Item 5.  Other Events

     On March 9, 1999, The IT Group, Inc. ("IT"), a Delaware corporation,
announced that it had entered into an Asset Purchase Agreement (the
"Agreement"), dated March 8, 1999, with ICF Kaiser International, Inc. ("ICF").
Pursuant to the Agreement, IT will acquire certain assets of the Environmental
and Facilities Management Group ("EFM") of ICF for $82.0 million in cash,
subject to certain adjustments, including, but not limited to, a reduction of
the purchase price by $8.0 million, representing working capital retained by
ICF.  The closing is expected to be completed by early April.

     The acquisition of EFM is an acquisition of the operations of certain
direct and indirect subsidiaries associated with ICF, including, but not limited
to, the stock of certain ICF subsidiaries, which are principally engaged in the
business of overseeing major program management and technical support contracts
for United States government agencies, including the United States Department of
Energy and Defense, and NASA, as well as private sector environmental clients.

     The EFM acquisition is subject to certain conditions, including the
completion of financing arrangements by IT and expiration or early termination
of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended.

     It is currently intended that the financing for the Agreement will be
provided by a private placement pursuant to Rule 144A of the Securities Act of
1933, as amended, of senior subordinated notes in the aggregate amount of $200
million.

     A copy of the IT press release announcing the execution of the Agreement is
filed as an Exhibit to this Current Report on Form 8-K.

     3.1  Place and Date. The closing of the sale and purchase of the Assets

Both parties will use their best efforts to close concurrently with the closing
of Buyer's financing.

     3.2  Initial Payment; Purchase Price. Concurrently with the execution of
this Agreement, Buyer shall pay to ICF $1,000,000 by wire transfer of
immediately available funds as directed by ICF (the "Initial Payment"). The
Initial Payment shall be non-refundable. On the terms and subject to the
conditions set forth in this Agreement, upon the Closing, Buyer shall pay to
Sellers, in accordance with their sale of the Assets, $82,000,000 (the "Purchase
Price") less (a) the sum of (i) an amount equal to the Net Working Capital
        ----

                                       11
<PAGE>
 
Adjusted Purchase Price shall be paid by the wire transfer of immediately
available funds to such bank account or accounts as are specified by ICF in
written instructions given to Buyer at least two business days prior to the
Closing.

     3.3  Allocation of Purchase Price.

          (a) The parties hereto agree to allocate the aggregate consideration
received by Sellers with respect to the Assets, in accordance with Section 1060
of the Code, as mutually agreed to by the parties pursuant to the procedure
described below. Subject to the requirements of any applicable Tax law or
election, all such mutually agreed-to allocations shall be used by each party in
preparing any filings required pursuant to Section 1060 of the Code or any
similar provisions of state or local law and all relevant Income Tax Returns.
Neither Buyer nor Seller will take any position before any taxing authority or
in any judicial proceeding with respect to Income Taxes that is inconsistent
with such mutually agreed-to allocations without the prior written consent of
the other party, in the consenting party's sole discretion. The parties shall in
good faith exercise best efforts to support such mutually agreed-to reported
allocations in any audit proceedings initiated by any taxing authority;
provided, however, that none of Sellers shall have any obligation to pay for an
- --------  -------                                                              
appraisal or in any other way incur unreasonable or extraordinary out-of-pocket
expenses.

          (b) Within the earlier of 150 days after the Closing Date or 30 days
prior to the due date of IRS Form 8594, Buyer will provide to ICF copies of IRS
Form 8594 and any required exhibits thereto (the "Asset Acquisition Statement")
with Buyer's proposed allocation of the consideration received by Sellers with
respect to the Assets. Within 30 days after the receipt of such Asset
Acquisition Statement, ICF will propose to Buyer any changes to such Asset
Acquisition Statement. If ICF shall fail to propose any such changes within such
30-day period, ICF shall be deemed to have accepted the Asset Acquisition
Statement. Thereafter, Buyer will provide to ICF from time to time revised
copies of the Asset Acquisition Statement (each, a "Revised Statement") so as to
report any matters on the Asset Acquisition Statement that require updating.
Within 30 days after the receipt of any Revised Statement, ICF will propose to
Buyer any changes to such Revised Statement. If ICF shall fail to propose any
such changes within such 30-day period, ICF shall be deemed to have accepted the
applicable Revised Statement. Buyer and ICF will in good faith exercise best
efforts to resolve any differences with respect to the Asset Acquisition
Statement or any Revised Statement within 30 days after Buyer's receipt of
notice of objection or suggested changes from ICF.

     3.4  Assumption of Liabilities; Closing Financial Statement.

          Liabilities").

          (b) Two business days prior to the Closing, ICF shall deliver to Buyer
a proposed final statement of the Assets and Assumed Liabilities as of the

of assets and liabilities, the "Closing Financial Statement").

     3.5  Excluded Liabilities. Except as specifically set forth in Section 3.4,

satisfactory in form and substance to Buyer, and shall be effective to vest in
Buyer good title, free and clear of any liens and encumbrances or rights and

shall deliver to Seller such instruments of assumption as shall be satisfactory
in form and substance to Seller to ensure that Buyer has assumed all of the
Assumed Liabilities.

     3.7  Consent of Third Parties. Notwithstanding anything to the contrary in
this Agreement, this Agreement shall not constitute an agreement to assign or
transfer any Governmental Approval, instrument, contract, lease, permit or other
agreement or arrangement or any claim, right or benefit arising thereunder or

assignment or transfer without the consent of a third party would constitute a

thereunder; and any transfer or assignment to Buyer by Seller of any interest
under any such Governmental Approval, instrument, contract, lease, permit or

                                   ARTICLE 4

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     Except as set forth in the Disclosure Schedule delivered to Buyer
contemporaneously herewith (the "Disclosure Schedule"), of which the Schedules
referred to below are a part, and in the documents and other materials
identified in the Disclosure Schedule (it being agreed that any matter disclosed
in the Disclosure Schedule with respect to any section of this Agreement shall
be deemed to have been disclosed with respect to all sections of this
Agreement), and subject to the limitations contained in Article 12, Seller
represents and warrants to Buyer as follows:

     4.1  Organization, Standing, Etc. of Each Business Entity; Corporate
Authorization; Enforceability.

          (a) Each Business Entity is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction where it is
organized and has all requisite corporate power and authority to carry on the
Business as currently conducted by it and to own or lease and to operate the
properties of the Business used by it. Each Business Entity is qualified to do
business and is in good standing in each state of the United States in which the
Business is conducted that requires such qualification and where the failure to
so qualify would have a material adverse effect on the financial condition or
results of operations of the Business. For the purposes of this Agreement, a
"Material Adverse Effect on the Business" or the term "material" or any
variations thereof used in conjunction with the Business means (i) any material
adverse change in, or a material adverse effect on, the assets, liabilities,
business or operations of the Business with a value or effect in excess of
$100,000 in respect of the subject matter of any particular representation or
warranty, or (ii) any event or circumstance that would prevent, materially
hinder or materially delay the consummation of the transactions contemplated by
this Agreement.

          (b) The execution, delivery and performance of this Agreement and all
other documents and instruments executed or to be executed pursuant to this
Agreement (the "Ancillary Documents") by any Seller, and the consummation of the
transactions contemplated hereby and thereby, have been duly authorized by all
necessary corporate and other action on the part of each Seller. This Agreement
and the Ancillary Documents executed or to be executed by Seller have been, or
will have been, at the time of their respective executions and deliveries, duly
executed and delivered by a duly authorized officer of each Seller.

          (c) This Agreement and each Ancillary Document constitutes the valid
and legally binding obligation of each Seller, enforceable in accordance with
its terms, except as such enforceability may be limited by equitable principles
and by applicable bankruptcy, insolvency, reorganization, arrangement,
moratorium or similar laws relating to or affecting the rights of creditors
generally.

