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 throughout the United States, Europe and India.

     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.  Such 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.  The following is a description of some of the more
significant acquisitions made by the Company over the past five years.  It is
not intended to list in detail all acquisitions made, but rather it is meant to
assist in the understanding of the general development of the Company's business
over the past five years (the year of acquisition is shown parenthetically):

     Humphreys & Glasgow ("H&G")      This was one of the Company's earlier
                                      acquisitions outside the United States.
                                      H&G provides broad-based process
                                      engineering and design skills, and a large
                                      client base in the chemicals,
                                      pharmaceuticals and petroleum industries,
                                      among others. (Fiscal 1993)

     The Wolder Group                 This acquisition broadened the Company's
                                      geographic presence for its clients in the
                                      petroleum industry. It also helped to
                                      diversify the Company's west coast
                                      operations. (Fiscal 1993)

     The Sigel Group                  This acquisition expanded the Company's
                                      technical and project management
                                      capabilities in the biotechnology /
                                      pharmaceuticals industries. (Fiscal 1993)

     CRS Sirrine & CRSS Constructors  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), and enhanced the
                                      Company's capabilities for its clients in
                                      both the semiconductor and buildings &
                                      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. (Fiscal 1994)

      HGC India                       From 1993, when the Company acquired H&G,
                                      to 1997 HGC India was an unconsolidated
                                      affiliate of the Company. This acquisition
                                      gave the Company access to the Southern
                                      Asia market, expanded the Company's client
                                      base, added professional staff, and
                                      enhanced its existing engineering
                                      capabilities.
                                      (Fiscal 1997)

     The Serete Group                 This acquisition provided the Company with
                                      an established presence on continental
                                      Europe. 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.
                                      (Fiscal 1997)

     In addition to the particular advantages described above, these
acquisitions, along with all other acquisitions made by the Company over the
past five years, 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.

     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, 1997 (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 environmental area of the Company's business (see
"Industry Groups and Markets - Federal Programs", below), the Company employs
all of the requisite engineering, scientific, public health and related skills
to consult, investigate, study, manage and provide remedial engineering for

                                    Page 2
<PAGE>
 
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.

     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 significantly reduce new plant costs.  In the environmental area,
recent contract awards from clients in the public sector require the Company to
provide environmental remedial construction services.

     The Company's field construction activities are focused primarily on those
construction projects for which the Company has performed the engineering and
design work.  By focusing its construction efforts on such projects, the Company
avoids 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 

                                    Page 3
<PAGE>
 
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.

INDUSTRY GROUPS AND MARKETS
- ---------------------------
     The Company has chosen to focus its efforts on the following industry
groups and markets: chemicals; petroleum; semiconductor; buildings and
infrastructure; pulp and paper; pharmaceuticals and biotechnology; and U.S.
federal programs.  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, 1997 (in thousands of dollars):

</TABLE>

     In the area of federal programs, the Company historically has provided
primarily environmental restoration, engineering and consulting services.
However, several of the more recent contracts awarded to the Company are for
engineering, construction and project management services for the remediation of
sites contaminated with hazardous wastes.  Maintenance services are provided
primarily to the chemicals and petroleum industries.

     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 high-pressure polymer processes for the
production of bulk chemicals, to low-pressure, multi-product processes for the

                                    Page 4
<PAGE>
 
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, advance polymer technologies, as well as many specialty
chemicals.

     Semiconductor
     -------------
     The Company provides engineering, procurement, construction, and
construction management services to its clients in the semiconductor industry.
Typical projects in this industry include 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.

     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
feasibility and multi-client studies. Although the Company's revenues
historically have related primarily to projects associated with petroleum
refining, more recent contract awards are for services to pipeline companies and
companies in businesses upstream of refiners.

