                                     PART I

ITEM 1. BUSINESS

General

        MEDIQ Incorporated ("MEDIQ" or the "Company"), through its wholly-owned
subsidiary, MEDIQ/PRN Life Support Services, Inc. ("MEDIQ/PRN"), operates the
largest movable critical care and life support medical equipment rental business
in the United States. MEDIQ/PRN rents a wide variety of movable equipment for
use by acute care hospitals, alternative care facilities, nursing homes, and
home health care companies. MEDIQ/PRN constitutes the Company's principal
business, accounting for 98% and 97% of consolidated revenues from continuing
operations in 1996 and 1995, respectively. MEDIQ/PRN also participates in a
joint venture through a limited liability company. MEDIQ PRN/HNE, L.L.C., d/b/a
SpectraCair, which rents health care providers mattress systems designed to
treat, prevent or manage pressure ulcers. The Company's other operating
subsidiary, MEDIQ Management Services, Inc., is a provider of health care
management and consulting services to health care providers and management and
other administrative services to diagnostic imaging centers. During fiscal 1996,
the Company continued to pursue its previously announced strategy of divesting
substantially all operating assets other than MEDIQ/PRN and MEDIQ Management
Services and using the proceeds thereof to reduce indebtedness.

        In September 1996, the Company entered into an agreement with NutraMax
Products, Inc. ("NutraMax") pursuant to which NutraMax agreed to repurchase all
of its shares owned by the Company, for a purchase price of approximately $36.3
million, or $9.00 per share, and the Company sold its ownership interest in
HealthQuest, Inc. for $75,000 which approximated carrying value. In October
1996, PCI Services, Inc. ("PCI") was acquired by Cardinal Health, Inc.
("Cardinal"). In that transaction the Company received 1,449,000 shares
(adjusted for stock split) of Cardinal stock in exchange for its 46% ownership
interest in PCI. The Company anticipates selling its Cardinal shares during
fiscal 1997. In November 1996, the Company sold substantially all of the assets
of MEDIQ Mobile X-Ray Services, Inc. ("Mobile X-Ray") for $5.3 million in cash
and shares of Integrated Health Services ("IHS") common stock with a value of
$5.2 million with the possibility of the Company receiving additional cash
consideration based upon the occurrence of certain future events. These
transactions essentially complete the implementation of the Company's strategic
plan to dispose of its non-core assets.

        On October 1, 1996, the Company together with its wholly-owned
subsidiary, MEDIQ/PRN entered into a $260 million Credit Agreement with a group
of lenders. The facility comprises a $25 million working capital line of credit,
$135 million in term loans and a $100 million acquisition facility. Initial
drawings on the facility were used to prepay all of the Company's senior debt
(except capital leases) including MEDIQ/PRN's outstanding $100 million 12-1/8%
Senior Secured Notes due 1999, and MEDIQ/PRN's subordinated obligations. The new
facility may also be used, among other things, to finance the redemption or
repurchase of the Company's other publicly-traded debt, or to finance strategic
acquisitions.

        The Company also intends to expand its core businesses through strategic
acquisitions, which would be financed, at least in part, by drawings under its
new credit facility. However, there can be no assurance that any transactions
will occur, or if they occur that they will be successfully integrated with the
Company's existing operations.

        The Company was incorporated in 1977. Its principal offices are located
at One MEDIQ Plaza, Pennsauken, New Jersey.

MEDIQ/PRN Life Support Services, Inc.

        MEDIQ/PRN provides essential cost-effective services to its customers.
In order to maximize operating efficiency, health care providers often choose to
rent movable medical equipment rather than incur the capital costs required to
finance equipment purchases and the on-going expenses required for maintenance
and repair. In addition, renting patient-ready equipment provides a vital
adjunct that permits health care providers to meet periods of increased patient
census without the need for investing capital in stand-by equipment. MEDIQ/PRN
meets these needs by renting a wide variety of equipment to health care
providers across the continuum of care. As of September 30, 1996, MEDIQ/PRN had
available for rent over 650 different types of medical equipment, including
adult and infant ventilators, adult, infant, neonatal and fetal monitors,
infusion and suction pumps, incubators, infant warmers, pulse oximeters,
sequential compression devices, oxygen concentrators and other movable critical
care 

                                       2
<PAGE>

equipment for use in respiratory care, intensive care, labor and delivery,
pediatric, neonatal intensive care and other departments of acute care general
hospitals and for use in alternative care facilities, nursing homes, and by home
health care providers. MEDIQ/PRN's customers rent equipment, which is delivered
in most cases within two hours of a request, 24 hours a day, 365 days a year
through 74 branch offices in major cities nationwide and 11 independent
distributors. MEDIQ/PRN offers its customers a wide selection of rental programs
including (i) daily, weekly or monthly rentals with fixed rate terms, (ii)
longer-term rentals with pricing related to the length of the rental term, and
(iii) "usage" rentals on a per use, per hour or per day basis.

        MEDIQ/PRN also offers its Comprehensive Asset Management Program (CAMP),
which analyzes a customer's total critical care equipment activity from all
sources for the previous year. CAMP includes a menu of logistics and outsourcing
services for movable medical equipment assets including equipment, personnel,
maintance, documentation and tracking. MEDIQ/PRN also has programs where it
acquires all or part of the customer's equipment and rents the equipment back to
the customer, eliminating the customer's burdens of ownership, under utilization
and seasonal usage. MEDIQ/PRN's customers can benefit from the use of CAMP
through the reduction of biomedical and other hospital staff, lower equipment
maintenance expenses and the elimination or reduction of capital expenditures
for equipment. MEDIQ/PRN also offers its CAMP (Registered) Plus logistics
program that provides similar management services for multi-site health care
networks to manage, service and transport movable patient care equipment. A
proprietary bar-code based asset management system provides customers maximum
utilization of owned equipment. The system provides information used to track
equipment, capture lost patient charges, control inventory and equipment
migration, reduce the need for supplemental rentals and manage overall capital
planning.

        MEDIQ/PRN provides a logistics and distribution service to equipment
manufacturers to reduce their transportation costs through utilization of
MEDIQ/PRN's national branch office network.

        MEDIQ/PRN also distributes a variety of disposables, accessories, and
repair parts used with critical care equipment. MEDIQ/PRN provides one-stop
shopping for supplies from all the leading manufacturers, and is the exclusive
distributor of accessories and supplies for all the respiratory care equipment
manufactured by Siemens Medical Systems, Inc.

        MEDIQ/PRN also provides complete service, including
annual/major/electrical safety inspections, preventive maintenance and repairs
for most brands and models of critical care equipment through a nationwide team
of over 140 trained, experienced biomedical technicians. Service and repairs can
be performed on-site, or pick up and delivery is available for servicing at one
of MEDIQ/PRN's 85 locations or two major service centers.

        MEDIQ/PRN meets the needs of its customers for pre-owned equipment with
a complete remarketing program of every major equipment category. Health care
facilities can acquire pre-owned critical care equipment substantially below the
cost of purchasing new units.

        MEDIQ/PRN also offers its customers complete programs for ventilator
reconditioning including replacement of parts, calibration, operational
verification and cosmetics.

        No single customer accounted for more than 10% of MEDIQ/PRN's revenues
during fiscal 1996 or 1995.

Seasonality

        MEDIQ/PRN's business is seasonal, with demand historically peaking
during periods of increased hospital census, which generally occurs in the
winter months during the Company's second fiscal quarter.

                                       3
<PAGE>

Quality Assurance

        Quality control/quality assurance and risk management procedures are
conducted for all of MEDIQ/PRN's medical equipment by trained biomedical
technicians to ensure compliance with safety, testing and performance standards
at all branch offices. All equipment is serviced and tested prior to delivery to
customers in accordance with MEDIQ/PRN's Pre-Delivery Inspection Program, which
is primarily derived from the Emergency Care Research Institute's ("ECRI's")
programs. Most types of medical equipment rented by MEDIQ/PRN require routine
servicing at scheduled intervals based upon hours of usage or passage of time,
including complete testing and inspection of all components that may need to be
replaced or refurbished. Routine servicing is conducted by MEDIQ/PRN's trained
personnel at all of its branch locations. Major repairs are performed at
MEDIQ/PRN's Pennsauken, New Jersey or Santa Fe Springs, California maintenance
facilities by its biomedical equipment technicians.

Suppliers

        MEDIQ/PRN acquires substantially all of its medical equipment, repair
parts, accessories or disposable products from approximately 100 suppliers.
MEDIQ/PRN has entered into a long-term agreement with a vendor to purchase $7
million of certain products. MEDIQ/PRN is not dependent upon any single supplier
and believes that alternative purchasing sources of medical equipment are
available to MEDIQ/PRN should they be needed.

Competition

        The medical equipment rental industry is highly competitive, and
MEDIQ/PRN encounters competition in all regions in which it operates.
MEDIQ/PRN's competitors include (i) national and regional medical equipment
rental and leasing companies and medical equipment distributors which rent
medical equipment to health care providers; (ii) medical equipment manufacturers
which sell medical equipment directly to health care providers; and (iii)
general leasing and financing companies and financial institutions, such as
banks, which finance the acquisition of medical equipment by health care
providers. MEDIQ/PRN believes that key factors influencing the decision
regarding the selection of a medical equipment rental vendor include
availability and quality of medical equipment, service and price.

 Discontinued Operations

        In the fourth quarter of fiscal 1996, the Company entered into an
agreement with NutraMax (NASDAQ:NMPC), a leading private label health and
personal care products company. Pursuant to this agreement, the Company
anticipates selling to NutraMax all of the 4,037,258 shares of NutraMax common
stock owned by the Company at a price of $9.00 per share. Under the terms of the
agreement, the Company will receive from NutraMax $19.9 million in cash and an
interest-bearing promissory note in the amount of $16.4 million. The note is
payable when NutraMax shares owned by the Company, which currently are held in
escrow in support of the Company's 7.50% Exchangeable Subordinated Debentures,
are released from that escrow. The NutraMax shares are to be released from
escrow upon the purchase or redemption of the 7.50% debentures. Upon closing of
the transaction, the Company will realize an after-tax gain of $6.2 million. The
cash proceeds from this transaction will be used to reduce debt.

        On October 11, 1996, PCI, a leading provider of integrated
pharmaceutical packaging services, was acquired by Cardinal. As a result, the
Company received 966,000 shares of Cardinal stock which, based on the closing
price on October 11, 1996 had a market value of $79.2 million. The Company
recognized an after tax gain of $31.8 million in the first quarter of fiscal
1997. In December 1996, Cardinal's common stock split 3 for 2 and, accordingly,
the Company now owns 1,449,000 shares of Cardinal which have an aggregate market
value of $81.3 million based upon the closing price of $56.125 per share on
December 20, 1996. The Company anticipates selling its Cardinal shares in fiscal
1997 and using the proceeds to reduce debt.

                                       4
<PAGE>

        In the second quarter of fiscal 1995, the Company adopted a plan to sell
the following four non-core businesses: Medifac, Inc. ("Medifac"), a provider of
health care facility planning, architectural and development services; Health
Examinetics, Inc. ("Health Examinetics"), a provider of mobile health testing
services; MEDIQ Mobile X-Ray Services, Inc. ("Mobile X-Ray"), a provider of
portable X-ray and EKG services; and MEDIQ Imaging Services, Inc. ("MEDIQ
Imaging"), a provider of diagnostic imaging services in mobile and fixed sites.
In the fourth quarter of fiscal 1995, the Company revised the plan to include
the operations of HealthQuest, Inc. ("HealthQuest"), a provider of case
management and utilization review services. As a result, operating results and
net assets of these five businesses have been reported as discontinued
operations. Discontinued operations also include the Company's equity investment
in InnoServ Technologies, Inc. ("InnoServ") (NASDAQ:ISER) which, through its
various subsidiaries, provides hospitals, clinics and private physicians'
offices with maintenance services for diagnostic imaging equipment, shared
mobile computed tomography and cardiac catheterization services and other
radiological parts and supplies. The Company owns 2,030,000 shares of InnoServ
common stock, or approximately 40% of the outstanding shares. The present
business operations of InnoServ include the business of the Company's former
subsidiary, MEDIQ Equipment and Maintenance Services, Inc., which was merged
with InnoServ in 1994. The Company anticipates divesting its investment in
InnoServ in fiscal 1997. See footnote B to the Company's consolidated financial
statements for certain financial information about discontinued operations.

        In November 1996, the Company sold substantially all of the assets of
Mobile X-Ray to Symphony Diagnostics, Inc., a subsidiary of Integrated Health
Services, Inc. (NYSE:IHS) for $5.3 million in cash and shares of Integrated
Health Services common stock with a value of $5.2 million at the closing with
the possibility of the Company receiving additional cash consideration based
upon the occurrence of certain future events.

        In September 1996, the Company sold its ownership interest in
HealthQuest, Inc. for cash of $75,000 which approximated its carrying value.

        In August 1995, the Company sold the assets of MEDIQ Imaging to NMC
Diagnostic Services, Inc., a division of W. R. Grace and Co. for approximately
$17 million in cash and the assumption of $9.7 million of debt.

        In June 1995, the Company sold Medifac and certain related assets to the
management of Medifac for approximately $11 million in cash and notes, and the
assumption of $26.9 million of non-recourse debt.

        The Company expects to sell Health Examinetics to its management for
cash and an interest bearing note aggregating $1.7 million. The Company
presently anticipates that the sale transaction will be completed in
fiscal 1997.

Financial Information about Industry Segments

        The Company operates primarily in one business segment, exclusive of
discontinued operations. The Company, through MEDIQ/PRN, rents medical equipment
on a short-term basis nationwide. In fiscal 1996, this segment represented more
than 90% of the consolidated revenues, operating profits and assets exclusive of
corporate assets, which include net assets of discontinued operations of $54.7
million at September 30, 1996.

Government Regulations

        The Company's businesses are subject to Federal, state and local
regulations relating to the operation of such businesses. The Company is unable
to predict whether, or to what extent, new legislation or regulations affecting
its businesses will be enacted and, if enacted, what impact they will have on
the Company. In addition, government reimbursement of medical expenses are, to
an increasing extent, made at fixed rates unrelated to actual costs.
Consequently, hospitals and other health care 

                                       5
<PAGE>


providers are expected to continue to emphasize cost-containment and
cost-efficiency measures, which the Company believes will increase the demand
for its products and services. The following is a summary of some of the
significant regulations currently affecting the operations of MEDIQ/PRN and the
Company's other operations.

        Compliance with FDA Regulations - The FDA regulates companies which
manufacture, prepare, propagate, compound or process medical devices. Device
manufacturers must comply with registration and labeling regulations, submit
premarket notifications or obtain premarketing approvals, comply with medical
device reporting, tracking and post-market surveillance regulations and with
device good manufacturing practices ("GMPs"), and are subject to FDA inspection.
The GMP regulations specify the minimum standards for the manufacture, packing,
storage, and installation of medical devices, and impose certain record keeping
requirements. The FDA currently does not regulate MEDIQ/PRN or organizations
which provide similar services as MEDIQ/PRN as device manufacturers. However,
any company which services, repairs or reconditions medical devices could be
subject to regulatory action by the FDA if its activities cause the devices to
become adulterated or mislabeled. In addition, no assurance can be given that in
the future the FDA will not regulate as device manufacturers companies such as
MEDIQ/PRN, which acquire ownership of devices, recondition or rebuild such
devices and rent them to customers or which service, repair or recondition
devices owned by others. The Company is unable to predict the cost of compliance
if any such regulations were to be adopted. MEDIQ/PRN is required to comply with
certain other device tracking and reporting regulations administered by the FDA.

        See also "Legal Proceedings" herein for certain additional information.

Employees

        As of December 1, 1996, the Company and its wholly-owned subsidiaries
have approximately 800 employees, of which approximately 100 are employees of
discontinued operations. The Company believes relations with employees are
satisfactory.


ITEM 2. PROPERTIES

        The Company's principal facility is located in Pennsauken, New Jersey,
where the Company's corporate offices and a portion of its operating activities
are located, including MEDIQ/PRN's corporate offices. The Company and its
wholly-owned subsidiaries also lease office and warehouse space in approximately
80 locations throughout the United States for local and regional operations. The
properties owned and leased by the Company and its wholly-owned subsidiaries are
believed to be adequate for the Company's operations.