                                       15
<PAGE>
 
     4.2  Charter and Bylaws. Copies of the charter and bylaws and other
organizational documents of the Business Entities have been made previously
available to Buyer, and each such copy is true, correct and complete.

     4.3  No Violations. The execution, delivery and performance of this
Agreement and the Ancillary Documents executed or to be executed by Seller, and
the consummation of the transactions contemplated hereby and thereby, will not
cause or result in any violation of or default under any provision (a) of the
charter or bylaws of any Seller, (b) except as set forth on Schedule 4.3, of any
mortgage, indenture, trust, lease, partnership or other agreement or other
instrument, permit, concession, grant, franchise, license, judgment, order,
decree, statute, law, ordinance, rule or regulation applicable to any Seller or
the Business, the result of which, with respect to items identified in clause
(b), would (either individually or in the aggregate) have a Material Adverse
Effect on the Business; or (c) result in the creation or imposition of any Lien
on any of the Assets.

     4.4  Governmental Authorizations and Consents. Except as set forth on
Schedule 4.4, no consents, licenses, approvals or authorizations of, or
registrations or declarations with, any Governmental Authority, agency, bureau
or commission, or any third party, are required to be obtained or made by any
Business Entity in connection with the execution, delivery, performance,
validity and enforceability of this Agreement or any Ancillary Document, other
than (a) a filing with the Federal Trade Commission and the Department of
Justice under the HSR Act, and (b) other consents, licenses, approvals,
authorizations, registrations or declarations, where the failure to obtain such
would not have a Material Adverse Effect on the Business.

     4.5  Compliance with Other Instruments and Laws. No Business Entity is in
violation of any term of its charter or bylaws or other charter documents or,
except as set forth on Schedule 4.5, any mortgage, indenture, instrument or
agreement relating to indebtedness for borrowed money or of any judgment, decree
or order which names such Business Entity, or of any term of any other Assumed
Contract which is among the Assets, which violation, either individually or when
aggregated with all other such violations, would have a Material Adverse Effect
on the Business. To Seller's Knowledge, no Business Entity is in violation of
any Applicable Law applicable to the Business or any of the Assets, which
violation, either individually or when aggregated with all other such
violations, would have a Material Adverse Effect on the Business.

     4.6  December Financial Statements. ICF has delivered to Buyer the
statement of the Assets and Assumed Liabilities and the related statement of
income of the Business (including the results of performance of Contracts
terminated during 1998 that would have been Service Contracts had they been in
effect on the date hereof) for the 12 months ended December 31, 1998 (the
"Financial Statements Date") (such statements hereinafter being referred to as
the "December Financial Statements"). The December Financial Statements are
included in Schedule 4.6 and have been prepared in accordance with the
accounting records and policies of ICF and with GAAP and present fairly in all
material respects the Assets and the Assumed Liabilities of the Business as of
the dates thereof and the results of its operations for the period then ended,

                                       16
<PAGE>
 
except (a) as set forth on Schedule 4.6 and (b) that the December Financial
Statements do not contain all footnote disclosures required by GAAP.

     4.7  Absence of Certain Changes or Events. Except as set forth on Schedule
4.7, since December 31, 1998, except for activities related to the transactions
contemplated by this Agreement and the defaults referred to on Schedule 4.5,
each Business Entity has conducted its operations related to the Business in the
ordinary course of business, and has used its best efforts to maintain the
Business, Assets, its relations with employees, suppliers and licenses and has
maintained its operations related to the Business in accordance with past custom
and practice. Without limiting the generality of the foregoing, except as set
forth on Schedule 4.7, since December 31, 1998, in each case as related to the
Business and whether directly or indirectly:

     assigned any of the Assets, tangible or intangible, other than in the
     ordinary course of business;

     involving more than $100,000 to which any Business Entity is a party or by

     released any right or claim (or series of related rights and claims),
     except for any right or claim (or series of rights or claims) under
     commitments or Assumed Contracts, outside the ordinary course of business;

          (f) no Business Entity has incurred, assumed, guaranteed or discharged
     any obligation or liability, absolute, accrued, contingent or otherwise,
     whether due or to become due, or any indebtedness for borrowed money,
     except current liabilities for trade or business obligations incurred in
     connection with the purchase of goods or services in the ordinary course of
     business inconsistent with prior practice;

          (g) no Business Entity has received any notice of termination of any

thereunder any material default on the part of any Business Entity, and there
does not exist any event, occurrence or condition, including the consummation of
the transactions contemplated hereunder, which (after notice, passage of time,

Entity, which default has had or would have a Material Adverse Effect on the
Business.

decree arising from any action, suit, proceeding or investigation that
individually or in the aggregate would reasonably be expected to have a Material
Adverse Effect on the Business.

          (c) No extensions or waivers of statutes of limitation with respect to

Subsidiary does not file Tax Returns that it is or may be subject to Tax by that
jurisdiction. No power of attorney granted by any of the Transferred
Subsidiaries (other than to the common parent of a consolidated group of which
any such Transferred Subsidiary is a member) is in force. No taxing authority is
conducting any examinations with respect to any of the Transferred Subsidiaries

Schedule 4.14, (i) each of said Permits is in full force and effect, (ii) the
Business is in compliance with the terms, provisions and conditions thereof,
except where the failure to be so in compliance could not reasonably be expected

orders or judicial or administrative actions, investigations or proceedings
adversely affecting any of the Permits nor, to Seller's Knowledge, is there any
valid basis for such an action, and (iv) no condition exists and no event has
occurred which (whether with or without notice, lapse of time or the occurrence
of any other event) would permit the suspension or revocation of any material
Permits other than by expiration of the term set forth therein.

     5.4  Compliance with Other Instruments and Laws. The execution, delivery

judgment, order, decree, statute, law, ordinance, rule or regulation applicable

aggregate) have a material adverse effect on the operations or financial
condition of Buyer and its subsidiaries, taken as a whole, or would materially
impair Buyer's ability to consummate the transactions contemplated hereby (a

enforceability of this Agreement, other than (a) a filing with the Federal Trade

Buyer.

                              COVENANTS OF SELLER

     6.1  Conduct of Business; Additional Assumed Contracts.

          (a) Except as may be otherwise expressly permitted by this Agreement
or with the prior written consent of Buyer, from the date hereof and prior to
the Closing, ICF will, and will cause each Business Entity to: (i) operate the
Business only in the ordinary course; (ii) use best efforts to preserve intact
the organization of the Business; (iii) continue in full force and effect all
existing insurance policies (or comparable insurance) of or relating to the
Business; and (iv) use best efforts to preserve each Business Entity's
relationships with its lenders, suppliers, customers, licensors and licensees
and others having business dealings with any Business Entity relating to the
Business.

          (b) Without limiting the generality of Section 6.1(a), and except as
may be otherwise expressly permitted by this Agreement or with the prior written
consent of Buyer, from 

                                       28
<PAGE>
 
the date hereof through the Closing, ICF shall not permit any Business Entity,
with respect to the Business, to:

               (i) enter into any material transaction in connection with the
          Business outside the ordinary course of business;

               (ii) conduct the Business in a manner that departs materially
          from the manner in which the Business was being conducted prior to the
          date of this Agreement;

               (iii)     except for the Transaction Retention Arrangements, make
          any increase in, or any commitment to increase, the compensation
          payable to any employee of any Business Entity, or create or increase
          the benefits under any Pension Plan, Welfare Plan or Benefit
          Arrangement, except those increases which are reasonable and are in
          the ordinary course of business and consistent with past practices;

               (iv) alter, in any material manner, (x) the manner of keeping its
          books, accounts or records or the accounting practices therein
          reflected, (y) the timing of the payment of its payables from its past
          practices, or (z) the collection and billing of receivables;

               (v) agree to amend or modify any Material Contract other than
          pursuant to the Transaction Retention Arrangements; and

               (vi) agree or otherwise commit, whether in writing or otherwise,
          to do any of the foregoing.

