pursuant to the  preceding  sentence  (the  "Termination  Fee");  provided,
however,  that such  Termination Fee shall not be payable if, prior to the entry
by Woodward-Clyde into such letter of intent,  understanding or other agreement,
URS has unilaterally declined to close the Merger, or the parties have agreed to
terminate this  Agreement by mutual written  consent under Section 9.1.1 of this
Agreement,  or this  Agreement  has been properly  terminated by  Woodward-Clyde
(without  any  breach of its  obligations  under  this  Agreement)  pursuant  to
Sections  9.1.2(ii),  9.1.5 or 9.1.6. The parties acknowledge and agree that the
expense  reimbursement  obligation and Termination Fee described in this Section
shall be the exclusive remedy to URS in the event of a breach by  Woodward-Clyde
of this Section 6.2.3, and, in any such event, URS shall be

                                       42.

<PAGE>

entitled,  in  addition to  receiving  such  payments,  to  equitable  remedies,
including, without limitation, specific performance and enjoining of any actions
determined  to be in  breach of this  Agreement;  provided  that such  exclusive
remedy  limitation  applicable to breach of this Section 6.2.3 shall not prevent
URS from  pursuing  any and all  remedies  available  to it,  including  without
limitation seeking actual and consequential damages and equitable remedies,  for
breach by Woodward-Clyde of any other provision of this Agreement.

                  6.2.4  Maintenance  of Business.  Woodward-Clyde  will use its
best efforts to carry on and preserve  its business and its  relationships  with
clients,  customers,  suppliers,  employees and others in substantially the same
manner  as it has  prior to the date  hereof.  If the  executive  management  of
Woodward-Clyde  becomes aware of a material  deterioration  in the  relationship
with  any  significant  client,  customer,  supplier  or key  employee,  it will
promptly  bring such  information  to the  attention  of URS in writing  and, if
requested by URS, will use its best efforts to restore the relationship.

                  6.2.5 Access.  Woodward-Clyde shall afford to URS and to URS's
financial  advisors,  legal counsel,  accountants,  financing  sources and other
authorized  representatives  access during normal  business  hours to all of its
books, records, properties, offices and personnel.

                  6.2.6  Liability  Insurance.  On or before the  Closing  Date,
Woodward-Clyde  shall  procure  (subject  to the  approval  of  URS)  continuing
directors' and officers'  liability  coverage (tail  coverage) for directors and
officers  of  Woodward-Clyde  who have  served  as  directors  and  officers  of
Woodward-Clyde or its affiliates (the  "Woodward-Clyde D & O Policy"),  prior to
the Effective Time of the Merger,  with respect to acts or failures to act prior
to the Effective  Time of the Merger.  Said policy shall have a term of not less
than three (3) years after the Closing Date.

                  6.2.7 Affiliate Agreements.  Woodward-Clyde shall use its best
efforts to deliver to URS, prior to the date the preliminary  Proxy Statement is
mailed to the SEC, an agreement or agreements,  in form and substance reasonably
satisfactory to URS, signed by each officer, director, holder of more than 1% of
the outstanding  Woodward-Clyde  Common Stock or Woodward-Clyde  Preferred Stock
and each other person who may be deemed to be an "affiliate"  of  Woodward-Clyde
as  defined  in  the  Securities  Act,  providing  a  "continuity  of  interest"
representation  in a manner  sufficient to satisfy the  requirements of the Code
regarding the tax-free nature of the Merger and  acknowledging  the restrictions
on  transfer  of the URS Common  Stock to be  received  by them  pursuant to the
Merger under Rules 144 and 145 promulgated under the Securities Act.

                                       43.

                  6.2.8 Comfort  Letter.  Woodward-Clyde  shall deliver to URS a
comfort letter, dated a date not more than two (2) business days before the date
upon  which the Form S-4  becomes  effective,  from  Ernst & Young,  independent
public  accountants  for  Woodward-Clyde,   in  form  and  substance  reasonable
satisfactory to URS,  covering such matters as are normally covered in a comfort
letter  delivered  in  connection  with a  registration  statement  on Form  S-4
covering transactions similar to the Merger.

                  6.2.9 FIRPTA  Matters.  At the Closing,  Woodward-Clyde  shall
deliver (a) to URS a statement (in form reasonable acceptable to URS) conforming
to the  requirements of Section  1.897-2(h)(1)(i)  of the United States Treasury
Regulations,  and (b) to the Internal Revenue Service the notification  required
under Section 1.897-2(h)(2) of such Regulations.

                  6.2.10    Employment    and     Noncompetition     Agreements.
Woodward-Clyde  shall use its best efforts to cause such of its key employees as
may be  identified  in advance  by URS to execute  and  deliver  Employment  and
Noncompetition  Agreements  in such  form  and  substance  as may be  reasonably
requested by URS.

         Section 6.3  Covenants of URS.  During the period from the date of this
Agreement  until  the  earlier  of the  termination  of  this  Agreement  or the
Effective Time of the Merger,  URS and the Subsidiary agree (except as expressly
contemplated   by  this   Agreement  or  with  the  prior  written   consent  of
Woodward-Clyde) that:

                  6.3.1 Stockholders' Meeting; Proxy Statement. URS shall hold a
meeting  of its  stockholders  at the  earliest  practicable  date to submit the
Agreement  and  related  matters for their  consideration  and  approval,  which
approval  shall be  recommended  by URS's  Board of  Directors  (subject  to the
fiduciary  obligations  of its  directors  and  officers).  URS  shall  send its
stockholders,  for purposes of considering  and voting upon the Merger,  a Proxy
Statement  satisfying all the requirements of applicable state and Federal laws,

and the Pacific  Exchange a listing  application  covering the shares of the URS
Common Stock to be issued in connection with the Merger.  URS shall use its best
efforts to obtain,  prior to the Effective Time of the Merger,  approval for the

ordinary course in substantially the same manner as heretofore conducted and, to

with clients,  customers,  suppliers  and  employees.  URS will promptly  notify
Woodward-Clyde  of any event or  occurrence  or  emergency  not in the  ordinary
course of business which could result in a URS Material  Adverse Effect.  In the
event  URS  is  considering  any  material  transaction  or  series  of  related
transactions  involving the acquisition or disposition of assets with a value or
for  consideration  in excess of $20  million,  it will first  consult  with the
executive management of Woodward-Clyde  regarding such transaction(s),  provided
that  the  approval  of  Woodward-Clyde  shall  not be  required  for  any  such
transaction(s)  (except as indicated  in the  following  sentence).  Without the
prior  approval  of  Woodward-Clyde,  prior to the Closing  Date,  URS shall not

                            (iv)  This  Agreement  has  been  duly  and  validly
authorized,  executed and delivered by URS and the Subsidiary and,  assuming due

                              ADDITIONAL AGREEMENTS

         Section   8.1   Public   Announcements.   URS,   the   Subsidiary   and
Woodward-Clyde  agree that they will not issue any press  release  or  otherwise
make any public  statement or respond to any press  inquiry with respect to this
Agreement or the transactions  contemplated hereby without the prior approval of
the other party (which  approval will not be unreasonably  withheld),  except as
may be required by applicable law.

         Section 8.2  Confidentiality.  No party to this Agreement  shall use or
disclose any non-public  information obtained from another party for any purpose
unrelated to the Merger,  and, if this  Agreement is  terminated  for any reason
whatsoever, each party shall return to the other all originals and copies of all
documents and papers containing all information furnished to such party pursuant
to this Agreement, or during the negotiations which preceded this Agreement, and
shall  neither use nor disclose any such  information  except to the extent that
such information is available to the public,  is rightfully  obtained from third
parties, or is independently developed.

         Section  8.3  Additional  Agreements.  In case at any  time  after  the
Effective  Time of the Merger any  further  action is  reasonably  necessary  or
desirable to vest the Surviving  Corporation  with full title to all properties,
assets,  rights,   approvals,   immunities  and  franchises  of  either  of  the
constituent corporations,  the proper officers and directors of each corporation
which is a party to this  Agreement  shall  take  all such  necessary  corporate
action.

         Section 8.4 Non-Liability of Agents and  Stockholders.  No stockholder,
director,  officer or employee of any party hereto shall be individually  liable
for any breach of the  representations,  warranties  or  covenants  of any party

part of such stockholder, director, officer or employee.

