                               PROSPECTUS SUMMARY
   
   This summary highlights information contained elsewhere in this prospectus.
Before investing in the common stock, you should read the entire prospectus
carefully, including the "Risk Factors" section and the financial statements
and the notes to those statements. The information in this prospectus,
including number of shares and share prices, has been adjusted to reflect the
conversion of each outstanding share of Class A preferred stock into one share
of common stock and a ten-for-one stock split of the common stock.     
 
General
 
   CH2M HILL provides engineering, consulting, design, construction,
procurement, operations, maintenance, and project management services to our
clients in the public and private sectors. We provide services to our domestic
and foreign clients through three operating segments:
 
  . Environmental, Energy and Infrastructure
 
  . Water
 
  . Industrial
 
   For the year ended December 31, 1998, CH2M HILL had gross revenues of
approximately $935 million.
 
   Environmental, Energy and Infrastructure consists of two businesses:
Environmental, Nuclear, Energy & Systems and Transportation. The Environmental,
Nuclear, Energy & Systems business provides integrated environmental and waste
management consulting and engineering services, and performs design and build,
remediation, construction and implementation of infrastructure and
telecommunications systems for a variety of public and private clients. The
Transportation business provides planning, siting, permitting, design, program
and construction management, transportation management and consulting services
for aviation, ports, highways, bridges and transit systems.
 
   Water consists of two businesses: Water & Wastewater and Operations &
Maintenance. The Water & Wastewater business focuses on the planning, design,
construction and implementation of water supply systems and wastewater
treatment facilities. The Operations & Maintenance business provides services
to water and wastewater operators, including startup, performance testing,
facility operations, maintenance and management.
 
   Industrial provides design, construction, specialized precision
manufacturing support and facility services to high-technology manufacturing
companies, food and beverage processing businesses and fine chemical and
pharmaceutical manufacturers.
 
Business Strategy
 
   CH2M HILL is seeking to grow through increasing market share in each of our
operating segments both domestically and internationally. The key elements of
our strategy include:
 
  . Increasing the number and the dollar value of our contracts
 
  . Expanding and diversifying our client base
 
  . Increasing the number of large, longer-term projects with the potential
    for higher profit margins
 
  . Encouraging ownership in our common stock across a greater proportion of
    our workforce
   
Expansion of Common Stock Ownership     
 
   Historically, our key employee policy has restricted ownership of common
stock to persons known as "key employees," and to employee benefit trusts.
Employees were selected for key employee status by existing key employees on
the basis of various objective and subjective criteria. To expand our ownership
base beyond "key employees," the Board of Directors decided to establish a new
ownership program as a replacement for the key employee policy. The main goals
of the new program are:
 
  . Establishing an internal market to enable shareholders to buy and sell
    common stock
 
                                       1
<PAGE>
 
 
  . Expanding the opportunity for common stock ownership to include all
    eligible employees, directors and consultants
 
  . Adopting new and amending existing employee benefit plans to encourage
    employees to invest in common stock
   
Operation of the Internal Market     
   
   Through the internal market, any eligible shareholder may offer shares of
common stock for sale to eligible buyers up to four times each year on pre-
determined trade dates. Our 401(k) plan, employee stock plan, stock option
plan, payroll deduction stock purchase plan and trusts holding common stock for
the benefit of the employees may also participate in these trades. Shares will
be bought and sold through the internal market at a price determined by the
Board of Directors that is intended to represent fair market value. The stock
price is determined by the Board of Directors based upon our after-tax profits,
otherwise referred to as net income, and shareholders' equity as well as a
subjective analysis of market factors the Board of Directors considers
relevant. CH2M HILL may purchase or sell shares of common stock on the internal
market on any trade date to balance the supply and demand for common stock
between sellers and buyers, but we will not be obligated to do so.

   Our principal executive offices are located at 6060 South Willow Drive,

                                  RISK FACTORS
   
    This prospectus contains forward-looking statements that involve risks and
uncertainties. Our actual results may differ significantly from the results
discussed in the forward-looking statements. You should carefully consider the
following factors and other information contained in this prospectus before
deciding to invest in our common stock.     
   
Government Contracts Present Risks of Termination for Convenience, Adjustment
of Payments Received, Restrictions on Ability to Compete for Government Work
and Funding Constraints     
   
    In 1998, we derived approximately 63% of our total revenues from contracts
with federal, state, local and foreign government agencies. In addition, we own
equity interests in joint ventures with revenues attributable primarily or
entirely to contracts with governmental clients. The following risks are
inherent in government contracts:     
   
  . Because federal law and some state laws permit government agencies to
    terminate a contract for convenience, our governmental clients may
    terminate or decide not to renew our contracts with little or no prior
    notice.     
   
  . Federal governmental clients may audit contract payments we receive for
    several years after these payments are made. Based on these audits, the
    clients may adjust or demand repayment of payments we previously
    received. Audits have been completed on our federal contracts through
    December 31, 1994 and are continuing for subsequent periods. None of the
    audits performed to date on our federal contracts have resulted in any
    significant adjustments to our financial statements. We believe, on the
    basis of the information that we currently have about the ongoing audits,
    that the ongoing audits will not result in material adjustments to our
    financial statements. However, we cannot be sure that an audit in the
    future will not result in a material adjustment to our financial
    statements.     
   
  . Federal government contract regulations provide that any company
    convicted of a crime or indicted on a violation of statutes related to
    federal contracting may lose its right to receive future contract awards
    or extensions. To our knowledge, we are not currently subject to any
    investigation that may affect our ability to compete for federal
    government work.     
   
  . Our ability to earn revenues from our existing and future government
    projects will depend upon the availability of funding from various
    federal, state, local and foreign government agencies and private sector
    clients. We cannot control whether those clients will fund or continue
    funding our outstanding projects.     
   
    Our ability to secure new government contracts and our revenues from
existing government contracts could be adversely affected by any one or a
combination of the factors listed above.     
   
We Could Sustain Losses on Our Fixed Price Contracts If Our Costs Exceed the
Fixed Price     
   
    Under "fixed price" contracts, we estimate the costs of the project and
agree to deliver the project for a definite, predetermined payment regardless
of our actual costs incurred over the life of the project. Many fixed price
contracts involve large industrial facilities and public infrastructure
projects and present the risk that our costs to complete a project may exceed
the fixed price agreed to with the client. The fixed payments negotiated for
such projects may not cover our actual costs and desired profit margins for
such projects. If our actual costs for a fixed price project are higher than we
expect, our profit margins on the project will be reduced or we could suffer a
loss on the affected project.     
 
                                       3
<PAGE>
 
   
A Reduction in the Scope of Environmental Regulations or Changes in Government
Policies Could Adversely Affect Our Revenues     
   
    A substantial portion of our business is generated either directly or
indirectly as a result of federal, state, local and foreign laws and
regulations related to environmental matters. Changes in environmental
regulations could affect our business more significantly than they would affect
some other engineering firms. Accordingly, a reduction in the number or scope
of these laws and regulations, or changes in government policies regarding the
funding, implementation or enforcement of such laws and regulations, could
significantly reduce the size of one of our most important markets and limit
our opportunities for growth or reduce our revenues below their current levels.
In addition, any significant effort by government agencies to reduce the role
of private contractors in regulatory programs, including environmental
compliance projects, could have the same adverse effects.     
   
Our Environmental Remediation Work May Expose Us to Environmental Liability
       
    We could become subject to liabilities or fines for our environmental
activities. The assessment, analysis, remediation, handling, management, and
disposal of hazardous substances compose a significant portion of our business
and involve significant risks, including the possibility of property damages,
personal injuries, fines and penalties and other regulatory action. Civil and
criminal liabilities and liabilities to clients and third parties for
environmental violations and damages can be very large. Although we have never
been subject to any significant fines relating to environmental matters, it is
possible that we could be subject to substantial fines or liabilities in the
future. In that case, the fines could reduce our net income, or cause a loss,
and other penalties could adversely affect our ability to compete for new
business in the future.     
   
Our Projects May Result in Liability for Faulty Engineering Services     
   
    Because our projects are often large and can affect many people, our
failure to make judgments
    
          
and recommendations in accordance with applicable professional standards could
result in disproportionately large damages and, perhaps, punitive damages. Our
engineering practices involve professional judgments regarding the planning,
design, development, construction, operation and management of industrial
facilities and public infrastructure projects. Although we have adopted a range
of insurance, risk management and avoidance programs designed to reduce
potential liabilities, there can be no assurance that such programs will
protect us fully from all risks and liabilities.     
   
Absence of a Public Market May Prevent You from Selling Your Stock and Cause
You to Lose All or Part of Your Investment     
   
    There is no public market for our common stock. While we intend the
internal market to provide liquidity to shareholders, there can be no assurance
that there will be enough orders to purchase shares to permit shareholders to
resell their shares on the internal market, or that a regular trading market
will develop or be sustained in the future. The price in effect on any trade
date may not be attractive enough to both buyers and sellers to result in a
balanced market because the price will be fixed in advance by the Board of
Directors, using their judgment of the fair market value of the common stock,
and not by actual market trading activity. Moreover, although CH2M HILL may
enter the internal market as a buyer of common stock if there are more sell
orders than buy orders, we have no obligation to engage in internal market
transactions and will not guarantee market liquidity. Consequently,
insufficient buyer demand could cause sell orders to be prorated, or could
prevent the internal market from opening on any particular trade date.
Insufficient buyer demand could cause shareholders to suffer a total loss of
investment or substantial delay in their ability to sell their common stock. No
assurance can be given that shareholders desiring to sell all or a portion of
their shares of common stock will be able to do so. Accordingly, the purchase
of common stock is suitable for you only if you have limited need for liquidity
in this investment.     
 
                                       4
<PAGE>
 
   
Investors in the Offering Will Experience Immediate and Substantial Dilution
    
   
    The initial offering price per share of common stock exceeds CH2M HILL's
net tangible book value per share. Accordingly, the purchasers of shares sold
in the offering will experience immediate and substantial dilution. At the
stock price in effect for 1999 of $4.31 per share, based on our net tangible
book value per share of $2.60 as of December 31, 1998, new investors will
experience immediate dilution of $1.52 per share, or 35.3%.     
   
Transfer Restrictions on the Common Stock Could Prevent You from Selling Your
Stock and Cause You to Lose All or Part of Your Investment     
   
    The transfer restrictions applicable to the common stock could cause you to
lose all or part of your investment. Since all of the shares of common stock
will be subject to transfer restrictions, you will generally only be able to
sell your stock on one of the four trade dates for the internal market in each
year. Unlike shares that are actively traded in the public markets, you may not
be able to sell at a particular time even though you would like to. The stock
price could decline between the time you want to sell and the time you become
able to sell.     
   
The Offering Price Is Determined by the Board of Directors' Judgment of Fair
Market Value and Not by Market Trading Activity     
   
    The offering price is, and subsequent offering prices at each trade date
will be, established by the Board of Directors, taking into consideration the
valuation formula and several other factors which are described in the section
of this other prospectus called "Internal Market Information." Our Board of
Directors intends the formula to result in offering prices for the common stock
that represent fair market value. The formula is subject to change at the
discretion of the Board of Directors.

transferability.     
                          INTERNAL MARKET INFORMATION
       
General
   
    This section contains a summary of the material provisions of:     
 
  . Our key employee policy
 
  . The transition from the key employee policy to the internal market
 
  . How the internal market will work
   
We encourage you to read the entire key employee policy and the internal market
rules, which are attached as exhibits to the registration statement filed with
the Securities and Exchange Commission.     
   
    Until this offering, our principal policy on stock ownership has been our
key employee policy, which restricted ownership of the common stock to persons
referred to as "key employees." As of May 1999, approximately 1,000 key
employees held common stock. To expand our ownership base beyond key employees,
the Board of Directors decided to establish a new ownership program as a
replacement for the key employee policy. The main goals of the new program are:
    
  . Establishing an internal market to enable shareholders to buy and sell
    common stock
 
  . Expanding the opportunity for common stock ownership to include all
    eligible employees, directors and consultants
 
  . Adopting new and amending existing employee benefit plans to encourage
    employees to invest in common stock

Our Existing Shareholders Received Common Stock Under Key Employee Policy     
   
    Under the key employee policy, existing key employees voted to select new
key employees recommended by the Board of Directors. To earn the recommendation
of the Board of Directors to become a key employee, an employee generally had
to work for CH2M HILL for four or more years, receive consistent high job
performance evaluations and be deemed critical to the success of CH2M HILL.
Designation as a key employee qualified an individual to receive bonuses in the
form of stock and cash. Each year we granted bonuses expressed in dollar
amounts, but paid in shares of common stock and cash, to selected key employees
based on job performance and position. Upon a key employee's termination or
retirement, we repurchased his or her shares at a price calculated according to
a formula established annually by the Board of Directors.     
 
    Under the old formula, the market value of a share of common stock was
equal to the sum of present book value ("PBV") and the present going concern
value ("PGCV") divided by the number of outstanding shares of stock ("CS").
 
                      Old Formula Price = (PBV + PGCV)/CS
 
    "PBV" was the total audited book value of CH2M HILL at the end of the most
recent fiscal year, prior to giving effect to the issuance of bonuses for the
most recent fiscal year. Nonrecurring or unusual transactions could be excluded
from the calculation at the discretion of the Board of Directors.
 
    "PGCV" was 1.5 times the previous five fiscal year rolling average of net
income. Net income was defined as the net income on an accrual basis according
to our audited financial statements, after the deduction of all costs but
before the deduction of bonuses and income taxes. Nonrecurring or unusual
transactions could be excluded from the calculation at the discretion of the
Board of Directors.
   
    As of May 1, 1999, approximately 1,000 key employees and the employee
benefit plan trusts held 29,400,380 shares of common stock.

Transition from the Key Employee Policy to the Internal Market     
   
    In connection with establishing a new ownership program, on November 6,
1998, the Board of Directors terminated the key employee policy and established
the internal market, effective on the date that the contingencies described
below are satisfied, and adopted the 1999 Stock Option Plan. Our shareholders
approved these actions of the Board of Directors during the key employee vote
on December 18, 1998. The Board of Directors will approve the final terms of
all of the other benefit plans before any common stock is sold under this
prospectus.     
   
    These actions by the Board of Directors, however, remain subject to the
effectiveness of the registration statement and to the rules and regulations of
the Securities and Exchange Commission and the securities commissions of a
sufficient number of states so that the internal market can function
efficiently, as determined by the Board of Directors in its discretion. The
Board of Directors intends to review the status of these contingencies at its
November 1999 meeting and determine at that time whether to proceed with the
internal market offering. Once these contingencies have been satisfied, the old
formula will no longer be in effect and the key employee policy will not govern
new transactions in the common stock. The conversion of the Class A preferred
stock and the ten-for-one split of the common stock would then be given effect
prior to the first trade date.

How the Internal Market Works     
 
    The internal market will permit shareholders, eligible employees and the
benefit plans to buy and sell shares of common stock up to four times each year
on predetermined trade dates.
   
    Authorized Buyers. All sales of common stock on the internal market will be
restricted to the following authorized buyers:     

                              [CHART APPEARS HERE]
 
Limitations on the number of shares which an individual may purchase may be
imposed when there are more buy orders than sell orders for a particular trade
date.
   
    Broker. We established and will manage the internal market through a
broker, initially Buck Investment Services, Inc., which will act upon
instructions from the buyers and sellers. Buck Investment Services, Inc. is not
affiliated with CH2M HILL. Individual stock ownership account records will be
maintained by the broker. Subsequent to determination of the applicable stock
price for use on the next trade date, and at approximately fifteen days prior
to such trade date, we will advise all employees and directors as to the new
stock price and the next trade date, inquiring whether such individuals wish to
purchase or sell shares on the internal market and advising them on how to
deliver written buy and sell orders approximately five days prior to such trade
date.     
   
    CH2M HILL May Purchase Shares if Market is Under-Subscribed. CH2M HILL may,
but is not obligated to, purchase shares of common stock on the internal market
on any trade date, but only to the extent that the number of shares offered for
sale by shareholders exceeds the number of shares sought to be purchased by
Authorized Buyers.     
 
    If the aggregate number of shares offered for sale on the internal market
on any trade date is greater than the number of shares sought to be purchased,
shareholder offers to sell will be accepted as follows:
 
  . If enough orders to buy are received to purchase all the shares offered
    by each seller selling fewer than 500 shares and at least 500 shares from
    each other seller, then all sell orders will be accepted up to the first
    500 shares and the portion of any sell orders exceeding 500 shares will
    be accepted on a pro-rata basis.
 
  . If not enough orders to buy are received to purchase all the shares
    offered by each seller selling fewer than 500 shares and at least 500
    shares from each other seller, then the purchase orders will be allocated
    equally to each seller.
   
    CH2M HILL May Sell Shares if Market is Over-Subscribed. To the extent that
the aggregate number of shares sought to be purchased exceeds the aggregate
number of shares offered for sale, CH2M HILL may, but is not obligated to, sell
authorized but unissued shares of common stock on the internal market to
satisfy purchase demands.     
 
    If the aggregate purchase orders exceed the number of shares available for
sale, the following prospective purchasers will have priority, in the order
listed:
 
  . Administrator of the Payroll Deduction Stock Purchase Plan
 
  . Trustees of the 401(k) Plan
 
  . Trustees of the Employee Stock Plan
   
  . Individual employees and directors on a pro rata basis which includes
    purchases through the pre-tax and after-tax deferred compensation plans
        
                                       8

<PAGE>
 
   
    Sellers Pay Sales Commission. All sellers on the internal market, other
than CH2M HILL and the employee benefit plans, will pay the broker, initially
Buck Investment Services, Inc., a commission equal to 2% of the proceeds from
such sales. No commission is paid by Authorized Buyers on the internal market.
All offers and sales of common stock made on the internal market may be
attributed to CH2M HILL for securities law purposes.     
 
    Stock Price Determined by Board of Directors. The Board of Directors will
determine the price, which is intended to be the fair market value, of the
shares of common stock on each trade date pursuant to the formula and valuation
process described below. The formula price per share of common stock is as
follows:
 
                              [CHART APPEARS HERE]
 
    "M" is the market factor, which is subjectively determined in the sole
discretion of the Board of Directors. In determining the market factor, the
Board of Directors will take into account factors the directors consider to be
relevant in determining the fair market value of the common stock, including:
   
  . the market for publicly traded equity securities of companies comparable
    to CH2M HILL     
   
  . the merger and acquisition market for companies comparable to CH2M HILL
        
  . the prospects for CH2M HILL's future performance
 
  . general economic conditions
 
  . general capital market conditions
 
  . other factors the Board of Directors deems appropriate
   
    The Board of Directors may take into account the company appraisal
information obtained by the trustees of the benefit plans. The Board has not
assigned predetermined weights to the various factors it may consider in
determining the market factor. A market factor greater than one would increase
the formula price and a market factor less than one would decrease the formula
price.     
   
    In its discretion, the Board of Directors may change, from time to time,
the market factor component of the formula price. The Board of Directors could
change the market factor, for example, following a change in general market
conditions that either increased or decreased stock market equity values
generally, if the Board of Directors felt that the market change were
appropriately applicable to the common stock as well. The Board of Directors
will not make any other change in the method of determining the formula price
unless in the good faith exercise of its fiduciary duties and after
consultation with its professional advisors, the Board of Directors determines
that the formula price no longer results in a stock price that reasonably
reflects the fair market value of CH2M HILL on a per share basis.     
   
    "P" is profit after tax, otherwise referred to as net income, for the four
fiscal quarters immediately preceding the trade date. Nonrecurring or unusual
transactions could be excluded from the calculation at the discretion of the
Board of Directors.     
   
    "SE" is total shareholders' equity, which includes intangible items, as set
forth on CH2M HILL's most recently available quarterly or annual financial
statements. Nonrecurring or unusual transactions could be excluded from the
calculation at the discretion of the Board of Directors.     
   
    "CS" is the number of shares of common stock outstanding at the end of the
fiscal quarter immediately preceding the trade date on a fully diluted basis.
By "fully diluted" we mean that the calculations are made as if all outstanding
options to purchase common stock had been exercised and as if other "dilutive"
securities were converted into shares of common stock.     
   
    Under the new formula, and as demonstrated by the following calculation,
the formula price would have been $4.30 per share based on a market factor of
1.0 on January 1, 1999. As of December 31, 1998, we had cumulative profit after
tax (P) of $5,812,000 and total shareholders' equity of $75,132,000.     
   
[(7.8X1.0X$5,812,000)+($75,132,000)]
                    
 ------------------------------
                               =$4.30     
        28,025,490
 
 
                                       9
<PAGE>
 
   
Under the old formula, the price for the common stock for 1999 is $4.31, as
determined by our Board of Directors.     
   
   Following a determination by our Board of Directors at their November, 1999
meeting to put the internal market into effect, commencing in the first quarter
of 2000, the stock price will be reviewed by the Board of Directors up to four
times each year.     
   
This review will be made in conjunction with Board of Directors meetings,
currently scheduled for February, May, August and November. The Board of
Directors believes that the valuation process described above will result in a
stock price that will reasonably reflect the fair market value of CH2M HILL on
a per share basis.     
                              [CHART APPEARS HERE]
   
    We intend to publish the current stock price and upcoming trade date prior
to each trade date to all participants in the internal market through internal
communications, including bulletins, electronic mail communications or mailed
reports. Trade dates are expected to occur approximately 75 days after the end
of each fiscal quarter.     
 
    We will also distribute our audited annual financial statements to all
shareholders, as well as other employees, and to participants in the internal
market through the employee benefit plans. Such information will be distributed
at the same time as our annual reports, proxy information and solicitations are
distributed for voting instructions from shareholders and participants in the
employee benefit plans each year.
 
Price Range of Common Stock
 
    Because the common stock has not been publicly traded, there has not been
any historical market-determined price. However, the Board of Directors has
periodically determined the price of the common stock for purposes of awards of
common stock made pursuant to the key employee policy.
   
    The price per share figures shown below for 1989 through 1999 are the stock
prices established by the Board of Directors pursuant to the old formula for
purposes of transactions under the key employee policy and employee benefit
plans. There can be no assurance that the common stock will, in the future,
provide returns comparable to historical returns.     
   
    The stock prices have been adjusted to reflect the ten-for-one stock split
that will be implemented in conjunction with the implementation of the internal
market.     
   
    Because of the change from the old formula to the new formula for
determining the price, the historical prices for the common stock are not
directly comparable to the stock prices that will be determined under the new
formula. Since the determination of the price includes market analyses that are
applied by the Board at the time of making its determinations, we do not know
what the historical prices for the common stock would have been under the new
formula.

                                USE OF PROCEEDS
   
    The shares of common stock which may be offered by CH2M HILL are
principally being offered to permit the acquisition of shares by the employee
benefit plans as described herein and to permit CH2M HILL to offer shares of
common stock on the internal market if necessary because there are more buy
orders than sell orders on a trade date. We do not intend or expect this
offering to raise significant capital. Any net proceeds received by CH2M HILL
from the sale of the common stock offered, after paying expenses of the
offering, will be added to our general funds and used for working capital and
general corporate purposes. It is anticipated that the majority of the sales of
common stock on the internal market will be made by shareholders and the
employee benefit plans. All shareholders other than CH2M HILL and the employee
benefit plans will pay a commission equal to 2% of the proceeds of the sale of
any shares of common stock. The commission will be used by the broker to defray
the costs of establishing and maintaining the internal market.     

                                DIVIDEND POLICY
 
    We do not currently anticipate paying any cash dividends on the common
stock and intend to retain any future earnings to finance the growth and
development of our business.
                                    DILUTION
 
    The tangible book value of CH2M HILL on December 31, 1998 was $72,946,000
or $2.60 per share. Tangible book value per share represents the amount of
total tangible assets less total liabilities, divided by the shares of common
stock then outstanding. Total common stock outstanding at December 31, 1998 was
28,025,940 shares. As the following table demonstrates, after giving effect to
the sale of 4,000,000 shares of common stock by CH2M HILL in the offering at a
formula price of $4.31 per share, and after deducting anticipated expenses that
had not been paid as of December 31, 1998, the pro forma book value of the
common stock on December 31, 1998 would have been $89,363,921 or $2.79 per
share, representing an immediate dilution of $1.52 per share to new investors
purchasing shares of common stock at the formula price. "Dilution per share"
represents the difference between the price per share to be paid by new
investors for shares issued in this offering and the net pro forma book value
per share as of December 31, 1998.

                                    BUSINESS
                                    Overview
 
    CH2M HILL is a project delivery firm founded in 1946. We provide
engineering, consulting, design, construction, procurement, operations and
maintenance, and program and project management services to clients in the
private and public sector in the United States and abroad.
 
    We are an employee-owned Oregon corporation with approximately 7,000
employees working in 65 offices throughout the United States and 33 offices
abroad.
 
                               Business Strategy
 
    Our business strategy is to grow domestically and internationally through
increasing market share in each of our operating segments. The key elements of
this strategy are:
 
  . Increasing the number and the dollar value of our contracts
 
  . Expanding and diversifying our client base by attracting new private and
    public sector clients and developing a diversified mix of projects
 
  . Increasing the number of large, longer-term projects with the potential
    for higher profit margins
 
  . Encouraging ownership in our common stock across a greater proportion of
    our workforce
 
                               Operating Segments
 
    We provide services to our clients through three operating segments:
 
  . Environmental, Energy and Infrastructure
 
  . Water
 
  . Industrial
 
Environmental, Energy and Infrastructure
 
    Our Environmental, Energy and Infrastructure ("EE&I") operating segment
consists of two businesses: Environmental, Nuclear, Energy & Systems ("ENE&S")
and Transportation. These two businesses are described below.
   
