                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.  ORGANIZATION AND BASIS OF PRESENTATION

     The consolidated balance sheet at September 30, 1999 and the consolidated
statements of operations and cash flows for the periods presented are unaudited
and reflect all adjustments, consisting of normal recurring items, which
management considers necessary for a fair presentation. Operating results for
the first nine months of 1999 are not necessarily indicative of results to be
expected for the year ending December 31, 1999. The consolidated financial
statements include the accounts of Pioneer Companies, Inc. ("PCI") and its
subsidiaries (collectively referred to as the "Company"). All significant
intercompany balances and transactions have been eliminated in consolidation.
All dollar amounts in the tabulations in the notes to the consolidated financial
statements are stated in thousands of dollars unless otherwise indicated.

     The consolidated balance sheet at December 31, 1998 is derived from the
December 31, 1998 audited consolidated financial statements, but does not
include all disclosures required by generally accepted accounting principles,
since certain information and disclosures normally included in the notes to the
financial statements have been condensed or omitted as permitted by the rules
and regulations of the Securities and Exchange Commission. The accompanying
unaudited financial statements should be read in conjunction with the financial
statements contained in the Annual Report on Form 10-K for the year ended
December 31, 1998.

     Net loss per common share is computed using the weighted average number of
common shares outstanding during the period. Per share information for 1998 has
been computed after giving retroactive effect to a 7% stock dividend on Class A
and Class B Common Stock to stockholders of record in December 1998.

2.  SUPPLEMENTAL CASH FLOW INFORMATION

     Net effect of changes in operating assets and liabilities are as follows:

4.  COMMITMENTS AND CONTINGENCIES

     The Company and its operations are subject to extensive United States and
Canadian federal, state, provincial and local laws, regulations, rules and
ordinances relating to pollution, the protection of the environment and the
release or disposal of regulated materials. The operation of any chemical
manufacturing plant and the distribution of chemical products entail certain
obligations under current environmental laws. Present or future laws may affect
the Company's capital and operating costs relating to compliance, may impose
cleanup requirements with respect to site contamination resulting from past,
present or future spills and releases and may affect the markets for the
Company's products. The Company believes that its operations are currently in
general compliance with environmental laws and regulations, the violation of
which could result in a material adverse effect on the Company's business,
properties or results of operations on a consolidated basis. There can be no
assurance, however, that material costs will not be incurred as a result of
instances of noncompliance or new regulatory requirements.

     The Company relies on indemnification from the previous owners in
connection with certain environmental liabilities at its chlor-alkali plants and
other facilities. There can be no assurance, however, that such indemnification
arrangements will be adequate to protect the Company from environmental
liabilities at these sites or that such third parties will perform their
obligations under the respective indemnification arrangements, in which case the
Company would be required to incur significant expenses for environmental
liabilities, which would have a material adverse effect on the Company.

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

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 consolidated financial statements and the related notes thereto.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1998

     Revenues. Revenues decreased by $25.5 million or approximately 25% to $74.9
million for the three months ended September 30, 1999, as compared to the three
months ended September 30, 1998. The decrease in revenues was primarily
attributable to lower electrochemical unit ("ECU") prices. ECU prices were
approximately 28% lower during the third quarter of 1999 versus the third
quarter of 1998, which caused approximately a $19 million decrease in revenues.
The remaining revenue decrease was primarily due to the disposal of the
company's household bleach bottling business during the third quarter of 1998,
the disposal of the pool chemicals business in the fourth quarter of 1998 and
the disposal of the iron chlorides business in the first quarter of 1999. These
businesses were considered non-strategic, and the Company retained long-term
supply agreements with the purchasers.

     Cost of Sales. Cost of sales decreased $5.3 million or approximately 7% for
the three months ended September 30, 1999, as compared to the same period in
1998, which was principally due to the disposed operations discussed above.

     Gross Profit (Loss). During the third quarter of 1999 the Company incurred
a gross loss on revenues, as a result of the low ECU sales prices.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $0.4 million for the three months ended
September 30, 1999, as compared to the same period in 1998. During September
1999, the Company replaced its existing revolving credit facility with a new
three-year $50 million revolving credit facility. The $0.4 million of
unamortized capitalized financing costs relating to the previous credit facility
were expensed.

     Interest Expense, Net. Interest expense, net increased $0.5 million in
1999, as compared to the same period in 1998. Interest income was less during
the third quarter of 1999 due to a reduction in cash balances.

     Other Income (Expense), Net. Other income in the third quarter of 1999
included transportation credits of approximately $1.8 million and the receipt of
$0.6 million in distributions arising from the Company's 15% partnership
interest in Saguaro Power Company.

     Net Loss. Due to the factors described above, the Company incurred a net
loss of $14.6 million during the three months ended September 30, 1999, as
compared to a net loss of $4.3 million during the same period in 1998.


NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1998

     Revenues. Revenues decreased by $89.8 million or approximately 29% to
$214.9 million for the nine months ended September 30, 1999, as compared to the
nine months ended September 30, 1998. ECU prices were approximately 33% lower
during the 1999 period, versus the 1998 period, which caused approximately $69
million of the decrease. The remaining revenue decrease was primarily the result
of the disposal of the various operations discussed above.

     Cost of Sales. Cost of sales decreased $27.5 million, or approximately 12%,
for the nine months ended September 30, 1999, as compared to the same period in
1998. $10.9 million of this decrease was due to the modification of the
Company's retiree health care benefits. Benefits under the plan to current
retirees were not impacted, but current employees will no longer receive
benefits under this plan. The remaining decrease in cost of sales was
principally due to lower cost of as a result of the disposed operations.

     Gross Profit. Gross profit margin decreased to 6% in 1999 from 24% in 1998,
primarily as a result of the ECU price decreases.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses decreased by $5.6 million, or approximately 14%, for the
nine months ended September 30, 1999. $1.6 million of this decrease was due to
the modification



                                       8
<PAGE>   9

of the Company's retiree health care benefits discussed above. $2.8 million of
the decrease was related to the absence of incentive compensation accruals
during 1999. The remaining decrease was related to overhead expense reductions.

     Interest Expense, Net. Interest expense, net increased in 1999 as a result
of decreased interest income due to lower average cash balances in 1999.

     Other Income (Expense), Net. Other income (expense), net decreased from
income of $2.2 million for the nine months ended September 30, 1998 to income of
$1.6 million for the nine months ended September 30, 1999. The other income in
1999 included transportation credits of approximately $1.8 million and the
receipt of $0.6 million in distributions arising from the Company's 15%
partnership interest in Saguaro Power Company, partially offset by a loss from
the sale of the iron chlorides business of approximately $1.2 million. 1998's
other income included a gain from the settlement of a lawsuit, an insurance
recovery and a state franchise tax refund.

     Net Loss. Due to the factors described above, there was a net loss of $38.9
million for the nine months ended September 30, 1999, compared to a net loss of
$2.4 million for the same period in 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Revolving Facility. In September 1999, the Company entered into a $50.0
million three-year revolving credit facility with Congress Financial Corporation
(Southwest) (the "Revolving Facility") that replaced an existing $50.0 million
revolving facility. The Revolving Facility provides for revolving loans in an
aggregate amount up to $50.0 million, subject to borrowing base limitations
related to the level of accounts receivable and inventory, which, together with
certain other collateral, secure borrowings under the facility. The total
borrowing base at September 30, 1999 of $39.4 million was subject to a reserve
of $5.0 million until the Company's ratio of interest to fixed charges, as
defined, exceeds 1.15:1 for a period of two consecutive quarters. As of
September 30, 1999, there were letters of credit outstanding of $4.5 million
(excluding transitional letters of credit of $2.6 million) and loans outstanding
of $3.3 million.

     Financial Leverage and Covenants. As of September 30, 1999, the Company had
$588.2 million of long-term debt outstanding. While the majority of the
Company's debt is due in 2006 and 2007, the Company is required to make certain
scheduled payments each year. The degree to which the Company is indebted could
have important consequences including, but not limited to: (i) limitations on
the ability to obtain additional financing in the future for working capital,
capital expenditures, general corporate purposes and other purposes, if needed;
(ii) the allocation of a substantial portion of cash flow from operations to
cover cash interest requirements, thereby limiting the funds available for
operations and any future business opportunities; and (iii) increasing the
Company's vulnerability to a downturn in its business or the economy.

     PCI's cash requirements include quarterly payments of interest on $11.5
million of long-term debt. PCI's subsidiary, Pioneer Americas, Inc. ("PAI"), is
restricted in paying dividends to PCI or funding cash to unrestricted
subsidiaries, as defined, to the sum of $5.0 million plus 50% of the cumulative
consolidated net income of PAI since June 1997. As of September 30, 1999, no
distributions were allowed under this covenant. However, the Company believes
that the existing cash balances of PCI and its unrestricted subsidiaries will be
sufficient to fund future required interest payments and other cash requirements
until such time that PAI's cumulative consolidated net income is positive.

     PAI's ability to enter into new debt agreements is restricted by a debt
covenant requiring a minimum interest coverage ratio (as defined) of at least
2.0 to 1.0 for the prior four fiscal quarters. Currently, PAI is unable to incur
additional indebtedness as a result of this covenant, other than borrowing
available under the Revolving Facility. The Company's debt agreements contain
other restrictions on PAI's subsidiaries, including the acquisition or
disposition of assets or operations.

     Annualized cash interest of approximately $51.5 million is payable on the
Company's long-term debt. To the extent that the Company makes additional draws
upon the Revolving Facility due to continuing adverse business conditions or for
other corporate purposes, the Company's aggregate interest expense will be
increased.

     Business Conditions. Recent industry capacity additions have created an
imbalance between product demand and supply, resulting in weak market conditions
and lower ECU sales prices. During 1999, ECU sales prices have been at their
lowest level in twenty-five years. These lower sales prices generated decreased
sales revenues, negative sales margins, continuing losses from operations and
significant decreases in working capital, primarily cash balances.

     Chlorine and caustic soda sales prices have recently increased, indicating
that the bottom of the current industry cycle may have passed. Improved business
conditions would result in higher sales levels and improved cash flow. If a
recovery has not commenced, the Company would expect a continuation of depressed
sales levels, significant losses and continued usage of cash for operations. The
Company currently has availability under the Revolving Facility to fund
continuing operations.



                                       9

     Foreign Operations and Exchange Rate Fluctuations. The Company has
operating activities in Canada and engages in export sales to various countries.
International operations and exports to foreign markets are subject to a number
of risks, including currency exchange rate fluctuations, trade barriers,
exchange controls, political risks and risks of increases in duties, taxes and
governmental royalties, as well as changes in laws and policies governing
foreign-based companies. In addition, earnings of foreign subsidiaries and
intracompany payments are subject to foreign taxation rules.

     A portion of the Company's sales and expenditures are denominated in
Canadian dollars, and accordingly, the Company's results of operations and cash
flows may be affected by fluctuations in the exchange rate between the United
States dollar and the Canadian dollar. Currently, the Company is not engaged in
forward foreign exchange contracts, but may enter into such hedging activities
in the future.

     Net Cash Flows from Operating Activities. During the first nine months of
1999, the Company had a negative cash flow of $26.4 million from operating
activities, primarily attributable to the net loss for the period.

     Net Cash Flows from Investing Activities. Cash used in investing activities
during the first nine months of 1999 totaled $22.4 million, which was due to
capital expenditures related to property, plant and equipment, partially offset
by proceeds received from asset disposals.

     Net Cash Flows from Financing Activities. Cash provided by financing
activities during the first nine months of 1999 included $3.3 million of net
borrowings under the revolving credit arrangement, offset by $2.0 million of
debt repayments.

     Working Capital. Working capital decreased to $9.9 million at September 30,
1999 from $64.7 million at December 31, 1998, a decrease of $54.8 million. Usage
of cash for operating activities and capital expenditures primarily accounted
for this decrease.

YEAR 2000 ISSUES

         Based on present information, management believes that the potential
impact of the year 2000 on the processing of date-sensitive data by the
Company's critical business systems, including process control systems, have
been addressed. The year 2000 may be critical to these systems as some computer
programs were written using two digits rather than four to define the applicable
year. As a result, any of the Company's computer applications that have
date-sensitive programs may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in process system failures in the
manufacturing area that could cause serious production-related issues. In
addition, miscalculations or system failures could result in a temporary
inability to process transactions, issue invoices, remit payments, communicate
with financial institutions and other entities electronically and update
internal accounting systems. If not corrected in a timely manner, such business
disruptions could be detrimental to the continuing operations of the Company.

     The Company initiated a program almost two years ago to prepare its
computer systems and applications for the year 2000. The Company utilized both
internal and external resources to reprogram or replace existing business
critical systems for year 2000 compliance. Where appropriate, critical systems
were tested to verify year 2000 compliance. The total project costs, including
costs already expended, are presently estimated at approximately $0.5 million.
These funds, the majority of which have been spent, are being obtained through
working capital, and are being expensed as incurred unless new software is
purchased in which case certain costs are capitalized.

     The Company has taken steps to identify year 2000 compliance issues that
may be created by key customers, suppliers and financial institutions with which
the Company does business. While no single customer represents greater than 10%
of the Company's revenues, the Company does have several large customers who
each account for a sizable dollar amount of sales revenue. The Company's
significant vendors include electrical power companies, salt companies and
freight companies. The loss of any key customer or the inability of any of the
Company's key vendors to provide its goods and services to the Company would
have a negative impact on the Company's operations until those entities return
to normal operations.

     The Company has developed written contingency plans to address the issues
that could arise should the Company or any of its significant suppliers,
customers or financial institutions not be prepared to accommodate year 2000
issues timely. Where practical, alternate key suppliers have been identified to
minimize supplier interruption problems. In addition, the Company believes that
in an emergency situation it could revert in many cases to the use of manual
systems that do not rely on computers. Through these manual systems, the Company
could perform the minimum functions required to maintain the flow of goods and
provide a minimum level of information reporting to maintain a level of control
over the business cycle. However, should the Company have to utilize manual
systems, it is uncertain that it could maintain current levels of operations and
this could have a material adverse impact on the business.



                                       10
<PAGE>   11

         Between now and the beginning of the year 2000, the Company intends to
maintain constant surveillance on the year 2000 issues and will adapt its plans
as required. The Company will continue to refine the existing contingency plans.
During the remainder of 1999, year 2000 remediation efforts and compliance
testing will be done on some systems which were either determined not to be
essential to the operation of the business and/or adequate work-around
alternatives were identified.

ACCOUNTING CHANGES

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS No. 133"). SFAS No. 133 establishes accounting
and reporting standards for derivative instruments and for hedging activities.
The Company is required to adopt the provisions of SFAS No. 133 in 2001.
Management is currently evaluating the impact of SFAS No. 133 on its financial
statements and related disclosures.


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     In September 1999, the Company replaced its existing $50.0 million
revolving facility with a new $50.0 million three-year revolving credit
facility. The Company's market risk disclosures set forth in the Company's
Annual Report on Form 10-K for the year ended December 31, 1998 have not changed
significantly as a result of the new revolving credit facility or other events
through the nine months ended September 30, 1999.

SECTION 2. CREDIT FACILITIES

     2.1 Loans.

         (a Subject to and upon the terms and conditions contained herein, US
Lender agrees to make US Dollar Loans to US Borrowers from time to time in
amounts requested by any US Borrower or on its behalf by PAI, and Canadian
Lender agrees to make Canadian Dollar Loans and US Dollar Loans to Canadian
Borrower, from time to time in amounts (and as to Canadian Dollar Loans in an
aggregate amount based on the US Dollar Equivalent thereof) requested by
Canadian Borrower or on its behalf by PAI, up to the amount equal to:

            (i eighty-five (85%) percent of the US Dollar Equivalent of the Net
Amount of Eligible Accounts of Borrowers, plus

            (ii the lesser of (A) fifty-five (55%) percent of the US Dollar
Equivalent of the Value of Eligible Inventory of Borrowers or (B0 US$20,000,000,
minus

            (iii any Reserves.

