                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  BASIS OF PRESENTATION

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

For purposes of comparability, the consolidated financial information of Pioneer
Americas, Inc. ("Pioneer" or the "Predecessor Company") has been included. The
consolidated balance sheet of the Predecessor Company at December 31, 1994
represents the balance sheet included in the audited historical financial
information of the Predecessor Company that appeared in the Form 8-K and Form
8-K/A of Pioneer Companies, Inc. ("PCI" or the "Company") dated April 20,1995
reporting its acquisition of all of the outstanding stock and other common
equity interests of the Predecessor Company.

The financial information for the periods presented for the Predecessor Company
has been prepared by the Company from the accounting records of the Predecessor
Company applying the same methodology and assumptions as were applied in the
preparation of the audited historical financial information of the Predecessor
Company that appeared in the Company's Form 8-K and Form 8-K/A dated April 20,
1995.

Share and per share information has been retroactively restated to reflect the
one-for-four reverse stock split of the Company's Class A and Class B Common
Stock, effective April 27, 1995.  Income (loss) per common share is computed
using the weighted average number of Class A and Class B common shares
outstanding during the period.

BASIS OF PRESENTATION EFFECTIVE APRIL 20, 1995

On March 31, 1995, the registrant's shareholders approved a change in name from
GEV Corporation to Pioneer Companies, Inc.  This name change was effected in
conjunction with  the following acquisition:

On April 20, 1995, pursuant to a Stock Purchase Agreement, dated as of March 24,
1995  (the "Acquisition Agreement"), by and among PCI, Pioneer Americas
Acquisition Corp., a newly-formed wholly-owned subsidiary of PCI ("PAAC") , and
the holders of the outstanding common stock and other common equity interests
(the "Sellers") of the Predecessor Company, PAAC 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 pursuant to a Contingent Payment Agreement
among PCI, PAAC and the Sellers ("Contingent Payment Agreement")  after the
closing based upon earnings or proceeds attributable to certain of Pioneer's
direct and indirect real estate holdings ("Contingent Payment Properties") which
are not necessary for Pioneer's business.  In addition, as further consideration
for the Acquisition, PAAC paid approximately  $45.5 million to retire all
outstanding indebtedness (net of available cash) of the Predecessor Company and
$5.0 million to redeem the Predecessor Company's outstanding preferred stock for
a total purchase price of $166.4 million including $2.4 million of expenses.

1.    BASIS OF PRESENTATION (CONTINUED)

In connection with the consummation of the Acquisition, (i) PAAC issued and sold
$135 million aggregate principal amount of 13 3/8% Senior Notes (the "Initial
Offering" or "Senior Notes"), (ii) PCI issued and sold the Seller Notes in
exchange for certain of the outstanding shares of Pioneer, which PCI contributed
to PAAC, (iii) the Company issued and sold to Interlaken Investment Partners,
L.P., a Delaware limited partnership (the "Interlaken Partnership"), 2,840,909
shares of 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 PAAC, (iv) PCI issued and sold to certain employees and directors
of the Predecessor Company (collectively, the "Management Investors"), 1,136,363
shares of Class A Common Stock of PCI for an aggregate purchase price of $6
million (the "Management Purchase"), the proceeds of which were contributed to
PAAC, and (v) Pioneer and its subsidiaries entered into a new bank revolving
credit facility (the "Bank Credit Facility")  providing for borrowings of up to
$30 million.  The net proceeds of the Initial Offering, 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 Predecessor Company indebtedness, to
redeem the Predecessor Company's outstanding preferred stock and to pay certain
transaction costs associated with the Acquisition.

The Acquisition has been accounted for by the purchase method of accounting.
The excess of the purchase price over the estimated fair value of the net assets
acquired of approximately $111 million will be amortized on a straight line
basis over periods of up to 25 years.  The purchase price allocation is based on
preliminary estimates of the fair value of the net assets acquired and
liabilities assumed and is subject to adjustment as additional information
becomes available.  Such information relates principally to appraisals of plant,
property and equipment which management expects to obtain as soon as is
practical.

The following pro forma financial data presents the consolidated financial
results of operations as if the Acquisition, the Initial Offering, the
Interlaken Partnership Purchase, the Management Purchase and the borrowing under
the Bank Credit Facility had occurred at the beginning of the periods presented
and does not purport to be indicative of either future results of operations or
results that would have occurred had the Acquisition actually been made as of
such dates.

The pro forma combined statements of operations reflect the inclusion of the
Predecessor Company's results of operations for the period from January 1, 1995
through April 20, 1995 and for the six months ended June 30, 1994 as applicable,
adjusted for: depreciation and amortization on property, plant and equipment
valuation increases of $254,630 and $416,667, excess cost over fair value of net
assets acquired and financing costs of $1.5 million and $2.5 million; interest
expense on financing in connection with the Acquisition of $5.8 million and $9.4
million; adjustment of the income tax provision of $1.7 million and $1.7
million; and elimination of historical interest expense of $1.7 million and
$3.3 million, amortization of excess cost over fair value of net assets acquired
and amortization of organization costs of $1.2 million and $1.2 million and
equity income from certain real estate investments of $0.2 million and $0.0
million. The results of operations for the six months ended June 30, 1995
include the effects of an increase to cost of sales due to a step up in value of
inventory in connection with the Acquisition of $1.7 million ($0.12 per share.)
The June 30, 1994 pro forma information also reflects the elimination of the
expense related to special appreciation rights granted to a subordinated debt
holder of $968,000 and contingent bank fees of $1.4 million.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

Periods prior to April 1, 1995 include the accounts of PCI (formerly GEV
Corporation).  The 1995 financial statements for periods beginning April
1, 1995 include the accounts and operations of PCI since April 1, 1995 and its
wholly owned subsidiaries, PAAC and Pioneer, since April 20, 1995.  All
intercompany accounts and transactions have been eliminated.

INVENTORIES

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 results of operations for the three months and six months ended June
30, 1995 include the effects of an increase to cost of sales due to a step up in
value of inventory in connection with the Acquisition of $1.7 million ($0.13 per
share and $0.16 per share, respectively).


PROPERTY, PLANT AND EQUIPMENT

Depreciation for financial reporting purposes is computed under the straight-
line method over the estimated remaining useful lives of the assets.

OTHER ASSETS

Other assets include amounts for organization costs and deferred financing costs
which are being amortized on a straight-line basis over their estimated useful
lives.  Deferred financing costs are being amortized on a straight-line basis
over the term of the related debt. Amortization expense for other assets was
approximately $266,000 for the three months and six months ended June 30, 1995.

EXCESS COST OVER THE FAIR VALUE OF NET ASSETS ACQUIRED

Excess cost over the fair value of net assets acquired of approximately $111
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 quarterly and if this review indicates that such excess cost will not
be recoverable, as determined based on the undiscounted cash flows of the entity
acquired over the remaining amortization period, the Company's carrying value of
the excess cost over the fair value of net assets acquired will be reduced by
the estimated shortfall of cash flows.  Amortization expense for excess cost
over the fair value of net assets acquired was approximately $802,000 for the
three months and six months ended June 30, 1995.

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.  Sales are primarily to customers in the western and southeastern
regions of the United States.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

ENVIRONMENTAL EXPENDITURES

Environment-related restoration and remediation costs are recorded as
liabilities and expensed when site restoration and environmental remediation and
clean-up obligations are either known or considered probable and the related
costs can be reasonably estimated. Other environmental expenditures, principally
maintenance or preventative in nature, are recorded when expended and are
expensed or capitalized as appropriate.

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 and its subsidiaries file a consolidated tax return. The Company has
entered into a tax sharing agreement with PAAC whereby PAAC will make tax
sharing payments to PCI with respect to federal cash income taxes reflecting the
consolidated cash tax liability of PCI.  State income taxes are included in
income taxes payable.

FUTURE TAX EFFECTS

Future tax effects are computed under the provisions of SFAS No. 109
("Accounting for Income Taxes") and result from temporary differences in the
recognition of expenses for financial reporting and tax purposes.  Temporary
differences include differences in methods of computing depreciation for
financial statement and tax purposes and differences in the financial statement
basis and tax basis of assets and liabilities acquired, primarily excess cost
over fair value of net assets acquired.

3. INVENTORIES

Inventories consist of the following:

Exchanges payable result from exchange product transactions which are entered
into between the Company and other producers that manufacture homogeneous
products, whereby other producers ship product on behalf of the Company to its
customers. These exchanges, which are recorded as payables, generally are
settled by the Company's shipment of product to such producers' customers.

5.  PENSION AND OTHER EMPLOYEE BENEFITS

Annual pension costs and liabilities for the Company under its two defined-
benefit plans are determined by actuaries using various methods and assumptions.
For purposes of determining annual expenses and funding contributions, the
following assumptions were used for the year ended December 31:

Approximately $49,000 was contributed to defined-contribution savings plans
for the three months and six months ended June 30, 1995.

In addition to providing pension benefits, one of the Company's subsidiaries
provides certain health care and life insurance benefits for retired employees.
Substantially all of the subsidiary's employees may become eligible for those
benefits if they reach normal retirement age while working for the subsidiary.

The following table presents the plan's funded status reconciled with amounts
recognized in the Company's balance sheet:

</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 10.5%  for 1995 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
postretirement benefit obligation as of December 31, 1994 by $633,000 and the
aggregate of the service and interest cost components of the net periodic
postretirement benefit cost for 1994 by $82,000.

The weighted-average discount rate used in determining the accumulated
postretirement benefit obligation was 7.5% at December 31, 1994.

6.  BANK CREDIT FACILITY

In April 1995, Pioneer entered into a credit agreement, which provides for a
three year Bank Credit Facility with Bank of America, Illinois ("BAI") due April
20, 1998.  Pioneer may borrow up to $30.0 million, subject to certain borrowing
base limitations.  At June 30, 1995, approximately $3.0 million was owed under
the Bank Credit Facility.  The revolving loan bears interest at a rate equal to,
at Pioneer's option, (i) the reference rate set by BAI or (ii) the LIBOR Base
Rate.  At June 30, 1995, Pioneer utilized the reference rate set by BAI of 9%.
The Bank Credit Facility requires Pioneer 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 Pioneer's inventory, accounts receivable and  certain other assets.  Up to $6
million of the Borrowing Base, as defined in the Bank Credit Facility, can be
utilized for letters of credit.  The Borrowing Base at June 30, 1995 was
approximately $22 million.  After consideration of the outstanding letters of
credit of approximately $2.7 million and the use of the revolver of $3.0
million, the unused availability of the Borrowing Base was approximately $16.3
million at June 30, 1995.

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

7.  13 3/8% SENIOR NOTES DUE 2005

In April 1995, PAAC issued and sold $135 million of Senior Notes. Interest is
payable on April 1 and October 1 of each year. The Senior Notes are senior
secured obligations of PAAC, ranking senior in right of payment to all
subordinated indebtedness of PAAC (including the Seller Notes) and pari passu in
right of payment with each other and with all existing and future senior
indebtedness, including indebtedness under the Bank Credit Facility.

PAAC has agreed to file a Registration Statement with the Securities and
Exchange Commission pursuant to which it will propose to offer to exchange (the
"Exchange Offer") up to $135 million aggregate principal amount of 13 3/8% 
Senior Notes due 2005 (the "Exchange Notes") for up to $135 million aggregate
principal amount of its outstanding Senior Notes. PAAC expects to secure the
Senior Notes with first mortgage liens on certain Pioneer manufacturing
facilities prior to the effectiveness of such Registration Statement. If the
Registration Statement becomes effective and PAAC proceeds with the Exchange
Offer, the terms of the Exchange Notes and Senior Notes will be substantially
identical, except that the Exchange Notes will be freely transferable subject to
certain provisions. If the Registration Statement is not declared effective by
August 13, 1995 or the Exchange Offer is not consummated by September 12, 1995
(each, a "Registration Default"), the interest rate borne by the Senior Notes
will be increased by 25 basis points per annum for the 90-day period following
such Registration Default. Such interest rate will increase by an additional 25
basis points per annum at the beginning of each subsequent 90-day period, up to
a maximum aggregate increase of 150 basis points per annum. PAAC does not expect
that the Registration Statement will be declared effective by August 13, 1995 or
that the Exchange Offer will be consummated by September 12, 1995. If,
subsequently, such Registration Default is cured, the interest rate borne by the
Senior Notes will be reduced by the amount of any such increase.


The Senior Notes are redeemable at PAAC's option on and after April 1, 2000.  In
addition, PAAC may also redeem at its option at any time prior to April 1, 1998
up to $35.0 million of the Senior Notes at 113% of the principal amount thereof
with funds raised in a public offering of common stock of PAAC or of common
stock of PCI to the extent such proceeds are contributed to PAAC.  Upon a change
of control, as defined in the Senior Notes' indenture,  PAAC will be required to
offer to repurchase the Senior Notes at a purchase price equal to 101%.

The Senior Notes contain restrictive covenants that, among other things and
under certain conditions, limit the ability of PAAC to incur additional
indebtedness, to issue preferred stock, to acquire or dispose of assets or
operations, to make capital expenditures and to pay dividends or redeem shares
of stock. 

8.  SELLER NOTES

At the Closing of the Acquisition, the Company delivered to the Sellers, Seller
Notes in the aggregate principal amount of $11.5 million, after adjustments
resulting from terms and conditions defined in the Acquisition Agreement.
Interest on the Seller Notes is payable at a rate of 8% per annum on a quarterly
basis. The principal is payable in five equal annual installments commencing on
April 20, 2001.

8.  SELLER NOTES (CONTINUED)

The Seller Notes contain restrictive covenants that, among other things and
under certain conditions, limit the ability of the Company to incur additional
indebtedness, to issue preferred stock, to acquire or dispose of assets or
operations, to make capital expenditures and to pay dividends or redeem shares
of stock.

9.  COMMITMENTS AND CONTINGENCIES

LETTERS OF CREDIT

At June 30, 1995, the Company had letters of credit and performance bonds
outstanding of approximately $2,713,000 and $6,665,000, respectively.  These
letters of credit and performance bonds were issued for the benefit of customers
under sales agreements securing delivery of products sold and as guaranties for
payment of certain utility and regulatory liabilities.  The letters of credit
expire at various dates during 1995 and 1996.

PURCHASE COMMITMENTS

One of the Company's subsidiaries has committed to purchase electrical power and
transmission services for its chlor alkali plants through September 30, 2017. At
the current base price, allocated capacity, and allocated energy per the
contract terms, this commitment would approximate $5,020,000 for the last six
months of 1995; $2,546,000 for each of the years 1996 through 2000; $1,261,000
for each of the years 2001 through 2008; and $1,017,000 for each of the years
2009 through 2017. The allocated capacity is subject to adjustment for other
priority users. The subsidiary purchased approximately $3,604,000 in electrical
power and transmission services for the three months and six months ended June
30, 1995.

In addition, the subsidiary has committed to purchase salt used in the
production process under contracts which continue through December 31, 2003.
Based on the contract terms, a minimum of  278,000 tons of salt are to be
purchased in the last six months of 1995; 442,000 tons in 1996 and 1997; 279,000
tons in 1998; and 225,000 tons in years 1999 through 2003. The future minimum
salt commitments are as follows (in thousands):

The subsidiary purchased approximately $1.7 million of salt for the three months
and six months ended June 30, 1995.  Substantially all of the salt has been used
in production during the three months and six months ended June 30, 1995 and
therefore has been included in cost of sales.

OPERATING LEASES

The Company and its subsidiaries lease certain of their 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 June 30, 1995 are (in thousands):

</TABLE>

Lease expense charged to operations for the three months and six months ended
June 30, 1995 was approximately $1.4 million.

SALES COMMITMENTS

Pioneer has a sales contract with a customer which requires Pioneer to sell
and the customer to purchase amounts of chlorine and caustic soda of not less
than the percentage of the customer's use of chlorine and caustic soda supplied
by Pioneer in the 12-month period ended July 31, 1987 (base period). Pioneer
supplied approximately 91,000 tons of chlorine and 21,000 tons of caustic soda
in the base period. The contract, which expires on December 31, 1997, states
that the sales price will not be less than Pioneer's standard cost as calculated
based on 1987 amounts and adjusted thereafter for price changes for raw
materials and changes in other costs as reflected in the producer price index.

LITIGATION

Pioneer settled litigation with an insurance company in December 1992 relating
to claims resulting from a chlorine release in 1991. In accordance with the
settlement, the insurance company paid Pioneer $2.1 million relating to claims
paid by Pioneer prior to November 1, 1992 and agreed to pay Pioneer (a) upon
proof of same, $100,000 relative to claims and expenses incurred after July 31,
1992 but prior to November 1, 1992 and (b) all claims after November 1, 1992
until an aggregate total of $3.8 million had been paid.  As of April 20, 1995, a
total of approximately $3.8 million in claims had been paid.  It is the opinion
of management, based on advice of counsel, that the ultimate resolution of this
contingency, to the extent not previously provided for, will not have a material
effect on the consolidated financial statements of the Company.

During 1993, one of Pioneer's subsidiaries, Imperial West, was awarded $1.38
million as the result of a breach of contract claim it asserted against the
lessor of one of Imperial West's plants. The judgment has been appealed and the
consolidated financial statements do not include any receivable for the award
that could result from the judgment. The lessor subsequently filed suit alleging
that Imperial West is required to remediate alleged contamination prior to the
termination of the lease in July 1995. The parties have agreed to settle that
action under terms which will require (i) Imperial West to pay the lessor
$900,000 upon the termination of the lease, and (ii) the lessor to transfer
title to the property to Imperial West. In addition, Imperial West has agreed to
indemnify the lessor against any future environmental liability with respect to
the property. The settlement will not affect the appeal pending with respect to
the breach of contract judgment. Certain insurers have agreed to pay a portion
of Imperial West's defense costs in connection with the subsequent lawsuit by
the lessor. Imperial West is pursuing a claim for contribution from the insurers
with respect to the cost incurred in settling the action.

9.  COMMITMENTS AND CONTINGENCIES (CONTINUED)

In October 1994, the trustee in the bankruptcy of a company which was a customer
of Pioneer filed suit against Pioneer, seeking the recovery of up to $2.2
million in payments made to Pioneer on a basis which the trustee alleges were
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 substantially below the amount claimed, and Pioneer is vigorously contesting
the action. The Company has established a reserve consistent with its estimate 
of its liability related to such transactions.

The Company and its subsidiaries are parties to other legal proceedings and
potential claims arising in the ordinary course of their businesses. In the
opinion of management, the Company and its subsidiaries have 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.

10.  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

</TABLE>

At June 30, 1995, PCI had available to it on a consolidated tax return basis
approximately $77 million of net operating loss carryforward ("NOL") for income
tax reporting purposes (expiring 2003 to 2010). The NOL is available for offset
against future taxable income if generated during the carryforward period.

The Internal Revenue Code limits the amount of a corporation's NOL's that may be
used each year to offset future income after an "ownership change" (as defined).
PCI does not believe that either the reorganization resulting from certain
previous Chapter 11 proceedings or the Acquisition resulted in an ownership
change.

Upon adoption of Statement of Financial Accounting Standard No. 109, "Accounting
for Income Taxes," PCI established a deferred tax asset based upon the future
utilization of the net operating loss carryforward.  However, since PCI had no
operating subsidiaries at December 31, 1994 with which to generate taxable
income, a 100% valuation reserve was recorded against this asset.  Due to the
reorganization, any future utilization of this NOL by PCI will be recognized as
an increase to additional paid-in capital. Approximately $13.6 million was
recognized as an increase to additional paid-in capital at April 20, 1995.

11.   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. The Company believes that it is in substantial compliance with existing
governmental regulations.

In connection with the October, 1988, acquisition of the chlor alkali business
by the Predecessor Company, ICI Delaware Holdings, Inc. ("ICI") and ICI
Americas, Inc. ("ICI Americas") (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 Acquisition of the Predecessor Company by PAAC, the ZENECA Indemnity
will terminate on April 20, 1999, four years after consummation of the
Acquisition. 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 Acquisition Agreement, the Sellers have agreed to indemnify PCI, PAAC and
their affiliates 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 the Contingent Payment Properties
("Sellers' Indemnity").  Amounts payable pursuant to the Sellers' Indemnity will
generally be payable as follows:  (i) out of certain reserves established on
Pioneer'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 after the Closing Date. The Company 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.
The Company and the Sellers have agreed that they will cooperate in matters
relating to the ZENECA Indemnity.

11.   OTHER LONG-TERM LIABILITIES - ENVIRONMENTAL (CONTINUED)

Liabilities related to environmental matters are recorded when site restoration
and environmental remediation and clean-up obligations are either known or
considered probable and are reasonably determinable. 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, and capital expenditures for environmental related
matters at existing facilities were immaterial for the three months and six
months ended June 30, 1995. 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 Pioneer for chlor alkali-related remediation of
the Henderson and St. Gabriel facilities. The recorded accrual includes certain
amounts related to anticipated closure and post-closure actions that may be
required when operation of the present chlor alkali plants ceases. However, a
complete analysis and study have 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. Other assets include an account
receivable of the same amount from the ZENECA Companies. Certain other
environmental matters exist for which the Company has not determined the
specific strategy for or cost of remediation. It is possible that additional
costs, depending on the final choice of remediation strategies, may be incurred
in the future. As additional information becomes available, changes in the
estimates of liabilities will be recorded. If such costs are incurred,
additional annual operating and maintenance costs may also be required. 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 BII properties.
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 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.

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

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

This item will discuss and analyze the financial condition of the Company at
June 30, 1995 and the results of operations of the Company for the three months
and six months ended June 30, 1995 and the Predecessor Company for the 
three months and six months ended June 30, 1994. For comparative purposes the
Company's results of operations for the three months ended June 30, 1995 include
the Predecessor Company's operating results from April 1, 1995 through April 20,
1995 and the Company's operating results for the six months ended June 30, 1995
include the Predecessor Company's operating results from January 1, 1995 through
April 20, 1995. The Predecessor Company's operating results for both periods
exclude $1.0 million of transaction costs related to the Acquisition. The
Company believes that this provides a meaningful basis for comparison.

The following table sets forth certain operating data of the Company for the
periods indicated as adjusted for comparative purposes as discussed above.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1995 COMPARED TO SIX MONTHS ENDED JUNE 30, 1994

REVENUES

Revenues increased by $20.9 million or 28% to $94.3 million for the six months
ended June 30, 1995 from $73.4 million for the six months ended June 30, 1994.
This increase was primarily due to a $16.1 million increase in chlor-alkali
sales, a result of industry-wide strengthening of electrochemical unit ("ECU")
prices. The six month average ECU price at June 30, 1995 increased 47% over the
same period in 1994.  In addition, in May 1994, the Predecessor Company acquired
an entity which contributed approximately $5.1 million in revenues during the
first six months of 1995 compared to $1.8 million in 1994.

COST OF SALES

Cost of sales increased by $0.6 million or 1% to $64.0 million for the six
months ended June 30, 1995 from $63.4 million for the six months ended June 30,
1994. This increase represented primarily the $1.0 million impact of an
acquisition by the Predecessor Company in May 1994, annual performance raises
and associated benefits costs of $2.5 million, higher operating and maintenance
material costs of $1.5 million due to an increase in non-critical scheduled
maintenance, net of capitalized maintenance costs and additional miscellaneous
items. Additionally, $1.7 million was charged to cost of sales due to the
acquisition related inventory step up. These increases were partially offset by
$6.3 million of lower raw material costs, purchases and exchange activity.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE

Selling, general and administrative expense increased by $3.0 million or 31% to
$12.8 million for the six months ended June 30, 1995 from $9.8 million for the
six months ended June 30, 1994. This increase was primarily the result of a
$1.3 million impact of an acquisition by the Predecessor Company in May 1994,
$0.4 million of increased outside services, and $0.8 million of increased
amortization as a result of the Acquisition.

INTEREST

Interest expense increased by $2.2 million or 67% to $5.5 million for the six
months ended June 30, 1995 from $3.3 million for the six months ended June 30,
1994. This increase was a result of debt incurred in connection with the 
Acquisition.

INCOME BEFORE TAXES AND EXTRAORDINARY ITEM

As a result of the above, net income before taxes and extraordinary expense
increased $16.6 million to $13.2 million of income for the six months ended June
30, 1995 from a $3.4 million loss for the six months ended June 30, 1994.

EXTRAORDINARY ITEM

An extraordinary expense of $3.4 million net of income taxes of $2.1 million for
the six months ended June 30, 1995 was due to costs incurred, and previously
capitalized costs written off, pertaining to debt refinanced by the Predecessor 
Company in the 1995 period prior to the Acquisition.

THREE MONTHS ENDED JUNE 30, 1995 COMPARED TO THREE MONTHS ENDED JUNE 30, 1994

REVENUES

Revenues increased by $7.3 million or 19% to $46.4 million for the three months
ended June 30, 1995 from $39.1 million for the three months ended June 30, 1994.
This increase was primarily due to a $5.7 million increase in chlor-alkali
sales, a result of industry-wide strengthening of ECU prices.  The three month
average ECU price at June 30, 1995 increased 44% over the same period in 1994.
In addition, in May 1994, the Predecessor Company acquired an entity which
contributed approximately $3.2 million in revenues during 1995 compared to $1.8
million in 1994.

COST OF SALES

Cost of sales decreased by $0.2 million to $33.3 million for the three months
ended June 30, 1995 from $33.5 million for the three months ended June 30, 1994.
This decrease was primarily a result of $4.2 million of lower raw material
costs, purchases and exchange activity, partially offset by the $1.0 million
impact of an acquisition by the Predecessor Company in May 1994, higher salaries
and fringe benefits of $1.5 million and additional miscellaneous items.
Additionally, $1.7 million was charged to cost of sales due to the Acquisition
related inventory step up.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE

Selling, general and administrative expense increased by $2.1 million or 40%  to
$7.4 million for the three months ended June 30, 1995 from $5.3 million for the
three months ended June 30, 1994. This increase was primarily the result of a
$0.5 million impact of an acquisition by the Predecessor Company in May 1994,
$0.7 million of increased outside services, and $0.3 million of increased
amortization as a result of the Acquisition.

INTEREST

Interest expense increased $2.4 million or 141% to $4.1 million for the three
months ended June 30, 1995 from $1.7 million for the three months ended June 30,
1994. This increase was a result of debt due to the Acquisition.

INCOME BEFORE TAXES AND EXTRAORDINARY ITEM

As a result of the above, net income before taxes and extraordinary expense
increased $3.0 million to $2.0 million for the three months ended June 30, 1995
from a $1.0 million loss for the three months ended June 30, 1994.

LIQUIDITY AND CAPITAL RESOURCES

A subsidiary of the Company has entered into a Bank Credit Facility, which
provides for borrowings of up to $30.0 million subject to borrowing base
limitations that relate to the level of accounts receivable and inventory of the
Company's subsidiaries. The Bank Credit Facility is secured by the accounts
receivable and inventory of the Company's subsidiaries and certain other
collateral. It has a term of three years and bears interest at a rate equal to
at the Company's option (i) the reference rate set by the Bank or (ii) the LIBOR
Base Rate.


                                    Page 25
<PAGE>
 
The Company estimates that cash flow from current levels of operations, together
with the availability under the Bank Credit Facility, will be adequate to make
required payments of principal and interest on the outstanding indebtedness as
well as to fund capital expenditures.

The Company incurred $3.3 million of capital expenditures for the three months
and six months ended June 30, 1995, and anticipates capital expenditures for
1995 to be approximately $12 million, including approximately $4.5 million for
environmental compliance matters.

ENVIRONMENTAL REGULATION

Liabilities are recorded when site restoration and environmental remediation and
clean-up obligations are either known or considered probable and are reasonably
determinable. 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

existing facilities were immaterial for the three months  and six months ended
June 30, 1995.  Future environmental-related capital expenditures will depend

          Section 103.   Compliance Certificates and Opinions.
                         ------------------------------------ 

          Upon any application or request by the Company or any Subsidiary
Guarantor to the Trustee to take any action under any provision of this
Indenture, the Company, any Subsidiary Guarantor and any other obligor on the
Securities shall furnish to the Trustee an Officers' Certificate stating that
all conditions precedent, if any, provided for in this Indenture (including any
covenants compliance with which constitutes a condition precedent) relating to
the proposed action have been complied with, an Opinion of Counsel stating that
in the opinion of such counsel all such conditions precedent, if any, have been

                                    - 27 -
<PAGE>
 
complied with, except that, in the case of any such application or request as to
which the furnishing of such documents, certificates and/or opinions is
specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

          Every certificate or Opinion of Counsel with respect to compliance
with a condition or covenant provided for in this Indenture shall include:

          (a) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

          (b) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinion contained in such
     certificate or opinion are based;

          (c) a statement that, in the opinion of each such individual, he has
     made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (d) a statement as to whether, in the opinion of each such individual,
     such condition or covenant has been complied with.

          Section 104.   Form of Documents Delivered to Trustee.
                         -------------------------------------- 

          In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer of the Company, any
Subsidiary Guarantor or other obligor of the Securities may be based, insofar as
it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous.  Any such certificate or opinion
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company, any

                                    - 28 -
<PAGE>
 
Subsidiary Guarantor or other obligor of the Securities stating that the
information with respect to such factual matters is in the possession of the
Company, any Subsidiary Guarantor or other obligor of the Securities, unless
such counsel knows that the certificate or opinion or representations with
respect to such matters are erroneous.  Opinions of Counsel required to be
delivered to the Trustee may have qualifications customary for opinions of the
type required and counsel delivering such Opinions of Counsel may rely on
certificates of the Company or government or other officials customary for
opinions of the type required, including certificates certifying as to matters
of fact, including that various financial covenants have been complied with.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          Section 105.   Acts of Holders.
                         --------------- 

          (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture, if made in the manner provided in this Section.  The fact and date of
the execution by any Person of any such instrument or writing or the authority
of the Person executing the same, may also be proved in any other manner which
the Trustee deems sufficient in accordance with such reasonable rules as the
Trustee may determine.