         Section 8.5 Woodward-Clyde Capital Accumulation  (Retirement) Plan; GCH
Acquisition Corp.  Retirement Program.  Woodward-Clyde will take and cause to be
taken any and all actions  necessary or appropriate,  including any necessary or
appropriate plan amendments,  (i) to suspend any obligation to contribute shares
of Woodward-Clyde  Stock to, or to redeem shares of  Woodward-Clyde  Stock from,
the  Woodward-Clyde  Capital  Accumulation  (Retirement)  Plan (the  "Retirement
Plan") during the period from the date of this  Agreement to the Effective  Time
of the Merger,  (ii) to either,  at the option of URS,  terminate the Retirement
Plan and/or the GCH Acquisition Corp. Retirement Program (the

                                       51.

<PAGE>

"GCH Plan") one day prior to the  Effective  Time of the Merger and/or merge the
Retirement  Plan and the CGH Plan with and into the URS 401(k)  Retirement  Plan
from the  Effective  Time of the  Merger,  and (iii) to  eliminate  any  options
available to the Retirement Plan, the CGH Plan or their participants to purchase

         Section 8.6  Woodward-Clyde  Annual Bonus Plan.  Following the Closing,
URS will cause to be completed an audit of the consolidated financial statements
of Woodward-Clyde  for the period beginning on January 1, 1997 and ending on the
Closing Date (the "Bonus  Period"),  which will be prepared in  accordance  with
GAAP applied on a consistent basis with the Woodward-Clyde  Financial Statements
(the  "Woodward-Clyde  Interim Financial  Statements").  Promptly  following the
completion  of such  audit,  URS will  cause the  Surviving  Corporation  to pay
bonuses to the former employees of  Woodward-Clyde  in a manner  consistent with
prior practices, but prorated for the Bonus Period, as follows:

                  8.6.1 Bonus Pool. The aggregate  amount of the bonus pool (the
"Bonus Pool") shall equal the "Annualization Ratio" multiplied by the greater of
either (i) $500,000 or (ii) 50% of the excess, if any, of Annualized 1997 Profit
over $8,000,000.  "Annualized 1997 Profit" shall mean the product of (A) the net
income of Woodward-Clyde for the Bonus Period, as reported in the Woodward-Clyde
Interim  Financial  Statements,  as adjusted (i) before any  deduction for taxes
(ii) before any  deduction  for any bonuses to be paid  pursuant to this Section
8.6, (iii) before the addition of any net income  attributable  to settlement of
the GeoCon  Litigation,  (iv) before the  deduction of any  litigation  expenses
attributable  to the GeoCon  Litigation  up to the amount of the proceeds of any
settlement of the GeoCon  Litigation,  and (v) before  deduction of the fees and
expenses of OC and legal expenses,  loan pre-payment  charges and other external
expenses   incurred  by  Woodward-Clyde  in  connection  with  the  negotiation,
execution and delivery of this Agreement and  consummation  of the  transactions
contemplated  hereby,  divided by (B) the  Annualization  Ratio.  "Annualization
Ratio" means the ratio  determined  by dividing the number of actual days in the
Bonus Period by 365.

                  8.6.2 Bonus Pool  Allocation.  On or before the Closing  Date,
Woodward-Clyde  shall  appoint  a  committee  of  Woodward-Clyde  officers  (the
"Allocation  Committee")  which  will have  responsibility  for  allocating  the
amounts  available in the Bonus Pool.  The Allocation  Committee  shall allocate
bonuses  among those  individuals  who were  employed by  Woodward-Clyde  on the
Closing Date based upon its  evaluation  of the relative  contributions  of such
employees to Woodward-Clyde during the ten month period ending October 31, 1997,
and in a manner consistent with the past annual bonus plan allocation  practices
of  Woodward-Clyde.  The final bonus  allocations  determined by the  Allocation
Committee shall

                                       52.

<PAGE>

be subject to the final  approval of the Chief  Executive  Officer of URS, which
shall not be unreasonably withheld.

         Section 8.7 URS Board of Directors.  On or before the Closing Date, URS
will cause the authorized  number of directors serving on its Board of Directors
to be increased by two (2), and will cause  Messrs.  Frank S. Waller  ("Waller")
and  Jean-Yves  Perez  ("Perez"),  or in the  event  either of them is unable to
serve, Mr. Robert K. Wilson ("Wilson"), to be appointed to the vacancies created
effective  as of the  Effective  Time of the Merger.  Subsequent  to the Closing
Date,  URS will take such  actions as may be  reasonably  necessary  to nominate
Waller  and Perez  (or,  in the event  that  either or both of them is unable to
serve or has ceased to be an employee of URS or any of its Subsidiaries, Wilson)
for reelection,  and to vote any proxies  obtained on behalf of the URS Board of
Directors for their reelection,  at any meeting of the URS stockholders at which
directors  are to be  elected  or in  connection  with any action to be taken by
written consent by the URS stockholders for the election of directors, until the
second anniversary of the Closing Date. In the event that either Waller or Perez
(or Wilson if he is then  serving as a director of URS) ceases to be employed by
URS or any of its Subsidiaries within such two year period, then he shall resign
his position as a director concurrent with such termination of employment.

         Section 9.1  Termination.  This Agreement may be terminated at any time
prior  to the  Effective  Time  of the  Merger,  whether  before  or  after  the
Stockholder Approvals have been obtained:

                  9.1.1     by mutual written consent of URS and Woodward-Clyde;

                  9.1.2 by either  Woodward-Clyde  or URS if (i) the Stockholder
Approvals  shall  not  have  been  obtained  at  duly  called  meetings  of  the
stockholders  of  Woodward-Clyde  and  URS or any  adjournment  thereof;  (ii) a
Governmental Entity of competent jurisdiction shall have issued an order, decree
or ruling  or taken  any other  action  permanently  restraining,  enjoining  or
otherwise  prohibiting the transactions  contemplated by this Agreement and such
order, decree, ruling or other action shall have become final and nonappealable;
or (iii) the Merger  shall not have been  consummated  before  December 31, 1997
(provided  that the  terminating  party is not then in  material  breach  of any
representation, warranty, covenant or agreement contained in this Agreement);

                  9.1.3 By URS if there has been a breach by  Woodward-Clyde  of
any  representation,  warranty,  covenant or other  agreement in this  Agreement
which has a Woodward-Clyde Material Adverse Effect, and such breach has not been

breach,  within thirty (30) days after written notice of such breach is given by
URS to Woodward-Clyde;

                  9.1.4  By  URS  if   Woodward-Clyde   shall   enter  into  any
discussions,  negotiations  or any  letter  of  intent,  understanding  or other
agreement relating to an Acquisition Proposal, provided that no such termination
shall affect the rights of URS to  reimbursement of expenses and the Termination
Fee as provided in Section 6.2.3; or

                  9.1.5 By  Woodward-Clyde  if there has been a breach by URS or
the  Subsidiary  of any  material  representation,  warranty,  covenant or other
agreement,  and such breach has not been cured,  or URS and the Subsidiary  have
not commenced  reasonable  efforts to cure such breach,  within thirty (30) days
after written  notice of such breach is given by  Woodward-Clyde  to URS. In the
event of a breach  by URS of the  covenant  set  forth in the last  sentence  of
Section 6.3.4, then termination of this Agreement under this Section 9.1.5 shall
be the sole remedy of Woodward-Clyde with respect to such breach.

                                       54.

<PAGE>

                  9.1.6 By  Woodward-Clyde if any of the conditions set forth in
Section  7.1  hereof  shall  not  have  been  fulfilled  on or prior to the date

provisions of Section 6.2.3, this Section 9.2, and the Confidentiality Agreement
shall  survive  any such  termination,  and (ii) no party  whose  breach  of its
representations, warranties, covenants or agreements set forth in this Agreement
was the  basis of the  other  party's  termination  of this  Agreement  shall be
relieved  from  liability for damages  occasioned by such breach,  including any
expenses  incurred by the other party in connection  with this Agreement and the
transactions contemplated hereby.

contained  herein.  Any  agreement  on the  part of a party  hereto  to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.  The failure of any party to this  Agreement  to
assert any of its rights under this  Agreement  shall not constitute a waiver of
these rights.