    EE&I's business strategy is to grow by increasing market share in each of
its two businesses, expanding its client base and obtaining large, longer-term
projects with the potential for higher profit margins. While maintaining its
focus on its traditional services, EE&I is expanding its expertise into related
industries such as telecommunications, and into related business concepts such
as "sustainable development." Sustainable development is a design approach
used, for example, in power plant design. Sustainable development addresses
environmental issues throughout the life of a project, from design and
construction to decommissioning. Sustainable development seeks to minimize
total environmental impact.     
 
    ENE&S. ENE&S provides integrated environmental and waste management
consulting and engineering services, and performs design and build,
remediation, construction and implementation of infrastructure and
telecommunications systems for a variety of public and private clients.
 
    1. Environmental. Our Environmental group provides environmental consulting
for remedial construction projects, ecological and natural resource damage
assessments, strategic environmental management and permitting services,
environmental liability management services, site investigations, remedial
design, implementation and construction services, treatment systems for
hazardous, toxic and radioactive waste contaminated properties, and sustainable
development planning, design and construction services.
 
    Representative Environmental projects include:
 
  . Environmental consulting, engineering and remedial activities for the
    U.S. Air Force Center for Environmental Excellence
 
  . Remediation of contaminated sites on Naval and Marine Corps
    installations in 26 domestic states and several foreign countries
 
  . Program management and remedial design of a refinery for a large oil
    company

 
                                       14
<PAGE>
 
  . Environmental impact studies for a number of proposed industrial projects
    and municipal programs on behalf of the Beijing city government in China
 
   2. Nuclear. Our Nuclear group provides program management, integration,
engineering, construction and operations and maintenance services for the U.S.
Department of Energy and commercial nuclear power plants. We manage
decommissioning and closure of weapons production facilities and design nuclear
waste treatment and handling facilities in the United States, Western, Central
and Eastern Europe and the former Soviet Union.
 
   Representative Nuclear projects include:
 
  . Management and integration of decontamination, decommissioning, and
    closure of the nuclear weapons production facility at Rocky Flats in
    Golden, Colorado, on behalf of the U.S. Department of Energy
 
  . Engineering, design and technical services to support decontamination,
    decommissioning and remedial activities at the Department of Energy
    Hanford Reservation in Richland, Washington
   
   3. Energy. Our Energy group provides full lifecycle energy services for

                                  Kaiser-Hill
 
    In 1995, through Kaiser-Hill Company, LLC ("Kaiser-Hill"), we won the U.S.
Department of Energy's Performance Based Integrating Management Contract for
the Rocky Flats Closure Project in Golden, Colorado. Kaiser-Hill is a joint
venture with ICF Kaiser International, Inc. in which we hold a 50 percent
interest. Rocky Flats is a former U.S. Department of Energy nuclear weapons
production facility. Under the five-year contract, Kaiser-Hill oversees
plutonium stabilization and storage, environmental restoration, waste
management, decontamination and decommissioning, site safety and security, and
construction activities of subcontractor companies.
 
    Under the performance-based contract signed by Kaiser-Hill, a concept that
was developed in the U.S. Department of Energy's 1994 Contract Reform
Initiative, 85% of Kaiser-Hill's fees are based on performance, while only 15%
are fixed. Kaiser-Hill's contract commits it to dealing with urgent risks
first. Achievement of measurable results in the following "urgent risk" areas
determines Kaiser-Hill's incentive fee: stabilize plutonium and plutonium
residues for specific time frames; consolidate plutonium in a single building;
and clean up and remove all high-risk "hot spot" contamination. The Rocky Flats
contract is scheduled to expire in June 2000. Kaiser-Hill is in the process of
applying for renewal of the contract, but there can be no assurance that the
contract will be renewed.
 
                                    Backlog
   
    At December 31, 1998, our backlog was approximately $1,337 million,
compared to a backlog of approximately $966 million at December 31, 1997. We
define backlog as contracted task orders less previously recognized revenue on
such task orders. U.S. government agencies operate under annual fiscal
appropriations by Congress and fund various federal contracts only on an
incremental basis. The same is true of many state, local and foreign contracts.
Our ability to earn revenues from our backlog depends on the availability of
funding for various U.S., state, local and foreign government agencies.     
 
                             Government Contracting
 
    Overall, we received 16% of our revenues in 1998 from U.S. federal
government contracts. Typically, a federal contract has an initial term of one
year combined with two, three, or four one-year renewal periods, exercisable at
the discretion of the federal government. The government is not obligated to
exercise its option to renew a federal contract. At the expiration of the term
of a federal contract, the contract in its entirety is resubmitted for
competitive bids by all interested service providers. The government's failure
to renew, or the early termination of, any significant portion of our federal
contracts would adversely affect our business and prospects.
   
    Contracts with the federal government and its prime contractors usually
contain standard provisions for termination at the convenience of the
government or such prime contractors. Upon such a termination, we are generally
entitled to recover costs incurred, settlement expenses and profit on work
completed prior to termination. Our federal contracts do not provide for
renegotiation of profits. Terminations of federal contracts may occur, and such
terminations could adversely affect our business and prospects.     
                                       17
<PAGE>
 
    Federal contract payments we receive in excess of allowable direct and
indirect costs are subject to adjustment and repayment after audit by
government auditors. The U.S. government has completed audits on our incurred
contract costs through December 31, 1994, and audits are continuing for
subsequent periods.
   
    As a U.S. government contractor, we are subject to federal regulations
under which our right to receive future awards of new federal contracts, or
extensions of existing federal contracts, may be unilaterally suspended or
barred if CH2M HILL is convicted of a crime or indicted based on allegations of
a violation of specific federal statutes. Suspensions, even if temporary, can
result in the loss of valuable contract awards for which we would otherwise be
eligible. While suspension and debarment actions may be limited to that
division or subsidiary of a company engaged in the improper activity,
government agencies have authority to impose debarment and suspension on
affiliated entities that were not involved in the improper activity. Any
suspension or debarment action against us or any of our affiliates could have a
material adverse impact upon our business and prospects.     
 
    Many similar regulations are also applicable to our contracts with state,
local and foreign governments.
             
          Our Environmental Activities and Potential Liabilities     
 
    A substantial portion of our business has been generated either directly or
indirectly as a result of federal, state, local and foreign laws and programs
related to protection of the environment. Our environmental activities are
conducted in the context of a rapidly developing and changing statutory and
regulatory framework. Such activities are subject to regulation by a number of
federal agencies, including the U.S. Environmental Protection Agency ("EPA"),
the U.S. Nuclear Regulatory Commission and the U.S. Occupational Safety and
Health Administration, as well as similar state, local and foreign regulatory
agencies.
   
    Several federal statutes govern our environmental activities. The
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")
established the "superfund" program to clean up hazardous waste sites, and
provides for penalties and punitive damages for noncompliance with EPA orders.
CERCLA may impose strict liability (joint and several as well as individual) on
hazardous substance waste owners, operators, disposal arrangers, transporters
and disposal facility owners and operators (collectively, "Potentially
Responsible Parties" or "PRPs"). Liabilities under CERCLA may include payment
of the costs of removal or remedial action, for other necessary response costs,
for damages for injury, destruction or loss of natural resources, and for the
cost of health effects studies.     
 
    Although the liabilities imposed by environmental legislation are generally
intended to remedy and prohibit pollution by industrial companies, we could
face liability under environmental laws in some circumstances. Increasingly,
there are efforts to expand the reach of CERCLA to make environmental
contractors responsible for cleanup costs by claiming that environmental
contractors are owners or operators of hazardous waste facilities or that they
arranged for treatment, transportation, or disposal of hazardous substances.
Should we be held responsible under CERCLA for damages caused while performing
services or otherwise, CH2M HILL could be forced to bear such liability by
itself, if contribution or indemnification is not available from other parties.
 
    The Resources Conservation and Recovery Act ("RCRA") governs hazardous
waste generation, treatment, transportation, storage, and disposal. RCRA, or
similar EPA-approved state programs, govern waste-handling activities involving
wastes classified as "hazardous." Substantial fees and penalties may be imposed
under RCRA and similar state statutes for any violation.
 
    In addition to civil and criminal liabilities under environmental laws, we
could face liabilities to clients and other private parties for property
damage, personal injury and other claims. Such claims could arise in a number
of ways, including:
 
  . An accidental release of pollutants during our performance of services
                                       18
<PAGE>
 
  . The inability of one of our remedial plans to contain or correct an
    ongoing seepage or release of pollutants
 
  . The inadvertent exacerbation by us of an existing contamination problem
 
  . Reliance by others on reports or recommendations we prepare that turn
    out to be incorrect
 
   In the environmental field, personal injury claims may arise in connection
with our work while it is being done or long after completion of the project.
In addition, claimants may assert that we should be strictly liable for
performing environmental remediation services -- that is, liable for damages
even though our services may have been performed using reasonable care -- on
the grounds that such services involve "abnormally dangerous activities."
             
          Our Contractual Obligations and Potential Liabilities     
   
   We operate under a number of different types of contracts with our private
and public sector clients, including cost reimbursement contracts, time-and-
materials contracts, and fixed price contracts. The most common type is the
fixed price contract, which accounted for 36.1% of our revenues in 1998. Under
fixed price contracts, we are paid a predetermined amount for all services
provided as determined at the project's inception. Under time-and-materials
contracts, we are paid at a specified fixed hourly rate for direct labor hours
worked. Under cost reimbursement contracts, our costs are reimbursed, often
with a negotiated cost ceiling and also with an incentive fee to provide
inducement for effective project management. We assume the greatest financial
risk on fixed price contracts because we assume the risk of performing those
contracts at the stipulated prices regardless of actual costs incurred. We
also incur some financial risks under time-and-materials contracts because we
contract to complete the work at negotiated hourly rates. The failure to
accurately estimate ultimate costs or to control costs during performance of
the work could result in losses or reduced anticipated profits.     
   
   When we perform services for our clients, we can become liable for breach
of contract, personal injury, property damage, and negligence. Such claims
could include improper or negligent performance or design, failure to meet
specifications, and breaches of express or implied warranties. Because our
projects are typically large enough to affect the lives of many people, the
damages available to a client or third parties are potentially large and could
include punitive and consequential damages. For example, our transportation
projects and manufacturing facility projects involve services and products
that affect not only our client, but also the many end users of those services
and products. In addition, our clients often require us to be responsible for
liabilities through contractual indemnities. Such provisions typically require
us to assume liabilities for damage or personal injury to the client, third
parties and their property, and also for fines and penalties.     
 
   We seek to protect CH2M HILL from potential liabilities by obtaining
indemnification where possible from our private sector clients. Under most of
our private sector contracts, we have been successful in obtaining such
indemnification, but such indemnification generally is not available if we
fail to satisfy specified standards of care in performing our services or if
the indemnifying party has insufficient assets to cover the liability.
   
   We also try to obtain available indemnities from our public sector clients.
For example, some of our clients, including some U.S. government agencies, are
Potentially Responsible Parties under CERCLA. Under our contracts with these
clients, we usually try to seek contribution from the client for liability
imposed on us in connection with our work at these clients' CERCLA sites. In
addition, when we perform superfund related work for our U.S. government
clients, CERCLA generally permits us to limit our potential liabilities.
However, the EPA recently has significantly narrowed the circumstances under
which it will indemnify contractors against liabilities incurred in connection
with CERCLA projects. There are also proposals both in Congress and at various
regulatory agencies to further restrict indemnification of contractors from
third-party claims. In connection with services at the Rocky Flats closure
project, Kaiser-Hill is indemnified by its U.S. government client against
liability claims

arising out of contractual activities involving a nuclear incident.
              
           International Operations Pose Risks and Complexities     
 
    We routinely conduct operations outside of the United States. Overall, we
derived approximately $57 million or 6.1% of our service revenues in 1998 from
such operations. International operations entail additional business risks and
complexities such as foreign currency exchange fluctuations, different taxation
methods, restrictions on financial and business practices and political
instability. Our international clients include both private sector firms and
foreign government agencies in more than 20 countries, with significant
projects in Egypt, Spain, Singapore, and New Zealand.
                       
                    Our Industry Is Highly Competitive     
   
    The market for the design, consulting, engineering and construction
services that we offer is highly competitive. We compete with many other
design, consulting, engineering and construction firms, including large
multinational firms having substantially greater financial, management, and
marketing resources. Other competitors are small firms with lower cost
structures enabling them to offer lower prices for particular services. We also
compete with government agencies, including our own clients, that can utilize
their internal resources to perform services that we might otherwise perform.
       
    Most contracts between public sector clients and our EE&I and Industrial
operating segment are awarded through a competitive bidding process that places
no limit on the number or type of potential service providers. The process
usually begins with a government agency request for proposal that delineates
the size and scope of the proposed contract. The government agency evaluates
the proposals on the basis of technical merit and cost. For the Water operating
segment, most contracts are awarded through qualification selection processes
that vary among projects.     
 
    In both the private and public sectors, acting either as a prime contractor
or as a subcontractor, we may join with other firms that we otherwise compete
with to form a team to compete for a single contract. Because a team can often
offer stronger combined qualifications than any firm standing alone, these
teaming arrangements can be very important to the success of a particular
contract competition or proposal. Consequently, we maintain a network of
relationships with other companies to form teams that compete for particular
contracts and projects.
                  
               Conflicts of Interest May Limit Opportunities     
   
    Many of our clients and potential clients are concerned about actual or
possible conflicts of interest in retaining professional services consultants.
Governmental agencies and some private sector clients have contracting policies
that may, from time to time, prevent us from seeking or performing contracts
for other clients if there is a conflict of interest. We have, on occasion,
declined to bid on particular projects because of actual or perceived conflicts
of interest, and we are likely to continue encountering such conflicts of
interest in the future.     
                            
                         Our Properties are Leased     
 
    Our corporate headquarters, a 131,000 square foot facility, is located at
6060 South Willow Drive, Greenwood Village, Colorado 80111. We lease all of our
significant facilities, including our corporate headquarters and 65 domestic
and 33 foreign office locations, under many separate leases. We believe that
comparable facilities are available for lease and therefore that the loss of
any such leases would not have a material adverse impact on our operations. We
believe that our facilities are adequate for the present needs of our business.
                  
               We Are Not Involved in any Material Lawsuits     
   
    CH2M HILL is party to various legal actions arising in the normal course of
its business, some of which involve claims of substantial sums. Damages
assessed in connection with and the cost of defending any such actions could be
substantial. CH2M HILL's management believes that the levels of insurance
coverage are generally adequate to cover CH2M HILL's liabilities, if any, with
regard to such claims. CH2M HILL generally accrues amounts for retentions and
deductibles based on advice from legal counsel when it is probable that a loss
will be incurred and such loss is estimable. Gain contingencies or recoveries
are rare and are usually recorded when the cash is collected.

                                  Introduction
 
    The engineering and construction industry has been undergoing substantial
change as public and private clients privatize and outsource many of the
services that were formerly provided internally. Numerous mergers and
acquisitions in the industry have resulted in a group of larger firms that
offer a full complement of single-source services including studies, designs,
construction, operations, and in some instances, facility ownership. Included
in the current trend is the movement towards longer-term contracts for the
expanded array of services, e.g., 5 to 20 year contracts for facility
operations. These larger, longer contracts require us to have substantially
greater financial capital to remain competitive.
 
    We believe we provide our clients with innovative project delivery using
cost effective approaches and advanced technologies. We continuously monitor
acquisition and investment opportunities that will expand our portfolio of
services, add value to the projects undertaken for clients, or enhance capital
strength. We believe that we are well positioned geographically, technically
and financially to compete worldwide in the markets we have elected to pursue
and clients we serve.

                1998 Results of Operations Compared to 1997     
   
    Revenues for 1998 were $935.0 million compared to $917.6 million in 1997.
The increase of $17.4 million or 1.9% is comprised of significant improvements
in the Environmental, Energy & Infrastructure ("EE&I") segment of $25.9 million
and the Water segment of $52.9 million. These gains were reduced by the
decrease of $61.4 million in the Industrial segment revenues.     
   
    Pre-tax profit for 1998 was $14.4 million compared to $12.0 million in
1997. The increase of $2.4 million or 20.0% was primarily due to volume
increases in the EE&I and Water segments as well as a reduction in corporate
expenses. Contracts in the EE&I and Water segments generally have a lower
margin than the contracts in the Industrial segment, but increases in the
volume of contracts offset any decline generated by the Industrial segment.
    
   
    Bad debt expense was $57,000 in 1996, $1.4 million in 1997, and $5.2
million in 1998, which also impacts pre-tax profit. The increases in 1997 and
1998 relate to specific projects in the EE&I and Water segments that needed to
be reserved for due to the uncertainty of collection. This uncertainty results
from the instability of foreign economies.     
   
    The loss on the sale of assets in 1998 of $1.7 million also negatively
impacted pre-tax profit. This loss related to assets that were sold in closing
two of our offices.     
   
Environmental, Energy and Infrastructure     
   
    Revenues in the EE&I segment increased $25.9 million or 7.2% to $386.1
million in 1998, compared to $360.2 million in 1997. EE&I revenues accounted
for 39.0% of our total operating revenues in 1997 and 41.0% in 1998. During
1998 we benefited from the business development efforts undertaken in 1997. We
reported a full year of revenues in 1998 for public sector hazardous waste
remediation contracts awarded in 1997 by the Department of Defense and the
Department of Energy. Revenue growth from the Department of Defense was strong
in part due to legislation requiring military base closure and remediation. The
initial assessment phases are complete and the environmental remediation and
clean-up phases have begun.     
   
    The telecommunications markets, both domestically and internationally, also
attributed to the increase in revenues in 1998. We obtained several major
clients in this market providing program management oversight, site development
and construction management services to install or upgrade cable and wireless
networks and related infrastructure. With the technological advances in
wireless telecommunications, the ability to communicate rapidly via voice,
data, and video have become a necessity for business enterprises and
individuals around the world. We believe this market will provide continued
revenue growth in future years.     
   
    Although the private sector of the environmental and infrastructure market
slowed in 1997, we realized some recovery from this sector in 1998. We
attribute this growth to the strong domestic economy, which is affording
larger, multinational corporations the opportunity to improve their
environmental performance and sustainability.     
   
    The transportation market also contributed to the increase in revenues in
1998. We have benefited from the growth generated by the Intermodal Surface
Transportation Efficiency Act (ISTEA) adopted by Congress in 1991, which caused
significant increases in federal funding to the states for transportation
projects. We believe that we are also well positioned in the market to benefit
from the Transportation Equity Act for the 21st Century (TEA-21) which was
adopted by Congress in 1998. TEA-21 provides federal funding to the various
states for transportation infrastructure improvement projects including
construction-related projects for highways, highway safety, and transit for the
six-year period from 1998 to 2003.     
   
    The EE&I segment reported higher pre-tax profits in 1998, increasing from
$5.8 million in 1997 to $9.3 million in 1998, an increase of 60.3%. This profit
improvement was primarily achieved through the growth in the telecommunications
markets and also by successful cost containment efforts. The demand for
services is high in the telecommunications market, which can return higher
gross margins than the public and private sector environmental and
infrastructure contracts.     
   
    During 1998, cost containment measures enacted in prior years reduced
overhead costs as administrative functions have been consolidated to enable us
to manage our resources more effectively.

Water     
   
    Water segment revenues were $362.8 million in 1998 versus $309.9 million in
1997, an increase of $52.9 million or 17.1%. Approximately 30% of the increase
came from new contracts, with terms up to 15 years, in the utility plant
operations market for public and private clients. The balance of the increase
came from contract activities in water and wastewater infrastructure facility
improvement programs principally in the United States. The demand for the Water
segment's services continues to be strong as water and wastewater treatment
infrastructure improvement projects are undertaken by municipalities and other
utility authorities across the United States and abroad. The desire by
municipalities to preserve the environment and provide clean water creates a
demand for services we offer.     
   
    Profitability in the Water segment increased from $5.0 million in 1997 to
$7.2 million in 1998, an increase of 44.0%. Profitability continues to improve
as we continue to win significant new contracts and leverage overhead costs.
From year to year, we achieved increasing margins by focusing on improvements
in project delivery and effective cost management, even though competition in
this industry is increasing as a result of rapid consolidation. We believe that
our future success in the Water segment is dependent on continuing improvements
in our project delivery performance and our ability to win significant new
contracts.     
   
Industrial     
   
    The Industrial segment's revenues for 1998 were $186.1 million, of which
$141.4 million or 76.0% was generated from the microelectronics industry. The
Industrial segment's revenues for 1997 were $247.5 million, of which $222.8
million or 90% was generated from the microelectronics industry. Total revenues
for the Industrial segment declined $61.4 million from 1997 to 1998 due to
declines in the microelectronics industry offset by an increase in revenues
from other industries including, food, biopharmaceutical, fine chemical, and
facility services. The microelectronics industry began to reduce capital
spending in 1997 which has continued into 1999, resulting in a sharp decline in
purchases of engineering and construction services by our microelectronics
clients. In order to reduce its dependence on the microelectronics industry,
the Industrial segment has reallocated some of its workforce to focus on
diversifying into other industries mentioned above.     
       
   
    Pre-tax profits in the Industrial segment were $3.6 million in 1998 versus
$7.2 million in 1997. The decrease in the total volume of services sold during
1998 to the microelectronics industry caused this profit decline. In addition
to the impact of reduced volume, direct project costs as well as overhead
expenses affected profitability. Direct project costs, as a percentage of
revenues, decreased 2.0% in 1998 versus 1997, slightly improving gross margins.
Indirect labor costs, included in overhead expenses, as a percentage of gross
revenues, increased 4.0% from 1997 to 1998 because of the significant decline
in revenue during 1998.     
   
1997 Results of Operations Compared to 1996     
   
    Revenues for 1997 were $917.6 million compared to $937.2 million in 1996.
The decrease of $19.6 million or 2.1% resulted from a decline in the EE&I
segment revenues of $29.4 million and a decline in the Industrial segment
revenues of $10.8 million which were partially offset by improvements in Water
segment revenues of $20.6 million. Pre-tax profit remained unchanged overall.
    
   
Environmental, Energy and Infrastructure     
   
    Revenues for the EE&I segment were $360.2 million in 1997 versus $389.6
million in 1996, a decrease of $29.4 million or 7.5%. Included in revenues were
equity in earnings of investees accounted for by the equity method of $5.4
million in 1996 and $7.9 million in 1997.     
   
    The decrease in revenues from 1996 to 1997 was caused by the completion of
a significant transportation project and the decline in the private sector
environmental market. This decrease was offset by other gains in the
transportation sector and in the federal sector environmental market.     
   
    Excluding the revenues from the major project we completed, we actually
reported revenue growth in the transportation markets in the United States.
This revenue growth has been generated from the ISTEA bill that was passed in
1991, which provided significant increases in the level of federal funding for
transportation infrastructure projects across the nation.     


                                       23
<PAGE>
 
   
    The federal sector environmental market showed strong gains in 1997,
contributing 15% of total revenues versus 11.0% in 1996. Earlier marketing
efforts and favorable legislative developments resulted in significant project
wins from the Department of Defense.     
   
    Equity in earnings of investees accounted for under the equity method
related to this operating segment improved $2.5 million or 46.4% from 1996 to
1997. This increase in revenues was primarily generated from Kaiser-Hill
Company, LLC, a joint venture in which we own a 50% interest. 1997 was the
second full year on the contract and Kaiser-Hill's performance in meeting
certain measurable targets was rated higher than in 1996. At the end of 1995
and throughout the first half of 1996, Kaiser-Hill focused on the transition
from the former contractor and performed less of the plutonium stabilization
and cleanup. Kaiser-Hill has a Performance Based Management contract with the
Department of Energy which means that, except for a small base fee, the fees on
this contract are dependent on Kaiser-Hill's performance.     
   
    The decrease of $1.4 million in pre-tax profit from 1996 to 1997 is
primarily due to the completion of the significant transportation project and
an increase in overhead expenses. Although this project was completed, we made
a strategic decision to retain the workforce and incur a temporary reduction in
profits in anticipation of growth to be generated from TEA-21. We also
experienced an increase in general and administrative expenses due to
geographic expansion in 1997.     
   
Water     
   
    Water segment revenues were $309.9 million for 1997 versus $289.3 million
for 1996, an increase of $20.6 million or 7.1%. A significant portion of the
revenue increase was attributable to the utility plant operations market for
public and private clients. We continued to win substantial contracts that are
for longer terms and will contribute to revenues in future years. The balance
of the increase was attributable to contract activities in the water and
wastewater infrastructure facility improvement programs principally in the
United States.     
   
    The increase in pre-tax profits of $2.8 million resulted from an increase
in revenues, improved project performance and cost containment programs. During
1996, the water segment incurred more business development costs to ensure
steady growth in a market that is growing rapidly. During 1997, these marketing
efforts paid off as we added significant new contracts while leveraging our
cost structure and maintaining stable margins.     
   