          (b) The ownership of Securities shall be proved by the Security
Register.

          (c) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind every future
Holder of the same Security or the Holder of every Security issued upon the
transfer thereof or in exchange therefor or in lieu thereof, in respect of
anything done, suffered or omitted to be done by the Trustee, any Paying Agent
or the Company or any Subsidiary Guarantor in reliance

                                    - 29 -
<PAGE>
 
thereon, whether or not notation of such action is made upon such Security.

          (d) If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to a Board Resolution, fix in advance a record
date for the determination of such Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so.  Notwithstanding Trust Indenture Act
Section 316(c), any such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not more than 30 days
prior to the first solicitation of Holders generally in connection therewith and
no later than the date such solicitation is completed.

          In the absence of any such record date fixed by the Company,
regardless as to whether a solicitation of the Holders is occurring on behalf of
the Company or any Holder, the Trustee may, at its option, fix in advance a
record date for the determination of such Holders entitled to give such request,
demand, authorization, direction, notice, consent, waiver or other Act, but the
Trustee shall have no obligation to do so.  Any such record date shall be a date
not more than 30 days prior to the first solicitation of Holders generally in
connection therewith and no later than a date such solicitation is completed.

          If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on
such record date shall be deemed to be Holders for purposes of determining
whether Holders of the requisite proportion of Securities then outstanding have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for this purpose the
Securities then Outstanding shall be computed as of such record date; provided
                                                                      --------
that no such request, demand, authorization, direction, notice, consent, waiver
or other Act by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date.

Subsidiary Guarantor.
-------------------- 

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or

                                    - 30 -

permitted by this Indenture to be made upon, given or furnished to, or filed
with:

          (a) the Trustee by any Holder or by the Company or any Subsidiary
     Guarantor or any other obligor of the Securities shall be sufficient for
     every purpose hereunder if in writing (including telecopy, with respect to
     the Company or any Subsidiary Guarantor only) and mailed, first-class
     postage prepaid, telecopied, hand delivered, or delivered by recognized
     overnight courier, to or with the Trustee at One State Street, New York,
     New York, 10004, Attention: Corporate Trust & Agency Administration,
     telecopy: 212-858-2952 or at any other address previously furnished in
     writing to the Holders, the Company, any Subsidiary Guarantor or any other
     obligor of the Securities by the Trustee; or

          (b) the Company or any Subsidiary Guarantor shall be sufficient for
     every purpose hereunder if in writing (including telecopy) and mailed,
     first-class postage prepaid, telecopied, hand delivered, or delivered by
     recognized overnight courier, to the Company or such Subsidiary Guarantor
     addressed to it at 4200 NationsBank Center, 700 Louisiana Street, Houston,
     TX 77002, Attention:  Vice President, General Counsel and Secretary,
     telecopy: 713-225-4426 or at any other address previously furnished in
     writing to the Trustee.

          Section 107.   Notice to Holders; Waiver.
                         ------------------------- 

          Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, or delivered by
recognized overnight courier, to each Holder affected by such event, at his
address as it appears in the Security Register, not later than the latest date,
and not earlier than the earliest date, prescribed for the giving of such
notice.  In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders.  Any notice when mailed to a Holder in the aforesaid manner shall
be conclusively deemed to have been received by such Holder whether or not
actually received by such Holder.  Where this Indenture provides for notice in
any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

                                    - 31 -
<PAGE>
 
          In case by reason of the suspension of regular mail service or by
reason of any other cause, it shall be impracticable to mail notice of any event
as required by any provision of this Indenture, then any method of giving such
notice as shall be reasonably satisfactory to the Trustee shall be deemed to be
a sufficient giving of such notice.

          Section 108.   Conflict with Trust Indenture Act.
                         --------------------------------- 

          If any provision hereof limits, qualifies or conflicts with any
provision of the Trust Indenture Act or another provision which is required or
deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, the provision or requirement of the Trust Indenture Act shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

          Section 109.   Effect of Headings and Table of Contents.
                         ----------------------------------------

                         ------------------- 

          In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

          Section 112.   Benefits of Indenture.
                         --------------------- 

          Nothing in this Indenture or in the Securities or the Guarantees,
express or implied, shall give to any Person (other than the parties hereto and

legal or equitable right, remedy or claim under this Indenture.

Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or of the Securities) payment of interest or
principal or premium, if any, need not be made on such date, but may be made on
the next succeeding Business Day with the same force and effect as if made on
the Interest Payment Date or Redemption Date, or at the Stated Maturity and no
interest shall accrue with respect to such payment for the period from and after

and release all such liability.  The waiver and release shall be part of the

          Section 201.   Forms Generally.
                         --------------- 

          The Securities, the Guarantees and the Trustee's certificate of
authentication shall be in substantially the forms set forth in this Article,
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by the Indenture and may have such letters, numbers

          Section 204.  Form of Reverse of Securities.
                        ------------------------------


           (a) The form of the reverse of the Securities shall be substantially
as follows:

          This Security is one of a duly authorized issue of Securities of the
Company designated as its 13 3/8% Senior Notes due 2005 (herein called the
"Securities"), limited (except as otherwise provided in the Indenture referred
to below) in aggregate principal amount to $135,000,000, which may be issued
under an indenture (herein called the "Indenture") dated as of April 1, 1995,
among the Company, the Subsidiary Guarantors and IBJ Schroder Bank & Trust
Company, as trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties, obligations and immunities thereunder of
the Company, the Subsidiary Guarantors, the Trustee and the Holders of the
Securities, and of the terms upon which the Securities and the Guarantees are,
and are to be, authenticated and delivered.

          The Indenture contains provisions for defeasance at any time of (a)
the entire Indebtedness on the Securities and (b) certain restrictive covenants
and related Defaults and Events of Default, in each case upon compliance or
noncompliance with certain conditions set forth therein.

          The Securities shall be senior unsecured obligations of the Company,
and shall rank pari passu with all existing and future Senior Indebtedness of
the Company and senior to all Subordinated Indebtedness of the Company.

                                    - 39 -
<PAGE>
 
          The Securities shall not be redeemable at the option of the Company
prior to April 1, 2000.  On or after that date, the Securities shall be
redeemable at the option of the Company, in whole or in part from time to time,
on not less than 30 nor more than 60 days' prior notice, mailed by first-class
mail to the Holders' registered addresses, in cash, in amounts of $1,000 or an
integral multiple of $1,000 at the following Redemption Prices (expressed as
percentages of the principal amount), if redeemed in the 12-month period
commencing April 1, of the years indicated below:

       Year                    Redemption
       ----                    ----------
       2000                    106.6875%
       2001                    105.0156%
       2002                    103.3438%
       2003                    101.6719%
       2004 and thereafter     100.0000%

in each case together with accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on relevant record
dates to receive interest due on an Interest Payment Date).  If less than all of
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata, by lot or by any other method the Trustee shall deem fair and
appropriate.

          In addition, at any time on or prior to April 1, 1998, the Company may
redeem, in part, up to $35,000,000 in aggregate principal amount of Securities
at a purchase price of 113% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Redemption Date, with the net proceeds of (i)
any public offering of Company Common Stock or (ii) any public offering of
common stock of GEV, but only to the extent that GEV contributes such net
proceeds to the Company as a capital contribution; provided that at least
$100,000,000 aggregate principal amount of the Securities must remain
outstanding after such redemption.  The Trustee shall select the Securities or
portions thereof to be redeemed pro rata, by lot or by any other method the
Trustee shall deem fair and appropriate.

          Upon the occurrence of a Change of Control, each Holder may require
the Company to repurchase all or a portion of such Holder's Securities in an
amount of $1,000 or integral multiples of $1,000, at a purchase price in cash
equal to 101% of the principal amount thereof, together with accrued and unpaid
interest, if any, to the date of repurchase.

          Under certain circumstances, in the event the Net Proceeds received by
the Company from one or more Asset Sales, which proceeds are not applied within
365 days subsequent to the consummation of the Asset Sale to repay permanently
any Senior Indebtedness then outstanding or to an investment in the Company

                                    - 40 -

or in one or more Restricted Subsidiaries in a Related Business, exceed
$5,000,000 the Company shall be required to apply such proceeds to repurchase
the Securities tendered to the Company for purchase at a price equal to at least
100% of the principal amount thereof, plus accrued interest, if any, to the date
of purchase pursuant to an offer to purchase made by the Company with respect to
the Securities.

          In the case of any redemption of Securities, interest installments
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities of record as of the close of business on the
relevant record date referred to on the face hereof.  Securities (or portions
thereof) for whose redemption and payment provision is made in accordance with
the Indenture shall cease to bear interest from and after the date of
redemption.

          In the event of redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof shall be issued in the
name of the Holder hereof upon the cancellation hereof.

          If an Event of Default shall occur and be continuing, the principal
amount of all the Securities may be declared due and payable in the manner and
with the effect provided in the Indenture.

          The Indenture permits, with certain exceptions (including certain
amendments permitted without the consent of any Holders) as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Subsidiary Guarantors and the rights of the Holders under the
Indenture and the Guarantees at any time by the Company, the Subsidiary
Guarantors and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Securities at the time Outstanding.  The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities at the time
Outstanding, on behalf of the Holders of all the Securities, to waive compliance
by the Company and the Subsidiary Guarantors with certain provisions of the
Indenture and the Guarantees and certain past Defaults under the Indenture and
the Guarantees and their consequences.  Any such consent or waiver by or on
behalf of the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent or waiver is made upon this
Security.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, any
Subsidiary Guarantor or any other

                                    - 41 -

make payments in respect of the Securities), which is absolute and
unconditional, to pay the principal of, premium, if any, and interest on this
Security at the times, place, and rate, and in the coin or currency, herein
prescribed.

          The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of a
different authorized denomination, as requested by the Holder surrendering the
same.

          No service charge shall be made for any registration of transfer or
exchange or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

          Prior to and at the time of due presentment of this Securities for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as
the owner hereof for all purposes, whether or not this Security is overdue, and
neither the Company, the Trustee nor any agent shall be affected by notice to
the contrary.

Exchange and Registration Rights Agreement dated as of April 20, 1995 (the
"Registration Rights Agreement") with the Initial Purchasers described therein.

                                 THE SECURITIES

          Section 301.                            Title and Terms.
                                                  --------------- 

          The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $135,000,000 in
principal amount of Securities plus any Exchange Notes which may be issued upon
consummation of an Exchange Offer, except for Securities authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of,
other Securities pursuant to Section 303, 304, 305, 306, 307, 308, 906, 1009,
1014 or 1108 hereof.

          The Securities shall be known and designated as the "13 3/8% Senior
Notes due 2005" of the Company.  The Stated Maturity of the principal amount of
the Securities shall be April 1, 2005, and the Securities shall each bear
interest at the rate of 13 3/8% from the Closing Date or from the most recent
Interest Payment Date to which interest has been paid, as the case may be,
payable on October 1, 1995 and semiannually thereafter on April 1 and October 1,
in each year, until the principal thereof is paid or duly provided for.  If a
Registration Default shall occur, the interest rate borne by the Securities
shall be increased by 25 basis points per annum at the beginning of each 90-day
period commencing at the date of any such Registration Default, up to a maximum
aggregate increase of 150 basis points per annum.  Upon (x) the filing or the
effectiveness of the Exchange Offer Registration Statement, (y) the consummation
of the Exchange Offer or (z) the filing or the effectiveness of the Shelf
Registration Statement, as the case may be, the interest rate borne by the
Securities shall be reduced from and including the date on which any of the
events specified in clauses (x), (y) or (z) above occur by the amount of any
such increase from the interest rate set forth above.

          The principal and interest on the U.S. Global Security shall be
payable to the Depositary or its nominee, as the case may be, as the sole
registered owner and the sole Holder of the U.S. Global Security represented
thereby.  The principal of, premium, if any, and interest on the Securities
shall be payable at the office or agency of the Company maintained for such
purpose; provided, however, that at the option of the Company interest may be
         --------  -------                                                   
paid by check mailed to addresses of the Persons entitled thereto as such
addresses shall appear on the Security Register.

          The Securities shall be redeemable as provided in Article Eleven.

                                    - 48 -
<PAGE>
 
          At the election of the Company, the entire Indebtedness on the
Securities or certain of the Company's obligations and covenants and certain
Events of Default thereunder may be defeased as provided in Article Four.

          Section 302.  Denominations.
                        ------------- 

          The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and any integral multiple thereof.

          Section 303.  Execution, Authentication, Delivery and Dating.
                        ---------------------------------------------- 

          The Securities shall be executed on behalf of the Company by one of
its Chairman of the Board, its President or one of its Vice Presidents under its
corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries.

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices on the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as
provided in this Indenture and not otherwise.

          Upon a Company Order, the Trustee shall authenticate and deliver an
additional series of notes in an aggregate principal amount not to exceed
$135,000,000 for issuance in exchange for all or a portion of the Initial
Securities previously issued and surrendered for cancellation pursuant to an
exchange offer registered under the Securities Act, in accordance with the
Registration Rights Agreement.  The Exchange Notes may have such distinctive
series designation and such changes in the form thereof as are specified in the
Company Order referred to in the preceding sentence, and shall be guaranteed by
the Subsidiary Guarantors on substantially identical terms as the Initial
Securities (except that the Guarantee of PCAC may be secured by Liens on its St.
Gabriel, Louisiana and Henderson, Nevada plants).

          Each Security shall be dated the date of its authentication.

                                    - 49 -
<PAGE>
 
          No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.

          In case the Company or any Subsidiary Guarantor, pursuant to Article
Eight, shall be consolidated, merged with or into any other Person or shall
sell, assign, convey, transfer or lease substantially all of its properties and
assets to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company or such
Subsidiary Guarantor shall have been merged, or the Person which shall have
received a sale, assignment, conveyance, transfer or lease as aforesaid, shall
have executed an indenture supplemental hereto with the Trustee pursuant to
Article Eight, any of the Securities authenticated or delivered prior to such
consolidation, merger, sale, assignment, conveyance, transfer or lease may, from
time to time, at the request of the successor Person, be exchanged for other
Securities executed in the name of the successor Person with such changes in
phraseology and form as may be appropriate, but otherwise in substance of like
tenor as the Securities surrendered for such exchange and of like principal
amount; and the Trustee, upon Company Request of the successor Person, shall
authenticate and deliver Securities as specified in such request for the purpose
of such exchange.  If Securities shall at any time be authenticated and
delivered in any new name of a successor Person pursuant to this Section in
exchange or substitution for or upon registration of transfer of any Securities,
such successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Securities at the time Outstanding for
Securities authenticated and delivered in such new name.

          The Trustee (at the expense of the Company) may appoint an
authenticating agent acceptable to the Company to authenticate Securities on
behalf of the Trustee.  Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  An authenticating agent has the same rights as
any Security Registrar or Paying Agent to deal with the Company and its
Affiliates.

          Section 304.  Temporary Securities.
                        -------------------- 

          Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall

                                    - 50 -
<PAGE>
 
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten or otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they are issued and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities may determine, as conclusively
evidenced by their execution of such Securities.

          After the preparation of definitive Securities, the temporary
Securities shall be exchangeable for definitive Securities upon surrender of the
temporary Securities at the office or agency of the Company designated for such
purpose pursuant to Section 1002 hereof, without charge to the Holder.  Upon
surrender for cancellation of any one or more temporary Securities the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of authorized
denominations.  Until so exchanged the temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

          Section 305.  Registration of Transfer and Exchange.
                        ------------------------------------- 

          All provisions of this Section 305 shall be subject to Section 307
hereof.

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee, or such other office as the Trustee may designate, a register (the
register maintained in such office and in any other office or agency designated
pursuant to Section 1002 hereof being herein sometimes referred to as the
"Security Register") in which, subject to such reasonable regulations as the
Security Registrar may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities.  The Trustee or an agent thereof
or of the Company shall initially be the "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.

          Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated pursuant to Section 1002 hereof, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series of any authorized denomination or denominations, of a like
aggregate principal amount.

          Any Holder of the U.S. Global Security shall, by acceptance of such
U.S. Global Security, agree that transfers of beneficial interests in such U.S.
Global Security, may be effected only through a book-entry system maintained by
the

                                    - 51 -
<PAGE>
 
Holder of such U.S. Global Security (or its agent), and that ownership of a
beneficial interest in the Security shall be required to be reflected in a book
entry.

          At the option of the Holder, Securities may be exchanged for other
Securities of any authorized denomination or denominations (including an
exchange of Initial Securities for Exchange Notes), of a like aggregate
principal amount, upon surrender of the Securities to be exchanged at such
office or agency.  Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities of the same series which the Holder making the exchange is entitled
to receive; provided that no exchanges of Initial Securities for Exchange Notes
            --------                                                           
shall occur until a Registration Statement shall have been declared effective by
the Commission and that any Initial Securities that are exchanged for Exchange
Notes shall be canceled by the Trustee.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
Indebtedness, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

          Every Security presented or surrendered for registration of transfer,
or for exchange or redemption shall (if so required by the Company or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Company and the Security Registrar, duly executed by
the Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made to a Holder for any registration of
transfer or exchange or redemption of Securities, but the Company may require
payment of a sum sufficient to pay all documentary, stamp or similar issue or
transfer taxes or other governmental charges that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges of Initial Securities for Exchange Notes and exchanges pursuant to
Section 303, 304, 305, 306, 307, 308, 906, 1009, 1014 or 1108 hereof not
involving any transfer.

          The Company shall not be required (a) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of business
(i) 15 days before the date of selection of Securities for redemption under
Section 1104 hereof and ending at the close of business on the day of such
mailing or (ii) 15 days before an Interest Payment Date and ending on the close
of business on the Interest Payment Date, or (b) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of Securities being redeemed in part.

          Section 306.  Book-Entry Provisions for U.S. Global Security.
                        ---------------------------------------------- 

          All provisions of this Section 306 shall be subject to Section 307
hereof.

          (a)  The U.S. Global Security initially shall (i) be registered in the
name of the Depositary for such U.S. Global Security or the nominee of such
Depositary, (ii) be delivered to the Trustee as custodian for such Depositary
and (iii) bear legends as set forth in Section 202 hereof.

          Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any U.S. Global Security
held on their behalf by the Depositary, or the Trustee as its custodian, or
under the U.S. Global Security, and the Depositary may be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the absolute
owner of such U.S. Global Security for all purposes whatsoever.  Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Trustee or any
agent of the Company or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or
impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any
Security.

          (b)  Transfers of the U.S. Global Security shall be limited to
transfers of such U.S. Global Security in whole, but not in part, to the
Depositary, its successors or their respective nominees.  Interests of
beneficial owners in the U.S. Global Security may be transferred in accordance
with the rules and procedures of the Depositary and the provisions of Section
307 hereof.  Beneficial owners may obtain Physical Securities in exchange for
their beneficial interests in the U.S. Global Security upon request in
accordance with the Depositary's and the Registrar's procedures.  In addition,
Physical Securities shall be transferred to all beneficial owners in exchange
for their beneficial interests in the U.S. Global Security if (i) the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for the U.S. Global Security and a successor depositary is not appointed by the
Company within 90 days of such notice or (ii) an Event of Default has occurred
and is continuing and the Security Registrar has received a request from the
Depositary.

          (c)  In connection with any transfer of a portion of the beneficial
interest in the U.S. Global Security to beneficial owners pursuant to Subsection
(b) of this Section, the Security Registrar shall reflect on its books and
records the date and a decrease in the principal amount of the U.S. Global
Security in an amount equal to the principal amount of the beneficial

                                    - 53 -
<PAGE>
 
interest in the U.S. Global Security to be transferred, and the Company shall
execute, and the Trustee shall authenticate and deliver, one or more Physical
Securities of like tenor and amount.

          (d)  In connection with the transfer of the entire U.S. Global
Security to beneficial owners pursuant to Subsection (b) of this Section, the
U.S. Global Security shall be surrendered to the Trustee for cancellation, and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the U.S. Global Security, an equal aggregate principal
amount of Physical Securities of authorized denominations.

          (e)  Any Physical Security delivered in exchange for an interest in
the U.S. Global Security pursuant to Subsection (b) or Subsection (c) of this
Section shall, except as otherwise provided by paragraph (a)(i)(x) and paragraph
(d) of Section 307 hereof, bear the applicable legend regarding transfer
restrictions applicable to the Physical Security set forth in Section 202
hereof.

          (f)  The registered Holder of the U.S. Global Security may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold interests through Agent Members, to take any action which a Holder
is entitled to take under this Indenture or the Securities.

                                                  ---------        

              (ii)  If the proposed transferor is an Agent Member holding a
          beneficial interest in the U.S. Global Security, upon receipt by the
          Security Registrar of (x) the documents, if any, required by paragraph

          principal amount of the beneficial interest in the U.S. Global
          Security to be transferred, and the Company shall execute, and the
          Trustee shall authenticate and deliver, one or more Physical
          Securities of like tenor and amount.

          (b)  Transfers to QIBs.  The following provisions shall apply with

     respect to the registration of any proposed transfer of a Security to a
     QIB:

               (i)  If the Security to be transferred consists of Physical
          Securities, the Security Registrar shall register the transfer if such
          transfer is being made by a proposed transferor who has checked the
          box provided for on the form of Security stating, or has otherwise
          advised the Company and the Security Registrar in writing, that the
          sale has been made in compliance with the provisions of Rule 144A to a
          transferee who has signed the certification provided for on the form
          of Security stating, or has otherwise advised the Company and the
          Security Registrar in writing, that it is purchasing the Security for
          its own account or an account with respect to which it exercises sole
          investment discretion and that it and any such account is a QIB within
          the meaning of Rule 144A, and is aware that the sale to it is being
          made in reliance on Rule 144A and acknowledges that it has received
          such information regarding the Company as it has requested pursuant to
          Rule 144A or has determined not to request such information and that
          it is aware that the transferor is relying upon its foregoing
          representations in order to claim the exemption from registration
          provided by Rule 144A.

               (ii)  If the proposed transferee is an Agent Member, and the
          Security to be transferred consists of Physical Securities, upon
          receipt by the Security Registrar of instructions given in accordance
          with the Depositary's and the Security Registrar's procedures, the
          Security Registrar shall reflect on its books and

          Physical Securities to be transferred, and the Trustee shall cancel
          the Physical Security so transferred.

          (c)  Private Placement Legend.  Any Security authenticated and issued
               ------------------------                                        
     hereunder shall not be required to bear the legend set forth in Section 202
     hereof, if such Security shall be issued upon:

               (i)  the transfer or exchange of a Security and contemporaneously
          therewith the Company shall have received an Opinion of Counsel, at
          its expense, in form and substance reasonably satisfactory to the
          Company, to the effect that such Security to be issued upon such
          transfer or exchange may be so issued without such legend because (A)
          such Security is being exchanged for an Exchange Note, (B) such
          Security shall have been registered under the Securities Act, the
          registration statement in connection therewith shall have been
          declared effective and such Security shall have been disposed of
          pursuant to such effective registration statement, or (C) the
          circumstances contemplated by paragraph (a)(i)(x) of this Section 307
          exist, and the Company shall have delivered to the Trustee and the
          Security Registrar a copy of such Opinion of Counsel together with an
          Officers' Certificate directing the Trustee and the Security Registrar
          to deliver an unlegended Security in connection with such transfer or
          exchange; such Officers' Certificate and Opinion of Counsel shall be
          delivered by the Company as soon as practicable after its receipt of a
          written request by a Holder for such a transfer or exchange; or

              (ii)  the transfer or exchange of a Security not bearing such
          legend.

          (d)  General.
               ------- 

               (i)  By its acceptance of any Security bearing the Private
          Placement Legend, each Holder of such a Security acknowledges the
          restrictions on transfer of such Security set forth in this Indenture
          and in the Private Placement Legend and agrees that it shall transfer
          such Security only as provided in this Indenture.

              (ii)  Prior to any transfer or exchange of a legended Security for
          another legended Security, the Company shall have received an opinion
          of counsel of the Holder (which may include in-house counsel of such

                                    - 56 -
<PAGE>
 
          Holder experienced in matters of Federal securities law), at its
          expense, in form and substance reasonably satisfactory to the Company
          to the effect that such transfer does not require registration under
          the Securities Act and the Company shall have delivered to the Trustee
          and the Security Registrar a copy of such opinion of counsel of the
          Holder together with an Officers' Certificate directing the Trustee
          and the Security Registrar to transfer or exchange the legended
          Security for another legended Security.

          The Trustee and the Security Registrar shall forward copies of all
letters, notices and other written communications received pursuant to Section
306 hereof or this Section 307 to the Company for approval prior to any transfer
or exchange.

          Notwithstanding anything to the contrary set forth herein, the Trustee
and the Security Registrar shall have no duty to monitor compliance with any
Federal, state or other securities laws.

          Section 308.   Mutilated, Destroyed, Lost and Stolen Securities.
                         ------------------------------------------------ 

          If (a) any mutilated Security is surrendered to the Trustee, or (b)
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, and there is delivered to the
Company, each Subsidiary Guarantor and the Trustee, such security or indemnity,
in each case, as may be required by them to save each of them harmless, then, in
the absence of notice to the Company, any Subsidiary Guarantor or the Trustee
that such Security has been acquired by a bona fide purchaser, the Company shall
execute and upon its written request the Trustee shall authenticate and deliver,
in exchange for any such mutilated Security or in lieu of any such destroyed,
lost or stolen Security, a replacement Security of like tenor and principal
amount, bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a replacement Security, pay such Security.

          Upon the issuance of any replacement Securities under this Section,
the Company may require the payment of a sum sufficient to pay all documentary,
stamp or similar issue or transfer taxes or other governmental charges that may
be imposed in relation thereof and any other expenses (including the fees and
expenses of the Trustee) connected therewith.


                                    - 57 -
<PAGE>
 
          Every replacement Security issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company and the Subsidiary Guarantors, whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

          Section 309.   Payment of Interest; Interest Rights Preserved.
                         ---------------------------------------------- 

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security is registered at the close of business on the Regular
Record Date for such interest.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date and interest on such
defaulted interest at the then applicable interest rate borne by the Securities,
to the extent lawful (such defaulted interest and interest thereon herein
collectively called "Defaulted Interest") shall forthwith cease to be payable to
the Holder on the Regular Record Date; and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in Subsection (a) or
(b) below:

          (a)  the Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Security and the date (not less than 30 days after such
     notice) of the proposed payment, and at the same time the Company shall
     deposit with the Trustee an amount of money equal to the aggregate amount
     proposed to be paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit prior to the date
     of the proposed payment, such money when deposited to be held in trust for
     the benefit of the Persons entitled to such Defaulted Interest as in this
     Subsection provided.  Thereupon the Trustee shall fix a Special Record Date
     for the payment of such Defaulted Interest which shall be not more than 15
     days and not less than 10 days prior to the

                                    - 58 -
<PAGE>
 
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment.  The Trustee shall
     promptly notify the Company in writing of such Special Record Date.  In the
     name and at the expense of the Company, the Trustee shall cause notice of
     the proposed payment of such Defaulted Interest and the Special Record Date
     therefor to be mailed, first-class postage prepaid, to each Holder at his
     address as it appears in the Security Register, not less than 10 days prior
     to such Special Record Date.  Notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities are registered on such Special Record Date and shall no
     longer be payable pursuant to the following Subsection (b).

          (b)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after written notice given
     by the Company to the Trustee of the proposed payment pursuant to this
     Subsection, such payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security (including any Exchange Security issued in
exchange for an Initial Security) shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.

                         --------------------- 

          The Company, any Subsidiary Guarantor, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name any Security is
registered as the owner of such Security for the purpose of receiving payment of

such Security and for all other purposes whatsoever, whether or not such
Security is overdue, and neither the Company, any Subsidiary Guarantor, the
Trustee nor any agent of the Company, any Subsidiary Guarantor or the Trustee
shall be affected by notice to the contrary.

          Section 311.   Cancellation.
                         ------------ 

          All Securities surrendered for payment, purchase, redemption,
registration of transfer or exchange shall be delivered to the Trustee and, if
not already canceled, shall be promptly canceled by it.  The Company and any
Subsidiary Guarantor may at any time deliver to the Trustee for cancellation

<PAGE>
 
any Securities previously authenticated and delivered hereunder which the
Company or such Subsidiary Guarantor may have acquired in any manner whatsoever,
and all Securities so delivered shall be promptly canceled by the Trustee.  No
Securities shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section, except as expressly permitted by this
Indenture.  All canceled Securities held by the Trustee shall be destroyed and
certification of their destruction delivered to the Company.  The Trustee shall
provide the Company a list of all Securities that have been canceled from time
to time as requested by the Company.

                         ----------------------- 

          Interest on the Securities shall be computed on the basis of a 360-day

                         ----------------- 

          Prior to 10:00 a.m., New York City time, on each Interest Payment Date

Agent in immediately available funds money sufficient to make cash payments, if
any, due on such Interest Payment Date or at Maturity, as the case may be, in a
timely manner which permits the Trustee or such Paying Agent to remit payment to
the Holders on such Interest Payment Date or at Maturity, as the case may be.