CONFIDENTIAL

August 18, 1997

Board of Directors
URS Corporation
100 California Street, Suite 500
San Francisco, California  94111

Members of the Board:

You have  requested  our opinion as to the fairness,  from a financial  point of
view, to URS Corporation ("URS") of the consideration to be paid by URS pursuant
to the terms and subject to the  conditions  set forth in the Agreement and Plan
of Merger,  dated as of August 18, 1997 (the "Merger  Agreement"),  by and among
Woodward-Clyde Group, Inc. ("Woodward-Clyde"),  URS and W-C Acquisition Corp., a
wholly owned  subsidiary of URS  ("Subsidiary").  As more fully described in the
Merger  Agreement,  (i)  Woodward-Clyde  will be merged with and into Subsidiary
(the "Merger") and (ii) the outstanding shares of the preferred stock, par value
$0.01 per share, of Woodward-Clyde (the  "Woodward-Clyde  Preferred Stock") will
be converted  into the right to receive  $8,306,130 in the aggregate in cash and
each  outstanding  share of the common  stock,  par value  $0.01 per  share,  of
Woodward-Clyde  (the  "Woodward-Clyde  Common Stock") will be converted into the
right to receive (A) that number of shares of the common stock,  par value $0.01
per share,  of URS (the "URS  Common  Stock")  equal to the result  obtained  by
dividing (x) $65.0 million  divided by the average last closing price of the URS
Common Stock on the New York Stock Exchange over the last 20 trading days ending
two  trading  days prior to the  closing  date of the Merger  (the "URS  Average
Closing Price"),  but in no event less than $12.50 or greater than $16.07 by (y)
the  aggregate  number of  shares of  Woodward-Clyde  Common  Stock  outstanding
immediately  prior to the effective time of the Merger (the  "Applicable  Common
Multiple") and (B) a cash amount  determined by dividing (x) $26,693,870 plus an
amount  equal to the excess,  if any, of $65.0  million  over the product of the
Applicable  Common  Multiple,  the aggregate number of shares of Woodward Common
Stock outstanding  immediately prior to the effective time of the Merger and the
URS  Average   Closing  Price  by  (y)  the   aggregate   number  of  shares  of
Woodward-Clyde Common Stock outstanding  immediately prior to the effective time
of the Merger (the  "Applicable  Common Cash Component"  and,  together with the
Applicable Common Multiple, the "Merger Consideration").

In  arriving  at  our  opinion,  we  reviewed  the  Merger  Agreement  and  held
discussions  with certain senior officers,  directors and other  representatives
and advisors of URS and certain senior  officers and other  representatives  and
advisors of Woodward-Clyde  concerning the businesses,  operations and prospects
of URS and  Woodward-Clyde.  We examined certain publicly available business and
financial  information  relating  to URS  and  certain  business  and  financial
information  relating to Woodward-Clyde  as well as certain financial  forecasts
and other information and data for URS and Woodward-Clyde which were provided to
or  otherwise  discussed  with  us by the  respective  managements  of  URS  and
Woodward-Clyde, including information relating to certain strategic implications
and operational  benefits anticipated to result from the Merger. We reviewed the
financial  terms of the Merger as set Forth in the Merger  Agreement in relation
to, among other things: current and historical market prices and trading volumes
of URS Common Stock;  the historical and projected  earnings and other operating
data of URS and Woodward- Clyde; and the capitalization and financial  condition
of URS and Woodward-Clyde.  We considered, to the extent publicly available, the
financial terms of certain other similar transactions recently effected which we
considered  relevant in evaluating  the Merger and analyzed  certain  financial,
stock market and other publicly available information relating to the businesses
of other companies whose operation we considered relevant in evaluating those of
URS and  Woodward-Clyde.  We also  evaluated the  potential pro forma  financial
impact of the Merger on URS. In addition to the  foregoing,  we  conducted  such
other analyses and examinations  and considered such other  financial,  economic
and market criteria as we deemed appropriate in arriving at our opinion.

In  rendering  our  opinion,  we have  assumed and relied,  without  independent
verification,  upon the accuracy and  completeness  of all  financial  and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial  forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the  managements  of URS and  Woodward-Clyde  that such forecasts and
other information and data were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the respective  management of URS
and   Woodward-Clyde  as  to  the  future  financial   performance  of  URS  and
Woodward-Clyde   and  the  strategic   implications  and  operational   benefits
anticipated to result from the Merger. We have assumed,  with your consent, that
the Merger will be treated as a tax-free  reorganization  for federal income tax
purposes.  We are not  expressing  any  opinion  as to what the value of the URS
Common  Stock  actually  will  be when  issued  to  Woodward-Clyde  stockholders
pursuant  to the  Merger or the price at which the URS  Common  Stock will trade
subsequent to the Merger.  We have not made or been provided with an independent
evaluation or appraisal of the assets or  liabilities  (contingent or otherwise)
of URS or  WoodWard-Clyde  nor  have  we made  any  physical  inspection  of the
properties  or  assets  of URS or  Woodward-Clyde.  We  were  not  requested  to
consider, and our opinion does not address, the relative merits of the Merger as
compared to any

alternative  business  strategies  that might exist for URS or the effect of any
other  transaction in which URS might engage.  Our opinion is necessarily  based
upon  information  available  to us,  and  financial,  stock  market  and  other
conditions  and  circumstances  existing  and  disclosed  to us,  as of the date
hereof.

Smith Barney has been engaged to render  financial  advisory  services to URS in
connection  with  the  Merger  and  will  receive  a fee for  such  services,  a
significant  portion of which is contingent upon the consummation of the Merger.
We also will receive a fee upon delivery of this opinion. In the ordinary course
of our business, we and our affiliates may actively trade or hold the securities
of URS for our own account or for the account of our customers and, accordingly,
may at any time hold a long or short position in such  securities.  In addition,
we and our affiliates  (including  Travelers  Group Inc. and its affiliates) may
maintain relationship with URS and Woodward-Clyde.

Our  advisory  services  and the opinion  expressed  herein are provided for the
information  of the Board of Directors of URS in its  evaluation of the proposed
Merger,  and  our  opinion  is  not  intended  to  and  does  not  constitute  a
recommendation to any stockholder as to how such stockholder  should vote on any
matter  relating to the  proposed  Merger.  Our opinion may not be  published or
otherwise used or referred to, nor shall any public reference to Smith Barney be
made, without our prior written consent.

Based upon and subject to the foregoing,  our experience as investment  bankers,
our work as described above and other factors we deemed relevant,  we are of the
opinion that, as of the date hereof,  the Merger  Consideration  is fair, from a
financial point of view, to URS.

Very truly yours,

The Board of Directors
Woodward-Clyde Group, Inc.
Stanford Place 3, Suite 600

Denver, CO 80237

Dear Sirs:

You have  requested  our opinion as to the fairness,  from a financial  point of
view,  to the current  holders of common  stock of  Woodward-Clyde  Group,  Inc.
("Woodward-Clyde"), of the consideration to be received by such holders pursuant
to the final  Agreement  and Plan of Merger  prepared as of August 18, 1997 (the
"Merger Agreement"),  by and among  Woodward-Clyde  Group, Inc., URS Corporation
("URS") and W-C  Acquisition  Corporation  ("Mergersub").  The Merger  Agreement
provides that, among other things,  (i)  Woodward-Clyde  will be merged with and
into Mergersub,  and the separate  existence of  Woodward-Clyde  shall thereupon
cease,  and Mergersub  shall  continue its corporate  existence as the surviving
corporation  under  the  name of  Woodward-Clyde  Group,  Inc.  (the  "Surviving
Corporation"),  and (ii) the  consideration  paid is as  defined  in the  Merger
Agreement.

In arriving at our opinion,  we have (i) reviewed the latest  available draft of
the Merger Agreement,  (ii) reviewed the historical financial statements and the
financial  projections  and other  information  prepared by  representatives  of
Woodward-Clyde  and URS,  (iii)  reviewed  publicly  available  information  for
Woodward-Clyde  and URS,  including,  with  respect to URS,  periodic  and other
reports filed with the  Securities  and Exchange  Commission,  (iv) reviewed the
reported  market  prices and trading  volumes for URS'  common  stock,  (v) held
discussions  with   representatives   of   Woodward-Clyde   and  URS  concerning
Woodward-Clyde's and URS' historical and current operations, financial condition
and prospects,  and (vi) reviewed such other  documents and financial,  economic
and market criteria and made such other  investigations as we deemed appropriate
for the purposes of such opinion.

We also considered  certain stock market data of URS and compared that data, and
historical operating data of URS and Woodward-Clyde, with similar data for other
publicly held  companies in businesses  similar to those of  Woodward-Clyde  and
URS. We  considered to the extent  publicly  available,  the financial  terms of
certain  other  business  combinations  which have recently  been  effected.  In
addition, we conducted an extensive process of contacting numerous third parties
to  solicit   indications   of  interest  in  acquiring   all  or  any  part  of
Woodward-Clyde.

