                               PROSPECTUS SUMMARY

The following is a summary of the more detailed information and financial
statements included in this prospectus. Because this summary only highlights
the most significant aspects of our business and this offering and does not
contain all of the information that is important to you, you should read the
entire prospectus carefully, including the risk factors and financial
statements.

We are an engineering, consulting and technical services firm located in the
western United States. We specialize in:

  .   planning, engineering, designing, permitting and other services for a
      wide range of residential, commercial and recreational real estate
      development and public works projects and for wireless
      telecommunications networks

  .   mechanical, electrical, chemical and other industrial engineering
      services to design and improve the efficiency and reliability of
      automated and manufacturing processes, production lines and fire
      protection systems

We believe that our success is due to a number of factors, including:

  .   our well-established reputation for providing timely and high quality
      services to our clients

  .   our experience and relationships with permitting and planning
      authorities at many governmental levels

  .   our experienced professional staff

  .   our ability to provide our clients with a full range of services, which
      many of our competitors are unable to provide, resulting in both cost
      and time savings to our clients as they no longer need to manage
      multiple providers

  .   our ability to provide the increased scope of services that may arise
      beyond the original contract, often resulting in the fees paid to us
      significantly exceeding the original contract

The geographic regions we serve in the western United States are undergoing
economic expansion. Historical and projected growth in population, personal
income and employment are all combining to provide a robust economic
environment in which our services are necessary. As an example, we believe that
southern California residential real estate development is in the beginning of
the third year of what we believe has historically been a seven to ten year
upturn for new home building.

Our business strategy includes the following:

  .   maintain the high quality of our services

  .   continue to recruit and retain highly qualified personnel

  .   expand the geographic scope of our operations in the western United
      States

  .   expand our service offerings and the industries we serve

  .   continue to acquire and effectively integrate new business operations

                                       4

We have provided engineering, consulting and technical services for over 16
years. Since late 1997, we have made three acquisitions that enabled us to
expand our service offerings to include process engineering design, mechanical,
chemical and electrical engineering, environmental waste processing systems
design, petrochemical design, services relating to flood control and expanded
water resources engineering, environmental permitting, and biological surveys
and studies. In addition, we have expanded geographically into central and
northern California and Utah, and we intend to continue to expand throughout
the western United States to better service our clients.

We employ 461 professionals in our eight offices located in three states. Our
clients include major national and regional real estate development firms
including The Irvine Company, Kaufman & Broad Home Corporation and Pulte Home
Corporation. We also serve architects, water districts, federal, state and
local governments, including Orange County Transportation Authority,
Metropolitan Water District of Southern California and Central Utah Water
Conservation District. In addition, we serve cellular telephone service
providers, universities and manufacturers of a wide variety of products,
including Dow Chemical Company, Toyota Motor Company and Enron Energy Services.

Our principal executive offices are located at 2955 Red Hill Avenue, Costa
Mesa, California 92626, and our telephone number is (714) 540-0800. Our
Internet address is http://www.keithco.com. Information contained on our web
site should not be considered to be part of this prospectus.

                                  RISK FACTORS

The following discussion summarizes material risks which you should carefully
consider before you decide to buy our common stock. Additional risks and
uncertainties may also adversely impact our business operations. If any of the
following risks actually occur, our business, financial condition or results of
operations would likely suffer. The trading price of our common stock could
then decline, and you may lose all or part of the money you paid to buy our
common stock.

Our operations and financial condition may be materially adversely affected by
a downturn in the real estate market, which is highly cyclical in nature

A downturn in the real estate market, which is highly cyclical in nature, may
cause us to experience cash flow difficulties and to sustain substantial
operating losses. We estimate that during 1998, 80% of our services were
rendered in connection with commercial and residential real estate development
projects.

Our business, financial condition and results of operations may also be
adversely affected by conditions that impact the real estate market in general,
including, among other things:

  .   changes in national economic conditions, changes in local market
      conditions due to changes in general or local economic conditions and
      neighborhood characteristics

  .   changes in interest rates and in the availability, cost and terms of
      financing

  .   the impact of present or future environmental legislation and
      compliance with environmental laws and other regulatory requirements

  .   changes in growth in employment

  .   changes in real estate tax rates and assessments and other operating
      expenses

  .   adverse changes in governmental rules and fiscal policies

  .   adverse changes in zoning and other land use laws

  .   earthquakes and other natural disasters, which can cause uninsured
      losses, and other factors which are beyond our control

Our business may be materially adversely affected by changes in the real estate
market or local economy in southern California

Adverse economic and other conditions affecting the southern California real
estate market or local economy, may have a material adverse effect on our
business, financial condition and results of operations. We estimate that
during 1998, 50% of our net revenue was derived from services rendered in
connection with commercial and residential real estate developments in southern
California. From 1991 to 1996, our operations and financial condition were
materially adversely impacted during the real estate market downturn in
southern California, and we experienced cash flow difficulties and substantial
operating losses.

Qualified professionals are in high demand, may be difficult for us to attract
and retain, and may become competitors of ours in the future

If we are unable to recruit and retain a significant number of quality
professionals, our ability to generate revenue may decrease and our gross
revenues could decline or may not grow as rapidly as we expect. We derive our
revenues almost exclusively from services performed by our professionals.
Qualified professionals are in great demand and are likely to remain a limited
resource for the foreseeable future. There is significant competition for
employees with the requisite skills from major and boutique consulting,
engineering, research and other professional service firms. We may not be able
to attract and retain a substantial majority of our existing or future
professionals for the long term. The loss of the services of, or the failure to
recruit, a significant number of professionals could adversely affect our
ability to secure and complete engagements and could have an adverse effect on
our business, financial condition and results of operations. In addition,
former employees might compete with us with respect to ongoing or potential
future projects.

The loss of any of the significant clients on whom we rely could adversely
affect our operating results

We derive a significant portion of our revenue and profits from a relatively
limited number of clients. For example, net revenue from our five most
significant clients accounted for approximately 21% of our total net revenue
for the year ended December 31, 1998. There can be no assurance that any of our
most significant clients will continue to engage us for additional projects or
will do so at the same revenue levels. In addition, the level of our services
required by a significant client may diminish over the life of its relationship
with us, and we may not be successful in establishing relationships with new
clients as this occurs.

The types of contracts under which we perform services impose risks to our
business

A majority of the contracts under which we perform our services require us to
bear unforeseen risks which could materially and adversely impact our business,
financial condition and results of operations.

In fiscal 1998, approximately 54%, 29% and 17% of our net revenue was derived
from fixed-price, time-and-materials with "not to exceed" provisions and time-
and-materials contracts, respectively.

Fixed-price contracts and time-and-materials contracts with "not to exceed"
provisions protect clients but expose us to a greater number of risks than
time-and-materials contracts. These risks include:

  .   underestimation of costs

  .   problems with new technologies

  .   unforeseen costs or difficulties

                                       9
<PAGE>

  .   delays beyond our control

  .   economic and other changes that may occur during the contract period

Under fixed price contracts, we perform services under a contract at a
stipulated price. Under time-and-materials contracts, we are reimbursed for the
number of labor hours expended at an established hourly rate negotiated in the
contract, plus the cost of materials incurred. Under time-and-materials with
"not to exceed" provisions contracts, we are reimbursed similar to time-and-
materials contracts; however, there is a stated maximum dollar amount for the
services to be provided under the contract.

The market price of our stock may fluctuate due to changes in our revenue and
operating results

We experience seasonal and quarterly fluctuations in revenue and operating
results which may cause the market price of our stock to fluctuate. Our
business is affected by seasonal and quarterly variations due primarily to
weather.

A number of other factors contribute to the quarterly variations which we
experience, including:

  .   client engagements commenced and completed during a quarter

  .   seasonality

  .   the number of business days in a quarter

  .   the number of work days lost as a result of adverse weather conditions
      or delays caused by third parties

  .   employee hiring, billing and utilization rates

  .   the consummation of acquisitions

  .   the length of the sales cycle on new business

  .   the ability of clients to terminate engagements without penalty

  .   our ability to efficiently shift our employees from project to project

  .   the size and scope of assignments

  .   general economic conditions

In addition, because a portion of our expenses are relatively fixed,
significant variations in revenues or the number of days in a quarter can cause
fluctuations in operating results from quarter to quarter and could result in
losses.

                                       10

We may not be able to maintain or accelerate our current growth, effectively
manage our expanding operations or achieve planned growth on a timely or
profitable basis.

We have grown rapidly and intend to pursue further growth as part of our
business strategy. Our rapid growth has presented and will continue to present
numerous operational challenges, including the management of an expanding array
of engineering, consulting and technical services, the assimilation of
financial reporting systems, increased pressure on our senior management and
increased demand on our systems and internal controls. Our inability to manage
growth effectively and efficiently could materially and adversely affect our
business, financial condition and results of operations.

If we need to sell additional shares of common stock and/or incur additional
debt to finance future acquisitions, your stock ownership could be diluted

Our business strategy is to expand into new markets and enhance our position in
existing markets through the acquisition of complementary businesses. In order
to successfully complete targeted acquisitions, it may be necessary for us to
issue additional equity securities that could dilute your stock ownership. We
may also incur additional debt and amortize expenses related to goodwill and
other tangible assets if we acquire another company, and this could negatively
impact our results of operations.

Our existing shareholders will retain significant control over TKCI following
this offering

The concentration of ownership of our stock may have the effect of delaying or
preventing a change in control of us and may adversely affect the voting or
other rights of other holders of our common stock. Upon completion of this
offering, our directors and executive officers, their respective affiliates and
persons who are obligated to vote together as a group will beneficially own
2,494,988 shares of common stock, or approximately 48.98% of our outstanding
common stock. Of these shares, 1,533,704 shares, or approximately 30.31% of our
outstanding common stock, will be owned by Aram H. Keith and 509,444 shares, or
approximately 10.07% of our outstanding common stock, will be owned by Floyd S.
Reid, both of whom are obligated to vote as a group. Walter W. Cruttenden, III,
one of our directors, will own 418,137 shares or approximately 8.26% of our
outstanding common stock.

The book value of your common stock will be substantially diluted in this
offering and may be diluted in the future

The offering price for the shares of common stock in this offering is
substantially higher than the book value per share of our common stock.
Consequently, if you purchase shares of our common stock in this offering you
will incur immediate and substantial dilution. In addition, we may sell shares
in the future, which may cause further dilution.

If we issue shares of preferred stock, the rights of holders of common stock
will be subordinate to the rights of holders of preferred stock

The rights of the holders of our common stock will be subordinate to, and may
be adversely affected by, the rights of the holders of any preferred stock that
may be issued in the future.

                                       11
<PAGE>

The issuance of the preferred stock could have the effect of making it more
difficult for a third party to acquire a majority of our outstanding voting
stock. Our board of directors has the authority to issue up to 5,000,000 shares
of preferred stock and to determine the price, rights, preferences, privileges
and restrictions, including voting rights, of those shares without any vote or
action by the shareholders.

There has been no prior public market for our common stock and our stock price
will likely be volatile

Prior to this offering, there has been no public market for our common stock,
and the initial public offering price may bear no relationship to our book
value, earnings history or other established criteria of value or to the price
at which the common stock will trade after the offering. There can be no
assurance that an active public market for our common stock will develop or be
sustained after the offering.

These fluctuations could adversely affect the market price of our common stock.
We believe that in addition to the other factors discussed in this "Risk
Factors" section, the following factors could also cause the market price of
our common stock to fluctuate, perhaps substantially:

  .   quarterly fluctuations in our operating results

  .   loss of key personnel

  .   general conditions in the financial markets, the real estate market,
      the engineering, consulting and technical services market and the
      worldwide economy

  .   fluctuations in interest rates

  .   announcement and market acceptance of acquisitions

  .   our failure to meet securities analysts' expectations

  .   changes in accounting principles

  .   sales of common stock by existing shareholders or holders of options
      or warrants

  .   adverse circumstances affecting the introduction or market acceptance
      of new services offered by us

  .   announcements of key developments by competitors

                                       12

A large number of shares of our common stock will be eligible for future sale
and, if sold, these shares may create excess supply in the market causing our
stock price to decline

The possibility that a large number of shares of our common stock may be sold
after the offering, and may create excess supply in the market, could cause a
drop in the market price of our common stock and could impair our ability to
raise capital through the sale of equity securities. Upon completion of this
offering, 5,059,708 shares of our common stock and options to purchase an
estimated 851,389 shares of our common stock granted under our Amended and
Restated 1994 Stock Incentive Plan will be outstanding. We intend to register
on a registration statement on Form S-8, shortly after the closing of this
offering, all of the shares of common stock underlying the options then
outstanding or issuable under the Amended and Restated 1994 Stock Incentive
Plan. We may also issue up to 37,037 shares of our common stock to the former
shareholders of ESI and grant options to purchase up to 37,037 shares of our
common stock to the employees of ESI, including the former shareholders of ESI,
if ESI meets earnings targets and other conditions. We may also issue 148,148
shares of common stock in 2000 to former employees of Thompson-Hysell who will
become employees of ours. This amount may be adjusted upward or downward
depending on whether Thompson-Hysell meets earnings goals. Upon the acquisition
of Thompson-Hysell, we will reserve 37,037 shares of our common stock under our
Amended and Restated 1994 Stock Incentive Plan and will issue a warrant to
acquire 66,667 shares of TKCI common stock in relation to the acquisition of
substantially all of the assets and the assumption of substantially all of the
liabilities of Thompson-Hysell. We have also issued warrants to acquire 83,333
shares of TKCI common stock in connection with earlier acquisitions. The
1,500,000 shares sold in this offering, other than shares that may be purchased
by our affiliates, will be freely tradeable. Of the remaining 3,559,708 shares
held by existing shareholders, 603,148 shares will be eligible for sale in the
public market on the date of this prospectus in reliance on Rule 144(k). The
remaining 2,956,560 shares will be eligible for sale at various times after the
offering upon expiration of one-year holding periods and once the conditions to
sale under Rule 144 have been satisfied. In addition, the sale of shares held
by all of our shareholders and persons with rights to acquire our shares,
except some non-management employees and the former shareholders of John M.
Tettemer & Associates and ESI, is restricted by agreements in favor of the
representative of the underwriters. The shares of common stock that may be
issued in connection with our acquisition of Thompson-Hysell will be restricted
securities but will include the right to have these shares registered for
resale under the Securities Act of 1933.

If we are unable to successfully implement our acquisition strategy, current
expectations of our growth or operating results may not be met

Acquisitions, which are a part of our growth strategy, involve risks that could
cause our actual growth or operating results to differ from our expectations or
the expectations of security analysts. For example:

  .   We may not be able to identify suitable acquisition candidates or to
      acquire additional companies on favorable terms.

                                       13
<PAGE>

  .   We compete with others to acquire companies. We believe that this
      competition will increase and may result in decreased availability or
      increased prices for suitable acquisition candidates.

  .   We may not be able to obtain the necessary financing, on favorable
      terms or at all, to finance any of our potential acquisitions.

  .   We may ultimately fail to consummate an acquisition even if we
      announce that we plan to acquire a company.

  .   We may fail to integrate successfully or manage any acquired company
      due to differences in business backgrounds or corporate cultures.

  .   An acquired company may not perform as we expect.

  .   We may choose to acquire a company that is less profitable than us or
      has lower profit margins than ours.

  .   We may find it difficult to provide a consistent quality of service
      across our geographically diverse operations.

  .   If we fail to integrate successfully any acquired company, our
      reputation could be damaged, potentially making it more difficult to
      market our services or to acquire additional companies in the future.

  .   Our acquisition strategy may divert management's attention away from
      our primary service offerings, result in the loss of key clients
      and/or personnel and expose us to unanticipated liabilities.

Increased competition in the industries we serve may adversely affect our
business

The market for services in the engineering, consulting and technical services
industries is highly competitive and is based primarily on quality of service,
relative experience, staffing capabilities, reputation, geographic presence,
stability and price. These factors of competition are likely to increase in the
future. Many of our competitors have more personnel and greater financial,
technical and marketing resources than us. These competitors include many
larger consulting firms like TetraTech Inc. and URS Corporation. We can offer
no assurance that we will be able to compete successfully in the future with
these or other competitors.

The loss of Mr. Keith or any of our other key professionals could adversely
affect our business, including our ability to secure and complete engagements
and attract and retain employees

We do not have an employment agreement with, or maintain key man life insurance
on, Aram H. Keith. Our success is highly dependent upon the efforts, abilities,
business

                                       14
<PAGE>

generation capabilities and project execution of our officers, especially those
of Mr. Keith, our President and Chief Executive Officer. If we lose the
services of Mr. Keith or any other key employee we may be less likely to secure
or complete contracts and to attract and retain additional employees.

Our services may expose us to liability in excess of our current insurance
coverage

Our services involve significant risks of professional and other liabilities
which may substantially exceed the fees we derive from our services. Our
business activities could expose us to potential liability under various
environmental laws, including the Comprehensive Environmental Response,
Compensation and Liability Act of 1980. In addition, from time to time, we
assume liabilities as a result of entering into indemnification agreements. We
cannot predict the magnitude of these potential liabilities.

We currently maintain general liability insurance, with coverage in the amount
of $1.0 million per occurrence, subject to a $2.0 million annual limitation;
professional liability insurance, with $2.0 million in coverage; and insurance
policies that pay claims up to a $5.0 million limit when coverage under these
other policies is not enough. Claims may be made against us which exceed these
limits. We will be liable to pay these claims from our assets if the claims
exceed these policy limits. These policies are "claims made" policies. Thus,
only claims made during the term of the policy are covered. If we terminate our
policies and do not obtain retroactive coverage, we would be uninsured for
claims made after termination even if these claims are based on events or acts
that occurred during the term of the policy. Our insurance may not protect us
against liability because our policies typically have various exceptions to the
claims covered and also require us to assume some costs of the claim even
though a portion of the claim may be covered. In addition, if we expand into
new markets, we may not be able to obtain insurance coverage for these new
activities or, if insurance is obtained, the dollar amount of any liabilities
incurred could exceed our insurance coverage. A partially or completely
uninsured claim, if successful and of significant magnitude, could have a
material adverse effect on our business, financial condition and results of
operations.

The quality of our service and our ability to perform under some of our
contracts would be adversely affected if qualified subcontractors are
unavailable for us to engage

Under some of our contracts, we rely on the efforts and skills of
subcontractors for the performance of some of the tasks. The absence of
qualified subcontractors with whom we have a satisfactory relationship could
adversely affect the level of our service offerings. In 1998, subcontractor
costs comprised approximately 14% of our gross revenue.

Year 2000 issues could affect our business

Many existing computer programs use only two digits to identify the year in the
date field. These programs were designed and developed without considering the
impact of the upcoming change in the century. As a result, any computer
programs that have time-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in system failure or
miscalculations, causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities.

                                       15
<PAGE>

We are heavily dependent upon the proper functioning of our own computer and
data-dependent systems. This includes, but is not limited to, our
support/administrative and operational/production systems. Any failure or
malfunctioning on the part of these or other systems could harm our business in
ways that we currently do not know and cannot discern, quantify or otherwise
anticipate. In addition, if our key vendors experience Year 2000 compliance
issues, then our business could be harmed.