     Since 1993, many of the Company's contract awards in the petroleum area
have been for plants producing oxygenates and other high-octane fuel blending
components for gasoline (such components are required by the Clean Air Act of
1990 in reformulated gasolines in order to reduce the emissions of unburned
hydrocarbons and carbon monoxide from automobiles), as well as plants that
hydrotreat various fuel fractions to reduce the sulfur content of blended
products.  The Company has completed several major projects to design, engineer,
procure and construct methyl tertiary butyl ether ("MTBE") units and tertiary
amyl butyl ether ("TAME") units for a number of major refiners at facilities
located throughout the United States.  The Company has also utilized its off-
site construction capabilities in the construction and installation of these
units.  The use of off-site construction can help decongest the construction
site and allow for parallel construction to proceed simultaneously with the
modular activity.

     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 oil
refiners for 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 with clients.  Over the past several
years, the Company has entered into evergreen engineering services contracts
with several clients.  Such agreements have been both site-specific and national
in scope.  Often, these alliances provide the Company with opportunities to
expand its services to include fully-integrated engineering, procurement,
construction and construction management services.

     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 in the United States of environmental restoration, engineering
and consulting services, including hazardous waste management and site cleanup
and closure.  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 


                                    Page 5
<PAGE>
 
government agencies including the U.S. Department of Energy ("DOE"), the
Department of Defense ("DOD") and the U.S. Environmental Protection Agency
("USEPA").

     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.

     Typical projects for U.S. government agencies include 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 relate 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.  More recently, the Company has been awarded multi-year contracts 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).  The Alaska
TERC is a multi-year program to provide engineering and site cleanup services
throughout that state.  The Company also provides project management services
over site cleanup activities at various government installations, as well as
detailed scientific and support services, groundwater restoration management and
action plans, and services relating to the decommissioning of nuclear weapons
production and other defense facilities.

     Buildings and Infrastructure
     ----------------------------
       Buildings and infrastructure refers to those contracts requiring the
Company to provide 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.  Typical projects include civic centers, correctional facilities,
health care facilities and transportation systems, as well as multi-purpose
buildings for industrial, commercial and government clients.

     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.

     As with clients in the petroleum industry, the Company has established
formal partnering arrangements with certain clients in the pulp and paper
industry.  Such arrangements provide for the delivery of on-site engineering
services, and often expand to include procurement, construction and construction
management services.

     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.

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, 1993, 1994, 1995, 1996 and 1997, revenues
from agencies of the U.S. federal government accounted for 14.1%, 15.4%, 11.4%,
8.7% and 12.0%, 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 separate 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 1993 or 1996.

FOREIGN OPERATIONS
- ------------------
     For the years ended September 30, 1993, 1994, 1995, 1996 and 1997, revenues
from the Company's international operations were approximately 10.8%, 5.6%,
5.4%, 10.3% and 23.5%, respectively, of total revenues.  For fiscal years 1993
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.

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; guaranteed maximum price and fixed-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, 1997:

<TABLE>
<CAPTION>
 
                                 1993    1994    1995    1996    1997

</TABLE>

                                    Page 7
<PAGE>
 
     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, 1993, 1994, 1995, 1996
and 1997 (in millions):

                     1993         1994        1995        1996       1997
                  ----------   ----------  ----------  ---------- ---------- 
                    $610.7       $629.0     $1,001.3    $1,019.5    $919.6

     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.

     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.

     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 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.

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 regions in which the Company is located.
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. 


                                    Page 8
<PAGE>
 
Kellogg, Parsons Co., Brown & Root, Inc., and John Brown. In the semiconductor
industry, the Company's principal competitor is Industrial Design Corporation.
In the area of pulp and paper, the Company's principal competitors include BE&K,
Brown & Root, and Rust International. 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 other specialized companies such as IT
Corporation, ICF Kaiser and Roy F. Weston, Inc.

Employees
- ---------
     At September 30, 1997, the Company had approximately 9,570 full-time
employees.  Additionally, as of September 30, 1997, there were approximately
6,300 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.

