   ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

           Pursuant to the Agreement of Purchase and Sale dated April 30, 1997
   between the Registrant and Minnesota Mining and Manufacturing Company ("3M"),
   on August 15, 1997, the Registrant completed the acquisition (the "3M Media
   Acquisition") of all of the issued and outstanding capital stock of National
   Advertising Company, a subsidiary of 3M operating 3M's outdoor advertising
   assets ("3M Media"), for approximately $1 billion in cash. In conjunction
   with the completion of the 3M Media Acquisition, the Registrant sold certain
   of the assets acquired from 3M to (i) The Lamar Corporation ("Lamar"),
   pursuant to an Asset Purchase Agreement dated August 15, 1997 between the
   Registrant and Lamar, for a purchase price of approximately $116 million in
   cash and (ii) another outdoor advertising company for a purchase price of
   approximately $1 million in cash.

           The assets acquired by the Registrant upon the completion of the 3M
   Media Acquisition, after giving effect to the sales of assets described
   above, consisted of approximately 20,800 bulletins and 2,400 poster panels in
   38 states, and approximately 6,700 advertising displays in 690 regional malls
   throughout the United States.

           The Registrant financed the purchase price of the 3M Media
   Acquisition and the fees and expenses associated with the 3M Media
   Acquisition and the acquisition financing through (i) approximately $392.1
   million in net proceeds from the sale of Common Stock in a public offering
   completed on May 28, 1997 (the "Common Stock Offering"); (ii) approximately
   $485.8 million in net proceeds from an offering of 8-7/8% Senior Subordinated
   Notes due 2007 completed on June 23, 1997 (the "Notes Offering"); and (iii)
   borrowings under its senior credit facility which was amended and restated on
   August 15, 1997 to, among other things, provide for up to $400 million of
   revolving credit loans and up to $500 million of term loans under the United
   States portion of the senior credit facility. Pending the completion of the
   3M Media Acquisition, the Company used approximately $579 million of the net
   proceeds of the Common Stock Offering and the Notes Offering to reduce
   indebtedness outstanding under the senior credit facility and invested the
   balance of such net proceeds into short term interest bearing securities.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of
Minnesota Mining and Manufacturing Company
 
     We have audited the accompanying balance sheets of National Advertising
Company (the Company) as of December 31, 1995 and 1996, and the related
statements of income and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements have been prepared on the
basis described in Note 1 and are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of National Advertising Company
as of December, 31, 1995 and 1996 and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

                          NATIONAL ADVERTISING COMPANY
 
                         NOTES TO FINANCIAL STATEMENTS
                                 (IN THOUSANDS)
 
1. BASIS OF PRESENTATION
 
     The accompanying financial statements include certain accounts of National
Advertising ("NADCO" or "the Company"), that are primarily dedicated to the
outdoor media and mall advertising businesses in the United States. The Company
is a wholly-owned subsidiary of Minnesota Mining and Manufacturing Company
("3M"). The accounts of the Company have been adjusted to exclude the effects
and results of the following: (1) the Travel Center Advertising business and (2)
the In-Store Media program utilizing 3M Floorminder's Graphics.
 
     The financial statements present the historical financial position, results
of operations and cash flows of the Company, on the basis described above. Other
than amounts related to the customary time lag in paying monthly charges, the
Company has excluded from the balance sheets assets and liabilities related to
its employees' participation in the 3M pension and other postretirement benefit
plans. Current federal and state income taxes payable have been recorded as a
component of net assets.
 
     NADCO owns and operates advertising display faces in outdoor and other
out-of-home media, selling the advertising space to national, regional and local
advertisers throughout the United States.
 
     The statement of income reflects an allocation of certain costs and
expenses from 3M based on services provided by 3M (see Notes 2, 6 and 8). The
accompanying financial statements may not necessarily be indicative of the
financial position, results of operations or cash flows of the Company in the
future or what the financial position, results of operations or cash flows would
have been had the Company been a separate, independent company during the
periods presented.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
     NADCO's revenues are generated from contracts with advertisers generally
covering periods ranging from one to thirty-six months. NADCO recognizes
revenues ratably over the contract term and defers customer prepayments of
rental fees. Costs incurred for the production of outdoor advertising displays
are recognized in the initial month of the contract or as incurred during the
contract period.
 
PREPAID LAND RENT
 
     Most of NADCO's advertising structures are located on leased land. Land
rents are generally paid in advance for periods ranging from one to twelve
months. Prepaid rents are expensed ratably over the related rental term.
 
INVENTORIES
 
     Inventories consist principally of parts and materials for the construction
and replacement of outdoor and mall advertising signage. Inventories are stated
at the lower of cost of market, cost being determined using the first-in,
first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant, and equipment are stated at cost. Depreciation is recorded
using the straight-line method over estimated useful lives of the assets.
 
     Repairs and maintenance are charged to expense when incurred. Expenditures
for significant improvements are capitalized. Upon sale or retirement of
property, plant and equipment, the cost and accumulated

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
depreciation are eliminated from the accounts, and the related gain or loss is
included in the statement of income.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of. The Company assesses the impairment
of its long-lived assets, including intangibles and property and equipment,
whenever economic events or changes in circumstances indicate that the carrying
amounts of the assets may not be recoverable. Long-lived assets are considered
to be impaired when the sum of the expected future operating cash flows,
undiscounted and without interest charges, is less than the carrying amounts of
the related assets. No adjustment was necessary as a result of the above
adoption.
 
PENSION AND POSTRETIREMENT PLANS
 
     NADCO employees participate in 3M pension and other postretirement plans.
The Company has accounted for its participation in the 3M plans as a
participation in multi-employer plans. Accordingly, the statement of income
includes an allocation from 3M for the costs associated with the NADCO employees
who participate in these plans that is comparable to the Company's required
contribution to the plans for the periods presented. Additionally, no assets and
liabilities have been reflected in the balance sheets related to the overall 3M
pension and other postretirement benefit plans since it is not practicable to
segregate the amounts applicable to the Company.
 
INCOME TAXES
 
     The Company is included in the consolidated income tax returns of 3M. The
Company has no tax-sharing agreement, formal or informal, with 3M. For purposes
of the accompanying financial statements, income taxes are determined on the
"separate return" method. The financial statements reflect the application of
Statement of Financial Accounting Standards No. 109, Accounting for Income
Taxes, for all periods presented. Current federal and state income taxes payable
for the Company's operations are included in Net Assets as 3M pays all income
taxes and receives all income tax refunds on the Company's behalf.
 
     Deferred income taxes are recognized for the future tax consequences of
differences between the bases of assets and liabilities and their
financial-reporting amounts at each year-end based on enacted laws and statutory
tax rates applicable to the periods in which the differences are expected to
affect taxable income. Valuation allowances are established when necessary to
reduce deferred tax assets to the amounts expected to be realized. Income tax
expense is the payable for the period and the change during the period in
deferred tax assets and liabilities.
 
ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

8. TRANSACTIONS WITH RELATED PARTIES
 
     3M provides the Company with various services, including certain corporate
accounting, finance and administration, facility management, human resource and
legal. The cost allocations to the Company for such services were approximately
$9,305, $9,058, and $9,183 for the years ended December 31, 1994, 1995 and 1996,
respectively. The amounts allocated are based on historical or actual usage of
services relative to the usage of the other participating affiliated businesses.
 
     Additionally, 3M allocates charges to the Company for its share of the
annual self-insurance expense, consisting of workers' compensation, auto and
general liability claims. This expense allocation is based upon the ratio of
NADCO claims and loss development to the total amount of 3M claims and loss
development. The self-insurance expense allocated to the Company was $5,284,
$6,240, and $6,432 for the years ended December 31, 1994, 1995 and 1996,
respectively.
 
     The Company also rents its corporate headquarters and is charged for the
use of other 3M facilities. The expense allocated to the Company was $4,537,
$4,281 and $5,227 for the years ended December 31, 1994, 1995 and 1996,
respectively.
 
     Personnel of the Company use certain automobiles owned by 3M. The Company
recognized $956, $930 and $993 in rental expense for 1994, 1995 and 1996,
respectively, related to the use of these assets.
 
     The Company invests its excess cash with 3M in a participation investment
account. Interest income earned was $1,249, $1,962 and $2,073 for the years
ended December 31, 1994, 1995 and 1996.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
9. LITIGATION AND CLAIMS
 
     The Company is a defendant in a 1995 Florida federal court suit, filed by
two former NADCO sales representatives who formed a company to compete with
NADCO. This suit seeks approximately $36 million in damages for lost profits and
punitive damages, allegedly arising out of violations of antitrust laws,
intentional tortious interference with business opportunities and defamation of
business reputation. Trial of this matter is scheduled to begin in April 1997.
The plaintiffs have made settlement demands for amounts significantly less than
the amount sought in the suit. Management believes it has adequate defenses,
however, if liability is found, management is not able, at this time, to
estimate the amount or range of potential loss.
 
     In addition to the above matter, various legal actions and claims are
pending or may be instituted or asserted against the Company in the future,
including those arising out of alleged personal injury, discrimination and
antitrust violations, condemnation matters, permit appeals, property owner
disputes, amortization issues, permit violation questions, lease disputes,
foreclosures and property tax issues. Liabilities have been recorded for these
matters to the extent that it is probable that the Company will be found liable
and the minimum amount of liability is determinable.
 
     Management believes that the ultimate outcome of all pending litigation,
after considering recorded liabilities, would not have a material adverse effect
on the Company's financial position or results of operations.
 
10. PENDING SALE OF THE COMPANY
 
     On April 30, 1997, 3M agreed to sell all of the outstanding common stock of
the Company to Outdoor Systems, Inc. for approximately $1.0 billion cash.
 
11. UNAUDITED NOTE TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
 
BASIS OF PRESENTATION
 
     The accompanying unaudited interim financial statements have been prepared
in accordance with generally accepted accounting principles applicable to
interim financial statements. Accordingly, they do not include all of the
information and notes required by generally accepted accounting principles for
complete financial statements. In the opinion of management, all adjustments and
reclassifications considered necessary for a fair and comparable presentation
have been included and are of a normal recurring nature. Operating results for
the six months ended June 30, 1997, are not necessarily indicative of the
results that may be expected for the year ending December 31, 1997.

      unliquidated, accrued or unaccrued, known or unknown, whenever arising,
      including without limitation those debts, liabilities and obligations
      arising under any law, rule, regulation, Action, threatened Action, order
      or consent decree of any court, any governmental or other regulatory or
      administrative agency or commission or any award of any arbitration
      tribunal, and those arising under any contract, guarantee, commitment or
      undertaking for which (i) National is liable or (ii) Seller is liable,

            (ii) "Action" shall mean any action, suit, arbitration, inquiry,

      other regulatory or administrative agency, body or commission or any
      arbitration tribunal.

            (iii) "Litigation" shall have the meaning as given in Section
      4.6(b) hereof.

            (b) Seller and National shall retain and agree to discharge and
      perform all Liabilities that relate exclusively to the outdoor advertising
      assets of National other than those that relate exclusively to the
      Property or the Apportioned Assets (the "National Outdoor Assets"),
      whether such Liabilities arise or are attributable to events occurring
      before, on or after the Closing Date.

            (c) Buyer shall assume and agrees to discharge all Liabilities that
      relate exclusively to the Property other than the Apportioned Assets,
      whether they arise or are attributable to the events occurring before, on,
      or after the Closing Date. Notwithstanding the foregoing, to the extent
      that Seller has knowledge of any Litigation, Buyer shall assume and become
      liable for: (i) Litigation listed on Schedule 4.6 (i) through (iv) hereto

      Property other than the Apportioned Assets that is not listed on Schedule

            (d) Liabilities that relate exclusively to the Apportioned Assets
      shall be referred to as "Shared Liabilities" or "Shared Liability".

      (i)   To the extent such any Shared Liability is not specifically
            allocated among the parties elsewhere in this Agreement, the Buyer's
            share shall be equal to the Buyer's Percentage (as determined in
            Section 2.2) and Buyer shall assume and agree to discharge such
            portion of the Shared Liability and National and Seller shall be
            liable for the balance.

      (ii)  Notwithstanding the foregoing, to the extent that Seller has
            knowledge of any Litigation relating to the Apportioned Assets, such
            Litigation shall be considered a Shared Liability and Buyer shall
            assume and become liable for (i) Litigation related to the
            Apportioned Assets listed on Schedule 4.6 (i) through (iv) hereto
            and (ii) Litigation as of the date hereof exclusively related to the
            Apportioned Assets as of the date hereof that is not listed on
            Schedule 4.6 (i) through (iv) and of which Buyer has knowledge that
            such Litigation is exclusively related to the Apportioned Assets.

      (iii) For those Liabilities arising after the Closing, the Buyer, Seller
            and National shall each be primarily and solely liable for and
            indemnify the others from any such Liability is caused or is
            proximately caused by them. To the extent the Liability is caused or
            proximately caused by more than one of them, the causing parties
            shall share the Liability in proportion to their culpabilities and
            each shall jointly and severally indemnify the non-causing party for
            any losses incurred with respect to such Liability. If the Liability
            is not caused by any of the parties to this Agreement, the Buyer's
            share of such Liability shall be equal to the Buyer's Percentage.
            National and Seller shall be liable for the balance. The provisions
            of this subparagraph shall apply to all Apportioned Assets only
            while it is an Apportioned Asset.

      (iv)  Notwithstanding anything to the contrary herein, Buyer and Seller
            specifically agree that the amount of Buyer's share of the Shared
            Liabilities arising from events occurring on or before the Closing
            that (A) are unknown by Buyer as of the date hereof or (B) have not
            been disclosed to Buyer as of the date hereof less Buyer's share of
            the net fair market value of marketable and book value of
            nonmarketable Apportioned Assets, shall in no event exceed One
            Million and No/100 ($1,000,000.00) Dollars.

      (v)   The parties acknowledge that various claims and administrative
            matters may arise from time to time in respect of Shared Liabilities
            and that it would be in the best interest of the parties hereto to
            designate responsibility for managing and administering any
            particular Shared Liability to one party, which party shall be the
            party whose portion of the Shared Liability is expected to be the
            greater. All out-of-pocket costs and expenses (including, without
            limitation, reasonable


                                       4
<PAGE>   9
            attorneys' fees and all expenses whatsoever reasonably incurred)
            incurred by or on behalf of the party with such management and
            administrative responsibility shall be shared among the parties in
            the same proportions in which the Shared Liability is shared.

      (vi)  The parties hereto shall be entitled to share in any rights and
            assets (including, without limitation, recoveries, claims, rights of
            subrogation and proceeds of asset sales) that relate to the Shared
            Liabilities in the same proportion as the designated responsibility
            of the parties with respect to the Shared Liabilities.

            (e) Buyer shall pay to Seller at the Closing the amounts shown on
      Schedule 1.2(f). Buyer shall also pay the Buyer's Percentage of the
      accrued payroll to the Closing Date for the Extra Employees (as such term
      is defined in the 3M Agreement) employed at 3M's Bedford Park Ill. office,
      plus the accrued payroll to the Closing Date for the 3M employees hired by
      Buyer. At Closing, Buyer shall pay Seller an estimate of such accrued
      payroll and such amounts shall be adjusted and adjustments paid as soon as
      practicable thereafter. To the extent that Seller receives reimbursement
      from 3M of those certain payments pursuant to Section 9.02(c) of the 3M
      Agreement, Seller shall promptly remit such amounts to Buyer.

            (f) The Liabilities and the Shared Liabilities to be assumed by
      Buyer pursuant to this Section and Sections 11.1 and 11.2 shall be
      referred to herein as the "Assumed Liabilities."

            (g) Buyer and Seller shall sign an assumption agreement included
      within the Bill of Sale, Assignment and Assumption to be executed pursuant
      to Article 3 hereof.

2.    CLOSING AND PAYMENT OF THE PURCHASE PRICE

      2.1 Closing/Closing Date. On the Closing Date, on the terms and
conditions set forth herein, Seller shall cause National to sell and Buyer shall
purchase the Property. The "Closing" is the date on which, the place where, and
the manner in which, the acquisition documents transferring ownership of the
Property are executed by the parties and the Purchase Price (as defined below)
paid, and it will be held at the same location as the closing of the 3M
Agreement immediately following the closing of such Agreement, unless extended
by mutual agreement of the parties or as set forth below (the Closing Date").
Should the pre-transaction waiting period pursuant to the HSR Act (as defined
hereinafter) not have expired or been early terminated prior to the Closing date
as defined immediately above, either party by written notice to the other may
extend the Closing Date to a date not later than five (5) business days after
the expiration or early termination of the HSR waiting period, but in no event
later than October 31, 1997 (the "Termination Date"). The conveyance of the
Tangible Assets and the assignment of the Intangible Assets shall be effective
as of the close of business on the Closing Date. Time is of the essence in this
transaction.


                                       5
<PAGE>   10
      2.2 Purchase Price and Payment. (a) The aggregate purchase price to be
paid by Buyer for the Property shall be the sum of (i) the dollar amount
produced by multiplying $1,050,000,000.00 by that percentage derived from
dividing the 1996 gross revenues less agency commissions attributable to the
Structures by $211,000,000 (the "Buyer's Percentage"), as adjusted pursuant to
Subsection (b) below (the "Cash Purchase Price") plus (ii) the dollar amount of
the Assumed Liabilities as of the Closing. The Cash Purchase Price and the
Assumed Liabilities, are collectively referred to herein as the "Purchase
Price"). Payment of the Cash Purchase Price due on the Closing Date plus an
agreed upon estimate of Assumed Liabilities to be paid by Seller to 3M as set
forth on a closing statement shall be in U.S. dollars and shall be made on the
Closing Date by wire transfer of immediately available funds to the account of
Seller at a bank specified by Seller.

      (b) The Purchase Price may be further adjusted immediately prior to
Closing by agreement of the parties.

      (c) The Purchase Price may be further adjusted subsequent to the Closing
pursuant to this Subsection:

      (i)   With 60 days of the Closing, Buyer shall notify Seller in writing of
            any Structure or Structures listed on Schedule 1.1(i) which were not
            in existence as of the Closing (the "Non-existent Structures"). If
            Buyer does not notify Seller of any Non-existent Structures within
            such 60 days, then there shall be no adjustment to the Purchase
            Price pursuant to this Subsection.

      (ii)  Seller shall have 60 days in which to either accept Buyer's listing
            of the Non-existent Structures or to reply to Buyer in writing,
            listing those Non-existent Structures that it does not agree were
            not in existence at the Closing. Upon replying to Buyer as required
            in the previous sentence, Seller shall immediately pay to Buyer in
            immediately available funds the amount of the Purchase Price
            calculated in Subsection (a) above attributable to the Structures
            that it agrees with Buyer were Non-existent Structures at the
            Closing.

      (iii) If Buyer does not reply within such 60 day time period, Buyer's list
            of the Non-existent Structures shall be deemed accepted by Seller
            and Seller shall immediately pay to Buyer in immediately available
            funds the amount of the Purchase Price calculated in Subsection (a)
            above attributable to the Non-Existent Structures.

      (iv)  If Seller does not agree with Buyer's list of Non-existent
            Structures and so notifies Buyer within the 60 day notice period,
            Buyer and Seller shall resolve their differences pursuant to the
            dispute resolution provisions contained in Article 14 of this
            Agreement.

      (d) The Purchase Price may be further adjusted subsequent to the Closing
pursuant to this Subsection:


                                       6
<PAGE>   11
      (i)   With 60 days of the closing, Buyer shall notify Seller in writing of
            any outdoor advertising structure or structures listed on Schedule
            2.2(d) which were in fact in existence as of the Closing (the
            "Existing Structures"). If Buyer does not notify Seller of any
            Existing Structures within such 60 days, then there shall be no
            adjustment to the purchase price pursuant to this Subsection.