We may be unable to implement the upgrades necessary to resolve any significant
problems we discover in our testing efforts. Even if we do make these upgrades,
they may not be effective in addressing the problems identified. If required
upgrades are not completed in a timely manner or are not successful, our
business could be harmed.

There are risks associated with forward-looking statements made by us and
actual results may differ

This prospectus contains forward-looking statements, including, among others:

  .   the anticipated growth in the engineering, consulting and technical
      services industries

  .   anticipated trends in our financial condition and results of
      operations

  .   our ability to finance our working capital requirements

  .   our business strategy for expanding our presence in the engineering,
      consulting and technical services industry

  .   our ability to distinguish ourselves from our current and future
      competitors

When used in this prospectus, the words "anticipate," "believe," "estimate,"
"expect," "intend," "plan" and similar expressions as they relate to us are
intended to identify forward-looking statements. These forward-looking
statements are based on our current expectations and are affected by a number
of risks and uncertainties. In addition to the risks described elsewhere in
this "Risk Factors" discussion, important factors to consider in evaluating
such forward-looking statements include:

  .   the shortage of reliable market data regarding the engineering,
      consulting and technical services industry

  .   changes in external competitive market factors or in our internal
      budgeting process that might impact trends in our results of
      operations

  .   unanticipated working capital or other cash requirements

  .   changes in our business strategy or an inability to execute our
      strategy due to unanticipated changes in the engineering, consulting
      and technical services industry

  .   various other factors that may prevent us from competing successfully
      in the marketplace

In light of these risks and uncertainties, many of which are described in
greater detail elsewhere in this "Risk Factors" discussion, our actual results
may differ materially from any forward-looking statements contained in this
prospectus.

                                USE OF PROCEEDS

We estimate that we will receive net cash proceeds of $11,790,000 from the sale
of 1,500,000 shares of common stock offered by us after deducting estimated
underwriting discounts and unpaid offering expenses. We currently intend to use
the net proceeds of this offering to acquire substantially all of the assets
and assume substantially all of the liabilities of Thompson-Hysell, to repay,
in whole or in part, debt, notes payable and capital lease obligations, the
proceeds from which were used primarily for capital expenditures, and notes
payable to related parties, including accrued interest thereon, and for general
corporate purposes.

As of March 31, 1999, the debt, notes payable, capital lease obligations and
notes payable to related parties, including accrued interest thereon, expected
to be repaid is as follows:

</TABLE>

We intend to acquire substantially all of the assets of Thompson-Hysell for
cash of $3,333,333, a note payable of $1,333,333 and may issue 148,148 shares
of TKCI common stock in 2000 if earnings goals are met. We may also be required
to pay an additional $500,000 if specified financial targets are met and an
estimated $525,000 for income tax effects. If the underwriters exercise all or
a portion of their overallotment option, we will use the net proceeds for
general corporate purposes.

We intend to invest the remainder of the net proceeds in short-term, investment
grade, interest-bearing cash equivalents until they are used.

                                DIVIDEND POLICY

TKCI has not declared or paid any cash dividends on TKCI's capital stock in
either of the past two fiscal years and does not anticipate paying cash
dividends on its common stock in the foreseeable future. The payment of any
future dividends will be at the discretion of TKCI's board of directors and
will depend upon, among other things, future earnings, capital requirements and
the general financial condition of its business.

TKCI's credit agreement with Imperial Bank restricts the payment of dividends
without the bank's consent. We intend to repay most of our bank debt with the
proceeds of the offering and then to attempt to negotiate a new credit
agreement, although we anticipate that any new credit agreement will similarly
restrict our ability to pay dividends.

                           PRIOR S CORPORATION STATUS

Keith Engineering was a corporation originally affiliated with TKCI because of
common management and ownership, which then became a wholly-owned subsidiary of
and was later merged into TKCI. From 1988 until 1998, Keith Engineering was
treated as an S corporation for purposes of federal and state income taxes.
Accordingly, Keith Engineering had not been subject to regular federal income
tax and was subject to California income tax at a rate of 1.5% of its taxable
income. Each of the shareholders of Keith Engineering was required to include
his portion of the Keith Engineering taxable income or loss in his individual
income for state and federal income tax purposes. Effective August 1, 1998,
Keith Engineering became a wholly-owned subsidiary, and its S corporation
status terminated. As a result, it began being taxed as a C corporation and
became subject to regular federal and state income taxes. Keith Engineering was
merged into TKCI on November 30, 1998.

                                  ACQUISITION

On April 9, 1999, TKCI entered into an Asset Purchase Agreement with Thompson-
Hysell and its shareholders. We expect to close this acquisition concurrently
with this offering. Thompson-Hysell provides real estate services similar to
TKCI in central and northern California and Utah. The founding shareholders of
Thompson-Hysell, who will be employed by us after the acquisition, have been
providing engineering, consulting and technical services for 17 years.

Under the Asset Purchase Agreement, TKCI will acquire substantially all of the
assets of Thompson-Hysell, including the right to use its name, and will assume
substantially all of its liabilities. TKCI will pay a purchase price of: (a)
cash in the amount of $3,333,333; (b) a promissory note in the amount of
$1,333,333 payable in 2001; and (c) shares of common stock with a value equal
to $1,333,334 which may be issuable in 2000 if various conditions are met. The
purchase price may be adjusted upward or downward depending upon (a) financial
targets being met related to the assets acquired and liabilities assumed; (b)
earnings for the years ended December 31, 1999 and 2000; and (c) an adjustment
for income tax effects.

The purchase price was determined as a result of negotiations conducted between
our representatives and representatives of Thompson-Hysell, neither of which
groups are affiliated with the other.

As of March 31, 1999, the total amount of liabilities to be assumed was
approximately $1,041,000. The cash consideration payable of $3,333,333 is
payable at the closing. In addition, within approximately four months of the
closing, we may pay additional cash if the net book value of the assets
acquired less the liabilities assumed is more than $1,000,000, but no more than
$500,000 must be paid by us for this reason. If this net book value is less
than $1,000,000, the note payable will be reduced by that amount. We may also
be required to pay additional cash consideration within four months of the
closing of this offering as a result of differences between the estimated
income taxes payable by the Thompson-Hysell shareholders as a result of the
acquisition compared to the estimated income taxes payable by the Thompson-
Hysell shareholders if they had sold their stock.

                                       18
<PAGE>

The note payable will have initial principal payable of $1,333,333, will bear
interest at 10%, and can be decreased as described above. The principal amount
payable can also be decreased or increased $67.00 for each $100.00 by which
earnings before interest and taxes for the year ended December 31, 2000 is less
than or exceeds $2,160,000. If the earnings before interest and taxes for the
year ended December 31, 2000 is less than $2,160,000, the earnings before
interest and taxes for the year ended December 31, 1998 in excess of $1,500,000
(which we estimate to be $527,000) can be added to reduce the shortfall but not
to an extent that will cause an increase in the note.

We have also agreed to issue a number of shares of our common stock equal to
$1,333,334 divided by the initial public offering price in this offering. The
aggregate value of the shares issued may be reduced or increased $67.00 for
each $100.00 by which earnings before interest and taxes for the year ended
December 31, 1999 is less than or exceeds $1,800,000. We have agreed to
register these shares for resale under the Securities Act of 1933 within 180
days after issuance. If Thompson-Hysell experiences a net loss before interest
and taxes for the year ended December 31, 1999 in excess of approximately
$190,000, then we will not be required to issue any shares. We must issue
additional shares to the extent that the earnings before interest and taxes
exceeds $1,800,000, according to the formula described above, without
limitation. These shares must be issued within ten days of the filing with the
Securities and Exchange Commission of our Annual Report on Form 10-K.

For purposes of this prospectus, including the pro forma information, we have
assumed that an additional $500,000 will be payable because the net book value
target has been exceeded to that extent and that $525,000 will be payable for
income tax effects. We have excluded the effect of the 1999 earnings target on
our contingent obligation to issue shares of our common stock.

TKCI has also agreed to reserve 37,037 shares of its common stock for issuance
under stock options to be granted to those employees of Thompson-Hysell who
become employees of TKCI upon the consummation of this offering. All of the
shareholders of Thompson-Hysell will enter into five-year non-competition

                                    DILUTION

At March 31, 1999, TKCI had a net tangible book value of $(2,000) or $0.00 per
share of common stock. Net tangible book value per share represents total
tangible assets less our total liabilities divided by the total number of
shares of common stock outstanding. Without taking into account any changes in
net tangible book value after March 31, 1999 other than to give effect to our
sale of 1,500,000 shares of common stock, our net tangible book value at March
31, 1999 would have been $11,442,000 or $2.26 per share. This represents an
immediate decrease in the net tangible book value of $6.74 per share to new
investors. The following table illustrates this per share dilution:

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

The following discussion should be read in conjunction with the consolidated
financial statements of TKCI and its subsidiaries and the related notes and the
other financial information included elsewhere in this prospectus. This
discussion contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of any number of
factors, including those set forth under "Risk Factors" and elsewhere in this
prospectus. This Management's Discussion and Analysis of Financial Condition
and Results of Operations section describes the operations of TKCI and its
subsidiaries without giving effect to the acquisition of Thompson-Hysell.

Overview

The following discussion should be read in conjunction with "Selected Financial
Data" and our consolidated financial statements and the related notes, included
elsewhere in this prospectus, and includes the operations of TKCI and our
wholly-owned subsidiaries, including Keith Engineering. TKCI and Keith
Engineering have been under common management since the inception of TKCI in
1986. TKCI and Keith Engineering were under common control as a result of a
contemporaneous written agreement dated July 1992 between their majority
shareholders. This agreement provided for the shareholders to vote in concert
and thus the majority shareholders became a common control group. On August 1,
1998, TKCI was reorganized, so that Keith Engineering became a wholly-owned
subsidiary of TKCI. This reorganization was accounted for as a combination of
affiliated entities under common control in a manner similar to a pooling-of-
interests. Under this method, the assets, liabilities and equity were carried
over at their historical book values and the operations of TKCI and Keith
Engineering have been recorded on a combined historical basis. The combination
did not require any material adjustments to conform the accounting policies of
the separate entities. On November 30, 1998 Keith Engineering was merged with
and into TKCI.

In December 1997, TKCI purchased ESI and its wholly-owned subsidiary ESII,
Engineered Systems Integration, Inc., which was subsequently merged into ESI.
ESI provides consulting services related to process engineering design,
chemical engineering, electrical engineering, environmental waste processing
system design and petrochemical systems design. In August 1998, TKCI purchased
John M. Tettemer and Associates, which provides services relating to flood
control and drainage engineering, environmental permitting, and biological
surveys and studies. In April 1999, TKCI entered into an asset purchase
agreement with Thompson-Hysell, under which TKCI would acquire substantially
all of the assets and assume substantially all of the liabilities of Thompson-
Hysell. With the exception of the services provided by ESI, Thompson-Hysell
provides services similar to ours in central and northern California and Utah.
This acquisition will close concurrently with this offering and is expected to
increase our revenue, and, based upon Thompson-Hysell's historical results, we
anticipate that our gross margins after the acquisition will be positively
impacted.


                                       25

We derive most of our revenue from professional service activities. The
majority of these activities are billed under various types of contracts with
our clients, including fixed fee and time and material contracts. Most of our
time and material contracts have not-to-exceed provisions. Revenue is
recognized on the percentage of completion method of accounting based on the
proportion of actual direct contract costs incurred to total estimated direct
contract costs. We believe that costs incurred are the best available measure
of progress towards completion on the contracts. In the course of providing
services, we sometimes subcontract for various services. These costs are
included in billings to clients and, in accordance with industry practice, are
included in our gross revenue. Because subcontractor services can change
significantly from project to project, changes in gross revenue may not be
indicative of business trends. Accordingly, we also report net revenue, which
is gross revenue less subcontractor costs. Our revenues are generated from a
large number of relatively small contracts.

In 1998, an estimated 80% of our net revenue was derived from services rendered
in connection with commercial and residential real estate development projects.
The real estate market has historically experienced pronounced business cycles.
Our consolidated results of operations can be adversely impacted by downturns
in the real estate market. Based upon the number of building permits issued,
the last peak of the business cycle in the southern California real estate
market was in 1989 and the last trough was in 1996. We estimate that during
1998, 50% of our net revenue was derived from services rendered in connection
with commercial and residential real estate developments in southern
California. Consequently, adverse economic conditions affecting the southern
California economy could also have an adverse effect on our consolidated
results of operations. We anticipate that as we consummate acquisitions in the
future, the concentration of revenue from both real estate development and
southern California will decline.

Costs of revenue include labor, non-reimbursable subcontract costs, materials
and various direct and indirect overhead costs including rent, utilities and
depreciation. Direct labor employees work predominantly at our offices, or in
some cases at the clients job site. The number of direct labor employees
assigned to a contract will vary according to the size, complexity, duration
and demands of the project. Contract terminations, completions and scheduling
delays may result in periods when direct labor employees are not fully
utilized. As we continue to grow, we anticipate that we will continue to add
professional and administrative staff to support our growth. These
professionals are in great demand and are likely to remain a limited resource
for the foreseeable future. The significant competition for employees with the
required skills creates wage pressures on professional compensation. We attempt
to increase our billing rates to customers to compensate for wage increases,
however, there can be a lag before wage increases can be incorporated into our
existing contracts. Some expenses, primarily long term leases, are fixed and
cannot be adjusted in reaction to an economic downturn.

Selling, general, and administrative expenses consist primarily of corporate
costs related to finance and accounting, information technology, contract
proposal, executive salaries, provisions for doubtful accounts and other
indirect overhead costs.

Results of Operations

The following table sets forth historical and unaudited pro forma supplemental
consolidated operating results for each of the periods presented as a
percentage of net revenue. Pro forma amounts for these periods reflect
adjustments for provisions for federal and state income taxes as if we had been
taxed as a C corporation, at an assumed effective income tax rate of
approximately 42%. On August 1, 1998, in connection with our reorganization,
Keith Engineering converted from an S corporation to a C corporation.

Three Months Ended March 31, 1999 and March 31, 1998

Revenue. Net revenue for the three months ended March 31, 1999 was $9.0 million
compared to $6.0 million for the three months ended March 31, 1998, an increase
of $3.0 million, or 50%. Net revenue increased by $500,000 as a result of the
acquisition of John M. Tettemer & Associates in August 1998. The remaining net
revenue increase of $2.5 million resulted primarily from the overall
strengthening of the California and Nevada economies. Excluding the revenue
from the acquisition of John M. Tettemer & Associates, our net revenue for the
three months ended 1999 grew $2.5 million, or 42%, compared to the three months
ended March 31, 1998. Subcontractor costs, as a percentage of net revenue
declined to 11% for the three months ended March 31, 1999 as compared to 19%
for the three months ended March 31, 1998, resulting primarily from a $187,000
decrease in services for our primary wireless telecommunications contract,
which was substantially completed by the end of 1998.

Gross Profit. Gross profit for the three months ended March 31, 1999 was $3.1
million compared to $1.9 million for the three months ended March 31, 1998, an
increase of

                                       27
<PAGE>

$1.2 million, or 62%. Gross profit growth is attributable to both our internal
revenue increases as well as the acquisition of John M. Tettemer & Associates.
As a percentage of net revenue, gross profit increased slightly to 34% for the
three months ended March 31, 1999 compared to 32% for the three months ended
March 31, 1998, resulting primarily from increased utilization of employees and
a reduction in facility costs as a percentage of net revenue, partially offset
by a decline in the industrial engineering operations of ESI, as a percentage
of net revenue. Costs of revenue for the three months ended March 31, 1999 were
$5.9 million compared to $4.1 million for the three months ended March 31,
1998, an increase of $1.8 million, or 45%. Costs of revenue increases resulted
primarily from growth in our employee base from 271 as of March 31, 1998 to 372
as of March 31, 1999, an increase of 101, or 37%. Excluding the acquisition of
John M. Tettemer & Associates in 1998, the number of employees increased by 83,
or 31%.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the three months ended March 31, 1999 were $1.9
million as compared to $1.5 million for the three months ended March 31, 1998,
an increase of $426,000, or 29%. As a percentage of net revenue, selling,
general and administrative expenses decreased to 21% for the three months ended
March 31, 1999 from 25% for the three months ended March 31, 1998. The
percentage decrease resulted primarily from holding the growth in our corporate
labor costs and legal and accounting costs below our internal revenue
increases.

Income Taxes. The provision for income taxes for the three months ended March
31, 1999 was $389,000 compared to a tax provision of $83,000 for the three
months ended March 31, 1998. This increase in tax expense was due primarily to
higher pre-tax income for the three months ended March 31, 1999. Our effective
income tax rate was approximately 42% for the three months ended March 31, 1999
compared to an effective tax rate of 45% for the three months ended March 31,
1998. Our effective income tax rate of 45% for the three months ended March 31,
1998 was primarily due to the anticipated conversion of Keith Engineering from
an S corporation to a C corporation in August 1998.

Years Ended December 31, 1998 and December 31, 1997

Revenue. Net revenue for 1998 was $29.2 million compared to $18.6 million for
1997, an increase of $10.6 million, or 57%. Net revenue increased by $3.9
million and $700,000 as a result of the acquisitions of ESI in December 1997
and John M. Tettemer & Associates in August 1998, respectively. The remaining
net revenue increase of $7.0 million resulted primarily from the overall
strengthening of the California and Nevada economies. These net revenue
increases were partially offset by a $1.0 million decline in our wireless
telecommunications business. Excluding the revenue from the acquisitions of ESI
and John M. Tettemer & Associates, our 1998 net revenue grew $6.0 million, or
32%, compared to 1997. Subcontractor costs, as a percentage of net revenue,
declined to 17% for 1998 compared to 21% for 1997, resulting largely from a
decrease of $465,000 relating to our primary wireless telecommunications
contract which came to substantial completion in 1998.


                                       28
<PAGE>

Gross Profit. Gross profit for 1998 was $9.9 million compared to $6.7 million
for 1997, an increase of $3.2 million, or 47%. Gross profit growth is
attributable to both our internal revenue increases as well as the acquisitions
of ESI and John M. Tettemer & Associates. As a percentage of net revenue, gross
profit decreased slightly to 34% for 1998 compared to 36% for 1997. The decline
in the gross profit percentage is attributable primarily to lower profit
margins in the industrial engineering operations of ESI, which was acquired in
December 1997. Excluding the impact of the ESI acquisition, the gross profit
percentage was 36% for 1998 and 1997. Costs of revenue for 1998 was $19.3
million compared to $11.9 million in 1997, an increase of $7.4 million, or 63%.
Costs of revenue increases resulted primarily from growth in our employee base
from 260 in 1997 to 356 in 1998, an increase of 96, or 37%. Excluding the John
M. Tettemer & Associates acquisition in 1998, the number of employees increased
by 78, or 30%.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses for 1998 were $5.9 million compared to $4.5 million for
1997, an increase of $1.4 million, or 31%. As a percentage of net revenue,
selling, general and administrative expenses decreased to 20% for 1998 from 24%
for 1997. The percentage decrease resulted primarily from the collection of
approximately $390,000 of accounts receivable written off in prior years and
holding the growth in our corporate labor costs below our internal revenue
increases.