     In addition to these properties, the Company leases smaller, project
offices located throughout the United States and, to a certain extent, France.
The Company maintains sales offices at many of its principal locations. The
Company has equipment yards located in Houston, Texas and Baton Rouge,
Louisiana. The majority of the Company's offices are leased. The Company also
rents a portion of its construction equipment on a short-term basis.

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
construction 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.

                                  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.

 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 last year. The
increase in engineering services activity was due in part to certain
acquisitions the Company completed in 1997, and in part to internal growth.
 
  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.
 
  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 last
year 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 (the costs of which are included in both revenues and
costs).
 
                                      A-3

  As a percent of revenues, direct costs of contracts was 86.9 percent in
1997, versus 88.4 percent in 1996. 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 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 selling, general and administrative ("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 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 (defined as total revenues, less direct costs
of contracts, and S,G & A expenses) 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.
 
 1996 Compared to 1995
 
  Consolidated revenues increased 4.4 percent from 1995 to 1996. This increase
was comprised of a 6.7 percent increase in engineering services revenues and
an overall 3.2 percent increase in field services revenues.
 
  With respect to the Company's field services activity in 1996, and while
revenues from construction activities increased 5.0 percent from 1995,
revenues from maintenance activities were down 2.9 percent from the prior
year. Construction revenues increased during 1996 in spite of the fact the
Company completed construction on two large projects during the year (one for
a client in the petroleum industry, and another for a client in the
semiconductor industry), and it substantially completed construction on a
third major project (for a client in the buildings and infrastructure industry
group). Also contributing to the increase in field services revenues from 1995
to 1996 was an $18.2 million increase in subcontract and procurement activity.
 
  As a percent of revenues, direct costs of contracts was 88.4 percent in
1996, versus 89.0 percent in 1995. In general, the decrease in this percentage
relationship from 1995 to 1996 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 $143.5 million in 1996; this was
only $6.9 million, or 5.0 percent, more than the 1995 amount. The increase in
S,G & A expenses corresponds to the increase in the overall business volume
discussed above, and reflects the Company's continuing efforts to control such
expenses throughout its operations.
 
  The Company's operating profit totalled $64.6 million in 1996; this was
$11.9 million more than the 1995 amount. In general, the improvement was due
to increased business volume, combined with higher margin rates for the
Company's services.
 
  Interest income, net totalled $1.4 million in 1996; this was $1.1 million
more than the 1995 amount. The increase in net interest income was due
primarily to higher levels of cash invested during 1996 as compared to 1995,
combined with slightly better rates of interest earned on such investments.

<PAGE>
 
  Other income, net totalled $0.8 million in 1996; this was $0.4 million more
than the 1995 amount. The increase in other income, net was due primarily to
higher gains from sales of marketable securities and other assets in 1996 as
compared to 1995.
 
BACKLOG
 
  The following table summarizes the Company's total backlog at September 30,
1997, 1996, and 1995 (in millions):

</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, 1997 included approximately $923.0 million of
contracts for work to be performed either directly or indirectly for agencies
of the U.S. federal government. This compares to approximately $1.0 billion
and $1.1 billion of federal backlog at September 30, 1996 and 1995,
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).
 
  Net of work-off, the Company's backlog increased $125.2 million from 1995 to
1996, and it increased by $299.8 million from 1996 to 1997. Most of the 1996
increase was due to new awards from clients in the petroleum and chemicals
industries, combined with scope expansions on a project in the semiconductor
industry. A significant portion of the 1997 increase was also due to new
awards in the petroleum and chemicals industries, combined with backlog
acquired in conjunction with several acquisitions made by the Company in 1997.
 
  Of total backlog at September 30, 1997, the Company estimates that
approximately 40 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.
 