          (c) In connection with the conduct of the Business after the date
hereof, ICF will cause the Business Entities to continue to seek new Contracts
on a basis consistent with past practice. Contracts that result from such
activities shall become Assumed Contracts, provided that if any such Contract is
                                           --------                             
a (i) Service Contract with a contract value in excess of $100,000 or (ii)
Contract that would be considered a Material Contract under the terms of Section
4.11(b), such Contract shall not become an Assumed Contract without the written
consent of Buyer, which consent shall not be unreasonably withheld, delayed or
conditioned. Subject to the requirements of Applicable Law and confidentiality
restrictions, ICF shall, and shall cause the Business Entities to, consult with
Buyer in respect of negotiations concerning Bids and potential Contracts that
would reasonably be expected to have a value in excess of $500,000.

     6.2  Acquisition Proposals.

     After the date hereof through April 14, 1999, ICF shall not (nor will it
permit any of its officers, directors, agents or Affiliates to), directly or
indirectly, (a) solicit, encourage, initiate or participate in any negotiations
or discussions with respect to any offer or proposal to acquire all or
substantially all of the business and properties of the Business, or (b) except
as contemplated 

                                       29
<PAGE>
 
by this Agreement, disclose any information not customarily disclosed to any
Person concerning the business and properties of the Business, afford to any
Person access to the properties, books or records of the Business or otherwise
assist or encourage any Person in connection with any of the activities referred
to in clause (a) above; unless in the case of either clause (a) or (b) above,
ICF shall have received a firm written offer relating to such transaction, not
conditioned upon financing, from a reputable buyer, which offer, based on
consultations with ICF's financial advisers, the Board of Directors of ICF
concludes in good faith is on terms financially superior to the terms offered by
the transaction contemplated by this Agreement and is reasonably capable of
being completed (taking into account all material legal, financial, regulatory
and other aspects of the offer and the Person making the offer) (a "Superior
Proposal"), and the Board of Directors of ICF determines in good faith, after
taking into consideration the advice of its outside legal counsel, that it is
likely to be required to consider such offer in order for its members to comply
with their fiduciary duties under applicable law. After April 14, 1999, upon
written notice to Buyer, ICF may engage in the activities referred to in clauses
(a) and (b) above. After the date hereof, ICF agrees to notify Buyer promptly in
writing if (i) any inquiries or offers relating to an acquisition proposal with
respect to the Business are received by ICF or any of its agents or Affiliates
after the date hereof or (ii) any negotiations or discussions in connection with
a possible acquisition of the Business are sought to be initiated or continued,
indicating in connection with such notice the principal terms and conditions of
any proposals or offers. Thereafter ICF shall keep Buyer informed in writing on
a reasonably current basis of the status and revised terms of any such proposals
or offers and the status of any such negotiations or discussions.

     6.3  Access. Subject to reasonable notice and as permitted by law, each
Seller shall afford to Buyer and its accountants, counsel and other agents and
representatives full access during normal business hours throughout the period
prior to the Closing Date to all of the properties, books, contracts,
commitments and records of the Business and, during such period, each Business
Entity shall furnish promptly to Buyer and its representatives in relation to
the Business access to all other information concerning the business, properties
and personnel of the Business as Buyer may reasonably request. Each Business
Entity shall promptly upon request provide Buyer access to a true, complete and
correct copy of each written agreement or other instrument, together with all
amendments or clarifications thereto, and a true, complete and correct summary
of the terms and conditions of each oral agreement, identified in the Disclosure
Schedule. If access is restricted due to a term in the agreement or by
Applicable Law, each Business Entity shall use its best efforts to secure
consent from the other party(ies) to the agreement to provide such access prior
to Closing with sufficient time for Buyer review. Buyer will treat the documents
and other material and information referred to in this Section 6.3 as
"Confidential Information," as defined in the Confidentiality Agreement between
Buyer and ICF dated August 19, 1998 (the "Confidentiality Agreement").

     6.4  Pension/Employee Matters.

          (a) The Business Entities shall take all necessary actions to vest all
Employees of the Business in their benefits under any Pension Plan maintained by
a Business Entity as of the Closing Date.

                                       30
<PAGE>
 
          (b) The Business Entities shall not take any action that will cause
Buyer to be or become a successor corporation with respect to any Pension Plan
maintained by a Business Entity as of the Closing Date.

          (c) The Business Entities shall take all necessary actions to cause a
distributable event under Section 401(k)(10) of the Code with respect to
Employees of the Business who participate in a Pension Plan of the Business
Entities that permits contributions under Section 401(k) of the Code.

     6.5  Confidentiality. ICF will, and will cause all Business Entities, to
treat all documents and other material and information furnished to it by Buyer
which constitute "Confidential Information" as defined in the Confidentiality
Agreement as "Confidential Information" in accordance with the terms of the
Confidentiality Agreement.

     6.6  Tax Elections. No material new elections with respect to Taxes, or any
material changes in current elections with respect to Taxes, affecting the
Assets or the Transferred Subsidiaries for periods after the Closing Date shall
be made after the date of this Agreement without the prior written consent of
Buyer, in Buyer's sole discretion.

     6.7  Audit Cooperation. The Business Entities will use their best efforts
to cooperate with Buyer in connection with the audit of the December Financial
Statements; provided that the costs of PricewaterhouseCoopers in connection with
            --------                                                            
such audit shall be borne by Buyer.

     6.8  Noncompetition. Between the date hereof and the third anniversary of
the Closing Date, ICF will not, and will not permit its subsidiaries to,
directly or indirectly compete with Buyer for any extension or renewal of any of
the Service Contracts.

     7.1  Confidentiality. Buyer shall hold in strict confidence, and shall
cause each of its Affiliates to hold in strict confidence, all documents and
information obtained with respect to the Business Entities and their Affiliates.
Buyer shall not permit any of such documents or information to be utilized or to
be disclosed or conveyed to any other Person or entity, and Buyer shall comply
in all respects with the provisions of the Confidentiality Agreement. Without
limiting the generality of the foregoing, and except as required by law or
pursuant to valid legal process, Buyer shall not contact any customers or
employees of any Business Entity without the prior consent of an officer of
Seller.

     7.2  Investigation. In conducting its review of the Business, Buyer shall
conduct itself so as to not unreasonably interfere with the Business or with the
performance of any Business Entity's employees.

                                       31
<PAGE>
 
     7.3  Insurance. Buyer shall obtain and continuously maintain, from the
Closing Date until the expiration of the representations, warranties and
covenants pursuant to Section 12.1, insurance policies with respect to the
Business and the Assets on terms and with coverage no less favorable than those
maintained by any Business Entity on the date hereof.

     7.4  Employees.

          (a) Following the Closing Date, the Employees of the Business who are
offered employment by Buyer ("Buyer Employees") shall become eligible to
participate in the employee benefit plans and arrangements maintained by Buyer
("Buyer Benefit Plans"), including severance plans, in the same manner as
similarly situated employees of Buyer. Buyer shall grant Buyer Employees credit
for all service credited by ICF, or any other Seller, for purposes of
eligibility, vesting and the determination of benefits under vacation and
severance pay plans.

          (b) Following the Closing Date, full-time and benefit-eligible part-
time (i.e., employees whose scheduled work hours are 30 or more per week)
Employees of the Business who are not offered employment by Buyer ("Terminated
Employees") shall receive severance and accrued vacation benefits, if any, under
the Welfare Plan, Benefit Arrangements and Transaction Retention Arrangements of
Seller, and Buyer shall reimburse Seller for the payment of any such amounts
which may be due.

          (c) Notwithstanding anything contained herein to the contrary, Buyer
shall have no payment obligations to any Employee of the Business who is, in
good faith, offered employment by Buyer and does not accept such employment. For
purposes of this Section 7.4(c), a "good faith" offer shall mean an offer that
includes (i) a salary of not less than 95% of an employee's current salary, (ii)
employment within 50 miles of an employee's current work location, and (iii) a
position comparable to an employee's current position.