          Section 314.   CUSIP Number.
                         ------------ 

          The Company in issuing the Securities may use a "CUSIP" number(s), and
if so, the Trustee shall use the CUSIP number(s) in notices of redemption or
exchange as a convenience to Holders, provided that any such notice may state
                                      --------                               
that no representation is made as to the correctness or accuracy of the CUSIP
number(s) printed in the notice or on the Securities and that reliance may be

Defeasance.
---------- 

          The Company may, at its option by Board Resolution, at any time, with
respect to the Securities, elect to have either Section 402 or Section 403
hereof be applied to all of the Outstanding Securities (the "Defeased
Securities"), upon

                                    - 60 -
<PAGE>
 
compliance with the conditions set forth below in this Article Four.

          Section 402.   Defeasance and Discharge.
                         ------------------------ 

          Upon the Company's exercise under Section 401 hereof of the option
applicable to this Section 402, the Company, each of the Subsidiary Guarantors
and any other obligor upon the Securities, if any, shall be deemed to have been
discharged from its obligations with respect to the Defeased Securities on the
date the conditions set forth below are satisfied (hereinafter, "defeasance").
For this purpose, such defeasance means that the Company shall be deemed to have
paid and discharged the entire Indebtedness represented by the Defeased
Securities, which shall thereafter be deemed to be "Outstanding" only for the
purposes of Section 405 hereof and the other Section of this Indenture referred
to in (a) and (b) below, and to have satisfied all its other obligations under
such Securities and this Indenture insofar as such Securities are concerned (and
the Trustee, at the expense of the Company, and, upon written request, shall
execute proper instruments acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged hereunder:  (a) the
rights of Holders of Defeased Securities to receive, solely from the trust fund
described in Section 404 hereof and as more fully set forth in such Section,
payments in respect of the principal of, premium if any, and interest on such
Securities when such payments are due, (b) the Company's obligations with
respect to such Defeased Securities under Sections 304, 305, 308, 1002 and 1018
hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee
hereunder including, without limitation, the Trustee's rights under Section 606
hereof and the Company's obligations in connection therewith, and (d) this
Article Four.  Subject to compliance with this Article Four, the Company may
exercise its option under this Section 402 notwithstanding the prior exercise of
its option under Section 403 hereof with respect to the Securities.

          Section 403.   Covenant Defeasance.
                         ------------------- 

          Upon the Company's exercise under Section 401 hereof of the option
applicable to this Section 403, the Company and each Subsidiary Guarantor shall
be released from its obligations under any covenant or provision contained or
referred to in Sections 1004, 1005, 1006, 1007, 1008, 1009, 1010, 1011, 1012,
1014, 1015, 1016, 1019 and 1020 hereof with respect to the Defeased Securities
on and after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"), and the Defeased Securities shall thereafter be deemed
to be not "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to

                                    - 61 -
<PAGE>
 
be deemed "Outstanding" for all other purposes hereunder.  For this purpose,
such covenant defeasance means that, with respect to the Defeased Securities,
the Company and each Subsidiary Guarantor may omit to comply with and shall have
no liability in respect of any term, condition or limitation set forth in any
such Section or Article, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in any
other document and such omission to comply shall not constitute a Default or an
Event of Default under Section 501(3) or (4) hereof but, except as specified
above, the remainder of this Indenture and such Defeased Securities shall be
unaffected thereby.

          Section 404.   Conditions to Defeasance or Covenant Defeasance.
                         ----------------------------------------------- 

          The following shall be the conditions to application of either Section
402 or Section 403 hereof to the Defeased Securities:

          (1)  The Company shall irrevocably have deposited or caused to be

     Article Four applicable to it) as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (a)

     combination thereof, sufficient, in the opinion of a nationally recognized
     firm of independent public accountants or a nationally recognized
     investment banking firm expressed in a written certification thereof
     delivered to the Trustee, to pay and discharge and which shall be applied
     by the Trustee (or other qualifying trustee) to pay and discharge the
     principal of, premium, if any, and interest on the Defeased Securities on
     the Stated Maturity of such principal or installment of principal or
     interest (such date being referred to as the "Defeasance Redemption Date"),
     if when exercising under Section 401 hereof either its option applicable to
     Section 402 hereof or its option applicable to Section 403 hereof, the
     Company shall have delivered to the Trustee an irrevocable notice to redeem
     all of the Outstanding Securities on the Defeasance Redemption Date);

     such United States dollars or the proceeds of such U.S. Government
     Obligations to said payments with respect to the Securities.

          (2) In the case of an election under Section 402 hereof, the Company
     shall have delivered to the Trustee an Opinion of Independent Counsel in
     the United States of America stating that (A) the Company has received from
     the Internal Revenue Service a ruling or (B) since the date of this
     Indenture, there has been a change in the applicable federal income tax
     law, including by means of a Revenue Ruling published by the Internal
     Revenue Service, in either case to the effect that, and based thereon such
     Opinion of Independent Counsel in the United States of America shall
     confirm that, the Holders of the Outstanding Securities will not recognize
     income, gain or loss for federal income tax purposes as a result of such
     defeasance and will be subject to federal income tax on the same amounts,
     in the same manner and at the same times as would have been the case if
     such defeasance had not occurred.

          (3)  In the case of an election under Section 403 hereof, the Company
     shall have delivered to the Trustee an Opinion of Independent Counsel in
     the United States of America to the effect that the Holders of the
     Outstanding Securities will not recognize income, gain or loss for federal
     income tax purposes as a result of such covenant defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such covenant defeasance
     had not occurred.

          (4)  No Default or Event of Default shall have occurred and be
     continuing on the date of such deposit or insofar as Subsections 501(9) or
     (10) hereof are concerned, at any time during the period ending on the 91st
     day after the date of deposit.

          (5)  Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a Default under, any material
     agreement or instrument (other than this Indenture) to which the Company or
     any Subsidiary Guarantor is a party or by which it is bound.

          (6)  The Company shall have delivered to the Trustee an Opinion of
     Independent Counsel to the effect that after the 91st day following the
     deposit, the trust funds will not be subject to the effect of any
     applicable bankruptcy, insolvency, reorganization or similar laws affecting
     creditors' rights generally.

          (7)  The Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the Holders of the Securities or any Guarantee over
     the other creditors of the Company or any Subsidiary Guarantor with the
     intent of

                                    - 63 -
<PAGE>
 
     defeating, hindering, delaying or defrauding creditors of the Company, any
     Subsidiary Guarantor or others.

          (8)  The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Independent Counsel, each stating that all
     conditions precedent provided for relating to either the defeasance under
     Section 402 hereof or the covenant defeasance under Section 403 hereof (as
     the case may be) have been complied with as contemplated by this Section
     404.

Opinions of Counsel or Opinions of Independent Counsel required to be delivered
under this Section may have qualifications customary for opinions of the type
required and counsel delivering such opinions may rely on certificates of the
Company or government or other officials customary for opinions of the type
required, including certificates certifying as to matters of fact, including
that various financial covenants have been complied with.

                         -----------------------------------------------------
Held in Trust; Other Miscellaneous Provisions.
--------------------------------------------- 

          Subject to the provisions of the last paragraph of Section 1018
hereof, all United States dollars and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee (or other qualifying trustee--
collectively for purposes of this Section 405, the "Trustee") pursuant to
Section 404 hereof in respect of the Defeased Securities shall be held in trust
and applied by the Trustee, in accordance with the provisions of such Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal, premium, if any, and interest, but such money
need not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 404 hereof or the principal and interest received
in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Defeased Securities.

          Anything in this Article Four to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any United States dollars or U.S. Government Obligations held by it as
provided in Section 404 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of

                                    - 64 -

the amount thereof which would then be required to be deposited to effect
defeasance or covenant defeasance.

          Section 406.   Reinstatement.
                         ------------- 

          If the Trustee or Paying Agent is unable to apply any United States
dollars or U.S. Government Obligations in accordance with Section 402 or 403
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and each Subsidiary Guarantor's obligations
under this Indenture and the Securities (including, without limitation, the
provisions of Article Thirteen hereof) shall be revived and reinstated as though
no deposit had occurred pursuant to Section 402 or 403 hereof, as the case may
be, until such time as the Trustee or Paying Agent is permitted to apply all
such United States dollars or U.S. Government Obligations in accordance with
Section 402 or 403 hereof, as the case may be; provided, however, that if the
                                               --------  -------             
Company makes any payment to the Trustee or Paying Agent of principal of,
premium, if any, or interest on any Security following the reinstatement of its
obligations, the Trustee or Paying Agent shall promptly pay any such amount to
the Holders of the Securities and the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or Paying Agent.

          Section 407.   Repayment of the Company.
                         ------------------------ 

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Security and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its written request or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Issuer as trustee thereof,
shall thereupon cease, provided, however, that the Trustee or such Paying Agent,
                       --------  -------                                        
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than thirty (30) days
from the date of such notification or publication, any unclaimed balance of such
money then remaining shall promptly be repaid to the Company.

                                    REMEDIES

          Section 501.  Events of Default.
                        ----------------- 

          An "Event of Default" shall occur if:

          (1)  there shall be a default in the payment of interest on any
     Security when the same becomes due and payable and the Default continues
     for a period of thirty (30) days;

          (2)  there shall be a default in the payment of the principal of, or
     premium with respect to, any Security when the same becomes due and
     payable, at maturity, upon redemption, in connection with a Change of
     Control, an Asset Sale or otherwise;

          (3)  the Company or any Subsidiary Guarantor fails to observe or
     perform any covenant, condition or agreement on the part of the Company or
     such Subsidiary Guarantor to be observed or performed pursuant to Section
     1006, 1008, 1009, 1010, 1012, 1014, 1019, 1020 or Article Eight hereof;

          (4)  the Company or any Subsidiary Guarantor fails to observe or
     perform any other covenant, condition or agreement in this Indenture or the
     Securities and such failure continues for the period and after the notice
     specified below;

          (5)  the Company denies or disaffirms its obligations under this
     Indenture or the Securities;

          (6) a Subsidiary Guarantor denies or disaffirms its obligations under
     its Guarantee, or any Guarantee for any reason ceases to be, or is asserted
     in writing by any Subsidiary Guarantor or the Company not to be, in full
     force and effect and enforceable in accordance with its terms, except to
     the extent contemplated by the Indenture and any such Guarantee;

          (7)  a default occurs under any Indebtedness of the Company or any of
     its Subsidiaries (other than the Securities or the Guarantees), whether
     such Indebtedness now exists or is created after the Closing Date if either
     (A) such default results from the failure to pay the final scheduled
     principal installment in respect of any such Indebtedness on the stated
     maturity date thereof (after giving effect to any grace period) or (B) as a
     result of such default, the maturity of such Indebtedness has been
     accelerated prior to its express maturity and, in each case,

                                    - 66 -
<PAGE>
 
     the principal amount of such Indebtedness, together with the principal
     amount of all other Indebtedness with respect to which the principal amount
     remains unpaid at its final maturity (after giving effect to any grace
     period in respect of such final scheduled principal installment) or the
     maturity of which has been so accelerated, aggregates $5,000,000 or more;

          (8)  a final judgment or final judgments for the payment of money are
     entered by a court or courts of competent jurisdiction against the Company
     or any of its Restricted Subsidiaries and such judgment or judgments remain
     undischarged, unbonded or unstayed for a period of sixty (60) days,
     provided that the aggregate of all such judgments (other than any judgment
     as to which and only to the extent, a reputable insurance company has
     acknowledged coverage of such claim in writing) exceeds $5,000,000;

          (9)  the Company, any Subsidiary Guarantor or any other Restricted
     Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

               (a)  commences a voluntary case,

               (b)  consents to the entry of an order for relief against it in
          an involuntary case in which it is a debtor,

               (c)  consents to the appointment of a Custodian of it or for all
          or substantially all of its property,

               (d)  makes a general assignment for the benefit of its creditors,
          or

               (e) admits in writing its inability to pay debts as the same
          become due; or

          (10)  a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:

               (a) is for relief against the Company, any Subsidiary Guarantor
          or any other Restricted Subsidiary in an involuntary case in which it
          is a debtor,

               (b) appoints a Custodian of the Company, any Subsidiary Guarantor
          or any other Restricted Subsidiary or for all or substantially all of
          their property,

               (c) orders the liquidation of the Company, any Subsidiary
          Guarantor or any other Restricted Subsidiary,

                                    - 67 -
<PAGE>
 
     and the order or decree remains unstayed and in effect for sixty (60) days.

          The term "Custodian" means any receiver, trustee, assignee, liquidator
or similar official under any Bankruptcy Law.

          A Default under clause (4) is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the Securities then Outstanding notify the Company and the Trustee, of the
Default and the Company does not cure the Default within sixty (60) days after
receipt of such notice.  The notice must specify the Default, demand that it be
remedied and state that the notice is a "Notice of Default."

          The failure to make any payment on the Securities when due shall,
after the expiration date of any applicable grace period, constitute an Event of
Default under this Indenture.

          Section 502.   Acceleration.
                         ------------ 

          If an Event of Default (other than an Event of Default specified in
clauses (9) and (10) of Section 501 hereof) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of at least 25% in principal
amount of the Securities then Outstanding by written notice to the Company and
the Trustee, may declare the unpaid principal of and any accrued interest on all
the Securities to be due and payable.  Upon such declaration the principal and
interest shall be due and payable immediately.  If an Event of Default specified
in clause (9) or (10) of Section 501 hereof occurs, such an amount shall ipso
                                                                         ----
facto become and be immediately due and payable without any declaration or other
-----                                                                           
act on the part of the Trustee or any Holder.  The Holders of a majority (or, in
the case of the failure to make a Change of Control Offer pursuant to Section
1014 hereof, two-thirds) in principal amount of Securities then Outstanding by
written notice to the Trustee may rescind an acceleration and its consequences
if the rescission would not conflict with any judgment or decree and if:

          (a) the Company has paid or deposited with the Trustee a sum
     sufficient to pay

               (i)  all sums paid or advanced by the Trustee under this
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Trustee, its agents and counsel,

              (ii)  all overdue interest on all Securities,

                                    - 68 -
<PAGE>
 
             (iii)  the principal of and premium, if any, on any Securities
          which have become due otherwise than by such declaration of
          acceleration and interest thereon at a rate borne by the Securities,
          and

              (iv)  to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate borne by the Securities;
          and

          (b) all Events of Default, other than the non-payment of principal of
     the Securities which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 504 hereof.
     No such rescission shall affect any subsequent Default or impair any right
     consequent thereon provided in Section 504 hereof.

          Section 503.   Other Remedies.
                         -------------- 

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy (under this Indenture or otherwise) to collect the
payment of principal, premium, if any, or interest on the Securities or to
enforce the performance of any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default.

          No right or remedy herein conferred upon or reserved to the Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          Section 504.   Waiver of Past Defaults.
                         ----------------------- 

          Holders of a majority (or, in the case of the failure by the Company
to make a Change of Control Offer pursuant to Section 1014 hereof, two-thirds)
in aggregate principal amount of the Securities then Outstanding by notice to
the Trustee may waive an existing Default or Event of Default and its
consequences, except a continuing Default or Event of Default in the payment of
the principal of or interest on any Security held by a non-consenting Holder.
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall

                                    - 69 -
<PAGE>
 
be deemed to have been cured for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

          Section 505.   Control by Majority.
                         ------------------- 

          The Holders of a majority in principal amount of the Securities then
Outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on it.  However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that the Trustee determines may be unduly
prejudicial to the rights of other Holders, or that may involve the Trustee in
personal liability.

          Section 506.   Limitation on Suits.
                         ------------------- 

          A Holder may pursue a remedy with respect to this Indenture or the
Securities only if:

          (1)  the Holder gives to the Trustee written notice of a continuing
     Event of Default;

          (2)  the Holders of at least 25% in principal amount of the Securities
     then Outstanding make a written request to the Trustee to pursue the
     remedy;

          (3)  such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

          (4)  the Trustee does not comply with the request within sixty (60)
     days after receipt of the request and the offer and, if requested, the
     provision of the indemnity; and

          (5)  during such sixty (60) day period the Holders of a majority in
     principal amount of the Securities then Outstanding do not give the Trustee
     a direction inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or
to obtain a preference or priority over another Holder.

          Section 507.   Rights of Holders to Receive Payment.
                         ------------------------------------ 

          Notwithstanding any other provision of this Indenture, but subject to
Article Thirteen the right of any Holder of a Security to receive payment of
principal, premium, if any, and interest on the Security, on or after the
respective due dates expressed in the Security (or, in the case of redemption or
repurchase, on the Redemption Date or repurchase date), or to

                                    - 70 -
<PAGE>
 
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of the Holder,
subject to Article Thirteen.

          Section 508.   Collection Suit by Trustee.
                         -------------------------- 

          If an Event of Default specified in Section 501(1) or (2) hereof
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company or any
Subsidiary Guarantor for the whole amount of principal, premium, if any, and
interest remaining unpaid on the Securities and interest on overdue principal
and, to the extent lawful, premium and interest and such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, subject to Article Thirteen.

          If the Company or any Subsidiary Guarantor, as the case may be, fails
to pay such amounts forthwith upon such demand, the Trustee, in its own name and
as trustee of an express trust, may institute a judicial proceeding for the
collection of the sums so due and unpaid and may prosecute such proceeding to
judgment or final decree, and may enforce the same against the Company or any
Subsidiary Guarantor or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any Subsidiary Guarantor or any other obligor
upon the Securities, wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders under this Indenture or the Guarantees by such appropriate private or
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce such rights, including, seeking recourse against any Subsidiary
Guarantor pursuant to the terms of any Guarantee, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein or therein, or to enforce any other proper
remedy, including, without limitation, seeking recourse against any Subsidiary
Guarantor pursuant to the terms of a Guarantee, or to enforce any other proper
remedy, subject however to Section 505 hereof.

          Section 509.   Trustee May File Proofs of Claim.
                         -------------------------------- 

          The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company or any

                                    - 71 -
<PAGE>
 
Subsidiary Guarantor or any other obligor upon the Securities, their creditors
or their property and shall be entitled and empowered, subject to Article
Thirteen, to collect, receive and distribute any money or other property payable
or deliverable on any such claims and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee, and in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 606 hereof.  To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 606 hereof out of the estate in
any such proceeding shall be denied for any reason, payment of the same shall be
secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties which the Holders of the
Securities may be entitled to receive in such proceeding whether in liquidation
or under any plan of reorganization or arrangement or otherwise.  Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

          Section 510.   Priorities.
                         ----------

          First:  to the Trustee, its agents and attorneys for amounts due under
     Section 606 hereof, including payment of all compensation, expenses and
     liabilities incurred, and all advances made, by the Trustee and the costs
     and expenses of collection;

          Second:  subject to Article Thirteen, to Holders for amounts due and
     unpaid on the Securities for principal, premium, if any, and interest
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on the Securities for principal, premium, if any,
     and interest, respectively;

          Third:  subject to Article Thirteen, without duplication, to Holders
     for any other Indenture Obligations owing to the Holders under this
     Indenture or the Securities; and

                                    - 72 -
<PAGE>
 
          Fourth:  subject to Article Thirteen, to the Company or to such party
     as a court of competent jurisdiction shall direct.

          The Trustee may fix a record date and payment date for any payment to
Holders.

          Section 511.   Undertaking for Costs.
                         --------------------- 

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 507 hereof or a suit by Holders of more than 10% in
principal amount of the Securities then Outstanding or to any suit instituted by
any Holder for the enforcement of the payment of the principal of, premium, if
any, or interest on any Security on or after the respective Stated Maturities
expressed in such Security (or, in the case of redemption or repurchase, on or
after the Redemption Date or repurchase date).

          Section 512.   Waiver of Stay, Extension or Usury Laws.
                         ----------------------------------------

          Each of the Company and any Subsidiary Guarantor covenants (to the
extent that it may lawfully do so) that it shall not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law or any usury or other law wherever enacted, now or at

that it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law, and covenants that it shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.

          The Trustee, any Paying Agent, Security Registrar or any other agent
of the Company, in its individual or any other capacity, may become the owner or
pledgee of Securities, with the same rights it would have if it were not the

Trust Indenture Act Sections 310 and 311, may otherwise deal with the Company
and receive, collect, hold and retain collections from the Company with the same
rights it would have if it were not the Trustee, Paying Agent, Security
Registrar or such other agent.

          Section 605.   Money Held in Trust.
                         ------------------- 

          All moneys received by the Trustee shall, until used or applied as

Trustee pursuant to Article Four, the Trustee may invest all moneys received by
the Trustee, until used or applied as herein provided, in Cash Equivalents in

                         ---------------------------------------------------
Prior Claim.
----------- 

          The Company covenants and agrees to pay to the Trustee from time to
time, and the Trustee shall be entitled to, reasonable compensation for all
services rendered by it hereunder (which shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust) and the
Company covenants and agrees to pay or reimburse the Trustee and each
predecessor Trustee upon its request for all reasonable

                                    - 76 -
<PAGE>
 
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence or bad faith.
The Company also covenants to indemnify the Trustee and each predecessor Trustee
for, and to hold it harmless against, any loss, liability, tax, assessment or
other governmental charge (other than taxes applicable to the Trustee's
compensation hereunder) or expense incurred without gross negligence or bad
faith on such Trustee's part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and such
Trustee's duties hereunder, including enforcement of this Section 606 and also
including any liability which the Trustee may incur as a result of failure to
withhold, pay or report any tax, assessment or other governmental charge, and
the costs and expenses of defending itself against or investigating any claim of
liability in the premises.  The obligations of the Company under this Section to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for expenses, disbursements
and advances shall constitute an additional obligation hereunder and shall
survive the satisfaction and discharge of this Indenture, or the resignation or
removal of any Trustee.

          To secure the Company's payment obligations in this Section 606, the
Trustee shall have a Lien prior to the Securities on all money or property held
or collected by the Trustee, in its capacity as Trustee, except money or
property held in trust to pay principal of or interest on particular Securities.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(9) or (10), the expenses and
the compensation for the services shall be preferred over the status of Holders
in any proceeding under any Bankruptcy Law and are intended to constitute
expenses of administration under any Bankruptcy Law.

          Section 607.   Conflicting Interests.
                         ---------------------

Trust Indenture Act.

          Section 608.   Corporate Trustee Required; Eligibility.
                         --------------------------------------- 

          There shall at all times be a Trustee hereunder which shall be
eligible to act as trustee under Trust Indenture Act Section 310(a)(1) and which
shall have a combined capital and surplus of at least $50,000,000 or which shall
be a wholly owned

                                    - 77 -

subsidiary of a company that has a combined capital and surplus of at least
$50,000,000, to the extent there is an institution eligible and willing to
serve.  If the Trustee does not have an office in The City of New York, the
Trustee may appoint an agent in The City of New York reasonably acceptable to
the Company to conduct any activities which the Trustee may be required under
this Indenture to conduct in The City of New York.  If the Trustee does not have
an office in The City of New York or has not appointed an agent in The City of
New York, the Trustee shall be a participant in the Depository Trust Company and
FAST distribution systems.  If such corporation published reports of condition
at least annually, pursuant to law or to the requirements of federal, state,
territorial or District of Columbia supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section,
the Trustee shall resign immediately in the manner and with the effect
hereinafter specified in this Article Six.

                         -------------------------------------------------
Trustee.
------- 

          (a)  No resignation or removal of the Trustee and no appointment of a
successor trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor trustee under Section 610 hereof.

          (b)  The Trustee, or any trustee or trustees hereafter appointed, may
at any time resign by giving written notice thereof to the Company.  Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument executed by authority of the Board of
Directors, a copy of which shall be delivered to the resigning Trustee and a
copy to the successor trustee.  If an instrument of acceptance by a successor
trustee shall not have been delivered to the Trustee within thirty (30) days
after the giving of such notice of resignation, the resigning Trustee may, or
any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor trustee.  Such
court may thereupon, after such notice, if any, as it may deem proper, appoint a
successor trustee.

          (c)  The Trustee may be removed at any time by an Act of the Holders
of not less than a majority in aggregate principal amount of the Outstanding
Securities, delivered to the Trustee and to the Company.

                                    - 78 -
<PAGE>
 
          (d)  If at any time:

               (1)  the Trustee shall fail to comply with the provisions of
          Trust Indenture Act Section 310(b) after written request therefor by
          the Company or by any Holder who has been a bona fide Holder of a
          Security for at least six months, or

               (2)  the Trustee shall cease to be eligible under Section 608
          hereof and shall fail to resign after written request therefor by the
          Company or by any Holder who has been a bona fide Holder of a Security
          for at least six months, or

               (3)  the Trustee shall become incapable of acting or shall be
          adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
          its property shall be appointed or any public officer shall take
          charge or control of the Trustee or of its property or affairs for the
          purpose of rehabilitation, conservation or liquidation,

then, in any case, (i) the Company by a Board Resolution may remove the Trustee,
or (ii) subject to Section 511 hereof, the Holder of any Security who has been a
bona fide Holder of a Security for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor trustee.  Such
court may thereupon, after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor trustee.  If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor trustee and supersede the successor trustee appointed by the Company.
If no successor trustee shall have been so appointed by the Company or the
Holders of the Securities and accepted appointment in the manner hereinafter
provided, the Holder of any Security who has been a bona fide Holder for at
least six months may, subject to Section 511 hereof, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor trustee.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor trustee by mailing written
notice of such event by first-class mail, postage prepaid, to the Holders of
Securities as their names and addresses appear in the Security Register.  Each
notice shall include the name of the successor trustee and the address of its
Corporate Trust Office or agent hereunder.

          Section 610.   Acceptance of Appointment by Successor.
                         -------------------------------------- 

          Every successor trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee as if originally named as Trustee hereunder;
but, nevertheless, on the written request of the Company or the successor
trustee, upon payment of its charges then unpaid, such retiring Trustee shall,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties and obligations.  Upon request of any
such successor trustee, the Company shall execute any and all instruments for
more fully and certainly vesting in and confirming to such successor trustee all
such rights and powers.  Any Trustee ceasing to act shall, nevertheless, retain
a prior claim upon all property or funds held or collected by such Trustee or
such successor trustee to secure any amounts then due such Trustee pursuant to
the provisions of Section 606 hereof.

          No successor trustee with respect to the Securities shall accept
appointment as provided in this Section 610 unless at the time of such
acceptance such successor trustee shall be eligible to act as trustee under the
provisions of Trust Indenture Act Section 310(a) and this Article Six and shall
have a combined capital and surplus of at least $50,000,000 or which shall be a
wholly owned subsidiary of a company that has a combined capital and surplus of
at least $50,000,000 and have a Corporate Trust Office or an agent selected in
accordance with Section 608 hereof.

          Upon acceptance of appointment by any successor trustee as provided in
this Section 610, the Company shall give notice thereof to the Holders of the
Securities, by mailing such notice to such Holders at their addresses as they
shall appear on the Security Register.  If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
609 hereof.  If the Company fails to give such notice within ten (10) days after
acceptance of

                                    - 80 -
<PAGE>
 
appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Company.

          Section 611.   Merger, Conversion, Consolidation or Succession to
                         --------------------------------------------------
Business.
-------- 

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be eligible under Trust Indenture Act Section
310(a) and this Article Six and shall have a combined capital and surplus of at
least $50,000,000 or which shall be a wholly owned subsidiary of a company that
has a combined capital and surplus of at least $50,000,000 and have a Corporate
Trust Office or an agent selected in accordance with Section 608 hereof without
the execution or filing of any paper or any further act on the part of any of
the parties hereto.

          In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have; provided that the right to adopt
                                                --------                        
the certificate of authentication of any predecessor Trustee or to authenticate
Securities in the name of any predecessor Trustee shall apply only to its
successor or successors by merger, conversion or consolidation.

                         ------------------------------------------------- 

          If and when the Trustee shall be or become a creditor of the Company
(or other obligor under the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).  A Trustee who has resigned or been
removed shall be subject to the Trust Indenture Act Section 311(a) to the extent
indicated therein.

          (a) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

          (b) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture, but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture but shall not be required to
     verify the contents thereof.

          (2) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

conform to any such supplemental indenture may be prepared and executed by the
Company and each Subsidiary Guarantor and authenticated and delivered by the

referred to in clauses (A) or (C) of this Section 1007 or contained in any
amendment to any agreement creating such Indebtedness, provided that the

the chief financial officer of the Company) than those provided for in such
Indebtedness being refinanced or amended, (E) encumbrances or restrictions
contained in any other Indebtedness permitted to be incurred subsequent to the
Closing Date pursuant to the provisions of Section 1008 hereof, provided that
any such encumbrances or restrictions are not materially more restrictive taken

Company) than the most restrictive of those provided for in the Indebtedness
referred to in clauses (A) or (C) of this Section 1007, (F) any such encumbrance
or restriction consisting of customary nonassignment provisions in leases
governing leasehold interests to the extent such provisions restrict the

          Section 1008.  Limitations on Indebtedness.
                         --------------------------- 

          The Company shall not, and shall not permit its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become liable with respect to or become responsible for the payment
of, contingently or otherwise ("incur"), any Indebtedness; provided, however,
                                                           --------  ------- 
that the Company, or a Restricted Subsidiary of the Company, may incur
Indebtedness if at the time of such incurrence and after giving pro forma effect
thereto, the Company's Consolidated Cash Flow

                                    - 96 -
<PAGE>
 
Coverage Ratio for the most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such Indebtedness is incurred, calculated on a pro forma basis as if such
Indebtedness was incurred on the first day of such four full fiscal quarter
period, would be at least 2.75 to 1.0.

