ITEM 1.  BUSINESS.
- ------   ---------

General

     Pierce Leahy Corp. ("the Company") is the largest hard copy records
management company in North America, as measured by its approximately 64 million
cubic feet of records under management as of March 1, 1998.  The Company
operates a total of 188 records management facilities of which 171 are in the
United States and 17 are in Canada.

     The Company is a full-service provider of records management and related
services, enabling customers to outsource their data and records management
functions.  The Company offers storage for all major media, including paper
(which has typically accounted for over 90% of the Company's storage revenues),
computer tapes, optical discs, microfilm, video tapes and X-rays.  In addition,
the Company provides next day or same day records retrieval and delivery,
allowing customers prompt access to all stored material.  The Company also
offers other data management services, including customer records management
programs, imaging services and records management consulting services.

     The Company serves a diversified group of over 30,000 customer accounts in
a variety of industries such as financial services, manufacturing,
transportation, healthcare and law.  The Company's storage and related services
are typically provided pursuant to contracts that include recurring monthly
storage fees, which continue until such records are permanently removed (for
which the Company charges a fee), and additional charges for services such as
retrieval on a per unit basis.

     Saved documents, or records, generally fall into two categories:  active
and inactive.  Active records refer to information that is frequently referenced
and usually stored on-site by the originator.  Inactive records are not needed
for frequent access, but must be retained for future reference, legal
requirements or regulatory compliance.  Inactive records are the principal focus
of the records management industry.

ACQUISITION HISTORY AND GROWTH STRATEGY

     The Company expects that acquisitions will remain an important part of its
growth strategy.  During 1997, the Company completed and integrated 17
acquisitions, totaling approximately 10.3 million cubic feet of records at the
time of acquisition.  Since January 1, 1998, the Company has completed five
acquisitions, totaling approximately 3.9 million cubic feet of records at the
time of acquisition.  In addition, the Company has signed a definitive agreement
to purchase Archivex Inc., a regional records management company in Canada, for
Cdn. $90.0 million, which it intends to finance through borrowings under its
credit facility or issuance of additional debt securities.  The acquisition is
subject to customary conditions and is expected to close in April 1998.

</TABLE>

DESCRIPTION OF SERVICES

  The Company's records management services are focused on storage, retrieval
and data management of hard copy documents.

Storage

  Storage revenues were 59% of total revenues during 1997.  Nearly all of the
Company's storage fees are derived from hard copy storage.  During 1997, the
Company generated 94% of its storage revenues from hard copy storage and 6% from
vault storage for special items such as computer tapes, X-rays, films or other
valuable items.  Storage charges typically are billed monthly on a per cubic
foot basis.

  The Company tracks all of its records stored in cartons, from initial pick-up
through permanent removal, with the use of its Pierce Leahy User Solution(R)
(PLUS(R)) computer system.  Bar-coded boxes are packed by the customer and
transported by the Company's transportation department to the appropriate
facility where they are scanned and placed into storage at the locations
designated by PLUS(R).  At such time, the Company's data input personnel enter
the data twice (i.e., double key verifying) to enhance the integrity of the
information entered into the system.

  The Company offers secure, climate-controlled facilities for the storage of
non-paper forms of media such as computer tapes, optical discs, microfilm, video
tapes and X-rays.  These types of media often require special facilities due to
the nature of the records.  The Company's storage fees for non-paper media, are
higher than for typical paper storage.  The Company also provides ancillary
services for non-paper records in the same manner as it provides for its hard
copy storage operations.

Service and Storage Material Sales

  The Company's principal services include adding records to storage, temporary
removal of records from storage to support a customer's need to review the
files, replacing temporarily removed records and permanent withdrawals from
storage or destruction of records. Pick-up and delivery of customer records can
be tailored to a customer's specific needs and range from standard service
(typically requests received 

                                       3
<PAGE>
 
by 10:30 a.m. are delivered or picked up that afternoon and requests received by
3:30 p.m. are delivered or picked up the next day) to emergency service
(typically within three hours or less). Pick-up and delivery operations are
supported by the Company's fleet of over 500 owned or leased vehicles. The
Company charges for pick-up and delivery services on a per-unit basis depending
on the immediacy of delivery requested.

  A small percentage of the Company's customers manage their records on a file
by file basis, allowing the customer direct access and traceability of a
specific file (rather than on a box by box basis).  The Company provides data
entry services to such customers to input the file by file listings into the
PLUS(R) system.

  The Company also offers a records destruction service, which provides
customers with a secure, controlled program to periodically review and remove
records which no longer need to be retained.  Although boxes destroyed no longer
generate monthly storage fees, the Company charges for the destruction of
records and increases its available shelving space as a result.

  In addition to providing traditional storage, customers may contract with the
Company to manage their on-site records or file services center.  Such
management services generally include providing Company personnel to manage the
customer's active files (including records storage and tracking) at the
customer's facilities, supplemented by off-site storage at the Company's
facilities.  As part of this service, the Company can use its own internally
developed file management software, or maintain the customer's existing system.
The Company also provides consulting and other services on an individualized
basis, including advisory work for customers setting up in-house records
management systems.  In addition, the Company sells cardboard boxes and other
storage containers to its customers.

CUSTOMER SERVICE

  Customer calls are routed into one of the Company's two centralized customer
service departments located in the Company's U.S. and Canadian corporate
headquarters.  Both customer service departments are staffed and can receive
customer calls 24 hours a day, seven days a week.  Routine pick-up and delivery
requests are dispatched directly by customer service representatives to local
facilities as directed by PLUS(R).

  As a complement to its centralized customer service departments, the Company
provides client service representatives to work with existing customers at the
local level.  In addition to maintaining personal contacts with customers, the
local client service representatives help meet the Company's customers' changing
records management needs through advice in efficient record keeping procedures,
and, when appropriate, by offering the sale of additional services.

MANAGEMENT INFORMATION SYSTEMS

  The Company believes that PLUS(R), its core management information system, is
the most sophisticated records management system in the industry, and provides
the Company with a significant customer service and cost advantage in attracting
and retaining major accounts with records storage needs in multiple locations
and acquiring other records management companies.  The Company's centralized
customer service and billing functions eliminate the need for redundant
functions at individual facilities.  In addition, the PLUS(R) system enables the
Company to offer its customers full life cycle records management, from file
creation to destruction, and coordinates inventory control, order entry,
billing, material sales, service activity, accounts receivable and management
reporting on a centralized basis.  PLUS(R) utilizes database technology,
proprietary software and extensive bar coding in a flexible, enterprise-wide,
client/server environment.

  PLUS(R) offers several additional features which enhance the Company's
customer support functions. The system is continuously updated when any account
activity is undertaken, providing customers with real time access to information
regarding box location and retrievals.  The PLUS(R) system is flexible and
allows the Company to design and implement customized records management
solutions for various industries 

                                       4
<PAGE>
 
utilizing a set of standardized options. The PLUS(R) system's on-line customer
support network allows certain customers to place orders for both records
storage and retrieval directly from their own in-house terminals resulting in a
more efficient system of records management.

SALES AND MARKETING

  During the past five years, the Company has invested significant effort in
developing its sales and marketing department, which is currently comprised of
approximately 110 employees in the United States and Canada.  Sales
representatives are trained to sell a "total systems approach," in which a
customer's records management requirements are surveyed and evaluated in order
to determine the file management system which best meets the customer's needs
and offer recommendations on how to implement such a system.

  The Company's sales and marketing department is divided into five regions:
Northeast; South; Midwest; West; and Canada.  The Company's Vice President,
Sales and Marketing directs five regional sales managers.  In addition, the
Company's sales force is divided between sales representatives who focus on
large accounts which are frequently multi-location and a recently expanded group
of sales representatives who focus on smaller, single-location customers.  The
sales force is primarily compensated on a commission basis with incentives tied
to the Company's sales goals.  The Company also uses telemarketing, direct
response and print advertising to assist in its marketing programs.

CUSTOMERS

  The Company serves a diversified group of over 30,000 customer accounts in a
variety of industries, including financial services, manufacturing,
transportation, healthcare and law.  The Company tracks customer accounts, which
are based on invoices.  Accordingly, depending on how invoices have been
arranged at the request of a customer, one customer may have multiple customer
accounts.  None of the Company's customers accounted for more than 3% of the
Company's total revenues during 1997.  The Company services all types of
customers from small to medium size companies (such as professional groups and
law firms that often have one location) to Fortune 500 companies that have
operations in multiple locations.

  The Company's contracts with larger, typically multi-location customers
usually provide for an initial term of five or more years, and contracts with
other customers typically provide for initial terms of one or two years.  Both
types of contracts generally provide for annual renewals thereafter (with either
party having the right to terminate the contract).  Customers are generally
charged monthly storage fees until their records are destroyed or permanently
removed, for which fees are charged.

COMPETITION

  The Company competes with numerous records management companies in all
geographic areas in which it operates.  The Company believes that competition
for customers is based on price, reputation for reliability, quality of service
and scope and scale of technology, and believes that it generally competes
effectively based on these factors.  Management believes that, except for Iron
Mountain Incorporated, all of these competitors have records management revenues
significantly lower than those of the Company.  The Company believes that the
trend towards consolidation in the industry will continue and the Company also
faces competition in identifying attractive acquisition candidates.  In
addition, the Company faces competition from the internal document handling
capability of its current and potential customers.

  The substantial majority of the Company's revenues are derived from the
storage of paper records and from related services.  Alternative technologies
for generating, capturing, managing, transmitting and storing information have
been developed, many of which require significantly less space than paper.  Such
technologies include computer media, microforms, audio/video tape, film, CD-ROM
and optical disc. Management believes that conversion of paper documents into
these smaller storage media is currently not cost effective for inactive
records, primarily due to the high labor cost of preparing the documents for

                                       5
<PAGE>
 
imaging, indexing the images for subsequent retrieval, and ensuring that all the
documents were imaged legibly.

EMPLOYEES

  As of December 31, 1997, the Company had 2,295 employees, including 260
employees in Canada. None of the Company's employees are covered by a collective
bargaining agreement.  Management considers its employee relations to be good.

INSURANCE

  The Company carries comprehensive property insurance covering replacement
costs of real and personal property.  Subject to certain limitations and
deductibles, such policies also cover extraordinary expenses associated with
business interruption and damage or loss from fire, flood or earthquakes (in
certain geographic areas), and losses at the Company's facilities up to
approximately $400 million.

ENVIRONMENTAL MATTERS

  The Company's properties and operations may be subject to liability under
various environmental laws, regardless of fault, for the investigation, removal
or remediation of soil or groundwater, on or off-site, resulting from the
release or threatened release of hazardous materials, as well as damages to
natural resources.  The owner or operator of contaminated property may also be
subject to claims for damages and remediation costs from third parties based
upon the migration of any hazardous materials to other properties.

  At certain of the properties owned or leased by the Company, petroleum
products or other hazardous materials are or were stored in underground storage
tanks ("USTs"). Some formerly used USTs have been removed; others were abandoned
in place.  The Company believes all of the USTs are registered, where required
under applicable law.  The Company also is aware of the presence in some of its
facilities of asbestos-containing materials, but believes that no action is
presently required to be taken as a result of such material.

  At the Company's New Jersey facility, certain contamination has been
discovered resulting from operations of the prior owner thereof.  The prior
owner, which has agreed to be responsible for the cost of such remediation, is
completing remediation of the property under a consent order with the New Jersey
Department of Environmental Protection ("NJDEP").  The prior owner has posted a
$1.1 million letter of credit with the NJDEP.  The Company has purchased an
environmental liability insurance policy covering the cleanup costs to the
Company, if any, resulting from any on- or off-site environmental condition
existing at the time of the Company's acquisition of this property, with a
$250,000 deductible and policy limits of $4 million per occurrence/$8 million in
the aggregate, provided the claim first arises during the term of the policy,
which is August 10, 1995 through August 11, 1998.

  The Company has not received any written notice from any governmental
authority or third party asserting, and is not otherwise aware of, any material
noncompliance, liability or claim under environmental laws applicable to the
Company other than as described above.  No assurance can be given that there are
no environmental conditions for which the Company may be liable in the future or
that future regulatory action, or compliance with future environmental laws,
will not require the Company to incur costs that could have a material adverse
effect on the Company's financial condition or results of operations.

Item 3. LEGAL PROCEEDINGS.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
- -------   -----------------------------------------------------------
          AND RESULTS OF OPERATIONS.
          --------------------------

GENERAL

The Company is the largest hard copy records management company in North
America, as measured by its 64.0 million cubic feet of records currently under
management.  The Company's operations date to 1957 when its predecessor company,
L.W. Pierce Co., Inc., was founded to provide filing systems and related
equipment to companies in the Philadelphia area.  The Company expanded primarily
through internal growth until 1990, when it acquired Leahy Business Archives,
which effectively doubled its size.  Since 1992, the Company has pursued an
expansion strategy combining growth from new and existing customers with the
completion and successful integration of 43 acquisitions through 1997 and the
completion of three acquisitions in January 1998, one in February 1998, and one
March 1998.

The Company's income (loss) was $(15.2) million, $.5 million and $2.1 million in
1997, 1996, and 1995, respectively.  Although the Company's operating income has
increased over the three years, net income (loss) has fluctuated as a result of
increases in interest expense, income taxes related to the termination of the
Company's status as a Subchapter S corporation, and extraordinary charges
related to the early extinguishment of debt due to refinancings in 1997, 1996
and 1995.

Another tool for measuring the performance of records management companies is
EBITDA.  Substantially all of the Company's financing agreements, including its
11.125% Senior Subordinated Notes due 2006 ("1996 Notes") and its 9.125% Senior
Subordinated Notes due 2007 ("1997 Notes"; together, the "Notes"), contain
covenants in which EBITDA is used as a measure of financial performance.
However, EBITDA should not be considered an alternative to operating or net
income (as determined in accordance with generally accepted accounting
principles ("GAAP")), as an indicator of the Company's performance or to cash

     (a)Net of permanent removals.  Includes effect of records destruction
program of 475 and 372 cubic feet of records in 1996 and 1995, respectively, for
a major customer, as recommended by the Company pursuant to a consulting
agreement with the Company.


Revenues

The Company's revenues consist of storage revenues (58.8% of total revenues in
1997), and related service and storage material sales revenues (41.2% of total
revenues in 1997).  The Company provides records storage and related services
under annual or multi-year contracts that typically provide for recurring
monthly storage fees which continue until such records are permanently removed
(for which the Company charges a service fee) and service charges based on
activity with respect to such records.

While the Company's total revenues have increased from 1995 to 1997, total
revenue per annual average cubic foot during such period has declined.  The
decline is principally attributable to (i) increases in sales to large volume
accounts under long-term contracts with discounted rates, which generate lower
revenue per cubic foot, but typically generate increased operating income, (ii)
renegotiation of contracts with existing customers to provide for longer term
contracts at lower rates, and (iii) competition.

Operating Expenses and Productivity

Operating expenses consist primarily of cost of sales, selling, general and
administrative expenses, and depreciation and amortization.  Cost of sales are
comprised mainly of wages and benefits, facility occupancy costs, equipment
costs and supplies.  The major components of selling, general and administrative
expenses are management, administrative, marketing and data processing wages and
benefits and also include travel, communication and data processing expenses,
professional fees and office expenses.

The Company's depreciation and amortization charges result primarily from the
capital-intensive nature of its business and the completed acquisitions.  The
principal components of depreciation relate to shelving, facilities and
leasehold improvements, equipment for new facilities and computer systems.
Amortization primarily relates to the amortization of intangible assets
associated with acquisitions, including goodwill, and the amortization of client
acquisition costs.  The Company has accounted for all of its acquisitions under
the purchase method except for two small acquisitions, which were accounted for
under the pooling 

                                       12
<PAGE>
 
of interests method. Since the purchase price for records management companies
is usually substantially in excess of the fair market value of their assets,
these purchases have given rise to significant goodwill and, accordingly,
significant levels of amortization. Although amortization is a non-cash charge,
it does impact reported net income (loss).

Capital Expenditures and Client Acquisition Costs

The majority of the Company's capital expenditures are related to expansion.
The largest single component is the purchase of shelving, which is directly
related to the addition of new records.  Shelving has a relatively long life and
rarely needs to be replaced.  Most of the Company's storage facilities (both in
number and square feet) are leased, but the Company will purchase facilities on
an opportunistic basis.  The Company's data processing capital expenditures are
also largely related to growth.

The Company often incurs client acquisition costs, primarily sales commissions
and move-in costs.  Client acquisition costs are capitalized and amortized over
six years, which is the average initial contract term of new customer accounts.
In 1997, the Company incurred $10.6 million of client acquisition costs or
approximately $2.04 per cubic foot of client records moved in from new clients.
Amortization of client acquisition costs amounted to $3.2 million in 1997.

Extraordinary Charge

To provide capital to fund its growth oriented business strategy, the Company
has incurred substantial indebtedness.  The Company has completed several
expansions of its credit facilities, primarily utilizing bank debt, which have
resulted in one-time charges, including the repurchase of warrants and the
write-off of deferred financing costs, of $6.0 million, $2.0 million and $3.3
million in 1997, 1996 and 1995, respectively.


Year 2000 Compliance

The Company has developed a plan designed to make its systems compliant with the
requirements to process transactions in the year 2000.  Review of the Company's
core PLUS system databases and programs has been completed and code
modifications and testing are scheduled to be completed by December 31, 1998.
The present version of the Company's internal financial accounting system is not
year 2000 compliant and is scheduled to be upgraded by December 31, 1998.  The
Company is also working with its other internal information systems and network
providers to ensure all systems are year 2000 compliant.  The Company estimates
that the expenses and capital expenditures associated with achieving year 2000
compliance will not have a material effect on its financial results in 1998 or
1999.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

Total revenues increased from $129.7 million in 1996 to $183.5 million in 1997,
an increase of $53.8 million or 41.4%.  Revenues from acquisitions represented
$34.9 million of this increase. Approximately $18.9 million of the total revenue
growth resulted from sales to new customers and increases in cubic feet stored
from existing customers, a base business revenue growth of approximately 16%
year over year.

Storage revenues increased from $75.9 million in 1996 to $107.9 million in 1997,
an increase of $32.0 million or 42.1%.  Service and storage material sales
revenues increased from $53.8 million in 1996 to $75.6 million in 1997, an
increase of $21.8 million or 40.5%.

Cost of sales (excluding depreciation and amortization) increased from $73.9
million in 1996 to $101.9 million in 1997, an increase of $28.1 million or
38.0%, but decreased slightly as a percentage of total revenues from 57.0% in
1996 to 55.5% in 1997.  The $28.1 million increase was due primarily to
increases in wages and benefits resulting from an increased number of employees
and to increases in facility occupancy costs resulting from an increase in cubic
feet associated with the growth in business and entry into 14 new markets during
1997.  Capacity utilization is generally lower in new markets than in existing
markets.  The decrease as a percentage of total revenue was due primarily to
increased labor operating efficiencies.

Selling, general and administrative expenses increased from $20.0 million in
1996 to $30.1 million in 1997, an increase of $10.1 million or 50.3%, and
increased as a percentage of total revenues from 15.4% in 1996 to 16.4% in 1997.
The increase as a percentage of total revenues was due to increases in sales
personnel and training costs associated with the increased staff, enhancements
to the PLUS(R) computer system, and temporarily carrying duplicate
administrative costs from recent acquisitions.

A special compensation charge of $1.8 million was incurred during 1997.  This
charge relates to the write-off of the unamortized compensation expense due to
the acceleration of the vesting of the stock options granted on January 1, 1997
in conjunction with the Company's initial public offering of Common Stock.

Depreciation and amortization expenses increased from $12.9 million in 1996 to
$21.5 million in 1997, an increase of $8.7 million or 67.3%, and increased as a
percentage of total revenues from 9.9% in 1996 to 11.7% in 1997.  This increase
was the result of increased capital expenditures for shelving, building, and
improvements to records management facilities and information systems and the
amortization of goodwill from the Company's acquisitions and client acquisition
costs.

The Company incurred a foreign currency exchange adjustment during 1997 of $0.7
million during which time the Company had an intercompany loan with its Canadian
subsidiary.  This exchange adjustment was directly related to the decrease in
the Canadian dollar to U.S. dollar exchange rate during the last quarter of
1997.

The Company incurred non-recurring charges of $3.3 million, or 2.5% of total
revenues, in 1996 in connection with the assumption of leasehold interests in
certain facilities from affiliated parties completed in connection with the sale
of the 1996 Notes and with the establishment of a pension for Leo W. Pierce, Sr.

Interest expense increased from $17.2 million in 1996 to $29.3 million in 1997,
an increase of $12.0 million or 69.9%.  The increase was primarily attributable
to increased indebtedness related to financing acquisitions and capital
expenditures, as well as the higher interest rate on the 1997 Notes issued in
July 1997 and a full year of interest expense on the 1996 Notes compared to the
bank debt repaid upon the issuance of the 1997 Notes and 1996 Notes.  Interest
expense was also affected by the proceeds of the Company's initial public stock
offering.

                                       15
<PAGE>
 
As a result of the foregoing factors, the Company had a loss before income taxes
and extraordinary charge of $1.7 million (0.9% of revenues) for 1997 compared to
income of $2.5 million (1.9% of revenues) in 1996.

The Company recorded a provision for income taxes of $7.4 million (or 4.1% of
revenues) for 1997.  These taxes were comprised of the tax effect from the
termination of the Company's Subchapter S corporation status ($6.6 million) and
the provision for the results of operations after the termination of its status
as a S corporation on July 1, 1997 ($0.8 million).  There was no provision for
income taxes in the year ended 1996 since the Company operated as a Subchapter S
corporation during the period.

The Company recorded extraordinary charges of $6.0 million in 1997 and $2.0
million in 1996 related to the early extinguishment of debt as a result of
refinancing and expanding its existing credit agreement in 1997 and 1996.

As a result of the foregoing items, the Company had a net loss of $15.2 million
and net income of $0.5 million for 1997 and 1996, respectively.

EBITDA increased from $35.9 million in 1996 to $51.5 million in 1997, an
increase of $15.6 million or 43.6%, and increased as a percentage of total
revenues from 27.6% in 1996 to 28.1% in 1997.  The increase as a percentage of
the total revenues reflected growth in the Company's business, economies of
scale and increased operating efficiencies.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

Total revenues increased from $95.4 million in 1995 to $129.7 million in 1996,
an increase of $34.3 million or 36.0%.  Revenues from acquisitions represented
$25.7 million or 74.9% of this increase, including $16.3 million from a full
year of operations of five acquisitions made in 1995 and $9.4 million from a
partial year of operations of twelve acquisitions made in 1996.  Approximately
$8.6 million or 25.1% of the total revenue growth resulted from sales to new
customers and increases in cubic feet stored from existing customers.

Storage revenues increased from $55.5 million in 1995 to $75.9 million in 1996,
an increase of $20.4 million or 36.8%.  Service and storage material sales
revenues increased from $39.9 million in 1995 to $53.8 million in 1996, an
increase of $13.9 million or 35.0%.

Cost of sales (excluding depreciation and amortization) increased from $55.6
million in 1995 to $73.9 million in 1996, an increase of $18.3 million or 32.8%,
but decreased as a percentage of total revenues from 58.3% in 1995 to 57.0% in
1996.  The $18.3 million increase was due primarily to increases in wages and
benefits resulting from an increased number of employees and increases in
facility occupancy costs associated with the growth in business.  The decrease
as a percentage of total revenue was due primarily to increased operating and
storage efficiencies.

Selling, general and administrative expenses increased from $16.1 million in
1995 to $20.0 million in 1996, an increase of $3.9 million or 23.9%, and
decreased as a percentage of total revenues from 16.9% in 1995 to 15.4% in 1996.
The decrease as a percentage of total revenues was due to operating efficiencies
and the implementation of programs to control and reduce certain administrative
expenses.  The purchase of certain real estate interests from affiliates in
August 1996 contributed $0.9 million to the reduction in cost of sales or 0.7%
as a percentage of revenues.

Depreciation and amortization expenses increased from $8.2 million in 1995 to
$12.9 million in 1996, an increase of $4.7 million or 57.7%, and increased as a
percentage of total revenues from 8.6% in 1995 to 9.9% in 1996.  This increase
was the result of increased capital expenditures for shelving and improvements
to record management facilities and information systems and the amortization of
goodwill from the Company's acquisitions.

                                       16
<PAGE>
 
The Company incurred non-recurring charges of $3.3 million in 1996 in connection
with the assumption of leasehold interests in certain facilities from affiliated
parties and with the establishment of a pension for Leo W. Pierce, Sr.

As a result of the foregoing factors, excluding the non-recurring charges in
1996, operating income increased from $15.0 million in 1995 to $23.0 million in
1996, an increase of 53.7%, and increased as a percentage of total revenues from
15.7% in 1995 to 17.7% in 1996.  The increase reflected the growth in the
Company's business, economies of scale and increased operating efficiencies.

Interest expense increased from $9.6 million in 1995 to $17.2 million in 1996,
an increase of $7.6 million or 79.0%, due primarily to higher levels of
indebtedness.  The Company recorded extraordinary charges of $2.0 million in
1996 and $3.3 million in 1995 related to the early extinguishment of debt as a
result of refinancing and expanding its existing credit agreement in 1996 and
1995.

As a result of the foregoing factors, net income was $0.5 million in 1996
compared to net income of $2.1 million in 1995.

EBITDA increased from $23.6 million in 1995 to $35.9 million in 1996, an
increase of $12.3 million or 51.8%, and increased as a percentage of total
revenues from 24.8% in 1995 to 27.7% in 1996.  The increase as a percentage of
the total revenues reflected growth in the Company's business, economies of
scale and increased operating efficiencies.

LIQUIDITY AND CAPITAL RESOURCES

The Company's primary sources of capital have been cash flows from operations
and borrowings under various revolving credit facilities and other senior
indebtedness.  Historically, the Company's primary uses of capital have been for
acquisitions, capital expenditures and client acquisition costs.

Capital Investments

For 1997, 1996 and 1995, capital expenditures were $35.4 million, $23.5 million
and $16.3 million, respectively, and client acquisition costs were $10.6
million, $6.5 million and $2.2 million, respectively.  In 1998, the Company
expects its aggregate capital expenditures will approximate $35.0 million.  Over
85% of 1998 capital expenditures are anticipated to be growth related, primarily
shelving for new client records.

Acquisitions

In order to take advantage of the operating efficiencies of the PLUS(R) computer
system and the opportunities presented by the consolidation undergoing in the
record management industry, the Company has actively pursued acquisitions since
the beginning of 1994, which has significantly impacted liquidity and capital
resources.  In 1997, the Company completed 17 acquisitions for an aggregate
purchase price of $109.1 million, consisting of $102.1 million in cash, 328,621
shares of Common stock with a deemed value of $4.5 million and $1.7 million in
Sellers notes.  Since the beginning of 1998, the Company has completed five
acquisitions for an aggregate cash purchase price of approximately $41.7
million.  In addition, the Company has signed a definitive agreement to purchase
a regional records management company for approximately CDN $90.0 million, which
it intends to finance through the issuance of additional debt securities.  The
acquisition is subject to due diligence and other customary conditions.  The
Company has historically financed its acquisitions with borrowings under its
credit agreements and with cash flows from existing operating activities.
During 1996, the Company also issued $200 million principal amount of 1996
Notes, a small portion of which was used to fund acquisitions.  Funding for 1997
acquisitions was primarily from borrowings under its credit agreements.

The Company believes that future cash flows from operations, together with
borrowings under the Credit Facility, will be sufficient to fund future working
capital needs, capital expenditure requirements and debt service requirements of
the Company for the foreseeable future.

To the extent that future acquisitions are financed by additional borrowings
under the Company's credit facility or other types of indebtedness, the
resulting increase in debt and interest expense could have a negative effect on
such measures of liquidity as debt to equity.

Sources of Funds

Net cash flows provided by operating activities were $21.0 million, $26.4
million and $17.5 million for 1997, 1996 and 1995, respectively.  The $5.5
million decrease from 1996 to 1997 was primarily comprised of a reduction in net
income of $15.7 million and a $14.1 million increase in working capital, offset
by a $9.2 million increase in depreciation and amortization, an increase in
deferred income taxes of $7.4 million, a $4.0 million increase in extraordinary
charge and a special compensation charge of $1.8 million in 1997.

Net cash flows used in investing activities were $156.5 million, $108.8 million
and $51.3 million for 1997, 1996 and 1995, respectively.  The uses of such cash
flows were primarily for acquisitions, capital expenditures and client
acquisition expenditures detailed above.

Net cash flows provided by financing activities were $136.1 million, $82.9
million and $34.2 million for 1997, 1996, and 1995, respectively.  In 1997, the
$136.1 million in financing activities consisted primarily of $120 million of
gross proceeds from the issuance of the 1997 Notes, $93.6 million in net
proceeds from the Company's initial public offering of Common Stock, and $17.2
million of borrowings on the revolving line of credit, offset by the repayment
of long-term debt of $82.5 million and the $7.0 million prepayment premium on
the redemption of a portion of the 1996 Notes and the payment of $5.2 million of
financing costs related to the issuance of the 1997 Notes and the Company's
credit facility.  In August 1997, the Company entered into its current Credit
Facility, which provides $140 million in U.S. dollar borrowings, and CDN $35
million in Canadian dollar borrowings.  The credit facility was amended in
February 1998 to provide for borrowings of U.S. $150 million and CDN $40
million.  In July 1996, the Company issued $200 million of the 1996 Notes and
used the net proceeds to retire all of the debt outstanding under the Company's
previous credit facility, to purchase certain properties from affiliates of the
Company, to redeem stock from a shareholder of the Company, to fund an
acquisition and for general corporate purposes.

The Credit Facility contains a number of financial and other covenants
restricting the Company's ability to incur additional indebtedness and make
certain types of expenditures.  Covenants in the indentures governing the Notes
also restrict borrowings under the Credit Facility.  As of December 31, 1997,
CDN $31.9 million was outstanding under the Credit Facility and the Company
could have borrowed an additional $64.0 million under the Credit Facility in
accordance with the debt incurrence limitations.  Additionally, to the extent
the Company makes acquisitions, it would have additional availability under the
Credit Facility based upon the pro forma EBITDA of such acquisitions.  The
effective interest rate on the Credit Facility, as of December 31, 1997, was
approximately 6.38%.

Future Capital Needs

Management believes that cash flow from operations in conjunction with
borrowings under the Credit Facility and possible other sources of financing
will be sufficient for the foreseeable future to meet working capital
requirements and to make possible future acquisitions and capital expenditures.
Depending on the pace and size of future possible acquisitions, the Company may
elect to seek additional debt or equity financing.  There can be no assurance
that the Company will be able to obtain any future financing, if required, or
that the terms for any such future financing would be favorable to the Company.

Company's management.  Our responsibility is to express an opinion on these

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 Pierce Leahy Corp. and

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               DECEMBER 31, 1997
                 (IN THOUSANDS EXCEPT SHARE AND PER SHARE DATA)



1.   BACKGROUND:
     ---------- 

Pierce Leahy Corp., (the "Company"), stores and services business records for
clients throughout the United States and Canada.  The Company also sells storage
containers and provides records management consulting services and imaging
services.

On June 25, 1997, the Company effected a stock split, reclassified its Class A
and Class B Common stock to Common stock, authorized 10,000,000 shares of
undesignated Preferred stock and increased its authorized Common stock to
80,000,000 shares.  All references in the accompanying financial statements to
the number of Common shares and per-share amounts have been retroactively
restated to reflect the stock split.

In July 1997, the Company completed an initial public offering of 5,664,017
shares of Common stock, raising net proceeds of $93,608.  The proceeds of the
offering were used to redeem a portion of the 11.125% Senior Subordinated Notes
and to repay outstanding borrowings under the Company's credit facility (see
Note 6).

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
    ------------------------------------------ 

Principles of Consolidation
- ---------------------------

The consolidated financial statements include the accounts of Pierce Leahy
Corp., its 99%-owned subsidiary, Pierce Leahy Command Company, and its wholly-
owned subsidiaries, Monarch Box, Inc. and Advanced Box, Inc. All intercompany
accounts and transactions have been eliminated in consolidation.  The minority
interest in Pierce Leahy Command Company is not material to the consolidated
financial statements.

Use of Estimates
- ----------------

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

Inventories
- -----------

Inventories, which consist of storage containers, are stated at the lower of
cost (first-in, first-out) or market.

Property and Equipment
- ----------------------

Property and equipment are stated at cost.  Depreciation is provided using
straight-line and accelerated methods over the estimated useful lives of the
assets.

                                       25
<PAGE>
 
Goodwill
- --------

Goodwill reflects the cost in excess of fair value of the net assets of
companies acquired in purchase transactions.  Goodwill is amortized using the
straight-line method from the date of acquisition over the expected period to be
benefited, estimated at 30 years.  The Company assesses the recoverability of
goodwill, as well as other long-lived assets, based upon expectations of future
undiscounted cash flows in accordance with Statement of Financial Accounting
Standards ("SFAS") No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of." At December 31, 1997, no
adjustment of the carrying values of long-lived assets was necessary.

Client Acquisition Costs
- ------------------------

The unreimbursed costs of moving the records of new clients into the Company's
facilities and sales commissions related to new client contracts have been
capitalized and are included in intangible assets in the accompanying balance
sheets (see Note 4).  All such costs are being amortized on a straight-line
basis over six years, which represents the average initial contract term.  The
Company assesses whether amortization using a six year average initial contract
term varies significantly from using a specific contract basis.  Such difference
has not been material.

Deferred Rent
- -------------

Certain of the Company's leases for warehouse space provide for scheduled rent
increases over the lease terms.  The Company recognizes rent expense on a
straight-line basis over the lease terms, with the excess rent charged to
expense over the amount paid recorded as deferred rent in the accompanying
balance sheets.

Health Insurance Reserve
- ------------------------

The Company self-insures for benefit claims under a health insurance plan
provided to employees.  The self-insurance was limited to $100 in claims per
insured individual per year for both 1997 and 1996, and a liability for claims
incurred but not reported is reflected in the accompanying balance sheets.
Specific stop-loss insurance coverage is maintained to cover claims in excess of
the coverage per insured individual per year.

Income Taxes
- ------------

Prior to July 1, 1997, the Company was an S Corporation for federal and state
income tax purposes and, accordingly, income and losses were passed through to
the shareholders and taxed at the individual level.  On July 1, 1997, in
connection with the Company's initial public offering, the Company terminated
its S Corporation election and currently provides for federal and state income
taxes.

The Company applies SFAS No. 109, "Accounting for Income Taxes," which requires
the liability method of accounting for income taxes.  Under the liability
method, deferred tax assets and liabilities are recognized for the future tax
consequences, measured by enacted tax rates, attributable to temporary
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases and operating loss and tax credit
carry forward, for years which taxes are expected to be paid or recovered.

Revenue Recognition
- -------------------

Storage and service revenues are recognized in the month the respective service
is provided.  Storage material sales are recognized when shipped to the
customer.  Deferred revenues represent amounts invoiced for storage services in
advance of the rendering of the services.  The costs of storage and service
revenues 

                                       26
<PAGE>
 
are not separately distinguishable, as the revenue producing activities are
interdependent and costs are not directly attributable or allocable in a
meaningful way to those activities.

Foreign Currency
- ----------------

The balance sheets of Pierce Leahy Command Company, the Company's Canadian
subsidiary, are translated into U.S. dollars using the rate of exchange at
period end.  The statements of operations for the Canadian subsidiary are
translated into U.S. dollars using the average exchange rate for the period.
Net unrecognized exchange gains or losses resulting from the translation of the
balance sheets are accumulated and included as a separate component of
shareholders' equity (deficit).  Exchange gains and losses recognized during the
period are included in the Company's consolidated statements of operations.

New Accounting Pronouncements
- -----------------------------

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income" ("SFAS 130").  This statement requires
companies to classify items of other comprehensive income by their nature in a
financial statement and display the accumulated balance of other comprehensive
income separately from retained earnings and additional paid-in capital in the
equity section of a statement of financial position.  SFAS 130 is effective for
financial statements issued for fiscal years beginning after December 15, 1997.
Management believes that SFAS 130 will not have a material effect on the
Company's financial statements.

In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosure About Segments of an Enterprise and Related Information" ("SFAS
131").  This statement establishes additional standards for segment reporting in
the financial statements and is effective for fiscal years beginning after
December 15, 1997.  Management is currently evaluating the need to make
additional disclosures under SFAS No. 131.  However, this statement will not
have any impact on the Company's reported consolidated financial position or
results of operations.

Fair Value of Financial Instruments
- -----------------------------------

For certain of the Company's financial instruments, including accounts
receivable, accounts payable and accrued expenses, management believes that the
carrying amounts approximate fair value due to their short maturities.  The
carrying amount and estimated fair value of the Company's 11.125% Senior
Subordinated Notes at December 31, 1997 was $130,000 and $146,575, respectively.
The carrying amount and estimated fair value of the Company's 9.125% Senior
Subordinated Notes at December 31, 1997 was $120,000 and $125,700, respectively.
Both series of Notes are publicly traded, and accordingly, the fair value of the
Senior Subordinated Notes was estimated based on the quoted market price offered
for such securities.

Pro Forma Basic and Diluted Net Loss Per Share
- ----------------------------------------------

Prior to July 1, 1997, the Company was an S Corporation for federal and state
income tax purposes.  The pro forma income tax provision for 1997 reflects taxes
which would have been recorded on the historical loss before income taxes, at an
effective rate of 39%, had the Company not been an S Corporation during such
period.  The basic and diluted pro forma net loss per share is computed by
dividing pro forma net loss by the weighted average number of shares outstanding
during the period.

The Company continually evaluates whether events or circumstances have occurred
that indicate the remaining useful lives of the intangible assets should be
revised or the remaining balance of such assets may not be recoverable.  As of
December 31, 1997, the Company believes that no revisions to the remaining
useful lives or write-downs of intangible assets are required.

In July 1996, the Company issued $200,000 of Senior Subordinated Notes in a
private offering and were later exchanged for registered notes with
substantially identical terms (the "1996 Notes").  The 1996 Notes are general
unsecured obligations of the Company, subordinated in right of payment to senior
indebtedness of the Company and senior in right of payment to any current or
future subordinated indebtedness.  The 1996 Notes are guaranteed by the U.S.
subsidiaries of the Company and secured by a second lien on 65% of the stock of
the Canadian subsidiary. The 1996 Notes mature on July 15, 2006, and bear
interest at 11.125% per year, payable semiannually in arrears on January 15 and
July 15. The proceeds from the sale of the 1996 Notes were used to retire
certain existing indebtedness of the Company under its previous credit
facilities, to purchase certain properties from related party partnerships (see
Note 12), to redeem stock from a shareholder (see Note 8), to fund an
acquisition and for general corporate purposes.  The Company is in compliance
with all financial and operating covenants required under the indenture for the
1996 Notes.

