   SERIES B, WHICH HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
   AMENDED, FOR EACH $1,000 IN PRINCIPAL AMOUNT OF ITS OUTSTANDING 12% SENIOR
                            NOTES DUE 2003, SERIES A
 
 THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON    , 1997,
                                UNLESS EXTENDED.
 
                                  ----------
 
  ICF Kaiser International, Inc. ("ICF Kaiser" or the "Company") hereby offers
to exchange (the "Exchange Offer") up to $15,000,000 in aggregate principal
amount of its new 12% Senior Notes due 2003, Series B (the "Exchange Notes"),
for up to $15,000,000 in aggregate principal amount of its outstanding 12%
Senior Notes due 2003, Series A (the "Old Notes" and, together with the
Exchange Notes, the "Notes"), that were issued and sold in a transaction exempt
from registration under the Securities Act of 1933, as amended (the "Securities
Act").
 
  The terms of the Exchange Notes are substantially identical (including
principal amount, interest rate, maturity, security and ranking) to the terms
of the Old Notes for which they may be exchanged pursuant to the Exchange
Offer, except that the Exchange Notes (i) are freely transferable by holders
thereof (except as provided below) and (ii) are not entitled to certain
registration rights and certain additional interest provisions that are
applicable to the Old Notes under the Registration Rights Agreement (as
defined). The Exchange Notes will be issued under the indenture dated as of
December 23, 1996 governing the Old Notes (the "Indenture").
 
  The interest rate on the Exchange Notes will be 13% until the Company
achieves and maintains $36 million of Earnings (as defined) for two consecutive
quarters on a trailing twelve-month basis after deducting minority interests
and before interest, taxes, depreciation and amortization calculated in
accordance with generally accepted accounting principles. See "Description of
the Notes--Interest Rate Increase." Interest on the Exchange Notes is payable
semiannually on June 30 and December 31 of each year, commencing June 30, 1997.
Interest on the Exchange Notes will accrue from December 31, 1996. The Exchange
Notes are not redeemable prior to December 31, 1998. The Exchange Notes are
redeemable, in whole or in part, at the option of the Company on or after
December 31, 1998 at the redemption prices set forth herein, plus accrued and
unpaid interest, if any, to the date of redemption.
 
  The Exchange Notes will be senior unsecured obligations of the Company, will
rank senior to all subordinated indebtedness of the Company and will rank pari
passu in right of payment with all existing and future senior indebtedness of
the Company, including the Old Notes and indebtedness under the Credit Facility
(as defined). As of September 30, 1996, after giving pro forma effect to the
issuance of the Old Notes, borrowings under the Credit Facility and application
of the proceeds therefrom, the Company would have had approximately $153.9
million of total indebtedness and $18.8 million secured indebtedness under the
Credit Facility. The Exchange Notes will be unconditionally guaranteed by four
wholly owned subsidiaries of the Company (the "Subsidiary Guarantors").
 
  In the event of a Change of Control (as defined), the Company will be
required to offer to purchase all Exchange Notes then outstanding at a purchase
price equal to 101% of the aggregate principal amount of such Exchange Notes,
plus accrued and unpaid interest, if any, to the date of purchase.
                                                        (Continued on next page)
 
                                  ----------
  HOLDERS OF OLD NOTES SHOULD CAREFULLY CONSIDER THE MATTERS SET FORTH IN "RISK
FACTORS" BEGINNING ON PAGE 7 OF THIS PROSPECTUS PRIOR TO MAKING A DECISION WITH
RESPECT TO THE EXCHANGE OFFER.
 
                                  ----------
 
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
EXCHANGE COMMISSION  OR ANY STATE SECURITIES COMMISSION NOR HAS  THE SECURITIES
AND EXCHANGE COMMISSION  OR ANY  STATE SECURITIES COMMISSION  PASSED UPON THE
ACCURACY OR  ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION  TO THE CONTRARY
IS A CRIMINAL OFFENSE.
 
                                  ----------
                   THE DATE OF THIS PROSPECTUS IS      , 1997
<PAGE>
 
(Continued from previous page)
 
  The Old Notes were originally issued and sold on December 23, 1996 in a
transaction not registered under the Securities Act, in reliance upon the
exemption provided in Section 4(2) of the Securities Act and Rule 144A
promulgated under the Securities Act. Accordingly, the Old Notes may not be
reoffered, resold or otherwise pledged, hypothecated or transferred in the
United States unless so registered or unless an applicable exemption from the
registration requirements of the Securities Act is available. Based upon its
view of interpretations provided to third parties by the Staff (the "Staff")
of the Securities and Exchange Commission (the "Commission"), the Company
believes that the Exchange Notes issued pursuant to the Exchange Offer in
exchange for the Old Notes may be offered for resale, resold and otherwise
transferred by holders thereof (other than any holder that is (i) an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act (an "Affiliate"), (ii) a broker-dealer who acquired Old Notes directly
from the Company or (iii) a broker-dealer who acquired Old Notes as a result
of market-making or other trading activities) without compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided that such Exchange Notes are acquired in the ordinary course of such
holders' business and such holders are not engaged in, and do not intend to
engage in, and have no arrangement or understanding with any person to
participate in, a distribution of such Exchange Notes. Each broker-dealer that
receives Exchange Notes for its own account pursuant to the Exchange Offer
must acknowledge that it will deliver a prospectus in connection with any
resale of Exchange Notes. The Letter of Transmittal that is filed as an
exhibit to the Registration Statement of which this Prospectus is a part (the
"Letter of Transmittal") states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. Broker-dealers who
acquired Old Notes as a result of market-making or other trading activities
may use this Prospectus, as supplemented or amended, in connection with
resales of Exchange Notes. The Company has agreed that, for a period of 180
days after the Exchange Date (as defined), it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. Any
holder who tenders in the Exchange Offer for the purpose of participating in a
distribution of the Exchange Notes and any other holder that cannot rely upon
interpretations of the Staff must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction.
 
  Old Notes initially purchased by qualified institutional buyers and
institutional accredited investors were initially represented by a single,
global Old Note in registered form, registered in the name of a nominee of The
Depository Trust Company ("DTC"), as depository. The Exchange Notes exchanged
for Old Notes represented by the global Old Note will be represented by one or
more global Exchange Notes in registered form, registered in the name of the
nominee of DTC. See "Book-Entry; Delivery and Form." Exchange Notes issued to
persons other than qualified institutional buyers and institutional accredited
investors in exchange for Old Notes held by such investors will be issued only
in certificated, fully registered, definitive form. Except as described
herein, Exchange Notes in definitive certificated form will not be issued in
exchange for the global Old Note or interests therein.
 
  The Old Notes and the Exchange Notes constitute new issues of securities
with no established public trading market. Any Old Notes not tendered and
accepted in the Exchange Offer will remain outstanding. To the extent that Old
Notes are not tendered or are tendered but are not accepted in the Exchange
Offer, a holder's ability to sell such Old Notes could be adversely affected.
Following consummation of the Exchange Offer, the holders of any remaining Old
Notes will continue to be subject to the existing restrictions on transfer
thereof and the Company will have no further obligation to such holders to
provide for the registration under the Securities Act of the Old Notes except
under certain limited circumstances. See "Old Notes Registration Rights;
Additional Interest." No assurance can be given as to the liquidity of the
trading market for the Old Notes or the Exchange Notes. The Old Notes are not
listed on any securities exchange and the Company does not intend to apply for
a listing of the Exchange Notes on a securities exchange.
 
  The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered or accepted for exchange. The Exchange
Offer will expire at 5:00 p.m., New York City time, on    , 1997, unless
extended (the "Expiration Date"). The date of acceptance for exchange of the
Old Notes (the "Exchange Date") will be the first business day following the
Expiration Date, upon surrender of the Old Notes. Old Notes tendered pursuant
to the Exchange Offer may be withdrawn at any time prior to the Expiration
Date; otherwise such tenders are irrevocable.
 
  The Company will not receive any proceeds from the Exchange Offer. The
Company will pay all expenses incident to the Exchange Offer.

                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. The terms "Company" or "ICF Kaiser" in this
Prospectus may refer to ICF Kaiser International, Inc. and/or any of its
consolidated subsidiaries. Effective December 31, 1995, the Company changed its
fiscal year end from February 28 to December 31.
 
                                  THE COMPANY
 
  ICF Kaiser International, Inc., through ICF Kaiser Engineers, Inc. and its
other operating subsidiaries, is one of the nation's largest engineering,
construction, program management and consulting services companies. The
Company's Federal Programs, Engineers and Consulting Groups provide fully
integrated services to domestic and foreign clients in the private and public
sectors of the environment, infrastructure and basic metals and mining industry
markets. For the latest nine-month period ended September 30, 1996, ICF Kaiser
had gross and service revenue of $1,023.4 million and $433.6 million,
respectively. Service revenue is derived by deducting the costs of
subcontracted services and direct project costs from gross revenue and adding
the Company's share of income (loss) of joint ventures and affiliated
companies. As of November 30, 1996, the Company employed 5,176 people located
in more than 80 offices worldwide.
 
  In the environmental market, the Company provides services in connection with
the remediation of hazardous and radioactive waste, waste minimization and
disposal, risk assessment, global warming and acid rain, alternative fuels and
clean up of harbors and waterways. Demand for environmental services is driven
by a number of factors, including: the need to improve the quality of the
environment; federal, state and municipal regulation and enforcement; and
increased liability associated with pollution-related injury and damage. ICF
Kaiser is well-positioned to take advantage of the growing market arising from
the increased awareness internationally of the need for additional and/or
initial environmental regulations, studies and remediation.
 
  ICF Kaiser also provides services to the infrastructure market. This market
is driven by the need to maintain and expand, among other things, ports, roads,
highways, mass transit systems and airports. Increasingly, environmental
concerns, such as wastewater treatment and reducing automotive air pollutant
emissions, are a driving force behind new infrastructure and transportation
initiatives. The Company has capitalized on its specialized technical and
environmental skills to win projects that provide consulting, planning, design
and construction services. Internationally, there is a critical need for
infrastructure projects where population growth of major cities has been and
will continue to be extremely high. The Company currently provides engineering
and construction management services for mass transit and wastewater treatment
facilities in many such major cities worldwide.
 
  ICF Kaiser assists its basic metals and mining industry clients by providing
the engineering and construction skills needed to maintain and retrofit
existing plants and replace aging production capacity with newer, more
efficient and more environmentally responsible facilities. The Company's
engineering and construction skills, as well as its access to process
technologies, have helped establish it as a worldwide leader in serving the
basic metals and mining industries, especially aluminum and steel. ICF Kaiser
is currently expanding its operations internationally, particularly engineering
and construction management services related to alumina production from
bauxite, aluminum smelting and other basic industry facilities.
 
  The Company is currently working on several large, highly visible projects,
including, but not limited to, (i) a five-year contract at the U.S. Department
of Energy's Rocky Flats Environmental Technology site near Golden, Colorado,
(ii) a two-year contract with Nova Hut, an integrated steel maker based in the
Czech Republic, (iii) two four-year Total Environmental Restoration Contracts
("TERC") to perform environmental restoration work at federal installations for
the U.S. Army Corps of Engineers, (iv) a five-year construction management
contract
 
                                       1
<PAGE>
 
for the Boston Harbor wastewater treatment facility and (v) a three-year
contract as the project manager at the light rail transit system in Manila.
 
  ICF Kaiser International, Inc. was incorporated in Delaware 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 1988, the
Company acquired the Kaiser Engineers business which dates from 1914. The
Company's headquarters is located at 9300 Lee Highway, Fairfax, Virginia 22031-
1207, telephone number (703) 934-3600.

                            tendering holders will not be a taxable exchange

                            should not recognize any taxable gain or loss as a
                            result of such exchange.

                            covenant contained in the terms of the Old Notes
                            and the Registration Rights Agreement, and,
                            accordingly, the holders of the Old Notes will have
                            no further registration or other rights under the
                            Registration Rights Agreement, except under certain
                            limited circumstances. See "Old Notes Registration
                            Rights; Additional Interest." Holders of the Old
                            Notes who do not tender their Old Notes in the
                            Exchange Offer will continue to hold such Old Notes
                            and will be entitled to all the rights and
                            limitations applicable thereto under the Indenture.
                            All untendered, and tendered but unaccepted, Old
                            Notes will continue to be subject to the
                            restrictions on transfer provided for in the Old
                            Notes and the Indenture. To the extent that Old
                            Notes are tendered and accepted in the Exchange
                            Offer, the trading market, if any, for the Old
                            Notes not so tendered could be adversely affected.
                            See "Risk Factors--Consequences of Failure to
                            Exchange Old Notes."

                            Company's Earnings are $36 million for one quarter

                 SUMMARY HISTORICAL CONSOLIDATED FINANCIAL DATA
 
  The summary historical consolidated financial data of the Company for the ten
months ended December 31, 1995, and each year in the four-year period ended
February 28, 1995, have been derived from the Company's audited consolidated
financial statements. This information should be read in conjunction with the
Consolidated Financial Statements and the related notes thereto appearing
elsewhere in this Prospectus and "Management's Discussion and Analysis of
Financial Condition and Results of Operations." The summary historical
consolidated financial data of the Company as of September 30, 1995 and 1996
and for the nine-month periods then ended, have been prepared on the same basis
as the consolidated financial statements and, in the opinion of the Company,
include all normal and recurring adjustments (consisting of only normal
recurring adjustments) necessary to present fairly the information set forth
therein. Operating results for the nine months ended September 30, 1996 are not
necessarily indicative of the results that may be expected for the fiscal year
ended December 31, 1996. Certain reclassifications have been made to the prior
period financial statements to conform to the presentation used in the
September 30, 1996 financial statements. The data for the nine months ended
September 30, 1995 and 1996 set forth below are unaudited.

(4) EBITDA represents operating income (loss), excluding unusual items, plus
    depreciation and amortization minus minority interests. Management believes
    that EBITDA is generally accepted as providing useful information regarding
    a company's ability to service and/or incur debt. EBITDA should not be
    considered in isolation or as a substitute for net income, cash flows or
    other consolidated income or cash flow data prepared in accordance with

    profitability or liquidity.
(5) The ratio of earnings to fixed charges is calculated by dividing income
    from continuing operations before fixed charges and income taxes
    ("earnings") by fixed charges. Fixed charges consist of interest expense
    and that portion of rental expense that the Company believes to be
    representative of interest. In the years ended February 29, 1992 and
    February 28, 1994, earnings, as defined, were inadequate to cover fixed
    charges. The deficiencies were $54.3 million and $12.9 million for the
    years ended February 29, 1992 and February 28, 1994, respectively.

                                 RISK FACTORS
 
  In addition to the other information contained in this Prospectus, before
tendering their Old Notes for the Exchange Notes offered hereby, holders of
Old Notes should consider carefully the following factors, which may be
generally applicable to the Old Notes as well as to the Exchange Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
  Holders of Old Notes who do not exchange their Old Notes for Exchange Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes, as set forth in the legend thereon, as a
consequence of the issuance of the Old Notes pursuant to the exemptions from,
or in transactions not subject to, the registration requirements of the
Securities Act and applicable state securities laws. In general, the Old Notes
may not be offered or sold, unless registered under the Securities Act and
applicable state securities laws, or pursuant to an exemption therefrom.
Except under certain limited circumstances, the Company does not intend to
register the Old Notes under the Securities Act. In addition, any holder of
Old Notes who tenders in the Exchange Offer for the purpose of participating
in a distribution of the Exchange Notes may be deemed to have received
restricted securities and, if so, will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. To the extent Old Notes are tendered
and accepted in the Exchange Offer, the trading market, if any, for the Old
Notes not so tendered could be adversely affected. See "The Exchange Offer"
and "Old Notes Registration Rights; Additional Interest."
 
COMPANY IS HIGHLY LEVERAGED
 
  On a pro forma basis, at September 30, 1996, assuming the issuance of the
Old Notes, borrowings under the Credit Facility and application of the net
proceeds therefrom, the Company would have had total indebtedness of $153.9
million, representing 82.4% of total capitalization. Effective March 8, 1996,
the Company agreed to increase the interest rate on the Company's 12% Senior
Subordinated Notes due 2003 (the "Existing Notes") by one percent until the
Company achieves and maintains a specified level of earnings as defined in the
Fourth Supplemental Indenture to the Indenture dated as of January 11, 1994
(as such Indenture has been and may be amended, restated, supplemented or
otherwise modified from time to time, the "Existing Indenture") governing the
Existing Notes. The Indenture governing the Notes contains an identical
increased interest rate provision.
 
  The degree to which the Company is leveraged could have important
consequences to holders of the Notes, including, but not limited to, the
following: (i) the Company's ability to obtain additional financing in the
future for working capital, capital expenditures, acquisitions, general
corporate or other purposes may be limited; (ii) a substantial portion of the
Company's cash flow from operations will be dedicated to the payment of the
principal of, and interest on, its debt; (iii) the agreements governing the
Company's long-term debt contain certain restrictive financial and operating
covenants which could limit the Company's ability to expand; (iv) the
Company's substantial leverage may make it more vulnerable to economic
downturns and reduce its flexibility in responding to changing business and
economic conditions; and (v) the level of the Company's leverage may make it
more difficult for the Company to obtain performance and similar bonds. The
ability of the Company to pay interest and principal on the Notes and to
satisfy its other debt obligations will be dependent on the future operating
performance of the Company, which could be affected by changes in economic
conditions and other factors, including factors beyond the control of the
Company. A failure to comply with the covenants and other provisions of its
debt instruments could result in events of default under such instruments,
which could permit acceleration of the debt under such instruments and in some
cases acceleration of debt under other instruments that contain cross-default
or cross-acceleration provisions.
 
  If the Company is unable to generate sufficient cash flow to meet its debt
obligations, the Company may be required to renegotiate the terms of the
instruments relating to its long-term debt or to refinance all or a portion of
its long-term debt. However, there can be no assurance that the Company will
be able to successfully renegotiate such terms or refinance its indebtedness,
or, if the Company were able to do so, that the terms
 
                                       7
<PAGE>
 
available would be favorable to the Company. In the event that the Company
were unable to refinance its indebtedness or obtain new financing under these
circumstances, the Company would have to consider various other options such
as the sale of certain assets to meet its required debt service, negotiation
with its lenders to restructure applicable indebtedness or other options
available to it under law. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
HISTORY OF NET LOSSES
 
  As shown in the following table, for three of the past five fiscal years,
the Company has had net losses; fiscal 1992 reflects an after-tax charge of
$52.4 million associated with the disposal and restructuring of certain
businesses. The Company's cumulative deficit at September 30, 1996 was $30.8
million.

</TABLE>
 
RECENT AND ANTICIPATED RESULTS
 
  For the three months ended September 30, 1996, the Company's operating
income decreased $2.8 million from the corresponding period in 1995, primarily
due to a decrease in operating income from engineering and construction
operations. The Company's service revenue and operating results for the fourth
quarter will be significantly lower than the third quarter. For the nine
months ended September 30, 1996, the Company's Federal Programs Group had
significant increases in costs associated with marketing activities in pursuit
of large-scale projects, including approximately $2.1 million in 1996
associated with the Company's unsuccessful recompete bid on the U.S.
Department of Energy's ("DOE") proposal at its Hanford site ("Hanford") and
significant costs associated with other DOE proposals. In August 1996, the
Company was informed that it was unsuccessful in its bid for the DOE's new
management and integration contract at Hanford. The Company's existing
contract at Hanford, the operating income from which has been significant to
the Company's results, was set to expire in March 1997, and effectively was
terminated by DOE on October 1, 1996. Management believes the impact on
earnings due to the closeout of the Hanford contract will be material in the
fourth quarter of 1996. Management also believes the impact on earnings due to
the closeout of the Hanford contract will be material in future periods,
unless replaced with new contracts or offset by savings from the Company's on-
going cost reduction program. There can be no assurance, however, that the
Company will be able to enter into new contracts or achieve cost savings that
will, in the aggregate, totally offset the effect of the loss of the Hanford
contract. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
  In March 1996, the Company and Nova Hut, an integrated steel maker based in
the Ostrava region of the Czech Republic, signed a two-year $102 million
contract to provide engineering and construction services for the initial
phase of a mini-mill project. The Company is currently negotiating a contract
with Nova Hut for the next phase of the mini-mill project and expects to
complete negotiations in the first quarter of 1997. If negotiations are
successful, anticipated earnings associated with this contract for the next
phase of work are expected to be material to the Company's operating results.
There can be no assurance, however, that such negotiations will be completed.
 
  The Company has sold (the "Disposition") its interest in entities owning and
operating a pulverized coal injection facility in Indiana ("PCI"). Although
the sale will result in a gain in the fourth quarter of 1996, the negative
effect of the sale in future periods on earnings and cash flows will be
significant. See "Unaudited Pro Forma Consolidated Financial Statements."

LIMITED ABILITY TO INCUR ADDITIONAL DEBT
 
  Excluding borrowings under the Credit Facility, the Existing Indenture and
the Indenture (together, the "Indentures") limit the Company's ability to
incur additional Indebtedness (as defined). The amount of available additional
indebtedness may be insufficient for working capital needs, potential
acquisitions, significant capital expenditures, repayment of debt or other
purposes. See "Description of the Notes--Certain Covenants--Limitations on
Additional Indebtedness" and "Description of the Credit Facility."
 
COMPANY DEPENDENT ON FEDERAL GOVERNMENT CONTRACTS
 
  A substantial portion of ICF Kaiser's revenues are derived from services
performed directly or indirectly under contracts with various agencies and
departments of the Federal government. During the ten months ended December
31, 1995, approximately 78% of the Company's consolidated gross revenue was
derived from contracts with the U.S. Government. During the ten months ended
December 31, 1995, the DOE accounted for approximately 68% of consolidated
gross revenue; the U.S. Department of Defense ("DOD"), the U.S. Environmental
Protection Agency ("EPA") and other Federal agencies collectively accounted
for approximately 10% of the Company's consolidated gross revenue.
 
  The Company's existing contract at Hanford effectively was terminated by DOE
on October 1, 1996. As a result, and based on the Company's current assessment
of the closeout of the Hanford contract, management believes the impact on
earnings will be material in the fourth quarter of 1996, as well as in future
periods, unless replaced with new contracts and/or cost reductions. In
response to the reduction and eventual elimination of the Hanford contract, in
August 1996 the Company initiated a significant operational efficiency and
cost savings program, together with management changes, with the objective of
minimizing the long-term impact associated with the termination of the Hanford
contract. See "--Recent and Anticipated Results."
 
  Contracts made with the U.S. Government generally are subject to annual
approval of funding. Limitations imposed on spending by Federal government
agencies, which might result from efforts to reduce the Federal deficit or for
other reasons, may limit the continued funding of the Company's existing
Federal government contracts and may limit the ability of the Company to
obtain additional contracts or task orders under existing contracts. These
limitations, if significant, could have a material adverse effect on the
Company.
 
  The Company has a substantial number of cost-reimbursement contracts with
the U.S. government, the costs of which are subject to audit by the U.S.
government. As a result of pending audits relating to fiscal years 1986
forward, the government has asserted, among other things, that certain costs
claimed as reimbursable under government contracts either were not allowable
or not allocated in accordance with federal procurement regulations. The
Company is actively working with the government to resolve these issues. The
Company has provided for the potential effect of disallowed costs for the
periods currently under audit and for periods not yet audited, although the
amounts at issue have not been quantified by the government or the Company.
This provision will be reviewed periodically as discussions with the
government progress. Based on the information currently available, management
believes the potential effects of these pending audits will not have a
material adverse effect on the Company's financial position, results of
operations or cash flows.
 
  All Federal contracts may be terminated by the U.S. Government at any time,
with or without cause. There can be no assurance that existing or future
Federal government contracts would not be terminated or that the government
will continue to use the Company's services at levels comparable to current
use.
 
RISK ASSOCIATED WITH COMPANY'S PLEDGE OF ASSETS
 
  The Company and most of its subsidiaries have granted a security interest in
substantially all of their accounts receivable and certain other assets to
secure all debt incurred pursuant to the Credit Facility. The Company would
not be able to incur additional debt (including additional debt permitted by
the Indentures) if
 
                                       9
<PAGE>
 
the Company were required to pledge assets in connection with the incurrence
of such additional debt. In the event of bankruptcy or liquidation of the
Company there can be no assurance that sufficient assets would be available
for payment of the Notes.
 
LIMITED ABILITY TO MAKE ACQUISITIONS AND OTHER INVESTMENTS
 
  The Credit Facility limits the Company's ability to make acquisitions and
other investments, and the Indentures limit the Company's ability to make
restricted payments, including certain payments in connection with investments
and acquisitions. Limitations in the Existing Indenture are based in part on
the Company's Consolidated Net Income (as defined) during the period since
August 31, 1993; the losses incurred by the Company during fiscal 1994 and
1995 have the effect of making this limitation very restrictive.
 
  The indebtedness, investment, acquisitions and restricted payments
limitations in the Credit Facility and the Indentures discussed above mean
that during the next several years it likely will be necessary for the Company
to issue additional equity securities to fund any significant acquisitions and
to invest significant amounts in joint ventures. These limitations may make it
more difficult for the Company to compete effectively in its markets.
 
FRAUDULENT CONVEYANCE LAWS
 
  The incurrence by the Company of indebtedness such as the Notes may be
subject to review under relevant state and federal fraudulent conveyance laws
if a bankruptcy case or lawsuit is commenced on behalf of unpaid creditors of
the Company. Under these statutes, if a court were to find that (i) the Notes
were incurred with the intent of hindering, delaying or defrauding creditors
or that the Company received less than a reasonably equivalent value or fair
consideration for the Notes and (ii) at the time the Notes were issued, the
Company was insolvent, was rendered insolvent by the issuance of the Notes,
was engaged in a business or transaction for which the assets remaining with
the Company constituted unreasonably small capital, or intended to incur, or
believed that it would incur, debts beyond its ability to pay such debts as
they matured, such court could void the Company's obligations under the Notes,
or subordinate the Notes to all other indebtedness of the Company. In that
event, there would be no assurance that any repayment on the Notes would ever
by recovered by holders of the Notes. The measure of insolvency for purposes
of the foregoing would vary depending upon the law of the jurisdiction which
is being applied. Generally, however, the Company would be considered to have
been insolvent at the time the Notes were issued if the sum of its debts was
then greater than all of its property at a fair valuation, or if the then fair
saleable value of its assets was less than the amount that was then required
to pay its probable liability on its existing debts as they become absolute
and matured. There can be no assurance as to what standard a court would apply
in order to determine whether the Company was "insolvent" as of the date the
Notes were issued, or that, regardless of the method of valuation, a court
would not determine that the Company was insolvent on that date. Nor can there
be any assurance that a court would not determine, regardless of whether the
Company was insolvent on the date the Notes were issued, that the payments
constituted fraudulent transfers on another of the grounds listed above.
 
LIMITATIONS ON CHANGE OF CONTROL
 
  In the event of a Change of Control, the Company would be required, subject
to certain conditions, to offer to purchase all outstanding Existing Notes and
Notes at a price equal to 101% of the principal amount thereof, plus accrued
and unpaid interest, if any, thereon to the date of purchase. As of September
30, 1996, the Company did not have sufficient funds available to purchase all
of the Existing Notes and Notes were they to be tendered in response to an
offer made as a result of such a Change of Control. There can be no assurance
that, at the time of a Change of Control, the Company will have sufficient
cash to repay all amounts due under the Existing Notes and Notes. The terms of
the Credit Facility prohibit the optional payment or prepayment or any
redemption of the Existing Notes and Notes. If, following a Change of Control,
the Company has insufficient funds to purchase all the Existing Notes and
Notes tendered pursuant to such an offer, an event of default in respect of
such Notes would occur. The Change of Control provisions of the Indentures may
have the effect of discouraging attempts by a person or group to take control
of the Company. See "Description of the Notes--Change of Control."
 
                                      10
<PAGE>
 
  The Company's Restated Certificate of Incorporation, By-laws, Shareholder
Rights Plan and certain other agreements contain provisions that could have
the effect of delaying or preventing a change of control of the Company or
affect the Company's ability to engage in certain extraordinary transactions.
 
COMPANY DEPENDENT ON GOVERNMENTAL ENVIRONMENTAL REGULATION CONTINUING
 
  A substantial portion of the Company's business has been generated either
directly or indirectly as a result of Federal and state laws, regulations and
programs related to environmental issues. Accordingly, a reduction in the
number or scope of these laws and regulations, or changes in government
policies regarding the funding, implementation or enforcement of such laws,
regulations and programs, could have a material adverse effect on the
Company's business. In addition, any significant effort by the DOE to reduce
the role of private contractors in environmental projects could have a
material adverse effect on the Company.
 
POTENTIAL ENVIRONMENTAL LIABILITY FOR COMPANY'S WORK
 
  The assessment, analysis, remediation, handling, management, and disposal of
hazardous substances necessarily involve significant risks, including the
possibility of damages or personal injuries caused by the escape of hazardous
materials into the environment, and the possibility of fines, penalties or
other regulatory action. These risks include potentially large civil and
criminal liabilities for violations of environmental laws and regulations, and
liabilities to customers and to third parties for damages arising from
performing services for clients.
 
 Potential Liabilities Arising Out of Environmental Laws and Regulations
 
  All facets of the Company's business are conducted in the context of a
rapidly developing and changing statutory and regulatory framework. The
Company's operations and services are affected by and subject to regulation by
a number of Federal agencies, including the EPA and the Occupational Safety
and Health Administration, as well as applicable state and local regulatory
agencies. The Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA") addresses cleanup of sites at which there has been a release or
threatened release of hazardous substances into the environment. Increasingly,
there are efforts to expand the reach of CERCLA to make environmental
contractors responsible for cleanup costs by claiming that environmental
contractors are owners or operators of hazardous waste facilities or that they
arranged for treatment, transportation, or disposal of hazardous substances.
Several recent court decisions have accepted these claims. Should the Company
be held responsible under CERCLA for damages caused while performing services
or otherwise, it may be forced to bear such liability by itself,
notwithstanding the potential availability of contribution or indemnity from
other parties. The Resource Conservation and Recovery Act ("RCRA") governs
hazardous waste generation, treatment, transportation, storage and disposal.
RCRA, or EPA-approved state programs at least as stringent, govern waste
handling activities involving wastes classified as "hazardous." Substantial
fees and penalties may be imposed under RCRA and similar state statutes for
any violation of such statutes and the regulations thereunder.
 
 Potential Liabilities Involving Clients and Third Parties
 
  In performing services for its clients, the Company 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.
 
  Environmental contractors, in connection with work performed for clients,
potentially face liabilities to third parties from various claims, including
claims for property damage or personal injury stemming from a release of
hazardous substances or otherwise. Claims for damage to third parties could
arise in a number of ways, including through a sudden and accidental release
or discharge of contaminants or pollutants during the performance of services;
through the inability, despite reasonable care, of a remedial plan to contain
or correct an ongoing
 
                                      11
<PAGE>
 
seepage or release of pollutants; through the inadvertent exacerbation of an
existing contamination problem; or through reliance on reports or
recommendations prepared by the Company. Personal injury claims could arise
contemporaneously with performance of the work or long after completion of the
project as a result of alleged exposure to toxic or hazardous substances. In
addition, increasing numbers of claimants assert that companies performing
environmental remediation should be adjudged strictly liable, i.e., liable for
damages even though its services were performed using reasonable care, on the
grounds that such services involved "abnormally dangerous activities."
 
  Clients frequently attempt to shift various of the liabilities arising out
of remediation of their own environmental problems to contractors through
contractual indemnities. Such provisions seek to require the Company to assume
liabilities for damage or personal injury to third parties and property and
for environmental fines and penalties including liabilities arising as a
result of breaches by the Company of specified standards of care.
 
  For EPA contracts involving field services in connection with response
actions under Superfund, a program established under CERCLA to clean up
hazardous waste sites and provide for penalties and punitive damages for
noncompliance with EPA orders, the Company is eligible for indemnification
under Section 119 of CERCLA, for pollution and environmental damage liability
resulting from release or threatened release of hazardous substances.
Recently, EPA has constricted significantly the circumstances under which it
will indemnify its contractors against liabilities incurred in connection with
CERCLA projects. There are other proposals both in Congress and at the
regulatory agencies to further restrict indemnification of contractors from
third-party claims.
 
  Kaiser-Hill Company, LLC ("Kaiser Hill") (a limited liability company owned
equally by the Company and CH2M Hill Companies, Ltd.) signed a five-year
Performance Based Integrating Management contract in 1995 to perform work at
the DOE's Rocky Flats Environmental Technology Site near Golden, Colorado. The
terms of that contract govern 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 shall be responsible, but only for the
incremental liability, expense or remediation caused by Kaiser-Hill. The
contract further provides that Kaiser-Hill will not be reimbursed for
liabilities and expenses to third parties 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.
 
MARKET FOR COMPANY'S SERVICES HIGHLY COMPETITIVE
 
  The market for the Company's services is highly competitive. The Company and
its subsidiaries compete with many other environmental consulting, engineering
and construction firms ranging from small firms to large multinational firms
having substantially greater financial, management, and marketing resources
than the Company. Other competitive factors include quality of services,
technical qualifications, reputation, geographic presence, price, and the
availability of key professional personnel. See "Business--Competition and
Contract Award Process."
 
RISKS ASSOCIATED WITH COMPANY'S ABILITY TO ATTRACT AND RETAIN PROFESSIONAL
PERSONNEL
 
  The Company's ability to retain and expand its staff of qualified
professionals is an important factor in determining the Company's future
success. The market for these professionals, especially environmental
professionals, is competitive. There can be no assurance that the Company will
continue to be successful in its efforts to attract and retain such
professionals.

FLUCTUATIONS IN QUARTERLY FINANCIAL RESULTS
 
  The Company's quarterly financial results may be affected by a number of
factors, including the commencement, completion or termination of major
projects. Accordingly, results for any one quarter are not necessarily
indicative of results for any other quarter or for the year.
 
ABSENCE OF PUBLIC MARKET FOR THE EXCHANGE NOTES
 
  The Exchange Notes are being offered to the holders of the Old Notes. The
Old Notes were offered and sold in December 1996 to a small number of
institutional and accredited investors and are eligible for trading in the
Private Offerings, Resale and Trading through Automated Linkages ("PORTAL")
Market.
 
  The Company does not intend to apply for a listing of the Exchange Notes on
a securities exchange. There is currently no established market for the
Exchange Notes and there can be no assurance as to the liquidity of markets
that may develop for the Exchange Notes, the ability of the holders of the
Exchange Notes to sell their Exchange Notes or the price at which such holders
would be able to sell their Exchange Notes. If such markets were to exist, the
Exchange Notes could trade at prices that may be lower than the initial market
values thereof, depending on many factors, including prevailing interest
rates, the markets for similar securities, and the financial performance of
the Company. The Initial Purchaser has made a market for the Old Notes.
Although there is currently no market for the Exchange Notes, the Initial
Purchaser has advised the Company that it currently intends to make a market
in the Exchange Notes. However, the Initial Purchaser is not obligated to do
so, and any such market making with respect to the Old Notes or the Exchange
Notes may be discontinued at any time without notice. In addition, such
market-making activities will be subject to the limits imposed by the
Securities Act and the Exchange Act and may be limited during the Exchange
Offer or the pendency of an applicable Shelf Registration Statement (as
defined).
 
  The liquidity of, and trading market for, the Exchange Notes also may be
adversely affected by general declines in the market for similar securities.
Such a decline may adversely affect such liquidity and trading markets
independent of the financial performance of, and prospects for, the Company.
 
ORIGINAL ISSUE DISCOUNT
 
  The Old Notes were issued with original issue discount. Consequently,
holders of Exchange Notes will have income for tax purposes arising from such
original issue discount prior to the actual receipt of cash in respect of such
income. See "Certain Federal Income Tax Considerations" for a more detailed
discussion of the federal income tax consequences to the holders of the
Exchange Notes of the exchange of Old Notes for Exchange Notes and the
ownership and disposition of the Exchange Notes.
 
  If a bankruptcy case is commenced by or against the Company under the United
States Bankruptcy Code (the "Bankruptcy Code"), the claim of a holder of any
of the Notes with respect to the principal amount thereof may be limited to an
amount equal to the sum of (i) the initial offering price allocable to the Old
Notes and (ii) that portion of the original issue discount that is not deemed
to constitute "unmatured interest" for purposes of the Bankruptcy Code. Any
original issue discount that was not amortized as of any such bankruptcy
filing would constitute "unmatured interest."
 
                                USE OF PROCEEDS
 
  There will be no cash proceeds to the Company resulting from the Exchange
Offer.
 
  The Company used the net proceeds received from the sale of the Old Notes to
repurchase a portion of the Company's Series 2D Senior Preferred Stock having
an aggregate liquidation preference of $20.0 million. The balance of the
Series 2D Senior Preferred Stock was repurchased using borrowings under the
Credit Facility. See "Unaudited Pro Forma Consolidated Financial Statements."

                              THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
  The sole purpose of the Exchange Offer is to fulfill the obligations of the
Company under the Registration Rights Agreement with respect to the
registration of the Old Notes.
 
  The Old Notes originally were issued and sold on December 23, 1996 (the
"Issue Date"). Such sales were not registered under the Securities Act in
reliance upon the exemption provided by Section 4(2) of the Securities Act and
Rule 144A promulgated under the Securities Act. In connection with the sale of
the Old Notes, the Company agreed to file with the Commission the Registration
Statement, pursuant to which the Exchange Notes, consisting of another series
of senior notes of the Company covered by such Registration Statement and
containing substantially identical terms to the Old Notes, except as set forth
in this Prospectus, would be offered in exchange for Old Notes tendered at the
option of the holders thereof. If (i) because of any change in law or in
currently prevailing interpretations of the Staff of the Commission the
Company is not permitted to effect the Exchange Offer, (ii) the Exchange Offer
is not consummated within 180 days of the Issue Date, (iii) in certain
circumstances, after the consummation of the Exchange Offer, the Initial
Purchaser continues to hold Exchange Notes and so requests, (iv) the holders
of not less than a majority in aggregate principal amount of the Old Notes
determine that the interests of the holders would be materially adversely
affected by consummation of the Exchange Offer or (v) in the case of any
holder of Old Notes that participates in the Exchange Offer, such holder does
not receive Exchange Notes on the date of the exchange that may be sold
without restriction under state and federal securities laws (other than due
solely to the status of such holder as an Affiliate of the Company), then the
Company will file with the Commission a registration statement (the "Shelf
Registration Statement") to cover resales of the Old Notes by the holders
thereof who satisfy certain conditions relating to the provision of
information in connection with the Shelf Registration Statement. In the event
that (i) the Company fails to file the Registration Statement, (ii) the
Registration Statement or, if applicable, the Shelf Registration Statement, is
not declared effective by the Commission or (iii) the Exchange Offer is not
consummated or the Shelf Registration Statement ceases to be effective, in
each case within specified time periods, the interest rate borne by the Old
Notes will be increased. See "Old Notes Registration Rights; Additional
Interest."
 
TERMS OF THE EXCHANGE
 
  The Company hereby offers to exchange, upon the terms and subject to the
conditions set forth herein and in the Letter of Transmittal accompanying the
Registration Statement of which this Prospectus is a part, $1,000 in principal
amount of Exchange Notes for each $1,000 in principal amount of Old Notes. The
terms of the Exchange Notes are substantially identical to the terms of the
Old Notes for which they may be exchanged pursuant to this Exchange Offer,
except that the Exchange Notes generally will be freely transferable by
holders thereof, and the holders of the Exchange Notes (as well as remaining
holders of any Old Notes) are not entitled to certain registration rights and
certain additional interest provisions that are applicable to the Old Notes
under the Registration Rights Agreement. The Exchange Notes will evidence the
same debt as the Old Notes and will be entitled to the benefits of the
Indenture. See "Description of the Notes."
 
  The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered or accepted for exchange.
 
  Based on its view of interpretations set forth in no-action letters issued
by the Staff to third parties, the Company believes that Exchange Notes issued
pursuant to the Exchange Offer in exchange for the Old Notes may be offered
for resale, resold and otherwise transferred by holders thereof (other than
any holder that is (i) an Affiliate of the Company, (ii) a broker-dealer who
acquired Old Notes directly from the Company or (iii) a broker-dealer who
acquired Old Notes as a result of market making or other trading activities)
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided that such Exchange Notes are acquired in the
ordinary course of such holders' business, and such holders are not engaged
in, and do not intend to engage in, and have no arrangement or understanding
with any person to participate in, a
 
                                      14
<PAGE>
 
distribution of such Exchange Notes. Any broker-dealer that resells Exchange
Notes that were received by it for its own account pursuant to the Exchange
Offer and any broker or dealer that participates in a distribution of such
Exchange Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of Exchange Notes and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. Broker-dealers who
acquired Old Notes as a result of market-making or other trading activities
may use this Prospectus, as supplemented or amended, in connection with
resales of the Exchange Notes. The Company has agreed that, for a period of
180 days after the Exchange Date, it will make this Prospectus available to
any broker-dealer for use in connection with any such resale. Any holder who
tenders in the Exchange Offer for the purpose of participating in a
distribution of the Exchange Notes or any other holder that cannot rely upon
such interpretations must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.
 
  Tendering holders of Old Notes will not be required to pay brokerage
commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the exchange of the Old Notes
pursuant to the Exchange Offer.
 
  The Exchange Notes will bear interest from December 31, 1996. Holders of Old
Notes whose Old Notes are accepted for exchange will be deemed to have waived
the right to receive any payment in respect of interest on the Old Notes
accrued from December 31, 1996 to the date of the issuance of the Exchange
Notes. Interest on the Exchange Notes is payable semiannually in arrears on
June 30 and December 31 of each year, commencing June 30, 1997, accruing from
December 31, 1996 at a rate of 12% per annum, subject to a temporary interest
rate increase to 13% until the occurrence of certain events. See "Description
of the Notes--Interest Rate Increase."
 
EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS
 
  The Exchange Offer expires on the Expiration Date. The term "Expiration
Date" means 5:00 p.m., New York City time, on     , 1997 unless the Company in
its sole discretion extends the period during which the Exchange Offer is
open, in which event the term "Expiration Date" means the latest time and date
on which the Exchange Offer, as so extended by the Company, expires. The
Company reserves the right to extend the Exchange Offer at any time and from
time to time prior to the Expiration Date by giving written notice to Bankers
Trust Company (the "Exchange Agent") and by timely public announcement
communicated by no later than 5:00 p.m. on the next business day following the
Expiration Date, unless otherwise required by applicable law or regulation, by
making a release to the Dow Jones News Service. During any extension of the
Exchange Offer, all Old Notes previously tendered pursuant to the Exchange
Offer will remain subject to the Exchange Offer.
 
  The initial Exchange Date will be the first business day following the
Expiration Date. The Company expressly reserves the right to (i) terminate the
Exchange Offer and not accept for exchange any Old Notes for any reason,
including if any of the events set forth below under "Conditions to the
Exchange Offer" shall have occurred and shall not have been waived by the
Company and (ii) amend the terms of the Exchange Offer in any manner, whether
before or after any tender of the Old Notes. If any such termination or
amendment occurs, the Company will notify the Exchange Agent in writing and
will either issue a press release or give written notice to the holders of the
Old Notes as promptly as practicable. Unless the Company terminates the
Exchange Offer prior to 5:00 p.m., New York City time, on the Expiration Date,
the Company will exchange the Exchange Notes for Old Notes on the Exchange
Date.
 
  This Prospectus and the related Letter of Transmittal and other relevant
materials will be mailed by the Company to record holders of Old Notes and
will be furnished to brokers, banks and similar persons whose names, or the
names of whose nominees, appear on the lists of holders for subsequent
transmittal to beneficial owners of Old Notes.
 
 
                                      15

HOW TO TENDER
 
  The tender to the Company of Old Notes by a holder thereof pursuant to one
of the procedures set forth below will constitute an agreement between such
holder and the Company in accordance with the terms and subject to the
conditions set forth herein and in the Letter of Transmittal.
 
 General Procedures
 
  A holder of an Old Note may tender the same by (i) properly completing and
signing the Letter of Transmittal or a facsimile thereof (all references in
this Prospectus to the Letter of Transmittal shall be deemed to include a
facsimile thereof) and delivering the same, together with the certificate or
certificates representing the Old Notes being tendered and any required
signature guarantees (or a timely confirmation of a book-entry transfer (a
"Book-Entry Confirmation") pursuant to the procedure described below), to the
Exchange Agent at its address set forth on the back cover of this Prospectus
on or prior to the Expiration Date or (ii) complying with the guaranteed
delivery procedures described below.
 
  If tendered Old Notes are registered in the name of the signer of the Letter
of Transmittal and the Exchange Notes to be issued in exchange therefor are to
be issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder, the signature of such signer need not be guaranteed. In any
other case, the tendered Old Notes must be endorsed or accompanied by written
instruments of transfer in form satisfactory to the Company and duly executed
by the registered holder and the signature on the endorsement or instrument of
transfer must be guaranteed by a bank, broker, dealer, credit union, savings
association, clearing agency or other institution (each an "Eligible
Institution") that is a member of a recognized signature guarantee medallion
program within the meaning of Rule 17Ad-15 under the Exchange Act. If the
Exchange Notes and/or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note
register for the Old Notes, the signature on the Letter of Transmittal must be
guaranteed by an Eligible Institution.
 
  Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender Old Notes should contact such holder promptly and instruct such holder
to tender Old Notes on such beneficial owner's behalf. If such beneficial
owner wishes to tender such Old Notes itself, such beneficial owner must,
prior to completing and executing the Letter of Transmittal and delivering
such Old Notes, either make appropriate arrangements to register ownership of
the Old Notes in such beneficial owner's name or follow the procedures
described in the immediately preceding paragraph. The transfer of record
ownership may take considerable time.
 
 Book-Entry Transfer
 
  The Exchange Agent will make a request to establish an account with respect
to the Old Notes at DTC (the "Book-Entry Transfer Facility") for purposes of
the Exchange Offer within two business days after receipt of this Prospectus,
and any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Notes by causing the
Book-Entry Transfer Facility to transfer such Old Notes into the Exchange
Agent's account at the Book-Entry Transfer Facility in accordance with the
Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Old Notes may be effected through book-entry transfer at the Book-
Entry Transfer Facility, the Letter of Transmittal, with any required
signature guarantees and any other required documents, must, in any case, be
transmitted to and received by the Exchange Agent at the address specified on
the back cover of this Prospectus on or prior to the Expiration Date or the
guaranteed delivery procedures described below must be complied with.
 
  THE METHOD OF DELIVERY OF OLD NOTES AND ALL OTHER DOCUMENTS IS AT THE
ELECTION AND RISK OF THE HOLDER. IF SENT BY MAIL, IT IS RECOMMENDED THAT
REGISTERED MAIL, RETURN RECEIPT REQUESTED, BE USED, PROPER INSURANCE BE
OBTAINED, AND THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE EXPIRATION
DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT ON OR BEFORE THE EXPIRATION
DATE.
 
                                      16
<PAGE>
 
  Unless an exemption applies under the applicable law and regulations
concerning "backup withholding" of federal income tax, the Exchange Agent will
be required to withhold, and will withhold, 31% of the gross proceeds
otherwise payable to a holder pursuant to the Exchange Offer if the holder
does not provide its taxpayer identification number (social security number or
employer identification number, as applicable) and certify that such number is
correct. Each tendering holder should complete and sign the main signature
form and the Substitute Form W-9 included as part of the Letter of
Transmittal, so as to provide the information and certification necessary to
avoid backup withholding, unless an applicable exemption exists and is proved
in a manner satisfactory to the Company and the Exchange Agent.
 
 Guaranteed Delivery Procedures
 
  If a holder desires to accept the Exchange Offer and time will not permit a
Letter of Transmittal or Old Notes to reach the Exchange Agent before the
Expiration Date, a tender may be effected if the Exchange Agent has received
at its office listed on the Letter of Transmittal on or prior to the
Expiration Date a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
principal amount of the Old Notes being tendered, the names in which the Old
Notes are registered and, if possible, the certificate numbers of the Old
Notes to be tendered, and stating that the tender is being made thereby and
guaranteeing that within five New York Stock Exchange trading days after the
date of execution of such letter, telegram or facsimile transmission by the
Eligible Institution, the Old Notes, in proper form for transfer, will be
delivered by such Eligible Institution together with a properly completed and
duly executed Letter of Transmittal (and any other required documents). Unless
Old Notes being tendered by the above-described method (or a timely Book-Entry
Confirmation) are deposited with the Exchange Agent within the time period set
forth above (accompanied or preceded by a properly completed Letter of
Transmittal and any other required documents), the Company may, at its option,
reject the tender. Copies of a Notice of Guaranteed Delivery which may be used
by Eligible Institutions for the purposes described in this paragraph are
available from the Exchange Agent.
 
  A tender will be deemed to have been received as of the date when the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a timely Book-Entry Confirmation) is received
by the Exchange Agent. Issuances of Exchange Notes in exchange for Old Notes
tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram or
facsimile transmission to similar effect (as provided above) by an Eligible
Institution will be made only against deposit of the Letter of Transmittal
(and any other required documents) and the tendered Old Notes (or a timely
Book-Entry Confirmation).
 
  All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptances for exchange of which may, in the opinion of counsel
to the Company, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or
irregularities in tenders of any particular holder whether or not similar
defects or irregularities are waived in the case of other holders. Neither the
Company, the Exchange Agent nor any other person will be under any duty to
give notification of any defects or irregularities in tenders or shall incur
any liability for failure to give any such notification. The Company's
interpretation of the terms and conditions of the Exchange Offer (including
the Letter of Transmittal and the instructions thereto) will be final and
binding.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
  The Letter of Transmittal contains, among other things, the following terms
and conditions, which are part of the Exchange Offer.
 
  The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and it revocably
constitutes and appoints the Exchange Agent as the Transferor's agent and
attorney-in-fact to cause the Old Notes to be assigned, transferred and
exchanged. The Transferor represents
 
                                      17
<PAGE>
 
and warrants that it has full power and authority to tender, exchange, assign
and transfer the Old Notes and to acquire Exchange Notes issuable upon the
exchange of such tendered Old Notes, and that, when the same are accepted for
exchange, the Company will acquire good and unencumbered title to the tendered
Old Notes, free and clear of all liens, restrictions, charges and encumbrances
and not subject to any adverse claim. The Transferor also warrants that it
will, upon request, execute and deliver any additional documents deemed by the
Company to be necessary or desirable to complete the exchange, assignment and
transfer of tendered Old Notes. The Transferor further agrees that acceptance
of any tendered Old Notes by the Company and the issuance of Exchange Notes in
exchange therefor shall constitute performance in full by the Company of its
obligations under the Registration Rights Agreement and that the Company shall
have no further obligations or liabilities thereunder (except in certain
limited circumstances). All authority conferred by the Transferor will survive
the death or incapacity of the Transferor and every obligation of the
Transferor shall be binding upon the heirs, legal representatives, successors,
assigns, executors and administrators of such Transferor.
 
  By tendering Old Notes and executing the Letter of Transmittal, the
Transferor certifies that (a) it is not an Affiliate of the Company, that it
is not a broker-dealer that owns Old Notes acquired directly from the Company
or an Affiliate of the Company, that it is acquiring the Exchange Notes
offered hereby in the ordinary course of such Transferor's business and that
such Transferor has no arrangement with any person to participate in the
distribution of such Exchange Notes, (b) that it is an Affiliate of the
Company or of the Initial Purchaser of the Old Notes and that it will comply
with the registration and prospectus delivery requirements of the Securities
Act to the extent applicable to it, or (c) that it is a Participating Broker-
Dealer (as defined in the Registration Rights Agreement) and that it will
deliver a prospectus in connection with any resale of such Exchange Notes. By
tendering Old Notes and executing the Letter of Transmittal, the Transferor
further certifies that it is not engaged in and does not intend to engage in a
distribution of the Exchange Notes.
 
WITHDRAWAL RIGHTS
 
  Old Notes tendered pursuant to the Exchange Offer may be withdrawn at any
time prior to the Expiration Date.
 
  For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Exchange Agent at its address set
forth on the back cover of this Prospectus prior to the Expiration Date. Any
such notice of withdrawal must specify the person named in the Letter of
Transmittal as having tendered Old Notes to be withdrawn, the certificate
numbers of Old Notes to be withdrawn, the principal amount of Old Notes to be
withdrawn, a statement that such holder is withdrawing its election to have
such Old Notes exchanged, and the name of the registered holder of such Old
Notes, and must be signed by the holder in the same manner as the original
signature on the Letter of Transmittal (including any required signature
guarantees) or be accompanied by evidence satisfactory to the Company that the
person withdrawing the tender has succeeded to the beneficial ownership of the
Old Notes being withdrawn. The Exchange Agent will return the properly
withdrawn Old Notes promptly following receipt of notice of withdrawal. All
questions as to the validity of notices of withdrawals, including time of
receipt, will be determined by the Company and such determination will be
final and binding on all parties.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES
 
  Upon the terms and subject to the conditions of the Exchange Offer, the
acceptance for exchange of Old Notes validly tendered and not withdrawn and
the issuance of the Exchange Notes will be made on the Exchange Date.
 
  The Exchange Agent will act as agent for the tendering holders of the Old
Notes for the purposes of receiving Exchange Notes from the Company and
causing the Old Notes to be assigned, transferred and exchanged. Upon the
terms and subject to conditions of the Exchange Offer, delivery of Exchange
Notes to be issued in exchange for accepted Old Notes will be made by the
Exchange Agent promptly after acceptance of
 
                                      18
<PAGE>
 
the tendered Old Notes. Old Notes not accepted for exchange by the Company
will be returned without expense to the tendering holders (or in the case of
Old Notes tendered by book-entry transfer into the Exchange Agent's account at
the Book-Entry Transfer Facility pursuant to the procedures described above,
such non-exchanged Old Notes will be credited to an account maintained with
such Book-Entry Transfer Facility) promptly following the Expiration Date or,
if the Company terminates the Exchange Offer prior to the Expiration Date,
promptly after the Exchange Offer is so terminated.
 
CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other provision of the Exchange Offer, or any extension
of the Exchange Offer, the Company will not be required to issue Exchange
Notes in respect of any properly tendered Old Notes not previously accepted
and may terminate the Exchange Offer (by oral or written notice to the
Exchange Agent and by timely public announcement communicated by no later than
5:00 p.m. on the next business day following the Expiration Date, unless
otherwise required by applicable law or regulation, by making a release to the
Dow Jones News Service) or, at its option, modify or otherwise amend the
Exchange Offer, if (a) there shall be threatened, instituted or pending any
action or proceeding before, or any injunction, order or decree shall have
been issued by, any court or governmental agency or other governmental
regulatory or administrative agency or commission, (i) seeking to restrain or
prohibit the making or consummation of the Exchange Offer or any other
transaction contemplated by the Exchange Offer, (ii) assessing or seeking any
damages as a result thereof or (iii) resulting in a material delay in the
ability of the Company to accept for exchange some or all of the Old Notes
pursuant to the Exchange Offer; (b) any statute, rule, regulation, order or
injunction shall be sought, proposed, introduced, enacted, promulgated or
deemed applicable to the Exchange Offer or any of the transactions
contemplated by the Exchange Offer by any government or governmental
authority, domestic or foreign, or any action shall have been taken, proposed
or threatened, by any government, governmental authority, agency or court,
domestic or foreign, that in the reasonable judgment of the Company might
directly or indirectly result in any of the consequences referred to in
clauses (a)(i) or (ii) above or, in the reasonable judgment of the Company,
might result in the holders of Exchange Notes having obligations with respect
to resales and transfers of Exchange Notes that are greater than those
described in the interpretations of the Staff referred to on the cover page of
this Prospectus, or would otherwise make it inadvisable to proceed with the
Exchange Offer; or (c) a material adverse change shall have occurred in the
business, condition (financial or otherwise), operations, or prospects of the
Company.
 
  The foregoing conditions are for the sole benefit of the Company and may be
asserted by it with respect to all or any portion of the Exchange Offer
regardless of the circumstances (including any action or inaction by the
Company) giving rise to such condition or may be waived by the Company in
whole or in part at any time or from time to time in its sole discretion. The
failure by the Company at any time to exercise any of the foregoing rights
will not be deemed a waiver of any such right, and each right will be deemed
an ongoing right that may be asserted at any time or from time to time. In
addition, the Company has reserved the right, notwithstanding the satisfaction
of each of the foregoing conditions, to terminate or amend the Exchange Offer.
 
  Any determination by the Company concerning the fulfillment or
nonfulfillment of any conditions will be final and binding upon all parties.
 
  In addition, the Company will not accept for exchange any Old Notes
tendered, and no Exchange Notes will be issued in exchange for any such Old
Notes, if at such time any stop order shall be threatened or in effect with
respect to the Registration Statement of which this Prospectus constitutes a
part or qualification of the Indenture under the Trust Indenture Act of 1939,
as amended (the "Trust Indenture Act").

SOLICITATION OF TENDERS; EXPENSES
 
  The Company has not retained any dealer-manager or similar agent in
connection with the Exchange Offer and will not make any payments to brokers,
dealers or others for soliciting acceptances of the Exchange Offer. The
Company will, however, pay the Exchange Agent reasonable and customary fees
for its services and will reimburse it for reasonable out-of-pocket expenses
in connection therewith. The Company also will pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding tenders for their customers. The expenses to be
incurred in connection with the Exchange Offer, including the fees and
expenses of the Exchange Agent and printing, accounting, investment banking
and legal fees, will be paid by the Company and are estimated to be
approximately $130,568.
 
  No person has been authorized to given any information or to make any
representations in connection with the Exchange Offer other than those
contained in this Prospectus. If given or made, such information or
representations should not be relied upon as having been authorized by the
Company. Neither the delivery of this Prospectus nor any exchange made
hereunder shall, under any circumstances, create any implication that there
has been no change in the affairs of the Company since the respective dates as
of which information is given herein. The Exchange Offer is not being made to
(nor will tenders be accepted from or on behalf of) holders of Old Notes in
any jurisdiction in which the making of the Exchange Offer or the acceptance
thereof would not be in compliance with the laws of such jurisdiction.
However, the Company may, at its discretion, take such action as it may deem
necessary to make the Exchange Offer in any such jurisdiction and extend the
Exchange Offer to holders of Old Notes in such jurisdiction. In any
jurisdiction the securities laws or blue sky laws of which require the
Exchange Offer to be made by a licensed broker or dealer, the Exchange Offer
is being made on behalf of the Company by one or more registered brokers or
dealers that are licensed under the laws of such jurisdiction.
 
DISSENT AND APPRAISAL RIGHTS
 
  HOLDERS OF OLD NOTES WILL NOT HAVE DISSENTERS' RIGHTS OR APPRAISAL RIGHTS IN
CONNECTION WITH THE EXCHANGE OFFER.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The exchange of Old Notes for Exchange Notes by tendering holders will not
be a taxable exchange for federal income tax purposes, and such holders should
not recognize any taxable gain or loss as a result of such exchange. See
"Certain Federal Income Tax Considerations."
 
OTHER
 
  Participation in the Exchange Offer is voluntary and holders of Old Notes
should consider carefully whether to accept the terms and conditions thereof.
Holders of the Old Notes are urged to consult their financial and tax advisors
in making their own decisions on what action to take with respect to the
Exchange Offer.

  As a result of the making of and upon acceptance for exchange of all validly
tendered Old Notes pursuant to the terms of this Exchange Offer, the Company
will have fulfilled a covenant contained in the terms of the Old Notes and the
Registration Rights Agreement. Holders of the Old Notes who do not tender
their Old Notes in the Exchange Offer will continue to hold such Old Notes and
will be entitled to all the rights and limitations applicable thereto under
the Indenture, except for any such rights under the Registration Rights
Agreement that by their terms terminate or cease to have further effect as a
result of the making of this Exchange Offer. See "Description of the Notes."
All untendered Old Notes will continue to be subject to the restriction on
transfer set forth in the Indenture. To the extent that Old Notes are tendered
and accepted in the Exchange Offer, the trading market, if any, for any
remaining Old Notes could be affected adversely. See "Risk Factors--
Consequences of Failure to Exchange Old Notes."
 
  The Company may in the future seek to acquire untendered Old Notes in open
market or privately negotiated transactions, through subsequent exchange
offers or otherwise. The Company has no present plan to acquire any Old Notes
that are not tendered in the Exchange Offer.

    repurchase partially the Series 2D Senior Preferred Stock on December 30,
    1996.
(b) The proceeds from the issuance and sale of the Old Notes were used to
    repurchase partially the Series 2D Senior Preferred Stock on December 30,

    with issuance. The Old Notes have not been adjusted for the approximate
    $0.1 million value assigned to the warrants issued concurrently with the
    Old Notes.
(c) The Company repurchased the Series 2D Senior Preferred Stock with the net
    proceeds from the issuance of the Old Notes and borrowing under the Credit
    Facility.

    gain on the Disposition of PCI, expenses associated with the borrowing
    under the Credit Facility and the remaining accretion on the Series 2D
    Senior Preferred Stock. Common shareholders' equity has not been adjusted
    for the approximate $0.1 million value assigned to the warrants issued
    concurrently with the Old Notes. See "Unaudited Pro Forma Consolidated

                     SELECTED CONSOLIDATED FINANCIAL DATA
 
  The selected consolidated financial data of the Company for the ten months
ended December 31, 1995, and each year in the four-year period ended February
28, 1995, have been derived from the Company's audited consolidated financial
statements. This information should be read in conjunction with the
Consolidated Financial Statements and the related notes thereto appearing
elsewhere in this Prospectus and "Management's Discussion and Analysis of
Financial Condition and Results of Operations." The selected consolidated
financial data of the Company as of September 30, 1995 and 1996 and for the
nine-month periods then ended, have been prepared on the same basis as the
consolidated financial statements and, in the opinion of the Company, include
all normal and recurring adjustments (consisting of only normal recurring
adjustments) necessary to present fairly the information set forth therein.
Operating results for the nine months ended September 30, 1996 are not
necessarily indicative of the results that may be expected for the fiscal year
ended December 31, 1996. Certain reclassifications have been made to the prior
period financial statements to conform to the presentation used in the
September 30, 1996 financial statements. The data for the nine months ended
September 30, 1995 and 1996 set forth below are unaudited.

(1) Fiscal year 1992 reflects after-tax charge of $52.4 million associated
    with the disposal and restructuring of certain businesses.
(2) In fiscal year 1994, the Company adopted Statement of Financial Accounting
    Standards No. 106, "Employers' Accounting for Postretirement Benefits
    Other than Pensions."
(3) Service revenue is derived by deducting the costs of subcontracted
    services and direct project costs from gross revenue and adding the
    Company's share of the equity in income of unconsolidated joint ventures
    and affiliated companies.
(4) EBITDA represents operating income (loss), excluding unusual items, plus
    depreciation and amortization minus minority interests. Management
    believes that EBITDA is generally accepted as providing useful information
    regarding a company's ability to service and/or incur debt. EBITDA should
    not be considered in isolation or as a substitute for net income, cash
    flows or other consolidated income or cash flow data prepared in
    accordance with generally accepted accounting principles or as a measure
    of a company's profitability or liquidity.
(5) The ratio of earnings to fixed charges is calculated by dividing income
    from continuing operations before fixed charges and income taxes
    ("earnings") by fixed charges. Fixed charges consist of interest expense
    and that portion of rental expense that the Company believes to be
    representative of interest. In the years ended February 29, 1992 and
    February 28, 1994, earnings, as defined, were inadequate to cover fixed
    charges. The deficiencies were $54.3 million and $12.9 million for the
    years ended February 29, 1992 and February 28, 1994, respectively.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
  Column 1 has been prepared from the Company's historical consolidated
financial statements included elsewhere in this Prospectus. Column 2 has been
prepared from the Company's accounts and represents the effect of the
Disposition of PCI and the entities associated with the Disposition. Column 3
represents unaudited pro forma adjustments that the Company considers
necessary to give effect to the Pro Forma Transactions other than the
Disposition of PCI. Column 4 represents the unaudited pro forma results of
operations and financial position of the Company after giving effect to the
Pro Forma Transactions.
 
(a) To record the result of the issuance of the Old Notes that were used to
    repurchase partially the Series 2D Senior Preferred Stock on December 30,
    1996. Estimated professional fees and discount of $0.3 million associated
    with the issuance of the Old Notes are shown as if they were amortized
    over 96 months. The Old Notes and common shareholders' equity have not
    been adjusted for the approximate $0.1 million value assigned to the
    warrants issued concurrently with the Old Notes. Annual interest expense
    on the Old Notes is assumed to be 13%.
 
(b) To record the borrowings under the Credit Facility and associated
    expenses. The borrowings were used to repurchase the balance of the Series
    2D Senior Preferred Stock on December 30, 1996.
 
(c) To record the result of the repurchase of the Series 2D Senior Preferred
    Stock and the reversal of the effects of the associated dividends and
    accretion.
 
(d) To record, as a result of the Pro Forma Transactions, the effect of the
    reduction in interest expense of the Credit Facility. It is assumed that a
    portion of the cash provided by the Pro Forma Transactions will be used to
    repurchase the Series 2D Senior Preferred Stock, that the balance will be
    reinvested in the Company's business activities and that such activities
    will provide funds to allow the Company to reduce borrowings under the
    Credit Facility.
 
(e) To record the net effect on the income tax provision.
 
(f) EBITDA represents operating income (loss), excluding unusual items, plus
    depreciation and amortization minus minority interests. Management
    believes that EBITDA is generally accepted as providing useful information
    regarding a company's ability to service and/or incur debt. EBITDA should
    not be considered in isolation or as a substitute for net income, cash
    flows or other consolidated income or cash flow data prepared in
    accordance with generally accepted accounting principles or as a measure
    of a company's profitability or liquidity.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  The Company is one of the nation's largest engineering, construction,
program management and consulting services companies, providing fully
integrated capabilities to clients in three related market areas: environment,
infrastructure and basic metals and mining industries. The Company provides
services to domestic and foreign clients in both the private and public
sectors.
 
 Change in Fiscal Year
 
  The Company changed from a fiscal year ending February 28 to a fiscal year
ending December 31, effective December 31, 1995. As a result, the accompanying
financial statements include consolidated operations for the ten months ended
December 31, 1995 and for the years ended February 28, 1995 and 1994. See Note
S to the consolidated financial statements for the ten months ended December
31, 1995 for unaudited comparative operating results for the ten months ended
December 31, 1994. In addition, the comparative period financial statements
for the nine months ended September 30, 1995 have been restated to conform
with the presentation used in the September 30, 1996 financial statements.
 
 Operating Results for Nine Months Ended September 30, 1996 and 1995
 
  The Company's operating income of $21.2 million for the nine months ended
September 30, 1996 was an $8.0 million increase from the $13.2 million of
operating income recorded for the nine months ended September 30, 1995. The
increase in operating income partially resulted from a $3.9 million increase
in operating income from the Company's operations at DOE's Hanford site,
resulting from higher award fees earned at Hanford in 1996 and activities
associated with the final phase of the Company's work at Hanford (see
"Business Outlook"). An additional $6.8 million of the increase in operating
income was due to earnings (before minority interests) from the Performance
Based Integrating Management Contract at DOE's Rocky Flats Environmental
Technology Site in Colorado ("Rocky Flats"). The Rocky Flats contract was
awarded in April 1995 to Kaiser-Hill Company, LLC ("Kaiser-Hill"), a limited
liability company owned equally by ICF Kaiser and CH2M Hill Companies, Ltd.
("CH2M Hill"). Work under the Rocky Flats contract began on July 1, 1995.
 
  Operating income for the Company's consulting group increased $1.3 million
from 1995 to 1996, primarily due to new contracts and task orders awarded
during 1996 and the recognition of revenue resulting from the acceleration in
the cost approval process (see Note B to the consolidated financial statements
for the nine months ended September 30, 1996). Prior to the third quarter of
1996, the Company had estimated and recorded revenue based on provisional
rates. In 1996, the Company accelerated the procedures for obtaining approval
from the U.S. government for the Company's actual costs incurred in current
periods. As a result, in the third quarter of 1996, the Company's consulting
group was able to accelerate its process of billing on certain cost-
reimbursement contracts.
 
  The Company's operating income also increased $2.3 million for the nine
months ended September 30, 1996 from the comparable period in 1995 as a result
of the 1996 closing of an unprofitable business, and $1.1 million due to
income from the Company's increased economic interest in an entity that owns
the PCI facility. Additionally, the Company realized cost savings of certain
corporate functions, resulting in an improvement in operating income in 1996.
Finally, operating income from international operations increased $0.8
million, primarily due to improved operating results from the Company's
Australian operations.
 
  Partially offsetting the operating income increases discussed above were
declines of $4.6 million in operating income from engineering and construction
operations and $4.2 million in operating income from other federal programs.
The federal programs group had significant increases in its costs associated
with marketing activities in pursuit of large-scale projects, including
approximately $2.1 million of costs in 1996 associated with
 
                                      29
<PAGE>
 
the Company's unsuccessful re-compete bid on the Hanford contract (see "--
Business Outlook") and significant costs associated with other DOE proposals.
The engineering and construction group also experienced higher costs in 1996
associated with marketing activities. In addition, the comparative 1995
results for engineering and construction operations had included operating
income from a major transit project in the Philippines.
 
 Operating Results for Ten Months Ended December 31, 1995 and 1994
 
  ICF Kaiser's operating income of $17.5 million for the ten months ended
December 31, 1995 was a $4.6 million increase from the $12.9 million recorded
for the ten months ended December 31, 1994. The increase in operating income
(before minority interests) primarily resulted from a $5.7 million improvement
in engineering and construction operations and $5.3 million in earnings from
the Rocky Flats contract awarded in April 1995 to Kaiser-Hill. The improvement
in engineering and construction operations was partially due to a major
transit project in the Philippines, operating revenue of which had been
previously deferred. Other improvements in engineering and construction
operations were due to substantial growth in the group's industrial sector and
a reduction in the group's overhead.
 
  An additional $3.0 million increase in operating income resulted from the
Company's operations at Hanford because the award fees earned in 1995 were
higher than those earned in 1994.
 
  A $4.9 million decline in the Company's operating income from other
environmental work (excluding the Rocky Flats and Hanford contracts) partially
offset the improvements in operating income discussed above between the ten-
month periods ended December 31, 1995 and 1994. This decrease in other
environmental operations was primarily due to a decline in operating income
from private-sector environmental work, increases in bidding and proposal
efforts required by large scale DOD and DOE contracts, and temporary delays in
Federal environmental projects due to Federal government budgetary
uncertainties.
 