         (b Agent may, in its discretion, from time to time, upon not less than
five (5) days' prior notice to any Borrower (or PAI), (i) reduce the lending
formula with respect to Eligible Accounts to the extent that Agent determines in
good faith that the dilution with respect to the Accounts for any period (based
on the ratio of (A) the aggregate amount of reductions in Accounts other than as
a result of payments in cash to (B) the aggregate amount of total sales) has
increased or may be reasonably anticipated to increase above historical levels,
or (ii) reduce the lending formula with respect to Eligible Inventory to the
extent that Agent determines in good faith that: (A) the number of days of the
turnover of the Inventory for any period has increased in any material respect
or (B) the advance rate percentage with respect to Eligible Inventory pursuant
to Section 2.1(a)(ii)(A) shall exceed eighty-five (85%) percent of the Net
Recovery Percentage (in which case the reduction in the advance rate percentage
shall be equal to the amount by which eighty-five (85%) percent of the Net
Recovery Percentage exceeds the advance rate percentage in effect immediately
prior to such reduction), or (C) the nature, quality and mix of the Inventory
has deteriorated in any material respect. The amount of any reduction in


                                       25
<PAGE>   31


any lending formula by Agent pursuant to this Section 2.1(b) shall have a
reasonable relationship to the matter which is the basis for such reduction in
the good faith determination of Agent. To the extent a Reserve shall have been
established which is sufficient to address any event, condition or matter in a
manner satisfactory to Agent in its good faith determination, Agent shall not
exercise its rights under this Section 2.1(b) to reduce the lending formulas to
address such event, condition or matter.

         (c At any time after the date which is six (6) months after the date
hereof, Borrowers may, at their expense, deliver or cause to be delivered to
Agent a then current appraisal as to the Inventory as of a date within thirty
(30) days of the date of such appraisal in form, scope and methodology
reasonably acceptable to Agent and by an appraiser acceptable to Agent,
addressed to Agent and Lenders and upon which Agent and Lenders are expressly
permitted to rely. To the extent that eighty-five (85%) percent of the Net
Recovery Percentage with respect to the Inventory based on such acceptable
current appraisal is greater than fifty-five (55%) percent, effective on the
fifth (5th) Business Day after the receipt by Agent of such appraisal, the
advance rate percentage set forth in Section 2.1(a)(iii)(A) above shall be
increased to the lesser of: (i) the percentage equal to eighty-five (85%)
percent of such Net Recovery Percentage or (ii) sixty (60%) percent.

         (d Except in Agent's discretion, the aggregate US Dollar Equivalent of
the Loans and the Letter of Credit Accommodations outstanding at any time shall
not exceed the Maximum Credit. In the event that the outstanding US Dollar
Equivalent of any component of the Loans, or the aggregate US Dollar Equivalent
of the outstanding Loans and Letter of Credit Accommodations, exceed the amounts
available under the lending formulas, the sublimits for Eligible Inventory set
forth in Section 2.1(a)(ii) above or the Maximum Credit, as applicable, such
event shall not limit, waive or otherwise affect any rights of Agent or Lenders
in that circumstance or on any future occasions and Borrowers shall, upon demand
by Agent, which may be made at any time or from time to time, immediately repay
to Lenders the entire amount of any such excess(es) for which payment is
demanded.

         (e For purposes only of applying the sublimits on Loans based on
Eligible Inventory pursuant to Sections 2.1(a)(ii) hereof, Agent and Lenders may
treat the then undrawn amounts of outstanding Letter of Credit Accommodations
for the purpose of purchasing Eligible Inventory as Loans to the extent such
Lender is in effect relying on the Eligible Inventory being purchased with such
Letter of Credit Accommodations. In determining the actual amounts of such
Letter of Credit Accommodations to be so treated for purposes of the sublimits,
the outstanding Loans and Reserves shall be attributed first to any components
of the lending formulas in Section 2.1 that are not subject to such sublimits,
before being attributed to the components of the lending formulas subject to
such sublimits.

     2.2 Letter of Credit Accommodations.

         (a Subject to and upon the terms and conditions contained herein, (i)
at the request of US Borrowers (or PAI on behalf of such Borrowers), US Lender
agrees to provide or arrange for Letter of Credit Accommodations denominated in
US Dollars for the account of such


                                       26
<PAGE>   32


Borrowers containing terms and conditions acceptable to Agent, US Lender and the
issuer thereof and (ii) at the request of Canadian Borrower (or PAI on behalf of
such Borrower), Canadian Lender agrees to provide or arrange for Letter of
Credit Accommodations denominated in US Dollars or Canadian Dollars for the
account of such Borrower containing terms and conditions acceptable to Agent,
Canadian Lender and the issuer thereof. Any payments made by Agent or any Lender
to any issuer thereof and/or related parties in connection with the Letter of
Credit Accommodations shall constitute additional Loans to Borrowers pursuant to
this Section 2.

         (b In addition to any charges, fees or expenses charged by any bank or
issuer in connection with the Letter of Credit Accommodations, US Borrowers
shall pay to Agent for the benefit of US Lenders a letter of credit fee in
respect of Letter of Credit Accommodations issued for the account of any US
Borrower or any Guarantor and Canadian Borrower shall pay to Agent for the
benefit of Canadian Lender a letter of credit fee in respect of Letter of Credit
Accommodations issued for the account of Canadian Borrower, in each case at a
rate equal to one and one-half (1 1/2%) percent per annum on the daily
outstanding balance of the Letter of Credit Accommodations issued for the
account of such Borrower for the immediately preceding month (or part thereof),
payable in arrears as of the first day of each succeeding month, except that US
Borrowers shall pay to Agent for the benefit of US Lenders and Canadian Borrower
shall pay to Agent for the benefit of Canadian Lenders such letter of credit
fee, at Agent's option, without notice, at a rate equal to three and one-half
percent (3 1/2%) per annum or such daily outstanding balance for: (i) the period
from and after the date of termination or non-renewal hereof until Agent and
Lenders have received full and final payment of all outstanding and unpaid
Obligations (notwithstanding entry of a judgment against any Borrower) and (ii)
the period from and after the date of the occurrence of an Event of Default and
for so long as such Event of Default is continuing. Such letter of credit fee
shall be calculated on the basis of a three hundred sixty-five (365) day year as
to Letter of Credit Accommodations denominated in Canadian Dollars and a three
hundred sixty (360) day year as to Letter of Credit Accommodations denominated
in US Dollars, and in each case, actual days elapsed and the obligation of
Borrowers to pay such fee as set forth in this Section 2.2(b) shall survive the
termination or non-renewal of this Agreement.

         (c No Letter of Credit Accommodations shall be available unless on the
date of the proposed issuance of any Letter of Credit Accommodations, the Loans
available to Borrowers (subject to the Maximum Credit and any Reserves) are
equal to or greater than: (i) if the proposed Letter of Credit Accommodation is
for the purpose of purchasing Eligible Inventory, the sum of (A) the percentage
equal to one hundred (100%) percent of the US Dollar Equivalent thereof minus
the then applicable percentage set forth in Section 2.1(a)(ii)(A) above
multiplied by the US Dollar Equivalent of the Value of such Eligible Inventory,
plus (B) freight, taxes, duty and other amounts that Agent reasonably estimates
must be paid in connection with such Inventory upon arrival and for delivery to
one of such Borrower's locations for Eligible Inventory within the United States
of America or Canada and (ii) if the proposed Letter of Credit Accommodation is
for any other purpose, an amount equal to one hundred (100%) percent of the US
Dollar Equivalent of the face amount thereof and all other commitments and
obligations made or incurred by Agent or any Lender with respect thereto.
Effective on the issuance of each


                                       27
<PAGE>   33


Letter of Credit Accommodation, a Reserve shall be established in the applicable
amount set forth in Section 2.2(c)(i) or Section 2.2(c)(ii).

         (d Except in the discretion of Agent, the amount of all outstanding
Letter of Credit Accommodations and all other commitments and obligations made
or incurred by Agent or any Lender in connection therewith shall not at any time
exceed US$20,000,000. At any time an Event of Default exists or has occurred and
is continuing, upon Agent's request, Borrowers will either furnish cash
collateral to secure the reimbursement obligations to the issuer in connection
with any Letter of Credit Accommodations or furnish cash collateral to Agent or
any Lender for the Letter of Credit Accommodations, and in either case, the
Loans otherwise available to Borrowers shall not be reduced as provided in
Section 2.2(c) to the extent of such cash collateral.

         (e Each Borrower shall indemnify and hold Agent and Lenders harmless
from and against any and all losses, claims, damages, liabilities, costs and
expenses suffered or incurred by Agent or a Lender in connection with any Letter
of Credit Accommodations and any documents, drafts or acceptances relating
thereto, including, but not limited to, any losses, claims, damages,
liabilities, costs and expenses due to any action taken by any issuer or
correspondent with respect to any Letter of Credit Accommodation, except for the
gross negligence or wilful misconduct of Agent or any Lender as determined
pursuant to a final non-appealable order of a court of competent jurisdiction.
Each Borrower assumes all risks with respect to the acts or omissions of the
drawer under or beneficiary of any Letter of Credit Accommodation and for such
purposes the drawer or beneficiary shall be deemed such Borrower's agent. Each
Borrower assumes all risks for, and agrees to pay, all foreign, Federal, State,
provincial and local taxes, duties and levies relating to any goods subject to
any Letter of Credit Accommodations or any documents, drafts or acceptances
thereunder. Each Borrower hereby releases and holds Agent and Lenders harmless
from and against any acts, waivers, errors, delays or omissions, whether caused
by such Borrower, by any issuer or correspondent or otherwise with respect to or
relating to any Letter of Credit Accommodation except for Agent's or such
Lender's own gross negligence or wilful misconduct as determined pursuant to a
final non-appealable order of a court of competent jurisdiction. The provisions
of this Section 2.2(e) shall survive the payment of the Obligations and the
termination or non-renewal of this Agreement.

         (f Nothing contained herein shall be deemed or construed to grant
Borrowers or Guarantors any right or authority to pledge the credit of Agent or
Lenders in any manner. Agent and Lenders shall have no liability of any kind
with respect to any Letter of Credit Accommodation provided by an issuer unless
such Lender (or Agent on behalf of such Lender) has duly executed and delivered
to such issuer the application or a guarantee or indemnification in writing with
respect to such Letter of Credit Accommodation. Borrowers and Guarantors shall
be bound by any interpretation made in good faith by Agent, or any other issuer
or correspondent under or in connection with any Letter of Credit Accommodation
or any documents, drafts or acceptances thereunder, notwithstanding that such
interpretation may be inconsistent with any instructions of Borrowers and
Guarantors. Agent shall have the sole and exclusive right and authority to, and
Borrowers and Guarantors shall not: (i) at any time an Event of Default exists
or has occurred, (A) approve or resolve any questions of non-compliance of
documents, (B) give any instructions as to acceptance or rejection of any
documents or goods or (C) execute any and


                                       28
<PAGE>   34


all applications for steamship or airway guaranties, indemnities or delivery
orders, and (ii) at all times, (A) grant any extensions of the maturity of, time
of payment for, or time of presentation of, any drafts, acceptances, or
documents, and (B) agree to any amendments, renewals, extensions, modifications,
changes or cancellations of any of the terms or conditions of any of the
applications, Letter of Credit Accommodations, or documents, drafts or
acceptances thereunder or any letters of credit included in the Collateral.
Agent may take such actions either in its own name or in any Borrower's or
Guarantor's name.

         (g) Any rights, remedies, duties or obligations granted or undertaken
by any Borrower to any issuer or correspondent in any application for any Letter
of Credit Accommodation, or any other agreement in favor of any issuer or
correspondent relating to any Letter of Credit Accommodation, shall be deemed to
have been granted or undertaken by such Borrower or Guarantor to Agent and
Lenders. Any duties or obligations reasonably undertaken by Agent or any Lender
to any issuer or correspondent in any application for any Letter of Credit
Accommodation, or any other agreement by Agent or any Lender in favor of any
issuer or correspondent relating to any Letter of Credit Accommodation, shall be
deemed to have been undertaken by Borrowers and Guarantors to Agent or such
Lender and to apply in all respects to Borrowers and Guarantors.

        2.3 Joint and Several Liability. All US Borrowers shall be liable for
all amounts due to Agent and Lenders under this Agreement, regardless of which
US Borrower actually receives the Loans or Letter of Credit Accommodations
hereunder or the amount of such Loans received or the manner in which Agent or
US Lender accounts for such Loans, Letter of Credit Accommodations or other
extensions of credit on its books and records. The Obligations with respect to
Loans made to a US Borrower, and the Obligations arising as a result of the
joint and several liability of a US Borrower hereunder, with respect to Loans
made to the other US Borrowers hereunder, shall be separate and distinct
obligations, but all such other Obligations shall be primary obligations of all
US Borrowers. The Obligations arising as a result of the joint and several
liability of a US Borrower hereunder with respect to Loans, Letter of Credit
Accommodations or other extensions of credit made to the other US Borrowers
hereunder shall, to the fullest extent permitted by law, be unconditional
irrespective of (a) the validity or enforceability, avoidance or subordination
of the Obligations of the other US Borrowers or of any promissory note or other
document evidencing all or any part of the Obligations of the other US
Borrowers, (b) the absence of any attempt to collect the Obligations from the
other US Borrowers, any Guarantor or any other security therefor, or the absence
of any other action to enforce the same, (c) the waiver, consent, extension,
forbearance or granting of any indulgence by Agent or any Lender with respect to
any provisions of any instrument evidencing the Obligations of the other US
Borrowers, or any part thereof, or any other agreement now or hereafter executed
by the other US Borrowers and delivered to Agent, (d) the failure by US Lender
(or Agent on behalf of US Lender) to take any steps to perfect and maintain its
security interest in, or to preserve its rights and maintain its security or
collateral for the Obligations of the other US Borrowers, (e) the election of
Agent or US Lender in any proceeding instituted under the Bankruptcy Code, of
the application of Section 1111(b)(2) of the Bankruptcy Code, (f) the
disallowance of all or any portion of the claim(s) of US Lender for the
repayment of the Obligations of the other US Borrowers under Section 502 of the
Bankruptcy Code, or (g) any


                                       29
<PAGE>   35


other circumstances which might constitute a legal or equitable discharge or
defense of a Guarantor or of the other US Borrowers, other than the wilful
misconduct or gross negligence of US Lender as determined pursuant to a final,
non-appealable order of a court of competent jurisdiction. With respect to the
Obligations arising as a result of the joint and several liability of a US
Borrower hereunder with respect to Loans, Letter of Credit Accommodations or
other extensions of credit made to the other US Borrowers hereunder, each US
Borrower waives, until the Obligations shall have been paid in full and this
Agreement shall have been terminated, any right to enforce any right of
subrogation or any remedy which Agent or US Lender now has or may hereafter have
against US Borrowers, any endorser or any guarantor of all or any part of the
Obligations, and any benefit of, and any right to participate in, any security
or collateral given to Agent or any Lender. Upon any Event of Default and for so
long as the same is continuing, Agent or any Lender may proceed directly and at
once, without notice, against any US Borrower to collect and recover the full
amount, or any portion of the Obligations, without first proceeding against the
other Borrowers or any other Person, or against any security or collateral for
the Obligations. Each US Borrower consents and agrees that Agent or any Lender
shall be under no obligation to marshall any assets in favor of US Borrower(s)
or against or in payment of any or all of the Obligations.

     2.4 Special Availability Reserve.

         (a) Except as Agent may otherwise agree, Agent shall establish a
special Reserve reducing the amount of Loans and Letter of Credit Accommodations
which would otherwise be available to Borrowers in an amount equal to $5,000,000
(the "Special Availability Reserve").

