Item 1.   BUSINESS

General
- -------
     Jacobs Engineering Group Inc. (the "Company") is one of the largest
professional service firms in the United States providing engineering, design
and consulting services; construction and construction management services; and
process plant maintenance services to a broad range of industrial, commercial
and governmental clients.  The Company provides its services through offices and
subsidiaries located in the United States, Europe, India, Mexico and Chile.

     The Company focuses its services on selected industry groups and markets
including chemicals; petroleum; semiconductor; pulp and paper; pharmaceuticals
and biotechnology; federal programs; and buildings and infrastructure (this last
group includes transportation and health care projects, commercial and
governmental buildings, and other industrial projects).

     Over the past several years, the Company has grown its business through
both internal initiatives and strategic acquisitions.  The acquisitions have
allowed the Company to (i) expand or enhance the range of services it provides
its clients; (ii) expand its client base; and (iii) provide access to new
geographical areas.

     In Fiscal 1994, the Company acquired CRS Sirrine and CRSS Constructors
(whose principal offices are located primarily within the United States).  These
acquisitions greatly expanded the Company's professional staff.  They provided
broad-based skills in the pulp and paper market (which was a new market for the
Company at that time), and enhanced the Company's capabilities for its clients
in both the semiconductor and buildings and infrastructure markets.  These
acquisitions also strengthened the Company's capabilities in the area of
construction management services, expanded the Company's client base, and
provided increased resources in the southeast region of the United States.

     In Fiscal 1997, the Company acquired The Serete Group (headquartered in
Paris, France).  This acquisition provided the Company with an established
presence in France, Spain and Italy.  It added professional staff, and enhanced
the Company's existing engineering capabilities.  It also expanded the Company's
client base in several key market groups.  Also in Fiscal 1997, the Company
increased its ownership interest (such that the Company became the majority
owner) in Humphreys & Glasgow Consultants Limited (headquartered in Mumbai,
India).  This acquisition gave the Company access to the Southern Asia market,
expanded the Company's client base and added professional staff.  Also in Fiscal
1997, the Company acquired certain assets and contracts of an engineering
business specializing in the mining and minerals markets with offices in Denver,
Colorado and Santiago, Chile.

     In addition to the particular advantages described above, these
acquisitions have allowed the Company to grow its relationships with its major
clients.  By expanding into new geographical areas, and by adding to its
existing technical and project management capabilities, the Company strives to
position itself as a preferred, single-source provider of professional
engineering and construction services to its major clients.

     In December 1998, the Company signed an agreement and plan of merger with
the Sverdrup Corporation ("Sverdrup").  If and when the transaction is
completed, Sverdrup Corporation will become a wholly-owned subsidiary of the
Company.  Sverdrup is one of the largest professional service firms in the
United States engaged in engineering, architecture, construction and
construction management, and scientific services.  Sverdrup employs more than
5,500 people located in more than 30 offices primarily within the United States.
Sverdrup provides its services to clients in three broad business areas:  civil
engineering and construction (e.g., providing design and construction services
for wastewater treatment plants, and roads, bridges, railroads and other
transportation facilities); the facilities market (e.g., providing 

                                     Page 1
<PAGE>
 
design, construction management and program management services on projects for
educational facilities, correctional facilities, and other government and
commercial buildings and programs); and advanced technology (e.g., providing a
wide-range of services, including operations and maintenance services, to
government and private clients for testing facilities, research centers, and
other high-technology facilities). The merger is expected to be completed early
in the second quarter of fiscal 1999.

     The Company is a Delaware corporation and was originally incorporated in
1957 as a successor to a business organized by Dr. Joseph J. Jacobs in 1947.
The Company's common stock has been publicly held since 1970 and is currently
listed on the New York Stock Exchange.


Services Provided
- -----------------
     The Company offers three broad categories of professional services:
engineering (which includes design, consulting and other related services);
construction and construction management; and plant maintenance.  The Company
will often establish a relationship with a client where it is awarded a contract
for the initial phases of an engineering and/or construction project.  These
services may include feasibility studies, consulting or design work.  Because of
the range of technical expertise the Company possesses, it is often retained for
additional work as the project develops.  The scope of services provided by the
Company, therefore, ranges from consulting to complete single-responsibility
contracts.

     The following table sets forth the total revenues of the Company from each
of its three basic service categories for each of the five years ended September
30, 1998 (in thousands of dollars):

                           ==========   ==========   ==========   ==========   ==========
</TABLE>

Engineering
- -----------
     The Company employs all of the engineering and related disciplines needed
to engineer and design modern process plants (including projects for clients in
the chemicals, pharmaceuticals and biotechnology, petroleum, food, and minerals
and fertilizers industries), semiconductor facilities, pulp and paper plants,
and other facilities (such as high technology manufacturing operations and other
specialized plants).

     With respect to the Federal Programs area of the Company's business (a
substantial portion of which involve environmental projects), the Company
employs all of the requisite engineering, scientific, public health and related
skills to consult, investigate, study, manage and provide remedial engineering
for major environmental programs.  The Company's capabilities in process
engineering and construction combined with its environmental expertise allow it
to offer its clients a wide range of services as a single-source provider.
Accordingly, the Company has been awarded contracts requiring a combination of
traditional process engineering and environmental services.

     The Company also employs all of the professional and technical expertise
necessary to provide a broad range of consulting services including:  performing
pricing studies, market analyses and financial projections necessary in
determining the feasibility of a project; performing gasoline reformulation
modeling; analyzing and evaluating layout and mechanical designs for complex
processing plants; analyzing automation and control systems; analyzing,
designing and executing biocontainment strategies; developing and performing
process protocols in respect of Federal Drug Administration mandated
qualification/validation requirements; and performing geological and
metallurgical studies.

                                     Page 2
<PAGE>
 
     Also included in the category of "Engineering" are all of the related
support services necessary for the proper and effective delivery of the
Company's engineering and related services.  Among these are cost engineering,
planning, scheduling, procurement, estimating, project accounting, quality and
safety.

     Construction
     ------------
     The Company provides traditional field construction as well as construction
management services to private and public sector clients in virtually all of the
industries to which it provides engineering services.  The Company can also
provide its clients with Advanced Construction Technology ("ACT")(R).  ACT is an
advanced form of off-site engineering, design, fabrication and assembly, and
field erection.  ACT provides clients with an alternative approach to
traditional methods of engineering and construction which can compress and
shorten the construction schedule, as well as help to reduce costs.  In the
environmental area, recent contract awards from clients in the public sector
require the Company to provide environmental remedial construction services.

     Historically, the Company's field construction activities have been focused
primarily on those construction projects for which the Company performed the
related engineering and design work.  By focusing its construction efforts on
such projects, the Company seeks to avoid the risk of constructing complex
plants based on designs prepared by others.  The financial risk to the Company
of constructing complex plants based on designs prepared by third parties may be
particularly significant on fixed-price contracts.

     The Company actively markets all of its services to clients on projects
where the scope of services required is within the Company's fields of
expertise.  The Company believes that by integrating and bundling its services
(i.e., providing design, engineering and construction services on the same
project) it can price its services more competitively and can enhance the
overall contract profitability.  The Company also believes that clients benefit
from such an approach because they can look to the Company as a single-source
provider of design/build services.  However, the Company will continue to pursue
construction-only projects where it can negotiate pricing and other contract
terms acceptable to the Company.

     In the area of construction management, the Company can provide a wide
range of services to its clients.  The Company may act as the program director,
whereby it oversees, on behalf of the owner of the project, the complete
planning, design and construction phases of the project.  Or, its services may
be limited to providing construction consulting, estimating, scheduling or value
engineering services.

     Maintenance
     -----------
     Maintenance generally refers to all of the tasks required to keep a plant
in day-to-day operation, including the repair and replacement of pumps, piping,
heat exchangers and other equipment.  It also includes "turnaround" work which
involves major refurbishment which can only be performed when the plant is shut
down.  Since shutdowns are expensive to the owners of the plant, turnaround work
will often require maximizing the number of skilled craft personnel that can
work efficiently on a project on a 24 hours per day, seven days per week basis.
The Company employs sophisticated computer scheduling and programming to
complete turnaround projects quickly and it maintains contact with a large pool
of skilled craftsmen it can hire as needed on maintenance and turnaround
projects.

     Although the profit margins that can be realized from maintenance services
are generally lower than those associated with the other services the Company
provides, the costs to support maintenance activities are also generally lower
than those associated with the Company's other services.  Furthermore, since
maintenance contracts are normally cost-reimbursable in nature, they present
less risk to the Company.  Additionally, although engineering and construction
projects may be of a short-term nature, maintenance services often result in
long-term relationships with clients.  For example, the Company has been
providing maintenance services at several major process plants for over 30
years.  This aspect of maintenance services greatly reduces the selling costs in
respect of such services.

                                     Page 3

Industry Groups and Markets
- ---------------------------
     The Company focuses its efforts on the following industry groups and
markets: chemicals; buildings and infrastructure; petroleum; pharmaceuticals and
biotechnology; pulp and paper; U.S. federal programs; and semiconductor.  The
Company believes these industry groups and markets have sufficient common needs
to permit cross-utilization of the Company's resources which help to mitigate
the negative effects of a downturn in a single industry.

     The following table sets forth the total revenues of the Company from each
of these industry groups and markets for each of the five years ended September
30, 1998 (in thousands of dollars):

                        ==========   ==========   ==========   ==========   ==========
</TABLE>

     Chemicals
     ---------
     The Company has always considered the chemicals industry a cornerstone of
its business.  Revenues from this industry group have consistently accounted for
a significant share of each year's total revenues.  Historically, whenever the
Company has sought to expand its business, the impact of such expansion on the
Company's chemicals business has always been an important consideration.  The
Company's first office outside the United States was opened in support of a
bulk-chemical project for a large, U.S. company seeking to expand its operations
internationally.

     Currently, the Company furnishes its full line of services to its clients
operating in the chemicals industries.  The Company has provided technical,
financial, marketing and management consulting services to many of the largest
chemical manufacturers in the world.  The Company can perform feasibility
studies, as well as preliminary and detailed design and engineering services,
construction, and construction management services to its clients in this
industry.  Typical projects range from various basic and intermediate chemical
reactions/separations and high-pressure polymer processes for the production of
bulk chemicals, to low-pressure, multi-product processes for the production of
fine and specialty chemicals.  The Company has also completed projects dealing
with the modernization and upgrading of polyethelene and liquid polymer
production facilities.  The Company has extensive knowledge of, and experience
with, advanced polymerization reactions and state-of-the-art, post-reactor
processing techniques, as well as many other specialty chemicals.

     A significant aspect of the Company's service to this industry is in the
area of contract maintenance.  The Company has contracts with several major
chemical producers to provide on-site maintenance and turnaround activities.
Many of these contracts are evergreen in nature and tend to be extended over
many years.

     Another important aspect of this industry group has been the development of
performance-based partnering relationships (alliances) with clients.  Through an
alliance, a client will award a contract to the Company which can require the
Company to provide a broad scope of services.  These services can range from the
Company providing on-site engineering services for projects or tasks as they
arise or are defined by the client, to situations where the Company is assigned
to manage and complete an entire program of capital improvements for the client.
Although alliances typically begin with the Company 

                                     Page 4
<PAGE>
 
providing engineering services for small capital projects, alliances can
sometimes provide the Company with opportunities to expand its services to
include fully-integrated engineering, procurement, construction and construction
management services.

     Buildings and Infrastructure
     ----------------------------
     Buildings and infrastructure refers to those contracts requiring the
Company to provide and/or manage comprehensive architectural, engineering,
design, construction and/or construction management services for projects such
as high technology manufacturing operations, specialized plants for clients in
the food industry, and research and development facilities that require
technically complex structures.  It also includes programming, design, program
management and construction management services for public, institutional and
corporate clients.

     The Company provides its services on projects that emphasize both new
construction as well as those involving renovation and refurbishment of existing
facilities.  The Company has also been successful in applying its skill base to
clients requiring complete program management (referred to as "resourcing").
For such contracts, the Company, often through joint ventures with third
parties, assume full responsibility for the ongoing operations and maintenance
of entire commercial or industrial complexes on behalf of the client.

     Typical projects in this area include educational facilities, civic
centers, health care facilities, correctional centers and transportation
systems, as well as multi-purpose buildings for industrial, commercial and
government clients.

     Petroleum
     ---------
     The Company provides its full line of services to its clients in the
petroleum industry.  Typical projects in the petroleum area include retrofits,
revamps or expansions of existing plants, upgrading individual process units
within refineries, new construction and maintenance services.  The Company also
provides a broad range of consulting services to its clients, including process
assessments, feasibility studies, technology evaluations and multi-client
studies.  Although the Company's revenues historically have related primarily to
projects associated with petroleum refining and the processes and technologies
required for the conversion of crude oil and gas into petroleum fuels, chemical
feedstocks and lubricants, more recent contract awards have also included
services to pipeline companies and companies in businesses upstream of refiners.