Industrial     
   
    The Industrial segment's revenues for 1997 were $247.5 million, of which
90.0% was attributable to the microelectronics industry. The Industrial
segment's revenues for 1996 were $258.3 million, of which 97.0% was
attributable to the microelectronics industry. Total segment revenues declined
$10.8 million from 1996 to 1997. This decline was due to a $27.8 million
decrease in revenues from the microelectronics industry that was partially
offset by an increase in revenues of $17.0 million from other industries
including, food, biopharmaceutical, fine chemical, and facility services
markets. The microelectronics industry fostered significant growth for the
Industrial segment in past years by providing several very sizable projects
during 1995 and 1996. These large projects were substantially complete by mid-
1997 at which time the microelectronics industry entered into a period of
reevaluation of its capital expenditure plans, ultimately leading to a decline
in procurement of engineering and construction services during 1997.     
       
   
    Pre-tax profits in the Industrial segment were $7.2 million in 1997 versus
$8.2 million in 1996. This pre-tax profit decline of $1.0 million or 12.2% was
due primarily to the decrease in volume of services sold during 1997 to the
microelectronics industry. Direct project costs, as a percentage of revenues,
decreased 2.0% in 1997 versus 1996, slightly improving gross margins and
improving profitability. Total overhead costs, as a percentage of gross
revenues, increased 2.0% in 1997 versus 1996 offsetting the decrease in direct
project costs as a percentage of revenues.

Corporate Expenses
 
    Corporate expenses for 1996, 1997, and 1998 were $5.6 million, $6.0
million, and $5.7 million, respectively. These costs represent centralized
management costs that are not allocable to individual operating segments and
primarily include expenses associated with administrative compliance functions
such as legal, treasury, accounting, tax, and general business development
efforts. The fluctuations from year to year are generally dependent on the
business development efforts undertaken as other administrative costs
historically remained constant.
 
                                  Income Taxes
 
    Our income tax provisions for the last several years were as follows:

<TABLE> 
 
                             Income Tax            Effective
           Year               Provision            Tax Rate
<S>                          <C>                   <C>
           1998                $8,571                59.6%
           1997                $7,295                60.7%
           1996                $7,291                60.8%
</TABLE> 
 
    The effective tax rates are higher than the statutory tax rates since we
cannot deduct all foreign net operating losses on our U.S. income tax return.
We are also disallowed a tax deduction for portions of meals and entertainment
expenses that are considered necessary to conduct our business.
 
                        Liquidity and Capital Resources
 
Cash Flows From Operating Activities
   
    Operations generated $38.9 million of cash flows in 1997 and used $4.4
million in 1998. The decrease of $43.3 million from 1997 to 1998 was
attributable to the following working capital changes:     
 
  . revenue growth provided a corresponding increase in accounts receivable
 
  . prepaids increased as we contributed cash to our largest pension plan to
    maintain its funded status
 
  . billings in excess of revenues decreased due to a reduction in advance
    payments on contracts formerly realized in the Industrial operating
    segment
       
       
       
    In 1996 and 1997, operations generated $32.4 million and $38.9 million of
cash flows. The increase of $6.5 million from 1996 to 1997 was primarily
attributable to the change in working capital. Accounts receivable decreased
primarily due to the decline in revenues.
 
Cash Flows from Investing Activities
 
    Our business does not require significant capital expenditures. The capital
expenditures are generally for purchases of office equipment and leasehold
improvements. We spent $4.9 million in 1996, $2.6 million in 1997, and $4.7
million in 1998 on such expenditures. The decline in capital spending from 1996
to 1997 was largely due to a revamping of our procurement practices from
purchasing computer related assets to leasing such assets under favorable
operating lease terms. We have now established a formal operating lease program
under which most of our computing and related equipment is procured on an
ongoing basis. The increase in capital expenditures from 1997 to 1998 reflects
leasehold improvements for large regional office moves for which the leases had
expired.
 
Cash Flows from Financing Activities
 
    We have an unsecured loan agreement that provides for a credit facility of
$85.0 million, under which there were no amounts outstanding at December 31,
1998. If we do borrow money against this facility, the interest rates would
range from 5.4% to 7.8% at current terms. The revolving credit facility expires
December 31, 1999. We are in the process of renegotiating a new credit facility
for approximately $125.0 million. The increase in the facility will be
available to fund the growth in the business as well as to pursue acquisition
opportunities. We believe cash generated from operations and the existing
credit facilities will be sufficient to meet operating requirements for the
foreseeable future. Under our unsecured loan agreement, as of December 31,
1998, we had an outstanding term loan for $6.0 million, of which $4.0 million
will be paid in 1999. The interest rate on the loan is 7.1% and payments are
made quarterly.
 
                                       25
<PAGE>
 
   
    We also have a wholly-owned subsidiary that has an unsecured credit
facility of $9.5 million with interest payable on borrowings at prime rate. The
subsidiary has not used its facility for over three years.     
   
    We also had $22.5 million in 1997 and $20.6 million in 1998, in notes
payable to over 300 former shareholders in varying amounts over the next ten
years.     
   
Derivatives and Financial Instruments     
   
    We occasionally enter into forward contracts to hedge foreign currency
risks and not for speculative purposes. At December 31, 1997 and 1998, there
were no significant forward contracts outstanding. Generally, we do not have
derivative type instruments.     
 
                    New Accounting Standards Not Yet Adopted
 
    Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities," establishes fair value
accounting and reporting standards for derivative instruments and hedging
activities. We will adopt SFAS No. 133 in the first quarter of 2000. We are
currently assessing the effect of adoption, if any, on our financial position,
results of operations, and cash flows.
   
    Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities," requires costs of start-up activities, including organization
costs, to be expensed as incurred. We adopted this statement effective January
1, 1999, which did not have an impact on earnings.     
 
                              Year 2000 Compliance
 
    General. The upcoming turn of the century poses many challenges to
companies worldwide that rely on computers and/or programmed control devices to
operate their businesses or are suppliers or providers of time-sensitive
software or automated technology devices. The problems stem from the practice
of software writers, software vendors and equipment suppliers of using only two
digits to designate calendar year (e.g., 98 versus 1998) in automated
applications. That practice does not provide for proper recognition of the Year
2000 because computers and other automated equipment may interpret the two-
digit date "00" as, for example, 1900, rather than 2000. Consequently,
computers and other automated systems may cease operation or operate
incorrectly. This effect is commonly referred to as the "year 2000 problem."
   
    Several years ago, we recognized that the year 2000 problem could have a
significant adverse impact on our operations. We have, therefore, been actively
working to mitigate potential impacts on our internal operations as well as
working with our vendors and clients to identify and remediate potential year
2000 problems. Since 1997, we have been evaluating and taking steps to remedy
year 2000 problems in the following major areas of information technology and
other systems:     
          
  . Software: internal software and operating systems, including
    financial/management software, communications systems, facilities
    controls, design and other technical software     
     
  . Hardware: desktop computers and network servers     
     
  . Communications: local area networks, wide area networks and
    telecommunications systems     
     
  . Non-Information Technology Systems: power plant operating and control
    systems and facilities     
   
    Readiness. In order to assess our readiness, we identified four major
phases of our year 2000 compliance program. They are as follows:     
   
1. Inventory Phase.     
     
  . Identify functions that rely on computer systems that accept, create or
    manipulate calendar-related data     
     
  . Survey all significant vendors and facilities owners     
     
  . Identify all computer and communications hardware and software     
                                       26
<PAGE>
 
       
2. Assessment Phase.
   
  . Prioritize systems and functions that are critical to all lines of
    business, including management and human resource information systems,
    facilities, procurement, project delivery and billing systems     
   
  . Prioritize functions performed by each system and the level of
    susceptibility to date-sensitive information     
   
3. Remediation Phase.     
   
  . Make necessary repairs, replacements or implement contingency plans for
    the most critical systems     
   
  . Install third party application software upgrades     
   
4. Testing/Implementation Phase.     
       
   
  . Test systems to verify they are year 2000 compliant     
   
  . Place compliant systems into production     
   
    The following chart demonstrates our progress over time by phase for
each major area identified:     

             [CHART SHOWING Y2K REMEDIATION TIMELINE APPEARS HERE]

   
    External Vendors. We have contacted supply and service vendors with whom we
have material business to confirm the year 2000 compliance of their
applications, services and products that we rely on for operations.
Approximately 75% of major vendors responded by the end of 1998 and second
requests for compliance confirmation either have been sent or are in the
process of being sent to those that did not respond or that provided inadequate
responses. This portion of the evaluation is scheduled for completion in June
1999. Mission critical vendors such as our primary bank and payroll services
and landlords have responded adequately on the year 2000 compliance issue in
their services or products.     
   
    Clients of CH2M HILL. Because we are a service organization providing
design and operating services for a wide range of clients, we have actively
notified clients during the last half of 1998 of the need to be aware of
potential year 2000 problems in their operations. While we do not generally
provide year 2000 problem identification and remediation services to our
clients, we have suggested in the notifications that     
 
                                       27
<PAGE>
 
the clients recognize that problems could exist and an identification/
remediation program in their operations should be undertaken immediately if
not already done. We also made available to each client a list of year 2000
service firms via direct personal delivery or reference to a worldwide web
site we established for this purpose. Follow-up client reminders are being
done in instances where we operate facilities on behalf of clients that have
not confirmed to us that they have undertaken or completed compliance
verification activities.
       
   
   Worst Case Year 2000 Scenarios. The worst case scenario that could affect
our business is the failure of electric power and communications. We are
dependent on data and voice communication for delivery of our services, and on
electric power to conduct operations. Each of our regional offices and project
sites is vulnerable to business disruption from a local loss of power or
telecommunications. The most sensitive areas are our payroll system and our
water and wastewater treatment systems. We have contacted our critical
infrastructure suppliers regarding their preparedness and they have asserted
to us that they are year 2000 compliant. Although it does not appear that a
failure of electric power is likely based on assertions made to us, we have
developed the following contingency plans:     
   
  . Mobilize teams to our two communication hubs and data centers to
    constantly monitor critical infrastructure components as the date rolls
    over. This means having staff on-site during the entire holiday period
    and for as long afterwards as proves necessary to respond to needs on a
    priority basis     
   
  . Adjust payroll and accounting system schedules to complete processing
    prior to December 31, 1999 for the last pay period of the year     
   
  . Install a redundant link (with another supplier) to the Internet for
    enhanced messaging protection     
   
  . Install a diesel auxiliary power source at our main location in Denver,
    Colorado that can support the data center and telephone system for a
    minimum of 36 hours     
   
   With respect to the water and wastewater treatment facilities that we
operate in accordance with contractual service agreements, some of these
facilities have back up generators or duplicate power sources. If the power
supply is severed, the water treatment plants could not pump water and
customers would be without water for a period of time. As a contingency plan,
we are encouraging clients to fill above-ground water towers prior to December
31, 1999, and assisting in the preparation of water conservation plans.     
       
   
   It is also possible that the water and wastewater treatment plants will
have power but the computerized control systems fail. This could cause
"automatic" equipment to turn on or off and otherwise act in a manner that
upsets the chemical, mechanical, and biologic processes in the plants. To
mitigate this event, all facilities will be manned on December 31, 1999, and
operated in a manual mode if necessary.     
 
   Cost Estimates for Compliance Efforts. The total estimated costs for our
year 2000 remediation efforts was between $3.5 to $4.0 million as of December
31, 1998, of which we have spent approximately $2.5 million. Of the total
estimated cost, approximately $1.75 to $2.0 million represents the effort to
migrate our current systems to year 2000 compliant versions. All costs of year
2000 activities have been, and will in the future be, charged to current
operations as the costs are incurred.

             EMPLOYEE BENEFIT PLANS AND DIRECT STOCK PURCHASES     
   
   CH2M HILL maintains a number of plans that provide benefits to employees of
CH2M HILL and its affiliates. Under some of these plans, employees of CH2M HILL
and most of our affiliates may acquire common stock or beneficial interests in
common stock held in trusts. Employees may also purchase stock directly in the
internal market. The material provisions of the plans are summarized below in
general terms. We encourage you to read the plan documents, which will be made
available to you on request and which have been attached as exhibits to the

                      Retirement and Tax-Deferred Savings Plan
   
    The Retirement and Tax-Deferred Savings Plan, a 401(k) plan, is a profit
sharing plan that includes a cash or deferred arrangement that is intended to
qualify under Sections 401(a) and 401(k) of the Internal Revenue Code. This
means that contributions to the 401(k) plan receive favorable federal income
tax treatment.     
 
Employees Eligible to Participate in the 401(k) Plan
   
    All of our employees are eligible to participate in the 401(k) plan,
except:     
 
  . Leased employees
 
  . Temporary employees
     
  . Employees of affiliates that have not adopted the 401(k) plan     
   
    As of January 1, 1999, none of CH2M HILL's foreign affiliates have adopted
the 401(k) plan. Some, but not all, affiliates of CH2M HILL have adopted the
401(k) plan but have not adopted the provisions of the 401(k) plan relating to
defined contributions or matching contributions. CH2M HILL and its affiliates
that have adopted the 401(k) plan are referred to in this description as member
employers.     
 
Timing of Participation in the 401(k) Plan
   
    Each eligible employee can participate in the 401(k) plan with respect to
employee contributions and matching contributions, if applicable, beginning on:
    
  . The first date of hire, or
 
  . The first day of the first full pay period that begins on or after the
    employee's date of hire
   
    Each eligible employee begins to participate in the 401(k) plan with
respect to defined contributions, (if applicable), as of the first day of the
first month that begins on or after the eligible employee completes a twelve-
month period of service during which the employee is credited with at least
1,000 hours of service.     
 
Contributions to the 401(k) Plan
   
    Employee Contributions. The 401(k) plan allows a participant to elect to
defer a portion of the participant's compensation for a calendar year, subject
to limits, and to have that deferred amount contributed to the participant's
employee contribution account in the 401(k) plan.     
   
    Matching Contributions. Each Member Employer may, but is not required to,
make matching contributions each calendar quarter. Matching contributions may
be made in an amount that is based on a percentage of the employee's
contributions for the calendar quarter up to 3% of the employee's compensation,
or limited to a specified dollar amount per employee. Matching contributions to
the 401(k) plan may be made in cash or common stock.     
          
    Defined Contributions. Each member employer may, but is not required to,
make defined contributions to the 401(k) plan on behalf of that member
employer's employees. The amount of each member employer's annual defined
contribution, if any, is determined by the Board of Directors of CH2M HILL.
       
    Each member employer's defined contributions to the 401(k) plan are
allocated to the defined contribution accounts of eligible employees of that
member employer. A participant in the 401(k) plan is eligible to receive a
defined contribution for a calendar year if any of the following apply:     
     
  . The participant completed 1,000 hours of service during the calendar year
    and was employed by the member employer at the end of the calendar year
           
  . The participant retired during the calendar year at or after age 65 or
    age 55 if the participant has at least five years of service     
     
  . The participant died during the calendar year     
 
  . The participant became permanently disabled during the calendar year
   
    Each eligible participant receives a proportionate share of the member
employer's defined contribution for the calendar year. Each eligible
participant's proportionate share is determined by dividing that participant's
eligible compensation for the calendar year by the total eligible compensation
for the calendar year of all eligible participants. Eligible compensation is an
    
                                       30
<PAGE>
 
   
employee's basic hourly wage, times the number of regular hours worked during
the year. Eligible compensation for 1999 is limited to $160,000.     
   
    Rollover Contributions. Participants or potential participants may transfer
a rollover contribution from another qualified retirement plan to the 401(k)
plan.     
 
Investment of Contributions to the 401(k) Plan
   
    Matching contributions to the 401(k) plan, other than matching
contributions made by Operations Management International, Inc., are invested
in common stock.     
          
    Defined contributions to the 401(k) plan are initially invested in an
investment alternative selected by the trustees until direction is provided by
the participant. Participants in the 401(k) plan may direct the investment of
contributions that are allocated to their accounts, other than matching
contributions made by CH2M HILL and invested in CH2M HILL stock, among various
investment alternatives selected by the trustees of the 401(k) plan.     
    As of January 1, 2000, the investment alternatives offered by the trustees
will be as follows:
 
      Fidelity Retirement Government Money Market Portfolio
 
      CH2M HILL Fixed Income Fund
 
      Fidelity Balanced Fund
 
      Fidelity Equity-Income Fund
 
      Spartan U.S. Equity Index Fund
 
      Fidelity Magellan Fund
 
      Fidelity Growth Company Fund
 
      PIMCO Mid Cap Growth Fund
 
      Janus Worldwide Fund
 
      Company Stock Fund (invested in common stock of CH2M HILL)
 
    The following tables summarize, as of the dates indicated, the investment
performance of each of the investment funds for the last three years, except
for the Company Stock Fund, which did not exist during the last three years.
The summary is based on an initial investment of $100 in each investment fund
as of December 31, 1996. Past performance is not a guarantee of future results.
The funds may, therefore, perform worse or better in the future than they
performed in the past.

   Except for investments in the Company Stock Fund, participants may transfer
amounts among the investment alternatives in accordance with rules established
by the trustees.
 
   Amounts invested in the Company Stock Fund, other than matching
contributions, which are always invested in common stock, may be transferred
into other investment alternatives only as of a trade date. If a participant
wishes to transfer amounts invested in the Company Stock Fund into another
investment alternative as of a trade date, the trustees will direct the sale in
the internal market of an appropriate number of shares of common stock held in
the Company Stock Fund on that trade date. If only a portion of the common
stock offered for sale by the 401(k) plan in the internal market is sold, only
that portion of the participant's investment in the Company Stock Fund will be
transferred into the other investment alternatives. The remaining portion of
the participant's investment in the Company Stock Fund will remain in the
Company Stock Fund. Thus, a participant's ability to transfer amounts out of
the Company Stock Fund may be restricted. A participant considering an
investment in the Company Stock Fund should read this entire Prospectus,
particularly the sections entitled "Risk Factors" and "Internal Market
Information."
 
   Amounts invested in investment alternatives other than the Company Stock
Fund may not ordinarily be transferred into the Company Stock Fund. However,
the trustees may from time to time permit the transfer of amounts held in other
investment alternatives into the Company Stock Fund, subject to any
restrictions and conditions that the trustees deem to be appropriate.
 
   It is the current intent of the trustees to keep all amounts allocated to
the Company Stock Fund invested in common stock, except for cash reserves for
distributions and expenses.
 
Vesting in Accounts in the 401(k) Plan
 
   Each participant in the 401(k) plan is, at all times, 100% vested in amounts
allocated to the participant's rollover contribution account and employee
contribution account.
 
   Amounts allocated to a participant's defined contribution account and
matching contribution account are subject to the following vesting schedule:

   A participant's defined contribution account and matching contribution
account become fully vested if the participant is still employed by CH2M HILL
or an affiliate and any of the following occurs:     
     
  .  The participant reaches age 65 or age 55 if the participant has at least
    five years of service     
     
  . The participant becomes permanently disabled     
     
  . The participant dies     
 
Loans from the 401(k) Plan
 
   Loans from the 401(k) plan are available to any participant who is an active
employee of CH2M HILL or an affiliate. The total amount of a loan to a
participant from the 401(k) plan may not exceed $50,000. This $50,000 limit is
reduced by the participant's highest outstanding loan balance during the twelve
months before the date on which a loan is obtained. The total amount of a loan
to a participant in the 401(k) plan is further limited to 50% of the
participant's vested interest in the participant's accounts in the 401(k) plan.
The loan may not exceed the combined amount in the participant's employee
contribution account and rollover contribution account. The minimum loan amount
is $1,000. A participant may only have one loan outstanding at any time.
 
   A loan must be repaid within five years, unless the loan is used to acquire
the principal residence of the participant, in which case the term of the loan
may be up to 25 years. Loan payments must be repaid through payroll deductions.
Loans are secured by up to 50% of the participant's vested account balance in
the 401(k) plan. Loans bear interest at the interest rates in effect at the
CH2M HILL Federal Credit Union at the time the loan is granted.

Distributions and Withdrawals from the 401(k) Plan
   
    If a participant in the 401(k) plan terminates employment with us and if
the value of the vested portion of the participant's account in the 401(k) plan
does not exceed $5,000, the vested portion of the participant's account in the
401(k) plan will be distributed to the participant in a lump sum cash payment
as soon as reasonably practicable.     
   
    If a participant in the 401(k) plan terminates employment with us and if
the value of the vested portion of the participant's account in the 401(k) plan
is greater than $5,000, the participant may request an immediate distribution
or may elect to defer distribution until a later date. If distribution is
deferred, the participant's account will remain invested in accordance with the
401(k) plan until the participant requests distribution. In any case,
distribution from the 401(k) plan must begin when the participant reaches age
70 1/2.     
 
    A participant who has reached age 59 1/2 may request a distribution of the
participant's employee contribution account or the participant's rollover
account even if the participant has not terminated employment with CH2M HILL
and its affiliates.
   
    When a participant requests a distribution from the 401(k) plan, the
distribution will be made in cash in a lump sum as soon as reasonably
practicable. If the participant's account in the 401(k) plan includes common
stock, the portion of the participant's account invested in common stock will
be distributed in cash as soon as reasonably practicable after the common stock
is sold on the internal market or to CH2M HILL. CH2M HILL intends to purchase
from the 401(k) plan on each trade date sufficient common stock to permit
distributions to all participants whose requests for distributions are pending.
On some trade dates, however, CH2M HILL may not purchase from the 401(k) plan
sufficient common stock to permit distributions to all participants whose
requests for distributions are pending. In that case, distribution of some or
all of the portion of a participant's account invested in common stock may be
delayed until a subsequent trade date.     
   
    If a participant dies while employed by CH2M HILL or an affiliate,
distribution of the participant's account in the 401(k) plan will be made to
the participant's spouse or, if the participant's spouse has given proper
consent or if the participant has no spouse, to the beneficiary designated by
the participant. A surviving spouse of a deceased participant may delay
distribution of the participant's account in the 401(k) plan for up to five
years from the date of death. A distribution from the account will be made in
accordance with the procedures described in the previous paragraph.     
   
    The 401(k) plan permits a participant to obtain a hardship withdrawal from
the participant's employee contribution account or rollover contribution
account if there is an immediate and heavy financial need which may not
reasonably be met by the participant's other resources. The amount of a
hardship withdrawal may not exceed the amount required to meet the immediate
financial need, including any taxes or penalties resulting from the withdrawal,
and may be subject to various other limitations.     
 
                              Employee Stock Plan
   
    The employee stock plan was originally adopted in 1977 as an employee stock
ownership plan, or ESOP. In 1983 the ESOP was converted into a profit sharing
plan designed to invest up to 100% of its assets in stock of CH2M HILL. The
employee stock plan is a profit sharing plan that is intended to qualify under
Section 401(a) of the Internal Revenue Code. This means that contributions to
the employee stock plan receive favorable federal income tax treatment.     
 
Employees Eligible to Participate in the Employee Stock Plan
   
    All of our employees are eligible to participate in the employee stock
plan, except:     
 
  . Leased employees
 
  . Temporary employees
 
  . Employees of affiliates that have not adopted the Employee Stock Plan
   
    As of January 1, 1999, none of CH2M HILL's foreign affiliates have adopted
the Employee Stock Plan. CH2M HILL and each affiliate that has adopted the
employee stock plan are referred to as member employers.     

 
                                       34
<PAGE>
 
 
    Each eligible employee begins to participate in the employee stock plan
after completing a twelve-month period of service with a Member Employer during
which the eligible employee is credited with at least 1,000 hours of service.
 
Contributions to the Employee Stock Plan
 
    For each calendar year, each Member Employer may, but is not required to,
make a contribution to the employee stock plan. The amount of each Member
Employer's contribution to the employee stock plan, if any, for a calendar year
is determined by the Board of Directors of CH2M HILL. For the calendar year
ended December 31, 1998, member employers contributed a total of $3.5 million
to the employee stock plan. Employees are not permitted to make contributions
to the employee stock plan.
 
    Each member employer's contribution to the employee stock plan for a
calendar year is allocated to the accounts of eligible employees of that member
employer who are participants in the employee stock plan.
 
    Each eligible participant receives a proportionate share of the member
employer's contribution for the calendar year. Each eligible participant's
proportionate share is determined by dividing that participant's eligible
compensation for the calendar year by the total eligible compensation for the
calendar year of all participants.
 
    Eligible compensation is an employee's basic hourly wage, times the number
of regular hours worked during the year. Eligible compensation for 1999 is
limited to $160,000.
 
    Forfeitures, if any, of the nonvested portion of accounts of terminated
participants are allocated to the accounts of remaining eligible participants.
 
Investment of the Assets of the Employee Stock Plan
 
    The employee stock plan is authorized to invest up to 100% of its assets in
common stock. Cash contributions to the employee stock plan will be used to
purchase common stock through the internal market on the next trade date, to
the extent that common stock is available for purchase on that trade date. If
common stock is not available for purchase on that trade date, cash
contributions will be held until common stock is available for purchase.
 
    It is the intent of CH2M HILL that, to the maximum extent possible, all of
the assets of the employee stock plan will be invested in common stock at all
times. Any cash in the employee stock plan will be invested in an investment
vehicle selected by the trustees.
 