  The Company's consulting operations also experienced a decline in operating
revenues between the ten-month periods ended December 31, 1995 and 1994,
resulting in a $0.9 million decrease in operating income for this group. The
decrease was caused by a delay in task-order assignments under new contract
awards and a significant increase in levels of business development activity.
The Federal government's fiscal 1996 budget was not finalized during the ten
months ended December 31, 1995, which led to the Federal governments operating
under a continuing resolution (including two no-work furlough periods) since
October 1, 1995. While under this resolution, the assignment of work under
task-order contracts was delayed.
 
  A significant company-wide increase in marketing efforts further negatively
impacted operating results for the ten months ended December 31, 1995 as
compared to the ten months ended December 31, 1994. These efforts were in
addition to the marketing activities discussed above within the environmental
and consulting operations. The Company believes that ICF Kaiser's increased
efforts in its business development activities should result in additional
contract awards in both the public and private sectors of its business.
 
 Business Outlook
 
  The Company's contract backlog increased significantly to $4.4 billion at
December 31, 1995 compared to $1.4 billion at February 28, 1995. The increase
in backlog primarily resulted from the April 1995 award of the Rocky Flats
contract, which added $3.0 billion to contract backlog. The fee structure for
this five-year contract provides for a mixture of base and incentive fees
earned through the achievement of cost reductions, attainment of certain
milestones, and accomplishment of other goals. In August 1995, ICF Kaiser
signed a contract estimated at $330 million to perform environmental
restoration work at Federal installations for the U.S. Army Corps of Engineers
("USACE"), Baltimore District. This Total Environmental Restoration Contract
("TERC") is for four years with two, three-year options. The contract is a
cost reimbursement delivery order contract, and the fee structure includes a
combination of cost plus fixed fee, award fee, and incentive fees. In August
1995, ICF Kaiser also signed a five-year contract estimated at $50 million to
provide environmental services to USACE, Savannah District.
 
 
                                      30
<PAGE>
 
  The Company's contract backlog was $3.9 billion at September 30, 1996
compared to $4.4 billion at December 31, 1995. The overall reduction in
backlog is primarily due to Hanford (see below). In September 1996, the
Company signed another TERC contract estimated at $260 million to perform
environmental restoration work at federal installations in the South Pacific
Division of the U.S. Army Corps of Engineers, Sacramento District. The TERC
contract is for four years, with two, three-year options and is a cost
reimbursement delivery order contract. The fee structure includes a
combination of cost plus fixed fee, award fee, and incentive fees. In
September 1996, the Company also signed a five-year contract, valued at more
than $60 million, to support EPA's Green Lights and ENERGY STAR programs.
 
  In March 1996, the Company signed a two-year, $102 million contract to
provide engineering and construction services for the initial phase of a mini-
mill project for Nova Hut, an integrated steel maker based in the Ostrava
region of the Czech Republic. The Company is currently negotiating a contract
with Nova Hut for the next phase of the mini-mill project. Earnings associated
with this contract for the next phase of work are expected to be material to
the Company's operating results. Management expects to complete negotiations
on this contract in the first quarter of 1997.
 
  The Company has sold its interest in entities owning and operating the PCI
facility, the earnings and cash flows from which have been significant to the
Company, in order to improve the Company's cash position in light of
substantial near-term cash requirements (see "--Liquidity and Capital
Resources"). The closing occurred in December 1996. The sale will result in a
gain in the period in which the sale was finalized. The Company anticipates
that any cash proceeds resulting from the sale that are not used to satisfy
the substantial near-term cash requirements will be reinvested in the
Company's business. See "Unaudited Pro Forma Consolidated Financial
Statements."
 
  In August 1996, the Company, through its subsidiary, ICF Kaiser Hanford
Company, was informed that the team of which it was a member was unsuccessful
in its bid for DOE's new management and integration contract at Hanford. The
new contract was effective October 1, 1996. The Company's existing contract to
perform services at Hanford expires in March 1997, but was effectively
terminated by DOE on October 1, 1996. As a result, and based on the Company's
current assessment of the closeout of the Hanford contract, management
believes the impact on earnings will be material in the fourth quarter of
1996, as well as future periods, unless replaced. In response to the reduction
and eventual elimination of the Hanford contract, in August 1996 the Company
initiated a significant operational efficiency and cost savings program,
together with management changes, with the objective of minimizing the long-
term impact associated with the termination of the Hanford contract. To date,
the results of the cost savings program have been encouraging. Termination of
the Hanford contract is not expected to significantly impact cash flows in the
fourth quarter but may have a significant impact after 1996 if the cost
savings program is not successful (see "--Liquidity and Capital Resources").
Profitable operating results in the fourth quarter of fiscal year 1996 are
dependent on the success of the Company's ongoing marketing efforts (including
Nova Hut), results from the cost savings program discussed above, and a gain
on sale of the entities owning and operating PCI.
 
  The Company's consulting group showed improvement in operating results
between the nine-month periods ended September 30, 1996 and 1995, aided by the
recognition of revenue resulting from the accelerated cost approval process
(see "--Overview--Operating Results for Nine Months Ended September 30, 1996
and 1995"). EPA historically has been the consulting group's principal federal
government customer; for several years the consulting group has been
diversifying its client base to international, private sector, and non-EPA
federal government entities. EPA now accounts for only approximately 50% of
the consulting group's service revenue. In 1996, the consulting group
increased its business development efforts to diversify its client base and
expects to make further progress in diversification in 1997.
 
  As discussed in Operating Results, the Company's domestic engineering and
construction business has not met its financial goals during 1996. As a
result, the Company continues in its efforts to enhance profitability of these
operations. These efforts include both a continuation of cost reduction
efforts and increases in marketing. In conjunction with the cost reduction
efforts the Company has recently completed a realignment of several of
 
                                      31
<PAGE>
 
its offices, including the termination of certain underutilized employees (see
Note G to the consolidated financial statements for the nine months ended
September 30, 1996). The Company will continue to seek other opportunities to
save costs, and future actions may include additional office space
consolidations and terminations.

  Gross revenue represents services provided to customers with whom the
Company has a primary contractual relationship. Included in gross revenue are
costs of certain services subcontracted to third parties and other
reimbursable direct project costs, such as materials procured by the Company
on behalf of its customers.
 
  Service revenue is derived by deducting the costs of subcontracted services
and direct project costs from gross revenue and adding the Company's share of
the equity in income of unconsolidated joint ventures and affiliated
companies. The Company believes that it is appropriate to analyze operating
margins and other ratios in relation to service revenue because such revenue
and ratios reflect the work performed directly by the Company.
 
  Operating profits (fees) generated by the Hanford and Rocky Flats contracts
are based on performance and not revenue. A change in revenue between periods
is likely to be disproportionate to the change in the fees earned.
Consequently, changes in revenue may have an exaggerated impact on the
Company's margins as measured on a percentage basis. In addition, because
Kaiser-Hill is a consolidated subsidiary of the Company effective July 1,
1995, operating income includes the portion of income generated under the
Rocky Flats contract attributable to CH2M Hill. CH2M Hill's interest in
Kaiser-Hill is reflected as a minority interest in subsidiaries in the
Company's financial statements (see Note C to the consolidated financial
statements for the nine months ended September 30, 1996.)
 
 Nine Months Ended September 30, 1996 Versus Nine Months Ended September 30,
1995
 
  Revenue. Gross revenue for the nine months ended September 30, 1996
increased $291.6 million, or 39.8%, to $1,023.4 million. The increase in gross
revenue was primarily attributable to the commencement of work under the Rocky
Flats contract which generated a $291.8 million increase in gross revenue
during the nine months ended September 30, 1996.
 
 
                                      32
<PAGE>
 
  Service revenue increased by $76.0 million for the nine-month period ended
September 30, 1996 as compared to the nine-month period ended September 30,
1995. The increase was due primarily to an $82.3 million increase in service
revenue generated under the Rocky Flats contract. Service revenue as a
percentage of gross revenue decreased to 42.4% for the nine months ended
September 30, 1996 from 48.9% for the nine months ended September 30, 1995.
The decrease in service revenue as a percentage of gross revenue is a result
of the nature of the Rocky Flats contract. A significant portion of the gross
revenue derived from the Rocky Flats contract includes the costs of services
subcontracted to third parties.
 
  Operating Expense. Direct cost of services and overhead increased $56.2
million between the nine-month periods ended September 30, 1996 and 1995. A
$74.4 million increase in costs on the Rocky Flats contract was partially
offset by a $13.0 million reduction in Hanford costs attributable to federal
budget reductions at the Hanford site. The Company's direct cost of services
and overhead as a percentage of service revenue for the nine months ended
September 30, 1996 was comparable to the same period in the prior year.
 
  Administrative and general expense increased $11.4 million, or 29.4%,
between the nine-month periods ended September 30, 1996 and 1995 and increased
from 10.8% to 11.5% as a percentage of service revenue. The increase in these
costs is primarily attributable to the Company's increased commitment to
marketing activities in 1996, including costs associated with new marketing
positions within the Company and proposing and bidding large-scale domestic
and foreign contracts. The increase in administrative and general expenses as
a percentage of service revenue resulting from increased marketing efforts was
partially offset as a result of the increase in service revenue in 1996 from
the Rocky Flats contract which does not have a proportionate increase in
administrative and general expenses.
 
  Income Tax Expense. The Company's income tax provision was $0.8 million for
the nine months ended September 30, 1996 compared with $1.3 million for the
nine months ended September 30, 1995. The income tax provision for the nine
months ended September 30, 1996 reflects a partial reversal of the valuation
allowance for certain deferred tax assets. This partial reversal reduced tax
expense by approximately $2.0 million for the nine-month period. The Company
expects to have significant taxable income in the near-term from the sale of
certain subsidiaries (see "--Business Outlook"). The remaining valuation
allowance after this partial reversal in 1996 is for foreign tax benefits not
currently assured of realization. Also, the income tax provision for the nine
months ended September 30, 1996 was computed by excluding the minority
interest in Kaiser-Hill's income because Kaiser-Hill is a flow-through entity
for tax purposes and is partially owned by an outside party. This and the
partial reversal of the valuation allowance had the effect of reducing the
Company's effective tax rate. Since Kaiser-Hill commenced operations on July
1, 1995, its effect on the effective tax rate was relatively larger in the
nine months ended September 30, 1996 than in 1995.
 
 Ten Months Ended December 31, 1995 Versus Ten Months Ended December 31, 1994
 
  Revenue. Gross revenue for the ten months ended December 31, 1995 increased
$184.3 million, or 25.2%, to $916.7 million. The increase in gross revenue was
attributable to the commencement of work under the Kaiser-Hill contract which
generated $277.7 million in gross revenue during the ten-month period. The
increase was partially offset by a $98.6 million reduction in gross revenue
under the Hanford contract due to Federal budget reductions at the Hanford
site.
 
  Service revenue increased by $33.9 million for the ten-month period ended
December 31, 1995 as compared to the ten months ended December 31, 1994. The
increase was due primarily to $91.2 million of service revenue generated under
the Rocky Flats contract, offset by a $57.8 million decrease in service
revenue under the Hanford contract. Service revenue as a percentage of gross
revenue decreased to 46.5% for the ten months ended December 31, 1995 from
53.5% for the ten months ended December 31, 1994 as a result of the nature of
the Rocky Flats contract. A significant portion of the gross revenue derived
from the Rocky Flats contract includes the costs of services subcontracted to
third parties.
 
  Operating Expenses. Direct cost of services and overhead increased $22.8
million between the ten-month periods ended December 31, 1995 and 1994. Costs
on the new Rocky Flats contract ($85.3 million) were offset
 
                                      33
<PAGE>
 
by a $60.9 million reduction in the Hanford contract costs (attributable to
the Federal budget reductions discussed above). The remainder of the Company's
direct cost of services and overhead as a percentage of service revenue for
the ten months ended December 31, 1995 was comparable to the same period in
the prior year.
 
  Administrative and general expenses increased $6.4 million, or 18.5%,
between the ten-month periods ended December 31, 1995 and 1994 and increased
from 8.7% to 9.5% as a percentage of service revenue. The increase in these
costs was primarily attributable to the Company's increased marketing
activities, including filling several key marketing positions and incurring
relatively high levels of marketing expense associated with proposing and
bidding large-scale DOD and DOE contracts.
 
  Interest Expense. ICF Kaiser's average debt outstanding and average
effective interest rate for the ten months ended December 31, 1994 and 1995
were as follows.

     Average effective interest rate................         12.8%         12.9%
</TABLE>
 
  The average effective interest rate was comparable between the ten-month
periods ended December 31, 1995 and 1994 due to consistent interest rates and
indebtedness outstanding between the ten-month periods. The Company's
principal debt outstanding consists of the Existing Notes (see "--Liquidity
and Capital Resources").
 
  Income Tax Expense. ICF Kaiser's income tax provision was $2.1 million and
$3.0 million for the ten months ended December 31, 1995 and 1994,
respectively. Although pretax income for the ten months ended December 31,
1995 was $3.5 million greater than pretax income for the comparable period
ended December 31, 1994, the Company's effective tax rate decreased due to a
reduction in permanent differences (such as the nondeductibility of goodwill)
as a percentage of pretax income, increased foreign tax benefits, and minority
interest earnings of a consolidated subsidiary (see Note H to the consolidated
financial statements for the ten months ended December 31, 1995). The ten
months ended December 31, 1994 also included a repatriation of overseas funds
to the United States which could not then be currently offset by foreign tax
credits, resulting in additional income taxes for that period (see "--Results
of Operations--Year Ended February 28, 1995 Versus Year Ended February 28,
1994--Income Tax Expense").
 
  Because of the reported losses for the year ended February 28, 1994, a $3.3
million valuation allowance was established in that year for deferred tax
assets. Although the level of pretax income has increased substantially since
that period (with a corresponding increase in taxable income), the Company
maintained the valuation allowance as of December 31, 1995. At December 31,
1995, the Company had deferred tax assets of $0.7 million related to net
operating loss carryforwards, of which $0.5 million expire in the next five
years and $0.2 million expire in 2008. Additionally, the Company had deferred
tax assets of $2.1 million related to tax credit carryforwards, the majority
of which expire in 1998 to 2009.
 
  Unusual Items. During the ten months ended December 31, 1995, the Company
recorded $0.5 million in additional income (net), consisting of the following
unusual items: income in settlement of litigation against the Internal Revenue
Service ("IRS"), associated with an affiliate of an acquired company, net of
an accrual for related expenses ($6.8 million) (see "--Liquidity and Capital
Resources"); a charge to accrue the net settlement cost and legal expenses of
other litigation ($4.6 million); a charge to accrue for severance for the
termination of 110 employees in the engineering and international groups ($1.0
million); and a charge to accrue for consolidation of office space ($0.7
million). Management expects that all actions associated with the termination
of employees and office space consolidation will be completed by December 31,
1996.
 
  Year Ended February 28, 1995 Versus Year Ended February 28, 1994
 
  Revenue. Gross revenue for the year ended February 28, 1995 increased 32.2%
to $861.5 million, while service revenue increased 20.1% to $459.8 million,
versus the year ended February 28, 1994. These increases
 
                                      34
<PAGE>
 
were attributable to the work performed at Hanford ($208.8 million of the
gross revenue increase and $97.4 million of the service revenue increase). The
Hanford revenue increases were offset partially by a decrease in the Company's
engineering and construction revenue ($14.1 million gross revenue and $10.8
million service revenue).
 
  Service revenue as a percentage of gross revenue decreased to 53.4% for the
year ended February 28, 1995, from 58.7% for the previous year, primarily
because under an October 1993 amendment to the Hanford contract, the Company
absorbed tasks utilizing a much higher proportion of subcontractors than
Company personnel.
 
  Operating Expenses. The Company's direct cost of services and overhead was
relatively flat as a percentage of service revenue for the year ended February
28, 1995 versus the previous year. Excluding Hanford, direct cost of services
and overhead decreased to 76.2% of service revenue for the year ended February
28, 1995 from 79.2% for the year ended February 28, 1994. Administrative and
general expense decreased $2.1 million. The decrease in these costs was
attributable primarily to management cost-cutting initiatives.
 
  A restructuring plan initiated during the year ended February 28, 1994 to
respond to operating losses included downsizing the work force, consolidating
office space, renegotiating significant leases, and restructuring certain
international operations. All actions have been completed, and there is no
further liability outstanding as of December 31, 1995 associated with this
plan.
 
  Interest Expense. ICF Kaiser's interest expense net of interest income (net
interest) for the year ended February 28, 1995, increased $6.3 million from
the prior year due to a recapitalization that took place in the fourth quarter
of the year ended February 28, 1994 (see "--Liquidity and Capital Resources").
The increase in net interest was impacted favorably by $1.3 million in refunds
of interest from the IRS recorded in the third quarter of the year ended
February 28, 1995 associated with the Company's tax liabilities and those of
an acquired company. The increase in net interest was offset partially by a
reduction in preferred stock dividends.
 
  Income Tax Expense. The Company's income tax provision for the year ended
February 28, 1995 was $2.9 million, even though pretax income was $1.2
million. This is due to several factors including the deemed dividend from the
repatriation of overseas funds to the United States during the year ended
February 28, 1995 that currently could not be offset by foreign tax credits
and permanent differences, such as the nondeductibility of goodwill
amortization. Nondeductible permanent differences comprised a very high
percentage of pretax income. As such, the traditional percentage relationship
between income tax expense and pretax income was not meaningful.
 
LIQUIDITY AND CAPITAL RESOURCES
 
 Cash Flows for Nine Months Ended September 30, 1996
 
  During the nine months ended September 30, 1996, cash and cash equivalents
increased $4.7 million to $21.0 million. Operating activities generated $5.9
million in cash, primarily from operations at Kaiser-Hill which generated $8.8
million. An additional significant operating source of cash was $7.0 million
received from the IRS in settlement of litigation (see "--Results of
Operations--Ten Months Ended December 31, 1995 Versus Ten Months Ended
December 31, 1994--Unusual Items"). Significant operating uses of cash
included $15.4 million in interest payments on the Company's Existing Notes, a
$3.7 million pension payment, and $4.2 million of payments for net settlement
costs and legal expenses of litigation.
 
  The increase in contract receivables, net between December 31, 1995 and
September 30, 1996 was primarily due to an increase in receivables under the
Hanford contract resulting from the closeout of the contract. The decrease in
prepaid expenses and other current assets in 1996 was attributable to
collection from the IRS of $7.0 million, which was accrued in other current
assets at December 31, 1995. The cash received from the IRS settlement is
included in unusual items on the Statement of Cash Flows.

  During the nine months ended September 30, 1996, net borrowings under the
Company's Credit Facility provided $8.0 million in cash (see Note E to the
consolidated financial statements for the nine months ended September 30,
1996). Borrowings under the Credit Facility were used to fund operations
(including the pension payment made in September 1996). Other significant uses
of cash in investing and financing activities included purchases of fixed
assets ($4.9 million), payment of dividends ($2.0 million), and investments in
joint ventures and affiliates ($1.2 million ).
 
  In July 1996, EPA approved the Company's provisional billing rates for the
year ended February 28, 1995. This approval permitted the Company to submit
invoices for billing rate variances on cost-plus contracts with U.S.
government agencies for costs incurred during that year. The Company expects
to collect in excess of $1.5 million on these billings in future periods. In
October 1996, the Company also obtained approval for provisional billing rates
for the ten months ended December 31, 1995 which is expected to result in more
than $2.0 million in additional invoicing.
 
 Cash Flows for Ten Months Ended December 31, 1995
 
  During the ten months ended December 31, 1995, cash and cash equivalents
decreased $11.9 million to $16.4 million. Cash was primarily used in investing
and financing activities for acquisitions and investments in joint ventures
and affiliates ($2.0 million); purchases of fixed assets ($1.8 million);
payments of dividends ($1.5 million); repurchases by the Company's insurance
subsidiary of a portion of the Company's outstanding Existing Notes and
related warrants ($1.4 million); and payments of other outstanding debt ($1.2
million). In addition, $6.1 million was used in operating activities. An
interest payment of $7.5 million on the Company's Existing Notes was made in
June 1995. An additional $7.5 million interest payment on the Existing Notes
was due and paid on January 2, 1996.
 
  An increase in contract receivables, net between February 28, 1995 and
December 31, 1995 was primarily due to $71.9 million in receivables from the
commencement of work by Kaiser-Hill under the Rocky Flats contract. An
increase in accounts payable, accrued expenses, and accrued salaries and
employee benefits was also primarily due to the Rocky Flats contract which had
$70.6 million of accounts payable, accrued expenses, and accrued salaries and
employee benefits as of December 31, 1995.
 
  During the year ended February 28, 1995, the EPA approved the Company's
revised provisional billing rates for fiscal years 1991 through 1994, thus
authorizing the Company to submit invoices on cost-plus contracts with U.S.
government agencies for work performed during these approved years. The
Company collected in excess of $4 million as of December 31, 1995 on these
contracts.
 
 Liquidity and Capital Resources Outlook
 
  Effective May 7, 1996, the Company's new $40 million Credit Facility
replaced the then-existing revolving credit facility which was due to expire
October 31, 1996. The Credit Facility contains Eurodollar and alternate base
interest rate alternatives with margins dependent upon the Company's financial
operating results and expires June 30, 1998. Effective December 17, 1996, the
Company signed an amendment to the Credit Facility (the "Amendment") that
approved the Disposition of PCI, provided for a temporary $5.0 million Over
Advance Provision (as defined in the Amendment) and permitted the net proceeds
from the issuance of the Old Notes and borrowings under the Over Advance
Provision to be used to redeem the Series 2D Senior Preferred Stock. See
"Description of the Credit Facility."
 
  The Credit Facility is provided by CoreStates Bank, N.A. as agent bank, and
two other banks (the "Banks") with terms and covenants similar to those under
the former credit facility. ICF Kaiser International, Inc. and certain of its
subsidiaries, which are guarantors of the Credit Facility, granted the Banks a
security interest in their accounts receivable and certain other assets,
including the pledge of the stock of certain subsidiaries. The Credit Facility
limits the payments of cash dividends on common stock and requires the
maintenance of specified financial ratios. Total available credit is
determined from a borrowing base calculation based on eligible accounts
 
                                      36
<PAGE>
 
receivable (billed and unbilled). As of September 30, 1996, the Company had
$13.0 million in cash borrowings and $21.3 million of letters of credit
outstanding under the Credit Facility. The letters of credit outstanding under
the Credit Facility are generally required to support performance guarantees,
primarily on international projects. The Company had $5.7 million of
additional credit available under the Credit Facility as of September 30,
1996. As of January 7, 1997, the Company had no cash borrowings outstanding,
$18.6 million of letters of credit outstanding and the additional credit
available under the Credit Facility was $21.4 million.
 
  Kaiser-Hill has a $50 million receivables purchase facility to support its
working capital requirements under the Rocky Flats contract. The receivables
purchase facility requires Kaiser-Hill to maintain a specified tangible net
worth and contains certain default provisions for delinquent receivables.
Program fees consist of 0.30% per annum of the unused portion of the facility
and 0.45% per annum of the used portion of the facility. The receivables
purchase facility is non-recourse to Kaiser-Hill's owners, ICF Kaiser and CH2M
Hill, and expires on June 30, 1998.
 
  The Company has sold its interest in the entities owning and operating PCI,
the earnings and cash flows from which have been significant to the Company
(see "--Overview--Business Outlook").
 
  In January 1994, the Company issued its Existing Notes and 600,000 warrants,
each to purchase one share of the Company's common stock at $5.00 per share.
The net proceeds of the $125 million offering were used, in part, to retire
senior subordinated notes and associated warrants, to repurchase preferred
stock, and to repay the outstanding balance on the Company's then-existing
revolving credit facility. The recapitalization resulted in a $6.0 million
extraordinary charge (net of $0 tax benefit) for the early extinguishment of
debt and a $1.9 million charge to net income available for common shareholders
to repurchase redeemable preferred stock. As noted above, in November 1995,
the Company's insurance subsidiary repurchased $1,450,000 of the Existing
Notes and related warrants for $1.4 million. In March 1996, the interest rate
on the Existing Notes was increased by one percent until the Company achieves
and maintains a specified level of earnings (see Notes F and I to the
consolidated financial statements for the ten months ended December 31, 1995).
The Existing Notes mature on December 31, 2003 with semi-annual interest
payments.
 
  The Company's Series 2D Senior Preferred Stock was subject to mandatory
redemption on January 13, 1997 in the amount of $20 million plus accrued
dividends. Because of technical limitations on the payment of dividends
contained in the Existing Indenture, the Company did not pay the November 30,
1995 and February 29, 1996 accrued dividends in the aggregate amount of
$975,000 until March 1996, following the signing of an amendment to the
Indenture governing the Existing Notes which permitted the payment of all
accrued and future dividends. As consideration for this amendment, the
interest rate on the Existing Notes was increased as discussed above. The
Company repurchased this preferred stock using the net proceeds of the
issuance of the Old Notes and borrowings under the Credit Facility.
 
  As explained in "--Overview--Business Outlook," the loss of the Hanford
contract may have a significant impact on the Company's cash flows after 1996
if the Company's cost savings and marketing programs are not successful. The
Company believes it will be successful in its ability to generate adequate
cash flows to fund operations throughout the next twelve months and in
reducing overhead costs within the operating groups and corporate functions.
 
IMPACT OF NEW ACCOUNTING STANDARDS
 
  The Financial Accounting Standards Board (FASB) recently issued Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," effective for
financial statements for fiscal years beginning after December 15, 1995. It is
the Company's current policy to evaluate all long-lived assets on a periodic
basis for asset impairment. Therefore, the adoption of this statement has no
material adverse effect on the Company's financial position or operations.
 
 
                                      37
<PAGE>
 
  The FASB also recently issued Statement of Financial Accounting Standards
No. 123, "Accounting for Stock-Based Compensation" ("SFAS No. 123"), which
encourages companies to adopt a fair value method of accounting for employee
stock options and similar equity instruments. The fair value method requires
compensation cost to be measured at the grant date based on the value of the
award and is recognized over the service period. Alternatively, SFAS No. 123
requires the provision of pro forma disclosures of net income and earnings per
share as if the fair value method had been adopted when the fair value method
is not reflected in the financial statements. The Company has elected to
provide pro forma disclosures. Therefore, the adoption of SFAS No. 123 will
not have a material adverse effect on the Company's financial position or
result of operations. The requirements of SFAS No. 123 are effective for
financial statements for fiscal years beginning after December 15, 1995.

                                   BUSINESS
 
 
  ICF Kaiser International, Inc., through ICF Kaiser Engineers, Inc. and its
other operating subsidiaries, is one of the nation's largest engineering,
construction, program management and consulting services companies. The
Company's Federal Programs, Engineers and Consulting Groups provide fully
integrated services to domestic and foreign clients in the private and public
sectors of the environment, infrastructure and basic metals and mining
industry markets. For the latest twelve-month period ended September 30, 1996,
ICF Kaiser had gross and service revenue of $1,337.5 million and $569.8
million, respectively, and EBITDA (as defined) of $30.8 million. Service
revenue is derived by deducting the costs of subcontracted services and direct
project costs from gross revenue and adding the Company's share of income
(loss) of joint ventures and affiliated companies. As of November 30, 1996,
the Company employed 5,176 people located in more than 80 offices worldwide.
 
  The Company was incorporated in Delaware 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 1988, the Company acquired
the Kaiser Engineers business, which dates from 1914. The Company's
headquarters is located at 9300 Lee Highway, Fairfax, Virginia 22031-1207,
telephone number (703) 934-3600.
 
OVERVIEW OF MARKETS
 
  Environmental. In the environmental market, the Company provides services in
connection with the remediation of hazardous and radioactive waste, waste
minimization and disposal, risk assessment, global warming and acid rain,
alternative fuels and clean up of harbors and waterways. Demand for ICF
Kaiser's environmental consulting and engineering services is driven by a
number of factors, including: the need to improve the quality of the
environment; federal, state and municipal environmental regulation and
enforcement; and increased liability associated with pollution-related injury
and damage. Increasingly strict federal, state, and local government
regulation has forced private industry and government agencies to clean up
contaminated sites, to bring production facilities into compliance with
current environmental regulations, and to minimize waste generation on an
ongoing basis. In addition, ICF Kaiser is well-positioned to take advantage of
the growing market arising from the increased awareness internationally of the
need for additional and/or initial environmental regulations, studies and
remediation.
 
  Significant environmental laws have been enacted in response to public
concern about the environment. These laws and the implementing regulations
affected nearly every industrial activity, and efforts to comply with the
requirements of these laws create demand for the Company's services. The
principal Federal legislation that has created a substantial market for the
Company, and therefore has the most significant effect on the Company's
business, includes the following: The Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") of 1980, as amended by the Superfund
Amendments and Reauthorization Act ("SARA") of 1986, established the Superfund
program to clean up existing, often abandoned hazardous waste sites and
provides for penalties and punitive damages for noncompliance with the EPA
orders. The Resource Conservation and Recovery Act ("RCRA") of 1976, as
amended by the Hazardous and Solid Waste Amendments of 1984 ("HSWA"), provides
a comprehensive scheme for the regulation of hazardous waste from the time of
generation to its ultimate disposal (and sometimes thereafter), as well as the
regulation of persons engaged in the treatment, storage and disposal of
hazardous waste. The Clean Air Act as amended in 1970 empowered the EPA to
establish and enforce National Ambient Air Quality Standards, National
Emission Standards for Hazardous Air Pollutants and limits on the emission of
various pollutants. The 1990 amendments to the Clean Air Act substantially
increase the number of sources emitting a regulated air pollutant which will
be required to obtain an operating permit; the amendments also address the
issues of acid rain, ozone protection, and other areas in which the Company
can provide expanded services. The Clean Water Act of 1972, originally the
Federal Water Pollution Control Act of 1948, established a system of
standards, permits and enforcement procedures for the discharge of pollutants
to surface water from industrial, municipal, and other wastewater sources. The
Toxic Substance Control Act, enacted in 1976, established requirements for
identifying and controlling toxic chemical hazards to human health and the
environment.
 
                                      39

  Infrastructure. The global infrastructure market is driven by the need to
maintain and expand among other things, ports, roads, highways, mass transit
systems and airports. Increasingly, environmental concerns, such as wastewater
treatment and reducing automotive air pollutant emissions, have become a
driving force behind new infrastructure and transportation initiatives. This
market is primarily funded by government dollars, although the private sector
is seeking an increased role, particularly in international projects. The
Company has capitalized on its specialized technical and environmental skills
to win projects that provide consulting, planning, design and construction
services. Internationally, there is a critical need for infrastructure
projects where population growth of major cities has been and will continue to
be extremely high. The Company provides engineering and construction
management services for mass transit and wastewater treatment facilities in
major metropolitan areas worldwide.
 
  Industry. ICF Kaiser assists its basic metals and mining industry clients by
providing the engineering and construction skills needed to maintain and
retrofit existing plants and replace aging production capacity with newer,
more efficient and more environmentally responsible facilities. The Company's
engineering and construction skills, as well as its access to process
technologies, have helped establish it as a worldwide leader in serving the
basic metals and mining industries, especially aluminum and steel. ICF Kaiser
is currently expanding its operations internationally, particularly
engineering and construction management services related to alumina production
from bauxite, aluminum smelting and other basic industry facilities.
 
BUSINESS STRATEGY
 
  The Company's business strategy is based primarily on providing its clients:
(i) full front-end capability; (ii) value-added services; (iii) access to
technology; and (iv) the benefits of the Company's strategic relationships.
 
  Full Front-end Capability. The Company's front-end skills include policy
analysis and consulting; scientific analysis and health/risk assessments;
facility siting and environmental assessments; remedial investigations and
feasibility studies; and engineering design. By possessing these skills, the
Company's involvement at the outset of any project places it in a position to
participate in any follow-on engineering and construction work.
 
  Value-added Services. The Company provides value-added services within those
markets that relate to environmental services through specialized
environmental knowledge that (i) helps clients understand environmental
threats and opportunities and alternative ways in which such threats can be
managed and opportunities capitalized on; (ii) allows creation of customized
solutions, including remedial design and remedial action, for the clients'
environmental problems; and (iii) combines problem identification, solution,
and implementation.
 
  Access to Technology. The Company has access to technologies that can assist
clients clean up existing waste sites, reduce waste generated by ongoing and
new production processes, reduce and monitor emissions, improve the quality of
finished products, assist in the production in the basic metal and mining
industries, and reduce costs. To increase its overall participation in
clients' projects, the Company continues to expand its access to leading
environmental and process technologies through various methods, including
licensing and joint ventures.
 
  Strategic Relationships. The Company has established business relationships
through joint ventures, marketing agreements, and direct equity investments
that extend its presence and reduce its business development risks. These
relationships are particularly important in the management of the Company's
international operations, and they help reduce the cost and risks associated
with the Company's entering new geographic regions.
 
BUSINESS GROUPS
 
  The Company is organized into three business groups: the Federal Programs
Group; the ICF Kaiser Engineers Group; and the Consulting Group.
 
                                      40
<PAGE>
 
 Federal Programs Group
 
  The Company derives a substantial portion of its revenues from contracts
with various agencies and departments of the Federal government. The Federal
Programs Group's major clients are the DOE and the DOD.
 
  U.S. Department of Energy. An important DOE mission has changed over the
years--from nuclear weapons production to environmental cleanup of former
nuclear weapons production sites. To help accomplish DOE's cleanup goals
pursuant to this new mission, the Company actively supports DOE at the
following facilities: Argonne National Laboratory, Idaho National Engineering
Laboratory, Lawrence Livermore National Laboratory, Los Alamos National
Laboratory, Mound Plant Site, Oak Ridge National Laboratory, two Sandia
National Laboratories, Hanford Site and Rocky Flats. The Company provides many
services at these facilities, including (i) conducting comprehensive
assessments related to environment, safety, and health; (ii) quality
assurance; (iii) security and safeguards; (iv) assessing, managing, and
remediating existing hazardous and solid wastes, mixed wastes, radioactive
materials, highly volatile chemical compounds, unidentified mixed wastes, and
exploded/unexploded munitions; and (v) architect, engineer, construction, and
site operations.
 
  In 1995, the Company, through Kaiser-Hill, won DOE's Performance Based
Integrating Management contract at Rocky Flats. Rocky Flats is a former DOE
nuclear weapons production facility. Under the five-year contract, Kaiser-Hill
oversees plutonium stabilization and storage, environmental restoration, waste
management, decontamination and decommissioning, site safety and security, and
construction activities of subcontractor companies. Under the performance-
based contract signed by Kaiser-Hill, the concept which was developed in the
DOE's 1994 Contract Reform Initiative, 85% of Kaiser-Hill's fees are based on
performance, while only 15% are fixed. Kaiser-Hill's contract commits it to
dealing with urgent risks first, and measurable results in the following
"urgent risk" areas determines its incentive fee: stabilize plutonium and
plutonium residues for specific time frames; consolidate plutonium in a single
building; and clean up and remove all high-risk "hot spot" contamination.
Finally, Kaiser-Hill is expected to reduce the number of employees at the site
by the end of the contract term.
 
  In August 1996, the Company was informed that the team of which it was a
member was unsuccessful in its bid for DOE's new management and integration
contract at the DOE's Hanford Site, Richland, Washington, where the Company
had worked since 1987. The Company's existing contract at Hanford effectively
was terminated by DOE on October 1, 1996. As a result, and based on the
Company's current assessment of the closeout of the Hanford contract,
management believes the impact on earnings will be material in the fourth
quarter of 1996, as well as future periods, unless replaced. In response to
the reduction and eventual elimination of the Hanford contract, in August 1996
the Company initiated a significant operational efficiency and cost savings
program, together with management changes, with the objective of minimizing
the long-term impact associated with the termination of the Hanford contract.
Termination of the Hanford contract is not expected to significantly impact
cash flows in the fourth quarter of fiscal year 1996 but may have a
significant impact after 1996 if the cost savings program is not successful.
 
  Effective October 1, 1996, ICF Kaiser Hanford Company acquired the Hanford
Site General Support Services Contract from the MACTEC Division of Management
Analysis Company of Golden, Colorado. The Company undertook the contract in
order to maintain a presence at Hanford and to further its strategic alliance
with MACTEC. Under the contract, ICF Kaiser provides administrative,
engineering, and technical support services for major DOE projects at the
Hanford Site, including tank waste remediation programs. In addition, the
Company will work closely with DOE to aid its strategic initiatives associated
with site cleanup and facility transition.
 
  U.S. Department of Defense. DOD estimates that its environmental expense
will be directed primarily to cleaning up hundreds of military bases with
thousands of contaminated sites. There is an urgent need to ensure that the
hazardous wastes present at these sites (often located near population
centers) do not pose a threat to the surrounding population, and, in
connection with the closure of many of the bases, there is an economic
incentive
 
                                      41
<PAGE>
 
to make sure that the environmental restoration enables the sites of the
former bases to be developed commercially by the private sector.
 
  DOD established the TERC program to clean up contaminated Army sites in a
streamlined and efficient manner by partnering with private contractors. A
TERC contract allows a single contractor to handle all aspects of remediation,
resulting in quicker cleanup, more effective project management, and better
coordination with federal and state regulators and the public. It also helps
to build a culture of cooperation among the USACE, the contractor, the
regulatory community, and the public.
 
  In September 1996, the Company signed a contract estimated at $260 million
to perform environmental restoration work at federal installations in the
South Pacific Division of the USACE. The TERC contract will be managed by the
Sacramento District, lasts for four years with two, three-year options, and
covers cleanup work at the Oakland (California) Army Base and at other Army
bases and federal installations in California, Arizona, Nevada, and Utah. The
Sacramento TERC was the second TERC awarded to ICF Kaiser. In August 1995, ICF
Kaiser won the largest hazardous, toxic, and radioactive waste contract ever
awarded by USACE, a $330 million TERC to remediate contaminated Army sites in
USACE's Baltimore District. ICF Kaiser's Baltimore TERC covers cleanup work at
Picatinny Arsenal in New Jersey, Aberdeen Proving Ground near Baltimore, and
other Army bases and federal installations in New York, New Jersey,
Pennsylvania, Delaware, Maryland, the District of Columbia, Virginia, and West
Virginia. The Baltimore TERC is for four years with two three-year options.
The contract is a cost reimbursement delivery order contract, and the fee
structure includes a combination of cost plus fixed fee, award fee, and
incentive fees.
 
  The Company also provides environmental services to USACE, Savannah
(Georgia) District, under several contracts, including a $50 million contract
to support the Corps' South Atlantic Division, as well as a $2 million
contract under which the company is designing contaminated groundwater
treatment systems at the Milan Army Ammunition Plant in Tennessee.
 
  Other Federal Government Work. Under a variety of smaller contracts, the
Company provides the Federal government with numerous other services. Under an
EPA contract awarded in 1995, the Company will continue to manage the EPA's
quality assurance laboratory in Las Vegas, Nevada, and provide the laboratory
with analytical support. The Company also supports the EPA's Superfund program
under Alternative Remedial Contracting Strategy ("ARCS") contracts for
remedial planning services. Architectural, engineering, and construction
management services for facilities and infrastructure (such as post offices,
court houses, and prisons) are provided to the U.S. Postal Service, Department
of Justice, and General Services Administration.
 
 ICF Kaisers Engineers Group
 
  ICF Kaiser assists clients in private industry by providing the engineering
and construction skills needed to maintain and retrofit existing plants and
replace aging production capacity with newer, more environmentally responsible
facilities. The Company has the engineering and construction skills, as well
as access to process technologies, needed to establish a leadership position
in serving the basic metals and mining industries, including aluminum, steel,
copper, and coal.
 
  All of ICF Kaiser's markets are global in nature. To capitalize on
international opportunities while minimizing its business development risks,
the Company has established international business relationships through joint
ventures, marketing agreements and direct equity investments. The Company has
projects underway in over 25 countries.
 
  Environmental Consulting and Engineering Services. Demand for the Company's
non-Federal environmental consulting and engineering services is driven by a
number of factors, including: the need to improve the quality of the
environment; environmental regulation and enforcement; and increased liability
associated with pollution-related injury and damage. Significant environmental
laws have been enacted in response to public concern over the environment, and
these laws and the implementing regulations affect nearly
 
                                      42
<PAGE>
 
every industrial activity. Increasingly strict Federal, state and local
government regulation has forced private industry and state and local agencies
to clean up contaminated sites, to bring production facilities into compliance
with current environmental regulations, and to minimize waste generation on an
ongoing basis. Although growth in this private-sector market is being hampered
by uncertainty over continuing Federal regulations, the Company generates new
business by increasing and expanding the services it sells to existing clients
and by targeting new markets for the Company's full-service capabilities.
 
  The Company's environmental services have progressed beyond study and
analysis to remediation. Following on its established market position in the
consulting and front-end analysis phase of environmental services, the Company
now offers alternative remediation approaches that may involve providing on-
site waste containment, on-site treatment, management of on-site/off-site
remediation, or waste removal. The Company also designs new processes (and
redesigns ongoing production processes) to minimize or eliminate the
generation of hazardous waste. Currently, the Company also provides site
investigations and feasibility studies, compliance planning and audits, risk
assessment, permitting, community relations services, and construction and
construction management. See "--Potential Environmental Liability."
 
  Industry Services. ICF Kaiser's engineering design, project management, and
construction services to the industrial market involve work with the steel,
aluminum, alumina, copper and other minerals and metals industries as well as
chemicals, petrochemicals, and refineries. In the coke, coal, and coal
chemicals area, ICF Kaiser's services have included inspection of coke plants
for environmental compliance, facility design and construction, and equipment
sales and services. The Company has provided services related to coal
cleaning, handling, and environmental controls. The Company recently announced
that it is negotiating to sell the PCI facility that it designed, built,
currently operates and jointly owns under a multiyear tolling agreement.
 
  The international market provides opportunities for the Company's industrial
services. The Company's largest industrial project will be a mini-mill project
for Nova Hut. Under a two-year contract signed in March 1996, the Company will
oversee the construction of the continuous slab caster portion of the mini-
mill as well as future production and environmental upgrades to Nova Hut's
existing integrated steel-making facilities. The Company will provide project
management, engineering, procurement, construction management, start-up,
commissioning, and training services. This initial phase of the mini-mill
project, which is scheduled to initiate production in June 1998, is part of a
two-phase endeavor in which the second phase will provide Nova Hut with a new
rolling mill with the capability of producing one million metric tons per year
of hot rolled steel product. The Company is currently negotiating a contract
with Nova Hut for the second phase of the mini-mill project. The Company
expects earnings from the next phase to be material to the Company's operating
results. Management expects to complete negotiations on this contract in the
first quarter of 1997, although there can be no assurance with respect
thereto. The Company also is assisting the International Finance Corporation
in securing the financing for the next phase of the mini-mill project.
 
  Infrastructure Services. The Company also is helping rebuild the
infrastructure of roads, highways, transit systems, harbors, airports,
facilities, and buildings in domestic and international markets. Budget
constraints at the Federal, state, and local government levels have hindered
domestic infrastructure market growth, but the Company remains active in major
U.S. metropolitan areas: Chicago (light rail transit system); Seattle (light
rail project); San Francisco (commuter rail line extension); Atlanta (general
engineering consulting services to the Metropolitan Atlanta Rapid Transit
Authority); and Miami (Intermodal Transit Center, a project that will tie
together air, light/heavy rail, buses, highway systems, and parking
facilities).
 
  In the international infrastructure market, the Company's large-scale
construction infrastructure skills are at work in Portugal where the Company,
as part of a joint venture, provides project and construction management
services for the modification and reconstruction of the main rail link between
the cities of Lisbon and Oporto. The Company also provides program management
services for the overhaul and upgrade of Portugal's main intercity freight and
passenger rail lines. Those skills also are at work in the Philippines where
the Company, as part of a joint venture, provides front-to-back-end services
for a light rail transit line in Manila. In Brazil, the Company is developing
the plan to remediate and clean up Guanabara Bay.
 
                                      43
<PAGE>
 
  The major ports of many of the world's cities have serious water pollution
problems, and ICF Kaiser is helping to improve the condition of many harbors
and waterways. In its largest harbor project, the Company continues as the
construction manager of the cleanup of Boston Harbor, one of the largest
environmental projects in the country, under a contract extension that runs
through 1998. Since the inception of the project in 1988, the Company has
served as its construction manager, and currently manages construction
workers, engineers, architects, and support personnel working to construct a
wastewater treatment plant on Deer Island in Boston Harbor.
 
  International Services. ICF Kaiser provides engineering, construction
management, and consulting services through companies managed and staffed by
local professionals in Australia, Taiwan, the Philippines, Mexico, Brazil,
Portugal, France, England, Russia, and the Czech Republic, as well as project
offices throughout the world. International projects include design
engineering for the expansion of a major alumina refinery in Western
Australia; and environmental remediation of hydrocarbon contamination in soil
and groundwater in France and Mexico.
 
 Consulting Group
 
  The Consulting Group serves customers in domestic and international markets,
including both public- and private-sector organizations. Among its major
customers are U.S. government agencies, especially the EPA; U.S. private
sector organizations, particularly major energy producers such as utilities
and oil companies; and governments and businesses around the world, as well as
various multinational banks, development organizations, and treaty
organizations. The Consulting Group draws upon the talents of its multi-
disciplinary professional staff to support customers within four primary lines
of business.
 
  Environmental Consulting Services. This line of business assists customers
in developing plans and policies, evaluating options for managing
environmental responsibilities in the most cost-effective manner, and
identifying and employing the best available technologies and practices. Life-
cycle management strategies are emphasized. The group has special expertise in
such areas as industrial and municipal waste management, air pollution
control, chemical accident prevention, and ground-water and drinking water
management. The Consulting Group also provides technical and regulatory
support to the EPA's Office of Solid Waste, focusing on human health and
ecological risk assessment and waste characterization.
 
  Global environmental issues are also a particular area of focus within the
Consulting Group. Working with U.S. and international organizations that fund
global environmental work and with numerous private sector organizations, the
Consulting Group has conducted projects in over thirty countries and has been
actively involved in supporting international environmental treaties. The
group has achieved great success in implementing technology transfer programs
through the creation of effective public-private partnerships. Working on
global change issues for the EPA for 14 years, the Company supports the EPA's
Global Change Division, providing services related to the reduction of methane
and other greenhouse gases.
 
  In September 1996, the Consulting Group announced that it had signed a five-
year contract, potentially valued at more than $60 million, to provide
technical analysis and implementation support for EPA's Green Lights and
ENERGY STAR programs. The Consulting Group has worked on EPA's voluntary
public-private partnership programs on energy efficiency and methane reduction
since their inception in 1990.
 
  In-career Education and Training Programs. Consulting services in this line
of business range in subject matter from highly technical areas to broader,
skill-based and management-oriented training. The Consulting Group's expertise
in the development and delivery of workplace training, combined with expert
knowledge in a wide variety of technologies and programmatic areas, enables it
to provide high impact training that is specifically tailored to the needs of
each customer organization. Environmental management programs cover
regulation, technology, information reporting, emergency response, and
pollution prevention.

  Information Management Programs. The Company assists clients in developing
decision support systems that facilitate the collection and use of information
to track performance, identify opportunities and improve decision making. The
group offers a number of sophisticated simulation models and proprietary
applications. By combining consulting expertise with information technology
skills, the group helps its customers deal with the unique challenges of their
business environment.
 
  Energy and Natural Resource Management Services. This line of business
supports the development of corporate and technical plans for managing power
resources and energy projects, provides economic assessments of short- and
long-term market conditions for various fuels, and serves as an expert
foundation in litigation and regulatory proceedings. The Consulting Group
assists its customers in identifying market opportunities, commercializing new
technologies, and developing public policy. Its contributions involve linking
an in-depth understanding of the energy markets with an ongoing involvement
with energy technology.
 
COMPETITION AND CONTRACT AWARD PROCESS
 
  The market for the Company's services is highly competitive. The Company and
its subsidiaries compete with many other environmental consulting, engineering
and construction firms ranging from small firms to large multinational firms
having substantially greater financial, management, and marketing resources
than the Company. Other competitive factors include quality of services,
technical qualifications, reputation, geographic presence, price, and the
availability of key professional personnel.
 
  Competition for private-sector work generally is based on several factors,
including quality of work, reputation, price, and marketing approach. The
Company'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.
 
  Most of the Company'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
Proposal (RFP) that delineates the size and scope of the proposed contract.
Proposals are evaluated by the government on the basis of technical merit (for
example, response to mandatory solicitation provisions, corporate and
personnel qualifications, and experience) and cost. The Company believes that
its experience and ongoing work strengthen its technical qualifications and,
thereby, enhance its ability to compete successfully for future government
work.
 
  In both the private and public sectors, the Company, acting either as a
prime contractor or as a subcontractor, may join with other firms to form a
team that competes for a single contract or submits a single proposal. Because
a team of firms almost always can offer a stronger set of qualifications than
any firm standing alone, these teaming arrangements often are very important
to the success of a particular competition or proposal. The Company maintains
a large network of business relationships with other companies and has drawn
repeatedly upon these relationships to form winning teams.
 
  The Company's subsidiaries operate 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, the
Company'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 the Company is paid at a specified fixed hourly rate for
direct labor hours worked. Under Fixed Price contracts, the Company is paid a
predetermined amount for all services provided as detailed in the design and
performance specifications agreed to at the project's inception.
 
CUSTOMERS
 
  The Company's clients include DOE, EPA, and DOD; major corporations in the
energy, transportation, chemical, steel, aluminum, mining, and manufacturing
industries; utilities; and a variety of state and local
 
                                      45
<PAGE>
 
government agencies throughout the United States. A substantial portion of the
Company's work is repeat business from existing clients. In many cases, the
Company has worked for the same client for many years, providing different
services at different times. DOE accounted for approximately 68% of the
Company's consolidated gross revenue for the ten months ended December 31,
1995; EPA accounted for another approximately 6%; and DOD and other Federal
agencies collectively accounted for another approximately 4%. The Federal
government accounted for approximately 73% of the Company's consolidated gross
revenue in fiscal year 1995 and 65% in fiscal year 1994.
 
  The Company's international clients include both private firms and foreign
government agencies in such countries as Australia, France, Portugal, and
Taiwan. For the ten months ended December 31, 1995, foreign operations
accounted for approximately 4.7% of the Company's consolidated gross revenue.
For information concerning gross revenue, operating income, and identifiable
assets of the Company's business by geographic area, see Note O to the
Consolidated Financial Statements for the ten months ended December 31, 1995.
 
BACKLOG
 
  Backlog refers to the aggregate amount of gross contract revenue remaining
to be earned pursuant to signed contracts extending beyond one year. At
September 30, 1996, the Company's contract backlog was approximately $3.9
billion in gross revenue, down from approximately $4.4 billion in gross
revenue at December 31, 1995. The Company expects that approximately 6.4% of
the total backlog at September 30, 1996, will be worked off during the last
fiscal quarter of fiscal year 1996. Because of the nature of its contracts,
the Company is unable to calculate the amount or timing of service revenue
that might be earned pursuant to these contracts. The Rocky Flats contract
with Kaiser-Hill represents approximately $2.3 billion of the Company's $3.9
billion backlog at September 30, 1996. The Company believes that backlog is
not a predictor of future gross or service revenue.
 
  Differences in contracting practices between the public and private sectors
result in the Company's backlog being weighted heavily toward contracts
associated with agencies of the Federal government. Backlog under contracts
with agencies of the Federal government that extend beyond the government's
current fiscal year includes the full contract amount, including in many cases
amounts anticipated to be earned in option periods and certain performance
fees, even though annual funding of the amounts under such contracts generally
must be appropriated by Congress before the agency may expend funds during any
year under such contracts. In addition, the agency must allocate the
appropriated funds to these specific contracts and thereafter authorize work
or task orders to be performed under these specific contracts. Such
authorizations are generally for periods considerably shorter than the
duration of the work the Company expects to perform under a particular
contract and generally cover only a percentage of the contract revenue.
Because of these factors, the amount of Federal government contract backlog
for which funds have been appropriated and allocated, and task orders issued,
at any given date is a substantially smaller amount than the total Federal
government contract backlog as of that date. In the event that option periods
under any given contract are not exercised or funds are not appropriated,
allocated or authorized to be spent under any given contract, the amount of
backlog attributable to that contract would not result in revenue to the
Company. All contracts and subcontracts with agencies of the Federal
government are subject to termination, reduction, or modification at any time
at the discretion of the government agency.
 
ENVIRONMENTAL REGULATION
 
  Significant environmental laws have been enacted in response to public
concern over the environment. These laws and the implementing regulations
affect nearly every industrial activity. Efforts to comply with the
requirements of these laws have increased demand for the Company's services.
The principal Federal legislation having the most significant effect on the
Company's business includes the following:
 
  The Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA"). CERCLA, as amended by the Superfund Amendments and Reauthorization
Act, established the Superfund program to clean
 
                                      46
<PAGE>
 
up hazardous waste sites and provides for penalties and punitive damages for
noncompliance with EPA orders. Superfund may impose strict liability (joint
and several as well as individual) on certain hazardous substance waste
owners, operators, disposal "arrangers," transporters, and disposal facility
owners and operators (Potentially Responsible Parties or PRPs) for the costs
of removal or remedial action; for other necessary response costs and damages
for injury, destruction, or loss of natural resources; and for the cost of
health effects study. Under certain circumstances Federal funds may be used to
pay for the cleanup.
 
  The Resource Conservation and Recovery Act ("RCRA"). RCRA, as amended by the
Hazardous and Solid Waste Amendments of 1984, provides a comprehensive scheme
for the regulation of hazardous waste from the time of generation to its
ultimate disposal (and sometimes thereafter), as well as the regulation of
persons engaged in the treatment, storage, and disposal of hazardous waste.
The RCRA scheme includes both a permitting and a manifest tracking system and
detailed regulations on the handling, treatment, transportation, storage, and
disposal of hazardous and solid waste. Regulations have been issued pursuant
to RCRA in the following areas (among others) of importance to the Company:
permitting; remediation of releases associated with underground storage tanks;
municipal solid waste disposal; waste minimization; corrective action; and
treatment, transportation, and disposal of hazardous waste. HSWA has increased
the number of hazardous waste generators subject to RCRA. HSWA also imposes
land disposal restrictions/bans on certain listed and characteristic hazardous
wastes that do not meet specified treatment standards.
 
  The Clean Air Act. Under the Clean Air Act, as amended in 1970 and 1990, EPA
is empowered to establish and enforce National Ambient Air Quality Standards,
National Emission Standards for Hazardous Air Pollutants, and limits on the
emissions of various pollutants from specific types of facilities. The 1990
amendments require certain sources emitting an air pollutant regulated under
the Clean Air Act to obtain an operating permit, which includes enforceable
emissions limitations and compliance schedules. The Clean Air Act also
addresses substantial expanded regulation of vehicle emissions, hazardous air
pollutant emissions, stratospheric ozone protection, acid rain minimization
(through the use of limitations on sulfur dioxide and nitrogen oxide
emissions) and related enforcement issues. The use of "marketable allowances"
to establish limits on total emissions while maintaining maximum market
flexibility reflects a shift in environmental policy from command and control
management to a more flexible approach.
 
  Other Statutes. Under the Safe Drinking Water Act of 1974, as amended, EPA
is empowered to set drinking water standards for community water supply
systems and to control subsurface injection of waste. The Clean Water Act, as
amended in 1972 and 1990, established a system of standards, permits, and
enforcement procedures for the discharge of pollutants to surface water from
industrial, municipal and other wastewater sources. Under the Ocean Dumping
Act of 1972, as amended in 1988, regulatory revisions to the Clean Water Act
were made to eliminate ocean dumping of sludge. The Toxic Substance Control
Act of 1976 establishes requirements for identifying and controlling toxic
chemical hazards to human health and the environment. The Federal Insecticide,
Fungicide, and Rodenticide Act of 1947, as amended in 1988, focuses on the
health-based risk of pesticides and requires the registration of all
pesticides, with a heavy emphasis on scientific data and risk assessment. The
Oil Pollution Act of 1990 covers the discharge of oil and hazardous substances
into navigable waters, adjoining shorelines or the exclusive economic zone of
the United States.
 
POTENTIAL ENVIRONMENTAL LIABILITY
 
  The assessment, analysis, remediation, handling, management, and disposal of
hazardous substances necessarily involve significant risks, including the
possibility of damages or personal injuries caused by the escape of hazardous
materials into the environment, and the possibility of fines, penalties or
other regulatory action. These risks include potentially large civil and
criminal liabilities for violations of environmental laws and regulations, and
liabilities to customers and to third parties for damages arising from
performing services for clients.
 
 Potential Liabilities Arising Out of Environmental Laws and Regulations
 
  All facets of the Company's business are conducted in the context of a
rapidly developing and changing statutory and regulatory framework. The
Company's operations and services are affected by and subject to
 
                                      47
<PAGE>
 
regulation by a number of Federal agencies, including EPA, the Nuclear
Regulatory Commission and the Occupational Safety and Health Administration,
as well as applicable state and local regulatory agencies.
 
  As discussed above, CERCLA addresses cleanup of sites at which there has
been a release or threatened release of hazardous substances into the
environment. Increasingly, there are efforts to expand the reach of CERCLA to
make environmental contractors responsible for cleanup costs by claiming that
environmental contractors are owners or operators of hazardous waste
facilities or that they arranged for treatment, transportation, or disposal of
hazardous substances. Several recent court decisions have accepted these
claims. Should the Company be held responsible under CERCLA for damages caused
while performing services or otherwise, it may be forced to bear such
liability by itself, notwithstanding the potential availability of
contribution or indemnity from other parties.
 
  RCRA, also discussed above, governs hazardous waste generation, treatment,
transportation, storage, and disposal. RCRA, or EPA-approved state programs at
least as stringent, govern waste handling activities involving wastes
classified as "hazardous." Substantial fees and penalties may be imposed under
RCRA and similar state statutes for any violation of such statutes and the
regulations thereunder.
 
 Potential Liabilities Involving Clients and Third Parties
 
  In performing services for its clients, the Company 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.
 
  Environmental contractors, in connection with work performed for clients,
potentially face liabilities to third parties from various claims, including
claims for property damage or personal injury stemming from a release of
hazardous substances or otherwise. Claims for damage to third parties could
arise in a number of ways, including through a sudden and accidental release
or discharge of contaminants or pollutants during the performance of services;
through the inability, despite reasonable care, of a remedial plan to contain
or correct an ongoing seepage or release of pollutants; through the
inadvertent exacerbation of an existing contamination problem; or through
reliance on reports or recommendations prepared by the Company. Personal
injury claims could arise contemporaneously with performance of the work or
long after completion of the project as a result of alleged exposure to toxic
or hazardous substances. In addition, increasing numbers of claimants assert
that companies performing environmental remediation should be adjudged
strictly liable, i.e., liable for damages even though its services were
performed using reasonable care, on the grounds that such services involved
"abnormally dangerous activities."
 
  Clients frequently attempt to shift various of the liabilities arising out
of remediation of their own environmental problems to contractors through
contractual indemnities. Such provisions seek to require the Company to assume
liabilities for damage or personal injury to third parties and property and
for environmental fines and penalties. The Company has endeavored to protect
itself from potential liabilities resulting from pollution or environmental
damage by obtaining indemnification from its private-sector clients and
intends to continue this practice in the future. Under most of these
contracts, the Company has been successful in obtaining such indemnification;
however, such indemnification generally is not available if such liabilities
arise as a result of breaches by the Company of specified standards of care or
if the indemnifying party has insufficient assets to cover the liability. The
Company has a wholly owned subsidiary, ICF Kaiser Remediation Company, through
which it intends to increase its remediation activities performed for public-
and private-sector clients. The Company will continue its efforts to minimize
the risks and potential liability associated with its remediation activities
by performing all remediation contracts in a professional manner and by
carefully reviewing any and all remediation contracts it signs in an effort to
ensure that its environmental clients accept responsibility for their own
environmental problems.
 
  For EPA contracts involving field services in connection with Superfund
response actions, the Company is eligible for indemnification under Section
119 of CERCLA, for pollution and environmental damage liability
 
                                      48
<PAGE>
 
resulting from release or threatened release of hazardous substances. Some of
the Company's clients (including private clients, DOE, and DOD) are
Potentially Responsible Parties (PRPs) under CERCLA. Under the Company's
contracts with these PRPs, the Company has the right to seek contribution from
these PRPs for liability imposed on the Company in connection with its work at
these clients' CERCLA sites and, with respect to Federal government clients,
generally qualifies for the limitations on liabilities under CERCLA Section
119(a). In addition, in connection with contracts involving field services at
DOE weapons facilities, including the DOE's Hanford site, the Company is
indemnified under the Price-Anderson Act, as amended, against liability claims
arising out of contractual activities involving a nuclear incident. Recently,
EPA has constricted significantly the circumstances under which it will
indemnify its contractors against liabilities incurred in connection with
CERCLA projects. There are other proposals both in Congress and at the
regulatory agencies to further restrict indemnification of contractors from
third-party claims.
 
  As discussed above, Kaiser-Hill signed a Performance Based Integrating
Management contract with DOE. The terms of that contract provide that Kaiser-
Hill shall not be held responsible for, and DOE shall pay 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 shall be
responsible, but only for the incremental liability, expense, or remediation
caused by Kaiser-Hill.
 
  The Kaiser-Hill contract further provides that Kaiser-Hill shall be
reimbursed for the reasonable cost of bonds and insurance allocable to the
Rocky Flats contract and for liabilities (and expenses incidental to such
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.
 
  In connection with its services to its environmental, infrastructure, and
industrial clients, the Company works closely with Federal and state
government environmental compliance agencies, and occasionally contests the
conclusions those agencies reach regarding the Company's compliance with
permits and related regulations. To date, the Company never has paid a fine in
a material amount or had material liability imposed on it for pollution or
environmental damage in connection with its services. However, there can be no
assurance that the Company will not have substantial liability imposed on it
for any such damage in the future.
 
INSURANCE
 
  The Company has a comprehensive risk management and insurance program that
provides a structured approach to protecting the Company. Included in this
program are coverages for general, automobile, pollution impairment, and
professional liability; for workers' compensation; and for employer and
property liability. The Company believes that the insurance it maintains,
including self-insurance, is in such amounts and protects against such risks
as is customarily maintained by similar businesses operating in comparable
markets. At this time, the Company expects to continue to be able to obtain
general, automobile, and professional liability; workers' compensation; and
employers and property 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 the Company.
 
  Consistent with industry experience and trends, the Company has obtained
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 the Company's environmental activities, if
successful and of sufficient magnitude, could have a material adverse effect
on the Company.

REGULATION
 
  The Company has a substantial number of cost-reimbursement contracts with
the U.S. government, the costs of which are subject to audit by the U.S.
government. As a result of pending audits relating to fiscal years 1986
forward, the government has asserted, among other things, that certain costs
claimed as reimbursable under government contracts either were not allowable
or not allocated in accordance with federal procurement regulations. The
Company is actively working with the government to resolve these issues. The
Company has provided for the potential effect of disallowed costs for the
periods currently under audit and for periods not yet audited, although the
amounts at issue have not been quantified by the government or the Company.
This provision will be reviewed periodically as discussions with the
government progress. Based on the information currently available, management
believes the potential effects of these pending audits will not have a
material adverse effect on the Company's financial position, results of
operations, or cash flows.
 
  The Company 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. The Company 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 the Company by these agencies. Management
does not believe that there will be any material adverse effect on the
Company's financial position, operations, or cashflows as a result of these
investigations.
 
  Federal agencies that are the Company's regular customers (including DOE,
EPA, and DOD) have formal policies against awarding contracts that would
present actual or potential conflicts of interest with other activities of the
contractor. Because the Company provides a broad range of services in
environmental and related fields for the Federal government, state
governments, and private customers, there can be no assurance that government
conflict-of-interest policies will not restrict the Company's ability to
pursue business in the future.
 
  Because some of the Company's subsidiaries provide the Federal government
with nuclear energy and defense-related services, these subsidiaries and a
substantial number of their employees are required to have and maintain
security clearances from the Federal government. These subsidiaries and their
employees have been able to obtain these security clearances in the past, and
the Company has no reason to believe that there would be any problems in this
area in the future. However, there can be no assurance that the required
security clearances will be obtained and maintained in the future. Because of
its nuclear energy and defense-related services, the Company is subject to
foreign ownership, control, and influence ("FOCI") regulations imposed by the
Federal government and designed to prevent the release of classified
information to contractors who are under foreign control or influence. Under
these regulations, FOCI concerns may arise as a result of a variety of
factors, including foreign ownership of substantial percentages of equity
securities or debt, a high percentage of foreign revenue, and the number of
directors and officers who are not U.S. citizens. Subsidiaries of the Company
with facility security clearances or sensitive DOE contracts file reports with
DOD and DOE with respect to events and changes that affect the potential for
FOCI. The Company has implemented procedures designed to insulate such
subsidiaries from any FOCI that might affect the Company. There can be no
assurance that such measures will prevent FOCI policies from affecting the
ability of the Company's subsidiaries to secure and maintain certain types of
DOD and DOE contracts.
 
EMPLOYEES
 
  As of November 30, 1996, ICF Kaiser employed 5,176 people, and the Company
believes that its relations with its employees are good. Of the total
employees, 2,005 persons are employed at Kaiser-Hill's Rocky Flats site in
Colorado. A total of 1,361 of the Rocky Flats personnel are represented by the
United Steelworkers of America, Local 8031. The Company believes that its
relations with the unions are good.
 
PROPERTIES
 
  All of the Company's operations are conducted either in leased facilities or
in facilities provided by the Federal government or other clients. As of
September 30, 1996, the Company leased an aggregate of
 
                                      50
<PAGE>
 
approximately one million square feet of space. The terms of these leases
range from month-to-month to 15 years, and some may be renewed for additional
periods. Some of the space leased by the Company has been subleased to other
entities under subleases expiring from 1996 to 2000.

LEGAL AND REGULATORY PROCEEDINGS
 
  The Company and its subsidiaries are involved in a number of lawsuits and
government regulatory proceedings arising in the ordinary course of its
business or arising in connection with the disposition or acquisition of
certain businesses and investments. The Company believes that any ultimate
liability resulting therefrom will not have a material adverse effect on its
financial position, operations, or cash flows.
 
  In the course of the Company's normal business activities, various claims or
charges have been asserted and litigation commenced against the Company
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 the Company in such litigation.
 
  The Company 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. The Company 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 the Company by these agencies. Management
does not believe there will be any material adverse effect on the Company's
financial position, operations, or cashflows as a result of these
investigations.
 
  The Company has a substantial number of cost-reimbursement contracts with
the U.S. government, the costs of which are subject to audit by the U.S.
government. As a result of pending audits relating to fiscal years 1986
forward, the government has asserted, among other things, that certain costs
claimed as reimbursable under government contracts either were not allowable
or not allocated in accordance with federal procurement regulations. The
Company is actively working with the government to resolve these issues.
Management has provided for the potential effect of disallowed costs for the
periods currently under audit and for periods not yet audited, although the
amounts at issue have not been quantified by the government or the Company.
This provision will be reviewed periodically as discussions with the

SENIOR EXECUTIVE OFFICERS SEVERANCE PLAN
 
  In April 1994 the Compensation Committee of the Board of Directors approved
the adoption of the Company's Senior Executive Officers Severance Plan (the
"SEOSP"). In December 1994, the SEOSP was amended to clarify (a) that once an
officer becomes a participant in the SEOSP, he or she will continue to be
eligible for SEOSP benefits throughout his or her employment by the Company
and (b) that the SEOSP is intended to set a minimum severance benefit for the
participant. If a participant is entitled to a greater benefit under his or
her employment agreement with the Company, then such arrangement prevails over
the lower SEOSP benefit.
 
  The eligible participants in the SEOSP are the Chief Executive Officer, the
President, the Chief Operating Officer, the Chief Financial Officer, the
Treasurer, the General Counsel, the Senior Vice President and Director of
Human Resources, and any Executive Vice President and other officers of rank
equivalent to Executive Vice President as designated by the Compensation
Committee. As of November 30, 1996, there were eight persons whose severance
payments are governed by the SEOSP.
 
  A participant is eligible to receive severance payments if the Company
terminates his or her employment without "cause" or if the participant
terminates his or her employment for "good reason." "Cause" and "good reason"
are defined in the SEOSP. Severance benefits equal to three months of average
salary will be paid if the participant's length of employment is three years
or less; severance benefits equal to one month of average salary for each year
of service (up to a maximum of 18 months) will be paid if a participant's
length of employment is four or more years. Average salary is defined in the
SEOSP as the participant's average monthly gross salary excluding all bonus
for the nine months prior to employment termination. Severance benefits may be
paid under the SEOSP in two installments or, with the approval of the
Compensation Committee, in a lump sum. The SEOSP provides that severance pay
will not be considered compensation for purposes of the Retirement Plan or the
Section 401(k) Plan; severance pay will not increase Years of Service for
those Plans' purposes. No severance benefits have been paid under the Plan
since the SEOSP was adopted.

vesting in 37,500 increments over four years beginning May 15, 1995) at fair

non-competition period following voluntary or "for cause" employment
termination. The Company's transactions with Mr. Edwards are described in the

Offering Memorandum.
 
  Stephen W. Kahane. Effective March 1, 1994, the Company entered into a
three-year employment agreement with Dr. Kahane for his services as an
Executive Vice President and as Group President of the Company's re-named
Federal Programs Group. In addition to delineating Dr. Kahane's areas of
responsibility and reporting line, the agreement provides for his annual
salary; annual bonus compensation to be determined by the Compensation

the agreement provides for his salary, bonuses, options, other employee
benefits, and interest-free loans to facilitate the sale of Mr. Rapp's
California residence and the purchase of a new residence near the Company's
Virginia headquarters. As of September 30, 1996, two of these loans had been
forgiven under the terms of the employment agreement because the proceeds from
the sale of Mr. Rapp's California residence were less than anticipated. The
third loan (dated January 20, 1994) has a balance of $300,000 as of September
30, 1996, is secured by Mr. Rapp's Virginia residence, and is due and payable
in full on the earliest to occur of (a) January 20, 1999, (b) termination of
Mr. Rapp's employment by the Company, (c) provision of reasonably satisfactory
substitute collateral, or (d) the occurrence of a defined event of default.
The largest aggregate amount of Mr. Rapp's indebtedness to the Company
outstanding at any time since March 1, 1994 was $648,546. As of November 8,
1996, Mr. Rapp is an employee, but no longer an executive officer, of the
Company.
 