In  connection  with  our  review,  we  have  not  assumed   responsibility  for
independent  verification  of any of the foregoing  information  and have relied
upon its being  complete  and  accurate  in all  respects.  With  respect to the
financial forecasts and other data concerning Woodward-Clyde and URS reviewed by
us, the managements of Woodward-Clyde and URS advised us that such forecasts and
other  data  have  been  reasonably  prepared  on bases  reflecting  their  best
currently  available  estimates  and  judgments  as to  their  future  financial
performance.  In  addition,  we have  not  made  an  independent  evaluation  or
appraisal  of  the  assets  or   liabilities   (contingent   or   otherwise)  of
Woodward-Clyde  or URS, nor have we been furnished with any such  evaluations or
appraisals. We have assumed, without independent  verification,  the accuracy of
the advice and  conclusions of the parties' legal counsel and  accountants  with
respect  to  accounting   and  tax  matters  as  provided  to   Oppenheimer   by
Woodward-Clyde's management,  including without limitation, the treatment of the
Merger as a tax-free  reorganization  for federal  income tax  purposes  and the
accounting  treatment  of the merger as a purchase.  We express no opinion as to
what the value of the URS common stock  actually  will be when issued to holders
of Woodward-Clyde  common stock pursuant to the Merger or the price at which URS
common stock will trade  subsequent  to the Merger.  Our opinion is  necessarily
based on information  available to us and general economic,  financial and stock
market  conditions and circumstances as they exist and can be evaluated by us on
the date hereof.

As  part  of our  investment  banking  business,  we are  regularly  engaged  in
valuations of businesses  and  securities in connection  with  acquisitions  and
mergers,   underwritings,   secondary   distributions  of  securities,   private
placements and valuations for other purposes.

We acted as financial  advisor to the Board of Directors  of  Woodward-Clyde  in
rendering this opinion and will receive a fee for our services. We also acted as
financial advisor to Woodward-Clyde in the Merger for which we expect to receive
a fee for our services.  In the ordinary  course of its business,  Oppenheimer &
Co., Inc. and its affiliates may actively trade  securities of URS for their own
accounts  and for the accounts of customers  and,  accordingly,  may at any time
hold a long or short position in such securities.

On  August  14,  1997,  we made a  presentation  to the  Board of  Directors  of
Woodward-Clyde  stating  that,  based on the  terms of the  consideration  to be
received by the current holders of Woodward-Clyde  common stock as stated in the
draft  Agreement and Plan of Merger dated as of August 13, 1997,  and additional
assumptions  made regarding  terms undefined in such draft Agreement and Plan of
Merger,  such  consideration is fair to such holders,  from a financial point of
view.  The  terms of the  consideration  to be paid to the  current  holders  of
Woodward-Clyde common stock as stated in the Merger Agreement are not materially
different from the terms stated in the draft  Agreement and Plan of Merger dated
as of August 13, 1997 or from the  assumptions we made regarding terms undefined
in such draft Agreement and Plan of Merger.  This fairness  opinion confirms our
oral  opinion  given on August 14,  1997,  that  based  upon and  subject to the
foregoing and such other factors as we deem relevant, it is our opinion that, as
of August  14,  the  consideration  to be  received  by the  current  holders of
Woodward-Clyde  common  stock  pursuant to the Merger  Agreement is fair to such
holders,  from a financial point of view.  This fairness  opinion is directed to
the Board of Directors of  Woodward-Clyde in its consideration of the Merger and
is not a recommendation to any holder of  Woodward-Clyde  common stock as to how
such holder  should vote with  respect to such  Merger.  Neither  this  fairness
opinion nor the services provided by Oppenheimer in connection  therewith may be
publicly disclosed or referred to in any manner by Woodward-Clyde or URS without
Oppenheimer's prior written approval. This fairness opinion may be reproduced in
full in any proxy or  information  statement  mailed to the  current  holders of
Woodward-Clyde  common stock and in any  registration  statement  related to the
Merger  filed  by  Woodward-Clyde  or  URS  with  the  Securities  and  Exchange
Commission  pursuant to the Securities Act of 1933, and Oppenheimer  consents to
the inclusion of this fairness opinion in any such registration statement.  This
fairness  opinion may not otherwise be disclosed  publicly in any manner without
our prior written approval and must be treated as confidential.

Very truly yours,

                                (Delaware Dissenters' Rights)
                    (Section 262 of the Delaware General Corporation Law)


262 APPRAISAL  RIGHTS.--(a)  Any  stockholder of a corporation of this State who
holds  shares  of stock  on the  date of the  making  of a  demand  pursuant  to
subsection  (d) of this section with  respect to such shares,  who  continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise  complied with  subsection (d) of this section and who has neither
voted in favor of the merger or consolidation  nor consented  thereto in writing
pursuant to ss.228 of this title shall be entitled to an  appraisal by the Court
of  Chancery  of the fair value of the  stockholder's  shares of stock under the
circumstances  described in subsections (b) and (c) of this section.  As used in
this  section,  the word  "stockholder"  means a holder  of record of stock in a
stock  corporation  and also a member of record of a nonstock  corporation:  the
words  "stock" and "share"  mean and include what is  ordinarily  meant by those
words and also  membership  or  membership  interest  of a member of a  nonstock
corporation;  and  the  words  "depository  receipt"  mean a  receipt  or  other
instrument  issued  by a  depository  representing  an  interest  in one or more
shares, or fractions thereof,  solely of stock of a corporation,  which stock is
deposited with the depository.

         (b) Appraisal  rights shall be available for the shares of any class or
series of stock of a constituent  corporation in a merger or consolidation to be
effected  pursuant to ss.251 (other than a merger effected pursuant to ss.251(g)
of this title), ss.252, ss.254, ss.257, ss.258, ss.263 or ss.264 of this title:

         (1)  Provided,  however,  that no  appraisal  rights under this section
shall be available for the shares of any class or series of stock,  which stock,
or depository receipts in respect thereof, at the record date fixed to determine
the  stockholders  entitled  to receive  notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or  consolidation,  were either
(i) listed on a national  securities exchange or designated as a national market
system security on an interdealer  quotation system by the National  Association
of Securities  Dealers,  Inc. or (ii) held of record by more than 2,000 holders;
and further  provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require  for  its  approval  the  vote  of the  stockholders  of  the  surviving
corporation as provided in subsection (f) of ss.251 of this title.

         (2) Notwithstanding paragraph (1) of this subsection,  appraisal rights
under this section  shall be available  for the shares of any class or series of
stock of a constituent  corporation  if the holders  thereof are required by the
terms of an agreement of merger or consolidation  pursuant to ss.251,  252, 254,
257, 258, 263 and 264 of this title to accept for such stock anything except:

         a. Shares of stock of the corporation  surviving or resulting from such
merger or consolidation, or depository receipts in respect thereof;

         b. Shares of stock of any other corporation,  or depository receipts in
respect thereof,  which shares of stock or depository  receipts at the effective

securities exchange or designated as a national market system

security on an  interdealer  quotation  system by the  National  Association  of
Securities Dealers, Inc. or held of record by more than 2,000 holders;

         c. Cash in lieu of fractional shares or fractional  depository receipts
described in the foregoing subparagraphs a. and b. of this paragraph; or

         d. Any combination of the shares of stock, depository receipts and cash
in lieu of fractional shares or fractional  depository receipts described in the
foregoing subparagraphs a., b. and c. of this paragraph.

         (3) In the event all of the stock of a subsidiary Delaware  corporation
party to a merger effected under ss.253 of this title is not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be available
for the shares of the subsidiary Delaware corporation.

         (c) Any  corporation  may provide in its  certificate of  incorporation
that  appraisal  rights under this section  shall be available for the shares of
any class or series of its stock as a result of an amendment to its  certificate
of  incorporation,  any merger or  consolidation  in which the  corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

         (d) Appraisal rights shall be perfected as follows:

         (1) If a proposed merger or  consolidation  for which appraisal  rights
are provided  under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with  respect to shares for which  appraisal  rights are  available  pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations,  and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of his
shares shall  deliver to the  corporation,  before the taking of the vote on the
merger or  consolidation,  a written  demand for  appraisal of his shares.  Such
demand  will be  sufficient  if it  reasonably  informs the  corporation  of the
identity of the stockholder  and that the stockholder  intends thereby to demand
the appraisal of his shares. A proxy or vote against the merger or consolidation
shall not constitute such a demand.  A stockholder  electing to take such action
must do so by a separate written demand as herein provided. Within 10 days after
the effective date of such merger or  consolidation,  the surviving or resulting
corporation  shall notify each stockholder of each  constituent  corporation who
has complied with this  subsection and has not voted in favor of or consented to
the merger or  consolidation  of the date that the merger or  consolidation  has
become effective; or

         (2) If the merger or consolidation  was approved  pursuant to ss.228 or
ss.253 of this title, each constituent corporation,  either before the effective
date of the merger or consolidation or within ten days thereafter,  shall notify
each of the  holders  of any  class  or  series  of  stock  of such  constituent
corporation  who are entitled to appraisal  rights of the approval of the merger
or  consolidation  and that appraisal rights are available for any or all shares
of such class or series of stock of a constituent corporation, and shall include
in such notice a copy of this section:  provided that, if the notice is given on
or after the effective date of the merger or consolidation, such notice shall be
given by the surviving or resulting corporation to all such holders of any class
or series of stock of a constituent  corporation  that are entitled to appraisal
rights. Such

                                       2.

