                        PROXY STATEMENT / PROSPECTUS

                             GENERAL INFORMATION

    This Proxy Statement / Prospectus is furnished (1) in connection with the
solicitation by Greiner of proxies to be voted at the Annual Meeting of
Stockholders of Greiner (the "Greiner Meeting") to be held on Tuesday, March
26, 1996 at the Doubletree Hotel at Park West, 1590 LBJ Freeway, Dallas, Texas
75234, at 11:00 a.m., local time, with respect to (a) the Merger of URS
Acquisition Corporation, a Nevada corporation and wholly-owned subsidiary of
URS, with and into Greiner pursuant to the terms and conditions of that certain
Agreement and Plan of Merger among Greiner, URS and URS Acquisition Corporation
(the "Merger Agreement"), dated January 10, 1996, and (b) the election of
directors of Greiner to serve if the Merger is not consummated for any reason,
and (2) as the Prospectus of URS covering the issuance of shares of URS common
stock, par value $.01 per share ("URS Common Stock"), to the stockholders of
Greiner pursuant to the Merger.  All information herein with respect to URS has
been furnished by URS, and all information herein with respect to Greiner has
been furnished by Greiner.  Capitalized terms not otherwise defined herein have
the meanings assigned to such terms in the Merger Agreement.

    As a result of the Merger, Greiner will become a wholly-owned subsidiary of
URS.  Each share of Greiner common stock, par value $.50 per share ("Greiner
Common Stock"), issued and outstanding immediately prior to the Effective Time
of the Merger (as defined in the Merger Agreement) will be converted into the
right to receive $13.50 in cash plus 0.298 shares of URS Common Stock,
representing an aggregate amount of approximately $64,000,000 and approximately
1,400,000 shares of URS Common Stock.  The consideration to be delivered in the
Merger is referred to herein as the "Merger Consideration."  The closing of the
Merger will occur promptly after the satisfaction of the conditions precedent
contained in the Merger Agreement.  All options outstanding at the Effective
Time of the Merger that were issued under the 1981 Stock Option Plan of Greiner
or under the 1991 Stock Option Plan of Greiner (collectively, the "Greiner
Options") will be cancelled; provided, however, that the holders of Greiner
Options will be entitled to receive a cash payment equal to the excess, if any,
between the value of the per share Merger Consideration, based on the closing
price per share of URS Common Stock as quoted in The Wall Street Journal on the
trading day immediately preceding the Closing Date, over the exercise price of
the option.  See "The Merger - The Merger Agreement"; "The Merger - Merger
Consideration;" "The Merger - Effective Time of the Merger."

    As a result of the Merger, former stockholders of Greiner will hold
approximately 16% of the issued and outstanding shares of URS Common Stock.

    SEE "RISK FACTORS" FOR A DISCUSSION OF CERTAIN MATTERS WHICH SHOULD BE
CONSIDERED BY THE STOCKHOLDERS OF GREINER WITH RESPECT TO THE MERGER.

    This Proxy Statement / Prospectus and the accompanying form of proxy are
first being mailed to stockholders of Greiner on or about February 23, 1996.

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

    NEITHER THE MERGER NOR THE SECURITIES OF URS TO BE ISSUED IN CONNECTION
WITH THE MERGER HAVE BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT / PROSPECTUS.  ANY REPRESENTATION
TO THE CONTRARY IS A CRIMINAL OFFENSE.

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

                                    including that URS and Greiner meet
                                    specified financial tests, that there have

                                    respective businesses of URS and Greiner,
                                    and that all conditions precedent to the

Amendment . . . . . . . . . . .     The Merger Agreement may be terminated at
                                    any time prior to the Effective Time by the
                                    written mutual consent of URS and Greiner
                                    or by either party if (i) Greiner
                                    stockholder approval is not obtained, (ii)
                                    a condition precedent to the terminating
                                    party's obligation to consummate the Merger
                                    is not fulfilled or (iii) the other party
                                    breaches a material representation,

                                    contained in the Merger Agreement.  In the
                                    event that either party terminates the
                                    Merger Agreement because of a breach of any
                                    of the foregoing by the other party, and in
                                    the event such breach is the result of
                                    negligence, the damages recoverable by the
                                    non-breaching party shall not exceed the
                                    sum of $500,000; but, provided, further,
                                    that in the event that such breach is the
                                    result of recklessness or willful conduct,
                                    the amount of damages shall not be limited.
                                    See "The Merger-The Merger Agreement."

                                    The Merger Agreement may be amended by the
                                    parties' Boards of Directors prior to
                                    approval of the Merger Agreement by Greiner
                                    stockholders; after Greiner stockholder
                                    approval has been obtained, no amendment
                                    that by law requires the approval of the
                                    Greiner stockholders may be made without
                                    first obtaining such approval.  See "The
                                    Merger - The Merger Agreement."

                                    In the event that Greiner or any of its
                                    officers or directors enter into any
                                    negotiations or discussions for any reason
                                    which shall constitute a breach of the
                                    no-shop provision of the Merger Agreement,
                                    Greiner has agreed to immediately reimburse
                                    URS for all expenses and costs incurred by
                                    URS in connection with the Merger.  In the
                                    event that Greiner 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 Greiner during the
                                    period prior to the Closing or within nine
                                    months after termination of the Merger
                                    Agreement for any reason, Greiner has
                                    agreed to pay URS a termination fee of
                                    $5,000,000.  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  . . . . . . . . . .     A Greiner stockholder who exchanges Greiner
                                    Common Stock for URS Common Stock and cash
                                    generally will recognize income or gain to
                                    the extent the cash and the fair market
                                    value of the URS Common Stock received as
                                    Merger Consideration exceeds the Greiner
                                    stockholder's adjusted tax basis in the
                                    Greiner Common Stock surrendered in the
                                    exchange.  The Merger is not intended to
                                    constitute a tax-free "reorganization"

                                    Internal Revenue Code of 1986, as amended
                                    (the "Code").  See "The Merger - Certain

Effect of Merger for Performance
Plan Participants . . . . . . .     At the Effective Time of the Merger, shares
                                    of Greiner Common Stock held in participant
                                    accounts by the Greiner Performance Plan
                                    will be converted into shares of URS Common
                                    Stock and cash on the same basis as other
                                    shares of Greiner Common Stock.  No federal
                                    or state income tax will be currently due
                                    from Greiner Performance Plan participants
                                    with respect to any gain realized from

Following the Merger  . . . . .     The management of URS after the Merger will
                                    not change, except that after the Effective
                                    Time of the Merger, Mr. Robert L. Costello
                                    will become a director and executive
                                    officer of URS.  See "The Merger -
                                    Directors and Executive Officers After the

              RECOMMENDATION OF THE BOARD OF DIRECTORS OF GREINER

Approval by the Board . . . . .     The Greiner Board has unanimously approved
                                    the Merger Agreement and the Merger and
                                    determined that the Merger is in the best

                                    considered by the Greiner Board in reaching
                                    its decision, see "The Merger - Reasons for
                                    the Merger; Recommendations of the Board of
                                    Directors of Greiner."

Fairness Opinion  . . . . . . .     Among the factors considered by the Greiner
                                    Board in approving the Merger was the
                                    receipt of the opinion of Houlihan Lokey
                                    Howard & Zukin ("Houlihan Lokey") that the
                                    consideration to be received by the public
                                    stockholders of Greiner in connection with
                                    the Merger is fair to them from a financial
                                    point of view.  See "The Merger Agreement -
                                    Greiner Financial Advisor" and Appendix A
                                    -- Fairness Opinion of Houlihan Lokey
                                    Howard & Zukin.

                                    annual election of directors to serve if
                                    the Merger is not consummated for any
                                    reason.  THE GREINER BOARD RECOMMENDS THAT

(1)      During 1995, Greiner initiated various activities to restructure
         certain of its operations in order to reduce its cost structure and
         improve future profitability, resulting in $3,700,000 of restructuring
         charges.  Also in 1995, Greiner reduced the carrying value of its

                   SELECTED PRO FORMA COMBINED FINANCIAL DATA


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

    The unaudited pro forma combined condensed balance sheets as of October 31,
1995 assume that the Merger occurred as of that date.  The unaudited pro forma
combined condensed statement of operations for the twelve months ended October
31, 1995 assumes that the Merger occurred as of November 1, 1994.  In order to
present comparable data for the combining companies, the pro forma statement of
operations includes the historical data for Greiner for the twelve month period
ended December 31, 1995.

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

    Set forth below is certain common share data of URS and Greiner on an
historical basis, a pro forma basis for URS and an equivalent pro forma basis
for Greiner.  The URS pro forma data was derived by combining historical
consolidated financial information of URS and Greiner, giving effect to the
Merger under the purchase method of accounting for business combinations.  The
equivalent pro forma data for Greiner was calculated by multiplying the URS pro 
forma per common share data by the exchange ratio of .298.

    This information should be read in conjunction with the historical
financial statements of URS and Greiner included elsewhere in this Proxy
Statement/Prospectus and the unaudited pro forma combined condensed financial
information included elsewhere in the Proxy Statement/Prospectus.

                                DIVIDEND POLICY

         URS has not paid cash dividends since 1986 and intends to continue to
retain its earnings for investment in its business for the foreseeable future.
Pursuant to the 8-5/8% Indenture, the Unsecured Credit Agreement and the
Secured Credit Agreement, the declaration of dividends, except stock dividends
by URS, is restricted.

         Greiner commenced paying a cash dividend on its Common Stock in the
fourth quarter of 1988.  Annual cash dividends of $.30 and $.28 per share of
Greiner Common Stock were declared and paid in 1995 and 1994, respectively.

                       THE GREINER STOCKHOLDERS' MEETING

PLACE, TIME, AND DATE OF GREINER MEETING

         The Annual Meeting of the Stockholders of Greiner (the "Greiner
Meeting") will be held on Tuesday, March 26, 1996, at 11:00 a.m., local time,
at the Doubletree Hotel at Park West, 1590 LBJ Freeway, Dallas, Texas  75234.

PURPOSE OF THE GREINER MEETING

         Approval of the Merger.  At the Greiner Meeting stockholders will be
asked to consider and vote upon a proposal by the Board of Directors of Greiner
to approve the Merger of Acquisition Corp. with and into Greiner, pursuant to
which each of the outstanding shares of Greiner Common Stock will be converted
into the right to receive 0.298 shares of URS Common Stock and $13.50 in cash.
As a result of the Merger, Greiner will become a wholly-owned subsidiary of URS
and holders of Greiner Common Stock will become stockholders of URS.

         THE BOARD OF DIRECTORS OF GREINER RECOMMENDS A VOTE BY THE GREINER
STOCKHOLDERS FOR APPROVAL OF THE MERGER.

         Election of Directors.  The Greiner Meeting will also include the
annual election of directors to serve if the Merger does not close or is
delayed for any reason.  Pursuant to the authority granted in Greiner's
Restated Articles of Incorporation and Bylaws, the Board has determined that
five directors be elected at the Greiner Meeting to serve until the next annual
meeting and until their successors are elected and have nominated for election
as directors the persons identified at "Annual Election of Greiner Board of
Directors - Nominees for the Greiner Board of Directors."  If, by reason of
death or other unexpected occurrence, any one or more of the nominees should
for any reason become unavailable for election, the persons named as proxies in
the accompanying form of proxy may vote for the election of such substitute
nominees, and for such term or terms, as the Board of Directors may propose.
All of the nominees were elected to the Board of Directors at the last Annual
Meeting, except for Robert L. Costello, who was elected by action of the Board
in July 1995.

         THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR EACH NOMINEE FOR
THE  BOARD OF DIRECTORS.

VOTE REQUIRED

         The affirmative vote of the holders of a majority of the outstanding
shares of Greiner Common Stock entitled to vote thereon is required for the
approval of the Merger.  The favorable vote of the holders of a majority of the
outstanding Greiner Common Stock present at the Greiner Meeting in person or by
proxy is required for election of each director.  Participants in the Greiner
Performance Plan will be asked to direct the Trustees as to how to vote the
Greiner Common Stock allocated to their accounts.  Shares as to which no
direction is received will be voted in accordance with the recommendation of an
adviser retained by the Trustees.  The executive officers and directors of
Greiner own or have the power to vote 14.13% of the 4,704,642 issued and
outstanding shares entitled to vote on the Merger.

         Abstentions and broker nonvotes will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business
at the meeting.  Abstentions are counted to determine the total number of votes
cast and will be counted as a vote against the election of directors, but will
not count as votes for or against approval of the Merger.  Broker nonvotes are
not counted as votes cast for purposes of determining whether a proposal has
been approved and will have no effect on the outcome of the election of
directors.  Because a majority vote of all issued and outstanding shares of
Greiner Common Stock which are eligible to be voted is required to approve the 
Merger, a broker nonvote will have the same effect as a vote against approval 
of the Merger.

         As of the date of this Proxy Statement / Prospectus, 4,704,642 shares
of Greiner Common Stock were outstanding.  In the Merger Agreement, Greiner has
agreed not to issue any additional shares of Greiner Common Stock or other
ownership interests in Greiner prior to the Effective Date, other than pursuant
to the exercise of vested stock options.


                                      12
<PAGE>   20
         Each holder of Greiner Common Stock will be entitled to one vote, in
person or by proxy, for each share standing in his or her name on the books of
Greiner on the Record Date on any matter submitted to a vote of the Greiner
stockholders.

REVOCABILITY OF PROXIES

         A Proxy for use at the Greiner Meeting is enclosed with the definitive
Proxy Statement/Prospectus mailed to Greiner stockholders.  A Greiner
stockholder executing and returning a proxy may revoke it at any time before
the vote is taken by filing with the Secretary of Greiner a written revocation
of the Proxy or a duly executed Proxy bearing a later date than the Proxy being
revoked, or such stockholder may revoke the Proxy in person at the Greiner
Meeting, at any time before the vote is taken, by electing to vote at such
meeting.  All shares represented by a properly executed Proxy, unless such
Proxy previously has been revoked, will be voted in accordance with the
directions on such Proxy.  IF NO DIRECTIONS ARE GIVEN TO THE CONTRARY ON SUCH
PROXY, THE SHARES REPRESENTED BY SUCH PROXY WILL BE VOTED FOR THE MERGER AND
FOR EACH NOMINEE FOR THE GREINER BOARD OF DIRECTORS.  It is anticipated that no
matters will be presented at the Greiner Meeting other than as set forth in the
notice of the Greiner Meeting.

COST OF SOLICITING PROXIES

         The expense of preparing, printing and mailing this Proxy Statement /
Prospectus and the material used in this solicitation of Proxies from Greiner
stockholders will be borne by Greiner.  It is contemplated that Greiner Proxies
will be solicited through the mail, but officers, directors and employees of
Greiner may solicit Proxies personally for the Greiner Meeting.  Greiner has
retained D. F. King, Inc. to assist in the solicitation of proxies and has
agreed to pay D. F. King, Inc. $5,000, plus out of pocket expenses, for such
services.  Greiner has agreed that under certain circumstances it will be
liable for URS's transaction costs if the Merger is not consummated due to
Greiner's breach of the Merger Agreement.  See "The Merger - The Merger
Agreement."

RECORD DATE

         The close of business on February 22, 1996 has been fixed as the
record date ("Record Date") for the purpose of determining the Greiner
stockholders entitled to notice of and to vote at the Greiner Meeting.

DISSENTERS' RIGHTS

         Under Nevada law, holders of Greiner Common Stock will not have the
right to seek a judicial appraisal of the fair value of their shares of Greiner
Common Stock in connection with the proposed Merger.  See "The Merger - Rights
of Dissenting Stockholders."

                                  RISK FACTORS

         The following risk factors should be considered carefully by the
stockholders of Greiner in evaluating the Merger.  These risk factors should be
considered in conjunction with the other information included in this Proxy
Statement / Prospectus.

IMPACT OF MERGER FINANCING

         To finance the Merger, and to provide for working capital needs, URS
has obtained a secured credit facility consisting of $50 million in term loans
maturing in 2002 and 2003 and a $20 million revolving line of credit to
terminate in 1999.  As a result, following the Merger, URS will be a more
highly leveraged company with substantial future debt service requirements.  To
meet these debt service requirements, URS and Greiner must generate sufficient
cash flow from operations or other sources.  There is no assurance that the
future operations of URS and Greiner will provide sufficient funds to meet
these debt service needs and other operational requirements of URS and Greiner
necessary for continued success.

GREINER'S REPORTED LOSSES DURING 1995

         Greiner's 1995 consolidated financial statements reflect significant
pre-tax charges related to the following items.   First, Greiner incurred
substantial operating losses in 1995 from its California residential land
development operations.  In 1995, Greiner management decided to discontinue
these operations and recorded restructuring charges of $1,700,000 in addition
to operating losses of approximately $1,400,000 during 1995.  Second, during
1995, Greiner recorded a one-time write-off of goodwill of $1,500,000
associated with the discontinued California residential land development
operations.  Third, Greiner recorded $500,000 in  restructuring charges during
1995 in connection with the downsizing of its Hong Kong operations resulting
from Greiner's shift of its center of operations in Asia from Hong Kong to
Malaysia.  Fourth, in 1995, Greiner took a non-cash write down of $2,300,000 on
its investment in NTA, a general partnership in which Greiner holds a 50%
general partnership interest.  While there is no assurance of the future
financial performance of Greiner, management believes that the majority of
losses experienced during 1995 result primarily from non-recurring situations
and such losses will not have a significant impact on an ongoing basis;
however, Greiner's reported losses may negatively impact the value of URS
Common Stock after the Merger.

LEGAL PROCEEDINGS/LIABILITY INSURANCE COVERAGE

         Certain subsidiaries of each of Greiner and URS have been named as
defendants in legal proceedings wherein substantial damages are claimed.  Such
proceedings are not uncommon in their businesses and usually involve claims
against multiple defendants who were involved in the project which is the
subject of the proceeding.  Historically, each company has been successful in
defending such actions or has settled them within insured limits.  In the
opinion of management of each company, based upon their present knowledge, the
ultimate liability, if any, in these proceedings is not expected to exceed
amounts previously provided for in the consolidated financial statements.
Because of the nature of the professional services provided and the size and
nature of many of the projects upon which such services are performed, the
potential for claims in excess of insurance limits always exists.  Should that
occur, and if the resulting liability is material, then the operations and
financial condition of URS and Greiner after the Merger would be adversely
affected.  It is also possible that a large number of claims in any given year
could cause the total amount paid with respect to the deductible amounts
relating to such claims to be material, in which event Greiner's and URS's
operations and financial condition could be adversely affected.

   
         Greiner.  In 1995, Greiner was notified by the staff (the "Staff") of
the Central Regional Office of the Securities and Exchange Commission (the
"SEC") that it planned to recommend that a subsidiary of Greiner be named as a
respondent in an administrative action relating to the issuance of certain
revenue bonds used to finance the construction of the new Denver International
Airport.  The subsidiary was a member of a joint venture formed for the sole 
purpose of acting as the program management consultant for the City and County
of Denver on the new Denver International Airport project.  The joint venture
was dissolved at the completion of the project.  The Staff recommendation
relates to certain information about the airport project provided by the
subsidiary to the City and County of Denver in connection with the related bond
offerings. The subsidiary has disputed the Staff's recommendations.
    





                                      14
<PAGE>   22
Management does not anticipate that the resolution of this matter will have a
material effect on Greiner's operations or financial condition.

         Greiner presently carries professional liability insurance against
claims resulting from its alleged negligent performance of professional
services, with an aggregate limit of $30,000,000 per year in excess of an
aggregate $1,000,000 annual self-insured retention and a deductible of $250,000
per occurrence.  This insurance, consistent with industry practice, is on a
"claims made" basis, which means coverage must be in place when a claim is
made.  In addition, such insurance is subject to standard exclusions, including
exclusions for claims arising out of actual, alleged or threatened discharge,
dispersal, seepage, migration, release or escape of pollutants and the
performance of or failure to perform professional services rendered in the
abatement, replacement or removal of any product, material or process
containing asbestos.   The continued availability and cost of professional
liability insurance will depend upon market conditions, the claims record of
Greiner and the claims experience of the insurers providing such coverage.

         URS.  URS has $31,000,000 per occurrence and aggregate commercial
general liability insurance coverage.  URS is also insured for professional
errors and omissions ("E&O"), environmental impairment liability ("EIL") and
contractor pollution liability ("CPL") claims with an aggregate limit of
$25,000,000 after a self-insured per-claim deductible of $500,000.  The E&O,
EIL 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 management's intent to maintain this type of
coverage for its and Greiner's businesses after the Merger, but there can be no
assurance that URS can maintain its insurance coverage or that claims will not
exceed the amount of insurance coverage.

DEPENDENCE UPON GOVERNMENT PROGRAMS AND CONTRACTS

         Both Greiner and URS derive more than 80% of their revenues from
local, state and Federal government agencies.  The demand for engineering
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.  The
success and further development of URS and Greiner is dependent, in significant
part, upon the continued existence and funding of such programs and upon URS
and Greiner'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 (especially
in light of the budget constraints currently existing at all levels of
government), that such programs will continue to be funded even if governments
have available financial resources, or that URS and Greiner will continue to be
awarded contracts under such programs. 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, to
which both URS and Greiner are a party, 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 Greiner's and URS's services are billed on
either a "cost-plus" or a "fixed-price" basis.  Under cost-plus contracts, the
rates for direct and indirect costs are negotiated and fixed before work
commences.  Under fixed-price contracts, the entire contract price is often
fixed before work commences.  Frequently, proposals are submitted on extremely
complex projects that will be performed over the course of several years,
making the accurate forecasting of costs very difficult.  In the recent past,
URS and Greiner have  experienced low profit margins or losses on a  portion of
both of their 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.

ATTRACTION AND RETENTION OF QUALIFIED PROFESSIONALS

         The ability to retain and expand the staff of qualified technical
professionals will be an important factor in determining the future success of
URS and Greiner.  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





                                      15
<PAGE>   23
there can be no assurance that URS and Greiner will continue to be successful
in their efforts to attract and retain such professionals.  In addition, both
companies rely heavily upon the experience and ability of their senior
management staff and the loss of a significant portion of such individuals
could have a material adverse effect upon the companies.

CONTROL OF URS BY PRINCIPAL STOCKHOLDERS

         Richard C. Blum is a director of URS and the majority stockholder of
Richard C. Blum & Associates, Inc., a California corporation ("RCBA, Inc.").
RCBA, Inc. is the sole general partner of Richard C. Blum & Associates, L.P., a
California limited partnership ("RCBA, L.P."), which, in turn, is the sole
general partner of BK Capital Partners, a California limited partnership
("BK"), BK Capital Partners II, a California limited partnership ("BK II"), and
BK Capital Partners III, a California limited partnership ("BK III").  RCBA,
L.P. is an investment adviser to The Common Fund, an investment fund.  BK, BK
II, BK III and The Common Fund collectively hold 2,472,693 shares (assuming the
exercise of certain warrants by only these entities), or approximately 34
percent, of the URS Common Stock outstanding prior to the effectiveness of the
Merger and approximately 28 percent of the URS Common Stock which would be
outstanding after the effectiveness of the Merger.  RCBA, L.P. exercises voting
and investment discretion as to all such shares.

                                  THE MERGER

         This section of the Proxy Statement / Prospectus contains information
furnished by the Board of Directors of URS and by the Board of Directors of
Greiner in connection with the Greiner Meeting for the purpose of obtaining
stockholder approval of the Merger.

         A copy of the Merger Agreement is attached as Appendix B and
incorporated herein by reference.  The Merger Agreement contains certain
representations and covenants of URS, Acquisition Corp. and Greiner, 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 shall 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.  ALL GREINER STOCKHOLDERS
ARE URGED TO READ THE MERGER AGREEMENT IN ITS ENTIRETY.

