                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  ORGANIZATION AND BASIS OF PRESENTATION

    Pioneer Americas Acquisition Corp. ("Pioneer") was incorporated in Delaware
on March 6, 1995 ("Inception").  Pioneer is 100% owned by Pioneer Companies,
Inc. ("PCI"). The consolidated financial statements include the accounts of
Pioneer and its subsidiaries (collectively referred to as the "Company").  All
significant intercompany balances and transactions have been eliminated in
consolidation.

BASIS OF PRESENTATION EFFECTIVE APRIL 20, 1995

    On April 20, 1995, pursuant to a Stock Purchase Agreement, dated as of
March 24, 1995  (the "Acquisition Agreement"), by and among PCI, Pioneer, and
the holders of the outstanding common stock and other common equity interests
(the "Sellers") of Pioneer Americas, Inc. (the "Predecessor Company"), Pioneer
acquired all of such stock and interests (the "Acquisition") for a purchase
price of approximately $176 million.  The Acquisition has been accounted for as
a purchase transaction and, accordingly, the consolidated financial statements
subsequent to April 20, 1995 reflect the purchase price, including transaction
costs, allocated to tangible and intangible assets acquired and liabilities
assumed, based on their estimated fair values as of April 20, 1995.

     The consolidated balance sheet as of June 30, 1996, the statements of
operations as of and for the three- and six-month periods ending June 30, 1996
and 1995 and the statements of cash flows as of and for the six months ended
June 30, 1996 and 1995 are unaudited and reflect all adjustments, consisting of
normal recurring items, which management considers necessary for a fair
presentation.  Operating results for the first six months of 1996 are not
necessarily indicative of results to be expected for the year ending December
31, 1996.

    Certain information and disclosures normally included in the notes to the
financial statements have been condensed or omitted as permitted by the rules
and regulations of the Securities and Exchange Commission.  The accompanying
unaudited financial statements should be read in conjunction with the financial
statements contained in the Annual Report on Form 10-K for the year ended
December 31, 1995.

    On February 2, 1996, the acquisition of Kemira Water Treatment, Inc.
("KWT"), including certain royalty and license agreements, from a subsidiary of
Kemira Oy of Finland ("Kemira") was completed.  The purchase price was
approximately $9.6 million, of which $1.6 million was paid in cash and $8.0
million in a note issued to Kemira.  The $8.0 million note bears an interest
rate equal to LIBOR plus 1.2%.  The principal on the note is payable in four
equal installments on March 31, 2000, March 31, 2001, March 31, 2002 and
December 31, 2002, and interest is payable annually on December 31.  KWT
produces specialty and commodity inorganic coagulants, including polyaluminum
chloride, aluminum sulfate, sodium aluminate and ferric sulfate, at its plant
in Savannah, Georgia for sale to the water treatment market in the eastern
United States and the Caribbean.   The purchase of KWT has been accounted for
as a purchase transaction and, accordingly, the consolidated financial
statements subsequent to February 2, 1996 reflect the purchase price, including
transaction costs, allocated to tangible and intangible assets acquired and
liabilities assumed, based on their estimated fair values as of February 2,
1996, and include the results of KWT subsequent to such date.

    KWT is wholly-owned by Kemwater North America Company ("Kemwater"), fifty
percent of the common stock of which is held by PCI and fifty percent of the
common stock of which is held by a subsidiary of Pioneer.  The Company also
owns all of the outstanding shares of Kemwater's preferred stock.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     The following discussion and analysis should be read in conjunction with
the financial statements and the notes thereto.

     This item will discuss and analyze the financial condition of the Company
at June 30, 1996 and the results of operations of the Company for the three
months and six months ended June 30, 1996 in comparison with the combined
operations of the Company and the Predecessor Company for the comparable 1995
periods. The following table sets forth certain operating data of the Company
and the Predecessor Company for the periods indicated.  For comparative
purposes the Company's results of operations for the three months ended June
30, 1995 include the Predecessor Company's operating results from April 1, 1995
through April 20, 1995, and the Company's operating results for the six months
ended June 30, 1995 include the Predecessor Company's operating results from
January 1, 1995 through April 20, 1995.  The Predecessor Company's operating
results for both periods exclude $1.0 million of transaction costs related to
the Acquisition.  The Company believes that this provides a meaningful basis
for comparison.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995

     Revenues

     Revenues increased by $8.9 million or 9% to $103.1 million for the six
months ended June 30, 1996.  This increase is a result of higher volumes offset
by lower electrochemical unit ("ECU") prices.  The average ECU price in the
first six months of 1996 decreased 9% from the first six months of 1995 because
of a decrease in prices for caustic soda.

     Cost of Sales

     Cost of sales increased by $9.8 million or 15% to $73.7 million for the
six months ended June 30, 1996.  This increase is attributable to higher
volumes sold and higher raw material prices, particularly electrolytic power
which increased due to substantially higher natural gas prices, a major
component of power costs at one plant.  The combination of lower ECU prices and
higher raw material costs resulted in a reduction of the gross profit margin in
the 1996 period to 28.5% from 32.1%.

     Selling, General and Administrative Expense

     Selling, general and administrative expense increased by $1.9 million or
15% to $14.3 million during the 1996 period primarily due to increased goodwill
amortization resulting from the Acquisition and additional accrued compensation
pursuant to the Company's incentive compensation program.

     Interest Expense, Net

     Interest expense during the first six months of 1996 increased to $8.8
million from $5.3 million for the 1995 period due to indebtedness incurred as a
result of the Acquisition.

     Other Income, Net

     Other income, net was $1.1 million lower in the first six months of 1996
due to insurance proceeds recognized in the 1995 period.

     Income Before Income Taxes and Extraordinary Item

     As a result of the above, net income before taxes and extraordinary
item decreased $7.2 million to $6.6 million for the six months ended June
30, 1996 from $13.8 million for the six months ended June 30, 1995.

     Provision for Income Taxes

     Provision for income taxes was $3.7 million in 1996 as compared to $5.7
million in 1995 due to lower pre-tax income.  Taxable income is higher than
book income due to the non-deductibility of amortization of the excess cost
over the fair value of the net assets acquired.  A provision is recorded on the
income statement; however, federal income taxes payable are reduced due to the
utilization of the net operating loss carryforward.

     Extraordinary Expense

     An extraordinary expense of $3.4 million net of an income tax benefit of
$2.1 million recorded during the first six months of 1995 was due to costs
incurred, and previously capitalized costs written off, pertaining to debt
refinanced by the Predecessor Company in 1995 prior to the Acquisition.

RESULTS OF OPERATIONS--(CONTINUED)

THREE MONTHS ENDED JUNE 30, 1996 COMPARED TO THREE MONTHS ENDED JUNE 30, 1995

     Revenues

     Revenues increased by $7.8 million or 17% to $54.2 million for the three
months ended June 30, 1996.  This increase is a result of higher volumes offset
by lower electrochemical unit ("ECU") prices.  The average ECU price for the
three months ended June 30, 1996 decreased 10.3% from the three months ended
June 30, 1995 as chlorine prices remained constant while caustic soda prices
reflected decreases of 16.1%.

     Cost of Sales

     Cost of sales increased by $5.6 million or 17% to $39.0 million for the
three months ended June 30, 1996.  This increase, which is primarily
attributable to higher volumes sold and higher raw material prices,
particularly electrolytic power which increased due to substantially higher
natural gas prices, would have been $1.7 million higher if purchase accounting
had not resulted in a step-up in inventory value in that amount in 1995.
Because of that factor, the gross profit margin in the 1996 period of 28.1% was
approximately the same as 1995.  In addition, one of the Company's subsidaries
substantially improved its margin on lower sales, which contributed to the
favorable comparison.

     Selling, General and Administrative Expense

     Selling, general and administrative expense increased by $0.3 million or
4% to $7.5 million during the 1996 period primarily due to additional accrued
compensation pursuant to the Company's incentive compensation program.

     Interest Expense, Net

     Interest expense during the first three months of 1996 increased to $4.5
million from $3.9 million for the 1995 period due to indebtedness incurred as a
result of the Acquisition and the purchase of KWT.

     Other Income, Net

     Other income, net was $0.4 million lower in the first three months of 1996
due to insurance proceeds recognized in the 1995 period.

     Income Before Income Taxes and Extraordinary Item

     As a result of the above, net income before taxes and extraordinary
item increased $0.9 million to $3.3 million for the three months ended June
30, 1996 from $2.4 million for the three months ended June 30, 1995.

     Provision for Income Taxes

     Provision for income taxes was $1.9 million in 1996 as compared to $1.4
million in 1995 due to higher pre-tax income.  Taxable income is higher than
book income due to the non-deductibility of amortization of the excess cost
over the fair value of the net assets acquired.  A provision is recorded on the
income statement; however, federal income taxes payable are reduced due to the
utilization of the net operating loss carryforward.

LIQUIDITY AND CAPITAL RESOURCES

     The Company incurred substantial indebtedness in connection with the
Acquisition and the transaction with Kemira.  As of June 30, 1996, the Company
had outstanding indebtedness of approximately $143.0 million.  The Company
incurred $8.0 million of term debt concurrently with the acquisition of KWT,
with principal payments due at various times beginning March 31, 2000 and with
a final payment due December 31, 2002.

     The Company has an available Credit Facility which provides a $30 million
revolving line of credit, subject to borrowing base limitations that relate to
the level of accounts receivable and inventory.  As of June 30, 1996, the
Company had $2.9 million of letters of credit outstanding and had, subject to
certain restrictions (including borrowing base limitations), the ability to
draw up to $23.3 million of additional secured indebtedness under the Credit
Facility.

     The Company believes that cash flow from current and anticipated future
levels of operations and, to a lesser extent, the availability under the Credit
Facility, will be adequate to make the required payments of principal and
interest on outstanding indebtedness, as well as to fund its foreseeable
capital expenditures and working capital requirements. Annualized cash interest
of $19.8 million will be payable on the Company's long-term debt. To the extent
that the Company were to draw upon the commitments under the Credit Facility
due to adverse business conditions or to finance acquisitions or for other
corporate purposes, the Company's aggregate interest expense would be
increased.

     The Company anticipates that capital expenditures for 1996, excluding
acquisitions, will be approximately $16.0 million, including approximately $3.4
million for environmental compliance matters. The Company believes that
forecasted capital expenditures will permit it to maintain its facilities on a
basis competitive within the industry through improved efficiency and
throughput and continuation of high operating rates.

     The Company's belief that it will generate sufficient cash flow for its
requirements is based, among other things, on the assumptions that: (i) the
Company's cash flow will be positive as a result of the continuing
profitability of its business; (ii) the Company will invest in working capital
in accordance with prior practices; (iii) the Company will not incur any
material capital expenditures in excess of its business plan.