<PAGE>



notice  may,  and,  if given on or after  the  effective  date of the  merger or
consolidation, shall, also notify such stockholders of the effective date of the
merger or  consolidation.  Any  stockholder  entitled to  appraisal  rights may,
within 20 days after the date of mailing of such notice,  demand in writing from
the surviving or resulting  corporation  the appraisal of such holder's  shares.
Such demand will be sufficient if it reasonably  informs the  corporation of the
identity of the stockholder  and that the stockholder  intends thereby to demand
the  appraisal  of  such  holder's  shares.   If  such  notice  did  not  notify
stockholders  of the effective date of the merger or  consolidation,  either (i)
each  such  constituent  corporation  shall  send a  second  notice  before  the
effective date of the merger or  consolidation  notifying each of the holders of
any class or series of stock of such  constituent  corporation that are entitled
to appraisal rights of the effective date of the merger or consolidation or (ii)
the  surviving or resulting  corporation  shall send such a second notice to all
such holders on or within 10 days after such effective date; provided,  however,
that if such second  notice is sent more than 20 days  following  the sending of
the first notice,  such second notice need only be sent to each  stockholder who
is entitled to appraisal rights and who has demanded  appraisal of such holder's
shares in  accordance  with this  subsection.  An affidavit of the  secretary or
assistant secretary or of the transfer agent of the corporation that is required
to give either  notice that such notice has been given shall,  in the absence of
fraud,  be prima facie  evidence of the facts  stated  therein.  For purposes of
determining the stockholders entitled to receive either notice, each constituent
corporation  may fix, in  advance,  a record date that shall be not more than 10
days  prior to the date the  notice is given,  provided,  that if the  notice is
given on or after the effective date of the merger or consolidation,  the record
date shall be such effective  date. If no record date is fixed and the notice is
given  prior to the  effective  date,  the  record  date  shall be the  close of
business on the day next preceding the day on which the notice is given.

         (e)  Within  120  days  after  the  effective  date  of the  merger  or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with  subsections  (a) and (d) hereof and who is otherwise  entitled to
appraisal  rights,  may file a petition  in the Court of  Chancery  demanding  a
determination   of  the   value  of  the   stock   of  all  such   stockholders.
Notwithstanding  the  foregoing,  at any time within 60 days after the effective
date of the merger or  consolidation,  any  stockholder  shall have the right to
withdraw  his demand for  appraisal  and to accept  the terms  offered  upon the
merger or consolidation.  Within 120 days after the effective date of the merger
or  consolidation,  any  stockholder  who has complied with the  requirements of
subsections  (a) and (d)  hereof,  upon  written  request,  shall be entitled to
receive  from  the  corporation  surviving  the  merger  or  resulting  from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or  consolidation  and with respect to which  demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written  statement shall be mailed to the stockholder  within 10 days after
his  written  request  for such a statement  is  received  by the  surviving  or
resulting  corporation  or within 10 days  after  expiration  of the  period for
delivery of demands for  appraisal  under  subsection  (d) hereof,  whichever is
later.

         (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof  shall be made upon the surviving or resulting  corporation,  which
shall  within 20 days after such  service  file in the office of the Register in
Chancery in which the petition was filed a duly  verified  list  containing  the
names and  addresses of all  stockholders  who have  demanded  payment for their
shares and with whom  agreements  as to the value of their  shares have not been
reached

                                       3.

by the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation,  the petition shall be accompanied by such a
duly verified list, The Register in Chancery,  if so ordered by the Court, shall
give  notice of the time and place  fixed for the  hearing of such  petition  by
registered or certified  mail to the surviving or resulting  corporation  and to
the stockholders shown on the list at the addresses therein stated.  Such notice
shall also be given by 1 or more  publications at least 1 week before the day of
the  hearing,  in a newspaper  of general  circulation  published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by  publication  shall be approved by the Court,  and
the costs thereof shall be borne by the surviving or resulting corporation.

         (g) At the  hearing on such  petition,  the Court shall  determine  the
stockholders who have complied with this section and who have become entitled to
appraisal  rights.  The Court may require the  stockholders who have demanded an
appraisal for their shares and who hold stock  represented  by  certificates  to
submit  their  certificates  of stock to the  Register in Chancery  for notation
thereon of the pendency of the  appraisal  proceedings;  and if any  stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

         (h) After  determining the stockholders  entitled to an appraisal,  the
Court shall appraise the shares,  determining  their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger or
consolidation,  together  with a fair rate of interest,  if any, to be paid upon
the amount  determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors,  including the rate of
interest which the surviving or resulting  corporation  would have had to pay to
borrow money  during the pendency of the  proceeding.  Upon  application  by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion,  permit discovery
or other pretrial  proceedings and may proceed to trial upon the appraisal prior
to the final  determination  of the  stockholder  entitled to an appraisal.  Any
stockholder  whose name appears on the list filed by the  surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates  of stock to the  Register in Chancery,  if such is  required,  may
participate fully in all proceedings  until it is finally  determined that he is
not entitled to appraisal rights under this section.

         (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto.  Interest may be simple or compound, as the Court
may direct.  Payment shall be so made to each such  stockholder,  in the case of
holders of  uncertificated  stock  forthwith,  and the case of holders of shares
represented  by  certificates  upon  the  surrender  to the  corporation  of the
certificates  representing  such stock.  The  Court's  decree may be enforced as
other decrees in the Court of Chancery may be enforced,  whether such  surviving
or resulting corporation be a corporation of this State or of any state.

         (j) The  costs of the  proceeding  may be  determined  by the Court and
taxed upon the parties as the Court deems equitable in the  circumstances.  Upon
application  of a  stockholder,  the Court  may  order  all or a portion  of the
expenses   incurred  by  any   stockholder  in  connection  with  the  appraisal
proceeding,  including,  without limitation,  reasonable attorney's fees and the
fees and  expenses of experts,  to be charged pro rata  against the value of all
the shares entitled to an appraisal.

                                       4.

<PAGE>


         (k) From and after the effective  date of the merger or  consolidation,
no stockholder  who has demanded his appraisal  rights as provided in subsection
(d) of this  section  shall be entitled to vote such stock for any purpose or to
receive  payment  of  dividends  or other  distributions  on the  stock  (except
dividends or other  distributions  payable to  stockholders  of record at a date
which is prior to the effective date of the merger or consolidation);  provided,
however,  that if no petition  for an  appraisal  shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation,  either within 60
days after the  effective  date of the merger or  consolidation  as  provided in
subsection  (e) of this section or thereafter  with the written  approval of the
corporation,  then the fight of such  stockholder  to an appraisal  shall cease.
Notwithstanding the foregoing,  no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder  without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

         (l) The shares of the surviving or resulting  corporation  to which the
shares  of such  objecting  stockholders  would  have  been  converted  had they
assented to the merger or consolidation  shall have the status of authorized and
unissued shares of the surviving or resulting corporation.  (Last amended by Ch.
299, L. '96, eff. 2-1-96 and Ch. 349, L. '96. eff. 7-1-96.)

                                     PART II


                     INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20.  Indemnification of Directors and Officers.


     The Company's Certificate of Incorporation contains a provision,  permitted
by Section  102(b)(7) of the Delaware  General  Corporation  Law (the  "Delaware
Law"),  eliminating  the personal  liability of a director to the Company or its
stockholders  for monetary damages for breach of fiduciary duties as a director,
except for  liability  (i) for breach of the  director's  duty of loyalty,  (ii)
under  Section  174 of the  Delaware  Law  (concerning  the  illegal  payment of
dividends by a  corporation),  (iii) for acts or omissions  not in good faith or
which involve  intentional  misconduct or a knowing violation of law or (iv) for
any transaction from which the director derived an improper personal benefit.

     Section 145 of the Delaware Law permits, subject to certain conditions, the
indemnification of directors or officers of a Delaware  corporation for expenses
(including  attorney's  fees),  judgments,  fines and amounts paid in settlement
incurred in  connection  with the defense of any action,  suit or  proceeding in
relation to certain matters against them as such directors or officers.  Article
VI of the Company's By-laws generally  provides that the Company shall indemnify
its officers and directors in accordance with the provisions of Section 145.

     A  third-party  insurance  carrier has agreed to reimburse  the Company for
losses  resulting from certain  liabilities for wrongful acts or matters claimed
against  officers  or  directors  by reason of their  status as such,  including
liabilities that may arise in connection with certain sales of securities by the
Company.