GENERAL

         The Merger Agreement provides for the merger of Acquisition Corp. into
Greiner, with Greiner as the surviving corporation.  Upon consummation of the
Merger, each outstanding share of Greiner Common Stock will be converted into
the right to receive (i) 0.298 shares of URS Common Stock, and (ii) $13.50 in
cash, with additional cash to be paid in lieu of fractional shares.  If the
Merger is completed, Greiner stockholders will no longer hold any interest in
Greiner other than indirectly through their interest in the shares of URS
Common Stock.  Each outstanding share of URS Common Stock will remain
outstanding and unchanged following the Merger.  Holders of Greiner Common
Stock will receive an aggregate of approximately 1,400,000 shares of URS Common
Stock upon consummation of the Merger and will hold in the aggregate
approximately 16% of the URS Common Stock outstanding immediately after
consummation of the Merger.

         All Greiner Options outstanding at the Effective Time of the Merger
will be cancelled; provided, however, that the holders of Greiner Options will
be entitled to receive a cash payment equal to the excess, if any, of the value
of the per share Merger Consideration, based on the closing price per share of
URS Common Stock as quoted in The Wall Street Journal on the trading day
immediately preceding the Closing Date, over the exercise price of the option.
See "The Merger - Merger Consideration."


EFFECTIVE TIME OF THE MERGER

         The Merger will become effective (the "Effective Time of the Merger")
upon the filing of articles of merger or other appropriate documents (in any
such case, the "Merger Documents") with the Nevada 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 by the Greiner 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.  The Merger Agreement may
be terminated by either URS or Greiner if the Merger has not become effective
on or before September 30, 1996 (unless the failure to consummate the Merger by
such date is due to the action or failure to act of the party seeking to
terminate the Merger Agreement in breach of such party's obligations
thereunder).

MERGER CONSIDERATION

         Conversion of Greiner Common Stock.  At the Effective Time of the
Merger, Acquisition Corp. will merge with and into Greiner, with Greiner as the
surviving corporation.  The Articles of Incorporation and Bylaws of Greiner as
in effect immediately prior to the Effective Time of the Merger will be the
Articles of Incorporation and Bylaws of the surviving corporation until further
amended as provided therein and in accordance with law.  At the Effective Time
of the Merger, each outstanding share of Greiner Common Stock will be converted
into the right to receive (i) 0.298 shares of URS Common Stock and (ii) $13.50
in cash, with additional cash to be paid in lieu of





                                      17
<PAGE>   25
fractional shares.  At the Effective Time of the Merger, Greiner stockholders
will no longer hold any interest in Greiner other than indirectly through their
interest in the shares of URS Common Stock.  Each outstanding share of URS
Common Stock will remain outstanding and unchanged following the Merger.
Holders of Greiner Common Stock will receive an aggregate of approximately
1,400,000 shares of URS Common Stock upon consummation of the Merger and will
hold in the aggregate approximately 16% of the URS Common Stock outstanding
immediately after consummation of the Merger, based on the number of shares of
URS Common Stock outstanding at February 14, 1996.  Each share of Acquisition
Corp. common stock outstanding immediately prior to the Effective Time of the
Merger will be converted into one share of a newly-created class of $1.00 par
value common stock of Greiner (the surviving corporation), and Greiner will
become a wholly-owned subsidiary of URS.

         Greiner Stock Options.  All Greiner Options outstanding at the
Effective Time of the Merger will be cancelled; provided, however, that the
holders of Greiner Options will be entitled to receive a cash payment in an
amount per share of Greiner Common Stock subject to his or her Greiner Option
equal to the excess, if any, of the value of the per share Merger
Consideration, based on the closing price per share of URS Common Stock as
quoted in The Wall Street Journal on the trading day immediately preceding the
Closing Date, over the exercise price per share with respect to the option.  In
addition, instead of receiving the cash payment described above, each holder 
of a Greiner Option has the right to exercise vested options prior to the 
Effective Time of the Merger and purchase Greiner Common Stock, in which case 
each share of Greiner Common Stock received pursuant to the option will be 
exchanged pursuant to the Merger for the Merger Consideration.

         Greiner Performance Plan and Employee Stock Ownership Plan.  At the 
Effective Time of the Merger, The Performance Plan and Stock Ownership Plan of
Greiner (the "Greiner Performance Plan") will be amended to cease to be an 
employee stock ownership plan ("ESOP") within the meaning of Section 4975(e)(7)
of the Code, but will be continued as a profit sharing plan, subject to the 
terms of the Greiner Performance Plan document regarding amendment and/or 
termination. Cash proceeds received by the Greiner Performance Plan in 
connection with the Merger will not be reinvested in URS Common Stock or 
Greiner Common Stock, but will be reinvested in the various investment options 
available under the non-ESOP portion of the Greiner Performance Plan, as 
directed by plan participants, and employer stock will no longer be one of the 
investment options offered under the Greiner Performance Plan.  URS Common 
Stock received by Greiner Performance Plan accounts in connection with the 
Merger will continue to be held by the Greiner Performance Plan, but no 
additional investments in URS Common Stock will be permitted.  In addition, in 
the event that as of the Effective Time of the Merger the aggregate value of 
the unvested ESOP portion of the Greiner Performance Plan accounts is less than
$1,000,000 (valuing such unvested shares of Greiner Common Stock at an amount 
equal to the closing price of the Greiner Common Stock as reported on the NYSE 
on the trading day immediately preceding the Closing Date, as quoted in The 
Wall Street Journal), all plan participants will be fully vested in their ESOP
accounts as of the Effective Time of the Merger.

CONVERSION AND EXCHANGE OF GREINER COMMON STOCK CERTIFICATES

         As soon as practicable after the Effective Time of the Merger, First
Interstate Bank, the Exchange Agent (the "Exchange Agent"), will send a notice
and transmittal form to each holder of Greiner Common Stock of record at the
Effective Time of the Merger advising such holder of the effectiveness of the
Merger and the procedure for surrendering to the Exchange Agent their
certificates formerly evidencing Greiner Common Stock.  GREINER STOCKHOLDERS
SHOULD NOT SEND THEIR STOCK CERTIFICATES TO THE EXCHANGE AGENT OR GREINER 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 Greiner Common 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 Greiner
Common 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 Greiner Common Stock certificate
was registered only if (i) the Greiner Common 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.

BACKGROUND OF THE MERGER

         From time to time beginning in March of 1993, URS and Greiner
management held informal discussions about the possibility of a transaction
between the two companies.  Until November of 1995, these informal discussions
did not result in any agreement regarding a transaction between the parties.

         In early November of 1995, senior management of URS met with its
financial advisors regarding the advisability of developing an offer to acquire
Greiner.  On November 20, 1995, a special meeting of the URS Board of Directors
was held to discuss the possibility of authorizing URS management to present an
acquisition proposal to Greiner management.  The URS Board of Directors
authorized URS management to proceed with the presentation of an acquisition
proposal to Greiner management.  The Board of Directors also authorized URS
management to contact Wells Fargo Bank, National Association ("Wells Fargo") to
initiate discussions about providing financing for the transaction.

         On November 30, 1995, Martin Koffel, the Chief Executive Officer,
President and Chairman of URS, met with Robert Costello, the Chief Executive
Officer of Greiner.  Mr. Koffel presented an outline to Mr. Costello describing
proposed terms by which URS would offer to acquire Greiner.  On December 1,
1995, Mr. Costello and Messrs. William Bowen and Russell Cleveland, both
directors of Greiner, placed a call to Mr. Koffel to discuss the proposed terms
of the offer (Messrs. Costello, Bowen and Cleveland comprise the Executive
Committee of the Board of Directors).  After discussion, a revised proposal was
sent to Mr. Costello.

         On December 2, 1995, a proposed letter of intent and draft joint press
release with respect to the proposed transaction were prepared and reviewed by
URS and its advisors, and then transmitted to Greiner.  Further discussions
regarding these documents and the terms of the transaction continued throughout
the day between URS and its advisors and Greiner.

         On December 3, 1995, a letter of intent was signed and the wording of
a joint press release was prepared.  The joint press release was issued prior
to the opening of trading on the NYSE on December 4, 1995.

         On January 9, 1996, the Merger Agreement was approved by the Boards of
Directors of Greiner, URS and Acquisition Corp.  The Merger Agreement was
executed by all parties thereto on January 10, 1996.  In addition, on January
10, 1996, URS entered into a $70 million secured credit facility with Wells
Fargo, which consists of $50 million in term loans maturing in 2002 and 2003,
and a $20 million revolving line of credit.  See "The Merger - Financing of the
Merger."

GREINER FINANCIAL ADVISOR

         Greiner has engaged Houlihan Lokey to render an opinion to the Greiner
Board of Directors as to the fairness of the terms of the Merger to the Greiner
public stockholders, from a financial point of view.  Houlihan Lokey is a
diversified financial advisory and specialty investment banking firm with
offices in Los Angeles, New York, Chicago, San Francisco, Minneapolis,
Washington, D.C., Dallas and Toronto.  Houlihan Lokey offers business and
securities valuations, fairness and solvency opinions, financial restructuring
advice, dispute analysis and liquidation support, merchant banking services and
investment banking services, including merger and acquisition representation
and private placement of capital.

         On January 10, 1996, Houlihan Lokey delivered to the Greiner Board of
Directors its written opinion dated January 10, 1996 (the "Houlihan Lokey
Opinion") that, based upon and subject to the matters set forth in the opinion,
the consideration to be received by the public stockholders of Greiner in
connection with the Merger is fair to them from a financial point of view.

         The summary of the Houlihan Lokey Opinion set forth in this Proxy
Statement / Prospectus is qualified in its entirety by reference to the full
text of such opinion.  The form of the Houlihan Lokey Opinion is attached
hereto as Appendix A.  HOLDERS OF GREINER COMMON STOCK ARE URGED TO READ THE
HOULIHAN LOKEY OPINION IN ITS ENTIRETY FOR FURTHER INFORMATION AS TO THE
ASSUMPTIONS MADE, MATTERS CONSIDERED AND OTHER ASPECTS OF THE REVIEW BY
HOULIHAN LOKEY.





                                      19
<PAGE>   27
         Houlihan Lokey did not, and was not requested by the Greiner Board of
Directors to, make any recommendations as to the form or amount of
consideration to be paid to the Greiner stockholders in the Merger, which
issues were resolved in arm's length negotiations between Greiner and URS.
Houlihan Lokey did not participate in these negotiations.  Furthermore,
Houlihan Lokey was not requested to, and did not, solicit third party
indications of interest in acquiring all or any part of Greiner.

         In advising Greiner, Houlihan Lokey reviewed and analyzed: (1) the
Merger Agreement; (2) financial and operating information with respect to the
business, operations and prospects of Greiner furnished to it by Greiner; (3)
such publicly available information concerning URS which it deemed to be
relevant to its inquiry, including a recent trading history of URS's Common
Stock; (4) a comparison of the historical financial results and present
financial condition of Greiner with those of other companies which it deemed
relevant; and (5) a comparison of the financial terms of the Merger with the
terms of certain other recent transactions which it deemed relevant.

         In addition, Houlihan Lokey had discussions with certain members of
the senior management of Greiner and URS to discuss the business, operations,
assets, financial conditions and prospects and the potential strategic benefit
to Greiner from a consolidation of the business of Greiner with URS.

         In connection with its review, Houlihan Lokey assumed and relied upon
the accuracy and completeness of the financial and other information used by it
in advising Greiner without independent verification and further relied upon
the assurances of management of Greiner that they were not aware of any facts
that would make such information inaccurate or misleading.

         Greiner decided to retain Houlihan Lokey based on its experience as a
financial advisor in mergers and acquisitions in the engineering industry.  For
Houlihan Lokey's services as financial advisor to Greiner in connection with
the Merger, Greiner has agreed to pay Houlihan Lokey a fee of approximately
$100,000, plus out of pocket expenses.  Greiner also has agreed to indemnify
Houlihan Lokey against certain liabilities under the Federal securities laws
relating to or arising out of services performed by Houlihan Lokey as financial
advisor to Greiner.

         Houlihan Lokey has had two prior formal engagements with Greiner, and
has provided consulting services on one other occasion.  Specifically, Houlihan
Lokey was engaged by Greiner (on behalf of its Employee Stock Ownership Plan)
in August of 1986 in connection with the Greiner ESOP's purchase of Greiner
Common Stock.  In March 1993, Houlihan Lokey provided Greiner with preliminary
consulting services (not under a formal retention agreement), consisting of a
meeting at Greiner's headquarters, regarding a potential acquisition of another
company.  Houlihan Lokey was next retained by Greiner in July 1995 to provide
Greiner with a preliminary analysis of the fair market value of a firm which
Greiner was considering acquiring at that time. Aggregate fees paid to Houlihan
Lokey for these engagements did not exceed $50,000.

REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS OF GREINER

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

1.       The significant premium that URS is paying to Greiner stockholders, as
         substantiated by the Houlihan Lokey Opinion.  In evaluating the offer,
         the Board also considered Greiner'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 URS and
         Greiner 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 and Greiner in
         the top echelon of their industry.

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


                                      20
<PAGE>   28
         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 eliminating certain overlapping expenses.

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

         THE GREINER BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS FAIR TO AND
IN THE BEST INTERESTS OF GREINER AND ITS STOCKHOLDERS.  ACCORDINGLY, THE BOARD
OF DIRECTORS OF GREINER HAS APPROVED THE MERGER AGREEMENT AND RECOMMENDS THAT
THE HOLDERS OF GREINER COMMON STOCK VOTE FOR THE APPROVAL OF THE MERGER.

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 Mr. Robert L. Costello will become a
director and executive officer of URS.  See "URS Management - Executive
Officers of URS - Directors of URS."

REGISTRATION AND LISTING

         The URS Common Stock to be issued in the Merger will be registered
under the Securities Act of 1933 (the "1933 Act").  URS has agreed to prepare
and file with the SEC the Registration Statement and any other documents
required by the 1933 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 the URS Common Stock in
connection with the Merger.

   
         URS filed a listing application with each of the NYSE and
the PSE covering the shares of URS Common Stock which are issuable upon
consummation of the Merger.  The NYSE and the PSE have approved the listing of
such shares upon issuance.

         Pre-Closing Covenants of Greiner.

                 1.       Conduct of Business in Ordinary Course.  Greiner and
         its subsidiaries have agreed to carry on their respective businesses
         in the usual, regular and ordinary course in substantially the same
         manner as heretofore conducted, and, to the extent consistent with
         such businesses, Greiner and its subsidiaries have agreed to use all
         reasonable efforts to preserve intact their present business
         organizations, keep available the services of their present officers
         and employees, and preserve their relationships with customers,
         suppliers and others having business dealings with Greiner and its
         subsidiaries.  In particular, without limitation, Greiner and its
         subsidiaries have agreed that neither Greiner nor any of its
         subsidiaries shall (except with the prior written consent of URS):

                          (i)     accelerate, amend or change the period of
                                  exercisability of vesting of options granted
                                  under any stock option plans or restricted
                                  stock, stock bonus or other awards, or
                                  authorize cash payments in exchange for any
                                  options, restricted stock, stock bonus or
                                  other awards granted under any of such plans;

                          (ii)    grant any severance or termination pay to any
                                  officer or director or, except in the
                                  ordinary course of business consistent with
                                  past practices, to any employee;

                          (iii)   transfer any intellectual property rights 
                                  owned by Greiner;

                          (iv)    commence a lawsuit other than for routine
                                  collection of bills, except in cases where
                                  Greiner in good faith determines that failure
                                  to commence such suit would result in a
                                  material impairment of a valuable aspect of
                                  Greiner's business, or for breach of the
                                  Merger Agreement; or

                          (v)     enter into one or more leases which extend
                                  for a period of two years beyond the date of
                                  the Merger Agreement and which obligate
                                  Greiner or its subsidiary to pay aggregate
                                  gross rent in excess of $500,000.

                 2.       Dividends; Change in Stock.  Greiner has agreed that
         it will not, and it will not permit any of its subsidiaries to, (i)
         declare or pay any dividends on or make other capital distributions in
         respect to any of its capital stock, except for intercompany dividends
         or regular quarterly cash dividends to holders of Greiner Common Stock
         in an amount which shall not exceed $0.075 per share and at times
         consistent with prior practice, (ii) split, combine or reclassify any
         of its capital stock or issue or authorize or propose the issuance of
         any other securities in respect of, in lieu of or in substitution for
         shares of its capital stock, or (iii) repurchase, redeem or otherwise
         acquire, any shares of its capital stock.

                 3.       Issuances of Securities.  Greiner has agreed that it
         will not, and it will not permit any of its subsidiaries to, issue,
         deliver or sell, or authorize or propose the issuance, delivery or
         sale of, any shares





                                      22
<PAGE>   30
         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, or any other ownership
         interests in such capital stock other than the issuance of Greiner
         Common Stock pursuant to the exercise of vested options.

                 4.       Governing Documents.  Greiner has agreed that it will
         not, and it will not cause or permit any of its subsidiaries to, amend
         its Restated Articles of Incorporation or Bylaws.

                 5.       No Acquisitions.  Greiner has agreed that it will
         not, and it will not permit any of its subsidiaries to, acquire, or

         or otherwise dispose of, any of its assets, except for such
         dispositions in the ordinary course of business or in amounts which

         agreed to hold a meeting of its stockholders at the earliest
         practicable date to submit the Merger Agreement and related matters
         for their consideration and approval, and that approval would be
         recommended by Greiner's Board of Directors, subject to their

         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 Greiner, whether through
         purchase, merger, consolidation, exchange or any other business
         combination.  In the event that Greiner or any of its officers or

                 In the event that either party terminates the Merger Agreement
         because of a breach of any of the foregoing by the other party, and in
         the event such breach is the result of negligence, the damages
         recoverable by the non-breaching party shall not exceed the sum of
         $500,000; but, provided, further, that in the event that such breach
         is the result of recklessness or willful conduct, the amount of
         damages shall not be limited hereby.  See "The Merger-The Merger
         Agreement."

                 14.      Maintenance of Business.  Greiner has agreed to 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 of the
         Merger Agreement.  Greiner has agreed that if Greiner becomes aware of
         a deterioration in the relationship with any 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.

                 15.      Access.  Greiner has agreed to 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.

                 16.      Liability Insurance.  Greiner has agreed to procure
         (subject to the approval of URS) continuing directors' and officers'
         liability coverage (tail coverage) for directors and officers of
         Greiner who have served as directors and officers of Greiner or its
         affiliates, prior to the Effective Time of the Merger, with respect to
         acts or failures to act prior to the Effective Time of the Merger.
         Greiner has also agreed to procure continuing fiduciary liability
         coverage (tail coverage) for employees of Greiner who have served as
         fiduciaries under any Greiner Plan prior to the Effective Time of the
         Merger, with respect to acts or failures to act prior to the Effective
         Time of the Merger.

         Pre-Closing Covenants of URS.

                 1.       Registration Statement.   The URS Common Stock to be
         issued in the Merger will be registered under the 1933 Act.  URS has
         agreed to prepare and file with the SEC the Registration Statement and
         any other documents required by the 1933 Act in connection with the
         Merger.  URS has agreed to use its best efforts to have the
         Registration Statement declared effective as promptly as practicable
         after such filing.  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 the URS Common Stock in the Merger.

                 2.       Listing Agreement.  URS has agreed to prepare and
         submit to each of the NYSE and the PSE a listing application covering
         the shares of the URS Common Stock to be issued in connection with the
         Merger.  URS has agreed to use its best efforts to obtain, prior to
         the Effective Time of the Merger, approval for the listing of such URS
         Common Stock, subject to official notice of issuance.

         Termination.  The Merger Agreement may be terminated at any time
before the Merger becomes effective in the following circumstances:

                 1.       By mutual agreement of URS and Greiner;

                 2.       By either URS or Greiner if (i) the approval of the
         Merger by a majority of the outstanding shares of Greiner Common Stock
         is not obtained, (ii) a Governmental Entity shall have issued an
         order, decree or ruling or taken any other actions permanently
         restraining, enjoining or otherwise prohibiting the Merger, or (iii)
         the Merger shall not have been consummated before September 30, 1996
         (provided that the terminating party is not then in material breach of
         any representation, warranty, covenant or agreement contained in the
         Merger Agreement);

                 3.       By URS, if there has been a breach by Greiner of any
         representation, warranty, covenant or other agreement in the Merger
         Agreement which has a Greiner Material Adverse Effect, and such breach
         has not been cured, or Greiner has not commenced reasonable efforts to
         cure such breach, within 30 days after written notice of such breach
         is given by URS to Greiner;

                 4.       By URS if Greiner shall enter into any discussions,
         negotiations or any letter of intent, understanding or other agreement
         relating to an Acquisition Proposal (as defined below);

                 5.       By Greiner if there has been a breach by URS or
         Acquisition Corp. of any material representation, warranty, covenant
         or other agreement, and such breach has not been cured, or URS and
         Acquisition Corp. have not commenced reasonable efforts to cure such
         breach, within 30 days after written notice of such breach is given by
         Greiner to URS; and

                 6.       By either party, if any of the conditions that must
         be satisfied by the other party has not been fulfilled on or prior to
         the date specified for fulfillment thereof, or has become impossible
         to fulfill for reasons beyond the control of the other party, and such
         condition has not been waived.

                 If the Merger Agreement is terminated by either Greiner 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 Greiner, 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), 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; provided,
         however, if the breach is the result of negligence, damages may not
         exceed the sum of $500,000; but, provided, further, if the breach is
         the result of recklessness or willful misconduct, the amount of
         damages will not be limited.

         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 Secured Credit Agreement
provides that URS may not





                                      27
<PAGE>   35
agree to any material amendment to, or waive any of its material rights under,
the Merger Agreement without the prior written consent of the Administrative
Agent (as defined below) for the Lenders under its credit facility.

                 The Merger Agreement may be amended by the parties by action
taken by their respective Boards of Directors at any time prior to or after the
approval of the Greiner stockholders, but after the approval of the Greiner
stockholders has been obtained, no amendment may be made which by law requires
the further approval of the Greiner stockholders without first obtaining such
approval.  The Merger Agreement may not be amended except by a written
instrument signed on behalf of each of the parties.

         Acquisition Proposals; Limitation on Negotiations; Termination Fee.
The Merger Agreement provides that Greiner 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
Greiner, 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 Greiner
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 Greiner'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 Greiner's directors to Greiner's
stockholders.  Greiner has agreed to 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 Greiner 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, Greiner has agreed to immediately reimburse URS for all
expenses and costs incurred by URS in connection with the transactions
contemplated by the Merger Agreement.  In the event that Greiner 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 Greiner, 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, Greiner has agreed to pay to URS a
termination fee (the "Termination Fee") of $5,000,000 dollars; provided,
however, that the Termination Fee will not be payable if, prior to the entry by
Greiner into such letter of intent, understanding or other agreement, URS has
unilaterally declined to close the Merger.  The foregoing provisions of the
Merger Agreement may have the effect of discouraging competing offers to
acquire or merge with Greiner.

         In the event that either party terminates the Merger Agreement because
of a breach of any of the foregoing by the other party, and in the event such
breach is the result of negligence, the damages recoverable by the
non-breaching party shall not exceed the sum of $500,000; but, provided,
further, that in the event that such breach is the result of recklessness or
willful conduct, the amount of damages shall not be limited hereby.  See "The
Merger-The Merger Agreement."

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 "The Merger - Pro Forma Financial Information."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following discussion is for general information only and is based
on the Federal income tax law now in effect, which is subject to change,
possibly retroactively.  This summary does not discuss all aspects of Federal
income taxation which may be important to particular Greiner stockholders in
light of their individual circumstances (e.g., financial institutions,
broker-dealers, insurance companies, tax-exempt organizations and foreign
stockholders).  In addition, there may be state or local tax consequences, none
of which are discussed below.


