                                     PART I

     Unless the context otherwise requires, (i) the term "Pioneer" refers to
Pioneer Americas Acquisition Corp., (ii) the terms "Pioneer Americas" and
"Predecessor Company" refer to Pioneer Americas, Inc. and its subsidiaries,
(iii) the term "Company" means Pioneer and its subsidiaries and (iv) the term
"PCI" refers to Pioneer Companies, Inc., the parent company of Pioneer.

ITEM 1.  BUSINESS.

THE ACQUISITION

     On April 20, 1995 (the "Closing Date"), 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 of Pioneer Americas, Inc. (the "Sellers"), Pioneer
acquired all of such stock and interests (the "Acquisition") for a purchase
price equal to the sum of approximately (i) $102 million, paid in cash, (ii)
$11.5 million aggregate principal amount of subordinated promissory notes of PCI
(the "Seller Notes") and (iii) certain amounts payable after the closing based
upon earnings or proceeds attributable to certain of the Company's direct and
indirect real estate holdings which are not necessary for the Company's
chlor-alkali business. In addition, as further consideration for the
Acquisition, Pioneer paid approximately $51.7 million to retire all outstanding
indebtedness of Pioneer Americas and $5 million to redeem the outstanding
preferred stock of Pioneer Americas, Inc.

     In connection with the consummation of the Acquisition, (i) Pioneer issued
$135 million in principal amount of 13 3/8% Senior Notes due 2005 (the "Senior
Notes"), (ii) PCI issued the Seller Notes in exchange for certain of the
outstanding shares of Pioneer Americas, Inc., which PCI contributed to Pioneer,
(iii) PCI issued to Interlaken Investment Partners, L.P., a Delaware limited
partnership (the "Interlaken Partnership") Class A Common Stock of PCI for an
aggregate purchase price of $15 million (the "Interlaken Partnership Purchase"),
the proceeds of which were contributed to Pioneer, (iv) PCI issued to Richard C.
Kellogg, Jr. and Frans G.J. Speets, directors and executive officers of Pioneer
Americas, and to certain other employees of Pioneer Americas, Class A Common
Stock of PCI for an aggregate purchase price of $6 million (the "Management
Purchase"), the proceeds of which were contributed to Pioneer, and (v) Pioneer
Americas entered into a new bank revolving credit facility (the "Bank Credit
Facility") with Bank of America Illinois, providing for borrowings of up to $30
million. The net proceeds of the sale of the Senior Notes, the Interlaken
Partnership Purchase, the Management Purchase and a borrowing under the Bank
Credit Facility were used to pay the cash portion of the purchase price of the
Acquisition, to retire the outstanding Pioneer Americas indebtedness and to
redeem the outstanding preferred stock of Pioneer Americas, Inc.

GENERAL

     Pioneer is a wholly-owned subsidiary of PCI. PCI is a publicly-traded
company, which prior to the Acquisition was actively seeking acquisitions and
had no operations. As of December 31, 1996, PCI had a net operating loss
carryforward ("NOL") which PCI believes is approximately $35.6 million and is
available to offset future taxable income. As of December 31, 1996, the
Interlaken Partnership beneficially owned approximately 35.6% of the voting
power of PCI, William R. Berkley (who may be deemed to beneficially own all
shares of PCI common stock held by the Interlaken Partnership) beneficially
owned approximately 61.0% of the voting power of PCI.

     Following its formation in 1988, the Predecessor Company acquired two
chlor-alkali plants previously owned and operated by Stauffer Chlor Alkali
Company, Inc., and it subsequently acquired several businesses engaged in
municipal, industrial and commercial water treatment. During 1996 the Company
conducted its primary business through its operating subsidiaries: Pioneer Chlor
Alkali Company, Inc. ("PCAC"), All-Pure Chemical Co. ("All-Pure") (including
T.C. Products, Inc. following its acquisition in July 1996), and Imperial West.
In 1996, PCAC accounted for 71% of the Company's total revenues, and All-Pure
and Imperial West accounted for 28% and 1%, respectively, of the Company's total
revenues, net of intercompany eliminations. In February 1996 PCI formed a new
company, Kemwater North America Company ("Kemwater"), to continue the business
activities previously conducted by its subsidiary, Imperial West Chemical Co.
("Imperial West"), and to operate the business acquired through the acquisition
of KWT, Inc. ("KWT") from a subsidiary of Kemira Oy of Finland ("Kemira"). Fifty
percent of the common stock of Kemwater is held by a subsidiary of Pioneer and
fifty percent of the common stock of Kemwater is owned by a subsidiary of PCI. A
subsidiary of Pioneer also owns all of the outstanding shares of Kemwater's
preferred stock. Fifty percent of the results of Kemwater's operations are
included in the Company's equity in net loss of unconsolidated subsidiary.

     PCAC. PCAC owns and operates two chlor-alkali production facilities,
located in St. Gabriel, Louisiana and Henderson, Nevada. These facilities, which
are the largest operated by the Company, produce chlorine and caustic soda for
sale in the merchant markets and for use as raw materials by PCAC, All-Pure and
Kemwater in the manufacture of downstream products. The Henderson facility also
produces hydrochloric acid. PCAC also has an indirect 15% equity interest in
Saguaro Power Company L.P. ("Saguaro Power"), which owns and operates a
90-megawatt cogeneration facility located on approximately six acres of the
Henderson property.

     Chlorine and caustic soda are co-products, concurrently produced in a ratio
of 1 to 1.1, respectively, through electrolysis of salt water. An
electrochemical unit ("ECU") consists of one ton of chlorine and 1.1 tons of
caustic soda.

     On December 11, 1996, the Company announced that it had initiated
discussions with Occidental Chemical Corporation ("OxyChem") regarding the
proposed acquisition by the Company of OxyChem's Tacoma, Washington chlor-alkali
facility (the "Tacoma Facility"). If agreement with OxyChem on the terms of the
transaction can be reached, the Company expects that the securing of required
financing and completion of the transaction could occur during the first half of
1997. The Tacoma facility would be PCAC's largest plant.

     All-Pure. All-Pure manufactures bleach, repackages chlorine and
hydrochloric acid and distributes these products along with caustic soda and
related products to municipalities, swimming pool supply distributors and
selected commercial and retail markets in the western United States. Because
bleach contains a high percentage of water, freight costs and logistics are an
important competitive factor. All-Pure's production plants and distribution
facilities are strategically located in or near most of the largest population
centers of the West Coast. All-Pure purchases all of its chlorine and caustic
soda and a substantial portion of its hydrochloric acid from PCAC. In July 1996,
All-Pure acquired T.C. Products, Inc. ("T.C. Products"), which is engaged in the
manufacture and marketing of bleach and related products from its plant in
Tacoma, Washington.

(1)  The pro forma results of operations, which combine the Company's operating
     results for the year ended December 31, 1995 and the Predecessor Company's
     operating results from January 1, 1995 through April 20, 1995, are provided
     for comparative purposes. The Predecessor Company's operating results
     exclude approximately $1.0 million of transaction costs related to the
     Acquisition. The Company believes that this provides a meaningful basis for
     comparison. The Company and the Predecessor Company have different asset
     bases and the effects on operating results of these differences are
     discussed in the comparison which follows.
(2)  To continue the business activities previously conducted by Imperial West
     Kemwater was formed in connection with the acquisition of KWT in February
     1996 and, accordingly, the results of operations for the year ended
     December 31, 1996 include the results of operations include operations of
     Imperial West only for the month of January 1996. Fifty percent of
     Kemwater's results of operations are included as equity in net loss of
     unconsolidated subsidiary since the acquisition.
(3)  T.C. Products was acquired in July 1996 and, accordingly, the results of 
     operations for the year ended December 31, 1996 includes the results of 
     operations since the acquisition date. T.C. Products generated third party
     sales during such period of $5.1 million.
(4)  An extraordinary item of $3.4 million net of an income tax benefit of $2.1
     million recorded during the 1995 period was due to costs incurred and
     previously capitalized costs written off, pertaining to debt refinanced by
     the Predecessor Company prior to the Acquisition.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO PRO FORMA YEAR ENDED DECEMBER 31, 1995

Revenues

      Revenues decreased by $17.4 million or 9% to $183.3 million for 1996
compared to 1995. The business activities of Imperial West were transferred in
February 1996 to Kemwater which caused a decrease in sales of approximately
$19.8 million. The Company owns 50% of the common stock of Kemwater. The
decrease in sales was partially offset by the acquisition of T.C. Products
during 1996, which accounted for a $5.1 million increase in revenue. Revenues
for the Company's chlor-alkali products during 1996 remained relatively
unchanged from 1995 as an approximate 9% increase in caustic soda sales volumes
was offset by a 7% decrease in ECU netback.

Cost of Sales

     Cost of sales decreased by approximately $8.8 million from $135.5 million
in 1995 to $126.7 in 1996. The decrease was a result of the aforementioned 
transfer of Imperial West operations to Kemwater, partially offset by a $3.1 
million increase due to the acquisition of T.C. Products.

Selling, General and Administrative Expenses

     Selling, general and administrative expenses decreased approximately $3.4
million to $23.5 million in 1996 due primarily to the aforementioned transfer 
of Imperial West operations to Kemwater during 1996.

Equity in Net Loss of Unconsolidated Subsidiaries

     Equity in net loss of unconsolidated subsidiaries, resulting from the KWT
acquisition in 1996, arises from a 50% ownership interest in Kemwater.

Interest Expense, Net

     Interest expense increased by $2.7 million or 19% to $17.3 million for
1996. This increase was a result of debt incurred in connection with the
Acquisition as well as debt incurred in financing the T.C. Products acquisition.

Provision for Income Taxes

     Provision for income taxes for 1996 was $6.7 million, with an effective tax
rate of 45%, compared to $11.0 million, with an effective tax rate of 44%, for
1995. The decrease in the provision was primarily a result of the decrease in
the Company's income before income tax and extraordinary item to $14.8 million
for 1996 from $25.2 million in 1995. Taxable income is higher than book income
due to the non-deductibility of amortization of the excess cost over the fair
value of net assets acquired. A provision is recorded on the income statement
based on taxable income; however, federal income taxes payable are reduced and
paid-in capital is increased due to the utilization of the net operating loss
carryforward.

Net Income

     Due to the factors described above, net income for the year ended December
31, 1996 was $8.1 million, compared to $10.8 million for 1995.