          Notwithstanding the foregoing limitations, the limitations of this
Section 1008 shall not apply to the incurrence of Permitted Indebtedness.

          Section 1009.  Asset Sales.
                         ----------- 

          (a)  The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Sale (other than to the Company or other
Restricted Subsidiary) unless (i) the Company or such Restricted Subsidiary
receives consideration at the time of such Asset Sale at least equal to the Fair
Market Value of the assets sold or otherwise disposed of, and at least 80% of
the consideration received by the Company or such Restricted Subsidiary from
such Asset Sale is in the form of cash; provided however, that the amount of any
cash equivalent or note or other obligation received by the Company or such
Restricted Subsidiary from the transferee in any such transaction that is
converted within 90 days by the Company or such Restricted Subsidiary into cash
shall be deemed upon such conversion to be cash for purposes of this provision;
and (ii) the Net Proceeds received by the Company or such Restricted Subsidiary
from such Asset Sale are applied in accordance with the following paragraphs.
The provisions of this Section 1009 shall not apply to the transfer of assets or
property by Imperial West in connection with the Imperial West Joint Venture.

          (b) (i)  If all or a portion of the Net Proceeds of any Asset Sale are
not required to be applied to repay permanently any Senior Indebtedness of the
Company then outstanding as required by the terms thereof, or the Company
determines not to apply such Net Proceeds to the permanent prepayment of any
Senior Indebtedness outstanding or if no such Senior Indebtedness is then
outstanding, then the Company may within 365 days of the Asset Sale, invest the
Net Proceeds in the Company, or in one or more Restricted Subsidiaries in a
Related Business.  The amount of such Net Proceeds neither used to permanently
repay or prepay Senior Indebtedness nor used or invested as set forth in this
paragraph constitutes "Excess Proceeds."

         (ii)  When the aggregate amount of Excess Proceeds from one or more
     Asset Sales equals $5,000,000 or more, the Company shall apply 100% of such
     Excess Proceeds within 365 days subsequent to the consummation of the Asset
     Sale which resulted in the Excess Proceeds equalling $5,000,000 or more to
     the purchase of Securities tendered to the Company for

                                    - 97 -
<PAGE>
 
     purchase at a price (the "Asset Sale Purchase Price") equal to 100% of the
     principal amount thereof, plus accrued interest, if any, to the date of
     purchase pursuant to an offer to purchase made by the Company (an "Asset
     Sale Offer") with respect to the Securities.  Any Asset Sale Offer may
     include a pro rata offer under similar circumstances to purchase other
     Senior Indebtedness requiring a similar offer.

          (c)  Until such time as the Net Proceeds from any Asset Sale are
applied in accordance with this covenant, such Net Proceeds shall be segregated
from the other assets of the Company and its Subsidiaries and invested in cash
or Eligible Investments, except that the Company or any Restricted Subsidiary
may use any Net Proceeds pending the utilization thereof in the manner (and
within the time period) described above, to repay revolving loans (under the
Bank Credit Facility or otherwise) without a permanent reduction of the
commitment thereunder.

          (d)  Any Asset Sale Offer shall be made substantially in accordance
with the procedures described under Section 1109 hereof.  The Company shall
cause a notice of any Asset Sale Offer to be mailed to the Trustee and the
Holders at their registered addresses not less than 30 days nor more than 45
days before the purchase date.  Such notice to the Trustee shall set forth the
calculations used in determining the amount of Excess Proceeds to be applied to
the purchase of Securities.  Upon receiving notice of an Asset Sale Offer,
Holders may elect to tender their Securities in whole or in part in integral
multiples of $1,000 in exchange for cash.  To the extent that Holders properly
tender Securities in an amount exceeding the Asset Sale Offer, Securities of
tendering Holders shall be repurchased on a pro rata basis (based on amounts
tendered).

          (e)  In the event the Company is required to make an Asset Sale Offer
at a time when the Company is prohibited from making such Offer, the Company
shall, on or prior to the date that the Company is required to make an Asset
Sale Offer, (i) seek the consent of its lenders to repurchase Securities
pursuant to such Asset Sale Offer or (ii) refinance the Indebtedness that
prohibits such Asset Sale Offer; provided, however, that the failure to make or
                                 --------  -------                             
consummate the Asset Sale Offer as provided herein shall constitute an Event of
Default.

          (f)  The Company shall comply, to the extent applicable, with the
requirements of Rule 14e-1 under the Exchange Act, any other tender offer rules
under the Exchange Act and other securities laws or regulations in connection
with any offer to repurchase and the repurchase of the Securities as described
above.

          (g)  The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create or permit to exist or become effective any consensual
restriction (other than restrictions not more restrictive taken as a whole (as
determined in good faith by the chief financial officer of the Company) than
those in effect under Existing Indebtedness, and Indebtedness under the Bank
Credit Facility) that would materially impair the ability of the Company to
comply with the provisions of this Section 1009.

          Section 1010.  Limitation on Sale and Leaseback Transactions.
                         --------------------------------------------- 

          The Company shall not, and shall not permit any Restricted Subsidiary
to, enter into any Sale and Leaseback Transaction unless (i) at the time of the
occurrence of such transaction and after giving effect to such transaction and
(x) in the case of a Sale and Leaseback Transaction which is a Capitalized Lease
Obligation, giving effect to the Indebtedness in respect thereof, and (y) in the
case of any other Sale and Leaseback Transaction, giving effect to the
Attributable Indebtedness in respect thereof, the Company or such Restricted
Subsidiary could incur $1.00 of additional Indebtedness pursuant to the initial
paragraph under Section 1008 hereof, (ii) at the time of the occurrence of such
transaction, the Company or such Restricted Subsidiary could incur Indebtedness
secured by a Lien on property in a principal amount equal to or exceeding the
Attributable Indebtedness in respect of such Sale and Leaseback Transaction
pursuant to Section 1012 hereof, and (iii) the transfer of assets in such Sale
and Leaseback Transaction is permitted by, and the Company applies the proceeds
of such transaction in compliance with, Section 1009 hereof.

          Section 1011.  Limitation on Transactions With Affiliates.
                         ------------------------------------------ 

          (a)  The Company and its Restricted Subsidiaries shall not, directly
or indirectly, enter into any transaction or series of related transactions with
or for the benefit of any of their respective Affiliates other than with the
Company or any Restricted Subsidiaries, except on an arm's-length basis and if
(x)(i) in the case of any such transaction in which the aggregate rental value,
remuneration or other consideration (including the value of a loan), together
with the aggregate rental value, remuneration or other consideration (including
the value of a loan) of all such other transactions consummated in the year
during which such transaction is proposed to be consummated, exceeds $500,000,
the Company delivers Board Resolutions to the Trustee evidencing that the Board
of Directors and the Independent Directors that are disinterested each have (by
a majority vote) determined in good faith that the aggregate rental value,
remuneration or other consideration (including the value

                                    - 99 -
<PAGE>
 
of any loan) inuring to the benefit of such Affiliate from any such transaction
is not greater than that which would be charged to or extended by the Company or
its Subsidiaries, as the case may be, on an arm's-length basis for similar
properties, assets, rights, goods or services by or to a Person not affiliated
with the Company or its Subsidiaries, as the case may be, and (ii) in the case
of any such transaction in which the aggregate rental value, remuneration or
other consideration (including the value of any loan), together with the
aggregate rental value, remuneration or other consideration (including the value
of any loan) of all such other transactions consummated in the year during which
such transactions are proposed to be consummated, exceeds $5,000,000, the
Company delivers to the Trustee Board Resolutions as described in clause
(a)(x)(i) of this Section 1011 and an opinion of a nationally recognized
investment banking firm, unaffiliated with the Company and the Affiliate which
is party to such transaction, to the effect that the aggregate rental price,
remuneration or other consideration (including the value of a loan) inuring to
the benefit of such Affiliate from any such transaction is not greater than that
which would be charged to or extended by the Company or its Subsidiaries, as the
case may be, on an arm's-length basis for similar properties, assets, rights,
goods or services by or to a Person not affiliated with the Company or its
Subsidiaries, as the case may be, and (y) all such transactions referred to in
clauses (a)(x)(i) and (a)(x)(ii) of this Section 1011 are entered into in good
faith.  Any transaction required to be approved by Independent Directors
pursuant to the preceding paragraph must be approved by at least one such
Independent Director.

          (b)  The provisions of the preceding paragraph do not prohibit (i) any
Restricted Payment permitted to be paid pursuant to the provisions of Section
1006 hereof, (ii) any issuance of securities, or other payments, awards or
grants in cash, securities or otherwise pursuant to, or the funding of,
employment arrangements, stock options and stock ownership plans approved by the
Board of Directors, (iii) loans or advances to employees in the ordinary course
of business consistent with past practices, not to exceed $500,000 aggregate
principal amount outstanding at any time, (iv) the payment of fees and
compensation paid to, and indemnity provided on behalf of, officers, directors,
employees or consultants of the Company or any of its Subsidiaries, as

expenses to Interlaken Capital, Inc. for its financial advisory services to the
Company with respect to the Acquisition, the offering of the Securities and the
other financings entered into in connection therewith, and (vi) Existing
Affiliate Agreements, including amendments thereto entered into after the
Closing Date provided that the terms of any such amendment either (A) are not,
in the aggregate, less favorable to the Company than the terms of

                                    - 100 -
<PAGE>
 
such agreement prior to such amendment, or (B) if such terms are, in the
aggregate, less favorable to the Company, such amendment satisfies the
requirements of the preceding paragraph.

     surrender the Security, with the form entitled "Option of Holder to Elect
     Purchase" on the reverse of the Security completed, to the Paying Agent at

     surrendered, which unpurchased portion must be equal to $1,000 principal
     amount or an integral multiple thereof;

       (viii)  the instructions that Holders must follow in order to tender
     their Securities; and

     accepted; and

        (iii)  deliver to the Trustee the Securities so accepted together with

                                    - 104 -
<PAGE>
 
Company's written request return to the Company any cash that remains unclaimed,
together with interest or dividends, if any, thereon, held by them for the
payment of the Change of Control Purchase Price; provided, however, that (x) to
                                                 --------  -------             
the extent that the aggregate amount of cash deposited by the Company pursuant
to clause (ii) of paragraph (d) above exceeds the aggregate Change of Control
Purchase Price of the Securities or portions thereof to be purchased, then the
Trustee shall hold such excess for the Company and (y) unless otherwise directed
by the Company in writing, promptly after the Business Day following the Change
of Control Payment Date the Trustee shall return any such excess to the Company
together with interest, if any, thereon.

          (f)  The Company shall comply, to the extent applicable, with the

above.

          (g)  In the event a Change of Control occurs at a time when the
Company is prohibited from purchasing Securities, the Company shall, within
thirty (30) days following a Change of Control (i) seek the consent of its
lenders to the purchase of the Securities or (ii) refinance the Indebtedness
that prohibits such purchase; provided, however, that the failure to make or
                              --------  -------                             
consummate the Change of Control Offer shall constitute an Event of Default.

          (h)  The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create or permit to exist or become effective any restriction
(other than restrictions not more restrictive taken as a whole (as determined in
good faith by the chief financial officer of the Company) than those in effect
under Existing Indebtedness and Indebtedness under the Bank Credit Facility)
that would materially impair the ability of the Company to make a Change of
Control Offer to purchase the Securities or, if such Change of Control Offer is
made, to pay for the Securities tendered for purchase.

nothing herein shall prevent the Company or any of its Restricted Subsidiaries
from discontinuing any maintenance of any such properties if such discontinuance
is

                                    - 105 -

desirable in the conduct of the business of the Company and its Restricted

          Section 1018.  Money for Security Payments to Be Held in Trust.
                         ----------------------------------------------- 

          If the Company shall at any time act as its own Paying Agent, it
shall, on or before each due date of the principal of, premium, if any, or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Holders entitled thereto a sum sufficient to pay the principal, premium,
if any, or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided, and shall promptly notify

          (b)  give the Trustee notice of any Default by the Company or any

     making of any payment of principal, premium, if any, or interest;

          (c)  at any time during the continuance of any such Default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent; and

          (d)  acknowledge, accept and agree to comply in all aspects with the
     provisions of this Indenture relating to the duties, rights and
     disabilities of such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

promptly be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
                                --------  -------                          
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in the New York Times and The

Company that is a Subsidiary Guarantor transfers or causes to be transferred, in
one transaction or a series of related transactions, property or assets
(including,

                                    - 107 -
<PAGE>
 
without limitation, businesses, divisions, real property, assets or equipment)

the Trustee a supplemental indenture pursuant to which such Subsidiary or
Subsidiaries shall unconditionally guarantee, in accordance with Article
Thirteen hereof, all of the Company's obligations under the Indenture and the
Securities on the same terms as the other Subsidiary Guarantors, which Guarantee
shall rank pari passu with any Senior Indebtedness of such Subsidiary.  The
provisions of this Section 1019 shall not apply to the transfer of assets or
property by Imperial West in connection with the Imperial West Joint Venture.

such Guarantee is referred to as a "Subsidiary Guarantor."  Notwithstanding the
foregoing, any Guarantee by a Subsidiary of the Securities shall provide by its
terms that it shall be automatically and unconditionally released and discharged
upon any sale, exchange or transfer, to any Person not an Affiliate of the
Company, of all of the Company's Equity Interest in (or if such Subsidiary is
owned by a Restricted Subsidiary, of all of such Restricted Subsidiary's Equity
Interest in), or all or substantially all the assets of, such Subsidiary, which
is in compliance with this Indenture.

Indenture or (y) the ownership by directors of director's qualifying shares or

to pay the Redemption Price of and (except if the Redemption Date shall be an
Interest Payment Date) accrued interest on, all the Securities or portions
thereof which are to be redeemed on that date.  When the Redemption Date falls
on an Interest Payment Date, payments of interest due on such date are to be
paid as provided hereunder as if no such redemption were occurring.

          Section 1107.  Securities Payable on Redemption Date.
                         ------------------------------------- 

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such

                                    - 112 -

Security shall be paid by the Company at the Redemption Price together with
accrued interest to the Redemption Date; provided, however, that installments of
                                         --------  -------                      
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such on the relevant Regular Record Dates according to
the terms and the provisions of Section 309 hereof.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and premium, if any, shall,
until paid, bear interest from the Redemption Date at the rate borne by such
Security.

          Section 1108.  Securities Redeemed or Purchased in Part.
                         ---------------------------------------- 

          Any Security which is to be redeemed or purchased only in part shall
be surrendered to the Paying Agent at the office or agency maintained for such
purpose pursuant to Section 1002 hereof (with, if the Company, the Security
Registrar or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company, the Security
Registrar or the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to, and in exchange
for, the unredeemed portion of the principal of the Security so surrendered that
is not redeemed or purchased.

          Section 1109.  Asset Sale Offers.
                         ----------------- 

          In the event that the Company shall commence an Asset Sale Offer
pursuant to Section 1009 hereof, it shall follow the procedures specified below.

          The Asset Sale Offer shall remain open for twenty (20) Business Days
after the date on which such Asset Sale Offer is commenced (the "Commencement
Date") except to the extent required to be extended pursuant to applicable law
(as so extended, the "Asset Sale Offer Period").  No later than one Business Day
after the termination of the Asset Sale Offer Period (the "Asset Sale Purchase
Date"), the Company shall purchase the principal amount (the "Asset Sale Offer
Amount") of Securities required pursuant to Section 1009 hereof to be purchased
in such Asset Sale Offer or, if less than the Asset Sale Offer Amount has been
tendered, all Securities tendered in response to the Asset Sale Offer.

          If the Asset Sale Purchase Date is on or after a Regular Record Date
and on or before the related Interest Payment Date, any accrued interest shall
be paid to the Person in whose

                                    - 113 -
<PAGE>
 
name a Security is registered at the close of business on such Regular Record
Date, and no additional interest shall be payable to Holders who tender
Securities pursuant to the Asset Sale Offer.

          On the Commencement Date of any Asset Sale Offer, the Company shall
send or cause to be sent, by first class mail, a notice to each of the Holders,
with a copy to the Trustee.  Such notice, which shall govern the terms of the
Asset Sale Offer, shall contain all instructions and materials necessary to
enable the Holders to tender Securities pursuant to the Asset Sale Offer and
shall state:

          (1)  that the Asset Sale Offer is being made pursuant to Section 1009
     hereof and this Section 1109 and the length of time the Asset Sale Offer
     shall remain open;

          (2)  the Asset Sale Offer Amount, the Asset Sale Purchase Price and
     the Asset Sale Purchase Date;

          (3)  that any Security not tendered or accepted for payment shall
     continue to accrue interest in accordance with this Indenture;

          (4)  that, unless the Company defaults in the payment of the Asset
     Sale Purchase Price, all Securities accepted for payment pursuant to the
     Asset Sale Offer shall cease to accrue interest after the Asset Sale
     Purchase Date;

          (5)  that Holders electing to have Securities purchased pursuant to
     any Asset Sale Offer shall be required to surrender the Security, with the
     form entitled "Option of Holder to Elect Purchase" on the reverse of the
     Security completed, to the Company, a depositary, if appointed by the
     Company, or a Paying Agent at the address specified in the notice prior to
     the close of business on the Business Day preceding the Asset Sale Purchase
     Date;

          (6)  that Holders shall be entitled to withdraw their election if the
     Company, Depositary or Paying Agent, as the case may be, receives not later
     than the close of business on the Business Day preceding the termination of
     the Asset Sale Offer Period, a telegram, telex, facsimile transmission or
     letter setting forth the name of the Holder, the principal amount of the
     Security the Holder delivered for purchase, the certificate number on the
     Security and a statement that such Holder is withdrawing his election to
     have the Security purchased;

          (7)  that, if the aggregate principal amount of Securities surrendered
     by Holders exceeds the Asset Sale Offer Amount, the Company shall select
     the Securities to be

                                    - 114 -
<PAGE>
 
     purchased on a pro rata basis (with such adjustments as may be deemed
     appropriate by the Company so that only Securities in denominations of
     $1,000, or integral multiples thereof, shall be purchased); and

          (8)  that Holders whose Securities are purchased only in part shall be
     issued new Securities equal in principal amount to the unpurchased portion
     of the Securities surrendered, which unpurchased portion must be equal to
     $1,000 principal amount or an integral multiples thereof.

          On or before 10:00 a.m. New York City time on each Asset Sale Purchase
Date, the Company shall irrevocably deposit with the Trustee or Paying Agent in
immediately available funds the aggregate Asset Sale Purchase Price with respect
to a principal amount of Securities equal to the Asset Sale Offer Amount,
together with accrued interest thereon, to be held for payment in accordance
with the terms of this Section 1109.  On the Asset Sale Purchase Date, the
Company shall, to the extent lawful, (i) accept for payment, on a pro rata basis
to the extent necessary, an aggregate principal amount equal to the Asset Sale
Offer Amount of Securities tendered pursuant to the Asset Sale Offer, or if less
than the Asset Sale Offer Amount has been tendered, all Securities or portions
thereof tendered, (ii) deliver, or cause the Paying Agent or depositary, as the
case may be, to deliver to the Trustee Securities so accepted and (iii) deliver
to the Trustee an Officers' Certificate stating that such Securities or portions
thereof were accepted for payment by the Company in accordance with the terms of
this Section 1109.  The Company, a depositary or Paying Agent, as the case may
be, shall promptly (but in any case not later than two (2) Business Days after
the Asset Sale Purchase Date) mail or deliver to each tendering Holder an amount
equal to the Asset Sale Purchase Price with respect to the Securities tendered
by such Holder and accepted by the Company for purchase, and the Company shall
promptly issue a new Security, and the Trustee shall authenticate and mail or
deliver such new Security, to such Holder, equal in principal amount to any
unpurchased portion of such Holder's Securities surrendered.  Any Security not
accepted in the Asset Sale Offer shall be promptly mailed or delivered by the
Company to the Holder thereof.  The Company shall publicly announce in a
newspaper of general circulation the results of the Asset Sale Offer on the
Asset Sale Purchase Date.

          The Asset Sale Offer shall be made by the Company in compliance with
all applicable laws, including, without limitation, the requirements of Rule
14e-1 under the Exchange Act, any other tender offer rules under the Exchange
Act and all other applicable federal and state securities laws.

          Subject to applicable escheat laws, as provided in the Securities, the
Trustee and the Paying Agent shall return to the

                                    - 115 -

Company any cash that remains unclaimed, together with interest, if any,
thereon, held by them for the payment of the Asset Sale Purchase Price;
provided, however, that (x) to the extent that the aggregate amount of an Asset
--------  -------                                                              
Sale Offer exceeds the aggregate Asset Sale Purchase Price of the Securities or
portions thereof to be purchased, the Trustee shall hold such excess for the
Company and (y) unless otherwise directed by the Company in writing, promptly
after the Business Day following the Asset Sale Purchase Date the Trustee shall
return any such excess to the Company together with interest or dividends, if
any, thereon.

          Other than as specifically provided in this Section 1109, each
purchase pursuant to this Section 1109 shall be made pursuant to the provisions
of Sections 1101 through 1108 hereof.

time of any sum of money for the time being due or remaining unpaid to the
Trustee or the Holders.  Each Subsidiary Guarantor, jointly and severally,
covenants and agrees to comply with all obligations, covenants, agreements and
provisions applicable to it in this Indenture including those set forth in
Article Eight.  Without limiting the generality of the foregoing, each of the
Subsidiary Guarantors' liability shall extend to all amounts which constitute
part of the Indenture Obligations and would be owed by the Company under this

guarantees that the Indenture Obligations shall be paid to the Trustee without
set-off or counterclaim or other reduction whatsoever (whether for taxes,

terms or the rights of the Holders of the Securities.

          (d) Each Subsidiary Guarantor's liability to pay or perform or cause
the performance of the Indenture Obligations under this Guarantee shall arise
forthwith after demand for payment or performance by the Trustee has been given
to the Subsidiary Guarantors in the manner prescribed in Section 106 hereof.

          (e) Except as provided herein, the provisions of this Article Thirteen
cover all agreements between the parties hereto relative to this Guarantee and
none of the parties shall be bound by any representation, warranty or promise
made by any Person relative thereto which is not embodied herein; and it is
specifically acknowledged and agreed that this Guarantee has been delivered by
each Subsidiary Guarantor free of any conditions whatsoever and that no
representations, warranties or promises have been made to any Subsidiary
Guarantor affecting its liabilities hereunder, and that the Trustee shall not be
bound by any representations, warranties or promises now or at any time
hereafter made by the Company to any Subsidiary Guarantor.

legal existence, is or becomes under no legal obligation to discharge the
Indenture Obligations owing to the Trustee or the Holders by the Company or if
any of the Indenture Obligations owing by the Company to the Trustee or the
Holders become irrecoverable from the Company by operation of law or for any
reason whatsoever, this Guarantee and the covenants, agreements and obligations
of the Subsidiary Guarantors contained in this Article Thirteen shall
nevertheless be binding upon the Subsidiary Guarantors, as principal debtor,
until such time as all such Indenture Obligations have been paid in full to the
Trustee and all Indenture Obligations owing to the Trustee or the Holders by the
Company have been discharged, or such earlier time as Section 402 hereof shall
apply to the Securities and the Subsidiary Guarantors shall be responsible for
the payment thereof to the Trustee or the Holders upon demand.

          Section 1307.  Fraudulent Conveyance; Subrogation.
                         ---------------------------------- 

          (a) Any term or provision of this Guarantee to the contrary
notwithstanding, the aggregate amount of the Indenture Obligations guaranteed
hereunder shall be reduced to the extent necessary to prevent this Guarantee
from violating or becoming voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting the rights of
creditors generally.

          (b) Each Subsidiary Guarantor hereby waives until repayment in full of
the Indenture Obligations and except as provided in Section 1309, all rights of
subrogation or contribution, whether arising by contract or operation of law
(including, without limitation, any such right arising under federal bankruptcy
law) or otherwise by reason of any payment by it pursuant to the provisions of
this Article Thirteen.

          Section 1308.  Guarantee Is in Addition to Other Security.
                         ------------------------------------------ 

          This Guarantee shall be in addition to and not in substitution for any
other guarantees or other security which the Trustee may now or hereafter hold
in respect of the Indenture Obligations owing to the Trustee or the Holders by
the Company and (except as may be required by law) the Trustee shall be under no
obligation to marshal in favor of each of the Subsidiary Guarantors any other
guarantees or other security or any moneys or other assets which the Trustee may
be entitled to receive or upon which the Trustee or the Holders may have a
claim.

          Section 1309.  Contribution.
                         ------------ 

          In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the
                                                        ----- --             
event any payment or distribution is made

                                    - 123 -
<PAGE>
 
by any Subsidiary Guarantor (a "Funding Subsidiary Guarantor") under its
Guarantee, such Funding Subsidiary Guarantor shall be entitled to a contribution
from all other Subsidiary Guarantors in a pro rata amount based on the "Adjusted
                                          --- ----                              
Net Assets" (as defined below) of each Subsidiary Guarantor (including the
Funding Subsidiary Guarantor) for all payments, damages and expenses incurred by
that Funding Subsidiary Guarantor in discharging the Company's obligations with
respect to the Securities or any other Subsidiary Guarantor's obligation with
respect to its Guarantee.  "Adjusted Net Assets" means, with respect to any
Subsidiary Guarantor, at any date, the lesser of the amount by which (x) the
fair value of the property of such Subsidiary Guarantor exceeds the total amount
of liabilities, including, without limitation, contingent liabilities (after
giving effect to all other fixed and contingent liabilities incurred or assumed
on such date), but excluding liabilities under the Guarantee, of such Subsidiary
Guarantor at such date and (y) the present fair salable value of assets of such
Subsidiary Guarantor at such date exceeds the amount that shall be required to
pay the probable liability of such Subsidiary Guarantor on its debts (after
giving effect to all other fixed and contingent liabilities incurred or assumed
on such date), excluding debt in respect of its Guarantee, as they become
absolute and matured.

          Section 1310.  No Bar to Further Actions.
                         ------------------------- 

          Except as provided by law, no action or proceeding brought or
instituted under Article Thirteen and this Guarantee and no recovery or judgment
in pursuance thereof shall be a bar or defense to any further action or
proceeding which may be brought under Article Thirteen and this Guarantee by
reason of any further default or defaults under Article Thirteen and this
Guarantee or in the payment of any of the Indenture Obligations owing by the
Company.

          Section 1311.  Failure to Exercise Rights Shall Not Operate as a
                         -------------------------------------------------
Waiver.
------ 

          No failure to exercise and no delay in exercising, on the part of the
Trustee or the Holders, any right, power, privilege or remedy under this Article
Thirteen and this Guarantee shall operate as a waiver thereof, nor shall any
single or partial exercise of any rights, power, privilege or remedy preclude
any other or further exercise thereof, or the exercise of any other rights,
powers, privileges or remedies.  The rights and remedies herein provided for are
cumulative and not exclusive of any rights or remedies provided in law or
equity.

          Section 1312.  Trustee's Duties; Notice to Trustee.
                         ----------------------------------- 

          (a) Any provision in this Article Thirteen or elsewhere in this
Indenture allowing the Trustee to request any information or to take any action
authorized by, or on behalf of any Subsidiary Guarantor, shall be subject to
Section 602(d) and shall be permissive and shall not be obligatory on the
Trustee except as the Holders may direct in accordance with the provisions of
this Indenture or where the failure of the Trustee to request any such
information or to take any such action arises from the Trustee's gross
negligence, bad faith or willful misconduct.

          (b) The Trustee shall not be required to inquire into the existence,
powers or capacities of the Company, any Subsidiary Guarantor or the officers,
directors or agents acting or purporting to act on their respective behalf.

          Section 1313.  Successors and Assigns.
                         ---------------------- 

          All terms, agreements and conditions of this Article Thirteen shall
extend to and be binding upon each Subsidiary Guarantor and its successors and
permitted assigns and shall enure to the benefit of and may be enforced by the
Trustee and its successors and assigns; provided, however, that the Subsidiary
                                        --------  -------                     
Guarantors may not assign any of their rights or obligations hereunder other
than in accordance with Article Eight.

          Section 1314.  Release of Guarantee.
                         -------------------- 

          Concurrently with the payment in full of all of the Indenture
Obligations, the Subsidiary Guarantors shall be released from and relieved of
their obligations under this Article Thirteen.  Upon the delivery by the Company
to the Trustee of an Officers' Certificate and, if requested by the Trustee, an
Opinion of Counsel to the effect that the transaction giving rise to the release
of this Guarantee was made by the Company in accordance with the provisions of
this Indenture and the Securities, the Trustee shall execute any documents
reasonably required in order to evidence the release of the Subsidiary
Guarantors from their obligations under this Guarantee.  If any of the Indenture
Obligations are revived and reinstated after the termination of this Guarantee,
then all of the obligations of the Subsidiary Guarantors under this Guarantee
shall be revived and reinstated as if this Guarantee had not been terminated
until such time as the Indenture Obligations are paid in full, and each
Subsidiary Guarantor shall enter into an amendment to this Guarantee, reasonably
satisfactory to the Trustee, evidencing such revival and reinstatement.

                                    - 125 -
<PAGE>
 
          This Guarantee shall terminate with respect to each Subsidiary
Guarantor and shall be automatically and unconditionally released and discharged
as provided in Section 1019(b) hereof.

