ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On September 30, 1995, Foster Wheeler Corporation (the "Company")
completed the acquisition of the power generation business of A. Ahlstrom
Corporation, a privately held Finnish corporation ("Pyropower"), for a purchase
price of approximately $200 million.  The acquisition of Pyropower consisted of
the purchase of stock in the United States, Europe, Scandinavia and Asia and
assets in Finland and the United States.  The final price is subject to
post-closing adjustments based on Pyropower's financial performance in 1995. The
Company expects this acquisition to be accretive to its 1996 earnings.

         Pyropower is a leader in the design, manufacture and supply of
circulating fluidized bed (CFB) systems (including steam generators that burn a
wide variety of solid fuels) to utility and industrial customers worldwide and
also provides a range of boiler services including plant operations and
maintenance services.  CFB technology accommodates a variety of hard-to-burn
fuels, is environmentally compliant, and is cost-competitive with traditional
steam generator technologies.  Pyropower's products and services are delivered
worldwide through its operations in the United States, Europe and Asia.
Management of the Company believes that the acquisition of Pyropower and its
technology positions the Company to compete successfully for the opportunity to
supply a significant portion of new international power generation projects,
particularly in Scandinavia, eastern Europe and certain parts of Asia and to
participate in the developing market for repowering in the United States and
Europe.

         Pyropower currently has approximately 1,500 employees and 1995 revenues
are expected to approximate $350 million. Pyropower currently has backlog of
approximately $550 million and will become a part of the power generation
segment of the Company's Energy Equipment Group.

         In connection with the acquisition of Pyropower, the Company will
record a one-time reorganization charge against earnings in the fourth quarter
of 1995 of approximately $46 million before taxes.  This charge will result in
substantial ongoing cost savings commencing in 1996.  The restructuring is
likely to include the rationalization of manufacturing capacity and the
reduction of approximately 500 salaried and hourly personnel from a total of
3,200 people in the combined operations.

                  FOSTER WHEELER CORPORATION AND SUBSIDIARIES
                             AND AHLSTROM PYROPOWER


                 The following Pro Forma Unaudited Condensed Combined Balance
Sheet as of June 30, 1995 and the Pro Forma Unaudited Condensed Combined
Statements of Earnings for the year ended December 30, 1994 and the six months

the historical statements of earnings as if the acquisition had been effected at
January 1, 1994.

                 The pro forma unaudited condensed combined financial data has
been prepared on the basis of the assumptions described in the notes to the pro
forma unaudited condensed combined financial data and includes assumptions
relating to the allocation of the consideration paid for Pyropower to the
combined assets and liabilities of Pyropower based on preliminary estimates of
their respective fair values.  The actual allocation of such consideration may
differ from that reflected in the pro forma unaudited condensed combined
financial data after an appropriate review of the fair values of the combined
assets and liabilities of Pyropower has been completed.  Amounts allocated will
be based upon the estimated fair values at the time of acquisition, which could
vary significantly from the amounts as of June 30, 1995.  The acquisition will
be accounted for using the purchase method.

                 The pro forma unaudited condensed combined financial data
presented is not necessarily indicative of the actual results that would have
been achieved had the acquisition closed on the dates assumed herein.

                 The pro forma unaudited condensed combined financial data
should be read in conjunction with the financial statements and related notes
thereto of the Company appearing in its 1994 Form 10-K and its June 30, 1995
Form 10-Q and of Pyropower appearing in this Form 8-K.

                        CONDENSED COMBINED FINANCIAL DATA

                   FOSTER WHEELER CORPORATION AND SUBSIDIARIES
                             AND AHLSTROM PYROPOWER
                            (IN THOUSANDS OF DOLLARS)

1.       The acquisition of Ahlstrom Pyropower (Pyropower) by Foster Wheeler
         Corporation and Subsidiaries (the Company) will be accounted for as a
         purchase. The resulting adjustments, which include the effects of
         converting the Pyropower financial data to U.S. generally accepted
         accounting principles, are based on the historical consolidated
         financial statements of the Company and Pyropower as well as the
         financing of the transaction. Final adjustments will be based upon the
         fair market value of the assets and liabilities of Pyropower and the
         Final Bookings Payment (as defined in the Purchase Agreement). The pro
         forma statements of earnings were translated using average exchange
         rates during the periods. The pro forma balance sheet was translated
         using the exchange rate at June 30, 1995.

         The pro forma unaudited condensed financial data is based on the
         following:

         (a)   The acquisition was assumed to have occurred as of June 30, 1995
               for balance sheet purposes and on January 1, 1994 for statements
               of earnings purposes.

         (b)   The purchase price was funded initially by the long-term
               Revolving Credit Facilities as defined in the Company's
               Registration Statement on Form S-3.

         (c)   The pro-forma adjustments to reflect the effects of the
               transaction are as follows:

               (1)  To record the funding of the working capital deficiency of
                    $45,000 as required by the Purchase Agreement and to
                    eliminate Pyropower's equity accounts of $71,339 which
                    include the revaluation of investments of $6,500 made under
                    International Accounting Standards.

               (2)  To reflect the sources of the consideration paid for the
                    estimated purchase price of $200,000, plus estimated direct
                    costs of $10,000 to be incurred in consummating the
                    acquisition:

INDEPENDENT AUDITORS' REPORT

TO THE BOARD OF DIRECTORS OF A. AHLSTROM CORPORATION:

We have audited the accompanying combined statements of assets and liabilities
of Ahlstrom Pyropower representing the Power Generation Business of A. Ahlstrom
Corporation and its subsidiaries (as defined in Note 1 to the Combined Financial
Statements) as at December 31, 1994 and related combined statements of revenues
and expenses and cash flows for the year then ended. These combined financial
statements are the responsibility of A. Ahlstrom Corporation's management. Our
responsibility is to express an opinion on these combined financial statements
based on our audits. We did not audit the financial statements of Ahlstrom
Pyropower, Inc. and subsidiaries, an entity included in the combined financial
statements, which statements reflect total assets constituting 49 percent and
total revenues constituting 30 percent in 1994 of the related combined totals.
Those statements were audited by other auditors whose report has been furnished
to us, and our opinion, insofar as it relates to the amounts included for
Ahlstrom Pyropower, Inc. and subsidiaries, is based solely on the report of the
other auditors.

We conducted our audit in accordance with generally accepted auditing standards
in Finland and the United States. These standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit and the report of
the other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audit and the report of other auditors, the
combined financial statements referred to above present fairly, in all material
respects, the financial position of Ahlstrom Pyropower as at December 31, 1994
and the results of its operations and its cash flows for the year then ended in
conformity with International Accounting Standards.

International Accounting Standards vary in certain significant respects from
generally accepted accounting principles in the United States. A description of

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1.       Basis of Presentation

              Ahlstrom Pyropower (AP) develops and markets advanced combustion
              technology and related products for worldwide industrial and
              utility markets and specializes in power generation systems based
              on fluidized bed technology. AP presents the power generation
              sector of A. Ahlstrom Corporation (Ahlstrom) of Finland that is
              being sold to Foster Wheeler Corporation (FWC) pursuant to the
              Purchase Agreement, as defined below in Note 2.

              These financial statements present the combined financial
              position, results of operations and cash flows of AP in accordance
              with International Accounting Standards, as adopted by Ahlstrom.
              These financial statements have been prepared from the historical
              books and records of AP except that certain assets, obligations
              and liabilities that will not be assumed by FWC have been excluded
              from these financial statements. All debts to affiliated companies
              have been capitalized in accordance with the Purchase Agreement
              discussed in Note 2 and are included in the Net Investment of A.
              Ahlstrom Corporation. In addition, income tax expense was
              determined as if AP had filed a separate tax return.

              The Net Investment of A. Ahlstrom Corporation in the combined
              statement of assets and liabilities represents the difference
              between assets to be acquired and liabilities to be assumed by
              FWC.

              Based on the most recent information available to management as of
              the date of the issuance of these financial statements, October 5,
              1995, certain adjustments have been made to the net investment of
              A. Ahlstrom Corporation as of January 1, 1994 and to the results
              of operations for the year ended December 31, 1994, to reflect the
              latest profitability and loss estimates on individual contracts
              and related warranty reserve provision.

2.       Purchase Agreement

              On June 21, 1995 FWC entered into a Purchase Agreement (Agreement)
              with Ahlstrom. Under the terms of the Agreement, FWC will acquire
              the stock of certain subsidiaries of Ahlstrom and certain of AP's
              assets and assume certain liabilities as defined in the Agreement.

3.       Summary of Significant Accounting Policies

              The financial statements of AP have been prepared in connection
              with International Accounting Standards (IAS).

         Accounting convention

              The financial statements are presented in Finnish marks and are
              prepared under the historic cost convention except for
              revaluations of certain items included in noncurrent assets.

         Principles of combination

              The combined financial statements include the accounts of

                 Varkaus Boiler Works (part of A. Ahlstrom Corporation)
                 Hans Ahlstrom Laboratory (part of A. Ahlstrom Corporation)
                 Steka Oy, Finland
                 Bioflow Oy, Finland
                 Ahlstrom Pyropower Inc. and subsidiaries, USA
                 Ahlstrom Fakop Ltd., Poland
                 Ahlstrom Pyropower K.K., Japan
                 Ahlstrom Pyropower Europe B.V., The Netherlands

              The equity method of accounting is used to account for investments
              in associated companies in which AP has 20 to 50 percent of the
              voting shares. Shares in associated companies are revalued to
              their fair value with a corresponding increase to equity.

              The results of operations of companies acquired during the year
              are included in the financial statements from the date of
              acquisition, and companies that have been sold during the year are
              included up to the date of sale.

                               AHLSTROM PYROPOWER
                     NOTES TO COMBINED FINANCIAL STATEMENTS
                                   (CONTINUED)

              All significant intercompany accounts and transactions are
              eliminated in combination.

              Acquisitions are accounted for under the purchase method of
              accounting and accordingly, in each case, the purchase price is
              allocated to the assets acquired and the liabilities assumed based
              upon their estimated fair values at the date of acquisition. The
              excess of the fair value of the net assets acquired over the
              purchase price is recorded on the statement of assets and
              liabilities as negative goodwill. Negative goodwill is amortized
              on a straight-line basis over a maximum of 10 years.

         Revenue recognition

              Revenue from the sale of goods and services is recognized when the
              goods are delivered or the services are rendered.

              Revenue from construction contracts is recognized under the
              percentage of completion method.

              Net sales are shown net of returns, discounts and gains and losses
              on forward exchange contracts entered into for hedging of sales
              contracts. Other exchange gains and losses related to sales appear
              under the caption "Exchange losses."

         Losses and warranty claims for construction contracts

              Anticipated contract losses are recognized in full when they
              become known. Estimated warranty costs are charged to income at
              the time of completion of the contracts.

         Foreign currency translation

              Assets and liabilities that result from foreign currency
              transactions are restated at the exchange rates in effect at
              year-end. The resulting gains and losses are credited or charged
              to income.

              Foreign currency financial statements are translated into Finnish
              marks using exchange rates in effect at year-end. The effect of
              the adjustments arising from such translation is included in the
              Net Investment of A. Ahlstrom Corporation.

                                   (CONTINUED)

         Research and development costs

              Research and development costs are expensed as incurred. However,
              the costs of certain strategic development projects are
              capitalized and amortized over a maximum of ten years.

         Inventories

              Inventories are stated at the lower of cost or market, primarily
              on a first-in, first-out basis. The cost of inventories includes
              all direct costs as well as an allocation of production overheads.

         Property, plant and equipment

              Property, plant and equipment is carried at cost or in certain
              cases, revalued amounts, less accumulated depreciation.

              Depreciation is recorded using the straight-line method over the
              estimated useful lives of the assets within the following ranges:

<TABLE>
<S>                                                <C>
                 Buildings                         25 - 40 years
                 Heavy machinery                   10 - 20 years
                 Other machinery                    3 - 10 years
</TABLE>

         Intangible assets

              Intangible assets are amortized over a maximum of twenty years.

         Capitalization of interest costs

              Interest costs are capitalized as part of the acquisition costs of
              assets which are constructed for AP's own use.

         Taxes

              For AP's U.S. based companies, deferred taxes are provided for
              temporary differences between the book and tax basis of assets and
              liabilities in accordance with local practice. For AP's other
              companies, the deferred tax liability is recorded only if it is
              likely to crystallize or become payable in the foreseeable future.

                                   (CONTINUED)

         Corporate expenses

              Ahlstrom has charged AP for certain corporate administrative
              expenses. The charges were designed to reimburse Ahlstrom for
              management, financial and certain other services provided in
              accordance with Ahlstrom's corporate policies for allocation of
              such amounts.

4.       Summary of significant differences between IAS and U.S. GAAP

              The combined financial statements of AP have been prepared in
              accordance with International Accounting Standards (IAS). IAS
              differ in certain respects from U.S. GAAP. A summary of such
              differences, as they relate to AP, follows.

         Research and development costs

              AP capitalizes the costs of certain strategic development
              projects, which are amortized over a maximum of ten years.

              U.S. GAAP requires that research and development costs be expensed
              as incurred.

         Translation of foreign subsidiaries financial statements

              In the combined financial statements of AP, the assets and
              liabilities and the revenue and expense accounts of the foreign
              entities are translated from the entities' foreign currency into
              Finnish marks using the exchange rates prevailing at the end of
              each period.

              Under U.S. GAAP, the profit and loss accounts of foreign
              subsidiaries would be translated to Finnish marks at the average
              exchange rates prevailing during the year. Differences arising on
              translation would also be recorded directly to net investment of
              A. Ahlstrom Corporation.

         Revaluation of land and buildings

              IAS provides the opportunity to revalue property, plant and
              equipment to its fair value with a corresponding increase to
              equity. Depreciation is based upon the revalued basis of the
              assets acquired.


<PAGE>   22



                               AHLSTROM PYROPOWER
                     NOTES TO COMBINED FINANCIAL STATEMENTS
                                   (CONTINUED)

              Under U.S. GAAP, revaluation of fixed assets is not allowed and
              depreciation is based upon the historical cost basis of the assets
              acquired.

         Deferred income taxes

              Under IAS, the company records a liability for deferred income
              taxes for timing differences to the extent that it is likely to
              reverse or crystallize in the foreseeable future, except for U.S.
              operations which are recorded in accordance with U.S. GAAP.

              U.S. GAAP requires that deferred taxes be established on all
              differences between the book basis and the tax basis of assets and
              liabilities (i.e., temporary differences) regardless of the
              likelihood of reversal or crystallization. U.S. GAAP allows
              deferred tax assets to be established for all temporary
              differences which will be future tax deductions and tax loss carry
              forwards, to the extent that it is "more likely than not" that AP
              will realize a tax benefit.

         Acquisitions

              AP uses the purchase method to account for the acquisition of a
              business. In certain cases, the fair value of the net assets
              acquired may exceed the purchase price (i.e., "negative good
              will"). AP amortizes negative goodwill as income in the revenue
              and expense accounts.

              Under U.S. GAAP, negative goodwill is required to be first applied
              to reduce the carrying value of acquired long-term tangible and
              identifiable intangible assets. Any remaining negative goodwill is
              then recorded as a deferred credit in the statement of assets and
              liabilities and amortized to income in the revenue and expense
              accounts over its estimated useful life.

         Revaluation of shares and equity investments

              IAS provides the opportunity to revalue shares in associated
              companies accounted for by the equity method to its fair value
              with a corresponding increase to equity.

              Under U.S. GAAP, revaluation of shares and equity investments is
              not allowed.

                                   (CONTINUED)

         Pensions

              AP has various pension schemes in subsidiaries as required by
              local conditions and practices of the countries in which they
              operate. AP's policy for funding its pension plans is to satisfy
              local statutory funding requirements for tax deductible
              contributions. These contributions are charged against profits.

              Accounting for pension costs under U.S. GAAP is governed by SFAS
              No. 87, "Employers' Accounting for Pensions." SFAS No. 87 is more
              prescriptive, particularly as to the use of actuarial assumptions,
              and requires that a specific actuarial method, the projected unit
              cost method, be used.

5.       Minority interests

              The minority interest benefit in the statement of revenues and
              expenses is the result of losses being incurred primarily by the
              Polish company of AP, which is 49.11% owned by minority
              shareholders.

6.       Subsequent events

         In connection with the acquisition of Ahlstrom Pyropower by Foster
         Wheeler Corporation (see Note 2), certain adjustments were made to the
         assets and to the liabilities of AP, including additional provisions
         for possible future warranty liabilities and certain contingencies. In
         management's opinion, it is not appropriate that these adjustments be
         reflected in the financial statements as of December 31, 1994.

                                      -23-

itself or any Affiliate) to obtain, or cause to be obtained in writing, prior
to the Closing Date, any  consents necessary to convey the benefit thereof.
Purchasers shall cooperate with Seller, in such manner as may be reasonably
requested (but at no material cost or expense to any Purchaser) in connection
therewith, including, without limitation, active participation in visits to and
meetings, discussions and negotiations with all Persons with the authority to
grant or withhold consent.  Nothing in this Agreement shall be construed as an
attempt or an agreement to assign or cause the assignment of any Assigned
Contract or any contracts to which a Subject Company is a party as of the
Closing (i) which is by law nonassignable or otherwise nontransferable without
the consent of the other party or parties thereto, unless such consent shall
have been given, or (ii) as to which all the remedies for the enforcement
thereof enjoyed by Seller or any of its Affiliates would not, as a matter of
law, pass as an incident of the assignments or other transfers provided by this
Agreement.  In those cases where consents have not been obtained to the sale,
conveyance, assignment or delivery to Purchasers of any Assigned Contract or
contract requiring consent in connection with the sale of the Stock to which a
Subject Company is a party as of the Closing (collectively, "Non-Conveyed
Contracts"), Seller shall, promptly following FW's written request, take all
commercially reasonable steps and actions to provide Purchasers with the
benefit of such Non-Conveyed Contracts (including, but not limited to, (i)
enforcing, at the request and expense of Purchasers, any rights of Seller
arising with respect thereto (including, without limitation, the right to
terminate in accordance with the terms thereof upon the advice of Purchasers)
or (ii) permitting Purchasers to enforce any rights arising with respect
thereto) as if such Non-Conveyed Contracts had been sold, conveyed, assigned
and delivered to Purchasers; provided, however, that Purchasers shall use
commercially reasonable efforts (but at no material cost or expense to
themselves) to enter into novation agreements to remove Seller from all
obligations or liabilities under such Non-Conveyed Contracts if, and only to
the extent that, such Purchaser has entered into a contract directly with the
other party to the Non-Conveyed Contract with respect to the subject matter
thereof.  The provisions of this Section 2.5 shall not affect the right of
Purchasers not to consummate the transactions contemplated by this Agreement if
the conditions to their obligations hereunder contained in Sections 7.5 and
7.11 have not been otherwise fulfilled.

                 2.6.  Instruments of Transfer and Conveyance.  (a) The sale,
conveyance, transfer, assignment and delivery of the Assets shall be effected
by delivery on the Closing Date by (i) Seller, ADC or any other Affiliate of
Seller, as applicable, to a Purchaser of such deeds in proper form for
recordation, transfers in registrable form, bills of sale in registrable form,
endorsements, assurances, conveyances, releases, discharges, assignments,
certificates or other instruments of transfer and conveyance, duly executed by
Seller or an Affiliate of Seller, as applicable, as FW shall deem necessary to
vest in a Purchaser, good title to such Assets free and clear of any
Encumbrance except Permitted Encumbrances, and such other documents as FW may
reasonably request to demonstrate satisfaction of the conditions and compliance
with this Agreement by Seller; and (ii) Purchasers to Seller of assumption
agreements providing for the full assumption of the Assumed Obligations in form
and substance reasonably satisfactory to Seller, and such other documents as
Seller may reasonably request to demonstrate satisfaction of the conditions and
compliance with this Agreement by Purchasers.