     Net Cash Provided by Operating Activities.   The Company generated $8.0
million in cash from operating activities from profitability, depreciation and
the utilization of a net operating loss carryforward offset by an increase in
working capital (excluding the effect of the purchase of KWT).  Working capital
increased because of the seasonal increase in accounts receivable.

     Net Cash Used in Investing Activities.   Cash used in investing activities
for the first six months of 1996 was $10.5 million, primarily due to the
purchase of KWT by the Company and the purchase of property plant and
equipment.

     Net Cash Provided by (Used in) Financing Activities.   There was no cash
provided by or used in financing activities in the first six months of 1996.
The Company obtained approximately $150.0 million in cash through borrowings
and the issuance of common stock from the Acquisition offset by the payment of
dividends on Preferred Stock during the first six months of 1995.

                          PART II - OTHER INFORMATION


Item 5.  Other Information.

   On July 31, 1996, All-Pure Chemical Co. ("All-Pure"), an indirect
wholly-owned subsidiary of Pioneer Americas Acquisition Corp.,  acquired T.C.
Products, Inc. ("T.C. Products") through the acquisition of its parent, T.C.
Holdings, Inc., from trusts formed by Albert J. Clerc and Richard L. Belveal.
Consideration for the acquisition consisted of net cash payments of $5,458,835
and All-Pure subordinated notes with an aggregate principal amount of
$4,500,000.  The Company's existing cash balances were used to fund the cash
portion of the purchase price.

   T.C. Products is the sole operating asset of T.C. Holdings, Inc.  Following
the acquisition T.C. Products continues to manufacture and package bleach and
related products at its plant in Tacoma, Washington.  Mr. Clerc has agreed to
continue as an officer of T.C. Products for a period of up to one year
following the acquisition; both he and Mr.  Belveal have also agreed not to
compete with T.C. Products for a period of three years following the
acquisition.

   It is impractical to provide the required financial statements of T.C.
Products, the business acquired, at this time.  Such financial statements,
consisting of audited financial statements for the fiscal year ended September
30, 1995, unaudited financial statements for the nine-month period ended June
30, 1996, and pro forma unaudited financial statements, will be filed as soon
as practicable, but not later than October 11, 1996, under cover of an
amendment on Form 8 to this Form 10-Q.

         or subtenant of the Company or T.C.  Products either is or has been
         required to obtain any Governmental Approval to construct, occupy,
         operate, use or conduct any activity currently ongoing on any of the
         Assets and Properties of the Company or T.C. Products by reason of any
         Environmental Law; and

                 (i)      none of the Assets and Properties presently or
         heretofore owned or controlled by the Company or T.C. Products is
         currently on or has ever been on, or is or has ever been proposed for
         listing on or investigation under, any federal or state "superfund" or
         "super lien" list, including CERCLA.

                 Section 3.26.  Public Utility Holding Company.  Neither the
Company nor T.C. Products is a "holding company," a "subsidiary company" of a
"holding company," an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company" or a "public utility," as such terms are
defined in the Public Utility Holding Company Act of 1935 and the rules and
regulations thereunder.

                 Section 3.27.  Acquisition Transactions.  Except for the
letter of intent dated April 19, 1996 between certain of the Sellers and

broker, finder or financial advisor has acted for Sellers or the Company or
T.C. Products in connection with this Agreement or any of the Closing Documents

fee or other commission in respect thereof based in any way on any Contract
with Sellers, the Company or T.C. Products.

                 Section 3.30.  Disclosure.  The schedules, documents,
exhibits, reports, certificates and other written statements and information
furnished by or on behalf of Sellers, the Company or  T.C. Products to
Purchaser do not contain any material misstatement of fact or, to the knowledge
of Sellers or the Company, omit to state a material fact necessary in order to
make the statements contained therein, in light of the circumstances under
which they were made, not misleading.  Sellers have not withheld any fact known
to them or the Company which has or is reasonably likely to have a Material
Adverse Effect with respect to the Company or T.C. Products.

                 Section 3.31.  Representations Relating to Subordinated Notes.
(a) Each Seller understands that the Subordinated Notes have not been
registered under the Securities Act nor qualified under any state securities
laws, and that such securities are being offered and sold pursuant to an
exemption from such registration and qualification based in part upon the
representations of the Sellers contained herein.

                 (b)      Each Seller has such knowledge and experience in
financial and business matters that it is capable of evaluating the merits and
risks of the investment contemplated by this Agreement.  Each Trust is able to
bear the economic risk of its investment in Purchaser, including, but not
limited to, a complete loss of its investment.

                 (c)       Each Seller understands: (i) that the Trust must
bear the economic risk of this investment indefinitely unless the Subordinated
Notes are registered pursuant to the Securities Act or, in the opinion of
counsel reasonably satisfactory to Purchaser, an exemption from such
registration is available, and unless the disposition of such securities is
qualified under applicable state securities laws or, in the opinion of counsel
reasonably satisfactory to Purchaser, an exemption from such qualification is
available; and (ii) that Purchaser has no obligation or present intention of so
registering or qualifying any of the Subordinated Notes.  Each Trust further
understands that there is no assurance that any exemption from the Securities
Act will be available, or, if available, that such exemption will allow the
Trust to sell, assign, pledge, hypothecate, encumber or otherwise transfer or
dispose of (each, a "Transfer") any subordinated Note then held by the Trust in
the amounts or at the times the Trust might propose.

                 (d)      Each Trust is acquiring the Subordinated Notes solely
for its own account for investment and not with a view toward the resale,
Transfer, or distribution thereof, nor with any present intention of
distributing the Subordinated Notes.  Except as provided in this Agreement, the
Trust has not granted to another Person any right with respect to or interest
in the Subordinated





                                      -19-
<PAGE>   24
Notes, nor has the Trust agreed to give any Person any such interest or right
in the future (excepting any rights or interests which may exist by virtue of
community property laws).


                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF PURCHASER

                 Subject to all of the terms, conditions and provisions of this
Agreement, Purchaser hereby represents and warrants to Sellers, as of the date
hereof and as of the Closing Date, as follows:

                 Section 4.01.  Organization and Qualification.  Purchaser is a
corporation, duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of incorporation.  Purchaser has all requisite power
and authority, corporate or otherwise, to own, lease and operate its Assets and
Properties and to carry on its business as now being conducted.  Purchaser is
duly qualified to do business and is in good standing in each jurisdiction in
which its Assets or Properties or the nature of the business conducted by it
makes such qualification necessary and where the failure to so qualify would
have a Material Adverse Effect with respect to Purchaser and its subsidiaries.

                 Section 4.02.  Authority.  Purchaser has all requisite power
and authority, corporate or otherwise, to execute and deliver this Agreement
and the Closing Documents to which it is a party and to consummate the
transactions contemplated hereby and thereby.  The execution and delivery by
Purchaser of this Agreement and the Closing Documents to which it is a party
and the consummation of the transactions contemplated hereby and thereby have
been duly and validly authorized by the Board of Directors of Purchaser and no
other corporate proceedings or approvals on the part of Purchaser are necessary
to authorize this Agreement or the Closing Documents or to consummate the
transactions contemplated hereby or thereby.  Purchaser has duly and validly
executed and delivered this Agreement and will, on or prior to the Closing
Date, execute and deliver each of the Closing Documents to which it is a party
and, assuming the due authorization, execution and delivery of this Agreement
and such Closing Documents by the other parties hereto and thereto, this
Agreement constitutes, and when executed and delivered each of such Closing
Documents will constitute, the legal, valid and binding obligation of
Purchaser, enforceable against Purchaser in accordance with its terms, except
as such enforcement may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar Laws affecting creditors' rights
generally and general equitable principles.

                 Section 4.03.  No Conflict.  The execution and delivery by
Purchaser of this Agreement and the Closing Documents to which it is a party
and the consummation of the transactions contemplated hereby and thereby do not
and shall not, by the lapse of time, the giving of notice or otherwise: (a)
constitute a violation of any Law; (b) constitute a breach or violation of any
provision contained in its charter documents; (c) constitute a breach of any
provision contained





                                      -20-
<PAGE>   25
in, or a default under, any Governmental Approval, any writ, injunction, order,
judgment or decree of any Governmental Authority or any Contract to which
Purchaser is a party or by which Purchaser or its Assets and Properties is
bound or affected; or (d) except as otherwise contemplated by this Agreement
and the Closing Documents, result in or require the creation of any Lien upon
any of the Assets and Properties of Purchaser.

                 Section 4.04.  Consents and Approvals.  Except as set forth in
Schedule 4.04, no Governmental Approvals and no notifications, filings or
registrations to or with any Governmental Authority or any other Person is or
will be necessary for the valid execution and delivery by Purchaser of this
Agreement and the Closing Documents to which it is a party, or the consummation
of the transactions contemplated hereby or thereby, or the enforceability
hereof or thereof, other than those which have been obtained or made and are in
full force and effect.

                 Section 4.05.  Litigation.  There are no Claims pending or, to
the knowledge of Purchaser, threatened before or by any Governmental Authority
or any other Person, and Purchaser has no knowledge of the basis for any Claim,
which either alone or in the aggregate, seeks to restrain or enjoin the
execution and delivery of this Agreement or any of the Closing Documents or the
consummation of any of the transactions contemplated hereby or thereby.  There
are no judgments or outstanding orders, injunctions, decrees, stipulations or
awards (whether rendered by a Governmental Authority or by an arbitrator)
against Purchaser which prohibit or restrict, or could reasonably be expected
to result in any delay of, the consummation of the transactions contemplated by
this Agreement or any of the Closing Documents.

                 Section 4.06.  Exchange Act Filings. The Annual Report on Form
10-K of Pioneer for its fiscal year ended December 31, 1995 (and the
information incorporated by reference therein) (the "Form 10-K") contained all
information required to be contained therein and otherwise complied in all
material respects with the Exchange Act and the rules and regulations
thereunder.

                 Section 4.07.  Financial Statements.  Purchaser has delivered
to Sellers the audited consolidated balance sheet of Pioneer as of the close of
its fiscal year ended December 31, 1995 and statements of income and cash flows
for the fiscal year then ended and the preceding fiscal year, accompanied by a
report of independent auditors, which financial statements (including the notes
thereto) are collectively referred to as "Purchaser Financial Statements".  The
Purchaser Financial Statements fairly present the consolidated financial
position and results of operations of Pioneer as of the dates indicated therein
and results of operations for the fiscal periods indicated therein, in
accordance with GAAP which, except as may otherwise be noted in the footnotes
thereto, have been applied on a basis consistent with prior periods.  The
Purchaser Financial Statements reflect or provide for Claims against, and Debts
and Liabilities of, Pioneer and its consolidated group, absolute, accrued,
contingent or otherwise, as at the dates thereof in accordance with GAAP.