          Section 1315.  Execution of Guarantee.
                         ---------------------- 

          To evidence the Guarantee, each Subsidiary Guarantor hereby agrees to
execute the guarantee substantially in the form set forth in Section 205 hereof,
to be endorsed on each Security authenticated and delivered by the Trustee and
that this Indenture shall be executed on behalf of each Subsidiary Guarantor by
its Chairman of the Board, its President, or one of its Vice Presidents, under
its corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries.  The signature of any of these officers on the Securities
may be manual or facsimile.

          If an officer whose signature is on this Indenture no longer holds
that office at the time the Trustee authenticates a Security on which a
Guarantee is endorsed, such Guarantee shall be valid nevertheless.

          Section 1316.  Payment Permitted by Each of the Subsidiary Guarantors
                         ------------------------------------------------------
if No Default.
------------- 

          Nothing contained in this Article, elsewhere in this Indenture or in
any of the Securities shall affect the obligation of any Subsidiary Guarantor to
make, or prevent any Subsidiary Guarantor from making at any time, payments
pursuant to the Securities.

          Section 1317.  Notice to Trustee by Each of the Subsidiary Guarantors.
                         ------------------------------------------------------
Each Subsidiary Guarantor shall give prompt written notice to the Trustee of any
fact known to such Subsidiary Guarantor which would prohibit the making of any
payment to or by the Trustee in respect of the Guarantee.  Notwithstanding the
provisions of this Article or any provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment to or by the Trustee in respect of the Securities,
unless and until the Trustee shall have received written notice thereof from any
Subsidiary Guarantor or any trustee, fiduciary or agent therefor; and, prior to
the receipt of any such written notice, the Trustee shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the
                                             --------  -------             
Trustee shall not have received the notice provided for in this Section at least
three (3) Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of, premium, if any, or interest on any Security or any
other Indenture Obligations), then, anything herein contained

                                    - 126 -
<PAGE>
 
to the contrary notwithstanding, the Trustee shall have full power and authority
to receive such money and to apply the same to the purpose for which such money
was received and shall not be affected by any notice to the contrary which may
be received by it after such date; nor shall the Trustee be charged with
knowledge of the curing of any such default or the elimination of the act or
condition preventing any such payment unless and until the Trustee shall have
received an Officers' Certificate to such effect.

          Section 1318.  Article Applicable to Paying Agents.
                         ----------------------------------- 

          In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting under this Indenture, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; provided,
                                                                      -------- 
however, that this Section 1318 shall not apply to the Company or any Affiliate
-------                                                                        
of the Company if it or such Affiliate acts as Paying Agent.

          Section 1319.  No Suspension of Remedies.
                         ------------------------- 

          Nothing contained in this Article shall limit the right of the Trustee
or the Holders of Securities to take any action to accelerate the maturity of
the Securities pursuant to the provisions described under Article Five and as
set forth in this Indenture or to pursue any rights or remedies hereunder or
under applicable law.

be duly executed, all as of the day and year first above written.

Dear Sirs:

     otherwise transfer such Securities prior to the date which is three years
     after the later of the date of original issue and the last date on which

             2.1.1  Revolving Loans.
                    --------------- 

          (a) Subject to the terms and conditions of this Agreement and the
Related Agreements, and in reliance upon the warranties and representations of
Borrower set forth herein and the warranties and representations of Borrower and
each other Obligor set forth in the Related Agreements, each Lender, severally
and not jointly, agrees to make its Pro Rata Share of such loans or advances
(individually each a "Revolving Loan" and collectively the "Revolving Loans")
from time to time before the Termination Date to Borrower as Borrower may from
time to time request; provided, that Agent may, but shall not be obligated to,
make such Revolving Loans to Borrower on behalf of Lenders as a
"Disproportionate Advance" (as defined below); provided further, that, except as
provided in Section 2.8, the aggregate outstanding principal amount of the
            -----------                                                   
Revolving Loans made by or on behalf of Lenders shall not at any time exceed the
Revolving Loan Availability.  Revolving Loans made by or on behalf of Lenders
may be repaid and, subject to the terms and conditions hereof, reborrowed to but
not including the Termination Date unless the Credit extended under this
Agreement is otherwise terminated as provided in this Agreement.  No Lender
shall be obligated at any time to make available to Borrower its Pro Rata Share
of any requested Revolving Loan if such amount, plus its Pro Rata Share of all
Revolving Loans then outstanding, would exceed such Lender's Maximum Loan Amount
at such time.  No Lender shall be obligated to make available its Pro Rata Share
of any Revolving Loans during the occurrence of any Event of Default or
Unmatured Event of Default; provided that notwithstanding the foregoing or
anything contained herein to the contrary, regardless of whether an
Event of Default or an Unmatured Event of Default exists, each Lender shall, at
the request of Agent, continue to be obligated to make its Pro Rata Share of the
Revolving Loans available to

Borrower for a period of up to five (5) Banking Days, but in any event, no
Lender shall be obligated at any time to make available to Borrower its Pro Rata
Share of any such requested Revolving Loan if such amount, plus its Pro Rata
Share of all Revolving Loans then outstanding, would exceed such Lender's
Maximum Loan Amount at such time. Neither Agent nor any Lender shall be
responsible for any failure by any other Lender to perform its obligations to
make advances hereunder, and the failure of any Lender to make its Pro Rata
Share of any advance hereunder shall not relieve any other Lender of its
obligation, if any, to make its Pro Rata Share of Loans hereunder, nor require
such other Lender to make more than its Pro Rata Share of any Loans hereunder.
If Borrower makes a request for a Revolving Loan as provided herein, or if Agent
desires to make a Revolving Loan pursuant to any other provision of this
Agreement or any Related Agreement that permits Agent to advance Revolving Loans
to Borrower, Agent, at its option and in its sole and absolute discretion, shall
do either of the following:

             (i) Advance the amount of the proposed Revolving Loan to Borrower
     disproportionately (a "Disproportionate Advance") out of Agent's own funds
     on behalf of Lenders, and request settlement in accordance with Section
                                                                     -------
     2.15, such that upon such settlement, each Lender's share of the
     ----                                                            
     outstanding Revolving Loans (including, without limitation, the amount of
     any Disproportionate Advance) equals its Pro Rata Share and such
     Disproportionate Advance shall be deemed to be repaid; or

             (ii) Notify each Lender and Borrower by telecopy or other similar
     form of teletransmission of the proposed advance on the same day Agent is
     notified by Borrower of Borrower's request for an advance hereunder or the
     same day Agent desires to make a Revolving Loan for the benefit of Borrower
     (to the extent permitted hereunder or under any Related Agreement).  Each
     Lender shall remit, to the Demand Deposit Account, on or prior to twelve
     o'clock noon, Chicago time, on the business day immediately succeeding the
     date of such notification, immediately available funds in an amount equal
     to such Lender's Pro Rata Share of such proposed advance.

If and to the extent that a Lender does not settle with Agent as required under
clause (i), Borrower agrees to repay to Agent forthwith on demand such amount
----------                                                                   
required to be paid by such Lender to Agent, together with interest thereon, for
each day from the date such amount is made available to Borrower until the date
such amount is repaid to Agent, at the interest rate 

                                     -23-
<PAGE>
 
applicable at such time for such Revolving Loans; provided, that Borrower's
obligation to repay such advance to Agent shall not relieve each Lender of its
liability to Agent or Borrower for failure to settle as provided in clause (i).
                                                                    ---------- 

          (b) In the event the aggregate outstanding principal balance of the
Revolving Loans exceeds the Revolving Loan Availability, Borrower shall, unless
Agent permits such Over Advance as provided in Section 2.8 or Requisite Lenders
                                               -----------                     
shall otherwise consent, without notice or demand of any kind, immediately make
such repayments of the Revolving Loans or take such other actions as shall be
necessary to eliminate such excess.

          (c) All Revolving Loans hereunder shall be paid by Borrower on the
Termination Date, unless payable sooner pursuant to the provisions of this
Agreement, but may, at Borrower's election, be repaid in whole or in part at any
time prior to such date without premium or penalty (other than as expressly
provided in Section 3.4 of Supplement A with respect to LIBOR Rate Loans repaid
            -----------    ------------

premium or penalty (other than as expressly provided in Section 3.4 of

of the Revolving Loans, together with (a) all accrued and unpaid interest on the
Liabilities, (b) all other outstanding Liabilities and (c) cash in the amount
of, or adequate (in Agent's determination) cash collateral for, the Letter of
Credit Obligations.  Borrower may not permanently reduce the Revolving Credit
Amount except (i) in connection with the prepayment in full of all of the
Liabilities or (ii) if, after giving effect to such reduction, the Revolving
Credit Amount equals or exceeds the amount of the Loans plus the Letter of
Credit Obligations then outstanding.

          2.1.3  Maximum Outstanding Liabilities.  Notwithstanding any other
                 -------------------------------                            
provision of this Agreement, the aggregate outstanding principal balance of the
Loans plus Letter of Credit Obligations shall not exceed the Revolving Credit
Amount; provided, however, that the foregoing shall not limit the right of Agent
        --------  -------

Agreement or any Related Agreement that permits Agent to advance Revolving Loans

                                     -24-

foregoing provisions shall be deemed to be a Revolving Loan made by Agent on
behalf of Lenders.

             2.2  Letters of Credit.
                  ----------------- 

          (a) In addition to Loans made pursuant to Section 2.1, Agent will,
                                                    -----------             
upon receipt of duly executed Applications and such other documents, instruments
and/or agreements as Agent may require, request, on Borrower's behalf, that
Issuing Bank issue Letters of Credit on such terms as are satisfactory to Agent
and Issuing Bank, provided, however that no Letter of Credit will be issued if,
                  --------  -------
before or after taking such Letter of Credit into account, (i) the Letter of
Credit Obligations exceed $6,000,000 or (ii) the Letter of Credit Obligations
exceeds the lesser of (A) the Revolving Credit Amount minus the outstanding
principal balance of the Revolving Loans and (B) the Borrowing Base minus the
outstanding principal balance of the Revolving Loans. If such excess shall at
any time exist, Borrower shall, unless Requisite Lenders shall otherwise
consent, promptly make such payments as are necessary to eliminate such excess
or shall promptly post cash collateral in the amount of such excess. No Letter
of Credit shall have an expiry date after the Termination Date.

          (b) Borrower agrees to pay to Issuing Bank, on demand, Issuing Bank's
standard issuance, negotiation and administrative operating fees and charges in
effect from time to time for issuing and administering any Letters of Credit and
if not so paid, each Lender shall, without regard to any other provision of this
Agreement or any other Related Agreement, any defense that Borrower may have to
its obligation to pay Issuing Bank in connection with such fees and charges or
any defense that any Lender may have in connection with the participation
described in Section 2.2(e) in connection with any Letter of Credit or L/C
             --------------                                               
Draft, pay Issuing Bank for such Lender's Pro Rata Share of such fees and
charges, and any payments so made by Lenders to Issuing Bank shall be deemed to
be Revolving Loans.  Each Lender (other than a Lender that is Issuing Bank)
acknowledges and agrees that it shall not be entitled to any of the fees and
charges of Issuing Bank.  Borrower further agrees to pay Agent, for the benefit
of itself and Lenders, a commission equal to one and one-half percent (1.5%) per
annum (calculated on the basis of a year consisting of three hundred sixty (360)
days and paid for actual days elapsed) of the daily average of the undrawn
amount of each Letter of Credit and on each L/C Draft accepted (but not yet
paid) in connection therewith.  Such Letter of Credit commissions shall be paid
in arrears on the last day of each month thereafter.  Agent may provide for the
payment of any fees, charges or commissions due hereunder by advancing the
amount thereof to Borrower as a Revolving Loan.  At all times 

                                     -25-
<PAGE>
 
that any Default Rate is being charged under this Agreement, the Letter of
Credit commission shall be equal to the otherwise applicable commission plus two
percent (2%) per annum.

          (c) Subject to the remaining sentences of this clause (c), Borrower
                                                         ----------          
agrees to reimburse Issuing Bank, on demand, for each payment made by Issuing
Bank under or pursuant to any Letter of Credit or L/C Draft and if not so
reimbursed, each Lender shall, without regard to any other provision of this
Agreement or any other Related Agreement, any defense that Borrower may have to
its obligation to reimburse Issuing Bank in connection with such payment or any
defense that any Lender may have in connection with the participation described
in Section 2.2(e) in connection with any Letter of Credit or L/C Draft,
   --------------                                                      
reimburse Issuing Bank for such Lender's Pro Rata Share of such payment, and any
payments so made by Lenders to Issuing Bank shall be deemed to be Revolving
Loans. Agent and Lenders agree that so long as there is sufficient Revolving
Loan Availability and provided that no Event of Default is then in existence or
would be caused thereby, Agent will provide for the payment of any reimbursement
obligations and any interest accrued thereon by advancing the amount thereof to
Borrower as a Revolving Loan as soon as reasonably practicable. Prior to such
advance, the amount of such reimbursement obligations shall bear interest at the
then applicable Reference Rate. Agent shall have the option, pursuant to Section
                                                                         -------
2.8, to so provide for such payments even if there is not sufficient Revolving
---
Loan Availability or if an Event of Default is then in existence or would be
caused thereby and such amounts will bear interest at the rate set forth in
Section 2.8.  In the event a Letter of Credit or L/C Draft is not reimbursed
-----------                                                                 
from a Revolving Loan as provided herein, Borrower agrees to pay Agent, for the
benefit of itself and Lenders, on demand, interest at the Default Rate on any
amounts paid by Issuing Bank in respect of a Letter of Credit or an L/C Draft
until the reimbursement of Issuing Bank by Borrower of such payment.

          (d) Notwithstanding anything to the contrary herein or in any
Application, upon the occurrence of an Event of Default, an amount equal to the
aggregate amount of the outstanding Letter of Credit Obligations shall, at
Agent's option and without demand upon or further notice to Borrower, be deemed
(as between Lenders and Borrower) to have been paid or disbursed by Agent under
the Letters of Credit and accepted L/C Drafts (notwithstanding that such amounts
may not in fact have been so paid or disbursed), and a Revolving Loan to
Borrower in the amount of such Letter of Credit Obligations to have been made
and accepted, which Loan shall be immediately due and payable.  In lieu of the
foregoing, at the election of Agent at any time after an Event of Default,
Borrower shall, upon Agent's demand, deliver 

                                     -26-

to Agent cash collateral equal to the aggregate Letter of Credit Obligations.
Any such cash collateral and/or any amounts received by Agent in payment of the
Loan made pursuant to this paragraph (d) shall be held by Agent, for the benefit
                           -------------
of itself and Lenders, in the Assignee Deposit Account or a separate account
appropriately designated as a cash collateral account in relation to this
Agreement and the Letters of Credit and shall be retained by Agent, for the
benefit of itself and Lenders, as collateral security in respect of, first, the
Liabilities under or in connection with the Letters of Credit and L/C Drafts and
then, all other Liabilities. Such amounts shall not be used by Agent to pay any
amounts drawn or paid under or pursuant to any Letter of Credit or L/C Draft,
but may be applied to reimburse Issuing Bank for drawings or payments under or
pursuant to Letters of Credit or L/C Drafts which Issuing Bank has paid, or if
no such reimbursement is required, to payment of such other Liabilities as Agent
shall determine. Any amounts remaining in any cash collateral account
established pursuant to this paragraph (d) following payment in full of all
                             -------------
Liabilities shall be returned to Borrower.

          (e) Immediately upon the issuance of a Letter of Credit in accordance
with this Agreement, each Lender shall be deemed to have irrevocably and
unconditionally purchased and received from Issuing Bank, without recourse or
warranty, an undivided interest and participation therein to the extent of such
Lender's Pro Rata Share (including without limitation, all obligations of
Borrower with respect thereto).  Borrower hereby indemnifies each of Agent and
each Lender against any and all liability and expense it may incur in connection
with any Letter of Credit or L/C Draft and agrees to reimburse each of Agent and
each Lender for any payment made by Agent or any Lender to Issuing Bank, except
for any liability incurred or payment made as a result of Agent's or such
Lender's gross negligence or willful misconduct.

          2.3  Loan Account; Demand Deposit Account.  Agent shall establish or

(each a "Loan Account") to evidence Loans made to Borrower.  Agent or Lenders,
as appropriate, will credit or cause to be credited to a commercial account
("Demand Deposit Account") maintained by Borrower at BAI's 231 South LaSalle
Street, Chicago, Illinois office the amount of any sums advanced as Loans
hereunder, which shall be disbursed at Borrower's direction.  Any amounts
advanced as Loans hereunder which are credited to Borrower's Demand Deposit
Account, together with any other amounts advanced to Borrower as a Loan pursuant
to this Agreement, will be debited to the applicable Loan Account and result in
an increase in the

          2.4.1  Interest.  The unpaid principal amount of each Revolving Loan
                 --------                                                     
hereunder shall bear interest until maturity at the rate or rates applicable to
Revolving Loans indicated in Supplement A hereto.  If any Revolving Loan or
                             ------------                                  
portion thereof is not paid when due, whether by acceleration or otherwise, the
entire unpaid principal amount of the Revolving Loans shall bear interest
thereafter until such amount is paid in full at the Default Rate applicable to
Revolving Loans indicated in Supplement A hereto.  Until maturity, interest on
                             ------------                                     
the Revolving Loans shall be paid by Borrower on the date(s) indicated in
                                                                         
Supplement A, and at such maturity.  After maturity, whether by acceleration or

otherwise, accrued interest shall be payable on demand.

          2.4.2    Nonuse Fee.  Borrower agrees to pay to Agent, for the benefit
                   ----------                                                   
of itself and Lenders, a fee equal to one-half of one percent (0.5%) per annum
on the daily average amount by which the Revolving Credit Amount exceeds the
outstanding principal balance of the Revolving Loans plus the Letter of Credit
Obligations; provided, however, that the amount of such fee payable in a given
             --------                                                         
month shall be reduced by an amount equal to (i) one-half of one percent (0.5%)
per annum, times (ii) the amount of the daily average decrease in the Borrowing
Base during the preceding month resulting from all reductions in the Inventory
Percentage since the Closing Date, as described in Supplement A. The fee
                                                   ------------
provided for in this Section 2.4.2 shall be payable monthly in arrears on the

last day of each month commencing April 30, 1995, and on the date the Revolving
Credit terminates for the period then ended.

          2.4.3  Method of Calculating Interest and Fees.  Interest on the
                 ---------------------------------------                  
unpaid principal amount of each Loan shall accrue from and including the date
such Loan is made to, but not including, the date such Loan is paid.  Interest
and any fees shall be calculated on the basis of a year consisting of three
hundred sixty (360) days and paid for actual days elapsed.

          2.4.4  Payment of Interest and Fees.  Agent may provide for the
                 ----------------------------                            
payment of any unpaid accrued interest and any fees by charging the Demand
Deposit Account or any bank account maintained by Borrower with Agent or by
advancing the amount thereof to Borrower as a Revolving Loan.

                  ------------------------------------------------------
Information.
----------- 

          (a) Loans shall be requested in writing or by telephone, except for
Overdraft Loans and Revolving Loans made pursuant to the provisions of Section
                                                                       -------
2.2(b), 2.2(c), 2.2(d), 2.4.4, 2.10(c), 3.2(c), 5.5, 5.6, 7.4, 12.3, or 12.4 or
------  ------  ------  -----  -------  ------  ---  ---  ---  ----     ----   
any other provision of this Agreement or any Related Agreement that permits
Agent to advance Revolving Loans to Borrower.

          (b) In the event that Borrower shall at any time, or from time to
time, (i) make a request for a Loan hereunder or (ii) be deemed to have
requested an Overdraft Loan, Borrower agrees to forthwith provide Agent and
Lenders with such information, at such frequency and in such format, as is
reasonably required by Agent, such information to be current as of the time of
such request.

          (c) Borrower further agrees to provide to Agent and Lenders a current
Borrowing Base Certificate on the 15th day of each month for the preceding month
and at such other times as Agent may request.  Such Borrowing Base Certificate
shall be in substantially the same form as that attached hereto as Exhibit A,
                                                                   --------- 
executed and certified as accurate by such officers or employees of Borrower as
Borrower designates from time to time in writing to Agent pursuant to duly
adopted resolutions of Borrower's Board of Directors authorizing such action.

          (d) Borrower may request, telephonically or by written authorization,
the disbursement of Revolving Loans by Agent or Lenders, as appropriate.
Borrower shall provide Agent with documentation satisfactory to Agent indicating
the names of those employees of Borrower authorized by Borrower to sign
Borrowing Base Certificates and/or to make telephonic requests for Loans and
Letters of Credit, and/or to authorize disbursement of the proceeds
of Loans by wire transfer or otherwise, and Agent and Lenders shall be entitled
to rely upon such documentation until notified in writing by Borrower of any
change(s) in the names of the employees so authorized.  Agent and Lenders shall
be entitled to act on the instructions of anyone identifying himself as one of
the persons authorized to request Loans and Letters of Credit, or disbursements
of Loan proceeds by telephone and Borrower shall be bound thereby in the same
manner as if the person were actually so authorized.  Borrower agrees to
indemnify and hold each of Agent and each Lender harmless from any and all
claims, damages, liabilities, losses, costs and expenses (including Attorneys'
Fees) which may arise or be created by the acceptance of instructions for making
or paying Loans in writing or by telephone.  Each such request must be received
by Agent no 

                                     -29-
<PAGE>
 
later than 11:00 a.m. (Chicago time) on the date on which such Revolving Loan is
requested to be made.

          2.6  Statements.  All Loans and payments hereunder shall be recorded
               ----------                                                     
on Agent's books, which shall be rebuttably presumptive evidence of the amount
of such Loans outstanding at any time hereunder.  Agent will account monthly as
to all Loans and payments hereunder and, absent demonstrable error, each monthly
accounting will be fully binding on Borrower unless, within thirty (30) days of
Borrower's receipt thereof, Borrower shall provide Agent with a specific listing
of exceptions.  Notwithstanding any term or condition of this Agreement to the
contrary, however, the failure of Agent to record the date and amount of any
Loan hereunder shall not limit or otherwise affect the obligation of Borrower to
repay any such Loan.

          2.7  Overdraft Loans.  Agent, in its sole and absolute discretion, and
               ---------------                                                  
subject to the terms hereof, may make a Revolving Loan to Borrower in an amount
equal to the amount of any overdraft which may from time to time exist with
respect to the Demand Deposit Account or any bank account which Borrower may now
or hereafter have with Agent.  The existence of any such overdraft shall be
deemed to be a request by Borrower for such Loan.  Borrower acknowledges that
Agent is under no duty or obligation to make any Loan to Borrower to cover any
overdraft.  Borrower further agrees that if the making of a Loan to cover any
Overdraft would result in an Over Advance, such overdraft shall constitute a
separate Loan under this Agreement (an "Overdraft Loan"), which shall bear, from
the date on which the overdraft occurred until paid, interest in an amount equal
to the greater of one hundred thirty percent (130%) of the highest rate of
interest then actually being charged for Revolving Loans (other than Overdraft
Loans) made hereunder, and $50 per day.  If Agent, in its sole and absolute
discretion, decides not to make a Loan to cover part or all of any overdraft,
Agent may return any check(s) which created such overdraft.

          2.8  Over Advances.  If the aggregate outstanding Revolving Loans and
               -------------                                                   
Letter of Credit Obligations exceed Revolving Loan Availability (such excess
Liabilities are herein referred to as "Over Advances"), Agent, in its sole and
absolute discretion, may, for a period of five (5) Banking Days, to the extent
such Over Advance arises as a result of a reduction in the Borrowing Base,
permit such Over Advance to exist without the consent of any Lender (but subject
to Section 2.1.1(a)) and continue to make Revolving Loans on behalf of Lenders,
   ----------------
and after the expiration of such five (5) Banking Day period, no such event or
occurrence shall cause or constitute a waiver by any Lender of its right to
refuse to make any further Revolving Loans at any time that an Over Advance
exists or would result therefrom; provided, that

                                     -30-
<PAGE>
 
Agent may not (i) make Revolving Loans on behalf of Lenders under this Section
                                                                       -------
2.8 to the extent such Revolving Loans would cause a Lender's Pro Rata Share of
---
the Revolving Loans to exceed such Lender's Maximum Loan Amount or (ii) make
Revolving Loans on behalf of Lenders under this Section 2.8 to the extent such
                                                -----------
Revolving Loans would cause the then outstanding Revolving Loans and Letter of
Credit Obligations to exceed the sum of $1,000,000 and the amount of the
outstanding Revolving Loans and Letter of Credit Obligations as of the date
Agent became aware of the Over Advance. During any period in which an Over
Advance exists, the amount of Over Advances shall bear interest at a rate equal
to one hundred thirty percent (130%) of the highest rate of interest then
actually being charged for Revolving Loans made hereunder.

          2.9  All Loans One Obligation.  The Revolving Loans and all other
               ------------------------                                    
Loans under this Agreement shall constitute one Loan, and all Indebtedness and
other Liabilities of Borrower under this Agreement and any of the Related
Agreements shall constitute one general obligation secured by Agent's Lien, for
the benefit of itself and Lenders, on all of the Collateral and by all other
Liens heretofore, now, or at any time or times hereafter granted by Borrower or
any other Obligor to Agent, for the benefit of itself and Lenders.  Borrower
agrees that all of the rights of Agent and Lenders set forth in this Agreement
shall apply to any modification of or supplement to this Agreement, any
Supplements or Exhibits hereto, and the Related Agreements, unless otherwise
agreed in writing.

             2.10  Making of Payments; Application of Collections; Charging of
                   -----------------------------------------------------------
Accounts.
-------- 

          (a) All payments hereunder (including payment of Letter of Credit
Obligations and payments with respect to any Notes) shall be made without set-
off or counterclaim and shall be made to Agent in immediately available funds
(except for payments to be made to Issuing Bank as provided in Section 2.2 and
                                                               -----------    
except as Agent may otherwise consent) prior to 12:30 p.m., Chicago time, on the
date due at BAI's office at 231 South LaSalle Street, Chicago, Illinois 60697,
or at such other place as may be designated by Agent to Borrower in writing.
Any payments received after such time shall be deemed received on the next
Banking Day.  Whenever any payment to be made hereunder or under any Note shall
be stated to be due on a date other than a Banking Day, such payment may be made
on the next succeeding Banking Day, and such extension of time shall be included
in the calculation of interest and any fees.

          (b) (i) Borrower authorizes Agent, and Agent will, subject to the
provisions of this paragraph (b), apply the whole or any part of any amounts
                   -------------                                            
received by Agent (whether 

                                     -31-
<PAGE>
 
deposited in the Assignee Deposit Account or otherwise received by Agent) from
the collection of items of payment and proceeds of any Collateral (including
without limitation proceeds of insurance), against the principal and/or interest
of any Loans made hereunder and/or any other Liabilities, whether or not then
due, in such order of application as Agent may determine; provided, however,
                                                          --------  -------
that prior to the occurrence of an Event of Default, any such amounts received
by Agent shall, at Borrower's option, (y) be transferred to Borrower's Demand
Deposit Account or other operating account in accordance with written
instructions provided by Borrower, or (z) be applied in the manner, if any,
specifically set forth in this Agreement with respect to such payment and if no
such manner is specifically set out, then as follows: first, to payment of
                                                      -----
amounts then due with respect to fees (including Attorneys' Fees), charges and
expenses for which Borrower is liable pursuant to this Agreement and the Related
Agreements; second, to payment of amounts then due with respect to interest on
            ------
the Loans; third, to payment of the principal of the Loans.
           -----
          (ii) Notwithstanding anything to the contrary herein, (i) all cash,
checks, instruments and other items of payment, solely for purposes of
determining the occurrence of an Event of Default, shall be deemed received upon
actual receipt by Agent, unless the same is subsequently dishonored for any
reason whatsoever, (ii) for purposes of determining whether, under Sections 2.1
                                                                   ------------
and 2.2, there is availability for Loans or Letters of Credit, all cash, checks,
    ---                                                                         
instruments and other items of payment shall be applied against the Liabilities
when received by Agent and (iii) solely for purposes of interest calculation
hereunder, all cash, checks, instruments and other items of payment shall be
deemed to have been applied against the Liabilities on the first Banking Day
after receipt by Agent of collected funds with respect thereto; further
provided, that any amounts earned on such funds during the period after receipt
thereof by Agent and prior to application thereof against the Liabilities as
provided herein, shall be retained by Agent for Agent's own account.
Notwithstanding the foregoing, no checks, drafts or other instruments received
by Agent shall constitute final payment with respect to any Liabilities unless
and until such item of payment has actually been collected.

          (c) Borrower hereby authorizes Agent, and Agent may, in its sole and
absolute discretion, charge to Borrower at any time when due all or any portion
of any of the Liabilities consisting of principal or interest and, after three
Banking Days' prior notice, any other Liabilities including but not limited to
any Attorneys' Fees and other costs and expenses of Agent and Lenders for which
Borrower is liable pursuant to the terms of this Agreement or any
Related Agreement, or for which 

                                     -32-
<PAGE>
 
any other Obligor is liable pursuant to the terms of any Related Agreement, by
charging Borrower's Demand Deposit Account or any bank account of Borrower with
Agent or by advancing the amount thereof to Borrower as a Revolving Loan;
provided, however that the provisions of this Section 2.10(c) shall not affect
--------  -------                             ---------------
Borrower's obligation to pay when due all amounts payable by Borrower under this
Agreement, any Note or any Related Agreement, whether or not there are
sufficient funds therefor in the Demand Deposit Account or any such other bank
account of Borrower.