                 2.7.  Closing.  Subject to the terms and conditions of this
Agreement, the purchase and sale of (a) the Stock and the ADC Assets pursuant
to this Agreement shall take place at the offices of White & Case, 1155 Avenue
of the Americas, New York, New York 10036 at 10:00 A.M. New York time, and (b)
the Finland Assets pursuant to this Agreement shall take place at the offices
of White & Case Oy, Etelaranta 14, FIN-00130, Helsinki, Finland, at 5:00 P.M.
Helsinki time, in each case, if the Antitrust Clearance Date occurred, within
five (5) Business Days after delivery of written notice by FW to Seller;
provided, however, that in no event shall (x) the Closing occur later than
November 30, 1995 (such date to be extended as required for the parties to
satisfy the conditions set forth in Sections 6.4, 7.4, 7.5, 7.8 and 7.11 but in
no event beyond December 29, 1995) and (y) the Closing occur prior to September
1, 1995 without the prior written consent of Seller and FW.  The consummation
of the purchases and sales described in clauses (a) and (b) of this Section 2.7
are hereinafter referred to collectively as the "Closing."  Such time and date
of the Closing are herein referred to as the "Closing Date."

                          (C)     the amount, if any, by which cash and cash

                 the earlier to occur of (x) the Closing Date and (y) the last
                 Business Day of the month in which the Cash Guaranty Date
                 occurs,

                          (D)     the amount, if any, by which the aggregate
                 amount of Contribution I is or was less than the Guaranteed
                 Contribution I Amount on the earlier to occur of (x) the
                 Closing Date and (y) the last Business Day of the month in
                 which the Contribution I Determination Date occurs,





                                      -26-
<PAGE>   37




                          (E)     the aggregate US dollar amount, if any, of
                 Contribution I attributable to all Non-Conveyed Contracts, the
                 benefits of which have not been provided to a Purchaser
                 pursuant to Section 2.5,

                          (F)     the US dollar amount, if any, by which
                 Indebtedness of the Power Generation Business set forth on the
                 Current Monthly Balance Sheet exceeds Permitted Indebtedness,

                          (G)     the Holdback Amount; and

                          (H)  if the events described in Section 8.19(c) have 
                 occurred, the amount of the Bioflow Price.

                 3.2.  Post Closing Adjustments.

                 (a)  Preparation of Preliminary Closing Balance Sheet.  As
soon as reasonably possible after the Closing Date (but not later than ninety
(90) days thereafter), FW will prepare a combined balance sheet, together with
combining statements (the "Preliminary Closing Balance Sheet") of the Power
Generation Business as at the Closing Date, and shall deliver the Preliminary
Closing Balance Sheet to Seller together with the report thereon of Coopers &
Lybrand L.L.P. ("FW's Accountants").  The Preliminary Closing Balance Sheet
shall be prepared in accordance with International Accounting Standards
Consistently Applied and, with respect to work in progress and other items
related to Backlog, consistent with Section 3.7 and reviewed by FW's
Accountants.  Seller shall have the right to attend and participate in meetings
of FW's working group in connection with the preparation of the Preliminary
Closing Balance Sheet and (together with its accountants) to participate in
meetings with FW's Accountants with respect thereto.

                 The Preliminary Closing Balance Sheet shall also include a
schedule indicating the calculation of the Net Worth and the Closing Working
Capital Deficiency, if any, of the Power Generation Business as of the Closing
Date.  Notwithstanding anything to the contrary set forth in this Agreement,
neither the Preliminary Closing Balance Sheet nor the Final Closing Balance
Sheet shall include or reflect the Retained Shared Assets.

                 (b)  Review of Preliminary Closing Balance Sheet.  The
Preliminary Closing Balance Sheet shall be binding and conclusive upon, and
deemed accepted by Seller unless Seller





                                      -27-
<PAGE>   38




shall have notified FW in writing of any objections thereto within sixty (60)
days after receipt thereof.  The written notice under this Section 3.2(b) shall
specify in reasonable detail each item on the Preliminary Closing Balance Sheet
that Seller disputes and a summary of its reasons for such dispute.  FW shall
allow Seller and any agent of Seller, upon reasonable advance notice to FW,
supervised access to all Books and Records, accountant's work papers, personnel
and all other documents reasonably necessary in connection with its review of
the Preliminary Closing Balance Sheet, during normal working hours at
Purchasers' principal places of business or at any location where such
materials are located, and Seller and any agent of Seller shall have the right,
at its cost, to make copies of any such materials.  In addition, FW shall
authorize and instruct FW's Accountants to cooperate with and provide all
assistance reasonably deemed necessary by Seller and Seller's accountants in
connection with the review of the Preliminary Closing Balance Sheet, and Seller
and Seller's accountants shall be entitled to carry out such additional
inquiries as they reasonably consider appropriate in that connection, including
access to the working papers prepared by FW's Accountants with respect to the
Preliminary Closing Balance Sheet.

                 (c)  Disputes.  Disputes between Seller and FW relating to the
Preliminary Closing Balance Sheet that cannot be resolved by them within thirty
(30) days after receipt by FW of the notice referred to in Section 3.2(b) may
be referred thereafter for decision at the request of Seller or FW to Ernst &
Young or such other independent accounting firm acceptable to Seller and FW
(such firm being referred to herein as the "Auditor").  Upon a request to refer
the matter to the Auditor, the parties shall use their best efforts to agree on
the procedures to be followed by the Auditor (including procedures with regard
to presentation of evidence) within thirty (30) days following such request.
Such procedures shall not alter the accounting practices, principles and
policies to be applied to the Preliminary Closing Balance Sheet which will be
those required by this Agreement.  The Auditor shall review only items in
dispute.  If the parties are unable to agree upon procedures at the end of the
thirty (30) day period referred to above, the Auditor shall establish such
procedures giving due regard to the intention of the parties to resolve
disputes as quickly, efficiently and inexpensively as possible, which
procedures may be, but need not be, those proposed by either party.  The
parties shall then submit evidence in accordance with the procedures
established, and the Auditor shall decide the dispute in accordance therewith.
The Auditor's decision on any mat-





                                      -28-
<PAGE>   39




ter referred to it shall be final and binding on Seller and Purchasers.  The
fee of the Auditor shall be borne equally by Seller and FW.

                 (d)  Final Closing Balance Sheet.  The Preliminary Closing
Balance Sheet shall become final and binding upon the parties upon the earliest
of (i) the failure by Seller to object thereto within the period permitted
under Section 3.2(b), (ii) the agreement between FW and Seller with respect
thereto and (iii) the decision by the Auditor with respect to any disputes
under Section 3.2(c).  The Preliminary Closing Balance Sheet, when final and
binding in accordance with the immediately preceding sentence, is referred to
herein as the "Final Closing Balance Sheet."

                 (e)  Adjustment to the Purchase Price.  (i)  As soon as
practicable (but not more than five (5) Business Days) after the determination
of the Final Closing Balance Sheet in accordance with Section 3.2(d), a
determination shall be made of the amount, if any, by which the Closing Payment
was greater or less than the amount equal to the aggregate of the following
based on the Final Closing Balance Sheet (the "Adjusted Closing Payment"):  (A)
$195,000,000 plus the Closing Bookings Payment minus (B) each of the following:

                          (1)     the Closing Working Capital Deficiency, if 
                 any;

                          (2)     the Closing Net Worth Deficiency, if any;

                          (3)     the amount, if any, by which cash and cash
                 equivalents is or was less than the Guaranteed Cash Amount on
                 the earlier to occur of (x) the Closing Date and (y) the last
                 Business Day of the month in which the Cash Guaranty Date
                 occurs;

                          (4)     the amount, if any, by which the aggregate
                 amount of Contribution I is or was less than the Guaranteed
                 Contribution I Amount on the earlier to occur of (x) the
                 Closing Date and (y) the last Business Day of the month in
                 which the Contribution I Determination Date occurs;

                          (5)  the aggregate US dollar amount of Contribution
                 I, if any, attributable to Non-Conveyed Contracts, the
                 benefits of which have not





                                      -29-
<PAGE>   40




                 been provided to a Purchaser pursuant to Section 2.5;

                          (6)     the US dollar amount, if any, by which
                 Indebtedness of the Power Generation Business set forth on the
                 Final Closing Balance Sheet exceeds Permitted Indebtedness;
                 and

                          (7)  if the events described in Section 8.19(c) have
                               occurred, the amount of the Bioflow Price.

                 (ii)  (A)  If the Closing Payment exceeds the Adjusted Closing
Payment, then Seller shall pay FW an amount equal to the Closing Payment minus
the Adjusted Closing Payment.  (B)  If the Adjusted Closing Payment exceeds the
Closing Payment, then FW shall pay Seller an amount equal to the amount of such
excess less any portion of the Holdback Amount which FW is entitled to retain
pursuant to clause (f) below.

                 (f)      Category II Representations and Warranties.  At the
Closing, Seller shall deliver to FW a certificate of an authorized officer of
Seller, dated the Closing Date, to the effect that the Category II
Representations and Warranties as supplemented, if applicable, pursuant to
Section 8.21 are true and correct in all material respects as of the Closing
Date (to the extent any such representation and warranty is not already
qualified by materiality).  If the Category II Representations and Warranties
as supplemented, if applicable, pursuant to Section 8.21 are not true and
correct in all material respects as of the Closing Date (to the extent any such
representation and warranty is not already qualified by materiality) on the
Closing Date, FW shall have the right to notify Seller thereof by delivering to
Seller on the Closing Date the Certificate required by Section 13.3(a) and
retain a portion of the Holdback Amount equal to the amount of all Losses that
FW has incurred or reasonably believes it will incur or suffer arising out of
the breach of any such representations and warranties until such time as it is
determined whether or not FW is entitled to be indemnified by Seller under
Section 13.2(a)(i) for the Losses specified in FW's Certificate and the amount
thereof.  For purposes of determining whether FW is entitled to be indemnified
by Seller under Section 13.2(a)(i) by reason of the breach of the Category II
Representations and Warranties as of the Closing, FW shall be entitled to be
indemnified by Seller from the first dollar of Losses incurred.  FW shall pay
to Seller the amount of the Holdback Amount less any





                                      -30-
<PAGE>   41




amounts required to be paid to FW under Section 13.2(a)(i) by reason of this
clause (f).  In addition, after the determination as to whether or not FW is
entitled to be indemnified by Seller for any of the items of Loss specified in
the Certificate, FW shall pay to Seller any portion of the Holdback Amount
retained in respect of such item that is not required to be paid to FW.
Notwithstanding the foregoing, if at any time FW is required to pay all or any
portion of the Holdback Amount to Seller under this clause (f), FW shall be
entitled to retain the Holdback Amount until the Preliminary Closing Balance
Sheet becomes final in accordance with Section 3.2(d).

                 (g)      Amounts not in Dispute.  Notwithstanding anything to
the contrary contained in this Section 3.2, pending resolution of all disputed
items with respect to the Preliminary Closing Balance Sheet, the amount of any
adjustment to the Purchase Price that is not in dispute shall be paid (i) in
the case of any amounts to which Seller has not objected pursuant to Section
3.2(b), upon the earlier of (A) sixty (60) days after receipt by Seller of the
Preliminary Closing Balance Sheet and (B) the date on which Seller shall have
notified FW in writing of any objections thereto and indicated that, except as
so stated, it has no further objections and (ii) in the case of any disputed
amount or portions thereof, upon resolution of any dispute with respect to such
amounts or portions.  Any payment required by this Section 3.2 shall not limit
or affect Purchasers' rights or remedies (or be Purchasers' sole or exclusive
right or remedy) with respect to this Agreement or any agreement delivered in
connection herewith, or the breach of any representation, warranty or
obligation of Seller herein.

                 (h)      Interest.  Amounts required to be paid pursuant to
Sections 3.2(e), 3.2(f), 3.2(g), 3.3, 3.4 and 3.5 shall be paid by wire
transfer in immediately available funds to an account or accounts designated in
writing by FW (in the case of payments due to FW) or Seller (in the case of
payments due to Seller) and such amounts shall be paid together with interest
thereon at the rate of interest printed in the Money Rates section of the then
current eastern edition of the WALL STREET JOURNAL as the "PRIME RATE" (the
"U.S. Prime Rate") and accruing from the Closing Date to the date of payment.

                 3.3.  Working Capital Repayment.  As soon as practicable (but
not more than five (5) Business Days) after the determination of the Final
Closing Balance Sheet in accordance with Section 3.2(d), FW shall pay to Seller
the





                                      -31-
<PAGE>   42




amount, if any, by which (i) the current liabilities of the Power Generation
Business set forth on the Final Closing Balance Sheet minus current assets of
the Power Generation Business set forth on the Final Closing Balance Sheet is
less than (ii) four million five hundred thousand US dollars ($4,500,000) (the
"Working Capital Difference"); provided, however, that FW shall only be
required to pay that portion of the Working Capital Difference which (1) when
deducted from the cash and cash equivalents on the Final Closing Balance Sheet
leaves a balance of cash and cash equivalents that equals or exceeds the
Guaranteed Cash Amount (if the date of the Final Closing Balance Sheet is on or
prior to the Cash Guaranty Date) and (2) when deducted from the Net Worth
reflected on the Final Closing Balance Sheet results in a Net Worth that is
equal to or greater than forty-three million US dollars ($43,000,000).

                 3.4.  1995 Bookings.  As used herein, the term "Closing
Bookings Payment" shall mean an amount equal to the Bookings Payment on all
Bookings during the period commencing on January 1, 1995 and ending on (and
including) the last day of the month preceding the Closing Date (the "Closing
Bookings Payment").  Schedule 3.4(a) reflects Seller's best estimate of a list
of all Bookings during the period commencing on January 1, 1995 and ending on
May 31, 1995.  As soon as practicable after the date hereof, Seller shall
deliver to FW a replacement schedule reflecting the project name, date of
contract and contract price containing a list of all Bookings during the period
commencing on (and including) January 1, 1995 and ending on May 31, 1995.
Seller agrees to deliver to FW not less than three (3) Business Days prior to
the Closing a supplement to such replacement Schedule reflecting all Bookings
during the period commencing on (and including) June 1, 1995 and ending on (and
including) the last day of the month preceding the Closing Date.  On February
1, 1996, Purchasers shall pay to Seller, by wire transfer in immediately
available funds, an amount equal to the Bookings Payment on all Bookings (which
may have been entered into by any Purchaser or any Affiliate of a Purchaser as
well as by a Subject Company) (a) during the period commencing on (and
including) the first day of the month in which the Closing Date occurs and
ending on and including December 31, 1995 ("Post-Closing Bookings Payment")
resulting from bids and proposals set forth on Schedule 4.37(b) attached hereto
as supplemented at or prior to the Closing Date.  The sum of the Closing
Bookings Payment and the Post-Closing Bookings Payment shall in no event exceed
thirty-five million US dollars ($35,000,000).





                                      -32-
<PAGE>   43




                 3.5.  POSCO Payment.  On February 1, 1996, FW shall pay to
Seller the sum of (a) eight (8%) percent of the profits before taxes earned
under the POSCO Contracts during the period of January 1, 1995 through December
31, 1995 plus (b) an amount equal to the POSCO Bonus Payment.  In the event
that any bonuses are paid to POSCO under POSCO Contracts after February 1,
1996, FW shall pay to Seller the pro rata portion of such bonus (determined in
accordance with the definition of POSCO Bonus Payment) within five (5) Business
Days after receipt thereof.  Notwithstanding the foregoing, the POSCO Payment
shall not exceed an amount equal to the amount which when added to the sum of
the Closing Bookings Payment and the Post-Closing Bookings Payment, equals
thirty-five million US dollars ($35,000,000).

                 3.6.  Allocation of Purchase Price.  Purchasers and Seller
will agree prior to the Closing, acting reasonably and in good faith, on an
allocation of the Purchase Price and Assumed Obligations among the Assets and
the Purchased Companies.  Such allocation shall be adjusted in the manner
agreed by Purchasers and Seller to reflect adjustments to the Purchase Price
and Assumed Obligations made in accordance with this Agreement.

                 3.7.  Opening Backlog.  FW and Seller agree that,
notwithstanding anything to the contrary in this Agreement or provided by
International Accounting Standards Consistently Applied, the Opening Backlog
and the most recent project budgets as of the date of this Agreement for each
of the subject projects, as revised in accordance with the contract review
procedures outlined in Section 8.20 (as so revised, the "Project Budgets"),
shall be, with respect to the subject projects, the basis for all calculations
relating to Contribution I and the Backlog for purposes of this Agreement,
whether at the time of or subsequent to the Closing, including, but not limited
to, the preparation of the Preliminary Closing Balance Sheet and the Final
Closing Balance Sheet and all calculations based thereon; provided, however,
that the Contribution I Margin and estimated reserves reflected in the Opening
Backlog may be adjusted to reflect (i) errors in calculation (e.g.,
mathematical errors) or omissions in scope and (ii) the effects of objective
events or developments subsequent to the dates of the respective Project
Budgets that, subject to Section 8.20, in the good faith determination of
Seller made in accordance with its past project budgeting practices, require
adjustments to or application of contingencies or reserves in the Project
Budgets.

         Business as at December 31, 1994 (the "Balance Sheet") and the related
         combined and combining statements of income for the year then ended
         (the "Income Statement") together with the report thereon of KPMG
         WIDERI OY AB.  Seller has heretofore furnished FW statements of cash
         flows for the Power Generation Business for the period ending December
         31, 1994 (the "Cash Flow Statements") (together with the Balance Sheet
         and the Income Statement, the "Financial Statements").  The Balance
         Sheet and the Income Statement, except as indicated therein, have been
         prepared in accordance with International Accounting Standards
         Consistently Applied.  The Cash Flow Statements have been prepared
         from the books and records of Seller on a basis consistent with
         Seller's internal management accounting presentations.  The Balance
         Sheet and the Income Statement fairly present in all material respects
         the financial position of the Power Generation Business and the
         results of operations for the period indicated except for the
         exclusion of the ADC Assets.

                 (ii)  Since December 31, 1994 (the "Balance Sheet 
         Date"), there has been no Material Adverse Effect, or a Material
         Adverse Effect (other than with respect to prospects) on any of
         Ahlstrom Boilers, AF or API.

                 (iii) Since the Balance Sheet Date, except as set
         forth in Schedule 4.5(a)(ii) attached hereto, Seller and each Subject
         Company have conducted the Power Generation Business only in the
         ordinary course and in a manner consistent in all material respects
         with prior business practices.  Schedule 4.5(a)(iii) attached hereto
         sets





                                      -37-
<PAGE>   48




         forth an accurate explanation of the net loss incurred by Ahlstrom
         Boilers for the period discussed therein.

                 (b)  Attached hereto as Schedule 4.5(b) are unaudited combined
and combining balance sheets of the Power Generation Business as at April 30,
1995 (the "Interim Balance Sheet") and the related combined and combining
statements of income (the "Interim Income Statement") for the periods then
ended.  Seller has heretofore furnished FW with statements of cash flows for
the periods ended February, March, April and May, 1995 (the "Interim Cash Flow
Statement") (together with the Interim Balance Sheet and the Interim Income
Statement, the "Interim Financial Statements").  The Interim Balance Sheet and
the Interim Income Statement except as indicated therein, have been prepared in
accordance with International Accounting Standards Consistently Applied.  The
Interim Cash Flow Statement has been prepared from the Books and Records of
Seller on a basis consistent with Seller's internal management accounting
presentations.  The Interim Financial Statements fairly present in all material
respects the financial position of the Power Generation Business and the
results of operations and cash flows for the periods indicated.

                 (c)  The Seller Accounting Manual attached hereto as Schedule
4.5(c) sets forth the principal elements of International Accounting Standards
as adopted by Seller and applied in the preparation of its financial reports,
including the Financial Statements and the Interim Financial Statements.

                 (d)  The 1994 Three Year Plan of the Power Generation Business
attached hereto as Schedule 4.5(d) (the "1994 Three Year Plan") was prepared by
Seller for its internal management purposes in the ordinary course of business
in accordance with past practice and, insofar as the 1994 Three Year Plan sets
forth revenue and profit targets for the periods covered thereby, such targets,
and the assumptions on which they were based were in the judgment of Seller not
unreasonable in light of market and industry conditions existing at the time
the 1994 Three Year Plan was prepared.

                 (e)  The 1995 Budget of the Power Generation Business attached
hereto as Schedule 4.5(e) (the "1995 Budget") was prepared by Seller for its
internal management purposes in the ordinary course of business in accordance
with past practice and, insofar as the 1995 Budget sets forth





                                      -38-
<PAGE>   49




revenue and profit estimates for the period covered thereby, such estimates and
the assumptions on which they were based were, in the judgment of Seller, not
unreasonable in light of market and industry conditions existing at the time

any Subject Company in respect of personal injury, wrongful death or property
damage alleged to have resulted from products or services provided by Seller

together with a description of the disposition thereof.  Schedule 4.6(a)(i)
also sets forth any written finding or statement (of which a copy or statement
was furnished, directly or indirectly, to Seller) during the past three (3)
years with respect to the safety of the products or services provided by Seller
(in respect of the Power Generation Business) or any Subject Company except as
listed in Schedule 4.13.