ITEM 3. LEGAL PROCEEDINGS

        MEDIQ Imaging, the assets of which were sold by the Company in August
1995, is presently the subject of a criminal and civil investigation by the
United States Attorney's Office for the District of New Jersey and the
Department of Health and Human Services. The investigation has focused on advice
given by certain MEDIQ Imaging employees to physician customers of MEDIQ Imaging
relating to the reassignment of certain Medicare claims. The Company and MEDIQ
Imaging voluntarily reported the issue to the U.S. Government in January 1995
after learning that the advice given by the employees may have been inconsistent
with the regulations relating to reassignment. The Company and MEDIQ Imaging
have been cooperating in the investigation. In August 1995, in connection with
the sale of MEDIQ Imaging, the Company provided the U.S. Government with a
guarantee of approximately $7.1 million in connection with any settlement or
judgment obtained by the U.S. Government. Management believes that there has
been no violation of any statute or regulation by MEDIQ Imaging or any of its
officers, directors or employees. Although the Company believes there has been
no violation, if the U.S. Government obtains a judgment, the amount of the
judgment against MEDIQ Imaging may exceed the guarantee amount. However,

                                       6
<PAGE>

management and outside counsel are not aware of any evidence that would enable
the U.S. Government to proceed against the Company beyond the limits of the
guarantee.

        MEDIQ Mobile X-Ray Services, Inc. ("Mobile X-Ray"), the assets of which
the Company sold in November 1996, is presently the subject of an investigation
by the Wage and Hour Division of the United States Department of Labor (the
"DOL"). The DOL has indicated that it believes that the practice of treating
technologists as exempt professionals is incorrect. The Company maintains that
the practice of treating x-ray technologists as exempt is correct and proper. A
request for an official position statement has been sent to the Wage and Hour
Administrator of the DOL. The DOL has indicated that it will broaden the scope
of the investigation to include technologists at all other Mobile X-Ray
locations. Potential liability is retroactive from the day a lawsuit is
initiated by the Solicitor of Labor and could include double liquidated damages
and penalties. No suit has been filed at this time.

        On November 28, 1995, in the United States District Court for the Middle
District of Pennsylvania, ATS Medical Servces, Inc. ("ATS"), a former subsidiary
of the Company, and the president of ATS each pled guilty to one count of
misprision of a felony in violation of Title 18, United States Code, Section 4.
In addition, ATS agreed to repay the government $2.1 million for excess
reimbursement received by ATS from the Medicare Program from 1988 through 1992.
The payment is part of a settlement agreement entered into between ATS, the
United States Government and Gerard Callie, a former ATS employee, who had filed
a civil lawsuit on behalf of the government against ATS pursuant to the False
Claim Act, Title 31, United States Code, Sections 3729 - et seq., relating to
ATS's alleged excess reimbursement. The court sentenced ATS, on June 24, 1996,
to a term of probation of two years. The court imposed no fine on ATS. A
mandatory special assessment of $200 was imposed and paid by ATS. In November
1996, in connection with the sale of Mobile X-Ray, the outstanding balance of
this obligation was paid with a portion of the proceeds of the sale.

        On June 12, 1996, the Company, ATS and Mobile X-Ray Services were sued
in the United States District Court for the Middle District of Pennsylvania by
Gerard and Sharon Callie, who are both former employees of ATS. The lawsuit
alleges that the Callies were wrongfully terminated and asserts claims pursuant
to the whistleblower provisions of the False Claims Act and the Pennsylvania
Wage Payment and Collection Law. The plaintiffs made a demand for damages
totaling nearly $800,000. The Company believes it has no liability and intends
to vigorously defend this case.

        In addition, the Company has pending several legal claims incurred in
the normal course of business, which in the opinion of management, will not have
material effect on the consolidated financial statements. See Note I to the
Company's Consolidated Financial Statements.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

        No matters were submitted to a vote of security holders during the
quarter ended September 30, 1996.


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


        For the purposes of calculating the aggregate market value of the shares
of common stock of the Company held by nonaffiliates, as shown on the cover page
of this report, it has been assumed that all the outstanding shares were held by
nonaffiliates except for the shares beneficially owned by directors and
executive officers of the Company. However, this should not be deemed to
constitute an admission that all directors and executive officers of the Company
are, in fact, affiliates of the Company, or that there are not other persons who
may be deemed to be affiliates of the Company. Further information concerning
shareholdings of officers, directors and principal shareholders is included in
the Company's definitive proxy statement filed or to be filed with the
Securities and Exchange Commission.

        As of December 1996, there were approximately 2,000 holders of record of
the Company's Common Stock and approximately 350 holders of record of the
Company's Preferred Stock. Since a portion of the Company's Common Stock and
Preferred Stock is held in "street" or nominee name, the Company is unable to
determine the exact number of beneficial holders.

        The Company did not pay any dividends in fiscal 1996 or 1995. The terms
of the Company's Credit Agreement, entered into on October 1, 1996, preclude the
payment of cash dividends until October 1, 1997.

Notes to Selected Consolidated Financial Data
(1)  The Company recorded a $6 million reserve on the note receivable from MHM
     Services, Inc. ("MHM") in 1996. Net gains (losses) from the sale of assets
     were $.6 million, ($.4) million, $4.7 million, ($.3) million and $3.0
     million in 1996, 1995, 1994, 1993 and 1992, respectively. In 1992, the
     Company recorded a loss reserve of $10.6 million for an investment in a
     real estate limited partnership.
(2)  On September 30, 1994, MEDIQ/PRN acquired the critical care and life
     support rental equipment inventory of KCI. The purchase price, which was
     primarily financed with long-term debt, approximated $88 million, including
     transaction costs and the assumption of certain capital lease obligations.

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

General

        During fiscal 1996 the Company continued to pursue its previously
announced strategy of divesting substantially all operating assets other than
MEDIQ/PRN and MEDIQ Management Services and using the proceeds thereof to reduce
indebtedness.

        In September 1996, the Company entered into an agreement with NutraMax
Products, Inc. ("NutraMax") pursuant to which NutraMax agreed to repurchase all
of its shares owned by the Company, for a purchase price of approximately $36.3
million, or $9.00 per share, and the Company sold its ownership interest in
HealthQuest, Inc. for $75,000 which approximated carrying value. In October
1996, PCI Services, Inc. ("PCI") was acquired by Cardinal Health, Inc.
("Cardinal"). In that transaction the Company received 1,449,000 shares
(adjusted for stock split) of Cardinal stock in exchange for its 46% ownership
interest in PCI. The Cardinal shares are anticipated to be sold during fiscal
1997. Accordingly, the Company's equity investments and equity in earnings of
PCI and NutraMax have been classified as discontinued operations in the
Company's consolidated financial statements. In November 1996, the Company sold
substantially all of the assets of MEDIQ Mobile X-Ray Services, Inc. ("Mobile
X-Ray") for $5.3 million in cash and shares of Integrated Health Services
("IHS") common stock with a value of $5.2 million with the possibility of the
Company receiving additional cash consideration based upon the occurrence of
certain future events. These transactions essentially complete the
implementation of the Company's strategic plan to dispose of its non-core
assets.

        With the $88 million acquisition in 1994 of the movable medical
equipment of KCI Therapeutic Services, Inc., a subsidiary of Kinetic Concepts,
Inc. ("KCI"), MEDIQ/PRN, the Company's core business, strengthened its position
as the leading company in the United States renting movable critical care to
acute care hospitals, alternative care facilities, nursing homes and health care
providers on an "as-needed basis." With the successful integration of these
assets into its 85 office distribution network, MEDIQ/PRN expanded its market
presence into all 50 states, increased market share and improved its service
standards.

        The Company intends to continue to seek to expand its core businesses
through other strategic acquisitions. However, there can be no assurances that
the Company will be successful in identifying suitable acquisition candidates,
consummating any transactions or, if it completes any acquisition transaction,
in successfully integrating the operations of any acquired entity.

        The Company's other operating subsidiary is MEDIQ Management Services,
Inc., a provider of management and consulting services to health care providers
and management and other administrative support services to diagnostic imaging
centers. MEDIQ/PRN also participates in a joint venture through a limited
liability company, MEDIQ PRN/HNE, L.L.C., d/b/a SpectraCair, which rents health
care providers mattress systems designed to treat, prevent or manage
pressure ulcers.

Discontinued Operations

        In the fourth quarter of fiscal 1996, the Company entered into an
agreement with NutraMax (NASDAQ:NMPC), a leading private label health and
personal care products company. Pursuant to this agreement the Company
anticipates selling to NutraMax all of the 4,037,258 shares of NutraMax common
stock owned by the Company at a price of $9.00 per share. Under the terms of the
agreement, the Company will receive from NutraMax $19.9 million in cash and an
interest-bearing promissory note in the amount of $16.4 million. The note is
payable when NutraMax shares owned by the Company, which currently are held in
escrow in support of the Company's 7.50% Exchangeable Subordinated Debentures,
are released from that escrow. The NutraMax shares are to be released from
escrow upon the purchase or redemption of the 7.50% debentures. Upon the closing
of the transaction, the Company will realize an after-tax gain of $6.2 million.
The cash proceeds from this transaction will be used to reduce debt.

                                       10
<PAGE>

        On October 11, 1996, PCI, a leading provider of integrated
pharmaceutical packaging services, was acquired by Cardinal. As a result, the
Company received 966,000 shares of Cardinal stock which, based on the closing
price on October 11, 1996 had a market value of $79.2 million. The Company
realized an after tax gain of $31.8 million in the first quarter of fiscal 1997.
In December 1996, Cardinal's common stock split 3 for 2 and the Company now owns
1,449,000 shares which have an aggregate market value of $81.3 million based
upon the closing price of $56.125 per share on December 20, 1996. The Company
anticipates selling its Cardinal shares in fiscal 1997 and using the proceeds to
reduce debt.

        In the second quarter of fiscal 1995, the Company adopted a plan to sell
the following four non-core businesses: Medifac, Inc. ("Medifac"), a provider of
health care facility planning, architectural and development services; Health
Examinetics, Inc. ("Health Examinetics"), a provider of mobile health testing
services; MEDIQ Mobile X-Ray Services, Inc. ("Mobile X-Ray"), a provider of
portable X-ray and EKG services; and MEDIQ Imaging Services, Inc. ("MEDIQ
Imaging"), a provider of diagnostic imaging services in mobile and fixed sites.
In the fourth quarter of fiscal 1995, the Company revised the plan to include
the operations of HealthQuest, Inc. ("HealthQuest"), a provider of case
management and utilization review services. As a result, operating results for
fiscal 1995 and net assets of these five businesses for fiscal 1995 and 1996
have been reported as discontinued operations. Discontinued operations also
include the Company's equity investment in InnoServ Technologies, Inc. which is
anticipated to be divested during fiscal 1997.

        In November 1996, the Company sold substantially all of the assets of
Mobile X-Ray to Symphony Diagnostics, Inc., a subsidiary of Integrated Health
Services, Inc. (NYSE:IHS) for $5.3 million in cash and shares of Integrated
Health Services common stock with a value of $5.2 million at the closing with
the possibility of the Company receiving additional cash consideration based
upon the occurrence of certain future events.

        In September 1996, the Company sold its ownership interest in
HealthQuest, Inc. for $.75,000 which approximated its carrying value.

        In August 1995, the Company sold the assets of MEDIQ Imaging to NMC
Diagnostic Services, Inc., a division of W.R. Grace & Co., for approximately $17
million in cash and the assumption of $9.7 million of debt.

        In June 1995, the Company sold Medifac and certain related assets to the
management of Medifac for approximately $11 million, consisting of $6 million in
cash and $5 million in notes, and the assumption of $26.9 million of
non-recourse debt.

        The Company expects to sell Health Examinetics to its management for
cash and an interest bearing note aggregating $1.7 million. The Company
presently anticipates that the sale transaction will be completed in fiscal
1997.

Results of Operations

Fiscal Year 1996 Compared with Fiscal Year 1995

        Revenues from continuing operations were $136.1 million, as compared to
$132.2 million in the prior year, an increase of $3.9 million, or 3%. Revenue
growth aggregating $6.2 million was primarily attributable to the sale of repair
parts, accessories and disposable products, outsourcing services and sales of
equipment. This growth was partially offset by lower equipment rentals as a
result of the absence in fiscal 1996 of a sustained flu season, the non-renewal
of a number of long-term rental

                                       11
<PAGE>

contracts as a result of customer purchases and a trend in the marketplace of
better utilization of equipment of customers partially offset by an increase in
the number or rental customers. The Company expects this trend to continue, with
increased potential for its CAMP and CAMP Plus programs as customers seek to
reduce capital and operating expenses.

        Operating income from continuing operations was $25.4 million, as
compared to $24.2 million in 1995, an increase of $1.2 million, or 5%. The
improvement in operating income was attributable to reductions in corporate
overhead of $4.1 million, as compared to fiscal 1995, as a result of
non-recurring expenses in fiscal 1995 associated with the activities of the
Special Committee of the Board of Directors and the reduction in corporate
personnel in connection with the corporate restructuring plan adopted in the
first quarter of fiscal 1996. This reduction was partially offset by a
restructuring charge of $2.2 million for employee severance costs incurred in
connection with a plan approved by the Board of Directors to downsize corporate
functions and consolidate certain activities with the operations of MEDIQ/PRN.

        Interest expense decreased 7%, to $27.3 million, from $29.2 million in
1995. The decrease was primarily attributable to a net reduction in indebtedness
and was partially offset by an increase in the interest rate of MEDIQ/PRN's $100
million Senior Secured Notes from 11-1/8% to 12-1/8% effective October 1, 1995.

        Interest income of $1.5 million was consistent with the prior year and
was primarily derived from the Company's note receivable from MHM Services,
Inc., ("MHM" formerly a wholly-owned subsidiary of the Company which was
spun-off to shareholders in August 1993).

        Other charges and credits for 1996 included the establishment of a
reserve on the note receivable from MHM of $6 million as a result of the
Company's analysis of the financial condition of MHM and a charge of $.6 million
related to the excess of the purchase price over the carrying value of a warrant
issued by MEDIQ/PRN in 1992 to a lender in connection with the financing of an
acquisition. The purchase price of the warrant was $1.6 million. These charges
were partially offset by gains on the sales of operating assets of $.6 million.
Fiscal 1995 included a loss of $1.1 million from the sale of the Company's
equity interest in New West Eyeworks, Inc. in April 1995 for $3.0 million, and
income of $.6 million representing a portion of the contingent proceeds earned
in 1995 from the prior year sale of the Company's interest in a kidney stone
treatment center.

        The pretax loss from continuing operations before extraordinary item was
$6.6 million for 1996, as compared to a pretax loss of $3.7 million in the prior
year. The increase in pretax loss was attributable to the reserve on the note
receivable from MHM, the restructuring charge and the charge related to the
repurchase of the MEDIQ/PRN warrant partially offset by net reductions in
interest expense and corporate overhead. The pretax loss in 1995 included
non-recurring expenses of $1.7 million related to the strategic activities of
the Board of Directors and a loss of $1.1 million on the sale of the Company's
equity interest in New West Eyeworks.

        The income tax benefit related to continuing operations was $.4 million,
as compared to a benefit of $.3 million in the prior year. The Company's
effective tax rates were disproportionate compared to the statutory rates as a
result of goodwill amortization and the non-recognition for state income tax
purposes of certain operating losses.

        Revenues from discontinued operations (excluding equity investors) were
$36.8 million in 1996, as compared to $78.4 million in 1995. The net loss from
discontinued operations was $10.7 million in 1996, as compared to $1.6 million
in 1995, and consisted principally of revisions to the estimates of sales
proceeds for the disposal of the Company's investments in discontinued
operations, including reserves relating to investigations as discussed in Item
3. "Legal Proceedings" and Note I to the Consolidated Financial Statements.

        In connection with repayments of debt, the Company realized an
extraordinary gain of $1.7 million, or $1.1 million net of taxes in 1996.