                 Section 4.08.  No Adverse Change.  Since December 31, 1995
there has been no change in the business, financial condition, results of
operations or prospects (in the case of





                                      -21-
<PAGE>   26
prospects, not taking into account general economic conditions or general
industry developments) which has had a Material Adverse Effect on Pioneer and
its consolidated group.

                 Section 4.09.  Issuance of Subordinated Notes.  The issuance
to the Trusts of the Subordinated Notes referred to in Section 2.04 has been or
will, prior to Closing, be duly and validly authorized by all necessary
corporate action of Purchaser.

                 Section 4.10.  Acquisition of the Stock for Investment.
Purchaser has such knowledge and experience in financial and business matters
that it is capable of evaluating the merits and risks of its purchase of the
Stock.  Purchaser confirms that Sellers have made available to Purchaser the
opportunity to ask questions of the officers and management Employees of the
Company and T.C. Products and to acquire additional information about the
business and financial condition of the Company and T.C. Products.  Purchaser
is acquiring the Stock for investment and not with a view to or for sale in
connection with any distribution thereof, or with any present intention of
distributing or selling the Stock (within the meaning of such terms under the
Securities Act).  Purchaser acknowledges that the Stock may not be sold,
transferred, offered for sale, pledged, hypothecated or otherwise disposed of
without registration under the Securities Act, except pursuant to an exemption
from such registration available under such Act, and without compliance with
state securities Laws, in each case, to the extent applicable.  Purchaser
understands that the Stock has not been and will not be registered under the
Securities Act or any state securities laws and is being offered and sold in
reliance upon federal and state exemptions for transactions not involving any
public offering.  Purchaser confirms that it is able to bear the economic risk
and lack of liquidity inherent in holding the Stock indefinitely.

                 Section 4.11.  Brokers, Finders and Financial Advisors.
Except for Schnitzius & Vaughan, whose fees and expenses shall be the sole
responsibility of Purchaser, no broker, finder or financial advisor has acted
for Purchaser in connection with this Agreement or any of the Closing Documents
or the transactions contemplated hereby or thereby, and no broker, finder or
financial advisor is entitled to any broker's, finder's or financial advisor's
fee or other commission in respect thereof based in any way on any Contract
with Purchaser.

                 Section 4.12.  Disclosure.  The representations and warranties
made by Purchaser in this Agreement and the statements made in any Closing
Documents, Exhibits or Schedules do not contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make any
such representation, warranty or statement, in light of the circumstances under
which it was made, not misleading.

                                   COVENANTS

                 Section 5.01.  Investigation of Business; Access to Properties
and Records.  (a) After the date hereof and prior to the Closing Date or the
earlier termination of this Agreement, Sellers shall and shall cause the
Company to afford to Purchaser and its accountants, counsel, financial advisors
and other representatives involved in the transactions contemplated by this
Agreement and the Closing Documents (the "Purchaser Representatives"), at
Purchaser's sole cost and expense, upon reasonable request during normal
business hours, full and complete access to the offices, Assets and Properties,
Books and Records and Contracts of the Company and T.C. Products; provided,
however, that such investigation shall be conducted in such a manner so as to
not cause any unreasonable disruption of or to the personnel and operations of
the Company or T.C. Products.  No investigation pursuant to this Section 5.01
shall affect any representations or warranties made in this Agreement or any of
the Closing Documents or the conditions to the obligations of the respective
parties to consummate the transactions contemplated hereby or thereby; provided
that any information obtained as a result of any such investigation or
diligence shall be subject to the covenant in Section 5.10(b).  Such
investigation and information obtained in connection therewith is subject to
the terms and conditions of that certain Confidentiality Agreement among
certain of the Sellers, the Company, Purchaser and another dated May 8, 1996
("Confidentiality Agreement"), and Purchaser shall hold and shall use
commercially reasonable efforts to cause the Purchaser Representatives to hold,
in strict confidence all non-public documents and information furnished to
Purchaser or the Purchaser Representatives in connection with the transactions
contemplated by this Agreement; provided, however, that: (i) Purchaser may
disclose any such information to the Purchaser Representatives; and (ii)
Purchaser and the Purchaser Representatives may disclose any such information
the failure of which to disclose would result in the violation of any Law or in
the imposition of any fine, penalty or charge by any Governmental Authority
that under authority of Law has required the disclosure or production of such
information by Purchaser or any of the Purchaser Representatives; provided
further, that in the event that Purchaser or a Purchaser Representative is
obligated to disclose any such information in order to avoid the violation of
any Law or the imposition of any fine, penalty or charge by any Governmental
Authority, it shall provide Sellers with such advance notice thereof as may be
reasonable under the circumstances in order to permit Sellers the opportunity
to intervene and seek appropriate relief for the protection of the
confidentiality of such information.  In the event of any conflict between the
terms and provisions hereof and of the Confidentiality Agreement, the terms and
provisions of this Agreement shall govern and control.

                 (b)      Purchaser agrees (i) to hold all of the material
Books and Records of the Company and T.C.  Products received by Purchaser from
Sellers on the Closing Date, and to not destroy or dispose of any thereof, for
a period of five years commencing on the Closing Date or such longer period as
may be required by Law, and (ii) following the Closing Date, to afford Sellers,
their accountants and counsel, at Sellers' sole cost and expense, upon
reasonable request, during normal





                                      -23-
<PAGE>   28
business hours, full and complete access to such Books and Records to the
extent that such access may be requested for any legitimate purpose; provided,
however, that such access shall be provided in such a manner so as to not cause
any unreasonable disruption of or to the personnel and operations of Purchaser,
the Company or T.C. Products.

                 (c)      In the event that this Agreement is terminated in
accordance with its terms, each party shall promptly destroy or redeliver to
the other all non-public written material provided pursuant to this Section
5.01 and shall not retain any copies, extracts or other reproductions in whole
or in part of such written material.  In such event, all documents, memoranda,
notes and other writings prepared by Purchaser based on the information in such
material shall also be destroyed (and Purchaser shall use commercially
reasonable efforts to cause the Purchaser Representatives to similarly destroy
their documents, memoranda, notes and other writings).

                 Section 5.02.  Closing Conditions; Obtaining Consents.
Subject to the terms and conditions herein provided, Sellers and Purchaser each
agree to use commercially reasonable efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all things necessary, proper or
advisable to consummate and make effective as promptly as practicable the
transactions contemplated by this Agreement and the Closing Documents and to
cooperate with the other in connection with the foregoing, including using
commercially reasonable efforts to: (a) obtain all waivers, consents and
approvals required to be obtained from other parties to Contracts of the
Company or T.C. Products; (b) obtain all Governmental Approvals required to be
obtained under any Law; (c) effect all necessary registrations and filings
including submissions of information requested by Governmental Authorities; and
(d) fulfill its respective conditions set forth in Article VI of this
Agreement.  Sellers and Purchaser do not believe that any notice is required to
be filed under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended.  Sellers and Purchaser further covenant and agree, with respect to any
threatened or pending preliminary or permanent injunction or other order,
decree or ruling or Law that would adversely affect the ability of Sellers, the
Company or Purchaser to execute and deliver this Agreement or any of the
Closing Documents or to consummate the transactions contemplated hereby or
thereby, to use commercially reasonable efforts to prevent the entry, enactment
or promulgation thereof, as the case may be, and to have any such injunction,
order or decree lifted or rescinded.

                 Section 5.03.  Further Assurances.  Sellers and Purchaser
agree that, from time to time, whether before, at or after the Closing Date,
each of them will take such other action as may be reasonably requested and
necessary or appropriate to carry out the purposes and intent of this Agreement
and the Closing Documents.  From time to time before, or at the request of
Purchaser, the Company or T.C. Products, after the Closing Date, Sellers, to
the extent they then may lawfully do so: (a) shall, and shall cause each of
their Affiliates to, take such actions and to execute, acknowledge and deliver
to the Company such Contracts, deeds, assignments, conveyances, transfers,
powers of attorney and assurances as may reasonably be necessary to effect or
evidence the transfer to the Company or T.C.  Products of any Assets and
Properties held by or in the name of, or which may appear in any public record
to be owned by, any such Person and used or held for use primarily in
connection with the business of the Company or T.C. Products; and (b) shall
assist





                                      -24-
<PAGE>   29
the Company and T.C. Products in transferring to the Company or T.C. Products
all Governmental Approvals, if any, that are held by any such Person or any of
their respective predecessors and are necessary to the operation or maintenance
of the business of the Company or T.C. Products as currently conducted.

                 Section 5.04.  Conduct of Business.  Except as set forth in
Schedule 5.04 or as otherwise contemplated by this Agreement or the Closing
Documents, after the date hereof and prior to the Closing Date or earlier
termination of this Agreement, unless Purchaser shall otherwise agree in
writing, Sellers shall cause the Company and T.C. Products to:

                 (a)      not take or perform any act or refrain from taking or
         performing any act which, if taken or performed or failed to be taken
         or performed between the date of the most recent Annual Financial
         Statements and the date hereof, would have resulted in a breach of the
         representations and warranties of Sellers set forth in Section 3.09;
         provided, however, that with respect to Debt incurred for capital
         expenditures, in addition to the restrictions contained in Section
         3.09, any such Debt or commitment therefor shall not in the aggregate
         exceed $300,000;

                 (b)      not enter into any agreement, or extend an existing
         agreement, for the purchase of chlorine or caustic soda that will
         survive after the Closing Date;

                 (c)      not sell (other than sales of inventory in the
         ordinary course of business), pledge, lease, license or otherwise
         transfer any of their Assets or Properties or, except as contemplated
         by this Agreement, make any payments or distributions to Sellers or
         any of their Affiliates;

                 (d)      in the case of T.C. Products, not make any payments
         or distributions of Assets or Properties to the Company or Sellers
         except for products purchased or services performed and at prices
         charged in the ordinary course of business and consistent with past
         practices;

                 (e)      confer on a regular and frequent basis with one or
         more representatives of Purchaser to report operational matters of
         materiality and the general status of ongoing operations; and

                 (f)      not enter into any Contract to (i) take or perform
         any act which Sellers are required to cause the Company to not take or
         perform pursuant to this Section 5.04 or (ii) refrain from taking or
         performing any act which Sellers are required to cause the Company to
         take or perform pursuant to this Section 5.04.

Nothing contained in this Agreement shall give to Purchaser, directly or
indirectly, rights to control or direct the Company's operations prior to the
Closing Date.  Prior to the Closing Date, the Company shall exercise,
consistent with the terms and conditions of this Agreement, complete control
and supervision of its operations.