     7.5  Assistance with Respect to Retained Assets. Following the Closing
Date, upon request of any Seller, Buyer will use its best efforts to assist such
Seller in connection with collection of accounts receivable of the Business in
respect of periods prior to the Closing Date (other than Transferred Unbilled
Receivables), the Government Contract Retained Amounts and the Excess SGS
Advances. To the extent Buyer receives payment in respect of such items
following the Closing Date, Buyer shall promptly pay such amounts to such
Seller.

     7.6  Financing Payments. If Buyer shall not have closed the financing
referred to in Section 9.11 on or before the dates referred to below, on each of

                                   ARTICLE 8

documents and notifications in connection with the transactions contemplated by
this Agreement. Buyer and ICF shall diligently and expeditiously comply with the

waivers are required to be obtained from parties to any Material Contracts, in
connection with the consummation of the transactions contemplated by this
Agreement and (ii) in taking such actions or making any such filings, in
furnishing such information as may be required in connection therewith, and in

be required to proffer to, or agree to, sell or hold separate, before or after
the Closing Date, any assets, businesses or any interest in any assets or

to require, a proffer or agreement that would, in the reasonable judgment of
Buyer, be likely to have a Material Adverse Effect on the Business after the

Subject to Applicable Laws relating to the exchange of information, Buyer and
ICF shall have the right to review in advance, and to the extent practicable

Governmental Authority in connection with the other contemplated by this
Agreement.

          8.3 Public Announcements. None of Buyer, ICF nor any of their
Affiliates will issue any press release or make any public statement with
respect to this Agreement or the transactions contemplated hereby, or disclose
the existence of this Agreement to any Person or entity, prior to the Closing
and, after the Closing, will not issue any such press release or make any such

and service marks (collectively, "Names") incorporating "ICF" or "ICF Kaiser" or
any similar Name and to all corporate symbols or logos (collectively, "Logos")
incorporating "ICF" or "ICF Kaiser" or any similar Name. All rights of Seller
and its Affiliates to the same and the goodwill represented thereby and
pertaining thereto are being retained by Seller. Buyer agrees that it will not,
and will cause the Business not to, use the ICF or ICF Kaiser Name or any
similar Name or any Logo incorporating such Name or any similar Name in any
manner, including in connection with the sale of any products or services or
otherwise in the conduct of the Business, except as expressly permitted by
subsection (b) of this Section 8.4.

          (b) For a period of six months from the Closing Date or, with respect
to any Service Contract that requires a novation by the U.S. Government, until
such contract is novated (the "Window Period"), Seller shall and hereby
irrevocably grants, effective as of the Closing Date, on a fully-paid, royalty-
free basis, to Buyer, the right to use the ICF and ICF Kaiser Logos and the ICF
and ICF Kaiser Names in connection with the operation of the Business as
currently conducted including, during the Window Period, to (i) market and sell
all such services and products produced by the Business and (ii) use any other
assets on hand included in the Assets, including, without limitation, any
catalogs, invoices, packaging material or stationery, bearing the ICF and ICF
Kaiser Names or ICF and ICF Kaiser Logos (provided, however, that Buyer 
                                          --------  -------                  

                                       34

incorporating such Names and remove or obliterate such Names and the ICF and ICF
Kaiser Logos from any products or other Assets and clearly and prominently mark

          (c) to furnish to each other such information and assistance as may
     reasonably be requested in connection with the foregoing;

          (d) to novate each Government Contract included in the Assumed
     Contracts on a basis such that ICF or another Seller is designated as the
     party responsible for issues arising under the Government Contract in
     respect of periods prior to the Closing Date;

          (e) to reasonably assist each other as necessary with regard to the

transactions effected pursuant to this Agreement. Each party hereto shall
prepare and timely file all Tax Returns required to be filed in respect of

338(h)(10) Statement") with respect to each Transferred Subsidiary with Buyer's
proposed allocation of modified aggregate 

                                       36
<PAGE>
 
deemed sales price to the assets of each Transferred Subsidiary. Within 30 days
after the receipt of such Section 338(h)(10) Statement, ICF will propose to
Buyer any changes to such Section 338(h)(10) Statement. If ICF shall fail to
propose any such changes within such 30-day period, ICF shall be deemed to have
accepted the Section 338(h)(10) Statement. Thereafter, Buyer will provide to ICF
from time to time revised copies of the Section 338(h)(10) Statement (each, a
"Revised Section 338(h)(10) Statement") so as to report any matters on the
Section 338(h)(10) Statement that require updating. Within 30 days after the
receipt of any Revised Section 338(h)(10) Statement, ICF will propose to Buyer
any changes to such Revised Section 338(h)(10) Statement. If ICF shall fail to
propose any such changes within such 30-day period, ICF shall be deemed to have
accepted the applicable Revised Section 338(h)(10) Statement. Buyer and ICF will
endeavor in good faith to resolve any differences with respect to the Section
338(h)(10) Statement or any Revised Section 338(h)(10) Statement within 30 days
after Buyer's receipt of notice of objection or suggested changes from ICF.

          (c) The modified aggregate deemed sales price with respect to each
Transferred Subsidiary will be allocated to the assets of such Transferred
Subsidiary in accordance with the Section 338(h)(10) Statement or, if
applicable, the last Revised Section 338(h)(10) Statement, provided by Buyer to
ICF pursuant to Subsection 8.9(b) if such statement has been mutually agreed to,
and subject to the requirements of any applicable Tax law or election, all
Income Tax Returns filed by Buyer and ICF will be prepared consistently with
such allocation. Neither Buyer nor ICF will take any position before any taxing
authority or in any judicial proceeding with respect to Income Taxes that is
inconsistent with such mutually agreed-to allocations without the prior written
consent of the other party, in the consenting party's sole discretion. The
parties shall in good faith exercise reasonable efforts to support such mutually
agreed-to reported allocations in any audit proceedings initiated by any taxing
authority; provided, however, that none of Sellers shall have any obligation to
           --------  -------

out-of-pocket expenses.

Subsidiaries in any and all matters relating to the U.S. Federal income tax
liability of the consolidated group of which ICF is the common parent (the

files (i) to determine (x) the manner in which such returns shall be prepared
and filed, including, without limitation, the manner in which any item of
income, gain, loss, deduction or credit shall be reported, (y) whether any
extensions of the due dates for filing of such returns or of the applicable
statutes of limitations may be requested and (z) the elections that will be made
by any member of Seller Consolidated Group, (ii) to file and prosecute any claim
for refund, and (iii) to determine whether any refunds, to which Seller

Subsidiaries hereby irrevocably appoint ICF as agent and attorney-in-fact to
take

                                       37

respect of Taxes of the Transferred Subsidiaries for taxable years or periods
ending after the Closing Date and shall pay or cause to be paid the Taxes shown

Section 8.10.2(b) of this Agreement.

          (d) Buyer shall have the sole right, at its sole expense and for its
sole benefit (except as provided in Section 8.10.2(b) hereof), to prepare and
file any amended Tax Return, or claim for refund, and to prosecute any claim for
refund, with respect to any Taxes paid or payable by the Transferred
Subsidiaries with respect to periods ending after the Closing Date.

          (a) ICF hereby agrees to indemnify and hold the Transferred
Subsidiaries harmless with respect to any Tax Liability of Seller Consolidated
Group where such Liability arises solely by reason of any of the Transferred
Subsidiaries being severally liable for any Taxes of Seller Consolidated Group
pursuant to Treas. Reg. (S) 1.1502-6 or any similar provision of foreign, state
or local law.