                                       29

The Company had the option to redeem up to an aggregate of $70,000 principal
amount of the 1996 Notes at any time prior to July 15, 1999 with the net
proceeds of one or more public equity offerings at a redemption price equal to
110% of the aggregate principal amount so redeemed plus accrued interest to the
redemption date.  Upon completion of the Company's initial public offering of
its Common stock in July 1997 (see Note 1), the Company exercised this option to
redeem $70,000 principal amount of the 1996 Notes.  The resulting $7,000
prepayment penalty along with the write-off of a portion of the unamortized
deferred financing costs of $3,050, net of an income tax benefit of $4,014, was
recorded as an extraordinary charge in the accompanying consolidated statements
of operations.

In July 1997, the Company issued $120,000 of Senior Subordinated Notes (the
"1997 Notes") in a public offering.  The 1997 Notes are general unsecured
obligations of the Company, subordinated in right of payment to the senior
indebtedness of the Company and senior in right of payment to any current or
future subordinated indebtedness.  The 1997 Notes are guaranteed by the U.S.
subsidiaries of the Company and secured by a third lien on 65% of the stock of
the Canadian subsidiary. The 1997 Notes are equal in right of payment with the
1996 Notes.  The 1997 Notes mature on July 7, 2007, and bear interest at 9.125%
per year, payable semiannually in arrears on January 15 and July 15, commencing
January 15, 1998.  The proceeds from the sale of the 1997 Notes were used to
repay outstanding borrowings under its previous credit facility and for general
purposes.  The Company is in compliance with all financial and operating
covenants required under the indenture for the 1997 Notes.

In August 1997, the Company entered into a new credit facility (the "Credit
Facility") providing a revolving line of credit of U.S $140 million in
borrowings and CDN $35 million in borrowings for the Company's Canadian
subsidiary.  The Credit Facility is senior to all subordinated indebtedness of
the Company and is secured by substantially all of the assets of the Company,
and a first lien on 65% of the stock of the Canadian subsidiary.  Borrowings
under the facility bear interest at prime plus an applicable margin, or at LIBOR
plus an applicable margin, at the option of the Company.  The weighted average
interest rate on outstanding borrowings on the Canadian portion of the revolver
at December 31, 1997 was 6.38%.  In addition to interest and other customary
fees, the Company is obligated to remit a fee of 0.375% per year on unused
commitments, payable quarterly.  The aggregate available commitment under the
Credit Facility will be reduced on a quarterly basis beginning September 30,
2001.  The Credit Facility matures on June 30, 2004, unless previously
terminated.  The Company is in compliance with all financial and operating
covenants required under the Credit Facility.  The Company's available borrowing
capacity under the Credit Facility is contingent upon the Company meeting
certain financial ratios and other criteria.

In February 1998, the Company amended the Credit Facility to provide for
borrowings of U.S. $150 million and CDN $40 million.  All other terms and
conditions remained the same.

The highest amount outstanding under the current Canadian revolver during the
year ended December 31, 1997, was CDN $31,900.  The average amount outstanding
on the current Canadian portion of the revolver during the year was CDN $17,100,
while the weighted average interest rate was 6.12%.  There were no borrowings
under the current U.S. portion of the revolver in 1997.  The highest amounts
outstanding under previous U.S. and Canadian revolvers for the years ended
December 31, 1997 and 1996 were $117,763 and $6,000, the average amounts
outstanding were $69,338 and $3,097, and the weighted average interest rates
were 7.85% and 7.91%, respectively.

In connection with certain acquisitions completed in 1997 and 1996, notes for
$1,652 and $7,600, respectively, were issued to the sellers.  The notes bear
interest at rates ranging from 5% to 7% per year. The outstanding balance on
these notes as of December 31, 1997 and 1996 was $1,051 and $7,600,
respectively.  The outstanding balance on the notes as of December 31, 1997
matures through 1999.

In connection with the purchase of real estate from related parties in 1996 (see
Note 12), the Company assumed a mortgage of $1,114. The mortgage bears interest
at 10.5% and requires monthly principal and interest payments of $20 through
2002. The Company also assumed mortgage notes in connection with certain
acquisitions during 1997 and 1996 of $2,000 and $2,630, respectively. The notes
bear interest at 

                                       30
<PAGE>
 
rates of approximately 8% and require monthly principal and interest payments
ranging from $15 to $22 through 2001.

Future scheduled principal payments on the Company's long-term debt at December
31, 1997 are as follows:
 

        1998                              $  1,084
        1999                                   552
        2000                                   323

        2002                                 5,171
        2003 and thereafter                267,717
                                          --------
                                         $ 278,851
                                         =========

Upon entering into prior credit facilities in 1993 and 1994, the Company issued
warrants to certain lenders to purchase common stock.  Warrants to purchase
229,825 shares at $.01 per share were issued in 1993 and 55,073 shares at $2.68
per share were issued in 1994.

Management assigned an initial value of $338 to the 1993 warrants and $87 to the
1994 warrants for financial reporting purposes.  The Company called the warrants
in February 1996 at an amount which was determined by a formula defined in the
credit agreement.  The change in value of the redeemable warrants from the
initial value has been accreted through a charge to shareholder's equity
(deficit) in the accompanying financial statements.  The warrants were redeemed
for $2,625 in 1996.  There were no warrants outstanding during 1997.

Debt refinancings occurred in 1997, 1996 and 1995, resulting in the write-off of
previously deferred financing costs of  $3,050, $2,015 and $2,779, respectively,
and prepayment and other charges of $7,000 in 1997 and $500 in 1995.  Such
write-offs and charges have been recorded as extraordinary charges, net of tax,
in the accompanying consolidated statements of operations.

7. INCOME TAXES:

                        $11,438
                        ======= 

The provision for income taxes for the year ended December 31, 1997 consists of
a current tax provision for foreign taxes due on taxable income of the Company's
Canadian subsidiary, and deferred federal, state and foreign income taxes.  The
total deferred income tax provision includes a one-time tax charge of $6,600
recorded upon the termination of the Company's S corporation status.

The statement of operations for the year ended December 31, 1997 includes a pro
forma adjustment for the income taxes which would have been recorded if the
Company had been a C corporation for the entire period based on tax laws in
effect during the respective period.  The reconciliation of the federal
statutory 

                                       31
<PAGE>
 
income tax rate and the pro forma effective income tax rate is as follows for
the year ended December 31, 1997: 

 
     Federal statutory rate                          (34.0)%
     State income taxes                                 1.2
     Non-deductible depreciation and amortization       7.9

                                                     ------
                                                     (21.7)%
                                                     ======

Deferred taxes are determined based on the estimated future tax effects of
differences between the financial statement and tax basis of assets and
liabilities given the provisions of enacted tax laws.  Deferred taxes are
comprised of the following:
 
 
Current deferred income tax asset                  $  2,621
                                                   --------
 
Gross non-current deferred tax assets                10,269
Gross non-current deferred tax liabilities          (18,678)
                                                   --------
Total non-current deferred taxes                      8,409

                                                   ========

The tax effect of significant temporary differences representing deferred tax
assets and liabilities at December 31, 1997 are as follows:


     Basis difference of property and equipment    $(10,312)
     Basis difference in intangible assets           (5,076)
     Net operating loss carry forward                 5,112

          Net deferred tax liability               $  5,788
                                                   ========


The Company had federal and state net operating loss carry forwards available
for income tax and financial reporting purposes of approximately $12,631 and
$11,924, respectively, at December 31, 1997.  The net operating loss carry
forwards begin to expire in 2013.

The Tax Reform Act of 1986 provides for a tax at the corporate level on gains
realized on asset sales for a specified period following the election of
Subchapter S status.  Deferred taxes of $3,456 at December 31, 1996 were
provided for taxes which may have been triggered if the Company disposed of
certain acquired in connection with a certain purchase transaction.
 

8.    CAPITAL STOCK:
- ----  --------------

At December 31, 1997 and 1996, the Company's capital stock was comprised of the
following:
 
                                                         Preferred     Common
                                                        -----------  -----------

     Shares authorized                                   10,000,000   80,000,000
     Shares issued and outstanding December 31, 1997              -   16,477,728
     Shares issued and outstanding December 31, 1996              -   10,485,090

In 1996, the Company redeemed 105,910 shares of Common stock for $1,450 and
canceled these shares.

                                       32
<PAGE>
 
Certain shareholders of the Company entered into a voting trust agreement on
June 24, 1997.  The shares held in trust represent 56.6% of the outstanding
Common stock at December 31, 1997.  The trustees of the voting trust include the
President, Chief Executive Officer and Director of the Company and the Chairman
of the Board of Directors.  Each of the trustees has shared power to vote the
shares held in the voting trust.  The beneficial owners of interests in the
voting trust have the right to dispose of the shares to which they have
beneficial interests.

9.   STOCK OPTIONS:
     ------------- 

In September 1994, the Company established a non-qualified stock option plan
which provides for the granting of options to key employees to purchase an
aggregate of 1,208,433 shares of Common stock.  The shares available for grant
were increased by 284,898 in December 1996.  Options to purchase 153,570 shares
at $5.09 per share were granted on January 1, 1997, options to purchase 360,092
shares at $5.86 per share were granted on January 1, 1996 and options to
purchase 600,512 shares at $5.10 per share were granted on January 1, 1995.
Option grants have an exercise price equal to the fair market value of the
common stock on the date of grant.  Before the Company consummated its initial
public offering of Common stock in July 1997 (see Note 1), the fair market value
of the options was determined based upon a formula, as defined in the option
plan.  The options granted vest in five equal annual installments beginning on
the first anniversary of the date of grant, except as discussed below.

Upon the consummation of the Company's initial public offering of Common stock
in July 1997, options granted during 1997 became fully vested and exercisable as
provided for under the plan.  The Company recorded a non-recurring, non-cash
compensation charge of approximately $1,752 relating to those options,
representing the difference between the exercise price and the deemed value for
accounting purposes.

In April 1997, the Company adopted its 1997 Stock Option Plan (the "1997 Plan")
which provides for the granting of stock options to purchase up to 1,500,000
shares of Common stock to employees, officers, directors, consultants and
advisors of the Company.  The 1997 Plan will be administered by the Compensation
Committee of the Board of Directors (the "Committee").  Grants may consist of
incentive stock options or nonqualified stock options.  The option price of any
incentive stock option granted will not be less than the fair value of the
underlying shares of Common stock on the date of grant.  The option price of a
non-qualified stock option will be determined by the Committee and may be
greater than, equal to or less than the fair market value of the underlying
shares of Common stock on the date of grant.  The term of each option will be
determined by the Committee, provided that the exercise period may not exceed 10
years from the date of grant.  The options granted may be subject to vesting and
other conditions.  In the event of a change in control (as defined in the 1997
Plan), all outstanding options will become fully exercisable.  At December 31,
1997, no options were granted under the 1997 Plan.

The Company accounts for its option plans under APB Opinion No. 25, "Accounting
for Stock Issued to Employees," under which no compensation cost has been
recognized.  In 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation."  SFAS No. 123 establishes a fair
value based method of accounting for stock-based compensation plans.  This
statement also applies to transactions in which an entity issues its equity
instruments to acquire goods or services from non-employees.  SFAS No. 123
requires that an employer's financial statements include certain disclosures
about stock-based employee compensation arrangements regardless of the method
used to account for the plan.

At December 31, 1997, the total options outstanding are 1,114,174 with exercise
prices between $5.09 and $5.86 and a weighted average exercise price of $5.34.
The options outstanding at December 31, 1997 contain no expiration dates.  At
December 31, 1997,  options to purchase 465,793 shares of Common stock are fully
vested and exercisable.   The fair value of each option grant is estimated on
the date of grant using the Black-Scholes option pricing model with the
following assumptions used for the grants in 1997, 1996 and 1995:

10.  COMMITMENTS AND CONTINGENCIES:
- ---- ----------------------------- 

Operating Leases
- ----------------

At December 31, 1997, the Company was obligated under non-cancelable operating
leases, including the related-party leases discussed below, for warehouse space,
office equipment and transportation equipment.  These leases expire at various
times through 2015 and require minimum rentals, subject to escalation, as
follows:

 
       1998                                   $ 30,963
       1999                                     28,180
       2000                                     25,838
       2001                                     23,818
       2002                                     21.346
       2003 and thereafter                      76,583
                                               -------
                                              $206,728
                                               -------

Rent expense for all leases was approximately $21,657, $17,008, and $14,098 for
the years ended December 31, 1997, 1996 and 1995, respectively.  Some of the
leases for warehouse space provide for purchase options on the facilities at
certain dates.

The Company leases office and warehouse space at prices which, in the opinion of
management, approximate market rates from entities which are owned by certain
shareholders, officers and employees of the Company.  Rent expense on these
leases was approximately $845, $9,019, and $8,201 for the years ended December
31, 1997, 1996 and 1995, respectively.  A significant portion of the related
party rent expense was reduced through the purchase of certain real estate and
the buy-out of certain lease interests in July 1996 (see Note 12).

                                       34
<PAGE>
 
Other Matters
- -------------

The Company entered into consulting agreements with several of the former owners
of acquired businesses (see Note 14).  These agreements require minimum payments
of $74 in 1998.

The Company is party to various claims arising in the ordinary course of
business.  Although the ultimate outcome of these matters is presently not
determinable, management, after consultation with legal counsel, does not
believe that the resolution of these matters will have a material adverse effect
on the Company's consolidated financial position or results of operations.

In June 1997 the Company entered into a tax indemnification agreement with the
then current shareholders which provides for: (i) the distribution to such
shareholders of cash equal to the product of the Company's taxable income for
the period from January 1, 1997 until July 1, 1997 and the sum of the highest
effective federal and state income tax rate applicable to any current
shareholder, less any prior distributions to such shareholders to pay taxes for
such period, and (ii) an indemnification of such shareholders for any losses or
liabilities with respect to any additional taxes (including interest, penalties
and legal fees) resulting from the Company's operations during the period in
which it was a Subchapter S Corporation.

11.  EARNINGS PER SHARE:  
     ------------------ 

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share,"  ("SFAS No. 128").
SFAS No. 128 requires dual presentation of basic and diluted earnings per share.
According to SFAS No. 128, basic earnings per share, which replaces primary
earnings per share, is calculated by dividing net income (loss) by the weighted
average number of common shares outstanding for the period.  Diluted earnings
per share, which replaces fully diluted earnings per share, reflects the
potential dilution from the exercise or conversion of securities into Common
stock, such as stock options and warrants.  The Company was required to and did
adopt SFAS No. 128 during the period ended December 31, 1997.

In 1997 there were no dilutive effects of stock options or warrants as the
Company had a loss before extraordinary item.  In 1996, the weighted average of
shares outstanding was 10,546,871.  The dilutive effects of the weighted average
number of stock options and warrants outstanding was 84,059 shares.  In 1995,
the weighted average number of shares outstanding was 10,591,090.  The dilutive
effects of the weighted average number of stock options and warrants outstanding
was 299,186 shares.


12.  RELATED PARTY TRANSACTIONS:
     -------------------------- 

In August 1996, the Company purchased certain real estate previously leased and
other assets from two partnerships, whose partners were shareholders of the
Company.  The payment for the purchased real estate and other assets was $11,018
plus the assumption of a $1,114 mortgage.  Since the transaction was with
related parties, the real estate was recorded at its depreciated cost.  As a
result, the Company charged the elimination of the deferred rent liability on
the leases and the difference between the purchase price and the depreciated
cost, which together totaled $4,132, to shareholders' equity (deficit) as a
deemed distribution.  In addition, the Company bought out certain lease
commitments from a related party partnership for $2,764.  This lease buy-out was
recorded as a non-recurring charge in the 1996 consolidated statement of
operations.

The Company had an agreement with a shareholder of the Company that required
payments of $60 per year for five years upon the death of the shareholder.  The
present value of this benefit was recorded as a liability by the Company.  In
July 1996, the Company decided to make monthly pension payments to the
shareholder and terminated the previous agreement.  The pension payments are $8
per month until the death of the shareholder or his spouse.  The $490 difference
between the present value of this benefit and the 

                                       35
<PAGE>
 
liability previously reported was recorded as a non-recurring charge in the 1996
consolidated statement of operations.

The Company paid financial advisory fees to an investment banking firm of which
a director of the Company was a managing director.  The fees were approximately
$62, $800 and $700 in 1997, 1996 and 1995, respectively.  In addition, in 1997
the investment banking firm received $1,800 from the underwriters on the 1997
Notes and initial public offering.

The Company paid real estate advisory fees to a firm of which a director of the
Company is the owner.  The fees were approximately $88 in 1997.  There were no
fees paid to the firm in 1996 and 1995.

In December 1993, the Company borrowed $80 from a shareholder which bore
interest at 7%.  The note was repaid in 1996.

As of December 31, 1997, an officer had borrowed $210 from the Company.
Interest accrues on the loan at 8.875% a year.

13.  EMPLOYEE BENEFIT PLANS:
- ---- ---------------------- 

The Company maintains a discretionary profit sharing and a 401(k) plan for
substantially all full-time employees over the age of 20  1/2 and with more than
1,000 hours of service.  Participants in the 401(k) plan may elect to defer a
specified percentage of their compensation on a pretax basis.  The Company is
required to make matching contributions equal to 25% of the employee's
contribution up to a maximum of 2% of the employee's annual compensation.
Participants become vested in the Company's matching contribution over three to
seven years.  The expense relating to these plans was $892, $1,122, and $591 for
the years ended December 31, 1997, 1996 and 1995, respectively.

14.  ACQUISITIONS:
- ---- ------------ 

In 1996, the Company completed 12 acquisitions for an aggregate cash purchase
price of $62,165 (of which $14,000 was for one transaction in May 1996 and
$13,500 was for another transaction in October 1996; all others were
individually less than $8,000). In 1997, the Company completed 17 acquisitions,
of which 15 were recorded under the purchase method of accounting while the
other two acquisitions were accounted for as pooling of interests, the 15
acquisitions had an aggregate purchase price of $109,098, consisting of $102,086
in net cash, 163,266 shares of Common stock with a deemed value of  $4,500, and
$1,652 in Seller notes.  For purposes of computing the purchase price for
accounting purposes, the value of the shares issued is determined using a
discount of 10% from the market value at the day of issuance due to certain
restrictions on the sale and transferability of shares issued.  The most
significant of these acquisitions was for one transaction of $9,084 in January
1997 and another for $62,000 in April 1997; all others were individually less
than $8,000.  In addition to these cash payments, acquisitions in 1997 and 1996
provided for noncompete obligations of $60 and $400, respectively, payable over
one year.  The noncompete liability at December 31, 1997 and 1996 was $347 and
$783, respectively. The results of operations for each of these acquisitions
have been included in the consolidated results of the Company from the
respective acquisition dates.  The excess of the fair value of the assets and
liabilities acquired has been allocated to goodwill ($91,047 and $43,062 in 1997
and 1996, respectively) and is being amortized over the estimated benefit period
of 30 years.  In connection with certain of the acquisitions, the Company
entered into consulting agreements with several of the former owners of the
acquired businesses which require aggregate commitments of $74 at December 31,
1997 (see Note 10).

During 1997, the Company also completed two mergers with records management
businesses by exchanging 165,355 shares of Common stock for the Common stock of
these entities.  These mergers constituted tax free reorganizations and have
been accounted for as pooling of interests under Accounting Principles Board
Opinion No. 16.  Prior periods have not been restated for the acquisitions due
to the immateriality of the transactions, and the book value of net assets
acquired of $407 has been recorded as additional paid-in 

                                       36
<PAGE>
 
capital. The results of operations for each acquisition have been included in
the consolidated results of the Company from their respective acquisition dates.

Subsequent to December 31, 1997, the Company completed five acquisitions of
record management businesses for an aggregate cash purchase price of
approximately $41,700.  Certain purchase agreements contain purchase price
adjustments and earn-out provisions contingent upon future performance and other
criteria that could affect the net cash paid for the entity.  The acquisitions
were accounted for under the purchase method of accounting.  The $36,700 excess
purchase price over the underlying fair value of the assets and liabilities
acquired has been allocated to goodwill.

A summary of the net cash paid for the purchase price of the completed
acquisitions is as follows:

                                                 1997                1996

The pro forma results have been prepared for comparative purposes only and are
not necessarily indicative of the actual results of operations had the
acquisitions taken place as of January 1, 1996, or the results that may occur in
the future.  Furthermore, the pro forma results do not give effect to all cost
savings or incremental costs which may occur as a result of the integration and
consolidation of the acquired companies.

In February 1998, the Company signed a definitive agreement to purchase a
regional records management company for CDN $90.0 million, which it intends to
finance either through borrowings under the Credit Facility or through the
issuance of additional notes.  The acquisition is subject to due diligence and
other customary conditions.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To Pierce Leahy Corp.:

     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements for Pierce Leahy Corp. and have issued our
report thereon dated February 27, 1998.  Our audit was made for the purpose of
forming an opinion on the basic financial statements taken as a whole.  The
schedule of valuation and qualifying accounts is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part of
the basic financial statements.  This schedule has been subjected to the
auditing procedures applied in the audit of the basic financial statements and,
in our opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.

          3.   Voting Trust Certificates.
               ------------------------- 

          (a) The Trustees shall maintain a voting trust certificate register in
which each holder of a voting trust certificate issued under this Agreement, and
the number of shares represented by each voting trust certificate will be
identified.  The voting trust certificates shall be in substantially the
following form:

                             "No. VT_________________
                            _________________ Shares
                                        
                               PIERCE LEAHY CORP.
                           A Pennsylvania Corporation
                   Voting Trust Certificate for Common Stock
                                        
          This certifies that __________________ or registered assigns is
entitled to all the benefits arising from the transfer to the Trustees under the
Voting Trust Agreement hereinafter mentioned, of ____ shares of common stock of
Pierce Leahy Corp., a Pennsylvania corporation (hereinafter called the
"Company"), as provided in such Voting Trust Agreement and subject to the terms
thereof.   The registered holder hereof, or assigns, is entitled to receive
payment, in the manner set forth in the Voting Trust Agreement, equal to the
amount of dividends, if any, received by the Trustees upon the number of shares
of capital stock of the Company in respect of which this certificate is issued;
provided, however, that any dividends received by the Trustees in common or
- --------  -------                                                          
other stock of the Company having general voting powers shall be held by the
Trustees under the Voting Trust Agreement and shall be represented by voting
trust certificates issued in form similar hereto. Until the Trustees shall have
delivered the shares of stock held under such Voting Trust Agreement to the
holders of the trust certificates, or to the Company, as specified in such
Voting Trust Agreement, the Trustees shall possess and shall be entitled to
exercise all rights and powers of an absolute owner of such shares of stock,
including the right to vote thereon for every purpose, and to execute consents
in respect thereof for every purpose, it being expressly stipulated that no
voting right passes to the owner hereof, or such owner's assigns, under this
certificate or any agreement, expressed or implied.

          This certificate is issued, received, and held under, and the rights
of the owner hereof are subject to, the terms of a Voting Trust Agreement, as
amended and restated as of ________ __, 1998, among the Company and Leo W.
Pierce, Sr. and J. Peter Pierce in trust (such agreement, as it may be amended
from time to time, the "Voting Trust Agreement"), and certain shareholders of
the Company (copies of which Voting Trust Agreement, and of every agreement
amending or supplementing the same, are on file in the principal office of the
Company, and shall be open to the inspection of any shareholder of the Company,
during business hours); to all the provisions of which Voting Trust Agreement
the holder of this certificate, and such holder's heirs, personal
representatives, successors and assigns, by acceptance hereof, assents and is
bound as if such Voting Trust Agreement had been signed by such person.

          Subject to Sections 8, 9 and 12 of the Voting Trust Agreement, in the
event of the dissolution or total or partial liquidation of the Company, the
moneys, securities or property received by the Trustees in respect of the shares
of stock deposited under such Voting Trust Agreement shall be distributed among
the registered holders of trust certificates in proportion to their interests as
shown on the books of the Trustees.

          Except as otherwise provided in Sections 9 and 12 of the Voting Trust
Agreement, in the event that any dividend or distribution other than in cash or
shares of common or other stock of the Company having general voting powers is
received by the Trustees, the Trustees shall distribute the same to the
registered holders of voting trust certificates, on the date of such
distribution, or to the registered certificate holders at the close of business
on the date fixed by the Trustees for taking a record to determine the
certificate holders entitled to such distribution, pursuant to the provisions of
Paragraph 6 of the Voting Trust Agreement.  Such distribution shall be made to
the certificate holders ratably in accordance with the number of shares
represented by their respective voting trust certificates.  Cash dividends shall
be treated as set forth in Section 6 of the Voting Trust Agreement.

          Share certificates for the number of shares of common stock then
represented by this certificate, or the net proceeds in cash or property
representing such shares, shall be due and deliverable hereunder upon the
termination of such Voting Trust Agreement as provided therein.  The Voting
Trust Agreement shall continue in full force and effect until June 23, 2007
(subject to extension as hereinafter set forth), unless terminated prior
thereto, as provided in the Voting Trust Agreement.  The Voting Trust Agreement
may be extended as the parties may agree, as provided in the Voting Trust
Agreement.

          This certificate is transferable on the books of the Trustees at the
office of the Trustees (or elsewhere as designated by the Trustees) by the
holder hereof, either in person or by attorney duly authorized, in accordance
with the rules established for that purpose by the Trustees and on surrender of
this certificate properly endorsed, subject to compliance with all applicable
state and federal securities laws.  Title to this certificate when duly endorsed
shall, to the extent permitted by law, be transferable with the same effect as
in the case of a negotiable instrument.  Each holder hereof agrees that delivery
of this certificate, duly endorsed by any holder hereof, shall vest title hereto
and all rights hereunder in the transferee; provided, however, that the Trustees
                                            --------  -------                   
may treat the registered holder hereof, or when presented duly endorsed in blank
the bearer hereof, as the absolute owner hereof, and of all rights and interests
represented hereby, for all purposes whatsoever, and the Trustees shall not be
bound or affected by any notice to the contrary, or by any notice of any trust,
whether express or implied, or constructive, or of any charge or equity
respecting the title or ownership of this certificate, or the shares of stock
represented hereby; provided, however, that no delivery of stock certificates
hereunder, or the proceeds thereof, shall be made without surrender hereof
properly endorsed.

          This certificate shall not be valid for any purpose until duly signed
by the Trustees.

          The word "Trustees" as used in this certificate means the Trustees or,
if only one Trustee is remaining, as provided in the Voting Trust Agreement,
such Trustee, acting under the Voting Trust Agreement.

NOTE: THE SIGNATURE TO THIS ASSIGNMENT MUST CORRESPOND WITH THE NAME AS WRITTEN
UPON THE FACE OF THIS CERTIFICATE IN EVERY PARTICULAR, WITHOUT ALTERATION,
ENLARGEMENT, OR ANY CHANGE WHATEVER.  ALL ENDORSEMENTS, IN THE DISCRETION OF THE
TRUSTEES, SHALL BE GUARANTEED BY A BANK OR TRUST COMPANY SATISFACTORY TO THE
TRUSTEES."

               (b) Any voting trust certificates issued under the Original
Agreement shall be deemed issued pursuant hereto without the need to be returned
to the Trustees for reissuance, and any references therein to the Original
Agreement shall be deemed to be references to this Agreement.

          4.   Transfer of Certificates.
               ------------------------ 

               (a) The voting trust certificates, if and to the extent
transferable under applicable securities law or under any agreement restricting
transferability, shall be transferable at the principal office of the Trustees
(and at such other office as the Trustees may designate by an instrument in
writing signed by the Trustees and sent by mail to the registered holders of
voting trust certificates), on the books of the Trustees, by the registered
owner thereof, either in person or by attorney thereto duly authorized, upon
surrender thereof, according to the rules established for that purpose by the
Trustees, subject to the provisions set forth in this Section. If a transfer of
voting trust certificates is so permitted, the holder shall notify the Trustees
of the details of such transfer, including the name, address and social security
number of the transferee and number of shares as to which the beneficial
interest is being transferred, and shall surrender to the Trustees the voting
trust certificate or certificate representing such shares, properly endorsed for
transfer, and the Trustees shall, upon receipt of such notice and voting trust

                                      -4-
<PAGE>
 
certificate(s), transfer the voting trust certificates on the voting trust
certificate registry and issue a new voting trust certificate to the transferee.
Until so transferred, the Trustees may treat the record holders of voting trust
certificates as the owners of said voting trust certificates for all purposes
whatsoever.  As a condition to making any transfer or delivery of voting trust
certificates, the Trustees may require compliance by the transferee with any
applicable federal or state statute and the payment of a sum sufficient to pay
for any stamp tax or other governmental charge in connection therewith.  No
transfer of voting trust certificates shall in any way remove the shares
represented by such certificate or certificates from being held by the Trustees
under this Agreement and any transferee, by accepting such transfer, does hereby
consent to be bound by the terms of this Agreement, and upon becoming a holder
of voting trust certificates shall be deemed to be a party hereto as though an
original signatory hereto.

               (b) If a voting trust certificate is lost, stolen, mutilated, or
destroyed, the holder thereof shall promptly notify the Trustees and the
Trustees, in the Trustees' discretion, may issue to such holder a duplicate of
such certificate upon receipt of: (i) evidence of such fact satisfactory to the
Trustees; (ii) indemnity satisfactory to the Trustees (whether by bond or
otherwise in such form or amount and with such surety as the Trustees may
require to indemnify the Trustees against loss or liability that might arise due
to the issuance of such new voting trust certificate); (iii) the existing
certificate, if mutilated; and (iv) the reasonable fees and expenses of the
Trustees in connection with the issuance of a new trust certificate.  The
Trustees shall not be required to recognize any transfer of a voting trust
certificate not made in accordance with the provisions hereof, unless the person
claiming such ownership shall have produced indicia of title satisfactory to the
Trustees, and shall in addition deposit with the Trustees indemnity satisfactory
to the Trustees.

          5.   Termination Procedure.
               ----------------------

               (a) Any Shareholder may from time to time give the Trustees
written notice that such Shareholder desires to withdraw all or part of such
Shareholder's shares from the voting trust created hereby in order to donate
such shares to a non-profit corporation, foundation or similar entity having a
charitable purpose or to sell such shares to someone other than another
Shareholder within fifteen (15) days of the delivery of the notice. Voting trust
certificates representing shares to be withdrawn shall accompany the notice.
Within five (5) days after receipt of such notice and certificates, Trustees
shall deliver to the Company stock certificates and instructions to deliver the
requisite number of shares to the Shareholder who delivered the notice of
withdrawal to the Trustees. In the event the Shareholder does not donate or sell
all of the shares withdrawn from the voting trust, (i) the Shareholder shall
deliver the stock certificate representing the shares not donated or sold to the
Trustees who shall deliver it to the Company for reissue to the Trustees, (ii)
the reissued stock certificate shall be held by the Trustees pursuant to this
Agreement and (iii) the Trustees shall issue to the Shareholder a voting trust
certificate representing such shares.

               (b) Any Shareholder may from time to time give the Trustees
written notice in the form attached as Exhibit B hereto that such Shareholder
desires to withdraw all or a part of such Shareholder's shares from the voting
trust created hereby in order to pledge such shares to a broker as collateral
for a margin account with such broker (any such shares so withdrawn, together
with any shares of common or other stock of the Company having general 

                                      -5-
<PAGE>
 
voting power paid as a dividend or issued upon exercise of any subscription
rights with respect to such shares, until any of the foregoing are sold as
permitted hereunder or reissued to the Trustees, "Margin Shares").  The
Shareholder shall send to the Trustees, along with such notice, the voting trust
certificates representing the Margin Shares to be withdrawn and a duly executed
proxy in the form attached hereto as Exhibit C.  Within five (5) days after
receipt of such notice, proxy and certificates, the Trustees shall deliver to
the Company stock certificates and instructions to deliver the requisite number
of shares to the Shareholder who delivered the notice of withdrawal to the
Trustees for purposes of placing the Margin Shares in a margin account.  If
applicable, the stock certificate issued to the Shareholder with respect to such
Margin Shares shall contain a standard restrictive legend under the Securities
Act of 1933.  If the Shareholder otherwise would be entitled to have such legend
removed prior to the sale of such Margin Shares and so requests the Company and
the Trustees to remove such legend solely for the purpose of registering the
Margin Shares in "street name" or the name of the broker in whose margin account
the Margin Shares are held, the Company shall honor such request if the
Shareholder arranges for the registered holder or broker, as applicable, to
provide a duly executed proxy to the Trustees substantially similar in form to
Exhibit C attached hereto to vote such Margin Shares while held in the margin
account (or makes other arrangements satisfactory to the Trustees with respect
to voting such shares at the direction of the Trustees while subject to the
margin account).  Upon receipt of written notice from the Trustees that such a
satisfactory arrangement has been made, the Company will authorize the issuance
of a certificate for such Margin Shares in "street name" or in the name of the
broker without a restrictive legend.  Any Margin Shares sold by or on behalf of
the broker shall be sold free and clear of the proxy, which by its terms shall
terminate upon such sale.  Any Shareholder who has Margin Shares shall give, or
cause to be given, to the Trustees a notice when all or a portion of such Margin
Shares are sold, as soon as practicable after such sale.  In the event the
Shareholder ceases using all or part of such Margin Shares as collateral for a
margin account, (i) the Shareholder shall deliver or cause to be delivered the
stock certificate representing the Margin Shares no longer subject to the margin
account to the Trustees who shall deliver such certificate to the Company for
reissue to the Trustees, (ii) the reissued stock certificate shall be held by
the Trustees pursuant to this Agreement and (iii) the Trustees shall issue to
the Shareholder a voting trust certificate representing such shares.

               (c) Any Shareholder may, once in any twelve-month period, give
the Trustees written notice in the form attached as Exhibit D hereto that such
Shareholder has a bona fide intent (subject to market and other conditions) to
sell up to such number of shares as specified in the notice within twelve months
from the date of such notice and therefore desires to withdraw such shares from
the voting trust created hereby in order to facilitate such possible sale (any
such shares so withdrawn, together with any shares of common or other stock of
the Company having general voting power paid as a dividend or issued upon
exercise of any subscription rights with respect to such shares, until any of
the foregoing are sold as permitted hereunder or reissued to the Trustees,
"Designated Shares" and together with Margin Shares, "Proxy Shares"). The
Shareholder shall send to the Trustees, along with such notice, the voting trust
certificates representing the Designated Shares to be withdrawn and a duly
executed proxy in the form attached hereto as Exhibit C. Within five (5) days
after receipt of such notice, proxy and certificates, the Trustees shall deliver
to the Company stock certificates and instructions to deliver the requisite
number of shares to the Shareholder who delivered the notice of withdrawal to
the Trustees as set forth above. If applicable, the stock certificate issued to
the

                                      -6-
<PAGE>
 
Shareholder with respect to such Designated Shares shall contain a standard
restrictive legend under the Securities Act of 1933.  If the Shareholder
otherwise would be entitled to have such legend removed prior to the sale of
such Designated Shares and so requests the Company and the Trustees to remove
such legend solely for the purpose of registering the Designated Shares in
"street name," the Company shall honor such request if the Shareholder arranges
for the registered holder to provide a duly executed proxy to the Trustees
substantially similar in form to Exhibit C attached hereto to vote such
Designated Shares while held by the broker (or makes other arrangements
satisfactory to the Trustees with respect to voting such shares at the direction
of the Trustees while held by the broker).  Upon receipt of written notice from
the Trustees that such a satisfactory arrangement has been made, the Company
will authorize the issuance of a certificate for such Designated Shares in
"street name" without a restrictive legend.  Any Designated Shares sold by the
Shareholder shall be sold free and clear of the proxy, which by its terms shall
terminate upon such sale.  Any Shareholder who has Designated Shares shall give,
or cause to be given, to the Trustees a notice when all or a portion of such
Designated Shares are sold, as soon as practicable after such sale.  In the
event the Shareholder determines not to sell all or part of such Designated
Shares, (i) the Shareholder shall deliver or cause to be delivered the stock
certificate representing the Designated Shares not to be sold to the Trustees
who shall deliver such certificate to the Company for reissue to the Trustees,
(ii) the reissued stock certificate shall be held by the Trustees pursuant to
this Agreement and (iii) the Trustees shall issue to the Shareholder a voting
trust certificate representing such shares.

               (d) Subject to the provisions of Section 12, upon the termination
of this Agreement at any time, as hereinafter provided, the Trustees, at such
time as the Trustees may choose during the period commencing 20 days before and
ending 20 days after such termination, shall mail written notice of such
termination to the registered owners of the voting trust certificates and any
Shareholder who beneficially owns any Proxy Shares (each, a "Proxy
Shareholder"), at the addresses appearing on the transfer books of the Trustees.
After the date specified in any such notice (which date shall be fixed by the
Trustees), (i) the voting trust certificates shall cease to have any effect, and
the holders of such voting trust certificates shall have no further rights under
this Agreement other than to receive certificates for shares of the Company or
other property distributable under the terms hereof and upon the surrender of
such voting trust certificates, and (ii) any proxy given to the Trustees
relating to any Proxy Shares shall be deemed terminated.

               (e) Within 30 days after the termination of this Agreement, the
Trustees shall deliver, to the registered holders of all voting trust
certificates, certificates for the number of shares of the capital stock of the
Company represented thereby, upon the surrender of such voting trust
certificates properly endorsed, such delivery to be made in each case at the
office of the Trustees.

               (f) At any time subsequent to 30 days after the termination of
this Agreement, the Trustees may deposit with the Company share certificates
representing the number of shares of capital stock represented by the voting
trust certificates then outstanding, with authority in writing to the Company to
deliver such share certificates in exchange for voting trust certificates
representing a like number of shares of the capital stock of the Company and for
the Company to call upon and require all holders of voting trust certificates to
so surrender them; and upon such deposit all further liability of the Trustees
for the delivery of such share

                                      -7-
<PAGE>
 
certificates and the delivery or payment of dividends upon surrender of the
voting trust certificates shall cease, and the Trustees shall not be required to
take any further action hereunder.

          6.   Dividends.
               --------- 

               (a) Until the termination of this Agreement pursuant to the terms
of Section 12, the holder of each voting trust certificate shall be entitled to
receive from the Trustees payments equal to the cash dividends, if any, received
by the Trustees upon a like number and class of shares of capital stock of the
Company as is called for by each such voting trust certificate standing in the
name of such holder in the voting trust certificate register. If any dividend in
respect of the stock deposited with the Trustees are paid, in whole or in part,
in shares of common or other stock of the Company having general voting powers,
the Trustees shall likewise hold, subject to the terms of this Agreement, the
certificates for shares of stock which are received by the Trustees on account
of such dividend, and the holder of each voting trust certificate representing
shares of stock on which such stock dividend has been paid shall be entitled to
receive a voting trust certificate issued under this Agreement for the number of
shares and class of stock received as such dividend with respect to the shares
represented by such voting trust certificate. Holders entitled to receive the
dividends described above shall be those registered as such on the transfer
books of the Trustees at the close of business on the day fixed by the Company
for the taking of a record to determine those holders of its shares of stock
entitled to receive such dividends, or if the Trustees have fixed a date, as
hereinafter in this Section provided, for the purpose of determining the holders
of voting trust certificates entitled to receive such payment or distribution,
those holders registered as such at the close of business on the date so fixed
by the Trustees.