         (b) On the thirtieth (30th) day after the date of receipt by Agent of
the financial statements of PAI and its Subsidiaries with respect to the last
month of any fiscal quarter in accordance with Section 9.6 hereof, the Special
Availability Reserve shall terminate; provided, that, each of the following
conditions are satisfied as of such date: (i) the Fixed Charge Coverage Ratio
for the two (2) full immediately preceding fiscal quarters shall exceed 1.15 to
1.00, (ii) Agent shall have received a certificate of a senior executive officer
of PAI, in form and substance reasonably satisfactory to Agent, certifying to
Agent and Lenders that, based on such financial statements of PAI and its
Subsidiaries received by Agent and Lenders for each of the two (2) full
immediately preceding quarters of PAI and its Subsidiaries, the Fixed Charge
Coverage Ratio for such period exceeds 1.15 to 1.00, and setting forth the
manner of the calculation thereof in such detail and specificity as Agent may
reasonably require, (iii) as of the date of and after giving effect to the
termination of the Special Availability Reserve, no Event of Default, or act,
condition or event which with notice or passage of time or both would constitute
an Event of Default, shall exist or have occurred, and (iv) as of the date of
the termination of the Special Availability Reserve and after giving effect
thereto, the Excess Availability for each of the fifteen (15) days immediately
preceding the termination of the Special Availability Reserve shall have been
not less than $20,000,000.

         (c) Notwithstanding anything to the contrary set forth above, at any
time after the Special Availability Reserve has been terminated, the Special
Availability Reserve may be reestablished if as of the end of any fiscal quarter
either: (i) the Fixed Charge Coverage Ratio for


                                       30
<PAGE>   36


the two (2) full immediately preceding fiscal quarters is equal to or less than
1.15 to 1.00 or (ii) the Excess Availability for each of the fifteen (15) days
immediately preceding the end of such fiscal quarter shall have been equal to or
less than $20,000,000. Upon the reestablishment of the Special Availability
Reserve, it may thereafter be terminated as provided in Section 2.4(b) above and
if it is so terminated then established again pursuant to this Section 2.4(c).


SECTION 3. INTEREST AND FEES

     3.1 Interest.

         (a) Borrowers shall pay to Lenders interest on the outstanding
principal amount of the Obligations (other than the Letter of Credit
Accommodations) at the applicable Interest Rate. All interest accruing hereunder
on and after the date of any Event of Default (and for so long as the same is
continuing) or the effective date of the termination or non-renewal hereof shall
be payable on demand.

         (b) A US Borrower (or PAI on behalf of such Borrowers) may from time to
time request Eurodollar Rate Loans or may request that US Prime Rate Loans be
converted to Eurodollar Rate Loans or that any existing Eurodollar Rate Loans
continue for an additional Interest Period. Such request from or on behalf of a
US Borrower shall specify the amount of the Eurodollar Rate Loans or the amount
of the Eurodollar Rate Loans which will be continued or Prime Rate Loans which
will be converted to Eurodollar Rate Loans (subject to the limits set forth
below), as the case may be, and the Interest Period to be applicable to such
Eurodollar Rate Loans. Subject to the terms and conditions contained herein,
three (3) Business Days after receipt by Agent of such a request from or on
behalf of a US Borrower, such Eurodollar Rate Loans shall be made or US Prime
Rate Loans converted to Eurodollar Rate Loans or such Eurodollar Rate Loans
continued, as the case may be, provided, that, (i) no Event of Default, or act,
condition or event which with notice or passage of time or both would constitute
an Event of Default shall exist or have occurred and be continuing, (ii) no
party hereto shall have sent any notice of termination or non-renewal of this
Agreement, (iii) the Borrower requesting such Eurodollar Rate Loan (or PAI on
behalf of such Borrower) shall have complied with such customary procedures as
are established by Agent and specified by Agent to US Borrowers from time to
time for requests by Borrowers for Eurodollar Rate Loans, (iv) no more than four
(4) Interest Periods may be in effect at any one time, (v) the aggregate amount
of the Eurodollar Rate Loans must be in an amount not less than $3,000,000 or an
integral multiple of $500,000 in excess thereof, and (vi) Agent shall have
determined that the Interest Period or Adjusted Eurodollar Rate is available to
US Lender through the Reference Bank and can be readily determined as of the
date of the request for such Eurodollar Rate Loan by or on behalf of such
Borrower. Any request by or on behalf of a US Borrower to convert US Prime Rate
Loans to Eurodollar Rate Loans or to continue any existing Eurodollar Rate Loans
shall be irrevocable. Notwithstanding anything to the contrary contained herein,
US Lender and Reference Bank shall not be required to purchase United States
Dollar deposits in the London interbank market or other applicable Eurodollar
Rate market to fund any Eurodollar Rate Loans, but the provisions


                                       31
<PAGE>   37


hereof shall be deemed to apply as if US Lender and Reference Bank had purchased
such deposits to fund the Eurodollar Rate Loans.

         (c) Any Eurodollar Rate Loans shall automatically convert to US Prime
Rate Loans upon the last day of the applicable Interest Period, unless Agent has
received and approved a request to continue such Eurodollar Rate Loan at least
three (3) Business Days prior to such last day in accordance with the terms
hereof. Any Eurodollar Rate Loans to a US Borrower shall, at Agent's option,
upon notice by Agent to PAI, convert to US Prime Rate Loans upon the effective
date of the termination or non-renewal of this Agreement. Borrowers shall pay to
Lenders, upon written demand by Agent (or Agent may, at its option, charge any
loan account with respect to a Borrower maintained by Agent as to increase the
outstanding amount of the Loans to such Borrower) any amounts required to
compensate US Lender, the Reference Bank or any Participant with US Lender for
any loss, cost or expense incurred by such person, as a result of the conversion
of Eurodollar Rate Loans to Prime Rate Loans.

         (d) Interest shall be calculated and payable monthly in arrears in the
currency in which such Loans are denominated not later than the first day of
each calendar month and shall be calculated on the basis of (i) a three hundred
sixty-five (365) day year in the case of Canadian Dollar Loans and (ii) a three
hundred sixty (360) day year in the case of US Dollars Loans, and in each case
based on actual days elapsed. The interest rate shall increase or decrease by an
amount equal to each increase or decrease in the Canadian Prime Rate or US Prime
Rate, as applicable, effective on the first day of the month equal to each
increase or decrease in the Canadian Prime Rate or US Dollar Prime Rate, as
applicable, effective on the first day of the month after any such change
occurs. No agreements, conditions, provisions or stipulations contained in this
Agreement or any of the other Financing Agreements or any Event of Default, or
the exercise by Agent or any Lender of the right to accelerate the payment or
the maturity of all or any portion of the Obligations, or the exercise by Agent
or any Lender of any option whatsoever contained in this Agreement or any of the
other Financing Agreements, or the prepayment by or on behalf of any Borrower of
any of the Obligations, or the occurrence of any event or contingency
whatsoever, shall entitle Agent or any Lender to contract for, charge or
receive, in any event, interest exceeding the maximum non-usurious rate of
interest under applicable Federal or State Law as in effect from time to time
that may be contracted for, taken, reserved, charged or received in respect of
Indebtedness of any Borrower to any Lender (the "Maximum Interest Rate"). In no
event shall any Borrower be obligated to pay interest exceeding such Maximum
Interest Rate. All agreements, conditions or stipulations, if any, which may in
any event or contingency whatsoever operate to bind, obligate or compel such
Borrower to pay a rate of interest exceeding the Maximum Interest Rate shall be
without binding force or effect, at law or in equity, to the extent of the
excess of interest over such Maximum Interest Rate. In the event any interest is
contracted for, charged or received in excess of the Maximum Interest Rate
("Excess"), each Borrower acknowledges and stipulates that any such contract,
charge or receipt shall be the result of an accident and bona fide error, and
that any Excess received by Agent or any Lender shall be applied, first, to the
payment of the then outstanding and unpaid principal hereunder; second, to the
payment of the other Obligations then outstanding and unpaid; and third,
returned to such Borrower (or PAI on behalf of such Borrower), it being the
intent of the parties hereto not to enter at any time into a usurious or


                                       32
<PAGE>   38


otherwise illegal relationship. Each Borrower recognizes that, with fluctuations
in the rate of interest set forth in this Section 3.1 and the Maximum Interest
Rate, such an unintentional result could inadvertently occur. By the execution
of this Agreement, each Borrower agrees that (A) the credit or return of any
Excess shall constitute the acceptance by such Borrower of such Excess, and each
Borrower shall not seek or pursue any other remedy, legal or equitable, against
Agent or any Lender, based in whole or in part upon contracting for, charging or
receiving of any interest in excess of the Maximum Interest Rate. For the
purpose of determining whether or not any Excess has been contracted for,
charged or received by Agent or any Lender, all interest at any time contracted
for, charged or received by Agent or any Lender in connection with this
Agreement or any of the other Financing Agreements shall be amortized, prorated,
allocated and spread in equal parts during the entire term of this Agreement.

         (e) For purposes of disclosure under the Interest Act (Canada), where
interest is calculated pursuant thereto at a rate based upon a three hundred
sixty (360) day year or three hundred sixty-five (365) day year (the "First
Rate"), the rate or percentage of interest on a yearly basis is equivalent to
such First Rate multiplied by the actual number of days in the year divided by
three hundred sixty (360) or three hundred sixty-five (365), as applicable.

         (f) Notwithstanding the provisions of this Section 3 or any other
provision of this Agreement, in no event shall the aggregate "interest" (as that
term is defined in Section 347 of the Criminal Code (Canada)) with respect to
any Loans by Canadian Lender exceed the effective annual rate of interest on the
"credit advanced" (as defined therein) lawfully permitted under Section 347 of
the Criminal Code (Canada). The effective annual rate of interest for such
purpose shall be determined in accordance with generally accepted actuarial
practices and principles over the term of the applicable Loan by Canadian
Lender, and in the event of a dispute, a certificate of a Fellow of the Canadian
Institute of Actuaries appointed by Agent will be conclusive for the purposes of
such determination.

         (g) A certificate of an authorized signing officer of Agent as to each
rate of interest payable hereunder from time to time shall be conclusive
evidence of such rate in the absence of manifest error.

         (h) For greater certainty, unless otherwise specified in this Agreement
or any of the other Financing Agreements, as applicable, whenever any amount is
payable under this Agreement or any of the other Financing Agreements by
Borrowers as interest or as a fee which requires the calculation of an amount
using a percentage per annum, each party to this Agreement acknowledges and
agrees that such amount shall be calculated as of the date payment is due
without application of the "deemed reinvestment principle" or the "effective
yield method." As an example, when interest is calculated and payable monthly,
the rate of interest payable per month is one twelfth (1/12) of the stated rate
of interest per annum.

     3.2 Changes in Laws and Increased Costs of Loans.

         (a) Notwithstanding anything to the contrary contained herein, all
Eurodollar Rate Loans shall, upon notice by Agent to a US Borrower (or to PAI on
behalf of such Borrower),


                                       33
<PAGE>   39


convert to US Prime Rate Loans in the event that (i) any change in applicable
law or regulation (or the interpretation or administration thereof) shall either
(A) make it unlawful for US Lender to make or maintain Eurodollar Rate Loans or
to comply with the terms hereof in connection with the Eurodollar Rate Loans (or
for Reference Bank or any Participant to provide the funds to be used by US
Lender to make or maintain Eurodollar Rate Loans or to otherwise enable US
Lender to comply with the terms thereof in connection with Eurodollar Rate
Loans), or (B) shall result in the increase in the costs to US Lender of making
or maintaining any Eurodollar Rate Loans by an amount deemed by US Lender in
good faith to be material (or so increase the costs to Reference Bank or any
Participant of providing the funds used by US Lender to make or maintain
Eurodollar Rate Loans), provided, that, upon the request of a US Borrower (or
PAI on behalf of such Borrower), Eurodollar Rate Loans shall not be converted as
a result of the increase in costs until the end of the applicable Interest
Period with respect to such Eurodollar Rate Loans, so long as Agent and US
Lender shall receive payments from US Borrowers in the amount of such increased
costs and Agent and US Lender shall not otherwise suffer any loss of anticipated
profits, or (C) reduce the amounts received or receivable by US Lender or Agent
in respect thereof, by an amount deemed by US Lender or Agent in good faith to
be material or (ii) the cost to US Lender of making or maintaining any
Eurodollar Rate Loans shall otherwise increase by an amount deemed by US Lender
in good faith to be material (or so increase the costs to Reference Bank or any
Participant of providing the funds used by US Lender to make or maintain
Eurodollar Rate Loans), provided, that, upon the request of a US Borrower (or
PAI on behalf of such Borrower), Eurodollar Rate Loans shall not be converted as
a result of the increase in costs until the end of the applicable Interest
Period with respect to such Eurodollar Rate Loans, so long as Agent and US
Lender shall receive payments from US Borrowers in the amount of such increased
costs and Agent and US Lender shall not otherwise suffer any loss of anticipated
profits. Borrowers shall pay to Agent, within ten (10) days after written demand
by Agent (or Agent may, at its option, charge any loan account with respect to a
Borrower maintained by Agent so as to increase the outstanding amount of the
Loans to such Borrower) any amounts required to compensate Agent, US Lender, the
Reference Bank or any Participant with US Lender for any reasonable loss (other
than loss of anticipated profits), cost or expense incurred by such person as a
result of the foregoing, including, without limitation, any such reasonable
loss, cost or expense incurred by reason of the liquidation or redeployment of
deposits or other funds acquired by such person to make or maintain the
Eurodollar Rate Loans or any portion thereof. A certificate of Agent setting
forth in reasonable detail the basis for the determination of such amount
necessary to compensate Agent, Lenders, Reference Bank or such Participant as
aforesaid shall be delivered to a Borrower (or to PAI on behalf of Borrowers),
together with the written demand referred to in the preceding sentence, and
shall be conclusive, absent manifest error.

         (b) If any payments or prepayments in respect of the Eurodollar Rate
Loans are received by Agent or US Lender other than on the last day of the
applicable Interest Period (whether pursuant to acceleration, upon maturity or
otherwise), including any payments pursuant to the application of collections
under Section 6.3 or any other payments made with the proceeds of Collateral,
Borrowers shall pay to Agent, within ten (10) days after written demand by Agent
(or Agent may, at its option, charge any loan account with respect to a Borrower
maintained by Agent so as to increase the outstanding amount of the Loans to
such Borrower) any amounts required to compensate US Lender, the Reference Bank
or any Participant with US Lender for


                                       34
<PAGE>   40


any reasonable loss (other than loss of anticipated profits), cost or expense
incurred by such person as a result of such prepayment or payment, including,
without limitation, any loss, cost or expense incurred by reason of the
liquidation or redeployment of deposits or other funds acquired by such person
to make or maintain such Eurodollar Rate Loans or any portion thereof. A
certificate of Agent setting forth in reasonable detail the basis for the
determination of such amount necessary to compensate Agent, Lenders, Reference
Bank or such Participant as aforesaid shall be delivered to a Borrower (or PAI
on behalf of Borrowers), together with the written demand referred to in the
preceding sentence, and shall be conclusive, absent manifest error.

     3.3 Fee Letter. Borrowers agree to pay to Agent for the benefit of
Lenders as set forth therein the fees and other amounts set forth in the Fee
Letter, dated of even date herewith, by Borrowers and Agent, in the amounts and
at the times specified therein.

SECTION 6. COLLECTION AND ADMINISTRATION

     6.1 Borrowers' Loan Accounts. Agent shall maintain one or more loan
account(s) on its books in which shall be recorded (a) all Loans, Letter of
Credit Accommodations and other Obligations and the Collateral, (b) all payments
made by or on behalf of Borrowers and (c) all other appropriate debits and
credits as provided in this Agreement, including, without limitation, fees,
charges, costs, expenses and interest. All entries in the loan account(s) shall
be made in accordance with Agent's customary practices as in effect from time to
time.