  Marc Tipermas. Effective March 1, 1994, the Company entered into a three-
year employment agreement with Dr. Tipermas for his services as Executive Vice
President and Director of Corporate Development of the Company. Dr. Tipermas
also is a director of the Company. In addition to delineating Dr. Tipermas'
areas of responsibility and reporting line, the agreement provides for his
salary; annual bonus compensation to be determined by the Compensation
Committee of the Company's Board of Directors (in amounts specified in the
agreement); severance payments as provided under the Company's Senior
Executive Officers Severance Plan; eligibility under the Company's employee
benefit plans; cancellation of 60,000 existing options to purchase the

AGREEMENTS AND TRANSACTIONS WITH OTHER EXECUTIVE OFFICERS
 
  Michael K. Goldman. Effective February 28, 1994, the Company and Mr. Goldman
agreed to terminate Mr. Goldman's Amended Executive and Compensation
Agreements originally signed in December 1990. Effective March 1, 1994, the
Company and Mr. Goldman entered into an employment arrangement under which Mr.
Goldman (a) serves as an employee of the Company at a specified annual salary;
(b) received the $50,000 special cash payment provided for in his December
1990 Compensation Agreement; and (c) was designated, with certain specified
restrictions, as a participant in the Senior Executive Officers Severance
Plan. In addition, all then-unvested options previously granted to Mr. Goldman
vested as of March 1, 1994. The Company and Mr. Goldman also agreed to amend
the terms of Mr. Goldman's outstanding loan with the Company as follows: the
principal shall be due upon demand by the Company but no later than February
28, 1999; interest from May 16, 1994, shall accrue on the outstanding
principal at 6% per annum; and payment of interest will be deferred until such
time as the principal is due. No interest shall accrue or be payable on such
deferred interest. Mr. Goldman's loan is secured by 33,134 shares of the
Company's Common Stock and is non-recourse to Mr. Goldman. The Company and Mr.
Goldman agreed that if the value of the pledged stock is less than the then-
outstanding amount of principal and interest at the time of loan repayment
demand (or February 28, 1999, at the latest), then the Company will retire the
principal and interest by considering the pledged shares to have been sold
back to the Company (within the constraints set forth in the Company's debt
and equity instruments). The outstanding balance as of September 30, 1996, was
$191,647, plus accrued interest. The largest aggregate amount of Mr. Goldman's
indebtedness to the Company outstanding at any time since March 1, 1995 was
$191,647.

(a) Except as noted below, all information in the above table is as of
    December 31, 1996. To calculate the voting percentage, it was assumed that
    the individual or entity exercised all of his/her/its exercisable options,
    but that no other individuals or entities exercised theirs. A person is
    deemed to be a beneficial owner of the Company's stock if that person has
    voting or investment power (or voting and investment powers) over any
    shares of capital stock or has the right to acquire such shares within 60
    days from December 30, 1996. With respect to the total number of shares

                      DESCRIPTION OF THE CREDIT FACILITY
 
  Effective on May 7, 1996, the Company entered into a revolving credit and
letter of credit facility (the "Credit Facility"), with a syndicate of three
banks (the "Banks"). The agent for the Banks (the "Agent") is CoreStates Bank,
N.A. Capitalized terms and acronyms used but not defined in this description
of the Credit Facility have the meanings assigned to them in the agreement
governing the Credit Facility. Effective December 17, 1996, the Company and
the Banks signed an Amendment to the Credit Facility (the "Amendment") that
approved the Disposition of PCI, provided for a temporary Over Advance
Provision (as defined in the Amendment) and permitted the net proceeds from
the issuance of the Old Notes and borrowings under the Over Advance Provision
to be used to redeem the Series 2D Senior Preferred Stock. Material terms of
the Credit Facility and the Amendment are summarized below.
 
  Borrowing Availability and Termination Date. Under the Credit Facility,
loans may be made to the Company and letters of credit may be issued at the
request of the Company for an aggregate amount of the lesser of (i) $40
million or (ii) the Borrowing Base (85% of Eligible Billed Accounts Receivable
and Certain Unbilled Accounts Receivable up to a maximum of $10 million). If
the Company sells assets other than in the ordinary course of business while
the Credit Facility is in effect, the borrowing availability will be reduced
by the net cash proceeds from each sale; however, there is no mandatory
reduction for the first approximately $5 million in aggregate net cash
proceeds. The Credit Facility terminates on June 30, 1998. Under the
Amendment, the Credit Facility has been increased to $45 million until March
31, 1997 and excludes the Disposition of PCI from the mandatory facility
reduction requirement following certain asset sales.
 
  Interest. The Credit Facility and the Amendment contain LIBOR and Base Rate
options, each with applicable margins determined from time to time based on
the ratio of the Company's EBITDA to Consolidated Interest Expense, payable
monthly. Under the Credit Facility and the Amendment, EBITDA is defined, for
any period, as Consolidated Net Income plus the sum of (a) Consolidated
Interest Expense, (b) income tax expense, (c) depreciation expense, (d)
amortization expense, (e) extraordinary or unusual losses or other losses not
incurred in the ordinary course of business included in the calculation of net
income, (f) any non-cash charge against net income required to be recognized
in connection with the issuance of capital stock to employees (whether upon
lapse of vesting restrictions, exercise of employee options or otherwise) and
(g) any non-cash charge against net income required to be recognized in
connection with employee benefit plans less extraordinary or unusual gains or
other gains not incurred in the ordinary course of business included in the
calculation of net income, in each case to the extent such items are taken
into account in determining Consolidated Net Income.
 
  Fee. The Company pays certain fees and commissions to the Banks, including a
commitment fee of 5/8% per annum on the unused portion of the Credit Facility.
Outstanding letters of credit bear a fee equal to the LIBOR applicable margin
in effect over the period, payable quarterly. The Company paid certain fees
and commissions for the Amendment.
 
  Subsidiary Guarantee. Certain Subsidiaries of the Company including the four
Subsidiary Guarantors under the Indentures (the "Credit Facility Subsidiary
Guarantors") entered into a joint and several guarantee of the Company's
payment obligations under the Credit Facility. Each of the Credit Facility
Subsidiary Guarantors also agreed to a number of covenants in favor of the
Agent, including covenants (each with specified exceptions) (i) not to create,
incur or permit to exist any Lien on its Collateral, (ii) not to sell,
transfer, lease, or otherwise dispose of any of its Collateral, (iii) not to
amend, modify, terminate or waive any provision of any agreement giving rise
to an Account in a manner that could have a materially adverse effect upon the
value of the Account as Collateral, and (iv) not to grant discounts,
compromises, or extensions of Accounts except in the ordinary course of
business.
 
  Collateral. To secure the payment and the punctual performance of all of the
Obligations under the Credit Facility, the Company and each of the Credit
Facility Subsidiary Guarantors granted to the Banks a general continuing lien
upon and security interest in all the Collateral. The Collateral is defined as
including all now-
 
                                      64
<PAGE>
 
existing or hereafter acquired or arising (i) Accounts, (ii) General
Intangibles, Chattel Paper and Instruments derived from or related to any
Accounts, (iii) guarantees of any Accounts and all other security held for the
payment or satisfaction thereof, (iv) goods or services the sale or lease of
which gave rise to any Account, including returned goods, (v) the balance of
any deposit, agency or other account with any Bank, (vi) Discounted Treasuries
delivered by the Company or the Credit Facility Subsidiary Guarantors to the
Agent pursuant to the Credit Facility and (vii) books, records and other
property at any time evidencing or related to the foregoing, together with all
products and Proceeds (including insurance Proceeds) of any of the foregoing.
Under the Amendment, the Collateral also includes all intangible assets of the
Company. The Company has pledged all of the stock of certain of its domestic
subsidiaries and 65% of the stock of certain foreign subsidiaries as further
security under the Credit Facility.
 
  Financial Covenants. The Credit Facility contains financial covenants that
require the Company to maintain certain financial ratios above or below
specified limits, including, but not limited to, those described below. The
Company has agreed that it will not permit the ratios of (i) EBITDA less
Capital Expenditures plus Consolidated Lease Expenses to Consolidated Fixed
Charges (the "Fixed Charge Coverage Ratio") and (ii) EBITDA to Consolidated
Interest Expense (the "Interest Coverage Ratio"), computed on a consolidated,
rolling four quarters basis to be less than those set forth below:

  Under the Amendment, the Fixed Charge Coverage Ratio from the date of the
Amendment to September 30, 1997 has been reduced to 1.05:1.00 and the Interest
Coverage Ratio has been reduced to 1.50:1.00 until September 30, 1997.
 
  The Company also covenanted that it will not permit the ratio of Senior
Funded Indebtedness to EBITDA on the last day of any fiscal quarter, as of
such day for the immediately preceding four fiscal quarters, to be greater
than 2.5:1.0. Under the Amendment, the Company agreed that it will not permit
the ratio of Total Funded Indebtedness to EBITDA on the last day of any fiscal
quarter, as of such day for the immediately preceding four fiscal quarters, to
be less than those set forth below:

  Finally, the Company covenanted that it will not permit the ratio of
Indebtedness for Borrowed Money to Total Capitalization on the last day of any
fiscal quarter ending in the periods set forth below to be greater than the
ratio set forth opposite such period:
 
<TABLE>

</TABLE>
 
  Under the Amendment, the ratio of Indebtedness for Borrowed Money to Total
Capitalization is 0.86:1.00 from the date of the Amendment through the
termination of the Credit Facility.
 
  Under the Credit Facility as amended by the Amendment, the Company and its
Subsidiaries agreed not to assume, incur, or create any Indebtedness for
Borrowed Money except for (i) the loans and letters of credit under
 
                                      65

covenants and restrictions, including, without limitation, restrictions on (i)
the creation of liens, (ii) mergers, consolidations, and other extraordinary
transactions, (iii) guarantees, (iv) loans, and (v) transfers and sale of
assets. Investments in project related joint ventures are limited to $500,000

limited to an aggregate of $7.5 million. In addition, the Credit Facility
limits Acquisitions to an aggregate of $5 million (excluding the value of the
Company's Capital Stock used for Acquisitions), with any single Acquisition
not to exceed $2 million; the Amendment provides that except for one specified
investment, no acquisitions or investments can be made during the time the
Over Advance Provision is outstanding. The Credit Facility also contains
restrictions against the Company's making any redemptions, repurchases,
dividends or distributions of any kind in respect of its Capital Stock, other
than  redemptions, repurchases, dividends or distributions payable in the form
of the Company's Capital Stock or with the net proceeds of the sale of the
Company's Capital Stock (other than to a Subsidiary or employee stock
ownership plan of the Company).
 
  Events of Default. The Credit Facility provides for various events of
default, including, among others: (i) the failure to pay any principal or
interest on, or any other amount owing in respect of any loans under the
Credit Facility when due and payable, (ii) the breach of certain specified
covenants and restrictive covenants contained in the Credit Facility; (iii)
the failure by the Company or any Subsidiary to pay when due any Indebtedness
for Borrowed Money in excess of $1 million (other than that incurred pursuant
to the Credit Facility); (iv) the failure of the Company to observe or perform

     DESCRIPTION OF $125 MILLION OF 12% SENIOR SUBORDINATED NOTES DUE 2003
 
  On January 11, 1994, the Company completed a sale of $125,000,000 principal
amount of 12% Senior Subordinated Notes due 2003. The terms of these Existing
Notes are identical in all material respects to the terms of the Old Notes and
the Exchange Notes offered pursuant to this Prospectus, except that (i) unlike
the Old Notes, the Existing Notes were registered under the Securities Act and
therefore do not have legends restricting their transfer, (ii) the Holders of
the Existing Notes have priority over the Holders of the Notes with respect to
the repurchase of the Existing Notes from the cash and Cash Equivalent portion
of the Net Proceeds of Asset Sales (capitalized terms have the meanings
assigned to them in the Existing Indenture relating to the Existing Notes),
(iii) certain definitions and covenants included in the Existing Indenture
refer to, or have the effect as of, the date of, or dates preceding the date
of, the Existing Indenture (January 11, 1994), whereas such definitions and
covenants in the Indenture relating to the Old Notes and the Exchange Notes
refer to, or have effect as of, the date of, or dates preceding the date of,
the Indenture (December 23, 1996) and (iv) the Existing Notes are subordinated
in right of payment to all existing and future senior indebtedness of the
Company.

<PAGE>
 
                           DESCRIPTION OF THE NOTES
 
  The Exchange Notes will be issued pursuant to an Indenture dated as of
December 23, 1996 (the "Indenture") between the Company and The Bank of New
York, as trustee (the "Trustee"), which also serves as the Trustee under the
Existing Indenture. The terms of the Exchange Notes are the same in all
respects (including principal amount, interest rate, maturity, security and
ranking) as the terms of the Old Notes for which they may be exchanged
pursuant to the Exchange Offer, except that the Exchange Notes (i) are freely
transferable by holders thereof (except as provided below) and (ii) are not
entitled to certain registration rights and certain additional interest
provisions that are applicable to the Old Notes under the Registration Rights
Agreement. Unless the context otherwise requires, all references herein to the
"Notes" shall include the Old Notes and the Exchange Notes.
 
  The following is a summary of the material terms and provisions of the
Notes. The terms of the Notes include those set forth in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act. The
Notes are subject to all such terms. The following summary does not purport to
be a complete description of the Notes and is subject to the detailed
provisions of, and qualified in its entirety by reference to, the Indenture
and the Notes. Capitalized terms that are used but not otherwise defined
herein have the meanings assigned to them in the Indenture. The Bank Credit
Agreement referred to in the Indenture and herein is the Credit Facility.
Certain definitions from the Indenture are set forth below under "--Certain
Definitions."
 
GENERAL
 
  The Notes are senior unsecured obligations of the Company. The Notes bear
interest at 12% per annum, payable on June 30 and December 31 of each year, to
holders of record at the close of business on June 15 or December 15, as the
case may be, immediately preceding the relevant interest payment date. The
Notes will mature on December 31, 2003.
 
  The Exchange Notes will bear interest from December 31, 1996. Holders of Old
Notes whose Old Notes are accepted for exchange will be deemed to have waived
the right to receive any payment in respect of interest on the Old Notes
accrued from December 31, 1996 to the date of the issuance of the Exchange
Notes.
 
  The Exchange Notes will be issued only in registered form, without coupons,
in denominations of $1,000 and integral multiples thereof. Principal of,
premium, if any, and interest on the Old Notes is payable and on the Exchange
Notes will be payable, and the Notes may be presented for registration of
transfer or exchange, at the office of the Trustee. Payments may be paid by
check mailed to the registered addresses of the holders of record (the
"Holders") of the Notes. The Holders must surrender their Notes to the Paying
Agent to collect principal payments. The Company may require payment of a sum
sufficient to cover any transfer tax or other governmental charge payable in
connection with certain transfers or exchanges of the Notes. Initially, the
Trustee under the Existing Indenture will be the Paying Agent and the
Registrar under the Indenture. The Company or any of its Subsidiaries
subsequently may act as the Paying Agent and the Registrar, and the Company
may change any Paying Agent and any Registrar without prior notice to the
Holders.
 
INTEREST RATE INCREASE
 
  The interest rate on the Old Notes is increased and on the Exchange Notes
will be increased by one percent (from 12% to 13%) until the Company achieves
and maintains $36 million of earnings after deducting minority interests and
before interest, taxes, depreciation, and amortization calculated in
accordance with generally accepted accounting principles ("Earnings"). The
Company will measure its Earnings for trailing twelve month periods, each
period to end on the last day of a fiscal quarter and to extend no further
than March 31, 1998 (each a "Quarterly Measurement Period"). If, prior to
March 31, 1998, the Company's Earnings equal or exceed $36 million for two
consecutive Quarterly Measurement Periods, then the interest rate will revert
to 12%. However, if the Company's Earnings do not equal or exceed $36 million
for any subsequent Quarterly Measurement Period, up to and including the
Quarterly Measurement Period ending March 31, 1998, the interest rate will
 
                                      67
<PAGE>
 
increase to 13% until the Company's Earnings again equal or exceed $36 million
for one fiscal quarter on a trailing twelve month basis. The Company's
Earnings for the trailing twelve month period ended September 30, 1996, were
approximately $31.3 million.
 
RANKING
 
  The Old Notes are and the Exchange Notes will be senior unsecured
obligations of the Company, rank senior to all subordinated indebtedness of
the Company and rank pari passu in right of payment with all existing and
future senior indebtedness of the Company, including indebtedness under the
Credit Facility.
 
SUBSIDIARY GUARANTEES
 
  Four wholly owned subsidiaries of the Company (the "Subsidiary Guarantors")
have unconditionally guaranteed the payment of the principal, premium, if any,
and interest on the Notes. The Subsidiary Guarantors are Cygna Consulting
Engineers and Project Management, Inc., ICF Kaiser Government Programs, Inc.,
PCI Operating Company, Inc. and Systems Applications International, Inc. Cygna
Consulting Engineers and Project Management, Inc. is incorporated under the
laws of the State of California, and the other Subsidiary Guarantors are
incorporated under the laws of the State of Delaware. All four Subsidiary
Guarantors are Subsidiary Guarantors under the Existing Indenture and the Bank
Credit Agreement.
 
OPTIONAL REDEMPTION OF THE NOTES
 
  The Notes may not be redeemed prior to December 31, 1998, but will be
redeemable at the option of the Company, in whole or in part, at any time on
or after December 31, 1998, at the following redemption prices (expressed as
percentages of principal amount), together with accrued and unpaid interest,
if any, thereon to the redemption date, if redeemed during the 12-month period
beginning December 31:

         2002..................................      101.6
</TABLE>
 
  If less than all of the Notes are to be redeemed at any time, selection of
the Notes to be redeemed will be made by the Trustee from among the
outstanding Notes on a pro rata basis, by lot or by any other method permitted
in the Indenture. Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to
be redeemed at the registered address of such Holder. On and after the
redemption date, interest will cease to accrue on the Notes or portions
thereof called for redemption.
 
CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, the Company will offer (a
"Change of Control Offer") to purchase all outstanding Notes at a purchase
price equal to 101% of the aggregate principal amount of the Notes, plus
accrued and unpaid interest, if any, to the date of purchase.
 
  Within 30 days after any Change of Control, the Company, or the Trustee at
the Company's request, will mail or cause to be mailed to all Holders on the
date of the Change of Control a notice stating: (i) that a Change of Control
has occurred and that the Holders have the right to require the Company to
purchase any or all of the outstanding Notes at a purchase price equal to 101%
of the principal amount thereof plus accrued and unpaid interest, if any, to
the date of purchase; (ii) the circumstances and relevant facts regarding such
Change of Control; (iii) the purchase date; and (iv) the instructions that
Holders must follow in order to have their Notes purchased. Any Change of
Control Offer will be conducted in compliance with applicable tender offer
rules,
 
                                      68
<PAGE>
 
including Section 14(e) of the Securities Exchange Act of 1934, as amended,
and Rule 14e-1 thereunder. The Change of Control purchase feature of the Notes
in certain circumstances may discourage a sale or takeover of the Company or
make such a sale or takeover more difficult.
 
  Change of Control is defined to include the sale, lease, conveyance, or
other disposition of all or "substantially all" of the Company's assets.
Although there is a developing body of case law interpreting the phrase
"substantially all," there is no precise established definition of the phrase
under applicable law. Accordingly, the ability of a holder of Notes to require
the Company to repurchase such Notes as a result of a transfer or lease of the
Company's assets to another person may be uncertain. There can be no assurance
that, at the time of a Change of Control, the Company will have sufficient
cash to repay all amounts due under the Existing Notes and the Notes.
 
CERTAIN COVENANTS
 
  Limitations on Additional Indebtedness. The Indenture provides that (i) the
Company 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 (collectively, "incur"), any
Indebtedness (including without limitation Acquired Indebtedness), other than
(a) Junior Subordinated Indebtedness incurred by the Company in compliance
with the provisions of the immediately following sentence or (b) Indebtedness
between the Company and its Wholly Owned Restricted Subsidiaries (provided
that such Indebtedness of the Company to any Wholly Owned Restricted
Subsidiary is expressly subordinated in right of payment to the Notes) or
among such Wholly Owned Restricted Subsidiaries (provided, however, that any
subsequent issue or transfer of any Capital Stock that results in any such
Wholly Owned Restricted Subsidiary ceasing to be a Wholly Owned Restricted
Subsidiary or any transfer of such Indebtedness (other than to a Wholly Owned
Restricted Subsidiary) shall be deemed, in each case, to constitute the
incurrence of such Indebtedness by the Company) and (ii) the Company will not
permit any of its Restricted Subsidiaries to issue (except to the Company or
any of its Wholly Owned Restricted Subsidiaries) any Capital Stock having a
preference in liquidation or with respect to the payment of dividends, unless,
after giving effect thereto, the Company's Consolidated Fixed Charge Coverage
Ratio on the date thereof would be at least:
 
    (1) 2.25 to 1, if such date is on or prior to February 28, 1998; and
 
    (2) 2.50 to 1, if such date is after February 28, 1998,
 
in each case determined on a pro forma basis as if the incurrence of such
additional Indebtedness or the issuance of such Capital Stock, as the case may
be, and the application of the net proceeds therefrom, had occurred at the
beginning of the four-quarter period used to calculate the Company's
Consolidated Fixed Charge Coverage Ratio. In addition, after the date hereof
the Company will not directly or indirectly incur any Junior Subordinated
Indebtedness unless, after giving effect thereto, the Company's Consolidated
Fixed Charge Coverage Ratio on the date thereof would be at least 1.50 to 1,
in each case determined on a pro forma basis as if the incurrence of such
additional Indebtedness, and the application of the net proceeds therefrom,
had occurred at the beginning of the four-quarter period used to calculate the
Company's Consolidated Fixed Charge Coverage Ratio.
 
  Notwithstanding the immediately preceding paragraph, the Company and its
Restricted Subsidiaries may: (i) incur Indebtedness under the Bank Credit
Agreement in an amount not to exceed $60,000,000; (ii) incur Indebtedness not
otherwise permitted by any other provision hereof, so long as the aggregate
principal amount of Indebtedness incurred under this clause (ii) does not
exceed 7.5% of the Consolidated Tangible Assets of the Company; and (iii)
incur Refinancing Indebtedness. In addition, notwithstanding the provisions of
Section 5.04(a): (A) Subsidiaries of the Company that are not Wholly Owned
Restricted Subsidiaries may incur Indebtedness to the Company of any of its
Wholly Owned Restricted Subsidiaries in the amounts and subject to the
restrictions in Section 5.05(iii) and (B) Single Purpose Subsidiaries of the
Company may incur Non-Recourse Indebtedness to the extent permitted by Section
5.05(iv).
 
 
                                      69
<PAGE>
 
  Notwithstanding the two preceding paragraphs, the Company may not incur any
Indebtedness if such Indebtedness is subordinated or junior in ranking in any
respect to any Senior Indebtedness unless such Indebtedness is Junior
Subordinated Indebtedness. In addition, the Company may not incur any secured
Indebtedness which is not Senior Indebtedness unless contemporaneously
therewith effective provision is made to secure the Notes equally and ratably
with such secured Indebtedness for so long as such secured Indebtedness is
secured by a Lien.
 
  Limitations on Subsidiary Debt and Preferred Stock. The Indenture further
provides that the Company 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 (collectively,
"incur"), any Indebtedness (which, with respect to any Restricted Subsidiary,
includes without limitation preferred stock of such Restricted Subsidiary)
except: (i) guarantees by any Restricted Subsidiary of the payment of the
principal of, premium, if any, and interest on the Indebtedness incurred
pursuant to the Bank Credit Agreement and in compliance with the provisions of
Section 5.11; (ii) Indebtedness issued to and held by the Company or a Wholly
Owned Restricted Subsidiary of the Company (provided, however, that any
subsequent issue or transfer of any Capital Stock that results in any such
Wholly Owned Restricted Subsidiary ceasing to be a Wholly Owned Restricted
Subsidiary or any transfer of such Indebtedness (other than to a Wholly Owned
Restricted Subsidiary) shall be deemed, in each case, to constitute the
incurrence of such Indebtedness by such Restricted Subsidiary); (iii)
Indebtedness to the Company or any of its Wholly Owned Restricted Subsidiaries
incurred by Subsidiaries of the Company that are not 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 in compliance with the provisions of
Section 5.06(b)(E)) not to exceed 5% of Consolidated Tangible Assets; and (iv)
Non-Recourse Indebtedness incurred by a Single Purpose Subsidiary.
 
  Limitations on Restricted Payments. The Indenture provides that the Company
will not, and will not permit any of its Restricted Subsidiaries to, directly
or indirectly, make any Restricted Payment if at the time of such Restricted
Payment:
 
    (i) a Default or Event of Default shall have occurred and be continuing
  or shall occur as a consequence thereof;
 
    (ii) the Company would be 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
 
    (iii) the amount of such Restricted Payment, when added to the aggregate
  amount of all Restricted Payments (other than those made pursuant to the
  provisions of clause (A), (C), (D), (E) or (G) of the immediately following
  paragraph) made after the date of this Indenture exceeds the sum of: (a)
  50% of the Company's Consolidated Net Income accrued during the period from
  September 30, 1996 to the end of the Company's most recent fiscal quarter
  for which financial results have been reported at the time of such
  Restricted Payment (or, if such aggregate Consolidated Net Income shall be
  a deficit, minus 100% of such aggregate deficit); plus (b) the aggregate
  amount of Net Reductions in Investments attributable to Designated
  Investments made by the Company or any Subsidiary subsequent to the date of
  this Indenture; provided, however, that (1) the Net Reductions in
  Investments attributable to any Designated Investment for purposes of this
  calculation shall not exceed the amount of such Designated Investment, (2)
  to the extent that cash or Cash Equivalents included in any Net Reductions
  in Investments pursuant to the definition thereof have been or will be
  included in the computation of Consolidated Net Income for purposes of
  determining the ability of the Company or any of its Restricted
  Subsidiaries to make Restricted Payments under clause (iii)(a) of this
  paragraph, such cash or Cash Equivalents shall not also be included in
  computing Net Reductions in Investments for purposes of this clause
  (iii)(b) and (3) the Company will not be permitted to make any Restricted
  Payment described in clause (i) or (ii) of the definition of Restricted
  Payment from any Net Reductions in Investments.

  Notwithstanding the foregoing, the provisions of clauses (ii) and (iii) of
the immediately preceding paragraph will not prevent:
 
    (A) the Company or any Wholly Owned Restricted Subsidiary from making
  Investments in Subsidiaries, in an aggregate amount not to exceed
  $4,000,000, pursuant to contractual obligations in existence on the date of
  the Indenture or directly related to projects in existence on the date of
  the Indenture;
 
    (B)  the Company from paying any dividend within 60 days after the date
  of its declaration if such dividend could have been paid on the date of its
  declaration without violation of this covenant;
 
    (C) the Company from purchasing or redeeming and retiring any shares of
  Capital Stock of the Company, and paying accrued and unpaid dividends on
  such shares at the time of such repurchase or redemption, in exchange for,
  or out of the net proceeds of a substantially concurrent sale (other than
  to a Subsidiary of the Company or an employee stock ownership plan) of
  shares of Qualified Capital Stock of the Company;
 
    (D) the Company or any Subsidiary from making (1) Investments pursuant to
  the provisions of employee benefit plans of the Company or any of its
  Subsidiaries in an aggregate amount not to exceed $500,000 in any fiscal
  year, or (2) making loans to officers of the Company in connection with any
  relocation of residence, approved by a majority of the independent members
  of the Board of Directors of the Company, provided that the aggregate
  amount of Investments and loans under this clause (D) shall not exceed $1
  million in any fiscal year;
 
    (E) the Company or any Wholly Owned Restricted Subsidiary from making
  Designated Investments (1) 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 clause (iii)
  of the covenant described under "Limitations on Subsidiary Debt and
  Preferred Stock) not to exceed 5% of Consolidated Tangible Assets or (2) in
  Joint Ventures in an aggregate amount not to exceed 5% of Consolidated
  Tangible Assets, provided that: (x) the Person in whom the Investment is
  made is engaged only in Permitted Businesses; (y) the Company, directly or
  through Wholly Owned Restricted Subsidiaries of the Company, controls,
  under an operating and management agreement or otherwise, the day to day
  management and operation of such Person or otherwise has the right to
  exercise significant influence over the management and operation of such
  Person in all material respects (including without limitation the right to
  control or veto any material act or decision); and (z) after giving effect
  to such Investment, the aggregate amount of Indebtedness and Investments
  made by the Company and its Subsidiaries in such Person does not exceed $5
  million;
 
    (F) the Company or any Wholly Owned Restricted Subsidiary from making
  Designated Investments in Subsidiaries that are not Wholly Owned Restricted
  Subsidiaries or in Joint Ventures; provided that such Designated
  Investments are made solely from (1) the net proceeds of a substantially
  concurrent sale (other than to a Subsidiary of the Company or an employee
  stock ownership plan) of shares of Qualified Capital Stock of the Company,
  (2) 50% of the Company's Consolidated Net Income accrued during the period
  from September 30, 1996 to the end of the Company's most recent fiscal
  quarter for which financial results have been reported at the time of such
  Restricted Payment, or (3) the aggregate amount of Net Reductions in
  Investments (not to exceed the aggregate amount of such Designated
  Investments) made by the Company or any Subsidiary subsequent to the date
  of the Indenture;
 
    (G) the Company from redeeming for cash all (but not less than all) of
  the outstanding shares of the Company's Series 2D Senior Preferred Stock;
  provided, however, that such redemption shall not be at a price in excess
  of the redemption price set forth in Section 17.01 of the Company's Amended
  and Restated Certificate of Incorporation in effect as of January 11, 1994;
  and provided, further, that prior to January 13, 1997, the Company shall
  not redeem any of the outstanding shares of the Company's Series 2D Senior
  Preferred Stock until the Company delivers to the Trustee an Officers'
  Certificate certifying that the Company's earnings before interest and
  taxes for the most recent twelve (12) month period calculated in accordance
  with generally accepted accounting principles equaled or exceeded $27
  million. Nothing contained in this further proviso shall affect the
  Company's right to redeem the Series 2D Senior Preferred Stock no later
  than January 13, 1997; or
 
                                      71
<PAGE>
 
    (H) the Company from (1) making all regular quarterly dividends, each
  such quarterly dividend payment not to exceed $487,500 in the aggregate or
  $2,437.50 per share, on the outstanding shares of the Company's Series 2D
  Senior Preferred Stock; and (2) making all payments of any dividends of up
  to 9.75% on the aggregate unpaid amount of any regular quarterly dividend
  on the outstanding shares of the Company's Series 2D Senior Preferred Stock
  from the date such regular quarterly dividend should have been paid to the
  date of the payment of such dividend; in consideration thereof, and except
  as provided below, the Company increased the Interest payable on the Notes
  by one percent (1%) (the "Additional Interest") from the date of the
  Indenture, such Additional Interest payable as provided for in the Notes.
  The Company files its financial results with the Securities and Exchange
  Commission on quarterly and annual reports, and these reports include the
  Company's earnings after deducting minority interests and before interest,
  taxes, depreciation, and amortization calculated in accordance with
  generally accepted accounting principles ("Earnings"). The Company will
  measure its Earnings for trailing twelve month periods, each period to end
  on the last day of a fiscal quarter and extend no further than March 31,
  1998 (each a "Quarterly Measurement Period"). If the Company's Earnings
  equal or exceed $36 million for two consecutive Quarterly Measurement
  Periods, then the Company is relieved of its obligation to pay any future
  Additional Interest. However, if the Company's Earnings do not equal or
  exceed $36 million for any subsequent Quarterly Measurement Period, up to
  and including the Quarterly Measurement Period ending March 31, 1998, the
  Company is obligated to commence paying Additional Interest until the
  Company's Earnings again equal or exceed $36 million on a trailing twelve
  month basis calculated quarterly.
 
  Limitations on Restrictions on Distributions from Subsidiaries. The
Indenture provides that the Company 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 (i) Payment Restrictions covering not more
than $1,000,000 in the aggregate of retained earnings of ICF Kaiser Servicios
Ambientales, S.A. de C.V., (ii) any such Payment Restriction contained in
Existing Indebtedness or existing contracts to which the Company or any of its
Restricted Subsidiaries are parties, (iii) any such Payment Restriction under
any agreement evidencing any Acquired Indebtedness that was permitted to be
incurred pursuant to the provisions of this Indenture, provided that such
Payment Restriction only applies to assets that were subject to such
restrictions and encumbrances prior to the acquisition of such assets by the
Company or its Restricted Subsidiaries and (iv) any such Payment Restriction
arising in connection with Refinancing Indebtedness; provided that any such
Payment Restrictions that arise under such Refinancing Indebtedness are not,
taken as a whole, more restrictive than those under the agreement creating or
evidencing the Indebtedness being refunded or refinanced.
 
  Limitations on Transactions with Affiliates. The Indenture provides that the
Company 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 the Company or any of its Subsidiaries (each an "Affiliate Transaction"),
other than Affiliate Transactions in the ordinary course of business and
consistent with past practice that are fair to the Company of such Restricted
Subsidiary, as the case may be, and are on terms at least as favorable as
would have been obtainable at such time from an unaffiliated party, unless the
Board of Directors of the Company or such Restricted Subsidiary, as the case
may be, pursuant to a Board Resolution reasonably and in good faith determines
that such Affiliate Transaction is fair to the Company or such Restricted
Subsidiary, as the case may be, and is on terms at least as favorable as would
have been obtainable at such time from an unaffiliated party. In addition, the
Company will not, and will not permit any of its Restricted Subsidiaries to,
enter into any Affiliate Transaction or series of Affiliate Transactions
involving or having a value of more than (i) $1 million unless a majority of
the members of the Board of Directors of the Company who are not affiliated
with any other party to such Affiliate Transaction reasonably and in good
faith shall have determined that such Affiliate Transaction or series of
Affiliate Transactions is fair to the Company or such Restricted Subsidiary,
as the case may be, and is on terms at least as favorable as would have been
obtainable at such time from an unaffiliated party and (ii) $5 million unless
the Company or such
 
                                      72
<PAGE>
 
Restricted Subsidiary, as the case may be, has received an opinion from an
Independent Financial Advisor to the effect that the financial terms of such
Affiliate Transaction are fair to the Company or such Restricted Subsidiary,
as the case may be, from a financial point of view.
 
  The provisions of the foregoing paragraph shall not apply to: (i)
transactions exclusively between or among the Company and any of its Wholly
Owned Restricted Subsidiaries or exclusively between or among any of the
Company's Wholly Owned Restricted Subsidiaries, provided that such
transactions are not otherwise prohibited by the Indenture; (ii) arms-length
transactions between the Company or any of its Wholly Owned Restricted
Subsidiaries and the other owners of any Subsidiary or Joint Venture described
in the last sentence of the definition of Affiliate; and (iii) reasonable
compensation, indemnification and other benefits paid or made available to
officers, directors and employees of the Company or any Subsidiary for
services rendered in such Person's capacity as an officer, director or
employee.
 
  Limitations on Asset Sales. The Indenture provides that the Company will
not, and will not permit any of its Restricted Subsidiaries to, consummate any
Asset Sale unless: (i) the Company or its Restricted Subsidiaries receive
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets or Capital Stock included in such Asset Sale; (ii) the
aggregate fair market value of the consideration from such Asset Sale (other
than consideration in the form of assumption of Indebtedness of the Company or
one or more of its Restricted Subsidiaries from which the Company or such
Restricted Subsidiaries, as the case may be, are released) that is not in the
form of cash or Cash Equivalents shall not, when aggregated with the fair
market value of all other non-cash or non-Cash Equivalent consideration
received by the Company and its Restricted Subsidiaries from all previous
Asset Sales since the date of this Indenture that have not yet been converted
into cash or Cash Equivalents, exceed 5% of Consolidated Tangible Assets of
the Company at the time of such Asset Sale; and (iii) if the aggregate fair
market value of the assets or Capital Stock to be sold in such Asset Sale
exceeds $3 million such Asset Sale has been approved by the Company's Board of
Directors.
 
  Within six months after consummation of any such Asset Sale (the Business
Day closest to the end of such six-month period is referred to as the "Asset
Sale Offer Date"), the Company shall, or shall cause the applicable Restricted
Subsidiary to: (i) reinvest the cash and Cash Equivalent portion of the Net
Proceeds of such Asset Sale in a manner that would constitute a Related
Business Investment; (ii) apply or cause to be applied the cash and Cash
Equivalent portion of the Net Proceeds of such Asset Sale to repay outstanding
Senior Indebtedness of the Company or any Restricted Subsidiary, provided,
however, that any such repayment of Indebtedness under any revolving credit
facility or similar agreement shall result in a permanent reduction in the
lending commitment relating thereto in an amount equal to the principal amount
so repaid; or (iii) apply or cause to be applied the cash and Cash Equivalent
portion of the Net Proceeds of such Asset Sale that is neither reinvested as
provided in clause (i) nor applied to the repayment of Senior Indebtedness as
provided in clause (ii), (x) first to the purchase of Existing Notes tendered
to the Company at a purchase price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest, if any, thereon to the date of
purchase, pursuant to an offer to purchase made by the Company as set forth in
Article 3 and Section 5.09 of the Existing Indenture and the Indenture (an
"Asset Sale Offer") and (y) second to the purchase of the Notes tendered to
the Company at a purchase price equal to 100% of the principal thereof, plus
accrued and unpaid interest, if any, thereon to the date of purchase, pursuant
to an Asset Sale Offer, provided, however, that the Company may defer the
Asset Sale Offer for the Existing Notes until the amount subject thereto would
be at least $5 million, and provided, further, that the Company may defer the
Asset Sale Offer for the Notes until remaining amount subject thereto would be
at least $5 million.
 
  Notwithstanding the foregoing provisions: (i) 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 such Net Proceeds so affected will not be required to be applied in the
manner set forth in this covenant but may be retained by the applicable
Foreign Subsidiary so long, but only so long, as the applicable local law will
not permit repatriation to the United States (the Company hereby agreeing to
cause the applicable Foreign Subsidiary promptly to take all actions required
by the applicable local law to permit such repatriation) and, once such
repatriation of any such affected Net Proceeds is permitted under the
applicable local law, such
 
                                      73
<PAGE>
 
repatriation will be immediately effected and such repatriated Net Proceeds
will be applied in a manner set forth in this covenant; and (ii) to the extent
that the Board of Directors has determined 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 so affected may be retained by the
applicable Foreign Subsidiary for so long as such material adverse tax
consequence would continue.
 
  Each Asset Sale Offer: (i) will be mailed to the record Holders of the Notes
as shown on the register of Holders of Notes, with a copy to the Trustee; (ii)
will specify the purchase date (which shall be no earlier than 30 days nor
later than 60 days from the date such notice is mailed and not later than 240
days after the date of the Asset Sale giving rise to such Asset Sale Offer);
and (iii) otherwise will comply with the procedures set forth in the
Indenture. Upon receiving notice of the Asset Sale Offer, Holders of Notes may
elect to tender their 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,
Notes of tendering Holders will be repurchased on a pro rata basis (based on
amounts tendered).
 
  The Company will comply with the requirements of Section 14(e) under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to any Asset Sale Offer.
 
  Restrictions on Sale of Stock of Subsidiaries. The Indenture provides that
the Company may not sell or otherwise dispose of any of the Capital Stock of
any Restricted Subsidiary of the Company unless: (i) (a) (x) the Company shall
retain ownership of more than 50% of the Common Equity of such Restricted
Subsidiary or (y) all of the Capital Stock of such Restricted Subsidiary shall
be sold or otherwise disposed of, and (b) the Net Proceeds from any such sale
or disposition are applied in a manner consistent with the provisions
described under "Limitations on Asset Sales"; or (ii) the Company elects to
treat the amount of its remaining investment in any such Restricted Subsidiary
that has become a Joint Venture as a result of such sale or other disposition
as an Investment in such Joint Venture subject to the provisions described
under "Limitations on Restricted Payments."
 
  Limitations on Mergers and Certain Other Transactions. The Indenture
provides that the Company, in a single transaction or a series of related
transactions, will not (i) 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 Notes or the Indenture, to any Person
or (ii) adopt a Plan of Liquidation unless, in either case: (a) the Person
formed by or surviving such consolidation or merger (if other than the
Company) or to which such sale, lease, conveyance or other disposition or
assignment shall be made (or, in the case of a Plan of Liquidation, one Person
to which assets are transferred) (collectively, the "Successor"), is a
corporation organized and existing under the laws of the United States or any
State thereof or the District of Columbia, and the Successor assumes by
supplemental indenture in a form satisfactory to the Trustee all of the
obligations of the Company under the Notes and the Indenture; (b) immediately
prior to and immediately after giving effect to such transaction and the
assumption of the obligations as set forth in clause (a) above and the
incurrence of any Indebtedness to be incurred in connection therewith, no
Default or Event of Default shall have occurred and be continuing; and (c)
immediately after and giving effect to such transaction and the assumption of
the obligations as set forth in clause (a) above and the incurrence of any
Indebtedness to be incurred in connection therewith, and the use of any net
proceeds therefrom on a pro forma basis, (1) the Consolidated Tangible Net
Worth of the Company or the Successor, as the case may be, would be at least
equal to the Consolidated Tangible Net Worth of the Company immediately prior
to such transaction and (2) the Company or the Successor, as the case may be,
could incur at least $1.00 of additional Senior Indebtedness under the
covenant described under "Limitations on Additional Indebtedness."
 
  In addition, the Indenture will provide that the Company will not permit any
Single Purpose Subsidiary that has outstanding Indebtedness to consolidate or
merge with any other Person other than a Person the activities of which are
limited to ownership of a portion of the same project in which the reference
Single Purpose Subsidiary owns an interest.
 
                                      74
<PAGE>
 
  The foregoing provisions of the Indenture will not prohibit a transaction
the sole purpose of which (as determined in good faith by the Board of
Directors and evidenced by a Board Resolution) is to change the state of
incorporation of the Company or a Single Purpose Subsidiary, as the case may
be, and such transaction does not have as one of its purposes the evasion of
the limitations described above.
 
  Limitations on Guarantees. The Indenture provides that the Company will not
permit any of its Restricted Subsidiaries to guarantee any Indebtedness (other
than (i) the Guarantors and (ii) guarantees delivered pursuant to the Bank
Credit Agreement by Subsidiaries of the Company who have delivered similar
guarantees prior to the date of the Indenture) unless the Company causes each
such Subsidiary to execute and deliver to the Trustee, prior to or
concurrently with the issuance of such guarantee, a supplemental indenture, in
form satisfactory to the Trustee, pursuant to which such Subsidiary
unconditionally guarantees the payment of principal of, premium, if any, and
interest on the Notes. Any such guarantee will be substantially in the form of
the Subsidiary Guarantee included as an Exhibit to the Indenture. See "--
Subsidiary Guarantees."
 
EVENTS OF DEFAULT
 
  An "Event of Default" is defined in the Indenture as (i) failure by the
Company to pay interest on any of the Notes when it becomes due and payable
and the continuance of any such failure for 30 days; (ii) failure by the
Company to pay the principal or premium of any of the Notes when they become
due and payable, whether at stated maturity, upon redemption, upon
acceleration or otherwise (including failure to make payment pursuant to a
Change in Control Offer or an Asset Sale Offer); (iii) failure by the Company
to comply with any covenant in the Indenture and continuance of such failure
for 60 days after notice of such failure has been given to the Company by the
Trustee or by the Holders of at least 25% of the aggregate principal amount of
the Notes then outstanding; (iv) failure by the Company or any of its
Subsidiaries to make any payment when due or during any applicable grace
period, and the continuation of such failure for seven days, in respect of any
Indebtedness of the Company or any of its Subsidiaries that has an aggregate
outstanding principal amount of $2 million or more, other than Non-Recourse
Indebtedness of a Single Purpose Subsidiary; (v) a default under any
Indebtedness, other than Non-Recourse Indebtedness of a Single Purpose
Subsidiary, if such default results in the holder or holders of such
Indebtedness causing such Indebtedness to become due prior to its stated
maturity and the principal amount of such Indebtedness, together with the
principal amount of any other such Indebtedness the maturity of which has been
so accelerated, aggregate $2 million or more at any one time outstanding; (vi)
one or more final judgments or orders that exceed $2 million in the aggregate
for the payment of money have been entered by a court or courts of competent
jurisdiction against the Company or any of its Subsidiaries and such judgment
or judgments have not been satisfied, stayed, annulled, or rescinded within 60
days of being entered; and (vii) certain events of bankruptcy, insolvency or
reorganization involving the Company or any of its Subsidiaries.
 
  If an Event of Default (other than an Event of Default resulting from
bankruptcy, insolvency or reorganization involving the Company) occurs and is
continuing under the Indenture, the Trustee by written notice to the Company,
or the Holders of at least 25% in aggregate principal amount of the Notes then
outstanding by written notice to the Company and the Trustee, may declare all
amounts owing under the Notes to be due and payable immediately. If an Event
of Default results from bankruptcy, insolvency or reorganization involving the
Company, all outstanding Notes shall become due and payable without any
further action or notice. In certain cases, the Holders of a majority in
aggregate principal amount of the Notes then outstanding may waive an existing
Default or Event of Default and its consequences, except that a default in the
payment of principal of, premium, if any, and interest on the Notes cannot be
so waived.
 
  The Holders may not enforce the provisions of the Indenture or the Notes
except as provided in the Indenture. Subject to certain limitations, Holders
of a majority in principal amount of the Notes then outstanding may direct the
Trustee in its exercise of any trust or power; however, such direction may not
conflict with the terms of the Indenture. The Trustee may withhold from the
Holders notice of any continuing Default or Event of Default (except any
Default or Event of Default in payment of principal of, premium, if any, or
interest on the Notes) if the Trustee determines that withholding such notice
is in the Holders' interest.
 
                                      75
<PAGE>
 
  The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture and, upon any Officer of the Company
becoming aware of any Default or Event of Default, a statement specifying such
Default or Event of Default and what action the Company is taking or proposes
to take with respect thereto.
 
DISCHARGE OF INDENTURE
 
  The Indenture permits the Company to terminate all of its obligations under
the Indenture, other than the obligation to pay the principal of, premium, if
any, and interest on the Notes, and certain other obligations at any time by
(i) depositing in trust with the Trustee, under an irrevocable trust
agreement, money, or U.S. government obligations in an amount sufficient to
pay principal of, premium, if any, and interest on the Notes to their maturity
or redemption, and (ii) complying with certain 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 will not recognize income,
gain, or loss for Federal income tax purposes as a result of the Company's
exercise of such 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.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
  Unless the consent of each Holder affected has been obtained, the Company
may not: (i) extend the maturity of any Note; (ii) affect the terms of any
scheduled payment of interest on or principal of the Notes (including without
limitation any redemption provisions); (iii) modify or eliminate any of the
provisions of the Indenture relating to a Change of Control; or (iv) reduce
the percentage of Holders necessary to consent to an amendment, supplement, or
waiver to the Indenture.
 
  Subject to certain exceptions, the Indenture or the Notes may be amended or
supplemented, 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 of, premium, if any, or interest on
the Notes or that resulted from the failure to comply with the covenant
described under "Change of Control") with the consent of Holders of at least a
majority in principal amount of the then outstanding Notes.
 
  Without the consent of any Holder, the Company and the Trustee may amend or
supplement the Indenture or the Notes to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place
of certificated Notes, to provide for the assumption of the Company'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.
 
CONCERNING THE TRUSTEE
 
  The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee is permitted to engage in
other transactions; however, if it acquires any conflicting interest as
defined in the Indenture, it must eliminate such conflict or resign. The
Indenture provides that, in case an Event of Default occurs and is not cured,
the Trustee is 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 such provisions, the Trustee is under no obligation to
exercise any of its rights or powers under the Indenture at the request of any
Holder, unless such Holder shall have offered to the Trustee security and
indemnity satisfactory to the Trustee.

evidenced by bonds, debentures, notes or other similar instruments; (iii) all
obligations of such Person in respect of letters of credit or other similar

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following discussion is a summary of the material United States Federal
income tax consequences relevant to the exchange of Old Notes for Exchange
Notes and the ownership and disposition of the Exchange Notes by holders
acquiring Exchange Notes pursuant to the Exchange Offer, and represents the
opinion of Crowell & Moring LLP, special tax counsel to the Company, insofar
as it relates to matters of law and legal conclusions. The discussion is based
on the current provisions of the Internal Revenue Code of 1986, as amended
(the "Code"), applicable Treasury Regulations, judicial authority and
administrative rulings and practice. Any of such authorities are subject to
change at any time by legislative, judicial or administrative action. Any such
changes may be applied retroactively in a manner that could adversely affect a
holder of the Exchange Notes. Further, there can be no assurance that the
Internal Revenue Service (the "IRS") will not take a contrary view, and no
rulings from the IRS have been or will be sought. This summary is for general
informational purposes only and does not purport to address specific tax
consequences that may be relevant to certain persons (including, for example,
foreign persons, financial institutions, broker-dealers, insurance companies
or tax-exempt organizations and persons in special situations such as those
who hold Exchange Notes as part of a straddle).
 
EACH HOLDER OF OLD NOTES IS URGED TO CONSULT ITS OWN TAX ADVISORS WITH RESPECT
TO FEDERAL INCOME TAX CONSIDERATIONS THAT MAY BE SPECIFIC TO IT, AS WELL AS
WITH RESPECT TO ANY STATE, LOCAL OR FOREIGN TAX CONSIDERATIONS OF THE EXCHANGE
OF OLD NOTES FOR EXCHANGE NOTES AND OF HOLDING OR DISPOSING OF THE EXCHANGE
NOTES.
 
EXCHANGE OF NOTES
 
  The exchange of Exchange Notes for Old Notes pursuant to the Exchange Offer
should not be treated as a taxable exchange for federal income tax purposes
because, other than the fact that the Exchange Notes will be registered, the
terms of the Exchange Notes will be identical in all material respects to the
terms of the Old Notes. The Holder must continue to include interest and
original issued discount in income as if the exchange had not occurred.
 
INTEREST AND ORIGINAL ISSUE DISCOUNT
 
  In general, a Holder of a debt instrument issued with original issue
discount ("OID") must include a portion of the OID in gross income as interest
in each taxable year or portion thereof in which the Holder holds the debt
instrument even if the Holder has not received a cash payment in respect of
such OID.
 
  Because the original Holders of the Old Notes also purchased warrants, each
Old Note will be treated as part of an "investment unit" for federal income
tax purposes. Under Treasury Regulations regarding OID (the "OID
Regulations"), the issue price of an investment unit is equal to the first
price at which a substantial amount of units are sold to the public (not
including bond houses, brokers, or similar persons or organizations acting in
the capacity of an underwriter, placement agent or wholesaler). The issue
price of a unit is then allocated between the securities comprising each unit
based on their relative fair market values. Under the OID Regulations, the
issuer's allocation is binding on all holders of the securities, unless a
holder explicitly discloses to the IRS that its allocation differs from that
of the issuer.
 
  The Company has allocated approximately $1.00 as the issue price of each
warrant. This allocation reflects the Company's judgment as to the value of
the warrants at the time of issuance. This allocation is not binding on the
IRS.
 
  Each Old Note bears OID equal to the excess of its "stated redemption price
at maturity" over its "issue price." The stated redemption price at maturity
of an Old Note and of an Exchange Note is the sum of its stated principal
amount and all other payments including interest payments due thereunder. The
OID Regulations, as modified by the contingent payment debt instrument rules
described below, will apply to the Exchange Notes.
 
                                      87
<PAGE>
 
  A Holder is generally required to include OID in income periodically over
the term of an Exchange Note without regard to when the cash or other payments
attributable to such income are received. In general, a Holder must include in
gross income for Federal income tax purposes the sum of the daily portions of
OID with respect to the Exchange Note for each day during the taxable year on
which such Holder holds the Exchange Note ("Accrued OID"). The daily portion
is determined by allocating to each day of any accrual period within a taxable
year a pro rata portion of the OID allocable to such accrual period. The
amount of such OID is equal to the adjusted issue price of the Exchange Note
(the issue price of the Old Note increased by the Accrued OID for all prior
accrual periods and decreased by any cash payments on the Old Note and the
Exchange Note) at the beginning of the accrual period multiplied by the yield
to maturity of the Exchange Note. For purposes of computing OID, the Company
will use six-month accrual periods that generally correspond to the
stated interest payment periods of the Exchange Notes, with the exception of
an initial short accrual period. Any payment made under an Exchange Note will
be treated first as a payment of OID (which was previously includable in
income) to the extent of OID that has accrued as of the date of payment and
has not been allocated to prior payments and second as a payment of principal
(which, generally, is not includable in income).
 
CONTINGENT PAYMENT DEBT INSTRUMENTS
 
  The Exchange Notes provide that if certain Earnings targets are achieved by
the Company, the Temporary Interest Rate of 13 percent will be reduced to 12
percent. See "Description of the Notes--Interest Rate Increase." Because the
Exchange Notes provide for a change in the interest rate in the event a
contingency is satisfied, the Exchange Notes will be treated as contingent
payment debt instruments and will be subject to different OID rules than debt
instruments providing only for noncontingent payments.
 
  Treasury Regulations provide that, with respect to a contingent payment debt
instrument issued for money such as the Exchange Notes (the "Contingent
Payment Debt Regulations"), interest on an Exchange Note must be taken into
account under the so-called noncontingent bond method, whether or not the
amount of any interest payment is fixed or determinable. The amount of
interest that is taken into account for each accrual period is determined by
constructing a projected payment schedule for the debt instrument and applying
rules similar to those described above for accruing OID on a noncontingent
debt instrument. If the actual amount of a contingent payment is not equal to
the projected amount, appropriate adjustments are made to reflect the
difference.
 
  Under this method, the amount of income, deductions, gain and loss with
respect to an Exchange Note has been computed based on the following steps:
 
    Step 1: The Company has determined the "comparable yield" of an Exchange
  Note by computing the yield at which the Company could issue a fixed-rate
  debt instrument with terms and conditions similar to those of the Exchange
  Notes.
 
    Step 2: A "projected payment schedule" which will produce the comparable
  yield has been determined by the Company. The projected payment schedule
  includes each noncontingent payment on an Exchange Note and an amount for
  each contingent payment based on the expected value of the contingent
  payment as of the issue date.
 
    Step 3: The daily portions of interest on an Exchange Note for a taxable
  year have been determined by multiplying the comparable yield times the
  adjusted issue price of an Exchange Note at the beginning of an accrual
  period, and allocating to each day in the accrual period the ratable
  portion of interest accruing in the period. The "adjusted issue price" of
  an Exchange Note is equal to the Exchange Note's issue price (as defined
  above), increased by any interest previously accrued (without regard for
  adjustments described in the following paragraph), and decreased by the
  amount of any noncontingent payment and the projected amount of any
  contingent payment previously made on the Exchange Note.
 
    Step 4: Adjustments are then made to the amount of interest attributable
  to an Exchange Note during a taxable year for any differences between
  projected and actual contingent payments. A positive adjustment is made if
  the amount of a contingent payment is more than the projected amount of the
  contingent payment. A negative adjustment is made if the amount of a
  payment is less than the projected amount of the payment.
 
                                      88
<PAGE>
 
  Positive and negative adjustments are netted at the end of a tax year, and
  a net positive adjustment is treated as additional interest to a Holder,
  while a net negative adjustment would reduce the amount of interest that a
  Holder would otherwise account for with respect to an Exchange Note.
 
  The Company's calculation of the comparable yield on the Exchange Notes and
the Company's projected payment schedule are used to determine a Holder's
interest, accruals and adjustments unless these determinations are
unreasonable and the Holder explicitly discloses to the IRS that its projected
payment schedule differs from that of the issuer. The Company will provide the
projected payment schedule to the Trustee for distribution to Holders of the
Exchange Notes.
 
SALE OR RETIREMENT OF NOTES
 
  A Holder's basis in an Exchange Note will be increased by the interest
previously accrued by the Holder on the Exchange Note as described above
(determined without regard for any adjustments), and decreased by the amount
of any noncontingent payment and the projected amount of any contingent
payment previously made on the Exchange Note. Upon the sale, exchange,
retirement or other disposition of an Exchange Note, a Holder will generally
recognize gain or loss equal to the difference between the amount realized on
the disposition and the Holder's adjusted tax basis in the Exchange Note. If
any contingent payment remains unpaid at the time of sale, exchange or
retirement of the Note, including a contingent payment due on the retirement
of an Exchange Note, then any gain recognized by a Holder is treated as
ordinary interest income for federal income tax purposes. Any loss recognized
by a Holder on the sale, exchange or retirement of an Exchange Note is
ordinary loss to the extent that the Holder's total interest inclusions on the
Exchange Note exceed the total net negative adjustments on the Exchange Note
that the Holder took into account as ordinary loss.
 
BOND PREMIUM, MARKET DISCOUNT, ACQUISITION PREMIUM NOT TO APPLY
 
  The Contingent Payment Debt Regulations provide that the premium and
discount rules of the OID Regulations do not apply to Contingent Payment Debt
Instruments. Instead, a Holder that purchases an Exchange Note for more or
less than the Exchange Note's adjusted issue price accrues interest on the
Exchange Notes based on the projected payment schedule determined as of the
issue date by the Company. However, upon acquisition, the Holder must allocate
any difference between the Exchange Note's adjusted issue price and the
Exchange Note's basis to daily portions of interest or to projected payments
over the remaining term of the Exchange Note. Where a Holder's basis is
greater than the Exchange Note's adjusted issue price, the allocation is
treated as a negative adjustment as described above. Where a Holder's basis is
less than the Exchange Note's adjusted issue price, the allocation is treated
as a positive adjustment as described above.
 
  The Contingent Payment Debt Regulations are very complex and this summary
does not purport to be a complete analysis or listing of all the potential tax
consequences which may be relevant to a decision to purchase the Exchange
Notes. Investors are urged to consult their own tax advisers regarding the
application of the Contingent Payment Debt Regulations to an investment in the
Exchange Notes.
 
BACKUP WITHHOLDING
 
  A Holder of an Exchange Note may be subject to backup withholding at the
rate of 31% with respect to interest paid on an Exchange Note and gross
proceeds upon the sale or retirement of an Exchange Note unless such holder
(a) is a corporation or other exempt recipient and, when required,
demonstrates this fact or (b) provides, when required, a correct taxpayer
identification number, certifies that backup withholding is not in effect and
otherwise complies with applicable requirements of the backup withholding
rules. Furthermore, a Holder of an Exchange Note that does not provide the
Company with the Holder's correct taxpayer identification number may be
subject to penalties imposed by the IRS. Backup withholding will be made when
cash payments are made with respect to the Exchange Notes. Backup withholding
is not an additional tax; any amounts so withheld are creditable against the
Holder's federal income tax liability.

              OLD NOTES REGISTRATION RIGHTS; ADDITIONAL INTEREST
 
  The Company and the Initial Purchaser have entered into a registration
rights agreement (the "Registration Rights Agreement") pursuant to which the
Company agreed, for the benefit of the holders of the Old Notes, that it
would, at its own cost, (i) within 45 days after the date of original issuance
of the Old Notes (December 23, 1996) (the "Issue Date"), file this
Registration Statement with respect to this Exchange Offer for the Exchange
Notes, which will have terms identical in all material respects to the Old
Notes (except that the Exchange Notes will not contain terms with respect to
transfer restrictions), (ii) use its best efforts to cause this Registration
Statement to be declared effective under the Securities Act within 135 days
after the Issue Date and (iii) use its best efforts to consummate the Exchange
Offer within 180 days after the Issue Date. The Company will keep the Exchange
Offer open for not less than 20 business days (or longer if required by
applicable law) after the date notice of the Exchange Offer is mailed to the
holders of the Old Notes. For each Old Note surrendered to the Company
pursuant to the Exchange Offer, the holder of such Old Note will receive an
Exchange Note having a principal amount equal to that of the surrendered Old
Note. Interest on each Exchange Note will accrue from December 31, 1996, the
last interest payment date on which interest was paid on the Old Notes
surrendered pursuant to the Exchange Offer.
 
  The Registration Rights Agreement also provides an agreement to include in
this Prospectus certain information necessary to allow a broker-dealer who
holds Old Notes that were acquired for its own account as a result of market-
making activities or other ordinary course trading activities (other than Old
Notes acquired directly from the Company or one of its Affiliates) and any
other person subject to the prospectus delivery requirements of the Securities
Act to exchange such Old Notes pursuant to the Exchange Offer and to satisfy
the prospectus delivery requirements in connection with resales of Exchange
Notes received by such person in the Exchange Offer and to maintain the
effectiveness of this Registration Statement and to amend and supplement this
Prospectus contained therein for such purposes for a period not to exceed 180
days after consummation of the Exchange Offer.
 
  Under existing interpretations of the Commission contained in several no-
action letters to third parties, the Exchange Notes would in general be freely
tradable after the Exchange Offer without further registration under the
Securities Act. However, any holder of Old Notes who is an Affiliate of the
Company within the meaning of the Securities Act or who intends to participate
in the Exchange Offer for the purpose of distributing the Exchange Notes (i)
will not be able to rely on the interpretation of the staff of the Commission,
(ii) will not be able to tender its Old Notes in the Exchange Offer and (iii)
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any sale or transfer of the Old Notes unless
such sale or transfer is made pursuant to an exemption from such requirements.
 
  Each holder of Old Notes who participates in the Exchange Offer will be
required to represent that at the time of commencement of the Exchange Offer
such holder will have no arrangement or understanding with any Person to
participate in the distribution of the Exchange Notes in violation of the
provisions of the Securities Act and that such holder is not an Affiliate of
the Company within the meaning of the Securities Act and is not acting on
behalf of any persons or entities who could not truthfully make the foregoing
representations.
 
  In the event that (i) any changes in law or the applicable interpretations
of the staff of the Commission do not permit the Company to effect the
Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days
after the Issue Date, (iii) if, under certain circumstances, after the
consummation of the Exchange Offer, the Initial Purchaser continues to hold
Exchange Notes and so requests, (iv) the holders of not less than a majority
in aggregate principal amount of the Registrable Notes (as defined in the
Registration Rights Agreement) determine that the interests of the holders
would be materially adversely affected by consummation of the Exchange Offer
or (v) in the case of any holder that participates in the Exchange Offer, such
holder does not receive Exchange Notes on the date of the exchange that may be
sold without restriction under state and Federal securities laws (other than
due solely to the status of such holder as an Affiliate of the Company within
the meaning of the Securities Act), then the Company shall promptly deliver to
the holders and the Trustee written notice thereof and, at its cost, as
promptly as reasonably practicable, file the Shelf Registration Statement.
 
                                      90

The Company shall use its best efforts to cause the Shelf Registration
Statement to be declared effective under the Securities Act as promptly as
reasonably practicable and to keep the Shelf Registration Statement
continuously effective under the Securities Act until three years after the
Issue Date or such shorter period ending when all Old Notes covered by the
Shelf Registration Statement have been sold in the manner set forth and as
contemplated in the Shelf Registration Statement. The Company will, in the
event of the filing of a Shelf Registration Statement, provide to each holder
of the Old Notes copies of the prospectus that is a part of the Shelf
Registration Statement, notify each such holder when the Shelf Registration
Statement for the Old Notes has become effective and take certain other
actions as are required to permit unrestricted resales of the Old Notes. A
holder of Old Notes that sells such Old Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
securityholder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Rights Agreement that are applicable to such a
holder (including certain indemnification obligations). In addition, each
holder of the Old Notes will be required to deliver information to be used in
connection with the Shelf Registration Statement and to provide comments on
the Shelf Registration Statement within the time periods set forth in the
Registration Rights Agreement in order to have its Old Notes included in the
Shelf Registration Statement and to benefit from the provisions regarding
liquidated damages set forth in the following paragraph.
 
  Although the Company intends that this Registration Statement become
effective, there can be no assurance that it will become effective. If the
Company fails to comply with the above provisions or if the Registration
Statement fails to become effective, then, as liquidated damages, additional
interest (the "Additional Interest") shall become payable in respect of the
Old Notes as follows:
 
    (i) if this Registration Statement or the Shelf Registration Statement is
  not filed within 45 days after the Issue Date, Additional Interest shall be
  accrued on the Old Notes over and above the stated interest at a rate of
  0.50% per annum for the first 90 days immediately following the 45th day
  after the Issue Date, such Additional Interest rate increasing by an
  additional 0.50% per annum at the beginning of each subsequent 90-day
  period;
 
    (ii) if this Registration Statement or the Shelf Registration Statement
  is not declared effective within 135 days after the Issue Date, then,
  commencing on the 136th day after the Issue Date, Additional Interest shall
  be accrued on the Old Notes over and above the stated interest at a rate of
  0.50% per annum for the first 90 days immediately following the 135th day
  after the Issue Date, such Additional Interest rate increasing by an
  additional 0.50% per annum at the beginning of each subsequent 90-day
  period; or
 
    (iii) if either (A) the Company has not exchanged the Exchange Notes for
  all Old Notes validly tendered in accordance with the terms of the Exchange
  Offer on or prior to 180 days after the Issue Date, or (B) this
  Registration Statement ceases to be effective at any time prior to the time
  that the Exchange Offer is consummated or (C) if applicable, the Shelf
  Registration Statement has been declared effective and such Shelf
  Registration Statement ceases to be effective at any time prior to the
  third anniversary of the Issue Date, then Additional Interest shall accrue
  on the Old Notes (over and above any interest otherwise payable on the Old
  Notes) at a rate of .50% per annum for the first 90 days commencing on (x)
  the 181st day after the Issue Date, in the case of clause (A) above, or (y)
  the date this Registration Statement ceases to be effective without being
  declared effective within five business days, in the case of clause (B)
  above, or (z) the day the Shelf Registration Statement ceases to be
  effective, in the case of clause (C) above, such Additional Interest rate
  increasing by an additional 0.50% per annum at the beginning of each
  subsequent 90-day period:
 
provided, however, that the Additional Interest rate on the Old Notes may not
exceed 2% per annum in the aggregate; provided further, that (1) upon the
filing of this Registration Statement or a Shelf Registration Statement (in
the case of clause (i) above), (2) upon the effectiveness of this Registration
Statement or a Shelf Registration Statement (in the case of clause (ii)
above), or (3) upon the exchange of Exchange Notes for all Old Notes tendered
(in the case of clause (iii)(A) above) or upon the effectiveness of this
Registration Statement that has ceased to remain effective (in the case of
clause (iii)(B) above), or upon the effectiveness of the Shelf Registration
Statement that has ceased to remain effective (in the case of clause (iii)(C)
above), Additional
 
                                      91
<PAGE>
 
Interest on the Old Notes as a result of such clause (i), (ii) or (iii) above
(or the relevant subclause thereof), as the case may be, shall cease to
accrue.
 
  Any amounts of Additional Interest due pursuant to clause (i), (ii) or (iii)
above will be payable in cash, semiannually on each June 30 and December 31 of
each year, commencing with the first such date occurring after any such
Additional Interest commences to accrue. The amount of Additional Interest
will be determined by multiplying the applicable Additional Interest rate by
the principal amount of the Notes, multiplied by a fraction, the numerator of
which is the number of days such Additional Interest rate was applicable
during such period (determined on the basis of a 360-day year consisting of
twelve 30-day months) and the denominator of which is 360.

Agreement does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which is an exhibit to this Registration Statement and is

                        OLD NOTES TRANSFER RESTRICTIONS
 
  Because the following restrictions will apply to any Old Notes held by
holders who do not participate in the Exchange Offer, holders of Old Notes are
advised to consult legal counsel prior to making any offer, resale, pledge or
transfer of any of the Old Notes.
 
  None of the Old Notes have been registered under the Securities Act and they
may not be offered or sold within the United States or to, or for the account
or benefit of, U.S. persons except pursuant to an exemption from, or in a
transaction not subject to, the registration requirements of the Securities
Act. Accordingly, the Old Notes were sold only (i) to a limited number of
"qualified institutional buyers" (as defined in Rule 144A promulgated under
the Securities Act) ("QIBs") in compliance with Rule 144A; (ii) to a limited
number of other institutional "accredited investors" (as defined in Rule
501(a)(1), (2), (3) or (7) promulgated under the Securities Act) ("Accredited
Investors") that, prior to their purchase of any Old Notes delivered to the
Initial Purchaser a letter containing certain representations and agreements;
and (iii) outside the United States to persons other than U.S. persons
("foreign purchasers," which term shall include dealers or other professional
fiduciaries in the United States acting on a discretionary basis for foreign
beneficial owners (other than an estate or trust)) in reliance upon Regulation
S under the Securities Act. As used herein, the term "United States" and "U.S.
person" have the meanings given to them in Regulation S under the Securities
Act.
 
  Each purchaser of Old Notes has been deemed to have represented and agreed
as follows:
 
    1. It purchased the Old Notes (and the related guarantees) for its own
  account or account with respect to which it exercises sole investment
  discretion and that it and any such account is (i) a QIB, and is aware that
  the sale to it is being made in reliance on Rule 144A; (ii) an Accredited
  Investor; or (iii) a foreign purchaser that is outside the United States
  (or a foreign purchaser that is a dealer or other fiduciary as referred to
  above).
 
    2. It acknowledged that the Old Notes have not been registered under the
  Securities Act and may not be offered or sold within the United States or
  to, or for the account or benefit of, U.S. persons except as set forth
  below.
 
    3. It shall not resell or otherwise transfer any of such Old Notes within
  three years after the original issuance of the Notes except (i) to the
  Company or any subsidiary thereof, (ii) inside the United States to a QIB
  in compliance with Rule 144A, (iii) inside the United States to an
  Accredited Investor that, prior to such transfer, furnishes (or has
  furnished on its behalf by a U.S. broker-dealer) to the Trustee a signed
  letter containing certain representations and agreements relating to the
  restrictions on transfer of the Old Notes (the form of which letter can be
  obtained from the Trustee), (v) outside the United States in compliance
 
                                      92
<PAGE>
 
  with Regulation S under the Securities Act, (v) pursuant to the exemption
  from registration provided by Rule 144 promulgated under the Securities Act
  (if available), or (vi) pursuant to an effective registration under the
  Securities Act.
 
    4. It agreed that it will give to each person to whom it transfers Old
  Notes notice of any restrictions on transfer of such Old Notes.
 
    5. It understands that the Old Notes bear, and if not exchanged pursuant
  to the Exchange Offer will continue to bear, a legend substantially to the
  following effect unless otherwise agreed by the Company and the holder
  thereof:
 
THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933,
AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
PERSONS EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER (1)
REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
RULE 144A PROMULGATED UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL
"ACCREDITED INVESTOR" (AS DEFINED IN RULE 501 (a) (1), (2), (3) OR (7)
PROMULGATED UNDER THE SECURITIES ACT) (AN "ACCREDITED INVESTOR") OR (C) IT IS
NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN
COMPLIANCE WITH REGULATION S PROMULGATED UNDER THE SECURITIES ACT, (2) AGREES
THAT IT WILL NOT WITHIN THREE YEARS AFTER THE ORIGINAL ISSUANCE OF THIS
SECURITY RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER
THEREOF OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED
INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A PROMULGATED UNDER THE
SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN INSTITUTIONAL ACCREDITED
INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHED (OR HAS FURNISHED ON ITS
BEHALF BY A U.S. BROKER-DEALER) TO THE TRUSTEE A SIGNED LETTER CONTAINING
CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON
TRANSFER OF THIS SECURITY), (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE
TRANSACTION IN COMPLIANCE WITH REGULATION S PROMULGATED UNDER THE SECURITIES
ACT, (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144
PROMULGATED UNDER THE SECURITIES ACT (IF AVAILABLE), OR (F) PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT
IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE
SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF
THIS SECURITY WITHIN THREE YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY,
IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER
MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE ISSUER SUCH
CERTIFICATIONS, WRITTEN LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM
MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO
AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE
TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE RESPECTIVE MEANINGS
GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.
 