      (ii)  Seller shall have 60 days in which to either accept Buyer's listing
            of the Existing Structures or to reply to Buyer in writing, listing
            those Existing Structures that it does not agree were in existence
            at the Closing. Upon receipt of Seller's notice, Buyer shall pay to
            Seller in immediately available funds the amount of the purchase
            price calculated in Subsection (a) above attributable to the
            Structures that it agrees with Buyer were Existing Structures at the
            Closing and Seller shall transfer title to the Existing Structures
            (which shall be deemed Structure for all purposes hereunder) and
            related Property.

      (iii) If Seller does not reply within such 60 day time period, Buyer's
            list of the Existing Structures shall be deemed accepted by Seller
            and Buyer shall pay to Seller in immediately available funds the
            amount of the Purchase Price calculated in Subsection (a) above
            attributable to the Existing Structures and Seller shall transfer
            title to the Existing Structures, (which shall be deemed Structures
            for all purposes hereunder) and related Property.

      (iv)  If Seller does not agree with Buyer's list of Existing Structures
            and so notifies Buyer within the 60 day notice period, Buyer and
            Seller shall resolve their differences pursuant to the dispute
            resolution provisions contained in Article 14 of this Agreement.


      2.3 Deposit. Buyer agrees that upon the execution of this Agreement Buyer
shall deposit the amount of Five Million and No/100 ($5,000,000.00 ) Dollars
(the "Deposit") with Seller, by wire transfer of immediately available funds to
a separate, interest bearing account of Seller at a bank designated by Seller at
an interest rate of not less than 5.25%. In the event that the Closing occurs,
the Deposit shall be applied to the Purchase Price. In the event that the
Closing does not occur, the Deposit (plus interest at such rate) shall be paid
pursuant to Section 12.3.

      2.4 Allocation of Purchase Price. Buyer and Seller agree that they shall
agree subsequent to the Closing on how the Purchase Price shall be allocated for
state income, property and transfer tax and federal income tax purposes to the
components of the Property purchased and sold hereunder.

      2.5 Execution and Delivery of Documents. At or prior to the Closing, the

<PAGE>   14
jurisdictions where the nature of the property owned or leased by it, or the
nature of the business conducted by it, makes such qualification necessary and

the Property, business, assets, financial condition or results of operations of
the Company or Seller (a "Material Adverse Effect").

<PAGE>   19
business dealings with the Property such that the Property will not be
materially impaired and (ii) use its reasonable efforts to maintain in full

      6.3 Access. From the date hereof and prior to the Closing Date, Seller
shall use its best efforts to provide Buyer with such information as Buyer may
from time to time reasonably request and as Seller may have or have access to

Property and the transactions contemplated by this Agreement and the Ancillary
Documents, and shall provide Buyer and its accountants, counsel, consultants and
other representatives reasonable access, during regular business hours and upon
reasonable notice, to the personnel, properties, books and records of the
Company as Buyer may from time to time reasonably request and as Seller may have

to provide Buyer with any information which, in the sole discretion of Seller,
relates to trade secrets or the disclosure of which would violate any law, rule
or regulation or term of any commitment, or if the provision thereof would, in
the sole discretion of Seller, adversely affect the ability of Seller, the
Company or any of their affiliates to assert attorney-client, attorney work
product or other similar privilege. Any disclosure whatsoever during such
investigation by Buyer shall not constitute an enlargement of or additional
representations or warranties of Seller beyond those specifically set forth in
this Agreement. All such information and access shall be subject to the terms
and conditions of the Confidentiality Agreement by and between Buyer and Seller
dated July 22, 1997.

      6.4 Further Assurances. At any time or from time to time after the

      the Closing that it receives from 3M ("Books and Records") without first
      giving written notice to Seller at least 30 days prior to the proposed
      date of such disposition or destruction;

      covenants contained in this Section 6.6(c); provided, however, that any
      such access or copying shall be had or done in such manner so as not to
      interfere with the normal conduct of Seller's business.

            (d) The foregoing provisions of this Section 6.6 shall be in
      addition to the obligations of Seller under Section 13.2(c)(ii).

Seller, Seller shall cause the Company to sublease to Buyer such portion of its
leasehold sufficient to operate such Structure under such terms and conditions
as are contained in the underlying lease with an equitable allocation of rents.

7.    COVENANTS OF BUYER.

      7.1 Buyer's Knowledge of Business; Representations of Seller Modified by
Buyer's Knowledge. To the knowledge of Buyer, the representations and warranties
of Seller made in this Agreement or in any Ancillary Document entered into on or
prior to the date hereof are true and correct. Buyer hereby agrees that to the
extent any representation or warranty of Seller made herein or in any Ancillary
Document is, to the knowledge of Buyer acquired prior to the date hereof, untrue
or incorrect, (i) Buyer shall have no rights hereunder or thereunder by reason
of such untruth or inaccuracy, and (ii) any such representation or warranty by
Seller shall be deemed to be amended to the extent necessary to render it
consistent with such knowledge of Buyer. In addition, between the date hereof

agrees (without prejudice to any rights which Buyer may have under Sections 9.1,
12.1 and 12.2) that, if the Closing occurs, then to the extent any
representation or warranty of Seller made herein or in any Ancillary Document
entered into at or prior to the


                                       16

prior to the Closing, is untrue or incorrect, (x) Buyer shall have no rights
hereunder or thereunder by reason of such untruth or inaccuracy, and (y) any
such representation or warranty by Seller shall be deemed to be amended to the
extent necessary to render it consistent with such knowledge of Buyer.

      7.2 Assumed Liabilities. Unless otherwise agreed to by the parties, Buyer

within five days after Seller advises Buyer of the amount thereof; provided,
however, that Buyer may dispute any such Assumed Liability with the third party
to whom such Assumed Liability is owed, in good faith, by appropriate
proceedings after written notice to Seller of its intent to do so and receipt of
Seller's written consent thereto (which consent shall not be unreasonably
withheld and shall be deemed given if Seller does not object thereto in writing
within ten days after receipt of Buyer's written notice). The grant to Buyer of
such right to dispute shall not in any way affect the obligation of Buyer,
pursuant to Section 13.2(b) or otherwise, to indemnify Seller and its affiliates
against all liability, loss, damage, claim (including third party claims whether
or not meritorious), cost or expense (including without limitation, reasonable
attorney's fees and disbursements) (collectively "Losses") sustained or incurred

to the Buyer's Percentage times the cost of the liability insurance policy
obtained by Seller pursuant to Section 5.03(c) of the 3M Agreement.

      (b) Seller and/or Company shall insure that Buyer is an additional named
insured under any insurance policy for which Buyer pays or reimburses any party
any part of the premium for such policy pursuant to this Section.

      (c) Buyer and Seller agree that any deductible and/or limit on coverage
under any insurance policy obtained pursuant to this Section shall be equitably
divided between Buyer and Seller.

      (d) It is not the intent of the parties hereto that Buyer should pay a
portion of any insurance premium for any insurance policy covering any claim of
any nature or type against Company, and then be required to pay such claim in
full or in part without the benefit of the insurance for which Buyer paid a
portion of the policy premium. To the extent that the Buyer pays any portion of
any insurance premium for any insurance policy covering any liability, loss, or
expense of 3M, Company or Seller that Buyer has assumed pursuant to Section 1.2
or any other Section of this Agreement, Buyer shall not be required to pay to
Seller any amounts for which coverage under such insurance policy is available.

      7.4 Performance Bonds. Buyer shall deliver to Seller or the appropriate
governmental authority, within 30 days of receipt of copies of the bonds to be
replaced, replacement (or, if the beneficiary thereof will not permit
replacement, back-up) performance bonds, payment bonds, bid bonds, letters of
credit, guarantees and similar instruments, in an aggregate principal amount and

its affiliates will have any liability after the Closing. Buyer shall indemnify
and hold Seller and Company harmless from any Losses as a result of 3M, Seller,
or Company having any performance bonds, payment bonds, bid bonds, letters of
credit, guarantees and similar instruments related to the Property outstanding
after Closing (without regard to any deductible amount hereunder).

its sole expense, shall remove from all advertising displays and vehicles
transferred hereby all imprints containing the Names (as defined in Section 8.2)
or Logos (as defined in Section 8.2); provided, however, that (i) Buyer shall
remove all such imprints within 120 days after the Closing Date with respect to
any such advertising displays containing tobacco advertising, and (ii) Buyer
shall not place any new tobacco advertising on any such advertising displays
without removing all such imprints from such displays.

Closing, Buyer shall, at the request of Seller and at the expense of Seller,
execute, acknowledge and deliver any further assumption agreements, instruments

contemplated hereby and by the Ancillary Documents, and the assumption by Buyer
of the Assumed Liabilities.

      7.8 Books and Records; Personnel. To extent that Buyer takes possession of
any of the Books and Records of Company or Seller related to the Property, then
for a period of seven years:

            (c) Buyer shall make available to Seller upon written request (i)
      copies of any Books and Records, (ii) Buyer's personnel to assist Seller
      in locating and obtaining any Books and Records, and (iii) any of Buyer's

      (d)   in writing by Buyer or Seller, if the Closing shall not have
            occurred on or before the Termination Date, provided, however,
            that the right to terminate this Agreement pursuant to this
            Section 12.1(b) shall not be available to a party if such party's
            failure to perform or observe in any material respect any of its
            covenants or agreements contained in this Agreement shall have
            been the cause of, or resulted in, the failure of the
            consummation of the transactions contemplated hereby to occur on
            or before such date; or

      (e)   in writing by either Buyer or Seller, if there shall have been a
            material breach by the other party of any of its representations,
            warranties, covenants or agreements contained herein and such breach
            results in a failure to satisfy a condition to the terminating
            party's obligation to consummate the transactions provided herein
            which cannot be cured or is not cured prior to the Closing Date.

      12.2 Effect on Obligations. Termination of this Agreement pursuant to this
Article 12 shall terminate all obligations of the parties hereunder, except for

liability to the other party hereto.

      12.3 Termination Fee. In the event that Closing does not occur on or
before Termination Date and Seller has the unilateral right to terminate this
Agreement pursuant to Section 12.1(c), then Buyer agrees to pay Seller,
immediately upon Seller's demand, the sum of $5,000,000.00 (five million and
no/100 dollars) as liquidated damages, in which case Buyer and Seller agree that
payment of such fee shall relieve Buyer from any and all further liability for
its breach hereunder. Notwithstanding anything to the contrary herein, upon
payment of the liquidated damages provided for herein, Buyer shall not have any
further liability or obligation to Seller or Company relating to or arising from
its failure to close or its breach of any provision of this Agreement. The
Deposit shall be applied against any amounts payable to Seller under this
Section 12.3. In addition, if the Deposit is paid to Seller under this Section

Agreement or in any agreement, certificate (including the Certificate of Seller
and the Certificate of Buyer) or other Ancillary Document shall survive the
Closing Date until the first anniversary thereof and shall thereupon expire
together with any right to indemnification for breach thereof (except to the
extent a written notice asserting a claim for breach of any such representation
or warranty, describing the nature of the breach in reasonable detail, shall
have been given prior to such date to the party which made such representation
or warranty, in which case such representation and warranty shall survive, to
the extent of such claim only, until such claim is resolved, whether or not the
amount of the damages or expenses resulting from such breach has been finally
determined at the time the notice is given, if, but only if, (i) in the case of
any claim made by Buyer by reason of a third-party claim, the written notice is
accompanied by a copy of the written notice of the third-party claimant or (ii)
in the case of any claim made by Buyer other than by reason of a third-party
claim, some damages or expense shall have been incurred in good faith at or
prior to the date of such notice; and provided that any notice asserting a claim
for breach of any of the representations and warranties contained in Sections
4.6 and 4.8 (or in the Certificate of Seller insofar as it pertains to Sections
4.6 and 4.8) as to Environmental Matters (an "Environmental Breach") shall not
be effective notice unless accompanied by (x) written notice from the applicable
regulatory authority, or, if there has been a claim made against Buyer by a
third party, the written notice of the third-party claimant, alleging the
existence of the conditions as to which an Environmental Breach is claimed or
(y) a written report from an environmental consulting firm reasonably acceptable
to Seller, the fees and expenses of which firm shall be borne solely by Buyer,
confirming in reasonable detail, the existence of the conditions as to which an
Environmental Breach is claimed). The covenants and agreements contained herein
to be performed or complied with prior to the Closing (and the provisions of the
Certificate of Seller and the Certificate of Buyer pertaining thereto) shall
expire at the Closing. The covenants and agreements contained herein to be
performed or complied with at or after the closing (other than the covenant and
agreement to indemnify against breaches of representations and warranties, which
shall expire as set forth in the first sentence of this Section 13.1, but
including the indemnification obligations contained in Sections 7.2, 7.4, 7.5,
8.1, 8.4(c) and 14.15) shall survive the Closing until the expiration of the
applicable statute of limitations. Accordingly, Buyer agrees (without prejudice
to any rights which Buyer may have under Sections 9.1, 12.1 and 12.2) that, if
the Closing occurs, then to the extent any representation or warranty of Seller
made herein or in any Ancillary Document entered into at or prior to the
Closing, to the knowledge of Buyer acquired from and after the date hereof and
prior to the Closing, is untrue or incorrect, (x) Buyer shall have no rights
hereunder by reason of such untruth or inaccuracy, and (y) any such
representation or warranty by Seller shall be deemed to be amended to the extent
necessary to render it consistent with such knowledge of Buyer.

      13.2 Indemnification. (g) If the Closing shall occur, Seller shall
indemnify Buyer and its affiliates and hold each of them harmless from and
against all Losses which are incurred or suffered by any of them (i) by reason
of the breach of any of the representations or warranties made by Seller herein
or in any Ancillary Document or (ii) by reason of the failure by Seller to
perform or comply with any of the covenants or agreements contained herein or in
any Ancillary Document to be performed or complied with by Seller at or after
the Closing. Any recovery by Buyer and its affiliates for indemnification
pursuant to a breach shall be limited as follows: (l) Buyer and its affiliates
shall not be entitled to any recovery unless a claim for indemnification is made
in accordance with Section 13.1 and paragraph (c)(i) of this Section 13.2 and
within the time period of survival set forth in Section 13.1; (2) Buyer and its
affiliates shall not be entitled 


                                       27
<PAGE>   32
to recover any amount for indemnification claims under clause (i) of this
Section 13.2(a) unless and until the amount which Buyer and its affiliates are
entitled to recover in respect of such claims exceeds, in the aggregate, the
dollar amount equal to the Buyer's Percentage times $10,000,000.00 (the
"Deductible"), in which event (subject to clause (3) below) the entire amount
which Buyer and its affiliates are entitled to recover in respect of such claims
less the Deductible shall be payable; and (3) the maximum amount recoverable by
Buyer and its affiliates for indemnification claims under clause (i) of this
Section 13.2(a) shall in the aggregate be equal to the dollar amount equal to
the Buyer's Percentage times $50,000,000.00.

      (h) If the Closing shall occur, Buyer shall indemnify Seller and its
affiliates and hold each of them harmless from and against all Losses which are
incurred or suffered by any of them (i) by reason of the breach by Buyer of any
of the representations or warranties made by Buyer herein or in any Ancillary
Document, (ii) by reason of the failure by Buyer to perform or comply with any
of the covenants or agreements contained herein or in any Ancillary Document to
be performed or complied with by Buyer at or after the Closing or (iii) by
reason of the ownership by Buyer or any of its affiliates of the Property or the
conduct by Buyer or any of its affiliates of its business after the Closing;
provided, however, that Seller and its affiliates shall not be entitled to any
recovery unless a claim for indemnification is made in accordance with paragraph
(c)(i) of this Section 13.2 and within the time period set forth in Section
13.1.

      (i)(i) In the event that any party shall incur or suffer any Losses in
respect of which indemnification may be sought by such party pursuant to the
provisions of this Section 13.2, the party seeking to be indemnified hereunder
(the "Indemnitee") shall assert a claim for indemnification by written notice (a
"Notice") to the party from whom indemnification is sought (the "Indemnitor")
stating the nature and basis of such claim, and if such claim is with respect to
a third-party claim or a claim relating to an Environmental Matter, accompanied
by the documentation set forth in Section 13.1. In the case of Losses arising by
reason of any third-party claim, the Notice shall be given within 30 days of the
filing or other written assertion of any such claim against the Indemnitee, but
the failure of the Indemnitee to give the Notice within such time period shall
not relieve the Indemnitor of any liability that the Indemnitor may have to the
Indemnitee except to the extent that the Indemnitor is prejudiced thereby.

      (ii) The Indemnitee shall provide to the Indemnitor on request all
information and documentation reasonably necessary to support and verify any
Losses which the Indemnitee believes gives rise to a claim for indemnification
hereunder and shall give the Indemnitor reasonable access to all books, records
and personnel in the possession or under the control of the Indemnitee which
would have bearing on such claim.

      (iii) In the case of third-party claims for which indemnification is
sought, the Indemnitor shall have the option, and with respect to such claims
that represent or are in respect of any of the Liabilities ("Liabilities
Claims") shall have the obligation, (x) to conduct any proceedings or
negotiations in connection therewith, (y) to take all other steps to settle or
defend any such claim (provided that the Indemnitor shall not settle any such
claim without the consent of the Indemnitee (which consent shall not be
unreasonably withheld)) and (z) to employ counsel to contest any such claim or
liability in the name of the Indemnitee or otherwise. In any event, the
Indemnitee shall be entitled to participate at its own expense and by its own
counsel in any proceedings relating to any third-party claim. The Indemnitor
shall, within 45 days of receipt of the Notice, notify the Indemnitee of (or, in
the case of a Liabilities Claim, confirm to the


                                       28
<PAGE>   33
Indemnitee) its intention to assume the defense of such claim. Until the
Indemnitee has received notice of the Indemnitor's election whether to (or, in
the case of a Liabilities Claim, the Indemnitor's confirmation of its intention
to) defend any claim, the Indemnitee shall take reasonable steps to defend (but
may not settle) such claim. Except for Liabilities Claims, as to which this
sentence shall not be applicable, if the Indemnitor shall decline to assume the
defense of such claim, or shall fail to notify the Indemnitee within 45 days
after receipt of the Notice of the Indemnitor's election to defend such claim,
the Indemnitee shall defend against such claim (provided that the Indemnitee
shall not settle such claim without the consent of the Indemnitor, which consent
shall not be unreasonably withheld). The expenses of all proceedings, contests
or lawsuits in respect of any such claims (other than those incurred by the
Indemnitee which are referred to in the second sentence of this subparagraph
(iii)) shall be borne by the Indemnitor but only if the Indemnitor is
responsible pursuant hereto to indemnify the Indemnitee in respect of the
third-party claim and, if applicable, only to the extent required by the second
sentence of Section 13.2(a). Regardless of which party shall assume the defense
of the claim, the parties agree to cooperate fully with one another in
connection therewith. In the case of a claim for indemnification made under
Sections 13.2(a)(i) or 13.2(b)(i), (a) if (and to the extent) the Indemnitor is
responsible pursuant hereto for indemnifying the Indemnitee in respect of the
third-party claim, then within ten days after the occurrence of a final
non-appealable determination with respect to such third-party claim, the
Indemnitor shall pay the Indemnitee, in immediately available funds, the amount
of any Losses (or such portion thereof as the Indemnitor shall be responsible
for pursuant to the provisions hereof, including, without limitation, the second
sentence of Section 13.2(a)), and (b) in the event that any Losses incurred by
the Indemnitee do not involve payment by the Indemnitee of a third-party claim,
then, if (and to the extent) the Indemnitor is responsible pursuant hereto for
indemnifying the Indemnitee against such Losses, the Indemnitor shall within ten
days after agreement on the amount of Losses or the occurrence of a final
non-appealable determination of such amount pay to the Indemnitee, in
immediately available funds, the amount of such Losses (or such portion thereof
as the Indemnitor shall be responsible for pursuant to the provisions hereof,
including, without limitation, the second sentence of Section 13.2(a)).

      (d) The provisions of paragraph (c) of this Section 13.2 shall apply to
all claims for indemnification hereunder.