                                      28
<PAGE>   36
         A Greiner stockholder whose Greiner Common Stock is converted into
shares of URS Common Stock and cash pursuant to the Merger generally will
recognize income (or loss) equal to the difference between (i) the amount of
cash and the fair market value (determined as of the Effective Time of the
Merger) of the URS Common Stock received as Merger Consideration and (ii) the
Greiner stockholder's adjusted tax basis in the Greiner Common Stock so
converted.  The Merger is not intended to constitute a tax-free
"reorganization" within the meaning of Section 368 of the Code.  The
characterization of any such income (or loss) as capital gain (or capital loss)
or ordinary income (or ordinary loss) generally will depend on whether the
Greiner Common Stock surrendered in the exchange is held as a "capital asset"
within the meaning of Section 1221 of the Code.  Any capital gain or loss will
be a long-term capital gain or loss if the exchanging Greiner stockholder is
treated as holding the Greiner Common Stock surrendered in the exchange for
more than one year.  The maximum Federal tax rate applicable to long-term
capital gains of an individual taxpayer is 28%.  Congress is considering
legislation which would reduce this rate but it is uncertain whether any
legislation that is enacted would apply to gain from the Merger recognized by a
Greiner stockholder.  Greiner stockholders will have a tax basis in the URS
Common Stock received in the Merger equal to the fair market value of such URS
Common Stock, determined as of the Effective Time of the Merger.

         A holder of Greiner Options who is paid an amount in connection with
the cancellation of the Greiner Options generally will recognize ordinary
income equal to the amount received.

         Neither the Performance Plan nor the plan participants (as defined in
the Performance Plan) should recognize any Federal tax consequences as a result
of the Merger and the Greiner Performance Plan's ceasing to be an ESOP within
the meaning of Section 4975(e)(7) of the Code.  See "The Merger - Merger
Consideration."

         THE FOREGOING DISCUSSION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES IS
NOT TAX ADVICE AND CONSTITUTES ONLY A GENERAL DESCRIPTION OF CERTAIN OF THE
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO GREINER
STOCKHOLDERS WHO ARE CITIZENS OR RESIDENTS OF THE UNITED STATES, WITHOUT
CONSIDERATION OF THE PARTICULAR FACTS AND CIRCUMSTANCES OF EACH STOCKHOLDER'S
SITUATION.  ACCORDINGLY, EACH STOCKHOLDER IS URGED TO CONSULT HIS OR HER OWN
TAX AND FINANCIAL ADVISORS AS TO MATTERS DESCRIBED HEREIN AND ALSO AS TO ANY
ESTATE, GIFT, STATE OR LOCAL OR FOREIGN TAX CONSEQUENCES ARISING OUT OF THE
MERGER.

REGULATORY APPROVALS

         Under the Merger Agreement, the obligations of URS 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.
Greiner 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, Greiner and URS have agreed to use their best efforts to
obtain it.  There can be no assurance as to whether or when any such other
approval, if required, could be obtained.  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.  Greiner 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 January 4, 1996.

         Form S-4.  The Registration Statement on Form S-4 pertaining to the
URS Common Stock to be issued in connection with the Merger has been filed with
the SEC and been declared effective prior to the mailing of this Proxy
Statement/Prospectus.  The effectiveness of the Merger is conditioned upon the
continued effectiveness of the Registration Statement.

   
         Listing Agreements.  URS filed listing applications with the NYSE 
and the PSE covering the shares of URS Common Stock to be issued in connection
with the Merger.  The NYSE and the PSE have approved the listing of such shares
upon issuance.

RIGHTS OF DISSENTING STOCKHOLDERS

         URS Stockholders.  Based upon the structure of the Merger and under
the Delaware General Corporation Law, URS stockholders will not be called upon
to vote upon the approval of the Merger and will not have any dissenters'
rights with respect to the Merger.

         Greiner Stockholders.  Based upon the structure of the Merger and
under the Nevada General Corporation Law, holders of Greiner Common Stock are
not entitled to dissenters' rights with respect to the Merger.

FINANCING OF THE MERGER

         Generally.  To finance the cash portion of the Merger, URS executed a
Credit Agreement, dated as of January 10, 1996 (the "Secured Credit
Agreement"), by and among URS, as Borrower, the financial institutions listed
therein as Lenders (the "Lenders"), and Wells Fargo, as Administrative Agent
(the "Administrative Agent") for the Lenders, pursuant to which the Lenders are
making the following loans to URS to finance the Merger and to provide for the
working capital needs of URS thereafter:  (i) a $32,500,000 Tranche A term loan
(the "Tranche A Term Loans") maturing on October 31, 2002, with quarterly
principal payments gradually increasing from $500,000 to $1,750,000; (ii) a
$17,500,000 Tranche B term loan (the "Tranche B Term Loans") maturing on April
30, 2003, with nominal quarterly principal payments until October 31, 2002 and
then balloon payments due in January and April 2003; and (iii) a $20,000,000
revolving facility (including a letter of credit facility) (the "Revolving
Loans") expiring April 30, 1999 (the Tranche A Term Loans, the Tranche B Term
Loans and the Revolving Loans are hereinafter collectively referred to as the
"URS Loans").  The URS Loans will be secured by a pledge of the accounts
receivable and general intangibles of URS and its subsidiaries, and of the
stock of URS's subsidiaries.  It is expected that the facility will be
syndicated to include other Lenders following consummation of the Merger.

         Conditions to Initial Funding.  The Lenders' obligation to fund the
URS Loans will expire on May 31, 1996 (the "Initial Funding Date"), provided,
however, that the Initial Funding Date can be extended, in URS's sole
discretion and upon the payment of an increased commitment fee, until September
30, 1996.

         In addition, although the Secured Credit Agreement has been executed,
the Lenders are not obligated to fund the URS Loans until a number of
conditions have been satisfied, including:  URS and Greiner must meet specified
financial performance tests; there must be no material adverse change in the
business of URS or Greiner from the date the Secured Credit Agreement was
executed until the Initial Funding Date; URS and Greiner must each conduct its
business in the ordinary course from the date the Secured Credit Agreement was
executed 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; 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.

         Interest Rates.  URS may select either of the following Wells Fargo
interest rates for the URS loans:  (i) its Base Rate (the higher of the rate
most recently announced by Wells Fargo as its "Prime Rate" or one-half of one
percent in excess of the Federal Funds Effective Rate); or (ii) its Adjusted
Eurodollar Rate.

         Tranche A Term Loans and Revolving Loans bearing interest at the Base
Rate will bear interest at the following rate:  (i) from the Initial Funding
Date until either January 29, 1997 or June 16, 1997 (depending upon when the
Merger takes place), at the Base Rate plus 1.375% per annum; and (ii)
thereafter, at the Base Rate plus a margin (which varies from a high of 1.375%
to a low of 0%) depending upon the ratio of URS's total debt to earnings (i.e.,
the lower the ratio of funded debt to earnings, the lower the rate).  Tranche B
Term Loans bearing interest at the Base Rate will bear interest at the Base
Rate plus 1.75% per annum.

         Tranche A Term Loans and Revolving Loans bearing interest at the
Adjusted Eurodollar Rate will bear interest at the following rate:  (i) from
the Initial Funding Date until either January 29, 1997 or June 16, 1997
(depending upon when the Merger takes place), at the Adjusted Eurodollar Rate
plus 2.625% per annum; and (ii) thereafter, at the Adjusted Eurodollar Rate
plus a margin (which varies from a high of 2.625% to a low of 1.375%) depending
upon the ratio of URS's total debt to earnings (i.e., the lower the ratio of
funded debt to earnings, the lower the rate).  Tranche B Term Loans bearing
interest at the Adjusted Eurodollar Rate will bear interest at the Adjusted
Eurodollar Rate plus 3% per annum.

                        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 Greiner adjusted to
give effect to the Merger using the purchase method of accounting for business
combinations.

         The pro forma combined balance sheet gives effect to the Merger as if
the Merger were effective October 31, 1995.  The pro forma combined condensed
statement of operations has been prepared as if the Merger was effective
November 1, 1994.  In order to present comparable data for the combining
companies, the pro forma statement of operations includes the historical data
of Greiner for the twelve month period ended December 31, 1995.

         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,
1995 and the audited financial statements and notes thereto of Greiner for the
year ended December 31, 1995.  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 YEAR ENDED OCTOBER 31, 1995
                                  (UNAUDITED)

1.  Organization and Basis of Presentation:

         The Merger Agreement described within this Proxy Statement/Prospectus
contemplates the merger of a wholly owned subsidiary of URS with and into
Greiner, after which Greiner will be a wholly owned subsidiary of URS.  Greiner
stockholders will receive $13.50 per share in cash plus 0.298 shares of URS
Common Stock for each outstanding share of Greiner Common Stock.  Based on the
4,704,642 outstanding shares of Greiner Common Stock (net of shares held in
treasury) on the date of this Proxy Statement/Prospectus, the aggregate
consideration will be approximately $64,000,000 in cash and 1,400,000 shares of
URS Common Stock.

         The pro forma financial statements have been prepared based on the
historical financial statements of Greiner, 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 balance
sheet assumes the Merger was consummated on October 31, 1995, and the statement
of operations has been prepared as if the Merger had been consummated on
November 1, 1994.  However, in order to present comparable data for the
combining companies, the pro forma statement of operations includes the
historical data of Greiner for the twelve month period ended December 31, 1995.
These statements should be read in conjunction with the historical financial
statements, and the related notes thereto, incorporated by reference herein.

         The unaudited pro forma financial statements are not necessarily
indicative of what the actual financial position would have been at October 31,
1995, nor of the actual results of operations for the year ended October 31,
1995, had the Merger occurred on October 31, 1995, and November 1, 1994,
respectively, nor does it purport to present the future financial position or
results of operations of URS and Greiner.

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 Greiner as if URS
had acquired Greiner on October 31, 1995 (dollars in thousands).

</TABLE>

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

<TABLE>
           <S>                                            <C>

           Purchase price of Greiner (net of prepaid
               loan fees of $2,000)                       $ 76,487
           Fair value of net assets acquired               (46,954)
                                                          -------- 
           Excess purchase price over net
               assets acquired                            $ 29,533
                                                          ========
</TABLE>

         URS management believes that the amounts reflected on Greiner's
historical consolidated balance sheet as to tangible assets and liabilities
approximate 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.





                                      34
<PAGE>   42
         c.  Fees and expenses related to the Merger are estimated to be
$5,000,000, $2,000,000 of which are associated with the financing of the
transaction.  The financing fees are being capitalized and charged to interest
expense over the term of the loan.  The remaining fees and expenses are being
capitalized as goodwill.

         d.  The pro forma combined condensed balance sheets reflect the
issuance of approximately 1,400,000 shares of URS Common Stock and cash
consideration of $13.50 per Greiner share in exchange for 100% of the shares of
Greiner Common Stock, based upon an assumed URS closing stock price of $7.125
per share.

         e.  Adjustments to reflect: 1) the reductions in public company costs
and expenses of approximately $2,000,000, net of, 2) $1,000,000 of amortization
of goodwill arising from the Merger.

         f.  Adjustment includes interest expense related to debt incurred in
connection with the Merger, and the reduction in interest income incurred as
follows (dollars in thousands):

                                                                ------
             Net                                                $5,990
                                                                ======
</TABLE>

         g.  Subsequent to the Merger, Greiner's operating results will be
included in URS's consolidated tax returns, which results in a pro forma
reduction to the income tax provision of $1,140,000 for the year ended October
31, 1995.

         h.  The pro forma combined loss per share calculation is based upon
the weighted average number of shares of URS Common Stock outstanding, assuming
the issuance of 1,400,000 shares of URS Common Stock pursuant to the Merger.
Common stock equivalents, such as options and warrants, have been excluded from
the calculation as they are anti- dilutive.

INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION

         With the approval of URS, Mr. Costello expects to execute an
employment agreement with Greiner to be effective upon consummation of the
Merger.  Under this agreement, Mr. Costello will (i) be employed by Greiner for
a term of three years from the date the agreement is executed, (ii) receive an
annual base salary of $250,000, and (iii) be entitled to a 40% target bonus
award percentage to be calculated under an incentive compensation plan to be
established by Greiner which will be comparable to URS Consultants, Inc. 1995
Incentive Compensation Plan, with appropriate modifications.  If Mr. Costello's
employment is terminated involuntarily by Greiner without cause (other than by
reason of death or disability), he will be entitled to a severance payment of
one hundred percent (100%) of his annual base compensation (subject to certain
adjustments) and group long-term disability insurance coverage, basic term life
insurance coverage with a death benefit of up to $100,000 and reimbursement of
dental and health insurance premiums for a period of one year after such
termination.  If Mr. Costello is terminated by Greiner other than for cause or
voluntarily leaves for specified reasons within one year following a Change of
Control (as defined in the agreement), Mr. Costello will be entitled to receive
a severance payment equal to two hundred percent (200%) of his then current
base salary.

         Mr. Costello was previously granted options to acquire 49,500 shares
of Greiner Common Stock at exercise prices ranging from $10.38 to $16.00 per
share.  As described generally in "The Merger - Merger Consideration - Greiner
Stock Options" above, like other holders of Greiner options, upon consummation
of the Merger such options will be cancelled and Mr. Costello will be entitled
to receive a cash payment of approximately $137,500 (assuming a per share
Merger Consideration of $15.50 at the Effective Time of the Merger).  Upon
consummation of the Merger, Mr. Costello will also be granted an option to
purchase 50,000 shares of URS Common Stock under the URS Corporation 1991 Stock
Incentive Plan, as amended.

         With the approval of URS, Greiner also expects to offer basic
employment agreements to certain other senior executive officers of Greiner to
become effective upon the consummation of the Merger.  These agreements will
provide for two year employment terms with base salaries at varying levels, and
for a severance payment of one hundred percent (100%) of base salary (subject
to certain adjustments) in the event of involuntary termination, but will not
contain change of control provisions.  At the current time, it is not known how
many senior executive officers will accept such agreement.

         William E. Guthner, Jr., a director of Greiner, is a partner of
Nossaman, Guthner, Knox & Elliott, attorneys at law.  Nossaman, Guthner, Knox &
Elliott represents Greiner in connection with the transactions described herein.

                 ANNUAL ELECTION OF GREINER BOARD OF DIRECTORS

         The Greiner Meeting will include the annual election of directors to
serve if the Merger does not close or is delayed for any reason.  Pursuant to
the authority granted in Greiner's Restated Articles of Incorporation and
Bylaws, the Board has determined that five directors be elected at the Greiner
Meeting to serve until the next annual meeting and until their successors are
elected and have nominated for election as directors the persons identified
below. If, by reason of death or other unexpected occurrence, any one or more of
the nominees should for any reason become unavailable for election, the persons
named as proxies in the accompanying form of proxy may vote for the election of
such substitute nominees, and for such term or terms, as the Board of Directors
may propose.  All of the nominees were elected to the Board of Directors at the
last Annual Meeting, except for Robert L. Costello, who was elected by action of
the Board in July 1995.

NOMINEES FOR THE GREINER BOARD OF DIRECTORS

         The nominees for directors of Greiner, their ages, the period they
have served as directors, the number of shares of Greiner Common Stock that
they beneficially owned, directly or indirectly, and their percentage of
outstanding Greiner Common Stock, at February 6, 1996 are shown below.  Unless
indicated otherwise, beneficial ownership includes both sole voting and sole
investment power.

stockholders provided that such recommendations are accompanied by information
sufficient to enable the Nominating Committee to evaluate the qualifications of
the nominee.  Stockholders wishing to recommend nominees should do so in a

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The Compensation Committee of the Greiner Board of Directors is
charged with the responsibility of reviewing and making recommendations with
respect to compensation and benefit programs for Greiner and its executives.
With regard to executive compensation, it is the philosophy of the Greiner
organization to provide a program which encourages continuous improvements in
our ability to provide quality services for our clients while achieving a level
of financial performance that exceeds the average of our industry peer group
for our stockholders, employees, and the ongoing needs of Greiner.  Greiner's
program is designed to link all compensation for executives to the achievement
of Greiner's immediate and long-term business performance and goals.

         The primary elements of this program are Base Salary, Cash Incentive
Compensation, Stock Options, and participation in standard company benefit
programs such as health and disability insurance and the 401(k)/ESOP which are
available to all employees.  No single element of compensation is awarded
without consideration of the potential total compensation to be paid for the
designated position.

         Base Salary ranges are established for each position, based on the
duties and level of responsibility held, taking into account "market
ranges/rates" for specific positions, verified against similar or like duties
and responsibilities that exist within the market and industry (defined as
professional service firms providing engineering and architectural consulting
services).  Once ranges are established, factors such as local cost-of-living
differences or the movement of the consumer price index have only minor impact
on changes to the person's base compensation.  Adjustments to base compensation
are made based upon assigned responsibility and performance and are measured
against successful attainment of specific goals and objectives of Greiner and
individual employees.

         Greiner believes that Cash Incentive Compensation plays a strong role
in stimulating management actions aimed at achievement of Company profit goals.
Acceptable profit levels shall be determined by the Board of Directors in
consultation with the Compensation Committee and with management of Greiner.
Overall economic conditions, the markets for Greiner's services and other
factors may be taken into consideration when determining such profit levels.
Currently, a minimum level of profit (before taxes and incentives) equal to six
percent of net revenue is necessary to generate a contribution pool for this
plan.

         If a cash incentive pool is generated, it is distributed to executives
upon consideration of individual attainment of Company objectives and upon
review of all aspects of the individual's total compensation package.  All such
awards are reviewed and approved by this Compensation Committee.

         Stock Options are awarded to executives in order to encourage future
management actions aimed at improving Greiner's sales efforts, client service
quality and Company profitability.  If Greiner is successful in improving these
areas, it is anticipated that these actions will generate a positive impact on
the value of Greiner's stock for stockholders, and the individuals will be
given the opportunity to share in the increased value that results from their
efforts.  Specific awards of options are based on the individual's ability to
impact company-wide performance and with consideration of the total
compensation appropriate for the position.

         In establishing compensation levels for Mr. Callahan and Mr. Costello,
consideration was given to individual performance level relative to their role
as Chief Executive Officer, as well as the progress made in meeting strategic
company objectives.  Based on the philosophy of providing a competitive total
compensation package, Mr. Callahan's and Mr. Costello's duties and
responsibilities, actual performance results, and the overall profitability of
Greiner were evaluated and compared to industry norms to determine the total
compensation paid.

         Amounts paid or accrued for fiscal 1995 under these plans for the
Chief Executive Officers and four highest- paid executive officers are
presented elsewhere in this Proxy Statement/Prospectus.  No member of this
committee is a former or current officer or employee of Greiner or any of its
subsidiaries.

         with that of the S&P 500 Composite Index and the weighted performance
         of a peer group of similar engineering companies.  It should be noted
         that many of the companies which provide services similar to Greiner's
         are privately held and therefore are not included in this comparison.
         The peer index of publicly held companies is comprised of Greiner and:
         ICF International, Jacobs Engineering Group, Inc., Michael Baker
         Corporation, STV Group, Inc. and URS Corporation.

         Greiner Engineering, Inc., the S&P 500 Composite Index and the peer
         group, with investment weighted by relative market capitalization.

INDEPENDENT ACCOUNTANTS

         The Board of Directors of Greiner appointed the firm of Price
Waterhouse LLP ("Price Waterhouse") to act as independent accountants for
calendar year 1995.  A representative of Price Waterhouse is expected to be
present at the Greiner Meeting and available to respond to appropriate
questions and, although it has been indicated that no statement will be made,
an opportunity for a statement will be provided.

         Greiner has not selected an independent accountant for 1996 as its
policy is for the Board of Directors to do so after the Annual Meeting each
year.

         The reports of Price Waterhouse on Greiner's financial statements for
each of three years in the period ended December 31, 1995 contained unqualified
opinions.

OTHER MATTERS

    At the time of mailing this Proxy Statement / Prospectus, Greiner was not
aware of any matter not referred to in the form of proxy that would be
presented for action at the meeting.  If, however, any other business shall
properly come before the meeting, it is intended that the shares represented by
proxies will be voted with respect thereto in accordance with the judgment of
the person voting them.

    If the Merger is not consummated for any reason, Greiner's stockholders may
submit proposals for consideration at Greiner's 1997 Annual Meeting of
Stockholders.  Any such proposal must be received by December 1, 1996.

URS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

         Results of Operations.

                 Fiscal 1995 Compared with Fiscal 1994.  Revenues in fiscal
1995 were $179.8 million, or 10% over the amount reported in fiscal 1994.  The
growth in revenues is primarily attributable to increases in revenues derived
from all 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 1995 to $37.1 million as compared to $41.0 million in fiscal 1994.  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.  Revenues generated from private commercial businesses increased
from $16.3 million in fiscal 1994 to $21.1 million in fiscal 1995.

         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 is due to an overall increase in
URS's business in fiscal 1995 as compared to fiscal 1994.  Indirect general and
administrative expenses ("IG&A") increased to $63.2 million in fiscal 1995 from
$55.5 million in fiscal 1994. 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 has available net operating loss
("NOL") carryforwards which partially off-set otherwise taxable income for
Federal income tax purposes, for state income tax purposes such amounts are not
necessarily available to offset income subject to tax.  Accordingly, URS's
effective tax rate for fiscal 1995 was approximately 20%.  This effective
income tax rate is based on URS using a significant portion of the unlimited
NOL available to it in fiscal year 1995.  See "Income Taxes" below and "Note 6 -
Income Taxes" to URS's consolidated financial statements.

         Net income increased to $5.1 million in fiscal 1995 as compared to
$4.4 million in fiscal 1994.  URS earned $.67 per share on a fully-diluted
basis in fiscal 1995 compared to $.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, which are awarded projects for which contracts have not
been signed, was $194.1 million at October 31, 1995, as compared to $172.0
million at October 31, 1994.

                 Fiscal 1994 Compared with Fiscal 1993.  Revenues in fiscal
1994 grew to $164.1 million, or 13%, over the amount reported in fiscal 1993.
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
$41.0 million in fiscal 1994 compared to $38.5 million in fiscal 1993.  The
increase in revenues from these contracts was due to an increase in the number
of task orders for hazardous waste clean-up services.  Revenues generated from
private commercial businesses decreased to $16.3 million from $16.7 million in
fiscal 1993.

         Direct operating expenses, which consist of direct labor and direct
expenses including subcontractor costs, increased $11.0 million, or 12%, over
the amount reported in fiscal 1993.  The increase was due to an overall
increase in URS's business in fiscal 1994 as compared to fiscal 1993.  In
fiscal 1994, IG&A expenses increased to $55.5 million from $51.6 million in
fiscal 1993.  However, expressed as a percentage of revenues, IG&A expenses
decreased from 35% in fiscal 1993 to 34% in fiscal 1994.  URS attributes this
decrease to continued emphasis on cost controls, as well as the one-time charge
of $2.0 million taken in the third quarter of fiscal 1993 in connection with
the planned phase-out of certain of URS's architectural offices and for claims
on certain of URS's architectural projects.  Net interest expense remained
constant at $1.2 million in fiscal 1994 due to significantly lower debt levels
in fiscal 1993 and 1994 as the result of the secondary common stock offering
completed by URS in June 1991.

         URS earned $4.9 million before income taxes in fiscal 1994 compared to
$1.4 million in fiscal 1993.  While URS had available NOL carryforwards which
partially off-set otherwise taxable income for Federal income


                                      43
<PAGE>   51
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 1994 was approximately 9%.

         Net income increased 238% to $4.4 million compared to $1.3 million in
fiscal 1993.  URS earned $.60 per share in fiscal 1994 compared to $.18 per
share in fiscal 1993.

         URS's backlog of signed and funded contracts at October 31, 1994 was
$159.1 million as compared to $142.0 million at October 31, 1993.  The value of
URS's designations, which are awarded projects for which contracts have not
been signed, was $172.0 million at October 31, 1994 as compared to $213.6
million at October 31, 1993.