    6. It acknowledged that the Trustee will not be required to accept for
  registration of transfer any Old Note acquired by it, except upon
  presentation of evidence satisfactory to the Company and the Trustee that
  the restrictions set forth herein have been complied with.
 
    7. It acknowledged that the Company, the Initial Purchaser and others
  will rely upon the truth and accuracy of the foregoing acknowledgments,
  representations and agreements and agreed that if any of the
  acknowledgments, representations or agreements deemed to have been made by
  its purchase of Old Notes are no longer accurate, it shall promptly notify
  the Company and the Initial Purchaser. If it acquired any Notes as a
  fiduciary or agent for one or more investor accounts, it represented that
  it has sole investment
 
                                      93
<PAGE>
 
  discretion with respect to each such account and it has full power to make
  the foregoing acknowledgments, representations and agreements on behalf of
  each account.
 
  Holders of Old Notes shall not sell or transfer Old Notes to, and each
purchaser of Old Notes represented and covenanted that it did not acquire the
Old Notes for or on behalf of, any pension or welfare plan (as defined in
Section 3 or the Employee Retirement Income Security Act of 1974 ("ERISA")),
except that such a purchase for or on behalf of a pension or welfare plan
shall be permitted:
 
      (1) to the extent such purchase is made by or on behalf of a bank
    collective investment fund maintained by the purchaser in which no plan
    (together with any other plans maintained by the same employer or
    employee organization) has an interest in excess of 10% of the total
    assets in such collective investment fund and the applicable conditions
    of Prohibited Transaction Exemption 91-38 issued by the Department of
    Labor are satisfied;
 
      (2) to the extent such purchase is made by or on behalf of an
    insurance company pooled separate account maintained by the purchaser
    in which, at any time while the Units are outstanding, no plan
    (together with any other plans maintained by the same employer or
    employee organization) has an interest in excess of 10% of the total of
    all assets in such pooled separate account and the applicable
    conditions of Prohibited Transaction Exemption 90-1 issued by the
    Department of Labor are satisfied;
 
      (3) to the extent such purchase is made on behalf of a plan by (A) an
    investment adviser registered under the Investment Advisers Act of 1940
    that had as of the last day of its most recent fiscal year total assets
    under its management and control in excess of $50,000,000 and had
    shareholders' or partners' equity in excess of $750,000, as shown in
    its most recent balance sheet prepared in accordance with generally
    accepted accounting principles, or (B) a bank as defined in Section
    202(a) of the Investment Advisers Act of 1940 with equity capital in
    excess of $1,000,000 as of the last day of its most recent fiscal year
    and, in either case, such investment adviser or bank is otherwise a
    qualified professional asset manager, as such term is used in
    Prohibited Transaction Exemption 84-14 issued by the Department of
    Labor, and the assets of such plan when combined with the assets of
    other plans established or maintained by the same employer (or
    affiliate thereof) or employee organization and manager by such
    investment advisor or bank, do not represent more than 20% of the total
    client assets managed by such investment advisor or bank and the
    applicable conditions of Prohibited Transaction Exemption 84-14 are
    otherwise satisfied; or
 
      (4) to the extent such plan is a governmental plan (as defined in
    Section 3 of ERISA) which is not subject to the provisions of Title I
    of ERISA or Section 4975 of the Code.
 
  Each purchaser of Old Notes also represented that (a) if it is an insurance
company, no part of the funds used to purchase the Old Notes purchased by it
constitutes assets allocated to any separate account maintained by it such
that the use of such funds constitutes a transaction in violation of Section
406 of ERISA or a Prohibited Transaction, as such term is defined in Section
4975 of the Code, which could be subject to, respectively, a civil penalty
assessed pursuant to Section 502 of ERISA or a tax imposed by Section 4975 of
the Code and (b) if it is not an insurance company, that no part of the funds
used to purchase the Old Notes purchased by it constitutes assets allocated to
any trust, plan or account which contains the assets of any employee pension
benefit plan, welfare plan or account prohibited pursuant to the preceding
paragraph of this "Transfer Restrictions."
 
  Holders of Old Notes are advised that the Prohibited Transaction Exemptions
described above do not relieve a fiduciary or other party from all prohibited
transaction provisions of the Code and ERISA and from ERISA's general
fiduciary responsibilities including, but not limited to, a fiduciary's
obligation to discharge his, her, or its duties solely in the interests of
participants and beneficiaries. As a result of the foregoing restrictions,
holders of Old Notes are advised to consult legal counsel prior to making any
offer, resale, pledge, hypothecation or other transfer or disposition of the
Old Notes or any interest therein.

<PAGE>
 
                         BOOK-ENTRY; DELIVERY AND FORM
 
  Old Notes are represented by a single, global Old Note in registered form,
registered in the name of the nominee of DTC. The Exchange Notes exchanged for
Old Notes represented by the global Old Note will be represented by one or
more global Exchange Notes in registered form (the "Global Note"), registered
in the name of the nominee of DTC. Exchange Notes issued to persons other than
QIBs or Accredited Investors in exchange for Old Notes held by such investors
will be issued only in certificated, fully registered, definitive form
("Certificated Notes"). Except as described herein, Exchange Notes in the form
of Certificated Notes will not be issued in exchange for the Global Note or
interests therein.
 
THE GLOBAL NOTE
 
  The Company expects that pursuant to procedures established by the DTC (i)
upon deposit of the Global Note, DTC or its custodian will credit, on its
internal system, portions of the Global Note which shall comprise the
corresponding respective principal amount of the Global Note to the respective
accounts of Persons who have accounts with such depository and (ii) ownership
of the Exchange Notes will be shown on, and the transfer of ownership thereof
will be effected only through, records maintained by DTC or its nominee (with
respect to interests of participants) and the records of participants (with
respect to interests of Persons other than participants). Ownership of
beneficial interests in the Global Note will be limited to Persons who have
accounts with DTC ("participants") or Persons who hold interests through
participants. QIBs may hold their interests in the Global Note directly
through DTC if they are participants in such system, or indirectly through
organizations that are participants in such system.
 
  So long as DTC, or its nominee, is the registered owner or holder of the
Global Note, DTC or such nominee will be considered the sole owner or holder
of the Exchange Notes represented by the Global Note for all purposes under
the Indenture. No beneficial owner of an interest in the Global Note will be
able to transfer such interest except in accordance with DTC's applicable
procedures, in addition to those provided for under the Indenture.
 
  Payments of the principal of, premium (if any) and interest on, the Global
Note will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. None of the Company, the Trustee or any Paying Agent will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Note
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interest.
 
  The Company expects DTC or its nominee, upon receipt of any payment of the
principal of, premium (if any) and interest on, the Global Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in any such Global
Note held through such participants will be governed by standing instructions
and customary practice, as is now the case with securities held for the
accounts of customers registered in the names of nominees for such customers.
Such payments will be the responsibility of such participants.
 
  Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and be settled in clearinghouse funds. If a
holder requires physical delivery of a Certificated Note for any reason,
including to sell Exchange Notes to Persons in states that require physical
delivery of such Exchange Notes or to pledge such Exchange Notes, such holder
must transfer its interest in the Global Note in accordance with the normal
procedures of DTC and the procedures set forth in the Indenture.
 
  DTC has advised the Company that DTC will take any action permitted to be
taken by a holder of Exchange Notes (including the presentation of Exchange
Notes for exchange as described below) only at the direction of one or more
participants to whose account the DTC interests in the Global Note is credited
and only in respect
 
                                      95
<PAGE>
 
of such portion of the aggregate principal amount of Exchange Notes as to
which such participant or participants has or have given such direction.
However, if there is an Event of Default under the Indenture, DTC will
exchange the Global Note for Certificated Notes which it will distribute to
its participants.
 
  DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its participants and facilitate the clearance and settlement of
securities transactions between participants through electronic book-entry
changes in accounts of its participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a participant, either directly or indirectly
("indirect participants").
 
  Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among participants of DTC, it is
under no obligation to perform such procedures, and such procedures may be
discontinued at any time. Neither of the Company nor the Trustee will have any
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.
 
CERTIFICATED NOTES
 
  If DTC is at any time unwilling or unable to continue as a depository for
the Global Note and a successor depository is not appointed by the Company
within 90 days, the Company will issue Certificated Notes in exchange for the
Global Note.
 
                             PLAN OF DISTRIBUTION
 
  Based on interpretations by the Staff set forth in no-action letters issued
to third parties, the Company believes that Exchange Notes issued pursuant to
the Exchange Offer in exchange for the Old Notes may be offered for resale,
resold and otherwise transferred by holders thereof (other than any holder
that is (i) an Affiliate of the Company, (ii) a broker-dealer who acquired Old
Notes directly from the Company or (iii) a broker-dealer who acquired Old
Notes as a result of market-making or other trading activities) without
compliance with the registration and prospectus delivery provisions of the
Securities Act provided that such Exchange Notes are acquired in the ordinary
course of such holders' business, and such holders are not engaged in, and do
not intend to engage in, and have no arrangement or understanding with any
person to participate in, a distribution of such Exchange Notes; provided that
broker-dealers ("Participating Broker-Dealers") receiving Exchange Notes in
the Exchange Offer will be subject to a prospectus delivery requirement with
respect to resales of such Exchange Notes. To date, the Staff has taken the
position that Participating Broker-Dealers may fulfill their prospectus
delivery requirements with respect to transactions involving an exchange of
securities such as the exchange pursuant to the Exchange Offer (other than a
resale of an unsold allotment from the sale of the Old Notes to the Initial
Purchaser) by means of this Prospectus. Pursuant to the Registration Rights
Agreement, the Company has agreed to permit Participating Broker Dealers and
other persons, if any, subject to similar prospectus delivery requirements to
use this Prospectus in connection with the resale of such Exchange Notes. The
Company has agreed that, for a period of 180 days after the Exchange Date, it
will make this Prospectus, and any amendment or supplement to this Prospectus,
available to any broker-dealer that requests such documents in the Letter of
Transmittal.
 
  Each holder of the Old Notes who wishes to exchange its Old Notes for
Exchange Notes in the Exchange Offer will be required to make certain
representations to the Company as set forth in "The Exchange Offer--Terms and
Conditions of the Letter of Transmittal." In addition, each holder who is a
broker-dealer and who
 
                                      96

receives Exchange Notes for its own account in exchange for Old Notes that
were acquired by it as a result of market-making activities or other trading
activities will be required to acknowledge that it will deliver a prospectus
in connection with any resale by it of such Exchange Notes.
 
  The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or at negotiated prices. Any
such resale may be made directly to purchasers or to or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer and/or the purchasers of any such Exchange Notes.
Any broker-dealer that resells Exchange Notes that were received by it for its
own account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
 
  The Company has agreed to pay all expenses incidental to the Exchange Offer
other than commissions and concession of any brokers or dealers and will
indemnify holders of Registrable Notes (as defined in the Registration Rights
Agreement) (including any brokers-dealers) against certain liabilities,
including liabilities under the Securities Act, as set forth in the
Registration Rights Agreement.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE A--BASIS OF PRESENTATION
 
  The accompanying consolidated financial statements of ICF Kaiser
International, Inc. and subsidiaries (the Company) (including Kaiser-Hill
Company, LLC, effective July 1, 1995), except for the December 31, 1995
balance sheet, are unaudited and have been prepared in accordance with
generally accepted accounting principles for interim financial information.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments considered necessary for a fair
presentation have been included. These statements should be read in
conjunction with the Company's audited consolidated financial statements and
footnotes thereto for the ten months ended December 31, 1995 and the
information included in the Company's Transition Report to the Securities and
Exchange Commission on Form 10-K for the ten months ended December 31, 1995.
Certain reclassifications have been made to the prior period financial
statements to conform to the presentation used in the September 30, 1996
financial statements.
 
NOTE B--SIGNIFICANT ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities (see Note F) at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  In 1996, the Company accelerated the procedures for obtaining approval from
the U.S. government for the Company's actual costs incurred in current
periods. As a result, in the third quarter of 1996, the Company's consulting
group was able to accelerate its process of billing on certain cost-
reimbursement contracts. The net effect of this accelerated process is the
recognition of an additional $2.3 million of operating income in the third
quarter of 1996.
 
NOTE C--MINORITY INTERESTS IN SUBSIDIARIES
 
  Certain of the Company's subsidiaries are partially owned by outside
parties. For financial reporting purposes, the assets, liabilities, results of
operations, and cash flows of these subsidiaries are included in the Company's
consolidated financial statements and the outside parties' interests are
reflected as minority interests.
 
NOTE D--NET INCOME (LOSS) PER COMMON SHARE
 
  Net income (loss) per common share is computed using net income (loss)
available for common shareholders, as adjusted under the modified treasury
stock method, and the weighted average number of common stock and common stock
equivalents outstanding during the periods presented. Common stock equivalents
include stock options and warrants and additional shares which will be or may
be issued in connection with acquisitions. The adjustments required by the
modified treasury stock method and for acquisition-related contingencies were
anti-dilutive for the loss period presented and immaterial to the income
periods presented. Therefore, the adjustments were excluded from earnings per
share computations.
 
NOTE E--LONG-TERM DEBT
 
  The Company's $40 million revolving credit facility became effective May 7,
1996, replacing the former credit facility which was due to expire October 31,
1996. The new credit facility expires June 30, 1998 and is provided by
CoreStates Bank, as agent bank, and two other banks (the Banks) with terms and
covenants similar to those under the former credit facility. ICF Kaiser
International, Inc. and certain of its subsidiaries, which are guarantors of
the new credit facility, have granted the Banks a security interest in their
accounts receivable and
 
                                      F-5

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                                  (UNAUDITED)
 
certain other assets. The new credit facility limits the payments of cash
dividends on common stock and requires the maintenance of specified financial
ratios. Total available credit is determined from a borrowing base calculation
based on eligible accounts receivable (billed and unbilled).
 
NOTE F--CONTINGENCIES
 
  In the course of the Company's normal business activities, various claims or
charges have been asserted and litigation commenced against the Company
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 the Company in such litigation.
 
  The Company 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. The Company 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 the Company by these agencies. Management
does not believe that there will be any material adverse effect on the
Company's financial position, results of operations, or cash flows as a result
of these investigations.
 
  The Company has a substantial number of cost-reimbursement contracts with
the U.S. government, the costs of which are subject to audit by the U.S.
government. As a result of pending audits relating to fiscal years 1986
forward, the government has asserted, among other things, that certain costs
claimed as reimbursable under government contracts either were not allowable
or not allocated in accordance with federal procurement regulations. The
Company is actively working with the government to resolve these issues.
Management has provided for the potential effect of disallowed costs for the
periods currently under audit and for periods not yet audited, although the
amounts at issue have not been quantified by the government or the Company.
This provision will be reviewed periodically as discussions with the
government progress. Based on the information currently available, management
believes the potential effects of these pending audits will not have a
material adverse effect on the Company's financial position, results of
operations, or cash flows.
 
NOTE G--UNUSUAL ITEMS
 
  During the ten months ended December 31, 1995, the Company recorded $0.5
million in additional income (net), consisting of the following unusual items:
income in settlement of litigation against the IRS, associated with an
affiliate of an acquired company, net of an accrual for related expenses ($6.8
million); a charge to accrue the net settlement cost and legal expenses of
other litigation ($4.6 million); a charge to accrue for severance for the
termination of 110 employees in the engineering and international groups ($1.0
million); and a charge to accrue for consolidation of office space ($0.7
million). During the nine months ended September 30, 1996, the net litigation
income was received and $4.2 million of net settlement costs and legal
expenses were paid. As of September 30, 1996, the Company had substantially
completed its termination of employees in the Company's engineering group and
its consolidation of office space. The termination of employees in several
foreign offices within the international group is approximately 50% complete
as of September 30, 1996 and management expects that all actions will be
completed by December 31, 1996. As of September 30, 1996, a $0.1 million
accrual remains outstanding associated with the termination of employees in
the international group.

NOTE H--GUARANTOR SUBSIDIARIES
 
  In connection with the registration of 12% Senior Notes due 2003, Series B
(Exchange Notes), the Company is required to provide financial information for
four wholly owned subsidiaries of ICF Kaiser International, Inc. (Subsidiary
Guarantors). The Subsidiary Guarantors unconditionally guarantee the payment
of the principal, premium, if any, and interest on the Company's $15 million
of 12% Senior Notes due 2003, Series A issued in December 1996 (Series A
Notes) and the Exchange Notes. The Company is offering to exchange the
Exchange Notes for the Series A Notes. The Subsidiary Guarantors are Cygna
Consulting Engineers and Project Management, Inc., ICF Kaiser Government
Programs, Inc., PCI Operating Company, Inc., and Systems Applications
International, Inc.
 
  Presented below is condensed consolidating financial information for ICF
Kaiser International, Inc. (Parent Company), the Subsidiary Guarantors, and
the non-guarantor subsidiaries as of and for the nine months ended September
30, 1996.
 
  Investments in subsidiaries have been presented using the equity method of
accounting. ICF Kaiser International, Inc. does not have a formal tax sharing
arrangement with its subsidiaries and has allocated taxes to its subsidiaries
based on the Company's effective tax rate. In the Company's opinion, separate
financial statements for Subsidiary Guarantors would not provide additional
information that is material to investors. Therefore, the Subsidiary
Guarantors are combined in the presentation below.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders
ICF Kaiser International, Inc.
 
  We have audited the consolidated balance sheets of ICF Kaiser International,
Inc. and subsidiaries as of December 31, 1995 and February 28, 1995, and the
related consolidated statements of operations, shareholders' equity and cash
flows for the ten months ended December 31, 1995 and the years ended February
28, 1995 and 1994 and the related financial statement Schedule II, Valuation
and Qualifying Accounts. These financial statements and financial statement
schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of ICF Kaiser
International, Inc. and subsidiaries as of December 31, 1995 and February 28,
1995, and the consolidated results of their operations and their cash flows
for the ten months ended December 31, 1995, and for each of the two years in
the period ended February 28, 1995, in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement
schedule referred to above, when considered in relation to the basic
consolidated financial statements taken as a whole, presents fairly, in all
material respects, the information required to be included therein.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A--ORGANIZATION AND NATURE OF OPERATIONS
 
  ICF Kaiser International, Inc. (ICF Kaiser or the Company) was formed on
October 19, 1987, as a holding company for the ICF Kaiser family of companies
developed and acquired. These companies provide engineering, construction,
program management, and consulting services primarily to the public and
private environmental, infrastructure, industry, and energy markets
domestically and internationally.
 
NOTE B--SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation: The consolidated financial statements include
all subsidiaries (including Kaiser-Hill Company, LLC, effective July 1, 1995)
that are controlled by ICF Kaiser. Certain of ICF Kaiser's subsidiaries are
partially owned by outside parties. For financial reporting purposes, the
assets, liabilities, results of operations, and cash flows of these
subsidiaries are included in ICF Kaiser's consolidated financial statements
and the outside parties' interests are reflected as minority interests.
Investments in unconsolidated joint ventures and affiliated companies are
accounted for using the equity method. The difference between the carrying
value of investments accounted for under the equity method and the Company's
underlying equity is amortized on a straight-line basis over the lives of the
underlying assets. All significant intercompany balances and transactions have
been eliminated.
 
  Significant Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  Change in Fiscal Year: The Company changed from a fiscal year ending
February 28 to a fiscal year ending December 31, effective December 31, 1995.
As a result, the accompanying financial statements include consolidated
operations for the ten months ended December 31, 1995 and for the years ended
February 28, 1995 and 1994.
 
  Revenue Recognition: Revenue is recorded on cost-type contracts as costs are
incurred. Revenue on time-and-materials contracts is recognized to the extent
of billable rates times hours delivered plus materials expense incurred.
Revenue on long-term, fixed-price contracts is recognized generally using the
percentage-of-completion method and, therefore, includes a proportion of
expected earnings based on costs incurred to total estimated costs.
 
  Foreign Currency Translation: Results of operations for foreign entities are
translated using the average exchange rates during the period. Assets and
liabilities are translated to U.S. dollars using the exchange rate in effect
at the balance sheet date. Resulting translation adjustments are reflected in
shareholders' equity as cumulative translation adjustment.
 
  Cash Equivalents and Restricted Cash: ICF Kaiser considers all highly liquid
financial instruments purchased with original maturities of three months or
less to be cash equivalents. Other assets as of December 31, 1995 and February
28, 1995 included $600,000 of restricted cash and short-term investments,
which supported a letter of credit for one of ICF Kaiser's subsidiaries.
 
  Fixed Assets: Furniture and equipment are carried at cost, or fair value at
acquisition if acquired through a purchase of a business, and are depreciated
using the straight-line method over their estimated useful lives ranging from
three to ten years. Leasehold improvements are carried at cost and are
amortized using the straight-line method over the remaining lease term.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Goodwill: Goodwill represents the excess of cost over the fair value of the
net assets of acquired businesses and is amortized using the straight-line
method over periods ranging from five to 40 years. The Company evaluates the
recoverability of goodwill on an annual basis by examining undiscounted
operating income. Accumulated amortization was $12,785,000 and $11,148,000 at
December 31, 1995 and February 28, 1995, respectively.
 
  Income Taxes: The Company provides for deferred income taxes using the
liability method on temporary differences between financial reporting and
income tax reporting, which primarily relate to reserves for adjustments and
allowances. If necessary, management records a valuation allowance for
deferred tax assets. The most significant permanent differences between book
and taxable income are nondeductible goodwill amortization, minority interest
earnings of a consolidated subsidiary, the effect of foreign taxes, and
differences between the book and tax basis of businesses sold.
 
  Income taxes have not been provided for the undistributed earnings of the
Company's foreign subsidiaries, because the Company intends to continue the
operations and reinvest the undistributed earnings indefinitely. Undistributed
earnings of foreign subsidiaries for which income taxes have not been provided
amounted to approximately $5.7 million at December 31, 1995.
 
  Net Income (Loss) Per Common Share: Net income (loss) per common share is
computed using net income (loss) available for common shareholders, as
adjusted under the modified treasury stock method, and the weighted average
number of common stock and common stock equivalents outstanding during the
periods presented. Common stock equivalents include stock options and warrants
and additional shares which will be or may be issued in connection with
acquisitions. The adjustments required by the modified treasury stock method
and for acquisition-related contingencies were anti-dilutive for all loss
periods presented and immaterial to the income period presented. Therefore,
the adjustments were excluded from earnings per share computations.
 
  Concentrations of Credit Risk: The Company maintains cash balances primarily
in overnight Eurodollar deposits, investment-grade commercial paper, bank
certificates of deposit, and U.S. government securities. ICF Kaiser grants
uncollateralized credit to its customers. Approximately 64% of ICF Kaiser's
contract receivables at December 31, 1995 are from the U.S. government (see
Note D). When practical and in order to mitigate its credit risk to commercial
customers, ICF Kaiser obtains advance funding of costs for industrial
construction work.
 
  Long-Lived Assets: The Financial Accounting Standards Board (FASB) recently
issued Statement of Financial Accounting Standards No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of", effective for financial statements for fiscal years beginning after
December 15, 1995. It is the Company's current policy to evaluate all long-
lived assets on a periodic basis for asset impairment. Therefore, upon formal
adoption of this statement in 1996, management does not expect that there will
be a material adverse effect on the Company's financial position or
operations.
 
  Stock-Based Compensation: The FASB also recently issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS No. 123), which encourages companies to adopt a fair value
method of accounting for employee stock options and similar equity
instruments. The fair value method requires compensation cost to be measured
at the grant date based on the value of the award and is recognized over the
service period. Alternatively, SFAS No. 123 requires the provision of pro
forma disclosures of net income and earnings per share as if the fair value
method had been adopted when the fair value method is not reflected in the
financial statements. The Company has not yet determined whether it will adopt
a fair value method of accounting for stock-based compensation or provide pro
forma disclosures. The impact of the adoption of this statement on the
financial statements cannot be reasonably estimated at this time. The
requirements of SFAS No. 123 are effective for financial statements for fiscal
years beginning after December 15, 1995.

NOTE C--DIVESTITURES
 
  The Company sold a 20% interest in a subsidiary during the year ended
February 28, 1995, resulting in a $551,000 pretax gain. During the year ended
February 28, 1994, ICF Kaiser sold a portion of its energy engineering
business, resulting in a $925,000 pretax loss.

</TABLE>
 
  U.S. government receivables arise from U.S. government prime contracts and
subcontracts. The significant increase in the unbilled U.S. government
receivables is due primarily to a contract between the U.S. Department of
Energy (DOE) and Kaiser-Hill Company, LLC (Kaiser-Hill) to perform services at
DOE's Rocky Flats Environmental Technology Site in Colorado. Unbilled
receivables result from revenue that has been earned but was not billed as of
the end of the period. The unbilled receivables can be invoiced at
contractually defined intervals and milestones, as well as upon completion of
the contract or the federal government cost audit. Generally, retention is not
expected to be realized within one year; consistent with industry practice,
these receivables are classified as current. Management anticipates that the
remaining unbilled receivables will be substantially billed and collected
within one year.

  Scheduled maturities of long-term debt outstanding at December 31, 1995, are

December 31, 1998, and additional warrants may be issued under certain anti-
dilution provisions. Of the net issue price of

$121,487,500 ($125,000,000 less a $3,512,500 discount), $900,000 was allocated
to the value of the 600,000 warrants and $120,587,500 to the 12% Notes. The
net proceeds were used, in part, to retire the Company's 13.5% Senior
Subordinated Notes due 1999 (13.5% Notes), to repurchase preferred stock, to
repay the outstanding balance on the Company's then-existing revolving credit
facility, and to repurchase warrants associated with the 13.5% Notes and
preferred stock. The recapitalization resulted in a $6.0 million extraordinary
charge (net of $0 tax benefit due to the unanticipated decline in fiscal
1994's fourth-quarter results) for the early extinguishment of debt and a $1.9
million charge to net income available for common shareholders to repurchase
the Series 2C Senior Preferred Stock. In November 1995, the Company's
insurance subsidiary repurchased 1,450 of the Units for $1.4 million. In March
1996, the interest rate on the 12% Notes was increased by one percent until
the Company achieves and maintains a specified level of earnings (see Note I).
 
  The Company's obligations under the 12% Notes are subordinate to its
obligations under the Company's revolving credit facility. Interest payments
are due semiannually. The 12% Notes may not be prepaid at the Company's option
prior to December 31, 1998. Subsequent to that date, the Company may prepay
the 12% Notes at a premium. In addition, the Company agreed to certain
business and financial covenants, including restrictions on indebtedness,
dividends, acquisitions, and certain types of investments and asset sales. At
December 31, 1995, the fair value of the 12% Notes was approximately $116.4
million. The fair value was computed using an average of recently quoted
market prices obtained from financial institutions. Net debt issuance costs of
$3.8 million and $4.2 million associated with the 12% Notes are classified as
other assets at December 31, 1995 and February 28, 1995, respectively, in the
accompanying balance sheets. These costs and the discount on the 12% Notes are
being amortized over the life of the notes.
 
  The Company has a $60 million revolving credit facility (the Credit
Facility) provided by a consortium of banks (the Banks). ICF Kaiser
International, Inc. and certain of its subsidiaries, which are guarantors of
the Credit Facility, granted the Banks a security interest in their accounts
receivable and certain other assets. The Credit Facility limits the payment of
cash dividends, requires the maintenance of specified financial ratios, and
has a $20 million limitation on cash borrowings. Total available credit is
determined from a borrowing base calculation based on accounts receivable. ICF
Kaiser and the Banks entered into amendments in 1995 that modified financial
ratios and other terms of the Credit Facility. As of December 31, 1995, there
were $5.0 million in borrowings outstanding under the Credit Facility, in
addition to letters of credit, and the Company had $23.5 million of available
credit under the Credit Facility. The Credit Facility contains Eurodollar and
alternate base interest rate alternatives with margins dependent upon the
Company's financial operating results, and expires on October 31, 1996. The
outstanding letters of credit were $7.1 million at December 31, 1995, and
issued principally to support performance guarantees under certain contracts.
 
  One of the Company's subsidiaries has a $50 million receivables purchase
facility to support the working capital requirements of the subsidiary under
its contract. The receivables purchase facility requires the subsidiary to
maintain a specified tangible net worth and contains certain default
provisions for delinquent receivables. Program fees consist of 0.30% per annum
of the unused portion of the facility and 0.45% per annum of the used portion
of the facility. The receivables purchase facility is non-recourse to ICF
Kaiser International, Inc. and expires on June 30, 1998.
 
  There are 275,088 common stock warrants that were issued with the 13.5%
Notes that remained outstanding following the repurchase of the other warrants
in January 1994. The warrants expire on May 15, 1999, and are exercisable at
any time for shares of ICF Kaiser Common Stock at $6.87 per share. Additional
warrants may be required to be issued under certain anti-dilution provisions.

NOTE G--CONTINGENCIES
 
  In the course of the Company's normal business activities, various claims or
charges have been asserted and litigation commenced against the Company
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 the Company in such litigation.
 
  The Company 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. The Company 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 the Company by these agencies. Management
does not believe that there will be any material adverse effect on the
Company's financial position, operations, or cash flows as a result of these
investigations.
 
  The Company has a substantial number of cost-reimbursement contracts with
the U.S. government, the costs of which are subject to audit by the U.S.
government. As a result of such audits, the government asserts, from time to
time, that certain costs claimed as reimbursable under government contracts
either were not allowable or not allocated in accordance with federal
procurement regulations. Management believes that the potential effect of
disallowed costs, if any, for the periods currently under audit and for
periods not yet audited, has been provided for adequately and will not have a
material adverse effect on the Company's financial position, operations, or
cash flows.

  Because of the reported losses for the year ended February 28, 1994, a $3.3
million valuation allowance was established in that year for deferred tax
assets. Although the level of pretax income has increased

substantially since that period (with a corresponding increase in taxable
income), the Company has maintained the valuation allowance. At December 31,
1995, the Company had deferred tax assets of $0.7 million related to net
operating loss carryforwards, of which $0.5 million expire within the next
five years and $0.2 million expire in 2008. Additionally, the Company has
deferred tax assets of $2.1 million related to tax credit carryforwards, the
majority of which expire in 1998 to 2009. Management believes that the
Company's expected levels of pretax earnings, when adjusted for nondeductible
expenses such as goodwill amortization, will generate sufficient future
taxable income to realize the $11.9 million deferred tax asset (net) within
the next five years.
 
  The effective income tax (benefit) rate varied from the federal statutory
income tax rate because of the following differences:

  One of the Company's consolidated subsidiaries, Kaiser-Hill, is a flow-
through entity for tax purposes and is partially owned by an outside party.
Accordingly, the provision for income taxes in the accompanying financial
statements was computed based on the Company's taxable share of Kaiser-Hill's
income. The tax rate effect of the outside party's share of income is
reflected above as minority interest earnings of a consolidated subsidiary.
Kaiser-Hill began operations during the ten months ended December 31, 1995.
 
  The tax provision for the year ended February 28, 1995 reflects the deemed
dividend from the repatriation of overseas funds to the United States that
currently could not be offset by foreign tax credits. For the past several
years, the Company has had ongoing negotiations, filings, and litigation with
the Internal Revenue Service (IRS) related to settlement of its tax
liabilities and the liabilities associated with affiliates of acquired
companies. During the year ended February 28, 1995, ICF Kaiser's 1989-1992 tax
returns were accepted as filed, resulting in the receipt of refunds from the
IRS with interest. An agreement also was reached with the IRS as to the amount
of interest owed in connection with previously settled years (1977-1986). The
overall impact on pretax earnings for the year ended February 28, 1995 was a
reduction of net interest expense of $1.3 million related to interest refunds.

  Series 2D Senior Preferred Stock: The Series 2D Senior Preferred Stock
(Series 2D Preferred Stock) together with five-year detachable warrants
(Series 2D Warrants) were issued in fiscal 1992 for a price of $20,000,000
(less a discount of $100,000). Of the net price of $19,900,000, $400,000 was
allocated to the value of the warrants and $19,500,000 was allocated to the
value of the stock. The value of the Series 2D Preferred Stock was reduced
further by issue costs.
 
  Dividends on the Series 2D Preferred Stock are $9,750 per share per annum,
cumulative. Each of the shares has a liquidation preference of $100,000 ($20
million in the aggregate). The issue carries voting rights equal to 2,380,952
shares of ICF Kaiser Common Stock. The Series 2D Preferred Stock may be
redeemed at ICF Kaiser's option at 106.25% of the original price and is
subject to mandatory redemption at liquidation value on January 13, 1997.
Because of technical limitations on the payment of dividends contained in the
Indenture governing the Company's 12% Notes (see Note F), the Company did not
pay the November 30, 1995 and February 29, 1996 accrued dividends in the
aggregate amount of $975,000. Dividends in arrears at December 31, 1995 were
$487,500. If dividends are in arrears in excess of 100 days or redemption does
not occur in January 1997, the holder of the Series 2D Preferred Stock will
have the exclusive right to elect two additional directors and to prohibit or
limit the Company from taking certain specified extraordinary actions without
the holder's consent. In March 1996, the Company and the holders of the 12%
Notes amended the Indenture to permit payment of all accrued but unpaid
dividends (which were then paid) and all future dividends. As consideration
for this amendment, the interest rate on the 12% Notes was increased by one
percent from March 1996 until the Company achieves and maintains a specified
level of earnings.
 
  The Series 2D Warrants expire in November 1997 and may be exercised for
2,680,952 shares of ICF Kaiser Common Stock at an exercise price of $6.90 per
share. In lieu of exercising the warrants, the holder may, at the holder's
option, require the Company to pay it cash or issue shares of ICF Kaiser's
Common Stock equal to the difference between the current market price of the
Company's common stock and 90% of the warrants' current exercise price. In the
event that the Company cannot make a cash payment to the holder of the
warrants without violating certain covenants contained in the Company's
agreements relating to certain indebtedness, the Company will make such
payment in common stock. Additional warrants may be issued under certain anti-
dilution provisions.
 
  Junior Preferred Stock: The Company has authorized 200 shares of Series 1
Junior Convertible Preferred Stock, par value $0.01 per share, with a
liquidation value of $20,000,000 and 500,000 shares of Series 4 Junior
Preferred Stock, par value $0.01 per share, with a liquidation value of
$500,000. There were no shares issued or outstanding on either series as of
December 31, 1995 and February 28, 1995.

NOTE J--COMMON STOCK
 
  Notes Receivable Related to Common Stock: Notes receivable related to ICF
Kaiser Common Stock pertain to promissory notes from certain current and
former members of senior management in accordance with their compensation
agreements collateralized by shares of ICF Kaiser Common Stock.
 
  Shareholder Rights Plan: The Shareholder Rights Plan (Rights Plan) is
designed to provide the Board of Directors (the Board) with the ability to
negotiate with a person or group that might, in the future, make an
unsolicited attempt to acquire control of ICF Kaiser, whether through the
accumulation of shares in the open market or through a tender offer that does
not offer an adequate price. The Rights Plan provides for one Right (Right)
for each outstanding share of ICF Kaiser Common Stock. Each Right entitles the
holder to purchase 1/100 of a share of Series 4 Junior Preferred Stock at a
purchase price of $50. The Rights generally may cause substantial dilution to
a person or group that attempts to acquire the Company on terms not approved
by the Board. The Rights should not interfere with any merger or other
business combination approved by the Board because the Board may, at its
option, following the acquisition by any person or group of 20% of the
outstanding shares of ICF Kaiser Common Stock, redeem the Rights upon payment
of the redemption price of $0.01 per Right. The Rights are not triggered by
the acquisition of beneficial ownership of more than 20% of ICF Kaiser Common
Stock by the initial holder of the Series 2D Preferred Stock. Unless redeemed
earlier by the Board, unexercised Rights expire on January 13, 2002.
 
  Other: At December 31, 1995, ICF Kaiser was obligated to issue 396,167
shares of the Company's common stock pursuant to an agreement with a former
employee. Accordingly, this liability has been recognized in the accompanying
financial statements. The shares were issued in March 1996. 275,000 of these
shares are being held by the Company pursuant to a pledge agreement as
security for an amount receivable from the former employee.

NOTE M--EMPLOYEE BENEFIT PLANS
 
  ICF Kaiser and certain of its subsidiaries sponsor a number of benefit plans
covering substantially all employees who meet minimum length of service
requirements. These plans include the ICF Kaiser International, Inc.
Retirement Plan (Retirement Plan), a defined-contribution profit sharing plan
that provides for contributions by the Company based on a percentage of
covered compensation; the ICF Kaiser International, Inc. Section 401(k) Plan
(401(k) Plan), a cash or deferred-compensation arrangement that allows
employees to defer portions of their salary, subject to certain limitations;
and the ICF Kaiser International, Inc. Employee Stock Ownership Plan (ESOP)
under which the Company made contributions based on a percentage of covered
compensation. Effective March 1, 1993, the Company made contributions equal to
20% of the first 4% of employee contributions to the 401(k) Plan and 2% of
covered compensation to the ESOP. Effective March 1, 1994, the Company
increased its matching contribution to the 401(k) Plan to 50% of the first 4%
of employee contributions and discontinued contributions to the ESOP. Total
expense for these plans for the ten months ended December 31, 1995 and the
years ended February 28, 1995 and 1994 was $5,711,000, $6,466,000, and
$8,041,000, respectively. As of December 31, 1995, the Retirement Plan, 401(k)
Plan, and ESOP owned 1,036,437, 175,937, and 2,104,240 shares, respectively,
of ICF Kaiser Common Stock.

  Certain of the Company's employees are covered by union-sponsored,
collectively bargained, multi-employer pension plans. Contributions and costs
are determined in accordance with the provisions of negotiated labor contracts
or terms of the plans. Pension expense for these plans was $3,676,000,
$2,525,000, and $2,150,000 for the ten months ended December 31, 1995 and the
years ended February 28, 1995 and 1994, respectively.
 
NOTE N--OTHER POSTRETIREMENT BENEFITS
 
  The Company provides certain postretirement benefits to a limited group of
retirees. The cost of these benefits is funded when paid and limited to a
fixed amount per participant. The Company adopted Statement of Financial
Accounting Standards No. 106, "Employers' Accounting for Postretirement
Benefits Other Than Pensions", as of March 1, 1993, and recorded the
transition obligation on the delayed recognition basis.
 
  The funded status of the plan is as follows (in thousands):

  All service cost related to the participants' benefits was included in the
transition obligation.
 
  The discount rate at both December 31, 1995 and February 28, 1995 was 7%.
The 1995 health care cost trend rate is 5%, effective until 2008 when the cost
will be in excess of the Company's maximum obligation. If the trend rate was
increased by 1% for each year, the APBO as of December 31, 1995 would increase
by approximately 3%. Due to changes in assumptions made, including reductions
in premiums paid by the Company, the APBO was reduced by approximately $1.6
million during the ten months ended December 31, 1995. These reductions in the
APBO will be amortized over the average remaining life expectancy of the
plan's participants.

NOTE P--UNUSUAL ITEMS
 
  During the ten months ended December 31, 1995, the Company recorded $0.5
million in additional income (net), consisting of the following unusual items:
income in settlement of litigation against the IRS, associated with an
affiliate of an acquired company, net of an accrual for related expenses ($6.8
million); a charge to accrue the net settlement cost and legal expenses of
other litigation ($4.6 million); a charge to accrue for severance for the
termination of 110 employees in the engineering and international groups ($1.0
million); and a charge to accrue for consolidation of office space ($0.7
million). As a part of management's continuing efforts to identify areas in
which costs can be reduced, the Company has chosen to terminate a group of
underutilized employees and consolidate office space. Management expects that
all actions associated with the termination of employees and office space
consolidation will be completed by December 31, 1996.
 
  During the year ended February 28, 1994, the Company completed a corporate
reorganization, performed a comprehensive review of its key business lines and
its cost structure, and designed and implemented action plans intended to
return the Company to long-term profitability. As a result, the Company
recorded an $8.7 million pretax charge to cover the cost of downsizing the
work force ($2.5 million), consolidating office space and renegotiating
significant leases ($5.1 million), and restructuring certain international
operations ($1.1 million). All actions have been completed, and there is no
further liability outstanding as of December 31, 1995 associated with this
plan.

NOTE T--GUARANTOR SUBSIDIARIES
 
  In connection with the registration of 12% Senior Notes due 2003, Series B
(Exchange Notes), the Company is required to provide financial information for
four wholly owned subsidiaries of ICF Kaiser International, Inc. (Subsidiary
Guarantors). The Subsidiary Guarantors unconditionally guarantee the payment
of the principal, premium, if any, and interest on the Company's $15 million
of 12% Senior Notes due 2003, Series A issued in December 1996 (Series A
Notes) and the Exchange Notes. The Company is offering to exchange the
Exchange Notes for the Series A Notes. The Subsidiary Guarantors are Cygna
Consulting Engineers and Project Management, Inc., ICF Kaiser Government
Programs, Inc., PCI Operating Company, Inc., and Systems Applications
International, Inc.
 
  Presented below is condensed consolidating financial information for ICF
Kaiser International, Inc. (Parent Company), the Subsidiary Guarantors, and
the non-guarantor subsidiaries as of and for the ten months ended December 31,
1995, and the years ended February 28, 1995 and 1994.
 
  Investments in subsidiaries have been presented using the equity method of
accounting. ICF Kaiser International, Inc. does not have a formal tax sharing
arrangement with its subsidiaries and has allocated taxes to its subsidiaries
based on the Company's effective tax rate. In the Company's opinion, separate
financial statements for Subsidiary Guarantors would not provide additional
information that is material to investors. Therefore, the Subsidiary
Guarantors are combined in the presentation below.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Under the Delaware General Corporation Law ("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 costs the court
deems proper in spite of liability adjudication.
 
  The sections of the Company's Restated Certificate of Incorporation and
Amended and Restated By-laws, and of the Certificates of Incorporation and By-
laws of each of the Subsidiary Guarantors incorporated in the state of
Delaware, 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.
 
  The California General Corporation Law provides for the indemnification of
directors and officers in terms sufficiently broad to indemnify directors of
Cygna Consulting Engineers and Project Management, Inc. ("Cygna") under
certain circumstances from liabilities (including reimbursement for expenses
incurred) arising under the Securities Act. Cygna's Bylaws provide for the
indemnification of directors and officers against monetary damages to the
fullest extent permissible under California law.

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes:
 
    (a)(l) To file, during any period in which offers or sales are being
  made, a post-effective amendment to this registration statement:
 
    (i) To include a prospectus required by section 10(a)(3) of the
  Securities Act of 1933;
 
    (ii) To reflect in the prospectus any facts or event arising after the
  effective date of the registration statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  registration statement. 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 end 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 a 20% change in the maximum aggregate offering
  price set forth in the "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;
 
  (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.
 
  (h) That insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers, and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that
 
                                     II-8
<PAGE>
 
a claim for indemnification against such liabilities (other than the payment
by the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

                                     II-1
<PAGE>
 

contained in this paragraph of this Section 3 shall be construed as limiting,

with the provisions of Section 4 and 5 of this Article II.

     Section 5.    Manner of Giving Notice:
                   ------ -- ------ ------
                   Affidavit of Notice.  Except in special cases where other 
                   --------- -- ------
express provision is made by statute, notice or request of any meeting of 
shareholders shall be given either personally or by first-class mail or 
telegraphic or other written communication, charges prepaid.  Notice to a 
shareholder shall be addressed to the shareholder at the address of that 
shareholder appearing on the books of the corporation or given by the 
shareholder to the corporation for the purpose of notice.  If no such address 
appears on the corporation's books or is given, notice shall be deemed to have
been given if sent to that shareholder by first-class mail or telegraphic or 
other written communication to the corporation's principal executive office, or 
if published at least once in a newspaper of general circulation in the county 
where that office is located.  Notice shall be deemed to have been given at the 
time when delivered personally or deposited in the mail or sent by telegram or 
other means of written communication.

     If any notice addressed to a shareholder at the address of that shareholder
appearing on the books of the corporation is returned to the corporation by the 
United States Postal Service marked to indicate that the United States Postal 
Service is unable to deliver the notice to the shareholder at that address, all 
future notices or reports shall be deemed to have been duly given without 
further mailing if these shall be available to the shareholder on written demand
of the shareholder at the principal executive office of the corporation for a 
period of one year from the date of the giving of the notice.

     An affidavit of the mailing or other means of giving any notice of any 
shareholders' meeting may be executed by the secretary, assistant secretary, or 
any transfer agent of the corporation giving the notice, and shall be filed and 
maintained in the minute book of the corporation.

     Section 6.   Adjourned Meetings and Notice Thereof. Any shareholders' 
                  --------- -------- --- ------ -------
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the vote of a majority of the shares represented at the 
meeting, either present in person or by proxy. In the absence of a quorum no 
other business may be transacted at such meeting, except as stated in Section 8 
of this Article II.

     When any meeting of shareholders, either annual or special, is adjourned to
another time or place, notice need not be given of the adjourned meeting if the 
time and place are announced at a meeting at which the adjournment is taken, 
unless a new record date for the adjourned meeting is fixed, or unless the 
adjournment is for more than forty-five (45) days from the date set for the 
original meeting, in which case the Board of Directors shall set a new record 
date. Notice of any such adjourned meeting shall be given to each shareholder of
record entitled to vote at the adjourned meeting in accordance with the 
provisions of Sections 4 and 5 of this Article II. At any adjourned meeting the
corporation may transact any business which might have been transacted at the 
original meeting.

     Section 7.   Voting. The shareholders entitled to notice of any meeting or 
                  ------
to vote at any such meeting shall be only persons in whose name shares stand on 
the stock records of the corporation on the record date determined in 
accordance with Section 11 of this Article II.

     Voting shall in all cases be subject to the provisions of Chapter 7 of the 
California General Corporation Law and to the following provisions:

     (a)  Subject to clause (g), shares held by an administrator, executor, 
guardian, conservator or custodian may be voted by such holder either in person 
or by proxy, without a transfer of



                                     II-4
<PAGE>
 
such shares into the holder's name; and the shares held by a trustee may only be
voted by the trustee, either in person or by proxy, if the shares are standing 
in the name of the trustee.

     (b)  Shares standing in the name of a receiver may be voted by such 
receiver; and shares held by or under the control of a receiver may be voted by 
such receiver without the transfer thereof into the receiver's name if authority
to do so is contained in the order of the court by which such receiver was 
appointed.

     (c)  Subject to the provisions of Section 705 of the Corporations Code of 
California, and except where otherwise agreed in writing between the parties, a 
shareholder whose shares are pledged shall be entitled to vote such shares until
the shares have been transferred into the name of the pledges, and thereafter 
the pledges shall be entitled to vote the shares so transferred.

     (d)  Shares standing in the name of a minor may be voted and the 
corporation may treat all rights incident thereto as exercisable by the minor, 
in person or by proxy, whether or not the corporation has notice, actual or 
constructive, of the nonage, unless a guardian of the minor's property has been 
appointed and written notice of such appointment given to the corporation.

     (e)  Shares standing in the name of another corporation, domestic or 
foreign, may be voted by such officer, agent or proxy holder as the bylaws of 
such other corporation may prescribe or, in the absence of such provision, as 
the board of directors of such other corporation may determine or, in the 
absence of such determination, by the chairman of the board, president or any 
vice president of such other corporation, or by any other person authorized to 
do so by the board, president or any vice president of such other corporation. 
Shares which are purported to be voted or any proxy purported to be executed in 
the name of a corporation (whether or not any title of the person signing is 
indicated) shall be presumed to be voted or the proxy executed in accordance 
with the provisions of this subdivision, unless the contrary is shown.


                                     II-5

<PAGE>
 
        (f)  Shares of the corporation owned by its subsidiary shall not be 
entitled to vote on any matter.

        (g)  Shares held by the corporation in a fiduciary capacity, and shares 
of the corporation held in a fiduciary capacity by any subsidiary, shall not be 
entitled to vote on any matter, except to the extent that the settlor or 
beneficial owner possesses and exercises a right to vote or to give the 
corporation binding instructions as to how to vote such shares.

        (h)  If shares stand of record in the names of two or more persons, 
whether fiduciaries, members of a partnership, joint tenants, tenants in common,
husband and wife as community property, tenants by the entirety, voting
trustees, persons entitled to vote under a shareholder voting agreement or
otherwise, or if two or more persons (including proxy holders) have the same
fiduciary relationship respecting the same shares, unless the secretary of the
corporation is given written notice to the contrary and is furnished with a copy
of the instrument or order appointing them or creating the relationship wherein
it is so provided, their acts with respect to voting shall have the following
effect:

             (i)     If only one votes, such act binds all;

             (ii)    If more than one vote, the act of the majority so voting 
binds all;

             (iii)   If more than one vote, but the vote is evenly split on any 
particular matter, each faction may vote the securities in question 
proportionately.

If the instrument so filed or the registration of the shares shows that any 
such tenancy is held in unequal interests, a majority or even split for the 
purpose of this section shall be a majority or even split in interest.

        The shareholders' vote may be by voice vote or by ballot; provided, 
however, that any election for directors must be by ballot if demanded by any 
shareholder before the voting has begun.  On any matter other than elections of 
directors, any shareholder may vote part of the shares in favor of the proposal 
and refrain from voting the remaining shares or vote them against the proposal, 
but, if the shareholder fails to specify the number of shares which the 
shareholder is voting 

                                     II-6
<PAGE>
 
affirmatively, it will be conclusively presumed that the shareholder's approving
vote is with respect to all shares that the shareholder is entitled to vote. If 
a quorum is present, the affirmative vote of the majority of the shares 
represented at the meeting and entitled to vote on any matter (other than the 
election of directors) shall be the act of the shareholders, unless the vote of 
a greater number or voting by classes is required by California General 
Corporation Law or by the articles of incorporation.

     At a shareholders' meeting at which directors are to be elected, no 
shareholder shall be entitled to cumulate votes (i.e., cast for any one or more 
candidates a number of votes greater than the number of the shareholder's 
shares) unless the candidates' names have been placed in nomination prior to 
commencement of the voting and a shareholder has given notice prior to 
commencement of the voting of the shareholder's intention to cumulate votes. If 
any shareholder has given such a notice, then every shareholder entitled to 
vote may cumulate votes for candidates in nomination and give one candidate a  
number of votes equal to the number of directors to be elected multiplied by the
number of votes to which that shareholder's shares are entitled, or distribute 
the shareholder's votes on the same principle among any or all of the 
candidates, as the shareholder thinks fit. The candidates receiving the highest 
number of votes, up to the number of directors to be elected, shall be elected.

     Section 8.  Quorum.  The presence in person or by proxy of persons entitled
                 ------
to vote a majority of the voting shares at any meeting shall constitute a quorum
for the transaction of business. The shareholders present at a duly called or 
held meeting at which a quorum is present may continue to do business until 
adjournment, notwithstanding the withdrawal of enough shareholders to leave less
than a quorum, if any action taken (other than adjournment) is approved by at 
least a majority of the shares required to constitute a quorum.

     Section 9.  Waiver of Notice; Consent of Absentees.  The transaction of any
                 ------ -- ------  ------- -- ---------
meeting of shareholders, either annual or special, however called and noticed, 
shall be as valid as though had a meeting duly held after regular call and 
notice, if a quorum be present either in person or by proxy, and if,

                                     II-7
<PAGE>
 
either before or after the meeting, each of the shareholders entitled to vote, 
not present in person or by proxy, signs a written waiver of notice, or a 
consent to the holding of such meeting, or an approval of the minutes thereof. 
All such waivers, consents or approvals shall be filed with the corporate 
records or made a part of the minutes of the meeting. Neither the business to be
transacted at nor the purpose of any regular or special meeting of shareholders 
need be specified in any written waiver of notice except that if action is taken
or proposed to be taken for approval of any of those matters specified in the
second paragraph of Section 4 of this Article II, the waiver of notice or
consent shall State the general nature of the proposal.

     Attendance by a person at a meeting shall also constitute a waiver of 
notice of that meeting, except when the person objects, at the beginning of the 
meeting, to the transaction of any business because the meeting is not lawfully 
called or convened. Attendance at a meeting is not a waiver of any right to 
object to the consideration of matters required by law to be included in 
the notice of the meeting but not so included if that objection is expressly
made at the meeting.

     Section 10.   Shareholder Action By Written Consent Without A Meeting.
                   ----------- ------ -- ------- ------- ------- - -------
Any action which may be taken at any annual or special meeting of shareholders 
may be taken without a meeting and without prior notice, if a consent in 
writing, setting forth the action so taken, is signed by the holders of 
outstanding shares having not less than the minimum number of votes that would 
be necessary to authorize or take that action at a meeting at which all shares 
entitled to vote on that action were present and voted. In the case of election 
of directors, such a consent shall be effective only if signed by the holders of
all outstanding shares entitled to vote for the election of directors; provided,
however, that a director may be elected at any time to fill a vacancy on the 
Board of Directors that has not been filled by the directors, by the written 
consent of the holders of a majority of the outstanding shares entitled to vote 
for the election of directors. All such consents shall be filed with the 
secretary of the corporation and shall be maintained in the corporate records. 
Any shareholder giving a written consent, or the shareholder's proxy holders, 
or a transferee of the
                   

                                     II-8
<PAGE>
 
shares or a personal representative of the shareholder or their respective proxy
holders, may revoke the consent by a writing received by the secretary of the 
corporation before written consents of the number of shares required to 
authorize the proposed action have been filed with the secretary.

     If the consents of all shareholders entitled to vote have not been 
solicited in writing, and if the unanimous written consent of all such 
shareholders shall not have been received, the secretary of the corporation 
shall give prompt notice of the corporate action approved by the shareholders 
without a meeting.  This notice shall be given in the manner specified in 
Section 5 of this Article II.  In the case of approval of a matter listed in the
second paragraph of Section 4 of this Article II (except with respect to 
voluntary dissolution), the notice shall be given at least ten (10) days before 
the consummation of any action authorized by that approval.

     Section 11.     Record Date for Shareholder Notice, Voting and Giving 
                     ------ ---- --- ----------- ------  ------ --- ------
                     Consents.  For purposes of determining the shareholders 
                     --------
entitled to notice of any meeting or to vote or entitled to give consent to 
corporate action without a meeting, the Board of Directors may fix, in advance, 
a record date, which shall not be more than sixty (60) days nor less than ten
(10) days before the date of any such meeting nor more than sixty (60) days
before any such action without a meeting, and in this event only shareholders of
record on the date so fixed are entitled to notice and to vote or to give
consents, as the case may be, notwithstanding any transfer of any shares on the
books of the corporation after the record date, except as otherwise provided in
the California General Corporation Law.

     If the Board of Directors does not so fix a record date:

     (a)  The record date for determining shareholders entitled to notice of or 
to vote at a meeting of shareholders shall be at the close of business on the 
business day next preceding the day on which notice is given or, if notice is 
waived, at the close of business on the business day next preceding the day on 
which the meeting is held.

     (b)  The record date for determining shareholders entitled to give consent 
to corporate action in writing without a meeting,

                                     II-9
<PAGE>
 
(i) when no prior action by the Board has been taken, shall be the day on which 
the first written consent is given; or (ii) when prior action of the Board has 
been taken, shall be at the close of business on the day on which the Board 
adopts the resolution relating to that action, or the sixtieth (60th) day before
the date of such other action, whichever is later.

     A determination of shareholders of record entitled to notice of or to vote 
at a meeting of shareholders shall apply to any adjournment of the meeting 
unless the Board of Directors fixes a new record date for the adjourned meeting,
but the Board of Directors shall fix a new record date if the meeting is
adjourned for more than forty-five (45) days from the date set for the original
meeting.

     Shareholders on the record date are entitled to notice and to vote or to 
receive the dividend, distribution or allotment of rights or to exercise the 
rights, as the case may be, notwithstanding any transfer of any shares on the 
books of the corporation after the record date, except as otherwise provided in 
the articles of incorporation or by agreement.

     Section 12. Voting by Proxy. Every person entitled to vote for directors or
                 ------ -- -----
on any other matter shall have the right to do so either in person or by one or
more agents authorized by a written proxy signed by the person and filed with
the secretary of the corporation. A proxy shall be deemed signed if the
shareholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission, or otherwise) by the shareholder or the
shareholder's attorney in fact. A validly executed proxy which does not state
that it is irrevocable shall continue in full force and effect unless (i)
revoked by the person executing it, before the vote pursuant to that proxy, by a
writing delivered to the corporation stating that the proxy is revoked, or by a
subsequent proxy executed by, or attendance at the meeting and voting in person
by, the person executing the proxy, or (ii) written notice of the death or
incapacity of the maker of that proxy is received by the corporation before the
vote pursuant to that proxy is counted, provided, however, that no proxy shall
be valid after the expiration of eleven (11) months from the date of the proxy,
unless otherwise provided in the proxy. The revocability of a proxy that states
on its face that it is irrevocable shall be governed by the provision of 
Sections 705 (a) and 705 (f) of the Corporations Code of California.

     Section 13.     Form of Proxies or Written Consent for 
                     ---- -- ------- -- ------- ------- --- 
                     Corporations Having 100 or More Shareholders.
                     ------------ ------ --- -- ---- ------------

     (a)  If the corporation has outstanding shares held of record by one 
hundred (100) or more persons but is not subject to the reporting requirements 
of the Securities Exchange Act of 1934, any proxy or form of written consent 
distributed to ten (10) or more shareholders must afford the person voting an 
opportunity to specify a choice among approval, disapproval, or abstention as to
each matter or group of related matters, other than elections of directors or 
officers.

     (b)  For the purpose of determining whether the corporation has outstanding
shares held of record by one hundred (100) or more persons, shares shall be 
deemed to be "held of record" by each person who is identified as the owner of 
such shares on the record of shareholders maintained by or on behalf of the 
corporation, in accordance with Section 605 of the California Corporations Code.

     Section 14.     Inspectors of Election. Before any meeting of shareholders,
                     ---------- -- --------
the Board of Directors may appoint any persons other than nominees for office to
act as inspectors of election at the meeting or its adjournment. If no 
inspectors of election are so appointed, the chairman of the meeting may, and on
the request of any shareholder or a shareholder's proxy shall, appoint 
inspectors of election at the meeting. The number of inspectors shall be either 
one (1) or three (3). If inspectors are appointed at a meeting on the request of
one or more shareholders or proxies, the holders of a majority of shares or 
their proxies present at the meeting shall determine whether one (1) or three 
(3) inspectors are to be appointed. If any person appointed as inspector fails 
to appear or fails or refuses to act, the chairman of the meeting may, and upon 
the request of any shareholder or a shareholder's proxy shall, appoint a person 
to fill that vacancy.

     These inspectors shall:

     (a)  Determine the number of shares outstanding and the voting power of 
each, the shares represented at the meeting, the existence of a quorum, and the 
authenticity, validity and effect of proxies;


                                     II-11

<PAGE>
 
     (b)  Receive votes, ballots or consents;

     (c)  Hear and determine all challenges and questions in any way arising in 
connection with the right to vote;

     (d)  Count and tabulate all votes or consents;

     (e)  Determine when the polls shall close;

     (f)  Determine the result; and

     (g)  Do any other acts that may be proper to conduct the election or vote 
with fairness to all shareholders.

                                  -----------

                                   Directors
                                   ---------

     Section 1.  Powers.  Subject to limitations of the articles of 
                 ------
incorporation, the bylaws, and the General Corporation Law of California as to 
action which shall be authorized or approved by the shareholders, and subject to
the duties of directors as prescribed by the bylaws, all corporate powers shall 
be exercised by or under the authority of, and the business and affairs of the 
corporation shall be controlled by, the Board of Directors.  Without prejudice 
to such general powers, but subject to the same limitations, it is hereby 
expressly declared that the directors shall have the following powers to:

     (a)  Select and remove all the other officers, agents and employees of the 
corporation, prescribe such powers and duties for them as may not be 
inconsistent with law, articles of incorporation or the bylaws, fix their 
compensation, and require from them security for faithful service.

     (b)  Conduct, manage and control the affairs and business of the
corporation, and make such rules and regulations therefor not inconsistent with
law, or with the articles of incorporation or the bylaws, as they may deem best.

     (c)  Fix or change the location of the principal executive office,
principal business office or other offices of the corporation as provided in
Sections 1 and 2 of Article I; designate any place within or without the State
of California for the holding of any shareholders' meeting or meetings; adopt,
make and use a corporate seal, prescribe the forms of certificates of stock, and
alter the form of such seal and such certificates from time to time as in their
judgment they may deem best, provided such seal and such certificates shall at
all times comply with the provisions of law.

     (d)  Authorize the issue of shares of stock of the corporation from time to
time, upon such terms as may be lawful, in consideration of money paid, labor 
done or services actually rendered, debts or securities cancelled, or tangible 
or intangible property actually received, or as a dividend, upon a stock split 
or reverse stock split, reclassification, conversion, or exchange of outstanding
shares into shares of another class or other change affecting outstanding 
shares.

                                     III-1
<PAGE>
 
     (e)  Borrow money and incur indebtedness for the purposes of the 
corporation, and cause to be executed and delivered therefor, in the corporate 
name, promissory notes, bonds, debentures, deeds of trust, mortgages, pledges, 
hypothecations or other evidences of debt and securities therefor.

     (f)  Appoint an executive committee and other committees, and delegate to 
the executive committee any of the powers and authority of the Board of 
Directors in the management of the business and affairs of the corporation, 
except the power to declare dividends and to adopt, amend or repeal bylaws.  
The executive committee shall be composed of two or more directors.

     Section 2.  Number and Qualification of Directors.  The Number of Directors
                 -------------------------------------
shall be not less than one or more than ten.  The definite number of directors 
may be changed, or an indefinite number of directors may be provided, by 
amendment duly adopted by the Board of Directors or the shareholders, to these 
bylaws or to the articles of incorporation; provided, however, that if the 
number of directors is set forth in the articles of incorporation, the number 
may be changed only by an amendment to the articles of incorporation.  Prior to 
the issuance of shares by the corporation, the amendment may be adopted by the 
Board of Directors.  After the issuance of shares, the amendment must be 
approved by the vote or written consent of holders of a majority of the 
outstanding shares entitled to vote; provided however, that an amendment 
reducing the number of directors to a number less than five (5) cannot be 
adopted if the votes cast against its adoption at a meeting, or the shares not 
consenting in the case of action by written consent, are equal to more than 
16 2/3% of the outstanding shares entitled to vote.

     Section 3.  Election and Term of Office, Removal of Directors.  The 
                 -------------------------------------------------
directors shall be elected at each annual meeting of shareholders, but if any 
such annual meeting is not held, or the directors are not elected thereat, the 
directors may be elected at any special meeting of shareholders held for that 
purpose.  Except as provided below in the case of removal of a director, all 
directors shall hold office until the expiration of the term for which elected 
and until their respective successors have been elected and qualified.

                                     III-2
<PAGE>
 
     The holders of a majority of the outstanding shares of stock entitled to 
vote may, at any time, peremptorily terminate the term of office of all or any 
of the directors by vote at a meeting called for such purpose or by a written 
statement filed with the secretary of the corporation or, in his absence, with 
any other officer.  Such removal shall be effective immediately even if 
successors are not elected simultaneously, and the vacancies on the Board of 
Directors resulting therefrom shall be filled only the shareholders.  No 
director may be removed (unless the entire Board is removed) when the votes cast
against removal, or not consenting in writing to such removal, would be 
sufficient to elect such director if voted cumulatively at an election at which 
the same total number of votes were cast (or, if such action is taken by written
consent, all shares entitled to vote were voted) and the entire number of 
directors authorized at the time of the directors's most recent election were 
then being elected.  Votes sufficient to elect such director shall occur when 
the shares that are voted against his removal exceed the quotient arrived at by 
dividing the total number of outstanding shares entitled to vote by one plus the
authorized number of directors.

     When by the provisions of the articles of incorporation the holders of the 
shares of any class or series, voting as a class or series, are entitled to 
elect one or more directors, any director so elected may be removed only by the 
applicable vote of the holders of the shares of that class or series.

     No reduction of the authorized number of directors shall have the effect of
removing any director prior to the expiration of such director's term of 
office.

     A director may be removed from office by the superior court of the proper 
county at the suit (to which the corporation is made a party) of shareholders 
holding at least 10 percent of the number of outstanding shares of any class, in
case of fraudulent or dishonest acts or gross abuse of authority or discretion 
with reference to the corporation and may be barred from reelection for a period
prescribed by the court.

     Section 4.  Vacancies.  Vacancies in the Board of Directors may be filled 
                 ---------
by a majority of the remaining directors, though less than a quorum, or by a 
sole remaining director, except that a vacancy created by the removal of a


                                     III-3
<PAGE>

director by the vote or written consent of the shareholders or by court order
may be filled only by the vote of a majority of the shares entitled to vote 
represented at a duly held meeting at which a quorum is present, or by the 
written consent of holders of a majority of the outstanding shares entitled to 
vote.  Each director so elected shall hold office until the next annual meeting 
of the shareholders and until a successor has been elected and qualified.

     A vacancy or vacancies in the Board of Directors shall be deemed to exist 
in the event of the death, resignation, or removal of any director, or if the 
Board of Directors by resolution declares vacant the office of a director who 
has been declared of unsound mind by an order of court or convicted of a felony,
or if the authorized number of directors is increased, or if the shareholders 
fail, at any meeting of shareholders at which any director or directors are 
elected, to elect the number of directors to be voted for at that meeting.

     The shareholders may elect a director or directors at any time to fill any 
vacancy or vacancies not filled by the directors, but any such election by 
written consent shall require the consent of a majority of the outstanding 
shares entitled to vote.

     Any director may resign effective on giving written notice to the chairman 
of the Board, the president, the secretary, or the Board of Directors, unless 
the notice specifies a later time for that resignation to become effective.  If 
the resignation of a director is effective at a future time, the Board of 
Directors may elect a successor to take office when the resignation becomes 
effective.

     If, after the filling of any vacancy by the directors, the directors then 
in office who have been elected by the shareholders shall constitute less than a
majority of the directors then in office, any holder or holders of an aggregate 
of five percent (5%) or more of the total number of shares at the time 
outstanding having the right to vote for such directors may call a special 
meeting of shareholders to be held to elect the entire Board of Directors.  The 
term of office of any director shall terminate upon such election of a 
successor.

                   ----- -- -------
shall be held at any place within or without the State of California which has
been designated from time to time by resolution of the Board or by written
consent of all members of the Board. In the absence of such designation regular
meetings shall be held at the principal executive office of the corporation.
Special meetings of the Board may be held either at a place within or without
the State of California so designated or if not stated in the notice or if there
is no notice, at the principal executive office. Any meeting, regular or
special, may be held by conference telephone or similar communication equipment,
so long as all directors participating in the meeting can hear one another, and
all such directors shall be deemed to be present in person at the meeting.

     Section 6.    Annual Meeting.  Immediately following each annual meeting 
                   ------ -------
of shareholders, the Board of Directors shall hold a regular meeting for the 
purpose of organization, election of officers, and the transaction of other 
business.  Notice of such meeting is hereby dispensed with.

     Section 7.    Other Regular Meetings.  Other regular meetings of the Board
                   ----- ------- --------
of Directors shall be held without notice at such times and places as set forth
in these bylaws or shall be fixed by duly adopted resolution of the Board;
provided, however, should the day of any such regular meeting fall upon a legal
holiday, then said meeting shall be held at the same time on the next day
thereafter ensuing which is not a legal holiday. Notice of all such regular
meetings of the Board of Directors is hereby dispensed with.

     Section 8.    Special Meetings.  Special meetings of the Board of Directors
                   ------- --------
for any purpose or purposes shall be called at any time by the president or, if
he is absent or unable or refuses to act, by any vice president or by any two
directors.

     Notice of the time and place of special meetings shall be delivered 
personally or by telephone to each director, or sent to each director by 
first-class mail or by other form of written communication, charges prepaid, 
addressed to him


                                     III-5
<PAGE>
 
at his address as it is shown upon the records of the corporation, or if it is
not so shown upon the records of the corporation or is not readily
ascertainable, at the place in which the meetings of the directors are regularly
held. In case such notice is mailed or telegraphed, it shall be deposited in the
United States mail or delivered to the telegraph company in the place in which
the principal executive office of the corporation is located at least four (4)
days prior to the time of the holding of the meeting. In case such notice is
delivered personally as above provided, or by telephone or telegram, it shall be
so delivered at least forty-eight (48) hours prior to the time of the holding of
the meeting. Such mailing, telegraphing or delivery as above provided shall be
due, legal and personal notice to such director. Any oral notice given
personally or by telephone may be communicated either to the director or to a
person at the office of the director who the person giving notice has reason to
believe will promptly communicate it to the director. The notice need not
specify the purpose of the meeting nor the place if the meeting is to be held at
the principal executive office of the corporation.

      Section 9.  Action Without Meeting. Any action required or permitted to 
                  ------ ------- -------
be taken by the Board of Directors at a regular or special meeting pursuant to 
these bylaws or Division 1 of Title 1 of the Corporation Code of California may 
be taken without a meeting if all members of the Board shall individually or 
collectively consent in writing to such action. Such written consent or consents
shall be filed with the minutes of the proceedings of the Board.

      Section 10. Notice of Adjournment. Notice of the time and place of holding
                  ------ -- -----------
an adjourned meeting need not be given, unless the meeting is adjourned for more
than twenty-four (24) hours, in which case notice of the time and place shall be
given before the time of the adjourned meeting, in the manner specified in
Section 8 of this Article III, to the directors who were not present at the time
of the adjournment.

      Section 11. Waiver of Notice. The transactions of any meeting of the Board
                  ------ -- ------
of Directors, however called and noticed or whenever held, shall be as valid as
though had at a meeting duly held after regular call and notice, if a quorum be
present, and if, either before or after the meeting, each of the directors not
present signs a written waiver of notice, or a consent to holding such meeting,
or an approval of the minutes thereof. The waiver of notice or consent


                                     III-6
<PAGE>
 
need not specify the purpose of the meeting. All such waivers, consents, or 
approvals shall be filed with the corporate records or made a part of the 
minutes of the meeting. Notice of a meeting shall also be deemed given to any 
director who attends the meeting without protesting before or at its 
commencement, the lack of notice to that director.