     2.1     Agreement  and Plan of Merger  dated as of August 18, 1997  between
             URS  Corporation,  Woodward-Clyde  Group,  Inc. and W-C Acquisition
             Corporation,  filed  with  the  Commission  as  Exhibit  2.1 to the

             by reference.

     4.1     Certificate of Incorporation  of the Company,  filed as Exhibit 3.1
             to the  Company's  Annual  Report on Form 10-K for the fiscal  year
             ended  October  31,  1991 (the  "1991 Form  10-K"),  filed with the

Item 22.  Undertakings.

     (A)

         (a) The undersigned registrant hereby undertakes:

                                      II-3.

<PAGE>


             (1) To file,  during any period in which  offers or sales are being
made, a post-effective amendment to this registration statement:

                  (i) To include any prospectus  required by Section 10(a)(3) of
the  Securities  Act of 1933,  as amended  (the  "Securities  Act")  (unless the
information  required  to be  included  in a  post-effective  amendment  by this
paragraph is contained in periodic  reports filed by the registrant  pursuant to
Section 13 or Section 15(d) of the  Securities  Exchange Act of 1934, as amended
(the "Exchange Act"),  that are  incorporated by reference in this  registration
statement).

                  (ii) To reflect in the  prospectus any facts or events arising
after the  effective  date of the  registration  statement  (or the most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement  (unless the information  required to be included in a  post-effective
amendment  by this  paragraph  is  contained  in periodic  reports  filed by the
registrant  pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration  statement).  Notwithstanding the
foregoing,  any increase or decrease in the volume of securities offered (if the
total  dollar  value of  securities  offered  would not  exceed  that  which was
registered) and any deviation from the low or high end of the estimated  maximum
offering  range  may be  reflected  in the  form of  prospectus  filed  with the
Securities and Exchange  Commission (the  "Commission")  pursuant to Rule 424(b)
if, in the aggregate,  the changes in volume and price  represent no more than a
20% change in the maximum aggregate offering price set forth in the "Calculation
of Registration Fee" table in the effective registration statement.

                  (iii) To include any material  information with respect to the
plan of distribution not previously  disclosed in the registration  statement or
any material change to such information in the registration statement.

             (2) That,  for the purpose of determining  any liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

             (3) To  remove  from  registration  by  means  of a  post-effective
amendment  any of the  securities  being  registered  which remain unsold at the
termination of the offering.

         (b) The undersigned  registrant hereby undertakes that, for purposes of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Exchange Act that is  incorporated  by reference in the  registration  statement
shall be deemed to be a new  registration  statement  relating to the securities
offered therein, and the offering of such securities at the time shall be deemed
to be the initial bona fide offering thereof.

         (g)

             (1) The undersigned  registrant hereby undertakes as follows:  that
prior to any public  reoffering of the securities  registered  hereunder through
use of a  prospectus  which  is a part of this  registration  statement,  by any
person or party who is deemed to be an  underwriter  within the  meaning of Rule
145(c),  the issuer undertakes that such reoffering  prospectus will contain the
information  called  for by the  applicable  registration  form with  respect to
reofferings  by  persons  who may be deemed  underwriters,  in  addition  to the
information called for by the other Items of the applicable form.

             (2) The  registrant  undertakes  that every  prospectus (i) that is
filed pursuant to paragraph (1) immediately preceding,  or (ii) that purports to
meet the  requirements of section  10(a)(3) of the Securities Act and is used in
connection with an offering of securities  subject to Rule 415, will be filed as
a part of an amendment to the registration  statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective  amendment shall be deemed to
be a new registration  statement relating to the securities offered therein, and
the offering of such  securities  at that time shall be deemed to be the initial
bona fide offering thereof.

         (h)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act may be permitted to directors,  officers and controlling  persons
of the  registrant  pursuant to the  foregoing  provisions,  or  otherwise,  the
registrant  has  been  advised  that  in  the  opinion  of the  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

     (B) The undersigned registrant hereby undertakes to respond to requests for
information  that is incorporated  by reference into the prospectus  pursuant to
Items 4, 10(b),  11, or 13 of this Form,  within one  business day of receipt of
such  request,  and to send the  incorporated  documents  by first class mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

     (C) The undersigned  registrant  hereby  undertakes to supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

                                      II-4.

URS Corporation
100 California Street, 5th Floor
San Francisco, CA  94111

Ladies and Gentlemen:

We have  acted as  counsel  to you,  URS  Corporation,  a  Delaware  corporation
("URS"),  in connection with the transactions  contemplated by the Agreement and
Plan of Merger dated as of August 18, 1997 (the "Merger  Agreement")  among URS,
Woodward-Clyde  Group, Inc., a Delaware  corporation ("WC"), and W-C Acquisition
Corporation ("Acquisition Corp."), a wholly-owned subsidiary of URS, pursuant to
which WC will be merged with and into Acquisition  Corp. (the "Merger") and each
outstanding  share of WC  common  stock  will be  converted  into  the  right to
receive, in the aggregate, $91,693,870, consisting of $26,693,870 in cash and up
to  5,200,000  shares,  par value  $0.01 per  share,  of URS  common  stock (the
"Shares").

In connection  with the Merger,  URS is filing with the  Securities and Exchange
Commission  (the  "Commission")  a  registration  statement  on  Form  S-4  (the
"Registration  Statement")  to register  under the  Securities  Act of 1933,  as
amended, the Shares to be issued under the terms of the Merger Agreement.

We have examined a copy of the Merger  Agreement,  the  Registration  Statement,
your  Certificate  of  Incorporation  and  Bylaws,  as  amended,  and such other
documents,  records,  certificates,  memoranda and other  instruments as we deem
necessary  as a basis for this  opinion.  We have  assumed the  genuineness  and
authenticity  of all documents  submitted to us as originals,  the conformity to
originals  of all  documents  submitted  to us as  copies  thereof,  and the due
execution and delivery of all  documents  where due execution and delivery are a
prerequisite to the effectiveness thereof.

On the basis of the foregoing,  and in reliance  thereon,  we are of the opinion
that the Shares,  when  issued  under the terms of the Merger  Agreement  and as
contemplated   by  the  Joint   Proxy   Statement/Prospectus   included  in  the
Registration Statement, will be validly issued, fully paid, and nonassessable.

We do not  purport  to render an opinion  based on the laws of any  jurisdiction
other  than the  corporate  laws of the State of  Delaware,  and we  express  no
opinion as to the effect of any other laws.

URS Corporation
100 California Street, Suite 500
San Francisco, CA 94111-5239                                 WEBB B. MORROW III
                                                             415 693-2170
Ladies and Gentlemen:                                        [email protected]

This opinion is being delivered to you in accordance with the Agreement and Plan
of  Merger  dated  August  18,  1997  (the  "Plan of  Merger")  by and among URS
CORPORATION,  a Delaware corporation ("Parent"),  W-C ACQUISITION CORPORATION, a
Delaware  corporation and wholly owned  subsidiary of Parent ("Merger Sub"), and
WOODWARD-CLYDE GROUP, INC., a Delaware corporation (the "Company").  The Company
will  merge  with and into  Merger Sub (the  "Merger")  pursuant  to the Plan of
Merger and related  Merger  Documents  (collectively,  including the exhibits to
each, the "Agreements").

   
Except as  otherwise  provided,  capitalized  terms not defined  herein have the
meanings  set forth in the Plan of Merger or in certificates  dated  October 10,
1997 delivered to us by Parent,  Merger Sub and the Company  containing  certain
representations  of Parent,  Merger Sub and the Company  (the  "Certificates  of
Representations").  All section references,  unless otherwise indicated,  are to
the Internal Revenue Code of 1986, as amended (the "Code").
    

We have acted as counsel to the Parent in connection  with the Merger.  As such,
and for the purpose of  rendering  this  opinion,  we have  examined  originals,
certified  copies or copies  otherwise  identified to our  satisfaction as being
true copies of the original of the following  documents  (including all exhibits
and schedules attached thereto):

         (a)      the Agreements;

         (b)      the Certificates of Representations; and

         (c) such other  instruments  and  documents  related to the  formation,
organization and operation of Parent,  Merger Sub and the Company and related to
the consummation of the Merger and the transactions  contemplated  thereby as we
have deemed necessary or appropriate.