     In accordance with the terms of an Exchange and Registration Rights
Agreement (the "Exchange Agreement") which Pioneer entered into at the time of
the Acquisition, on January 23, 1996, Pioneer exchanged $135.0 million of its
13 3/8% First Mortgage Notes due 2005 (the "Mortgage Notes") for all of the
outstanding Senior Notes. The Mortgage Notes and obligations outstanding under
the Bank Credit Facility are secured by first mortgages on PCAC's St. Gabriel

      From time to time, the Company is involved in litigation relating to
claims arising out of its operations in the normal course of its business. The

                          INDEPENDENT AUDITORS' REPORT



To the Board of Directors of

changes in stockholders' equity, and cash flows for the year ended December 31,

These financial statements and schedule are the responsibility of the Company's

the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by

We believe that our audit provides a reasonable basis for our opinion.

       In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of

                       PIONEER AMERICAS ACQUISITION CORP.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  ORGANIZATION AND BASIS OF PRESENTATION

     Pioneer Americas Acquisition Corp. ("Pioneer") is a Delaware corporation
formed on March 6, 1995 ("Inception"). Pioneer is 100% owned by Pioneer 
Companies, Inc. ("PCI").

     On April 20, 1995, Pioneer acquired Pioneer Americas, Inc. ("Pioneer
Americas" or the "Predecessor Company") for approximately $177 million (the
"Acquisition"). Pioneer Americas manufactured chlorine, caustic soda and related
products used in a variety of applications including water treatment, plastics,
detergents, and agricultural chemicals. Consideration for the Acquisition
included cash, assumption of certain liabilities and repayment of debt of the
Predecessor Company, redemption of preferred stock of the Predecessor Company
and fees and expenses related to the Acquisition. In connection with the
Acquisition, PCI sold common stock, issued long-term debt and entered into a new
bank revolving credit facility. The Acquisition was accounted for as a purchase;
accordingly, the purchase price was allocated to the assets acquired and
liabilities assumed based upon their fair market value and the operations of the
Predecessor Company were included in the consolidated financial statements from
the date acquired. The Acquisition resulted in $112 million of excess cost over
the fair value of the net assets acquired, which is being amortized on a
straight line basis over 25 years.

      In February 1996, Pioneer acquired an interest in Kemwater North America
Company ("Kemwater") for $0.3 million of cash and a contribution of the assets
and liabilities of its subsidiary Imperial West Chemical Co. ("Imperial West").
Kemwater was formed to conduct the operations of Imperial West and KWT, Inc.
(acquired by PCI in February 1996). Kemwater, which manufactures and supplies
iron chlorides that are used to remove solids from water streams and to control
hydrogen sulfide emissions by the potable and waste water markets, is owned 50%
by Pioneer and 50% by PCI. Since it does not own a controlling interest in
Kemwater, Pioneer accounts for Kemwater using the equity method. In the 1996
consolidated financial statements, Pioneer's investment in Kemwater is presented
as "Investment in and advances to unconsolidated subsidiary" and its equity in
the loss of Kemwater is shown as "Equity in net loss of unconsolidated
subsidiary." In the 1995 consolidated financial statements of Pioneer, Imperial
West is consolidated and includes the following: total assets of $25.7 million,
total revenues of $23.7 million and net loss of $0.6 million. Had the
acquisition been made as of January 1, 1996 and 1995, it would not have had a
significant impact on the consolidated financial statements for 1996 and 1995. 
The acquisition did not have a material impact on Pioneer's financial 
statements, and therefore pro forma information is not presented.

     Pioneer acquired T.C. Products in July 1996 for $10.0 million. T.C.
Products manufactures bleach and related products. The acquisitions was
accounted for as a purchase; accordingly, the purchase price was allocated to
the assets acquired and liabilities assumed based upon their fair market value
and the operations for the acquired company was included in the consolidated
financial statements from the date acquired. The acquisition resulted in $7.0
million of excess cost over the fair value of the net assets acquired, which is
being amortized on a straight line basis over 25 years. Had the acquisition been
made as of January 1, 1996 and 1995, it would not have had a significant impact
upon the consolidated financial statements for 1996 and 1995. The acquisition
did not have a material impact on Pioneer's financial statements, and therefore
pro forma information is not presented.

     The consolidated financial statements include the accounts of Pioneer and
its consolidated subsidiaries (the "Company"). All significant intercompany
balances and transactions have been eliminated in consolidation. All dollar
amounts in tabulations in the notes to the consolidated financial statements are
stated in thousands of dollars unless otherwise indicated.

     Amounts presented in the notes to the consolidated financial statements for
the Predecessor Company are based upon its historical accounting basis for the
periods presented. Such amounts do not include effects of the purchase of the
Predecessor Company by Pioneer. Amounts presented in the notes to the
consolidated financial statements for the Predecessor Company for the period
from January 1, 1995 through April 20, 1995 and for the year ended December 31,
1994 are included under the captions "Predecessor Company, 1995" and
"Predecessor Company, 1994," respectively.


                                       17

     The Company operates in one industry segment and one geographic area.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH AND CASH EQUIVALENTS

      All highly liquid investments with a maturity of three months or less when
purchased are considered to be cash equivalents. Interest income is netted
against interest expense for the periods presented. The Company had interest
income for the year ended December 31, 1996 and the period from Inception
through December 31, 1995 of $0.7 million and $0.3 million, respectively. The
Predecessor Company had interest income of $0.1 million for each of the period
from January 1, 1995 through April 20, 1995 and the year ended December 31,

     Inventories are valued at the lower of cost or market. Finished goods and
work-in-process costs are calculated under the average cost method, which
includes appropriate elements of material, labor, and manufacturing overhead
costs, while the first-in, first-out method is utilized for raw materials,
supplies, and parts. The Company enters into agreements with other companies to
exchange chemical inventories in order to minimize working capital requirements
and to facilitate distribution logistics. Balances related to quantities due to
or payable by the Company are included in inventory. The results of operations
for the period from Inception through December 31, 1995 include the effects of
an increase of $1.7 million to cost of sales due to the step-up in value of
inventory in connection with the Acquisition.

PROPERTY, PLANT, AND EQUIPMENT

     Depreciation for financial reporting purposes is computed primarily under
the straight-line method over the estimated remaining useful lives of the
assets. Asset lives range from 5 years to 15 years with a predominant life of 10
years.

OTHER ASSETS

     Other assets include amounts for deferred financing costs which are being
amortized on a straight-line basis over the term of the related debt.
Amortization of such costs using the interest method would not result in
material differences in the amounts amortized during the periods presented.
Amortization expense for other assets for the year ended December 31, 1996 was
$1.3 million and for the period from Inception through December 31, 1995 was
approximately $1.1 million.

     Other assets of the Predecessor Company included amounts for organization
costs, deferred financing costs, non-compete agreements, permits, licenses, and
customer lists obtained in conjunction with the acquisitions of All-Pure
Chemical Co. ("All-Pure"), GPS Pool Supply, Inc. ("GPS") and Imperial West,
which were being amortized on a straight-line basis over their estimated useful
lives. The Predecessor Company's deferred financing costs were being amortized
on a straight-line basis over the term of the related debt. Amortization of such
costs using the interest method would not result in material differences in the
amounts amortized during the periods presented. Amortization expense for other
assets was approximately $0.8 million for the period from January 1, 1995
through April 20, 1995 and $1.7 million for the year ending December 31, 1994.

EXCESS COST OVER THE FAIR VALUE OF NET ASSETS ACQUIRED

     Excess cost over the fair value of net assets acquired of approximately
$115 million is amortized on a straight-line basis over periods of up to 25
years. The carrying value of excess cost over the fair value of net assets
acquired is reviewed annually and if this review indicates that such excess cost
will not be recoverable, as determined based on the estimated future
undiscounted cash flows of the entity acquired over the remaining amortization
period, the 


                                       18
<PAGE>   19

Company's carrying value of excess cost over the fair value of net assets
acquired will be reduced by the estimated shortfall of discounted cash
flows or the fair value of the related entity. No such reductions were made in
1996 or 1995. Amortization expense for excess cost over the fair value of net
assets acquired was approximately $4.7 million for the year ended December 31,
1996 and $3.3 million for the period from Inception through December 31, 1995.

      The Predecessor Company's excess cost over the fair value of net assets
acquired of approximately $12.8 million and is amortized on a straight-line
basis over 20 years. Amortization expense was approximately $0.2 million for the
period from January 1, 1995 through April 20, 1995 and $0.6 million for 1994.

ENVIRONMENTAL EXPENDITURES

     Remediation costs are accrued based on estimates of known environmental
remediation exposure. Such accruals are based upon management's best estimate of
the ultimate cost and are recorded even if significant uncertainties exist over
the ultimate cost of the remediation. Ongoing environmental compliance cost,
including maintenance and monitoring costs, are charged to operations as
incurred.

RETURNABLE DEPOSITS

      Customers are required to pay a security deposit on cylinders, tanks, and
containers. These deposits are refunded to the customer upon the termination of
service and return of cylinders, tanks, and containers.

INCOME TAXES

     The Company files a consolidated tax return with PCI. Pioneer has entered
into a tax sharing agreement with PCI whereby the Company will make tax sharing
payments to PCI with respect to federal cash income taxes reflecting the
consolidated cash tax liability of PCI. The tax sharing agreement has the effect
of presenting the income tax provision on a separate return basis. For financial
reporting purposes, deferred income taxes are determined utilizing an asset and
liability approach. This method gives consideration to the future tax
consequences associated with differences between the financial accounting basis
and tax basis of the assets and liabilities, and the ultimate realization of any
deferred tax asset resulting from such differences. State income taxes are
included in income taxes payable.

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

IMPAIRMENT OF LONG-LIVED ASSETS

During 1996, the Company adopted a new accounting standard for the impairment of
long-lived assets. This standard requires that certain assets be reviewed for
impairment whenever events or circumstances indicate that the carrying amount of
the assets may not be recovered. If it is determined that the asset's carrying
amount is not recoverable, the new accounting standard requires that the
carrying value be reduced to the fair value of the assets. Implementation of
this standard did not have a significant impact on the Company's 1996
consolidated financial statements.