     Section 12.  Quorum.  A majority of the authorized number of directors 
                  ------
shall constitute a quorum for the transaction of business, except to adjourn as
provided in Section 13 of this Article III, or except as provided in the
articles of incorporation. Every act or decision done or made by a majority of
the directors present at a meeting duly held at which a quorum is present shall
be regarded as the act of the Board of Directors, subject to the provisions of
Section 310 of the Corporations Code of California (as to approval of contracts
or transactions in which a director has a direct or indirect material financial
interest), Section 311 of that Code (as to appointment of committees), and
Section 317(e) of that Code (as to indemnification of directors). A meeting at
which a quorum is initially present may continue to transact business
notwithstanding the withdrawal of directors, if any action taken is approved by
at least a majority of the required quorum for that meeting.

     Section 13.  Adjournment. A quorum of the directors may adjourn any 
                  -----------
directors' meeting to meet again at a stated day and hour; provided, however, 
that in the absence of a quorum, a majority of the directors present at any 
directors' meeting, either regular or special, may adjourn, from time to time 
until the time fixed for the next regular meeting of the Board.

     Section 14.  Fees and Compensation of Directors. Directors and members of 
                  ---- --- ------------ -- ---------
committees may receive such compensation, if any, for their services, and such 
reimbursement of expenses, as may be fixed or determined by resolution of the 
Board of Directors. This Section 14 shall not be construed to preclude any 
director from serving the corporation in any other capacity as an officer, 
agent, employee, or otherwise, and receiving compensation for those services.

     Section 15.  Committees of Directors; Procedure. The Board of Directors
                  ---------- -- ---------- ---------
may, by resolution adopted by a majority of

                                     III-7
<PAGE>
 
the authorized number of directors, designate one or more committees, each 
consisting of two or more directors, to serve at the pleasure of the Board.  The
Board may designate one or more directors as alternate members of any committee,
who may replace any absent member at any meeting of the committee.  Any 
committee, to the extent provided in the resolution of the Board, shall have all
the authority of the Board, except with respect to:

        (a)  the approval of any action which, under the General Corporation Law
of California, also requires shareholders' approval or approval of the 
outstanding shares;

        (b)  the filling of vacancies in the Board of Directors or in any 
committee;

        (c)  the fixing of compensation of the directors for serving on the 
Board or on any committee;

        (d)  the amendment or repeal of bylaws or the adoption of new bylaws;

        (e)  the amendment or repeal of any resolution of the Board of Directors
which by its express terms is not so amendable or repealable;

        (f)  a distribution to the shareholders of the corporation, except at a 
rate or in a periodic amount or within a price range determined by the Board of 
Directors; or

        (g)  the appointment of any other committees of the Board of Directors 
or the members of these committees.

        Meetings and actions of committees shall be governed by, held and taken
in accordance with, the provisions of Article III of these bylaws, Sections 5
(place of meetings), 7 (regular meetings), 8 (special meetings and notice), 9
(action without meeting), 10 (notice of adjournment), 11 (waiver of notice), 12
(quorum), and 13 (adjournment), with such changes in the context of those bylaws
as are necessary to substitute the committee and its members for the Board of
Directors and its members, except that the time of regular meetings of
committees may be determined either by resolution of the Board of Directors or
by resolution of the committee; special meetings of committees may also be
called by resolution of the Board of Directors; and notice of special meetings
of committees shall also be given to all alternate members, who shall have the
right to attend all meetings of the committee. The Board of Directors may adopt
rules for the government of any committee not inconsistent with the provisions
of these bylaws.

Section 8.01.   Indemnification of Directors and Officers for Actions, Suits,

To the full extent permitted by law, the Corporation shall indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
Corporation), by reason of the fact that he or she is or was or has agreed to
become a director or officer of the Corporation or is or was serving or has
agreed to serve at the request of the Corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise
(including employee benefit plans), or by reason of any action alleged to have
been taken or omitted in such capacity, against costs, charges, expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him or her on his or her behalf in
connection with any threatened, pending or completed action, suit or proceeding
and any appeal therefrom, including but not limited to liability and expenses
incurred on account of profits realized by him or her in the purchase or sale of
securities of the Corporation, if and only if he or she acted in good faith and
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful;
the termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he or she reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his or her
conduct was unlawful.

Section 8.02.   Indemnification of Directors and Officers for Actions or Suits
                By or In the Right of the Corporation.

To the full extent permitted by law, the Corporation shall indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that he or she is or was
or has agreed to become a director or officer of the Corporation or is or was
serving or has agreed to serve at the request of the Corporation as a director
or officer of another corporation, partnership, joint venture, trust or other
enterprise (including employee benefit plans), or by reason of any action
alleged to have been taken or omitted in such capacity, against costs, charges
and expenses (including attorneys' fees) actually and reasonably incurred by him
or her on his or her behalf in connection with the defense or settlement of any
threatened, pending or completed action or suit and any appeal therefrom, or the
defense or settlement of any claim, issue or matter, if and only if he or she
acted in good faith and in a manner he or she reasonably believed to be in or
not opposed to the best interests of the Corporation except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery of Delaware or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of such liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such costs, charges and expenses which the Court of Chancery or
such other court shall deem proper.

Section 8.03.   Indemnification of Others for Actions, Suits, or Proceedings
                Other Than By or In the Right of the Corporation.

investigative (other than an action by or in the right of the Corporation), by
reason of the fact that he or she is or was or has agreed to become an employee,
agent or contractor of the Corporation, or is or was serving or

the Board of Directors of the Corporation, may indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he or she is or was or has
agreed to become an employee, agent or contractor of the Corporation, or is or
was serving or has agreed to serve at the request of the Corporation as a
director, officer, employee, agent or contractor of another corporation,
partnership, joint venture, trust or other enterprise (including employee
benefit plans), or by reason of any action alleged to have been taken or omitted
in such capacity, against costs, charges and expenses (including attorneys'
fees) actually and reasonably incurred by him or her or on his or her behalf in
connection with the defense or settlement of any threatened, pending or
completed action or suit and any appeal therefrom, or the defense or settlement
of any claim, issue or matter, if and only if he or she acted in good faith and
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the Corporation except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery of Delaware or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of such
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such costs, charges and expenses
which the Court of Chancery or such other court shall deem proper.

Section 8.05.   Indemnification for Costs, Charges and Expenses of Successful
                Party.

Notwithstanding the other provisions of this Certificate, to the extent that a
director or officer of the Corporation or other person indemnified under
Sections 9.01 through 9.04, herein, has been successful on the merits or
otherwise, including, without limitation, the dismissal of an action without
prejudice, in defense of any action, suit or proceeding referred to above, or in
defense of any claim, issue or matter therein, he or she shall be indemnified
against all costs, charges and expenses (including attorneys' fees) actually and
reasonably incurred by him or her or on his or her behalf in connection
therewith.

Section 8.06.   Determination of Right to Indemnification.

Unless otherwise ordered by a court, any indemnification under Sections 9.01
through 9.04, herein, shall be paid by the Corporation unless a determination is
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (ii) if
such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by

                                            ICF Kaiser Government Programs, Inc.
                                                                          Page 4

independent legal counsel in a written opinion, or (iii) by the stockholders,
that indemnification of an individual entitled to indemnification under Sections
9.01 through 9.04, herein, is not proper in the circumstances because he or she
has not met the applicable standard of conduct set forth in Sections 9.01
through 9.04, herein.

Section 8.07.   Advance Payment of Costs, Charges and Expenses.

To the full extent permitted by law, the Corporation shall, upon request, pay
costs, charges and expenses (including attorneys' fees) incurred by a person
entitled to indemnification pursuant to Sections 9.01 and 9.02, herein, and, if
applicable, pursuant to Sections 9.03 and 9.04, herein, in defending a civil or
criminal action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding; provided, however, that the payment of such costs,
charges and expenses incurred by a director or officer in his or her capacity as
a director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer) in advance of the final
disposition of such action, suit or proceeding shall be made only upon receipt
of an undertaking by or on behalf of the director or officer to repay all
amounts so advanced in the event that it shall ultimately be determined that
such director or officer is not entitled to be indemnified by the Corporation as
authorized in this certificate; such costs, charges and expenses incurred by
other employees, agents and contractors may be so paid upon such terms and
conditions, if any, as the Board of Directors deems appropriate.

Section 8.08.   Procedure for Indemnification.

Any indemnification or advance of costs, charges and expenses provided for in
Sections 9.01 through 9.07, herein, shall be made promptly, and in any event
within sixty days, upon the written request of the person entitled to
indemnification; the right to indemnification or advances as granted by this
Certificate shall be enforceable by a director or officer or other person
indemnified hereunder in any court of competent jurisdiction. If the Corporation
denies such request, in whole or in part, or if no disposition thereof is made
within sixty days, such person's costs, charges and expenses incurred in
connection with successfully establishing his right to indemnification, in whole
or in part, in any such action shall also be indemnified by the Corporation; it
shall be a defense to any such action (other than an action brought to enforce a
claim for the advance of costs, charges and expenses pursuant to Section 9.07,
herein, where the required undertaking, if any, has been received by the
Corporation) that the claimant has not met the standard of conduct set forth in
Sections 9.01 through 9.04, herein. Neither the failure of the Corporation
(including its Board of Directors, its independent legal counsel, and its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in
Sections 9.01 through 9.04, herein, nor the fact that there has been an actual
determination by the Corporation (including its Board of Directors, its
independent legal counsel, and its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the claimant has not met the applicable standard of conduct.

Section 8.09.   Authorization of Corporation Officers.

The proper officers of the Corporation are, and each of them acting without the
other is, authorized to take any action, for and in the name of the Corporation,
which the officer deems necessary or appropriate (as conclusively presumed from
the taking of such action) to carry out and effect the foregoing Sections 9.01
through 9.08.

Section 8.10.   Other Rights; Continuation of Right to Indemnification.

The indemnification and advancement of expenses provided by this Certificate
shall not be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any law
(present or future, common or statutory), by-law, agreement, vote of
stockholders or

disinterested directors or otherwise, both as to action in his or her official
capacity and as to action in another capacity while holding office or while
employed by or acting as an agent for the Corporation, and shall continue as to
a person who has ceased to serve in the capacity making him or her eligible for
indemnification, and shall inure to the benefit of the estate, heirs, executors
and administrators of such person; all rights to indemnification under this
Certificate shall be deemed to be a contract between the Corporation and each
director and officer of the Corporation and, as applicable, any other person
indemnified hereunder who serves or served in such capacity at any time while
this Certificate as well as the relevant provisions of the Delaware General
Corporation Law or any other applicable laws are or were in effect; any repeal
or modification hereof or of such provisions of such law shall not in any way
diminish any rights to indemnification of such director or officer or other
person entitled to indemnification or the obligations of the Corporation arising
hereunder.

Section 8.11.   Savings Clause.

If this Certificate or any portion hereof shall be invalidated on any ground by
any court of competent jurisdiction, then the Corporation shall nevertheless
indemnify each director and officer, and may indemnify any other person entitled
to indemnification, as to costs, charges and expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement with respect to any
action, suit or proceeding, whether civil, criminal, administrative or
investigative, including an action by or in the right of the Corporation, to the
full extent permitted by any applicable portion of this Certificate that shall
not have been invalidated and to the full extent permitted by applicable law. To
the full extent permitted by law, the Corporation may enter into and perform
agreements with persons, including, without limitation, present and former
officers, directors and employees of the Corporation and of companies acquired
by or merged with the Corporation, obligating the Corporation, among other
things, to provide indemnification and advancement of costs, charges and
expenses to such persons in addition to any indemnification or advancement which
may be available to such person under Sections 9.01 through 9.10 of this
Certificate.

Section 8.12.   Insurance.

The Board of Directors may cause the Corporation to purchase and maintain
insurance on behalf of any person who is or was or has agreed to become a
director or officer of the Corporation, or is or was serving at the request of
the Corporation as a director or officer of another corporation, or as its
representative in a partnership, joint venture, trust or other enterprise
(including employee benefit plans), against any liability asserted against such
person and incurred in any such capacity or arising out of such status, whether
or not the Corporation would have the power to indemnify such person.

Section 8.13.   Adoption of By-laws.

The Board of Directors may from time to time adopt By-laws with respect to
indemnification and may amend such By-laws to provide at all times the fullest
indemnification permitted by the General Corporation Law of the State of
Delaware.

Section 9.01.   Settlement of Debts.

Whenever a compromise or arrangement is proposed between this Corporation and
its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of this
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for this Corporation under the provisions of
Section 291 of Title 8 of the Delaware Code or on the application of trustees in
dissolution or of any receiver or receivers appointed for this Corporation under
the provisions of Section 279 of Title 8 of the Delaware Code, order a meeting
of the creditors or class of creditors, and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, to be summoned in such
manner as the said court directs. If a majority in number representing three
fourths in value of the creditors

to any reorganization of this Corporation as a consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization

stockholders or class of stockholders, of this Corporation, as the case may be,

represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time without notice other than announcement at
the meeting (if the adjournment is not for more than thirty days and a new

fixed), until a quorum shall be present or represented.  At such adjourned
meeting at which a quorum shall be present or represented, any business may be

decision of such question.

Section 2.08.  Proxies.  Each stockholder shall at every meeting of the

meeting of the stockholders unless it shall have been filed with the Secretary
of the meeting when required by the inspectors of election.  All questions
regarding the qualification of voters, the validity of proxies and the

would have been entitled to vote upon the action if such meeting were held,
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting, shall consent in writing to such
corporate action being taken.  Prompt

annual meeting of the stockholders, except as provided in Section 3.02, and each
director shall hold office until his successor is elected and accepts office

hold meetings, both regular and special, either within or without the State of
Delaware.  Meetings may be held by means of conference telephone or similar
communications equipment by means of which all persons participating in the

constitute presence in person at such meeting.

Section 3.05.  Annual Meeting.  The first meeting of each newly elected Board of
Directors shall be held immediately following the adjournment of the annual
meeting of stockholders and at the place thereof.  No notice of such meeting
shall be necessary to the directors in order legally to constitute the meeting,

given as hereinafter provided for special meetings of the Board of Directors.

full number of directors shall constitute a quorum for the transaction of
business, and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors.  If a quorum
shall not be present at any meeting of the Board of Directors, the directors
present thereat may adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present.

Section 3.09.  Chairman of the Board.  At its first meeting after each annual
meeting of stockholders, the Board of Directors shall elect from among its
members a Chairman.  The Board of Directors may also choose a Vice Chairman from
among its members.  The Chairman shall preside at all meetings of the Board of
Directors, and shall perform such other duties as the Board may prescribe.  The
Chairman may participate and act in any meeting of the Board of Directors as a
director.  The Vice Chairman, if any, shall act under the direction of the

duties and exercise the powers of the Chairman.  The Chairman and the Vice
Chairman, if any, (i) shall hold their respective offices at the pleasure of the
Board of Directors, and (ii) may be removed with or without cause at any time by
the Board of Directors.  Any vacancy occurring in the office of the Chairman or
Vice Chairman by death, resignation, removal or otherwise shall be filled by the

authorized in the resolution or resolutions providing for the issuance of shares
of stock adopted by the Board of Directors as provided in Section 151(a) of
Title 8, Delaware Code, fix any of the preferences or rights of such shares
relating to dividends, redemption, dissolution, any distribution of assets of
the Corporation or the conversion into, or the exchange of such shares for
shares of any other class or classes or any other series of the same of any
other class or classes of stock of the Corporation.  Such committee or
committees shall have such name or names as may be determined from time to time
by the Board of Directors.  The member or members of any such committee present
at any meeting and not disqualified from voting may, whether or not they
constitute a quorum, unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any absent or disqualified
member.  At meetings of such committees, a majority of the members or alternate
members at any meeting at which there is a quorum shall be the act of the
committee.

their proceedings and report the same to the Board of Directors.

their addresses appearing on the books of the Corporation shall be deemed to be
given at the time when deposited in the United States mail, postage prepaid.  An

authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or

allotment of rights, or to exercise such rights, or to give such consent, as the
case may be notwithstanding any transfer of any stock on the books of the
Corporation after any such record date fixed as aforesaid.

recognize the person registered on its books as the owner of shares to be the
exclusive owner for all purposes including voting and dividends, and the

Proceedings Other Than By Or In The Right of the Corporation.  To the full
extent permitted by law, the Corporation shall indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation) by
reason of the fact that he is or was or has agreed  to become a director or
officer of the Corporation or is or was serving or has agreed to serve at the
request of the Corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise (including employee
benefit plans) or by reason of any action alleged to have been taken or omitted

reasonably incurred by him or on his behalf in connection with any threatened,
pending or completed action, suit or proceeding and any appeal therefrom
including but not limited to liability and expenses incurred on account of
profits realized by him in the purchase or sale of securities of the
Corporation, if and only if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the Corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful; the termination of any action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent shall not, of itself, create a presumption that the
person did not act in good faith and in a manner which he reasonably believed to
be in or not opposed to the best interests of the Corporation, and, with respect
to any criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.

Section 8.02.  Indemnification of Directors and Officers for Actions or Suits By
Or In The Right of the Corporation.  To the full extent permitted by law, the
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or was or has agreed to become a director or officer of the
Corporation, or is or was serving or  has agreed to serve at the request of the
Corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise (including employee benefit plans), or by
reason of any action alleged to have been taken or omitted in such capacity,
against costs, charges and expenses (including attorneys' fees) actually and
reasonably incurred by him or on his behalf in connection with the defense or
settlement of any threatened, pending or completed action or suit and any appeal
therefrom, or the defense or settlement of any claim, issue or matter, if and
only if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Corporation except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery of Delaware or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of such liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such costs, charges and expenses which the Court of Chancery or
such other court shall deem proper.

Section 8.03.  Indemnification of Others for Actions, Suits, or Proceedings
Other Than By Or In The Right of the Corporation.  To the full extent permitted
by law, the Corporation, in the sole discretion of the Board of Directors of the
Corporation, may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Corporation), by reason of the fact that he
is or was or has agreed to become an employee, agent or contractor of the
Corporation, or is  or was serving or has agreed to serve at the request of the
Corporation as a director, officer, employee, agent or contractor of another
corporation, partnership, joint venture, trust or other enterprise (including
employee benefit plans), or by reason of any action alleged to have been taken
or omitted in such capacity, against costs, charges, expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with any threatened,
pending or completed action, suit or proceeding and any appeal therefrom,
including but not limited to liability and expenses incurred on account of
profits realized by him in the purchase or sale of securities of the

criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful; the termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

Section 8.04.  Indemnification of Others for Actions or Suits By Or In The Right
of the Corporation.  To the full extent permitted by law, the Corporation, in
the sole discretion of the Board of Directors of the Corporation, may indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he is
or was or has agreed to become an employee, agent  or contractor of the
Corporation, or is or was serving or has agreed to serve at the request of the
Corporation as a director, officer, employee, agent or contractor of another
corporation, partnership, joint venture, trust or other enterprise (including
employee benefit plans), or by reason of any action alleged to have been taken
or omitted in such capacity, against costs, charges and expenses (including
attorneys' fees) actually and reasonably incurred by him or on his behalf in
connection with the defense or settlement of any threatened, pending or
completed action or suit and any appeal therefrom, or the defense or settlement
of any claim, issue or matter, if and only if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Corporation except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery of Delaware or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of such liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such costs, charges and expenses which the
Court of Chancery or such other court shall deem proper.

Section 8.05.  Indemnification for Costs, Charges and Expenses of Successful
Party.  Notwithstanding the other provisions of these By-laws, to the extent
that a director or officer of the Corporation or other person indemnified under
Sections 8.01 through 8.04, herein, has been successful on the merits or
otherwise, including, without limitation, the dismissal of an action without
prejudice, in defense of any action, suit or proceeding referred to above, or in
defense of any claim, issue or matter therein, he shall be indemnified against
all costs, charges and expenses  (including attorneys' fees) actually and
reasonably incurred by him or on his behalf in connection therewith.

Section 8.06.  Determination of Right to Indemnification.  Unless otherwise
ordered by a court, any indemnification under Sections 8.01 through 8.04,
herein, shall be paid by the Corporation unless a determination is made (i) by
the Board of Directors by a majority vote of a quorum consisting of directors
who were not parties to such action, suit or proceeding, or (ii) if such a
quorum is not obtainable, or, even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or
(iii) by the stockholders, that indemnification of an individual entitled to
indemnification under Sections 8.01 through 8.04, herein, is not proper in the
circumstances because he has not met the applicable standard of conduct set
forth in Sections 8.01 through 8.04, herein.

Section 8.07.  Advance Payment of Costs, Charges and Expenses.  To the full
extent permitted by law, the Corporation shall, upon request, pay costs, charges
and expenses (including attorneys' fees)

incurred by a person entitled to indemnification pursuant to Sections 8.01 and
8.02, herein, and, if applicable, pursuant to Sections 8.03 and 8.04, herein, in
defending a civil or criminal action, suit or proceeding in advance of the final
disposition of such action, suit or proceeding; provided, however, that the
payment of such costs, charges and expenses incurred by a director or officer in
his capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer) in
advance of the final disposition of such action, suit or proceeding shall be
made only upon receipt of an undertaking by or on behalf of the director or
officer to repay all amounts so advanced in the event that it shall ultimately
be determined that such director or officer is not entitled to be indemnified by
the Corporation as authorized in these By-laws; such costs, charges and expenses
incurred by other employees, agents and contractors may be so paid upon such
terms and conditions, if any, as the Board of Directors deems appropriate.

Section 8.08.  Procedure for Indemnification.  Any indemnification or advance of
costs, charges and expenses provided for in Sections 8.01 through 8.07, herein,
shall be made promptly, and in any event within sixty (60) days, upon the
written request of the person entitled to indemnification; the right to
indemnification or advances as granted by these By-laws shall be enforceable by
a director or officer or other person indemnified hereunder in any court of
competent jurisdiction.  If the Corporation denies such request, in whole or in
part, or if no disposition thereof is made within sixty (60) days, such person's
costs, charges and expenses incurred in connection with successfully
establishing his right to indemnification, in whole or in part, in any such
action shall also be indemnified by the Corporation; it shall be a defense to
any such action (other than an action brought to enforce a claim for the advance
of costs, charges and expenses pursuant to Section 8.07, herein, where the
required undertaking, if any, has been received by the Corporation) that the
claimant has not met the standard of conduct set forth in Sections 8.01 through
8.04, herein, but the burden of proving such defense shall be on the
Corporation.  Neither the failure of the Corporation (including its Board of
Directors, its independent legal counsel, and its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he has met the applicable
standard of conduct set forth in Sections 8.01 through 8.04, herein, nor the
fact that there has been an actual determination by the Corporation (including
its Board of Directors, its independent legal  counsel, and its stockholders)
that the claimant has not met such applicable standard of conduct, shall be a
defense to the action or create a presumption that the claimant has not met the
applicable standard of conduct.

Section 8.09.  Authorization of Corporation Officers.  The proper officers of
the Corporation are, and each of them acting without the other is, authorized to
take any action, for and in the name of the Corporation, which he deems
necessary or appropriate (as conclusively presumed from the taking of such
action) to carry out and effect the foregoing Sections 8.01 through 8.08.

Section 8.10.  Other Rights; Continuation of Right to Indemnification.  The
indemnification and advancement of expenses provided by these By-laws shall not
be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any law
(present or future, common or statutory), by-law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding office or
while employed by or acting as agent for the Corporation, and shall continue as
to a person who has ceased to serve in the capacity making him eligible for
indemnification, and shall inure to the benefit of the estate, heirs, executors
and administrators of such person; all rights to indemnification under these By-
laws shall be deemed to be a contract

between the Corporation and each director and officer of the Corporation and, as
applicable, any other person indemnified hereunder who serves or served in such
capacity at any time while these By-laws as well as the relevant provisions of
the Delaware General Corporation Law or any other applicable laws are or were in
effect; any repeal or modification hereof or of such provisions of such law
shall not in any way diminish any rights to indemnification of such director or
officer or other person entitled to indemnification or the obligations of the
Corporation arising hereunder.

Section 8.11.  Savings Clause.  If Sections 8.01 through 8.10 of these By-laws
or any portion hereof shall be invalidated on any ground by any court of
competent jurisdiction, then the Corporation shall nevertheless indemnify each
director and officer, and may indemnify any other person entitled to
indemnification, as to costs, charges and expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement with respect to any action, suit
or proceeding, whether civil, criminal, administrative or investigative,
including an action by or in the right of the Corporation, to the full extent
permitted by any applicable portion of these By-laws that shall not have been
invalidated and to the full extent permitted by applicable law.  To the full
extent permitted by law, the Corporation may enter into and perform agreements
with persons, including, without limitation, present and former officers,
directors and employees of the Corporation and of companies acquired by or
merged with the Corporation, obligating the Corporation, among other things, to
provide indemnification and advancement of costs, charges and expenses to such
persons in addition to any indemnification or advancement which may be available
to such person under Sections 8.01 through 8.10 of these By-laws.

Section 8.12.  Insurance.  The Board of Directors may cause the Corporation to
purchase and maintain insurance on behalf of any person who is or was or has
agreed to become a director or officer of the Corporation, or is or was serving
at the request of the Corporation as a director or officer of another
corporation, or as its representative in a partnership, joint venture, trust or
other enterprise (including employee benefit plans) against any liability
asserted against such person and incurred in any such  capacity or arising out
of such status, whether or not the Corporation would have the power to indemnify
such person.

Section 8.13.  Amendment of By-laws.  The Board of Directors may from time to
time adopt further By-laws with respect to indemnification and may amend these
and such By-laws to provide at all times the fullest indemnification permitted
by the General Corporation Law of the State of Delaware.

                                 ARTICLE IX
                                 Amendments

Section 9.01.  Amendment by Stockholders.  These By-laws may be amended by a
majority vote of all the stock issued and outstanding and entitled to vote at
any annual or special meeting of the stockholders, provided notice of intention
to amend shall have been contained in the notice of the meeting.

Section 9.02.  Amendment by Board of Directors.  The Board of Directors by a
majority vote of the whole Board at any meeting may amend these By-laws,
including By-laws adopted by the stockholders, but the stockholders may from
time to time specify particular provisions of the By-laws which shall not be
amended by the Board of Directors.

Unless otherwise ordered by a court, any indemnification under Section 9.01
through 9.04, herein, shall be paid by the Corporation unless a determination is
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (ii) if
such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or (iii) by the stockholders, that indemnification of an individual
entitled to indemnification under Section 9.01 through 9.04, herein, is not
proper in the circumstances because he or she has not met the applicable
standard of conduct set forth in Section 9.01 through 9.04, herein.

Section 9.07.    Advance Payment of Costs, Charges and Expenses.
- ------------     ---------------------------------------------- 

To the full extent permitted by law, the Corporation shall, upon request, pay
costs, charges and expenses (including attorneys' fees) incurred by a person
entitled to indemnification pursuant to Sections 9.01 and 9.02, herein, and, if
applicable, pursuant to Sections 9.03 and 9.04, herein, in defending a civil or
criminal action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding; provided, however, that the payment of such costs,
                            --------  -------                                 
charges and expenses incurred by a director or officer in his or her capacity as
a director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer) in advance of the final
disposition of such action, suit or proceeding shall be made only upon receipt
of an undertaking by or on behalf of the director or officer to repay all
amounts so advanced in the event that it shall ultimately be determined that
such director or officer is not entitled to be indemnified by the Corporation as
authorized in this certificate; such costs, charges and expenses is incurred by

conditions, if any, as the Board of Directors deems appropriate.

Section 9.08.    Procedure of Indemnification.
- ------------     ---------------------------- 

Any indemnification or advance of costs, charges and expenses provided for in
Sections 9.01 through 9.07, herein, shall be made promptly, and in any event
within sixty days, upon the written request of the person  entitled to
indemnification; the right to indemnification or advances as granted by this
Certificate shall be enforceable by a director or officer or other person
indemnified hereunder in any court of competent jurisdiction.  If the
Corporation denies such request, in whole or in part, or if no disposition
thereof is made within sixty days, such person's costs, charges and expenses
incurred in connection with successfully establishing his right to
indemnification, in whole or in part, in any such action shall also be
indemnified by the Corporation; it shall be a defense to any such action (other
than an action brought to enforce a claim for the advance of costs, charges and
expenses pursuant to Section 9.07, herein, where the required undertaking, if
any, has been received by the Corporation) that the claimant has not met the
standard of conduct set forth in Section 9.01 through 9.04, herein.  Neither the
failure of the Corporation (including its Board of Directors, its independent
legal counsel, and its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in Sections 9.01 through 9.04, herein, nor the fact that there has
been an actual determination by the Corporation (including its Board of
Directors, its independent legal counsel, and its stockholders) that the
claimant has not met such applicable standard of conduct, shall be a defense to
the action or create a presumption that the claimant has not met the applicable
standard of conduct.

Section 9.09.    Authorization of Corporation Officers.
- ------------     ------------------------------------- 

The proper officers of the Corporation are, and each of them acting without the
other is, authorized to take any action, for and in the name of the Corporation,
which the officer deems necessary or appropriate (as conclusively presumed from
the taking of such action) to carry out and effect the foregoing Sections 9.01
through 9.08.

Section 9.10.    Other Rights; Continuation of Right to Indemnification.
- ------------     ------------------------------------------------------ 

The indemnification and advancement of expenses provided by this Certificate
shall not be deemed exclusive of any other rights which a person seeking
indemnification nor advancement of expenses may be entitled under any law
(present or future, common or statutory), by-law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
or her official capacity and as to action in another capacity while holding
office or while employed by or acting as an agent for the Corporation, and shall
continue as to a person who has ceased to serve in the capacity making him or
her eligible for indemnification, and shall inure to the benefit of the estate,
heirs, executors and administrators of such person; all rights to
indemnification under this Certificate shall be deemed to be a contract between
the Corporation and each director and officer of the Corporation and, as
applicable, any other person indemnified hereunder who serves or served in such
capacity at any time while this Certificate as well as the relevant provisions
of the Delaware General Corporation Law or any other

                                      -7-

indemnification or the obligations of the Corporation arising hereunder.

Section 9.11.    Savings Clause.
- ------------     -------------- 

If this Certificate or any portion hereof shall be invalidated on any ground by

fees), judgments, fines and amounts paid in settlement with respect to any

that a director or officer of the Corporation or other person indemnified under
Sections 8.01 through 8.04, herein, has been successful on the merits or
otherwise, including, without limitation, the dismissal of an action without
prejudice, in defense of any action, suit or proceeding referred to above, or in
defense of any claim, issue or matter therein, he shall be indemnified against
all costs, charges and expenses (including attorneys' fees) actually and
reasonably incurred by him on or on his behalf in connection therewith.

Section 8.06. Determination of Right to Indemnification.  Unless otherwise
- ------------  -----------------------------------------                   
ordered by a court, any indemnification under Sections 8.01 through 8.04,
herein, shall be paid by the Corporation unless a determination is made (i) by
the Board of Directors by a majority vote of a quorum consisting of directors
who were not parties to such action, suit or proceeding, or (ii) of such

                                     - 11 -
<PAGE>
 
a quorum is not obtainable, or, even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or
(iii) by the stockholders, that indemnification of an individual entitled to
indemnification under Sections 8.01 through 8.04, herein, is not proper in the
circumstances because he has not met the applicable standard of conduct set
forth in Sections 8.01 through 8.04, herein.

Section 8.07. Advance Payment of Costs, Charges and Expenses.  To the full
- ------------  ----------------------------------------------              
extent permitted by law, the Corporation shall, upon request, pay costs, charges
and expenses (including attorneys' fees) incurred by a person entitled to
indemnification pursuant to Sections 8.01 and 8.02, herein, and, if applicable,
pursuant to Sections 8.03 and 8.04, herein, and in defending a civil or criminal
action, suit or proceeding in advance of the final disposition of such action,
suit or proceeding; provided, however, that the payment of such costs, charges
                    --------  -------                                         
and expenses incurred by a director or officer in his capacity as a director or
officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer) in advance of the final disposition of
such action, suit or proceeding shall be made only upon receipt of an
undertaking by or on behalf of the director or officer to repay all amounts so
advanced in the event that it shall ultimately be determined that such director
or officer is not entitled to be indemnified by the Corporation as authorized in
these By-laws; such costs, charges and expenses incurred by other employees,
agents and contractors may be so paid upon such terms and conditions, if any, as
the Board of Directors deems appropriate.

Section 8.08. Procedure for Indemnification.  Any indemnification or advance of
- ------------  -----------------------------                                    
costs, charges and expenses provided for in Sections 8.01 through 8.07, herein,
shall be made promptly, and in any event within sixty (60) days, upon the
written request of the person entitled to indemnification; the right to
indemnification or advances as granted by these By-laws shall be enforceable by
a director or officer or other person indemnified hereunder in any court of
competent jurisdiction.  If the Corporation denies such request, in whole or in
part, or if no disposition thereof is made within sixty (60) days, such person's
costs, charges and expenses incurred in connection with successfully
establishing his right to indemnification, in whole or in part, in any such
action shall also be indemnified by the Corporation; it shall be a defense to
any such action (other than action brought to enforce a claim for the advance of
costs, charges and expenses pursuant to Section 8.07, herein, where the required
undertaking, if any, has been received by the Corporation) that the claimant has
not met the standard of conduct set forth in Sections 8.01 through 8.04, herein,
but the burden of proving such defense shall be on the Corporation.  Neither the
failure of the Corporation (including its Board of Directors; its independent
legal counsel, and its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in Sections 8.01 through 8.04, herein, nor the fact that there has been an
actual determination by the Corporation (including its Board of Directors, its
independent legal counsel, and its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the claimant has not met the applicable standard of conduct.

Section 8.09. Authorization of Corporation Officers.  The proper officers of
- ------------  -------------------------------------                         
the Corporation are, and each of them acting without the other is, authorized to
take any action, for and in the name of the Corporation, which he deems
necessary or appropriate (as conclusively presumed from the taking of such
action) to carry out and effect the foregoing Sections 8.01 through 8.08.

Section 8.10. Other Rights; Continuation of Right to Indemnification.  The
- ------------  ------------------------------------------------------      
indemnification and advancement of expenses provided by these By-laws shall not
be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any law
(present or future, common or statutory), by-law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding office or
while employed by or acting as agent for the Corporation, and shall continue as
to a person who has ceased to serve in the capacity making him eligible for
indemnification, and shall inure to the benefit of the estate, heirs, executors
and administrators of such person; all rights to indemnification under these By-
laws shall be deemed to be a contract between the Corporation and each director
and officer of the Corporation and, as applicable, any other person indemnified
hereunder who serves or served in such capacity at any time while these By-laws
as well as the relevant provisions of the Delaware General Corporation Law or
any other applicable laws are or were in effect; any repeal or modification
hereof or of such provisions of such law shall not in any way diminish any
rights to indemnification of such director or officer or other person entitled
to indemnification or the obligations of the Corporation arising hereunder.

Section 8.11. Savings Clause.  If  Sections 8.01 through 8.10 of these By-laws
- ------------  --------------                                                  
or any portion hereof shall be invalidated on any ground by any court of
competent jurisdiction, then the Corporation shall nevertheless indemnify each
director and officer, and may indemnify any other person entitled to
indemnification, as to costs, charges and expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement with respect to any action, suit
or proceeding, whether civil, criminal, administrative or investigative,
including an action by or in the right of the Corporation, to the full extent
permitted by any applicable portion of these By-laws that shall not have been
invalidated and to the full extent permitted by applicable law.  To the full
extent permitted by law, the Corporation may enter into and perform agreements
with persons, including, without limitation, present and former officers,
directors and employees of the Corporation and of companies acquired by or
merged with the Corporation, obligating the Corporation, among other things, to
provide indemnification and advancement of costs, charges and expenses to such
persons in addition to any indemnification or advancement which may be available
to such person under Sections 8.01 through 8.10 of these By-laws.

Section 8.12. Insurance.  The Board of Directors may cause the Corporation to
- ------------  ---------                                                      
purchase and maintain insurance on behalf of any person who is or was or has
agreed to become a director or officer of the Corporation, or is or was serving
at the request of the Corporation as a director or officer of another
corporation, or as its representative in a partnership, joint venture, trust or
other enterprise (including employee benefit plans) against any liability
asserted against such person and incurred in any such capacity or arising out of
such status, whether or not the Corporation would have the power to indemnify
such person.

time adopt further By-laws with respect to indemnification and may amend these

amended by the Board of Directors

respect to any criminal action or proceeding, had no reasonable cause to believe

conduct was unlawful.

Section 8.04.  Indemnification of Others for Actions or Suits By or In the Right
- ------------   -----------------------------------------------------------------
               of the Corporation.
               ------------------ 

To the full extent permitted by law, the Corporation, in the sole discretion of
the Board of Directors of the Corporation, may indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he or she is or was or has
agreed to become an employee, agent or contractor of the Corporation, or is or
was serving or has agreed to serve at the request of the Corporation as a
director, officer, employee, agent or contractor of another corporation,
partnership, joint venture, trust or other enterprise (including employee
benefit plans), or by reason of any action alleged to have been taken or omitted
in such capacity, against costs, charges and expenses (including attorneys'
fees) actually and reasonably incurred by him or her or on his or her behalf in
connection with the defense or settlement of any threatened, pending or
completed action or suit and any appeal therefrom, or the defense or settlement
of any claim, issue or matter, if and only if he or she acted in good faith and
                                  -----------                                  
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the Corporation except that no indemnification shall be made in
respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery of Delaware or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of such
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such costs, charges and expenses
which the Court of Chancery or such other court shall deem proper.

Section 8.05.  Indemnification for Costs, Charges and Expenses of Successful
- ------------   -------------------------------------------------- ----------
               Party.
               ----- 

Notwithstanding the other provisions of this Certificate, to the extent that a
director or officer of the Corporation or other person indemnified under
Sections 9.01 through 9.04, herein, has been successful on the merits or
otherwise, including, without limitation, the dismissal of an action without
prejudice, in defense of any action, suit or proceeding referred to above, or in
defense of any claim, issue or matter therein, he or she shall be indemnified
against all costs, charges and expenses (including attorneys' fees) actually and
reasonably incurred by him or her or on his or her behalf in connection
therewith.

Section 8.06.  Determination of Right to Indemnification.
- ------------   ----------------------------------------- 

Unless otherwise ordered by a court, any indemnification under Sections 9.01
through 9.04, herein, shall be paid by the Corporation unless a determination is
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (ii) if
such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or (iii) by the stockholders, that indemnification of an individual
entitled to indemnification under Sections 9.01 through 9.04, herein, is not
proper in the circumstances because he or she has not met the applicable
standard of conduct set forth in Sections 9.01 through 9.04, herein.

Section 8.07.  Advance Payment of Costs, Charges and Expenses.
- ------------   ---------------------------------------------- 

To the full extent permitted by law, the Corporation shall, upon request, pay
costs, charges and expenses (including attorneys' fees) incurred by a person
entitled to indemnification pursuant to Sections 9.01 and 9.02, herein, and, if
applicable, pursuant to Sections 9.03 and 9.04, herein, in defending a civil or
criminal action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding; provided, however, that the payment of such costs,
                            --------  -------                                 
charges and expenses incurred by a director or officer in his or her capacity as
a director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer) in advance of the final
<PAGE>
 
                                                Certificate of Incorporation of
                                       Systems Applications International, Inc.

                                                                         Page 4


disposition of such action, suit or proceeding shall be made only upon receipt
of an undertaking by or on behalf of the director or officer to repay all
amounts so advanced in the event that it shall ultimately be determined that
such director or officer is not entitled to be indemnified by the Corporation as
authorized in this certificate; such costs, charges and expenses incurred by
other employees, agents and contractors may be so paid upon such terms and
conditions, if any, as the Board of Directors deems appropriate.

Section 8.08.  Procedure for Indemnification.
- ------------   ----------------------------- 

Any indemnification or advance of costs, charges and expenses provided for in
Sections 9.01 through 9.07, herein, shall be made promptly, and in any event
within sixty days, upon the written request of the person entitled to
indemnification; the right to indemnification or advances as granted by this
Certificate shall be enforceable by a director or officer or other person
indemnified hereunder in any court of competent jurisdiction. If the Corporation
denies such request, in whole or in part, or if no disposition thereof is made
within sixty days, such person's costs, charges and expenses incurred in
connection with successfully establishing his right to indemnification, in whole
or in part, in any such action shall also be indemnified by the Corporation; it
shall be a defense to any such action (other than an action brought to enforce a
claim for the advance of costs, charges and expenses pursuant to Section 9.07,
herein, where the required undertaking, if any, has been received by the
Corporation) that the claimant has not met the standard of conduct set forth in
Sections 9.01 through 9.04, herein. Neither the failure of the Corporation
(including its Board of Directors, its independent legal counsel, and its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in
Sections 9.01 through 9.04, herein, nor the fact that there has been an actual
determination by the Corporation (including its Board of Directors, its
independent legal counsel, and its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the claimant has not met the applicable standard of conduct.

Section 8.09.  Authorization of Corporation Officers.
- ------------   ------------------------------------- 

The proper officers of the Corporation are, and each of them acting without the
other is, authorized to take any action, for and in the name of the Corporation,
which the officer deems necessary or appropriate (as conclusively presumed from
the taking of such action) to carry out and effect the foregoing Sections 9.01
through 9.08.


Section 8.10.  Other Rights; Continuation of Right to Indemnification.
- ------------   ------------------------------------------------------ 

The indemnification and advancement of expenses provided by this Certificate
shall not be deemed exclusive of any other rights to which a person seeking
indemnification or advancement of expenses may be entitled under any law
(present or future, common or statutory), by-law, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
or her official capacity and as to action in another capacity while holding
office or while employed by or acting as an agent for the Corporation, and shall
continue as to a person who has ceased to serve in the capacity making him or
her eligible for indemnification, and shall inure to the benefit of the estate,
heirs, executors and administrators of such person; all rights to
indemnification under this Certificate shall be deemed to be a contract between
the Corporation and each director and officer of the Corporation and, as
applicable, any other person indemnified hereunder who serves or served in such
capacity at any time while this Certificate as well as the relevant provisions
of the Delaware General Corporation Law or any other applicable laws are or were
in effect; any repeal or modification hereof or of such provisions of such law
shall not in any way diminish any rights to indemnification of such director or
officer or other person entitled to indemnification or the obligations of the
Corporation arising hereunder.

Section 8.11.  Savings Clause.
- ------------   -------------- 

If this Certificate or any portion hereof shall be invalidated on any ground by
any court of competent jurisdiction, then the Corporation shall nevertheless
indemnify each director and officer, and may indemnify any other person entitled
to indemnification, as to costs, charges and expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement with respect to any
action, suit or proceeding, whether civil, criminal, administrative or
investigative,

including an action by or in the right of the Corporation, to the full extent
permitted by any applicable portion of this Certificate that shall not have been
invalidated and to the full extent permitted by applicable law. To the full
extent permitted by law, the Corporation may enter into and perform agreements
with persons, including, without limitation, present and former officers,
directors and employees of the Corporation and of companies acquired by or
merged with the Corporation, obligating the Corporation, among other things, to
provide indemnification and advancement of costs, charges and expenses to such
persons in addition to any indemnification or advancement which may be available
to such person under Sections 9.01 through 9.10 of this Certificate.

Section 8.12.  Insurance.
- ------------   --------- 

The Board of Directors may cause the Corporation to purchase and maintain
insurance on behalf of any person who is or was or has agreed to become a
director or officer of the Corporation, or is or was serving at the request of
the Corporation as a director or officer of another corporation, or as its
representative in a partnership, joint venture, trust or other enterprise
(including employee benefit plans), against any liability asserted against such
person and incurred in any such capacity or arising out of such status, whether
or not the Corporation would have the power to indemnify such person.

Section 8.13.  Adoption of By-laws.
- ------------   ------------------- 

The Board of Directors may from time to time adopt By-laws with respect to
indemnification and may amend such By-laws to provide at all times the fullest
indemnification permitted by the General Corporation Law of the State of
Delaware.

Section 9.01.  Settlement of Debts.
- ------------   ------------------- 

Whenever a compromise or arrangement is proposed between this Corporation and
its creditors or any class of them and/or between this Corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of this
Corporation or of any creditor or stockholder thereof or on the application of
any receiver or receivers appointed for this Corporation under the provisions of
Section 291 of Title 8 of the Delaware Code or on the application of trustees in
dissolution or of any receiver or receivers appointed for this Corporation under
the provisions of Section 279 of Title 8 of the Delaware Code, order a meeting
of the creditors or class of creditors, and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, to be summoned in such
manner as the said court directs. If a majority in number representing three
fourths in value of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this Corporation, as the case may be,
agree to any compromise or arrangement and to any reorganization of this
Corporation as a consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of this Corporation, as the case may be, and also on this
Corporation.

to time by the Board of Directors (or duly authorized committee of the Board of
Directors) or in the By-laws of the Corporation.

                           MEETINGS OF STOCKHOLDERS
                           ------------------------

     Section l.  Place of Meetings.  All annual meetings of stock-holders shall
     ----------  ------------------                                            
be held at the office of the Corporation in the City of Oakland, County of 
Alameda, State of California or at any other place which may be designated
either by the Board of Directors, pursuant to authority hereinafter granted to
said Board or by written consent of all stockholders entitled to vote thereat,
given either before or after the meeting and filed with the Secretary of the
Corporation.

     Section 2.  Annual Meetings.  The annual meeting of stockholders shall be 
     ----------  ----------------                                              
held on the first Wednesday following the first Tuesday in October of each year
at 2:30 in the afternoon of said day or at such other time as the stockholders
may agree; provided, however, that should said day fall upon a legal holiday any
year, then the annual meeting of stockholders for such year shall be held at the
same time and place on the next day of such year thereafter ensuing which is not
a legal holiday.

     Not less than ten (10) nor more than sixty (60) days' advance written 
notice of the actual date of each such annual meeting shall be given to each
stockholder entitled to vote thereat in the same manner as is provided in
Section 3 of this Article II for the giving of written notice of special
meetings of stockholders.

     Section 3.  Special Meetings.  Special meetings of stockholders, for any
     ----------  -----------------                                           
purpose or purposes, unless otherwise prescribed by statute, may be called by
the President, and shall be called by the President or Secretary at the request
in writing of a majority of the Board of Directors, or at the request in writing
of stockholders owning not less than one fifth (1/5) of the entire capital stock
of the Corporation issued and outstanding and entitled to vote.  Such request
shall state the purpose or purposes of the proposed meeting.

     Except in special cases where other express provision is made by statute,
written notice of such special meetings shall be given to each stockholder
entitled to vote, either personally or by sending a copy of the notice through
the mail or by telegraph, charges prepaid, to his address appearing on the books
of the Corporation or supplied by him to the Corporation for the purpose of
notice.  If a stockholder supplies no address, notice shall be deemed to have
been given him if mailed to he place where the principal office 
<PAGE>
 
of the Corporation is situated, or published at least once in some newspaper of
general circulation in the county of said principal office. All such notices
shall be sent to each stockholder entitled thereto not less than ten (10) nor
more than sixty (60) days before each special meeting and shall specify the
place, the day and the hour of such meeting, and the general nature of the
business to be transacted.

     Section 4.  Adjourned Meetings and Notice Thereof.  Any stockholders' 
     ----------  -------------------------------------- 
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the vote of a majority of the shares, the holders of which
are either present in person or represented by proxy thereat, but in the absence
of a quorum no other business may be transacted at any such meeting.

     When any stockholders meeting, either annual or special, is adjourned for
thirty (30) days or more, notice of the adjourned meeting shall be given as in
the case of an original meeting. Save as aforesaid, it shall not be necessary to
give any notice of an adjourned meeting or of the business to be transacted at
an adjourned meeting, other than by announcement at the meeting at which such
adjournment is taken.

     Section 5.  Entry of Notice.  Whenever any stockholder entitled to vote has
     ----------  ----------------                                               
been absent from any meeting of stockholders, whether annual or special, an
entry in the minutes to the effect that notice has been duly given shall be
conclusive and incontrovertible evidence that due notice of such meeting was
given to such stockholders, as required by law and by the By-Laws of the
Corporation.

     Section 6.  Voting.  At all meetings of stockholders every stockholder
     ----------  -------                                                   
entitled to vote shall have the right to vote in person or by proxy the number
of shares standing in his own name on the stock records of the Corporation.
Such vote may be viva voce or by ballot; provided, however, that all elections
for Directors must be by ballot upon demand made by a stockholder at any
election and before the voting begins.

     Every stockholder entitled to vote at any election of Directors shall have
the right to cumulate his votes and give one candidate a number of votes equal
to the number of Directors to be elected multiplied by the number of votes to
which his shares are entitled, or to distribute his votes on the same principal
among as many candidates as he shall think fit.  The candidates receiving the
highest number of votes up to the number of Directors to be elected shall be
elected.

     Section 7.  Quorum.  The presence in person or by proxy of the holders of a
     ----------  -------                                                        
majority of the shares entitled to vote at any meeting shall constitute a quorum
for the transaction of business.  The stockholders present at a duly called or
held meeting at which a quorum is present may continue to do business until
adjournment, notwithstanding the withdrawal of enough stockholders to leave less
than a quorum.

     Section 8.  Consent of Absentees.  The transactions of any meetings of
     ----------  ---------------------                                     
stockholders, either annual or special, however called and noticed, shall be as
valid as if transacted at a meeting duly held after regular call and notice, if
a quorum be present either in person or by proxy, and if, either before or after
the meeting, each of the stockholders entitled to vote, not present in person or
by proxy, sign a written waiver of notice, or a consent to the holding of such
meeting, or an approval of the minutes thereof.  All such waivers, consents, or
approvals shall be filed with the corporate records or made a part of the
minutes of the meeting.

     Section 9.  Action Without Meeting.  Any action, except election of 
     ----------  -----------------------   
Directors, which under the provisions of the General Corporation Law of Delaware
may be taken at a meeting of the stockholders, may be taken without a meeting if
authorized by the written consent of stockholders holding at least a majority of
the voting power; provided, if any greater proportion of voting power is
required for such action at a meeting, then such greater proportion of written
consents shall be required.
<PAGE>
 
     Section 10.  Proxies.  Every person entitled to vote or execute consents 
     ---------------------
shall have the right to do so either in person or by an agent or agents
authorized by a written proxy executed by such person or his duly authorized
agent and filed with the Secretary of the Corporation; provided that no such
proxy shall be valid after the expiration of eleven (11) months from the date of
its execution, unless the stockholder executing it specifies therein the length
of time for which such proxy is to continue in force, which is in no case to
exceed seven (7) years from the date of its execution.

     Section l.  Powers.  Subject to limitations of the Certificate of
     ----------  -------                                              
Incorporation, of the By-Laws, and of the Corporation Laws of the State of
Delaware as to action to be authorized or approved by the stockholders, and
subject to the duties of Directors as prescribed by the By-Laws, all corporate
powers shall be exercised by or under the authority of, and the business and
affairs of the Corporation shall be controlled by, the Board of Directors.
Without prejudice to such general powers, but subject to the same limitation, it
is hereby expressly declared that the Directors shall have the following powers,
to wit:

First - To select and remove all the other officers, agents and employees of the
Corporation, prescribe such powers and duties for them as may not be
inconsistent with law, with the Certificate of Incorporation or the By-Laws fix
their compensation, and require from them security for faithful service, and to
appoint committees, with such authority, not inconsistent with law, as may be
set forth in the resolution or resolutions establishing the same.

Corporation, and to make such rules and regulations therefore not inconsistent

best.

without the State of Delaware, and to change such office or offices from one
location to another as provided for in Article I, Section 2, hereof, and by the

require; to designate any place within or without the State of Delaware for the
holding of any stockholder's or Directors' meeting or meetings; and to adopt,
make and use a corporate seal, and to prescribe the forms of Certificates of
stock, and to alter the form of such seal and of such certificates from time to
time, in their judgement they may deem best, provided such seal and such

                                   THE NOTES

Section 2.01    Form and Dating

          The Series A Notes and the Trustee's certificate of authentication
thereof shall be substantially in the form of Exhibit A annexed hereto, which is
hereby incorporated in and expressly made a part of this Indenture.  The Series
B Notes and the Trustee's certificate of authentication thereof shall be
substantially in the form of Exhibit B annexed hereto, which is hereby
incorporated in and expressly made a part of this Indenture.  The Notes may have
notations, legends or endorsements required by law, stock exchange rule or
usage.  The Company and the Trustee shall approve any notation, legend or
endorsement on the Notes.  Each Note shall be dated the date of its
authentication.  The Notes shall be in denominations of $1,000 and integral
multiples thereof.

          Notes offered and sold in reliance on Rule 144A and to Institutional
Accredited Investors shall be issued initially in the form of one or more
permanent Global Notes in registered form, substantially in the form set forth
in Exhibit A, deposited with the Trustee, as custodian for the Depository, and
shall bear the legend set forth on Exhibit C.  The aggregate principal amount of
any Global Note may from time to time be increased or decreased by adjustments
made on the records of the Trustee, as custodian for the Depository, as
hereinafter provided.

          Notes offered and sold in offshore transactions in reliance on
Regulation S shall be issued in the form of certificated Notes in registered
form, substantially in the form set forth in Exhibit A (the "Offshore Physical
Notes").  Notes offered and sold in reliance on any other exemption from
registration under the Securities Act other than as described in the preceding
paragraph shall be issued, and Notes offered and sold in reliance on Rule 144A
may be issued, in the form of certificated Notes in registered form in
substantially the form set forth in Exhibit A (the "U.S. Physical Notes").  The
Offshore Physical Notes and the U.S. Physical Notes are sometimes collectively
herein referred to as the "Physical Notes."

          The terms and provisions contained in the Notes shall constitute, and
are hereby expressly made, a part of this Indenture and to the extent applicable
the Company and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby.

Section 2.02    Execution and Authentication

          Two Officers shall sign the Notes for the Company by manual or
facsimile signature.  The Company's seal shall be reproduced on the Notes and
may be in facsimile form.

          If an Officer whose signature is on a Note no longer holds that office
at the time the Note is authenticated, the Note nevertheless shall be valid.

          A Note shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

          The Trustee shall authenticate (a) Series A Notes for original issue
in the aggregate principal amount not to exceed $15,000,000 and (b) Series B
Notes from time to time for issue only in exchange for a like principal amount
of Series A Notes, in each case upon the receipt of a Company Order.  The
aggregate principal amount of Notes outstanding at any time may not exceed
$15,000,000, except as provided in Section 2.06.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes.  An authenticating agent may authenticate Notes
whenever the Trustee may do so.  Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent.  An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate.

Section 2.03    Registrar and Paying Agent
<PAGE>
 
          The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("Registrar") and an
office or agency where Notes may be presented for payment ("Paying Agent").  The
Registrar shall keep a register of the Notes and of their transfer and exchange.
The Company may appoint one or more co-registrars and one or more additional
paying agents.  The term "Registrar" includes any co-registrar and the term
"Paying Agent" includes any additional paying agent.  The Company may change any
Paying Agent or Registrar without notice to any Holder.  The Company shall
notify the Trustee of the name and address of any Agent not a party to this
Indenture.  If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such.  The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

          Each Note shall be dated the date of its authentication.

Section 2.04    Paying Agent to Hold Money in Trust

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal of, premium, if any, or interest on the Notes, and will notify the
Trustee of any default by the Company in making any such payment.  While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee.  The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee.  Upon payment over to the Trustee,
the Paying Agent (if other than the Company or a Subsidiary) shall have no
further liability for the money.  If the Company or a Subsidiary acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the benefit of
the Holders all money held by it as Paying Agent.

Section 2.05    Registration of Transfer and Exchange

          (a)   Transfer and Exchange of Physical Notes.  When Physical Notes
                ---------------------------------------

(i)       to register the transfer of the Physical Notes; or

(ii)      to exchange such Physical Notes for an equal number of Physical Notes
          of other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if
the requirements under this Indenture as set forth in this Section 2.05 for such
transactions are met; provided, however, that the Physical Notes presented or
surrendered for registration of transfer or exchange:

          (A) shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing; and

Holder for registration in the name of such Holder, without transfer, a
certification from such Holder to that effect (substantially in the form of
Exhibit D hereto); or

         (II) if such Physical Note is being transferred to a Qualified
Institutional Buyer in accordance with Rule 144A, a certification to that effect
(substantially in the form of Exhibit D hereto); or

        (III) if such Physical Note is being transferred to an Institutional
Accredited Investor, delivery of a certification to that effect (substantially
in the form of Exhibit D hereto) and a Transferee Certificate for Institutional
Accredited Investors substantially in the form of Exhibit E hereto; or
<PAGE>
 
         (IV) if such Physical Note is being transferred in reliance on

          (b)   Restrictions on Exchange of a Physical Note for a Beneficial
                ------------------------------------------------------------  
Interest in a Global Note. A Physical Note may not be exchanged for a beneficial
- -------------------------
interest in a Global Note except upon satisfaction of the requirements set forth
below. Upon receipt by the Registrar of a Physical Note, duly endorsed or
accompanied by appropriate instruments of transfer, in form satisfactory to the
Registrar, together with:

          (i)   certification, substantially in the form of Exhibit D hereto,
that such Physical Note is being transferred (A) to a Qualified Institutional
Buyer, (B) to an Accredited Investor or (C) in an offshore transaction in
reliance on Regulation S; and

         (ii)   a Company Order directing the Registrar to make, or to direct
the Depository to make, an endorsement on the applicable Global Note to reflect
an increase in the aggregate amount of the Notes represented by the Global Note,

then the Registrar shall cancel such Physical Note and cause, or direct the
Depository to cause, in accordance with the standing instructions and procedures
existing between the Depository and the Registrar, the principal amount of Notes
represented by the applicable Global Note to be increased accordingly.  If no
Global Note is then outstanding, the Company shall issue and the Trustee shall,
upon a Company Order in accordance with Section 2.02, authenticate such a Global
Note in the appropriate principal amount.

        (c)     Transfer and Exchange of Global Notes.  The transfer and 
                -------------------------------------
exchange of Global Notes or beneficial interests therein shall be effected
through the Depository in accordance with this Indenture (including the
restrictions on transfer set forth herein) and the procedures of the Depository
therefor.

        (d)     Transfer of a Beneficial Interest in a Global Note for a 
                --------------------------------------------------------
Physical Note.
- -------------
        
        (i)     Any Person having a beneficial interest in a Global Note may
upon request exchange such beneficial interest for a Physical Note. Upon receipt
by the Registrar of a Company Order, or such other form of instructions as is
customary for the Depository, from the Depository or its nominee on behalf of
any Person having a beneficial interest in a Global Note and upon receipt by the
Trustee of a written order or such other form of instructions as is customary
for the Depository or the Person designated by the Depository as having such a
beneficial interest containing registration instructions and, in the case of any
such transfer or exchange of a beneficial interest in Notes the offer and sale
of which have not been registered under the Securities Act, the following
additional information and documents:

        (A) if such beneficial interest is being transferred to the Person
designated by the Depository as being the beneficial owner, a certification from
such Person to that effect (substantially in the form of Exhibit D hereto); or

        (B) if such beneficial interest is being transferred to a Qualified
Institutional Buyer in accordance with Rule 144A, a certification to that effect
(substantially in the form of Exhibit D hereto); or
<PAGE>
 
         (C) if such beneficial interest is being transferred to an
Institutional Accredited Investor, delivery of a certification to that effect
(substantially in the form of Exhibit D hereto) and a Certificate for
Institutional Accredited Investors substantially in the form of Exhibit E
hereto; or

         (D) if such beneficial interest is being transferred in reliance on
Regulation S, delivery of a certification to that effect (substantially in the
form of Exhibit D hereto) and a Transferee Certificate for Regulation S
Transfers substantially in the form of Exhibit F hereto and an Opinion of
Counsel reasonably satisfactory to the Company to the effect that such transfer
is in compliance with the Securities Act; or

         (E) if such beneficial interest is being transferred in reliance on
Rule 144 under the Securities Act, delivery of a certification to that effect
(substantially in the form of Exhibit D hereto) and an Opinion of Counsel
reasonably satisfactory to the Company to the effect that such transfer is in
compliance with the Securities Act; or

         (F) if such beneficial interest is being transferred in reliance on
another exemption from the registration requirements of the Securities Act, a
certification to that effect (substantially in the form of Exhibit D hereto) and
an Opinion of Counsel reasonably satisfactory to the Company to the effect that
such transfer is in compliance with the Securities Act,

         then the Registrar will cause, in accordance with the standing
instructions and procedures existing between the Depository and the Registrar,
the aggregate principal amount of the applicable Global Note to be reduced and,
following such reduction, the Company will execute and, upon receipt of an
authentication order in the form of an Officers' Certificate in accordance with
Section 2.02, the Trustee will authenticate and deliver to the transferee a
Physical Note.

         (ii) Notes issued in exchange for a beneficial interest in a Global
Note pursuant to this Section 2.05(d) shall be registered in such names and in
such authorized denominations as the Depository, pursuant to instructions from
its direct or indirect participants or otherwise, shall instruct the Registrar
in writing. The Registrar shall deliver such Physical Notes to the Persons in
whose names such Physical Notes are so registered.

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

         (f) Private Placement Legend. Upon the transfer, exchange or
             ------------------------
replacement of Notes not bearing the Private Placement Legend, the Registrar
shall deliver Notes that do not bear the Private Placement Legend. Upon the
transfer, exchange or replacement of Notes bearing the private Placement Legend,
the Registrar shall deliver only Notes that bear the Private Placement Legend
unless, and the Trustee is hereby authorized to deliver Notes without the
Private Placement Legend if, (i) there is delivered to the Trustee an Opinion of
Counsel reasonably satisfactory to the Company and the Trustee to the effect
that neither such legend nor the related restrictions on transfer are required
in order to maintain compliance with the provisions of the Securities Act or
(ii) such Note has been sold pursuant to an effective registration statement
under the Securities Act.

         (g) General. By its acceptance of any Note bearing the Private
             -------
Placement Legend, each Holder of such a Note acknowledges the restrictions on
transfer of such Note set forth in this Indenture and in the Private Placement
Legend and agrees that it will transfer such Note only as provided in this
Indenture.

         The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.13 or this Section 2.05.
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 Registrar.

         No service charge shall be made to a Holder for any registration of
transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any transfer tax or
<PAGE>
 
similar governmental charge payable in connection therewith (other than such
transfer tax or similar governmental charge payable upon exchanges pursuant to
Section 10.05 or the Registration Rights Agreement).

         Without the prior consent of the Company, the Registrar is not required
(a) to register the transfer or exchange of any Note selected for redemption,
(b) to register the transfer or exchange of any Note for a period of 15 days
before a selection of Notes to be redeemed or (c) to register the transfer or
exchange of a Note between a record date and the next succeeding interest
payment date.

Section 2.06  Replacement Notes

         If any mutilated Note is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon receipt of a
Company Order, shall authenticate a replacement Note if the Trustee's
requirements are met. The Trustee or the Company may require that the Holder
supply an indemnity bond that is sufficient in the judgment of the Trustee and
the Company to protect the Company, the Trustee, any Agent or any authenticating
agent from any loss which any of them may suffer if a Note is replaced. The
Company may charge for its expenses in replacing a Note.

         Every replacement Note is an additional obligation of the Company.

Section 2.07  Outstanding Notes

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section 2.07 as not outstanding.

         If a Note is replaced pursuant to Section 2.06, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

         If the principal amount of any Note is considered paid under Section
5.01, it ceases to be outstanding and interest on it ceases to accrue.

         Except as set forth in Section 2.08, a Note does not cease to be
outstanding because the Company or an Affiliate holds the Note.

Section 2.08  Treasury Notes

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company or by any Affiliate of the Company shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes which the Trustee actually knows are so owned shall be so disregarded.

Section 2.09  Temporary Notes

         Until definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company considers appropriate for temporary Notes. Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate definitive Notes in
exchange for temporary Notes.

Section 2.10  Cancellation

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation. Unless the Company shall direct
by a written order signed by two Officers that canceled Notes be returned to it,
certification of their destruction shall be delivered to the Company. The
Company may not issue new Notes to replace
<PAGE>
 
Notes that it has paid or that have been delivered to the Trustee for
cancellation, provided, however, that the Trustee shall not be required to
destroy Notes.

Section 2.11  Defaulted Interest

         If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful, any
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 5.01. The Company, with the consent of the Trustee, shall fix
each such special record date and payment date. At least 15 days before the
record date, the Company (or the Trustee, in the name of and at the expense of
the Company) shall mail to Holders a notice that states the special record date,
the related payment date and the amount of such interest to be paid.

Section 2.12  CUSIP Numbers

         The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on
the Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers.

Section 2.13  Book-Entry Provisions for Global Notes

         (a) The Global Notes initially shall (i) be registered in the name of
the Depository or the nominee of such Depository, (ii) be delivered to the
Trustee as custodian for such Depository and (iii) bear legends as set forth in
Exhibit C.

         Members of, or participants in, the Depository ("Participants") shall
have no rights under this Indenture with respect to any Global Note held on
their behalf by the Depository, or the Trustee as its custodian, or under the
Global Note, and the Depository may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner of the Global Note
for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
prevent the Company, the Trustee or any agent of the Company or the Trustee from
giving effect to any written certification, proxy or other authorization
furnished by the Depository or impair, as between the Depository and
Participants, the operation of customary practices governing the exercise of the
rights in a Holder of any Note.

         (b) Transfers of Global Notes shall be limited to transfers in whole,
but not in part, to the Depository, its successors or their respective nominees.
Interests of beneficial owners in the Global Notes may be transferred or
exchanged for Physical Notes in accordance with the rules and procedures of the
Depository and the provisions of Section 2.05. In addition, Physical Notes shall
be transferred to all beneficial owners in exchange for their beneficial
interests in Global Notes if (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository for any Global Note and a
successor Depository is not appointed by the Company within 90 days of such
notice or (ii) an Event of Default has occurred and is continuing and the
Registrar has received a request from the Depository to issue Physical Notes.

         (c) In connection with the transfer of Global Notes as an entirety to
beneficial owners pursuant to paragraph (b) of this Section 2.13, the Global
Notes shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall upon receipt of Company Order
authenticate and deliver, to each beneficial owner identified by the Depository
in exchange for its beneficial interest in the Global Notes, an equal aggregate
principal amount of Physical Notes of authorized denominations.

         (d) Any Physical Notes constituting a Restricted Note delivered in
exchange for an interest in a Global Note pursuant to paragraph (b) of this
Section 2.13 shall, except as otherwise provided by Section 2.05, bear the
Private Placement Legend.
<PAGE>
 
          (e)  The Holder of any Global Note may grant proxies and otherwise
authorize any Person, including Participants and Persons that may hold interests
through Participants, to take any action which a Holder is entitled to take
under this Indenture or the Notes.

Section 3.04, it shall furnish to the Trustee, within five days after an Asset
Sale Offer Date, an Officers' Certificate setting forth the Asset Sale Payment
Date, the principal amount of Notes the Company is offering to purchase and the
purchase price of such Notes, and further setting forth a statement to the
effect that (a) the Company has consummated an Asset Sale and (b) the conditions
set forth in Section 5.09(a) have been satisfied.

Section 3.02   Notices to Holders

          (a)  As provided in Section 3.04, within 15 days after an Asset Sale
Offer Date, the Company shall mail a notice by first-class mail to each Holder.

          (b)  The notice shall state:

          (1)  that an Asset Sale Offer is being made pursuant to Section 3.04
and the length of time the Asset Sale Offer will remain open;
          (2)  the purchase price and the Asset Sale Payment Date;
          (3)  the principal amount of Notes the Company is offering to
purchase;
          (4)  that any Note not tendered or accepted for payment will continue
to accrue interest;
          (5)  that any Note accepted for payment pursuant to the Asset Sale
Offer shall cease to accrue interest on the Asset Sale Payment Date;
          (6)  that Holders electing to have a Note purchased pursuant to any
Asset Sale Offer will be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse side of the Note completed,
to the Company, a depository if appointed by the Company or a Paying Agent at
the address specified in the notice prior to termination of the Asset Sale
Offer;
          (7)  that Holders will be entitled to withdraw their election if the
Company, depository or Paying Agent, as the case may be, receives, not later
than the expiration of the Asset Sale Offer Period, or such longer period as may
be required by law, a telegram, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of the Note the Holder delivered
for purchase and a statement that such Holder is withdrawing his election to
have the Note purchased;
          (8)  that, if the aggregate principal amount of Notes surrendered by
Holders exceeds the aggregate principal amount of Notes offered to be purchased,
the Company shall select the Notes to be purchased on a pro rata basis or by lot
(with such adjustments as may be deemed appropriate by the Company so that only
Notes in denominations of $1,000 or integral multiples thereof shall be
purchased);
          (9)  that Holders whose Notes are purchased only in part will be
issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered; and
          (10) the instructions that Holders must follow to tender their Notes.

          (c)  At the Company's written request, the Trustee shall give any
notice required in this Section 3.02 in the Company's name and at its expense;
provided, however, that the Company shall deliver to the Trustee on or prior to
the fifth day following an Asset Sale Offer Date an Officers' Certificate
requesting that the Trustee give such notice and setting forth the information
to be stated in such notice as provided in this Section 3.02.
<PAGE>
 
Section 3.03  Deposit of Purchase Price

          One Business Day prior to the Asset Sale Payment Date, the Company
shall deposit with the Trustee or with the Paying Agent money sufficient to pay
the purchase price of, and accrued interest on, all Notes to be purchased on
that date. Upon completion of any Asset Sale Offer, the Trustee shall return to
the Company any money not required for that purpose.

          If the Company complies with the preceding paragraph, interest on the
Notes or portions thereof purchased pursuant to any Asset Sale Offer will cease
to accrue on the Asset Sale Payment Date. If any Note to be purchased shall not
be so paid on the Asset Sale Payment Date, because of the failure of the Company
to comply with the preceding paragraph, then interest will be paid on the unpaid
principal from the Asset Sale Payment Date until such principal is paid and on
any interest not paid on such unpaid principal, in each case, at the rate
provided in the Notes and in Section 5.01.