      (e) The indemnification provided in this Section 13.2 shall be the sole
and exclusive remedy any representation or warranty made by Seller in this
Agreement or in any Ancillary Document. All amounts payable by one party in
indemnification of the other shall be considered an adjustment to the Purchase
Price.

      (f) IN NO EVENT SHALL SELLER BE LIABLE FOR LOSS OF PROFITS OR
CONSEQUENTIAL DAMAGES BY REASON OF A BREACH OF ANY REPRESENTATION OR WARRANTY,
WHETHER ORAL OR WRITTEN, MADE BY SELLER IN THIS AGREEMENT, IN ANY ANCILLARY
DOCUMENT OR OTHERWISE.

      (g) Notwithstanding anything in this Agreement to the contrary, neither
Seller nor any of its affiliates shall be responsible for any liability or
obligation as a result of Buyer's failure to comply with applicable law after
the Closing even if the Outdoor Advertising Business acquired hereby is operated
after the Closing in the manner operated prior to Closing.

      (h) Upon making any payment to an Indemnitee for any indemnification claim
pursuant to this Section 13.2, the Indemnitor shall be subrogated, to the extent
of such payment, to any rights which the Indemnitee may have against any other
parties with respect to the subject matter underlying such indemnification
claim.

      (i) Buyer understands and agrees that the rights accorded it by clause (a)
of this Section 13.2 are its sole and exclusive remedy against Seller or any of
its affiliates with respect to any Environmental Matters whatsoever. Buyer (on
its own behalf and on behalf of its affiliates and the successors and assigns of
any of the foregoing) hereby waives any right to seek contribution or other
recovery from Seller or 3M or any of their affiliates that any of them may now
or in the future ever have under 42 U.S.C. Sections 9607 and 9613(f) of the
Comprehensive Environmental Response, Compensation, and Liability Act (42 U.S.C.
Section 601 et seq.), as amended ("CERCLA"), the Hazardous Material
Transportation Act (49 U.S.C. Section 1801 et seq.), the Clean Water Act (33
U.S.C. Section 1251 et seq.), the Resource Conservation and Recovery Act (42
U.S.C.S.C. Section 7401 et seq.), the Emergency Planning and Community

Health Act (29 U.S.C. Section 651 et seq.) or any other federal, state, local or
foreign law relating to Environmental Matters, the rules and regulations
promulgated under any thereof, and any provisions of common law providing for
any remedy or right of recovery with respect to Environmental Matters, as these
laws, rules, regulations and provisions were in the past or are currently in
effect, or may in the future be enacted or be in effect (collectively,
"Environmental Laws"), with respect to the Liabilities. Buyer (on its own behalf
and on behalf of its affiliates and the successors and assigns of any of the
foregoing) hereby further unconditionally releases Seller and 3M and their
respective affiliates from any and all claims, demands, and causes of action
that any of them may now or in the future ever have against Seller or 3M or any
of their respective affiliates for recovery under CERCLA or under any other
Environmental Laws with respect to the Liabilities.

14.   MISCELLANEOUS.

      14.1 Dispute Resolution; Unaided Negotiations. To resolve any disputes
among the parties, Buyer or Seller must first provide written notice to the
other, specifying in as much detail as possible the source or reason for the
dispute, the amount of claimed damages, if any, and the resolution proposed by
the notifying party. The receiving party shall respond in writing to any such
notice within seven business days after receipt. The responding party may
include in its reply a detailed description of any disputes it would like to
resolve and the proposed resolutions. The first notifying party shall respond
within seven business days. If the dispute is not then resolved, there shall
follow within seven business days of the last written response a meeting between
at least one representative of each party. Each party agrees to have present
such person or persons who are authorized to fully and finally resolve the
dispute. The purpose of this meeting shall be to discuss and negotiate in good
faith the complete resolution of any outstanding dispute. The date and time
shall be mutually agreed (within the stated period), and the location of the
meeting shall be chosen by the party responding to the first notice. Each party
shall bear its own costs (including travel expenses) incident to this
negotiation and meeting.

      14.2 Mediation; Litigation. Should the procedure outlined in Section 14.1
not bring about a resolution of the dispute, then within 30 days following the
meeting of principals, the party first sending the notice shall initiate a
voluntary, nonbinding mediation conducted by a mutually-agreed mediator. Should
the parties for any reason be unable or unwilling to agree upon a mediator, they
shall request J-A-M-S/Endispute in New York, NY, to appoint a capable mediator
for them in accordance with the commercial mediation rules of such organization.
The Parties shall bear equally all costs and expenses (including any attorneys'
fees) of this mediation and endeavor in good faith to resolve their differences.
While this mediation shall be nonbinding in all respects (i.e., any agreement
must be accepted by each party), each party agrees that:

            (a) It shall appear when directed by the mediator, be fully prepared
      to work towards a resolution of the dispute, and participate in good faith
      in the mediation towards a resolution of all disputed issues or concerns;

            (b) The duty to mediate in good faith under this Agreement shall
      be specifically enforceable by the courts of Delaware; and

            (c) Should a court in litigation stemming from the same general
      dispute or disagreement among the parties determine that either did not
      participate in good faith in the mediation process hereunder, then such
      party shall be liable for the other party's attorneys' fees in the
      resulting litigation, up to $100,000.

            (d) In the event that the parties are unable to resolve any
      outstanding disagreement or dispute as provided above, then, as a last
      resort, either party may commence Litigation; provided, however, that it
      must do so in the court (state or federal, provided the court selected has
      subject matter jurisdiction) as agreed pursuant to Section 14.14 hereof.

      14.3 Interpretive Provisions. (a) Whenever used in this Agreement the term
"knowledge" shall mean actual knowledge without the need for independent
investigation of any officer or director of Seller or Buyer listed on Schedule
14.3 hereto. The burden of proving that a party or person had knowledge shall be
on the party asserting such knowledge. "Knowledge" as it relates to 3M shall
have the meaning assigned to such concept in the 3M Agreement.

      (b) The inclusion of any item in this Agreement, the Disclosure Schedule
or the Revised Disclosure Schedule shall not be deemed an acknowledgment that
such item is material or would result in a Material Adverse Effect.

      (c) Buyer and Seller confirm and agree that any judgment, order,
settlement, legislation or regulation which has the effect of restricting
tobacco advertising, in whole or in part, shall not be a "Material Adverse
Effect" for purposes of this Agreement.

      (d) Buyer acknowledges receipt of copies of the 3M Agreement together with
its Disclosure Schedule and Revised Disclosure Schedule, and all matters
disclosed therein are deemed "known" by Buyer hereunder.

      (e) Any of the foregoing provisions of this Agreement notwithstanding, the
Parties agree that the construction and enforcement of any and all of the
provisions of this Agreement shall be based on the following guidelines. Except
as otherwise specifically provided in this Agreement:


                                       31
<PAGE>   36
      (i) The Seller's obligation regarding the transfer of the Property is
      strictly limited to delivering that which National has and can deliver as
      of the Closing on an "as is" and "whereas" basis, no more and no less; and

      (ii)  Seller is not giving Buyer any greater, broader or more enforceable
            representations, warranties, covenants or agreements than it
            receives from 3M under the 3M Agreement other than for those
            provisions that relate only and exclusively to Seller's knowledge,
            its corporate existence, authority and ability to perform and as may
            be required for a sale of assets instead of stock in the context of
            the 3M Agreement.

      14.4 Entire Agreement. This Agreement and all Schedules and attachments
hereto constitute the sole understanding of the parties with respect to the
subject matter hereof. Matters disclosed by Seller to Buyer pursuant to any
Section of this Agreement shall be deemed to be disclosed with respect to all
Sections of this Agreement.

      14.5 Successors and Assigns. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective successors and
assigns of the parties hereto; provided, however, that this Agreement may not be
assigned by Buyer without the prior written consent of Seller, except that Buyer
may, at its election, assign this Agreement in full or in part to any direct or
indirect wholly owned subsidiary so long as (i) the representations and
warranties of Buyer made herein are equally true of such assignee, (ii) such
assignment does not have any adverse consequences to Seller or any of its
affiliates (including, without limitation, any adverse tax consequences or any
adverse effect on the ability of Buyer to consummate (or timely consummate) the
transactions contemplated hereby), and (iii) such assignee shall execute a
counterpart of this Agreement agreeing to be bound by the provisions hereof as
"Buyer", and agreeing to be jointly and severally liable with the assignor and
any other assignee for all of the obligations of the assignor hereunder, but no
such assignment of this Agreement or any of the rights or obligations hereunder
shall relieve Buyer of its obligations under this Agreement; and provided,
further, that Buyer may assign its rights but not its obligations under this
Agreement as collateral security under financing arrangements entered into by
Buyer for the purpose of obtaining the funds required for the Purchase Price.

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

      14.7 Modification and Waiver. No amendment, modification or alteration of
the terms or provisions of this Agreement shall be binding unless the same shall
be in writing and duly executed by the parties hereto, except that any of the
terms or provisions of this Agreement may be waived in writing at any time by
the party which is entitled to the benefits of such waived terms or provisions.
No waiver of any of the provisions of this Agreement shall be deemed to or shall
constitute a waiver of any other provision hereof (whether or not similar). No
delay on the part of any party in exercising any right, power or privilege
hereunder shall operate as a waiver thereof.

      14.8 Broker's Fees. Each of the parties hereto (i) represents and warrants
that it has not taken and will not take any action that would cause the other
party hereto to have any obligation or liability to any person for a finder's or
broker's fee, and (ii) agrees to indemnify the other party hereto for breach of
the foregoing representation and warranty, whether or not the Closing occurs.

      14.9 Expenses. Except as otherwise provided herein, Seller and Buyer shall

limiting the generality of the foregoing, fees and expenses of its own financial
consultants, accountants and counsel.

amount (the "Maximum Borrowing Amount") at any one time outstanding which, when
added to such US Revolving Credit Lender's US Revolving Credit Commitment
Percentage of the then outstanding US L/C Obligations, does not exceed such
Lender's US Revolving Credit Commitment. During the US Revolving Credit
Commitment Period the Company may use the US Revolving Credit Commitments by

Revolving Credit Lender. Each US Revolving Credit Lender is hereby authorized to
record the date, Type and amount of each US Revolving Credit Loan made by such
US Revolving Credit Lender, each continuation thereof, each conversion of all or
a portion thereof to another Type, the date and amount of each payment or
prepayment of principal thereof and, in the case of Eurodollar Loans, the length
of each Interest Period with respect thereto, on the schedule annexed to and
constituting a part of its US Revolving Credit Note, and any such recordation
shall constitute prima facie evidence of the accuracy of the information so
recorded; provided, however, that the failure to make any such recordation shall
not affect the obligations of the Company hereunder or under any US Revolving
Credit Note. Each US Revolving Credit Note shall (x) be dated the Closing Date,

Revolving Credit Commitments exceeding US$500,000,000, provided that the
aggregate amount of the Canadian Revolving Credit Commitments and principal
amount of all Canadian Term Loans outstanding after giving effect thereto may
not exceed C$250,000,000 unless the applicable Canadian Security Documents have
been amended in a manner reasonably satisfactory to the Canadian Administrative
Agent to reflect such greater amount. (For purposes of calculations pursuant to

the US Revolving Credit Lenders and/or Canadian Revolving Credit Lenders to
increase its or their US Revolving Credit Commitments and/or, as the case may
be, Canadian Revolving Credit Commitments by an aggregate amount equal to the
increase so requested by the Company.

agreed upon with the Company. On such date of effectiveness the Borrowers and
the Lenders shall take such actions as shall be necessary or appropriate to
cause the US Revolving Credit Loans and the Canadian Revolving Credit Loans to
be held by the US Revolving Credit Lenders and the Canadian Revolving Credit
Lenders, respectively, ratably in accordance with the respective amounts of
their US Revolving Credit Commitments and Canadian Revolving Credit Commitments,

then outstanding Loans of the affected Class or Classes.

account of the Company at the office of the US Administrative Agent specified in

on the first business day in Toronto following the last day of each March, June,
September and December (for the quarter ending on such last day) and on the
Canadian Revolving Credit Commitment Termination Date or such earlier date as
the Canadian Revolving Credit Commitments shall terminate as provided herein
(for the period since the end of the last period for which payment shall have
been made), commencing on the first of such dates to occur after the Closing
Date.

            (c) The Company agrees to pay to the US Administrative Agent the

            2.8 Termination or Reduction of Revolving Credit Commitments. (a)

termination or reduction shall be permitted if, after giving effect thereto and
to any prepayments of the Revolving Credit Loans made on the effective date
thereof, (i) the aggregate principal amount of the US Revolving Credit Loans
then outstanding, when added to the then outstanding US L/C Obligations, would
exceed the US Revolving Credit Commitments then in effect or (ii) the aggregate
principal amount of the Canadian Revolving Credit Loans then outstanding, when
added to the then outstanding Canadian L/C Obligations, would exceed the
Canadian Revolving Credit Commitments then in effect. Any such reduction shall
be in an amount equal to $2,500,000 or a whole multiple of $100,000 in excess
thereof, in the case of the US Revolving Credit Commitments, or C$2,500,000 or a
whole multiple of C$100,000 in excess thereof, in the case of the Canadian
Revolving Credit Commitments, and shall reduce permanently the US Revolving
Credit Commitments or the Canadian Revolving Credit Commitments, as the case may
be, then in effect.

            (b) The US Revolving Credit Commitments shall automatically be
permanently reduced on December 31 of each year, commencing on December 31,
1999, by the percentage set forth below opposite each such date multiplied by
the greatest aggregate amount of US Revolving Credit Commitments in effect prior
to December 31, 1999:

            December 31, 1999             15%
            December 31, 2000             15%
            December 31, 2001             15%
            December 31, 2002             15%
            December 31, 2003             15%
            June 30, 2004          25%

Each such reduction shall be accompanied by prepayment of the US Revolving
Credit Loans (together with fees and interest accrued thereon to the date of
such prepayment and any additional amounts owing under subsection 4.12) to the
extent, if any, that the US Revolving Credit Loans then outstanding, when added
to the US L/C Obligations then outstanding, exceed the amount of the US
Revolving Credit Commitments as so reduced. If, after giving effect to such
prepayment of the US Revolving Credit Loans, the US L/C Obligations then
outstanding exceed the US Revolving Credit Commitments as so reduced, the
Company shall deposit in a cash collateral account with the US Administrative
Agent an amount equal to the amount by which the US L/C Obligations then
outstanding exceed the US Revolving Credit Commitments as so reduced.

            (c) The Canadian Revolving Credit Commitments shall automatically be
permanently reduced on December 31 of each year, commencing on December 31,
1999, by the percentage set forth below opposite each such date multiplied by
the greatest aggregate amount of Canadian Revolving Credit Commitments in effect
prior to December 31, 1999:

            December 31, 1999             15%
            December 31, 2000             15%
            December 31, 2001             15%
            December 31, 2002             15%
            December 31, 2003             15%
            June 30, 2004          25%

                                                                              35


Each such reduction shall be accompanied by prepayment of the Canadian Revolving
Credit Loans that are C$ Prime Loans (together with fees and interest accrued
thereon to the date of such prepayment and any additional amounts owing under
subsection 4.12) or, in the case of Canadian Revolving Credit Loans that are
Bankers' Acceptances, cash collateralization of such Bankers' Acceptances as set
forth below to the extent, if any, that the Canadian Revolving Credit Loans then
outstanding, when added to the Canadian L/C Obligations then outstanding, exceed
the amount of the Canadian Revolving Credit Commitments as so reduced. If, after
giving effect to such prepayment of the Canadian Revolving Credit Loans that are
C$ Prime Loans, the sum of the aggregate face amount of Canadian Revolving
Credit Loans that are Bankers' Acceptances and the aggregate amount of Canadian
L/C Obligations then outstanding exceed the Canadian Revolving Credit
Commitments as so reduced, the Canadian Borrower shall deposit in a cash
collateral account with the Canadian Administrative Agent an amount equal to the
amount by which such sum exceeds the Canadian Revolving Credit Commitments as so
reduced.

            2.9 US Term Loans. Subject to the terms and conditions hereof, (a)
each US Term Loan Lender severally agrees to continue or, as applicable, to make
a term loan (each, a "US Term Loan", collectively, the "US Term Loans") to the
Company in a principal amount equal to the amount set forth opposite such
Lender's name in Schedule 1.1A under the heading "US Term Loan Commitment" on
the Acquisition Closing Date. The US Term Loans shall be denominated in US$ and
may from time to time be (a) Eurodollar Loans, (b) ABR Loans or (c) a
combination thereof, as determined by the Company and notified to the US
Administrative Agent in accordance with subsection 2.14 and 4.4, as the case may
be.

            2.10 Canadian Term Loans. Subject to the terms and conditions
hereof, each Canadian Term Loan Lender severally agrees to continue or, as
applicable, make term loans to the Canadian Borrower (such loans, the "Canadian
Term Loans") on the Closing Date in the principal amount set forth opposite such
Lender's name in Schedule 1.1A under the heading "Canadian Term Loan
Commitment". The Canadian Term Loans shall be denominated in US$ and may from
time to time be Eurodollar Loans, ABR Loans or a combination thereof, as
determined by the Canadian Borrower and notified to the Canadian Administrative
Agent in accordance subsections 2.14 and 4.4, as the case may be.

            2.11 US Term Notes and Repayment. (a) The Company agrees that, upon
the request to the US Administrative Agent by any US Term Loan Lender made on or
prior to the Closing Date or in connection with any assignment pursuant to
subsection 11.6, to evidence such Lender's US Term Loan the Company will execute
and deliver to such Lender a promissory note substantially in the form of
Exhibit A-2 (each, as amended, supplemented, replaced or otherwise modified from
time to time, a "US Term Note"), with appropriate insertions therein as to
payee, date and principal amount, payable to the order of such US Term Loan
Lender and in a principal amount equal to the amount set forth under such US
Term Loan Lender's name on Schedule 1.1A opposite the heading "US Term Loan
Commitment." Any US Term Note shall (i) be dated the Closing Date, (ii) be
payable as provided in subsection 2.11(b) and (iii) provide for the payment of
interest in accordance with subsection 4.1.

            (b) The US Term Loans shall be payable in consecutive quarterly

            2.14 Procedure for Term Loan Borrowings.

            (a) Closing Date Borrowings. The Canadian Borrower shall give the US
Administrative Agent, irrevocable notice (which notices must be received by the
Canadian Administrative Agents prior to 10:00 A.M., New York City time, (a)
three Business Days prior to the Closing Date, if all or any part of the
Canadian Term Loans are to be initially Eurodollar Loans following the Closing
Date or (b) one Business Day prior to the Closing Date, otherwise) requesting
that the Canadian Term Loan Lenders continue and make Canadian Term Loans on the
Closing Date and specifying (i) whether the Canadian Term Loans following the
Closing Date are to be initially Eurodollar Loans, ABR Loans or a combination
thereof, as applicable, and (ii) if the Canadian Term Loans are to be entirely
or partly Eurodollar Loans following the Closing Date the amount of such Type of
Loan and the lengths of the initial Interest Periods therefor. Upon receipt of
such notice the Administrative Agent shall promptly notify each Canadian Term
Loan Lender thereof. On the Closing Date (i) each Canadian Term Loan Lender
shall make available to the US Administrative Agent at its office specified in
subsection 11.2 an amount in immediately available funds equal to, in the case
of each Canadian Term Loan Lender, its Canadian Term Loan Commitment Percentage
of US$10,200,000 (the "Closing Date Advance"), and (ii) each Canadian Tranche B
Term Loan (as defined in the Existing Credit Agreement) outstanding on the
Closing Date under the Existing Credit Agreement (after giving effect to the
assignments provided for in subsection 6.1(f)) shall be continued as a Canadian
Term Loan of the same amount hereunder ("Original Advance"). The US
Administrative Agent shall on such Date credit the account of the Canadian
Borrower on the books of such office of the US Administrative Agent with the
aggregate of such amounts made available to the US Administrative Agent by the
Canadian Term Loan Lenders.