<PAGE>

Fiscal Year 1995 Compared with Fiscal Year 1994

        Revenues from continuing operations were $132.2 million, as compared to
$81.5 million in the prior year, an increase of $50.7 million, or 62%. This
revenue growth was primarily attributable to the KCI acquisition. The Company
incorporated the additional movable medical equipment obtained from the
acquisition on September 30, 1994 into its national distribution network with
the addition of six branch offices, which resulted in substantially higher
revenues.

        Operating income from continuing operations was $24.2 million, as
compared to $1.4 million in 1994. The improvement in operating income was
attributable to additional revenues and improved operating margins resulting
from the KCI acquisition. Non-operating activities, including corporate
overhead, accounted for operating losses of $7.8 million in 1995, as compared to
$6.1 million in 1994.

        Operating income from continuing operations in 1995 was adversely
affected by corporate general and administrative expenses of approximately $1.7
million incurred in connection with the Company's corporate strategic activities
during the year. These activities, which included the formation and activities
of a Special Committee of the Board of Directors to explore alternative ways of
maximizing shareholder value, were concluded in October 1995 when the Board
accepted the recommendation of the Special Committee to reject two outstanding
offers to acquire the Company and terminate any further efforts to sell the
Company at that time.

        Interest expense increased 37%, to $29.2 million, from $21.3 million in
1994. Increased debt associated with financing MEDIQ/PRN's acquisition of KCI on
September 30, 1994, resulted in higher interest expense, partially offset by
lower interest at the corporate level. Net cash proceeds from the sale of
discontinued operations in June and August 1995 aggregating approximately $24
million were used to reduce notes payable to banks and other long-term debt.

        Interest income was $1.5 million in 1995 and $1.4 million in 1994 and
was primarily derived from the Company's note receivable from MHM.

        Other charges and credits for 1995 included a loss of $1.1 million from
the sale of the Company's equity interest in New West Eyeworks, Inc. in April
1995 for $3.0 million, and income of $.6 million representing a portion of the
contingent proceeds earned in 1995 from the prior year sale of the Company's
interest in a kidney stone treatment center. Fiscal 1994 included a gain of $4.0
million related to the sale of the kidney stone treatment center and gains
totaling $1.4 million from dividends and the sale of other assets, including a
portion of the Company's equity interest in New West Eyeworks.

        The pretax loss was $3.7 million for 1995, as compared to a pretax loss
of $12.6 million in the prior year. The improvement in pretax income was
attributable to MEDIQ/PRN and the success of its integration of the assets
acquired in the KCI acquisition into its nationwide distribution network. Fiscal
1995 included non-recurring expenses of $1.7 million related to the strategic
activities of the Board of Directors and a loss of $1.1 million on the sale of
the Company's equity interest in New West Eyeworks. The pretax loss in 1994
included gains from the sale of the Company's interest in a kidney stone
treatment center and other assets totaling $5.4 million.

        The income tax benefit related to continuing operations was $.3 million,
as compared to $4.3 million in the prior year. The Company's effective tax rates
were disproportionate compared to the statutory rates as a result of goodwill
amortization and the non-recognition for state income tax purposes of certain
operating losses.

        Revenues from discontinued operations were $78.4 million in 1995, as
compared to $86.6 million in 1994. The net loss from discontinued operations was
$1.6 million in 1995, consisting of net income of $3.1 million from operations
partially offset by a net loss on disposal of $4.7 million  as compared to net
income of $1.0 million in the prior year.

Liquidity and Capital Resources

        In 1996, cash provided by operating activities increased to $29.1
million, as compared to $24.7 million in the prior year. This increase was
principally the result of increased operating income and reduced working capital
requirements.

        Net cash used in investing activities was $16.9 million for 1996,
primarily attributable to expenditures for rental medical equipment totaling
$18.1 million, the repurchase of the MEDIQ/PRN warrant for $1.6 million
partially offset by proceeds from the sale of assets and discontinued operations
of $5.5 million. The Company presently anticipates capital expenditures of
approximately $14 million during fiscal 1997, primarily for rental medical
equipment. The Company intends to finance the rental medical equipment
expenditures with cash from operations.

        Net cash used in financing activities was $11.9 million for 1996 and
consisted primarily of debt repayments of $39 million partially offset by
borrowings of $25.7 million and proceeds from exercise of stock options of $1.4
million.

        On October 1, 1996, the Company, together with MEDIQ/PRN entered into a
$260 million Credit Agreement with a group of lenders led by Banque Nationale de
Paris as Administrative Agent and Initial Issuing Bank and NationsBank, N.A. as
the Documentation Agent (the "Credit Agreement"). The Credit Agreement provides
for four separate loans, a Term A loan ($35 million), a Term B loan ($100
million), an Acquisition Revolver ($100 million) and a Working Capital Revolver
($25 million). The amounts available under the Credit Agreement allowed the
Company to refinance substantially all of its existing senior debt, its
outstanding lines of credit, all of MEDIQ/PRN's subordinated debt, and
MEDIQ/PRN's $100 million 12-1/8% Senior Secured Notes due 1999. Upon completion
of the financing, the Company had $40 million available under the Acquisition
Revolver and $10 million available under the Working Capital Revolver both of
which were available to the Company upon continued compliance with certain
financial covenants and/or ratios.

        The loans bear interest at either the prime rate plus a factor or at a
Eurodollar rate plus a factor. The factor changes quarterly based upon the
Company's leverage ratio. On October 1, 1996, the Company's interest rate on the
Term A loan, the Acquisition Revolver and the Working Capital Revolver was prime
(8.25% at September 30, 1996) plus 1.25% or Eurodollar (5.38 % at September 30,
1996) plus 2.75% and the interest rate on the Term B loan was prime plus 1.75%
or Eurodollar plus 3.25%. The loans are collateralized by substantially all of
the assets of the Company. The proceeds from the sales of PCI, NutraMax, Mobile
X-Ray and Health Examinetics aggregating approximately $128 million, must be
utilized to repay outstanding advances under the Acquisition Revolver upon
receipt.

        The Term A loan is payable in quarterly installments of $1.2 million
beginning December 31, 1996 through September 30, 2001 and in quarterly
installments of $2.75 million from December 31, 2001 through September 30, 2002.
The Term B loan is payable in quarterly installments of $.25 million beginning
December 31, 1996 through September 30, 2002, quarterly installments of $8.5
million in fiscal 2003 and quarterly installments of $15 million in fiscal 2004.
The Company can borrow and repay under the Acquisition Revolver until March 31,
1998 in accordance with the Credit Agreement. On March 31, 1998, the Acquisition
Revolver converts to a term loan which will be repaid in quarterly installments
beginning on June 30, 1998. The first two installments will be at 5.0% of the
converted

                                       14
<PAGE>

balance and all remaining quarterly payments will be at 5.625% of the converted
balance. The Working Capital Revolver terminates on September 30, 2002 at which
time all outstanding balances are due.

        The Credit Agreement requires the Company to maintain certain financial
ratios and imposes certain other financial and dividend limitations. The terms
of the Company's Credit Agreement preclude the payment of dividends until
October 1, 1997.

        As a result of the refinancing, the Company recognized in the first
quarter of 1997, an extraordinary charge of $13 million before taxes resulting
from the write-off of deferred charges and premiums incurred related principally
to the tender offer to purchase the $100 million Senior Secured Notes, and a
non-recurring charge of $11 million for the purchase of a warrant to purchase
10% of MEDIQ/PRN issued in connection with financing the KCI acquisition.

        Accordingly, the Company has reflected the outstanding balances of its
lines of credit, subordinated debt and Senior Secured Notes as long-term senior
debt on its Consolidated Balance Sheet at September 30, 1996.

        The Company may also use a portion of the new credit facility to redeem
or repurchase its 7.25% convertible subordinated debentures and its 7.50%
exchangeable subordinated debentures. However, except to the extent required by
the terms of the indentures pursuant to which these debentures were issued,
there can be no assurance that any such redemption or repurchase will occur.

        In accordance with the terms of the Credit Agreement, effective November
15, 1996, the Company entered into interest rate hedge transactions which
terminate in January 2000. Under one of these transactions, on $50 million of
borrowings, the Company's base Eurodollar borrowing rate is fixed at 6.26% per
annum, instead of a floating Eurodollar rate. Under the second hedge
transaction, on an additional $50 million of borrowings, the Company's base
Eurodollar rate cannot be lower than 5.25% or greater than 7.43%.

        The Company's 7.25% convertible subordinated debentures due 2006 require
the Company to offer to repurchase a portion of the debentures if stockholders'
equity is $40 million or less at the end of two consecutive fiscal quarters.
Since June 30, 1994, the Company's stockholders' equity has been less than $40
million. The Company repurchased $22.5 million principal amount of debentures in
fiscal 1996. As of September 30, 1996, the Company is required to either
repurchase or offer to redeer $11.25 million of debentures in fiscal 1997. These
debentures were reclassified to long-term senior debt in connection with the
terms of the refinancing discussed above since the redemption of the 7.25%
debentures must be made from drawings on the Acquisition Revolver. In November
and December 1996, the Company repurchased an aggregate of $2.2 million of the
debentures at approximately face value in the open market. The Company is
required to either repurchase or offer to redeem $9.05 million of debentures
prior to January 30, 1997 pursuant to the terms of the mandatory redemption
provisions of the indenture. Additionally, the Company is required to either
repurchase or offer to redeem $11.25 million of debentures prior to July 30,
1997 and semi-annually thereafter until all of the debentures are repurchased or
stockholders' equity is more than $40 million. Accordingly, the Company has
classified $22.5 million as senior debt in accordance with the terms of the
Credit Agreement.

        As of September 30, 1996, the Company had lines of credit aggregating
$31 million, bearing interest at rates ranging from prime (8.25% at September
30, 1996) to prime plus 1.5%. At September 30, 1996, the Company had $26.4
million in borrowings and $2.0 million of letters of credit outstanding under
these facilities. As a result of the refinancing discussed above, the
outstanding amounts under these facilities are reflected as long-term senior
debt in the Company's Consolidated Balance Sheet at September 30, 1996.

        The Company expects that its primary sources of liquidity for operating
activities will be generated through cash flows from MEDIQ/PRN. Proceeds from
the sale of discontinued operations and miscellaneous assets will be used to
repay long-term debt. The Company believes that sufficient funds will be
available from operating cash flows, the sale of assets and the new credit
facility to meet the Company's anticipated operating and capital requirements,
including obligations to redeem or repurchase in the open market a portion or
all of the 7.25% and/or 7.50% debentures as previously discussed.

                          Independent Auditors' Report


Board of Directors and Stockholders
MEDIQ Incorporated
Pennsauken, New Jersey


        We have audited the accompanying consolidated balance sheets of MEDIQ
Incorporated and subsidiaries as of September 30, 1996 and 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended September 30, 1996. Our audits also
include the financial statement schedules listed in the index at Item 14(a)(2).
These financial statements and financial statement schedules are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedules based on
our audits.

        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, such consolidated financial statements present fairly,
in all material respects, the financial position of MEDIQ Incorporated and
subsidiaries as of September 30, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 1996 in conformity with generally accepted accounting principles.
Also, in our opinion, such financial statement schedules, when considered in
relation to the basic consolidated financial statements taken as a whole,
present fairly in all material respects the information set forth therein.

Note A - Summary of Significant Accounting Policies

         Principles of consolidation - The consolidated financial statements
include the accounts of MEDIQ Incorporated and its subsidiaries (the "Company").
Investments in companies owned 20% to 50% are accounted for under the equity
method of accounting. All other investments are stated at the lower of cost or
net realizable value. In consolidation, all significant intercompany
transactions and balances have been eliminated.

         Inventories - Inventories, which consist primarily of repair parts for
rental equipment and finished goods held for sale, are stated at the lower of
cost (first-in, first-out method) or market.

         Property, plant and equipment - Rental equipment, machinery and
equipment, buildings and improvements, and land are recorded at cost. Capital
leases are recorded at the lower of fair market value or the present value of
future lease payments. The Company provides straight-line depreciation and
amortization over the estimated useful lives (rental equipment and machinery and
equipment - 3 to 10 years and buildings and improvements - 10 to 25 years).

         Goodwill - The cost of acquired businesses in excess of net assets is
amortized on a straight-line basis primarily over periods of 20 years.
Accumulated amortization was $15.3 million and $12 million as of September 30,
1996 and 1995, respectively.

         Carrying value of long-term assets - The Company evaluates the carrying
value of long-term assets, including rental equipment, goodwill and other
intangible assets, based upon current and anticipated undiscounted cash flows,
and recognizes an impairment when it is probable that such estimated cash flows
will be less than the carrying value of the asset. Measurement of the amount of
impairment, if any, is based upon the difference between carrying value and fair
value.

         Revenue recognition policy - Rental revenue is recognized in accordance
with the terms of the related rental agreement and the usage of the related
rental equipment. Revenues from other operating activities are recognized as
services are rendered or as income is earned.

         Subsidiary and unconsolidated affiliate stock transactions - Gains
(losses) resulting from the issuance or repurchase of stock by subsidiaries and
unconsolidated affiliates are recognized by the Company as equity participation
in the Consolidated Statements of Operations.

        Earnings (loss) per share - Primary net earnings (loss) per share are
computed by dividing net earnings (loss) by the weighted average number of
shares of common stock and common stock equivalents outstanding during the
period. Common stock equivalents include shares issuable upon conversion of the
Company's convertible preferred stock, convertible subordinated debt and
exercise of outstanding stock options.

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

         New Accounting Pronouncements - In October 1995, the Financial
Accounting Board issued Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation," ("SFAS 123"), which will be adopted
by the Company in fiscal year 1997 as required by the statement. The Company has
elected to continue to measure such compensation expense using the method
prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees,"as permitted by SFAS 123. When adopted, SFAS 123 will not
have a significant effect on the Company's financial position or results of
operations but will require the Company to provide expanded disclosure regarding
its stock-based employee compensation plans.

Note A - Summary of Significant Accounting Policies (Continued)

         Reclassification of accounts - Certain reclassifications have been made
to conform prior years' balances to the current year presentation.

Note B - Dispositions

        During fiscal 1996, the Company continued to pursue its previously
announced strategy of divesting substantially all operating assets other than
MEDIQ/PRN and Management Services, Inc. and using the proceeds thereof to reduce
indebtedness.

Discontinued Operations

        In the fourth quarter of fiscal 1996, the Company entered into an
agreement with NutraMax (NASDAQ:NMPC), a leading private label health and
personal care products company. Pursuant to this agreement, the Company
anticipates selling to NutraMax all of the 4,037,258 shares of NutraMax common
stock owned by the Company at a price of $9.00 per share. Under the terms of the
agreement, the Company will receive from NutraMax $19.9 million in cash and an
interest-bearing promissory note in the amount of $16.4 million. The note is
payable when NutraMax shares owned by the Company, which currently are held in
escrow in support of the Company's 7.50% Exchangeable Subordinated Debentures,
are released from that escrow. The NutraMax shares are to be released from
escrow upon the purchase or redemption of the 7.50% debentures. Upon closing of
the transaction, the Company will realize an after-tax gain of $6.2 million. The
cash proceeds from this transaction will be used to reduce debt.

        On October 11, 1996, PCI, a leading provider of integrated
pharmaceutical packaging services, was acquired by Cardinal. As a result, the
Company received 966,000 shares of Cardinal stock which, based on the closing
price on October 11, 1996 had a market value of $79.2 million. The Company
recognized an after tax gain of $31.8 million in the first quarter of fiscal
1997. In December 1996, Cardinal's common stock split 3 for 2 and, accordingly
the Company now owns 1,449,000 shares which have an aggregate market value of
$81.3 million based upon the closing price of $56.125 per share on December 20,
1996. The Company anticipates selling its Cardinal shares in fiscal 1997 and
using the proceeds to reduce debt.