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
 
                                      A-5
<PAGE>
 
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 decreased $6.9 million during 1997.
This compares to a net increase of $23.7 million in 1996, and a net decrease
of $6.5 million during 1995. The current year decrease was due primarily to
cash used in investing activities ($69.5 million), offset in part by cash
provided by operations ($43.9 million) and financing activities ($20.3
million).
 
  Operations provided $43.9 million of cash and cash equivalents in 1997. This
compares to net contributions of cash of $54.3 million in 1996 and $32.0
million in 1995. The $10.4 million decrease in cash provided by operations
from 1996 to 1997 occurred in spite of higher net income ($6.5 million) and
depreciation and amortization expense ($1.5 million), which was offset in part
primarily by the timing of cash receipts and payments relating to receivables
and prepaid expenses, and trade payables, customer advances and accrued
liabilities, respectively ($19.0 million).
 
  The Company's investing activities used $69.5 million of cash and cash
equivalents in 1997. This compares to net uses of cash of $40.0 million in
1996 and $45.0 million in 1995. The $29.5 million increase in cash used in
investing activities from 1996 to 1997 was due primarily to an increase in
property and equipment additions ($11.3 million), and an increase in additions
to other, long-term assets ($14.1 million). Both the increase in fixed asset
additions and the increase in additions to other, long-term assets relate
primarily to two businesses the Company acquired during 1997.
 
  During 1997, cash used to purchase and make investments decreased $17.2
million as compared to 1996, while cash used to purchase marketable securities
increased $20.0 million. Included in the amount of cash used in 1996 to
purchase and make investments was the Company's purchase of 49 percent
interests in various engineering and construction companies comprising the
Serete Group (which is headquartered in France). No similar investment
transactions occurred in 1997 (although the Company did complete the purchase
of the remaining interests in most of the members of the Serete Group in 1997;
however, the net cash used for this transaction is included in the line
"Acquisition of businesses, net of cash acquired"). Cash used in 1997 to
purchase marketable securities related to a $20.0 million deposit with a U.S.
bank made by the Company under a managed investment program. 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.
 
  The Company's financing activities provided $20.3 million of cash and cash
equivalents in 1997. This compares to a net contribution of cash of $9.6
million in 1996 and $6.6 million in 1995. The increase in cash provided from
financing activities from 1996 to 1997 was due primarily to higher cash flows
from the issuance of stock to employees ($2.7 million), and increased
borrowings of long-term bank debt ($2.5 million). Also contributing to the
increase in cash provided by financing activities in 1997 as compared to 1996
was the use in 1996 of $15.7 million to repay short-term bank debt; no similar
use occurred in 1997. Offsetting these sources of additional financing funds
in 1997 as compared to 1996 was an increase in the amount of cash used to
purchase treasury stock ($8.5 million). The Company's stock buy-back program
was initiated during the second half of 1996.

  The Company believes it has adequate capital resources available to fund
operations in 1998 and beyond. The Company's consolidated working capital
position totalled $178.2 million at September 30, 1997; this was $22.6 million
more than the comparable 1996 amount. At September 30, 1997, the Company had a
total of $48.0 million available under all of its short-term bank credit
facilities, against which $1.3 million was outstanding in the form of direct
borrowings.
 
COSTS ASSOCIATED WITH "YEAR 2000 ISSUE"
 
  The Company continues to evaluate what effects, if any, Year 2000 issues may
have on its operations. At present, the Company does not believe such issues
will have any material adverse effect on its consolidated financial
statements.
 
EFFECT OF RECENTLY-ISSUED ACCOUNTING STANDARDS
 
  In February 1997, the Financial Accounting Standards Board adopted Statement
of Financial Accounting Standards No. 128--Earnings per Share ("SFAS No.
128"). SFAS No. 128 simplifies the standards for calculating earnings per
share, and makes them comparable to international accounting standards. SFAS
128 will be effective for the Company beginning with the first fiscal quarter
of 1998. The Company does not believe the adoption of SFAS 128 will have a
material effect on its consolidated results of operations.