     Certain amounts have been reclassified in prior years to conform to the
current year presentation. All reclassifications have been applied consistently

5.  INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED SUBSIDIARIES

KEMWATER

     Pioneer and PCI each own a 50% interest in Kemwater which was formed in
February 1996 to continue the business activities previously conducted by
Pioneer's subsidiary, Imperial West and to operate the business acquired by PCI
through the acquisition of KWT, Inc. At December 31, 1996, Pioneer's investment
in and advances to Kemwater aggregated $28.6 million investment in and advances
to Kemwater are primarily for purchase of product and to fund Kemwater's current
operations and capital requirements. Pioneer and PCI have funded, and intend to
continue funding in the foreseeable future, Kemwater's operations and capital
requirements; accordingly, Pioneer has reduced its investment at December 31,
1996 to a deficit of $0.3 million. Following is a summary of selected items from
Kemwater's balance sheet at December 31, 1996 and operations for the year ended
December 31, 1996 (in thousands):
        
Current assets                        $  13,004
Non-current assets                       32,224
Current liabilities                       7,294
Non-current liabilities                  40,498
Revenues                                 36,142
Gross profit                              1,865
Net loss                                 (5,214)


BII AND VVLC

     The Company, through its subsidiary Pioneer Chlor Alkali Company, Inc.
("PCAC"), owns approximately 32% of the common stock of Basic Investments, Inc.
("BII"), which owns and maintains the water and power distribution network
within the Henderson, Nevada industrial complex and which is a large landowner
in Clark County, Nevada. The remainder of the common stock of BII is owned by
other companies located in the industrial complex. Prior to the Acquisition, the
investment in BII was accounted for by the Predecessor Company under the equity
method after adjustment to reflect PCAC's basis.

     PCAC has an approximate 21% limited partnership interest in Victory Valley
Land Company ("VVLC"). The purpose of the business is to receive, hold and
develop the lands, water rights, and other assets contributed by the partners
for investment. A wholly owned subsidiary of BII, acting as general partner with
a 50% interest in VVLC, contributed all rights, title, and interest in and to
certain land to VVLC. PCAC assigned certain water rights to VVLC. Prior to the
Acquisition, the investment in VVLC was accounted for by the Predecessor Company
under the equity method.

     The Company's interests in BII and in VVLC (referred to as the Basic
Ownership) constitute assets that, pursuant to the Acquisition Agreement and a
related Contingent Payment Agreement, will be held for the 


                                       21
<PAGE>   22

economic benefit of the Sellers for a period of 20 years. Dividends and
distributions received by the Company on account of the Basic Ownership
(including amounts payable as a result of sales of land or other assets owned by
BII or VVLC) are deposited into a Contingent Payment Account and used to satisfy
certain obligations of the Sellers under environmental and other indemnities in
favor of the Company. After payment or provision for payment of such obligations
in accordance with the provisions of the Contingent Payment Agreement, amounts
received by the Company subsequent to April 20, 1995 on account of the Basic
Ownership will be remitted to the Sellers under the Contingent Payment Agreement
for such 20-year period. The Sellers also have certain rights during such period
with respect to determinations affecting the Basic Ownership, including the
right (subject to certain limited conditions) to direct the sales or disposition
of interests constituting the Basic Ownership and the right (with certain
limited exceptions) to vote the interests constituting the Basic Ownership,
notwithstanding the ownership of such interests by the Company. Since the
Sellers maintain the economic benefit of the Basic Ownership, and the Company
has not received, nor expects to receive in the future, any economic benefit
from BII or VVLC, the Company has not maintained these balances in its
consolidated financial statements since the Acquisition.

     The BII financial information includes the accounts of VVLC. The following
is a summary of financial information pertaining to BII and VVLC for the
Predecessor Company for the year ended December 31, 1994:

7.  PENSION AND OTHER EMPLOYEE BENEFITS

     Annual pension costs and liabilities for the Company under its two
defined-benefit plans covering all of its employees are determined by actuaries
using various methods and assumptions. The Company has agreed to voluntarily
contribute such amounts as are necessary to provide assets sufficient to meet
the benefits to be paid to its employees. The Company's present intent is to
make annual contributions, which are actuarially computed, in amounts not more
than the maximum nor less than the minimum allowable under the Internal Revenue
Code. For purposes of determining annual expenses and funding contributions, the
following assumptions were used for the years ended December 31:

     Plan assets at December 31, 1996 and 1995 consist primarily of fixed income
investments and equity investments.

       The Company offers defined-contribution plans for its employees with the
employees generally contributing from 1% to 15% of their compensation. Aggregate
contributions by the Company to such plans were $0.4 million and $0.2 million in
1996 and 1995, respectively. Aggregate contributions by the Predecessor Company
for such plans were $0.1 million for the period from January 1, 1995 through
April 20, 1995 and none for 1994.

     In addition to providing pension benefits, PCAC provides certain health 
care and life insurance benefits for retired employees. Substantially all of
PCAC's employees may become eligible for those benefits if they reach normal
retirement age while working for the Company. The following table presents the
plan's funded status reconciled with amounts recognized in the Company's balance
sheet at December 31:

</TABLE>

     The weighted-average annual assumed rate of increase in the per capita cost
of covered benefits (i.e., health care cost trend rate) is 10.0% for 1996 (the
same as the rate previously assumed for 1995 and 1994) and is assumed to
decrease gradually to 6% for 2010 and remain at that level thereafter. The
health care cost trend rate assumption has a significant effect on the amounts
reported. For example, increasing the assumed health care cost trend rates by
one percentage point in each year would increase the accumulated post-retirement
benefit obligation as of December 31, 1996, 1995 and 1994 by $0.8 million, $0.7
million, and $0.6 million, respectively, and the aggregate of the service and
interest cost components of the net periodic post-retirement benefit cost for
each of 1996, 1995 and 1994 by $0.1 million.


     The weighted-average discount rate used in determining the accumulated
post-retirement benefit obligation was 7.5% at December 31, 1996, 1995, and
1994.


     As a result of the Acquisition, the unrecognized net loss and unrecognized
transition obligation amounts as of that date were recognized.


     8.  BANK CREDIT FACILITY

     In April 1995, the Company entered into a credit agreement which provides
for the three-year Bank Credit Facility with Bank of America, Illinois ("BAI").
The Company may borrow up to $30.0 million, subject to certain borrowing base
limitations. At December 31, 1996, no amounts were outstanding under the Bank
Credit Facility. The revolving loans bear interest at a rate equal to, at the
Company's option, (i) the reference rate set by BAI or (ii) the LIBOR Base Rate.
The Bank Credit Facility requires the Company to pay a fee equal to one half of
one percent per annum on the total unused balance. Indebtedness outstanding
under the Bank Credit Facility is collateralized by a security interest in all
of the inventory, accounts receivable and certain other assets of PCAC and
All-Pure. Up to $10.0 million of the Borrowing Base, as defined by the Bank
Credit Facility, can be utilized for letters of credit. The Borrowing Base at
December 31, 1996 was approximately $18.6 million. After consideration of
applicable outstanding letters of credit of approximately $2.9 million, the
unused availability of the Borrowing Base was approximately $15.7 million at
December 31, 1996.



     The Bank Credit Facility contains restrictive covenants that, among other
things and under certain conditions, limit the ability of the Company to incur
additional indebtedness, to acquire or dispose of assets or operations and to
pay dividends or redeem shares of stock.

     As part of the Acquisition in April 1995, the Company issued and sold $135
million of 13 3/8% Senior Notes due in 2005. In January 1996, the Company
exchanged, as part of a public offering, the $135 million of Notes for $135
Million of 13 3/8% First Mortgage Notes due in 2005. Like the Senior Notes, the
Mortgage Notes are senior secured obligations of the Company, ranking senior in
right of payment to all subordinated indebtedness. The Mortgage Notes are fully
and unconditionally guaranteed on a joint and several basis by all of the
Company's direct and indirect wholly-owned subsidiaries and are secured by
first mortgage liens on certain manufacturing facilities. The Company is a
holding company with no operating assets or operations. Financial statements of
the Company's direct and indirect wholly-owned subsidiaries are not separately
included as the Company's management does not believe this information would be
material to investors.
        
     The Mortgage Notes are redeemable at the Company's option starting in 2000.
Before 1998, the Company may redeem a maximum of $35 million of the Mortgage
Notes at 113% of the principal amount due with funds from a public offering of
common stock of the Company or PCI (to the extent such funds are contributed to
the Company). Upon a change of control, as defined in the agreement, the Company
is required to offer to purchase the Mortgage Bonds for 101% of the principal
due.

     The Mortgage Notes and other long-term debt contain various restrictions on
the Company, which, among other things, limit the ability of the Company to
incur additional indebtedness, to acquire or dispose of assets or operations and
to pay dividends or redeem shares of stock.

10.  FINANCIAL INSTRUMENTS


CONCENTRATION OF CREDIT RISK

     The Company manufactures and sells chlorine and caustic-based products to
companies in diverse industries. The Company performs periodic credit
evaluations of its customers' financial condition and generally does not require
collateral. The Company's sales are primarily to customers in the western and
southeastern regions of the United States. Credit losses relating to these
customers have been within management's expectations.

     The Company maintains cash deposits with major banks, which from time to
time may exceed federally insured limits. The Company periodically assesses the
financial condition of the institutions and believes that any possible loss is
minimal.

                                       25
<PAGE>   26

     Net sales of the Company included sales to a major customer of
approximately $23.5 million for the year ended December 31, 1996. Net sales of
the Predecessor Company included sales to a major customer of approximately $7.5
million for the period from January 1, 1995 through April 20, 1995 and $18.7
million in 1994.

INVESTMENTS

     It is the policy of the Company to invest its excess cash in investment
instruments or securities whose value is not subject to market fluctuations such
as master notes of issuers rated at the time of such investment of at least
"A-2" or the equivalent thereof by S&P or at least "P-2" or the equivalent
thereof by Moody's or any bank or financial institution party to the Company's
Bank Credit Facility with Bank of America.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     In preparing disclosures about the fair value of financial instruments, the
Company has assumed that the carrying amount approximates fair value for cash
and cash equivalents, receivables, short-term borrowings, accounts payable and
certain accrued expenses because of the short maturities of those instruments.
The fair values of long-term debt instruments are estimated based upon quoted
market values (if applicable), or on the current interest rates available to the
Company for debt with similar terms and remaining maturities. Considerable
judgment is required in developing these estimates and, accordingly, no
assurance can be given that the estimated values presented herein are indicative
of the amounts that would be realized in a free market exchange. The Company
held no derivative financial instruments as of December 31, 1996 and 1995.


     At December 31, 1996, the fair market value of all of the Company's
financial instruments approximated the book value, except its 13 3/8% First
Mortgage Notes Due 2005, which had a book value of $135 million and a fair value
based upon its current quoted market price of $153 million.

11. COMMITMENTS AND CONTINGENCIES.

LETTERS OF CREDIT

     At December 31, 1996 the Company had letters of credit and performance
bonds outstanding of approximately $5.2 million and $2.5 million, respectively.
These letters of credit and performance bonds were issued for the benefit of:
customers under sales agreements securing delivery of products sold, a power
company as a deposit for the supply of electricity, and a state environmental
agency as required for manufacturers in the state. The letters of credit expire
at various dates in 1997 and 1998. No amounts were drawn on the letters of
credit at December 31, 1996.