     The volume of business activity in this industry group is sometimes
influenced by government regulations.  For example, as the government issues
regulations requiring the reduction of the sulfur content of motor fuels,
capital spending by clients for desulfurization projects have increased.  There
are also significant levels of economically-driven work associated with
reconfiguring refineries to handle increasing levels of imported, heavy sour
crude feedstocks.  The Company is actively involved in both such government and
economically-driven projects.

     The Company has also utilized its off-site construction capabilities on a
number of projects in the petroleum industry.  Due to the age of many U.S.
refineries, and the close proximity within these refineries of their various
production and distillation processing units, the Company believes the use of
off-site construction can help decongest the construction site and allow for
parallel construction to proceed simultaneously with the modular activity.

     Like the chemicals industry, the Company provides a significant amount of
maintenance services to its clients in the petroleum industry.  Also like the
chemicals industry, the Company has established a number of formal alliances
with various clients in the petroleum industry.  Some of these alliances have
been national in scope.

     Pharmaceuticals and Biotechnology
     ---------------------------------
     The Company furnishes its full line of services to its clients operating in
the pharmaceuticals and biotechnology industries.  The scope of services the
Company can provide its clients in these markets include feasibility studies,
preliminary and detailed design and engineering services, construction, and
construction management services.  The Company can also provide conceptual
design services with emphasis on production strategy, current good manufacturing
practices ("cGMP") compliance, regulatory compliance and
qualification/validation services for pharmaceutical and biotechnology research,
development and production facilities.  Accordingly, the Company is fully
capable of executing multi-million dollar, single-responsibility projects in the
areas of pharmaceuticals and biotechnology.

     Typical projects for clients in this industry include laboratories and
research and development facilities, vivariums, pilot plants, chemical
production facilities, full-scale biotechnology production facilities, and fill-
and-finish facilities.  These projects will often employ state-of-the-art know-
how in regulatory, barrier technology, and micro-environmental systems, as well
as automation, manufacturing and distribution management.

     The Company has also established formal alliances with various clients in
the pharmaceuticals industry.

     Pulp and Paper
     --------------
     The Company provides a broad range of engineering and construction services
to its clients in the pulp and paper industry.  Additionally, the Company
provides strategic planning and conceptual studies for many of its clients, as
well as environmental services relating to compliance with USEPA emission
standards.  Typical projects in the pulp and paper area range from small mill
projects to complex, multi-million dollar paper machine rebuilds, mill
expansions and construction of new facilities.  Such projects encompass all
areas of a mill, including woodyards, pulping and bleaching, papermaking,
chemical recovery, material handling and power and steam generation.  In the
area of papermaking, the Company's expertise includes tissue and towel, coated
and uncoated fine papers, newsprint and linerboard.  The Company's expertise
also includes the converting and packaging of paper products for consumer use.
The Company has been instrumental in the design and installation of state-of-
the-art facilities for recycle fiber, deinking and pulp bleaching.  Chemical
recovery and power generation are an integral part of the papermaking process.
The Company has broad experience in these areas and has applied its expertise in
the engineering and construction of such facilities for the pulp and paper
industry.

     The Company has also established formal alliances with various clients in
the pulp and paper industry.

     Federal Programs
     ----------------
     A significant portion of the Company's Federal Programs revenues are
derived from environmental projects.  The Company believes it is one of the
leading providers of environmental restoration, engineering and consulting
services, including hazardous waste management and site cleanup and closure in
the United States.  Many of the projects for the U.S. government span several
years.  For larger programs, the scope of services is such that the Company
sometimes teams with other companies in order to execute the project.  The
Company is currently providing environmental restoration, engineering,
construction and site operations and maintenance services for a number of U.S.
federal government agencies including the U.S. Department of Energy ("DOE"), the
Department of Defense ("DOD") and the U.S. Environmental Protection Agency
("USEPA").

     Historically, typical projects for U.S. government agencies included the
preparation of feasibility studies and performance of remedial investigations,
engineering, design and remediation services on several national programs.  Many
of the Company's contracts related to the Comprehensive Environmental Response
Compensation and Liability Act of 1980 ("CERCLA" or "Superfund") and the related
Superfund Amendments and Reauthorization Act of 1986 ("SARA"), as reauthorized
in 1990.

                                     Page 6
<PAGE>
 
     More recently, as government spending has shifted from studying
environmental problems to cleaning-up contaminated sites, the Company has been
awarded multi-year contracts to provide such services.  For example, the Company
was awarded a contract from the U.S. Air Force to provide full-service remedial
action services for the U.S. Air Force Center for Environmental Excellence
("AFCEE") at several bases located in the U.S., as well as a "nationwide" award
to provide services under the U.S. Base Realignment and Closure ("BRAC")
program.  And in 1995, the Company was awarded the Alaska TERC (Total
Environmental Restoration Contract) to provide engineering and site cleanup
services throughout that state.

     Demand for the Company's services in this area is strongly affected by the
level of enforcement of environmental laws and regulations, and the spending
patterns of public and private clients.  Currently, there are numerous proposals
being offered for consideration to overhaul the U.S. federal regulatory process,
the ultimate outcome of which cannot yet be determined.  Nevertheless, the
Company believes that the DOE and DOD will continue to devote increasingly more
of their resources to site remediation and cleanup.

     In addition to contracts involving the remediation of contaminated sites,
the government has let contracts to private contractors to provide full
operations and maintenance ("O&M") services to entire government facilities.
The Company has been awarded several such O&M contracts, which require the
Company to provide facilities management and maintenance services, utilities
operations and maintenance services, property management and disposition and
construction support services.  The Company believes it is uniquely qualified to
execute O&M contracts given its financial strength, and the history the Company
has of managing large, long-term projects in both the private and government
sectors of the economy.

     Semiconductor
     -------------
     The Company provides engineering, procurement, construction, and
construction management services to its clients in the semiconductor industry.
Typical projects in this industry range from on-site plant engineering and tool
hook-ups, to multi-million dollar state-of-the-art wafer fabrication and crystal
growing facilities used to produce microprocessors for computers and other
consumer electronic devices.  Generally, projects in the semiconductor industry
are more complex than other facilities projects and have greater emphasis on
cleanroom, and similar high-end technologies.


Backlog

     For information regarding the Company's backlog, reference should be made
to Item 7. - Management's Discussion and Analysis of Financial Condition and
Results of Operations, incorporated by reference in this report.


Customers
- ---------
     For the years ended September 30, 1994, 1995, 1996, 1997 and 1998, revenues
directly or indirectly from agencies of the U.S. federal government accounted
for 15.4%, 11.4%, 8.7%, 12.0% and 12.1%, respectively, of total revenues.  Due
to the amount of pass-through costs (see "Contracts" below) that may be incurred
on construction and maintenance projects, it is not unusual for a client in the
private sector to account for more than 10% of revenues in any given year.  One
client in the private sector accounted for 11.6% and 13.1% of total revenues in
1994 and 1995, respectively.  A different client accounted for 15.3% of total
revenues in 1997.  No single client in the private sector accounted for 10% or
more of total revenues in 1996 or 1998.

Foreign Operations
- ------------------
     For the years ended September 30, 1994, 1995, 1996, 1997 and 1998, revenues
from the Company's international operations were approximately 5.6%, 5.4%,
10.3%, 23.5% and 20.2%, respectively, of total revenues.  For fiscal years 1994
through 1996, substantially all such revenues related to the Company's offices
in the U.K. and Ireland.  In 1997, as discussed above, the Company completed the
acquisitions of the Serete Group and HGC India.  The Serete Group has operations
throughout Europe, and executes projects for commercial clients in the
chemicals, pharmaceuticals and semiconductor industries, as well as buildings
and infrastructure projects for both commercial and governmental clients.  HGC
India has operations in India and executes projects for commercial clients in
the chemical, pharmaceuticals and petroleum markets.  Revenues earned in fiscal
1997 and 1998 from the Company's offices in Mexico and Chile were not material.

Contracts
- ---------
     While there is considerable variation in the pricing provisions of the
contracts undertaken by the Company, they can generally be grouped into three
broad categories:  Cost-reimbursable; fixed-price and guaranteed maximum price.
The following table sets forth the percentages of total revenues represented by
these types of contracts during each of the five years ended September 30, 1998:

                                   1994    1995    1996    1997    1998
                                   -----   -----   -----   -----   -----
     Cost-reimbursable               83%     88%     82%     82%     81%
     Fixed-price                      9      11      16      16      18
     Guaranteed maximum price         8       1       2       2       1
 
     In accordance with industry practice, most of the Company's contracts are
subject to termination at the discretion of the client.  Contracts typically
provide for reimbursement of costs incurred and payment of fees earned through
the date of such termination.

     When the Company is directly responsible for engineering, design,
procurement and construction of a project or the maintenance of a process plant,
the Company reflects the cost of materials, equipment and subcontracts in both
revenues and costs.  On other projects, where the client elects to pay for such
items directly, these amounts are not reflected in either revenues or costs.
The following table presents the approximate amount of such pass-through costs
included in revenues for the years ended September 30, 1994, 1995, 1996, 1997
and 1998 (in millions):

              1994          1995           1996          1997         1998
              ----          ----           ----          ----         ----
            $ 629.0      $ 1,001.3      $ 1,019.5      $ 919.6      $ 1,066.4


     Cost-reimbursable contracts
     ---------------------------
     Cost-reimbursable contracts provide for reimbursement of costs incurred by
the Company plus a predetermined fee, or a fee based on a percentage of the
costs incurred.  The Company prefers this type of contract since it believes
that the primary basis for its selection should be its technical expertise and
professional qualifications rather than price considerations.

     Fixed-price contracts
     ---------------------
     Fixed-price contracts include both "negotiated fixed-price" contracts and
"lump sum bid" contracts.  Under a negotiated fixed-price contract, the Company
is first selected as the contractor, and then the contract price is negotiated.
Negotiated fixed-price contracts frequently exist in single-responsibility
arrangements where the Company has the opportunity to perform engineering and
design work before negotiating the total price of the project.  Under lump sum
bid contracts, the Company must bid against other contractors based upon
specifications furnished by the client.  This type of pricing presents certain
inherent risks, including the possibility of ambiguities in the specifications,
problems with new technologies 

                                     Page 8
<PAGE>
 
and economic and other changes that may occur over the contract period, that are
reduced by the negotiation process. Thus, although both types of contracts
involve a firm price for the client, the lump sum bid contract provides the
greater degree of risk to the Company. However, because of economies that may be
realized during the contract term, both negotiated fixed-price and lump sum bid
contracts may offer greater profit potential than the other types of contracts.

     Guaranteed maximum price contracts
     ----------------------------------
     Guaranteed maximum price contracts are performed in the same manner as
cost-reimbursable contracts; however, the total actual cost plus the fee cannot
exceed the guaranteed price negotiated with the client.  If the total actual
cost of the contract exceeds the guaranteed maximum price, then the Company will
bear all or a portion of the excess.  In those cases where the total actual cost
and fee are less than the guaranteed price, the Company will often share the
savings on a predetermined basis with the client.

Competition
- -----------
     The Company is engaged in a highly competitive business.  Some of its
competitors are larger than the Company, or are subsidiaries of larger
companies, and may possess greater resources than the Company.  Furthermore,
because the engineering aspect of the business does not usually require large
amounts of capital, there is relative ease of market entry for a new potential
entrant possessing acceptable professional qualifications.  Accordingly, the
Company competes with both national and international firms in sizes ranging
from very large to a wide variety of small, regional and specialty firms.

     The extent of the Company's competition varies according to the industries
and markets it serves, as well as the geographical areas in which the Company
operates.  The Company's largest competitors for engineering, construction and
maintenance services for process plants include such well-known companies as
Bechtel Group, Inc., Fluor Corporation, Foster-Wheeler Corp., Raytheon
Engineers, M.W. Kellogg, Parsons Co., Kellogg Brown & Root, and Kvaerner.  In
the semiconductor industry, the Company's principal competitors include
Industrial Design Corporation.  In the area of pulp and paper, the Company's
principal competitors include BE&K, Kellogg Brown & Root, and Raytheon
Engineers.  And in the area of environmental engineering and hazardous waste
cleanup, the Company's principal competitors include many of the companies
listed above, as well as Morrison Knudsen Corporation, and other specialized
companies such as IT Group, Inc., ICF Kaiser and Roy F. Weston.