         Income Taxes.  Prior to October 10, 1989, URS had available NOL
carryforwards for Federal income tax purposes of approximately $51.0 million.
As a result of a change in ownership as defined by Section 382 of the Code that
occurred on October 10, 1989, URS's NOL carryforwards for financial statement
and Federal income tax purposes became limited to approximately $750,000 per
year for the succeeding fifteen-year carryforward period, for an aggregate of
$11.2 million, plus NOL attributable to recognized built-in gains, limited to
$14.0 million by Section 382 of the Code, for a total of $25.2 million.  The
financial statement tax benefits arising from these NOL carryforwards will be
recognized as a reduction in financial statement tax expense and an addition to
paid-in capital in the years utilized.  At October 31, 1995, URS had utilized
$18.4 million of the total $25.2 million for Federal income tax purposes,
including all of the $14.0 million NOL attributable to recognized built-in
gains.  The remaining available NOL is limited to $750,000 per year.

         Effective November 1, 1993, URS adopted the provisions of Statement of
Financial Accounting Standards ("SFAS") Number 109, "Accounting for Income
Taxes."  This standard requires companies to record all deferred tax
liabilities and assets for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax basis, including tax loss
carryforwards.  As permitted under SFAS Number 109, prior years' financial
statements were not restated.  This change did not materially affect URS's
consolidated financial statements.

         Liquidity and Capital Resources.  URS's liquidity and capital
measurements are set forth below:

    As discussed in "Information Concerning URS - Acquisitions" below, on
January 4, 1995, URS acquired E.C. Driver & Associates, Inc. for an aggregate
purchase price of $3,596,000, which was paid in cash.

    In April 1995, URS amended its existing line of credit with Wells Fargo
Bank, National Association (the "Bank"), to be an unsecured line of credit up
to $15,000,000 and expiring April 29, 1997.  Borrowings on the unsecured line
of credit bear interest at the option of URS at a per annum rate equal to
either the Bank's prime rate, or 1.5% over the interest rate offered to the
Bank in the interbank Eurodollar market, adjusted for the Bank's Eurodollar
reserve requirements.  At October 31, 1995, URS had outstanding letters of
credit totaling $386,000, which reduced the amount available to URS under the
unsecured line of credit to $14,614,000.  See Note 7 - Long-Term Debt - Credit
Agreement - to URS's consolidated financial statements.  Under the unsecured
credit agreement, URS is required to satisfy certain financial and
non-financial covenants.  URS was in compliance with all financial and
non-financial covenants contained in the unsecured credit agreement at October
31, 1995 and a predecessor secured credit agreement at October 31, 1994.

    As discussed more fully in "The Merger", on December 3, 1995, URS and
Greiner executed a letter of intent for URS to acquire all the outstanding
stock of Greiner pursuant to a merger of Greiner with a wholly-owned subsidiary
of URS.  To finance the cash portion of this proposed acquisition, URS has
executed the Secured Credit





                                      44
<PAGE>   52
Agreement, as more fully discussed in "The Merger -- Financing of the Merger."
See also Note 7 - Long-Term Debt - Credit Agreement - to URS's consolidated
financial statements.

    URS is a professional services organization and, as such, is not capital
intensive.  Capital expenditures during fiscal years 1995, 1994, and 1993 were
$1,610,000, $2,149,000, and $1,952,000, respectively.  The expenditures were
principally for computer-aided design and drafting equipment and facilities
expansion to accommodate URS's growth.  URS expects fiscal 1996 capital
expenditures to be comparable to the expenditures in fiscal 1995.

    URS believes that its existing financial resources, together with its
planned cash flow from operations and its unused line of credit, as well as
credit facilities provided for in the Secured Credit Agreement, will provide
sufficient capital to fund its operations and its capital expenditure needs for
the forseeable future.

(1)      During 1995, Greiner initiated various activities to restructure
         certain of its operations in order to reduce its cost structure and
         improve future profitability, resulting in $3,700,000 of restructuring
         charges.  Also in 1995, Greiner reduced the carrying value of its
         investment in a partnership by $2,300,000.

             Revenue.  During each of the years 1993 through 1995, Greiner
generated approximately 80%  of its revenue from public sector clients and the
remainder of its revenue from private sector clients.  Greiner reports its
services by division based on the type of client and market for which the
service is performed.  All of Greiner's services are performed in one segment
and are all engineering and architectural services.  In 1995, Greiner expanded
its reporting of divisions to include marine transportation and
federal/military clients.  In previous periods, the marine transportation
division was included with the air transportation division and the
federal/military division was included with the institutional division.
Greiner's total revenue was derived from the following market-focused divisions
in the approximate percentages as shown in the following table:

</TABLE>

         Greiner's gross revenue increased to $154,175,000 in 1995, from
$151,856,000 in 1994, an increase of 1.5%.  The increase in revenue in 1995 is
primarily due to the increased use of subconsultants which permitted a greater
volume of work to be performed by Greiner.  This increase in revenue followed
an increase of 8.0% in 1994.  The 1994 revenue increase was primarily due to
additional contracts resulting from an increased marketing effort.

                 Direct Cost of Revenue.  As a percentage of gross revenue,
Greiner's direct cost of revenue increased to 26.2% in 1995 from 24.6% in 1994
and 23.9% in 1993.  These changes primarily resulted from the increased use of
subconsultants on various projects.  On many projects with public clients,
Greiner is required to have subcontractors complete specified percentages of
the awarded contracts.  This percentage to be completed by


                                      47
<PAGE>   55
subcontractors varies by client and project.  Additionally, Greiner uses
subconsultants on some projects to provide additional engineering services or
other areas of expertise for which Greiner does not have available staff.

                 Salaries and Related Costs.  Salaries and related costs
(payroll taxes, insurance and other fringe) increased slightly in 1995 to 54.0%
of gross revenue from 53.7% in 1994.  This increase relates primarily to
project labor overruns in the California land development and mid-Atlantic
operations, as well as increased indirect labor due to the greater marketing
effort on international projects.  These increases were partially offset by
declines in the employee incentive and insurance expense.  Because of the
operating loss recorded in 1995, there was not a Greiner incentive
contribution.

         In 1994, salaries and related costs declined to 53.7% of gross revenue
from 55.1% in 1993.  This decrease is a result of decreases in the direct labor
incurred to fulfill contract requirements and a decline in the employee
incentive expense.  Salaries and related costs were higher in 1994 over 1993
for marketing pursuits and for indirect activities related to employee
training, quality management and long-term strategic planning.

                 General Expenses.  General expenses increased to 21.5% of
gross revenue in 1995 compared to 17.9% in 1994.  Greiner experienced three
significant increases in general expenses in 1995.  First, Greiner recorded a
$850,000 addition to the allowance for doubtful accounts as a result of
contract and payment disputes related to a contract termination in Hong Kong.
Second, Greiner accrued approximately $600,000 of non-reimbursable expenses
related to the completion of various projects in the California residential
land development operations.  Third, Greiner incurred higher costs related to
contract audit matters, litigation and other contingencies.  Additionally,
depreciation expense increased approximately $700,000 due to continued
upgrading of computer hardware and software, and data processing expense was
higher as fewer of these expenses were directly reimbursable on projects in
1995 compared to 1994.

         In 1994, general expenses increased to 17.9% of gross revenue from
16.4% in 1993.  The primary reasons for this increase were:  higher marketing
and travel expenses resulting from Greiner's expanded international marketing
efforts; increased depreciation expense due to continued upgrading of computer
hardware and software; and increased reserves related to litigation and other
contingencies.

                 Restructuring Charges.  During 1995, Greiner incurred
approximately $3,700,000 of restructuring charges related to the reduction of
operations in Greiner's California residential land development and Hong Kong
operations.  The decision by Greiner to restructure these operations resulted
in the following charges in 1995:  $1,375,000 associated with the closing of
the California residential land development offices and the early termination
or sublease of office leases; additional office exit costs in California of
$85,000; employee severance costs of $240,000 related to the termination of
approximately 30 employees in California; the reduction of the carrying value
of goodwill associated with the California residential land development
operations of $1,500,000; and $500,000 related primarily to lease termination
costs in the restructured Hong Kong operations.  See Note 10 in the Notes to
Consolidated Financial Statements.

                 Partnership Valuation Adjustment.  The National Transportation
Authority ("NTA") -- a general partnership between Greiner and The Perot Group
- - was formed in 1992 to pursue the planning, financing, construction, and
operation of tollroad facilities worldwide, principally through public/private
partnerships.  NTA currently holds the franchise rights for the tollway
extension to State Route 57 (SR 57) in Orange County, California.  To date, NTA
has been unsuccessful in securing necessary financing for the preliminary
environmental phases of the SR 57 project and currently holds no other
significant project franchises.  Although NTA is continuing to pursue financing
alternatives for the SR 57 project and is actively seeking new project
opportunities in public/private transportation projects, the lack of progress
on the SR 57 project has caused Greiner to record a non-cash charge of
$2,300,000 in 1995 to reduce the carrying value of its investment in NTA.  See
Note 4 in the Notes to Consolidated Financial Statements.

                 Other Income.  Other income, consisting primarily of interest
income, remained relatively constant in 1995 compared to 1994.  Other income
increased in 1994 compared to 1993 as a result of the increase in interest
rates on Greiner's investments.

                 Provision (Benefit) For Income Taxes.  The effective income
tax rate for 1995, 1994 and 1993 was (28.4%), 40% and 40% respectively.  The
income tax rate for 1995 reflects deferred tax benefits resulting from





                                      48
<PAGE>   56
the losses recorded during the year, partially offset by permanent differences,
primarily related to the $1,500,000 writeoff of goodwill discussed above.

         Liquidity and Capital Resources.  For internal management purposes,
Greiner reviews, among other things, its working capital, accounts receivable
activity and the percentage of debt to equity on a continuing basis.

Greiner's liquidity and capital measurements are set forth below:

</TABLE>

         The decline in Greiner's working capital and working capital ratio is
primarily a result of the operating losses incurred in 1995, which resulted in
increases in accounts payable and accrued liabilities partially offset by an
increase in current deferred tax benefits.  Also in 1995, Greiner's long-term
investments increased due to the purchase of treasury notes in excess of one
year.  The increase in 1995 in the average days to convert billed accounts
receivable to cash is primarily a result of Greiner's emphasis on accelerating
the billing process which increased billed accounts receivable but
significantly reduced unbilled accounts receivable.  See Note 2 in the Notes to
Consolidated Financial Statements.  In 1995, Greiner paid off all outstanding
debt resulting in the decline in the percentage of debt to equity.

         Greiner's assets include cash and investments in excess of its
day-to-day operating needs.  It is anticipated that a substantial portion of
Greiner's cash will be used to pay the cash portion of the Merger Consideration
to holders of Greiner Common Stock.

         Greiner has an unsecured bank line of credit which aggregates
$15,000,000 and provides for the payment of interest at the lower of the bank's
prime rate or 1-1/2% over the bank's cost of funds rate.  At December 31, 1995,
1994 and 1993, there were no working capital borrowings outstanding.  This line
of credit will be terminated if the merger discussed above is consummated.

         Greiner has had a cash dividend program which provided for cash
dividend payments of $.30, $.28 and $.24 per share of Greiner's outstanding
common stock for 1995, 1994 and 1993, respectively.  Greiner may not pay cash
dividends in 1996 if the proposed merger is completed.

         On March 7, 1995 Greiner's Board of Directors authorized the purchase
of up to 500,000 shares of Greiner's common stock to be held in treasury.
Through December 31, 1995, 127,292 shares of common stock had been purchased to
be held in treasury, of which 6,200 of these shares were released in 1995 for
the exercise of stock options.

         Greiner's operations are professional services and as such are not
capital intensive.  However, in order to enhance productivity, remain
competitive and potentially increase revenue, Greiner has increased its annual
purchases of computer hardware and software.  Greiner presently has no material
commitments for purchases of additional equipment.

                           INFORMATION CONCERNING URS

OVERVIEW

         URS offers a broad range of planning, design and program and
construction management services for engineering, architectural and
environmental projects.  URS serves public and private sector clients
throughout the United States in two principal markets: infrastructure projects
involving transportation systems, institutional and commercial facilities and
water resources, and environmental projects involving hazardous waste
management and pollution control.

   
         URS conducts its business through 24 offices located throughout the
United States.  URS has approximately 1,500 full-time 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.
    

         URS provides professional services through URS's 24 offices in three
major areas: planning, design and program and construction management.  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 two major markets:  (i) infrastructure
projects involving transportation systems, institutional and commercial
facilities and water resources; and (ii) environmental projects involving
hazardous waste management and pollution control.  URS has developed a
nationwide identity based on its successful completion of a number of highly
visible rehabilitation and expansion projects in these markets.  Although URS
views these markets as being distinct, URS provides its planning, design and
program and construction management services to both markets.





                                      50
<PAGE>   58
         Infrastructure.  URS has significant expertise in three areas relating
to the infrastructure market: transportation systems, institutional and
commercial facilities and water resources projects.

                 Transportation Systems.  URS's engineers, designers, planners
         and managers provide services for projects involving all types of
         transportation networks, such as highways, roadways, streets, bridges,
         rapid and mass transit systems, 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 preliminary and final design to construction management.
         Historically, URS's emphasis in this market area has been on the
         design of new transportation facilities, but in recent years the
         rehabilitation of existing facilities 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.

                 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.

         Environmental.  URS has developed expertise in two principal
environmental markets:  hazardous waste management and pollution control.

                 Hazardous Waste Management.  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.

                 URS has been awarded several significant contracts with
         government agencies, including a contract with the U.S. Department of
         Defense for environmental engineering and remediation work in the
         Northwest and Alaska under the Comprehensive Long-Term Environmental
         Action-Navy ("Navy CLEAN") program and two contracts with the U.S.
         Environmental Protection Agency ("EPA") under its Alternative Remedial
         Contracting Strategy ("EPA ARCS") program.  Under the Navy CLEAN
         contract, URS provides site inspections, site characterizations,
         remediation designs and action plans for contaminated Navy facilities.
         A portion of the Navy CLEAN contract, which is expected to have a
         ten-year term, is awarded each year over the life of the contract.  In
         fiscal 1995 and 1994, URS generated revenues associated with the Navy
         CLEAN contract of $16.6 million and $14.3 million, respectively.
         URS's services under the ten-year EPA ARCS contracts include
         investigating the nature and extent of contamination by hazardous
         materials, performing risk assessments, evaluating the feasibility of
         various options for remedial action and providing management,
         technical, quality assurance and health and safety reviews of
         potentially responsible party submittals.  Work under the EPA ARCS
         contracts is performed on a task order basis.  In fiscal 1995 and
         1994, URS recognized revenues of $20.5 million and $26.7 million,
         respectively, under the EPA ARCS contracts.

                 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.

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.

CLIENTS

         URS's clients include local, state and Federal government agencies and
private sector businesses.  URS's revenues from local, state and Federal
government agencies and private businesses for the last five fiscal years are
as follows:

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 over-estimates 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.

BACKLOG, PROJECT DESIGNATIONS AND INDEFINITE DELIVERY CONTRACTS

         URS's contract backlog was $196,400,000 at October 31, 1995, compared
to $159,100,000 at October 31, 1994.  URS's contract backlog consists of the
amount billable at a particular point in time for future services under





                                      52
<PAGE>   60
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 are actually issued and funded.  Of
the contract backlog of $196,400,000 at October 31, 1995, approximately 30%, or
$59,000,000, is not reasonably expected to be filled within the next fiscal
year ending October 31, 1996.

         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 $194,000,000 at October 31, 1995, as compared to
$172,000,000 at October 31, 1994.  Typically, a significant portion of
designations are converted into signed contracts.  However, there is no
assurance this will continue to occur in the future.

         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.  Examples of such contracts are the Navy CLEAN and EPA ARCS
contracts.  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 is 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 October 31, 1995, the potential value of URS's
five largest indefinite delivery contracts was as follows:

EMPLOYEES

         URS has approximately 1,500 full-time and part-time and temporary
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.  Twenty-seven 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.

ACQUISITIONS

         In January 1995, URS acquired privately-held E.C. Driver & Associates,
Inc. ("ECD") of Tallahassee, Florida.  ECD is a leading Florida-based
transportation engineering firm specializing in bridge and highway design,





                                      53
<PAGE>   61
including particular expertise in moveable bridges.  The 50-person firm has
annualized revenues of approximately $5,000,000.

         On December 3, 1995, URS and Greiner executed a letter of intent for
URS to acquire all the outstanding stock of Greiner pursuant to a merger of
Greiner with a wholly-owned subsidiary of URS.  Greiner is a professional
services firm operating in the engineering and architectural design services
industry and headquartered in Irving, Texas.  The acquisition price will
consist of $13.50 in cash plus 0.298 shares of URS Common Stock for each of the
4,704,642 outstanding shares of Greiner Common Stock, for an aggregate price of
approximately $64,000,000 and 1,400,000 shares of URS Common Stock.  Completion
of this transaction is subject to due diligence, mutual approval of a formal
purchase agreement, and shareholder, regulatory and other approvals.  The
transaction is expected to close by April, 1996.

PROPERTIES

         URS leases office space in 24 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.

LEGAL PROCEEDINGS

         Certain subsidiaries of URS have been named as defendants in legal
proceedings wherein substantial damages are claimed.  Such proceedings are not
uncommon in its business and usually involve claims against multiple defendants
who were involved in the project which is the subject of the proceeding.
Historically, URS subsidiaries have been successful in defending such actions
or have settled them within insured limits.  In the opinion of URS management,
based upon its present knowledge, URS ultimate liability, if any, in these
proceedings is not expected to exceed amounts previously provided for in the
consolidated financial statements.  See "Risk Factors - Legal Proceedings /
Liability Insurance Coverage."

    The authorized capital stock of URS consists of 20,000,000 shares of URS
Common Stock, $.01 par value per share, and 1,000,000 shares of preferred

                        INFORMATION CONCERNING GREINER

OVERVIEW

         Greiner is a professional services firm operating in the engineering
and architectural design services industry.  Greiner, through its operating
subsidiaries, provides a broad range of engineering, planning, architectural,
environmental analysis, design, surveying, program management and other
services to public and private sector clients throughout the United States, its
territories and in foreign countries, including Hong Kong and Malaysia.
Greiner's services have been provided through the following market-focused
divisions of Greiner:

    o    SURFACE TRANSPORTATION -- serving governmental agencies and
         private entities responsible for planning, designing and
         operating and maintaining highways, bridges and rail
         transportation facilities.

    o    AIR TRANSPORTATION -- serving governmental agencies and
         private entities (including air carriers) responsible for
         planning, designing and operating and maintaining airports and
         airport-related facilities.

    o    DEVELOPMENT -- serving private sector owners, developers and
         operators of commercial, industrial and recreational
         properties.

    o    INSTITUTIONAL -- serving public agencies and private entities
         engaged in planning, designing and operating and maintaining
         institutional facilities such as schools and health care
         facilities.

    o    WATER RESOURCES -- serving public agencies and private
         entities engaged in the supply, storage, treatment and control
         of water and wastewater and the provision of other municipal
         services.

    o    MARINE TRANSPORTATION -- serving developers and operators of
         port and marine transportation facilities.

    o    FEDERAL/MILITARY -- serving federal government agencies and
         military branches responsible for planning, designing,
         operating and maintaining government and military facilities.

         Greiner has historically concentrated its professional services in the
transportation infrastructure area (highways, bridges, airports and transit
systems).  Greiner's specialization and expertise in the field of
transportation engineering dates back, through its subsidiary operations, to
the early 1900's.  Among the notable transportation projects in which Greiner
has been involved are the Pennsylvania Turnpike, the Chesapeake Bay Bridges,
the Washington, D.C. Metro rail-transit system and the new Denver and Hong Kong
International Airports.

         Greiner operates throughout the United States and in Hong Kong and
Malaysia through over 40 offices.  Based on total revenue for the year ended
December 31, 1994, Greiner is ranked in the top 50 design services firms  in
America and is one of the top five firms which specialize in transportation
engineering in the United States according to the Engineering News Record (a
McGraw-Hill publication).

         Greiner was incorporated in California in 1954 and reincorporated in
Nevada in 1986.  Greiner's shares are listed on the NYSE and the PSE.

COMPETITION

         The market in which Greiner provides services is highly competitive.
Greiner's competitors include large national firms as well as many small local
firms.  Greiner competes with these firms on the basis of technical
capabilities, qualifications and availability of personnel, experience,
reputation, quality of performance and, to a lesser extent, price of services.

</TABLE>

         The amount of revenue earned by Greiner for services performed outside
of the United States during each of the last three fiscal years was not
significant; however, Greiner has been involved in major projects in Hong Kong
in each of the last three years.  Revenue derived from services to domestic
governmental agencies was approximately 80% of the consolidated revenue for
each of the years 1993 through 1995.  Also, for each of the years 1993 through
1995 Greiner had no single customer from which it derived 10% or more of its
revenue.    Pass-through subconsultant and other direct materials costs were
approximately 26%, 25% and 24% of revenue in 1995, 1994 and 1993, respectively.

         Greiner's backlog is the sum of its Category I and Category II
backlog.  Category I backlog is the estimated revenue, excluding pass-through
subconsultant costs and other direct materials costs, from contracts entered
into with clients less that portion of the contracts which Greiner has already
reported as revenue.  Category II backlog is based upon estimated revenue,
excluding pass-through subconsultant costs and other direct materials costs,
from projects for which Greiner has been selected and is negotiating a contract
or is awaiting receipt of a "Notice to Proceed" on a signed contract.

         Greiner's backlog at December 31, 1995 was approximately $170,000,000
and at December 31, 1994 was approximately $162,000,000.  Management estimates
that approximately $100,000,000 of services included in Greiner's backlog at
December 31, 1995 will be performed in 1996.  Greiner also expects additional
revenue in 1996 from sales generated in 1996 which are not included in the
December 31, 1995 backlog.

         The composition of backlog as of the dates indicated was as follows:

</TABLE>

         Greiner's backlog is subject to revision from time to time due to
cancellations, modifications or changes in the scope of work or changes in
design and construction schedules of particular projects.  While Greiner
management believes that its backlog estimates are accurate, there can be no
assurance that such backlog will be realized.

COMPLIANCE WITH ENVIRONMENTAL LAWS

         Compliance with Federal, state and local regulations which have been
enacted or adopted relating to the protection of the environment is not
expected to have any material effect upon the capital expenditures, earnings
and competitive position of Greiner.  However, such compliance by Greiner's
clients may increase the need for the environmental related services which
Greiner provides.

Grand Rapids, Michigan; Orlando, Florida; Phoenix, Arizona; Santa Ana and
Pleasanton, California; Tampa, Florida; Timonium, Maryland; Rocky Hill,

LEGAL PROCEEDINGS

         Certain subsidiaries of Greiner have been named as defendants in legal
proceedings wherein substantial damages are claimed.  Such proceedings are not
uncommon in its business and usually involve claims against multiple defendants
who were involved in the project which is the subject of the proceeding.
Historically, Greiner's subsidiaries have been successful in defending such

management, based upon its present knowledge, Greiner's ultimate liability, if
any, in these proceedings is not expected to exceed amounts previously provided

Directors received an annual director's fee of $15,000, plus an attendance fee
of $2,000 for each URS Board of Directors meeting attended, and a fee of $500
for participation in any telephonic URS Board of Directors meeting.
Non-employee directors who are members of a committee of the Board received
$625 for each committee meeting attended and the Chairman of the committee
received an additional $625 per meeting.  Employee members of the URS Board of
Directors did not receive any such fees.  In addition, URS maintains a policy
whereby non-employee directors may be hired on an as-needed 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 Stockholders, each
non-employee director who is reelected to serve as a director automatically
receives an option to purchase 1,000 shares under the 1991 Stock Incentive
Plan.  During fiscal year 1995, Messrs. Blum, Cashin, Der Marderosian, Foley,
Madden, Praeger and Walsh each received an option to purchase 1,000 shares
under the 1991 Stock Incentive Plan for services rendered as non-employee
directors during fiscal year 1995.  Employee members of the URS Board of
Directors did not receive any such options.

