                    goods which were performed or sold by Sellers prior to the
                    Closing Date in connection with contracts (other than the
                    Assumed Contracts);

        (f)  any violation, Liability, penalty, cost, damage, fine, order,

     Financial Statements, as updated by the final Closing Date Working Capital

                                   ARTICLE 3

                                  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 fifth 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 (i)
U.S. $ 30,000,000.00 plus (ii) any amounts incurred by Sellers in connection
with severance obligations and retention obligations

                                      -8-
<PAGE>

due to employees terminated by Sellers and not offered employment by Buyer or
Buyer Designee pursuant to Section 6.1 (the "Purchase Price"), less the sum of
(i) any cash Deposit and (ii) the Holdback Amount, by wire transfer of
immediately available funds to an account or accounts designated by Kaiser. The
Purchase Price is subject to adjustment pursuant to Section 3.8.

     3.3  Deposit.   Upon execution of this Master Agreement, Buyer shall pay to
Sellers $900,000 (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 in a form reasonably
satisfactory to Kaiser from a commercial bank in the United States acceptable to
Kaiser and in an amount equal to the Deposit.  At Closing, the Deposit, if paid
in cash, shall be applied to the Purchase Price.

     3.4  Allocation of Purchase Price.

         (a)  The allocation of the Purchase Price to the Transferred Assets and
     post-Closing Tax treatment of the transaction shall be in accordance with
     Section 1060 of the Code and shall be reported on IRS Form 8594. Neither
     party shall assert any position inconsistent therewith at any time after
     the Closing.

         (b)  Within 60 days after the determination of the final Closing Date
     Working Capital Statement in accordance with Section 3.8, 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 may propose to Buyer any changes to such statement.
     Buyer and Kaiser agree to cooperate in determining a mutually acceptable
     allocation of the Purchase Price and will not file inconsistent allocations
     or take inconsistent positions on any Tax Return or in any Taxation
     proceeding or litigation.

     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.

     3.6  Closing Financial Statements.  On the Closing Date, 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 accounting period ended prior to the Closing.  The Closing Financial
Statements shall be prepared in a manner consistent with the Financial
Statements and the terms of this Master Agreement and shall reflect the
Transferred Assets and Assumed Liabilities as of the date reflected thereon.

     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 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

                                      -9-
<PAGE>

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: (i) continue to use commercially reasonable efforts to
obtain any such approval or consent after the Closing until such time as such
consent or approval has been obtained without any material third-party cost to
Buyer; (ii) hold such Consent from a Governmental Authority, instrument,
contract, lease, permit or other agreement or arrangement on behalf of Buyer;
(iii) cooperate with Buyer in any lawful arrangement to provide that Buyer shall
receive the benefits under any such Governmental Approval, instrument, contract,
lease, permit or other agreement or arrangement, including performance by such
Seller, as agent, and (iv) enforce and perform for the account of Buyer any
rights of such Seller arising from such Consent from a Governmental Authority,
instrument, contract, lease, permit or other agreement or arrangement, provided
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.

     3.8  Post-Closing Adjustment.

          (a)  The Purchase Price will be reduced, dollar for dollar, following
     the Closing to the extent that the Working Capital of the Business as of
     the Closing Date (the "Closing Date Working Capital") as identified on the
     final Closing Date Working Capital Statement is less than the difference
     between (i) $5,700,000 minus (ii) any amount paid by Sellers with the
     approval of Buyer in connection with the termination of personal property
     lease obligations (the "Minimum Working Capital"). For purposes of this
     Agreement, the term "Working Capital" shall mean the difference between (i)
     the sum of accounts receivable and other current assets of the Business,
     minus (ii) the sum of current liabilities of the Business. For the
     avoidance of doubt, the parties hereto agree that Transfer Taxes that are
     the subject of Section 9.6 hereof shall be excluded from the computation of
     such adjustment.

         (b)   The Closing Date Working Capital Statement will be prepared by
     Buyer from the books of account of the Business as of the Closing Date. The
     Closing Date Working Capital Statement shall be prepared in accordance with
     GAAP and consistent with the practices of Sellers used in the preparation
     of the Closing Financial Statements. Buyer will deliver the Closing Date
     Working Capital Statement to Sellers not later than 30 days after the
     Closing Date. If Buyer fails to deliver the Closing Date Working Capital
     Statement to Sellers during such 30-day period, then Sellers shall be
     entitled to receive from Buyer, and Buyer shall pay to Sellers, the entire
     Holdback Amount, plus interest as computed pursuant to Section 3.8(e).

         (c)   Buyer will give representatives of Sellers access to the premises
     of the Business, to its books and records and Sellers access to the
     appropriate personnel of Buyer for purposes of confirming the Closing Date
     Working Capital Statement. Unless Sellers notify Buyer in writing that
     there is a disagreement with the Closing Date Working Capital Statement
     within 30 days after receipt thereof, the Closing Date Working Capital
     Statement shall be conclusive and binding on Buyer and Sellers and deemed
     final.

                                     -10-
<PAGE>

         (d)  If Sellers notify Buyer in writing of a disagreement with the
     Closing Date Working Capital Statement within such 30-day period, then
     Buyer and Sellers shall attempt to resolve their differences with respect
     thereto within 10 days after Buyer's receipt of Sellers' written notice of
     disagreement. Any dispute regarding the Closing Date Working Capital
     Statement not resolved by Buyer and Sellers within such 10-day period will
     be resolved by an accounting firm mutually acceptable to both parties or,
     in the absence of agreement, by an accounting firm of national reputation
     selected by lot after eliminating Sellers' and Buyer's principal outside
     accountants and one additional firm designated as objectionable by each of
     Sellers and Buyer. The determination by the accounting firm so selected of
     the Closing Date Working Capital Statement (with such modifications
     therein, if any, as reflect such determination) shall be conclusive and
     binding upon the parties and deemed final. The fees and expenses of such
     accounting firm in acting under this Section 3.8 shall be shared equally by
     Buyer and Sellers.

