                                    SUMMARY

          The following summary highlights selected information from this
prospectus and may not contain all of the information that is important to you.
This prospectus includes specific terms of the preferred stock, warrants,
underlying common stock and new notes, as well as information regarding our
business and detailed financial data. We encourage you to read this prospectus
in its entirety.

                              The Recapitalization

          Overview. The recapitalization will be completed in a series of
simultaneous transactions, each of which is dependent upon consummation of the
others. Assuming the conditions of the exchange offer are met:

          .    we will purchase up to $40 million principal amount of tendered
               old notes at par in an asset sale offer;

          .    for the remaining tendered old notes, we will exchange:

               .  preferred stock with a liquidation preference of $65 million
                  plus accrued interest on the old notes from July 1, 1999
                  through the date of the closing of the recapitalization,

               .  warrants to purchase approximately 15% of our common stock
                  on a fully diluted basis, and

               .  up to $25 million principal amount of new notes;

          .    holders of a majority of the outstanding old notes will consent
               to the amendment of the indenture governing the old notes; and

          .    we will enter into a new credit facility.

As a result of the recapitalization, holders of old notes will receive, for each
$1,000 of old notes tendered in the asset sale offer and the exchange offer,
$____ in cash, ____ shares of preferred stock, representing a liquidation
preference of $_____ plus a pro rata portion of the accrued interest on the old
notes from July 1, 1999 through the date of the closing of the recapitalization,
warrants to purchase ___% of our common stock on a fully diluted basis, and
$________ principal amount of new notes.

     The terms of the recapitalization are the product of negotiations with an
unofficial committee of holders of old notes owning in excess of 80% of the
aggregate principal amount of the old notes.

     Asset Sale Offer. In general terms, the indenture governing the old notes
requires us to use proceeds from asset sales to reduce senior indebtedness or
reinvest in our business or make an asset sale offer to purchase the old notes
at par, on a pro rata basis. As a result of the sale of our Consulting Group we
have approximately $40 million of available cash to fund an asset sale offer to
holders of our old notes.

     Exchange Offer. We are offering preferred stock, warrants and new notes
in exchange for all remaining tendered old notes not purchased in the asset
sale offer. Our acceptance of old notes tendered in the exchange offer is
conditioned on, among other things, holders of at least 95% of the principal
amount of old notes accepting the exchange offer and our obtaining a new credit
facility. In order to participate in the exchange offer, the holder of old notes
must tender all of the old notes beneficially owned by the holder.

     Consent Solicitation. Simultaneously with the exchange offer we are
seeking a consent from the holders of our old notes to remove substantially all
restrictive covenants and some defined events of default from the indenture
governing the old notes. In addition, we are requesting holders of the old notes
to deliver an instruction to the Trustee not to interfere with our
recapitalization. A holder of old notes does not need to consent to the proposed
amendments in order to tender its old notes in the exchange offer.

     New Credit Facility. We are in preliminary discussions with potential
lenders with respect to a new credit facility. The closing of any new credit
facility is conditioned on the successful completion of the recapitalization,
and obtaining a new credit facility is a condition of completing the exchange
offer. We anticipate that any new credit facility will provide for revolving
credit availability and the issuance of letters of credit. We expect the
availability of credit under the new credit facility will be a function of a
borrowing base determined with reference to eligible receivables. We further
anticipate that borrowings under the new credit facility will be secured by
substantially all of our assets.

                                       1
<PAGE>


     We do not expect to have available a new revolving credit facility until
the completion of the recapitalization. Until that time, we will cash
collateralize any letters of credit of the type often required to support
contract performance obligations and we will utilize other available cash for
working capital purposes.


                      Rationale for the Recapitalization

     The amount of cash flow currently available from our remaining operations
is insufficient to service the interest expense associated with our existing
debt obligations. We are also significantly more leveraged than our competitors.
Especially in the recent past, this has sometimes impaired our ability to win
new business. Additionally, our current financial position has impaired and
could in the future impair our ability to retain key personnel. A realignment of
our capital structure through the recapitalization will substantially reduce our
level of debt and associated interest expense, and we believe we will be better
able to service remaining obligations after the recapitalization. We also
believe the recapitalization will enhance our ability to win new business and
retain and attract key employees. The completion of the recapitalization is a
condition to our securing a new credit facility, which is necessary to support
short-term liquidity needs and letters of credit.

     If the recapitalization is not consummated, we may continue to negotiate
with the holders of the old notes and senior notes for a recapitalization, we
may invest the proceeds from the sale of our Consulting Group in a related
business investment or we may seek implementation of the recapitalization
through a so-called "prepackaged" plan of reorganization. See "Possible
Prepackaged Plan of Reorganization." If we were to seek implementation of a
recapitalization through confirmation in a bankruptcy proceeding, no assurance
can be given that the recapitalization would meet the requirements for
confirmation under the U.S. Bankruptcy Code even if the requisite consents are
received and the old notes subject to the consents are voted to accept the
recapitalization.

             Cautionary Note Regarding Forward-Looking Statements

     This prospectus contains what we believe are forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995. They
are statements about future performance or results such as statements including
the words, "believe," "expect" and "anticipate" when Kaiser discusses its
financial condition, results of operations and business. Forward-looking
statements involve risks, assumptions and uncertainties. They are not guarantees
of future performance. Factors may cause actual results to differ materially
from those expressed in these forward-looking statements. These factors include
those identified under the caption "Risk Factors" in this prospectus, as well as
the factors identified under the caption "Management's Discussion and Analysis
of Financial Condition and Results of Operations" contained in Kaiser's
Quarterly Report on Form 10-Q for the quarterly period ended June 30, 1999 that
is incorporated by reference into and delivered with this prospectus.

     We believe that the expectations reflected in our forward-looking
statements are reasonable. However, we cannot assure you that these expectations
will prove to be correct. You should consider the factors we have noted under
the captions stated above as you read this prospectus.

                                            to the old notes tendered pursuant
                                            to the exchange offer.

Tax Consequences of the Exchange..........  The exchange, taken together with
                                            the cash purchase of old notes
                                            pursuant to the asset sale offer,
                                            should qualify as a recapitalization
                                            under the Internal Revenue Code. If
                                            that is the case, a holder of old
                                            notes who participates in both the
                                            exchange and the asset sale offer
                                            will recognize taxable gain, but not
                                            loss, equal to the lesser of the
                                            cash plus the fair market value of
                                            the new notes received or the
                                            aggregate amount of gain realized on
                                            the exchange and cash purchase of
                                            old notes. However, if the Internal
                                            Revenue Service were to successfully
                                            claim that the exchange of old notes
                                            and the cash purchase of old notes
                                            pursuant to the asset sale offer
                                            should be treated independently of
                                            each other for federal income tax
                                            purposes, a holder of the old notes
                                            who participates in both the
                                            exchange and the asset sale offer
                                            would recognize taxable gain, but
                                            not loss, on the exchange equal to
                                            the lesser of the fair market value
                                            of the new notes received or the
                                            amount of gain realized on the
                                            exchange and would recognize taxable
                                            gain or loss on the purchase of the
                                            old notes pursuant to the asset sale
                                            offer. Further, if the Internal
                                            Revenue Service were to successfully
                                            claim that the exchange does not
                                            qualify as a recapitalization, the
                                            holders of old notes who participate
                                            in the exchange offer and/or the
                                            asset sale offer would be required
                                            to recognize taxable gain or loss on
                                            both the exchange and the cash
                                            purchase. See "United States Federal
                                            Income Tax Considerations."

                                                become effective, they will
                                                apply to all old notes issued
                                                under the old notes indenture,
                                                and each holder of old notes not
                                                tendered or accepted for
                                                exchange pursuant to the
                                                exchange offer will be bound by
                                                the proposed amendments
                                                regardless of whether the holder
                                                consented to the proposed
                                                amendments.

                Possible Prepackaged Plan of Reorganization

Alternative Implementation of
  Recapitalization..........................    If holders of 95% of the
                                                outstanding old notes do not
                                                tender their old notes in the
                                                exchange offer but we obtain a
                                                substantial level of support for
                                                the recapitalization, we may
                                                elect to implement that
                                                recapitalization through a
                                                "prepackaged" plan of
                                                reorganization under Chapter 11
                                                of the Bankruptcy Code having
                                                the same terms and conditions as
                                                regards the holders of old notes
                                                as contemplated by the
                                                recapitalization. Such a plan of
                                                reorganization would not affect
                                                Kaiser's operations, vendors or
                                                employees.

Binding Effect of Plan......................    If confirmed by the Bankruptcy
                                                Court, a prepackaged plan of
                                                reorganization would bind all
                                                holders of old notes, without
                                                regard to whether they tendered
                                                their old notes in the exchange
                                                offer or the asset sale
                                                offer.

Effectiveness of Tenders of
  Old Notes.................................    Tenders of old notes and related
                                                documentation may not be
                                                withdrawn after delivery and may
                                                be counted as ballots in favor
                                                of a plan of reorganization in a
                                                Chapter 11 case.


                                  The Company

     We are a global provider of engineering, construction management, and
project and program management services.  We also own a 50% interest in Kaiser-
Hill Company, LLC, which serves as the integrated management contractor at the
U.S. Department of Energy's Rocky Flats Environmental Technology Site.

     We completed the sale of our Environment and Facilities Management Group on
April 9, 1999 for net cash proceeds, after a working capital adjustment, of $74
million and on June 30, 1999 we sold 90% of our Consulting Group for $64 million
in cash, plus $6.6 million of interest bearing notes.  These actions were taken
in response to substantial losses incurred primarily in 1998 in connection with
fixed price contracts to construct four nitric acid plants.

     We are now focused on serving clients in five major lines of business:

     .  Transit and Transportation - Our transit and transportation services
        support the planning, design, engineering, and construction of heavy-
        and light-rail transit systems, high-speed rail, peoplemovers, bus
        systems, highways and bridges, and airport improvements.

     .  Alumina/Aluminum - We provide design and construction services for
        expansion and modernization of some of the world's largest alumina and
        aluminum facilities in locations from Kentucky to the Middle East and
        Australia.

                                       7
<PAGE>


     . Facilities and Water/Wastewater - We provide engineering services to
       public-and private-sector clients who need to modernize or maintain
       facilities, to design and build new capacity for the future, or to
       improve existing operations and environmental conditions. Such facilities
       include, but are not limited to, water supply and wastewater treatment
       facilities.

     . Iron and Steel - We support the iron and steel industry by providing
       traditional services such as engineering, design, and project and
       construction management for plant expansions, modernizations, and
       greenfield development.

     . Microelectronics and Clean Technology - We also provide design/build
       services for the microelectronics, semiconductor, biotechnology, and
       telecommunication industries.

Our business is global in nature with more than 30 offices worldwide.

     We own Kaiser-Hill Company, LLC equally with CH2M Hill Companies Ltd. We
designate a majority of the members of Kaiser-Hill's Board of Managers. Kaiser-
Hill currently serves as the integrated management contractor at the U.S.
Department of Energy's Rocky Flats Environmental Technology Site near Denver,
Colorado. The scope of Kaiser-Hill's contract with the DOE includes all elements
of daily and long-term operation of the site, including stabilizing and safely
storing more than 14 tons of plutonium, cleaning up areas contaminated with
hazardous and radioactive waste, and restoring much of the 6,000-acre site for
future use by the public. Kaiser-Hill's contract with the DOE currently expires
in September 2000. On July 30, 1999, the DOE announced that it intends to
negotiate with Kaiser-Hill for a new contract for services through the closure
of the Rocky Flats site in 2006. Such negotiations are expected to begin in
early October. The DOE has stated that if a new contract has not been entered
into by November 30, 1999, it intends to conduct a competition for the new
contract. We can provide no assurance as to Kaiser-Hill's ability to compete for
or win a new contract if Kaiser-Hill is unable to enter into a new contract
through negotiations.

                                   Strategy

     Our strategy is to grow the revenue base of our remaining operations and
improve profitability.  We will focus on new business development, cost
reductions and stringent project and operating controls to achieve this goal.

     New Business Development.  With the nitric acid projects behind us, the
realignment of our capital structure will enable us to focus on expanding our
revenue base.  We believe our expertise in our core lines of business and
worldwide presence and recognition for quality service delivery can be leveraged
into significant opportunities in the future.  We will seek additional contracts
with our existing customers and utilize our expertise from our current projects
to win business from new clients.

     Cost Reductions.  Concurrently with the planning for the sales of the EFM
and Consulting Groups, we identified approximately $20 million of cost reduction
opportunities in our remaining operations.  Upon elimination of these costs, we
will have aligned our cost structure with our remaining revenue base.  By
changing the way we manage our business to a line of business focus with only
two regions - North America and International - we will be able to eliminate a
layer of overhead including personnel and facilities costs.  In addition to
reductions in overhead, reductions in technical personnel resulting in higher
revenue per employee will improve profitability.  As of July 31, 1999, we have
effected approximately 80% of these cost reductions.

     Stringent Controls.  Following the identification of our nitric acid plant
related problems we, along with several outside consultants, thoroughly reviewed
our policies and procedures in all phases of a contract lifecycle.  As a result,
we have implemented:

     .  stronger financial and operating controls and project evaluation
        processes;

     .  frequent senior management reviews of progress and profitability of each
        contract; and

     .  a new project management reporting system that will allow us to more
        proactively manage profitable project execution.

                            Summary Financial Data

     The following statement of operations, basic and diluted (loss) per share
data, and balance sheet data, excluding the data for the six months ended and as
of June 30, 1999, has been derived from Kaiser's audited financial statements.
The information should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and with our
consolidated financial statements and related notes, incorporated by reference
in this prospectus.

     Effective January 1, 1999, the results of operations from the EFM and
Consulting Groups were treated as discontinued operations and were excluded from
the statement of operations data.  Accordingly, the statement of operations data
for the six months ended June 30, 1999 is not comparable to the data for the
prior periods presented.

(a)  Service revenue is calculated by deducting the costs of subcontracted
     services and other direct costs from the gross revenue and adding our share
     of the income or loss of joint ventures and affiliated companies.
(b)  Includes direct labor and fringe benefits, group overhead and corporate
     general and administrative expense.
(c)  Minority interest represents CH2M Hill's fifty-percent ownership of Kaiser-
     Hill.
(d)  EBITDA, as presented, includes operating income (loss) plus depreciation
     and amortization, severance and restructuring charges, and unusual charges
     and minus minority interest.  We believe that EBITDA provides useful
     information regarding our ability to service our indebtedness, but should
     not be considered in isolation or as a substitute for operating income or
     cash flow from operations, in each case as determined in accordance with
     generally accepted accounting principles, as an indicator of our operating
     performance or as a measure of our liquidity.
(e)  Earnings for these periods are inadequate to cover fixed charges.  The
     deficiency, calculated as the dollar amount of earnings required to attain
     a ratio of one-to-one, for the year ended February 28, 1995, December 31,
     1998 and the six months ended June 30, 1999 was $2,848, $103,146 and
     $26,495, respectively.
(f)  Includes unamortized discounts.

          The following financial information represents the results from
continuing operations for the three months ended June 30, 1999, as annualized
and adjusted for the effects of the following:

          .  the anticipated increase in our service revenue based upon internal
             management projections, as compared to the annualization of the
             results from continuing operations during the second three months
             of 1999; and

          .  the full-year effect of our cost reduction plan as a result of the
             scheduled separation of approximately 200 employees.

          The results from continuing operations presented in the table exclude
the operating results of our EFM and Consulting Groups, which were sold during
the second quarter of 1999 and whose results were otherwise included in Kaiser's
results from discontinued operations not presented in the table.

          We believe that the annualization of the continuing operating results
for the three months ended June 30, 1999 is a reasonable basis upon which to
present the effects of the adjustments noted above:

          .  since that quarter's results, excluding nonrecurring charges,
             reflect the most recent actual results and may represent the near-
             term future recurring operating trends; and

          .  since the cost reduction plan was largely designed, planned and
             executed based on the cost trends and operating results, excluding
             nonrecurring charges, experienced during that quarter.

          This financial data is provided for information purposes only and is
not intended to project our results of operations or financial position for any
future period or as of any future date. The information is based on our
unaudited historical financial information for the three months ended June 30,
1999 and should be read in conjunction with the related notes and "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
included in our quarterly report on Form 10-Q for the period ended June 30,
1999, that is incorporated by reference into this prospectus.

(a)  Service revenue is calculated by deducting the costs of subcontracted
     services and other direct costs from the gross revenue and adding our share
     of the income or loss of joint ventures and affiliated companies.
(b)  Severance and restructuring charges and other unusual charges incurred
     during the three months ended June 30, 1999 have not been included in the
     annualized run rate column as operating costs.
(c)  Minority interest represents CH2M Hill's fifty-percent ownership of Kaiser-
     Hill.
(d)  EBITDA, as presented above, includes operating income (loss), plus
     depreciation and amortization, severance and restructuring charges, and
     unusual charges and minus minority interest.  Other unusual charges
     incurred during the three months ended June 30, 1999 have not been included
     in the annualized run rate column and have accordingly been excluded from
     this definition of EBITDA.  We believe that EBITDA as presented here
     provides useful information regarding our ability to service our
     indebtedness, but should not be considered in isolation or as a substitute
     for operating income or cash flow from operations, in each case as
     determined in accordance with generally accepted accounting principles, as
     an indicator of our operating performance or as a measure of our liquidity.

     The assumed increase in service revenue and the assumed decrease in costs
from the cost reduction plan are not predictions of actual future results. You
should not assume that the increase in service revenue and the decrease in costs
necessarily will occur. Accordingly, you should not use or rely on this
information as an indication of actual future results. The foregoing projections
constitute what we believe are forwarding-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. Forward-looking
statements involve risks, assumptions and uncertainties. There can be no
assurance that future developments will be in accordance with Kaiser's
expectations. See "Cautionary Note Regarding Forward-Looking Statements."

                                 RISK FACTORS

     An investment in the securities described in this prospectus involves a
high degree of risk.  You should consider carefully the following factors, in
addition to the other information contained in this prospectus, before
participating in the exchange offer.

Specific factors related to our financial performance may adversely affect our
ability to pay interest and principal on our debt.

     Sale of operating groups will reduce cash flow.  During the first half of
1999, we sold our EFM and Consulting Groups.  Prior to their sale, these groups
had generated cash that was used to support Kaiser's operations and debt
service.  In the recent past, apart from Kaiser's interest in Kaiser-Hill
Company, LLC, Kaiser's other operating units have not generated positive cash
flow.

     We rely heavily on a plan to reduce expenses and increase cash flow, which
may not be successful.  Our success will be dependent, to a large extent, on our
ability to execute promptly and effectively our plan to reduce operating
expenses, increase margins and enhance cash flow from remaining operations.

     We are dependent on key customers, and the loss of any of them could
materially affect us.  Our future profitability is dependent, to a significant
extent, on Kaiser-Hill's entering into a new contract with DOE.  We have several
other key clients, the loss of any of which would have a significant material
adverse effect on our ability to return to profitability.  The loss of a
significant client could impair our ability to compete for new clients and have
a significant negative impact on Kaiser's future growth.

     We intend to continue bidding and entering into fixed price contracts,
which may not be completed profitably.  Our recent history of financial losses
is partially attributable to our failure to accurately bid on, and our inability
to perform, fixed price contracts, specifically with respect to the nitric acid
plants.  Despite this performance history, the nature of our business is such
that we believe it is necessary for us to continue to enter into fixed price
contracts.  Although we believe we have put appropriate controls in place such
that we can successfully bid and perform fixed price contracts, we give no
assurances that all future fixed price contracts will be completed profitably.

     The remaining operations may not be able to retain or attract the personnel
needed for growth and profitability.  Our future performance will depend to a
significant extent upon the efforts and abilities of senior executives, line of
business managers and other key employees.  Our current financial circumstances
make it more difficult to retain key managers, and the loss of the services of
these managers could have a material adverse effect on us.  In addition, because
our remaining operations are service-oriented in nature, our ability to deliver
these services in a cost-effective and high quality manner depends upon our
ability to attract, retain, and properly manage a staff of qualified
professionals with the necessary skills.  The market for these professionals is
quite competitive and our current financial circumstances make it more difficult
to attract these professionals.

     The remaining operations may not grow and become profitable in their highly
competitive markets.  We compete with many other firms ranging from small firms
to large multinational firms having substantially greater financial, management
and marketing resources.  Other competitive factors include quality of services,
technical qualifications, reputation, geographic presence, price, and the
availability of key professional personnel.  In order for us to become
profitable, we will have to successfully compete against these firms in order to
generate additional backlog of service contracts, including an extension of the
current contract or award of a new contract for Kaiser-Hill.

     Holders of old notes may have to surrender any payments received from
Kaiser pursuant to the asset sale offer if the payments are found to be
avoidable preferences under the U.S. Bankruptcy Code.  In the event we were to
file for relief under Chapter 11 of the U.S. Bankruptcy Code within 90 days or
possibly one year of the payment date, the payments may be avoidable as a
preference and could be subject to recovery by a trustee in bankruptcy, an

                                       13
<PAGE>


official creditors' committee, or other representatives of creditors of Kaiser
as a debtor in possession.  If the payments were successfully challenged as a
preference, holders either would be required to return the funds received,
together with interest in a rate determined by the court, or would be precluded
from receiving any distribution on account of the holders' old notes.

Our financial performance is significantly tied to Kaiser-Hill, which is subject
to uncertainties that may adversely affect its and our operating results.

     If Kaiser-Hill does not successfully negotiate a new DOE contract, we will
lose a significant portion of our cash flow and value.  The contract with DOE
under which Kaiser-Hill operates expires in September 2000.  Although we believe
DOE will enter into a new contract with Kaiser-Hill, it is possible that after
negotiating with Kaiser-Hill, DOE will conduct a competition for a new contract.
Kaiser-Hill may not be able to compete for or win a new contract if a
competition is conducted by DOE.  If Kaiser-Hill does not successfully negotiate
or win a new contract in any competition that is held, we will lose a
significant portion of our cash flow and value.

     There are special Federal regulations that could adversely affect Kaiser-
Hill's DOE contract.  Because Kaiser-Hill provides the Federal government with
nuclear energy and defense- related services, it and a number of its employees
are required to have and maintain security clearances from the Federal
government.  There can be no assurance that the required security clearances
will be obtained and maintained in the future.  In addition, Kaiser-Hill is
subject to foreign ownership, control and influence regulations imposed by the
Federal government and designed to prevent the release of classified information
to contractors subject to foreign ownership, influence and control.  There can
be no assurance that foreign ownership, influence and control concerns will not
affect the ability of Kaiser-Hill to secure and maintain its DOE contract.

     There are potential substantial liabilities and costs associated with
Kaiser-Hill's DOE contract.  Kaiser-Hill performs DOE's Performance Based
Integrating Management Contract at DOE's Rocky Flats Environmental Technology
Site near Denver, Colorado.  Rocky Flats is a former DOE nuclear weapons
production facility.  Under the DOE contract, Kaiser-Hill is responsible for,
and DOE will not pay for costs associated with, liabilities caused by the
willful misconduct or lack of good faith of Kaiser-Hill's managerial personnel
or the failure to exercise prudent business judgment by Kaiser-Hill's managerial
personnel.  If Kaiser-Hill were found liable for any of these reasons, the
associated costs could be substantial.

We face significant contingencies, which may adversely impact our ability to
meet our obligations on our debt and preferred stock and our ability to fund
continuing operations.

     We have retained obligations relating to the operating groups that were
sold.  We have indemnified the purchasers of the EFM and Consulting Groups we
sold against breaches of representations and warranties and covenants included
in the sale agreements.  We also have retained some potential liabilities
arising from the pre-closing operations of these operating groups.  These
retained liabilities relate primarily to potential liabilities arising out of
ongoing federal government audits of certain activities of the operating groups
prior to their sale.

     We have a potential liability from a contract with Bath Iron Works as to
which we currently cannot estimate the outcome.  In March 1998, we entered into
a $197 million maximum price contract to construct a ship building facility for
Bath Iron Works.  In May 1998, we learned that estimated costs to perform the
contract as reflected in actual proposed subcontracts were approximately $30
million higher than the cost estimates originally used as the basis for contract
negotiation between us and our customer.  After learning this, we advised the
customer that we were not required to perform the contract in accordance with
its terms as a result of a mutual mistake between us in negotiating that
contract.  In October 1998, our customer presented an initial draft of a claim
against us requesting payment for estimated damages and entitlements pursuant to
the terminated contract.  No provision for loss from this matter has been
included in our financial results to date as management does not believe that it
has sufficient information to reasonably estimate the outcome as negotiation
activity has not been significant to date.

     We have contingencies from a recent acquisition that could require us to
use cash that might otherwise be available for debt service or operations.  In
March 1998, we acquired ICT Spectrum Constructors, Inc. by issuing common stock
in exchange for the stock of ICT Spectrum.  We guaranteed that the market value
of each of the 1.5

                                       14
<PAGE>


million shares of common stock issued in the acquisition will reach $5.36 by
March 1, 2001. In the event that the market value does not attain the guaranteed
level, we are obligated to make up the shortfall either through the payment of
cash or by issuing additional shares of common stock with a total value equal to
the shortfall, depending upon our preference. Under the terms of the agreement,
however, the total number of contingently issuable shares of common stock cannot
exceed an additional 1.5 million. Given recently quoted prices of our stock, the
assumed issuance of an additional 1.5 million shares would not completely
extinguish the purchase price contingency and we would be required to pay a cash
fill-up to satisfy the contingency. Any future distribution of cash or common
stock would be recorded as a charge to our paid-in-capital. Until the earlier of
the resolution of the contingent purchase price or March 1, 2001, any additional
shares assumed to be issued because of shortfalls in market value will be
included in our diluted earnings per share calculations, unless they are
antidilutive. The exchanged shares also contain restrictions preventing their
sale prior to March 1, 2001.

     On March 29, 1999, one ex-ICT Spectrum shareholder, individually and on
behalf of all others similarly situated, filed a class action lawsuit alleging
false and misleading statements made in a private disclosure document, and
asserting other claims, in connection with our acquisition of ICT Spectrum.  We
have filed a motion to dismiss the plaintiffs' amended complaint.

     There may be Y2K compliance issues associated with the remaining
operations.  During recent years, there has been significant global awareness
raised regarding the potential disruption to business operations worldwide
resulting from the inability of current computer software to process properly
the change from the year 1999 to 2000.  We have reviewed our data processing,
operating and other computer-based systems, and we do not currently anticipate
any material disruption in our operations as a result of any failure by us to
achieve year 2000 compliance, but we cannot give any assurance to that effect.
Even if our computer operations are unaffected by the year 2000, our business
operations may be interrupted or adversely affected as a result of year 2000
complications experienced by our subcontractors, clients, vendors, or general
business interruptions experienced domestically or internationally.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Other Matters - Year 2000 Readiness" in the Annual Report  on Form
10-K enclosed with this prospectus.

There are significant financial risks associated with the preferred stock,
warrants, underlying common stock and new notes, which could adversely affect
the value of the preferred stock, warrants, underlying common stock and new
notes.

     There may not be a trading market for the preferred stock, warrants and new
notes. The preferred stock, warrants and new notes are new issues of securities
for which there are currently no established trading markets.

     We cannot assure you that a trading market for the preferred stock,
warrants or new notes will develop.  The absence of a trading market adversely
affects the liquidity of your shares of preferred stock, warrants and new notes
and it may be difficult for you to sell these securities.  We do not intend to
apply for listing of the warrants or the new notes on any national securities
exchange or for quotation through any over-the-counter market and there is no
assurance that we will be able to obtain listing or quotation of the preferred
stock.  If your shares of preferred stock, warrants or new notes are traded,
they may trade at a substantial discount from their face or liquidation value or
at a substantial discount to the implied value of the warrants taking into
account their exercise price, as the case may be.  Any discount could depend
upon a number of factors, including:

     .  the market demand for the preferred stock, warrants or new notes, as the
        case may be;

     .  the market for similar securities;

     .  the financial condition and performance of Kaiser;

     .  prevailing dividend and interest rates generally in the financial
        markets; and

     .  general economic conditions.

                                       15
<PAGE>


     Our ability to pay the liquidation preference and dividends on the
preferred stock depends on our financial condition at that time.  Our
obligations to the holders of our debt and other creditors take priority over
our obligations to the holders of the preferred stock.  Under Delaware law, we
may not redeem the preferred stock for its stated liquidation preference if at
that time our remaining assets are not sufficient to pay our outstanding
obligations or if that redemption would impair our capital.  See "Description of
Convertible Preferred Stock" on page 48 of this prospectus.

     Preferred stock and warrants could result in potential dilution and impair
market price.  To the extent that the preferred stock and warrants are converted
or exercised into our common stock, our existing shareholders will experience
dilution in their percentage ownership of Kaiser.  So long as the preferred
stock and warrants are exercisable, the holders of these securities will have
the opportunity to profit from a rise in the price of our common stock.  The
additional shares of common stock available for sale in the market may have a
negative impact on the price and liquidity of the common stock that is currently
outstanding.

     Preferred stock, warrants and new notes may have an adverse impact on
additional financing.  The holders of the preferred stock and warrants are more
likely to convert or exercise them at a time when we may be able to obtain
additional capital by an offering of our stock at a price higher than the
conversion or exercise price of the preferred stock and warrants.  This may make
it more difficult to obtain additional financing at a time when additional
financing may be necessary or desirable to sustain current or increased levels
of operations.  In addition, the new notes will represent new outstanding debt
for Kaiser.  Potential lenders may look unfavorably at our total debt level with
this additional debt, making it more difficult for us to obtain additional
financing.

     The repayment of new notes is not secured by our assets.  Our obligation to
make payments of principal and interest on the new notes is unsecured.  As a
result, holders of the new notes will not have any ability to use our assets as
collateral for the repayment of these obligations.  In addition, if we become
subject to a bankruptcy or liquidation proceeding, the right of holders of the
new notes to be repaid will be limited to the assets available after all of our
secured creditors have been satisfied.  These remaining assets will then be
distributed among the remaining unsecured creditors, including trade creditors,
as well as holders of the new notes.  As a result, holders of the new notes may
not recover their investment in these new notes. We are currently pursuing
alternatives for a new secured credit facility. On a pro forma basis, assuming
we are successful in obtaining that secured credit facility, the new notes
would be effectively subordinated to approximately [$30 million] of secured
indebtedness.

     The new notes will be subordinated to liabilities of some of our
subsidiaries. Substantially all of our operations are conducted, and
substantially all of our assets are owned, by our subsidiaries. The new notes
will effectively be subordinated to all existing and future liabilities of those
of our subsidiaries that have not guaranteed the new notes. Any right we may
have to participate in any distribution of the assets of any of our subsidiaries
upon the subsidiary's liquidation, reorganization or insolvency, and any right
the holders of the new notes may consequently have to participate in the
distribution of those assets, will be subject to the claims of the creditors,
including trade creditors, of the subsidiary. In addition, in the event we
have valid claims as a creditor of a subsidiary that are recognized, these
claims would be subordinated to any security interest in the assets of the
subsidiary and any indebtedness of the subsidiary senior to that held by us. As
of June 30, 1999, on a pro forma basis after giving effect to the
recapitalization, the aggregate principal amount of indebtedness of our
subsidiaries which would have effectively ranked senior to the new notes would
have been approximately [$____ million].

     Our common stock could be delisted from the New York Stock Exchange, which
may adversely affect holders of our common stock.  Our common stock is listed on
the New York Stock Exchange.  In order to continue to be listed on the NYSE, we
must meet specific quantitative standards.  On August 5, 1999, the NYSE notified
us that we were "below criteria" regarding newly effective continued listing
standards.  This means we are subject to the NYSE's procedures under which the
NYSE evaluates whether a listed company has a plan to bring it into conformity
with the applicable continued listing criteria or whether a company should be
delisted from the NYSE.  We do not know whether our proposed recapitalization
and other ongoing programs will be sufficient to bring us into conformity with
the applicable continued listing criteria.  Although we would have an
opportunity to appeal any decision by the NYSE to delist its common stock, there
can be no assurance that this appeal would be successful.  If our common stock
were delisted from the NYSE, we would seek to have the common stock listed on
another exchange, such as AMEX or one of the regional exchanges, or quoted in
the Nasdaq National or SmallCap markets.  However, many of these exchanges and
markets also have minimum quantitative standards that we may be unable to meet.
If our common stock is delisted from the NYSE and we are unable to have our
shares included on another exchange or in the over-the-counter market,
shareholders may find it more difficult to dispose of the shares or to

                                       16
<PAGE>


obtain accurate quotations of the market value of the shares. In addition, the
market price of the shares could decline, news coverage about us could decline,
and we could find it more difficult to obtain financing in the future.