         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.  RCBA, Inc., in its capacity
as the sole general partner of RCBA, L.P., indirectly through several entities,
holds 2,472,693 shares (assuming the exercise of certain warrants), or
approximately 34 percent, of URS's outstanding Common Stock.  Mr. Blum is the
majority stockholder of RCBA, Inc.

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 ceases to be employed by URS for any reason other than
for cause within one year following a Change in Control (see below), he becomes
entitled to a special severance payment equal to three times 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, 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.

         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 URS 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 URSC, 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.  Change in Control is defined in Mr.
Rosenstein's agreement as the acquisition by any person of 51 percent of more
of URSC's or URS's then current outstanding securities having the right to vote
at elections of Directors.

         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 URS
Common Stock on the same economic basis as the SARs.  The SARs are fully
vested.

         Martin S. Tanzer, Ph.D.  Dr. Tanzer has an evergreen employment
agreement with URSC, executed in August 1991, under which Dr. Tanzer received
an annual base salary of $220,000 from November 1, 1992 through November 14,
1994 and $240,000 from November 15, 1994 through December 17, 1995.  On
December 15, 1995, the Compensation/Option Committee increased Dr. Tanzer's
annual base salary, effective December 18, 1995, to $250,000.  The agreement
also obligates URS to maintain a $400,000 term life insurance policy for Dr.
Tanzer and disability insurance providing him with benefits of at least $7,000
per month in the event of his disability.  If Dr. Tanzer'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 Dr. Tanzer ceases to be employed by URS within one year following a Change
of Control (as defined above in the description of Mr. Rosenstein's employment
agreement), Dr. Tanzer will be entitled to receive a severance payment equal to
200 percent of his then current base salary.

         Under the terms of an earlier employment agreement executed in
February 1989, Dr. Tanzer was granted SARs on 5,000 shares at the base price of
$26.25 which expire upon the earlier of February 27, 1999 or the termination of
Dr.  Tanzer's employment with URS.  At URS's option, Dr. Tanzer's SARs may at
any time be replaced with options to purchase URS Common Stock on the same
economic basis as the SARs.  The SARs are fully vested.

         Kent P. Ainsworth.  Mr. Ainsworth executed an evergreen employment
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.  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 is terminated by URS other
than for cause or voluntarily leaves for specified reasons within one year
following a Change of Control (as defined in the description of Mr. Koffel's
employment agreement), Mr. Ainsworth will be entitled to receive a 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.

            COMPARISON OF RIGHTS OF STOCKHOLDERS OF URS AND GREINER

         URS is incorporated in the state of Delaware and is subject to the
provisions of the Delaware General Corporation Law (the "DGCL").  Greiner is
incorporated in the state of Nevada and is subject to the provisions of the
Nevada General Corporation Law ("NGCL").  Following the consummation of the
Merger, stockholders of Greiner will hold URS Common Stock rather than Greiner
Common Stock and, therefore, the rights of such stockholders will be governed
by the DGCL and URS's Certificate of Incorporation (the "URS Certificate") and
URS's Bylaws.

         There are many similarities between the DGCL and the NGCL, as well as
between the charter and bylaws of URS and Greiner; however, a number of
differences do exist.  The following is a summary comparison of certain
differences affecting stockholder rights in the provisions of the NGCL and the
DGCL and the charter documents and bylaws of URS and Greiner.  This summary
does not purport to be a complete discussion of, and is qualified in its
entirety by reference to, the corporate statutes of Nevada and Delaware, and
the URS Certificate and the URS Bylaws and the Greiner Restated Articles of
Incorporation (the "Greiner Articles") and the Greiner Bylaws.

CUMULATIVE VOTING

         In an election of directors governed by cumulative voting rights, each
share of stock otherwise having one vote is entitled to a number of votes equal
to the number of directors to be elected.  A stockholder may then cast all such
votes for a single nominee or may allocate them among as many nominees as the
stockholder may choose.  Without cumulative voting rights, the holders of a
majority of the shares present at an annual meeting or any special meeting held
to elect directors would have the power to elect all the directors to be
elected at that meeting, and it is possible that no person could be elected
without the support of holders of a majority of the shares voting at such
meeting.

         Under the DGCL and the NGCL, cumulative voting rights in the election
of directors are not mandatory and are not available to stockholders unless
provided for in the corporation's certificate of incorporation.  Neither the
URS Certificate nor the Greiner Articles provide for cumulative voting rights.

STOCKHOLDER POWER TO CALL SPECIAL STOCKHOLDERS MEETINGS

         Under the DGCL and the NGCL, a special meeting of stockholders may be
called by the board of directors or any other person specified in the
certificate of incorporation or bylaws.  Greiner's Bylaws provide that only the
president or chairman of the board may call special meetings.  URS's Bylaws
provide that special meetings of the stockholders, for any purpose or purposes,
may be called by the president, and must be called by the president or the
secretary at the request in writing of a majority of the URS Board of
Directors, or at the request in writing of stockholders owning not less than
20% of the issued and outstanding capital stock of URS entitled to vote.

SIZE OF BOARD OF DIRECTORS

         Under the NGCL and the DGCL, the number of directors may be stated in
the certificate of incorporation or the bylaws, or may be determined in the
manner provided in the bylaws.  Greiner's Bylaws provide that the number of
directors may be not less than three nor more than eleven, and will be
determined from time to time by resolution of the Greiner Board of Directors.
Greiner's Board of Directors currently consists of six members.  URS's Bylaws
provide that the number of directors may be not less than five nor more than
eleven, and will be determined from time to time by resolution of the Greiner
Board of Directors or by the stockholders at the annual meeting.  The URS Board
of Directors currently consists of nine members.

CLASSIFIED BOARD OF DIRECTORS

         The DGCL and the NGCL each provide that a corporation's board of
directors may be divided into various classes with staggered terms of office;
provided that, in the case of the NGCL, at least one-fourth of the directors
must be elected annually.  Classification of directors has the effect of making
it more difficult for stockholders to change the composition of a corporation's
board.  At least two annual meetings of stockholders, instead of one, will





                                      75
<PAGE>   83
generally be required to effect a change in the majority of a corporation's
board.  Such a delay may help ensure that the corporation's directors, if
confronted by a holder attempting to force a proxy contest, a tender or
exchange offer or other extraordinary corporate transaction, would have
sufficient time to review the proposal as well as any available alternatives to
the proposal and to act in what they believe to be the best interests of the
stockholders.

         The classification provisions could also have the effect of
discouraging a third party from initiating a proxy contest, making a tender
offer or otherwise attempting to obtain control of a corporation, even though
such a transaction could be beneficial to the corporation and its stockholders.
The classification of a corporation's board might also increase the likelihood
that incumbent directors will retain their positions.

         None of the Greiner Articles, Greiner Bylaws, URS Certificate or URS
Bylaws currently provide for a classified board.  The adoption of a classified
board would require the vote of the stockholders of Greiner or URS.

REMOVAL OF DIRECTORS

         Under the NGCL, a director may be removed by the vote of the holders
of not less than 66-2/3% of the voting power of the voting stock, subject to
certain restrictions concerning cumulative voting.  However, a Nevada
corporation may include in its articles of incorporation a provision requiring
the approval of a larger percentage of the stockholders to remove a director.
Any vacancy in the board of directors may be filled by a majority of the
remaining directors, though less than a quorum, even if the vacancy is due to
an increase in the number of directors.  The Greiner Bylaws do not permit
cumulative voting, and provide that directors may be removed with or without
cause by the vote of not less than 66-2/3% of the voting power of the voting
stock.

         Under the DGCL, a director of a corporation that does not have a
classified board of directors may be removed with or without cause by
stockholder vote; provided, that in the case of a corporation having cumulative
voting, if less than the entire board is to be removed, a director may not be
removed if the shares voted against such removal would not be sufficient to
elect the director under cumulative voting rules at an election of the Board of
Directors.  A director of a corporation with a classified board of directors
can be removed only for cause unless the certificate of incorporation otherwise
provides.  Since there is no controlling definition of "cause" under Delaware
law, the resolution of any dispute as to what constitutes "cause" may be a
matter for determination by the courts.  The URS Certificate and Bylaws do not
provide for a classified board of directors or for cumulative voting.

VOTING REQUIREMENTS

         The NGCL requires most amendments to the articles of incorporation to
be approved by the board of directors, then by the vote of the holders of a
majority of the voting stock, unless the articles of incorporation require a
greater percentage of votes.  If an amendment would alter any preferences or
relative rights of a class or series of outstanding shares, it must be approved
by a majority of the outstanding shares of each class or series so affected,
regardless of limitations or restrictions on the voting power thereof.  The
NGCL gives the board of directors the power to make bylaws, subject to any
limitations contained in bylaws adopted by the stockholders.  The Greiner
Articles do not contain any provisions requiring a greater percentage of votes
for amendment.  The Greiner Bylaws may be amended by the vote of a majority of
directors at any meeting at which a quorum is present.

         Under the DGCL, a corporation with stock outstanding or subscribed
ordinarily may amend its charter provided that the amendment is advised by the
board of directors and approved by affirmative vote of a majority of all the
votes entitled to be cast.  Holders of a class of stock may vote as a class if
the amendment would increase or decrease the number of authorized shares of
such class or the par value of shares of such class, or would alter the
preferences, powers, or special rights of any class so as to affect them
adversely.  The URS Certificate provides that the corporation reserves the
right to amend, alter, change or repeal any provision in the certificate of
incorporation as prescribed by the DGCL.  As a result, the URS Certificate may
be amended provided that the amendment is advised by the board of directors and
approved by the affirmative vote of a majority of all of the outstanding shares
of URS Common Stock.

BUSINESS COMBINATIONS / REORGANIZATIONS

         Section 203 of the DGCL provides that, subject to certain exceptions
specified therein, a corporation shall not engage in any business combination
with any "interested stockholder" for a three-year period following the date
that such stockholder becomes an interested stockholder unless (i) prior to
such date, the board of directors of the corporation approved either the
business combination or the transaction which resulted in the stockholder
becoming an interested stockholder, (ii) upon consummation of the transaction
which resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced (excluding shares
held by directors who are also officers and employee stock purchase plans in
which employee participants do not have the right to determine confidentially
whether plan shares will be tendered in a tender or exchange offer) or (iii) on
or subsequent to such date, the business combination is approved by the board
of directors of the corporation and by the affirmative vote at an annual or
special meeting, and not by written consent, of at least 66-2/3% of the
outstanding voting stock which is not owned by the interested stockholder.

         Except as specified in Section 203 of the DGCL, an interested
stockholder is defined to include (a) any person that is the owner of 15% or
more of the outstanding voting stock of the corporation or is an affiliate or
associate of the corporation and was the owner of 15% or more of the
outstanding voting stock of the corporation, at any time within three years
immediately prior to the relevant date and (b) the affiliates and associates of
any such person.

         For purposes of Section 203, the term "business combination" is
defined broadly to include mergers with or caused by the interested
stockholder; sales or other dispositions to the interested stockholder (except
proportionately with the corporation's other stockholders) of assets of the
corporation or a subsidiary equal to ten percent or more of the aggregate
market value of the corporation's consolidated assets or its outstanding stock;
the issuance or transfer by the corporation or a subsidiary of stock of the
corporation or such subsidiary to the interested stockholder (except for
transfers in a conversion or exchange or a pro rata distribution or  certain
other transactions, none of which increase the interested stockholder's
proportionate ownership of any class or series of the corporation's or such
subsidiary's stock); or receipt by the interested stockholder (except
proportionately as a stockholder), directly or indirectly, of any loans,
advances, guarantees, pledges or other financial benefits provided by or
through the corporation or a subsidiary.

         The three-year moratorium imposed on business combinations by Section
203 does not apply if:  (a) prior to the date on which such stockholder becomes
an interested stockholder the board of directors approves either the business
combination or the transaction which resulted in the person becoming an
interested stockholder; (b) the interested stockholder owns 85% of the
corporation's voting stock upon consummation of the transaction which made him
an interested stockholder (excluding from the 85% calculation shares owned by
directors who are also officers of the target corporation and shares held by
employee stock plans which do not permit employees to decide confidentially
whether to accept a tender or exchange offer); or (c) on or after the date such
person becomes an interested stockholder, the board approves the business
combination and it is also approved at a stockholder meeting by sixty-six and
two-thirds percent (66-2/3%) of the voting stock not owned by the interested
stockholder.

         Section 203 only applies to Delaware corporations which have a class
of voting stock that is listed on a national securities exchange, are quoted on
an interdealer quotation system such as the New York Stock Exchange (as is URS)
or are held of record by more than 2,000 stockholders.  A Delaware corporation
may subsequently elect not to be governed by Section 203 by an amendment to its
charter or to the bylaws, which amendment must be approved by majority
stockholder vote.

         Under certain circumstances, Section 203 of the DGCL may make it more
difficult for a person who would be an "interested stockholder" to effect
various business combinations with a corporation for a three-year period,
although the corporation's certificate of incorporation or stockholders may
elect to exclude a corporation from the restrictions imposed thereunder.  The
URS Certificate does not exclude URS from the restrictions imposed under
Section 203 of the DGCL.  It is anticipated that the provisions of Section 203
of the DGCL may encourage companies interested in acquiring URS to negotiate in
advance with URS, since the stockholder approval





                                      77
<PAGE>   85
requirement would be avoided if a majority of the directors then in office
approve either the business combination or the transaction which results in the
stockholder becoming an interested stockholder.

         Section 203 has been challenged in lawsuits arising out of ongoing
takeover disputes, and it is not yet clear whether and to what extent its
constitutionality will be upheld by the courts.  Although the United States
District Court for the District of Delaware has consistently upheld the
constitutionality of Section 203, the Delaware Supreme Court has not yet
considered the issue.  URS believes that so long as the constitutionality of
Section 203 is upheld, Section 203 will encourage any potential acquiror to
negotiate with URS's Board of Directors.  Section 203 also has the effect of
limiting the ability of a potential acquiror to make a two-tiered bid for URS
in which all stockholders would not be treated equally.  Section 203 may also
discourage certain potential acquirors unwilling to comply with its provisions.

         The NGCL also prohibits certain business combinations between a
corporation and an "interested stockholder" (one beneficially holding, directly
or indirectly, at least 10% of the outstanding voting stock) for five years
after such person became an interested stockholder unless such interested
stockholder, prior to becoming an interested stockholder, obtained the approval
of the board of directors of either the business combination or the transaction
that resulted in such person becoming an interested stockholder.
Notwithstanding the foregoing, the NGCL permits business combinations that meet
all requirements of the corporation's articles of incorporation and (i) are
approved by the board of directors before the interested stockholder became an
interested stockholder (or as to which the purchase of shares made by the
interested stockholder had been approved by the board of directors before the
date of purchase), (ii) are approved by the affirmative vote of the holders of
stock representing a majority of the voting stock (excluding voting stock of
the interested stockholder and its affiliates and associates) at a meeting
called for such purpose no earlier than five years after the interested
stockholder became an interested stockholder, or (iii) the form and amount of
consideration to be received by stockholders (excluding the interested
stockholder) of the corporation satisfy certain tests and, with limited
exceptions, the interested stockholder has not become the beneficial owner of
additional voting shares of the corporation after becoming an interested
stockholder and before the business combination is consummated.  A corporation
may expressly exclude itself from application of the foregoing business
combination provisions of the NGCL but Greiner has not done so.

RIGHTS OF DISSENTING STOCKHOLDERS

         Under the NGCL, dissenter's rights do not exist in a merger if the
holder's shares are listed on a national securities exchange, unless the
consideration to be received in the merger is anything but cash and/or stock.
Under the DGCL, dissenters' rights are not available with respect to (a) a sale
of assets, (b) a merger by a corporation, if the shares of the corporation are
either listed on a national securities exchange or held by more than 2,000
stockholders of record or if stockholders receive shares of the surviving
corporation or of a listed or widely-held corporation, or (c) a merger in which
the corporation is the surviving corporation; provided, that no vote of its
stockholders is required to approve the merger.  Because Greiner Common Stock
is listed on the NYSE and because Greiner stockholders will receive cash and
stock in the Merger, stockholders of Greiner will not be entitled to appraisal
rights with respect to the proposed Merger.

INSPECTION OF BOOKS AND RECORDS

         The NGCL provides for an absolute right of inspection of a
corporation's books and records for persons holding 15% or more of the
corporation's voting shares.  The DGCL, however, gives any stockholder of
record the right to inspect a corporation's books and records for a purpose
reasonably related to such person's interest as a stockholder.

DIVIDENDS

         The NGCL permits the payment of dividends, if authorized by the Board
of Directors, however, dividends may not be paid if, after giving it effect,
the corporation would not be able to pay its debts as they become due or the
corporation's assets would be less than the corporation's total liabilities
plus whatever amount would be needed to satisfy preferential rights under
dissolution.

         The DGCL also permits the payment of dividends out of surplus or, if
there is no surplus, out of net profits for the current and preceding fiscal
years (provided that the amount of capital of the corporation is not less than
the





                                      78
<PAGE>   86
aggregate amount of the capital represented by the issued and outstanding stock
of all classes having a preference upon the distribution of assets).  In
addition, Delaware law generally provides that a corporation may redeem or
repurchase its own shares only if such redemption or repurchase would not
"impair the capital" of the corporation.  The ability of a Delaware corporation
to pay dividends on, or redeem or to make repurchases or redemptions of, its
shares is dependent on the financial status of the corporation standing alone
and not on a consolidated basis.  In determining the amount of surplus of a
Delaware corporation, the assets of the corporation, including stock of
subsidiaries owned by the corporation, must be valued at their fair market
value as determined by the board of directors, without regard to their
historical value.

         The Greiner Bylaws provide that dividends may be paid at the
discretion of the Greiner Board.  Greiner has paid dividends since 1988.  URS
has not paid cash dividends since 1986.  See "Summary - Dividend Policy."

LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS

         Both the NGCL and the DGCL permit a corporation to include a provision
in its articles or certificate of incorporation eliminating or limiting the
personal liability of a director or officer to the corporation or its
stockholders for damages for breach of the director's fiduciary duty, subject
to certain limitations.  Each of the Greiner Articles and the URS Certificate
include such a provision, to the maximum extent permitted by law.

         The Greiner Articles provide that a director will not be personally
liable to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability (i) for acts or omissions
which involve intentional misconduct, fraud or a knowing violation of the law
or (ii) the payment of dividends in violation of Section 78.300 of the NGCL.

         Article XI of the URS Certificate provides that a director of the
corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any beach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the DGCL, as the same exists or hereafter may be amended,
or (iv) for any transaction from which the director derived an improper
personal benefit.  Article XI of the URS Certificate further provides that if
the DGCL is amended to authorize the further elimination or limitation of the
liability of directors, then the liability of a director of the corporation, in
addition to the limitation on personal liability provided in Article XI as
currently written, shall be limited to the fullest extent permitted by the
amended DGCL.  Finally, Article XI provides that any repeal or modification of
Article XI shall be prospective only, and shall not adversely affect any
limitation on the personal liability of a director of the corporation existing
at the time of such repeal or modification.

         While these provisions provide directors with protection from awards
for monetary damages for breaches of their duty of care, they do not eliminate
such duty.  Accordingly, these provisions will have no effect on the
availability of equitable remedies such as an injunction or rescission based on
a director's breach of his or her duty of care.  The provisions described above
apply to an officer of the corporation only if he or she is a director of the
corporation and is acting in his or her capacity as director, and do not apply
to officers of the corporation who are not directors.

         In addition, both the NGCL and the DGCL permit a corporation to
indemnify officers, directors, employees and agents for actions taken in good
faith and in a manner they reasonably believed to be in, or not opposed to, the
best interests of the corporation, and with respect to any criminal action,
which they had no reasonable cause to believe was unlawful.  Both states' laws
provide that a corporation may advance expenses of defense (upon receipt of a
written undertaking to reimburse the corporation if indemnification is not
appropriate) and must reimburse a successful defendant for expenses, including
attorney's fees, actually and reasonably incurred, and both states permit a
corporation to purchase and maintain liability insurance for its directors and
officers.  Both the NGCL and the DGCL provide that indemnification may not be
made for any claim, issue or matter as to which a person has been adjudged by a
court of competent jurisdiction, after exhaustion of all appeals therefrom, to
be liable to the corporation, unless and only to the extent a court determines
that the person is entitled to indemnity for such expenses as the court deems
proper.





                                      79
<PAGE>   87
         The Greiner Articles provide that each person who is involved in any
actual or threatened action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he or she is or was
a director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise will be indemnified by the corporation if such person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of Greiner, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.  The
indemnification rights conferred by the Greiner Articles are not exclusive of
any other right to which a person seeking indemnification may be entitled under
any law, bylaw, agreement, vote of stockholders or disinterested directors or
otherwise.

         The URS Bylaws provide that any officer, director or employee of URS
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, wither civil, criminal,
administrative or investigative (other than an action by or in the right of the
corporation), by reason of the fact that he or she is or was a director,
officer or employee of the corporation, or is or was serving at the request of
the corporation as a director, officer or employee of another corporation or of
a partnership, joint venture, trust or other enterprise, shall be indemnified
by the corporation if such person acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that his or her conduct was unlawful.  In addition,
the URS Bylaws provide that any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action or suit by or
in the right of the corporation to procure a judgment in its favor by reason of
the fact that he or she is or was a director, officer or employee of the
corporation, or is or was serving at the request of the corporation as a
director, officer or employee of another corporation, partnership, joint
venture, trust or other enterprise, shall be indemnified by the corporation if
such person acted in good faith any in a manner he or she reasonably believed
to be in, or not opposed to, the best interests of the corporation; provided,
however, that no indemnification shall be made in respect of any claim, issue
or manner as to which such person shall have been adjudged to have been liable
for negligence or misconduct in the performance of his or her duties to the
corporation (unless a court shall determine, upon application, that such person
is reasonably entitled to indemnity for such expenses which the court deems
proper).  The indemnification rights conferred by the URS Bylaws are not
exclusive of any other right to which a person seeking indemnification may be
entitled under any law, bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers or controlling
the registrant pursuant to the foregoing provisions, the registrant has been
informed that in the opinion of the SEC such indemnification is against public
policy as expressed in the Act and is therefore unenforceable.

              AFFILIATES' RESTRICTION ON SALE OF URS COMMON STOCK

    The shares of URS Common Stock to be issued pursuant to the Merger have
been registered under the Securities Act by a Registration Statement on Form
S-4, thereby allowing such securities to be traded without restriction by any
former holder of Greiner Common Stock who is not deemed to be an "affiliate" of
Greiner prior to the consummation of the Merger, as "affiliate" is defined for
purposes of Rule 145 under the Securities Act, and who does not become an
"affiliate" of URS after the consummation of the Merger.

    Shares of URS Common Stock received by persons who are deemed to be
affiliates of Greiner prior to the Merger may be resold by them only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act or as otherwise permitted under the Securities Act.  Rule
145, as currently in effect, imposes restrictions in the manner in which such
affiliates, and others with whom they might act in concert, may sell URS Common
Stock within any three-month period.  Persons who may be deemed to be
affiliates of Greiner generally include individuals or entities that control,
are controlled by or are under common control with Greiner and may include
certain officers and directors as well as principal stockholders of Greiner.
Greiner stockholders who are identified as affiliates will be so advised by
Greiner prior to the Effective Date.