                  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 1996
balances in the accompanying consolidated balance sheet have been reclassified
to conform to the 1997 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, 1997, 1996, and 1995 was as
follows:
 
<TABLE>

                                                                  1997  1996  1995
                                                                  ----  ----  ----
   <S>                                                            <C>   <C>   <C>

   Guaranteed maximum............................................   2     2     1
   Fixed-price...................................................  16    16    11
</TABLE>
 
  For the years ended September 30, 1997, 1996, and 1995, projects with or for
the benefit of agencies of the U.S. federal government accounted for 12.0
percent, 8.7 percent and 11.4 percent, respectively, of total revenues. Within
the private sector, one client accounted for 15.3 percent of total revenues in
1997, and a different client accounted for 13.1 percent of revenues in 1995.
No single private-sector client accounted for 10 percent or more of total
revenues in 1996.
 
 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.

 Foreign Operations
 
  In 1995, 1996, and for most of 1997, the Company's operations outside of the
United States were conducted primarily through its offices in the U.K. and
Ireland. Then in 1997, as more fully discussed in Note 2 below, the Company
acquired controlling interests in various engineering and construction
companies located in India, France, Spain, Italy and Santiago, Chile. The
following table summarizes certain financial information of the Company for
geographic areas outside the United States (in thousands):

    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 Chile in 1997 were not material.
 
 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, 1997 and 1996 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, 1997 and
1996 totalled $114,000 and $621,600, respectively.

</TABLE>
 
  Included in marketable securities at September 30, 1997 was a $20,000,000
deposit with a U.S. bank made under a managed investment program. 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, 1997 and 1996 were unbilled amounts
of $82,972,400 and $50,770,100, 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, 1997 and 1996 were contract retentions totaling
$5,708,100 and $12,616,000, 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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  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.
 
 Other Noncurrent Assets
 
  Goodwill represents the costs in excess of the fair values of the net assets
of acquired companies and is amortized against earnings using the straight-
line method over periods not exceeding 40 years. Goodwill is shown in the
accompanying consolidated balance sheets net of accumulated amortization of
$6,908,000 and $4,997,700 at September 30, 1997 and 1996, respectively.
 
  Other noncurrent assets consisted of the following at September 30, 1997 and

  In 1996, the Company purchased 49 percent interests in various engineering
and construction companies comprising the Serete Group (which is headquartered
in France). The purchase price was $18,881,300. In 1997, the Company purchased
substantially all of the remaining interests of most of the entities in the
Serete Group (see Note 2., below). Prior to the 1997 transaction, the Company
had been accounting for its investment in the Serete Group using the equity
method.
 
 Net Income Per Share
 
  Net income per share has been computed in accordance with Accounting
Principles Board ("APB") Opinion No. 15 -- Earnings per Share. Accordingly,
net income per share has been computed based on the weighted average number of
shares of common stock and, if dilutive, common stock equivalents outstanding
as follows (in thousands):

  The Company will adopt the provisions of Statement of Financial Accounting
Standards ("SFAS") No. 128 (also titled "Earnings per Share") beginning with
the first fiscal quarter of 1998.
 
 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.
 
  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.
 
 Deferred Gains on Real Estate Transactions
 
  In 1983, the Company entered into a real estate transaction which resulted
in a gain totaling $12,299,800. Since the transaction involved a long-term
lease agreement, the gain was deferred and is being amortized ratably into
income over the lease term (which ends December 31, 1997).
 
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 acquired for cash a 51
percent controlling interest 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 most of the entities in the Serete
Group.
 
  The sum of the individual purchase prices totalled $29,781,500. Each of
these acquisitions have 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 initial purchase price allocations, which may be adjusted further,
resulted in goodwill of approximately $36,054,000. 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, 1997, the Company had approximately $47,978,000 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 1998.