                 (ii)  Schedule 4.6(a)(ii) attached hereto sets forth all
         losses in respect of workers' compensation claims, if any, as a
         percentage of aggregate net revenues of each Subject Company in the
         United States of America.  Schedule 4.6(a)(ii) also sets forth the
         premiums paid for workers' compensation insurance as a percentage of
         wages and salaries for Seller and Steka for each of the last three
         years.

                 (iii)  Schedule 4.6(a)(iii) attached hereto sets forth

         Generation Business) for each of the periods set forth therein.

         Balance Sheet have been established on a basis consistent with past

         its Affiliates.

Subject Companies.  Except as set forth in Schedule 4.7 attached hereto, no
Subject Company has any of its records, systems, controls, data or information
recorded, stored, maintained, operated or otherwise wholly or partly dependent
upon or held by any means (including any electronic, mechanical or photographic
process, whether computerized or not) which (including all means of access
thereto and therefrom) are not under the exclusive ownership and direct control
of such Subject Company.

                 4.8.  Title to Properties; Encumbrances; Condition.  Except as
set forth in Schedule 4.8 attached hereto and except for properties and assets
reflected in the Financial Statements or acquired since the Balance Sheet Date
which have been sold or otherwise disposed of in the ordinary course of
business, Seller and each Subject Company has good and valid title or right of
perpetual usufruct (or leasehold interest with respect to leased assets) to
each of its respective assets relating to the Power Generation Business (real
and personal, tangible and intangible), including, without limitation, each of
such assets (a) reflected in the Financial Statements and (b) purchased by
Seller or such Subject Company since the Balance Sheet Date; in each case
subject to no Encumbrance of any kind except as set forth on Schedule 4.8 and
for (i) Encumbrances which do not materially detract from the value of, or
materially impair the use of, such assets by Seller or such Subject Company in
the operation of the Power Generation Business, and (ii) Encumbrances for
current taxes, assessments or governmental charges or levies or mechanic's
liens on property not yet delinquent except that this representation does not
relate to any Acquired Intellectual Property (title to and Encumbrances on such
Intellectual Property being covered by Section 4.17) (liens of the type
described in clauses (i) and (ii) above are hereinafter sometimes referred to
as "Permitted Encumbrances").  Within 45 days after the date of this Agreement,
Seller shall furnish FW with a fixed asset ledger which sets forth all fixed
assets having a book value in excess of $100,000 relating to the Power
Generation Business owned by Seller or any Subject Company as of May 31, 1995,
the location of such assets and the owner thereof.  Except as such ledgers
shall set forth, Seller or a Subject Company directly owns each of the fixed
assets set forth therein.  Each such asset that is currently in use as of the
date of this Agreement is in good operating condition and repair subject only
to ordinary wear and tear (but with respect to such assets located in
Sosnowiec, Poland, such representation is to the extent they are adequate for
completion of the Turow Contract without incurring capital expenditures in
excess of





                                      -40-
<PAGE>   51




the currently budgeted amounts set forth in Schedule 4.31), to the extent
required by any continuing manufacturer's warranty has been maintained in
accordance with the manufacturer's specifications in all material respects and
is substantially fit for the purposes for which it is being utilized.

                 4.9.  Real Property.  Schedule 4.9 attached hereto contains an
accurate and complete list of all real property owned in whole or in part or
held in perpetual usufruct by (a) Seller which is used exclusively in
connection with the Power Generation Business, and (b) any Subject Company (the
"Real Property") and identifies a list of all indebtedness secured by a lien,
mortgage or deed of trust thereon, and the general nature of the activities
conducted on such property.  Except as set forth in Schedule 4.9, all of the
buildings, structures and appurtenances situated on the Real Property that are
material to the operations carried out on such Real Property are in good
operating condition and in a state of good maintenance and repair subject to
ordinary wear and tear (but with respect to such assets located in Sosnowiec,
Poland, such representation is to the extent they are adequate for completion
of the Turow Contract without incurring capital expenditures in excess of the
currently budgeted amounts set forth in Schedule 4.31), are suitable for the
purposes for which they are presently being used and, with respect to each,
Seller or Subject Company has (and will, with respect to the Finland Assets,
convey to FW on the Closing Date) adequate rights of ingress and egress for
operation of the Power Generation Business in the ordinary course consistent
with past practice.  There is no real property owned by Seller or any of its
Affiliates (including the Subject Companies) used primarily in connection with
the Power Generation Business other than as set forth in Schedule 4.9 and other
than Retained Shared Assets.  None of such buildings, structures or
appurtenances (or any equipment therein), nor the operation or maintenance
thereof, violates any restrictive covenant or is subject to any Encumbrance
(other than Permitted Encumbrances) which, in each case, would preclude or
impair, in any material respect, the use of such property by Seller or a
Subject Company for the purposes for which it is currently used, or which
encroaches in any material respect on any property owned by others.  No
condemnation, expropriation, eminent domain or similar proceeding is pending or
to the best knowledge of Seller or any Subject Company, threatened, which would
preclude or impair the use of any such property, in any material respect, by
Seller or any Subject Company for the purposes for which it is currently used.

a party (as lessee or lessor) and relate exclusively to the operation of the
Power Generation Business and (b) any Subject Company is a party (as lessee or
lessor) (collectively, the "Leases").  There are no leases to which Seller or
any of its Affiliates (including the Subject Companies) is a party for property
used primarily in connection with the Power Generation Business other than as
set forth in Schedule 4.10, Schedule 4.11(a) or Schedule 4.32.  Each Lease set
forth in Schedule 4.10 (or required to be set forth in Schedule 4.10) is in
full force and effect and there exists no material default or material event of
default or event, occurrence, condition or act (including the purchase of the
Stock or the Assets hereunder) which, with the giving of notice, the lapse of
time or the happening of any other event or condition, would become a material
default or material event of default thereunder.

expenditures that is individually in excess of $100,000,

                 (e)  any loan or advance to, or investment in, any Person in
excess of $100,000 or any agreement, contract or

materials and supplies entered into in the ordinary course of business or
referred to in clauses (a) through (h) above and clauses (j) through (p) below
or in Section 4.17) which involves $100,000 or more and is not cancelable
without penalty within thirty (30) days, or the termination of which would
require a payment by Seller, in respect of the Power Generation Business, or
any Subject Company of $100,000 or more,

under which there are warranty obligations which have not expired, in each case

expressly excluded (other than for gross negligence and willful misconduct) and
any bid or proposal relating to the Power Generation Business which does not
contemplate an





                                      -43-
<PAGE>   54




express exclusion or written waiver of a potential customer's right to

required to be set forth in Schedule 4.11(a) through 4.11(p) or would be
required to be set forth in Schedule 4.11(j) without reference to any minimum
dollar amount), except as noted in such Schedules 4.11(a) through 4.11(p) is in
full force and effect and there exists no material default or material event of
default or event, occurrence, condition or act (including the purchase of the
Stock or the Assets hereunder) which, with the giving of notice, the lapse of
time or the happening of any other event or condition, would become a material
default or material event of default thereunder, it being agreed that default

disclosure to Purchasers or their advisors shall not constitute a material
default hereunder.

                 4.12.  Permits.  Except as set forth in Schedule 4.12 attached
hereto and except as may result from any facts or circumstances relating solely
to FW or its Affiliates, Seller or a Subject Company currently holds or is

(collectively "Permits") required in connection with the use, operation or
ownership of the Assets, the assets of the Subject Companies, and the conduct

limitation, Permits issued under Environmental Law, except for those the
absence of which would not materially adversely affect the operation of any
Subject Company or Ahlstrom Boilers by Purchasers after the Closing Date in the
ordinary course consistent with past practice.  Any applications for the
renewal of any such Permit due prior to the Closing Date have been, or will be,
timely filed prior to the Closing Date.  Except as set forth in Schedule 4.12,
no proceeding to modify, suspend, revoke,

withdraw, terminate or otherwise limit any such Permit is pending or, to the

of its Affiliates (in respect of the Power Generation Business), ADC (in
respect of the ADC Assets) or any Subject Company; and neither Seller, ADC, nor
any Subject Company knows of any valid basis for any such action, proceeding or

nor any Subject Company is subject to any judgment, order or decree entered in
any lawsuit or proceeding or settlement with respect thereto which could have a
material adverse effect on the ability of Purchasers to (i) acquire any
property which is material to the conduct of the Power Generation Business as
presently conducted or (ii) conduct business in any country in which the Power
Generation Business is currently conducted.  Schedule 4.13 lists all agreements
entered into in the two (2) years prior to the date hereof in connection with
the settlement of any Litigation against or affecting the properties (including
the Assets) or rights of Seller (in respect of the Power Generation Business)
or any Subject Company.

statements, forms and reports for Taxes ("Returns") that are required to be
filed by, or with respect to, the Subject Companies, the Finland Assets and the
ADC Assets on or prior to the Closing Date.  The Returns have accurately

respect to the Subject Companies, the Finland Assets and the ADC Assets for the
periods covered thereby.

                 (b)       Payment of Taxes.  All Taxes and Tax liabilities of
the Subject Companies or for which the Subject Companies may be liable and all
Taxes and Tax liabilities which may be asserted against the Finland Assets or
the ADC Assets for all taxable years or other taxable periods (including
portions thereof) prior to the Closing Date have been timely paid or accrued
and adequately disclosed and fully provided for as a liability on the Balance
Sheets in accordance with generally accepted accounting principles.

                 (c)       Other Tax Matters.  (i)  Schedule 4.14(c)(i)
attached hereto sets forth (A) each taxable year or other taxable period of

conducting (or scheduled to conduct) such audits or examinations and a
description of the subject matter of such audits or examinations, (B) the most
recent taxable year or other taxable period for which an audit or other

the Subject Companies which will not be subject to the normally applicable

Affiliates or any of the Subject Companies, (D) the amount of any proposed
adjustments (and the principal reason therefor) relating to any Returns for Tax
liability of Seller, its Affiliates or any of the Subject Companies which have
been proposed or assessed by any taxing authority and not yet finally resolved
and (E) a list of all written notices received by Seller, its Affiliates or any
of the Subject Companies from any taxing authority pertaining to the
commencement of an audit, asserting a tax liability or directed specifically to
any of the Subject Companies, Seller or its Affiliates and raising an issue

Subject





                                      -46-

Companies, which issue has not been finally determined and which, if determined
adversely to Seller, its Affiliates or any such Subject Companies, could result
in a Tax liability.

                  (ii)    Except as provided on Schedule 4.14(c)(ii) attached
hereto and in Section 4.14(c)(vi), neither Seller, any Affiliate of Seller, nor
any of the Subject Companies has been included in any "consolidated," "unitary"
or "combined" Return provided for under the law of the United States, any
foreign jurisdiction or any state or locality with respect to Taxes for any
taxable period for which the statute of limitations has not expired.

                 (iii)    Except as set forth on Schedule 4.14(c)(iii) attached
hereto, all Taxes which Seller, any Affiliate of Seller or any of the Subject
Companies is (or was) required by law to withhold or collect have been duly
withheld or collected, and have been timely paid over to the proper authorities
to the extent due and payable.

                  (iv)    Except as disclosed on Schedule 4.14(c)(iv) attached
hereto and except for any agreements set forth in the Schedules under Section
4.11 of this Agreement, there are no tax sharing, tax allocation, tax
indemnification or similar agreements or arrangements in effect as between
Seller, any Affiliate of Seller, any Subject Company, or any predecessor or
affiliate thereof and any other party under which Purchasers, any of the
Subject Companies or any of the Finland Assets or ADC Assets could be liable
for any Taxes or other claims of any party which could individually result in a
Tax liability in excess of $100,000.

                   (v)    Notwithstanding the foregoing, the representations
contained in this Section 4.14(c) shall apply to Seller and its Affiliates
(other than the Subject Companies) only to the extent such matters relate to
the Finland Assets and the ADC Assets.

                  (vi)    API, PC, APCS, POSCO and other API Subsidiaries ("API
and its Subsidiaries") are members of AIH's affiliated group (as such term is
defined in Section 1504 of Code).  API and its Subsidiaries will be included in
AIH's consolidated federal income tax returns for the taxable period of January
1, 1995 through the Closing Date.

                 4.15.  Liabilities.  (a) Neither Seller (in respect of the
Power Generation Business) nor any Subject Company had as of April 30, 1995, or
will have as at the Closing, any outstanding liability or indebtedness for
borrowed money or





                                      -47-
<PAGE>   58




other liability or indebtedness in excess of $250,000, contingent or otherwise,
except as set forth on Schedules 4.11(a) through (p), Schedule 4.13 or Schedule
4.19 and except as reflected in or reserved against on the Interim Balance
Sheet, other than liabilities incurred subsequent to April 30, 1995 in the
ordinary course of business consistent with past practice.

                 (b)  Except as set forth on Schedules 4.11(f), 4.11(k),
4.11(m), 4.13, 4.14, 4.15 and 10.4(a) attached hereto, neither Seller (in
respect of the Power Generation Business) nor any Subject Company had as of
December 31, 1994 any contingent liability that would have been required to be
disclosed in footnotes to the Financial Statements in accordance with
International Accounting Standards Consistently Applied if such footnotes were
prepared.

                 4.16.  Insurance.  (a)  Set forth in Schedule 4.16 attached
hereto is a complete list of insurance policies (together with policy limits
and deductibles with respect thereto) which Subject Companies within the United
States maintain with respect to their respective businesses, properties or
employees other than any insurance policy maintained in connection with any
Employee Benefit Plan.  Seller has heretofore made available for inspection by
FW true and complete copies of all such insurance policies.  Such policies are
in full force and effect and are free from any right of termination (other than
for non-payment) on the part of the insurance carriers.  Schedule 4.16(a)
attached hereto describes insurance policies that have been issued by insurance
companies which are currently affiliated, directly or indirectly, with Seller.

                 (b)  Set forth in Schedule 4.16(b) attached hereto is a list
of surety bonds issued on behalf of each Subject Company and, in respect of the
Power Generation Business, on behalf of Seller.

                 4.17.  Intellectual Properties.  (a)  Schedule 4.17 attached
hereto sets forth: (i) a true and, to the best of Seller's and each Subject
Company's knowledge as of the date hereof, complete list of all patents, patent
applications, invention disclosures, registered copyrights, registered Marks,
any applications to register any copyrights and Marks and any material
unregistered copyrights and Marks and an identification of any material
computer software programs included in the Acquired Intellectual Property, (ii)
the name of the Person which owns such Acquired Intellectual Property and (iii)
in the case of Acquired Intellectual Property not





                                      -48-
<PAGE>   59




owned by Seller or a Subject Company, the agreement pursuant to which Seller or
a Subject Company has rights in the Acquired Intellectual Property or has
immunity from suit as to a third party's Intellectual Property.

                 (b)  The operation of the Power Generation Business in the
ordinary course in substantially the same manner as it had been operated by
Seller and its Affiliates prior to the date hereof requires or uses no rights
under Intellectual Property other than rights under the Acquired Intellectual
Property, Shared Assets which constitute Intellectual Property, and the rights
granted to Seller or the Subject Companies pursuant to agreements listed on
Schedule 4.17.

                 (c)  The Acquired Intellectual Property includes Intellectual
Property as to which Seller or a Subject Company is a licensee or otherwise has
rights to use by contract.  Except as otherwise set forth in Schedule 4.17,
Seller or such Subject Company has the right to transfer its rights in and to
such components of the Acquired Intellectual Property to Purchasers.  In no
event however will Seller be deemed to transfer to Purchasers greater rights in
Acquired Intellectual Property listed in Schedule 4.17 pursuant to Section
4.17(a)(iii) obtained from third parties than it has obtained pursuant to the
agreements or immunities from suit listed in Schedule 4.17 pursuant to Section
4.17(a)(iii).   Any representations made in Section 4.17 concerning Acquired
Intellectual Property which is listed or required to be listed in Schedule 4.17
pursuant to Section 4.17(a)(iii) are made to the best of Seller's and each
Subject Company's knowledge.

                 (d)  Except as otherwise set forth in Schedule 4.17, Seller or
such Subject Company has good title to the Acquired Intellectual Property, in
each case subject to no Encumbrances except for Permitted Encumbrances, and has
the right to sell, transfer, assign and license all right, title and interest
in and to the Acquired Intellectual Property.

                 (e)  To the best of Seller's and each Subject Company's
knowledge, each item of Acquired Intellectual Property, except as indicated in
Schedule 4.17, has been duly registered with, filed in, or issued by the
appropriate domestic or foreign governmental agency in the jurisdictions noted
on Schedule 4.17 and each such registration, filing and issuance remains in
full force and effect except as noted on Schedule 4.17.





                                      -49-
<PAGE>   60




                 (f)  Except as set forth in Schedule 4.17, neither Seller nor
any Subject Company is a party to, subject to or bound by any agreement,
judgment or decree which would prevent the execution, delivery or performance
by any of Seller or a Subject Company of any assignment or other transfer of
rights to Acquired Intellectual Property, and, except as set forth on Schedule
4.17, to the best knowledge of Seller and each Subject Company, no prior or
subsequent consent, approval, permit or authorization is required from any
third party or governmental or regulatory body to enable Seller or any Subject
Company to assign or otherwise transfer any Acquired Intellectual Property.

                 (g)  Except as otherwise set forth in Schedule 4.17, no claim
adverse to the interests of Seller or any Subject Company in the Acquired
Intellectual Property or agreements listed in Schedule 4.17 is pending, nor to
the best knowledge of Seller and each Subject Company, has been threatened or
asserted, in litigation or otherwise, no basis exists for any such claim and no
Person has infringed or otherwise violated Seller's or a Subject Company's
right in any of the Acquired Intellectual Property or agreements listed in
Schedule 4.17.  No litigation is pending wherein Seller (in respect of the
Power Generation Business) or any Subject Company is accused of infringing or
otherwise violating the Intellectual Property right of another, or of
breaching, in any respect, a contract conveying rights under Intellectual
Property.  No such claim has been asserted or threatened in writing against
Seller, in respect of the Power Generation Business, or any Subject Company,
nor, to the best knowledge of Seller and each Subject Company, are there any
facts that would give rise to or support such a claim.  No claim has been
asserted by or against Seller or any Subject Company in connection with the
misappropriation of confidential information or trade secrets relating to the
Power Generation Business nor, to the best knowledge of Seller and each Subject
Company, are there any facts that would give rise to or support such a claim.

                 4.18.  Compliance with Laws.  Except with respect to the
Environmental Laws and Regulations which are separately covered in Section
4.21, Seller and each Subject Company are in compliance with all applicable
laws, regulations, orders, judgments and decrees (including, without
limitation, the Export Administration Act of 1979, 50 U.S.C. App. Section 2401,
et seq. and the related regulations set forth at 15 CFR Section 768, et seq.)
in connection with the conduct of the Power Generation Business or the
ownership of the Assets, except where the failure to so comply would not





                                      -50-

have a Material Adverse Effect or a Material Adverse Effect on any of Ahlstrom
Boilers, AF or API.

