     THIS MASTER TRANSACTION AGREEMENT (this "Master Agreement") is entered into
as of July 6, 2000, by and between HATCH ASSOCIATES, INC., a Delaware

                                    RECITALS

     WHEREAS, Kaiser, directly or through various Affiliates (as defined in
Exhibit A), including the Sellers (as defined in Exhibit A), is engaged in the
Business (as defined in Exhibit A);

     WHEREAS, Buyer wishes to purchase and acquire from Kaiser, and Kaiser
wishes to sell, assign and transfer to Buyer, the Transferred Assets (as defined
in Section 2.1), including without limitation the capital stock of the
Transferred Subsidiaries, and Buyer has agreed to assume the Assumed Liabilities
(as defined in Section 2.3), all for the Purchase Price (as defined in Section
3.2), and upon the terms and subject to the conditions, herein set forth;

     WHEREAS, Kaiser expects to implement the transactions contemplated by this
Master Agreement through its voluntary bankruptcy case (the "Bankruptcy Case")
pursuant to Chapter 11 of Title 11 of the United States Code (the "Bankruptcy
Code") in the United States Bankruptcy Court for the District of Delaware (the

     WHEREAS, the transactions contemplated in this Master Agreement involve a
sale, other than in the Ordinary Course of business, of certain of Kaiser's
assets and properties out of Kaiser's bankruptcy estate pursuant to Bankruptcy

     NOW, THEREFORE, in consideration of the premises and of the

     rights described on Schedule 2.2(a) (the "Excluded Intellectual Property");

           (b)   the rights in intellectual property, intangible property
     rights, license agreements and software licenses not within the definition

     with respect to such insurance policies;

           (h)   all rights to causes of action, lawsuits, claims and demands
     listed on Schedule 2.2(h);

     portion thereof prior to the Closing Date;

           (j)   the right to occupy leased premises used by the Business,

     the properties, assets, contracts and rights identified on the Disclosure
     Schedule or in the Closing Financial Statements) and which are not used
     primarily in the Business.

For the avoidance of doubt, in Sections 2.2(f), (n) and (o) where certain
categories of Excluded Assets are expressly described as those being specific
either to the Business or to any other assets otherwise transferred hereby, the
term "Excluded Assets" shall (i) include properties, assets, contracts and

not include any properties, assets, contracts and rights of the Business
identified in the Disclosure Schedules or reflected in the Closing Financial
Statements.

     2.3   Assumption of Liabilities. Subject to the terms and conditions set
forth herein, at the Closing, Buyer shall assume and agree to pay, honor,
perform and discharge when due the Liabilities and obligations relating to the
Transferred Assets and the Business (other than the Excluded Liabilities) which
are described as follows:

           (a)   all Liabilities and obligations of the Sellers to be performed
     from and after the Closing Date under or relating to the Assumed Contracts
     and the Transferred Facilities, including, without limitation, any guaranty
     by Kaiser or an Affiliate of Kaiser under an Assumed Contract;

           (b)   all Liabilities and obligations relating to or arising out of
     the conduct of the Business on or after the Closing Date;

           (c)   pursuant to the Assumed Contracts, all payments required to be
     made pursuant to Section 365(b)(i) of the Bankruptcy Code, whether
     necessary to cure defaults or otherwise allow the assumption and assignment
     of the Assumed Contracts (the "Cure Obligations");

           (d)   all Liabilities and obligations of Sellers to be assumed by
     Buyer in accordance with the terms of Article 6; and

                                      -5-
<PAGE>

           (e)   all Liabilities reflected on the Closing Financial Statements,
     or to any extent that such Liabilities were incurred subsequently in a
     manner permitted under Section 7.1 of the Master Agreement, or otherwise
     listed on Schedule 2.3(e).

The Liabilities and obligations described in Section 2.3 are collectively
referred to as the "Assumed Liabilities."  For the avoidance of doubt, all
Liabilities and obligations of each of the Transferred Subsidiaries shall remain
in that Transferred Subsidiary consistent with the sale of the capital stock of
the Transferred Subsidiary.

     2.4   Excluded Liabilities. Except as specifically set forth in Section 2.3
and the Transaction Documents, Buyer shall not assume or in any way be
responsible for, and the Sellers shall remain responsible for, the debts,
claims, commitments, liabilities and obligations of Sellers (other than those of
the Transferred Subsidiaries) and the Business (the "Excluded Liabilities"),
including the following:

           (a)   except to the extent reflected on the Closing Financial
     Statements, all Tax liabilities, including penalties and interest, in
     respect of periods prior to the Closing Date;

           (b)   indebtedness for borrowed money relating to the conduct of the
     Business for all periods prior to the Closing Date, except as reflected on
     the Closing Financial Statements;

           (c)   Liabilities arising directly out of the Excluded Assets;

           (d)   inter-company payables and receivables between the Business and
     the balance of Sellers' business arising from the conduct of the Business
     prior to the Closing Date;

           (e)   payroll obligations of the Business in respect of periods prior
     to the Closing Date;

           (f)  obligations under any Seller Benefit Plan, except as
     specifically provided in Section 2.3(d) and Article 6;

           (g)  the Liabilities, if any, listed on Schedule 2.4;

           (h)  any action, suit, proceeding, claim or investigation involving
     any of the Sellers, other than those of the Transferred Subsidiaries; and

           (i)  obligations relating to the Nova Hut project.

For the avoidance of doubt, all of the Liabilities and obligations of each
Transferred Subsidiary will remain with that Transferred Subsidiary consistent
with the sale of the capital stock of the Transferred Subsidiary.

                                  THE CLOSING

     3.1   Place and Date. The closing of the sale and purchase of the
Transferred Assets (the "Closing") and the assumption of the Assumed Liabilities
shall take place at 10:00 a.m., local time, not later than the third business
day following the satisfaction or waiver of the conditions referred to in
Articles 11 and 12 at the offices of Squire, Sanders & Dempsey L.L.P., 1201
Pennsylvania Avenue, N.W., Washington, D.C. or such other time and place upon
which the parties may agree. The day on which the Closing actually occurs is
sometimes referred to herein as the "Closing Date." Notwithstanding the actual
time of Closing on the Closing Date, the Closing shall be deemed to have
occurred as of 12:01 a.m., local time, on the day of the Closing.

     3.2   Purchase Price. On the terms and subject to the conditions set forth
in this Master Agreement, at Closing, Buyer shall pay to Sellers the sum of U.S.
$8,000,000 (the "Purchase Price"), less any cash Deposit, by wire transfer of
immediately available funds to an account or accounts designated by Kaiser;
provided however, that the Purchase Price shall be subject to adjustment as set
-------- -------
forth in Section 3.8. In addition, after Closing and notwithstanding anything
herein to the contrary Buyer shall pay or cause to be paid to Kaiser the first
U.S. $1 million of incentive fee payable to Buyer or any Subsidiary or Affiliate
of Buyer and not otherwise received by Kaiser or any Sellers (other than a
Transferred Subsidiary) under the contract with Kaiser Aluminum and Chemical
Corporation relating to the Gramercy project, exclusive of the U.S. $500,000 fee
received on or before June 2, 2000, regardless of whether received prior to or
following Closing, and Buyer shall enter into a reasonable arrangement with
Kaiser Aluminum and Chemical Corporation and Kaiser prior to Closing to
implement this provision.

     3.3   Deposit. Within two business days of execution of this Master
Agreement, Buyer shall pay to Sellers an amount equal to U.S.$375,000 (the
"Deposit") by wire transfer of immediately available funds to an account
designated by Kaiser where it shall be held in a segregated interest-bearing
escrow account until Closing. In lieu of a Deposit, Buyer may, in its sole
discretion, deliver a letter of credit to Kaiser in a form reasonably
satisfactory to Kaiser from a commercial bank in the United States in an amount
equal to the Deposit. At Closing, any cash Deposit shall be applied and the
Purchase Price reduced by such amount.

     3.4   Allocation of Purchase Price.

           (a)   The parties shall allocate the aggregate consideration received
     by Sellers with respect to the Transferred Assets in accordance with
     Section 1060 of the Tax Code (including without limitation the shares of
     capital stock of the Transferred Subsidiary), 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 Tax Code or any similar provisions
     of foreign, state or local law and all relevant Income Tax Returns. Neither
     Buyer nor Sellers will take any position before any taxing authority or in
     any judicial proceeding with respect to Income Taxes that is

                                      -7-
<PAGE>

     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 exercise commercially 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 pay for an appraisal or in any
     other way incur unreasonable or extraordinary out-of-pocket expenses.

           (b)   Within 10 business days after the Closing Date, Buyer will
     provide to Kaiser copies of IRS Form 8594 and any required exhibits thereto
     with Buyer's proposed allocation of the consideration received by Sellers
     with respect to the Transferred Assets. Within 60 days after the receipt of
     such statement, Kaiser will propose to Buyer any changes to such statement.
     If Kaiser shall fail to propose any such changes within such 60-day period,
     then Kaiser shall be deemed to have accepted such statement.

           (c)   If Buyer and Kaiser cannot agree on an allocation of the
     consideration received by Sellers with respect to the Transferred Assets,
     then Buyer and Kaiser shall promptly submit such differences to the
     independent accounting firm, Ernst & Young, and the decision of such
     accounting firm with respect to the resolution of such differences shall be
     conclusive and binding on the parties hereto, absent manifest error. The
     fees and expenses of such accounting firm shall be shared equally by Buyer
     and Kaiser. Kaiser and Buyer agree that any resolution of this allocation
     process shall be read into and form part of this Master Agreement.

           (d)   Kaiser will use its commercially reasonable efforts to expedite
     this Section 3.4 process to facilitate the registration of the stock of the
     Australian Transferred Subsidiaries, including without limitation
     attempting to reach a resolution with Buyer of this aspect of the
     allocation issue as soon as practicable after execution and delivery of the
     Master Agreement and in no event later than the fifteenth day prior to the
     due date for the filing of the related stamp duty. If the resolution
     process is not completed by such date through no fault of Buyer, then Buyer
     shall select an independent arbitrator who shall, upon reviewing the
     materials presented to him, render a decision, and such decision shall be
     conclusive and binding absent manifest error.