         (e)  If the Closing Date Working Capital identified on the final
     Closing Date Working Capital Statement is not less than the Minimum Working
     Capital, then Buyer shall pay the entire Holdback Amount to Sellers, plus
     5% per annum on the Holdback Amount for the period from the Closing Date up
     to the date of Sellers' receipt of such amounts. If the Closing Date
     Working Capital identified on the final Closing Date Working Capital
     Statement is less than the Minimum Working Capital, Buyer shall be entitled
     to retain the Holdback Amount up to the amount of any such shortfall in
     Minimum Working Capital (and Sellers shall not be liable for any further
     shortfall), and shall remit any remaining balance of the Holdback Amount to
     Sellers, plus 5% per annum on such portion of the Holdback Amount for the
     period from the Closing Date up to the date of Sellers' receipt of such
     amounts. Payment shall be made by the party obligated to make such payment
     not more than 5 business days following the determination of the final
     Closing Date Working Capital Statement pursuant to Section 3.8(d) or (e) in
     the manner described in Section 3.2.

                   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 sections of this
Master Agreement), 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 organized, validly existing and in good standing under the laws of the
jurisdiction where it is organized and has all requisite corporate power and
authority to carry on the Business as currently conducted by it and to own or
lease and to operate the properties of the Business used by it.  Each

                                     -11-
<PAGE>

Seller is qualified to do business in each state of the United States in which
the Business is conducted that requires such qualification and where the failure
to so qualify would have a Material Adverse Effect on the Business. For the
purposes of the Transaction Documents, a "Material Adverse Effect on the
Business" means any change, effect or circumstance that, individually or when
taken together with all other similar changes, effects or circumstances,
constitutes a material adverse change in, or has a material adverse effect on,
the assets, liabilities, business or operations of the Transferred Assets or the
Business taken as a whole.

     4.2   Corporate Authorization; Enforceability.

     (a)   Subject to 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 have been duly authorized by
     all necessary corporate and other action on the part of each Seller.
     Subject to 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.

           (b)   Subject to 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 such Seller, enforceable
     in accordance with its terms.

     4.3   Charters and Bylaws; No Conflict; Capitalization of Transferred
Subsidiary

           (a)   Copies of the charters and bylaws and other organizational
     documents of the Sellers have been made previously available to Buyer, and
     each such copy is true, correct and complete.

           (b)   Except as set forth in Schedule 4.3(b) and assuming the filing
     of the Bankruptcy Case, neither the execution and delivery of this Master
     Agreement or the Ancillary Agreements executed or to be executed by
     Sellers, nor the consummation of the Contemplated Transactions will (i)
     result in the acceleration of, or the creation in any party of any right to
     accelerate, terminate, modify or cancel any material indenture, contract,
     lease, sublease, loan agreement, note or other obligation or liability to
     which any of the Sellers is a party or by which it is bound or to which any
     of its assets is subject, (ii) conflict with or result in a breach of or
     constitute a default under any provision of the Certificate of
     Incorporation or Bylaws (or other charter documents) of a Seller, or a
     default under or violation of any material restriction, lien, encumbrance,
     indenture, contract, lease, sublease, loan agreement, note or other
     obligation or liability to which it is a party or by which it is bound or
     to which any of its assets is subject or result in the creation of any lien
     or encumbrance upon any of said assets, or (iii) violate or result in a
     breach of or constitute a default under any judgment, order, decree, rule
     or regulation of any court or governmental agency to which a Seller is
     subject, and which, in each of clauses (i), (ii) and (iii) above, would
     have a Material Adverse Effect on the Business.

                                     -12-
<PAGE>

           (c)   Schedule 4.3(c) sets forth the authorized and outstanding
     capital stock of the Transferred Subsidiary and all such capital stock is
     owned beneficially and of record by the Sellers in the percentages set
     forth on Schedule 4.3(c). Except as set forth on Schedule 4.3(c), the
     Transferred Subsidiary does not have any outstanding securities convertible
     into or exercisable for any shares of its capital stock, 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 its capital stock or any
     securities convertible into or exchangeable or exercisable for any shares
     of its capital stock.

     4.4   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) a filing with the Federal Trade Commission
and the Department of Justice under the HSR Act, (b) Bankruptcy Court approval,
and (c) 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 Foreign Subsidiaries, (b) balance sheets
for the Foreign 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").  Except as set
forth on Schedule 4.5, the Financial Statements have been prepared in accordance
with the accounting records and policies of Kaiser and with GAAP, and reasonably
present in all material respects the Transferred Assets and the Assumed
Liabilities of the Business as of the dates thereof.

     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.

     4.7   Title to Transferred Assets.

           (a)   Except as set forth on Schedule 4.7(a), and except for real and
     personal property subject to valid leases, each Seller has good and
     marketable title to or other valid ownership rights in the Transferred
     Assets, other than liens and encumbrances which will be released or
     discharged on or prior to the Closing Date. This Section 4.7 does not apply
     to the Transferred Intellectual Property.

           (b)   Schedule 4.7(b) 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

                                     -13-
<PAGE>

     reasonably be expected to affect the rights and privileges of any Seller
     under an Assumed Contract and which reasonably could be expected to have a
     Material Adverse Effect on the Business. Except as provided on Schedule
     4.7(b), 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 could
     reasonably be expected to cause a Material Adverse Effect on the Business.
     Except as set forth on Schedule 4.7(b), Sellers have obtained any Consent
     necessary under any personal property lease to enter into the Contemplated
     Transactions.

     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 in the
     manner as currently conducted by the Sellers in all material respects.

           (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 or have been overtly threatened as of
     the date of this Master Agreement (i) to the effect that the sale,
     licensing or use of any of the products 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 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)   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 the Buyer to utilize the Transferred Intellectual Property or otherwise
     impair its value in any manner which could reasonably be expected to 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 active Contracts constituting:

           (a)   All customer contracts and open purchase orders of the Business
     (i) with a reasonably expected value in excess of $250,000 per annum, (ii)
     providing for loss sharing or indemnification other than for damages
     resulting from the negligence or willful misconduct in the performance of
     the contract by the contracting Seller, or (iii) anticipated

                                     -14-
<PAGE>

     to result in a loss to Seller which could reasonably be expected to have a
     Material Adverse Effect on the Business;

           (b)   All pending bids for customer contracts with a reasonably
     expected value in excess of $250,000 per annum;

           (c)   All outstanding contracts with the officers, directors and
     employees of Seller relating to the Business and providing for total
     consideration in excess of $80,000 per annum, other than contracts which by
     their terms are cancelable by Seller with notice of not more than 30 days
     (except as required by any state laws) and without cancellation penalties
     or severance payments;

           (d)   All collective bargaining agreements applicable to the
     Business;

           (e)   All consulting agreements in excess of $50,000 to which any of
     the Sellers is a party in connection with the conduct of the Business;

           (f)   All joint venture, teaming and similar arrangements to which
     the Sellers are parties in connection with the Business;

           (g)   All agreements for the purchase by a Seller of equipment
     specific to the Business involving outstanding commitments in excess of
     $250,000;

           (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 $250,000 by one
     or more Sellers;

           (i)   All leases of real property or leases of personal property
     involving payments of more than $50,000 per annum to be assumed by Buyer;
     and

           (j)   All agreements materially limiting the freedom to compete in
     the Business with any Person or other entity or in any geographical area.