                 Section 5.05.  Public Announcements.  Except as required by
Law, without the prior written approval of the other party, neither Sellers nor
Purchaser will, and Sellers shall cause the Company to not, issue, or permit
any agent or Affiliate thereof to issue, any press release or otherwise make or
permit any agent or Affiliate thereof to make, any public statement or
announcement with respect to this Agreement, the Closing Documents or the
transactions contemplated hereby and thereby; provided, however, that to the
extent that, in the opinion of their respective counsels, any public statements
are required to be made by the Company or Purchaser pursuant to any Law, the
parties shall endeavor to consult with each other prior to issuing any such
press release or written public statement.

                 Section 5.06.  Acquisition Transactions.  After the date
hereof and prior to the Closing Date or the earlier termination of this
Agreement, Sellers shall not, and shall not permit the Company or T.C. Products
to, initiate, solicit, negotiate, encourage or facilitate any proposal or offer
to acquire all or any substantial part of the business or Assets and Properties
of the Company or T.C. Products, or any capital stock of the Company or T.C.
Products, whether by merger, purchase of Assets and Properties, tender offer or
otherwise, and whether for cash, securities or any other consideration or
combination thereof.  Sellers: (a) acknowledge and agree that a breach of any
of the covenants contained in this Section 5.06 will result in irreparable harm
to Purchaser which will not be compensable in money damages; and (b) agree that
such covenant shall be specifically enforceable and that specific performance
and injunctive relief shall be a remedy properly available to Purchaser for a
breach of such covenant.  Sellers further hereby agree jointly and severally,
to indemnify, defend and hold harmless Purchaser from and against any and all
Claims, Liabilities and Losses which may be imposed on, incurred by or asserted
against Purchaser, arising out of or resulting from any breach of the covenants
contained in this Section 5.06 or the inaccuracy of the representations set
forth in Section 3.27.

                 Section 5.07.  Tax Matters.  (a) Except as otherwise provided
in this Section 5.07, all Tax settlement agreements, arrangements, policies or
guidelines, formal or informal, express or implied, that may exist between the
Company, T.C. Products and Sellers and all obligations thereunder shall
terminate as of the Closing Date.

                 (b)      Sellers shall timely prepare and file (or cause to be
         so prepared and filed) all tax returns of the Company and T.C.
         Products due for all periods prior to the Effective Time, and shall
         provide copies of such returns a reasonable period of time prior to
         filing to Purchaser for review and comment; provided that such returns
         shall not be subject to Purchasers' approval.  All other returns shall
         be prepared and filed by Purchaser.  Sellers shall pay, or be
         responsible, for the Taxes arising out of or in connection with the

                 (c)      After the Closing Date, Purchaser and Sellers shall,
         and shall cause their respective Affiliates to, cooperate in the
         preparation of all Tax returns and reports and shall provide, or cause
         to be provided, to the requesting party any Books and Records
         pertaining to the Company or T.C. Products requested by such party in
         connection therewith, as well as access to, and the cooperation of,
         the accountants and auditors of Purchaser and Sellers.  Each party
         shall cooperate with the other in connection with any Tax
         investigation, audit or Claim.  Purchaser and Sellers shall, and shall
         cause their respective Affiliates to, preserve all Books and Records
         relating to any Liabilities for Taxes with respect to any taxable
         period until the later of the expiration of all applicable statutes of
         limitation (including any extensions thereof) or the conclusion of all
         Claims with respect to Taxes for such period.

                 (d)      After the Closing Date, Sellers shall indemnify,
         defend and hold harmless Purchaser, the Company and T.C. Products from
         and against any Pre-Closing Taxes.  Purchaser agrees to, after the
         Closing Date, indemnify, defend and hold harmless Sellers from and
         against any Taxes of the Company or T.C. Products other than
         Pre-Closing Taxes.  Sellers shall retain any refunds of Pre-Closing
         Taxes and Purchaser (or the Company or T.C. Products) shall retain any
         refunds received in respect of other Taxes.  In the event that
         Purchaser (or the Company or T.C. Products) receives any refund of
         Pre-Closing Taxes, such refunds will be paid to the Trusts in
         proportion to the ratio in which the Trusts held the shares of the
         Company at Closing.

                 (e)      In the event that Purchaser, the Company or T.C.
         Products receives notice, whether orally or in writing, of any pending
         or threatened Tax examinations, Claims settlements, proposed
         adjustments, assessments or reassessments or related matters with
         respect to Taxes that could affect Sellers, or if Sellers receive
         notice of such matters that could affect Purchaser, the Company or
         T.C. Products, the party receiving such notice shall notify in writing
         the potentially affected party within ten days thereof. The failure of
         any party to give such notice shall not impair that party's rights
         hereunder except to the extent that the other party demonstrates
         material detriment caused thereby.  Sellers shall have the right to
         control any audit or examination by any taxing authority, initiate any
         Claim for refund, file any amended return and contest, resolve and
         defend against any assessment, notice of deficiency or other
         adjustment or proposed adjustment relating or with respect to any
         Pre-Closing Taxes, and Purchaser, the Company and T.C. Products shall
         have a corresponding right with respect to other Taxes.

                 (f)      Sellers shall pay, or there shall be taken into
         account in determining the Purchase Price pursuant to Section 2.02,
         all Taxes arising out of or in connection with the transactions
         effected pursuant to this Agreement, including those arising from the
         sale by the Company of the Gig Harbor Property and the capital stock
         or Property and Assets of T-Chem  and Specialty Insurance, Inc.
         ("Specialty Insurance").  Sellers and Purchaser shall cooperate in
         filing all necessary documentation and returns with respect to such
         Taxes.

                 Section 5.08  Employee Matters.  As a material inducement and
part of the consideration to Sellers for consummation of the transactions
contemplated by this Agreement, Pioneer agrees to cause T.C. Products to
continue during the current fiscal year the incentive bonus plan currently in
place and, for the fiscal year to end September 30, 1996, to accrue and pay
bonuses in accordance with provisions of such plan, subject to any discretion
therein provided, in an amount not to exceed the aggregate amount of bonuses
paid for the fiscal year ended September 30, 1995, and to cause T.C. Products
to fulfill all obligations under the T.C. Products/Dial Corporation Asset
Purchase Agreement relating to the T.C. Products employees who were formerly
Dial Corporation employees.

Company or T.C. Products is destroyed by fire or other casualty, or is taken in
condemnation or under the right of eminent domain, or if proceedings for such
purposes shall be pending or threatened and: (a) any such destruction, taking
or proceeding or any threat thereof involves, or if more than one in the
aggregate involve, an amount in excess of $100,000, Purchaser shall have the
right, in its sole discretion, to terminate this Agreement by providing Sellers
written notice of its election to do so; or (b) any such destruction, taking or
proceeding or any threat thereof involves, or if more than one in the aggregate
involve, an amount less than or equal to $100,000,  or involves an amount in
excess thereof and Purchaser does not elect to terminate this Agreement
pursuant to Section 5.09(a), Purchaser shall purchase the Stock notwithstanding
any such destruction, taking or proceeding or threat thereof (without reduction
of the Purchase Price therefor) and Sellers shall, on the Closing Date: (i) pay
to Purchaser all sums paid to Sellers by third parties by reason of the
destruction or taking of such Assets and Properties; and (ii) assign, transfer
and set over unto Purchaser, without recourse against Sellers, all of the
rights, title and interests of Sellers in and to any unpaid awards or other
payments (including insurance proceeds not expended or committed to expenditure
by Sellers or the Company to repair or restore such destruction) from third
parties arising out of the destruction or taking of such Assets and Properties.
Prior to the Closing, none of Sellers, the Company or T.C.  Products shall
voluntarily compromise, settle or adjust any material amounts payable by reason
of any material destruction or taking of any of the Assets and Properties of
the Company or T.C. Products without first obtaining the written consent of
Purchaser.

                 Section 5.10.  Updating of Schedules; Certain Notifications.
(a) Sellers shall deliver to Purchaser: (i) an updated aged schedule of the
Receivables on the Closing Date, which schedule shall be prepared as of the
close of business on the Business Day immediately preceding the Closing Date;
and (ii) an update of all of the other Schedules to this Agreement not less
than two Business Days prior to the Closing Date.  From the date hereof until
the Closing Date, Sellers shall promptly notify Purchaser in writing of any
changes or additions to the Schedules or the occurrence of any event which to
Sellers knowledge has resulted in or could reasonably be expected to result in
a Material Adverse Effect with respect to the Company or T.C. Products.
Nothing contained herein shall be deemed in any way to constitute a waiver by
Purchaser of the conditions contained in Article VI.

                 (b)      Each of the Sellers and Purchaser shall promptly
notify the other in writing of the occurrence of any event which becomes known
to either Sellers or Purchaser and which will, or could reasonably be expected
to, result in the failure to satisfy any of the conditions to the obligations
of any party specified in Article VI.

                 Section 5.11.  Collection of Receivables; Guaranty.  Purchaser
will, or will cause the Company and T.C.  Products to, use commercially
reasonable efforts to collect the Receivables.  In the event that,
notwithstanding such efforts, any of the Receivables are not paid in full at
the expiration of the 120 day period commencing with the Closing Date,
Purchaser will deliver to Sellers a schedule setting forth the aggregate amount
of uncollected Receivables, specifying the account debtor of each such
Receivable and the outstanding amount due thereunder, together with invoices
and supporting documents, and Sellers shall pay Purchaser an amount equal to:
(a) the aggregate outstanding balance of such Receivables; minus (b) an amount
equal to the balance of the Reserves as of the Closing Date.  Upon receipt by
Purchaser of such amount from Sellers, Purchaser shall cause all right, title
and interest in and to the uncollected balances of such Receivables to be
assigned, transferred and delivered to Sellers, without recourse to Purchaser,
the Company or T.C. Products.  In the event that any such Receivables are
assigned, transferred and delivered to Sellers, Purchaser agrees to provide
Sellers with such reasonable assistance in the collection of such Receivables
as Sellers may reasonably request.  In the event that the Company or T.C.
Products makes any sales to or performs any services for any account debtor of
any of the Receivables after the Closing Date, any payments received by the
Company or T.C. Products from such account debtor shall be applied: (i) as
designated by such account debtor; or (ii) in the absence of any such
designation, to the oldest unpaid Receivable owed by such account debtor.  Each
of Purchaser and Sellers shall promptly pay to the other any amounts received
by him or it (or any Affiliates) on account of a Receivable (or any portion
thereof) which is, at such time, the property of the other or an Affiliate of
the other.

Company, and the Company shall accept, a noncompetition agreement

after the Closing Date, Pioneer agrees to cause any assignee Purchaser pursuant
to Section 9.06 which is issuer of the Subordinated Notes to be merged with and
into Western States and T.C. Products, with the intent and result that T.C.
Products shall be the surviving corporation and successor to the obligations to
the Trusts evidenced by the Subordinated Notes.  Failure timely to satisfy this
covenant shall be an event of default under the Subordinated Notes.