     3.5  Deliveries. At the Closing, (a) Buyer shall deliver to or as directed
by Kaiser the Purchase Price and the agreements, instruments of assumption,
certificates and other documents required to be delivered by Buyer pursuant to
Article 12 and (b) Sellers shall deliver to Buyer the agreements, instruments of
transfer, certificates and other documents required to be delivered by Sellers
pursuant to Article 11.

                                      -8-
<PAGE>

     3.6   Closing Financial Statements. Not less than seven (7) days prior to
the Sale Hearing, Kaiser shall deliver to Buyer an updated set of financial
statements similar to the Financial Statements (the "Closing Financial
Statements"), prepared as of the most recent available business day prior to its
delivery date. The Closing Financial Statements shall be prepared in a manner
consistent with the Financial Statements and the terms of this Master Agreement
and shall only reflect the Transferred Assets and Assumed Liabilities as of the
date reflected thereon on a basis consistent with the Financial Statements,
including without limitation the estimate of working capital accounts. The
Closing Financial Statements will be derived from a combination of system
reports and working capital estimates (including without limitation accounts
receivable, work-in-process, accounts payable and cash of Transferred
Subsidiaries). Kaiser shall make, and shall cause its Subsidiaries to make,
financial personnel, records and information available to Buyer to assist Buyer
in confirming the information contained in the Closing Financial Statements. The
parties shall discuss the resolution of any open issues promptly with a view to
achieving resolution prior to the Sale Hearing. At the time of the Sale Hearing,
the calculation of Net Book Value shall be deemed final to the extent that any
and all objections are resolved.

     3.7   Consents of Third Parties. Notwithstanding anything to the contrary
in this Master Agreement, this Master Agreement shall not constitute an
agreement to assign or transfer any Consent from a Governmental Authority,
instrument, contract (including Contracts which fit within the definition of the
Assumed Contracts), lease, or other agreement or arrangement or any claim, right
or benefit arising thereunder or resulting therefrom, to the extent that such
assignment or transfer or an attempt to make such an assignment or transfer
cannot be made pursuant to Section 365 of the Bankruptcy Code without the
consent or approval of a third party. In the event any such consent or approval
is not obtained on or prior to the Closing Date, the applicable Seller shall
cooperate with Buyer in any lawful arrangement proposed by Buyer to provide that
Buyer shall receive the benefits under any such Consent, instrument, contract,
lease or other agreement or arrangement, provided, however, that Buyer shall
                                         --------  -------
undertake to pay, perform, discharge or satisfy the corresponding liabilities
and obligations for the enjoyment of such benefit to the extent Buyer would have
been responsible therefor if such consent or approval had been obtained.
Notwithstanding anything to the contrary in this Section 3.7, nothing in this
Section 3.7 shall reduce or otherwise affect the obligation of Sellers to cause
the Assumed Contracts to be assumed and assigned to Buyer as required by the
other provisions of this Master Agreement.

     3.8   Closing Date Adjustment.

           (a)   The Purchase Price will be reduced, dollar for dollar, at the
     Closing to the extent that the Net Book Value of the Business as identified
     in the Closing Financial Statements ("Closing Net Book Value") is less than
     U.S. $6,685,000.  The Purchase Price will be increased, dollar for dollar,
     at the Closing to the extent that the Closing Net Book Value of the
     Business is more than U.S. $ 6,685,000.  Notwithstanding anything herein to
     the contrary, no Purchase Price adjustment pursuant to Section 3.8 shall be
     made if the difference between the Net Book Value reflected on the
     Financial Statements and the Closing Net Book Value is not greater than
     U.S. $200,000; provided, however, that if the amount exceeds the U.S.
                    --------  -------
     $200,000 amount, then the Purchase Price adjustment called for

                                      -9-

     herein will be made dollar-for-dollar for the entire amount of the
     difference between Net Book Value reflected on the Financial Statements and
     the Closing Net Book Value.

                                   ARTICLE 4

                    REPRESENTATIONS AND WARRANTIES OF KAISER

     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 Master Agreement
shall be deemed to have been disclosed with respect to all other sections of
this Master Agreement if its relevance to such other sections is reasonably
discernable from its disclosure), and subject to the limitations contained in
Section 14.1, as of the date of this Master Agreement, Kaiser makes to Buyer the
following representations and warranties.

     4.1   Organization, Standing, Etc. of Sellers. Each Seller is a corporation
duly incorporated and 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 Seller is
qualified to do business in each jurisdiction in which the Business is conducted
that requires such qualification by such Seller and where the failure to so
qualify would have a Material Adverse Effect on the Business. For the purposes
of the Transaction Documents, a "Material Adverse Effect on the Business" means
any material adverse change in, or material adverse effect on, the assets,
liabilities, business or operations of the Transferred Assets or the Business
taken as a whole. Each Seller (other than the Transferred Subsidiaries) is
currently a debtor-in-possession in the Bankruptcy Case pursuant to the
Bankruptcy Code, and retains full authority and power to operate its business
and affairs pursuant to sections 1107 and 1108 of the Bankruptcy Code, with no
trustee, examiner, facilitator or other officer or agent with similar authority
or powers to a trustee, examiner or facilitator having been appointed in such
Bankruptcy Case.

     4.2   Corporate Authorization; Enforceability.

           (a) Subject to any required approval by the Bankruptcy Court, the
     execution, delivery and performance of this Master Agreement and all other
     documents executed or to be executed pursuant to this Master Agreement by
     any Seller, and the consummation of the Contemplated Transactions
     (including without limitation the transfer of the capital stock of the
     Transferred Subsidiaries) have been duly authorized by all necessary
     corporate action on the part of each Seller.  Subject to any required
     approval by the Bankruptcy Court, this Master Agreement and the Ancillary
     Agreements executed or to be executed by a 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 such Seller.

                                     -10-
<PAGE>

          (b) Subject to any required approval by the Bankruptcy Court, this
     Master Agreement and each Ancillary Agreement executed or to be executed by
     a Seller constitutes, or at the time executed by a Seller will constitute,
     the valid and legally binding obligation of each Seller, enforceable in
     accordance with its terms.

     4.3  Charters and Bylaws; Capitalization of Transferred Subsidiaries.
Copies of the charters and bylaws and other organizational documents of the
Sellers and the Transferred Subsidiaries have been made previously available to
Buyer, and each such copy is true, correct and complete.  All returns,
particulars, filings, notices and other documents required to be delivered by
the Australian Transferred Subsidiaries to the Australian Securities and
Investments Commission or other government agency, whether federal, state, local
or foreign, have been duly delivered, except where the failure to make such
delivery would not have a Material Adverse Effect on the Business.  The
execution, delivery and performance of this Master Agreement and the Ancillary
Agreements executed or to be executed by Sellers and the consummation of the
Contemplated Transactions (including without limitation the transfer of the
capital stock of the Transferred Subsidiaries) will not cause or result in any
violation of or default under any provision of the charter or bylaws of any
Seller.  The minute books, registers and all other books and records of each
Transferred Subsidiary (whether or not required to be kept or maintained) comply
with legal requirements and are complete and accurate in all respects, except
where such noncompliance, inaccuracy or incompleteness would not have a Material
Adverse Effect on the Business.  Each Seller has complied in all material
respects with its charter and by-laws except where such noncompliance would not
have a Material Adverse Effect on the Business.  Schedule 4.3 sets forth the
authorized and outstanding capital stock of the Transferred Subsidiaries, all of
which is owned beneficially and of record by one or more of the Sellers or by a
nominee whose actions with respect thereto are under the direction of one or
more Sellers.  Except as set forth on Schedule 4.3, none of Kaiser or any of the
Transferred Subsidiaries has any outstanding securities convertible into or
exercisable for any shares of capital stock of any Transferred Subsidiary, nor
does it have any outstanding rights to subscribe for or to purchase, or any
options for the purchase, or any arrangements providing for the issuance
(contingent or otherwise), of, or any calls against, commitments by or claims
against it of any character relating to, any shares of capital stock of any
Transferred Subsidiary or any securities convertible into or exchangeable or
exercisable for any shares of capital stock of any Transferred Subsidiary.

     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 or any third
party are required to be obtained or made by any Seller in connection with the
execution, delivery, performance, validity and enforceability of this Master
Agreement or any Ancillary Agreement, other than (a) any required Bankruptcy
Court approval, 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  Financial Statements. Kaiser has delivered to Buyer the following
financial statements, each as of March 31, 2000 (the "Financial Statements
Date"): (a) pro forma statements of the Transferred Assets and Assumed
Liabilities, other than those of the Transferred Subsidiaries; (b) balance
sheets for the Transferred Subsidiaries; and (c) related statements of revenue
and direct expense for the period January 1, 2000 through March 31, 2000 (such
statements hereinafter being referred to as the "Financial Statements"). The
Financial

                                    - 11 -
<PAGE>

Statements have been prepared in accordance with the accounting records and
policies of Kaiser and with GAAP, and fairly present in all material respects
the Transferred Assets and the Assumed Liabilities of the Business as of the
dates thereof, except as agreed to by the parties and attached hereto as
Schedule 4.5.

     4.6  Absence of Certain Changes or Events. Since the Financial Statements
Date, each Seller has conducted its operations related to the Business in the
Ordinary Course of business except: (i) as set forth on Schedule 4.6, (ii) the
filing of the Bankruptcy Case and any actions taken in connection therewith, and
(iii) activities related to the Contemplated Transactions. No meeting has been
convened or resolution proposed, or petition presented, and no order has been
made, for the winding-up of any Transferred Subsidiary. No receiver, receiver
and manager, provisional liquidator, liquidator or other officer of the court
has been appointed in relation to any Transferred Subsidiary.

     4.7  Title to Transferred Assets.

          (a) Except as set forth on Schedule 4.7, and except for real and
     personal property subject to leases or licenses, each Seller has (i) good
     title to or other valid ownership rights in the Transferred Assets and in
     the case of leases or licenses, a good and valid leasehold or license
     interest and (ii) the Transferred Assets are free of all liens, claims or
     encumbrances.  At the Closing, Sellers shall have the right to transfer
     such title, leasehold interests and license rights to Buyer pursuant to the
     Contemplated Transactions, free of any liens, claims and encumbrances
     except as set forth on Schedule 4.7.