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, 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 could reasonably
be expected to have a Material Adverse Effect on the Business following the
Closing Date.  As of the date of this Master Agreement, 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 could
reasonably be expected to have a Material Adverse Effect on the Business
following the Closing Date.

     4.11  Licenses and Permits.

                                     -15-
<PAGE>

           (a)   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, including
     the Permits identified on Schedule 4.11(a) hereto.

           (b)   Except as set forth on Schedule 4.11(b), (i) each of said
     Permits is in full force and effect, (ii) the Business is in compliance
     with the terms, provisions and conditions thereof, except where the failure
     to be so in compliance could not reasonably be expected to result in a
     Material Adverse Effect on the Business, (iii) there are no outstanding
     violations, notices of noncompliance, judgments, consent decrees, orders or
     judicial or administrative actions, and to Sellers' Knowledge,
     investigations or proceedings, adversely affecting any of said Permits,
     which could reasonably be expected to have a Material Adverse Effect on the
     Business following the Closing Date, and (iv) 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, the
conduct of the Business has at all times complied and currently complies with
all Environmental Laws, except where the failure to so comply could not
reasonably be expected to result in a Material Adverse Effect on the Business.
As it relates to the Business and except as set forth in Schedule 4.12: (i) no
Seller has arranged for disposal or treatment, or arranged with a transporter
for transport for disposal or treatment, of any Hazardous Material on any third
party property that has resulted or may reasonably be expected to result,
individually or in the aggregate, in any liability which could reasonably be
expected to result in a Material Adverse Effect on the Business; (ii) no Seller
has exposed any employee or third party to any Hazardous Material or condition
that has resulted or may reasonably be expected to result, individually or in
the aggregate, in any liability which could reasonably be expected to result in
a Material Adverse Effect on the Business; (iii) no Seller has received any
notice, demand, letter, claim or request for information relating to the
Business which alleges violation of or liability under any Environmental Law and
there are no proceedings, actions, orders, decrees, injunctions or other claims,

otherwise alleging liability under any Environmental Law; and (iv) no Seller has
entered into any indemnity agreements or other contracts in which it has agreed
to assume the liabilities of any other party for which a Seller was not already
liable under any Environmental Law. "Environmental Laws" shall mean all
applicable U.S. and foreign federal, state and local laws, ordinances and
regulations pertaining to air and water quality, Hazardous Materials, waste,
disposal or other environmental matters, including the Clean Water Act, the
Clean Air Act, the Federal Water Pollution Control Act, the Solid Waste Disposal

                                     -16-
<PAGE>

     4.13  Absence of Certain Business Practices.  No Seller nor any officer or
employee of any Seller, or to Sellers' Knowledge 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
           employees

                 (i)   located at the Transferred Facilities,

                 (ii)  employed by the Transferred Subsidiary and each of the
          Foreign Subsidiaries, or

                 (iii) who are primarily engaged in the Business,

     and for all of which Buyer will be responsible pursuant to Section 2.3(d)
     and Article 6 (such employees being collectively referred to herein as
     "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), there are no
     documented material employment-related disputes, grievances, or
     disciplinary actions pending or, to Sellers' Knowledge, threatened, by or
     between any of the Sellers and any Employees of the Business.

           (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 or other foreign or U.S. labor board or
     administration, or any unfair labor practice decision, nor, to Sellers'
     Knowledge, is there any valid basis for such an order.

                                     -17-
<PAGE>

           (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, nor, to Seller's
     Knowledge, is there any valid basis for any proceeding described in this
     Section 4.15(b). 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 and accrued on the Closing Financial Statements. Except for
     those liabilities that constitute Assumed Liabilities, Buyer shall have no
     liability for any claims identified in this Section 4.15(d).

     4.16  Seller Benefit Plans.

           4.16.1  United States.

           (a)   Schedule 4.16.1(a) sets forth each employee welfare benefit
     plan, as defined in Section 3(1) of ERISA (a "Welfare Plan") and employee
     pension benefit plan, as defined in Section 3(2) of ERISA (a "Pension
     Plan") relating to the Business, as well as consulting, deferred
     compensation, employment agreement, severance, vacation, holiday, sickness,
     educational assistance, insurance, incentive compensation and bonus plans,
     programs and arrangement (a "Benefit Arrangement"), under which Sellers
     have any obligation with respect to any employee, former employee, director
     or beneficiary of the Business, (collectively, the "Plans"). Except as set
     forth in Schedule 4.16.1 (a) attached hereto, Sellers have furnished to
     Buyer true and correct copies of documents evidencing the Plans, including
     all amendments thereto.

           (b)   Except as set forth on Schedule 4.16.1(b) attached hereto, none
     of the Pension Plans is a multi-employer plan within the meaning of Section
     3(37) of ERISA, and neither Sellers nor any entity which is required to be
     treated as a single employer with Sellers pursuant to Section 414(b) or (c)
     of the Tax Code (an "ERISA Affiliate") has maintained or sponsored, has
     been required to contribute to, has terminated or withdrawn (either
     completely or partially) from, any such multi-employer plan and no
     withdrawal liability (as defined in Section 4201, 4063 or 4064 or ERISA)
     has been incurred by Sellers or an ERISA Affiliate with respect to any
     defined benefit plan or multi-employer plan, and

                                     -18-
<PAGE>

     there is no basis to anticipate that any demand for payment of any
     withdrawal liability will be made upon Sellers or an ERISA Affiliate. None
     of the Plans and no Pension Plan maintained by an ERISA Affiliate is
     subject to Title IV of ERISA or Section 412 of the Tax Code and during the
     six (6) year period preceding the Closing Date, neither Sellers nor any
     ERISA Affiliate has incurred any liability under Title IV of ERISA which
     has not been satisfied. Neither Sellers nor any ERISA Affiliate has
     terminated any defined benefit pension plan subject to Title IV of ERISA
     during the six (6) year period preceding the Closing Date for which Sellers
     or an ERISA Affiliate has not received a favorable determination letter
     from the Internal Revenue Service, a copy of which has been provided to
     Buyer by Sellers.