                 4.19.  Employment Relations.  (a)  Neither Seller (in respect
of the Power Generation Business) nor any Subject Company is engaged in any
unfair labor practice; (b) no unfair labor practice complaint against Seller
(in respect of the Power Generation Business) or any Subject Company is pending
before the National Labor Relations Board or any other applicable regulatory
authority or agency; (c) there is no organized labor strike, dispute, slowdown
or stoppage actually pending or to the best knowledge of Seller and each
Subject Company threatened against or involving Seller (in respect of the Power
Generation Business) or any Subject Company; (d) to the best knowledge of
Seller and each Subject Company, no representation question exists respecting
the employees of Seller who are employed in the Power Generation Business, or
any Subject Company; (e) neither Seller (in respect of the Power Generation
Business) nor any Subject Company has been notified of any grievance which
could reasonably be expected to have a Material Adverse Effect and no
arbitration proceeding arising out of or under any collective bargaining
agreement is pending; (f) except as set forth in Schedule 4.19 attached hereto,
no collective bargaining agreement is binding upon or currently being
negotiated by Seller (in respect of the Power Generation Business) or any
Subject Company; (g) neither Seller (in respect of the Power Generation
Business) nor any Subject Company has experienced any organized labor strike or
material dispute, walkout, slowdown or stoppage during the three (3) years
prior to the date hereof; and (h) neither Seller (in respect of the Power
Generation Business) nor any Subject Company is in violation in any material
respect of any collective bargaining agreement to which it is a party.  Except
as disclosed in Schedule 4.11(a) through (p), Schedule 4.19 or Schedule 4.20 or
in the bylaws or the articles of incorporation of the Subject Companies, there
exists no written or oral employment, consulting, severance, or indemnification
agreements between Seller (in respect of the Power Generation Business) or any
Subject Company and any officer or employee of Seller or of any Subject Company
or any agreement that would give any Person the right to receive any payment
from Purchasers or any Subject Company as a result of the transactions
contemplated by this Agreement.

                 4.20.  Employee Benefit Plans.  (a)  List of Plans.  Set forth
in Schedule 4.20 attached hereto is an accurate and complete list of all
domestic and foreign (i) "employee benefit plans," within the meaning of
Section 3(3) of the





                                      -51-
<PAGE>   62




Employee Retirement Income Security Act of 1974, as amended, and the rules and
regulations thereunder ("ERISA") whether or not subject to ERISA; (ii) bonus,
stock option, stock purchase, restricted stock, incentive, profit-sharing,
pension or retirement, deferred compensation, medical, life, disability,
accident, accrued leave, vacation, sick pay, sick leave, supplemental
retirement and unemployment benefit plans, programs, arrangements, commitments,
policies or practices (whether or not insured); and (iii) employment,
consulting, termination, and severance contracts or agreements; for active,
retired or former employees or directors, whether or not any such plans,
programs, arrangements, commitments, contracts, agreements or practices
(referred to in (i), (ii) or (iii)) are in writing or are otherwise exempt from
the provisions of ERISA; that have been established, maintained or contributed
to (or with respect to which an obligation to contribute has been undertaken)
by the Subject Companies, other than any such plan, program, arrangement,
agreement, practice, policy or commitment required by law ("Employee Benefit
Plans").

                 (b)  Status of Plans.  Each Employee Benefit Plan (other than
any "multiemployer plan" within the meaning of Section 4001(a)(3) of ERISA (a
"Multiemployer Plan")) has at all times been maintained and operated in
substantial compliance with its terms and the requirements of all applicable
laws, including, without limitation, ERISA and the Code.

                 (c)  Liabilities.  No employee benefit plan subject to Section
412 of the Code or Section 302 of ERISA which the Subject Companies or any
other trade or business (whether or not incorporated) which would be treated as
a single employer with any Subject Company for purposes of such Sections or
Title IV of ERISA (the "Seller Controlled Group") maintains or contributes to
(other than any Multiemployer Plan) has incurred any accumulated funding
deficiency within the meaning of Section 412 of the Code or Section 302 of
ERISA, respectively, or has applied for or obtained a waiver from the Internal
Revenue Service ("IRS") of any minimum funding requirement under Section 412 of
the Code.  Except for payments of premiums to the Pension Benefit Guaranty
Corporation ("PBGC"), no member of the Seller Controlled Group (i) has incurred
any unsatisfied liability (including, for this purpose and for the purpose of
all of the representations in this Section 4.20, any indirect, contingent, or
secondary liability) to the PBGC, including, without limitation, any liability
under Section 4069 or 4212(c) of ERISA or any penalty imposed under Section
4071 of ERISA, or (ii) has ceased operations at any facility or withdrawn from
any plan in a





                                      -52-
<PAGE>   63




manner which could subject it to liability under Section 4062, 4063 or 4064 of
ERISA, or (iii) knows of any facts or circumstances that could reasonably be
expected to give rise to any liability of Seller or any of the Subject
Companies to the PBGC under Title IV of ERISA, in any such case, that could
reasonably be anticipated to result in any claims being made against Purchasers
by the PBGC.  No complete or partial termination of any employee benefit plan
subject to Title IV of ERISA has occurred other than a standard termination
pursuant to Section 4041(b) of ERISA for which any member of the Seller
Controlled Group has any liability and no facts or circumstances currently
exist that could reasonably be expected to result in any such complete or
partial termination with respect to any plan maintained or contributed to by
any member of the Seller Controlled Group.

                 No member of the Seller Controlled Group has incurred any
unsatisfied withdrawal liability (including any contingent or secondary
withdrawal liability) within the meaning of Section 4201 or 4204 of ERISA to
any Multiemployer Plan.  To the best of Seller's and the Subject Companies'
knowledge, there are no facts or circumstances currently existing that could
reasonably be expected to give rise to any material liability of any Subject
Company to any Multiemployer Plan as a result of the termination,
reorganization, partition or insolvency of any such plan.

                 No Subject Company maintains any Employee Benefit Plan which
is a "group health plan" (as such term is defined in Section 5000(b)(1) of the
Code) that has not been administered and operated in all material respects in
compliance with the applicable requirements of Section 601 of ERISA and Section
4980B(f) of the Code and that is subject to such Sections and no Subject
Company is subject to any material liability, including, without limitation,
additional contributions, fines, penalties or loss of tax deduction (other than
any liability to provide the benefits under such plan in the ordinary course of
business) as a result of such administration and operation.  Except as
disclosed on Schedule 4.20, no Subject Company maintains any Employee Benefit
Plan in the U.S. (whether qualified or nonqualified within the meaning of
Section 401(a) of the Code) providing for retiree health and/or life benefits
and having unfunded liabilities.  No Subject Company maintains any Employee
Benefit Plan which is an "employee welfare benefit plan" (as such term is
defined in Section 3(1) of ERISA) that has provided any "disqualified benefit"
(as such term is defined in Section 4976(b) of the Code) with respect to which
an excise tax could be imposed under such section.





                                      -53-
<PAGE>   64





                 Except as indicated on Schedule 4.20, all Employee Benefit
Plans are unfunded.

                 No member of the Seller Controlled Group has incurred any
unsatisfied liability for any tax or excise tax arising under Section 4971,
4977, 4978, 4978B, 4979, or 4980 of the Code, and no event has occurred and no
condition or circumstance exists that could reasonably be expected to give rise
to any such liability of any of the Subject Companies.

                 No asset of any member of the Seller Controlled Group is
subject to any lien arising under Section 302(f) of ERISA or Section 412(n) of
the Code, and no event has occurred and no condition or circumstance exists
that could reasonably be expected to give rise to any such lien.  No member of
the Seller Controlled Group has been required to provide any security under
Section 307 of ERISA or Section 401(a)(29) or 412(f) of the Code, and no event
has occurred and no condition or circumstance exists that could reasonably be
expected to give rise to any such requirement to provide any such security.

                 There are no actions, suits or claims pending, or, to the best
knowledge and belief of Seller and the Subject Companies, threatened,
anticipated or expected to be asserted against any Employee Benefit Plan or the
assets of any such plan (other than routine claims for benefits and appeals of
denied routine claims).  No civil or criminal action brought pursuant to the
provisions of Title I, Subtitle B, Part 5 of ERISA is pending or, to the best
knowledge and belief of Seller and the Subject Companies, threatened,
anticipated, or expected to be asserted against any of the Subject Companies
or, to the best knowledge and belief of Seller and the Subject Companies,
against any other person whom any Subject Company has an obligation to
indemnify with respect to such matters in any case with respect to any Employee
Benefit Plan.  No Employee Benefit Plan or any fiduciary thereof has been the
direct or indirect subject of an audit, investigation or examination by any
governmental or quasi-governmental agency resulting in a material liability
within the preceding five years.

                 (d)  Contributions.  Full payment has been made of all amounts
which Seller or any of the Subject Companies is required, under applicable law
or under any employee benefit plan or any agreement relating to any employee
benefit plan with respect to which any of the Subject Companies may incur
(directly or indirectly) any liability, to have paid as contributions thereto
and/or as premiums thereunder as of the





                                      -54-
<PAGE>   65




last day of the most recent fiscal year of such Employee Benefit Plan ended
prior to the date hereof.

                 (e)  Withdrawal Liability.  As of the date of this Agreement,
using actuarial assumptions and computation methods consistent with Subpart 1
of Subtitle E of Title IV of ERISA, the aggregate liabilities of the Subject
Companies to all Multiemployer Plans in the event of a complete withdrawal
therefrom, as of the close of the most recent fiscal year of each Multiemployer
Plan ended prior to the date hereof, would not exceed one hundred twenty-five
thousand US dollars ($125,000).  To the best knowledge of Seller and the
Subject Companies, there has been no material change in the financial condition
of any Multiemployer Plan, in any such actuarial assumption or computation
method or in the benefits under any Multiemployer Plan as a result of
collective bargaining or otherwise since the close of each such fiscal year
which, individually or in the aggregate, would materially increase such
liability.

                 (f)  Tax Qualification.  The Ahlstrom Group Retirement Savings
Plan for U.S. Employees has been determined to be qualified under Section
401(a) of the Code by the IRS and an application with the IRS has been
submitted with respect to the qualification of such plan under the applicable
provisions of the Code as in effect through the Omnibus Budget Reconciliation
Act of 1993.  The trust established in connection with such plan is exempt
under Section 501(a) of the Code.  Since the date of the most recent such
determination with respect to such plan, no event has occurred and no condition
or circumstance has existed that resulted or is likely to result in the
revocation of such determination or that could reasonably be expected to
adversely affect the qualified status of such plan or the exempt status of such
trust.

                 (g)  Transactions.  Except with respect to a reportable event
described in Section 4043(c)(9) of ERISA resulting from the transactions
contemplated by this Agreement, no "reportable event" (as such term is defined
in Section 4043 of ERISA) for which the 30-day notice requirement has not been
waived by the PBGC has occurred or is expected to occur with respect to any
employee benefit plan with respect to which any member of the Seller Controlled
Group may have any liability.  None of Seller nor any of the Subject Companies
nor any of their respective directors, officers, employees or, to the best
knowledge of Seller and the Subject Companies, other persons who participate in
the operation of any employee benefit plan or related trust or funding vehicle,
has engaged in any transaction with respect to any





                                      -55-
<PAGE>   66




employee benefit plan or breached any applicable fiduciary responsibilities or
obligations under Title I of ERISA that would subject the Subject Companies to
a material tax, penalty or liability for prohibited transactions under Sections
409, 502(i) or 502(l) of ERISA or Section 4975 of the Code or could reasonably
be expected to result in any material claim being made under, by or on behalf
of any such employee benefit plan against the Subject Companies by any party
with standing to make such claim.

                 (h)  Triggering Events.  Except as expressly contemplated by
Sections 9.1, 9.2 and 9.3, the execution of this Agreement and the consummation
of the transactions contemplated hereby, do not constitute a triggering event
under any Employee Benefit Plan, which (either alone or upon the occurrence of
any additional or subsequent event) will result in any obligation on the
Subject Companies to make any payment (whether of severance pay (including, and
not limited to, salary, related vacation pay, pension pay and other similar
payments and costs) or otherwise) or to accelerate, vest or increase the amount
of benefits payable to any employee or former employee or director of any of
the Subject Companies.  Except as listed on Schedule 4.20(h) attached hereto,
no Employee Benefit Plan provides for the payment of severance benefits upon
the termination of an employee's employment.

                 (i)  Documents.  As of the date hereof, Seller has made
available to FW and its counsel true and complete (as of the date hereof)
copies of all material documents in connection with each Employee Benefit Plan
other than any Multiemployer Plan, including, without limitation (where
applicable):  (i) all Employee Benefit Plans as in effect on the date hereof,
together with all amendments thereto, including, in the case of any Employee
Benefit Plan not set forth in writing, a written description thereof; (ii) all
current summary plan descriptions, summaries of material modifications, and
material communications; (iii) all current trust agreements, declarations of
trust and other documents establishing other funding arrangements (and all
amendments thereto and the latest financial statements thereof); (iv) the most
recent IRS determination letter obtained with respect to each such Employee
Benefit Plan intended to be qualified under Section 401(a) of the Code or
exempt under Section 501(a) of the Code; (v) Form 5500 for each of the last two

management reports of the Power Generation Business conducted by Seller and its
Affiliates for the period ended as of the prior month, which restatements shall

Material Adverse Effect.

                 8.3.  Exclusive Dealing.  During the period from the date of

Agreement, Seller shall not, and shall not permit any of its Affiliates or
their respective officers, directors, employees and advisors to, take any
action to, directly or indirectly, encourage, initiate or engage in discussions
or negotiations with, or provide any information to, any Person other than
Purchasers, concerning any sale of the Power Generation Business, the Assets or
any material part thereof or any similar transaction.  Seller will promptly
communicate to FW terms of any proposal or inquiry that it may receive in
respect of any such transaction or of any such negotiations or discussions
being sought to be

<PAGE>   86





initiated with Seller and the nature of any such information requested from it,

Power Generation Business, including, without limitation, (i) the Assets, (ii)
the complete working papers of Seller's and each Subject Company's independent
public accountants underlying their report on the Financial Statements, (iii)

fiscal year ended on the Balance Sheet Date) of employees of Seller whose
duties are primarily devoted to the Power Generation Business and employees of
each Subject Company and ADC who may be employed by FW or an Affiliate of FW
subsequent to the Closing Date and (iv) the Books and Records of Seller, the
Subject Companies and ADC as FW deems necessary or advisable to familiarize
itself with the Power Generation Business and the ADC Assets and related
matters; such review shall not, however, affect the representations and
warranties made by Seller hereunder or the remedies of Purchasers for breaches
of those representations and warranties.  Such review shall occur only during
normal business hours and upon reasonable notice by FW.  Except to the extent
relating to the categories of items listed on Schedule 8.4 attached hereto to
which FW may have access directly or indirectly through its representatives
after the later of the Antitrust Clearance Date and the Environmental Audit
Acceptance Date, Seller shall permit FW and its representatives to have, after
the execution of this Agreement, supervised access on reasonable prior notice
during normal business hours, to the extent possible without undue disruption
of operations of the Power Generation Business, to the employees of Seller and
the Subject Companies listed on Schedule 8.4 attached hereto who can furnish
Purchasers with financial and operating data and other information with respect
to the Power Generation Business as any Purchaser shall from time to time
reasonably request.  In connection with such review, FW shall be permitted to
make copies, at its own expense, of any of the documents reviewed by it.

Notification and Report Forms under the HSR Act with the Federal Trade
Commission and the Antitrust Division of the Department of Justice (the "HSR
Filing") and may make other filings as required or deemed appropriate with
other antitrust, competition and other governmental authorities.  Seller and FW
each agrees that it will cooperate with the other in all respects in connection
with such filings and in connection with any requests for information or
further filings which may be necessary in order to obtain the necessary
consents (or to allow the applicable time periods to expire) with respect
thereto.

                 8.6.  Environmental Audit.  Promptly after the execution of
this Agreement, FW and Seller shall instruct Geraghty & Miller, Inc. (the

                 8.7.  Building and Site Inspection.  Seller shall permit
Purchasers or their representatives or agents to enter the real property
(whether leased or owned by a Seller or a Subject Company) described in
Schedules 4.9 and 4.10 and the structures thereon (herein sometimes called the
"Premises") at any reasonable time or times during normal business hours with
prior notification to inspect the Premises and the installations thereon, and
to make such surveys as Purchasers reasonably require, and to examine and copy,
at Purchasers' sole cost, all existing plans, building permits, title, deeds,
reports, surveys, working drawings and specifications of the Premises as are in
any Seller's possession (all of the foregoing herein referred to as the
"Building Inspection"), provided that such Building Inspection does not unduly
interfere with  Seller's or a Subject Company's normal business operations
conducted on the Premises and shall not cause in any event any shutdown of
Seller's or a Subject Company's operations.

                 8.8.  Non-Competition; Confidentiality.  (a)  Seller agrees
that from the Closing Date until the fifth (5th) anniversary of the Closing
Date (the "Restricted Period"), it will not, and will cause its Affiliates not
to, directly or indirectly own, manage, operate, control, or participate in the
ownership, management, operation or control of, or be connected in any manner
with any Person that competes with the Power Generation Business.  Ownership of
less than 5% of the voting power of the securities of such a company whose
securities are publicly traded shall not be a violation of this Section 8.8(a).
Nothing in this Section





                                      -77-
<PAGE>   88





8.8 shall be construed to prevent Seller from (i) engaging in the Recovery
Boiler Business or (ii) engaging in the business of all aspects of manufacture
of plants and equipment (other than power boilers except as provided below) and
processing of pulp, paper and other forest products including, without
limitation, handling, processing and/or disposal of waste streams from pulp or
paper mills, chemical recovery boiler processes and equipment, and the design
and furnishing of equipment therefor, and the delivery of recovery boiler
islands and of power boilers manufactured by a Person other than Seller or any
Affiliate of Seller in connection therewith.  In addition to the foregoing, it
shall not constitute a breach of this covenant if Seller or any Affiliate
acquires the stock or assets of any entity that derives less than 10% of its
revenues from a business competitive with the Power Generation Business
provided that Seller or such Affiliate divests the assets comprising or
relating primarily to the Power Generation Business within six months after
such acquisition.

                 (b)  Seller agrees, covenants and acknowledges that from and
after the Closing Date, it will not disclose, give, sell, use or otherwise
divulge any Confidential Information relating to the Power Generation Business
or the ADC Assets.

                 (c)  In the event Seller or its Affiliates, or their
respective employees, officers, directors or advisors become legally compelled
to disclose any Confidential Information, Seller shall provide Purchasers with
prompt written notice of such requirement so that Purchaser may seek a
protective order or other remedy or waive compliance with this Section 8.8.  In
the event that such protective order or other remedy is not obtained, or
Purchasers waive compliance with this Section 8.8, Seller shall furnish only
that portion of Confidential Information which is legally required to be
provided and exercise its best efforts to obtain assurances that appropriate
confidential treatment will be accorded Confidential Information.

                 (d)  The confidentiality and restrictive use obligations under
this Section 8.8 shall not apply to any information that, at the time of
disclosure, is or subsequently becomes available publicly; provided, however,
that such information was not disclosed in breach of this Agreement by the
disclosing party or any of its Affiliates or their respective employees,
officers, directors or advisors.

                 (e)  It is the desire and intent of the parties to this
Agreement that the provisions of this Section 8.8 shall





                                      -78-
<PAGE>   89





be enforced to the fullest extent permissible under the laws and public
policies applied in each jurisdiction in which enforcement is sought.  If any
particular provisions or portion of this Section 8.8 shall be adjudicated to be
invalid or unenforceable, this Section shall be deemed amended to delete
therefrom such provision or portion adjudicated to be invalid or unenforceable,
such amendment to apply only with respect to the operation of such Section in
the particular jurisdiction in which such adjudication is made.

                 (f)  Seller recognizes that the performance of the obligations
under this Section 8.8 are special, unique and extraordinary in character, and
that in the event of the breach by Seller, its Affiliates or their respective
employees, officers, directors or advisors of the terms and conditions of this
Section 8.8, Purchasers shall be entitled, if they so elect, to institute and
prosecute proceedings in any court of competent jurisdiction, either at law or
in equity, to enforce the specific performance thereof by Seller or to enjoin
Seller, its Affiliates or their respective employees, officers, directors or
advisors from violating the provisions of this Section 8.8.

                 8.9.  Notice of Sale.  As reasonably requested by Purchasers,
from time to time Seller will prepare and mail notices to third parties under
any of the Assigned Contracts and other agreements assigned to Purchasers by
Seller, advising such other party that such Assigned Contract or other
agreement has been assigned to a Purchaser and directing such other party to
send to such Purchaser all future notices and correspondence relating to such
agreements.

                 8.10.  Further Assurances.  At any time or from time to time
after the Closing Date, Seller shall, at the reasonable request of a Purchaser,
execute and deliver any further instruments or documents and take all such
further action as such Purchaser may reasonably request in order to consummate
and make effective the sale of the Assets and the assumption of the Assumed
Obligations and the sale of Stock pursuant to this Agreement.