          (b) Schedule 2.1(e) sets forth all personal property leases which
     constitute Assumed Contracts.  There exist no defaults by any Seller
     (except for defaults resulting from the commencement of the Bankruptcy
     Case) or, to Sellers' Knowledge, any default or threatened material default
     by any third party thereunder, that has affected or could reasonably be
     expected to affect the rights and privileges of any Seller under an any
     such personal property lease and which would result in a Material Adverse
     Effect on the Business.  Except as provided on Schedule 2.1(e), the
     assumption by Buyer of such personal property leases and the consummation
     of the Contemplated Transactions shall not result in any default under any
     such lease or impose any penalty on Buyer which default or penalty could
     reasonably be expected to cause a Material Adverse Effect on the Business.

          (c) This Section 4.7 does not apply to the Transferred Intellectual
     Property.

     4.8  Transferred Intellectual Property.

          (a) The Sellers own, or are licensed or otherwise possess the right to
     use, all the Transferred Intellectual Property, and the Transferred
     Intellectual Property, together with the Excluded Intellectual Property, is
     all the intellectual property necessary to conduct the Business
     substantially as currently conducted by the Sellers in all material
     respects.

                                    - 12 -
<PAGE>

          (b) Schedule 2.1(c) includes a list of patents, registered copyrights,
     registered trademarks, registered trade names and registered service marks,
     and any pending applications therefor, included in the Transferred
     Intellectual Property.

          (c) To the Sellers' Knowledge, except as set forth on Schedule 4.8(c),
     no claims with respect to the Transferred Intellectual Property have been
     asserted and are pending (i) to the effect that the sale, licensing or use
     of any of the products or services of the Business infringes any other
     party's valid copyright, trademark, service mark, trade secret or other
     intellectual property right, (ii) against the use by any Seller of any
     trademarks, service marks, trade names, trade secrets, copyrights, patents,
     technology, know-how or computer software programs or applications used in
     the Business as currently conducted, or (iii) challenging the ownership or
     use by any Seller or any of the Transferred Intellectual Property that any
     Seller owns or uses or purports to own or use, nor, to Sellers' Knowledge,
     is there a valid basis for such a claim described in this Section 4.8(c).

          (d) To Sellers' Knowledge, none of the Transferred Intellectual
     Property is subject to any outstanding order, ruling, decree, judgment or
     stipulation by or with any court, arbitrator or administrative agency which
     would impair the ability of Buyer to utilize the Transferred Intellectual
     Property or otherwise impair its value in any manner which would result in
     a Material Adverse Effect on the Business.

     4.9  Assumed Contracts. Kaiser has made available to Buyer a copy or
description of all outstanding Assumed Contracts constituting:

          (a)  All customer contracts and open purchase orders of the Business
     with a reasonably expected value in excess of U.S. $200,000 per annum;
          (b)  All pending bids for customer contracts with a reasonably
     expected value in excess of U.S. $200,000 per annum;

     incorporated or unincorporated;
          (g)  All agreements for the purchase by a Seller of equipment
     specific to the Business involving outstanding commitments in excess of
     U.S. $125,000;

                                    - 13 -
<PAGE>

          (h)  All notes and installment obligations and other instruments and
     contracts specific to the Business and relating to any borrowing of, or
     issuance of letters of credit for, an amount in excess of U.S. $125,000 by
     one or more Sellers;
          (i)  All leases of real or personal property involving payments of
     more than U.S. $125,000 per annum to be assumed by Buyer; and
          (j)  All agreements materially limiting the freedom of a Seller to
     compete in the Business with any Person or other entity or in any
     geographical area, and any other Contract which is material to the
     Business.

A list or description of each of the items described above (the "Material
Contracts") is set forth on Schedule 4.9.  As of the date of this Master
Agreement, except as disclosed on Schedule 4.9, all Material Contracts are in
full force and effect.

     4.10 Litigation. Except as set forth on Schedules 4.10 and 4.12 and other
than the Bankruptcy Case, there are no actions, suits, proceedings or
governmental investigations pending against any Seller or, to Sellers'
Knowledge, overtly threatened, in any jurisdiction anywhere in the world
involving the Business or the Transferred Assets, at law or in equity or before
any Governmental Authority, or that have been settled, dismissed or resolved on
or since March 31, 2000, that would reasonably be expected to have a Material
Adverse Effect on the Business following the Closing Date. No Seller is subject
to any judgment, stipulation, order or 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
following the Closing Date. Except for the Bankruptcy Case, no Seller is subject
to any winding-up, receivership or other similar proceedings which relate to
insolvency.

     4.11 Licenses and Permits. Each Seller has all licenses, permits and other
authorizations from Governmental Authorities necessary for the conduct of the
Business as conducted by the Sellers prior to the date hereof (collectively
"Permits"), except where the failure to have such Permits could not reasonably
be expected to result in a Material Adverse Effect on the Business. Except as
set forth on Schedule 4.11, (a) each of said Permits is in full force and
effect, (b) 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 to result in a Material Adverse Effect on the Business,
(c) to Sellers' Knowledge there are no outstanding violations, notices of
noncompliance, judgments, consent decrees, orders or judicial or administrative
actions, investigations or proceedings adversely affecting any of said Permits,
and (d) to Sellers' Knowledge 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. Sellers make no
representation or warranty with respect to the transferability of the Permits to
Buyer.

     4.12 Environmental Compliance. Except as set forth in Schedule 4.12, to
Sellers' Knowledge the conduct of the Business by Sellers and any Transferred
Facility owned, leased or operated by any Seller has at all times complied and
currently complies in all material respects with all Environmental Laws, except
where the failure to so comply would not reasonably be

                                    - 14 -
<PAGE>

expected to result in a Material Adverse Effect on the Business. "Environmental

Conservation Recovery Act, the Occupational Health and Safety Act, the

Seller nor any officer, employee or agent of any Seller, or any other Person
acting on their behalf, has, directly or indirectly, since the date of formation
of such Seller, respectively, given, offered, solicited or agreed to give, offer
or solicit any contribution, gift, bribe, rebate, payoff, influence payment,
kickback or other payment, regardless of form and whether in money, property or
services, to any customer, supplier, governmental employee or other Person who
is or may be in a position to help or hinder the Business in connection with the
conduct of the Business (a) which subjected or could reasonably be expected to
have subjected a Seller to any material damage or penalty in any civil, criminal
or governmental litigation or proceeding, (b) which, if not given in the past,
could reasonably be expected to have had a Material Adverse Effect on the
Business, (c) which, if not continued in the future, could reasonably be
expected to have a Material Adverse Effect on the Business or subject a Seller
to suit or penalty in any private or governmental litigation or proceeding, (d)
for any purposes described in Section 162(c) of the Tax Code, or (e) for the
purpose of establishing or maintaining any concealed fund or concealed bank
account.

     4.14 Personnel Matters.

          (a) Sellers have heretofore provided to Buyer a list of all of the
     employees for which Buyer will be responsible pursuant to Section 2.3(d)
     and Article 6 (such employees, collectively, "Employees of the Business"),
     which list is attached hereto as Schedule 4.14(a), and their respective job
     titles and current salaries or wages.

          (b) Except as set forth on Schedule 4.14(b), to Sellers' Knowledge
     there are no material employment-related disputes, grievances, or
     disciplinary actions pending or threatened, by or between any of the
     Sellers and any Employees of the Business.

                                    - 15 -
<PAGE>

          (c) All currently effective personnel policies and manuals of the
     Sellers are listed on Schedule 4.14(c) and true, accurate, and complete
     copies of all such written personnel policies and manuals have been made
     available to Buyer.

     4.15 Labor Matters. This Section 4.15 does not extend to the subject
matter of Section 4.16. Except as set forth on Schedule 4.15, in relation to the
conduct of the Business:

          (a) No Seller is obligated by, or subject to, any order of the U.S.
     National Labor Relations Board, the Australian Industrial Relations
     Commission and the Federal Court or other foreign or U.S. labor board or
     administration, or any unfair labor practice decision.

          (b) No Seller is a party or is subject to any pending or, to Sellers'
     Knowledge, threatened labor or civil rights dispute, controversy or
     grievance or any unfair labor practice proceeding with respect to claims
     of, or obligations of, any employee or group of employees.  No Seller has
     received any notice that any labor representation request is pending or is
     threatened with respect to Employees of the Business.

          (c) Each Seller is in compliance in all material respects with all
     Applicable Laws respecting employment and employment practices, terms and
     conditions of employment and wages and hours.

          (d) To Sellers' Knowledge, no Employees of the Business or former
     employee of any Seller has any claim against any Seller (whether under
     Applicable Law, pursuant to any employment agreement, or otherwise) on
     account of, or for: (i) overtime pay, other than for the current payroll
     period; (ii) wages or salary (excluding bonuses and amounts accruing under
     any pension or profit-sharing plan, including but not limited to any
     Benefit Arrangement (as such term is defined in Section 4.16.1(a))) for a
     period other than the current payroll period; or (iii) vacation, time off
     or pay in lieu of vacation or time off, other than vacation or time off (or
     pay in lieu thereof) earned in respect of the current or past fiscal year
     of Sellers or accrued on the Closing Financial Statements.

     4.16 Seller Benefit Plans.

          4.16.1  United States.

          (a) Schedule 4.16.1 lists and identifies (i) each employee pension
     benefit plan, as defined in Section 3(2) of ERISA (a "Pension Plan"); (ii)
     each employee welfare benefit plan, as defined in Section 3(1) of ERISA (a
     "Welfare Plan"); and (iii) each compensation and employment arrangement,
     including, but not limited to, any fringe benefit, incentive compensation,
     stock option, stock purchase, bonus, severance, deferred compensation, and
     supplemental executive compensation plan or employment agreement (a
     "Benefit Arrangement"), that is maintained by a Seller for Employees of the
     Business based in the United States or to which a Seller is obligated to
     make contributions for their benefit (collectively, the "U.S. Benefit
     Plans").  Copies of all U.S. Benefit Plans have been provided or made
     available to Buyer, including, but not limited to (i) each Pension Plan and
     any related trust agreement (including all amendments to such Pension Plan
     and

                                    - 16 -
<PAGE>

     trust) and its most recent summary plan description, the most recent
     determination letter issued by the IRS, and (ii) each Welfare Plan and
     Benefit Arrangement and any related insurance contracts or other funding
     arrangement, administrative services agreement and summary plan description
     and the most recent annual report on Form 5500 required to be filed with
     the IRS in respect of any Pension Plan, Welfare Plan and Benefit
     Arrangement.  Except for the 1999 and 2000 contributions to the Pension
     Plans which by law are not yet required to be made, all contributions have
     been made to the Pension Plans.  Except as disclosed on Schedule 4.16.1, no
     Seller maintains or contributes to any Welfare Plan that provides benefits
     to employees after termination of employment other than as required by Part
     6 of Title I of ERISA.