     Kaiser does not anticipate that it will pay any dividends on its common
stock in the foreseeable future, which adversely affects the value of our common
stock.  We have never paid dividends on our common stock and anticipate
retaining all earnings for use in our business rather than paying cash dividends
in the foreseeable future.  Our ability to pay cash dividends on our common
stock has been substantially restricted under the indentures governing our
outstanding debt.  The new credit facility also will likely contain provisions
prohibiting us from paying dividends without the consent of the lender.  These
contractual restrictions will limit our ability to pay dividends in the future.

     Issuance of shares to former holders of ICT Spectrum stock could cause
significant dilution.  As noted above, if we are required to issue shares to
extinguish the ICT Spectrum purchase price contingency, there will be
significant dilution to shareholders.

If the recapitalization is completed, holders of old notes not tendered in the
exchange offer or in the asset sale offer will have reduced rights under the
governing indenture and may find it difficult to sell their old notes.

     The amendments to the indenture governing the old notes will have the
effect of reducing the rights of the holders of old notes not tendered in the
exchange offer or in the asset sale offer.  Concurrent with the exchange offer,
we propose to amend the indenture that governs the old notes by eliminating
substantially all of the covenants that restrict our activities and those of our
subsidiaries.  Under the indenture governing the old notes, holders of the old
notes currently have the right to enforce these covenants upon us.

     The market price of the old notes may decline.  If the exchange offer is
successful, the amount of old notes outstanding will be substantially reduced.
As a result, it may become much more difficult for holders to sell their old
notes.  In addition, the reduced liquidity of old notes outstanding after the
recapitalization could have the effect of reducing the market price at which the
old notes may be sold.

                                CAPITALIZATION

  The following table sets forth our capitalization as of June 30, 1999, pro
forma to give effect to the settlement of the senior notes and certain other
transactions subsequent to June 30, 1999 and adjusted to give effect to the
consummation of the recapitalization as if it had occurred on June 30, 1999.
The information set forth below should be read in conjunction with our audited
financial statements and unaudited pro forma financial statements, together with
the related notes, included and incorporated by reference in this prospectus.

                      RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our ratio of earnings to fixed charges for
the five years ended December 31, 1998 and the six months ended June 30, 1999.
The ratio of earnings to fixed charges has been calculated by dividing fixed
charges into the sum of fixed charges and income from continuing operations
before income tax expense and before equity in earnings or losses of less than
fifty-percent owned companies.  Fixed charges consist solely of interest costs.

                   UNAUDITED PRO FORMA FINANCIAL STATEMENTS

     The following unaudited pro forma financial statements are derived from our
historical financial statements incorporated by reference into this prospectus.

     .    The unaudited pro forma statement of operations for the year ended
          December 31, 1998 reflects the sale of our EFM and Consulting Groups
          and the completion of the recapitalization described in this
          prospectus, as if these transactions had occurred on January 1, 1998.

     .    The unaudited pro forma balance sheet at June 30, 1999 reflects the
          completion of the recapitalization described in this prospectus, as
          well as several other transactions, as described in the notes to the
          pro forma financial statements, as if they had occurred at June 30,
          1999.

     .    The unaudited pro forma statement of operations for the six months
          ended June 30, 1999 reflects the operating results of the EFM and
          Consulting Groups as discontinued operations. As a result, they have
          been excluded from gross revenue, service revenue, operating income
          (loss), other income (expense) and all information concerning
          continuing operations for that period.

The unaudited pro forma financial statements should be read in conjunction with
the related notes, with the "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and with our historical financial
statements, including the related notes, incorporated by reference into this
prospectus.

     The pro forma adjustments to give effect to the various events described
above are based upon currently available information and upon assumptions that
management believes are reasonable.  The pro forma financial statements are
provided for information purposes only and should not be construed to be
indicative of our results of operations or financial position had the
transactions described above been consummated on or as of the dates assumed, and
are not intended to project our results of operations or financial position for
any future period or as of any future date.

      extinguish an equivalent amount of the old notes.  A total of 2,600,000
      shares with a par value of $.01/share.

  12. To write-off the remaining $2.1 million of unamortized carrying value of
      the costs incurred by Kaiser to issue the old notes.

  13. To record the $2.0 million estimate of the costs, including professional
      fees, to be incurred for debt modification as part of this exchange offer.

  14. To record the $0.5 million estimate of costs, including professional fees,
      to be incurred to issue the new preferred stock as a charge to paid-in
      capital.

Quasi-Reorganization

      of the accumulated deficit after the completion of the exchange offer
      transactions assuming shareholder approval.

                OVERVIEW AND BACKGROUND OF THE RECAPITALIZATION

     Kaiser incurred losses during 1997, 1998 and the first six months of 1999
of an aggregate of approximately $129 million, largely as a result of
significant cost overruns on fixed price contracts to construct four nitric acid
plants.  During the second half of 1998, Kaiser's Board of Directors formed a
special committee of members of the Board to consider strategic alternatives for
Kaiser.  The special committee engaged a financial advisor and, with its
assistance, evaluated various opportunities available to Kaiser, including the
sale of one or more of Kaiser's operating groups.  As a result of that process,
Kaiser sold its EFM and Consulting Groups during 1999.

     Because of the cash drain and continuing obligations associated with
Kaiser's nitric acid plants and other losses, the sales of the EFM and
Consulting Groups were not enough to restore Kaiser's financial condition.
Kaiser has lost the earning power associated with the sold operating groups and
continues to have significant outstanding debt, principally $125 million of the
old notes.

     The Board of Directors considered several alternative means of stabilizing
Kaiser's financial condition.  Among the alternatives considered was the use of
the proceeds from the Consulting Group sale in an acquisition of a related
business or simply reinvesting the proceeds from the Consulting Group sale into
Kaiser's existing business activities.  In considering these alternatives, the
Board of Directors met several times, reviewed the recommendations of its
financial, legal and other professional advisors, as well as the information
provided by management, and closely analyzed the information available to it.
The Board of Directors ultimately determined that the recapitalization described
in this prospectus represents the most advisable approach to significantly
improving Kaiser's financial position and future business prospects.  As a
result of the process of negotiating the terms of the recapitalization, Kaiser
purchased all of its outstanding 12% Senior Notes due 2003 on September 30,
1999.

     As described in more detail below, the Board of Directors has approved a
recapitalization that consists of an exchange offer, an asset sale offer and
amendments to the indenture governing the old notes.  If this recapitalization
is not consummated, Kaiser may continue to negotiate with the holders of the old
notes for a recapitalization, Kaiser may invest the proceeds in a related
business investment or Kaiser may seek implementation of the recapitalization
through a so-called "prepackaged" plan of reorganization.  See "Possible
Prepackaged Plan of Reorganization."  If Kaiser were to seek confirmation of the
recapitalization in a bankruptcy proceeding, no assurance can be given that the
recapitalization would meet the requirements for confirmation under the U.S.
Bankruptcy Code even if the requisite consents are received and the old notes
subject to the consents are voted to accept the recapitalization.


                               THE EXCHANGE OFFER

Terms of the Exchange Offer

     Kaiser is offering to exchange preferred stock with a liquidation
preference of $65 million plus accrued interest on the old notes from July 1,
1999 through the date of the closing of the recapitalization, warrants to
purchase approximately 15% of our common stock on a fully diluted basis, and up
to $25 million aggregate principal amount of new notes for all old notes that
are outstanding after the asset sale offer and are properly tendered at or prior
to the expiration date. As a result of the recapitalization, holders of old
notes will receive, for each $1,000 of old notes tendered in the asset sale
offer and the exchange offer, $____ in cash, ______ shares of preferred stock,
representing a liquidation preference of $____ plus the pro rata portion of the
accrued interest from July 1, 1999 through the date of the closing. warrants to
purchase ___% of our common stock on a fully diluted basis, and $_______
principal amount of new notes.

     The exchange offer is conditioned upon, among other things, at least 95% of
the outstanding principal amount of the old notes being tendered for exchange.
If 95% of the total outstanding notes are not tendered, or any other condition
to the exchange offer is not satisfied and the recapitalization is not
consummated, then we may seek implementation of the recapitalization through a
so-called "prepackaged" plan of reorganization.  See "Possible Prepackaged Plan
of Reorganization."


                                       27
<PAGE>


     In order to participate in the exchange offer, the holder of old notes must
tender all of the old notes beneficially owned by the holder.  We can extend the
exchange offer and accept all old notes tendered for exchange or amend the terms
of the exchange offer and any amendment will apply to the old notes tendered
pursuant to the exchange offer.  Additionally, we reserve the right at any time
to terminate the exchange offer and not accept for exchange any old notes
tendered for exchange.  Old notes tendered in the exchange offer may not be
withdrawn by the holder once tendered.

     We shall be deemed to have accepted validly tendered old notes when, as and
if we have given oral or written notice to the exchange/solicitation/paying
agent.  The exchange/solicitation/paying agent will act as agent for the
tendering holders of old notes and for the purposes of receiving the preferred
stock, warrants, new notes and cash from us.

     If any tendered old notes are not accepted for exchange because of an
invalid tender, the occurrence of other events set forth in this prospectus or
otherwise, certificates for any unaccepted old notes will be returned, without
expense, to the tendering holder as promptly as practicable after the exchange
expiration date.

     By agreeing to participate in the exchange and the asset sale offer, a
holder of old notes also agrees to allocate the cash, preferred stock, warrants
and new notes received for the old notes in the same manner in which we will
make this allocation. We will allocate the cash paid pursuant to the asset sale
offer to the principal amount of the old notes.  Based on this allocation
method, up to $40 million in cash will be allocated to the principal amount of
the old notes.

Exchange Expiration Date; Extensions; Waiver; Termination; Amendments

     The exchange expiration date will be October ___, 1999 at 5:00 p.m., New
York City time, unless we, in our sole discretion, extend the exchange offer, in
which case the exchange expiration date will be the latest date and time to
which the exchange offer is extended.

     In order to extend the exchange offer, we will notify the
exchange/solicitation/paying agent of any extension by oral or written notice
and will make a public announcement.  In either case we will do so prior to 9:00
a.m., New York City time, on the next business day after the previously
scheduled exchange expiration date.

     We reserve the right, in our sole discretion:

     .    to delay accepting any old notes,

     .    to extend the expiration date and accept any old notes previously
          tendered,

     .    to waive any condition to the exchange offer and accept any old notes
          tendered for exchange,

     .    to terminate the exchange offer, whether or not any of the conditions
          set forth below under "Conditions of the Exchange Offer" shall have
          been satisfied, an d

     .    to amend the terms of the exchange offer in any manner by giving oral
          or written notice of this delay, extension, termination or
          modification to the exchange/solicitation/paying agent. Any amendment
          will apply to old notes tendered.

If the exchange offer is amended in a manner determined by us to constitute a
material change, we will promptly disclose these amendments by means of a public
announcement or a supplement to this prospectus that will be distributed to the
registered holders of the old notes.

all notes tendered for exchange pursuant to the exchange offer.

Accounting Treatment

     The recapitalization transaction will be accounted for as a troubled debt
restructuring pursuant to Statement of Financial Accounting Standard No. 15 -
Accounting by Debtors and Creditors for Troubled Debt Restructurings.

     .    The face value of the old notes is $125.0 million.

     .    The carrying amount of the old notes on the financial statements
          represents the face value of the old notes adjusted for the
          unamortized original issue discount and the unamortized debt issuance
          costs of the old notes.

     .    The old notes will, in part, be purchased at face value for up to
          $40.0 million in cash and, in part, exchanged for preferred stock with
          a liquidation preference of $65.0 million plus the amount of accrued
          interest on the old notes from July 1, 1999 through the date of the
          closing of the recapitalization, warrants to purchase approximately
          15% of our common stock on a fully diluted basis and up to $25.0
          million principal amount of new notes.

     .    New notes with a face value of up to $25.0 million will be exchanged
          for the remaining carrying value of the old notes. The difference
          between the remaining carrying value of the old notes and the face
          value of the new notes will be recognized as an addition to interest
          expense over the term of the new notes. The subsequent interest
          charges will be computed using an effective interest rate which
          equates the remaining carrying value of the old notes to the present
          value of the future principle and interest payments of the new notes.

     .    The excess of the total value of the preferred stock issued over its
          $.01 per share par value will be credited to paid in capital, net of
          any issuance costs.

     .    The carrying value of any remaining original issue discount on the old
          notes will reduce the carrying value of the remaining old notes.

     .    The carrying value of any remaining costs originally incurred to issue
          the old notes will reduce the carrying value of the remaining old
          notes.

     .    The amount of any costs incurred to complete the restructuring of the
          old notes will be expensed.

The following table summarizes the accounting for this transaction, assuming
that $40.0 million in cash is used and $20.0 million in new notes are exchanged
(Dollars in thousands):

</TABLE>

                              THE ASSET SALE OFFER

     Simultaneously with the exchange offer, Kaiser will conduct an asset sale
offer pursuant to the terms of the indenture governing the old notes.  We will
offer to purchase at par up to $40 million aggregate principal amount of


                                       30
<PAGE>


old notes. We will make this asset sale offer to all holders of old notes. If
the holders of old notes accept the asset sale offer in an amount greater than
the aggregate amount we offer to purchase, we will purchase old notes tendered
on a pro rata basis. Old notes tendered in the asset sale offer may not be
withdrawn by the holder once tendered.

     The cash to be used in the asset sale offer will consist primarily of the
proceeds from our sale of our Consulting Group.  In the event we were to file
for relief under Chapter 11 of the U.S. Bankruptcy Code within 90 days, or
possibly one year, of making the payments made in the asset sale offer, the
payments may be avoidable as a preference and could be subject to recovery by a
trustee in bankruptcy, an official creditors' committee, other representatives
of our creditors, or Kaiser as a debtor in possession.  If the payments were
successfully challenged as preferences, holders either could be required to
return the funds received, together with interest at a rate determined by the
court, or could be precluded from receiving any distribution on account of the
holders' old notes.

     The asset sale offer will expire at 5:00 p.m., New York City time, on
October __, 1999.  The asset sale offer is made subject to satisfaction of all
of the conditions to the exchange offer being satisfied or waived by us and the
exchange offer not having been terminated by us.  The asset sale offer will not
be consummated unless the exchange offer also is consummated and the requisite
consents are received.


                            THE CONSENT SOLICITATION

General

     In connection with the exchange offer, we are soliciting consents from the
holders of the old notes to approve proposed amendments to the old notes
indenture.  We are also requesting holders of the old notes to deliver an
instruction to the trustee not to interfere with our recapitalization.  Consents
of holders of a majority of the outstanding aggregate principal amount of the
old notes are required to approve the proposed amendments to the old notes
indenture.  The proposed amendments will become effective only if the conditions
of the exchange offer are satisfied or waived and will become effective
immediately preceding the consummation of the exchange offer.  Both our
acceptance of the exchange offer and consummation of the asset sale offer are
contingent upon our receipt of requisite consents from holders of the old notes.
If the proposed amendments become effective with respect to the old notes
indenture, they will apply to all old notes issued under that indenture.

Proposed Amendments

     If the requisite consents are received from holders of the old notes, the
old notes indenture will be amended by eliminating substantially all of the
restrictive covenants governing the old notes.  These proposed amendments will
eliminate the following covenants and events of default in the old notes
indenture:

     .    Section 5.04 (Limitation on Additional Indebtedness)

     .    Section 5.06 (Limitations on Restricted Payments)

     .    Section 5.07 (Limitations on Restrictions on Distributions from
          Subsidiaries)

     .    Section 5.08 (Limitations on Transactions with Affiliates)

     .    Section 5.11 (Limitations on Guarantees)

     .    Section 5.12 (SEC Reports)

     A holder of old notes need not consent to the proposed amendments in order
to tender its old notes in the exchange offer.  Conversely, each holder of old
notes not tendered or accepted for exchange pursuant to the exchange offer will
be bound by the proposed amendments if they become effective regardless of
whether the holder consented to the proposed amendments.


                                       31
<PAGE>


     Upon effectiveness of the proposed amendments, a consenting holder's right
to sell or transfer the old notes will be restricted, and each consenting holder
will be required to hold their old notes in certificated form as opposed to
holding them in "street name."  See "The Solicitation-Restriction on Transfer of
Old Notes; Issuance of Certificated Notes."

     The proposed amendments will be set forth in an amended and restated
indenture substantially in the form filed as exhibit 4(j) to the registration
statement of which this prospectus forms a part.

Solicitation Expiration Date; Extensions; Amendments

     The consent solicitation will expire at 5:00 p.m., New York City time,
________ __, 1999, unless we, in our sole discretion, extend the period during
which the consent solicitation is open, in which case the solicitation
expiration date will be the latest date and time to which the consent
solicitation is extended.

     In order to extend the solicitation expiration date, we will make a public
announcement prior to 9:00 a.m., New York time, on the next business day after
the previously scheduled solicitation expiration date.

     We reserve the right, in our sole discretion,

     .    to delay accepting any consents,

     .    to extend the consent solicitation,

     .    to terminate the consent solicitation, and

     .    to amend the terms of the consent solicitation in any manner by giving
          oral or written notice of the delay, extension, termination or
          modification to the exchange/solicitation/paying agent.

If the consent solicitation is amended in a manner that we determine constitutes
an adverse change to the holders of the old notes, we will promptly disclose the
amendment by means of a public announcement or a supplement to this prospectus
that will be distributed to the registered holders of the old notes.

Waivers and Nonacceptance of Consents

     We reserve the absolute right to waive any defects or irregularities in the
furnishing of the consents.  If any consents are not accepted for any reason,
the notes to which the consent relates will be returned without expense to the
submitting holder as promptly as practicable after the expiration or termination
of the consent solicitation.

Restriction on Transfer of Old Notes; Issuance of Certificated Notes

     If the consents become effective on the solicitation expiration date, any
holder of old notes that has furnished a consent will have agreed

     .    not to transfer, sell, assign, encumber or otherwise dispose of the
          beneficial ownership of the holder's old notes, unless the holder
          provides evidence satisfactory to us that the holder's transferee,
          and, if different, the beneficial owner of the old notes so
          transferred, has agreed in writing in form and substance satisfactory
          to us that the transferred old notes are subject to the terms of the
          consent, and that the transferee, and, if different, the beneficial
          owner, has agreed to be bound by the terms of the consent, and

     .    that any old notes subject to consents that are held through DTC will
          be reissued in certificated form.


                                       32
<PAGE>


The restriction on transfer will be noted on the old notes with respect to which
consents are received and none of these old notes may be transferred unless the
holder delivers to us an opinion of counsel in form and substance satisfactory
to us in our sole discretion that the transferee has agreed to and is bound by
the proposed amendments.


                  POSSIBLE PREPACKAGED PLAN OF REORGANIZATION

     It is possible that we will receive substantial support from holders of old
notes for the recapitalization but not reach the 95% level of acceptance of the
exchange offer required as a condition of the recapitalization.  In that event,
if the level of holder approval is sufficient, we may elect to implement the
recapitalization through a so-called "prepackaged" plan of reorganization under
Chapter 11 of the Bankruptcy Code.  We would do so by filing a petition
commencing a Chapter 11 bankruptcy case and asking the Bankruptcy Court to
approve a plan of reorganization which would contain terms and conditions for
the treatment of holders of old notes which are the same as the terms and
conditions of the recapitalization.  Such a plan of reorganization would not
affect Kaiser's operations, vendors or employees.

     If we were to seek implementation of the recapitalization through a Chapter
11 plan of reorganization, no assurance can be given that the plan would meet
the requirements for confirmation under the Bankruptcy Code, even if the plan
received the required level of approval form the holders of the old notes. The
requirement for plan approval by a impaired class of creditors is the
affirmative vote of a majority in number and more than two-thirds in dollar
amount of those voting to accept or reject the plan.  If confirmed by the
Bankruptcy Court, the plan would be binding on all holders of old notes, without
regard to whether they voted in favor of the plan.

     If a holder of old notes executes the documents required to tender old
notes in the exchange offer and the asset sale offer as contemplated in this
prospectus, the tender of old notes, once delivered, may not be withdrawn, and
the executed documentation will be counted at our election, as ballots in favor
of a Chapter 11 plan as described above.  We reserve the right to commence a
Chapter 11 case before expiration of the period provided for tender of old notes
in the exchange offer and the asset sale offer and to count executed
documentation received as ballots in favor of the Chapter 11 plan.


              PROCEDURES FOR PARTICIPATING IN THE EXCHANGE OFFER,
                   ASSET SALE OFFER AND CONSENT SOLICITATION

General

     As previously discussed, the exchange offer, the asset sale offer and the
consent solicitation are interdependent.  However, you must make a separate
decision as to each applicable transaction.  The procedures for participating in
each of the transactions are substantially similar and are described below.

Procedures for Tendering Old Notes in the Exchange Offer, Tendering Old Notes in
the Asset Sale Offer and Tendering Consents in the Consent Solicitation

     The tender of a holder's old notes or the tender of consents and its
acceptance by Kaiser will constitute a binding agreement between the tendering
holder and Kaiser upon the terms and subject to the conditions set forth in this
prospectus and in the applicable letter of transmittal and consent form.  Except
as described below, a holder who wishes to tender old notes for exchange in the
exchange offer or old notes for purchase in the asset sale offer or tender
consents in the consent solicitation must transmit any tendered old notes,
together with a properly completed and duly executed letter of transmittal and
consent form, including all other documents required by the letter of


                                       33
<PAGE>


transmittal and consent form to the exchange/solicitation/paying agent at the
address set forth below in this prospectus prior to 5:00 p.m., New York City
time, on the exchange/asset sale offer/consent solicitation expiration date.
The method of delivery of old notes, letter of transmittal and consent forms and
all other required documents is at the election and risk of the holder.  If the
delivery is by mail, it is recommended that tendering holders use registered
mail, properly insured, with return receipt requested.  Instead of delivery by
mail, it is recommended that the holder use an overnight or hand delivery
service.  In all cases, sufficient time should be allowed to assure timely
delivery.

     Any financial institution that is a participant in The Depository Trust
Company's book-entry transfer facility system may make book-entry delivery of
the old notes by causing The Depository Trust Company to transfer these old
notes into the exchange/solicitation/paying agent's account in accordance with
The Depository Trust Company's procedures for this transfer.  In connection with
a book-entry transfer, a letter of transmittal and consent form need not be
transmitted to the exchange/solicitation/paying agent, provided that the book-
entry transfer procedure is completed prior to 5:00 p.m., New York City time, on
the exchange/asset sale offer/consent solicitation expiration date.

     Each signature on a letter of transmittal and consent form or a notice of
revocation, as the case may be, must be guaranteed except that they do not need
to be guaranteed if the old notes surrendered for exchange are tendered:

     .    by a registered holder of the old notes who has not completed either
          the box entitled "Special Issuance Instructions" or the box entitled
          "Special Delivery Instructions" in the letter of transmittal and
          consent form, or

     .    by an eligible institution.

In the event that a signature on a letter of transmittal and consent form or a
notice of revocation, as the case may be, is required to be guaranteed, this
guarantee must be by a firm which is a member of a registered national
securities exchange or the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the United
States or otherwise be an "eligible guarantor institution" within the meaning of
Rule 17Ad-15 under the Securities Exchange Act of 1934.  If the letter of
transmittal and consent form is signed by a person other than the registered
holder of the old notes, the tendered old notes and consents must either

     .    be endorsed by the registered holder, with the signature guaranteed by
          an eligible institution, or

     .    be accompanied by a proxy, in a form determined to be satisfactory by
          us, in our sole discretion, duly executed by the registered holder,
          with the signature guaranteed by an eligible institution.

     All questions concerning the validity, form, eligibility, including time of
receipt, acceptance, and revocation of consents, will be decided by us in our
sole discretion, which decision shall be final and binding.  We reserve the
absolute right to reject any and all old notes or consents not properly tendered
and to reject any old notes or consents which might, in our judgment or that of
our counsel, be unlawful for us to accept.  We also reserve the absolute right
to waive any defects or irregularities or conditions of the exchange offer as to
particular old notes either before or after the exchange/asset sale
offer/consent solicitation expiration date, including the right to waive the
ineligibility of any holder who seeks to tender old notes in the exchange offer,
old notes in the asset sale offer or consents in the consent solicitation,
whether or not similar defects or irregularities are waived in the case of other
holders.  Our interpretation of the terms and conditions of the exchange offer,
asset sale offer and consent solicitation, including the letter of transmittal
and its instructions, shall be final and binding on all parties.  Unless waived,
any defects or irregularities in connection with tenders of old notes for
exchange or for purchase or tenders of consents must be cured within a period of
time as we shall determine.  Kaiser, the exchange/solicitation/paying agent, or
any other person will not have any duty to give notification of defects or
irregularities with respect to tenders of old notes and consents and will not
incur any liability for failure to give this notification.  Tenders of the old
notes and consents will not be deemed to have been made until any irregularities
have been cured or waived.


                                       34
<PAGE>


     If any letter of transmittal and consent form, endorsement, proxy, power of
attorney or any other document required by the letter of transmittal and consent
form is signed by a trustee, executor, corporation or other person acting in a
fiduciary or representative capacity, this person should indicate when signing,
and, unless waived by us, must submit proper evidence satisfactory to us, in our
sole discretion, of this person's authority to act.

     Any beneficial owner of old notes whose notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and who wants
to tender old notes in the exchange offer or in the asset sale offer or tender
consents in the consent solicitation, should contact the registered holder
promptly and instruct the registered holder to tender on the beneficial owner's
behalf.  If a beneficial owner wishes to tender directly, the beneficial owner
must, prior to completing and executing the letter of transmittal and consent
form and tendering old notes and consents, make appropriate arrangements to
register ownership of the notes in the beneficial owner's name.  Beneficial
owners should be aware that the transfer of registered ownership may take
considerable time.

Guaranteed Delivery Procedures

     Holders who wish to tender their old notes and

     .    whose old notes are not immediately available or

     .    who cannot deliver their old notes or any other documents required by
          the letter of transmittal and consent form to the
          exchange/solicitation/paying agent prior to the exchange/asset sale
          offer/consent solicitation expiration date or complete the procedure
          for book-entry transfer on a timely basis,

may tender their old notes according to the guaranteed delivery procedures
described in the letter of transmittal and consent form.  Pursuant to these
procedures:

     .    the tender must be made by or through an eligible institution and a
          notice of guaranteed delivery, as defined in the letter of transmittal
          and consent form, must be signed by the holder,

     .    on or prior to the exchange/asset sale offer/consent solicitation
          expiration date, the exchange/solicitation/paying agent must have
          received from the holder and the eligible institution a properly
          completed and duly executed notice of guaranteed delivery by facsimile
          transmission, mail or hand delivery setting forth the name and address
          of the holder, the certificate number or numbers of the tendered old
          notes, and the principal amount of tendered old notes, stating that
          the tender is being made and guaranteeing that, within three business
          days after the date of delivery of the notice of guaranteed delivery,
          the tendered old notes, a duly executed letter of transmittal and
          consent form and any other required documents will be deposited by the
          eligible institution with the exchange/solicitation/paying agent, and

     .    the properly completed and executed documents required by the letter
          of transmittal and the tendered old notes in proper form for transfer,
          or confirmation of a book-entry transfer of these old notes into the
          exchange/solicitation/paying agent's account at DTC, must be received
          by the exchange/solicitation/paying agent within three business days
          after the exchange/asset sale offer/consent solicitation expiration
          date.

Any holder who wishes to tender old notes pursuant to the guaranteed delivery
procedures described above must ensure that the exchange/solicitation/paying
agent receives the notice of guaranteed delivery and letter of transmittal
relating to these old notes prior to 5:00 p.m., New York City time, on the
exchange/asset sale offer/consent solicitation expiration date.


                                       35

Acceptance of Old Notes for Exchange or Purchase and Acceptance of Consents;
Delivery of Preferred Stock, Warrants and New Notes

     Upon satisfaction or waiver of all the conditions to the exchange offer,
Kaiser will accept any and all old notes that are properly tendered in the
exchange offer, old notes properly tendered in the asset sale offer and consents
properly tendered in the consent solicitation prior to 5:00 p.m., New York City
time, on the exchange/asset sale offer/consent solicitation expiration date. The
preferred stock, warrants and new notes issued pursuant to the exchange offer
will be delivered promptly after acceptance of the old notes. For purposes of
the exchange offer, we will be deemed to have accepted validly tendered old
notes, when, as, and if we have given oral followed by written notice to the
exchange/solicitation/paying agent. Immediately prior to consummation of the
exchange offer, we will consummate the asset sale offer and purchase for cash at
par on a pro rata basis from the holders of old notes who elect to participate
an aggregate of up to $40 million principal amount of old notes.

Revocation of Consents

     We will process all properly completed and executed letters of transmittal
and consent forms we receive, unless we receive from a holder a properly
completed and duly executed notice of revocation at any time prior to the
exchange/asset sale offer/consent solicitation expiration date.  Until the
exchange/asset sale offer/consent solicitation expiration date, any holder may
revoke a consent as to any or all old notes if we receive notice of revocation.

The Exchange/Solicitation/Paying Agent; Assistance

     The Bank of New York is the exchange/solicitation/paying agent.  All
tendered old notes and consents, executed letters of transmittal and consent
forms and other related documents should be directed to the
exchange/solicitation/paying agent.  Questions and requests for assistance and
requests for additional copies of the prospectus, a letter of transmittal and
other related documents should be addressed to the exchange/solicitation/paying
agent as follows:

Financial Advisor to Kaiser

     We have engaged Jefferies & Company, Inc. to provide financial advisory
services to us in connection with the proposed recapitalization.  As part of
such services, employees of Jefferies may solicit, on our behalf, holders of old
notes to tender their old notes in the exchange offer and the asset sale offer
and to deliver their consent to the proposed amendments to the indenture
governing the old notes.  As consideration for providing these services, we have
agreed to pay Jefferies certain fees, to reimburse its reasonable out-of-pocket
expenses and to indemnify it against liabilities, including liabilities they may
incur under the Securities Act of 1933 or the Securities Exchange Act of 1934.

Fees and Expenses

     In addition to the fees and expenses payable to Jefferies that are
described above, we will pay all other fees and expenses incurred in connection
with the recapitalization, including each of the following:


                                       36
<PAGE>


     .    fees and disbursements of legal counsel and a financial advisor
          retained by the ad hoc committee of holders of old notes formed to
          participate with our representatives in the determination of the terms
          of the recapitalization,

     .    fees and disbursements of our counsel and independent certified public
          accountants,

     .    SEC registration and NYSE listing fees, and

     .    customary fees and out-of-pocket expenses incurred by the
          exchange/solicitation/paying agent for their services in
          connection with the recapitalization.

     We will pay all transfer taxes, if any, applicable to the exchange of old
notes pursuant to the exchange offer.  If, however, a transfer tax is imposed
for any reason other than the exchange of old notes pursuant to the exchange
offer, then the amount of the transfer taxes, whether imposed on the registered
holder or any other persons, will be payable by the tendering holder.  If
satisfactory evidence of payment of these taxes or exemption is not submitted
with the letter of transmittal and consent form, the amount of these transfer
taxes will be billed directly to the tendering holder.


                                    BUSINESS

     Kaiser is a global provider of engineering, construction management, and
project and program management services.  Kaiser also owns a 50% interest in
Kaiser-Hill Company, LLC, which serves as the integrated management contractor
at the U.S. Department of Energy's Rocky Flats Environmental Technology Site.

Overview of Services and Markets

     Kaiser's activities are focused on serving clients in five major lines of
business: transit and transportation; alumina/aluminum; facilities engineering
and management, including wastewater treatment; iron and steel; and
microelectronics and clean technology.

     Transit and Transportation - Kaiser's transit and transportation services
support the planning, design, engineering, and construction of heavy- and light-
rail transit systems, high-speed rail, peoplemovers, bus systems, highways and
bridges, and airport improvements.  We are developing state-of-the- art transit
systems for 20 cities worldwide and designing major highway projects throughout
the United States and in selected international markets.  Domestic growth is
driven by the Federal Transportation Equity Act for the 21st Century.  Passed in
July 1998, the bill authorized $217 billion of spending during the next six
years in transit and highway programs.  Significant opportunities also exist
internationally as developing countries seek to improve their transit systems.
Current projects include transit systems in Seattle, Orlando, Los Angeles, the
Philippines, and Turkey; an intercity freight and passenger rail line in
Portugal; and multi-million dollar highway and bridge improvements in
California, Florida, Massachusetts, and Oklahoma.

     Alumina/Aluminum - Kaiser provides design and construction services for
expansion and modernization of some of the world's largest alumina and aluminum
facilities in locations from Kentucky to the Middle East and Australia.  Our
areas of expertise include bauxite mining and handling; alumina refining;
aluminum reduction; and fabrication and rolling.  Domestic opportunities involve
maintaining and retrofitting existing plants and replacing aging production
capacity with newer, more efficient, and environmentally responsible facilities.
Outside of the United States, there will be greater focus on building new
facilities.  Current projects include detailed design engineering, procurement,
and construction management for the expansion of a $500 million alumina refinery
in Western Australia, and engineering and design services for an aluminum
expansion project in the mid-western United States.