In  connection  with  rendering  this  opinion,  we have  assumed  (without  any
independent investigation or review thereof):

         1. Original documents (including  signatures) are authentic,  documents
submitted to us as copies  conform to the original  documents,  and there is (or
will be prior to the Closing) due execution and delivery of all documents  where
due execution and delivery are a prerequisite of the effectiveness thereof;

URS Corporation

         2.  The  truth   and   accuracy   at  all   relevant   times,   of  all
representations,  warranties and statements made or agreed to by Parent,  Merger
Sub and the  Company,  their  management,  employees,  officers,  directors  and
stockholders in connection  with the Merger,  including but not limited to those
set forth in the  Agreements  (including the exhibits) and the  Certificates  of
Representations;  and  that  all  covenants  contained  in such  agreements  are
performed without waiver or breach of any material provision thereof;

         3.  There  is no  plan  or  intention  on the  part  of  the  Company's
stockholders (a "Plan") to engage in a sale, exchange,  transfer,  distribution,
pledge, or other  disposition  (including a distribution by a corporation to its
stockholders)  or any  transaction  which  results  in a  reduction  of  risk of
ownership,  or a direct or indirect  disposition  (a "Sale") of shares of Parent
Common  Stock to be  received  in the  Merger  that  would  reduce  the  Company
stockholders'  ownership of Parent  Common Stock to a number of shares having an
aggregate  fair  market  value,  as of the  Effective  Time,  of less than fifty
percent  (50%) of the  value  of all of the  stock  of the  Company  outstanding
immediately  prior to the Merger.  Shares of the Company  stock with  respect to
which  dissenters'  rights are exercised in the Merger,  which are exchanged for
cash in lieu of  fractional  shares  of Parent  Common  Stock or which are sold,
redeemed or disposed of in a transaction  that is in contemplation of or related
to  the  Merger  shall  be  considered  shares  of the  Company  stock  held  by
stockholders of the Company immediately before the Merger which are exchanged in
the Merger for shares of Parent Common Stock which are then disposed of pursuant
to a Plan;

         4.  Shares of stock of the Company  surrendered  pursuant to the Merger
will  not be  subject  to any  liability  at the  time  surrendered  and that no
liabilities  of any  stockholder  of the  Company  will be  assumed by Parent or
Merger Sub in connection with the Merger; and

         5. Any  representation  or statement made "to the best of knowledge" or
similarly qualified is correct without such qualification.

Based on our examination of the foregoing items and subject to the  limitations,
qualifications,  assumptions and caveats set forth herein, we are of the opinion
that for federal income tax purposes:

         A. The Merger will be a  reorganization  within the meaning of Sections
368(a)(1)(A) and 368(a)(2)(D) of the Code;

         B.  Parent,  Merger  Sub  and the  Company  are  all  "parties"  to the
reorganization within the meaning of Section 368(b) of the Code;

URS Corporation

         C.  Stockholders of the Company who receive part stock and part cash in
the Merger will recognize gain in the amount of such cash, limited,  however, by
such stockholder's total gain on the Merger (which is the difference between the
fair  market  value  of the  Parent  Common  Stock  and  cash  received  by such
stockholder in the Merger less such  stockholder's  basis in such  stockholder's
Company stock exchanged  therefor).  A  stockholder's  recognized gain should be
capital  if such  Company  stock was held as a capital  asset at the time of the
Merger,  provided  that the  payment  is  neither  essentially  equivalent  to a
dividend  within the  meaning of Section 302 of the Code nor has the effect of a
dividend within the meaning of Section  356(a)(2) of the Code  (collectively,  a
"Dividend Equivalent Transaction").  If a loss, rather than a gain, results from
the  application  of the  stockholder's  cost  basis for the  stock  surrendered
against the total consideration received, that loss will not be recognized;

         D. The  aggregate  tax basis of any Parent  Common Stock  received by a
Company  stockholder  in the  Merger  (including  any  fractional  share  deemed
received as  described in  paragraph F below)  generally  should be equal to the
adjusted basis of the Company stock surrendered in exchange  therefor,  less the
cash received in the Merger, plus the gain recognized by such stockholder in the
Merger (if any);

         E. The holding  period (for  capital gain  purposes)  for each share of
Parent  Common Stock  received in the Merger  should  include the period  during
which the share of Company  stock  surrendered  in exchange  therefor  was held,
provided  that such  share of Company  stock was held as a capital  asset at the
time of the Merger;

         F. A  fractional  share of  Parent  Common  Stock not  actually  issued
pursuant to the Merger but for which cash is received in lieu thereof  should be
treated  as a  fractional  share of Parent  Common  Stock  that is issued in the
Merger and then redeemed by Parent. A Company stockholder receiving cash in lieu
of a fractional  share generally  should recognize gain or loss upon the payment
thereof equal to the difference (if any) between such stockholder's basis in the
fractional share and the amount of cash received.  Such gain or loss should be a
capital gain or loss if, at the time of the Merger,  the  stockholder's  Company
stock is held as a capital asset;

         G. A Company stockholder who exercises appraisal rights with respect to
shares of Company  stock and receives a cash  payment for such shares  generally
should recognize capital gain or loss (if such share was held as a capital asset
at the time of the Merger) measured by the difference  between the stockholder's
basis in such share and the amount of cash received,  provided that such payment
is not a  Dividend  Equivalent  Transaction.  A sale of  shares  pursuant  to an
exercise  of  appraisal  rights  generally  will  not be a  Dividend  Equivalent
Transaction  if,  as a  result  of such  exercise,  the  stockholder  exercising
appraisal rights owns no shares of capital

stock of Parent (either actually or constructively within the meaning of Section
318 of the Code) immediately after the Merger;

         H. Parent and Merger Sub will not recognize gain or loss as a result of
the Merger; and

         I. The  Company  will  not  recognize  gain or loss as a result  of the
Merger.

In addition to your request for our opinion on these specific federal income tax
law matters,  you have asked us to review the  discussion of federal  income tax
issues contained in the S-4 Registration  Statement filed in connection with the
Merger  ("Registration  Statement").  We have reviewed the  discussion  entitled
"Certain  Federal  Income  Tax  Considerations"  contained  in the  Registration
Statement and believe that such information  fairly presents the current federal
income  tax  law  applicable  to  the  Merger  and  the  material   federal  tax
consequences  to  Parent,   Merger  Sub  and  the  Company,  and  the  Company's
stockholders as a result of the Merger.

This  opinion  does  not  address  the  various  state,  local  or  foreign  tax
consequences  that may  result  from the  Merger.  In  addition,  no  opinion is
expressed  as to any  federal  income tax  consequence  of the Merger  except as
specifically  set forth  herein,  and this opinion may not be relied upon except
with respect to the consequences specifically discussed herein.

No opinion is expressed as to any transaction other than the Merger as described
in the Agreements or to any other transaction whatsoever including the Merger if
all  the  transactions  described  in the  Agreements  are  not  consummated  in
accordance  with the terms of the  Agreements and without waiver of any material
provisions  thereof.  To the  extent  any of  the  representations,  warranties,
statements and assumptions material to our opinion and upon which we have relied
are not  complete,  correct,  true and accurate in all material  respects at all
relevant times, our opinion would be adversely affected and should not be relied
upon.

This  opinion only  represents  our best  judgment as to the federal  income tax
consequences of the Merger and is not binding on the Internal Revenue Service or
the courts. The conclusions are based on the Code,  existing judicial decisions,
administrative regulations and published rulings. No assurance can be given that
future  legislative,  judicial or  administrative  changes  would not  adversely
affect the accuracy of the conclusions stated herein. Nevertheless, by rendering
this  opinion,  we  undertake  no  responsibility  to  advise  you  of  any  new
developments  in the  application  or  interpretation  of the federal income tax
laws.

         Re:   Agreement and Plan of Merger, dated August 18, 1997, by and among
               URS  Corporation,   a  Delaware   corporation,   W-C  Acquisition
               Corporation,  a Delaware  corporation,  and Woodward-Clyde Group,
               Inc., a Delaware corporation

Ladies and Gentlemen:

   
         We have acted as special tax counsel to Woodward-Clyde  Group,  Inc., a
Delaware corporation (the "Company"),  with respect to the Agreement and Plan of
Merger  dated  August 18,  1997 (the "Plan of Merger")  and entered  into by and
among  URS  Corporation,   a  Delaware   corporation  ("URS"),  W-C  Acquisition
Corporation, a Delaware corporation and wholly owned subsidiary of URS ("WCAC"),
and the Company. Pursuant to the Plan of Merger, the Company will merge with and
into WCAC (the  "Merger")  in  accordance  with the Plan of Merger  and  related
Merger  Documents  (collectively,  including  the exhibits to each,  the "Merger
Agreement").  This opinion is being rendered pursuant to your request. Except as
otherwise  provided,  capitalized terms not defined herein have the meanings set
forth in the Plan of Merger or in certificates  dated October 10, 1997 delivered
to us by URS, WCAC and the Company  containing  certain  representations of URS,
WCAC and the Company (the "Certificates of Representations").
    