           (c)   The Plans have been administered in compliance with their terms
     and with all filing, reporting, disclosure, and other requirements of ERISA
     and the Tax Code. Each Plan which is a group health plan (within the
     meaning of Section 4980B(g)(2) of the Tax Code) has complied at all times
     with the health care continuation coverage requirements of Section 4980B of
     the Tax Code and Part 6 of Title I of ERISA and the group health plan
     portability access and renewability requirements of Sections 9801 et seq.
     of the Tax Code and Part 7 of Title I of ERISA. Each Plan (together with
     its related funding instrument) which is a Pension Plan is qualified under
     Section 401 of the Tax Code and the regulations issued thereunder, and has
     been so qualified from the date of its adoption to the date of this
     Agreement, and each such Plan and its related funding instrument have been
     the subject of a favorable determination letter issued by the Internal
     Revenue Service to the effect that such Plan and funding instrument are so
     qualified. A copy of each determination letter, which has been issued by
     the Internal Revenue Service and which is in Sellers' possession with
     respect to each Plan which is a Pension Plan, has been provided to Buyer by
     Sellers.

           (d)   Except as set forth on Schedule 4.16.1(d), none of the Plans
     which is a Welfare Plan provides benefits to retirees or other former
     employees of Sellers, regardless of whether such benefits are vested, and
     except as set forth on Schedule 4.16.1(d) Sellers have not terminated any
     employee welfare benefit plan providing benefits to retirees.

           (e)   Neither Sellers nor any ERISA Affiliate nor any of their
     employees or directors, nor any plan fiduciary of any of the Pension Plans,
     has engaged in any transaction in violation of Section 406(a) or (b) of
     ERISA or any "prohibited transaction" (as defined in Section 4975(c)(1) of
     the Tax Code) for which no exemption exists under Section 4975(d) of the
     Tax Code and which could subject any of the Plans or any fiduciary of any
     of the Plans to any tax or penalty imposed by Section 4975 of the Tax Code
     or 502 of ERISA, and no "reportable event" (as defined in Section 4043 of
     ERISA and the regulations promulgated thereunder), other than such as may
     arise out of the communication of the transactions contemplated by the
     Agreement, has occurred in connection with any Pension Plan.

           (f)   Except as set forth in Schedule 4.16.1(f), other than routine
     claims for benefits made in the ordinary course of business, there are no
     claims, investigations or causes of action ("Claims") pending or, to
     Sellers' Knowledge, threatened against any Plan or fiduciary of any such
     Plan by any participant, beneficiary or governmental agency

                                     -19-
<PAGE>

     with respect to the qualification or administration of any such Plan, and
     there is no basis to anticipate that any such Claim will be made.

           (g)   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 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.

           (h)   Except as set forth in Schedule 4.16.1(h), Sellers have
     provided to Buyer a copy of all related trust agreements and any amendment
     thereto together with the three most recent annual Form 5500 reports, the
     most recent summary plan description and any subsequent summary of material
     modification, the three most recent summary annual reports, any insurance
     contracts, and any employee handbooks, manuals and policy statements
     relating to the Plans.

           (i)   Sellers have not made employer contributions, other than
     elective tax-deferred contributions and employer matching contributions on
     behalf of participants, to the Plans which are Pension Plans for the 1999
     and 2000 plan years.

           (j)   Except as set forth on Schedule 4.16.1(j), neither the
     execution and delivery of this Agreement nor any of the transactions
     contemplated herein will terminate or modify, or give a third person a
     right to terminate or modify, the provisions or terms of any Plan, and will
     not constitute a stated triggered event under any Plan that will result in
     any payment (including parachute payments, severance payments or any
     similar payments) becoming due to any employees of Sellers.

           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 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 (to the extent established and formally communicated to
     employees), 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 ("Government
     Sponsored or Mandated Plans"). The plans, programs and arrangements set
     forth on Schedule 4.16.2, which include a listing of all Government
     Sponsored or Mandated Plans, are referred to herein as the "Non-U.S.
     Employee Benefit Plans."

                                     -20-
<PAGE>

           (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
     compliance with all material requirements of Applicable Law and the terms
     of each such plan; 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 to the Sellers'
     Knowledge, 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.

           (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 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 could not reasonably be 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 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-

                                     -21-
<PAGE>

     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.

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

     4.20  Taxes.

           4.20.1  Transferred Subsidiary.  Except as set forth on Schedule
     4.20.1 attached hereto and made a part hereof:

                   (a)  the Transferred Subsidiary has, or will have prior to
          the Closing Date:

                        (i)  timely filed, or timely filed extensions with
               respect to, all federal, foreign, state, and local Tax Returns
               required to be filed by or with respect to the Transferred
               Subsidiary prior to the Closing Date and all such Tax Returns are
               true, complete and correct; and

                        (ii) timely paid in full, or accrued on the Closing

               Date.

               (b)      The Transferred Subsidiary is not a party to any pending
          action or proceeding, nor, to Sellers' Knowledge, is any action or
          proceeding threatened by any Governmental Authority for the assessment
          or collection of any Taxes, and no

                                     -22-
<PAGE>

          claim for the assessment or collection of any Taxes has been asserted
          or proposed to be asserted against the Transferred Subsidiary, which
          has not been settled with all amounts due having been paid. There are
          no matters under discussion with any taxing authority which might

          the Transferred Subsidiary.

               (c) There are no agreements, waivers, or other arrangements
          providing for an extension of time with respect to the assessment of
          any Tax or deficiency against or relating to the Transferred
          Subsidiary.  There are no outstanding powers of attorney enabling any
          party to represent the Transferred Subsidiary with respect to Tax
          matters which will not be cancelled prior to Closing.