OPERATING LEASES

     The Company leases certain manufacturing and distribution facilities,
computer equipment, and administrative offices under noncancelable leases.
Minimum future rental payments on such leases with terms in excess of one year
in effect at December 31, 1996 are as follows (in thousands):

     Lease expense charged to operations for the year ended December 31, 1996
and for the period from Inception through December 31, 1995 was
approximately $7.8 million and $6.3 million, respectively. Lease expense charged
to the Predecessor Company's operations for the period from January 1, 1995
through and the year ended December 31, 1994 was approximately $3.3 million 
and $8.4 million, respectively.

LITIGATION

     During 1993, Imperial West was awarded $1.4 million as the result of a
breach of contract claim it had asserted against the lessor of one of the
Imperial West plants. Appeals of the judgment were upheld and the award together
with interest was paid in January 1996. The consolidated financial statements at
December 31, 1995 included a receivable for the award. The lessor also filed
suit alleging that Imperial West was required to remediate alleged contamination
prior to the termination of the lease in July 1995. The parties settled that
action under terms pursuant to which (i) Imperial West paid the lessor $900,000
upon the termination of the lease in July 1995, and (ii) the lessor transferred
title to the property to Imperial West. In addition, Imperial West agreed to
indemnify the lessor against any future environmental liability with respect to
the property. Certain insurers paid a portion of Imperial West's defense costs
in connection with the lawsuit by the lessor.

     In 1994, the trustee in the bankruptcy of a company which was a customer of
the Predecessor Company filed suit against the Predecessor Company, seeking the
recovery of up to $2.2 million in payments made to the Predecessor Company on a
basis which the trustee alleges was preferential to other creditors' claims.
Management has been advised by counsel that the range of any loss which may be
incurred as the result of the suit will be


                                       27
<PAGE>   28

substantially below the amount claimed, and the Company is vigorously contesting
the action. The Company does not believe this action will have a significant
effect on its financial position or results of operations.


     The Company is party to other legal proceedings and potential claims
arising in the ordinary course of its business. In the opinion of management,
the Company has adequate legal defenses and/or insurance coverage with respect
to these matters and management does not believe that they will materially
affect the Company's operations or financial position.


12.  INCOME TAXES

     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the deferred tax liabilities and assets are as follows at December 31:

     At December 31, 1996, PCI had available to it on a consolidated tax return
basis approximately $35.6 million of net operating loss carryforward ("NOL") for
income tax purposes (expiring 2003 to 2010). The NOL is available for offset
against future taxable income if generated during the carryforward period. A tax
sharing agreement provides that the Company will be liable to PCI for its
separate tax liability only to the extent the consolidated group has a tax
liability. However as long as PCI's NOL is available to the consolidated group
to reduce taxable income, the Company's tax liability to PCI will be
substantially reduced. As a result of the tax sharing agreement, the NOL is
reflected by the Company for financial reporting purposes.

     For the year ended December 31, 1996 and the period from Inception through
December 31, 1995, the benefit of the utilization of the NOL of $11.5 million
and $3.6 million, respectively was recognized as an increase to additional
paid-in capital. Approximately $13.6 million was recognized as an increase to
additional paid-in capital as part of the purchase price allocation of the
Acquisition.

13.  OTHER LONG-TERM LIABILITIES--ENVIRONMENTAL

     The Company's operations are subject to extensive environmental laws and
regulations related to protection of the environment, including those applicable
to waste management, discharge of pollutants into the air and water, clean-up
liability from historical waste disposal practices, and employee health and
safety. At several of the Company's facilities, investigations or remediations
are underway and at some of these locations regulatory agencies are considering
whether additional actions are necessary to protect or remediate surface or
groundwater resources, and the Company could be required to incur additional
costs to construct and operate remediation systems in the future. In addition,
at several of its facilities, the Company is in the process of replacing or
closing ponds for the collection of wastewater. The Company plans to spend
approximately $1.3 million during the next fifteen years for closure of eight
chlor-alkali waste water disposal ponds at the Henderson plant. The Company 
believes that it is in substantial compliance with existing governmental 
regulations.

     PCAC's Henderson plant is located within what is known as the "Basic
Complex." Soil and groundwater contamination have been identified within and
adjoining the Basic Complex, including land owned by PCAC. A groundwater
treatment system was installed at the facility in 1983 and, pursuant to a
Consent Agreement with the Nevada Division of Environmental Protection, a study
is being conducted to further evaluate soil and groundwater contamination at
the facility and other properties within the Basic Complex and to determine
whether additional remediation will be necessary with respect to PCAC's
property.   

     In connection with the October 1988 acquisition of the chlor-alkali
business by the Predecessor Company, ICI Delaware Holdings, Inc. and ICI
Americas, Inc. (such companies or their successors, the "ZENECA Companies")
agreed to indemnify the Predecessor Company for certain environmental
liabilities (the "ZENECA Indemnity"), including liabilities associated with
operations at the Company's plant located in Henderson, Nevada (the "Henderson
Plant"). In general, the ZENECA Companies agreed to indemnify the Predecessor
Company from environmental costs which arise from or relate to pre-closing
actions which involved disposal, discharge, or release of materials resulting
from non-chlor-alkali manufacturing operations at the Henderson Plant and at
other properties within the same industrial complex. Payments under the
indemnity cannot exceed approximately $65 million.

     Due to the change in ownership resulting from the Acquisition, the ZENECA
Indemnity will terminate on April 20, 1999. The ZENECA Indemnity will continue
to cover claims after the expiration of the term of the indemnity provided that,
prior to the expiration of the indemnity, proper notice to the ZENECA Companies
is given and the Company has taken certain other actions. The Company believes
that the ZENECA Companies will continue to honor their obligations under the
ZENECA Indemnity for claims properly presented by the Company. It is possible,
however, that disputes could arise between the parties and that the Company
would have to subject its claims for clean-up expenses, which could be
substantial, to the contractually established arbitration process. In the
opinion of management, any environmental liability in excess of the amount
indemnified and accrued on the consolidated balance sheet, if any, would not
have a material adverse effect on the consolidated financial statements.


                                       29
<PAGE>   30

     In the Acquisition Agreement, the Sellers agreed to indemnify the Company
for certain environmental liabilities that result from certain discharges of
hazardous materials, or violations of environmental laws, arising prior to April
20, 1995 (the "Closing Date") from or relating to the Pioneer plant sites or
arising before or after the Closing Date with respect to certain environmental
liabilities relating to certain properties held for the benefit of the Sellers
("Sellers' Indemnity"). Amounts payable pursuant to the Sellers' Indemnity will
generally be payable as follows: (i) out of certain reserves established on the
Predecessor Company's balance sheet at December 31, 1994; (ii) either by offset
against the amounts payable under the Seller Notes or from amounts held pursuant
to the Contingent Payment Agreement, and (iii) in certain circumstances and
subject to specified limitations, out of the personal assets of the Sellers.
Subject to certain exceptions and limitations set forth in the Acquisition
Agreement, a claim notice with respect to amounts payable pursuant to the
Sellers' Indemnity must generally be given within 15 years of the Closing Date.
PCI is required to reimburse the Sellers for amounts paid under the Sellers'
Indemnity with amounts recovered under the ZENECA Indemnity or from other third
parties. PCI and the Sellers have agreed that they will cooperate in matters
relating to the ZENECA Indemnity.

     Remediation costs are accrued based on estimates of known environmental
remediation exposure. Such accruals are based upon management's best estimate of
the ultimate cost and are recorded even if significant uncertainties exist over
the ultimate cost of the remediation. Ongoing environmental compliance cost,
including maintenance and monitoring costs, are charge to operations as
incurred. The liabilities are based upon all available facts, existing
technology, past experience and cost-sharing arrangements, including the
viability of other parties. Charges made against income for recurring
environmental matters, included in "cost of sales" on the statements of
operations, totaled approximately $1.7 million and $1.2 million for the year
ended December 31, 1996 and for the period from Inception through December
31, 1995, respectively, and $0.4 million and $1.8 million for the Predecessor
Company for the period from January 1, 1995 through April 20, 1995 and the year
ended December 31, 1994, respectively. Capital expenditures for
environmental-related matters at existing facilities were approximately $4.3
million and $2.2 million for the year ended December 31, 1996 and for the period
from Inception through December 31, 1995, respectively, and $0.2 million
and $0.5 million for the Predecessor Company for the period from January 1, 1995
through April 20, 1995 and the year ended December 31, 1994, respectively.
Future environmental-related capital expenditures will depend upon regulatory
requirements, as well as timing related to obtaining necessary permits and
approvals.

     Estimates of future environmental restoration and remediation costs are
inherently imprecise due to currently unknown factors such as the magnitude of
possible contamination, the timing and extent of such restoration and
remediation, the extent to which such costs are recoverable from third parties,
and the extent to which environmental laws and regulations may change in the
future. The Predecessor Company established a reserve of approximately $9.0
million at the time of its acquisition of its Henderson, Nevada and St. Gabriel,
Louisiana facilities with respect to potential remediation costs relating to
matters not covered by the ZENECA Indemnity, consisting primarily of remediation
costs that may be incurred by the Company for chlor-alkali-related remediation
of the Henderson and St. Gabriel facilities. The recorded accrual included
certain amounts related to anticipated closure and post-closure actions that may
be required in the event that operation of the present chlor-alkali plants
ceases. Such accrual is recorded in the Company's consolidated balance sheets at
December 31, 1996 and 1995. However, complete analysis and study has not been
completed and therefore additional future charges may be recorded at the time a
decision for closure is made.

     In 1994, the Predecessor Company recorded an additional $3.2 million
environmental reserve related to pre-closing actions at sites that are the
responsibility of the ZENECA Companies. Such accrual is recorded in the
Company's consolidated balance sheets at December 31, 1996 and 1995. Other 
assets include an account receivable of the same amount from the ZENECA
Companies. The Company believes it will be reimbursed by the ZENECA Companies
for substantially all of such costs that are incurred at the Henderson Plant and
other properties within the same industrial complex. Additionally, certain other
environmental matters exist which have been assumed directly by the ZENECA
Companies. No assurance can be given that actual costs will not exceed accrued
amounts or the amounts currently estimated. The imposition of more stringent
standards or requirements under

                                       30
<PAGE>   31

environmental laws or regulations, new developments or changes respecting site
cleanup costs, or a determination that the Company is potentially responsible
for the release of hazardous substances at other sites could result in
expenditures in excess of amounts currently estimated by the Company to be
required for such matters. Further, there can be no assurance that additional
environmental matters will not arise in the future.