               (b) Except as otherwise provided in Section 12, if any dividend
in respect of the stock deposited with the Trustees are paid other than in cash
or in capital stock having general voting powers, then the Trustees shall
distribute the same among the holders of voting trust certificates registered as
such at the close of business on the day fixed by the Trustees for taking a
record to determine the holders of voting trust certificates entitled to receive
such distribution. Such distribution shall be made to such holders of voting
trust certificates ratably, in accordance with the number of shares represented
by their respective voting trust certificates.

               (c) The transfer books of the Trustees may be closed temporarily
by the Trustees for a period not exceeding 20 days preceding the date fixed for
the payment or distribution of dividends or the distribution of assets or
rights, or at any other time in the discretion of the Trustees. In lieu of
providing for the closing of the books against the transfer of voting trust
certificates, the Trustees may fix a date not exceeding 20 days preceding any
date fixed by the Company for the payment or distribution of dividends, or for
the distribution of assets or rights, as a record date for the determination of
the holders of voting trust certificates entitled to receive such payment or
distribution or to receive such assets or exercise such rights, or for the
purpose of determining the holders of voting trust certificates entitled to vote
at any meeting of the holders or to determine any other thing, act or rights to
be exercised, done or performed by the holders, and the holders of voting trust
certificates of record at the close of business on such date shall exclusively
be entitled to participate in such payments or distribution 

                                      -8-
<PAGE>
 
or exercise of rights.

               (d) In lieu of receiving cash dividends upon the capital stock of
the Company and paying the same to the holders of voting trust certificates
pursuant to the provisions of this Agreement, the Trustees may instruct the
Company in writing to pay such dividends to the holders of the voting trust
certificates. Upon receipt of such written instructions, the Company shall pay
such dividends directly to the holders of the voting trust certificates. Upon
such instructions being given by the Trustees to the Company, and until revoked
by the Trustees, all liability of the Trustees with respect to such dividends
shall cease. The Trustees may at any time revoke such instructions and by
written notice to the Company direct it to make dividend payments to the
Trustees.

          7.   Subscription Rights.  In case any stock or other securities of
               -------------------                                           
the Company are offered for subscription to the holders of capital stock of the
Company deposited hereunder, the Trustees, promptly upon receipt of notice of
such offer, shall mail a copy thereof to each of the holders of the voting trust
certificates.  Upon receipt by the Trustees, at least five days prior to the
last day fixed by the Company for subscription and payment, of a request from
any such registered holder of voting trust certificates to subscribe in such
holder's behalf, accompanied with the sum of money required to pay for such
stock or securities (not in excess of the amount subject to subscription in
respect to the shares represented by the voting trust certificate held by such
certificate holder), the Trustees shall make such subscription and payment, and
upon receiving from the Company the certificates for shares or securities so
subscribed for, shall issue to such holder a voting trust certificate in respect
thereof if the same be stock having general voting powers, but if the same be
securities other than stock having general voting powers, the Trustees shall
mail or deliver such securities to the certificate holder in whose behalf the
subscription was made, or may instruct the Company to make delivery directly to
the certificate holder entitled thereto.  In case any reduction of the shares of
the Company shall have been duly authorized, the Trustees are hereby authorized
to make such surrender of shares of the Company held by the Trustees hereunder,
pro-rata on behalf of all holders of voting trust certificates, as may be
required under the terms pursuant to which such reduction is to be effected, and
to receive and hold any and all shares of the Company issued in exchange for
such surrendered shares.  Following any such action, the voting trust
certificates issued and outstanding pursuant hereto shall be deemed to represent
a proportionately reduced number of shares.

          8.   Dissolution of Company.  Except as otherwise provided in Section
               ----------------------                                          
12, in the event of the dissolution or total or partial liquidation of the
Company, whether voluntary or involuntary, the Trustees shall receive the
moneys, securities, rights, or property to which the holders of the capital
stock of the Company deposited hereunder are entitled, and shall timely
distribute the same among the registered holders of voting trust certificates in
proportion to their interests, as shown by the books of the Trustees, or the
Trustees may in the Trustees' discretion deposit such moneys, securities,
rights, or property with any bank as the Trustees may select, with authority and
instructions to distribute the same as above provided, and upon such deposit,
this Agreement shall terminate and all further obligations or liabilities of the
Trustees in respect of such moneys, securities, rights, or property so deposited
shall cease and terminate.

          9.   Reorganization of Company.  Except as otherwise provided in
               -------------------------                                  
Section 12,

                                      -9-
<PAGE>
 
in the event the Company is merged into or consolidated with another
corporation, or all or substantially all of the assets of the Company are
transferred to another corporation pursuant to a plan requiring the Company's
assets to be distributed in liquidation, or all the shares of the Company are to
be exchanged in connection with a reorganization of the Company, then in
connection with such transaction or series of transactions the term "Company"
for all purposes of this Agreement shall be taken to include such successor
corporation, and the Trustees shall receive and hold under this Agreement any
stock of such successor corporation received on account of the ownership, as
Trustees hereunder, of the shares of stock held hereunder prior to such merger,
consolidation or transfer.  Voting trust certificates issued and outstanding
under this Agreement at the time of such merger, consolidation, or transfer may
remain outstanding, or the Trustees may, in their discretion, substitute for
such voting trust certificates new voting trust certificates in appropriate
form, and the terms "stock," "shares" and "capital stock" as used herein shall
be taken to include any stock which may be received by the Trustees in lieu of
all or any part of the capital stock of the Company.

          10.  Rights of Trustees.
               ------------------ 

               (a) Until the actual delivery to the holders of voting trust
certificates issued hereunder of stock certificates in exchange therefor, and
until the surrender of the voting trust certificates for cancellation, the
Trustees shall possess and have the exclusive right, except as otherwise
expressly limited in this Agreement, to exercise, in person or by nominees or
proxies of the Trustees, all shareholders' voting rights and powers in respect
to all shares deposited hereunder, for any and every purpose, and to take part
in or consent to any corporate or stockholders' action of any kind whatsoever,
as absolute owner of such shares.  The Shareholders have hereby assigned to
Trustees all voting rights that they otherwise might have had arising out of any
ownership of the shares, whether by operation of law or agreement.  The right to
vote shall include the right to vote for or against or to abstain with respect
to the election of directors, and in favor of or against or to abstain with
respect to any resolution or proposed action of any character whatsoever, which
may be presented at any meeting or require the consent of shareholders of the
Company.  Without limiting such general right, it is understood that such action
or proceeding may include, upon terms satisfactory to the Trustees or to their
nominees or proxies thereto appointed by the Trustees, mortgaging, creating a
security interest in, and pledging of all or any part of the property of the
Company, the lease or sale of all or any part of the property of the Company,
for cash, securities, or other property, and the dissolution of the Company, or
the consolidation, merger, reorganization, or recapitalization of the Company.
It is further understood that action by the Trustees in voting or not voting
stock deposited hereunder in instances where there are shareholders' statutory
rights of appraisal may effectively waive or terminate any such rights as to the
shares represented thereby.

               (b) In voting the shares held by the Trustees hereunder either in
person or by nominees or proxies, the Trustees shall exercise their best
judgment in voting with respect to suitable directors and officers of the
Company (which may include the Trustees), or on such other matters as may be
voted on or consented to by the shareholders, including without limitation the
adequacy of any consideration to be received by the Company and its
shareholders, and shall otherwise, insofar as the Trustees may be shareholders
of the Company, take such part or action in respect to the management of the
Company's affairs as the Trustees may deem

                                      -10-
<PAGE>
 
necessary; and in voting upon any matters that may come before the Trustees at
any shareholders' meeting or otherwise, the Trustees shall exercise like
judgment, but the Trustees shall not be personally responsible with respect to
any action taken pursuant to the vote of the Trustees so cast in any matter or
act committed or omitted to be done under this Agreement, provided such
commission or omission does not amount to willful misconduct on the part of the
Trustees, and provided further that the Trustees at all times exercise good
faith in such matters.  In addition, the Shareholders, jointly and severally,
agree to indemnify and hold the Trustees harmless from any and all liabilities
resulting from actions taken pursuant to this Agreement, except only for acts
which constitute gross negligence or willful misconduct on the part of the
Trustees.  In the exercise of any and all of the rights of the Trustees under
this Agreement, the Trustees may choose at any time to waive any such exercise,
without the consent of any other party.

               (c) Meetings of the Trustees shall be held whenever either
Trustee desires. Notice stating the place and time of any meeting of the
Trustees shall be sufficient if given at least one day in advance of the time
fixed for the meeting, and notice may be given to the recipient either
personally, by telephone or by sending a copy thereof by first class or express
mail, postage prepaid, or by telex or TWX (with answerback received), or next
day courier service, charges prepaid, or by telecopier (with answerback
received), to such recipient's address (or to such recipient's telex, TWX,
telecopier or telephone number) appearing on the books of the Company or
supplied by such recipient to the Company for the purpose of notice. Any Trustee
may participate in any meeting of the Trustees, be counted for the purpose of
determining a quorum thereof and exercise all rights and privileges to which
such Trustee might be entitled were he personally in attendance, including the
right to vote, or any other rights attendant to presence in person at such
meeting, by means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other. So
long as there are two Trustees, both Trustees shall be necessary to constitute a
quorum for the transaction of business, and, subject to the next sentence, the
acts of both Trustees shall be the acts of the Trustees under this Agreement. If
the Trustees disagree as to how the shares held by them hereunder or any Proxy
Shares subject to a proxy hereunder should be voted, each Trustee shall vote 
one-half of the shares subject to this Agreement or such Proxy Shares, as
applicable, as he shall determine.

          11.  Trustees.
               -------- 

               (a) Any Trustee may at any time resign by mailing to the
registered holders of voting trust certificates and to any Proxy Shareholders a
written resignation, to take effect ten days thereafter or upon the prior
acceptance thereof. Upon the death of any Trustee or upon any Trustee's
adjudication of incompetence giving rise to the appointment of a custodian or
other representative, or upon a resignation of a Trustee, the remaining Trustee
shall act as sole Trustee during the remainder of the term of this Agreement,
and any act, decision, or vote by such Trustee shall be deemed the act,
decision, or vote of such Trustee. Upon the death, incompetence or resignation
of both Trustees, this Agreement shall terminate.

               (b) Upon one of the Trustees ceasing to serve as a Trustee as set
forth in subsection 11(a) above, the rights, powers, and privileges of the
Trustees named hereunder shall be possessed by the remaining Trustee, with the
same effect as though such remaining

                                      -11-
<PAGE>
 
Trustee had originally been the sole Trustee under this Agreement.  The word
"Trustees," as used in this Agreement, means the Trustees or at any time when
there is only one remaining Trustee, such Trustee acting hereunder, and shall
include both the single and the plural number.

          12.  Term.
               ---- 

               (a) Except as otherwise provided in subsection 10(a), this
Agreement shall continue in effect until June 23, 2007, (subject to extension as
hereinafter set forth) but shall terminate at any time upon the happening of
either of the following events: (1) the execution and acknowledgment by the
Trustees hereunder of a deed of termination, duly filed in the office of the
Company; or (2) such time as both Trustees have ceased serving as Trustees
pursuant to subsection 11(a).

               (b) At any time within one year prior to the expiration of this
Agreement as theretofore extended, the holders of all of the voting trust
certificates hereunder and any Proxy Shareholders at such time may, by agreement
in writing and with the written consent of the Trustees, extend the duration of
this Agreement for an additional period.  In the event of such extension, the
Trustees shall, prior to the time of expiration as hereinabove provided, as
originally fixed, or as theretofore extended, as the case may be, file in the
principal office of the Company, a copy of such extension agreement, and of the
consent thereto, and thereupon the duration of this Agreement shall be extended
for the period fixed by such extension agreement; provided, however, that no
such extension agreement shall extend the term of this Agreement beyond the
maximum period then permitted by applicable law or affect the rights, or
obligations of persons not parties thereto.

          13.  Compensation and Reimbursement of Trustees.  The Trustees shall
               ------------------------------------------                     
serve without compensation, unless such compensation is authorized by a majority
vote of the persons then holding voting trust certificates hereunder and Proxy
Shareholders representing at least seventy-five percent (75%) of the shares
represented by such voting trust certificates and Proxy Shares, but it is
expressly agreed that the Trustees shall have the right to incur and pay such
reasonable expenses and charges, to employ and pay such agents, attorneys, and
counsel as the Trustees may deem necessary and proper with respect to the
Trustees carrying out any of the Trustees' duties under this Agreement or
interpreting or exercising any of the Trustees' powers under this Agreement.
Any such expenses or charges incurred by and due to the Trustees paid by the
Company, where the Company deems it appropriate to its interests, may be
deducted pro rata from the dividends or other moneys or property received by the
Trustees on the stock deposited hereunder.  Nothing herein contained shall
disqualify the Trustees, or incapacitate either of them from serving the Company
or any of its subsidiaries as officer or director, or in any other capacity, and
in any such capacity receiving compensation.

          14.  Meetings of Holders.  The Trustees shall have no duty to hold
               -------------------                                          
meetings of holders of voting trust certificates, but the Trustees shall be
entitled to do so.  Two days written notice of every meeting of holders shall be
given and such notice shall state the place, day, hour and purposes of such
meeting, but any holder may waive such notice in writing, either before, during
or after the meeting.  No notice of any adjourned meeting need be given.  Every
such meeting shall be held within or without the Commonwealth of Pennsylvania at
a place designated by the Trustees.  The failure to hold meetings shall not in
any manner or degree

                                      -12-
<PAGE>
 
impair or reduce the authority of the Trustees hereunder.

          15.  Miscellaneous.
               ------------- 

               (a) Indulgences, Etc.  Neither the failure nor any delay on the 
                   ----------------                                   
part of any party to exercise any right, remedy, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any other right, remedy, power or privilege, nor
shall any waiver of any right, remedy, power or privilege with respect to any
occurrence be construed as a waiver of such right, remedy, power or privilege
with respect to any other occurrence.  No waiver shall be effective unless it is
in writing and is signed by the party asserted to have granted such waiver.

               (b) Controlling Law. This Agreement and all questions relating to
                   ---------------
its validity, interpretation, performance and enforcement (including, without
limitation, provisions concerning limitations of actions), shall be governed by
and construed in accordance with the laws of the Commonwealth of Pennsylvania,
notwithstanding any conflict-of-laws doctrines of such state or other
jurisdiction to the contrary, and without the aid of any canon, custom or rule
of law requiring construction against the draftsman.

               (c)  Notice.
                    ------ 

                    (i) Unless otherwise in this Agreement specifically
provided, any notice to or communication with the holders of the voting trust
certificates hereunder shall be deemed to be sufficiently given or made if
addressed to such holders at their respective addresses appearing on the
transfer books of the Trustees, postage prepaid and deposited in any post office
or post office box, personally delivered with evidence of receipt or submitted
to an overnight delivery service such as Federal Express or similarly recognized
service and so addressed. The addresses of the holders of voting trust
certificates, as shown on the transfer books of the Trustees, shall in all cases
be deemed to be the addresses of voting trust certificate holders for all
purposes under this Agreement, without regard to what other or different
addresses the Trustees may have for any voting trust certificate holder on any
other books or records of the Trustees. Every notice so given shall be
effective, whether or not received; and the date of mailing shall be the date
such notice is deemed given for all purposes.

                    (ii) Any notice of the Company hereunder shall be sufficient
if mailed with the U.S. Postal Service, postage prepaid, personally delivered
with evidence of receipt, or submitted to Federal Express or similarly
recognized overnight delivery service, to the Company addressed as follows:

                         Pierce Leahy Corp.
                         631 Park Avenue
                         King of Prussia, PA 19406

<PAGE>
 
                    (iii) Any notice to the Trustees hereunder shall be
sufficient if mailed with the U.S. Postal Service, postage prepaid, personally
delivered with evidence of receipt, or submitted to Federal Express or similarly
recognized overnight delivery service, to the Trustees, addressed to them at
such addresses as may from time to time be furnished in writing to the Company
by the Trustees, and if no such address has been so furnished by the Trustees,
then to the Trustees in care of the Company.

                    (iv) All distributions of cash, securities, or other
property hereunder by the Trustees to the holders of voting trust certificates
may be made, in the discretion of the Trustees, by mail, in the same manner as
hereinabove provided for the giving of notices to the holders of voting trust
certificates.

               (d) Binding Nature of Agreement; No Assignment. This Agreement
                   ------------------------------------------
shall be binding upon and inure to the benefit of the parties hereto, including
future holders of voting trust certificates, and their respective heirs,
personal representatives, successors and assigns. No party may sell, assign,
transfer or encumber such party's rights or obligations under this Agreement,
the voting trust certificates or the shares represented thereby, without the
prior written consent of the other parties hereto, except to the extent
expressly permitted in this Agreement; provided, however, upon the prior written
approval of the Trustees, a Shareholder or Proxy Shareholder may dispose of any
shares in a manner approved in writing by the Trustees. Neither the death,
disability nor incapacity of a holder of voting trust certificates shall in any
way remove the shares from being held by the Trustees under this Agreement.

               (e) Rights of Proxy Shareholders. Notwithstanding anything in
                   ----------------------------
this Agreement to the contrary, Proxy Shareholders beneficially owning Proxy
Shares shall have the same rights as Shareholders holding voting trust
certificates with respect to consenting to or voting upon matters as provided in
this Agreement.

               (f) Provisions Separable.  The provisions of this Agreement are
                   --------------------                                       
independent of and separable from each other, and no provision shall be affected
or rendered invalid or unenforceable by virtue of the fact that for any reason
any other or others of them may be invalid or unenforceable in whole or in part.

               (g) Entire Agreement.  This Agreement contains the entire
                   ----------------                                     
understanding between the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements and
understandings, inducements or conditions, express or implied, oral or written,
except as herein contained.  The express terms hereof control and supersede any
course of performance and/or usage of the trade inconsistent with any of the
terms hereof.  This Agreement may not be modified or amended other than by an
agreement in writing.

               (h) Paragraph Headings. The paragraph headings in this Agreement
                   ------------------
are for convenience only; they form no part of this Agreement and shall not
affect its interpretation.

               (i) Execution in Counterparts. This Agreement may be executed in
                   -------------------------
any number of counterparts, and shall become binding when one or more
counterparts hereof, individually taken together, shall bear the signatures of
all of the parties reflected hereon as the

                                      -14-

signatories.

               (j) Gender, Etc.  Words used herein, regardless of the number and
                   -----------                                                  
gender specifically used, shall be deemed and construed to include any other
number, singular or plural, and any other gender, masculine, feminine or neuter,
as the context indicates is appropriate.

               (k) Number of Days. In computing the number of days for purposes
                   --------------
of this Agreement, all days shall be counted, including Saturdays, Sundays and
holidays; provided, however, that if the final day of any time period (including
the effective date of a notice or other communication given hereunder) falls on
a Saturday, Sunday or holiday on which federal banks are or may elect to be
closed, then the final day shall be deemed to be the next day which is not a
Saturday, Sunday or such holiday.

                           NOTICE TO VOTING TRUSTEES



To the Trustees under that certain Amended and Restated Voting Trust Agreement
dated ________ __, 1998 (as such agreement may be amended, restated or extended
from time to time (the "Voting Trust Agreement)) among Pierce Leahy Corp., the
shareholders of the Company set forth on the signature pages thereof and Leo W.
Pierce, Sr. and J. Peter Pierce, in such persons' capacity as Voting Trustee
thereunder (the "Trustees").

Gentlemen:

          Notice is hereby given pursuant to Section 5(b) of the Voting Trust
Agreement that the undersigned shareholder requests to withdraw __________
shares (the "Margin Shares") from the Voting Trust in order to pledge such
shares to ______________________ as collateral for a margin account with such
broker.  Accompanying this Notice are voting trust certificates representing the
Margin Shares to be withdrawn, a letter from the broker indicating that such
shares are required for the margin account and a duly executed proxy in the form
attached as Exhibit C to the Voting Trust Agreement.  Please send to the
undersigned a certificate representing the Margin Shares, which the undersigned
understands will contain a restrictive legend under the Securities Act of 1933,
and a replacement voting trust certificate for any shares in the certificate
tendered herewith in excess of the number of Margin Shares.  The undersigned
acknowledges the requirement of Section 5(b) of the Voting Trust Agreement to
promptly redeliver any Margin Shares owned by the undersigned that are no longer
subject to the margin account.

                                    Very truly yours,



                                    ______________________________________

                                     PROXY


          This Irrevocable Proxy is granted this ____ day of _____________, ____
by the undersigned (the "Shareholder") pursuant to that certain Amended and
Restated Voting Trust Agreement dated _______ __, 1998 (as such agreement may be
amended or restated from time to time (the "Voting Trust Agreement)) among
Pierce Leahy Corp., the shareholders of the Company set forth on the signature
pages thereof and Leo W. Pierce, Sr. and J. Peter Pierce, in such persons'
capacity as Voting Trustee thereunder, to the Trustees (such term referring to
the Trustee or Trustees from time to time under the Voting Trust Agreement).

          The Shareholder irrevocably appoints the Trustees as his true and
lawful proxy with full power of substitution and resubstitution, to vote
__________ shares of the Common Stock of Pierce Leahy Corp., a Pennsylvania

telephonic notice, to be promptly confirmed in writing) 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 the US Administrative Agent shall promptly notify each US$ Lender
thereof.  All or any part of outstanding Eurodollar Loans and Base Rate Loans
may be converted as provided herein, provided that (i) no Base Rate 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 Required US$ Lenders have
determined that such a conversion is not appropriate and (ii) no Base Rate Loan
may be converted into a Eurodollar Loan after the date that is one month prior
to the Termination Date.

          (b)  Any Eurodollar Loans may be continued as such upon the expiration
of the then current Interest Period with respect thereto by the Company giving,
at least three Business Days' prior, irrevocable written or telephonic notice
(in the case of telephonic notice, to be promptly confirmed in writing) to the
US 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 the US Administrative Agent has or the Required US$ Lenders have
determined that such a continuation is not appropriate or (ii) after the date
that is one month prior to the Termination Date in accordance with the terms
described above and provided, further, that if the Company shall fail to give
                    --------  -------                                        
such notice or if such continuation is not permitted such Loans shall be
automatically converted to Base Rate Loans on the last day of such then expiring

Interest Period.  Upon receipt of any notice given by the Company pursuant to
this subsection 2.3(b), the US Administrative Agent shall promptly notify each
US$ Lender thereof.

          2.4  Minimum Amounts and Maximum Number of Eurodollar Tranches.
               ---------------------------------------------------------  
Notwithstanding anything to the contrary in this Agreement, all borrowings,
payments, prepayments, 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 Eurodollar Tranche shall
be equal to US$1,000,000 or a whole multiple of US$100,000 in excess thereof.
More than one borrowing may occur on the same date, but in no event shall there
be more than five Eurodollar Tranches outstanding at any time.


                      SECTION 3.  THE CANADIAN COMMITMENTS

          3.1  The Canadian Commitments.  Subject to the terms and conditions
               ------------------------                                      
hereof, each C$ Lender severally agrees to make revolving credit loans (which
shall be C$ Prime Loans) to, and to accept and, at the option of the Canadian
Borrower, purchase Bankers' Acceptances from, the Canadian Borrower from time to
time during the Commitment Period in an aggregate principal amount at any one
time outstanding not to exceed such Lender's Canadian Commitment.  During the
Commitment Period, the Canadian Borrower may use the Canadian Commitments by
borrowing, prepaying or repaying the C$ Prime Loans or Bankers' Acceptances, in
whole or in part, and reborrowing, all in accordance with the terms and
conditions hereof.

          3.2  Procedure for C$ Loan Borrowing.  The Canadian Borrower may
               -------------------------------                            
borrow C$ Prime Loans during the Commitment Period on any Business Day, provided
                                                                        --------
that the Canadian Borrower shall give the Canadian Administrative Agent
irrevocable written or telephonic notice (in the case of telephonic notice, to
be promptly confirmed in writing) (which notice must be received by the Canadian
Administrative Agent prior to 10:00 A.M., Toronto time, one Business Day prior
to the requested Borrowing Date), specifying (a) the amount to be borrowed and
(b) the requested Borrowing Date.  Each borrowing of C$ Prime Loans shall be in
an amount equal to C$300,000 or a whole multiple of C$100,000 in excess thereof.
Upon receipt of any such irrevocable notice from the Canadian Borrower, the
Canadian Administrative Agent shall promptly notify each C$ Lender thereof.
Each C$ Lender will make the amount of its pro rata share of each such borrowing
available to the Canadian Administrative Agent for the account of the Canadian
Borrower at the Canadian Administrative Office prior to 11:00 A.M., Toronto
time, on the Borrowing Date requested by the Canadian Borrower in funds
immediately available to the Canadian Administrative Agent.  Such borrowing will
then be made available on such Borrowing Date to the Canadian Borrower by the
Canadian Administrative Agent 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 C$ Lenders
and in like funds as received by the Canadian Administrative Agent.

          3.3  Bankers' Acceptances.  (a)  The Canadian Borrower may issue
               --------------------                                       
Bankers' Acceptances denominated in C$, for acceptance and, at the Canadian
Borrower's option, purchase by the C$ Lenders, each in accordance with the
provisions of this subsection 3.3.

          (b)  Procedures.
               ---------- 

          (1)  Notice.  The Canadian Borrower shall notify the Canadian
               ------                                                  
     Administrative Agent by irrevocable written or telephonic notice (in the
     case of telephonic notice, to be promptly confirmed in writing) 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 Borrowing Amount.  Each borrowing by way of Bankers'
               ------------------------                                    
     Acceptances shall be in a minimum aggregate face amount of C$1,000,000 or a
     whole multiple of C$100,000 in excess thereof.

          (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 C$ Lenders), shall mature on or before the Termination Date and shall
     be in form and substance reasonably satisfactory to each C$ 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 the Canadian Administrative Agent
     Drafts duly executed and endorsed in blank by the Canadian Borrower in
     quantities sufficient for each C$ Lender to fulfill its obligations
     hereunder.  Each C$ Lender is hereby authorized to accept such Drafts
     endorsed in blank in such face amounts as may be determined by such C$
     Lender in accordance with the terms of this Agreement, provided that the
                                                            --------         
     aggregate amount thereof is less than or equal to the aggregate amount of
     Bankers' Acceptances required to be accepted by such C$ Lender.  No C$
     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 C$ 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 C$ Lender, its officers, employees, agents or
     representatives.  The Canadian Administrative Agent and each C$ 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 C$ Lender will, upon the request of the Canadian Borrower,
     promptly advise the Canadian Borrower of the number and designation, if
     any, of Drafts then held by it for the Canadian Borrower.  Each C$ Lender
     shall

                                                                              32

     maintain a record with respect to Drafts and Bankers' Acceptances (i)
     received by it from the Canadian Administrative Agent 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 C$ 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 C$ 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 C$ Lenders and shall advise each
     C$ Lender of the face amount of each Draft to be accepted by it and the
     term thereof.  The aggregate face amount of Drafts to be accepted by a C$
     Lender shall be determined by the Canadian Administrative Agent on a pro
     rata basis by reference to the respective Canadian Commitments of the C$
     Lenders, except that, if the face amount of a Draft which would otherwise
     be accepted by a C$ 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 C$ Lender shall be accepted at such C$ Lender's Canadian Lending Office.

          (9)  Purchase of Bankers' Acceptances.  Each C$ 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 C$ Lender under subsection 3.3(e) in respect of each Bankers'
     Acceptance accepted and purchased by such C$ Lender from the Canadian
     Borrower shall be set off against the BA Discount Proceeds payable by such
     C$ Lender under this subsection 3.3(b)(9).  Not later than 2:00 P.M.,
     Toronto time, on such Borrowing Date, the Canadian Administrative Agent
     shall 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
<PAGE>
 
                                                                              33

     made available to the Canadian Administrative Agent by the C$ Lenders and
     in like funds as received by the Canadian Administrative Agent.

          (10)  Sale of Bankers' Acceptances.  Each C$ 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 C$ 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 C$ Lender in its own right,
     and the Canadian Borrower agrees not to claim any days of grace if such C$
     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 a C$ Lender for, and there
shall become due and payable at 10:00 A.M., Toronto time, on the contract
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 a Refunding Bankers' Acceptance issued in accordance with subsection
3.3(d) or conversion of such Bankers' Acceptance in accordance with subsection
3.4 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 application of any proceeds referred to in clause (i))
with the Canadian Administrative Office in accordance with subsection 4.8.  The
Canadian Borrower's payment in accordance with this Section shall satisfy its
obligations under any Bankers' Acceptance to which it relates, and the C$ 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 or
telephonic notice (in the case of telephonic notice, to be promptly confirmed in
writing) (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 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 C$ 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 have sufficient funds on deposit in the amount of
reimbursement payment in accordance with subsection 3.3(c)(ii), the Canadian
Borrower shall be deemed to have requested that such maturing Bankers'
Acceptances be repaid with

                                                                              34

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 C$ Lender in advance (in the manner specified in subsection 3.3(b)(9)) upon
the issuance of a Bankers' Acceptance to be accepted by such C$ 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 C$ Lender and the
Canadian Administrative Agent hereunder, any C$ Lender or the Canadian
Administrative Agent (or such alternate arrangement as may be agreed upon by the
Canadian Borrower and such C$ 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
C$ Lenders, amounts which are received by such C$ Lender or the Canadian
Administrative Agent from the Canadian Borrower hereunder or as proceeds of the
exercise of any rights or remedies of any C$ 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 C$ Lenders or the Canadian
Administrative Agent, or any of them hereunder.

          3.4  Conversion Option.  Subject to the provisions of this Agreement,
               -----------------                                               
the Canadian Borrower may, prior to the 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 written or telephonic notice (in the case of telephonic notice, to
be promptly confirmed in writing) 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 C$ Loan into which the outstanding C$ Loan is to be converted in
accordance with the provisions of subsection 3.2 or 3.3, as applicable, provided
                                                                        --------
that:

          (a)   no C$ Prime Loan may be converted into a Bankers' Acceptance
          when any Event of Default has occurred and is continuing;

          (b)   each conversion to Bankers' Acceptances shall be for an
          aggregate amount of C$1,000,000 (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$100,000; 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$1,000,000 (and whole
<PAGE>
 
                                                                              35

          multiples of C$100,000 in excess thereof) shall remain as Bankers'
          Acceptances.

          3.5  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, 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 Loans (all as if it were a notice given
     pursuant to subsection 3.2).

          (b)  The Canadian Administrative Agent shall promptly notify the
Canadian Borrower and the C$ 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 4.  GENERAL PROVISIONS

          4.1  Repayment of Loans; Evidence of Debt.  (a) The Company hereby

          (b) The Canadian Borrower hereby unconditionally promises to pay to
the Canadian Administrative Agent for the account of each C$ Lender the then

the date hereof until payment in full thereof at the rates per annum, and on the
dates, set forth in subsection 4.5.

          (c)  Each Lender shall maintain in accordance with its usual practice

          (c)  The Company shall have the right, upon not less than two Business
Days' notice to the applicable Administrative Agent, without premium or penalty,
to terminate the Commitments or, from time to time, to reduce the amount of the
US Commitments (so long as, after giving effect thereto and to any
contemporaneous prepayment of the Loans, the then outstanding US$ Loans of each
US$ Lender shall be no greater than such Lender's US Commitment) or reduce the
amount of the Canadian Commitments (so long as, after giving effect thereto and
to any contemporaneous prepayment of the C$ Loans, the then outstanding C$ Loans
of each C$ Lender shall be no greater than such Lender's Canadian Commitment).
Upon receipt of such notice the applicable Administrative Agent shall promptly
notify each relevant Lender thereof.  Any such reduction shall be in an amount
of at least US$500,000 and, if greater, in integral multiples of US$100,000 (in
the case of the US Commitments) or C$500,000 and, if greater, in integral
multiples of C$100,000 (in the case of the Canadian Commitments) and shall
reduce permanently the amount of the affected Commitments then in effect.  Any
termination of the Commitments shall be accompanied by prepayment in full of the
Loans, together with accrued interest thereon to the date of such prepayment.

          4.4  Optional and Mandatory Prepayments.  (a)  Each Borrower may at

without premium or penalty, upon at least three Business Days' irrevocable
notice to the relevant Administrative Agent (in the case of Eurodollar Loans),
or one Business Day's irrevocable notice to the relevant Administrative Agent
(otherwise), specifying the date and amount of prepayment, and the Type of Loan
to be prepaid, and, if of a combination thereof, the amount allocable to each.
Upon receipt of any such notice the relevant Administrative Agent shall promptly
notify each relevant Lender 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, in the case of Eurodollar Loans, any interest accrued thereon,
and in the case of all Loans, any amounts payable pursuant to subsection 4.12.
Partial prepayments shall be in an aggregate principal amount of US$1,000,000 or
C$1,000,000, as the case may be, or a whole multiple of US$100,000 or C$100,000,
as the case may be, in excess thereof.

Notwithstanding anything to the contrary above, C$ Loans consisting of Bankers'
Acceptances may not be prepaid pursuant to this subsection.

subsection 4.4(b), but excluding any Reinvestable Proceeds (as defined below),
shall exceed US$2,500,000 then, no later than five Business Days after the
occurrence of the Current Disposition, the relevant Borrower will deliver to the
US Administrative Agent a statement, certified by a Responsible Officer of such
Borrower, in form and detail reasonably satisfactory to the US Administrative
Agent, of the amount of the Net Proceeds of the Current Disposition and of all
such prior Dispositions and shall prepay its Loans, and its Commitments shall be
subject to automatic reduction (and, if required, such Borrower shall provide
cash collateral in connection with such reduction, which cash collateral shall
be invested in Cash Equivalents), in an aggregate amount equal to the excess of
100% of the Net Proceeds of the Current Disposition and such prior Dispositions
(but excluding the amount of any Reinvestable Proceeds) over US$2,500,000 (or

of Default shall have occurred and be continuing or would be caused thereby and
subject to the consent of the Required Lenders in connection with any
Disposition not otherwise permitted hereunder, such Net Proceeds shall not be
required to be applied on such date so long as such Borrower delivers a
certificate of a Responsible Officer to the US Administrative Agent prior to
such date stating that such Borrower intends to use all or a portion of the Net
Proceeds of any Disposition (the "Reinvestable Proceeds" of such Disposition) to

such election to use the Reinvestable Proceeds, on the date which is 270 days
after the relevant Disposition, such Borrower shall (I) deliver a certificate of
a Responsible Officer to the US Administrative Agent certifying as to the amount
and use of such Reinvestable Proceeds actually used to purchase Qualified Assets
and (II) deliver to the US Administrative Agent, for application in accordance
with this subsection 4.4(b), an amount equal to the remaining unused
Reinvestable Proceeds.

          (c)  On the date of the receipt thereof by either Borrower or any of
its Subsidiaries, such Borrower shall prepay its Loans (but the Commitments
shall not be subject to any reduction) in an aggregate amount equal to (i) 100%
of the proceeds (net of underwriting discounts and commissions and other costs
associated therewith) from any sale or issuance of equity of such Borrower or
any of its Subsidiaries (other than any portion of such proceeds applied to
redeem 1997 Senior Subordinated Notes as permitted by subsection 8.11(a)) other
than to either Borrower or any of its Subsidiaries and (ii) 100% of the proceeds
(net of underwriting discounts and commissions and other costs associated
therewith) from any incurrence of any Indebtedness for borrowed money by such
Borrower or any of its

Subsidiaries (other than Indebtedness permitted by subsection 8.4), such
prepayment to be effected in each case in the manner and order specified in
subsection 4.4(g).  The provisions of this paragraph shall not limit the
obligation of the Company to obtain the consent of the Required Lenders to any
action referred to in this paragraph that is not otherwise permitted hereunder.

          (d)  In the event that the Net Proceeds of any Casualty Event of
either Borrower or any of its Subsidiaries (the "Current Casualty Event"), and

US$2,500,000, then, no later than five Business Days after the occurrence of the
Current Casualty Event, the relevant Borrower will deliver to the US
Administrative Agent a statement, certified by a Responsible Officer of such
Borrower, in form and detail reasonably satisfactory to the relevant
Administrative Agent, of the amount of the Net Proceeds of the Current Casualty
Event and of all such prior Casualty Events and shall prepay its Loans, and its
Commitments shall be subject to automatic reduction (and, if required, such
Borrower shall provide cash collateral in connection with such reduction, which
cash collateral shall be invested in Cash Equivalents), in an aggregate amount
equal to the excess of 100% of the Net Proceeds of the Current Casualty Event
and such prior Casualty Events (but excluding the amount of any Casualty
Reinvestable Proceeds) over US$2,500,000 (or the C$ Equivalent thereof, as the
case may be), such prepayment and reduction to be effected in each case in the
manner and order specified in subsection 4.4(g); provided, that such Net

Proceeds shall not be required to be applied on such date (other than if such
Net Proceeds are required to be applied pursuant to the terms of any Mortgage or
lease) so long as (i) such Borrower delivers a certificate of a Responsible
Officer to the US Administrative Agent prior to such date stating that such
Borrower intends to use or cause the appropriate Subsidiary to use such Net
Proceeds (the "Casualty Reinvestable Proceeds" of such Casualty Event) to repair

Property") within 270 days after receipt of such Net Proceeds and setting forth
an estimate of the Casualty Reinvestable Proceeds to be so expended and (ii) no
Event of Default shall have occurred and be continuing or would be caused
thereby.  After such election to reinvest, on the date which is 270 days after
the relevant Casualty Event, such Borrower shall (I) deliver a certificate of a
Responsible Officer to the relevant Administrative Agent certifying as to the
amount and use of such Casualty Reinvestable Proceeds actually used to purchase
or replace the Affected Property and (II) deliver to the relevant Administrative
Agent, for application in accordance with this subsection 4.4(d), an amount
equal to the remaining unused Casualty Reinvestable Proceeds.

          (e)  On the date of the receipt thereof by either Borrower or any of
its Subsidiaries, such Borrower shall prepay its Loans (but its Commitments
shall not be subject to any reduction) in an aggregate amount equal to 100% of
the proceeds of any Tax Refund (net of any marginal increase in income taxes
payable as a result of the receipt by such Borrower and/or any of its
Subsidiaries of such Tax Refund, such prepayment to be effected in each case in

          (f)  On the date of the receipt thereof by either Borrower or any of
its Subsidiaries, such Borrower shall prepay its Loans (but its Commitments
shall not be subject to any reduction) in an aggregate amount equal to 100% of
the Net Proceeds of any Disposition of property acquired as part of a Permitted
Acquisition but not used or useful to the business of such Borrower or such
Subsidiary so long as such Disposition is made within 270 days of the date of
the consummation of such Permitted Acquisition, such prepayment to be effected
in each case in the manner and order specified in subsection 4.4(g).