               (d) All Taxes due from the Transferred Subsidiary with respect to
          employee income tax withholding, social security taxes, unemployment,
          and any similar Taxes for all periods ending prior to the Closing Date
          have been either paid in full prior to the Closing Date or will have
          been accrued as a liability on the Closing Financial Statements.

               (e) All other Taxes required to have been withheld or collected
          by the Transferred Subsidiary have been or will have been duly
          withheld and collected and have been duly paid over to the proper
          Governmental Authority, or settled or adequately reserved for on the
          Closing Financial Statements, all as and to the extent prescribed by
          law.

               (f) The reserves for Taxes on the Financial Statements (excluding
          any reserves for deferred taxes) are sufficient for the payment of all
          unpaid Taxes of the Transferred Subsidiary through the dates of such
          Statements and for all periods prior thereto, including, without
          limitation, all Taxes, if any, imposed after such dates but in respect
          of any period or periods prior to the dates of such Statements.

               (g) The Transferred Subsidiary is not a party to any agreement,
          arrangement, or practice for the sharing of Taxes nor is obligated to
          indemnify any other party for Taxes.

               (h) There are no liens for Taxes on any asset of the Transferred
          Subsidiary, other than for Taxes not yet due and payable.

               (i) The Transferred Subsidiary is not a United States real
          property holding company within the meaning of Section 897(c) of the
          Tax Code.

               (j) The Transferred Subsidiary is not subject to an agreement or
          consent under Section 341(f) of the Tax Code.

               (k) The Transferred Subsidiary will not be required to include
          any adjustment in taxable income for any period ending on or after the
          Closing Date under Section 481 of the Tax Code (or under any similar
          provision of the Tax laws of any jurisdiction) as a result of a change
          in the method of accounting for a period ending prior to the Closing
          Date or pursuant to an agreement with a Tax authority

                                     -23-
<PAGE>

          with regard to the Tax liability of a Seller or the Transferred
          Subsidiary for any period ending prior to the Closing Date.

               (l) The Transferred Subsidiary's property is not "tax exempt use
          property" within the meaning of Section 168(h) of the Tax Code.

               (m) The assets owned by the Transferred Subsidiary are not
          required to be treated as owned by any other person for federal income
          tax purposes.

               (n) The Transferred Subsidiary is not a party to any joint
          venture, partnership or other arrangement or contract which could be
          treated as a partnership for federal income tax purposes.

               (o) The Transferred Subsidiary has not entered into any sale-
          leaseback or any leveraged lease transaction that fails to satisfy the
          requirements of Revenue Procedure 75-21 and other Internal Revenue
          Service guidance (or similar provisions of foreign law).

               (p) The Transferred Subsidiary is not liable with respect to any
          indebtedness the interest of which is not deductible for applicable
          federal, foreign, state or local income tax purposes.

               (q) The Transferred Subsidiary has withheld prior to Closing,
          proper and accurate amounts from employees of the Transferred
          Subsidiary in compliance with all withholding and similar provisions
          of any and all applicable federal, foreign, state, and local laws,
          statutes, codes, ordinances, rules, and regulations.  All such amounts
          have been timely remitted to the proper governmental authority as
          prescribed by law.

               (r) There are no outstanding rulings of, or requests for rulings
          with, any Tax authority addressed to the Transferred Subsidiary that
          are, or if issued would be, binding on the Transferred Subsidiary.

               (s) Neither the Transferred Subsidiary nor any of the Sellers is
          a party to any agreement, contract, arrangement, or plan that has
          resulted or would result, separately or in the aggregate, in the
          payment of any "excess parachute payments" within the meaning of
          Section 280G of the Tax Code.

               (t) The Transferred Subsidiary has not participated in an
          international boycott as defined in Section 999 of the Tax Code.

               (u) The Transferred Subsidiary is not and has never been a
          "reporting corporation" subject to the reporting requirements of
          Section 6038A of the Code.

               (v) The Transferred Subsidiary does not have a permanent
          establishment in any country other than the United States, as defined
          in any applicable Tax treaty between the United States and such other

          Transferred Assets for all periods prior to the Closing Date.  Each
          such Seller has paid or will pay or finally settle all Taxes shown as

               (b) There are no liens for Taxes (other than for current Taxes

                    REPRESENTATIONS AND WARRANTIES OF BUYER

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

     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.

     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

                                     -25-
<PAGE>

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 and each Buyer Designee has 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 or any Buyer Designee, as the case may be.

     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 and Buyer Designee, as the case may be,
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 and any Buyer Designee pursuant to this Master
Agreement, and the consummation of the Contemplated Transactions, will not
conflict with or result in any violation of or default under any provision (a)
of the charter or bylaws of Buyer and any Buyer Designee, 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 and any
Buyer Designee or any of its properties or assets, the result of which, with
respect to items identified in clause (b) would materially impair the ability of
Buyer or any Buyer Designee to consummate the Contemplated Transactions (a
"Material Adverse Effect on Buyer").

     5.5  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 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
Ancillary Agreements, other than (a) a filing with the Federal Trade Commission
and the Department of Justice under the HSR Act, (b) Bankruptcy Court approval,
and (c) 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 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, and has been given the
opportunity to meet with officers and other representatives of Kaiser for the
purpose of investigating and obtaining information regarding the Business
operations and its financial and legal affairs.

                                     -26-
<PAGE>

     5.8   Financial Capacity. Buyer, either individually or with its direct and
indirect parent companies, has the financial capacity to consummate the
Contemplated Transactions. Buyer has heretofore provided to Kaiser an accurate
written explanation of the means by which Buyer plans to finance the
Contemplated Transactions.

     5.9   Brokers. No agent, broker, Person or firm acting on behalf of Buyer
or its stockholders is, or will be, entitled to any commission or broker's 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.  Buyer is not aware of any fact, circumstance or
condition which would constitute a 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.

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. All such employees who accept Buyer's offer of
employment and all employees of Foreign Subsidiaries shall be referred to herein
as "Transferee Employees." Transferee Employees shall become eligible to
participate in the employee benefit plans and arrangements maintained by Buyer,
including severance benefit, in the same manner as similarly situated employees
of Buyer. 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.