Interest Expense. Interest expense for 1998 was $967,000 compared to $852,000
for 1997, an increase of $115,000, or 14%. As a percentage of net revenue,
interest expense was 3% for 1998 compared to 5% for 1997. The percentage
decrease resulted primarily from our increased revenue base and the refinancing
of our line of credit at a lower interest rate in February 1998.

Income Taxes. The provision for income taxes for 1998 was $1.4 million compared
to a tax benefit of $1.4 million in 1997. This increase in tax expense was due
primarily to higher pre-tax income in 1998, the conversion of Keith Engineering
from an S corporation in August 1998 and recording a significant reduction in
our federal valuation allowance in 1997, attributable to our belief that it was
more likely than not that we would be able to realize the benefit of our net
operating loss carryforwards. Our effective income tax rate was approximately
45% for 1998 and would have been approximately 42% had Keith Engineering been a
C corporation at the beginning of 1998.

Years Ended December 31, 1997 and December 31, 1996

Revenue. Net revenue for 1997 was $18.6 million compared to $13.0 million for
1996, an increase of $5.6 million, or 43%. Net revenue increased by $1.6
million as a result of an award of a contract with a wireless
telecommunications client at the end of 1996. The remaining net revenue
increase of $4.0 million resulted primarily from the overall strengthening of
the California and Nevada economies. Subcontractor costs, as a percentage of
net revenue, grew to 21% for 1997 compared to 11% for 1996, resulting primarily
from an increase of $2.8 million relating to the wireless telecommunications
contract awarded at the end of 1996.

                                       29
<PAGE>

Gross Profit. Gross profit for 1997 was $6.7 million compared to $3.7 million
for 1996, an increase of $3.0 million, or 80%. As a percentage of net revenue,
gross profit increased to 36% in 1997 compared to 29% in 1996 reflecting our
ability to expand our revenue through increased utilization of employees and a
reduction in facility and professional insurance costs as a percentage of net
revenue. In addition, the gross profit percentage increased due to improvements
in the overall economy in 1997 resulting in favorable pricing adjustments.
Costs of revenue was $11.9 million for 1997 compared to $9.2 million for 1996,
an increase of $2.7 million, or 29%. Costs of revenue increases resulted
primarily from growth in our employee base from 181 in 1996 to 260 in 1997, an
increase of 79, or 44%. Excluding the acquisition of ESI in 1997, the number of
employees increased by 45, or 25%.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses were $4.5 million for 1997 compared to $5.0 million for
1996, a decrease of $475,000, or 10%. Selling, general and administrative
expenses as a percentage of net revenue decreased to 24% for 1997 from 38% for
1996. The percentage decrease was primarily related to an approximate $822,000
reduction in the provision for doubtful accounts in 1997 compared to 1996.
Concurrently with the prolonged southern California economic recession, in
1996, we reached the conclusion that a significant receivable was uncollectible
and increased our provision for doubtful accounts by $710,000. The increase in
selling, general and administrative expenses, as a percentage of revenue was
impacted by holding the growth in our corporate labor and legal and accounting
costs below our internal revenue increases.

Income Taxes. The income tax benefit for 1997 was $1.4 million compared to a
tax provision of $3,000 in 1996, while our net income before provision for
income taxes and extraordinary gain in 1997 was $1.3 million compared to a net
loss before provision for income taxes and extraordinary gain in 1996 of $1.9
million. The increase in net income before tax and extraordinary gain did not
result in an income tax expense in 1997 primarily due to recording a
significant reduction in our federal valuation allowance, which was
attributable to our belief that it was more likely than not that we would be
able to realize the benefit of our net operating loss carryforwards. The tax
provision for 1996 was not a tax benefit due to a net loss before income taxes
and extraordinary gain generated by Keith Engineering, an S corporation.

Extraordinary Gain. Our 1996 results of operations were impacted by a one time
gain on the forgiveness of a lease liability of $2.7 million. In August 1996,
we entered into an agreement, providing that all amounts owed and accrued under
a lease through December 31, 1995 were forgiven.

Quarterly Results

The following table sets forth unaudited historical and supplemental pro forma
selected quarterly consolidated financial information. Pro forma amounts
reflect adjustments for provisions for federal and state income taxes as if we
had been taxed as a C corporation, at an assumed effective income tax rate of
approximately 42%. On August 1, 1998, Keith Engineering was converted from an S

Our quarterly revenue and operating results fluctuate primarily as a result of:

  .   client engagements commenced and completed during a quarter

  .   seasonality

  .   the number of business days in a quarter

  .   the number of work days lost as a result of adverse weather conditions
      or delays caused by third parties

  .   employee hiring, billing and utilization rates

  .   the consummation of acquisitions

  .   the length of the sales cycle on new business

  .   the ability of clients to terminate engagements without penalty

  .   our ability to efficiently shift our employees from project to project

  .   the size and scope of assignments

  .   general economic conditions

The treatment of $172,000 as compensation expense, resulting from an option
granted in April 1997, and the collection of an account receivable in the
amount of $390,000, previously written off, affected selling, general and
administrative expense in the quarters ended June 30, 1997 and 1998,
respectively.

Liquidity and Capital Resources

We have financed our working capital needs and capital expenditure requirements
through a combination of internally generated funds, bank and related party
borrowings, leases and the sale of our common stock.

Working capital for 1998 was $5.2 million compared to $2.0 million in 1997, an
increase of $3.2 million, or 157%, resulting primarily from growth in accounts
receivable and costs and estimated earnings in excess of billings, due to
higher revenue levels. Cash generated from operating activities increased
$310,000, or 82%, to $686,000 in 1998 compared to $376,000 in 1997, reflecting
our increase in income from operations. The growth in cash generated from
operating activities was used primarily to fund capital expenditures of
$835,000 in 1998 compared to $276,000 in 1997 and to partially finance the
acquisition of John M. Tettemer & Associates. Capital expenditures consisted
primarily of computer equipment, upgrades to our information systems, and
equipment and vehicles used in our survey services.

We maintain a line of credit agreement with a bank, which as of March 31, 1999,
allowed us to borrow up to $5.5 million, not to exceed 80% of our eligible
accounts receivable, as defined in the agreement. On March 5, 1999, the bank
amended the agreement to, among other things, amend some of the financial
related covenants effective December 31, 1998, adjust the interest rate to the
bank's prime rate plus a variable margin tied to financial covenants and extend
the maturity on the line to March 1, 2000. The interest rate on the credit
agreement was 10.5% on March 31, 1999. Cash of $1.8 million drawn on our line
of credit was used primarily for working capital purposes, to repay debt
assumed in acquisitions

                                       32
<PAGE>

and to repay existing debt. At December 31, 1998, we owed $4.5 million on this
line of credit. We expect to repay approximately $2.1 million of the line of
credit with a portion of the net proceeds from this offering. We must meet or
exceed various financial covenants to the bank under the line of credit.

Net cash received from related party borrowings decreased to $156,000 in 1998
from $919,000 in 1997. In addition, in 1997, we received $598,000 from a
related party in exchange for shares of TKCI common stock. The reduction in
cash received from related parties resulted primarily from our increase in cash
generated from operating activities and availability under our line of credit.

On April 9, 1999, TKCI entered into an Asset Purchase Agreement with Thompson-
Hysell and its shareholders. Thompson-Hysell provides real estate services
similar to TKCI in central and northern California and Utah. Under the Asset
Purchase Agreement, TKCI will acquire substantially all of the assets of
Thompson-Hysell, including the right to use its name, and assume substantially
all of its liabilities. TKCI will pay a purchase price of: (a) cash in the
amount of $3,333,333; (b) a promissory note in the amount of $1,333,333 payable
in 2001; and (c) shares of common stock with a value equal to $1,333,334 which
may be issuable in 2000 if earnings goals are met. The purchase price may be
adjusted upward or downward depending upon (a) net assets acquired exceeding
liabilities assumed by $1,000,000; (b) earnings for the years ended December
31, 1999 and 2000; and (c) an adjustment for income tax effects. We expect to
close this acquisition concurrently with this offering. We expect the
operations acquired to increase our revenues, and if the Thompson-Hysell
operations perform as they have historically, to increase our gross margins.

We believe existing cash balances, internally generated funds, and availability
under credit facilities together with the proceeds of this offering will be
sufficient to fund our anticipated internal operating needs for the next twelve
months.

Inflation

Although our operations can be influenced by general economic trends, we do not
believe that inflation had a significant impact on our results of operations
for the periods presented. Due to the short-term nature of most of our
contracts, if costs of revenue increase, we attempt to pass these increases to
our clients.

Year 2000

We are currently in the final phase of identifying and evaluating the potential
impacts of the Year 2000 on information systems and embedded systems. A Year
2000 Mitigation Committee comprised of senior management and functional
managers is evaluating the following issues:

  .   State of readiness
  .   Costs to address Year 2000 issues
  .   Risk assessment
  .   Contingency plan

                                       33
<PAGE>

The following is a description of the process we have established and which we
intend to follow to minimize our Year 2000 risk exposure:

State of readiness. Our information technology and non-information technology
systems can be divided into support/administrative and operational/production
systems. The significant systems used to perform our support and administrative
functions as well as our engineering work and the operating systems upon which
these systems function are detailed in the table below. We have surveyed the
system suppliers and have received from each such supplier either written
assurance or vendor documentation in the form of information published on a
website stating that these systems are Year 2000 compliant, Year 2000 compliant
with minor issues or that a Year 2000 compliance update will be available by
the end of the third quarter of 1999, as indicated below.

We intend to perform internal tests on all mission critical systems and on our
operational production systems to validate Year 2000 compliance by the end of
the third quarter of 1999. We are currently in the process of asking the
vendors of embedded systems to provide us with written assurance of Year 2000
compliance.

                                       35

Cost to address Year 2000 issues. The only costs we have incurred in connection
with addressing Year 2000 issues are administrative expenses resulting from the
efforts of our Mitigation Committee and time spent in attempting to identify
and resolve Year 2000 issues in contacting our vendors and subconsultants to
ensure compliance. These costs are included in selling, general and
administrative expense in the consolidated statements of income. All costs
related to Year 2000 issues are paid from cash flows from operations.

We anticipate a cost of approximately $25,000 to upgrade our telephone voice
message system to ensure Year 2000 compliance. This expenditure will be
recorded as selling, general and administrative expense as incurred. Our
Mitigation Committee has determined that the primary computer systems that we
use are Year 2000 compliant and therefore we do not anticipate any additional
costs related to the Year 2000 date change that will be material to our
business, financial condition or results of operations.

Risk assessment. Based on the findings of our Mitigation Committee, we believe
that the impact of Year 2000 issues on our internal operations will be minimal.
In order to minimize any adverse effect caused by the Year 2000 date change,
our operational personnel transfer their work to back-up tapes on a daily basis
and store these tapes in an offsite location. We have not deferred any
information technology projects due to Year 2000 issues.

We have had difficulty estimating the impact of Year 2000 non-compliance by
outside parties with whom we transact business. We are currently in the process
of surveying our vendors and subconsultants to ascertain their Year 2000
readiness. Because we have not yet completed this survey, we are not in a
position at this time accurately to ascertain the degree of compliance by
vendors and subconsultants with whom we conduct business. However, we have
already received assurances from approximately 15% of these third parties as to
their Year 2000 compliance. Although not all of the vendors and subconsultants
from whom we have received responses are Year 2000 compliant at this time, we
have received assurances that these third parties will be prepared for the Year
2000 date change by the end of 1999.

We have also engaged in discussions with other significant third parties, such
as our bank and payroll service, and have received written assurances regarding
Year 2000 compliance from such service providers. Although our client base is
diverse, with no one client making up more than 10% of our gross revenue, we
have had discussions with our major clients regarding their readiness for the
Year 2000 date change and, for those who have not already given us written
assurance, we expect to receive it by the end of third quarter of 1999.

Contingency plan. Because we have not completed our testing and assessment
procedures, we have not developed any plans for likely scenarios involving Year
2000 failures. By the end of third quarter of 1999, we intend to perform
internal tests on all mission critical systems and on our operational
production systems to validate Year 2000 compliance. If, when testing and
assessment is complete, it appears reasonably likely that such a Year 2000
failure may occur, management intends to develop appropriate plans to deal with
such contingencies. If we are unsuccessful in developing or implementing a plan
to correct possible Year 2000 failures, or if we fail properly to anticipate a
Year 2000 failure either in our information technology (software) or non-
information technology (microcontrollers in

                                       36
<PAGE>

equipment), we may experience disruptions in operations. Our projection of the
most serious disruptions which could occur include:

  .   the loss of approximately two months' net revenue, an amount of
      approximately $6,000,000, if our accounting systems fail and we are
      unable to utilize backup information. We would, however, expect
      eventually to be able to recover a significant portion of this revenue
      by recreating time and cost entries from hard copies of such data.

  .   the loss of engineering and project data if we are unable to utilize
      backup information, resulting in the need to re-input printed data.
      This effort could increase operating costs and reduce margins in the
      first two quarters of 2000 and might cause the loss of some projects
      if we are unable to fulfill our time commitments.

  .   the loss of the services of subcontractors who are experiencing
      disruptions due to Year 2000 risks, resulting in the loss of contracts
      because of failure to meet deadlines.

  .   the loss of net revenue if any of the accounting systems of our
      clients experience a Year 2000 failure.

           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to interest rate changes primarily as a result of our line of
credit, long-term debt, capital leases and notes payable to related parties,
which are used to maintain liquidity and to fund capital expenditures and our
expansion. Our interest rate risk management objectives are to limit the impact
of interest rate changes on earnings and cash flows and to lower our overall
borrowing costs. To achieve our objectives, we have borrowed at fixed rates and
may enter into derivative financial instruments to mitigate our interest rate
risk on variable rate debt. We do not enter into derivative or interest rate
transactions for speculative purposes.

The table below presents the principal amounts, weighted average interest
rates, fair values and other items required by year of expected maturity to
evaluate the expected cash flows and sensitivity to interest rate changes.
Dollars are expressed in thousands.

(1) The fair value of fixed rate debt and variable rate debt was determined
    based on current rates offered for debt instruments with similar risks and
    maturities.
(2) Fixed rate debt excludes notes payable with an aggregate principal amount
    of $576,000 as there is no established market for these notes.

As the table incorporates only those exposures that existed as of December 31,
1998, it does not consider those exposures or positions which could arise after
that date. Moreover, because firm commitments are not presented in the table
above, the information presented in the table has limited predictive value. As
a result, our ultimate realized gain or loss with respect to interest rate
fluctuations will depend on those exposures or positions that arise during the
period and interest rates.

General

We began operating in 1983 as Keith Engineering, which was incorporated on
March 1, 1983. We formed TKCI in November 1986, under the name The Keith
Companies-Inland Empire, Inc., and merged the two companies in November 1998
with TKCI as the survivor. We provide engineering, consulting and technical
services to clients operating in a variety of environments.

Industries Served

The industries we serve are real estate development, public works and wireless
telecommunications and industrial engineering.

 Real Estate Development, Public Works and Wireless Telecommunications

Real Estate Development

Residential, commercial and golf and other recreational developers use
technical consultants to provide planning and environmental services to create
land use plans, write the supporting planning and environmental documents and
process entitlements and permits through governmental authorities. Technical
consultants also assist clients in gaining approvals and permits from federal,
state and local agencies. After projects are approved by governmental agencies,
developers need surveying, mapping and civil engineering services to survey
development sites, create accurate boundary/base maps and provide engineering
designs for mass grading, streets, sewer pipelines and facilities, water
pipelines and facilities, utilities and drainage facilities. Upon completion of
the design phase, survey crews provide construction staking services to
identify the precise locations of streets, utilities, pipelines and other
facilities. In culturally sensitive projects or areas, developers may also
require environmental and archaeological services for the planning and
environmental approvals and construction and post-construction phase monitoring
services.

The U.S. real estate industry is commonly segmented into four geographic
regions: northeast, south, mid-west and west. We operate in the west region,
primarily in California and in Nevada and Utah. During the last economic upturn
in the real estate industry in southern California, which we believe lasted
eight years from 1983-1990, our gross revenue and number of employees grew.
During the following downturn in southern California, through 1996, we
experienced a reduction in revenue and employees. We believe that the southern
California real estate market is in the third year of an economic upturn. In
1998, approximately 50% of our net revenue was derived from services rendered
in connection with commercial and residential real estate developments in
southern California.

Residential. The residential development industry consists of large scale
communities, seniors/retirement communities, single family homes and multi-
family homes, like condominiums and apartments. The issuance of building
permits is an important economic indicator in forecasting housing starts. The
following table from Regional Financial

According to a 1997 population report released by the U.S. Bureau of the
Census, California, Nevada and Utah are projected to be among the top seven
fastest growing states in population growth during the thirty year period from
1995 to 2025. In March 1999, the U.S. Bureau of the Census also reported that
of the nation's 3,142 counties, the four southern California counties of Los
Angeles, Orange, San Diego and Riverside and Clark county, Nevada were among
the top seven in population gains between 1997 and 1998. A comparison of a
March 1999 report prepared by Dismal Sciences, Inc. showing population growth
for the nation to a December 1998 report prepared by Regional Financial
Associates, Inc. showing population growth for the West indicates that since
1991, the West has outpaced the nation in population growth. In its report,
Regional Financial Associates, Inc. forecasted that the population in the West
would continue to outpace the nation over the next four years.

The following three tables from Regional Financial Associates, Inc. and Dismal
Sciences, Inc. show historical demographic data for 1996-1997 and forecasted
demographic data for 1998-2000 for population, employment and personal income.

Commercial. The commercial development industry includes the construction of
retail, office and industrial facilities. Important economic indicators in
forecasting commercial development include, among others, growth in employment
and personal income. According to research conducted in 1998 by Regional
Financial Associates, Inc., employment and personal income in the West are
projected to grow by an annual average of approximately 2.0% and 6.1%,
respectively, from 1999 to 2002. Colliers International reported in a 1999
market study that retail development in Las Vegas continues to grow, with
approximately 4 million square feet of new retail in the planning phase and 1.4
million square feet under construction. This constitutes an approximate 26%
increase over the existing 21 million square feet. Colliers also forecasts that
with residential growth continuing to fuel retail growth in the Nevada
marketplace, the construction of in-fill/neighborhood and community centers
lead retail development growth with a 25% planned growth rate.

According to 1998 and 1999 Grubb & Ellis Real Estate Forecasts, during 1997,
the United States' economy generated 730,000 new office jobs, national office
vacancy rates moved toward or even dropped below what is considered the
market's equilibrium and lease rates rose 25% or more in some markets; and in
1998, construction rose from 49 million square feet underway at year end 1997
to 90 million square feet at year end 1998. A report prepared by the U.S.
Census Bureau indicated that, for 1998, office building construction totaled
$38.2 billion, a 16% increase over 1997. The McGraw-Hill Construction
Information Group of the McGraw-Hill Companies forecasts office building
construction to increase by 9% in 1999.