          (g)  Prepayments of the Loans pursuant to subsections 4.4(b), (c),
(d), (e) and (f) and permanent reductions of Commitments pursuant to subsections
4.4(b) and (d) shall be applied in the following manner:

          (i)  to the extent such prepayment is required to be made by the
     Company, such prepayment shall be applied to reduce (ratably among the US
     Lenders) such of the then outstanding US$ Loans as the Company shall
     determine in its sole discretion, and any reduction of the Commitments
     required pursuant thereto shall be applied ratably to reduce the US
     Commitments (which reduction of US Commitments shall reduce the remaining
     scheduled commitment reductions thereof in inverse order of maturity); and

          (ii)  to the extent that such prepayment is required to be made by the
     Canadian Borrower, such prepayment shall be applied to reduce (ratably
     among the Canadian Lenders) such of the then outstanding C$ Loans (or, in
     the case of Bankers' Acceptances, cash collateralization of such Bankers'
     Acceptances on terms satisfactory to the Canadian Administrative Agent,
     which cash collateral shall be invested in Cash Equivalents) as the
     Canadian Borrower shall determine in its sole discretion, and any reduction
     of the Canadian Commitments required pursuant thereto shall be applied
     ratably to reduce the Canadian Commitments (which reduction of Canadian
     Commitments shall reduce the remaining scheduled commitment reductions
     thereof in inverse order of maturity).

          (h)  Notwithstanding anything to the contrary contained above, all
prepayments of each Loan shall be made in the currency in which such Loans were
made, and all cash collateralization of Bankers Acceptances shall be made in
Canadian 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 or Bankers
Acceptances maintained in the other such currency.

          4.5  Interest Rates and Payment Dates.  (a)  Each Eurodollar Loan
               --------------------------------                            
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such
Interest Period plus the Applicable Margin.
<PAGE>
 
                                                                              42

          (b) Each Base Rate Loan shall bear interest for each day on the unpaid
principal amount thereof, at a rate per annum equal to the Base Rate determined
for such day plus the Applicable Margin.

          (c)  Each C$ Prime Loan shall bear interest for each day on the unpaid
principal amount thereof, at a rate per annum equal to the C$ Prime Rate
determined for such day plus the Applicable Margin.

          (d)  If all or a portion of (i) any principal of any Loan, (ii) any
interest payable thereon, (iii) any Acceptance Fee or any commitment fee or (iv)
any other amount payable hereunder shall not be paid when due (whether at the
stated maturity, by acceleration or otherwise), such overdue amount shall bear
interest at a rate per annum which is (x) in the case of principal, the rate
that would otherwise be applicable thereto pursuant to the foregoing provisions
of this subsection plus 2% or (y) in the case of any such overdue interest,
Acceptance Fee or commitment fee or other amount, the rate described in
paragraph (b) of this subsection (in the case of amounts payable in US Dollars)
or paragraph (c) of this subsection (in the case of amounts payable in Canadian
Dollars) plus 2%, in each case from the date of such non-payment until such
overdue principal, interest, Acceptance Fee or commitment fee or other amount is
paid in full (after as well as before judgment).

          (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 C$ 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 C$ Lender
in an amount or calculated at a rate which would be prohibited by law or would
result in a receipt by such C$ 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 C$
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 4.5; 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 4.5.(f), and after giving effect to all adjustments contemplated
thereby, any C$ 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 C$ Lender, to obtain reimbursement
<PAGE>
 
                                                                              43

from such C$ Lender of an amount equal to such excess, and, pending such
reimbursement, such amount shall be deemed to be an amount payable by such C$
Lender to such Loan Party.

          (iii)  Any amount or rate of interest referred to in this subsection
4.5(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 C$ 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
Termination Date 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.

          4.6  Computation of Interest and Fees.  (a)  Interest calculated on
               --------------------------------                              
the basis of the Eurodollar Rate and Federal Funds Rate shall be calculated on
the basis of a 360-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; and
interest calculated on any other basis shall be calculated on the basis of a
365- or 366- day year, as the case may be, for the actual days elapsed.  The
relevant Administrative Agent shall as soon as practicable notify the relevant
Borrower and the relevant Lenders of each determination of Eurodollar Rates or
the Applicable BA Discount Rate.  Any change in the interest rate on a Loan
resulting from a change in the Base Rate, the C$ Prime Rate or the Applicable
Margin 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 Lenders and the relevant Borrower of the
effective date and the amount of each such change in interest rate.

          (b)  Each determination of an interest rate by the relevant
Administrative Agent pursuant to any provision of this Agreement shall be prima
facie evidence of the accuracy thereof on the Borrowers and the Lenders in the
absence of manifest error.  When applicable, each determination by CIBC of a
rate to be notified to the relevant Administrative Agent pursuant to the
definition of "CDOR Rate" shall be prima facie evidence of the accuracy thereof.
The relevant Administrative Agent shall, at the request of the relevant
Borrower, deliver to such Borrower a statement showing any quotations and the
computations used by the relevant Administrative Agent in determining any CDOR
Rate.

          (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
principles of deemed investment of interest do 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 Eurodollar Rate.  If prior to the first
               --------------------------------------                        
day of any Interest Period:

          (a)  the US Administrative Agent shall have determined (which
     determination shall be prima facie evidence of the accuracy thereof) 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
     Required US$ 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 (to be
confirmed in writing) thereof to the Company 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
Base Rate Loans, (y) any Base Rate 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 Base Rate Loans and (z) any outstanding Eurodollar Loans shall be
converted, on the first day of such Interest Period, to Base Rate 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 the Company have
the right to convert Loans to Eurodollar Loans.

          4.8  Pro Rata Treatment and Payments.  (a)  Each borrowing by each
               -------------------------------                              
Borrower from the Lenders hereunder, each payment by each Borrower on account of
any commitment fee or Acceptance Fee hereunder and any reduction of the US
Commitments or the Canadian Commitments of the Lenders shall be made pro rata
according to the respective US Commitment Percentages, in the case of the US$
Lenders, and the respective C$ Commitment Percentages, in the case of the C$
Lenders.  Each payment (excluding prepayments pursuant to subsection 4.4(g)) by
each Borrower on account of principal of and interest on the Loans shall be made
pro rata according to the respective outstanding principal amounts of the
relevant Loans then held by the relevant Lenders.  All payments (including
prepayments) to be made by each Borrower hereunder, whether on account of
principal, interest, fees or otherwise, shall be made without set off or
counterclaim and shall be made prior to 11:00 A.M., Local Time, on the due date
thereof to the relevant Administrative Agent, for the account of the Lenders, at
the relevant Administrative Office, in US$ or C$, as the case may be, and in
immediately available funds.  The relevant Administrative Agent shall distribute
such payments to the relevant Lenders promptly upon receipt in like funds as
received, but the relevant Borrower shall have satisfied its payment obligation
hereunder upon payment to the relevant Administrative Agent, regardless of
whether such Administrative Agent distributes such payments as required
hereunder.  If any payment hereunder becomes due and payable on a day other than
a Business Day, 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.
<PAGE>
 
                                                                              45

          (b)  Unless the relevant Administrative Agent shall have received
notice from a Lender prior to 11:00 A.M., Local Time, on any Borrowing Date that
such Lender will not make available to such Administrative Agent such Lender's
share of the borrowing requested to be made on such Borrowing Date, such
Administrative Agent may assume that such Lender has made its share of such
borrowing available to such Administrative Agent on such Borrowing Date, and
such Administrative Agent may, in reliance upon such assumption, make available
to the relevant Borrower on such Borrowing Date a corresponding amount.  If such
Administrative Agent does, in such circumstances, make available to such
Borrower such amount, such Lender shall within three Business Days following
such Borrowing Date make its share of such borrowing available to such
Administrative Agent, together with interest thereon for each day from and
including such Borrowing Date that its share of such borrowing was not made
available, to but excluding the date such Lender makes its share of such
borrowing available to such Administrative Agent, at the Federal Funds Rate (in
the case of US$ Loans) or at the then effective CDOR Rate (in the case of C$
Loans).  If such amount is so made available, such payment to such
Administrative Agent shall constitute such Lender's Loan on such Borrowing Date
for all purposes of this Agreement.  A certificate of such Administrative Agent
submitted to any Lender with respect to any amounts owing under this subsection
shall be prima facie evidence of such amounts.  If such amount is not so made
available to such Administrative Agent by such Lender within three Business Days
of such Borrowing Date, such Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Base Rate Loans hereunder, on demand, from the relevant Lender.  Nothing
contained in this subsection 4.8(b) shall relieve any Lender which has failed to
make available its share of any borrowing hereunder from its obligation to do so
in accordance with the terms hereof or prejudice any rights which the relevant
Borrower may have against any Lender as a result of any default by such Lender
to make loans.

          (c)  The failure of any Lender to make the Loan to be made by it on
any Borrowing Date shall not relieve any other Lender of its obligation, if any,
hereunder to make its Loan on such Borrowing Date, but no Lender shall be
responsible for the failure of any other Lender to make the Loan to be made by
such other Lender on such Borrowing Date.

          4.9  Illegality.  Notwithstanding any other provision herein, if the
               ----------                                                     
adoption of or any change in any Requirement of Law or 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 Base Rate 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 Base Rate 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 Company shall pay to such Lender such amounts, if any, as
may be required pursuant to subsection 4.12.

          4.10  Requirements of Law.  (a)  If the adoption of or any change in
                -------------------                                           
any Requirement of Law or 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, or cause the withdrawal or
     termination of a previously granted exemption with respect to, any tax of
     any kind whatsoever, or change the basis of taxation of, or increase any
     existing tax on, payments of principal, interest, fees or other amounts
     payable by either Borrower to such Lender under this Agreement (except for
     taxes on the overall receipts or overall net income or capital of such
     Lender, and any related surtaxes, or taxes for which such Lender is being
     fully compensated under subsection 4.11);

               (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 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 to reduce any amount receivable
hereunder in respect thereof, then, in any such case, the relevant Borrower
shall promptly pay such Lender, upon written demand therefor, such additional
amount or amounts as will compensate such Lender for such increased cost or
reduced amount receivable; provided, that such Borrower shall not be required to
                           --------                                             
pay any Lender any such additional amount if such additional amount arises (x)
in the case of US$ Loans made to the Company, as a consequence of such Lender's
failure to meet the requirements of subsection 4.11(b) or (y) in the case of C$
Loans made to the Canadian Borrower, as a result of such Lender's failure to be
a Person resident in Canada for the purposes of the Income Tax Act (Canada).
                                                    --------------          

          (b)  If the adoption of or any change in any Requirement of Law
regarding capital adequacy or in the interpretation or application thereof by
any Governmental Authority or compliance by any 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 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 to a level below that which such Lender or such
corporation could have achieved but for such adoption, 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, the Borrowers shall promptly pay to such Lender, upon
written demand therefor, such additional amount or amounts as will compensate
such Lender for such reduced rate of return.  In determining such additional
amounts, each Lender will act reasonably and in good faith and will use
averaging and attribution methods which are reasonable and which will, to the
extent the reduced rate of return relates to such Lender's loans or commitments
in general and are not specifically
<PAGE>
 
                                                                              47

attributable to Loans or Commitments hereunder, be calculated with respect to
all loans or commitments similar to the Loans or Commitments made by such Lender
hereunder whether or not the loan documentation for such other loans or
commitments permits the Lender to charge the respective borrower on a basis
similar to that provided in this subsection 4.10.

          (c)  If any Lender becomes entitled to claim any additional amounts
pursuant to this subsection, it shall promptly notify the relevant Borrower
(with a copy to 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 to such Borrower
(with a copy to the relevant Administrative Agent), showing in reasonable detail
the basis for the calculation thereof, shall be prima facie evidence of such
additional amounts payable.  The agreements in this subsection shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

          4.11  Taxes.  (a)  All payments made by any Loan Party under this
                -----                                                      
Agreement and any Notes 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 gross or net income or gross receipts taxes,
ad valorem taxes, personal property and/or sales 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 either
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 such
Administrative Agent or such Lender having executed, delivered or performed its
obligations or received a payment under, or enforced, this Agreement or any
Note).  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, the amounts so payable to such 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, provided, however, that no Loan Party shall
                                     --------  -------                          
be required to increase any such amounts payable to either Administrative Agent,
any Lender or any holder of Bankers' Acceptances 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 any Canadian Borrower with respect to C$ Loans, the
failure of such C$ Lender, the Canadian Administrative Agent or any holder of
Bankers' Acceptances to be a Person resident in Canada for the purposes of the
                                                                              
Income Tax Act (Canada).  Each Loan Party 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
<PAGE>
 
                                                                              48

4.11(a).  Whenever any Non-Excluded Taxes are payable by any Loan Party, as
promptly as possible thereafter but in any event within 45 days after the date
of payment such Loan Party 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 Loan Party
showing payment thereof.  If any Loan Party 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 Loan Party shall indemnify such 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:

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

               (ii)  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

               (iii)  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;

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 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 of Eurodollar
Loans after such Borrower has given a notice thereof in accordance with the
provisions of this Agreement, (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 or
(d) repayment of any Bankers' Acceptance prior to its maturity date.  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.

          4.13  Change of Lending Office.  Each Lender agrees that if it makes
                ------------------------                                      
any demand for payment under subsection 4.10 or 4.11(a), or if any adoption or
change of the type described in subsection 4.9 shall occur with respect to it,
it will use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions and so long as such efforts would not be
disadvantageous to it, as determined in its sole discretion) to designate a
different lending office if the making of such a designation would reduce or
obviate the need for the Company to make payments under subsection 4.10 or
4.11(a), or would eliminate or reduce the effect of any adoption or change
described in subsection 4.9.


                   SECTION 5.  REPRESENTATIONS AND WARRANTIES

          To induce the Administrative Agents and the Lenders to enter into this
Agreement and to make the Loans, the Company hereby represents and warrants to
the Administrative Agents and each Lender that:

          5.1  Financial Condition.  The consolidated balance sheet of the
               -------------------                                        
Company and its consolidated Subsidiaries as at December 31, 1996 and the
related consolidated statements of income and retained earnings and changes in
cash flows for the fiscal year ended on such date, reported on by Arthur
Andersen LLP, copies of which have heretofore been furnished to each Lender, are
complete and correct and present fairly in accordance with GAAP the consolidated
financial position of the Company and its consolidated Subsidiaries as at such

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

limitation, any interest rate or foreign currency swap or exchange transaction,
which is not reflected in the foregoing statements or in the notes thereto.

its consolidated Subsidiaries at December 31, 1996.

qualified could not 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.  Each of

enforceability thereof may be limited by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) and an implied covenant of good
faith and fair dealing.

               ------------                                                 
Loan Documents to which each Loan Party is a party, the borrowings hereunder and
the use of the proceeds thereof will not violate any Requirement of Law or
Contractual Obligation of such Loan Party or of any of its Subsidiaries and will
not result in, or require, the creation or imposition of any Lien (except
pursuant to the Loan Documents to which it is a party) on any of its or their
respective properties or revenues pursuant to any such Requirement of Law or
Contractual Obligation.

          5.6  No Material Litigation.  No litigation, investigation or
               ----------------------                                  
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrowers, threatened by or against either Borrower or
any of its Subsidiaries or against any of its or their respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) which could reasonably be
expected to have a Material Adverse Effect.

          5.7  No Default.  Neither Borrower nor any of its Subsidiaries is in
               ----------

respect which could reasonably be expected to have a Material Adverse Effect.
No Default or Event of Default has occurred and is continuing.

          5.8  Ownership of Property; Liens.  All real property owned or leased
               ----------------------------                                    
by either Borrower or any of its Subsidiaries and the nature of the interest
therein, is correctly set forth on Schedule 5.8.  The Company and its
Subsidiaries have good and valid title to all real property owned by them and
good and merchantable title to all other properties owned by them, in each case,
including all property reflected in the balance sheets referred to in subsection

          5.9  Intellectual Property.  The Company and each of its Subsidiaries
               ---------------------                                           
owns, or is licensed to use, all trademarks, tradenames, copyrights, technology,
know-how and processes necessary for the conduct of its business as currently
conducted except for those the failure to own or license which could not
reasonably be expected to have a Material Adverse Effect (the "Intellectual

Property").  Neither the Company nor any of its Subsidiaries has any knowledge
- --------                                                                      
that any claim has been asserted and is pending by any Person challenging or
questioning the use of any such Intellectual Property or the validity or
effectiveness of any such Intellectual Property, nor does the Company know of
any valid basis for any such claim.  The use of such Intellectual Property by
the Company and its Subsidiaries does not infringe on the rights of any Person,
except for such claims and infringements that, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

          5.10  No Burdensome Restrictions.  No Requirement of Law or
                --------------------------                           
Contractual Obligation of either Borrower or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

          5.11  Taxes.  Each of the Company and its Subsidiaries has filed or
                -----                                                        
caused to be filed all tax returns which, to the knowledge of the Company, are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its property and all
other taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than as set forth on Schedule 5.11 and any the
amount or validity of which are currently being contested in good faith by
appropriate proceedings and with respect to which reserves in conformity with
GAAP have been provided on the books of the Company or its Subsidiaries, as the
case may be); no tax Lien has been filed, and, to the knowledge of the Company,
no claim is being asserted, with respect to any such tax, fee or other charge.

          5.12  Margin Regulations.  No part of the proceeds of any Loans will
                ------------------                                            
be used to purchase or carry any Margin Stock (as defined in Regulation G, T, U
or X) or to extend credit for the purpose of purchasing or carrying any Margin
Stock.  Neither the making of any Loan, the creation of any Bankers Acceptance
or the purchase of any Draft nor the use of the proceeds thereof will violate or
be inconsistent with the provisions of Regulation G, T, U or X of the Board of
Governors of the Federal Reserve System.

          5.13  ERISA; Canadian Pension Plans.  (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 Plan, and each Plan has complied in all material respects with the
applicable provisions of ERISA and the Code.  No termination of a Single
Employer Plan has occurred, and no Lien 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
<PAGE>
 
                                                                              53

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 in which it participates 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 or Insolvent.

          (b)  Each Canadian Pension Plan is in substantial compliance with all
applicable pension benefits and tax laws; 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 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 result in the Company or any Subsidiary of the Company
being required to pay, repay or refund any amount (other than contributions
required to be 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
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).

meaning of the Investment Company Act of 1940, as amended.  No Loan Party is
subject to regulation under any federal or state statute or regulation (other
than Regulation X of the Board of Governors of the Federal Reserve System) which
limits its ability to incur Indebtedness.

the Company or any of its Subsidiaries that could reasonably be expected (i) to
form the basis of an Environmental Claim against the Company or any of its
Subsidiaries which could reasonably be expected to have a Material Adverse
Effect, or (ii) in the case of real property owned or operated by the Company or
any of its Subsidiaries, to cause such real property to be subject to any

                     SECTION 10.  THE ADMINISTRATIVE AGENTS

          10.1  Appointment.  Each Lender hereby irrevocably designates and
                -----------                                                
appoints the Administrative Agents as the agents of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes the Administrative Agents, in such capacities, 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 in this Agreement, or any fiduciary relationship with
any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against either Administrative Agent.  The Borrowers
shall be entitled to conclusively rely upon any statement made by either
Administrative Agent that it has received the approval of the Required Lenders,
the Required US$ Lenders, the Required C$ Lenders, all of the Lenders, all of
the US$ Lenders or all of the C$ Lenders.

          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 to any Lender 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 nor 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 such 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 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
<PAGE>
 
                                                                              83

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 any Loan
Party.

          10.4  Reliance by Administrative Agent.  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 reasonably 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
Borrowers), independent accountants and other experts selected by the
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 such
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
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction 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 other Loan Documents in
accordance with a request of the Required 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 Loans.

          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 Required 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 and 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 nor 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 either Borrower,
shall be deemed to constitute any representation or warranty by such
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 either Borrower and made its own decision to
make its Loans hereunder and enter into this Agreement.  Each Lender also
<PAGE>
 
                                                                              84

represents that it will, independently and without reliance upon either
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
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 any Loan Party.  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 any Loan Party which
may come into the possession of such Administrative Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

          10.7  Indemnification.  The Lenders agree to indemnify the
                ---------------                                     
Administrative Agents in their respective capacities as such (to the extent not
reimbursed by the Borrowers and without limiting the obligation of either
Borrower to do so), ratably according to their respective Commitment Percentages
in effect on the date on which indemnification is sought, 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 Loans) be imposed on, incurred by or asserted against the
Administrative Agents in any way relating to or arising out of, the Commitments,
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 the Administrative Agents under or in
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
resulting solely from an 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 Capacity.  The
                --------------------------------------------------      
Administrative Agents and their Affiliates may make loans to, accept deposits
from and generally engage in any kind of business with either Borrower as though
the Administrative Agents were not the Administrative Agents hereunder and under
the other Loan Documents.  With respect to the Loans made 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 the Administrative Agent, and the terms "Lender" and "Lenders" shall
include such Administrative Agent in its individual capacity.

          10.9  Successor Administrative Agent.  Each Administrative Agent may
                ------------------------------                                
resign as Administrative Agent upon 15 Business Days' prior written notice to
the Borrowers and the Lenders.  If either Administrative Agent shall resign as
Administrative Agent under this Agreement and the other Loan Documents, then the
Required Lenders shall appoint from among the Lenders a successor agent for the
Lenders, which successor agent (provided that it shall have been approved by the
Company), shall succeed to the rights, powers and duties of such Administrative
Agent hereunder.  Such resignation shall take effect upon the

                                                                              85

appointment of a successor agent.  Effective upon such appointment and approval,
the term "Administrative Agent" shall mean such successor agent, and such former
Administrative Agent's rights, powers and duties as 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 Loans.  After any retiring Administrative Agent's resignation as
Administrative Agent, the provisions of this Section 10 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.


                           SECTION 11.  MISCELLANEOUS

          11.1  Amendments and Waivers.  (a)  Neither this Agreement nor any
                ----------------------                                      
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
subsection. The Required Lenders may, or, with the written consent of the
Required Lenders, the US Administrative Agent may, from time to time, (1) enter
into with the Borrowers written amendments, supplements or modifications hereto
and to the other Loan Documents for the purpose of adding any provisions to this
Agreement or the other Loan Documents or changing in any manner the rights of
the Lenders or of the Borrowers hereunder or thereunder or (2) waive, on such
terms and conditions as the Required Lenders or the Administrative Agents, as
the case may be, may specify in such instrument, any of the requirements of this
Agreement or the other Loan Documents or any Default or Event of Default and its
consequences; provided, however, that no such waiver and no such amendment,
              --------  -------                                            
supplement or modification shall (i) reduce the amount or extend the scheduled
date of maturity of any Loan or of any installment thereof, or reduce the stated
rate of any interest or fee payable hereunder or extend the scheduled date of
any payment thereof or increase the amount or extend the expiration date of any
Lender's Commitments, in each case without the consent of each Lender affected
thereby, or (ii) amend, modify or waive any provision of this subsection or
reduce the percentage specified in the definition of Required Lenders or consent
to the assignment or transfer by either Borrower of any of its rights and
obligations under this Agreement and the other Loan Documents or release all or
substantially all of the Collateral, in each case without the written consent of
all the Lenders, or (iii) reduce the percentage specified in the definition of
Required US$ Lenders or Required C$ Lenders without the written consent of all
the US$ Lenders or C$ Lenders, respectively, or (iv) amend, modify or waive any
provision of Section 10 without the written consent of the then Administrative
Agents, or (v) amend, modify or waive any provision of this Agreement regarding
the allocation of prepayment amounts among the US$ Loans and the C$ Loans or the
application of such prepayment amounts to the respective installments of
principal under the respective US$ Loans and C$ Loans without the written
consent of the Required US$ Lenders and the Required C$ Lenders; or (vi) subject
to clause (i) of this proviso as it relates to reducing the amount or extending
the scheduled date of maturity of any Loan or any installment thereof, amend,
modify or waive any provision of (x) Section 2 without the written consent of
the Required US$ Lenders or (y) Section 3 without the written consent of the
Required C$ Lenders.  Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding
upon the Borrowers, the Lenders, the Administrative Agents and all
<PAGE>
 
                                                                              86

future holders of the Loans.  In the case of any waiver, the Borrowers, the
Lenders and the Administrative Agents shall be restored to their former
positions and rights hereunder and under the other Loan Documents, and any
Default or Event of Default waived shall be deemed to be cured and not
continuing; no such waiver shall extend to any subsequent or other Default or
Event of Default or impair any right consequent thereon.

          (b)  If in connection with any proposed amendment, supplement, waiver
or other modification of any of the provisions of this Agreement as contemplated
by subsection 11.1(a), the consent of the Required Lenders or of all of the
Lenders, as the case may be, for the relevant level of consent required, is not
obtained, the Borrowers shall have the rights as follows.  In matters requiring
the consent of all Lenders or the consent of the Required Lenders, the Borrowers
shall have the right to require any nonconsenting Lender to transfer or assign,
in whole or in part, without recourse (in accordance with subsection 11.6) all
or part of its interest, rights and obligations under this Agreement to another
Person (provided that the relevant Borrower with the reasonable cooperation of
such Lender identifies a Person which is ready, willing and able to be an
Assignee with respect to thereto which shall assume such assigned obligations
(which Assignee may be another Lender, if such Assignee Lender accepts such
assignment); provided that (A) the Assignee shall have paid to such Lender in
             --------                                                        
immediately available funds an amount equal to the principal of and interest
accrued to the date of such payment on the Loans made by it hereunder and all
other amounts owed to it hereunder, including, without limitation, any amounts
that would be owing under subsection 4.12 if such Loans were prepaid on the date
of such assignment, and (B) such assignment of the Commitment of such Lender and
prepayment of Loans does not conflict with any law, rule or regulation or order
of any Governmental Authority.  In cases where the consent referred to above is
only with respect to the Required C$ Lenders or Required US$ Lenders, the
foregoing provisions shall only apply to the Required C$ Lenders or Required US$
Lenders, as the case may be.

          (b)  Any Lender may, with the consent of the relevant Borrower and the
relevant Administrative Agent (which in each case shall not be unreasonably
withheld), in the ordinary course of its commercial banking 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 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 Loan 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.  No Lender shall be entitled to create
in favor of any Participant, in the participation agreement pursuant to which
such Participant's participating interest shall be created or otherwise, any
right to vote on, consent to or approve any matter relating to this Agreement or
any other Loan Document except for those specified in clauses (i) and (ii) of
the proviso to subsection 11.1(a).  Each Borrower agrees that if amounts
outstanding under this Agreement 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, to the maximum extent permitted by applicable law, be
deemed to have the right of setoff in respect of its participating interest in
amounts owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, 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 Company also agrees 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, with the consent of the relevant Borrower
and the relevant Administrative Agent (which in each case shall not be
unreasonably withheld), to an additional bank or financial institution (an
                                                                          
"Assignee") all or any part of its rights and obligations under this Agreement
- ---------                                                                     
and the other Loan Documents pursuant to an Assignment and Acceptance (an
                                                                         
"Assignment and Acceptance"), substantially in the form of Exhibit G, 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 and the relevant
Administrative Agent) and delivered to the relevant Administrative Agent for its
acceptance and recording in the relevant Register, provided that, in the case of
                                                   --------                     
any such assignment to an additional bank or financial institution, the sum of
the aggregate principal amount of the Loans and the aggregate amount of the
Available US

                                                                              90

Commitment or Available Canadian Commitment, as the case may be, being assigned
is equal to at least US$10,000,000 and C$10,000,000, respectively (or such
lesser amount as may be agreed to by the relevant Borrower and the relevant
Administrative Agent).  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).  Notwithstanding any
provision of this paragraph (c) and paragraph (e) of this subsection, the
consent of either Borrower 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 the relevant Borrower, for any assignment which occurs
at any time when any of the events described in subsection 9(f) shall have
occurred and be continuing.

          (d)  Each Administrative Agent, on behalf of the relevant Borrower
shall maintain at the address of such Administrative Agent referred to in
subsection 11.2 a copy of each Assignment and Acceptance delivered to it and a
register (each a "Register") for the recordation of the names and addresses of
                  --------                                                    
the Lenders and the Commitments of, and principal amounts of the Loans owing to,
each Lender from time to time.  The entries in the Register 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 the
Registers as the owner of a Loan or other obligation hereunder as the owner
thereof for all purposes of this Agreement and the other Loan Documents,
notwithstanding any notice to the contrary.  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 either 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 relevant Borrower and the relevant
Administrative Agent) together with payment by the Assignee and/or the assigning
Lender to the US Administrative Agent of a registration and processing fee of
US$3,500, the US 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 Register and give notice of such
acceptance and recordation to the Lenders and the relevant Borrower.

          (f)  Each Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee
                                  ----------                                 
approved by the Company any and all financial information in such Lender's
possession concerning such Borrower and its Subsidiaries which has been
delivered to such Lender by or on behalf of such Borrower pursuant to this
Agreement or which has been delivered to such Lender by or on behalf of

                                                                              91

such Borrower in connection with such Lender's credit evaluation of such
Borrower and its Subsidiaries prior to becoming a party to this Agreement;
                                                                          
provided that such Transferee or prospective Transferee agrees to be bound by

the provisions of subsection 11.16.

          (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") shall at any time receive any payment of all or part of its Loans which
shall have been made under either Commitment, 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 subsection
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 shall purchase for cash from the other Lenders a participating interest
in such portion of each such other Lender's Loan, or shall provide such other
Lenders with the benefits of any such collateral, or the proceeds thereof, as

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

Judgment Currency; if the amount of the Agreement Currency so purchased is less
than the sum originally due to the Applicable Creditor in the Agreement
Currency, such Loan Party agrees, as a separate obligation and notwithstanding
any such judgment, to indemnify the Applicable Creditor against such loss,

                             SECTION 2.  GUARANTEE

          2.1  Guarantee.  (a)(i)  The Company hereby, unconditionally and
               ---------                                                  
irrevocably, guarantees to the US Administrative Agent, for the benefit of the
C$ Lenders and their respective successors, indorsees, transferees and assigns,
the prompt and complete payment and performance by the Canadian Borrower when
due (whether at the stated maturity, by acceleration or otherwise) of the
Canadian Borrower Obligations, and (ii) each of the Guarantors other than the
Company hereby, jointly and severally, unconditionally and irrevocably,
guarantees to the US Administrative Agent, for the benefit of the US$ Lenders
and their respective successors, indorsees, transferees and assigns, the prompt
and complete payment and performance by the Company when due (whether at the
stated maturity, by acceleration or otherwise) of the Company Obligations.

          (b)  Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor (other than the
Company) hereunder and under the other Loan Documents shall in no event exceed
the amount which can be guaranteed by such Guarantor under applicable federal
and state laws relating to the insolvency of debtors (after giving effect to the
right of contribution established in Section 2.2).

          (c)  Each Guarantor agrees that the Company Obligations or the
Canadian Borrower Obligations, as the case may be, may at any time and from time
to time exceed the amount of the liability of such Guarantor hereunder without
impairing the guarantee contained in this Section 2 or affecting the rights and
remedies of the US Administrative Agent or any Lender hereunder.

          (d)  The guarantee contained in this Section 2 shall remain in full
force and effect until all the Company Obligations and the Canadian Borrower
Obligations, and the obligations of each Guarantor under the guarantee contained
in this Section 2 shall have been satisfied by payment in full, no Bankers'
Acceptance shall be outstanding, and the Commitments shall be terminated,
notwithstanding that from time to time during the term of the Amended and
Restated Credit Agreement either Borrower may be free from any Company
Obligations or Canadian Borrower Obligations, as the case may be.

          (e)  No payment made by either Borrower, any of the Guarantors, any
other guarantor or any other Person or received or collected by the US
Administrative Agent or any Lender from either Borrower, any of the Guarantors,
any other guarantor or any other Person by virtue of any action or proceeding or
any set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Company Obligations or the Canadian Borrower
Obligations, as the case may be, shall be deemed to modify, reduce, release or
otherwise affect the liability of any Guarantor hereunder which shall,
<PAGE>
 
notwithstanding any such payment (other than any payment made by such Guarantor
in respect of the Company Obligations or the Canadian Borrower Obligations or
any payment received or collected from such Guarantor in respect of the Company
Obligations or Canadian Borrower Obligations, as the case may be), remain liable
for the Company Obligations or the Canadian Borrower Obligations, as the case
may be, up to the maximum liability of such Guarantor hereunder until the
Company Obligations and the Canadian Borrower Obligations are paid in full, no
Bankers' Acceptance shall be outstanding, and the Commitments are terminated.

          2.2  Right of Contribution.  Each Guarantor (other than the Company)
               ---------------------                                          
hereby agrees that to the extent that a Guarantor (other than the Company) shall
have paid more than its proportionate share of any payment made hereunder, such
Guarantor shall be entitled to seek and receive contribution from and against
any other Guarantor hereunder which has not paid its proportionate share of such
payment.  Each Guarantor's right of contribution shall be subject to the terms
and conditions of Section 2.3.  The provisions of this Section 2.2 shall in no
respect limit the obligations and liabilities of any Guarantor to the US
Administrative Agent and the US$ Lenders or C$ Lenders, as the case may be, and
each Guarantor shall remain liable to the US Administrative Agent and the US$
Lenders or C$ Lenders, as the case may be, for the full amount guaranteed by
such Guarantor hereunder.

          2.3  No Subrogation.  Notwithstanding any payment made by any
               --------------                                          
Guarantor hereunder or any set-off or application of funds of any Guarantor by
the US Administrative Agent or any Lender, no Guarantor shall be entitled to be
subrogated to any of the rights of the US Administrative Agent or any US$ Lender
or C$ Lender, as the case may be, against the Company or the Canadian Borrower,
as the case may be, or any other Guarantor or any collateral security or
guarantee or right of offset held by the US Administrative Agent or any US$
Lender or C$ Lender, as the case may be, for the payment of the Company
Obligations or the Canadian Borrower Obligations, as the case may be, nor shall
any Guarantor seek or be entitled to seek any contribution or reimbursement from
the relevant Borrower or any other Guarantor in respect of payments made by such
Guarantor hereunder, until all amounts owing to the US Administrative Agent and
the US$ Lenders or the C$ Lenders, as the case may be, by the relevant Borrower
on account of the Company Obligations or the Canadian Borrower Obligations, as
the case may be, are paid in full, no Bankers' Acceptance shall be outstanding
and the Commitments are terminated.  If any amount shall be paid to any
Guarantor on account of such subrogation rights at any time when all of the
Company Obligations or the Canadian Borrower Obligations, as the case may be,
shall not have been paid in full, such amount shall be held by such Guarantor in
trust for the US Administrative Agent and the US$ Lenders or the C$ Lenders, as
the case may be, segregated from other funds of such Guarantor, and shall,
forthwith upon receipt by such Guarantor, be turned over to the US
Administrative Agent in the exact form received by such Guarantor (duly indorsed
by such Guarantor to the US Administrative Agent, if required), to be applied
against the Company Obligations, or the Canadian Borrower Obligations, as the
case may be, whether matured or unmatured, in such order as the US
Administrative Agent may determine.

          2.4  Amendments, etc. with respect to the Guarantor Obligations.  Each
               ----------------------------------------------------------       
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of
<PAGE>
 
rights against any Guarantor and without notice to or further assent by any
Guarantor, any demand for payment of any of the Company Obligations or the
Canadian Borrower Obligations, as the case may be, made by the US Administrative
Agent or any Lender may be rescinded by the US Administrative Agent or such
Lender and any of the Company Obligations or the Canadian Borrower Obligations,
as the case may be, may be continued, and the Company Obligations, the Canadian
Borrower Obligations or the liability of any other Person upon or for any part
thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the US Administrative Agent or any Lender, and the Amended and
Restated Credit Agreement and the other Loan Documents and any other documents
executed and delivered in connection therewith may be amended, modified,
supplemented or terminated, in whole or in part, as the US Administrative Agent
(or the Required Lenders, as the case may be) may deem advisable from time to
time, and any collateral security, guarantee or right of offset at any time held
by the US Administrative Agent or any Lender for the payment of the Company
Obligations or the Canadian Borrower Obligations, as the case may be, may be
sold, exchanged, waived, surrendered or released.  Neither the US Administrative
Agent nor any Lender shall have any obligation to protect, secure, perfect or
insure any Lien at any time held by it as security for the Company Obligations,
the Canadian Borrower Obligations or for the guarantee contained in this Section
2 or any property subject thereto, except as provided in Section 7.2.

          2.5  Guarantee Absolute and Unconditional.  Each Guarantor waives any
               ------------------------------------                            
and all notice of the creation, renewal, extension or accrual of any of the
Company Obligations or the Canadian Borrower Obligations, as the case may be,
and notice of or proof of reliance by the US Administrative Agent or any Lender
upon the guarantee contained in this Section 2 or acceptance of the guarantee
contained in this Section 2; the Company Obligations, the Canadian Borrower
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred, or renewed, extended, amended or waived, in reliance
upon the guarantee contained in this Section 2; and all dealings between either
Borrower and any of the Guarantors, on the one hand, and the US Administrative
Agent and the Lenders, on the other hand, likewise shall be conclusively
presumed to have been had or consummated in reliance upon the guarantee
contained in this Section 2.  Each Guarantor waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon
either Borrower or any of the Guarantors with respect to the Company Obligations
or the Canadian Borrower Obligations, as the case may be.  Each Guarantor
understands and agrees that the guarantee contained in this Section 2 shall be
construed as a continuing, absolute and unconditional guarantee of payment
without regard to (a) the validity or enforceability of the Amended and Restated
Credit Agreement or any other Loan Document, any of the Company Obligations or
the Canadian Borrower Obligations, as the case may be, or any other collateral
security therefor or guarantee or right of offset with respect thereto at any
time or from time to time held by the US Administrative Agent or any Lender, (b)
any defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by either
Borrower against the US Administrative Agent or any Lender, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of either
Borrower or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of either Borrower for the Company
Obligations or the Canadian
<PAGE>
 
Borrower Obligations, as the case may be, or of such Guarantor under the
guarantee contained in this Section 2, in bankruptcy or in any other instance.
When making any demand hereunder or otherwise pursuing its rights and remedies
hereunder against any Guarantor, the US Administrative Agent or any Lender may,
but shall be under no obligation to, make a similar demand on or otherwise
pursue such rights and remedies as it may have against either Borrower, any
other Guarantor or any other Person or against any collateral security or
guarantee for the Company Obligations or the Canadian Borrower Obligations, as
the case may be, or any right of offset with respect thereto, and any failure by
the US Administrative Agent or any Lender to make any such demand, to pursue
such other rights or remedies or to collect any payments from either Borrower,
any other Guarantor or any other Person or to realize upon any such collateral
security or guarantee or to exercise any such right of offset, or any release of
either Borrower, any other Guarantor or any other Person or any such collateral
security, guarantee or right of offset, shall not relieve any Guarantor of any
obligation or liability hereunder, and shall not impair or affect the rights and
remedies, whether express, implied or available as a matter of law, of the US
Administrative Agent or any Lender against any Guarantor.  For the purposes
hereof "demand" shall include the commencement and continuance of any legal
proceedings.