Vesting of Accounts in the Employee Stock Plan
 
    Amounts contained in a participant's account in the employee stock plan are
subject to the following vesting schedule:
 
                              [CHART APPEARS HERE]
 
    A participant also becomes fully vested if the participant is still
employed by CH2M HILL or an affiliate when the participant:
 
  . Reaches age 65 or age 55 if the participant has at least five years of
    service
 
  . Becomes permanently disabled
 
  . Dies
 
Loans from the Employee Stock Plan
 
    Loans are not available to a participant from the employee stock plan.
 
Distributions from the Employee Stock Plan
 
    If a participant's employment with us terminates and the vested portion of
the participant's account in the employee stock plan does not exceed $5,000,
the vested portion of the participant's account will be distributed to the
participant in a lump sum cash payment as soon as practicable after the next
trade date. If a

participant's employment with us terminates and the vested portion of the
participant's account in the employee stock plan is greater than $5,000, the
participant may request a distribution or may elect to defer distribution of
the account until a later date. If distribution is deferred, the participant's
account will remain invested in common stock until the participant requests
distribution.     
 
    If a participant dies while employed by us, distribution of the
participant's account in the Employee Stock Plan will be made to the
participant's surviving spouse or, if the participant's surviving spouse has
given proper consent or if the participant has no surviving spouse, to the
beneficiary designated by the participant. Distributions to a surviving spouse,
or a beneficiary will be made in the same manner.
 
    CH2M HILL intends to purchase from the Employee Stock Plan at each trade
date sufficient common stock to permit distribution covering all pending
requests for distributions. On some trade dates, CH2M HILL may not purchase
from the Employee Stock Plan sufficient common stock to permit distribution
covering all pending distribution requests. In that case, distribution of a
participant's account from the Employee Stock Plan may be delayed to a
subsequent trade date.
 
       General Provisions of the 401(k) Plan and the Employee Stock Plan
   
    The following is a summary of the material provisions of the 401(k) plan
and the employee stock plan:     
 
Contribution Limitations
   
    The maximum contribution for any calendar year which CH2M HILL or its
affiliates may make to either the 401(k) plan or the employee stock plan for
the benefit of a participant, including employee contributions to the 401(k)
plan, plus forfeitures, may not exceed the lesser of $30,000 or 25% of the
participant's compensation for the calendar year. The $30,000 limit will be
adjusted for cost of living in accordance with rules of the Secretary of the
Treasury.     
 
Administration
   
    The 401(k) plan and the employee stock plan are administered by the
trustees. The trustees have the power to supervise each plan's operations,
including the power and authority to do all of the following:     
     
  . Allocate fiduciary responsibilities among the fiduciaries of each of the
    plans     
     
  . Designate agents to carry out responsibilities relating to each of the
    plans     
     
  . Employ legal, actuarial, accounting, and other assistance as the trustees
    may deem appropriate in carrying out the terms of each of the plans     
     
  . Establish rules and regulations for the administration of each of the
    plans     
     
  . Administer, interpret, construe and apply the plans and determine
    questions relating to eligibility, the amount of any participant's
    service and the amount of benefits to which any participant or
    beneficiary is entitled     
     
  . Determine the manner in which each of the plans' assets are disbursed
        
Pass-Through Voting and Tendering of Common Stock
   
    Each participant in the 401(k) plan and the employee stock plan has the
right to instruct the trustees on a confidential basis how to vote the
participant's interest in common stock held in the plans. The trustees will
vote all allocated shares held in the plans as to which no voting instructions
are received, together with all unallocated shares held in each of the plans,
in the same proportion, on a plan-by-plan basis, as the allocated shares for
which voting instructions have been received are voted. The trustees are
required to notify participants of their pass-through voting rights prior to
each meeting of shareholders.     
   
    In the event of a tender or exchange offer for the common stock, each
participant in the 401(k) plan and the employee stock plan has the right to
instruct the trustees on a confidential basis whether or not to tender or
exchange the participant's proportionate interest in common stock held in the
plans. The trustees will not     
 
                                       36
<PAGE>
 
   
tender or exchange any allocated shares unless instructions are received from
participants. Shares held in the plans which have not yet been allocated to the
accounts of participants will be tendered or exchanged by the trustees, on a
plan-by-plan basis, in the same proportion as the allocated shares held in each
plan are tendered or exchanged.     
   
    The trustees' duties with respect to voting and tendering of common stock
are governed by the fiduciary provisions of the Employee Retirement Income
Security Act of 1974 ("ERISA"). These fiduciary provisions of ERISA may
require, in limited circumstances, that the trustees override the votes, or
decisions whether or not to tender, of participants with respect to common
stock and to determine, in the trustees' best judgment, how to vote the shares
or whether or not to tender the shares.     
   
Trustees of the 401(k) Plan and the Employee Stock Plan     
   
    The current trustees of the 401(k) plan and the employee stock plan are
Fred K. Berry, Samuel H. Iapalucci, Stan Vinson, Sharon Schlechter, and Cliff
Thompson, all of whom are officers of the Company or its affiliates.     
   
    Generally, the trustees have all the rights afforded a trustee under
applicable law. Subject to limitations in the plans, the trustees' rights
include, but are not limited to, the right to:     
     
  . Invest and reinvest the funds held in the plans' trusts in any investment
    of any kind     
     
  . Retain or sell the securities and other property held in the plans'
    trusts     
     
  . Consent or participate in any reorganization or merger in regard to any
    corporation whose securities are held in the plans' trusts (subject in
    the case of the common stock to the participants' pass-through voting
    rights and right to instruct the trustees in the event of a tender or
    exchange offer)     
            
  . Exercise all the rights of the holder of any security held in the plans'
    trusts, including the right to vote such securities (subject, in the case
    of the common stock, to the participants' pass-through voting rights)
        
       
  . Vote proxies and exercise any other similar rights of ownership
     
  . Lend to participants in the plans such amounts as may be permitted under
    the plans     
   
    The trustees receive no compensation from the plans for their service as
trustees of the plans. Expenses incurred in the establishment, administration
and operation of the plans are paid by the respective plans unless CH2M HILL
elects to pay such expenses.     
 
Administrative Services
   
    CH2M HILL has entered into an agreement with Fidelity Institutional
Retirement Services Company to provide recordkeeping and other administrative
services to the 401(k) plan and the employee stock plan. Fidelity's fees for
these services are paid by each of the plans.     
 
Account Statements
   
    Each participant is furnished with a quarterly statement of the
participant's account in the 401(k) plan and with an annual statement of the
participant's account in the employee stock plan.     
 
Amendment and Termination
   
    CH2M HILL has reserved the right to amend each of the plans at any time,
for any reason and without prior notice, except that no such amendment may have
the effect of:     
     
  . Generally causing any assets of the plans' trusts to be used for or
    diverted to any purpose other than providing benefits to participants and
    their beneficiaries and defraying expenses of the plans, except as
    permitted by applicable law     
 
  . Depriving any participant or beneficiary, on a retroactive basis, of any
    benefit to which they would otherwise be entitled had the participant's
    employment with us terminated immediately prior to the amendment
 
  . Increasing the liabilities or responsibilities of the trustees without
    their written consent
 
                                       37
<PAGE>
 
   
    CH2M HILL has also retained the right to terminate either of the plans at
any time and for any reason. In addition, CH2M HILL may discontinue
contributions to the plans, but any such discontinuation does not automatically
terminate the plans as to funds and assets then held by the trustees.     
 
ERISA
   
    The 401(k) plan and the employee stock plan are both subject to ERISA,
including reporting and disclosure obligations, fiduciary standards and
prohibited transaction rules. Since the plans are individual account plans
under ERISA, they are not subject to the jurisdiction of the Pension Benefit
Guaranty Corporation under Title IV of ERISA and none of the plans' benefits
are guaranteed by the Pension Benefit Guaranty Corporation.     
 
Federal Income Tax Consequences
   
    The following paragraphs summarize the material federal income tax
consequences of participating in the 401(k) plan and the employee stock plan.
This summary is intended to be general and is not intended to address every
federal income tax issue that may arise from participation in the plans. This
summary does not address state or local tax issues, which may be significant.
Each participant in the plans should consider obtaining professional tax advice
with respect to the plans' tax impact on that participant.     
   
    Each of the plans is intended to qualify under Section 401(a) of the
Internal Revenue Code. Qualification under Section 401(a) of the Internal
Revenue Code generally produces the following federal income tax results with
respect to contributions, income and earnings, and distributions and loans
from, the plans.     
   
    Contributions to the 401(k) Plan and the Employee Stock Plan. A participant
will not be subject to federal income tax on CH2M HILL contributions to the
plans at the time those contributions are made.     
   
    A participant in the 401(k) plan who makes employee contributions will
exclude the amount of those employee contributions from the participant's gross
income.     
   
    Neither the participant nor CH2M HILL will be subject to federal employment
taxes on CH2M HILL contributions to the Plans. Employee contributions to the
401(k) plan will be subject to federal employment taxes.     
   
    The plans will not be subject to federal income tax on contributions made
to the plans by CH2M HILL.     
   
    Subject to limits contained in each of the plans, CH2M HILL will be able to
deduct the amounts that it contributes to the plans, including amounts
contributed to the 401(k) plan as employee contributions. The amount of CH2M
HILL's deduction will generally be equal to the amount of the contributions.
    
   
    Income and Appreciation of the 401(k) Plan and the Employee Stock Plan.
Participants will not be subject to federal income tax on income or
appreciation in their accounts in the plans until distributions are made or
deemed to be made to the participant.     
   
    The plans will not be subject to federal income tax on their income or
appreciation, except to the extent that the plans realize unrelated business
taxable income.     
   
    Distributions from the 401(k) Plan and the Employee Stock Plan.
Distributions from the plans will be subject to federal income tax under
complex rules that apply generally to distributions from all tax-qualified
retirement plans.     
   
    In general, a distribution from either of the plans will be taxable in the
year of receipt as ordinary income unless the recipient is eligible for and
elects to make a qualifying "rollover" to an individual retirement account or
to another qualified plan.     
   
    An early distribution from the plans will result in an additional 10% tax
on the taxable portion of the distribution. Early distributions are all
distributions made before the participant has reached age 59 1/2 unless:     
 
  . The participant is permanently disabled

 
                                       38
<PAGE>
 
 
  . The distribution is made after termination of employment due to the death
    of the participant
 
  . The distribution is made after termination of employment to a participant
    who terminated employment during or after the calendar year the
    participant attained the age of 55
 
    Exceptions from the 10% additional tax apply to distributions that are
rolled over to an individual retirement account or to another qualified plan
and to distributions that are used for deductible medical expenses.
 
    A participant, or the participant's spouse in the event of the
participant's death, who receives a distribution from the plans, other than
mandatory distributions after age 70 1/2, and wishes to defer immediate tax on
the distribution, may transfer or "rollover" all or part of the distribution to
an individual retirement account. The participant may rollover the distribution
to another qualified retirement plan. To be effective, the rollover must be
completed within 60 days of receipt of the distribution. Alternatively, the
participant or spouse may request a direct transfer from the plans to an
individual retirement account or, in the case of the participant, to another
qualified retirement plan.
 
    A participant or a participant's spouse who does not arrange a direct
transfer to an individual retirement account or to another qualified plan will
be subject to federal income tax withholding at a rate of 20% of the
distribution, even if the participant or spouse later makes a rollover.
 
    A participant or the participant's spouse who makes a valid rollover to an
individual retirement account or to another qualified plan will defer payment
of federal income tax until such time as such participant or spouse actually
begins to receive distributions from the individual retirement account or other
qualified plan.
 
    Loans from the 401(k) Plan. A loan from the 401(k) plan is generally not
considered to be a distribution and is not subject to federal income tax when
made. Interest paid by the participant on a loan from the 401(k) plan will
generally not be deductible.
 
                             1999 Stock Option Plan
 
    The Board adopted the 1999 Stock Option Plan on November 6, 1998. The stock
option plan is not subject to ERISA. The shareholders of CH2M HILL approved the
stock option plan on December 18, 1998. The stock option plan was effective as
of January 1, 1999.
 
            [GRAPHIC DESCRIBING "WHAT IS AN OPTION?" APPEARS HERE]
 
Administration of the Stock Option Plan
 
    The stock option plan is administered by the Ownership and Incentive
Compensation Committee ("O&IC Committee"). The O&IC Committee is appointed by
the Board of Directors. The O&IC Committee consists of two or more members of
the Board of Directors and other individuals appointed by the Board of
Directors.
 
    The following individuals are the current members of the O&IC Committee:
Ralph R. Peterson, Philip G. Hall, Susan D. King, Donald S. Evans, Kenneth F.
Durant, Joseph A. Ahearn, Michael D. Kennedy, Michael Y. Marcussen, Steve
Guttenplan, James J. Ferris, Jill T. Shapiro Sideman, Cliff Thompson and Craig
T. Zeien.
 
    The O&IC Committee decides which of our eligible employees will be granted
options to buy common stock under the stock option plan. The O&IC Committee
also determines all of the terms and conditions of each stock option granted
under the stock option plan, such as:
 
  . The manner in which the stock option may be exercised


 
                                       39
<PAGE>
 
  . Whether there are conditions that must be met before the stock option may
    be exercised
 
  . The exercise price that must be paid in order to buy common stock upon
    exercise of each stock option
 
  . When the stock option becomes vested and may be exercised
 
   We intend to grant stock options at the fair market value of the common
stock on the day that a stock option is granted, which is the formula price for
the common stock in effect at the time of the grant. In any case, the exercise
price cannot be less than 90% of the fair market value of the common stock on
the day that the stock option is granted. Although the Stock Option Plan
permits the issuance of both "incentive" and "nonqualified" stock options, the
O&IC Committee does not intend to issue incentive stock options, and no
incentive stock options will be granted unless we first provide appropriate
disclosure to potential recipients.
 
   The O&IC Committee is not required to provide the same terms and conditions
in each stock option agreement. Stock options granted to different employees or
at different times may contain different terms and conditions, including
different exercise prices.
 
Limits on Stock Options Granted Under the Stock Option Plan
 
   Under the stock option plan, the O&IC Committee may grant cancellable stock
options for up to 8,000,000 shares of common stock, subject to adjustments. As
of May 1, 1999, 2,434,840 stock options had been issued under the stock option
plan.
 
Stock Options May Be Restricted
 
   The O&IC Committee may provide in the grant of a stock option that the
exercise of the stock option is restricted or conditional. For example, the
O&IC Committee may provide in the grant of a stock option that the stock option
cannot be exercised unless the optionee agrees to sell the common stock
acquired as a result of the exercise in the internal market on the next trade
date or agrees to transfer the common stock acquired to the after-tax deferred
compensation trust.

             [Graphic describing "What is Vesting?" APPEARS HERE]
 
Exercise of Stock Options
 
   If the O&IC Committee grants a stock option to an employee, the employee may
exercise the stock option after all conditions described in the stock option
agreement, including vesting, have been met and before the stock option
expires.
 
   The employee may exercise a stock option by following the procedures for
exercise described in the stock option agreement. These procedures will include
providing written notice of exercise to CH2M HILL, paying the exercise price,
and paying any amount required for federal, state, or local income tax
withholding as a result of the employee's exercise of the stock option as
described below. The procedures may also include other requirements imposed by
the O&IC Committee from time to time.
 
Payment for Common Stock Bought Pursuant to the Exercise of a Stock Option
Granted Under the Stock Option Plan
 
   Payment for shares of common stock bought pursuant to the exercise of a
stock option may be made in cash or a personal check payable to CH2M HILL.
 
   Unless the O&IC Committee provides otherwise, payment may also be made by
returning to CH2M HILL shares of common stock already owned by the employee. If
the employee uses shares of common stock the employee

 
                                       40
<PAGE>
 
already owns as payment for the exercise of a stock option, then the number of
shares given to the employee as a result of the exercise will be the net
number. The net number will be the difference between the number of shares
bought through the exercise of the stock option and the number of shares
already owned by the employee and used as payment for the exercise.

                         Examples of Option Exercises

Assumptions:
 . Employee was granted 100 options at an exercise price of $10 per share
 . Employee exercises 100 options with an exercise price of $10 per share when 
  the formula price is $20 per share
 . Employee already owns 200 shares of common stock
 . Combined federal, state and FICA tax rate is 42%

</TABLE> 

The shares exchanged in a stock-for-stock transaction are treated as a "Like 
Kind" exchange which does not trigger the recognition of capital gains. The 
shares exchanged carry their original tax basis and acquisition date. Newly
acquired shares have a basis equal to the fair market value at the time of
exercise. The shares sold to pay taxes represent new shares acquired through the
exercise of the option and would therefore not trigger any capital gains.

   Payment may also be made in a combination of cash, a personal check, and
shares of common stock, unless the O&IC Committee provides that payment by
shares of common stock will not be allowed. If shares of common stock owned by
the employee are used to pay all or part of the purchase price, the value
assigned to each share will be equal to the formula price of the common stock
on the date of exercise of the stock option.
 
Expiration of Stock Options Granted Under the Stock Option Plan
 
   A stock option granted to an employee may not be exercised after the stock
option expires. A stock option expires on the expiration date set forth in the
stock option agreement. The O&IC Committee generally intends to grant stock
options that expire five years after the date on which the stock options are
granted.
 
   Regardless of the date stated in the stock option agreement, a stock option
granted under the stock option plan and not previously exercised will
terminate when the employee terminates employment with us, unless the stock
option agreement provides that the stock option may be exercised after
termination of employment.
 
   The O&IC Committee generally intends to permit the exercise of a stock
option granted

                                      41
<PAGE>
 
   
under the stock option plan within thirty days after termination of employment
with us for any reason other than for cause. If an employee terminates
employment with us due to disability or death, the O&IC Committee generally
intends to permit the stock option to be exercised within one year after the
date on which the employee's employment terminates due to the disability or
death.     
   
    An employee may work for an affiliate of CH2M HILL that becomes ineligible
to participate in the stock option plan. For example, an affiliate may become
ineligible to participate because CH2M HILL's interest in the affiliate is
sold. In that case, stock options held by the employee will become immediately
exercisable, but the employee will be considered to terminate employment with
us on the day that the affiliate becomes ineligible to participate in the stock
option plan. Therefore, the employee will be able to exercise the stock options
only if and to the extent that the stock option agreement permits the employee
to exercise the stock options on termination of employment.     
 
Amendment and Termination of the Stock Option Plan
   
    The Board of Directors may amend or terminate the stock option plan at any
time. Any amendment or termination of the stock option plan will not change the
terms of any stock option agreement already in place at the time of such
amendment or termination unless the employee agrees to such change. The
following changes may not be made by the Board without shareholder approval:
    
   
  . Increasing the number of shares of common stock available under the stock
    option plan     
   
  . Reducing the minimum price at which stock options may be granted under
    the stock option plan     
   
  . Changing the class of employees who may be granted stock options under
    the stock option plan     
   
    The stock option plan will terminate on December 31, 2008. No stock options
will be granted under the stock option plan after that date. Any stock option
agreement already in place on December 31, 2008, will remain in effect until
the stock options covered by that stock option agreement are exercised or
expire.     
 
Corporate Reorganization, Sale of Assets, or Change in Control
 
    If CH2M HILL experiences a stock split, a stock dividend, a
recapitalization, or a similar transaction that changes the number of
outstanding shares of common stock without receipt of payment by CH2M HILL, the
O&IC Committee will adjust the number of shares of common stock that may be
bought under outstanding stock options and the exercise price that must be paid
to buy shares of common stock under outstanding stock options, in order to
reflect the change in the common stock.
   
    If a change in control of CH2M HILL occurs, then all outstanding stock
options granted under the stock option plan may be exercised immediately, even
if the conditions on exercise stated in the stock option agreement have not
been met. A change in control of CH2M HILL occurs when one person or a group of
persons, other than an employee benefit plan, acting jointly, acquires at least
50% of the common stock, or when CH2M HILL agrees to a merger in which CH2M
HILL is not the surviving company, or when CH2M HILL disposes of more than 50%
of its assets, measured by the value of the assets. The O&IC Committee will
determine whether a change in control of CH2M HILL has occurred.     
 
    For example, if CH2M HILL experiences a merger, liquidation,
reorganization, or similar transaction in which CH2M HILL is not the surviving
corporation, the O&IC Committee will either:
 
  . Convert outstanding stock options into comparable options to buy stock in
    the surviving corporation; or
 
  . Require that outstanding stock options be exercised within a specific
    period of time before the effective date of the transaction or be
    forfeited.
   
    In connection with the transaction, if there is not a change in control of
CH2M HILL, the O&IC Committee may, but is not required to, provide that any
outstanding stock options granted under     

 
                                       42
<PAGE>
 
 
the stock option plan may be exercised immediately, even if the conditions on
exercise stated in the stock option agreement have not been met.
 
Federal, State, and Local Income Tax Withholding
 
    The federal income tax consequences of the grant and exercise of stock
options under the stock option plan are described below. Sometimes the exercise
of a stock option or the sale of shares of common stock bought through the
exercise of a stock option may produce compensation income to an employee. In
that case, your employer may be required to withhold federal, state, and local
income taxes with respect to the amount of compensation income you recognized,
as though that amount was paid to you by your employer. Your employer may
satisfy this withholding obligation by withholding the required amount from
other amounts, such as other compensation or wages, your employer paid to you.
Alternatively, your employer may require you to pay the amount necessary to
satisfy the withholding obligation. The payment of the amount necessary to
satisfy the withholding obligation may be a prerequisite to the exercise of a
stock option granted under the stock option plan.
 
           [GRAPHIC DESCRIBING "ARE OPTIONS TAXABLE?" APPEARS HERE]
 
Federal Income Tax Consequences of Stock Options Granted under the Stock Option
Plan
 
    This summary of the material federal income tax consequences of the grant
and exercise of stock options under the stock option plan does not address
every federal income tax issue that may arise and does not address foreign,
state or local tax issues, which may be significant.
 
    This summary does not address the tax consequences for incentive stock
options because the O&IC Committee does not intend to grant incentive stock
options.
 
    Each holder of stock options granted under the stock option plan should
consider obtaining professional tax advice with respect to the tax impact of
their stock options.
 
    Exercise of Nonqualified Stock Options with Cash. Generally, an individual
will not be taxed when a stock option is granted. Instead, at the time the
individual exercises a stock option, the individual will recognize ordinary
income for federal income tax purposes. The amount of ordinary income
recognized by the individual will be equal to the excess of the fair market
value of the common stock at the time of exercise over the exercise price. CH2M
HILL generally will be entitled to a federal income tax deduction at that time
and in the same amount that the individual realizes as ordinary income.
 
    If common stock bought through the exercise of a stock option is later sold
or exchanged, then the difference between the sale price and the fair market
value of the common stock on the date of exercise will be recognized as gain or
loss to the seller. If the common stock is a capital asset in the seller's
hands, the gain or loss on the sale will be long-term or short-term capital
gain or loss, depending on whether the holding period for the common stock at
the time of sale is more than 12 months or 12 months or less, respectively.
 
    Exercise of Nonqualified Stock Options With Shares of Common Stock. If
payment of the exercise price under a stock option is made by surrendering
previously owned shares of common stock, the following rules apply:
 
  . No gain or loss will be recognized as a result of the tendering of shares
    in exchange for an equal number of shares available through the exercise
    of nonqualified stock options
 
  . Any additional shares received will be taxed as ordinary income in an
    amount equal to the fair market value of the shares at the time of
    exercise

                1999 Payroll Deduction Stock Purchase Plan     
   
    We have recently established the stock purchase plan for the benefit of our
employees and employees of certain of our affiliates. The stock purchase plan
provides for the purchase of common stock through payroll deductions by
participating employees. The stock purchase plan is intended to qualify under
Section 423 of the Internal Revenue Code. Under the stock purchase plan, the
O&IC Committee may decide to let employees begin payroll deductions for
purchases of common stock as early as October 1, 1999. However, no common stock
will be purchased under the stock purchase plan until after January 1, 2000.
The Stock Purchase Plan is not subject to ERISA.     
 
                   Administration of the Stock Purchase Plan
   
    The stock purchase plan is administered by the O&IC Committee, which is the
same committee that administers the stock option plan, described above.     
   
    The O&IC Committee decides which affiliates of CH2M HILL will be eligible
to participate in the stock purchase plan. The O&IC Committee also decides
whether employees must meet eligibility requirements in order to participate in
the stock purchase plan.     
   
    The O&IC Committee may adopt rules for the administration of the stock
purchase plan. The O&IC Committee interprets the stock purchase plan. The O&IC
Committee's decisions on any questions that arise under the stock purchase plan
are binding on all persons, including CH2M HILL and any employee who
participates in the stock purchase plan.     
 
          Employees Eligible to Participate in the Stock Purchase Plan
   
    Generally, all employees of CH2M HILL and any participating affiliate may
participate in the stock purchase plan. The O&IC Committee decides which
affiliates of CH2M HILL may participate in the stock purchase plan.     
   
    The O&IC Committee intends to exclude employees who normally work less than
20 hours per week and employees who normally work five or fewer months in a
year from participating in the stock purchase plan.     
   
    Any employee who owns five percent or more of CH2M HILL or of any
subsidiary of CH2M HILL is excluded from participating in the stock purchase
plan.     
   
    An employee who terminates employment with CH2M HILL and all participating
affiliates is no longer eligible to participate in the stock purchase plan. For
this purpose, termination of employment includes death, disability, retirement,
transfer to an affiliate that is not eligible to participate in the stock
purchase plan, or any other termination of employment. If an employee becomes
ineligible to continue participating in the stock purchase plan, any amount
held in the employee's stock purchase account will be distributed to the
employee.     
 