14.  RELATED PARTY TRANSACTIONS

     The Company has a 15% partnership interest in Saguaro Power Company
("Saguaro"), which owns a cogeneration plant located in Henderson, Nevada. The
Company's interest in Saguaro is accounted for using the cost method of
accounting. The Company sells certain products and services to and purchases
steam from Saguaro at market prices. Transactions with Saguaro are as follows:

     Accounts receivable from and accounts payable to Saguaro are at the
Company's normal terms and are generally not significant to the Company's
consolidated balance sheet.

     The Company is a party to an agreement negotiated on an arms-length basis
with BII for the delivery of the Company's water to the Henderson production
facility. The agreement provides for the delivery of a minimum of eight million
gallons of water per day. The agreement expires on December 31, 2014, unless
terminated earlier in accordance with the provisions of the agreement. For the
year ended December 31, 1996 and the period from Inception through December 31,
1995, BII charged expenses to the Company of approximately $0.2 million and $0.2
million, respectively. For the period from January 1, 1995 through April 20,
1995 and the year ended December 31, 1994, BII charged expenses to the
Predecessor Company of approximately $0.2 million and $0.5 million,
respectively.

     The Company sells certain products to Kemwater at market prices. Sales to
Kemwater totaled $8.8 million during the year ended December 31, 1996. Kemwater
provides transportation services to the Company at market prices which totaled
$1.8 million for 1996.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
         FINANCIAL DISCLOSURE.

     Deloitte & Touche LLP has acted as independent accountants of the Company
since its inception. Following the Acquisition it was determined that Deloitte &
Touche LLP would continue to act as independent accountants of the Company and
its consolidated subsidiaries.

     Ernst & Young LLP had been the independent accountants for Pioneer Americas
and its consolidated subsidiaries prior to its dismissal, effective October 16,
1995. The reports of Ernst & Young LLP on the financial statements of Pioneer
Americas for the fiscal year ended December 31, 1994 did not contain an adverse
opinion or a disclaimer of opinion and were not qualified or modified as to
uncertainty, audit scope or accounting principles. In connection with the audits
of the financial statements of Pioneer Americas the fiscal year ended December
31, 1994, and in the subsequent interim period, there were no disagreements with
Ernst & Young LLP on any matters of accounting principles or practices,
financial statement disclosure or auditing scope and procedures which, if not
resolved to the satisfaction of Ernst & Young LLP, would have caused Ernst &
Young LLP to make reference to the matter in their report.

     Ernst & Young LLP furnished a letter addressed to the Securities and
Exchange Commission stating whether it agreed with the above statements. A copy
of that letter, dated October 30, 1995, is filed as an exhibit to this Annual
Report.

                         EXECUTIVE EMPLOYMENT AGREEMENT

                 This EXECUTIVE EMPLOYMENT AGREEMENT is made and entered into
between Pioneer Companies, Inc., a Delaware corporation (the "Company"), and
Michael J. Ferris, (the "Executive") as of January 4, 1997.

                              W I T N E S S E T H:

                 WHEREAS, the Company desires to employ the Executive, and the
Executive desires to accept employment with the Company, on the terms and
conditions set forth herein;

                 NOW, THEREFORE, on the basis of the foregoing premises and in
consideration of the mutual covenants and agreements contained herein, the
parties hereto agree as follows:

                 SECTION 1.        Employment.  The Company hereby agrees to
employ the Executive and the Executive hereby accepts employment with the
Company, on the terms and subject to the conditions hereinafter set forth.
Subject to such terms and conditions, the Executive shall serve as President
and Chief Executive Officer of the Company and, in such capacity, shall report
directly to the Board of Directors of the Company (the "Board of Directors")
and shall have such duties, functions, responsibilities and authority as are
consistent with the Executive's position as the senior executive officer in
charge of the general management, business and affairs of the Company and
subsidiaries of the Company including, but not limited to, the development and
implementation of strategies and goals and internal policies and program
designed to achieve the profit, market share and product mix goals of the
Company and its subsidiaries, together with such additional duties, functions,
responsibilities and authority including, without limitation, serving as an
officer and/or director of any subsidiary of the Company, commensurate with the
Executive's position as set forth in this Agreement, as may be assigned to the
Executive from time to time by the Board of Directors.  The Company shall use
best efforts to have the Executive nominated to the Board of Directors.

                 SECTION 2.        Term.  Subject to the provisions and
conditions of this Agreement (including Section 6), the Executive's employment
hereunder shall commence on the date hereof and shall continue during the
period ending on the third anniversary of the date hereof (the "Employment
Term").

                 SECTION 3.        Compensation.

                (a)    Salary.  As compensation for the performance of the
Executive's services hereunder, the Company shall pay to the Executive a base
salary (the "Salary") of Three Hundred Fifty Thousand Dollars ($350,000) per
annum with increases, if any, as may be approved in writing by the Board of
Directors.  The Salary shall be payable in accordance with payroll
<PAGE>   2
practices of the Company as the same shall exist from time to time.  In no
event shall the Salary be decreased during the Employment Term.

               (b)     Bonus Plan.  The Executive shall be entitled to
receive bonus compensation consisting of cash, securities or property ("Bonus")
in accordance with any management incentive plan or plans (including, without
limitation, any shared earnings plan) which may be established by the Board of
Directors of the Company for its executive officers and management.
Notwithstanding the foregoing, the Executive shall be entitled to receive a
cash bonus of not less than Two Hundred Thousand Dollars ($200,000) in
consideration of services to be rendered to the Company in 1997, such bonus to
be paid quarterly in arrears during 1997.

               (c)     Benefits.  In addition to the Salary and Bonus, the
Executive shall be entitled to participate in or to receive the same health,
insurance, pension, automobile, severance, vacation, holiday, sick leave,
disability, profit sharing, 401(k) savings and other benefits as shall be
provided to executive officers of the Company generally.

               (d)     Paying Entity.  The Company may cause any one or more
of its subsidiaries to provide the salary and benefits to the Executive as are
required by this Agreement.

               SECTION 4.    Exclusivity.  During the Employment Term,
the Executive shall devote substantially all of his time to the business of the
Company, shall faithfully serve the Company, shall in all respects conform to
and comply with the lawful directions and instructions given to him by the
Board of Directors or its designee in accordance with the terms of this
Agreement, shall use his best efforts to promote and serve the interests of the
Company and shall not engage in any other business activity, whether or not
such activity shall be engaged in for pecuniary profit, except that the
Executive may engage in personal investing and charitable activities that do
not interfere in any material respect with the services to be provided by the
Executive hereunder.

               SECTION 5.    Reimbursement for Expenses.  The Company
shall promptly reimburse the Executive for all reasonable out-of-pocket travel,
entertainment and other business expenses incurred by the Executive during the
term of this Agreement and in the performance of his duties hereunder in
accordance with the Company's reimbursement policies in effect from time to
time.

               SECTION 6.    Termination.

               (a)     Death.  This Agreement shall automatically terminate
upon the death of the Executive and upon such event, the Executive's estate
shall be entitled to receive the amounts specified in Section 6(f) below.

               (b)     Disability.  If the Executive is unable to perform
the duties required of him under this Agreement because of physical or mental
disability, this Agreement shall remain in full force and effect and the
Company shall pay all compensation required to be paid to the Executive
hereunder, unless the Executive is unable to perform the duties required of him
under


                                     -2-
<PAGE>   3




this Agreement for an aggregate of ninety (90) days (whether or not
consecutive) during any twelve (12) month period during the term of this
Agreement, in which event this Agreement (other than Sections 7, 8, 9 and 12
hereof), including, but not limited to, the Company's obligations to pay any
Salary or to provide any privileges under this Agreement, shall, upon written
notice by the Company to the Executive to such effect, terminate; provided,
however, that the foregoing shall not prejudice the Executive's rights to
continuing, existing insurance benefits for which he is otherwise eligible,
including disability benefits.  In case of any dispute as to whether the
Executive is disabled within the meaning of this Section 6(b), the
determination of such disability for the period specified shall be certified by
a physician reasonably acceptable to both the Company and the Executive, which
physician's determination shall be final and binding on the parties hereto.
The Company shall be permitted to hire a replacement of the Executive, so long
as this Agreement shall remain in effect, to serve in the event and for so long
as the Executive shall be unable to perform the duties required of him
hereunder due to his disability for an aggregate of thirty (30) days during any
12-month period during the term of this Agreement.

              (c)      Cause.  The Company may terminate this Agreement
(other than Sections 7, 8, 9 and 12 hereof) for "Cause."  For purposes of this
Agreement, "Cause" shall mean: (i) the Executive's failure, neglect or refusal
to perform his duties hereunder which failure, neglect or refusal shall not
have been corrected by the Executive within thirty (30) days of receipt by the
Executive of written notice from the Company of such failure, neglect or
refusal, which notice shall set forth the nature of said failure, neglect or
refusal; (ii) any engagement by the Executive in misconduct that is materially
injurious to the reputation or business of the Company or its affiliates or
that materially impairs the ability of the Executive to perform his duties and
responsibilities hereunder; (iii) conviction of the Executive for the
commission of a felony; or (iv) the commission by the Executive of an act of
fraud or embezzlement against the Company.  If the Executive's employment is
terminated for Cause, the Executive shall be entitled to receive the amounts
specified in Section 6(f) hereof.  In the event of any termination pursuant to
this Section 6(c),the Company shall deliver to the Executive written notice
setting forth the basis for such termination, which notice shall set forth the
nature of the Cause, and the facts and circumstances in connection therewith,
which is the reason for such termination.

              (d)      Good Reason.  The Executive may terminate this
Agreement for "Good Reason" following a Substantial Breach (as defined below)
if such Substantial Breach shall not have been corrected by the Company within
thirty (30) days of receipt by the Company of written notice from the Executive
of the occurrence of such Substantial Breach, which notice shall specifically
set forth the nature of the Substantial Breach which, if not corrected, will
entitle the Executive at any time after such thirty (30) day notice period and
by subsequent written notice to terminate this Agreement.  In the event of
resignation by the Executive following a Substantial Breach, the Executive
shall be entitled to receive the amounts specified in Section 6(f) hereof.  An
election by the Executive to terminate his employment under this paragraph
shall not be a breach of this Agreement.  The term "Substantial Breach" means
any material breach by the Company of its obligations hereunder consisting of:
(i) the failure of the Company to pay the Executive the Salary or Bonus, if
any, in accordance with Section 3(a) and (b) hereof; (ii) the failure by the
Company to substantially maintain and continue the Executive's participation in





                                      -3-
<PAGE>   4




benefit plans as provided in Section 3(c) hereof; or (iii) any material
diminishment in the duties or responsibilities of the Executive described in
Section 1; provided, however, that the term "Substantial Breach" shall not
include a termination of the Executive's employment hereunder pursuant to
Section 6(b) or (c) hereof.  The date of termination of the Executive's
employment under this Section 6(d) shall be the effective date of any
resignation specified in writing by the Executive, which shall not be less than
sixty (60) days after receipt by the Company of written notice of such
resignation, provided that any resignation by the Executive shall not be
effective pursuant to this Section 6(d) if such Substantial Breach shall have
been corrected by the Company during the thirty (30) day period following
notice by the Executive of the existence thereof or if corrected thereafter
prior to the date of resignation by the Executive.