          2.6  Reinstatement.  The guarantee contained in this Section 2 shall
               -------------                                                  
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Company Obligations or the Canadian
Borrower Obligations is rescinded or must otherwise be restored or returned by
the US Administrative Agent or any Lender upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of either Borrower or any Guarantor,
or upon or as a result of the appointment of a receiver, intervenor or
conservator of, or trustee or similar officer for, either Borrower or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made.

          2.7  Payments.  Each Guarantor hereby guarantees that payments
               --------

benefit of the Lenders, a security interest in, all of the following property

     of any and all of the foregoing and all collateral security and guarantees
     given by any Person with respect to any of the foregoing (except to the
     extent the creation of such Lien would cause a breach or termination of
     such collateral security or guarantees under the terms thereof and of any
     applicable law).

included in the deposit.

          (c)  At the US Administrative Agent's request, each Guarantor shall
make available to the US Administrative Agent all original and other documents
evidencing, and relating to, the agreements and transactions which gave rise to
the Receivables, including, without limitation, all original invoices.

          6.2  Communications with Obligors; Guarantors Remain Liable.   (a)

          (b)  Upon the request of the US Administrative Agent at any time
during the continuance of an Event of Default, each Guarantor shall notify

obligation or liability under any agreement relating to a Receivable by reason
of or arising out of this Agreement or the receipt by the US Administrative
Agent or any Lender of any payment relating thereto, nor shall the US
Administrative Agent or any Lender be obligated in any manner to perform any of
the obligations of any Guarantor under or pursuant to any Receivable (or any
agreement giving rise thereto), to make any payment, to make any inquiry as to
the nature or the sufficiency of any payment received by it or as to the
sufficiency of any performance by any party thereunder, to present or file any
claim, to take any action to enforce any performance or to collect the payment
of any amounts which may have been assigned to it or to which it may be entitled
at any time or times.

respect of the Pledged Stock and all payments made in respect of the Pledged
Notes, and to exercise all voting and corporate or partnership rights with
respect to the Pledged Securities; provided, however, that no vote shall be cast
                                   --------  -------                            
or corporate or partnership right exercised or other action taken which, in the
US Administrative Agent's

reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of the Amended and Restated
Credit Agreement, this Agreement or any other Loan Document.

          (b)  If an Event of Default shall occur and be continuing and the US
Administrative Agent shall give notice of its intent to exercise such rights to
the relevant Guarantor or Guarantors, (i) the US Administrative Agent shall have
the right to receive any and all cash dividends, payments or other Proceeds paid

Obligations in such order as the US Administrative Agent may determine, and (ii)
any or all of the Pledged Securities shall be registered in the name of the US
Administrative Agent or its nominee, and the US Administrative Agent or its
nominee may thereafter exercise (x) all voting, corporate and other rights
pertaining to such Pledged Securities at any meeting of shareholders of the
relevant Issuer or Issuers or otherwise and (y) any and all rights of
conversion, exchange, subscription and any other rights, privileges or options
pertaining to such Pledged Securities as if it were the absolute owner thereof
(including, without limitation, the right to exchange at its discretion any and
all of the Pledged Securities upon the merger, consolidation, reorganization,
recapitalization or other fundamental change in the corporate structure of any
Issuer, or upon the exercise by any Guarantor or the US Administrative Agent of
any right, privilege or option pertaining to such Pledged Securities, and in
connection therewith, the right to deposit and deliver any and all of the
Pledged Securities with any committee, depositary, transfer agent, registrar or
other designated agency upon such terms and conditions as the US Administrative
Agent may determine), all without liability except to account for property
actually received by it, but the US Administrative Agent shall have no duty to
any Guarantor to exercise any such right, privilege or option and shall not be
responsible for any failure to do so or delay in so doing.

          (c)  Each Guarantor hereby authorizes and instructs each Issuer of any
Pledged Securities pledged by such Guarantor hereunder to (i) comply with any
instruction received by it from the US Administrative Agent in writing that (x)
states that an Event of Default has occurred and is continuing and (y) is
otherwise in accordance with the terms of this Agreement, without any other or
further instructions from such Guarantor, and each Guarantor agrees that each
Issuer shall be fully protected in so complying, and (ii) unless otherwise
expressly permitted hereby, pay any dividends or other payments with respect to
the Pledged Securities directly to the US Administrative Agent.

          6.4  Proceeds to be Turned Over To US Administrative Agent.  In
               -----------------------------------------------------     
addition to the rights of the US Administrative Agent and the Lenders specified
in Section 6.1 with respect to payments of Receivables, if an Event of Default
shall occur and be continuing, all Proceeds received by any Guarantor consisting
of cash, checks and other near-cash items shall be held by such Guarantor in
trust for the US Administrative Agent and the Lenders, segregated from other
funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be
turned over to the US Administrative Agent in the exact form received by such
Guarantor (duly indorsed by such Guarantor to the US Administrative Agent, if
required).  All Proceeds received by the US Administrative Agent hereunder shall
be held by the US Administrative Agent in a Collateral Account maintained under
its sole dominion and control.  All Proceeds while held by the US Administrative
Agent in a Collateral Account (or by such
<PAGE>
 
Guarantor in trust for the US Administrative Agent and the Lenders) shall
continue to be held as collateral security for all the Obligations and shall not
constitute payment thereof until applied as provided in Section 6.5.

          6.5  Application of Proceeds.  At such intervals as may be agreed upon
               -----------------------                                          
by the Borrowers and the US Administrative Agent, or, if an Event of Default
shall have occurred and be continuing, at any time at the US Administrative
Agent's election, the US Administrative Agent may apply all or any part of
Proceeds held in any Collateral Account in payment of the Obligations in such
order as the US Administrative Agent may elect (provided that all such payments
in respect of principal, interest, fees and other amounts then due and payable
hereunder shall in each case be applied pro rata among those Lenders to which
                                        --------                             
such types of amounts are payable), and any part of such funds which the US
Administrative Agent elects not so to apply and deems not required as collateral
security for the Obligations shall be paid over from time to time by the US
Administrative Agent to the Borrowers or to whomsoever may be lawfully entitled
to receive the same.  Any balance of such Proceeds remaining after the
Obligations shall have been paid in full, no Bankers' Acceptances shall be
outstanding and the Commitments shall have terminated shall be paid over to the
Borrowers or to whomsoever may be lawfully entitled to receive the same.

          6.6  Code and Other Remedies.  If an Event of Default shall occur and
               -----------------------                                         
be continuing, the US Administrative Agent, on behalf of the Lenders, may
exercise, in addition to all other rights and remedies granted to them in this
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, all rights and remedies of a secured party under
the Code or any other applicable law.  Without limiting the generality of the
foregoing, the US Administrative Agent, without demand of performance or other
demand, presentment, protest, advertisement or notice of any kind (except any
notice required by law referred to below) to or upon any Guarantor or any other
Person (all and each of which demands, defenses, advertisements and notices are
hereby waived), may in such circumstances forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, lease, assign, give option or options to purchase, or otherwise
dispose of and deliver the Collateral or any part thereof (or contract to do any
of the foregoing), in one or more parcels at public or private sale or sales, at
any exchange, broker's board or office of the US Administrative Agent or any
Lender or elsewhere upon such terms and conditions as it may deem commercially
reasonable and at such prices as it may deem best for cash or on credit or for
future delivery without assumption of any credit risk.  The US Administrative
Agent or any Lender shall have the right upon any such public sale or sales,
and, to the extent permitted by law, upon any such private sale or sales, to
purchase the whole or any part of the Collateral so sold, free of any right or
equity of redemption in any Guarantor, which right or equity is hereby waived or
released.  Each Guarantor further agrees, at the US Administrative Agent's
request, to assemble the Collateral and make it available to the US
Administrative Agent at places which the US Administrative Agent shall
reasonably select, whether at such Guarantor's premises or elsewhere.  The US
Administrative Agent shall apply the net proceeds of any action taken by it
pursuant to this Section 6.6, after deducting all reasonable costs and expenses
of every kind incurred in connection therewith or incidental to the care or
safekeeping of any of the Collateral or in any way relating to the Collateral or
the rights of the US Administrative Agent and the Lenders
<PAGE>
 
hereunder, including, without limitation, reasonable attorneys' fees and
disbursements, to the payment in whole or in part of the Obligations, in such
order as the US Administrative Agent may elect (provided that such application
                                                --------                      
shall in each case be applied pro rata among those Lenders to which such types
                              --------                                        
of amounts are payable), and only after such application and after the payment
by the US Administrative Agent of any other amount required by any provision of
law, including, without limitation, Section 9-504(1)(c) of the Code, need the US
Administrative Agent account for the surplus, if any, to any Guarantor.  To the
extent permitted by applicable law, each Guarantor waives all claims, damages
and demands it may acquire against the US Administrative Agent or any Lender
arising out of the exercise by them of any rights hereunder.  If any notice of a
proposed sale or other disposition of Collateral shall be required by law, such
notice shall be deemed reasonable and proper if given at least 10 days before
such sale or other disposition.

          6.7  Registration Rights.  (a)  If the US Administrative Agent shall
               -------------------                                            
determine to exercise its right to sell any or all of the Pledged Stock pursuant
to Section 6.6, and if in the opinion of the US Administrative Agent it is
necessary or advisable to have the Pledged Stock, or that portion thereof to be
sold, registered under the provisions of the Securities Act, upon written
request, the relevant Guarantor will use its best efforts to cause the Issuer
thereof to (i) execute and deliver, and cause the directors and officers of such
Issuer to execute and deliver, all such instruments and documents, and do or
cause to be done all such other acts as may be, in the opinion of the US
Administrative Agent, necessary or advisable to register the Pledged Stock, or
that portion thereof to be sold, under the provisions of the Securities Act,
(ii) use its best efforts to cause the registration statement relating thereto
to become effective and to remain effective for a period of one year from the
date of the first public offering of the Pledged Stock, or that portion thereof
to be sold, and (iii) make all amendments thereto and/or to the related
prospectus which, in the opinion of the US Administrative Agent, are necessary
or advisable, all in conformity with the requirements of the Securities Act and
the rules and regulations of the Securities and Exchange Commission applicable
thereto; provided, that the Guarantor shall not be required to effect such
         --------                                                         
registration under the Securities Act or with applicable state securities laws
if the Guarantor delivers to the US Administrative Agent an opinion of counsel
(who shall be satisfactory to the US Administrative Agent) satisfactory to the
US Administrative Agent that such sale may be made pursuant to an exemption from
the Securities Act and such state securities laws, and provided further, that
                                                       ----------------      
the US Administrative Agent shall furnish to such Guarantor such information
regarding the US Administrative Agent and the Lenders as such Guarantor may
request in writing and as shall be required in connection with any such
registration, qualification or compliance.  Each Guarantor agrees to use its
best efforts to cause such Issuer to comply with the provisions of the
securities or "Blue Sky" laws of any and all jurisdictions which the US
Administrative Agent shall designate and, except where the US Administrative
Agent does not deem it necessary or desirable to do so under the Securities Act
and the rules and regulations of the Securities and Exchange Commission
applicable thereto, to make available to its security holders, as soon as
practicable, an earnings statement (which need not be audited) which will
satisfy the provisions of Section 11(a) of the Securities Act.

          (b)  Each Guarantor recognizes that the US Administrative Agent may be
unable to effect a public sale of any or all the Pledged Stock, by reason of
certain
<PAGE>
 
prohibitions contained in the Securities Act and applicable state securities
laws or otherwise, and may be compelled to resort to one or more private sales
thereof to a restricted group of purchasers which will be obliged to agree,
among other things, to acquire such securities for their own account for
investment and not with a view to the distribution or resale thereof.  Each
Guarantor acknowledges and agrees that the mere fact that any such private sale
may result in prices and other terms less favorable than if such sale were a
public sale and agrees that the mere fact that such sale is a private sale shall
not be deemed to have made such sale one not made in a commercially reasonable
manner, provided that such Pledged Stock is sold at a price that the US
        --------                                                       
Administrative Agent has determined in good faith is reasonable under the
circumstances.  The US Administrative Agent shall be under no obligation to
delay a sale of any of the Pledged Stock for the period of time necessary to
permit the Issuer thereof to register such securities for public sale under the
Securities Act, or under applicable state securities laws, even if such Issuer
would agree to do so.

          (c)  Each Guarantor agrees to use its best efforts to do or cause to
be done all such other acts as may be necessary to make such sale or sales of
all or any portion of the Pledged Stock pledged by it pursuant to this Section
6.7 valid and binding and in compliance with any and all other applicable
Requirements of Law.  Each Guarantor further agrees that a breach of any of the
covenants contained in this Section 6.7 will cause irreparable injury to the US
Administrative Agent and the Lenders, that the US Administrative Agent and the
Lenders have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this Section 6.7 shall be
specifically enforceable against such Guarantor, and such Guarantor hereby
waives and agrees not to assert any defenses against an action for specific
performance of such covenants except for a defense that no Event of Default has
occurred and is continuing under the Amended and Restated Credit Agreement.

          6.8  Waiver; Deficiency.  Each Guarantor waives and agrees not to
               ------------------                                          
assert any rights or privileges which it may acquire under Section 9-112 of the
Code.  Each Guarantor shall remain liable for any deficiency if the proceeds of
any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the US
Administrative Agent or any Lender to collect such deficiency.


                    SECTION 7.  THE US ADMINISTRATIVE AGENT

          7.1  US Administrative Agent's Appointment as Attorney-in-Fact, etc.
               --------------------------------------------------------------  
(a)  Each Guarantor hereby irrevocably constitutes and appoints the US
Administrative Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Guarantor and in the name of
such Guarantor or in its own name, for the purpose of carrying out the terms of
this Agreement, to take any and all appropriate action and to execute any and
all documents and instruments which may be reasonably necessary or desirable to
accomplish the purposes of this Agreement, and, without limiting the generality
of the foregoing, each Guarantor hereby gives the US Administrative Agent the
power and right, on behalf of such Guarantor, without notice to or assent by
such Guarantor, to do any or all of the following:
<PAGE>
 
          (i)  in the name of such Guarantor or its own name, or otherwise, take
     possession of and indorse and collect any checks, drafts, notes,
     acceptances or other instruments for the payment of moneys due under any
     Receivable or with respect to any other Collateral and file any claim or
     take any other action or proceeding in any court of law or equity or
     otherwise deemed appropriate by the US Administrative Agent for the purpose
     of collecting any and all such moneys due under any Receivable or with
     respect to any other Collateral whenever payable;

          (ii)  in the case of any Copyright, Patent or Trademark, execute and
     deliver any and all agreements, instruments, documents and papers as the US
     Administrative Agent may request to evidence the US Administrative Agent's
     and the Lenders' security interest in such Copyright, Patent or Trademark
     and the goodwill and general intangibles of such Guarantor relating thereto
     or represented thereby;

          (iii)  pay or discharge taxes and Liens levied or placed on or
     threatened against the Collateral, effect any repairs or any insurance
     called for by the terms of this Agreement and pay all or any part of the
     premiums therefor and the costs thereof;

          (iv)  execute, in connection with any sale provided for in Section 6.6
     or 6.7, any indorsements, assignments or other instruments of conveyance or
     transfer with respect to the Collateral; and

          (v)  (1) direct any party liable for any payment under any of the
     Collateral to make payment of any and all moneys due or to become due
     thereunder directly to the US Administrative Agent or as the US
     Administrative Agent shall direct; (2) ask or demand for, collect, receive
     payment of and receipt for, any and all moneys, claims and other amounts
     due or to become due at any time in respect of or arising out of any
     Collateral; (3) sign and indorse any invoices, freight or express bills,
     bills of lading, storage or warehouse receipts, drafts against debtors,
     assignments, verifications, notices and other documents in connection with
     any of the Collateral; (4) commence and prosecute any suits, actions or
     proceedings at law or in equity in any court of competent jurisdiction to
     collect the Collateral or any portion thereof and to enforce any other
     right in respect of any Collateral; (5) defend any suit, action or
     proceeding brought against such Guarantor with respect to any Collateral;
     (6) settle, compromise or adjust any such suit, action or proceeding and,
     in connection therewith, to give such discharges or releases as the US
     Administrative Agent may deem appropriate; (7) assign any Copyright, Patent
     or Trademark (along with the goodwill of the business to which any such
     Copyright, Patent or Trademark pertains), throughout the world for such
     term or terms, on such conditions, and in such manner, as the US
     Administrative Agent shall in its sole discretion determine; and (8)
     generally, sell, transfer, pledge and make any agreement with respect to or
     otherwise deal with any of the Collateral as fully and completely as though
     the US Administrative Agent were the absolute owner thereof for all
     purposes, and do, at the US Administrative Agent's option and such
     Guarantor's expense, at any time, or from time to time, all acts and things
     which the US Administrative Agent deems necessary to protect, preserve or
     realize upon the Collateral and the US Administrative Agent's and the
     Lenders' security interests
<PAGE>
 
     therein and to effect the intent of this Agreement, all as fully and
     effectively as such Guarantor might do.

          Anything in this Section 7.1(a) to the contrary notwithstanding, the
US Administrative Agent agrees that it will not exercise any rights under the
power of attorney provided for in this Section 7.1(a) unless an Event of Default
shall have occurred and be continuing.

          (b)  If any Guarantor fails to perform or comply with any of its
agreements contained herein, the US Administrative Agent, at its option, but
without any obligation so to do, may perform or comply, or otherwise cause
performance or compliance, with such agreement.

          (c)  The expenses of the US Administrative Agent incurred in
connection with actions undertaken as provided in this Section 7.1, together
with interest thereon at a rate per annum equal to the rate per annum at which
interest would then be payable on past due Base Rate Loans, in the case of
expenses paid in US$, or C$ Prime Loans, in the case of expenses paid in C$
under the Amended and Restated Credit Agreement, from the date of payment by the
US Administrative Agent to the date reimbursed by the relevant Guarantor, shall
be payable by such Guarantor to the US Administrative Agent on demand.

          (d)  Each Guarantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof.  All powers, authorizations
and agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

          7.2  Duty of Administrative Agent.  The US Administrative Agent's sole
               ----------------------------                                     
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the Code or otherwise,
shall be to deal with it in the same manner as the US Administrative Agent deals
with similar property for its own account.  Neither the US Administrative Agent,
any Lender nor any of their respective officers, directors, employees or agents
shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of any Guarantor or any
other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof.  The powers conferred on the US Administrative
Agent and the Lenders hereunder are solely to protect the US Administrative
Agent's and the Lenders' interests in the Collateral and shall not impose any
duty upon the US Administrative Agent or any Lender to exercise any such powers.
The US Administrative Agent and the Lenders shall be accountable only for
amounts that they actually receive as a result of the exercise of such powers,
and neither they nor any of their officers, directors, employees or agents shall
be responsible to any Guarantor for any act or failure to act hereunder, except
for their own gross negligence or willful misconduct.

          7.3  Execution of Financing Statements.  Pursuant to Section 9-402 of
               ---------------------------------                               
the Code and any other applicable law, each Guarantor authorizes the US
Administrative Agent to file or record financing statements and other filing or
recording documents or instruments with
<PAGE>
 
respect to the Collateral without the signature of such Guarantor in such form
and in such offices as the US Administrative Agent reasonably determines
appropriate to perfect the security interests of the US Administrative Agent
under this Agreement.  A photographic or other reproduction of this Agreement
shall be sufficient as a financing statement or other filing or recording
document or instrument for filing or recording in any jurisdiction.

          7.4  Authority of Administrative Agent.  Each Guarantor acknowledges
               ---------------------------------                              
that the rights and responsibilities of the US Administrative Agent under this
Agreement with respect to any action taken by the US Administrative Agent or the
exercise or non-exercise by the US Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as between the US
Administrative Agent and the Lenders, be governed by the Amended and Restated
Credit Agreement and by such other agreements with respect thereto as may exist
from time to time among them, but, as between the US Administrative Agent and
the Guarantors, the US Administrative Agent shall be conclusively presumed to be
acting as agent for the Lenders with full and valid authority so to act or
refrain from acting as provided herein, and no Guarantor shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.


                           SECTION 8.  MISCELLANEOUS

          8.1  Amendments in Writing.  None of the terms or provisions of this
               ---------------------                                          
Agreement may be waived, amended, supplemented or otherwise modified except by a
written instrument executed by each affected Guarantor and the US Administrative
Agent, provided that any provision of this Agreement imposing obligations on any
       --------                                                                 
Guarantor may be waived by the US Administrative Agent in a written instrument
executed by the US Administrative Agent.

          8.2  Notices.  All notices, requests and demands to or upon the US
               -------                                                      
Administrative Agent or any Guarantor hereunder shall be effected in the manner
provided for in subsection 11.2 of the Amended and Restated Credit Agreement;
                                                                             
provided that any such notice, request or demand to or upon any Guarantor shall
- --------                                                                       
be addressed to such Guarantor at its notice address set forth on Schedule 1 as
                                                                  ----------   
such Schedule may be revised from time to time.

          8.3  No Waiver by Course of Conduct; Cumulative Remedies.  Neither the
               ---------------------------------------------------              
US Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default.  No failure to exercise, nor any delay in
exercising, on the part of the US Administrative Agent or any Lender, any right,
power or privilege hereunder shall operate as a waiver thereof.  No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.  A waiver by the US Administrative Agent or any Lender of any right
or remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the US Administrative Agent or such Lender would otherwise
have on any future occasion.  The rights and remedies
<PAGE>
 
herein provided are cumulative, may be exercised singly or concurrently and are
not exclusive of any other rights or remedies provided by law.

          8.4  Enforcement Expenses; Indemnification.  (a)  Each Guarantor
               -------------------------------------                      
agrees to pay or reimburse each Lender and the US Administrative Agent for all
its costs and expenses incurred in collecting against such Guarantor under the
guarantee contained in Section 2 or otherwise enforcing or preserving any rights
under this Agreement and the other Loan Documents to which such Guarantor is a
party, including, without limitation, the fees and disbursements of counsel to
each Lender and of counsel to the US Administrative Agent.

          (b)  Each Guarantor agrees to pay, and to save the US Administrative
Agent and the Lenders harmless from, any and all liabilities with respect to, or
resulting from any delay (except for any delay caused by the US Administrative
Agent or any Lender) in paying, any and all stamp, excise, sales or other taxes
which may be payable or determined to be payable with respect to any of the
Collateral or in connection with any of the transactions contemplated by this
Agreement.

          (c)  Each Guarantor agrees to pay, and to save the US Administrative
Agent and the Lenders harmless from, any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever with respect to the execution,
delivery, enforcement and performance of this Agreement (collectively, the
                                                                          
"indemnified liabilities") to the extent the Company would be required to do so
- ------------------------                                                       
pursuant to subsection 11.5 of the Amended and Restated Credit Agreement.

          (d)  The agreements in this Section 8.4 shall survive repayment of the
Obligations and all other amounts payable under the Amended and Restated Credit
Agreement and the other Loan Documents.

          8.5  Successors and Assigns.  This Agreement shall be binding upon the
               ----------------------                                           
successors and assigns of each Guarantor and shall inure to the benefit of the
US Administrative Agent and the Lenders and their successors and assigns;
                                                                         
provided that no Guarantor may assign, transfer or delegate any of its rights or
- --------                                                                        
obligations under this Agreement without the prior written consent of the US
Administrative Agent.

          8.6  Set-Off.  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 such Borrower to the
extent permitted by applicable law, upon any amount becoming due and payable by
such Borrower hereunder (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

executed by, each of the parties hereto pursuant to which such junior Lien is

priority, perfected security interest, (ii) the security interest created by
Section 2(b) of this Agreement as a second priority, perfected security interest
and (iii) the security interest created by Section 2(c) of this Agreement as a
third priority, perfected security interest and, in each case of clauses (i),

of all Persons whomsoever.

     (d) At any time and from time to time, upon the written request of the
Collateral Agent, and at the sole expense of such Pledgor, such Pledgor will
promptly and duly execute and deliver such further instruments and documents and

         -----------------------------                                        
occurred and be continuing and the Collateral Agent shall have given notice to
the Pledgors of the Collateral Agent's intent to exercise its corresponding
rights pursuant to Section 9 below, each Pledgor shall be permitted to receive
all cash dividends or other distributions paid in the normal course of business
of the Issuer, to the extent permitted in the Credit Agreement, in respect of
the Pledged Stock and to exercise all voting and corporate rights with respect
to the Pledged Stock; provided, however, that no vote shall be cast or corporate
                      --------  -------                                         
right exercised or other action taken which, in the Collateral Agent's
reasonable judgment, would impair the Pledged Stock or which would be
inconsistent with or result in any violation of any provision of the Credit
Agreement, any other Loan Document, any Notes, the Indentures or this Agreement.

     8.  Rights of the Secured Parties and the Collateral Agent.  (a)  All money
         ------------------------------------------------------                 
Proceeds received by the Collateral Agent hereunder shall be held by the
Collateral Agent for the benefit of the Secured Parties in a Collateral Account.
All Proceeds while held by the Collateral Agent in a Collateral Account (or by
each Pledgor in trust for the Collateral Agent
<PAGE>
 
and the Secured Parties) shall continue to be held as collateral security for
all the Secured Obligations and shall not constitute payment thereof until
applied as provided in Section 10(c).

     (b)  If an Event of Default shall occur and be continuing and the
Collateral Agent shall give notice of its intent to exercise any of such rights
to each Pledgor (1) the Collateral Agent shall have the right to receive any and
all cash dividends paid in respect of the Pledged Stock and make application
thereof to the Secured Obligations in the order provided in Section 10(c), and
(2) all shares of the Pledged Stock shall be registered in the name of the
Collateral Agent or its nominee, and the Collateral Agent or its nominee may
thereafter exercise (A) all voting, corporate and other rights pertaining to
such shares of the Pledged Stock at any meeting of shareholders of the Issuer or
otherwise and (B) any and all rights of conversion, exchange, subscription and
any other rights, privileges or options pertaining to such shares of the Pledged
Stock as if it were the absolute owner thereof (including, without limitation,
the right to exchange at its discretion any and all of the Pledged Stock upon
the merger, consolidation, reorganization, recapitalization or other fundamental
change in the corporate structure of the Issuer, or upon the exercise by either
Pledgor or the Collateral Agent of any right, privilege or option pertaining to
such shares of the Pledged Stock, and in connection therewith, the right to
deposit and deliver any and all of the Pledged Stock with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
and conditions as the Collateral Agent may determine), all without liability
except to account for property actually received by it, but the Collateral Agent
shall have no duty to any pledgee to exercise any such right, privilege or
option and shall not be responsible for any failure to do so or delay in so
doing.

     9.  Remedies.  (a)  If an Event of Default shall have occurred and be
         --------                                                         
continuing, at any time at the Collateral Agent's election, the Collateral Agent
may apply all or any part of Proceeds held in any Collateral Account in payment
of the Secured Obligations in such order as provided in Section 10(c).

     (b)  If an Event of Default shall have occurred and be continuing, the
Collateral Agent, on behalf of the Secured Parties, may exercise, in addition to
all other rights and remedies granted in this Agreement and in any other
instrument or agreement securing, evidencing or relating to the Secured
Obligations, all rights and remedies of a secured party with respect to the
Collateral under the Code.  Without limiting the generality of the foregoing,
the Collateral Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon either Pledgor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
assign, give option or options to purchase or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do any of the foregoing), in
one or more parcels at public or private sale or sales, in the over-the-counter
market, at any
<PAGE>
 
exchange, broker's board or office of the Collateral Agent or any Lender or
Holder or elsewhere upon such terms and conditions as it may deem advisable and
at such prices as it may deem best, for cash or on credit or for future delivery
without assumption of any credit risk.  The Collateral Agent or any other
Secured Party shall have the right upon any such public sale or sales, and, to
the extent permitted by law, upon any such private sale or sales, to purchase
the whole or any part of the Collateral so sold, free of any right or equity of
redemption in either Pledgor, which right or equity is hereby waived or
released.  The Collateral Agent shall apply any Proceeds from time to time held
by it and the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale, after deducting all reasonable costs and
expenses of every kind incurred in respect thereof or incidental to the care or
safekeeping of any of the Collateral or in any way relating to the Collateral or
the rights of the Collateral Agent and the Secured Parties hereunder, including,
without limitation, reasonable attorneys' fees and disbursements of counsel to
the Collateral Agent, to the payment in whole or in part of the Secured
Obligations, in the order provided in Section 10(c), and only after such
application and after the payment by the Collateral Agent of any other amount
required by any provision of law, including, without limitation, Section 9-
504(1)(c) of the Code, need the Collateral Agent account for the surplus, if
any, to the Pledgors.  To the extent permitted by applicable law, each Pledgor
waives all claims, damages and demands it may acquire against the Collateral
Agent or any other Secured Party arising out of the exercise by them of any
rights hereunder.  If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition.

     10.  Rights in Collateral; Application of Payments and Proceeds.  (a)
          ----------------------------------------------------------       
Notwithstanding anything to the contrary contained in any agreement, document or
instrument in favor of the Senior Subordinated Secured Parties and/or the Junior
Subordinated Secured Parties and irrespective of:

          (1)  the time, order or method of attachment or perfection of the
     security interests created hereby,

          (2)  the time or order of filing or recording of financing statements
     or other documents filed or recorded to perfect security interests in any
     Collateral,

          (3)  anything contained in any filing or agreement to which the Senior
     Secured Parties, the Senior Subordinated Secured Parties and/or the Junior
     Subordinated Secured Parties now or hereafter may be a party, and

          (4)  the rules for determining priority under the Code or any other
     law governing the relative priorities of secured creditors,

any security interest in the Collateral in favor of the Senior Secured Parties
has and shall have priority, to the extent of any unpaid Senior Secured
Obligations, over any security interest in
<PAGE>
 
such Collateral in favor of the Senior Subordinated Secured Parties and the
Junior Subordinated Secured Parties, and any security interest in the Collateral
in favor of the Senior Subordinated Secured Parties has and shall have priority,
to the extent of any unpaid Senior Subordinated Secured Obligations, over any
security interest in such Collateral in favor of the Junior Subordinated Secured
Parties.

     (b)  In exercising rights and remedies with respect to the Collateral, the
Collateral Agent may enforce the provisions hereof and exercise remedies
hereunder, all in such order and in such manner as the Senior Secured Parties
may determine in the exercise of their sole business judgment.  Such exercise
and enforcement shall include, without limitation, the rights to collect, sell,
dispose of or otherwise realize upon all or any part of the Collateral, to incur
expenses in connection with such collection, sale, disposition or other
realization and to exercise all the rights and remedies of a secured lender
under the Code of any applicable jurisdiction.  The Subordinated Secured Parties
hereby (1) waive any right that they may have (whether by contract, by law or
otherwise) to require the Collateral Agent to give notice of any collection,
sale, disposition or other realization of or upon any or all of the Collateral
contemplated by this Agreement or any such right the Subordinated Secured
Parties may have to object to or otherwise contest any such collection, sale,
disposition or other realization of or upon any or all of the Collateral by the
Senior Secured Parties (including, without limitation, any requirement that the
Collateral Agent foreclose upon such Collateral under applicable law) and (2)
agree not to contest or otherwise challenge any such collection, sale,
disposition or other realization of or upon all or any of the Collateral or to
assert any claim or defense that any such collection, sale, disposition or other
realization of or upon all or any part of the Collateral was not commercially
reasonable or otherwise failed to comply in any respect with applicable law.  It
is understood and agreed that, for purposes of this paragraph, after the Senior
Payout Date, the term "Senior Secured Parties", when used in this paragraph,
shall be deemed to mean the Senior Subordinated Secured Parties and the term
"Subordinated Secured Parties", when used in this paragraph, shall be deemed to
mean the Junior Subordinated Secured Parties.

     (c)  Any money, property or securities realized upon the sale, disposition
or other realization by the Collateral Agent or the Subordinated Secured
Parties, as the case may be, upon all or any part of the Collateral (including,
without limitation, any payment or distribution of assets of either Pledgor
consisting of, or in respect of, Collateral, whether in cash, property or
securities during the continuance of an Insolvency Event with respect to such
Pledgor) (collectively, "Realizations"), shall be applied in the following
                         ------------                                     
order:

          (1)  First, to the payment in full of all reasonable costs and
               -----                                                    
     expenses (including, without limitation, attorneys' reasonable fees and
     disbursements) paid or incurred by the Collateral Agent in connection with
     such Realization or the protection of its rights and interests in the
     Collateral;
<PAGE>
 
          (2)  Second, to the Administrative Agent to be applied to the payment
               ------                                                          
     in full of all Senior Secured Obligations then due and payable in such
     order as the Administrative Agent may elect in its sole discretion;

          (3)  Third, to the 1996 Trustee to be applied to the payment in full
               -----                                                          
     of all Senior Subordinated Secured Obligations then due and payable in such
     order as the 1996 Trustee may elect in its sole discretion;

          (4)  Fourth, to the 1997 Trustee to be applied to the payment in full
               ------                                                          
     of all Junior Subordinated Secured Obligations then due and payable in such
     order as the 1997 Trustee may elect in its sole discretion; and

          (5)  Fifth, to pay to the applicable Pledgor, or its representative or
               -----                                                            
     as a court of competent jurisdiction may direct, any surplus then
     remaining.

     (d)  Prior to the Senior Payout Date, the Subordinated Secured Parties
shall not (1) enforce or apply any security interest in all or any of the
Collateral, (2) collect or receive any proceeds of any of the Collateral or
otherwise enforce or apply any security interest in the proceeds of any of the
Collateral; or (3) in any other manner interfere with the security interest
granted in favor of the Senior Secured Parties in any of the Collateral (or the
proceeds thereof).  In addition, the Subordinated Secured Parties hereby (x)
agree not to assert prior to the Senior Payout Date any claim for marshalling;
(y) consent to the collection, sale, disposition or other realization of or upon
all or any of the Collateral by the Collateral Agent prior to the Senior Payout
Date free of any security interest therein in favor of the Subordinated Secured
Parties; and (z) at the sole cost and expense of the Pledgors, agree to execute
prior to the Senior Payout Date all such releases and other documents that the
Administrative Agent may reasonably request in writing to facilitate the
collection, sale, disposition or other realization of or upon any or all of the
Collateral by the Collateral Agent (including, without limitation, the
termination of any security interests in any of the Collateral in favor of the
Subordinated Secured Parties concurrently with such sale, disposition or other
realization).

     (e)  If any payment or distribution, whether consisting of money, property
or securities, from any Realizations is collected or received by the
Subordinated Secured Parties in respect of the Subordinated Secured Obligations
in violation of Section 10(d), the Subordinated Secured Parties shall forthwith
deliver the same to the Collateral Agent, in the form received, duly indorsed to
the Collateral Agent, if required, to be applied to the payment or prepayment of
the Senior Secured Obligations until the Senior Secured Obligations are paid in
full.  Until so delivered, such payment or distribution shall be held in trust
by the Subordinated Secured Parties as the property of the Senior Secured
Parties, segregated from other funds and property held by the Subordinated
Secured Parties.
<PAGE>
 
     (f)  Prior to the Senior Subordinated Payout Date, the Junior Subordinated
Secured Parties shall not (1) enforce or apply any security interest in all or
any of the Collateral, (2) collect or receive any proceeds of any of the
Collateral or otherwise enforce or apply any security interest in the proceeds
of any of the Collateral; or (3) in any other manner interfere with the security
interest granted in favor of the Senior Subordinated Secured Parties in any of
the Collateral (or the proceeds thereof).  In addition, the Junior Subordinated
Secured Parties hereby (x) agree not to assert prior to the Senior Subordinated
Payout Date any claim for marshalling; (y) consent to the collection, sale,
disposition or other realization of or upon all or any of the Collateral by the
Collateral Agent prior to the Senior Subordinated Payout Date free of any
security interest therein in favor of the Senior Subordinated Secured Parties;
and (z) at the sole cost and expense of the Pledgors, agree to execute after the
Senior Payout Date but prior to the Senior Subordinated Payout Date all such
releases and other documents that the 1996 Trustee may reasonably request in
writing to facilitate the collection, sale, disposition or other realization of
or upon any or all of the Collateral by the Collateral Agent (including, without
limitation, the termination of any security interests in any of the Collateral
in favor of the Junior Subordinated Secured Parties concurrently with such sale,
disposition or other realization).

     (g)  If any payment or distribution, whether consisting of money, property
or securities, from any Realizations is collected or received by the Junior
Subordinated Secured Parties after the Senior Payout Date in respect of the
Junior Subordinated Secured Obligations in violation of Section 10(f), the
Junior Subordinated Secured Parties shall forthwith deliver the same to the
Collateral Agent, in the form received, duly indorsed to the Collateral Agent,
if required, to be applied to the payment or prepayment of the Senior
Subordinated Secured Obligations until the Senior Subordinated Secured
Obligations are paid in full.  Until so delivered, such payment or distribution
shall be held in trust by the Junior Subordinated Secured Parties as the
property of the Senior Subordinated Secured Parties, segregated from other funds
and property held by the Junior Subordinated Secured Parties.

     11.  Release of Pledged Stock.  The Collateral Agent agrees that it will
          ------------------------                                           
not release or otherwise dispose of any of the Pledged Stock or other Collateral
except (a) to the 1996 Trustee or the 1997 Trustee in accordance with the terms
hereof, unless instructed by the applicable Trustee to the contrary, or (b) in
the exercise of its remedies under the terms hereof or (c) to the respective
Pledgor upon satisfaction of all Secured Obligations.

     12.  Obligations of the Collateral Agent.  (a)  Unless the Collateral Agent

has theretofore received a written notice from each of the 1996 Trustee and the
1997 Trustee to the effect that the Senior Subordinated Secured Obligations and
the Junior Subordinated Secured Obligations, respectively, have been paid in
full, if the Collateral Agent shall have resigned as collateral agent hereunder,
not later than the tenth business day following the Senior Payout Date, the
Collateral Agent will deliver at the cost and expense of the Pledgors, directly

full, to the 1997 Trustee), all the certificates representing the Pledged Stock
and all other documents and instruments evidencing or relating to the Collateral
then remaining in the possession of the Collateral Agent, together with any
necessary instruments of assignment or transfer pertaining thereto.  Each
Pledgor agrees to give written notice to each of the 1996 Trustee and the 1997
Trustee of the Senior Payout Date within three business days thereof, and, after
receipt of such notice, the Senior Subordinated Secured Parties (unless the
Senior Subordinated Payout Date has occurred) or (if the Senior Subordinated
Payout Date has occurred) the Junior Subordinated Secured Parties agree to
promptly give written notice to the Collateral Agent requesting delivery of the
Pledged Stock and such other documents and instruments.  In no event shall the
Collateral Agent relinquish control over such certificates representing the
Pledged Stock or any such other documents and instruments after the Senior
Payout Date, except as set forth in this Section or Section 11(c).