                                  TERMINATION

                 Section 7.01.  Termination.  This Agreement may be terminated
at any time prior to the Closing Date:

                 (a)      by the mutual written consent of Sellers and
         Purchaser;

                 (b)      by Sellers, on the one hand, or Purchaser, on the
         other hand, if (i) the non-terminating party or any of its Affiliates
         fails to satisfy any term, covenant, agreement or condition required
         to be satisfied by it on or before the Closing Date or (ii) there has
         been a breach of any representation, warranty, term, covenant or
         agreement made to or for the benefit of the terminating party or any
         of its Affiliates in this Agreement, which breach has not been cured
         as of the Closing Date;

                 (c)      by either Sellers or Purchaser if the Closing has not
         occurred on or prior to July 22, 1996; provided, however, that the
         right to terminate this Agreement shall not be available to any party
         whose failure, or the failure of any of its Affiliates, to fulfill an
         obligation under this Agreement has been the cause of or resulted in
         the failure of the Closing Date to occur on or before such date; or

                 (d)      by either Sellers or Purchaser upon the issuance of
         an injunction, stay or restraining order issued by any court of
         competent jurisdiction enjoining or preventing consummation of the
         purchase and sale of the Stock or the other transactions contemplated
         by this Agreement or any of the Closing Documents beyond July 22,
         1996, which injunction, stay or order has not been reversed, vacated
         or expired so as to permit the Closing Date to occur on or before July
         22, 1996.

                 Section 7.02.  Effect of Termination.  In order to elect to
terminate this Agreement pursuant to Section 7.01, written notice of such
election must be given by the terminating party to the other party and, upon
receipt of such notice by the non-terminating party, this Agreement shall
terminate and have no further effect, and the transactions contemplated hereby
shall be abandoned without any further action by either of the parties, except
that the provisions of Sections 3.27, 5.01(c), 5.06 (last sentence only), 7.02,
9.04, 9.13, 9.14 and 9.15 shall survive the termination of this Agreement;
provided, however, that if this Agreement is terminated by a party under
circumstances in which another party or any of its Affiliates has willfully or
in bad faith failed or refused to satisfy a covenant or condition to the
obligations of either party to consummate the transactions contemplated by this
Agreement (the "Defaulting Party"), the Defaulting Party shall be and remain





                                      -35-

liable for all Claims, Liabilities and Losses imposed on, incurred by or
asserted against the non-defaulting party, directly or indirectly, arising out
of or resulting from such failure.

                                  ARTICLE VIII

         Authority would likely result in any Administrative Proceeding; or

                 (f)      any Claim to fees or costs for alleged services by a
         broker, agent, finder or other Person claiming to act in a similar
         capacity at the request of Purchaser in connection with this Agreement
         or any of the Closing Documents;

provided, however, that Purchaser shall not be liable for any portion of any
Claims, Liabilities or Losses resulting from a material breach by any Seller of
any of his or its obligations under this Agreement or any of the Closing

         Hazardous Material was located on, about or within such Assets and
         Properties prior to or as of the Closing Date in violation of any
         Environmental Law or which is a basis for an Administrative Proceeding
         to the extent that such Administrative Proceeding relates to any
         period prior to the Closing Date (or that if reported to a

         such Administrative Proceeding);

                 (e)      any compliance, investigative, enforcement, cleanup,
         removal, containment, remedial, response, cost recovery, contribution,

         Products in connection with this Agreement or any of the Closing
         Documents;

provided, however, that Sellers shall not be liable for any portion of any
Claims, Liabilities or Losses resulting from a material breach by Purchaser of
its obligations under this Agreement or any of the Closing Documents or from a
Purchaser Indemnified Person's gross negligence, fraud or willful misconduct.

                 Section 8.03.  Limitations on Indemnification.  The
obligations of Purchaser and Sellers to indemnify any Person pursuant to this
Article VIII shall be subject to the following limitations:

                 (a)      except as provided in Sections 8.03(b) and 8.03(c),
         neither the Seller Indemnified Persons nor the Purchaser Indemnified
         Persons shall be entitled to receive any indemnification payments
         until the cumulative amount of all Claims, Liabilities and Losses for
         which indemnification is sought pursuant to this Article VIII shall
         exceed an amount equal to $75,000.  Once this threshold has been
         reached with respect to the Purchaser Indemnified Persons in the
         aggregate or the Seller Indemnified Persons in the aggregate, the
         Persons in such group shall be entitled to full payment for all
         Claims, Liabilities and Losses for which indemnification is provided
         pursuant to this Article VIII in excess of such





                                      -38-
<PAGE>   43
         threshold; provided that notice of such Claim shall have been given by
         such Seller Indemnified Person or Purchaser Indemnified Person, as the
         case may be, to Purchaser or Sellers within the two-year period after
         the Effective Time (or such longer period of time for notice of Claims
         as is provided in Section 8.06 hereof);

                 (b)      with respect solely to claims for indemnification
         pursuant to Section 8.02(d) or 8.02(e) or a breach of the
         representations and warranties in Section 3.25, the Purchaser
         Indemnified Persons shall not be entitled to receive any
         indemnification payments until the cumulative amount of all Claims,
         Liabilities and Losses for which indemnification is sought pursuant to
         such Sections exceed, an amount equal to $75,000 with respect to the
         Purchaser Indemnified Persons.  Once this threshold has been reached
         with respect to the Purchaser Indemnified Persons in the aggregate,
         the Persons in such group shall be entitled to full payment for all
         such Claims, Liabilities and Losses in excess of such threshold;
         provided however, the aggregate liability of Sellers for such Claims,
         Liabilities and Losses shall not exceed $1,000,000; provided further
         that notice of such Claim shall have been given by the Purchaser
         Indemnified Person to Sellers within the two-year period after the
         Effective Time as provided in Section 8.06(a) hereof; and

                 (c)      (i) the thresholds for recovery in Sections 8.03(a)
         and 8.03(b) are separate and relate solely to the claims covered by
         each such Section and shall not be combined, and (ii) notwithstanding
         Sections 8.03(a) and 8.03(b), there shall be no threshold or other
         limitations on claims for indemnification (i) pursuant to Sections
         5.07 and 5.11 or (ii) for a breach of the representations, warranties
         and covenants in Sections 3.27 and 5.06.

                 Section 8.04.  Indemnification Procedures.  The obligations
and Liabilities of any party to indemnify any other party pursuant to this
Article VIII shall be subject to the following terms and conditions:

                 (a)      Notice and Defense.  Within a reasonable period of
         time after a party or parties to be indemnified (whether one or more,
         the "Indemnified Party") receives actual notice of any Claim covered
         by Section 8.01 or 8.02, as the case may be, the Indemnified Party
         shall, if a Claim in respect thereof is to be made pursuant to Section
         8.01 or 8.02, as the case may be, notify the party from whom
         indemnification is sought (the "Indemnifying Party") in writing of
         such Claim; provided however, that the failure to so notify the
         Indemnifying Party shall not relieve the Indemnifying Party from any
         Liability which it may have to the Indemnified Party pursuant to
         Section 8.01 or 8.02, as the case may be, except to the extent of
         material detriment suffered by the Indemnifying Party as a result of
         such failure.  In the event that a Claim, Liability or Loss arises out
         of or results from matters with respect to third parties, the
         Indemnifying Party will undertake the defense thereof by
         representatives chosen by it which are reasonably acceptable to the
         Indemnified Party.  So long as the Indemnifying Party is defending any
         such Claim actively and in good faith, the Indemnified Party shall not
         settle such Claim.  Each of the Indemnifying Party and the Indemnified
         Party shall be entitled to consult with each other, to the extent it
         reasonably





                                      -39-
<PAGE>   44
         requests, in respect of the defense of such Claim and shall cooperate
         in the defense of any such Claim, including making its officers,
         directors, employees and Books and Records available for use in such
         Claim, and shall take those actions reasonably within its power which
         are reasonably necessary to preserve any legal defenses to such
         matters.

                 (b)      Failure to Defend.  If the Indemnifying Party, within
         a reasonable time after notice of any such Claim, fails to defend such
         Claim actively and in good faith, the Indemnified Party will (upon
         further notice) have the right to undertake the defense, compromise or
         settlement of such Claim or consent to the entry of a judgment with
         respect to such Claim, on behalf of and for the account and risk of
         the Indemnifying Party, and the Indemnifying Party shall thereafter
         have no right to challenge the Indemnified Party's defense,
         compromise, settlement or consent to judgment.

                 (c)      Indemnified Party's Rights.  Notwithstanding anything
         contained in this Article VIII to the contrary: (i) if there is a
         reasonable probability that a Claim may materially and adversely
         affect the Indemnified Party other than as a result of money damages
         or other money payments, the Indemnified Party shall have the right to
         defend, compromise or settle such Claim; and (ii) no consent order
         shall be entered into or Claim settled unless the Indemnified Party
         has given its prior written consent thereto, which consent shall not
         be unreasonably withheld or delayed; provided, however, that the
         Indemnified Party shall consent to any settlement, compromise or
         discharge of such Claim that the Indemnifying Party may recommend that
         by its terms fully releases the Indemnified Party from any further
         Claims with respect to the matters giving rise to such Claim.

                 Section 8.05.  Payment.  The Indemnifying Party shall promptly
pay the Indemnified Party any amount due under this Article VIII and reimburse
each Indemnified Party for all reasonable expenses (including reasonable
counsel fees) for which the Indemnified Party is entitled to be indemnified
hereunder as they are incurred by such Indemnified Party.  Upon judgment,
determination, settlement or compromise of any third party Claim, the
Indemnifying Party shall promptly pay on behalf of the Indemnified Party,
and/or to the Indemnified Party in reimbursement of any amount theretofore
required to be paid by it, the amount so determined by such judgment,
determination, settlement or compromise and all other Claims of the Indemnified
Party with respect thereto, unless in the case of a judgment or determination
an appeal is made from such judgment or determination; provided, however, that
if the Indemnifying Party desires to appeal from an adverse judgment or
determination, then the Indemnifying Party shall post and pay the cost of the
security or bond to stay execution of the judgment or determination pending
appeal.  Upon the payment in full by the Indemnifying Party of all of such
amounts, the Indemnifying Party shall succeed to the rights of the Indemnified
Party, to the extent such rights are not waived in settlement, against the
third party who made such third party Claim.