Employees
- ---------
     At September 30, 1998, the Company had approximately 10,080 full-time
employees.  Additionally, as of September 30, 1998, there were approximately
7,160 persons employed by the Company in the field on a project basis.  The
number of such field employees varies in relation to the number and size of the
maintenance and construction projects in progress at any particular time.

Item 3.   LEGAL PROCEEDINGS

     In the normal course of business, the Company is subject to certain
contractual guarantees and litigation.  Generally, such guarantees relate to
project schedules and plant performance.  Most of the litigation involves the
Company as a defendant in workers' compensation, personal injury and other
similar lawsuits.  In addition, as a contractor for many agencies of the United
States Government, the Company is subject to many levels of audits,
investigations and claims by, or on behalf of, the government with respect to
its contract performance, pricing, costs, cost allocations and procurement
practices.

     Management believes, after consultation with counsel, that such guarantees,
litigation, and United States Government contract-related audits, investigations
and claims should not have any material adverse effect on the Company's
consolidated financial statements.

     In March 1998, the U.S. Attorney for the Central District of California
announced that it was intervening in a lawsuit filed against the Company by a
former employee under the False Claims Act.  The lawsuit alleges that the
Company overbilled the U.S. government for lease costs paid by the Company and
relating to its former headquarters building located in Pasadena, California.
The building had once been owned by the Company, but was sold by it in calendar
1982, at which time the Company entered into a 15-year lease of the property.
The lawsuit seeks unspecified damages against the Company, which may be trebled
under certain provisions of the Act.  Additional remedies available to the
government include possible administrative or civil liabilities, and the
imposition of civil penalties for each violation.

     The Company has denied any wrongdoing in the method it accounted for the
lease costs in question.  The Company contends it has billed the government for
only those costs it actually incurred, and believes its accounting treatment of
the lease costs complied with all applicable regulations.  Furthermore, the sale
and lease-back transaction that is the subject of the lawsuit occurred nearly 15
years prior to the initiation by the Department of Justice of its investigation.
The transaction had been fully disclosed in numerous public filings made by the
Company since the date of the transaction, and the Company's Final Indirect Cost
Rate Proposals, which the Company had filed regularly and routinely with the
Defense Contract Audit Agency ("DCAA") and which included the lease costs, had
been audited by the DCAA for many years without the DCAA taking exception to the
Company's accounting treatment of the lease costs.

     Although the final outcome of this matter cannot be determined at the
present time, the Company intends to vigorously defend itself against the
lawsuit.

                                  UNDERTAKINGS

     For the purposes of complying with the amendments to the rules governing
Form S-8 (effective July 13, 1990) under the Securities Act of 1933, the
undersigned Registrant hereby undertakes as follows, which undertaking shall be
incorporated by reference into the Registrant's Registration Statements on Form
S-8 Nos. 33-45914 (filed February 21, 1992) and 333-01317 (filed February 29,
1996):

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by final adjudication of such issue.

In order that the Corporation may determine the stockholders entitled to notice

     of or to vote at a meeting of stockholders shall be at the close of

     day on which the meeting is held.

          (ii)   The record date for determining stockholders for any other
     purpose shall be at the day on which the first written consent is
     expressed.

          (iii)  The record date for determining stockholders for any other

     adopts the resolution relating thereto.

     A determination of stockholders of record entitled to notice of or to vote

vote in the election of Directors at the meeting who complies with the notice
procedures set forth in this Section 2.06.  Such nominations, other than those
made by or at the direction of the Board, shall be made pursuant to timely
notice in writing to the Secretary of the Corporation.  To be timely, a
stockholder's notice shall be delivered to or mailed and received at the
principal executive offices of the Corporation not less than 60 days nor more
than 90 days prior to the meeting; provided, however, that in the event that
less than 70 days' notice or prior public disclosure of the date of the meeting
is given or made to stockholders, notice by the stockholder to be timely must be
so received not later than the close of business on the 10th day following the
day on which such notice of the date of the meeting was mailed or such public
disclosure was made.  Such stockholder's notice shall set forth (a) as to each
person whom the stockholder proposed to nominate for election or re-election a
Director, (i) the name, age, business address and residence address of such
person, (ii) the principal occupation or employment of such person, (iii) the
class and number of shares of the Corporation which are beneficially owned by
such person and (iv) any other information relating to such person that is
required to be disclosed in solicitations of proxies for election of Directors,
or is otherwise required, in each case pursuant to Regulation 14A under the
Securities Exchange Act of 1934, as amended (including without limitation such
persons' written consent to being named in the proxy statement, if any, as a
nominee and to serving as a Director if elected); and (b) as to the stockholder
giving the notice (i) the name and address, as they appear on the Corporation's
books, of such stockholder and (ii) the class and number of shares of the
Corporation that are beneficially owned by such stockholder.  At the request of
the Board any person nominated by the Board for election as a Director shall
furnish to the Secretary of the Corporation that information required to be set
forth in a stockholder's notice of nomination which pertains to the nominee.  No
person shall be eligible for election as a Director of the Corporation unless
nominated in accordance with the procedures set forth in this Section 2.06.  The
Chairman of the meeting shall, if the facts warrant, determine and declare to
the meeting that a nomination was not made in accordance with the procedures
prescribed by the bylaws, and if he should so determine, he shall so declare to
the meeting and the defective nomination shall be disregarded.

     SECTION 2.07 QUORUM.  Except in the case of any meeting for the election of
directors summarily ordered as provided by law, the holders of record of a
majority in voting interest of the shares of stock of the Corporation entitled
to be voted thereat, present in person or by proxy, shall constitute a quorum
for the transaction of business at any meeting of the stockholders of the
Corporation or any adjournment thereof.  In the absence of a quorum at any
meeting or any adjournment thereof, a majority in voting interest of the
stockholders present in person or by proxy and entitled to vote thereat or, in
the absence therefrom of all the stockholders, any officer entitled to preside
at, or to act as secretary of, such meeting may adjourn such meeting from time
to time.  At any such adjourned meeting at which a quorum is present any
business may be transacted that might have been transacted at the meeting as
originally called.

     SECTION 2.08 VOTING.

     (a)  Each stockholder shall, at each meeting of the stockholders, be
entitled to vote in person or by proxy each share or fractional share of the
stock of the Corporation that has voting rights on the matter in question and
that has been held by him and registered in his name on the books of the
Corporation:

          (i)  on the date fixed pursuant to Section 6.05 of these Bylaws as the
     record date for the determination of stockholders entitled to notice of and
     to vote at such meeting, or

          (ii) if no such record date shall have been so fixed, then (a) at the
     close of business on the day next preceding the day on which notice of the
     meeting shall be given or (b) if notice of the meeting shall be waived, at
     the close of business on the day next preceding the day on which the
     meeting shall be held.

     (b)  Shares of its own stock belonging to the Corporation or to another
corporation, if a majority of the shares entitled to vote in the election of
directors in such other corporation is held, directly or indirectly, by the
Corporation, shall neither be entitled to vote nor be counted for quorum
purposes.  Persons holding stock of the Corporation in a fiduciary capacity
shall be entitled to vote such stock.  Persons whose stock is pledged shall be
entitled to vote, unless in the transfer by the pledgor on the books of the
Corporation he shall have expressly empowered the pledgee to vote thereon, in
which case only the pledgee, or his proxy, may represent such stock and vote
thereon.  Stock having voting power standing of record in the names of two or
more persons, whether fiduciaries, members of a partnership, joint tenants,
tenants in common, tenants by the entirety or otherwise, or with respect to
which two or more persons have the same fiduciary relationship, shall be voted
in accordance with the provisions of the General Corporation Law of the State of
Delaware.

     (c)  Any such voting rights may be exercised by the stockholder entitled
thereto in person or by his proxy appointed by an instrument in writing,
subscribed by such stockholder or by his attorney thereunto authorized and
delivered to the secretary of the meeting; provided, however, that no proxy
shall be voted or acted upon after three years from its date unless said proxy
shall

                                       4
<PAGE>
 
provide for a longer period.  The attendance at any meeting of a stockholder who
may theretofore have given a proxy shall not have the effect of revoking the
same unless he shall in writing so notify the secretary of the meeting prior to
the voting of the proxy.  At any meeting of the stockholders all matters, except
as otherwise provided by the Certificate of Incorporation, in these Bylaws or by
law, shall be decided by the vote of a majority of the shares present in person
or by proxy and entitled to vote thereat and thereon, a quorum being present.
The vote at any meetings of the stockholders on any question need not be by
ballot, unless so directed by the chairman of the meeting.  On a vote by ballot
each ballot shall be signed by the stockholder voting, or by his proxy, if there
be such proxy, and it shall state the number of shares voted.

     SECTION 2.09 LIST OF STOCKHOLDERS.  The Secretary of the Corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder for any purpose germane to the meeting
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the duration
thereof, and may be inspected by any stockholder who is present.  Such list
shall presumptively determine the identity of the stockholders entitled to
notice of and to vote at the meeting and the number of shares held by each of
them.

     SECTION 2.10 JUDGES.  If at any meeting of the stockholders a vote by
written ballot shall be taken on any question, the chairman of such meeting may
appoint a judge or judges to act with respect to such vote.  Each judge so
appointed shall first subscribe an oath faithfully to execute the duties of a
judge at such meeting with strict impartiality and according to the best of his
ability.  Such judges shall decide upon the qualification of the voters and
shall report the number of shares represented at the meeting and entitled to
vote on such question, shall conduct and accept the votes, and, when the voting
is completed, shall ascertain and report the number of shares voted respectively
for and against the question.  Reports of judges shall be in writing and
subscribed and delivered by them to the Secretary of the Corporation.  The
judges need not be stockholders of the Corporation, and any officer of the
Corporation may be a judge on any question other than a vote for or against a
proposal in which he shall have a material interest.

     SECTION 2.11 ACTION WITHOUT A MEETING NOT PERMITTED.  No action shall be
taken by the stockholders except at an annual or special meeting of
stockholders.  The power of the stockholders to consent in writing without a
meeting to the taking of any action is specifically denied.

     SECTION 2.12 CONDUCT OF MEETINGS OF STOCKHOLDERS.  Subject to the
following, meetings of stockholders generally shall follow accepted rules of
parliamentary procedure.

                                       5
<PAGE>
 
     (a)  The chairman of the meeting shall have absolute authority over matters
of procedure and there shall be no appeal from the ruling of the chairman.  If
the chairman, in his absolute discretion, deems it advisable to dispense with
the rules of parliamentary procedure as to any one meeting of stockholders or
part thereof, the chairman shall so state and shall clearly state the rules
under which the meeting or appropriate part thereof shall be conducted.

     (b)  If disorder should arise that prevents continuation of the legitimate
business of the meeting, the chairman may quit the chair and announce the
adjournment of the meeting; and, upon his so doing, the meeting shall be
immediately adjourned.

     (c)  The chairman may ask or require that anyone not a bona fide
stockholder or proxy leave the meeting.

     (d)  A resolution or motion shall be considered for vote only if proposed
by a stockholder or duly authorized proxy and seconded by an individual who is a
stockholder or a duly authorized proxy, other than the individual who proposed
the resolution or motion.

including any provisions for cumulative voting.

     SECTION 3.04 RESIGNATIONS.  Any director of the Corporation may resign at
any time by giving written notice to the Board or to the Secretary of the
Corporation.  Any such resignation shall take effect at the time specified

its receipt; and unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

     SECTION 3.05 VACANCIES.  Except as otherwise provided in the Certificate of
Incorporation, any vacancy in the Board, whether because of death, resignation,
disqualification, an increase in the number of directors, or any other cause,

such place or places within or without the State of Delaware as the Board may
from time to time by resolution designate or as shall be designated by the

any such meeting.  Directors may participate in any regular or special meeting

equipment pursuant to which all persons participating in the meeting of the
Board can hear each other, and such participation shall constitute presence in

     SECTION 3.09 SPECIAL MEETINGS.  Special meetings of the Board may be called
by the Chairman of the Board of Directors or the President and shall be called
by the President or Secretary on the written request of two directors.  Notice
of all special meetings of the Board shall be given to each director at such

                                       7
<PAGE>
 
     Such notice may be waived by any director and any meeting shall be a legal
meeting without notice having been given if all the directors shall be present
thereat or if those not present shall, either before or after the meeting, sign
a written waiver of notice of, or a consent to, such meeting or shall after the
meeting sign the approval of the minutes thereof. All such waivers, consents or
approvals shall be filed with the corporate records or be made a part of the

constitute a quorum for the transaction of business at any meeting of the Board.
Except as otherwise provided in the Certificate of Incorporation or these Bylaws
or by law, all matters shall be decided at any such meeting, a quorum being
present, by the affirmative votes of a majority of the directors present.  In
the absence of a quorum, a majority of directors present at any meeting may
adjourn the same from time to time until a quorum shall be present.  Notice of
any adjourned meeting need not be given.  The directors shall act only as a
Board, and the individual directors shall have no power as such.