                    Participating in the Stock Purchase Plan
   
    In order to participate in the stock purchase plan, an employee must
deliver a written payroll deduction authorization form to the plan
administrator of the stock purchase plan. The payroll deduction authorization
form will tell the eligible employee's employer to withhold a specific
percentage of the eligible employee's pay to be used to buy common stock under
the stock purchase plan. The payroll deduction authorization form must provide
for the deduction of at least 1% of the employee's pay, but no more than 10% of
the employee's pay, in a whole number percentage. The employee may change the
specified percentage at any time. However, an employee cannot purchase more
than $25,000 of common stock under the stock purchase plan in any calendar
year.     
 
Purchases of Common Stock Under the Stock Purchase Plan
   
    No shares of common stock will be bought under the stock purchase plan
until after January 1, 2000, even though the O&IC Committee may decide to allow
employees to have amounts deducted from their paychecks and contributed to
their stock purchase accounts during the last quarter of 1999. Beginning in
2000, CH2M HILL will use the amount in the employee's stock purchase account to
buy common stock for the employee on each trade date.     
 
                                       44
<PAGE>
 
   
    Each year, the Board of Directors will decide what percentage of the
purchase price of common stock CH2M HILL will contribute toward the purchase of
common stock under the stock purchase plan during that year. CH2M HILL's
percentage may be as low as 0% or as high as 15%. As of January 1, 2000, CH2M
HILL's percentage will be 10%. We will not actually contribute any amount to
the employee's payroll deduction stock purchase account. Instead, we will add
the contribution percentage to the amount in the employee's stock purchase
account and use the combined amount to purchase common stock on each trade
date. We will either buy the common stock on each trade date in the internal
market, if available, or we will issue new shares of common stock.     
 
Reservation of Common Stock for Purchase Under the Stock Purchase Plan
   
    CH2M HILL has reserved 1,000,000 shares of common stock to be sold under
the stock purchase plan. This is in addition to any shares of common stock
bought in the internal market under the stock purchase plan. The number of
shares of common stock reserved for sale under the stock purchase plan can be
changed by the O&IC Committee to reflect any stock split, stock dividend,
recapitalization, or similar transaction that CH2M HILL may experience.     
 
Distribution of Common Stock Bought Through the Stock Purchase Plan
   
    When shares of common stock are bought through the stock purchase plan,
they will initially be held by CH2M HILL in the name of the employee. Before
the next vote of shareholders, the shares of common stock bought through the
stock purchase plan will be distributed to the employee. The employee may
petition the O&IC Committee for an earlier distribution of the shares.     
 
Restrictions on Common Stock Bought Through the Stock Purchase Plan
   
    All shares of common stock bought through the stock purchase plan will be
subject to the restrictions on common stock contained in CH2M HILL's Restated
Bylaws. Those restrictions are described below, in the section of this
Prospectus called "Description of Capital Stock."     
   
    An employee is not permitted to purchase common stock under the stock
purchase plan if doing so would cause the employee to own more shares of common
stock than the employee is permitted to own under CH2M HILL's Restated Bylaws.
    
Amendment and Termination of the Stock Purchase Plan
   
    The Board of Directors of CH2M HILL may amend or terminate the stock
purchase plan at any time. However, the Board of Directors may not increase the
number of shares of common stock reserved for sale under the stock purchase
plan unless the shareholders of CH2M HILL also approve that change.     
   
    Unless previously terminated by CH2M HILL, the stock purchase plan will
terminate on December 31, 2008.     
 
Federal, State, and Local Income Tax Withholding
   
    The federal income tax consequences of purchasing common stock under the
stock purchase plan are described below. Sometimes the sale of shares of common
stock bought through the stock purchase plan may produce compensation income to
an employee. In that case, the employee's employer may be required to withhold
federal, state, and local income tax with respect to the amount of compensation
income recognized by the employee, as though that amount was paid to the
employee by the employer as wages. The employer may satisfy this withholding
obligation by withholding the required amount from other amounts, such as other
compensation or wages, paid by the employer to the employee or by having CH2M
HILL withhold the required amount from any amount that CH2M HILL may owe the
employee upon a re-purchase of the shares of common stock.     
 
Federal Income Tax Consequences of Purchases of Common Stock Under the Stock
Purchase Plan
   
    The following paragraphs summarize the material federal income tax
consequences of participation in the stock purchase plan. This summary is
intended to be general and is not     
 
                                       45
<PAGE>
 
   
intended to address every federal income tax issue that may arise from
participation in the stock purchase plan. This summary does not address
foreign, state or local tax issues, which may be significant. Each participant
in the stock purchase plan should consider obtaining professional tax advice
with respect to the tax impact on that participant of participation in the
stock purchase plan.     
   
   Federal Income Tax Consequences for the Participant. The federal income tax
consequences of participation in the stock purchase plan depend in part on
whether the participant is participating in the portion of the stock purchase
plan that is intended to qualify as an employee stock purchase plan under
Section 423 of the Internal Revenue Code, or whether the participant is
participating in the portion of the stock purchase plan that is not intended
to qualify as an employee stock purchase plan under that Section of the
Internal Revenue Code.     
   
   With respect to most of the participating affiliates, the stock purchase
plan is intended to qualify as an employee stock purchase plan under Section
423 of the Internal Revenue Code. This means that, with respect to purchases
of common stock under the stock purchase plan by employees of those
affiliates:     
     
  . The participant will not recognize income for federal income tax purposes
    when the participant buys shares of common stock under the stock purchase
    plan.     
     
  . The participant will recognize ordinary income when the participant
    disposes of the common stock bought under the stock purchase plan. For
    this purpose, a participant is considered to dispose of common stock
    bought under the stock purchase plan when the participant transfers title
    to the common stock in any manner, including by sale, exchange, or gift,
    except that a participant is not considered to dispose of common stock
    bought under the stock purchase plan when the participant transfers the
    common stock to a spouse or into joint ownership if the participant is
    one of the joint owners.     
     
  . The amount of ordinary income recognized by the participant when the
    participant disposes of shares of common stock bought under the stock
    purchase plan depends on whether the participant held the shares for at
    least two years before disposing of them. If the participant held the
    shares for at least two years after the date on which the shares were
    bought for the participant's account under the stock purchase plan, the
    participant will recognize ordinary income when the shares are sold or
    otherwise disposed of. The amount of the ordinary income is equal to the
    smaller of:     
        
     (i) the amount by which the fair market value on the purchase date
         exceeded the amount paid for the shares, or     
        
     (ii) the amount by which the fair market value on the date of
          disposition exceeds the amount paid for the shares.     
      
   If the participant dies while owning shares of common stock bought under
   the stock purchase plan, ordinary income is recognized in the year of
   death in the amount described in the previous sentence.     
     
  . If the participant disposes of shares of common stock bought under the
    stock purchase plan before the two year holding period expires, the
    participant will recognize ordinary income at the time of the
    disposition. The amount of the ordinary income recognized by the
    participant will be the amount by which the fair market value of the
    shares on the purchase date exceeded the amount paid for the shares, even
    if the disposition is by gift or is at a loss.     
 
  . If the common stock is a capital asset in the hands of the participant,
    additional gain on the disposition of the shares of common stock, if any,
    will be short-term or long-term capital gain depending on whether the
    participant held the shares of common stock for 12 months or less, or for
    more than 12 months, respectively.
 
                                      46
<PAGE>
 
   
    In the cases discussed above, other than in the case of the participant's
death, the amount of ordinary income recognized by the participant is added to
the purchase price paid by the participant in order to determine the amount of
gain or loss from the disposition of the shares.     
   
    With respect to the portion of the stock purchase plan that is not intended
to be qualified as an employee stock purchase plan under Section 423 of the
Internal Revenue Code, a participant purchasing shares will recognize
compensation income at the time of the purchase of shares of common stock under
the stock purchase plan. The amount of this compensation income will be the
amount by which the fair market value of the shares on the purchase date
exceeds the amount of the purchase price paid by the participant.     
   
    Tax Consequences for CH2M HILL. CH2M HILL will not be entitled to a
deduction at any time with respect to shares sold under the portion of the
stock purchase plan that is intended to qualify as an employee stock purchase
plan under Section 423 of the Internal Revenue Code, if the participant buying
the shares does not dispose of the shares before the two-year holding period
expires. If the participant disposes of the shares prior to the expiration of
the two-year holding period, CH2M HILL is allowed a federal income tax
deduction that is equal to the amount of ordinary income recognized by the
participant.     
                
             Pre-Tax and After-Tax Deferred Compensation Plans     
   
    CH2M HILL will adopt, in connection with this offering, The CH2M HILL
Companies, Ltd. Pre-Tax Deferred Compensation Plan and the CH2M HILL Companies,
Ltd. After-Tax Deferred Compensation Plan, referred to in this description as
the deferred compensation plans. In connection with the deferred compensation
plans, CH2M HILL will establish the CH2M HILL Companies, Ltd. Pre-Tax Deferred
Compensation Trust and the CH2M HILL Companies, Ltd. After-Tax Deferred
Compensation Trust, referred to in this description as the deferred
compensation trusts. Neither deferred compensation plan is subject to ERISA.
       
    Two deferred compensation plans will be established to separately handle
pre-tax contributions in one plan and after-tax contributions in the other
plan. In effect, the pre-tax plan will hold contributions made through deferred
compensation and deferred bonus payments. CH2M HILL intends to administer
deferred compensation by participants in the pre-tax plan under the same terms
and conditions as the stock purchase plan. In contrast, the after-tax plan will
hold contributions made directly by employees eligible to participate. All of
the terms of the pre-tax plan and the after-tax plan are generally the same,
however the tax treatment distributions from the pre-tax plan and the after-tax
plan will be different.     
   
    Employees who are eligible to participate in the deferred compensation plan
may elect to invest by making after-tax contributions to the after-tax deferred
compensation plan. An employee who is eligible to participate in the pre-tax
deferred compensation plan may elect to defer a portion of his or her
compensation by entering into a deferred compensation agreement and by filing
an annual election to defer compensation in accordance with that agreement. In
addition, CH2M HILL or its affiliates may provide that bonuses to employees who
are eligible to participate in the pre-tax deferred compensation plan will be
deferred in accordance with the provisions of the plan.     
 
Administration of the Deferred Compensation Plans
   
    CH2M HILL will appoint a committee called the deferred compensation
committee that will administer the deferred compensation plans. The deferred
compensation committee will designate the affiliates of CH2M HILL whose
employees are eligible to participate in the deferred compensation plans.     
 
The Deferred Compensation Trusts
   
    The deferred compensation trusts are irrevocable trusts established by CH2M
HILL. The Trustee will be named at a later date. Copies of the agreements
establishing the deferred compensation trusts will be available from the
deferred compensation committee.     
 
Contributions to the Deferred Compensation Trusts
 
    Under the agreement between CH2M HILL and the Trustee, the Trustee will
receive and hold

common stock contributed to the deferred compensation trusts by CH2M HILL. When
an eligible employee elects under the pre-tax deferred compensation plan to
defer compensation, we will use the compensation that would have been paid to
the employee to purchase common stock, and will contribute that common stock to
the pre-tax deferred compensation trust. We may also contribute common stock to
the pre-tax deferred compensation trust as bonuses on behalf of eligible
employees.     
   
    When an eligible employee elects to make voluntary contributions to the
after-tax deferred compensation plan, we will use the cash contribution to
purchase common stock and contribute the common stock to the after-tax deferred
compensation trust.     
   
    Each contribution to the deferred compensation trusts will be allocated to
an account in the name of the employee on behalf of whom the contribution is
made. However, the employee will not have a direct ownership interest in the
shares of common stock held in the deferred compensation trusts.     
 
Nature of the Deferred Compensation Trusts
   
    All assets of the deferred compensation trusts will be held by the Trustee
for the benefit of the participants in the deferred compensation plans and for
the benefit of the general creditors of CH2M HILL in the event CH2M HILL
becomes insolvent. CH2M HILL is considered to be insolvent if it is unable to
pay its debts as they become due or if it is the subject of a bankruptcy
proceeding. If CH2M HILL becomes insolvent, the assets of the deferred
compensation trusts will be available to pay the debts of CH2M HILL. In that
case, a participant in the deferred compensation plans will not have any
priority rights with respect to the assets of the deferred compensation trusts
or with respect to any other assets of CH2M HILL. Rather, in the event of
insolvency, a participant in the deferred compensation plans will have only a
claim against CH2M HILL for the amount of compensation previously deferred and
the amount of any after-tax contribution made by the participant. This claim
will be treated like any other claim of a general unsecured creditor of CH2M
HILL. The assets of the deferred compensation trusts are not guaranteed or
insured by any party, including CH2M HILL.     
 
Voting of Common Stock Held in the Deferred Compensation Trusts
   
    Shares of common stock held in the deferred compensation trusts will be
voted by the Trustee, not by the participants in the deferred compensation
plans. The Trustee will vote the shares of common stock held in the deferred
compensation trusts in accordance with instructions given to the Trustee by the
deferred compensation committee.     
 
Dividends on Common Stock Held in the Deferred Compensation Trusts
   
    Cash dividends, if any, paid with respect to shares of common stock held in
the deferred compensation trusts will be returned to CH2M HILL and will not be
held in the deferred compensation trusts or made available to participants in
the deferred compensation plans. Other dividends, if any, paid with respect to
shares of common stock held in the deferred compensation trusts will be
credited to the account in the deferred compensation trusts in which the shares
of common stock are held.     
 
Distributions from the Deferred Compensation Trusts
   
    The common stock held in the deferred compensation trusts in the name of a
participant in the deferred compensation plans will be distributed to the
participant when a distribution event under the deferred compensation plans
occurs. The following events are distribution events under each deferred
compensation plan:     
 
  . The termination of the participant's affiliation with us, as defined in
    the Restated Bylaws.
     
  . The death of the participant. In this case, the distribution will be made
    to the beneficiary of the participant, as designated on a form signed by
    the participant and filed with the deferred compensation committee before
    the death of the participant. If the participant does not file a signed
    designation of beneficiary     
                                       48
<PAGE>
 
      
   with the deferred compensation committee before the participant's death,
   the distribution will be made to the participant's estate.     
     
  . A change in the participant's employment status that makes the
    participant ineligible to participate in the deferred compensation plans.
           
  . A request by the participant to exercise the participant's interest in
    the deferred compensation trusts. In this case a distribution will be
    made only if:     
        
     (i) the deferred compensation committee approves the participant's
         request, and     
        
     (ii) the common stock held in the deferred compensation trusts in the
          name of the participant can be sold in the internal market on the
          next trade date.     
     
  . The termination of the deferred compensation plans. This will occur no
    later than January 2, 2008. CH2M HILL, in its discretion, may terminate
    the deferred compensation plans before that date.     
     
  . The date specified by the participant at the date of election to
    participate in the deferred compensation plans.     
   
    Distributions from the deferred compensation trusts will be made in the
form of common stock. Shares of common stock distributed to a participant from
the deferred compensation trusts will be subject to the restrictions on
ownership of common stock set forth in our Restated Bylaws.     
 
Removal or Resignation of Trustee
   
    CH2M HILL may remove the Trustee of the deferred compensation trusts at any
time and for any reason, upon thirty days' notice to the Trustee. The Trustee
may resign at any time and for any reason, upon thirty days' notice to CH2M
HILL. If the Trustee is removed or resigns, CH2M HILL will appoint a new
Trustee.     
 
Amendment of the Deferred Compensation Trusts
   
    CH2M HILL and the Trustee may amend either deferred compensation trust at
any time by executing a written amendment to the corresponding deferred
compensation trust agreement.     
 
Federal Income Tax Consequences
   
    We have designed the deferred compensation trusts to be grantor trusts
under the federal income tax laws. This means that CH2M HILL's contribution of
common stock to the pre-tax deferred compensation trust should not cause a
participant in the pre-tax deferred compensation plan to recognize income at
the time of the contribution. Instead, the participant will recognize
compensation income when an amount is distributed or made available to the
participant from the pre-tax deferred compensation trust. The assets of both
deferred compensation trusts will be treated as assets of CH2M HILL for federal
income tax purposes.     
   
    In contrast, participants in the after-tax deferred compensation trust will
recognize compensation equal to the difference between the amount they
contributed and the value of cash or other property when it is distributed or
made available from the after-tax deferred compensation trust.     
   
    This treatment of participants in the deferred compensation plans for
federal income tax purposes is based on private letter rulings issued by the
Internal Revenue Service. The deferred compensation plans and the deferred
compensation trusts are not identical to the arrangements involved in those
private letter rulings, however, and a private letter ruling is binding on the
Internal Revenue Service only with respect to the specific taxpayer to whom the
private letter ruling is issued. We do not plan to seek a private letter ruling
on the federal income tax consequences of participation in the deferred
compensation plans. Therefore, while we believe that the federal income tax
consequences of participation in the deferred compensation plans should be as
described above, there is no definite assurance that this will in fact be the
case. If the federal income tax consequences of participation in the deferred
compensation plans are ultimately determined to be different from those
described above, participants in the deferred compensation plans may be liable
for additional income taxes, interest, and penalties for tax years during which
they participate in the deferred compensation plans.

    This description summarizes the material federal income tax consequences of
participation in the deferred compensation plans, but is not intended to be a
complete discussion of all federal income tax or other tax consequences of
participation in the deferred compensation plans. Each participant in the
deferred compensation plans should consider discussing the federal, state, and
local tax consequences of participation in the deferred compensation plans with
that participant's tax advisors.

    The current shareholders may sell up to an aggregate of 18,227,530 shares
of common stock. While we are registering all of the shares held by our current
shareholders, including all the shares currently held by our directors and
executive officers, we do not know whether they intend to sell any of their
common stock, but they may sell some, none or all of their shares.     
 
    We surveyed our significant shareholders informally on the number of shares
they actually expect to sell. These surveys indicate that current shareholders
intend to sell fewer than 10% of their shares in the next 12 months.
   
    The following table sets forth, as of May 1, 1999, the number of shares of
common stock owned by the current CH2M HILL shareholders, excluding shares

                          DESCRIPTION OF CAPITAL STOCK
 
                                    General
   
    The following is a summary of the material provisions of CH2M HILL's
Restated Articles of Incorporation and Restated Bylaws regarding CH2M HILL's
capital stock. You may find more detailed information by reading the Restated
Articles of Incorporation and the Restated Bylaws, copies of which are filed as
exhibits to the registration statement filed with the Securities and Exchange
Commission. The Restated Articles of Incorporation and Restated Bylaws will
take effect prior to the first trade date in the internal market if the Board
of Directors determines to give effect to the internal market at the Board's
November 1999 meeting.     
   
    CH2M HILL is authorized to issue 150,000,000 shares of capital stock, of
which 100,000,000 shares are common stock, par value $.01 per share, and
50,000,000 shares are Class A preferred stock, par value $.02 per share. As of
May 1, 1999, 1,806,829 shares of common stock and 1,112,369 shares of Class A
preferred stock were outstanding and held of record by approximately 1,000 key
employees and the employee benefit plan trusts.     
   
    As noted in the Prospectus Summary, the information in this prospectus has
been adjusted to reflect the conversion of each outstanding share of Class A
preferred stock into one share of common stock and a ten-for-one stock split of
the common stock, which will occur prior to the first trade date in the year
2000, if the Board of Directors determines to give effect to the internal
market at its November 1999 meeting. If the class A preferred stock had been
converted into common stock and the ten-for-one stock split had been completed
on May 1, 1999, there would have been 29,191,980 shares of common stock and no
Class A preferred stock outstanding on that date.     
 
                                  Common Stock
 
    General. Holders of common stock are entitled to one vote per share on all
matters submitted to the shareholders of CH2M HILL. Each share of common stock
is equal in respect of voting rights, liquidation rights and rights to
dividends and to distributions. Shareholders of CH2M HILL do not and will not
have any preferred or preemptive rights to subscribe for, purchase or receive
additional shares of any class of capital stock of CH2M HILL, or any securities
convertible into or exchangeable for such shares.
   
    Restrictions on Common Stock. All the shares of common stock presently
outstanding are, and all shares of common stock offered hereby will be, subject
to restrictions set forth in the Restated Bylaws:     
   
    1. Right of Repurchase upon Termination of Employment or Affiliation. All
shares of common stock are subject to CH2M HILL's right of repurchase upon the
termination of the shareholder's employment or affiliation with CH2M HILL. Such
right of repurchase will also be applicable to all shares of common stock which
such person has the right to acquire after his or her termination of employment
or affiliation pursuant to any of CH2M HILL's employee benefit plans or
pursuant to any option or other contractual right to acquire shares of common
stock which was outstanding at the date of such termination of employment or
affiliation. Such right of repurchase will not be applicable to shares of
common stock held by an employee benefit plan or any other retirement or
pension plan adopted by CH2M HILL or any of its subsidiaries which pursuant to
applicable law or by its terms does not provide for CH2M HILL's right to
repurchase shares issued thereunder upon termination of employment or
affiliation.     
   
    CH2M HILL's right of repurchase is exercised by mailing a written notice to
such holder within 60 days following termination of employment or affiliation.
If CH2M HILL repurchases the shares, the price will be the price per share:
    
  . in effect on the date of such termination of employment or affiliation,
    in the case of shares owned by the holder at that date and shares
    issuable to the holder after that date pursuant to any option or other
    contractual right to acquire shares of common stock which were
    outstanding at that date; or
 
  . in effect on the date such shares are distributed to the holder, in the
   case of shares distributable to the holder after his or her termination of
   employment or affiliation pursuant to any of CH2M HILL's employee benefit
   plans.
 
                                       58
<PAGE>
 
CH2M HILL will, in the event it exercises its right of repurchase upon
termination of employment or affiliation, pay for such shares in cash or
promissory notes.
 
    CH2M HILL and any holder of shares may agree to extend the time period of
CH2M HILL's right to repurchase such holder's shares or to alter the payment
terms.
 
    2. Right of First Refusal. If a holder of common stock desires to sell any
of his or her shares to a third party other than in the internal market, such
holder must first give notice to the Secretary of CH2M HILL including:
 
  . A signed statement indicating that such holder desires to sell his or her
    shares of common stock and that he or she has received a bona fide offer
    to purchase such shares
 
  . A statement signed by the intended purchaser containing:
 
   (i) the intended purchaser's full name, address and taxpayer
       identification number
 
   (ii) the number of shares to be purchased
 
   (iii) the price per share to be paid
 
   (iv) the other terms under which the purchase is intended to be made
 
   (v) a representation that the offer, under the terms specified, is bona
       fide; and
 
  . If the purchase price is payable in cash, in whole or in part, a copy of
    a certified check, cashier's check or money order payable to such holder
    from the purchaser in the amount of the purchase price to be paid in cash
 
    CH2M HILL then has the right, exercisable within 14 days, to purchase all
of the shares specified in the notice at the offer price and upon the same
terms as set forth in the notice. In the event CH2M HILL does not exercise such
right, the holder may sell the shares specified in the notice within 30 days
thereafter to the person specified in the notice at the price and upon the
terms and conditions set forth therein. The holder may not sell such shares to
any other person or at any different price or on any different terms without
first re-offering the shares to CH2M HILL.
 
    If circumstances occur which would permit CH2M HILL to exercise its right
of repurchase upon termination of employment or affiliation and its right of
first refusal, then CH2M HILL may, in its sole discretion, elect which of these
rights it will exercise.
 
    3. Other Transfers. Except for sales in the internal market or pursuant to
the repurchase right or right of first refusal procedure described above, no
holder of common stock may sell, assign, pledge, transfer or otherwise dispose
of or encumber any shares of common stock without the prior written approval of
CH2M HILL. Any attempt to do so without such prior approval will be null and
void. If any transfer of CH2M HILL's shares is not a sale by an employee,
director or consultant, or is by a person who acquired such shares other than
by purchase, directly or indirectly, from an employee, director or consultant,
CH2M HILL may condition its approval of such transfer upon the transferee's
agreement to hold such shares subject to CH2M HILL's right to repurchase such
shares upon the termination of employment or affiliation of the employee,
director or consultant.
 
    4. Ownership Limit. The Restated Bylaws provide that no person may own more
than 350,000 shares of common stock, excluding such person's beneficial
interest in common stock held indirectly by an employee benefit trust.
 
                            Class A Preferred Stock
 
    Holders of Class A preferred stock have no voting rights with respect to
matters submitted to the shareholders of CH2M HILL, except as required by law.
Upon the liquidation, dissolution, or winding up of CH2M HILL, whether
voluntary or involuntary, each holder of Class A preferred stock would be
entitled to be paid $.02 per share prior to any distributions to holders of
common stock. Rights granted to the holders of Class A preferred stock can only
be amended by a majority of the holders of common stock and a majority of the
holders of Class A preferred stock, each voting as a separate class. The Board
of Directors may elect at any time to convert each outstanding share of Class A
preferred stock into one share of common stock, without the prior consent of
the holders of either the Class A preferred stock or common stock.