                 Section 8.06.  Other Indemnities; Survival of Representations,
Warranties and Covenants.  The indemnities provided in Sections 8.01 and 8.02
are in addition to, and not in lieu of, other indemnification obligations of
the parties contained in this Agreement.  Except as otherwise





                                      -40-
<PAGE>   45
provided herein, all representations, warranties, covenants and agreements made
by Sellers, the Company and Purchaser in this Agreement, the Closing Documents
or in any certificate or other instrument delivered by Sellers, the Company or
Purchaser under this Agreement or any of the Closing Documents shall survive
the execution and delivery of this Agreement and the Closing Documents,
regardless of any investigation made by or on behalf of any party; provided,
however, that:

                  (a)     the representations and warranties of Sellers, other
         than those contained in Sections 3.01 (first and fourth sentences
         only), 3.02, 3.03 and 3.04 (which shall survive indefinitely), and
         Section 3.21 (which shall survive as provided in subsection (b) of
         this Section 8.06), and the indemnification obligations of Sellers set
         forth in Section 8.02(d) and (e), shall terminate and have no further
         force or effect after the expiration of the two year period commencing
         on the Effective Time;

                 (b)      the representations and warranties of Sellers
         contained in Section 3.21 shall terminate and have no further force or
         effect upon the expiration of the statute of limitations period
         applicable thereto; and

                 (c)      the representations and warranties of Purchaser,
         other than those contained in Sections 4.01 (first sentence only) and
         4.02 and 4.10 (which shall survive indefinitely), shall terminate and
         have no further force or effect after the expiration of the two year
         period commencing on the Effective Time, and the indemnificiation
         obligations of Purchasers set forth in Section 8.01(d) and (e) shall
         survive indefinitely;

in each case unless notice of a Claim relating thereto shall be delivered by a
Purchaser Indemnified Person to Sellers, or a Seller Indemnified Person to
Purchaser, as the case may be, prior to the expiration of the specified period
(other than those whose period of survival is indefinite and as to which Notice
of Claims can be given at any time), in which case such representation,
warranty or indemnity shall survive following such period solely with respect
to such Claim until such Claim is resolved.  The right to indemnification
provided in this Article VIII shall be the exclusive remedy of any Purchaser
Indemnified Person or Seller Indemnified Person with respect to the inaccuracy
of any representation or the breach of any warranty made by Sellers or
Purchaser in this Agreement.

confirmation of receipt; and (D) in the case of a notice sent by overnight mail
or overnight courier service, the next Business Day after such notice is mailed
or delivered to such courier, in each case given or addressed as aforesaid.

                 Section 9.02.  Setoff.  Purchaser shall have the right to set
off and apply against any amounts owing to Purchaser by Sellers pursuant to the
terms of this Agreement or any of the Closing Documents any amounts owing
pursuant to the Subordinated Notes, subject to the following conditions:

                 (a)      no set-off against the Subordinated Notes shall be
         made in effecting payment under any item of this indemnity until the
         amount of any asserted Claim, Loss or Liability and the costs of
         defending the same are finally determined by agreement between
         Purchaser and Sellers or by final decision of a court or arbitrators
         as provided herein;

                 (b)      any amount set-off against the Subordinated Notes
         shall be applied to and reduce the payments next becoming due to the
         Trusts thereunder, with such next accruing installment payments being
         applied first to any amount Purchaser is entitled to set off
         hereunder;

                 (c)      following the giving of any notice of Claim, and if,
         but only if, (i) Sellers fail to acknowledge in writing to Purchaser
         and accept responsibility to indemnify and defend Purchaser with
         respect to such Claim as herein provided, and (ii) the maximum amount
         of Sellers liability under this Article VIII, as determined by the
         Board of Directors of Purchaser acting in good faith ("Maximum
         Amount"), is equal to or exceeds the remaining principal balance of
         the Subordinated Notes determined as of the date such notice of Claim
         is given ("Balance Due"), any installment payments of interest or
         principal which may thereafter come due pursuant to the Subordinated
         Notes may be paid into an escrow account, with a bank or other
         financial institution and pursuant to escrow instructions mutually
         agreed by the Trusts and Purchaser acting reasonably and in good
         faith, with funds so deposited to be held in escrow pending final
         determination of the full extent of Sellers liability hereunder, and
         Purchaser shall not be deemed in default with respect to any such
         payments or part thereof so deposited in escrow; provided, however,
         that Purchaser shall be entitled to deposit in escrow, equally from
         each Subordinated Note, only that portion of the payment due which
         does not exceed the Maximum Amount; provided further that once a
         Claim, Loss or other Liability is finally determined not to be payable
         by Sellers (in whole or part), any funds deposited in escrow to which
         the Trusts are entitled shall be paid over to the Trusts in accordance
         with their respective interests in the Stock;

                 (d)      the election of set-off shall not occur or be deemed
         to have occurred until and unless the set- off is actually consummated
         to effect payment of the Claim, Loss or Liability; and





                                      -43-
<PAGE>   48
                 (e)      Purchaser shall have and retain such rights as it may
         have against Sellers for any Loss, Liability or Claim not fully
         compensated for by exercise of the right of set-off.

For all purposes of this Agreement, the exercise by Purchaser of its right of
setoff as provided in this Section 9.02 shall not constitute a breach by
Purchaser of any of its covenants or agreements contained in this Agreement,
provided, however, the set-off provisions of this Section 9.02 shall constitute
all of Purchaser's rights of set-off as to any amount payable under the
Subordinated Notes and all other rights of set-off against the Subordinated
Notes, whether legal or equitable, are hereby expressly waived and relinquished
by Purchaser.  The contractual set-off rights in this Section 9.02 are in
addition to, and not in lieu of any and all other rights of set-off, whether
legal or equitable, which either Purchaser or any Seller may have, all of which
set-off rights are expressly reserved.

                 Section 9.03.  Benefit and Burden.  This Agreement shall inure
to the benefit of, and shall be binding upon, the parties hereto and their
successors and permitted assigns.

                 Section 9.04.  No Third Party Rights.  Nothing in this
Agreement shall be deemed to create any right in any creditor or other Person
not a party hereto (other than the Seller Indemnified Persons and the Purchaser
Indemnified Persons) and this Agreement shall not be construed in any respect
to be a Contract in whole or in part for the benefit of any third party (other
than the Seller Indemnified Persons and the Purchaser Indemnified Persons).

                 Section 9.05.  Amendments and Waiver.  No amendment,
modification, restatement or supplement of this Agreement shall be valid unless
the same is in writing and signed by the parties hereto.  No waiver of any
provision of this Agreement shall be valid unless in writing and signed by the
party against whom that waiver is sought to be enforced.  No failure or delay
on the part of any party hereto in exercising any right, power or privilege
hereunder and no course of dealing between or among any of the parties hereto
shall operate as a waiver of any right, power or privilege hereunder.  No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege hereunder.  No notice to or demand on any party in
any case shall entitle such party to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of any
party to any other or further action in any circumstances without notice or
demand.

                 Section 9.06.  Assignments.  Except for Purchaser's right to
assign any of its rights, interests and obligations under this Agreement to an
Affiliate of Purchaser; and except for the right of a Trust to assign any of
its rights and interests under this Agreement in connection with a permitted
assignment of its interest in the Subordinated Notes, neither this Agreement
nor any right, interest or obligation hereunder may be assigned by any party
hereto and any attempt to do so shall be null and void; provided that no such
assignment by a Trust shall relieve such Trust of its obligations as a Seller
under this Agreement.





                                      -44-
<PAGE>   49
                 Section 9.07.  Counterparts.  This Agreement may be executed
in counterparts and by the different parties in separate counterparts, each of
which when so executed shall be deemed an original and all of which taken
together shall constitute one and the same agreement.

                 Section 9.08.  Captions and Headings.  The captions and
headings contained in this Agreement are inserted and included solely for
convenience and shall not be considered or given any effect in construing the
provisions hereof if any question of intent should arise.

                 Section 9.09.  Construction.  The parties acknowledge that
each of them has had the benefit of legal counsel of its own choice and has
been afforded an opportunity to review this Agreement with its legal counsel
and that this Agreement shall be construed as if jointly drafted by the parties
hereto.

                 Section 9.10.  Severability.  Should any clause, sentence,
paragraph, subsection, Section or Article of this Agreement be judicially
declared to be invalid, unenforceable or void, such decision will not have the
effect of invalidating or voiding the remainder of this Agreement, and the
parties agree that the part or parts of this Agreement so held to be invalid,
unenforceable or void will be deemed to have been stricken herefrom by the
parties, and the remainder will have the same force and effectiveness as if
such stricken part or parts had never been included herein.

                 Section 9.11.  Remedies.  The parties agree that the covenants
and obligations contained in this Agreement and the Closing Documents relate to
special, unique and extraordinary matters and that a violation of any of the
terms hereof or thereof would cause irreparable injury in an amount which would
be impossible to estimate or determine and for which any remedy at law would be
inadequate.  As such, the parties agree that if either party fails or refuses
to fulfill any of its obligations under this Agreement or any of the Closing
Documents or to make any payment or deliver any instrument required hereunder
or thereunder, then the other party shall have the remedy of specific
performance, which remedy shall be cumulative and nonexclusive and shall be in
addition to any other rights and remedies otherwise available under any other
Contract or at law or in equity and to which such party might be entitled.

                 Section 9.12.  Applicable Law.  THIS AGREEMENT AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF WASHINGTON, WITHOUT GIVING EFFECT TO
THE CONFLICT OF LAW PRINCIPLES THEREOF.

                 Section 9.13.  Submission to Jurisdiction.  Each of the
parties hereby: (a) irrevocably submits to the non-exclusive personal
jurisdiction of any Washington state or federal court sitting in Seattle,
Washington, over any Claim arising out of or relating to this Agreement or any
of the Closing Documents and irrevocably agrees that all such Claims may be
heard and determined in such Washington state or federal court; and (b)
irrevocably waives, to the fullest extent permitted by applicable Law, any
objection it may now or hereafter have to the laying of venue in any proceeding





                                      -45-
<PAGE>   50
brought in a Washington state or federal court sitting in Seattle, Washington,
and any claim that any such proceeding brought in a Washington state or federal
court sitting in Seattle, Washington, has been brought in an inconvenient
forum; provided, however, that nothing in this Section 9.13 is intended to
waive the right of either of the parties to remove any such action or
proceeding commenced in any such Washington state court to an appropriate
Washington federal court to the extent the basis for such removal exists under
applicable Law.  Each of the parties hereby irrevocably agrees that service of
copies of the summons and complaint and any other process which may be served
in any such action or proceeding may be made by mailing, by certified mail, a
copy of such process to such party at its address for notices specified herein.
As an alternative method of service, each of the parties also irrevocably
consents to the service of any and all process in any such action or proceeding
by the mailing by certified mail of copies of such process to it at its address
for notices specified herein.  Each of the parties agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
Law.  Nothing in this Section 9.13 shall affect the right of either of the
parties to serve legal process in any other manner permitted by Law or affect
the right of either of the parties to bring any action or proceeding in the
courts of any other jurisdictions, domestic or foreign.