         In the second quarter of fiscal 1995, the Company adopted a plan to
sell the following four non-core businesses: Medifac, Inc. ("Medifac"), a
provider of health care facility planning, architectural and development
services; Health Examinetics, Inc. ("Health Examinetics"), a provider of mobile
health testing services; MEDIQ Mobile X-Ray Services, Inc. ("Mobile X-Ray"), a
provider of portable X-ray and EKG services; and MEDIQ Imaging Services, Inc.
("MEDIQ Imaging"), a provider of diagnostic imaging services in mobile and fixed
sites. In the fourth quarter of fiscal 1995, the Company revised the plan to
include the operations of HealthQuest, Inc. ("HealthQuest"), a provider of case
management and utilization review services and the Company's equity investment
in InnoServ Technologies, Inc. which is anticipated to be divested during fiscal
1997.

         The Company's prior year consolidated financial statements have been
restated to report the net assets and operating results of these businesses and
equity investments as discontinued operations.

         In November 1996, the Company sold substantially all of the assets of
Mobile X-Ray to Symphony Diagnostics, Inc., a subsidiary of Integrated Health
Services, Inc. (NYSE:IHS) for $5.3 million in cash and shares of Integrated
Health Services common stock with a value of $5.2 million at the closing with
the possibility of the Company receiving additional cash consideration based
upon the occurrence of certain future events.

Note B - Dispositions (Continued)

        In September 1996, the Company sold its common stock investment in
HealthQuest, Inc. to management for approximately $75,000 which approximated its
carrying value.

         In August 1995, the Company sold the assets of MEDIQ Imaging Services,
Inc., the Company's mobile and fixed site ultrasound and nuclear imaging
business, to NMC Diagnostic Services Inc., a division of W.R. Grace & Co., for
approximately $17 million in cash, and the assumption of $9.7 million of debt.

         In June 1995, the Company sold Medifac, Inc., a health care facility
planning, design and project management firm, and related assets to the
management of Medifac for approximately $11 million, consisting of $6 million in
cash and $5 million in notes, and the assumption of $26.9 million of
non-recourse debt.

         In August 1994, the Company merged its MEDIQ Equipment and Maintenance
Services, Inc. ("MEMS") subsidiary with InnoServ, and the Company received
2,030,000 shares of InnoServ common stock, or approximately 40% of the
outstanding shares, and warrants to purchase at $6.25 per share an additional
325,000 shares of common stock. No gain or loss resulted from the merger. The
Company anticipates divesting its investment in InnoServ in fiscal 1997.

        The Company expects to sell Health Examinetics to its management for
cash and an interest bearing note aggregating $1.7 million. The Company
presently anticipates that the sale transaction will be completed in the second
quarter of fiscal 1997.

The investment in discontinued operations as of September 30, 1996 consisted of
(in thousands):

                                =======       =======

Revenues from discontinued operations (excluding equity investees) were $36.8
million, $78.4 million and $86.6 million in 1996, 1995 and 1994 respectively.

Sale of Other Assets

         In December 1993, the Company exercised warrants to purchase 229,518
shares of common stock of New West Eyeworks, Inc. ("New West") in connection
with New West's initial public offering. The warrants were issued to the Company
in 1988 together with $5.1 million of New West preferred stock as partial
consideration for the sale of a business. In connection with the offering, the
Company received $1.9 million, representing a partial redemption of the
preferred shares, net proceeds from the sale of 82,500 shares of common stock
and partial payment of accumulated preferred stock dividends and accrued
interest. The Company received an additional 57,143 shares of New West common
stock in payment of the balance of accumulated dividends and interest. The
Company recorded income of $1.2 million in 1994 related to the sale of New West
common stock and the payment of dividends and interest. In April 1995, the
Company sold its remaining investments in New West common stock and preferred
stock for aggregate consideration of $3 million resulting in a $1.1 million
pretax loss.

         In September 1994, the Company sold its rights under a management
contract related to a kidney stone treatment center for $4 million in cash and
$3 million contingent upon future results of operations. The sale resulted in a
pretax gain of $4 million in 1994 and $.6 million in 1995 representing a portion
of the contingent proceeds.

Note C - Restructuring Charge

         In the first quarter of fiscal 1996, the Company recorded a
restructuring charge of $2.2 million for employee severance costs incurred in
connection with a plan approved by the Board of Directors to downsize corporate
functions and consolidate certain activities with the operations of MEDIQ/PRN.
The plan resulted in the termination of 29 employees in fiscal 1996. The Company
paid approximately $.9 million of severance benefits in fiscal 1996 with the
balance of the restructuring obligation due over the next two fiscal years.


Note D - Acquisition

         On September 30, 1994, the Company acquired the critical care and life
support rental equipment inventory of KCI Therapeutic Services, Inc., a
subsidiary of Kinetic Concepts, Inc. ("KCI"). The purchase price was
approximately $88 million, including transaction costs and the assumption of
certain capitalized lease obligations. The purchase price was allocated to
assets acquired and liabilities assumed based on fair values at the date of the
acquisition. The excess of the purchase price over fair values of the net assets
acquired of $44.5 million was recorded as goodwill and is being amortized over
twenty years.

Note G - Notes Payable to Financial Institutions

As of September 30, 1996, the Company had $31 million of lines of credit which
bear interest at rates ranging from prime (8.25% at September 30, 1996) to prime
plus 1.5% and are secured primarily by a portion of the shares of common stock
of NutraMax and PCI owned by the company, certain accounts receivable, a pledge
of the common stock of MEDIQ/PRN and a second mortgage on real estate. At
September 30, 1996, $26.0 million in borrowings and $2.0 million of letters of
credit were outstanding under these facilities. The amount of available credit
fluctuated based upon the amount of eligible accounts receivable. The average
amount outstanding under lines of credit in 1996 was $17.7 million and the
weighted average interest rate computed on the monthly outstanding balance was
9.3%.

                                       26

Pursuant to the Company's Credit Agreement more fully discussed in Note H, the
Company refinanced these lines of credit. The Credit Agreement includes a
working capital revolver of $25 million and expires on September 30, 2002.
Accordingly, the amounts outstanding under the existing lines of credit as of
September 30, 1996 have been reclassified to long-term senior debt in the
Company's Consolidated Balance Sheet.

        On October 1, 1996, the Company, together with MEDIQ/PRN entered into a
$260 million Credit Agreement with a group of lenders led by Banque Nationale de
Paris as Administrative Agent and Initial Issuing Bank and NationsBank, N.A. as
the Documentation Agent (the "Credit Agreement"). The Credit Agreement provides
for four separate loans, a Term A loan ($35 million), a Term B loan ($100
million), an Acquisition Revolver ($100 million) and a Working Capital Revolver
($25 million). The amounts available under the Credit Agreement allowed the
Company to refinance substantially all of its existing senior debt, its
outstanding lines of credit, all of MEDIQ/PRN's subordinated debt, and
MEDIQ/PRN's $100 million 12-1/8% Senior Secured Notes due 1999. Upon completion
of the financing, the Company had $40 million available

                                       27

<PAGE>

under the Acquisition Revolver and $10 million available under the Working
Capital Revolver both of which were available to the Company upon compliance
with certain financial covenants and/or ratios.

        The loans bear interest at either the prime rate plus a factor or at a
Eurodollar rate plus a factor. The factor changes quarterly based upon the
Company's leverage ratio. The Company's interest rate on the Term A loan, the
Acquisition Revolver and the Working Capital Revolver is prime (8.25% at
September 30, 1996) plus 1.25% or Eurodollar (5.38 % at September 30, 1996) plus
2.75% and the interest rate on the Term B loan is prime plus 1.75% or Eurodollar
plus 3.25%. The loans are collateralized by substantially all of the assets of
the Company. The proceeds from the sales of PCI, NutraMax, Mobile X-Ray and
Health Examinetics aggregating approximately $128 million must be utilized to
repay outstanding advances under the Acquisition Revolver upon receipt.

        The Term A loan is payable in quarterly installments of $1.2 million
beginning December 31, 1996 through September 30, 2001 and in quarterly
installments of $2.75 million from December 31, 2001 through September 30, 2002.
The Term B loan is payable in quarterly installments of $.25 million beginning
December 31, 1996 through September 30, 2002, quarterly installments of $8.5
million in fiscal 2003 and quarterly installments of $15 million in fiscal 2004.
The Company can borrow and repay under the Acquisition Revolver until March 31,
1998 in accordance with the Credit Agreement. On March 31, 1998, the Acquisition
Revolver converts to a term loan which will be repaid in quarterly installments
beginning on June 30, 1998. The first two installments will be at 5.0% of the
converted balance and all remaining quarterly payments will be at 5.625% of the
converted balance. The Working Capital Revolver terminates on September 30, 2002
at which time all outstanding balances are due.

        The Credit Agreement requires the Company to maintain certain financial
ratios and imposes certain other financial and dividend limitations. The terms
of the Company's Credit Agreement preclude the payment of cash dividends until
October 1, 1997.

        As a result of the refinancing, the Company recognized in the first
quarter of 1997, an extraordinary charge of $13 million before taxes resulting
from the write-off of deferred charges and premiums incurred related principally
to the tender offer to purchase the $100 million 12-1/8% Senior Secured Notes
due 1999, and a non-recurring charge of $11 million for the purchase of a
warrant to purchase 10% of MEDIQ/PRN issued in connection with financing the KCI
acquisition.

        Accordingly, the Company has reflected the outstanding balances of its
lines of credit, certain subordinated debt and Senior Secured Notes as long-term
senior debt on its Consolidated Balance Sheet at September 30, 1996.

        In accordance with the terms of the Credit Agreement, effective November
15, 1996, the Company entered into interest rate hedge transactions which
terminate in January 2000. Under one of these transactions, on $50 million of
borrowings, the Company's base Eurodollar borrowing rate is fixed at 6.26% per
annum, instead of a floating Eurodollar rate. Under the second hedge
transaction, on an additional $50 million of borrowings, the Company's base
Eurodollar rate cannot be lower than 5.25% or greater than 7.43%.

        The 7.5% debentures are exchangeable for an aggregate of 2,255,000
shares of NutraMax common stock owned by the Company, or an equivalent of $15.30
per share, and are redeemable in whole or in part at the option of the Company
after July 1996. Interest is payable semi-annually on January 15 and July 15. On
October 1, 1996, the Company repurchased $6.7 million of its 7.5% debentures in
the open market at a discount resulting in a pretax gain of $.4 million. This
gain was recorded in the first quarter of fiscal 1997 as an extraordinary item.

                                       28

<PAGE>


Note H - Long-Term Debt (Continued)

        The 7.25% debentures are convertible at any time prior to maturity into
shares of the common stock of the Company at $7.50 per share. Interest is
payable semi-annually on June 1 and December 1. Annual sinking fund payments are
scheduled to commence in June 1997. However, because of prior open market
purchases of these debentures, the Company will not be required to make the
initial sinking fund payments. The Company is also required to offer to
repurchase a portion of the debentures if stockholders' equity is $40 million or
less at the end of two consecutive fiscal quarters. Since June 30, 1994, the
Company's stockholders' equity has been less than $40 million. As of September
30, 1996, the Company is required to either repurchase or offer to redeem $11.25
million of the debentures in fiscal 1997. These debentures were reclassified to
long-term senior debt in connection with the terms of the refinancing discussed
above since the redemption of the 7.25% debentures must be made from drawings on
the Acquisition Revolver. In November and December 1996, the Company repurchased
an aggregate of $2.2 million of the debentures at approximately face value in
the open market. The Company is required to either repurchase or offer to redeem
$9.05 million of debentures prior to January 30, 1997 pursuant to the terms of
the mandatory redemption provisions of the indenture. The Company is required to
either repurchase or offer to redeem an additional $11.25 million of debentures
prior to July 30, 1997 and semi-annually thereafter until all of the debentures
are repurchased or stockholders' equity is more than $40 million.

        In connection with repayments of debt the Company realized an
extraordinary gain of $1.7 million, or $1.1 million net of taxes, in 1996.

Maturities of long-term debt giving effect to the refinancing described above
are as follows:

Note I - Commitments and Contingencies (Continued)

Total rent expense under operating leases was $5.2 million, $5.4 million and
$5.2 million in 1996, 1995 and 1994, respectively. The leases, which are for
terms of up to 5 years, contain options to renew for additional periods.

At September 30, 1996, rental equipment and machinery and equipment included
assets under capitalized lease obligations of $11.8 million, less accumulated
amortization of $3.6 million.

Purchase Commitments - Pursuant to a Distribution Agreement with a vendor dated
April 1, 1996, as amended, MEDIQ/PRN has agreed to purchase $7 million of
certain products by March 31, 1997. Through September 30, 1996, MEDIQ/PRN
purchased $3.5 million under such agreement.

Guarantees - The Company guarantees a loan of MEDIQ PRN/HNE, L.L.C. in the
aggregate amount of $7.5 million. To support the guarantee the Company has a
certificate of deposit in the amount of $1.0 million with the lender.

Investigations and Legal Proceedings - MEDIQ Imaging, the assets of which were
sold by the Company in August 1995, is presently the subject of a criminal and
civil investigation by the United States Attorney's Office for the District of
New Jersey and the Department of Health and Human Services. The investigation
has focused on advice given by certain MEDIQ Imaging employees to physician
customers of MEDIQ Imaging relating to the reassignment of certain Medicare
claims. The Company and MEDIQ Imaging voluntarily reported the issue to the U.S.
Government in January 1995 after learning that the advice given by the employees
may have been inconsistent with the regulations relating to reassignment. The
Company and MEDIQ Imaging have been cooperating in the investigation. In August
1995, in connection with the sale of MEDIQ Imaging, the Company provided the
U.S. Government with a guarantee of approximately $7.1 million in connection
with any settlement or judgment obtained by the U.S. Government. Management
believes that there has been no violation of any statute or regulation by MEDIQ
Imaging or any of its officers, directors or employees. Although the Company
believes there has been no violation, if the U.S. Government obtains a judgment,
the amount of the judgment against MEDIQ Imaging may exceed the guarantee
amount. However, management and outside counsel are not aware of any evidence
that would enable the U.S. Government to proceed against the Company beyond the
limits of the guarantee.

MEDIQ Mobile X-Ray Services, Inc., the assets of which the Company sold in
November 1996, is presently the subject of an investigation by the Wage and Hour
Division of the United States Department of Labor (the "DOL"). The DOL has
indicated that it believes that the practice of treating technologists as exempt
professionals is incorrect. The Company maintains that the practice of treating
x-ray technologists as exempt is correct and proper. A request for an official
position statement has been sent to the Wage and Hour Administrator of the DOL.
The DOL has indicated that it will broaden the scope of the investigation to
include technologists at other Mobile X-Ray locations. Potential liability is
retroactive from the day a lawsuit is initiated by the Solicitor of Labor and
could include double liquidated damages and penalties.

        On November 28, 1995, in the United States District Court for the Middle
District of Pennsylvania, ATS Medical Servces, Inc. ("ATS"), a former subsidiary
of the Company, and the president of ATS each pled guilty to one count of
misprision of a felony in violation of Title 18, United States Code, Section 4.
In addition, ATS agreed to repay the government $2.1 million, which was accrued
in fiscal 1994, for excess reimbursement received by ATS from the Medicare
Program from 1988 through 1992. The payment is part of a settlement agreement
entered into between ATS, the United States Government and Gerard Callie, a
former ATS employee, who had filed a civil lawsuit on behalf of the government
against ATS pursuant to the False Claim Act, Title 31, United States Code,
Sections 3729 - et seq., relating to ATS's alleged excess reimbursement. The
court sentenced ATS, on June 24, 1996, to a term of probation of two years. The
court imposed no fine on ATS. A mandatory special assessment of $200 was imposed
and paid by ATS. In November 1996, in connection with the sale of Mobile X-Ray,
the outstanding balance of this obligation was paid with a portion of the
proceeds of the sale.

On June 12, 1996, the Company, ATS and Mobile X-Ray were sued in the United
States District Court for the Middle District of Pennsylvania by Gerard and
Sharon Callie, who are both former employees of ATS. The lawsuit alleges that
the Callies were wrongfully terminated and asserts claims pursuant to the
whistleblower provisions of the False Claims Act and the Pennsylvania Wage
Payment and Collection Law. The plaintiffs made a demand for damages totaling
nearly $800,000. The Company believes it has no liability and intends to
vigorously defend this case.