Section 3.04  Asset Sale Offer

          (a) Within 15 days after an Asset Sale Offer Date, the Company shall
mail (with notice to the Trustee) or shall cause the Trustee to mail (in the
Company's name and at its expense) notice of any Asset Sale Offer to each Holder
of Notes as set forth in Section 3.02. The Asset Sale Offer shall be deemed to
have commenced on the date of such mailing and shall terminate 20 Business Days
after its commencement unless a longer offering period is required by law (the
"Asset Sale Offer Period"). Promptly after the termination of the Asset Sale
Offer Period (the "Asset Sale Payment Date"), the Company shall purchase and
mail or deliver payment for, on a pro rata basis or as selected by lot, from
Holders tendering their Notes pursuant to an Asset Sale Offer, the amount of
Notes required to be purchased pursuant to Section 5.09. If an Asset Sale
Payment Date is on or after an interest payment record date and on or before the
related Interest Payment Date, accrued interest will be paid to the Person in
whose name a Note is registered at the close of business on such record date,
and no additional interest will be payable to Holders who tender Notes pursuant
to any such Asset Sale Offer.

          (b) On or before any Asset Sale Payment Date, the Company, to the
extent lawful, shall (i) accept for payment (on a pro rata basis or as selected
by lot) Notes or portions thereof tendered pursuant to the Asset Sale Offer,
(ii) if the Company appoints a depositary or Paying Agent, deposit with such
depositary or Paying Agent money sufficient to pay the purchase price of all
Notes or portions thereof so accepted, (iii) deliver or cause the depositary or
Paying Agent to deliver to the Trustee Notes so accepted and (iv) deliver an
Officers' Certificate identifying the Notes or portions thereof accepted for
payment by the Company in accordance with the terms of this Section 3.04. The
depositary, the Paying Agent or the Company, as the case may be, promptly shall
mail or deliver to each tendering Holder an amount equal to the purchase price
of the Notes tendered by such Holder and accepted by the Company for purchase
and the Trustee promptly shall authenticate and mail or deliver to any such
Holder a new Note equal in principal amount to any unpurchased portion of the
Note surrendered by such Holder. Any Notes not so accepted promptly shall be
mailed or delivered by the Company to the Holder thereof. The Company will
publicly announce the results of any Asset Sale Offer on the Asset Sale Payment
Date.

          (d) Any offer to purchase Notes pursuant to this Section 3.04 shall be
made pursuant to the provisions of Sections 3.01, 3.02 and 3.03.

          (e) Any such offer shall be conducted in compliance with applicable
tender offer rules, including Section 14(e) of the Exchange Act and Rule 14e-1
thereunder, and any other applicable securities laws or regulations.

Section 4.02  Notices to Trustee and Paying Agent

          If the Company elects to redeem Notes pursuant to Section 4.01 and
Section 5 of the Notes, it shall notify the Trustee and the Paying Agent in
writing of the redemption date and the principal amount of Notes to be redeemed.
The Company shall give each notice provided for in this Section 4.02 at least 60
days before the redemption date, together with an Officers' Certificate stating
that such redemption shall comply with the conditions contained herein and in
the Notes.

Section 4.03  Selection of Notes to be Redeemed

          If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes being redeemed are listed or, if the Notes are not listed on a national
securities exchange, on a pro rata basis, by lot or by such other method as the
Trustee shall deem fair and appropriate.

          The Trustee shall make the selection from the Notes outstanding and
not previously called for redemption.  The Trustee promptly shall notify the
Company in writing of such Notes selected for redemption and, in the case of
Notes selected for partial redemption, the principal amount to be redeemed.  The
Trustee may select for redemption portions (equal to $1,000 or any integral
multiple thereof) of the principal of Notes that have denominations larger than
$1,000.  The Notes and portions thereof the Trustee selects shall be in amounts
of $1,000 or integral multiples of $1,000.  Provisions of this Indenture that
apply to Notes called for redemption also apply to portions of Notes called for
redemption.

Section 4.04  Notice to Holders

          At least 30 days but not more than 60 days prior to a redemption date,
the Company shall mail or cause the mailing of a notice of redemption by first-
class mail to each Holder of Notes to be redeemed and the Trustee and Paying
Agent.

redeemed and shall state:

     (1)  the redemption date;
     (2)  the redemption price and the amount of accrued interest, if any, to be
paid;
     (3)  the name and address of the Paying Agent;
     (4)  that Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price and accrued interest, if any;
     (5)  that, unless the Company defaults in making the redemption payment,
interest on Notes called for redemption ceases to accrue on and after the
redemption date and the only remaining right of the Holders is to receive
payment of the redemption price, together with accrued and unpaid interest
thereon to the redemption date, upon surrender to the Trustee or the Paying
Agent of the Notes so redeemed;
<PAGE>
 
     (6)  if any Note is being redeemed in part, the portion of the principal
amount (equal to $1,000 or any integral multiple thereof) of such Note to be
redeemed, and that, on and after the redemption date, upon surrender of such
Note, a new Note or Notes in principal amount equal to the unredeemed portion
thereof shall be issued without charge to the Holder; and
     (7)  if less than all of the Notes are to be redeemed, the identification
of the particular Notes (or portion thereof) to be redeemed, as well as the
aggregate principal amount of Notes to be redeemed and the aggregate principal
amount of Notes estimated to be outstanding after the redemption.

At the Company's request, the Trustee shall give the notice of redemption in the
Company's name and at the Company's expense.

Section 4.05  Effect of Notice of Redemption

         Once notice of redemption is mailed, Notes called for redemption become
due and payable on the redemption date and at the redemption price and shall
cease to bear interest from and after the redemption date (unless the Company
shall default in the payment of the redemption price or accrued interest). Upon
surrender to the Paying Agent, such Notes shall be paid at the redemption price,
plus accrued interest to the redemption date but any interest installment with
respect to an Interest Payment Date that is on or prior to such redemption date
shall be payable on such Interest Payment Date to Holders of record at the close
of business on the record date referred to in the Notes.

Section 4.06  Deposit of Redemption Price

         At least one Business Day prior to the redemption date, the Company
shall deposit with the Paying Agent money sufficient to pay the redemption price
of and accrued interest on all Notes or portions thereof to be redeemed on that
date.

         If any Note surrendered for redemption in the manner provided in this
Indenture shall not be so paid on the redemption date due to the failure of the
Company to deposit sufficient funds with the Paying Agent, interest shall
continue to accrue from the redemption date until such payment is made on the
unpaid principal and, to the extent lawful, on any interest not paid on such
unpaid principal, in each case at the date and in the manner provided in the
Notes.

Section 4.07  Notes Redeemed in Part

         Upon surrender of a Note that is redeemed in part, the Company shall
issue and the Trustee shall authenticate for the Holder a new Note equal in
principal amount to the unredeemed portion of the Note surrendered.

Section 5.01  Payment of Notes

         The Company shall pay the principal of, premium, if any, and interest
on the Notes on the dates and in the manner provided in the Notes. Principal of,
premium, if any, and interest shall be considered paid on the date due if the
Paying Agent, other than the Company or a Subsidiary of the Company, holds on
that date money deposited by the Company designated for and sufficient to pay
all principal of, premium, if any, and interest then due.

         The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the
extent lawful; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent
lawful.

Section 5.02  Maintenance of Office or Agency

          The Company will maintain, in the Borough of Manhattan, The City of
New York, an office or agency (which may be an office of the Trustee or the
Registrar) where Notes may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee.

          The Company also from time to time may designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and from time to time may rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York for such purposes.  The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

          The Company hereby designates the Corporate Trust Office of the
Trustee as one such office or agency of the Company in accordance with Section
2.03.

Section 5.03  Change of Control

          (a) Upon the occurrence of a Change of Control, the Company will offer
(a "Change of Control Offer") to purchase all outstanding Notes at a purchase
price equal to 101% of the aggregate principal amount of the Notes, plus accrued
and unpaid interest, if any, to the date of purchase.  The Change of Control
Offer shall be deemed to have commenced upon mailing of the notice described in
Section 5.03(b), which notice shall specify a payment date (which shall be no
earlier than 30 days nor later than 60 days from the date such notice is
mailed), and shall terminate on the specified payment date, unless a longer
offering period is required by law.  Promptly after the termination of the
Change of Control Offer (the "Change of Control Payment Date"), the Company will
purchase and mail or deliver payment for all Notes tendered in response to the
Change of Control Offer.  If the Change of Control Payment Date is on or after
an interest payment record date and on or before the related Interest Payment
Date, any accrued interest will be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional
interest will be payable to Holders who tender Notes pursuant to the Change of
Control Offer.

          (b) Within 30 days after any Change of Control, the Company, or the
Trustee at the Company's request and expense, will mail or cause to be mailed to
all Holders on the date of the Change of Control a notice of the occurrence of
such Change of Control. Such notice, which shall govern the terms of the Change
of Control Offer, shall state:

          (1) that a Change of Control has occurred and that the Holders have
the right to require the Company to purchase any or all of the outstanding Notes
at a purchase price equal to 101% of the principal amount thereof plus accrued
and unpaid interest, if any, to the date of purchase;

          (2) that the Change of Control Offer is being made pursuant to this
Section 5.03 and the length of time the Change of Control Offer will remain
open;

          (3) the purchase price and the Change of Control Payment Date;

          (4) that any Note not tendered will continue to accrue interest;

          (5) that any Note accepted for payment pursuant to the Change of
Control Offer shall cease to accrue interest on the Change of Control Payment
Date;
<PAGE>
 
          (6)  that Holders electing to have a Note purchased pursuant to any
Change of Control Offer will be required to surrender the Note, with the form
entitled "Option of Holder to Elect Purchase" on the reverse side of the Note
completed, to the Company, a depository if appointed by the Company or a Paying
Agent at the address specified in the notice prior to termination of the Change
of Control Offer;

          (7)  that Holders will be entitled to withdraw their election if the
Company, depository or Paying Agent, as the case may be, receives, not later
than the expiration of the Change of Control Offer, or such longer period as may
be required by law, a telegram, facsimile transmission or letter setting forth
the name of the Holder, the principal amount of the Note the Holder delivered
for purchase and a statement that such Holder is withdrawing his election to
have the Note purchased;

          (8)  that Holders whose Notes are purchased only in part will be
issued Notes equal in principal amount to the unpurchased portion of the Notes
surrendered;

          (9)  the instructions, determined by the Company consistent with this
Indenture, that Holders must follow in order to have their Notes purchased;

          (10) the circumstances and relevant facts regarding such Change of
Control (including without limitation information with respect to pro forma
historical income, cash flow and capitalization after giving effect to such
Change of Control); and

          (11) information regarding the Persons acquiring control and an
information regarding such Person's business plans going forward.

          (c)  On, but in no event before, a Change of Control Payment Date, the
Company, to the extent lawful, will:  (i) deposit with the depository or Paying
Agent, if the Company appoints any depository or Paying Agent, money in
immediately available funds sufficient to pay the purchase price of all Notes
tendered; (ii) deliver or cause such depository or Paying Agent to deliver to
the Trustee Notes so tendered; and (iii) deliver an Officers' Certificate
identifying the Notes accepted for payment by the Company in accordance with the
terms of this Section 5.03.  The depository, the Paying Agent or the Company, as
the case may be, promptly shall mail or deliver to each tendering Holder an
amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase, and the Trustee promptly shall
authenticate and mail or deliver to such Holders a new Note equal in principal
amount to any unpurchased portion of the Note so surrendered. Any Notes not
accepted promptly shall be mailed or delivered by the Company to the Holder
thereof.  The Company publicly will announce the results of the Change of
Control Offer on the Change of Control Payment Date.

          (d)  Neither the Board of Directors nor the stockholders of the
Company may adopt a Plan of Liquidation that provides for or contemplates, or
the effectuation of which is preceded by, (i) the sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company
otherwise than substantially as an entirety, and (ii) the distribution of all or
substantially all of the proceeds of such sale, lease, conveyance or other
disposition and of the remaining assets of the Company to the holders of the
Company's Capital Stock unless, prior to making any liquidating distribution
pursuant to such Plan of Liquidation, the Company makes provision for the
satisfaction of its obligations hereunder and under the Notes. The Company shall
be deemed to have made provision for such payments only if the Company delivers
in trust to the Trustee or Paying Agent (other than the Company or a Subsidiary)
money or U.S. Government Obligations maturing as to principal and interest in
such amounts and at such times as are sufficient without consideration of any
reinvestment of such principal or interest to pay, when due, the principal of
and interest on the Notes and also delivers to the Trustee an Opinion of Counsel
or a tax ruling to the effect that Holders of the Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such action
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 if such action has not
been taken; provided, however, that the Company shall not make any liquidating
distribution until after the Company shall have certified to the Trustee with an
Officers' Certificate at least five days prior to the making of any liquidating
distribution that it has complied with the provisions of this Section 5.03(d)
and that no Default or Event of Default then exists or would occur as a result
of any such liquidating distribution.
<PAGE>
 
          (e) Any Change of Control Offer will be conducted in compliance with
applicable tender offer rules, including Section 14(e) of the Exchange Act and
Rule 14e-1 promulgated thereunder, and any other applicable securities laws or
regulations.

Section 5.04  Limitations on Additional Indebtedness

          (a) After the date hereof: (i) the Company 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 (collectively, "incur"), any Indebtedness (including without
limitation Acquired Indebtedness), other than (A) Junior Subordinated
Indebtedness incurred by the Company in compliance with the provisions of the
immediately following sentence or (B) Indebtedness between the Company and its
Wholly Owned Restricted Subsidiaries (provided that such Indebtedness of the
Company to any Wholly Owned Restricted Subsidiary is expressly subordinated in
right of payment to the Notes) or among such Wholly Owned Restricted
Subsidiaries (provided, however, that any subsequent issue or transfer of any
Capital Stock that results in any such Wholly Owned Restricted Subsidiary
ceasing to be a Wholly Owned Restricted Subsidiary or any transfer of such
Indebtedness (other than to a Wholly Owned Restricted Subsidiary) shall be
deemed, in each case, to constitute the incurrence of such Indebtedness by the
Company) and (ii) the Company will not permit any of its Restricted Subsidiaries
to issue (except to the Company or any of its Wholly Owned Restricted
Subsidiaries) any Capital Stock having a preference in liquidation or with
respect to the payment of dividends, unless, after giving effect thereto, the
Company's Consolidated Fixed Charge Coverage Ratio on the date thereof would be
at least:

          (1) 2.25 to 1, if such date is on or prior to February 28, 1998; and

          (2) 2.50 to 1, if such date is after February 28, 1998,

in each case determined on a pro forma basis as if the incurrence of such
additional Indebtedness or the issuance of such Capital Stock, as the case may
be, and the application of the net proceeds therefrom, had occurred at the
beginning of the four-quarter period used to calculate the Company's
Consolidated Fixed Charge Coverage Ratio.  In addition, after the date hereof
the Company will not directly or indirectly incur any Junior Subordinated
Indebtedness unless, after giving effect thereto, the Company's Consolidated
Fixed Charge Coverage Ratio on the date thereof would be at least 1.50 to 1, in
each case determined on a pro forma basis as if the incurrence of such
additional Indebtedness, and the application of the net proceeds therefrom, had
occurred at the beginning of the four-quarter period used to calculate the
Company's Consolidated Fixed Charge Coverage Ratio.

          (b) Notwithstanding the provisions of Section 5.04(a), the Company and
its Restricted Subsidiaries may: (i) incur Indebtedness under the Bank Credit
Agreement in an amount not to exceed $60,000,000; (ii) incur Indebtedness not
otherwise permitted by any other provision hereof, so long as the aggregate
principal amount of Indebtedness incurred under this clause (ii) does not exceed
7.5% of the Consolidated Tangible Assets of the Company; and (iii) incur
Refinancing Indebtedness. In addition, notwithstanding the provisions of Section
5.04(a): (A) Subsidiaries of the Company that are not Wholly Owned Restricted
Subsidiaries may incur Indebtedness to the Company or any of its Wholly Owned
Restricted Subsidiaries in the amounts and subject to the restrictions in
Section 5.05(iii) and (B) Single Purpose Subsidiaries of the Company may incur
Non-Recourse Indebtedness to the extent permitted by Section 5.05(iv).

          (c) Notwithstanding the provisions of Sections 5.04(a) and 5.04(b),
the Company may not incur any Indebtedness if such Indebtedness is subordinate
or junior in ranking in any respect to any Senior Indebtedness unless such
Indebtedness is Junior Subordinated Indebtedness. In addition, the Company may
not incur any secured Indebtedness which is not Senior Indebtedness unless
contemporaneously therewith effective provision is made to secure the Notes
equally and ratably with such secured Indebtedness for so long as such secured
Indebtedness is secured by a Lien.

Section 5.05  Limitations on Subsidiary Debt and  Preferred Stock
<PAGE>
 
          After the date hereof, the Company 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
(collectively, "incur"), any Indebtedness (which, with respect to any Restricted
Subsidiary, includes without limitation preferred stock of such Restricted
Subsidiary) except: (i) guarantees by any Restricted Subsidiary of the payment
of the principal of, premium, if any, and interest on the Indebtedness incurred
pursuant to the Bank Credit Agreement and in compliance with the provisions of
Section 5.04(b)(i) and with the provisions of Section 5.11; (ii) Indebtedness
issued to and held by the Company or a Wholly Owned Restricted Subsidiary of the
Company (provided, however, that any subsequent issue or transfer of any Capital
Stock that results in any such Wholly Owned Restricted Subsidiary ceasing to be
a Wholly Owned Restricted Subsidiary or any transfer of such Indebtedness (other
than to a Wholly Owned Restricted Subsidiary) shall be deemed, in each case, to
constitute the incurrence of such Indebtedness by such Restricted Subsidiary);
(iii) Indebtedness to the Company or any of its Wholly Owned Restricted
Subsidiaries incurred by Subsidiaries of the Company that are not 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 in compliance with the provisions of
Section 5.06(b)(E)) not to exceed 5% of Consolidated Tangible Assets; and (iv)
Non-Recourse Indebtedness incurred by a Single Purpose Subsidiary.

Section 5.06  Limitations on Restricted Payments

          (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, make any Restricted Payment if at the
time of such Restricted Payment:

          (i)   a Default or Event of Default shall have occurred and be
continuing or shall occur as a consequence thereof;

          (ii)  the Company would be unable to incur an additional $1.00 of
Senior Indebtedness under the provisions of Section 5.04(a); or

          (iii) the amount of such Restricted Payment, when added to the
aggregate amount of all Restricted Payments (other than those made pursuant to
the provisions of clause (A), (C), (D), (E) or (G) of Section 5.06(b)) made
after the date of this Indenture, exceeds the sum of: (a) 50% of the Company's
Consolidated Net Income accrued during the period from the date of this
Indenture to the end of the Company's most recently ended fiscal quarter for
which financial results have been reported at the time of such Restricted
Payment (or, if such aggregate Consolidated Net Income shall be a deficit, minus
100% of such aggregate deficit); plus (b) the aggregate amount of Net Reductions
in Investments attributable to Designated Investments made by the Company or any
Subsidiary subsequent to the date of this Indenture; provided, however, that (1)
the Net Reductions in Investments attributable to any Designated Investment for
purposes of this calculation shall not exceed the amount of such Designated
Investment, (2) to the extent that cash or Cash Equivalents included in any Net
Reductions in Investments pursuant to the definition thereof have been or will
be included in the computation of Consolidated Net Income for purposes of
determining the ability of the Company or any of its Restricted Subsidiaries to
make Restricted Payments under clause (iii)(a) of this Section 5.06(a), such
cash or Cash Equivalents shall not also be included in computing Net Reductions
in Investments for purposes of this clause (iii)(b) and (3) the Company will not
be permitted to make any Restricted Payment described in clause (i) or (ii) of
the definition of Restricted Payment from any Net Reductions in Investments.

          (b) Notwithstanding the foregoing, the provisions of clauses (ii) and
(iii) of Section 5.06(a) will not prevent:

          (A) the Company or any Wholly Owned Restricted Subsidiary from making
Investments in Subsidiaries, in an aggregate amount not to exceed $4,000,000,
pursuant to contractual obligations in existence on the date of this Indenture
or directly related to projects in existence on the date of this Indenture;

          (B) the Company from paying any dividend within 60 days after the date

the net proceeds of a substantially concurrent sale (other than to a Subsidiary
of the Company or an employee stock ownership plan) of, shares of Qualified
Capital Stock of the Company;

          (D) the Company or any Subsidiary from making (1) Investments pursuant
to the provisions of employee benefit plans of the Company or any of its

of residence, approved by a majority of the independent members of the Board of
Directors of the Company, provided that the aggregate amount of Investments and
loans under this clause (D) shall not exceed $1,000,000 in any fiscal year;

          (E) the Company or any Wholly Owned Restricted Subsidiary from making
Designated Investments (1) in Subsidiaries that are not Wholly Owned Restricted

on behalf of Subsidiaries that  are not Wholly Owned Restricted Subsidiaries in
compliance with the provisions of Section 5.05(iii)) not to exceed 5% of
Consolidated Tangible Assets or (2) in Joint Ventures in an aggregate amount not
to exceed 5% of Consolidated Tangible Assets, provided that:  (x) the Person in
whom the Investment is made is engaged only in Permitted Businesses; (y) the
Company, directly or through Wholly Owned Restricted Subsidiaries of the
Company, controls, under an operating and management agreement or otherwise, the
day to day management and operation of such Person or otherwise has the right to
exercise significant influence over the management and operation of such Person
in all material respects (including without limitation the right to control or
veto any material act or decision); and (z) after giving effect to such
Investment, the aggregate amount of Indebtedness and Investments made by the
Company and its Subsidiaries in such Person does not exceed $5,000,000;

          (F) the Company or any Wholly Owned Restricted Subsidiary from making
Designated Investments in Subsidiaries that are not Wholly Owned Restricted
Subsidiaries or in Joint Ventures; provided that such Designated Investments are
made solely from (1) the net proceeds of a substantially concurrent sale (other
than to a Subsidiary of the Company or an employee stock ownership plan) of
shares of Qualified Capital Stock of the Company, (2) 50% of the Company's
Consolidated Net Income accrued during the period from the date of this
Indenture to the end of the Company's most recently ended fiscal quarter for
which financial results have been reported at the time of such Restricted
Payment or (3) the aggregate amount of Net Reductions in Investments (not to
exceed the aggregate amount of such Designated Investments) made by the Company
or any Subsidiary subsequent to the date of this Indenture;

          (G) the Company from redeeming for cash all (but not less than all) of
the outstanding shares of the Company's Series 2D Senior Preferred Stock;
provided, however, that such redemption shall not be at a price in excess of the
redemption price set forth in Section 17.01 of the Company's Amended and
Restated Certificate of Incorporation in effect as of the date of this
Indenture; and provided, further, that prior to January 13, 1997, the Company
shall not redeem any of the outstanding shares of the Company's Series 2D Senior
Preferred Stock until the Company delivers to the Trustee an Officer's
Certificate certifying that the Company's earnings before interest and taxes for
the most recent twelve (12) month period calculated in accordance with generally
accepted accounting principles equalled or exceeded $27 million. Nothing
contained in this further proviso shall affect the Company's right to redeem the
Series 2D Senior Preferred Stock no later than January 13, 1997; or

          (H) the Company from (1) making all regular quarterly dividends, each
such quarterly dividend payment not to exceed $487,500 in the aggregate of
$2,437.50 per share, on the outstanding shares of the Company's Series 2D Senior
Preferred Stock; and (2) making all payments of any dividends of up to 9.75% on
the aggregate unpaid amount of any regular quarterly dividend on the outstanding
shares of the Company's Series 2D Senior Preferred Stock from the date such
regular quarterly dividend should have been paid to the date of the payment of
such dividend; in consideration thereof, and except as provided below, the
               ------------------------------------------------------
Company shall increase the Interest payable on the Notes by one percent (1%)
(the "Additional Interest") from the date of this Indenture, such Additional
Interest payable as provided for in the Notes. The Company files its financial
results with the Securities and Exchange Commission on quarterly and annual
reports, and these reports include the Company's earnings after deducting
minority interests and before interest, taxes, depreciation, and amortization
calculated in accordance with generally accepted accounting principles
("Earnings"). The Company will measure its Earnings for trailing twelve month
periods, each period to end on the last day of a fiscal quarter and extend no
further than March 31, 1998 (each a "Quarterly Measurement Period").  
<PAGE>
 
If the Company's Earnings equal or exceed $36 million for two consecutive
Quarterly Measurement Periods, then the Company is relieved of its obligation to
pay any future Additional Interest. However, if the Company's Earnings do not
equal or exceed $36 million for any subsequent Quarterly Measurement Period, up
to and including the Quarterly Measurement Period ending March 31, 1998, the
Company is obligated to commence paying Additional Interest until the Company's
Earnings again equal or exceed $36 million on a trailing twelve month basis
calculated quarterly.

Section 5.07  Limitations on Restrictions on Distributions from Subsidiaries

Restricted Subsidiaries, except for (i) Payment Restrictions covering not more
than $1,000,000 in the aggregate of retained earnings of ICF Kaiser Servicios

Existing Indebtedness or existing contracts to which the Company or any of its

Payment Restriction only applies to assets that were subject to such
restrictions and encumbrances prior to the acquisition of such assets by the
Company or its Restricted Subsidiaries and (iv) any such Payment Restriction
arising in connection with Refinancing Indebtedness; provided that any such
Payment Restrictions that arise under such Refinancing Indebtedness are not,
taken as a whole, more restrictive than those under the agreement creating or
evidencing the Indebtedness being refunded or refinanced.

Section 5.08  Limitations on Transactions With Affiliates

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 the Company or any of its Subsidiaries (each an "Affiliate Transaction"),
other than Affiliate Transactions in the ordinary course of business and
consistent with past practice that are fair to the Company or such Restricted
Subsidiary, as the case may be, and are on terms at least as favorable as would
have been obtainable at such time from an unaffiliated party, unless the Board
of Directors of the Company or such Restricted Subsidiary, as the case may be,
pursuant to a Board Resolution reasonably and in good faith determines that such
Affiliate Transaction is fair to the Company or such Restricted Subsidiary, as
the case may be, and is on terms at least as favorable as would have been
obtainable at such time from an unaffiliated party.

          (b) In addition, the Company will not, and will not permit any of its
Restricted Subsidiaries to, enter into any Affiliate Transaction or series of
Affiliate Transactions involving or having a value of more than (i) $1,000,000
unless a majority of the members of the Board of Directors of the Company who
are not affiliated with any other party to such Affiliate Transaction reasonably
and in good faith shall have determined that such Affiliate Transaction or
series of Affiliate Transactions is fair to the Company or such Restricted
Subsidiary, as the case may be, and is on terms at least as favorable as would
have been obtainable at such time from an unaffiliated party and (ii) $5,000,000
unless the Company or such Restricted Subsidiary, as the case may be, has
received an opinion from an Independent Financial Advisor to the effect that the
financial terms of such Affiliate Transaction are fair to the Company or such
Restricted Subsidiary, as the case may be, from a financial point of view.

          (c) The provisions of Sections 5.08(a) and 5.08(b) shall not apply to:

Restricted Subsidiaries receive consideration at the time of such Asset Sale at
least equal to the fair market value of the assets or Capital Stock included in
such Asset Sale; (ii) the aggregate fair market value of the consideration from
such Asset Sale (other than consideration in the form of assumption of
Indebtedness of the Company or one or more of its Restricted Subsidiaries from
which the Company or such Restricted Subsidiaries, as the case may be, are
released) that is not in the form of cash or Cash Equivalents shall not, when
aggregated with the fair market value of all other non-cash or non-Cash
Equivalent consideration received by the Company and its Restricted Subsidiaries
from all previous Asset Sales since the date of this Indenture that have not yet
been converted into cash or Cash Equivalents, exceed 5% of Consolidated Tangible
Assets of the Company at the time of such Asset Sale; and (iii) if the aggregate

Business Investment; (ii) apply or cause to be applied the cash and Cash
Equivalent portion of the Net Proceeds of such Asset Sale to repay outstanding
Senior Indebtedness of the Company or any Restricted Subsidiary, provided,
however, that any such repayment of Indebtedness under any revolving credit
facility or similar agreement shall result in a permanent reduction in the
lending commitment relating thereto in an amount equal to the principal amount
so repaid; or (iii) apply or cause to be applied the cash and Cash Equivalent
portion of the Net Proceeds of such Asset Sale that is neither reinvested as
provided in clause (i) nor applied to the repayment of Senior Indebtedness as
provided in clause (ii), first to the purchase of Existing Notes tendered to the
                         -----

          (c) Notwithstanding the provisions of Sections 5.09(a) and 5.09(b):
(i) 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 such Net Proceeds so affected will not be required
to be applied in the manner set forth in this Section 5.09 but may be retained
by the applicable Foreign Subsidiary so long, but only so long, as the
applicable local law will not permit repatriation to the United States (the
Company hereby agreeing to cause the applicable Foreign Subsidiary promptly to
take all actions required by the applicable local law to permit such
repatriation) and, once such repatriation of any of such affected Net Proceeds
is permitted under the applicable local law, such repatriation will be
immediately effected and such repatriated Net Proceeds will be applied in the
manner set forth in this Section 5.09; and (ii) to the extent that the Board of
Directors has determined 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 so affected may be retained by the applicable
Foreign Subsidiary for so long as such material adverse tax consequence would
continue.

provisions of Section 5.05(i) and (ii) guarantees delivered pursuant to the Bank
Credit Agreement by Subsidiaries of the Company who have delivered similar
guarantees prior to the date of this Indenture) unless the Company causes each
such Subsidiary to execute and deliver to the Trustee, prior to or concurrently
with the issuance of such guarantee, a supplemental indenture, in form
satisfactory to the Trustee, pursuant to which such Subsidiary unconditionally
guarantees the payment of principal of, premium, if any, and interest on the

this Indenture, which is hereby incorporated in and expressly made a part of
this Indenture.

Section 5.12  SEC Reports

          (a) At any time that the Company has a class of securities registered

which the Company's independent public accountants concur and except that
quarterly statements may be subject to year-end adjustments.

          (c) Delivery of the above-referenced reports, information and
documents to the Trustee is for informational purposes only and the Trustee's
receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including
the Company's compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

Section 5.13  Corporate Existence

          Subject to the provisions of Sections 5.09 and 6.01, the Company
shall, and shall cause each Restricted Subsidiary to, do or cause to be done all
things necessary to preserve and keep in full force and effect its rights
(charter and statutory), licenses and franchises, except in such cases where a
failure to do so would not have a material adverse effect on (a) the business,
prospects, assets or financial condition of the Company and its Restricted
Subsidiaries taken as a whole, or (b) the Holders.

take the benefit or advantage of any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the Company's
obligation to pay the Notes; and the Company (to the extent that it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law insofar
as such law applies to the Notes, and covenants that it will not, by resort to

same or a similar business.

         (b)  The Company will and will cause each Subsidiary to keep proper
books of record and account in which full and correct entries shall be made of
all financial transactions and the assets and business of the Company and each
Subsidiary, in accordance with GAAP consistently applied to the Company and its
Subsidiaries taken as a whole.

         (c)  The Company will and will cause each Subsidiary to comply with all
statutes, laws, ordinances or government rules and regulations to which it is
subject, non-compliance with which would materially adversely affect the
business, prospects, earnings, properties, assets or condition (financial or
otherwise) of the Company and its Subsidiaries taken as a whole.

Section 5.16  Inspection and Confidentiality

         (a)  The Company shall, and shall cause each of its Subsidiaries to,
permit authorized representatives of the Trustee to visit and inspect the
properties of the Company or its Subsidiaries, all upon reasonable prior notice
and at such reasonable times during normal business hours and as often as may be
reasonably requested.

         (b)  The Trustee and its authorized representatives referred to in
Section 5.16(a) agree not to use any information obtained pursuant to this
Section 5.16 for any unlawful purpose and to keep confidential and not to
disclose any such information to any Person except that (i) the recipient of the
information may disclose any information that becomes publicly available other
than as a result of disclosure by such recipient, (ii) the recipient of the
information may disclose any information that its counsel reasonably concludes
is necessary to be disclosed by law, pursuant to any court or administrative
order or ruling or in any pending legal or administrative proceeding or
investigation after prior written notice, reasonable under the circumstances, to
the Company and (iii) the recipient of the information may disclose any
information necessary to be disclosed pursuant to any provision of the TIA.

         (a)  The Company shall deliver to the Trustee, within 105 days after
the end of each fiscal year of the Company, an Officers' Certificate stating
that a review of the activities of the Company and its Restricted Subsidiaries
during the preceding fiscal year has been made under the supervision of the
signing Officers with a view to determining whether the Company has kept,
observed, performed and fulfilled its obligations under this Indenture, and
further stating, as to each such Officer signing such Officers' Certificate,
that to the best of such Officer's knowledge the Company has kept, observed,
performed and fulfilled each covenant contained in this Indenture and is not in
default in the performance or observance of any of the terms, provisions and
conditions hereof (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which such Officer may have
knowledge and what action the Company is taking or proposes to take with respect
thereto) and that to the best of such Officer's knowledge no event has occurred
and remains in existence by reason of which payments on account of the
<PAGE>
 
principal of, premium, if any, or interest on the Notes are prohibited or, if
such event has occurred, a description of the event and what action the Company
is taking or proposes to take with respect thereto. Such compliance shall be
determined without regard to periods of grace or requirements of notice.

         (b)  So long as not contrary to the then current recommendations of the
American Institute of Certified Public Accountants, the year-end financial
statements delivered pursuant to Section 5.12 shall be accompanied by a written
statement of the Company's independent public accountants (who shall be a firm
of established national reputation) that in making the examination necessary for
certification of such financial statements nothing has come to their attention
that would lead them to believe that the Company has violated any provisions of
Article 5 or 6 or, if any such violation has occurred, specifying the nature and
period of existence thereof, it being understood that such accountants shall not
be liable directly or indirectly to any Person for any failure to obtain
knowledge of any such violation.

         (c)  The Company, so long as any of the Notes are outstanding, will
deliver to the Trustee, within five Business Days of any Officer becoming aware
of any Default or Event of Default under this Indenture, an Officers'
Certificate specifying such Default or Event of Default and what action the
Company is taking or proposes to take with respect thereto.

                                  SUCCESSORS

Section 6.01  Limitations on Mergers and Consolidations

         (a)  The Company, in a single transaction or a series of related
transactions, will not (i) 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 Notes or this Indenture, to any Person or (ii)
adopt a Plan of Liquidation unless, in either case:

         (A)  the Person formed by or surviving such consolidation or merger (if
other than the Company) or to which such sale, lease, conveyance or other
disposition or assignment shall be made (or, in the case of a Plan of
Liquidation, one Person to which assets are transferred) (collectively, the
"Successor"), is a corporation organized and existing under the laws of the
United States or any State thereof or the District of Columbia, and the
Successor assumes by supplemental indenture in a form satisfactory to the
Trustee all of the obligations of the Company under the Notes and this
Indenture;

         (B)  immediately prior to and immediately after and giving effect to
such transaction and the assumption of the obligations as set forth in clause
(A) above and the incurrence of any Indebtedness to be incurred in connection
therewith, no Default or Event of Default shall have occurred and be continuing;
and

         (C)  immediately after and giving effect to such transaction and the
assumption of the obligations as set forth in clause (A) above and the
incurrence of any Indebtedness to be incurred in connection therewith, and the
use of any net proceeds therefrom on a pro forma basis, (1) the Consolidated
Tangible Net Worth of the Company or the Successor, as the case may be, would be
at least equal to the Consolidated Tangible Net Worth of the Company immediately
prior to such transaction and (2) the Company or the Successor, as the case may
be, could incur at least $1.00 of additional Senior Indebtedness under the
provisions of Section 5.04.

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

         (c)  The provisions of Sections 6.01(a) and 6.01(b) will not prohibit a
transaction the sole purpose of which (as determined in good faith by the Board
of Directors of the Company and evidenced by a Board Resolution) is to change
the state of incorporation of the Company or a Single Purpose Subsidiary, as the
case may be, and such transaction does not have as one of its purposes the
evasion of the limitations described above.

Section 6.02  Successor Corporation Substituted
<PAGE>
 
           (a) Upon any consolidation or merger, or any sale, lease, conveyance
or other disposition of all or substantially all of the assets of the Company or
any assignment of its obligations under this Indenture or the Notes in
accordance with Section 6.01, the Successor formed by such consolidation or into
or with which the Company is merged or to which such sale, lease, conveyance or
other disposition or assignment is made shall succeed to, and be substituted
for, and may exercise every right and power of, the Company under this Indenture
with the same effect as if such Successor had been named as the Company herein.

           (b) Subject to the provisions of Section 5.03(a), in the event of any
such sale, lease, conveyance or other disposition (other than a transfer by way
of lease), the Company or any Successor which theretofore shall have been
substituted for the Company pursuant to the provisions of this Article 6 shall
be discharged from all obligations and covenants under this Indenture and the
Notes and may, but need not be, liquidated and dissolved.

           (1) the Company fails to pay interest on any of the Notes when it
becomes due and payable and such failure continues for 30 days;

           (2) the Company fails to pay the principal or premium, if any, of the
Notes when it becomes due and payable, whether at stated maturity, upon
redemption, upon acceleration or otherwise (including failure to make payment
pursuant to a Change in Control Offer or an Asset Sale Offer);

           (3) the Company fails to comply with any covenant in this Indenture
and such failure continues for 60 days after notice of such failure has been
given to the Company by the Trustee or by the Holders of at least 25% of the
aggregate principal amount of the Notes then outstanding;

           (4) the Company or any of its Subsidiaries fail to make any payment
when due or during any applicable grace period in respect of any Indebtedness of
the Company or any of its Subsidiaries, other than Non-Recourse Indebtedness of
a Single Purpose Subsidiary, that has an aggregate outstanding principal amount
of $2,000,000 or more;

           (5) the Company defaults under any Indebtedness, other than
Non-Recourse Indebtedness of a Single Purpose Subsidiary, whether such
Indebtedness existed on the date of this Indenture or thereafter shall be
created, if (A) such default results in the holder or holders of such
Indebtedness causing such Indebtedness to become due prior to its stated
maturity and (B) the principal amount of such Indebtedness, together with the
principal amount of any other such Indebtedness the maturity of which has been
so accelerated, aggregate $2,000,000 or more at any one time outstanding;

           (6) one or more final judgments or orders that exceed $2,000,000 in
the aggregate for the payment of money have been entered by a court or courts of
competent jurisdiction against the Company or any of its Subsidiaries and such
judgment or judgments have not been satisfied, stayed, annulled or rescinded
within 60 days of being entered;

           (7) the Company or any of its Subsidiaries pursuant to or within the
meaning of any Bankruptcy Law:

(a)        commences a voluntary case,

(b)        consents to the entry of an order for relief against it in an
involuntary case,

(c)        consents to the appointment of a Custodian of it or for all or
substantially all of its property, or

<PAGE>
 
(d)        makes a general assignment for the benefit of its creditors; or

(8)        a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that:

           (a) is for relief against the Company or any of its
Subsidiaries as debtor in an involuntary case,

           (b) appoints a Custodian of the Company or any of its
Subsidiaries or a Custodian for all or substantially all of the property of the
Company or any of its Subsidiaries, or

           (c) orders the liquidation of the Company or any of its Subsidiaries,
and the order or decree remains unstayed and in effect for 60 days.

Section 7.02   Acceleration

           If an Event of Default (other than an Event of Default with respect
to the Company specified in clause (7) or (8) of Section 7.01) occurs and is
continuing, the Trustee by written notice to the Company, or the Holders of at
least 25% in aggregate principal amount of the Notes then outstanding by notice
to the Company and the Trustee, may declare all amounts owing under the Notes to
be due and payable immediately for an amount equal to 100% of the principal
amount of the Notes plus accrued and unpaid interest, if any, to date of
payment. Upon such declaration of acceleration, the aggregate principal of and
interest on the Notes shall immediately become due and payable. If an Event of
Default with respect to the Company specified in clause (7) or (8) of Section
7.01 occurs, such an amount shall ipso facto become and be immediately due and
payable without any declaration, notice or other act on the part of the Trustee
or any Holder. The Holders of a majority in aggregate principal amount of the
Notes then outstanding by written notice to the Trustee may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default (except nonpayment of
principal or interest on the Notes that has become due solely as a result of
such acceleration) have been cured or waived.

Section 7.03   Other Remedies

           If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of, premium, if any, or interest on the Notes or to enforce
the performance of any provision of the Notes or this Indenture.

           The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All remedies are cumulative to the extent permitted by law.

Section 7.04   Waiver of Past Defaults

           Subject to the provisions of Section 7.07 and Section 10.02, the
Holders of a majority in principal amount of the then outstanding Notes by
notice to the Trustee may waive an existing Default or Event of Default and its
consequences, except a continuing Default or Event of Default specified in
clause (1), (2), (7) or (8) of Section 7.01 or in respect of the provisions of
Section 5.03 or any provision hereof that cannot be modified or amended without
the consent of the Holder so affected pursuant to Section 10.02. Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

<PAGE>
 
Section 7.05   Control by Majority

           The Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
it. However, the Trustee may refuse to follow any direction that conflicts with
law or this Indenture, that the Trustee determines may be unduly prejudicial to
the rights of other Holders, or that may involve the Trustee in personal
liability.

Section 7.06   Limitations on Suits

           Except as provided in Section 7.07, a Holder may pursue a remedy with
respect to this Indenture or the Notes only if:

           (1) the Holder gives to the Trustee written notice of a
continuing Event of Default;

           (2) the Holders of at least 25% in principal amount of the then
outstanding Notes make a written request to the Trustee to pursue the remedy;

           (3) such Holder or Holders offer to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense;

           (4) the Trustee does not comply with the request within 60 days
after receipt of the request and the offer of indemnity; and

           (5) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Notes do not give the Trustee a direction
inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or
to obtain a preference or priority over another Holder.

Section 7.07   Rights of Holders to Receive Payment

           Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal of, premium, if any, and
interest on the Note, on or after the respective due dates expressed in the
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates, is absolute and unconditional and shall not be impaired or
affected without the consent of the Holder.

Section 7.08   Collection Suit by Trustee

           If an Event of Default specified in Section 7.01(1) or (2) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for the amount of principal,
premium, if any, and interest remaining unpaid on the Notes, determined in
accordance with Section 7.02, and interest on overdue principal and, to the
extent lawful, premium, if any, and interest, and such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

<PAGE>
 
Section 7.09   Trustee May File Proofs of Claim

           The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company, its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any Custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 8.06. Nothing
herein contained shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

Section 7.10   Priorities

           If the Trustee collects any money pursuant to this Article 7, it
shall pay out the money in the following order:

           First:  to the Trustee for amounts due under Section 8.06;

           Second:  to Holders for amounts due and unpaid on the Notes for
interest, ratably, without preference or priority of any kind, according to the
amounts due and payable on the Notes for interest;

           Third:  to Holders for amounts due and unpaid on the Notes for
principal and premium, if any, ratably, without preference or priority of any
kind, according to the amounts due and payable on the Notes for principal and
premium, if any, respectively; and

           Fourth:  as a court of competent jurisdiction may direct.

           The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 7.10.

Section 7.11   Undertaking for Costs

           In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 7.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 7.07 or a suit by Holders of more than 10% in principal
amount of the then outstanding Notes.

Section 7.12   Restoration of Rights and Remedies

           If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Company, the Trustee and the Holder shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                    ARTICLE 8
                                     TRUSTEE

Section 8.01   Duties of Trustee

<PAGE>
 
           (1) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in such exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

           (2) Except during the continuance of an Event of Default:

           (a) the Trustee need perform only those duties that are specifically
set forth in this Indenture and no others, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

           (b) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; however, the
Trustee shall examine the certificates and opinions to determine whether or not
they conform to the requirements of this Indenture.

           (3) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

           (a) this paragraph does not limit the effect of paragraph (2) of this
Section 8.01;

           (b) the Trustee shall not be liable for any error of judgment made in
good faith by a Trust Officer, unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts; and

           (c) the Trustee shall not be liable with respect to any action it
takes or omits to take in good faith in accordance with a direction received by
it pursuant to Section 7.05.

           (4) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(1), (2) and (3) of this Section 8.01.

           (5) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee may refuse to
perform any duty or exercise any right or power unless it receives indemnity
satisfactory to it against any loss, liability or expense.

           (6) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

Section 8.02   Rights of Trustee

           Subject to the provisions of Section 8.01:

           (1) The Trustee may rely on any document believed by it to be genuine
and to have been signed or presented by the proper Person. The Trustee need not
investigate any fact or matter stated in the document.

           (2) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel and an Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon.

           (3) The Trustee may act through agents and shall not be responsible
for the misconduct or negligence of any agent (other than an agent who is an
employee of the Trustee) appointed with due care.

<PAGE>
 
           (4) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers conferred upon it by this Indenture.

           (5) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

           (6) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders pursuant to this Indenture, unless such Holders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred by it in compliance with such
request or direction.

Section 8.03   Individual Rights of Trustee

           The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any of its
Affiliates with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights.

Section 8.04   Trustee's Disclaimer

           The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Notes. It shall not be accountable for the Company's use
of the proceeds from the Notes or any money paid to the Company or upon the
Company's direction under any provision hereof. It shall not be responsible for
the use or application of any money received by any Paying Agent other than the
Trustee. It shall not be responsible for any statement or recital herein or any
statement in the Notes other than its certificate of authentication.

Section 8.05   Notice of Defaults

           If a Default or Event of Default occurs and is continuing and if it
is known to the Trustee, the Trustee shall mail to Holders, as their names and
addresses shall appear on the Notes register, a notice of the Default or Event
of Default within 60 days after it occurs. Except in the case of a Default or
Event of Default in payment of principal of, premium, if any, or interest on any
Note or that resulted from a failure to comply with Section 5.03, the Trustee
may withhold the notice if and so long as a committee of its Trust Officers in
good faith determines that withholding the notice is in the interests of
Holders.

Section 8.06   Compensation and Indemnity

           The Company shall pay to the Trustee such compensation as the Company
and the Trustee may from time to time agree upon in writing for its acceptance
of this Indenture and services hereunder. The Trustee's compensation shall not
be limited by any law on compensation of a trustee of an express trust. The
Company shall reimburse the Trustee upon request for all reasonable
disbursements, advances and expenses incurred by it. Such expenses shall include
the reasonable compensation, disbursements and expenses of the Trustee's agents
and counsel.

           The Company shall indemnify each of the Trustee and any predecessor
Trustee against any and all loss, damage, claim, liability or expense including
taxes (other than taxes based upon, measured by or determined by the income of
the Trustee), incurred by it arising out of or in connection with the acceptance
or administration of its duties under this Indenture, except as set forth in the
next paragraph. The Trustee promptly shall notify the Company of any claim for
which it may seek indemnity. The Company shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel. The Company
need not pay for any settlement made without its consent, which consent shall
not be unreasonably withheld.

           The Company need not reimburse any expense or indemnify against any
loss or liability incurred by the Trustee through negligence or bad faith.

<PAGE>
 
           To secure the Company's payment obligations in this Section 8.06, the
Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal of,
premium, if any, and interest on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture.

           When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 7.01(7) or (8) occurs, the expenses (including
the reasonable charges and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
Bankruptcy Law.

Section 8.07   Replacement of Trustee

           A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section 8.07.

           The Trustee may resign and be discharged from the trust hereby
created by so notifying the Company. The Holders of a majority in principal
amount of the then outstanding Notes may remove the Trustee by so notifying the
Trustee and the Company. The Company may remove the Trustee if:

           (1) the Trustee fails to comply with Section 310(b) of the TIA;

           (2) the Trustee is adjudged a bankrupt or an insolvent or an order
for relief is entered with respect to the Trustee under any Bankruptcy Law;

           (3) a Custodian or public officer takes charge of the Trustee or its
property; or

           (4) the Trustee becomes incapable of acting.

           If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

           If a successor Trustee does not take office within 30 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the then outstanding Notes may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

           If the Trustee fails to comply with Section 310 of the TIA, any
Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

           A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property
held by it as Trustee to the successor Trustee, subject to the Lien provided for
in Section 8.06. Notwithstanding replacement of the Trustee pursuant to this
Section 8.07, the Company's obligations under Section 8.06 shall continue for
the benefit of the retiring Trustee.

Section 8.08   Successor Trustee by Merger, etc.

           Subject to Section 8.09, if the Trustee consolidates, merges or
converts into, or transfers all or substantially all of its corporate trust
business to, another corporation, the successor corporation without any further
act shall be the successor Trustee.

Section 8.09   Eligibility; Disqualification

<PAGE>
 
           There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, shall be authorized
under such laws to exercise corporate trust power, shall be subject to
supervision or examination by federal or state (or the District of Columbia)
authority and shall have a combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

Section 8.10   Reports by Trustee to Holders

           To the extent required by TIA ss. 313(a), within 60 days after May 15
of each year commencing with 1997 and for as long as there are Notes outstanding
hereunder, the Trustee shall mail to each Holder the Company's brief report
dated as of such date that complies with TIA ss. 313(a). The Trustee also shall
comply with TIA ss. 313(b), (c) and (d). A copy of such report at the time of
its mailing to Holders shall be filed with the SEC, if required, and each stock
exchange, if any, on which the Notes are listed.

           The Company shall promptly notify the Trustee if the Notes become
listed on any national securities exchange and the Trustee shall comply with
Section 313(d) of the TIA.

                                   ARTICLE 9

                            DISCHARGE OF INDENTURE

Section 9.01   Termination of Company's Obligations

           This Indenture shall cease to be of further effect (except that the
Company's obligations under Section 8.06 and the Trustee's and Paying Agent's
obligations under Section 9.03 shall survive) when all outstanding Notes
theretofore authenticated and issued have been delivered (other than destroyed,
lost or stolen Notes that have been replaced or paid) to the Trustee for
cancellation and the Company has paid all sums payable hereunder. In addition,
the Company may terminate all of its obligations under this Indenture if:

           (1) the Company irrevocably deposits in trust with the Trustee or, at
the option of the Trustee, with a trustee satisfactory to the Trustee and the
Company under the terms of an irrevocable trust agreement in form and substance
satisfactory to the Trustee, money or U.S. Government Obligations sufficient to
pay principal of, premium, if any, and interest on the Notes to maturity and to
pay all other sums payable by it hereunder; provided that (i) the trustee of the
irrevocable trust shall have been irrevocably instructed to pay such money or
the proceeds of such U.S. Government Obligations to the Trustee and (ii) the
Trustee shall have been irrevocably instructed to apply such money or the
proceeds of such U.S. Government Obligations to the payment of said principal,
premium and interest with respect to the Notes;

           (2) the Company delivers to the Trustee an Officers' Certificate
stating that all conditions precedent to satisfaction and discharge of this
Indenture have been complied with, and an Opinion of Counsel to the same effect;

           (3) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit; and

           (4) the Company shall have delivered to the Trustee an Opinion of
Counsel from nationally recognized counsel acceptable to the Trustee or a tax
ruling to the effect that the Holders of the Notes will not recognize income,
gain or loss for federal income tax purposes as a result of the Company's
exercise of its option under this Section 9.01 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 if such option had not been exercised.

In such event, this Indenture shall cease to be of further effect (except as
provided in the next succeeding paragraph), and the Trustee, on demand of the
Company, shall execute proper instruments acknowledging confirmation of and
discharge under this Indenture.

           However, the Company's obligations in Sections 2.03, 2.04, 2.05,
2.06, 5.01, 5.02, 8.06 and 8.07 and the Company's, the Trustee's and Paying
Agent's obligations in Section 9.03 shall survive until the Notes are no longer

<PAGE>
 
outstanding. Thereafter, only the Company's obligations in Section 8.06 and the
Trustee's and Paying Agent's obligations in Section 9.03 shall survive.

           After such irrevocable deposit made pursuant to this Section 9.01 and
satisfaction of the other conditions set forth herein, the Trustee upon request
shall acknowledge in writing the discharge of the Company's obligations under
this Indenture except for those surviving obligations specified above.

           In order to have money available on a payment date to pay principal
of, premium, if any, or interest on the Notes, the U.S. Government Obligations
shall be payable as to principal or interest on or before such payment date in
such amounts as will provide the necessary money. U.S. Government Obligations
shall not be callable at the issuer's option.

Section 9.02   Application of Trust Money

           The Trustee or a trustee satisfactory to the Trustee and the Company
shall hold in trust money or U.S. Government Obligations deposited with it
pursuant to Section 9.01. It shall apply the deposited money and the money from
U.S. Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of, premium, if any, and interest on the
Notes.

Section 9.03   Repayment to Company

           The Trustee and the Paying Agent shall promptly pay to the Company
upon written request any excess money or securities held by them at any time.

           The Trustee and the Paying Agent shall pay to the Company upon
written request any money held by them for the payment of principal, premium, if
any, or interest that remains unclaimed for two years after the date upon which
such payment shall have become due; provided, however, that the Company shall
have either caused notice of such payment to be mailed to each Holder entitled
thereto no less than 30 days prior to such repayment or within such period shall
have published such notice in a financial newspaper of general circulation
published in The City of New York. After payment to the Company, Holders
entitled to the money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another Person, and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

Section 9.04   Reinstatement

           If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with Section 9.01 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 9.01 until such
time as the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 9.01; provided, however, that
if the Company has made any payment of principal of, premium, if any, or
interest on any Notes because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent.

                                  ARTICLE 10
                                  AMENDMENTS

Section 10.01  Without Consent of Holders

           The Company and the Trustee may amend this Indenture or the Notes or
waive any provision hereof without the consent of any Holder:

           (1) to cure any ambiguity, defect or inconsistency;

<PAGE>
 
           (2) to comply with Section 6.01;
           (3) to provide for uncertificated Notes in addition to certificated
Notes;
           (4) to make any change that does not adversely affect the legal
rights hereunder of any Holder; 
           (5) to surrender any right or power herein conferred upon the
Company;           
           (6) to modify, eliminate or add to the provisions of this Indenture
to such extent as shall be necessary to effect the qualification of the
Indenture under the TIA, or under any similar federal statute hereafter enacted;
or           
           (7) to add or release any Guarantor pursuant to the terms of this
Indenture or the Guarantees.

           Upon the request of the Company, accompanied by a resolution of the
Board of Directors authorizing the execution of any such supplemental indenture,
and upon receipt by the Trustee of the documents described in Section 10.06, the
Trustee shall join with the Company in the execution of any supplemental
indenture authorized or permitted by the terms of this Indenture and make any
further appropriate agreements and stipulations that may be therein contained,
but the Trustee shall not be obligated to enter into any supplemental indenture
that affects its own rights, duties or immunities under this Indenture or
otherwise. After an amendment or waiver under this Section 10.01 becomes
effective, the Company shall mail to the Holders of each Note affected thereby a
notice briefly describing the amendment or waiver. Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture.

Section 10.02  With Consent of Holders

           Except as provided in this Section 10.02, the Company and the Trustee
may amend this Indenture or the Notes with the written consent (including
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 then
outstanding Notes.

           Upon the request of the Company, accompanied by a resolution of the
Board of Directors of the Company authorizing the execution of any such
supplemental indenture, and upon the filing with the Trustee of evidence of the
consent of the Holders as aforesaid, and upon receipt by the Trustee of the
documents described in Section 10.06, the Trustee shall join with the Company in
the execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

           It shall not be necessary for the consent of the Holders under this
Section 10.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

           The Holders of a majority in principal amount of the Notes then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes (including waivers obtained in
connection with a tender offer or exchange offer for Notes). However, without
the consent of each Holder affected, an amendment or waiver under this Section
10.02 may not:

           (1) reduce the amount of Notes whose Holders must consent to an
amendment, supplement or waiver; 
           (2) reduce the rate of or change the time for payment of interest,
including default interest, on any Note ; 
           (3) reduce the principal of or change the fixed maturity of any Note
or alter the provisions with respect to optional redemption or mandatory
repurchase of the Notes under this Indenture, including without limitation
purchases of Notes under Section 3.04;
           (4) make any Note payable in money other than that stated in the
Note;
           (5) make any change in Section 5.03, 7.04 or 7.07 or in this
paragraph of this Section 10.02; or

           The right of any Holder to participate in any consent required or

Section 10.03  Compliance with Trust Indenture Act

           Every amendment to this Indenture or the Notes shall comply in form
and substance with the TIA as then in effect.

Section 10.04  Revocation and Effect of Consents

           Until an amendment (which includes any supplement) or waiver becomes
effective, a consent to it by a Holder of a Note is a continuing consent by the
Holder and every subsequent Holder of a Note or portion of a Note that evidences
the same debt as the consenting Holder's Note, even if notation of the consent
is not made on any Note. However, any such Holder or subsequent Holder may
revoke the consent as to his or her Note or portion of a Note if the Trustee
receives written notice of revocation before the date the amendment or waiver
becomes effective. An amendment or waiver becomes effective in accordance with
its terms and thereafter binds every Holder.

           The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment or
waiver. If the Company elects to fix a record date for such purpose, the record
date shall be fixed at (i) the later of 30 days prior to the first solicitation
of such consent or the date of the most recent list of Holders furnished to the
Trustee prior to such solicitation, or (ii) such other date as the Company shall
designate. If a record date is fixed, then notwithstanding the provisions of the
immediately preceding paragraph, those Persons who were Holders at such record
date (or their duly designated proxies), and only those Persons, shall be
entitled to consent to such amendment or waiver or to revoke any consent
previously given, whether or not such Persons continue to be Holders after such
record date. No consent shall be valid or effective for more than 90 days after
such record date unless consents from Holders of the principal amount of Notes
required hereunder for such amendment or waiver to be effective shall have also
been given and not revoked within such 90-day period.

           After an amendment or waiver becomes effective it shall bind every
Holder, unless it is of the type described in any of clauses (1) through (7) of
Section 10.02. In such case, the amendment or waiver shall bind each Holder of a
Note who has consented to it and every subsequent Holder of a Note that
evidences the same debt as the consenting Holder's Note.

Section 10.05  Notation on or Exchange of Notes

           The Trustee may place an appropriate notation about an amendment or
waiver on any Note thereafter authenticated. The Company in exchange for all
Notes may issue and the Trustee shall authenticate new Notes that reflect the
amendment or waiver.

Section 10.06  Trustee to Sign Amendments, etc.

           The Trustee shall sign any amendment or supplemental indenture
authorized pursuant to this Article 10 if the amendment does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does,
the Trustee may, but need not, sign it. In signing or refusing to sign such
amendment or supplemental indenture, the Trustee shall be entitled to receive
and, subject to Section 8.01, shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that such
amendment or supplemental indenture is authorized or permitted by this
Indenture, that it is not inconsistent herewith and that it will be valid and
binding upon the Company in accordance with its terms.

                             [REVERSE OF SECURITY]

                      12% SENIOR NOTE DUE 2003, SERIES A

           Certain capitalized terms used but not defined herein shall have the
meanings given to them in the Indenture under which this Note is issued.

           1. Interest. ICF Kaiser International, Inc., a Delaware corporation
(the "Company," which term shall include any Successor under the Indenture),
promises to pay interest on the principal amount of this Note at 12%, provided
that one percent (1%) additional interest (the "Additional Interest") is payable
on the Notes from the date of, and as provided in, the Indenture. The Company
files its financial results with the Securities and Exchange Commission on
quarterly and annual reports, and these reports include the Company's earnings
after deducting minority interests and before interest, taxes, depreciation, and
amortization calculated in accordance with generally accepted accounting
principles ("Earnings"). The Company measures its Earnings for trailing twelve
month periods, each period to end on the last day of a fiscal quarter and extend
no further than March 31, 1998 (each a "Quarterly Measurement Period"). If the
Company's Earnings equal or exceed $36 million for two consecutive Quarterly
Measurement Periods, then the Company is relieved of its obligation to pay any
future Additional Interest. However, if the Company's Earnings do not equal or
exceed $36 million for any subsequent Quarterly Measurement Period, up to and
including the Quarterly Measurement Period ending March 31, 1998, the Company is
obligated to commence paying Additional Interest until the Company's Earnings
again equal or exceed $36 million on a trailing twelve month basis calculated
quarterly. The Company will pay interest semiannually on June 30 and December 31
of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Notes will
accrue from the most recent date on which interest has been paid or, if no
interest has been paid, from the date of issuance; provided, that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
June 30, 1997. The Company shall pay interest on overdue principal from time to
time on demand at the rate of 1% per annum in excess of the interest rate then
in effect; it shall pay interest on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the same
rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

           2. Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the record date next preceding the Interest Payment
Date, even if such Notes are cancelled after such record date and on or before
such Interest Payment Date. Holders must surrender Notes to a Paying Agent to
collect principal payments. The Company will pay the principal of, premium, if
any, and interest on the Notes in money of the United States of America that at
the time of payment is legal tender for payment of public and private debts
("U.S. Legal Tender"). The Company, however, may pay such amounts by check
payable in such U.S. Legal Tender. It may mail an interest check to a Holder's
registered address.

           3. Paying Agent and Registrar. Initially, The Bank of New York (the
"Trustee") will act as Paying Agent and Registrar. The Company may change any
Paying Agent, Registrar or co-registrar without notice to any Holder. The
Company may act in any such capacity.

           4. Indenture and Guarantees. The Company issued the Notes under an
Indenture dated as of December 23, 1996 (the "Indenture") between the Company
and the Trustee. The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb), as in effect on the date of
execution of the Indenture until such time as the Indenture is qualified under
the TIA, and thereafter as in effect on the date on which the Indenture is
qualified under the TIA. The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms.
Capitalized and certain other terms used herein and not otherwise defined have
the meanings set forth in the Indenture. The Notes are unsecured general
obligations of the Company limited to $15,000,000 in aggregate principal amount.
Payment on each Note is guaranteed, jointly and severally, by the Guarantors
pursuant to Section 5.11 of the Indenture.

           5. Optional Redemption. The Notes may not be redeemed prior to
December 31, 1998, but will be redeemable at the option of the Company, in whole
or in part, at any time on or after December 31, 1998, at the following
redemption

                1999                                      106.4%

</TABLE> 

     If fewer than all of the Notes are to be redeemed at any time, selection of
the Notes to be redeemed will be made by the Trustee from among the outstanding
Notes on a pro rata basis, by lot or by any other method permitted in the
Indenture. Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder whose Notes are to be
redeemed at the registered address of such Holder. On and after the redemption
date, interest shall cease to accrue on the Notes or portions thereof called for
redemption.

6.   Offers to Repurchase.

     (a) Change of Control Offer. In accordance with the terms of the Indenture,
upon the occurrence of a Change of Control, the Company will be required to
offer (a "Change of Control Offer") to purchase all outstanding Notes at a
purchase price equal to 101% of the aggregate principal amount of the Notes,
plus accrued and unpaid interest to the date of purchase.

     A Holder of Notes may tender or refrain from tendering all or any portion
of his Notes at his discretion by completing the form entitled "OPTION OF HOLDER
TO ELECT PURCHASE" appearing below on this Note. Any portion of Notes tendered
must be in integral multiples of $1,000.

     (b) Asset Sale Offer. In accordance with the terms of the Indenture,
if the Company or any Restricted Subsidiary consummates an Asset Sale, the
Company will, under certain circumstances, be required to utilize a portion of
the net proceeds received from such Asset Sale to offer to purchase Notes at a
purchase price equal to 100% of the aggregate principal amount of the Notes plus
accrued interest to the date fixed for the purchase.

     A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below this Note. Any portion of Notes
tendered must be in integral multiples of $1,000.

     Subject to the provisions described above and compliance with Article
6 of the Indenture, the Company may sell or otherwise dispose of all or
substantially all of its assets to a Successor that assumes all of the Company's
obligations under the Notes and Indenture, and thereafter be discharged from
such obligations.

7.   Denominations, Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and 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.

8.   Persons Deemed Owners. The registered Holder of a Note may be treated as
its owner for all purposes.

<PAGE>
 
9.   Unclaimed Funds.  If funds for the payment of principal or interest remain
unclaimed for two years, the Trustee and the Paying Agent will repay the funds
to the Company at its request. After that, all liability of the Trustee and
Paying Agent with respect to such funds shall cease.

10.  Discharge.  The Company may be discharged from its obligations under the
Indenture and the Notes, except for certain provisions thereof, upon
satisfaction of certain conditions specified in the Indenture.

11.  Amendments and Waivers. Subject to certain exceptions, the Indenture or the
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 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 interest on or the principal of the Notes, or any
failure to comply with the provisions of the Indenture relating to a Change of
Control Offer (as defined in the Indenture)) 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 Notes then outstanding.
Without the consent of any Holder, the Company and the Trustee may amend or
supplement the Indenture or the Notes to cure any ambiguity, defect or
inconsistency; to provide for the assumption of the Company's obligations to
Holders in the case of a merger or acquisition; to provide for uncertificated
Notes in addition to or in place of certificated Notes; to make any change that
does not adversely affect the legal rights of any Holder; to surrender any right
or power conferred upon the Company in the Indenture or the Notes; or to modify,
eliminate or add to the provisions of the Indenture or the Notes to such extent
as shall be necessary to effect the qualification of the Indenture under the TIA
or under any similar federal statute hereafter enacted.

     The right of any Holder to participate in any consent required or sought
pursuant to any provision of the Indenture (and the obligation of the Company to
obtain any such consent otherwise required from such Holder) may be subject to
the requirement that such Holder shall have been the Holder of record of any
Notes with respect to which such consent is required or sought as of a date
identified by the Trustee or the Company in a notice furnished to Holder in
accordance with the terms of the Indenture.

     Without the consent of each Holder affected, the Company may not take
certain actions, including: (i) reduce the amount of Notes whose Holders must
consent to an amendment, supplement or waiver; (ii) reduce the rate of or change
the time for payment of interest, including default interest, on any Note; (iii)
reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to optional redemption or mandatory repurchase of the
Notes under the Indenture; (iv) make any Note payable in money other than that
stated in this Note; (v) make any change in certain provisions of the Indenture
regarding a Change of Control, a waiver of past Defaults and the rights of
Holders to receive payment; or (vi) waive a continuing Default or Event of
Default in the payment of principal of or interest on the Notes or that resulted
from a failure to comply with the Change of Control provisions of the Indenture.

12.  Restrictive Covenants. The Indenture contains certain covenants which,
among other things, limit: (i) the incurrence of additional Indebtedness by the
Company and Restricted Subsidiaries; (ii) the payment of dividends; (iii) the
repurchase of capital stock or subordinated indebtedness; (iv) the making of
certain other distributions, loans and investments; (v) the sale of assets and
the sale of the stock of Restricted Subsidiaries; (vi) the creation of
restrictions on the ability of Restricted Subsidiaries to pay dividends or make
other payments to the Company; and (vii) the ability of the Company and
Restricted Subsidiaries to enter into certain transactions with Affiliates or to
merge, consolidate or transfer substantially all assets. These restrictions are
subject to important qualifications and exceptions. The Company must report to
the Trustee on compliance with such limitations.

13.  Defaults and Remedies. Events of Default include: default in payment of
interest on the Notes for 30 days; default in payment of principal on the Notes;
failure by the Company for 60 days after notice to it to comply with any of its
other agreements in the Indenture or the Notes; certain defaults under other
Indebtedness; certain final judgments that remain undercharged; and certain
events of bankruptcy or insolvency. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be immediately due and
payable for an amount equal to 100% of the principal amount of the Notes plus
accrued interest to the date of payment, except that in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding
Notes become due and payable immediately without further action or notice.

<PAGE>
 
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it
enforces the Indenture or the Notes. Subject to certain limitations, Holders of
a majority in principal amount of the then outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing default (except a default in payment of
principal or interest) if it determines that withholding notice is in their
interests. The Company must furnish an annual compliance certificate to the
Trustee.

14.  Trustee Dealings with Company. The Trustee, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the
Company or its Affiliates, and may otherwise deal with the Company or its
Affiliates, as if it were not Trustee.

15.  No Recourse Against Others. A director, officer, employee or stockholder,
as such, of the Company shall not have any liability for any obligations of the
Company under the Notes or the Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation. Each Holder by accepting
a Note waives and releases all such liability. The waiver and release are part
of the consideration for the issuance of the Notes.

16.  Authentication. This Note shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent.

17.  Abbreviations. Customary abbreviations may be used in the name of a Holder
or an assignee, such as: TEN COM (-- tenants in common), TEN ENT (-- tenants by
the entireties), JT TEN (-- joint tenants with right of survivorship and not as
tenants in common), CUST (--Custodian), and U/G/M/A (-- Uniform Gifts to Minors
Act).

18.  CUSIP Numbers. Pursuant to a recommendation promulgated by the Commission
on Uniform Security Identification Procedures, the Company has caused CUSIP
Numbers to be printed on the Notes as a convenience to the Holders of the Notes.
No representation is made to the accuracy of such numbers as provided on the
Notes, and reliance may be placed only on the other identification numbers
printed thereon.

19.  Governing Law. THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAW.

20.  Registration Rights. Pursuant to the Registration Rights Agreement, the
Company will be obligated upon the occurrence of certain events to consummate an
exchange offer pursuant to which the Holders of the Series A Notes shall have
the right to exchange the Series A Notes for the Company's 12% Senior Notes due
2003, Series B, which have been registered under the Securities Act, in like
principal amount and having terms identical in all material respects as the
Series A Notes. The Holders shall be entitled to receive certain additional
interest payments in the event such exchange offer is not consummated and upon
certain other conditions, all pursuant to and in accordance with the terms of
the Registration Rights Agreement.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Request may be made to:

                              [REVERSE OF SECURITY]
                       12% SENIOR NOTE DUE 2003, SERIES B

        Certain capitalized terms used but not defined herein shall have the
meanings given to them in the Indenture under which this Note is issued.


1.      Interest. ICF Kaiser International, Inc., a Delaware corporation (the
"Company," which term shall include any Successor under the Indenture), promises
to pay interest on the principal amount of this Note at 12% provided that one
percent (1%) additional interest (the "Additional Interest") is payable on the
Notes from the date of, and as provided in, the Indenture. The Company files its
financial results with the Securities and Exchange Commission on quarterly and
annual reports, and these reports include the Company's earnings after deducting
minority interests and before interest, taxes, depreciation, and amortization
calculated in accordance with generally accepted accounting principles
("Earnings"). The Company measures its Earnings for trailing twelve month
periods, each period to end on the last day of a fiscal quarter and extend no
further than March 31, 1998 (each a "Quarterly Measurement Period"). If the
Company's Earnings equal or exceed $36 million for two consecutive Quarterly
Measurement Periods, then the Company is relieved of its obligation to pay any
future Additional Interest. However, if the Company's Earnings do not equal or
exceed $36 million for any subsequent Quarterly Measurement Period, up to and
including the Quarterly Measurement Period ending March 31, 1998, the Company is
obligated to commence paying Additional Interest until the Company's Earnings
again equal or exceed $36 million on a trailing twelve month basis calculated
quarterly. The Company will pay interest semiannually on June 30 and December 31
of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Notes will
accrue from the most recent date on which interest has been paid or, if no
interest has been paid, from the date of issuance; provided, that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
June 30, 1997. The Company shall pay interest on overdue principal from time to
time on demand at the rate of 1% per annum in excess of the interest rate then
in effect; it shall pay interest on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the same
rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

2.      Method of Payment. The Company will pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders of Notes at the
close of business on the record date next preceding the Interest Payment Date,
even if such Notes are cancelled after such record date and on or before such
Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Company will pay the principal of, premium, if any, and
interest on the Notes in money of the United States of America that at the time
of payment is legal tender for payment of public and private debts ("U.S. Legal
Tender"). The Company, however, may pay such amounts by check payable in such
U.S. Legal Tender. It may mail an interest check to a Holder's registered
address.