     Facilities and Water/Wastewater  - Kaiser provides engineering services to
public- and private-sector clients who need to modernize or maintain facilities;
design and build new capacity for the future; or improve


                                       37
<PAGE>


existing operations and environmental conditions. Future growth in this area of
activity will be based in part on the trend toward outsourcing by both private-
and public-sector clients. Kaiser's largest project of this type involves
serving, through Kaiser-Hill Company, LLC, as the integrating management
contractor at the DOE Rocky Flats site, a former nuclear weapons production
facility near Denver, Colorado. In another significant project, Kaiser serves as
construction manager for the $3.4 billion Boston Harbor cleanup project that is
currently scheduled to continue through December 31, 2002.

     Iron and Steel - Kaiser supports the iron and steel industry by providing
traditional services such as engineering, design, and project and construction
management for plant expansions, modernizations, and greenfield development.
Kaiser is the sole U.S. domestic designer and builder of coke ovens and coke
oven machinery, and is active in the development of mini-mills as an
alternative, cost-effective method of making steel.  For example, we are
providing turnkey engineering and construction services for the new $262 million
thin-slab casting mini-mill project for Nova Hut, a.s. in Ostrava, Czech
Republic.

     Microelectronics and Clean Technology - Kaiser also provides design/build
services for the microelectronics, semiconductor, biotechnology, and
telecommunication industries.  We have constructed or remodeled over seven
million square feet of manufacturing, office, and other facilities, including
more than 500,000 square feet of cleanrooms, from class 1 to class 10,000.
Following a contraction over the past several years, this market is expected to
experience growth over the next two years, driven primarily by the automotive
industry and advanced technology manufacturers' needs for increased
manufacturing capacity and capabilities.  A major project is the $219 million
semiconductor facility for Motorola in Arizona.

     Kaiser-Hill Company, LLC is equally owned by Kaiser and CH2M Hill Companies
Ltd.; Kaiser designates a majority of the members of Kaiser-Hill's Board of
Managers.  The scope of Kaiser-Hill's contract with the DOE includes all
elements of daily and long-term operation of the site, including stabilizing and
safely storing more than 14 tons of plutonium, cleaning up areas contaminated
with hazardous and radioactive waste, and restoring much of the 6,000-acre site
for future use by the public.  Kaiser-Hill's contract with the DOE currently
expires in September 2000.  On July 30, 1999, the DOE announced that it intends
to negotiate with Kaiser-Hill for a new contract for services through the
closure of the Rocky Flats site in 2006.  Such negotiations are expected to
begin in early October.  The DOE has stated that if a new contract has not been
entered into by November 30, 1999, it intends to conduct a competition for the
new contract.  We can provide no assurance as to Kaiser-Hill's ability to
compete for or win a new contract if Kaiser-Hill is unable to enter into a new
contract through negotiations.

General Information about Kaiser

     Competition and Contract Award Process

     The market for Kaiser's services is highly competitive.  Kaiser competes
with many other engineering and construction, program and project management
services firms ranging from small firms to large multinational firms having
substantially greater financial, management and marketing resources than Kaiser.
Other competitive factors include quality of services, technical qualifications,
reputation, geographic presence, price, and the availability of key professional
personnel.

     Private-Sector Work.  Competition for private-sector work generally is
based on several factors, including quality of work, reputation, price and
marketing approach.  Kaiser's objective is to establish and maintain a strong
competitive position in its areas of operations by adhering to its basic
philosophy of delivering high-quality work in a timely fashion within its
clients' budget constraints.

     Public-Sector Work.  Most of Kaiser's contracts with public-sector clients
are awarded through a competitive bidding process that places no limit on the
number or type of offerors.  The process usually begins with a government
request for proposals that delineates the size and scope of the proposed
contract.  Proposals are evaluated by the government on the basis of technical
merit, including responses to mandatory solicitation provisions, corporate and
personnel qualifications, experience, and cost.  Kaiser believes that its
experience and ongoing work strengthen its technical qualifications and,
thereby, enhance its ability to compete successfully for future government work.


                                       38
<PAGE>


     Teaming Arrangements and Joint Ventures.  In both the private and public
sectors, Kaiser, acting either as a prime contractor or as a subcontractor, may
join with other firms to form a team or a joint venture that competes for a
single contract or submits a single proposal.  Because a team of firms or a
joint venture almost always can offer a stronger set of qualifications than any
firm standing alone, these arrangements often are very important to the success
of a particular competition or proposal.  Kaiser maintains a large network of
business relationships with other companies and has drawn repeatedly upon these
relationships to form winning teams.

     Contract Structure.  Kaiser operates under a number of different types of
contract structures with its private- and public-sector clients, the most common
of which are cost plus and fixed price.  Under cost plus contracts, Kaiser's
costs are reimbursed with a fee, either fixed or percentage of cost, and/or an
incentive or award fee offered to provide inducement for effective project
management.  A variation of cost plus contracts are time-and-materials contracts
under which Kaiser is paid at a specified fixed hourly rate for direct labor
hours worked.  Under fixed price contracts, Kaiser is paid a predetermined
amount for all services provided as detailed in the design and performance
specifications agreed to at the project's inception, and under which Kaiser
retains more performance risk than under cost plus contracts.  While these fixed
price contracts can result in higher profit margins, they also can be costly if
Kaiser experiences cost overruns that are not recoverable from the client.

     Customers

     Kaiser's domestic clients include the DOE and other federal departments and
agencies; major corporations in the energy, transportation, chemical, steel,
aluminum, mining, and manufacturing industries; utilities; and a variety of
state and local government agencies throughout the United States.  The DOE
accounted for approximately 54% of Kaiser's consolidated gross revenue for the
year ended December 31, 1998, approximately 56% for the year ended December 31,
1997, and approximately 69% for the year ended December 31, 1996.  The DOE
percentage will increase for fiscal 1999 since Kaiser has disposed of its EFM
and Consulting Groups and continues to consolidate in its financial statements
the results of Kaiser-Hill Company, LLC.

     Kaiser's international clients include both private firms and foreign
government agencies.  For the years ended December 31, 1998, 1997, and 1996,
foreign clients accounted for approximately 10.1%, 14.2%, and 5.8% of Kaiser's
consolidated gross revenue, respectively. Mainly due to the sales of the EFM and
Consulting Groups, the Company currently expects this percentage to increase to
approximately 35-40% in 1999.  For information concerning gross revenue,
operating income, and identifiable assets of Kaiser's business by geographic
area during 1998, see note 12 to the consolidated financial statements included
in Kaiser's 1998 Annual Report on Form 10-K for the year ended December 31,
1998, which is incorporated by reference into and delivered with this
prospectus.

     Backlog

     Backlog refers to the aggregate amount of gross contract revenue remaining
to be earned pursuant to signed contracts extending beyond one year. Kaiser
ended 1998 with $3.2 billion in contract backlog.  The reduction from $4.1
billion of backlog at December 31, 1997 is due primarily to the completion of
another year of the Kaiser-Hill Rocky Flats contract, resulting in the
conversion of approximately $632.6 million of the 1997 backlog into revenue in
1998.  The backlog of the EFM and Consulting Groups totaled $659 million and
$540 million, respectively, at December 31, 1998.  Kaiser expects to work off
42% of the $2 billion engineering and construction and Kaiser-Hill backlog
during 1999.

       Kaiser ended the second quarter of 1999 with approximately $900 million
in contract backlog for its continuing operations; $650 million for Kaiser-Hill
and $250 million for the Engineering and Construction Group.

     Kaiser believes that backlog is not a predictor of future gross or service
revenue.  Most of Kaiser's backlog relates to the Kaiser-Hill Rocky Flats
contract.  With the dispositions of the EFM and Consulting Groups, which were
involved, to a significant extent, in providing services to the Federal
government, backlog is less of an indicator of future revenue than was the case
prior to those dispositions.

     Potential Liabilities Involving Clients and Third Parties


                                       39
<PAGE>


     In performing services for its clients, Kaiser could potentially be liable
for breach of contract, personal injury, property damage, and negligence,
including improper or negligent performance or design, failure to meet
specifications, and breaches of express or implied warranties.  The damages
available to a client, should it prevail in its claims, are potentially large
and could include consequential damages.

     Under Kaiser-Hill's contract with the DOE, Kaiser-Hill is not responsible
for, and the DOE pays all costs associated with, any liability, including
without limitation, a claim involving strict or absolute liability and any civil
fine or penalty, expense, or remediation cost, but limited to those of a civil
nature, which may be incurred by, imposed on, or asserted against Kaiser-Hill
arising out of any act or failure to act, condition, or exposure which occurred
before Kaiser-Hill assumed responsibility on July 1, 1995 ("pre- existing
conditions").  To the extent the acts or omissions of Kaiser-Hill constitute
willful misconduct, lack of good faith, or failure to exercise prudent business
judgment on the part of Kaiser-Hill's managerial personnel and cause or add to
any liability, expense, or remediation cost resulting from pre- existing
conditions, Kaiser-Hill is responsible, but only for the incremental liability,
expense, or remediation caused by Kaiser-Hill.

     The Kaiser-Hill contract further provides that Kaiser-Hill will be
reimbursed for the reasonable cost of bonds and insurance allocable to the Rocky
Flats contract and for liabilities and expenses incidental to these liabilities,
including litigation costs, to third parties not compensated by insurance or
otherwise.  The exception to this reimbursement provision applies to liabilities
caused by the willful misconduct or lack of good faith of Kaiser-Hill's
managerial personnel or the failure to exercise prudent business judgment by
Kaiser-Hill's managerial personnel.

     Insurance

     Kaiser has a comprehensive risk management and insurance program that
provides a structured approach to protecting Kaiser.  Included in this program
are coverages for:

     .    general, automobile, pollution impairment, and professional liability;
     .    workers' compensation; and
     .    employers and property liability.

Kaiser believes that the insurance it maintains, including self-insurance, is in
amounts and protects against risks as is customarily maintained by similar
businesses operating in comparable markets.  At this time, Kaiser expects to
continue to be able to obtain insurance in amounts generally available to firms
in its industry.  There can be no assurance that this situation will continue,
and if insurance of these types is not available, it could have a material
adverse effect on Kaiser.

     Kaiser has pollution insurance coverage on a claims-made basis, in amounts
and on terms that are economically reasonable, against possible liabilities that
may be incurred in connection with its conduct of its environmental business.
An uninsured claim arising out of Kaiser's environmental activities, however, if
successful and of sufficient magnitude, could have a material adverse effect on
Kaiser.

     Government Regulation

     In the past, Kaiser had a number of cost-reimbursement contracts with the
U.S. government, the costs of which are subject to audit by the U.S. government.
Most of these contracts were held by Kaiser's former EFM and Consulting Groups,
but Kaiser has retained many of the liabilities associated with the pre-closing
performance of these contracts.  As a result of pending audits related to fiscal
year 1986 forward, the government has asserted, among other things, that some
costs claimed as reimbursable under government contracts either were not
allowable or not allocated in accordance with federal procurement regulations.
Kaiser is actively working with the government to resolve these issues.  Kaiser
has provided for its estimate of the potential effect of issues that have been
quantified, including its estimate of disallowed costs for the periods currently
under audit and for periods not yet audited.  Many of the issues, however, have
not been quantified by the government or Kaiser, and others are


                                       40
<PAGE>


qualitative in nature, and their potential financial impact, if any, is not
quantifiable by the government or Kaiser at this time. This provision will be
reviewed periodically as discussions with the government progress.

     Kaiser may, from time to time, either individually or in conjunction with
other government contractors operating in similar types of businesses, be
involved in U.S. government investigations for alleged violations of procurement
or other federal laws and regulations.  Kaiser currently is the subject of a
number of U.S. government investigations and is cooperating with the responsible
government agencies involved.  No charges presently are known to have been filed
against Kaiser by these agencies.

     Employees

     As of June 30, 1999 Kaiser had approximately 3,300 employees, and Kaiser
believes that its relations with its employees are good.  Of this total,
approximately 1,700 persons are employed at Kaiser-Hill's Rocky Flats site in
Colorado.  Approximately 1,300 of the Rocky Flats employees are represented by
the United Steelworkers of America, Local 8031.  Almost all of the union
employees are contracted out to other companies working at Rocky Flats.  Kaiser
believes that its relations with the union are good.

Corporate History and Properties

     ICF Kaiser International, Inc. is a Delaware corporation incorporated in
1987 under the name American Capital and Research Corporation.  It is the
successor to ICF Incorporated, a nationwide consulting firm organized in 1969.
In 1998 Kaiser acquired the Kaiser Engineers business, which dates from 1914.
In the near future, Kaiser plans to change its name to Kaiser Group
International, Inc. and its ticker-symbol to "KSR."  The name of its principal
operating subsidiary in the United States will be changed to Kaiser Engineers,
Inc.

     Kaiser's activities are carried out through operating subsidiaries and more
than 30 offices throughout the world.  Kaiser's headquarters are located at 9300
Lee Highway, Fairfax, Virginia 22031-1207, and its telephone number is (703)
934-3600.  Kaiser's operations are organized into North American and
International regions.  The North American regional headquarters is located in
Fairfax, Virginia, and the International regional headquarters is located at
Q.V. 1 Building, George's Terrace, Perth WA 6000 Australia, telephone 61-89-366-
5366.

     Kaiser's operations are conducted in leased facilities or in facilities
provided by the Federal government or other clients.  Because Kaiser's
operations generally do not require the maintenance of unique facilities,
suitable office space is available for lease in all of the geographic areas
currently served.  Kaiser believes that adequate space to conduct its operations
will be available for the foreseeable future.  For information concerning an
investment by Kaiser in Fairfax, Virginia land and buildings where Kaiser's
headquarters are located, see notes 4 and 9 to the consolidated financial
statements included in Kaiser's 1998 Annual Report on Form 10-K for the year
ended December 31, 1998, which is incorporated by reference into and delivered
with this prospectus.

Legal Proceedings

     In the course of Kaiser's normal business activities, various claims or
charges have been asserted and litigation commenced against Kaiser arising from
or related to properties, injuries to persons, and breaches of contract, as well
as claims related to acquisitions and dispositions.  Claimed amounts may not
bear any reasonable relationship to the merits of the claim or to a final court
award.  In the opinion of management, an adequate reserve has been provided for
final judgments, if any, in excess of insurance coverage, that might be rendered
against Kaiser in the event of litigation.  See "Risk Factors" and note 7 to the
consolidated financial statements included in Kaiser's Quarterly Report on Form
10-Q for the quarter ended June 30, 1999, which is incorporated by reference
into and delivered with this prospectus for a description of certain pending
legal proceedings.

                                   MANAGEMENT

     During 1999, Kaiser implemented certain changes in its executive
management.  These changes were made in light of the changes in Kaiser's
business focus that resulted from its sale of the EFM and Consulting Groups, and
in order to manage Kaiser's operations during what is expected to be a period of
significant change, including the

                             UNITED STATES FEDERAL
                           INCOME TAX CONSIDERATIONS

     The following discussion sets forth the opinion of Squire, Sanders &
Dempsey L.L.P, counsel to Kaiser, regarding the material United States federal
income tax consequences to holders of old notes resulting from the exchange, the
cash purchase of the old notes pursuant to the asset sale offer, and the consent
solicitation.  The discussion assumes that holders hold the old notes, preferred
stock, warrants and new notes as capital assets within the meaning of Section
1221 of the Internal Revenue Code of 1986, as amended.  Further, this discussion
assumes that the old notes are treated as debt and not equity for United States
federal income tax purposes.  This discussion does not purport to deal with all
aspects of United States federal income taxation that may be relevant to holders
who may be subject to special federal income tax laws, such as dealers in
securities, financial institutions, life


                                       42
<PAGE>


insurance companies, individuals who are not citizens or residents of the United
States or corporations, partnerships or other entities that are not organized
under the laws of the United States or any political subdivision, or persons
that hold the old notes, the preferred stock, the warrants, or the new notes as
part of a hedge, conversion transaction, straddle or other risk reduction
transaction. In addition, the following discussion does not consider the effect
of any applicable foreign, state or local tax laws.

     The discussion below is based upon the current provisions of the Internal
Revenue Code, existing and proposed Treasury Regulations promulgated under the
Internal Revenue Code, rulings of the Internal Revenue Service and judicial
decisions now in effect as of the date of this prospectus.  Such authorities may
be repealed, revoked or modified, possibly with retroactive effect, so as to
result in United States federal income tax consequences different from those
described below.

     As discussed below, the exchange, together with the cash purchase of old
notes, should constitute a recapitalization under Section 368(a)(1)(E) of the
Internal Revenue Code.  However, Kaiser will not seek a ruling from the Internal
Revenue Service regarding any of the tax issues described in this discussion,
including the tax treatment of the exchange and cash purchase as a
recapitalization.  Moreover, as noted in the discussion, issues relevant to the
federal income tax consequences of some matters are factual in nature, and other
issues involve areas of law that are ambiguous or with respect to which legal
authority is lacking and as to which limited guidance is available.  It is
possible, for example, that the Internal Revenue Service may challenge the
treatment of the exchange and cash purchase of old notes as a recapitalization
and assert either that the exchange and cash purchase must be treated
independently for federal income tax purposes and/or that the exchange is a
taxable transaction because the old notes do not constitute "securities" or
because of other legal positions.  Consequently, there can be no assurance that
the Service will not challenge one or more of the tax consequences described
below.

     This discussion does not purport to deal with all aspects of United States
federal income taxation that, because of specific circumstances applicable to a
holder, might be relevant to a holder's decision to participate in the exchange,
the cash purchase of the old notes pursuant to the asset sale offer, or the
consent solicitation or to the ownership and disposition of the preferred stock,
warrants and new notes.  Holders are urged to consult their tax advisors
concerning the United States federal income tax considerations that may be
specific to them as well as any tax consequences arising under the laws of any
other taxing jurisdiction.

Tax Consequences to the Holders Upon the Exchange and Cash Purchase of Old Notes

     Importance of Whether the Old Notes Constitute "Securities."  The federal
income tax consequences to the holders of old notes will depend, in part, on
whether the old notes constitute "securities" for federal income tax purposes.
The term "security" is not defined in the Internal Revenue Code or in the
Treasury Regulations and has not been clearly defined in court decisions.
Although there are a number of factors that may affect the determination of
whether a debt instrument is a "security," one of the most important factors is
the original term of the instrument, or the length of time between the issuance
of the instrument and its maturity.  In general, instruments with an original
term of more than ten years are likely to be treated as "securities," and
instruments with an original term of less than five years are unlikely to be
treated as "securities."  Because the term of the old notes is between five and
ten years, it is impossible to be certain regarding the treatment of such old
notes as "securities."  Nevertheless, although the issue is not free from doubt,
the old notes should constitute "securities" for federal income tax purposes.
BECAUSE THE ISSUE IS UNCERTAIN, HOLDERS ARE URGED TO CONSULT WITH THEIR TAX
ADVISORS AS TO THE PROPER TREATMENT OF THE OLD NOTES.

     Treatment of the Exchange and the Purchase of Old Notes as a
Recapitalization Under Internal Revenue Code Section 368.  Assuming that the old
notes are treated as securities, the exchange of old notes for preferred stock,
warrants and new notes, and the purchase by Kaiser of old notes for cash, should
be treated together as a recapitalization under Section 368(a)(1)(E) of the
Internal Revenue Code.  The new notes likely will not be considered "securities"
for federal income tax purposes.  If the exchange and purchase together qualify
as a recapitalization, a holder that both exchanges old notes for preferred
stock, warrants and new notes and sells old notes pursuant to the asset sale
offer by Kaiser will recognize gain, but not loss, generally equal to the lesser
of:


                                       43
<PAGE>


     .    the amount of cash received in the purchase of old notes and the fair
          market value of new notes received in the exchange, or

     .    the amount of gain realized in the purchase and exchange, which is the
          excess, if any, of

          .    the sum of the cash received in the purchase of old notes plus
               the total of the fair market values of the preferred stock,
               warrants and new notes received in the exchange over

          .    the holder's aggregate adjusted tax basis in the old notes
               purchased and exchanged.

A holder that only exchanges old notes for preferred stock, warrants and new
notes will recognize gain, but not loss, generally equal to the lesser of:

     .    the fair market value of the new notes received in the exchange, or

     .    the amount of gain realized in the exchange, which is the excess, if
          any, of

          .    the total of the fair market values of the preferred stock,
               warrants and new notes received in the exchange over

          .    the holder's aggregate adjusted tax basis in the old notes
               exchanged.

     Any recognized gain will generally be treated as capital gain and will be
long-term capital gain if the holder held the old notes for more than 12 months.
If, however, a holder purchased the old notes at a market discount within the
meaning of Internal Revenue Code Section 1278, any gain recognized will be
treated as ordinary income to the extent of the accrued market discount on the
old notes.

     A holder who participates in the purchase and exchange will generally have
a tax basis in the preferred stock and warrants received in the exchange equal
to the holder's adjusted tax basis in the old notes purchased and exchanged,
decreased by the sum of the amount of cash received in the purchase and the fair
market value of the new notes received in the exchange, and increased by the
amount of gain, if any, recognized in the purchase and exchange.  That basis
will be allocated between the preferred stock and warrants in proportion to
their relative fair market values.  A holder will have a basis in the new notes
equal to their fair market value at the time of the exchange.  A holder's
holding period for the preferred stock and warrants will include the holding
period for the old notes exchanged.  A holder's holding period for the new notes
will begin on the day following the day of the exchange.

     A holder who participates only in the exchange will generally have a tax
basis in the preferred stock and warrants received in the exchange equal to the
holder's adjusted tax basis in the old notes exchanged, decreased by the fair
market value of the new notes received in the exchange, and increased by the
amount of gain, if any, recognized in the exchange.  That basis will be
allocated between the preferred stock and warrants in proportion to their
relative fair market values on the date of the exchange.  A holder will have a
basis in the new notes equal to their fair market value at the time of the
exchange.  A holder's holding period for the preferred stock and warrants will
include the holding period for the old notes exchanged.  A holder's holding
period for the new notes will begin on the day following the day of the
exchange.

     Treatment of the Exchange as a Recapitalization Under Internal Revenue Code
Section 368 But Treatment of the Purchase of Old Notes as a Separate
Transaction.  It is possible that the Internal Revenue Service could
successfully claim that the purchase of old notes and the exchange must be
treated independently of each other for federal income tax purposes.  In that
event, if the exchange qualifies as a recapitalization, a holder that exchanges
old notes for preferred stock, warrants and new notes will recognize gain, but
not loss, generally equal to the lesser of:

     .    the fair market value of the new notes received in the exchange, or


                                       44
<PAGE>


     .    the amount of gain realized in the exchange, which is the excess, if
          any, of

          .    the total of the fair market values of the preferred stock,
               warrants and new notes received in the exchange over

          .    the holder's aggregate adjusted tax basis in the old notes
               exchanged.

The holder's aggregate tax basis in the preferred stock and warrants received in
the exchange will generally be equal to the holder's adjusted tax basis in the
old notes exchanged, decreased by the fair market value of the new notes
received in the exchange, and increased by the amount of gain, if any,
recognized in the exchange.  That basis will be allocated between the preferred
stock and warrants in proportion to their relative fair market values on the
date of the exchange.  A holder will have a basis in the new notes equal to
their fair market value at the time of the exchange.  A holder's holding period
for the preferred stock and warrants will include the holding period for the old
notes exchanged.  A holder's holding period for the new notes will begin on the
day following the day of the exchange.

     Further, if the Internal Revenue Service successfully claims that the
purchase of old notes and the exchange must be treated independently of each
other for federal income tax purposes, a holder whose old notes are purchased
will recognize an amount of gain or loss generally equal to the amount of cash
received minus the holder's adjusted tax basis in the old notes purchased.
Subject to the market discount rules discussed above, any recognized gain or
loss would generally be treated as capital gain or loss and would be long-term
capital gain or loss if the holder held the old notes for more than 12 months.

     Treatment of the Exchange as a Taxable Exchange.  Assuming that the old
notes constitute "securities" for federal income tax purposes, the purchase of
old notes and the exchange should constitute a recapitalization under Internal
Revenue Code Section 368 resulting in the federal income tax consequences
discussed above under "Treatment of the Exchange and Purchase of Old Notes as a
Recapitalization Under Internal Revenue Code Section 368."  However, Kaiser will
not seek a ruling from the Internal Revenue Service regarding the treatment of
the old notes as "securities," and it is possible that the Internal Revenue
Service may challenge this treatment.  If this challenge were successful, the
exchange would be considered a taxable exchange with the likely result that a
holder would recognize gain or loss upon the exchange, in addition to any gain
or loss recognized on the purchase, generally equal to the difference between:

     .    the sum of the fair market values of the preferred stock, warrants and
          new notes received in the exchange, and

     .    the holder's adjusted tax basis in the old notes exchanged.

     Subject to the market discount rules discussed above, any recognized gain
or loss would generally be treated as capital gain or loss and would be long-
term capital gain or loss if the holder held the old notes for more than 12
months.  A holder's tax basis in the preferred stock, warrants and new notes
would equal their respective fair market values, and their holding period would
begin on the day following the day of the exchange.

     Payment of Accrued Interest on Old Notes.  Regardless of the treatment of
the purchase and exchange as described above, a holder, in addition to any gain
recognized as a result of the purchase and exchange, will recognize ordinary
income attributable to any consideration received as payment for accrued
interest on the old notes that was not previously included in the holder's
income.  Holders that have already included the accrued interest in income will
not recognize any additional income as a result of the consideration received as
payment for the accrued interest on the old notes.

     For federal income tax purposes, it is unclear how much, if any, of the
cash payment in the purchase and the preferred stock, warrants and new notes
issued in the exchange should be allocated to accrued interest.  Consistent with
the form of the transaction to be consummated as part of the solicitation,
Kaiser intends to take the


                                       45
<PAGE>


position for tax and accounting purposes, and for purposes of backup withholding
and information reporting, that approximately $______ of the cash paid and
$_____ in value of the preferred stock, warrants and new notes issued in the
exchange will be paid to holders as payment for accrued interest on the old
notes.

     By participating in the purchase and/or exchange, a holder agrees to
allocate the cash, preferred stock, warrants and new notes received for the
principal amount of the old notes and accrued and unpaid interest in the same
manner in which Kaiser will make this allocation.  It is possible, however, that
the Internal Revenue Service may challenge this allocation and require a holder
to allocate the cash, preferred stock, warrants and new notes received first to
accrued and unpaid interest on all of the old notes held by the holder, and
allocate any remaining cash, preferred stock, warrants and new notes to the
principal amount of the old notes.  This will have the effect of causing a cash
basis holder to report a greater portion of the accrued interest on its old
notes as ordinary income.  In calculating the amount of gain or loss recognized
on the purchase or exchange as described above, the amount of cash, preferred
stock, warrants and new notes allocated to accrued interest will not be taken
into account.

     Economic Accrual of Redemption Premium on Preferred Stock.  The preferred
stock will be redeemable, in whole or in part, at the option of Kaiser at any
time following the exchange.  In addition, upon the occurrence of a change of
control, Kaiser is required to offer to purchase the preferred stock.  The issue
price of such preferred stock is generally the stock's fair market value as of
the issue date.  For federal income tax purposes, if a corporation issues
preferred stock that may be redeemed at a price that is more than a de minimis
amount higher than its issue price, the difference is treated as a "redemption
premium" that is taxable to the holder on an annual economic accrual basis,
which is commonly referred to as a constant-yield-to-maturity basis.  In such
event, the holder's tax basis in the preferred stock will increase by the amount
included in the holder's gross income as accrued redemption premium.

     Where as in this case the preferred stock is optionally redeemable by
Kaiser at any time, is subject to a mandatory purchase offer upon a change of
control, and is subject to mandatory redemption on December 31, 2004, the
determination of the redemption premium and the period over which that
redemption premium is accrued and taxable to the holder is determined based on
the date that redemption is most likely to occur, provided redemption is more
likely than not to occur at some time.  Kaiser believes that the most likely
date of redemption of the preferred stock is December 30, 2001, at which time
the preferred stock will be redeemable at 95% of its liquidation preference.
Accordingly, the redemption premium will be the excess of 95% of the liquidation
preference of the preferred stock over the fair market value of that stock on
its date of issuance.  Kaiser is required to and will provide information
relating to the accrual of redemption premium to the Internal Revenue Service
and make this information available to holders.  A holder is required to report
the accrued redemption premium for federal income tax purposes consistently with
this information unless the holder explicitly discloses to the Internal Revenue
Service that its determination of accrued redemption premium differs from that
of Kaiser.

       Original Issue Discount on New Notes.   The new notes may have "original
issue discount."  Original issue discount is the excess of the stated redemption
price at maturity of the new notes over their issue price.  The issue price of
the new notes will equal:

     .    their fair market value if the new notes are treated as traded on an
          established market within the meaning of the Treasury Regulations,

     .    the excess of the fair market value of the old notes over the fair
          market value of the preferred stock and warrants issued in the
          exchange, but only if the new notes are not treated as traded on an
          established market and the old notes, preferred stock and warrants are
          treated as so traded, or

     .    the stated principal amount of the new notes, if neither of the
          previous two alternatives applies.

     For federal income tax purposes, original issue discount that exceeds a de
minimis amount accrues to a holder of a new note over the period to maturity
based on the constant yield to maturity method, compounded semi-annually, or
over such shorter permitted compounding interval selected by the holder.  With
respect to an original holder of a new note:


                                       46
<PAGE>


     .  is includable in that holder's gross income for federal income tax
        purposes and

     .  is added to that holder's tax basis for purposes of determining gain or
        loss on the maturity, redemption, prior sale or other disposition of
        that new note.

     Disposition of Preferred Stock, Warrants, or New Notes.  A holder generally
will recognize gain or loss upon the sale, exchange, redemption or other
disposition of the preferred stock, warrants, or new notes equal to the
difference between the amount realized on the disposition and the holder's
adjusted tax basis in the preferred stock, warrants, or new notes, as
applicable.  The gain or loss recognized on such a disposition generally will be
capital gain or loss and will be long-term capital gain or loss if the holder's
holding period for the preferred stock, warrants, or new notes, as applicable,
is more than 12 months.  However, an amount of gain up to the amount of accrued
market discount, if any, on the old notes at the time of the exchange will be
treated as ordinary income, assuming the exchange was treated as a
recapitalization under Internal Revenue Code Section 368.

     Exercise of Conversion Option. A holder generally will not recognize gain
or loss upon the conversion of shares of preferred stock into shares of common
stock.  However, any common stock attributable to dividend arrearages on the
preferred stock at the time of the conversion will generally be treated as a
taxable dividend to the holder.  A holder's tax basis in the common stock will
generally equal the holder's adjusted tax basis in the preferred stock
converted.  A holder's holding period for the common stock will include the
holding period for the preferred stock converted.

     Exercise of Warrants.  A holder will not recognize gain or loss upon the
exercise of the warrants.  Following exercise of the warrants, a holder's tax
basis in any common stock for which the holder paid a cash exercise price should
equal the holder's adjusted tax basis in the warrants exercised, increased by
the exercise price.  A holder's holding period for any common stock for which
the holder paid a cash exercise price should commence on the day following the
day that the warrants are exercised.  A holder's tax basis in any common stock
acquired upon exercise of the warrants using preferred stock to pay the exercise
price should generally equal the holder's aggregate adjusted tax basis in the
preferred stock so used plus the holder's tax basis in the warrants exercised.
A holder's holding period for any common stock acquired upon exercise of the
warrants using preferred stock to pay the exercise price should include the
holder's holding period for the preferred stock so used.

Solicitation of the Consents of Holders

     Concurrently with the exchange offer, Kaiser will solicit the consents of
the holders of the old notes to remove most of the covenants in the old notes
indenture.  The federal income tax consequences to holders will depend upon
whether removal or amendment of the covenants results in a deemed exchange of
"modified" notes for the "original" notes.  Treasury Regulations promulgated
under Section 1001 of the Internal Revenue Code provide that such a deemed
exchange occurs if a "significant modification," as described in the Treasury
Regulations, in the terms of the debt instrument has occurred, taking into
account all relevant facts and circumstances.

     The Treasury Regulations provide that a modification to a debt instrument
that adds, deletes, or alters customary accounting or financial covenants is not
a significant modification giving rise to a deemed exchange.  Based on these
Regulations, the removal of the covenants from the old notes indenture will not
constitute a significant modification of the old notes.  Accordingly, the
removal of the covenants from the old notes indenture will not result in a
taxable exchange of the old notes under Internal Revenue Code Section 1001.