          (b) Except as disclosed on Schedule 4.16.1, neither any Seller nor any
     ERISA Affiliate is obligated to contribute to any multiemployer plan, as
     defined in Section 3(37) of ERISA nor has been obligated to contribute to
     any multiemployer plan, at any time during the most recent five years, and,
     to Sellers' Knowledge, for any prior period.  As used herein, the term
     "ERISA Affiliate" shall mean a (i) corporation which is a member of the
     same controlled group of corporations (within the meaning of Section 414(b)
     of the Tax Code) as Kaiser, (ii) partnership or other trade or business
     (whether or not incorporated) under common control (within the meaning of
     Section 414(c) of the Tax Code) with Kaiser, (iii) member of the same
     affiliated service group (within the meaning of Section 414(m) of the Tax
     Code) as Kaiser, (iii) any corporation described in clause (i) above or any
     partnership or trade or business described in clause (ii) above, and (iv)
     any other entity which is required to be aggregated with Kaiser pursuant to
     the provisions of Section 414(o) of the Tax Code.  With respect to any such
     multiemployer plan, no Seller or ERISA Affiliate had incurred, or is
     reasonably likely to incur, any withdrawal liability under Title IV of
     ERISA, nor is any such plan in reorganization.

          (c) No Pension Plan is subject to Title IV of ERISA.  No liability
     under Subtitle C or D of Title IV of ERISA has been or is expected to be
     incurred by any Seller or any ERISA Affiliate with respect to any "single-
     employer plan," within the meaning of Section 4001(a)(15) of ERISA,
     currently or formerly maintained by Kaiser or any ERISA Affiliate.  All
     contributions required to be made by any ERISA Affiliate to any employee
     benefit plan subject to Section 412 of the Tax Code or Section 302 of ERISA
     have been timely made.  No employee benefit plan subject to Section 412 of
     the Tax Code sponsored, maintained or contributed to by Kaiser or any ERISA
     Affiliate has an "accumulated funding deficiency" (whether or not waived)
     within the meaning of Section 412 of the Tax Code or Section 302 of ERISA
     and no ERISA Affiliate has an outstanding funding waiver.

          (d) Each Pension Plan which is intended to be qualified under Section
     401(a) of the Tax Code as currently in effect has been determined by the
     IRS to be so qualified and each trust related to any such Pension Plan has
     been determined to be exempt from federal income tax under Section 501(a)
     of the Tax Code.  There have been no prohibited transactions (as described
     in Section 406 or Section 4975 of the Tax Code) with respect to any Pension
     Plan for which there is any outstanding liability.  No material litigation
     or administrative or other proceedings involving the U.S. Benefit Plans has
     occurred which would reasonably be expected to have a Material Adverse
     Effect on the Business.

          (e) Each U.S. Benefit Plan has been administered in accordance with
     its terms and Applicable Law except where the failure to be so administered
     would not have a Material Adverse Effect on the Business.

          4.16.2  Non-U.S. Employee Benefit Plans.

          (a) Except as set forth on Schedule 4.16.2, with respect to all
     Employees of the Business whose employment is based outside of the United
     States, none of the Sellers presently maintains, contributes to or has any
     liability under any material non-U.S. bonus, incentive compensation, profit
     sharing, retirement, pension, group insurance, death benefit, health,
     disability, stock option, stock purchase, savings, deferred compensation,
     severance pay or termination pay, welfare or other employee benefit or
     fringe benefit plan, program or arrangement, excluding any foreign
     government sponsored or mandated plan, program or arrangement affecting
     such employees (including without limitation compulsory superannuation
     under the Superannuation Guarantee (Administration) Act 1992) ("Government
     Sponsored or Mandated Plans").  The plans, programs and arrangements set
     forth on Schedule 4.16.2 are referred to herein as the "Non-U.S. Employee
     Benefit Plans."

          (b) With respect to each of the Non-U.S. Employee Benefit Plans,
     Kaiser has made or will, prior to the Closing Date, make available to Buyer
     copies of:

               (i) The plan documents, including any related trust agreements or
          insurance contracts, including amendments thereto, or a written
          summary of the terms and conditions of the plan if there is no written
          plan document.

               (ii) With respect to any Non-U.S. Employee Benefit Plan
          maintained primarily for the benefit of employees of a Seller, the
          most recent actuarial valuations and financial statements, if any.

          (c) The Non-U.S. Employee Benefit Plans and Government Sponsored or
     Mandated Plans administered by Sellers have been administered and are in
     material compliance with all material requirements of Applicable Law and
     the terms of each such plan except where such failure would not have a
     Material Adverse Effect on the Business; any Non-U.S. Employee Benefit Plan
     which is intended to be qualified under applicable law or registered or
     approved by a Governmental Authority has been determined to be so
     qualified, registered or approved by the appropriate Governmental
     Authority; and nothing has occurred between the date of the last such
     determination and the Closing Date to cause the appropriate Governmental
     Authority to revoke such determination or which would materially adversely
     affect the continuing qualified, registered or approved status of such Non-
     U.S. Employee Benefit Plan, except where such revocation or change in
     status would not have a Material Adverse Effect on the Business.

          (d) All contributions (including premiums) required by law or contract
     to have been paid or accrued, under or with respect to the Non-U.S.
     Employee Benefit Plans and Government Sponsored or Mandated Plans to the
     Closing Date (including periods from

                                    - 18 -
<PAGE>

     the first day of the then current plan year to the Closing Date) will have
     been paid or accrued prior to the Closing Date except to the extent failure
     to pay or accrue such contributions would not be reasonably expected to
     have a Material Adverse Effect on the Business.

          (e) The accrued benefits provided under each Non-U.S. Employee Benefit
     Plan and Government Sponsored or Mandated Plans providing retirement,
     severance or similar benefits (to the extent established and formally
     communicated to employees), determined as of the Closing Date, will not
     exceed the fair market value as of such date of the assets applicable to
     such Non-U.S. Employee Benefit Plan or Government Sponsored or Mandated
     Plan, or the book reserve, balance sheet reserve or other reserve with
     respect thereto as of the Closing Date.  Notwithstanding the foregoing, the
     only amounts so required to be so funded or reserved shall be the amounts
     required to be funded, reserved or provided for in conformity with
     generally accepted accounting principles in the applicable country.  For
     this purpose, "accrued benefits" means the present value of all retirement,
     severance or similar benefits (as described above) under a plan recognizing
     salary and service to Closing.

          (f) There are no material pending or, to Sellers' Knowledge,
     threatened claims (other than routine claims for benefits), investigations,
     litigation or other enforcement actions against Sellers or any of their
     officers, directors, employees or agents, with respect to any of the Non-
     U.S. Employee Benefit Plans, nor is there any other liability with respect
     to such plans except those incurred in the normal course of operation or
     those which would not have a Material Adverse Effect on the Business.

          (g) No material improvement in the benefits accrued or provided under
     the Non-U.S. Employee Benefit Plans will be made on or before the Closing
     Date.

     4.17 Insurance. Schedule 4.17 contains a list of all material insurance
policies maintained by or on behalf of or covering each Seller in connection
with the Business (the "Policies"). Each Seller has made available to Buyer
copies of all current declaration sheets relating to the Policies. Except as
noted on Schedule 4.17, as of the date of the Agreement, the Policies are, to
Sellers' Knowledge, in full force and effect, no notices of cancellation or
nonrenewal have been received by any Seller with respect thereto, and all
premiums due thereon have been paid.

     4.18 Powers of Attorney. Except as set forth on Schedule 4.18, none of
the Sellers has given any irrevocable power of attorney (other than such powers
of attorney given in the Ordinary Course of business with respect to routine
matters or as may be necessary or desirable in connection with the consummation
of the Contemplated Transactions) to any person, firm, or corporation for any
purpose whatsoever with respect to the Business.

     4.19 Brokers. With the exception of fees and expenses payable to Raymond
James & Associates, Inc. and Jefferies & Co., Inc., which shall be paid by
Kaiser, all negotiations relating to this Master Agreement, and the Contemplated
Transactions, have been carried on without the participation of any Person
acting on behalf of any Seller or such party's Affiliates in such manner as to
give rise to any valid claim against Buyer for any brokerage or finder's

                                    - 11 -
<PAGE>

commission, fee or similar compensation, or for any bonus payable to any
officer, director, employee, agent or sales representative of or consulant to
any Seller or such party's Affiliates upon consummation of the Contemplated
Transactions.

     4.20 Taxes. Except as set forth on Schedule 4.20, with respect to Taxes:

                 (a)  Each Seller has properly completed and filed or caused to
     be filed or shall properly complete and file or cause to be filed, within
     the time prescribed by law, including extensions, all Tax Returns with
     respect to the Transferred Assets or Transferred Subsidiaries that are or
     were required to be filed under federal, state, local or any foreign laws
     prior to the Closing Date, except where the failure to file such Tax
     Returns would not have a Material Adverse Effect on the Business.

                 (b)  Each Transferred Subsidiary has, within the time and in
     the manner prescribed by law, paid or caused to be paid (and until the
     Closing will, within the time and in the manner prescribed by law, pay or
     cause to be paid) all Taxes due and payable prior to the Closing, except
     where the failure to pay such Taxes would not have a Material Adverse
     Effect on the Business.

                 (c)  No extensions or waivers of statutes of limitation with
     respect to any Tax Returns of any Transferred Subsidiary (or its parent if
     filing a consolidated or combined Tax Return) have been given by or
     requested from any of the Transferred Subsidiaries (or such parent).

                 (d)  None of the Transferred Subsidiaries, or any entity in
     which a Transferred Subsidiary owns an interest, is a party to or bound by
     any tax indemnity, tax sharing or tax allocation agreement that will not be
     terminated on the Closing Date.

     4.21  Accounts Receivable. The accounts receivable of the Business
reflected on the Financial Statements, are valid and existing receivables which
arose in the Ordinary Course and are collectible substantially in accordance
with their terms and at their recorded amounts, subject to a reserve for bad
debts as will be set forth in the Closing Financial Statements.