Although the Company has recorded additional reserves aggregating $4.0 million
in 1996 based upon management's estimate of the eventual outcome of the
investigations and lawsuit discussed above, the ultimate outcome of the
investigations and lawsuit cannot presently be determined. These reserves are
included in the Company's reserve for disposal of discontinued operations.
Accordingly, no provision for any other loss that may result upon resolution of
these matters has been made in the Company's consolidated financial statements.

In addition, the Company has pending several legal claims incurred in the normal
course of business, which in the opinion of management, will not have a material
effect on the consolidated financial statements.

Note J - Fair Value of Financial Instruments

Estimated fair value of financial instruments is provided in accordance with the
requirements of SFAS No. 107, "Disclosures About Fair Value of Financial
Instruments". The estimated fair value amounts have been determined by the
Company using available market information and appropriate methodologies.
However, considerable judgment is necessarily required in interpreting market
data to develop the estimates of fair value. Accordingly, the estimates
presented herein are not necessarily indicative of the amounts that the Company
could realize in a current market exchange. The use of different market
assumptions and/or estimation methodologies may have a material effect on the
estimated fair value amounts.

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:

                Accounts receivable and accounts payable - The carrying amounts
of these items are an estimate of their fair values at September 30, 1996.

                Long-term debt (excluding capital lease obligations) - The fair
value of the Company's publicly traded debt is based on quoted market prices.
Interest rates that are currently available to the Company for issuance of debt
with similar terms and remaining maturities are used to estimate fair value for
debt issues for which quoted market prices are not available. The carrying
amount and estimated fair value of long-term debt are $216.2 million and $218.7
million, respectively.

The fair value estimates presented herein are based on information available to
management as of September 30, 1996, and have not been comprehensively revalued
for purposes of these financial statements since that date. Current estimates of
fair value may differ significantly from the amounts presented herein.

Note K  - Common and Preferred Stock

Series A preferred stock is convertible on a one-for-one basis into shares of
common stock, votes generally with the common stock as a single class, and in
all such votes, has ten votes per share. The preferred stock participates in
cash dividends at a rate equal to 60% of the amount paid on the common stock and
has a $.50 per share preference in the event of dissolution or liquidation.

Note O - Pension Plan

The Company maintains a noncontributory pension plan which provides retirement
benefits to substantially all employees. Employees generally are eligible to
participate in the plan after one year of service and become fully vested after
five years of service. The plan provides defined benefits based on years of
credited service and compensation. The Company makes contributions that are
sufficient to fully fund its actuarially determined cost, generally equal to the
minimum amounts required by ERISA. Assets of the plan consist primarily of
stocks, bonds and annuities.

Net periodic pension expense is comprised of the following:

                    (k) all Accounts Receivable of Seller from governmental
payors that by law may not be assigned to Buyer ("Non-Assignable Receivables")

the Non-Assignable Receivables shall be deemed to be Accounts Receivable).

               1.3 Assumption of Liabilities. (a) At Closing, Seller shall
transfer to Buyer, and Buyer shall assume and shall thereafter pay, perform and
discharge, to the extent not paid, performed and discharged at the Closing, all

accrued expenses of Seller that would be classified as current liabilities
("Current Liabilities") on a balance sheet of Seller as of the Closing Date
prepared in accordance with generally accepted accounting principles applied on
a basis consistent with the balance sheet delivered to Buyer and included in the
financial statements of Seller as at August 31, 1996 referred to in Section
3.1(e) ("GAAP"), other than: (A) any liabilities that Buyer is expressly not

Current Liabilities), (B) any liability due to Parent of the type included under

other Liabilities due to Parent or any of its Affiliates constituting Current
Liabilities shall be Assumed Liabilities), (C) any liability for taxes (other
than Buyer Taxes), (D) any obligation or liability arising out of any of the
Seller's Benefit Plans (as defined in Section 3.1(m)) except as provided in
Section 4.2(d), and (E) any obligation or liability to any Designated Employee
(as defined in Section 4.2(c)).

                    (ii) those obligations that arise or accrue under the
Contracts assigned by Seller to Buyer, with respect to, and only with respect
to, services to be rendered or goods to be supplied or benefits to be conferred
to or by Buyer or otherwise arising or accruing on or after the date that such
Contracts are assigned to Buyer. Notwithstanding the foregoing, Liabilities
under such Contracts that have accrued, or the performance of which is due, on
or prior to such date of assignment or which are in payment or consideration for
Excluded Assets, or that arise out of breaches that occurred prior to Closing,
shall remain the sole responsibility of Seller except to the extent such
liabilities constitute Current Liabilities; and

                    (iii) liabilities for severance or other payments related to
the termination of employment (as opposed to accrued compensation for services
rendered to Buyer) ("Employee Termination Payments") with respect to each
employee of Seller (other than the Subject Employees as hereinafter defined in
Section 4.1(b)) that Buyer employs as of the Closing Date through a date that
ends at least sixty (60) days after the Closing Date. Within ten (10) days of
request, Seller shall reimburse Buyer for any Employee Termination Payments paid
or incurred by it for any employee of Seller that Buyer terminates prior to the
end of such sixty (60) day period except to the extent such Employee Termination
Payments exceed $150,000. Subject to


                                   - 4 -

<PAGE>

the aforesaid reimbursement obligation of Seller, Buyer shall be responsible for
the payment of all Employee Termination Payments for all of Buyer's employees
that are so terminated. If Buyer shall terminate the employment of any such
employee prior to the end of such sixty (60) day period, then the Employee
Termination Payment with respect to such terminated employee shall include any
severance obligations with respect to such employee included in any Benefit
Plans, severance or employment agreement disclosed in the Disclosure Schedule
(and not constituting an Excluded Contract). If Buyer shall terminate the
employment of any such employee on or after the end of such sixty (60) day
period, then the Employee Termination Payment with respect to such terminated
employee shall exclude any severance obligations included in any Benefit Plan
but shall include any severance obligations with respect to such employees
included in any severance or employment agreement disclosed in the Disclosure
Schedule (and not constituting a Excluded Contract and not otherwise expressing
assumed by Seller pursuant to said agreement).

               (b) Buyer will not assume any, and Seller shall remain liable for
each, Liability of Seller existing on the Closing Date, other than the Assumed
Liabilities (the "Excluded Liabilities"). For purposes of this Agreement the
term "Liability" means any claim, lawsuit, liability, obligation or debt of any
kind or nature whatsoever, whether absolute, accrued, due, direct or indirect,
contingent or liquidated, matured or unmatured, joint or several, whether or not
for a sum certain, whether for the payment of money or for the performance or
observance of any obligation or condition, and whether or not of a type which
would be reflected as a liability on a balance sheet in accordance with
generally accepted accounting principles, including without limitation (i)
malpractice claims asserted by patients or any other tort claims asserted,
claims for breach of contract, or any claims of any kind asserted by patients,
former patients, employees or any other party that are based on acts or
omissions occurring on or before the Closing Date; (ii) amounts due or that may
become due to Medicare or Medicaid or any other health care reimbursement or
payment intermediary on account of Medicare or Medicaid cost report adjustments
or other payment adjustments attributable to any period on or prior to the
Closing Date (including, without limitation, any of the same which becomes due
to any nursing home, hospital, other facility or other third party pursuant to
any Contract directly, by reason of offset or indemnification, or otherwise, or
any other form of Medicare or other health care reimbursement denial, recapture,
adjustment or overpayment whatsoever with respect to any period on or prior to
the Closing Date), or any liabilities arising out of the Middle District of
Pennsylvania investigation of Seller, or out of any Questionable Payment (as
defined in Section 3.1(w)) ("Reimbursement Liabilities"), (iii) any obligation
or liability arising out of any Excluded Contract, unless and until it is
assigned to and assumed by Buyer in accordance with Section 1.4 and any
Liabilities arising out of any Excluded Asset, (iv) any obligation or liability
arising out of any United States Department of Labor (or any similar State
agency or department) investigation or claim with regard to any employment
matters of the Business, (v) any obligation or liability arising out of any
Seller's Benefit Plan (as such term is hereinafter defined in Section 3.1(m)),
(vi) any liabilities arising out of Taxes due or owing by Seller, including,
without limitation, to the extent such Taxes are accrued on the Closing Balance
Sheet, (vii) any obligation or liability arising out of any of the matters
described on Schedule 3.1(k) (viii) any obligation for bonus, unpaid vacation or
salary of any Subject Employee (as hereinafter defined) outstanding on the
Closing Date, except to the extent included as a Current Liability; (ix) any
liability or obligation arising out of any noncompliance with law

described in the Memorandum, dated April 26, 1996, to Harvey Z. Werblowsky from
Anne L. Thompson and Richard Wright; and (x) any liabilities due to Parent for
management fees for repayment of working capital or other advances, to the
extent such liabilities are not accrued on the Closing Balance Sheet.

               1.4  Assignment of Assets.

                    (a) Buyer agrees to assume and Seller agrees to assign to
Buyer all of the Contracts set forth on Schedule 3.1(j), except for the
Contracts set forth on Schedule 1.4(a) ("Excluded Contracts"). Notwithstanding
the foregoing, to the extent that any lease, contract, license, permit,
agreement, sales or purchase order, commitment, property interest, qualification
or other Asset described in Section 1.1, and not constituting an Excluded
Contract or otherwise excluded in Section 1.2, to be sold, assigned or conveyed
to Buyer, cannot be sold, assigned or conveyed, without the approval, consent or
waiver of any third person, or if such sale, assignment or conveyance or
attempted sale, assignment or conveyance would constitute a breach thereof or a
violation of any law, decree, order, regulation or other governmental edict
(collectively, "Impracticalities"), this Agreement shall not (unless and until
such Impracticality is resolved) constitute or require a sale, assignment or
conveyance thereof, or an attempted sale, assignment or conveyance thereof, and
each Contract covered by the foregoing sentence (a "Temporary Excluded
Contract") shall be deemed to be an Excluded Contract unless and until the
Impracticalities applicable to it are resolved. The foregoing sentence shall not
be deemed to limit any representation or warranty made by Seller pursuant to
this Agreement.

                    (b) Buyer and Seller shall each use commercially reasonable
efforts, and shall cooperate with each other, to resolve any Impracticalities
necessary to sell, assign or convey the Assets to Buyer as soon as practicable,
provided that neither Seller nor Buyer shall be required to expend money,
commence any litigation or offer or grant any accommodation (financial or
otherwise) to any third party.

                    (c) With respect to any asset, contract, lease, agreement,
permit, license, interest or other right of Seller (other than any Excluded
Contract) which is not included in the Assets assigned to Buyer at the Closing
by reason of the immediately preceding paragraphs of this Section 1.4, after the
Closing), (i) the parties shall cooperate with each other, upon written request,
in endeavoring to obtain the requisite third-party consent(s) to the assignment
thereof to Buyer (or the resolution of any other Impracticalities), without
either party being obligated, however, to make any payment to any such third
party which is not otherwise due in order to obtain such consent or resolution,
unless Buyer shall make such payment or agree to reimburse Seller for such
payment, and (ii) if any such requisite consent cannot be obtained, Seller shall
use its commercially reasonable efforts in endeavoring to obtain for Buyer, at
no cost to Seller, an arrangement reasonably acceptable to Buyer designed to
provide for Buyer the benefits thereof (subject to assumption and performance of
all related liabilities in some other manner reasonably acceptable to Buyer and
Seller to the extent they otherwise would be assumed by Buyer in accordance with
this Agreement but for the failure to obtain such consent or resolve such
Impracticality). A Temporary Excluded Contract shall cease to be an


                                   - 6 -

<PAGE>

Excluded Contract for the purposes of this Agreement and shall be assigned to
the Buyer when the Impracticalities applicable to it are resolved.

                    (d) Provided that Seller complies with its obligations under
Sections 1.4(b) and (c) above, Buyer agrees that Seller shall not have any
liability whatsoever arising out of or relating to the failure to obtain any of
the consents set forth on Schedule 3.1(j)-D.

                                  ARTICLE II
                          PURCHASE PRICE AND CLOSING

               2.1  Purchase Price.

                    (a) The aggregate purchase price for the Assets and for the
NonCompetition Agreement (as hereinafter defined in Section 5.5) shall be equal
to the sum of: (a) $10,502,347 payable at Closing (as hereinafter defined)
subject to the adjustment provided in Section 2.3 , which amount shall be
payable as follows: (i) FIVE MILLION THREE HUNDRED AND TWO THOUSAND THREE
HUNDRED AND FORTY-SEVEN DOLLARS ($5,302,347) shall be payable in cash; and (ii)
FIVE MILLION TWO HUNDRED THOUSAND DOLLARS ($5,200,000) shall be paid at the
Closing by delivery to Seller of newly issued shares of the Common Stock, par
value $.001 per share, of IHS (the "IHS Stock"), based upon the valuation and
subject to the terms and conditions of Section 2.9 below; and (b) the Contingent
Payment, as defined in Section 2.2(a) (collectively, the "Purchase Price"). The
cash portion of the Purchase Price shall be paid by wire transfer to an account
designated by Seller. Of the cash portion of the Purchase Price payable at
Closing, the outstanding balance of the $2,100,000 amount due to the United
States Government pursuant to the Settlement Agreement, dated as of September
25, 1995, shall be paid into an escrow account to be released to the United
States Government on behalf of Seller and Parent at Closing.

                    (b) The Purchase Price as adjusted pursuant to this
Agreement (and all other capitalizable costs) shall be allocated among the
Assets as shall be determined by Buyer, subject to the consent of Seller (which
consent shall not unreasonably be withheld, delayed or conditioned), in
accordance with Section 1060 of the Internal Revenue Code of 1986, as amended
(the "Code"). Each of the parties hereto agrees to prepare and file all tax
returns (including Form 8594) in a manner consistent with such allocation and to
report this transaction for Federal and state income tax purposes in accordance
with such allocation of the Purchase Price.

               2.2  Purchase Price Contingency.

<PAGE>

                    (a) A contingent payment of $2,000,000 (the "Contingent
Payment") shall be payable, if at all, only in the following amounts and as set
forth in Section 2.2(d):

                        (i) if there occurs any EKG Transportation Reimbursement
Change (defined below) with respect to any period prior to February 1, 1998,
then no portion of the Contingent Payment shall be paid;

                        (ii) if no EKG Transportation Reimbursement Change
occurs with respect to the period prior to February 1, 1999, then fifty percent
(50%) of the Contingent Payment shall be paid; and

                        (iii) if no EKG Transportation Reimbursement Change
occurs with respect to the period prior to February 1, 2000, then the balance of
the Contingent Payment shall be paid.

                    (b) If any portion of the Contingent Payment shall become
due in accordance with subparagraph (a) above, then the payment of such portion
shall be made thirty (30) days after the Date of Determination (hereinafter
defined) that such portion has become due. As used herein, the phrase "Date of
Determination" shall mean, with respect to any period in question, the earliest
to occur of: (i) the date on which the Health Care Finance Administration
("HCFA") or any other Applicable Authority (defined below) makes a final
determination (that is not in conflict with or being contested or appealed by
any action or proceeding by or before or threatened by any other Applicable
Authority) that any pending, threatened or currently contemplated EKG
Transportation Reimbursement Change will not be enacted, promulgated or
otherwise effectuated with respect to the period in question, and (ii) the last
day of the period in question if no EKG Transportation Reimbursement Change
shall have occurred or be so pending, threatened or currently contemplated with
respect to such period in question.

                    (c) As used herein, the phrase "EKG Transportation
Reimbursement Change" shall mean an alteration, modification or other change in
the amount of EKG transportation reimbursement paid with respect to the
operation of the Business before, on or after the Closing Date, from either
Medicare Part A or Part B, third party billing, facility billing or direct
billing, which alteration, modification or change: (i) results from any actions
taken by HCFA, Medicare, U.S. Congress or any U.S. Court (an "Applicable
Authority"); and (ii) has the effect of eliminating or reducing the
reimbursement amount which Seller (prior to Closing) or Buyer (after the
Closing) is paid for its services. Notwithstanding anything to the contrary
contained in this Section 2.2, no EKG Transportation Reimbursement Change shall
be deemed to have occurred if it shall only affect payments made or due to
Seller prior to Closing and that do not constitute any part of the Assets.