Golf and Other Recreational Facilities. The most significant proportion of our
revenue from golf and other recreational projects is derived from golf related
projects. According to the 1998 edition of Golf Participation in the United
States and Trends in the Golf Industry, the United States currently has 26.5
million golfers over age 12, a 33% increase from 1986. Likewise, the National
Golf Foundation published a report in March 1999 stating that there were 448
new course openings in 1998 as compared with 10 years ago when the industry was
averaging less than 175 course openings per year. In addition, the National
Golf Foundation states that the number of courses in planning and construction
increased from 1,652 on January 1, 1998 to approximately 1,777 on January 1,
1999, a 7.6% increase. Lastly, as of December 31, 1998, according to the
National Golf Foundation, California is ranked among the top three states for
total number of existing courses, new course openings, courses under
construction and courses related to real estate development.

Public Works

Transportation, water resources, and other public works projects may provide
ongoing, reliable sources of revenue for engineering firms and consultants when
private development activities decline during unfavorable economic periods.
These public projects are often long-term and ongoing, and have historically
provided more determinable and consistent revenue streams.

Transportation. Highway and interchange projects require engineering designs
for roadways, interchanges, the placement or relocation of sewer lines, water
pipelines and utility lines and rainfall run-off management. In a recent
publication, the American Society of Civil Engineers reported that as much as
$1.3 trillion of capital investment is currently necessary to repair and renew
our infrastructure to meet our growing needs. In 1998, the U.S. Congress
authorized funding of $175 billion under the Transportation Equity Act for the
21st Century for highway projects over the next six years, a 44% increase over
the previous funding program according to the McGraw-Hill Companies. According
to the McGraw-Hill Construction Information Group, non-building construction in
the western states will experience the largest growth, which is expected to be
up 14% in 1999 over 1998.

According to the California Department of Transportation, Governor Gray Davis
has proposed more than $7.9 billion to fund Caltrans during the 1999-2000
fiscal year, which is approximately $1.6 billion more than the 1998-1999 fiscal
year. The largest portion of this budget is $3.9 billion for ongoing and new
highway construction projects, according to the California Department of
Transportation.

Water Resources. Public water resource projects include the installation,
rehabilitation or replacement of facilities or infrastructure for:

  .   protection of water sources
  .   dams or reservoirs
  .   water treatment
  .   water pipelines
  .   collection of wastewater
  .   sewer lines
  .   treatment of wastewater

In 1998, the American Society of Civil Engineers published the 1998 Report Card
for America's Infrastructure. This report states that the total infrastructure
investment needs for drinking water remain large--$138.4 billion according to
the Environmental Protection Agency--more than $76.8 billion of which is
currently needed to protect public health. This organization also reported that
America needs to invest roughly $140 billion over the next 20 years in its
wastewater treatment systems and that an additional 2,000 plants may be
necessary by the year 2016 to meet expanded treatment goals.

Wireless Telecommunications

With the emergence and growth of personal communication services and the
conversion from analog technology to digital technology, the demand for the
development and

                                       42
<PAGE>

construction of new wireless transmission base stations, switching centers and
microwave link networks has increased. For the development of most wireless
telecommunications networks, wireless service providers hire outside experts in
site acquisition/lease arrangement, land planning, permitting, civil
engineering, selecting and purchasing equipment and/or construction management.
The development costs for a typical base station in southern California are
approximately $350,000 to $500,000, of which engineering, consulting and
technical services may account for approximately $50,000.

Wireless subscriber growth is the main driver in demand for new tower sites,
according to a 1998 business model by Morgan Stanley Dean Witter Equity
Research. In 1998, the Cellular Telecommunications Industry Association
predicted that the number of United States wireless customers would grow from
an estimated 124 million in 1998 to an estimated 209 million in 2003 and
expected the compounded average growth rate from 1998 to 2003 to be 11%. The
Personal Communications Industry Association estimated that 12,000 to 20,000
new towers are needed by 2003 to accommodate the growth of wireless services.
In 1998, the Cellular Telecommunications Industry Association stated that the
total number of communication sites would grow from 38,650 at the end of 1997
to approximately 100,000 by the year 2000.

Modern machines, assembly lines, factories and refineries require industrial
engineering services to enable utilization of new processes and to improve
efficiency and reliability. Comprehensive industrial engineering services
include: (a) the design or redesign of electrical and heating, ventilation and
air conditioning systems; (b) mechanical equipment design; (c) equipment
selection and purchasing; (d) the design of integrated computer and monitoring
device systems to control manufacturing and processing equipment; (e) chemical
process engineering; (f) energy usage consulting; (g) fire protection
engineering; (h) material handling and process flow planning; (i) automation
and robotics design; (j) construction management and installation supervision;
(k) project management; and (l) computer programming.

Industrial engineering projects which utilize engineering, consulting and
technical services include:

  .   High Tech Facilities: biotechnology, pharmaceutical, and laboratory
      facilities, computer centers, control rooms, research and development
      facilities

  .   Consumer Product Facilities: automotive assembly, household products
      and packaging facilities

  .   Food and Beverage Facilities: bottling/packaging facilities, material
      handling facilities, process controls, food and beverage manufacturing
      facilities

  .   Educational Facilities: schools and universities

  .   Public Facilities/Utilities/Energy/Power: power plants, natural gas,
      electric

We believe there is a continued trend in the manufacturing and assembly
industry toward automation and increased efficiency. As these industries grow,
so does their need for design and engineering services to automate and increase
efficiency of new and existing facilities.

                                       43

According to a 1998 Standard & Poor's survey of annual revenue growth rates in
the United States, the biotechnology industry is expected to grow by 20% and
25% in each of 1999 and 2000, the packaged food and beverage industry is
expected to grow by 10% in 1999, and the non-alcoholic beverage sector is
expected to grow between 8% and 12% in 1999. We expect these industries to
increase their use of automation to make their facilities more efficient.

The TKCI Advantage

The engineering, consulting and technical services industries are highly
fragmented, ranging from a large number of relatively small local firms to
large, multi-national firms. We estimate that there are over 500 firms
providing the engineering, consulting and technical services to the industries
we serve in our principal operating areas. We believe that we have successfully
penetrated the regional residential real estate industry to capture a
significant share of the market and establish ourselves as a leader in the
market. In California, Nevada and Utah, approximately 908,172 residential
building permits for individual residential units, consisting of permits for
single-family and multi-family dwellings, have been projected for issuance in
1999 through 2002. In these locations, we expect to provide ongoing and
expanded services on projects which we believe will be comprised of over
100,000 individual residential units. These projects range in duration from
less than one year to more than five years. We believe that we can further
enhance our leading position in the western United States in the industries we
serve for the following reasons:

 Reputation

Our reputation for providing high quality services has been a source of
numerous project assignments. We believe our reputation is strengthened due to
the personal relationships developed between our staff and representatives of
clients and agencies. We have been awarded many projects either due to our
expertise in working with an agency or project type or because a particular
client desires to work with, and can count on, specific project managers. In
addition, we have received numerous awards for technical excellence including
the Project of the Year Award of Excellence in the award category of
Engineering Land Development for the "Dana Point Townhomes" project from the
California Council of Civil Engineers and Land Surveyors; a Certificate of
Recognition for the design of the "Grand Avenue and Chino Hills Parkway"
awarded by the County of San Bernardino, California Board of Supervisors; and a
Letter of Appreciation from the Department of General Services of the State of
California for contributing to the "Telecommunications Leasing Program" and for
our assistance in formulating telecommunications real estate objectives and
strategies.

 Industry and Professional Experience

We recognize that our employees are our most valuable resource for providing
ongoing quality service and for obtaining new work. Of our staff of over 450,
we have over 100 individuals with professional licenses. During employee
selection and as part of our acquisition criteria we require that the people
added to our team have significant experience in the industries they serve. We
supplement this industry experience by providing in-house continuing education
seminars, design forums and training programs.

                                       44

 Full Service Approach

We provide civil engineering, surveying and mapping, planning, environmental,
archaeological, construction management, site acquisition, water resource
engineering, instrumentation and control systems engineering, fire protection
engineering, electrical engineering, mechanical engineering and chemical
process engineering services. Since many engineering, consulting and technical
services firms specialize in only one or a few services, a project owner may
often be required to engage several engineering and/or consulting firms during
the various phases of a project. The phases range from identifying and
evaluating whether to acquire a parcel of land to designing, engineering and
managing the construction of the finished project. We believe that clients
realize significant cost and time savings and maintain consistent quality by
utilizing a single firm for all services.

 Cross-Marketing

Due to our reputation and industry and technical expertise, we have frequently
increased the number and scope of services provided to a client from an initial
engagement, like land planning, to include other services, like mapping and
surveying. When we expand into new geographic regions, we have successfully
cross-sold and intend to continue to cross-sell services offered by one office
to clients in another office.

Because our professionals provide many of the preliminary services on planning,
civil engineering and surveying and mapping projects, we are frequently asked
to bid on additional services on a project as it progresses. In performing the
preliminary services in the initial phases of a project, we obtain background
information and data relating to the project that may be inefficient and costly
for another firm to compile. Consequently, we are often more knowledgeable
about a project, and, as a result, we are often engaged to perform the
additional engineering and consulting services that the client requires as the
project progresses.

 Effective Organizational Structure

We believe that our organizational structure allows us to compete effectively
with small and mid-size local firms and with large regional and national firms.
Our organizational structure combines the efficiencies associated with
centralization and the flexibility of decentralization. Our administrative
functions are centralized in our corporate headquarters in Costa Mesa,
California allowing us to eliminate duplicative functions and personnel at our
divisional offices. We believe this centralization allows the management at our
divisional offices the freedom to focus on identifying new business
opportunities and overseeing the technical services provided in that office,
and allows the flexibility for those managers to maintain focus on being
responsive to client needs. The centralization of administrative functions also
allows us effectively and efficiently to integrate acquired companies.

Business Strategy

Our objective is to strengthen our position as a leading provider of
engineering, consulting and technical services while growing our geographic
presence and expanding the services we offer.

                                       45
<PAGE>

To achieve this objective, we have developed a strategy with the following key
elements:

   .   Maintain High Quality of Service. To maintain high quality service,
       we focus on being responsive to customers and working diligently and
       responsibly to maintain schedules and budgets. As a result of our
       focus on quality and timeliness of service, we believe that we have
       established an excellent reputation in the markets we serve. We
       intend to continue providing high quality service as we expand our
       geographic presence and service offerings.

   .   Continue to Recruit and Retain Highly Qualified Personnel. We believe
       that recruiting and retaining skilled professionals is crucial to our
       success and our growth. As a result, we intend to continue to recruit
       experienced and talented individuals who can provide quality services
       and innovative solutions for our clients' projects. We believe that
       our employee benefits package provides incentives that enable us to
       continue to attract the most qualified candidates.

   .   Expand Geographically. To diminish the impact of regional economic
       cycles, we intend to continue to expand our geographic presence by
       making acquisitions, opening additional divisional offices and
       marketing our services to clients with national and international
       needs. Our geographic growth will provide us with broader access to
       employee pools, work sharing between regions and new business
       opportunities. We believe the acquisition of Thompson-Hysell will
       enable us to more effectively sell additional services in both
       central and northern California and Utah. We intend to continue to
       increase our service offerings outside of California, Nevada and
       Utah.

   .   Expand Scope of Services. We intend to build upon our reputation as a
       quality provider of real estate related engineering, consulting and
       technical services as we diversify our services to meet new demands
       of clients and the demands of new markets. As part of our effort to
       continue diversifying our scope of services, we intend to pursue
       strategic partnering relationships and acquisitions.

   .   Continue to Effectively Integrate Acquired Operations. We intend to
       continue to pursue acquisitions that expand our range of services
       and/or our geographic presence and that result in an increase in our
       operating efficiencies. We believe that strategic acquisitions will
       enable us to more efficiently and quickly serve the diverse technical
       and geographic needs of, and secure additional business from, our
       national and international clients.

We have implemented our strategy by (a) providing services to the wireless
telecommunications industry; (b) obtaining a subcontract to assist Marconi
Integrated Systems, Inc. in a global mapping project for the National Imagery
and Mapping Agency; (c) acquiring ESI and John M. Tettemer & Associates; and
(d) engaging in the acquisition of Thompson-Hysell. This diversification of our
services has broadened our geographic presence, expanded the number of
industries we serve and added our capability to provide water resources,
environmental, mechanical, electrical, chemical process, and fire protection
and other industrial engineering services.

                                       46

Services Provided

We provide a broad range of services, including civil engineering, surveying
and mapping, planning, environmental, archaeological, construction management,
site acquisition, water resources engineering and other industrial engineering
services, including instrumentation and control systems engineering, fire
protection engineering, electrical engineering, mechanical engineering and
chemical process engineering.

 Civil Engineering Services

General civil engineering is often referred to as "design from the ground down"
because it is part of all construction design work on the ground and below.
Civil engineering services include:

  .   project feasibility and due diligence analysis
  .   development cost projections
  .   access and circulation analysis
  .   infrastructure design and analysis
  .   pro forma cost studies
  .   project management
  .   construction documents
  .   tentative mapping
  .   flood plain studies
  .   sewer, water and drainage design
  .   street and highway design
  .   site/subdivision design
  .   grading design

As an example of how our civil engineering services are utilized, our engineers
were the master engineers for the Newport Coast development in southern
California. This development consists of over 9,000 acres that has been planned
for more than 1,800 residential units, two destination resorts, two
championship golf courses within the Pelican Hill Golf Club and over 7,300
acres of dedicated open space. We were responsible for the preparation of a
majority of the preliminary and final civil engineering designs, and provided
the project with land surveying, mapping, water resources and archaeological
services. In addition, as the infrastructure engineer for this project, we
completed the master drainage plan, designed the master water and sewer
facilities and designed many of the primary roadways.

 Surveying and Mapping Services

From establishing boundaries for preliminary engineering through construction
layout and as-built surveys, it is common for our surveying and mapping teams
to be "the first in and the last out" on a construction project. We provide
surveying and mapping services through our teams of skilled professionals that
utilize sophisticated technology, including global positioning systems which
utilize satellite technology to survey and navigate land, geographic
information systems, and field-to-office digital and electronic data capture,
to

                                       47
<PAGE>

produce information that will serve as the foundation for a variety of planning
and engineering design and analysis endeavors. Our surveying and mapping
services also include the identification of features of a parcel of land that
directly affect a project's design. We were among the first engineering and
surveying consultants to utilize global positioning systems with geographic
information systems to conduct precise ground surveys.

We utilized our expertise in the use of ground and global positioning systems
surveys to plot the aftermath of the Mt. Pinatubo eruption in the Philippines
for a long-term lava flow management project. For Cox Communications (formerly
Sprint), we provided site topographic and boundary surveys for approximately
400 proposed cellular telecommunication sites. Using these surveys, we designed
and generated construction documents and developed legal descriptions that were
used in lease contract documents. Government agencies and landowners have also
utilized our surveying and mapping services to develop the basic elements of
their geographic information systems databases.

 Planning Services

Planning services include both physical planning and policy planning. Physical
planning is graphical and includes conception and layout of communities, land
uses and residential and commercial neighborhoods. The resulting plan often
becomes the basis for the preparation of engineering plans. To complement a
physical plan, policy planning entails the preparation of supporting text and
documents that establish procedures, requirements and guidelines for visual
appearance under which the physical plan may be implemented.

Our planning services are designed to assist clients in maximizing the
potential uses of real estate and other limited resources. We provide plans
that take into account government regulations, effective and creative use of
land assets, and the expectations and needs of the community.

An example of our planning services was our involvement in the design of a
major flood control dam on a 10,000 acre project in Los Angeles County that
controlled yearly flooding of Palmdale, California, a downstream municipality,
significantly reducing the cost of infrastructure for flood control facilities.
Our solution allowed plans for concrete channelization of the waterway to be
abandoned. This resolved the concerns of the local water agencies and
environmentalists which were concerned with groundwater recharge and
replenishment. It also provided the inducement for the city to annex and
entitle the project. Other projects for which we have provided planning
services include Hanalei Garden Farm Estates in Hawaii, Jian Zhuan Lake Resort
in China, a Jack Nicklaus Golf Course at Lake Las Vegas and Hurricane Iniki
Emergency Permitting in Hawaii.

 Environmental Services

Our environmental services include biology, permit processing, document
preparation and mitigation monitoring. We assist clients with the complex
federal, state and local permitting process enabling them successfully to
implement private and public projects.

                                       48
<PAGE>

As an example of our environmental services, we prepared design plans and
analyses for the creation of a constructed wetlands project in southern
California. This facility uses natural processes for extensive nitrate removal
from water that flows from upstream dairy farms. The water is stored for
groundwater recharging and used to supplement the drinking water supply.

 Archaeological Services

Many environmental impact analyses require protection of significant
archaeological resources which may exist on a property, like native peoples'
community settings, artifacts and burial sites. We perform studies which range
from site review and records analysis to a discussion of measures to protect
sensitive or valuable archaeological resources. Further, we conduct field
sampling and testing to establish or verify site review and records information
and determine both the quantity and quality of archaeological materials on a
given site.

An example of the use of our archaeological services is when, after performing
civil engineering services on a project for a client, the client asked us to
provide archeological services on a different project in southern California.
For this project, our archaeological staff mobilized, organized and supervised
a team of 25 people in the excavation of a fossil whale bed. In the course of
this excavation, we found rare samples of Baleen whales, which were
subsequently donated for further academic study.

 Construction Management Services

Construction management services are an efficient "bundling" of some of the
other services which we provide. We direct development and construction tasks,
including the preparation of cost projections, entitlement and feasibility
analysis, professional consultant selection and supervision, contractor
bidding, and construction supervision. We provide these services in discrete
components or as a comprehensive package for private development, public works
and wireless telecommunications clients.

An example of our construction management services is a master planned
community in Chino Hills, California, where a developer retained us to manage,
plan, design, permit, stake and subcontract a 620 acre community, consisting of
1,410 residential units and associated park and community facilities.

 Site Acquisition Services

We provide site acquisition services to assist our clients in obtaining the
most appropriate real estate for their particular needs. For example, a
property intended for the development of multi-family housing will have
characteristics which vary greatly from that of a property intended for the
siting of a heavy industrial use. We provided site acquisition services for
over 450 wireless communications sites in Riverside, San Bernardino, Ventura,
Los Angeles and San Diego counties for Cox Communications (formerly Sprint), a
national wireless services provider.

                                       49
<PAGE>

 Water Resources Engineering Services

Our water resources engineers frequently assist clients in financial planning,
feasibility studies, demand forecasting, and hydraulic analysis, the study of
how water flows, to develop system master plans in addition to designing
conventional systems of pipes, channels and dams.