     4.22  Adequacy of Assets. Except as set forth on Schedule 4.22, the
Transferred Assets and the services to be provided pursuant to the terms of the
Transition Services Agreement are sufficient for the conduct of the Business on
the Closing Date in substantially the same manner in which it has been conducted
by Sellers since March 31, 2000.

                                   ARTICLE 5

                    REPRESENTATIONS AND WARRANTIES OF BUYER

     Buyer represents and warrants to Kaiser as set forth below as of the date
of this Master Agreement:

                                     -20-
<PAGE>

     5.1  Organization and Standing of Buyer. Buyer 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 enter into this Master Agreement and the Ancillary Agreements, to
carry out the Contemplated Transactions and to perform its obligations
hereunder. Buyer is a domestic corporation within the meaning of Section 7701 of
the Tax Code.

     5.2  Authorization. The execution, delivery and performance of this Master
Agreement and the Ancillary Agreements executed or to be executed by Buyer
pursuant to this Master Agreement, and the consummation of the Contemplated
Transactions have been duly authorized by all necessary corporate and other
action on the part of Buyer. This Master Agreement and the Ancillary Agreements
executed or to be executed by Buyer 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 Buyer.

     5.3  Enforceability. This Master Agreement and each Ancillary Agreement
constitutes, or when executed and delivered will constitute, the valid and
legally binding obligation of Buyer, 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.

     5.4  Compliance with Other Instruments and Laws. The execution, delivery
and performance of this Master Agreement and the Ancillary Agreements executed
or to be executed by Buyer pursuant to this Master Agreement, and the
consummation of the Contemplated Transactions will not conflict with or result

of Buyer, or (b) 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 Buyer or any of its properties or assets, 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 operations or financial
condition of Buyer and its subsidiaries, taken as a whole, or would materially
impair Buyer's ability to consummate the Contemplated Transactions (a "Material
Adverse Effect on Buyer").

     5.5  Governmental Authorizations and Consents. Except as set forth on
Schedule 5.5, no consents, licenses, approvals or authorizations of, or
registrations or declarations with, any Governmental Authority, bureau, agency
or commission, or any third party, are required to be obtained or made by Buyer
in connection with the execution, delivery, performance, validity and
enforceability of this Master Agreement or the other Ancillary Agreements, other
than (a) Bankruptcy Court approval, and (b) other consents, licenses, approvals,
authorizations, registrations or declarations, where the failure to obtain such
would not have a Material Adverse Effect on Buyer. Buyer is not currently
engaged in, or contemplating, any business transaction that would be reasonably
expected to hinder or delay the authorizations and consents referred to in this
Section 5.5.

     5.6  Litigation. As of the date of this Master Agreement, no action, suit,
proceeding or governmental investigation is pending or, to the knowledge of
Buyer, threatened, against

                                     -21-

Buyer or its properties, at law or in equity or before any Governmental
Authority that seeks to question, delay or prevent the consummation of the
Contemplated Transactions.

     5.7  Access. Buyer has received and reviewed the Financial Statements and
is acquainted with the Business. Buyer has had an opportunity to review the
assets, books, records and contracts of the Business made available to it by

information regarding the Business operations and its financial and legal
affairs.

     5.8  Financial Capacity. Buyer has the financial capacity to consummate the
Contemplated Transactions within its existing credit lines as previously
disclosed to Kaiser.

     5.9  Brokers. No agent, broker, Person or firm acting on behalf of Buyer or

finder's fees from any of the parties hereto, or from any Person controlling,
controlled by or under common control with any of the parties hereto, in
connection with any of the Contemplated Transactions.

     5.10 Buyer Awareness. As of the date of this Master Agreement, Buyer is not
aware of any fact, circumstance or condition which Buyer believes constitutes a
material breach of any representation or warranty of Kaiser contained in this
Master Agreement, or which could reasonably be expected to have a Material
Adverse Effect on the Business.

                                   ARTICLE 6

                  COVENANTS RELATING TO PERSONNEL ARRANGEMENTS

     6.1  Transferee Employees. Effective as of the Closing Date, Sellers shall
terminate the employment of the Employees of the Business (including persons
hired following the execution and delivery of this Master Agreement pursuant to
Section 7.1), other than the employees of the Transferred Subsidiaries, and
Buyer or one of its Subsidiaries shall offer employment to all employees whose
employment is so terminated effective as of the time of their termination of
employment with Sellers, including all employees who are not actively at work on
the Closing Date due to short-term disability, layoff, military service or other
authorized leave of absence. In addition, Buyer shall offer employment to all
Employees of the Business who on the Closing Date are absent from work due to a
long-term disability and who notify Buyer within twelve months of the Closing
Date that they have recovered from such long-term disability. All such employees
who accept Buyer's offer of employment and all employees of Transferred
Subsidiaries shall be referred to herein as "Transferee Employees." Buyer or its
Subsidiaries shall hire Transferee Employees other than employees covered by a
collective bargaining agreement at levels of direct cash compensation (excluding
employee and fringe benefits) not lower than their current level of direct cash
compensation with Sellers. Except as otherwise provided herein, Sellers shall be
responsible for (by payment or accrual on the Closing Financial Statements)
wages, salaries and benefits (including vacations) of employees until they
become Transferee Employees.

                                     -22-
<PAGE>

     6.2  Severance Obligations. 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
as required in Section 6.1 shall receive severance and accrued vacation
benefits, if any, under the Welfare Plan, Benefit Arrangements and Retention
Arrangements of Sellers, and Buyer shall reimburse Sellers for the payment of
any such amounts which may be due. Notwithstanding anything contained in the
prior sentence to the contrary, Buyer shall have no such payment obligations to
any Employee of the Business who is in good faith offered employment by Buyer
and does not accept such employment, and Sellers will be solely responsible for
obligations, if any, for such benefits, including Retention Arrangements, for
any Employees of the Business who for any reason do not become Transferee
Employees after receiving a good faith offer of employment from Buyer. Buyer
shall be solely responsible for the payment of Retention Arrangements to the
extent reflected on the Closing Financial Statements. Sellers shall be solely
responsible for any obligation for severance pay for Employees of the Business
who become Transferee Employees, including severance pay to any Transferee
Employee who asserts that either the termination of employment by a Seller and
subsequent employment by Buyer or one of its subsidiaries or the transfer of
ownership of a Transferred Subsidiary to Buyer constitutes a termination of
employment which entitles him to severance pay. In the case of any Transferee
Employee whose employment is based in the United States and is terminated by
Buyer, Buyer will make severance payments in accordance with Buyer's severance
policies. Buyer acknowledges that it has not informed Sellers of any planned or
contemplated decisions or actions by Buyer or one of its subsidiaries that would
require service of notice under the WARN Act. Buyer agrees that neither it nor
any of its subsidiaries will take any action which will cause the notice
provision of the WARN Act to become applicable to the Contemplated Transactions.

     6.3  COBRA Obligations. Buyer will be solely responsible for any
obligations for continuation coverage under Section 4980B of the Tax Code and
part 6 of Subtitle B of Title I of ERISA with respect to Transferee Employees.

     6.4  Plans, Benefits and Policies.

          (a) Except as otherwise provided herein, Buyer and its Subsidiaries
     will, as of the Closing Date, adopt and provide for Transferee Employees
     whose employment is based in the United States employment and benefit plans
     and programs (including, to the extent applicable, profit sharing and
     retirement plans, medical and severance benefits) on terms and conditions
     consistent with Buyer's employment and benefit plans and programs
     maintained for similarly situated employees of Buyer.

          (b) Buyer and its Subsidiaries will credit Transferee Employees with
     service with Sellers (and predecessors of Sellers) for purposes of (i)
     vesting for and eligibility to participate in any Pension Plan, but not for
     purposes of benefit accruals; (ii) any waiting periods, eligibility or pre-
     existing condition limitations for any Welfare Plan; and (iii) eligibility
     and benefit computation for vacation and severance pay plans; provided,
                                                                   --------
     however, that with respect to vacation plans for the remainder of calendar
     -------
     year 2000 only, Buyer shall maintain vacation plans equivalent to, and in
     lieu of, Sellers' vacation plans covering the Transferee Employees
     immediately prior to the Closing Date (offset by vacation time used under
     Sellers' vacation plans as of the Closing Date).  Buyer shall

                                     -23-
<PAGE>

     credit Transferee Employees with any amounts paid prior to the Closing Date
     under any Welfare Plan that is a health plan toward the satisfaction of
     deductible amounts and copayment minimums under the Buyer's corresponding
     welfare benefit plans.

          (c) Sellers shall take all necessary actions to vest all Transferee
     Employees in their benefits under any Pension Plan maintained by a Seller
     (other than the Transferred Subsidiaries) as of the Closing Date.  Sellers
     have not made contributions to their Pension Plans with respect to the
     years 1999 and 2000.

          (d) Sellers 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 Seller as of the Closing Date.

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

          (f) Except as otherwise provided herein, as of the Closing Date all
     Transferee Employees whose employment is based in the United States shall
     cease participation in Benefit Plans of Sellers.

          (g) Sellers and/or the applicable U.S. Benefit Plans or other employee
     benefit programs sponsored or administered by Sellers shall be responsible
     for benefits accrued or claims incurred prior to the Closing (including
     expenses incurred post-Closing on a claim incurred prior to Closing) with
     respect to Transferee Employees and their eligible dependents in accordance
     with the provisions of the applicable Seller's employee benefit program
     with respect to:  (i) disability benefits, both long-term and short-term,
     for disabilities that commenced before the Closing Date; (ii) benefits for
     confinements covered under Seller's medical plans that commenced before the
     Closing Date; (iii) health care benefits for services rendered or materials
     received under Seller's medical plans before the Closing Date; and (iv)
     worker's compensation benefits for disabilities resulting from an accident
     or occurrence while employed by Seller or a Subsidiary of Seller or a
     predecessor thereof which occurred prior to the Closing Date.

          (h) After Closing, Buyer and Sellers will cooperate with each other
     and provide each other such information as is required concerning
     Transferee Employees in order to determine whether a Transferee Employee is
     entitled to compensation from either party or benefits under any plan,
     program or arrangement sponsored or maintained by either party.