  The mortgage loan was incurred in connection with the purchase of the
Company's real property located in Dublin, Ireland, and is secured by the
property. The loan bears interest at variable rates for selected periods from
one to twelve months based on the Dublin Interbank Offered Rate, and is
payable at the end of each selected period. The interest rate in effect at
September 30, 1997 was 6.86 percent.
 
  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, 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.
 
  Interest expense for the years ended September 30, 1997, 1996, and 1995 was
$2,958,700, $2,777,400 and $2,216,000, respectively, and has been included
with interest income in the accompanying consolidated statements of income.
Interest payments made during each of these years totalled $1,801,500,
$2,552,300 and $2,044,500, 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, 1997, 1996, and 1995 follows:

the 1989 ESPP.
 
 Stock Option Plan
 
  The Company has an incentive stock plan (the "1981 Plan") which provides for
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, 1997, there were 3,195,204
shares of common stock reserved for issuance under the 1981 Plan.

  Options outstanding at September 30, 1997 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.
 
  The Company issued 5,500, 9,000 and 61,000 shares of restricted stock under
the 1981 Plan during each of the years ended September 30, 1997, 1996, and
1995, respectively. 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 ($329,900,
$285,800 and $67,500 of compensation expense was recognized in 1997, 1996 and
1995, 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 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):

</TABLE>
 
    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, 1997, 1996, and 1995, Company
contributions to these plans totalled $8,710,500, $8,000,100 and $7,719,400,
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, 1997, 1996, and 1995 were $1,672,600, $1,781,200 and $1,601,000,
respectively. Included in other deferred liabilities in the accompanying
consolidated balance sheets at September 30, 1997 and 1996 was $23,446,800 and
$19,092,700, 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 $2,694,700, $3,538,900 and $5,044,400
for the years ended September 30, 1997, 1996, and 1995, 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, 1997 and 1996 (in thousands):

  The significant actuarial assumptions used in determining the funded status
of the plan were as follows: weighted average discount rate -- 8 percent;
weighted average rate of increase in compensation -- 6 percent; and, weighted
average rate of return on pension assets -- 8.5 percent. At September 30,
1997, 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.
 
6. PROVISION FOR INCOME TAXES
 
  The Company accounts for income taxes in accordance with SFAS No. 109 --
 Accounting for Income Taxes. Accordingly, deferred tax assets and liabilities
are determined based on the differences between the financial reporting and
tax bases of assets and liabilities, and are measured using the enacted tax
rates and laws that will be in effect when the differences are expected to
reverse.
 
  Consolidated income tax expense for the years ended September 30, 1997,
1996, and 1995 consisted of the following (in thousands):

  For the years ended September 30, 1997, 1996, and 1995, consolidated income
before income taxes included $16,029,300, $4,707,100 and $380,200,

permanently reinvested (the amount of such profits expected to be permanently
reinvested totalled $7,830,800 at September 30, 1997). Should these earnings
be repatriated, approximately $2,070,700 of income taxes would be payable.

  Rent expense for the years ended September 30, 1997, 1996, and 1995 was
approximately $29,978,000, $27,190,200 and $24,601,700, respectively, and was
offset by sublease income of approximately $2,780,000, $2,313,500 and
$1,326,700, respectively.
 
  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.
 
  The Company has entered into an employment agreement expiring September 30,
2002 with the Chairman of its Board of Directors. The agreement provides for
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
construction 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, 1997 totalled approximately
$62,854,000.

8. COMMON AND PREFERRED STOCK
 
  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.

                             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, 1997 and 1996, and
the related consolidated statements of income, stockholders' equity, and cash
flows for each of the three years in the period ended September 30, 1997.
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, 1997 and 1996, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended September 30, 1997, in conformity with
generally accepted accounting principles.

             MANAGEMENT'S RESPONSIBILITIES FOR FINANCIAL REPORTING
 
  The consolidated financial statements and other information included in this
annual report 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 financial
information contained elsewhere in this report 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.