                  Limitation of Liability and Indemnification
   
    Under the Oregon Business Corporation Act (the "Act"), a corporation may
provide for the limitation of liability of directors and indemnification of
directors and officers under some circumstances. CH2M HILL's Restated Articles
of Incorporation provide that directors are not personally liable to the
corporation or its shareholders for monetary damages for conduct as a director,
except for any act or omission for which the elimination of liability is not
permitted under the Act. Section 60.047(2)(d) of the Act sets forth the
following actions for which limitation of liability is not permitted,
including;     
     
  . any breach of a director's duty of loyalty to the corporation or its
    shareholders     
     
  . acts or omissions not in good faith or which involve intentional
    misconduct or a knowing violation of the law     
     
  . any unlawful distributions to shareholders; or     
     
  . any transaction from which the director received an improper or illegal
    personal benefit.     
   
    The Restated Bylaws allow CH2M HILL to indemnify any person who is or was a
party, or is threatened to be made a party, to any civil, administrative, or
criminal proceeding by reason of the fact that the person is or was a director
or officer of CH2M HILL or any of its subsidiaries, or is or was serving at
CH2M HILL's request as a director, officer, partner, agent, or employee of
another corporation or entity. The indemnification may include expenses,
including attorneys' fees, judgments, fines, and amounts paid in settlement,
actually and reasonably incurred by that person. Under the Section 60.391(1) of
the Act, indemnification is available if:     
     
  . the person acted in good faith     
     
  . the person reasonably believed the conduct was in the corporation's best
    interests, or at least was not opposed to its best interests; and     
     
  . in the case of a criminal proceeding, the person had no reasonable cause
    to believe the conduct was unlawful.     
 
   In addition, a person who is wholly successful, on the merits or otherwise,
in the defense of a proceeding in which the person was a party because the
person was a director, is entitled to indemnification for expenses actually and
reasonably incurred by the person in connection with the proceeding.
 
                     Commission Position on Indemnification
   
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act"), may be permitted to directors,
officers and controlling persons of CH2M HILL pursuant to provisions described
above, or otherwise, CH2M HILL has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities is asserted
by such director, officer or controlling person in connection with the
securities being registered, CH2M HILL will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.     
 
                    Anti-Takeover Provisions -- Legislation
 
    The Act provides that corporate directors, when evaluating a proposed
tender or exchange offer, merger, acquisition, or similar proposal, "may, in
determining what they believe to be in the best interests of the corporation,
give due consideration to the social, legal, and economic effects on employees,
clients, and suppliers of the corporation and on the communities and
geographical areas in which the corporation and its subsidiaries operate, the
economy of the state and nation, the long-term as well as short-term interests
of the corporation and its shareholders, including the possibility that these
interests may be best served by the continued independence of the corporation
and other relevant factors." Consequently, when evaluating a proposal for the
merger, consolidation, or sale of CH2M HILL, the Board of Directors may
consider the interests of groups or constituents other than CH2M HILL's
shareholders. Such consideration may cause the Board of Directors to reject an
acquisition proposal for reasons other than the price being offered.

    CH2M HILL is also subject to the Oregon Business Combination Act (the
"OBCA"). The OBCA generally provides that if a person (an "Interested
Shareholder") acquires voting stock of an Oregon corporation in a transaction
resulting in such person owning 15% or more of the total voting stock of such
corporation, then the corporation and the Interested Shareholder may not engage
in business combination transactions for three years following the date of such
acquisition. "Business combination transactions" include:     
     
  . a merger or plan of share exchange     
     
  . any sale, lease, mortgage, or other disposition of corporate assets where
    the assets have an aggregate market value of 10% or more of the aggregate
    market value of the corporation's assets or outstanding capital stock;
    and     
     
  . certain transactions that result in the issuance of capital stock of, or
    loans by, the corporation to the Interested Shareholder.     
 
These restrictions do not apply if:
     
  . the Interested Shareholder, as a result of the acquisition, owns at least
    85% of the outstanding voting stock of the corporation, excluding shares
    owned by directors who are also officers, and certain employee benefit
    plans     
 
  . prior to the completion of the acquisition the Board of Directors
    approves either the business combination transaction or the acquisition
     
  . after the completion of the acquisition the Board of Directors and the
    holders of at least two-thirds of the outstanding voting stock of the
    corporation, excluding shares owned by the Interested Shareholder,
    approve the business combination transaction     
 
    A corporation may provide in its Articles of Incorporation or bylaws that
the OBCA does not apply to its shares. CH2M HILL has not adopted such a
provision and does not presently plan to do so.
   
    In addition, the Oregon Control Share Act (the "OCSA") also applies to CH2M
HILL. The OCSA provides that a person or persons who acquire no less than 20%
of the voting shares of a corporation in a "control share acquisition," lose
the right to vote the shares unless such voting rights are restored through a
majority vote of the remaining shareholders. A person (the "Acquiring Person")
who acquires voting stock of an Oregon corporation in a transaction which
results in such Acquiring Person holding more than 20%, 33%, or 50% of the
total voting power of the corporation (a "Control Share Acquisition") cannot
vote such shares ("Control Shares") unless voting rights are accorded to the
Control Shares by the holders of a majority of the outstanding voting shares,
excluding such Control Shares and shares held by insiders. The vote is required
at the time an Acquiring Person's holdings exceed 20% of the total voting power
of a company, and again at the time the Acquiring Person's holdings exceed 33%
and 50%, respectively. "Acquiring Person" is broadly defined to include persons
acting as a group. The Acquiring Person may, but is not required to, submit to
CH2M HILL an "Acquiring Person Statement" setting forth information about the
Acquiring Person and its plans with respect to CH2M HILL. The Acquiring Person
Statement may also request that CH2M HILL call a special meeting of
shareholders to determine whether the Control Shares will be allowed to retain
voting rights. If the Acquiring Person does not request a special meeting of
shareholders, the issue of voting rights of Control Shares will be considered
at the next annual meeting or special meeting of shareholders that is held more
than 60 days after the date of the Control Share Acquisition. If the Acquiring
Person's Control Shares are accorded voting rights and represent a majority of
all voting power, shareholders who vote against restoring such voting rights
are entitled to the appraised "fair value" of their shares, which may not be
less than the highest price paid per share by the Acquiring Person for the
Control Shares.     
   
    The OCSA and the OBCA effectively encourage any potential acquirer to
negotiate with CH2M HILL's Board of Directors, and discourage potential
acquirers unwilling to comply with their provisions. A corporation may provide
in its Articles of Incorporation or bylaws that these laws shall not apply to
its shares. CH2M HILL has not adopted such provisions and does not currently
intend to do so. These laws may make CH2M     
 
                                       61

HILL less attractive for takeover, and shareholders, therefore, may not benefit
from a rise in the price of the common stock that could result from a takeover.
 
  Anti-Takeover Provisions -- Restated Articles of Incorporation and Restated
                                     Bylaws
 
    In addition to the laws discussed above, CH2M HILL's Restated Articles of
Incorporation and Restated Bylaws contain provisions that could make the
acquisition of CH2M HILL through a tender offer, proxy contest, or merger
difficult for a potential suitor opposed by the Board of Directors. These
provisions are:
 
  . The restriction on the sale of common stock outside of the internal
    market
 
  . CH2M HILL's right to repurchase shares of common stock upon the holder's
    termination of employment with CH2M HILL
     
  . CH2M HILL's right of first refusal on shares of common stock, except for
    shares sold in the internal market     
     
  . CH2M HILL's right to refuse to allow the transfer of shares of common
    stock to proposed transferees, except for shares sold in the internal
    market or pursuant to the right of first refusal     
     
  . The Restated Bylaws' prohibition on any shareholder owning more than
    350,000 shares of the common stock     
 
  . The existence of staggered terms for directors of CH2M HILL
 
                        SHARES ELIGIBLE FOR FUTURE SALE
   
    Upon completion of the offering, CH2M HILL will have outstanding up to
33,400,380 shares of common stock. Of these shares, the maximum 24,227,530
shares sold in the offering will be freely tradable in the internal market
without restriction or further registration under the Securities Act except for
any shares purchased by an "affiliate" of CH2M HILL, as defined in Rule 144
under the Securities Act. The remaining 9,172,850 shares of common stock are
held by our employee benefit plan trusts and may be sold in the internal market
either under Rule 144, subject to volume or holding period limitations, or
pursuant to a future registration statement declared effective under the
Securities Act.     
   
    As of May 1, 1999, 2,434,840 options to purchase common stock were
outstanding. A total of 8,000,000 shares of common stock are currently
available for future grants of options.

    The validity of the common stock offered hereby will be passed upon for
CH2M HILL by Holme Roberts & Owen LLP.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To CH2M HILL Companies, Ltd.:
 
    We have audited the accompanying consolidated balance sheets of CH2M HILL
Companies, Ltd. (an Oregon corporation) and subsidiaries as of December 31,
1997 and 1998 and the related consolidated statements of income, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of CH2M HILL's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We did not audit the financial statements of
CH2M HILL Industrial Design Corporation, which statements reflect total assets
and total revenues of 15 percent and 28 percent in 1996, 17 percent and 27
percent in 1997, and 8 percent and 20 percent in 1998, respectively, of the
related consolidated totals. Those statements were audited by other auditors
whose report has been furnished to us and our opinion, insofar as it relates to
the amounts included for this entity, is based solely on the report of the
other auditors.
 
    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 and the report of other
auditors provide a reasonable basis for our opinion.
 
    In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material
respects, the financial position of CH2M HILL Companies, Ltd. and subsidiaries
as of December 31, 1997 and 1998, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1998 in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                            (Dollars in thousands)
 
(1) Summary of Business and Significant Accounting Policies
 
   CH2M HILL Companies, Ltd. and its wholly owned subsidiaries is a
multinational infrastructure and environmental services firm. CH2M HILL's
predominant line of business is providing engineering services related to
water, environmental, transportation, infrastructure and management services.
CH2M HILL also provides facility design and construction management services
to the electronics, food processing and biopharmaceutical related industries
and provides utility system operations and maintenance services primarily for
water and wastewater treatment facilities.
 
   CH2M HILL provides the above services for clients in private industry,
federal government agencies, as well as state, municipal and local government
entities. A substantial portion of professional fees arises from projects that
are funded directly or indirectly by governmental entities.
 
Unaudited Pro Forma Information
       
   On November 6, 1998, the Board of Directors approved a new ownership
program for CH2M HILL and certain resolutions that were subsequently ratified
by a vote of the shareholders on December 18, 1998. Such resolutions included,
but were not limited to, the adoption of the 1999 Stock Option Plan and the
adoption of the Restated Bylaws and the Restated Articles of Incorporation
which provide for the:
 
  . termination of the existing Key Employee Policy and Agreement,
 
  . authorization to convert all outstanding Class A preferred stock into
    shares of common stock on a one-for-one basis,
 
  . increase in the authorized shares of common stock to 100,000,000, par
    value $.01 per share, and Class A preferred stock to 50,000,000, par
    value $.02 per share,
 
  . authorization of a ten-for-one stock split on CH2M HILL's common stock
    and Class A preferred stock, and,
 
  . imposition of certain restrictions on the stock including, but not
    limited to, the right but not the obligation to repurchase shares upon
    termination of employment or affiliation, the right of first refusal,
    and ownership limits.
 
   The effective date of the above resolutions will be decided at the
discretion of the Board of Directors based on its evaluation of the
effectiveness of the stock registration process, which includes an effective
registration statement on Form S-1 filed with the Securities and Exchange
Commission and the state Blue Sky commissions.
 
   Common and preferred stock amounts, equivalent share amounts and per share
amounts have been adjusted retroactively to give effect to the stock split.
The conversion of outstanding Class A preferred stock to common stock has been
reflected in the unaudited pro forma balance sheet at December 31, 1998.
   
   Preferred and common stock that is currently redeemable has been reflected
as temporary shareholders' equity in the balance sheets at December 31, 1997
and 1998. The pro forma unaudited balance sheet at December 31, 1998 reflects
the reclassification of the preferred and common stock from temporary
shareholders' equity to permanent shareholders' equity. Once CH2M HILL's new
ownership program is deemed effective, as discussed above, the mandatory
redemption feature of the stock will no longer apply.

all of its wholly owned subsidiaries after elimination of all intercompany
accounts and transactions. Investments in affiliates which are 50 percent or
less owned are reported using the equity method. Certain 1996 and 1997 amounts
have been reclassified to conform with the current year presentation.
 
Currency Translation
 
   All assets and liabilities of CH2M HILL's foreign subsidiaries are
translated into U.S. dollars at the period-end exchange rate. Revenues and
expenses are translated at the average exchange rate for the year. Translation
gains and losses are reflected in shareholders' equity as part of accumulated
other comprehensive loss. Deferred taxes are not provided on the translation
gains and losses. Gains and losses on foreign currency transactions are not
significant.
 
Accounting for Revenue
          
   CH2M HILL operates under a number of different types of contracts including
cost reimbursement contracts, time-and-materials contracts and fixed price
contracts. These contracts typically have specified limits on the amount that
may be earned by CH2M HILL. Revenue for these contracts is recognized
primarily on a percentage-of-completion basis by relating the actual cost of
work performed to date to the current estimated total cost of each contract.
Unbilled revenue represents the excess of contract revenue recognized over
billings to date. Billings in excess of revenues represent the excess of
amounts billed over revenue recognized. Losses on contracts in process are
recognized in their entirety when the loss becomes evident and the amount of
loss can be reasonably estimated.     
   
   The federal government accounted for 16.4% and 15.8% of our net receivables
in 1997 and 1998, respectively. Receivables are stated at net realizable
values, reflecting reserves of $2,977 and $8,201 in 1997 and 1998,
respectively.     
 
Cash and Cash Equivalents
   
   CH2M HILL maintains a cash management system which provides for cash in the
bank sufficient to pay checks as they are submitted for payment and invests
cash in excess of this amount in interest bearing short-term investments such
as certificates of deposit, commercial paper and repurchase agreements. These
investments are invested with original short-term maturities of less than
three months and are considered cash equivalents in the consolidated balance
sheets and statements of cash flows.

                             (Dollars in thousands)
 
Property, Plant and Equipment
 
    All additions, including betterments to existing facilities, are recorded
at cost. Maintenance and repairs are charged to expense as incurred. When
assets are retired or otherwise disposed of, the cost of the assets and the
related accumulated depreciation are removed from the accounts. Any gain or
loss on retirements is reflected in income in the year of disposition.
 
    Depreciation for owned property is based on the estimated useful lives of
the assets using both straight-line and accelerated methods for financial
statement purposes. Useful lives for buildings and land improvements range from
15 to 30 years with an average life of 25 years. Leasehold improvements are
depreciated over the remaining term of the associated lease. Useful lives on
other assets range from two to ten years with an average of approximately five
years.
 
Other Assets
 
    Other Assets includes capitalized software costs and goodwill which are
amortized on a straight-line basis over five to seven years. The historical
cost of these assets at December 31, 1997 and 1998 totaled $17,116 and $14,789,
respectively. The amortization reflected in the statements of income and the
statements of cash flows totaled $1,439 in 1996, $2,195 in 1997 and $2,778 in
1998.
   
Other Accrued Liabilities     
   
    Other accrued liabilities include amounts accrued for the payment of
various types of taxes, including income, property, sales and use, and value
added taxes. It also includes amounts accrued for professional liability
settlements that have not yet been paid and amounts accrued for general
business expenses.     
   
Other Long-Term Liabilities     
   
    Other long-term liabilities include amounts accrued for post-retirement
medical benefits, pension obligations, professional liabilities and deferred
compensation benefits.     
 
Fair Value of Financial Instruments
 
    The carrying amounts of cash and cash equivalents, accounts receivable,
accounts payable and accrued liabilities approximate fair value due to the
short-term maturities of these assets and liabilities. The interest rates on
CH2M HILL's bank borrowings are adjusted regularly to reflect current market
rates. Accordingly, the carrying amount of CH2M HILL's short-term and long-term
borrowings also approximate fair value. At December 31, 1997 and 1998, the fair
value of CH2M HILL's notes payable to former shareholders was $20,579 and
$19,237, respectively, based on a discount rate that is estimated using the
rates currently offered for debt with similar remaining maturities.
 
Pervasiveness 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 revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Asset Impairment
 
    CH2M HILL reviews its assets for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Assets which are held and used in operations would be impaired if
the undiscounted future cash flows related to the asset did not exceed the net
book value.
 
New Accounting Standards
 
    The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income". SFAS No.
130 requires that all changes in equity, other than transactions with owners,
be reported as comprehensive income in the financial statements. Other
comprehensive income items include foreign currency translation adjustments and
minimum pension liability adjustments. CH2M HILL has adopted SFAS No. 130
during fiscal 1998.
 
    SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," establishes standards for reporting information about operating
segments. It also establishes standards for enterprise-wide disclosures related
to geographic areas and major customers. CH2M HILL has adopted SFAS No. 131
during fiscal 1998.
 
    SFAS No. 132, "Employers Disclosure About Pensions and Other Postretirement
Benefits, an Amendment of FASB Statements No. 87, 88 and 106," revises
employers' disclosures about pension and other postretirement benefit plans. It
does not change the measurement or recognition of these plans. CH2M HILL has
adopted SFAS No. 132 during fiscal 1998.
 
    SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities," establishes fair value accounting and reporting standards for
derivative instruments and hedging activities. CH2M HILL will adopt SFAS No.
133 in the first quarter of fiscal 2000. CH2M HILL is currently assessing the
effect of adoption, if any, on its financial position, results of operations,
and cash flows.
   
    Statement of Position (SOP) 98-5, "Reporting on the Costs of Start-Up
Activities," requires costs of start-up activities, including organization
costs, to be expensed as incurred. CH2M HILL adopted SOP 98-5 effective January
1, 1999. Such adoption did not have an impact on earnings.     
       
(2) Segment Information
 
    CH2M HILL operates in three reportable segments that offer different
services to different customer bases. They are managed separately because each
business requires different business and marketing strategies. Environmental,
Energy, and Infrastructure (EE&I) includes management, consulting, design,
construction, procurement, and operations and maintenance services to the
environmental, nuclear, energy, systems, and transportation industries. Water
focuses on the planning, design and implementation of water supply systems and
wastewater treatment facilities as well as providing operations and maintenance
services to water and wastewater facility operators. Industrial provides
design, construction, specialized manufacturing support and sustained facility
services support to high-technology manufacturing companies, food and beverage
processing businesses, and fine chemical and pharmaceutical manufacturers.
 
    CH2M HILL evaluates performance based on several factors, of which the
primary financial measure is profit before tax. The accounting policies of the
segments are the same as those described in the summary of significant
accounting policies. Intersegment sales are accounted for at fair value as if
the sales were to third parties. Other includes the elimination of intersegment
sales and unallocable corporate expenses.

(3) Lines Of Credit
 
    CH2M HILL has an unsecured revolving credit agreement with a maximum
borrowing capacity of $85,000, which expires December 31, 1999. Interest
accrues on outstanding borrowings at variable rates, which as of December 31,
1997 and 1998, ranged from 6.0% to 8.5%, and from 5.4% to 7.8%, respectively,
based on maturity and a liabilities to earnings ratio. At December 31, 1997 and
1998, no amounts were outstanding under this line.
 
    The agreement requires CH2M HILL to maintain, among other restrictions,
prescribed liabilities to earnings, tangible net worth, working capital, and
fixed cost coverage ratios.
 
    The agreement allows CH2M HILL to issue letters of credit to back various
trade activities and insurance policies. Issued letters of credit are reserved
against the borrowing base of the line of credit. As of December 31, 1997 and
1998, there were $4,735 and $5,125 issued and outstanding letters of credit,
respectively.
 
    A subsidiary of CH2M HILL has a commitment for a line of credit for general
corporate purposes. The agreement is unsecured, and provides for aggregate
borrowings of $9,500, at an annual interest rate of prime (8.5% and 7.8% at
December 31, 1997 and 1998, respectively). No amounts were outstanding on the
line at December 31, 1997 and 1998.
 
(4) Notes Payable to Former Shareholders
 
    CH2M HILL issues interest-bearing notes to former shareholders for the
purchase price of stock redeemed by CH2M HILL. The total amount outstanding for
notes payable to former shareholders at December 31, 1997 and 1998 was $22,453
and $20,590, respectively. The interest on the notes is adjusted annually (on
the anniversary dates of the notes) based upon the U.S. Federal Reserve
Discount Rate on the first business day of each calendar year. At January 1,
1997 and 1998 the interest rate of the notes was 3.8%. The notes are unsecured,
and payable in varying annual installments through 2008.
 
    Future minimum principal payments on notes payable to former shareholders

   Total lease and rental expense charged to operations was $42,534, $40,561
and $41,475 during 1996, 1997 and 1998, respectively.
 
   Certain of CH2M HILL's operating leases contain provisions for a specific
rent free period. In accordance with generally accepted accounting principles,
CH2M HILL accrues rental expense during the rent free period based on total
expected rent payments to be made over the life of the related lease. The
excess of expense over actual cash payments to date is shown in the
accompanying balance sheets in other long-term liabilities. The cash payments
expected to exceed rental expense in the next year are included in other
accrued liabilities.
 
(7) Shareholders' Equity
 
   The bylaws and key employee agreements of CH2M HILL currently restrict
ownership of CH2M HILL's Class A preferred and common stock to active
employees and further provide that the following applies to such stock:
 
  . Upon death, withdrawal, legal incapacity, retirement or discharge, a
    shareholder's shares must be sold back to CH2M HILL.
 
  . Upon death, legal incapacity or retirement, the purchase price is
    determined by a formula calculated as of December 31 of each year, based
    on the net book value of CH2M HILL and a multiple of the average of the
    past five years' earnings.
 
  . The purchase price of stock from employees withdrawing to compete or who
    are discharged is the greater of the net book value of the shares or the
    price of the shares at acquisition by the employee.
 
  . The purchase price of stock returned to CH2M HILL generally becomes
    interest-bearing debt to be paid over a ten-year period. Subject to
    Board of Directors approval, the payout period can be shortened upon
    occurrence of certain criteria.

contingencies have been removed.
 
(8) Income Taxes
 
   CH2M HILL accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." SFAS No. 109 uses an asset and liability
approach that requires the recognition of deferred tax assets and liabilities
for the expected future tax effects of events that have been recognized in the
financial statements or tax returns. In estimating future tax consequences,
CH2M HILL generally considers all expected future events other than enactment
of changes in the tax laws or rates.
 
   Income (loss) from continuing operations before income taxes includes the
following:

    A valuation allowance is required to be established for those deferred tax
assets that it is more likely than not that they will not be realized based
upon certain estimated circumstances. The above valuation allowances relate to
foreign net operating losses of $7,500 and $9,000 for the years ended December
31, 1997 and 1998, respectively, which will require taxable income within the
applicable foreign subsidiary in order for the deferred tax asset to be
realized. The foreign net operating losses generally may be carried forward
indefinitely.
 
    At December 31, 1998, CH2M HILL has no material tax carryforwards.
 
    Undistributed earnings of CH2M HILL's foreign subsidiaries amounted to
approximately $4,200 at December 31, 1998. Those earnings are considered to be
indefinitely reinvested and accordingly, no provision for U.S. federal and
state income taxes or foreign withholding taxes has been made. Upon
distribution of those earnings, CH2M HILL would be subject to U.S. income taxes
(subject to a reduction for foreign tax credits) and withholding taxes payable
to the various foreign countries. Determination of the amount of unrecognized
deferred U.S. income tax liability is not practicable; however, unrecognized
foreign tax credit carryovers would be available to reduce some portion of the
U.S. tax liabilities.
 
(9) Earnings Per Share
 
    The computation of basic income per share is based on the weighted average
number of common and preferred shares outstanding during the year. The
outstanding preferred shares are included in the basic income per share
calculation since the preferred shares do not have any preferences over common
shares, other than in liquidation, and CH2M HILL anticipates conversion to
common shares on a one-for-one basis. Diluted income per share is based on the
weighted average number of common and preferred shares outstanding during the
year and, to the extent dilutive, common stock equivalents consisting of stock
options, stock awards subject to restrictions and stock appreciation rights. At
December 31, 1996, 1997 and 1998, CH2M HILL did not have dilutive securities
outstanding.

(10) Employee Incentive and Benefit Plans
 
Stock Based Compensation Plans
 
    The Financial Accounting Standards Board has issued SFAS No. 123,
"Accounting for Stock-Based Compensation." SFAS No. 123 requires that stock-
based compensation plans be accounted for based on the fair value based method
of accounting. CH2M HILL continues to measure compensation cost using the
intrinsic value based method of accounting prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," as permitted
by SFAS No. 123. CH2M HILL has three stock-based compensation plans as
described below. Had compensation cost been determined in accordance with SFAS
No. 123, CH2M HILL's net income and earnings per share for 1996, 1997 and 1998
would not have changed.
 
Incentive Plan
 
    CH2M HILL, at the discretion of the Board of Directors, provides stock
bonuses to certain designated key employees of CH2M HILL. Expenses under this
program amounted to $4,365, $4,784 and $5,550 in 1996, 1997 and 1998,
respectively.
 
Employee Stock Plan
 
    CH2M HILL has a profit sharing plan ("ESP") for all eligible employees and
has established an Employee Stock Plan and Trust to administer the ESP.
Contributions to the ESP are made to the Trust as determined by the Board of
Directors. Contributions to the ESP were $2,650, $2,804, and $3,513 in 1996,
1997 and 1998, respectively. The contributions are to be made primarily through
the issuance of Class A preferred stock.
 