                    (d) If there shall be an EKG Transportation Change, but such
EKG Transportation Reimbursement Change shall be a reduction in the amount of
EKG transportation reimbursement paid with respect to the operation of the
Business as aforesaid by less than 40% of the amount payable on the date hereof,
then, in addition to the portion of the Contingent Payment which shall be paid
in accordance with subsection (a) above, if any, within thirty (30)


                                   - 8 -

<PAGE>

days after the Date of Determination of the amount of such EKG Transportation
Change, Buyer shall pay to Seller a portion of the Contingent Payment which has
not previously been paid in accordance with subsection (a), which portion shall
be equal to the percentage set forth in Column "Y" below of the amount not
previously paid which corresponds to the range of percentage reduction in EKG
transportation reimbursement set forth in column "X" below.

               2.3  Post-Closing Purchase Price Adjustment.

                    (a) In addition to any adjustment to the Purchase Price
arising under Section 2.2, the Purchase Price shall be further subject to
adjustment after Closing as follows: (i) if the Closing Date Working Capital (as
hereinafter defined) of Seller is less than $2,700,000 (the "Required Amount")
then the Purchase Price shall be reduced dollar-for-dollar by the amount of such
deficiency; and (ii) if the Closing Date Working Capital of Seller shall exceed
$2,700,000 then the Purchase Price shall be increased dollar-for-dollar by the
amount of such excess to the extent payable as provided in Section 2.3(b)(ii).
If the Closing Date Working Capital equals $2,700,000 there will be no
adjustment to the Purchase Price under this Section 2.3(a). As used herein, the
"Closing Date Working Capital" of Seller shall mean the excess of (x) the
aggregate amount of cash and accounts receivable, inventories and prepaid
expenses and other current assets of Seller, in each case, included in the
Assets on the Closing Balance Sheet (as such term is hereinafter defined) over
(y) the aggregate amount of current liabilities reflected on the Closing Balance
Sheet (excluding therefrom any portion thereof constituting Excluded
Liabilities). There shall be no accrual on the Closing Balance Sheet for any
bonuses due to any Subject Employee or for any bonuses arising out of the
consummation of the transactions contemplated by this Agreement, and all of such
liabilities shall be Excluded Liabilities. No accrual shall be made for Employee
Termination Payments.

                    (b) Regarding the Closing Balance Sheet. (i) At the Closing,
Seller shall deliver to Buyer the balance sheet of Seller and a calculation of
the amount of the Closing


                                   - 9 -

<PAGE>

Date Working Capital, certified by the Chief Financial Officer of the Seller to
be his or her best good faith estimate of such balance sheet and Closing Date
Working Capital as of the Closing (the "Preliminary Closing Date Balance
Sheet"). The Preliminary Closing Date Balance Sheet shall be prepared in
accordance with GAAP (the "Accounting Principles"). Buyer shall complete, at its
own expense, a review of such calculation of the Closing Date Working Capital
and shall deliver to Seller within ninety (90) days after the Closing, its
written report (the "Working Capital Review") setting forth the amount of such
Closing Date Working Capital as confirmed or determined in accordance with such
review. The Working Capital Review must be done in accordance with the same
Accounting Principles used by Seller. In the event that the Working Capital
Review delivered to Seller in accordance with the provisions of this Agreement
discloses that the Closing Date Working Capital was greater than $2,700,000, the
Purchase Price shall be deemed to have been increased by the amount of such
excess (the "Working Capital Increase"), provided that Buyer collects in respect
of Accounts Receivable (hereinafter defined) at least the Target Amount
(hereinafter defined). The "Target Amount" shall mean the amount of accounts
receivable that must be included as current assets in the Closing Date Working
Capital in order to obtain a Closing Date Working Capital amount equal to
$2,700,000. Any payment by Seller to Buyer of a Purchase Price adjustment
pursuant to clause (ii) below shall decrease the Target Amount by the principal
amount of such payment. In the event that the Working Capital Review delivered
to Seller in accordance with the provisions of this Agreement discloses that the
Closing Date Working Capital was less than $2,700,000, the Purchase Price shall
be deemed to have been reduced by the amount of such deficiency and Seller, upon
demand, shall immediately pay the amount of such deficiency to Buyer. If Seller
shall dispute the amount set forth in the Working Capital Review, it shall give
notice to Buyer (a "Delay Payment Notice") within thirty (30) days after
delivery to it of the Working Capital Review that the adjusting payment required
above should not then be made and setting forth in reasonable detail its
objections and the basis therefor, in which case the parties shall meet and in
good faith attempt to resolve any disagreements within thirty (30) days after
delivery to Buyer of the Delay Payment Notice. If Seller shall not have
delivered a Delay Payment Notice within such thirty (30) day period, Seller
shall be deemed to conclusively have accepted the determination of Buyer of the
amount of Working Capital as of the Closing Date, in which case such
determination shall be final and shall not be subject to further review,
challenge or adjustment, absent fraud. If Seller and Buyer cannot resolve any
such disputes, such disputes shall be resolved by KPMG Peat Marwick LLP or if
such firm is unable to so act or is not at the time independent of both Seller
and Buyer, by an independent nationally recognized accounting firm selected by
KPMG Peat Marwick LLP, which accounting firm is reasonably acceptable to both
Seller and Buyer (the accounting firm so engaged shall hereinafter be referred
to as the "Independent Accounting Firm"); provided, the Independent Accounting
Firm shall only resolve disputes properly raised in accordance with the
provisions of this Section 2.3. The Independent Accounting Firm shall be
directed to make its determination as promptly as practicable (and no later than
30 days after referral to it of such dispute by Seller and Buyer) and such
determination shall be final and binding upon Seller and Buyer. The expenses
relating to the engagement of the Independent Accounting Firm shall be borne by
the party against whom the Independent Accounting Firm shall rule; provided that
if it does not clearly rule in favor of either party, the expenses shall be
shared one-half by Seller and one-half by Buyer. For purposes of this Agreement,
the Closing Balance Sheet shall be as set forth in the Working Capital Review,
as accepted by Seller as set


                                   - 10 -

<PAGE>

forth above, or as modified by resolution of Seller and Buyer or by the
Independent Accounting Firm.

                        (ii) Any adjustment to the Purchase Price due to Buyer
pursuant to this Section shall be paid by Seller to Buyer (together with
interest on such amount from the date on which it shall become due to Buyer in
accordance with this Agreement until paid at a rate equal to 7% per annum)
within 10 days after the final determination of such adjustment is made. Subject
to subsection (c)(ii) below, any Excess Collections (hereinafter defined) shall
be paid by Buyer to Seller on the fifteenth business day of each calendar month
in an amount equal to all Excess Collections (hereinafter defined) during the
calendar month then most recently ended, and any such payments shall be first
applied against any Working Capital Increases and any excess shall thereafter be
paid to Seller. "Excess Collections" means the amount of Accounts Receivable
collected in excess of the Target Amount. If Buyer shall fail to timely pay any
such amount in accordance with the foregoing two sentences, then such amount
shall bear interest from the date on which it shall become so due to Seller
until paid at a rate equal to 7% per annum, and such interest shall be payable
upon demand.

                    (c) Accounts Receivable Collection and Reporting. (i)
Commencing 90 days after the Closing Date and continuing until the first
anniversary of the Closing Date, or if earlier, until all Accounts Receivable
shall have been collected, Buyer shall provide quarterly reports to Seller
regarding the amounts collected on the accounts receivable of the Business
outstanding as of the Closing Date (the "Accounts Receivable") and Buyer's
efforts to collect such accounts. Buyer shall, at Buyer's election, either (i)
apply at least the same efforts in the collection of the Accounts Receivable as
Buyer applies in the collection of its own accounts receivable or (ii) use
substantially the same personnel and procedures to collect the Accounts
Receivable as were used by the Business immediately prior to the Closing Date,
in the substantially same positions, with the substantially same
responsibilities and at the substantially same salaries and hours. Buyer shall
have no liability or responsibility to collect Accounts Receivable to the extent
Seller fails to deliver to Buyer such documentation as Buyer shall reasonably
request with respect thereto. The collection of all Accounts Receivable received
from an account debtor of the Business as of the Closing Date shall be applied
to the oldest outstanding invoice with such account debtor which is not then in
dispute consistent with Buyer's general overpayment policies; provided, however,
notwithstanding the foregoing, any payments made by an account debtor in respect
of a designated account shall be applied to the account so designated. For
purposes of the preceding sentence, a disputed invoice is an invoice that is the
subject of a written dispute from the account debtor which is reasonably
recognized by Buyer as disputed in accordance with its general policies; upon
the resolution of any such dispute, such invoice shall no longer be considered
disputed and collections from the account debtor shall be applied in accordance
with the previous sentence as if such dispute had not arisen. Provided that
Buyer has collected in respect of Accounts Receivable at least the Target
Amount, then on the fifteenth (15th) business day of each calendar month until
one month after the first anniversary of the Closing Date, Buyer shall provide
reports to Seller regarding the amounts collected on such Accounts Receivable
with respect to the preceding calendar month, and Buyer's efforts to collect
such accounts.

<PAGE>

                        (ii) In the event that Buyer has complied with its
collection obligations set forth in this paragraph (c) but has not collected at
least the Target Amount by the first anniversary of the Closing Date, (i) Buyer
shall notify Seller of the amount of such Accounts Receivable actually collected
by Buyer, (ii) Seller shall promptly remit to Buyer the amount, if any, by which
the amount of such Accounts Receivable actually collected is less than the
Target Amount (to the extent not already paid), and (iii) Buyer shall promptly
remit to Seller all amounts thereafter collected by Buyer in respect of the
Accounts Receivable.

               2.4 Closing Date. The closing (the "Closing") of the purchase and
sale of the Assets shall be held pursuant to overnight courier and escrow
arrangements acceptable to all parties hereto as of 12:01 a.m. on November 6,
1996 or on such other date or in such other manner as the parties may mutually
agree. The date on which the Closing shall occur is hereinafter referred to as
the "Closing Date".

               2.5 Closing Documents of Seller. At the Closing, Seller shall
deliver or cause to be delivered to Buyer the following documents:

amended to the Closing Date, certified by its Secretary and the Secretary of

reasonably necessary to convey title to all owned motor vehicles and the
registrations of all equipment included in the Assets to Buyer in a fashion
consistent with the provisions of this Agreement;

                    (e) the Records contemplated by Section 4.3;

                    (f) a certificate from the Chief Financial Officer of Seller
setting forth in reasonable detail the best good faith estimate of such Chief
Financial Officer of the Closing Date Working Capital;

                    (g) a certificate dated the Closing Date and signed by the
duly authorized signatories of Seller stating that the transactions contemplated
hereunder have been duly authorized and approved by Seller and certifying the

duly authorized signatories of Parent stating that the transactions contemplated

               2.9  IHS Stock.

                    (a) As set forth in Section 2.1(b) above, a portion of the
Purchase Price shall be payable by means of the delivery to Seller of IHS Stock
valued at $5,200,000 based upon a price per share (the "Initial Market Value Per
Share") of such stock equal to the average closing NYSE price of such stock for
the twenty (20) business day period ending on the date which is four (4)
business days prior to the Closing Date.

                    (b) Resale Limitations. All sales of IHS Stock issued
pursuant to this Agreement shall be effected solely through Smith Barney, Inc.,
as broker, and sales of such shares shall not at any time, in the aggregate,
exceed one-hundred thousand (100,000) shares during any thirty (30) day period.
The restriction on the number of shares that may be sold in accordance with this
subsection (b) shall lapse at such time as the Seller or the Parent shall have
sold at least 100,000 of such shares in accordance with this subsection (b). If
Smith Barney, Inc. shall be unable to act as the broker for any of such sales,
then IHS shall designate another broker that is reasonably acceptable to Seller
through which such sales shall be made.

                    (c) Investment Representations. All shares of IHS Stock to
be issued hereunder will be newly issued shares of IHS. Seller represents and
warrants to IHS and Buyer that the IHS Stock being issued hereunder is being
acquired, and will be acquired, by it for investment for its own account or the
account of the Parent, to whom transfer of any of such shares is expressly
permitted in accordance with this Agreement, and not with a view to or for


                                   - 14 -



<PAGE>

sale in connection with any distribution thereof within the meaning of the
Securities Act of 1933, as amended (the "Securities Act") or any applicable
state securities law; Seller acknowledges that the IHS Stock constitutes
restricted securities under Rule 144 promulgated by the Securities and Exchange
Commission (the "Commission") pursuant to the Securities Act, may have to be
held indefinitely and may not be sold, transferred, assigned, pledged or
otherwise disposed of except pursuant to an effective registration statement or
an exemption from registration under the Securities Act and the rules and
regulations thereunder. Seller and Parent have the knowledge and experience in
financial and business matters, are capable of evaluating the merits and risks
of the investment, and are able to bear the economic risk of such investment.
Seller and Parent have been provided with such materials as are generally
provided to shareholders of IHS and has had the opportunity to make inquiries of
and obtain from representatives and employees of IHS such other information
about IHS as they deem necessary in connection with such investment.

                    (d) Legends. It is understood that the certificates
evidencing the IHS Stock shall bear the following (or a similar) legend (in
addition to any legends which may be required in the opinion of IHS's counsel by
the applicable securities laws of any state):

               THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
               REGISTERED UNDER THE SECURITIES ACT OF 1933. THE SHARES HAVE BEEN
               ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD, TRANSFERRED OR
               ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
               FOR THESE SHARES UNDER THE SECURITIES ACT OF 1933 OR AN OPINION
               OF THE COMPANY'S COUNSEL THAT REGISTRATION IS NOT REQUIRED UNDER
               SAID ACT.

      Upon the written request of Seller and Parent, accompanied by a legal
opinion in form and substance and from counsel reasonably acceptable to IHS and
setting forth that the shares evidenced by the stock certificate are freely
transferable without registration under the Securities Act, IHS shall cause a
new certificate, evidencing such shares and that does not bear such legend, to
be issued to Seller or the Parent.

                    (e) Transfers. Upon prior notice to IHS, Seller shall be
permitted to transfer any of the shares of IHS Stock acquired by it pursuant to
this Agreement and the registration rights related thereto to Parent.

                    (f) Registration of IHS Stock. (i) IHS will use its best
efforts to cause to be prepared, filed and declared effective by the Commission
within sixty (60) to ninety (90) days following the Closing Date, a registration
statement for the registration under the Securities Act of the IHS Stock issued
to Seller pursuant to this Agreement, and IHS shall maintain the effectiveness
of such registration statement for a period of two (2) years following the date
on which it becomes effective, or for so long as Seller or Parent shall own any
of the IHS Stock issued pursuant to this Agreement, whichever shall occur first,
in each case except to the extent that such shares shall become freely
transferable without registration under the Securities Act. If the number of
shares of IHS Stock included in the Purchase Price shall be increased pursuant
to clause (ii) below, IHS shall, prior to the effective date of such
registration statement estimate the number of additional shares and shall use
its best efforts to include all of the newly issued shares in the registration
statement.


                                   - 15 -



<PAGE>




                        (ii) (A) As of the date that such registration statement
shall become effective, the number of shares of IHS Stock included in the
Purchase Price shall be adjusted so that the number of shares issued to Seller
pursuant to this Agreement shall have an aggregate fair market value (the
"Adjusted Fair Market Value") equal to $5,200,000 based upon a price per share
of such stock equal to the average closing NYSE price of such stock for the
twenty (20) business day period ending on the date which is two (2) business
days prior to such effective date (the "Adjusted Market Value Per Share").
Within five (5) business days after such effective date IHS shall deliver notice
(the "Adjustment Notice") to Seller of the Adjusted Fair Market Value, the
Adjusted Market Value Per Share and the number of shares to be delivered by
Buyer to Seller (if the Adjusted Market Value Per Share shall be less than the
Initial Market Value Per Share) or by Seller to Buyer (if the Adjusted Market
Value Per Share shall be greater than the Initial Market Value Per Share) so as
to effect the adjustment described in this clause (ii). The number of shares to
be delivered or issued, as the case may be, shall be rounded up or down so that
no fractional shares need be issued. Within five (5) business days the parties
shall make the delivery of the shares of IHS Stock required in the Adjustment
Notice.