     SECTION 3.11 ACTION BY CONSENT.  Any action required or permitted to be
taken at any meeting of the Board or of any committee thereof may be taken
without a meeting if a written consent thereto is signed by all members of the
Board or of such committee, as the case may be, and such written consent is
filed with the minutes of proceedings of the Board or committee.

     SECTION 3.12 MANIFESTATION OF DISSENT.  A director of the Corporation who

taken shall be presumed to have assented to the action taken unless his dissent
shall be entered in the minutes of the meeting or unless he shall file his
written dissent to such action with the person acting as the secretary of the
meeting before the adjournment thereof or shall forward such dissent by
registered mail to the Secretary of the Corporation immediately after the
adjournment of the meeting.  Such right to dissent shall not apply to a director
who voted in favor of such action.

     SECTION 3.13 COMPENSATION.  The directors shall receive only such
compensation for their services as directors as may be allowed by resolution of
the Board.  The Board may also provide that the Corporation shall reimburse each
such director for any expense incurred by him on account of his attendance at
any meetings of the Board or Committees of the Board.  Neither the payment of
such compensation nor the reimbursement of such expenses shall be construed to
preclude any director from serving the Corporation or its subsidiaries in any
other capacity and receiving compensation therefor.

three or more directors appointed by the Board, who may meet at stated times, or
on notice to all members of such Committee by any of their own number, during

<PAGE>
 
meetings of the Board; they shall advise and aid the officers of the Corporation
in all matters concerning its interests and the management of its business, and
generally perform such duties and exercise such powers as may be directed or
delegated by the Board from time to time.  To the full extent permitted by law,
the Board may delegate to such Committee authority to exercise all the powers of
the Board while the Board is not in session.  Vacancies in the members of the
Committee shall be filled by the Board at a regular meeting or at a special
meeting for that purpose.  The Executive Committee shall keep written minutes of
its meeting and report the same to the Board when required.  The provisions of

determined.  The emergency powers granted hereunder shall be operative during
any emergency resulting from an attack on the United States or during any
nuclear or atomic disaster or during the existence of any catastrophe, or other
similar emergency condition, as a result of which a quorum of the Board of
Directors or a standing committee thereof cannot readily be convened for action
(an "emergency condition").  Said Committee shall have and may exercise all of
the powers of the Board of Directors in the management of the business and
affairs of the Corporation.  It shall act only during such emergency condition
and so long as the number of Directors able to act shall have been reduced to
fewer than five, and until a Board of Directors has been elected by the
stockholders.  Such Committee shall meet as promptly as possible after the
commencement of such an emergency condition as would activate the Committee and
at such subsequent time or times as it may designate until a Board of Directors
has been duly elected.  Such Committee shall as the first order of business
elect an Emergency Executive Committee from among its members and a chairman
thereof, who shall be the chief executive officer of the Corporation.  Such
Executive Committee shall function in the same manner and possess the same
powers as the Executive Committee of the Board of Directors, as provided in
Article III of these Bylaws, and shall have as many members as shall be provided
by resolution of the Board.  Such Committees shall make their own rules of
procedure except to the extent otherwise provided by resolution of the Board.  A
majority of the members of the Committees able to act shall constitute a quorum.
The physical presence of a member shall not be required if his vote on an action
to be taken can be obtained by available means of communication.  Any vacancy
occurring in said Committees caused by resignation, death or other incapacity
may be filled by a majority of the remaining members of the Emergency Management
Committee and any member so chosen shall serve until a Board of Directors has
been duly elected.

     SECTION 3.16 OTHER COMMITTEES.  The Board may, by resolution passed by a
majority of the whole Board, designate one or more other committees, each such
committee to consist of one or more of the directors of the Corporation.  To the
full extent permitted by law, any such committee shall have and may exercise
such powers and authority as the Board may designate in such resolution.
Vacancies in the membership of a committee shall be filled by the Board at a
regular meeting or a special meeting for that purpose.  Any such committee shall
keep written minutes of its meetings and report the same to the Board when
required.  The

                                       9

provisions of Sections 3.08, 3.09, 3.10, 3.11 and 3.12 of these Bylaws shall

Corporation shall be entitled to have a certificate or certificates, to be in
such form as the Board shall prescribe, certifying the number and class of
shares of the stock of the Corporation owned by him.  The certificates
representing shares of such stock shall be numbered in the order in which they
shall be issued and shall be signed in the name of the Corporation by the
Chairman, Vice Chairman or President or a Vice President, and by the Secretary
or an Assistant Secretary or the Treasurer or an Assistant Treasurer.  Any of or
all of the signatures on the certificates may be a facsimile.  In case any
officer, transfer agent or registrar who has signed, or whose facsimile
signature has been placed upon, any such certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued,
such certificate may nevertheless be issued by the Corporation with the same
effect as though the person who signed such certificate, or whose facsimile
signature has been placed upon, any such certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued,
such certificate may nevertheless be issued by the Corporation with the same
effect as though the person who signed such certificate, or whose facsimile
signature shall have been placed thereupon, were such officer, transfer agent or
registrar at the date of issue.  A record shall be kept of the respective names
of the persons, firms or corporations owning the stock represented by such
certificates, the number and class of shares represented by such certificates,
respectively, and the respective dates thereof, and in case of cancellation, the
respective dates of cancellation.  Every certificate surrendered to the
Corporation for exchange or transfer shall be cancelled, and no new certificate
or certificates shall be issued in exchange for any existing certificate until
such existing certificate shall have been so cancelled, except in cases provided
for in Section 6.04.

     SECTION 6.02 TRANSFERS OF STOCK.  Transfers of shares of stock of the
Corporation shall be registered on the books of the Corporation or a transfer
agent appointed as provided in Section 6.03, only upon surrender of the
certificate or certificates for such shares properly endorsed by the registered
holder thereof, or by his attorney thereunto authorized by power of attorney
duly executed, and the payment of all taxes thereon.  The person in whose name
shares of stock stand on the books of the Corporation shall be deemed the owner
thereof for all purpose as regards the Corporation.  Whenever any transfer of
shares shall be made for collateral security, and not absolutely, such fact
shall be so expressed in the entry of transfer if, when the

                                       13
<PAGE>
 
certificate or certificates shall be presented to the Corporation for
registration of transfer, both the transferor and the transferee request the
Corporation to do so.

     SECTION 6.03 REGULATIONS.  The Board may make such rules and regulations as
it may deem expedient, not inconsistent with these Bylaws, concerning the issue,
transfer and registration of certificates for shares of the stock of the
Corporation.  It may appoint, or authorize any officer or officers to appoint,
one or more transfer clerks or one or more transfer agents and one or more
registrars, and may require all certificates for stock to bear the signature or
signatures of any of them.

     SECTION 6.04 LOST, STOLEN, DESTROYED, AND MUTILATED CERTIFICATES.  In any
case of loss, theft, destruction or mutilation of any certificate of stock,
another may be issued in its place upon proof of such loss, theft, destruction
or mutilation and upon the giving of a bond of indemnity to the Corporation in
such form and in such sums as the Board may direct; provided, however, that a
new certificate may be issued without requiring any bond when, in the judgment
of the Board, it is proper so to do.

     SECTION 6.05 FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORD.  In
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any other
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board may fix, in advance, a record date, which shall not be more
than sixty (60) nor less than twenty (20) days before the date of such meeting,
nor more than sixty (60) days prior to any other action.  If in any case
involving the determination of stockholders for any purpose other than notice of
or voting at a meeting of stockholders the Board shall not fix such a record
date, the record date for determining stockholders for such purpose shall be the
close of business on the day on which the Board shall adopt the resolution
relating thereto.  A determination of stockholders entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of such
meeting; provided, however, that the Board may fix a new record date for the
adjourned meeting.

                                 ARTICLE VII.

                                INDEMNIFICATION

     SECTION 7.01 ACTIONS OTHER THAN BY OR IN THE RIGHT OF THE CORPORATION.  The
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Corporation) by reason of the fact that he
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, partnership, joint venture, trust or other
enterprise or as a member of any committee or similar body, against expenses
(including attorneys' fees), judgments, fines

                                       14
<PAGE>
 
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he 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 his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal action or proceeding, that he had
reasonable cause to believe that his conduct was unlawful.

     SECTION 7.02 ACTIONS BY OR IN THE RIGHT OF THE CORPORATION.  The
Corporation shall indemnify 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 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, partnership, joint
venture, trust or other enterprise, or as a member of any committee or similar
body, against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in,
or not opposed to, the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

     SECTION 7.03 DETERMINATION OF RIGHT OF INDEMNIFICATION.  Any
indemnification under Section 7.01 or 7.02 (unless ordered by a court) shall be
made by the Corporation only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstances because he has met the applicable standard of
conduct set forth in Sections 7.01 and 7.02.  Such determination shall be made
(i) by the Board by a majority vote of a quorum consisting of directors who were
not parties to such action, suit or proceeding, or (ii) if such a quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (iii) by the
stockholders.

     SECTION 7.04 INDEMNIFICATION AGAINST EXPENSES OF SUCCESSFUL PARTY.
Notwithstanding the other provisions of this Article, to the extent that a
director, officer, employee or agent of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred to
in Section 7.01 or 7.02, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

                                       15
<PAGE>
 
     SECTION 7.05 ADVANCE OF EXPENSES.  Expenses incurred in defending a civil
or criminal action, suit or proceeding may be paid by the Corporation in advance
of the final disposition of such action, suit or proceeding as authorized by the
Board upon receipt of an undertaking by or on behalf of the director or officer,
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as authorized in this Article.
Such expenses incurred by other employees and agents may be so paid upon such
terms and conditions, if any, as the Board deems appropriate.

     SECTION 7.06 OTHER RIGHTS AND REMEDIES.  The benefits provided by this
Article shall not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any statute, Bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

     SECTION 7.07 INSURANCE.  Upon resolution passed by the Board, the
Corporation may purchase and maintain insurance on behalf of any person who 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, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in any
such capacity, or arising out of his status as such, whether or not the
Corporation would have the power to indemnify him or hold him harmless against
such liability under the provisions of this Article.

     SECTION 7.08 CONSTITUENT CORPORATIONS.  For the purposes of this Article,
references to "the Corporation" include all constituent corporations absorbed in
a consolidation or merger as well as the resulting or surviving corporation, and
shall also include without limitation Jacobs Engineering Group Inc., a
California corporation, so that any person who is or was a director, officer,
employee or agent of such a constituent corporation or is or was serving at the
request of such constituent corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise shall stand in the same position under the provisions of this Article
with respect to the resulting or surviving corporation as he would if he had
served the resulting or surviving corporation in the same capacity.

     SECTION 7.09 EMPLOYEE BENEFIT PLANS.  For purposes of this Article,
references to "other enterprises" shall include employee benefit plans, and
references to "serving at the request of the Corporation" shall include any
service as a director, officer, employee or agent of the Corporation that
imposes a duty on, or involves services by, such director, officer, employee or
agent with respect to an employee benefit plan, its participants or
beneficiaries.

     SECTION 7.10 BROADEST LAWFUL INDEMNIFICATION.  In addition to the
foregoing, the Corporation shall, to the broadest and maximum extent permitted
by Delaware law, as the same exists from time to time (but, in case of any
amendment to or change in Delaware law, only to

                                       16
<PAGE>
 
the extent that such amendment or change permits the Corporation to provide
broader rights of indemnification than is permitted to the Corporation prior to
such amendment or change), indemnify each person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative by
reason of the fact that he is or was a director or officer of the Corporation,
or is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding than is permitted to the
Corporation prior to such amendment or change), pay to such person any and all
expenses (including attorneys' fees) incurred in defending or settling any such
action, suit or proceeding in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of the
director or officer, to repay such amount if it shall ultimately be determined
by a final judgment or other final adjudication that he is not entitled to be
indemnified by the Corporation as authorized in this Section 7.10.  The first
sentence of this Section 7.10 to the contrary notwithstanding, the Corporation
shall not indemnify any such person with respect to any of the following
matters: (i) remuneration paid to such person if it shall be determined by a
final judgment or other final adjudication that such remuneration was in
violation of law; or (ii) any accounting of profits made from the purchase or
sale by such person of the Corporation's securities within the meaning of
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or
similar provisions of any federal, state or local statutory law; or (iii)
actions brought about or contributed to by the dishonesty of such person, if a
final judgment or other final adjudication adverse to such person establishes
that acts of active and deliberate dishonesty were committed or attempted by
such person with actual dishonest purpose and intent and were material to the
adjudication; or (iv) actions based on or attributable to such person having
gained any personal profit or advantage to which he was not entitled, in the
event that a final judgment or other final adjudication adverse to such person
establishes that such person in fact gained such personal profit or other
advantage to which he was not entitled; or (v) any matter in respect of which a
final decision by a court with competent jurisdiction shall determine that
indemnification is unlawful; provided, however, that the Corporation shall
perform its obligations under the second sentence of this Section 7.10 on behalf
of such person until such time as it shall be ultimately determined by a final
judgment or other final adjudication that he is not entitled to be indemnified
by the Corporation as authorized by the first sentence of this Section 7.10 by
virtue of any of the preceding clauses (i), (ii), (iii), (iv) or (v).