         6.2 Statements. Agent shall render to PAI, as agent for Borrowers, each
month a statement setting forth the balance in Borrowers' loan account(s)
maintained by Agent for Borrowers pursuant to the provisions of this Agreement,
including principal, interest, fees, costs and expenses. Each such statement
shall be subject to subsequent written adjustment by Agent or any Lender but
shall, absent fraud, mistake or manifest errors or omissions, be considered
correct and deemed accepted by Borrowers and Guarantors and conclusively binding
upon Borrowers and Guarantors as an account stated except to the extent that
Agent receives a written notice from Borrowers of any specific exceptions of
Borrowers thereto within thirty (30) days after the date such statement has been
given by Agent to PAI. In the event of a subsequent written adjustment to any
such statement by Agent, Agent shall notify PAI (as agent for Borrowers) of such
adjustment in writing and such adjustments shall be considered correct and
deemed accepted by Borrowers and Guarantors and conclusively binding upon
Borrowers and Guarantors as an account stated, except to the extent that Agent
receives a written notice from Borrowers of any specific exceptions of Borrowers
thereto within thirty (30) days after the date of notice of such written
adjustment has been given by Agent to PAI. Until such time as Agent shall have
rendered to Borrowers or PAI a written statement as provided above, the balance
in a Borrower's loan account(s) shall be presumptive evidence of the amounts due
and owing to Agent and Lenders by such Borrower.


                                       39
<PAGE>   45

     6.3 Collection of Accounts.

         (a) Subject to the instructions to be delivered to Agent as described
below, each Borrower shall establish and maintain, at its expense, such lockbox
and related blocked accounts ("Blocked Accounts"), as Agent may specify, with
such banks as are reasonably acceptable to Agent. Each Borrower shall direct its
Account Debtors to directly remit to its lockbox all payments on Accounts and
all payments constituting proceeds of Inventory or other Collateral in the
identical form in which such payments are made, whether by cash, check or other
manner. The amounts received in the lockbox of each US Borrower shall be
promptly deposited in a single Blocked Account held in the name of PAI in its
capacity as agent on behalf of US Borrowers. The banks at which the Blocked
Accounts are established shall enter into an agreement, in form and substance
satisfactory to Agent, providing that all items received or deposited in the
Blocked Accounts are the property of Agent and Lenders, that the depository bank
has no lien upon, or right to setoff against, the Blocked Accounts, the items
received for deposit therein, or the funds from time to time on deposit therein
and that the depository bank will wire, or otherwise transfer, in immediately
available funds, on a daily basis, all funds received or deposited into the
Blocked Accounts to such bank account of Agent or any Lender as Agent may from
time to time designate for such purpose ("Payment Account"). Agent shall
promptly instruct the depository banks at which the Blocked Accounts are
maintained to transfer the funds on deposit in the Blocked Accounts to such
operating bank account of Borrowers as PAI may specify in writing to Agent until
such time as Agent shall notify the depository bank otherwise. Agent will only
instruct the depository banks at which the Blocked Accounts are maintained to
transfer all funds received or deposited into the Blocked Accounts to the
Payment Account at any time that either: (i) an Event of Default shall exist or
have occurred and be continuing, or (ii) Excess Availability shall be less than
$15,000,000 and there are Loans or Letter of Credit Accommodations outstanding.
In the event that at any time after Agent has instructed such depository banks
to transfer such funds to the Payment Account, each of the conditions set forth
in clauses (i) and (ii) above do not exist or have not occurred and are not
continuing, upon PAI's written request, Agent shall instruct such depository
banks to transfer the funds on deposit in such accounts to such operating bank
account of Borrowers as PAI may specify in writing to Agent until such time as
Agent is entitled to notify and shall notify the depository bank otherwise as
provided above. Each Borrower agrees that all payments made to such Blocked
Accounts or other funds received and collected by Agent or any Lender, whether
in respect of the Accounts, as proceeds of Inventory or other Collateral or
otherwise shall be treated as payments to Lenders in respect of the Obligations
and therefore shall constitute the property of Lenders to the extent of the then
outstanding Obligations.

         (2) In the event that Agent has notified the depository bank at which
the Blocked Accounts are maintained to transfer the funds therein to the Payment
Account pursuant to Section 6.3(a) above, for the purposes of calculating
interest on the Obligations, such payments or other funds received will be
applied (conditional upon final collection) to the Obligations one (1) Business
Day following the date of receipt of immediately available funds by Agent in the
Payment Account provided such payments or other funds and notice thereof are
received in accordance with Agent's usual and customary practices as in effect
from time to time and within sufficient time to credit such Borrower's loan
account on such day, and if not, then on the next Business Day. For purposes of
calculating the amount of the Loans


                                       40
<PAGE>   46


available to Borrowers, such payments will be applied (conditional upon final
collection) to the Obligations on the Business Day of receipt by Agent of
immediately available funds in the Payment Account provided such payments and
notice thereof are received in accordance with Agent's usual and customary
practices as in effect from time to time and within sufficient time to credit
such Borrower's loan account on such day, and if not, then on the next Business
Day.

         (b) Each Borrower and all of its directors, employees, agents,
Subsidiaries and other Affiliates shall, acting as trustee for Agent and
Lenders, receive, as the property of Lenders, any monies, checks, notes, drafts
or any other payment relating to and/or proceeds of Accounts or other Collateral
which come into their possession or under their control and immediately upon
receipt thereof, shall deposit or cause the same to be deposited in the Blocked
Accounts, or remit the same or cause the same to be remitted, in kind, to Agent.
In no event shall the same be commingled with a Borrower's own funds. Each
Borrower agrees to reimburse Agent and Lenders on demand for any amounts owed or
paid to any bank at which a Blocked Account is established or any other bank or
person involved in the transfer of funds to or from the Blocked Accounts arising
out of Agent or any Lender's payments to or indemnification of such bank or
person in connection with such Blocked Account or any amounts received therein
or transferred therefrom. The obligation of Borrowers to reimburse Agent and
Lenders for such amounts pursuant to this Section 6.3 shall survive the
termination or non-renewal of this Agreement.

         6.4 Payments. All Obligations shall be payable to the Payment Account
as provided in Section 6.3 or such other place as Agent may designate from time
to time. Agent and Lenders may apply payments received or collected from any
Borrower or Guarantor or for the account of any Borrower or Guarantor
(including, without limitation, the monetary proceeds of collections or of
realization upon any Collateral) to such of the Obligations, whether or not then
due, in such order and manner as Agent determines, provided, that, so long as no
Event of Default shall exist or have occurred and be continuing, (a) all such
payments shall be applied to Obligations which are then due and payable before
being applied to pay any Obligations which are not then due and payable; (b) all
such payments shall be applied to Prime Rate Loans before being applied to
Eurodollar Rate Loans; (c) all such payments by Canadian Borrower shall be
applied to pay any Obligations of Canadian Borrower to Canadian Lender,
provided, that, in the event that there are no such Obligations of Canadian
Borrower then outstanding, Agent or Canadian Lender may hold any such payments
as cash collateral for the Obligations on terms and conditions acceptable to
Agent; (d) all such payments by US Borrowers shall be applied to pay any
Obligations of US Borrowers to US Lender, provided, that, in the event that
there are no such Obligations of US Borrowers then outstanding, Agent or US
Lender may hold such payments as cash collateral for the Obligations on terms
and conditions acceptable to Agent; and (e) all payments in respect of the
Obligations of Canadian Borrower shall be applied first to Obligations
denominated in the same currency as the payments received, provided, that, in
the event that there are no such Obligations of Canadian Borrower then
outstanding, Agent or Canadian Lender may hold such payments as cash collateral
for the Obligations on terms and conditions acceptable to Agent. Subject to, and
upon the terms and conditions contained herein, upon the request of a Borrower
(or PAI on behalf of such Borrower), amounts received by Agent from such
Borrower pursuant to the foregoing which are not applied to the Obligations (or
held as cash collateral as provided herein) shall, upon the request of such
Borrower received by Agent, be remitted to such Borrower, provided, that, no
Event of Default, or act, condition or event which with notice or passage of
time or both would constitute an Event of Default, exists or has occurred and is
continuing. All payments received by Agent or any Lender shall be deemed first
applied to Obligations in excess of the limitations on the amount of the
Obligations secured by any item of Collateral pursuant to Section 5.5 hereof.
Payments and collections received in any currency other than the currency in
which any outstanding Obligations are denominated will be accepted and/or


                                       41
<PAGE>   47


applied at the discretion of Agent. At Agent's option, all principal, interest,
fees, costs, expenses and other charges provided for in this Agreement or the
other Financing Agreements may be charged directly to the loan account(s) of any
Borrower. Each Borrower shall make all payments to Agent and Lenders on the
Obligations free and clear of, and without deduction or withholding for or on
account of, any setoff, counterclaim or defense of any kind. If after receipt of
any payment of, or proceeds of Collateral applied to the payment of, any of the
Obligations, Agent or any Lender is required to surrender or return such payment
or proceeds to any Person for any reason, then the Obligations intended to be
satisfied by such payment or proceeds shall be reinstated and continue and this
Agreement shall continue in full force and effect as if such payment or proceeds
had not been received by Agent and such Lender. Each Borrower shall be liable to
pay to Agent and Lenders, and does hereby indemnify and hold Agent or such
Lenders harmless for the amount of any payments or proceeds surrendered or
returned. This Section 6.4 shall remain effective notwithstanding any contrary
action which may be taken by Agent or any Lender in reliance upon such payment
or proceeds. This Section 6.4 shall survive the payment of the Obligations and
the termination or non-renewal of this Agreement.

     6.5 Taxes.

         (a) Any and all payments by or on behalf of any Borrower or any
Guarantor hereunder and under any other Financing Agreement shall be made, in
accordance with Section 6.4, free and clear of and without deduction for any and
all Taxes, excluding (i) income taxes imposed on the net income of any Lender
(or any transferee or assignee of such Lender, including any Participant, any
such transferee or assignee being referred to as a "Transferee") and (ii)
franchise or similar taxes imposed on or determined by reference to the net
income of any Lender (or Transferee), in each case by the United States of
America or by the jurisdiction under the laws of which such Lender (or
Transferee) (A) is organized or any political subdivision thereof or (B) has its
applicable lending office located. In addition, Borrowers agree to pay to the
relevant Governmental Authority in accordance with applicable law any Other
Taxes.

         (b) If any Borrower or Guarantor shall be required by law to deduct or
withhold in respect of any Taxes or Other Taxes from or in respect of any sum
payable hereunder to Agent or any Lender, then:

            (i) the sum payable shall be increased as necessary so that after
making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this Section) such
Lender (or Agent on behalf of such Lender) receives an amount equal to the sum
it would have received had no such deductions or withholdings been made;

            (ii) such Borrower or Guarantor shall make such deductions and
withholdings;

            (iii)such Borrower or Guarantor shall pay the full amount deducted
or withheld to the relevant taxing authority or other authority in accordance
with applicable law; and

            (iv) to the extent not paid to Agent and Lenders pursuant to clause
(i) above, such Borrower or Guarantor shall also pay to Agent or any Lender, at
the time interest is paid, all additional amounts which Agent or any Lender
specifies as necessary to preserve the after-tax yield such Lender would have
received if such Taxes or Other Taxes had not been imposed.


                                       42
<PAGE>   48


         (c) Within thirty (30) days after the date of any payment by any
Borrower or Guarantor of Taxes or Other Taxes, such Borrower or Guarantor shall
furnish to Agent the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment reasonably satisfactory to Agent.

         (d) Borrowers will indemnify Agent and each Lender (or Transferee) for
the full amount of Taxes and Other Taxes paid by Agent or such Lender (or
Transferee, as the case may be). If Agent or such Lender (or Transferee)
receives a refund in respect of any Taxes or Other Taxes for which Lender (or
Transferee) has received payment from any Borrower or Guarantor hereunder, so
long as no Event of Default, or act, condition or event which with notice or
passage of time or both would constitute an Event of Default, shall exist or
have occurred and be continuing, Agent or such Lender (as the case may be) shall
credit to the loan account of Borrowers the amount of such refund plus any
interest received (but only to the extent of indemnity payments made, or
additional amounts paid, by Borrowers or Guarantors under this Section 6.5 with
respect to the Taxes or Other Taxes giving rise to such refund). If a Lender (or
any Transferee) claims a tax credit in respect of any Taxes for which it has
been indemnified by Borrowers or Guarantors pursuant to this Section 6.5, such
Lender will apply the amount of the actual dollar benefit received by such
Lender as a result thereof, as reasonably calculated by Lender and net of all
expenses related thereto, to the Loans. If Taxes or Other Taxes were not
correctly or legally asserted, Agent or such Lender shall, upon PAI's request
and at Borrowers' expense, provide such documents to PAI, in form and substance
satisfactory to Agent, as PAI may reasonably request, to enable Borrowers to
contest such Taxes or Other Taxes pursuant to appropriate proceedings then
available to such Borrower (so long as providing such documents shall not, in
the good faith determination of Agent, have a reasonable likelihood of resulting
in any liability of Agent or any Lender).

         (e) In the event any Transferee is organized under the laws of a
jurisdiction other than the United States, any State thereof or the District of
Columbia (a "Non-U.S. Lender") such Non-U.S. Lender shall deliver to PAI two (2)
copies of either United States Internal Revenue Service Form 1001 or Form 4224,
or, in the case of a Non-U.S. Lender claiming exemption from U.S. Federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of "portfolio interest", a Form W-8, or any subsequent versions thereof
or successors thereto (and, if such Non-U.S. Lender delivers a Form W-8, a
certificate representing that such Non-U.S. Lender is not a bank for purposes of
Section 881(c) of the Code, is not a ten (10%) percent shareholder (within the
meaning of Section 871(h)(3)(B) of the Code) of any Borrower or Guarantor and is
not a controlled foreign corporation related to any Borrower or Guarantor
(within the meaning of Section 864(d)(4) of the Code)), properly completed and
duly executed by such Non-U.S. Lender claiming complete exemption from U.S.
Federal withholding tax on payments by Borrowers or Guarantors under this
Agreement and the other Financing Agreements. Such forms shall be delivered by
any Transferee that is a Non-U.S. Lender on or before the date it becomes a
party to this Agreement (or, in the case of a Transferee that is a Participant,
on or before the date such Participant becomes a Transferee hereunder) and on or
before the date, if any, such Non-U.S. Lender changes its applicable lending
office by designating a different lending office (a "New Lending Office"). In
addition, a Non-U.S. Lender shall upon written notice from PAI promptly deliver
such new forms as are required by the Code or the regulations issued thereunder
to claim exemption from, or reduction in the rate of, U.S. Federal withholding
tax upon the obsolescence or invalidity of any form previously delivered by such
Non-U.S. Lender. Notwithstanding any other provision of this Section 6.5(e), a
Non-U.S. Lender shall not be required to deliver any form pursuant to this
Section 6.5(e) that such Non-U.S. Lender is not legally able to deliver.

         (f) Borrowers and Guarantors shall not be required to indemnify any
Non-U.S. Lender or to pay any additional amounts to any Non-U.S. Lender, in
respect of United States Federal withholding


                                       43

<PAGE>   49
tax pursuant to subsections (a) or (d) above to the extent that the (i) the
obligation to withhold amounts with respect to United States Federal withholding
tax was applicable on the date such Non-U.S. Lender became a party to this
Agreement (or, in the case of a Transferee that is a Participant, on the date
such Participant became a Transferee hereunder) or, with respect to payments to
a New Lending Office, the date such Non-U.S. Lender designated such New Lending
Office with respect to a Loan; provided, that, this subsection (f) shall not
apply (A) to any Transferee or New Lending Office that becomes a Transferee or
New Lending Office as a result of an assignment, participation, transfer or
designation made at the request of Borrowers or Guarantors and (B) to the extent
the indemnity payment or additional amounts any Transferee, acting through a New
Lending Office, would be entitled to receive (without regard to this subsection
(f)) do not exceed the indemnity payment or additional amounts that the person
making the assignment, participation or transfer to such Transferee making the
designation of such New Lending Office, would have been entitled to receive in
the absence of such assignment, participation, transfer or designation or (ii)
the obligation to pay such additional amounts would not have arisen but for a
failure by such Non-U.S. Lender to comply with the provisions of subsection (e)
above.