                        (B) In lieu of (and not in addition to) the adjustment
set forth in paragraph (A) above, in addition to any other remedy available at
law, if the registration statement referred to in clause (i) above shall not
have been declared effective on or prior to the second anniversary of the
Closing Date and the Adjusted Market Value Per Share as of such second
anniversary date shall be less than Initial Market Value Per Share, then, the
adjustment set forth in paragraph (A) above shall be made as of such second
anniversary date.

                    (g) Registration Procedures, etc. In connection with the
registration rights granted to Seller with respect to the IHS Stock as provided
in this Section 2.9, IHS agrees as follows:

                        (i) IHS will promptly notify Seller at any time when a
prospectus relating to a registration statement covering Seller's shares under
this Section 2.9 is required to be delivered under the Securities Act, of the
happening of any event known to IHS as a result of which the prospectus included
in such registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing.

                        (ii) IHS shall furnish Seller with such number of
prospectuses as shall reasonably be requested, and Seller agrees to comply with
the prospectus delivery requirements of the Securities Act in connection with
any sale of IHS Stock by it.

                        (iii) IHS shall take all necessary action which may be
required in qualifying or registering IHS Stock included in a registration
statement for offering and sale


                                   - 16 -



<PAGE>

under the securities or Blue Sky laws of such states as reasonably are requested
by Seller, provided that IHS shall not be obligated to qualify as a foreign
corporation or dealer to do business under the laws of any such jurisdiction.

                        (iv) The information included or incorporated by
reference in the registration statement filed pursuant to this Section 2.9 will
not, at the time any such registration statement becomes effective, contain any
untrue statement of a material fact, or omit to state any material fact required
to be stated therein as necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading or
necessary to correct any statement in any earlier filing of such registration
statement or any amendments thereto. The registration statement will comply in
all material respects with the provisions of the Securities Act and the rules
and regulations thereunder. With respect to sales of IHS Stock sold in
accordance with the provisions of this Section 2.9 pursuant to the registration
statement, IHS shall indemnify Seller and its successors and assigns, and the
Parent, and each person, if any, who controls Seller within the meaning of ss.15
of the Securities Act or ss.20(a) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), against all loss, claim, damage, expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which any of them may
become subject under the Securities Act, the Exchange Act or any other statute,
common law or otherwise, based upon any untrue statement or alleged untrue
statement of a material fact contained in such registration statement executed
by IHS or based upon written information furnished by IHS filed in any
jurisdiction in order to qualify IHS Stock under the securities laws thereof or
filed with the Commission, any state securities commission or agency, NYSE,
NASDAQ, or any securities exchange; or the omission or alleged omission
therefrom of a material fact required to be stated therein or necessary to make
the statements contained therein not misleading, unless such statement or
omission was made in reliance upon and in conformity with written information
furnished to IHS by Seller or the Parent for use in such registration statement,
any amendment or supplement thereto or any application, as the case may be. If
any action is brought against Seller or any controlling person of Seller or the
Parent in respect of which indemnity may be sought against IHS pursuant to this
subsection, Seller or the Parent or such controlling person of Seller or the
Parent shall within thirty (30) days after the receipt thereof of a summons or
complaint, notify IHS in writing of the institution of such action and IHS shall
assume the defense of such action, including the employment and payment of
reasonable fees and expenses of counsel. Seller or any such controlling person
or the Parent shall have the right to employ its or their own counsel in any
such case, but the fees and expenses of such counsel shall be at the expense of
such Seller or such controlling person or such Parent unless (A) the employment
of such counsel shall have been authorized in writing by IHS in connection with
the defense of such action, or (B) IHS shall not have employed counsel to have
charge of the defense of such action, or (C) such indemnified party or parties
shall have reasonably concluded that there may be defenses available to it or
them which are different from or additional to those available to IHS (in which
case, IHS shall not have the right to direct the defense of such action on
behalf of the indemnified party or parties), in any of which events the


                                   - 17 -



<PAGE>

fees and expenses of not more than one additional firm of attorneys for Seller,
such controlling person and the Parent shall be borne by IHS and such law firm
shall be reasonably acceptable to IHS. Except as expressly provided in the
previous sentence, in the event that Seller, any such controlling person or any
the Parent assumes control of the defense of any such action or claim, IHS shall
not thereafter be liable to Seller or any such controlling person or the Parent
in investigating, preparing or defending any such action or claim. IHS agrees
promptly to notify Seller of the commencement of any litigation or proceedings
against IHS or any of its officers, directors or controlling persons in
connection with the resale of IHS Stock or in connection with such registration
statement. If the indemnification provided for in this Section 2.9 is held by a
court of competent jurisdiction to be unavailable to Seller or any controlling
person of Seller or any Parent with respect to any loss, liability, claim,
damage or expense referred to herein, then IHS in lieu of indemnifying Seller or
any controlling person of Seller or the Parent hereunder, shall contribute to
the amount paid or payable by Seller or any controlling person of Seller or the
Parent hereunder, as a result of such loss, liability, claim, damage, expense or
liability in such proportion as is appropriate to reflect the relative fault of
IHS on the one hand and of Seller or any controlling person of Seller or the
Parent on the other hand in connection with the statements or omissions which
resulted in such loss, liability, claim, damage, expense, or liability, as well
as any other relevant equitable considerations. The relative fault of IHS and of
Seller or any controlling person of Seller or the Parent shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission to state a material fact relates to
information supplied by IHS or by Seller or any controlling person of Seller or
the Parent and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

                        (v) Seller and Parent and their respective successors
and assigns, shall severally, and not jointly, indemnify IHS and Buyer, their
respective officers, directors and advisers, and each person, if any, who
controls IHS or Buyer within the meaning of ss.15 of the Securities Act or
ss.20(a) of the Exchange Act against all loss, claim, damage, expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Securities Act, the Exchange Act or any other statute, common
law or otherwise, arising from information that was furnished by or on behalf of
Seller, or the Parent or its, respective successors or assigns and which was
included in the selling shareholder provisions in such registration statement.
The indemnification rights set forth in this clause (v) shall be subject to the
same procedures as are to be applied to the indemnification rights set forth in
clause (iv) above, although references to Buyer and IHS on the one hand, and
Seller and Parent, on the other hand, shall be reversed.

               (h) Registration Expenses. Seller and the Parent shall not be
responsible for, and IHS shall bear, all of the reasonable expenses of IHS
related to such registration including, without limitation, the fees and
expenses of its counsel and accountants, all of its other costs, fees and
expenses incident to the preparation, printing, registration and filing under
the Securities Act of the registration statement and all amendments and
supplements thereto, the cost of furnishing copies of each preliminary
prospectus, each final prospectus and each amendment or supplement thereto to
underwriters, dealers and other purchasers of IHS Stock and the costs


                                   - 18 -



<PAGE>

and expenses (including fees and disbursements of its counsel) incurred in
connection with the qualification of IHS Stock under the Blue Sky laws of
various jurisdictions. IHS, however, shall not be required to pay underwriter's
or brokerage discounts, commissions or expenses, or to pay any costs and
expenses in excess in the aggregate of $20,000 for Blue Sky qualifications of
Seller's (and the Parent's) IHS Stock, or to pay any costs or expenses arising
out of Seller's or the Parent's failure to comply with its obligations under
this Section 2.9.

                    (i) Notice of Sale. Except for transfers permitted under
Section 2.9(e), above, if the Seller (or the Parent) desires to transfer all or
any portion of its IHS Stock, Seller (or the Parent, as the case may be) will
deliver written notice to IHS, describing in reasonable detail its intention to
effect the transfer and the manner of the proposed transfer.


                                  ARTICLE III
                        REPRESENTATIONS AND WARRANTIES

                        3.1 Representations and Warranties of Seller and Parent.
Seller and Parent hereby, jointly and severally, represent and warrant to Buyer
as follows:

                    (a) Authority. This Agreement and each of the certificates,
instruments, agreements and documents executed and delivered by Seller or Parent
pursuant to this Agreement (Seller's "Transactions Documents") have been duly
executed and delivered by Seller and Parent and constitute the legal, valid and
binding obligations of Seller and Parent enforceable against each of them, in
accordance with their respective terms. The Seller and Parent have all requisite
corporate power and authority to enter into this Agreement and each Seller's
Transaction Document and to consummate the transactions contemplated hereby and
thereby. All corporate acts and other proceedings required to be taken by the
Seller and Parent to authorize the execution, delivery and performance of this
Agreement and each Seller's Transaction Document and the consummation of the
transactions contemplated hereby and thereby have been duly and properly taken.
The execution and delivery of this Agreement and the Seller's Transaction
Documents do not, and the consummation of the transactions contemplated hereby
and thereby and compliance with the terms hereof and thereof will not: result in
any violation of or default, under, or require any consents or approvals under
(i) any material note, bond, mortgage, indenture, deed of trust, license, lease,
contract, commitment or agreement to which Seller or the Parent is a party or by
which any of their respective properties are bound except as set forth on
Schedule 3.1(a), (ii) any provision of the Certificate of Incorporation or
Bylaws of Seller or Parent and (iii) any judgment, injunction, order or decree,
or material statute, law, ordinance, rule or regulation applicable to Seller or
Parent, or the property or assets of Seller or Parent.

                    (b) Organization and Standing of Seller and Parent. Seller
and Parent are each a corporation duly organized and validly existing under the
laws of Delaware. Seller


                                   - 19 -



<PAGE>

has full corporate power and authority and possesses all material governmental
franchises, licenses, permits, authorizations and approvals necessary to enable
it to use its corporate name and to own, lease or otherwise hold its properties
and assets and to carry on its business in all material respects as presently
conducted. Seller is duly qualified and in good standing to do business in each
jurisdiction set forth on Schedule 3.1(b) and Seller is not doing business and
none of the Assets are located in any other jurisdiction where the failure to be
so qualified and in good standing would have a Material Adverse Effect. Seller
and Parent have delivered to Buyer true and complete copies of the Certificates
of Incorporation, as amended to date, and the Bylaws, as in effect on the date
hereof, of Seller and Parent.

                    (c) Ownership. Parent owns of record and beneficially all of
the outstanding capital stock of Seller.

                    (d) Subsidiaries of the Seller. Seller does not, directly or
indirectly, own any stock of, or any other interest in, any other corporation or
business entity (including, without limitation, joint ventures and
partnerships).

                    (e) Financial Statements. Schedule 3.1(e) sets forth the
unaudited consolidated balance sheets of Seller as of September 30, 1994 (the
"1994 Balance Sheet"), September 30, 1995 (the "1995 Balance Sheet"), July 31,
1996, and August 31, 1996 (the "Balance Sheet"), and the unaudited consolidated
statements of income, shareholders' equity, and cash flows of Seller for the
periods ended September 30, 1994, September 30, 1995, July 31, 1996, and August
31, 1996 (collectively, the "Financial Statements"). The Financial Statements
have been prepared in accordance with the books and records of Seller and
present fairly, in all material respects, the financial position and operations
as of September 30, 1994, September 30, 1995, July 31, 1996, and August 31, 1996
and the results of operations and cash flows of Seller for the periods then
ended in conformity with generally accepted accounting principles, consistently
applied, except for (i) the absence of certain notes which would otherwise be
required by generally accepted accounting principles and (ii) no accrual has
been made in connection with the governmental inquiries described on Schedule
3.1(e). Except as set forth on Schedule 3.1(e), the income statements included
in the Financial Statements do not contain any material items of special or
nonrecurring income or expense or any other income not earned or expense not
incurred in the ordinary course of business except as expressly specified
therein, and, except as so set forth, such financial statements include all
adjustments, which consist only of normal recurring accruals, necessary for such
presentation. Except under general principles of successor liability law
(including, without limitation, such principles arising under applicable
healthcare law), there is no basis for the assertion against Seller of any
material Liability of any nature or in any amount (other than Liabilities
reflected on the Balance Sheet or as have been incurred since the date of the
Balance Sheet in the ordinary course of business consistent with past practice)
for which Buyer may become liable.

<PAGE>

                    (f) Taxes.

                        (i) For purposes of this Agreement, (A) "Tax" or "Taxes"
shall mean all Federal, state, local and foreign taxes, charges and assessments,
including all interest, penalties and additions imposed with respect to such
amounts and (B) "Code" shall mean the Internal Revenue Code of 1986, as amended.

                        (ii) Seller has filed or caused to be filed in a timely
manner (within any applicable extension periods) all Tax returns, reports and
forms required to have been filed by the Code or by applicable state, local or
foreign Tax laws, rules, regulations and orders (collectively, "Returns") other
than those the failure which to file would not have a Material Adverse Effect;
all Taxes shown to be due on such Returns have been timely paid in full; and no
tax Liens have been filed and no material claims are being asserted in writing
with respect to any Taxes, except as set forth on Schedule 3.1(f). True and
complete copies of all Returns with respect to income or sales or use for any
period during the two-year period ending on the date hereof have been delivered
to Buyer, and as of the time of filing, the Returns correctly reflected in all
material respects or will correctly reflect in all material respects the facts
regarding the income, business, assets, operations, activities and status of
Seller and any other information required to be shown therein.

                    (g) Assets Other than Real Property. Schedule 3.1(g) sets
forth a complete description and list of all of Seller's motor vehicles, all
x-ray, EKG and other equipment, all computers, all office furniture and each
other item of tangible personal property included in the Assets that has a fair
market value of at least $500. Except as disclosed on Schedule 3.1(g) hereto,
Seller has such title to all Assets comprising personal property, tangible or
intangible, reflected on the Balance Sheet or thereafter acquired, except those
since sold or otherwise disposed of in the ordinary course of business,
consistent with past practice, as is necessary to permit the use and enjoyment
of such assets and properties in the same manner as used and enjoyed by Seller
and none of such Assets are subject to any liens, claims, security interests,
mortgages, pledges, charges, easements, rights of setoff, restraints on
transfers, restrictions on use, options, conditional sale agreements, subleases,
sublicenses or encumbrances of any kind or nature whatsoever ("Liens"), other
than Permitted Liens. For the purposes of this Agreement, "Permitted Liens"
means: (i) each lien set forth on Schedule 3.1(g) hereto; (ii) carriers',
warehouseman's, mechanics, materialmen's, repairmen's or other like liens
arising in the ordinary course of business which are not overdue for a period of
more than 30 days; (iii) deposits to secure the performance of bids, trade
contracts (other than for borrowed money), leases, statutory obligations, surety
and appeal bonds, performance bonds and other obligations of like nature
incurred in the ordinary course of business, provided that each such deposit
shall be included in the Assets and shall not exceed $15,000 in any one case, or
$75,000 in the aggregate; (iv) pledges or deposits in connection with worker's
compensation, unemployment insurance, and other social security legislation; and
(v) capitalized financing leases to the extent reflected on the Balance Sheet
and copies of which have been delivered to Buyer. No person


                                   - 21 -



<PAGE>

other than Seller has any right to the use or possession of any of such property
(other than in the ordinary course of business in accordance with contractual
rights) and no currently effective financing statement (other than Permitted
Liens) with respect to such personal property has been filed in any
jurisdiction, and (other than Permitted Liens) Seller has not signed any such
financing statement or any security agreement authorizing any secured party
thereunder to file any such financing statement. All of such personal property
owned by Seller and necessary to the operation of the Business, or currently
being used by Seller in the operation of the Business, comprising equipment,
improvements, furniture, vehicles and other tangible personal property, whether
owned or leased, is in good operating condition and repair except for normal
wear and tear in the ordinary course of business. The Assets, other than the
Excluded Assets, represent all of the assets, including without limitation, all
property (real, personal and mixed), licenses, intellectual property, permits
and authorizations, contracts, leases and other agreements that are owned by
Seller, and include all of the Assets owned by Seller, other than any Excluded
Assets, that are necessary or material to the operation of the Business as now
operated (the "Necessary Assets"). The preceding sentence shall not apply to

                                   COVENANTS

            4.1 Covenants of Seller. Seller covenants and agrees as follows:

                  (a) Insurance. Effective as of the Closing Date and for a
period of three (3) years thereafter, Seller at its own expense shall purchase
and maintain a tail insurance policy with respect to all claims-made insurance
policies of Seller currently in effect, such tail coverage to name Seller as
insured and Buyer as an additional insured.