              (e)       Without Cause.  The Company, by action of its Board
of Directors, may terminate this Agreement (other than Sections 7, 8, 9 and 12
hereof) without Cause upon the giving to the Executive of thirty (30) days'
prior written notice of such termination.  If the Executive's employment is
terminated by the Company without Cause, the Executive shall be entitled to
receive the amounts specified in Section 6(f) hereof.

              (f)       Payments.  In the event that the Executive's
employment hereunder terminates for any reason, the Company shall promptly pay
to the Executive all amounts accrued but unpaid hereunder through the date of
termination in respect of the Salary and for reimbursement of any expenses
pursuant to Section 5 hereof, and, in the case of any termination by reason of
death or physical or mental disability of the Executive pursuant to Section
6(a) or 6(b) hereof, a pro rated portion of the Bonus, if any, which the
Executive would have been otherwise entitled to receive under Section 3(b) for
the calendar year in which such termination occurs, such pro rated portion
being the portion of such Bonus corresponding to the period commencing on
January 1 of such year and ending on the date of termination.  In the event
that the Executive's employment has been terminated by the Company for Cause,
the Company shall have no obligations to the Executive for Salary, Bonus or
other benefits herein provided accruing on or after the date of termination
except as set forth in the preceding sentence or as may be otherwise provided
by law.  In the event that the Executive's employment hereunder is terminated
by the Company without Cause or by the Executive with Good Reason, in addition
to the amounts specified in the first sentence of this Section 6(f), the
Executive shall continue to receive the Salary at the rate in effect hereunder
on the date of such termination periodically, in accordance with the Company's
prevailing payroll practices, until the last date of the Employment Term or
until the first anniversary of the termination date, if longer, plus (i) the
cost of the Executive's premiums for health care benefits under COBRA or the
cost of the Executive's premiums under any replacement health insurance
coverage obtained by the Executive containing substantially the same coverage
as provided to the Executive at such time, which premiums shall be payable as
and when the Salary would otherwise have been payable as provided in this
Agreement; and (ii) a pro rated portion of the Bonus, if any, which the
Executive would have otherwise been entitled to receive under Section 3(b) for
the calendar year in which the Executive is terminated pro rated in the same
manner as set forth in the first sentence of this Section 6(f).  Without
intending to limit the generality of Section 7, in the event that the Executive
accepts other employment or engages in his own business prior to the last date
of the Employment Term, the Executive shall forthwith notify the Company and
the Company shall be





                                      -4-
<PAGE>   5




entitled to set off from amounts due the Executive under this Section 6(f) the
amounts paid to the Executive in respect of such other employment or business
activity. Upon any termination of this Agreement, all of the rights, privileges
and duties of the Executive hereunder shall cease except for any rights under
this Section 6(f) and any obligations under Sections 7, 8, 9 and 12 hereunder.

          SECTION 7.       Secrecy and Non-competition.

         (a)       No Competing Employment.  The Executive acknowledges that 
the agreements and covenants contained in this Section 7 are essential to
protect the value of the Company's business and assets and that by virtue of
his employment with the Company, the Executive will obtain Confidential
Information and there is a substantial probability that such Confidential
Information could be used to the substantial advantage of a competitor of the
Company or its subsidiaries and to the Company's or its subsidiaries'
substantial detriment.  Therefore, the Executive agrees that except in
connection with his employment hereunder or as required by legal process, he
shall not disclose to any person or entity or use, during the Employment Term
or at any time thereafter, any information not in the public domain or
generally known in the industry, in any form acquired by the Executive while
employed by the Company or, if acquired following the Employment Term, such
information which, to the Executive's knowledge, has been acquired, directly,
or indirectly, from any person or entity owing a duty of confidentiality to the
Company or any of its subsidiaries or affiliates, relating to the Company, its
subsidiaries or affiliates, including but not limited to information regarding
customers, vendors, suppliers, trade secrets, training programs, manuals or
materials, technical information, contracts, systems, procedures, mailing
lists, know-how, trade names, improvements, price lists, financial or other
data (including the revenues, costs or profits associated with any of the
Company's products or services), business plans, code books, invoices and other
financial statements, computer programs, software systems, databases, discs and
printouts, plans (business, technical or otherwise), customer and industry
lists, correspondence, internal reports, personnel files, sales and advertising
material, telephone numbers, names, addresses or any other compilation of
information, written or unwritten, which is or was used in the business of the
Company or any of its subsidiaries or affiliates (collectively, "Confidential
Information").  The Executive agrees and acknowledges that all Confidential
Information, in any form, and copies and extracts thereof, are and shall remain
the sole and exclusive property of the Company and upon termination of his
employment with the Company, the Executive shall return to the Company the
originals and all copies of any Confidential Information provided to or
acquired by the Executive in connection with the performance of his duties for
the Company, and shall return to the Company all files, correspondence and/or
other communications received, maintained and/or originated by the Executive
during the course of his employment.

         (b)       No Interference.  During the term of this Agreement and 
for a period of two (2) years following the date of the termination of the
Executive's employment with the Company (the "Restricted Period"), the
Executive shall not, whether for his own account or for the account of any
other individual, partnership, firm, corporation or other business organization
(other than the Company), directly or indirectly, solicit, endeavor to entice
away from the Company, its affiliates or subsidiaries, or otherwise directly
interfere with the relationship of the Company, its affiliates or subsidiaries
with any person who, to the knowledge of the Executive,





                                      -5-
<PAGE>   6




is employed by or otherwise engaged to perform services for the Company, its
affiliates or subsidiaries (including, but not limited to, any independent
distributor or sales representative or organization).

         (c)      Inventions.  The Executive hereby sells, transfers and 
assigns to the Company, or to any person or entity designated in writing by
the Company, all of the right, title and interest of the Executive in and to
all inventions, sales materials, software, training materials, disclosures and
improvements, whether patented or unpatented, and copyrightable material, made
or conceived by the Executive, solely or jointly, in whole or in part, during
his employment with the Company which are not generally known to the public or
the industry or recognized as standard practice and which (i) relate to
services, trade names, methods, ideas, apparatus, designs, products, processes
or devices which may be sold, leased, used or under construction or development
by the Company, or any franchise affiliated with the Company and (ii) arise
(wholly or partly) from the efforts of the Executive during and in the course
of his employment with the Company (an "Invention").  The Executive shall
communicate promptly and disclose to the Company, in such form as the Company
reasonably requests, all information, details and data pertaining to any such
Invention.  With respect to all Inventions which are to be assigned pursuant to
this Section 7, the Executive will assist the Company in any reasonable manner
to obtain for the Company's benefit patents thereon, including, but not limited
to, executing patent applications, transfers or assignments thereof to the
Company and any and all other documents reasonably deemed necessary by the
Company.  The Company shall pay all costs incident to the preparation,
execution and delivery of such patent applications, transfers, assignments and
other documents.  Any Invention by the Executive within six (6) months
following the termination of his employment hereunder shall be presumed to fall
within the provisions of this Section 7(c) unless the Executive bears the
burden of proof of showing that the Invention was first conceived and made
following such termination.

         SECTION 8.           Injunctive Relief.  Without intending to limit 
the remedies available to the Company, the Executive acknowledges that a
breach of any of the covenants contained in Section 7 hereof may result in
material irreparable injury to the Company or it subsidiaries or affiliates for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of such a
breach or threat thereof, the Company shall be entitled to seek a temporary
restraining order and/or a preliminary or permanent injunction, restraining the
Executive from engaging in activities prohibited by Section 7 hereof or such
other relief as may be required specifically to enforce any of the covenants in
Section hereof.

          SECTION 9.          Extension of Restricted Period.  In addition 
to the remedies the Company may seek and obtain pursuant to Section 8
of this Agreement, the Restricted Period shall be extended by any and all
periods during which the Executive shall be found by a court to have been in
violation of the covenants contained in Section 7 hereof.

          SECTION 10.         Successors and Assigns; No Third-Party
Beneficiaries.  This Agreement shall inure to the benefit of, and be binding
upon, the parties hereto and their respective successors and assigns,
including, but not limited to, the Executive's heirs and





                                      -6-
<PAGE>   7




personal representatives of the Executive's estate; provided, however, that
neither party shall assign or delegate any of the obligations created under
this Agreement without the prior written consent of the other party.
Notwithstanding the foregoing, the Company shall have the unrestricted right to
assign this Agreement and to delegate all or any part of its obligations
hereunder to any of its subsidiaries, so long as such assignment does not
diminish the duties, function, responsibility or authority of the Executive or
result in any assignment of duties or responsibilities materially inconsistent
with those set forth in this Agreement (unless consented to by the Executive)
but in such event such assignee shall expressly assume all obligations of the
Company hereunder and the Company shall remain fully liable for the performance
of all such obligations in the manner prescribed in this Agreement.  Nothing in
this Agreement shall confer upon any person or entity not a party to this
Agreement, or (unless otherwise expressly provided herein) the legal
representatives of such person or entity, any rights or remedies of any nature
or kind whatsoever under or by reason of Agreement.

          SECTION 11.       Waiver and Amendments.  Any waiver, alteration, 
amendment or modification of any of the terms of this Agreement shall be valid
only if made in writing and signed by the parties hereto.  No waiver by either
of the parties hereto of their rights hereunder shall be deemed to constitute a
waiver with respect to any subsequent occurrences or transactions hereunder
unless such waiver specifically states that it is to be construed as a
continuing waiver.

          SECTION 12.       Severability and Governing Law.  The Executive 
acknowledges and agrees that the covenants set forth in Section 7 hereof are
reasonable and valid in all respects.  Each party hereto acknowledges and
agrees that if any of such covenants or other provisions of this Agreement are
found to be invalid or unenforceable by a final determination of a court of
competent jurisdiction (a) the remaining terms and provisions hereof shall be
unimpaired and (b) the invalid and unenforceable term or provision shall be
deemed replaced by a term or provision that is valid and enforceable and that
comes closest to expressing the intention of the invalid or unenforceable term
or provision.  THIS AGREEMENT SHALL BE GOVERNED BY AND INTERPRETED AND ENFORCED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO THE
CHOICE OF LAW PROVISIONS THEREOF.