         6.6 Authorization to Make Loans. Agent and each Lender is authorized to
make the Loans and provide the Letter of Credit Accommodations based upon
telephonic or other instructions received from anyone purporting to be any of
the persons listed on Schedule 6.6 hereto or such other persons as any Borrower
or Guarantor may at any time and from time to time designate in writing to Agent
or any Lender to be authorized to request Loans or Letter of Credit
Accommodations or, at the discretion of Agent or any Lender, if such Loans are
necessary to satisfy any Obligations. All requests for Loans or Letter of Credit
Accommodations hereunder shall specify the date on which the requested advance
is to be made or Letter of Credit Accommodations established (which day shall be
a Business Day and, as to Loans, may be the same day as the date the request for
such Loan is deemed to be received by Agent pursuant to the terms hereof) and
the amount of the requested Loan. Requests received after 11:00 a.m. Dallas time
on any day shall be deemed to have been made as of the opening of business on
the immediately following Business Day. All Loans and Letter of Credit
Accommodations under this Agreement shall be conclusively presumed to have been
made to, and at the request of and for the benefit of, Borrowers when deposited
to the credit of any Borrower (or PAI) or otherwise disbursed or established in
accordance with the instructions of any Borrower (or PAI on its behalf) or in
accordance with the terms and conditions of this Agreement. All Loans and Letter
of Credit Accommodations provided to US Borrowers (or PAI on behalf of such
Borrowers) shall be in or denominated in US Dollars and shall be disbursed only
to bank accounts in the United States of America and all Loans or Letter of
Credit Accommodations provided to Canadian Borrower (or PAI on behalf of
Canadian Borrower) shall be in or denominated in either Canadian Dollars or US
Dollars as Canadian Borrower (or PAI as agent on behalf of Canadian Borrower)
may specify, except as Canadian Lender may other specifically agree in writing
and shall be disbursed only to bank accounts in Canada.

         6.7 Appointment of Agent for Requesting Loans and Receipts of Loans and
Statements.

             (a) Each Borrower hereby irrevocably appoints and constitutes PAI
as its agent to request and receive Loans and Letter of Credit Accommodations
pursuant to this Agreement and the other Financing Agreements from a Lender in
the name or on behalf of such Borrower. Subject to the terms and conditions
contained herein, Lenders may disburse the Loans to such bank account of a
Borrower or PAI or otherwise make such Loans to a Borrower and provide such
Letter of Credit Accommodations to a Borrower as PAI may designate or direct,
without notice to any other Borrower or Obligor.

             (b) PAI hereby accepts the appointment by Borrowers to act as the
agent of Borrowers pursuant to this Section 6.7, PAI shall ensure that the
disbursement of any Loans to each Borrower





                                       44
<PAGE>   50


requested by or paid to PAI or the issuance of any Letter of Credit
Accommodations for a Borrower hereunder shall be paid to or for the account of
such Borrower.

             (c) Each Borrower hereby irrevocably appoints and constitutes PAI
as its agent to receive statements on account and all other notices from Agent
or any Lender with respect to the Obligations or otherwise under or in
connection with this Agreement and the other Financing Agreements.

             (d) No purported termination of the appointment of PAI as agent as
aforesaid shall be effective, except after ten (10) days' prior written notice
to Agent.

         6.8 Use of Proceeds. All Loans made or Letter of Credit Accommodations
provided by or on behalf of a Lender to Borrowers pursuant to the provisions
hereof shall be used by Borrowers only for general operating, working capital
and other proper corporate purposes of Borrowers not otherwise prohibited by the
terms hereof. None of the proceeds will be used, directly or indirectly, for the
purpose of purchasing or carrying any margin security or for the purposes of
reducing or retiring any indebtedness which was originally incurred to purchase
or carry any margin security or for any other purpose which might cause any of
the Loans to be considered a "purpose credit" within the meaning of Regulation U
of the Board of Governors of the Federal Reserve System, as amended.


SECTION 7. COLLATERAL REPORTING AND COVENANTS

         7.1 Collateral Reporting.

             (a) Borrowers shall provide Agent with the following documents in a
form satisfactory to Agent:

                 (i) on a weekly basis or more frequently as Agent may request,
a schedule of sales made, credits issued and cash received, provided, that, (A)
if at any time after March 31, 2000, each of the following conditions is
satisfied, as determined by Agent in good faith, Borrowers shall only be
required to provide Agent with such schedules once each month (in a form and
detail satisfactory to Agent): (1) the Excess Availability for each of the
immediately preceding thirty (30) consecutive days shall have been not less than
$25,000,000, (2) no Loans shall have been outstanding for ten (10) consecutive
days, and (3) no Event of Default or act, condition or event which with notice
or passage shall exist or have occurred and be continuing and (B) in the event
that Borrowers have been providing such reports on a monthly basis, not less
than two (2) Business Days prior to the date of any Loan or Letter of Credit
Accommodation requested by or on behalf of any Borrower, notwithstanding
anything to the contrary contained in clause (i)(A) above, Agent shall have
received such schedules with information as of the last day of the immediately
preceding week;

                 (ii) on a monthly basis or more frequently as Agent may in good
faith request, (A) agings of accounts payable (including the status of payments
to owners and lessors of the leased premises of Borrowers and warehouses and
processors used by Borrowers), (B) agings of accounts receivable (together with
a reconciliation to the previous month's aging and to its general ledger), and
(C) perpetual inventory reports by category and location;

                 (iii) on a monthly basis or more frequently as Agent may in
good faith request, with respect to each category of Inventory, (A) a schedule
specifying the average cost basis and average selling price of such category of
Inventory, and (B) projections of the anticipated average cost basis and






                                       45
<PAGE>   51


average selling price of each category of Inventory for each of the immediately
succeeding three (3) months;

                 (iv) upon Agent's request in good faith, (A) copies of customer
statements and credit memos, remittance advices and reports, and copies of
deposit slips and bank statements, (B) copies of shipping and delivery
documents, (C) copies of purchase orders, invoices and delivery documents for
Inventory and Equipment acquired by Borrowers, and (D) a statement of the
outstanding loans and payments made, and Accounts owing to, Affiliates as of the
last day of the immediately preceding month; and

                 (v) such other reports as to the Collateral as Agent or any
Lender shall reasonably request from time to time.

             (b) If any of Borrower's or Guarantor's records or reports of the
Collateral are prepared or maintained by an accounting service, contractor,
shipper or other agent, each Borrower and Guarantor hereby irrevocably
authorizes such service, contractor, shipper or agent to deliver such records,
reports, and related documents to Agent and to follow Agent's instructions with
respect to further services at any time that an Event of Default exists or has
occurred and is continuing.

         7.2 Accounts Covenants.

             (a) Each Borrower shall notify Agent promptly of: (i) any material
delay in such Borrower's performance of any of its obligations to any Account
Debtor or the assertion of any material claims, offsets, defenses or
counterclaims by any Account Debtor, or any material disputes with Account
Debtors, or any settlement, adjustment or compromise thereof, (ii) all material
adverse information known to any Borrower or Guarantor relating to the financial
condition of any Account Debtor and (iii) any event or circumstance which, to
such Borrower's or Guarantor's knowledge, would be reasonably likely to cause
Agent to consider any then existing Accounts as no longer constituting Eligible
Accounts. No credit, discount, allowance or extension, or agreement with respect
to any credit, discount, allowance or extension, shall be granted by any
Borrower to any Account Debtor without Agent's consent, except in the ordinary
course of such Borrower's business consistent with the practices of such
Borrower as of the date hereof and as to any such agreement so long as Agent
shall have received notice thereof to the extent required under Section 7.1
above. So long as no Event of Default exists or has occurred and is continuing,
each Borrower in its discretion shall have the right to settle, adjust or
compromise any claim, offset, counterclaim or dispute with any Account Debtor.
At any time that an Event of Default exists or has occurred and is continuing,
Agent shall, at its option, have the exclusive right to settle, adjust or
compromise any claim, offset, counterclaim or dispute with Account Debtors or
grant any credits, discounts or allowances.

             (b) Without limiting the obligation of Borrowers to deliver any
other information to Agent, Borrowers shall promptly report to Agent any return
of Inventory by any one Account Debtor if the Inventory so returned in such case
has a value in excess of $100,000. At any time that Inventory is returned,
reclaimed or repossessed, the Account (or portion thereof) which arose from the
sale of such returned, reclaimed or repossessed Inventory shall not be deemed an
Eligible Account. In the event any Account Debtor returns Inventory when an
Event of Default exists or has occurred and is continuing, Borrowers shall, upon
Agent's request, (i) hold the returned Inventory in trust for Lenders, (ii)
segregate all returned Inventory from all of its other property, (iii) dispose
of the returned Inventory solely according to Agent's instructions in good
faith, and (iv) not issue any credits, discounts or allowances with respect
thereto without Agent's prior written consent.




                                       46
<PAGE>   52

             (c) With respect to each Account: (i) the amounts shown on any
invoice or schedule thereof delivered to Agent shall be true and complete (other
than as to de minimis amounts), (ii) no payments shall be made thereon except
payments immediately delivered to Agent pursuant to the terms of this Agreement,
(iii) except as reported to Agent in accordance with the terms hereof, no
credit, discount, allowance or extension or agreement for any of the foregoing
shall be granted to any Account Debtor and except for credits, discounts,
allowances or extensions made or given in the ordinary course of business of
Borrowers consistent with the practices of Borrowers as of the date hereof, (iv)
except as reported to Agent in accordance with the terms hereof, there shall be
no setoff, deductions, contras, defenses, counterclaims or disputes existing or
asserted with respect thereto, (v) none of the transactions giving rise thereto
will violate any applicable Federal, State, Provincial, district, county or
local laws or regulations in any material respect, all documentation relating
thereto will be legally sufficient in all material respects under such laws and
regulations and all such documentation will be legally enforceable in accordance
with its terms.

             (d) Agent shall have the right at any time or times, in Agent's
name or in the name of a nominee of Agent, to verify the validity, amount or any
other matter relating to any Account or other Collateral, by mail, telephone,
facsimile transmission or otherwise.

             (e) Each Borrower shall deliver or cause to be delivered to Agent
or such Lender as Agent may specify, immediately upon such Borrower's receipt
thereof, with appropriate endorsement and assignment, with full recourse to such
Borrower, all chattel paper and instruments constituting Collateral which such
Borrower now owns or may at any time hereafter acquire (i) prior to an Event of
Default, if the aggregate amount of all such chattel paper and instruments
equals or exceeds $250,000 and (ii) after an Event of Default, all such chattel
paper and other instruments regardless of the amount thereof, except as Agent
may otherwise agree.

             (f) Agent may, at any time or times that an Event of Default exists
or has occurred and is continuing, (i) notify any or all Account Debtors or
other obligors in respect thereof that the Accounts have been assigned to a
Lender and that such Lender has a security interest therein and Agent may direct
any or all accounts debtors to make payment of Accounts directly to Agent or
such Lender, (ii) extend the time of payment of, compromise, settle or adjust
for cash, credit, return of merchandise or otherwise, and upon any terms or
conditions, any and all Accounts or other obligations included in the Collateral
and thereby discharge or release the Account Debtor or any other party or
parties in any way liable for payment thereof without affecting any of the
Obligations, (iii) demand, collect or enforce payment of any Accounts or such
other obligations, but without any duty to do so, and Agent and Lenders shall
not be liable for any failure to collect or enforce the payment thereof nor for
the negligence of its agents or attorneys with respect thereto and (iv) take
whatever other action Agent or any Lender may in good faith deem necessary or
desirable for the protection of its or their interests. At any time that an
Event of Default exists or has occurred and is continuing, at Agent's request,
all invoices and statements sent to any Account Debtor or other obligor shall
state that the Accounts and such other obligations have been assigned to such
Lender and are payable directly and only to Agent or such Lender and each
Borrower shall deliver to Agent such originals of documents evidencing the sale
and delivery of goods or the performance of services giving rise to any Accounts
as Agent may require.

         7.3 Inventory Covenants. With respect to the Inventory: (a) each
Borrower shall at all times maintain inventory records reasonably satisfactory
to Agent, keeping in all material respects correct and accurate records
itemizing and describing the kind, type, quality and quantity of Inventory, the
cost therefor and daily withdrawals therefrom and additions thereto; (b) each
Borrower shall conduct a







                                       47
<PAGE>   53


physical count of the Inventory of such Borrower at least once each year, but at
any time or times as Agent may request on or after an Event of Default and for
so long as the same is continuing, and promptly following such physical
inventory shall supply Agent with a report in the form and with such specificity
as may be reasonably satisfactory to Agent concerning such physical count; each
Borrower shall not remove any Inventory from the locations set forth or
permitted herein, without the prior written consent of Agent, except for sales
of Inventory in the ordinary course of such Borrower's business and except to
move Inventory directly from one location of such Borrower set forth or
permitted herein to another such location of such Borrower or any other Borrower
(so long as a financing statement between US Lender, as secured party (as to
assets of US Borrowers) or Canadian Lender, as secured party (as to assets of
Canadian Borrower), and such other Borrower, as debtor, covering such Inventory
has previously been recorded in the appropriate governmental offices of the
jurisdiction of such location); (c) upon Agent's request, Borrowers shall, at
their expense, no more than three (3) times in any twelve (12) month period, but
at any time or times as Agent may request on or after an Event of Default and
for so long as the same is continuing, deliver or cause to be delivered to Agent
written reports or appraisals as to the Inventory in form, scope and methodology
reasonably acceptable to Agent and by an appraiser reasonably acceptable to
Agent, addressed to Agent and Lenders, and upon which Agent and Lenders are
expressly permitted to rely; (d) each Borrower shall produce, use, store and
maintain the Inventory, with all reasonable care and caution and in accordance
with applicable standards of any insurance and in conformity with applicable
laws (including, but not limited to, the requirements of the Federal Fair Labor
Standards Act of 1938, as amended and all rules, regulations and orders related
thereto); (e) each Borrower assumes all responsibility and liability arising
from or relating to the production, use, sale or other disposition of the
Inventory, except for liabilities incurred by a Lender due to acts or omissions
of such Lender which constitute gross negligence or wilful misconduct as
determined pursuant to a final non-appealable order of a court of competent
jurisdiction; (f) each Borrower shall not sell Inventory to any customer on
approval, or any other basis which entitles the customer to return or may
obligate such Borrower to repurchase such Inventory (except for the right of
return of customers for Inventory which is defective or non-conforming); (g)
each Borrower shall keep the Inventory in good and marketable condition (other
than obsolete Inventory); and (h) each Borrower shall not, without prior written
notice to Agent, acquire or accept any Inventory on consignment or approval.

         7.4 Equipment Covenants. With respect to the Equipment: (a) each
Borrower shall keep the Equipment in good order, repair and condition (ordinary
wear and tear and obsolete Equipment excepted) consistent with the practices of
such Borrower as of the date hereof; (b) each Borrower shall use the Equipment
with all reasonable care and caution and in accordance with applicable standards
of any insurance and in conformity with all applicable laws; and (c) each
Borrower shall not remove any Equipment constituting Collateral from the
locations set forth or permitted herein, except to the extent necessary to have
any such Equipment repaired or maintained in the ordinary course of business of
such Borrower or to move Equipment directly from one location of a Borrower set
forth or permitted herein to another such location of such or any other Borrower
(so long as if such Equipment constitutes part of the Collateral, a financing
statement between US Lender, as secured party (as to assets of US Borrowers) or

SECTION 8. REPRESENTATIONS AND WARRANTIES

         Each Borrower and Guarantor hereby jointly and severally represents and
warrants to Agent and each Lender the following (which shall survive the
execution and delivery of this Agreement).