    Each of URS and Greiner will use its best efforts to cause each and any
Greiner stockholder who is an affiliate to agree not to make any public sale of
any URS Common Stock received upon consummation of the Merger except in
compliance with Rule 145 under the Securities Act or otherwise in compliance
with the Securities Act.  In general, Rule 145, as currently in effect, imposes
restrictions on the manner in which such affiliates may make resales of URS
Common Stock and also on the quantity of resales that such stockholders, and
others with whom they may act in concert, may make within any three-month
period for a period of two (2) years after consummation of the Merger.  In
addition, officers and directors of URS following the Merger will be subject to
the resale restrictions of Rule 144 as it applies to affiliates of an issuer.

                       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, 1995 and 1994, 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,
1995.  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, 1995 and 1994, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended October 31, 1995, in conformity with generally
accepted accounting principles.

         As discussed in the notes to the consolidated financial statements,
effective November 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes.

                       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 and
its subsidiaries, all of which are wholly-owned.  All significant intercompany
accounts and transactions have been eliminated in consolidation.

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
URS for additional contract compensation is recorded when agreed to by the
customer.  If estimated total costs on any contract indicate a loss, URS
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 1995
are subject to review by the U.S. Government.

Cash and Cash Equivalents

         URS considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.  Cash equivalents are recorded
at cost, which approximates fair value.

Income Taxes

         Effective November 1, 1993, URS adopted the provisions of Statement of
Financial Accounting Standards ("SFAS") Number 109, "Accounting for Income
Taxes."  This standard requires companies to record all deferred tax
liabilities and assets for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax basis, including tax loss
carryforwards.  As permitted under SFAS Number 109, prior years' financial
statements were not restated.  This did not materially affect URS's
consolidated financial statements.

Depreciation and Amortization

         Depreciation is provided on the straight-line method over the useful
service lives of the assets.  Goodwill is amortized on the straight-line method
ranging from 10 to 20 years.

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 URS'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.

NOTE 2.   QUASI-REORGANIZATION

         In conjunction with a restructuring completed in fiscal year 1990,
URS, 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 URS'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 $92,523,000 was
eliminated against additional paid-in capital.  The balance in retained
earnings at October 31, 1995 represents the accumulated net earnings arising
subsequent to the date of the quasi-reorganization.

NOTE 3.   ACQUISITION

         During the year ended October 31, 1995, URS acquired E.C. Driver &
Associates, Inc. ("ECD") for an aggregate purchase price of $3,596,000, and the
assumption of ECD's liabilities totaling $1,356,000.  This acquisition was
accounted for by the purchase method of accounting and the net assets of ECD
are included in URS's consolidated balance sheet as of October 31, 1995 based
upon its 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 URS's reported
results.  The excess of the purchase price over the estimated fair value of the
assets acquired (goodwill) of $3,596,000 will be amortized on a straight line
basis over twenty years.

         As of October 31, 1995, URS has available net operating loss ("NOL")
carryforwards for Federal income tax purposes and financial statement purposes
of $6,750,000.  The NOL utilization is limited to $750,000 per year.

         While URS has available NOL carryforwards which partially off-set
otherwise taxable income for Federal income tax purposes, for state tax
purposes such amounts are not necessarily available to offset income subject to
tax.  Accordingly, state income taxes have been provided.

Credit Agreement

         At October 31, 1995, URS's unsecured line of credit agreement with
Wells Fargo Bank, National Association ("the "Bank") provides for advances up
to $15,000,000 and expires April 30, 1997.  Borrowings on the line of credit
bear interest at the option of URS at a per annum rate equal to either the
Bank's prime rate, or 1.5% over the interest rate offered to the Bank in the
interbank Eurodollar market, adjusted for the Bank's Eurodollar reserve
requirements.  At October 31, 1995, URS had outstanding letters of credit
totaling $386,000 which reduced the amount available to URS under its unsecured
line of credit to $14,614,000.

         To finance the cash portion of the proposed Greiner acquisition
(discussed more fully in Note 16 - "Subsequent Event"), URS is negotiating to
obtain a $20,000,000 senior secured revolving credit facility expiring three
years from the closing of the loan and a $50,000,000 senior secured term loan
maturing six years from the closing of the loan.  The senior secured revolving
credit facility would replace the current unsecured line of credit.

         Under the unsecured line of credit agreement URS is required to
satisfy certain financial and non-financial covenants.  The declaration of
dividends, except stock dividends, is restricted by the terms of URS's
unsecured credit agreement with the Bank and the indenture governing the 8 5/8%
Senior Subordinated Debentures due 2004 (the "8 5/8 Indenture"), described
below.  URS was in compliance with all financial and non-financial covenants
related to the unsecured line of credit agreement at October 31, 1995 and to a
predecessor secured line of credit agreement at October 31, 1994.

Related Parties

         At October 31, 1995, URS had fully-drawn $4,000,000 under its line of
credit with Richard C. Blum & Associates, L.P. ("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 22% of
URS's Common Stock (approximately 34% assuming exercise


                                     F-13
<PAGE>   103
of additional warrants) outstanding at October 31, 1995.  Richard C. Blum, a
director of URS, is also Chairman of RCBA.

Debentures

         URS's 6 1/2% Convertible Subordinated Debentures due 2012 are
convertible into URS'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 URS's 8 5/8%
Senior Subordinated Debentures due 2004.  Both the 6 1/2% Convertible
Subordinated Debentures and the 8 5/8% Senior Subordinated Debentures are
subordinate to all debt to RCBA and the Bank.

         The amounts of long-term debt outstanding at October 31, 1995 maturing
in the next five years are as follows:

Obligations under Leases

         Total rental expense included in operations for operating leases for
the fiscal years ended October 31, 1995, 1994 and 1993 amounted to $5,717,000,
$5,275,000 and $4,938,000, respectively. Certain of the lease rentals are
subject to renewal options and escalation based upon property taxes and
operating expenses.  These operating lease agreements expire at varying dates

NOTE 8.   COMMITMENTS AND CONTINGENCIES

         Currently, URS has $31,000,000 per occurrence and aggregate commercial
general liability insurance coverage.  URS is also insured for professional
errors and omissions ("E&O") and pollution liability ("EIL") claims with an
aggregate limit of $25,000,000 after a self-insured deductible of $500,000.
The E&O and EIL 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.

         Various legal proceedings are pending against URS 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 URS's insurance coverage.  URS's management
does not believe that any of such proceedings will have a material adverse
effect on the consolidated financial position and operations of URS.

NOTE 9.   CAPITAL STOCK

         Declaration of dividends, except Common Stock dividends, is restricted
by the unsecured line of credit agreement and the 8 5/8% Debenture.  Further,
declaration of dividends may be precluded by existing Delaware law.

         During fiscal year 1995, URS 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 URS's Board of Directors on September
13, 1994.

         The 1987 Restricted Stock Plan (the "Plan") provides for grants of up
to 16,537 shares of Common Stock to key employees of URS 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, 1995, 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 URS 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 URS 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


                                     F-15
<PAGE>   105
key employees of URS 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 1995, URS 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.  The ESP Plan was suspended
effective September 19, 1988.  On March 24, 1992, the stockholders approved
reinstating the ESP Plan.  Employees purchased 46,610 shares under the ESP Plan
in fiscal 1995 and 36,195 shares in fiscal 1994.

         On February 21, 1990, URS 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.

NOTE 13.   RELATED PARTY TRANSACTIONS

         Interest paid to related parties in connection with the January Notes
was $194,000, $363,000 and $254,000 in fiscal 1995, 1994 and 1993,
respectively.  (See Note 7 - Long-Term Debt).

         URS has agreements for business consulting services to be provided by
RCBA and Richard C. Blum, a Director of URS.  Under these agreements, URS paid
$90,000 and $60,000 to RCBA and Richard C. Blum, respectively, for fiscal 1995,
1994 and 1993.  Richard C. Blum also received an additional $25,000, $24,000
and $19,000 for his services as a Director of URS in fiscal 1995, 1994 and
1993, respectively.  In addition, during fiscal 1993, URS Consultants, Inc., a
wholly- owned subsidiary of URS ("URSC"), performed an underground storage tank
remediation investigation on behalf of RCBA.  Such investigation was completed
by October 28, 1993, and on November 19, 1993, RCBA, Inc. paid URSC $70,000 in
gross revenues.

NOTE 14.   CONCENTRATION OF CREDIT RISK

         URS provides services primarily to local, state and Federal government
agencies.  URS believes the credit risk associated with these types of revenues
is minimal.  However, URS does perform ongoing credit evaluations of its
customers and, generally, requires no collateral.  URS maintains reserves for
potential credit losses and such losses have been within management's
expectations.

NOTE 16.   SUBSEQUENT EVENT

         Subsequent to URS's year-end, a letter of intent was signed to acquire
Greiner Engineering, Inc. for a combination cash and stock transaction
aggregating $63.4 million in cash, and 1.4 million shares of URS's Common
Stock.  Completion of this transaction is subject to a number of conditions
including a satisfactory due diligence review, mutual approval of a formal
purchase agreement, and shareholder, regulatory and other approvals.  The
completion of this transaction is anticipated by April, 1996.  The completion
of the cash portion of this acquisition will necessitate financing via a
revolving credit facility and senior secured term loan, increasing URS's debt
and interest expense.  URS is negotiating a banking agreement which secures
adequate and appropriate financing for this acquisition as well as other future
growth opportunities.

Board of Directors and Stockholders
Greiner Engineering, Inc.
Irving, Texas




In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Greiner
Engineering, Inc. and its subsidiaries at December 31, 1995 and 1994, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1995, in conformity with generally accepted
accounting principles.  These financial statements are the responsibility of
Greiner's management; our responsibility is to express an opinion on these
financial statements based on our audits.  We conducted our audits of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation.  We believe that our audits provide a
reasonable basis for the opinion expressed above.

NOTE 1 - BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business:

Greiner, through its subsidiaries, operates a single line of business which
provides a broad range of engineering, planning, architectural, environmental
analysis, design, surveying, program management and other services to public
and private sector clients throughout the United States, its territories and in
foreign countries, including Hong Kong and Malaysia.  Revenue derived from
services to domestic governmental agencies was approximately 80% of the
consolidated revenue for 1993 through 1995.  Greiner did not derive more than
10% of its consolidated revenue from any one client in any of the years 1993
through 1995.

Principles of Consolidation:

The consolidated financial statements include the accounts of the Company and
its subsidiaries, all of which are wholly owned.  All material intercompany
transactions and balances have been eliminated.

Use of Estimates in the Preparation of Financial Statements:

The preparation of 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 date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Method of Accounting for Contracts:

Greiner records income on its contracts on the percentage-of-completion method.
Revenue is recorded as costs are incurred, and profit is recognized on each
contract based on the percentage that incurred costs bear to estimated total
costs.  In the event of an anticipated loss, the entire amount of the loss is
charged to current operations.

Revenue and the direct cost of revenue include amounts applicable to
subconsultants and other direct material costs on contracts for which Greiner
is responsible.

Depreciation and Amortization:

Greiner depreciates and amortizes property and equipment, which are stated at
cost, on the straight-line method over the following useful lives:

<TABLE>
     <S>                                 <C>
     Buildings                           16-30 years
     Leasehold improvements              10 years or term of lease, whichever is less
     Office furnishings and fixtures     5-7 years
     Equipment                           3-5 years
</TABLE>

Cash Equivalents:

Greiner considers all short-term investments, including U.S. Treasury
repurchase agreements, U.S. Treasury Bills, certificates of deposit and/or
commercial paper with original maturities of 90 days or less to be cash
equivalents.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993

Short-term Investments:

Greiner includes in short-term investments all U.S. Treasury repurchase
agreements, U.S. Treasury Bills, certificates of deposit and/or commercial
paper with original maturities greater than 90 days but less than one year.
The carrying values of these investments are approximately equal to their fair
market value at the end of each year.

Excess of Costs Over Net Assets Acquired:

The excess of costs over net assets acquired of $691,000 at December 31, 1995,
is net of accumulated amortization of $3,204,000.  In 1994, the balance of
$2,359,000 is net of accumulated amortization of $1,536,000.  The amounts are
being amortized on a straight-line basis over a 20-year period.  During the
third quarter of 1995, Greiner incurred restructuring charges which included
additional amortization of $1,500,000 to reduce the carrying value of goodwill
related to the 1990 acquisition of Bissell and Karn, Inc.

Other Assets:

Other assets are composed primarily of investments in real property of $442,000
and $411,000 in 1995 and 1994, respectively.

Investment in Partnerships:

Greiner accounts for its investment in non-majority owned partnerships using
the equity method of accounting.  It is Greiner's policy to periodically review
the underlying assets and expected future revenues of these partnerships and
adjust the carrying value in accordance with such review.

Long-Term Investments:

Greiner had long-term investments of $2,993,000 and $973,000 invested in U.S.
Treasury Notes at December 31, 1995 and 1994, respectively, with maturity dates
in excess of one year.

Earnings (Loss) and Cash Dividends Per Share Information:

Earnings (loss) per share information is based on the weighted average number
of shares of Common Stock outstanding during each period, adjusted for stock
options that have a materially dilutive effect on the calculations of earnings
per share.  Earnings per share are computed independently for each of the
quarters.  As a result, the sum of the quarterly earnings per share may not
equal the earnings per share for the year-to-date results.

Annual cash dividends of $.30, $.28 and $.24 per share of Common Stock were
declared in 1995, 1994 and 1993, respectively, on the historical shares
outstanding at the time of the dividend record dates.

Reclassifications:

Certain reclassifications have been made to the 1994 and 1993 financial
statements to conform to the 1995 presentation.

                                1994 AND 1993

Newly Issued Accounting Standards:

In 1995, Statement of Financial Accounting Standards No. 121, "Accounting for
Long-Lived Assets" (SFAS 121) was issued.  Greiner will adopt this standard in
1996.  The effect of the adoption is not expected to be significant.  In
October 1995, Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-based Compensation" ("SFAS 123"), was issued.  This statement
requires the fair value of stock options and other stock-based compensation
issued to employees to either be included as compensation expense in the income
statement, or the pro forma effect on net income and earnings per share of such
compensation expense to be disclosed in the footnotes to Greiner's financial
statements commencing in 1996.  Greiner expects to adopt SFAS 123 on a
disclosure basis only.  As such, implementation of SFAS 123 is not expected to
impact Greiner's consolidated balance sheet or income statement.

Unbilled accounts receivable principally represent revenue earned during the
latter part of the year but not billed until the following year.  Included in
billed accounts receivable are retainages of approximately $2,800,000 at
December 31, 1995 and $2,700,000 at December 31, 1994, which Greiner expects to
collect within one year.

NTA currently holds the franchise for the tollway extension to State Route 57
("SR 57") in Orange County, California.  To date, NTA has been unsuccessful in
securing necessary financing for the preliminary environmental phases of the SR
57 project and currently holds no other significant project franchises.
Although NTA is continuing to pursue financing alternatives for the SR 57
project and is actively seeking new project opportunities in public/private
transportation projects, the lack of progress on the SR 57 project caused
Greiner to record a non-cash charge of $500,000 in the fourth quarter of 1994
and $2,300,000 in the third quarter of 1995 to reduce the carrying value of its
investment in NTA.

Greiner has an unsecured bank line of credit with an aggregate limit of
$15,000,000 bearing interest at the lower of the bank's prime rate (8 1/2% at
December 31, 1995) or 1 1/2% over the bank's cost of funds rate (5%-5 3/4% at
December 31, 1995 depending on the length of the loan).  Under the terms of the
line of credit, maintenance of specified amounts of net worth and ratios of
working capital are required and payments of cash dividends are restricted to
an amount not in excess of Greiner's current year's earnings.  Greiner exceeded
these dividend restrictions in 1995, however, the bank waived those
restrictions for 1995.  At December 31, 1995 and 1994, no borrowings were
outstanding on the line of credit.

Also included in long-term liabilities are other deferred credits of $1,297,000
(1995) and $1,231,000 (1994) consisting primarily of liabilities associated
with deferred compensation plans discussed in Note 8.

NOTE 8 - COMMITMENTS AND CONTINGENCIES

Rental Commitments:

Future minimum rental commitments under noncancellable operating leases,
principally on buildings and office space, with an initial or remaining term of
more than one year approximated $17,354,000 at December 31, 1995, payable as
follows: $6,356,000 (1996); $4,972,000 (1997);  $2,463,000 (1998);
$1,913,000(1999), $1,009,000 (2000) and $641,000 thereafter.  Certain leases
provide options for renewal at the end of the lease, provide for the payment of
real estate taxes, utilities and insurance and have rent or operating cost
escalation provisions (see Note 10).

Rental expense was $10,800,000 (1995), $8,543,000 (1994) and $8,194,000 (1993).
The amounts of noncancellable subleases, which are not material, have been
deducted from rental expense.

Greiner leases approximately 30,000 square feet of office space in Pleasanton,
California from a partnership of which certain partners were employees of
Greiner.  Total payments by Greiner under this lease agreement were
approximately $628,000 in 1995, $613,000 in 1994 and $610,000 in 1993.

Contingencies:

Certain subsidiaries of Greiner have been named as defendants in legal
proceedings wherein substantial damages are claimed.  Such proceedings are not
uncommon in Greiner's business and usually involve claims against multiple
defendants who were involved in the project which is the subject of the
proceeding.  Historically, Greiner's subsidiaries have been successful in
defending such actions or have settled them within insured limits.  In the
opinion of management, based upon its present knowledge, Greiner's ultimate
liability, if any, in these proceedings is not expected to exceed amounts
previously provided for in Greiner's consolidated financial statements.
Because of the nature of the professional services provided by Greiner and the
size and nature of many of the projects upon which such services are performed,
the potential for claims in excess of insurance limits always exists.  Should
that occur, and if Greiner's resulting liability is material, then Greiner's
operations and financial condition would be adversely affected.  It is also
possible that a large number of claims in any given year could cause the total
amount paid with respect to the deductible amounts relating to such claims to
be material, in which event Greiner's operations and financial condition could
be adversely affected.

In 1995, Greiner was notified by the staff of the Central Regional Office of
the Securities and Exchange Commission (the "Staff") that it planned to
recommend that a subsidiary of Greiner be named as a respondent in an
administrative action relating to the issuance of certain revenue bonds used to
finance the construction of the new Denver International Airport.  The
subsidiary was a member of a joint venture formed for the sole purpose of
acting as the program management consultant for the City and County of Denver
on the new Denver International Airport project.  The joint venture was
dissolved at the completion of the project.  The Staff recommendation relates
to certain information about the airport project provided by the subsidiary to
the City and County of Denver in connection with the related bond offering.
Greiner has disputed the Staff's recommendations.  Management does not
anticipate that the resolution of this matter will have a material effect on
Greiner's operations or financial condition.

                                1994 AND 1993

Greiner presently carries professional liability insurance against claims
resulting from Greiner's alleged negligent performance of professional
services, with an aggregate limit of $30,000,000 per year in excess of an
aggregate $1,000,000 annual self-insured retention and a deductible of $250,000
per occurrence.  This insurance, consistent with industry practice, is on a
"claims made" basis, which means coverage must be in place when a claim is
made. In addition, such insurance is subject to standard exclusions, including
exclusions for claims arising out of actual, alleged or threatened discharge,
dispersal, seepage, migration, release or escape of pollutants and the
performance of or failure to perform professional services rendered in the
abatement, replacement or removal of any product, material or process
containing asbestos.  The continued availability and cost of professional
liability insurance will depend upon market conditions, the claims record of
Greiner and the claims experience of the insurers providing such coverage.

Greiner performs services for certain government entities which are subject to
post contract audit adjustments for periods beyond the project completion date.
In the opinion of management, based upon its present knowledge, Greiner's
ultimate liability, if any, related to these contract audits is not expected to
exceed amounts previously provided for in Greiner's financial statements.

Deferred Compensation Plans:

Greiner has deferred compensation plans covering certain of its former senior
executives, which provide for periodic payments upon retirement.  Charges to
operations under these plans were $186,000 (1995), $193,000 (1994) and $189,000
(1993).

Employee Incentive Programs:

Greiner has adopted a profit sharing formula for determining its contribution
to the Performance Plan and Employee Stock Ownership Plan of Greiner
Engineering, Inc. (the "Performance Plan") and for management cash incentive
payments.  The profit sharing formula is based on a sliding scale of Company
profits.  A minimum level of profit equal to six percent of net revenue before
taxes and incentives is necessary to generate a contribution pool for these
plans.  The maximum contribution to these plans is 33% of Greiner's profit
before computation of taxes and contributions to these incentive plans.  Total
charges to operations under the profit sharing formula amounted to $0 (1995),
$1,681,000 (1994) and $2,770,000 (1993).

The total number of allocated shares held in the ESOP were 612,459, 552,477 and
494,384 at December 31, 1995, 1994 and 1993, respectively.

Employees who have attained the age of twenty-one years and completed six
months of employment are eligible to participate in the Performance Plan.  The
Performance Plan, which is qualified under section 401(k) of the Internal
Revenue Code, includes an employee stock ownership provision, pursuant to which
all Company contributions to the Performance Plan have been used to purchase
shares of Greiner's Common Stock.

If the proposed merger discussed in Note 11 is consummated, the ESOP would be
terminated and all shares will be converted into other investment options in
the Performance Plan designated by the participants.

NOTE 10 - RESTRUCTURING CHARGES

During 1995, Greiner initiated various activities to restructure certain of its
operations in order to reduce its cost structure and improve profitability.

Greiner shifted its center of Asian operations from Hong Kong to Kuala Lumpur,
Malaysia.  Through consolidation of the Asian activities in its Kuala Lumpur
office, Greiner will be able to reduce its office staff and office space in
Hong Kong.  Greiner recorded a 1995 restructuring charge of $500,000 for this
office shift, primarily related to the termination of lease obligations.

Greiner has historically maintained two principal service disciplines in the
California marketplace - land development design and surface transportation
design.  Continuing hardships in California's residential land development
market have prompted Greiner's decision to de-emphasize residential land
development services within that geography.  The firm intends to continue to
pursue transportation infrastructure projects and serve commercial,
recreational and industrial clients.  In redirecting its market priorities, the
firm will complete existing contract obligations to residential developers and
then reduce staff and office space and consolidate office locations to match
its ongoing level of operations.

Restructuring charges associated with the closing of these offices and the
early termination or sublease of the office leases of $1,375,000 were recorded
in 1995.  An additional $85,000 was accrued in 1995 to cover the office
closeout costs.  Approximately 30 employees in Greiner's land development group
will be terminated in 1996. Costs related to these staff reductions of $240,000
were accrued in 1995.

A significant portion of Greiner's residential land development business was
obtained through the 1990 acquisition of Bissell and Karn, Inc.  As a result of
the restructuring of the California operations, Greiner recorded a non-cash
charge of $1,500,000 in 1995 to reduce the carrying value of the goodwill
associated with the acquired residential land development operations.

The following table sets forth Greiner's restructuring accruals as of December
31, 1995:

To The Board of Directors

Suite 1900 LB 44
Irving, TX  75039-3907

Gentlemen:

         We understand that pursuant to the Agreement and Plan of Merger Among
Greiner Engineering, Inc. ("Greiner" or the "Company"), URS Corporation
("URS"), and URS Acquisition Corporation, the "Merger Agreement", Greiner plans
to merge into and become a wholly owned subsidiary of URS, (the "Merger").  We
further understand that ownership in Greiner is currently represented by
4,704,642 shares of common stock issued and outstanding, 121,092 shares are
issued and held in treasury, and 377,650 options for common stock issued and
outstanding.  Moreover, we understand that ownership of URS is represented by
7,167,591 shares of common stock  issued and outstanding, with 287,000 shares
of common stock issued but held in treasury.    Finally, we understand upon the
close of the Merger, each share of Greiner's common stock will be converted
into the right to receive consideration (the "Consideration") as follows: (i)
0.298 shares of URS common stock; and (ii) $13.50 in cash; all of which shall
be payable upon the surrender of the certificates representing such shares of
Greiner stock.  The Merger, the payment of the Consideration in exchange for
Greiner's common stock, and all related transactions disclosed to Houlihan
Lokey Howard & Zukin are referred to collectively herein as the "Transaction."