Backup Withholding and Information Reporting

     Under some circumstances, a holder may be subject to backup withholding at
a 31% rate on payments received in the purchase or exchange and with respect to
the preferred stock, warrants and new notes issued in the exchange.  This
withholding generally applies only if the holder:

     .  fails to furnish the holder's social security or other taxpayer
        identification number,
                                      47
<PAGE>



     .  furnishes an incorrect taxpayer identification number,

     .  is notified by the Internal Revenue Service that the holder has failed
        to report payment of interest and dividends properly and the Internal
        Revenue Service has notified Kaiser that the holder is subject to backup
        withholding, or

     .  fails, under some circumstances, to provide a certified statement,
        signed under penalties of perjury, that the taxpayer identification
        number provided is the holder's correct number and that the holder is
        not subject to backup withholding.

     Any amount withheld from a payment to a holder under the backup withholding
rules is allowable as a credit against the holder's federal income tax
liability, provided that the required information is furnished to the Internal
Revenue Service.  Some holders, such as corporations and financial institutions,
are not subject to backup withholding.  Holders should consult their tax
advisors as to their qualification for exemption from backup withholding and the
procedure for obtaining this exemption.

     Because the purchase and exchange should be treated as a recapitalization
under Internal Revenue Code Section 368, holders will be required to file
information regarding the purchase and exchange in connection with filing their
federal income tax returns for the period in which the purchase and exchange
occur.

Tax Consequences to Kaiser Upon the Purchase and Exchange of Old Notes

     Discharge of Indebtedness.  The principal amount of Kaiser's aggregate
outstanding indebtedness will be reduced upon the cash purchase and exchange of
the old notes.  Generally, the cancellation or other discharge of indebtedness
triggers ordinary income to a debtor unless payment of the liability would have
given rise to a deduction.  The amount of the discharge of indebtedness income
generally will be equal to the excess of the adjusted issue price, as defined in
Treasury Regulation Section 1.1275-1(b), of the indebtedness discharged over the
aggregate value of cash and other property, including the preferred stock,
warrants and new notes, transferred in satisfaction of the indebtedness.

     However, Kaiser may not realize taxable income from discharge of
indebtedness if the discharge of indebtedness occurs while Kaiser is
"insolvent," as defined in Internal Revenue Code Section 108(d)(3), or if the
discharge occurs while Kaiser is under the jurisdiction of a court in a
bankruptcy proceeding under title 11 of the United States Code and the discharge
of indebtedness is granted by the court or is pursuant to a plan approved by the
court.

     If the discharge occurs while Kaiser is insolvent, to the extent that the
amount of the discharge of indebtedness does not exceed the amount by which
Kaiser is insolvent, certain tax attributes, including net operating losses,
otherwise available to Kaiser will be reduced, generally by the amount that
would otherwise be included as ordinary income.  These attribute reductions will
generally have the effect of increasing Kaiser's federal income tax liability in
subsequent taxable years.  The extent, if any, to which Kaiser is insolvent is
determined for this purpose immediately before the discharge of indebtedness.

     If the discharge occurs while Kaiser is in a title 11 case, the entire
amount of the discharge (which would otherwise be included as ordinary income)
will be applied to reduce tax attributes, including net operating losses, that
would be otherwise be available to Kaiser.  These attribute reductions will
generally have the effect of increasing Kaiser's federal income tax liability in
subsequent taxable years.


                   DESCRIPTION OF CONVERTIBLE PREFERRED STOCK

     General.  We are offering 2,600,000 shares of redeemable convertible
preferred stock as part of the exchange offer.

                                      48
<PAGE>



     Liquidation Preference.  The preferred stock will have an aggregate
liquidation preference of $65 million, or $25 per share, plus accrued interest
on the old notes from July 1, 1999 through the date of the closing of the
recapitalization.  This means that, if Kaiser is liquidated, dissolved or wound
up, each holder of a share of preferred stock will be entitled to be paid the
per share liquidation preference plus the pro rata portion of that accrued
interest.  As a holder of preferred stock, you will not be entitled to any
further payment.

     If the assets remaining after distribution to holders of debt and other
obligations are insufficient to pay all of the holders of preferred stock, any
remaining assets will be distributed on a proportionate basis to the holders of
preferred stock.  In a liquidation, holders of preferred stock must be paid
before any holders of Kaiser common stock and other junior securities receive
any payments for their shares.

     Rank.  The preferred stock will rank ahead of Kaiser's common stock.  It is
not expected that there will be other classes of preferred stock immediately
after the recapitalization.  The Kaiser Board of Directors could at any time
after the recapitalization authorize the issuance of preferred stock that ranks
equal with the preferred stock.  However, it may not authorize the issuance of
preferred stock that ranks senior to the preferred stock or the issuance of
additional debt without the consent of holders of two-thirds of the preferred
stock or the unanimous consent of the directors elected by holders of the
preferred stock.

     Dividends.  Cumulative dividends on the preferred stock will be payable in
cash on a quarterly basis at an initial rate per year equal to ____% of the
liquidation preference per share.  The dividend rate on the preferred stock will
increase to 12% on December 31, 2001.

     If we fail for any reason to pay a dividend in cash in any quarter, and if
we fail to pay the delinquent dividend and the current dividend in the following
quarter, holders of the preferred stock will have the right to appoint two
additional directors for the two dividends missed and one additional director if
any future dividend payment is missed, up to a maximum of three additional
directors. The size of our Board of Directors will be expanded accordingly.
Unpaid dividends will accumulate as additional dividends at 12% per year, which
amount will be added to the liquidation preference.

     Conversion. The preferred stock will be convertible into our common stock
at the option of the holder, subject to prior notice of redemption, at any time
on or after December 31, 2001. The number of shares of common stock into which
each share of preferred stock will be converted will be determined by reference
to the average closing price of our common stock for the 20 consecutive trading
days preceding the conversion election.

     Redemption. We will have the option to redeem the preferred stock, in
whole or in part, following the consummation of the exchange offer at:

     .  90% of the liquidation preference until June 30, 2001,

     .  95% of the liquidation preference from June 30, 2001 to December 31,
        2001, and

     .  100% of the liquidation preference from and after December 31, 2001,

plus in each case accumulated and unpaid dividends.

     If we fail to redeem the preferred stock on or before December 31, 2004,
the preferred stock will become immediately convertible into a number of
shares of common stock determined by reference to $.01 per share, the holders of
the preferred stock will be entitled to appoint two additional directors, and
the dividend rate will immediately increase to 14%.

     Change of Control Offer.  We must offer to repurchase the preferred stock
at 101% of the liquidation preference plus accumulated and unpaid dividends.  If
we fail to make the offer, the preferred stock will become immediately
convertible into a number of shares of common stock determined by reference to
$.01 per share, the

                                      49
<PAGE>



holders of the preferred stock will be entitled to appoint two additional
directors, and the dividend rate will immediately increase to 14%.

     Voting Rights.  The holders of the preferred stock generally will be
entitled to vote with holders of the common stock on all matters submitted to a
vote of our shareholders.  However, holders of preferred stock will have special
voting rights as a class for the election of directors and special voting rights
regarding mergers and liquidations in which they do not receive the liquidation
preference.  Each share of preferred stock will be entitled to one-fourth of a
vote for each preferred share until the time it is convertible, at which point
holders will be entitled to the number of votes corresponding to the number of
shares into which the preferred stock may be converted.  Prior to conversion and
assuming a proposed reverse split of the common stock is implemented, the
preferred stock will represent approximately 12% of the total voting power of
the common and preferred stock.  If Kaiser or any of its affiliates holds any
preferred stock, they will not be entitled to vote that preferred stock on these
matters.  The terms of the preferred stock may only be amended with a two-thirds
affirmative vote of the holders of preferred stock.

     If the shareholders of Kaiser do not approve the "shareholder democracy"
amendments to Kaiser's certificate of incorporation and bylaws at the 1999
Annual Meeting of Shareholders, Kaiser intends to include a proposal seeking the
approval of the "shareholder democracy" amendments on the agenda for the 2000
Annual Meeting of Shareholders.  Under the terms of the preferred stock to be
issued pursuant to the exchange offer, the holders of preferred stock will be
entitled to vote on this proposal at the 2000 Annual Meeting of Shareholders
that number of shares of common stock into which the preferred stock will be
convertible, as if the preferred stock had been converted.  See "Description of
Common Stock - Summary of Proposed Amendments to Kaiser's Certificate of
Incorporation and Bylaws."

     Protective Provisions.  Kaiser may not issue senior preferred stock or
some types of additional indebtedness without the consent of holders of two-
thirds of the preferred stock or the unanimous consent of the directors elected
by the preferred stock.

     Warrant Exercise Provision.  The preferred stock may be "useable" in the
exercise of the warrants issued in the exchange offer, at a value equal to the
liquidation preference, plus accumulated and unpaid dividends.


                            DESCRIPTION OF WARRANTS

     General.  We are offering as part of the exchange offer an aggregate of
up to 882,000 warrants, which will entitle the holders to purchase an aggregate
of approximately 15% of our common stock on a fully diluted basis.

     Exercise Price.  The exercise price of the warrants will be equal to the
average daily closing price of our common stock for the first 20 consecutive
trading days following consummation of the exchange offer.

     Fractional Interests. No fractional shares of common stock will be issued
upon exercise of the warrants. We will pay to the holder of a warrant at the
time of exercise an amount in cash equal to the current market value of any
fractional share of Kaiser common stock less a corresponding fraction of the
exercise price.

     No Voting Rights.  The holders of the warrants will have no right to vote
on matters submitted to the shareholders of Kaiser.

     No Dividends or Rights to Share in Assets.  The holders of the warrants
will have no right to receive dividends.  Also, the holders of the warrants will
not be entitled to share in the assets of Kaiser if Kaiser is liquidated,
dissolved or wound up.  If a bankruptcy or reorganization action is commenced by
or against Kaiser, a bankruptcy court may hold that unexercised warrants are
executory contracts that may be subject to rejection by Kaiser with approval of
the bankruptcy court.  If this happened, the holders of warrants may, even if
sufficient funds are available, receive nothing or a lesser amount as a result
of a bankruptcy case than they would be entitled to if they had exercised their
warrants prior to the commencement of the bankruptcy case.

                                      50
<PAGE>



     Procedures for Exercise. You can exercise a warrant by surrendering to
Kaiser the warrant certificate evidencing the warrant to be exercised, and
delivering a form of election to purchase that is properly completed together
with the exercise price. You can pay the exercise price by certified or official
bank check or wire transfer payable to Kaiser. Alternatively, a holder can
exercise a warrant by using preferred stock issued in the exchange offer, at a
value equal to the liquidation value plus accumulated and unpaid dividends.

     After a holder has surrendered warrant certificates and paid the exercise
price, Kaiser will deliver or cause to be delivered, to or upon the written
order of such holder, stock certificates representing the number of whole shares
of Kaiser common stock to which the holder is entitled.  If less than all of the
warrants evidenced by a warrant certificate are exercised, a new warrant
certificate will be issued for the remaining number of warrants.

     Warrant Expiration.  The warrants will expire on December 31, 2004 if
they have not been exercised prior to this date.

     Registration.  The warrants and the common stock underlying the warrants
will be registered under the Securities Act.

     Adjustments.  The number of shares of common stock that you can purchase
upon exercise of the warrants and the exercise price will be subject to
customary anti-dilution provisions.

     If Kaiser is subject to a merger, or all or substantially all of Kaiser's
assets are sold, each warrant will be exercisable for the right to receive the
kind and amount of securities, cash, or property to which the holder would have
been entitled if the warrants had been exercised immediately prior to the merger
or sale.

                          DESCRIPTION OF COMMON STOCK

Description of Kaiser's Capital Stock

     Kaiser's Board of Directors has submitted proposals to its shareholders
that some terms and provisions of the Amended and Restated Certificate of
Incorporation and Amended and Restated Bylaws that govern the terms, rights and
preferences of Kaiser's capital stock be amended.  If these proposals are
adopted, the rights attributable to holders of Kaiser common stock would be
altered.  A summary of the substance of those proposals is included under
"Summary of Proposed Amendments to Kaiser's Certificate of Incorporation and
Bylaws" below.  The following summary does not give effect to the adoption of
any of these proposals.

     The authorized capital stock of Kaiser consists of 90,000,000 shares of
common stock, par value $0.01 per share, and 2,000,000 shares of preferred
stock, par value $0.01 per share.  As of September 1, 1999, the outstanding
capital stock of Kaiser consisted of 24,833,890 shares of common stock and no
shares of preferred stock.

Common Stock

     Each share of common stock has one vote per share on all matters submitted
to a vote of shareholders.  Kaiser's Amended and Restated Certificate of
Incorporation provides that no action may be taken by the holders of shares of
common stock by written consent in lieu of holding a meeting of shareholders.

     Kaiser has never paid cash dividends on its common stock.  The Board of
Directors anticipates that for the foreseeable future no cash dividends will be
paid on its common stock and that Kaiser's earnings will be retained for use in
the business.  The Board of Directors determines Kaiser's common stock dividend
policy based on Kaiser's results of operations, payment of dividends on
preferred stock, if any is outstanding, financial condition, capital
requirements, and other circumstances.  Kaiser's debt agreements currently do
not permit dividends to be paid on its common stock.

     Holders of common stock have no preemptive or other rights to subscribe for
additional shares of capital stock.  Upon liquidation, dissolution, or winding
up of Kaiser, each share of common stock will share equally in assets legally
available for distribution to shareholders.

                                      51
<PAGE>



     The transfer agent and registrar for the common stock is First Chicago
Trust Company of New York, 14 Wall Street, Mail Suite 4680, New York, New York
10005.  The shareholder relations telephone number at First Chicago is (201)
324-0498, and the First Chicago Web site address is http://www.fctc.com.

     Since September 14, 1993, the common stock has been traded on the New York
Stock Exchange under the symbol "ICF."  From December 14, 1989, to September 13,
1993, the common stock was traded on the Nasdaq National Market.  The number of
holders of record of Kaiser common stock was 1,501 as of September 1, 1999.  On
September 1, 1999, the closing price per share of Kaiser common stock on the
NYSE was $0.50.  Included in Kaiser's Annual Report on Form 10-K for the year
ended December 31, 1998, which is incorporated by reference into and delivered
with this prospectus, is information concerning the high and low sales prices of
Kaiser common stock during each of the fiscal quarters during 1997 and 1998.
The table below sets forth this price information, as reported by NYSE, for each
of the quarterly periods ended since December 31, 1998.

                                              High    Low
                                             ------  -----
      1999
- -----------------
First Quarter                                $1.500  $.813
Second Quarter                               $ .813  $.250
Third Quarter (through September 1, 1999)    $ .500  $.406

Preferred Stock

     Preferred stock is available for issuance from time to time at the
discretion of the Board of Directors of Kaiser and without shareholder approval.
No shares are currently outstanding.  For each series of preferred stock it
establishes, the Board of Directors has authority to prescribe the number of
shares in that series and the dividend rate.  In addition, the Board of
Directors has authority to prescribe the voting rights, conversion privileges,
redemption, sinking fund provisions and liquidation rights, if any, and any
other rights, preferences and limitations of the particular series.  The
issuance of preferred stock could decrease the amount of earnings and assets
available for distribution to the holders of common stock or adversely affect
the rights and powers, including voting rights, of the holders of common stock.
Additionally, the issuance of preferred stock could have the effect of delaying,
deferring or preventing a change in control of Kaiser without further action by
the shareholders.  Kaiser's debt agreements currently do not permit dividends to
be paid on its preferred stock if any shares of preferred stock were to be
issued.

Senior Debt Warrants Issued in 1996

     A total of 105,000 Senior Debt Warrants were issued by Kaiser under a
warrant agreement dated as of December 23, 1996, between Kaiser and The Bank of
New York, a New York banking corporation, as warrant agent.  Each 1996 senior
warrant entitles the holder to acquire one share of common stock of Kaiser, upon
payment of the exercise price of $2.30, subject to adjustment as described
below.  All outstanding 1996 Warrants terminate and become void on December 31,
1999.  The 1996 Warrants are subject to the terms contained in the 1996 Warrant
Agreement; capitalized terms that are not otherwise defined below are used as
defined in the 1996 Warrant Agreement.  The common stock issuable upon exercise
of the 1996 Warrants has been registered with the Securities and Exchange
Commission and listed on the New York Stock Exchange.

     Non-Surviving Combination.  If Kaiser proposes to enter into a transaction
     -------------------------
that would constitute a Non-Surviving Combination if consummated, Kaiser must
give written notice to the holders promptly after an agreement is reached with
respect to the Non-Surviving Combination but in no event less than 30 days prior
to the consummation.  As used herein, a "Non-Surviving Combination" means any
merger, consolidation, or other business combination by Kaiser with one or more
persons other than a wholly owned subsidiary of Kaiser in which Kaiser is not
the survivor, or a sale of all or substantially all of the assets of Kaiser to
one or more of the other persons, if, in connection with any of the foregoing,
consideration other than consideration which includes common stock or securities
convertible into, or exercisable or exchangeable for, common stock or rights or
options to acquire common stock or other securities is distributed to holders of
common stock in exchange for all or substantially all of their equity interest
in Kaiser.


                                      52
<PAGE>



     In a Non-Surviving Combination, the surviving entity will be obligated to
distribute or pay to each holder of the 1996 Warrants, upon payment of the
purchase price prior to the expiration date, the number of shares of stock or
other securities or other property, including any cash, of the survivor that
would have been distributable or payable on account of the common stock if the
holder's 1996 Warrants had been exercised immediately prior to the Non-Surviving
Combination or, if applicable, the record date.  Following the consummation of a
Non-Surviving Combination, the 1996 Warrants will represent only the right to
receive these shares of stock or other property from the survivor upon payment
of the purchase price prior to the expiration date.

     No transaction is presently in progress or under negotiation that would
constitute a Non-Surviving Combination.

     Adjustment.  The number of shares of common stock issuable upon the
     ----------
exercise of each 1996 Warrant and the purchase price are subject to adjustment
in some circumstances, including:

     .  a dividend or distribution on Kaiser's common stock in shares of its
        common stock or a combination, subdivision, reorganization, or
        reclassification of common stock,

     .  the issuance of shares of common stock for a consideration per share
        less than the market price per share at the time of issuance,

     .  the issuance of rights, warrants, or options for the purchase of common
        stock or for the purchase of securities convertible into or exchangeable
        for common stock where the aggregate amount of consideration, taking
        into account the consideration received for the issuance of the right,
        warrant, or option plus any consideration to be received upon the
        exercise and including, in the case of a right, warrant, or option to
        purchase a convertible or exchangeable security, any consideration to be
        received upon the eventual conversion or exchange of the security for
        common stock per share of common stock received or receivable by Kaiser
        is less than the market price per share at the time of issuance of the
        right, warrant, or option,

     .  the issuance of any securities convertible into or exchangeable for
        common stock where the aggregate amount of consideration taking into
        account the consideration received for the issuance of the convertible
        or exchangeable security and the consideration to be received upon the
        conversion or exchange per share of common stock received or receivable
        by Kaiser is less than the market price per share of common stock on the
        date of issuance of the convertible or exchangeable security, and

     .  a dividend or distribution on Kaiser's common stock of cash, evidences
        of its indebtedness, other securities, or other properties or assets
        other than any cash dividend which, when aggregated with all other cash
        dividends paid in the year prior to the declaration of the cash
        dividend, does not exceed 10% of the market price per share of common
        stock on the date of this declaration.

If the terms of any of Kaiser's outstanding rights, warrants, or options for the
purchase of common stock or securities convertible into or exchangeable for
common stock change, in each case where the issuance caused an adjustment in the
terms of the 1996 Warrants, including by way of expiration of the securities but
excluding by way of antidilution provisions triggering an adjustment of the
terms upon the occurrence of an event that would cause an adjustment of the
terms of the 1996 Warrant, then the purchase price and the number of shares of
common stock issuable upon the exercise of each 1996 Warrant shall be readjusted
to take account of the change.  Notwithstanding the foregoing, no adjustment in
the purchase price or the number of shares of common stock issuable upon
exercise of 1996 Warrants will be required:

     .  until cumulative adjustments would result in an adjustment of at least
        one percent in the purchase price,

     .  for the granting, in a transaction which would otherwise trigger an
        adjustment, of any rights, warrants, or options or the issuance of any
        common stock to officers, directors, or employees of, or consultants or
        advisors to, Kaiser where the issuances are registered with the
        Securities and Exchange Commission on

                                      53
<PAGE>



        Form S-8 and do not, in the aggregate exceed five percent of the number
        of shares of common stock outstanding assuming the exercise of the
        options so granted and all rights, warrants, options, and convertible
        securities then outstanding, or

     .  the issuance of common stock pursuant to any dividend reinvestment plan
        where the purchase price of common stock is no less than 95% of the
        market price on the date of issuance.

Shareholder Rights Plan

     On January 13, 1992, the Board of Directors of Kaiser declared a dividend
distribution to shareholders of record at the close of business on January 31,
1992 of one right for each outstanding share of common stock.

     Each right entitles the registered holder of common stock to purchase from
Kaiser a unit consisting of one 1/100th of a share of Series 4 Junior Preferred
Stock, at a purchase price of $50.00 per Preferred Stock Unit, subject to
adjustment.  The rights also are subject to antidilution adjustments.  The
description of the rights is set forth in a rights agreement between Kaiser and
the rights agent.  The rights agent is First Chicago Trust Company of New York.

     A distribution date for the rights will occur upon the earlier of:

     .  10 business days following a "Stock Acquisition Date," which is the
        public announcement that a person or group of affiliated or associated
        persons has acquired, or obtained the right to acquire, beneficial
        ownership of 20% or more of the outstanding shares of common stock or

     .  10 business days following the commencement of a tender offer or
        exchange offer that would if consummated result in a person or group
        becoming an acquiring person.

On July 2, 1999, the Board of Directors amended the definition of acquiring
person within the rights agreement so that it now means any person or group of
affiliated or associated persons that has acquired, or obtained the right to
acquire, beneficial ownership of 20% or more of the outstanding shares of
Kaiser's common stock other than as a result of a "Permitted Offer."  The rights
agreement provides that a "Permitted Offer" is:

     .  a tender or exchange offer which is for all outstanding common stock and
        on terms determined to be adequate and in the best interests of Kaiser
        and its stockholders by at least a majority of the Board of Directors
        who are not officers or employees of Kaiser and who are not acquiring
        persons or affiliates, associates, nominees or representatives of an
        acquiring person,

     .  a cash tender offer for all outstanding common stock after July 31,
        2000, and

     .  the offer and acquisition of the preferred stock and warrants, including
        the underlying common stock, issuable in exchange for the old notes as
        described in this prospectus.

The rights are not exercisable until the distribution date and will expire at
the close of business on January 13, 2002, unless earlier redeemed by Kaiser as
described below.

     Until the distribution date:

     .  the rights will be evidenced by the common stock certificates and will
        be transferred with and only with these certificates and

     .  the surrender for transfer of any certificates for common stock
        outstanding will also constitute the transfer of the rights associated
        with the common stock represented by the certificate.

     In the event that, at any time following the distribution date, a person
becomes an acquiring person, then each holder of a right other than the
acquiring person will have the right to receive:

                                      54
<PAGE>



     .  upon exercise and payment of the purchase price, common stock or, in
        some circumstances, cash, property or other securities of Kaiser having
        a value equal to two times the purchase price of the right or

     .  at the discretion of the Board of Directors, upon exercise and without
        payment of the purchase price, common stock or, in some circumstances,
        cash, property or other securities of Kaiser having a value equal to the
        purchase price of the right.

     In the event that, at any time following the Stock Acquisition Date:

     .  Kaiser is acquired in a merger or other business combination transaction
        in which Kaiser is not the surviving corporation,

     .  Kaiser is the surviving corporation in a merger with any person, as
        defined in the rights agreement, and its common stock is changed into or
        exchanged for stock or other securities of any other person or cash or
        any other property, or

     .  50% or more of Kaiser's assets or earning power is sold or transferred,

each holder of a right, except rights held by an acquiring person or which
previously have been exercised as set forth above shall have the right to
receive, upon exercise, common stock of the acquiring company having a value
equal to two times the purchase price of the right.  The events set forth in
this paragraph and in the immediately preceding paragraph are referred to as the
"Triggering Events."

     As noted above, following the occurrence of any of the events described
above, all rights that are, or under some circumstances specified in the rights
agreement were, beneficially owned by any acquiring person will be null and
void.

     The purchase price payable, and the number of Preferred Stock Units or
other securities or property issuable upon exercise of the rights, are subject
to amendment from time to time to prevent dilution:

     .  in the event of a stock dividend on, or a subdivision, combination or
        reclassification of, the Series 4 Preferred Stock,

     .  if holders of the Series 4 Preferred Stock are granted rights or
        warrants to subscribe for Series 4 Preferred Stock or convertible
        securities at less than the current market price of the Series 4
        Preferred Stock, or

     .  upon the distribution to holders of the Series 4 Preferred Stock of
        evidences of indebtedness or assets, excluding regular quarterly cash
        dividends, or of subscription rights or warrants other than those
        referred to above.

     With exceptions, no adjustment in the purchase price will be required until
cumulative adjustments amount to at least one percent of the purchase price.  In
addition, to the extent that Kaiser does not have sufficient shares of common
stock issuable upon exercise of the rights following the occurrence of a
Triggering Event, Kaiser may, under some circumstances, reduce the purchase
price.  No fractional Preferred Stock Units will be issued and an adjustment in
cash will be made.

     In general, Kaiser may redeem the rights in whole, but not in part, at a
price of $0.01 per right payable in cash, common stock or other consideration
deemed appropriate by the Board of Directors, at any time until 10 business days
following the Stock Acquisition Date.  After the redemption period has expired,
Kaiser's right of redemption may be reinstated if an acquiring person reduces
its beneficial ownership to less than 10% of the outstanding shares of common
stock in a transaction or series of transactions not involving Kaiser and there
are no other acquiring persons.  Immediately upon the action of the Board of
Directors ordering redemption of the rights, and without any notice to the

                                      55
<PAGE>



holder of these rights prior to the redemption, the rights will terminate and
the only right of the holders of rights will be to receive the $0.01 redemption
price.

     Until a right is exercised, the holder will have no rights as a shareholder
of Kaiser, including, without limitation, the right to vote or to receive
dividends.

     Other than those provisions relating to the principal economic terms of the
rights, except with respect to increasing the purchase price under some
circumstances described in the rights agreement, any of the provisions of the
rights agreement may be amended by the Board of Directors of Kaiser prior to the
distribution date.  After the distribution date, the provisions of the rights
agreement may be amended by the Board in order to cure any ambiguity, to make
changes which do not adversely affect the interests of holders of rights,
excluding the interests of any acquiring person, or to shorten or lengthen any
time period under the rights agreement.  However, no amendment to adjust the
time period governing redemption shall be made when the rights are not
redeemable.

     One right will be distributed to shareholders of Kaiser for each share of
common stock owned of record by them at the close of business on the record
date.  Until the distribution date, Kaiser will issue a right with each share of
common stock so that all shares of common stock will have attached rights.

     The rights may be deemed to have anti-takeover effects.  The rights
generally may cause substantial dilution to a person or group that attempts to
acquire Kaiser under circumstances not approved by the Board of Directors of
Kaiser.  The rights should not interfere with any merger or other business
combination approved by the Board of Directors of Kaiser since the Board of
Directors may, at its option, at any time prior to the close of business on the
earlier of:

     .  the tenth business day following the Stock Acquisition Date or

     .  January 13, 2002,

redeem all but not less than all of the then outstanding rights at $0.01 per
right.

Provisions Affecting Changes of Control and Extraordinary Transactions

     In addition to the shareholder rights plan, some provisions of Kaiser's
Certificate of Incorporation and By-laws and other agreements could have the
effect of delaying, deferring, or preventing a change in control of Kaiser or
other extraordinary corporate transaction.

     Kaiser's Amended and Restated Certificate of Incorporation and By-laws
provide for classification of the Board of Directors into three classes, as
nearly equal in number as possible, with one class of directors being elected
each year for three-year terms.  Under Delaware law, members of a classified
board may be removed only for cause.  Thus, at least two years would be required
to effect a change of control in the Board of Directors, unless a shareholder
had sufficient voting power to amend or repeal the Certificate of Incorporation
and By-law provisions relating to classification of the Board of Directors.

     In addition, the Certificate of Incorporation imposes supermajority voting
requirements for some corporate transactions that apply if a majority of the
Board of Directors has not served in the positions for at least 12 months.
Under those circumstances, the approval of two-thirds of the voting power of
Kaiser's capital stock would be required in order for Kaiser to:

     .  merge with or consolidate into any other entity, other than a subsidiary
        of Kaiser,

     .  sell, lease or assign all or substantially all of the assets or
        properties of Kaiser, or

     .  amend the voting provisions of the Certificate of Incorporation.

                                      56
<PAGE>



Other Certificate of Incorporation provisions of the type referred to above
include:

     .  the denial of the right of holders of common stock to take action by
        written consent in lieu of a shareholders' meeting and

     .  the ability of the Board of Directors to determine the rights and
        preferences, including voting rights, of Kaiser's authorized but
        unissued preferred stock, and then to issue this stock.

Relevant By-law provisions include those that:

     .  require advance nomination of directors,

     .  require advance notice of business to be conducted at shareholders'
        meetings, and

     .  provide that shareholders owning at least 50% of the voting power of the
        capital stock are required to call a special meeting of shareholders.

     With the exception of the provision that authorizes the Board of Directors
to fix the terms of and issue authorized but unissued shares of preferred stock,
the approval of the holders of at least two-thirds of the voting power of
Kaiser's capital stock is required to amend, alter, or repeal, or to adopt
provisions inconsistent with, the Certificate of Incorporation and By-law
provisions described above, regardless of whether a majority of the members of
the Board of Directors has served in such positions for more than 12 months at
the time of the action.

Delaware Takeover Statute

     Section 203 of the Delaware General Corporation Law applies to Delaware
corporations with a class of voting stock listed on a national securities
exchange, authorized for quotation on an inter-dealer quotation system, or held
of record by 2,000 or more persons, and restricts transactions which may be
entered into by such a corporation and certain of its shareholders.  The
Delaware takeover statute provides, in essence, that a stockholder acquiring
more than 15% of the outstanding voting shares of a corporation subject to the
statute, but less than 85% of the shares, may not engage in certain "Business
Combinations" with the corporation for a period of three years subsequent to the
date on which the stockholder became an Interested Stockholder, unless:

     .  prior to the date the corporation's board of directors approved either
        the Business Combination or the transaction in which the stockholder
        became an Interested Stockholder or

     .  the Business Combination is approved by the corporation's board of
        directors and authorized by a vote of at least 66 2/3% of the
        outstanding voting stock of the corporation not owned by the Interested
        Stockholder.

     The Delaware takeover statute defines the term "Business Combination" to
encompass a wide variety of transactions with or caused by an Interested
Stockholder in which the Interested Stockholder receives or could receive a
benefit on other than a pro rata basis with other stockholders, including
mergers, some asset sales, some issuances of additional shares to the Interested
Stockholder, transactions with the corporation which increase the proportionate
interest of the Interested Stockholder, or transactions in which the Interested
Stockholder receives some other benefits.

Summary of Proposed Amendments to Kaiser's Certificate of Incorporation and
Bylaws

     The 1999 Annual Meeting of Shareholders of Kaiser will be held on Thursday,
November 4, 1999, at 10:00 a.m.  At the annual meeting, Kaiser's shareholders
will be asked to vote upon, among other things, proposals to:

     .  approve the issuance of shares of the preferred stock and warrants in
        connection with the exchange offer;

     .  approve a reverse stock split of Kaiser's common stock;

                                      57
<PAGE>



     .  approve the "shareholder democracy" amendments to Kaiser's certificate
        of incorporation and bylaws to eliminate the provisions of the
        certificate of incorporation and, where applicable, the bylaws that:

        .  require the affirmative vote of holders of 66 2/3% of the outstanding
           capital stock to approve certain transactions following a change in
           the majority of directors within 12 months;

        .  provide for staggered, three-year terms for members of the board of
           directors;

        .  prohibit shareholders from filling vacancies on the board of
           directors;

        .  require the affirmative vote of the holders of 66 2/3% of the
           outstanding capital stock to approve certain amendments to the
           certificate of incorporation and bylaws; and

        .  provide that shareholders owning at least 20% of the voting power of
           the outstanding capital stock could require a special meeting of
           shareholders to be called;

     .  approve an amendment to Kaiser's certificate of incorporation and bylaws
        to provide that no new shareholder rights plan, sometimes referred to as
        a "poison pill," shall be adopted without the approval of the
        shareholders;

     .  approve an amendment to Kaiser's certificate of incorporation to
        eliminate provisions related to the terms of series of preferred stock
        that are obsolete and no longer outstanding;

     .  approve an amendment to Kaiser's stock incentive plan to increase the
        number of shares of common stock available for issuance under the plan,
        to permit the transfer of options granted under the incentive plan to
        immediate family members of plan participants and to provide greater
        flexibility to Kaiser's board of directors to make future amendments to
        the plan; and

     .  approve a quasi-reorganization of Kaiser's capital accounts to eliminate
        its accumulated retained earnings deficit.