          SECTION 13.       Notices.  All notices and other communications 
given or made pursuant hereto shall be in writing and shall be deemed to have
been duly given or made if delivered personally or sent by registered or
certified mail (postage prepaid, return receipt requested), or sent by

the Company, to Pioneer Companies, Inc., 4200 NationsBank Center, 700 Louisiana

                            STOCK PURCHASE AGREEMENT

              This STOCK PURCHASE AGREEMENT, dated as of January 4, 1997 (the
"Agreement"), between Pioneer Companies, Inc., a Delaware corporation (the
"Company"), and Michael J. Ferris (the "Purchaser").

              WHEREAS, pursuant to the Executive Employment Agreement (the
"Employment Agreement"), dated as of the date hereof, between the Company and
the Purchaser, the Company has agreed to employ the Purchaser, and the
Purchaser has agreed to be employed by the Company upon and subject to the
terms therein;

              WHEREAS, the Company desires to sell 150,000 shares (the
"Shares") of the Class A common stock, par value $.01 per share of the Company
(the "Common Stock") to the Purchaser; and

              WHEREAS, the Purchaser desires to purchase the Shares upon the
terms and subject to the conditions set forth in this Agreement;

              NOW, THEREFORE, in consideration of the mutual terms, conditions
and other agreements set forth herein, the parties hereto hereby agree as
follows:


              Section  1.    Sale and Purchase of Securities. (a) Subject 
to the terms and conditions set forth herein, on the Closing Date (as defined 
herein), the Company shall sell to the Purchaser and the Purchaser shall
purchase from the Company the Shares for a cash payment per share equal to the
average of the closing sale prices of the Common Stock as reported on the
NASDAQ National Market System on the days during which the Common Stock was
traded during the thirty (30) consecutive trading days immediately preceding
the date hereof (the "Purchase Price").

              (b)   The sale and purchase of the Shares shall be effected by 
the Company's execution and delivery to the Purchaser of a duly executed stock
certificate evidencing the Shares registered in his name, and by the delivery
by the Purchaser to the Company of the Purchaser's check in the amount of the
purchase price of the Shares.

              (c)   The closing of the transactions hereunder (the "Closing") 
shall take place on such day on or prior to the forty-fifth day (or if not a
business day the next succeeding business day) after the date hereof as
specified in a notice from the Company to the Purchaser (the "Closing Date").

              Section 2.     Representations and Warranties of the Company.  
The Company represents and warrants to the Purchaser as follows:

              (a)   Organization and Corporate Power.  The Company is a 
corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware, and has
<PAGE>   2
all requisite power and authority to execute, deliver and perform this
Agreement and to issue, sell and deliver the Shares hereunder.

              (b)            Authorization, Enforceability. All corporate action
on the part of the Company necessary for the authorization, execution and
delivery of this Agreement and the issuance, sale and delivery of the Shares
hereunder has been taken.  This Agreement has been duly authorized, executed
and delivered by the Company and constitutes the valid and legally binding
obligation of the Company, enforceable in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general principles of equity.

              Section 3.   Representations of the Purchaser.  The Purchaser 
hereby represents and warrants as follows:

              (a)            Validity of Agreement.  This Agreement has been 
duly executed by the Purchaser and constitutes the valid and binding obligation
of the Purchaser enforceable against the Purchaser in accordance with its
terms, except that such enforcement may be subject to applicable bankruptcy,
insolvency, moratorium or similar laws affecting the enforcement of creditors'
rights generally and general principles of equity.

              (b)           No Consents.  The execution, delivery and 
performance by the Purchaser of this Agreement does not require any consent or
approval of any person or entity.

              (c)           Investment Representations.

                            (i)     The Purchaser is acquiring the Shares solely
         for his own account as principal, for investment purposes only, and
         not with a view to, or for, subdivision, resale, distribution or
         fractionalization thereof, in whole or in part, or for the account, in
         whole or in part, of others, and no other person or entity has a
         direct or indirect beneficial interest in the Shares; further, the
         Purchaser intends to hold the Shares as an investment and does not
         presently anticipate any change in circumstances or other particular
         occasion or event that would cause him to attempt to sell any of the
         Shares;

                            (ii)    the Purchaser understands that no federal or
         state agency has made any finding or determination as to the fairness
         of this investment and that the sale of the Shares is intended to be
         exempt from registration both under the Securities Act of 1933, as
         amended (the "Securities Act"), and any applicable state securities
         law, and, in furtherance thereof, the Purchaser represents and
         warrants to, and agrees with, the Company that he has the financial
         ability to bear the economic risk of his investment, and has adequate
         means for providing for his current needs and personal contingencies
         and has no need for liquidity with respect to his investment in the
         Shares;

                            (iii)   the Purchaser has been given the opportunity
         to ask questions of, and receive information and answers from, the
         Company concerning matters pertaining to the Company and its business
         and affairs and this investment, and all such questions have

                                     -2-
<PAGE>   3
         been answered, and all such information has been provided, to his
         satisfaction and he has determined that the Shares are a suitable
         investment for him and that at this time he could bear the complete
         loss of his investment;

                          (iv)    the Purchaser is not relying on the Company
         in regard to the tax and other personal financial considerations
         related to this investment, and the Purchaser has, to the extent he
         deems it necessary, relied on the advice of, or has consulted with,
         only his own advisors;

                          (v)     the Purchaser will not sell or otherwise
         transfer the Shares without registration under the Securities Act, and
         applicable state securities laws or unless the Company has received an
         appropriate opinion of counsel reasonably acceptable to it that
         registration thereunder is not required, and fully understands and
         agrees that he must bear the economic risk of his purchase for an
         indefinite period of time because, among other reasons, the Shares
         have not been registered under the Securities Act or under any
         applicable state securities laws and, therefore, cannot be resold,
         pledged, assigned or otherwise disposed of unless they are
         subsequently registered under the Securities Act and any applicable
         state securities laws or an exemption from such registration is
         available.  The Purchaser understands that the Company is under no
         obligation to register the Shares on his behalf or to assist him in
         complying with any exemption from registration under the Securities
         Act or any state securities laws; and

                          (vi)    the Purchaser is a resident of the state
         specified for the Purchaser in Section 6 hereof.


                  Section 4. Legend.  Any certificates evidencing the Shares 
shall bear the following legend:

                          "The shares represented by this certificate have not
         been registered under the Securities Act of 1933, as amended (the
         "Act"), and may not be transferred or sold except pursuant to an
         effective registration statement under the Act or in a transaction
         which, in the opinion of counsel reasonably satisfactory to Pioneer
         Companies, Inc., qualifies as an exempt transaction under the Act and
         the rules and regulations promulgated thereunder."

 
                  Section 5. Condition to Obligations of the Parties. The 
obligations of the Company and the Purchaser to consummate the transactions
contemplated by this Agreement are subject to the continued effectiveness of
the transactions contemplated by the Employment Agreement as of the Closing
Date.

                  Section 6. Notices. All communications under this Agreement

modified or supplemented only by a written instrument executed by the parties
hereto.

                  Section 10.    Counterparts.  This Agreement may be

                             STOCK OPTION AGREEMENT
                                   UNDER THE
                            PIONEER COMPANIES, INC.
                           1995 STOCK INCENTIVE PLAN


                 THIS AGREEMENT, made as of the 4th day of January, 1997, by
and between Pioneer Companies, Inc., a Delaware corporation (the "Company") and
Michael J. Ferris (the "Optionee").

                             W I T N E S S E T H :

                 WHEREAS, the Optionee is now employed by the Company or a
"parent" or "subsidiary" of the Company (such terms, as used herein, shall be
as defined in 424(e) and (f) of the Internal Revenue Code of 1986, as amended
(the "Code")), and the Company desires to have him remain in such employment
and to afford him the opportunity to acquire, or enlarge, his ownership of the
Company's Class A Common Stock, par value $.01 per share ("Stock"), so that he
may have a direct proprietary interest in the Company's success;

                 NOW, THEREFORE, in consideration of the covenants and
agreements herein contained, the parties hereto hereby agree as follows:

                 1.  Grant of Option.  Subject to the terms and conditions set
forth herein and in the Company's 1995 Stock Incentive Plan (the "Plan"), the
Company hereby grants to the Optionee, during the period commencing on the date
of this Agreement and ending on January 4, 2007 (the "Termination Date"), the
right and option (the right to purchase any one share of Stock hereunder being
an "Option") to purchase from the Company, at a price of $5.00 per share, an
aggregate of 133,750 shares of Stock.  The Options granted hereunder shall be
"incentive stock options" within the meaning of Section 422 of the Code.

                 2.  Limitations on Exercise of Option.  (a)  Subject to the
terms and conditions set forth herein, the Optionee may exercise 20,000 of the
Options on January 4, 1998, with none being exercisable prior to such date, an
additional 20,000 on January 4, 1999, an additional 20,000 on January 4, 2000,
an additional 20,000 on January 4, 2001, an additional 20,000 on January 4,
2002, an additional 20,000 on January 4, 2003, and an additional 13,750 on
January 4, 2004.

                 (b)  Notwithstanding the limitations set forth in paragraph
2(a), 100% of the Options shall become immediately exercisable (i) in the event
of a change in control of the
<PAGE>   2
Company, or (ii) if Optionee's employment with the Company or a subsidiary
thereof, as the case may be, is terminated by the Company or a subsidiary
thereof, as the case may be, without Cause (as defined in paragraph 3 hereof).
For purposes of the preceding sentence, a "change of control" shall, unless the
Board of Directors of the Company (the "Board") otherwise directs by resolution
adopted prior thereto, be deemed to occur if (i) any "person" (as that term is
used in Sections 13 and 14(d)(2) of the Securities Exchange Act of 1934 (the
"Exchange Act")) other than William R.  Berkley or his "affiliates" (as that
term is defined in Rule 144 promulgated pursuant to the Securities Act of 1933
(the "Securities Act")) is or becomes the beneficial owner (as that term is
used in Section 13(d) of the Exchange Act), directly or indirectly, of 30% or
more of either the outstanding shares of Common Stock or the combined voting
power of the Company's then outstanding voting securities entitled to vote
generally, (ii) during any period of two consecutive years, individuals who at
the beginning of such period constitute the Board cease for any reason to
constitute at least a majority thereof, unless the election or the nomination
for election by the Company's shareholders of each new director was approved by
a vote of at least three-quarters of the directors then still in office who
were directors at the beginning of the period, or (iii) the Company undergoes a
liquidation or dissolution or a sale of all or substantially all of the assets
of the Company.  Any merger, consolidation or corporate reorganization in which
the owners of the combined voting power of the Company's then outstanding
securities entitled to vote generally prior to said combination, own 50% or
more of the resulting entity's outstanding securities entitled to vote
generally shall not, by itself, be considered a change in control.