          (b) ICF shall indemnify and hold Buyer harmless from and against, and
pay and reimburse Buyer for, any and all Taxes of Seller Consolidated Group or
any member thereof (other than Taxes of any Transferred Subsidiary or with
respect to the Business or the Assets reserved against on the Closing Financial
Statement) for any taxable year or period ending on or before the Closing Date
and the portion of any such Taxes for any taxable year or period ending
thereafter that is attributable to the portion of such year or period prior to

pay and reimburse ICF for, any and all Taxes due by the Transferred Subsidiaries
or any affiliated group of which the Transferred Subsidiaries become members
after the Closing Date for any Taxable year or period beginning on or after the
Closing Date and the portion of any such Taxes for any period beginning before
and ending after the Closing Date that is attributable to the portion of such
year or period beginning on or after the Closing Date, and Buyer shall be

          (d) Notwithstanding anything in this Agreement to the contrary, all of
indemnity obligations set forth in this Section 8.10.2 shall terminate and
expire, and shall cease to be of any force or effect, at 5:00 p.m. (Virginia
time) thirty (30) days after the expiration of the applicable statutes of
limitation, including waivers and extensions thereof, and all liabilities with
respect to the obligations set forth in this Section 8.10.2 shall thereupon be
extinguished; provided, however, that to the extent a written notice asserting
              --------  -------                                               
any claim for indemnification hereunder shall have been given prior to such date
to the Tax Indemnitor, obligations relating to such claim shall survive, until
such claim is fully resolved.

          8.10.3  Tax Liability. Whenever it is necessary for purposes of this
Section 8.10 to determine the Tax Liability of the Transferred Subsidiaries for
a taxable year or period that begins before and ends after the Closing Date, the
determination shall be made by assuming that the entity had a Taxable year that
ended at the close of the Closing Date, except that exemptions, allowances or
deductions that are calculated on an annual basis, such as the deduction for
depreciation, shall be apportioned on a time basis.

          8.10.4  Tax Contests.

          (a) The party obliged to provide indemnification under this Section
8.10 (the "Tax Indemnitor") shall assume and direct the defense or settlement of
any hearing, arbitration, suit or other proceeding (each a "Tax Contest")
commenced, filed or otherwise initiated or convened to investigate or resolve
the existence and extent of a liability with respect to which the Tax Indemnitor
would have an indemnification obligation under this Section 8.10 ("Tax
Indemnification Liability"). The party entitled to be indemnified under this
Section 8.10 (the "Tax Indemnified Party") shall have the right to participate,
as its own cost and expense, in the defense of such Tax Contest, it being
understood that the Tax Indemnitor shall control such Tax Contest.

          (b) The Tax Indemnitor shall pay all out-of-pocket expenses and other
costs related to the Tax Indemnified Liability, including but not limited to
fees for attorneys, accountants, expert witnesses or other consultants retained
by the Tax Indemnitor and/or Tax Indemnified Party (other than fees for
attorneys, accountants, expert witnesses or other consultants retained solely by
the Tax Indemnified Party), and incurred at any time during which the Tax
Indemnitor is controlling and directing the Tax Contest in respect of which such
fees are incurred. To the extent that any such expenses and other costs have

reimburse the Tax Indemnified Party therefor.

          (c) Any Tax Indemnified Party shall give written notice to the Tax
Indemnitor of any settlement proposed by the Taxing authority. The Tax
Indemnitor shall have the right, in its sole discretion, to settle any claim for
which indemnification has been sought under this Section 8.10; provided,
                                                               -------- 
however, that the Tax Indemnitor shall not enter into any settlement,

closing agreement or other agreement with respect to any Tax liability with
respect to the Business, the Assets or the Transferred Subsidiaries without the
prior written consent of the Tax Indemnified Party (such consent not to be
unreasonably withheld or delayed) if such settlement, closing agreement or other
agreement will adversely affect Taxes payable by the Tax Indemnified Party for
taxable periods or portions thereof beginning after the Closing Date.

          8.10.5  Cooperation.

          (a) Seller and Buyer shall provide each other with such assistance and
documents, without charge and in a timely fashion, as may be reasonably
requested by either of them in connection with (i) the preparation of any Tax
Return, (ii) the conduct of any Tax Contest, or (iii) any other matter that is
the subject of this Agreement. Such assistance shall include, without
limitation: (i) the provision on demand of books, records, Tax Returns,
documentation or other information relating to any relevant Tax Return ("Tax
Data"); (ii) the execution of any document that may be necessary or reasonably
helpful in connection with the filing of any Tax Return, or in connection with
any Tax Contest, including, without limitation, the execution of powers of
attorney and extensions of applicable statutes of limitations; and (iii) the use
of reasonable efforts to obtain any documentation from any Governmental
Authority or other Person that may be necessary or reasonably helpful in
connection with the foregoing. Such cooperation shall include, without
limitation, making their respective employees and independent auditors
reasonably available on a mutually convenient basis for all reasonable purposes,
including, without limitation, to provide explanations and background
information and to permit the copying of books, records, schedules, workpapers,
notices, revenue agent reports, settlement or closing agreements and other
documents containing the Tax Data ("Tax Documentation"). If a third party is
retained in connection with any review hereunder, the party retaining such third
party shall be responsible for any fees and expenses for such third party.

          (b) ICF and each other member of Seller Consolidated Group, and Buyer
and the Transferred Subsidiaries, shall retain or cause to be retained the Tax
Data, the Tax Documentation, all Tax Returns, schedules and workpapers, and all
material records or other documents relating thereto, until one year after the
expiration of all applicable statutes of limitations (including any waivers or
extension thereof) with respect to the Taxable periods to which such Tax Returns
and other documents relate or until the expiration of any additional period that
either Buyer or Seller, as the case may be, may reasonably request in writing
with respect to specifically designated material records or documents; provided,
however, that in the event an audit, examination, investigation or other
proceeding has been instituted prior to the expiration date of an applicable
statute of limitations, the Tax Data and Tax Documentation relating thereto
shall be retained until there is a final determination thereof (and the time for
any appeal has expired).

          (c) In order to assist Seller in the preparation of Seller's Tax
Returns, Buyer will report to Seller on a calendar quarterly basis payments made
by Buyer on or after the Closing Date with respect to the accrued vacation
liability assumed by Buyer at Closing. Buyer and Seller agree that vacation is
taken on a FIFO basis. Such reports will be prepared on a FIFO

based on the condition referred to in Section 9.11, Buyer shall on the date of
such termination pay to ICF all of the Financing Payments not paid prior to the
date of termination, whether or not any of such Financing Payments is payable
prior to the date of such termination pursuant to the terms of Section 7.6.
Notwithstanding anything herein to the contrary, (i) if Buyer terminates this
Agreement pursuant to Section 11.1(b) due to circumstances under which Buyer is
expressly entitled to refuse to close the transactions contemplated by this
Agreement under Article 9, except if the reason for such termination is due to
the failure to satisfy the conditions to closing set forth in Section 9.5 or
9.11, (ii) if ICF terminates this Agreement pursuant to Section 11.1(b) due to
the failure to satisfy the condition to closing set forth in Section 10.8, or
(iii) if ICF terminates this Agreement pursuant to Section 11.1(c), ICF shall
immediately refund to Buyer all Financing Payments paid hereunder to ICF by wire
transfer of immediately available funds.

                                  ARTICLE 12

                       CERTAIN REMEDIES AND LIMITATIONS

     12.1 Expiration of Representations, Warranties and Covenants. The covenants
set forth in this Agreement shall terminate and expire, and shall cease to be of
any force or effect, on the Closing Date, and all liability of the parties
hereto with respect to such covenants shall thereupon be extinguished. This
Section 12.1 shall not limit any covenant or agreement of the parties that by
its terms contemplates performance after the Closing Date. All of the
representations and warranties of Seller set forth in this Agreement shall
terminate and expire, and shall cease to be of any force or effect, at 5:00 p.m.
(Virginia time) eighteen (18) months after the Closing Date, and all liability
with respect to such representations and warranties shall thereupon be
extinguished, provided that the representations and warranties of Seller set
              --------                                                      
forth in (a) Section 4.13 shall continue in full force and effect until 30 days
after all applicable statutes of limitations, including waivers and extensions,
have expired with respect to the matters addressed therein, and (b) Section 4.15
shall survive until the third anniversary of the Closing Date.