If the shareholders approve one or more of the foregoing proposals, the above
description of the common stock and shareholder rights plan would be altered
accordingly.


                            DESCRIPTION OF NEW NOTES

     The following is only a summary of the terms of the new notes.  We urge you
to read the indenture and the exhibits to the indenture for a complete
description of the terms of the new notes, copies of which are available upon
request from Kaiser.  The terms of the new notes include those stated in the
indenture and those made part of the indenture by reference to the Trust
Indenture Act of 1939 as in effect on the date of the indenture.  The
definitions of some terms used here are set forth in "Certain Definitions"
below.  The terms of the new notes may differ in material respects from the
terms of the old notes.  Holders of old notes should review this section
carefully.

General

     Kaiser will issue the new notes in partial exchange for the old notes under
an indenture between itself and Bank of New York, as trustee (the "Trustee").

     The new notes:

     .  are general unsecured obligations of Kaiser;

     .  are limited to an aggregate principal amount of up to $25 million;

     .  bear interest at the rate of 12% per annum, payable on June 30 and
        December 31 of each year, commencing on December 31, 1999, to holders of
        record at the close of business on the preceding June 15 or December 15,
        as the case may be;

     .  mature on December 31, 2002; and

     .  are issued only in registered form, without coupons, in denominations of
        $1,000 and its integral multiples.

                                      58
<PAGE>


     The new notes may be presented for registration of transfer and/or exchange
and the principal and interest on the new notes is payable at the corporate
trust office of the Trustee at 101 Barclay Street, 7 East, New York, New York
10286, or at an office or agency maintained by Kaiser in the City of New York,
New York.

Methods of Making Payments on the New Notes

     Payments are made by check mailed to the registered addresses of the
holders of record of the new notes.  Holders must surrender their notes to the
paying agent to collect principal payments.  Kaiser may require payment of a sum
sufficient to cover any transfer tax or other governmental charge payable in
connection with transfers or exchanges of the new notes.  Initially, the Trustee
acts as the paying agent and the registrar under the indenture.  Kaiser or any
of its subsidiaries subsequently may act as the paying agent and the registrar
and Kaiser may change any paying agent and any registrar without prior notice to
the holders of the new notes.

Ranking

     The new notes are senior unsecured obligations of Kaiser. The new notes
will rank equal in right of payment with all of our current and future senior
unsecured obligations. We are currently pursuing alternatives for a new secured
credit facility. The new notes would be effectively subordinated to the rights
of the lender under this credit facility.

     Kaiser's operations are conducted primarily through its subsidiaries.
Certain of our subsidiaries have guaranteed the new notes. As to these
subsidiaries, the new notes will rank as senior obligations of the subsidiary,
equal in right of payment to other current and future unsecured obligations of
the subsidiary. As to subsidiaries that have not guaranteed the new notes, the
new notes would be effectively subordinated to the current and future
obligations of those subsidiaries. As of June 30, 1999, on a pro forma basis
after giving effect to the recapitalization, the aggregate principal amount of
subsidiary indebtedness which would have effectively ranked senior to the new
notes would have been approximately [$______ million].

     Kaiser is a holding company that derives substantially all of its income
from its subsidiaries.  Kaiser must rely on dividends or other intercompany
transfers from its subsidiaries to generate the funds necessary to meet its debt
service and other obligations, including payment of principal and interest on
the new notes.  The ability of its subsidiaries to pay these dividends or other
intercompany transfers is subject to the laws of the jurisdictions where the
subsidiaries are located.  Claims of creditors against these subsidiaries
generally have priority as to the assets of the subsidiaries over Kaiser's
equity interests and the holders of Kaiser's indebtedness.  See
"Capitalization."

Optional Redemption of the New Notes

     Kaiser may choose to redeem the new notes in whole or in part, at any time,
at a redemption price equal to 100% of the aggregate principal amount of the new
notes, plus accrued and unpaid interest.

     The Trustee selects the new notes to be redeemed from among the outstanding
new notes on a pro rata basis, by lot or by any other method permitted in the
indenture, if less than all of the new notes are to be redeemed at any time.
Notice of redemption will be mailed at least 30 days but not more than 60 days
before the redemption date to each holder whose new notes are to be redeemed at
the registered address of the holder.  Interest will cease to accrue on the new
notes or portions called for redemption on and after the redemption date.

Sinking Fund

     There is no mandatory sinking fund for the new notes.

Mandatory Offers to Purchase the New Notes

     The indenture requires Kaiser to offer to purchase a portion of the
outstanding new notes under some circumstances.  See "Certain Covenants -
Limitations on Asset Sales and "Certain Covenants - Change of Control."

Certain Covenants

     Change of Control.  Upon any sale of all or substantially all of Kaiser's
assets, or the acquisition of a majority of Kaiser's equity securities by a
person or group, or Kaiser's approval of a plan of liquidation, or changes in
the majority of Kaiser's board of directors, Kaiser is obligated to repurchase
all outstanding new notes.  The purchase price equals 101% of the principal
balance of outstanding new notes, plus accrued interest to the date of purchase.

     Limitations on Additional Indebtedness.  Kaiser will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume, guarantee, extend the maturity of or otherwise become liable with
respect to any indebtedness, other than Permitted Indebtedness, unless it is
able to demonstrate that for the four quarterly periods preceding the incurrence
of this debt, its Consolidated Fixed Change Coverage Ratio, was at least 2.50 to
1.0.

                                       59
<PAGE>


     Limitations on Subsidiary Debt and Preferred Stock.  Kaiser will not permit
any of its Restricted Subsidiaries, directly or indirectly, to create, incur,
assume, guarantee, extend the maturity of or otherwise become liable with
respect to any indebtedness, which, with respect to any Restricted Subsidiary,
includes preferred stock of the Restricted Subsidiary, except for the following:

     .  guarantees by any Restricted Subsidiary of the payment of indebtedness
        incurred pursuant to the Bank Credit Agreement and in compliance with
        the covenant described under "Limitations on Additional Indebtedness"
        and with the covenant described under "Limitations on Guarantees";

     .  Indebtedness issued to and held by Kaiser or a wholly-owned Restricted
        Subsidiary, except that any subsequent issue or transfer of any Capital
        Stock that results in any wholly-owned Restricted Subsidiary ceasing to
        be a wholly-owned Restricted Subsidiary or any transfer of Indebtedness,
        other than to a wholly-owned Restricted Subsidiary, is deemed, in each
        case, to constitute the incurrence of Indebtedness by the Restricted
        Subsidiary;

     .  Indebtedness to Kaiser or any of its wholly-owned Restricted
        Subsidiaries that are engaged in Permitted Businesses in an aggregate
        amount, together with all Designated Investments made in subsidiaries
        that are not wholly-owned Restricted Subsidiaries but which are engaged
        only in Permitted Businesses and the management and operations of which
        is controlled by Kaiser, not to exceed 5% of Consolidated Tangible
        Assets; and

     .  Non-recourse indebtedness incurred by a Single Purpose Subsidiary.

     Limitations on Restricted Payments.  Kaiser will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly, make any
Restricted Payment if, at the time of a potential Restricted Payment, any of the
following conditions exist:

     .  a Default or Event of Default has occurred and is continuing or will
        occur as a consequence;

     .  Kaiser is unable to incur an additional $1.00 of Senior Indebtedness
        under the covenant described in the first sentence of the first
        paragraph under "Limitations on Additional Indebtedness"; or

     .  the amount of the Restricted Payment, when added to the aggregate amount
        of all Restricted Payments, other than those made pursuant to the
        exceptions described in the following paragraph, made after the date of
        the indenture, exceeds the sum of:

        .  50% of Kaiser's Consolidated Net Income accrued during the period
           since the date of the indenture for the new notes or, if that
           aggregate Consolidated Net Income is a deficit, minus 100% of the
           aggregate deficit; plus

        .  the net reduction in Investments attributable to Designated
           Investments by Kaiser or its subsidiaries after December 31, 1999.

     The monetary limitations described in the immediately preceding paragraph
will not prevent the following:

     .  Kaiser or any wholly-owned Restricted Subsidiary from making investments
        in subsidiaries, in an aggregate amount not to exceed $4 million,
        pursuant to contractual obligations in existence on the date of the
        indenture for the new notes or directly related to projects in existence
        on the date of the indenture for the new notes;

     .  Kaiser from paying any dividend, including dividends on dividends,
        within 60 days after the date of its declaration if this dividend could
        have been paid on the date of its declaration without violation of this
        covenant;

                                       60
<PAGE>


 .  Kaiser from purchasing or redeeming and retiring any shares of capital stock
   of Kaiser, and paying accrued and unpaid dividends on these shares at the
   time of this repurchase or redemption, in exchange for, or out of the net
   proceeds of a substantially concurrent sale, other than to a subsidiary of
   Kaiser or an employee stock ownership plan, of shares of Qualified Capital
   Stock of Kaiser;

 .  Kaiser or any subsidiary from making:

   .  investments pursuant to the provisions of employee benefit plans of Kaiser
      or any of its subsidiaries in an aggregate amount not to exceed $500,000
      in a fiscal year, or

   .  making loans to officers of Kaiser approved by a majority of the
      independent members of the Board of Directors of Kaiser, provided that the
      aggregate amount of investments and loans under this clause may not exceed
      $1 million in any fiscal year;

 .  Kaiser or any wholly-owned Restricted Subsidiary from making Designated
Investments:

   .  in subsidiaries that are not wholly-owned Restricted Subsidiaries in an
      aggregate amount, together with Indebtedness incurred by or on behalf of
      subsidiaries that are not wholly-owned Restricted Subsidiaries in
      compliance with the provisions of the third clause of the covenant
      described under "Limitations on Subsidiary Debt and Preferred Stock", not
      to exceed 5% of Consolidated Tangible Assets after December 31, 1999 or

   .  in Joint Ventures in an aggregate amount not to exceed 5% of Consolidated
      Tangible Assets after December 31, 1999, provided that:

      .  the person in whom the investment is made is engaged only in Permitted
         Businesses;

      .  Kaiser, directly or through wholly-owned Restricted Subsidiaries of
         Kaiser, controls, under an operating management agreement or otherwise,
         the day-to-day management and operation of this Person or otherwise has
         the right to exercise significant influence over the management and
         operation of this Person in all material respects, including without
         limitation the right to control or veto any material act or decision;
         and

      .  after giving effect to this Investment, the aggregate amount of
         indebtedness and investments made by Kaiser and its subsidiaries in
         this Person after December 31, 1999 does not exceed $5 million; or

 .  Kaiser or any wholly-owned Restricted Subsidiary from making Designated
   Investments in subsidiaries that are not wholly-owned Restricted Subsidiaries
   or in Joint Ventures, as long as these Designated Investments are made solely
   from:

   .  the net proceeds of a substantially concurrent sale, other than to a
      subsidiary of Kaiser or an employee stock ownership plan, of shares of
      Qualified Capital Stock of Kaiser,

   .  50% of Kaiser's Consolidated Net Income accrued during the period after
      December 31, 1999,

   .  the aggregate amount of net reductions in investments, not to exceed the
      aggregate amount of the Designated Investments, made by Kaiser or any
      Subsidiary after December 31, 1999,

 .  Kaiser or any wholly-owned Restricted Subsidiary from making Investments in
   Kaiser-Hill Company LLC or its affiliates, as long as such Investments are
   determined by Kaiser Board of Directors to be necessary or appropriate and
   that such investments are proportional to simultaneous investments made by
   the other equity owners,

                                       61
<PAGE>


   .  Kaiser from redeeming the shares of the preferred stock,

   .  Kaiser from issuing equity securities or making payments in respect of
      equity securities previously issued to former shareholders of ICT Spectrum
      Constructors, Inc.,

   .  Kaiser from making payments to redeem rights outstanding under Kaiser's
      Rights Agreement dated January 13, 1992, or

   .  Kaiser from paying dividends on the preferred stock.

   Limitations on Restrictions on Distributions from Subsidiaries. Kaiser will
not, and will not permit any of its Restricted Subsidiaries to, create or
otherwise cause or suffer to exist or become effective any consensual Payment
Restriction with respect to any of its Restricted Subsidiaries, except for the
following:

   .  any Payment Restriction contained in Existing Indebtedness or existing
      contracts to which Kaiser or any of its Restricted Subsidiaries are
      parties;

   .  any Payment Restriction under any agreement evidencing any Acquired
      Indebtedness that was permitted to be incurred pursuant to the indenture,
      as long as the Payment Restriction only applies to assets that were
      subject to these restrictions and encumbrances prior to the acquisition of
      these assets by Kaiser or its Restricted Subsidiaries; and

   .  any Payment Restriction arising in connection with Refinancing
      Indebtedness, as long as any Payment Restrictions that arise under the
      Refinancing Indebtedness are not, taken as a whole, more restricted than
      those under the agreement creating or evidencing the Indebtedness being
      refunded or refinanced.

   Limitations on Transactions with Affiliates.  Kaiser will not, and will not
permit any of its Restricted Subsidiaries to, make any loan, advance, guarantee
or capital contribution to or for the benefit of, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to or for the benefit of,
or make any Investment in, or purchase or lease any property or assets from, or
enter into or amend any contract, agreement or understanding with or for the
benefit of, any Affiliate of Kaiser or any of its subsidiaries, each of which is
an "Affiliate Transaction," except for the following:

   .  Affiliate Transactions in the ordinary course of business and consistent
      with past practice that are fair to Kaiser or the Restricted Subsidiary
      and are on terms at least as favorable as would have been obtainable at
      that time from an unaffiliated party;

   .  the Board of Directors of Kaiser or the Restricted Subsidiary pursuant to
      a Board Resolution reasonably and in good faith determines that the
      Affiliate Transaction is fair to Kaiser or the Restricted Subsidiary and
      is on terms at least as favorable as would have been obtainable at that
      time from an unaffiliated party;

   .  for any Affiliate Transaction or series of Affiliate Transactions
      involving or having a value of more than $1 million, unless a majority of
      the members of the Board of Directors of Kaiser who are not affiliated
      with any other party to the Affiliate Transaction reasonably and in good
      faith determined that the Affiliate Transaction or series of Affiliate
      Transactions is fair to Kaiser or the Restricted Subsidiary, and is on
      terms at least as favorable as would have been obtainable at that time
      from an unaffiliated party; and

   .  for any Affiliate Transaction or series of Affiliate Transactions
      involving or having a value of more than $5 million, unless Kaiser or the
      Restricted Subsidiary received an opinion from an Independent Financial
      Advisor to the effect that the financial terms of the Affiliate
      Transaction are fair to Kaiser or the Restricted Subsidiary from a
      financial point of view.

                                       62

The limitations described in the foregoing paragraph do not apply to:

   .  transactions exclusively between or among Kaiser and any of its wholly-
      owned Restricted Subsidiaries or exclusively between or among any of
      Kaiser's wholly-owned Restricted Subsidiaries, as long as these
      transactions are not otherwise prohibited by the indenture;

   .  arms-length transactions between Kaiser or any of its wholly-owned
      Restricted Subsidiaries and the other owners of any subsidiary or Joint
      Venture that is not under control of and does not have capital stock or
      indebtedness held by Kaiser or its affiliates; and

   .  reasonable compensation, indemnification and other benefits paid or made
      available to officers, directors and employees of Kaiser or any Subsidiary
      for services rendered in this Person's capacity as an officer, director or
      employee.

   Limitations on Asset Sales. Kaiser will not, and will not permit any of its
Restricted Subsidiaries to, consummate any Asset Sale unless:

   .  Kaiser or its Restricted Subsidiaries receive consideration at the time of
      the Asset Sale at least equal to the fair market value of the assets or
      Capital Stock included in the Asset Sale;

   .  the aggregate fair market value of the consideration from the Asset Sale,
      other than consideration in the form of assumption of Indebtedness of
      Kaiser or one or more of its Restricted Subsidiaries from which Kaiser or
      the Restricted Subsidiaries are released, that is not in the form of cash
      or Cash Equivalents is not, when aggregated with the fair market value of
      all other non-cash or non-Cash Equivalent consideration received by Kaiser
      and its Restricted Subsidiaries from all previous Asset Sales since the
      date of the indenture for the new notes that have not yet been converted
      into cash or Cash Equivalents, exceed 5% of Consolidated Tangible Assets
      of Kaiser at the time of the Asset Sale; and

   .  the Asset Sale has been approved by Kaiser's Board of Directors if the
      aggregate fair market value of the assets or Capital Stock to be sold in
      the Asset Sale exceeds $3 million.

   Within six months after consummation of any Asset Sale, Kaiser will, or will
cause the applicable Restricted Subsidiary to:

   .  reinvest the cash and Cash Equivalent portion of the Net Proceeds of the
      Asset Sale in a manner that would constitute a Related Business
      Investment;

   .  apply the cash and Cash Equivalent portion of the Net Proceeds of the
      Asset Sale to repay outstanding Senior Indebtedness of Kaiser or any
      Restricted Subsidiary, as long as any repayment of Indebtedness under any
      revolving credit facility or similar agreement results in a permanent
      reduction in its lending commitment in an amount equal to the principal
      amount repaid; or

   .  apply the cash and Cash Equivalent portion of the Net Proceeds of the
      Asset Sale that is neither reinvested nor applied to the repayment of
      Senior Indebtedness to the purchase of new notes tendered to Kaiser at a
      purchase price equal to 100% of its principal, plus accrued interest to
      the date of purchase, pursuant to an Asset Sale Offer to purchase made by
      Kaiser as set forth below, except that Kaiser may defer the Asset Sale
      Offer until this amount is at least $5 million.

   However, to the extent that:

   .  any or all of the Net Proceeds of any Foreign Asset Sale are prohibited or
      delayed by applicable local law from being repatriated to the United
      States, the portion of the Net Proceeds affected will not be

                                       63
<PAGE>


      required to be applied in the manner set forth in this covenant but may be
      retained by the applicable Foreign Subsidiary so long as the applicable
      local law will not permit repatriation to the United States and, once this
      repatriation of any of the affected Net Proceeds is permitted under the
      applicable local law, this repatriation will be immediately effected and
      the repatriated Net Proceeds will be applied in the manner set forth in
      this covenant; and

   .  the Board of Directors determines in good faith that repatriation of any
      or all of the Net Proceeds of any Foreign Asset Sale would have a material
      adverse tax consequence, the Net Proceeds affected may be retained by the
      applicable Foreign Subsidiary for so long as this material adverse tax
      event would continue.

   Each Asset Sale Offer must:

   .  be mailed to the record holders of the new notes as shown on the register
      of holders of new notes, with a copy to the Trustee;

   .  specify the purchase date, which must be between 30 days and 60 days from
      the date the notice is mailed and not later than 240 days after the date
      of the Asset Sale giving rise to the Asset Sale Offer; and

   .  otherwise comply with the procedures set forth in the indenture.

   Upon receiving notice of an Asset Sale Offer, holders of new notes may elect
to tender their new notes in whole or in part in integral multiples of $1,000 in
exchange for cash. To the extent holders properly tender notes in an amount
exceeding the amount of Net Proceeds used to make the Asset Sale Offer, new
notes of tendering holders will be repurchased on a pro rata basis, based on
amounts tendered.

   Kaiser will comply with the requirements of Section 14(e) under the Exchange
Act and any other securities laws and regulations to the extent these laws and
regulations are applicable in connection with the repurchase of new notes
pursuant to any Asset Sale Offer.

   Restrictions on Sale of Stock of Subsidiaries.  Kaiser may not sell or
otherwise dispose of any of the Capital Stock of any Restricted Subsidiary of
Kaiser unless:

   .  Kaiser either retains ownership of more than 50% of the common stock of
      the Restricted Subsidiary or sells all of the Capital Stock of the
      Restricted Subsidiary and the net proceeds from this sale or disposition
      are treated in a manner consistent with the treatment of Asset Sale
      proceeds; or

   .  Kaiser elects to treat the amount of its remaining investment in the
      Restricted Subsidiary that has become a Joint Venture as a result of the
      sale or disposition as an Investment in the Joint Venture subject to the
      provisions described under "Limitations on Restricted Payments."

   Limitations on Mergers and Certain Other Transactions.  Kaiser will not:

   .  in a single transaction or a series of related transactions, consolidate
      or merge with or into, or sell, lease, convey or otherwise dispose of all
      or substantially all of its assets, or assign any of its obligations under
      the new notes or the indenture, to any Person, or

   .  adopt a Plan of Liquidation unless, in either case:

     .  the Person formed by or surviving the consolidation or merger, if other
        than Kaiser, or to which the sale, lease, conveyance or other
        disposition or assignment is made, or, in the case of a Plan of
        Liquidation, the Person to which assets are transferred, each of which
        is referred to as a "Successor," is a domestic corporation and the
        Successor assumes by supplemental indenture in a

                                       64
<PAGE>


        form satisfactory to the Trustee all of the obligations of Kaiser under
        the new notes and the indenture;

     .  immediately prior to and immediately after and giving effect to the
        transaction and the assumption of the obligations as set forth in the
        preceding clause above and the incurrence of any Indebtedness, no
        Default or Event of Default will have occurred and be continuing; and

     .  immediately after and giving effect to the transaction and the
        assumption of the obligations as set forth in the first clause above and
        the incurrence of any Indebtedness, and the use of its net proceeds on a
        pro forma basis:

        .  the Consolidated Tangible Net Worth of Kaiser or the Successor would
           be at least equal to the Consolidated Tangible Net Worth of Kaiser
           immediately prior to the transaction and

        .  Kaiser or the Successor could incur at least $1.00 of additional
           Senior Indebtedness under the covenant described under "Limitations
           on Additional Indebtedness."

     In addition, Kaiser will not permit any Single Purpose Subsidiary that has
outstanding Indebtedness to consolidate or merge with any other Person other
than a Person whose activities are limited to ownership of a portion of the same
project in which the merging Single Purpose Subsidiary owns an interest.

     The foregoing provisions of the indenture will not prohibit a transaction
whose sole purpose, as determined in good faith by the Board of Directors and
evidenced by a Board Resolution, is to change the state of incorporation of
Kaiser or a Single Purpose Subsidiary and the transaction does not have as one
of its purposes the evasion of the limitations described above.

     Limitations on Guarantees.  Kaiser will not permit any of its Restricted
Subsidiaries to guarantee any Indebtedness, other than guarantees of
indebtedness under the Bank Credit Agreement permitted under the provisions of
the covenant described under "Limitations on Subsidiary Debt and Preferred
Stock" by subsidiaries of Kaiser who have delivered similar guarantees prior to
the date of the indenture, unless Kaiser causes each Subsidiary to execute and
deliver to the Trustee a supplemental indenture, pursuant to which the
Subsidiary unconditionally guarantees the payment of principal and interest on
the new notes.  Any guarantee will be subordinated in right of payment to the
guarantee by the Subsidiary pursuant to the Bank Credit Agreement.

Events of Default

     An "Event of Default" is defined in the indenture to include any of the
following:

     .  failure by Kaiser to pay interest on any of the new notes when it
        becomes due and payable and the continuance of any failure for 30 days;

     .  failure by Kaiser to pay the principal of the new notes when it becomes
        due and payable, whether at stated maturity, upon redemption, upon
        acceleration or otherwise, including failure to make payment pursuant to
        an Asset Sale Offer;

     .  failure by Kaiser to comply with any covenant in the indenture and
        continuance of the failure for 60 days after notice of the failure has
        been given to Kaiser by the Trustee or by the holders of at least 25% of
        the aggregate principal amount of the new notes then outstanding;

     .  failure by Kaiser or any of its subsidiaries to make any payment when
        due or during any applicable grace period, and the continuation of the
        failure for seven days, with respect to any indebtedness of Kaiser or
        any of its subsidiaries, other than Non-Recourse Indebtedness of a
        Single Purpose Subsidiary, that has an aggregate outstanding principal
        amount of $2 million or more;

                                       65
<PAGE>


    .  a default under any indebtedness, other than Non-Recourse Indebtedness of
       a Single Purpose Subsidiary, if:

       .  the default results in the holder or holders of the indebtedness
          causing the indebtedness to become due prior to its stated maturity
          and

       .  the principal amount of the indebtedness, together with the principal
          amount of any other indebtedness, which maturity has been accelerated,
          aggregates $2 million or more at any one time outstanding;

    .  a court or courts of competent jurisdiction have entered one or more
       final judgments or orders against Kaiser or any of its subsidiaries for
       payment of amounts which exceed $2 million in the aggregate and the
       judgment or judgments have not been satisfied, stayed, annulled or
       rescinded within 60 days of being entered; and

    .  some events of bankruptcy, insolvency or reorganization involving Kaiser
       or any of its subsidiaries.

    If an Event of Default, other than an Event of Default resulting from
bankruptcy, insolvency or reorganization involving Kaiser, has occurred and is
continuing under the indenture, the Trustee by written notice to Kaiser, or the
holders of at least 25% in aggregate principal amount of the new notes then
outstanding by written notice to Kaiser and the Trustee, may declare all amounts
owing under the new notes to be due and payable immediately.  Upon declaration
of acceleration, the aggregate principal and interest on the outstanding notes
will immediately become due and payable.  If an Event of Default results from
bankruptcy, insolvency or reorganization involving Kaiser, all outstanding notes
will become due and payable without any further action or notice.  In some
cases, the holders of a majority in aggregate principal amount of the new notes
then outstanding may waive an existing Default or Event of Default and its
consequences, except a default in the payment of principal and interest on the
new notes.

    The holders of new notes may not directly enforce the provisions of the
indenture or the new notes except as provided in the indenture.  Subject to some
limitations, holders of a majority in principal amount of the new notes then
outstanding may direct the Trustee in its exercise of any trust or power, as
long as the direction does not conflict with the terms of the indenture.  The
Trustee may withhold from the holders of new notes notice of any continuing
Default or Event of Default, except any Default or Event of Default in payment
of principal and interest on the new notes, if the Trustee determines that
withholding the notice is in the holders' interest.

    Kaiser is required to deliver to the Trustee annually a statement regarding
compliance with the indenture and, upon any Officer of Kaiser becoming aware of
any Default or Event of Default, a statement specifying the Default or Event of
Default and what action Kaiser is taking or proposes to take with respect to the
Default or Event of Default.

Discharge of Indenture

    The indenture will permit Kaiser to terminate all of its obligations under
the indenture, other than the obligation to pay the principal and interest on
the new notes, and some other obligations at any time by taking the following
actions:

    .  depositing in trust with the Trustee, under an irrevocable trust
       agreement, money or U.S. government obligations in an amount sufficient
       to pay principal and interest on the new notes to their maturity or
       redemption and

    .  complying with some other conditions, including delivery to the Trustee
       of an opinion of counsel or a ruling received from the Internal Revenue
       Service to the effect that holders of new notes will not recognize
       income, gain or loss for federal income tax purposes as a result of
       Kaiser's exercise of the

                                       66
<PAGE>


       right and will be subject to federal income tax on the same amount and in
       the same manner and at the same times as would have been the case
       otherwise.

Transfer and Exchange

    A holder of new notes will be able to register the transfer of or exchange
of his new notes only in accordance with the provisions of the indenture.  The
Trustee may require a holder, among other things, to furnish appropriate
endorsements and transfer documents, and to pay any taxes and fees required by
law or permitted by the indenture.  Without the prior consent of Kaiser, the
Trustee is not required:

    .  to register the transfer or exchange of any new note selected for
       redemption;

    .  to register the transfer or exchange of any new note for a period of 15
       days before a selection of new notes to be redeemed; or

    .  to register the transfer or exchange of a new note between a record date
       and the next succeeding interest payment date.

The holder of a new note will be treated as the owner of a new note for all
purposes.

Amendment, Supplement and Waiver

    Subject to some exceptions, the indenture or the new notes may be amended
or supplemented with the consent, which may include consents obtained in
connection with a tender offer or exchange offer for notes, of the holders of at
least a majority in principal amount of the new notes then outstanding, and any
existing Default under, or compliance with any provision of, the indenture may
be waived, other than any continuing Default or Event of Default in the payment
of the principal or interest on the new notes or that resulted from the failure
to comply with the covenant described under "Change of Control," with the
consent, which may include consents obtained in connection with a tender offer
or exchange offer for notes, of the holders of a majority in principal amount of
the new notes then outstanding.  Without the consent of any holder, Kaiser and
the Trustee may amend or supplement the indenture or the new notes to cure any
ambiguity, defect or inconsistency, to provide for uncertificated new notes in
addition to or in place of certificated new notes, to provide for the assumption
of Kaiser's obligations to holders in the case of a merger or acquisition, or to
make any change that does not adversely affect the rights of any holder.

    Kaiser may not, without the consent of each affected holder of new notes:

    .  extend the maturity of any new note;

    .  affect the terms of any scheduled payment of interest on or principal of
       the new notes, including without limitation any redemption provisions;

    .  reduce the percentage of holders necessary to consent to an amendment,
       supplement or waiver to the indenture.

    The right of any holder of new notes to participate in any consent required
or sought pursuant to any provision of the indenture, and the obligation of
Kaiser to obtain this consent otherwise required from the holder, may be subject
to the requirement that the holder be the holder of record of any new notes with
respect to which the consent is required or sought as of a date identified by
the Trustee in a notice furnished to holders in accordance with the terms of the
indenture.

                                       67
<PAGE>


Concerning the Trustee

     The indenture contains some limitations on the rights of the Trustee,
should it become a creditor of Kaiser, to obtain payment of claims in some
cases, or to realize on some property received in respect of any claim as
security or otherwise.  The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest, as defined in
the indenture, it must eliminate this conflict or resign.

     The holders of a majority in principal amount of the then outstanding new
notes will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to some
exceptions.  The indenture provides that, in case an Event of Default occurs and
is not cured, the Trustee will be required, in the exercise of its power, to use
the degree of care of a prudent person in similar circumstances in the conduct
of his own affairs.  Subject to these provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the indenture at the
request of any holder of new notes, unless the holder has offered to the Trustee
security and indemnity satisfactory to the Trustee.

<PAGE>

        except that if any calculation of Kaiser's Consolidated Fixed Charge
        Coverage Ratio requires the use of any quarter beginning prior to

        quarter and, instead, shall be based on the lesser number of full fiscal
        quarters completed after January 1, 2000; and except that if any
        calculation requires the use of any quarter prior to the date that any
        Asset Sale was consummated, or that any Indebtedness was incurred, or
        that any acquisition was effected, by Kaiser or any of its Restricted
        Subsidiaries, this calculation will be made on a pro forma basis, giving
        effect to each Asset Sale, incurrence of Indebtedness or acquisition, as
        the case may be, and the use of any proceeds, as if the same had

Subsidiary of Kaiser, of which 100% of the Common Equity, except for directors'
qualifying shares or certain minority interests owned by other Persons solely
due to local tax considerations or local law requirements that there be more
than one stockholder, but which interest is not in excess of what is required
for this purpose, is owned directly by Kaiser or through one or more wholly-
owned Restricted Subsidiaries of Kaiser.

Satisfaction and Discharge of Indebtedness

     The indenture is discharged and canceled upon payment of all the principal
and interest on the new notes, redemption of all the new notes or deposit with
the Trustee of funds or obligations issued or guaranteed by the United States
sufficient for this payment or redemption.

The Trustee

     The Trustee is Bank of New York.

     The Trustee performs only those duties as are specifically set forth in the
indenture, except during the continuance of an Event of Default.  During the
existence of an Event of Default, the Trustee exercises those rights and powers
vested in it under the indenture and uses the same degree of care and skill in
its exercise as a prudent person would exercise under the circumstances in the
conduct of the person's own affairs.  The holders of a majority in outstanding
amount of the new notes will have the right, during the continuance of an Event
of Default, to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee.  Subject to these
provisions, the Trustee is under no obligation to exercise any of its rights or
powers under the indenture at the request of any of the holders of new notes,
unless they offer to the Trustee security or indemnity satisfactory to it.

     The indenture and provisions of the Trust Indenture Act of 1939
incorporated by reference into the indenture contain limitations on the rights
of the Trustee, should it become a creditor of Kaiser, to obtain payment of
claims in some cases, or to realize on property received in respect of any of
these claims as security or otherwise.  The Trustee is permitted to engage in
other transactions with Kaiser, except that if it acquires any conflicting
interest within the meaning of the Trust Indenture Act of 1939, it must
eliminate this conflict or resign.

Book-Entry, Delivery and Form

     The new notes are initially issued in the form of one global new note.  The
global new note is deposited on the date of the consummation of the exchange
offer with the Trustee as custodian for The Depository Trust Company and
registered in the name of Cede & Co., as nominee of the DTC.