Retirement and Tax-Deferred Savings Plan (the "401(k) Plan")
 
    CH2M HILL has a 40l(k) Plan that provides for company matching
contributions, which range from 0.5% to 2.0% of eligible employees' base pay.
Contributions for 1996, 1997 and 1998 were $1,493, $1,589 and $1,996,
respectively, and vest equally over a five year period, beginning with the
employees' second year of service. The contributions were made primarily
through the issuance of Class A preferred stock.
 
Defined Contribution Savings Plan
 
    CH2M HILL has a defined contribution plan that provides for contributions
generally equal to 1.5% of eligible employees' base pay. These contributions
vest equally over a five-year period, beginning with the employees' second year
of service. For the years ended December 31, 1996, 1997 and 1998, CH2M HILL
recorded $5,591, $6,045 and $5,084 in expense, respectively. Contributions are
made in cash.
 
(11) Other Employee Benefits
 
Pension and Other Postretirement Benefits
 
    CH2M HILL has several noncontributory defined benefit pension plans, of
which one remains active. Benefits are based on years of service and
compensation during the span of employment. Funding for these plans is provided
through contributions based on recommendations from the plans' independent

actuary. Plan assets consist primarily of common stock, corporate debt
instruments and U.S. government securities.
 
    CH2M HILL sponsors a medical benefit plan for retired employees of three
subsidiaries. The plan is contributory, with retiree premiums based on service
at retirement. The benefits contain limitations and a cap on future cost
increases. CH2M HILL continues to fund postretirement medical benefits on a
pay-as-you-go basis.

thereafter.

(12) Investments In Unconsolidated Affiliates
 
    CH2M HILL has investments in affiliated companies that are 50% or less
owned, which are accounted for under the equity method. These investments
consist primarily of a 50% ownership interest in Kaiser-Hill Company, LLC and
MK/IDC (PSI), which are domestic organizations, a 49% ownership interest in
CH2M Gore and Storrie Limited, a 50% ownership interest in CH2M HILL BECA, Ltd.

(13) CONTINGENCIES
 
General
   
    CH2M HILL is party to various legal actions arising in the normal course of
its business, some of which involve claims of substantial sums. Damages
assessed in connection with and the cost of defending any such actions could be
substantial. CH2M HILL's management believes that the levels of insurance
coverage are generally adequate to cover CH2M HILL's liabilities, if any, with
regard to such claims. CH2M HILL generally accrues amounts for retentions and
deductibles based on advice from legal counsel when it is probable that a loss
will be incurred and such loss is estimable. Gain contingencies or recoveries
are rare and are usually recorded when the cash is collected.     
   
    The amounts accrued at December 31, 1997 and 1998 related to probable
claims were $13,365 and $13,981, respectively, the majority of which was paid
out subsequent to December 31, 1998. Management believes that the amounts
accrued are adequate to cover the claims that have been identified by our legal
counsel as probable of loss. The amounts expensed for probable claims was
$3,900, $6,000 and $2,100 for 1996, 1997 and 1998, respectively. CH2M HILL
believes that should our loss exposure exceed the amount accrued, the final
settlement of these claims, individually or in the aggregate, will not have a
material adverse effect on our operations, cash flows or financial condition.
    
Guarantor
 
    CH2M HILL has an equity investment in an affiliate. The affiliate has a
facility which allows it to borrow up to $5,000. The facility is comprised of a
$3,000 line of credit and a $2,000 term loan. As of

                             (Dollars in thousands)
 
December 31, 1997, the outstanding balance on the term loan was $2,000, which
was paid off during 1998. No amounts were outstanding under the line of credit
as of December 31, 1997 and 1998. The facility is guaranteed by CH2M HILL.
 
    CH2M HILL has guaranteed a $6,000 credit facility between a subsidiary and
a joint venture partner. The facility is secured by assets of the joint venture
and is used for general project purposes. CH2M HILL has joint and several
liability with the joint partner for the full amount. At December 31, 1998,
$2,400 was outstanding on the credit facility which bears interest at varying
rates, as defined, and ranged from 6.6% to 7.8%.
 
Performance Bonds
 
    In the normal course of business, CH2M HILL purchases performance bonds to
comply with client mandated contractual obligations. At December 31, 1997 and
1998, the performance bonds purchased were $55,000.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Members of
Kaiser-Hill Company, LLC:
 
    We have audited the accompanying consolidated balance sheets of Kaiser-Hill
Company, LLC (a Colorado limited liability company) (the "Company") and
subsidiary as of December 31, 1998 and 1997, and the related consolidated
statements of income, members' equity and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Kaiser-Hill Company, LLC and subsidiary as of December 31, 1998 and 1997,
and the consolidated results of their operations and their cash flows for each
of the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. Organization
 
    Kaiser-Hill Company, LLC (the "Company") was formed on October 24, 1994.
The principal business of the Company is to procure, execute, deliver, and
perform under a five-year contract, commencing July 1, 1995, with the
Department of Energy ("DOE") to manage the programs and operate the DOE
facilities at Rocky Flats Environmental Technology Site ("RFETS") in Golden,
Colorado ("DOE contract"). The mission of the RFETS is directed toward cleanup,
deactivation, and preparation for decontamination and disposition of these DOE
facilities.
 
    The Company's contract will expire on June 30, 2000. The DOE is currently
considering its options which could include an extension of the Company's
contract or re-bid under a competitive process. While the Company believes that
its relationship with the DOE is good, the outcome will not be finalized until
after the release of these financial statements.
 
    At December 31, 1998, the Company employed 1,439 hourly workers and 321
salaried workers. Approximately 93% of the hourly employees are represented by
United Steel Works of America (the "Union") under a collective bargaining
agreement which expires on October 3, 2001.
 
    The Company maintains its cash accounts primarily with banks located in
Colorado, New York and North Carolina. The total cash balances are insured by
the FDIC up to $100,000 per bank. The Company had cash balances on deposit with
one Colorado bank in eight accounts at December 31, 1998 and 1997.
 
    The Company is a limited liability company owned equally by ICF Kaiser
Government Programs, Inc., a wholly owned subsidiary of ICF Kaiser
International, Inc. ("ICF Kaiser"), and CH2M Hill Constructors, Inc., an
indirect wholly owned subsidiary of CH2M Hill Companies, Ltd. ("CH2M Hill")
(collectively, the "Members"). Net profits and/or losses are allocated equally
to the Members, except for the 1994 bid and proposal costs which were allocated
to the Members based upon the actual amount incurred by such Members.
Distributions of Company earnings are allocated equally to the Members, except
for the 1996 distribution which adjusted the Members' equity balances for the
1994 bid and proposal costs.
 
2. Significant Accounting Policies
 
Principles of Consolidation
 
    The consolidated financial statements include the wholly owned subsidiary
of the Company, Kaiser-Hill Funding Company, LLC. All intercompany accounts and
transactions have been eliminated in the consolidated financial statements.
 
Revenue Recognition
 
    Revenue is recognized using the percentage of completion method whereby
revenue is accrued in an amount equal to cost plus management's best estimate
of base fee, performance based incentive fees and cost reduction proposal fees
to be received.
 
Statements of Cash Flows
 
    For purposes of the statements of cash flows, the Company considers cash in
checking and short-term investments with original maturities of three months or
less to be cash and cash equivalents.
 
Organization Costs and New Accounting Policy
 
    Organization costs are nonreimbursable costs, including legal, consulting,
financing and pre-transition costs incurred by the Company prior to the
commencement of the DOE contract, recorded at historical
 
                                      F-27

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)
 
cost and amortized on a straight line basis over five years. Amortization
expense was $787,000, $627,000 and $764,000 for the years ended December 31,
1998, 1997 and 1996, respectively.
 
    In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5 ("SOP 98-5"), Reporting on the Costs of
Start-Up Activities, which states that costs of start-up activities, including
organization costs, should be expensed as incurred. This statement is effective
for fiscal years beginning after December 15, 1998, and the initial adoption of
SOP 98-5 should be reported as a cumulative effect of a change in accounting
principle. Management believes that the Company's adoption of this new
accounting policy will result in costs of $1,004,000 to be written off in 1999.
 
Income Taxes
 
    The financial statements do not include a provision for income taxes
because the Company is treated as a partnership for income tax purposes and
does not incur federal or state income taxes. Instead, its earnings and losses
are included in the Members' separate income tax returns.
 
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 revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
3. Related Party Transactions
 
    In 1998 and 1997, the Members were subcontracted by the Company to perform
certain tasks under the DOE contract. The "Payable to Members" in the
accompanying balance sheets as of December 31, 1998 and 1997 consists of
$742,000 and $1,742,000, respectively, to ICF Kaiser and $-0- and $914,000,
respectively, to CH2M Hill for these subcontracted tasks. These payables are
non-interest bearing. The "Receivable from Member" in the accompanying balance
sheet as of December 31, 1998 consists of $396,000 due from CH2M Hill relating
to advance payment of general and administrative expenses, less operating
payables.
 
    In addition, costs incurred related to work performed by ICF Kaiser and
CH2M Hill, the majority of which are reimbursable and billed under the DOE
contract in 1998 were approximately $3,600,000 and $960,000, respectively, in
1997 were approximately $2,600,000 and $1,100,000, respectively, and in 1996
were approximately $1,300,000 and $1,000,000, respectively.
 
4. Contract Receivables and Receivables Purchase Facility Agreement
 
    Contract receivables as of December 31, 1998 and 1997 represent unbilled
receivables due under the DOE contract. Unbilled receivables result from
revenue that has been earned by the Company but not billed to the DOE as of the
end of the period. The unbilled receivables can be invoiced at contractually
defined intervals and milestones. Management anticipates that the unbilled
receivables will be billed and collected in less than one year.
 
    The Company's trade receivables result primarily from its long-term
contract with the DOE. As a consequence, management believes that credit risk
is minimal.

                    KAISER-HILL COMPANY, LLC AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)
 
 
    Through its wholly owned subsidiary, Kaiser-Hill Funding Company, LLC, the
Company has available at a financial institution a receivables purchase
facility agreement which provides temporary financing for the payment of the
Company's costs incurred under the DOE contract. This financing is utilized
throughout the year for periods of less than one month as, under the terms of
the DOE contract, the DOE must pay the Company's invoices within three days of
receipt. Contract receivables are collateral for the financed amount. The
maximum funding level for this agreement is $50,000,000, of which approximately
$50,000,000 and $27,000,000 were the unused portions at December 31, 1998 and
1997, respectively.
 
5. Contingencies
 
    The Company's reimbursable costs are subject to audit in the ordinary
course of business by various U.S. Government agencies. The Company is not
presently aware of any significant costs which have been, or may be, disallowed
by any of these agencies.
 
6. Employee Benefit Plans
 
    In accordance with the DOE contract, the Company sponsors several benefit
plans covering substantially all employees who meet length of service
requirements. These plans include the following defined benefit pension plans:
The Rocky Flats Multiple Employer Salaried Retirement Plan and the Kaiser-Hill
Retirement Plan for Hourly Production and Maintenance Employees. The Company
also sponsors the following defined contribution plans: Kaiser-Hill Company,
LLC Savings Plan for Hourly Employees, which includes no Company matching; and
Rocky Flats Multiple Employer Salaried Thrift Plan, which includes Company
matching. The Company contribution amounts for the Savings Plan/Thrift Plan
were approximately $413,000, $482,000 and $615,000 for 1998, 1997 and 1996,
respectively. No amounts were contributed to the Retirement Plans during 1998
and 1997 because the Plans were overfunded. In 1996, contributions of
$6,917,000 were made to the retirement plans.
 
    The Company administers these benefit plans with benefits equivalent to the
RFETS contractor benefit plans maintained by the contractor that preceded the
Company at RFETS. Under the DOE contract, the Company recognizes the cost of
benefit plans when paid, and such costs are reimbursed by the DOE. Any excess
pension plan assets or unfunded pension plan liability which may currently
exist or is remaining at the end of the DOE contract is the responsibility of
the DOE.

Item 14. Indemnification of Directors and Officers
 
    Under the Oregon Business Corporation Act (the "Act"), a corporation's
Articles of Incorporation may provide for the limitation of liability of
directors and indemnification of directors and officers under some
circumstances. In accordance with Oregon law, CH2M HILL's Restated Articles of
Incorporation provide that directors are not personally liable to the
corporation or its shareholders for monetary damages for conduct as a director,
except for any act or omission for which the elimination of liability is not
permitted under the Act. Section 60.047(2)(d) of the Act sets forth the
following actions for which limitation of liability is not permitted, including
(i) any breach of a director's duty of loyalty to the corporation or its
shareholders; (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law; (iii) any unlawful
distributions to shareholders; or (iv) any transaction from which the director
received an improper or illegal personal benefit.
 
    CH2M HILL's Restated Bylaws allow it to indemnify any person who is or was
a party, or is threatened to be made a party, to any civil, administrative, or
criminal proceeding by reason of the fact that the person is or was a director
or officer of CH2M HILL or any of its subsidiaries, or is or was serving at
CH2M HILL's request as a director, officer, partner, agent, or employee of
another corporation or entity. The indemnification may include expenses,
including attorneys' fees, judgments, fines, and amounts paid in settlement,
actually and reasonably incurred by that person. Under the Section 60.391(1) of
the Act, indemnification is available if (i) the person acted in good faith;
(ii) the person reasonably believed the conduct was in the corporation's best
interests, or at least was not opposed to its best interests; and (iii) in the
case of a criminal proceeding, the person had no reasonable cause to believe
the conduct was unlawful. In addition, a person who is wholly successful, on
the merits or otherwise, in the defense of a proceeding in which the person was
a party because the person was a director, is entitled to indemnification for
expenses actually and reasonably incurred by the person in connection with the
proceeding.
 
    CH2M HILL intends to purchase and pay the premium for insurance in respect
of claims against its directors and officers and in respect of losses for which
CH2M HILL may be required or permitted by law to indemnify such directors and
officers. The directors to be insured are the directors named herein and all
directors of CH2M HILL's subsidiaries. The officers to be insured are all
officers and assistant officers of CH2M HILL and its subsidiaries. CH2M HILL
does not expect to allocate or segregate the premium with regard to specific
subsidiaries or individual directors and officers.

Item 15. Recent Sales of Unregistered Securities
   
    As of December 31, 1997, CH2M HILL sold 783 shares of common stock to
Robert G. Card for $28,081.11 and 300 shares of common stock to Nancy R. Tuor
for $10,758.00. As of December 31, 1998, CH2M HILL sold 1,318 shares of common
stock to Robert G. Card for $50,373.96 and 184 shares of common stock to Nancy
R. Tuor for $7,032.48. Mr. Card and Ms. Tuor are former employees of CH2M HILL
who were key employee shareholders when employed by CH2M HILL and who currently
work for its affiliate, Kaiser-Hill Company, LLC. The issuance of such shares
was exempt from registration under Section 4(2) of the Securities Act of 1933,
as amended, as a transaction by the issuer not involving a public offering.

   (b) Financial Statement Schedules.
   
   All schedules for which provision is made in the applicable accounting
regulations of the Securities and Exchange Commission have been included in
the prospectus, are not required under the related instructions, are
inapplicable and therefore have been omitted, or the information required by
the applicable schedule is included in the notes to the consolidated financial
statements.     
 
Item 17. Undertakings
 
   The undersigned hereby undertakes:
 
   (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement;
 
    (i) To include any prospectus required by Section 10(a)(3) of the
  Securities Act of 1933, as amended;
 
    (ii) To reflect in the prospectus any facts or events arising after the
  effective date of the registration statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  registration statement; and
 
    (iii) To include any material information with respect to the plan of
  distribution not previously enclosed in the registration statement or any
  material change to such information in the registration statement;
 
   (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof;
 
   (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.
 
   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that any claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.
 
   For purposes of determining any liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
   
   For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:

Reference is made to the registration statement on Form S-1(the "Registration
Statement") filed with the Securities and Exchange Commission (the "Commission")
by CH2M Hill Companies, Ltd., an Oregon corporation (the "Company"), for the
purpose of registering 24,227,530 shares of Common Stock (the "Shares") under
the Securities Act of 1933.

As counsel for the Company, we have examined such documents and reviewed such
questions of law as we have considered necessary or appropriate for the purpose
of this opinion. Based on the foregoing, we are of the opinion that the Shares,
when sold and delivered by the Company, as described in the Registration

We consent to the filing of this opinion with the Commission as an exhibit to
the Registration Statement and with the securities law administrators of each
state in which registration or qualification of the Shares is sought.

We do not express an opinion on any matters other than those expressly set forth
in this letter.

Very truly yours,

         Re: CH2M HILL Retirement and Tax-Deferred Savings Plan

Members of the Board:

         On April 14, 1997, the Internal Revenue Service issued a favorable
determination letter confirming that the CH2M HILL Retirement and Tax-Deferred
Savings Plan (the "Plan") was qualified under Section 401(a) of the Internal
Revenue Code of 1986, as amended. A copy of that letter is attached. Since the
issuance of that favorable determination letter, the Plan has been amended. CH2M
HILL Companies, Ltd. (the "Company") intends to amend and restate the Plan
during the current year. The Company intends to file a timely application for a
determination letter from the Internal Revenue Service with respect to the
amended and restated Plan and to make any technical changes in the Plan required
by the Internal Revenue Service as a prerequisite to the issuance of a favorable
determination letter with respect to the amended and restated Plan. Based on
these facts and our knowledge of the Plan, we believe that the Internal Revenue
Service will issue a favorable determination letter confirming that the amended
and restated Plan remains qualified under Section 401(a) of the Internal Revenue
Code of 1986, as amended.

         We consent to the filing of this opinion with the Securities and 
Exchange Commission as an exhibit to the Company's Registration Statement No. 
333-74427 and with the securities law administrators of each state in which 
registration or qualification of the securities offered pursuant to said 
Registration Statement is sought.


                                             Sincerely,

Dear Applicant:

     We have made a favorable determination on your plan, identified above, 
based on the information supplied. Please keep this letter in your permanent 
records.

     Continued qualification of the plan under its present form will depend on 
its effect in operation. (See section 1.401-1(b)(3) of the Income Tax 
Regulations.) We will review the status of the plan in operation periodically. 

     The enclosed document explains the significance of this favorable 
determination letter, points out some events that may affect the qualified 
status of your employee retirement plan, and provides information on the 
reporting requirements for the plan. It also describes some events that 
automatically nullify it. It is very important that you read the publication. 

     This letter relates only to the status of your plan under the Internal 
Revenue Code. It is not a determination regarding the effect of other federal or

required by the Tax Reform Act of 1986 except as otherwise specified in this 
letter.

     This plan satisfies the nondiscriminatory current availability requirements
of section 1.601(a)(4) -4(b) of the regulations with respect to those benefits, 
rights and features that are currently available to all employees in the plan's 
coverage group. For this purpose, the plan's coverage group consists of those 
employees treated as currently benefitting for purposes of demonstrating that 
the plan satisfies the minimum coverage requirements of

respect to whether the plan satisfies the qualification requirements as amended

                               SERVICES AGREEMENT

         This is a Services Agreement ("Agreement") between Buck Investment
Services, Inc., a Delaware corporation with offices at 500 Plaza Drive,
Secaucus, New Jersey 07096 ("BIS"), and CH2M HILL Companies, Ltd., an Oregon
corporation with offices at 6060 South Willow Drive, Greenwood Village, Colorado
80111 ("CH2M"), dated to be effective as of March 15, 1999.

         1. Scope of Agreement. This Agreement sets forth the terms and
conditions under which BIS will assist with the implementation of, and serve as
broker and transfer agent with respect to, CH2M's internal market as further
outlined in Exhibit A (the "Services").

         2. Term. The term of this Agreement will begin March 15, 1999, and will
end when terminated in accordance with the provisions hereof. BIS acknowledges
the unique nature of the services it is providing under this Agreement and the
difficulty CH2M would have in replacing BIS without ample notice. Accordingly,
BIS agrees that so long as CH2M is not in default or breach of any of its
obligations hereunder, BIS may terminate this Agreement only upon two- years'
written notice of such termination to CH2M. Notwithstanding the foregoing, BIS
may terminate this Agreement upon thirty (30) days prior written notice thereof
to CH2M in the event of a breach or default by CH2M of any of its material
obligations hereunder which shall include, without limitation, any failure or
refusal to pay any amount payable to BIS pursuant hereto as and when due
subject, however, to the provisions of Section 3(c) hereof.

         Subject to the provisions of Section 3(a)(iv) hereof relating to
Termination Fees, CH2M may terminate this Agreement at the end of any calendar
quarter upon 30-days' written notice of such termination to BIS.

         3. Fees and Expenses. (a) Fees. (i) Except where CH2M and BIS agree to
the contrary for particular projects or services, CH2M will pay BIS the fees
prescribed in Exhibit B.

               (ii)  Any services provided by BIS at the request of CH2M which
are in addition to the Services contemplated by Section 1 above (or any
functional specifications developed pursuant thereto), shall be provided on such
terms as may be mutually agreed upon by BIS and CH2M. If no such terms are
specified, however, such services will be provided BIS's then-current time and
computer charges, with reasonable and necessary out-of-pocket expenses
reimbursed at cost in accordance with Section 3(b) below (all of which shall be
in addition to the fees prescribed in Exhibit B or otherwise hereunder).

               (iii) For the avoidance of doubt, any services required to be
provided by BIS as a result or consequence of any equity security constituting a
"Penny Stock" as defined under the Securities Exchange Act of 1934 or any
regulation promulgated pursuant thereto which services would not be required if
such security did not constitute a "Penny Stock" will be in addition to those
contemplated in Section 1 above and will be provided by BIS, to the extent
practicable, at its then-current time and computer charges, with reasonable and
necessary out-of-pocket expenses reimbursed at cost in accordance with the
provisions of (b) below.
<PAGE>
 
               (iv) In the event that CH2M elects to terminate this Agreement at
any time prior to December 31, 1999 in accordance with the provisions of Section
2 above or, in the event that this Agreement is terminated by BIS as a result of
the failure or refusal of CH2M to pay any amount payable to BIS hereunder as and
when due and, in any such event so long as BIS has not failed to perform any
obligation required of it pursuant hereto, on or before the effective date of
any such termination, CH2M shall pay to BIS a termination fee in an amount equal
to the difference between (a) $125,000, and (b) the aggregate of all fees paid
by CH2M pursuant to this Agreement prior to the effective date of such
termination.

          (b)  Expenses. In addition to the fees payable under this section,
CH2M will reimburse BIS for its reasonable and customary out-of-pocket expenses,
including travel, printing, postage, and dedicated telephone and computer lines,
incurred in connection with the performance of Services under this Agreement.

          (c)  Payment. Subject to the payment schedule provided in Exhibit B
and except for any termination payment required pursuant to Section 3(a)(iv)
above which shall be payable on demand, at the end of each month during the term
of this Agreement, BIS will send CH2M an invoice indicating the fees and any
expenses then payable under this Agreement in connection with the provision of
the Services. CH2M will pay BIS the fees and expenses shown on the invoice, or
pay any undisputed fees and expenses shown on the invoice and notify BIS in
writing of any questions or disputes regarding the invoice, within 30 days of
receiving the invoice. All amounts which are not disputed in good faith and in
writing as provided above, and which are not paid within 30 days of receipt of
the invoice will bear interest at the rate of 1 percent per month. All invoices
will be rendered and payments will be made in U.S. dollars in the United States.

     4.   Confidentiality. (a) General. CH2M and BIS may from time to time
communicate to the other proprietary, confidential or other information to
enable the other to perform its responsibilities under this Agreement. CH2M and
BIS will treat all such information as confidential, and will take all
reasonable precautions not to disclose any such information to any person
outside their respective organizations without the consent of the other,
including, but not limited to, all precautions taken by CH2M or BIS, as the case
may be, to safeguard the confidentiality of its own proprietary and confidential
business information. CH2M and BIS will also limit the use and distribution of
such information within their respective organizations to the extent necessary
and appropriate to perform the Services.

          (b)  Exceptions. The foregoing obligation of confidentiality will not
apply to information which is (i) in the public domain or comes into the public
domain through no fault of CH2M or BIS; (ii) known to CH2M or BIS, as the case
may be, before disclosure or subsequently independently developed by CH2M or BIS
without use of or reference to such information; (iii) disclosed to CH2M or BIS
by a third person under no obligation of confidentiality to CH2M or BIS; or (iv)
required by any governmental authority to ensure compliance with laws, rules or
regulations, in which case CH2M or BIS, as the case may be, will provide advance
notice to the other of the need for the disclosure, and will not disclose absent

                                       2
<PAGE>
 
consent from the other, except to the extent required by law, legal process or
regulatory authority having jurisdiction over CH2M or BIS.

         5.  Independent Contractor Relationship. The relationship of BIS to
CH2M is that of an independent contractor, and nothing in this Agreement creates
an agency, master-servant, trust, fiduciary, or any other relationship between
BIS (or any of its officers, directors, or employees) and CH2M (or any of its
officers, directors or employees).

         6.  Arbitration. Any controversy or claim arising out of or relating to
this Agreement, or the breech thereof, will be settled by binding arbitration
conducted by the National Association of Securities Dealers, Inc. ("NASD") in
Denver, Colorado, in accordance with the Arbitration Rules of the NASD and
judgment upon the award rendered by the arbitrators may be entered in any court
of competent jurisdiction. It is hereby agreed and acknowledged that either
party may seek, and such arbitrators may grant, injunctive relief.