            (b) Acquisition Closing Date Borrowings. The Company shall give the
US Administrative Agent irrevocable notice (which notice must be received by the
applicable Administrative Agent prior to 10:00 A.M., New York City time, (a)
three Business Days prior to the Acquisition Closing Date, if all or any part of
the US Term Loans to be made on such Date are to be initially Eurodollar Loans
following the Acquisition Closing Date or (b) one Business Day prior to the
Acquisition Closing Date, otherwise) requesting that the US Term Loan Lenders
make US Term Loans on the Acquisition Closing Date and specifying (i) whether
such Term Loans following the Acquisition Closing Date are to be initially
Eurodollar Loans, ABR Loans or a combination thereof, as applicable, and (ii) if
the Term Loans are to be entirely or partly Eurodollar Loans following the
Acquisition Closing Date the amount of such Type of Loan and the length of the
initial Interest Periods therefor. Upon receipt of such notice the
Administrative Agent shall promptly notify each Term Loan Lender thereof. On the
Acquisition Closing Date each US Term Loan Lender shall make available to the US
Administrative Agent at its office specified in subsection 11.2 an amount in
immediately available funds equal to, in the case of each US Term Lender, its US
Term Loan Commitment Percentage of the aggregate amount of the US Term Loans to
be made on the Acquisition Closing Date in accordance with subsection 2.9. The
US Administrative Agent shall on such Date credit the account of the Company on
the books of such office of the US Administrative Agent with the aggregate of
the amounts made available hereunder to the Administrative Agent by the US Term
Loan Lenders.

            2.15 Repayment of Loans. (a) Each Borrower (as specified in the
succeeding sentence) hereby unconditionally and severally promises to pay to the
applicable Administrative Agent for the account of: (i) in the case of each
Borrower, each Revolving Credit Lender, the
<PAGE>   44
                                                                              38


then unpaid principal amount of each Revolving Credit Loan of such Lender made
to such Borrower, on the US Revolving Credit Commitment Termination Date, in the
case of US Revolving Credit Loans, and on the Canadian Revolving Credit
Commitment Termination Date, in the case of Canadian Revolving Credit Loans (or,
in each case, such earlier date on which the Revolving Credit Loans become due
and payable pursuant to Section 9); (ii) each US Term Loan Lender, the amounts
specified in subsection 2.11(b) on the dates specified in subsection 2.11(b) (or
such earlier date on which the US Term Loans become due and payable pursuant to
Section 9); (iii) each Canadian Term Loan Lender, the amounts specified in
subsection 2.12 on the dates specified in subsection 2.12 (or such earlier date
on which the Canadian Term Loans become due and payable pursuant to Section 9).
The amounts described in clause (i) of the preceding sentence shall be payable
by the applicable Borrower; the amounts described in clause (ii) of the
preceding sentence shall be payable by the Company; and the amounts described in
clause (iii) of the preceding sentence shall be payable by the Canadian
Borrower. Each Borrower hereby further agrees to pay interest on the unpaid
principal amount of the Loans made to it from time to time outstanding from the
Closing Date until payment in full thereof at the rates per annum, and on the
dates, set forth in subsection 4.1.

            (b) Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing indebtedness of each Borrower to such Lender
resulting from each Loan of such Lender from time to time, including, without
limitation, the amounts of principal and interest payable and paid to such
Lender from time to time under this Agreement.

            (c) The US Administrative Agent shall maintain the Register pursuant
to subsection 11.6(d), and a subaccount therein for each US$ Lender, in which
shall be recorded (i) the amount of each US Term Loan, Revolving Credit Loan and
Canadian Term Loan made hereunder, the Type thereof and each Interest Period, if
any, applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Company to each US$ Lender
hereunder and (iii) both the amount of any sum received by the US Administrative
Agent hereunder from the Company and each US$ Lender's share thereof.

            (d) The Canadian Administrative Agent shall maintain the Register
pursuant to subsection 11.6(d), and a subaccount therein for each Canadian
Revolving Credit Lender, in which shall be recorded (i) the amount of each
Canadian Revolving Credit Loans made hereunder and whether such Canadian
Revolving Credit Loans is, as applicable, a C$ Prime Loan or a Bankers'
Acceptance, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Canadian Borrower to each Canadian Revolving
Credit Lender hereunder and (iii) both the amount of any sum received by the
Administrative Agent hereunder from the Borrower and each Canadian Revolving
Credit Lender's share thereof.

            (e) The entries made in the Register and the accounts of each Lender
maintained pursuant to subsections 2.15(c) and (d) shall, to the extent
permitted by applicable law, be prima facie evidence of the existence and
amounts of the obligations of each Borrower therein recorded; provided, however,
that the failure of any Lender or either Administrative Agent to maintain the
Register or any such account, or any error therein, shall not in any manner
affect the obligation of either Borrower to repay (with applicable interest) the
Loans made to such Borrower by such Lender in accordance with the terms of this
Agreement.

                                                                              39


            2.16 Bankers' Acceptances. (a) The Canadian Borrower may issue
Bankers' Acceptances denominated in C$, for acceptance and, at the Canadian
Borrower's option, purchase by the Canadian Revolving Credit Lenders, each in
accordance with the provisions of this subsection 2.16.

            (b) Procedures.

            (1) Notice. The Canadian Borrower shall notify the Canadian
      Administrative Agent by irrevocable written notice by 10:00 A.M., Toronto
      time, one Business Day prior to the Borrowing Date in respect of any
      borrowing by way of Bankers' Acceptances.

            (2) Minimum and Maximum Borrowing Amount. Each borrowing by way of
      Bankers' Acceptances shall be in a minimum aggregate face amount of
      C$4,000,000 or a whole multiple of C$100,000 in excess thereof, and no
      borrowing by way of Bankers' Acceptances shall be permitted hereunder
      which is in an amount greater than the then Available Canadian Revolving
      Credit Commitment.

            (3) Face Amounts. The face amount of each Bankers' Acceptance shall
      be C$100,000 or any whole multiple thereof.

            (4) Term. Bankers' Acceptances shall be issued and shall mature on a
      Business Day. Each Bankers' Acceptance shall have a term of 30, 60, 90 or
      180 days (or such shorter or longer term as shall be agreed to by all of
      the Canadian Revolving Credit Lenders), shall mature on or before the
      Canadian Revolving Credit Termination Date and shall be in form and
      substance reasonably satisfactory to each Canadian Revolving Credit
      Lender.

            (5) Bankers' Acceptances in Blank. To facilitate the acceptance of
      Bankers' Acceptances under this Agreement, the Canadian Borrower shall,
      from time to time as required, provide to each Canadian Revolving Credit
      Lender Drafts in form satisfactory to the Canadian Revolving Credit
      Lenders, duly executed and endorsed in blank by the Canadian Borrower in
      quantities sufficient for each Canadian Revolving Credit Lender to fulfill
      its obligations hereunder. Each Canadian Revolving Credit Lender is hereby
      authorized to accept such Drafts endorsed in blank in such face amounts as
      may be determined by such Canadian Revolving Credit Lender in accordance
      with the provisions of this Agreement, provided that the aggregate amount
      thereof is equal to the aggregate amount of Bankers' Acceptances required
      to be accepted by such Canadian Revolving Credit Lender. No Canadian
      Revolving Credit Lender shall be responsible or liable for its failure to
      accept a Bankers' Acceptance if the cause of such failure is, in whole or
      in part, due to the failure of the Canadian Borrower to provide duly
      executed and endorsed Drafts to the Canadian Administrative Agent on a
      timely basis, nor shall any Canadian Revolving Credit Lender be liable for
      any damage, loss or other claim arising by reason of any loss or improper
      use of any such instrument except loss or improper use arising by reason
      of the gross negligence or willful misconduct of such Canadian Revolving
      Credit Lender, its officers, employees, agents or representatives. Each
      Canadian Revolving Credit Lender shall exercise such care in the custody
      and safekeeping of Drafts as it would exercise in the custody and
      safekeeping of similar property owned by it. Each Canadian Revolving
      Credit Lender will, upon the request of the Canadian Borrower,
<PAGE>   46
                                                                              40


      promptly advise the Canadian Borrower of the number and designation, if
      any, of Drafts then held by it for the Canadian Borrower. Each Canadian
      Revolving Credit Lender shall maintain a record with respect to Drafts and
      Bankers' Acceptances (i) received by it from the Canadian Borrower in
      blank hereunder, (ii) voided by it for any reason, (iii) accepted by it
      hereunder, (iv) purchased by it hereunder and (v) cancelled at their
      respective maturities. Each Canadian Revolving Credit Lender further
      agrees to retain such records in the manner and for the statutory periods
      provided in the various Canadian provincial or federal statutes and
      regulations which apply to such Canadian Revolving Credit Lender.

            (6) Execution of Bankers' Acceptances. Drafts of the Canadian
      Borrower to be accepted as Bankers' Acceptances hereunder shall be duly
      executed on behalf of the Canadian Borrower. Notwithstanding that any
      person whose signature appears on any Bankers' Acceptance as a signatory
      for the Canadian Borrower may no longer be an authorized signatory for the
      Canadian Borrower at the date of issuance of a Bankers' Acceptance, such
      signature shall nevertheless be valid and sufficient for all purposes as
      if such authority had remained in force at the time of such issuance, and
      any such Bankers' Acceptance so signed shall be binding on the Canadian
      Borrower.

            (7) Issuance of Bankers' Acceptances. Promptly following receipt of
      a notice of borrowing by way of Bankers' Acceptances, the Canadian
      Administrative Agent shall so advise the Canadian Revolving Credit Lenders
      and shall advise each Canadian Revolving Credit Lender of the face amount
      of each Draft to be accepted by it and the term thereof. The aggregate
      face amount of Draft to be accepted by a Canadian Revolving Credit Lender
      shall be determined by the Canadian Administrative Agent on a pro rata
      basis by reference to the respective Canadian Revolving Credit Commitments
      of the Canadian Revolving Credit Lenders, except that, if the face amount
      of a Bankers' Acceptance, which would otherwise be accepted by a Canadian
      Revolving Credit Lender, would not be C$100,000 or a whole multiple
      thereof, such face amount shall be increased or reduced by the Canadian
      Administrative Agent in its sole and unfettered discretion to the nearest
      whole multiple of C$100,000.

            (8) Acceptance of Bankers' Acceptances. Each Draft to be accepted by
      a Canadian Revolving Credit Lender shall be accepted at such Canadian
      Revolving Credit Lender's Canadian Lending Office.

            (9) Purchase of Bankers' Acceptances. Each Canadian Revolving Credit
      Lender shall be required to purchase (subject to the commercial
      availability of a resale market in the case of Bankers' Acceptances with a
      term of approximately 30, 60, 90 or 180 days, as the case may be) from the
      Canadian Borrower on such Borrowing Date, at the Applicable BA Discount
      Rate, the Bankers' Acceptances accepted by it on such Borrowing Date and
      to provide to the Canadian Administrative Agent the BA Discount Proceeds
      thereof not later than 12:00 Noon, Toronto time, on such Borrowing Date
      for the account of the Canadian Borrower. The Acceptance Fee payable by
      the Canadian Borrower to such Canadian Revolving Credit Lender under
      subsection 2.16(e) in respect of each Bankers' Acceptance accepted and
      purchased by such Canadian Revolving Credit Lender from the Canadian
      Borrower shall be set off against the BA Discount Proceeds payable by such
      Canadian Revolving Credit Lender under this subsection 2.16(b)(9). Not
      later than 2:00 P.M., Toronto time, on such Borrowing Date the Canadian
      Administrative Agent shall
<PAGE>   47
                                                                              41


      make such BA Discount Proceeds available to the Canadian Borrower by
      crediting the account of the Canadian Borrower on the books of the
      Canadian Administrative Office with the aggregate of the amounts made
      available to the Canadian Administrative Agent by the Canadian Revolving
      Credit Lenders and in like funds as received by the Canadian
      Administrative Agent.

            (10) Sale of Bankers' Acceptances. Each Canadian Revolving Credit
      Lender may at any time and from time to time hold, sell, rediscount or
      otherwise dispose of any or all Bankers' Acceptances accepted and
      purchased by it.

            (11) Waiver of Presentment and Other Conditions. To the extent
      permitted by applicable law, the Canadian Borrower waives presentment for
      payment and any other defense to payment of any amounts due to a Canadian
      Revolving Credit Lender in respect of a Bankers' Acceptance accepted by it
      pursuant to this Agreement which might exist solely by reason of such
      Bankers' Acceptance being held, at the maturity thereof, by such Canadian
      Revolving Credit Lender in its own right, and the Canadian Borrower agrees
      not to claim any days of grace if such Canadian Revolving Credit Lender as
      holder sues the Canadian Borrower on the Bankers' Acceptances for payment
      of the amount payable by the Canadian Borrower thereunder.

            (c) The Canadian Borrower shall reimburse the Canadian Revolving
Credit Lender for, and there shall become due and payable at 10:00 a.m., Toronto
time, on the maturity date for each Bankers' Acceptance, an amount in Canadian
Dollars in same day funds equal to the face amount of such Bankers' Acceptance.
The Canadian Borrower shall make each such reimbursement payment (i) by causing
any proceeds of Refunding Bankers' Acceptances issued in accordance with
subsection 2.16(d) or conversion of such Bankers' Acceptance effected in
accordance with subsection 4.4(c) to be applied in reduction of such
reimbursement payment; and (ii) by depositing the amount of such reimbursement
payment (or any portion thereof remaining unpaid after any application referred
to in clause (i)) to the relevant payment account. The Canadian Borrower's
payment in accordance with this subsection shall satisfy its obligations under
any Bankers' Acceptance to which it relates, and the Canadian Revolving Credit
Lender which has accepted such Bankers' Acceptance shall thereafter be solely
responsible for the payment of such Bankers' Acceptance.

            (d) The Canadian Borrower shall give irrevocable written notice (or
such other method of notification as may be agreed upon between the Canadian
Administrative Agent and the Canadian Borrower) to the Canadian Administrative
Agent at or before 10:00 A.M., Toronto time, one Business Day prior to the
maturity date of each Bankers' Acceptance followed by written confirmation
electronically transmitted to the Canadian Administrative Agent on the same day,
of the Canadian Borrower's intention to issue a Bankers' Acceptance on such
maturity date (a "Refunding Bankers' Acceptance") to provide for the payment of
such maturing Bankers' Acceptance (it being understood that payments by the
Canadian Borrower and fundings by the Canadian Revolving Credit Lenders in
respect of each maturing Bankers' Acceptance and the related Refunding Bankers'
Acceptance shall be made on a net basis reflecting the difference between the
face amount of such maturing Bankers' Acceptance and the BA Discount Proceeds
(net of the applicable Acceptance Fee) of such Refunding Bankers' Acceptance).
If the Canadian Borrower fails to give such notice or does not deposit the
amount of reimbursement payment in accordance with subsection 2.16(c)(ii), the
Canadian Borrower shall be deemed to have

                                                                              42


requested that such maturing Bankers' Acceptances be repaid with the proceeds of
C$ Prime Loans (without any requirement to give notice with respect thereto),
commencing on the maturity date of such maturing Bankers' Acceptances.

            (e) An Acceptance Fee shall be payable by the Canadian Borrower to
each Canadian Revolving Credit Lender in advance (in the manner specified in
subsection 2.16(b)(9)) upon the issuance of a Bankers' Acceptance to be accepted
by such Canadian Revolving Credit Lender calculated at the rate per annum equal
to the Applicable Margin, such Acceptance Fee to be calculated on the face
amount of such Bankers' Acceptance and to be computed on the basis of the number
of days in the term of such Bankers' Acceptance.

            (f) Upon the occurrence of any Event of Default which is continuing,
and in addition to any other rights or remedies of any Canadian Revolving Credit
Lender and the Canadian Administrative Agent hereunder, any Canadian Revolving
Credit Lender or the Canadian Administrative Agent (or such alternate
arrangement as may be agreed upon by the Canadian Borrower and such Canadian
Revolving Credit Lender or the Canadian Administrative Agent, as applicable)
shall be entitled to deposit and retain in an account to be maintained by the
Canadian Administrative Agent (bearing interest at the Canadian Administrative
Agent's rates as may be applicable in respect of other deposits of similar
amounts for similar terms), for the ratable benefit of the Canadian Revolving
Credit Lenders, amounts which are received by such Canadian Revolving Credit
Lender or the Canadian Administrative Agent from the Canadian Borrower hereunder
or as proceeds of the exercise of any rights or remedies of any Canadian
Revolving Credit Lender or the Canadian Administrative Agent hereunder against
the Canadian Borrower, to the extent such amounts may be required to satisfy any
contingent or unmatured obligations or liabilities of the Canadian Borrower to
the Canadian Revolving Credit Lenders or the Canadian Administrative Agent, or
any of them hereunder.

            2.17 Circumstances Making Bankers' Acceptances Unavailable. (a) If
the Canadian Administrative Agent determines in good faith, which determination
shall be final, conclusive and binding upon the Canadian Borrower absent
manifest error, and notifies the Canadian Borrower that, by reason of
circumstances affecting the money market, there is no market for Bankers'
Acceptances, then

            (i) the right of the Canadian Borrower to request a borrowing by way
      of Bankers' Acceptance shall be suspended until the Canadian
      Administrative Agent determines that the circumstances causing such
      suspension no longer exist and the Canadian Administrative Agent so
      notifies the Canadian Borrower; and

            (ii) any notice relating to a borrowing by way of Bankers'
      Acceptance which is outstanding at such time shall be deemed to be a
      notice requesting a borrowing by way of C$ Prime Loan (all as if it were a
      notice given pursuant to subsection 2.6).

            (b) The Canadian Administrative Agent shall promptly notify the
Canadian Borrower and the Canadian Revolving Credit Lenders of the suspension of
the Canadian Borrower's right to request a borrowing by way of Bankers'
Acceptance and of the termination of such suspension.

                          SECTION 3. LETTERS OF CREDIT

            3.1 L/C Commitments. (a) Subject to the terms and conditions hereof,
the US Issuing Lender, in reliance on the agreements of the other US$ Revolving
Credit Lenders set forth in subsection 3.4(a), agrees to issue letters of credit
("US Letters of Credit") for the account of the Company on any Business Day
during the US Revolving Credit Commitment Period in such form as may be approved
from time to time by the US Issuing Lender; provided that the US Issuing Lender
shall have no obligation to issue any US Letter of Credit if, after giving
effect to such issuance, (i) the US L/C Obligations would exceed the US L/C
Commitment or (ii) the Available US Revolving Credit Commitment would be less
than zero. On the Closing Date all US Letters of Credit (as defined in the
Existing Credit Agreement) then outstanding on such date under the Existing
Credit Agreement shall automatically be deemed to be US Letters of Credit
hereunder.

            (b) Subject to the terms and conditions hereof, the Canadian Issuing
Lender, in reliance on the agreements of the other Canadian Revolving Credit
Lenders set forth in subsection 3.4(b), agrees to issue letters of credit
("Canadian Letters of Credit"; together with the US Letters of Credit, the
"Letters of Credit") for the account of the Canadian Borrower on any Business
Day during the Canadian Revolving Credit Commitment Period in such form as may
be approved from time to time by the Canadian Issuing Lender; provided that the
Canadian Issuing Lender shall have no obligation to issue any Canadian Letter of
Credit if, after giving effect to such issuance, (i) the Canadian L/C
Obligations would exceed the Canadian L/C Commitment or (ii) the Available
Canadian Revolving Credit Commitment would be less than zero. On the Closing
Date all Canadian Letters of Credit (as defined in the Existing Credit
Agreement) then outstanding on such date under the Existing Credit Agreement
shall automatically be deemed to be Canadian Letters of Credit hereunder.