                 8.11.  Reorganizational Transactions.  Prior to the Closing,
Seller and AIH shall cause (a) API to distribute all of the capital stock of
ADC to an Affiliate of Seller (other than a Subject Company), (b) ADC to

(c) ADC to transfer to API those of its employees requested to be so

"Reorganizational Transactions").  Seller or an Affiliate of Seller (other than
a Subject Company) shall bear any and all Taxes, costs and expenses related to
the Reorganizational Transactions.

                 8.12.  Insurance; Risk of Loss.  (a)  To the extent that (i)
there are insurance policies maintained by Seller or its Affiliates (other than
the Subject Companies) ("Ahlstrom Insurance Policies") insuring against any
loss, liability, damage or expense relating to the assets, operation, and
employees (including former employees) of the Power Generation Business
("Subject Company Liabilities") and relating to or arising out of acts or
omissions occurring on or prior to the Closing, and (ii) Ahlstrom Insurance
Policies continue after Closing to permit claims to be made with respect to
such Subject Company Liabilities relating to or arising out of acts or
omissions occurring on or prior to the Closing (such claims, the "Subject
Company Claims"), to the extent assignable, Seller shall assign such Subject
Company Claims to Purchasers and to the extent not assignable, Seller shall and
shall cause such Affiliates to submit and otherwise to administer the
collection of payment in respect of Subject Company Claims on behalf of
Purchasers and the Subject Companies under Ahlstrom Insurance Policies.
Purchasers shall be responsible for insurance coverage with respect to Subject
Company Liabilities to the extent relating to or arising out of acts or
omissions occurring after the Closing.

                 (b)  Seller shall immediately reimburse the Subject Companies
for any deductible payment made in connection with a Subject Company Claim that
would have resulted in a Subject Company Claim and a payment in respect thereof
under an Ahlstrom Insurance Policy but for the fact that the Subject Company
Claim did not exceed the relevant deductible amount.  Seller shall immediately
reimburse the Subject Companies for all self-insured retention amounts,
retrospective premiums and all other costs and charges incurred by the Subject
Companies in respect of a Subject Company Claim to the extent amounts in
respect of such Subject Company Claim exceed the amount reserved therefor on
the Final Closing Balance Sheet.

                 (c)  On the Closing Date, Seller shall, and shall cause its
Affiliates to include FW and each Purchaser and the Subject Companies as named
insureds on the insurance policies then maintained by Seller or their
Affiliates with respect to Subject Company Claims and for five (5) years
thereafter shall, and shall cause its Affiliates to, continue to maintain
reasonably equivalent (that is, at least equivalent types, limits, forms, and
quality insurers) insurance.

                 8.13.  Receivables Repurchase.  (a)  On the last Business Day
of each month following the Closing Date, FW may deliver a certificate to
Seller certifying an amount equal to the excess of (1) the billed Accounts
Receivable set forth on the Final Closing Balance Sheet which remain
uncollected and 180 days or more overdue over (2) the amount of applicable
reserves or contingencies included in the Final Closing Balance Sheet or the
relevant Project Budget for such Accounts Receivable (the "Uncollected
Receivables").  In determining whether any billed Accounts Receivable set forth
in the Final Closing Balance Sheet remain uncollected and 180 days or more
overdue, all payments from an account receivable debtor shall be applied to
payment of the oldest outstanding account receivable of that debtor, unless
otherwise specifically stated with such payment or unless such debtor disputes
that any such account receivable is owing, in which event payment shall be
applied to the next oldest account of such debtor not in dispute.  Within five
(5) Business Days of receipt of each such certificate, Seller shall pay FW in
immediately available funds the face amount of the Uncollected Receivables
specified in such certificate.  The certificate delivered by FW pursuant to
this Section 8.13(a) shall state that it has complied, in all material
respects, with clause (a) and has complied with clause (b) of Section 10.9.

                 (b)  Any disputes with respect to the obligation of the Seller
to purchase the Uncollected Receivables shall be resolved in accordance with
Section 14.11.  Any amounts that are required to be repaid to Seller by FW
shall be repaid with interest calculated at the US Prime Rate.

                 (c)  The receipt of payments from Seller referred to in
Section 8.13(a) shall, to the extent permitted by applicable law, be treated as
an adjustment to the Purchase Price.

                 8.14.  Registrations and Use of Names.  (a)  Prior to the
Closing Date, Seller shall, upon FW's reasonable request, apply for appropriate
registration of any Marks, used by Seller or any of its Affiliates (including
any Subject Company) in connection with the Power Generation Business,
including, without limitation, application for registration of the "PYROPOWER"
mark (by itself or together with any other word, symbol, mark or phrase) in all
relevant classes, to the extent legally permitted and not in conflict with any
existing agreements to which Seller is subject; provided, however, that any
such agreement is listed in Schedule 4.17.





                                      -81-
<PAGE>   92





                 (b)  Seller agrees that, after the Closing Date, Seller and
its Affiliates shall discontinue all use of the name(s) "Ahlstrom Pyropower
Sector", "Ahlstrom Pyroflow", "Fluxflow", "Termoflow", "Pyropower", "Ecoflow",
"Ecofire", "Ahlguard", "CeraFilter", "Witermo", and "Bioflow", alone or in any
combination of words for any and all products and services, and will as
promptly as practicable but in no event more than thirty (30) days following
the Closing Date, eliminate such name(s) from all signs, purchase orders,
invoices, sales orders, packaging stock, labels, letterheads, shipping
documents and other materials used by it (other than appropriate references in
any Seller annual report).

                 8.15.  Guaranteed Cash Amount.  On or prior to the Cash
Guaranty Date, Seller shall deposit cash or cash equivalents necessary to
ensure that the Guaranteed Cash Amount is in the Power Generation Business on
the Cash Guaranty Date.

                 8.16.  Permits.  Within thirty (30) days after the date of
this Agreement, Seller shall deliver to FW a true and complete list of all
Permits required in connection with the use, operation or ownership of the
Assets, the assets of the Subject Companies and the conduct of the Power
Generation Business as conducted on the date hereof.

                 8.17.  Bank Accounts.  Not later than ten (10) days prior to
the Closing Date, Seller shall provide FW with (a) the name of each bank or
financial institution in which a Subject Company maintains an account (whether
checking, savings or otherwise), lock box or safe deposit box, the numbers (or
means of identification) of all such accounts, lock boxes or safe deposit boxes
and the names of all provisions authorized to draw thereon or to have access
thereto.

                 8.18.  Certain Employee Matters.  Neither Seller nor any of
its Affiliates shall for a period of two (2) years from the Closing Date
solicit the employment of, or induce any Person to engage in such solicitation,
of any employees hired by a Purchaser pursuant to this Agreement.

                 8.19.  Transfer of Bioflow Stock.  Prior to Closing the
parties shall agree on the value of the Bioflow Stock for purposes of the
allocation of the Purchase Price pursuant to Section 3.6 (the "Bioflow Price").

                 (a)  With respect to transfer of the Bioflow Stock in
accordance with Section 2.1(a), after the date hereof and prior to the Closing,
Seller shall notify Sydkraft Aktiebolag ("Sydkraft") and shall otherwise comply
with the provisions





                                      -82-
<PAGE>   93





set forth in Sections 15.3.2 and 15.3.3 of the Cooperation Contract dated June
28, 1991 between Seller and Sydkraft (the "Bioflow Agreement") and offer to
sell the Bioflow Stock to Sydkraft for the Bioflow Price.

                 (b)  If Sydkraft does not exercise its right of first refusal
and accept Seller's offer to sell the Bioflow Stock within the time period
provided in the Bioflow Agreement (the "Offer Period"), then the Bioflow Stock
shall be transferred to a Purchaser in accordance with the procedure specified
in Section 2.1(a) as soon as possible after expiration of the Offer Period
against receipt by Seller of the consideration specified in Section 3.1.

                 (c)  If Sydkraft elects to exercise its right of first refusal
and purchase the Bioflow Stock, then the Bioflow Price shall be retained by
Seller and Purchasers shall have no further rights or obligations with respect
to the Bioflow Stock.

                 8.20.  Contract Review.           (a)  Promptly after
execution of this Agreement Seller shall, and shall cause each Subject Company
to, make available to FW and its designated representatives of FW such
information as may be reasonably requested from time to time by FW to review
the Opening Backlog and Contribution I related to such Opening Backlog,
including, without limitation, (1) the information necessary for FW to complete
the contract review form attached hereto as Schedule 8.20(a)(1), (2) the
technical information referred to in Schedule 8.20(a)(2) attached hereto, (3)
true and correct copies of all contracts and (4) true and correct copies of the
most recent project budgets.  Seller also agrees to make available, or cause to
be made available, to FW and its designated representatives such employees of
Seller and Seller's Affiliates and other Persons as may be reasonably requested
by FW including, without limitation, project managers for each project and
other employees responsible for reviewing project budgets, determining
contingencies and reserves relating thereto and determining Contract Costs
attributable to Backlog.  FW agrees to complete its review of the Initial
Contacts and the Other Contracts, and propose any adjustments under Sections
8.20(b) and 8.20(c) as soon as practicable but in any event not later than
September 1, 1995.  Seller shall provide the information, and make available
the personnel, referred to above in a timely manner to afford FW the
opportunity to complete its review by such date.  Seller agrees to confirm in
writing or by acknowledging on FW's completed contract





                                      -83-
<PAGE>   94





review form certain factual information provided to FW, including amounts of
contingencies and reserves.

                 (b)      Promptly after the date hereof, Seller shall provide
to FW a true and correct list of all Booked Contracts and contracts under which
Seller or a Subject Company may be required to provide warranty service, in
each case with a contract price in excess of five million US dollars
($5,000,000) (together with the POSCO Contracts, the "Initial Contracts").
FW's designated representative shall review the Initial Contracts on a contract
by contract basis.  If FW proposes any adjustments to the project budgets
relating to any of the Initial Contracts which are accepted by Seller in
writing ("Agreed Adjustments"), such project budget shall be revised and
reflected in Seller's Books and Records and Contribution I shall be
appropriately adjusted.  Any adjustments proposed to the project budgets
relating to any of the Initial Contracts which are not accepted by Seller (the
"Disputed Adjustments") or which are proposed pursuant to Section 8.20(c) or
Section 8.20(e) and are not accepted by Seller shall not affect the applicable
project budget or reduce Contribution I.  A tabulation of the Disputed
Adjustments will be kept by FW and Seller and if the aggregate US dollar amount
of all Disputed Adjustments which, if accepted by Seller, would have had the
effect of reducing Contribution I by an amount which equals or exceeds five
million US dollars ($5,000,000) (the "Termination Threshold"), then either FW
or Seller may  terminate this Agreement by written notice to the other.  If
neither FW nor Seller receives such written notice from the other party within
five (5) Business Days after the Disputed Adjustments equal or exceed the
Termination Threshold, then such other party shall have deemed to waive its
right to terminate this Agreement under this Section 8.20(b) unless additional
Disputed Adjustments arise thereafter.  Until such time as either party
exercises its right to terminate this Agreement under this Section 8.20(b), FW
may continue to review the Initial Contracts on a contract by contract basis
and if further Disputed Adjustments arise, either party may elect to terminate
this Agreement in accordance with the procedure set forth above and if such
right is not exercised within five (5) Business Days such right will be waived
unless subsequent Disputed Adjustments arise.

                 (c)      Upon completion of the review of the Initial
Contracts by FW and its designated representatives, if the Disputed Adjustments
are less than the Termination Threshold or, if equal to or greater than the
Termination Threshold, each party's right to terminate this Agreement was
waived as





                                      -84-
<PAGE>   95





provided in clause (b) above, FW and its designated representatives may review
such other contracts in Backlog and any other contracts with open warranty
obligations ("Other Contracts") and project budgets relating thereto as may be
requested by FW from time to time but in any event prior to September 1, 1995.
If after completion of the review of the Initial Contracts, the Disputed
Adjustments are less than the Termination Threshold and based on its review of
the Other Contracts FW proposes adjustments to Contribution I which, together
with the Disputed Adjustments, equal or exceed the Termination Threshold,
either party may terminate this Agreement by written notice to the other party
within five (5) Business Days thereafter.  If neither party receives such
written notice from the other party, then such other party shall have deemed to
have waived its right to terminate this Agreement under this Section 8.20(c).

                 (d)      FW and its designated representatives will have the
right to review all Booked Contracts entered into by Seller or any of its
Affiliates with respect to the Power Generation Business after the date of this
Agreement and participate in the preparation of project budgets and the
determination of Contribution I attributable thereto.  FW and Seller in good
faith shall attempt to resolve any differences in good faith regarding the
Contribution I attributable to each such Booked Contract.

                 (e) (i) In the event that FW believes that Contribution I
should be adjusted by reason of the effects of objective events or developments
subsequent to the date of the respective Project Budgets and such adjustments
were not made by Seller pursuant to clause (ii) of Section 3.7, FW shall have
the right to terminate this Agreement if such adjustments, together with the
Disputed Adjustments and the aggregate amount of adjustments proposed by FW
under clause (c) above which are not accepted by Seller, equal or exceed the
Termination Threshold.  FW shall exercise its right to terminate this Agreement
by written notice to Seller; provided, however that such right shall be deemed
to have been waived by FW if such notice is not given to Seller within five (5)
Business Days after such right exists.

                 (ii)     Notwithstanding clause (i) above, if pursuant to this
Section 8.20, FW has previously had the right to terminate this Agreement but
elected not to exercise such right or waived such right, FW may only terminate
this Agreement under the circumstances described in such clause if the new
adjustment to Contribution I which FW believes should





                                      -85-
<PAGE>   96





be made equals or exceeds fifty thousand US dollars ($50,000).

                 (iii) Any objection by Seller to FW's proposed adjustment
under Section 8.20(e)(i) above which gave rise to FW's termination of this
Agreement shall be resolved in accordance with the provisions of Section 14.11.
The arbitrator will be deemed to have ruled in favor of FW if it finds that
FW's proposed adjustments were not unreasonable in light of all the
circumstances relating to such project or projects and without giving any
effect to the impact on either FW or Seller as a result of the termination of
this Agreement.

                 8.21.  Supplements to Certain Schedules.  From time to time
prior to the Closing Date, Seller may supplement Schedules 4.9, 4.10, 4.11
(other than (h) and (l)), 4.16, 4.17(a), 4.22, 4.23, 4.24, 4.36 and 4.37 with
respect to any matter hereafter arising which, if existing or occurring at or
prior to the date of this Agreement, would have been required to be set forth
or described in any such Schedule; provided, however, that any such matter
arose in the ordinary course of the Power Generation Business of Seller
consistent with Seller's obligations under Section 8.2 hereof.


                                   ARTICLE IX

                            CERTAIN BENEFITS MATTERS

                 9.1.  Retirement Plan.  Effective as of the Closing Date,
Seller shall cause the benefits under the Ahlstrom Group Retirement Plan for
U.S. Employees (the "Ahlstrom Retirement Plan") and under the Ahlstrom Group
Supplemental Executive Retirement Plan for U.S. Employees (the "Ahlstrom SERP")
of all employees of the Subject Companies and of those individuals whose names
are set forth on Schedule 4.23(a) (other than those to be retained by Seller as
indicated on Schedule 4.23(a)) ("Affected Employees") to be fully vested and
frozen, such that no compensation earned by, or service of, or other
circumstance with respect to, any Affected Employee relating to a period
following the Closing Date shall be taken into account in determining the
amount of the Affected Employee's accrued benefit under the Ahlstrom Retirement
Plan or the Ahlstrom SERP.

                 9.2.  Service.  Purchasers shall cause each Affected Employee
to be granted credit for eligibility and vesting (but not benefit accrual)
purposes under each





                                      -86-
<PAGE>   97





employee benefit plan, program, arrangement, agreement or commitment in which
such Affected Employee is eligible to participate following the Closing Date
for all service to the extent taken into account under a corresponding plan,
program, arrangement, agreement or commitment maintained by Seller or any of
its Affiliates prior to the Closing Date and listed on Schedule 4.20 or
Schedule 9.2.  Purchasers shall cause each Affected Employee to be granted
credit for purposes of determining the amount of the benefit to which such
Affected Employee is entitled under any severance plan, program, or
arrangement, and for purposes of determining the amount of vacation to which
each Affected Employee is entitled, following the Closing Date for all service
to the extent taken into account under the corresponding Employee Benefit Plan
maintained by the employer of such Affected Employee prior to the Closing Date.

                 9.3.  Savings Plan.  Effective as of the Closing Date, Seller
shall cause the benefits under the Ahlstrom Group Retirement Savings Plan for
U.S. Employees (the "Ahlstrom Savings Plan") of Affected Employees to become
fully vested.  As soon as practical after the Closing Date, Purchaser shall, at
the request of applicable Affected Employees, make available a tax-qualified
defined contribution plan specified by Purchaser (the "FW Savings Plan") to
accept eligible rollovers (including direct rollovers) of such Affected
Employees' account balances in the Ahlstrom Savings Plan, subject to such terms
and conditions as FW may reasonably require.

                 9.4.  Termination of Employee Benefit Plans.  Seller covenants
and agrees that upon reasonable advance written notice by FW to Seller prior to
the Closing, Seller shall terminate or cause to be terminated, effective no
later than as of the Closing, any employee benefit plan, program, arrangement,
agreement or commitment maintained or sponsored by any Subject Company that is
specified by FW in such notice (each a "Terminated Plan" and collectively the
"Terminated Plans").

                 9.5.  Finnish Employee Benefits.  (a)  The Finnish personnel
employed by Seller for the Power Generation Business as indicated on Schedule
4.23 (a) hereto (the "Finnish Transferred Employees") shall be transferred from
Seller to Purchasers under Section 7 of the Finnish Act on Employment Contracts
(tyosopimuslaki).  Seller will separately provide Purchasers with additional
information about each of the Finnish Transferred Employees (including his or
her job title, annual compensation, age and length of





                                      -87-
<PAGE>   98





service) within 5 days after the later to occur of the Environmental Audit
Acceptance Date and the Antitrust Clearance Date.

                 (b)  Seller shall pay, or appropriately reflect on the Final
Closing Balance Sheet, the salaries, wages, fringe benefits and pensions of the
Finnish Transferred Employees, up to the Closing Date, whereafter Purchasers
shall be responsible for them; provided, however, that Seller will be
responsible on accrual basis for "holiday compensation" (lomakorvaus), "holiday
pay (lomapalkka), "end-of-holiday pay" (lomaltapaluuraha), "pension and social
security charges" (elake-ja sosiaaliturvamaksut), "accrued shortening of
working time" (kertynyt tyoajan lyhennys), "free shift compensation"
(vapaavuorokorvaus) and other similar "charges" (maksut), to the extent such
"charges" are related to the time before the Closing Date.

                 (c)  The parties furthermore expressly agree that Purchasers
shall be responsible for "disability pension premium"
(tyokyvyttomyyselakevakuutusmaksu), "individual early retirement pension
premium" (yksilollinen varhaiselakevakuutusmaksu), "unemployment pension
premium" (tyottomyyselakevakuutusmaksu) if the "occurrence of pension"
(elaketapahtuma) takes place on or after the Closing Date, whereas, Seller
shall be responsible for them if the "occurrence of pension" takes place before
the Closing Date.

                 (d)  The calculations regarding the items set forth in Section
9.5(b) above will be based upon the wage and salary level of the personnel at
the Closing Date.  The "pension charge" (TEL-maksu), "social security charge"
(sosiaaliturvamaksu), "accident insurance charge" (tapaturmavakuutusmaksu),
"unemployment insurance charge" (tyottomyysvakuutusmaksu) and "group life
insurance" (ryhmahenkivakuutusmaksu) shall be computed using the same
percentages as used in the Balance Sheet.  If, however, the percentage used,
wage and salary paid by Purchasers when actually paying the amounts specified
in Section 9.5(b) above, is lower, this lower percentage, wage and salary shall
be used in the computation.