          (i) No provision in this Article 6 or Section 2.3(d) shall create any
     third-party beneficiary rights in any employee or former employee
     (including any beneficiary or dependent thereof) of Buyer, Kaiser, any
     Seller or any of their Affiliates.

                                     -24-
<PAGE>

     6.5  Foreign Employees. As of the Closing Date, Buyer shall cause the
Transferred Subsidiaries to continue to provide the Non-U.S. Employee Benefit
Plans for Transferee Employees whose employment is based outside the U.S.,
subject to the right of Buyer and its Subsidiaries to amend or terminate such
benefit plans on a basis consistent with the terms and conditions of Buyer's
employment and benefit plans from time to time.

     6.6  Bonuses. Sellers and Buyer agree that U.S. based Employees of the
Business who become Transferee Employees shall participate in Buyer's applicable
bonus programs as of the Closing Date. Buyer shall be liable for bonuses
accruing prior to the Closing Date to the extent of the aggregate accrual amount
identified on the Closing Financial Statements. Kaiser shall schedule such bonus
accrual on the Closing Financial Statements, identifying each employee entitled
to a bonus and the bonus accrual for such employee.

                                   ARTICLE 7

                             COVENANTS OF SELLERS

     7.1  Conduct of Business.

          (a) Except as set forth on Schedule 7.1 or as may be otherwise
     expressly permitted by this Master Agreement or with the prior written
     consent of Buyer, and subject to any order of the Bankruptcy Court which
     shall take precedence over any provision of this Master Agreement, from the
     date hereof and prior to the Closing, Kaiser will, and will cause each
     Seller to: (i) operate the Business only in the Ordinary Course; (ii) use
     commercially reasonable 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 commercially reasonable efforts to preserve each Seller's relationships
     with its suppliers, customers, licensors and licensees and others having
     business dealings with any Seller relating to the Business.

          (b) Without limiting the generality of Section 7.1(a), and except as
     may be otherwise expressly permitted by this Master Agreement or ordered by
     the Bankruptcy Court or with the prior written consent of Buyer, which
     shall not be unreasonably withheld, delayed or conditioned, from the date
     hereof through the Closing, Kaiser shall not permit any Seller, with
     respect to the Business, to:

              (i)   enter into any material transaction in connection with the
          Business outside the Ordinary Course.

              (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 Master Agreement;

              (iii) sell, lease, transfer, mortgage or assign any of the
          Transferred Assets, tangible or intangible, other than in the Ordinary
          Course;

                                     -25-
<PAGE>

              (iv)   cancel, compromise, knowingly waive or lease any material
          right or claim (or series of related rights and claims) under Material
          Contracts, outside the Ordinary Course;

              (v)    make any change in the rate of compensation, commission,
          bonus or other direct or indirect remuneration payable, or agree to
          pay, conditionally or otherwise, any material bonus, incentive,
          retention or other compensation, retirement, welfare, fringe or
          severance benefit or vacation pay, to or in respect of any Employee of
          the Business, other than the increases and payments in the Ordinary
          Course in compensation payable to Employees of the Business and any
          Retention Arrangements;

              (vi)   except for the elimination of intercompany transactions
          contemplated by this Master Agreement, cause or permit any Transferred
          Subsidiary to declare, pay or distribute any dividend, bonus or other
          distribution of profits, or any return or distribution of capital, to
          its shareholders and will return or caused to be returned any such
          payment or distribution to such Transferred Subsidiary;

              (vii)  terminate any Employee of the Business whose annual cash
          compensation exceeds U.S. $75,000;

              (viii) induce any of the Employees of the Business to leave the
          employ of Sellers;

              (ix)   hire any Employee of the Business with annual cash
          compensation exceeding U.S. $75,000; and

              (x)    agree to do any of the foregoing.

          (c) In the event that any of Sellers wishes to engage in any act which
     falls within the provisions of Section 7.1(b), such Seller shall provide
     notice thereof to Buyer who shall advise such Seller within three business
     days of any objection Buyer has with such action.  In the event that Buyer
     fails to object within such period, Buyer shall be deemed to have waived
     any objection to such act.

          (d) Notwithstanding anything to the contrary contained herein, (i) at
     any time prior to the Closing, Sellers may cause any asset of a Transferred
     Subsidiary that would not be included in the Transferred Assets if the
     assets, rather than the stock, of such Transferred Subsidiary were being
     conveyed hereunder, to be transferred to Kaiser or one or more of its
     Subsidiaries, and (ii) prior to the Closing, Kaiser shall remove from the
     books of each Transferred Subsidiary any intercompany receivable or
     intercompany payable, so that at and after the Closing no Transferred
     Subsidiary shall owe, or have the right to receive from, Kaiser or any of
     its other Subsidiaries (other than a Transferred Subsidiary) any amount for
     goods, services or cash advanced or other extensions of credit provided
     prior to the Closing.  Sellers shall not remove any asset from a
     Transferred Subsidiary which is reflected on the Closing Financial
     Statements.  If an Australian

                                     -26-
<PAGE>

     Transferred Subsidiary has a Subsidiary incorporated in the Philippines,
     then on or before Closing Kaiser shall cause the Australian Transferred
     Subsidiary to transfer all of the capital stock of that Filipino Subsidiary
     owned beneficially and of record by that Australian Transferred Subsidiary
     to Kaiser or a Kaiser Subsidiary which is not a Transferred Subsidiary.

          (e)  Between the ending date of the Closing Financial Statements and
     the Closing, Kaiser (i) shall apply cash received in payment of accounts
     receivable of the Business to the payment of Liabilities of the Business in
     the Ordinary Course of the Business consistent with prior periods in types
     and amounts and (ii) shall not engage in any intercompany transaction which
     is prohibited by Section 7.1.

          7.2  Use of Business Names by Buyer.

          (a)  Buyer acknowledges that Sellers have asserted the absolute and
     exclusive proprietary right to all names, marks, trade names, trademarks,
     service names and service marks (collectively, "Names") incorporating
     "Kaiser" or "Kaiser Engineers" or any similar Name and to all corporate
     symbols or logos (collectively, "Logos") incorporating "Kaiser" or "Kaiser
     Engineers" or any similar Name.  All rights of Sellers and its Affiliates
     to the same and the goodwill represented thereby and pertaining thereto are
     being retained by Sellers.  Buyer agrees that it will not, and will cause
     the Business not to, use the Kaiser or Kaiser Engineers 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 7.2.

          (b)  Buyer shall not use in any manner the Kaiser and Kaiser Engineers
     Names and the Kaiser and Kaiser Engineers Logos incorporating such Names
     except to the extent provided pursuant to the Kaiser Trademark License
     Agreement.  At all times following the Closing, Buyer shall not indicate
     that Buyer or the Business is affiliated with any Seller or any of its
     Affiliates.

                                     -27-
<PAGE>

         7.3  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 Seller
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 Seller 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
Seller shall use its commercially reasonable 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 7.3 as confidential in
compliance with Section 9.10.

         7.4  Acquisition Proposals. Kaiser specifically agrees that neither
Sellers nor any representative acting on their behalf nor any Affiliate of
Kaiser shall solicit any offer from any third party with respect to the
disposition of all or a substantial part of the assets of the Business unless
required by the Bankruptcy Court or unless Kaiser receives an opinion from
nationally recognized bankruptcy counsel to the effect that Kaiser and Sellers
have a fiduciary duty to take such action.

                                   ARTICLE 8

                              COVENANTS OF BUYER

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

         8.2  Intentionally Omitted.

         8.3  Buyer Cooperation.

              (a)   Buyer shall, and shall cause its Affiliates to, provide
     transition support to Kaiser's Nova Hut project, primarily from Pittsburgh,
     on arms' length terms as provided for in the Transition Services Agreement,
     and meet, at their own expense, with interested parties, including without
     limitation Nova Hut a.s. and the International Finance Corporation to
     confirm this support. In consideration of this support, Buyer and Kaiser
     will split, or cause to be split, the fees, if any, payable to Kaiser
     Netherlands, B.V., its successors or assigns upon final acceptance of the
     Nova Hut project, with an amount equal to 20% of the "net fee" (e.g., net
     of payment to project employees) payable to Buyer and 80% being retained by
     Kaiser Netherlands, B.V., its successors or assigns. Notwithstanding
     anything herein to the contrary, Kaiser will retain the right to decide, in

                                     -28-
<PAGE>

     its sole discretion, to negotiate changes to, and cease performing on, the
     Nova Hut contract at any time without liability to Buyer or its Affiliates
     (other than as provided in the Transition Services Agreement). For the
     avoidance of doubt, this provision only relates to the division of the
     success fees and does not relate to the cash collateral or retentions.
     Kaiser will cause any transferee of the capital stock of Kaiser
     Netherlands, B.V. to assume Kaiser's obligations under this Section 8.3(a).

          (b)  (i)  With respect to the Worsley project in Australia, following
     the payment of any fees (A) due to Kaiser's Australian Transferred
     Subsidiaries in connection with the Worsley project reflected as
     receivables in the Closing Financial Statements and (B) for ongoing
     services provided by Kaiser's Australian Transferred Subsidiaries in
     connection with the completion of the Worsley project, Buyer will pay to
     Kaiser an amount equal to 70% of the net amount of disputed fees (net of
     direct costs expended in connection with the pursuit of such fees), if any,
     received by Kaiser Engineers Pty. Ltd. (or its successors and assigns) on
     or after the Closing Date.  For the avoidance of doubt, following the
     Closing neither Kaiser nor any of its Subsidiaries immediately following
     the Closing shall bear any downside risk with respect to the Worsley
     project.

               (ii)(A) Following the Closing Date, Buyer will cause Kaiser
     Engineers Pty Ltd., its successors and assigns to consult with Kaiser on a
     regular basis concerning such disputed fees.

               (B)     In the event that Buyer considers that a resolution with
     respect to such disputed fees may be achievable, Buyer shall use its
     commercially reasonable efforts to cause Kaiser to receive information and
     updates with a view to establishing with Kaiser an approved range of
     settlement options and obtaining the consent of Kaiser thereto.