     SECTION 7.11 INDEMNITY FUND.  Upon resolution passed by the Board, the
Corporation may establish a trust or other designated account, grant a security
interest or use other means (including, without limitation, a letter of credit),
to ensure the payment of any or all of its obligations arising under this
Article VII and/or any agreements that may be entered into between the
Corporation and its officers and directors from time to time.

     SECTION 7.12 SEVERABILITY.  If any part of this Article VII shall be found,
in any action, suit or proceeding or appeal therefrom or in any other
circumstances or as to any particular

                                       17
<PAGE>
 
officer, director, employee or agent to be unenforceable, ineffective or invalid
for any reason, the enforceability, effect and validity of the remaining parts
or of such parts in other circumstances shall not be affected, except as
otherwise required by applicable law.

     SECTION 7.13 AMENDMENTS.  The foregoing provisions of this Article VII
shall be deemed to constitute an agreement between the Corporation and each of
the persons entitled to indemnification hereunder, for as long as such
provisions remain in effect.  Any amendment to the foregoing provisions of this
Article VII which limits or otherwise adversely affects the scope of
indemnification or rights of any such persons hereunder shall, as to such
persons, apply only to claims arising, or causes of action based on actions or
events occurring, after such amendment and delivery of notice of such amendment
is given to the person or persons so affected.  Until notice of such amendment
is given to the person or persons whose rights hereunder are adversely affected,
such amendment shall have no effect on such rights of such persons hereunder.
Any person entitled to indemnification under the foregoing provisions of this
Article VII shall as to any act or omission occurring prior to the date of
receipt of such notice, be entitled to indemnification to the same extent as had
such provisions continued as Bylaws of the Corporation without such amendment.

                                 ARTICLE VIII.

                                 MISCELLANEOUS

     SECTION 8.01 SEAL.  The Board shall provide a corporate seal, which shall
be in the form of a circle and shall bear the name of the Corporation and words
and figures showing that the Corporation was incorporated in the State of
Delaware and the year of incorporation.

     SECTION 8.02 WAIVER OF NOTICES.  Whenever notice is required to be given by
these Bylaws or the Certificate of Incorporation or by law, the person entitled
to said notice may waive such notice in writing, either before or after the time
stated therein, and such waiver shall be deemed equivalent to notice.

     SECTION 8.03 FISCAL YEAR.  The fiscal year of the Corporation shall begin
the first day of October in each year.

     SECTION 8.04 AMENDMENTS.  Subject to the provisions of the Certificate of
Incorporation, these Bylaws and applicable law, these Bylaws or any of them may
be amended or repealed and new Bylaws may be adopted (a) by the Board, by vote
of a majority of the number of directors then in office or (b) by the vote of
the holders of not less than seventy-five (75%) percent of the total voting
power of all outstanding shares of voting stock of the Corporation in an annual
meeting of stockholders, without previous notice, or at any special meeting of
stockholders, provided that notice of such proposed amendment, repeal or
adoption is given in the notice of special meeting.  Subject to the provisions
of the Certificate of Incorporation, any Bylaws adopted or amended by the
stockholders may be amended or repealed by the Board or the stockholders.

Chairman of the Board, the President and each Vice President shall have full
power and authority on behalf of the Corporation to attend and to act and vote
at any meeting of the stockholders of any corporation in which the Corporation
may hold stock and at any such meeting shall possess and may exercise any and
all rights and powers that are incident to the ownership of such stock and which

</TABLE>
 
 1998 Compared to 1997
 
  Consolidated revenues in fiscal 1998 totalled $2.1 billion; this was $320.5
million, or 18.0 percent, more than fiscal 1997's total revenues. More than
half of this increase was attributable to the Company's comparable U.S. and
European operations (that is, those offices operating during the comparable
periods of both 1998 and 1997). The balance of the increase was attributable
to the effect of companies acquired in 1997, and in particular, to the Serete
Group.
 
  Revenues in 1998 from engineering services were $120.4 million higher than
the comparable 1997 amount. The Company considers the level of engineering
services it provides an important indicator of its overall financial
performance. Engineering services absorb a significant portion of the
Company's general and administrative expenses. In addition, the Company
believes that engineering services activity is a leading indicator of possible
future opportunities to provide construction and construction management
services. Engineering services revenues in 1998 from the Company's comparable
U.S. and European operations were approximately 8 percent higher than the 1997
amount, with the balance of the increase attributable to businesses the
Company acquired in 1997.
 
  Revenues from construction services increased $197.9 million, or 24.3
percent, from 1997 to 1998. This increase occurred in spite of the fact that
the Company completed construction on a large semiconductor project late last
year. Revenues in 1998 from maintenance services were substantially the same
as the 1997 amount. Also contributing to the overall increase in field
services revenues from 1997 to 1998 was a $96.2 million increase in
subcontract and procurement activity (the costs of which are included in both
revenues and costs).
 
                                      A-3
<PAGE>
 
  As a percent of revenues, direct costs of contracts was 87.1 percent in
1998, versus 86.9 percent in 1997. The percentage relationship between direct
costs of contracts and revenues will fluctuate from year to year depending on
a variety of factors, including the mix of business and services in the years
being compared. In general, the increase in the direct costs of the Company's
services as a percentage of revenues from 1997 to 1998 was due to a
proportionally higher percentage of the Company's total business volume coming
from field services relative to engineering services, off-set in part by an
increase in the profit margin on the Company's field services activities in
total.
 
  The Company's selling, general and administrative ("S,G & A") expenses
totalled $184.0 million in 1998; this was $23.9 million, or 14.9 percent, more
than the 1997 amount. The increase was attributable to the full-year effects
of the businesses acquired during 1997. The 1998 operating S,G & A expenses of
the Company's comparable U.S. and European operations were approximately $1.2
million lower than the corresponding 1997 amount.
 
  The Company's operating profit (defined as total revenues, less direct costs
of contracts, and S,G & A expenses) totalled $86.5 million in 1998; this was
$12.9 million higher than the comparable 1997 amount. In general, the
improvement in operating profit was due to the overall increase in business
volume in 1998 as compared to 1997, combined with better S,G & A expense
control throughout much of the Company's comparable U.S. and European
operations.
 
  Interest income, net totalled $2.7 million in 1998; this was $0.2 million
less than the 1997 amount. The decrease in net interest income was due
primarily to a reduction of rates earned on slightly higher levels of average
cash invested during 1998 as compared to 1997, combined with a small increase
in consolidated interest expense.
 
  Other expense, net totalled $0.4 million in 1998, as compared to other
income, net of $0.9 million in 1997. Included in the 1998 amount was the
approximate $8.8 million gain realized by the Company on the sale of its
office building located in Dublin, Ireland (known as "Merrion House"). Merrion
House was purchased in 1995, and the Company will continue to occupy a minor
portion of the property under a lease agreement. Off-setting the Merrion House
gain were reserves recorded in the fourth quarter of 1998 for certain settled
and pending litigation.
 
 1997 Compared to 1996
 
  Consolidated revenues in 1997 totalled $1.8 billion, which was substantially
the same as the 1996 amount. Revenues in 1997 from engineering services,
however, increased by $74.4 million, or 11.9 percent, from 1996. The increase
in engineering services activity was due in part to certain acquisitions the
Company completed in 1997, and in part to internal growth.
 
  Revenues from construction services declined 12.1 percent from 1996 to 1997.
This decline was attributable primarily to the completion of several large
projects late in 1996 and early in 1997, which were not replaced by new
construction projects. Revenues from maintenance services increased
7.7 percent from 1996 to 1997. This increase was due to a pick-up from 1996 in
the level of turnaround activity, combined with new awards for maintenance
services. Contributing to the decrease in overall field services revenues from
1996 to 1997 was an $83.0 million decline in subcontract and procurement
activity.
 
  As a percent of revenues, direct costs of contracts was 86.9 percent in
1997, versus 88.4 percent in 1996. In general, the decrease in this percentage
relationship from 1996 to 1997 was due to a proportionally higher percentage
of the Company's total business volume coming from engineering services
relative to field services.
 
  The Company's S,G & A expenses totalled $160.2 million in 1997; this was
$16.7 million, or 11.6 percent, more than the 1996 amount. Of the increase,
approximately $12.8 million was attributed
 
                                      A-4
<PAGE>
 
to businesses acquired during 1997. The increase in S,G & A expenses
corresponds to the increase in the Company's engineering services, and
reflects its continuing efforts to control such costs throughout its
operations.
 
  The Company's operating profit totalled $73.6 million in 1997; this was $9.0
million more than the 1996 amount. In general, the improvement was due to the
increase in engineering services discussed above, combined with higher margin
rates for all of the Company's services.
 
  Interest income, net totalled $3.0 million in 1997; this was $1.5 million
more than the 1996 amount. The increase in net interest income was due
primarily to higher levels of cash invested during 1997 as compared to 1996,
combined with slightly better rates of interest earned on such investments.
 
BACKLOG
 
  The following table summarizes the Company's total backlog at September 30,
1998, 1997 and 1996 (in millions):
 
<TABLE>

   Engineering services.............................. $1,004.5 $  912.1 $  845.3

                                                      ======== ======== ========
</TABLE>
 
  At any given time, backlog represents the amount of revenues the Company
expects to record in the future from performing work under contracts that have
been awarded to it. With respect to maintenance projects, however, it is the
Company's policy to include in backlog only the amount of revenues it expects
to receive during the succeeding year, regardless of the remaining life of the
contract, unless the Company does not expect the contract to be renewed. With
respect to contracts relating to projects for agencies of the U.S. federal
government, it is the Company's policy to include in backlog the full contract
award.
 
  Total backlog at September 30, 1998 included approximately $800.0 million of
contracts for work to be performed either directly or indirectly for agencies
of the U.S. federal government. This compares to approximately $923.0 million
and $1.0 billion of federal backlog at September 30, 1997 and 1996,
respectively. Most of these contracts extend beyond one year. In general,
these contracts must be funded annually (i.e., the amounts to be spent under
the contract must be appropriated by Congress to the procuring agency, and
then the agency must allot these sums to the specific contracts).
 
  The Company's backlog increased $299.8 million from 1996 to 1997, and it
increased by $279.5 million from 1997 to 1998. A significant portion of the
1997 increase was due to new awards in the petroleum and chemicals industries,
combined with backlog acquired in conjunction with the acquisitions made by
the Company in 1997. Most of the 1998 increase was due to new awards in the
chemicals, refining and pharmaceuticals areas of the Company's business.
 
  Of total backlog at September 30, 1998, the Company estimates that
approximately 50 percent will be realized as revenues within the next year.
 
  In accordance with industry practice, substantially all of the Company's
contracts may be terminated by the client. However, the Company has not
experienced cancellations which have had a material effect on the reported
backlog amounts. In the situation where a client terminates a contract, the
Company would ordinarily be entitled to receive payment for work performed up
to the date of termination and, in certain instances, may be entitled to
allowable termination and cancellation costs. Additionally, the Company's
backlog at any given time is subject to changes in the scope of services to be
provided as well as increases or decreases in costs relating to the contracts
included therein.
 
                                      A-5
<PAGE>
 
EFFECTS OF INFLATION
 
  Because a significant portion of the Company's revenues over recent years
has been earned under cost-reimbursable type contracts, the effects of
inflation on the Company's financial condition and results of operations have
been generally low. However, as the Company expands its business into markets
and geographical areas where fixed-price and lump-sum work is more prevalent,
inflation may begin to have a larger impact on the Company's results of
operations. To the extent permitted by competition, the Company intends to
continue to emphasize contracts which are either cost-reimbursable or
negotiated fixed-price. For contracts the Company accepts with fixed-price or
lump-sum payment terms, the Company monitors closely the actual costs on the
project as they compare to the budget estimates. On these projects, the
Company also attempts to secure fixed-price commitments from key
subcontractors and vendors. However, due to the competitive nature of the
Company's industry, combined with the fluctuating demands and prices
associated with personnel, equipment and materials the Company traditionally
needs to perform on its contracts, there can be no guarantee that inflation
will not effect the Company's results of operations in the future.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's cash and cash equivalents increased $45.3 million during 1998.
This compares to a net decrease of $6.9 million during 1997, and a net
increase of $23.7 million in 1996. The current year increase was due primarily
to cash provided by operations ($90.5 million), offset in part by cash used in
investing activities ($9.6 million) and financing activities ($35.4 million).
 