          2.11  Agent's Election Not to Enforce.  Notwithstanding any term or
                -------------------------------                              
condition of this Agreement to the contrary, Agent, in the sole and absolute
discretion of Requisite Lenders, at any time and from time to time, may suspend
or refrain from enforcing any or all of the restrictions imposed in this Section
                                                                         -------
2, but no such suspension or failure to enforce shall impair any right or power
-                                                                              
of Agent or any Lender under this Agreement, including without limitation any
right of each Lender to refrain from making a Loan or Issuing Bank to refrain
from issuing a Letter of Credit if all conditions precedent to such Lender's
obligation to make such Loan or Issuing Bank's obligation to issue such Letter
of Credit have not been satisfied.

          2.12  Reaffirmation.  Each Loan or Letter of Credit, or designation or
                -------------                                                   
continuation of a LIBOR Rate Loan, in each case requested by Borrower pursuant
to this Agreement, shall constitute an automatic certification by Borrower to
Agent and Lenders that (a) all of the representations and warranties of Borrower
in this Agreement and each of the Related Agreements are true and correct on the
date of such request to the same extent as if made on such date, except for such
changes as are specifically permitted hereunder (or under such Related
Agreement) and except for those representations and warranties made solely as of
the date hereof or the Closing Date and (b) immediately before and after making
the requested Loan or issuing the requested Letter of Credit, no Event of
Default or Unmatured Event of Default, then exists or would result therefrom.

          2.13  Setoff.  In addition to and not in limitation of all other
                ------                                                    
rights and remedies (including other rights of offset or banker's lien) that
Agent and Lenders may have under applicable law, each of Agent and each Lender
shall, upon the occurrence of any Event of Default described in Section 6.1, or
                                                                -----------    
any Unmatured Event of Default described in Section 6.1(e), have the right to
                                            --------------                   
appropriate and apply to the payment of the Liabilities (whether or not then
due), in such order of application as Agent may elect, any and all balances,
credits, deposits (general or special, time or demand, provisional or final),
accounts or moneys of Borrower then or thereafter with 

                                     -33-
<PAGE>
 
Agent or any Lender. Agent and each Lender shall promptly advise Borrower of any
such setoff and application but failure to do so shall not affect the validity
of such setoff and application.

          2.14  Closing Fee.  Borrower agrees to pay to BAI, for its own
                -----------                                             
account, in connection with the closing of this Agreement, a closing fee of
$300,000, which amount shall be deemed fully earned and shall be payable in full
on the Closing Date.  With Agent's consent, the amount of the closing fee may be
advanced to Borrower as a Revolving Loan.

          2.15  Settlements, Distributions and Apportionment of Payments.  On a
                --------------------------------------------------------       
weekly basis (or more frequently if required by Agent) (a "Settlement Date"),
Agent shall provide each Lender with a statement of the outstanding balance of
the Liabilities as of the end of the Banking Day preceding the Settlement Date
(the "Pre-Settlement Determination Date") and the current balance of the
Revolving Loans funded by each Lender (whether made directly by such Lender to
Borrower or constituting a settlement by such Lender of a previous
Disproportionate Advance made by Agent on behalf of such Lender to Borrower).
If such statement discloses that such Lender's current balance of the Revolving
Loans as of the Pre-Settlement Determination Date exceeds such Lender's Pro Rata
Share of the Revolving Loans outstanding as of the Pre-Settlement Determination
Date, then Agent shall, one (1) Banking Day after the Settlement Date, transfer
to such Lender, by wire transfer, the net amount due to such Lender in
accordance with such Lender's instructions, and if such statement discloses that
such Lender's current balance of the Revolving Loans as of the Pre-Settlement
Determination Date is less than such Lender's Pro Rata Share of the Revolving
Loans outstanding as of the Pre-Settlement Determination Date, then such Lender
shall, one (1) Banking Day after the Settlement Date, transfer to Agent, by wire
transfer the net amount due to Agent in accordance with Agent's instructions.
In addition, payments actually received by Agent with respect to the following
items shall be distributed by Agent to Lenders as follows:

             (a) Within one (1) Banking Day of receipt thereof by Agent,
     payments to be applied to interest on the Loans shall be paid to each
     Lender in proportion to its Pro Rata Share, subject to any adjustments for
     any Disproportionate Advances so that Agent shall receive interest on the
     Disproportionate Advances and each Lender shall only receive interest on
     the amount of funds actually advanced by such Lender; and

             (b) Within one (1) Banking Day of receipt thereof by Agent,
     payments to be applied to the unused line fee set forth in Section 2.4.2
                                                                -------------
     and the Letter of 

                                     -34-
<PAGE>
 
     Credit commission set forth in Section 2.2(b), shall each
                                    --------------
     be paid to each Lender in proportion to its Pro Rata Share.

Notwithstanding the foregoing, if a Lender has failed to remit its Pro Rata
Share of any Loans required to be made pursuant to Section 2.1.1 or has failed
                                                   -------------              
to make a settlement payment to Agent pursuant to this Section 2.15, no payment
                                                       ------------            
shall be made to such Lender by Agent at any time such Lender's share of the
outstanding Loans is less than such Lender's Pro Rata Share. If Agent or any
Lender fails to pay the other any payment due under this Agreement on its due
date, the party to whom such payment is due shall be entitled to recover
interest from the party obligated to make such payment at a rate per annum equal
to the overnight Federal Funds Rate.

3.   COLLATERAL.

          3.1  Grant of Security Interest.  As security for the payment of all
               --------------------------                                     
Loans now or hereafter made by, or on behalf of, Lenders to Borrower hereunder
or under any Note, and as security for the payment or other satisfaction of all
other Liabilities (including without limitation all reimbursement obligations
under any Letters of Credit), Borrower hereby grants to Agent, for the benefit
of itself and Lenders, a security interest in and to the following property of

             3.2  Accounts Receivable.
                  ------------------- 

          (a) If requested by Agent, Borrower shall notify Agent immediately of
all material disputes and claims by any Account Debtor and, if reasonably
requested by Agent after the occurrence and during the continuance of an Event
of Default, settle or adjust them, or cause them to be settled or adjusted, at
no expense to Agent or Lenders.  If Agent directs after the occurrence and
during the continuance of an Event of Default, no discount or credit allowance
shall be granted thereafter by Borrower or any Designated Subsidiary to any
Account Debtor, other than discounts and trade allowances offered in the
ordinary course of Borrower's or a Designated Subsidiary's business.  All
Account Debtor payments and all net amounts received by Agent in settlements,
adjustment or liquidation of any Account Receivable may be applied by Agent to
the Liabilities or credited to the Demand Deposit Account (subject to
collection) with Agent, as more fully described in Section 2.10.  If requested
                                                   ------------               
by Agent, Borrower will, and will cause each Designated Subsidiary to, make

                                     -36-
<PAGE>
 
proper entries in its books and records, disclosing the assignment of Accounts
Receivable to Agent, for the benefit of itself and Lenders.

          (b) Borrower warrants and covenants that:  (i) all of the Accounts
Receivable are and will continue to be bona fide existing obligations created by
the sale of goods, the rendering of services, or the furnishing of other good
and sufficient consideration to Account Debtors in the regular course of
business; (ii) all shipping or delivery receipts and other documents furnished
or to be furnished to Agent in connection therewith are and will be genuine; and
(iii) none of the Accounts Receivable identified or included on any schedule,
Borrowing Base Certificate or report as Eligible Accounts Receivable fail at the
time so identified or included to satisfy any of the requirements for
eligibility set forth in the definition of Eligible Accounts Receivable.

          (c) Agent is authorized and empowered (which authorization and power,
being coupled with an interest, is irrevocable until the last to occur of
termination of this Agreement and payment and performance in full of all of the
Payment Liabilities under this Agreement) at any time in its sole and absolute
discretion:

             (i) To request, in the name of Agent, in Borrower's or a Designated
     Subsidiary's name or the name of a third party, confirmation from any
     Account Debtor or party obligated under or with respect to any Collateral
     of the amount shown by the Accounts Receivable or other Collateral to be
     payable, or any other matter stated therein;

            (ii) To endorse in Borrower's or a Designated Subsidiary's name and
     to collect any chattel paper, checks, notes, drafts, instruments or other
     items of payment tendered to or received by Agent in payment of any Account
     Receivable or other obligation owing to Borrower or such Designated
     Subsidiary;

           (iii) After the occurrence and during the continuance of an Event of
     Default, to notify, either in Agent's name or Borrower's or a Designated
     Subsidiary's name, and/or to require Borrower or such Designated Subsidiary
     to notify, any Account Debtor or other Person obligated under or in respect
     of any Collateral, of the fact of Agent's Lien thereon, for the benefit of
     itself and Lenders, and of the collateral assignment 

                                     -37-
<PAGE>
 
     thereof to Agent, for the benefit of itself and Lenders;

            (iv) After the occurrence and during the continuance of an Event of
     Default, to direct, either in Borrower's or a Designated Subsidiary's name
     or Agent's name, and/or to require Borrower or such Designated Subsidiary
     to direct, any Account Debtor or other Person obligated under or in respect
     of any Collateral to make payment directly to Agent of any amounts due or
     to become due thereunder or with respect thereto; and

             (v) After the occurrence and during the continuance of an Event of
     Default, to demand, collect, surrender, release or exchange all or any part
     of any Collateral or any amounts due thereunder or with respect thereto, or
     compromise or extend or renew for any period (whether or not longer than
     the initial period) any and all sums which are now or may hereafter become
     due or owing upon or with respect to any of the Collateral, or enforce, by
     suit or otherwise, payment or performance of any of the Collateral either
     in Agent's own name or in the name of Borrower or a Designated Subsidiary.

Under no circumstances shall Agent be under any duty to act in regard to any of
the foregoing matters.  The costs relating to any of the foregoing matters,
including Attorneys' Fees and out-of-pocket expenses, and the cost of any
Depository Account, Assignee Deposit Account, or other bank account or accounts
which may be required hereunder, shall be borne solely by Borrower whether the
same are incurred by Agent or Borrower, and Agent may after three Banking Days'
prior to notice to Borrower advance same to Borrower as a Revolving Loan.

          (d) Borrower will notify its Account Debtors to make all payments in
respect of Borrower's Accounts Receivable directly to one or more lockbox
accounts evidenced by agreements in form and substance satisfactory to Agent.
All deposits to such lockbox accounts, and all of the checks, drafts, cash and
other remittances received by Borrower in payment or as proceeds of, or on
account of, any of the Accounts Receivable or other Collateral, shall be
deposited in special bank accounts (the "Depository Accounts") at such banks or
financial institutions as Agent shall consent.  Said proceeds shall be deposited
in precisely the form received except for Borrower's endorsement where necessary
to permit collection of items, which endorsement Borrower agrees to make.
Pending such deposit, Borrower agrees not to commingle any such checks, drafts,
cash and other 

                                     -38-
<PAGE>
 
remittances received by it with any of its funds or property, but will hold them
separate and apart therefrom and upon an express trust for Agent, for the
benefit of itself and Lenders, until deposit thereof is made in the Depository
Accounts. All funds in the Depository Accounts at the end of each Banking Day
will be wire transferred or transferred by other means acceptable to Agent to a
special bank account (the "Assignee Deposit Account") at BAI, over which Agent
alone has power of withdrawal. Borrower acknowledges that the maintenance of the
Assignee Deposit Account is solely for the convenience of Agent in facilitating
its own operations, and Borrower does not and shall not have any right, title or
interest in the Assignee Deposit Account or in the amounts at any time appearing
to the credit thereof, except to the extent that such amounts are transferred to
Borrower's Demand Deposit Account or operating account in accordance with
Section 2.10(b)(i). Borrower agrees not to maintain any depository accounts 
------------------                                 
other than Depository Accounts, the Demand Deposit Account and the Assignee
Deposit Account established pursuant to this Section 3.2(d). Upon the full and 
                                             --------------
final liquidation of all Payment Liabilities, Agent will pay over to Borrower
any excess amounts received by Agent as payment or proceeds of Collateral,
whether received by Agent as a deposit in the Assignee Deposit Account,
contained in a lockbox account or any Depository Account or received by Agent as
a direct payment on any of the sums due hereunder. Borrower will cause each of
its Designated Subsidiaries to establish accounts comparable to those set forth
above for the collection of the proceeds of their Accounts Receivable, and
Borrower shall cause each Designated Subsidiary to take all other actions to
implement the collection mechanism set forth in this Section 3.2(d).
                                                     -------------- 

          (e) Borrower appoints Agent, or any Person whom Agent may from time to
time designate, as Borrower's attorney and agent-in-fact with power:  (i) after
the occurrence and during the continuance of an Event of Default to notify the
post office authorities to change the address for delivery of Borrower's mail
to an address designated by Agent; (ii) to receive, open and dispose of all mail
addressed to Borrower, but received by Agent; (iii) to send requests for
verification of Accounts Receivable or other Collateral to Account Debtors; (iv)
to open an Assignee Deposit Account, Depository Accounts, lockbox accounts or
other accounts under Agent's sole control for the collection of Accounts
Receivable or other Collateral, if not required contemporaneously with the
execution hereof; and (v) to do all other things which Agent is permitted to do
under this Agreement or any Related Agreement or which are necessary to carry
out this Agreement and the Related Agreements.  Neither Agent nor any of its
directors, officers, employees or agents will be liable for any acts of
commission or omission nor for any error in judgment or mistake of fact or law,
unless the same shall have resulted 

                                     -39-
<PAGE>
 
from gross negligence or willful misconduct. The foregoing appointment and
power, being coupled with an interest, is irrevocable until all Payment
Liabilities under this Agreement are paid and performed in full and this
Agreement is terminated. Borrower expressly waives presentment, demand, notice
of dishonor and protest of all instruments and any other notice to which it
might otherwise be entitled.

          (f) If any Account Receivable or Contract Right, in either case in
excess of $2,000,000, and designated by Borrower as an Eligible Account, arises
out of a contract with the United States or any state or local governmental
entity, or any department, agency, or instrumentality of any thereof, Borrower
will, and will cause each Designated Subsidiary to, immediately notify Agent in
writing and execute any instruments and take any steps reasonably required by
Agent in order that all monies due and to become due under such contract shall
be assigned to Agent, for the benefit of itself and Lenders, and notice thereof
given to the applicable government under the Federal Assignment of Claims Act of
1940, as amended, or other applicable laws or regulations; provided, that with
respect to such Accounts Receivable and Contract Rights in existence on the
Closing Date or within 90 days thereafter, such steps need not be completed
until 90 days after the Closing Date.  The failure of Borrower or a Designated
Subsidiary to comply with this clause (f) shall not by itself constitute an
                               ----------                                  
Event of Default; rather, such failure will cause the applicable Account
Receivable or Contract Right to be deemed not to be an Eligible Account under
this Agreement.

          (g) If any Account Receivable or Contract Right is evidenced by
chattel paper or promissory notes, trade acceptances, or other instruments for
the payment of money, Borrower will, unless Agent shall otherwise agree, deliver
the originals of same to Agent, appropriately endorsed to Agent's order and,
regardless of the form of such endorsement, Borrower hereby expressly waives
presentment, demand, notice of dishonor, protest and notice of protest and all
other notices with respect thereto.

          3.3  Inventory.
               --------- 

          (a) Borrower warrants and covenants that:  (i) all of the Inventory
is, and at all times shall be, owned by Borrower or a Designated Subsidiary free
of all claims and Liens (except as set forth in Section 5.15); and (ii) neither
                                                ------------                   
Borrower nor any Designated Subsidiary will make any further assignment of any
thereof or create or permit to exist any further Lien thereon, unless approved
in writing by Requisite Lenders, nor 

                                     -40-
<PAGE>
 
permit any of Agent's rights therein to be affected by any attachment, levy,
garnishment or other judicial process.

          (b) Neither Agent nor any Lender shall be liable or responsible in any
way for the safekeeping of any Inventory delivered to it, to any bailee
appointed by or for it, to any warehouseman, or under any other circumstances,
other than for losses caused by its gross negligence or willful misconduct.
Neither Agent nor any Lender shall be responsible for collection of any proceeds
or for losses in collected proceeds held by Borrower or any Designated
Subsidiary in trust for Agent.  Any and all risk of loss for any or all of the
foregoing shall be upon Borrower and the Designated Subsidiaries.

          (c) Any material change in the value, or condition of any Inventory,
and any errors discovered in any monthly inventory certificate under Section
                                                                     -------
5.1.3 or any other inventory schedule delivered to Agent and Lenders, shall be
-----                                                                         
reported to Agent promptly.  Borrower represents and warrants that, as to each
schedule of Inventory delivered to Agent or any Lender:

             (i) The descriptions, origins, sizes, qualities, quantities,
     weights, and markings of all goods stated thereon, or on any attachment
     thereto, are true and correct in all respects;

            (ii) None of the goods are defective, of second quality, used, or
     goods returned after shipment, except where described as such; and

           (iii) All Inventory not included on such schedule has been
     previously scheduled.

          3.4  Supplemental Documentation.  At Agent's request, Borrower shall
               --------------------------                                     
execute and deliver, or cause to be executed and delivered, to Agent, at any
time or times hereafter, such agreements, documents, financing statements,
warehouse receipts, bills of lading, notices of assignment of Accounts
Receivable, schedules of Accounts Receivable assigned, and other written matter
necessary or reasonably requested by Agent to perfect and maintain perfected
Agent's Lien on the Collateral, for the benefit of itself and Lenders (all the
above hereinafter referred to as "Supplemental Documentation"), in form and
substance acceptable to Agent, and pay all taxes, fees and other costs and
expenses associated with any recording or filing of the Supplemental
Documentation. Borrower hereby irrevocably makes, constitutes and appoints Agent
(and all Persons designated by Agent for that purpose) as Borrower's true and
lawful attorney (and agent-in-fact) (which appointment and power, being coupled

                                     -41-
<PAGE>
 
with an interest, is irrevocable until the last to occur of termination of this
Agreement and payment and performance in full of all of the Payment Liabilities
under this Agreement) to sign the name of Borrower on any of the Supplemental
Documentation and to deliver any of the Supplemental Documentation to such
Persons as Agent in its sole and absolute discretion, may elect. Borrower agrees
that a carbon, photographic, photostatic, or other reproduction of this
Agreement or of a financing statement is sufficient as a financing statement.

          3.5  Collateral for the Benefit of Agent and Lenders.  All Liens
               -----------------------------------------------            
granted to Agent hereunder and under the Related Agreements and all Collateral
delivered to Agent hereunder and under the Related Agreements shall be deemed to
have been granted and delivered to Agent, for the benefit of itself and Lenders,
to secure the Liabilities.

          3.6  Certain Intellectual Property.  Borrower hereby grants Agent, for
               -----------------------------                                    
the benefit of Lenders, a world-wide irrevocable license or other right to use,
without charge, Borrower's labels, rights of use of any name, tradenames,
trademarks and advertising matter, or any assets and property of a similar
nature (collectively, the "Intangible Rights"), as they pertain to the
Collateral, in advertising for sale and selling any Collateral and Borrower's
rights under all applicable licenses and license agreements related to the
foregoing shall inure to Agent's benefit.  Such license shall remain in full
force and effect until all of the Liabilities have been repaid in full.  Any
transfer of or Lien on the Intangible Rights granted by Borrower to any other
Person shall be subject in all respects to Agent's rights granted hereunder.

Subsidiary party thereto, as applicable, enforceable against Borrower and each
such Designated Subsidiary in accordance with their respective terms.

          4.5  No Default.  Neither Borrower nor New Pioneer nor any Designated

statements as of (a) December 31, 1994 and Borrower's consolidated and
consolidating unaudited financial statements as of February 28, 1995, copies of
which have been furnished to Agent, have been prepared in conformity with GAAP
applied on a basis consistent with that of the preceding Fiscal Year and period

application of proceeds in respect thereof, and have been prepared in conformity

each Designated Subsidiary to maintain, complete and accurate books and records
(including but not limited to records relating to Accounts Receivable,
Inventory, and other Collateral and property), in which full and correct entries
in conformity with GAAP shall be made of all dealings and transactions in
relation to its respective business and activities.  Cause the books and records

calendar month to be posted and closed not more than thirty (30) days after the
last business day of such month except (i) forty-five (45) days after the end of

employees to accompany Agent on each such visit; and provided further, that
after the occurrence of an Event of Default, Agent and Lenders may have access
to such premises at such times as they desire, without having given prior
notice. Any and all such inspections, appraisals and/or audits by Agent and its
agents and employees relating to New Pioneer's, Borrower's or any Designated
Subsidiary's books and records and locations shall be at Borrower's expense, no
matter when the same shall occur; provided, that prior to the occurrence of an

maintain, insurance to such extent and against such hazards and liabilities as
is commonly maintained by companies similarly situated.  Keep the Collateral
properly housed and insured for its full insurable value (subject to customary
deductibles) against loss or damage by fire, theft, explosion, sprinklers and
such other risks as are customarily insured against by persons engaged in
business similar to that of Borrower or such Designated Subsidiary, as
applicable, with such companies, in such amounts and under policies in such form
as shall be reasonably satisfactory to Agent.  Certificates of such policies of
insurance in form and substance satisfactory to Agent have been delivered to
Agent prior to the date hereof together with evidence of payment of all premiums
therefor then due.  Borrower hereby directs all insurers under Borrower's
policies of insurance to pay all proceeds payable thereunder after the
occurrence and during the continuance of an Event of Default in respect of the
Collateral directly to Agent, as its interest may appear.  Borrower appoints
Agent and any Person whom Agent may from time to time designate (and all
officers, employees or agents designated by Agent or such Person) after the
occurrence and during the continuance of an Event of Default as Borrower's true
and lawful attorney and agent in fact with power to make, settle and adjust
claims under such policies of insurance, endorse the name of Borrower on any
check, draft, instrument or other item of payment for the proceeds of such
policies of insurance which are payable to Agent or any Lender hereunder and
make all determinations and decisions with respect to such policies of
insurance.  The foregoing appointment and power, being coupled with an interest,
is irrevocable until all Payment Liabilities under this Agreement are paid and
performed in full and this Agreement is terminated.  In the event Borrower or
any 

                                     -59-
<PAGE>
 
Designated Subsidiary at any time or times hereafter shall fail to obtain or
maintain any of the policies of insurance required herein or to pay any premium
in whole or in part relating thereto when due, then Agent, without waiving or
releasing any obligation of or default by Borrower hereunder, may at any time or
times thereafter (but shall be under no obligation to do so) obtain and maintain
such policies of insurance and pay such premiums and take any other action with
respect thereto which Agent deems advisable.  All sums so disbursed by Agent,
including reasonable Attorneys' Fees, court costs, expenses and other charges

the Federal Reserve Board on January 19, 1989 and regulations of the Comptroller
of the Currency, Department of the Treasury, 12 CFR Part 3, Appendix A, issued

capital required or expected to be maintained by Agent or such Lender or any
Person controlling Agent or such Lender in excess of any such increases
affecting Agent or such Lender as of the date hereof, and such increase is based
upon the existence of Agent's or such Lender's obligations hereunder and other
commitments of this type, then from time to time, within ten (10) days after
demand from Agent or such Lender, Borrower shall pay to Agent or such Lender, as
applicable, such amount or amounts as will compensate Agent or such Lender or
such controlling Person, as the case may be, for such increased capital
requirement.  The determination of any amount to be paid by Borrower under this

methods.  A certificate of Agent or such Lender, as applicable, setting forth

take such action on 


                                     -79-
<PAGE>
 
such Lender's behalf under the provisions of this Agreement and the Related
Agreements and to exercise such powers and perform such duties under this
Agreement and the Related Agreements as are specifically delegated to Agent by
the terms hereof and thereof, together with such other powers as are reasonably
incidental hereto and thereto. Agent may perform any of its duties hereunder or
under the Related Agreements by or through its agents or employees. The
provisions of this Section 10 are solely for the benefit of Agent and Lenders,
                   ----------
and neither Borrower nor any Obligor shall have any rights as a third party
beneficiary of any of the provisions hereof other than Section 10.9. In
                                                       ------------
performing its functions and duties under this Agreement and the Related
Agreements, Agent shall act solely as agent of Lenders and does not assume and
shall not be deemed to have assumed any obligation toward or relationship of
agency or trust with or for Borrower or any Obligor.

          10.2  Nature of Duties of Agent.  Agent shall have no duties,
                -------------------------                              
obligations or responsibilities except those expressly set forth in this
Agreement and the Related Agreements.  Neither Agent nor any of its officers,
directors, employees or agents shall be liable for any action taken or omitted
by it as such hereunder or under the Related Agreements or in connection
herewith or therewith, unless caused by its or their gross negligence or willful
misconduct.  The duties of Agent shall be mechanical and administrative in
nature; Agent shall not have by reason of this Agreement or the Related
Agreements a fiduciary relationship in respect of any Lender; and nothing in
this Agreement or the Related Agreements, expressed or implied, is intended to
or shall be so construed as to impose upon Agent any obligations in respect of
this Agreement or the Related Agreements except as expressly set forth herein or
therein.  No duty to act, or refrain from acting, and no other obligation
whatsoever, shall be implied on the basis of or imputed in respect of any right,
power or authority granted to Agent or shall become effective in the event of
any temporary or partial exercise of such rights, power or authority.

          10.3  Agent in its Capacity as Lender.  With respect to its obligation
                -------------------------------                                 
to lend under this Agreement and the Related Agreements, the Loans made by it
and its participation in Letters of Credit, Agent shall have the same rights and
powers under this Agreement and the Related Agreements as any Lender and may
exercise the same as though it were not Agent, and the terms "Lender" or
"Lenders" shall, unless the context otherwise indicates, include Agent in its
capacity as a Lender hereunder.  Agent, any Lender and their respective
affiliates may accept deposits from, lend money to, and generally engage in any
kind of banking or trust business with Borrower, or Related Parties of Borrower,
as if it were not Agent or as if it or they were not a 


                                     -80-
<PAGE>
 
Lender hereunder and without any duty to account therefor to the other parties
to this Agreement; provided, that the obligations of Borrower under such
transactions shall not be deemed to be Liabilities or secured by any Collateral
without the prior written agreement of the Requisite Lenders; provided, further
that Lenders acknowledge and agree that the obligations of Borrower to BAI or
any other Lender as Issuing Bank and with respect to any lockbox or bank account
maintained by or for the benefit of Borrower, including the Demand Deposit
Account, the Depository Accounts, and the Assignee Deposit Account, shall be
deemed to be Liabilities secured by the Collateral.

          10.4  Independent Credit Analysis.  Each Lender agrees that it has,
                ---------------------------                                  
independently and without reliance upon Agent, any other Lender, or the
directors, officers, agents, attorneys or employees of Agent or of any other
Lender, and instead in reliance upon information supplied to it by or on behalf
of GEV, New Pioneer, Borrower and/or each Designated Subsidiary, made its own
independent credit analysis and decision to enter into this Agreement and the
Related Agreements to which it is a party, and that it shall independently and
without reliance upon Agent, any other Lender, or the directors, officers,
agents, attorneys or employees of Agent or of any other Lender, continue to make
its own independent credit analysis and decisions in acting or not acting under
this Agreement and the Related Agreements. Except as otherwise expressly
provided herein, Agent shall not have any duty or responsibility, either
initially or on a continuing basis, to provide any Lender with any credit or
other information concerning the affairs, financial condition, litigation,
liabilities, or business of GEV, New Pioneer, Borrower, any Designated
Subsidiary or any other Obligor which may at any time come into the possession
of Agent (or any of its affiliates). In the event such information is furnished
to any Lender by Agent, Agent shall have no duty to confirm or verify its
accuracy or completeness and shall have no liability whatsoever with respect
thereto.

          10.5  General Immunity.  Neither Agent nor any of its directors,
                ----------------                                          
officers, agents, attorneys or employees shall be liable to any Lender for any
action taken or omitted to be taken by it or them under this Agreement or the
Related Agreements or in connection herewith or therewith except for its or
their own willful misconduct or gross negligence.  Without limiting the
generality of the foregoing, Agent:  (i) shall not be responsible to Lenders for
any recitals, statements, warranties or representations under this Agreement or
the Related Agreements or any agreement or document relative hereto or thereto
or for the financial or other condition of any Obligor, (ii) shall not be
responsible for the authenticity, accuracy, completeness, value, validity,
effectiveness, due execution, legality, genuineness, 

                                     -81-

Agreements or any other agreements or any assignments, certificates, requests,
financial statements, projections, notices, schedules or opinions of counsel
executed and delivered pursuant hereto or thereto, (iii) shall not be bound to
ascertain or inquire as to the performance or observance of any of the terms,
covenants or conditions of this Agreement or the Related Agreements on the part
of Obligors or of any of the terms of any such agreement by any party hereto or
thereto and shall have no duty to inspect the property (including the books and
records) of any Obligor, (iv) shall have no obligation whatsoever to Lenders or
to any other Person to assure that the Collateral exists or is owned by Borrower
or another Obligor or is cared for, protected or insured or that the Liens
granted to Agent herein or in Related Agreements or pursuant hereto or thereto
have been properly or sufficiently or lawfully created, perfected, protected,
enforced, realized upon or are entitled to any particular priority, and (v)
shall incur no liability under or in respect of this Agreement or the Related
Agreements or any other document by acting upon any notice, consent, certificate
or other instrument or writing (which may be by telegram, cable, telex,
telecopier or similar form of facsimile transmission) believed by Agent to be
genuine and signed or sent by the proper party.  Agent may consult with legal
counsel (including counsel for Borrower), independent public accountants and
other experts selected by Agent and shall not be liable for any action taken or
omitted to be taken in good faith in accordance with the advice of such counsel,
accountants or experts.