                 Section 9.14.  Arbitration.  Upon the demand of either party,
whether made before or after the institution of any judicial proceeding, any
Dispute shall be resolved by binding arbitration in accordance with the terms
of the arbitration provisions contained on Annex "B" attached hereto and
incorporated herein for all purposes.  Either party to this Agreement may, by
summary proceedings (e.g., a plea in abatement or motion to stay further
proceedings), bring any action in court to compel arbitration of any Dispute.
Either party who fails or refuses to submit to binding arbitration following a
lawful demand by the other party shall bear all costs and expenses incurred by
such other party in compelling arbitration of any Dispute.

                 Section 9.15.  Expenses; Prevailing Party Costs.  Each of
Sellers and Purchaser shall pay its own expenses incident to this Agreement and
the Closing Documents and the transactions contemplated hereby and thereby,
including all legal and accounting fees and disbursements, and Sellers shall be
solely liable for any and all expenses of the Company which are incident to
this Agreement and the Closing Documents and the transactions contemplated
hereby and thereby (other than customary general, administrative and overhead
expenses incurred in the ordinary course of business).  Notwithstanding
anything contained herein or therein to the contrary, if any party commences an
action against another party to enforce any of the terms, covenants, conditions
or provisions of this Agreement or any of the Closing Documents, or because of
a breach by a party of its obligations under this Agreement or any of the
Closing Documents, the prevailing party in any such action shall be entitled to
recover its Losses, including reasonable attorneys' fees, incurred in
connection with the prosecution or defense of such action, from the losing
party.

                 Section 9.16.    Entire Agreement.  This Agreement, the
Western States Letter and the Closing Documents set forth all of the promises,

                             ARBITRATION PROVISIONS

(a)      All Disputes between the parties submitted to arbitration shall be
         resolved by binding arbitration administered by the American
         Arbitration Association (the "AAA") in accordance with, and in the
         following order of priority: (i) the terms of these arbitration
         provisions; (ii) the Commercial Arbitration Rules of the AAA; (iii)
         the Federal Arbitration Act (Title 9 of the United States Code); and
         (iv) to the extent the foregoing are inapplicable, unenforceable or
         invalid, the Laws of the State of Washington.  The validity and
         enforceability of these arbitration provisions shall be determined in
         accordance with this same order of priority.  In the event of any
         inconsistency between these arbitration provisions and such rules and
         statutes, these arbitration provisions shall control.  Judgment upon
         any award rendered hereunder shall be entered in any court having
         jurisdiction.

(b)      All statutes of limitation applicable to any Dispute shall apply to
         any proceeding in accordance with these arbitration provisions.

(c)      Arbitrators are empowered to resolve Disputes by summary rulings
         substantially similar to summary judgments and motions to dismiss.
         Arbitrators shall resolve all Disputes in accordance with the
         applicable substantive Law.  Any arbitrator selected shall be required
         to be experienced and knowledgeable in the substantive Laws applicable
         to the subject matter of the Dispute.  With respect to a Dispute in
         which the claims or amounts in controversy do not exceed $250,000, a
         single arbitrator shall be chosen and shall resolve the Dispute.  In
         such case, the arbitrator shall be required (unless all parties to the
         proceeding shall otherwise agree in writing) to make specific, written
         findings of fact, and shall have authority to render an award up to
         but not to exceed $250,000, including all amounts properly payable and
         costs, fees and expenses.  A Dispute involving claims or amounts in
         controversy exceeding $250,000, shall be decided by a majority vote of
         a panel of three arbitrators (an "Arbitration Panel"), the
         determination of any two of the three arbitrators constituting the
         determination of the Arbitration Panel; provided, however, that all
         three arbitrators on the Arbitration Panel must actively participate
         in all hearings and deliberations.  Arbitrators, including any
         Arbitration Panel, may grant any remedy or relief deemed just and
         equitable and within the scope of these arbitration provisions and may
         also grant such ancillary relief as is necessary to make effective any
         award.  Arbitration Panels shall be required (unless all parties to
         the proceeding shall otherwise agree in writing) to make specific,
         written findings of fact and conclusions of law.  The determination of
         an arbitrator or Arbitration Panel shall be binding on all parties and
         shall not be subject to review or appeal.





                                      B-i

(d)      To the maximum extent practicable, the AAA, the arbitrator (or the
         Arbitration Panel, as appropriate) and the parties shall take any
         action necessary to require that an arbitration proceeding hereunder
         shall be concluded within 180 days of the filing of the Dispute with
         the AAA.  Unless the parties shall agree otherwise, arbitration
         proceedings hereunder shall be conducted in San Francisco, California.
         Arbitrators shall be empowered to impose sanctions, permit or order
         depositions and discovery and to take such other actions as they deem
         necessary to the same extent a judge could pursuant to the Federal
         Rules of Civil Procedure and applicable law.  With respect to any
         Dispute, each party agrees that all discovery activities shall be
         expressly limited to matters directly relevant to the Dispute and any
         arbitrator, Arbitration Panel and the AAA shall be required to fully
         enforce this requirement.  The provisions of these arbitration
         provisions shall survive any termination, amendment or expiration of
         this Agreement, unless the parties otherwise expressly agree in
         writing.  To the extent permitted by applicable Law, arbitrators,
         including any Arbitration Panel, shall have the power to award
         recovery of all costs and fees (including attorneys' fees,
         administrative fees and arbitrators' fees) to the prevailing party or,
         if no clear prevailing party, as the arbitrator (or Arbitration Panel,
         if applicable) shall deem just and equitable.  Each party agrees to
         keep all Disputes and arbitration proceedings strictly confidential,
         except for disclosures of information required by applicable Law.

                                    PREAMBLE

                 WHEREAS, Pioneer Companies, Inc. (the "Company") maintains the
Pioneer Companies, Inc. Incentive Cash Bonus Plan (the "Cash Bonus Plan") to
help the Company attract and retain exceptional employees and to provide a
direct incentive to such employees to improve the profitability of the Company;
and

                 WHEREAS, the Company desires to more closely align the
interests of its key executives who are participants in the Cash Bonus Plan
with those of the Company's stockholders by providing that part of any annual
cash bonus that they may earn under the Cash Bonus Plan will be automatically
deferred under this Plan as a Phantom Stock Award, which on its subsequent
vesting will be paid in shares of Company Stock;

                 NOW, THEREFORE, subject to the approval of this Plan by the
stockholders of the Company, the Company hereby establishes the Plan as set
forth herein, effective as of January 1, 1996.

                                   SECTION 1

         Participant, on a form provided by the Management Committee and filed
         with the Company's Human Resources Department, to receive benefits
         from the Plan in the event of his death.  A Participant may change his
         beneficiary designation at any time.  If no designated Beneficiary
         survives the Participant, the Beneficiary shall be the Participant's
         surviving spouse or, if none, his estate.

                 1.2      Board means the Board of Directors of the Company.

         Committee of the Board.

                 1.6      Employers means the Company and its subsidiaries.

         date, the closing sale price per share of the Company Stock on such
         date in the principal market in which the Company Stock is traded, as
         reported in The Wall Street Journal, or, if no Company Stock was
         traded on such date, on the next preceding day on which Company Stock
         was so traded; provided, however, with respect to the initial
         crediting of an automatic deferral of a bonus amount in Phantom Stock,
         Fair Market Value shall mean the average of the closing sales price
         per share of the Company Stock on the last business day of each
         calendar month for the calendar year immediately preceding the date
         such Phantom Stock is credited to the Participant's Phantom Stock
         Account.

                 1.8      Incentive Award means the amount of a Participant's
         cash bonus award under the Cash Bonus Plan for a year as determined
         pursuant to Section 6.1, but before the automatic 50% "deferral" with
         respect to such award pursuant to this Plan.

                 1.9      Management Committee means the committee appointed
         pursuant to Section 2.1 to administer the Plan.

                 1.10     Participant means a key executive of the Employers

                 1.11     Permanent Disability means the Compensation Committee
         has found, upon the basis of medical evidence satisfactory to it, that
         a Participant has become totally disabled, whether due to physical or
         mental condition, so as to be prevented from continuing to engage
         further in his regular full-time duties with his Employer and that
         such disability is reasonably expected to be permanent or long-term.

                 1.12     Phantom Stock means a phantom or notional share of
         Company Stock.  A Participant shall not possess any rights of a

                 1.15     Specified Deferral Date means a date after the
         vesting date for a Phantom Stock grant on which a Phantom Stock grant
         is to be paid or commence, as designated by a Participant in a
         voluntary deferral election.

                 1.16     Termination means a Participant's termination of
         employment with the Employers for any reason.


                                   SECTION 2

                                 ADMINISTRATION

                 2.1      Committee.  The Plan shall be administered by the
Compensation Committee; however, the Compensation Committee may delegate its
ministerial duties under the Plan to a committee consisting of such employees
of the Employers as the President of the Company shall designate (the
"Management Committee").  The Compensation Committee shall have the authority
and power to interpret the Plan, prescribe, amend and rescind rules relating to
its administration, select the key executives who shall be Participants,
determine a Participant's (or Beneficiary's) right to a payment and the amount
of such payment, and to take all other actions necessary or desirable for the
administration of the Plan.  All actions and decisions of the Compensation
Committee shall be final and binding upon all Participants and Beneficiaries.

                                   SECTION 3

                                  PARTICIPANTS

                 3.1      Participants. The Compensation Committee shall
determine and designate the key executives of the Employers who are eligible to
participate under the Plan.  Participation is intended to be limited to those
key executives who, because of their positions, have significant responsibility
for the management, direction and success of the Company, a subsidiary or a
significant business unit.  The Compensation Committee may provide for
participation by the designation of key executives by position or individually
and any participation designation may be a continuing designation until
rescinded or may be limited to a specified bonus year, in the Compensation
Committee's sole discretion.

                                   SECTION 4

                     INCENTIVE AWARDS PERFORMANCE CRITERIA

                 4.1      Incentive Awards.  If the EBITDA target established
for the Company's  Shared Earnings Program for a bonus year is met or exceeded,
the Compensation Committee shall establish the Incentive Awards for the
Participants under the Cash Bonus Plan for such year.  The amount of the
Incentive Awards may be based upon the recommendation of the Company's
President and/or on such other factors as the Compensation Committee deems
appropriate.

                 4.2      Performance Criteria.  Individual Incentive Awards
for Participants will be based upon the Participant's performance for the year
and may be measured against objective and/or subjective standards established
in advance for the Participant by the Compensation Committee.  There may be one
or more performance objectives, different weights may be accorded different
objectives, and different objectives may be established for different
Participants.  In evaluating the Participants, the Compensation Committee may
consider the corporate objectives of the Company for the year and the
individual's responsibilities and accomplishments, and may consider
recommendations of the President of the Company and such other factors as it
deems appropriate.


                                   SECTION 5

                        LIMITATIONS ON INDIVIDUAL AWARDS

                 5.1      Incentive Award Limits.  In no event may the
Incentive Award for any Participant for a bonus year exceed the Maximum Annual
Percentage for such Participant as set forth on Attachment A.