     6.2   Severance Obligations. Following the Closing, Terminated Employees
shall receive severance and accrued vacation benefits, if any, under the Welfare
Plans and Benefit Arrangements of Sellers and Buyer shall reimburse Sellers at
Closing for the payment of any such amounts which may be due pursuant to Section
3.2. Notwithstanding anything contained herein to the contrary, Buyer shall have
no payment obligation to any Employee of the Business who is, in good faith,
offered employment by Buyer and does not accept such employment. For purposes of
this Section 6.2, a "good faith" offer shall mean an offer that includes (i) a
salary of not less than 95% of an employee's current salary, (ii) employment
within 50 miles of an employee's current work location or place of residence,
and (iii) a position comparable to an employee's current position. Buyer
acknowledges that it has not informed Sellers of any planned or

                                     -27-
<PAGE>

contemplated decisions or actions by Buyer or one of its subsidiaries that would
require service of notice under the WARN Act.

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

     6.4   Plans, Benefits and Policies.

           (a)   Except as otherwise provided herein, Buyer and its Subsidiaries
     shall, as of the Closing Date, adopt and provide Transferee Employees whose
     employment is based in the United States with compensation, Pension Plans,
     Welfare Plans, and Benefit Arrangements substantially equivalent in the
     aggregate to Buyer's compensation, Pension Plans, Welfare Plans, and
     Benefit Arrangements maintained for similarly situated employees of Buyer.

           (b)   Buyer and its Subsidiaries shall credit Transferee Employees
     with service with Sellers (and predecessors of Sellers) for purposes of
     vesting, eligibility and the determination of benefits under vacation and
     severance pay plans. The Sellers shall take all necessary actions to fully
     vest all Employees of the Business in their benefits under any Pension Plan
     maintained by a Seller as of the Closing Date.

           (c)   The 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.

           (d)   The 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.

           (e)   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 Plans of Sellers.

           (f)   Sellers or the applicable employee benefit programs
     administered by Sellers shall be responsible for benefits accrued or claims
     incurred prior to the Closing Date with respect to Transferee Employees and
     their eligible dependents in accordance with the provisions of the
     applicable Sellers' employee benefit programs 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 Sellers' medical plans that commenced before the Closing Date; (iii)
     health care benefits for services rendered or materials received under
     Sellers' medical plans before the Closing Date; and (iv) worker's
     compensation benefits for disabilities resulting from an accident or
     occurrence while employed by a Seller or a Subsidiary of a Seller or a
     predecessor thereof which occurred prior to the Closing Date.

                                     -28-
<PAGE>

           (g)   After Closing, (i) Buyer and Sellers shall 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, and (ii)
     welfare benefits shall be provided to the Transferee Employees for a
     limited period of time pursuant to the provisions of the Transition
     Services Agreement.

           (h)   No provision in this Section 6.4 shall create any third-party
     beneficiary rights in any employee or former employee (including any
     beneficiary or dependent thereof) of Kaiser, any Seller or any of their
     Affiliates.

     6.5   Foreign Employees.    As of the Closing Date Buyer shall provide
benefit plans for Transferee Employees whose employment is based outside the
U.S. which are reasonably equivalent, in the aggregate, to those provided by
Sellers immediately prior to the Closing Date, subject to the right of Buyer,
Buyer Designee and their Subsidiaries to amend or terminate such benefit plans.
For the avoidance of doubt and without derogation of any other provision hereof,
Buyer agrees that it will indemnify and hold harmless Sellers for all
Liabilities and obligations owed by each Foreign Subsidiary to or for the
benefit or account of such foreign employees to the extent that such Liabilities
and obligations exceed the amount of Sellers' liability therefor had the capital
stock of the Foreign Subsidiaries been transferred to Buyer rather than assets.

     6.6   Bonuses.  Sellers and Buyer agree that Employees of the Business who
become Transferee Employees shall be enrolled in Buyer's 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
Schedule 6.6. identifying each employee entitled to a bonus and the bonus
accrual for such employee.

                              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.

                                     -29-
<PAGE>

           (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 of business;

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

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

                 (iv)   cancel, compromise, knowingly waive or lease any
                        material right or claim (or series of related rights and
                        claims), outside the ordinary course of business;

                 (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 of business consistent
                        with past practice in the compensation payable to
                        Employees of the Business and payments pursuant to any
                        Retention Arrangements;

                 (vi)   enter into any Contract with a customer providing for
                        the provision of more than $250,000 of goods and/or
                        services or submit a binding offer or bid with respect
                        to any such work;

                 (vii)  enter into any joint venture, risk-sharing,
                        indemnification or other agreement or commitment of
                        similar effect outside of the ordinary course of
                        business; and

                 (viii) 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.

                                     -30-
<PAGE>

           (d)   Notwithstanding anything to the contrary contained herein, (i)
     at any time prior to the Closing, Sellers may cause any asset of the
     Transferred Subsidiary that would not be included in the Transferred Assets
     if the assets, rather than the stock, of such 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 the Transferred Subsidiary any inter-company receivable or inter-
     company payable, so that at and after the Closing the Transferred
     Subsidiary shall not owe, or have the right to receive from, Kaiser or any
     of its other Subsidiaries any amount for goods, services or cash advanced
     or other extensions of credit provided prior to the Closing.

     7.2   Use of Business Names by Buyer.

           (a)   Buyer acknowledges that Sellers have 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)   For a period of six months from the Closing Date or, with
     respect to any Assumed Contract obligation that requires a novation by the
     U.S. Government, until such contract is novated (the "Window Period"),
     Seller shall and hereby irrevocably grants, effective as of the Closing
     Date, on a fully-paid, royalty-free basis, to Buyer, the right to use the
     Kaiser and Kaiser Engineers Logos and the Kaiser and Kaiser Engineers Names
     in connection with the operation of the Business as currently conducted
     including, during the Window Period, to (i) market and sell all such
     services and products produced by the Business and (ii) use any other
     assets on hand included in the Transferred Assets, including, without
     limitation, any catalogs, invoices, packaging material or stationery,
     bearing the Kaiser and Kaiser Engineers Names or Kaiser and Kaiser
     Engineers Logos (provided, however, that Buyer shall use its commercially
     reasonable efforts to cease its use of the Kaiser and Kaiser Engineers
     Names and the Kaiser and Kaiser Engineers Logos within the Window Period).
     Immediately upon the expiration of the Window Period, Buyer shall cease to
     use in any manner the Kaiser and Kaiser Engineers Names and the Kaiser and
     Kaiser Engineers Logos incorporating such Names and remove or obliterate
     such Names and the Kaiser and Kaiser Engineers Logos from any products or
     other assets and clearly and prominently mark the new name of the Business
     thereon, 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.