               (C)     In the event that Kaiser is unwilling or unable to
     consent to settlement options or to a settlement or resolution with respect
     to such fees which is satisfactory to Buyer, Buyer may proceed to settle or
     resolve the matter provided that Buyer does not receive any consideration
     or other financial benefit as a result of such settlement or resolution
     other than its portion of the payment on account of the disputed fees and a
     release of claims arising out of the Worsley project. In the event that a
     proposed resolution includes any other consideration or financial benefit,
     full details thereof shall be provided to Kaiser, and Buyer shall not enter
     into any such resolution without the consent of Kaiser, which consent shall
     not be unreasonably withheld, delayed or conditioned, it being not
     unreasonable for Kaiser to require Buyer to account for and pay to Kaiser,
     Kaiser's 70% share of all such consideration or benefits.

               (D)     In the event that Kaiser does not consent, then the
     parties agree to submit their dispute to an independent arbitrator to be
     selected in accordance with the rules of the American Arbitration
     Association, and the arbitration shall occur in New York City. For the
     avoidance of doubt, the provisions in Sections 9.4 and 9.12 of this Master
     Agreement which survive the Closing will apply to the arbitration. The
     losing party shall pay all reasonable costs and expenses of the
     arbitration.

                           COVENANTS OF BOTH PARTIES

     9.1  Commercially Reasonable Efforts. Subject to the terms and conditions
of this Master Agreement, each party will use its commercially reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary or desirable under Applicable Law and the terms of
this Master Agreement to consummate the Contemplated Transactions, including the
execution and delivery of any further instruments or documents which are
reasonably requested by a party or its counsel to any party signatory hereto in
order to evidence or facilitate the consummation of the Contemplated
Transactions.

     9.2  Other Filings. Buyer and Sellers shall cooperate with one another (i)
in determining whether any other action by or in respect of, or filing with, any
Governmental Authority is required, or any actions, consents, approvals or
waivers are required to be obtained from parties to any Material Contracts, in
connection with the consummation of the Contemplated Transactions and (ii) in
taking such actions or making any such filings, in furnishing such information
as may be required in connection therewith, and in seeking timely to obtain any
such actions, consents, approvals or waivers.

     9.3  Public Announcements. None of Buyer, the Sellers nor any of their
Affiliates will issue any press release or make any public statement with
respect to this Master Agreement or the Contemplated Transactions, or disclose
the existence of this Master 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 public statement without the prior consent of the other party (which
consent shall not be unreasonably withheld or delayed), subject to any
applicable disclosure obligations pursuant to Applicable Law (including Kaiser's
and Buyer's requirement to issue a press release promptly after the execution of
this Master Agreement, Kaiser's obligation to file a Form 8-K with the U.S.
Securities and Exchange Commission, and disclosures required in connection with
the Bankruptcy Case), provided that the party proposing to issue any press
release or similar public announcement or communication in compliance with any
such disclosure obligations shall use commercially reasonable efforts to consult
in good faith with the other party before doing so. In addition, Sellers may
inform their employees of the Contemplated Transactions, and Sellers may
continue to communicate with persons potentially interested in acquiring all or
part of the Business.

     9.4  Consents; Cooperation. Kaiser and Buyer will use their commercially
reasonable efforts, and Kaiser will cause the other Sellers to use their
commercially reasonable efforts:

          (a)  to obtain prior to the earlier of the date required (if so
     required) or the Closing Date, all authorizations, consents, orders,
     permits or approvals of, or notices to, or filings, registrations or
     qualifications with, all Governmental Authorities (including, without
     limitation, the approval of the Bankruptcy Court) and any other Person or
     entity

                                     -30-
<PAGE>

     that are required on their respective parts, for the consummation of the
     Contemplated Transactions;

          (b)  to defend, consistent with applicable principles and requirements
     of law, any lawsuit or other legal proceeding, whether judicial or
     administrative, whether brought derivatively or on behalf of third Persons
     (including Governmental Authorities) challenging this Master Agreement or
     the Contemplated Transactions;

          (c)  to furnish to each other such information and assistance as may
     reasonably be requested in connection with the foregoing, including without
     limitation, the negotiation of the final versions of the Ancillary
     Agreements;

          (d)  to reasonably assist each other as necessary with regard to the
     determination of contract or order closeouts or other issues which affect
     the Assumed Contracts, to notify Buyer of additional disallowances or
     potential adverse audit findings, and to consult and reach agreement with
     respect to advanced coordination of negotiating positions, offers of
     compromise, or final agreements or settlements, all such cooperation to be
     without charge to both parties to this Master Agreement; and

          (e)  to enter into mutually acceptable arrangements pursuant to which
     any payments recovered by Sellers following the Closing Date in respect of
     receivables arising under the Assumed Contracts following the Closing Date
     are promptly remitted to Buyer.

     9.5  Communications with Customers and Suppliers. Kaiser and Buyer will
     mutually agree upon all communications with suppliers and customers of the
     Business relating to this Master Agreement and the Contemplated
     Transactions prior to the Closing Date.

     9.6  Liability for Transfer Taxes.

          (a)  Buyer shall be responsible for and pay in a timely manner all
     sales, use, value added, documentary, stamp, gross receipts, registration,
     transfer, conveyance, excise, recording, license and other similar Taxes
     and fees (including without limitation any goods and services tax, but, for
     the avoidance of doubt, exclusive of any Income Taxes) ("Transfer Taxes")
     arising out of or in connection with or attributable to the Contemplated
     Transactions.  Each party hereto shall prepare and timely file all Tax
     Returns required to be filed in respect of Transfer Taxes that are the
     primary responsibility of such party under Applicable Law, provided,
                                                                --------
     however, that such party's preparation of any such Tax Returns shall be
     -------
     subject to the other party's approval which approval shall not be
     unreasonably withheld, conditioned or delayed.  Notwithstanding anything to
     the contrary herein, Buyer shall not be responsible for the payment of any
     Transfer Taxes to the extent an order of the Bankruptcy Court rules that
     there is an exemption therefrom under Section 1146(c) of the Bankruptcy
     Code.

          (b)  The Transferred Assets are composed of (i) assets as to which the
     "isolated, casual or occasional sale" exemption or similar exemption from
     Transfer Taxes is or may be applicable and (ii) other assets as to which
     other exemptions from Transfer

                                     -31-
<PAGE>

     Taxes are or may be applicable. In order to obtain any exemption or
     favorable tax rate, Buyer shall, to the extent consistent with Applicable
     Law, provide Sellers with any exemption or resale certificate, permit,
     license or such other documentation as may be required by any taxing
     authority to establish the right to such exemption or tax rate.

     9.7  Books and Records. Subject to the confidentiality provisions hereof,
Kaiser shall have the right to retain copies of the Books and Records. From and
after the Closing and until the sixth anniversary thereof, (a) each Seller
agrees to grant to Buyer, upon reasonable notice and during normal business
hours, reasonable access to any books and records that pertain to the Business,
but which are not Books and Records, to the extent it is operating and has books
and records in its possession, and Buyer may make copies, at Buyer's expense,
and (b) Buyer agrees to grant to Kaiser or its estate, upon reasonable notice
and during normal business hours, reasonable access to any Books and Records
included in the Transferred Assets that pertain to the operations of the
Business on or prior to the Closing Date. Each of Sellers shall provide Buyer
not less than 45 days' notice prior to the destruction of any books and records
that pertain to the Business or the date when it intends to terminate operations
and Buyer shall have the right to have such records copied, at its cost, prior
to destruction.

     9.8  Tax Matters.

          9.8.1  Tax Returns.

          (a)    Kaiser shall be the sole and exclusive agent of the Transferred
     Subsidiaries in any and all matters relating to the U.S. federal income tax
     liability of the consolidated group of which Kaiser is the common parent
     (the "Seller Consolidated Group") for all consolidated return years.
     Kaiser shall, inter alia, have the right with respect to any federal
     consolidated returns which it 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 Consolidated
     Group may be entitled, shall be paid by way of refund or credited against
     the tax liability of Seller Consolidated Group.  Prior to the Closing,
     Kaiser will cause the Transferred Subsidiaries to irrevocably appoint
     Kaiser as agent and attorney-in-fact to take such action (including the
     execution of documents) as Kaiser may deem appropriate to effect the
     foregoing.

          (b)    Kaiser shall file or cause to be filed when due all Tax Returns
     in respect of Taxes not related to the Transferred Subsidiaries for taxable
     years or periods ending on or before the Closing Date and shall pay or
     cause to be paid the Taxes shown to be due on any such Return.

          (c)    Buyer shall be responsible for filing all Tax Returns relating
     to the Transferred Subsidiaries following the Closing Date, whether or not
     they relate to taxable years or periods ending on or prior to the Closing
     Date.

                                     -32-
<PAGE>

          (d)   Buyer shall file or cause to be filed when due all Tax Returns
     in respect of Taxes not related to the Transferred Subsidiaries for taxable
     years or periods ending after the Closing Date and shall pay or cause to be
     paid the Taxes shown to be due on any such Tax Return.

          (e)   Buyer shall have the sole right, at its sole expense and for its
     sole benefit, 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 before, on or after the Closing Date.

     9.8.2  Tax Liability. Whenever it is necessary for purposes of this Master
Agreement to determine the Tax Liability of the Transferred Subsidiaries or
Taxes related to the Business for a taxable year or period that ends on or 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 day prior to the Closing Date
and by using the accounting practices and procedures previously used by Kaiser
or the Transferred Subsidiaries, as the case may be, in preparing its Tax
Returns, provided that (a) exemptions, allowances or deductions that are
         --------
calculated on an annual basis, such as the deduction for depreciation, shall be
apportioned on a time basis, (b) Taxes (other than income taxes) that are
determined based upon specific transactions (including but not limited to value
added, sales, and use Taxes) shall be allocated in accordance with the timing of
such specific transactions, and (c) responsibility for real estate, personal
property, license, franchise, doing business, and similar Taxes (but not
including any Taxes based on income) shall be pro rated as of the Closing Date
based on the fiscal tax year to which such Taxes relate as set forth on the day
prior to the Closing Financial Statements.

            9.8.3  Cooperation.

            (a)    Kaiser 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 procedure relating
     to Taxes, or (iii) any other matter that is the subject of this Master
     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
     procedure relating to Taxes, 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.