           10.6  Action by Agent.
                 --------------- 

          (a) Actual Knowledge.  Agent may assume that no Event of Default has
              ----------------                                                
occurred and is continuing, unless Agent has actual knowledge of the Event of
Default, has received notice from Borrower or Borrower's independent certified
public accountants stating the nature of the Event of Default, or has received
notice from a Lender stating the nature of the Event of Default and that such
Lender considers the Event of Default to have occurred and to be continuing.

          (b) Discretion to Act.  Agent shall have the right to request
              -----------------                                        
instructions from Requisite Lenders by notice to each Lender.  If Agent shall
request instructions from Requisite Lenders with respect to any act or action
(including the failure to act) in connection with this Agreement or any Related
Agreement, Agent shall be entitled to refrain from such act or taking such
action unless and until Agent shall have received instructions from Requisite
Lenders, and Agent shall not incur liability to any Person by reason of so
refraining.  Without limiting the foregoing, no Lender shall have any right of
action 


                                     -82-
<PAGE>
 
whatsoever against Agent as a result of Agent acting or refraining from
acting hereunder or under any Related Agreement in accordance with the
instructions of Requisite Lenders.  Agent may give any notice required under
Section 6 hereof without the consent of any of Lenders unless otherwise directed
---------                                                                       
by Requisite Lenders in writing and will, at the direction of Requisite Lenders,
give any such notice required under Section 6.  Except for any obligation
                                    ---------                            
expressly set forth in this Agreement or the Related Agreements, Agent may, but
shall not be required to, exercise its discretion to act or not act, except that
Agent shall be required to act or not act upon the instructions of Requisite
Lenders (unless all of Lenders are required to provide such instructions as
provided in Section 12.6) and those instructions shall be binding upon Agent and
            ------------                                                        
all Lenders; provided that Agent shall not be required to act or not act if to
             --------                                                         
do so would expose Agent to liability or would be contrary to this Agreement or
any Related Agreements or to applicable law.

          10.7  Right to Indemnity.  Agent shall be fully justified in failing
                ------------------                                            
or refusing to take any action under this Agreement or the Related Agreements or
in relation hereto or thereto unless it shall first be indemnified (upon
requesting such indemnification) to its satisfaction by Lenders against any and
all liability and expense which it may incur by reason of taking or continuing
to take any such action. Lenders further agree to indemnify Agent ratably in
accordance with their Pro Rata Shares for any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind and nature whatsoever which may be imposed on,
incurred by or asserted against Agent in any way relating to or arising out of
this Agreement or the other Related Agreements or the transactions contemplated
hereby or thereby, or the enforcement of any of the terms hereof or thereof or
of any other documents; provided no such liability, obligation, loss, damage,
penalty, action, judgment, suit, cost, expense or disbursement results from
Agent's gross negligence or willful misconduct. Each Lender agrees to reimburse
Agent in the amount of its Pro Rata Share of any out-of-pocket expenses for
which Agent is entitled to receive, but has not received, reimbursement pursuant

disposed of

in compliance with the terms of this Agreement (and, absent any actual knowledge
of Agent to the contrary, Agent may rely conclusively on any such certificate,
without further inquiry); (iii) constituting property in which Borrower or any
other Obligor owned no interest at the time the Lien was granted and at all
times thereafter; or (iv) if approved, authorized or ratified in writing by
Agent at the direction of all Lenders.  Upon request by Agent at any time, each
Lender will confirm in writing Agent's authority to release particular types or
items of Collateral pursuant to this Section 10.11.

(whether voluntary, involuntary, through exercise of any right of set off, or
otherwise) on account of the Liabilities in excess of the amount to which it is
entitled pursuant to this Agreement, such Lender shall forthwith purchase from
the other Lenders such participations in such other Lenders' claims against
Borrower as shall be necessary to cause such purchasing Lender to share the
excess payment with the other Lenders in accordance with the provisions of this
Agreement; provided, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from such other
Lender shall be rescinded and such other Lenders shall repay to the purchasing
Lender the purchase price to the extent of their portion of such recovery
together with an amount equal to the share (according to the proportion of (i)
the amount of such other Lenders' required repayment, to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid or
payable by purchasing Lender in respect of the total amount recovered.

          10.14  Lenders to Act as Agents.  If any Collateral or proceeds
                 ------------------------                                
thereof at any time comes into the possession or under the control of any
Lender, such Lender shall hold such Collateral or proceeds thereof as agent for
the joint benefit of Lenders, and will, upon receipt therefor, deliver such
Collateral or proceeds thereof to Agent.

                ----------------------                                       
Section 12.3, Borrower agrees to pay BAI on demand by BAI the customary fees and
------------                                                                    
charges of BAI for maintenance of accounts with BAI or for providing other
services 


                                     -88-
<PAGE>
 
to Borrower and if not so paid, each Lender shall, without regard to
any other provision of this Agreement or any other Related Agreement or any
defense that Borrower may have to its obligation to pay BAI in connection with
such fees and charges, pay BAI for such Lender's Pro Rata Share of such fees and

Revolving Loans. Each Lender (other than BAI) acknowledges and agrees that it

the highest applicable rate, such Lender shall promptly refund its Pro Rata
Share of such excess interest to Borrower.

          12.6  No Waiver by Agent or any Lender; Amendments.  No failure or
                --------------------------------------------                
delay on the part of Agent or any Lender in the exercise of any power or right,
and no course of dealing between Borrower and Agent or any Lender shall operate
as a waiver of such power or right, nor shall any single or partial exercise of
any power or right preclude other or further exercise thereof or the exercise of
any other power or right.  The remedies provided for herein are cumulative and
not exclusive of any remedies which may be available to Agent or any Lender at
law or in equity.  No notice to or demand on Borrower not required hereunder
shall in any event entitle Borrower to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the right of Agent or
any Lender to any other or further action in any circumstances without notice or
demand.  No amendment, modification or waiver of, or consent with respect to,
any provision of this Agreement or any Related Agreement shall in any event be
effective unless the same shall be in writing and signed and delivered by
Requisite Lenders.  Notwithstanding the foregoing, any amendment, modification,
termination, waiver or consent with respect to any of the following provisions
of this Agreement shall be effective only by a written agreement, signed by each
Lender affected thereby:  (a) increase in the amount of the Maximum Loan Amount

                                     -89-

charges) (including, without limitation, any Letter of Credit fees or charges)
or other amounts payable to such Lender, (d) change in the aggregate Pro Rata
Share of Lenders which shall be required for Lenders or any of them to take
action hereunder or amend the definition of "Requisite Lenders," or (e)
                                             -----------------         
amendment of this Section 12.6.  Agent may, but shall have no obligation to,
                  ------------                                              
with the written concurrence of any Lender, execute amendments, modifications,
waivers or consents on behalf of that Lender.  Any waiver of any provision of
this Agreement, and any consent to any departure by Borrower from the terms of
any provision of this Agreement, shall be effective only in the specific
instance and for the specific purpose for which given.

          12.7  Termination of Revolving Credit.  Borrower may terminate the
                -------------------------------

outstanding principal balance of the Loans and all other Payment Liabilities

All of Agent's and each Lender's rights and remedies, the Liens of Agent on the
Collateral, for the benefit of itself and Lenders, and all of Borrower's duties
and obligations under this Agreement shall survive termination of the Credit
extended to Borrower hereunder until all of the Payment Liabilities hereunder
have been finally paid and performed in full.  The termination or cancellation
of the Credit shall not affect or impair the liabilities and obligations of
Borrower or any one or more of the Obligors to Agent and Lenders or Agent's and
each Lender's rights with respect to any Loans and advances made and other
Liabilities incurred prior to such termination or with respect to the
Collateral.

          12.8  Notices.  Except as otherwise expressly provided herein, any
                -------

remaining portion of such assigning Lender's rights and obligations under this
Agreement, the assigning Lender shall cease to be a party hereto).

Amount and principal amount of the Loans owing to each Lender from time to time.
The entries in the Register shall be conclusive and binding for all purposes,

computation of interest on LIBOR Rate Loans shall include the date on which the
applicable Interest Rate Period began, but shall exclude the last day of the
applicable Interest Rate Period.  LIBOR Rate Loans not repaid on the last day of
the Interest Rate Period applicable thereto shall be continued or converted into
Revolving Loans bearing interest at the Reference Rate, as applicable, and bear
interest as provided herein, from and including the last day of such Interest

Period, whether because of acceleration, prepayment or otherwise, Borrower will
indemnify each Lender and Agent for any loss or cost incurred by it resulting
therefrom, including without limitation any loss or cost in liquidating or
employing deposits acquired to fund or maintain such Loan.  Agent shall deliver
a written statement as to the amount due, if any, under this Section, after
consultation with each Lender so affected.  Such written statement shall set
forth in reasonable detail the calculations upon which Agent and each Lender
determined such amount and shall be final, conclusive and binding on Borrower in
the absence of manifest error.  Determination of amounts payable under this
Section shall be calculated as though each Lender funded its LIBOR Rate Loans
through the purchase of a deposit of the type and maturity corresponding to the
LIBOR Rate Loan and applicable Interest Rate Period bearing interest at the
LIBOR Base Rate less two and seventy-five hundredths percent (2.75%), as
applicable, whether or not the Lender actually funded the Loan in that manner.

               -------------------------------------                           
that maintenance of any of its LIBOR Rate Loans would violate any applicable
law, rule, regulation or directive, whether or not having the force of law, the
Lender shall immediately notify Agent thereof and Agent shall suspend the
availability of such LIBOR Rate Loans and require any LIBOR Rate Loans
outstanding and so affected to be repaid; or if any Lender determines that (i)
deposits of a type or maturity appropriate to match fund LIBOR Rate Loans are
not available, (ii) the LIBOR Rate does not accurately reflect the cost of
making such Loans, or (iii) the Lender's ability to make or maintain LIBOR Rate
Loans has been materially adversely affected by the occurrence of any event
after the date hereof, then Lender shall immediately notify Agent thereof and
Agent shall suspend the availability of the LIBOR Rate Loans, as applicable,
after the date of any such determination.

          3.6  Lenders' Obligation to Mitigate.  Agent and each Lender agrees
               -------------------------------                               
that if it becomes aware of either (i) the occurrence of an event or the
existence of a condition described in Section 9.3 of the Loan Agreement or
                                      -----------                         
Section 3.5 hereof that would cause Agent or such Lender to make a determination
-----------                                                                     
of the nature described therein, or (ii) the imposition, assessment or
collection of any taxes on or in respect of any Loan or Letter of Credit, Agent
or such Lender will, to the extent consistent with its internal policies, use
reasonable efforts to issue, make, fund or maintain the affected Letters of
Credit or Loans through another lending office of such Agent or Lender, if any,
if, as a result thereof, the additional amounts that would otherwise be required
to be paid to Agent or such Lender in respect thereof, would be reduced, or
LIBOR Rate Loans could be maintained, as the case may be, and if, as determined
by Agent or such Lender in its reasonable discretion, the issuing, making,
funding or maintaining of such Letters of Credit or Loans through such other
lending office would not adversely affect Agent or such Lender or such Letters
of Credit or Loans.  Borrower hereby agrees to pay all reasonable expenses
incurred by Agent or any Lender in using another lending office pursuant to this
Section 3.6.

("Interest Coverage Ratio") of (a) net earnings (excluding interest income)
before interest expense, tax expense, depreciation and amortization for any
period set forth below, to (b) interest expense (net of interest income not
otherwise included in the calculation of earnings) for such period, each
determined for New Pioneer, Borrower and its Subsidiaries on a consolidated
basis, and in accordance with GAAP, to be less than 1.0:1.0 at the end of each
month for the preceding twelve month period; provided, however that if the

                           MASTER CORPORATE GUARANTY
                           -------------------------


          Pioneer Americas, Inc., a Delaware corporation (the "Borrower") has
requested that Bank of America Illinois ("BAI") and the other Lenders now or
hereafter party to the Loan Agreement (as defined below) (the "Lenders"),
provide certain financial accommodations to the Borrower.  As one of the
conditions to providing financing to the Borrower, BAI, as agent for itself and
each of the other Lenders ("Agent"), has required that each of the subsidiaries
of Borrower set forth on Exhibit A attached hereto (collectively, "Guarantors",
and individually a "Guarantor") guaranty the obligations of the Borrower to
Agent and the Lenders.

          For value received and in consideration of any loan, advance, or
financial accommodation of any kind whatsoever heretofore, now or hereafter
made, given or granted to the Borrower by Agent and the Lenders, each Guarantor
jointly and severally unconditionally guaranties the full and prompt payment
when due, whether at maturity or earlier, by reason of acceleration or
otherwise, and at all times thereafter, of all "Liabilities" as such term is
defined in that certain Loan and Security Agreement among the Borrower, Agent
and the Lenders of even date herewith (the "Loan Agreement") (all such
Liabilities being hereinafter referred to as "Borrower's Obligations").  Each
Guarantor further agrees to pay all costs and expenses including, without
limitation, all court costs and attorneys' and paralegals' fees and expenses
paid or incurred by Agent or the Lenders in endeavoring to collect all or any
part of Borrower's Obligations from, or in prosecuting any action against, any
Guarantor or any other guarantor of all or any part of Borrower's Obligations.

          Each Guarantor hereby agrees that its obligations under this Master
Corporate Guaranty shall be unconditional, irrespective of (i) the validity or
enforceability of Borrower's Obligations or any part thereof, or of any
promissory note or other document evidencing all or any part of Borrower's
Obligations, (ii) the absence of any attempt to collect Borrower's Obligations
from the Borrower, any Guarantor or any other guarantor, or other action to
enforce the same, (iii) the waiver or consent by Agent or the Lenders with
respect to any provision of any instrument evidencing Borrower's Obligations, or
any part thereof, or any other agreement now or hereafter executed by the
Borrower and delivered to Agent and the Lenders, (iv) failure by Agent to take
any steps to perfect and maintain its security interest in, or to preserve its
rights to, any security or collateral for Borrower's Obligations, for its
benefit or the ratable benefit of the Lenders, (v) Agent's election, in any
proceeding instituted under Chapter 11 of Title 11 of the United States Code (11
U.S.C. Section 101 et seq.), as amended (the "Bankruptcy Code") of the
application of Section 1111(b)(2) of the Bankruptcy Code, (vi) any borrowing or
grant of a security interest by the Borrower as debtor-in-possession, under
Section 364 of the Bankruptcy Code, (vii) the disallowance, under
<PAGE>
 
Section 502 of the Bankruptcy Code, of all or any portion of Agent and the
Lenders' claim(s) for repayment of Borrower's Obligations, or (viii) any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of the Borrower or a guarantor.

          Until the Payment Liabilities have been repaid in full and there is no
further commitment to make Loans or issue Letters of Credit under the Loan
Agreement, no payment made by or for the account or benefit of any Guarantor
(including without limitation (i) a payment made by the Borrower in respect of
Borrower's Obligations, (ii) a payment made by any Guarantor in respect of
Borrower's Obligations, (iii) a payment made by any person under any other
guaranty of Borrower's Obligations or (iv) a payment made by means of set-off or
other application of funds by Agent or the Lenders) pursuant to this Master
Corporate Guaranty shall entitle any Guarantor, by subrogation or otherwise, to
any payment by the Borrower or from or out of any property of the Borrower, and
no Guarantor may exercise any right or remedy against the Borrower or any
property of the Borrower including, without limitation, any right of
contribution or reimbursement by reason of any performance by such Guarantor
under this Master Corporate Guaranty.  The provisions of this paragraph shall
survive the termination of this Master Corporate Guaranty or the release or
discharge of any and all Guarantors from liability hereunder.  Each Guarantor
and Agent hereby agree that the Borrower is and shall be a third party
beneficiary of the provisions of this paragraph.

          Each Guarantor hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of receivership or
bankruptcy of the Borrower, protest or notice with respect to Borrower's
Obligations and all demands whatsoever, and covenants that this Master Corporate
Guaranty will not be discharged, except by complete and irrevocable payment and
performance of the obligations and liabilities contained herein.  No notice to
any party, including any Guarantor, shall be required for Agent to make demand
hereunder.  Such demand shall constitute a mature and liquidated claim against
each Guarantor.  Upon any Event of Default (as defined in the Loan Agreement) by
the Borrower as provided in any instrument or document evidencing all or any
part of Borrower's Obligations, including without limitation the Loan Agreement,
Agent may, at its sole election, proceed directly and at once, without notice,
against any Guarantor, or all of the Guarantors, to collect and recover the full
amount or any portion of Borrower's Obligations, without first proceeding
against the Borrower, any other Guarantor, or any other person, firm, or
corporation, or against any security or collateral for Borrower's Obligations.
Agent shall have the exclusive right to determine the application of payments
and credits, if any, from any Guarantor, the Borrower or from any other person,
firm or corporation, on account of Borrower's Obligations or of any other
liability of any Guarantor to Agent and the Lenders.

                                      -2-
<PAGE>
 
          Agent and the Lenders are hereby authorized, without notice or demand
and without affecting the liability of any Guarantor hereunder, to, from time to
time, (i) renew, extend, accelerate or otherwise change the time for payment of,
or other terms relating to, Borrower's Obligations or otherwise modify, amend or
change the terms of any promissory note or other agreement, document or
instrument now or hereafter executed by the Borrower and delivered to Agent and
the Lenders; (ii) accept partial payments on Borrower's Obligations; (iii) take
and hold security or collateral for the payment of Borrower's Obligations
guaranteed hereby, or for the payment of this Master Corporate Guaranty, or for
the payment of any other guaranties or Borrower's Obligations or other
liabilities of the Borrower, and exchange, enforce, waive and release any such
security or collateral; (iv) apply such security or collateral and direct the
order or manner of sale thereof as in its sole discretion it may determine; and
(v) settle, release, compromise, collect or otherwise liquidate Borrower's
Obligations and any security or collateral therefor in any manner, without
affecting or impairing the obligations of any Guarantor hereunder.

          At any time after maturity of Borrower's Obligations, Agent may, in
its sole discretion, without notice to any Guarantor and regardless of the
acceptance of any security or collateral for the payment hereof, appropriate and
apply toward payments of Borrower's Obligations (i) any indebtedness due or to
become due from Agent or any of the Lenders to any Guarantor, and (ii) any
moneys, credits or other property belonging to any Guarantor, at any time held
by or coming into the possession of Agent or any of the Lenders or any
affiliates thereof, whether for deposit or otherwise.

          Each Guarantor hereby assumes responsibility for keeping itself
informed of the financial condition of the Borrower, the other Guarantors, and
any and all endorsers and/or other guarantors of any instrument or document
evidencing all or any part of Borrower's Obligations and of all other
circumstances bearing upon the risk of nonpayment of Borrower's Obligations or
any part thereof that diligent inquiry would reveal and each Guarantor hereby
agrees that Agent shall have no duty to advise any Guarantor of information
known to Agent or the Lenders regarding such condition or any such
circumstances.  Each Guarantor hereby acknowledges familiarity with the
Borrower's financial condition and has not relied on any statements by Agent or
the Lenders in obtaining such information.  In the event Agent, in its sole
discretion, undertakes at any time or from time to time to provide any such
information to any Guarantor, Agent shall be under no obligation (i) to
undertake any investigation not a part of its regular business routine, (ii) to
disclose any information which, pursuant to accepted or reasonable commercial
finance practices, Agent wishes to maintain confidential or (iii) to make any
other or future disclosures of such information or any other information to such
Guarantor.

          Notwithstanding any provision of this Master Corporate Guaranty to the
contrary, it is intended that this Master Corporate Guaranty, and any liens and
security interests granted by any Guarantor to secure this Master Corporate
Guaranty, not constitute a "Fraudulent Conveyance" (as defined below) by any
Guarantor.  Consequently, each Guarantor agrees that if this Master Corporate
Guaranty, or any liens or security interests securing this Master Corporate
Guaranty, would, but for the application of this sentence, constitute a
Fraudulent Conveyance by it, this Master Corporate Guaranty and each such lien
and security interest shall be valid and enforceable only to the maximum extent
that would not cause this Master Corporate Guaranty or such lien or security
interest to constitute a Fraudulent Conveyance by such Guarantor, and this
Master Corporate Guaranty shall automatically be deemed to have been amended
accordingly at all relevant times.  For purposes hereof, "Fraudulent Conveyance"
means a fraudulent conveyance under Section 548 of the Bankruptcy Code or a
fraudulent conveyance or fraudulent transfer under the provisions of any
applicable fraudulent conveyance or fraudulent transfer law or similar law of
any state, nation or other governmental unit, as in effect from time to time.

          Each Guarantor consents and agrees that Agent shall be under no
obligation to marshall any assets in favor of any Guarantor or against or in
payment of any or all of Borrower's Obligations.  Each Guarantor further agrees
that, to the extent that the Borrower makes a payment or payments to Agent, or
Agent receives any proceeds of collateral, for its benefit and the ratable
benefit of the Lenders, which payment or payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to the Borrower, its estate, trustee, receiver or
any other party, including without limitation any Guarantor, under any
bankruptcy law, state or federal law, common law or equitable cause, then to the
extent of such payment or repayment, Borrower's Obligations or the part thereof
which has been paid, reduced or satisfied by such amount shall be reinstated and
continued in full force and effect as of the date such initial payment,
reduction or satisfaction occurred and this Master Corporate Guaranty shall
continue to be in existence and in full force and effect, irrespective of
whether any evidence of indebtedness has been surrendered or cancelled.

          Each Guarantor also waives all setoffs and counterclaims and all
presentments, demands for performance, notices of nonperformance, protests,
notices of protest, notices of dishonor, and notices of acceptance of this
Master Corporate Guaranty.  Each Guarantor further waives all notices of the
existence, creation or incurring of new or additional indebtedness, arising
either from additional loans extended to the Borrower or otherwise, and also
waives all notices that the principal amount, or any portion thereof, and/or any
interest on any instrument or document evidencing all or any part of Borrower's
Obligations is due, notices of any and all proceedings to collect from the
maker, any

                                      -4-
<PAGE>
 
endorser or any other Guarantor or guarantor of all or any part of Borrower's
Obligations, or from anyone else, and, to the extent permitted by law, notices
of exchange, sale, surrender or other handling of any security or collateral
given to Agent, for its benefit and the ratable benefit of the Lenders, to
secure payment of Borrower's Obligations.

          No delay on the part of Agent in the exercise of any right or remedy
shall operate as a waiver thereof, and no single or partial exercise by Agent of
any right or remedy shall preclude any further exercise thereof; nor shall any
modification or waiver of any of the provisions of this Master Corporate
Guaranty be binding upon Agent or the Lenders, except as expressly set forth in
a writing duly signed and delivered on Agent's behalf by an authorized officer
or agent of Agent.  Agent's or the Lenders' failure at any time or times
hereafter to require strict performance by the Borrower or any Guarantor of any
of the provisions, warranties, terms and conditions contained in any promissory
note, security agreement, agreement, guaranty, instrument or document now or at
any time or times hereafter executed by the Borrower or any Guarantor and
delivered to Agent and the Lenders shall not waive, affect or diminish any right
of Agent and the Lenders at any time or times hereafter to demand strict
performance thereof and such right shall not be deemed to have been waived by
any act or knowledge of Agent or the Lenders, or their respective agents,
officers or employees, unless such waiver is contained in an instrument in
writing signed by an officer or agent of Agent, and directed to the Borrower or
a Guarantor, as applicable, specifying such waiver.  No waiver by Agent and the
Lenders of any default shall operate as a waiver of any other default or the
same default on a future occasion, and no action by Agent or the Lenders
permitted hereunder shall in any way affect or impair Agent's or the Lenders'
rights or the obligations of any Guarantor under this Master Corporate Guaranty.
Any determination by a court of competent jurisdiction of the amount of any
principal and/or interest owing by the Borrower to Agent and the Lenders shall
be conclusive and binding on each Guarantor irrespective of whether such
Guarantor was a party to the suit or action in which such determination was
made.

          This Master Corporate Guaranty shall terminate upon payment of all of
the Payment Liabilities (as defined in the Loan Agreement) and the termination
of the Loan Agreement in connection with its terms.

          This Master Corporate Guaranty shall be binding upon each Guarantor
and upon the successors and permitted assigns of such Guarantor and shall inure
to the benefit of Agent's and the Lenders' respective successors and assigns;
all references herein to the Borrower shall be deemed to include their
successors and permitted assigns and all references herein to Agent or the
Lenders shall be deemed to include their successors and assigns.  The Borrower's
successors and permitted assigns shall include, without

                                      -5-
<PAGE>
 
limitation, a receiver, trustee or debtor in possession of or for the Borrower.
All references to the singular shall be deemed to include the plural where the
context so requires.

          EACH GUARANTOR HEREBY CONSENTS TO THE JURISDICTION OF STATE OR FEDERAL
COURT LOCATED WITHIN COOK COUNTY, ILLINOIS AND WAIVES ANY OBJECTION WHICH IT MAY
HAVE BASED ON IMPROPER VENUE OR FORUM NON CONVENIENS TO THE CONDUCT OF ANY

SHALL HAVE BEEN POSTED TO SUCH GUARANTOR'S AGENT SET FORTH BELOW.  EACH
GUARANTOR HEREBY IRREVOCABLY APPOINTS CT CORPORATION SYSTEM AS ITS AGENT FOR THE
PURPOSE OF ACCEPTING THE SERVICE OF ANY PROCESS WITHIN THE STATE OF ILLINOIS.
THE BORROWER, EACH GUARANTOR AND AGENT EACH HEREBY WAIVE, TO THE EXTENT
PERMITTED BY LAW, TRIAL BY JURY.  BORROWER AND EACH GUARANTOR FURTHER WAIVES ANY
BOND OR SURETY OR SECURITY UPON SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER, BE
REQUIRED OF AGENT.  NOTHING CONTAINED HEREIN SHALL AFFECT THE RIGHT OF AGENT TO
SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR AFFECT THE RIGHT OF
AGENT TO BRING ANY ACTION OR PROCEEDING AGAINST ANY GUARANTOR OR ITS PROPERTY IN
THE COURTS OF ANY OTHER JURISDICTION.

          THIS MASTER CORPORATE GUARANTY SHALL BE GOVERNED IN ALL RESPECTS BY
THE LAWS OF THE STATE OF ILLINOIS.

          Wherever possible each provision of this Master Corporate Guaranty
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Master Corporate Guaranty shall be
prohibited by or invalid under such law, such provision shall be ineffective to
the extent of such prohibition or invalidity without invalidating the remainder
of such provision or the remaining provisions of this Master Corporate Guaranty.

          Each Guarantor hereby certifies that it has all necessary corporate
authority to grant and execute this Master Corporate Guaranty.

          The obligations of each Guarantor are secured by that certain Master
Collateral Security Agreement, of even date herewith, between Agent and each
Guarantor.

          2.  SECURITY INTEREST.
              ----------------- 

          2.1  Grant of Security Interest.  To secure the payment and
               --------------------------                            
performance of the Obligations, each Guarantor hereby grants to Agent, for the
benefit of itself and Lenders, a continuing security interest in the Collateral.

          2.2  Accounts Receivable.
               ------------------- 

          (a) If requested by Agent, each Guarantor shall notify Agent
immediately of all material disputes or claims by any Account Debtor and, if
reasonably requested by Agent after the occurrence and during the continuance of
a Default, settle or adjust them, or cause them to be settled or adjusted, at no
expense to Agent or Lenders.  If Agent directs after the occurrence and during
the continuance of a Default, no discount or credit allowance shall be granted
thereafter by any Guarantor to any Account Debtor, other than discounts and
trade allowances offered in the ordinary course of such Guarantor's business.
If requested by Agent, each Guarantor will make proper entries in its books and
records, disclosing the assignment of Accounts Receivable to Agent, for the
benefit of itself and Lenders.

          (b) Each Guarantor warrants and covenants that:  (i) all of such
Guarantor's Accounts Receivable are and will continue to be bona fide existing
obligations created by the sale of goods, the rendering of services, or the
furnishing of other good and sufficient consideration to such Guarantor's
Account Debtors in the regular course of business; (ii) all shipping or delivery
receipts and other documents furnished or to be furnished to Agent by such
Guarantor upon Agent's request in connection therewith are and will be genuine;
and (iii) none of such Guarantor's Accounts Receivable identified or included on
any schedule, Borrowing Base Certificate or report as Eligible Accounts
Receivable fail at the time so identified or included to satisfy any of the
requirements for eligibility set forth in the definition of Eligible Accounts
Receivable.