     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

                                     -31-
<PAGE>

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 (including without limitation for the purpose of preparing
the Closing Date Working Capital Statement). 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   Non-Competition.

           (a)   Sellers agree that, as part of the consideration for the
     payment by Buyer of the Purchase Price, for a period of three (3) years
     immediately following the Closing Date, none of Sellers nor any of their
     divisions or Affiliates will, directly or indirectly, operate, perform,
     have any interest in or otherwise be engaged in or concerned with a
     business which performs services in competition with the Business. For
     these purposes, ownership of securities of a company whose securities are
     publicly traded under a recognized securities exchange not in excess of 10%
     of any class of such securities shall not be considered to be competition
     with Buyer, and engaging in the activities identified in Section 2.2(q) of
     this Master Agreement and contracts resulting therefrom, and engaging in
     any bids for and/or contracts with the Federal government (other than as
     related to the subject matter of any Assumed Contracts) shall also not be
     considered to be competition with Buyer.

           (b)   Further, Sellers agree that for a period of two (2) years
     following the Closing Date none of Sellers nor any of their Affiliates will
     induce any of the Transferee Employees hired by Buyer on the Closing Date
     to terminate his or her relationship with Buyer and to work in a business
     that competes with the Business.

           (c)   Each of Sellers and Buyer acknowledges that the restrictions on
     its activities under Sections 7.4(a) and (b) hereof (as the case may be)
     are necessary for the reasonable protection of Buyer and Sellers (as the
     case may be) and constitute a material inducement to Buyer's entering into
     and performing this Master Agreement. Each of Sellers and Buyer further
     acknowledges, stipulates and agrees that a breach of any of such
     obligations and agreements will result in irreparable harm and continuing
     damage to the other party for which there will be no adequate remedy at law
     and further agrees that in the event of any breach of said obligations and
     agreements, the other party and its successors and assigns will be entitled
     to injunctive relief and to such other relief as is proper under the
     circumstances.

                                     -32-
<PAGE>

           (d)   For the avoidance of doubt, Buyer acknowledges that the
     restrictions imposed in Section 7.4(a) and (b) shall only apply to Kaiser
     and its Subsidiaries, but shall not impose any restrictions on the
     activities of any other Person, including, without limitation, a Person
     which purchases assets (including the capital stock of Subsidiaries) of
     Kaiser or its Subsidiaries, or any such purchaser's Subsidiaries, or any
     investor in, or purchaser of, Kaiser and/or any of its Subsidiaries, or any
     Affiliate of any such investor other than Kaiser and its Subsidiaries.

     7.5   Acquisition Proposals.  Kaiser specifically agrees that neither
Sellers nor any representative acting on their behalf 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 unreasonably interfere with the Business or with the
performance of any Seller's employees.

     8.2   Assistance with Respect to Excluded Assets.  Following the Closing
Date, upon request of any Seller, Buyer will use its commercially reasonable
efforts to assist such Seller in connection with collection of accounts
receivable related to the Excluded Assets.  To the extent Buyer receives payment
in respect of such items following the Closing Date, Buyer shall promptly pay
such amounts to such Seller.

                                   ARTICLE 9

                           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   HSR Filing; Other Filings.

           (a)   Not later than five business days after the date hereof and
     pursuant to the applicable requirements of the HSR Act and the rules and
     regulations thereunder, Buyer and Kaiser shall cause to be filed with the
     Federal Trade Commission and the Antitrust Division of the Department of
     Justice all requisite documents and notifications in

                                     -33-
<PAGE>

     connection with the Contemplated Transactions. Buyer and Kaiser shall
     diligently and expeditiously comply with the HSR Act in connection with
     securing all necessary approvals or waivers thereunder.

           (b)   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 and paying such fees 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 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;

                                     -34-
<PAGE>

           (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, foreign
     withholding, registration, transfer, conveyance, excise, recording, license
     and other similar Taxes and fees (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.
     However, notwithstanding anything herein to the contrary, Buyer will be
     responsible for foreign withholding taxes up to the first U.S.$400,000 and
     Sellers will be responsible for the remainder, if any.

           (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 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,
to the extent it has books and records in its possession, 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

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 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
     Subsidiary 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
     (or any state consolidated, combined, unitary or similar group) (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 Subsidiary 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 prepare or cause to be prepared in a manner
     consistent with past practice, and timely file or cause to be timely filed,
     all Tax Returns in respect of (i) Taxes of the Transferred Subsidiary and
     (ii) Taxes otherwise related to the Business for taxable years or periods
     ending on or prior to the Closing Date. Tax Returns of the Transferred
     Subsidiary shall be subject to the Buyer's approval and shall be delivered
     to the Buyer at least thirty (30) days prior to the due date for review and
     approval. Tax Returns which include periods ending on or prior to the
     Closing Date, and which must be signed by an officer of the Transferred
     Subsidiary, shall be delivered to the Buyer not less than fifteen (15) days
     prior to the due date, including any extensions thereof. The Transferred
     Subsidiary will pay the Taxes due with respect to its Tax Returns.

           (c)   Kaiser shall have the sole right (but not the obligation), at
     its sole expense and for its sole benefit, to prepare and file or cause to
     be prepared and filed 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 Subsidiary or Taxes otherwise related to the Business
     with respect to periods ending on or prior to the Closing Date.

           (d)   Buyer shall file or cause to be filed when due all Tax Returns
     in respect of (i) Taxes of the Transferred Subsidiary and (ii) Taxes
     otherwise related to the Business 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 Return for such taxable years or periods.

                                     -36-
<PAGE>

           (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 Subsidiary with respect to periods
     ending after the Closing Date.

           (f)   Buyer and Sellers agree that, in accordance with the
     "Alternative Procedure" provided in Section 5 of Revenue Procedure 96-60
     1996-53 Cumulative Bulletin 24, with respect to filing and furnishing IRS
     forms W-2, W-3 and 941, from and after the Closing Date (i) Sellers shall
     be considered a "predecessor" employer and Buyer shall be considered a
     "successor" employer with respect to any of the Transferee Employees, (ii)
     Sellers shall be relieved of furnishing forms W-2 to the Transferee
     Employees to whom it would have been obligated to furnish such forms for
     the present calendar year, and (iii) Buyer shall assume the obligations of
     Seller to furnish such forms to employees for the present calendar year.