         8.1 Corporate Existence, Power and Authority; Subsidiaries. Each
Borrower and Guarantor is a corporation duly organized and in good standing
under the laws of its state or province of incorporation and is duly qualified
as a foreign or extra-provincial corporation and in good standing in all states,
provinces, or other jurisdictions where the nature and extent of the business
transacted by it or the ownership of assets makes such qualification necessary,
and where the failure to so qualify would have a Material Adverse Effect. The
execution, delivery and performance of this Agreement and the other Financing
Agreements to which it is a party and the transactions contemplated hereunder
and thereunder are all within each Borrower's or Guarantor's corporate powers,
have been duly authorized and are not in contravention of law or the terms of
such Borrower's or Guarantor's certificate of incorporation, by-laws, or other
organizational documentation, or in any material respect of any indenture,
agreement or undertaking to which such Borrower is a party or by which such
Borrower or Guarantor or its property are bound (including, without limitation,
the PCI Senior Secured Note Indenture, the PAI Senior Secured Note Indenture,
the June 1997 Term Loan Agreement, the October 1997 Term Loan Agreement, the
Seller Notes, and the TC Notes). This Agreement and the other Financing
Agreements to which any Borrower or Guarantor is a party constitute legal, valid
and binding obligations of such Borrower or Guarantor enforceable in accordance
with their respective terms except as such enforceability may be limited by (a)
bankruptcy, insolvency, reorganization, moratorium or similar laws of general
applicability affecting the enforcement of creditors' rights and (b) the
application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law). Borrowers and
Guarantors do not have any Subsidiaries except as set forth on the Information
Certificate.

         8.2 Financial Statements; No Material Adverse Change. All financial
statements relating to Borrowers and Guarantors which have been or may hereafter
be delivered by Borrowers or Guarantors to Agent or any Lender have been
prepared in accordance with GAAP (except as to any interim financial statements,
to the extent such statements are subject to normal year-end adjustments and do
not include any notes), and fairly present in all material respects the
financial condition and the results of operation






                                       50
<PAGE>   56


of Borrowers and Guarantors as at the dates and for the periods set forth
therein. Except as disclosed in any interim financial statements furnished by
Borrowers or Guarantors to Agent or any Lender prior to the date of this
Agreement, there has been no material adverse change in the assets, liabilities
and condition, financial or otherwise of Borrowers and Guarantors, since the
date of the most recent audited financial statements furnished by Borrowers or
Guarantors to Agent and Lenders prior to the date of this Agreement.

         8.3 Chief Executive Office; Collateral Locations. Subject to the right
of each Borrower and Guarantor to establish new locations and new chief
executive offices in accordance with Section 9.2 below, the chief executive
office of each Borrower and Guarantor and each Borrower's and Guarantor's
Records concerning Accounts are located only at the addresses set forth in the
Information Certificate and its only other places of business and the only other
locations of Collateral, if any, are the addresses set forth in the Information
Certificate. The Information Certificate correctly identifies any of such
locations which are not owned by Borrowers or Guarantors and sets forth the
owners and/or operators thereof.

         8.4 Priority of Liens; Title to Properties. The hypothecs, security
interests and liens granted to Lenders under this Agreement and the other
Financing Agreements constitute valid and perfected first ranking hypothec and
first priority liens and security interests in and upon the Collateral subject
only to the liens indicated on Schedule 8.4 hereto and the other liens permitted
under Section 9.8 hereof. Each Borrower and Guarantor has good title to all of
its properties and assets subject to no liens, mortgages, pledges, security
interests, hypothecs, prior claims, encumbrances or charges of any kind, except
those granted to Lenders and such others as are specifically listed on Schedule
8.4 hereto or permitted under Section 9.8 hereof.

         8.5 Tax Returns. Each Borrower and Guarantor has filed, or caused to be
filed, in a timely manner all material tax returns, reports and declarations
which are required to be filed by it. All information in such tax returns,
reports and declarations is complete and accurate in all material respects. Each
Borrower and Guarantor has paid or caused to be paid all material taxes due and
payable or claimed due and payable in any assessment received by it, except
taxes the validity of which are being contested in good faith by appropriate
proceedings diligently pursued and available to such Borrower or Guarantor and
with respect to which adequate reserves have been set aside on its books.
Adequate provision has been made for the payment of all material accrued and
unpaid Federal, State, Provincial, county, local, foreign and other taxes of
each Borrower and Guarantor whether or not yet due and payable and whether or
not disputed.

         8.6 Litigation. Except as set forth on the Information Certificate,
there is no present investigation by any Governmental Authority pending, or to
the best of each Borrower's and Guarantor's knowledge threatened, against or
involving any Borrower or Guarantor, or its assets or business and there is no
action, suit, proceeding or claim by any Person pending, or to the best of each
Borrower's and Guarantor's knowledge threatened, against any Borrower or
Guarantor or its assets or goodwill, or against or affecting any transactions
contemplated by this Agreement, which if adversely determined against such
Borrower or Guarantor would reasonably be expected to have a Material Adverse
Effect.

         8.7 Compliance with Other Agreements and Applicable Laws. Each Borrower
and Guarantor is not in default under, or in violation of any of the terms of,
any agreement, indenture, contract, instrument, lease or other commitment to
which it is a party or by which it or any of its assets are bound where such
default or violation would have a Material Adverse Effect. Each Borrower and
Guarantor is in compliance with all applicable provisions of laws, rules,
regulations, licenses, permits, approvals and





                                       51
<PAGE>   57


orders of any foreign, Federal, Provincial, State or local Governmental
Authority where the failure to so comply would have a Material Adverse Effect.

         8.8 Bank Accounts. All of the deposit accounts, investment accounts or
other accounts in the name of or used by any Borrower or Guarantor maintained at
any bank or other financial institution are set forth on Schedule 8.8 hereto,
subject to the right of each Borrower or Guarantor to establish new accounts in
accordance with Section 9.13 below.

         8.9 Environmental Compliance.

             (a) Except as set forth on Schedule 8.9 hereto, each Borrower and
Guarantor does not, and does not permit any Subsidiary to, generate, use, store,
treat, transport, manufacture, handle, produce or dispose of any Hazardous
Materials, on or off its premises (whether or not owned by it) in any manner
which at any time violates any applicable Environmental Law then in effect or
any license, permit, certificate, approval or similar authorization issued to,
or applicable to, such Borrower, Guarantor or Subsidiary thereunder where the
violation has or would reasonably be expected to have a Material Adverse Effect,
and the operations of each Borrower and Guarantor and such Subsidiary comply
with all Environmental Laws as then in effect and all licenses, permits,
certificates, approvals and similar authorizations thereunder where the failure
to so comply would have or would reasonably be expected to have a Material
Adverse Effect.

             (b) Except as set forth on Schedule 8.9 hereto, there is no
investigation or proceeding or written complaint, order, directive, claim,
citation or notice by any Governmental Authority or any other person pending or
to the best of each Borrower's and Guarantor's knowledge threatened, with
respect to any non-compliance with or violation of the requirements of any
Environmental Law by any Borrower or Guarantor where such non-compliance has or
would reasonably be expected to have a Material Adverse Effect or the release,
spill or discharge of any Hazardous Material or the generation, use, storage,
treatment, transportation, manufacture, handling, production or disposal of any
Hazardous Materials or any other environmental, health or safety matter in
violation of any Environmental Law, which is applicable to any Borrower or
Guarantor or its business, operations or assets or any properties at which any
Borrower or Guarantor has transported, stored or disposed of any Hazardous
Materials which has or would reasonably be expected to have a Material Adverse
Effect.

             (c) Except as set forth in Schedule 8.9, no Borrower or Guarantor
has material liability in connection with a release, spill or discharge of any
Hazardous Materials or the generation, use, storage, treatment, transportation,
manufacture, handling, production or disposal of any Hazardous Materials.

             (d) Each Borrower and Guarantor has all licenses, permits,
certificates, approvals or similar authorizations required to be obtained or
filed in connection with the operations of such Borrower or Guarantor under any
Environmental Law and all of such licenses, permits, certificates, approvals or
similar authorizations are valid and in full force and effect where the failure
to have any of the foregoing would have a Material Adverse Effect.

other Borrowers and/or Guarantors, as the case may be, purchase or sell and
supply goods to or from or for the benefit of the others, make loans,

presumed to have been relied on by Agent and Lenders regardless of any
investigation made or information possessed by Agent and Lenders. The
representations and warranties set forth herein shall be cumulative and in
addition to any other representations or warranties which Borrowers or
Guarantors shall now or hereafter give, or cause to be given, to Agent or any

         9.17 Contingent Payment Agreement.

               (a) In connection with the acquisition by Parent of the Capital
Stock of the predecessor of PAI, pursuant to a stock purchase agreement, dated
as of March 24, 1995, the former stockholders of such predecessor (the
"Sellers") agreed to indemnify Parent and its Affiliates for certain
environmental liabilities that result from discharges of hazardous materials, or
violations of Environmental Laws, arising prior to April 20, 1995, from or
relating to certain of the Real Property or arising before or after April 20,
1995 with respect to certain environmental liabilities relating to certain
properties and interests (the "Contingent Payment Properties") held by Parent or
its Affiliates for the benefit of Sellers. Amounts payable pursuant to such
indemnity will generally be payable as follows: (i) out of certain reserves
established on PAI's balance sheet at December 31, 1994, (ii) either by offset
against the amounts payable under the Seller Notes or from amounts held in an
account (the "Contingent Payment Account") established for the deposit of
proceeds from the Contingent Payment Properties, and (iii) in certain
circumstances and subject to specified limitations, out of the personal assets
of the Sellers. Parent will not receive any of the economic benefits from the
Contingent Payment Properties, except that certain environmental and other
indemnification obligations of the Sellers to Parent may be satisfied from
proceeds from such investments and except to the extent that such investments
are owned by Parent on April 20, 2015. As of December 31, 1998, such proceeds,
which are held by Parent in the Contingent Payment Account as collateral for any
indemnification obligations of the Sellers to the Parent, amounted to
approximately $5,700,000.

               (b) Notwithstanding anything to the contrary contained in this
Section 9, Borrowers may sell the Contingent Payment Properties, deposit the
proceeds thereof in the Contingent Payment Account, invest the funds held in the
Contingent Payment Account in investments permitted under the Contingent Payment
Agreement as in effect on the date hereof, make such payments from such
Contingent Payment Account required under the terms of the Contingent Payment
Agreement as in effect on the date hereof, set off against the Seller Notes and
take other actions as are reasonably related to the foregoing, and required
under the terms of, and effected in accordance with the terms of, the Contingent
Payment Agreement as in effect on the date hereof and such action shall not
constitute a breach of the terms hereof, provided, that, notwithstanding the
foregoing, in no event shall any such actions constitute a breach of Sections
9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.8, 9.11, 9.14, 9.15, 9.16, 9.18, 9.19, or 9.20
hereof.

         9.18 Applications under Insolvency Statutes. Each Borrower acknowledges
that its business and financial relationships with Agent and Lenders are unique
from its relationship with any other of its creditors, and agrees that it shall
not file any plan of arrangement under the Companies' Creditors Arrangement Act
(Canada) or make any proposal under the Bankruptcy and Insolvency Act (Canada)
which provides for, or would permit directly or indirectly, Agent or any Lender
to be classified with any other creditor for purposes of such plan or proposal
or otherwise.

         9.19 Year 2000 Compliance. Each Borrower and Guarantor shall take all
action which may be required so that its computer-based information systems,
including, without limitation, all of its proprietary computer hardware and
software (and whether supplied by others or with



                                       77
<PAGE>   83

which Borrowers' or Guarantors' systems interface) are able to operate
effectively and correctly process data using dates on or after January 1, 2000.
Compliance with the foregoing shall mean that the systems will operate and
correctly process data without human intervention such that (a) there is correct
century recognition, (b) calculations properly accommodate same century and
multi-century formulas and date values, and (c) all leap years shall be
calculated correctly. Upon Agent's request after September 30, 1999, Borrowers
and Guarantors shall certify to Agent in writing that its information systems
have been modified, updated and programmed as required by this Section,
provided, that, Borrowers and Guarantors have received any certification from
Agent and Lenders required in order for Borrowers and Guarantors to provide such
certification to Agent. On and after September 30, 1999, Borrowers and
Guarantors the computer-based information systems of Borrowers and Guarantors
shall be, and with ordinary course upgrading and maintenance, will continue to
be sufficient to permit Borrowers and Guarantors to conduct its business without
any adverse effect as a result of the year 2000.

         9.20 Costs and Expenses. Borrowers and Guarantors shall pay to Agent
all reasonable costs, expenses, filing fees and taxes paid or payable in
connection with the preparation, negotiation, execution, delivery, recording,
administration, collection, liquidation, enforcement and defense of the

non-appealable order of a court of competent jurisdiction; (h) all out-of-pocket

agreements, documents and instruments, and do or cause to be done such further
acts as may be necessary or proper to evidence, perfect, maintain and enforce
the hypothecs, security interests and the priority thereof in the Collateral and
to otherwise effectuate the provisions or purposes of this Agreement or any of
the other Financing Agreements. Agent may at any time and from time to time

conditions precedent to the making of Loans and providing Letter of Credit
Accommodations contained herein are satisfied in all material respects. In the
event of such request by Agent, Lenders may, at their option, cease to make any
further Loans or provide any further Letter of Credit Accommodations until Agent
has received such certificate and, in addition, Agent and Lenders have
determined that such conditions are satisfied in all material respects. Where
permitted by law, each Borrower hereby authorizes Agent or Agent's

               (n) there shall be an event of default under any of the other
Financing Agreements.

         10.2 Remedies.

               (a) At any time an Event of Default exists or has occurred and is
continuing, Agent and Lenders shall have all rights and remedies provided in
this Agreement, the other Financing Agreements, the PPSA, the UCC and other
applicable law, all of which rights and remedies may be exercised without notice
to or consent by any Borrower or Obligor, except as such notice or consent is
expressly provided for hereunder or required by applicable law. All rights,
remedies and powers granted to Agent and Lenders hereunder, under any of the
other Financing Agreements, the PPSA, the UCC or other applicable law, are
cumulative, not exclusive and enforceable, in Agent's or any Lender's
discretion, alternatively, successively, or concurrently on any one or more
occasions, and shall include, without limitation, the right to apply to a court
of



                                       81
<PAGE>   87

equity for an injunction to restrain a breach or threatened breach by any
Borrower of this Agreement or any of the other Financing Agreements. Agent or
any Lender may, at any time or times, proceed directly against any Borrower or
Obligor to collect the Obligations without prior recourse to the Collateral.

               (b) Without limiting the foregoing, at any time an Event of
Default exists or has occurred and is continuing, Agent on behalf of Lenders
may, in its discretion and without limitation, (i) accelerate the payment of all
Obligations and demand immediate payment thereof to Agent and Lenders (provided,
that, upon the occurrence of any Event of Default described in Sections 10.1(g)
and 10.1(h), all Obligations shall automatically become immediately due and
payable), (ii) with or without judicial process or the aid or assistance of
others, enter upon any premises on or in which any of the Collateral may be
located and take possession of the Collateral or complete processing,
manufacturing and repair of all or any portion of the Collateral, (iii) require
any Borrower, at Borrowers' expense, to assemble and make available to Agent or
any Lender any part or all of the Collateral at any place and time designated by
Agent, (iv) collect, foreclose, receive, appropriate, setoff and realize upon
any and all Collateral, remove any or all of the Collateral from any premises on
or in which the same may be located for the purpose of effecting the sale,
foreclosure or other disposition thereof or for any other purpose, (v) sell,
lease, transfer, assign, deliver or otherwise dispose of any and all Collateral
(including, without limitation, entering into contracts with respect thereto,
public or private sales at any exchange, broker's board, at any office of Agent
or any Lender or elsewhere) at such prices or terms as Agent may deem
reasonable, for cash, upon credit or for future delivery, with Agent or any
Lender having the right to purchase the whole or any part of the Collateral at
any such public sale, all of the foregoing being free from any right or equity
of redemption of Borrowers, which right or equity of redemption is hereby
expressly waived and released by Borrowers and/or (vi) terminate this Agreement.
If any of the Collateral is sold or leased by Agent or a Lender upon credit
terms or for future delivery, the Obligations shall not be reduced as a result
thereof until payment therefor is finally collected by such Lender. If notice of
disposition of Collateral is required by law, ten (10) days' prior notice by
Agent or any Lender to Borrowers designating the time and place of any public
sale or the time after which any private sale or other intended disposition of
Collateral is to be made, shall be deemed to be reasonable notice thereof and
each Borrower waives any other notice. In the event Agent or any Lender
institutes an action to recover any Collateral or seeks recovery of any
Collateral by way of prejudgment remedy, each Borrower waives the posting of any
bond which might otherwise be required.