     The DTC is a limited-purpose trust company that was created to hold
securities for its participating organizations and to facilitate the clearance
and settlement of transactions in securities between participants through
electronic book-entry changes in accounts of its participants.  The DTC's
participants include securities brokers and dealers, banks and trust companies,
clearing corporations and some other organizations.  Access to the DTC's system
is also available to other entities such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.  Persons who are not participants
may beneficially own securities held by or on behalf of the DTC only through the
DTC's participants or indirect participants.

   Kaiser expects that pursuant to procedures established by the DTC:

     .  upon deposit of the global new note, the DTC credits the accounts of
        participants exchanging old notes for new notes with portions of the
        principal amount of the global new note and

     .  ownership of the notes evidenced by the global new note is shown on, and
        the transfer of ownership is effected only through, records maintained
        by the DTC, with respect to the interests of the DTC's participants and
        the DTC's indirect participants.

Holders of new notes are advised that the laws of some states require that some
persons take physical delivery in definitive form of securities that they own.
Consequently, the ability to transfer notes evidenced by the global new note
will be limited to this extent.

     So long as the holder of the global new note is the registered owner of any
new notes, the global new note holder is considered the sole holder under the
indenture of any notes evidenced by the global new note.  Beneficial owners of
new notes evidenced by the global new note are considered the owners or holders
under the indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee.  Neither Kaiser nor the
Trustee has any responsibility or liability for any aspect of the records of the
depository or for maintaining, supervising or reviewing any records of the
depository relating to the new notes.

     Payments in respect of the principal and interest, if any, on any new notes
registered in the name of the global new note holder on the applicable record
date is payable by the Trustee to or at the direction of the global new note
holder in its capacity as the registered holder under the indenture.  Under the
terms of the indenture, Kaiser and the Trustee may treat the persons in whose
names new notes, including the global new note, are registered as the owners for
the purpose of receiving these payments.  Consequently, neither Kaiser nor the
Trustee has any responsibility or liability for the payment of these amounts to
beneficial owners of new notes.  Kaiser believes, however, that it is currently
the policy of the DTC to immediately credit the accounts of the relevant
participants with these payments, in amounts proportionate to their respective
holdings of beneficial interests in the relevant security as shown on the
records of the DTC.  Payments by the DTC's participants and the DTC's indirect
participants to the beneficial owners of new notes is governed by standing
instructions and customary practice and is the responsibility of the DTC's
participants or the DTC's indirect participants.

     Certificated Notes.  Any beneficial owner of new notes evidenced by the
global new note may obtain notes in the form of registered certificated new
notes.  If Kaiser notifies the Trustee in writing that the DTC is no longer
willing or able to act as a depository and Kaiser is unable to locate a
qualified successor within 90 days then, upon surrender by the global new note
holder of its global new note, new notes in this form will be issued to each
person that the global new note holder and the DTC identify as being the
beneficial owner of the related new notes.

                                      79
<PAGE>



     Neither Kaiser nor the Trustee is liable for any delay by the global new
note holder or the DTC in identifying the beneficial owners of notes and Kaiser
and the Trustee may conclusively rely on, and is protected in relying on,
instructions from the global new note holder or the DTC for all purposes.

     Same-Day Settlement and Payment.  The indenture requires that payments for
the notes represented by the global new note, including principal, interest and
liquidated damages, if any, be made by wire transfer of immediately available
funds to the accounts specified by the global new note holder.  With respect to
certificated new notes, Kaiser makes all payments of principal and interest by
wire transfer of immediately available funds to the accounts specified by the
holders or, if no account is specified, by mailing a check to each holder's
registered address.  Secondary trading in long-term notes and debentures of
corporate issuers is generally settled in clearing-house or next-day funds.  In
contrast, the notes represented by the global new note are expected to trade in
the DTC's same-day funds settlement system, and any permitted secondary market
trading activity in these notes will, therefore, be required by the DTC to be
settled in immediately available funds.  Kaiser expects that secondary trading
in the certificated new notes will also be settled in immediately available
funds.

                                    PART II


                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  Indemnification of directors and officers.

         Under the Delaware General Corporation Law (the "Delaware Law"), a
corporation may indemnify any person who was or is a party or is threatened to
be made a party to an action by reason of the person's past or present service
as a director, officer, employee, or agent of the corporation or of the person's
past or present service, at the corporation's request, as a director, officer,
employee, or agent of another corporation, partnership, joint venture, trust, or
other enterprise. Under the Delaware Law, a corporation may indemnify such
persons against expenses (including attorneys' fees), judgments, fines, and
amounts paid in settlement that are actually and reasonably incurred by that
person in connection with such action. The Delaware Law provides, however, that
such person must have acted in good faith and in a manner that such person
reasonably believed to be in (or not opposed to) the corporation's best
interests. In respect of any criminal action or proceeding, an indemnifiable
person must have no reasonable cause to believe such conduct to be unlawful. In
addition, the Delaware Law permits no indemnification in any action by or in the
right of the corporation where such person has been adjudged liable to the
corporation, unless, and only to the extent that, a court determines that such
person fairly and reasonably is entitled to indemnity for such costs the court
deems proper in spite of liability adjudication.

         The sections of the Company's Restated Certificate of Incorporation and
Amended and Restated Bylaws relating to indemnification of directors and
officers provide for mandatory indemnification of directors and officers on
generally the same terms as permitted by the Delaware Law.

ITEM 22.  UNDERTAKINGS

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

         (2) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 23(a) or Section 15(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Exchange Act) that is incorporated by reference in the registration
statement 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) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         (4) The undersigned registrant hereby undertakes to supply by means of
a post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

         (5) The undersigned registrant hereby undertakes:

             (a)  To file, during any period in which offers and 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;

                       (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


                                      II-8
<PAGE>


                  thereof) which, individually or in the aggregate, represent a
                  fundamental change in the information set forth in the
                  registration statement. Notwithstanding the foregoing, any
                  increase or decrease in volume of securities offered (if the
                  total dollar value of securities offered would not exceed that
                  which was registered) and any deviation from the low or high
                  and of the estimated maximum offering range may be reflected
                  in the form of prospectus filed with the Commission pursuant
                  to Rule 424(b) if, in the aggregate, the changes in volume and
                  price represent no more than 20 percent change in the maximum
                  aggregate offering price set forth in "Calculation of
                  Registration Fee" table in the effective registration
                  statement;

                       (iii) To include any material information with respect to
                  the plan of distribution not previously disclosed in the
                  registration statement or any material change to such
                  information in the registration statement;

         provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if
         the registration statement is on Form S-3, Form S-8 or Form F-3, and
         the information required to be included in a post-effective amendment
         by those paragraphs is contained in periodic reports filed with or
         furnished to the Commission by the registrant pursuant to Section 13 of
         15(d) of the Exchange Act that are incorporated by reference in the
         registration statement.

                  (b)  That for the purposes of determining any liability under
         the Securities Act, 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.

                  (c)  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.

dividend rate shall increase to 14% from and after the quarter next following
a Change of Control (as defined in Section 5(c)).

          (b) All dividends paid with respect to shares of the Series 5
Convertible Preferred Stock pursuant to Section 3(a) shall be paid pro rata to

to exceed 100, including all shares held by holders who, after giving effect to
such redemption, would hold less than 100 shares, as may be specified by the
Corporation.

          (iv)  In the event the Corporation shall redeem shares of Series 5
Convertible Preferred Stock, written notice of such redemption shall be given by
first class mail, postage prepaid mailed not less than 30 days nor more than 60
days prior to the redemption date, to each holder of record of the shares to be
redeemed at such holder's address as the same appears on the stock register of
the Corporation; provided, however, that no failure to give such notice nor any
                 --------  -------
defect therein shall affect the validity of the proceeding for the redemption of
any shares of Series 5 Convertible Preferred Stock to be redeemed except as to
the holder to whom the Corporation has failed to give said notice or except as
to the holder whose was defective.  Each such notice shall state:  (i) the
                                                                    -
redemption date; (ii) the number of shares of Series 5 Convertible Preferred
                  --
Stock to be redeemed and, if less than all the shares held by such holder are to
be redeemed from such holder, the number of shares to be redeemed from such
holder or the method by which the number of shares to be redeemed will be
determined; (iii) the redemption price; (iv) the place or places where
             ---                         --
certificates for such shares are to be surrendered for payment of the redemption
price; and (v) that dividends on the shares to be redeemed will cease to accrue
            -
on such redemption date.  The Board of Directors shall be authorized to
establish such other reasonable procedures for redemption and payment of the
redemption price that are not inconsistent with the foregoing provisions.

          (v)   Notice having been mailed as aforesaid, from and after the
redemption date (unless default shall be made by the Corporation in providing
money for the payment of the redemption price of the shares called for
redemption) dividends on the shares of Series 5 Convertible Preferred Stock so
called for redemption shall cease to accrue and said shares shall no longer be
deemed to be outstanding and shall have the status of authorized but unissued
shares of Preferred Stock, undesignated as to series, and all rights of the
holders thereof as stockholders of the Corporation (except the right to receive
from the Corporation the redemption price and any accrued and unpaid dividends)
shall cease.  Upon surrender in accordance with said notice of the certificates
for any shares to redeemed (properly endorsed or assigned for transfer, if the
Board of Directors shall so require and the notice shall so state), such shares
shall be redeemed by the Corporation at the redemption price aforesaid plus any
accrued and unpaid dividends.  In case fewer than all the shares represented by
any such certificate are

                                       6

redeemed, a new certificate shall be issued representing the unredeemed shares
without cost to the holder hereof.

          (c)  Repurchase in Connection with a Change of Control.  (i)  If a
               -------------------------------------------------
Change of Control (as defined below) shall occur, each holder of Series 5
Convertible Preferred Stock shall have the right to require the Corporation to
repurchase all or any part (but not any fractional shares) of that holder's
Series 5 Convertible Preferred Stock pursuant to the offer described below (the
"Change of Control Offer"). In the Change of Control Offer, the Corporation
shall offer a payment in cash equal to 101% of the Liquidation Preference Per
Share repurchased (the "Change of Control Payment"). Within 30 days following
any Change of Control, the Corporation shall mail a notice to each holder of
Series 5 Convertible Preferred Stock describing the transaction or transactions
that constitute the Change of Control and offering to repurchase Series 5
Convertible Preferred Stock on the date specified in such notice, which date
shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed (the "Change of Control Payment Date"), pursuant to the
procedures required by this Certificate of Designation and described in such
notice. The Corporation shall comply with the requirements of federal and state
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Series 5
Convertible Preferred Stock as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with this
Section 5(c), the Corporation shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations under
this Section 5(c) by virtue of such conflict. On the Change of Control Payment
Date, the Corporation shall, to the extent lawful: (x) accept for payment all
                                                    -

Preferred Stock or portions thereof so tendered; and (z) deliver or cause to be
                                                      -
delivered to an agent appointed by the Corporation (the "Transfer Agent") the
Series 5 Convertible Preferred Stock so accepted together with an officers'
certificate stating the Liquidation Preference Per Share or portions thereof
being purchased by the Corporation. The Paying Agent shall promptly mail to each
holder of Series 5 Convertible Preferred Stock so tendered the Change of Control
Payment for such Series 5 Convertible Preferred Stock, and the Transfer Agent
shall promptly authenticate and mail (or cause to be transferred by book-entry)
to each holder of Series 5 Convertible Preferred Stock a new certificate
representing the Series 5 Convertible Preferred Stock equal in Liquidation
Preference Per Share to any unpurchased portion of the Series 5 Convertible
Preferred Stock surrendered, if any. The Corporation shall publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date. The Corporation shall not be required to make a
Change of Control Offer upon a Change of Control if a third party makes the
Change of Control Offer in the manner, at the times and otherwise in compliance
with the requirements set forth in this Certificate of Designation applicable to
a Change of Control Offer made by the Corporation and purchases all Series 5
Convertible Preferred Stock validly tendered and not withdrawn under such Change
of Control Offer. Notwithstanding the provisions of this Section 5(c), nothing
in this Section 5(c) shall operate (or be deemed to operate) to prevent the
Corporation from redeeming in accordance with the provisions of Section 5(a) any
shares of Series 5 Convertible
                                       7

directly or indirectly, more than 50% of the aggregate voting power of all
classes of Common Equity of such Person or group immediately after such
transactions shall not be a Change of Control; (w) the acquisition by the
                                                -

          6.   Conversion.
               ----------

          (a)  Upon the terms and in the manner set forth in this Section 6 and
subject to prior redemptions, if any, of Series 5 Convertible Preferred Stock
made in accordance with Section 5, each share of the Series 5 Convertible
Preferred Stock shall be convertible, at the option of the holder thereof at any
time (x) on and after December 31, 2001 and (y) if the Corporation shall fail to
      -                                      -
make a Change of Control Offer in accordance with Section 5(c)(i), in each case,
upon surrender to the Corporation of the certificates for the shares to be
converted, into a number of fully paid and nonassessable shares of Common Stock
equal to Liquidation Preference Per Share divided by the Current Market Price
                                          ----------
(as defined below) (the "Conversion Ratio"); provided, however, that the right
                                             --------  -------
to convert shares of Series 5 Convertible Preferred Stock that have been called
for redemption pursuant to Section 5 shall terminate at the close of business on
the date notice of redemption is first sent or given by the Corporation with
respect to such shares, unless the Corporation shall default in making payment
of the amount payable upon such redemption.

          (b)  In order to convert shares of the Series 5 Convertible Preferred
Stock, the holder thereof shall (i) deliver a properly completed and duly
                                 -
executed written notice of election to convert to the Corporation at its
principal office or at the office of the agency which may be

                                       9
<PAGE>


maintained for such purpose (the "Conversion Agent") specifying in such notice
the number (in whole shares) of shares of the Series 5 Convertible Preferred
Stock to be converted and the name or names in which such holder wishes the
certificate or certificates for shares of Common Stock to be issued, (ii)
                                                                      --
surrender the certificate for such shares of Series 5 Convertible Preferred
Stock to the Corporation or the Conversion Agent, accompanied, if so required by
the Corporation or the Conversion Agent, by a written instrument or instruments
of transfer in form reasonably satisfactory to the Corporation or the Conversion
Agent duly executed by the holder or his attorney duly authorized in writing,
and (iii) pay any transfer or similar tax required by law.
     ---

          (c)  (i)   Conversion shall be deemed to have been effected at the
close of business on the date (the "Conversion Date") on which the Corporation
or the Conversion Agent shall have received the notice of election to convert,
the surrendered certificate, any required payments and all other required
documents. Immediately upon conversion, the rights of the holders of converted
shares of Series 5 Convertible Preferred Stock shall cease and the persons
entitled to receive the shares of Common Stock upon the conversion of such
shares of Series 5 Convertible Preferred Stock shall be treated for all purposes
as having become the beneficial owners of such shares of Common Stock.
Conversion shall be at the Conversion Ratio in effect at such time on such date,
unless the stock transfer books of the Corporation shall be closed on that date,
in which event such person or persons shall be deemed to have become such holder
or holders of record of the Common Stock at the close of business on the next
succeeding day on which such stock transfer books are open, but such conversion
shall be at the Conversion Ratio in effect on the date upon which such shares
shall have been surrendered and such notice and any required payments received
by the Corporation.

               (ii)  As promptly as practicable after the Conversion Date, the
Corporation shall deliver or cause to be delivered at the office or agency of
the Conversion Agent, to or upon the written order of the holder of the
surrendered shares of Series 5 Convertible Preferred Stock, a certificate or
certificates representing the number of fully paid, nonassessable shares of
Common Stock into which such shares of Series 5 Convertible Preferred Stock have
been converted in accordance with the provisions of this Section 6, and any cash
payable in respect of fractional shares as provided in Section 6(d).

               (iii) Upon the surrender of a certificate representing shares of
Series 5 Convertible Preferred Stock that is converted in part, the Corporation
shall issue or cause to be issued for the holder a new certificate representing
shares of Series 5 Convertible Preferred Stock equal in number to the
unconverted portion of the shares of Series 5 Convertible Preferred Stock
represented by the Certificate so surrendered.

          (d)  No fractional shares or scrip representing fractional shares of
Common Stock shall be issued upon the conversion of any shares of Series 5
Convertible Preferred Stock.  Instead of any fractional interest in a share of
Common Stock which would otherwise be deliverable upon the conversion of a share
of Series 5 Convertible Preferred Stock, the Corporation shall pay to the holder
of such share (a "Fractional Shareholder") an amount in cash (computed to the
nearest cent) equal to the Current Market Price (as defined below) thereof on
the business day next preceding the day of conversion multiplied by such
                                                      -------------
fractional interest.  If more than one share shall be surrendered for conversion
at the time by the same holder, the

                                       10
<PAGE>


number of full shares of Common Stock issuable upon conversion thereof shall be
computed on the basis of the aggregate stated value of the shares of Series 5
Convertible Preferred Stock so surrendered.

          (e)  Subject to the final sentence of this Section 6(e), for purposes
of any computation under Sections 6(a) and 6(d)(i), the "Current Market Price"
at any date shall be deemed to be the average daily closing price of Common
Stock for the 20 consecutive trading days ending on the trading day prior to the
date in question.  The closing price for each day shall be (x) if the Common
                                                            -
Stock is listed or admitted to trading on a national securities exchange, the
closing price on the New York Stock Exchange Consolidated Tape (or any successor
composite tape reporting transactions on national securities exchanges) or, if
such a composite tape shall not be in use or shall not report transactions in
the Common Stock, the last reported sales price regular way on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading (which shall be the national securities exchange on which the greatest
number of shares of Common Stock has been traded during such 20 consecutive
trading days), or, if there is no transaction on any such day in any such
situation, the mean of the bid and asked prices on such day, or (y) if the
                                                                 -
Common Stock is not listed or admitted to trading on any such exchange, the
closing price, if reported, or, if the closing price is not reported, the
average of the closing bid and asked prices as reported by the National
Association of Securities Dealers Automated Quotation System (NASDAQ) or a
similar source selected from time to time by the Corporation for the purpose.
In the event such closing prices are unavailable, the Current Market Price shall
be deemed to be the fair market value as determined in good faith by the Board
of Directors, on the basis of such relevant factors as it in good faith
considers, in the reasonable judgment of the Board of Directors, appropriate.
All calculations under this Section 6(e) shall be made to the nearest one-
hundredth of a cent or to the nearest one-hundredth of a share, as the case may
be.  At any time after a Change of Control or December 31, 2004, the Current
Market Price shall be conclusively deemed to be $.01 per share.

          (f)  The Conversion Ratio shall be subject to adjustment as follows:

               (i)  If, during the 20 consecutive trading day period during
which the determination of the Conversion Ratio occurs, the Corporation shall
(v) declare or pay a dividend on its outstanding Common Stock in shares of
 -
Common Stock or make a distribution to all holders of its Common Stock in shares
of Common Stock, (w) subdivide its outstanding shares of Common Stock into a
                  -
greater number of shares of Common Stock, (x) combine its outstanding shares of
                                           -
Common Stock into a smaller number of shares of Common Stock, (y) issue by
                                                               -
reclassification of its shares of Common Stock other securities of the
Corporation or (z) issue or sell shares of Common Stock (or securities
                -
convertible into or exchangeable for Common Stock) without consideration or for
a consideration per share of Common Stock the fair market value of which as of
the date of such issuance or sale is less than the Current Market Price as of
such date, then the Conversion Ratio in effect immediately prior thereto shall
be adjusted appropriately by the Board of Directors so that the holder of any
shares of Series 5 Convertible Preferred Stock thereafter converted shall be
entitled to receive the number and kind of shares of Common Stock of other
securities that the holder would have owned or have been entitled to receive
after the happening of any of the events described above had such shares of
Series 5 Convertible Preferred Stock been converted immediately prior to the
happening of such

                                       11
<PAGE>


event or any record date with respect thereto. An adjustment made pursuant to
this Section 6(f)(i) shall be applied by the Board of Directors in its
reasonable judgment, and shall become effective on the date of the dividend
payment, subdivision, combination, issuance or sale retroactive to the record
date with respect thereto, if any, for such event. Such adjustment shall be made
successively.

               (ii)  Notwithstanding the foregoing, no adjustments of any kind
under this Section 6(f)(ii) shall be made with respect to the sale and issuance
by the Corporation of any shares of Common Stock, rights, options, warrants or
convertible or exchangeable securities containing the right to subscribe for or
purchase shares of Common Stock in connection with either (x) an underwritten
                                                           -
public offering or (y) any transaction as to which the Corporation has received
                    -
a written opinion of a nationally recognized investment bank stating that the
transaction is fair to the Corporation from a financial point of view.

               (iii) No adjustment in the Conversion Ratio shall be required
unless such adjustment would require an increase or decrease of at least 1% of
such price; provided, however, that any adjustments which by reason of this
            --------  -------
Section 6(f)(iii) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.  All calculations under this Section
6(f) shall be made to the nearest one-hundredth of a cent or to the nearest one-
hundredth of a share, as the case may be.

          7.   Voting Rights.
               -------------

          (a)  Generally.  The holders of record of shares of Series 5

time to time be increased or decreased by adjustments made on the records of the
Warrant Agent, as custodian for the Depositary, as provided in this Agreement.

          Pending the preparation of definitive Warrant Certificates, temporary
Warrant Certificates may be issued, which may be printed, lithographed,
typewritten, mimeographed or otherwise produced, and which will be substantially
of the tenor of the definitive Warrant Certificates in lieu of which they are
issued.

          If temporary Warrant Certificates are issued, the Company will cause
definitive Warrant Certificates to be prepared without unreasonable delay.
After the preparation of definitive Warrant Certificates, the temporary Warrant
Certificates shall be exchangeable for definitive Warrant Certificates upon
surrender of the temporary Warrant Certificates to the Warrant Agent, without
charge to the Holder.  Until so exchanged the temporary Warrant Certificates
shall in all respects be entitled to the same benefits under this Agreement as
definitive Warrant Certificates.

Section 2.02  Execution and Delivery of Warrant Certificates

          Warrant Certificates evidencing Warrants to purchase initially an
aggregate of up to 882,000 shares of Common Stock shall be executed, on or after
the date of this Agreement, by the Company and delivered to the Warrant Agent
for countersignature, and the Warrant Agent shall countersign and deliver such
Warrant Certificates upon the order and at the direction of the Company to such
holders of Old Notes as so ordered and directed.  The Warrant Agent is hereby
authorized to countersign and deliver Warrant Certificates as required by this
Section 2.02 or by Section 3.04, Article V or Section 9.04.  The Warrant
Certificates shall be executed on behalf of the Company by its Chairman, Chief
Executive Officer or President or by any of its Vice Presidents, either manually
or by facsimile signature.  The Warrant Certificates shall be authenticated by
manual signature of an authorized signatory of the Warrant Agent and shall not
be valid for any purpose unless so countersigned, and shall be dated the date of
authentication by the Warrant Agent.  In case any officer of the Company whose
signature shall have been placed upon any of the Warrant Certificates shall
cease to be the Chairman, Chief Executive Officer, President or a Vice President
of the Company before countersignature by the Warrant Agent and


                                       4

issuance and delivery of the Warrant Certificates, such Warrant Certificates
may, nevertheless, be countersigned by the Warrant Agent and issued and
delivered with the same force and effect as though such person had not ceased to
be such officer of the Company.


                                  ARTICLE III

               NUMBER OF UNDERLYING SHARES; EXERCISE OF WARRANTS;
                     EXPIRATION; NON-SURVIVING COMBINATION

Section 3.01  Number of Underlying Shares

          Each Warrant Certificate shall, when countersigned by the Warrant
Agent, entitle the Holder of the Warrant Certificate, subject to the provisions
of the Warrant Certificate, and of this Agreement, to receive one share of
Common Stock for each Warrant represented by the Warrant Certificate, subject to
adjustment as provided in this Agreement, upon payment of the Purchase Price for
each of such shares.

Section 3.02  Exercise of Warrants

          Subject to the terms and conditions set forth in this Agreement, the
Warrants shall be exercisable at any time after their issuance and on or prior
to the Expiration Date.

Section 3.03  Expiration of Warrants

          The Warrants shall terminate and become void as of the close of
business on the Expiration Date; provided that the Warrants will terminate and
become void prior to the Expiration Date in the event of a Non-Surviving
Combination, pursuant to Section 3.05.

          The Company shall give notice not less than 90, and not more than 120,
days prior to the Expiration Date to the Holders of all then-outstanding
Warrants to the effect that the Warrants will terminate and become void as of
the close of business on the Expiration Date; provided that the failure by the
Company to give such notice as provided in this Section shall not affect such
termination and status of the Warrants as of the close of business on the
Expiration Date.

Section 3.04  Method of Exercise

          In order to exercise a Warrant, the Holder must surrender the Warrant
Certificates evidencing such Warrant to the Warrant Agent, with one of the forms
on the reverse of or attached to the Warrant Certificate duly executed, and
tender the Purchase Price.  The Purchase Price shall be payable by certified or
official bank check or wire transfer, payable in United States currency to the
order of the Company.

          If fewer than all of the Warrants represented by a Warrant Certificate
are being exercised, such Warrant Certificate shall be surrendered and, subject
to the provisions of


                                       5
<PAGE>


Article V, a new Warrant Certificate of the same tenor and for the number of
Warrants that were not exercised shall be executed by the Company. The Warrant
Agent shall countersign the new Warrant Certificate, register it in such name or
names as may be directed in writing by the Holder and deliver the new Warrant
Certificate to the Person or Persons entitled to receive the same.

          Upon surrender of a Warrant Certificate and payment of the Purchase
Price in conformity with the foregoing provisions, the Warrant Agent shall
promptly notify the Company and deliver or cause to be delivered to the
exercising Holder appropriate evidence of ownership of any shares of Common
Stock or other securities or property (including any money) to which the Holder
is entitled, subject to the provisions of Section 9.02.

Section 3.05  Non-Surviving Combination

          (a) If the Company proposes, prior to the Expiration Date, to enter
into a transaction that would constitute a Non-Surviving Combination if
consummated, the Company shall give written notice to the Warrant Agent and to
the Holders of Warrants, promptly after an agreement in principle is reached
with respect to the Non-Surviving Combination but in no event less than 30 days
prior to the consummation of the Non-Surviving Combination.  Such notice shall
describe the transaction in reasonable detail and specify the consideration to
be received by the Holders.  The Company shall also furnish to each Holder of
Warrants all notices and materials furnished to its stockholders in connection
with such transactions.

          (b) The Company agrees that it will not enter into an agreement
providing for a Non-Surviving Combination, unless the party to such transaction
that is the surviving entity (the "Survivor") shall be obligated to distribute
or pay to each Holder of Warrants, upon payment of the Purchase Price prior to
the Expiration Date, the number of shares of stock or other securities or other
property (including any cash) of the Survivor that would have been distributable
or payable on account of the Common Stock issuable if such Holder's Warrants had
been exercised immediately prior to such Non-Surviving Combination (or, if
applicable, the record date for such transaction).  Following the consummation
of a Non-Surviving Combination, the Warrants shall represent only the right to
receive such shares of stock or other property from the Survivor upon payment of
the Purchase Price prior to the Expiration Date.

Section 3.06  Use of Series 5 Convertible Preferred Stock for Exercise of
Warrants

          Any Holder who is also a holder of the Company's Series 5 Redeemable
Cumulative Convertible Preferred Stock ("Series 5 Convertible Preferred Stock")
issued on the date of initial issuance of such Series 5 Convertible Preferred
Stock, may, at such Holder's option, use shares of Series 5 Convertible
Preferred Stock held by such Holder in lieu of cash to pay the exercise price to
acquire shares of Common Stock pursuant to the Warrants.  For purposes of this
Section 3.06, each share of Series 5 Convertible Preferred Stock shall have a
value equal to the Liquidation Preference Per Share (as such term is defined in
the Company's Certificate of Designation relating to the Series 5 Convertible
Preferred Stock.)

                                  ARTICLE IV

                                  ADJUSTMENTS

Section 4.01  Adjustments of Exercise Price and Number of Shares of Common Stock

          The number and kind of shares purchasable upon the exercise of
Warrants and the Purchase Price shall be subject to adjustment from time to time
as follows:

          (a) Changes in Common Stock.  In the event the Company shall, at any
              -----------------------
time or from time to time, (i) issue any shares of Common Stock as a stock
                            -
dividend to the holders of Common Stock, (ii) subdivide or combine the
                                          --
outstanding shares of Common Stock into a greater or lesser number of shares,
(iii) issue any shares of its capital stock in a reclassification or
 ---
reorganization of the Common Stock, or (iv) issue any shares of Common Stock
                                        --
pursuant to the terms of the agreement by which the Company acquired ICT
Spectrum Constructors, Inc. (any such issuance, subdivision, combination,
reclassification or reorganization being called a "Change of Shares"), then (x)
                                                                             -
in the case of (i) or (ii) above, the number of shares of Common Stock that may
be purchased upon the exercise of each Warrant shall be adjusted to the number
of shares of Common Stock that the Holder of such Warrant would have owned or
have been entitled to receive after the happening of such event had such Warrant
been exercised immediately prior to the record date (or, if there is no record
date, the effective date) for such event, and the Purchase Price shall be
adjusted to the price (calculated to the nearest 1,000th of one cent) determined
by multiplying the Purchase Price immediately prior to such event by a fraction,
the numerator of which shall be the number of shares of Common Stock purchasable
with one Warrant immediately prior to such event and the denominator of which
shall be the number of shares of Common Stock purchasable with one Warrant after
the adjustment referred to above and (y), in the case of (iii) above, paragraph
                                      -
(l) below shall apply.  An adjustment made pursuant to clause (x) of this
paragraph (a) shall become effective retroactively immediately after the record
date in the case of such dividend and shall become effective immediately after
the effective date in other cases, but any shares of Common Stock issuable
solely as a result of such adjustment shall not be issued prior to the effective
date of such event.

          (b) Common Stock Distribution.  In the event the Company shall, at any
              -------------------------
time or from time to time, issue, sell or otherwise distribute (including by way
of deemed distributions pursuant to paragraphs (c) and (d) below) any shares of
Common Stock (other than pursuant to a Change of Shares or the exercise of any
Option, Convertible Security (each as defined in paragraph (c) below) or
Warrant) (any such event, including any deemed distributions described in
paragraphs (c) and (d), being called a "Common Stock Distribution"), for a
consideration per share less than the current market price per share of Common
Stock (as defined in paragraph (f) below), on the date of such Common Stock
Distribution, then, effective upon such Common Stock Distribution, the Purchase
Price shall be reduced to the price (calculated to the nearest 1,000th of one
cent) determined by multiplying the Purchase Price in effect immediately prior
to such Common Stock Distribution by a fraction, the numerator of which shall be
the sum of (i) the number of shares of Common Stock outstanding (exclusive of
            -
any treasury shares) immediately prior to such Common Stock Distribution
multiplied by the current market price per share of Common Stock on the date of
such Common Stock Distribution, plus (ii) the
                                ----  --


                                       7
<PAGE>


consideration, if any, received by the Company upon such Common Stock
Distribution, and the denominator of which shall be the product of (x) the total
                                                                    -
number of shares of Common Stock outstanding (exclusive of any treasury shares)
immediately after such Common Stock Distribution and (y) the current market
                                                      -
price per share of Common Stock on the date of such Common Stock Distribution.

          If any Common Stock Distribution shall require an adjustment to the
Purchase Price pursuant to the foregoing provisions of this paragraph (b),
including by operation of paragraph (c) or (d) below, then, effective at the
time such adjustment is made, the number of shares of Common Stock purchasable
upon the exercise of each Warrant shall be increased to a number determined by
multiplying the number of such shares so purchasable immediately prior to such
Common Stock Distribution by a fraction, the numerator of which shall be the
Purchase Price in effect immediately prior to such adjustment and the
denominator of which shall be the Purchase Price in effect immediately after
such adjustment.  In computing adjustments under this paragraph, fractional
interests in Common Stock shall be taken into account to the nearest 1,000th of
a share.

          The provisions of this paragraph (b), including by operation of
paragraph (c) or (d) below, shall not operate to increase the Purchase Price or
reduce the number of shares of Common Stock purchasable upon the exercise of any
Warrant, except by operation of paragraph (j) or (k) below.