                 9.6.     Health Insurance Run-Off Claims.  Except as provided
in this Section 9.6, Seller shall be responsible for all claims incurred on or
prior to the Closing Date under the health (including medical, dental and
vision) insurance plans for the benefit of employees of API and its
subsidiaries that are Subject Companies and ADC, subject to the terms and
conditions of those plans.  FW shall cause API to be





                                      -88-
<PAGE>   99





responsible for all such claims for employees of API and its subsidiaries that
are Subject Companies and ADC (other than employees of ADC who will be retained
by Seller as indicated on Schedule 4.23(a)) incurred after the Closing Date,
subject to the terms and conditions of the plans, if any, maintained by
Purchaser or API.  For purposes of this Section 9.6, a claim shall be deemed to
be incurred when the cost or expense that is reimbursable under the applicable
plan arises.  Purchaser agrees to cause API to administer the claims process
with respect to claims for which Seller is responsible pursuant to this Section
9.6 in accordance with the terms of the applicable plans, applicable law and
prior practice, and to pay out all benefits due under the terms of the
applicable plan.  Seller agrees to reimburse FW or API for the amount of such
benefits no later than thirty days following receipt of a statement therefore
together with a detail of the nature and amount of the claims paid; provided,
however, that Seller shall not be required to reimburse FW or API for any
amount which FW or API is entitled to recover under any "stop-loss" or similar
insurance policy maintained by API as of the Closing.  In the event that any
person contests any determination by FW or API to deny a claim made under any
such plan, FW or API shall notify Seller as soon as practicable (but in any
event prior to the passage of time that would materially prejudice the Seller's
ability to deny such contest) after it is notified of such contest, in which
case Seller shall assume full responsibility and authority for the
administration of such claim and the resolution of such contest and shall
indemnify and hold the Purchaser Indemnified Parties harmless from any claim,
liability, cost or expense (including reasonable attorneys' fees) arising
therefrom.

                                   ARTICLE X

                            COVENANTS OF PURCHASERS

                 Each of Purchasers hereby covenants and agrees with Seller as
follows:

                 10.1.  Cooperation by Purchasers.  Subject to Sections 2.5 and
2.6, each of Purchasers will use their best efforts, and will cooperate with
Seller, to secure all necessary consents, approvals, authorizations, exemptions
and waivers from third parties as shall be required in order to enable such
Purchaser to effect the transactions contemplated on its part hereby, and each
Purchaser will otherwise use its best efforts to cause the consummation of such
transactions in accordance with the terms and conditions hereof and to





                                      -89-
<PAGE>   100





cause all conditions contained in this Agreement over which it has control to
be satisfied.  Nothing in this Section 10.1 or any other provision of this
Agreement shall require any Purchaser to agree to divest all or any portion of
the Power Generation Business or to take any other action that may in the
reasonable judgment of FW materially adversely affect the conduct of the Power
Generation Business or a related business conducted by FW or any of its
Affiliates in order to obtain any consent or approval (including, without
limitation, under the HSR Act) necessary to consummate the transactions
contemplated by this Agreement.

                 10.2.  Books and Records; Personnel.  At all times after the
Closing Date, each Purchaser shall allow Seller and any agents of Seller, upon
reasonable advance notice to such Purchaser, access to all Books and Records
and personnel of Seller and the Subject Companies which are transferred to
Purchaser in connection herewith, to the extent necessary in connection with
pre-Closing transactions, or preparation for, existing or future litigation,
employment matters, tax returns (including those necessary to establish tax
credits) or audits, or reports to or filings with governmental agencies, during
normal working hours at Purchaser's principal places of business or at any
location where such Books and Records are stored, and Seller shall have the
right, at its cost, to make copies of any such Books and Records.

                 10.3.  Further Assurances.  At any time or from time to time
after the Closing Date, Purchasers shall, at the request of any Seller, execute
and deliver any further instruments or documents and take all such further

the sale of the Stock pursuant to this Agreement.

                 10.4.  Release of Seller from Certain Obligations; Surety
Bonds.  (a)  Purchasers agree to use commercially reasonable efforts to obtain
the release of Seller from each guaranty provided by Seller in connection with
the Power Generation Business purchased by Purchasers pursuant to this

equivalent Purchaser guarantees in order to obtain such releases.

                 (b)  Purchasers shall not be obligated to obtain the release
of, and Seller shall maintain, all surety bonds listed in Schedule 4.16(b)

of any Subject Company, or, in respect of the Power Generation Business,
Seller, through the completion of work covered by such surety bonds.

                 (c)  If FW is unable to obtain the release of any Seller
Guarantees, FW shall indemnify and hold harmless Seller from and against
liabilities under Seller Guarantees to the extent arising out of the conduct of
the Power Generation Business by FW after the Closing Date.  FW shall indemnify
and hold harmless Seller from and against liabilities arising under the surety
bonds referred to in paragraph (b) of this Section 10.4 to the extent arising
out of the conduct of the Power Generation Business by FW after the Closing.

                 10.5.  Confidentiality.  (a)  Purchasers agree that from the
date of this Agreement until the Closing (i) any Confidential Information
relating to Seller or its businesses including, without limitation, the Power
Generation Business and the Recovery Boiler Business, received by Purchasers or
Purchasers' advisors, whether received before or after the date hereof, shall
be kept confidential by Purchasers and Purchasers' advisors and shall be used
solely in furtherance of the transactions contemplated by this Agreement; (ii)
Purchasers shall not, and shall cause their advisors not to disclose or
distribute any Confidential Information in any manner whatsoever to any third
party without the prior written consent of Seller and; (iii) Purchasers agree,
covenant and acknowledge that from and after the Closing Date, they will not
give, sell, use or otherwise divulge any Confidential Information relating to
Seller or its business, including the Recovery Boiler Business, except as
contemplated by the Supply Agreement.

                 (b)  From the date of this Agreement until the Closing, (i)
Purchasers shall restrict the distribution of the Confidential Information to
such of their employees and advisors who need to know such information for the
sole purpose of furthering the transactions contemplated by this Agreement and
(ii) Purchasers shall, in addition, inform each employee or advisor to whom
Confidential Information is disclosed of the restrictions as to the use and
disclosure of Confidential Information and ensure that each such employee or
advisor shall observe such restrictions.

                 (c)  Purchasers agree, covenant and acknowledge that from and
after the Closing Date, they will not disclose, give, sell, use or otherwise
divulge any Confidential Information relating to (i) Seller or its businesses
including the Recovery Boiler Business or (ii) the Retained Shared

Assets except as contemplated by the Intellectual Property License Agreements.

                 (d)  In the event Purchasers or their respective employees,
officers, directors or advisors become legally compelled to disclose any
Confidential Information, Purchasers shall provide Seller with prompt written
notice of such requirement so that Seller may seek a protective order or other
remedy or waive compliance with this Section 10.5.  In the event that such
protective order or other remedy is not obtained, or Seller waives compliance
with this Section 10.5, Purchasers shall furnish only that portion of
Confidential Information which is legally required to be provided and exercise
their best efforts to obtain assurances that appropriate confidential treatment
will be accorded Confidential Information.

                 (e)  The confidentiality and restrictive use obligations under
this Section 10.5 shall not apply to any information that, at the time of
disclosure, is or subsequently becomes available publicly, provided, however,
that such information was not disclosed in breach of this Agreement by
Purchasers or any of their Affiliates, or their respective employees, officers,
directors or advisors.

                 (f)  It is the desire and intent of the parties to this
Agreement that the provisions of this Section 10.5 shall be enforced to the
fullest extent permissible under the laws and public policies applied in each
jurisdiction in which enforcement is sought.  If any particular provisions or
portion of this Section 10.5 shall be adjudicated to be invalid or
unenforceable, this Section shall be deemed amended to delete therefrom such
provision or portion adjudicated to be invalid or unenforceable, such amendment
to apply only with respect to the operation of such Section in the particular
jurisdiction in which such adjudication is made.

                 (g)  Purchasers recognize that the performance of the
obligations under this Section 10.5 are special, unique and extraordinary in
character, and that in the event of the breach by Purchasers, their Affiliates
or their respective employees, officers, directors or advisors of the terms and
conditions of this Section 10.5, Seller shall be entitled, if it so elects, to
institute and prosecute proceedings in any court of competent jurisdiction,
either at law or in equity, to enforce the specific performance thereof by
Purchasers or to enjoin Purchasers, their Affiliates or their respective
employees, officers, directors or advisors from violating the provisions of
this Section 10.5.

offer employment to the persons whose names are set forth on Schedule 4.23(a)
hereto other than those to be retained by Seller as indicated on Schedule
4.23(a).

                 (b)  Except for the employees listed in Schedule 10.6(b),
neither Purchasers nor their Affiliates nor their respective employees,
officers or directors shall, until the later of the Environmental Audit
Acceptance Date and the Antitrust Clearance Date solicit the employment of any
persons whose names are set forth on Schedule 4.23(a), or induce any Person to
engage in such solicitation other than in connection with the transactions
contemplated by this Agreement.

                 (c)  Purchasers hereby covenant and agree that in the event
this Agreement is terminated, they shall not for a period of two (2) years from
the date of such termination offer employment to or hire (as an employee,
independent contractor, consultant or otherwise) any person who was, at any
time during the six-month period prior to the date of such termination an
employee, officer or director of Seller (with respect to the Power Generation
Business), ADC or the Subject Companies.

                 10.7.  Finnish VAT Certification.  FW shall deliver to Seller
at Closing a certificate, for purposes of Finnish transfer taxes, signed by an
authorized officer of Purchasers stating that FW is purchasing the Power
Generation Business as an entirety and presently intends to continue the
operation of such business.

                 10.8.  Exclusive Dealing.  During the period from the date of
this Agreement to the earlier of the Closing Date or the termination of this
Agreement, Purchasers shall not, and shall not permit any of their Affiliates
or their respective officers, directors, employees and advisors to, take any
action to, directly or indirectly, encourage, initiate or engage in
discussions, negotiations, agreements or understandings with any third party
concerning any purchase by Purchasers of the capital stock or the assets of an
entity involved in the power generation business of the type conducted by
Seller if such purchase is reasonably likely to have an adverse impact on
approval of the transactions contemplated hereby under the HSR Act.

                 10.9.  Accounts Receivable.  (a)  FW agrees to use ordinary
and customary efforts consistent with its past practice to (i) attempt to
collect the billed Accounts Receivable set forth in the Final Closing Balance
Sheet, and (ii) perform, in all material respects, all warranty work or other
service obligations under the contract giving rise to Accounts Receivable.
Seller agrees to cooperate, and to cause its employees to cooperate, and
furnish reasonable assistance to FW to collect Accounts Receivable referred to
in the preceding sentence.  After the first anniversary of the Closing Date,
any billed Accounts Receivable set forth in the Final Closing Balance Sheet the
collection of which is precluded on the date FW presents to Seller a
certificate describing Uncollected Receivables (see Section 8.13) by any
applicable statute of limitations expiring after the first anniversary of the
Closing Date shall be treated as if it had been paid in full.

                 (b)  Upon receipt of full payment by Seller of the Uncollected
Receivables described in the certificate presented by FW as set forth in
Section 8.13, FW shall promptly assign in writing to Seller or its designee the
Uncollected Receivables specified in such certificate and shall execute all
documents and take all action reasonable necessary to effect such assignment.
FW will provide Seller with all reasonable necessary available documentation
relating to FW's efforts to collect the Uncollected Receivables and all other
available documentation reasonably necessary in connection with Seller's
collection of any receivables to Seller hereunder.  FW agrees to remit promptly
to Seller any amount received by FW after the date FW submitted the certificate
described above in respect of Uncollected Receivables for which it has received
payment from Seller.


                                   ARTICLE XI

                                  TAX MATTERS

                 11.1.  Tax Liabilities and Benefits.  All Tax liabilities
imposed on the Subject Companies, the Finland Assets or the ADC Assets or for
which the Subject Companies, the Finland Assets or the ADC Assets may otherwise
be liable with respect to Tax periods or portions thereof ending on or before
the Closing Date shall be for the account of and paid by Seller, including,
without limitation, all Taxes imposed on the Subject Companies, or for which
the Subject Companies may be liable, as a result of recognizing income from the
sale of assets that is deemed to occur or other recognition





                                      -94-
<PAGE>   105





of income that is triggered as a result of any election to be made by AIH and
Purchasers pursuant to Sections 338(g) and 338(h)(10) of the Code, any
provision of foreign law analogous to Section 338 of the Code or any provision
of state or local law analogous to Section 338 of the Code; provided, however,
that Seller shall not be responsible for any Taxes attributable to sales or
other transactions (other than the transactions contemplated by this Agreement)
that are not in the ordinary course of business and that occur on the Closing
Date but after the Closing.  Tax liabilities imposed on the Subject Companies,
the Finland Assets and the ADC Assets or for which the Subject Companies, the
Finland Assets or the ADC Assets may otherwise be liable with respect to Tax
periods or portions thereof beginning after the Closing Date shall be for the
account of and paid by Purchaser.  For this purpose, Tax liabilities with
respect to a period which begins on or before and ends after the Closing Date
shall be apportioned between the portion of such period ending on the Closing
Date and the portion beginning on the day after the Closing Date as follows:
(a) in the case of Taxes other than income, profits, gains, sales, use or value
added Taxes, on a per diem basis, (b) in the case of all Taxes based on income,
profits, gains, sales, use or value added, to the portion of such period ending
on the Closing Date as though the taxable year or other taxable period of the
Subject Companies and Seller terminated at the close of business on the Closing
Date and based on accounting methods, elections and conventions that do not
have the effect of distorting the allocation of income and expenses within a
taxable year.

                 11.2.  Tax Returns.  (a)  Seller shall, consistent with prior
year practice, cause AIH to include API and its Subsidiaries located in the
United States in the consolidated U.S. federal income Tax Returns and, to the
extent permitted by applicable law, in any combined, consolidated or unitary
state or local income Tax Returns filed by AIH for all Tax periods or portions
thereof ending on or prior to the Closing Date.  Seller shall also prepare, or
shall cause to be prepared, and thereafter timely file all Tax Returns required
to be filed by or with respect to the Subject Companies, the Finland Assets and
the ADC Assets for all Tax periods ending on or prior to the Closing Date.  All
Tax Returns required to be filed by Seller pursuant to this Section 11.2(a)
shall be prepared on a basis consistent with the Tax Returns filed by or on
behalf of the Subject Companies, the Finland Assets and the ADC Assets for the
preceding Tax period.  In order to facilitate preparation of such Tax Returns,
FW shall, within a reasonable period of time after Seller's written request,





                                      -95-

provide Seller with such information as Seller shall identify that is
reasonably necessary for preparing Tax Returns described in this Section
11.2(a).  Such information shall be submitted in a form consistent with prior
practice.

                 (b)  Purchasers shall prepare, or shall cause to be prepared,

periods beginning on or before and ending after the Closing Date.  All such Tax
Returns shall be prepared on a basis consistent with the Tax Returns filed by
or on behalf of the Subject Companies, the Finland Assets and the ADC Assets
for the preceding Tax periods.

                 (c)  Purchaser shall, or shall cause the Subject Companies to,
prepare and file all Tax Returns required to be filed by the Subject Companies
after the Closing Date for all Tax periods beginning after the Closing Date.
In order to facilitate the preparation of Tax Returns, Seller shall, within a
reasonable period of time after FW's written request, provide Purchaser with
such information as Purchaser shall identify that is reasonably necessary for
preparing Tax Returns described in Section 11.2(b) and this Section, 11.2(c).
Such information shall be submitted in a form consistent with prior practice.

                 (d)  Except as otherwise provided in this Article XI, Seller
shall pay (or reimburse the Subject Companies or Purchaser for paying) and
Purchasers shall pay (or reimburse Seller for paying) the Taxes reportable on
the Tax Returns referred to in Sections 11.2(a), (b) and (c) (and any
subsequent adjustments thereto) to the extent provided in Section 11.1.  Any
reimbursements under this Section 11.2(d) shall be made within ten (10)
Business Days of receipt of written notice from Purchaser or Seller that such
reimbursement is due.

                 11.3.  Indemnification.  (a) Seller and its successors shall
indemnify, defend and hold harmless Purchasers and each of the Subject
Companies and the successors to the foregoing (and their respective
shareholders, officers, directors, employees and agents) on an after-tax basis
against and shall be entitled to any refund of (i) all Taxes resulting from,
arising out of or incurred with respect to, any claims that may be asserted by
any party based upon, attributable to, or resulting from any breach by Seller
of the representations under Section 4.14(c)(ii) or (iv), (ii) all Taxes
imposed on Seller or any corporation or entity (other





                                      -96-
<PAGE>   107





than the Subject Companies) in which Seller or any of its Affiliates has or had
at any time a direct or indirect majority equity interest for any taxable year
or other taxable period, and (iii) all Taxes allocated to Seller pursuant to
Section 11.1 hereof.  FW shall promptly give Seller written notice of all
Taxes, losses, claims and expenses which FW has determined may give rise to a
right of indemnification under this Section 11.3(a), including a computation of
the amount of the required indemnification with sufficient detail and
particularity to enable Seller to reasonably determine the amount of such
required indemnification.

                 (b)      Purchaser and its successors shall indemnify, defend
and hold harmless Seller and its successors (and its shareholders, officers,
directors, employees and agents) on an after-tax basis against, and shall be
entitled to any refund of, all Taxes allocated to Purchaser pursuant to Section
11.1.  Seller shall promptly give Purchaser written notice of all Taxes,
losses, claims and expenses which Seller has determined may give rise to a
right of indemnification under this Section 11.3(b), including a computation of
the amount of the required indemnification with sufficient detail and
particularity to enable Purchaser to reasonably determine the amount of such
required indemnification.

                 (c)      The indemnity provided in this Section 11.3 shall be
the exclusive indemnity of the parties with respect to Taxes.

                 11.4.  Cooperation; Audits.  In connection with the
preparation of Tax Returns and audit examinations relating to the Subject
Companies, the Finland Assets and the ADC Assets by any governmental taxing
authority or administrative or judicial proceedings resulting therefrom,
Seller, Purchasers and the Subject Companies will cooperate fully with one
another, including, but not limited to, the furnishing or making available on a
timely basis of records, personnel (as reasonably required), books of account,
powers of attorney or other materials necessary or helpful for the preparation
of Tax Returns, the conduct of audit examinations or the defense of claims by
taxing authorities as to the imposition of Taxes.  Without limiting the
generality of the foregoing, Seller (and its representatives) shall be entitled
to examine books and records of the Subject Companies, the Finland Assets and
the ADC Assets with respect to any taxable period or portion thereof ending on
or prior to the Closing Date, and shall have reasonable access to personnel of
the Subject Companies to the extent necessary or helpful for purposes of
preparing or amending Tax Returns (including previously filed





                                      -97-
<PAGE>   108





Tax Returns) or obtaining Tax refunds relating to the Subject Companies, the
Seller or its Affiliates.  Seller shall control the conduct of all stages of
any audit or other administrative or judicial proceeding with respect to the
Tax liability of the Subject Companies, the Finland Assets and the ADC Assets
reflected on all Tax Returns with respect to any taxable year or other taxable
period ending on or before the Closing Date, including such Tax liability
reflected on all Tax Returns for any consolidated or combined group of which
Seller and any of the Subject Companies are members with respect to any taxable
year or taxable period which, with respect to the Subject Companies, ends on or
before the Closing Date but which, with respect to any other member of such
consolidated or combined group, ends after the Closing Date.  FW shall control
the conduct of all other audits or other administrative or judicial proceedings
with respect to the Tax liability of the Subject Companies, the Finland Assets
and the ADC Assets.  Subject to such control:

                 (a)  Seller shall give prompt notice to FW of any Tax
         adjustment proposed pursuant to any such audit or other proceeding
         controlled by Seller and shall not enter into any settlement or
         agreement relating to such proposed adjustment which purports to bind
         a Purchaser or the Subject Companies with respect to any Tax period
         ending after the Closing Date without Purchaser's written consent,
         which consent shall not be unreasonably withheld.

                 (b)  Purchaser shall give prompt notice to Seller of any Tax
         adjustment proposed pursuant to any such tax audit or other proceeding
         controlled by Purchaser, which Tax would be for the account of Seller
         pursuant to this Article XI, and shall not enter into any settlement
         or agreement relating to such proposed adjustment without Seller's
         written consent, which consent shall not be unreasonably withheld.