               (c) For the purpose of enabling Agent and Lenders to exercise the
rights and remedies hereunder, each Borrower and Guarantor hereby grants to
Agent, to the extent assignable, an irrevocable, non-exclusive license
(exercisable without payment of royalty or other compensation to Borrowers or
Guarantors) to use, assign, license or sublicense any of the trademarks,
service-marks, trade names, business names, trade styles, designs, logos and
other source of business identifiers and other Intellectual Property and General
Intangibles now owned or hereafter acquired by any Borrower or Guarantor,
wherever the same may be located, including in such license reasonable access to
all media in which any of the licensed items may be recorded or stored and to
all computer programs used for the compilation or printout thereof.



                                       82
<PAGE>   88

               (d) Agent and Lenders may apply the cash proceeds of Collateral
actually received by Agent or any Lender from any sale, lease, foreclosure or
other disposition of the Collateral to payment of the Obligations, in whole or
in part and in such order as Agent or such Lender may elect, whether or not then
due. Each Borrower shall remain liable to Agent and Lenders for the payment of
any deficiency with interest at the highest rate provided for herein and all
costs and expenses of collection or enforcement, including reasonable attorneys'
fees and legal expenses.

               (e) Without limiting the foregoing, (i) upon the occurrence of an
Event of Default or an act, condition or event which with notice or passage of
time or both would constitute an Event of Default, and for so long as the same
is continuing, a Lender may, at its option, without notice, cease making Loans
or arranging for Letter of Credit Accommodations or Agent may reduce the lending
formulas or amounts of Loans and Letter of Credit Accommodations available to
Borrowers and/or (ii) upon the occurrence of an Event of Default and for so long
as the same is continuing, a Lender may, at its option, terminate any provision
of this Agreement providing for any future Loans or Letter of Credit
Accommodations to be made by such Lender to Borrowers.

         11.1 Governing Law; Choice of Forum; Service of Process; Jury Trial
Waiver.

               (a) The validity, interpretation and enforcement of this
Agreement and the other Financing Agreements and any dispute arising out of the
relationship between the parties hereto, whether in contract, tort, equity or
otherwise, shall be governed by the internal laws of the State of Texas (without
giving effect to principles of conflicts of law) unless otherwise expressly
provided in a Financing Agreement, as to interpretation, enforcement, validity,
construction, effect, choice of law, and in all other respects, including but
not limited to the legality of the interest rate and other charges, but
excluding the creation and perfection of security interests, hypothecs and liens
which shall be governed and controlled by the laws of the relevant jurisdiction.

               (b) Borrowers, Guarantors, Agent and Lenders irrevocably consent
and submit to the non-exclusive jurisdiction of the District Court of the State
of Texas and the United States District Court for the Northern District of Texas
and waive any objection based on venue or forum non conveniens with respect to
any action instituted therein arising under this Agreement or any of the other
Financing Agreements or in any way connected with or related or incidental to
the dealings of the parties hereto in respect of this Agreement or any of the
other Financing Agreements or the transactions related hereto or thereto, in
each case whether now existing or hereafter arising, and whether in contract,
tort, equity or otherwise, and agree that any dispute with respect to any such
matters shall be heard only in the courts described above (except that Agent or
any Lender shall have the right to bring any action or proceeding against any
Borrower, Guarantor or its property in the courts of any other jurisdiction
which Agent or any Lender



                                       83
<PAGE>   89

deems necessary or appropriate in order to realize on the Collateral or to
otherwise enforce its rights against any Borrower, Guarantor or its property).

               (c) Each Borrower and Guarantor hereby waives personal service of
any and all process upon it and consents that all such service of process may be
made by certified mail (return receipt requested) directed to its address set
forth on the signature pages hereof and service so made shall be deemed to be
completed five (5) days after the same shall have been so deposited in the US
mails, or, at Agent's or any Lender's option, by service upon any Borrower or
Guarantor in any other manner provided under the rules of any such courts.
Within thirty (30) days after such service, such Borrower or Guarantor shall
appear in answer to such process, failing which such Borrower or Guarantor shall
be deemed in default and judgment may be entered by Agent or any Lender against
such Borrower or Guarantor for the amount of the claim and other relief
requested.

               (d) BORROWERS, GUARANTORS, AGENT AND LENDERS EACH HEREBY WAIVES
ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i)
ARISING UNDER THIS AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR (ii) IN
ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES
HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR
THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR
HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE.
BORROWERS, GUARANTORS, AGENT AND LENDERS EACH HEREBY AGREES AND CONSENTS THAT
ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT
TRIAL WITHOUT A JURY AND THAT BORROWERS, GUARANTORS, AGENT OR LENDERS MAY FILE
AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL BY JURY.

               (e) Agent and Lenders shall not have any liability to Borrowers
or Guarantors (whether in tort, contract, equity or otherwise) for losses
suffered by Borrowers or Guarantors in connection with, arising out of, or in
any way related to the transactions or relationships contemplated by this
Agreement, or any act, omission or event occurring in connection herewith,
unless it is determined by a final and non-appealable judgment or court order
binding on Agent or such Lender, that the losses were the result of acts or
omissions constituting gross negligence, willful misconduct or bad faith. In any
such litigation, Agent and Lenders shall be entitled to the benefit of the
rebuttable presumption that it acted in good faith and with the exercise of
ordinary care in the performance by it of the terms of this Agreement.

         11.2 Waiver of Notices. Each Borrower and Guarantor hereby expressly
waives demand, presentment, protest and notice of protest and notice of dishonor
with respect to any and all instruments and commercial paper, included in or
evidencing any of the Obligations or the Collateral, and any and all other
demands and notices, of any kind or nature whatsoever with respect to the
Obligations, the Collateral and this Agreement, except such as are expressly



                                       84
<PAGE>   90

provided for herein. No notice to or demand on any Borrower or Guarantor which
Agent or any Lender may elect to give shall entitle Borrowers to any other or
further notice or demand in the same, similar or other circumstances.

         11.3 Amendments and Waivers. Neither this Agreement nor any provision
hereof shall be amended, modified, waived or discharged orally or by course of
conduct, but only by a written agreement signed by an authorized officer of
Agent, and as to amendments or modifications, as also signed by an authorized
officer of Borrowers and Guarantors. Agent and Lenders shall not, by any act,
delay, omission or otherwise be deemed to have expressly or impliedly waived any
of its rights, powers and/or remedies unless such waiver shall be in writing and
signed by an authorized officer of Agent. Any such waiver shall be enforceable
only to the extent specifically set forth therein. A waiver by Agent or any
Lender of any right, power and/or remedy on any one occasion shall not be
construed as a bar to or waiver of any such right, power and/or remedy which
Agent or such Lender would otherwise have on any future occasion, whether
similar in kind or otherwise.

         11.4 Waiver of Counterclaims. Each Borrower and Guarantor waives all
rights to interpose any claims, deductions, setoffs or counterclaims of any
nature (other than compulsory counterclaims) in any action or proceeding with
respect to this Agreement, the Obligations, the Collateral or any matter arising
therefrom or relating hereto or thereto.

         11.5 Indemnification. Borrowers and Guarantors shall indemnify and hold
Agent, each Lender, and its directors, agents, employees and counsel, harmless
from and against any and all losses, claims, damages, liabilities, costs or
expenses imposed on, incurred by or asserted against any of them in connection
with any litigation, investigation, claim or proceeding commenced or threatened
related to the negotiation, preparation, execution, delivery, enforcement,
performance or administration of this Agreement, any other Financing Agreements,
or any undertaking or proceeding related to any of the transactions contemplated
hereby or any act, omission, event or transaction related or attendant thereto,
including, without limitation, amounts paid in settlement, court costs, and the
reasonable fees and expenses of counsel, except for such losses, claims,
damages, liabilities, costs or expenses resulting from the gross negligence or
wilful misconduct of a Lender, its directors, agents, employees or counsel as
determined pursuant to a final, non-appealable order of a court of competent
jurisdiction. To the extent that the undertaking to indemnify, pay and hold
harmless set forth in this Section may be unenforceable because it violates any
law or public policy, Borrowers and Guarantors shall pay the maximum portion
which it is permitted to pay under applicable law to Agent and Lenders in
satisfaction of indemnified matters under this Section. The foregoing indemnity
shall survive the payment of the Obligations and the termination or non-renewal
of this Agreement.

         11.6 Currency Indemnity. If, for the purposes of obtaining judgment in
any court in any jurisdiction with respect to this Agreement or any of the other
Financing Agreements, it becomes necessary to convert into the currency of such
jurisdiction (the "Judgment Currency") any amount due under this Agreement or
under any of the other Financing Agreements in any currency other than the
Judgment Currency (the "Currency Due"), then conversion shall be made at the
rate of exchange prevailing on the Business Day before the day on which judgment
is



                                       85
<PAGE>   91

given. For this purpose, "rate of exchange" means the rate at which Agent is
able, on the relevant date, to purchase the Currency Due with the Judgment
Currency in accordance with its normal practice. In the event that there is a
change in the rate of exchange prevailing between the Business Day before the
day on which the judgment is given and the date of receipt by Agent of the
amount due, Borrowers will, on the date of receipt by Agent, pay such additional
amounts, if any, or be entitled to receive reimbursement of such amount, if any,
as may be necessary to ensure that the amount received by Agent and Lenders on
such date is the amount in the Judgment Currency which when converted at the
rate of exchange prevailing on the date of receipt by Agent is the amount then
due under this Agreement or such other of the Financing Agreements in the
Currency Due. If the amount of the Currency Due which Agent is able to purchase
is less than the amount of the Currency Due originally due to it, Borrowers
shall indemnify and save Agent and Lenders harmless from and against loss or
damage arising as a result of such deficiency. The indemnity contained herein
shall constitute an obligation separate and independent from the other
obligations contained in this Agreement and the other Financing Agreements,
shall give rise to a separate and independent cause of action, shall apply
irrespective of any indulgence granted by Agent from time to time and shall
continue in full force and effect notwithstanding any judgment or order for a
liquidated sum in respect of an amount due under this Agreement or any of the
other Financing Agreements or under any judgment or order.


SECTION 12. AGENTS

         12.1 Appointment, Powers and Immunities. Each Lender hereby irrevocably
appoints and authorizes Agent to act as its agent hereunder and under the other
Financing Agreements with such powers as are specifically delegated to Agent by
the terms of this Agreement and of the other Financing Agreements, together with
such other powers as are reasonably incidental thereto. Agent (a) shall have no
duties or responsibilities except those expressly set forth in this Agreement
and in the other Financing Agreements, and shall not by reason of this Agreement
or any other Financing Agreement be a trustee or fiduciary for any Lender; (b)
shall not be responsible to Lenders for any recitals, statements,
representations or warranties contained in this Agreement or in any other
Financing Agreement, or in any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Financing Agreement, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Financing Agreement
or any other document referred to or provided for herein or therein or for any
failure by any Borrower or Obligor or any other Person to perform any of its
obligations hereunder or thereunder; and (c) shall not be responsible to Lenders
for any action taken or omitted to be taken by it hereunder or under any other
Financing Agreement or under any other document or instrument referred to or
provided for herein or therein or in connection herewith or therewith, except
for its own gross negligence or willful misconduct as determined by a final
non-appealable judgment of a court of competent jurisdiction. Agent may employ
agents and attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it in good faith.
Agent may deem and treat the payee of any note as the holder thereof for all
purposes hereof unless and until the assignment thereof pursuant to an agreement
(if and to the extent permitted



                                       86
<PAGE>   92

herein) in form and substance satisfactory to Agent shall have been delivered to
and acknowledged by Agent.

         12.2 Reliance by Agent. Agent shall be entitled to rely upon any
certification, notice or other communication (including any thereof by
telephone, telecopy, telex, telegram or cable) believed by it to be genuine and
correct and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by Agent. As to any matters not expressly
provided for by this Agreement or any other Financing Agreements, Agent shall in
all cases be fully protected in acting, or in refraining from acting, hereunder
or thereunder in accordance with instructions given by Canadian Lender as to
matters relating to Canadian Borrower and by US Lender as to matters relating to
US Borrowers and Guarantors and otherwise by both Lenders, and such instructions
of such Lenders and any action taken or failure to act pursuant thereto shall be
binding on all Lenders.

         12.3 Events of Default.

               (a) Agent shall not be deemed to have knowledge or notice of the
occurrence of an Event of Default or other failure of a condition precedent to
the Loans and Letter of Credit Accommodations hereunder, unless and until Agent
has received written notice from a Lender or Borrower specifying such Event of
Default or any unfulfilled condition precedent, and stating that such notice is
a "Notice of Default or Failure of Condition". In the event that Agent receives
such a Notice of Default or Failure of Condition, Agent shall give prompt notice
thereof to Lenders. Agent shall (subject to Section 12.7) take such action with
respect to any such Event of Default or failure of condition precedent as shall
be directed by Canadian Lender as to matters relating to Canadian Borrower and
by US Lender as to matters relating to US Borrowers and Guarantors; provided
that, unless and until Agent shall have received such directions, Agent may (but
shall not be obligated to) take such action, or refrain from taking such action,
with respect to or by reason of such Event of Default or failure of condition
precedent, as it shall deem advisable in the best interest of Lenders.

               (b) Except with the prior written consent of Agent, no Lender may
assert or exercise any enforcement right or remedy in respect of the Loans,
Letter of Credit Accommodations or other Obligations, as against any Borrower or
Obligor or any of the Collateral or other property of any Borrower or Obligor.

         12.4 Rights as a Lender. With respect to Loans made and Letter of
Credit Accommodations issued or caused to be issued by it (and any successor
acting as Agent), so long as the Agent shall be a Lender hereunder, it shall
have the same rights and powers hereunder as any other Lender and may exercise
the same as though it were not acting as Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include Agent in its
individual capacity as Lender hereunder. Congress Financial Corporation
(Southwest) (and any successor acting as Agent) and its Affiliates may (without
having to account therefor to any Lender) lend money to, make investments in and
generally engage in any kind of business with Borrower and Obligors (and any of
their Subsidiaries or Affiliates) as if it were not acting as



                                       87
<PAGE>   93

Agent, and Congress Financial Corporation (Southwest) and its Affiliates may
accept fees and other consideration from any Borrower and any Obligor for
services in connection with this Agreement or otherwise without having to
account for the same to Lenders.

         12.5 Indemnification. Lenders agree to indemnify Agent (to the extent
not reimbursed by Borrowers hereunder and without limiting the Obligations of
Borrowers hereunder) for any and all claims of any kind and nature whatsoever
that may be imposed on, incurred by or asserted against Agent (including by any
Lender) arising out of or by reason of any investigation in or in any way
relating to or arising out of this Agreement or any other Financing Agreement or
any other documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby (including the costs and expenses
that Agent is obligated to pay hereunder) or the enforcement of any of the terms
hereof or thereof or of any such other documents, provided, that, no Lender
shall be liable for any of the foregoing to the extent it arises from the gross
negligence or willful misconduct of the party to be indemnified as determined by
a final non-appealable judgment of a court of competent jurisdiction.