            (c) Each Letter of Credit shall (i) in the case of the Company, be
denominated in US Dollars and shall be a stand-by letter of credit issued to
finance the working capital and business needs of the Company and its Restricted
Subsidiaries (if any) in the ordinary course of business, and, in the case of
the Canadian Borrower, be denominated in C$ and shall be a stand-by letter of
credit issued to finance the working capital and business needs of the Canadian
Borrower and its Restricted Subsidiaries in the ordinary course of business and
(ii) expire no later than the earlier of (x) the one year anniversary of its
issuance and (y) the US Revolving Credit Commitment Termination Date, in the
case of US Letters of Credit, or the Canadian Revolving Credit Commitment
Termination Date, in the case of Canadian Letters of Credit; provided that so
long as no Event of Default has occurred and is continuing, any Letter of Credit
that expires prior to the US Revolving Credit Commitment Termination Date or the
Canadian Revolving Credit Commitment Termination Date, as applicable, may be
renewed at the request of the applicable Borrower for a term of up to one year
(or, if shorter, for a term expiring on the US Revolving Credit Commitment
Termination Date, in the case of US Letters of Credit, or the Canadian Revolving
Credit Commitment Termination Date, in the case of Canadian Letters of Credit).

            (d) Each Letter of Credit shall be subject to the Uniform Customs
and, to the extent not inconsistent therewith, the laws of the State of New
York, in the case of US Letters of Credit, and the laws of the Province of
Ontario and the laws of Canada applicable thereto, in the case of Canadian
Letters of Credit.

            (e) Neither Issuing Lender shall at any time be obligated to issue
any Letter of Credit hereunder if such issuance would conflict with, or cause
such Issuing Lender or any L/C Participant to exceed any limits imposed by, any
applicable Requirement of Law.

            3.2 Procedure for Issuance of Letters of Credit. (a) The Company may
from time to time request that the US Issuing Lender issue a US Letter of Credit
by delivering to the US Issuing Lender at its address for notices specified

other certificates, documents and other papers and information relating thereto)
by issuing the original of such US Letter of Credit to the beneficiary thereof
or as otherwise may be agreed by the US Issuing Lender and the Company. The US
Issuing Lender shall furnish a copy of such US Letter of Credit to the Company
promptly following the issuance thereof.

            (b) The Canadian Borrower may from time to time request that the
Canadian Issuing Lender issue a Canadian Letter of Credit by delivering to the
Canadian Issuing Lender at its address for notices specified herein an
Application therefor, completed to the reasonable satisfaction of the Canadian
Issuing Lender, and such other certificates, documents and other papers and
information as the Canadian Issuing Lender may reasonably request. Upon receipt
of any Application, the Canadian Issuing Lender will process such Application

Credit earlier than three Business Days after its receipt of the Application
therefor and all such other certificates, documents and other papers and
information relating thereto) by issuing the original of such Canadian Letter of
Credit to the beneficiary thereof or as otherwise may be agreed by the Canadian
Issuing Lender and the Canadian Borrower. The Canadian Issuing Lender shall
furnish a copy of such Canadian Letter of Credit to the Canadian Borrower
promptly following the issuance thereof.

            3.3 Fees, Commissions and Other Charges. (a) The Company shall pay
to the US Administrative Agent, for the account of the US Issuing Lender and the
US L/C Participants, a letter of credit fee with respect to each US Letter of
Credit, computed for the period from and including the date of issuance of such
US Letter of Credit to the expiration date of such US Letter of Credit, computed
at a rate per annum equal to the Applicable Margin then in effect for Eurodollar
Loans that are US Revolving Credit Loans calculated on the basis of the actual
number of days elapsed over a 360-day year, of the aggregate face amount of US
Letters of Credit outstanding, payable in arrears on each L/C Fee Payment Date
and on the US Revolving Credit Commitment Termination Date. Such fee shall be
payable to the US Administrative Agent to be shared ratably among the US
Revolving Credit Lenders in accordance with their respective US Revolving Credit
Commitment Percentages. In addition, the Company shall pay to the US Issuing
Lender, for its own account a fee equal to 0.25% per annum of the aggregate
<PAGE>   51
                                                                              45


face amount of outstanding US Letters of Credit, payable quarterly in arrears on
each L/C Fee Payment Date and on the US Revolving Credit Commitment Termination
Date and calculated on the basis of the actual number of days elapsed over a
360-day year.

            (b) The Canadian Borrower shall pay to the Canadian Administrative
Agent, for the account of the Canadian Issuing Lender and the Canadian L/C
Participants, a letter of credit fee with respect to each Canadian Letter of
Credit, computed for the period from and including the date of issuance of such
Canadian Letter of Credit to the expiration date of such Canadian Letter of
Credit, computed at a rate per annum equal to the Applicable Margin then in
effect for Bankers' Acceptances that are Canadian Revolving Credit Loans
calculated on the basis of the actual number of days elapsed over a 365-day
year, of the aggregate face amount of Canadian Letters of Credit outstanding,
payable annually in advance on the date of issuance of each Canadian Letter of
Credit and on each anniversary thereof to occur thereafter on which a Canadian
Letter of Credit shall remain outstanding. Such fee shall be payable to the
Canadian Administrative Agent to be shared ratably among the Canadian Revolving
Credit Lenders in accordance with their respective Canadian Revolving Credit
Commitment Percentages. In addition, the Canadian Borrower shall pay to the
Canadian Issuing Lender, for its own account, a fee equal to 0.25% per annum of
the aggregate face amount of outstanding Canadian Letters of Credit, payable
quarterly in advance on the date of issuance of each Canadian Letter of Credit
and on each L/C Fee Payment Date to occur thereafter on which a Canadian Letter
of Credit shall remain outstanding and calculated on the basis of the actual
number of days elapsed over a 365-day year.

            (c) In addition to the foregoing fees and commissions, each Borrower
shall pay or reimburse the US Issuing Lender, in the case of the Company, and
the Canadian Issuing Lender, in the case of the Canadian Borrower, for such
normal and customary costs and expenses as are incurred or charged by such
Issuing Lender in issuing, effecting payment under, amending or otherwise
administering any Letter of Credit.

            (d) Each Administrative Agent shall, promptly following its receipt
thereof, distribute to the applicable Issuing Lender and the applicable L/C
Participants all fees and commissions received by such Administrative Agent for
their respective accounts pursuant to this subsection.

            3.4 L/C Participations. (a) The US Issuing Lender irrevocably agrees
to grant and hereby grants to each US L/C Participant, and, to induce the US
Issuing Lender to issue US Letters of Credit hereunder, each US L/C Participant
irrevocably agrees to accept and purchase and hereby accepts and purchases from
the US Issuing Lender, on the terms and conditions hereinafter stated, for such
US L/C Participant's own account and risk an undivided interest equal to such US
L/C Participant's US Revolving Credit Commitment Percentage in the US Issuing
Lender's obligations and rights under each US Letter of Credit issued hereunder
and the amount of each draft paid by the US Issuing Lender thereunder. Each US
L/C Participant unconditionally and irrevocably agrees with the US Issuing
Lender that, if a draft is paid under any US Letter of Credit for which the US
Issuing Lender is not reimbursed in full by the Company in accordance with the
terms of this Agreement, such US L/C Participant shall pay to the US Issuing
Lender upon demand at the US Issuing Lender's address for notices specified
herein an amount equal to such US L/C Participant's US Revolving Credit
Commitment Percentage of the amount of such draft, or any part thereof, which is
not so reimbursed; provided
<PAGE>   52
                                                                              46


that, if such demand is made prior to 12:00 Noon, New York City time, on a
Business Day, such US L/C Participant shall make such payment to the US Issuing
Lender prior to the end of such Business Day and otherwise such US L/C
Participant shall make such payment on the next succeeding Business Day.

            (b) The Canadian Issuing Lender irrevocably agrees to grant and
hereby grants to each Canadian L/C Participant, and, to induce the Canadian
Issuing Lender to issue Canadian Letters of Credit hereunder, each Canadian L/C
Participant irrevocably agrees to accept and purchase and hereby accepts and
purchases from the Canadian Issuing Lender, on the terms and conditions
hereinafter stated, for such Canadian L/C Participant's own account and risk an
undivided interest equal to such Canadian L/C Participant's Canadian Revolving
Credit Commitment Percentage in the Canadian Issuing Lender's obligations and
rights under each Canadian Letter of Credit issued hereunder and the amount of
each draft paid by the Canadian Issuing Lender thereunder. Each Canadian L/C
Participant unconditionally and irrevocably agrees with the Canadian Issuing
Lender that, if a draft is paid under any Canadian Letter of Credit for which
the Canadian Issuing Lender is not reimbursed in full by the Canadian Borrower
in accordance with the terms of this Agreement, such Canadian L/C Participant
shall pay to the Canadian Issuing Lender upon demand at the Canadian Issuing
Lender's address for notices specified herein an amount equal to such Canadian
L/C Participant's Canadian Revolving Credit Commitment Percentage of the amount
of such draft, or any part thereof, which is not so reimbursed; provided that,
if such demand is made prior to 12:00 Noon, Toronto time, on a Business Day,
such Canadian L/C Participant shall make such payment to the Canadian Issuing
Lender prior to the end of such Business Day and otherwise such Canadian L/C
Participant shall make such payment on the next succeeding Business Day.

            (c) If any amount required to be paid by any L/C Participant to any
Issuing Lender pursuant to subsection 3.4(a) or 3.4(b) in respect of any
unreimbursed portion of any payment made by such Issuing Lender under any Letter
of Credit is paid to such Issuing Lender within three Business Days after the
date such payment is due, such L/C Participant shall pay to such Issuing Lender
on demand an amount equal to the product of (i) such amount, times (ii) the
daily average Federal Funds Rate, in the case of US Letters of Credit, and the
then effective CDOR Rate, in the case of Canadian Letters of Credit, as quoted
by such Issuing Lender, during the period from and including the date such
payment is required to the date on which such payment is immediately available
to such Issuing Lender, times (iii) a fraction the numerator of which is the
number of days that elapse during such period and the denominator of which is
360. If any such amount required to be paid by any L/C Participant pursuant to
subsection 3.4(a) or 3.4(b) is not in fact made available to such Issuing Lender
by such L/C Participant within three Business Days after the date such payment
is due, such Issuing Lender shall be entitled to recover from such L/C
Participant, on demand, such amount with interest thereon calculated from such
due date at the rate per annum applicable to ABR Loans, in the case of the US
Issuing Lender, or C$ Prime Loans, in the case of the Canadian Issuing Lender,
hereunder. A certificate of an Issuing Lender submitted to any L/C Participant
with respect to any amounts owing under this subsection shall be conclusive in
the absence of manifest error.

            (d) Whenever, at any time after any Issuing Lender has made payment
under any Letter of Credit and has received from any L/C Participant its pro
rata share of such payment in accordance with subsection 3.4(a) or 3.4(b), such
Issuing Lender receives any payment related to such Letter of Credit (whether
directly from the applicable Borrower or otherwise, including
<PAGE>   53
                                                                              47


proceeds of collateral applied thereto by such Issuing Lender), or any payment
of interest on account thereof, such Issuing Lender will distribute to such L/C
Participant its pro rata share thereof; provided, however, that in the event
that any such payment received by such Issuing Lender shall be required to be
returned by such Issuing Lender, such L/C Participant shall return to such
Issuing Lender the portion thereof previously distributed by such Issuing Lender
to it.

            3.5 L/C Reimbursement Obligations of the Borrower. (a) The Company
agrees to reimburse the US Issuing Lender, and the Canadian Borrower agrees to
reimburse the Canadian Issuing Lender, on each date on which such Issuing Lender
notifies such Borrower of the date and amount of a draft presented under any
Letter of Credit and paid by such Issuing Lender for the amount of (i) such
draft so paid and (ii) any taxes, fees, charges or other costs or expenses
incurred by such Issuing Lender in connection with such payment. Each such
payment shall be made to such Issuing Lender at its address for notices
specified herein in US$, in the case of the US Issuing Lender, and in C$, in the
case of the Canadian Issuing Lender, and in immediately available funds.

            (b) Interest shall be payable by each Borrower on any and all
amounts remaining unpaid by such Borrower under this subsection from the date
such amounts become payable (whether at stated maturity, by acceleration or
otherwise) until payment in full at the rate which would be payable on any
outstanding ABR Loans, in the case of the Company, and C$ Prime Loans, in the
case of the Canadian Borrower, in each case which were then overdue.

            (c) Each drawing under any Letter of Credit shall constitute a
request by the Borrower that is the account party in respect thereof to the
applicable Administrative Agent for a borrowing pursuant to subsection 2.5 of
ABR Loans, in the case of US Letters of Credit, or a borrowing pursuant to
subsection 2.6 of C$ Prime Loans, in the case of Canadian Letters of Credit, in
the amount of such drawing. The Borrowing Date with respect to such borrowing
shall be the date of such drawing.

            3.6 Obligations Absolute. (a) Each Borrower's obligations under this
Section 0 shall be absolute and unconditional under any and all circumstances
and irrespective of any set-off, counterclaim or defense to payment which such
Borrower may have or have had against any Issuing Lender or any beneficiary of a
Letter of Credit.

            (b) The Company also agrees with the US Issuing Lender, and the
Canadian Borrower agrees with the Canadian Issuing Lender, that such Issuing
Lender shall not be responsible for, and such Borrower's L/C Reimbursement
Obligations under subsection 0 shall not be affected by, among other things, (i)
subject to subsection 3.7, the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or (ii) any dispute between or among such
Borrower and any beneficiary of any Letter of Credit or any other party to which
such Letter of Credit may be transferred or (iii) any claims whatsoever of such
Borrower against any beneficiary of such Letter of Credit or any such
transferee.

            (c) No Issuing Lender shall be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except for
errors or omissions caused by such Issuing Lender's gross negligence or willful
misconduct.
<PAGE>   54
                                                                              48


            (d) Each Borrower agrees that any action taken or omitted by either
Issuing Lender under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial Code of the State of New York and the Uniform Customs, in the case of
US Letters of Credit, or the laws of the Province of Ontario and the Uniform
Customs, in the case of Canadian Letters of Credit, shall be binding on such
Borrower and shall not result in any liability of such Issuing Lender to such
Borrower.

            3.7 Letter of Credit Payments. If any draft shall be presented for
payment under any Letter of Credit, the Issuing Lender in respect thereof shall

            (e) Interest shall be payable in arrears on each Interest Payment
Date, provided that interest accruing pursuant to paragraph (d) of this
subsection shall be payable from time to time on demand. Interest in respect of
US$ Loans (and all other amounts denominated in US$) shall be payable in US$,
and interest in respect of Canadian Revolving Credit Loans (and all other
amounts denominated in C$) shall be payable in C$.

            (f) (i) If any provision of this Agreement would obligate any Loan
Party to make any payment of interest or other amount payable to any Lender in
an amount or calculated at a rate which would be prohibited by law or would
result in a receipt by such Lender of interest at a criminal rate (as such terms
are construed under the Criminal Code (Canada)), then notwithstanding such
provision, such amount or rate shall be deemed to have been adjusted with
retroactive effect to the maximum amount or rate of interest, as the case may
be, as would not be so prohibited by law or so result in a receipt by such
Lender of interest at a criminal rate, such adjustment to be effected, to the
extent necessary, as follows:

      (x)   first, by reducing the amount or rates of interest required to be
            paid under this subsection 4.1; and

      (y)   thereafter, by reducing any fees, commissions, premiums and other
            amounts which would constitute interest for purposes of Section 347
            of the Criminal Code (Canada).

            (ii) If, notwithstanding the provisions of clause (i) of this
subsection 4.1(f), and after giving effect to all adjustments contemplated
thereby, any Lender shall have received an amount in excess of the maximum
permitted by such clause, then the applicable Loan Party shall be entitled, by
notice in writing to such Lender, to obtain reimbursement from such Lender of an
amount equal to such excess, and, pending such reimbursement, such amount shall
be deemed to be an amount payable by such Lender to such Loan Party.

            (iii) Any amount or rate of interest referred to in this subsection
4.1(f) shall be determined in accordance with generally accepted actuarial
practices and principles as an effective annual rate of interest over the term
of any Loan on the assumption that any charges, fees or expenses that fall
within the meaning of "interest" (as defined in the Criminal Code (Canada))
shall, if they relate to a specific period of time, be prorated over that period
of time and otherwise be prorated over the period from the Closing Date to the
Canadian Revolving Credit Termination Date or the scheduled final maturity of
the Canadian Term Loans and, in the event of dispute, a certificate of a Fellow
of the Canadian Institute of Actuaries appointed by the Canadian Administrative
Agent shall be conclusive for the purposes of such determination absent manifest
error.

            4.2 Optional Prepayments. (a) Each Borrower may at any time and from
time to time prepay the Loans made to it in whole or in part, without premium or
penalty on any Business Day, provided that (i) the Borrower shall have given (x)

C$100,000, as the case may be, in excess thereof. Upon the receipt of any such
notice the relevant Administrative Agent shall promptly notify each of the
relevant Lenders thereof. If any such notice is given, the amount specified in
such notice shall be due and payable on the date specified therein, together
with any amounts payable pursuant to subsection 4.12, if any, and, in the case
of prepayments of the US Term Loans only, accrued interest to such date on the

at which time an amount equal to 100% of such unapplied Net Cash Proceeds shall

4.3(f), and (ii) such Borrower may notify the relevant Administrative Agent in
writing that it intends to use the Net Cash Proceeds from any such asset sale or
other disposition to acquire fixed or capital assets within 269 days of receipt

such Net Cash proceeds shall not be so used; provided, further, that such Net
Cash Proceeds from any such asset sales or other disposition to the extent that
they may be used for the purposes described in clause (ii) of the immediately
preceding proviso within 269 days of receipt thereof shall either (x) be applied
to prepay any then outstanding Revolving Credit Loans of the relevant Class (in
which case such amount (or a portion thereof) may only be reborrowed on the date
upon which such amount (or such portion thereof) is used for the purposes

sentence, the Aggregate Outstanding US Revolving Extensions of Credit with
respect to all US Revolving Credit Lenders exceeds the aggregate US Revolving
Credit Commitments then in effect, the Company shall, without notice or demand,

Administrative Agent shall return to the US Borrower the cash used to cash
collateralize such then outstanding L/C Obligations pursuant to the second

Canadian Administrative Agent shall return to the Canadian Borrower the cash
used to cash collateralize such respective then outstanding Bankers' Acceptances
and Canadian L/C Obligations pursuant to the preceding sentence.

            (f) (i) Prepayments of the Loans and permanent reductions of the
Revolving Credit Commitments by the Company pursuant to subsections 4.3(a), (b),
(c), (d) and (f)(ii) shall be applied, first, to payment of the US Term Loans
then outstanding, second, (to the extent that there are no US Term Loans then

shall, to the extent of such unapplied amount, be obligated to make a prepayment
of the Canadian Revolving Credit Loans and a permanent reduction of the Canadian
Revolving Credit Commitments in accordance with subsection 4.3(f)(ii). Such
prepayments of the US Term Loans pursuant to subsections 4.3(a), (b), (c), (d)
and (f)(ii) shall be applied to the respective installments of principal thereof
in the inverse order of the respective maturity dates thereof.

            (ii) Prepayments of the Loans and permanent reductions of the
Revolving Credit Commitments by the Canadian Borrower pursuant to subsections
4.3 (a), (b), (c), (d) and (f)(i) shall be applied, first, to payment of the
Canadian Term Loans then outstanding (it being understood that such amounts
shall be deemed to be applied ratably to the portion of the Canadian Term Loans
that are continued on the Closing Date and the portion thereof borrowed on the
Closing Date), second, (to the extent that there are no Canadian Term Loans then
outstanding) to permanent reduction of the Canadian Revolving Credit Commitments
then in effect, and, if any such amount remains unapplied, the Company shall, to
the extent of such unapplied amount, be obligated to make a prepayment of the US
Term Loans and a permanent reduction of the US Revolving Credit Commitments in
accordance with subsection 4.3(f)(i). Such prepayments of the Canadian Term
Loans pursuant to subsections 4.3(a), (b), (c), (d) and (f)(i) shall be applied,
subject to the limitations set forth in clause (f)(iii) below, to the respective
installments of principal thereof in the inverse order of the respective
maturity dates thereof.