                 3.  Termination of Employment.  (a) If the Optionee shall
cease to be employed by reason of Normal Termination, the Options shall remain
exercisable until the earlier of the Termination Date or the date that is three
months after the date of such Normal Termination to the extent the Options were
exercisable at the time of such Normal Termination.  For purposes of this
Agreement, the term "Normal Termination" shall mean termination of Optionee's
employment with the Company or a subsidiary thereof, as the case may be, (i)
because of retirement pursuant to the qualified retirement plan of the Company
or a parent or subsidiary thereof, as the case may be; (ii) on account of
Disability; (iii) with the written approval of the committee administering the
Plan in accordance therewith (the "Committee"); or (iv) by the Company or a
parent or subsidiary thereof, as the case may be, without Cause. For purposes
of the preceding sentence, (I) "Disability" shall mean disability as defined in
the Company's or a subsidiary's or parent's, as the case may be, long term
disability plan then in effect, or, in the absence of such plan, the complete
and permanent inability by reason of illness or accident to perform the duties
of the occupation at which the Optionee was employed when such disability
commenced or, if the Optionee was retired when such disability commenced, the
inability to engage in any substantial gainful activity, as determined by the
Committee based upon medical evidence acceptable to it, and (II) "Cause" shall
mean the Company or a parent or subsidiary thereof, as the case may be, having
cause to terminate an Optionee's employment under any existing employment
agreement between the Optionee and the Company or such parent or subsidiary or,
in the absence of such an employment agreement, upon (A) the determination by





                                       2
<PAGE>   3
the Committee that the Optionee has ceased to perform his duties to the Company
or a parent or subsidiary thereof, as the case may be (other than as a result
of his incapacity due to physical or mental illness or injury), which failure
amounts to an intentional and extended neglect of his duties to such party, (B)
the Committee's determination that the Optionee has engaged or is about to
engage in conduct materially injurious to the Company or a parent or subsidiary
thereof, or (C) the Optionee having been convicted of a felony.

                 (b)  If the Optionee shall die on or prior to the Termination
Date or within three months of Normal Termination, the executor or
administrator of the estate of the Optionee or the person or persons to whom
the Options shall have been validly transferred by the executor or
administrator pursuant to will or the laws of descent and distribution shall
have the right, until the earlier of the Termination Date or the date that is
12 months after the date of the Optionee's death, to exercise the Options to
the extent that the Options were exercisable at the date of death, subject to
any other limitation contained herein on the exercise of the Options in effect
on the date of exercise.

                 (c) If the Optionee terminates employment for reasons other
than death or Normal Termination, the Options, to the extent not exercised
prior to such termination, shall lapse and be cancelled; provided, however,
that a transfer of employment directly from the Company or a parent or
subsidiary thereof directly to another of any such entities shall not be deemed
a termination of employment for purposes of this Agreement.

                 (d)  Any provision of paragraphs 3(a), 3(b) or 3(c) hereof to
the contrary notwithstanding, the Options may not be exercised beyond the
Termination Date.

                 (e)      Whether employment has been or could have been
terminated for the purposes of this Agreement, and the reasons therefor, shall
be determined by the Committee, whose determination shall be final, binding and
conclusive.

                 (f)  After the expiration of any exercise period described in
either of paragraphs 3(a), 3(b) or 3(c) hereof, the Options shall terminate
together with all of the Optionee's rights hereunder, to the extent not
previously exercised.

                 4. Method of Exercising Option.  The Optionee may exercise any
or all of the Options by delivering to the Committee a written notice signed by
the Optionee stating the number of Options that the Optionee has elected to
exercise at that time and full payment of the purchase price of the shares to
be thereby purchased from the Company.  Payment of the purchase price of the
shares may be made (a) by certified or bank cashier's check payable to the
order of the Company, (b) by surrender or delivery to the Company of shares of
Stock having an aggregate fair market value equal to the exercise price, or (c)
in the discretion of the Committee, by surrender or delivery to the Company of,
(X) other property having a fair market value on the date of exercise equal to
the purchase price or (Y) a copy of irrevocable instructions to a





                                       3
<PAGE>   4
stockbroker to deliver promptly to the Company an amount of sale or loan
proceeds sufficient to pay the purchase price.

                 5.  Issuance of Shares.  As promptly as practical after
receipt of such written notification and full payment of such purchase price,
the Company shall issue or transfer to the Optionee the number of shares with
respect to which Options have been so exercised, and shall deliver to the
Optionee a certificate or certificates therefor, registered in the Optionee's
name.

                 6.  Optionee.   Whenever the word "Optionee" is used in any
provision of this Agreement under circumstances where the provision should
logically be construed to apply to the executors, the administrators, or the
person or persons to whom the Options may be transferred by will or by the laws
of descent and distribution, the word "Optionee" shall be deemed to include
such person or persons.

                 7.  Non-Transferability.  The Options are not transferable by
the Optionee otherwise than by will or the laws of descent and distribution and
are exercisable during the Optionee's lifetime only by him.  No assignment or
transfer of the Options, or of the rights represented thereby, whether
voluntary or involuntary, by operation of law or otherwise (except by will or
the laws of descent and distribution), shall vest in the assignee or transferee
any interest or right herein whatsoever, but immediately upon such assignment
or transfer the Options shall terminate and become of no further effect.

                 8.  Rights as Stockholder.  The Optionee or a transferee of
the Options shall have no rights as a stockholder with respect to any share
covered by the Options until he shall have become the holder of record of such
share, and no adjustment shall be made for dividends or distributions or other
rights in respect of such share for which the record date is prior to the date
upon which he shall become the holder of record thereof.

                 9. Recapitalizations, Reorganizations, etc.  (a) The existence
of the Options shall not affect in any way the right or power of the Company or
its stockholders to make or authorize any or all adjustments,
recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or
any issue of stock or of options, warrants or rights to purchase stock or of
bonds, debentures, preferred or prior preference stocks ahead of or affecting
the Stock or the rights thereof or convertible into or exchangeable for Stock,
or the dissolution or liquidation of the Company, or any sale or transfer of
all or any part of its assets or business, or any other corporate act or
proceeding, whether of a similar character or otherwise.

                 (b)  The shares with respect to which the Options are granted
are shares of Stock of the Company as presently constituted, but if, and
whenever, prior to the delivery by the Company of all of the shares of the
Stock with respect to which the Options are granted, the Company shall effect a
subdivision or consolidation of shares of the Stock outstanding, without





                                       4
<PAGE>   5
receiving compensation therefor in money, services or property, the number and
price of shares remaining under the Options shall be appropriately adjusted.
Such adjustment shall be made by the Committee, whose determination as to what
adjustment shall be made, and the extent thereof, shall be final, binding and
conclusive.  Any such adjustment may provide for the elimination of any
fractional share which might otherwise become subject to the Options.

                 (c)  In the event of any change in the outstanding shares of
Stock by reason of any recapitalization, merger, consolidation, spin-off,
combination or exchange of shares or other corporate change, or any
distributions to common shareholders other than cash dividends, the Committee
shall make such substitution or adjustment, if any, as it deems to be
equitable, as to the number or kind or shares of Stock or other securities
covered by the Options and the option price thereof.

                 (d)  Except as expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into or exchangeable
for shares of stock of any class, for cash or property, or for labor or
services, either upon direct sale or upon the exercise of options, rights or
warrants to subscribe therefor, or to purchase the same, or upon conversion of
shares or obligations of the Company convertible into such shares or other
securities, shall not affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Stock subject to the Options.

                 10.  Compliance with Law.  (a)  Notwithstanding any of the
provisions hereof, the Optionee hereby agrees that he will not exercise the
Options, and that the Company will not be obligated to issue or transfer any
shares to the Optionee hereunder, if the exercise hereof or the issuance or
transfer of such shares shall constitute a violation by the Optionee or the
Company of any provisions of any law or regulation of any governmental
authority.  Any determination in this connection by the Committee shall be
final, binding and conclusive.  The Company shall in no event be obliged to
register any securities pursuant to the Securities Act of 1933 (as now in
effect or as hereafter amended) or to take any other affirmative action in
order to cause the exercise of the Options or the issuance or transfer of
shares pursuant thereto to comply with any law or regulation of any
governmental authority.

                 (b)  Upon demand by the Committee, the Optionee shall deliver
to the Committee at the time of any exercise of an Option hereunder a written
representation that the shares to be acquired upon such exercise are to be
acquired for investment and not for resale or with a view to the distribution
thereof.  Upon such demand, delivery of such representation prior to the
delivery of any shares issued upon exercise of an Option shall be a condition
precedent to the right of the Optionee or such other person to purchase any
shares.  In the event certificates for Stock are delivered under this Agreement
with respect to which such investment representation has been obtained, the
Committee may cause a legend or legends to be placed on such certificates to
make appropriate reference to such representation and to restrict transfer in
the absence of compliance with applicable federal or state securities laws.

                 11.  Notice.  Every notice or other communication relating to
this Agreement shall be in writing, and shall be mailed to or delivered to the
party for whom it is intended at such address as may from time to time be
designated by it in a notice mailed or delivered to the other party as herein
provided; provided that, unless and until some other address be so designated,
all notices or communications by the Optionee to the Company shall be mailed or
delivered to the Company at its principal executive office, and all notices or
communications by the Company to the Optionee may be given to the Optionee
personally or may be mailed to him at the Optionee's last known address as
reflected in the Company's records.

                 12.  Disposition of Stock.  The Optionee agrees to notify the
Company in writing, within 30 days of any disposition (whether by sale,
exchange, gift or otherwise) of shares of Stock purchased under this Option,
within two years from the date of the granting of the Option or within one year
of the transfer of such shares of Stock to the Optionee.

                 13.      Binding Effect.  Subject to Section 7 hereof, this
Agreement shall be binding upon the heirs, executors, administrators and
successors of the parties hereto.

                 14.      Governing Law.  This Agreement shall be construed and
interpreted in accordance with the laws of the State of Texas without reference
to the principles of conflicts of law thereof.

                 15.      Plan.  The terms and provisions of the Plan are
incorporated herein by reference.  In the event of a conflict or inconsistency
between discretionary terms and provisions of the Plan and the express
provisions of this Agreement, this Agreement shall govern and control.  In all
other instances of conflicts or inconsistencies or omissions, the terms and
provisions of the Plan shall govern and control.

                 16.      Restrictions in Certificate of Incorporation.  The
Options and any shares acquired upon exercise thereof may be subject to certain
restrictions on transfer contained in the Certificate of Incorporation of the
Company, a copy of which may be obtained by the Optionee upon written request
to the Secretary of the Company.