  Operations provided $90.5 million of cash and cash equivalents in 1998. This
compares to net contributions of cash of $43.9 million in 1997, and $54.3
million in 1996. The $46.5 million increase in cash provided by operations in
1998 as compared to 1997 was due primarily to an increase in net income ($7.5
million) combined with the positive effects on cash of the timing of cash
receipts and payments within the Company's working capital accounts (which
resulted in a net increase to cash of $44.9 million, comparing 1998 activity
to 1997). This favorable increase was off-set in part by higher gains on
disposals of fixed assets in 1998 as compared to 1997 ($7.8 million).
 
  The Company's investing activities used $9.6 million of cash and cash
equivalents in 1998. This compares to net uses of cash of $69.5 million in
1997 and $40.0 million in 1996. The $59.9 million decrease in cash used in
investing activities in 1998 as compared to 1997 was due primarily to the
increases in cash provided from sales of property and equipment ($26.5
million; most of which related to the sale of Merrion House) and marketable
securities ($8.2 million). Also contributing to the decrease in cash used for
investing activities in 1998 as compared to 1997 was the net decrease in other
assets (consisting primarily of collections of certain notes receivable which
resulted in an increase to cash of $25.4 million, comparing 1998 activity to
1997). Lastly, the Company used $20.0 million in 1997 for purchases of
marketable securities; only $5.4 million was used for such purposes in 1998,
which also contributed to the net reduction of cash used for investing
activities in 1998 as compared to 1997 ($14.6 million).
 
  These positive changes in cash flows from investing activities were off-set
in part by an increase in cash used for property and equipment additions
($18.3 million). Included in the 1998 additions to property and equipment were
costs incurred and capitalized relating to the Company's new, leased
headquarters facility in Pasadena, California. Also included were costs
incurred in connection with the purchase of certain real property located in
Charleston, South Carolina. This latter property is being developed into a
new, modular design and manufacturing facility, which will enhance and expand
the Company's existing modular construction capabilities. The total estimated
cost of the project is approximately $19.0 million, and will be financed
through working capital and the sale of the Company's existing modular
construction facilities located in Orangeburg, South Carolina.
 
                                      A-6
<PAGE>
 
  The Company's financing activities used $35.4 million of cash and cash
equivalents in 1998. This compares to a net contribution of cash of $20.3
million in 1997 and $9.6 million in 1996. The $55.7 million decrease from 1997
to 1998 in cash flows from financing activities was due primarily to cash used
by the Company in 1998 to reduce its long-term debt, as compared to 1997
wherein the Company was a net borrower under this facility (creating a
negative variance of $50.7 million). Also contributing to the decrease in cash
flows from financing activities from 1997 to 1998 was an overall increase in
purchases of treasury stock ($6.0 million). Off-setting these negative
variances in part was a slight increase from 1997 to 1998 in cash flows from
the exercise of stock options, and other miscellaneous financing items ($0.9
million).
 
  The Company believes it has adequate capital resources available to fund
operations in 1999 and beyond. The Company's consolidated working capital
position totalled $197.7 million at September 30, 1998; this was $19.5 million
more than the comparable 1997 amount. At September 30, 1998, the Company had a
total of $42.7 million available under all of its short-term bank credit
facilities, against which $0.2 million was outstanding in the form of direct
borrowings. The amounts outstanding at September 30, 1998 relate entirely to
borrowings by the Company's Chilean subsidiary (in order to hedge against
possible fluctuations in foreign currency exchange rates, the Company
typically establishes lines of credit with banks providing for short-term
borrowing capacity in local currencies). In addition to its short-term credit
facilities, the Company also had $18.8 million of borrowing capacity available
to it at September 30, 1998 under its long-term, revolving credit agreement.
 
  As discussed in Note 10 to the Consolidated Financial Statements, in
December 1998, the Company signed an agreement and plan of merger with the
Sverdrup Corporation ("Sverdrup"). The agreement is subject to the approval of
the shareholders of Sverdrup, the expiration or termination of the Hart-Scott-
Rodino Act waiting period, and other contingencies. As a result of the
transactions contemplated in the merger agreement, Sverdrup will become, upon
closing of the transaction (which is not expected to occur until early in the
second quarter of fiscal 1999), a wholly-owned subsidiary of the Company.
Total consideration to be paid by the Company at closing will be approximately
$198.0 million. The Company intends to finance the merger price through a
combination of bank borrowings (under a new, long-term revolving credit
facility) and internal funds. The Company does not believe that the financing
of this transaction or the possible ownership of Sverdrup will have a
materially adverse affect on its liquidity during 1999.
 
YEAR 2000 READINESS
 
  The following discussion of the Year 2000 issue contains numerous "forward-
looking statements". See "Forward-Looking Statements and Other Safe Harbor
Applications", below, for a discussion of factors to be considered in reading
forward-looking statements.
 
  This discussion of "Year 2000" (or "Y2k") relates to the possible inability
of computers, hardware or software to perform properly because they are unable
to interpret date information correctly after December 31, 1999, and includes
all of the associated consequences of such failures on the Company's
operations. If not corrected, such situations could result in computer-system
failures or miscalculations causing disruptions in the Company's operations,
including a temporary inability to process transactions, pay employees,
vendors and subcontractors, send invoices or engage in similar, normal
business activities.
 
The Year 2000 Task Force
 
  The Company began its assessment of its Year 2000 readiness during fiscal
1997. In that year the Company organized a Year 2000 task force comprised
primarily of Company employees. The Company has identified four information
technology ("IT") and non-IT areas for which Y2k compliance is critical to the
normal and routine operations of the Company. These areas are: (1) internally-
 
                                      A-7
<PAGE>
 
developed computer software; (2) commercial off-the-shelf software; (3)
computer hardware and embedded processors; and (4) facilities-related
applications and processes, such as telecommunications and equipment with
embedded chips.
 
  Also included in the Company's Year 2000 compliance program are the
hardware, software, and other applications issues relating to the Company's
financial and accounting systems. In 1997 the Company embarked under a
completely separate initiative (referred to as the "Global Financial Systems
Project") to migrate most of its existing financial and accounting systems to
a single accounting system, which eventually will be utilized by all of the
Company's operations worldwide. The Global Financial Systems Project will make
use of commercial off-the-shelf software with internally-developed program
interfaces. Based on assurances from the third-party provider of the commercial
off-the-shelf software, and discussions with the third-party consultants
employed by the Company to assist in the system conversion, the Company believes
its Global Financial Systems Project will be Y2k compliant by the year 2000.
 
The Year 2000 Program
 
  The Company's plan to address the Year 2000 problem involves the following
phases: inventory, assessment, remediation, testing and implementation.
 
    The "inventory" phase describes the process of identifying all hardware
  and software components within each of the aforementioned areas of the
  Company's business which need to be made Y2k compliant, as well as defining
  the business impacts of failing to make such components Y2k compliant.
 
    The "assessment" phase requires that an evaluation be made of each
  affected system to determine what actions need to occur to make such
  systems Y2k compliant.
 
    The "remediation" phase involves the actual repair or replacement of
  those hardware and software components critical to each affected business
  process.
 
    After remediation, the "testing" phase will verify if the affected
  systems have been properly repaired. If during this phase it is determined
  that additional repairs are required, such repairs will be made, or
  alternative corrective actions taken.
 
    The purpose of the "implementation" phase will be to bring the repaired
  systems on-line and integrated with the rest of the Company's operations.
 
Third Party Compliance
 
  The Company is also evaluating the possible effects of the Year 2000 issue
on its clients, suppliers, subcontractors and vendors. Although the possible
effects of the Year 2000 issue on these parties are beyond the control of the
Company, the Company has initiated a process to communicate with these parties
to inform them of the Company's Year 2000 strategy and to determine their own
Year 2000 strategy and progress.
 
Cost of the Year 2000 Program
 
  The Company estimates the total cost of its Year 2000 compliance program at
approximately $5.8 million, consisting of both internal and external costs,
and including a maximum of $2.0 million for new hardware and software
(although a substantial portion of such new hardware and software would have
been purchased by the Company through the regular and routine upgrading of
systems). Such hardware and software will be capitalized and depreciated over
the estimated useful lives of the related assets. All other expenditures will
be charged to expense. As of September 30, 1998, the Company had spent
approximately $0.4 million against its estimated budget.
 
                                      A-8

Progress of the Year 2000 Program
 
  As of September 30, 1998, the Company was actively engaged in one or more
compliance phases with respect to each of the four business areas described
above. Although there can be no guarantee of complete readiness by the year
2000, the Company believes each of the business areas described above will be
Y2k compliant by November 1999, or be substantially compliant by that time
such that further remediation and testing, if any, will not be significant to
its operations. However, as discussed above, the Company has not completed its
Year 2000 compliance program. In the event the Company does not complete its
program, or fails to properly identify and modify critical business
applications, there may be an interruption to the Company's business that may
have a materially adverse affect on its future financial condition and results
of operations. In addition, year 2000-related disruptions in the economy in
general may also have a materially adverse affect on its future financial
condition and results of operations.
 
Risks
 
  The failure to identify and correct a Year 2000 problem could result in an
interruption in, or failure of, certain normal business activities or
operations. The Company does not expect such failures to have a materially
adverse effect on its results of operations or financial condition. However,
because of the general uncertainty about Year 2000 readiness throughout the
world economy, which results in uncertainties regarding the readiness of the
Company's vendors, contractors and clients, the Company is currently unable to
determine whether Year 2000 problems may have a materially adverse effect on
its results of operations or financial condition. As the Company's Year 2000
compliance program progresses, the level of uncertainty about this matter is
being reduced, especially as to uncertainties about the Company's own degree
of Year 2000 compliance and the compliance of its suppliers, contractors and
clients.
 
Worst Case Scenario
 
  It is not presently possible to describe a reasonably likely "worst case
Year 2000 scenario" without making numerous assumptions. The Company presently
believes that a most likely worst case scenario would make it necessary for
the Company to replace some suppliers or contractors, rearrange some work
plans, or perhaps interrupt some office and field activities. Assuming this
assessment is correct, the Company does not believe that such circumstances
would have a materially adverse effect on its financial condition or results
of operations, even if it is necessary to incur additional costs to correct
unanticipated compliance failures.
 
Contingency Plans
 
  The Company currently has no contingency plans in place in the event it does
not complete all phases of its Year 2000 compliance program by December 31,
1999. However, it expects to have completed enough of its compliance work by
March 1999 that it will be able to identify those business areas for which
contingency plans will be necessary, and it will develop the required
contingency plans at that time. The Company continues to monitor carefully the
progress of its Year 2000 program and its state of readiness on a regular
basis. Any future contingency plan will be based on its best estimates of
numerous factors, which, in turn will be derived by relying on numerous
assumptions about future events. However, there can be no assurance that these
assumptions or estimates will have been correctly made, or that the Company
will have anticipated all relevant factors, or that there will not be a delay
in or increased costs associated with the Company's Year 2000 program. Any
delay in implementation of the Year 2000 program could affect the Company's
Year 2000 readiness. Specific factors that might cause the actual outcome to
differ from the projected outcome include, without limitation, the continued
availability of personnel and consultants trained in the computer programming
skills necessary for remediation of Year 2000 problems, the ability to locate
and correct all relevant
 
                                      A-9
<PAGE>
 
computer codes and embedded software, timely responses by third parties,
including suppliers, contractors and clients, and the ability to implement
interfaces between new systems and systems not being replaced.
 
  The foregoing discussion does not cover the degree of Year 2000 compliance
achieved by Sverdrup Corporation. Additionally, this discussion regarding the
Year 2000 issue is a "Year 2000 Readiness Disclosure" as that term is
discussed in the Year 2000 Information and Readiness Disclosure Act of 1998.
 
EFFECTS OF RECENTLY-ISSUED ACCOUNTING STANDARDS
 
  In June 1997, the Financial Accounting Standards Board ("FASB") adopted
Statement of Financial Accounting Standards ("SFAS") No. 130 -- Reporting
Comprehensive Income, and it also adopted SFAS No. 131 -- Disclosures about
Segments of an Enterprise and Related Information. In February 1998, the FASB
adopted SFAS No. 132 -- Employers' Disclosures about Pensions and Other
Postretirement Benefits. And in June 1998, the FASB adopted SFAS No. 133 --
 Accounting for Derivative Instruments and Hedging Activities.
 