Examples of the water resources engineering services that we have provided
include: (a) the performance of a study in which we evaluated the anticipated
amount of rainfall water in a 23 square-mile watershed in Riverside County,
California; and (b) the development of a concept report and preliminary design
for a 2,000 acre-feet, 50 foot high water quality dam, a major sediment
detention basin facility and the relocation of approximately 1.5 miles of
roadway, all incidental to the construction of the dam and related structures.

 Industrial Engineering Services

In addition to the engineering, consulting and technical services described
above, we also provide the following industrial engineering services:

Instrumentation & Control Systems Integration Engineering Services.  Our
professionals integrate equipment selection, maintenance requirements and spare
parts inventory by designing, selecting and reviewing mechanical, piping and
electrical layouts, and operating maintenance, training, start-up and emergency
procedures during the design of contemporary processes or the automation of
outdated manufacturing processes. These services are essential to creating an
efficient and safe operating facility.

Fire Protection Engineering Services. We provide fire protection engineering
services in connection with both new construction and the
renovation/modification of existing facilities to assist our clients in
defining and providing an acceptable level of fire safety in a cost-effective
manner.

Electrical Engineering Services. These services include design of electrical
power systems for buildings, manufacturing plants, and miscellaneous
facilities, design of lighting systems, and selection of other equipment which
delivers or uses electrical power.

Mechanical Engineering Services. These services are required to design energy
systems, HVAC systems, plumbing systems, water distribution systems and fire
protection systems for facilities and buildings.

Chemical Process Engineering Services.  Our chemical and process engineers
design systems for a variety of manufacturing and industrial facilities and
processes. These services are necessary for the design of chemical processing
operations in industries like food and beverage, pharmaceutical, chemical and
petroleum.

Sales and Marketing

Our Client Services Department is dedicated to business development and
marketing activities. We employ a variety of strategic business development and
marketing techniques

                                       50
<PAGE>

to obtain contracts with new clients and repeat business with existing clients
and to maintain our positive reputation. With our expansion of services in the
past several years, cross-selling our services has become a large component of
our active promotional efforts. Our marketing advantage in selling additional
services is enhanced when we have already provided initial services on the
project. For example, when we have provided planning and civil engineering on a
project, we have an advantage over our competitors in successfully cross-
selling our other services, like mechanical and electrical engineering. Our
Client Services Department identifies and pursues these opportunities. A large
portion of revenue is generated from ongoing work opportunities on long-term,
large scale projects.

In addition, our Client Services Department assists our in-house management and
clients to assure quality performance and client satisfaction. To accomplish
this effort, we provide clients with referrals to project partners and
financing sources, assistance in legislative matters, monitoring of in-house
performance and many other nontechnical support functions.

Our Client Services Department also identifies projects and clients in each of
the markets in which we are active. This is achieved through the use of many
resources such as: geographic information systems maps and aerial maps,
project/contact databases, the Internet, and leads publications, which track
most public works and public agency projects. Our Client Services Department
pursues those companies, agencies, projects and markets that have financial
strength, long term growth potential and reputation.

One of our most effective methods of winning new contracts has been the
Executive Land Search program. We have developed map rooms containing
computerized geographic information systems maps, aerial maps, and city and
county maps. These cover most of the geographic regions in which we are active
and identify a number of available properties which are of interest to our
clients. We meet with existing and prospective clients and refer available
projects to them in the hope of being selected to provide our services if they
successfully acquire the project. For example, upon referring a large
undeveloped parcel of land in southern California to a land development company
that was not an existing client, we were awarded multiple contracts to provide
planning, civil engineering, mapping and surveying services which, by June 4,
1999, had resulted in over $1,500,000 in contract value.

Clients

We serve clients in the real estate development, public works and wireless
telecommunications and industrial engineering industries. Our primary private
clients consist of real estate developers, builders, wireless
telecommunications providers, and major manufacturers. Our public clients
include water and school districts, cities, and other local, state and federal
government agencies.


                                       51

 Kellogg U.S.A. Inc.
 Toyota Motor Company

In 1997, The Irvine Company accounted for 11% of our net revenue. No individual
client accounted for more than 10% of our net revenue in 1998.

Backlog

Our backlog represents (a) an estimate of the remaining future gross revenues
from existing signed contracts and (b) contracts which have been awarded, with
a defined scope of work and contract value and on which we have begun work with
verbal client approval. The backlog estimates do not include projected revenues
from those projects for which we have provided services and anticipate
additional services to be requested.

Because our professionals provide much of the preliminary services planning,
civil engineering and surveying and mapping projects, we are frequently called
upon to expand the scope of our work on a project as it progresses. In
performing the preliminary services in the initial phases of a project, we
obtain background information and data relating to the project that may be
inefficient and costly for another firm to compile. As a result of this
knowledge about the project, we are often chosen to perform the additional
engineering and consulting services that these clients require as the project
progresses.

At March 31, 1999, our backlog was approximately $22 million, of which
approximately $20 million is expected to be completed in 1999. Comparable data
for the amount of backlog for 1998 is unavailable because the upgrade to our
accounting software which enables us to generate our backlog information was
not installed until January 1999. Our engagements are terminable at will, and
no assurance can be given that we will receive any of the revenues associated
with the backlog described above.

                                       52

Competition

We believe that our principal competitors of our size or larger are: Robert
Bein William Frost & Associates, Hunsaker & Associates, Inc., Psomas and Nolte
& Associates, in the real estate development market; Tetra Tech, URS
Corporation, and Black & Veatch Corporation, in the public works market; The
Planning Center, in the wireless telecommunications market; and The Bentley
Companies, Eichleay Engineers and Jacobs Engineering Group, in the industrial
engineering market. In any market there are also several smaller firms with
which we compete.

We believe that the principal factors in the engineering, consulting and
technical services selection criteria include, in order of importance:

  .   quality of service
  .   relative experience
  .   staffing capabilities
  .   reputation
  .   geographic presence
  .   stability
  .   price

Employees

We have 461 employees, of which over 400 are technicians and technical
professionals. Believing that our success depends significantly upon attracting
and retaining talented, innovative and experienced professionals, we are
comprised of highly skilled personnel with significant industry experience and
strong client relationships. We employ licensed civil engineers, mechanical
engineers, electrical engineers, land surveyors, landscape architects,
certified planners, information technology specialists, biologists, doctoral
archaeologists and geodesists involved in studying the shape of the earth.

Our field survey employees in our southern California offices are covered by a
Master Labor Agreement between the International Union of Operating Engineers
and the Southern California Association of Civil Engineers and Land Surveyors.
The agreement applies to civil engineering and land surveying work, including
global positioning system surveys, and covers our employees in Imperial, Inyo,
Kern, Los Angeles, Mono, Orange, Riverside, San Bernardino, San Diego, San Luis
Obispo, Santa Barbara and Ventura counties. Our field survey employees in our
Northern California offices are covered by a Master Agreement between the Bay
Counties Civil and Land Surveyors Association and Operating Engineers Local
Union No. 3. Our other employees are not represented by any labor union and we
have never experienced a work stoppage from union actions. We believe that our
relationship with our employees is good.

Facilities

We occupy offices and facilities in various locations in California, Nevada
and, with the acquisition of Thompson-Hysell in Utah. Our corporate
headquarters are located in Costa

                                       53
<PAGE>

Mesa, California and consist of approximately 49,000 square feet of space. Our
monthly rent for this space consists of a base rent, including common area
maintenance of approximately $71,200, with periodic adjustments. Our lease
extends until July 31, 1999. We are currently negotiating to enter into a new
sublease for approximately 33,000 square feet of our current facility for an
additional four years and a new lease for the remaining approximately 16,000
square feet of our current facility for an additional two years. Under the
proposed leases, our monthly rent will initially increase by approximately
$11,000. We also maintain offices at another location in Costa Mesa and have
additional offices in the California cities of Walnut Creek, Moreno Valley,
Modesto and Palm Desert; one office in Las Vegas, Nevada; and one office in
Taylorsville, Utah. We expect to open an additional office in Salinas,
California during 1999.

Legal Proceedings

From time to time, we have been involved in routine litigation incidental to
the conduct of our business. There are currently no material pending litigation
proceedings to which we are a party and no claims for which the liability to us
would be in excess of our insurance coverage.

Aggregated Option Exercises in 1998 Fiscal Year and Fiscal Year End Option
Values

  There were no exercises of options by any named executive officers in the
fiscal year ended December 31, 1998.

Stock Option Plans

We have adopted an Amended and Restated 1994 Stock Incentive Plan effective as
of March 31, 1999. The plan is administered by the Compensation Committee of
the board of directors, which has discretion and authority, consistent with the
provisions of the plan, to determine which eligible participants will receive
options, the time when options will be granted, the terms of options granted
and the number of shares which will be issuable upon exercise of options.

Our plan provides for the granting of "incentive stock options" within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended,
nonqualified options and rights to purchase shares of common stock. Under the
plan, options and purchase rights covering an aggregate of 1,111,111 shares of
TKCI's common stock may be granted, in each case to officers, directors, key
employees and consultants of TKCI and its subsidiaries, except that incentive
stock options may not be granted to nonemployee directors or nonemployee
consultants. The exercise price of incentive stock options must not be less
than the fair market value of a share of common stock on the date the option is
granted and must

                                       59
<PAGE>

not be less than 110% with respect to optionees who own at least 10% of the
outstanding common stock. Our Compensation Committee has the authority to
determine the time or times at which options granted under the plan become
exercisable, provided that options expire no later than ten years from the date
of grant, or five years with respect to incentive stock options held by
optionees who own at least 10% of the outstanding common stock. Options are
nontransferable, other than by will and the laws of descent and distribution,
and generally may be exercised only by an employee while employed by TKCI. The
plan terminates in July 2004. As of March 31, 1999, options to purchase 485,074
shares of common stock were outstanding under the plan.

Indemnification of Directors and Officers

The articles of incorporation of TKCI as amended, provide that the liability of
our directors for monetary damages shall be eliminated to the fullest extent
permissible under California law. This is intended to eliminate the personal
liability of a director for monetary damages in an action brought by or in the
right of TKCI for breach of a director's duties to TKCI or our shareholders
except for liability: (a) for acts or omissions that involve intentional
misconduct or a knowing and culpable violation of law; (b) for acts or
omissions that a director believes to be contrary to the best interests of TKCI
or our shareholders or that involve the absence of good faith on the part of
the director; (c) for any transaction for which a director derived an improper
personal benefit; (d) for acts or omission that show a reckless disregard for
the director's duty to our shareholders in circumstances in which the director
was aware, or should have been aware, in the ordinary course of performing a
director's duties, of a risk of serious injury to TKCI or our shareholders; (e)
for acts or omissions that constitute an unexcused pattern of inattention that
amounts to an abdication of the director's duty to TKCI or our shareholders;
and (f) for engaging in transactions described in the California Corporations
Code or California caselaw which result in liability, or approving the same
kinds of transactions.

Our articles of incorporation also provide that we are authorized to provide
indemnification to our officers and directors in excess of the indemnification
otherwise permitted by Section 317 of the California Corporations Code. Our
bylaws provide for indemnification of our officers, directors, employees, and
other agents to the extent and under the circumstances permitted by California
law.

We have entered into agreements to indemnify our directors and executive
officers in addition to the indemnification provided for in our articles of
incorporation and bylaws. Among other things, these agreements provide that we
will indemnify, under appropriate circumstances, each of our directors and
executive officers for expenses, including attorneys' fees, judgments, fines
and settlement amounts incurred by that person in any action or proceeding,
including any action by or in the right of TKCI, on account of services
provided as a director or executive officer of us, or as a director or
executive officer of any other company or enterprise to which the person
provides services at our request.

<PAGE>

                              CERTAIN TRANSACTIONS

In November 1998, we entered into Indemnification Agreements with all of our
directors and executive officers providing for indemnification rights in some
circumstances. See "Management--Indemnification of Directors and Officers."

In August 1998, the holders of all of the outstanding shares of Keith
Engineering common stock contributed their shares to TKCI as a contribution to
capital. In consideration of this contribution, we issued to the contributing
shareholders one share of TKCI common stock for each share of Keith Engineering
stock contributed. Aram H. Keith, through the Aram H. Keith and Margie R. Keith
Trust, acquired 738,889 shares of TKCI common stock. Floyd S. Reid, as trustee
of the Floyd S. Reid and Ruth L. Reid Family Trust dated March 30, 1990,
acquired 351,852 shares of TKCI common stock. Mr. Keith is our President, Chief
Executive Officer and the Chairman of our board of our directors, and Mr. Reid
is a former director and executive officer of our company and remains a
principal shareholder.

On December 31, 1997, we borrowed $910,177 and $127,815 from Aram H. Keith and
Floyd S. Reid, respectively, under promissory notes. On June 3, 1998, we
borrowed an additional $300,000 from Mr. Keith. We have borrowed funds from Mr.
Keith from time to time as cash flow was needed. In February 1998, as a
condition to our credit agreement with Imperial Bank, subordination agreements
were executed by Messrs. Keith and Reid subordinating our payment obligations
to them under the notes to our obligations to Imperial Bank under our credit
agreement. The notes to Messrs. Keith and Reid were subsequently amended and
restated to include language which referenced these agreements and the two
separate notes to Mr. Keith were consolidated into a single note in the
principal amount of $1,210,177. Each of these notes provides for an interest
rate of 10% per annum and is due and payable in full on July 1, 2000. As of
March 31, 1999, we were indebted to Messrs. Keith and Reid under these notes,
including interest, in the respective amounts of $1,371,697 and $161,048.

In October 1997, we borrowed an aggregate of $213,782 from the Erica Keith
Educational Trust and the Susan E. Reid Housing Trust under two separate
promissory notes in the amounts of $129,205 and $84,577, respectively. The
obligees on these notes are trusts established for the benefit of the children
of Messrs. Reid and Keith. In February 1998, as a condition to our credit
agreement with Imperial Bank, subordination agreements were executed on behalf
of these trusts subordinating our payment obligations to the trusts under the
notes to our obligations to Imperial Bank under our credit agreement. Amended
and restated notes were executed in February 1999 to include accrued and unpaid
interest in the principal amounts, to extend the maturation dates and to
include language on the face of the notes to reference the subordination to our
obligations to Imperial Bank. The amended and restated notes to the Erica Keith
Educational Trust and the Susan E. Reid Housing Trust were in the amounts of
$132,000 and $86,000, respectively. These notes replaced the October 1997
notes. Each of these notes provides for an interest rate of 10% per annum and
is due and payable in full on October 30, 2000. As of March 31, 1999, we were
indebted to the obligees of these notes in the amounts of $134,134 and $87,390.

                                       61
<PAGE>

In April 1997, we entered into an Agreement for Advisory Services with Walter
W. Cruttenden, III, which provided that Mr. Cruttenden would provide us with
advice regarding strategic acquisitions and that Mr. Cruttenden, or a designee,
would serve on our board of directors. Mr. Cruttenden currently serves as a
director on our board of directors. In exchange for these services, we agreed
to pay Mr. Cruttenden $2,500 per quarter. In addition, for $10,000, we granted
Mr. Cruttenden options to purchase 10% of our outstanding common stock upon the
payment of additional consideration of $88,000. In July 1997, upon his exercise
of this option, we issued 325,926 shares of our common stock to Mr. Cruttenden,
at $.30 per share. The agreement also provides for indemnification by us and
Mr. Keith in some circumstances. Further, the agreement provides Mr. Cruttenden
with a right of first refusal to have Cruttenden Roth serve as the managing
underwriter in our initial public offering, which he waived in July 1998. The
agreement terminated on April 10, 1999.

In December 1997, Mr. Cruttenden and members of his family purchased 196,745
shares of TKCI common stock for an aggregate purchase price of $500,000, or
$2.54 per share.

In connection with the grant of options and sale of stock to Mr. Cruttenden,
$172,000 and $34,000 were recorded as common stock and stock compensation
expense in April 1997 and December 1997, respectively, representing the
difference between the exercise price at which the options were granted and the
price at which the stock was sold, and the estimated fair value of TKCI's stock
at the date of grant and sale, respectively. The price and other terms of these
stock sales was negotiated at arms length by Mr. Cruttenden and us, with each
of us acting solely on our own behalf.

In April 1997, we borrowed $700,000 from Mr. Cruttenden under a Secured
Promissory Note Line of Credit. In February 1999, the note to Mr. Cruttenden
was amended and restated to provide for its subordination to our obligations to
Imperial Bank. This note, as amended, provides for an interest rate of 10% per
annum and becomes fully due and payable on July 1, 2000. As of March 31, 1999,
our obligations under the note were $700,000. In conjunction with the note, we
entered into a Security Agreement with Mr. Cruttenden, Keith Engineering and
Mr. Keith, granting to Mr. Cruttenden a security interest in all of our assets
to secure the repayment of the amounts due under the note. Mr. Keith personally
guaranteed our obligations under the note. The note also provides that our
indebtedness to Mr. Keith and Mr. Reid under their December 31, 1997 notes are
subordinate to our obligations under the note.

In February 1997, Keith International borrowed $100,000 from Douglas Travato
under a promissory note. Mr. Travato is a personal friend of Mr. Keith and is
not an affiliate of the company. In February 1998, Mr. Keith assumed in writing
the Travato note and fully paid all amounts due under the note by transferring
55,556 shares of Mr. Keith's TKCI common stock to the Travato Family Trust. We
entered into a promissory note dated February 10, 1998 in favor of Mr. Keith in
the principal amount of $150,000, of which $100,000 reflected our obligation to
Mr. Keith in connection with his assumption of the Travato note, and the
additional $50,000 of which reflected our obligation to Mr. Keith in connection
with his assumption of a note with the Wyckoff Company Money Purchase Pension
Plan. In October

                                       62
<PAGE>

1998, we made a $150,000 cash payment to Mr. Keith in full satisfaction of our
obligations under our note to him. Keith International was a corporation owned
by Messrs. Keith and Reid that was dissolved in November 1998.

On February 26, 1996, Keith Engineering borrowed $50,000 from the Wyckoff
Company Money Purchase Pension Plan. In February 1997, the parties reduced this
loan to writing under a promissory note. The original maturity date of the loan
was August 26, 1996, which was successively extended to become fully due and
payable on February 26, 1998. In February 1998, Mr. Keith assumed the Wyckoff
note and fully paid all amounts due under the note by transferring to the
Wyckoff Company Profit Sharing Plan 18,519 shares of Mr. Keith's TKCI common
stock. In connection with this transaction, we entered into a promissory note
in favor of Mr. Keith in the principal amount of $150,000, of which $50,000
reflected our obligation to Mr. Keith resulting from his assumption of the
Wyckoff note. In October 1998, we made a $150,000 cash payment to Mr. Keith in
full satisfaction under our note to him.

In February 1998, Mr. Keith personally guaranteed the repayment of our
obligations under our credit agreement with Imperial Bank. The personal
guarantee of Mr. Keith was required by Imperial Bank as a condition to the
credit agreement. The only consideration for this guarantee was Mr. Keith's
equity interest in the company.