         You have requested our opinion (the "Opinion") as to the matters set
forth below.  The Opinion does not address the Company's underlying business
decision to effect the Transaction. We have not been requested to, and did not,
solicit third party indications of interest in acquiring all or any part of the
Company.  Furthermore, at your request, we have not negotiated the Transaction
or advised you with respect to alternatives to it.

         In connection with this Opinion, we have made such reviews, analyses
and inquiries as we have deemed necessary and appropriate under the
circumstances.  Among other things, we have:

         1.      reviewed the Company's annual reports to shareholders and on
Form 10-K for the five fiscal years ended December 31, 1994 and quarterly
reports on Form 10-Q for the three quarters ended September 30, 1995, and
Company- prepared interim financial statements for the period ended November
30, 1995, which the Company's management has identified as being the most
current financial statements available;

         2.      reviewed URS's annual reports to shareholders and on Form 10-K
for the four fiscal years ended October 31, 1994, a draft of Form 10-K for the
fiscal year ended October 31, 1995, and quarterly reports on Form 10-Q for the
three quarters ended July 31, 1995;

         3.      reviewed a copy of  the Merger Agreement dated January 10,
1996;

         4.      reviewed a copy of the Company's latest proxy statement;

         5.      met with certain members of the senior management of the
Company and URS to discuss the operations, financial condition, future
prospects and projected operations and performance of the Company, and met with
representatives of the Company's  counsel to discuss certain matters;

         6.      visited certain facilities and business offices of the
Company;

         7.      reviewed the 1996 business plans for the Company's principal
offices and divisions, and forecasts and projections prepared by the Company's
management with respect to the Company for the years ended December 31, 1996
through 2002;

         8.      reviewed the historical market prices and trading volume for
the Company's and URS's publicly traded securities;

         9.      reviewed certain other publicly available financial data for
certain companies that we deem comparable to the Company, and publicly
available prices and premiums paid in other transactions that we considered
similar to the Transaction;

         10.     conducted such other studies, analyses and inquiries as we
have deemed appropriate.

         We have relied upon and assumed, without independent verification,
that the financial forecasts and projections provided to us have been
reasonably prepared and reflect the best currently available estimates of the
future financial results and condition of the Company, and that there has been
no material change in the assets, financial condition, business or prospects of
the Company since the date of the most recent financial statements made
available to us.

         We have not independently verified the accuracy and completeness of
the information supplied to us with respect to the Company and do not assume
any responsibility with respect to it.  We have not made any physical
inspection or independent appraisal of any of the properties or assets of the
Company. Our opinion is necessarily based on business, economic, market and
other conditions as they exist and can be evaluated by us at the date of this
letter.

         Based upon the foregoing, and in reliance thereon, it is our opinion
that the Consideration to be received by the public stockholders of the Company
in connection with the Transaction is fair to them from a financial point of
view.

                                   ARTICLE 1.

of the Merger under the laws of the State of Nevada under the name of Greiner
Engineering, Inc., and Greiner shall succeed to and assume all the rights and
obligations of the Subsidiary in accordance with the Nevada Law.

         Section 1..2  Effective Time of the Merger.  Subject to the provisions
of this Agreement, as soon as practicable after the Closing Date, the parties
shall file articles of merger, certificate of merger or other appropriate
documents (in any such case, the "Merger Documents"), executed in accordance
with the relevant provisions of the Nevada Law and shall make all other filings
or recordings required under the Nevada Law.  The Merger shall become effective
at such time as the Merger Documents are duly filed with the Secretary of State
of the State of Nevada, or at such other time as the parties hereto shall agree
should be specified in the Merger Documents (the "Effective Time of the
Merger").

         Section 1..3  Effects of the Merger.  At the Effective Time of the
Merger:

                 (a)      the separate corporate existence of the Subsidiary
shall cease and the Subsidiary shall be merged with and into Greiner, which

Merger, subject to the liabilities of the Subsidiary as of the Effective Time
of the Merger;

                 (b)      the Articles of Incorporation of Greiner, as in
effect immediately prior to the Effective Time of the Merger, shall be the

thereafter as provided by law;

                 (c)  the by-laws of Greiner, as in effect immediately prior to
the Effective Time of the Merger, shall be the by-laws of the Surviving

terms and as provided by law;

                 (d)      the directors of the Subsidiary immediately prior to
the Effective Time of the Merger shall be the directors of the Surviving
Corporation, each of such directors to hold office, subject to the applicable
provisions of the Articles of Incorporation and by-laws of the Surviving
Corporation, until the next annual stockholders' meeting of the Surviving

the Effective Time of the Merger, any of the foregoing persons shall for any
reason be unwilling or unable to serve, the resulting vacancy shall be filled
as provided in such by-laws;

                 (e)      the officers of Greiner immediately prior to the

<PAGE>   141
Surviving Corporation and until their successors are elected and duly
qualified; and

                 (f)      the Surviving Corporation shall possess all the
rights, privileges, immunities, powers and purposes of each of the Constituent
Corporations; and all the property, real, personal or mixed, including causes
of action and every other asset of each of the Constituent Corporations, shall
vest in the Surviving Corporation without further act or deed.  The Surviving
Corporation shall be responsible and liable for all liabilities and obligations
of each of the Constituent Corporations.  No liability or obligation due or to
become due, claim or demand for any cause existing against either of the
Constituent Corporations, or any stockholder, officer or director thereof,
shall be released or impaired by the Merger.  No action or proceeding, whether
civil or criminal, then pending by or against the Constituent Corporations, or
any stockholder, officer or director thereof, shall abate or be discontinued by
the Merger, but may be enforced, prosecuted, settled or compromised as if the
Merger had not occurred, or the Surviving Corporation may be substituted in
such action 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 Greiner Common Stock.

                 (a)      Conversion; Merger Consideration.  At the Effective
Time of the Merger, each share of the Greiner Common 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 into the right to receive (i) 0.298 shares of the URS Common
Stock, and (ii) $13.50 in cash, all of which shall be payable upon the
surrender of the certificate(s) formerly representing such shares of Greiner
Common Stock.  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
Greiner Common 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)      Options. At the Effective Time of the Merger, all
options to purchase Greiner Common Stock (the "Greiner Options") issued under
the 1981 Stock Option Plan of Greiner Engineering, Inc. (the "1981 Greiner
Plan") or under the 1991 Stock Option Plan of Greiner Engineering, Inc. (the
"1991 Greiner Plan") which remain outstanding at that time (whether or not
previously exercisable or vested) shall, by virtue of the Merger, and without
any further action on the part of Greiner or any holder of said Greiner
Options, be cancelled.  If, at the Effective Time of the Merger, the Exercise
Price per share with respect to any Greiner Option (whether or not previously
exercisable or vested) so cancelled (the "Exercise Price") is less than the sum
of (x) $13.50 per share, plus (y) 0.298 multiplied by the closing price per
share of the URS Common Stock as reported on the New York Stock Exchange on the
trading day immediately





                                      -3-
<PAGE>   142
preceding the Closing Date as listed in The Wall Street Journal (the "Merger
Value"), then the holder of such Greiner Option shall be paid as soon as
practicable following the Closing Date cash in an amount per each share of
Greiner Common Stock subject to such option equal to the excess, if any, of the
Merger Value over the Exercise Price.  Notwithstanding anything to the contrary
in this Section 2.1(c), pursuant to the terms of Section 6(b) of the 1981
Greiner Plan and Section 6(b) of the 1991 Greiner Plan, promptly following
execution of this Agreement, Greiner shall give each holder of the Greiner
Options (whether or not previously exercisable or vested) written notice that
such Greiner Options will be cancelled in connection with the Merger and, shall
permit said holders to exercise their Greiner Options and purchase Greiner
Common Stock pursuant to the terms of the 1981 Greiner Plan and/or the 1991
Greiner Plan, as the case may be.

                 (d)      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
Greiner (the "Exchange Agent"), for the benefit of holders of the Greiner
Common 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 Greiner Stockholders.    As soon as
reasonably practicable after the Effective Time of the Merger, URS shall cause
the Exchange Agent to mail to each holder of record of a certificate or
certificates representing the Greiner Common 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 Greiner Common Stock shall pass, only
upon delivery of the certificates for the shares of the Greiner Common 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 Greiner Common Stock in
exchange for the Merger Consideration.

                          (3)     Surrender of Greiner Stock Certificates.
Upon surrender of a certificate for shares of the Greiner Common Stock (a
"Greiner 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
Greiner Common Stock is entitled pursuant to this Article 2 plus that portion
of 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 Greiner Stock Certificate for the shares of the Greiner Common
Stock so surrendered shall forthwith be cancelled.

                          (4)     Limitations.  Notwithstanding any other
provision of this Agreement, until holders of Greiner Stock Certificates
representing shares of the Greiner Common 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
Greiner Stock Certificates are surrendered for exchange as provided herein,





                                      -4-
<PAGE>   143
no interest shall be paid on any dividends or other distributions or any
payment for fractional shares.  Upon surrender of a Greiner Stock Certificate,
there shall be paid to the holder of such Greiner 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 Greiner 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 Greiner
Stock Certificate surrendered in exchange therefore 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 Greiner Stock Certificate surrendered, or establish to the
satisfaction of Greiner that such tax has been paid or is not applicable.
Certificates of URS Common Stock issued to holders of Greiner Common Stock
issued under a Greiner restricted stock plan shall bear legends substantially
similar to the legends presently on the Greiner Common Stock Certificates and
as required by applicable law.

                          (5)     Payment.  The Exchange Agent shall within 15
business days of receipt of such Greiner 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 Greiner Stock Certificate so
surrendered shall be cancelled.  In the event of a transfer of ownership of
shares of Greiner Common Stock that is not registered in the transfer records
of Greiner, 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
Greiner Stock Certificate or establish to the satisfaction of the Greiner that
such tax has been paid or is not applicable.  Until surrendered as contemplated
by this Section 2.1, each Greiner 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 Greiner Stock Certificate
shall be converted pursuant to Section 2.1.  No interest will be paid or will
accrue on the cash payable upon the surrender of any Greiner Stock Certificate.

                 (e)      Cancellation of the Greiner Common Stock.  At the
Effective Time of the Merger, all of the authorized and outstanding shares of
the Greiner Common Stock shall be cancelled and cease to represent any interest
in Greiner and such holders shall cease to have any rights of a stockholder of
Greiner.  From and after the Effective Time of the Merger, the holders of
shares of the Greiner Common 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 Greiner Common 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 Greiner Common
Stock has been converted.

         Section 2..2  Conversion of the 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 be

stock of the Surviving Corporation.

                   REPRESENTATIONS AND WARRANTIES OF GREINER

         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 "Greiner Disclosure Letter"), Greiner represents and
warrants to URS and the Subsidiary as follows:

         Section 4..1  Organization.  Each of Greiner and the Greiner
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 Greiner Material
Adverse Effect (as defined below).  Each of Greiner and the Greiner
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 Greiner Material Adverse Effect
(defined below) on the Business Condition (defined below) of Greiner.  For
purposes of this Agreement:  (a) "Greiner Material Adverse Effect" means, when
used in connection with Greiner, any change or effect that is materially
adverse to the Business Condition of Greiner, 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; and  (b)
"Business Condition" with respect to an entity shall mean the business,
financial condition, results of operations, or assets (without giving effect to
the consequences of the transactions contemplated by this Agreement) of such
entity and its Subsidiaries taken as a whole.

         Section 4..2  Capitalization.  The authorized capital stock of Greiner
consists of 20,000,000 shares of Greiner Common Stock, par value $0.50 per
share, and 1,000,000 shares of preferred stock, par value $1.00 per share (the
"Greiner Preferred Stock").  As of the date hereof, (i)





                                      -6-
<PAGE>   145
4,704,642 shares of Greiner Common Stock are issued and outstanding, (ii)
options to acquire 377,650 shares of Greiner Common Stock are outstanding under
all stock option plans and agreements of Greiner, (iii) 737,300 shares of
Greiner Common Stock (including shares of Greiner Common Stock issuable upon
exercise of the options identified in clause (ii) above) are reserved for
issuance pursuant to all employee plans of Greiner, and (iv) there are no
shares of Greiner Preferred Stock outstanding.  All of the issued and
outstanding shares of Greiner Common 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 Greiner Disclosure Letter, as of the date of
this Agreement there are no shares of capital stock of Greiner issued or
outstanding or any options, warrants, subscriptions, calls, rights, convertible
securities or other agreements or commitments obligating Greiner 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 Greiner Disclosure Letter, after the Effective Time
of the Merger, Greiner 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 Greiner Disclosure
Letter identifies each corporation or other entity of which Greiner, 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 "Greiner Subsidiary")
and sets forth for each Greiner  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.  Greiner 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 Greiner Subsidiary) of each of the Greiner  Subsidiaries.  Each of the
outstanding shares of capital stock of each of the Greiner Subsidiaries is duly
authorized, validly issued, fully paid and nonassessable.  Each of the
outstanding shares of capital stock of each Greiner Subsidiary is owned,
directly or indirectly, by Greiner, free and clear of all liens, pledges,
security interests, claims, or other encumbrances of any nature 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 Greiner  Subsidiaries; or
(b) any agreements or contractual commitments obligating Greiner, or
restricting Greiner's rights, to transfer, sell, or vote, the capital stock of
the Greiner  Subsidiaries owned by it, directly or indirectly.

         Section 4..4  Material Investments.  Except as set forth in Section
4.4 of the Greiner Disclosure Letter, Greiner 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 Greiner Subsidiary), partnership, joint venture or
other business association or entity that is material to Greiner.  With respect
to those entities indicated on Section 4.4 of the Greiner Disclosure Letter,
Greiner 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 Greiner, 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 Greiner Disclosure Letter), the financial
condition





                                      -7-
<PAGE>   146
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 Greiner's disclosures with respect to its
investment in each such entities otherwise included in the Greiner SEC 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 Greiner Disclosure Letter, Greiner (or, as indicated
thereon, a Greiner Subsidiary) has good and marketable title to the securities
evidencing its investment in the entities indicated in Section 4.4 of the
Greiner Disclosure Letter, which have been validly issued and are fully paid
and nonassessable and are held by Greiner or a Greiner Subsidiary free and
clear of any Lien, restraint on alienation, or any other restriction with
respect of the transferability or assignability thereof (other than
restrictions on transfer imposed by Federal or state securities laws).

         Section 4..5  Authority Relative to this Agreement.  Greiner has all
requisite corporate power and authority to enter into this Agreement and
subject, in the case of this Agreement, to approval of this Agreement by the
stockholders of Greiner and to the consents and approvals set forth in Section
4.6 below, to consummate the transactions contemplated hereby.  The execution,
delivery and performance of this Agreement by Greiner and the consummation by
Greiner of the transactions contemplated hereby have been duly authorized by
all necessary corporate action on the part of Greiner, including the unanimous
approval of the Board of Directors of Greiner, and no other corporate
proceedings on the part of Greiner are necessary to authorize this Agreement or
the transactions contemplated hereby (except for approval by the stockholders
of Greiner).  This Agreement has been duly and validly executed and delivered
by Greiner and constitutes a valid and binding agreement of Greiner,
enforceable against Greiner 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 4..6  Consents and Approvals; No Violations.  Except for

the provisions hereof, will (i) conflict with or result in any breach of any
provisions of the Articles of Incorporation or By-Laws of Greiner or the
Articles or Certificate of Incorporation, as the case may be, or By-Laws of any

bound or affected, (iii) except as set forth in Section 4.6(iii) of the Greiner

and (v) for violations, breaches, defaults, terminations, cancellations,
accelerations, creations, impositions, suspensions or revocations which would
not individually or in the aggregate have a Greiner Material Adverse Effect.

         Section 4..7  Greiner SEC Reports and Financial Statements.  Greiner
has delivered or made available to URS 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 the Securities and
Exchange Commission ("SEC") since January 1, 1992 (collectively, the "Greiner
SEC Reports").  Except as set forth in Section 4.7 of the Greiner Disclosure
Letter, as of the respective dates such Greiner SEC Reports were filed or, if
any such Greiner SEC Reports were amended, as of the date such amendment was
filed, each of the Greiner 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 Greiner (including any
related notes and schedules) included (or incorporated by reference) in its
Annual Reports on Form 10-K for each of the three fiscal years ended December
31, 1992, 1993 and 1994 and Quarterly Reports on Form 10-Q for all interim

indicated in the notes thereto), the consolidated financial position of Greiner
and the Greiner 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 Greiner's accounting policies or the methods of making
accounting estimates or changes in estimates that are material to the Greiner
Financial Statements, except as described in the notes thereto.

         Section 4..8  Information Supplied.  None of the information supplied

URS Common Stock in or as a result of the Merger (the "Form S-4"), or (b) the
proxy statement and any amendment or supplement thereto to be distributed in
connection with Greiner's meeting of stockholders to vote upon this Agreement

of the Form S-4, as amended or supplemented, (x) at the time it becomes
effective, (y) at the time of any post-effective amendment thereto, and (z) at
the time of the meeting of the stockholders of Greiner, 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.  Greiner
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 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 Greiner's stockholders to the extent required by applicable
law.  The Proxy Statement/Form S-4 shall comply as to form in all material
respects with the provisions of all applicable laws, including the provisions
of the Exchange Act and the rules and regulations of the SEC thereunder, except
that no representation is made by Greiner with respect to information supplied
by URS specifically for inclusion therein.

the Greiner Disclosure Letter, since September 30, 1995, Greiner and the
Greiner Subsidiaries 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 Greiner Material Adverse Effect, or any
development or combination of developments of which Greiner has knowledge that
is reasonably likely, in Greiner's commercially reasonable judgment, to result
in a Greiner Material Adverse Effect, (b) any declaration, setting aside or
payment of any dividend or other capital distributions in respect of any of its

increase in the regular compensation of any of the officers or employees of
Greiner or the Greiner Subsidiaries, except such increases as have been granted
in the ordinary course of business in accordance with its customary practices

Greiner or any of the Greiner Subsidiaries of any indebtedness for borrowed
money other than in the ordinary course of business consistent with past

material to Greiner'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 Greiner or any of the Greiner
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 Greiner or the Greiner Subsidiaries which has resulted
or is reasonably likely to result in a Greiner Material Adverse Effect, or (h)

Section 4.9.

         Section 4..10  Litigation.  Except for litigation disclosed in the
notes to the financial statements included in the Greiner SEC Reports or as set
forth in Section 4.10 of the Greiner 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 Greiner, threatened
against or affecting Greiner or any of the





                                      -10-
<PAGE>   149
Greiner Subsidiaries, the outcome of which, in the reasonable judgment of
Greiner, is likely individually or in the aggregate to have a Greiner 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 Greiner or any of the Greiner
Subsidiaries having, or which, insofar as can reasonably be foreseen, in the
future may have, any such effect.

         Section 4..11  Absence of Undisclosed Liabilities.  Except for
liabilities or obligations which are accrued or reserved against in the Greiner
Financial Statements (or reflected in the notes thereto) or which were incurred
after September 30, 1995 in the ordinary course of business and consistent with
past practices or in connection with the transactions contemplated by this
Agreement, Greiner and the Greiner 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
Greiner Disclosure Letter, neither Greiner nor any of the Greiner Subsidiaries
is in violation or breach of, or default under (and 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 Articles or
Certificate of Incorporation, as the case may be, or By-Laws, (b) any note,
bond, mortgage, deed of trust, security interest, indenture, license, contract,

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 defaults which would not individually or in the aggregate have a Greiner
Material Adverse Effect.

         Section 4..13  Properties, Liens, Etc.  Greiner and the Greiner
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
which, if exercised upon default, would have a Greiner Material Adverse Effect.
All plants, structures and material equipment owned or leased by Greiner or the
Greiner 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 Greiner nor any of the Greiner Subsidiaries have

                                      -12-
<PAGE>   151
of material modifications for each Greiner Plan for which a summary plan
description is required; (v) if the Greiner Plan is funded through a trust or
any third party funding vehicle, a copy of the trust 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 Greiner Plan.  Each of the Greiner 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 Greiner
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 Greiner Disclosure Letter lists each
Greiner Benefit Arrangement.  With respect to each of the Greiner Benefit
Arrangements, Greiner 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 Greiner 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 Greiner Benefit Arrangement, including Federal and state
securities laws.

         (c)     Neither Greiner nor the Greiner Subsidiaries nor any of their
ERISA Affiliates has been involved in any transaction, taken any action, or
failed to take any action that could cause Greiner or the Greiner Subsidiaries
to be subject to any liability that would likely cause a Greiner Material
Adverse Effect.  No fiduciary of any Greiner Plan or Greiner 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 Greiner, the Greiner Subsidiaries or URS.

         (d)     Except with respect to contributions to Greiner Plans under
Section 412 that are current and not past due, neither Greiner nor the Greiner
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 Greiner, the Greiner 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 Greiner and the
Greiner 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.

         (g)     No Greiner Plan or Greiner 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





                                      -13-
<PAGE>   152
to current or former employees of Greiner and the Greiner 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 Greiner 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 Greiner or the Greiner 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 Greiner Plans and Greiner 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 Greiner
Plans or Greiner Benefit Arrangements.  No Greiner Plans or Greiner 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
Greiner Plan with the Internal Revenue Service under its Voluntary Compliance
Resolution program, its Closing Agreement Program, or other similar programs.

         (j)     No "prohibited transaction," as such term is defined in Code
Section 4975 and ERISA Section 406, has occurred with respect to any Greiner
Plan or Greiner Benefit Arrangement that could subject such plan, any fiduciary
thereof, Greiner, the Greiner Subsidiaries or URS to a material penalty for
such prohibited transaction imposed by ERISA Section 502 or a material tax
imposed by Code Section 4975.

         (k)     Any bonding required by applicable provisions of ERISA with
respect to any Greiner Plan or Greiner Benefit Arrangement has been obtained
and is in full force and effect.

         (l)     For purposes of this Section 4.15:

                          (1)     "Greiner Benefit Arrangement" means each

benefits, disability benefits, death benefits, retirement benefits, deferred
compensation, profit-sharing, bonuses, stock options, stock purchase, phantom
stock, stock appreciation or other forms of incentive compensation or
postretirement insurance or health benefits, compensation or benefits that (i)
is not a Greiner Plan, (ii) is or has been entered into, maintained, or
contributed to by Greiner or its ERISA Affiliates, and (iii) covers, or within
the last five years covered and has further or continuing obligations, any
employee of Greiner or any Greiner Subsidiary.

                          (2)     "Greiner Plan" means any Employee Benefit
Plan or "multiemployer plan" as defined in Section 4001(a)(3) of ERISA

<PAGE>   153
(a) maintained or contributed to by or on behalf of Greiner or any Greiner
Subsidiary, whether currently or within the six years prior to the Closing
Date, or (b) in which any employee of Greiner or any Greiner Subsidiary has
participated, as an employee of Greiner or any Greiner Subsidiary, within the
six years prior to the Closing Date, or under which any such employee has
accrued and remains entitled to any benefit.

                          (3)     "Employee Benefit Plan" means any deferred
compensation, retirement, severance, health, or other plan or program
constituting an "employee benefit plan" as defined in Section 3(3) of ERISA

or the Greiner  Subsidiaries, or any ERISA Affiliate of Greiner or the Greiner
Subsidiaries or in which any such employees participate or participated, other
than a Multiemployer Plan.

                          (4)     "ERISA" means the Employee Retirement Income
Security Act of 1974, as amended, and all regulations and published
interpretations promulgated thereunder, as in effect from time to time.