            (iii) Notwithstanding any other provision of this subsection 4.3, at
no time during the period from the Closing Date through the first day following
the fifth anniversary of the Closing Date (unless the Canadian Term Loans shall
have become due and payable by acceleration under this Agreement following the
occurrence of an Event of Default) shall any prepayments of the Canadian Term
Loans be required to be made by the Canadian Borrower pursuant to this
subsection 4.3 to the extent that, after giving effect to such prepayment, the
sum of (A) the aggregate amount of prepayments of Canadian Term Loans made
pursuant to subsection 4.3 at or prior to such first day (it being understood
that such amounts shall be deemed to be applied ratably to the portion of the

                                                                              54


Canadian Term Loans scheduled to be made pursuant to subsection 2.12 at or prior
to such first day (it being understood that such amounts shall be deemed to be
applied ratably to the portion of the Canadian Term Loans that constitutes the
Closing Date Advance and the portion thereof that constitutes the Original
Advance (as each such term is defined in subsection 2.14(a)) and (ii) the
scheduled repayments of "Canadian Tranche B Term Loans" under (and as defined
in) the Existing Credit Agreement prior to the Closing Date pursuant to
subsection 2.13 of the Existing Credit Agreement (aggregating $200,000, in the
case of this clause (B)(ii)) would exceed an amount equal to 25% of the
aggregate amount of the Closing Date Advance, in the case of such repayments
applied or deemed applied to Canadian Term Loans constituting the Closing Date
Advance, or 25% of the aggregate amount of the Original Advance, in the case of
such repayments applied or deemed applied to Canadian Term Loans constituting
the Original Advance, respectively (as each such term is defined in subsection
2.14(a)).

            (iv) Notwithstanding the foregoing provisions of this subsection
4.3(f) (but subject, nevertheless, to subsection 4.3(f)(iii)), if at the time
any prepayment of the Loans and permanent reductions of the Revolving Credit
Commitments shall be required to be made pursuant to the provisions of
subsection 4.3(a), (b), (c), (d), (f)(i) or (f)(ii) an Event of Default shall
have occurred and be continuing, such prepayment shall be applied to the payment
of all the Loans and L/C Obligations then outstanding pro rata according to the
respective amounts thereof, and each of the Revolving Credit Commitments shall
be automatically reduced by an amount equal to that portion of such prepayments
as shall have been allocated to the Revolving Credit Loans and L/C Obligations
then outstanding under such Revolving Credit Commitment. For purposes of
calculations pursuant to this clause (v) all amounts denominated in Canadian
Dollars shall be converted to US Dollars at the US$ Equivalent amount thereof.
Prepayments, pursuant to this clause (iv) in respect of the US Term Loans and US
Revolving Credit Loans shall be made by the Company, and prepayments pursuant to
this clause (iv) in respect of the Canadian Term Loans and Canadian Revolving
Credit Loans shall be made by the Canadian Borrower.

            (g) Notwithstanding anything to the contrary contained above, all
prepayments of each Loan shall be made in the currency in which such Loans were
made, all cash collateralization of Canadian L/C Obligations and Bankers'
Acceptances shall be made in Canadian Dollars and all cash collateralization of
US L/C Obligations shall be made in US Dollars. For purposes of determining the
amounts required to be applied, conversions of one currency to another are
assumed to be made by using the C$ Equivalent or US$ Equivalent, as the case may
be, of amounts received in the other currency. However, it shall remain the
responsibility of the respective Borrower to convert amounts received in one
currency into the other to the extent needed to repay, or cash collateralize,
Loans, L/C Obligations or Bankers' Acceptances maintained in the other such
currency.

            (h) Amounts prepaid on account of Term Loans pursuant to this
subsection may not be reborrowed. Each prepayment pursuant to this subsection
shall be accompanied by payment of accrued interest on the amount prepaid.
Amounts prepaid on account of Canadian Term Loans shall be deemed to be applied
ratably to the portion of the Canadian Term Loans that constitutes the Closing
Date Advance and the portion thereof that constitutes the Original Advance (as
each such term is defined in subsection 2.14(a).

            4.4 Conversion and Continuation Options. (a) Each Borrower may elect
from time to time to convert Eurodollar Loans to ABR Loans by giving the US
Administrative Agent

at least three Business Days,' prior irrevocable notice of such election,
provided that any such conversion of Eurodollar Loans may only be made on the
last day of an Interest Period with respect thereto. Each Borrower may elect

Administrative Agent or the Canadian Administrative Agent, as applicable, at
least three Business Days prior irrevocable notice of such election. Any such
notice of conversion to Eurodollar Loans shall specify the length of the initial
Interest Period or Interest Periods therefor. Upon receipt of any such notice,
such Administrative Agent shall promptly notify each Lender thereof. All or any
part of outstanding Eurodollar Loans and ABR Loans may be converted as provided
herein, provided that (i) no Loan may be converted into a Eurodollar Loan when
any Event of Default has occurred and is continuing and the US Administrative
Agent has or the Majority Lenders have determined that such a conversion is not
appropriate and (ii) no Loan may be converted into a Eurodollar Loan after the
date that is one month prior to the US Revolving Credit Termination Date (in the
case of conversions of US Revolving Credit Loans) or the date of the final
installment of principal of the Class of Term Loans of which such Loan is a
part.

            (b) Any Eurodollar Loans may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
applicable Borrower giving notice to the applicable Administrative Agent, in
accordance with the applicable provisions of the term "Interest Period" set
forth in subsection 1.1, of the length of the next Interest Period to be
applicable to such Loans, provided that no Eurodollar Loan may be continued as
such (i) when any Event of Default has occurred and is continuing and either
Administrative Agent has or the Majority Lenders have determined that such a
continuation is not appropriate or (ii) after the date that is one month prior
to the US Revolving Credit Commitment Termination Date (in the case of
conversions of US Revolving Credit Loans) or the date of the final installment
of principal of the Class of Term Loans of which such Loan is a part, and
provided, further, that if either Borrower shall fail to give any required
notice as described above in this paragraph or if such continuation is not
permitted pursuant to the preceding proviso such Loans shall be automatically
converted to ABR Loans on the last day of such then expiring Interest Period.

            (c) Subject to the provisions of this Agreement, the Canadian
Borrower may, prior to the Canadian Revolving Credit Termination Date, effective
on any Business Day, convert, in whole or in part, C$ Prime Loans into Bankers'
Acceptances or vice versa upon giving to the Canadian Administrative Agent prior
irrevocable telephone or written notice within the notice period and in the form
which would be required to be given to the Canadian Administrative Agent in
respect of the category of Canadian Revolving Credit Loans into which the
outstanding Canadian Revolving Credit Loans is to be converted in accordance
with the provisions of subsection 2.6 or 2.16, as applicable, followed, in the
case of telephone notice, by written confirmation on the same day, provided
that:

       (a)  no C$ Prime Loan may be converted into a Bankers' Acceptance when
            any Event of Default has occurred and is continuing and the Canadian
            Administrative Agent has or the Majority Lenders have determined
            that such conversion is not appropriate;

       (b)  each conversion to Bankers' Acceptances shall be for an aggregate
            amount of C$4,000,000 (and whole multiples of C$100,000 in excess
            thereof), and each

            conversion to C$ Prime Loans shall be in a minimum aggregate amount
            of C$4,000,000; and

       (c)  Bankers' Acceptances may be converted only on the maturity date of
            such Bankers' Acceptances and, provided that, if less than all
            Bankers' Acceptances are converted, then after such conversion not
            less than C$4,000,000 (and whole multiples of C$100,000 in excess
            thereof) shall remain as Bankers' Acceptances.

            4.5 Minimum Amounts and Maximum Number of Tranches. All borrowings,
conversions and continuations of US$ Loans hereunder and all selections of
Interest Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Loans comprising each Tranche shall be equal to US$2,500,000 or a whole
multiple of US$100,000 in excess thereof. In no event shall there be more than
(a) 30 Tranches outstanding at any time or (b) 20 Tranches in respect of US
Revolving Credit Loans, 15 Tranches in respect of US Term Loans or 10 Tranches
in respect of Canadian Term Loans outstanding at any time. Notwithstanding the
foregoing and regardless of the number of Tranches outstanding, all Term Loans
shall be advanced only once, and all amounts repaid thereunder may not be
reborrowed.

            4.6 Computation of Interest and Fees. (a) Interest (except as
provided in the following two sentences) and commitment and letter of credit
fees and commissions shall be calculated on the basis of a 360-day year for the
actual days elapsed. Interest on ABR Loans (when it is based upon the CIBC Base
Rate) shall be calculated on the basis of a 365- (or 366-, as the case may be)
day year for the actual days elapsed. Acceptance fees and commitment fees and
interest calculated on the basis of the CDOR Rate shall be calculated on the
basis of a 365-day year for the actual days elapsed. The relevant Administrative
Agent shall as soon as practicable notify the relevant Borrower and the Lenders
of each determination of a Eurodollar Rate or the Applicable BA Discount Rate.
Any change in the interest rate on a Loan resulting from a change in the ABR,
the C$ Prime Rate or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change becomes
effective. The relevant Administrative Agent shall as soon as practicable notify
the relevant Borrower and the relevant Lenders of the effective date and the
amount of each such change in interest rate.

            (b) Each determination of an interest rate by an Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the relevant Borrower and the Lenders in the absence of manifest
error. The relevant Administrative Agent shall, at the request of the relevant
Borrower, deliver to such Borrower a statement showing the quotations used by
the such Administrative Agent in determining any interest rate pursuant to
subsection 4.1.

            (c) For the purposes of the Interest Act (Canada), in any case in
which an interest rate is stated in this Agreement to be calculated on the basis
of a year of 360 days or 365 days, as the case may be, the yearly rate of
interest to which such interest rate is equivalent is equal to such interest
rate multiplied by the number of days in the year in which the relevant interest
payment accrues and divided by 360 or 365, respectively. In addition, the
principle of deemed reinvestment of interest does not apply to any interest
calculations under this Agreement and the rates of interest stipulated in this
Agreement are intended to be nominal rates and not effective rates or yields.

            4.7 Inability to Determine Interest Rate. If prior to the first day
of any Interest Period:

            (a) the US Administrative Agent shall have determined (which
      determination shall be conclusive and binding upon the Borrower in the
      absence of manifest error) that, by reason of circumstances affecting the
      relevant market, adequate and reasonable means do not exist for
      ascertaining the Eurodollar Rate for such Interest Period, or

            (b) the US Administrative Agent shall have received notice from the
      Majority Lenders that the Eurodollar Rate determined or to be determined
      for such Interest Period will not adequately and fairly reflect the cost
      to such US$ Lenders (as conclusively certified by such US$ Lenders) of
      making or maintaining their affected Loans during such Interest Period,

the US Administrative Agent shall give telecopy or telephonic notice thereof to
the Borrowers and the US$ Lenders as soon as practicable thereafter. If such
notice is given (x) any Eurodollar Loans requested to be made on the first day
of such Interest Period shall be made as ABR Loans, (y) any Loans that were to
have been converted on the first day of such Interest Period to Eurodollar Loans
shall be converted to or continued as ABR Loans and (z) any outstanding
Eurodollar Loans shall be converted, on the first day of such Interest Period,
to ABR Loans. Until such notice has been withdrawn by the US Administrative
Agent, no further Eurodollar Loans shall be made or continued as such, nor shall
either Borrower have the right to convert Loans to Eurodollar Loans.

            4.8 Pro Rata Treatment and Payments. (a) Each borrowing of Revolving
Credit Loans by each Borrower hereunder shall be made, each payment by each
Borrower on account of any commitment fee or acceptance fee hereunder, and any
reduction of the Revolving Credit Commitments shall be allocated by the relevant
Administrative Agent, pro rata according to the US Revolving Credit Commitment
Percentages of the US Revolving Credit Lenders, in the case of US Revolving
Credit Commitments and US Revolving Credit Loans, and according to the Canadian
Revolving Credit Commitment Percentages of the Canadian Revolving Credit
Lenders, in the case of Canadian Revolving Credit Commitments and Canadian
Revolving Credit Loans. Each payment (including each prepayment pursuant to
subsection 4.3, but subject to the limitations set forth in subsection
4.3(f)(iii) and subject to the provisions of subsection 4.3(f)(iv)) by each
Borrower on account of principal of and interest on any Class of Loans shall be
made pro rata according to the respective outstanding principal amounts of such
Class of Loans then held by the relevant Lenders. Notwithstanding the foregoing
provisions of this subsection, if at the time of the making of any payment
hereunder of interest, principal or fees such payment shall be insufficient to
pay in full all such amounts then due and unpaid hereunder, such amount shall be
applied first to pay all fees then due and unpaid, second to pay all interest
then due and unpaid and third to pay all principal then due and unpaid in each
case described above, ratably among the Lenders in accordance with the
respective amounts of each category of obligation then due and unpaid to it,
provided that, unless all the Loans shall have become due and payable (whether
at the stated maturity thereof, by acceleration or otherwise), in no event shall
any amount paid by either Borrower under or pursuant to this Agreement be
applied to the obligations of any Class of Loans in respect of which the obligor
is the other Borrower. All payments (including prepayments) to be made by the
Borrowers hereunder and under any Notes, whether on account
<PAGE>   64
                                                                              58


of principal, interest, fees, L/C Obligations or otherwise, shall be made
without set-off or counterclaim and shall be made prior to 12:00 Noon, New York
City time, on the due date thereof to the relevant Administrative Agent, for the
account of the Lenders holding the relevant Loans or the L/C Participants, as
the case may be, at the Administrative Agent's office specified in subsection
11.2, in US Dollars or C$, as the case may be, and in immediately available
funds. Payments received by the relevant Administrative Agent after such time
shall be deemed to have been received on the next Business Day. If any payment
hereunder (other than payments on Eurodollar Loans) becomes due and payable on a
day other than a Business Day, the maturity of such payment shall be extended to
the next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension. If any payment on a Eurodollar Loan becomes due and payable on a day
other than a Business Day, the maturity of such payment shall be extended to the
next succeeding Business Day (and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension) unless the result of such extension would be to extend such payment
into another calendar month, in which event, subject to subsection 4.3(f)(iii),
such payment shall be made on the immediately preceding Business Day.

            (b) Unless the relevant Administrative Agent shall have been
notified in writing by any Lender prior to a borrowing that such Lender will not
make the amount that would constitute its Commitment Percentage of such
borrowing available to such Administrative Agent, such Administrative Agent may
assume that such Lender is making such amount available to such Administrative
Agent, and such Administrative Agent may, in reliance upon such assumption, make
available to the relevant Borrower a corresponding amount. If such amount is not
made available to such Administrative Agent by the required time on the
Borrowing Date therefor, such Lender shall pay to such Administrative Agent, on
demand, such amount with interest thereon at a rate equal to the daily average
Federal Funds Rate (in the case of US$ Loans) or at the then effective CDOR Rate
(in the case of Canadian Revolving Credit Loans) for the period until such
Lender makes such amount immediately available to such Administrative Agent. A
certificate of the relevant Administrative Agent submitted to any Lender with
respect to any amounts owing under this subsection shall be conclusive in the
absence of manifest error. If such Lender's Commitment Percentage of such
borrowing is not made available to the relevant Administrative Agent by such
Lender within three Business Days of such Borrowing Date, the relevant
Administrative Agent shall also be entitled to recover such amount with interest
thereon at the rate per annum applicable to ABR Loans or C$ Prime Loans, as the
case may be, hereunder, on demand, from the relevant Borrower.

            4.9 Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or any change in the
interpretation or application thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the
commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert ABR Loans to Eurodollar Loans shall
forthwith be cancelled and (b) such Lender's Loans then outstanding as
Eurodollar Loans, if any, shall be converted automatically to ABR Loans on the
respective last days of the then current Interest Periods with respect to such
Loans or within such earlier period as required by law. If any such conversion
of a Eurodollar Loan occurs on a day which is not the last day of the then
current Interest Period with respect thereto, the relevant Borrower shall pay to
such Lender such amounts, if any, as may be required pursuant to subsection
4.12.

                                                                              59


            4.10 Requirements of Law. (a) If the adoption of or any change in
any Requirement of Law or any change in the interpretation or application
thereof or compliance by any Lender with any request or directive (whether or
not having the force of law) from any central bank or other Governmental
Authority made subsequent to the date hereof:

            (i) shall subject any Lender to any tax of any kind whatsoever with
      respect to this Agreement, any Note, any Letter of Credit, any Application
      or any Eurodollar Loan made by it, or any Bankers' Acceptance purchased or
      accepted by it, or change the basis of taxation of payments to such Lender
      in respect thereof (except for Non-Excluded Taxes covered by subsection
      4.11 and changes in the rate of tax on the overall net income of such
      Lender);

            (ii) shall impose, modify or hold applicable any reserve, special
      deposit, compulsory loan or similar requirement against assets held by,
      deposits or other liabilities in or for the account of, advances, loans or
      other extensions of credit by, or any other acquisition of funds by, any
      office of such Lender which is not otherwise included in the determination
      of the Eurodollar Rate or the BA Discount Rate hereunder; or

                  (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans, or issuing or participating in
Letters of Credit, or purchasing or accepting Bankers' Acceptances, or to reduce
any amount receivable hereunder in respect thereof then, in any such case, the
relevant Borrower shall promptly pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender, on an after-tax basis,
for such increased cost or reduced amount receivable.

            (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or any change in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof does or shall have the effect of
reducing the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Lender or such corporation could have achieved but
for such change or compliance (taking into consideration such Lender's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
such Lender to be material, then from time to time, after submission by such
Lender to the relevant Borrower (with a copy to the US Administrative Agent) of
a written request therefore, such Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender, on an after-tax
basis, for such reduction.

            (c) If any Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the relevant Borrower,
through the relevant Administrative Agent, of the event by reason of which it
has become so entitled. A certificate as to any additional amounts payable
pursuant to this subsection submitted by such Lender, through the relevant
Administrative Agent, to the relevant Borrower shall be conclusive in the
absence of
<PAGE>   66
                                                                              60


manifest error. This covenant shall survive the termination of this Agreement
and the payment of the Notes and all other amounts payable hereunder.