                 11.5.  Section 338 Election.  Seller and FW shall jointly
complete and make an election under Section 338(g) (with respect to the Subject
Companies) and Section 338(h)(10) (with respect to API and its Subsidiaries
included in the AIH affiliated group) of the Code on Form 8023A or in such
other manner as may be required by rule or regulation of the IRS, and shall
jointly make an election in the manner required under any analogous provisions
of state or local law with respect to API and its Subsidiaries included in the
AIH affiliated group as FW shall designate or as shall be required, concerning
the transactions contemplated by this





                                      -98-
<PAGE>   109





Agreement.  FW shall, with the assistance and cooperation of Seller, prepare on
a reasonable basis and in a manner consistent with this Agreement all such
Section 338(g) and Section 338(h)(10) election forms and required attachments
to Form 8023A (and all forms under analogous provisions of state or local law)
in accordance with applicable Tax laws, and FW shall deliver such forms and
related documents to Seller at least ninety (90) days prior to the due date of
filing.  FW shall consult with Seller in preparing such forms and shall not
include any position or information therein that is inconsistent with this
Agreement.  Seller shall deliver to FW, at least forty-five (45) days prior to
the due date of filing, such completed forms as are required to be filed under
Section 338 of the Code (and analogous provisions of state or local law).

                 11.6.  Valuation and Allocation.  Seller and Purchasers agree
to allocate the Purchase Price and Assumed Obligations for purposes of any
Taxes that may be affected by such allocation in accordance with Section 3.6.
Seller and Purchasers will act reasonably and in good faith to reach an
agreement promptly after the Closing on a further allocation of the Purchase
Price and Assumed Obligations for API and its Subsidiaries to categories of
assets as required for purposes of Section 338 under the Code.  Neither FW or
Seller shall unreasonably withhold consent to the manner of valuation or
allocation employed.  If FW and Seller are unable to reach a mutually
acceptable valuation of assets and allocation of Purchase Price and Assumed
Obligations within 120 days after the Closing Date, FW and Seller shall submit
the issue to arbitration by a nationally recognized accounting firm as shall be
mutually acceptable to FW and Seller for resolution of the disagreement within
thirty (30) days, it being agreed that FW and Seller will jointly share the
fees and expenses of such accounting firm.  The valuations and allocations
determined pursuant to this Section 11.6 shall be used for purposes of all
relevant Tax Returns, reports and filings, but shall not be relevant or have
any effect on any other provision of this Agreement, including, without
limitation, on the Preliminary Closing Balance Sheet, the Final Closing Balance
Sheet or any calculation based thereon or the allocation made under Section 3.6
of this Agreement except insofar as these other provisions relate to or affect
Taxes or Tax Returns.

                 11.7.  Tax Sharing Agreements.  Seller covenants and agrees
that as of the Closing Date there shall be no tax sharing or tax allocation
agreements other than this Agreement in effect as between the Subject Companies
or any





                                      -99-
<PAGE>   110





predecessor or affiliate thereof, on the one hand, and Seller or any
predecessors or affiliates thereof, on the other hand, under which any
Purchaser or the Subject Companies could be liable for any Taxes or other
claims of any party after the Closing Date.

                 11.8.  Cooperation; Employment Taxes.  Seller will cooperate
with Purchaser to file all documents necessary and appropriate to secure, to
the extent available, the benefits of Section 3121(a)(1) of the Code and
Section 31.3121(a)(1)-1(b) of the Treasury Regulations promulgated thereunder,
with the result that Purchaser will be treated as a "successor employers" for
purposes of the Federal Insurance Contributions Act provisions in Chapter 21 of
the Code and any comparable or analogous provisions of state unemployment tax
or disability laws.

Party") from and against any and all costs, expenses, losses, damages or
liabilities (including, without limitation, reasonable attorneys' fees,
consultants fees, reimbursements, interest and any penalties) (collectively,
"Losses" and individually, a "Loss") incurred by any Purchaser Indemnified
Party arising out of or relating to:

             (i)  the breach of any representation or warranty (excluding
         any representation or warranty made by Seller pursuant to Section 4.14
         as to which the sole indemnification right shall be pursuant to
         Section 11.3, and excluding any representation or warranty made by
         Seller pursuant to Section 4.21, as to which the sole indemnification
         right shall be pursuant to Section 13.2(a)(iii)) made by Seller in
         this Agreement or in the Schedules or the Exhibits attached hereto;

             (ii)  any claim, including any Environmental Claim,  which may be
         made against a Purchaser Indemnified Party with respect to any
         Excluded Assets or Excluded Liabilities;

             (iii)  (A) any investigation, cleanup, removal, remediation or 
         response action ("Response Action") required by Environmental Law in 
         connection with the actual or alleged presence or Release of 
         Hazardous Materials on Seller Property or Premises on or prior to the
         Closing Date; and (B) any Environmental Claim or violation of any 
         applicable Environmental Law relating to (x) Seller Property or 
         Premises or (y) the operations of Seller or any of its Affiliates 
         (including, without limitation, each Subject Company), its agents, 
         contractors or subcontractors relating to the Power Generation 
         Business, in the case of (x) and (y) above, limited only to such 
         Losses arising from conditions, events or circumstances occurring or 
         existing on or prior to the Closing Date; provided, however, that as 
         used in clause (A) above, a Response Action required by Environmental
         Law shall not require the initiation of an Environmental Claim by any 
         governmental agency or





                                     -101-

         private party and shall include a voluntary Response Action by a
         Purchaser Indemnified Party as long as such Response Action is
         required by applicable Environmental Law;

             (iv)  claims against a Purchaser Indemnified Party arising in
         connection with death, personal injury or other tort, or property
         damage (whether based on statute, negligence, strict liability or any
         other theory) caused by or resulting from, directly or indirectly, the
         manufacture or sale of any product, or the provision of any
         construction, design or other services, by the Seller or any of the
         Subject Companies on or before the Closing Date;

              (v)  except to the extent (A) expressly assumed by Purchasers
         pursuant to this Agreement or required to be assumed by Purchasers by
         operation of non-U.S. Law, (B) relating specifically to the crediting
         of past service pursuant to Section 9.2, (C) as provided in Section
         9.6 with respect to "stop-loss" insurance, (D) reflected on the Final
         Closing Balance Sheet, or (E) arising as a result of the termination
         of the contracts with the individual persons set forth on Schedule
         4.20, (x) any employee benefit plan, program, arrangement, commitment,
         policy or practice of Seller or to which Seller contributes and (y)
         any Employee Benefit Plan or the employment or prospective employment
         by Seller or any Subject Company of any person, in either case
         described in this clause (y), to the extent attributable to
         conditions, events or circumstances occurring or existing on or prior
         to the Closing Date;

             (vi)  claims arising from or relating to Pyropower's interest in
         Multipower, including, without limitation, the litigation referred to
         on Schedule 4.13; and

            (vii)  each matter listed or referred to on Schedule 4.13 and/or
         item 10 of Schedule 4.17 attached hereto (or required to be listed on
         Schedule 4.13) and any other claims and causes of action relating to
         the facts or circumstances giving rise to such matter.

No claim for indemnification may be made by a Purchaser Indemnified Party under
Section 13.2(a)(i) above unless (1) such claim is made prior to the end of the
applicable survival period for such representation and warranty provided in
Section 13.1 above (but the right to indemnification under Section 13.2(a)(i)
with respect to timely claims shall remain





                                     -103-
<PAGE>   114





in full force and effect until such claims are finally resolved) and (2) until
Losses suffered by Purchaser Indemnified Parties exceed two hundred and fifty
thousand US dollars ($250,000) in the aggregate, at which time each Purchaser
Indemnified Party shall have the right to recover an amount equal to all Losses
suffered or incurred by such Purchaser Indemnified Party.  Seller's obligation
to indemnify under Section 13.2(a)(i) shall in no event exceed sixty-five
million U.S. dollars ($65,000,000) in the aggregate and shall survive until the
respective dates set forth in Section 13.1, except for claims of which Seller
has received notice under Section 13.3(c).  Seller's obligation to indemnify
under Section 13.2(a)(iii) shall in no event exceed twenty-two million five
hundred thousand U.S. dollars ($22,500,000) in the aggregate and shall survive
for a period of seven (7) years after the Closing Date, except for claims of
which Seller has received notice under Section 13.3(c) or (e).  Seller's
obligation to indemnify under Section 13.2(a)(iv) shall survive for a period of
five (5) years after the Closing Date, except for claims of which Seller has
received notice under Section 13.3(c).  To the extent Seller assigns Subject
Company Claims and Ahlstrom Insurance Policies make payment to a Purchaser
Indemnified Party, it is understood and agreed that a Loss has been reduced by
the amount of such payment and Seller's obligation to indemnify the involved
Purchaser Indemnified Party shall be reduced accordingly.  To the extent that
the Purchasers have been made whole for any Losses in connection with the
determination of the Adjusted Closing Payment, the Purchasers shall not be
entitled to be indemnified under this Section 13.2.

                 (b)  FW shall defend and hold Seller and its respective
shareholders, officers, directors, employees, agents, representatives and
successors and assigns (each a "Seller Indemnified Party") harmless from and
against any Loss or Losses incurred by a Seller Indemnified Party arising out
of or relating to:

                 (i)  the breach of any representation or warranty made by FW
         in this Agreement or in the Schedules or the Exhibits attached hereto;

             (ii)  any claim made against a Seller Indemnified Party arising
out of or resulting from the Assumed Obligations; and

            (iii)  any claims asserted against any Seller Indemnified Party
         from the termination of the employment by a Purchaser or a Subject
         Company or any other Affiliate





                                     -104-
<PAGE>   115





         of FW of any employee of any of the Subject Companies or of any other
         individual whose name is set forth on Schedule 4.23(a) (other than
         those noted as being retained by Seller and other than those employees
         of ADC not transferred to API pursuant to Section 8.11(c)) on or after
         the Closing Date.

No claim for indemnification may be made by a Seller Indemnitee under Section
13.2(b)(i) above unless and until Losses suffered by Seller Indemnified Parties
exceed two hundred and fifty thousand US dollars ($250,000) in the aggregate,
at which time each Seller Indemnified Party shall have the right to recover an
amount equal to all Losses suffered or incurred by such Seller Indemnified
Party.  Purchasers' obligations to indemnify under Section 13.2(b)(i) shall in
no event exceed fifteen million U.S. dollars ($15,000,000) in the aggregate.

                 13.3.  Indemnification Procedure.  (a)  Promptly after the
incurrence of a Loss or Losses by the party seeking indemnification (the
"Indemnified Party") which might give rise to indemnification hereunder (other
than Losses for which Seller has agreed to indemnify the Purchaser Indemnified
Parties under Section 13.2(a)(vii) which shall be governed by Section 13.4),
the Indemnified Party shall deliver to the party from which indemnification is
sought (the "Indemnifying Party") a certificate (the "Certificate"), which
Certificate shall:

                 (i)  state that the Indemnified Party has paid or properly
         accrued Losses, or anticipates that it will incur liability for Losses
         for which such Indemnified Party is entitled to indemnification
         pursuant to this Agreement; and

             (ii)  specify in reasonable detail each individual item of Loss
         included in the amount so stated, the date such item was paid or
         properly accrued, the basis for any anticipated liability and the
         nature of the misrepresentation, breach of warranty or breach of
         covenant or claim to which each such item is related and the
         computation of the amount to which such Indemnified Party claims to be
         entitled hereunder.

                 (b)  In case the Indemnifying Party shall object to the
indemnification of an Indemnified Party in respect of any claim or claims
specified in any Certificate, the Indemnifying Party shall, within thirty (30)
days after receipt by the Indemnifying Party of such Certificate, deliver to
the Indemnified Party a written notice to such





                                     -105-
<PAGE>   116





effect and the Indemnifying Party and the Indemnified Party shall, within the
thirty (30) day period beginning on the date of receipt by the Indemnified
Party of such written objection, attempt in good faith to agree upon the rights
of the respective parties with respect to each of such claims to which the
Indemnifying Party shall have so objected.  If the Indemnified Party and the
Indemnifying Party shall succeed in reaching agreement on their respective
rights with respect to any of such claims, the Indemnified Party and the
Indemnifying Party shall promptly prepare and sign a memorandum setting forth
such agreement.  Should the Indemnified Party and the Indemnifying Party be
unable to agree as to any particular item or items or amount or amounts, then
the Indemnified Party and the Indemnifying Party shall submit such dispute to
the arbitration tribunal as provided in Section 14.11.

                 (c)  Promptly after the assertion by any third party of any
claim against any Indemnified Party that, in the judgment of such Indemnified
Party, may result in the incurrence by such Indemnified Party of Losses for
which such Indemnified Party would be entitled to indemnification pursuant to
this Agreement, such Indemnified Party shall deliver to the Indemnifying Party
a written notice describing in reasonable detail such claim and such
Indemnifying Party may, at its option, assume the defense of the Indemnified
Party against such claim (including the employment of counsel, who shall be
reasonably satisfactory to such Indemnified Party, and the payment of
expenses).  Any Indemnified Party shall have the right to employ separate
counsel in any such action or claim and to participate in the defense thereof,
but the fees and expenses of such counsel shall not be at the expense of the
Indemnifying Party, unless (i) the Indemnifying Party shall have failed, within
a reasonable time after having been notified by the Indemnified Party of the
existence of such claim as provided in the preceding sentence, to assume the
defense of such claim, (ii) the employment of such counsel has been
specifically authorized in writing by the Indemnifying Party, which
authorization shall not be unreasonably withheld, or (iii) the named parties to
any such action (including any impleaded parties) include both such Indemnified
Party and the Indemnifying Party and such Indemnified Party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to the Indemnifying Party which are not available to, or the
assertion of which would be adverse to the interests of, the Indemnified Party.
No Indemnifying Party shall be liable to indemnify any Indemnified Party for
any settlement of any such action or claim effected without the prior written
consent of the Indemnifying Party but if settled with the written consent of





                                     -106-
<PAGE>   117





the Indemnifying Party, or if there be a final judgment for the plaintiff in
any such action, the Indemnifying Party shall indemnify and hold harmless each
Indemnified Party from and against any loss or liability by reason of such
settlement or judgment.

                 (d)  Claims for Losses specified in any Certificate to which
an Indemnifying Party shall not object in writing within thirty (30) days of
receipt of such Certificate, claims for Losses covered by a memorandum of
agreement of the nature described in paragraph (b), claims for Losses the
validity and amount of which have been the subject of arbitral determination as
described in paragraph (b) and claims for Losses the validity and amount of
which shall have been the subject of a final arbitral determination as
described in paragraph (c) are hereinafter referred to, collectively, as
"Agreed Claims".  Within ten (10) Business Days of the determination of the
amount of any Agreed Claims, the Indemnifying Party shall pay to the
Indemnified Party an amount equal to the Agreed Claim by wire transfer in
immediately available funds to the bank account or accounts designated in
writing by the Indemnified Party not less than one (1) Business Day prior to
such payment.

                 (e)  Notwithstanding the foregoing, the procedures in this
Section 13.3(e) shall apply with respect to any Response Action under Section
13.2(a)(iii).

                 (i)      Promptly after the assertion of an Environ-mental
Claim against any Purchaser Indemnified Party that, in the judgment of such
Purchaser Indemnified Party, may result in a Response Action under Section
13.2(a)(iii), such Purchaser Indemnified Party shall deliver to Seller a
written notice describing in reasonable detail such claim.  Such Purchaser
Indemnified Party shall promptly provide Seller with copies of notices,
pleadings, documents or other available appropriate information regarding such
claim and otherwise shall keep Seller fully advised of the progress of such
claim, including without limitation, advance notice of possible settlements,
and Seller shall have the right to reasonable access to the relevant property
and to relevant documents or records.  Seller shall not be liable to indemnify
any Purchaser Indemnified Party for any settlement of any such Environmental
Claim which was entered without the prior written consent of Seller, which
consent shall not be unreasonably withheld, provided, however that if Seller
does not agree that such Environmental Claim is subject to the indemnification
provisions of Section 13.2(a)(iii) then





                                     -107-
<PAGE>   118





Purchaser Indemnified Party shall be free to settle such claim without Seller's
consent.

                 (ii)     Prior to initiating any Response Action covered by
Section 13.2(a)(iii), other than in response to an Environmental Claim and
other than where events or circumstances warrant immediate action to protect
human health or safety or the environment, Purchaser Indemnified Party shall
consult with Seller.  In the latter case, Purchaser Indemnified Party shall
consult with Seller as soon as reasonably possible.

                 (iii) Purchaser Indemnified Party shall have the right to
manage and control all discussions with relevant governmental or other
authorities and all proceedings regarding such Response Actions under Section
13.2(a)(iii), including without limitation any required investigation, response
or remediation, provided, however that Seller and an environmental consultant
engaged by Seller ("Seller's Consultant") shall be permitted to review and
comment on all relevant documents, plans and reports prior to submission, if
any, to the appropriate governmental authorities or if no submission is
necessary, within a reasonable time prior to commencement of such Response
Action.  Purchaser Indemnified Party shall consider in good faith for inclusion
in such documents, plans and reports all such comments.  Seller and Seller's
Consultant also shall be permitted to monitor the Response Action and to review
appropriate test results, lab analyses, reports, drafts and other information
generated in undertaking and completing any such Response Action, and to have
access to split samples for laboratory testing at Seller's expense.  Purchaser
Indemnified Party and any of its agents conducting Response Action shall
generally keep Seller and Seller's Consultant informed of all Response Action
and shall be available at reasonable times to respond to all reasonable
inquiries regarding such Response Action.

                 (iv)     Losses incurred by Purchaser Indemnified Party shall
be enumerated in invoices submitted not more frequently than once each calendar
month and not less frequently than once every calendar quarter.  The invoice
shall include reasonable supporting documentation explaining the nature and
basis of such Losses and detailed time and rate information and expense reports
of any third party consultants, contractors or counsel.  Seller shall make full
payment of each invoice within thirty (30) days of receipt of such invoice,
unless Seller provides prior written notice that it is disputing the amount
thereof.

                 13.4.  Litigation Matters.  Seller shall have the sole and
exclusive right and obligation to contest, defend, litigate or settle any of
the matters listed or referred to in Schedule 4.13; provided, however that
Seller shall not have the right to settle any matter without the prior written
consent of FW unless such settlement only involves the payment of money and in
connection therewith FW and its Affiliates receive a full and unconditional
release from the plaintiff.  After the Closing Date FW agrees to cause any
Purchaser and each Subject Company to cooperate in all reasonable respects with
Seller in connection with such matters provided that such cooperation does not
materially interfere with the business and operations of the Power Generation
Business as conducted by FW and its Affiliates after the Closing Date.

                 (d)  The arbitration tribunal shall not have power to award

invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the

party.  Upon such determination that any provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the parties as
closely as possible in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled.

         more than two years after the date on which services or materials were
         furnished by APCSI, up to a maximum of $3,000,000;

         to contain a waiver of consequential damages, up to a maximum of
         $4,000,000; provided, however, that the indemnification provided by 
         this clause (viii) shall be in addition to, and not any limitation 
         of, the obligation of Seller to indemnify the Purchaser Indemnified 
         Parties under Section 13.2(a)(iv) of the Purchase Agreement.

                     follows:

                 7.1  EVT Agreement.  In addition to any other obligations
which Seller may have with respect to Non-Conveyed Contracts under the Purchase
Agreement, Seller shall take the following steps and actions with respect to
the agreement between Seller and EVT Energie - und Verfahrenstechjk GmbH
("EVT") as amended and restated on November 14, 1993 (the "EVT Agreement"):

                          (i)  Seller shall promptly inform Purchaser of any
                 notices, communications, discussions or any other information,
                 from whatever source, obtained by Seller with respect to the
                 EVT Agreement or EVT's activities thereunder.  Seller shall
                 immediately inform Purchaser if it becomes aware or has any
                 reason to believe that EVT has breached any of its obligations
                 or covenants under the EVT Agreement;

                          (ii)  Seller shall not contact, correspond or

                 Agreement without prior consultation with Purchaser;





                                     -5-
<PAGE>   6





                          (iii)  Seller shall follow Purchaser's directions
                 with respect to the EVT Agreement, including, without
                 limitation, sending notices of default under the EVT Agreement
                 and initiating and pursuing such legal actions or proceedings,
                 with such legal counsel, as Purchaser, in consultation with
                 Seller, but in Purchaser's sole discretion, shall direct; and

                          (iv)  In the event Purchaser instructs Seller to
                 initiate litigation regarding Seller's rights under the EVT
                 Agreement, Purchaser will pay all costs and fees relating
                 thereto, including attorneys fees and disbursements, and any
                 other Losses; provided, however, that Purchaser will not be
                 responsible for costs, fees or any damages relating to claims
                 made against Seller arising out of or resulting from Seller's
                 pre-Closing activities or any post-Closing actions taken by
                 Seller without prior consultation and approval of Purchaser.