          (c) Issuance of Options.  In the event the Company shall, at any time
              -------------------
or from time to time, issue, sell, distribute or otherwise grant in any manner
(including by assumption) any rights to subscribe for or to purchase, or any
warrants or options for the purchase of, Common Stock or any stock or securities
convertible into or exchangeable for Common Stock, other than the convertible
preferred stock issuable in the recapitalization concurrently with the issuance
of the Warrants as contemplated in the Registration Statement (any such rights,
warrants or options being called "Options" (the term "Options" shall also
include without limitation any rights ("Rights") to purchase Common Stock and
each other security for which such rights are at any time exercisable issued
pursuant to the Rights Agreement between the Company and the Rights Agent
designated in that Rights Agreement approved by the Board of Directors of the
Company on January 13, 1992, as amended from time to time) and any such
convertible or exchangeable stock or securities being called "Convertible
Securities"), whether or not such Options or the rights to convert or exchange
such Convertible Securities are immediately exercisable, and the price per share
at which Common Stock is issuable upon the exercise of such Options or upon the
conversion or exchange of such Convertible Securities (determined by dividing
(i) the aggregate amount, if any, received or receivable by the Company as
 -
consideration for the issuance, sale, distribution or granting of such Options,
plus the minimum aggregate amount of additional consideration, if any, payable
to the Company upon the exercise of all such Options, plus, in the case of
Options to acquire Convertible Securities, the minimum aggregate amount of
additional consideration, if any, payable upon the conversion or exchange of all
such Convertible Securities, by (ii) the total maximum number of shares of
                                 --
Common Stock issuable upon the exercise of all such Options or upon the
conversion or exchange of all Convertible Securities issuable upon the exercise
of all such Options) is less than the current market price per share of Common
Stock on the date of the issuance, sale,


                                       8
<PAGE>


distribution or granting of such Options then, for purposes of paragraph (b)
above, the total maximum number of shares of Common Stock issuable upon the
exercise of all such Options or upon the conversion or exchange of the total
maximum amount of the Convertible Securities issuable upon the exercise of all
such Options shall be deemed to have been issued as of the date of the issuance,
sale, distribution or granting of such Options and shall be deemed to be
outstanding and the Company shall be deemed to have received as consideration
such price per share, determined as provided above. Except as otherwise provided
in paragraphs (j) and (k) below, no additional adjustment of the Purchase Price
shall be made upon the actual exercise of such Options or upon conversion or
exchange of the Convertible Securities issuable upon the exercise of such
options. If the minimum and maximum numbers or amounts referred to in this
paragraph (c) or in paragraph (d) below cannot be calculated with certainty as
of the date of the required adjustment, such numbers and amounts shall be
determined in good faith by the Board of Directors of the Company.

          (d) Issuance of Convertible Securities.  In the event the Company
              ----------------------------------
shall, at any time or from time to time, issue, sell or otherwise distribute
(including by assumption) any Convertible Securities (other than upon the
exercise of any Option), whether or not the rights to convert or exchange such
Convertible Securities are immediately exercisable, and the price per share at
which Common Stock is issuable upon the conversion or exchange of such
Convertible Securities (determined by dividing (i) the aggregate amount, if any,
                                                -
received or receivable by the Company as consideration for the issuance, sale or
distribution of such Convertible Securities, plus the minimum aggregate amount
of additional consideration, if any, payable to the Company upon the conversion
or exchange of all such Convertible Securities, by (ii) the total maximum number
                                                    --
of shares of Common Stock issuable upon the conversion or exchange of all such
Convertible Securities) is less than the current market price per share of
Common Stock on the date of such issuance, sale or distribution, then, for the
purposes of paragraph (b) above, the total number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities
shall be deemed to have been issued as of the date of the issuance, sale or
distribution of such Convertible Securities and shall be deemed to be
outstanding and the Company shall be deemed to have received as consideration
such price per share, determined as provided above.  Except as otherwise
provided in paragraphs (j) and (k) below, no additional adjustment of the
Purchase Price shall be made upon the actual conversion or exchange of such
Convertible Securities.

          (e) Dividends and Distributions.  In the event the Company shall, at
              ---------------------------
any time or from time to time, distribute to the holders of Common Stock any
dividend or other distribution of cash, evidences of its indebtedness, other
securities or other properties or assets (in each case other than (i) dividends
                                                                   -
payable in Common Stock, Options or Convertible Securities and (ii) any cash
                                                                --
dividend that, when added to all other cash dividends paid in the one year prior
to the declaration date of such dividend (excluding any such other dividend
included in a previous adjustment of the Purchase Price pursuant to this
paragraph (e)), does not exceed 10% of the current market price per share of
Common Stock on such declaration date), or any options, warrants or other rights
to subscribe for or purchase any of the foregoing, then (x) the Purchase Price
                                                         -
shall be decreased to a price determined by multiplying the Purchase Price then
in effect by a fraction, the numerator of which shall be the current market
price per share of Common Stock on the record date for such distribution less
the sum of (I) the cash portion, if
            -


                                       9
<PAGE>


any, of such distribution per share of Common Stock outstanding (exclusive of
any treasury shares) on the record date for such distribution plus (II) the then
                                                              ----  --
fair market value (as determined in good faith by the Board of Directors of the
Company) per share of Common Stock outstanding (exclusive of any treasury
shares) on the record date for such distribution of that portion, if any, of
such distribution consisting of evidences of indebtedness, other securities,
properties, assets, options, warrants or subscription or purchase rights, and
the denominator of which shall be such current market price per share of Common
Stock and (y) the number of shares of Common Stock purchasable upon the exercise
           -
of each Warrant shall be increased to a number determined by multiplying the
number of shares of Common Stock so purchasable immediately prior to the record
date for such distribution by a fraction, the numerator of which shall be the
Purchase Price in effect immediately prior to the adjustment required by clause
(A) of this sentence and the denominator of which shall be the Purchase Price in
effect immediately after such adjustment. The adjustments required by this
paragraph (e) shall be made whenever any such distribution is made and shall be
retroactive to the record date for the determination of stockholders entitled to
receive such distribution.

          (f) Current Market Price.  For the purpose of any computation under
              --------------------
paragraphs (b), (c), (d) and (e) of this Section, the current market price per
share of Common Stock at any date shall be the average of the daily closing
prices for the 20 consecutive trading days ending on the last full trading day
prior to the time and date as of which the current market price is to be
computed in connection with the event giving rise to the adjustment required by
paragraph (b), (c), (d) or (e).  The closing price for any day shall be the last
reported sale price regular way or, in case no such reported sale takes place on
such day, the average of the closing bid and asked prices regular way for such
day, in each case (1) on the principal national securities exchange on which the
                   -
shares of Common Stock are listed or to which such shares are admitted to
trading or (2) if the Common Stock is not listed or admitted to trading on a
            -
national securities exchange, in the over-the-counter market as reported by the
Nasdaq Stock Market or any comparable system or (3) if the Common Stock is not
                                                 -
listed on the Nasdaq Stock Market or a comparable system, as furnished by two
members of the NASD selected from time to time in good faith by the Board of
Directors of the Company for that purpose.  In the absence of all of the
foregoing, or if for any other reason the current market price per share cannot
be determined pursuant to the foregoing provisions of this paragraph (f), the
current market price per share shall be the fair market value  as determined in
good faith by the Board of Directors of the Company.

          (g) Certain Distributions.  If the Company shall pay a dividend or
              ---------------------
make any other distribution payable in Options or Convertible Securities, then,
for purposes of paragraph (b) above (by operation of paragraph (c) or (d) above,
as the case may be) such Options or Convertible Securities shall be deemed to
have been issued or sold without consideration except for such amounts of
consideration as shall have been deemed to have been received by the Company
pursuant to paragraphs (c) or (d) above, as appropriate.

          (h) Consideration Received.  If any shares of Common Stock shall be
              ----------------------
issued and sold in an underwritten public offering, the consideration received
by the Company for such shares of Common Stock shall be deemed to include the
underwriting discounts and commissions realized by the underwriters of such
public offering.  If any shares of Common Stock, Options or Convertible
Securities shall be issued, sold or distributed for a consideration


                                       10
<PAGE>


other than cash, the amount of the consideration other than cash received by the
Company in respect shall be deemed to be the then fair market value of such
consideration (as determined in good faith by the Board of Directors of the
Company). If any Options shall be issued in connection with the issuance and
sale of other securities of the Company, together comprising one integral
transaction in which no specific consideration is allocated to such Options by
the parties thereto, such Options shall be deemed to have been issued, sold or
distributed for such amount of consideration as shall be allocated to such
Options in good faith by the Board of Directors of the Company.

          (i) Deferral of Certain Adjustments.  No adjustment to the Purchase
              -------------------------------
Price (including the related adjustment to the number of shares of Common Stock
purchasable upon the exercise of each Warrant) shall be required under this
Agreement (i) unless such adjustment, together with other adjustments carried
           -
forward as provided below, would result in an increase or decrease of at least
one percent of the Purchase Price, provided that any adjustment which by reason
of this clause (i) of this paragraph (i) is not required to be made shall be
carried forward and taken into account in any subsequent adjustment and (ii)
                                                                         --
solely with respect to Options that are Rights, until the time such Options
become exercisable.

          (j) Changes in Options and Convertible Securities.  If the exercise
              ---------------------------------------------
price provided for in any Options referred to in paragraph (c) above, the
additional consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in paragraph (c) or (d) above, or the rate at
which any Convertible Securities referred to in paragraph (c) or (d) above are
convertible into or exchangeable for Common Stock shall change at any time
(other than under or by reason of provisions designed to protect against
dilution upon an event which results in a related adjustment pursuant to this
Article IV), the Purchase Price then in effect and the number of shares of
Common Stock purchasable upon the exercise of each Warrant shall be readjusted
(effective only with respect to any exercise of any Warrant after such
readjustment) to the Purchase Price and number of shares of Common Stock so
purchasable that would then be in effect had the adjustment made upon the
issuance, sale, distribution or granting of such Options or Convertible
Securities been made based upon such changed purchase price, additional
consideration or conversion rate, as the case may be, but only with respect to
such Options and Convertible Securities as then remain outstanding.

          (k) Expiration of Options and Convertible Securities.  If, at any time
              ------------------------------------------------
after any adjustment to the number of shares of Common Stock purchasable upon
the exercise of each Warrant shall have been made pursuant to paragraph (c), (d)
or (j) above or this paragraph (k), any Options or Convertible Securities shall
have expired unexercised or, solely with respect to Options that are Rights, are
redeemed, the number of such shares so purchasable shall, upon such expiration
or such redemption, be readjusted and shall become such as they would have been
had they been originally adjusted (or had the original adjustment not been
required, as the case may be) as if (i) the only shares of Common Stock deemed
to have been issued in connection with such Options or Convertible Securities
were the shares of Common Stock, if any, actually issued or sold upon the
exercise of such Options or Convertible Securities and (ii) such shares of
Common Stock, if any, were issued or sold for the consideration actually
received by the Company upon such exercise plus the aggregate consideration, if
any, actually received by the Company for the issuance, sale, distribution or
granting of all such Options or Convertible


                                       11
<PAGE>


Securities, whether or not exercised; provided that (x) no such readjustment
                                                     -
shall have the effect of decreasing the number of such shares so purchasable by
an amount (calculated by adjusting such decrease to account for all other
adjustments made pursuant to this Article IV following the date of the original
adjustment referred to above) in excess of the amount of the adjustment
initially made in respect of the issuance, sale, distribution or granting of
such Options or Convertible Securities and (y) in the case of the redemption of
                                            -
any Rights, there shall be deemed (for the purposes of paragraph (c) above) to
have been issued as of the date of such redemption for no consideration a number
of shares of Common Stock equal to the aggregate consideration paid to effect
such redemption divided by the current market price of the Common Stock on the
date of such redemption.

          (l) Other Adjustments.  In the event that at any time, as a result of
              -----------------
an adjustment made pursuant to this Article IV, the Holders shall become
entitled to receive any securities of the Company other than shares of Common
Stock, the number of such other securities so receivable upon exercise of the
Warrants and the Purchase Price applicable to such exercise shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the shares of Common Stock
contained in this Article IV.

          (m) Excluded Transactions.  Notwithstanding any provision in this
              ---------------------
Article IV to the contrary, no adjustment shall be made pursuant to this Article
IV in respect of (i) any change in the par value of the Common Stock, (ii) the
                  -                                                    --
granting of any Options or the issuance of any shares of Common Stock, whether
pursuant to a Company stock option plan, employee stock purchase plan,
employment agreement, or otherwise, in any case, which would otherwise trigger
an adjustment under paragraph (b) above, that may be registered on Form S-8 or
any successor form under the Securities Act, to any officers, directors or
employees of, or any consultants or advisors to, the Company, or (iii) the
                                                                  ---
issuance of Common Stock pursuant to any dividend reinvestment plan; provided
that clause (ii) of this paragraph (m) shall not apply to any such grant or
issuance if, after giving effect to the grant or issuance, the aggregate amount
of Common Stock issued in all transactions covered by clause (ii) of this
paragraph (m) (assuming the exercise of all then outstanding Options granted in
such transactions) would exceed 5% of the number of shares of Common Stock then
outstanding (after giving effect to the exercise of the Options so granted and
all then outstanding Options or Convertible Securities).

Section 4.02  Notice of Adjustment

          Whenever the number of shares of Common Stock or other stock or
property issuable upon the exercise of each Warrant is adjusted, as provided in
this Agreement, the Company shall promptly give a written certificate of the
Company to the Warrant Agent of such adjustment or adjustments and shall cause
the Warrant Agent promptly to mail by first-class mail, postage prepaid, to each
Holder notice of such adjustment or adjustments.  In addition, the Company at
its sole expense shall within 120 calendar days following the end of each fiscal
year of the Company during which any Warrants remain outstanding, and promptly
upon the request of any Holder of a Warrant in connection with the exercise of
any of such Holder's Warrants, cause to be delivered to the Warrant Agent a
certificate of a firm of independent public accountants selected by the Board of
Directors of the Company (who may be the regular


                                       12
<PAGE>


accountants employed by the Company) setting forth the number of shares of
Common Stock or other stock or property issuable upon the exercise of each
Warrant after such adjustment, setting forth a brief statement of the facts
requiring such adjustment and setting forth the computation by which such
adjustment was made. The Warrant Agent shall be entitled to rely on such
certificates and shall be under no duty or responsibility with respect to any
such certificate except to exhibit the same from time to time to any Holder
desiring an inspection of the certificate during reasonable business hours. The
Warrant Agent shall not at any time be under any duty or responsibility to any
Holder to determine whether any facts exist that may require any adjustment of
the number of shares of Common Stock or other stock or property issuable on
exercise of the Warrants, or with respect to the nature or extent or any such
adjustment when made, or with respect to the method employed in making such
adjustment or the validity or value (or the kind or amount) of any shares of
Common Stock or other stock or property which may be issuable on exercise of the
Warrants. The Warrant Agent shall not be responsible for any failure of the
Company to make any cash payment or to issue, transfer or deliver any shares of
Common Stock or stock certificates or other common stock or property upon the
exercise of any Warrant.

Section 4.03  Statement of Warrants

          Irrespective of any adjustment in the number or kind of shares
issuable upon the exercise of the Warrants, Warrants previously or subsequently
issued may continue to express the same number and kind of shares as are stated
in the Warrants initially issuable pursuant to this Agreement.

Section 4.04  Fractional Interest

          The Company shall not be required to issue fractional shares of Common
Stock on the exercise of Warrants.  If more than one Warrant shall be presented
for exercise in full at the same time by the same Holder, the number of full
shares of Common Stock which shall be issuable upon such exercise shall be
computed on the basis of the aggregate number of shares of Common Stock
acquirable on exercise of the Warrants so presented.  If any fraction of a share
of Common Stock would, except for the provisions of this Section, be issuable on
the exercise of any Warrant (or specified portion of a Warrant), the Company
shall pay an amount in cash calculated by it to be equal to the then current
market price per share multiplied by such fraction computed to the nearest whole
cent.  The Holders, by their acceptance of the Warrant Certificates, expressly
waive any and all rights to receive any fraction of a share of Common Stock or a
stock certificate representing a fraction of a share of Common Stock.

          The Warrant Certificates shall be issued in registered form only.  The
Company shall cause to be kept at the office of the Warrant Agent a register in
which, subject to such


                                       13
<PAGE>


reasonable regulations as it may prescribe, the Company shall provide for the
registration of Warrant Certificates and of transfers or exchanges of Warrant
Certificates by the Warrant Agent as provided in this Agreement.

          At the option of the Holder, Warrant Certificates may be exchanged at
such office, upon payment of the charges provided in this Agreement.  Whenever
any Warrant Certificates are so surrendered for exchange, the Company shall
execute, and the Warrant Agent shall countersign and deliver, the Warrant
Certificates that the Holder making the exchange is entitled to receive.

          All Warrant Certificates issued upon any registration of transfer or
exchange of Warrant Certificates shall be the valid obligations of the Company,
evidencing the same obligations, and entitled to the same benefits under this
Agreement, as the Warrant Certificates surrendered for such registration of
transfer or exchange.

Section 5.02  Registration of Transfer and Exchange

          (a) Transfer and Exchange of Warrant Certificates.  When Warrant
              ---------------------------------------------
Certificates are presented to the Warrant Agent with a request to register the
transfer of the Warrant Certificates, the Warrant Agent shall register the
transfer as requested if the requirements under this Agreement as set forth in
this Section 5.02 for such transaction are met; provided that the Warrant
Certificates presented or surrendered for registration of transfer or exchange
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Warrant Agent, duly executed by the Holder  or his
attorney duly authorized in writing.

Warrant Certificate, duly endorsed or accompanied by appropriate instruments of
transfer, in form satisfactory to the Warrant Agent, together with written
instructions from the Company directing the Warrant Agent to make, or to direct
the Depositary to make, an endorsement on the Global Warrant to reflect an
increase in the aggregate number of Warrants represented by the Global Warrant,
then the Warrant Agent shall cancel such Warrant Certificate and cause, or
direct the Depositary to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Warrant Agent, the aggregate
number of Warrants represented by the Global Warrant to be increased
accordingly.  If no Global Warrant is then outstanding, the Company shall issue
and the Warrant Agent shall authenticate such a Global Warrant for the
appropriate number of Warrants.

          (c) Transfer and Exchange of Global Warrants.  The transfer and
              ----------------------------------------
exchange of Global Warrants or beneficial interests in Global Warrants shall be
effected through the Depositary in accordance with this Agreement and the
applicable procedures of the Depositary.

              -----------------------------------------------------------
Warrant Certificate.
- -------------------

               (i)  Any Person having a beneficial interest in a Global Warrant
     may upon request exchange such beneficial interest for a Warrant
     Certificate.  Upon receipt by the Warrant Agent of instructions from the
     Depositary or its nominee on behalf of any Person having a beneficial
     interest in a Global Warrant and upon receipt by the Warrant Agent of a
     written order or such other form of instructions as is customary for the
     Depositary or the Person designated by the Depositary as having such a
     beneficial interest containing registration instructions, then the Warrant
     Agent will cause, in accordance with the standing instructions and
     procedures existing between the Depositary and the Warrant Agent, the
     aggregate number of Warrants represented by the Global Warrant to be
     reduced and, following such reduction, the Company will execute and the
     Warrant Agent will authenticate and deliver to the transferee a Warrant
     Certificate.

               (ii) Warrants issued in exchange for a beneficial interest in a
     Global Warrant pursuant to this Section 5.02(d) shall be registered in such
     names and in such denominations as the Depositary, pursuant to instructions
     from its direct or indirect participants or otherwise, shall instruct the
     Warrant Agent in writing.  The Warrant Agent shall deliver such Warrant
     Certificates to the Persons in whose names such Warrants are so registered.

          (e)  Restrictions on Transfer and Exchange of Global Warrants.
               --------------------------------------------------------
Notwithstanding any other provisions of this Agreement, a Global Warrant may not
be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

          (f)  General.  The Warrant Agent shall retain copies of all letters,
               -------
notices and other written communications received pursuant to this Section 5.02.
The Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Warrant Agent.

          No service charge shall be payable by Holders for any registration of
transfer or exchange of Warrant Certificates.  The Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of Warrant
Certificates.

Section 6.01   No Voting Rights

               Prior to the exercise of the Warrants, no Holder of a Warrant, as
such, shall be entitled to any rights of a stockholder of the Company,
including, without limitation, the right to receive dividends or subscription
rights, the right to vote, to consent, to exercise any preemptive right, to
receive any notice of meetings of stockholders for the election of directors of
the Company or any other matter or to receive any notice of any proceedings of
the Company, except as may be specifically provided for in this Agreement.

Section 6.02   Right of Action

               All rights of action in respect of this Agreement are vested in
the Holders of the Warrants, and any Holder of any Warrant, without the consent
of the Warrant Agent or any Holder of any other Warrant, may, on such Holder's
own behalf and for such Holder's own benefit, enforce, and may institute and
maintain any suit, action or proceeding against the Company suitable to enforce,
or otherwise in respect of, such Holder's rights under this Agreement, including
the right to exercise, exchange or surrender for purchase such Holder's Warrants
in the manner provided in this Agreement.

Section 7.01   Nature of Duties and Responsibilities Assumed

               The Company hereby appoints the Warrant Agent to act as agent of
the Company as set forth in this Agreement. The Warrant Agent hereby accepts the
appointment as agent of the Company and agrees to perform that agency upon the
terms and conditions set forth in this Agreement, by all of which the Company
and the Holders of Warrants, by their acceptance of this Agreement, shall be
bound. The Warrant Agent shall not by countersigning Warrant Certificates or by
any other act under this Agreement be deemed to make any representation as to
validity or authorization of the Warrants or the Warrant Certificates (except as
to its countersignature on the Warrant Certificates) or of any securities or
other property delivered upon exercise of any Warrant, or as to the number or
kind or amount of stock or other securities or other property deliverable upon
exercise of any Warrant or the correctness of the representations of the Company
made in such certificates that the Warrant Agent receives. The Warrant Agent
shall not have any duty to calculate or determine any adjustments with respect
to the kind and amount of shares or other securities or any property receivable
by Holders upon the exercise of Warrants required from time to time, and the
Warrant Agent shall have no duty or responsibility in determining the accuracy
or correctness of any such calculation, other than to apply any adjustment,
notice of which is given by the Company to the Warrant Agent to be


                                       16
<PAGE>


mailed to the Holders in accordance with Section 4.02. The Warrant Agent shall
not (a) be liable for any recital or statement of fact contained in this
     -
Agreement or in the Warrant Certificates or for any action taken, suffered or
omitted by it in good faith in the belief that any Warrant Certificate or any
other document or any signature is genuine or properly authorized, (b) be
                                                                    -
responsible for any failure on the part of the Company to comply with any of its
covenants and obligations contained in this Agreement or in the Warrant
Certificates or (c) be liable for any act or omission in connection with this
                 -
Agreement except for its own gross negligence or willful misconduct. The Warrant
Agent is hereby authorized to accept instructions with respect to the
performance of its duties under this Agreement from the Chief Executive Officer,
the President, any Vice President, the Chief Financial Officer, the Treasurer,
the Secretary or the Assistant Secretary of the Company and to apply to any such
officer for instructions (which instructions will be promptly given in writing
when requested), and the Warrant Agent shall not be liable for any action taken
or suffered to be taken by it in good faith in accordance with the instructions
of any such officer, except for its own gross negligence or willful misconduct,
but in its discretion the Warrant Agent may in lieu of such instructions accept
other evidence of such or may require such further or additional evidence as it
may deem reasonable. Any application by the Warrant Agent for written
instructions from the Company may, at the option of the Warrant Agent, set forth
in writing any action proposed to be taken or omitted by the Warrant Agent under
this Agreement and the date on and/or after which such action shall be taken or
such omission shall be effective. The Warrant Agent shall not be liable for any
action taken by, or omission of, the Warrant Agent in accordance with a proposal
included in such application on or after the date specified in such application
(which date shall not be less than three business days after the date any
officer of the Company actually receives such application, unless any such
officer shall have consented in writing to any earlier date) unless prior to
taking any such action (or the effective date in the case of an omission), the
Warrant Agent shall have received written instructions in response to such
application specifying the action to be taken or omitted.

          The Warrant Agent may execute and exercise any of the rights and
powers vested in it under this Agreement or perform any duty under this
Agreement either itself or by or through its attorneys, agents or employees,
provided reasonable care has been exercised in the selection of any such
attorney, agent or employee.  The Warrant Agent shall not be under any
obligation or duty to institute, appear in or defend any action, suit or legal
proceeding in respect of this Agreement, unless first indemnified to its
satisfaction, but this provision shall not affect the power of the Warrant Agent
to take such action as the Warrant Agent may consider proper, whether with or
without such indemnity.  The Warrant Agent shall promptly notify the Company in
writing of any claim made or action, suit or proceeding instituted against or
arising out of or in connection with this Agreement.  No provision of this
Agreement shall require the Warrant Agent to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
under this Agreement or in the exercise of its rights if there shall be
reasonable grounds for believing that repayment of such funds or adequate
indemnification against such risk or liability is not reasonably assured to it.

          The Company will perform, execute, acknowledge and deliver or cause to
be performed, executed, acknowledged and delivered all such further acts,
instruments and assurances as may reasonably be required by the Warrant Agent in
order to enable it to carry out or perform its duties under this Agreement.

<PAGE>


              The Warrant Agent shall act solely as agent of the Company under
this Agreement. The Warrant Agent shall not be liable except for the failure to
perform such duties as are specifically set forth in this Agreement, and no
implied covenants or obligations shall be read into this Agreement against the
Warrant Agent, whose duties and obligations shall be determined solely by the
express provisions of this Agreement.

Section 7.02  Right to Consult Counsel

              The Warrant Agent may at any time consult with legal counsel of
its selection satisfactory to it (who may be legal counsel for the Company), and
the Warrant Agent shall incur no liability or responsibility to the Company or
to any Holder for any action taken, suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.

Section 7.03  Compensation and Reimbursement; Indemnification

              The Company agrees to pay to the Warrant Agent from time to time
compensation for all services rendered by it under this Agreement as the Company
and the Warrant Agent may agree from time to time in writing, and to reimburse
the Warrant Agent for reasonable expenses and disbursements incurred in
connection with the execution and administration of this Agreement (including
the reasonable compensation and the expenses of its counsel), and further agrees
to indemnify the Warrant Agent for, and to hold it harmless against, any and all
loss, liability, damage, claim or expense incurred without gross negligence, bad
faith or willful misconduct on its part, arising out of or in connection with
the acceptance and administration of this Agreement, including the costs and
expenses of defending itself against any such claim or liability in connection
with the exercise or performance of any of its powers or duties under this
Agreement.  The provisions of this Section 7.03 shall survive the termination of
this Agreement.

Section 7.04  Warrant Agent May Hold Company Securities

              Except as may be limited by applicable law, the Warrant Agent and
any stockholder, director, officer or employee of the Warrant Agent may buy,
sell or deal in any of the Warrants or other securities of the Company or its
Affiliates or become pecuniarily interested in transactions in which the Company
or its Affiliates may be interested, or contract with or lend money to the
Company or its Affiliates or otherwise act as fully and freely as though it were
not the Warrant Agent under this Agreement. Nothing in this Agreement shall
preclude the Warrant Agent from acting in any other capacity for the Company or
for any other person.

Section 7.05  Resignation and Removal; Appointment of Successor

               (a)  No resignation or removal of the Warrant Agent and no
appointment of a successor warrant agent shall become effective until the
acceptance of appointment by the successor warrant agent as provided in this
Agreement. The Warrant Agent may resign its duties and be discharged from all
further duties and liability under this Agreement (except liability arising as a
result of the Warrant Agent's own gross negligence, bad faith or willful
misconduct)


                                       18
<PAGE>


after giving written notice to the Company. The Company may remove the Warrant
Agent upon written notice, and the Warrant Agent shall in like manner be
discharged from all further duties and liabilities under this Agreement, except
as set forth above. The Warrant Agent shall, at the Company's expense, cause to
be mailed (by first-class mail, postage prepaid) to each Holder of a Warrant at
its last address as shown on the register of the Company maintained by the
Warrant Agent a copy of said notice of resignation or notice of removal, as the
case may be. Upon such resignation or removal, the Company shall appoint in
writing a new warrant agent. If the Company shall fail to make such appointment
within a period of 30 days after it has been notified in writing of such
resignation by the resigning Warrant Agent or after such removal, then the
Company shall become Warrant Agent until a successor Warrant Agent has been
appointed, and the Holder of any Warrant may apply to any court of competent
jurisdiction for the appointment of a new warrant agent. Any new warrant agent,
whether appointed by the Company or by such a court, shall be a corporation
doing business under the laws of the United States, any state of the United
States, or the District of Columbia, in good standing and having a combined
capital and surplus of not less than $50,000,000. The combined capital and
surplus of any such new warrant agent shall be deemed to be the combined capital
and surplus as set forth in the most recent annual report of its condition
published by such warrant agent prior to its appointment, provided that such
reports are published at least annually pursuant to law or to the requirements
of a federal or state supervising or examining authority. After acceptance in
writing of such appointment by the new warrant agent, it shall be vested with
the same powers, rights, duties and responsibilities as if it had been
originally named as the Warrant Agent, without any further assurance,
conveyance, act or deed; but if for any reason it shall be necessary or
expedient to execute and deliver any further assurance, conveyance, act or deed,
the same shall be done at the expense of the Company and shall be legally and
validly executed and delivered by the resigning or removed Warrant Agent. Not
later than the effective date of any such appointment, the Company shall give
notice of the appointment to the resigning or removed Warrant Agent. Failure to
give any notice provided for in this Section, however, or any defect in such
notice, shall not affect the legality or validity of the resignation or removal
of the Warrant Agent or the appointment of a new warrant agent, as the case may
be.

          (b) Any corporation into which the Warrant Agent or any new warrant
agent may be merged or any corporation resulting from any consolidation to which
the Warrant Agent or any new warrant agent shall be a party or any person to
whom the Warrant Agent transfers substantially all of its corporate trust
business shall be a successor Warrant Agent under this Agreement without any
further act, provided that such corporation (i) would be eligible for
                                             -
appointment as successor to the Warrant Agent under the provisions of Section
7.05(a) or (ii) is a wholly-owned subsidiary of the Warrant Agent.  Any such
            --
successor Warrant Agent shall promptly cause notice of its succession as Warrant
Agent to be mailed (by first class mail, postage prepaid) to each Holder at such
Holder's last address as shown on the register maintained by the Warrant Agent
pursuant to Section 5.01.

                           COVENANTS OF THE COMPANY

Section 8.01  Reservation of Common Stock for Issuance on Exercise of Warrants;
Listing

              The Company will at all times reserve and keep available, free
from preemptive rights, out of its authorized but unissued Common Stock, solely
for the purpose of issuance upon exercise of Warrants as provided in this
Agreement, such number of shares of Common Stock as shall then be issuable upon
the exercise of all outstanding Warrants. The Company covenants that all shares
of Common Stock which shall be so issuable shall, upon such issuance, be duly
and validly issued and fully paid and nonassessable, and that upon issuance such
shares shall be listed on each national securities exchange or quotation system
(including the Nasdaq Stock Market), if any, on which any other shares of
outstanding Common Stock of the Company are then listed.

              The Company or the transfer agent for the Common Stock (the
"Transfer Agent") and every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of any of the Warrants as
provided in this Agreement will be irrevocably authorized and directed at all
times to reserve such number of authorized shares as shall be required for such
purpose. The Company will keep a copy of this Agreement on file with the
Transfer Agent and with every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants. The Warrant Agent is hereby irrevocably authorized
to requisition from time to time from such Transfer Agent the stock certificates
required to honor outstanding Warrants upon exercise in accordance with the
terms of this Agreement. The Company will supply such Transfer Agent with duly
executed certificates for such purposes and will provide or otherwise make
available any cash that may be payable as provided in Section 4.04. The Company
will furnish such Transfer Agent a copy of all notices of adjustment and related
certificates transmitted to each holder pursuant to Section 4.02.

Section 8.02  Agreements Respecting Warrants

              The Company agrees that it will not enter into any agreement or
instrument which would preclude the exercise of the Warrants for shares of
Common Stock.

Section 8.03  Registration under Federal Securities Laws

              The Company has registered under the Securities Act all of the
Warrants and the Common Stock issuable upon exercise of the Warrants.  The
Company shall use all reasonable efforts to maintain such effectiveness
continually until the close of business on the Expiration Date or such other
date on which the Warrants terminate and become void prior to the Expiration
Date.

Section 9.01  Money and Other Property Deposited with the Warrant Agent

              Any money, securities or other property which at any time shall be
deposited by the Company or on its behalf with the Warrant Agent pursuant to
this Agreement shall be assigned, transferred and set over to the Warrant Agent
in trust for the purpose for which such moneys, securities or other property
shall have been deposited; but such moneys, securities or other property need
not be segregated from other funds, securities or other property of the Warrant
Agent except to the extent required by law.  The Warrant Agent shall distribute
any money deposited with it for payment and distribution to any Holder by
mailing by first-class mail a check in such amount as is appropriate, to such
Holder at the address shown on the Warrant register maintained pursuant to
Section 5.01, or as it may be otherwise directed in writing by such Holder, upon
surrender of such Holder's Warrants.  Any money or other property deposited with
the Warrant Agent for payment and distribution to any Holder that remains
unclaimed for two years, less one day, after the date the money was deposited
with the Warrant Agent shall be paid to the Company upon its request.