         12.6 Non-Reliance on Agent and Other Lenders. Each Lender agrees that
it has, independently and without reliance on Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis of each Borrower and any Obligors and has made its own
decision to enter into this Agreement and that it will, independently and
without reliance upon Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
analysis and decisions in taking or not taking action under this Agreement or
any of the other Financing Agreements. Agent shall not be required to keep
itself informed as to the performance or observance by any Borrower or Obligor
of any term or provision of this Agreement or any of the other Financing
Agreements or any other document referred to or provided for herein or therein
or to inspect the properties or books of any Borrower or Obligor. Agent will use
reasonable efforts to provide Lenders with any information received by Agent
from any Borrower or Guarantor which is required to be provided to Lenders
hereunder, with a copy of any Notice of Default or Failure of Condition received
by Agent from any Borrower or any Lender and with a copy of any notice of an
Event of Default delivered by Agent to any Borrower; provided, that, Agent shall
not be liable to any Lender for any failure to do so, except to the extent that
such failure is attributable to Agent's own gross negligence or willful
misconduct as determined by a final non-appealable judgment of a court of
competent jurisdiction. Except for notices, reports and other documents
expressly required to be furnished to Lenders by Agent hereunder, Agent shall
not have any duty or responsibility to provide any Lender with any other credit
or other information concerning the affairs, financial condition or business of
any Borrower or Obligor(or any of their affiliates) that may come into the
possession of Agent or any of its Affiliates.

         12.7 Failure to Act. Except for action expressly required of Agent
hereunder and under the other Financing Agreements, Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder unless it
shall receive further assurances to its satisfaction from Lenders of their
indemnification obligations under Section 12.5 hereof against any and all
liability and expense that may be incurred by it by reason of taking or
continuing to take any such action.



                                       88
<PAGE>   94

         12.8 Resignation of Agent. Subject to the appointment and acceptance of
a successor Agent as provided below, Agent may resign at any time by giving
fifteen (15) days notice thereof to Lenders and Borrowers. Upon any such
resignation, Lenders shall have the right to appoint a successor Agent with the
consent of Borrower, which consent shall not be unreasonably withheld,
conditioned or delayed. If no successor Agent shall have been so appointed by
Lenders, and/or so consented to by Borrowers and the appointment accepted by
such successor Agent within fifteen (15) days after the retiring Agent's giving
of notice of resignation, then the retiring Agent may, on behalf of Lenders,
appoint (without the consent of Borrowers or Guarantors) a successor Agent that
shall be a bank, commercial finance company or other financial institution that
shall have an office located in the continental United States of America. Upon
the acceptance of any appointment as Agent hereunder by a successor Agent in
accordance with the terms hereof, such successor Agent shall thereupon succeed
to and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Section 12 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

         12.9 Collateral Matters.

               (a) Except as otherwise expressly provided for in this Agreement,
Agent shall have no obligation whatsoever to any Lender or any other Person to
investigate, confirm or assure that the Collateral exists or is owned by any
Borrower or Obligor or is cared for, protected or insured or has been
encumbered, or that any particular items of Collateral meet the eligibility
criteria applicable in respect of the Loans or Letter of Credit Accommodations
hereunder, or whether any particular Reserves are appropriate, or that the liens
and security interests granted to any Lender herein or pursuant hereto or
otherwise have been properly or sufficiently or lawfully created, perfected,
protected or enforced or are entitled to any particular priority, or to exercise
at all or in any particular manner or under any duty of care, disclosure or
fidelity, or to continue exercising, any of the rights, authorities and powers
granted or available to Agent in this Agreement or in any of the other Financing
Agreements, it being understood and agreed that in respect of the Collateral, or
any act, omission or event related thereto, Agent may act in any manner it may
deem appropriate, in its discretion, given Agent's own interest in the
Collateral as a Lender and that Agent shall have no duty or liability whatsoever
to any other Lender, other than liability for its own gross negligence or
willful misconduct as determined by a final non-appealable judgment of a court
of competent jurisdiction.

               (b) US Lender hereby appoints Canadian Lender as agent for
purposes of perfecting the security interests, liens and hypothecs of US Lender
in the Collateral constituting assets and properties of Canadian Borrower to
secure all Obligations of Canadian Borrower to US Lender arising pursuant to the
guarantee by Canadian Borrower of the Obligations of US Borrowers or Guarantors
to US Lender or otherwise. Canadian Lender hereby appoints US Lender as agent
for purposes of perfecting the security interests and liens of Canadian Lender
in the collateral constituting assets and properties of US Borrowers and
Guarantors to secure all Obligations of US Borrowers and Guarantors to Canadian
Lender arising pursuant to the guarantee by US Borrowers and Guarantors of the
Obligations of Canadian Borrower to



                                       89
<PAGE>   95

Canadian Lender or otherwise. Without limiting the generality of the foregoing,
each Lender hereby appoints Agent and each other as agent for the purpose of
perfecting the security interest of the other Lender in assets which, in
accordance with the UCC or the PPSA can be perfected only by possession. Should
any Lender (other than Agent) obtain possession of any such Collateral, such
Lender shall notify Agent thereof and, promptly upon Agent's request therefor,
shall deliver such Collateral to Agent or in accordance with Agent's
instructions.


SECTION 13. ACKNOWLEDGMENT AND RESTATEMENT

         13.1 Existing Obligations. Each Borrower and Guarantor hereby
acknowledges, confirms and agrees that (a) US Borrowers are indebted to US
Lender (as assignee of Existing Lenders pursuant to the Assignment Agreement)
for loans to PAI under the Existing Agreements as of the close of business on
September 23, 1999 in the aggregate principal amount set forth on Schedule 13.1
hereto, which Indebtedness is hereby assumed, adopted and ratified by US
Borrowers, and (b) Canadian Borrower is indebted to Canadian Lender (as assignee
of Existing Lenders pursuant to the Assignment Agreement) for loans to Canadian
Borrower under the Existing Agreements as of the close of business on September
23, 1999 in the aggregate principal amount set forth on Schedule 13.1 hereto, in
each case as to US Borrowers and Canadian Borrower, together with all interest
accrued and accruing thereon (to the extent applicable), and all fees, costs,
expenses and other charges relating thereto, all of which are unconditionally
owing by Borrowers to Agent and Lenders, without offset, defense or counterclaim
of any kind, nature or description whatsoever; provided, that, Borrowers are not
indebted to Agent and Lenders in connection with the Existing Letters of Credit,
except to the extent of any Letter of Credit Accommodation issued to Bank of
America, N.A. with respect thereto.

         13.2 Acknowledgment of Security Interest. Each Borrower and Guarantor
hereby acknowledges, confirms and agrees that: (a) US Lender, as agent for
itself and Canadian Lender, has and shall continue to have a security interest
in, and lien upon, the Collateral of US Borrowers and Guarantors heretofore
granted to US Lenders (as assignee of the Existing Lenders under the Assignment
Agreement) pursuant to the Existing Agreements, as well as any Collateral
granted hereunder or under the other Financing Agreements or otherwise granted
to or held by US Lender, as agent for itself and Canadian Lender; (b) Canadian

SECTION 14. TERM OF AGREEMENT; MISCELLANEOUS

         14.1 Term.

               (a) This Agreement and the other Financing Agreements shall
become effective as of the date set forth on the first page hereof and shall
continue in full force and effect for a term ending on the date which is the
third (3rd) anniversary of the date hereof (the "Renewal Date"); provided, that,
Borrowers may, at their option, after prior notice to Agent as set forth below
(which notice shall be irrevocable) extend the term of this Agreement for up to
two (2) additional one (1) year periods, provided, that, as to each such
extension, each of the following conditions is satisfied as determined by Agent
in good faith: (i) Agent shall have received prior written notice of the
intention of Borrowers to so extend the term of this Agreement not less than
sixty (60) days prior to the Renewal Date (or the first anniversary thereof, in
the case of an extension for the second one (1) year period), (ii) no Event of
Default or act, condition or event which with notice or passage of time or both
would constitute an Event of Default shall exist or have occurred, and (iii)
Borrower shall pay to Agent (for the account of Lenders) on the Renewal Date (or
the first anniversary thereof, in the case of an extension for the second one
(1) year period), an extension fee equal to one-quarter (1/4%) percent of the
Maximum Credit for each one (1) year extension. Lenders may terminate this
Agreement on the Renewal Date or any anniversary thereof, unless Agent has
received a notice of the intention of Borrowers to extend the term of this
Agreement in accordance with the terms set forth above and subject to the
satisfaction of the conditions to such extension, or if earlier, upon an Event
of Default. Upon the effective date of termination or non-renewal of the
Financing Agreements, Borrowers shall pay to Agent (for the account of Lenders),
in full, all outstanding and unpaid Obligations that are not contingent and
shall furnish cash collateral, if any, to Agent (for the account of Lenders) in
such amounts as Agent determines in good faith are reasonably necessary to
secure Agent and Lenders from loss, cost, damage or expense, including
reasonable attorneys' fees and legal expenses, in connection



                                       92
<PAGE>   98

with any contingent Obligations, including issued and outstanding Letter of
Credit Accommodations and checks or other payments provisionally credited to the
Obligations and/or as to which Agent or any Lender has not yet received final
and indefeasible payment. Such payments in respect of the Obligations and cash
collateral, if any, shall be remitted by wire transfer in US Dollars or Canadian
Dollars, as directed by Agent, to such bank account of a Lender, as Agent or
such Lender may, in its discretion, designate to PAI for such purpose. Interest
shall be due until and including the next Business Day, if the amounts so paid
by Borrowers to the bank account designated by Agent or such Lender are received
in such bank account later than 12:00 noon, Dallas time.

               (b) No termination of this Agreement or the other Financing
Agreements shall relieve or discharge any Borrower or Guarantor of its
respective duties, obligations and covenants under this Agreement or the other
Financing Agreements until all Obligations have been fully and finally
discharged and paid (or for which Agent has received cash collateral as provided
in Section 14.1(a) above, as to contingent Obligations), and each Lender's
continuing security interest in the Collateral and the rights and remedies of
Agent and Lenders hereunder, under the other Financing Agreements and applicable
law, shall remain in effect until all such Obligations have been fully and
finally discharged and paid.

               (c) If for any reason this Agreement is terminated prior to the
Renewal Date of the then current term of this Agreement, in view of the
impracticality and extreme difficulty of ascertaining actual damages and by
mutual agreement of the parties as to a reasonable calculation of each Lender's
lost profits as a result thereof, Borrowers agree to pay to Agent for the
benefit of Lenders, upon the effective date of such termination, an early
termination fee in the amount equal to one (1%) percent of the Maximum Credit.
Such early termination fee shall be presumed to be the amount of damages
sustained by Agent and Lenders as a result of such early termination and
Borrowers agree that it is reasonable under the circumstances currently
existing. In addition, Lenders shall be entitled to fifty (50%) percent of such
early termination fee upon the occurrence of any Event of Default described in
Sections 10.1(g) and 10.1(h) hereof, even if Lenders do not exercise their
rights to terminate this Agreement, but elect, at their option, to provide
financing to any Borrower or permit the use of cash collateral under the United
States Bankruptcy Code, the Bankruptcy and Insolvency Act (Canada), or the
Companies Creditors Arrangement Act (Canada). The early termination fee provided
for in this Section 14.1 shall be deemed included in the Obligations.

         14.2 Interpretative Provisions.

               (a) All terms used herein which are defined in Article 1 or
Article 9 of the UCC shall have the meanings given therein unless otherwise
defined in this Agreement.

               (b) All references to the plural herein shall also mean the
singular and to the singular shall also mean the plural unless the context
otherwise requires.

               (c) All references to any person herein shall include their

               (d) The words "hereof", "herein", "hereunder", "this Agreement"

cured in a manner satisfactory to Agent, if such Event of Default is capable of
being cured as determined by Agent.

currency, shall be determined pursuant to the Currency Exchange Convention.

               (h) Any accounting term used in this Agreement shall have, unless
otherwise specifically provided herein, the meaning customarily given in
accordance with GAAP, and all financial computations hereunder shall be computed
unless otherwise specifically provided herein, in accordance with GAAP as
consistently applied and using the same method for inventory valuation as used
in the preparation of the financial statements of any Borrower or Guarantor most
recently received by Lender prior to the date hereof.

               (i) In the computation of periods of time from a specified date
to a later specified date, the word "from" means "from and including", the words
"to" and "until" each mean "to but excluding" and the word "through" means "to
and including".

               (j) Unless otherwise expressly provided herein, (i) references
herein to any agreement, document or instrument shall be deemed to include all
subsequent amendments, modifications, supplements, extensions, renewals,
restatements or replacements with respect thereto, but only to the extent the
same are not prohibited by the terms hereof or of any other Financing Agreement,
and (ii) references to any statute or regulation are to be construed as
including all statutory and regulatory provisions consolidating, amending,
replacing, recodifying, supplementing or interpreting the statute or regulation.

               (k) The captions and headings of this Agreement are for
convenience of reference only and shall not affect the interpretation of this
Agreement.

               (l) This Agreement and other Financing Agreements may use several
different limitations, tests or measurements to regulate the same or similar
matters. All such limitations, tests and measurements are cumulative and shall
each be performed in accordance with their terms.



                                       94
<PAGE>   100

               (m) This Agreement and the other Financing Agreements are the
result of negotiations among and have been reviewed by counsel to Lender and the
other parties, and are the products of all parties. Accordingly, this Agreement
and the other Financing Agreements shall not be construed against Agent or any
Lender merely because of the involvement of Agent or such Lender in their
preparation.

         14.3 Notices. All notices, requests and demands hereunder shall be in
writing and (a) made to Lender at its address set forth on the signature pages
hereof and to PAI, as agent for Borrowers at its chief executive office set

be invalid or unenforceable, such invalidity or unenforceability shall not
invalidate this Agreement as a whole, but this Agreement shall be construed as
though it did not contain the particular provision held to be invalid or
unenforceable and the rights and obligations of the parties shall be construed
and enforced only to such extent as shall be permitted by applicable law.

         14.5 Successors. This Agreement, the other Financing Agreements and any
other document referred to herein or therein shall be binding upon and inure to
the benefit of and be enforceable by Lender, Borrowers, Guarantors and their
respective successors and assigns, except that Borrowers and Guarantors may not
assign their rights under this Agreement, the other Financing Agreements and any
other document referred to herein or therein without the prior written consent
of Agent. Any Lender may, after notice to any Borrower, assign its rights and
delegate its obligations under this Agreement and the other Financing Agreements
and further may assign, or sell participations in, all or any part of the Loans,
the Letter of Credit Accommodations or any other interest herein to another
financial institution or other person, in which event, the assignee or
Participant shall have, to the extent of such assignment or participation, the
same rights and benefits as it would have if it were the Lender hereunder,
except as otherwise provided by the terms of such assignment or participation.
Notwithstanding anything to the contrary contained herein, so long as no Event
of Default shall exist or have occurred and be continuing, Agent and Lenders
shall use reasonable efforts so that any assignee of Canadian Lender hereunder
shall be a Person that is a resident of Canada under the Income Tax Act (Canada)
or is entitled to complete exemption from Canadian withholding tax imposed on or
with respect to any payments to be made to it pursuant to this Agreement.

         14.6 Good Faith. Where used herein, the term "good faith" means
"honesty in fact in the conduct or transaction concerned." Borrowers and
Guarantors shall have the burden of proving any lack of good faith on the part
of Agent or any Lender alleged by them at any time.

         14.7 Entire Agreement. This Agreement, the other Financing Agreements,
any supplements hereto or thereto, and any instruments or documents delivered or
to be delivered in



                                       95

connection herewith or therewith represents the entire agreement and
understanding concerning the subject matter hereof and thereof between the
parties hereto, and supersede all other prior agreements, understandings,
negotiations and discussions, representations, warranties, commitments,
proposals, offers and contracts concerning the subject matter hereof, whether

FINANCING AGREEMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES, AND THE
SAME MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS
BETWEEN THE PARTIES.

         14.11 Choice of Language. The parties hereto confirm that they have