     12.2 Indemnity by Seller.

          (a) Subject to the provisions of Section 12.1 relating to the survival
of representations and warranties and the other limitations contained herein,
from and after the Closing, ICF agrees to indemnify, defend and hold harmless
Buyer and its Affiliates, officers, directors, employees, agents and
stockholders (collectively, the "Buyer Indemnitees") against the net amount of
all claims, losses, liabilities, damages, deficiencies, costs and expenses,
including, without limitation, losses resulting from the defense, settlement
and/or compromise of a claim and/or demand and/or assessment, reasonable
attorneys', accountants' and expert witnesses' fees, costs and expenses of
investigation, and the costs and expenses of enforcing the indemnification
provided hereunder (hereafter individually a "Loss" and collectively "Losses")
incurred by any of Buyer Indemnitees (after deduction of the amount of any
insurance proceeds recoverable and net of any tax benefit) and arising out of or
relating to: (i) all Excluded Liabilities; (ii) any misrepresentation or
material breach of any representation or warranty made by ICF in this Agreement;
and (iii) any breach of any covenant, agreement or obligation of ICF contained
in this Agreement. Notwithstanding the foregoing, damages shall constitute
Losses for the purpose of this Section 12.2 only to the extent of the direct
damages incurred (excluding consequential damages, whether or not foreseeable).

          (b) Except as set forth below, ICF shall not be required to indemnify
Buyer Indemnitees with respect to any claim for indemnification resulting from
or arising out of matters described in Section 12.2(a)(ii) unless and until the
aggregate amount of all such claims against Buyer Indemnitees exceeds three
percent (3%) of the Purchase Price (the "Threshold") and then Buyer will be
entitled to recover from the first dollar. Claims thereafter may be asserted
regardless of amount; provided, however, that ICF's maximum liability to Buyer
                      --------  -------                                       
Indemnitees under Section 12.2(a)(ii) shall not exceed twenty percent (20%) of
the Purchase Price (the "Cap") in the aggregate. Subject to all other provisions
of this Article 12 (excluding the first and second sentences of this Section
12.2(b)), Seller shall fully indemnify Buyer for all Losses relating to

                                       46
<PAGE>
 
Section 4.23 (Transferred Unbilled Receivables), Prior Assumed Contract
Liabilities and other liabilities arising out of the conduct of the Business
prior to the Closing Date that are not Assumed Liabilities without regard to the
Threshold and the Cap, and such claims shall not count against either the
Threshold or the Cap.

          (c) Buyer acknowledges and agrees that ICF may make and retain copies
of such Books and Records as ICF, in its sole discretion, believes is or may be
necessary to defend claims for Transferred Unbilled Receivables and Prior
Assumed Contract Liabilities.

     12.3 Indemnity by Buyer.

          (a) Subject to the provisions of Section 12.1 hereof relating to the
survival of representations and warranties and the other limitations contained
herein, from and after the Closing, Buyer agrees to indemnify, defend and hold
harmless Seller and each of its Affiliates, officers, directors, employees,
agents and stockholders (collectively, the "Seller Indemnitees") against the net
amount of all Losses incurred by any of Seller Indemnitees (after deduction of
the amount of any insurance proceeds recoverable and net of any tax benefit) and
arising out of or relating to: (i) any Assumed Liabilities; (ii) any material
misrepresentation or material breach of any representation or warranty made by
Buyer in this Agreement; and (iii) any material breach of any covenant,
agreement or obligation of Buyer contained in this Agreement; provided, however,
                                                              --------  ------- 
that Buyer's maximum liability to Seller Indemnitees under Section 12.3(a)(ii)
shall not exceed twenty percent (20%) of the Purchase Price in the aggregate.
Notwithstanding the foregoing, damages shall constitute Losses for the purpose
of this Section 12.3 only to the extent of the direct damages incurred
(excluding consequential damages, whether or not foreseeable).

     12.4 Defense of Third-Party Actions. If either a Buyer Indemnitee, on the
one hand, or a Seller Indemnitee, on the other hand (the "Indemnitee"), receives
notice or otherwise obtains knowledge of any matter or any threatened matter
that may give rise to an indemnification claim against the other party (the
"Indemnifying Party"), then the Indemnitee shall promptly deliver to the
Indemnifying Party a written notice describing such matter in reasonable detail.
The timely delivery of such written notice by the Indemnitee to the Indemnifying
Party shall be a condition precedent to any liability on the part of the
Indemnifying Party under this Article 12 with respect to such matter. The
Indemnifying Party shall have the right, at its option, to assume the defense of
any such matter with its own counsel, but only if the Indemnifying Party
simultaneously agrees to indemnify the Indemnitee for such matter. If the
Indemnifying Party elects to assume the defense of and indemnification for any
such matter, then:

          (a) notwithstanding anything to the contrary contained in this
     Agreement, the Indemnifying Party shall not be required to pay or otherwise
     indemnify the Indemnitee against any attorneys' fees or other expenses
     incurred on behalf of the Indemnitee in connection with such matter
     following the Indemnifying Party's election to assume the defense of such
     matter;

          (b) the Indemnitee shall make available to the Indemnifying Party all
     books, records and other documents and materials that are under the direct
     or indirect control of

                                       47
<PAGE>
 
     the Indemnitee or any of the Indemnitee's agents and that the Indemnifying
     Party considers necessary or desirable for the defense of such matter;

          (c) the Indemnitee shall use its best efforts to take, or cause to be
     taken, at its own cost and expense, all actions and to do, or cause to be
     done, all things necessary or, in the reasonable opinion of the
     Indemnifying Party, desirable to the defense of, or any settlement,
     compromise or adjustment relating to, such matter including (i) supplying
     such factual and technical information as the Indemnitee shall possess as
     the Indemnifying Party shall request, (ii) making available to the
     Indemnifying Party persons employed by the Indemnitee, (iii) executing and
     delivering settlements, waivers, powers of attorney and other agreements or
     documents, (iv) promptly and timely filing any claims, counterclaims and
     other actions and (v) maintain in existence and make available to the
     Indemnifying Party books, records and files of the Indemnitee relating to
     any potential claim;

          (d) the Indemnitee shall otherwise fully cooperate as reasonably
     requested by the Indemnifying Party in the defense of such matter; and

          (e) the Indemnitee shall not admit any liability with respect to such
     matter.

If the Indemnifying Party elects not to assume the defense of and
indemnification for such matter, then the Indemnitee shall proceed diligently to
defend such matter with the assistance of counsel reasonably satisfactory to the
Indemnifying Party, provided, however, that the Indemnitee shall not settle,
                    --------  -------                                       
adjust or compromise such matter, or admit any liability with respect to such
matter, without the prior written consent of the Indemnifying Party, such
consent not to be unreasonably withheld or delayed. This Section 12.4 shall not
apply to matters subject to Section 8.10.4 (Tax Contests).

     12.5 Subrogation. To the extent that the Indemnifying Party makes or is
required to make any indemnification payment to the Indemnitee, the Indemnifying
Party shall be entitled to exercise, and shall be subrogated to, any rights and
remedies (including rights of indemnity, rights of contribution and other rights
of recovery) that the Indemnitee or any of the Indemnitee's affiliates may have
against any other Person with respect to any Losses, circumstances or matter to
which such indemnification payment is directly or indirectly related. The
Indemnitee shall permit the Indemnifying Party to use the name of the Indemnitee
and the names of the Indemnitee's Affiliates in any transaction or in any
proceeding or other matter involving any of such rights or remedies; and the
Indemnitee shall take such actions as the Indemnifying Party may reasonably
request for the purpose of enabling the Indemnitee to perfect or exercise the
indemnifying Party's right of subrogation hereunder.