     (b)  Unless the 1996 Trustee has theretofore received a written notice from
the 1997 Trustee to the effect that the Junior Subordinated Secured Obligations
have been paid in full, if the 1996 Trustee shall have resigned as successor
collateral agent hereunder, not later than the tenth business day following the
Senior Subordinated Payout Date, the 1996 Trustee will deliver at the cost and
expense of the Pledgors, directly to the successor collateral agent appointed in
accordance with Section 15(h) or, if prior to such tenth business day the 1996
Trustee shall not have received notification of the identity of such successor
collateral agent, to the 1997 Trustee, all the certificates representing the
Pledged Stock and all other documents and instruments evidencing or relating to
the Collateral then remaining in the possession of the 1996 Trustee, together
with any necessary instruments of assignment or transfer pertaining thereto.
Each Pledgor agrees to give written notice to the 1997 Trustee of the Senior
Subordinated Payout Date within three business days thereof, and, after receipt
of such notice, the Junior Subordinated Secured Parties agree to promptly give
written notice to the 1996 Trustee requesting delivery of the Pledged Stock and
such other documents and instruments.  In no event shall the 1996 Trustee
relinquish control over such certificates representing the Pledged Stock or any
such other documents and instruments after the Senior Subordinated Payout Date,
except as set forth in this Section or in Section 11(c).

     (c)  In taking any action hereunder (including the giving of consents and
waivers hereunder) prior to the Senior Payout Date, the Collateral Agent shall
not be obligated to consider the interests of the Subordinated Secured Parties

     13.  Dispositions of Collateral.  Notwithstanding any provision to the
          --------------------------                                       
contrary contained in any agreement, document or instrument in favor of the
Subordinated Secured Parties or to which any of the Subordinated Secured Parties
is a party, the parties hereto agree as follows:

          (a)  Upon the occurrence of any sale, lease, transfer or other
     disposition of any of the Collateral (a "Disposition"), as between the
                                              -----------                  
     Senior Secured Parties and the Subordinated Secured Parties, until the
     Senior Payout Date, all Collateral, including all proceeds thereof and all
     prepayments or distributions in respect thereof, shall be distributed or
     applied or paid to the Administrative Agent, acting on behalf of the Senior
     Secured Parties, for application to the Senior Secured Obligations without
     obtaining any further consent or agreement of the Subordinated Secured
     Parties and in any manner as the Administrative Agent may determine, and
     the Subordinated Secured Parties shall be deemed to have consented to such
     Disposition and no further consent thereto or notice or accounting in
     respect thereof on the part of any such Person shall be required, and,
     until the Senior Payout Date, none of such Collateral shall be distributed
     or paid to (or retained by) the Subordinated Secured Parties for
     application to the Subordinated Secured Obligations, and the Subordinated
     Secured Parties shall not have any right to restrict or permit, or approve
     or disapprove, any Disposition of all or any portion or item of the
     Collateral.

          (b)  Upon a Disposition, as between the Senior Subordinated Secured
     Parties and the Junior Subordinated Secured Parties, after the Senior
     Payout Date and until the Senior Subordinated Payout Date, all Collateral,
     including all proceeds thereof and all prepayments or distributions in
     respect thereof, shall be distributed or applied or paid to the 1996
     Trustee, acting on behalf of the Senior Subordinated Secured Parties, for
     application to the Senior Subordinated Secured Obligations without
     obtaining any further consent or agreement of the Junior Subordinated
     Secured Parties and in any manner as the 1996 Trustee may determine, and
     the Junior Subordinated Secured Parties shall be deemed to have consented
     to such Disposition and no further consent thereto or notice or accounting
     in respect thereof on the part of any such Person shall be required, and
     until the Senior Subordinated Payout Date, none of such Collateral shall be
     distributed or paid to (or retained by) the Junior Subordinated Secured
     Parties for application to the Junior Subordinated Secured Obligations, and
     the Junior Subordinated Secured Parties shall not have any right to
     restrict or permit, or approve or disapprove, any Disposition of all or any
     portion or item of the Collateral.

          (c)  If the Collateral Agent is in possession of any proceeds from any
     Disposition of any Collateral following the Senior Payout Date, the
     Collateral Agent shall deliver such remaining proceeds to: (x) the 1996
     Trustee if any Senior Subordinated Secured Obligations shall be then
     outstanding (which each Pledgor hereby irrevocably consents to); (y) the
     1997 Trustee if any Junior Subordinated Secured Obligations shall be then
     outstanding (which each Pledgor hereby irrevocably
<PAGE>
 
     consents to) and the Collateral Agent has received a written notice from
     the 1996 Trustee to the effect that the Senior Subordinated Secured
     Obligations have been paid in full; and (z) each Pledgor or its successors
     or assigns, if the Collateral Agent has received a written notice from the
     1996 Trustee and the 1997 Trustee to the effect that the Senior
     Subordinated Secured Obligations or the Junior Subordinated Secured
     Obligations, as the case may be, have been paid in full and the 1996
     Trustee and the 1997 Trustee shall agree in writing, or to whomever may be
     lawfully entrusted to receive the same as a court of competent jurisdiction
     shall so direct.

          (d)  The Senior Subordinated Secured Parties and the Junior
     Subordinated Secured Parties will, immediately upon the request of the
     Administrative Agent acting on behalf of the Lenders at any time prior to
     the Senior Payout Date, release or otherwise terminate and discharge their
     respective subordinated liens in any Collateral to the extent such
     Collateral is the subject of a Disposition, and will deliver to the
     Collateral Agent all documents and instruments reasonably deemed by the
     Collateral Agent to be necessary or appropriate in connection therewith.
     In the event that the Collateral Agent, acting on behalf of the Senior
     Secured Parties at any time prior to the Senior Payout Date, settles,
     adjusts or compromises any claim in respect of all or any portion or item
     of Collateral, including, without limitation, any settlement, adjustment or
     compromise made in connection with any bankruptcy, reorganization or
     insolvency proceeding by or against either Pledgor or a Subsidiary of
     either of them, or accepts or is required to accept substitute or
     replacement collateral in exchange for or in lieu of or in full or partial
     settlement of any Collateral, the Subordinated Secured Parties shall be
     bound by any such settlement, adjustment or compromise, and shall,
     immediately upon the request of the Collateral Agent, confirm their consent
     to the same and release any claim that the Subordinated Secured Parties
     might otherwise have in respect of such Collateral; provided that the
     Senior Subordinated Secured Parties shall be granted a lien and security
     interest in any such substitute or replacement Collateral on a second
     priority basis and the Junior Subordinated Secured Parties shall be granted
     a lien and security interest in any such substitute or replacement
     Collateral on a third priority basis, which liens and security interests
     shall constitute subordinated liens.

          (e)  The Junior Subordinated Secured Parties will, immediately upon
     the request of the 1996 Trustee at any time after the Senior Payout Date
     but prior to the Senior Subordinated Payout Date, release or otherwise
     terminate and discharge their respective subordinated liens in any
     Collateral to the extent such Collateral is the subject of a Disposition,
     and will deliver to the Collateral Agent all documents and instruments
     reasonably deemed by the Collateral Agent to be necessary or appropriate in
     connection therewith.  In the event that the Collateral Agent, acting on
     behalf of the Senior Subordinated Secured Parties at any time after the
     Senior Payout Date but prior to the Senior Subordinated Payout Date,
     settles, adjusts or compromises any claim in respect of all or any portion
     or item of Collateral, including, without limitation, any
<PAGE>
 
     settlement, adjustment or compromise made in connection with any
     bankruptcy, reorganization or insolvency proceeding by or against either
     Pledgor or a Subsidiary of either of them, or accepts or is required to
     accept substitute or replacement collateral in exchange for or in lieu of
     or in full or partial settlement of any Collateral, the Junior Subordinated
     Secured Parties shall be bound by any such settlement, adjustment or
     compromise, and shall, immediately upon the request of the Collateral
     Agent, confirm their consent to the same and release any claim that the
     Junior Subordinated Secured Parties might otherwise have in respect of such
     Collateral; provided that the Junior Subordinated Secured Parties shall be
     granted a lien and security interest in any such substitute or replacement
     Collateral on a second priority basis, which lien and security interest
     shall constitute a subordinated lien and security interest.

     14.  Irrevocable Authorization and Instruction to Issuer.  Each Pledgor
          ---------------------------------------------------               
hereby authorizes and instructs the Issuer to comply with any instruction
received by it from the Collateral Agent in writing that (a) states that an
Event of Default has occurred and is continuing and (b) is otherwise in
accordance with the terms of this Agreement, without any other or further
instructions from either Pledgor, and such Pledgor agrees that the Issuer shall
be fully protected in so complying.

     15.  The Collateral Agent. (a)  Appointment.  Each Secured Party hereby
          --------------------       -----------                            
irrevocably designates and appoints the Collateral Agent as the agent of such
Secured Party under this Agreement, and each such Secured Party irrevocably
authorizes the Collateral Agent to take such action on its behalf under the
provisions of this Agreement and to exercise such powers and perform such duties
as are expressly delegated to the Collateral Agent by the terms of this
Agreement, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Collateral Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any other Secured
Party, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against the Collateral Agent.

     (b)  Delegation of Duties.  The Collateral Agent may execute any of its
          --------------------                                              
duties under this Agreement by or through agents or attorneys-in-fact and shall
be entitled to advice of counsel concerning all matters pertaining to such
duties.  The Collateral Agent shall not be responsible for the negligence or
misconduct of any agents or attorneys in-fact selected by it with reasonable
care.

     (c)  Exculpatory Provisions.  None of the Collateral Agent or any of its
          ----------------------                                             
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(1) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement (except for its or such
Person's own gross negligence or willful misconduct) or (2) responsible in any
manner to any of the Secured Parties for any recitals, statements,
representations or warranties made by either Pledgor or any officer thereof
contained in this
<PAGE>
 
Agreement or in any certificate, report, statement or other document referred to
or provided for in, or received by such Collateral Agent under or in connection
with, this Agreement or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or for any failure of either
Pledgor to perform its obligations hereunder.  The Collateral Agent shall not be
under any obligation to any other Secured Party to ascertain or to inquire as to
the observance or performance of any of the agreements contained in, or
conditions of, this Agreement, or to inspect the properties, books or records of
either Pledgor.

     (d)  Reliance by Collateral Agent.  The Collateral 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 Borrowers), independent accountants and other
experts selected by the Collateral Agent.  The Collateral 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 such Collateral Agent.  The Collateral Agent shall be fully justified
in failing or refusing to take any action under this Agreement unless it shall
first receive such advice or concurrence of the Required Lenders (or, at any
time after the Senior Payout Date but prior to the Senior Subordinated Payout
Date, the 1996 Trustee or, at any time after the Senior Payout Date and the
Senior Subordinated Payout Date, the 1997 Trustee), as it deems appropriate or
it shall first be indemnified to its satisfaction by the Senior Secured Parties
and/or the Subordinated Secured Parties against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
such action.  The Collateral Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement in accordance with a
request of the Required Lenders (or, at any time after the Senior Payout Date
but prior to the Senior Subordinated Payout Date, the 1996 Trustee or, at any
time after the Senior Payout Date and the Senior Subordinated Payout Date, the
1997 Trustee), and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Secured Parties and all future holders of
the Loans.

     (e)  Notice of Default.  The Collateral Agent shall not be deemed to have
          -----------------                                                   
knowledge or notice of the occurrence of any Default or Event of Default unless
the Collateral Agent has received notice from a Lender (if the Senior Payout
Date shall not have occurred), the 1996 Trustee (if the Senior Payout Date shall
have occurred but the Senior Subordinated Payout Date shall not have occurred)
or by the 1997 Trustee (if the Senior Payout Date and the Senior Subordinated
Payout Date shall have occurred) 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 the Collateral Agent receives such a
notice, the Collateral Agent shall give notice thereof to the Pledgors and the
Senior Secured Parties (if the Senior Payout Date shall not have occurred), the
Senior Subordinated Secured Parties (if the Senior Payout Date shall have
occurred but the Senior Subordinated Payout Date shall not
<PAGE>
 
have occurred) or the Junior Subordinated Secured Parties (if the Senior Payout
Date and the Senior Subordinated Payout Date shall have occurred).  The
Collateral Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Required Lenders (if the Senior
Payout Date shall not have occurred) or by the 1996 Trustee (if the Senior
Payout Date shall have occurred but the Senior Subordinated Payout Date shall
not have occurred) or by the 1997 Trustee (if the Senior Payout Date and the
Senior Subordinated Payout Date shall have occurred); provided that unless and
                                                      --------                
until the Collateral Agent shall have received such directions, the Collateral
Agent 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 Senior Secured Parties (if the
Senior Payout Date shall not have occurred), the Senior Subordinated Secured
Parties (if the Senior Payout Date shall have occurred but the Senior
Subordinated Payout Date shall not have occurred) or the Junior Subordinated
Secured Parties (if the Senior Payout Date and the Senior Subordinated Payout
Date shall have occurred).

     (f)  Non-Reliance on Collateral Agent.  Each other Secured Party expressly
          --------------------------------                                     
acknowledges that none of the Collateral 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 the Collateral Agent
hereinafter taken shall be deemed to constitute any representation or warranty
by the Collateral Agent to any Secured Party.  Except for notices, reports and
other documents expressly required to be furnished to the Secured Parties by the
Collateral Agent hereunder, the Collateral Agent shall not have any duty or
responsibility to provide any other Secured Party with any credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of either Pledgor which may come
into the possession of the Collateral Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates.

     (g)  Collateral Agent in Its Individual Capacity.  The Collateral Agent and
          -------------------------------------------                           
its Affiliates may make loans to, accept deposits from and generally engage in
any kind of business with either Pledgor as though the Collateral Agent were not
the Collateral Agent hereunder.

     (h)  Successor Collateral Agent.  The Collateral Agent may resign as
          --------------------------                                     
Collateral Agent upon 10 days' notice to the Lenders.  If the Collateral Agent
shall resign as Collateral Agent under this Agreement, then the Required Lenders
shall appoint from among the Lenders a successor Collateral Agent, which
successor agent shall succeed to the rights, powers and duties of such
Collateral Agent hereunder.  Upon the Senior Payout Date, the Collateral Agent
shall automatically be deemed to have resigned as Collateral Agent under this
Agreement, and (if the Senior Subordinated Payout Date has not occurred) the
1996 Trustee shall appoint a successor collateral agent for the Subordinated
Secured Parties within 10 days after its receipt of notice from the Collateral
Agent of such resignation or, in the absence of such appointment, the 1996
Trustee shall automatically be appointed as successor collateral agent on the
tenth day after its receipt of such notice, which successor collateral agent
<PAGE>
 
(whether it shall be the 1996 Trustee or any other Person) shall succeed to the
rights, powers and duties of such Collateral Agent hereunder.  After the Senior
Payout Date and upon the Senior Subordinated Payout Date, the 1996 Trustee, or
its designee, appointed in accordance with the preceding sentence, shall
automatically be deemed to have resigned as successor Collateral Agent under
this Agreement, and the 1997 Trustee shall appoint a successor collateral agent
for the Junior Subordinated Secured Parties within 10 days after its receipt of
notice from the Collateral Agent of such resignation or, in the absence of such
appointment, the 1997 Trustee, or its designee, shall automatically be appointed
as successor collateral agent on the tenth day after its receipt of such notice,
which successor collateral agent shall succeed to the rights, powers and duties
of such Collateral Agent hereunder.  Effective upon any such appointment, the
term "Collateral Agent" shall mean such successor agent, and such former
Collateral Agent's rights, powers and duties as Collateral Agent shall be
terminated, without any other or further act or deed on the part of such former
Collateral Agent or any of the parties to this Agreement or any Secured Party.
After any retiring Collateral Agent's resignation as Collateral Agent, the
provisions of this Section 15 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Collateral Agent under this Agreement.
Anything in this Agreement to the contrary notwithstanding, in the event of an
automatic resignation of the Collateral Agent in the circumstances described in
the third or fourth sentence of this paragraph, such resignation shall become
effective upon the appointment of a successor collateral agent in accordance
with the provisions of such third or fourth sentence, as the case may be, and,
thereafter, the sole obligation of the Collateral Agent hereunder shall be to
make delivery of the certificates representing the Pledged Stock to such
successor collateral agent or, if the Collateral Agent shall not have received
from the 1996 Trustee a written notice of the appointment of a successor
collateral agent other than the 1996 Trustee, to the 1996 Trustee, or, if the
Collateral Agent shall not have received from the 1997 Trustee a written notice
of the appointment of a successor collateral agent other than the 1997 Trustee,
to the 1997 Trustee, as the case may be.

     16.  Collateral Agent's Appointment as Attorney-in-Fact.  (a)  Each Pledgor
          --------------------------------------------------                    
hereby irrevocably constitutes and appoints the Collateral Agent and any officer
or agent of the Collateral Agent, with full power of substitution, as its true
and lawful attorney-in-fact with full irrevocable power and authority in the
place and stead of such Pledgor and in the name of such Pledgor or in the
Collateral Agent's own name, from time to time in the Collateral Agent's
discretion, for the purpose of carrying out the terms of this Agreement, to take
any and all appropriate action and to execute any and all documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Agreement, including, without limitation, any financing statements,
endorsements, assignments or other instruments of transfer.

     (b)  Each Pledgor hereby ratifies all that said attorneys shall lawfully do
or cause to be done pursuant to the power of attorney granted in Section 16(a).
All powers, authorizations and agencies contained in this Agreement are coupled
with an interest and are irrevocable until this Agreement is terminated and the
security interests created hereby are released.
<PAGE>
 
     17.  Duty of Collateral Agent.  The Collateral Agent's sole duty with
          ------------------------                                        
respect to the custody, safekeeping and physical preservation of the Collateral
in its possession, under Section 9-207 of the Code or otherwise, shall be to
deal with it in the same manner as the Collateral Agent deals with similar
securities and property for its own account, except that the Collateral Agent
shall have no obligation to invest funds held in any Collateral Account and may
hold the same as demand deposits.  Neither the Collateral Agent, any Lender, the
Trustees, any Holder nor any of their respective directors, officers, employees
or agents shall be liable for failure to demand, collect or realize upon any of
the Collateral or for any delay in doing so or shall be under any obligation to
sell or otherwise dispose of any Collateral upon the request of either Pledgor
or any other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof.

     18.  Execution of Financing Statements.  Pursuant to Section 9-402 of the
          ---------------------------------                                   
Code, each Pledgor authorizes the Collateral Agent to file financing statements
with respect to the Collateral without the signature of such Pledgor in such
form and in such filing offices as the Collateral Agent reasonably determines
appropriate to perfect the security interests of the Collateral Agent under this
Agreement.  A carbon, photographic or other reproduction of this Agreement shall
be sufficient as a financing statement for filing in any jurisdiction.

     19.  Notices.  All notices, requests and demands to or upon the Company,
          -------                                                            
either Pledgee or either Pledgor to be effective shall be in writing (or by
telex, fax or similar electronic transfer confirmed in writing) and shall be
deemed to have been duly given or made (1) when delivered by hand or (2) if
given by mail, two days after being deposited in the mails by certified mail,
return receipt requested, or (3) if by telex, fax or similar electronic
transfer, when sent and receipt has been confirmed, addressed to such party at
its address or transmission number for notices provided under its signature
below.  Any party hereto may change their addresses and transmission numbers for
notices by notice in the manner provided in this Section.

     20.  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.

     21.   Amendments in Writing; No Waiver; Cumulative Remedies.  (a)  None of
           -----------------------------------------------------               
the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except by a written instrument executed by each Pledgor,
the Collateral Agent and, if the Senior Payout Date shall not have occurred, the
Administrative Agent or, if the Senior Payout Date shall have occurred but the
Senior Subordinated Payout Date shall not have occurred, the 1996 Trustee or, if
the Senior Payout Date and the Senior Subordinated Payout Date shall have
occurred, the 1997 Trustee, provided that any provision of this Agreement may be
                            --------                                            
waived by the Collateral Agent and, if the Senior Payout Date shall not have
<PAGE>
 
occurred, the Administrative Agent or, if the Senior Payout Date shall have
occurred but the Senior Subordinated Payout Date shall not have occurred, the
1996 Trustee or, if the Senior Payout Date and the Senior Subordinated Payout
Date shall have occurred, the 1997 Trustee in a letter or agreement executed by
the Collateral Agent or by telex or facsimile transmission from the Collateral
Agent and, if the Senior Payout Date shall not have occurred, the Administrative
Agent or, if the Senior Payout Date shall have occurred but the Senior
Subordinated Payout Date shall not have occurred, the 1996 Trustee or, if the
Senior Payout Date and the Senior Subordinated Payout Date shall have occurred,
the 1997 Trustee and, provided, further, that no such waiver, amendment,
                      --------  -------                                 
supplement or other modification which materially and adversely affects: (x) any
Senior Subordinated Secured Party shall be effective unless it shall have been
consented to by the 1996 Trustee or (y) any Junior Subordinated Secured Party
shall be effective unless it shall have been consented to by the 1997 Trustee.

     (b)  Neither the Collateral Agent nor any Secured Party shall by any act
(except by a written instrument pursuant to Section 21(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Default or Event of Default or in any
breach of any of the terms and conditions hereof.  No failure to exercise, nor
any delay in exercising, on the part of the Collateral Agent or any Secured
Party, any right, power or privilege hereunder shall operate as a waiver
thereof.  No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege.  A waiver by the Collateral Agent or any
Secured Party of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Collateral Agent or such
Secured Party would otherwise have on any future occasion.

     (c)  The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

     22.  Transfer of Pledged Stock to the Company.  Notwithstanding anything in
          ----------------------------------------                              
this Agreement to the contrary, the Pledgor shall be entitled to transfer the
Pledged Stock to the Company, provided that such transfer shall be made
                              --------                                 
expressly subject to the terms and conditions of this Agreement and that,
simultaneously with such transfer, the Company shall expressly assume, pursuant
to a written instrument in form and substance satisfactory to the Collateral
Agent, the obligations of the Pledgors hereunder and, pursuant to the terms of
such instrument, this Agreement shall be amended in a manner reasonably
acceptable to the Administrative Agent (if the Senior Payout Date shall not have
occurred), the 1996 Trustee (if the Senior Payout Date shall have occurred but
the Senior Subordinated Payout Date shall not have occurred) or the 1997 Trustee
(if the Senior Payout Date and the Senior Subordinated Payout Date shall have
occurred) to reflect such transfer, including the confirmation and reaffirmation
of the grant of first, second and third priority Liens to the Senior Secured
Parties, Senior Subordinated Secured Parties and Junior Subordinated Secured
Parties, respectively, with respect to the Pledged Stock and, provided, further,
                                                              --------  ------- 
that no such amendment which materially and adversely affects: (x) any Senior
Subordinated Secured
<PAGE>
 
Party shall be effective unless it shall have been consented to by the 1996
Trustee or (y) any Junior Subordinated Secured Party shall be effective unless
it shall have been consented to by the 1997 Trustee.

     23.  Section Headings.  The section headings used in this Agreement are for
          ----------------                                                      
convenience of reference only and are not to affect the construction hereof or
be taken into consideration in the interpretation hereof.

     24.  Trustees Not Responsible for Recitals, Etc.  The recitals hereto shall
          -------------------------------------------                           
not be taken as those of the Trustees or either of them, and neither of the
Trustees assumes any responsibility for their correctness.  Neither of the
Trustees makes any representations as to the title of the Pledgors to the
Pledged Stock, or the title to, or validity or genuineness of, any Collateral at
any time pledged and deposited with the Collateral Agent hereunder, or as to the
validity or sufficiency of this Agreement.

     25.  Successors and Assigns.  This Agreement shall be binding upon the
          ----------------------                                           
successors and assigns of the Company and shall inure to the benefit of the
Collateral Agent and the Secured Parties and their successors and assigns.

     26.  Governing Law.  This Agreement shall be governed by, and construed and
          -------------

last four fiscal quarters for which financial statements are available at the

agreement requiring the calculation of EBITDA for purposes of Section 4.6 and,
in each case, with respect to which financial results on a consolidated basis
with the Company have not been made available for an entire fiscal quarter;
plus (ii) in connection with any such acquisition, projected quantifiable
improvements in operating results due to an established program of cost
reductions (consistent with the cost reductions actually achieved by the Company

an Officers' Certificate filed with the Trustee (calculated on a pro forma
basis for the Acquisition EBITDA Period as if the program had been implemented
at the beginning of the Acquisition EBITDA Period), without giving effect to any

                                   ARTICLE 2.

                                   THE NOTES

Section 2.1.   Dating; Incorporation of Form in Indenture.
               ------------------------------------------ 

          The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A which is incorporated in and made part of
this Indenture.  The Notes may have notations, legends or endorsements required
by law, stock exchange rule or usage.  The Company may use "CUSIP" numbers in
issuing the Notes.  The Company shall approve the form of the Notes.  Each Note
shall be dated the date of its authentication.

          The terms and provisions contained in the form of the Notes annexed
hereto as Exhibit A, shall constitute, and are hereby expressly made, a part of
this Indenture and, to the extent applicable, the Company and the Trustee, by
their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby.

          The Notes shall be issued in the form of one or more permanent global
notes in registered form, substantially in the form set forth in Exhibit A
("Global Notes"), deposited with the Trustee, as custodian for the Depository,
duly executed by the Company and authenticated by the Trustee as hereinafter
provided and shall bear the legend set forth on Exhibit B.  The aggregate
princi pal amount of any Global Note may from time to time be increased or
decreased by adjustments made on the records of the Trustee, as custodian for
the Depository, as hereinafter provided.

Section 2.2.   Execution and Authentication.
               ---------------------------- 

          The aggregate principal amount of Notes which may be authenticated and
delivered under the Indenture is $120,000,000.

                                       29
<PAGE>
 
          The Notes shall be executed on behalf of the Company by two Officers
of the Company or an Officer and an Assistant Secretary of the Company.  Such
signatures may be either manual or facsimile.  The Company's seal shall be
impressed, affixed, imprinted or reproduced on the Notes and may be in facsimile
form.

          If an Officer whose signature is on a Note no longer holds that office
at the time the Trustee authenticates the Note or at anytime thereafter, the
Note shall be valid nevertheless.

          A Note shall not be valid until the Trustee manually signs the
certificate of authentication on the Note.  Such signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

          The Trustee or an authenticating agent shall authenticate Notes for
original issue in the aggregate principal amount of $120,000,000 upon a Company
Request.  The aggregate principal amount of Notes outstanding at any time may
not exceed such amount except as provided in Section 2.7 hereof. The Notes shall
be issuable only in registered form without coupons and only in denominations of
$1,000 and integral multiples thereof.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes.  Unless limited by the terms of such appointment,
an authenticating agent may authenticate Notes whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  Such authenticating agent shall have the same
right as the Trustee in dealing with the Company or an Affiliate.

Section 2.3.   Registrar and Paying Agent.
               -------------------------- 

          The Company shall appoint a registrar, which shall maintain an office
or agency where Notes may be presented for registration of transfer or for
exchange ("Registrar"), and a paying agent, which shall maintain an office or
agency located in the Borough of Manhattan, City of New York, State of New York
where Notes may be presented for payment ("Paying Agent") and shall maintain

                                       30
<PAGE>
 
an office or agency where notices and demands to or upon the Company in respect
of the Notes and this Indenture may be served. The Registrar shall keep a
register of the Notes and of their transfer and exchange. The Company may
appoint one or more co-registrars and one or more additional paying agents.
Neither the Company nor any Affiliate may act as Paying Agent. The Company may
change any Paying Agent, Registrar or co-registrar without notice to any
Noteholder.

          The Company shall enter into an appropriate agency agreement with any
Registrar or Paying Agent not a party to this Indenture.  The agreement shall
implement the provisions of this Indenture that relate to such Agent.  The
Company shall notify the Trustee of the name and address of any such Agent.  If
the Company fails to maintain a Registrar or Paying Agent, or agent for service
of notices and demands, or fails to give the foregoing notice, the Trustee
shall act as such and shall be entitled to appropriate compensation pursuant to
Section 7.7.  The Company initially appoints the Trustee as Registrar, Paying
Agent and agent for service of notices and demands in connection with the Notes.

                                       31
<PAGE>
 
Section 2.4.   Paying Agent to Hold Money in Trust.
               ----------------------------------- 

          On or before each due date of the principal and interest on any Notes,
the Company shall deposit with the Paying Agent a sum sufficient to pay such
principal and interest so becoming due.  Each Paying Agent shall hold in trust
for the benefit of the Noteholders or the Trustee all money held by the Paying
Agent for the payment of principal of or interest on the Notes (whether such
money has been paid to it by the Company or any other obligor on the Notes), and
the Company and the Paying Agent shall notify the Trustee of any default by the
Company (or any other obligor on the Notes) in making any such payment. Money
held in trust by the Paying Agent need not be segregated except as required by
law and in no event shall the Paying Agent be liable for any interest on any
money received by it hereunder.  The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee and the Trustee, may at any
time during the continuance of any Payment Default, upon written request to a
Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums
so held in trust by such Paying Agent together with a complete accounting of
such sums.  Upon doing so, the Paying Agent shall have no further liability for
the money delivered to the Trustee.

Section 2.5.   Noteholder Lists.
               ---------------- 

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Noteholders.  If the Trustee is not the Registrar, the Company shall furnish to
the Trustee on or before each January 1 and July 1 in each year, and at such
other times as the Trustee may request in writing, a list in such form and as of
such date as the Trustee may reasonably require of the names and addresses of
Noteholders, including the aggregate principal amount of Notes held by each such
Noteholder.

Section 2.6.   Transfer and Exchange.
               --------------------- 

          When a Note is presented to the Registrar with a request to register
the transfer thereof, the Registrar shall register the transfer as requested if
the require-

                                       32
<PAGE>
 
ments of applicable law are met and, when Notes are presented to the
Registrar with a request to exchange them for an equal principal amount of Notes
of other authorized denominations, the Registrar shall make the exchange as
requested provided that every Note presented or surrendered for registration of
transfer or exchange shall be duly endorsed or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Registrar
duly executed by the Holder thereof or his attorney, duly authorized in writing.
To permit registration of transfers and exchanges, upon surrender of any Note
for registration of transfer or exchange at the office or agency maintained
pursuant to Section 2.3 hereof, the Company shall issue and execute and the
Trustee shall authenticate and make available for delivery Notes at the
Registrar's request in the name of the transferee or Holder, as the case may be,
designated by the Registrar. Any exchange or transfer shall be without any
service charge to the Noteholder, except that the Company may require payment by
the Holder of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation to a transfer or exchange, but this provision
shall not apply to any exchange pursuant to Section 2.9, 3.6 or 8.5 hereof. The
Registrar shall not be required to register transfers of Notes or to exchange
Notes for a period of 15 days before the day of mailing of the notice of
redemption of any Notes to be redeemed. The Registrar shall not be required to
exchange or register transfers of any Notes called or being called for
redemption in whole or in part, except the unredeemed portion of any Note being
redeemed in part.

          Any Holder of the Global Note shall, by acceptance of such Global
Note, agree that transfers of the beneficial interests in such Global Note may
be effected only through a book entry system maintained by the Holder of such
Global Note (or its agent), and that ownership of a beneficial interest in the
Global Note shall be re quired to be reflected in a book entry.

          Neither the Trustee nor the Registrar shall have any duty to monitor
the Company's compliance with or have any responsibility with respect to the
Company's compliance with any Federal or state securities laws.

Section 2.7.  Replacement Notes.
              ----------------- 

                                       33
<PAGE>
 
          If a mutilated Note is surrendered to the Registrar or Trustee or if
the Holder of a Note presents evidence to the satisfaction of the Company and
the Trustee that the Note has been lost, destroyed or wrongfully taken and of
the ownership thereof, the Company shall issue and the Trustee shall
authenticate a replacement Note if the requirements of Section 8-405 of the New
York Uniform Commercial Code as in effect on the date of this Indenture are met.
An indemnity bond may be re quired by the Company or the Trustee that is
sufficient in the judgment of the Company and the Trustee to protect the
Company, the Trustee or any Agent from any loss which any of them may suffer if
a Note is replaced. The Company and the Trustee each may charge for its
expenses (including reasonable attorneys' fees and expenses) in replacing a
Note. Every replacement Note is an additional obligation of the Company.

Section 2.8.  Outstanding Notes.
              ----------------- 

          Notes outstanding at any time are all Notes authenticated by the
Trustee except for those cancelled by it, those delivered to it for
cancellation, and those described in this Section 2.8 as not outstanding.

          If a Note is replaced pursuant to Section 2.7, it ceases to be
outstanding until the Company and the Trustee receive proof satisfactory to each
of them that the replaced Note is held by a bona fide purchaser.

          If a Paying Agent holds on a Redemption Date or Maturity Date money
sufficient to pay the principal of, premium, if any, and all accrued interest on
Notes payable on that date and is not prohibited from paying such money to the
Holders thereof pursuant to the terms of this Indenture, then on and after that
date such Notes cease to be outstanding and interest on them ceases to accrue.

          Subject to Section 13.6, a Note does not cease to be outstanding
solely because the Company or an Affiliate holds the Note.

Section 2.9.  Temporary Notes.
              --------------- 

                                       34
<PAGE>
 
          Until definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes.  Temporary Notes shall be
substantially in the form, and shall carry all rights, benefits and privileges,
of definitive Notes but may have variations that the Company considers
appropriate for temporary Notes. Without unreasonable delay, the Company shall
prepare and the Trustee shall authenticate definitive Notes in exchange for
temporary Notes presented to it.

Section 2.10.  Cancellation.
               ------------ 

          The Company at any time may deliver Notes to the Trustee for
cancellation.  The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment.  The Trustee
shall cancel and retain or, upon written request of the Company, return to the
Company, in accordance with its normal practice, all Notes surrendered for
transfer, exchange, payment or cancellation.  Subject to Section 2.7 hereof, the
Company may not issue new Notes to replace Notes in respect of which it has
previously paid all principal, premium and interest accrued thereon, or
delivered to the Trustee for cancellation.

                                       35
<PAGE>
 
Section 2.11.  Defaulted Interest.
               ------------------ 

          If the Company defaults in a payment of interest on the Notes, it
shall pay the defaulted amounts, plus (to the extent permitted by law) any
interest payable on defaulted amounts pursuant to Section 4.1 hereof, to the
persons who are Noteholders on a subsequent special record date.  The Company
shall fix the special record date and payment date in a manner satisfactory to
the Trustee and provide the Trustee at least 20 days notice of the proposed
amount of default interest to be paid and the special payment date.  At least 15
days before the special record date, the Company shall mail or cause to be
mailed to each Noteholder at his address as it appears on the Notes register
maintained by the Registrar a notice that states the special record date, the
payment date (which shall be not less than five nor more than ten days after the
special record date), and the amount to be paid.  In lieu of the foregoing
procedures, the Company may pay defaulted interest in any other lawful manner
satisfactory to the Trustee.

Section 2.12.  Deposit of Moneys.
               ----------------- 

          Prior to 10:00 a.m., New York City time, on each Interest Payment Date
and Maturity Date, the Company shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date or Maturity Date, as the case may be, in a timely
manner which permits the Trustee to remit payment to the Holders on such
Interest Payment Date or Maturity Date, as the case may be.  The principal and
interest on Global Notes shall be payable to the Depository or its nominee, as
the case may be, as the sole registered owner and the sole holder of the Global
Notes represented thereby.  The principal and interest on Physical Notes shall
be payable at the office of the Paying Agent.

Section 2.13.  CUSIP Number.
               ------------ 

          The Company in issuing the Notes may use a "CUSIP" number(s), and if
so, the Trustee shall use the CUSIP number(s) in notices of redemption or
exchange as a convenience to Holders, provided that any such notice may 
                                      --------                               

                                       36
<PAGE>
 
state that no representation is made as to the correctness or accuracy of the
CUSIP number(s) printed in the notice or on the Notes, and that reliance may be
placed only on the other identification numbers printed on the Notes. The
Company will promptly notify in writing the Trustee of any such CUSIP number
used by the Company in connection with the Notes and any change in such CUSIP
number.

Section 2.14.  Book-Entry Provisions for Global Notes.
               -------------------------------------- 

          (a)  The Global Notes shall (i) be registered in the name of the
Depository or the nominee of such Depository, (ii) be delivered to the Trustee
as custodian for such Depository and (iii) bear the legend as set forth in
Exhibit B.

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

          (b)  Transfers of Global Notes shall be limited to transfer in whole,
but not in part, to the Depository, its successors or their respective nominees.
Certificated Notes (the "Physical Notes") shall be transferred to all
beneficial owners in exchange for their beneficial interests in Global Notes if
(i) the Depository notifies the Company that it is unwilling or unable to
continue as Depository for any Global Note and a successor depositary is not
appointed by the Company within 90 days of such notice or (ii) an Event of
Default has occurred and is continuing and the Registrar has received a written
request from the Depository to issue Physical Notes.

                                       37
<PAGE>
 
          (c)  In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Note to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Company
shall execute, and the Trustee shall upon receipt of a written order from the
Company authenticate and make available for delivery, one or more Physical Notes
of like tenor and amount.

          (d)  In connection with the transfer of Global Notes as an entirety to
beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to
be surrendered to the Trustee for cancellation, and the Company shall execute,
and the Trustee shall authenticate and deliver, to each beneficial owner
identified by the Depository in writing in exchange for its beneficial interest
in the Global Notes, an equal aggregate principal amount of Physical Notes of
authorized denominations.

          (e)  The Holder of any Global Note may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture, the Notes or the Guarantees.


                                   ARTICLE 3.

Section 3.1.  Notices to Trustee.
              ------------------ 

          If the Company elects to redeem Notes pursuant to Section 3.7 hereof,
(i) at least 60 days prior to the Redemption Date in the case of a partial
redemption, (ii) at least 45 days prior to the Redemption Date in the case of a
total redemption or (iii) during such other period as the Trustee may agree to
in writing, the Company shall notify the Trustee in writing of the Redemption
Date, the principal amount of Notes to be redeemed and the redemption price,
and deliver to the Trustee an Officers' Certificate 

                                       38
<PAGE>

Section 3.7 hereof, as appropriate.

Section 3.2.   Selection by Trustee of Notes to Be Re deemed.
               --------------------------------------------- 

          In the event that fewer than all of the Notes are to be redeemed, the
Trustee shall select the Notes to be redeemed, if the Notes are listed on a
national securities exchange, in accordance with the rules of such exchange or,
if the Notes are not so listed, on either a pro rata basis or by lot, or such
other method as it shall deem fair and appropriate; provided, however, that if a
                                                    --------  -------           
partial redemption is made with the proceeds of a Public Equity Offering,
selection of the Notes or portion thereof for redemption shall be made by the
Trustee on a pro rata basis, unless such a method is prohibited by law or by the
             --- ----                                                           
rules of such national securities exchange.  The Trustee shall promptly notify
the Company of the Notes selected for redemption and, in the case of any Notes
selected for partial redemption, the principal amount thereof to be redeemed.
The Trustee may select for redemption portions of the principal of the Notes
that have denominations larger than $1,000.  Notes and portions thereof the
Trustee selects shall be redeemed in amounts of $1,000 or whole multiples of
$1,000. For all purposes of this Indenture unless the context otherwise
requires, provisions of this Indenture that apply to Notes called for redemption
also apply to portions of Notes called for redemption.