            4.11 Taxes. (a) All payments made by either Borrower under this
Agreement, any Note or any Application shall be made free and clear of, and
without deduction or withholding for or on account of, any present or future
income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions
or withholdings, now or hereafter imposed, levied, collected, withheld or
assessed by any Governmental Authority, excluding net income taxes and franchise
taxes (imposed in lieu of net income taxes) imposed on either Administrative
Agent or any Lender as a result of a present or former connection between such
Administrative Agent or such Lender and the jurisdiction of the Governmental
Authority imposing such tax or any political subdivision or taxing authority
thereof or therein (other than any such connection arising solely from the
relevant Administrative Agent or such Lender having executed, delivered or
performed its obligations or received a payment under, or enforced, this
Agreement, any Notes or any Application). If any such non-excluded taxes,
levies, imposts, duties, charges, fees, deductions or withholdings
("Non-Excluded Taxes") are required to be withheld from any amounts payable to
either Administrative Agent or any Lender hereunder or under any Note or any
Application, the amounts so payable to the Administrative Agent or such Lender
shall be increased to the extent necessary to yield to such Administrative Agent
or such Lender (after payment of all Non-Excluded Taxes) interest or any such
other amounts payable hereunder at the rates or in the amounts specified in this
Agreement, the Notes and the Applications, provided, however, that neither
Borrower shall be required to increase any such amounts payable to any Lender if
such increased amount arises as a result of (i) in the case of amounts payable
by the Company with respect to US$ Loans, such Lender's failure to comply with
any applicable requirements of subsection 4.11(b), including a material failure
of any statement or certification given pursuant to subsection 4.11(b) to be
true for any reason other than a change in United States federal income tax law
or an amendment, modification or revocation of an applicable double tax treaty
or (ii) in the case of amounts payable by the Canadian Borrower with respect to
Canadian Revolving Credit Loans, such Lender's status as a non-resident of
Canada for the purposes of the Income Tax Act (Canada). Each Borrower shall also
indemnify each Administrative Agent and each Lender on an after-tax basis for
any additional taxes on net income which such Administrative Agent or such
Lender, as the case may be, may be obligated to pay as a result of the receipt
of additional amounts under this subsection 4.11(a). Whenever any Non-Excluded
Taxes are payable by either Borrower, as promptly as possible thereafter such
Borrower shall send to the relevant Administrative Agent for its own account or
for the account of such Lender, as the case may be, a certified copy of an
original official receipt received by such Borrower showing payment thereof. If
either Borrower fails to pay any Non-Excluded Taxes when due to the appropriate
taxing authority or fails to remit to the relevant Administrative Agent the
required receipts or other required documentary evidence, such Borrower shall
indemnify each Administrative Agent and the Lenders for any incremental taxes,
interest or penalties that may become payable by such Administrative Agent or
any Lender as a result of any such failure. The agreements in this subsection
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

            (b) Each Lender that is not incorporated under the laws of the
United States of America or a state thereof shall:

                                                                              61


            (i) in the case of a Lender or a Transferee that is a "bank" under
      Section 881(c)(3)(A) of the Code;

                  (A) deliver to Company and the US Administrative Agent (A) two
            duly completed copies of United States Internal Revenue Service Form
            1001 or 4224, or successor applicable form, as the case may be, and
            (B) an Internal Revenue Service Form W-8 or W-9, or successor
            applicable form, as the case may be;

                  (B) deliver to the Company and the US Administrative Agent two
            further copies of any such form or certification on or before the
            date that any such form or certification expires or becomes obsolete
            and after the occurrence of any event requiring a change in the most
            recent form previously delivered by it to the Company; and

                  (C) obtain such extensions of time for filing and complete
            such forms or certifications as may reasonably be requested by the
            Company or the US Administrative Agent;

            (ii) in the case of a Lender or a Transferee that is not a "bank"
      under Section 881(c)(3)(A) of the Code:

                        (A) deliver to the Company and the US Administrative
            Agent (I) a statement under penalties of perjury that such Lender
            (x) is not a "bank" under Section 881(c)(3)(A) of the Code, is not
            subject to regulatory or other legal requirements as a bank in any
            jurisdiction, and has not been treated as a bank for purposes of any
            tax, securities law or other filing or submission made to any
            Governmental Authority, any application made to a rating agency or
            qualification for any exemption from tax, securities law or other
            legal requirements, (y) is not a 10-percent shareholder within the
            meaning of Section 881(c)(3)(B) of the Code and (z) is not a
            controlled foreign corporation receiving interest from a related
            person within the meaning of Section 881(c)(3)(C) of the Code and
            (II) a properly completed and duly executed Internal Revenue Service
            Form W-8 or applicable successor form;

                        (B) deliver to the Company and the US Administrative
            Agent two further properly completed and duly executed copies of
            said Form W-8, or any successor applicable form on or before the
            date that any such Form W-8 expires or becomes obsolete or after the
            occurrence of any event requiring a change in the most recent form
            previously delivered by it to the Company or upon the request of the
            Company; and

                        (C) obtain such extensions of time for filing and
            completing such forms or certifications as may be reasonably
            requested by the Company or the US Administrative Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from
<PAGE>   68
                                                                              62


duly completing and delivering any such form with respect to it and such Lender
so advises the Company and the US Administrative Agent. Such Lender shall
certify (i) in the case of a Form 1001 or 4224, that it is entitled to receive
payments under this Agreement without deduction or withholding of any United
States federal income taxes and (ii) in the case of a Form W-8 or W-9, that it
is entitled to an exemption from United States backup withholding tax. Each
Person that shall become a Lender or a Participant pursuant to subsection 11.6
shall, upon the effectiveness of the related transfer, be required to provide
all of the forms and statements required pursuant to this subsection, provided
that in the case of a Participant such Participant shall furnish all such
required forms and statements to the Lender from which the related participation
shall have been purchased.

            4.12 Indemnity. Each Borrower agrees to indemnify each Lender and to
hold each Lender harmless from any loss or expense which such Lender may sustain
or incur as a consequence of (a) default by such Borrower in making a borrowing
of, conversion into or continuation of Eurodollar Loans after such Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by such Borrower in making any prepayment after such
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (c) the making of a prepayment of Eurodollar Loans on a day which
is not the last day of an Interest Period with respect thereto. Such
indemnification may include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by such Lender) which
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurodollar
market. This covenant shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.


                    SECTION 5. REPRESENTATIONS AND WARRANTIES

            To induce the Lenders to enter into this Agreement and to make the
Loans and issue or participate in the Letters of Credit, the Company hereby
represents and warrants to each Administrative Agent and each Lender that:

            5.1 Financial Condition. (a) The consolidated balance sheet of the
Company and its consolidated Subsidiaries as at December 31, 1996 and the
related consolidated statements of income and of cash flows for the fiscal year
ended on such date, reported on by Deloitte & Touche, copies of which have
heretofore been furnished to each Lender, are complete and correct and present
fairly the consolidated financial condition of the Company and its consolidated
Subsidiaries as at such date, and the consolidated results of their operations
and their consolidated cash flows for the fiscal year then ended. The unaudited
consolidated balance sheet of the Company and its consolidated Subsidiaries as
at March 31, 1997 and the related unaudited consolidated statements of income
and of cash flows for the three-month period ended on such date, certified by a
Responsible Officer, copies of which have heretofore been furnished to each
<PAGE>   69
                                                                              63


Lender, are complete and correct and present fairly the consolidated financial
condition of the Company and its consolidated Subsidiaries as at such date, and
the consolidated results of their operations and their consolidated cash flows
for the three-month period then ended (subject to normal year-end audit
adjustments). All such financial statements, including the related schedules and
notes thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by such accountants or
Responsible Officer, as the case may be, and as disclosed therein). Neither the
Company nor any of its consolidated Subsidiaries had, at the date of the most
recent balance sheet referred to above, any material Guarantee Obligation,
contingent liability or liability for taxes, or any long-term lease or unusual
forward or long-term commitment, including, without limitation, any interest
rate or foreign currency swap or exchange transaction, which is not reflected in
the foregoing statements or in the notes thereto. During the period from
December 31, 1996 to and including the Closing Date there has been no sale,
transfer or other disposition by the Company or any of its consolidated
Subsidiaries of any material part of its business or property and, except for
(i) the Acquisition, (ii) the acquisition of the stock of Outdoor Systems (New
York), Inc. (formerly known as Van Wagner Communications, Inc.) and (iii) any
other acquisition disclosed to the Lenders in the Confidential Information
Memorandum delivered in connection herewith, no purchase or other acquisition of
any business or property (including any capital stock of any other Person)
material in relation to the consolidated financial condition of the Company and
its consolidated Subsidiaries at December 31, 1996.

            (b) The NAC financial statements referred to in Section 2.03 of the
Purchase Agreement, copies of which have heretofore been furnished to each
Lender, present fairly the consolidated financial condition of the business,
operations and assets of NAC as at the respective dates thereof, and the
consolidated results of operations and consolidated cash flows thereof for the
fiscal periods then ended.

            (c) The pro forma balance sheet of the Company and its consolidated
Subsidiaries (the "Pro Forma Balance Sheet"), copies of which have heretofore
been furnished to each Lender, is the balance sheet of the Company and its
consolidated Subsidiaries as of December 31, 1996 (the "Pro Forma Date"),
adjusted to give effect (as if such events had occurred on such date) to (i) the
consummation of the Acquisition, (ii) the making of the Loans and other
extensions of credit under this Agreement on the Closing Date and the
Acquisition Closing Date and the application of the proceeds thereof as
contemplated hereby, and (iii) the payment of the fees and expenses payable in

duly qualified as a foreign corporation and in good standing under the laws of
each jurisdiction set forth on Schedule 5.3 on the date hereof, which includes

the failure to be so qualified or in good standing could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect and (d) is in
compliance with all Requirements of Law except to the extent that the failure to
comply therewith could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect.

            5.4 Corporate Power; Authorization; Enforceable Obligations. (a)
Each of the Company and the other Loan Parties has the corporate power and
authority, and the legal right, to make, deliver and perform those Loan

hereunder, and each of the Borrowers and the other Loan Parties has taken all
necessary corporate action to authorize (in the case of each Borrower) the

dealing.

            5.5 No Legal Bar. The execution, delivery and performance of this

its other property, and none of such property is subject to any Lien except as
permitted by subsection 8.3, and except to the extent, in the case of such real
property other than that required to be subject to a Mortgage hereunder, that
the failure to have such good title or leasehold interest, as the case may be,
could not reasonably be expected to have a Material Adverse Effect.

            5.9 Advertising Displays. Schedule 5.9 sets forth, under the heading
"Locations and Leases", on the date hereof, (i) the location by street of each
Advertising Display of the Company or any of its Restricted Subsidiaries, (ii)

meanings of each of the quoted terms under Regulation U of the Board of

                                                                              66


            5.13 ERISA. (a) Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Single
Employer Plan, and each Plan has complied in all material respects with the
applicable provisions of ERISA and the Code where failure to comply could
reasonably be expected to result in a liability to the Company or any Commonly
Controlled Entity. No termination of a Single Employer Plan has occurred, and no
Lien on the property, assets or revenues of the Company or any Commonly
Controlled Entity in favor of the PBGC or a Plan has arisen, during such
five-year period. The present value of all accrued benefits under each Single
Employer Plan (based on those assumptions used to fund such Plans) did not, as
of the last annual valuation date prior to the date on which this representation
is made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits. Neither the Company nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Company nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Company or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization, Insolvent or
terminating where any liability could result from any such event.
Notwithstanding the foregoing, there shall be no breach of the representations
set forth in this subsection hereof unless the amount of any liability of the
Company or any Commonly Controlled Entity which arises or which could be
reasonably expected to arise in connection with such representation,
individually or in the aggregate, exceeds $500,000.

            (b) Each Canadian Pension Plan is in compliance with all applicable
pension benefits and tax laws except to the extent that non-compliance could not
reasonably be expected to have a Material Adverse Effect; no Canadian Pension
Plan has any unfunded liabilities (either on a "going concern" or on a "winding
up" basis and determined in accordance with all applicable laws and using
assumptions and methods that are appropriate in the circumstances and in
accordance with generally accepted actuarial principles and practices in
Canada), all contributions (including any special payments to amortize any
unfunded liabilities) required to be made in accordance with all applicable laws
and the terms of each Canadian Pension Plan have been made; no event has
occurred and no condition exists with respect to any Canadian Pension Plan that
has resulted or could reasonably be expected to result in any Canadian Pension
Plan being ordered or required to be wound up in whole or in part pursuant to
any applicable pension benefits laws or having its registration revoked or
refused for the purposes of any applicable pension benefits or tax laws or being
placed under the administration of any relevant pension benefits regulatory
authority or being required to pay any taxes or penalties under any applicable
pension benefits or tax laws, other than events or conditions that, individually
or in the aggregate, could not reasonably be expected to have a Material Adverse
Effect; no order has been made and no notice has been given pursuant to any
applicable pension benefits or tax laws in respect of any Canadian Pension Plan
requiring (or proposing to require) any Person to take or to refrain from taking
any action in respect thereof or that there has (or there are circumstances that
indicate that there has) been a contravention of any such applicable laws, other
than in respect of matters that, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect; no event has occurred
and no condition exists which has resulted or could reasonably be expected to
result in the Company or any Subsidiary of the Company being required to pay,
repay or refund any material amount (other than contributions required to be
<PAGE>   73
                                                                              67


made or expenses required to be paid in the ordinary course) to or on account of
any Canadian Pension Plan or a current or former member thereof, other than
events or conditions that, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect; and no event has
occurred and no condition exists that has resulted or could result in a material
payment being made out of a guarantee fund established under any applicable
pension benefits laws in respect of a Canadian Pension Plan.

            (c) With respect to any pension, retirement or other deferred
compensation plan maintained by the Canadian Borrower or any of its Subsidiaries
which is not a Canadian Pension Plan, all required contributions have been made,
and there are no unfunded liabilities in respect of such plans (either on a
"going concern" or on a "winding up'" basis and determined in accordance with
all applicable laws and using assumptions and methods that are appropriate in
the circumstances and in accordance with generally accepted actuarial principles
and practices in Canada).

            5.14 Investment Company Act; Other Regulations. Neither Borrower is
an "investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended. Neither
Borrower is subject to regulation under any Federal or State statute or
regulation which limits its ability to incur Indebtedness.

            5.15 Subsidiaries. Schedule 5.15 sets forth each of the Subsidiaries

any assets or has or is subject to any liabilities or Contractual Obligations,

the Borrowers for:

            (a) the continuation of loans under the Existing Credit Agreement as
      set forth herein;

            (b) working capital purposes in the ordinary course of business; and

            (c) the Acquisition and Permitted Acquisitions.

            5.17 Environmental Matters. (a) The facilities and properties owned,
leased or operated by the Company or any of its Subsidiaries (the "Properties")
do not contain, and have not previously contained, any Materials of
Environmental Concern in amounts or concentrations which (i) constitute or
constituted a violation of, or (ii) could reasonably be expected to give rise to
liability under, any Environmental Law except in either case insofar as such
violation or liability, or any aggregation thereof, could not reasonably be
expected to have a Material Adverse Effect.

value thereof.

            (d) Materials of Environmental Concern have not been transported or
disposed of from the Properties in violation of, or in a manner or to a location
which could reasonably be expected to give rise to liability under, any
Environmental Law, nor have any Materials of Environmental Concern been
generated, treated, stored or disposed of at, on or under any of the Properties
in violation of, or in a manner that could reasonably be expected to give rise
to liability under, any applicable Environmental Law except insofar as any such
violation or liability referred to in this paragraph, or any aggregation
thereof, could not reasonably be expected to have Material Adverse Effect.

            (e) No judicial proceeding or governmental or administrative action
is pending or, to the knowledge of the Company, threatened, under any
Environmental Law to which the Company or any Subsidiary is or will be named as
a party with respect to the Properties or the Business, nor are there any
consent decrees or other decrees, consent orders, administrative orders or other
orders, or other administrative or judicial requirements outstanding under any
Environmental Law with respect to the Properties or the Business except insofar
as such proceeding, action, decree, order or other requirement, or any
aggregation thereof, could not reasonably be expected to have a Material Adverse
Effect.

claims which, in the aggregate, could not reasonably be expected to have a
Material Adverse Effect, nor does the Company know of any valid basis for any
such claim. The use of such Intellectual Property by the Company and its
Restricted Subsidiaries does not infringe on the rights of any Person, except

(including, without limitation, its initial extension of credit) is subject to
the satisfaction of the following conditions precedent:

            (a) Representations and Warranties. Each of the representations and
      warranties made by the Company and each other Loan Party in or pursuant to
      the Loan Documents shall be true and correct in all material respects on
      and as of such date as if made on and as of such date except to the extent
      such representations and warranties relate solely to an earlier date,

      representation and warranty set forth in subsection 5.2(a) shall be deemed
      satisfied if (i) subsequent to April 30, 1997 nothing shall have occurred
      which could be reasonably likely to have a material adverse effect on the
      ability of the Company and its Restricted Subsidiaries (including after
      giving effect to the Acquisition) to perform their respective obligations,
      and to avoid a Default or Event of Default, hereunder and under the other
      Loan Documents and the Purchase Agreement, provided that none of (A) the
      matters described in the Disclosure Schedule to the Purchase Agreement,
      assuming no materially adverse development in such matters, (B) actions
      that the Company has agreed to take pursuant to Section 6.04 of the
      Purchase Agreement with respect to obtaining approval for the Acquisition
      under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as
      amended, or (C) any judgment, order, settlement, legislation or regulation
      which has the effect of restricting tobacco advertising, in whole or in
      part, shall constitute a material adverse effect of a type described in
      this clause (i), and (ii) the US Administrative Agent shall not have
      become aware subsequent to April 30, 1997 of any information or other
      matter affecting the Company, NAC or the transactions contemplated hereby
      which is inconsistent in any material manner with any information
      disclosed to it prior to such date, which information or other matter, the
      US Administrative Agent reasonably believes, could be reasonably expected
      to have a material adverse effect on the business, operations, condition
      (financial or otherwise), assets or liabilities of the Company or NAC.

            (b)  No Default.  No Default or Event of Default shall have
      occurred and be continuing on such date or after giving effect to the
      Loans requested to be made on such date.

Each borrowing by and Letter of Credit issued on behalf of either Borrower
hereunder shall constitute a representation and warranty by the Company as of
the date of such borrowing or issuance that the conditions contained in this
subsection have been satisfied.

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of Section 9(f) above with respect to either Borrower,
automatically the Commitments shall immediately terminate and the Loans
(including the face amount of all Bankers' Acceptances accepted by any Canadian
Revolving Credit Lender), with accrued interest thereon, and all other amounts
owing under this Agreement (including, without limitation, all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) and any Notes
shall immediately become due and payable, and (B) if such event is any other
Event of Default, either or both of the following actions may be taken: (i) with
the consent of the Majority Lenders, the US Administrative Agent and the
Canadian Administrative Agent may, or upon the request of the Majority Lenders,
the US Administrative Agent and the Canadian Administrative Agent shall, by
notice to the Borrowers declare the Commitments to be terminated forthwith,
whereupon the Commitments shall immediately terminate; and (ii) with the consent

                  With respect to all Refunding of Bankers' Acceptances which

to this paragraph, the Canadian Borrower shall at such time deposit in a cash
collateral account opened by Canadian Administrative Agent an amount of cash
equal to the aggregate undiscounted face amount of all unmatured Bankers'
Acceptances. Amounts held in such cash collateral account shall be applied by
the Canadian Administrative Agent to the payment of maturing Bankers'
Acceptances, and the unused portion thereof after all such Bankers' Acceptances
shall have matured, if any, shall be applied to repay other obligations of the
Canadian Borrower hereunder. After all Bankers' Acceptances shall have been
satisfied and all other obligations of the Canadian Borrower hereunder shall
have been paid in full, the balance, if any, in such cash collateral account
shall be returned to the Canadian Borrower.

                  With respect to all Letters of Credit with respect to which
presentment for honor shall not have occurred at the time of an acceleration
pursuant to the preceding paragraph, the Borrower that is the account party in
respect thereof shall at such time deposit in a cash collateral account opened
by the relevant Administrative Agent an amount equal to the aggregate then
undrawn and unexpired amount of such Letters of Credit. Each Borrower hereby
grants to the relevant Administrative Agent, for the benefit of the relevant
Issuing Lender and the relevant L/C Participants, a security interest in such
cash collateral to secure all obligations of such Borrower under this Agreement
and the other Loan Documents. Amounts held in such cash collateral account shall
be applied by the relevant Administrative Agent to the payment of drafts drawn
under such Letters of Credit, and the unused portion thereof after all such
Letters of Credit shall have expired or been fully drawn upon, if any, shall be
applied to repay other Obligations. After all such Letters of Credit shall have
expired or been fully drawn upon, all L/C Reimbursement Obligations shall have
been satisfied and all other Obligations shall have been paid in full, the

                                                                              91




balance, if any, in such cash collateral account shall be returned to the
relevant Borrower. Each Borrower shall execute and deliver to the relevant
Administrative Agent, for the account of the relevant Issuing Lender and the
relevant L/C Participants, such further documents and instruments as such
Administrative Agent may request to evidence the creation and perfection of the
within security interest in such cash collateral account.

                  Except as expressly provided above in this Section,
presentment, demand, protest and all other notices of any kind are hereby
expressly waived.