TKCI does not intend to engage in any additional transactions with management
and affiliates of the nature set forth in this "Certain Transactions" section
following the consummation of this offering, without the approval of its
independent board members.

In January 1988, Messrs. Keith and Reid entered into a Partnership Agreement
for the purpose of owning and administering investments made by them. This
agreement was amended in July 1992 to require Mr. Reid, after consultation with
Mr. Keith, to vote in concert with Mr. Keith.

                          DESCRIPTION OF CAPITAL STOCK

Our authorized capital stock consists of 100,000,000 shares of common stock,
$0.001 par value per share, and 5,000,000 shares of preferred stock, $0.001 par
value per share. Prior to June 22, 1999, TKCI's common and preferred stock had
no par value. This prospectus includes all material information relating to the
shares.

Common Stock
The holders of outstanding shares of our common stock are entitled to receive
dividends out of assets legally available therefor at times and in amounts as
the board of directors may, from time to time, determine, subordinate to any
preferences which may be granted to the holders of preferred stock and to some
restrictions on the payment of dividends contained in our credit agreement with
Imperial Bank. Holders of common stock are entitled to one vote per share on
all matters on which the holders of common stock are entitled to vote. The
common stock is not entitled to preemptive rights and may not be redeemed or
converted, except as may be provided by agreement. Upon liquidation,
dissolution or winding-up of TKCI, the assets legally available for
distribution to shareholders are divided among the holders of the common stock
in proportion to the number of shares of common stock held by each of them,
after payment of all of our debts and liabilities and the rights of any
outstanding class or series of preferred stock to have priority to distributed
assets. All outstanding shares of common stock are, and the shares of common
stock to be issued in this offering will be, when issued and delivered, validly
issued, fully paid and nonassessable. The rights, preferences and privileges of
holders of common stock are subordinate to any series of preferred stock that
we may issue in the future. As of March 31, 1999, there were 3,559,708 shares
of common stock outstanding held by 43 holders of record of which 74,074 are
subject to our obligation to redeem and are therefore classified as redeemable
securities. There are 1,111,111 shares of common stock reserved for issuance
under our Amended and Restated 1994 Stock Incentive Plan, of which an estimated
851,389 shares are issuable pursuant to outstanding options or will be issuable
pursuant to options to be granted prior to or upon the consummation of this
offering. There are also 83,333 shares of common stock issuable upon the
exercise of warrants granted in connection with the acquisitions of ESI,
Engineering Services Incorporated and John M. Tettemer & Associates, Ltd., and
up to 37,037 shares of common stock issuable if certain earnings targets and
other conditions are met by ESI. This does not include the shares which may be
issuable in connection with the acquisition of substantially all of the assets
and the assumption of certain of the liabilities of Thompson-Hysell.

Preferred Stock
Preferred stock may be issued from time to time in one or more series, and our
board of directors, without action by the holders of common stock, may fix or
alter the voting rights, redemption provisions, dividend rights, dividend
rates, claims to our assets superior to those of holders of our common stock,
conversion rights and any other rights, preferences, privileges and
restrictions of any wholly unissued series of preferred stock. The board of
directors, without shareholder approval, can issue shares of preferred stock
with rights that could adversely affect the rights of the holders of common
stock. No shares of preferred stock presently are outstanding, and we have no
present plans to issue any preferred shares.

                                       65
<PAGE>

The issuance of shares of preferred stock could adversely affect the voting
power of the holders of common stock and could have the effect of making it
more difficult for a third party to acquire, or could discourage or delay a
third party from acquiring, a majority of our outstanding stock.

Registration Rights

Following this offering, the shareholders of Thompson-Hysell will be entitled
to registration rights with respect to the shares they may receive in 2000. No
other persons have registration rights.

Transfer Agent and Registrar

The stock transfer agent and registrar for TKCI common stock is U.S. Stock
Transfer Corporation.

                        SHARES ELIGIBLE FOR FUTURE SALE

As of March 31, 1999, TKCI had outstanding 3,559,708 shares of common stock of
which 74,074 are subject to redemption provisions and are therefore classified
as redeemable securities. All of the shares sold in this offering will be
freely tradeable without restriction or further registration under the
Securities Act of 1933, unless held by an affiliate of TKCI within the meaning
of Rule 144 adopted under the Securities Act of 1933. Sales by any affiliate
would be limited by the resale limitations of Rule 144.

The shares of outstanding common stock that are not registered in this offering
will be "restricted securities" within the meaning of Rule 144 under the
Securities Act of 1933 and may not be sold in the absence of a registration
under the Securities Act of 1933 unless an exemption from registration is
available, including an exemption contained in Rule 144. In general, under Rule
144 as currently in effect, any person who has beneficially owned restricted
securities, as that term is defined in Rule 144, for at least one year is
entitled to sell, within any three-month period, a number of shares that does
not exceed the greater of (a) 1% of the then outstanding shares of our common
stock, or (b) the average weekly trading volume in our common stock during the
four calendar weeks preceding the sale, provided that public information about
us, as required by Rule 144, is then available and the seller complies with the
manner of sale and notification requirements of the rule. A person who is not
an affiliate and has not been an affiliate within three months prior to the
sale and has, together with any previous owners who were not affiliates,
beneficially owned restricted securities for at least two years is entitled to
sell those shares under Rule 144(k) without regard to any of the volume
limitations described above. As of March 31, 1999, 603,148 restricted shares
were eligible for sale under Rule 144(k). The remainder of the restricted
shares will be eligible for sale from time to time thereafter upon expiration
of one-year holding periods and once the other conditions of Rule 144 have been
met. In addition, the sale of shares held by all of our shareholders and
persons with rights to acquire our shares, except some non-management employees
and former shareholders of John M. Tettemer & Associates and ESI, is restricted
by lock-up agreements in favor of the representative of the underwriters which
become effective on the date of this offering for a period of 180 days.


                                       66
<PAGE>

Upon the consummation of this offering, we will have outstanding options to
purchase an estimated 851,389 shares of our common stock held by some of our
employees and directors under our Amended and Restated 1994 Stock Incentive
Plan. We intend to register on a registration statement on Form S-8, on or
shortly after the date of this prospectus, all of the estimated 851,389 shares
of common stock underlying the options that are then outstanding or issuable
under the Amended and Restated 1994 Stock Incentive Plan.

TKCI also has outstanding four warrants to purchase an aggregate of 83,333
shares of common stock granted in connection with the acquisitions of ESI and
John M. Tettemer & Associates. The shares issued upon exercise of those
warrants will be restricted securities. In connection with the acquisition of
ESI, if earnings goals and other conditions are met, TKCI has also agreed to
issue (a) up to 37,037 shares of TKCI common stock and (b) options to purchase
an additional 37,037 shares of common stock to employees of ESI. In connection
with the acquisition of Thompson-Hysell, TKCI will grant a warrant to purchase
66,667 shares of common stock to a finder and has agreed to (a) issue that
number of shares with a value of $1,333,334, subject to adjustment, to the
shareholders of Thompson-Hysell if earnings goals are met; and (b) reserve
options to purchase 37,037 shares of common stock for granting to those
employees of Thompson-Hysell who become employees of TKCI following this
offering. These shares, if issued, will be restricted securities but will
include the right to have the shares registered for resale under the Securities
Act of 1933.

No predictions can be made of the effect, if any, that future sales of shares
of our common stock, and grants of options and warrants to acquire shares of
our common stock, or the availability of shares for future sale, will have on
the market price of the common stock prevailing from time to time. Sales of
substantial amounts of common stock in the public market, or the perception
that these sales could occur, could adversely affect the prevailing market
prices of the common stock. See "Principal Shareholders," "Description of
Capital Stock" and "Underwriting."

</TABLE>

The underwriting agreement provides that the obligations of the several
underwriters to purchase shares of common stock is conditional. If any of the
shares of common stock are purchased by the underwriters according to the
underwriting agreement, at least 1,500,000 shares of common stock must be
purchased.

Prior to this offering, there has been no established trading market for our
common stock. The initial price to the public for our common stock offered in
this prospectus will be determined by negotiation between the representative
and us. The factors to be considered in determining the initial price to the
public include the history of and the prospects for the industry in which we
compete, the performance and ability of our management, our past and present
operations, our historical results of operations, our prospects for future
earnings, the general condition of the securities markets at the time of this
offering and the recent market prices of securities of generally comparable
companies. The estimated initial public offering price range set forth on the
cover page of this prospectus may change as a result of market conditions and
other factors.

The underwriters propose to offer the shares of common stock directly to the
public at the offering price set forth on the cover page of this prospectus,
and to some dealers, including the underwriters at that price less a concession
not in excess of $0.35 per share. Any dealers or agents that participate in the
distribution of the common stock may be deemed to be underwriters within the
meaning of the Securities Act of 1933, and any discounts, commission or
concessions received by them and any resulting from the sale of the shares by
them might be deemed to be underwriting discounts and commissions under the
Securities Act of 1933. TKCI has agreed to pay the representative a non-
accountable

                                       68
<PAGE>

expense allowance of 1% of the proceeds of this offering. After the public
offering of the shares, the offering price and other selling terms may be
changed by the underwriters.

The offering is being conducted in accordance with Rule 2720 of the National
Association of Securities Dealers, Inc. which provides that, among other
things, when a member of the National Association of Securities Dealers, Inc.
participates in the offering of equity securities of a company with whom such
member has an "affiliation" (as defined in Rule 2720), the initial public
offering price can be no higher than that recommended by a "qualified
independent underwriter" (as defined in Rule 2720). Because Mr. Cruttenden owns
more than 10% of TKCI's outstanding common stock and controls E*OFFERING Corp.,
one of the underwriters in this offering, he is deemed to have such an
affiliation with TKCI that requires that the offering be managed by a qualified
independent underwriter. Accordingly, Wedbush Morgan Securities, Inc. is
serving as the qualified independent underwriter in the offering and has
recommended a price in compliance with the requirements of Rule 2720. Wedbush
Morgan Securities, Inc. has performed due diligence investigations and reviewed
and participated in the preparation of this prospectus and the registration
statement of which this prospectus forms a part. Wedbush Morgan Securities,
Inc., in its capacity as a qualified independent underwriter, will receive no
additional compensation as such in connection with the offering.

A prospectus in electronic format is being made available on an Internet
website maintained by E*TRADE Securities, Inc. at www.etrade.com. A prospectus
in electronic format is also being made available on an Internet website
maintained by Wedbush Morgan Securities, Inc., E Investmentbank at
www.einvestmentbank.com. E Investmentbank is the online investment bank of
Wedbush Morgan Securities, Inc., which provides its investors access to initial
public offerings, secondary offerings and private placements. Except for this
prospectus, nothing on either of these web sites shall be deemed to be a part
of this prospectus.

We have agreed to indemnify the underwriters against some civil liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments that the underwriters may be required to make in respect thereof.

TKCI, and each of its directors and executive officers, and many of its
shareholders, option, warrant and rights holders have agreed not to offer, sell
contract to sell or otherwise dispose of any shares of common stock or any
securities convertible into or exercisable or exchangeable for common stock, or
in any manner transfer all or a portion of the economic consequences associated
with the ownership of their common stock, or to cause a registration statement
covering any shares of common stock to be filed, for 180 days after the date of
the underwriting agreement without the prior written consent of the
representative. We may grant options as contemplated by, and issue shares of
common stock upon the exercise of options under our Amended and Restated 1994
Stock Incentive Plan. See "Shares Eligible for Future Sale."

TKCI has granted to the underwriters an option to purchase up to an aggregate
of 225,000 additional shares of our common stock, at the initial public
offering price less underwriting discounts and commissions, solely to cover
over-allotments. This option may be exercised in whole or in part from time to
time during the 45-day period after the date of this prospectus.

                                       69
<PAGE>

To the extent that the underwriters exercise this option, each of the
underwriters will be committed, with some exceptions, to purchase from us a
number of option shares proportionate to each underwriter's initial commitment
as indicated in the preceding table.

The following table shows the underwriting fees to be paid to the underwriters
by us in connection with this offering. These amounts are shown assuming both
no exercise and full exercise of the underwriters' option to purchase
additional shares of common stock.

</TABLE>

We estimate that our share of the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $1,342,000.

In the event our common stock does not constitute an excepted security under
the provisions of Regulation M promulgated by the Securities and Exchange
Commission, the underwriters and dealers may engage in passive market making
transactions in accordance with Rule 103. In general, a passive market maker
may not bid for or purchase shares of common stock at a price that exceeds the
highest independent bid. In addition, the net daily purchase made by any
passive market maker generally may not exceed 30% of its average daily trading
volume in the common stock during a specified two-month prior period, or 2000
shares, whichever is greater. A passive market maker must identify which bids
are passive market making bids on the Nasdaq electronic later-dealer reporting
system. Passive market making may stabilize or maintain the market price of the
common stock above independent market levels. Underwriters and dealers are not
required to engage in passive market making and may end passive market making
activities at any time.

In connection with this offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot this offering, creating a
syndicate short position. In addition, the underwriters may bid for and
purchase shares of our common stock in the open market to cover syndicate short
positions or to stabilize the price of our common stock. These activities may
stabilize or maintain the market price of our common stock above independent
market levels. The underwriters are not required to engage in these activities
and may end any of these activities at any time.

We have applied for the listing of our common stock on the Nasdaq National
Market under the symbol "TKCI."

The representative has informed us that the underwriters do not intend to
confirm sales to accounts over which they exercise discretionary authority.

                                 LEGAL MATTERS

passed upon for us by Rutan & Tucker, LLP, Costa Mesa, California. Cooley

obligations and notes payable to related parties with the net proceeds of the
offering had all occurred on January 1, 1998.

The pro forma adjustments are based upon currently available information and
upon certain assumptions that we believe are reasonable. There can be no
assurances that the actual effect will not differ significantly from the pro
forma adjustments reflected in the pro forma condensed consolidated financial
statements.

The pro forma condensed consolidated financial statements should be read in
conjunction with the consolidated financial statements of TKCI and its
subsidiaries, and the notes thereto, and the financial statements of Thompson-
Hysell, and the notes thereto, included elsewhere in this prospectus. The pro
forma condensed consolidated financial statements do not purport to represent
our financial position as of March 31, 1999 or the results of operations for
the year ended December 31, 1998 or the three months ended March 31, 1999 that
would actually have occurred had the initial public offering of 1,500,000
shares of common stock, at an assumed initial public offering price of $9.00
per share; the acquisition of substantially all of the assets and the
assumption of certain of the liabilities of Thompson-Hysell; and the repayment
of debt, capital lease obligations and notes payable to related parties with
the net proceeds of the offering had all occurred on March 31, 1999 or on
January 1, 1998, or to project our financial position or results of operations
as of any future date or for any future period.

Adjustments to the Pro Forma Condensed Consolidated Balance Sheet

The pro forma adjustments to the Pro Forma Condensed Consolidated Balance Sheet
as of March 31, 1999 are as follows:

(a)  Acquisition of substantially all of the assets and assumption of
     substantially all of the liabilities of Thompson-Hysell for total
     consideration of cash of $3,333 and contingent consideration consisting of
     a note payable, common stock and additional cash (which are subject to
     certain contingencies further described below). The acquisition is
     accounted for using purchase accounting, in which the purchase price is
     allocated based upon the estimated fair value of assets acquired and
     liabilities assumed, which approximates book value:

  Assets and liabilities which will not be acquired or assumed, and a line
  of credit balance to be drawn on by Thompson-Hysell to repay those
  liabilities not assumed by TKCI:
     Cash.............................................................. $   264
     Other assets......................................................     243
     Line of credit to be assumed......................................      95
     Accrued liabilities to related parties............................     (23)
     Notes payable to related parties..................................    (579)
</TABLE>
  The acquisition of substantially all of the assets and the assumption of
  substantially all of the liabilities of Thompson-Hysell results in a
  purchase price of $3,333 in cash. Contingent consideration consists of
  $1,333 in a note payable and $1,333 in common stock. In addition, TKCI may
  be obligated or entitled to pay or receive cash related to financial
  targets and pay cash related to the income tax effects to the sellers. The
  note payable will be issued at closing, but may be adjusted based on an
  earnings target in 2000. The common stock may or may not be issued
  depending upon whether earnings before interest and taxes exceeds $1,800
  in 1999. Due to the financial targets assumed to be met and

  assumed income tax effects to the sellers, TKCI made a pro forma adjustment
  for the payment of cash of $500 and $525, respectively. Due to the assumed
  issuance of the note payable, TKCI made a pro forma adjustment for the debt
  issued. Due to the uncertainty surrounding the 1999 earnings target, TKCI
  excluded the contingent issuance of common stock. Refer to "Acquisition"
  for further discussion of the contingent consideration.

(b)  Sale of 1,500,000 shares of common stock at an assumed initial public

                          Independent Auditors' Report

The Board of Directors and Stockholders
The Keith Companies, Inc.:

We have audited the accompanying consolidated balance sheets of The Keith
Companies, Inc. and subsidiaries (note 1) as of December 31, 1997 and 1998, and
the related consolidated statements of income, stockholders' equity (deficit),
and cash flows for each of the years in the three-year period ended December
31, 1998. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of The Keith
Companies, Inc. and subsidiaries as of December 31, 1997 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1998, in conformity with generally
accepted accounting principles.

           and Three Months Ended March 31, 1998 and 1999 (Unaudited)

(1) Organization and Basis of Presentation

The Keith Companies, Inc. (formerly The Keith Companies--Inland Empire, Inc.)
("TKCI") was incorporated in the State of California in November 1986. Keith
Engineering, Inc. ("KEI") was incorporated in the State of California in March
1983. The Keith Companies--Hawaii, Inc. ("TKCH"), a wholly-owned subsidiary of
TKCI, was incorporated in the state of Hawaii on January 4, 1989. TKCH no
longer maintains an office in Hawaii and had minimal operations in 1996, 1997,
1998 and 1999. In December 1997, TKCI acquired Engineering Services
Incorporated, and its wholly-owned subsidiary Engineered Systems Integrated,
Inc. (which was merged with Engineering Services Incorporated on August 1,
1998) (collectively, "ESI"). In addition, in August 1998, TKCI acquired John M.
Tettemer and Associates, Inc. ("JMTA").

TKCI and KEI have been under common management since inception. TKCI and KEI
were under common control as a result of a contemporaneous written agreement
dated July 1992 between their majority shareholders. This agreement provided
for the shareholders to vote in concert and thus the majority shareholders
became a common control group. On August 1, 1998, TKCI acquired all of the
outstanding common stock of KEI (the "Reorganization") by a contribution to
capital of TKCI by KEI's shareholders of all of the outstanding stock of KEI in
exchange for the issuance by TKCI of an equal number of shares of its stock. On
November 30, 1998, KEI, a wholly owned subsidiary of TKCI, was merged with and
into TKCI, and its outstanding shares, all of which were then owned by TKCI,
were cancelled as a result of the merger. The Reorganization was accounted for
as a combination of affiliated entities under common control in a manner
similar to a pooling-of-interests. Under this method, the assets, liabilities
and equity of TKCI and KEI were carried over at their historical book values
and their operations prior to the Reorganization have been recorded on a
combined historical basis. The combination did not require any material
adjustments to conform the accounting policies of the separate entities. As a
result of the Reorganization, the accompanying financial statements include the
consolidated assets, liabilities, equity and results of operations of TKCI,
KEI, ESI, JMTA and TKCH effective August 1, 1998 (see Note 2).