  SFAS No. 130 will be effective for the Company beginning with the first
quarter of fiscal 1999. This standard establishes guidelines for the reporting
and display of "comprehensive income" and its components. Comprehensive income
is defined to include all changes in the Company's equity from nonowner
sources, and would include cumulative foreign currency translation adjustments
and unrealized gains and losses on certain marketable securities, among other
items.
 
  SFAS No. 131 will also be effective for the Company beginning with the first
quarter of fiscal 1999. This standard supersedes SFAS No. 14, and establishes
standards for the way public companies report information about their
operating segments in both annual and interim financial statements. It also
requires public companies to report descriptive information about the way
their operating segments were determined, the products and services provided
by their operating segments, and information about their major customers.
 
  SFAS No. 132 will be effective for the Company's 1999 year-end consolidated
financial statements. This standard amends existing disclosure requirements
regarding pension plans and other plans providing postretirement benefits, and
specifically requires additional information on changes in benefit obligations
and fair values of plan assets.
 
  SFAS No's. 130, 131 and 132 are all disclosure-oriented pronouncements. That
is, they do not effect the way in which the Company will account for any item
or transaction included in its consolidated financial statements. Rather, they
require that certain information be presented differently, or additional
information provided, or that the information presented be discussed by the
Company. The Company does not believe that SFAS No. 133 applies to it.
 
FORWARD-LOOKING STATEMENTS AND OTHER SAFE HARBOR APPLICATIONS
 
  Statements included in this Management's Discussion and Analysis that are
not based on historical facts are "forward-looking statements", as that term
is discussed in the Private Securities Litigation Reform Act of 1995. Such
statements are based on management's current estimates, expectations and
projections about the issues discussed, the industries in which the Company
operates and the services it provides. By their nature, such forward-looking
statements involve risks and uncertainties. The Company cautions the reader
that a variety of factors could cause business conditions and results to
differ materially from what is contained in its forward-looking statements.
These factors include, but are not necessarily limited to, the following:
increase in competition by foreign and domestic competitors; availability of
qualified engineers and other professional staff needed to execute contracts;
the timing of
 
                                     A-10
<PAGE>
 
new awards and the funding of such awards; the ability of the Company to meet
performance or schedule guarantees; cost overruns on fixed, maximum or unit
priced contracts; the outcome of pending and future litigation and
governmental proceedings; the cyclical nature of the individual markets in
which the Company's customers operate; the outcome or closing of any merger or
acquisition transaction, including the nature and extent of any related
financing, and the amount of any contingent consideration the Company may be
required to make in the future in connection with any merger or acquisition
transaction; and the Company's success in dealing with the Year 2000 issues
discussed above under "Year 2000 Readiness". The preceding list is not all-
inclusive, and the Company undertakes no obligation to update publicly any
forward-looking statements, whether as a result of new information, future
events or otherwise. Readers of this Management's Discussion and Analysis
should also read the Company's most recent Annual Report on Form 10-K for a
further description of the Company's business, legal proceedings and other
information that describes factors that could cause actual results to differ
from such forward-looking statements.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ACCOUNTING POLICIES
 
 Basis of Presentation
 
  The consolidated financial statements include the accounts of Jacobs
Engineering Group Inc. and its subsidiaries (the "Company"). All significant
intercompany accounts and transactions have been eliminated. Certain balances
in the accompanying 1997 consolidated balance sheet have been reclassified to
conform to the 1998 presentation.
 
 Description of the Business
 
  The Company's principal business is that of providing professional
engineering, construction and construction management, and maintenance
services to its industrial, commercial and government clients. The Company
provides its services from offices located primarily throughout the United
States, Europe and India. The Company provides its services under cost-
reimbursable, cost-reimbursable with a guaranteed maximum, and fixed-price
contracts. The percentage of revenues realized from each of these types of
contracts in each of the years ended September 30, 1998, 1997 and 1996 was as
follows:
 
<TABLE>

                                                                  1998  1997  1996
                                                                  ----  ----  ----
   <S>                                                            <C>   <C>   <C>

   Fixed-price...................................................  18    16    16
   Guaranteed maximum............................................   1     2     2
</TABLE>
 
  For the years ended September 30, 1998, 1997 and 1996, projects with or for
the benefit of agencies of the U.S. federal government accounted for 12.1
percent, 12.0 percent and 8.7 percent, respectively, of total revenues. Within
the private sector, no single client accounted for 10 percent or more of total
revenues in either 1998 or 1996. One private-sector client accounted for 15.3
percent of total revenues in 1997.
 
 Revenue Accounting for Contracts
 
  In general, the Company recognizes revenues at the time services are
performed. On cost-reimbursable contracts, revenue is recognized as costs are
incurred, and includes applicable fees earned through the date services are
provided. On fixed-price contracts, revenues are recorded using the
percentage-of-completion method of accounting by relating contract costs
incurred to date to total estimated contract costs at completion. Contract
costs include both direct and indirect costs. Contract losses are provided for
in their entirety in the period they become known, without regard to the
percentage-of-completion.
 
  Some of the Company's contracts with the U.S. federal government, as well as
certain contracts with commercial clients, provide that contract costs
(including indirect costs) are subject to audit and adjustment. For all such
contracts, revenues have been recorded based upon those amounts expected to be
realized upon final settlement.
 
  As is common in the industry, the Company executes certain contracts jointly
with third parties through partnerships and joint ventures. For certain of
these contracts, the Company recognizes its proportionate share of venture
revenues, costs and operating income in its consolidated statements of income.

</TABLE>
 
  Revenues were earned from unaffiliated customers located primarily within
the respective geographic areas. Operating profit is defined as total
revenues, less direct costs of contracts, and selling, general and
administrative expenses, and excludes corporate expenses. Identifiable assets
exclude general corporate assets (such as cash in excess of local working
capital requirements, and investments). The results of the Company's
operations in Mexico and Chile were not material in either 1998 or 1997.
 
 Cash Equivalents
 
  The Company considers all highly liquid investments with original maturities
of less than three months as cash equivalents. Cash equivalents at September
30, 1998 and 1997 consisted primarily of time certificates of deposit.
 
 Marketable Securities and Investments
 
  The Company's investments in equity and debt securities are classified as
either trading securities (shown as "Marketable securities" in the
accompanying consolidated balance sheets), held-to-maturity securities or
available-for-sale securities (the latter two are included as long-term
investments in "Other noncurrent assets" in the accompanying consolidated
balance sheets). Management determines the appropriate classification of all
its investments at the time of purchase and reviews such designations at each
balance sheet date.
 
  Trading securities are stated at fair value with unrealized gains or losses
included in "Other income, net" in the accompanying consolidated statements of
income. Held-to-maturity securities are carried at cost, or amortized cost if
a premium was paid or a discount received at the time of purchase. Marketable
equity securities not held for trading and debt securities not classified as
held-to-maturity are classified as available-for-sale. Available-for-sale
securities are stated at fair value, with the unrealized gains or losses, net
of taxes, reported in the "Other" component of stockholders' equity. The
amount of unrealized gains, net of taxes, recorded at September 30, 1998 and
1997 totalled $900 and $114,000, respectively.

</TABLE>
 
  Included in marketable securities at September 30, 1998 was a $16,059,200
deposit with a U.S. bank made under a managed investment program ($20,000,000
was on deposit with the same bank at September 30, 1997). The bank has full
investment and dispositive powers over the assets held in the account. The
program emphasizes the preservation of capital through investment-grade,
marketable debt instruments which have maximum maturities of ten years.
 
 Receivables and Customers' Advances
 
  Included in receivables at September 30, 1998 and 1997 were unbilled amounts
of $106,072,200 and $75,220,700, respectively. Unbilled receivables represent
amounts earned under contracts in progress, but not yet billable under the
terms of those contracts. These amounts become billable according to the
contract terms which usually consider the passage of time, achievement of
certain milestones or completion of the project. Included in unbilled
receivables at September 30, 1998 and 1997 were contract retentions totaling
$11,808,000 and $5,708,100, respectively. Substantially all unbilled
receivables are billed and collected in the subsequent fiscal year.
 
  Customers' advances in excess of related revenues represent cash collected
from clients on contracts in advance of revenues earned thereon, as well as
billings to clients in excess of costs and earnings on uncompleted contracts.
Substantially all such amounts are earned in the subsequent fiscal year.
 
 Property, Equipment and Improvements
 
  Property, equipment and improvements are stated at cost and consisted of the

  Depreciation and amortization are provided using primarily the straight-line
method over the estimated useful lives of the assets, or, in the case of
leasehold improvements, over the remaining term of the lease, if shorter.
Estimated useful lives range from 20 to 40 years for buildings, from 3 to 10
years for equipment and from 4 to 10 years for leasehold improvements.

 Net Income Per Share
 
  Effective with the first quarter of fiscal 1998, the Company adopted, and
retroactively applied, Statement of Financial Accounting Standards No. 128 --
Earnings per Share ("SFAS No. 128"). Accordingly, basic earnings per share
("EPS") has been computed by dividing net income by the weighted average
number of shares of common stock outstanding during each period presented.
Diluted EPS has been computed by dividing net income by the weighted average
number of shares of common stock and dilutive securities outstanding
(consisting solely of nonqualified stock options). The following table
reconciles the denominator used to compute basic EPS to the denominator used
to compute diluted EPS (in thousands):

 Stock-based Compensation
 
  The Company accounts for stock issued to employees and outside directors in
accordance with APB Opinion No. 25 -- Accounting for Stock Issued to Employees
("APB No. 25"). APB No. 25 prescribes an intrinsic value based method for
accounting for stock options. Since the stock issued to participants in
Company's stock purchase and stock option plans (described in Note 4., below)
have little or no intrinsic value as of the grant date, no compensation cost
is recorded.
 
 Concentrations of Credit Risk/Use of Estimates
 
  The Company's cash balances and short-term investments are maintained in
accounts held by major banks and financial institutions in the U.S. and
Europe. Also, as is customary in the industry, the Company grants
uncollateralized credit to its clients, which include the federal government
and large, multi-national corporations operating in a broad range of
industries. In order to mitigate its credit risk, the Company continually
evaluates the credit worthiness of its major commercial clients.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that necessarily affect certain amounts reported in its
consolidated financial statements. The more significant estimates affecting
amounts reported in the consolidated financial statements relate to revenues
under long-term construction contracts and self-insurance accruals. Actual
results could differ from those estimates.
 
2. ACQUISITIONS
 
  In February 1997, the Company acquired for cash certain physical assets and
contracts of an engineering business with operations in Denver, Colorado and
Santiago, Chile. Also in February 1997, the Company increased, in a cash
transaction, its ownership interest from 40 percent to 51 percent in an
affiliated entity headquartered in Mumbai, India (this interest was increased
to 70 percent in a cash transaction in September 1997). In April 1997, the
Company acquired for cash and notes certain assets and liabilities of an
engineering business headquartered in Green Bay, Wisconsin. Finally, in July
1997, the Company completed the acquisition of the remaining interests of
several engineering and construction companies comprising the Serete Group,
which is headquartered in France.
 
  The sum of the individual purchase prices totalled $29,781,500. Each of
these acquisitions has been accounted for as a purchase, and the results of
operations of each acquired business have been included in the Company's
consolidated results of operations since the respective dates of acquisition.
The purchase price allocations resulted in goodwill of approximately
$39,035,700. The pro forma effects on the Company's consolidated results of
operations assuming these acquisitions had occurred at the beginning of fiscal
1996 and fiscal 1997 are not material.
 
3. NOTES PAYABLE TO BANKS AND LONG-TERM DEBT
 
 Short-term Credit Arrangements
 
  At September 30, 1998, the Company had approximately $42,748,000 available
through multiple bank lines of credit, under which the Company may borrow on
an overdraft or short-term basis. Interest under these lines is determined at
the time of borrowing based on the banks' prime or base rates, rates paid on
certificates of deposit, the banks' actual costs of funds or other variable
rates. Most of the agreements require the payment of a fee based on the amount
of the facility. The Company is also required to maintain certain minimum
levels of working capital and net worth. Two of the agreements limit
borrowings by the amount of letters of credit outstanding under the facility.
Borrowings under the lines are generally unsecured, and the lines extend
through the second and third fiscal quarters of 1999.
 