                       SECTION 10.  THE ADMINISTRATIVE AGENTS

                  10.1 Appointment. (a) Each US$ Lender hereby irrevocably
designates and appoints Canadian Imperial Bank of Commerce, New York Agency, as
the US Administrative Agent of such US$ Lender, and each Canadian Revolving
Credit Lender hereby irrevocably designates and appoints CIBC as the Canadian
Administrative Agent of such Canadian Revolving Credit Lender, under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes Canadian Imperial Bank of Commerce, New York Agency, as the US
Administrative Agent and CIBC, as the Canadian Administrative Agent, for such
Lender, to take such action on its behalf under the provisions of this Agreement
and the other Loan Documents and to exercise such powers and perform such duties
as are expressly delegated to the Administrative Agents by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement, the Administrative Agents shall not have any duties
or responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this

to the Hypothec as security for the due payment of all obligations of the
Canadian Borrower under the Canadian Demand Debenture and the performance by the
Canadian Borrower of all of its obligations contained in the Canadian Demand
Debenture, the Lenders hereby irrevocably grant to the Canadian Administrative
Agent, for the purposes of holding, on behalf and for the benefit of all present
and future Lenders, the security constituted by the Canadian Borrower under the
Hypothec, a power of attorney (within the meaning of the Civil Code of Quebec)
for the present and future Lenders. The Canadian Administrative Agent hereby
accepts such power of attorney for the purposes of holding the security created
under the Hypothec on behalf of and for the benefit of all present and future
Lenders. To the extent that any Person becomes a Lender under this Agreement
after the date hereof, then such Person by becoming bound by the terms and
conditions of this Agreement, whether by assignment or otherwise, shall be
automatically deemed to have ratified the irrevocable granting by the Lenders to
the Canadian Administrative Agent of the power of attorney constituted
hereunder.

                  (c) Notwithstanding the provisions of Section 32 of the
Special Corporate Powers Act (Quebec), the Canadian Administrative Agent may, as
the Person holding the power

whole or in part, any rights to any title to indebtedness issued by the Canadian
Borrower and which is secured by the Hypothec, including without limitation, the
Canadian Demand Debenture.

                  10.2 Delegation of Duties. Each Administrative Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. Neither Administrative
Agent shall be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

                  10.3 Exculpatory Provisions. Neither Administrative Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by any Loan Party
or any officer thereof contained in this Agreement or any other Loan Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by either Administrative Agent under or in connection with,
this Agreement or any other Loan Document or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
the Notes or any other Loan Document or for any failure of any Loan Party to
perform its obligations hereunder or thereunder. Neither Administrative Agent
shall be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Borrower.

                  10.4 Reliance by Administrative Agents. Each Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon
any Note, writing, resolution, notice, consent, certificate, affidavit, letter,
telecopy, telex or teletype message, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to the Company),
independent accountants and other experts selected by either Administrative
Agent. Each Administrative Agent may deem and treat the payee of any Note as the
owner thereof for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Administrative
Agent. Each Administrative Agent shall be fully justified in failing or refusing
to take any action under this Agreement or any other Loan Document unless it
shall first receive such advice or concurrence of the Majority Lenders as it
deems appropriate or it shall first be indemnified to its satisfaction (subject
to provisions in any such indemnification reflecting the exception for gross
negligence or willful misconduct set forth in the proviso in subsection 10.7) by
the Lenders against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action. Each
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the Notes and the other Loan
Documents in accordance with a request of the Majority Lenders, and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all the Lenders and all future holders of the Notes.

                  10.5 Notice of Default. Neither Administrative Agent shall be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless such Administrative Agent has received notice from a
Lender or the Company referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". In the
event that either Administrative Agent receives such a notice, such
Administrative Agent shall give notice thereof to the Lenders. The
Administrative Agents shall take such action with respect to such Default or
Event of Default as shall be reasonably directed by the Majority Lenders;
provided that unless and until the Administrative Agents shall have received
such directions, the Administrative Agents may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as they shall deem advisable in the best interests
of the Lenders.

                  10.6 Non-Reliance on Administrative Agents and Other Lenders.
Each Lender expressly acknowledges that neither Administrative Agent or any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by either
Administrative Agent hereinafter taken, including any review of the affairs of
the Company, shall be deemed to constitute any representation or warranty by
either Administrative Agent to any Lender. Each Lender represents to the
Administrative Agents that it has, independently and without reliance upon
either Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrowers and made its own decision to
make its Loans hereunder and enter into this Agreement. Each Lender also
represents that it will, independently and without reliance upon the
Administrative Agents or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrowers. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Administrative Agents hereunder, neither Administrative Agent
shall have any duty or responsibility to provide any Lender with any credit or
other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of the Borrowers which
may come into the possession of either Administrative Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

                  10.7 Indemnification. The Lenders agree to indemnify each
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrowers and without limiting the obligation of the Borrowers to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought under this subsection (or, if
indemnification is sought after the date upon which the Commitments shall have
terminated and the Obligations shall have been paid in full, ratably in
accordance with their Commitment Percentages immediately prior to such date),
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Notes) be imposed on, incurred by or asserted
against such Administrative Agent in any way relating to or arising out of this
Agreement, any of the other Loan Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by either Administrative Agent under or in
<PAGE>   100
                                                                              94




connection with any of the foregoing; provided that no Lender shall be liable
for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
to the extent resulting from such Administrative Agent's gross negligence or
willful misconduct. The agreements in this subsection shall survive the payment
of the Loans and all other amounts payable hereunder.

                  10.8 Administrative Agents in Their Individual Capacities. The
Administrative Agents and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrowers as though the
Administrative Agents were not the Administrative Agents hereunder and under the
other Loan Documents. With respect to its Loans made or renewed by it and any
Note issued to it and with respect to any Letter of Credit issued or
participated in by it, each Administrative Agent shall have the same rights and
powers under this Agreement and the other Loan Documents as any Lender and may
exercise the same as though it were not an Administrative Agent, and the terms
"Lender" and "Lenders" shall include the Administrative Agents in its individual
capacity.

                  10.9 Successor Administrative Agent. Each Administrative Agent
may resign as Administrative Agent upon 10 days' notice to the Lenders. If
either Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Majority Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor agent
shall be approved by the Company (which approval shall not be unreasonably
withheld), whereupon such successor agent shall succeed to the rights, powers
and duties of such Administrative Agent, and the term "US Administrative Agent"
or "Canadian Administrative Agent", as the case may be, shall mean such
successor agent effective upon such appointment and approval, and the former
Administrative Agent's rights, powers and duties as such Administrative Agent
shall be terminated, without any other or further act or deed on the part of
such former Administrative Agent or any of the parties to this Agreement or any
holders of the Notes. After any retiring Administrative Agent's resignation as
Administrative Agent, the provisions of this subsection shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement and the other Loan Documents.

                  10.10 Releases of Guarantees and Collateral. In connection
with the sale or other disposition of all of the Capital Stock of any Guarantor
or the sale or other disposition of Collateral (as defined in each of the
Security Documents) permitted under subsection 8.6, the Administrative Agents
shall, and are hereby authorized by the Lenders to, promptly, upon the request
of the Borrowers and at the sole expense of the Borrowers, take all actions
reasonably necessary to release such Guarantor from its guarantee contained in
the US Guarantee and Collateral Agreement or its Guarantee or to release the
Collateral subject to such sale or other disposition, as the case may be, and
shall take any other actions reasonably requested by the Borrowers to effect the
transactions permitted under subsection 8.6.


                            SECTION 11. MISCELLANEOUS

                  11.1 Amendments and Waivers. Neither this Agreement, any Note
or any other Loan Document, nor any terms hereof or thereof may be amended,

                                                                              98



the foregoing in this clause (d), collectively, the "indemnified liabilities"),
provided, that the Borrowers shall have no obligation hereunder to either
Administrative Agent or any Lender with respect to indemnified liabilities
arising from (i) the gross negligence or willful misconduct of such
Administrative Agent or any such Lender or (ii) legal proceedings commenced
against such Administrative Agent or any such Lender by any security holder or
creditor thereof arising out of and based upon rights afforded any such security
holder or creditor solely in its capacity as such. The agreements in this
subsection shall survive repayment of the Loans and all other amounts payable
hereunder and, in the case of any Lender that may assign any interest under
subsection 11.6(b), shall survive the making of such assignment, notwithstanding
that such Lender may cease to be a party hereto.

                  11.6 Successors and Assigns; Participations and Assignments.
(a) This Agreement shall be binding upon and inure to the benefit of the
Borrowers, the Lenders, the Administrative Agents, all future holders of any
Notes and their respective successors and assigns, except that the Borrowers may
not assign or transfer any of their rights or obligations under this Agreement
without the prior written consent of each Lender.

                  (b) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time sell to one or more banks or
other entities ("Participants") participating interests in any Loan owing to
such Lender, any Note held by such Lender, any Commitment of such Lender or any
other interest of such Lender hereunder and under the other Loan Documents. In
the event of any such sale by a Lender of a participating interest to a
Participant, such Lender's obligations under this Agreement to the other parties
to this Agreement shall remain unchanged, such Lender shall remain solely
responsible for the performance thereof, such Lender shall remain the holder of
any such Note for all purposes under this Agreement and the other Loan
Documents, and the Borrowers and the Administrative Agents shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement and the other Loan Documents. The
Borrowers agree that if amounts outstanding under this Agreement and any Notes
are due or unpaid, or shall have been declared or shall have become due and
payable upon the occurrence of an Event of Default, each Participant shall be
deemed to have the right of setoff in respect of its participating interest in
amounts owing under this Agreement and any Note to the same extent as if the
amount of its participating interest were owing directly to it as a Lender under
this Agreement or any Note, provided that, in purchasing such participating
interest, such Participant shall be deemed to have agreed to share with the
Lenders the proceeds thereof as provided in subsection 11.7(a) as fully as if it
were a Lender hereunder. The Borrowers also agree that each Participant shall be
entitled to the benefits of subsections 4.10, 4.11 and 4.12 with respect to its
participation in the Commitments and the Loans outstanding from time to time as
if it was a Lender; provided that, in the case of subsection 4.11, such
Participant shall have complied with the requirements of said subsection and
provided, further, that no Participant shall be entitled to receive any greater
amount pursuant to any such subsection than the transferor Lender would have
been entitled to receive in respect of the amount of the participation
transferred by such transferor Lender to such Participant had no such transfer
occurred.

                  (c) Any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time and from time to time assign to
any Lender or any Affiliate thereof or any Approved Fund in respect of such
Lender or, with the consent of the Company (except in the case of assignments
made by CIBC Inc. in connection with its initial syndication of the Loans 
<PAGE>   105
                                                                              99


and Commitments) and the Administrative Agents (which in each case shall not be
unreasonably withheld), to any additional bank or financial institution ("an
Assignee") all or any part of its rights and obligations under this Agreement
and any Notes pursuant to an Assignment and Acceptance, substantially in the
form of Exhibit E, executed by such Assignee, such assigning Lender (and, in the
case of an Assignee that is not then a Lender or an affiliate thereof, by the
Company (except in connection with the initial syndication by CIBC Inc. referred
to above) and the Administrative Agents) and delivered to the Administrative
Agents for acceptance and recording in the relevant Register, provided that the
aggregate amount of Term Loans and Revolving Credit Commitments assigned
pursuant to any such assignment (other than to an Affilate of such Lender or any
Approved Fund in respect of such Lender), and the amount retained by the
assigning Lender (unless such Lender is assigning all of its Loans and
Commitments), must each be in an amount not less than $5,000,000. Upon such
execution, delivery, acceptance and recording, from and after the effective date
determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Commitment as set forth therein, and (y) the assigning Lender thereunder
shall, to the extent provided in such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such assigning Lender shall cease to be a
party hereto, except that it shall remain entitled to the benefit of any
indemnity stated to survive the termination hereof). Notwithstanding any
provision of this paragraph (c) and paragraph (e) of this subsection, the
consent of the Company shall not be required, and, unless requested by the
Assignee and/or the assigning Lender, new Notes shall not be required to be
executed and delivered by either Borrower, for any assignment which occurs at
any time when any of the events described in Section 9(f) shall have occurred
and be continuing. Notwithstanding any provision of this paragraph (c) and
paragraph (e) of this subsection, no Assignment and Acceptance shall be
effective unless and until it shall have been accepted by the applicable
Administrative Agent and recorded in the Register as provided in paragraph (d)
of this subsection.

                  (d) Each Administrative Agent shall, on behalf of the
respective Borrowers, with respect to the Loans relevant to such Administrative
Agent, maintain at its address referred to in subsection 11.2 a copy of each
Assignment and Acceptance delivered to it and a register (the "Register") for
the recordation of the names and addresses of the Lenders and the Commitments
of, and principal amount of the Loans owing to, each relevant Lender from time
to time. The entries in the Registers shall be conclusive, in the absence of
manifest error, and the Borrowers, the Administrative Agents and the Lenders may
(and, in the case of any Loan or other obligation hereunder not evidenced by a
Note, shall) treat each Person whose name is recorded in Registers as the owner
of the Loan recorded therein for all purposes of this Agreement. Any assignment
of any Loan or other obligation hereunder not evidenced by a Note shall be
effective only upon appropriate entries with respect thereto being made in the
relevant Register. The Registers shall be available for inspection by the
relevant Borrower or any Lender at any reasonable time and from time to time
upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an Assignee (and, in the case of an Assignee that is
not then a Lender or an affiliate thereof, by the Company (except in connection
with the initial syndication by CIBC Inc. referred to above) and the
Administrative Agents), together (except as may be waived by the applicable

                                                                             100



Administrative Agent in the case of assignments contemplated to occur
substantially concurrently with the Closing Date) with payment to the relevant
Administrative Agent of a registration and processing fee of $3,500, the
relevant Administrative Agent shall (i) promptly accept such Assignment and
Acceptance and (ii) on the effective date determined pursuant thereto record the
information contained therein in the relevant Register and give notice of such
acceptance and recordation to the Lenders and the Company.

                  (f) Each Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee
subject to the provisions of subsection 11.15, any and all information in such
Lender's possession concerning the Borrowers and their Affiliates which has been
delivered to such Lender by or on behalf of either Borrower pursuant to this
Agreement or which has been delivered to such Lender by or on behalf of either
Borrower in connection with such Lender's credit evaluation of the Borrowers and
their Affiliates prior to becoming a party to this Agreement.

                  (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

                  11.7 Adjustments; Set-off. (a) If any Lender (a "benefitted
Lender") at any time shall receive from either Borrower or any Guarantor any
payment of all or part of any Class of Loans or L/C Reimbursement Obligations,
or interest thereon, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of
the nature referred to in Section 9(f) or otherwise), in a greater proportion
than any such payment to or collateral received by any other Lender, if any, in
respect of such other Lender's Loans or L/C Reimbursement Obligations of such
Class, or interest thereon, such benefitted Lender shall purchase for cash from
the other Lenders which hold Loans or L/C Reimbursement Obligations of such
Class such portion of each such other Lender's Loans or L/C Reimbursement
Obligations of such Class, or shall provide such other Lenders with the benefits
of any such collateral, or the proceeds thereof, as shall be necessary to cause
such benefitted Lender to share the excess payment or benefits of such
collateral or proceeds ratably with each of such other Lenders; provided,
however, that if, at the time of the receipt by the benefitted Lender of such
payment or collateral, amounts shall be then due and unpaid in respect of more
than one Class, the sharing described in this subsection shall include all
Classes with respect to which amounts are then due and unpaid (provided that in
no event shall any such sharing which shall occur prior to the date upon which
the Loans shall have become due and payable (whether at the stated maturity, by
acceleration or otherwise) be effected (i) among Classes in respect of which the
obligors are not the same Borrower, (ii) by the Canadian Term Loan Lenders with
any other Class in respect of which the obligor is the Canadian Borrower or
(iii) which would result in any Canadian Term Loan Lender receiving amounts in
excess of the limits imposed by subsection 4.3(f)(iii)); and provided, further,
that if all or any portion of such excess payment or benefits is thereafter
recovered from such benefited Lender, such purchase shall be rescinded, and the
purchase price and benefits returned, to the extent of such recovery, but
without interest. Each Borrower agrees that each Lender so purchasing a portion
of another Lender's Loan may exercise all rights of payment (including, without
limitation, rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

                                                                             101



                  (b) If, as a result of the operation of the second sentence of
subsection 2.16(b)(7), any Canadian Revolving Credit Lender shall, on any date
upon which all the Loans shall be accelerated in accordance with the last
paragraph of Section 9, be the issuer Bankers' Acceptances in an aggregate
amount which is less than such Canadian Revolving Credit Lender's Canadian
Revolving Credit Commitment Percentage of the aggregate amount of all the then
outstanding Bankers' Acceptances, such Canadian Revolving Credit Lender shall
purchase for cash from each of the other Canadian Revolving Credit Lenders such
portion of each such other Canadian Revolving Credit Lender's obligations with
respect to then outstanding Bankers' Acceptances as shall be necessary to cause
all such obligations with respect to Bankers' Acceptances to be held ratably
among the Canadian Revolving Credit Lenders according to their respective
Canadian Revolving Credit Commitment Percentages. The Canadian Borrower agrees
that each Canadian Revolving Credit Lender so purchasing a portion of another
Canadian Revolving Credit Lender's obligations with respect to Bankers'
Acceptances may exercise all rights of payment (including, without limitation,
rights of set-off) with respect to such portion as fully as if such Lender were
the direct holder of such portion.

                  (c) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to
either Borrower, any such notice being expressly waived by each Borrower to the
extent permitted by applicable law, upon any amount becoming due and payable by
either Borrower hereunder or under any Notes (whether at the stated maturity, by
acceleration or otherwise) to set-off and appropriate and apply against such
amount any and all deposits (general or special, time or demand, provisional or
final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect, absolute or contingent,
matured or unmatured, at any time held or owing by such Lender or any branch or
agency thereof to or for the credit or the account of such Borrower. Each Lender
agrees promptly to notify the Company and the US Administrative Agent after any
such set-off and application made by such Lender, provided that the failure to
give such notice shall not affect the validity of such set-off and application.

                  11.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by telecopy), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Agreement signed by all the parties shall be lodged with the Company and the US
Administrative Agent.

                  11.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                  11.10 Integration. This Agreement and the other Loan Documents
represent the agreement of the Borrowers, the Administrative Agents and the
Lenders with respect to the subject matter hereof, and there are no promises,
undertakings, representations or warranties by either Administrative Agent or
any Lender relative to subject matter hereof not expressly set forth or referred
to herein or in the other Loan Documents.

                  11.12 Submission To Jurisdiction; Waivers. Each Borrower
hereby irrevocably and unconditionally:

                  (a) submits for itself and its property in any legal action or
         proceeding relating to this Agreement and the other Loan Documents to
         which it is a party, or for recognition and enforcement of any
         judgement in respect thereof, to the non-exclusive general jurisdiction

         of America for the Southern District of New York, and appellate courts
         from any thereof;

                  (b) consents that any such action or proceeding may be brought
         in such courts and waives any objection that it may now or hereafter
         have to the venue of any such action or proceeding in any such court or
         that such action or proceeding was brought in an inconvenient court and
         agrees not to plead or claim the same;

                  (c) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to such Borrower at its address set forth in subsection 11.2
         or at such other address of which the Administrative Agents shall have
         been notified pursuant thereto;

                  (d) agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                  (e) waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this subsection any special, exemplary, punitive or
         consequential damages.

                  11.13  Acknowledgements.  Each Borrower hereby acknowledges 
         that:

                  (a) it has been advised by counsel in the negotiation,
         execution and delivery of this Agreement, the Notes and the other Loan

         fiduciary relationship with or duty to such Borrower arising out of or
         in connection with this Agreement or any of the other Loan Documents,
         and the relationship between Administrative Agent and Lenders, on one
         hand, and such Borrower, on the other hand, in connection herewith or
         therewith is solely that of debtor and creditor; and

                  (c) no joint venture is created hereby or by the other Loan

         contemplated hereby among the Lenders or among the Borrowers and the
         Lenders.