     12.6 Exclusivity. Except for causes of action which arise from fraud or
willful misconduct, or are subject to indemnification under Section 8.10.2, the
right of each party hereto to assert indemnification claims and receive
indemnification payments pursuant to this Article 12 shall be the sole and
exclusive right and remedy exercisable by such party with respect to any

                                       48
<PAGE>
 
breach by the other party hereto of any representation, warranty or covenant or
failure to pay or perform any Assumed Liability or Excluded Liability, as
applicable.

     12.7 Retention of Records. From and after the date of this Agreement, Buyer
and ICF shall preserve all books, records and other documents, materials and
information relevant to the representations, warranties and covenants set forth
in this Agreement for a period of six years following the date of this Agreement
or for such longer period as the rights of the parties hereunder may exist.

     12.8 Notice as to Representations. Without limiting any of the other
obligations of the respective parties hereunder, if at any time after the date
of this Agreement Buyer shall have any reason to believe that any representation
or warranty made by ICF hereunder may have been untrue, Buyer shall promptly
provide ICF written notice to that effect, indicating the basis for Buyer's
belief that such representation or warranty may have been untrue. For purposes
of this Article 12, Seller shall not be deemed to have breached any
representation or warranty if Buyer, prior to the Closing Date, had knowledge of
the breach, or facts and circumstances constituting or resulting in a breach, of
such representation or warranty, and consummated the purchase of the Business
and the Assets notwithstanding such knowledge.

     12.9 Separate Indemnification for Taxes. Notwithstanding anything contained
in this Agreement to the contrary, indemnification for Tax matters set forth in
Sections 4.13 and 8.10 shall be governed solely by the terms of Section 8.10.2.
To the extent any terms of this Article 12 and Section 8.10.2 are deemed to be
inconsistent with respect to any Tax matters, the terms of Section 8.10 shall
govern such matter.


                                  ARTICLE 13

                                 MISCELLANEOUS

     13.1 Material Adverse Effect. Any adverse change, event or effect that is
proximately caused by conditions affecting the United States or international
economy generally shall not be taken into account in determining whether there
has been or would be a Material Adverse Effect on the Business or a Material
Adverse Effect on Buyer (unless such conditions adversely affect the Business
Entities or Buyer, as the case may be, in a materially disproportionate manner).
Any adverse change, event or effect that is proximately caused by any industry
in which Buyer or the Business Entities competes shall not be taken into account
in determining whether there has been or would be a Material Adverse Effect on
Buyer or Material Adverse Effect on the Business (unless such conditions
adversely affect the Business Entities or Buyer, as the case may be, in a
materially disproportionate manner). Any adverse change, event or effect that is
proximately caused by the announcement or pendency of the sale of the Business
and the Assets shall not be taken into account in determining whether there has
been or would be a Material Adverse Effect on Buyer or a Material Adverse Effect
on the Business. Any adverse change, event or effect that is proximately caused
by any breach by Buyer or the Business Entities of any covenant or obligation
set forth in this Agreement shall not be taken into account in determining
whether

                                       49
<PAGE>
 
there has been or would be a Material Adverse Effect on the Business or Material
Adverse Effect on Buyer, respectively.

     13.2 Memorandum; Disclaimer of Projections. The Business Entities make no
representation or warranty to Buyer except as specifically made in this
Agreement. In particular, although the Business Entities make no representation
or warranty to Buyer with respect to the certainty or accuracy of any financial
projection or forecast delivered by or on behalf of any Business Entity to
Buyer, ICF, and ICF on behalf of each Business Entity, prepared such financial
projections and forecasts in good faith and has no reason to believe that such
financial projections or forecasts are materially incorrect or inaccurate.
Notwithstanding this, Buyer acknowledges that (a) there are uncertainties
inherent in attempting to make such projections and forecasts, (b) it is
familiar with such uncertainties, and (c) it is taking full responsibility for
making its own evaluation of the adequacy and accuracy of all such projections
and forecasts so furnished to it.

     13.3 Further Assurances. Each party agrees, at any time and from time to
time after the Closing Date, upon reasonable request from the other party, to
do, execute, acknowledge and deliver, as appropriate, such further acts, deeds,
assignments, transfers, conveyances and powers of attorney as may reasonably be
required for the better assigning, transferring, granting, conveying, assuring
and confirming to such other party, or its successors and assigns, of any of the
assets, properties or liabilities to be assigned to it or retained by such party
as provided herein.

     13.4 Expenses. If the purchase of the Assets is consummated or if this
Agreement is terminated, ICF and Buyer shall pay their own respective expenses
and costs incidental to the preparation of this Agreement, the performance and
compliance with all agreements contained in this Agreement to be performed or
complied with by them and the consummation of the transactions contemplated
hereby, and none of such costs and expenses shall be or become liabilities of
the Transferred Subsidiaries or be considered Assumed Liabilities.

     13.5 Notices. All notices, requests, demands, waivers and other
communications required or permitted to be given under this Agreement shall be
in writing and shall be deemed to have been duly given if (a) delivered
personally, (b) mailed by first-class, registered or certified mail, return
receipt requested, postage prepaid, (c) sent by next-day or overnight mail or
delivery or (d) sent by facsimile transmission or telegram. All such notices,
requests, demands, waivers and other communication shall be deemed to have been

certified or registered mail, on the seventh business day after the mailing
thereof, (iii) if by next-day or overnight mail or delivery, on the day
delivered, (iv) if by facsimile or telegram, on the next day following the day
on which such facsimile or telegram was sent, provided that a copy is also sent
                                              --------

     Any party may give any notice, instruction or communication in connection
with this Agreement using any other means (including personal delivery, telecopy
or ordinary mail), but no such notice, instruction or communication shall be
deemed to have been delivered unless and until it is actually received by the
party to whom it was sent. Any party may change the address to which notices,

     13.6 Assignment. No party may assign or otherwise transfer this Agreement
or any of its rights hereunder to any Person or entity without the prior written
consent of Buyer and ICF, which consent shall not be unreasonably withheld or
delayed. Notwithstanding the foregoing, Buyer may assign all or any portion of
its rights under this Agreement to any wholly-owned subsidiary of Buyer. Subject
to the foregoing, this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their successors and assigns.

     13.7 Entire Agreement; Amendment; Governing Law; Etc. This Agreement
(together with the Exhibits and Schedules hereto) and the Confidentiality
Agreement embody the entire agreement and understanding among the parties hereto
with respect to the subject matter hereof. This Agreement may be amended,
modified, waived, discharged or terminated only by (and any consent hereunder
shall be effective only if contained in) an instrument in writing signed by the
party against which enforcement of such amendment, modification, waiver,
discharge, termination or consent is sought. This Agreement shall be construed
in accordance with and governed by the laws of the Commonwealth of Virginia as
it applies to contracts to be performed entirely within the Commonwealth of
Virginia.

     13.8 Severability. Any term or provision of this Agreement that is invalid
or unenforceable in any jurisdiction, as to such jurisdiction, shall be
ineffective to the extent of such invalidity or unenforceability, without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction.

     13.9 Dispute Resolution and Arbitration. In the event that any dispute
arises between the parties pertaining to the subject matter of this Agreement,
and the parties, through the senior management of Buyer and ICF, are unable to
resolve such dispute within a reasonable time through negotiations and mediation
efforts by senior executives of both parties (which shall include the active
involvement of the chief financial officers of Buyer and ICF), such dispute
shall be resolved as set forth in this Section 13.9.

          (a) The procedures of this Section 13.9 may be initiated by a written
notice ("Dispute Notice") given by one party ("Claimant") to the other, but not
before thirty (30) days have passed during which the parties have been unable to
reach a resolution as described above. The Dispute Notice shall be accompanied
by (i) a statement of the Claimant describing the dispute in reasonable detail
and (ii) documentation, if any, supporting the Claimant's position on the
dispute. Within twenty (20) days after the other party's ("Respondent") receipt
of the Dispute Notice and accompanying materials, the parties shall submit the
dispute to mediation in the Washington, D.C. area under the rules of the
American Arbitration Association. All negotiations

                                       52
<PAGE>
 
and mediation procedures pursuant to this paragraph (a) shall be confidential
and treated as compromise and settlement negotiations and shall not be
admissible in any arbitration or other proceeding.