Section 3.3.  Notice of Redemption.
              -------------------- 

          At least 30 days, but no more than 60 days, before a Redemption Date,
the Company shall mail, or cause to be mailed, a notice of redemption by first-
class mail to each Holder of Notes to be redeemed at his or her last address as
the same appears on the registry books maintained by the Registrar pursuant to
Section 2.3 hereof.

          The notice shall identify the Notes to be redeemed (including the
CUSIP numbers thereof) and shall state:

                                       39
<PAGE>
 
     (1) the Redemption Date;

     (2) the redemption price;

     (3) if any Note is being redeemed in part, the portion of the principal
amount of such Note to be redeemed and that, after the Redemption Date and upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion will be issued;

     (4) the name and address of the Paying Agent;

     (5) that Notes called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

     (6) that unless the Company defaults in making the redemption payment,
interest on Notes called for redemption ceases to accrue on and after the
Redemption Date;

     (7) the paragraph of Section 3.7 hereof pursuant to which the Notes called

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

          Once the notice of redemption described in Section 3.3 is mailed,
Notes called for redemption become due and payable on the Redemption Date and at
the redemption price, including any premium, plus interest accrued to the
Redemption Date.  Upon surrender to the Paying Agent, such Notes shall be paid
at the redemption price, including any premium, plus interest accrued to the
Redemption Date, provided that if the Redemption Date is after a regular

interest payment record date and on or prior to the Interest Payment Date, the
accrued interest shall be payable to the Holder of the redeemed Notes registered
on the relevant record date, and provided, further, that if a Redemption Date is
                                 --------  -------

funds money sufficient to pay the redemption price of and accrued interest on
all Notes to be redeemed on that date other than Notes or portions thereof
called for redemption on that date which have been delivered by the Company to
the Trustee for cancellation.

          On and after any Redemption Date, if money sufficient to pay the
redemption price of and accrued interest on Notes called for redemption shall
have been made available in accordance with the preceding paragraph and payment
thereof is not prohibited pursuant to the terms of this Indenture, the Notes
called for redemption will cease to accrue interest and the only right of the
Holders of such Notes will be to receive payment of the redemption price of and,
subject to the first proviso in Section 3.4, accrued and unpaid interest on such
Notes to the Redemption Date.  If any Note called for redemption shall not be so
paid, interest will be paid, from the Redemption Date until such redemption
payment is made, on the unpaid principal of the Note and any interest not paid
on such unpaid principal, in each case, at the rate

the Company hereby expressly waives all benefit or advantage of any such law,

such Defaults or Events of Default of which he or she may have knowledge and
what action the Company is taking or proposes to take with respect thereto) and
that to the best of his or her knowledge no event has occurred and remains in
existence by reason of which payments on account of the principal of or

          The Company will not, and will not permit any Restricted Subsidiary of
the Company to, directly or indirectly, incur any Indebtedness (including

Indebtedness which is the subject of a determination under this provision is
Acquired Indebtedness, or Indebtedness incurred in connection with the
simultaneous acquisition of any Person, business, property or assets, then such

as a consequence of the incurrence of such Indebtedness.

          Notwithstanding the foregoing, the Company and its Restricted

                                               --------                       
not incur any Permitted Indebtedness, without meeting the Indebtedness
incurrence provisions of the preceding paragraph, that ranks pari passu or
                                                             ---- -----

would be entitled to incur or assume Indebtedness under Section 4.6 hereof in

                                       46
<PAGE>
 
the aggregate principal amount equal to the aggregate liqui dation value of the
Preferred Stock to be issued; provided, however, that any Restricted Subsidiary
                              --------  -------

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

Indebtedness or as permitted in Section 4.12 hereof) or (ii) permit any of its
Restricted Subsidiaries to issue any Capital Stock, other than to the Company or
a Wholly-Owned Subsidiary of the Company.  The foregoing restrictions shall not
apply to an Asset Sale made in compliance with Section 4.10 hereof or the

     continuing at the time of or immediately after giving effect to such
     Restricted Payment;

          (b)  immediately after giving pro forma effect to such Restricted
                                        --- -----                          
     Payment, the Company could incur $1.00 of additional Indebtedness (other
     than Permitted Indebtedness) under Section 4.6 hereof; and

          (c)  immediately after giving effect to such Restricted Payment, the
     aggregate of all Restricted Payments declared (except to the extent not
     made on the payment date) or made after the Issue Date does not exceed the
     sum of (1) 50% of the cumulative Consolidated Net Income of the Company
     subsequent to the Issue Date (or minus 100% of any cumulative deficit in

     value of securities or other property received by the Company from the
     issue or sale, after the Issue Date, of Capital Stock (other than

     for Capital Stock (other than Dis qualified Capital Stock) of the Company
     which has been so converted or exercised or exchanged, as the case may be,
     and (3) $3,000,000. For purposes of determining under this clause (c) the
     amount expended for Restricted Payments, cash distributed shall be valued
     at the face amount thereof and property other than cash shall be valued at
     its fair market value.

          Notwithstanding the foregoing, the provisions of this Section 4.9

date of declaration thereof, if at such date of declaration such payment would
comply with the provisions of this Indenture, (ii) the retirement of any shares

(other than to a Subsidiary of the Company) of other shares of Capital Stock of
the Company (other than Disqualified Capital Stock), (iii) the redemption or
retirement of Indebtedness of the Company subordinated to the Notes in exchange
for, by conversion into, or out of the Net Proceeds of, a substantially
concurrent sale or incurrence of Indebtedness (other than any Indebtedness owed
to a Subsidiary) of the Company that is contractually subordinated in right of
payment to the Notes to at least the same extent as the subordinated
Indebtedness being redeemed or retired, (iv) the retirement of any shares of
Disqualified Capital Stock by conversion into, or by exchange for, shares of
Disqualified Capital Stock, or out of the Net Proceeds of the substantially

provided, however, that the aggregate amount of all such payments under this
- --------  -------
clause (vi) does not exceed $2,000,000 in the aggregate, exclusive of amounts
funded by insurance proceeds; and provided, further, that with respect to clause
                                  --------  -------
(vi) (other than with respect to payments funded by insurance proceeds) no
Default or Event of Default shall have occurred and be continuing at the time of
any such distribution or payment or will occur immediately after giving effect
to any such distribution or payment; and provided, further, that, in determining
                                         --------  -------

Section 4.10.  Limitation on Certain Asset Sales.
               --------------------------------- 

          (a)  The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company or its
Restricted Subsidiaries, as the case may be, receives consideration at the time
of such sale or other disposition at least equal to the fair market value
thereof (as determined for Asset Sales other than eminent domain, condemnation
or similar government proceedings in good faith by the Company's board of
directors, and evidenced by a board resolution); (ii) not less than 85% of the
consideration received by the Company or its Subsidiaries, as the case may be,
is in the form of cash or Temporary Cash Investments; and (iii) the Asset Sale
Proceeds received by the Company or such Restricted Subsidiary are applied (a)
first, to the extent the Company elects, or is required, to prepay, repay or
purchase debt under any then existing Senior Indebtedness of the Company or any
Restricted Subsidiary within 180 days following the receipt of the Asset Sale
Proceeds from any Asset Sale; (b) second, to the extent of the balance of Asset
Sale Proceeds after application as described above, to the extent the Company
elects, to an investment in assets (including Capital Stock or other securities
purchased in connection with the acquisition of Capital Stock or property of
another Person) used or useful in businesses similar or ancillary to the
business of the Company or Restricted Subsidiary as conducted at the time of
such Asset Sale, provided that such investment occurs or the Company or a
Restricted Subsidiary enters into contractual commitments to make such
investment, subject only to customary conditions (other than the obtaining of
financing), on or prior to the 181st day following receipt of such Asset Sale
Pro ceeds (the "Reinvestment Date") and Asset Sale Proceeds contractually
committed are so applied within 270 days following the receipt of such Asset
Sale Proceeds; and (c) third, if on the Reinvestment Date with respect to any
Asset Sale, the Available Asset Sale Proceeds exceed $10 million, the Company
shall apply an amount equal to such Available Asset Sale Proceeds to an offer to
repurchase the Notes, or any future Indebtedness ranking pari passu with the
Notes, which Indebtedness contains similar provisions requiring the Company to
repurchase such Indebtedness at a purchase price in cash equal to 100% of the
principal amount thereof plus accrued and unpaid interest, if any, to the date
of repurchase (an "Excess Proceeds Offer"); provided, however, that prior to
making

                                       50
<PAGE>
 
any such Excess Proceeds Offer, the Company may, to the extent required pursuant
to the terms of Indebtedness outstanding as of the Issue Date, offer to use such
Available Asset Sale Proceeds to repurchase and use all or a portion of such
Available Asset Sale Proceeds to repurchase such Indebtedness. If an Excess
Proceeds Offer is not fully subscribed, the Company may retain the portion of
the Available Asset Sale Proceeds not required to repurchase Notes for general
corporate purposes. If the aggregate principal amount of Notes tendered pursuant
to such Excess Proceeds Offer is more than the amount of the Available Asset
Sale Proceeds, the Notes tendered will be repurchased on a pro rata basis or by
such other method as the Trustee shall deem fair and appropriate.

          (b)  If the Company is required to make an Excess Proceeds Offer, the
Company shall mail, within 30 days following the Reinvestment Date (or within
120 days following the Reinvestment Date if the Company is required to make an
offer to purchase Indebtedness (other than the Notes) outstanding as of the
Issue Date), a notice to the Holders stating, among other things: (1) that such
Holders have the right to require the Company to apply the Available Asset Sale
Proceeds to repurchase such Notes at a purchase price in cash equal to 100% of
the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase; (2) the purchase date (the "Purchase Date"), which shall be
no earlier than 30 days and not later than 60 days from the date such notice is
mailed; (3) the instructions, deter mined by the Company, that each Holder must
follow in order to have such Notes repurchased; and (4) the calculations used
in determining the amount of Available Asset Sale Proceeds to be applied to the
repurchase of such Notes.  The Excess Proceeds Offer shall remain open for a
period of 20 Business Days following its commencement (the "Offer Period").  The
notice, which shall govern the terms of the Excess Proceeds Offer, shall state:

          (1)  that the Excess Proceeds Offer is being made pursuant to this
     Section 4.10 and the length of time the Excess Proceeds Offer will remain
     open;

          (2)  the purchase price and the Purchase Date;

          (3)  that any Note not tendered or accepted for 

                                       51
<PAGE>
 
               payment will not be purchased and will continue to accrue 
     interest;

          (4)  that any Note accepted for payment pursuant to the Excess
     Proceeds Offer shall cease to accrue interest on and after the Purchase
     Date so long as payment thereof is not prohibited pursuant to the terms of
     the Indenture;

          (5)  that Holders electing to have a Note purchased pursuant to any
     Excess Proceeds Offer will be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Note
     completed, to the Company, a depositary, if appointed by the Company, or a
     Paying Agent at the address specified in the notice at least three Business
     Days before the Purchase Date;

          (6)  that Holders will be entitled to withdraw their election if the
     Company, depositary or Paying Agent, as the case may be, receives, not
     later than the expiration of the Offer Period, a facsimile transmission or
     letter setting forth the name of the Holder, the principal amount of the
     Note the Holder delivered for purchase and a statement that such Holder 
     is withdrawing his election to have the Note purchased;

          (7)  that, if the aggregate principal amount of Notes surrendered by
     Holders exceeds the Available Asset Sale Proceeds, the Trustee shall select
     the Notes to be purchased on a pro rata basis (with such adjustments as may
     be deemed appropriate by the Company so that only Notes in denominations of
     $l,000, or integral multiples thereof, shall be purchased) or by such other
     method as the Trustee shall deem fair and appropriate; and

          (8)  that Holders whose Notes were purchased only in part will be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered.

          On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis or by such other method as the
Trustee shall 

                                       52
<PAGE>
 
deem fair and appropriate to the extent necessary, Notes or portions thereof
tendered pursuant to the Excess Proceeds Offer, and deposit with the Paying
Agent U.S. legal tender sufficient to pay the purchase price plus accrued
interest, if any, on the Notes to be purchased and deliver to the Trustee an
Officers' Certificate stating that such Notes or portions thereof were accepted
for payment by the Company in accordance with the terms of this Section 4.10.
The Paying Agent shall promptly (but in any case not later than 5 days after the
Purchase Date) mail or deliver to each tendering Holder an amount equal to the
purchase price of the Note tendered by such Holder and accepted by the Company
for purchase, and the Company shall promptly issue a new Note, and the Trustee
shall authenticate and mail or make available for delivery such new Note to
such Holder equal in principal amount to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by
the Company to the Holder thereof. The Company will publicly announce the
results of the Excess Proceeds Offer on the Purchase Date; provided, however, 
                                                           --------  -------

extent required pursuant to the terms of Indebtedness outstanding as of the
Issue Date, offer to use such Available Asset Sale Proceeds to repurchase and
use all or a portion of such Available Asset Sale Proceeds to repurchase such
Indebtedness. If an Excess Proceeds Offer is not fully subscribed, the Company
may retain the portion of the Available Asset Sale Proceeds not required to
repurchase Notes for general corporate purposes.

Subsidiaries to, directly or indirectly, enter into any transaction or series
of related transactions (including, without limitation, the sale, purchase,
exchange or lease of assets, property or services) with any Affiliate
(including entities in which the Company or any of its Restricted Subsidiaries
own a minority interest) or holder of 10% or more of the Company's Common Stock
(an "Affiliate Transaction") or extend, renew, waive or otherwise modify the
terms of any Affiliate Transaction entered into prior to the Issue 

                                       53
<PAGE>
 
Date unless (i) such Affiliate Transaction is between or among the Company and
its Wholly-Owned Subsidiaries; (ii) such Affiliate Transaction is solely between
or among Wholly-Owned Subsidiaries of the Company; or (iii) the terms of such
Affiliate Transaction are fair and reasonable to the Company or such Restricted
Subsidiary, as the case may be, and the terms of such Affiliate Transaction are
at least as favorable as the terms which could be obtained by the Company or
such Restricted Subsidiary, as the case may be, in a comparable transaction made
on an arm's-length basis between unaffiliated parties; provided, however, that
                                                       --------  -------      
the Company and its Restricted Subsidiaries may renew any then existing
Affiliate Transaction through either a renewal option or upon expiration of an
arrangement on substantially similar terms to those in effect immediately
preceding such expiration.  In any Affiliate Transaction involving an amount or
having a value in excess of $1 million which is not permitted under clause (i)
or (ii) above, the Company must obtain a resolution of the Board of Directors
certifying that such Affiliate Transaction complies with clause (iii) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors.  In transactions with a value
in excess of $3 million which are not permitted under clause (i) or (ii) above,
the Company must obtain a written opinion as to the fairness from a financial
point of view of such a transaction from an independent investment banking firm
of national standing or real estate firm of national standing (as the case may
be).

          (b)  The limitations set forth in Section 4.11(a) will not apply to
(i) any Restricted Payment that is not prohibited by Section 4.9 hereof, (ii)
any trans action, approved by the Board of Directors of the Company in good
faith, with an officer, director, employee or consultant of the Company or of
any Subsidiary in his or her capacity as an officer, director, employee or
consultant entered into in the ordinary course of business, including
compensation, indemnity and employee benefit arrangements with any officer,
director, employee or consultant of the Company or of any Subsidiary, or (iii)
customary investment banking, underwriting, placement agent or financial advisor
fees paid in connection with services rendered to the Company or any Subsidiary.

debt of any Restricted Subsidiary which owns property or assets, now owned or
hereafter acquired, in any case which secures Indebtedness pari passu with or
                                                           ---- -----        
subordinated to the Notes unless (i) if such Lien secures Indebtedness which is
                                                                               
pari passu with the Notes, then the Notes are secured on an equal and ratable or
- ---- -----                                                                      
senior basis with the obligations so secured until such time as such obligation
is no longer secured by a Lien or (ii) if such Lien secures Indebtedness which
is subordinated to the Notes, any such Lien shall be subordinated to the Lien
granted to the Holders of the Notes in the same collateral to the same extent as
such subordinated Indebtedness is subordinated to the Notes.

Section 4.13.  Limitations on Investments.
               -------------------------- 

          The Company will not, and will not permit any of its Restricted

Restricted Subsidiary existing as of the date of this Indenture, (ii) a
Restricted Subsidiary that is acquired or created after the date of this

                                                --------  -------           
Restricted Subsidiary organized under the laws of the United States or any State

                                       55
<PAGE>
 
mentation relating thereto as the Trustee shall require, including, without
limitation, a supplement or amendment to this Indenture and an Opinion of
Counsel as to the enforceability of such Guarantee).

Section 4.15.  Limitation on Other Senior Subordinated Debt.
               -------------------------------------------- 

          The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, incur, contingently or otherwise, any
Indebtedness (other than the Notes and the Guarantees, as the case may be) that
is both (i) subordinate in right of payment to any Senior Indebtedness of the
Company or its Restricted Subsidiaries, as the case may be, and (ii) senior in
right of payment to the Notes and the Guarantees, as the case may be.  For
purposes of this Section 4.15, Indebtedness is deemed to be senior in right of
payment to the Notes and the Guarantees, as the case may be, if it is not
explicitly subordinate in right of payment to Senior Indebtedness at least to
the same extent as the Notes and the Guarantees, as the case may be, are
subordinate to Senior Indebtedness.

Section 4.16.  Limitation on Sale and Lease-Back Transactions.
               ---------------------------------------------- 

          The Company will not, and will not permit any Restricted Subsidiary

received in such Sale and Lease-Back Transaction is at least equal to the fair

the Company could incur the Attributable Indebtedness in respect of such Sale
and Lease-Back Transaction in compliance with Section 4.6.

indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder of any Notes for or as an inducement
to any consent, waiver or amendment of any of the terms or provisions of this
Indenture or the Notes unless such consideration is offered to be paid or agreed
to be paid to all Holders of the Notes which so consent, 

                                       56

required to preserve any such right, license or fran chise, or the corporate,
partnership or other existence of any of its Restricted Subsidiaries, if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and its Restricted
Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any
material respect to the Holders.

offer to purchase (the "Change of Control Offer") the outstanding Notes at a
purchase price equal to 101% of the principal amount thereof plus any accrued
and unpaid interest thereon to the Change of Control Payment Date (as

Trustee and to each Holder of the Notes, at the address appearing in the
register maintained by the Registrar of the Notes, a notice stating:

          (i)  that the Change of Control Offer is being made pursuant to this
     Section 4.19 and that all Notes tendered will be accepted for payment, and

          (iii)  that any Note not tendered will not be purchased and will
     continue to accrue interest;

          (iv)  that, unless the Company defaults in the payment of the Change
     of Control Purchase Price, any Notes accepted for payment pursuant to the
     Change of Control Offer shall cease to accrue interest after the Change of
     Control Payment Date;

                                       58
<PAGE>

     reverse of the Note completed, to the Paying Agent at the address specified
     in the notice prior to the close of business on the Business Day preceding
     the Change of Control Payment Date;

          (vi)  that Holders will be entitled to withdraw their acceptance if
     the Paying Agent receives, not later than the close of business on the
     third Business Day preceding the Change of Control Payment Date, a
     facsimile transmission or letter setting forth the name of the Holder, the
     principal amount of the Notes delivered for purchase, and a statement that
     such Holder is withdrawing his election to have such Notes purchased;

          (vii)  that Holders whose Notes are being purchased only in part will
     be issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered, provided that each Note purchased and each such new
                            --------                                           
     Note issued shall be in an original principal amount in denominations of

cepted and (2) cause to be credited to the respective accounts of the Holders
under a Global Note of beneficial interest so accepted payment in an amount

shall execute and issue, and the Trustee shall promptly authenticate and mail to
such holder, a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered and shall issue a Global Note equal in principal amount to
any unpurchased portion of benefi cial interest so surrendered; provided that
                                                                --------
each such new Note shall be issued in an original principal amount in
denominations of $1,000 and integral multiples thereof.

          (c) (i)  If the Company or any Subsidiary thereof has issued any
outstanding (A) Indebtedness that is subordinated in right of payment to the
Notes or (B) Preferred Stock, and the Company or such Subsidiary is required to
make a change of control offer or to make a distribution with respect to such
subordinated Indebtedness or Preferred Stock in the event of a Change of
Control, the Company shall not consummate any such offer or distribution with
respect to such subordinated Indebtedness or Preferred Stock until such time as
the Company shall have paid the Change of Control Purchase Price in full to the
holders of Notes that have accepted the Company's Change of Control Offer and
shall otherwise have consummated the Change of Control Offer made to holders of
the Notes and (ii) the Company will not issue Indebtedness that is subordinated
in right of payment to the Notes or Preferred Stock with change of control
provisions requiring the payment of such Indebtedness or Preferred Stock prior
to the payment of the Notes in the event of a Change of Control under this
Indenture.

          In the event that a Change of Control occurs and the Holders of Notes
exercise their right to require the Company to purchase Notes, if such purchase
constitutes a "tender offer" for purposes of Rule 14e-1 under the Exchange Act
at that time, the Company will comply with the requirements of Rule 14e-1 as
then in effect with respect to such repurchase.

or upon the Company in respect of the Notes and this Indenture may be served.
The Company shall give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the address of the Trustee as set
forth in Section 13.2.

          The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations.  The
Company shall give prompt written notice to the Trustee of such designation or
rescission and of any change in the location of any such other office or agency.

          The Company hereby initially designates the Corporate Trust Office of
the Trustee set forth in Section 13.2 as such office of the Company.

faith judgment of the Officers of the Company and shall cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in its judgment may be necessary, so that the business carried on in
connection therewith may be properly and advantageously conducted at all times
unless the failure to so maintain such properties (together with all other such
failures) would not have a material adverse effect on the financial condition or
results of operations of the Company and its Subsidiaries, taken as a whole;
provided, however, that nothing in this Section 4.21 shall prevent the Company
- --------  -------

properties, or disposing of any of them, if such discontinuance or disposal is
in the good faith judgment of the Board of Directors of the Company or the
Subsidiary concerned, as the case may be, desirable in the conduct of the
business of the Company or such Subsidiary, as the case may be, and is not
adverse in any material respect to the Holders.

          (b)  The Company shall provide or cause to be provided, for itself and
each of its Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds that, in the reasonable, good faith opinion
of the Company are adequate and appropriate for the conduct of the business of
the Company and such Subsidiaries in a prudent manner, with reputable insurers
or with the government of the United States of America or an agency or
instrumentality thereof, in such amounts, with such deductibles, and by such
methods as shall be customary, in the good faith judgment of the Company, for
corporations similarly situated in the industry, unless the failure to provide
such insurance (together with all other such failures) would not have a material
adverse effect on the financial condition or results of operations of the
Company and its Subsidiaries, taken as a

          (4)  there is a default in the payment at final maturity of principal
     in an aggregate amount of $3,000,000 or more with respect to any
     Indebtedness of the Company or any Restricted Subsidiary thereof which
     default shall not be cured, waived or postponed pursuant to an agreement
     with the holders of such Indebtedness within 60 days after written notice,
     or the acceleration of any such Indebtedness aggregating $3,000,000 or more
     which acceleration shall not be rescinded or annulled within 20 days after
     written notice to the Company of such Default by the Trustee or to the
     Company and the Trustee by any Holder;

          (5)  a court of competent jurisdiction enters a final judgment or
     judgments which can no longer be appealed for the payment of money in
     excess of $3,000,000 (which are not paid or covered by third party

          Subsidiary,

          and, in each case, the order or decree remains unstayed and in effect

Law.

          Subject to the provisions of Sections 7.1 and 7.2, the Trustee shall

Section 6.2.   Acceleration.
               ------------ 

          If an Event of Default (other than an Event of Default arising under
Section 6.1(6) or (7) with respect to the Company) occurs and is continuing, the
Trustee by notice to the Company, or the Holders of not less than 25% in
aggregate principal amount of the Notes then outstanding by written notice to
the Company and the Trustee, may declare to be immediately due and payable the
entire principal amount of all the Notes then outstanding plus premium, if any,
and accrued but unpaid interest to the date of acceleration and (i) such amounts
shall become immediately due and payable or (ii) if there are any amounts
outstanding under or in respect of the Credit Facility, such amounts shall
become due and payable upon the first to occur of an acceleration of amounts
outstanding under or in respect of the Credit Facility or five Business Days
after receipt by the Company and the Representative of notice of the
acceleration of the Notes; provided, however, that after such acceleration but
                           --------  -------
before a judgment or decree based on such acceleration is obtained by the
Trustee, the Holders of a majority in aggregate principal amount of the
outstanding Notes may rescind and annul such acceleration and its consequences
if all existing Events of Default, other than the nonpayment of accelerated
principal, premium, if any, or interest that has become due solely because of
the acceleration, have been cured or waived and if the rescission would not
conflict with any judgment or decree. No such rescission shall affect any
subsequent Default or impair any right consequent there to. In case an Event of
Default specified in Section 6.1 (6) or (7) with respect to the Company occurs,
the principal, premium, if any, and interest amount with respect to all of the
Notes shall be due and payable immediately without any declaration or other act
on the part of the Trustee or the Holders of the Notes.

Section 6.3.   Other Remedies.
               -------------- 

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of, or premium, if any, and interest on the Notes or to
enforce the performance of any provision of 

                                       67
<PAGE>
 
the Notes or this Indenture and may take any necessary action requested of it as
Trustee to settle, compromise, adjust or otherwise conclude any proceedings to
which it is a party.

          The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Noteholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative to the
extent permitted by law.

Section 6.4.   Waiver of Past Defaults and
               Events of Default.
               ---------------------------

          Subject to Sections 6.2, 6.7 and 8.2 hereof, the Holders of a majority
in principal amount of the Notes then outstanding have the right to waive any
existing Default or Event of Default or compliance with any provision of this
Indenture or the Notes.  Upon any such waiver, such Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
cured for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereto.

Section 6.5.   Control by Majority.
               ------------------- 

          The Holders of a majority in principal amount of the Notes then
outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee by this Indenture.  The Trustee, however, may refuse to
follow any direction that conflicts with law or this Indenture or that the
Trustee determines may be unduly prejudicial to the rights of another Noteholder
not taking part in such direction, and the Trustee shall have the right to
decline to follow any such direction if the Trustee, being advised by counsel,
determines that the action so directed may not lawfully be taken or if the
Trustee in good faith shall, by a Trust Officer, determine that the proceedings
so directed may involve it in personal liability; provided that the 
                                                  --------                     

                                       68
<PAGE>
 
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

Section 6.6.   Limitation on Suits.
               ------------------- 

          Subject to Section 6.7 below, a Noteholder may not institute any
proceeding or pursue any remedy with respect to this Indenture or the Notes
unless:

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

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

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

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

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60 day period by the Holders of a majority
     in aggregate principal amount of the Notes then outstanding.

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

Section 6.7.   Rights of Holders to Receive Payment.
               ------------------------------------ 

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal of, or premium, if any, and
interest of the Note on or after the respective due dates expressed in the
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates, is absolute and unconditional and shall not be impaired or

                                       69
<PAGE>
 
affected without the consent of the Holder.

Section 6.8.   Collection Suit by Trustee.
               -------------------------- 

          If an Event of Default in payment of principal, premium or interest
specified in Section 6.1(1) or (2) hereof occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against
the Company or the Guarantors (or any other obligor on the Notes) for the whole
amount of unpaid principal and accrued interest remaining unpaid, together with
interest on overdue principal and, to the extent that payment of such interest
is lawful, interest on overdue installments of interest, in each case at the
rate then borne by the Notes, and such further amounts as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, including all sums due and owing to the Trustee pursuant to Section
7.7.

Section 6.9.   Trustee May File Proofs of Claim.
               -------------------------------- 

          The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Noteholders allowed in any judicial proceedings relative to the Company or the
Guarantors (or any other obligor upon the Notes), its creditors or its property
and shall be entitled and empowered to collect and receive any monies or other
property payable or deliverable on any such claims and to distribute the same
after deduction of its reasonable charges and expenses to the extent that any
such charges and expenses are not paid out of the estate in any such proceedings
and any custodian in any such judicial proceeding is hereby authorized by each
Noteholder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the
Noteholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.7 hereof.

                                       70
<PAGE>
 
          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
or reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Noteholder in any such proceedings.

Section 6.10.  Priorities.
               ---------- 

          If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

     FIRST:  to the Trustee for amounts due under Section 7.7 hereof;

     SECOND:  to Noteholders for amounts due and unpaid on the Notes for
principal, premium, if any, and interest as to each, ratably, without preference
or priority of any kind, according to the amounts due and payable on the Notes;
and

     THIRD:  to the Company or, to the extent the Trustee collects any amount
from any Guarantor, to such Guarantor.

          The Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this Section 6.10.  The Trustee shall give the Company
prior notice of any such record date and payment date; provided, however, that
                                                       ---------  -------      
the failure to give any such notice shall not affect the establishment of such
record date or payment date or any payment to Noteholders pursuant to this
Section 6.10.

Section 6.11.  Undertaking for Costs.
               --------------------- 

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' 

                                       71
<PAGE>
 
fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder
pursuant to Section 6.7 hereof or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

Section 6.12.  Restoration of Rights and Remedies.
               ---------------------------------- 

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.


                                  ARTICLE 7.

                                    TRUSTEE

Section 7.1.   Duties of Trustee.
               ----------------- 

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

          (b)  Except during the continuance of an Event of Default:

          (1)  The Trustee need perform only those duties that are specifically
     set forth in this Indenture and no others and no implied covenants or
     obligations shall be read into this Indenture against the Trustee.

          (2)  In the absence of bad faith on its part, 

                                       72
<PAGE>
 
     the Trustee may conclusively rely, as to the truth of the statements and
     the correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture but, in the case of any such certificates or opinions which
     by any provision hereof are specifically required to be furnished to the
     Trustee, the Trustee shall be under a duty to examine the same to determine
     whether or not they conform to the requirements of this Indenture (but
     need not confirm or investigate the accuracy of mathematical calculations
     or other facts stated therein).

          (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

          (1)  This paragraph does not limit the effect of paragraph (b) of this
     Section 7.1.

          (2)  The Trustee shall not be liable for any error of judgment made in
     good faith by a Trust Officer, unless it is proved that the Trustee was 
     negligent in ascertaining the pertinent facts.

          (3)  The Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Sections 6.2 and 6.5 hereof.

          (4)  No provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its rights or powers if it shall have reasonable
     grounds for believing that repayment of such funds or adequate indemnity
     satisfactory to it against such risk or liability is not reasonably
     assured to it.

          (d)  Whether or not therein expressly so provided, paragraphs (a),
(b), (c), (e) and (f) of this Section 7.1 shall govern every provision of this
Indenture that in any way relates to the Trustee.

                                       73
<PAGE>
 
          (e)  The Trustee may refuse to perform any duty or exercise any right
or power unless it receives indemnity reasonably satisfactory to it against any
loss, liability, expense or fee.

          (f)  The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company or
any Guarantor.  Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by the law.

Section 7.2.   Rights of Trustee.
               ----------------- 

          Subject to Section 7.1 hereof:

          (1)  The Trustee may rely on and shall be protected in acting or
     refraining from acting upon any document reasonably believed by it to be
     genuine and to have been signed or presented by the proper person.  The
     Trustee need not investigate any fact or matter stated in the document.

          (2)  Before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, or both, which shall
     conform to the provisions of Section 13.5 hereof. The Trustee shall be
     protected and shall not be liable for any action it takes or omits to take
     in good faith in reliance on such certificate or opinion.

          (3)  The Trustee may act through agents and attorneys and shall not be
     responsible for the misconduct or negligence of any agent or attorney
     (other than the negligence or willful misconduct of an agent who is an
     employee of the Trustee) appointed by it with due care.

          (4)  The Trustee shall not be liable for any action it takes or omits
     to take in good faith which it reasonably believes to be authorized or
     within its rights or powers; provided that the Trustee's conduct does not
                                  --------                                    
     constitute negligence or bad faith.

          (5)  The Trustee may consult with counsel of its selection, and the
     advice or opinion of such 

                                       74
<PAGE>
 
     counsel as to matters of law shall be full and complete authorization and 
     protection from liability in respect of any action taken, omitted or
     suffered by it hereunder in good faith and in accordance with the advice or
     opinion of such counsel.

Section 7.3.   Individual Rights of Trustee.
               ---------------------------- 

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may make loans to, accept deposits from, perform
services for or otherwise deal with the Company or any Guarantor, or any
Affiliates thereof, with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights.  The Trustee, however, shall be
subject to Sections 7.10 and 7.11 hereof.

Section 7.4.   Trustee's Disclaimer.
               -------------------- 

          The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Notes, it shall not be accountable for the Company's use
of the proceeds from the sale of Notes or any money paid to the Company pursuant
to the terms of this Indenture and it shall not be responsible for any statement
in the Notes or any document used in connection with the sale of the Notes other
than its certificate of authentication.

Section 7.5.   Notice of Defaults.
               ------------------ 

          If a Default occurs and is continuing and if it is actually known to
the Trustee, the Trustee shall mail to each Noteholder notice of the Default
within 90 days after it occurs.  Except in the case of a Default in payment of
the principal of, or premium, if any, or interest on any Note, the Trustee may
withhold the notice if and so long as the board of directors of the Trustee, the
executive committee or any trust committee of such board and/or its Trust
Officers in good faith determine(s) that withholding the notice is in the
interests of the Noteholders.

Section 7.6.   Reports by Trustee to Holders.
               ----------------------------- 

          If required by TIA (S) 313(a), within 60 days after March 1 of any
year, commencing March 1, 1998, the 

                                       75
<PAGE>
 
Trustee shall mail to each Noteholder a brief report dated as of such March 1
that complies with TIA (S) 313(a); provided that no such report need be
                                   --------
transmitted if no such events listed in TIA (S) 313(a) have occurred within 
such period. The Trustee also shall comply with TIA (S) 313(b)(2). The Trustee
shall also transmit by mail all reports as required by TIA (S) 313(c) and TIA
(S) 313(d).

          A copy of each report at the time of its mailing to Noteholders shall
be filed with the SEC and each stock exchange on which the Notes are listed.
The Company shall promptly notify the Trustee when the Notes are listed on any
stock exchange.

Section 7.7.   Compensation and Indemnity.
               -------------------------- 

          The Company and the Guarantors shall pay to the Trustee from time to
time such reasonable compensation as shall be agreed in writing between the
Company and the Trustee for its services hereunder (which compensation shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust).  The Company and the Guarantors shall reimburse the Trustee
upon request for all reasonable disbursements, expenses and advances incurred or
made by it in connection with its duties under this Indenture, including the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

          The Company and the Guarantors shall indemnify each of the Trustee and
any predecessor Trustee for, and hold it harmless against, any and all loss,
damage, claim, liability, reasonable expense (including but not limited to
reasonable attorneys' fees and expenses) or taxes (other than taxes based on the
income of the Trustee) incurred by it in connection with the acceptance or
performance of its duties under this Indenture including the reasonable costs
and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder
(including, without limitation, settlement costs).  The Trustee shall notify the
Company and the Guarantors in writing promptly of any claim asserted against the
Trustee for which it may seek indemnity.  However, the failure by the Trustee to
so notify the 

                                       76
<PAGE>
 
Company and the Guarantors shall not relieve the Company or the Guarantors of
their obligations hereunder.

          Notwithstanding the foregoing, the Company and the Guarantors need not
reimburse the Trustee for any expense or indemnify it against any loss or
liability incurred by the Trustee through its negligence or bad faith.  To
secure the payment obligations of the Company and the Guarantors in this Section
7.7, the Trustee shall have a lien prior to the Notes on all money or property
held or collected by the Trustee in its capacity as such, except such money or
property held in trust to pay principal of and interest on particular Notes.
The obligations of the Company and the Guarantors under this Section 7.7 to
compensate and indemnify the Trustee and each predecessor Trustee and to pay or
reimburse the Trustee and each predecessor Trustee for expenses, disbursements
and advances shall be joint and several liabilities of the Company and each of
the Guarantors and shall survive the satisfaction and discharge of this
Indenture, including the termination or rejection hereof in any bankruptcy
proceeding to the extent permitted by law.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(6) or (7) hereof occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

          For purposes of this Section 7.7, the term "Trustee" shall include any
trustee appointed pursuant to Article 9.

Section 7.8.   Replacement of Trustee.
               ---------------------- 

          The Trustee may resign by so notifying the Company and the Guarantors
in writing, such resignation to become effective upon the appointment of a
successor Trustee.  The Holders of a majority in principal amount of the
outstanding Notes may remove the Trustee by notifying the removed Trustee in
writing and may appoint a successor Trustee with the Company's written consent
which consent shall not be unreasonably withheld.  The Company may remove the
Trustee at its election if:

          (1)  the Trustee fails to comply with Section 7.10 

                                       77
<PAGE>

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 8.1.   Without Consent of Holders.
               -------------------------- 

          The Company and the Guarantors, if any, when authorized by a Board
Resolution of each of them, and the Trustee may modify, waive, amend, restate or
supplement this Indenture, the Pledge Agreement or the Notes without notice to
or consent of any Noteholder:

          (1)  to comply with Section 5.1 hereof;

          (2)  to provide for uncertificated Notes in addition to or in place of
     certificated Notes;

          (3)  to comply with any requirements of the SEC under the TIA;

          (4)  to cure any ambiguity, defect or inconsistency, or to make any 
     other change that does not materially and adversely affect the rights of 
     any Noteholder; or

          (5)  to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Notes.

          The Trustee is hereby authorized to join with the Company and the
Guarantors, if any, in the execution 

                                       80
<PAGE>
 
of any supplemental indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations which
may be therein contained, but the Trustee shall not be obligated to enter into
any such supplemental indenture which adversely affects its own rights, duties
or immunities under this Indenture.

Section 8.2.   With Consent of Holders.
               ----------------------- 

          The Company, the Guarantors, if any, and the Trustee may modify,
amend, waive or supplement this Indenture, the Pledge Agreement or the Notes
with the written consent of the Holders of not less than a majority in
aggregate principal amount of the outstanding Notes without notice to any
Noteholder.  The Holders of not less than a majority in aggregate principal
amount of the outstanding Notes may waive compliance in a particular instance by
the Company with any provision of this Indenture or the Notes without notice to
any Noteholder.  Subject to Section 8.4, without the consent of each Noteholder
affected, however, an amendment, supplement or waiver, including a waiver
pursuant to Section 6.4, may not:

          (1)  reduce the amount of Notes whose Holders must consent to an
     amendment, modification, supplement or waiver to this Indenture, the
     Pledge Agreement or the Notes;

          (2)  reduce the rate of or change the time for payment of interest on
     any Note;

          (3)  reduce the principal of or premium on or change the stated
     maturity of any Note

          (4)  make any Note payable in money other than that stated in the Note
     or change the place of payment from New York, New York;

          (5)  change the amount or time of any payment required by the Notes or
     reduce the premium payable upon any redemption of the Notes in accordance
     with Section 3.7 hereof, or change the time before which no such redemption
     may be made;

                                       81
<PAGE>
 
          (6)  waive a default in the payment of the principal of, or interest
     on, or redemption payment with respect to, any Note (including any
     obligation to make a Change of Control Offer or, after the Company's
     obligation to purchase Notes arises thereunder, an Excess Proceeds Offer
     or modify any of the provisions or definitions with respect to such
     offers);

          (7)  make any changes in Sections 6.4 or 6.7 hereof or this sentence
     of Section 8.2; or

          (8)  affect the ranking of the Notes in a manner adverse to the
     Holders.