                          (5)     "ERISA Affiliate" means each person (as
defined in Section 3(9) of ERISA) that, together with Greiner or a Greiner
Subsidiary, would be treated as a single employer under Section 4001(b) of
ERISA or that would be deemed to be a member of the same "controlled group"
within the meaning of Section 414(b), (c), (m), and (o) of the Code (provided,
however, that when the subject of the provision is a Multiemployer Plan only
subsections (b) and (c) of Section 414 shall be taken into account).

         Section 4..16  Employment Matters; Labor Relations.

                 (a)      Section 4.16 of the Greiner Disclosure Letter  sets
forth a true and complete list of the names, classifications, dates of hire and
base compensation for the year ending December 31, 1995, of each employee of
Greiner and the Greiner Subsidiaries whose base compensation exceeds $75,000
per annum.

                 (b)      With respect to current or former employees of
Greiner and the Greiner Subsidiaries,

                          (i)     Each of Greiner and the Greiner Subsidiaries
is in substantial compliance with all applicable laws respecting employment and
employment practices, and occupational safety and health, except for such
violations, if any, that in the aggregate have not had and would not have a
Greiner Material Adverse Effect.  There is no charge or compliance action
pending or threatened against or with respect to Greiner or any of the Greiner
Subsidiaries before the Equal Employment Opportunity Commission or any state,
local, or foreign agency responsible for the prevention of unlawful employment
practices as to which there is a reasonable likelihood of adverse
determination.  None of Greiner nor any of the Greiner Subsidiaries has
received notice of the intent of any Federal, state, local or foreign agency
responsible for the enforcement of labor or employment laws to conduct an
investigation, and, to Greiner's knowledge, no such investigation is in
progress.

                          (ii)    The employees of Greiner and the Greiner
Subsidiaries are not represented by any labor union, nor are there any
collective bargaining agreements or any other types of agreements with labor
unions otherwise in effect with respect to such employees, nor are any
collective bargaining agreements currently being negotiated, and, to Greiner's

regulation.  There is no unfair labor





                                      -15-
<PAGE>   154
practice charge or complaint against any of Greiner or the Greiner Subsidiaries
pending or, to Greiner's knowledge, threatened before the National Labor
Relations Board.  There is no labor strike, lockout, slow-down or work stoppage
pending or threatened against Greiner or any of the Greiner Subsidiaries.  None
of Greiner and the Greiner Subsidiaries has experienced any significant work
stoppage or been party to any proceedings before the National Labor Relations
Board for the past three years.

         Section 4..17  Intellectual Property.

                 (a)      Except as set forth in Section 4.17 of the Greiner
Disclosure Letter, and except to the extent that the inaccuracy of any of the
following (or the circumstances giving rise to such inaccuracy), individually
and in the aggregate, would not have a Greiner Material Adverse Effect:

                          (i)     Greiner and the Greiner Subsidiaries own, or
are licensed or otherwise have the right to use (in each case, clear of any
lien or encumbrance of any kind) all Intellectual Property (as defined below)
that in any material respect is used or proposed to be used in the business of
Greiner and the Greiner Subsidiaries.

                          (ii)    No claims are pending, or to the knowledge of
Greiner, threatened that Greiner or any of the Greiner Subsidiaries is
infringing on or otherwise violating the rights of any person with regard to
any Intellectual Property owned by and/or licensed to Greiner or the Greiner
Subsidiaries.

                          (iii)   To the knowledge of Greiner, no person is
infringing on or otherwise violating any right of Greiner or any Greiner
Subsidiary with respect to any Intellectual Property owned by and/or licensed
to Greiner or the Greiner Subsidiaries, provided, that the foregoing
representation is qualified to the extent of publicly known problems of general
applicability with respect to software piracy and copyright protection.

                          (iv)    None of the former or current members of
management or key personnel of Greiner or any Greiner Subsidiary, including all
former and current employees, agents, consultants and contractors who have
contributed to or participated in the conception and development of designs,
computer software or other Intellectual Property of Greiner or the Greiner
Subsidiaries, has asserted in writing any claim against Greiner or any of the
Greiner Subsidiaries in connection with the involvement of such persons in the
conception and development of any design, computer software or other
Intellectual Property, and no such claim, to the knowledge of Greiner, has been
threatened.

                          (v)     The execution and delivery of this Agreement,
compliance with its terms and the consummation of the transactions contemplated
hereby do not and will not conflict with or result in any violation or default
(with or without notice or the lapse of time) or give rise to any right,
license or encumbrance relating to the Intellectual Property, or any right of
termination, cancellation, or acceleration of any material Intellectual
Property right or obligation.

                 (b)      For purposes of this Agreement, "Intellectual
Property" means (a) trademarks (registered on unregistered), service marks,
brand names, certification marks, trade dress, assumed names, trade names and

information and rights in any jurisdiction to limit the use or disclosure
thereof by any person; (d) writings and other works, whether copyrighted,
copyrightable or not in any jurisdiction; (e) registration or applications for
registration of copyrights in any jurisdiction, and any renewals or extensions
thereof; (f) any similar intellectual property or proprietary rights and

(g) licenses, immunities, covenants not to sue and the like relating to the
foregoing; and (h) any claims or causes of action arising out of or related to
any infringement or misappropriation of any of the foregoing.

                 (c)      Except for the name "Greiner" and the Greiner logo,
there are no (i) material domestic and foreign registered trademarks,
registered copyrights and patents, and applications for registration of any of
the foregoing; (ii) material trade names, service marks, service names, logos
and assumed names which are owned by Greiner or any of the Greiner
Subsidiaries, as the case may be, and that are used or proposed to be used in
the business of Greiner and the Greiner Subsidiaries as currently conducted; or
(iii) material licenses and other agreements to which Greiner or any Greiner
Subsidiary is a party and pursuant to which Greiner is authorized to use any
Intellectual Property.  To the knowledge of Greiner, all registered

Neither Greiner nor the Greiner Subsidiaries have taken or omitted to take any
act which act or omission might have the effect of waiving or impairing any of
the rights of Greiner to practice and enforce any patent, or to use and enforce
any trademark or copyright listed on Section 4.17 of the Greiner Disclosure
Letter.

         Section 4..18  Insurance.  Section 4.18 of the Greiner Disclosure
Letter contains a complete and correct list and accurate summary description of
all insurance policies and material completion bonds (including, without
limitation, professional liability coverage) maintained by or on behalf of or
covering Greiner and the Greiner Subsidiaries, their assets or operations, or
the conduct of their business.  Greiner has made available to URS complete and
correct copies of all the declaration sheets or binders (if declaration sheets
are not yet issued) relating to such policies and bonds.  Except as noted on
Section 4.18 of the Greiner Disclosure Letter, all such policies and bonds are
in full force and effect, no notices of cancellation or nonrenewal have been
received with respect thereto, and all premiums due thereon have been paid.
Greiner and the Greiner Subsidiaries have complied in all material respects
with the provisions of such policies and bonds.  Such policies and bonds are of
the type and in amounts customarily carried by persons conducting businesses
similar to the business conducted by Greiner and the Greiner Subsidiaries.

         Section 4..19.  Compliance with Applicable Law.  Greiner and the

ordinances, rules and regulations of any court, administrative agency or
commission or other governmental authority or instrumentality, whether domestic
or foreign (each a "Governmental Entity")  applicable to Greiner or any Greiner
Subsidiary, except for such violations, if any, that, in the aggregate, have
not had and would not, in the reasonable judgment of Greiner, be likely to have
a Greiner Material Adverse Effect.

principal amount of $1,000,000 or more;

                 (d)      Each other agreement, license or franchise which has
not been terminated or performed in its entirety and not renewed which may be,
by its terms, terminated, impaired or adversely affected by reason of the
execution of this Agreement, the closing of the Merger, or the consummation of
the transactions contemplated hereby or thereby, and the loss of which would,
individually or in the aggregate with other such agreements, licenses, or
franchises, have a Greiner Material Adverse Effect;

                 (e)      Each agreement of Greiner or the Greiner Subsidiaries
with or for the benefit of any affiliate of Greiner with annual payments of
$50,000 or more;

All Material Agreements are valid, binding and enforceable in accordance with
their terms and none of Greiner or the Greiner  Subsidiaries nor, to the
knowledge of Greiner, any other party thereto, is in default under any of such
agreements, nor, to the knowledge of Greiner, has any event or circumstance
occurred that, with notice or lapse of time or both, would constitute any event
of default by Greiner or the Greiner 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 Greiner Material Adverse
Effect.  To Greiner's knowledge, none of the parties to the contracts

reduce materially or terminate presently or in the future, such contracts.

         Section 4..21  Prohibited Payments.  Greiner has not, with respect to

                                      -18-
<PAGE>   157
and with all applicable Environmental Laws, except where the failure to hold
such permits or to be in compliance would not have a Greiner Material Adverse
Effect.

Greiner Subsidiaries has received any written request for information, or has

to any (1) alleged violation by Greiner or any of the Greiner Subsidiaries of
any Environmental Law or liability thereunder or (2) alleged failure by Greiner
or any of the Greiner Subsidiaries to have any Environmental Permit, except, in
each case, for Environmental Notices that would not have a Greiner Material
Adverse Effect.

                                  (iv)     To Greiner's knowledge, there have
been no discharges, emissions or releases of Hazardous Substances by Greiner

discharges, emissions or releases that would not have a Greiner Material
Adverse Effect.

                          (b)     There has been no material environmental
investigation of Greiner, study, audit, test, review or other analysis
(including any Phase I environmental assessments) conducted of which Greiner
has knowledge in relation to any real property or lease which has not been
delivered to URS prior to the date hereof.  Neither Greiner nor any of the
Greiner Subsidiaries is subject to any judgment, decree or order relating to
compliance with, or the cleanup of regulated substances under, any applicable
Environmental Law.

                          (c)     For purposes of this Agreement:  (i) the term

<PAGE>   158
Administration ("OSHA"), and any other Federal, state, local or foreign
governmental authorities with jurisdiction and all regulatory approvals in
respect thereof are in full force and effect on the date hereof, the failure to

Greiner Material Adverse Effect.

                          (a)     Greiner has fully complied with the

The Board of Directors of Greiner (at a meeting duly called and held or
pursuant to valid written consent) has unanimously determined that the

Greiner and its stockholders.  Greiner has received the opinion of Houlihan,
Lokey, Howard & Zukin, Inc. ("HL"), Greiner's financial advisor, or another
financial advisor selected by Greiner and reasonably acceptable to URS,
substantially to the effect that the Merger consideration to be paid to holders
of the Greiner Common Stock in the Merger is fair to such stockholders from a
financial point of view.

                 Section 4..27    Brokers.  No broker, finder or investment
banker is entitled to any brokerage, finder's fee or commission payable by
Greiner in connection with the transactions contemplated by this Agreement

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

                 Section 4..29    Reliance.  The foregoing representations and
warranties are made by Greiner with the knowledge and expectation that URS is
placing reliance thereon.


                                   ARTICLE 5.

                     REPRESENTATIONS AND WARRANTIES OF URS

                 Except as otherwise disclosed to Greiner 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 "URS Disclosure Letter"), URS and the
Subsidiary represent and warrant to Greiner as follows:

                 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





                                      -20-
<PAGE>   159
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 on the Business Condition of URS.  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 Condition
of URS, 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) 7,167,591 shares of URS
Common Stock are issued and outstanding, (ii) options to acquire 1,166,324
shares of URS Common Stock are outstanding under all stock option plans and
agreements of URS, (iii) 1,559,665 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 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.  All of the URS Common
Stock reserved for issuance in exchange for the shares of the Greiner Common
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.  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, subscriptions, calls, rights, convertible securities or
other agreements or commitments obligating URS 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
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 or
foreign laws relating to takeovers, if applicable, 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 Nevada 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 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 their properties or assets may be bound or affected,
(iii) except as set forth 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 Greiner 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 three fiscal years ended October
31, 1992, 1993 and 1994, and to be included on Form 10-K for the fiscal year
ended October 31, 1995, 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





                                      -22-
<PAGE>   161
(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.

                 Section 5..6  Information Supplied.  None of the information
supplied or to be supplied by URS, the URS Subsidiaries, auditors, attorneys,
financial advisors, other consultants or advisors or the Subsidiary for
inclusion in the Form S-4 or the Proxy Statement/Form S-4, will, in the case of
the Proxy Statement and any amendment or supplement thereto, at the time of the
mailing of the Proxy Statement and any amendment or supplement thereto, and at
the time of any meeting of stockholders of Greiner to vote upon this Agreement
and the transactions contemplated hereby, or in the case of the Form S-4, as
amended or supplemented, at the time it becomes effective and at the time of
any post-effective amendment thereto contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in
which they are made, not misleading or necessary to correct any statement in
any earlier filing with the SEC of such Proxy Statement/Form S-4 or any
amendment or supplement thereto or any earlier communication (including the
Proxy Statement/Form S-4) to stockholders of Greiner with respect to the
transactions contemplated by this Agreement.  The Form S-4 and the Proxy
Statement/Form S-4 will comply as to form in all material respects with the
provisions of all applicable laws including the provisions of the Securities
Act and the Exchange Act and the rules and regulations of the SEC thereunder,
except that no representation is made by URS with respect to information
supplied by Greiner specifically for inclusion therein.

                 Section 5..7  Board Approvals; Opinion of Financial Advisor.
The Boards of Directors of URS and the Subsidiary (at meetings duly called and
held or pursuant to valid written consents) have unanimously determined that
the transactions contemplated hereby are fair to and in the best interests of
URS and the Subsidiary and the stockholders of URS.  URS has received the
opinion of Morgan Stanley & Co. Incorporated ("MS"), URS's financial advisor,
substantially to the effect that the Merger consideration to be paid to holders
of the Greiner Common Stock in the Merger is fair to URS from a financial point
of view.

                 Section 5..8  Brokers.  No broker, finder or investment
banker (other than MS) is entitled to any brokerage, finder's fee or commission
payable by URS in connection with the transactions contemplated by this
Agreement based upon arrangements made by or on behalf of URS.

                 Section 5..9  Disclosure.  No representation or warranty by
URS in this Agreement, the schedules hereto or any certificates delivered
pursuant to the terms hereof, contains or will contain an untrue statement of
material fact, or omits or will omit to state a material fact necessary to make
the statements contained herein or therein, in light of the circumstances in
which they were made, not misleading.

the HSR Act.  Each party shall use its best efforts to obtain all such
authorizations, approvals and consents.

                                  6..1.3  Confidentiality.    Each party shall
hold in confidence all nonpublic information until such time as such
information is otherwise publicly available and, if this Agreement is
terminated, each party will deliver to the other all documents, work papers and
other materials (including copies) obtained by such party or on its behalf from
the other party as a result of this Agreement or in connection herewith,
whether so obtained before or after the execution hereof.  Each party shall
continue to abide by the terms of the confidentiality agreement between URS and
Greiner in effect as of the date hereof.

                                  6..1.4 Best Efforts.  Upon the terms and
subject to the conditions herein provided, each of the parties hereto agrees to
use its best efforts to take or cause to be taken all actions, to do or cause
to be done, and to assist and cooperate with the other party hereto in doing,
all things necessary, proper or advisable under applicable laws and
regulations, to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this Agreement, including (i)
using all reasonable efforts to obtain all necessary waivers, consents and
approvals from third parties, (ii) defending any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the transactions contemplated hereby and thereby, and (iii)
executing and delivering such instruments, and taking such other actions as the
other party hereto may reasonably require in order to carry out the intent of
this Agreement.

                                  6..1.5 Credit Agreement.  The parties hereto

listed therein as Lenders, and Wells Fargo Bank, National Association, as

stock.

or (ii) any of its other officers and employees other than pursuant to

                          (i)     Tax Matters.  Greiner shall not make any tax

                          (l)     Agreement.  Neither Greiner nor any of the
Greiner Subsidiaries shall agree or commit to do any of the actions described
in this Section 6.2.1.

                          6.2.2 Stockholders' Meeting; Proxy Statement.
Greiner 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 Greiner's Board of Directors
(subject to the fiduciary obligations of its directors and officers).  Greiner
shall send to its stockholders, for the purpose of considering and voting upon
the Merger, a Proxy Statement satisfying all





                                      -26-
<PAGE>   165
requirements of applicable state and Federal laws, and Greiner shall be solely
responsible for any statement, information or omission in said Proxy Statement
relating to it or its affiliates.

                          6.2.3 Acquisition Proposals.  From the date hereof
until the earlier of the termination of this Agreement or the consummation of
the Merger, Greiner and the Greiner 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 Greiner, 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 Greiner
and its officers and directors, from responding to and considering unsolicited
firm offers for any such transaction from persons other than URS if and to the
extent that, in the written opinion of Greiner'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 Greiner's directors to Greiner's
stockholders.  Greiner 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 Greiner or any of its officers or
directors enters into any such negotiations or discussions for any reason which
thereby constitute a breach of this Section 6.2.3, Greiner shall immediately
reimburse URS for all expenses and costs incurred by URS in connection with the
transactions contemplated by this Agreement.  In the event that Greiner 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 Greiner, 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, Greiner shall pay to URS a
termination fee in the amount of $5.0 million (the "Termination Fee");
provided, however, that such Termination Fee shall not be payable if, prior to
the entry by Greiner into such letter of intent, understanding or other
agreement, URS has unilaterally declined to close the Merger.  The parties
acknowledge and agree that the expense reimbursement obligation and Termination
Fee described in this Section shall not be the exclusive remedy to URS in the
event of a breach by Greiner of this Agreement, and, in any such event, URS
shall be 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.

                          6.2.4  Maintenance of Business.  Greiner  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 Greiner becomes aware of a
deterioration in the relationship with any 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.  Greiner 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.

                 assuming due authorization, execution, delivery and
                 performance by each of the other parties hereto, constitutes
                 the valid and binding obligation of URS, enforceable in
                 accordance with its terms, except as such enforceability may
                 be limited by bankruptcy or other laws relating to or
                 affecting creditors' rights generally and by equitable
                 principles; and

Greiner agree that they will not issue any press release or otherwise make any

required by applicable law.





                                      -31-
<PAGE>   170
                 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.  Use of Name.  Without limiting the right of URS
to conduct its business in such manner as it deems appropriate, URS intends,
following the Closing Date, and for the foreseeable period thereafter, to
maintain Greiner as a separate subsidiary operating under its own existing
name.

                 Section 8..5.  Employee Matters.  After the Closing Date, URS
will use reasonable efforts to maintain the business of Greiner and, in
particular, without limitation, URS will use best efforts to maintain health,
medical, dental and other benefits for Greiner employees for a reasonable
period after the Closing Date which, in the aggregate, are reasonably
comparable to benefits provided to Greiner employees prior to the Closing Date,
subject to reasonable business practices and changing conditions.

                 Section 8..6.  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 hereto contained herein in the absence of fraud or
willful misconduct on the part of such stockholder, director, officer or
employee.

                 Section 8.7 The Performance Plan and Stock Ownership Plan of
Greiner Engineering, Inc.  URS, the Greiner Subsidiaries and Greiner agree that
as soon as practical following the execution of this Agreement, effective as of
the Closing Date and contingent on closing the Merger, The Performance Plan and
Employees Stock Ownership Plan of Greiner Engineering, Inc. (the "Plan") will
be amended to cease to be an employee stock ownership plan within the meaning
of Section 4975(e)(7) of the Code ("ESOP"), but will be continued as a profit
sharing plan, subject to the terms of the Plan document regarding amendment
and/or termination.  Such Plan amendment will provide that the cash proceeds
received by the Plan pursuant to this Agreement will not be reinvested in URS
or Greiner stock, but shall be reinvested in the various investment options
available under the non-ESOP portion of the Plan, as directed by Plan
Participants, and that employer stock will no longer be one of the investment
options offered under the Plan.  URS stock received pursuant to this Agreement
shall continue to be held by the Plan, subject to the investment discretion of
the Plan's trustee, but no additional investments in URS stock shall be
permitted, and, unless URS agrees otherwise, Plan Participants shall not have
investment discretion with respect to the URS stock so held.  In addition, in
the event that as of the Closing Date, the aggregate value of the unvested ESOP
portion of the Plan accounts shall be less than $1,000,000 (for purposes of
this Section 8.7, unvested shares of Greiner





                                      -32-
<PAGE>   171
stock shall be valued at an amount equal to the closing price of the Greiner
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), URS, the
Greiner Subsidiaries and Greiner agree that as soon as practical following the
execution of this Agreement, effective as of the Closing Date and contingent on
the closing of the Merger, the Plan will be amended so that Plan Participants
will be fully vested in the ESOP portion of their accounts as of the Closing
Date.  The parties shall cooperate and take all steps as may be reasonably
necessary to effect the foregoing.

                                   ARTICLE 9.

                                  TERMINATION

                 Section 9..1.  Termination.  This Agreement may be terminated
at any time prior to the Effective Time, whether before or after the approval
by the stockholders of Greiner (the "Stockholder Approval") has been obtained:

                          9..1.1 by mutual written consent of URS and Greiner;

                          9..1.2  by either Greiner or URS if (i) the
Stockholder Approval shall not be obtained by reason of stockholders holding a
majority of the Greiner Common Stock failing to vote in favor of approval of
this Agreement at a meeting of stockholders 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
September 30, 1996 (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 Greiner
of any representation, warranty, covenant or other agreement in this Agreement
which has a Greiner Material Adverse Effect, and such breach has not been
cured, or Greiner has not commenced reasonable efforts to cure such breach,
within thirty (30) days after written notice of such breach is given by URS to
Greiner;

                          9..1.4  By URS if Greiner 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 effect the rights of URS to reimbursement of expenses and the
Termination Fee as provided in Section 6.2.3; or

                          9..1.5  By Greiner 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 Greiner to URS.

                          9..1.6  By Greiner if any of the conditions set forth
in Section 7.1 hereof shall not have been fulfilled on or prior to the date
specified for fulfillment thereof, or shall have become impossible to fulfill
for reasons beyond the control of Greiner, and such condition shall not have
been waived.

                          9..1.7  By URS if any of the conditions set forth in
Section 7.2 hereof shall not have been fulfilled on or prior to the date
specified for fulfillment thereof, or shall have become impossible to





                                      -33-
<PAGE>   172
fulfill for reasons beyond the control of URS, and such condition shall not
have been waived.

Where action is taken to terminate this Agreement pursuant to this Section 9.1,
it shall be sufficient for such action to be authorized by the Board of
Directors of the party taking such action without any requirement to submit
such action to the stockholders of such party.

                 Section 9..2.  Effect of Termination and Abandonment.  In the
event of termination of the Agreement by either Greiner or URS as provided in
Section 9.1, this Agreement shall forthwith become void and have no effect, and
there shall be no liability or obligation on the part of Greiner, URS or the
Subsidiary, or their respective officers and directors, except that (i) the
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; provided, however, that in
the event such breach is the result of negligence, such damages shall not
exceed the sum of $500,000; but, provided, further, that in the event that such
breach is the result of recklessness or willful conduct, the amount of damages
shall not be limited hereby.

                 Section 9..3.  Amendment.  This Agreement may be amended by
the parties hereto, by action taken by their respective Boards of Directors at
any time before or after the approval of the stockholders of Greiner (the
"Stockholder Approval"), but after the Stockholder Approval, no amendment shall
be made which by law requires the further approval of stockholders without
obtaining such approval.  This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto.

                 Section 9..4.  Extension; Waiver.  At any time prior to the
Effective Time of the Merger, any party hereto, by action taken by its Board of
Directors may, to the extent legally allowed, (a) extend the time for the
performance of any of the obligations or other acts of the other parties
hereto, (b) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto and (c) waive
compliance with any of the agreements, covenants, or conditions for the benefit
of such party 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.


                                  ARTICLE 10.

                                 MISCELLANEOUS