3.      Paying Agent and Registrar. Initially, The Bank of New York (the
"Trustee") will act as Paying Agent and Registrar. The Company may change any
Paying Agent, Registrar or co-registrar without notice to any Holder. The
Company may act in any such capacity.

4.      Indenture and Guarantees. The Company issued the Notes under an
Indenture dated as of December 23, 1996 (the "Indenture") between the Company
and the Trustee. The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb), as in effect on the date of
execution of the Indenture until such time as the Indenture is qualified under
the TIA, and thereafter as in effect on the date on which the Indenture is
qualified under the TIA. The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms.
Capitalized and certain other terms used herein and not otherwise defined have
the meanings set forth in the Indenture. The Notes are unsecured general
obligations of the Company limited to $15,000,000 in aggregate principal amount.
Payment on each Note is guaranteed, jointly and severally, by the Guarantors
pursuant to Section 5.11 of the Indenture.
<PAGE>
 
5.      Optional Redemption. The Notes may not be redeemed prior to December 31,
1998, but will be redeemable at the option of the Company, in whole or in part,
at any time on or after December 31, 1998, at the following redemption prices
(expressed as percentages of principal amount), together with accrued and unpaid
interest, if any, thereon to the redemption date, if redeemed during the
12-month period beginning December 31:

                                                 Optional
                 Year                        Redemption Price
                 ----                        ----------------
                                            
                 1998                              108.0%
                 1999                              106.4%
                 2000                              104.8%
                 2001                              103.2%
                 2002                              101.6%

        If fewer than all of the Notes are to be redeemed at any time, selection
of the Notes to be redeemed will be made by the Trustee from among the
outstanding Notes on a pro rata basis, by lot or by any other method permitted
in the Indenture. Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to
be redeemed at the registered address of such Holder. On and after the
redemption date, interest shall cease to accrue on the Notes or portions thereof
called for redemption.

6.      Offers to Repurchase.

        (a)     Change of Control Offer. In accordance with the terms of the
Indenture, upon the occurrence of a Change of Control, the Company will be
required to offer (a "Change of Control Offer") to purchase all outstanding
Notes at a purchase price equal to 101% of the aggregate principal amount of the
Notes, plus accrued and unpaid interest to the date of purchase.

        A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below on this Note. Any portion of Notes
tendered must be in integral multiples of $1,000.

        (b) Asset Sale Offer. In accordance with the terms of the Indenture,
if the Company or any Restricted Subsidiary consummates an Asset Sale, the
Company will, under certain circumstances, be required to utilize a portion of
the net proceeds received from such Asset Sale to offer to purchase Notes at a
purchase price equal to 100% of the aggregate principal amount of the Notes plus
accrued interest to the date fixed for the purchase.

        A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below this Note. Any portion of Notes
tendered must be in integral multiples of $1,000.

        Subject to the provisions described above and compliance with Article
6 of the Indenture, the Company may sell or otherwise dispose of all or
substantially all of its assets to a Successor that assumes all of the Company's
obligations under the Notes and Indenture, and thereafter be discharged from
such obligations.

        The Notes rank pari passu with the $125,000,000 12% Senior
Subordinated Notes due 2003 issued by the Company pursuant to an Indenture dated
as of January 11, 1994 between the Company and The Bank of New York as Trustee.

7. Denominations, Transfer, Exchange. The Notes are in registered form without
coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and 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.
<PAGE>
 
8.      Persons Deemed Owners. The registered Holder of a Note may be treated as
its owner for all purposes.

9.      Unclaimed Funds.  If funds for the payment of principal or interest
remain unclaimed for two years, the Trustee and the Paying Agent will repay the
funds to the Company at its request. After that, all liability of the Trustee
and Paying Agent with respect to such funds shall cease.

10.     Discharge.  The Company may be discharged from its obligations under the
Indenture and the Notes, except for certain provisions thereof, upon
satisfaction of certain conditions specified in the Indenture.

11.     Amendments and Waivers. Subject to certain exceptions, the Indenture or
the 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 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 interest on or the principal of the Notes, or any
failure to comply with the provisions of the Indenture relating to a Change of
Control Offer (as defined in the Indenture)) 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 Notes then outstanding.
Without the consent of any Holder, the Company and the Trustee may amend or
supplement the Indenture or the Notes to cure any ambiguity, defect or
inconsistency; to provide for the assumption of the Company's obligations to
Holders in the case of a merger or acquisition; to provide for uncertificated
Notes in addition to or in place of certificated Notes; to make any change that
does not adversely affect the legal rights of any Holder; to surrender any right
or power conferred upon the Company in the Indenture or the Notes; or to modify,
eliminate or add to the provisions of the Indenture or the Notes to such extent
as shall be necessary to effect the qualification of the Indenture under the TIA
or under any similar federal statute hereafter enacted.

        The right of any Holder to participate in any consent required or
sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Notes with respect to which such consent is required or sought as of a
date identified by the Trustee or the Company in a notice furnished to Holder in
accordance with the terms of the Indenture.

        Without the consent of each Holder affected, the Company may not take
certain actions, including: (i) reduce the amount of Notes whose Holders must
consent to an amendment, supplement or waiver; (ii) reduce the rate of or change
the time for payment of interest, including default interest, on any Note; (iii)
reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to optional redemption or mandatory repurchase of the
Notes under the Indenture; (iv) make any Note payable in money other than that
stated in this Note; (v) make any change in certain provisions of the Indenture
regarding a Change of Control, a waiver of past Defaults and the rights of
Holders to receive payment; or (vi) waive a continuing Default or Event of
Default in the payment of principal of or interest on the Notes or that resulted
from a failure to comply with the Change of Control provisions of the Indenture.

12.     Restrictive Covenants. The Indenture contains certain covenants which,
among other things, limit: (i) the incurrence of additional Indebtedness by the
Company and Restricted Subsidiaries; (ii) the payment of dividends; (iii) the
repurchase of capital stock or subordinated indebtedness; (iv) the making of
certain other distributions, loans and investments; (v) the sale of assets and
the sale of the stock of Restricted Subsidiaries; (vi) the creation of
restrictions on the ability of Restricted Subsidiaries to pay dividends or make
other payments to the Company; and (vii) the ability of the Company and
Restricted Subsidiaries to enter into certain transactions with Affiliates or to
merge, consolidate or transfer substantially all assets. These restrictions are
subject to important qualifications and exceptions. The Company must report to
the Trustee on compliance with such limitations.

13.     Defaults and Remedies. Events of Default include: default in payment of
interest on the Notes for 30 days; default in payment of principal on the Notes;
failure by the Company for 60 days after notice to it to comply with any of its
other agreements in the Indenture or the Notes; certain defaults under other
Indebtedness; certain final judgments that remain undercharged; and certain
events of bankruptcy or insolvency. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be immediately due and
payable for an amount equal to 100% of the principal amount of the Notes plus
<PAGE>
 
accrued interest to the date of payment, except that in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding
Notes become due and payable immediately without further action or notice.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it
enforces the Indenture or the Notes. Subject to certain limitations, Holders of
a majority in principal amount of the then outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing default (except a default in payment of
principal or interest) if it determines that withholding notice is in their
interests. The Company must furnish an annual compliance certificate to the
Trustee.

14.     Trustee Dealings with Company. The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not Trustee.

15.     No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. Each
Holder by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for the issuance of the Notes.

16.     Authentication. This Note shall not be valid until authenticated by the
manual signature of the Trustee or an authenticating agent.

17.     Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (-- tenants in common), TEN ENT (--
tenants by the entireties), JT TEN (-- joint tenants with right of survivorship
and not as tenants in common), CUST (--Custodian), and U/G/M/A (-- Uniform Gifts
to Minors Act).

18.     CUSIP Numbers. Pursuant to a recommendation promulgated by the
Commission on Uniform Security Identification Procedures, the Company has caused
CUSIP Numbers to be printed on the Notes as a convenience to the Holders of the
Notes. No representation is made to the accuracy of such numbers as provided on
the Notes, and reliance may be placed only on the other identification numbers
printed thereon.

19.     Governing Law. THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAW.

        The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Request may be made to:

Ladies and Gentlemen:

     In connection with our proposed purchase of 12% Senior Notes due 2003,
Series A, or 12% Senior Notes due 2003, Series B (the "Notes"), of the Company,
we confirm that:

1.     We have received such information as we deem necessary in order to make
our investment decision.

2.     We understand that any subsequent transfer of the Notes is subject to
certain restrictions and conditions set forth in the Indenture and the
undersigned agrees to be bound by, and not to resell, pledge or otherwise
transfer the Notes except in compliance with, such restrictions and conditions
and the Securities Act of 1933, as amended (the "Securities Act").

3.     We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes may not be offered or
sold within the United States or to, or for the account or benefit of, U.S.
persons except as permitted in the following sentence. We agree, on our own
behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Notes, we will do so only (A) to the Company
or any subsidiary thereof, (B) inside the United States in accordance with Rule
144A under the Securities Act to a "qualified institutional buyer" (as defined
therein), (C) inside the United States to an institutional "accredited investor"
(as defined below) that, prior to such transfer, furnishes (or has furnished on
its behalf by a U.S. broker-dealer) to the Trustee a signed letter substantially
in the form hereof, (D) outside the United States in accordance with Regulation
S under the Securities Act, (E) pursuant to the exemption from registration
provided by Rule 144 under the Securities Act (if available) or (F) pursuant to
an effective registration statement under the Securities Act, and we further
agree to provide to any person purchasing Notes from us a notice advising such
purchaser that resales of the Notes are restricted as stated herein.

4.     We understand that, on any proposed resale of Notes, we will be required
to furnish to the Trustee and the Company, such certification, legal opinions
and other information as the Trustee and the Company may reasonably require to
confirm that the proposed sale complies with the foregoing restrictions.  We
further understand that the Notes purchased by us will bear a legend to the
foregoing effect.

5.     We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Notes, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or their investment, as the case may be.
<PAGE>
 
6.     We are acquiring the Notes purchased by us for our account or for one or
more accounts (each of which is an institutional "accredited investor") as to
each of which we exercise sole investment discretion.

irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceeding or official inquiry with respect

                      12% SENIOR NOTE DUE 2003, SERIES A

          Certain capitalized terms used but not defined herein shall have the
meanings given to them in the Indenture under which this Note is issued.

          1.    Interest.  ICF Kaiser International, Inc., a Delaware
corporation (the "Company," which term shall include any Successor under the
Indenture), promises to pay interest on the principal amount of this Note at
12%, provided that one percent (1%) additional interest (the "Additional
Interest") is payable on the Notes from the date of, and as provided in, the
Indenture.  The Company files its financial results with the Securities and
Exchange Commission on quarterly and annual reports, and these reports include
the Company's earnings after deducting minority interests and before interest,
taxes, depreciation, and amortization calculated in accordance with generally
accepted accounting principles ("Earnings").  The Company measures its Earnings
for trailing twelve month periods, each period to end on the last day of a
fiscal quarter and extend no further than March 31, 1998 (each a "Quarterly
Measurement Period").  If the Company's Earnings equal or exceed $36 million for
two consecutive Quarterly Measurement Periods, then the Company is relieved of
its obligation to pay any future Additional Interest.  However, if the Company's
Earnings do not equal or exceed $36 million for any subsequent Quarterly
Measurement Period, up to and including the Quarterly Measurement Period ending
March 31, 1998, the Company is obligated to commence paying Additional Interest
until the Company's Earnings again equal or exceed $36 million on a trailing
twelve month basis calculated quarterly.  The Company will pay interest
semiannually on June 30 and December 31 of each year, or if any such day is not
a Business Day, on the next succeeding Business Day (each an "Interest Payment
Date").  Interest on the Notes will accrue from the most recent date on which
interest has been paid or, if no interest has been paid, from the date of
issuance; provided, that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to on
the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; provided, further, that
the first Interest Payment Date shall be June 30, 1997.  The Company shall pay
interest on overdue principal from time to time on demand at the rate of 1% per
annum in excess of the interest rate then in effect; it shall pay interest on
overdue installments of interest (without regard to any applicable grace
periods) from time to time on demand at the same rate to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

          2.    Method of Payment.  The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the record date next preceding the Interest Payment
Date, even if such Notes are cancelled after such record date and on or before
such Interest Payment Date.  Holders must surrender Notes to a Paying Agent to
collect principal payments.  The Company will pay the principal of, premium, if
any, and interest on the Notes in money of the United States of America that at
the time of payment is legal tender for payment of public and private debts
("U.S. Legal Tender").  The Company, however, may pay such amounts by check
payable in such U.S. Legal Tender.  It may mail an interest check to a Holder's
registered address.

          3.    Paying Agent and Registrar.  Initially, The Bank of New York
(the "Trustee") will act as Paying Agent and Registrar.  The Company may change
any Paying Agent, Registrar or co-registrar without notice to any Holder.  The
Company may act in any such capacity.

          4.    Indenture and Guarantees.  The Company issued the Notes under an
Indenture dated as of December 23, 1996 (the "Indenture") between the Company
and the Trustee.  The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code (S)(S)77aaa-77bbbb), as in effect on the date of
execution of the Indenture until such time as the Indenture is qualified under
the TIA, and thereafter as in effect on the date on which the Indenture is
qualified under the TIA. The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms.
Capitalized and certain other terms used herein and not otherwise defined have
the meanings set forth in the Indenture. The Notes are unsecured general
obligations of the Company limited to $15,000,000 in aggregate principal amount.
Payment on each Note is guaranteed, jointly and severally, by the Guarantors
pursuant to Section 5.11 of the Indenture.

          5.    Optional Redemption.  The Notes may not be redeemed prior to
December 31, 1998, but will be redeemable at the option of the Company, in whole
or in part, at any time on or after December 31, 1998, at the following
redemption prices (expressed as percentages of principal amount), together with
accrued and unpaid interest, if any, thereon to the redemption date, if redeemed
during the 12-month period beginning December 31:

               2002                      101.6%

</TABLE> 
          If fewer than all of the Notes are to be redeemed at any time,
selection of the Notes to be redeemed will be made by the Trustee from among the
outstanding Notes on a pro rata basis, by lot or by any other method permitted
in the Indenture.  Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to
be redeemed at the registered address of such Holder.  On and after the
redemption date, interest shall cease to accrue on the Notes or portions thereof
called for redemption.

          6.    Offers to Repurchase.

                (a) Change of Control Offer. In accordance with the terms of the
Indenture, upon the occurrence of a Change of Control, the Company will be
required to offer (a "Change of Control Offer") to purchase all outstanding
Notes at a purchase price equal to 101% of the aggregate principal amount of the
Notes, plus accrued and unpaid interest to the date of purchase.

          A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below on this Note.  Any portion of Notes
tendered must be in integral multiples of $1,000.

                (b) Asset Sale Offer.  In accordance with the terms of the
Indenture, if the Company or any Restricted Subsidiary consummates an Asset
Sale, the Company will, under certain circumstances, be required to utilize a
portion of the net proceeds received from such Asset Sale to offer to purchase
Notes at a purchase price equal to 100% of the aggregate principal amount of the
Notes plus accrued interest to the date fixed for the purchase.

          A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below this Note.  Any portion of Notes
tendered must be in integral multiples of $1,000.

          Subject to the provisions described above and compliance with Article
6 of the Indenture, the Company may sell or otherwise dispose of all or
substantially all of its assets to a Successor that assumes all of the Company's
obligations under the Notes and Indenture, and thereafter be discharged from
such obligations.

          7.   Denominations, Transfer, Exchange.  The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000.  The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture.  The Registrar and 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.

          8.   Persons Deemed Owners.  The registered Holder of a Note may be
treated as its owner for all purposes.

                                  Reverse - 4
<PAGE>
 
          9.   Unclaimed Funds. If funds for the payment of principal or
interest remain unclaimed for two years, the Trustee and the Paying Agent will
repay the funds to the Company at its request. After that, all liability of the
Trustee and Paying Agent with respect to such funds shall cease. 

          10.  Discharge. The Company may be discharged from its obligations
under the Indenture and the Notes, except for certain provisions thereof, upon
satisfaction of certain conditions specified in the Indenture. 

          11.  Amendments and Waivers.  Subject to certain exceptions, the
Indenture or the 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 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 interest on or the principal of the Notes,
or any failure to comply with the provisions of the Indenture relating to a
Change of Control Offer (as defined in the Indenture)) 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 Notes
then outstanding.  Without the consent of any Holder, the Company and the
Trustee may amend or supplement the Indenture or the Notes to cure any
ambiguity, defect or inconsistency; to provide for the assumption of the
Company's obligations to Holders in the case of a merger or acquisition; to
provide for uncertificated Notes in addition to or in place of certificated
Notes; to make any change that does not adversely affect the legal rights of any
Holder; to surrender any right or power conferred upon the Company in the
Indenture or the Notes; or to modify, eliminate or add to the provisions of the
Indenture or the Notes to such extent as shall be necessary to effect the
qualification of the Indenture under the TIA or under any similar federal
statute hereafter enacted.

          The right of any Holder to participate in any consent required or
sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Notes with respect to which such consent is required or sought as of a
date identified by the Trustee or the Company in a notice furnished to Holder in
accordance with the terms of the Indenture.

          Without the consent of each Holder affected, the Company may not take
certain actions, including:  (i) reduce the amount of Notes whose Holders must
consent to an amendment, supplement or waiver; (ii) reduce the rate of or change
the time for payment of interest, including default interest, on any Note; (iii)
reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to optional redemption or mandatory repurchase of the
Notes under the Indenture; (iv) make any Note payable in money other than that
stated in this Note; (v) make any change in certain provisions of the Indenture
regarding a Change of Control, a waiver of past Defaults and the rights of
Holders to receive payment; or (vi) waive a continuing Default or Event of
Default in the payment of principal of or interest on the Notes or that resulted
from a failure to comply with the Change of Control provisions of the Indenture.

          12.  Restrictive Covenants.  The Indenture contains certain covenants
which, among other things, limit:  (i) the incurrence of additional Indebtedness
by the Company and Restricted Subsidiaries; (ii) the payment of dividends; (iii)
the repurchase of capital stock or subordinated indebtedness; (iv) the making of
certain other distributions, loans and investments; (v) the sale of assets and
the sale of the stock of Restricted Subsidiaries; (vi) the creation of
restrictions on the ability of Restricted Subsidiaries to pay dividends or make
other payments to the Company; and (vii) the ability of the Company and
Restricted Subsidiaries to enter into certain transactions with Affiliates or to
merge, consolidate or transfer substantially all assets.  These restrictions are
subject to important qualifications and exceptions.  The Company must report to
the Trustee on compliance with such limitations.

          13.  Defaults and Remedies.  Events of Default include:  default in
payment of interest on the Notes for 30 days; default in payment of principal on
the Notes; failure by the Company for 60 days after notice to it to comply with
any of its other agreements in the Indenture or the Notes; certain defaults
under other Indebtedness; certain final judgments that remain undercharged; and
certain events of bankruptcy or insolvency.  If an Event of Default occurs and
is continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be immediately due and
payable for an amount equal to 100% of the principal amount of the Notes plus
accrued interest to the date of payment, except that in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding
Notes become due and payable immediately without further action or notice.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture.  The Trustee may 

                                  Reverse - 5
<PAGE>
 
require indemnity satisfactory to it before it enforces the Indenture or the
Notes. Subject to certain limitations, Holders of a majority in principal amount
of the then outstanding Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders notice of any continuing
default (except a default in payment of principal or interest) if it determines
that withholding notice is in their interests. The Company must furnish an
annual compliance certificate to the Trustee.

          14.  Trustee Dealings with Company.  The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee.

          15.  No Recourse Against Others.  A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability.  The
waiver and release are part of the consideration for the issuance of the Notes.

          16.  Authentication.  This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

          17.  Abbreviations.  Customary abbreviations may be used in the name
of a Holder or an assignee, such as:  TEN COM (-- tenants in common), TEN ENT 
(-- tenants by the entireties), JT TEN (-- joint tenants with right of
survivorship and not as tenants in common), CUST (--Custodian), and U/G/M/A 
(--Uniform Gifts to Minors Act).

          18.  CUSIP Numbers.  Pursuant to a recommendation promulgated by the
Commission on Uniform Security Identification Procedures, the Company has caused
CUSIP Numbers to be printed on the Notes as a convenience to the Holders of the
Notes.  No representation is made to the accuracy of such numbers as provided on
the Notes, and reliance may be placed only on the other identification numbers
printed thereon.

          19.  Governing Law.  THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

          20.  Registration Rights.  Pursuant to the Registration Rights
Agreement, the Company will be obligated upon the occurrence of certain events
to consummate an exchange offer pursuant to which the Holders of the Series A
Notes shall have the right to exchange the Series A Notes for the Company's 12%
Senior Notes due 2003, Series B, which have been registered under the Securities
Act, in like principal amount and having terms identical in all material
respects as the Series A Notes.  The Holders shall be entitled to receive
certain additional interest payments in the event such exchange offer is not
consummated and upon certain other conditions, all pursuant to and in accordance
with the terms of the Registration Rights Agreement.

     The Guarantors (as defined in the Indenture referred to in the Note upon
which this notation is endorsed and each hereinafter referred to as a
"Guarantor," which term includes any successor to a Guarantor) have
unconditionally guaranteed (such guarantee by each Guarantor being referred to

and premium, if any, on any Note when and as the same shall come due and
payable, whether at the stated maturity thereof, by acceleration, redemption or
otherwise and (b) the full and prompt payment of any interest on any Note when

Indenture.

     No stockholder, officer, director or incorporator, as such, past, present

reason of his or its status as such stockholder, officer, director or
incorporator.

     The Guarantees shall not be valid or obligatory for any purpose until the
certificate of authentication on the Notes upon which the guarantees are noted

                      12% SENIOR NOTE DUE 2003, SERIES B


          Certain capitalized terms used but not defined herein shall have the
meanings given to them in the Indenture under which this Note is issued.

          1. Interest. ICF Kaiser International, Inc., a Delaware corporation
(the "Company," which term shall include any Successor under the Indenture),
promises to pay interest on the principal amount of this Note at 12% provided
that one percent (1%) additional interest (the "Additional Interest") is payable
on the Notes from the date of, and as provided in, the Indenture. The Company
files its financial results with the Securities and Exchange Commission on
quarterly and annual reports, and these reports include the Company's earnings
after deducting minority interests and before interest, taxes, depreciation, and
amortization calculated in accordance with generally accepted accounting
principles ("Earnings"). The Company measures its Earnings for trailing twelve
month periods, each period to end on the last day of a fiscal quarter and extend
no further than March 31, 1998 (each a "Quarterly Measurement Period"). If the
Company's Earnings equal or exceed $36 million for two consecutive Quarterly
Measurement Periods, then the Company is relieved of its obligation to pay any
future Additional Interest. However, if the Company's Earnings do not equal or
exceed $36 million for any subsequent Quarterly Measurement Period, up to and
including the Quarterly Measurement Period ending March 31, 1998, the Company is
obligated to commence paying Additional Interest until the Company's Earnings
again equal or exceed $36 million on a trailing twelve month basis calculated
quarterly. The Company will pay interest semiannually on June 30 and December 31
of each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Notes will
accrue from the most recent date on which interest has been paid or, if no
interest has been paid, from December 31, 1996; provided, that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
June 30, 1997. The Company shall pay interest on overdue principal from time to
time on demand at the rate of 1% per annum in excess of the interest rate then
in effect; it shall pay interest on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the same
rate to the extent lawful. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

          2. Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the record date next preceding the Interest Payment
Date, even if such Notes are cancelled after such record date and on or before
such Interest Payment Date. Holders must surrender Notes to a Paying Agent to
collect principal payments. The Company will pay the principal of, premium, if
any, and interest on the Notes in money of the United States of America that at
the time of payment is legal tender for payment of public and private debts
("U.S. Legal Tender"). The

                                  Reverse - 1
<PAGE>
 
Company, however, may pay such amounts by check payable in such U.S. Legal
Tender. It may mail an interest check to a Holder's registered address.

          3. Paying Agent and Registrar. Initially, The Bank of New York (the
"Trustee") will act as Paying Agent and Registrar. The Company may change any
Paying Agent, Registrar or co-registrar without notice to any Holder. The
Company may act in any such capacity.

          4. Indenture and Guarantees. The Company issued the Notes under an
Indenture dated as of December 23, 1996 (the "Indenture") between the Company
and the Trustee. The terms of the Notes include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code (S)(S) 77aaa-77bbbb), as in effect on the date of
execution of the Indenture until such time as the Indenture is qualified under
the TIA, and thereafter as in effect on the date on which the Indenture is
qualified under the TIA. The Notes are subject to all such terms, and Holders
are referred to the Indenture and such Act for a statement of such terms.
Capitalized and certain other terms used herein and not otherwise defined have
the meanings set forth in the Indenture. The Notes are unsecured general
obligations of the Company limited to $15,000,000 in aggregate principal amount.
Payment on each Note is guaranteed, jointly and severally, by the Guarantors
pursuant to Section 5.11 of the Indenture.

          5. Optional Redemption. The Notes may not be redeemed prior to
December 31, 1998, but will be redeemable at the option of the Company, in whole
or in part, at any time on or after December 31, 1998, at the following
redemption prices (expressed as percentages of principal amount), together with
accrued and unpaid interest, if any, thereon to the redemption date, if redeemed
during the 12-month period beginning December 31:

                                         Optional
               Year                   Redemption Price
               ----                   ----------------

               1998                      108.0%
               1999                      106.4%
               2000                      104.8%
               2001                      103.2%
               2002                      101.6%

          If fewer than all of the Notes are to be redeemed at any time,
selection of the Notes to be redeemed will be made by the Trustee from among the
outstanding Notes on a pro rata basis, by lot or by any other method permitted
in the Indenture. Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to
be redeemed at the registered address of such Holder. On and after the
redemption date, interest shall cease to accrue on the Notes or portions thereof
called for redemption.

          6.  Offers to Repurchase.

              (a) Change of Control Offer. In accordance with the terms of the
Indenture, upon the occurrence of a Change of Control, the Company will be
required to offer (a "Change of Control Offer") to purchase all outstanding
Notes at a purchase price equal to 101% of the aggregate principal amount of the
Notes, plus accrued and unpaid interest to the date of purchase.

          A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below on this Note. Any portion of Notes
tendered must be in integral multiples of $1,000.

              (b) Asset Sale Offer. In accordance with the terms of the
Indenture, if the Company or any Restricted Subsidiary consummates an Asset
Sale, the Company will, under certain circumstances, be required to utilize a
portion of the net proceeds received from such Asset Sale to offer to purchase
Notes at a purchase price equal to 100% of the aggregate principal amount of the
Notes plus accrued interest to the date fixed for the purchase.

          A Holder of Notes may tender or refrain from tendering all or any
portion of his Notes at his discretion by completing the form entitled "OPTION
OF HOLDER TO ELECT PURCHASE" appearing below this Note. Any portion of Notes
tendered must be in integral multiples of $1,000.

          Subject to the provisions described above and compliance with Article
6 of the Indenture, the Company may sell or otherwise dispose of all or
substantially all of its assets to a Successor that assumes all of the Company's
obligations under the Notes and Indenture, and thereafter be discharged from
such obligations.

          7.  Denominations, Transfer, Exchange. The Notes are in registered
form without coupons in denominations of $1,000 and integral multiples of
$1,000. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and 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.

          8.  Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes.

                                  Reverse - 3
<PAGE>
 
          9. Unclaimed Funds. If funds for the payment of principal or interest
remain unclaimed for two years, the Trustee and the Paying Agent will repay the
funds to the Company at its request. After that, all liability of the Trustee
and Paying Agent with respect to such funds shall cease.

          10. Discharge. The Company may be discharged from its obligations
under the Indenture and the Notes, except for certain provisions thereof, upon
satisfaction of certain conditions specified in the Indenture.

          11. Amendments and Waivers. Subject to certain exceptions, the
Indenture or the 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 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 interest on or the principal of the Notes,
or any failure to comply with the provisions of the Indenture relating to a
Change of Control Offer (as defined in the Indenture)) 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 Notes
then outstanding. Without the consent of any Holder, the Company and the Trustee
may amend or supplement the Indenture or the Notes to cure any ambiguity, defect
or inconsistency; to provide for the assumption of the Company's obligations to
Holders in the case of a merger or acquisition; to provide for uncertificated
Notes in addition to or in place of certificated Notes; to make any change that
does not adversely affect the legal rights of any Holder; to surrender any right
or power conferred upon the Company in the Indenture or the Notes; or to modify,
eliminate or add to the provisions of the Indenture or the Notes to such extent
as shall be necessary to effect the qualification of the Indenture under the TIA
or under any similar federal statute hereafter enacted.

          The right of any Holder to participate in any consent required or
sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Notes with respect to which such consent is required or sought as of a
date identified by the Trustee or the Company in a notice furnished to Holder in
accordance with the terms of the Indenture.

          Without the consent of each Holder affected, the Company may not take
certain actions, including: (i) reduce the amount of Notes whose Holders must
consent to an amendment, supplement or waiver; (ii) reduce the rate of or change
the time for payment of interest, including default interest, on any Note; (iii)
reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to optional redemption or mandatory repurchase of the
Notes under the Indenture; (iv) make any Note payable in money other than that
stated in this Note; (v) make any change in certain provisions of the Indenture
regarding a Change of Control, a waiver of past Defaults and the rights of
Holders to receive payment; or

                                  Reverse - 4
<PAGE>
 
(vi) waive a continuing Default or Event of Default in the payment of principal
of or interest on the Notes or that resulted from a failure to comply with the
Change of Control provisions of the Indenture.

          12. Restrictive Covenants. The Indenture contains certain covenants
which, among other things, limit: (i) the incurrence of additional Indebtedness
by the Company and Restricted Subsidiaries; (ii) the payment of dividends; (iii)
the repurchase of capital stock or subordinated indebtedness; (iv) the making of
certain other distributions, loans and investments; (v) the sale of assets and
the sale of the stock of Restricted Subsidiaries; (vi) the creation of
restrictions on the ability of Restricted Subsidiaries to pay dividends or make
other payments to the Company; and (vii) the ability of the Company and
Restricted Subsidiaries to enter into certain transactions with Affiliates or to
merge, consolidate or transfer substantially all assets. These restrictions are
subject to important qualifications and exceptions. The Company must report to
the Trustee on compliance with such limitations.

          13. Defaults and Remedies. Events of Default include: default in
payment of interest on the Notes for 30 days; default in payment of principal on
the Notes; failure by the Company for 60 days after notice to it to comply with
any of its other agreements in the Indenture or the Notes; certain defaults
under other Indebtedness; certain final judgments that remain undercharged; and
certain events of bankruptcy or insolvency. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be immediately due and
payable for an amount equal to 100% of the principal amount of the Notes plus
accrued interest to the date of payment, except that in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding
Notes become due and payable immediately without further action or notice.
Holders may not enforce the Indenture or the Notes except as provided in the
Indenture. The Trustee may require indemnity satisfactory to it before it
enforces the Indenture or the Notes. Subject to certain limitations, Holders of
a majority in principal amount of the then outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing default (except a default in payment of
principal or interest) if it determines that withholding notice is in their
interests. The Company must furnish an annual compliance certificate to the
Trustee.

          14. Trustee Dealings with Company. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not Trustee.

          15. No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. Each
Holder by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for the issuance of the Notes.

          16. Authentication. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

          17. Abbreviations. Customary abbreviations may be used in the name of
a Holder or an assignee, such as: TEN COM (-- tenants in common), TEN ENT (--
tenants by the entireties), JT TEN (-- joint tenants with right of survivorship
and not as tenants in common), CUST (--Custodian), and U/G/M/A (-- Uniform Gifts
to Minors Act).

          18. CUSIP Numbers. Pursuant to a recommendation promulgated by the
Commission on Uniform Security Identification Procedures, the Company has caused
CUSIP Numbers to be printed on the Notes as a convenience to the Holders of the
Notes. No representation is made to the accuracy of such numbers as provided on
the Notes, and reliance may be placed only on the other identification numbers
printed thereon.

          19. Governing Law. THIS NOTE AND THE INDENTURE SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

without charge a copy of the Indenture. Request may be made to:

"Guarantor," which term includes any successor to a Guarantor) have
unconditionally guaranteed (such guarantee by each Guarantor being referred to

                          ORIGINAL ISSUE OF WARRANTS

Section 2.01  Form of Warrant Certificates

          The Warrant Certificates (a) shall be issued in registered form only
and substantially in the form attached hereto as Exhibit A, (b) shall be dated
the date of issuance thereof (whether upon initial issuance, registration of
transfer, exchange or replacement), (c) shall show the date of countersignature
and (d) shall have such legends and endorsements, each as provided by the
Company, typed, stamped, printed, lithographed or engraved thereon as the
Company may deem appropriate and as are not inconsistent with the provisions of
this Agreement, or as may be required to comply with any law or with any rule or
regulation pursuant thereto or with any rule or regulation of any securities
exchange on which the Warrant may be listed, or to conform to customary usage,
including, without limitation, the Private Placement Legend set forth on the
form of face of Warrant Certificate attached hereto as Exhibit A.  The Warrant
Certificates shall be in a format and in a form reasonably satisfactory to the
Warrant Agent.

          Warrants offered and sold in reliance on Rule 144A and to
Institutional Accredited Investors shall be issued initially in the form of one
or more permanent Global Warrants in registered form, substantially in the form
set forth in Exhibit A, deposited with the Warrant Agent, as custodian for the
Depositary, and shall bear the legend set forth on Exhibit B.  The aggregate
number of Warrants represented by any Global Warrant may from time to time be
increased or decreased by adjustments made on the records of the Warrant Agent,
as custodian for the Depositary, as hereinafter provided.

          Warrants offered and sold in offshore transactions in reliance on
Regulation S shall be issued in the form of certificated Warrants in registered
form, substantially in the form set forth in Exhibit A (the "Offshore Physical
Warrants").  Notes offered and sold in reliance on any other exemption from
registration under the Securities Act

                                      -3-
<PAGE>
 
other than as described in the preceding paragraph shall be issued, and Warrants
offered and sold in reliance on Rule 144A may be issued, in the form of
certificated Warrants in registered form in substantially the form set forth in
Exhibit A (the "U.S. Physical Warrants"). The Offshore Physical Warrants and the
U.S. Physical Warrants are sometimes collectively herein referred to as the
"Physical Warrants."

          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 105,000 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 thereupon countersign and
deliver such Warrant Certificates upon the order and at the direction of the
Company to the purchasers thereof on the date of issuance.  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 printed thereon.  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 issue and delivery thereof, 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
                     EXERCISE PRICE; EXERCISE OF WARRANTS
                     GENERALLY; NON-SURVIVING COMBINATION

Section 3.01  Exercise Price

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

Section 3.02  Exercise of Warrants

          Subject to the terms and conditions set forth herein, the Warrants
shall be exercisable at any time on or prior to the Expiration Date.

Section 3.03  Expiration of Warrants

                                      -4-
<PAGE>
 
          The Warrants shall terminate and become void as of the close of
business on the Expiration Date; provided, however, 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, however, that the
                                              --------  -------          
failure by the Company to give such notice as provided in this Section shall not
affect such termination and becoming void 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 thereof 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 therefor in accordance with this Article
III.

          In order for a Person having a beneficial interest in a Global Warrant
to exercise a Warrant, such Person must first exchange such beneficial interest
for a Physical Warrant in the manner provided in Section 5.02(d).

          If fewer than all of the Warrants represented by a Warrant Certificate
are surrendered, such Warrant Certificate shall be surrendered and, subject to
the provisions of Article V, a new Warrant Certificate of the same tenor and for
the number of Warrants that were not surrendered 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
thereupon promptly notify the Company, and the Warrant Agent will deliver or
cause to be delivered to or upon written order of any Holder appropriate
evidence of ownership of any shares of Underlying 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 thereof to the Warrant Agent
and to the Holders of Warrants, 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 thereof.  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 Underlying Common Stock if such Holder's Warrants
had been exercised immediately prior to such Non-Surviving Combination (or, if
applicable, the record date therefor).  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.

<PAGE>
 
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 after the date hereof, (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 or (iii) issue any shares of its capital stock in a reclassification
or reorganization of the Common Stock (any such issuance, subdivision,
combination, reclassification or reorganization being herein called a "Change of
Shares"), then (A) 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 (B) in
the case of (iii) above, paragraph (l) below shall apply.  An adjustment made
pursuant to clause (A) 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 after the date hereof, 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 herein 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
consideration, if any, received by the Company upon such Common Stock
Distribution, and the denominator of which shall be the product of (A) the total
number of shares of Common Stock outstanding (exclusive of any treasury shares)
immediately after such Common Stock Distribution multiplied by (B) 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 after the date hereof, 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 (any such
rights, warrants or options being herein 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 therein 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 herein 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) shall be less than the current market price per share of Common Stock
on the date of the issuance, sale, 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 thereafter 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, therefor.  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 after the date hereof, 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) shall be 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 thereafter
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,
therefor.  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 after the date hereof, 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

                                      -7-
<PAGE>
 
other rights to subscribe for or purchase any of the foregoing, then (A) 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 (X) the cash portion, if any, of such distribution
per share of Common Stock outstanding (exclusive of any treasury shares) on the
record date for such distribution plus (Y) 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 (B) 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 shorter of (i) the 20 consecutive trading days ending on the last
full trading day on the exchange or market specified in the second succeeding
sentence prior to the Time of Determination and (ii) the period commencing on
the date next succeeding the first public announcement of the issuance, sale,
distribution or granting in question through such last full trading day prior to
the Time of Determination.  The term "Time of Determination" as used herein
shall be the time and date of the earlier to occur of (A) the date as of which
the current market price is to be computed and (B) the last full trading day on
such exchange or market before the commencement of "ex-dividend" trading in the
Common Stock relating to 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 thereof 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 other than
cash, the amount of the consideration other than cash received by the Company in
respect thereof 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

                                      -8-
<PAGE>
 
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 hereunder (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, however, 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 forthwith 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 thereafter be 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 Securities, whether or not
exercised; provided, however, 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, thereafter 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, in either
case, which would

                                      -9-
<PAGE>
 
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 which provides that the price of the Common Stock purchased
for plan participants from the Company will be no less than 95% of the average
of the high and low sales prices of the Common Stock on the investment date or,
if no trading in the Common Stock occurs on such date, the next preceding date
on which trading occurred (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, the
current market price per share shall be the fair market value thereof as
determined in good faith by the Board of Directors of the Company; provided,
however, that clause (ii) of this paragraph (m) shall not apply to any such
grant or issuance if, after giving effect thereto, 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 herein
provided, 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 and the Warrant Agent 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 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 thereof 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 theretofore or thereafter
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

                                      -10-
<PAGE>
 
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 thereof), 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.

                                   ARTICLE V
                               WARRANT TRANSFERS

Section 5.01  Warrant Transfer Books

          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 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 herein provided.

          At the option of the Holder thereof, Warrant Certificates may be
exchanged at such office, upon payment of the charges hereinafter provided.
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 Physical Warrants.  When Physical
              ------------------------------------------

(ii)       to exchange such Physical Warrants for an equal number of
           Physical Warrants of other denominations,

the Warrant Agent shall register the transfer or make the exchange as requested
if the requirements under this Warrant Agreement as set forth in this Section
5.02 for such transactions are met; provided, however, that the Physical
                                    --------  -------

such transfer is in compliance with the Securities Act.

     (b) Restrictions on Exchange of a Physical Warrant for a Beneficial
         ---------------------------------------------------------------
Interest in a Global Warrant.  A Physical Warrant may not be exchanged for a
- ----------------------------                                                
beneficial interest in a Global Warrant except upon satisfaction of the
requirements set forth below.  Upon receipt by the Warrant Agent of a Physical
Warrant, duly endorsed or accompanied by appropriate instruments of transfer, in
form satisfactory to the Warrant Agent, together with:

(i)  certification, substantially in the form of Exhibit C hereto, that such
Physical Warrant is being transferred (A) to a Qualified Institutional Buyer,

then the Warrant Agent shall cancel such Physical Warrant 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 therein shall be effected through the
Depositary in accordance with this Warrant Agreement (including the restrictions
on transfer set forth herein) and the procedures of the Depositary therefor.

     (d) Transfer of a Beneficial Interest in a Global Warrant for a Physical
         --------------------------------------------------------------------
Warrant.
- ------- 

     (i) Any Person having a beneficial interest in a Global Warrant may upon
request exchange such beneficial interest for a Physical Warrant.  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 and, in the case of any such transfer or exchange of a beneficial
interest in Warrants the offer and sale of which have not been registered under
the Securities Act, the following additional information and documents:

(A)  if such beneficial interest is being transferred to the Person designated
by the Depositary as being the beneficial owner, a certification from such
Person to that effect (substantially in the form of Exhibit C hereto); or

                                      -12-
<PAGE>
 
(B)  if such beneficial interest is being transferred to a Qualified
Institutional Buyer in accordance with Rule 144A, a certification to that effect
(substantially in the form of Exhibit C hereto); or

(C)  if such beneficial interest is being transferred to an Institutional
Accredited Investor, delivery of a certification to that effect (substantially
in the form of Exhibit C hereto) and a Certificate for Institutional Accredited
Investors substantially in the form of Exhibit D hereto; or

(D)  if such beneficial interest is being transferred in reliance on Regulation
S, delivery of a certification to that effect (substantially in the form of
Exhibit C hereto) and a Transferee Certificate for Regulation S Transfers
substantially in the form of Exhibit E hereto and an Opinion of Counsel
reasonably satisfactory to the Company to the effect that such transfer is in
compliance with the Securities Act; or

(E)  if such beneficial interest is being transferred in reliance on Rule 144
under the Securities Act, delivery of a certification to that effect
(substantially in the form of Exhibit C hereto) and an Opinion of Counsel
reasonably satisfactory to the Company to the effect that such transfer is in
compliance with the Securities Act; or

(F)  if such beneficial interest is being transferred in reliance on another
exemption from the registration requirements of the Securities Act, a
certification to that effect (substantially in the form of Exhibit C hereto) and
an Opinion of Counsel reasonably satisfactory to the Company to the effect that
such transfer is in compliance with the Securities Act,

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 Physical Warrant.

     (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 Physical Warrants to the
Persons in whose names such Physical Warrants are so registered.

     (e)  Restrictions on Transfer and Exchange of Global Warrants.
          --------------------------------------------------------    
Notwithstanding any other provisions of this Warrant 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)  Private Placement Legend.  Upon the transfer, exchange or replacement
          ------------------------                                             
of Warrants, the Warrant Agent shall deliver only Warrants that bear the Private
Placement Legend unless, and the Warrant Agent is hereby authorized to deliver
Warrants without the Private Placement Legend if, (i) there is delivered to the
Warrant Agent an Opinion of Counsel reasonably satisfactory to the Company and
the Warrant Agent to the effect that neither such legend nor the related
restrictions on transfer are required in order to maintain compliance with the
provisions of the Securities Act or (ii) such Warrant has been sold pursuant to
an effective registration statement under the Securities Act.

     (g)  General.  By its acceptance of any Warrant bearing the Private
          -------                                                       
Placement Legend, each Holder of such a Warrant acknowledges the restrictions on
transfer of such Warrant set forth in this Warrant Agreement and in the Private
Placement Legend and agrees that it will transfer such Warrant only as provided
in this Warrant Agreement.

     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.

                                  ARTICLE VI
                                WARRANT HOLDERS

Section 6.01  No Voting Rights

          Prior to the exercise of the Warrants, no Holder of a Warrant
Certificate, 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 herein.

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 hereunder, including the right
to exercise, exchange or surrender for purchase such Holder's Warrants in the
manner provided in this Agreement.

                                  ARTICLE VII
                                 WARRANT AGENT

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 herein set forth, by all of which the Company and the
Holders of Warrants, by their acceptance thereof, shall be bound.  The Warrant
Agent shall not by countersigning Warrant Certificates or by any other act
hereunder be deemed to make any representation as to validity or authorization
of the Warrants or the Warrant Certificates (except as to its countersignature
thereon) 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 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 herein 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 hereunder 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

                                      -14-
<PAGE>
 
misconduct, but in its discretion the Warrant Agent may in lieu thereof 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 hereby vested in it or perform any duty hereunder 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 hereof, 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 hereunder 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.

          The Warrant Agent shall act solely as agent of the Company hereunder.
The Warrant Agent shall not be liable except for the failure to perform such
duties as are specifically set forth herein, 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
hereof.

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

          The Company agrees to pay to the Warrant Agent from time to time
compensation for all services rendered by it hereunder 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 claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder.  The
provisions of this Section 7.03 shall survive the termination of this Agreement.

Section 7.04  Warrant Agent May Hold Company Securities

                                      -15-
<PAGE>
 
          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 herein 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 herein. The
Warrant Agent may resign its duties and be discharged from all further duties
and liability hereunder (except liability arising as a result of the Warrant
Agent's own gross negligence, bad faith or willful misconduct) after giving
written notice to the Company. The Company may remove the Warrant Agent upon
written notice, and the Warrant Agent shall thereupon in like manner be
discharged from all further duties and liabilities hereunder, except as
aforesaid. 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 his 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 thereof 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 herein 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 thereof to the resigning or removed
Warrant Agent. Failure to give any notice provided for in this Section, however,
or any defect therein, 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.

                                 ARTICLE VIII
                           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 herein provided, such

                                      -16-
<PAGE>
 
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 herein
provided 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 thereof 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 certificates related
thereto transmitted to each holder pursuant to Section 4.02 hereof.

Section 8.02     Reports to Holders

          To the extent such documents are required to be sent by the Company to
the holders of its outstanding Common Stock, the Company shall file with the
Warrant Agent and provide Holders of Warrants, within 15 days after it files
them with the SEC, copies of its annual report and of the information, documents
and other reports (or copies of such portions of any of the foregoing as the SEC
may by rules and regulations prescribe) which the Company is required to file
with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.
Notwithstanding that the Company may not be required to remain subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall
continue to file with the SEC and, to the extent it is required to send such
documents to the holders of its outstanding Common Stock, provide the Warrant
Agent and the Holders of the Warrants with reports containing substantially the
same information as would have been required to be filed with the SEC and sent
to holders of its outstanding Common Stock had the Company continued to have
been subject to such reporting requirements; provided, however, that the Company
shall not be so obligated to file with the SEC if the SEC does not permit such
filings.  In such event, such reports shall be provided to the Warrant Agent and
Holders of Warrants at the times the Company would have been required to provide
such reports had it been subject to such reporting retirements.  Delivery of
such reports, information and documents to the Warrant Agent is for
informational purposes only and the Warrant Agent's receipt of such shall not
constitute constructive notice of any information contained therein, including
the Company's compliance with any of its covenants hereunder.

Section 8.03     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
Underlying Common Stock.

Section 8.04     Registration under the Securities Laws

          (a)    Mandatory Registration.  Not later than December 31, 1997, the
                 ----------------------                                        
Company shall file with the SEC, at the Company's expense, a registration
statement registering under the Securities Act for resale by the Holders all of
the Restricted Shares.  The Company shall use all reasonable efforts to cause
such registration statement to become effective as soon as possible thereafter
and to maintain such effectiveness continually until the first to occur of 
(i) December 31, 2001, (ii) the date all Restricted Shares covered by such
registration statement have been disposed of in accordance with such
registration statement, (iii) the date the Company has received a written
opinion of independent counsel, a copy of which will be provided to each Holder,
that all of the Restricted Shares are freely tradable without registration
pursuant to Rule 144 (or any successor thereto) under the Securities Act and
applicable state securities laws, or (iv) if no Warrants have been exercised on
or prior to the Expiration Date or such other date on which the Warrants
terminate and become void prior to the Expiration Date, the close of business on
the

                                      -17-
<PAGE>
 
Expiration Date or such other date on which the Warrants terminate and
become void prior to the Expiration Date.  Such registration statement will
include a plan of distribution permitting any reasonable method of resale by the
Holders of the Restricted Shares including resale in the public market, in
broker's transactions, or in privately negotiated transactions.  The Company
also will prepare and file promptly with the SEC, at the Company's expense, such
amendments and supplements to such registration statement and the prospectus
included in such registration statement as may be necessary to comply with the
provisions of the Securities Act.  The Holders shall provide the Company in
writing with such information about the Holders and the proposed plan of
distribution as the Company shall reasonably request for inclusion in the
registration statement.  The Company will provide to each Holder such number of
copies of such registration statement and of each amendment and supplement
thereto, such number of copies of the prospectus included in such registration
statement and each amendment and supplement thereto, and such other documents as
such Holder may reasonably request in order to facilitate the disposition of the
Restricted Shares owned by such Holder.  The Company shall, as expeditiously as
possible following the filing of such registration statement, use all reasonable
efforts to register or qualify the Restricted Shares covered by the registration
statement under the securities or Blue Sky laws of such states as the Holders
shall reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the Holders to consummate the public or other
disposition in each such jurisdiction of the Restricted Shares; provided,
                                                                -------- 
however, that the Company shall not be required in connection with this Section
- -------                                                                        
8.04 to qualify as a foreign corporation, subject itself to taxation or execute
a general consent to service of process in any jurisdiction.

          (b)    Indemnification.
                 --------------- 

          (i)    Indemnification by the Company.  The Company will, and hereby
                 ------------------------------                               
does, indemnify and hold harmless each Holder, its directors and officers, each
other person who participates as an underwriter, broker or dealer in the
offering or sale of Restricted Shares by such Holder and each other person, if
any, who controls such Holder or any such participating person within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act (each such person being sometimes referred to as an "Indemnified Holder"),
against any losses, claims, damages or liabilities, joint or several, to which
such Holder or any such director or officer or participating or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) arise out of or are based upon (x) any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Restricted Shares were registered under the Securities Act, any
preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, (y) any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein in the light of the circumstances under
which they were made not misleading or (z) any violation or alleged violation by
the Company of the Securities Act; and the Company will reimburse such Holder
and each such director, officer, participating person and controlling person for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided that the Company shall not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement, any such preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information relating to such
Indemnified Holder furnished to the Company through an instrument duly executed
by such Indemnified Holder expressly for use therein.  Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of such Holder or any such director, officer, participating person or
controlling person and shall survive the transfer of such securities by such
Holder.

          (ii)   Indemnification by the Holders of Restricted Shares.  Each 
                 ---------------------------------------------------        
Holder participating in the registration provided for in paragraph (a) above
shall indemnify and hold harmless (in the same manner and to the same extent as
set forth in clause (i)) the Company, each director of the Company, each officer
of the Company who shall sign such registration statement and each other person,
if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, with respect to any statement
in or omission from such registration statement, any preliminary prospectus,
final prospectus, or summary prospectus contained therein, or any amendment or
supplement thereto, if such statement or omission was made in reliance upon and
in conformity with written information relating to such Holders furnished to the
Company through an instrument duly 

                                      -18-
<PAGE>
 
executed by such Holder expressly for use in the preparation of such 
registration statement, preliminary prospectus, final prospectus or summary
prospectus contained therein, amendment or supplement. In no event, however,
shall the liability of any such Holder for indemnification under this paragraph
exceed the net proceeds received by the such Holder from the sale of such
Restricted Shares. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of the Company or any such
director, officer or controlling person and shall survive the transfer or such
securities by such Holder.

          (iii)  Notice of Claims, etc. Promptly after receipt by an  
                 ---------------------
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in clause (i) or (ii) of this paragraph (b), such
indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of
such action; provided, however, that the failure of any indemnified party to
             --------  -------
give notice as provided herein shall not relieve the indemnifying party of 
its obligations under the preceding clauses of this paragraph (b),
except to the extent that the indemnifying party is actually prejudiced by such
failure to give notice. In case any action is brought against an indemnified
party, the indemnifying party will be entitled to participate in and to assume
the defense of such action, jointly with any other indemnifying party to the
extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof; provided, however, that if the defendants in any such action
include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be defenses
available to it and/or other indemnified parties which are different from or
additional to those available to the indemnifying party, the indemnified party
or parties shall have the right to select separate counsel to assume such legal
defenses and to otherwise participate in the defense of such action on behalf of
the indemnified party or parties. No indemnifying party will consent to entry of
any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim or
litigation.

          (iv)   Contribution.  If for any reason the indemnification provided
                 ------------                                   
for in this paragraph (b) is unavailable to an indemnified party as contemplated
by this paragraph (b), then the indemnifying party in lieu of indemnification
shall contribute to the amount paid or payable by the indemnified party as a
result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect not only the relative benefits received by the
indemnified party and the indemnifying party, but also the relative fault of the
indemnified party and the indemnifying party, as well as any other relevant
equitable considerations, provided that no Holder shall be required to 
                          --------
contribute in an amount greater than the excess of the net proceeds received by
the Holder from the sale of such Restricted Shares over all amounts already
contributed by such Holder with respect to such claims, including amounts paid
for any legal or other fees or expenses incurred by such Holder.

          The relative fault of the Company on the one hand and of the 
Indemnified Holder on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Indemnified Holder and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a party as a result of
the losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in this paragraph (b),
any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending an action or claim.

          The Company and each Holder shall agree that it would not be just and
equitable if contribution pursuant to this paragraph (b) were determined by pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding
paragraph.  Notwithstanding the provisions of this paragraph (b), an Indemnified
Holder shall not be required to contribute any amount in excess of the amount by
which the total price at which the Restricted Shares sold by such Indemnified
Holder or its affiliated Indemnified Holders and distributed to the public were
offered to the public exceeds the amount of any damages that such Indemnified
Holder, or its affiliated Indemnified Holder, has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent 

                                      -19-

misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

          (v)    Other Indemnification.  Indemnification and contribution 
                 ---------------------                                    
similar to that specified in the preceding clauses of this paragraph (b) (with
appropriate modifications) shall be given by the Company and each seller of
Restricted Shares with respect to any required registration or other
qualification of such Restricted Shares under any Federal or state law or
regulations of governmental authority other than the Securities Act. The
indemnification and contribution rights under this paragraph (b) shall be in
addition to any rights that any indemnified person may have at common law or
otherwise.

                                 MISCELLANEOUS

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 and are hereby 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 therefor.

Section 9.02     Payment of Taxes

          The Company will pay all taxes and other governmental charges that 
may be imposed on the Company or on the holders of the Warrants or on the
holders of any securities deliverable upon exercise of Warrants with respect
thereto. The Company will not be required, however, to pay any tax or other
charge imposed in connection with any transfer involved in the issue of any
certificate for shares of Common Stock or other securities underlying the
Warrants or payment of cash or other property to any person other than the
Holder of a Warrant Certificate surrendered upon the exercise thereof, and in
case of such transfer or payment, the Warrant Agent and the Company shall not be
required to issue any stock certificate or security or pay any cash or
distribute any property until such tax or charge has been paid or it has been
established to the Warrant Agent's and the Company's satisfaction that no such
tax or other charge is due.

Section 9.03     Surrender of Certificates

          Any Warrant Certificate surrendered for exercise or purchased or 
otherwise acquired by the Company shall, if surrendered to the Company, be
delivered to the Warrant Agent, and all Warrant Certificates surrendered or so
delivered to the Warrant Agent shall promptly be canceled by such Warrant Agent
and shall not be reissued by the Company. The Warrant Agent shall return such
canceled Warrant Certificates to the Company.

Section 9.04     Mutilated, Destroyed, Lost and Stolen Warrant Certificates

          If (a) any mutilated Warrant Certificate is surrendered to the Warrant
Agent or (b) the Company and the Warrant Agent receive evidence to their
satisfaction of the destruction, loss or theft of any Warrant Certificate, and
there is delivered to the Company and the Warrant Agent such security or
indemnity as may be reasonably required by them to save each of them harmless,
then, in the absence of notice to the Company or any officer in the corporate
trust department of the Warrant Agent that such Warrant Certificate has been
acquired by a bona fide purchaser, the Company shall execute and upon its
written request the Warrant Agent shall countersign and deliver, in exchange 

                                      -20-
<PAGE>
 
for any such mutilated Warrant Certificate or in lieu of any such destroyed,
lost or stolen Warrant Certificate, a new Warrant Certificate of like tenor and
for a like aggregate number of warrants.

          Upon the issuance of any new Warrant Certificate under this Section 
9.04, the Company may require the payment by the Holder of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and other expenses (including the reasonable fees and expenses of the
Warrant Agent) in connection therewith.

          Every new Warrant Certificate executed and delivered pursuant to this
Section 9.04 in lieu of any destroyed, lost or stolen Warrant Certificate shall
constitute an original contractual obligation of the Company, whether or not the
destroyed, lost or stolen Warrant Certificate shall be at any time enforceable
by anyone, and shall be entitled to the benefits of this Agreement equally and
proportionately with any and all other Warrant Certificates duly executed and
delivered hereunder.

          The provisions of this Section 9.04 are exclusive and shall preclude 
(to the extent lawful) all other rights or remedies with respect to the
replacement of mutilated, destroyed, lost or stolen Warrant Certificates.

Section 9.05     Miscellaneous Rights

          The rights of Holders upon the occurrence of the events set forth in 
this Agreement are cumulative. If more than one such event shall occur and the
periods following the occurrence of such events and prior to the closing of the
transactions that are the subject of such events overlap, each Holder may
exercise such rights arising therefrom as such Holder may elect without any
condition imposed upon such exercise not contained in this Agreement.

          Neither the Company nor any of its Affiliates involved in any proposed
transaction that is the subject of such an event shall have any obligation to
the Holders to consummate any such proposed transaction once an agreement or
agreement in principle or decision to proceed with respect thereto is reached,
whether on the terms first proposed or as revised, or to include any Holder in,
or apprise any Holder of, any negotiations or discussions concerning any such
proposed transaction among the prospective parties thereto.

Section 9.06     Notices

          Any notice or communication by the Company or the Warrant Agent to the
other is duly given if in writing and delivered in person, mailed by first-class

receives it.

          If the Company mails a notice or communication to Holders, it shall

herein which may be defective or inconsistent with any other provision herein,
(b) to add to the covenants and agreements of the Company for the benefit of the

                      WARRANTS TO ACQUIRE COMMON STOCK OF
                        ICF KAISER INTERNATIONAL, INC.

          This certifies that _________________________________, or registered
assigns, is the registered holder of the number of Warrants set forth above (the
"Warrants").  Each Warrant entitles the holder thereof (the "Holder"), subject
to the provisions contained herein and in the Warrant Agreement referred to
below, to acquire from ICF Kaiser International, Inc., a Delaware corporation
(the "Company"), one share of Common Stock, $0.01 par value per share, of the
Company (the "Common Stock") for consideration equal to the Purchase Price (as
defined in the Warrant Agreement) per share of Common Stock.  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, 1999 (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 December 23, 1996 (the "Warrant Agreement"),
between the Company and The Bank of New York, as warrant agent (the "Warrant
Agent", which term includes any successor Warrant Agent under the Warrant
Agreement), and 


<PAGE>
 
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 hereof. The Warrant Agreement is hereby incorporated
herein by reference and made a part hereof. 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. Capitalized terms not defined herein have the meanings ascribed
thereto in the Warrant Agreement. A copy of the Warrant Agreement may be
obtained for inspection by the Holder hereof upon written request to the Company
at 9300 Lee Highway, Fairfax, Virginia 22031-1207, Attention of Senior Vice
President, General Counsel and Secretary.

          As provided in the Warrant Agreement and subject to the terms and
conditions therein set forth, the Warrants are immediately exercisable.

          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 thereof to the Holders promptly after an agreement is reached but
in no event less than 30 days prior to the closing thereof.  In the event the
Company enters into a Non-Surviving Combination, upon payment of the Purchase
Price prior to the Expiration Date, the Holder hereof 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 therefor).

          In order to exercise a Warrant, the registered Holder hereof must
surrender this Warrant Certificate at the office of the Warrant Agent, with the
Exercise Subscription Form on the reverse hereof duly executed by the Holder
hereof, with signature guaranteed as therein specified and tender the Purchase
Price therefor.

                        ------------------------------

          This Warrant Certificate and all rights hereunder are transferable by
the registered Holder hereof, 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 hereof or his attorney duly authorized in writing, with
signature guaranteed as specified in the attached Form of Assignment.  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 therewith.

          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 hereof for any purpose and as the person entitled to exercise the
rights represented hereby, or to the transfer hereof 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 hereof 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.

          This Warrant Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by an authorized signatory of the
Warrant Agent.

          This Warrant Certificate and all rights hereunder shall be governed by
and construed in accordance with the laws of the State of New York, without
regard to principles of conflicts of laws.

Ladies and Gentlemen:

          In connection with our proposed purchase of Warrants, we confirm that:

1.     We have received such information as we deem necessary in order to make
our investment decision.

2.     We understand that any subsequent transfer of the Warrants is subject to
certain restrictions and conditions set forth in the Warrant Agreement and the
undersigned agrees to be bound by, and not to resell, pledge or otherwise
transfer the Warrants except in compliance with, such restrictions and
conditions and the Securities Act of 1933, as amended (the "Securities Act").

3.     We understand that the offer and sale of the Warrants have not been
registered under the Securities Act, and that the Warrants may not be offered or
sold within the United States or to, or for the account or benefit of, U.S.
persons except as permitted in the following sentence.  We agree, on our own
behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell any Warrants, we will do so only (A) to the
Company or any subsidiary thereof, (B) inside the United States in accordance
with Rule 144A under the Securities Act to a "qualified institutional buyer" (as
defined therein), (C) inside the United States to an institutional "accredited
investor" (as defined below) that, prior to such transfer, furnishes (or has
furnished on its behalf by a U.S. broker-dealer) to the Warrant Agent a signed
letter substantially in the form hereof, (D) outside the United States in
accordance with Regulation S under the Securities Act, (E) pursuant to the
exemption from registration provided by Rule 144 under the Securities Act (if
available) or (F) pursuant to an effective registration statement under the
Securities Act, and we further agree to provide to any person purchasing
Warrants from us a notice advising such purchaser that resales of the Warrants
are restricted as stated herein.

4.     We understand that, on any proposed resale of Warrants, we will be
required to furnish to the Warrant Agent and the Company, such certification,
legal opinions and other information as the Warrant Agent and the Company may
reasonably require to confirm that the proposed sale complies with the foregoing
restrictions. We further understand that the Warrants purchased by us will bear
a legend to the foregoing effect.

5.     We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the Warrants, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or their investment, as the case may be.

6.     We are acquiring the Warrants purchased by us for our account or for one
or more accounts (each of which is an institutional "accredited investor") as to
each of which we exercise sole investment discretion.

       You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceeding or official inquiry with respect
to the matters covered hereby.

                      WARRANTS TO ACQUIRE COMMON STOCK OF
                        ICF KAISER INTERNATIONAL, INC.

     This certifies that CEDE & CO., or registered assigns, is the registered
holder of the number of Warrants set forth above (the "Warrants").  Each Warrant
entitles the holder thereof (the "Holder"), subject to the provisions contained
herein and in the Warrant Agreement referred to below, to acquire from ICF
Kaiser International, Inc., a Delaware corporation (the "Company"), one share of
Common Stock, $0.01 par value per share, of the Company (the "Common Stock") for
consideration equal to the Purchase Price (as defined in the Warrant Agreement)
per share of Common Stock.  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, 1999 (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 December 23, 1996 (the "Warrant Agreement"), between the
Company and The Bank of New York, 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 hereof.  The Warrant Agreement is hereby incorporated herein by
reference and made a part hereof.  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.  Capitalized terms not defined herein have the meanings ascribed
thereto in the Warrant Agreement.  A copy of the Warrant Agreement may be
obtained for inspection by the Holder hereof upon written request to the Company
at 9300 Lee Highway, Fairfax, Virginia 22031-1207, Attention of Senior Vice
President, General Counsel and Secretary.

     As provided in the Warrant Agreement and subject to the terms and
conditions therein set forth, the Warrants are immediately exercisable.

     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 thereof to the Holders promptly after an agreement is reached but
in no event less than 30 days prior to the closing thereof.  In the event the
Company enters into a Non-Surviving Combination, upon payment of the Purchase
Price prior to the Expiration Date, the Holder hereof 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 therefor).

2.      Exchange Offer

        (a) The Company shall file with the SEC no later than the Filing Date
an offer to exchange (the "Exchange Offer") any and all of the Registrable Notes
(other than the Private Exchange Notes, if any) for a like aggregate principal
amount of debt securities of the Company that are identical in all material
respects to the Notes (the "Exchange Notes") (and that are entitled to the
benefits of the Indenture or a trust indenture that is identical in all material
respects to the Indenture (other than such changes to the Indenture or any such
identical trust indenture as are necessary to comply with any requirements of
the SEC to effect or maintain the qualification thereof under the TIA) and that,
in either case, has been qualified under the TIA), except that the Exchange
Notes (other than Private Exchange Notes, if any) shall have been registered
pursuant to an effective Registration Statement under the Securities Act and
shall contain no restrictive legend thereon.  The Exchange Offer shall be
registered under the Securities Act on the appropriate form (the "Exchange
Registration Statement") and shall comply with all applicable tender offer rules
and regulations under the Exchange Act.  The Company agrees to use its best
efforts to (x) cause the Exchange Registration Statement to be declared
effective under the Securities Act on or before the Effectiveness Date; (y) keep
the Exchange Offer open for at least 20 business days (or longer if required by
applicable law) after the date that notice of the Exchange Offer is mailed to
Holders; and (z) consummate the Exchange Offer on or prior to the 180th day
following the Issue Date.  If after such Exchange Registration Statement is
declared effective by the SEC, the Exchange Offer or the issuance of the
Exchange Notes thereunder is interfered with by any stop order, injunction or
other order or requirement of the SEC or any other governmental agency or court,
such Exchange Registration Statement shall be deemed not to have become
effective for purposes of this Agreement.  Each Holder who participates in the
Exchange Offer will be required to represent that any Exchange Notes received by
it will be acquired in the ordinary course of its business, that at the time of
the consummation of  the Exchange Offer such Holder will have no arrangement or
understanding with any Person to participate in the distribution of the Exchange
Notes in violation of the provisions of the Securities Act and that such Holder
is not an affiliate of the Company within the meaning of the Securities Act and
is not acting on behalf of any persons or entities who could not truthfully make
the foregoing representations.  Upon consummation of the Exchange Offer in
accordance with this Section 2, the provisions of this Agreement shall continue
to apply, mutatis mutandis, solely with respect to Registrable Notes that are
Private Exchange Notes and Exchange Notes held by Participating Broker-Dealers,
and the Company shall have no further obligation to register Registrable Notes
(other than Private Exchange Notes and other than in respect of any Exchange
Notes as to which clause 2(c)(v) hereof applies) pursuant to Section 3 hereof.
No securities other than the Exchange Notes shall be included in the Exchange
Registration Statement.

        (b) The Company shall include within the Prospectus contained in the
Exchange Registration Statement a section entitled "Plan of Distribution,"
reasonably acceptable to the Initial Purchaser, that shall contain a summary
statement of the positions taken or policies made by the Staff of the SEC with
respect to the potential "underwriter" status of any broker-dealer that is the
beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange
Notes received by such broker-dealer in the Exchange Offer (a "Participating
Broker-Dealer"), whether such positions or policies have been publicly
disseminated by the staff of the SEC or such positions or policies, in the
judgment of the Initial Purchaser, represent the prevailing views of the Staff
of the SEC.  Such "Plan of Distribution" section shall also expressly permit the
use of the Prospectus by all Persons subject to the prospectus delivery
requirements of the Securities Act, including all Participating Broker-Dealers,
and include a statement describing the means by which Participating Broker-
Dealers may resell the Exchange Notes.

        The Company shall use its best efforts to keep the Exchange Registration
Statement effective and to amend and supplement the Prospectus contained therein
in order to permit such Prospectus to be lawfully delivered by all Persons
subject to the prospectus delivery requirements of the Securities Act for such
period of time as is necessary to comply with applicable law in connection with
any resale of the Exchange Notes; provided, however, that such period shall not
exceed 180 days after the consummation of the Exchange Offer (or such longer
period if extended pursuant to the last paragraph of Section 5 hereof) (the
"Applicable Period").

                                       3
<PAGE>
 
        If, prior to consummation of the Exchange Offer, the Initial Purchaser
holds any Notes acquired by it and having, or that are reasonably likely to be
determined to have, the status of an unsold allotment in the initial
distribution, the Company, upon the request of the Initial Purchaser
simultaneously with the delivery of the Exchange Notes in the Exchange Offer,
shall issue and deliver to the Initial Purchaser in exchange (the "Private
Exchange") for such Notes held by the Initial Purchaser a like principal amount
of debt securities of the Company that are identical in all material respects to
the Exchange Notes (the "Private Exchange Notes") (and that are issued pursuant
to the same indenture as the Exchange Notes), except for the placement of a
restrictive legend on such Private Exchange Notes.  The Private Exchange Notes
shall bear the same CUSIP number as the Exchange Notes.

        Interest on the Exchange Notes and the Private Exchange Notes will
accrue from the last interest payment date on which interest was paid on the
Notes surrendered in exchange therefor or, if no interest has been paid on the
Notes, from the Issue Date.

        In connection with the Exchange Offer, the Company shall:

        (1) mail to each Holder a copy of the Prospectus forming part of the
Exchange Registration Statement, together with an appropriate letter of
transmittal and related documents;

        (2) utilize the services of a depositary for the Exchange Offer with
an address in the Borough of Manhattan, The City of New York;

        (3) permit Holders to withdraw tendered Notes at any time prior to the
close of business, New York time, on the last business day on which the Exchange
Offer shall remain open; and

        (4) otherwise comply in all material respects with all applicable laws,
rules and regulations.

        As soon as practicable after the close of the Exchange Offer or the
Private Exchange, as the case may be, the Company shall:

        (1) accept for exchange all Notes properly tendered and not validly
withdrawn pursuant to the Exchange Offer or the Private Exchange;

        (2) deliver to the Trustee for cancellation all Notes so accepted for
exchange; and

        (3) cause the Trustee to authenticate and deliver promptly to each
Holder of Notes, Exchange Notes or Private Exchange Notes, as the case may be,
equal in principal amount to the Notes of such Holder so accepted for exchange.