                                     -33-
<PAGE>

          (b)   Kaiser 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).  After the expiration of the time when the Tax
     Data and the Tax Documentation must be retained pursuant to this Section
     9.8.3(b), then any such material may be destroyed.  Kaiser shall give Buyer
     not less than thirty (30) days prior written notice before Tax Data or Tax
     Documentation in the possession or control of any member of the Seller
     Consolidated Group is destroyed and shall give Buyer an opportunity to copy
     any such material during such thirty (30) day period.  Buyer shall give
     Kaiser not less than thirty (30) days prior written notice before any Tax
     Data or Tax Documentation in the possession or control of Buyer or any
     Transferred Subsidiary is destroyed and shall give Kaiser an opportunity to
     copy any such material during such thirty (30) day period.

     9.9  Tax Elections. Kaiser shall make no material new elections with
respect to Taxes, or any material changes in current elections with respect to
Taxes, affecting the Transferred Assets or the Transferred Subsidiaries for
periods from and after the Closing Date after the date of this Master Agreement
without the prior written consent of Buyer.

     9.10 Confidentiality.

          (a)  Between the date of this Master Agreement and the Closing Date,
     Buyer and Sellers will maintain in confidence, and will cause their
     respective directors, officers, employees, agents and advisors to maintain
     in confidence, and not use to the detriment of another party, Sellers or
     the Transferred Subsidiaries any written, oral, or other information
     obtained in confidence from another party, Sellers  or the Transferred
     Subsidiaries in connection with this Master Agreement or the Contemplated
     Transactions, unless (i) such information is already known to such party or
     to others not bound by a duty of confidentiality or such information
     becomes publicly available through no fault of such party, (ii) the use of
     such information is necessary or appropriate in making any filing or
     obtaining any consent or approval required for the consummation of the
     Contemplated Transactions, or (iii) the furnishing or use of such
     information is required by legal proceedings; provided, however, that the
                                                   --------  -------
     party required to disclose the confidential information pursuant to Section
     9.10(a)(iii) shall first notify the other party of such order and afford
     the other party the opportunity to seek a protective order relating to such
     disclosure.

          (b)   If the Contemplated Transactions are not consummated, each party
     will immediately return or destroy all such confidential information and
     any and all copies

                                     -34-
<PAGE>

     thereof, however stored, and, if requested by the other
     party, shall certify conformity with this Section 9.10(b) in writing.

           (c)   Following the Closing, Sellers shall not, and shall cause their
     officers, directors, employees and agents not to, disclose any confidential
     information specific to the Business to any third party, except as required
     under the Transition Services Agreement.

     9.11  Ancillary Agreements. Following the Closing Date, Kaiser and Buyer
will perform, or cause to be performed, their respective obligations under the
Ancillary Agreements.

     9.12  Assistance. Following the Closing Date, upon request of any party,
the other party will use its commercially reasonable efforts to assist such
party in connection with collection of accounts receivable related to the
Transferred Assets or the Excluded Assets as the case may be. To the extent a
party receives payments that belong to the other party, such party shall
promptly pay such amounts to the appropriate party. Neither party shall
compromise any accounts receivable or other payments due to the other party
without the prior written consent of the other party.

     9.13  Notice. Between the date of this Agreement and Closing, Buyer and
Sellers shall promptly notify the other party of any fact, circumstance or

                 BUYER PROTECTIONS: OVERBIDDING PROCEDURES AND
                                 BREAK-UP FEES

     10.1  Bankruptcy Court Approvals. As promptly as practicable, Sellers
subject to Bankruptcy Court approval shall file with the Bankruptcy Court and
serve motions seeking: (i) a hearing (the "Interim Hearing") before the
Bankruptcy Court for an order (A) approving, among other things, the adequacy of
notice to creditors and parties in interest of the final hearing to approve the
sale of the Transferred Assets and the assumption of the Assumed Liabilities
(the "Sale Hearing"), and (B) setting a date for the Sale Hearing (the "Interim
Order"); and (ii) an order authorizing, among other things, (A) Sellers to sell
the Transferred Assets to Buyer pursuant to this Master Agreement and Sections
363 and 365 of the Bankruptcy Code, free and clear of all encumbrances
(including without limitation any and all "interests" in the Transferred Assets
within the meaning of Bankruptcy Code Section 363(f), except for the Assumed
Liabilities, and (B) Buyer to assume the Assumed Liabilities and Sellers to be
relieved of liability therefrom (the "Sale Order").

                                     -35-
<PAGE>

     10.2  Obtaining the Orders. Sellers shall use their commercially reasonable
efforts to obtain the Interim Order and the Sale Order as soon as practicable.
The Interim Order and the Sale Order shall be in form and substance reasonably
satisfactory to the Buyer.

     10.3  Overbidding Procedures and Break-Up Fee. Sellers and Buyer agree that
the overbidding procedures allowing for the payment of a Break-Up Fee shall be
as follows:

           (a)  No competing bid will be accepted or approved by the Sellers
     unless it is made pursuant to terms substantially similar to those
     contained in this Master Agreement (a "Competing Bid") and provides for
     aggregate consideration having a value equal to at least the sum of (A) the
     Purchase Price plus (B) the Break-up Fee, if any is required to be paid on
     account of the Competing Bid, plus (C) One Hundred Thousand Dollars
     ($100,000);

           (b)  Any bidder making a Competing Bid (a "Competing Bidder") shall
     be required to deliver to the Sellers an executed copy of an agreement
     substantially similar to this Master Agreement (the "Competing Bid
     Agreement") on or before three (3) calendar days before the date scheduled
     by the Bankruptcy Court for the Sale Hearing, together with evidence of the
     Competing Bidder's financial ability to consummate the Competing Bid
     Agreement; and the Competing Bidder shall be required to submit to the
     Sellers on or before the date scheduled by the Bankruptcy Court for the
     Sale Hearing, a cashier's check drawn to the order of the Sellers in an
     amount equal to five percent (5%) of the purchase price set forth in the
     Competing Bid (the "Competing Bid Deposit") (or a letter of credit in such
     amount in a form reasonably satisfactory to Kaiser from a commercial bank
     in the United States) . If one or more Competing Bid Agreements are
     submitted, an auction shall be held at the office of the Sellers' counsel,
     222 Delaware Avenue, Suite 1200, Wilmington, DE 19801. At the auction,
     Buyer and all parties who have submitted conforming Competing Bid
     Agreements shall have the opportunity to submit additional higher and
     better bids (each successive Competing Bid Agreement shall be in increments
     of not less than $100,000 in each successive round of bidding). At the Sale
     Hearing, Sellers will determine the highest and best bid and will request
     the Bankruptcy Court to confirm Sellers' determination of the prevailing
     Competing Bidder; if so determined, the prevailing Competing Bidder shall
     execute and deliver at the Sale Hearing, to the extent not delivered
     already, a signed instrument of irrevocable agreement with terms
     substantially similar to those described in this Master Agreement.

           (c)  If the closing under an agreement is not timely concluded with a
     successful Competing Bidder, Sellers shall be authorized without further
     Bankruptcy Court approval or orders promptly to conclude the Contemplated
     Transactions with the next highest willing bidder at the Sale Hearing in
     accordance with the terms of such next highest winning bidder's bid
     (assuming such bid otherwise complies with this Master Agreement).

           (d)  Subject to approval of the Bankruptcy Court and the closing of
     the Contemplated Transactions by an accepted Competing Bid, if a Competing
     Bid is approved by order of the Bankruptcy Court, Buyer shall be paid a
     break-up fee of three percent (3%) of the Purchase Price (the "Break-Up
     Fee"), and shall have its Deposit

                                     -36-
<PAGE>

     refunded; provided, however, notwithstanding anything to the contrary
               --------  -------
     herein, no such Break-Up Fee shall be paid to Buyer if (i) the Buyer has
     terminated, withdrawn or abandoned this Master Agreement for any reason
     other than pursuant to Section 13.1(c)(i) or (ii) Sellers have, prior to
     the issuance of such order of the Bankruptcy Court, terminated this Master
     Agreement pursuant to Section 13.1(c)(ii), except that the Deposit shall be
     returned to Buyer if Buyer terminates this Master Agreement pursuant to
     Section 13.1(c)(i).

           (e)  Subject to Section 10.3(f), the Buyer shall be entitled to
     payment of the Break-Up Fee (and the Deposit) if the Sellers materially
     breach their obligations to proceed with the Contemplated Transactions for
     any reason, and Buyer terminates this Master Agreement pursuant to Section
     13.1(c).

           (f)  Payment of the Break-Up Fee and a refund of the Deposit shall
     (i) be full consideration for Buyer's efforts and expenses in connection
     with the bidding process, this Master Agreement and the Contemplated
     Transactions, including the due diligence efforts of Buyer and its
     professionals and advisors and (ii) constitute liquidated and agreed
     damages in respect of this Master Agreement and the Contemplated
     Transactions, and Sellers shall have no further liability to the Buyer.
     Buyer believes that it is impossible to determine accurately the amount of
     all damages that it would incur by virtue of a breach by Sellers of their
     obligations to proceed with the Contemplated Transactions, and its sole and
     exclusive remedy for any such breach shall be to receive payment of the
     Break-Up Fee (and a refund of the Deposit). Except as provided in this
     Section 10.3 and Section 13.3, Buyer shall have no right nor remedy against
     any Seller, at law or in equity, by reason of a breach by any Seller of its
     obligation to proceed with the Contemplated Transactions.

           (g)  Sellers shall obtain an order from the Bankruptcy Court that
     provides that the Break-Up Fee shall constitute a first priority
     administrative expense of the Sellers pursuant to Section 503(b) of the
     Bankruptcy Code and shall be paid upon the earlier of (i) the closing of
     the Contemplated Transactions by an accepted Competing Bid and (ii) the
     entry of any order of the Bankruptcy Court directing payment by Sellers of
     such amounts.

           (i)  Sellers reserve the right to alter, amend and/or revise the
     bidding procedures as they deem appropriate.

have, performed in all material respects all obligations required by this Master
Agreement to be performed by Kaiser or any Seller on or before the Closing Date,

to be obtained by any Seller in connection with the Contemplated Transactions
that are identified on Schedule 11.7 shall have been obtained and shall be in

Adverse Effect on Buyer (unless such conditions adversely affect Sellers 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 Sellers 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 Sellers
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 Transferred 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 Sellers of any covenant or obligation set forth in this Master
Agreement shall not be taken into account in determining whether there has been

on Buyer, respectively.

warranty to Buyer except as specifically made in this Master Agreement and the

such projections and forecasts so furnished to it, and (d) it shall have no
claim against Sellers with respect thereto.