         In connection with this opinion, we have examined and are familiar with
originals or copies,  certified or otherwise identified to our satisfaction,  of
the Plan of Merger and such  other  documents  as we have  deemed  necessary  or
appropriate  in  order  to  enable  us to  render  the  opinion  below.  In  our
examination,  we have  assumed  the  genuineness  of all  signatures,  the legal
capacity of all natural persons,  the authenticity of all documents submitted to
us as originals, the conformity to original documents of all documents submitted
to us as certified,  conformed or photostatic copies and the authenticity of the
originals of such  copies.  In  rendering  the opinion set forth below,  we have
relied upon certain written  representations  and covenants of the Company,  URS
and WCAC, which are annexed hereto, and upon representations and facts set forth
in the Plan of Merger.  Further,  our opinion assumes that the Merger will occur
fully in  accordance  with the terms and  provisions  of the Plan of Merger  and
there is (or will be prior to

the Closing) due execution and delivery of all documents where due execution and
delivery are a prerequisite of the effectiveness thereof.

         In rendering our opinion, we have considered the applicable  provisions
of the  Internal  Revenue  Code of  1986,  as  amended  (the  "Code"),  Treasury
regulations,  pertinent  judicial  authorities,   interpretive  rulings  of  the
Internal  Revenue  Service  and such  other  authorities  as we have  considered
relevant.  The opinions set forth below are also  predicated upon and limited by
the assumptions set forth herein and are further subject to the  qualifications,
assumptions, exceptions and limitations set forth below:

         (a) The  opinions and  conclusions  set forth herein are based upon the
federal  income  tax laws of the  United  States,  including  the  Code,  final,
temporary and proposed  Treasury  regulations,  and judicial and  administrative
interpretations  thereof as they exist on the date of this letter.  There can be
no assurance that the legal authorities upon which our opinion is based will not
be modified, revoked, supplemented or otherwise changed, and no assurance can be
given that future  legislative,  judicial  or  administrative  changes  will not
adversely affect the accuracy of the conclusions stated herein. To the extent of
any such changes,  our opinion is not applicable.  Furthermore,  we undertake no
obligations  to  reexamine or in any way revise our opinion in the light of such
changes,  or otherwise  advise you of any new developments in the application or
interpretation of the federal income tax laws which might relate to the opinions
expressed herein.

         (b) This opinion only  represents  our best  judgment as to the federal
income tax consequences of the Merger and is not binding on the Internal Revenue
Service or the courts.

         (c)  There  is no  plan  or  intention  on the  part  of the  Company's
stockholders (a "Plan") to engage in a sale, exchange,  transfer,  distribution,
pledge, or other  disposition  (including a distribution by a corporation to its
stockholders)  or any  transaction  which  results  in a  reduction  of  risk of
ownership,  or a direct or  indirect  disposition  (a  "Sale")  of shares of URS
Common  Stock to be  received  in the  Merger  that  would  reduce  the  Company
stockholders'  collective  ownership  of URS Common  Stock to a number of shares
having an aggregate  fair market value,  as of the Effective  Time, of less than
fifty percent (50%) of the value of all of the stock of the Company  outstanding
immediately  prior to the Merger.  Shares of the Company  stock with  respect to
which  dissenters'  rights are exercised in the Merger,  which are exchanged for
cash in lieu of  fractional  shares  of URS  Common  Stock  or which  are  sold,
redeemed or disposed of in a transaction  that is in contemplation of or related
to  the  Merger  shall  be  considered  shares  of the  Company  stock  held  by
stockholders of the Company immediately before the Merger which are

exchanged in the Merger for shares of URS Common  Stock which are then  disposed
of pursuant to a Plan.

         (d) The shares of Common Stock of the Company  surrendered  pursuant to
the Merger will not be subject to any liability at the time surrendered and that
no liabilities of any  stockholder of the Company will be assumed by URS or WCAC
in connection with the Merger.

         (e) Any  representation or statement made "to the best of knowledge" or
similarly qualified is correct without such qualification.

         Based upon and subject to the  foregoing,  we are of the  opinion  that
under current law:

               1. The Merger will  constitute a tax-free  reorganization  within
the meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the Code;

               2.  URS,   WCAC  and  the  Company  are  all   "parties"  to  the
reorganization within the meaning of Section 368(b) of the Code;

               3.  Stockholders  of the Company who receive  part stock and part
cash in the Merger  will  recognize  gain in the  amount of such cash,  limited,
however,  by the total  gain  realized  by such  stockholder  as a result of the
Merger (which is the difference  between the fair market value of the URS Common
Stock  and  cash  received  by  such   stockholder   in  the  Merger  less  such
stockholder's basis in such stockholder's  Company stock exchanged therefor).  A
stockholder's  recognized  gain should be capital if such Company stock was held
as a capital  asset at the time of the  Merger,  provided  that the  payment  is
neither  essentially  equivalent to a dividend within the meaning of Section 302
of the Code nor has the  effect of a  dividend  within  the  meaning  of Section
356(a)(2) of the Code (collectively, a "Dividend Equivalent Transaction").  If a
loss,  rather than a gain,  is realized  as a result of the  application  of the
stockholder's  cost basis for the Company  stock  surrendered  against the total
consideration received, that loss will not be recognized;

               4. The aggregate tax basis of any URS Common Stock  received by a
Company  stockholder  in the  Merger  (including  any  fractional  share  deemed
received as  described in  Paragraph 6 below)  generally  should be equal to the
adjusted basis of the Company stock surrendered in exchange  therefor,  less the
cash received in the Merger, plus the gain recognized by such stockholder in the
Merger (if any);

               5. The holding  period (for federal income tax purposes) for each
share of URS Common  Stock  received  in the Merger  should  include  the period
during which the share of Company  stock  surrendered  in exchange  therefor was
held,  provided  that such share of Company stock was held as a capital asset at
the time of the Merger;

               6. A fractional  share of URS Common  Stock not  actually  issued
pursuant to the Merger but for which cash is received in lieu therefor should be
treated as a  fractional  share of URS Common Stock that is issued in the Merger
and then  redeemed  by URS. A Company  stockholder  receiving  cash in lieu of a
fractional  share  generally  should  recognize  gain or loss  upon the  payment
thereof equal to the difference (if any) between such stockholder's basis in the
fractional share and the amount of cash received.  Such gain or loss should be a
capital gain or loss if, at the time of the Merger, the Company stock is held as
a capital asset;

               7. A Company  stockholder  who  exercises  appraisal  rights with
respect to shares of Company  stock and  receives  cash  payment for such shares
generally  should  recognize  capital  gain or loss (if such share was held as a
capital asset at the time of the Merger) measured by the difference  between the
stockholder's basis in such share and the amount of cash received, provided that
such payment is not a Dividend Equivalent Transaction. A sale of shares pursuant
to an exercise of appraisal rights  generally will not be a Dividend  Equivalent
Transaction  if,  as a  result  of such  exercise,  the  stockholder  exercising
appraisal  rights  owns no shares of capital  stock of URS  (either  actually or
constructively  within the meaning of Section 318 of the Code) immediately after
the Merger;

               8. URS and WCAC  will not  recognize  gain or loss as a result of
the Merger; and

               9. The Company will not recognize gain or loss as a result of the
Merger.

         In addition to your request for our opinion on this specific  matter of
federal  income tax law, you have asked us to review the  discussion  of federal
income  tax  issues  contained  in  the  S-4  Registration  Statement  filed  in
connection  with the Merger  ("Registration  Statement").  We have  reviewed the
discussion entitled "Certain Federal Income Tax Considerations" contained in the
Registration  Statement and believe that such  information  fairly  presents the
current federal income tax law applicable to the Merger and the material federal
tax consequences to URS, WCAC and the Company, and the Company's stockholders as
a result of the Merger.

         This opinion does not address the various  state,  local or foreign tax
consequences  that may  result  from the  Merger.  In  addition,  no  opinion is
expressed  as to any  federal  income tax  consequence  of the Merger  except as
specifically  set forth  herein,  and this opinion may not be relied upon except
with respect to the consequences specifically discussed herein.

         No opinion is expressed as to any transaction  other than the Merger as
described in the Agreements or to any other transaction whatsoever including the
Merger if all the  transactions  described in the Agreements are not consummated
in  accordance  with the  terms of the  Agreements  and  without  waiver  of any
material  provisions  thereof.  To  the  extent  any  of  the   representations,
warranties, statements and assumptions material to our opinion and upon which we
have  relied  are not  complete,  correct,  true and  accurate  in all  material
respects at all  relevant  times our opinion  would be  adversely  affected  and
should not be relied upon.