Section 9.02  Payment of Taxes

              The Company will pay all taxes and other governmental charges that
may be imposed on the Company or the Warrant Agent in respect of any issuance or
delivery of Common Stock upon the exercise of Warrants. The Company will not be
required, however, to pay any tax or other charge imposed in connection with any

                        ICF KAISER INTERNATIONAL, INC.


     This certifies that ___________________________________, or registered
assigns, is the registered holder of the number of Warrants set forth above (the

share, of the Company (the "Common Stock") for consideration equal to the

The Warrants evidenced by this Warrant Certificate shall not be exercisable
after and shall terminate and become void as of the close of business on
December 31, 2004 (the "Expiration Date") or as of the closing of any Non-
Surviving Combination, if earlier.

     This Warrant Certificate is issued under and in accordance with a Warrant
Agreement dated as of _________ __, 1999 (the "Warrant Agreement"), between the
Company and _________________, as warrant agent (the "Warrant Agent", which term
includes any successor Warrant Agent under the Warrant Agreement), and is
subject to the terms and provisions contained in the Warrant Agreement, to all
of which terms and provisions the Holder of this Warrant Certificate consents by
acceptance of this Warrant Certificate.  The Warrant Agreement is incorporated
in this Warrant Certificate by reference and made a part of this Warrant
Certificate.  Reference is hereby made to the Warrant Agreement for a full
statement of the respective rights, limitations of rights, duties and
obligations of the Company, the Warrant Agent and the Holders of the Warrants.

     If the Company proposes, prior to the Expiration Date, to enter into a
merger, consolidation, sale of assets or other business combination with one or
more persons (other than a wholly-owned subsidiary of the Company) in which
consideration (other than Common Equity Securities) is distributed to the
holders of Common Stock in exchange for all or substantially all of their equity
interest in the Company (a "Non-Surviving Combination"), the Company shall give
written notice to the Holders promptly after an agreement is reached but in no
event less than 30 days prior to the closing of any such transaction.  In the
event the Company enters into a Non-Surviving Combination, upon payment of the
Purchase Price prior to the Expiration Date, the Holder of this Warrant
Certificate will be entitled to receive the shares of stock or other securities
or other property (including any money) of the surviving entity in such Non-
Surviving Combination as the Holder would have received had the Holder exercised
its Warrants immediately prior to such Non-Surviving Combination (or, if
applicable, the record date for that transaction).

     In order to exercise a Warrant, the registered Holder of this Warrant
Certificate must surrender this Warrant Certificate at the office of the Warrant
Agent, with the Exercise Subscription Form on the reverse side duly executed by

     This Warrant Certificate and all rights under this Warrant Certificate are
transferable by the registered Holder of this Warrant Certificate, in whole or
in part, on the register maintained by the Warrant Agent, upon surrender of this
Warrant Certificate for registration of transfer at the office of the Warrant
Agent maintained for such purpose, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Warrant Agent
duly executed by, the registered Holder of this Warrant Certificate or its
attorney duly authorized in writing, with signature guaranteed as specified in
the attached Form of Transfer.  Upon any partial transfer, the Company will
issue and deliver to such Holder a new Warrant Certificate or Certificates with
respect to any portion not so transferred.  No service charge shall be made for
any registration of transfer or exchange of Warrant Certificates, but the
Company may require payment by the Holder of a sum sufficient to cover any tax
or other governmental charge payable in connection with any partial transfer.

     All shares of Common Stock issuable by the Company upon the exercise of the
Warrants shall, upon such issue, be duly and validly issued and fully paid and
nonassessable, and upon issuance such shares shall be listed on each national
securities exchange or quotation system (including the Nasdaq Stock Market), if
any, on which any other shares of outstanding Common Stock are then listed.

     Each taker and holder of this Warrant Certificate, by taking or holding the
same, consents and agrees that the holder of this Warrant Certificate when duly
endorsed in blank may be treated by the Company, the Warrant Agent and all other
persons dealing with this Warrant Certificate as the absolute owner of the
related Warrants for any purpose and as the person entitled to exercise the
rights represented by this Warrant Certificate, or to the transfer of such
Warrants on the register of the Company maintained by the Warrant Agent, any
notice to the contrary notwithstanding, but until such transfer on such
register, the Company and the Warrant Agent may treat the registered Holder of
such Warrants as the owner for all purposes.

     The number of shares of Common Stock issuable upon exercise of the Warrants
is subject to adjustment in certain events, including (i) stock dividends, stock
                                                       -
splits and reclassification affecting the Common Stock, (ii) the issuance of
                                                         --
certain rights, warrants or options, or convertible or exchangeable securities,
to the holders of Common Stock entitling them to acquire Common Stock at a price
per share lower than its then market value and (iii) sales by the Company of
                                                ---
Common Stock at a price per share lower than its then market value.

     The Warrants do not entitle any Holder to any of the rights of a
stockholder of the Company.

     This Warrant Certificate and the Warrant Agreement are subject to amendment
as provided in the Warrant Agreement.

   The undersigned acknowledges receipt of the Prospectus, dated _____________,
1999 (the "Prospectus"), of ICF Kaiser International, Inc., a Delaware
corporation ("Kaiser"), relating to:

 .  the offer of Kaiser, upon the terms and subject to the conditions set forth
   in the Prospectus and in this Letter of Transmittal and Consent Form and the
   instructions hereto, to purchase for cash on a pro rata basis a total of up
   to $40 million aggregate principal amount of its 12% senior subordinated
   notes due 2003 (the "Asset Sale Offer");

 .  the offer of Kaiser, upon the terms and subject to the conditions set forth
   in the Prospectus and in this Letter of Transmittal and Consent Form and the
   instructions hereto, to exchange 2,600,000 shares of Kaiser's convertible
   preferred stock (the "Preferred Stock"), warrants to purchase approximately
   15% of Kaiser's common stock on a fully diluted basis (the "Warrants") and up
   to $25 million principal amount of Kaiser's 13% Senior Notes due 2002 (the
   "New Notes") (collectively, the "Exchange Offer") for all 12% Senior
   Subordinated Notes due 2003 (the "Old Notes") outstanding following the
   purchase of the Old Notes in the Asset Sale Offer; and

 .  the solicitation by Kaiser (the "Consent Solicitation") of consents (the
   "Consents"), upon the terms and subject to the conditions set forth in the
   Prospectus and in this Letter of Transmittal and Consent Form and the
   instructions hereto, from registered holders of the Old Notes to:

   .  certain amendments (the "Proposed Amendments") to the indenture governing
      the Old Notes, as more fully described in the Prospectus, and

   .  an instruction to the trustee under the indenture governing the Old Notes
      not to interfere with the Asset Sale Offer, Exchange Offer and Consent
      Solicitation (the "Instruction to Trustee").

   THE ASSET SALE OFFER/EXCHANGE OFFER/CONSENT SOLICITATION WILL EXPIRE AT 5:00
P.M., NEW YORK CITY TIME, ON __________, 1999 (THE "EXPIRATION DATE"), UNLESS
EXTENDED.  HOLDERS WHO WISH TO BE ELIGIBLE TO RECEIVE CASH PURSUANT TO THE ASSET
SALE OFFER OR RECEIVE PREFERRED STOCK, WARRANTS AND NEW NOTES PURSUANT TO THE
EXCHANGE OFFER MUST VALIDLY TENDER THEIR OLD NOTES TO THE
PAYING/EXCHANGE/SOLICITATION AGENT BY 5:00 P.M. ON THE EXPIRATION DATE.

   This Letter of Transmittal and Consent Form is to be used either (a) if Old
Notes are to be physically delivered to the Paying/Exchange/Solicitation Agent
or (b) if delivery of Old Notes is to be made by book-entry transfer to the
account maintained by the Paying/Exchange/Solicitation Agent at The Depository
Trust Company ("DTC" or the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in the Prospectus under the caption "Procedures for
Tendering Old Notes in the Exchange Offer, Tendering Old Notes in the Asset Sale
Offer and Tendering Consents in the Consent Solicitation."  Delivery of
documents to the Book-Entry Transfer Facility does not constitute delivery to
the Paying/Exchange/Solicitation Agent.

   Holders whose Old Notes are not available or who cannot deliver their Old
Notes and all other documents required hereby to the
Paying/Exchange/Solicitation Agent by 5:00 p.m. on the Expiration Date
nevertheless may tender their Old Notes in accordance with the guaranteed
delivery procedures set forth in Instruction 1 hereto.

   The Asset Sale Offer/Exchange Offer/Consent Solicitation is not being made to
(nor will the surrender of Old Notes or Consents be accepted from or on behalf
of) holders in any jurisdiction in which the making or accepting of the Asset
Sale Offer/Exchange Offer/Consent Solicitation would not be in compliance with
the laws of such jurisdiction.

   All capitalized terms used herein and not defined herein shall have the
meanings ascribed to them in the Prospectus.

NOTE: SIGNATURE MUST BE PROVIDED BELOW.  PLEASE READ THE ACCOMPANYING
      INSTRUCTIONS CAREFULLY.

Ladies and Gentlemen:

  Upon the terms and subject to the conditions of the Asset Sale Offer/Exchange
Offer/Consent Solicitation, the undersigned hereby tenders to Kaiser the
principal amount of Old Notes and/or Consents indicated in the box entitled
"Description of Old Notes and Consents Tendered" in respect of the Old Notes and
Consents indicated above.  Subject to, and effective upon, the acceptance of the
Old Notes and Consents tendered hereby, the undersigned hereby irrevocably
sells, assigns and transfers to or upon the order of Kaiser all right, title and
interest in and to such Old Notes, and hereby irrevocably constitutes and
appoints the Paying/Exchange/Solicitation Agent the true and lawful agent and
attorney-in-fact of the undersigned (with full knowledge that said
Paying/Exchange/Solicitation Agent also acts as the agent of Kaiser and as
Trustee under the indenture governing the Old Notes) with respect to Old Notes
and Consents, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest) to (a) deliver
certificates representing such Old Notes, deliver the Consents contained herein,
and to deliver all accompanying evidences of transfer and authenticity to or
upon the order of Kaiser upon receipt by the Paying/Exchange/Solicitation Agent,
as the undersigned's agent, of the cash, Preferred Stock, Warrants and New Notes
to which the undersigned is entitled upon the acceptance by Kaiser of such Old
Notes and Consents pursuant to the Asset Sale Offer/Exchange Offer/Consent
Solicitation, (b) receive all benefits and otherwise to exercise all rights of
beneficial ownership of such Old Notes, all in accordance with the terms of the
Asset Sale Offer/Exchange Offer/Consent Solicitation, and (c) present such Old
Notes for transfer on the register for such Old Notes.

  THE ASSET SALE OFFER/EXCHANGE OFFER/CONSENT SOLICITATION IS NOT BEING MADE TO,
NOR WILL TENDERS OF OLD NOTES AND CONSENTS BE ACCEPTED FROM OR ON BEHALF OF,
HOLDERS OF THE OLD NOTES IN ANY JURISDICTION IN WHICH THE MAKING OF THE OFFER OR
ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE WITH THE LAWS OF SUCH JURISDICTION
OR WOULD OTHERWISE NOT BE IN COMPLIANCE WITH ANY PROVISION OF ANY APPLICABLE
SECURITIES LAW.

  The undersigned understands and acknowledges that Kaiser reserves the right,
in its sole discretion, to purchase or make offers for any Old Notes that remain
outstanding subsequent to the Expiration Date or to terminate the Asset Sale
Offer/Exchange Offer/Consent Solicitation and, to the extent permitted by
applicable law, purchase Old Notes in the open market, in privately negotiated
transactions or otherwise.  The terms of any such purchases or offers will
differ from the terms of the Asset Sale Offer/Exchange Offer/Consent
Solicitation.

  The undersigned hereby represents and warrants that (a) the undersigned
accepts the terms and conditions of the Asset Sale Offer/Exchange Offer/Consent
Solicitation, (b) the undersigned has full power and authority to tender,
exchange, assign and transfer the Old Notes tendered hereby, and when the same
are accepted for exchange by Kaiser, Kaiser will acquire good and unencumbered
title thereto, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim or right, and (c) the
undersigned has full power and authority to tender the Consents tendered hereby.
The undersigned will, upon request, execute and deliver any additional documents
deemed by the Paying/Exchange/Solicitation Agent or Kaiser to be necessary or
desirable to complete the sale, assignment and transfer of the Old Notes
tendered hereby.

  The undersigned agrees that all authority conferred or agreed to be conferred
by this Letter of Transmittal and Consent Form and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned.

  The undersigned understands that tenders of the Old Notes and Consents
pursuant to any one of the procedures described in the Prospectus and in the
instructions hereto will constitute a binding agreement between the undersigned
and Kaiser in accordance with the terms and subject to the conditions of the
Asset Sale Offer/Exchange Offer/Consent Solicitation.  The undersigned
recognizes that, under certain circumstances set forth in the Prospectus, Kaiser
may not be required to accept any of the Old Notes or Consents tendered.  The
undersigned agrees that tenders of Old Notes in the Asset Sale Offer and/or the
Exchange Offer may not be withdrawn once made, and also agrees that tenders of
Consents may only be revoked under the circumstances described in the
Prospectus.

  Unless otherwise indicated herein under the box entitled "Special Issuance
Instructions" below, Preferred Stock, Warrants and New Notes, and Old Notes not
validly tendered or accepted, will be issued in the name of the undersigned.
Similarly, unless otherwise indicated under the box entitled "Special Delivery
Instructions" below, Preferred Stock, Warrants and New Notes, and Old Notes not
validly tendered or accepted, will be delivered to the undersigned at the

                                      -5-
<PAGE>


address shown in such box below the signature of the undersigned. The
undersigned recognizes that Kaiser has no obligation pursuant to the "Special
Issuance Instructions" to transfer any Old Notes from the name of the registered
holder thereof if Kaiser does not accept any of the principal amount of such Old
Notes so tendered.

  All questions as to the validity, form, eligibility (including time of
receipt) and revocation of the Consents will be determined by Kaiser in its sole
discretion, which determination will be final and binding.  Kaiser reserves the
absolute right to reject any and all Old Notes and Consents not properly
tendered or any Old Notes and Consents that Kaiser's acceptance of which would,
in the opinion of counsel for Kaiser, be unlawful.  Kaiser also reserves the
right to waive any irregularities or conditions of tender as to particular Old
Notes and Consents.  Kaiser's interpretation of the terms and conditions of the
Asset Sale Offer/Exchange Offer/Consent Solicitation (including the instructions
in this Letter of Transmittal and Consent Form) will be final and binding on all
parties.  Unless waived, any defects or irregularities in connection with
tenders of Old Notes and Consents must be cured within such time as Kaiser shall
determine.  Neither Kaiser, the Paying/Exchange/Solicitation Agent nor any other
person shall be under any duty to give notification of defects or irregularities
with respect to tenders of Old Notes and Consents, nor shall any of them incur
any liability for failure to give such notification.  Tenders of Old Notes and
Consents will not be deemed to have been made until such irregularities have
been cured or waived.  Any Old Notes and Consents received by the
Paying/Exchange/Solicitation Agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned without cost to such holder by the Paying/Exchange/Solicitation Agent
to the tendering holders of Old Notes and Consents, unless otherwise provided in
this Letter of Transmittal and Consent Form, as soon as practicable following
the Expiration Date.

                                 INSTRUCTIONS

                FORMING PART OF THE TERMS AND CONDITIONS OF THE
              Asset Sale Offer/Exchange Offer/Consent Solicitation

  1.  Delivery of this Letter of Transmittal and Consent Form and Certificates;
Guaranteed Delivery Procedures.  To be effectively tendered pursuant to the
Asset Sale Offer/Exchange Offer/Consent Solicitation, the Old Notes, together
with a properly completed Letter of Transmittal and Consent Form (or facsimile
thereof), duly executed by the registered holder thereof, and any other
documents required by this Letter of Transmittal and Consent Form, must be
received by the Paying/Exchange/Solicitation Agent at one of its addresses set
forth on the first page of this Letter of Transmittal and Consent Form.  If the
beneficial owner of any Old Notes is not the registered holder, then such person
may validly tender his or her Old Notes and Consents only by obtaining and
submitting to the Paying/Exchange/Solicitation Agent a properly completed Letter
of Transmittal and Consent Form from the registered holder.  OLD NOTES AND
CONSENTS SHOULD BE DELIVERED ONLY TO THE PAYING/EXCHANGE/SOLICITATION AGENT AND
NOT TO KAISER OR TO ANY OTHER PERSON.

THE METHOD OF DELIVERY OF OLD NOTES AND CONSENTS AND ALL OTHER REQUIRED
DOCUMENTS TO THE PAYING/EXCHANGE/SOLICITATION AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER.

  SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY TO THE
PAYING/EXCHANGE/SOLICITATION AGENT BY 5:00 P.M., NEW YORK CITY TIME, ON THE
EXPIRATION DATE.

  If a holder desires to tender Old Notes and Consents and such holder's Old
Notes are not immediately available, or if time will not permit such holder's
Letter of Transmittal and Consent Form, Old Notes, or other required documents
to reach the Paying/Exchange/Solicitation Agent on or before the Expiration
Date, or if time will not permit the holder to complete the procedure for book-
entry transfer, such holder's tender may be effected if:

     (a)  the tender is made through an Eligible Institution (as defined);

     (b)  prior to the Expiration Date, the Paying/Exchange/Solicitation Agent
  receives from such Eligible Institution a properly completed and duly executed
  Notice of Guaranteed Delivery (by facsimile transmission, mail or hand
  delivery) setting forth the name and address of the holder of the Old Notes,
  the certificate number or numbers of such Old Notes and the principal amount
  of Old Notes tendered in the Asset Sale Offer and/or Exchange Offer, stating
  that the tender is being made thereby, and guaranteeing that, within three
  business days after the Expiration Date, the Letter of Transmittal and Consent
  Form (or facsimile thereof) together with the certificate(s) representing the
  Old Notes to be tendered in proper form for transfer or a Book-Entry
  Confirmation, as the case may be, and any other documents required by the
  Letter of Transmittal and Consent Form will be deposited by the Eligible
  Institution with the Paying/Exchange/Solicitation Agent; and

     (c)  such properly completed and executed Letter of Transmittal and Consent
  Form (or facsimile thereof), together with the certificate(s) representing all
  tendered Old Notes in proper form for transfer and all other documents
  required by the Letter of Transmittal and Consent Form, or confirmation of a
  book-entry transfer of these Old Notes into the Paying/Exchange/Solicitation
  Agent's account at DTC, are received by the Paying/Exchange/Solicitation Agent
  within three business days after the Expiration Date.

  Any holder who wishes to tender Old Notes pursuant to the guaranteed delivery
procedures described above must ensure that the Paying/Exchange/Solicitation
Agent receives the Notice of Guaranteed Delivery and Letter of Transmittal and
Consent Form relating to these Old Notes prior to 5:00 p.m., New York City time,
on the Expiration Date.

  2.  Acceptance of Old Notes for Purchase or Exchange and Acceptance of
Consents.  Upon satisfaction or waiver of all the conditions to the Exchange
Offer, Kaiser will accept any and all Old  Notes that are properly tendered in
the Exchange Offer, Old Notes properly tendered in the Asset Sale Offer and
Consents properly tendered in the Consent Solicitation prior to 5:00 p.m., New
York City time, on the Expiration Date.  The Preferred Stocks, Warrants and New
Notes issued pursuant to the Exchange Offer will be delivered promptly after
acceptance of the Old Notes.  For purposes of the Exchange Offer, Kaiser will be
deemed to have accepted validly tendered Old Notes, when, as, and if Kaiser has
given oral or written notice to the Paying/Exchange/Solicitation Agent.


                                      -10-
<PAGE>


  3.  Revocation of Consents.  Tendered Consents may be revoked at any time
prior to 5:00 p.m., New York City time on the Expiration Date, unless previously
accepted.

  To be effective, a written or facsimile transmission notice of revocation must
(a) be received by the Paying/Exchange/Solicitation Agent at one of its
addresses set forth on the first page of this Letter of Transmittal and Consent
Form prior to 5:00 p.m., New York City time, on the Expiration Date, unless
previously accepted, (b) specify the name of the person who tendered the
Consents, (c) contain the description of the Consents to be revoked and (d) be
signed by the holder of the Old Notes in the same manner as the original
signature appears on this Letter of Transmittal and Consent Form (including any
required signature guarantees).  The signature(s) on the notice of revocation
must be guaranteed by an Eligible Institution unless such Consents have been
tendered (a) by a registered holder of Old Notes who has not completed either
the box entitled "Special Issuance Instructions" or the box entitled "Special
Delivery Instructions" on this Letter of Transmittal and Consent Form or (b) for
the account of an Eligible Institution.  All questions as to the validity, form
and eligibility (including time of receipt) of such revocation notices shall be
determined by Kaiser, whose determination shall be final and binding on all
parties.  If the Consents to be revoked have been delivered or otherwise
identified to the Paying/Exchange/Solicitation Agent, a signed notice of
revocation is effective immediately upon receipt by the
Paying/Exchange/Solicitation Agent of a written or facsimile transmission notice
of revocation even if physical release is not yet effected.  Revocations may not
be rescinded, and any Consents revoked will thereafter be deemed not validly
tendered for purposes of the Asset Sale Offer/Exchange Offer/Consent
Solicitation.  However, properly revoked Consents may be retendered at any time
on or prior to the applicable Expiration Date.

  4.  Signatures on this Letter of Transmittal and Consent Form, Proxies and
Endorsements; Guarantee of Signatures.  If this Letter of Transmittal and
Consent Form is signed by the registered holder(s) of the Old Notes tendered
hereby, the signature must correspond exactly with the name(s) as written on the
face of the certificates without any change whatsoever.

  If any Old Notes tendered hereby are owned of record by two or more joint
owners, all such owners, must sign this Letter of Transmittal and Consent Form.

  If any Old Notes tendered hereby are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this Letter of Transmittal and Consent Form as there are different
registrations of certificates.

  When this Letter of Transmittal and Consent Form is signed by the registered
holder or holders specified herein and tendered hereby, no endorsements of
certificates or separate proxies are required unless Preferred Stocks, Warrants
and New Notes are to be issued, or certificates for any untendered principal
amount of Old Notes are to be reissued, to a person other than the registered
holder.

  If this Letter of Transmittal and Consent Form is signed by a person other
than the registered holder(s), then the tendered Old Notes and Consents must
either (a) be endorsed by the registered holder(s), with the signature
guaranteed by an Eligible Institution or (b) be accompanied by a proxy, duly
executed by the registered holder(s), with the signature on such proxy
guaranteed by an Eligible Institution.  Such proxy must be delivered with this
Letter of Transmittal and Consent Form.

  If this Letter of Transmittal and Consent Form or a Notice of Guaranteed
Delivery or any certificates are signed by trustees, executors, administrators,
guardians, attorneys-in-fact, officers of corporations or others acting in a
fiduciary or representative capacity, such persons should so indicate when
signing, and unless waived by Kaiser, evidence satisfactory to Kaiser of their
authority so to act must be submitted with this Letter of Transmittal and
Consent Form.

  Except as described below, signatures on this Letter of Transmittal and
Consent Form or a notice of revocation, as the case may be, must be guaranteed
by an Eligible Institution.  Signatures on this Letter of Transmittal and
Consent Form or a notice of revocation, as the case may be, need not be
guaranteed if the Old Notes tendered and Consents pursuant hereto are tendered
(a) by a registered holder of Old Notes who has not completed either the box
entitled "Special Issuance Instructions" or the box entitled "Special Delivery
Instructions" on this Letter of Transmittal and Consent Form or (b) for the
account of an Eligible Institution.  In the event that signatures on this Letter
of Transmittal and Consent Form or a notice of revocation, as the case may be,
are required to be guaranteed, such guarantee must be by a firm which is a
member of a registered national securities exchange, or a member of the National
Association of Securities Dealers, Inc., or by a commercial bank or trust
company having an office or correspondent in the United States, or otherwise an
"eligible guarantor institution" within the meaning of Rule 17Ad-15 under the
Securities Exchange Act of 1934 (each, an "Eligible Institution").


                                      -11-
<PAGE>


  Endorsements on certificates for Old Notes or signatures on proxies required
by this Instruction 4 must be guaranteed by an Eligible Institution.

  5.  Special Issuance and Delivery Instructions.  Tendering holders should
indicate in the applicable box the name and address to which certificates for
the Preferred Stock, Warrants and New Notes and/or substitute certificates
evidencing Old Notes for the principal amounts not exchanged are to be issued or
sent, if different from the name and address of the person signing this Letter
of Transmittal and Consent Form.  In the case of issuance in a different name,
the employer identification or social security number of the person named must
also be indicated.  If no such instructions are given, any Old Notes not
exchanged will be returned to the name and address of the person signing this
Letter of Transmittal and Consent Form.

  6.  Beneficial Owners.  Any beneficial owner of Old Notes whose notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wants to tender Old Notes in the Exchange Offer or in the
Asset Sale Offer or tender Consents in the Consent Solicitation, should contact
the registered holder promptly and instruct the registered holder to tender on
the beneficial owner's behalf.  If a beneficial owner wishes to tender directly,
the beneficial owner must, prior to completing and executing the Letter of
Transmittal and Consent Form and tendering Old Notes and Consents, make
appropriate arrangements to register ownership of the notes in the beneficial
owner's name.  Beneficial owners should be aware that the transfer of registered
ownership may take considerable time.

  7.  Tax Identification Number; Withholding.  A holder of Old Notes whose Old
Notes are accepted must provide Kaiser with the holder's correct taxpayer
identification number, which, in the case of a holder who is an individual, is
his or her social security number, or otherwise establish an exemption from
backup withholding.  If Kaiser is not provided with the correct taxpayer
identification number, the tendering holder of Old Notes may be subject to a $50
penalty imposed by the Internal Revenue Service (the "IRS"), and the cash
received pursuant to the Asset Sale Offer, together with any payments made on
account of the Preferred Stock, Warrants and New Notes acquired pursuant to the
Exchange Offer, may be subject to backup withholding in an amount equal to 31%
of any such cash or payments.

  To prevent backup withholding, each tendering holder of Old Notes subject to
backup withholding must provide its correct taxpayer identification number by
completing the Substitute Form W-9 provided in this Letter of Transmittal and
Consent Form, including the certifications contained therein.  Certain tendering
holders of Old Notes (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding requirements.
A foreign individual and other exempt holders (i.e., corporations) should
certify to such exempt status on the Substitute Form W-9 provided in this Letter
of Transmittal and Consent Form.

  8.  Transfer Taxes.  Holders tendering pursuant to the Asset Sale
Offer/Exchange Offer/Consent Solicitation will not be obligated to pay brokerage
commissions or fees or to pay transfer taxes with respect to their tender under
the Asset Sale Offer/Exchange Offer/Consent Solicitation unless the box entitled
"Special Issuance Instructions" in this Letter of Transmittal and Consent Form
has been completed, or unless the Preferred Stock, Warrants and New Notes are to
be issued to any person other than the holder of the Old Notes tendered.  Kaiser
will pay all other charges or expenses in connection with the Asset Sale
Offer/Exchange Offer/Consent Solicitation.  If holders tender Old Notes and the
Asset Sale Offer/Exchange Offer/Consent Solicitation is not consummated,
certificates representing the Old Notes will be returned to the holders at
Kaiser's expense.

  Except as provided in this Instruction 8, it will not be necessary for
transfer tax stamps to be affixed to the certificate(s) specified in this Letter
of Transmittal and Consent Form.

  9.  Inadequate Space.  If the space provided herein is inadequate, the
aggregate principal amount of the Old Notes and Consents being tendered and the
certificate numbers (if available) should be listed on a separate schedule
attached hereto and separately signed by all parties required to sign this
Letter of Transmittal and Consent Form.

  10. Mutilated, Lost, Stolen or Destroyed Old Notes.  Any holder whose Old
Notes have been mutilated, lost, stolen or destroyed should contact the
Paying/Exchange/Solicitation Agent at the address indicated above for further
instructions.

  11. Request for Assistance or Additional Copies.  Requests for assistance or
additional copies of the Prospectus or this Letter of Transmittal and Consent
Form may be obtained from the Paying/Exchange/Solicitation Agent at its
telephone number set forth on the first page of this Letter of Transmittal and
Consent Form.

                                   to backup withholding, do not cross out item (2). If you are exempt from backup withholding,

the purchase of the Old Notes in the Asset Sale Offer, and in connection with
the solicitation (the "Consent Solicitation") of consents (the "Consents") upon
the terms and subject to the conditions set forth in the Prospectus and Letter
of Transmittal and Consent Form.

     Consummation of the Asset Sale Offer/Exchange Offer/Consent Solicitation is
subject to certain conditions described in the Prospectus.  Capitalized terms
used herein but not defined shall have the meanings ascribed to them in the
Prospectus.

     WE ARE THE REGISTERED HOLDER OF OLD NOTES HELD BY US FOR YOUR ACCOUNT.  A
TENDER OF ANY SUCH OLD NOTES CAN BE MADE ONLY BY US AS THE REGISTERED HOLDER AND
PURSUANT TO YOUR INSTRUCTIONS.  THE LETTER OF TRANSMITTAL AND CONSENT FORM IS
FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED BY YOU TO TENDER
OLD NOTES HELD BY US FOR YOUR ACCOUNT.

     Accordingly, we request instructions as to whether you wish us to tender
any or all such Old Notes held by us for your account or whether you wish us to
tender consents pursuant to the terms and conditions set forth in the Prospectus

<PAGE>


and the Letter of Transmittal and Consent Form.  We urge you to read carefully
the Prospectus and the Letter of Transmittal and the Consent Form before
instructing us to tender your Old Notes or Consents.

     Your instructions to us should be forwarded as promptly as possible in
order to permit us to tender Old Notes or Consents on your behalf in accordance
with the provisions of the Asset Sale Offer/Exchange Offer/Consent Solicitation.
THE ASSET SALE OFFER/EXCHANGE OFFER/CONSENT SOLICITATION WILL EXPIRE AT 5:00
P.M., NEW YORK CITY TIME ON ______________ (THE "EXPIRATION DATE"), UNLESS
EXTENDED.  Tenders of Old Notes may not be withdrawn once made.  Tenders of
Consents may only be revoked under the circumstances described in the Prospectus
and the Letter of Transmittal and Consent Form.

     Your attention is directed to the following:

          1.  The Exchange Offer is for the entire aggregate principal amount of
     outstanding Old Notes following the Asset Sale Offer.

          2.  Consummation of the Asset Sale Offer/Exchange Offer/Consent
     Solicitation is conditioned upon the conditions set forth in the Prospectus
     under the caption  "Conditions of the Exchange Offer."

          3.  Tendering holders may revoke their Consent at any time until the
     Expiration Date.

          4.  Any transfer taxes incident to the transfer of Old Notes from the
     tendering holder to Kaiser will be paid by Kaiser, except as provided in
     the Prospectus and the instructions to the Letter of Transmittal and
     Consent Form.

          5.  The Asset Sale Offer/Exchange Offer/Consent Solicitation is not
     being made to (nor will the surrender of Old Notes be accepted from or on
     behalf of) holders of Old Notes in any jurisdiction in which the making or
     acceptance of the Asset Sale Offer/Exchange Offer/Consent Solicitation
     would not be in compliance with the laws of such jurisdiction.

          6.  The acceptance of Old Notes validly tendered, the acceptance of
     Consents validly tendered and not revoked and the payment of cash and the
     issuance of Preferred Stock, Warrants and New Notes to the tendering Old
     Note holders will be made as promptly as practicable after the Expiration
     Date.  Subject to rules promulgated pursuant to the Securities Exchange Act
     of 1934, as amended (the "Exchange Act"), Kaiser, however, expressly
     reserves the right to delay acceptance of any of the Old Notes or Consents
     or to terminate the Asset Sale Offer/Exchange Offer/Consent Solicitation if
     any of the conditions set forth in the Prospectus under the caption
     "Conditions of the Exchange Offer" shall not have been satisfied or waived
     by Kaiser.

          7.  Kaiser expressly reserves the right, in its sole discretion,

              .  to delay accepting any Old Notes or Consents,

              .  to extend the Asset Sale Offer/Exchange Offer/Consent
                 Solicitation,

              .  to amend the terms of the Asset Sale Offer/Exchange
                 Offer/Consent Solicitation, or

              .  to terminate the Asset Sale Offer/Exchange Offer/Consent
                 Solicitation.

     Any delay, extension, amendment or termination will be followed as promptly
     as practicable by oral or written notice to the
     Paying/Exchange/Solicitation Agent and a public announcement thereof. In
     the case of an extension, such public announcement shall include disclosure
     of the approximate number of Old Notes and Consents deposited to date and
     shall be made prior to 9:00 a.m., New York City time, on the next business
     day after the previously scheduled Expiration Date. Without limiting the
     manner in which Kaiser may choose to make a public announcement of any
     extension, amendment or termination of the Asset Sale Offer/Exchange