  Other information regarding the lines of credit for the years ended
September 30, 1998, 1997 and 1996 follows (dollars in thousands):

  Borrowings under the revolving credit agreement bear interest at either
fixed rates offered by the banks at the time of borrowing, or at variable
rates based on the agent bank's base rate, LIBOR or the latest federal funds
rate. The agreement requires the Company to maintain a minimum tangible net
worth of at least $160,000,000 plus 50 percent of consolidated net income
after October 1, 1994 ($247,020,000 at September 30, 1998), a minimum coverage
ratio of certain defined fixed charges and a minimum ratio of debt to tangible
net worth. The agreement also restricts the payment of cash dividends and
requires the Company to pay a facility fee of 0.15 percent of the total amount
of the commitment. The agreement extends through August 2000.
 
  The mortgage loan was incurred in connection with the purchase of the
Company's offices located in Dublin, Ireland. The loan was paid-off when the
Company sold the property in the fourth quarter of 1998.
 
  Interest expense for the years ended September 30, 1998, 1997 and 1996 was
$2,356,400, $2,226,100 and $2,777,400, respectively, and has been included
with interest income in the accompanying consolidated statements of income.
Interest payments made during each of these years totalled $2,517,100,
$1,801,500 and $2,552,300, respectively.
 
4. STOCK PURCHASE AND STOCK OPTION PLANS
 
 Stock Purchase Plan
 
  The Company's 1989 Employee Stock Purchase Plan (the "1989 ESPP") provides
for the granting of options to participating employees to purchase shares of
the Company's common stock. The participants' purchase price is the lower of
90 percent of the common stock's closing market price on either the first or
last day of the option period (as defined). A summary of shares issued through
the 1989 ESPP for the years ended September 30, 1998, 1997 and 1996 follows:

the issuance of shares of common stock to employees and outside directors. The
Company may grant four types of incentive awards under the 1981 Plan:
incentive stock options, nonqualified stock options, stock appreciation rights
and restricted stock. At September 30, 1998, there were 2,963,300 shares of

  Options outstanding at September 30, 1998 consisted entirely of nonqualified
stock options. The 1981 Plan allows participants to satisfy the exercise price
on exercises of stock options by tendering to the Company shares of the
Company's common stock already owned by the participants. Shares so tendered
are retired and canceled by the Company and are shown as repurchases of common
stock in the accompanying consolidated statements of stockholders' equity.
 
  During the years ended September 30, 1998, 1997 and 1996, the Company issued
12,000, 5,500 and 9,000 shares, respectively, of restricted stock under the
1981 Plan. Upon issuance of restricted stock, unearned compensation equivalent
to the market value of the stock issued (determined on the date of grant) is
charged to stockholders' equity and subsequently amortized against income over
the periods during which the restrictions lapse ($366,300, $329,900 and
$285,800 of compensation expense was recognized in 1998, 1997 and 1996,
respectively). The restrictions generally relate to the recipient's ability to
sell or otherwise transfer the stock. There are also restrictions that subject
the stock to forfeiture back to the Company until earned by the recipient
through continued employment. The restrictions lapse over five years.

 Pro Forma Disclosures
 
  As discussed in Note 1., above, the Company accounts for stock issued to
employees and outside directors in accordance with APB No. 25. In October
1995, the Financial Accounting Standards Board adopted SFAS No. 123 --
Accounting for Stock-Based Compensation. SFAS No. 123 prescribes an optional,
fair-value based method of accounting for stock issued to employees and
others. The Company's pro forma net income and net income per share in 1998,
1997 and 1996 using the Black-Scholes option valuation model for stock awards
in those years follows, along with a summary of the significant assumptions
used in the valuation (dollars in thousands, except earnings per share):

  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. Additionally, option valuation models require the use of
highly subjective assumptions including the expected volatility of the
underlying stock price. Because the Company's stock options possess
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, the Company believes that existing models do not
necessarily provide a reliable single measure of the fair value of its stock
options.
 
  The pro forma effects of SFAS No. 123 on reported net income as presented
above is not necessarily representative of the pro forma effects in future
years.
 
5. SAVINGS, DEFERRED COMPENSATION AND PENSION PLANS
 
 Savings Plans
 
  The Company maintains employee savings plans (qualified 401(k) retirement
plans) covering substantially all of the Company's domestic, nonunion
employees. For the years ended September 30, 1998, 1997 and 1996, Company
contributions to these plans totalled $9,568,700, $8,710,500 and $8,000,100,
respectively.
 
 Deferred Compensation Plans
 
  The Company's Executive Security Plan ("ESP") and Executive Deferral Plans
("EDP") are nonqualified deferred compensation programs that provide benefits
payable to directors, officers and certain key employees or their designated
beneficiaries at specified future dates, upon retirement or death. Benefit
payments under both plans are funded by a combination of contributions from
participants and the Company, and most of the participants are covered by life
insurance policies with the Company designated as the beneficiary. Amounts
charged to expense relating to these programs for the years ended September
30, 1998, 1997 and 1996 were $1,588,800, $1,672,600 and $1,781,200,
respectively. Included in other deferred liabilities in the accompanying

balance sheets at September 30, 1998 and 1997 was $22,847,700 and $23,446,800,
respectively, relating to the ESP and EDP plans.
 
 Pension Plans
 
  In the United States, the Company contributes to various trusteed pension
plans covering hourly construction employees under industry-wide agreements.
Contributions are based on the hours worked by employees covered under these
agreements and are charged to direct costs of contracts on a current basis.
Information from the plans' administrators is not available to permit the
Company to determine its share of unfunded benefits, if any. Company
contributions to these plans totalled $4,025,300, $2,694,700 and $3,538,900
for the years ended September 30, 1998, 1997 and 1996, respectively.
 
  The Company's U.K. subsidiary sponsors a contributory defined benefit
pension plan covering substantially all permanent, full-time employees at
least 21 years of age. Benefits are based on length of service and the
employee's highest average salary for any three consecutive years in the plan,
or, if higher, the employee's salary in the final year in the plan. The
Company's funding policy is to fund the actuarially-determined accrued
benefits, allowing for projected compensation increases using the projected
unit method. The following table presents the funded status of the plan as of
September 30, 1998 and 1997 (in thousands):

of the plan were as follows: weighted average discount rate -- 6.5 percent;
weighted average rate of increase in compensation -- 4.5 percent; and,
weighted average rate of return on pension assets -- 7.0 percent. At September
30, 1998, the majority of the plan's assets were invested in equity securities
(primarily those of companies trading in the U.K. and other European stock
markets) and fixed income securities.

  The Company maintains insurance coverage for various aspects of its business
and operations. The Company has elected, however, to retain a portion of
losses that occur through the use of various deductibles, limits and
retentions under its insurance programs. This situation may subject the
Company to some future liability for which it is only partially insured, or
completely uninsured. The Company intends to mitigate any such future
liability by continuing to exercise prudent business judgment in negotiating
the terms and conditions of its contracts.

base payments of $432,000 per year to either the Chairman or, in the event of
his death, his beneficiary. The agreement also provides that the Chairman may
participate in any bonus plan sponsored by the Company, specifies certain
promotional and other activities to be performed by the Chairman in the event
he leaves employment with the Company and contains other provisions, including
some intended to prevent the Chairman from entering into any form of
competition with the Company.
 
  In the normal course of business, the Company is subject to certain
contractual guarantees and litigation. Generally, such guarantees relate to
project schedules and plant performance. Most of the litigation involves the
Company as a defendant in workers' compensation, personal injury and other
similar lawsuits. In addition, as a contractor for many agencies of the United
States Government, the Company is subject to many levels of audits,
investigations and claims by, or on behalf of, the government with respect to
its contract performance, pricing, costs, cost allocations and procurement
practices. Management believes, after consultation with counsel, that such
guarantees, litigation, and United States Government contract-related audits,
investigations and claims should not have any material adverse effect on the
Company's consolidated financial statements.
 
  Letters of credit outstanding at September 30, 1998 totalled approximately
$53,839,600.
 
8. COMMON AND PREFERRED STOCK
 
  The Company is authorized to issue two classes of capital stock: common
stock and preferred stock (each have a par value of $1.00 per share). The
preferred stock may be issued in one or more series. The number of shares to
be included in a series, as well as each series' designation, relative powers,
dividend and other preferences, rights and qualifications, redemption
provisions and restrictions are to be fixed by the Company's Board of
Directors at the time such series are issued. Except as may be provided by the
Board of Directors in a preferred stock designation, or otherwise provided for
by statute, the holders of the Company's common stock have the exclusive right
to vote for the election of Directors and all other matters requiring
stockholder action. The holders of the Company's common stock are entitled to
dividends if and when declared by the Board of Directors from whatever assets
are legally available for that purpose.
 
  Pursuant to the Company's 1990 Stockholder Rights Plan, each outstanding
share of common stock has attached to it one stock purchase right (a "Right").
Each Right entitles the common stockholder to purchase, in certain
circumstances generally relating to a change in control of the Company, one
two-hundredth of a share of the Company's Series A Junior Participating
Cumulative Preferred Stock, par value $1.00 per share (the "Series A Preferred
Stock") at the exercise price of $90 per share, subject to adjustment.
Alternatively, the Right holder may purchase common stock of the Company
having a market value equal to two times the exercise price, or may purchase
shares of common stock of the acquiring corporation having a market value
equal to two times the exercise price.
 
  The Series A Preferred Stock confers to its holders rights as to dividends,
voting and liquidation which are in preference to common stockholders. The
Rights are nonvoting, are not presently exercisable and currently trade in
tandem with the common shares. The Rights may be redeemed at $0.01 per Right
by the Company in accordance with the Rights Plan. The Rights will expire on
December 20, 2000, unless earlier exchanged or redeemed.

10. SUBSEQUENT EVENT
 
  In December 1998, the Company signed an agreement and plan of merger with
the Sverdrup Corporation ("Sverdrup"). The agreement is subject to the
approval of the shareholders of Sverdrup, as well as the expiration or
termination of the Hart-Scott-Rodino Act waiting period. As a result of the
transactions contemplated in the merger agreement, Sverdrup Corporation will
become, upon closing of the transaction, a wholly-owned subsidiary of the
Company. Total consideration to be paid by the Company at closing will be
approximately $198,000,000. The Company intends to finance the merger price
through a combination of bank borrowings (under a new, long-term revolving
credit facility) and internal funds. The merger agreement also requires the
Company to pay additional cash consideration to the former shareholders of
Sverdrup at each of the first three anniversaries of closing if the stock
price of the Company exceeds certain minimum prices as specified in the merger
agreement. These future payments in total cannot exceed $31,000,000. The
merger will be accounted for as a purchase, and is expected to be completed
early in the second quarter of fiscal 1999.

                             INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Jacobs Engineering Group Inc.
 
  We have audited the accompanying consolidated balance sheets of Jacobs
Engineering Group Inc. and subsidiaries as of September 30, 1998 and 1997, and
the related consolidated statements of income, stockholders' equity, and cash
flows for each of the three years in the period ended September 30, 1998.
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 Jacobs
Engineering Group Inc. and subsidiaries at September 30, 1998 and 1997, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended September 30, 1998, in conformity with
generally accepted accounting principles.

             MANAGEMENT'S RESPONSIBILITIES FOR FINANCIAL REPORTING
 
  The consolidated financial statements and other information included in this
appendix to this proxy statement have been prepared by management, which is
responsible for their fairness, integrity, and objectivity. The consolidated
financial statements have been prepared in accordance with generally accepted
accounting principles applied on a basis consistent with prior years and
contain some amounts that are based upon management's best estimates and
judgment. The other financial information contained in this appendix has been
prepared in a manner consistent with the preparation of the financial
statements.
 
  In meeting its responsibility for the fair presentation of the Company's
financial statements, management necessarily relies on the Company's system of
internal accounting controls. This system is designed to provide reasonable,
but not absolute, assurance that assets are safeguarded and that transactions
are executed in accordance with management's instructions and are properly
recorded in the Company's books and records. The concept of reasonable
assurance is based on the recognition that in any system of internal controls,
there are certain inherent limitations and that the cost of such systems
should not exceed the benefits to be derived. We believe the Company's system
of internal accounting controls is cost-effective and provides reasonable
assurance that material errors and irregularities will be prevented, or
detected and corrected on a timely basis.
 
  The Company's consolidated financial statements have been audited by
independent auditors, whose report thereon was based on examinations conducted
in accordance with generally accepted auditing standards and is presented on
the preceding page. As part of their audit, the independent auditors perform a
review of the Company's system of internal accounting controls for the purpose
of determining the amount of reliance to place on those controls relative to
the audit tests they perform.
 
  The Company's Board of Directors, through its Audit Committee which is
composed entirely of nonemployee directors, meets regularly with both
management and the independent auditors to review the Company's financial
results and to ensure that both management and the independent auditors are
properly performing their respective functions.