                 7.2  Sulzer Agreement.  Notwithstanding anything to the
contrary in this Agreement or the Purchase Agreement, Seller and Purchaser
agree that with respect to the License and Technical Collaboration Agreement
between A. Ahlstrom Osakeyhtio and Sulzer Brothers Limited ("Sulzer") dated as
of November 30, 1975 ("Sulzer Agreement"), Purchaser agrees to promptly
reimburse Seller for any annual minimum fees and fixed remuneration actually
made to Sulzer by Seller under the terms of the Sulzer Agreement, up to a
maximum amount equal to $55,000.

                 7.3      Shared Assets.  Schedule 4.32.III sets forth a
tentative list of Shared Assets relating to computer hardware, software,
telecommunications and other information systems.  Seller and Purchaser agree
that promptly, but in no event more than 30 days, after the Closing members of
the Shared Asset task force (or their designees) will meet to evaluate the
computer hardware, software, telecommunications and other information systems,
equipment, data and technology used by the Power Generation Business (the
"Information Systems") and will determine whether any Information Systems are
used by both the Power Generation Business and Seller's other businesses
("Shared Information Systems").  The task force will conduct similar activities
with regard to the library at Varkaus.





                                     -6-
<PAGE>   7





                 To the extent any Shared Information Systems are determined to
exist, the Shared Assets task force will determine which party is the primary
user of such Shared Information Systems (or portions thereof in the event they
can be split without materially altering the utility of the system) and
Purchaser will obtain from Seller or third parties, the appropriate assignments
of proprietary rights, assignments of contract rights, licenses and such other
legal documentation as may be necessary to transfer any license rights to or
vest legal title of the Shared Information Systems in the name of the primary
user and to permit the other user to enjoy such rights in the Shared
Information Systems as if it were the owner or licensee.

                 7.4      Trademarks.  Unless otherwise requested by Purchaser,
upon expiration of the Trademark License Agreement, Seller shall cancel or
otherwise terminate any trademark registration or application for any trademark
registration owned by Seller which incorporates or includes the name or mark
AHLSTROM along with a mark or term assigned, or to be assigned, to Purchaser,
including, without limitation, AHLSTROM PYROFLOW and AHLSTROM PYROPOWER.

                 In addition to any of Seller's obligations under Section 8.10
of the Purchase Agreement, Seller shall take all steps reasonably requested by
Seller to obtain or assist in obtaining recordation, in the trademark office of
Japan, of the assignment and transfer of the trademark application for
PYROFLOW, including, without limitation, restricting the goods and services
covered under the trademark registration for "AHLSTROM PYROFLOW" in Japan (by
excluding therefrom coverage of goods and services related to the Power
Generation Business) and permitting Purchaser to file unopposed new
applications for registration of "PYROFLOW" in Japan in its own name, provided,
however, that Seller shall not be liable for any adverse effects, whether as to
title, validity or enforceability, on such application arising from any action
taken by Purchasers to record transfer or to proceed with registration.  In
connection with the foregoing, Seller shall have the right not to comply with
any proposed course of action other than those set forth above that would
materially adversely affect its other Marks or applications.

                 7.5      Patents.         It is acknowledged by the parties
that inaccuracies and omissions may exist in Schedule 4.17 attached to the
Purchase Agreement and any supplements thereto, with respect to the identifying
numbers, patent and patent application titles or other identifying information
regarding the relevant patents filed or issued in the various jurisdictions.
Promptly, but in no event later than 60 days after Closing (unless with consent
of Purchaser), the parties shall jointly conduct an audit of Seller's patent
files, records, databases and information pertaining to the Ahlstrom Patent
families assigned and transferred or to be assigned and transferred to
Purchaser under the Purchase Agreement to verify and, if necessary, correct the
information set forth in Schedule 4.17.  Concurrently, the parties shall make
arrangements to transfer custody of such files to Purchaser.

                 Seller agrees to provide any and all necessary assistance as
may reasonably be requested by Purchaser in conducting said audit, including,
without limitation, making available necessary personnel, information and
materials, all at no cost to Purchaser.  In addition, Seller agrees to execute
and assist in the formal recordation of any additional assignments or transfers
of patents or patent applications necessary to correct inaccuracies contained
in any patent and patent application assignments or transfers listed on
Schedule 4.17.  In the event any of the patent title ownership information in
Schedule 4.17 with respect to a patent relating to the Power Generation
Business is inaccurate and such title is not held by Seller or a Subject
Company, Seller will take all possible steps to obtain assignments or transfers
to Purchaser of said patents or application from the record or beneficial title
owner.

                 7.6.     Schedules.  Attached hereto as Exhibit C are revised
                   Schedules to the Purchase Agreement.

                 7.7      Environmental.  (a)  Seller hereby agrees that the
repair or replacement of the sewage and drainage systems beneath Plant A and F
in Sosnowiec, Poland constitutes Compliance Costs and agrees to indemnify
Purchaser for the cost of the replacement or repair thereof in accordance with
good engineering practice after the Closing Date.  Whether or not costs and
expenses that may be incurred for repair of the subsidence at Plant A or for
repair or replacement of concrete floors at Plants A and F in Sosnowiec, Poland
are covered by the Environmental Indemnity in Section 13.2(a)(iii) of the
Purchase Agreement shall be determined at or about such time as the repairs or
replacement are undertaken.

                 (b)  It is acknowledged by Purchaser and Seller that the
categorization of costs by the Consultant in its





                                     -7-

final audit report as Compliance Costs or Future Expected Costs shall not be
binding on the parties or any tribunal in determining whether a particular cost
(including without limitation (i) the costs of repairing concrete floors or
subsidence in Poland and (ii) the costs of installing a wastewater treatment
plant in Karhula) is, or is not, covered by the Environmental Indemnity.
Capitalized terms used in this paragraph 7.7 shall have the same meaning as in
Exhibit F to the Purchase Agreement.

                 7.8      Contract Reviews.  Attached hereto as Exhibit D is a
copy of the agreements reached between Seller and Purchaser as part of the
contract review process outlined in Section 8.20 of the Purchase Agreement.
Purchaser and Seller agree that (1) the adjustments reflected therein will be
the basis for all calculations relating to Contribution I and the Backlog as
contemplated by Section 3.7 of the Purchase Agreement and (2) the reserves and
adjustments reflected therein will be reflected in the Preliminary Closing
Balance Sheet and the Final Closing Balance Sheet.  All other commentary
included in Exhibit D beyond the amounts of agreed adjustments (which agreed
adjustments include: the contemplated calculation of foreign exchange one
Business Day prior to the Closing Date; the elimination of the double counting
of Contribution I in certain specified projects; the elimination of
inconsistencies in transfer pricing for certain specified projects; and
identified reserves with respect to the particular projects to which such
reserves are applicable, all as set forth in Exhibit D, e.g., reserves
described in Ahlstrom project number 39834 listed as item 19 on page 10 of
Exhibit D, including, but not limited to, the descriptions of allowed
reductions for bona fide warranty costs and no reserve increases) including,
but not limited to, statements of fact or assumptions supporting either party's
position, shall not constitute a representation or warranty (except that, with
respect to the Siam Paper project (Ahlstrom project number 39822), Seller
represents that the Credit Agreement has been signed), or provide the basis for
any further adjustments or reserves pursuant to this Agreement and the Purchase
Agreement.  Purchaser agrees that it has been made whole for any Losses for
purposes of Section 13.2 of the Purchase Agreement to the extent that the
reserves and adjustments referred to in clause (2) above are reflected in the
Preliminary Closing Balance Sheet and the Final Closing Balance Sheet.

                 7.9      Multipower.  To the extent that the Pyropower
Corporation's 20% share in the gross proceeds





                                     -8-

from the disbursement of funds to Multipower Associates from Banque Paribas
resulting from the acceleration of the payment of $20 million due to Multipower
Associates under the letter of credit issued by said bank exceeds $3.1 million,
Seller agrees to pay the amount of such excess within 5 business days after the
receipt thereof.  Seller agrees to, and agrees to cause its affiliates to, keep
Purchaser informed of the status of the payment referred to above and provide
Purchaser with such information as it or its counsel may reasonably request
with respect thereto and for Purchaser to verify the amount of such payment.

                 7.10  APCSI Warranty Claims.  (a)  Promptly after receipt
thereof, Purchaser agrees to cause APCSI to notify Seller of any written
warranty claims made by a customer of APCSI for which Seller has agreed to
indemnify Purchaser pursuant to Section 5(a)(vi) or (vii) of this Agreement
(the "APCSI Warranty Claims").  Purchaser also agrees to (i) cause APCSI to
notify Seller before incurring any out-of-pocket costs relating to any APCSI
Warranty Claims, (ii) to permit Seller to verify the APCSI Warranty Costs (as
hereinafter defined) and (iii) to the extent reasonably practicable, meet with
a representative of Seller to consult on the scope and nature of the work to be
performed by Purchaser to satisfy such APCSI Warranty Claims.  In addition,
Seller shall be entitled to contact and meet with the customers which have the
right to assert a warranty claim against APCSI which, if asserted, would be an
APCSI Warranty Claim, to attempt to liquidate such warranty claims; provided,
however, that a representative of Purchaser shall be present during each such
conversation or meeting and Purchaser shall approve each and every liquidation
of a warranty claim by Seller, such approval not to be unreasonably withheld.
For purposes of this Agreement, APCSI Warranty Costs shall include materials,
labor, capital costs, depreciation, indirect costs, overhead and a reasonable
mark-up for selling, general and administrative expenses.

                 (b)  In the event that Seller believes that the APCSI Warranty
Costs were not reasonably incurred in connection with any APCSI Warranty Claim,
Seller may refer such dispute for resolution in accordance with the provisions
of Section 14.11 of the Purchase Agreement provided that Seller reimburses
Purchaser for such APCSI Warranty Costs prior thereto.  The arbitrator will be
deemed to have ruled in favor of Purchaser if it finds that the APCSI Warranty
Costs incurred were not unreasonable in light of





                                     -9-

all the circumstances relating to such APCSI Warranty Claim.

                 7.11  Mt. Poso.  Seller agrees to use commercially reasonable
efforts (but at no material cost to Seller or its Affiliates) in its capacity
as a limited partner of Mt. Poso Cogeneration Company ("Owner"), to cause Owner
to enter into an amendment to the Amended and Restated Operation and
Maintenance Agreement dated as of November 30, 1990 (the "Mt. Poso O&M
Agreement") by and between Pyro-Pacific Operating Company and Owner
substantially in the form of Exhibit E attached hereto (the "Mt. Poso
Amendment") as soon as possible after the Closing Date.  Purchaser agrees to
indemnify Seller for all Losses suffered by Seller as a result of the failure
of Pyro Pacific to execute the Mt. Poso Amendment without the provisions of the
last sentence of Section 6.3(a) and Section 6.3(b) thereof attributable to acts
or failures to act on the part of POSCO; provided, however, that Purchaser
shall have no obligation to indemnify Seller under this Section 7.11 if any of
the other parties refuse to execute the Mt. Poso Amendment with or without the
provisions of the last sentence of Section 6.3(a) and Section 6.3(b) included
therein (an "Owner Refusal to Execute").  Seller shall indemnify Purchaser to
the extent as if it were set forth in Section 13.2(a)(vi) of the Purchase
Agreement and in the manner provided in Section 13.4 of the Purchase Agreement
for all Losses incurred in excess of $5,000,000 (i) in the event of an Owner
Refusal to Execute or (ii) notwithstanding the execution of the Mt. Poso
Amendment, the assertion of a claim or the institution of any action or
proceeding against Purchaser or any Affiliate, in each case, arising out of or
in any manner relating to breach of fiduciary duty alleged by limited partners
in Pyro Pacific in connection with bonus payments under the Mt. Poso O&M
Agreement.

                 7.12  Hismelt.  Seller agrees to use commercially reasonable
efforts (but at no material cost to Seller) to consummate the transactions
contemplated by the Memorandum of Understanding attached hereto as Exhibit F.

                 8.  APKK Closing.  Purchaser shall be entitled to withhold
$600,000 (the "APKK Holdback") from the Purchase Price payable to Seller at the
Closing, which amount represents one-half of the portion of the Purchase Price
allocated to the APKK Stock.  Promptly following the Closing, Seller agrees to
take all actions necessary to perfect the transfer of the APKK Stock to Foster
Wheeler Netherlands





                                    -10-
<PAGE>   11





C.V. ("FW Netherlands"), including, without limitation, holding a meeting of
the Board of Directors of APKK to approve such transfer.  Upon completion of
the transfer of the APKK Stock to FW Netherlands (the "APKK Transfer"), Seller
shall cause FW Netherlands to pay the APKK Holdback to Seller by wire transfer
of immediately available funds to an account designated by Seller.  In the
event that the APKK Stock is not transferred to FW Netherlands within thirty
(30) days after the Closing Date, Purchaser shall be entitled to retain the
APKK Holdback and Seller shall pay to Purchaser no later than the thirty-fifth
(35th) day after the Closing Date, by wire transfer of immediately available
funds to an account designated by Purchaser, an amount equal to $600,000, being
the other half of the Purchase Price allocable to the APKK Stock.

                 9.       Purchase Price.  Purchaser and Seller agree that
Exhibit G attached hereto is the calculation of the Closing Payment pursuant to
Section 3.1(b) of the Purchase Agreement.

                 10.  Bioflow.  Purchaser and Seller hereby agree that
notwithstanding anything to the contrary set forth in Section 8.19 of the
Purchase Agreement, the Bioflow Stock will not be transferred to Purchaser at
the Closing and Purchaser shall be entitled to withhold US $50,000 from the
Closing Payment.  Promptly after the Closing, Seller agrees to comply with the
provisions of the Cooperation Contract dated June 28, 1991 together with the
appended contracts thereto (the "Sydcraft Agreement") with respect to a
transfer of the Bioflow Stock to Purchaser and to use commercially reasonable
efforts to transfer the Bioflow Stock to Purchaser.  Without limiting its
obligations under the Sydcraft Agreement, Seller further agrees as follows:

                 (a)  Seller shall notify Sydkraft Aktiebolag ("Sydkraft") of
         the transactions contemplated herein and request Sydkraft's consent to
         the transfer to Purchaser of the Bioflow Stock and of Seller's rights,
         duties and obligations under the Sydcraft Agreement.

                 (b)  If Sydkraft consents to such transfer, Seller shall
         promptly transfer the Bioflow Stock to Purchaser in accordance with
         the procedures and against receipt of the consideration specified in
         the Purchase Agreement.

                 (c)  If Sydkraft does not consent within 30 days after the 
         Closing or such later date as may be





                                    -11-
<PAGE>   12





         extended by Purchaser, Seller shall pay Purchaser an agreed upon
         amount for the Bioflow Stock in immediately available funds within 15
         days after the expiration of such period; provided that if Purchaser
         and Seller do not agree on an amount to be paid to Seller within such
         15 day period, such amount shall be determined by arbitration pursuant
         to Section 14.11 of the Purchase Agreement.  Seller further agrees to
         assign and transfer to Purchaser all residual rights under the Bioflow
         Agreement either as a result of negotiations with Sydkraft or the
         termination by Sydkraft of the Bioflow Agreement pursuant to Section
         14.2.1 thereof.

                 (d)  Seller further agrees that if, as a result of the
         termination of the Bioflow Agreement or for any other reason permitted
         under the Sydcraft Agreement, Sydkraft exercises its right to buy out
         the Bioflow Stock, Seller shall not consummate any such sale without
         the prior written consent of Purchaser;
                                        provided, however, that if Purchaser
         has not consented to such transaction within 15 days of the occurrence
         of the event which triggered the exercise of Sydkraft's right to
         purchase the Bioflow Stock, the purchase price for such Bioflow Stock
         shall be determined by arbitration in accordance with Article 15 of
         the Sydcraft Agreement.  Upon the consummation of any sale of Bioflow
         Stock pursuant to this Section 10, Seller shall wire transfer in
         immediately available funds to Purchaser the excess, if any, of the
         amount paid by Sydkraft for the Bioflow Stock over the amount withheld
         pursuant to this Section 11 promptly after receipt thereof.

                 11.      Miscellaneous.  (a)  Purchasers acknowledge and agree
that the Negotiated Purchase Price Adjustments (as hereinafter defined), the
indemnity provided in Section 5 of this Agreement (to the extent such
indemnities are fulfilled by Seller) and the adjustments agreed by Purchaser
and Seller reflected in the adjusted Balance Sheet or booked by the units in
their September accounts, make the Purchasers whole for any Losses incurred
solely in connection therewith for purposes of Section 13.2 of the Purchase
Agreement and Purchasers shall not be entitled to be indemnified under Section
13.2 with respect thereto.  For purposes of this Agreement, "Negotiated
Purchase Price Adjustments" shall mean (1) an increase to the Purchase Price of
US $300,000 as a result of the License and Technical Assistance Agreement dated
as of April 1, 1975 by and between Seller and Combustion Engineering, Inc.
becoming an Excluded Contract, (2) a reduction of the Purchase Price of US
$800,000 as a result of POSCO Panther Creek, Inc. being eliminated as a Subject
Company, (3) a reduction of the Purchase Price of US $5,000,000 as a result of
the Mt. Poso Amendment and (4) a reduction of the Purchase Price of US
$3,500,000 for costs and risks associated with a proposal to construct two 250
megawatt boilers in Puerto Rico.

                 (b)      Seller or one of its Affiliates will assume the
obligation of API to James D. Murphy under the Ahlstrom Pyropower, Inc.
Deferred Compensation Plan, dated January 28, 1994 ("DCP"), calculated as of
Closing in accordance with the terms of such Plan, which calculation will be
agreed upon between Seller and Purchaser and which amount will be approximately
$268,000, and in connection therewith, Seller will receive a transfer (or
credit) of an equal amount in cash from FW at the Closing.  Seller hereby
agrees to indemnify and hold Purchaser and the Subject Companies harmless from
all Losses relating to the DCP.

                 Purchaser consents to the distribution by API prior to Closing
of certain amounts previously deferred by employees out of bonuses with respect
to years prior to 1995.

                 (c)      Purchaser agrees to fulfill its obligations under
Section 10.4(a) of the Purchase Agreement on or prior to October 31, 1995.

                 12.      Successors and Assigns.  The terms and conditions of
this Agreement shall inure to the benefit of and be binding upon the respective
successors of the parties hereto.

                 13.      Counterparts.  This Agreement may be executed in one
or more counterparts, each of which shall for all purposes be deemed to be an
original and all of which shall constitute the same instrument.

                 14.  Headings.  The headings of the Articles, Sections and
paragraphs of this Agreement are inserted for convenience only and shall not be
deemed to constitute part of this Agreement or to affect the construction
hereof.

                 15.  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (OTHER THAN WITH
RESPECT TO PRINCIPLES OF CONFLICTS OF LAWS THEREUNDER (EXCEPT SECTION





                                    -12-

5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW) AND OTHER THAN WITH RESPECT TO
ANY ISSUE OF ARBITRATION THAT MAY BE GOVERNED BY THE LAWS OF THE UNITED STATES,
AS TO WHICH THE FEDERAL ARBITRATION ACT, TITLE 9, UNITED STATES CODE, AND THE
1958 UNITED  NATIONS CONVENTION ON THE RECOGNITION AND ENFORCEMENT OF FOREIGN
ARBITRAL AWARDS SHALL APPLY).

                 16.  Disputes.  Except as otherwise expressly provided in this
Agreement, any dispute, controversy or claim arising out of, relating to or in
connection with this Agreement, including any question regarding its existence,
validity or termination, or regarding a breach thereof, shall be referred to,
and finally settled in accordance with Section 14.11 of the Purchase Agreement.

                 17.  Severability.  If any provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law or public
policy, all other provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner adverse to any
party.  Upon such determination that any provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the parties as
closely as possible in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled.

                 18.  Purchase Agreement Not Otherwise Amended.  Terms and
provisions of the Purchase Agreement not amended hereby shall continue to
remain in full force and effect.

                 IN WITNESS WHEREOF, each of Purchaser and Seller has caused
this Agreement to be executed on its behalf by its duly authorized Officer.