          After a modification, amendment, supplement or waiver under this
Section 8.2 becomes effective, the Company shall mail to the Holders a notice
briefly describing the modification, amendment, supplement or waiver.  Any
failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such modification,
amendment, supplement or waiver.

          It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, modification,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

Section 8.3.   Compliance with Trust Indenture Act.
               ----------------------------------- 

          Every amendment to or supplement of this Indenture or the Notes shall
comply with the TIA as then in effect.

                                       82
<PAGE>
 
Section 8.4.   Revocation and Effect of Consents.
               --------------------------------- 

          Until a modification, amendment, supplement, waiver or other action
becomes effective, a consent to it by a Holder of a Note is a continuing consent
conclusive and binding upon such Holder and every subsequent Holder of the same
Note or portion thereof, and of any Note issued upon the transfer thereof or in
exchange therefor or in place thereof, even if notation of the consent is not
made on any such Note.  Any such Holder or subsequent Holder, however, may
revoke the consent as to his Note or portion of a Note, if the Trustee receives
the notice of revocation before the date the modification, amendment,
supplement, waiver or other action becomes effective.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any modification,
amendment, supplement, or waiver.  If a record date is fixed, then,
notwithstanding the preceding paragraph, those Persons who were Holders at such
record date (or their duly designated proxies), and only such Persons, shall be
entitled to consent to such modification, amendment, supplement, or waiver or to
revoke any consent previously given, whether or not such Persons continue to be
Holders after such record date.  No such consent shall be valid or effective for
more than 90 days after such record date unless the consent of the requisite
number of Holders has been obtained.

          After a modification, amendment, supplement, waiver or other action
becomes effective, it shall bind every Noteholder, unless it makes a change
described in any of clauses (1) through (8) of Section 8.2 hereof.  In that
case, the modification, amendment, supplement, waiver or other action shall bind
each Holder of a Note who has consented to it and every subsequent Holder of a
Note or portion of a Note that evidences the same debt as the consenting
Holder's Note.

Section 8.5.   Notation on or Exchange of Notes.
               -------------------------------- 

          If a modification, amendment, supplement or waiver changes the terms
of a Note, the Trustee may request the Holder of the Note to deliver it to the

                                       83
<PAGE>
 
Trustee.  In such case, the Trustee shall place an appropriate notation on the
Note about the changed terms and return it to the Holder. Alternatively, if the
Company or the Trustee so determines, the Company in exchange for the Note shall
issue and the Trustee shall authenticate and make available for delivery a new
security that reflects the changed terms. Failure to make the appropriate
notation or issue a new Note shall not affect the validity and effect of such
modification, amendment, supplement or waiver.

Section 8.6.   Trustee to Sign Amendments, etc.
               --------------------------------

          The Trustee shall sign any modification, amendment, supplement or
waiver authorized pursuant to this Article 8 if the modification, amendment,
supplement or waiver does not adversely affect the rights, duties, liabilities
or immunities of the Trustee.  If it does, the Trustee may, but need not, sign
it.  In signing or refusing to sign such modification, amendment, supplement or
waiver, the Trustee shall be entitled to receive and, subject to Section 7.1
hereof, shall be fully protected in relying upon an Officers' Certificate and an
Opinion of Counsel stating that such modification, amendment, supplement or
waiver is authorized or permitted by this Indenture and such supplemental
indenture constitutes the legal, valid and binding obligation of the Company and
the Guarantors enforceable against each of them in accordance with its terms
(subject to customary exceptions).  The Company or any Guarantor may not sign a
modification, amendment or supplement until the Board of Directors of the
Company or such Guarantor, as appropriate, approves it.


                                   ARTICLE 9.

the obligations referred to in the last paragraph of this Section 9.1, if 

                                       84
<PAGE>
 
there shall have been cancelled by the Trustee or delivered to the Trustee for

from its obligations with respect to the Notes and the Guarantors, if any,
discharged from their obligations under the Guarantees, if any, on the date the
conditions set forth in Section 9.4 below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, such Legal Defeasance means that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Notes and to have satisfied all its other obligations under such Notes
and this Indenture insofar as such Notes are concerned (and the Trustee, at the
expense of the Company, shall, subject to Section 9.6 hereof, execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of outstanding Notes to receive solely from the trust funds described in
Section 9.4 hereof and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, (B) the Company's obligations with respect to such Notes
under Sections 2.3, 2.4, 2.5, 2.6, 2.7, 2.8 and 4.20 hereof, (C) the rights,

                                       85
<PAGE>
 
7.7 hereof) and (D) this Article 9. Subject to compliance with this Article 9,
the Company may exercise its option under this Section 9.2 with respect to the
Notes notwithstanding the prior exercise of its option under Section 9.3 below
with respect to the Notes.

Section 9.3.   Covenant Defeasance.
               ------------------- 

          At the option of the Company, pursuant to a Board Resolution, the
Company and the Guarantors, if any, shall be released from their respective
obligations under Sections 4.2 through 4.19 hereof, inclusive, and clause (a)
(iii) of Section 5.1 hereof with respect to the outstanding Notes on and after
the date the conditions set forth in Section 9.4 hereof are satisfied
(hereinafter, "Covenant Defeasance") and the Notes shall thereafter be deemed to
not be outstanding for purposes of any direction, waiver, consent, declaration
or act of the Holders (and the consequences thereof) in connection with such
covenants but shall continue to be outstanding for all other purposes hereunder.
For this purpose, such Covenant Defeasance means that the Company and the
Guarantors, if any, may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section or portion thereof, whether directly or indirectly by reason of any
reference elsewhere herein to any such specified Section or portion thereof or
by reason of any reference in any such specified Section or portion thereof to
any other provision herein or in any other document, but the remainder of this
Indenture and the Notes shall be unaffected thereby.

independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by

reason of 

                                       89
<PAGE>
 
any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting
such application, the obligations of the Company and any Guarantor under this
Indenture, the Notes and the Guarantees, if any, shall be revived and reinstated
as though no deposit had occurred pursuant to this Article 9 until such time as
the Trustee or Paying Agent is permitted to apply all such money or U.S.
Government Obligations in accordance with Section 9.1 hereof; provided, however,
                                                              --------  -------

Section 9.8. Moneys Held in Trust.
             -------------------- 

          Any moneys deposited with the Trustee or any Paying Agent or then held
by the Company or any Guarantors in trust for the payment of the principal of,
or premium, if any, or interest on any Note that are not applied but remain
unclaimed by the Holder of such Note for two years after the date upon which the
principal of, or premium, if any, or interest on such Note shall have
respectively become due and payable shall be paid to the Company or, if
appropriate, the Guarantors, upon Company Request, or if such moneys are then
held by the Company or any Guarantors in trust, such moneys shall be released
from such trust; and all liability of the Trustee or such Paying Agent with
respect to such trust money shall thereupon cease; provided, however, that the

any such Paying Agent, before being required to make any such repayment, may, at
the expense of the Company and the Guarantors, if any, either mail to each

unclaimed and that, after a date specified therein, which shall not be less than

                              GUARANTEE OF NOTES

Section 10.1.  Guarantee.
               --------- 

          Subject to the provisions of this Article 10, each Guarantor, by
execution of the Guarantee, will jointly and severally unconditionally guarantee
to each Holder and to the Trustee, on behalf of the Holders, (i) the due and
punctual payment of the principal of, and premium, if any, and interest on each
Note, when and as the same shall become due and payable, whether at maturity,
by acceleration or otherwise, the due and punctual payment of interest on the
overdue principal of, and premium, if any, and interest on the Notes, to the
extent lawful, and the due and punctual performance of all other Obligations of
the Company to the Holders or the Trustee all in accordance with the terms of
such Note and this Indenture, and (ii) in the case of any extension of time of
payment or renewal of any Notes or any of such other Obligations, that the same
will be promptly paid in full when due or performed in accordance with the terms
of the extension or renewal, at stated maturity, by acceleration or otherwise.
Each Guarantor, by execution of the Guarantee, will agree that its obligations
thereunder and hereunder shall be absolute and unconditional, irrespective of,
and shall be unaffected by, any invalidity, irregularity or unenforceability of
any such Note or this Indenture, any failure to enforce the provisions of any
such Note or this Indenture, any waiver, modification or indulgence granted to
the Company with respect thereto by the Holder of such Note or the Trustee, or
any other circumstances which may otherwise constitute a legal or equitable
discharge of a surety or such Guarantor.

          Each Guarantor, by execution of the Guarantee, will waive diligence,
presentment, filing of claims with a court in the event of merger or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest or notice with respect to any such Note or the Indebtedness evidenced
thereby and all demands whatsoever, and will covenant that the Guarantee will
not be discharged as to any such Note except by 

                                       92
<PAGE>
 
payment in full of the principal thereof, premium if any, and interest thereon
and as provided in Section 9.1 hereof. Each Guarantor, by execution of the
Guarantee, will further agree that, as between such Guarantor, on the one
hand, and the Holders and the Trustee, on the other hand, (i) the maturity of
the Obligations guaranteed by the Guarantee may be accelerated as provided in
Article 6 hereof for the purposes of the Guarantee, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
Obligations guaranteed thereby, and (ii) in the event of any declaration of
acceleration of such Obligations as provided in Article 6 hereof, such
Obligations (whether or not due and payable) shall forthwith become due and
payable by each Guarantor for the purpose of the Guarantee. In addition,
without limiting the foregoing provisions, upon the effectiveness of an
acceleration under Article 6 hereof, the Trustee shall promptly make a demand
for payment on the Notes under the Guarantee provided for in this Article 10
and not discharged. Failure to make such demand shall not affect the validity or
enforceability of the Guarantee upon any Guarantor.

          A Guarantee shall not be valid or become obligatory for any purpose
with respect to a Note unless the certificate of authentication on such Note
shall have been signed by or on behalf of the Trustee.

Section 10.2.  Execution and Delivery of Guarantees.
               ------------------------------------ 

          A Guarantee shall be executed on behalf of a Guarantor by the manual
or facsimile signature of an Officer of such Guarantor.  A guarantee need not be
affixed to a Note, and the validity and enforceability of any Guarantee shall
not be affected by the fact that it is not so affixed.

          If an Officer of a Guarantor whose signature is on the Guarantee no
longer holds that office, such Guarantee shall be valid nevertheless.

Section 10.3.  Limitation of Guarantee.
               ----------------------- 

          The obligations of each Guarantor will be limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of 

                                       93
<PAGE>
 
such Guarantor (including, without limitation, any guarantees of Senior
Indebtedness) and after giving effect to any collections from or payments made
by or on behalf of any other Guarantor in respect of the obligations of such
other Guarantor under its Guarantee or pursuant to its contribution obligations
under this Indenture, result in the obligations of such Guarantor under the
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
Federal or state law. Each Guarantor that makes a payment or distribution under
a Guarantee shall be entitled to a contribution from each other Guarantor in a
pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor.

Section 10.4.  Release of Guarantor.
               -------------------- 

          A Guarantor shall be released from all of its obligations under its
Guarantee if:

          (i) the Guarantor has sold all or substantially all of its assets or
     the Company and its Restricted Subsidiaries have sold all of the Capital
     Stock of the Guarantor owned by them, in each case in a transaction in
     compliance with Sections 4.10 and 5.1 hereof to the extent applicable; or

          (ii)  the Guarantor merges with or into or consolidates with, or
     transfers all or substantially all of its assets to, the Company or another
     Guarantor in a transaction in compliance with Section 5.1 hereof;

and in each such case, the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with.

Section 10.5.  Guarantee Obligations Subordinated to Guarantor Senior
               Indebtedness.
               ------------ 

          Each Guarantor, by execution of the Guarantee, will covenant and
agree, and each Holder of Notes, by its acceptance thereof, likewise covenants
and agrees, that to the extent and in the manner hereinafter set forth in this
Article 10, the Indebtedness represented by the 

                                       94
<PAGE>
 
Guarantee and the payment of any Obligations pursuant to the Guarantee by such
Guarantor are hereby expressly made subordinate and subject in right of payment
as provided in this Article 10 to the prior indefeasible payment and
satisfaction in full in cash or, as acceptable to the holders of Guarantor
Senior Indebtedness of such Guarantor, in any other manner, of all existing and
future Guarantor Senior Indebtedness of such Guarantor.

          This Section 10.5 and the following Sections 10.6 through 10.11 shall
constitute a continuing offer to all Persons who, in reliance upon such
provisions, become holders of or continue to hold Guarantor Senior Indebtedness
of any Guarantor; and such provisions are made for the benefit of the holders of
Guarantor Senior Indebtedness of each Guarantor; and such holders are made
obligees hereunder and they or each of them may enforce such provisions.

any liquidation, dissolution or other winding-up of any Guarantor, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy

marshaling of assets or liabilities of any Guarantor, then and in any such
event:

          (1) the holders of all Guarantor Senior Indebtedness of such
     Guarantor shall be entitled to receive payment and satisfaction in full in
     cash or, as acceptable to the holders of such Guarantor Senior
     Indebtedness, in any other manner, of all amounts due on or in respect of
     all such Guarantor Senior Indebtedness, before the Holders of the Notes are
     entitled to receive or retain, pursuant to the Guarantee of such Guarantor,
     any payment or distribution of any kind or character by such Guarantor on
     account of any of its Obligations on its Guarantee; and

     kind or character, whether in cash, property or securities, by set-off or
     otherwise, to which the Holders or the Trustee would be entitled but for
     the subordination provisions of this Article 10 shall be paid by the
     liquidating trustee or agent or other Person making such payment or
     distribution, whether a trustee in bankruptcy, a receiver or liquidating
     trustee or otherwise, directly to the holders of Guarantor Senior Indebted
     ness of such Guarantor or their representative or representatives or to the
     trustee or trustees under any indenture under which any instruments
     evidencing any of such Guarantor Senior Indebtedness may have been issued,

     extent necessary to make payment in full in cash or, as acceptable to the
     holders of such Guarantor Senior Indebtedness of such Guarantor, in any
     other manner, of all such Guarantor Senior Indebtedness remaining unpaid,
     after giving effect to any concurrent payment or distribution to the
     holders of such Guarantor Senior Indebtedness; and

          (3) in the event that, notwithstanding the foregoing provisions of
     this Section 10.6, the Trustee or the Holder of any Note shall have
     received any payment or distribution of assets of such Guarantor of any
     kind or character, whether in cash, property or securities, including,
     without limitation, by way of set-off or otherwise, in respect of any of
     its Obligations on its Guarantee before all Guarantor Senior Indebtedness
     of such Guarantor is paid and satisfied in full in cash or such payment and
     satisfaction thereof in cash is provided for, then and in such event such
     payment or distribution upon written notice to the Trustee or the Holder of
     such Note, as the case may be, shall be held by the Trustee or the Holder
     of such Note, as the case may be, in trust for the benefit of the holders
     of such Guarantor or Senior Indebtedness and shall be immediately paid
     over or delivered forthwith to the liquidating trustee or agent or other
     Person making payment or distribution of assets of such Guarantor 

                                       96

with or into, another Person or the liquidation or dissolution of a Guarantor
following the transfer of all of its assets (as an entirety or substantially as
an entirety) to another Person upon the terms and conditions set forth in
Article 5 hereof shall not be deemed a dissolution, winding-up, liquidation,
reorganization, assignment for the benefit of creditors or marshaling of
assets and liabilities of such Guarantor for the purposes of this Article 10 if
the Person formed by such consolidation or the surviving entity of such merger
or the Person which acquires by transfer such assets (as an entirety or
substantially as an entirety) shall, as a part of such consolidation, merger or
transfer comply with the conditions set forth in such Article 5 hereof.

occurrence of a Payment Default, no payment or distribution of any assets or
securities of a Guarantor (or any Restricted Subsidiary or Subsidiary of such
Guarantor) of any kind or character (including, without limitation, cash,
property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other Indebtedness of such Guarantor being
subordinated to its Obligations on its Guarantee) may be made by or on behalf of
such Guarantor (or any Restricted Subsidiary or Subsidiary of such Guarantor),
including, without limitation, by way of set-off or otherwise, for or on account
of its Obligations on its Guarantee, and neither the Trustee nor any holder or
owner of any Notes shall take or receive from any Guarantor (or any Restricted

manner, payment

                                       97
<PAGE>
 
in respect of all or any portion of its Obligations on its Guarantee following
the delivery by the representative of the holders of Guarantor Senior
Indebtedness (the "Guarantor Representative") to the Trustee of written notice
of (i) the occurrence of a Payment Default on Designated Senior Indebtedness
which constitutes Guaran tor Senior Indebtedness or (ii) the occurrence of a 
Non-Payment Event of Default on Designated Senior Indebtedness which constitutes
Guarantor Senior Indebtedness and the acceleration of the maturity of such
Designated Senior Indebtedness in accordance with its terms, and in any such
event, such prohibition shall continue until such Payment Default is cured,
waived in writing or ceases to exist or such acceleration has been rescinded or
otherwise cured. At such time as the prohibition set forth in the preceding
sentence shall no longer be in effect, subject to the provisions of the
following paragraph (b), such Guarantor shall resume making any and all
required payments in respect of its Obligations under its Guarantee.

          (b) Unless Section 10.6 hereof shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness
which constitutes Guarantor Senior Indebtedness of any Guarantor, no payment or
distribution of any assets or securities of such Guarantor of any kind or
character (including, without limitation, cash, property and any payment or
distribution which may be payable or deliverable by reason of the payment of any
other Indebtedness of such Guarantor being subordinated to its Obligations on
its Guarantee) shall be made by such Guarantor, including, without limitation,
by way of set-off or otherwise, for or on account of any of its Obligations on

shall take or receive from any Guarantor (or any Restricted Subsidiary or

(a "Guarantee Payment Blockage Period") commencing on the date of receipt by the
Trustee of written notice from the Guarantor Representative of such Non-Payment
Event of Default, unless and until (subject to any blockage of payments that may
then be in effect under the preceding paragraph (a)) the earliest to occur of
the following events:  (x) more than 179 days shall 

                                       98

have elapsed since the date of receipt of such written notice by the Trustee,
(y) such Non-Payment Event of Default shall have been cured or waived in writing
or shall have ceased to exist or such Designated Senior Indebtedness shall have
been paid in full in cash and the Trustee has been so notified either by the
Guarantor Representative or such Guarantor or (z) such Guarantee Payment
Blockage Period shall have been terminated by written notice to such Guarantor
or the Trustee from the Guarantor Representative, after which, in the case of
clause (x), (y) or (z), such Guarantor shall resume making any and all required
payments in respect of its Obligations on its Guarantee, including any missed
payments. Notwithstanding any other provisions of this Indenture, no event of
default with respect to Designated Senior Indebtedness which constitutes
Guarantor Senior Indebtedness (other than a Payment Default) which existed or
was continuing on the date of the commencement of any Guarantee Payment Blockage
Period initiated by the Guarantor Representative shall be, or be made, the
basis for the commencement of a second Guarantee Payment Blockage Period
initiated by the Guarantor Representative unless such event of default shall
have been cured or waived for a period of not less than 90 consecutive days. In
no event shall a Guarantee Payment Blockage Period extend beyond 179 days from
the date of the receipt by the Trustee of the notice referred to in this Section
10.7(b) or, in the event of a Non-Payment Event of Default which formed the
basis for a Payment Blockage Period under Section 11.3(b) hereof, 179 days from
the date of the receipt by the Trustee of the notice referred to Section 11.3(b)
(the "Initial Guarantee Blockage Period"). Any number of additional Guarantee
Payment Blockage Periods may be commenced during the Initial Guarantee Blockage
Period; provided, however, that no such additional Guarantee Payment Blockage
        --------  -------
Period shall extend beyond the Initial Guarantee Blockage Period. After the
expiration of the Initial Guarantee Blockage Period, no Guarantee Payment
Blockage Period may be commenced under this Section 10.7(b) and no Payment
Blockage Period may be commenced under Section 11.3(b) hereof until at least 180
consecutive days have elapsed from the last day of the Initial Guarantee
Blockage Period.

          (c) In the event that, notwithstanding the foregoing, the Trustee or
the Holder of any Note shall 

                                       99
<PAGE>
 
have received any payment from a Guarantor prohibited by the foregoing
provisions of this Section 10.7, then and in such event such payment shall be
paid over and delivered forthwith to the Guarantor Representative initiating
the Guarantee Payment Blockage Period, in trust for distribution to the holders
of Guarantor Senior Indebtedness or, if no amounts are then due in respect of
Guarantor Senior Indebtedness, promptly returned to the Guarantor, or as a
court of competent jurisdiction shall direct.

Section 10.8.  Subrogation to Rights of Holders of Guarantor Senior 
               Indebtedness.
               ----------------------------------------------------

          Upon the payment in full of all amounts payable under or in respect of
all Guarantor Senior Indebtedness of a Guarantor, the Holders shall be
subrogated to the rights of the holders of such Guarantor Senior Indebtedness
to receive payments and distributions of cash, property and securities of such
Guarantor made on such Guarantor Senior Indebtedness until all amounts due to be
paid under the Guarantee shall be paid in full.  For the purposes of such
subrogation, no payments or distributions to holders of Guarantor Senior
Indebtedness of any cash, property or securities to which Holders of the Notes
or the Trustee would be entitled except for the provisions of this Article 10,
and no payments over pursuant to the provisions of this Article 10 to holders of
Guarantor Senior Indebtedness by Holders of the Notes or the Trustee, shall, as
among each Guarantor, its creditors other than holders of Guarantor Senior
Indebtedness and the Holders of the Notes, be deemed to be a payment or
distribution by such Guarantor to or on account of such Guarantor Senior
Indebtedness.

          If any payment or distribution to which the Holders would otherwise
have been entitled but for the provisions of this Article 10 shall have been
applied, pursuant to the provisions of this Article 10, to the payment of all
amounts payable under Guarantor Senior Indebtedness, then and in such case, the
Holders shall be entitled to receive from the holders of such Guarantor Senior
Indebtedness at the time outstanding any payments or distributions received by
such holders of Guarantor Senior Indebtedness in excess of the amount sufficient
to indefeasibly pay all amounts payable under or in respect 

                                      100

of such Guarantor Senior Indebtedness in full in cash.

Section 10.9.  Guarantee Subordination Provisions
               Solely to Define Relative Rights.
               ----------------------------------

          The subordination provisions of this Article 10 are and are intended
solely for the purpose of defining the relative rights of the Holders of the
Notes on the one hand and the holders of Guarantor Senior Indebtedness on the
other hand. Nothing contained in this Article 10 or elsewhere in this Indenture
or in the Notes is intended to or shall (a) impair, as among each Guarantor,
its creditors other than holders of its Guarantor Senior Indebtedness and the
Holders of the Notes, the obligation of such Guarantor, which is absolute and
unconditional, to make payments to the Holders in respect of its Obligations on
its Guarantee in accordance with its terms; or (b) affect the relative rights
against such Guarantor of the Holders of the Notes and creditors of such
Guarantor other than the holders of the Guarantor Senior Indebtedness; or (c)
prevent the Trustee or the Holder of any Note from exercising all remedies
otherwise permitted by applicable law upon a Default or an Event of Default
under this Indenture, subject to the rights, if any, under this Article 10 of
the holders of Guarantor Senior Indebtedness (1) in any insolvency or bankruptcy
case or proceeding, or any receivership, liquidation, arrangement,
reorganization or other similar case or proceeding in connection therewith or
any liquidation, dissolution or other winding-up, or any assignment for the
benefit of creditors or other marshaling of assets and liabilities referred to
in Section 10.6 hereof, to receive, pursuant to and in accordance with such
Section, cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder, or (2) under the conditions specified in Section 10.7
hereof, to prevent any payment prohibited by such Section or enforce their
rights pursuant to Section 10.7(c) hereof.

          The failure by any Guarantor to make a payment in respect of its
obligations on its Guarantee by reason of any provision of this Article 10 shall
not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

following the delivery by the representative of the holders of Designated Senior
Indebtedness (the "Representative") to the Trustee of written notice of (i) the
occurrence of a Payment Default on Designated Senior Indebtedness or (ii) the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness
and the acceleration of the maturity of Designated Senior Indebtedness in
accordance with its terms, and in any such event, such prohibition shall
continue until such Payment Default is cured, waived in writing or ceases to
exist or such acceleration has been rescinded or otherwise cured; provided that
                                                                  --------

any other provisions of this Indenture, no event of default with respect to
Designated Senior Indebtedness (other than a Payment Default) which existed or
was continuing on the date of the commencement of any Payment Blockage Period
initiated by the Representative shall be, or be made, the basis for the
commencement of a second Payment Blockage Period initiated by the Representative

less than 90 consecutive days. In no event shall a Payment Blockage Period
extend beyond 179 days from the date of the receipt by the Trustee of the notice

Payment Blockage Period, in trust for distribution to the holders of Senior
Indebtedness or, if no amounts are then due in respect of Senior Indebtedness,
promptly returned to the Company, or otherwise as a court of competent

undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article 11, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee.  The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and the Trustee shall
not be liable to any holder of Senior Indebtedness if it shall mistakenly pay
over or deliver to Holders, the Company or any other Person moneys or assets to
which any holder of Senior Indebtedness shall be entitled by virtue of this

the Notes shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of,
premium, if any, and interest on the Notes shall be paid in full. For purposes
of such subrogation, no payments or distributions to the holders of Senior
Indebtedness of any cash, property or securities to which the Holders of the
Notes or the Trustee would be entitled except for the provisions of this Article
11, and no payments pursuant to the provisions of this Article 11 to the
holders of Senior Indebtedness by Holders of the Notes or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Indebtedness and
the Holders of the Notes, be deemed to be a payment or distribution by the
Company to or on account of the Senior Indebtedness.

          If any payment or distribution to which the Holders would otherwise
have been entitled but for the provisions of this Article 11 shall have been
applied, pursuant to the provisions of this Article 11, to the payment of all
amounts payable under the Senior Indebtedness of the Company, then and in such
case the Holders shall be entitled to receive from the holders of such Senior
Indebtedness at the time outstanding any payments or distributions received by
such holders of such Senior Indebtedness in excess of the amount sufficient to
indefeasibly pay all amounts payable under or in respect of such Senior
Indebtedness in full in cash.

Section 11.6.  Provisions Solely to Define Relative Rights.
               -------------------------------------------

          The provisions of this Article 11 are and are intended solely for the
purpose of defining the relative rights of the Holders of the Notes on the one
hand and the holders of Senior Indebtedness on the other hand.  Nothing
contained in this Article or elsewhere in this Indenture or in the Notes is
intended to or shall (a) impair, as among the Company, its creditors other than

<PAGE>
 
holders of Senior Indebtedness and the Holders of the Notes, the obligation of
the Company, which is absolute and unconditional, to pay to the Holders of the
Notes the principal of, premium, if any, and interest on the Notes as and when
the same shall become due and payable in accordance with their terms, or (b)
affect the relative rights against the Company of the Holders of the Notes
and creditors of the Company other than the holders of Senior Indebtedness or
(c) prevent the Trustee or the Holder of any Note from exercising all remedies
otherwise permitted by applicable law upon a Default or an Event of Default
under this Indenture, subject to the rights, if any, under this Article 11 of
the holders of Senior Indebtedness (1) in any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, arrangement, reorganization or
other similar case or proceeding in connection therewith, or any liquidation,
dissolution or other winding-up, or any assignment for the benefit of creditors
or other marshaling of assets and liabilities referred to in Section 11.2
hereof, to receive, pursuant to and in accordance with such Section, cash,
property and securities otherwise payable or deliverable to the Trustee or such
Holder, or (2) under the conditions specified in Section 11.3, to prevent any
payment prohibited by such Section or enforce their rights pursuant to Section
11.3(c) hereof.

          The failure to make a payment on account of principal of, premium, if
any, or interest on the Notes by reason of any provision of this Article 11
shall not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

Section 11.7.  Trustee to Effectuate Subordination.
               ----------------------------------- 

          Each Holder of a Note by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article and appoints the
Trustee his attorney-in-fact for any and all such purposes, including, in the
event of any dissolution, winding-up, liquidation or reorganization of the
Company whether in bankruptcy, insolvency, receivership proceedings, or
otherwise, the timely filing of a claim for the unpaid balance of the
indebtedness of the Company owing to such Holder in the form required in such

                                      110
<PAGE>
 
proceedings and the causing of such claim to be approved. If the Trustee does
not file such a claim prior to 30 days before the expiration of the time to file
such a claim, the holders  of Senior Indebtedness, or any Representative, may
file such a claim on behalf of Holders of the Notes.

Section 11.8.  No Waiver of Subordination Provisions.
               ------------------------------------- 

          (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

          (b) Without limiting the generality of subsection (a) of this Section
11.8, the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the Notes,
without incurring responsibility to the Holders of the Notes and without
impairing or releasing the subordination provided in this Article 11 or the
obligations hereunder of the Holders of the Notes to the holders of Senior
Indebtedness, do any one or more of the following:  (1) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness or any instrument evidencing the same (or any agreement under which
Senior Indebtedness is outstanding; (2) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of Senior Indebtedness; and (4) exercise or refrain from exercising any
rights against the Company and any other Person; provided, however, that in no

event shall any such actions limit the right of the Holders of the Notes to take
any action to accelerate the maturity of the Notes pursuant to Article 6 hereof

taking of such action does not otherwise violate the terms of this Indenture.

this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts which would prohibit the making of any payment to or by the Trustee
in respect of the Notes, unless and until the Trustee shall have received
written notice thereof from the Company or a holder of Senior Indebtedness or
from any trustee, fiduciary or agent therefor; and, prior to the receipt of any
such written notice, the Trustee, subject to the provisions of this Section
11.9, shall be entitled in all respects to assume that no such facts exist.

          (b) Subject to the provisions of Section 7.1 hereof, the Trustee shall
be entitled to rely on the delivery to it of a written notice to the Trustee and
the Company by a Person representing itself to be a holder of Senior
Indebtedness (or a trustee, fiduciary or agent therefor) to establish that such
notice has been given by a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor); provided, however, that failure to give such

notice to the Company shall not affect in any way the ability of the Trustee to
rely on such notice.  In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 11, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 11, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

January 15 and July 15 of each year (each an "Interest Payment Date"),
commencing on January 15, 1998, at the rate of 9% per annum.  Interest will be
computed on the basis of a 360-day year of twelve 30-day months.  Interest on
the Notes will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the date of the original issuance of the

          The Company shall pay interest on overdue principal, and on overdue
premium, if any, and overdue interest, to the extent lawful, at the rate equal
to 1% per annum in excess of the rate borne by the Notes.

above (except defaulted interest) to the person who is the registered Holder of
this Note at the close of business on the January 1 or July 1 preceding the
Interest Payment Date (whether or not such day is a Business Day).  The Holder
must surrender this Note to a Paying Agent to collect principal payments.  The
Company will pay principal, premium, if any, and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts; provided, however, that the Company may pay principal, premium,
               --------  -------                                              
if any, and interest by check payable in such money.  It may mail an interest
check to the Holder's registered address.

without notice to the Holders of the Notes. Neither the Company nor any of its
Subsidiaries or Affiliates may act as Paying Agent but may act as registrar or
co-registrar.

IV.  INDENTURE; RESTRICTIVE COVENANTS.

          The Company issued this Note under an Indenture dated as of July 7,
1997 (the "Indenture") by and between the Company and the Trustee.  The terms of
this Note include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code (S)(S)
77aaa-77bbbb) as in effect on the date of the Indenture.  This Note is subject
to all such terms, and the Holder of this Note is referred to the Indenture and
said Trust Indenture Act for a statement of them.  All capitalized terms in
this Note, unless otherwise defined, have the meanings assigned to them by the
Indenture.

          The Notes are general unsecured obligations of the Company limited to

repurchase of, capital stock of the Company and its subsidiaries, certain other
restricted payments by the Company and it subsidiaries, certain transactions
with, and investments in, its affiliates, certain sale and lease-back
transactions and a provision regarding change-of-control transactions. The
restrictions are subject to a number of important qualifications and exceptions.

V.   SUBORDINATION.

          The Indebtedness represented by the Notes is, to the extent and in the
manner provided in the Indenture, subordinated in right of payment to the prior
indefeasible payment and satisfaction in full in cash of all existing and future
Senior Indebtedness as defined in the Indenture, and this Note is issued subject
to such provisions.  Each Holder of this Note, by accepting the same, (a) agrees
to and shall be bound by such provisions,


                                      A-5
<PAGE>
 
(b) authorizes and directs the Trustee, on behalf of such Holder, to take
such action as may be necessary or appropriate to effectuate the subordination
as provided in the Indenture and (c) appoints the Trustee attorney-in-fact of
such Holder for such purpose; provided, however, that the Indebtedness evidenced
                               --------  -------
by this Note shall cease to be so subordinate and subject in right of payment
upon any defeasance of this Note referred to in Paragraph XVII below.

VI.  OPTIONAL REDEMPTION.

          The Company, at its option, may redeem the Notes, in whole or in part,
at any time on or after July 15, 2002 at the redemption prices set forth in
Section 3.7 of the Indenture, together, in each case, with accrued and unpaid
interest to the redemption date.

          In addition, the Company, at its option, may redeem Notes out of the
Net Proceeds of one or more Public Equity Offerings at the redemption price, in
the amount and under the terms set forth in the Indenture.

VII. NOTICE OF REDEMPTION.

          Notice of redemption will be mailed via first class mail at least 30
days but not more than 60 days prior to the redemption date to each Holder of
Notes to be redeemed at its registered address as it shall appear on the
register of the Notes maintained by the Registrar.  On and after any Redemption
Date, interest will cease to accrue on the Notes or portions thereof called for
redemption unless the Company shall fail to redeem any such Note.

VIII.     OFFERS TO PURCHASE.

          The Indenture requires that certain proceeds from Asset Sales be used,
subject to further limitations contained therein, to make an offer to purchase
certain amounts of Notes in accordance with the procedures set forth in the

occurrence of a Change of Control in accordance with procedures set forth in the
Indenture.

          The Notes are in registered form without coupons in denominations of
$1,000 and integral multiples thereof.  A Holder may register the transfer or
exchange of Notes in accordance with the Indenture.  The Registrar may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture.  The Registrar need not register the transfer of or exchange any Note
selected for redemption for a period of 15 days before the day of mailing of the
notice of redemption of any such Notes to be redeemed or any Note after it is
called for redemption in whole or in part, except the unredeemed portion of any
Note being redeemed in part.

X.   PERSONS DEEMED OWNERS.

          The registered Holder of this Note may be treated as the owner of it
for all purposes.

XI.  UNCLAIMED MONEY.

          If money for the payment of principal, premium or interest on any Note
remains unclaimed for two years, the Trustee or Paying Agent will pay the money
back to the Company at its request.  After that, Holders entitled to money must
look only to the Company for payment as general creditors unless an "abandoned
property" law designates another person.

XII. AMENDMENT, SUPPLEMENT AND WAIVER.

          Subject to certain exceptions, the Indenture or the Notes may be
modified, amended or supplemented by the Company, the Guarantors, if any, and
the Trustee with the consent of the Holders of at least a majority in principal
amount of the Notes then outstanding and any existing default or compliance with
any provision may be waived in a particular instance with the consent of the
Holders of a majority in principal amount of the Notes then outstanding.
Without the consent of Holders, the Company, the Guarantors, if any, and the
Trustee may amend the 

                                      A-7
<PAGE>
 
Indenture or the Notes or supplement the Indenture for certain specified
purposes including providing for uncertificated Notes in addition to
certificated Notes, and curing any ambiguity, defect or inconsistency, or making
any other change that does not materially and adversely affect the rights of any
Holder.

XIII.     SUCCESSOR ENTITY.

          When a successor corporation assumes all the obligations of its
predecessor under the Notes and the Indenture and immediately before and
thereafter no Default exists and certain other conditions are satisfied, the
predecessor corporation will be released from those obligations.

XIV. DEFAULTS AND REMEDIES.

          Events of Default are set forth in the Indenture.  If an Event of
Default (other than an Event of Default pursuant to Section 6.1(6) or (7) of the
Indenture with respect to the Company) occurs and is continuing, the Trustee
by notice to the Company, or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding by written notice to the Company
and the Trustee, may declare to be immediately due and payable the entire
principal amount of all the Notes then outstanding plus accrued but unpaid
interest to the date of acceleration and (i) such amounts shall become
immediately due and payable or (ii) if there are any amounts outstanding under
or in respect of the Credit Facility, such amounts shall become due and payable
upon the first to occur of an acceleration of amounts outstanding under or in
respect of the Credit Facility or five Business Days after receipt by the
Company and the Representative of notice of the acceleration of the Notes;
provided, however, that after such acceleration but before judgment or decree
- -----------------
based on such acceleration is obtained by the Trustee, the Holders of a
majority in aggregate principal amount of the outstanding Notes may rescind and
annul such acceleration and its consequences if all existing Events of Default,
other than the nonpayment of principal, premium or interest that has become due
solely because of the acceleration, have been cured or waived and if the
rescission would not conflict with any judgment or decree. No such rescission
shall affect any
                                      A-8
<PAGE>
 
subsequent Default or impair any right consequent thereto.  In case
an Event of Default specified in Section 6.1(6) or (7) of the Indenture with
respect to the Company occurs, such, principal amount, together with premium,
if any, and interest with respect to all of the Notes, shall be due and payable
immediately without any declaration or other act on the part of the Trustee or
the Holders of the Notes.  The Trustee may withhold from Holders notice of any
continuing default (except a default in payment of principal, premium, if any,
or interest) if it determines that withholding notice is in their interests.

XV.  TRUSTEE DEALINGS WITH THE COMPANY.

          The Trustee under the Indenture, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the
Company, any Guarantor or their Affiliates, and may otherwise deal with the
Company, any Guarantor or their Affiliates, as if it were not Trustee.

XVI. NO RECOURSE AGAINST OTHERS.

          As more fully described in the Indenture, a director, officer,
employee, partner, affiliate, beneficiary or shareholder, as such, of the
Company or any Guarantor shall not have any liability for any obligations of
the Company or any Guarantor under the Notes or the Indenture or for any claim
based on, in respect or by reason of, such obligations or their creation.  The
Holder of this Note by accepting this Note waives and releases all such
liability.  The waiver and release are part of the consideration or the issuance
of this Note.

XVII.     DEFEASANCE AND COVENANT DEFEASANCE.

          The Indenture contains provisions for defeasance of the entire
indebtedness on this Note and for defeasance of certain covenants in the
Indenture upon compliance by the Company with certain conditions set forth in
the Indenture.