        The Exchange Notes and the Private Exchange Notes may be issued under
(i) the Indenture or (ii) an indenture identical in all material respects to the
Indenture, which in either event shall provide that (1) the Exchange Notes shall
not be subject to the transfer restrictions set forth in the Indenture and (2)
the Private Exchange Notes shall be subject to the transfer restrictions set
forth in the Indenture. The Indenture or such indenture shall provide that the
Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent
together on all matters as one class and that neither the Exchange Notes, the
Private Exchange Notes or the Notes will have the right to vote or consent as a
separate class on any matter.

        (c) If, (i) because of any change in law or in currently prevailing
interpretations of the Staff of the SEC, the Company is not permitted to effect
an Exchange Offer, (ii) the Exchange Offer is not consummated within 180 days of
the Issue Date, (iii) the holder of Private Exchange Notes so requests at any
time after the consummation of the Private Exchange, (iv) the Holders of not
less than a majority in aggregate principal amount of the Registrable Notes
determine that the interests of the Holders would be materially adversely
affected by consummation of the Exchange Offer or (v) in the case of any Holder
that participates in the Exchange Offer, such Holder does not receive Exchange
Notes on the date of the exchange that may be sold without restriction under
state 

                                       4
<PAGE>
 
and federal securities laws (other than due solely to the status of such
Holder as an affiliate of the Company within the meaning of the Securities Act),
then the Company shall promptly deliver  to the Holders and the Trustee written
notice thereof (the "Shelf Notice") to the Trustee and in the case of clauses
(i), (ii) and (iv), all Holders, in the case of clause (iii), the Holders of the
Private Exchange Notes and in the case of clause (v), the affected Holder, and
shall file a Shelf Registration pursuant to Section 3 hereof.

3.      Shelf Registration

        If a Shelf Notice is delivered as contemplated by Section 2(c) hereof,
then:

        (a) Shelf Registration.  The Company shall as promptly as reasonably
practicable file with the SEC a Registration Statement for an offering to be
made on a continuous basis pursuant to Rule 415 covering all of the Registrable
Notes (the "Shelf Registration").  If the Company shall not have yet filed an
Exchange Registration Statement, the Company shall use its best efforts to file
with the SEC the Shelf Registration on or prior to the Filing Date.  The Shelf
Registration shall be on Form S-1 or another appropriate form permitting
registration of such Registrable Notes for resale by Holders in the manner or
manners designated by them (including, without limitation, one or more
underwritten offerings).  The Company shall not permit any securities other than
the Registrable Notes to be included in the Shelf Registration.

        The Company shall use its best efforts to cause the Shelf Registration
to be declared effective under the Securities Act on or prior to the
Effectiveness Date and to keep the Shelf Registration continuously effective
under the Securities Act until the date that is three years from the Issue Date
(the "Effectiveness Period"), or such shorter period ending when all Registrable
Notes covered by the Shelf Registration have been sold in the manner set forth
and as contemplated in the Shelf Registration.

        (b) Withdrawal of Stop Orders.  If the Shelf Registration ceases to be
effective for any reason at any time during the Effectiveness Period (other than
because of the sale of all of the securities registered thereunder), the Company
shall use its best efforts to obtain the prompt withdrawal of any order
suspending the effectiveness thereof.

        (c) Supplements and Amendments.  The Company shall promptly supplement
and amend the Shelf Registration if required by the rules, regulations or
instructions applicable  to the registration form used for such Shelf
Registration, if required by the Securities Act, or if reasonably requested by
the Holders of a majority in aggregate principal amount of the Registrable Notes
covered by such Registration Statement or by any underwriter of such Registrable
Notes.

4.      Additional Interest

        (a) The Company and the Initial Purchaser agree that the Holders of
Registrable Notes will suffer damages if the Company fails to fulfill its
obligation under Section 2 or Section 3 hereof and that it would not be feasible
to ascertain the extent of such damages with precision.  Accordingly, the
Company agrees to pay, as liquidated damages, additional interest on the Notes
("Additional Interest") under the circumstances and to the extent set forth
below (without duplication):

            (i)   if neither the Exchange Registration Statement nor the Shelf
Registration has been filed on or prior to the Filing Date, Additional Interest
shall accrue on the Notes over and above the stated interest at a rate of 0.50%
per annum for the first 90 days immediately following the Filing Date, such
Additional Interest rate increasing by an additional 0.50% per annum at the
beginning of each subsequent 90-day period;

            (ii)  if neither the Exchange Registration Statement nor the Initial
Shelf Registration is declared effective by the SEC on or prior to the
Effectiveness Date, then, commencing on the 136th day after the Issue Date,
Additional Interest shall be accrued on the Notes included or that should have
been included in such Registration Statement over and above the stated interest
at a rate of 0.50% per annum for the first 90 days 

                                       5
<PAGE>
 
immediately following the Effectiveness Date, such Additional Interest rate
increasing by an additional 0.50% per annum at the beginning of each subsequent
90-day period; and

            (iii) if either (A) the Company has not exchanged Exchange Notes for
all Notes validly tendered in accordance with the terms of the Exchange Offer on
or prior to the 180th day after the Issue Date or (B) the Exchange Registration
Statement ceases to be effective at any time prior to the time that the Exchange
Offer is consummated or (C) if applicable, the Shelf Registration has been
declared effective and such Shelf Registration  ceases to be effective at any
time during the Effectiveness Period, then Additional Interest shall be accrued
on the Notes (over and above any interest otherwise payable on the Notes) at a
rate of 0.50% per annum on (x) the 181st day after the Issue Date, in the case
of (A) above, or (y) the day the Exchange Registration Statement ceases to be
effective without being declared effective within five business days in the case
of (B) above, or (z) the day such Shelf Registration ceases to be effective, in
the case of (C) above, such Additional Interest rate increasing by an additional
0.50% per annum at the beginning of each such subsequent 90-day period (it being
understood and agreed that, notwithstanding any provision to the contrary, so
long as any Note that is the subject of a Shelf Notice is then covered by an
effective Shelf Registration Statement, no Additional Interest shall accrue on
such Note);

provided, however, that the Additional Interest rate on any affected Note may
not exceed at any one time in the aggregate 2.0% per annum; and provided,
further, that (1) upon the filing of the Exchange Registration Statement or a
Shelf Registration (in the case of clause (i) of this Section 4(a)), (2) upon
the effectiveness of the Exchange Registration Statement or the Shelf
Registration (in the case of clause (ii) of this Section 4(a)), or (3) upon the
exchange of Exchange Notes for all Notes tendered (in the case of clause
(iii)(A) of this Section 4(a)), or upon the effectiveness of the Exchange
Registration Statement that had ceased to remain effective (in the case of
(iii)(B) of this Section 4(a)) or upon the effectiveness of the Shelf
Registration that had ceased to remain effective (in the case of (iii)(C) of
this Section 4(a)), Additional Interest on the affected Notes as a result of
such clause (or the relevant subclause thereof), as the case may be, shall cease
to accrue.

        (b) The Company shall notify the Trustee within one business day after
each and every date on which an event occurs in respect of which Additional
Interest is required to be paid (an "Event Date").  Any amounts of Additional
Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be
payable in cash semi-annually on each December 31 and June 30 (to the holders of
record on the December 15 and June 15 immediately preceding such dates),
commencing with the first such date occurring after any such Additional Interest
commences to accrue.  The amount of Additional Interest will be determined by
multiplying the applicable Additional Interest rate by the principal amount of
the Registrable Notes, multiplied by a fraction, the numerator of which is the
number of days such Additional Interest rate was applicable during such period
(determined on the basis of a 360-day year consisting of twelve 30-day months
and, in the case of a partial month, the actual number of days elapsed) and the
denominator of which is 360.

5.      Registration Procedures

        In connection with the filing of any Registration Statement pursuant to
Sections 2 or 3 hereof, the Company shall effect such registrations to permit
the sale of the securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Company, hereunder the Company
shall:

        (a) Prepare and file with the SEC prior to the Filing Date, a
Registration Statement or Registration Statements as prescribed by Sections 2 or
3 hereof, and use its best efforts to cause each such Registration Statement to
become effective and remain effective as provided herein; provided, however,
that, if (1) such filing is pursuant to Section 3 hereof or (2) a Prospectus
contained in an Exchange Registration Statement filed pursuant to Section 2
hereof is required to be delivered under the Securities Act by any Participating
Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period,
before filing any Registration Statement or Prospectus or any amendments or
supplements thereto, the Company shall furnish to and afford the Holders of the
Registrable Notes covered by such Registration Statement or each such
Participating Broker-Dealer, as the case may be, their counsel and the managing
underwriters, if any, a reasonable opportunity to review copies of all such
documents (including 

                                       6
<PAGE>
 
copies of any documents to be incorporated by reference therein and all exhibits
thereto) proposed to be filed (in each case at least five business days prior to
such filing). The Company shall not file any Registration Statement or
Prospectus or any amendments or supplements thereto if the Holders of a majority
in aggregate principal amount of the Registrable Notes covered by such
Registration Statement, or any such Participating Broker-Dealer, as the case may
be, or their counsel, or the managing underwriters, if any, shall reasonably
object.

        (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Shelf Registration or Exchange Registration Statement, as the
case may be, as may be necessary to keep such Registration Statement
continuously effective for the Effectiveness Period or the Applicable Period, as
the case may be; cause the related Prospectus to be supplemented by any
prospectus supplement required by applicable law, and as so supplemented to be
filed pursuant to Rule 424 (or any similar provisions then in force) promulgated
under the Securities Act; and comply with the provisions of the Securities Act
and the Exchange Act applicable to it with respect to the disposition of all
securities covered by such Registration Statement as so amended or in such
Prospectus as so supplemented and with respect to the subsequent resale of any
securities being sold by a Participating Broker-Dealer covered by any such
Prospectus; the Company shall be deemed not to have used its best efforts to
keep a Registration Statement effective during the Applicable Period if it
voluntarily takes any action that would result in selling Holders of the
Registrable Notes covered thereby or Participating Broker-Dealers seeking to
sell Exchange Notes not being able to sell such Registrable Notes or such
Exchange Notes during that period, unless such action is required by applicable
law or unless the Company complies with this Agreement, including without
limitation, the provisions of paragraph 5(k) hereof and the last paragraph of
this Section 5.

        (c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof
or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, notify the selling Holders of Registrable Notes, or each
such Participating Broker-Dealer, as the case may be, their counsel and the
managing underwriters, if any, promptly (but in any event within two business
days) and confirm such notice in writing, (i) when a Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective under the Securities Act (including in such notice a
written statement that any Holder may, upon request, obtain, at the sole expense
of the Company, one conformed copy of such Registration Statement or post-
effective amendment including financial statements and schedules, documents
incorporated or deemed to be incorporated by reference and exhibits), (ii) of
the issuance by the SEC of any stop order suspending the  effectiveness of a
Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus or the initiation of any proceedings for that purpose,
(iii) if at any time when a prospectus is required by the Securities Act to be
delivered in connection with sales of the Registrable Notes or resales of
Exchange Notes by Participating Broker-Dealers the representations and
warranties of the Company contained in any agreement (including any underwriting
agreement), contemplated by Section 5(n) hereof cease to be true and correct,
(iv) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of a
Registration Statement or any of the Registrable Notes or the Exchange Notes to
be sold by any Participating Broker-Dealer for offer or sale in any
jurisdiction, or the initiation or written threat of any proceeding for such
purpose, (v) of the happening of any event, the existence of any condition or
any information becoming known that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respects
or that requires the making of any changes in or amendments or supplements to
such Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading and (vi) of the Company's determination that a post-
effective amendment to a Registration Statement would be appropriate.

        (d) Use its reasonable best efforts to prevent the issuance of any
order suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of a Prospectus or suspending the 

                                       7
<PAGE>
 
qualification (or exemption from qualification) of any of the Registrable Notes
or the Exchange Notes for sale in any jurisdiction and, if any such order is
issued, to use their best efforts to obtain the withdrawal of any such order at
the earliest possible moment.

        (e) If a Shelf Registration is filed pursuant to Section 3 and if
requested by the managing underwriter or underwriters, if any, or the Holders of
a majority in aggregate principal amount of the Registrable Notes being sold in
connection with an underwritten offering, (i) promptly incorporate in a
prospectus supplement or post-effective amendment such information as the
managing underwriter or underwriters, if any, such Holders or counsel for any of
them determine is reasonably necessary to be included therein, (ii) make all
required filings of such prospectus supplement or such post-effective amendment
as soon as practicable after the Company has received notification of the
matters to be incorporated in such prospectus supplement or post-effective
amendment and (iii) supplement or make amendments to such Registration
Statement.

        (f) If (1) a Shelf Registration is filed pursuant to Section 3 hereof
or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, furnish to each selling Holder of Registrable Notes and
to each such Participating Broker-Dealer who so requests and to their respective
counsel and each managing underwriter, if any, at the sole expense of the
Company, one conformed copy of the Registration Statement or Registration
Statements and each post-effective amendment thereto, including financial
statements and schedules and, if requested, all documents incorporated or deemed
to be incorporated therein by reference and all exhibits.

        (g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof
or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, deliver to each selling Holder of Registrable Notes, or
each such Participating Broker-Dealer, as the case may be, their respective
counsel and the underwriters, if any, at the sole expense of the Company, as
many copies of the Prospectus or Prospectuses (including each form of
preliminary prospectus) and each amendment or supplement thereto and any
documents incorporated by reference therein as such Persons may reasonably
request; and, subject to the last paragraph of this Section 5, the Company
hereby consents to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders of Registrable Notes or each such
Participating Broker-Dealer, as the case may be, and the underwriters or agents,
if any, and dealers, if any, in connection with the offering and sale of the
Registrable Notes  covered by, or the sale by Participating Broker-Dealers of
the Exchange Notes pursuant to, such Prospectus and any amendment or supplement
thereto.

        (h) Prior to any public offering of Registrable Notes or Exchange
Notes or any delivery of a Prospectus contained in the Exchange Registration
Statement by any Participating Broker-Dealer who seeks to sell Exchange Notes
during the Applicable Period, to use their best efforts to register or qualify
and to cooperate with the selling Holders of Registrable Notes or each such
Participating Broker-Dealer, as the case may be, the managing underwriter or
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Notes for offer and sale under the securities
or Blue Sky laws of such jurisdictions within the United States as any selling
Holder, Participating Broker-Dealer or the managing underwriter or underwriters
reasonably request in writing; provided, however, that where Exchange Notes held
by Participating Broker-Dealers or Registrable Notes are offered other than
through an underwritten offering, the Company agrees to cause the Company's
counsel to perform Blue Sky investigations and file registrations and
qualifications required to be filed pursuant to this Section 5(h); keep each
such registration or qualification (or exemption therefrom) effective during the
period such Registration Statement is required to be kept effective and do any
and all other acts or things reasonably necessary or advisable to enable the
disposition in such jurisdictions of the Exchange Notes held by Participating
Broker-Dealers or the Registrable Notes covered by the applicable Registration
Statement; provided, however, that the Company shall not be required to (A)
qualify generally to do business in any jurisdiction where it is not then so
qualified, (B) take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject or (C) subject
itself to taxation in any such jurisdiction where it is not then so subject.

                                       8

        (i) If a Shelf Registration is filed pursuant to Section 3 hereof,
cooperate with the selling Holders of Registrable Notes and the managing
underwriter or underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Notes to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depository Trust Company; and enable such
Registrable Notes to be in such  denominations and registered in such names as
the managing underwriter or underwriters, if any, or Holders may reasonably
request.

        (j) Use its best efforts to cause the Registrable Notes covered by the
Registration Statement to be registered with or approved by such other
governmental agencies or authorities as may be necessary to enable the Holders
thereof or the underwriter or underwriters, if any, to consummate the
disposition of such Registrable Notes, except as may be required solely as a
consequence of the nature of such selling Holder's business, in which case the
Company will cooperate in all reasonable respects with the filing of such
Registration Statement and the granting of such approvals.

        (k) If (1) a Shelf Registration is filed pursuant to Section 3 hereof
or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, upon the occurrence of any event contemplated by
paragraph 5(c)(v) or 5(c)(vi), hereof, as promptly as practicable prepare and
(subject to Section 5(a) hereof) file with the SEC, at the Company's sole
expense, a supplement or post-effective amendment to the Registration Statement
or a supplement to the related Prospectus or any document incorporated or deemed
to be incorporated therein by reference, or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable Notes being
sold thereunder or to the purchasers of the Exchange Notes to whom such
Prospectus will be delivered by a Participating Broker-Dealer, any such
Prospectus will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

        (l) Use its best efforts to cause the Registrable Notes covered by a
Registration Statement or the Exchange Notes, as the case may be, to be rated
with the appropriate rating agencies, if so requested by the Holders of a
majority in aggregate principal amount of Registrable Notes covered by such
Registration Statement or the Exchange Notes, as the case may be, or the
managing underwriter or underwriters, if any.

        (m) Prior to the effective date of the first Registration Statement
relating to the Registrable Notes, (i) provide the Trustee with certificates
for the Registrable Notes or Exchange Notes, as the case may be, in a form
eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP
number for the Registrable Notes or Exchange Notes, as the case may be.

        (n) In connection with any underwritten offering of Registrable Notes
pursuant to a Shelf Registration, enter into an underwriting agreement as is
customary in underwritten offerings of debt securities similar to the Notes and
take all such other actions as are reasonably requested by the managing
underwriter or underwriters in order to expedite or facilitate the registration
or the disposition of such Registrable Notes and, in such connection, (i) make
such representations and warranties to, and covenants with, the underwriters
with respect to the business of the Company and its subsidiaries (including any
acquired business, properties or entity, if applicable) and the Registration
Statement, Prospectus and documents, if any, incorporated or deemed to be
incorporated by reference therein, in each case, as are customarily made by
issuers to underwriters in underwritten offerings of debt securities similar to
the Notes, and confirm the same in writing if and when requested; (ii) obtain
the written opinion of counsel to the Company and written updates thereof in
form, scope and substance reasonably satisfactory to the managing underwriter or
underwriters, addressed to the underwriters covering the matters customarily
covered in opinions requested in underwritten offerings of debt similar to the
Notes and such other matters as may be reasonably requested by the managing
underwriter or underwriters; (iii) obtain "cold comfort" letters and updates
thereof in form, scope and substance reasonably satisfactory to the managing
underwriter or underwriters from the independent certified public accountants of
the Company (and, if necessary, any other independent certified public
accountants of any subsidiary of the Company or of any business acquired by the

                                       9
<PAGE>
 
Company for which financial statements and financial data are, or are required
to be, included or incorporated by reference in the Registration Statement),

covering matters of the type customarily covered in "cold comfort" letters in
connection with underwritten offerings of debt securities similar to the Notes
and such other matters as reasonably requested by the managing underwriter or
underwriters; and (iv) if an underwriting agreement is entered into, the same
shall contain indemnification provisions and procedures no less favorable than
those set forth in Section 7 hereof (or such other  provisions and procedures
acceptable to Holders of a majority in aggregate principal amount of Registrable
Notes covered by such Registration Statement and the managing underwriter or
underwriters or agents) with respect to all parties to be indemnified pursuant
to said Section.  The above shall be done at each closing under such
underwriting agreement, or as and to the extent required thereunder.

        (o) If (1) a Shelf Registration is filed pursuant to Section 3 hereof
or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 hereof is required to be delivered under the Securities
Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during
the Applicable Period, make available for inspection by any selling Holder of
such Registrable Notes being sold, or each such Participating Broker-Dealer, as
the case may be, any underwriter participating in any such disposition of
Registrable Notes, if any, and any attorney, accountant or other agent retained
by any such selling Holder or each such Participating Broker-Dealer, as the case
may be, or underwriter (collectively, the "Inspectors"), at the offices where
normally kept, during reasonable business hours, all financial and other
records, pertinent corporate documents and instruments of the Company and its
subsidiaries (collectively, the "Records") as shall be reasonably necessary to
enable them to exercise any applicable due diligence responsibilities, and cause
the respective officers, directors and employees of the Company and its
subsidiaries to supply all information reasonably requested by any such
Inspector in connection with such Registration Statement.  Records that the
Company determines, in good faith, to be confidential and any Records that it
notifies the Inspectors are confidential shall not be disclosed by the
Inspectors unless (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in such Registration Statement, (ii) the
release of such Records is ordered pursuant to a subpoena or other order from a
court of competent jurisdiction, (iii) disclosure of such information is, in the
opinion of counsel for any Inspector, necessary or advisable in connection with
any action, claim, suit or proceeding, directly or indirectly, involving or
potentially involving such Inspector and arising out of, based upon, relating to
or involving this Agreement or any transactions contemplated hereby or arising
hereunder or (iv) the information in such Records has been made generally
available to the public.  Each selling Holder of such Registrable Securities and
each such Participating Broker-Dealer will be required to agree that information
obtained by it as a result  of such inspections shall be deemed confidential and
shall not be used by it as the basis for any market transactions in the
securities of the Company unless and until such information is generally
available to the public.  Each selling Holder of such Registrable Notes and each
such Participating Broker-Dealer will be required to further agree that it will,
upon learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Company and allow the Company to undertake
appropriate action to prevent disclosure of the Records deemed confidential at
the Company's sole expense.

        (p) Provide an indenture trustee for the Registrable Notes or the
Exchange Notes, as the case may be, and cause the Indenture or the trust
indenture provided for in Section 2(a) hereof, as the case may be, to be
qualified under the TIA not later than the effective date of the Exchange Offer
or the first Registration Statement relating to the Registrable Notes; and in
connection therewith, cooperate with the trustee under any such indenture and
the Holders of the Registrable Notes, to effect such changes to such indenture
as may be required for such indenture to be so qualified in accordance with the
terms of the TIA; and execute, and use its reasonable best efforts to cause such
trustee to execute, all documents as may be required to effect such changes and
all other forms and documents required to be filed with the SEC to enable such
indenture to be so qualified in a timely manner.

        (q) Comply with all applicable rules and regulations of the SEC and
make generally available to its securityholders earning statements satisfying
the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder
(or any similar rule promulgated under the Securities Act) no later than 45 days
after the end of any 12-month period (or 90 days after the end of any 12-month
period if such period is a fiscal year) (i) commencing at the end of any fiscal
quarter in which Registrable Notes are sold to underwriters in a firm commitment
or best efforts 

                                       10
<PAGE>
 
underwritten offering and (ii) if not sold to underwriters in such an offering,
commencing on the first day of the first fiscal quarter of the Company after the
effective date of a Registration Statement, which statements shall cover said
12-month periods.

        (r) Upon consummation of an Exchange Offer or a Private Exchange,
obtain an opinion of counsel to the Company, who may, at the Company's election,
be internal counsel to the Company, in a form customary for underwritten
transactions,  addressed to the Trustee for the benefit of all Holders of
Registrable Notes participating in the Exchange Offer or the Private Exchange,
as the case may be, that the Exchange Notes or Private Exchange Notes, as the
case may be, and the related indenture constitute legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
its respective terms, subject to customary exceptions and qualifications.

        (s) If an Exchange Offer or a Private Exchange is to be consummated,
upon delivery of the Registrable Notes by Holders to the Company (or to such
other Person as directed by the Company) in exchange for the Exchange Notes or
the Private Exchange Notes, as the case may be, the Company shall mark, or cause
to be marked, on such Registrable Notes that such Registrable Notes are being
cancelled in exchange for the Exchange Notes or the Private Exchange Notes, as
the case may be; in no event shall such Registrable Notes be marked as paid or
otherwise satisfied.

        (t) Cooperate with each seller of Registrable Notes covered by any
Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Notes and their respective counsel in connection
with any filings required to be made with the National Association of Securities
Dealers, Inc. (the "NASD").

        (u) Use its best efforts to take all other steps necessary or
advisable to effect the registration of the Registrable Notes covered by a
Registration Statement contemplated hereby.

        The Company may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Company such information
regarding such seller and the distribution of such Registrable Notes as the
Company may, from time to time, reasonably request.  The Company may exclude
from such registration the Registrable Notes of any seller who unreasonably
fails to furnish such information within a reasonable time after receiving such
request and in such event shall have no further obligation under this Agreement
(including, without limitation, obligations under Section 4 hereof) with respect
to such seller or any subsequent holder of such Registrable Notes.  Each seller
as to which any Shelf Registration is being effected agrees to furnish promptly
to the Company all information required to be disclosed in order  to make the
information previously furnished to the Company by such seller not materially
misleading.

        Each Holder of Registrable Notes and each Participating Broker-Dealer
agrees by acquisition of such Registrable Notes or Exchange Notes to be sold by
such Participating Broker-Dealer, as the case may be, that, upon actual receipt
of any notice from the Company of the happening of any event of the kind
described in Sections 5(c)(ii), 5(c)(iv), 5(c)(v) or 5(c)(vi) hereof, such
Holder will forthwith discontinue disposition of such Registrable Notes covered
by such Registration Statement or Prospectus or Exchange Notes to be sold by
such Holder or Participating Broker-Dealer, as the case may be, until such
Holder's or Participating Broker-Dealer's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until
it is advised in writing (the "Advice") by the Company that the use of the
applicable Prospectus may be resumed, and has received copies of any amendments
or supplements thereto.  In the event that the Company shall give any such
notice, each of the Effectiveness Period and the Applicable Period shall be
extended by the number of days during such periods from and including the date
of the giving of such notice to and including the date when each seller of
Registrable Notes covered by such Registration Statement or Exchange Notes to be
sold by such Participating Broker-Dealer, as the case may be, shall have
received (x) the copies of the supplemented or amended Prospectus contemplated
by Section 5(k) hereof or (y) the Advice.

Act (each, a "Participant"), from and against any and all losses, claims,
damages and liabilities (including, without limitation, the reasonable legal
fees and other expenses actually incurred in connection with any suit, action or
proceeding or any claim asserted) caused by, arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement pursuant to which the offering of such Registrable Notes
or Exchange Notes, as the case may be, is registered (or any amendment thereto)
or related Prospectus (or any amendments or supplements thereto) or any related
preliminary prospectus, or caused by, arising out of or based upon any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not 

                                       12

misleading; provided, however, that the Company will not be required to
indemnify a Participant if (i) such losses, claims, damages or liabilities are
caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to
any Participant furnished to the Company in writing by or on behalf of such
Participant expressly for use therein or (ii) if such Participant sold to the
person asserting the claim the Registrable Notes or Exchange Notes that are the
subject of such claim and such untrue statement or omission or alleged untrue
statement or omission was contained or made in any preliminary prospectus and
corrected in the Prospectus or any amendment or supplement thereto and the
Prospectus does not contain any other untrue statement or omission or alleged
untrue statement or omission of a material fact that was the subject matter of
the related proceeding and it is established by the Company in the related
proceeding that such Participant failed to deliver or provide a copy of the
Prospectus (as amended or supplemented) to such Person with or prior to the
confirmation of the sale of such Registrable Notes or Exchange Notes sold to
such Person if required by applicable law, unless such failure to deliver or
provide a copy of the Prospectus (as amended or supplemented) was a result of
noncompliance by the Company with Section 5 of this Agreement.

        (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors and officers and each Person who
controls the Company within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company to each Participant, but only (i) with reference to information
relating to such Participant furnished to the Company in writing by or on behalf
of such Participant expressly for use in any Registration Statement or
Prospectus, any amendment or supplement thereto or any preliminary prospectus or
(ii) with respect to any untrue statement or representation made by such
Participant in writing to the Company.  The liability of any Participant under
this paragraph shall in no event exceed the proceeds received by such
Participant from sales of Registrable Notes or Exchange Notes giving rise to
such obligations.

        (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnity may be sought pursuant to either of the
two preceding paragraphs, such Person (the "Indemnified Person") shall promptly
notify the Person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and expenses actually incurred by such counsel related to
such proceeding; provided, however, that the failure to so notify the
Indemnifying Person shall not relieve it of any obligation or liability that it
may have hereunder or otherwise (unless and only to the extent that such failure
directly results in the loss or compromise of any material rights or defenses by
the Indemnifying Person and the Indemnifying Person was not otherwise aware of
such action or claim).  In any such proceeding, any Indemnified Person shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed in
writing to the contrary, (ii) the Indemnifying Person shall have failed within a
reasonable period of time to retain counsel reasonably satisfactory to the
Indemnified Person or (iii) the named parties in any such proceeding (including
any impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them.  It
is understood that, unless there exists a conflict among Indemnified Persons,
the Indemnifying Person shall not, in connection with any one such proceeding or
separate but substantially similar related proceeding in the same jurisdiction
arising out of the same general allegations, be liable for the fees and expenses
of more than one separate firm (in addition to any local counsel) for all
Indemnified Persons, and that all such fees and expenses shall be reimbursed
promptly as they are incurred.  Any such separate firm for the Participants and
such control Persons of Participants shall be designated in writing by
Participants who sold a majority in interest of Registrable Notes and Exchange
Notes sold by all such Participants and any such separate firm for the Company,
its directors, its officers and such control Persons of the Company shall be
designated in writing by the Company.  The Indemnifying Person shall not be
liable for any settlement of any proceeding effected without its prior written
consent, but if settled with such consent or if there be a final non-appealable
judgment for the plaintiff for which the Indemnified Person is entitled to
indemnification pursuant to this Agreement, the Indemnifying Person agrees to
indemnify and hold harmless each Indemnified Person from and against any loss or

                                       13
<PAGE>
 
liability by reason of such settlement or judgment.  Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested an
Indemnifying Person to reimburse the Indemnified Person for reasonable fees and
expenses actually incurred by counsel as contemplated by the third sentence of
this paragraph, the Indemnifying Person agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 30 days after receipt by such Indemnifying
Person of the aforesaid request and (ii) such Indemnifying Person shall not have
reimbursed the Indemnified Person in accordance with such request prior to the
date of such settlement; provided, however, that the Indemnifying Person shall
not be liable for any settlement effected without its consent pursuant to this
sentence if the Indemnifying Person is contesting, in good faith, the request
for  reimbursement.  No Indemnifying Person shall, without the prior written
consent of the Indemnified Person, effect any settlement or compromise of any
pending or threatened proceeding in respect of which any Indemnified Person is
or could have been a party, and indemnity could have been sought hereunder by
such Indemnified Person, unless such settlement (A) includes an unconditional
written release of such Indemnified Person, in form and substance reasonably
satisfactory to such Indemnified Person, from all liability on claims that are
the subject matter of such proceeding and (B) does not include any statement as
to an admission of fault, culpability or failure to act by or on behalf of any
Indemnified Person.

        (d) If the indemnification provided for in the first and second
paragraphs of this Section 7 is for any reason unavailable to, or insufficient
to hold harmless, an Indemnified Person in respect of any losses, claims,
damages or liabilities referred to therein, then each Indemnifying Person under
such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and
in order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
(i) the relative benefits received by the Indemnifying Person or Persons on the
one hand and the Indemnified Person or Persons on the other from the offering of
the Notes or (ii) if the allocation provided by the foregoing clause (i) is not
permitted by applicable law, not only such relative benefits but also the
relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions or alleged statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof).  The relative
fault of the parties shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or such Participant or such other
Indemnified Person, as the case may be, on the other, the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission, and any other equitable considerations appropriate
in the circumstances.

        (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were  determined by pro rata allocation
(even if the Participants were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Person as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any reasonable
legal or other expenses actually incurred by such Indemnified Person in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall a
Participant be required to contribute any amount in excess of the amount by
which proceeds received by such Participant from sales of Registrable Notes or
Exchange Notes, as the case may be, exceeds the amount of any damages that such
Participant has otherwise been required to pay or has paid by reason of such
untrue or alleged untrue statement or omission or alleged omission.  No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

        (f) The indemnity and contribution agreements contained in this
Section 7 will be in addition to any liability that the Indemnifying Persons may
otherwise have to the Indemnified Persons referred to above.

8.      Rule 144 and 144A

                                       14
<PAGE>
 
        The Company covenants that it will file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder in a timely manner in accordance with
the requirements of the Securities Act and the Exchange Act and, if at any time
the Company is not required to file such reports, it will, upon the request of
any Holder of Registrable Notes, make publicly available annual reports and such
information, documents and other reports of the type specified in Sections 13
and 15(d) of the Exchange Act.  The Company further covenants for so long as any
Registrable Notes remain outstanding, to make available to any Holder or
beneficial owner of Registrable Notes in connection with any sale thereof and
any prospective purchaser of such Registrable Notes from such Holder or
beneficial owner the information required by Rule 144A(d)(4) under the
Securities Act in order to permit resales of such Registrable Notes pursuant to
Rule 144A.

9.      Underwritten Registrations

        If any of the Registrable Notes covered by any Shelf Registration are
to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of a majority in aggregate principal amount of such Registrable
Notes included in such offering and reasonably acceptable to the Company.

        No Holder of Registrable Notes may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

10.     Miscellaneous

        (a) No Inconsistent Agreements.  The Company has not, as of the date
hereof, and shall not, after the date of this Agreement, enter into any
agreement with respect to any of the Company's securities that is inconsistent
with the rights granted to the Holders of Registrable Notes in this Agreement or
otherwise conflicts with the provisions hereof.  The Company has not entered and
will not enter into any agreement with respect to any of its securities that
will grant to any Person piggy-back registration rights with respect to a
Registration Statement.

        (b) Adjustments Affecting Registrable Notes.  The Company shall not,
directly or indirectly, take any action with respect to the Registrable Notes as
a class that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes in a registration undertaken pursuant to
this Agreement.

        (c) Amendments and Waivers.  The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, otherwise than with the prior written
consent of the Holders of not less than a majority in aggregate principal amount
of the then outstanding Registrable Notes.  Notwithstanding the foregoing, a
waiver or consent to depart  from the provisions hereof with respect to a matter
that relates exclusively to the rights of Holders of Registrable Notes whose
securities are being sold pursuant to a Registration Statement and that does not
directly or indirectly affect, impair, limit or compromise the rights of other
Holders of Registrable Notes may be given by Holders of at least a majority in
aggregate principal amount of the Registrable Notes being sold by such Holders
pursuant to such Registration Statement; provided, however, that the provisions
of this sentence may not be amended, modified or supplemented except in
accordance with the provisions of the immediately preceding sentence.

        (d) Notices.  All notices and other communications (including without
limitation any notices or other communications to the Trustee) provided for or
permitted hereunder shall be made in writing by hand-delivery, registered first-
class mail, next-day air courier or facsimile:

               12% Senior Notes due 2003, Series B
               Registration Statement on Form S-1
               -------------------------------------

Ladies and Gentlemen:

     I have acted as counsel to ICF Kaiser International, Inc., a Delaware
corporation (the "Company"), and each of Cygna Consulting Engineers and Project
Management, Inc., a California corporation, ICF Kaiser Government Programs,
Inc., a Delaware corporation, PCI Operating Company, Inc., a Delaware
corporation, and Systems Applications International, Inc., a Delaware
corporation (each a "Subsidiary Guarantor" and collectively the "Subsidiary
Guarantors"), in connection with the registration under the Securities Act of
1933, as amended (the "Securities Act"), of, and the offer to exchange (the
"Exchange Offer"), the Company's 12% Senior Notes due 2003, Series B (the
"Exchange Notes"), for its outstanding 12% Senior Notes due 2003, Series A (the
"Old Notes"), and the guarantee of the Exchange Notes by each of the Subsidiary
Guarantors (collectively the "Guarantees").  This opinion is delivered to you in
connection with the Registration Statement on Form S-1 for the aforementioned
Exchange Notes, Exchange Offer and the Guarantees (the "Registration
Statement").  Capitalized terms used herein without definition shall have the
meanings given to them in the Registration Statement.

     In arriving at the opinions expressed below, I have examined and relied on
the originals, or copies certified or otherwise identified to my satisfaction,
or each of (a) the Exchange Notes, (b) the Indenture and (c) the Guarantees,
each of which has been filed as an exhibit to the Registration Statement.
<PAGE>
 
ICF Kaiser International, Inc. and Subsidiary Guarantors

Page 2

     I have assumed for purposes of my opinions hereinafter set forth that (a)
the Indenture has been duly authorized, executed and delivered by the Trustee
and (b) the Trustee has full power, authority and legal right to perform its
obligations under the Indenture.

     In connection with rendering the opinions expressed below, I have examined
and relied upon the originals, or copies authenticated to my satisfaction, of
such public and corporate records, certificates of public officials,
certificates of officers and representatives of the Company and the Subsidiary
Guarantors and other documents and instruments as I have deemed relevant and
necessary as the basis of the opinions hereinafter set forth.  Insofar as this
opinion involves factual matters, I have relied, to the extent I have deemed
proper, upon certificates of officers of the Company and the Subsidiary
Guarantors and certificates of public officials.

     In my examination of all of the foregoing, I have assumed the genuineness
of all signatures, the legal capacity of natural persons, the authenticity of
all documents submitted to me as originals, the conformity to original documents
of all documents submitted to me as certified or photostatic copies and the
authenticity of the originals of such copies.

     Based upon the foregoing and subject to the qualifications, exceptions and
limitations set forth herein, I am of the opinion that when the Registration
Statement shall become effective under the Securities Act, when the Indenture
shall become qualified under the Trust Indenture Act of 1939, as amended, and
when the Exchange Notes shall have been duly executed and authenticated as
specified in the Indenture:

     1.   The Indenture has been duly and validly authorized by the Company and
constitutes the valid and legally binding agreement of the Company, enforceable
against the Company in accordance with its terms.

     2.   The Guarantees have been duly and validly authorized by each of the
Subsidiary Guarantors and (assuming due authentication and delivery of the
Exchange Notes by the Trustee in accordance with the Indenture) each of the
Guarantees constitutes the valid and legally binding agreement of the Subsidiary
Guarantor that issued it, enforceable against such Subsidiary Guarantor in
accordance with its terms.

     3.   The Exchange Notes have been duly and validly authorized by the
Company and, when duly executed and delivered by the Company upon delivery to
the Company of Old Notes in accordance with the terms of the Exchange Offer
(assuming due authentication and delivery of the Exchange Notes by the Trustee
in accordance with the Indenture), will constitute the valid and legally binding
obligations of the Company, enforceable against the Company in accordance with
their terms.

     The enforceability of the Indenture, the Guarantees and the Exchange Notes
is subject in each case to (i) bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to
creditors' rights generally and (ii) general principles of equity (regardless of
whether enforceability is considered in a proceeding at law or in equity) and
the discretion of the court before which any proceeding therefor may be brought.

     This opinion deals only with the specific legal issues it addresses
explicitly.  In rendering this opinion, I express no opinion as to the laws of
any jurisdiction other than the federal laws of the United States, the laws of
the State of New York and the General Corporation Law of the State of Delaware.
I am admitted to practice only in the Commonwealth of Virginia and the District
of Columbia and for purposes of rendering this opinion I have assumed that the
laws of the State of New York are the same in all material respects as the laws
of the Commonwealth of Virginia.

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me under the caption "Legal
Matters" in the Prospectus that is a part of the Registration Statement.

                              Respectfully submitted,

                                                            Exhibit No. 10(a)(1)

                      FIRST AMENDMENT TO CREDIT AGREEMENT

          This First Amendment to Credit Agreement,  dated as of December 17,
1996 (this "Agreement"), is entered into by and among ICF Kaiser International,
Inc.  ("Borrower"), a Delaware corporation, each of its subsidiaries signatories
hereto (each a "Subsidiary Guarantor" and collectively the "Subsidiary
Guarantors"), the banking institutions signatories hereto (each, a "Bank" and
collectively, the "Banks") and Corestates Bank, N.A., as agent for the Banks
under this Agreement (in such capacity, the "Agent").

                                   WITNESSETH

          WHEREAS, Borrower, each Subsidiary Guarantor, the Banks and the Agent
are parties to a Credit Agreement, dated as of May 6, 1996, whereby the Banks
have agreed to provide a revolving credit facility for loans and for letters of
credit;

          WHEREAS, the Borrower and the Subsidiary Guarantors have requested,
and the Banks and the Agent have agreed, to amend the Credit Agreement in
certain respects, as provided herein.

          NOW, THEREFORE, in consideration of the premises and intending to be
legally bound hereby, the parties hereto agree as follows:

1.        Amendment to Credit Agreement

a.        The following definitions are hereby amended in their entirety so that
such definitions, as so amended, shall read as follows:

          "Excluded Transaction" shall mean the redemption on or before January
13, 1997 of the Series 2D Senior Preferred Stock of Borrower from the proceeds
of any one or more of (i) the sale of some or all of Borrower's investment in
the entities owning and operating a pulverized coal injection facility in Gary,
Indiana, (ii) the 1996 Senior Notes and (iii) up to $6,500,000 of Loans
hereunder.

          "Security Agreement" shall mean the Security Agreement, dated as of
May 6, 1996, as amended as of the date hereof.

b.        The following definitions are hereby added to Section 1.1:

          "Amendment Closing Date" shall mean December 17, 1996.

          "1996 Senior Notes" shall mean the Borrower's 12% Senior Notes due
2003, Series A, to be issued December 23, 1996, and all 12% Senior Notes due
2003, Series B, issued in exchange therefor.

          "Overadvance Availability" shall mean, prior to and on March 31, 1997,
$5,000,000, and after March 31, 1997, $0, subject to reductions provided in
Section 2.7 (c).

          "Overadvance Amount"  shall mean, at any time, the amount by which the
unpaid principal amount of all Revolving Credit Loans then outstanding plus the
Letter of Credit Outstandings at such time exceeds the then current Borrowing
Base.

c.        Clauses (3), (4) and (5) of Section 2.1 (a) are hereby amended in
their entirety so that such clauses, as so amended, shall read as follows:

          (3)   Notwithstanding the foregoing, Borrower shall not be entitled to
a Revolving Credit Loan if, after giving effect to such Revolving Credit Loans
to Borrower then outstanding plus the Letter of Credit Outstandings at 
<PAGE>
 
such time would exceed the lesser of (i) the Aggregate Revolving Loan Commitment
or (ii) the then current Borrowing Base plus the Overadvance Availability or (B)
the unpaid principal amount of the Revolving Credit Loans to Borrower then
outstanding would exceed $25,000,000.

          (4)   Except for Revolving Credit Loans which exhaust the full
remaining amount permitted by clause (3) above, and conversions which result in
the conversion of all Revolving Credit Loans subject to a particular interest
rate option, each of which hereof may be in lesser amounts, each Loan when made
and each conversion of Loans of one type into Loans of another type hereunder
shall be in an amount at least equal to $1,000,000, or if greater, then in such
minimum amount plus $1,000,000 multiples.

          (5)   Within the limits of clause (3) above, the Aggregate Revolving
Loan Commitment and the Borrowing Base, Borrower may borrow, prepay (in
accordance with Section 2.8) and reborrow Revolving Credit Loans. All Revolving
Credit Loans shall, in any event, be repaid by Borrower on the Revolving
Termination Date.

d.        Section 2.4(e) is hereby amended in its entirety so that such Section,
as so amended, shall read as follows:

          (e)   Applicable Margins. The margin applicable to Base Rate Loans and
the Loans (in each such case, the "Applicable Margin"), other than the
Overadvance Amount, will be determined from time to time based on the ratio of
EBIT to Consolidated Interest Expense. Upon receipt by the Agent of the
quarterly financial statements required to be delivered pursuant to Section 6.1
(b), the Agent shall determine the ratio of EBIT to Consolidated Interest
Expense for the quarterly period covered by such statements. The Agent shall
thereupon determine the Applicable Margin corresponding to such ratio, in each
case pursuant to the schedule attached as Schedule 2.4(e) hereto. Any adjustment
to the Applicable Margins shall become effective five Business Days following
receipt by the Agent of the financial statements required pursuant to Section
6.1(b) hereof or, if Borrower fails to provide financial statements within the
time period required by Section 6.1 (b) hereof, and such financial statements
cause the Applicable Margins to increase, such adjustment of the Applicable
Margins shall become effective retroactive to the date five Business Days
following the date the financial statements were required under Section 6.1(b)
to be furnished. Any adjustment in such Applicable Margins shall affect the
Applicable Margin of Base Rate Loans then in effect or thereafter made, and
shall apply to the Applicable Margin of LIBO Rate Loans thereafter made.
Overadvance Amounts shall be subject to a Base Rate Margin of 1% and a LIBO Rate
Margin of 2 1/2 %. For purposes of determining the interest rate applicable to
outstanding Loans, the Overadvance Amount shall be included in Base Rate Loans
then outstanding and, to the extent the Overadvance Amount exceeds the Base Rate
Loans then outstanding, LIBO Rate Loans then outstanding.

e.        Section 2.7(c) is hereby amended by inserting, at the end of such
Section, the following sentences:

In addition, the Aggregate Revolving Loan Commitment shall be reduced by
$5,000,000 on March 31, 1997.  Any reduction in the Aggregate Revolving Loan
Commitment pursuant to this Section 2.7(c) shall also result in a corresponding
reduction in the Overadvance Availability.

f.        Section 2.8(a) is hereby amended in its entirety, so for such Section,
as amended, shall read as follows:

          (a)   Mandatory Prepayments.  If at any time the aggregate outstanding
Revolving Credit Loans plus Letter of Credit Outstandings exceed the lesser of
(y)) the then Aggregate Revolving Loan Commitment or (z) the then current
Borrowing Base plus the Overadvance Availability, Borrower shall make a
prepayment of principal in respect of the Base Rate Loans in such amount as is
necessary to assure that the aggregate principal amount of Loans outstanding
immediately after such reduction plus Letter of Credit Outstandings will not
exceed the lesser of the then Aggregate Revolving Loan Commitment and the then
current Borrowing Base plus the Overadvance Availability.  If prepayment in full
as of the Base Rate Loans does not reduce the amount of all Loans outstanding
plus Letter of Credit Outstandings to an amount that will not exceed the lesser
of the then Aggregate Revolving Loan Commitment and the then current Borrowing
Base plus the Overadvance Availability, Borrower shall deposit with the Agent
cash and Discounted Treasuries in an amount sufficient to repay that portion of
the principal amount of LIBO Rate Loans outstanding, with interest thereon
through the end of each applicable Interest Period, as is necessary to assure
that the aggregate principal amount of Loans outstanding immediately after such
reduction of 

                                      -2-
<PAGE>
 
the Base Rate Loans less the principal amount of LIBO Loans repaid by such
collateral plus Letter of Credit Outstandings will not exceed the lesser of the
then Aggregate Revolving Loan Commitment and the then current Borrowing Base
plus the Overadvance Availability, such collateral to be held by the Agent on
behalf of the Banks until each such maturity date and then applied to the
repayment of such Loans. If, upon prepayment in full of the Base Rate Loans and
deposit of cash and Discounted Treasuries in an amount sufficient to repay the
principal amount of the LIBO Rate Loans, the Letter of Credit Outstandings
exceed the lesser of the then Aggregate Revolving Loan Commitment and the then
current Borrowing Base plus the Overadvance Availability, Borrower shall deposit
with the Agent cash and Discounted Treasuries in an amount equal to one hundred
five percent (105%) of the amount by which Letters of Credit Outstandings exceed
the lesser of the then Aggregate Revolving Loan Commitment and the then current
Borrowing Base plus the Overadvance Availability, such collateral to be held by
the Agent on Behalf of the Banks to reimburse the Issuing Bank for the amount of
any Unpaid Drawings. Upon reduction of Letter of Credit Outstandings to an
amount equal to the lesser of the then Aggregate Revolving Loan Commitment and
the then current Borrowing Base plus the Overadvance Availability and if no
Event of Default or Potential Default then exists, any such collateral held for
reimbursement of Unpaid Drawings of Letters of Credit shall be released to
Borrower. If Borrower sells or otherwise disposes of assets requiring a
reduction in the Aggregate Revolving Loan Commitment pursuant to Section 2.7(c)
hereof, Borrower shall use the proceeds of each such sale or disposition to
prepay the Revolving Credit Loans, unless the Required Banks consent in writing
to the waiver of this provision, such waiver being required for each sale or
disposition.

g.        The first sentence of Section 3.5 is hereby amended to read as
follows:

The consolidated financial statements of Borrower and its Subsidiaries as of and
for the nine (9) months ended September 30, 1996, consisting in each case of a
balance sheet, a statement of operations, a statement of shareholders' equity, a
statement of cash flows and accompanying footnotes, present fairly, in all
material respects, the financial position, results of operations and cash flows
of Borrower and its Subsidiaries as of the dates and for the periods referred
to, in conformity with Generally Accepted Accounting Principles.

h.        Section 6.1 is hereby amended by the addition of the following
subsection (k) at the end of such Section.

          (k)   Additional Information during Overadvance Availability. Until
the later of reduction of the Overadvance Availability to $0 and repayment of
the Overadvance Amount (i) as soon as available but no later than twenty-five
(25) Business Days after the end of each month, a consolidated balance sheet of
Borrower and its Subsidiaries and related consolidated statements of operations,
retained earnings and cash flows for such month and for the period from the
beginning of such fiscal year to the end of such month, together with
consolidating information, and a corresponding financial statement for the same
periods in the preceding year certified by the Executive Vice President and
Chief Financial Officer or the Vice President and Treasurer of Borrower as
having been financial statements and weekly statement of cash flow will be in a
form reasonably acceptable to the Agent.

i.        Section 6.11 is hereby amended by the addition, at the end of such
Section of the following phrase:

"and for the redemption of the Series 2D Senior Preferred Stock as and to the
extent provided in the definition of "Excluded Transaction".

j.        Section 7.2 is hereby amended by deleting subsection (e) and replacing
it with new (e) as follows:

          (e)   the 1996 Senior Notes.

k.        Section 7.6 is hereby amended by the addition, at the end of such
Section, of the following:

; provided, however, that no Investment otherwise permitted under any of the
clauses (d), (e) or (f) above (other than an Investment not in excess of
$300,000 in connection with a New York light rail transit proposal) shall be
made after the Amendment Closing Date until the later of reduction of the
Overadvance Availability to $0 and repayment of the Overadvance Amount.

l.        Section 7.10 is hereby amended in its entirety so that such Section,
as so amended, shall read as follows:

          7.10  Modification of Indenture.  Consent to or permit any amendment,
modification or waiver of any material provision or term contained in (a) the
Indenture dated as of January 11, 1994, as supplemented between Borrower and The
Bank of New York, as Trustee, relating to the 12% Senior Subordinated Notes due
2003 issued by Borrower or (b) the Indenture dated as of December 20, 1996
between the Borrower, the guarantors named therein and The Bank of New York, as

shall furnish to the Agent and each of the Banks a certificate signed by the
Executive Vice President and Chief Financial Officer or Vice President and
Treasurer of Borrower certifying that, to the best of such officer's knowledge,
after due inquiry, immediately after such amendment, modification or waiver, (i)
Borrower has complied with all covenants, agreements and conditions in each Loan
Document and each representation and warranty contained in each Loan Document is

warranty had been made on the date of such certificate (except to the extent
such representation or warranty related to a specific prior date), and (ii) no
event has occurred and is continuing that constitutes an Event of Default or
Potential Default.

ended September 30, 1996 and 1995, for the ten months ended December 31, 1995, 
and for the years ended February 28 or 29, 1995, 1994, 1993 and 1992 are set 
forth below (in thousands except ratio). In the years ended February 29, 1992
and February 28, 1994, income from continuing operations before fixed charges
and income taxes (Earnings) were inadequate to cover fixed charges. The
deficiencies were $54.3 million and $12.9 million for the years ended February
29, 1992 and February 28, 1994, respectively.

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned tenders to the Company the principal amount of Old Notes indicated
above.  Subject to, and effective upon, the acceptance for exchange of the Old
Notes tendered with this Letter, the undersigned exchanges, assigns and
transfers to, or upon the order of, the Company all right, title and interest in
and to the Old Notes tendered.

The undersigned constitutes and appoints the Exchange Agent as his or her agent
and attorney-in-fact (with full knowledge that the Exchange Agent also acts as
the agent of the Company) with respect to the tendered Old Notes, with full
power of substitution, to:  (a) deliver certificates for such Old Notes; (b)
deliver Old Notes and all accompanying evidence of transfer and authenticity to
or upon the order of the Company upon receipt by the Exchange Agent, as the
undersigned's agent, of the Exchange Notes to which the undersigned is entitled
upon the acceptance by the Company of the Old Notes tendered under the Exchange
Offer; and (c) receive all benefits and otherwise exercise all rights of
beneficial ownership of the Old Notes, all in accordance with the terms of the
Exchange Offer.  The power of attorney granted in this paragraph shall be deemed
irrevocable and coupled with an interest.

The undersigned hereby represents and warrants that he or she has full power and
authority to tender, exchange, assign and transfer the Old Notes tendered hereby
and that the Company will acquire good and unencumbered title thereto, free and
clear of all liens, restrictions, charges and encumbrances and not subject to
any adverse claim.  The undersigned will, upon request, execute and deliver any
additional documents deemed by the Company to be necessary or desirable to
complete the assignment and transfer of the Old Notes tendered.

The undersigned agrees that acceptance of any tendered Old Notes by the Company
and the issuance of Exchange Notes (together with the guarantees of the
Subsidiary Guarantors (as defined in the Prospectus) with respect thereto) in
exchange therefor shall constitute performance in full by the Company of its
obligations under the Registration Rights Agreement (as defined in the
Prospectus) and that, upon the issuance of the Exchange Notes, the Company will
have no further obligations or liabilities thereunder (except in certain limited
circumstances).  By tendering Old Notes, the undersigned certifies (a) that it
is not an "affiliate" of the Company within the meaning of the Securities Act
(an "Affiliate"), that it is not a broker-dealer that owns Old Notes acquired
directly from the Company or an Affiliate, that it is acquiring the Exchange
Notes offered hereby in the ordinary course of the undersigned's business and
that the undersigned has no arrangement with any person to participate in the
distribution of such Exchange Notes; (b) that it is an Affiliate of the Company
or of the Initial Purchaser of the Old Notes and that it will comply with the
registration and prospectus delivery requirements of the Securities Act to the
extent applicable to it; or (c) that it is a Participating Broker-Dealer (as
defined in the Registration Rights Agreement) and that it will deliver a
prospectus in connection with any resale of the Exchange Notes.  By tendering
Old Notes and executing this Letter of Transmittal, the undersigned further
certifies that it is not engaged in and does not intend to engage in a
distribution of the Exchange Notes.

The undersigned acknowledges that, if it is a broker-dealer that will receive
Exchange Notes for its own account, it will deliver a prospectus in connection
with any resale of such Exchange Notes.  By so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

The undersigned understands that the Company may accept the undersigned's tender
by delivering written notice of acceptance to the Exchange Agent, at which time
the undersigned's right to withdraw such tender will terminate.

The undersigned understands that the Exchange Notes will bear interest from
December 31, 1996, and waives the right to receive any payment in respect of
interest on the Old Notes accrued from December 31, 1996 to the date of issuance
of the Exchange Notes.

                                 INSTRUCTIONS

                         FORMING PART OF THE TERMS AND
                       CONDITIONS OF THE EXCHANGE OFFER

1.  Delivery of this Letter and Certificates.  Certificates for Old Notes or a
    ----------------------------------------                                  
Book-Entry Confirmation, as the case may be, as well as a properly completed and
duly executed copy of this Letter and any other documents required by this
Letter, must be received by the Exchange Agent at one of its addresses set forth
herein on or before the Expiration Date.  The method of delivery of this Letter,
certificates for Old Notes or a Book-Entry Confirmation, as the case may be,
and any other required documents is at the election and risk of the tendering
holder, but except as otherwise provided below, the delivery will be deemed made
when actually received by the Exchange Agent.  If delivery is by mail, the use
of registered mail with return receipt requested, properly insured, is
suggested.

If tendered Old Notes are registered in the name of the signer of this Letter
and the Exchange Notes to be issued in exchange therefor are to be issued (and
any untendered Old Notes are to be reissued) in the name of the registered
holder, the signature of such signer need not be guaranteed.  In any other case,
the tendered Old Notes must be endorsed or accompanied by written instruments of
transfer in form satisfactory to the Company and duly executed by the registered
holder and the signature on the endorsement or instrument of transfer must be
guaranteed by a bank, broker, dealer, credit union, savings association,
clearing agency or other institution (each an "Eligible Institution") that is a
member of a recognized signature guarantee medallion program within the meaning
of Rule 17Ad-15 under the Exchange Act.  If the Exchange Notes and/or Old Notes
not exchanged are to be delivered to an address other than that of the
registered holder appearing on the note register for the Old Notes, the
signature on this Letter must be guaranteed by an Eligible Institution.

Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to tender
Old Notes should contact such holder promptly and instruct such holder to tender
Old Notes on such beneficial owner's behalf.  If such beneficial owner wishes to
tender such Old Notes itself, such beneficial owner must, prior to completing
and executing the Letter of Transmittal and delivering such Old Notes, either
make appropriate arrangements to register ownership of the Old Notes in such
beneficial owner's name or follow the procedures described in the immediately
preceding paragraph.  The transfer of record ownership may take considerable
time.

Holders whose Old Notes are not immediately available or who cannot deliver
their Old Notes or a Book-Entry Confirmation, as the case may be, and all other
required documents to the Exchange Agent on or before the Expiration Date may
tender their Old Notes pursuant to the guaranteed delivery procedures set forth
in the Prospectus.  Pursuant to such procedures:  (i) tender must be made by or
through an Eligible Institution; (ii) prior to the Expiration Date, the
Exchange Agent must have received from the Eligible Institution a properly
completed and duly executed Notice of Guaranteed Delivery (by telegram, telex,
facsimile transmission, mail or hand delivery) (x) setting forth the name and
address of the holder, the description of the Old Notes and the principal amount
of Old Notes tendered, (y) stating that the tender is being made thereby and (z)
guaranteeing that, within five New York Stock Exchange trading days after the
date of execution of such Notice of Guaranteed Delivery, this Letter together
with the certificates representing the Old Notes or a Book-Entry Confirmation,
as the case may be, and any other documents required by this Letter will be
deposited by the Eligible Institution with the Exchange Agent; and (iii) the
certificates for all tendered Old Notes or a Book-Entry Confirmation, as the
case may be, as well as all other documents required by this Letter, must be
received by the Exchange Agent within five New York Stock Exchange trading days
after the date of execution of such Notice of Guaranteed Delivery, all as
provided in the Prospectus under the caption "The Exchange Offer--How to
Tender."

The method of delivery of Old Notes and all other documents is at the election
and risk of the holder.  If sent by mail, it is recommended that registered
mail, return receipt requested, be used, proper insurance be obtained, and the
mailing be made sufficiently in advance of the Expiration Date to permit
delivery to the Exchange Agent on or before the Expiration Date.

                                      -9-
<PAGE>
 
Unless an exemption applies under the applicable law and regulations concerning
"backup withholding" of federal income tax, the Exchange Agent will be required
to withhold, and will withhold, 31% of the gross proceeds otherwise payable to a
holder pursuant to the Exchange Offer if the holder does not provide his or her
taxpayer identification number (social security number or employer
identification number) and certify that such number is correct.  Each tendering
holder should complete and sign the main signature form and the Substitute Form
W-9 included as part of this Letter, so as to provide information and
certification necessary to avoid backup withholding, unless an applicable
exemption exists and is proved in a manner satisfactory to the Company and the
Exchange Agent.

If a holder desires to accept the Exchange Offer and time will not permit a
Letter of Transmittal or Old Notes to reach the Exchange Agent before the
Expiration Date, a tender may be effected if the Exchange Agent has received at
its office listed on the front of this letter on or prior to the Expiration Date
a letter, telegram or facsimile transmission from an Eligible Institution
setting forth the name and address of the tendering holder, the principal amount
of the Old Notes being tendered, the names in which the Old Notes are registered
and, if possible, the certificate number of the Old Notes to be tendered, and
stating that the tender is being made thereby and guaranteeing that within five
New York Stock Exchange trading days after the date of execution of such letter,
telegram or facsimile transmission by the Eligible Institution, the Old Notes,
in proper form for transfer, will be delivered by such Eligible Institution
together with a properly completed and duly executed Letter of Transmittal (and
any other required documents).  Unless Old Notes being tendered by the above-
described method (or a timely Book-Entry Confirmation) are deposited with the
Exchange Agent within the time period set forth above (accompanied or preceded
by a properly completed Letter of Transmittal and any other required documents),
the Company may, at its option, reject the tender.  Copies of a Notice of
Guaranteed Delivery which may be used by Eligible Institutions for the purposes
described in this paragraph are available from the Exchange Agent.

A tender will be deemed to have been received as of the date when the tendering
holder's properly completed and duly signed Letter of Transmittal accompanied by
the Old Notes (or a timely Book-Entry Confirmation) is received by the Exchange
Agent.  Issuances of Exchange Notes in exchange for Old Notes tendered pursuant
to a Notice of Guaranteed Delivery or letter, telegram or facsimile transmission
to similar effect (as provided above) by an Eligible Institution will be made
only against deposit of the Letter of Transmittal (and any other required
documents) and the tendered Old Notes (or a timely Book-Entry Confirmation).

All questions as to the validity, form, eligibility (including time of receipt),
acceptance and withdrawal of tendered Old Notes will be determined by the
Company, whose determination will be final and binding.  The Company reserves
the absolute right to reject any or all tenders that are not in proper form or
the acceptance of which, in the opinion of the Company's counsel, would be
unlawful.  The Company also reserves the right to waive any irregularities or
conditions of tender as to particular Old Notes.  All tendering holders, by
execution of this Letter, waive any right to receive notice of acceptance of
their Old Notes.  The Company's interpretation of the terms and conditions of
the Exchange Offer (including the Letter of Transmittal and the instructions
thereto) will be final and binding.

Neither the Company, the Exchange Agent nor any other person shall be obligated
to give notice of defects or irregularities in any tender, nor shall any of them
incur any liability for failure to give any such notice.

2.  Partial Tenders; Withdrawals.  If less than the entire principal amount of
    ----------------------------                                              
any Old Note evidenced by a submitted certificate or by a Book-Entry
Confirmation is tendered, the tendering holder must fill in the principal amount
tendered in the fourth column of Box 1 above.  All of the Old Notes represented
by a certificate or by a Book-Entry Confirmation delivered to the Exchange Agent
will be deemed to have been tendered unless otherwise indicated.  A certificate
for Old Notes not tendered will be sent to the holder, unless otherwise provided
in Box 5, as soon as practicable after the Expiration Date, in the event that
less than the entire principal amount of Old Notes represented by a submitted
certificate is tendered (or, in the case of Old Notes tendered by book-entry
transfer, such non-exchanged Old Notes will be credited to an account maintained
by the holder with the Book-Entry Transfer Facility).

                                      -10-
<PAGE>
 
If not yet accepted, a tender pursuant to the Exchange Offer may be withdrawn
prior to the Expiration Date.  For a withdrawal to be effective, a written or
facsimile transmission notice of withdrawal must be timely received by the
Exchange Agent at its address set forth on the back cover of the Prospectus
prior to the Expiration Date.  Any such notice of withdrawal must specify the
person named in the Letter of Transmittal as having tendered Old Notes to be
withdrawn, the certificate numbers of Old Notes to be withdrawn, the principal
amount of Old Notes to be withdrawn, a statement that such holder is withdrawing
its election to have such Old Notes exchanged, and the name of the registered
holder of such Old Notes, and must be signed by the holder in the same manner as
the original signature on the Letter of Transmittal (including any required
signature guarantees) or be accompanied by evidence satisfactory to the Company
that the person withdrawing the tender has succeeded to the beneficial ownership
of the Old Notes being withdrawn.  The Exchange Agent will return the properly
withdrawn Old Notes promptly following receipt of notice of withdrawal.  All
questions as to the validity of notices of withdrawals, including time of
receipt, will be determined by the Company, and such determination will be final
and binding on all parties.

3.  Signatures on this Letter; Assignments; Guarantee of Signatures.  If this
    ---------------------------------------------------------------          
Letter is signed by the holder(s) of Old Notes tendered hereby, the signature
must correspond with the name(s) as written on the face of the certificate(s)
for such Old Notes, without alteration, enlargement or any change whatsoever.

If any of the Old Notes tendered hereby are owned by two or more joint owners,
all owners must sign this Letter.  If any tendered Old Notes are held in
different names on several certificates, it will be necessary to complete, sign
and submit as many separate copies of this Letter as there are names in which
certificates are held.

If this Letter is signed by the holder of record and (i) the entire principal
amount of the holder's Old Notes are tendered; and/or (ii) untendered Old Notes,
if any, are to be issued to the holder of record, then the holder of record need
not endorse any certificates for tendered Old Notes, nor provide a separate bond
power.  In any other case, the holder of record must transmit a separate bond
power with this Letter.

If this Letter or any certificate or assignment is 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 proper evidence satisfactory to the
Company of their authority to so act must be submitted, unless waived by the
Company.

Signatures on this Letter must be guaranteed by an Eligible Institution, unless
Old Notes are tendered:  (i) by a holder who has not completed the Box entitled
"Special Issuance Instructions" (Box 4) or "Special Delivery Instructions" (Box
5) on this Letter; or (ii) for the account of an Eligible Institution.  In the
event that the signatures on this Letter or a notice of withdrawal, as the case
may be, are required to be guaranteed, such guarantees must be by an eligible
guarantor institution that is a member of The Securities Transfer Agents
Medallion Program (STAMP),  The New York Stock Exchange Medallion Signature
Program (MSP) or The Stock Exchanges Medallion Program (SEMP).  If Old Notes are
registered in the name of a person other than the signer of this Letter, the Old
Notes surrendered for exchange must be endorsed by, or be accompanied by a
written instrument or instruments of transfer or exchange, in satisfactory form
as determined by the Company, in its discretion, duly executed by the registered
holder with the signature thereon guaranteed by an Eligible Institution.

4.  Special Issuance and Delivery Instructions.  Tendering holders should
    ------------------------------------------                           
indicate, in Box 4 or 5, as applicable, the name and address to which the
Exchange Notes or certificates for Old Notes not exchanged are to be issued or
sent, if different from the name and address of the person signing this Letter.
In the case of issuance in a different name, the tax identification number of
the person named also must be indicated.  Holders tendering Old Notes by book-
entry transfer may request that Old Notes not exchanged be credited to such
account maintained at the Book-Entry Transfer Facility as such holder may
designate.

5.  Tax Identification Number.  Federal income tax law requires that a holder
    -------------------------                                                
whose tendered Old Notes are accepted for exchange must provide the Exchange
Agent (as payor) with his or her correct taxpayer identification number ("TIN"),
which, in the case of a holder who is an individual, is his or her social
security number.  If the

                                      -11-
<PAGE>
 
Exchange Agent is not provided with the correct TIN, the holder may be subject
to a $50 penalty imposed by the Internal Revenue Service.  In addition, delivery
to the holder of the Exchange Notes pursuant to the Exchange Offer may be
subject to back-up withholding.  (If withholding results in overpayment of
taxes, a refund may be obtained.)  Exempt holders (including, among others, all
corporations and certain foreign individuals) are not subject to these back-up
withholding and reporting requirements.  See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 (the
"Guidelines") for additional instructions.

Under federal income tax laws, payments that may be made by the Company on
account of Exchange Notes issued pursuant to the Exchange Offer may be subject
to back-up withholding at a rate of 31%.  In order to prevent back-up
withholding, each tendering holder must provide his or her correct TIN by
completing the "Substitute Form W-9" referred to above, certifying that the TIN
provided is correct (or that the holder is awaiting a TIN) and that:  (i) the
holder has not been notified by the Internal Revenue Service that he or she is
subject to back-up withholding as a result of failure to report all interest or
dividends; (ii) the Internal Revenue Service has notified the holder that he or
she is no longer subject to back-up withholding; or (iii) in accordance with the
Guidelines, such holder is exempt from back-up withholding.  If the Old Notes
are in more than one name or are not in the name of the actual owner, consult
the enclosed Guidelines for information on which TIN to report.

6.  Transfer Taxes.  The Company will pay all transfer taxes, if any, applicable
    --------------                                                              
to the transfer of Old Notes to it or its order pursuant to the Exchange Offer.
If however, the Exchange Notes or certificates for Old Notes not exchanged are
to be delivered to, or are to be issued in the name of, any person other than
the record holder, or if tendered certificates are recorded in the name of any
person other than the person signing this Letter, or if a transfer tax is
imposed by any reason other than the transfer of Old Notes to the Company or its
order pursuant to the Exchange Offer, then the amount of such transfer taxes
(whether imposed on the record holder or any other person) will be payable by
the tendering holder.  If satisfactory evidence of payment of taxes or exemption
from taxes is not submitted with this Letter, the amount of transfer taxes will
be billed directly to the tendering holder.

Except as provided in this Instruction 6, it will not be necessary for transfer
tax stamps to be affixed to the certificates listed in this Letter.

7.  Waiver of Conditions.  The Company reserves the absolute the right to amend
    --------------------                                                       
or waive any of the specified conditions in the Exchange Offer in the case of
any Old Notes tendered.

8.  Mutilated, Lost, Stolen or Destroyed Certificates.  Any holder whose
    -------------------------------------------------                   
certificates for Old Notes have been mutilated, lost, stolen or destroyed should
contact the Exchange Agent at the address indicated above, for further
instructions.

9.  Requests for Assistance or Additional Copies.  Questions relating to the
    --------------------------------------------                            
procedure for tendering, as well as requests for additional copies of the
Prospectus or this Letter, may be directed to the Exchange Agent.

IMPORTANT:  This Letter (together with certificates representing tendered Old
Notes or a Book-Entry Confirmation and all other required documents) must be
received by the Exchange Agent on or before the Expiration Date (as defined in
the Prospectus).

          You may be subject to backup withholding if this interest is $600 or

Exempt payees described above should file Form W-9 to avoid possible erroneous

IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO
THE PAYER.  IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS,
ALSO SIGN AND DATE THE FORM.

Certain payments other than interest, dividends, and patronage dividends, that
are not subject to information reporting are also not subject to backup
withholding.  For details, see the regulations under section 6041, 6041A(a),
6045, and 6050A.

Privacy Act Notice--Section 6109 requires most recipients of dividends, interest
or other payments to give taxpayer identification numbers to payers who must
report the payments to IRS.  IRS uses the numbers for identification purposes.
Payers must be given the numbers whether or not recipients are required to file
tax returns.  Beginning January 1, 1993, payers must generally withhold 31% of
taxable interest, dividend, and certain other payments to a payee who does not
furnish a taxpayer identification number to a payer.  Certain penalties may also
apply.

Penalties

(1)  Penalties for Failure to Furnish Taxpayer Identification Number.--If you
fail to furnish your taxpayer identification number to a payee, you are subject
to a penalty of $50 for each such failure unless your failure is due to a
reasonable cause and not to willful neglect.

(2)  Failure to Report Certain Dividend and Interest Payments.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an under-
payment attributable to that failure unless there is clear and convincing
evidence to the contrary.

(3)  Civil Penalty for False Information With Respect to Withholding.--If you
make a false statement with no reasonable basis which results in no imposition
of  backup withholding, you are subject to a penalty of $500.

(4)  Criminal Penalty for Falsifying  Information.--Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