TKCI and its wholly-owned subsidiaries (the "Company") is a leading provider of
engineering, consulting and technical services. The Company primarily serves
clients in the real estate development, public works and wireless
telecommunications and industrial engineering industries, pursuant to short and
long-term construction type contracts principally in California and Nevada. The
Company specializes in the planning, engineering, permitting and other services
essential to create and build infrastructure for a wide range of real estate
development and public works projects and provides site acquisition and
construction management services for the wireless telecommunications industry.
In addition, the Company

provides a complete array of industrial engineering services required to design
and test automated processes, manufacturing production lines and fire
protection systems.

Services offered by the Company include civil engineering, surveying and
mapping, planning, environmental, archaeological, construction management, site
acquisition, water resource engineering, instrumentation and control systems
engineering, fire protection engineering, electrical engineering, mechanical
engineering and chemical process engineering. The Company's clients include
real estate developers, residential and commercial builders, architects,
cities, counties, water districts, local and federal agencies, universities,
retailers, cellular phone service providers and manufacturers of a variety of
products.

(2) Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of
TKCI, KEI, ESI, JMTA and TKCH (see Note 1). All material intercompany
transactions and balances have been eliminated in consolidation.

Revenue and Cost Recognition on Engineering Contracts

The Company enters into fixed fee contracts and contracts that provide for fees
on a time- and-materials basis, most of which have not to exceed provisions.
Contracts typically vary in length between six months and three years. However,
many contracts are for small increments of work, which can be completed in less
than six months. Revenue is recognized on the percentage of completion method
of accounting based on the proportion of actual contract costs incurred to
total estimated contract costs. Management considers costs incurred to be the
best available measure of progress on the contracts.

In the course of providing its services, the Company sometimes subcontracts for
various services like landscape architecture, architecture, geotechnical
engineering, structural engineering, traffic engineering, and aerial
photography. These costs are included in the billings to the clients and, in
accordance with industry practice, are included in the Company's gross revenue.
Because subcontractor services can change significantly from project to
project, changes in gross revenue may not be indicative of business trends.
Accordingly, the Company also reports net revenue, which is gross revenue less
subcontractor costs.

Costs of revenue include labor, nonreimbursable subcontract costs, materials
and some direct and indirect overhead costs like rent, utilities and
depreciation. General and administrative costs are charged to expense as
incurred. Provisions for estimated losses on uncompleted

             Three Months Ended March 31, 1998 and 1999 (Unaudited)

(2) Summary of Significant Accounting Policies (continued)

contracts are made in the period in which the losses are determined. Changes in
job performance, job conditions and estimated profitability, including final
contract settlements, may result in revisions to costs and income and are
recognized in the period in which the revisions are determined. Additional
revenue resulting from requests for additional work due to changes in the scope
of engineering services to be rendered, are included in revenues when
realization is probable and can be estimated with reasonable certainty.

Costs and estimated earnings in excess of billings represents revenue
recognized in excess of amounts billed on the respective uncompleted
engineering contracts. Billings in excess of costs and estimated earnings
represents amounts billed in excess of revenue recognized on the respective
uncompleted contracts.

At December 31, 1997, 1998 and March 31, 1999 (unaudited), the Company had no
significant amounts included in contracts and trade receivables or trade
accounts payable representing amounts retained pending contract or subcontract
completion.

Equipment and Leasehold Improvements

Equipment and leasehold improvements are stated at cost or, in the case of
leased assets, the lesser of the present value of future minimum lease payments
or fair value. Depreciation is provided on a straight-line basis over the
estimated useful lives of the assets, or, in the case of capital leased assets,
over the lease term if shorter, as follows:

<TABLE>
       <S>                                                        <C>
       Equipment................................................. 5 to 10 years
       Leasehold Improvements.................................... 1 to 10 years
</TABLE>

When assets are sold or otherwise retired, the related cost and accumulated
depreciation are removed from the accounts and the resulting gain or loss is
included in other expenses (income), net in the accompanying consolidated
statements of income.

Income Taxes and Pro Forma Supplemental Data

Prior to August 1, 1998, KEI, with the consent of its stockholders, elected to
be taxed as an S corporation under the Internal Revenue Code of 1986, as
amended. As an S corporation, corporate income or loss flows through to the
stockholders who are responsible for including the income, deductions, losses
and credits in their individual income tax returns. Accordingly, prior to
August 1, 1998, no provision for federal or state income taxes for KEI is
included in the accompanying consolidated financial statements, except for
California income taxes at the greater of $800 or the S corporation rate of
1.5% of taxable income. As a result of the Reorganization, KEI no longer
qualified to be taxed as an S corporation and effective August 1, 1998, its
operations were included in the consolidated C corporation tax return of the
Company.

TKCI, ESI, JMTA and TKCH are C corporations and account for income taxes, under
the asset and liability method, in accordance with Statement of Financial
Accounting Standards

(2) Summary of Significant Accounting Policies (continued)

("SFAS") No. 109, "Accounting for Income Taxes," which requires recognition of
deferred tax assets and liabilities for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carry forwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.


Historical pro forma supplemental data are unaudited and are presented as if
the Company had been taxed as a C corporation for the periods presented. The
pro forma tax provision has been calculated assuming a 42% combined effective
tax rate.

Goodwill

Goodwill, which represents the excess of purchase price over fair value of net
assets acquired, is amortized on a straight-line basis over the expected
periods to be benefited, generally 25 years. The Company assesses the
recoverability of goodwill by determining whether the amortization of the
goodwill balance over its remaining life can be recovered through undiscounted
future operating cash flows of the acquired operation. The amount of goodwill
impairment, if any, is measured based on projected discounted future operating
cash flows using a discount rate reflecting the Company's average cost of
funds. The assessment of the recoverability of goodwill will be impacted if
estimated future operating cash flows are not achieved. Amortization expense
related to goodwill totaled $10,000 and $5,000 (unaudited) for the year ended
December 31, 1998 and the three months ended March 31, 1999, respectively.

Stock Options

The Company accounts for its stock options in accordance with the provisions of
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock
Issued to Employees," and related interpretations. Compensation expense is
recorded on the date of grant only if the current market price of the
underlying stock exceeds the exercise price. SFAS No. 123, "Accounting for
Stock Based Compensation," permits entities to recognize the fair value of all
stock-based awards on the date of grant as expense over the vesting period.
Alternatively, SFAS No. 123 allows entities to continue to apply the provisions
of APB Opinion No. 25 and provide pro forma net income disclosures for employee
stock option grants made in 1995 and future years as if the fair-value-based
method defined in SFAS No. 123 had been applied. The Company has elected to
continue to apply the provisions of APB Opinion No. 25 and provide the pro
forma disclosure provisions of SFAS No. 123.

Deferred Offering Costs

The Company expects to complete an initial public offering during 1999. Most of
the related costs incurred have been deferred and included in the accompanying
1997, 1998 and 1999 consolidated balance sheets as deferred offering costs.
Should the Company decide not to consummate the offering, these costs would
then be expensed.

Stock Split

On April 23, 1999, the board of directors authorized a 2.70-for-1 reverse split
of TKCI's common stock, effective April 26, 1999. All share amounts in the
accompanying consolidated financial statements (except for shares of authorized
common stock) have been restated to give effect to the stock split.

Per Share Data

Basic EPS is computed by dividing earnings available to common stockholders
during the period by the weighted average number of common shares outstanding
during each period. Diluted EPS is computed by dividing earnings available to
common stockholders during the period by the weighted average number of shares
that would have been outstanding assuming the issuance of common shares for all
dilutive potential common shares outstanding during the reporting period, net
of shares assumed to be repurchased using the treasury stock method.

The following is a reconciliation of the denominator for the basic EPS
computation to the denominator of the diluted EPS computation. Net income
available to common stockholders is used in the basic and diluted EPS
calculations as the assumed impact of the redeemable securities would be anti-
dilutive.

Interim Financial Statements

The accompanying consolidated balance sheet as of March 31, 1999 and the
statements of income and cash flows for the three months ended March 31, 1998
and 1999, and the statement of stockholders' equity for the three months ended
March 31, 1999 are unaudited and have been prepared on the same basis as the
audited consolidated financial statements included herein. In the opinion of
management, these unaudited consolidated financial statements include all
adjustments necessary to present fairly the information set forth therein,
which consist solely of normal recurring adjustments. The results of operations
for these interim periods are not necessarily indicative of results for the
full year.

Use of Estimates in the Preparation of Consolidated Financial Statements

The preparation of these consolidated financial statements, in conformity with
generally accepted accounting principles, requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the amounts of revenue and expenses reported during
the periods. Actual results may differ from the estimates and assumptions used
in preparing these consolidated financial statements.

Reclassifications

Certain 1996 and 1997 balances have been reclassified to conform to the
presentation used in 1998.

(3) Acquisitions

John M. Tettemer & Associates, Inc.

On August 1, 1998, TKCI acquired all of the outstanding common stock of JMTA
for $700,000, which consisted of cash of $150,000; $300,000 in amortizing notes
bearing interest at 8% payable in 60 monthly payments; $250,000 in interest
only notes bearing interest at 8% payable quarterly, due the sooner of the
first anniversary date of the purchase agreement or the date the Company closes
its anticipated initial public offering; and warrants to purchase 55,556 shares
of TKCI common stock, exercisable immediately at a purchase price of $4.73 per
share, expiring July 31, 2003. The fair value of the warrants, calculated using
the Black-Scholes option pricing model assuming an estimated fair value of
common stock at issue date of $3.78 per share, a risk free interest rate of 5%
and no stock dividend yield, was immaterial and therefore excluded from the
purchase price. The amortizing and interest only notes include the principal
stockholder of TKCI as co-maker. The amortizing notes are subject to an
adjustment based on a calculation tied to the JMTA book value at

(3) Acquisitions (continued)

August 1, 1998. The acquisition was accounted for using the purchase method of
accounting and, accordingly, the consolidated financial statements include the
assets and liabilities and results of operations of JMTA as of and subsequent
to August 1, 1998. The excess purchase price over the fair value of the net
identified assets acquired, including acquisition costs of $100,000, totalled
$631,000 and has been recorded as goodwill in the accompanying December 31,
1998 consolidated balance sheet.

During 1999, the purchase price allocation was revised to reflect an adjustment
to the JMTA book value at August 1, 1998. The purchase price allocation
revision resulted in a $60,000 (unaudited) adjustment to decrease goodwill and
long-term debt in the accompanying March 31, 1999 consolidated balance sheet.

ESI, Engineering Services Incorporated

On December 30, 1997, TKCI acquired all of the outstanding common stock of ESI,
Engineering Services Incorporated, and its wholly-owned subsidiary Engineered
Systems Integrated, Inc., in exchange for 74,074 shares of TKCI common stock
valued at $2.70 per share. The acquisition was accounted for using the purchase
method of accounting and accordingly, the consolidated financial statements
include the assets and liabilities and results of operations of ESI as of and
subsequent to December 30, 1997.

The purchase agreement contains a provision whereby TKCI, must, at the sole
discretion of the seller, repurchase any or all of the seller's portion of the
74,074 shares issued for a price of $6.75 per share, if the Company does not
complete an initial public offering by October 31, 1999. This right of the
seller expires November 15, 1999. Both dates are automatically extended under
some circumstances. Under some circumstances, the Company must also repurchase
stock options granted in connection with the acquisition of ESI (see note 8).
The fair value of the stock options, calculated using the Black-Scholes option
pricing model assuming an estimated fair value of common stock at issue date of
$2.70 per share, a risk-free interest rate of 6% and no stock dividend yield,
was immaterial and therefore excluded from the purchase price. TKCI's officers
and/or stockholders have agreed, with ESI's former shareholders, to subordinate
repayment of debt owed to them up to an amount, when the principal portion of
the debt owed to the stockholders is netted with the book value of TKCI's
equity, equals $750,000. Further, an additional 37,037 shares of TKCI common
stock may be issued to the prior ESI owners subject to attainment of
performance criteria tied to minimum net income per share requirements (as
defined in the purchase agreement) for the fiscal years 1998, 1999 and 2000.
The minimum net income per share requirement is based on the average of the
number of shares issued and options granted to current and future employees of
ESI at the beginning of each quarter for the fiscal years 1998, 1999 and

conditions, the fair value of the additional shares will be recorded as an
additional cost of the net assets acquired. As of March 31, 1999, none of the

In addition, the ESI purchase agreement provides for an anti-dilution provision
whereby TKCI may not issue additional shares of stock without the sellers'
consent; except as may be
required to comply with the terms of the ESI agreement, to issue shares in
connection with future acquisitions, to provide additional shares for Incentive
Stock Option Plans, or for the contemplated initial public offering by TKCI.

(5) Indebtedness

The Company's short-term borrowings and long-term debt, some of which prohibit
payment of dividends, are substantially all guaranteed by the principal
stockholder of TKCI.

Short-Term Borrowings

The Company had a consolidated and restated credit agreement, as amended in
December 1996 and September 1997, which allowed the Company to borrow up to
$10,500,000 at the bank's prime rate plus 3.25%, with all unpaid principal and
interest due on March 1, 1998. The bank's prime rate at December 31, 1997 was
8.5%. The credit agreement was collateralized by accounts receivable and UCC-1
filing on tangible assets and was guaranteed by TKCI's principal stockholder.
As of December 31, 1997, the Company owed $2,683,000 and $27,000 in principal
and accrued interest, respectively, under this line of credit.

On February 9, 1998, the Company obtained a new line of credit from a bank and
used the proceeds to repay all amounts due under its previous consolidated and
restated credit agreement. This new line of credit agreement, which was to
expire on April 30, 1999, contained positive and negative covenants of both a
financial and nonfinancial nature, as amended. As a result of the Company's
demonstrated ability and intent to refinance the short-term obligation on a
long-term basis, borrowings under the previous line of credit at December 31,
1997 were classified as long-term in the accompanying consolidated balance
sheet.

The new line of credit permitted the Company to borrow up to $5,000,000, but
not in excess of 75% of eligible accounts receivable as defined in the
agreement. The interest rate is at the bank's prime rate plus 1.5% (9.25% at
December 31, 1998), payable monthly, with the principal maturing one year from
the date of the agreement. The line of credit is collateralized by a first-
priority perfected security interest in all assets of the Company and is
guaranteed by TKCI's principal stockholder.

The new line of credit agreement was amended in March 1998, June 1998 and
October 1998 to, among other things, add ESI and JMTA as co-borrowers on the
agreement, increase the percentage of eligible receivables to 80%, increase the
amount available to borrow to $5,500,000, extend the maturity on the line to
April 30, 1999 and amend some financial related covenants. As of September 30,
1998, the Company was in default of some financial related covenants. On March
5, 1999, the bank waived compliance related to these covenants as of September
30, 1998. In addition, the bank further amended the agreement to, among other
things, amend some financial related covenants as of December 31, 1998, adjust
the interest rate to the bank's prime rate plus a variable margin tied to
financial covenants (10.5% at March 5, 1999) and extend the maturity on the
line to March 1, 2000. As a result of the Company's demonstrated ability and
intent to refinance the short-term obligation on a long-term basis, the
outstanding borrowings under the line of credit of $4,527,000 as of December
31, 1998 are classified as long-term in the accompanying consolidated balance

accompanying consolidated balance sheet.

On December 30, 1997, the Company acquired ESI, which had a line of credit with
a commercial bank in the amount of $1,250,000, bearing interest at the bank's
reference rate plus 1.25% (9.75% at December 31, 1997), subject to periodic
adjustment. As of December 31, 1997, the Company had an outstanding balance of
$310,000 on this line of credit. On January 6, 1998, the outstanding balance
was paid off and the line of credit was terminated.

(a) TKCI and its affiliates, as specified in the agreement, and KEI's majority
stockholder entered into a settlement agreement and mutual release on November
14, 1995 related to the default by KEI on payment of rent and other amounts due
under a lease. The Company agreed to pay the sum of $1,490,000, of which
$140,000 was paid upon execution of the agreement and $1,350,000 was payable
under the terms of a promissory note. The obligations under the promissory note
are collateralized by a judgment of $1,800,000, less any amounts previously
paid under the agreement, not to be executed unless and until an event of
default has occurred, as defined. The promissory note, as amended, required a
$300,000 payment in November 1996 and monthly payments of $12,000, until paid
in full. The $300,000 payment due in November 1996 was renegotiated and paid in
three $100,000 payments in November 1996, March 1997 and June 1997. The monthly
payments for a particular calendar quarter are to be increased, in the event
that consolidated sales of TKCI and its affiliates, as specified in the
agreement, exceed $5,000,000 in the previous calendar quarter. The increase is
proportional to the percentage by which quarterly sales exceed $5,000,000. In
1998, the Company made additional principal payments of $47,000 related to this
provision.

Future annual principal maturities of long-term debt (including short-term
borrowings refinanced as long-term-debt) as of December 31, 1998 are as

(6) Notes Payable to Related Parties

Notes payable to related parties consist of unsecured borrowings, for operating
purposes, of $1,395,000 and $1,701,000 at December 31, 1997 and 1998,
respectively, from the principal stockholders and parties related to the
Company's stockholders. Interest only payments at 10% per annum are due
quarterly on each January 1, April 1, July 1, and October 1, commencing on
April 1, 1998. Accrued interest at December 31, 1997 and 1998 related to these
notes was $116,000 and $185,000, respectively. These notes mature on July 1,
2000, with all the outstanding principal and unpaid interest then due, and are
subordinate to the line of credit obtained from the Company's primary bank in
February 1998 (see note 5).

(6) Notes Payable to Related Parties (continued)

In February 1996 and 1997, $50,000 and $100,000, respectively, were loaned to
the Company by two related parties in exchange for promissory notes bearing
interest at 10%. These notes were subsequently amended to extend the due dates
to February 1998. In February 1998, agreements were entered into whereby the
notes were assigned to the principal stockholder of TKCI in exchange for shares
of TKCI common stock, which the principal stockholder owns personally. The old
notes were subsequently cancelled and a new note was created for $150,000, with
a maturity date of January 15, 2000 and bearing interest at 10% payable
quarterly. As a result of the Company's demonstrated ability and intent to
refinance the short-term obligations on a long-term basis, the Company has
recorded the above loans in the amounts of $50,000 and $100,000, respectively,
as long-term notes payable to related parties in the December 31, 1997
consolidated balance sheet. This note was paid in full along with all accrued
interest in October 1998.