           (g)   In the event Buyer causes or permits the Transferred Subsidiary
     to sell assets on the Closing Date or take any other action not in the
     ordinary course of business that would otherwise result in the reporting of
     income on Kaiser's consolidated return pursuant to Treas. Reg. (S) 1.1502-
     76(b)(1)(ii), Buyer agrees that such income should be reported on the
     separate tax return of Transferred Subsidiary (or the consolidated return
     of any new consolidated group of which the Transferred Subsidiary will
     become a member) pursuant to the "next day" rule of Treas. Reg. 1.1502-
     76(b)(1)(ii)(B). Buyer agrees to indemnify and hold harmless Kaiser for any
     such liability.

           9.8.2 Tax Liability.  Whenever it is necessary for purposes of this
Master Agreement to determine the Tax Liability of the Transferred Subsidiary or
Taxes otherwise related to the Business for a taxable year or period that begins
before and 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
Closing Date and by using the accounting practices and procedures previously
used by Kaiser 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 based on the fiscal tax year to which such Taxes relate as of the
Closing Date as set forth on 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

                                     -37-
<PAGE>

     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.

           (b)   Kaiser and each other member of Seller Consolidated Group, and
     Buyer and the Transferred Subsidiary, 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 the
     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.

           (a)   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 Subsidiary for periods from and after
     the Closing Date shall be made after the date of this Master Agreement
     without the prior written consent of both Kaiser and Buyer. In the event
     Buyer chooses not to make a Section 338(h)(10) Election, Kaiser, in its
     sole discretion, may reattribute net operating loss and net capital loss
     carryovers of the Transferred Subsidiary to itself pursuant to Treas. Reg.
     (S) 1.1502-20(g). Buyer shall cooperate fully, and shall cause the
     Transferred Subsidiary to cooperate fully, in any such election pursuant to
     Treas. Reg. (S) 1.1502-20(g) made by Kaiser.

                                     -38-
<PAGE>

           (b)   At Buyer's option, Sellers shall join with Buyer in making an
     election under Tax Code Section 338(h)(10) and any corresponding elections
     under state, local, and foreign tax law with respect to the purchase and
     sale of the stock of the Transferred Subsidiary (a "Section 338(h)(10)
     Election").  Buyer and Sellers shall cooperate fully with each other in
     making such Section 338(h)(10) Elections.  In particular, and not by way of
     limitation, Buyer and Sellers shall jointly execute necessary copies of
     Internal Revenue Service Form 8023 (or any successor or corresponding form
     or report) and all attachments required to be filed therewith pursuant to
     applicable regulations.  Kaiser shall also pay any Tax imposed on the
     Transferred Subsidiary attributable to the making of the Section 338(h)(10)
     Election, including but not limited to (a) any Tax imposed under Treas.
     Reg. Section 1.338(h)(10)-1T(d)(2), or Treas. Reg. Section 1.1502-6, or (b)
     any state, local or foreign Tax imposed on the Transferred Subsidiary as a
     result of the Section 338(h)(10) Election.

     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 the
     directors, officers, employees, agents and advisors of Buyer and Sellers to
     maintain in confidence, and not use to the detriment of another party,
     Sellers or the Transferred Subsidiary any written, oral, or other
     information obtained in confidence from the other party, or Sellers or the
     Transferred Subsidiary 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 or 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 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 thereof, however stored, and, if requested by the
     other party, shall certify conformity with this Section 9.10(b) in writing.

     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  Mutual Cooperation.  Buyer shall, and shall cause one or more of the
Buyer Designees acquiring assets from Kaiser's Brazilian Foreign Subsidiaries
to, cooperate with one or more Sellers (or their Affiliates, successors or
assignees), on terms mutually agreeable to Buyer and the affected Sellers (or
their Affiliates, successors or assignees), in connection with bids and any
subsequent associated services by Seller(s) (or their Affiliates, successors or
assignees) for alumina contracts in Brazil identified on Schedule 2.2(q).

                 BUYER PROTECTIONS:  OVERBIDDING PROCEDURES AND
                                 BREAK-UP FEES

     10.1  Bankruptcy Court Approvals.  As promptly as practicable after
commencement of the Bankruptcy Case, Sellers subject to the Bankruptcy Case
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 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").

     10.2  Obtaining the Orders.  Sellers shall use 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) Five Hundred Thousand Dollars
     ($500,000);

           (b)   Any bidder making a Competing Bid (a "Competing Bidder") shall
     be required to deliver to the Sellers and to file with the Bankruptcy Court
     an executed copy of an agreement substantially similar to this Master
     Agreement (the "Competing Bid Agreement") on or before ten (10) 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 certified check drawn to the order
     of the Sellers in an amount equal to three percent (3%) 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 acceptable to Kaiser). If one
     or more Competing Bid Agreements is submitted, and after an opportunity for
     Buyer and all parties who have submitted conforming Competing Bid
     Agreements to submit additional higher and better bids (each successive
     Competing Bid Agreement shall be in increments of not less than $500,000 in
     each successive round of

                                     -40-
<PAGE>

bidding), the Sellers will request the Bankruptcy Court to determine the
prevailing Competing Bidder; if so determined, the prevailing Competing Bidder
shall execute and deliver at the Sale Hearing an instrument of irrevocable
commitment 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, the 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, the Buyer shall be paid a break-up
fee of three percent (3%) of the Purchase Price (the "Break-Up Fee"); provided
however, notwithstanding anything herein to the contrary, no 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 had, prior to the issuance of such order of the Bankruptcy Court,
terminated this Master Agreement pursuant to Section 13.1(c)(ii).

     (e) Subject to Section 10.3(f), Buyer shall be entitled to payment of the
Break-Up Fee if 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 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 except as
provided for in Section 13.3. Except as provided in this Section 10.3, 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) As soon as reasonably practicable following the earlier of the
expiration or waiver of Buyer's right to terminate this Agreement pursuant to
Section 13.1(f), 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.

Master Agreement.  In addition to any right to the Break-Up Fee described above,
Buyer shall be entitled to the refund of its Deposit, together with any interest