          (c) Agent is authorized and empowered (which authorization and power,
being coupled with an interest, is irrevocable until the last to occur of
termination of this Agreement and the Guaranty Documents, termination of the
Loan Agreement, and payment and performance in full of all of the Obligations)
at any time in its sole and absolute discretion:

                                      -3-
<PAGE>
 
             (i) To request, in the name of Agent, Borrower, any Guarantor or a
     third party, confirmation from any Account Debtor or party obligated under
     or with respect to any Collateral of the amount shown by the Accounts
     Receivable or other Collateral to be payable, or any other matter stated
     therein;

            (ii) To endorse in any Guarantor's name and to collect any chattel
     paper, checks, notes, drafts, instruments or other items of payment
     tendered to or received by Agent in payment of any Account Receivable or
     other obligation owing to such Guarantor;

           (iii) After the occurrence and during the continuance of a
     Default, to notify, either in Agent's name, Borrower's name or any
     Guarantor's name, and/or to require any Guarantor to notify, any Account
     Debtor or other Person obligated under or in respect of any Collateral, of
     the fact of Agent's Lien thereon, for the benefit of itself and Lenders,
     and of the collateral assignment thereof to Agent, for the benefit of
     itself and Lenders;

            (iv) After the occurrence and during the continuance of a Default,
     to direct, either in any Guarantor's name or Agent's name, and/or to
     require any Guarantor to direct, any Account Debtor or other Person
     obligated under or in respect of any Collateral to make payment directly to
     Agent of any amounts due or to become due thereunder or with respect
     thereto; and

             (v) After the occurrence and during the continuance of a Default,
     to demand, collect, surrender, release or exchange all or any part of any
     Collateral or any amounts due thereunder or with respect thereto, or
     compromise or extend or renew for any period (whether or not longer than
     the initial period) any and all sums which are now or may hereafter become
     due or owing upon or with respect to any of the Collateral, or enforce, by
     suit or otherwise, payment or performance of any of the Collateral either
     in Agent's own name or in the name of any Guarantor.

Under no circumstances shall Agent be under any duty to act in regard to any of
the foregoing matters.  The costs relating to any of the foregoing matters,
including Attorneys' Fees and out-of-pocket expenses, and the cost of any
Depository Account, Assignee Deposit Account, or other bank account or accounts
which may be required hereunder, shall be borne solely by Guarantors whether the
same are incurred by Agent or Guarantors.

          (d) Each Guarantor will notify its Account Debtors to make all
payments in respect of such Guarantor's Accounts

                                      -4-
<PAGE>
 
Receivable directly to one or more lockbox accounts evidenced by agreements in
form and substance satisfactory to Agent.  All deposits to such lockbox
accounts, and all checks, drafts, cash and other remittances in payment or as
proceeds of, or on account of, any of the Accounts Receivable or other
Collateral, shall be deposited in special bank accounts (the "Depository
Accounts") at such banks or financial institutions as Agent shall consent.  Said
proceeds shall be deposited in precisely the form received except for such
Guarantor's endorsement where necessary to permit collection of items, which
endorsement such Guarantor agrees to make.  Pending such deposit, each Guarantor
agrees not to commingle any such checks, drafts, cash and other remittances with
any of its funds or property, but will hold them separate and apart therefrom
and upon an express trust for Agent, for the benefit of itself and Lenders,
until deposit thereof is made in the Depository Accounts.  All funds in the
Depository Accounts at the end of each Banking Day will be wire transferred or
transferred by other means acceptable to Agent to a special bank account (the
"Assignee Deposit Account") at Bank of America Illinois over which Agent alone
has power of withdrawal.  Each Guarantor acknowledges that the maintenance of
the Assignee Deposit Account is solely for the convenience of Agent in
facilitating its own operations, and no Guarantor has or shall have any right,
title or interest in the Assignee Deposit Account or in the amounts at any time
appearing to the credit thereof, it being understood that if proceeds in the
Assignee Deposit Account are subsequently transferred to the Demand Deposit
Account or operating account, or a cash collateral account in accordance with
Section 2.10(b)(i) of the Loan Agreement, at the direction of Borrower, one or
more of the Guarantors may be entitled to such proceeds.  Each Guarantor agrees
not to maintain any depository accounts other than Depository Accounts, the
Demand Deposit Account and the Assignee Deposit Account established pursuant to
this Section 2.2(d).  Upon the full and final liquidation of all Payment
     --------------                                                     
Liabilities, Agent will pay over to Borrower, on behalf of such Guarantor any
excess amounts received by Agent as payment or proceeds of Collateral, whether
received by Agent as a deposit in the Assignee Deposit Account, contained in a
lockbox account or any Depository Account or received by Agent as a direct
payment on any of the sums due hereunder.

          (e) Each Guarantor appoints Agent, or any Person whom Agent may from
time to time designate, as such Guarantor's attorney and agent-in-fact with
power:  (i) after the occurrence and during the continuance of a Default, to
notify the post office authorities to change the address for delivery of such
Guarantor's mail to an address designated by Agent; (ii) to receive, open and
dispose of all mail addressed to such Guarantor, but received by Agent; (iii) to
send requests for verification of Accounts Receivable or other Collateral to
Account Debtors; (iv) to open, under Agent's sole control (subject, where
applicable, to the provisions of the Loan Agreement), an Assignee Deposit
Account, Depository Accounts, Lockbox accounts or other accounts required under
this Agreement for the collection of Accounts Receivable or other Collateral, if

                                      -5-
<PAGE>
 
not required contemporaneously with the execution hereof and if not previously
opened by such Guarantor; and (v) to do all other things which Agent is
permitted to do under this Agreement or any Guaranty Documents or which are
necessary to carry out this Agreement and the Guaranty Documents.  Neither Agent
nor any of its directors, officers, employees or agents will be liable for any
acts of commission or omission nor for any error in judgment or mistake of fact
or law, unless the same shall have resulted from gross negligence or willful
misconduct.  The foregoing appointment and power, being coupled with an
interest, is irrevocable until all Obligations under this Agreement are paid and
performed in full and this Agreement, the Guaranty Documents, and the Loan
Agreement are each terminated.  Each Guarantor expressly waives presentment,
demand, notice of dishonor and protest of all instruments and any other notice
to which it might otherwise be entitled.

          (f) If any Guarantor's Account Receivable or Contract Right, in either
case in excess of $2,000,000, and designated by Borrower as an Eligible Account,
arises out of a contract with the United States or any state or local
governmental entity, or any department, agency, or instrumentality thereof, such
Guarantor will immediately notify Agent in writing and execute any instruments
and take any steps reasonably required by Agent in order that all monies due and
to become due under such contract shall be assigned to Agent, for the benefit of
itself and Lenders, and notice thereof given to the applicable government under
the Federal Assignment of Claims Act of 1940, as amended, or other applicable
laws or regulations, provided, that with respect to such Accounts Receivable and
Contract Rights in existence on the Closing Date or within 90 days thereafter,
such steps need not be completed until 90 days after the Closing Date.  The
failure of a Guarantor to comply with this clause (f) shall not by itself
                                           ----------                    
constitute a Default; rather, such failure will cause the applicable Account
Receivable or Contract Right to be deemed not to be an Eligible Account under
the Loan Agreement.

          (g) If any Guarantor's Account Receivable or Contract Right is
evidenced by chattel paper or promissory notes, trade acceptances, or other
instruments for the payment of money, such Guarantor will, unless Agent shall
otherwise agree, deliver the originals of same to Agent, appropriately endorsed
to Agent's order and, regardless of the form of such endorsement, such Guarantor
hereby expressly waives presentment, demand, notice of dishonor, protest and
notice of protest and all other notices with respect thereto.

          2.3  Inventory
               --------- 

          (a) Each Guarantor warrants and covenants that:  (i) all of the
Inventory is, and at all times shall be, owned by such Guarantor free of all
claims and Liens (except as set forth in Section 5.15 of the Loan Agreement);
                                         ------------                        
and no Guarantor will make any further assignment of any thereof or create or
permit to exist any

                                      -6-
<PAGE>
 
further Lien thereon, unless approved in writing by Requisite Lenders, nor
permit any of Agent's rights therein to be affected by any attachment, levy,
garnishment or other judicial process.

          (b) Neither Agent nor any Lender shall be liable or responsible in any
way for the safekeeping of any Inventory delivered to it, to any bailee
appointed by or for it, to any warehouseman, or under any other circumstances,
other than for losses caused by its gross negligence or willful misconduct.
Neither Agent nor any Lender shall be responsible for collection of any proceeds
or for losses in collected proceeds held by any Guarantor in trust for Agent.
Any and all risk of loss for any or all of the foregoing shall be upon
Guarantors.

          (c) Any material change in the value or condition of any Inventory,
and any errors discovered in any monthly inventory certificate under Section
                                                                     -------
5.1.3 of the Loan Agreement or any other inventory schedule delivered to Agent
-----                                                                         
and Lenders, shall be reported to Agent promptly.  Each Guarantor represents and
warrants that, as to each schedule of Inventory delivered by Borrower to Agent
or any Lender:

          (i) The descriptions, origins, sizes, qualities, quantities,
     weights, and markings of all of such Guarantor's goods stated thereon, or
     on any attachment thereto, are true and correct in all respects;

         (ii)  None of such Guarantor's goods are defective, of second
     quality, used, or goods returned after shipment, except where described as
     such; and

        (iii)  All of such Guarantor's Inventory not included on such
     schedule has been previously scheduled.

          2.4  Supplemental Documentation.  At Agent's request, each Guarantor
               --------------------------                                     
shall execute and deliver, or cause to be executed and delivered, to Agent, at
any time or times hereafter, such agreements, documents, financing statements,
warehouse receipts, bills of lading, notices of assignment of Accounts
Receivable, schedules of Accounts Receivable assigned, and other written matter
necessary or reasonably requested by Agent to perfect and maintain perfected
Agent's security interest in the Collateral, for the benefit of itself and
Lenders (all the above hereinafter referred to as "Supplemental Documentation"),
in form and substance acceptable to Agent, and pay all taxes, fees and other
costs and expenses associated with any recording or filing of the Supplemental
Documentation.  Each Guarantor hereby irrevocably makes, constitutes and
appoints Agent (and all Persons designated by Agent for that purpose) as such
Guarantor's true and lawful attorney (and agent-in-fact) (which appointment and
power, being coupled with an interest, is irrevocable until the last to occur of
termination of this Agreement and the Guaranty Documents, termination of the
Loan Agreement, and payment and performance in full of all of the

                                      -7-
<PAGE>
 
Obligations under this Agreement) to sign the name of such Guarantor on any of
the Supplemental Documentation and to deliver any of the Supplemental
Documentation to such Persons as Agent in its sole and absolute discretion, may
elect.  Each Guarantor agrees that a carbon, photographic, photostatic, or other
reproduction of this Agreement or of a financing statement is sufficient as a
financing statement.

          2.5  Collateral for the Benefit of Agent and Lenders.  All Liens
               -----------------------------------------------            
granted to Agent hereunder and under the Guaranty Documents and all Collateral
delivered to Agent hereunder and under the Guaranty Documents shall be deemed to
have been granted and delivered to Agent, for the benefit of itself and Lenders,
to secure the Obligations.

          2.6  Certain Intellectual Property.  Each Guarantor hereby grants
               -----------------------------                               
Agent, for the benefit of Lenders, a world-wide irrevocable license or other
right to use, without charge, labels, rights of use of any name, tradenames,
trademarks and advertising matter, or any assets and property of a similar
nature (collectively, the "Intangible Rights"), as they pertain to the
Collateral, in advertising for sale and selling any Collateral and such
Guarantor's rights under all applicable licenses and license agreements related
to the foregoing shall inure to Agent's benefit.  Such license shall remain in
full force and effect until all of the Obligations  have been repaid in full.
Any transfer of or Lien on the Intangible Rights granted by any Guarantor to any
other Person shall be subject in all respects to Agent's rights granted
hereunder.

          3.  REPRESENTATIONS AND WARRANTIES.
              ------------------------------ 

          Each Guarantor hereby makes with respect to itself those

     or all of the Collateral (in addition to Collateral which it may already
     have in its possession), wherever it may be found, and for that purpose may
     pursue the same wherever it may be found, and may enter into any premises

     take possession of,remove, keep and store any of the Collateral until the

     constructively in its possession at public or private sale and apply the
     proceeds thereof as provided below.

               -----------------------------------                      
intended disposition of any of the Collateral required by law shall be deemed
reasonably and properly given if given at least ten (10) calendar days before
such disposition.

          5.4  Application of Proceeds of Collateral.  Any proceeds of any
               -------------------------------------

reasonable care in the custody and preservation of a Guarantor's Collateral in
its possession if it takes such action for that purpose as such Guarantor
requests in writing, but failure of Agent to comply with such request shall not,
of itself, be deemed a failure to exercise reasonable care, and no failure of
Agent to preserve or protect any rights with respect to such Collateral against
prior parties, or to do any act with respect to the preservation of such
Collateral not so requested by such Guarantor, shall be deemed a failure to
exercise reasonable care in the custody or preservation of such Collateral.

faithfully serve the Company, shall in all respects conform to and comply with
the lawful and reasonable directions and instructions given to him by the Board

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

performance of his duties hereunder in accordance with the Company's
reimbursement policies in effect on the date hereof.

          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 this Agreement
for an aggregate of one hundred twenty (120) 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 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 for 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 sixty (60)
days during any 12-month period during the term of this Agreement.

                                       5
<PAGE>
 
          (c) Just Cause.  The Company may terminate this Agreement (other than
              ----------
Sections 7, 8, 9 and 12 hereof) for "Just Cause."  For purposes of this
                                     ----------
Agreement, "Just Cause" shall mean: (i) the Executive's willful and continued
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 specifically set forth the
nature of said failure, neglect or refusal; (ii) any willful or intentional
engagement by the Executive in misconduct (including repeated drunkenness or use
of illegal drugs) 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) any
continued or repeated absence from the Company, unless such absence is (A)
approved or excused by the Board of Directors or (B) is the result of the
Executive's physical or mental disability (in which event the provisions of
Section 6(b) hereof shall control) or a personal or family emergency; (iv)
conviction of the Executive for the commission of a felony; or (v) the
commission by the Executive of an act of fraud or embezzlement against the
Company. If the Executive's employment is terminated for Just 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 specifically set forth the nature of
the Just 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 

                                       6
<PAGE>
 
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
benefit plans as provided in Section 3(c) hereof; (iii) any material
diminishment in the duties or responsibilities of the Executive described in
Section 1, or any removal of the Executive from or any failure to re-elect the
Executive to (x) the positions described in Section 1, except in connection with
promotions to higher office, or (y) the position as a director of the company;
(iv) the Company's requiring the Executive to be based anywhere other than in or
within 35 miles of the Executive's current principal place of employment, except
for required travel on the business of the Company to an extent substantially
consistent with the Executive's prior business travel obligations, or, in the
event the Executive consents to relocation, the failure of the Company to pay or
reimburse the Executive for all reasonable costs incurred by the Executive in
connection with such relocation as mutually agreed by the Company and the
Executive prior to such relocation; and (v) the failure of any successor to all
or substantially all of the business and/or assets of the Company to assume this
Agreement; 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
thirty (30) days after receipt by the Company of 

                                       7
<PAGE>
 
written notice of such resignation, provided that any resignation by 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
Just 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 Just 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 Just 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 Just Cause or by the
Executive with Good Reason, in addition to the amounts specified in the 

                                       8
<PAGE>
 
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 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 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 Section 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 past
and current employment with the Company, the Executive has obtained and 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' 

                                       9
<PAGE>
 
substantial detriment. The Executive also acknowledges that GEV and PAAC have
purchased all of the outstanding shares of the Company in reliance on the
covenants made by the Executive in this Section 7, and that they would not have
acquired such shares in the absence of the covenants made by the Executive in
this Section 7. Therefore, the Executive agrees that during the term of this
Agreement and for a period of three years following the date of termination of
the Executive's employment hereunder (the "Restricted Period") the Executive
                                           -----------------
shall not participate or engage, directly or indirectly, for himself or on
behalf of or in conjunction with any person, partnership, corporation or other
entity, whether as an employee, agent, officer, director, shareholder, partner,
joint venturer, investor or otherwise, in any business activities if such
activity consists of the manufacture, processing, marketing, sale, storage and
transport of chorine, caustic soda, muriatic acid, bleach, iron chlorides,
aluminum sulfate, hydrogen and steam and certain other products relating thereto
or the management thereof and all activities necessary therefor or incidental
thereto (the "Chlor Alkali Business"); provided, however, that nothing contained
              ---------------------    --------  -------
in this Section 7(a) shall prohibit or restrict the Executive from making any
investment, for investment purposes only, of up to three percent (3%) of the
stock of any publicly traded entity whose stock is either listed on a national
stock exchange or on the NASDAQ National Market System, provided, further, that
                                                        --------  -------
anything in this Section 7(a) or in Section 7(b) to the contrary
notwithstanding, following termination of this Agreement the Executive shall not
be prohibited from serving as a director, officer, or employee of, or consultant
to, an entity which is engaged in whole or part, in the Chlor Alkali Business so
long as the Executive, at all times during the Restricted Period, does not (i)
initiate contact or solicit, directly or indirectly, those Persons who were
customers of or suppliers to, or who otherwise had business relationships with,
the Company, or any of its respective subsidiaries, at any time during the
twelve month period preceding the date of termination, or (ii) disclose or use
Confidential Information in any manner which would be materially

                                       10
<PAGE>
 
adverse to the Chlor Alkali Business conducted by the Company and its
subsidiaries as of the date of termination.

          (b) Nondisclosure of Confidential Information.  The Executive, except
              -----------------------------------------
in connection with his employment hereunder or as required by legal process,
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 any predecessor to the Company's business 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
owning a duty or 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"); provided, however,
                              ------------------------    --------  -------
that the term Confidential Information shall not include (i) general skills and
general knowledge of an industry obtained by reason of the Executive's
association with the Company; (ii) information concerning the business and
operations of the Company and its subsidiaries and/or the industry in which the
Company and its subsidiaries conduct business which was in the possession of or
known to the Executive prior to the Executive's employment with the Company;

                                       11
<PAGE>
 
and (iii) any financial or other information with respect to the assets,
properties, rights, business or operations of Basic or any of its subsidiaries,
or Victory Valley, or relating to the Subject Parcels (as such terms are defined
in the Purchase Agreement). 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.

          (c) No Interference.  During 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, 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) or who is, or was within the then most recent
twelve-month period, a customer or client of the Company, its predecessors or
any of its subsidiaries or affiliates.

          (d) 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 

                                       12
<PAGE>
 
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(d) unless the Executive bears the burden of proof
of showing that the Invention was first conceived and made following such
termination. Notwithstanding anything contained herein to the contrary, the
Executive shall continue to own the exclusive right, title and interest in and
to any and all inventions, improvements, discoveries, ideas, designs, documents
and other data (whether or not patentable): (A) conceived, made and developed
prior to the date of this Agreement; and (B) irrespective of when conceived,
made or developed, which do not relate to the actual or anticipated business of
the Company or any existing or prior research and development activities of the
Company or any of its subsidiaries.

          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 

                                       13
<PAGE>
 
Section 7 hereof may result in material irreparable injury to the Company or its
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 7 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 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 

                                       14
<PAGE>
 
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 this 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

                             Arbitration Procedures
                             ----------------------

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

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

          (c) Arbitrators are empowered to resolve Disputes by summary rulings
substantially similar to summary judgments and motions to dismiss. Arbitrators
shall resolve all Disputes in accordance with the applicable substantive law.
Any arbitrator selected shall be required to be experienced and knowledgeable in
the substantive laws applicable to the subject matter of the Dispute. With
respect to a Dispute in which the claims or amounts in controversy do not exceed
$100,000, a single arbitrator shall be chosen and shall resolve the Dispute. In
such case, the arbitrator shall be required to make specific, written findings
of fact, and shall have authority to render an award up to but not to exceed
$100,000, including all amounts properly payable and costs, fees and expenses
(subject to Section 17 of the Agreement). A Dispute involving claims or amounts
in controversy exceeding $100,000, shall be decided by a majority vote of a
panel of three (3) arbitrators (an "Arbitration Panel"), the determination of
                                    -----------------
any two (2) of the three (3) arbitrators constituting the determination of the
Arbitration Panel; provided, however, that all three (3)
<PAGE>
 
arbitrators on the Arbitration Panel must actively participate in all hearings
and deliberations. Arbitrators, including any Arbitration Panel, may grant any
remedy or relief deemed just and equitable and within the scope of these
arbitration provisions and may also grant such ancillary relief as is necessary
to make effective any award. Arbitration Panels shall be required to make
specific, written findings of fact and conclusions of law, and in such
proceedings before an Arbitration Panel only, the parties shall have the
additional right to seek vacation or modification of any award of an Arbitration
Panel that is based in whole, or in part, on an incorrect or erroneous ruling of
law by appeal to a Federal or State Court of Appeals, following the entry of
judgment on the award in Federal or State District Court, as appropriate. For
these purposes, the award and judgment entered by the Federal or State District
Court shall be considered to be the same as the award and judgment of the
Arbitration Panel. All requirements applicable to appeals from any Federal or
State District Court judgment shall be applicable to appeals from judgments
entered on decisions rendered by Arbitration Panels. The Appellate Courts shall
have the power and authority to vacate or modify an award based upon a
determination that there has been an incorrect or erroneous ruling of law. The
Appellate Court shall also have the power to reverse and/or remand the decision
of an Arbitration Panel. Subject to the foregoing, the determination of an
arbitrator or Arbitration Panel shall be binding on all parties and shall not be
subject to further review or appeal except as otherwise allowed by applicable
law.

          (d) To the maximum extent practicable, the AAA, the arbitrator (or the
Arbitration Panel, as appropriate) and the parties shall take any action
necessary to require that an arbitration proceeding hereunder shall be concluded
within one hundred eighty (180) days of the filing of the Dispute with the AAA.
Unless the Company and the Executive shall agree otherwise, arbitration
proceedings hereunder shall be conducted in Houston, Texas.  Arbitrators shall
be empowered to impose sanctions and to take such other actions as they deem

                                       2
<PAGE>
 
necessary to the same extent a judge could pursuant to the Federal Rules of
Civil Procedure and applicable law.  With respect to any Dispute, each party
agrees that all discovery activities shall be expressly limited to matters
directly relevant to the Dispute and any arbitrator, Arbitration Panel and the
AAA shall be required to fully enforce this requirement.  The provisions of
these arbitration provisions shall survive any termination, amendment or
expiration of this Agreement, unless the parties otherwise expressly agree in
writing.  To the extent permitted by applicable law, arbitrators, including any
Arbitration Panel, shall have the power to award recovery of all costs and fees
(including attorneys' fees, administrative fees and arbitrators' fees) to the
prevailing party or, if no clear prevailing party, as the arbitrator (or
Arbitration Panel, if applicable) shall deem just and equitable.  Each party
agrees to keep all Disputes and arbitration proceedings strictly confidential,
except for disclosures of information required by applicable law.

                                CONFIDENTIALITY

     Section 6.1 Background.  Employer in the course of its business has
                 ----------
developed valuable technical information and know-how, which information is used
in its business.  The Employee acknowledges that much of the technical
information and know-how developed by Employer is not generally known in the
industry and gives Employer a competitive advantage over those who do not know
it.  As a consequence of and during the course of his employment, the Employee
will have access to, and/or will learn or conceive confidential and/or
proprietary information on Employer's time and at Employer's expense, relating
to Employer's then-current or contemplated interests.  This information is
likely to be of benefit to Employer, in its line of business even after
termination of the Employee's full-time employment.

     Section 6.2 Confidential Information.  The parties recognize that in the
                 ------------------------ 
course of the Employee providing services to Employer, the Employee will have
access to various confidential and/or proprietary business information which
relates to Employer's business and which has commercial or other value
("Confidential Information," defined in more detail below).  As used in this
Agreement, the term "Confidential Information" includes by way of illustration
but without limitation (except as expressly set forth in Section 6.3) any and
all information relating to the services performed or products sold by Employer,
processes therefor, apparatus and maintenance thereof, research, research
programs, processes, program files, flow charts, drawings, techniques,
standards, specifications, improvements, inventions, customer or potential
customer information, accounting data, statistical data, research projects,
development and marketing plans, strategies, forecasts, customer lists, sales
plans and sales and marketing information, and the like that are now in the
possession of or may be acquired by or on behalf of Employer, whether or not
tangibly embodied in a document, model, specimen, computer storage device, or
other physical object, including similar and/or confidential proprietary
information with respect to any subsidiary or related company of Employer.

                                       4
<PAGE>
 

     Section 6.3 Exclusions.  Confidential Information does not include
                 ----------
information that through no breach or fault of the Employee is or becomes (i)
fully described in an English-language printed publication distributed to more
than one hundred (100) persons in the U.S. or Canada; or (ii) disclosed to the
Employee by a third party not having an obligation of confidence to Employer.
All information relating to Employer's business shall be deemed to be
Confidential Information until shown to be within one or more of the foregoing
exceptions.  This Section 6.3 is intended to illustrate but not to limit the
definitions of Confidential Information.  No combination of information shall be
deemed to be within any such exception, whether or not the component parts of
the combination are within one or more exceptions, unless the combination itself
and its economic value and principles of operations are themselves so excepted.

     Section 6.4 Confidential Relationship.  The Employee understands that his
                 -------------------------
position as an employee creates a relationship of confidence and trust between
him and Employer with respect to any Confidential Information which pertains to
Employer's business or to the business of any actual or potential client or
customer of Employer, and which may be learned or developed by the Employee or
made known to him by Employer or any of its clients or customers during the
Employee's employment.

     Section 6.5 Employee's Obligations.  The Employee shall keep all
                 ----------------------
Confidential Information in confidence and trust for the benefit of Employer.
Employee shall not use any Confidential Information except for the benefit of
Employer without the express prior written consent of an authorized officer of
Employer except in the ordinary course of his employment.  Furthermore, the
Employee shall not disclose any Confidential Information to any person or entity
other than Employer and its authorized employees at any time without such
consent.

     Section 6.6  Additional Obligations of Employee.  Upon termination of
                  ----------------------------------
employment, the Employee shall not take with him any drawings, blueprints,
notes, memoranda, specifications, devices, documents, or any other tangible
embodiments of any Confidential Information.

                                  ARTICLE VII.
                                    REMEDIES

     Without limiting other possible remedies to Employer available for breach
of any of the covenants contained in this Agreement, the Employee agrees that
the Employer shall be entitled to damages and to injunctive or other equitable
relief to enforce such covenants, such relief to be without the necessity of
posting a bond, cash or otherwise.

                                 ARTICLE VIII.
                                  TERMINATION

     Section 8.1  Events of Termination.  This Agreement may be terminated:
                  ---------------------
          (a) at any time by Employer for any reason, with or without cause,
              however, Employer shall give Employee prior written notice of
              termination;

          (b) at any time by Employee for any reason, with or without cause,
              however, Employee shall give Employer thirty (30) days notice of
              termination;

          (c) upon the death of the Employee.

     The above notwithstanding, this Agreement shall terminate and have no
effect if the capital stock of Employer is not purchased by Pioneer Americas
Acquisition Corp. or another subsidiary of GEV Corporation on or before April
30, 1995.

     Section 8.2  Effects of Termination.
                  ----------------------
          (a) If this Agreement is terminated by Employer, then Employee shall
be obligated to pay Employee, within ten (10) business days of such termination,
an amount equal to the present value of remaining salary payments due Employee
through April 30, 2000 under Sections 2.1 and 2.2 above, discounted at 7%.

          (b) If this Agreement is terminated by Employee prior to December 31,
1996, then Employer shall continue to pay Employee in accordance with Sections
2.1 and 2.2 above through

                                       6
<PAGE>
 
December 31, 1996, and on December 31, 1996. Employer shall pay Employee an
amount equal to the present value of Employee's salary payments remaining after
December 31, 1996 through April 30, 2000 under Sections 2.1 and 2.2 above,
discounted at 7%. If Employee terminates this Agreement on or after December 31,
1996, the Employer shall pay to Employee, within ten (10) business days of
receiving notice of termination, an amount equal to the present value of
Employee's salary payments remaining after the date of termination through April
30, 2000 under Sections 2.1 and 2.2 above, discounted at 7%.

     All payments by Employer under Section 8.2(a) and (b) are subject to
deductions and withholding as required by law.

     Should this Agreement be terminated because of Employee's death, the
obligations and responsibilities of Employer and Employee hereunder shall
terminate as of the date of Employee's death.  Notwithstanding any of the
foregoing to the contrary, Articles VI, VII and IX shall survive termination of
this Agreement.

                                  ARTICLE IX.
                                  ARBITRATION

     If any dispute shall arise between the Employer and the Employee regarding
Employee's employment by Employer, or the termination thereof, the dispute shall
be settled by arbitration in accordance with applicable California law.  Either
party, by giving written notice to the other party of an intention to invoke an
arbitration proceeding pursuant to this Article IX, may apply to the American
Arbitration Association for an appointment of an arbitrator to be selected from
a list of three (3) arbitrators supplied by the American Arbitration
Association. For a period of five (5) days after the list is delivered to the
Employee and Employer, each shall have the right to strike one name from the
list of arbitrators and the arbitrator not stricken shall be the arbitrator
hereunder. Any party unable or unwilling to strike a name within the period
required shall forfeit his or its right to participate in the selection of the
arbitrator. The arbitrator so selected shall then diligently conduct an
arbitration proceeding in accordance with applicable California law. The
decision of the arbitrator shall be final and

                                       7
<PAGE>
 
conclusive upon the parties, and a judgment upon the award may be entered in any
court having jurisdiction. Each party expressly acknowledges that the other
party has the right to undertake reasonable discovery procedures in connection
with the arbitration proceeding. The party against whom the arbitrator rules
will pay all costs with respect to the arbitration proceeding. Notwithstanding
any of the foregoing to the contrary, the arbitration provisions set forth in
this Article IX shall not apply to any dispute between Employee and Employer
relating to Article VI hereof.

                                   ARTICLE X.
                                 MISCELLANEOUS

     Section 10.1.  Waiver.  The waiver by either party of a breach or violation
                    ------
of any provision of this Agreement will not operate as or be construed to be a
waiver of any subsequent breach hereof.

     Section 10.2.  Notice.  Any notice, request, demand or other communication
                    ------
required, permitted or desired to be given hereunder will be deemed given when