                 5.2      Adjustments to Awards.  The Compensation Committee,
in its discretion, may grant all or such portion of an Incentive Award for a
year as it deems advisable to a Participant (or his Beneficiary in the case of
his death) who either becomes a Participant or is promoted after the beginning
of the bonus year, or whose employment is terminated during the year because of
his retirement, death, Permanent Disability or the sale or other disposition of
an Employer or a business unit.

                                   SECTION 6

                              PHANTOM STOCK AWARDS

                 6.1      Phantom Stock Award.  Each Participant shall have 50%
of his Incentive Award otherwise payable to him in cash under the Cash Bonus
Plan for a year automatically deferred in shares of Phantom Stock under this
Plan, and receive an additional "matching" number of shares of Phantom Stock
credited to his Phantom Stock Account as provided below.  The number of shares
of Phantom Stock automatically credited to a Participant's Phantom Stock
Account for any year with respect to which the Participant is entitled to
receive an Incentive Award under the Cash Bonus Plan shall be equal to (1) 100%
of the Participant's Incentive Award for that bonus year, determined prior to
any automatic deferral with respect to such award under this Section 6.1,
divided by (2) the Fair Market Value of the Company Stock for that bonus year.
The remaining 50% of the Participant's Incentive Award for the year shall be
paid to the Participant pursuant to the terms of the Cash Bonus Plan.

                 6.2      Vesting in Phantom Stock. The shares of Phantom Stock
automatically credited to a Participant, and any phantom dividends subsequently
credited thereon, shall not vest (i.e., shall remain forfeitable) until the
second January 1 following the date on which the related Incentive Award was
approved by the Compensation Committee; provided, however, if the Participant's
employment with the Employers is terminated due to his death, Disability,
retirement with the consent of the Compensation Committee, or by an Employer
other than for Cause (as defined in the Company's 1995 Stock Incentive Plan),
all shares of Phantom Stock then credited to the Participant's Phantom Stock
Accounts shall be immediately vested in full.  If a Participant terminates
employment with the Employers for any reason other than as provided above, all
nonvested shares of Phantom Stock then credited to the Participant's Phantom
Stock Accounts shall be immediately forfeited without payment.

         Unless the Participant  has made a deferral election pursuant to
Section 6.3, the shares of Phantom Stock credited to the Participant's Phantom
Stock Account shall be automatically paid to the Participant in whole shares of
Company Stock, with cash for any fractional share, as soon as reasonably
practicable following the date such Phantom Stock becomes vested.

                 6.3      Voluntary Deferrals.  Prior to the beginning of any
year with respect to which the Compensation Committee has authorized elective
deferrals of Phantom Stock awards by Participants, each Participant may elect
to have the payment of all or a designated portion of his Phantom Stock to be
credited for that year, if any, deferred until the date of his Termination or,
if permitted by the Compensation Committee, to a Specified Deferral Date that
is prior to his Termination, but in all cases after the normal January 1
vesting date for such Phantom Stock.  The deferral election must be irrevocable
and must be made on a form prescribed by the Management Committee, which shall
govern the amount deferred, and the manner and timing of its payment.  A





                                      -5-
<PAGE>   8
Participant's deferral election shall apply only to the Incentive Award for
that election year.  If a Participant has not made a deferral election, the
Phantom Stock award for that year shall be payable pursuant to Section 6.2.

                 6.4      Accounts.  Each year the Company shall establish a
Phantom Stock Account for each Participant who has received an Incentive Award
that year to reflect the shares of Phantom Stock automatically deferred with
respect to such award; provided, however, all Phantom Stock Accounts for a
Participant that are to be paid at the same time may be combined into a single
Phantom Stock Account.

                 6.5      Investment of Accounts.  Each Phantom Stock Account
shall be credited with whole and fractional shares of Phantom Stock as of the
date of the automatic deferral of the 50% portion of the Incentive Award for
such year and with phantom (notional) dividends with respect to the credited
Phantom Stock, which shall be credited as being reinvested in additional shares
of Phantom Stock based on the Fair Market Value of the Company Stock on the
applicable date.

                 6.6      Payment of Deferred Accounts.  Upon a Participant's
Termination or earlier Specified Deferral Date, if applicable, the Company
shall pay to such Participant (or to his or her Beneficiary in case of the
Participant's death) the vested balance then credited to his or her Phantom
Stock Account(s) as follows:

                          (a)     in a lump sum payment; or

                          (b)     in five substantially equal annual
                 installments ("equal" shall be determined with reference to
                 the number of shares credited to such Phantom Stock Account);

whichever form of payment has been elected by the Participant.  Payments of
deferred Phantom Stock Accounts shall commence or be made as soon as reasonably
practicable following the earlier of the Participant's date of Termination or
Specified Deferral Date.  Payments shall be made in whole shares of Company
Stock, with any fractional share paid in cash.

                 6.7      Acceleration of Payments.  Notwithstanding any
Participant deferral election to the contrary, the Compensation Committee, in
its sole discretion, may accelerate the payment of all or part of the unpaid
balance of any Phantom Stock Account on or following the Participant's
Termination.

                 6.8      Change in Control.  Notwithstanding anything in the
Plan to the contrary, on the date of a Change in Control of the Company (as
defined in the Company's 1995 Stock Incentive Plan), all Phantom Stock Accounts
shall be fully vested and, regardless of any deferral elections, paid in cash
based on the CIC Fair Market Value of the Company Stock; provided, however,
with respect to any Participant who is subject to Section 16 of the Securities
Exchange Act of 1934, any shares of Phantom Stock that have been credited to
his Phantom Stock Account for less than six





                                      -6-
<PAGE>   9
months as of the date of the Change in Control shall continue to remain
credited to his Phantom Stock Account until the expiration of six months and
one day from the date such shares were credited to the Phantom Stock Account,
at which time such shares of Phantom Stock shall be paid to the Participant in
cash based on the CIC Fair Market Value of the Company Stock.  For purposes of
this Section 6.8, the CIC Fair Market Value of the Company Stock shall be the
greater of (i) the fixed or formula price for the acquisition of shares of
Company Stock specified in the agreement effecting the Change in Control of the
Company, if applicable, and (ii) the highest reported price per share of the
Company Stock during the sixty-day period ending on the date of the Change in
Control.


                                   SECTION 7

                               GENERAL PROVISIONS

                 7.1      Unfunded Obligations.  The amounts to be paid to
Participants pursuant to this Plan are unfunded obligations of the Company.
The Company is not required to segregate any monies from its general funds, to
create any trusts, or to make any special deposits with respect to these
obligations.  Title to and beneficial ownership of any investments, including
trust investments, which the Company may make to fulfill these obligations
shall at all times remain in the Company.  Any investments and the creation or
maintenance of any trust or notional accounts shall not create or constitute a
trust or a fiduciary relationship between the Compensation Committee or the
Company and a Participant, or otherwise create any vested or beneficial
interest in any Participant or his Beneficiary or his creditors in any assets
of the Company whatsoever.  The Participants (and Beneficiaries) shall have no
claim against the Company for any changes in the value of any Accounts and
shall be general unsecured creditors of the Company with respect to any payment
due under this Plan.

                 7.2      Incapacity of Participant or Beneficiary.  If the
Compensation Committee finds that any Participant or Beneficiary to whom a
payment is payable under the Plan is unable to care for his affairs because of
illness or accident or is under a legal disability, any payment due (unless a
prior claim therefore shall have been made by a duly appointed legal
representative) at the discretion of the Compensation Committee, may be paid to
the spouse, child, parent or brother or sister of such Participant or
Beneficiary or to any person whom the Compensation Committee has determined has
incurred expense for such Participant or Beneficiary.  Any such payment shall
be a complete discharge of the obligations of the Company under the provisions
of the Plan.

                 7.3      Nonassignment.  The right of a Participant or
Beneficiary to the payment of any amounts under the Plan may not be assigned,
transferred, pledged or encumbered in any manner nor shall such right or other
interests be subject to attachment, garnishment, execution or other legal
process.





                                      -7-
<PAGE>   10
                 7.4      No Right to Continued Employment.  Nothing in the
Plan shall be construed to confer upon any Participant any right to continued
employment with the Employers, nor interfere in any way with the right of an
Employer to terminate the employment of such Participant at any time without
assigning any reason therefor.

                 7.5      Withholding of Taxes.  To the extent that the Company
is required to withhold any taxes in connection with any payment or award made
to a Participant or any other person under this Plan, it will be a condition to
the receipt of such payment or award that the Participant or such other person
make arrangements satisfactory to the Company for the payment of such taxes.

                 7.6      Termination and Amendment.  The Board may from time
to time amend, suspend or terminate the Plan, in whole or in part, at any time;
provided that any amendment that would materially increase the benefits
accruing to Participants under the Plan, increase the aggregate number of
shares of Company Stock which may be issued under the Plan or materially modify
the requirements as to eligibility for participation in the Plan, shall be
subject to the approval of Company's stockholders, except that any such
increase or modification that may result from adjustments authorized by Section
7.7 does not require such approval.  No amendment, suspension or termination of
the Plan may impair the right of a Participant or his Beneficiary to receive
the benefit accredited hereunder prior to the effective date of such amendment,
suspension or termination.

                 7.7      Company Stock Shares Available Under the Plan.
Subject to adjustments as provided below, the maximum number of shares of
Company Stock which may be issued with respect to shares of Phantom Stock
credited under the Plan shall be 500,000 shares.  Such shares of Company Stock
may be shares of original issuance or treasury shares or a combination of the
foregoing.  Any shares of Company Stock which are issuable with respect to
shares of Phantom Stock that are forfeited will again be available for issuance
under this Plan.  In the event that the number of shares of Company Stock
available under this Plan is insufficient on any applicable date, then
notwithstanding anything in the Plan to the contrary, all Participants who
would otherwise be entitled to have shares of Phantom Stock credited to a
Phantom Stock Account on such date shall instead share ratably in the number of
shares of Phantom Stock then available for crediting under this Plan, and
thereafter all Incentive Awards (or remaining portions) shall be paid in cash
pursuant to the terms of the Cash Bonus Plan and thereafter all notional
dividends and other amounts credited on shares of Phantom Stock shall be
credited in cash and paid in cash.  In the event of a change in the
capitalization of the Company due to a stock split, stock dividend,
recapitalization, merger, consolidation, combination, or similar event, the
aggregate number of shares subject to the Plan and the shares of Phantom Stock
then credited shall be adjusted accordingly by the Compensation Committee to
reflect such change.

                 7.8      Applicable Law.  Except to the extent preempted by
any applicable federal law, the Plan shall be construed and governed in
accordance with the laws of the State of  Delaware.