          (b) If the dispute is not resolved as provided in paragraph (a) within
sixty (60) days after the Respondent's receipt of the Dispute Notice, the
dispute shall be resolved by binding arbitration. Within the sixty-day period
referred to in the immediately preceding sentence, the parties shall agree on a
single arbitrator to resolve the dispute. If the parties fail to agree on the
designation of an arbitrator within said sixty-day period, the American
Arbitration Association in the Washington, D.C. area shall be requested to
designate the single arbitrator. If the arbitrator becomes disabled, resigns or
is otherwise unable to discharge the arbitrator's duties, the arbitrator's
successor shall be appointed in the same manner as the arbitrator was appointed.

          (c) Except as otherwise provided in this Section 13.9, the arbitration
shall be conducted in accordance with the Commercial Rules of the American
Arbitration Association, which shall be governed by the United States
Arbitration Act.

          (d) Any resolution reached through mediation and any award arising out
of arbitration (i) shall be binding and conclusive upon the parties; (ii) shall
be limited to a holding for or against a party, and affording such monetary
remedy as is deemed equitable, just and within the scope of this Agreement;
(iii) may not include special, incidental, consequential or punitive damages;
(iv) may in appropriate circumstances include injunctive relief; and (v) may be
entered in court in accordance with the United States Arbitration Act.

          (e) Arbitration shall not be deemed a waiver of any right of
termination under this Agreement, and the arbitrator is not empowered to act or
make any award other than based solely on the rights and obligations of the
parties prior to termination in accordance with this Agreement.

          (f) The arbitrator may not limit, expand or otherwise modify the terms
of this Agreement.

          (g) The laws of the Commonwealth of Virginia shall apply to any
mediation, arbitration, or litigation arising under this Agreement.

          (h) Each party shall bear its own expenses incurred in any mediation,
arbitration or litigation, but any expenses related to the compensation and the
costs of any mediator or arbitrator shall be borne equally by the parties to the
dispute.

          (i) A request by a party to a court for interim measures necessary to
preserve a party's rights and remedies for resolution pursuant to this Section
13.9 shall not be deemed a waiver of the obligation to mediate or of the
agreement to arbitrate.

                                       53
<PAGE>
 
          (j) The parties, their representatives, other participants and the
mediator or arbitrator shall hold the existence, content and result of mediation
or arbitration in confidence.

          (k) Notwithstanding the foregoing, this Section 13.9 shall not apply
to disputes with respect to the allocation for Income Tax purposes pursuant to
Sections 3.3(b) or 8.9. In the event the parties cannot agree to such
allocations, each party will file Tax Returns with respect to such allocations
as it, in its sole discretion, determines.

     13.10  Jurisdiction; Court Proceedings; Waiver of Jury Trial. Subject to
the provisions of Section 13.9, any suit, action or proceeding against any party
to this Agreement arising out of or relating to this Agreement shall be brought
in any Federal or state court located in the Commonwealth of Virginia and each
of the parties hereby submits to the exclusive jurisdiction of such courts for
the purpose of any such suit, action or proceeding. A final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law. To
the extent that service of process by mail is permitted by Applicable Law, each
party irrevocably consents to the service of process in any such suit, action or
proceeding in such courts by the mailing of such process by registered or
certified mail, postage prepaid, at its address for notices provided for herein.
Each party irrevocably agrees not to assert (a) any objection which it may ever
have to the laying of venue of any such suit, action or proceeding in any
Federal or state court located in the Commonwealth of Virginia and (b) any claim
that any such suit, action or proceeding brought in any such court has been
brought in an inconvenient forum. Each party waives any right to a trial by
jury, to the extent lawful.

     13.11  No Other Duties. The only duties and obligations of the parties are
as specifically set forth in this Agreement, and no other duties or obligations
shall be implied in fact, law or equity, or under any principle of fiduciary
obligation.

     13.12  Reliance on Counsel and Other Advisors. Each party has consulted
such legal, financial, technical or other experts as it deems necessary or
desirable before entering into this Agreement. Each party represents and
warrants that it has read, knows, understands and agrees with the terms and
conditions of this Agreement.

     13.13  Third-Party Rights. Except as expressly provided in Article 12 with
respect to Indemnitees, the parties do not intend to confer any benefit
hereunder on any Person other than the parties hereto and their respective
successors in interest.

     13.14  Exhibits and Schedules. Each of the Exhibits and Schedules referred
to herein and attached hereto is an integral part of this Agreement and is
incorporated herein by this reference.

     13.15  Counterparts. This Agreement may be executed in several
counterparts, each of which is an original, but all of which shall constitute
one instrument.

                                       54

HEADLINE:  The IT Group, Inc. Agrees to Acquire ICF Kaiser's Environment and 
Facilities Management Group;
Substantial Earnings Accretion of $0.20 Per Share on an Annual Basis Driven By 
Synergies;
Adds $500 Million in Backlog and Private Sector Diversification

DATELINE:  PITTSBURGH, March 9

BODY:
     The IT Group, Inc.  (NYSE: ITX)  (formerly International Technology 
Corporation) announced today it has signed a definitive purchase agreement to 
acquire certain assets of the Environment and Facilities Management Group (EFM) 
of ICF Kaiser International, Inc., (NYSE: ICF) for $82 million in cash.  The 
purchase price will be reduced by $8 million, representing working capital 
retained by ICF Kaiser International and is subject to certain other
adjustments. The acquisition does not include ICF Kaiser's 50% interest in
Kaiser-Hill Company, LLC, which is the management and integration contractor on
the Department of Energy's Rocky Flats Environmental Technology Site in
Colorado. The acquisition of EFM is subject to certain conditions, including the
completion of financing arrangements by The IT Group, and receiving clearances
under Hart-Scott-Rodino. The acquisition will be financed from a private
placement of senior subordinated notes. Closing is expected in April.

     EFM is a leading provider of environmental and facilities management and 
technical support services for U.S. Government agencies, particularly the U.S. 
Departments of Defense (DOD), Energy (DOE), and NASA as well as private sector 
environmental clients.

     Anthony J. DeLuca, chief executive officer and president of The IT Group, 
said, "The acquisition of EFM complements our growth and diversification
strategy. EFM adds $500 million of strategically important and substantially
cost-reimbursable backlog, primarily the Sacramento and Baltimore Total
Environmental Restoration Contracts (TERCs) with the U.S. Army Corps of
Engineers, as well as major commercial client relationships in diverse
industries." Mr. DeLuca went on to say, "Once synergies of $10 million are
achieved, the acquisition is anticipated to add $120 million in revenue, $20
million in operating cash flow and $0.20 earnings per share on an annual basis.
Earnings per share accretion of $0.10 is expected in 1999."

     "The IT Group's outsourced services business will be enhanced by EFM's 23% 
interest in the Space Gateway Support joint venture, which provides facilities

operations and management support for the National Aeronautics and Space
Administration (NASA) and the U.S. Air Force at the Kennedy Space Center, Cape
Canaveral, Patrick Air Force Base, Fla., and other sites. This contract has
potential value over a 10-year period of $2.2 billion to all partners in the
joint venture. We believe the experience gained from the NASA contract will
place The IT Group in a stronger position to benefit from the large and emerging
outsourcing and privatization market," Mr. DeLuca concluded.

     The IT Group, Inc. is a leading group of diversified services companies, 
with more than 6,300 employees in more than 80 offices, offering a full range of
consulting, facilities management, engineering and construction and remedial 
services.  The IT Group's common stock and depositary shares are traded on the 
New York Stock Exchange under the symbols ITX and ITXpr, respectively.  More