         7.  Complete Agreement; Governing Law. This Agreement, including
Exhibits A and B hereto and any function specifications developed (and mutually
agreed upon) pursuant hereto contain the entire agreement of the parties and
there are no promises, understandings, or agreements of any kind pertaining to
this Agreement other than stated herein. This Agreement will be construed and
enforced in accordance with the laws of the State of New York without regard to
the legislative or judicial conflicts of law rules of any state.

         8.  Assignment. Neither party may assign its rights or delegate its
duties under this Agreement without the prior written consent of the other party
hereto.

         9.  Limitation of Liability. Subject to the selection of remedies set
forth in Section 11 of this Agreement, BIS will be responsible to CH2M only for
BIS's (a) breach of a representation or warranty set forth in Section 10 of this
Agreement or other material failure to perform its obligations hereunder or, (b)
negligence in the performance of its obligations hereunder; or (c) wilful
misconduct on the part of BIS. Notwithstanding the foregoing, BIS will not be
responsible or liable to CH2M or any employee of CH2M for BIS's (i) failure to
perform any services other than those specifically agreed to pursuant to this
Agreement; (ii) actions or failures to act based on instructions or directions
from CH2M or with the concurrence of CH2M, or (iii) failure to provide the
Services listed on Exhibit A or outlined in any functional specifications
developed pursuant hereto or perform any other obligation pursuant hereto
primarily because of (a) any error or omission in data, documents, or
information provided by or on behalf of CH2M or (b) any failure on the part of
CH2M to provide any service or product required to be provided by it pursuant to
Exhibit A and upon which the Services to be provided by BIS are directly or
indirectly dependent.

CH2M payroll extracts provided by CH2M after each semi-monthly payroll date. BIS
will provide CH2M such reports as it may reasonably request from time to time.
BIS will calculate expense associated with such plan under Financial Accounting
Standard 123 using assumptions and methodology approved by CH2M. BIS will assist

plan and will render advice to CH2M's communications team, but BIS will not be
responsible for developing other communications materials.

of CH2M who are identified by CH2M as subject to section 16(b) of the Securities

                               SCHEDULE OF FEES


CH2M will pay BIS the following fees and expenses:

Implementation (Set-Up) Fees in 1999

In consideration for, and subject to the implementation (Set-Up) by BIS of the
Internal Market, CH2M will pay BIS implementation fees during 1999 of $125,000
($31,250 upon execution of this Agreement; $31,250 on June 30, 1999; $31,250 on
September 30, 1999; and $31,250 on December 31, 1999; and

Administrative Service Fees in 2000

Beginning in 2000, CH2M will pay BIS a quarterly fee of $55,000 (offset by any
brokerage commissions which BIS receives for Internal Market brokerage
transactions). In the event that such brokerage commissions exceed $55,000, BIS
will use the excess to defray the (non-BIS- related) costs of CH2M maintaining
the Internal Market.

For each year from and after 2000 during the term of this Agreement (including
any year comprising any portion of the two-year notice of termination required
to be given by BIS pursuant to Section 2 hereof) CH2M will pay BIS such fees as
may be mutually agreed or, in the absence of such Agreement, fees in an amount
equal to 110% of the fees payable by CH2M for and in respect of the immediately
preceding year. The failure of the parties to reach an agreement as to fees
payable hereunder on or before March 15 of any year during the term hereof for
which such fees are to be determined shall, without further action by either
party, be deemed to constitute a notice of termination hereof by BIS which
notice shall be deemed to have been so give effective on January 1 of such year.

                         RESTATED KEY EMPLOYEE POLICY
                                      OF
                           CH2M HILL COMPANIES, LTD.


Section 1 - Purpose.

The purpose of this Restated Key Employee Policy is to outline the policies of
CH2M HILL Companies, Ltd. (hereinafter referred to as the Corporation) in regard
to stock ownership, key employee status, incentive bonuses, retirement
provisions and procedures for stock acquisitions and dispositions by key
employees. Neither this Policy nor the Key Employee Agreement shall in any way
be construed as an employment agreement.


Section 2 - Definitions.

For the purposes of this Restated Key Employee Policy:

a.   A "key employee" is an employee of the Corporation or an affiliate of the
     Corporation who is actively contributing to the success of the Corporation
     and who has been proposed and approved as a key employee in accordance with
     Section 3.b. below. Key employees may also be stockholders of the
     Corporation.

b.   "Key Employee Voting Units." Key employees shall be entitled to vote on
     matters affecting this Restated Key Employee Policy. Such entitlement shall
     be based on one voting unit for each share of Common Stock or Class A
     Preferred Stock owned by the key employee and for each Voting Equivalent
     owned, as adjusted for any stock splits, stock dividends, and the like.

c.   "Voting Equivalent." The Board of Directors may, in its discretion,
     recognize stock or other participation in the Corporation or its affiliate
     as the equivalent of stock in the Corporation for purposes of voting as a
     key employee. The Board of Directors shall define as a "Voting Equivalent"
     the amount of such stock or participation that will be equal to one key
     employee voting unit.

d.   A "departing" key employee is one who separates from the Corporation and
     its affiliates and is not a discharged or withdrawing key employee.

e.   A "discharged" key employee is one who is removed from employ of the
     Corporation and its affiliates because of failure to perform according to
     requisite standards, as decided in specific circumstances by the Board of
     Directors.

f.   A "withdrawing" key employee is one who voluntarily separates from employ
     of the Corporation and its affiliates.

                                                                          PAGE 1
<PAGE>
 
g.   The words "separate" or "separation" shall mean the cessation of
     employee-employer relationships between a key employee and the Corporation
     or its affiliates, whether by retirement, discharge, dismissal, withdrawal,
     death, insanity, legal incapacity, or for any other reason.


Section 3 - Stock Ownership and Key Employees.

a. Purpose and Policy.

The purpose of this Section is to define the policy of the Corporation to
    maintain ownership of its stock by compatible persons actively contributing
    to its success. This policy is based on the belief of the original
    stockholders that stock ownership by competent, loyal, contributing
    employees will be of continuing benefit to the Corporation. Ownership of
    substantially all of the outstanding stock of the Corporation shall be
    restricted to employees or the Employee Stock Ownership Trust (ESOT)
    described in Article 8 of the Restated Bylaws. To assure this result, Common
    and Class A Preferred Stock in the Corporation may be held only by:

    -   Employees of the Corporation or an affiliate of the Corporation.
    -   The ESOT.
    -   Persons who received stock by distributions from the ESOT before 
        January 1, 1983, or transferees of such persons

b. Eligibility for Key Employee Status and Rights and Benefits Thereunder.

(1)  Designation of Key Employees.

     A person shall be a key employee of the Corporation when designated as such
     by a majority vote of the Board of Directors and the further approval of a
     majority of the key employee voting units entitled to vote and represented
     at the meeting. An employee of an affiliate of the Corporation may become a
     key employee following approval by the affiliate's Board of Directors,
     subject, however, to ratification by the Corporation's Board of Directors
     and a majority of the key employee voting units entitled to vote and
     represented at the meeting. Rights, benefits and responsibilities of key
     employees will be as hereinafter provided.

(2)  Key Employees in Affiliates.

     In the event of a transfer of full-time employment from one entity to
     another, a key employee in any CH2M HILL Companies, Ltd. affiliate shall
     automatically remain a key employee in the entity to which the key employee
     is permanently assigned. Rights, benefits and responsibilities of said
     transferred key employee shall be essentially the same.

                                                                          PAGE 2
<PAGE>
 
c. Redemption of Stock.

Upon a key employee's separation or in the event a key employee files a petition
   for bankruptcy or is the subject of an involuntary bankruptcy proceeding, or
   the key employee's stock of this Corporation is attached, garnished or levied
   upon; such key employee, the key employee's estate, or legal representative,
   or trustee holding said stock must sell and deliver forthwith the stock to
   the Corporation and the Corporation must purchase said stock on the following
   basis:

(1)  Market Value Components.

     The market value of a share of Common Stock or Class A Preferred Stock
     shall be the sum of the following two components divided by the number of
     shares of Common and Class A Preferred Stock then outstanding (as adjusted
     for any stock splits, stock dividends, and the like) and the number of
     Voting Equivalents deemed appropriate by the Board of Directors:

          a)   Present Book Value Component.

               The present book value component shall be the total book value of
               the Corporation as of the end of the last preceding tax year, as
               audited. Nonrecurring or abnormal transactions may be excluded
               from the above definition of the present book value component at
               the discretion of the Board of Directors.

          b)   Present Going Concern Value Component.

               The present going concern value component shall be 1.5 times the
               previous five fiscal year average of "net income," which is
               defined as the net income on an accrual basis according to the
               books of the Corporation, as audited, after the deduction of all
               costs but before the deduction of bonuses and income taxes. Said
               net income is to generally include that of Corporation
               subsidiaries in proportion to the respective ownership by the
               Corporation therein (e.g., if the Corporation owns 51 percent of
               a subsidiary, 51 percent of that subsidiary's net income as
               defined herein would be included in this computation).
               Nonrecurring or abnormal transactions may be excluded from the
               above definition of net income at the discretion of the Board of
               Directors.

          c)   Computation Approval.

           The computation of the above two components shall be made annually
               and approved by the Board of Directors.

          d).  Redemption Components.

                                                                          PAGE 3
<PAGE>
 
               The components to be used for calculating the redemption value
               may be modified in accordance with Subsection d. of this Section.

(2)  Nondelivery.

     In the event stock certificates are not delivered to the Corporation by the
     key employee at the time of separation, transfer of subject stock may be
     made at the discretion of the Board of Directors to the Corporation on the
     stock transfer books. At the same time, the Corporation shall issue
     appropriate promissory note(s) to the key employee, and the records for
     stock certificates transferred in this manner shall be changed to show
     cancellation of the subject stock.

(3)  Source of Funds for Stock Repurchase.

     Funds for repurchase shall be the corporate income, accumulated income, and
     such portions of surplus, earned or paid in, and capital, as may be
     permitted by statute.

(4)  Method of Payment.

     As of the date of separation, the key employee, the key employee's estate,
     or legal representative, shall deliver all stock certificates to the
     Corporation. In exchange for such stock, withdrawing key employees shall
     receive promissory notes in accordance with Subsection d. (4) of this
     Section. All other key employees separating from the Corporation shall
     receive a single promissory note.

     Terms of all notes will provide that on the date the note is issued (the
     Note Date) and each succeeding anniversary of the Note Date until totally
     paid, 1/10 of the original principal will be paid to the key employee, the
     key employee's estate, or legal representative, and that the Corporation
     has the right to prepay all or any portion of the notes in accordance with
     the applicable provisions of the Key Employee Policy or Board of Directors
     policy at the time of prepayment. The Note Date will be within 75 days
     after the meeting of the Board of Directors that acts on the separation of
     the key employee. Any promissory notes issued for stock will bear interest,
     to be paid annually, at the rate of 3/4 of the U.S. Federal Reserve
     discount rate in effect on January 1 of the calendar year in which the
     notes are issued, to be adjusted on each succeeding January 1 to 3/4 of the
     U.S. Federal Reserve discount rate then in effect; provided, however, that
     if a payee dies, the next payment shall be due on the last day of the
     eighth full month after date of death, and subsequent payments shall be due
     annually thereafter, i.e., on the anniversary of the day on which the
     payment was made following death.

     The Board of Directors, in its sole discretion, may make the decision to
     pay the redemption value in a cash lump sum at the time of separation or
     thereafter.

                                                                          PAGE 4
<PAGE>
 
     Annual payment for redemption of stock, except for key employees who are
     retired, totally disabled or dismissed and their heirs or legal
     representatives may be limited at the sole discretion of the Board of
     Directors to 2.5 percent of the net income as defined in Subsection
     c.(1)(b) of this Section. Postponed sums shall be a debt of the Corporation
     and shall bear interest at the rate of 3/4 of the U.S. Federal Reserve
     discount rate in effect on January 1 of the calendar year in which
     postponement occurs, interest to be paid annually. In event the sums
     available are inadequate, the total sums available shall be prorated among
     the selling key employees. Deferred payments shall have priority the
     following year over payments becoming due in said following year.

     Subject to any limitations of this paragraph or any other provision of this
     Restated Key Employee Policy, the Corporation may accelerate payment of
     principal in accordance with such policies as the Board of Directors may
     from time to time establish.

d.   Provisions of Redemption.

(1)  Determination of Redemption Value.

   Stock to be redeemed by the Corporation under provisions of Section 3.c.
     above, shall be based on the applicable redemption value components
     determined for the last preceding tax year, as audited.

   The redemption value of such stock shall be the current market value as 
     defined in Section 3.c.(1) above. However, the redemption value for stock
     of a discharged key employee or a key employee withdrawing to compete shall
     be only the present book value component of the stock or the market value
     of each specific share of stock at the time of acquisition by the key
     employee, as adjusted for any stock splits, stock dividends, and the like,
     whichever is greater, except that in no event shall the redemption value be
     more than the current market value of the stock.

(2)  Payment.

Payment for stock redeemed by the Corporation shall be according to the
     provisions of Section 3.c.(3) and (4) above.

In the event a separated key employee dies prior to receiving all payments, the
     remaining payments shall be made to the estate or legal representative.

(3)  Appointment of Legal Representative.

If no legal representative has been appointed for a legally incapacitated
     key employee, the Corporation may seek the appointment of such legal
     representative.

(4)  Withdrawing Key Employee.

                                                                          PAGE 5
<PAGE>
 
A withdrawing key employee shall be issued two promissory notes in exchange for
     stock, except that a withdrawing key employee who is judged by the Board of
     Directors to compete shall be issued only one promissory note, i.e., "A"
     following. One note ("A") shall be issued for an amount equal to the
     present book value component of the stock held or the market value of each
     specific share of stock at the times of acquisition by the key employee, as
     adjusted for any stock splits, stock dividends, and the like, whichever is
     greater; but in no event shall the amount be greater than the current
     market value; the other note ("B") shall be issued for an amount equal to
     the current market value of all shares held less the amount of note "A."

Payments shall be made as stated above in Subsection 3.c.(4) as long as the
     withdrawing key employee does not compete with the Corporation or an
     affiliate. If the withdrawing key employee competes, note "B" shall be
     canceled and no further payment shall be made for this component of the
     subject stock. Any amounts previously paid on note "B" shall be deducted
     from subsequent payments on note "A"; any amounts paid the key employee on
     note "B" which are not recoverable by remaining payments on note "A" shall
     immediately become due and payable by the withdrawing key employee to the
     Corporation.

     In determining whether or not a withdrawing key employee engages in a
     competitive enterprise, the judgment of the Board of Directors shall be
     conclusive.

e. General Conditions Applicable to All Key Employees Whose Stock is Being
   Redeemed.

(1)  Specific Performance.

     The Corporation may seek specific performance of all or any parts of its
     rights and the obligations of its key employees pursuant to this Section.
     In the event the Corporation prevails in any action or suit to enforce this
     Restated Key Employee Policy or arising from this Restated Key Employee
     Policy, it shall be entitled to such reasonable attorneys' fees as may be
     determined by the court.

(2)  Disclosure.

     All persons becoming key employees must accept their stock with knowledge
     of this Section and shall receive a copy of the Restated Bylaws of this
     Corporation together with this Restated Key Employee Policy. All persons
     becoming key employees are conclusively presumed to have full knowledge and
     understanding of this Restated Key Employee Policy and the Restated Bylaws
     and all duly adopted amendments thereto.

f. Redemption of Stock Pledged as Collateral.

(1)  Subject to the provisions of this Section, key employees may pledge part or
     all of their shares of stock in the Corporation as collateral for a loan or
     loans from a 

                                                                          PAGE 6
<PAGE>
 
     commercial bank, from the CH2M HILL Federal Credit Union, or any other
     financial institution approved by the Board of Directors.

(2)  In the event of a default by a key employee in repayment requirements of a
     loan secured by a pledge of said stock, and upon demand of the lender, the
     Corporation shall pay to the lender an amount equal to sixty (60) percent
     of the current market value (as defined in Section 3.c.(1) above) of the
     pledged stock, as adjusted for any stock splits, stock dividends and the
     like.

(3)  Upon payment by the Corporation to a lender as described in paragraph (2)
     above, the lender shall deliver the pledged stock together with an
     appropriate stock power endorsed in blank by the key employee to the
     Corporation. Thereafter, transfer of ownership of said stock free and clear
     of any interest of said key employee or said lending institution shall be
     made to the Corporation on the Corporation's books.


Section 4 - Retirement Policy.

a.   Normal/Mandatory Retirement.

     Key employees who are classified as employees in bona fide executive or
     high policy-making positions, as defined by applicable federal regulations,
     will have a mandatory retirement age of 65. Such key employees must retire
     as key employees and sell their shares of stock to the Corporation no later
     than January 1 of the year following their 65th birthday or at such later
     time that said classification is made, unless the Board of Directors
     affirmatively votes to continue such key employees beyond age 65.

b.   Voluntary Retirement.

     Key employees may retire as a key employee at any time following their 60th
     birthday. In order to retire, a key employee must terminate employment and
     sell all stock held to the Corporation.

c.   Employment After Retirement.

     Key employees, after retirement pursuant to Subsections a. and b. above,
     may be rehired as employees. Their compensation for such services shall be
     separate from any deferred compensation they may receive.


Section 5 - Incentive and Retirement Pay.

a.   Policy.

     The policy of the Corporation is that Key Employee Incentive Bonuses and
     Key Employee Bonuses After Retirement shall be payable at the discretion of
     the Board of 

                                                                          PAGE 7
<PAGE>
 
     Directors. Any such bonuses may be given additional or other names or
     acronyms as determined by the Board of Directors. In determining the amount
     of said bonuses the Board of Directors shall consider the general business
     condition of the firm, including such factors as performance,
     profitability, business projections, financial condition and capital
     requirements.

b.   Payment.

     Said incentive bonuses may be paid in cash, stock of this Corporation,
     other monetary instruments, or a combination , at the discretion of the
     Board of Directors.


Section 6 - Disability of Key Employee.

A permanently disabled key employee, either partially or fully, due to sickness
or accident, unless eligible for KEBAR as stipulated in Subsection 7. b. below,
shall receive a pro rata share of Key Employee Bonus for twelve (12) months
after first becoming disabled, and thereafter receive a portion of said bonus
which shall be determined on the basis of the key employee's continuing value to
the firm, as determined by a majority vote of the Board of Directors. The basis
for determining the degree of disability or whether the disability is temporary
or permanent shall be the same as that of the insurance company writing the
accident or sickness insurance which is making payments, or if it has no basis,
the standards of the Oregon State Industrial Accident Commission or its
successor agency shall apply.


Section 7 - Key Employee Bonus.

a.   Policy and Definition.

     Assuming the business conditions of the company permit, it is intended that
     the Directors declare an annual Key Employee Bonus. Said sum shall be
     available for Key Employee Bonuses (KEB) and Key Employee Bonuses After
     Retirement (KEBAR) to be allocated among the key employees at the
     discretion of the Board of Directors, based on the key employee's value to
     the firm and current performance.

b.   KEBAR.

(1)    Key Employees Selected after December 31, 1972  and Pension Offset.

       Because a Pension Plan for employees was established in 1973, key
       employees selected after December 31, 1972 shall not participate in
       KEBAR. The annual KEBAR payment to be paid to key employees selected
       prior to December 31, 1972 under the provisions of this Section 7. b. 
       (2) - (5), shall be reduced by the annual payment these employees could
       receive for the pensioner's life from the Pension Plan and other
       retirement programs during the period of KEBAR

                                                                          PAGE 8
<PAGE>
 
       payment if they were age 55 years at separation or at their actual age at
       separation, up to age 65, whichever is greater.

(2)    Declining Basis.

       A retired key employee, or one who withdraws not to compete shall
       participate on a declining basis in the Key Employee Bonus. Participation
       shall decline by ten (10) percent each year. In other words, for the
       first year of retirement or withdrawal, it shall be ninety (90) percent
       of what it would have been if the key employee had not retired or
       withdrawn, eighty (80) percent the second year, and so on. In the year
       following the ninth year of retirement or withdrawal, the participation
       of the retiring or withdrawing key employee shall be zero (0) percent.
       KEBAR payments made pursuant to a rating or evaluation system shall be
       based on the average rating over the last three (3) years of
       preretirement or prewithdrawal employment. Subject to other applicable
       limitations of the Key Employee Policy, permanently disabled, legally
       incapacitated key employees, or departing key employees over sixty (60)
       years of age shall participate in KEBAR the same as a retired employee.

(3)    20 Years Service for Full Amount.

       To receive full KEBAR pursuant to the above, an employee must be a key
       employee twenty (20) years prior to separation. Years of service as a
       partner in the predecessor partnership, Cornell, Howland, Hayes &
       Merryfield, through 31 December 1965, and any other longevity credit
       granted by the Board of Directors, will be considered key employee years,
       and will apply in computing eligibility for KEBAR. If a key employee
       completes fewer than twenty (20) years as a key employee before
       separation as provided in (2) above, the amount of KEBAR will be prorated
       in accordance with the number of years thus employed. Provided, however,
       this Section 7. b. (3) does not apply to persons who were key employees
       prior to 1 June 1968 who retire and do not compete.

(4)    Noncompetition.

       Persons shall not receive KEBAR as provided above if they compete with
       the Corporation or an affiliate after separation. In order to remain
       eligible for KEBAR, a separated key employee shall request in writing and
       receive approval of the Board of Directors of any employment after
       leaving the firm. The Board of Directors shall render a decision within
       30 days of receiving the written request or requests. The judgment of the
       Board of Directors as to what constitutes competition shall be
       conclusive.

(5)    Withdrawing Key Employee.

       A withdrawing key employee or a departing key employee less than sixty
       (60) years of age will receive KEBAR computed annually as if retired,
       except:

                                                                          PAGE 9
<PAGE>
 
               a)   The amount will be further adjusted in accordance with the
                    number of years the person has been a key employee to
                    provide for five (5) percent vesting for each year of being
                    a key employee. In other words, the key employee's right to
                    receive KEBAR will reach five (5) percent at the end of the
                    first year as a key employee and will increase five (5)
                    percent per year up to 100 percent at the end of the 20th
                    year as a key employee.

               b)   Payment for each annual KEBAR will be deferred for a period
                    of five years or payments will start at age 60, whichever
                    first occurs. For example, if a person age 53 who has been a
                    key employee four years withdraws as of December 31, 1970,
                    the key employee will accrue twenty (20) percent (four (4)
                    years times five (5) percent per year vesting when one
                    withdraws) of the amount they would have received if they
                    could have retired. (To retire one must be age sixty (60) or
                    above). In this case, the key employee will receive twenty
                    (20) percent of twenty (20) percent or four (4) percent of
                    full KEBAR as both the vesting and reduction for length of
                    service provisions apply in circumstances involving
                    withdrawal or termination by the Corporation or an affiliate
                    before age sixty (60) no matter what date key employee
                    status began. The first KEBAR payment would be computed as
                    of December 31, 1971 . The first payment will be made in
                    1977, providing the key employee does not compete in the
                    meantime. In the event of competition, the key employee
                    forfeits this and all subsequent KEBAR payments.

c. Method and Time of Payment After Separation.

   In the event a key employee who is entitled to a Key Employee Bonus is
   separated other than at the end of a year, Key Employee Bonus shall be paid
   on a prorated basis only for the part of the year prior to separation,
   except that a key employee who withdraws during the year to compete with
   the Corporation shall not be entitled to and shall not receive such
   prorated bonus. Payment for such bonuses will be made at the time KEB
   payments are made to key employees who worked for the entire year.

   If the person being separated is entitled to KEBAR, the first payment will
   be computed for the first full fiscal year after the year of separation
   from the firm and will be made, or accrue according to provisions of
   6.b.(5)(b) above, at the time normal KEB payment is made. If the person is
   separated other than at the end of a year, the first payment shall be on a
   prorated basis for the part of the year after separation. It is the intent
   that the key employee who is separated other than at the end of a year
   shall receive for that year a Key Employee Bonus on a prorated basis for
   the part of the year prior to separation, and the first payment for KEBAR
   on a prorated basis for the part of the year after separation, so that the
   total proration will cover all twelve (12) months of the year of
   separation. For example, if the key employee is separated on March 31 of a

                                                                         PAGE 10
<PAGE>
 
   year, they will receive 3/12 of the total Key Employee Bonus to which they
   would otherwise be entitled, and 9/12 of the payment for KEBAR. Each
   subsequent payment for KEBAR shall be on the basis of the remaining
   prorated amount to complete the annual payment for the prior year and the
   prorated amount for the current year. In the case of the example, the
   second payment for KEBAR would be 3/12 for the first year and 9/12 for the
   second year; the third payment 3/12 for the second year and 9/12 for the
   third year etc., until the 11th payment, which would be 3/12 for the tenth
   year.

d. Participation Terminates on Death.

   The right of a separated noncompeting key employee to participate in Key
   Employee Bonuses shall terminate on death and the share for the year of
   death shall be prorated. Payments which were deferred under (5)(b) above
   will be accrued and an interest-free promissory note for said amount
   payable to the estate in five (5) equal annual installments or sooner at
   the discretion of the Board of Directors, shall be delivered to the key
   employee's Executor or personal representative.