In April 1997, the Company entered into a collateralized promissory note
agreement, which was amended in December 1997, for working capital purposes
with a related party in the principal amount of $700,000. Interest on the note
accrues at a rate of 10% per annum and is payable on each of January 1, April
1, July 1 and October 1, commencing April 1, 1998. The note matures on July 1,
2000 with all the outstanding principal and unpaid interest then due. The note
is collateralized by all property of the Company, as defined in the agreement,
and is subordinate to the line of credit obtained from the Company's primary
bank in February 1998. This related party also received an option to purchase
common stock in the Company (see note 9).

Principal payments due to related parties of $2,401,000 are due in 2000.

(7) Leases

The Company leases equipment and vehicles under capital lease agreements that
expire at various dates through 2002.

The Company also has several noncancelable operating leases, primarily for
office facilities, that expire through 2004. These leases generally contain
renewal options for periods ranging from one to five years and require the
Company to pay costs, like common area maintenance and insurance charges.
Rental expense for operating leases during 1996, 1997 and 1998 totaled
$1,190,000, $1,183,000 and $1,671,000, respectively.

(8) Redeemable Securities

In connection with the acquisition of ESI, TKCI issued to the sellers 74,074
shares of common stock, redeemable at the discretion of any seller at a price
of $6.75 per share, if the Company does not complete an initial public offering
by October 31, 1999. This right of the sellers expires November 15, 1999. Both
dates are automatically extended under certain conditions. The redeemable
common stock was valued at $2.70 per share on the date of the acquisition of
ESI. The difference between the redemption value of $6.75 per share and the
initial valuation of $2.70 per share is accreted over the period from the
acquisition, December 30, 1997, through October 31, 1999 through charges to
common stock. Upon the completion of the anticipated initial public offering
prior to October 31, 1999, the accumulated accretion and the redeemable
securities would be reclassified to common stock.

In connection with the acquisition of ESI, TKCI issued to the sellers options
to purchase 44,444 shares of common stock with redemption provisions. The
redemption provisions provide that in the event that the underlying shares do
not have a fair market value of at least $8.10 per share at some time during
the period between the date of the anticipated initial public offering and
October 1, 2002, the holders are entitled to receive $5.40 in cash

for each unexercised vested option (or $8.10 for each share of common stock
issued upon exercise of an option). The $5.40 redemption value is accreted over
the period from the acquisition, December 30, 1997 through October 1, 2002
through charges to common stock. Upon the completion of the anticipated initial
public offering, the accumulated accretion would be reclassified to common
stock.

(9) Common Stock

All issued and outstanding shares of KEI prior to the Reorganization were
exchanged into an equivalent number of shares of TKCI and all of the shares of
KEI were subsequently cancelled. The outstanding shares of TKCI prior to the
Reorganization remained outstanding and were not affected by the
Reorganization.

In April 1997, an option to purchase 10% of the Company's outstanding common
stock (calculated after the option purchase) was granted to an unrelated party
for $10,000. The option was exercised in July 1997, for $88,000, resulting in
the issuance of 325,926 shares. Once becoming a 10% stockholder as a result of
this option exercise, the option holder became a related party. On December 31,
1997, an additional 196,745 shares of the Company's stock were purchased by
this related party for $500,000. In connection with the grant of options and
sale of stock to this related party, a total of $206,000 was recorded as common
stock and stock compensation expense, representing the difference between the
exercise price at which the options were granted and the price at which the
stock was sold, and the estimated fair value of the Company's stock at the date
of grant and sale, respectively. The related party was also granted a position
on the Company's board of directors. In April 1997, the Company also entered
into a collateralized promissory note agreement with this related party for
$700,000 (see note 6).

officers and key employees. The Plans, as amended in 1997, authorized grants of
options to purchase 555,556 shares of authorized but unissued common stock in
TKCI and KEI. Stock options have been granted with an exercise price equal to
or greater than the stock's estimated fair market value at the date of grant.
All stock options issued in connection with the Plans have ten-year terms and
vest and become exercisable ratably each year for the first five years from the
grant date.

In connection with the Reorganization, the KEI plan was terminated and options
to purchase shares of common stock of KEI outstanding at August 1, 1998 were
automatically converted into options to purchase a like number of shares of
TKCI common stock, with the same exercise price, expiration date and other
terms as prior to the Reorganization (the "Plan").

At December 31, 1998, there were options to acquire 70,000 shares available for
grant under the Plan. The following represents the estimated fair value of
options granted, as determined using the Black-Scholes option pricing model and
the assumptions used for calculation:

In accounting for its Plans, the Company elected the pro forma disclosure
option under SFAS No. 123. Accordingly, no compensation cost has been
recognized for its stock options in the consolidated financial statements. Had
the Company determined compensation cost based on the fair value at the grant
date for its stock options under SFAS No. 123, the Company's net income would
have been adjusted to the pro forma amount indicated below:

</TABLE>

Pro forma net income reflects only options granted after January 1, 1995.
Therefore, the full impact of calculating compensation cost for stock options
under SFAS No. 123 is not reflected in the pro forma net income amounts
presented above because compensation cost is reflected over the options'
vesting period of five years and compensation cost for options granted prior to
January 1, 1995 is not considered.

(10) Stock Plans (continued)

Warrants are granted with an exercise price equal to or greater than the
stock's estimated fair market value at the date of grant, vest immediately and
may be exercised at any time until the expiration date.

(11) Employee Benefit Plans

The Company has two defined contribution 401(k) plans, which commenced in 1980
and 1988, covering a majority of its employees. These plans are designed to be
tax deferred in accordance with the provisions of Section 401(k) of the
Internal Revenue Code. Employees may contribute from 1% to 20% of compensation
on a tax-deferred basis through a "salary reduction" arrangement. In 1998, the
Company implemented a discretionary employer matching contribution program,
with a five-year vesting schedule, whereby the Company matches 50% of the first
1% of employee contributions for the year. No employer contributions were made
during 1996 and 1997. During 1998, the Company contributed $55,000 to its
401(k) plans, which represented the Company's entire obligation under the
employer matching contribution program for the year ended December 31, 1998.
Effective January 1, 1999, the Company increased the employer contribution
percentage to 50% of the first 6% of employee contributions, not to exceed
$1,500 per employee per year.

                   THE KEITH COMPANIES, INC. AND SUBSIDIARIES

            Notes to Consolidated Financial Statements--(Continued)
                Years Ended December 31, 1996, 1997 and 1998 and
             Three Months Ended March 31, 1998 and 1999 (Unaudited)


(12) Income Taxes (continued)

The net change in the valuation allowance for the years ended December 31,
1996, 1997 and 1998 was a decrease of $663,000 and $1,761,000, and an increase
of $31,000, respectively. The Company considers recording a valuation allowance
in accordance with the provisions of SFAS No. 109 to reflect the estimated
amount of deferred tax assets, which may not be realized. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not, that some portion or all of the deferred tax assets will not
be realized. The ultimate realization of deferred tax assets is dependent upon
the generation of future taxable income during the periods in which those
temporary differences become deductible. Management considers the scheduled
reversal of deferred tax liabilities, projected future taxable income and tax
planning strategies in making this assessment, and believes it is more likely
than not the Company will realize the benefits of its deferred tax assets, net
of the existing valuation allowance at December 31, 1998. The amount of the
deferred tax asset considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.

As of December 31, 1998, the Company had approximately $3,500,000 and
$1,400,000 in federal and state net operating loss carryforwards, respectively,
available to offset future taxable income, if any. The federal carryforwards
expire from the years 2007 to 2018. The state carryforwards expire from the
years 1999 to 2003.

(13) Commitments and Contingencies

The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management and the Company's
legal counsel, the ultimate disposition of these matters will not have a
material adverse effect on the Company's financial position, liquidity and
results of operations.

(14) Segment and Related Information

The Company evaluates performance and makes resource allocation decisions based
on the overall type of services provided to customers. For financial reporting
purposes, we have grouped our operations into two primary reportable segments.
The Real Estate Development, Public Works and Wireless Telecommunications
("REPWWT") segment includes engineering, consulting and technical services for
the development of both private projects, like residential communities,
commercial and industrial properties and recreational projects; public works
projects, like transportation and water/sewage facilities; and site acquisition
and construction management services for wireless telecommunications. The
Industrial Engineering ("IE") segment, which consists of ESI, provides the
technical expertise and management required to design and test manufacturing
facilities and processes. The accounting policies of the segments are the same
as those described in note 2.

(14) Segment and Related Information (continued)

Business Concentrations

In 1996 and 1998, the Company had no customers which represented greater than
10% of consolidated net revenue. In 1997, the Company had one customer which
represented 11% of net revenue. In addition, in 1997 the Company had one
customer representing greater than 10% of net contract and trade receivables.
Receivables from this customer totaled $1,283,000 at December 31, 1997. No
customers represented greater than 10% of net contract and trade receivables at
December 31, 1998.

(15) Fair Value of Financial Instruments

The carrying amounts of the Company's financial instruments reported in the
accompanying consolidated balance sheets for cash, contracts and trade
receivables, other receivables, short-term borrowings, trade accounts payable,
accrued employee compensation, accrued liabilities to related parties, and
other accrued liabilities approximate fair values due to the short maturity of
these instruments.

At December 31, 1998, long-term debt, excluding capital lease obligations,
consisted of the Company's line of credit payable, notes payable and notes
payable to related parties. The carrying value of the Company's line of credit
payable approximates its fair value, based upon the borrowing rate currently
available to the Company for loans with similar terms. It was not practicable
to estimate the fair value of two notes payable with a combined carrying value
of $576,000, as there is no established market for these notes. The carrying
value of the remaining long-term debt and notes payable to related parties was
$3,151,000, which approximates fair value, determined using estimates for
similar debt instruments (see notes 5 and 6).

(18) Extraordinary Gain

In 1990, the Company entered into a facility lease in Moreno Valley, California
anticipating growth in operations. By December 31, 1994, concurrent with the
recession in the southern California real estate industry, the Company's
operations from this location had diminished significantly resulting in
excessive lease space. Accordingly, the Company accrued a loss of $2,028,000,
based on its obligation for the excess space through the lease expiration date,
as the excess space had no substantive future use or benefit to the Company. In
addition, the Company was in default under the lease and had accrued unpaid
rent totaling $658,000 through December 31, 1995. During 1995, the landlord
issued a deed-in-lieu of foreclosure to the mortgage holder who subsequently
sold the building. The Company entered into an agreement with the new landlord
in August 1996, whereby all amounts owing under the previous lease through
December 31, 1995 were forgiven and a new lease was negotiated effective
January 1, 1996. Therefore, the Company recorded an extraordinary gain on the
forgiveness of $2,686,000 in 1996.

In connection with the original lease, a partnership owned by the two major
stockholders of TKCI, held a 25% ownership interest in the building and a small
interest in the overall project. As a result of the Company's default on the
lease, the partnership's ownership interest in the project was forfeited.

(19) Subsequent Event

Thompson-Hysell, Inc.

On April 9, 1999, TKCI entered into an Asset Purchase Agreement with Thompson-
Hysell, Inc. ("Thompson-Hysell") and its shareholders (the "Acquisition
Agreement"). Under the terms of the Acquisition Agreement, TKCI is to acquire
substantially all of the assets of and assume substantially all of the
liabilities of Thompson-Hysell. Based on the terms of the

(19) Subsequent Event (continued)

Acquisition Agreement, TKCI is obligated to initially pay cash in the amount of
$3,333,333. Contingent consideration consists of a promissory note to be issued
at closing in the original principal amount of $1,333,333, and shares of common
stock with a value equal to $1,333,334. In addition, TKCI may be obligated or
entitled to pay or receive cash related to financial targets and pay cash
related to the income tax effects to the sellers of Thompson-Hysell. The
issuance of common stock, the principal balance of the promissory note and the
payment of additional cash are contingent upon the net book value of assets
acquired and liabilities assumed compared to $1,000,000, earnings for the years
ended December 31, 1999 and 2000 and the income tax effect on the shareholders
of Thompson-Hysell. It is anticipated this transaction is to close concurrent
with the Company's planned initial public offering. As of March 31, 1999, the
Company has incurred approximately $104,000 (unaudited), consisting primarily
of legal and accounting costs, related to the acquisition of Thompson-Hysell.
These acquisition costs have been deferred and included in the March 31, 1999
accompanying consolidated balance sheet in other assets. Should the Company
decide not to consummate the Thompson-Hysell acquisition, these costs would
then be expensed.

                   Years Ended December 31, 1997 and 1998 and

(1) Organization and Summary of Significant Accounting Policies

Company's Activities and Operating Cycle

Thompson-Hysell, Inc. (the "Company") was incorporated as an S Corporation on
December 20, 1996 in California, with significant operations commencing on May
1, 1997. The Company provides civil engineering for private land development
and large development projects, and provides project planning and heavy
construction surveying/staking along with construction management, primarily in
central California and Utah. The work is performed under fixed price and time
and material contracts, some of which have not to exceed provisions. The length
of the Company's contracts varies but are typically from one to three years. In
accordance with normal practice in the civil engineering industry, the Company
includes asset and liability accounts relating to engineering contracts in
current assets and liabilities even when these amounts are realizable or
payable over a period in excess of one year.

Interim Financial Statements

The accompanying balance sheet as of March 31, 1999 and the statements of
income and cash flows for the three months ended March 31, 1998 and 1999, and
the statement of stockholders' equity for the three months ended March 31, 1999
are unaudited and have been prepared on the same basis as the audited financial
statements included herein. In the opinion of management, the unaudited
financial statements include all adjustments necessary to present fairly the
information set forth therein, which consist solely of normal recurring
adjustments. The results of operations for the interim periods are not
necessarily indicative of results for the full year.

Engineering Contract Income Recognition

For financial reporting purposes, profits on engineering contracts are recorded
using the percentage-of-completion method of accounting, determined by the
ratio of costs incurred to date to management's estimates of total anticipated
costs. These amounts necessarily are based on estimates, and the uncertainty
inherent in the estimates initially is reduced progressively as work on the
contract nears completion.

Costs of revenue include all direct material, labor, subcontractor costs and
those indirect costs related to contract performance, like indirect labor,
supplies, tools, equipment costs, and depreciation and amortization applicable
to autos and trucks under capital leases. Selling, general and administrative
costs are expensed as incurred. If estimated total costs for a

                   Notes to Financial Statements--(Continued)

                   Years Ended December 31, 1997 and 1998 and
             Three Months Ended March 31, 1998 and 1999 (Unaudited)

contract indicate a loss, the Company provides currently for the total
anticipated loss on the contract. Changes in job performance, job conditions,
and estimated profitability may result in revisions to revenue and costs, which
are recognized in the period in which the revisions are determined.

Costs and estimated earnings in excess of billings represents revenue
recognized in excess of amounts billed. Billings in excess of costs and
estimated earnings represents billings in excess of revenue recognized.

Cash and Cash Equivalents

For purposes of reporting cash flows, the Company considers all cash accounts
that are not subject to withdrawal restrictions or penalties with maturities at
date of purchase of three months or less, to be cash or cash equivalents.

Equipment and Improvements

Equipment and improvements are recorded at cost. Depreciation is provided on
the straight-line method over the estimated useful lives of the assets. Autos
and trucks held under capital leases (stated at the present value of the future
minimum lease payments) and leasehold improvements are amortized on the
straight-line method over the shorter of the lease term or the estimated useful
life of the asset. Expenditures for maintenance and repairs are charged against
income in the year in which they are incurred and betterments are capitalized.
When depreciable assets are sold or disposed of, the cost and accumulated
depreciation accounts are reduced by the applicable amounts, and any profit or
loss is credited or charged to income.

lives:

Depreciation expense for the years ended December 31, 1997 and 1998, totaled
$11,000 and $65,000, respectively. Amortization expense for autos and trucks
under capital leases for the years ended December 31, 1997 and 1998, totaled
$36,000 and $73,000, respectively.

Marketable Investment Securities

Marketable investment securities at December 31, 1997 and 1998 and March 31,
1999, consist of equity securities and mutual funds. The Company has classified
its investments as available-for-sale, and has recorded them at fair market
value with any unrealized gains or losses reflected as a component of
stockholders' equity.

Income Taxes

The Company, with the consent of its stockholders, elected, under the Internal
Revenue Code, to be an S Corporation effective December 20, 1996. Under the S
election, the Company's income or loss is passed on to the individual
stockholders for federal and state income tax purposes. Therefore, there is no
federal tax liability at the corporate level and thus, no provision for federal
income taxes has been included in these financial statements. However, a tax is
assessed on income apportioned to California equal to the greater of $800 or
1.5% of income apportioned to California for franchise tax purposes.

                   Notes to Financial Statements--(Continued)
                   Years Ended December 31, 1997 and 1998 and
             Three Months Ended March 31, 1998 and 1999 (Unaudited)


Fair Value of Financial Instruments

The carrying amount reported in the balance sheet of the assets and liabilities
that are considered to be financial instruments, like cash and cash
equivalents, accounts receivable, deposits, accounts payable, accrued
liabilities, dividends payable, related party payables and line of credit
payable. The amounts of which these items are reported approximate their fair
value based upon their short-term nature. The carrying amount of notes payable
approximates fair value since their terms and conditions are similar to those
currently available to the Company.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of revenue and expenses during the reporting period.
Accordingly, actual results could differ from those estimates.

(2) Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable is composed of amounts due from clients, which vary from
private individuals to large construction companies. Consequently, the
Company's ability to collect the amounts due is affected by fluctuations in the
economy of the local community. The Company provides an allowance for
uncollectible accounts based upon prior experience and management's assessment
of the collectibility of existing specific accounts.

(10) 401(k) Profit Sharing Plan

The Company provides a 401(k) Profit Sharing Plan to their employees. Employees
are eligible to participate immediately; however, the Company does not match
until after one full year of service. After one year, the Company matches 50%
of what each employee puts into the plan, up to 5% of their gross annual salary
subject to limitations imposed by the Internal Revenue Code. Matching
contributions to the plan for the years ended December 31, 1997 and 1998, were
$27,000 and $54,000, respectively.

(11) Business and Credit Concentrations

The Company's primary operations are located in central California, and the
Salt Lake City, Utah areas. Thus, the Company is susceptible to economic
conditions in those geographical areas.

The Company maintains its cash balances at Wells Fargo Bank. Combined accounts
at the institution are insured by the Federal Deposit Insurance Corporation up
to $100,000. At December 31, 1998 and March 31, 1999, the Company's uninsured
cash balances totaled $266,000 and $164,000, respectively.

(12) Purchase of Stock

The Company has a shareholder agreement for the purchase of a retiring
shareholder's stock in the Company. Included in the agreement is term life
insurance on some of the shareholders. By board action, it is understood that
when a shareholder's stock is purchased, the term life insurance will be
transferred to the shareholder.

(13) Subsequent Event

On April 9, 1999, the Company entered into an Asset Purchase Agreement with an
unrelated third party to sell substantially all of the assets and substantially
all of the liabilities of the Company for cash, a promissory note and common
stock of the Company with an aggregate value of $6,000,000. The purchase price
is subject to change based on financial criteria and achieving earnings goals.
The transaction is anticipated to be consummated concurrent with the unrelated
third party's initial public offering.