                  (b) Employment Agreements. In the event that Buyer terminates
the employment (including upon expiration of the Initial Term (as such term is
defined in the Employment Agreements) if Buyer elects not to extend the Initial
Term pursuant to the applicable Employment Agreement) of any of William Glynn,

<PAGE>

Manty (the "Subject Employees") at any time after the one year anniversary of
the Closing Date and on or prior to the expiration of the Initial Term (as such
term is defined in such Employment Agreement), Seller will be solely responsible
for the payment of any compensation, severance, benefits, or other amounts
becoming thereafter due to such terminated Subject Employee solely under
Employment Agreements between Seller and the Subject Employees in an amount not
to exceed the aggregate amount that would have been due had such Employment
Agreements not been amended or modified on or after the Closing Date; provided
however, that any liability to any Subject Employee that constitutes a Current
Liability on the Closing Balance Sheet shall be Buyer's responsibility. Any
liabilities or obligations of any nature to the Subject Employees arising out of
any matters occurring after the Closing or arising out of such Employment
Agreements, other than those arising under the preceding sentence (or as
expressly assumed by Seller under the applicable Assignment and Amendment of
Employment Agreement) shall be the sole liability and responsibility of Buyer.
Buyer's liabilities under this Section 4.1(c) shall be Assumed Liabilities. Any
liability to Stephen Manty expressly assumed by Seller under paragraph 3 of his
Assignment and Amendment of Employment Agreement shall be an Excluded Liability.

                  (c) COBRA. Seller shall give all notices, make all offers, pay
and collect all premiums, obtain all group health plan coverage, and perform all
other actions mandated by Title X of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA"), which are required to be given, made,
paid, obtained, and performed as a result of the Closing under this Agreement.
This provision shall not be construed, however, to require Seller to maintain
its group health insurance coverage following Closing, except as may be required
by applicable Governmental Requirements or Section 4.2(c).

            4.2 Covenants of Buyer.  Buyer covenants and agrees as follows:

                  (a) Financial Information. Buyer will use reasonable
commercial efforts to (i) hold all of the books and records of Seller delivered
to it and existing on the Closing Date and not destroy or dispose of any thereof
for a period of three (3) years from the Closing Date, and thereafter if it
desires to destroy or dispose of such books and records, will offer first in
writing at least 60 days prior to such destruction or disposition to surrender
them to Parent, provided that such books and records must be held as
confidential information by Parent and Parent must state the reason it wants
possession of the books and records, and (ii) promptly provide to Parent upon
request, financial information provided to it by Seller with respect to Seller
for the period of the current fiscal year up to Closing in accordance with past
practice to allow Parent to comply with securities law, financial and tax
reporting and accounting requirements.

                  (b) Accounts. Buyer shall pay to Parent all amounts owed to
Parent by Seller on the Closing Date to the extent such amounts constitute
Assumed Liabilities when they shall become due in the ordinary course of
business consistent with past practice.

                  (c) Employees. Buyer undertakes to offer employment to all
employees of Seller other than two (2) employees to be designated by Buyer (the
"Designated Employees"), on such terms and with such benefits and compensation
as Buyer shall deem advisable in its sole discretion. Buyer agrees, at Seller's
prior written request, to use its reasonable commercial effort to continue
(until no later than March 31, 1997) the employment of Ms. Perez-Lugones after
the date which is thirty (30) days after the date hereof to provide Seller with
such assistance as it shall reasonably request of her (within the scope of her
employment arrangement or agreement with Buyer); provided that Seller shall be
liable for all compensation to, and costs and expenses payable with respect to,
such employee with respect to any period during which said employee is employed
by Buyer at Seller's request, and if Seller requests that Buyer continue such
employment, Buyer shall be entitled to reimbursement for any Employment
Termination Payment due to such employee to the extent provided in Section
1.3(a)(iii) regardless of when she is thereafter terminated.

                  (d) Insurance. The disability, life, health, dental and vision
insurance plans of Seller described on Schedule 3.1(l) shall constitute
Contracts and shall be assigned to, and assumed by, Buyer as provided in Section
1.4 of this Agreement.

            4.3 Mutual Covenants. Each of Seller and Buyer, as applicable,
covenants and agrees as follows:

                  (a)   Records.

                        (i) On the Closing Date, Seller shall cause to be
delivered to Buyer all Records and, to the extent transferred hereunder, the
items described in Section 1.1(a)(viii), in the possession of Seller relating to
the Business to the extent not then in the possession of Seller, subject to the
following exceptions:

                              (A) Buyer recognizes that certain Records may
contain incidental confidential information relating to Parent and not relating
to Seller, and that Seller may delete and retain such information from such
Records; and

                              (B) Seller may retain all bids received from other
parties and analyses relating to Seller.

                        (ii) Upon reasonable written notice, Buyer and Seller
agree to furnish or cause to be furnished to each other and their
representatives, employees, counsel and accountants access, during normal
business hours, such information (including Records pertinent to Seller) and
assistance relating to Seller as is reasonably necessary for financial reporting
and accounting matters, the preparation and filing of any Returns or the defense
of any Tax claim or assessment or the defense or prosecution of any litigation
matters; provided, however, that such access does not unreasonably disrupt the
normal operations of Buyer, Seller or any of their Affiliates.

                        (iii) Buyer agrees that it will use its commercially
reasonable efforts to make available to Seller the services of Stephen Manty (to
the extent he shall continue to be employed by Buyer and within the scope of his
Employment Agreement with Buyer) and/or his designees for the time period
commencing on the date hereof and ending on March 31, 1997 to assist Seller with
the defense of litigation matters and any investigation by the Department of
Labor and oversight of accounting matters; provided that Seller shall pay to
Buyer an amount equal to $4,000 per month in respect thereof and such services
to Seller shall not materially interfere with the performance of his obligations
to Buyer under his Employment Agreement.

                  (b) Publicity. Seller (and Parent) and Buyer (and IHS) agree
that no public release or announcement concerning the transactions contemplated
hereby shall be issued by either of them without the prior consultation and
written consent (which consent shall not be unreasonably withheld) of the other,
except such release or announcement as may be required by law or the rules or
regulations of any United States or foreign securities exchange, in which case
the party required to make the release or announcement shall allow the other
party reasonable time to comment on such release or announcement in advance of
such issuance.

Transaction Documents, and none of Parent, Seller, or any other person will have
or be subject to any liability to Buyer or any other person resulting from the
distribution to Buyer, or Buyer's use of, any such information (including,
without limitation, any offering memorandum, brochure or other publication
provided to Buyer, and any other document or information provided to Buyer in
connection with the transactions contemplated hereby).

            5.2 Further Assurances. From time to time, as and when requested by
either party hereto, the other party shall execute and deliver, or cause to be
executed and delivered, all such documents and instruments and shall take, or

<PAGE>

transfer taxes, documentary stamp taxes, recording charges and other fees and
taxes imposed by any governmental entity in connection with the transfer of the
Assets ("Buyer Taxes").

            5.4 Use of Mediq Name. Buyer acknowledges and agrees that the name
and service mark "MEDIQ" and all derivations thereof (the "Name") is owned by
Parent and that by the sale of the Assets, or otherwise, Parent is not
relinquishing any interest in or rights to the Name or any derivation thereof,
nor permitting Buyer (after the Closing Date) to use, license or otherwise have
any rights in or to the Name, except on such terms as are expressly set forth in
this Section. Parent will permit use of the Name by Buyer for transition
purposes during a period not to exceed 365 days subsequent to the Closing Date

                  (a) By the end of the Transition Period, Buyer shall have
caused the removal in all material respects of the Name from all of Buyer's
assets, motor vehicles, machinery, equipment, stationery, business cards, and

                  (b) Within a reasonable period of time after the Closing Date,

            5.5 Covenant Not to Compete.

                  (a) Each of Parent and Seller agrees that for a period of 3
years after the Closing Date neither of them nor any of their respective
Affiliates shall, directly or indirectly, for himself, herself or itself, or on
behalf of any other person, firm, entity or other enterprise, be employed by, be
an officer, director or manager of, act as a consultant for, be a partner in,
have a proprietary interest in, or loan money to any person, enterprise,
partnership, association, corporation, limited liability company, joint venture
or other entity which is directly or indirectly in the business of owning,
operating or managing any mobile radiological, EKG, or any other business
currently conducted by Seller (the "Applicable Businesses"), now or hereafter
competitive with any such Applicable Business of Buyer (including, without
limitation, the Business), IHS or any of their respective Affiliates, located in
any state in which Buyer, IHS or Seller is currently conducting such business;
provided, however, that nothing contained herein shall restrict Seller from
performing its obligations under any Temporary Excluded Contracts as provided in
Section 1.4(c) or restrict Parent or any of its Affiliates from operating or
owning any of their existing businesses or investments or renting or leasing any
equipment, provided that they do not expand into the foregoing prohibited
activities. The restrictions contained in this Section 5.5 (other than the
confidentiality provisions) shall not be binding upon any third party


                                   - 35 -



<PAGE>

purchaser of Parent, or of any assets, stock, division or business unit of
Parent or of any Affiliate of Parent.

                  (b) Seller and Parent represent and warrant that there are no
employees, consultants or agents of Parent having expertise in the operation of
the Applicable Business or having a relationship with any customers of the
Applicable Business. Notwithstanding anything to the contrary contained in this
Agreement, the foregoing representation and warranty and all indemnification
rights with respect thereto shall not expire until the date that is three (3)
years after the date hereof.

                  (c) Seller and the Parent hereby agree that, for a period of
three (3) years following the date hereof, without the express written consent
of IHS, none of Seller, the Parent and their respective Affiliates will directly
or indirectly, for themselves or on behalf of any other person, firm, entity or
other enterprise:

            (i) solicit any client, facility or patient who, prior to the date
hereof, was a client, facility or patient of Seller with respect to the
Applicable Business; or

            (ii) hire, entice away or in any other manner persuade any employee,
consultant, representative or agent who was an employee, consultant,
representative or agent of Seller prior to the date hereof, to alter, modify or
terminate their relationship with Buyer or IHS.

                  (d) The Parent and Seller each acknowledges that the
restrictions contained in this Section 5.5 are reasonable and necessary to
protect the legitimate business interests of Buyer and IHS and that any
violation thereof by either of them would result in irreparable harm to Buyer
and IHS, and that damages in the event of such a breach will be difficult, if
not impossible, to ascertain. Accordingly, the Parent and Seller each agrees
that upon the violation by it of any of the restrictions contained in this
Section 5.5, Buyer and IHS shall be entitled to obtain from any court of
competent jurisdiction a preliminary and permanent injunction as well as any
other relief provided at law, equity, under this Agreement or otherwise, without
the necessity of posting any bond or other security whatsoever. In the event any
of the foregoing restrictions are adjudged unreasonable in any proceeding, then
the parties agree that the period of time or the scope of such restrictions (or
both) shall be adjusted to such a manner or for such a time (or both) as is
adjudged to be reasonable.

                  (e) The Parent and Seller each acknowledges that the covenants
contained in this Section 5.5 are independent covenants and that any failure by
the Buyer or IHS to perform its obligations under this Agreement shall not be a
defense to enforcement of the covenants contained in this Agreement, including
but not limited to a temporary or permanent injunction.

necessary, including, without limitation, commencement of legal proceedings, to
enforce each of the non-competition agreements set forth on Schedule 1.4(a)
hereto upon the request of and in accordance with the instructions of Buyer.
Seller and Parent shall not be required to advance or expend any funds in
connection with their respective obligations under this subsection (f). Buyer

            5.6   Restrictions.

                  (a) From and after the Closing Date, neither Seller nor the
Parent shall disclose, directly or indirectly, to any person or entity, or make
use of, without the express authorization of IHS and Buyer, any non-public
pricing strategies or records acquired by Buyer from Seller, any proprietary
data or trade secrets acquired by Buyer from Seller or any financial or other
information acquired by Buyer from Seller; provided that the foregoing
restrictions shall not apply to any information which:

                        (i) is or becomes publicly known through no wrongful act
on the part of Seller or Parent; or

                        (ii) is or becomes available to the disclosing party on
a non- confidential basis from a third party without restriction and without
breach of this Agreement; or

                        (iii) is approved for release by written authorization
signed by Buyer or IHS; or

                        (iv) is required to be disclosed in accordance with
applicable law; provided, however, prior to making any such disclosure the party
required to make such disclosure shall provide Buyer with prompt notice of such
requirement to enable Buyer to seek an appropriate protective order and such
party will use its best efforts to preserve the confidentiality of such
information and will disclose only that portion of the information as is
required to be disclosed.

                  (b) Each of Seller and Parent acknowledges that the
restrictions contained in this Section 5.6 are reasonable and necessary to
protect the legitimate business interests of Buyer and IHS, and that any
violation thereof by any of them would result in irreparable harm to Buyer and
IHS. Accordingly, each of Seller and Parent agrees that upon the violation by
any of them of any of the restrictions contained in this Section 5.6, Buyer and


                                   - 37 -

                        (i) If the Medicare carrier for the States of Maine,
Massachusetts, New Hampshire or Vermont (each, an "Applicable State"): increases
the reimbursement rate for the transport component for mobile x-ray or EKG
services performed by Seller prior to the Closing Date, then the difference
between the amount due with respect to the transport component for mobile x-ray
or EKG services performed by Seller in all Applicable States prior to the
Closing Date at the increased rate of reimbursement shall be deemed to be an
Account Receivable, and accordingly, Seller shall be entitled to additional
Purchase Price payments if and to the extent provided in Section 2.3(b)(ii)
above; provided that such increases in Purchase Price by reason of this Section
5.7(a) shall not exceed $800,000 in the aggregate.

                  (b) Buyer and IHS shall cooperate and use their commercially
reasonable efforts to collect any amounts that shall become due to Seller as
contemplated by subsection (a) above, including, without limitation,
resubmitting billing if necessary, but only to the extent that Seller has
specifically identified and compiled and delivered to Buyer all of the necessary
bills and records.

                  (c) Seller shall have the right to assume the prosecution of
any action, suit, claim, proceeding or investigation relating to an increase in
the Medicare reimbursement rate for the transport component for mobile x-ray or
EKG services in the Applicable States that could result in an Account Receivable
(as provided in subsection (a) above) (each, an "Action") in a manner consistent
with the prosecution of similar Actions with respect to such reimbursement rates
in the Applicable States by other businesses in the Seller's industry in such
Applicable States, and Buyer and Seller agree to cooperate in good faith with
each other and shall not have the right to compromise or settle an Action
without the other's consent (which shall not be unreasonably withheld or
delayed).

            5.8 Audit. Following Closing, Seller and the Parent will cooperate
with and assist Buyer in a review of the financial statements of Seller. Buyer

to act as Seller's exclusive authorized agent to bill and collect all
Non-Assignable Receivables, and Buyer and Seller hereby agree that the proceeds
of such Non-Assignable Receivables shall be distributed in accordance with the
provisions of Section 1.1 and 2.3(b) above.

<PAGE>

                  (b) Buyer shall not receive a fee or any other compensation
for said billing and collection services.

                  (c) Seller hereby constitutes and appoints Buyer its true,
lawful, and irrevocable attorney to demand, receive, and enforce the billing and
collection of the NonAssignable Receivables, and to give receipts, releases, and
satisfactions for the same.

            5.10 Benefits under Excluded Contracts. If Buyer is provided with
any requested benefit under an Excluded Contract (such as use of space or access
to programs available with respect to leased motor vehicles), Buyer shall
reimburse Seller for its proportionate out-of-pocket cost of providing such
benefit.

                                INDEMNIFICATION

            6.1 Indemnification by Seller and Parent. (a) Seller and Parent
hereby jointly and severally agree to indemnify Buyer, IHS and their respective
Affiliates and their respective officers, directors, employees and agents
against and hold them harmless from any loss, liability, claim, damage or
expense (including reasonable legal fees and expenses but excluding punitive
damages and unforeseen or other consequential damages other than punitive
damages and unforeseen or other consequential damages which are paid to third
parties) (a "Loss") suffered or incurred by any such indemnified party, as a
direct consequence of (i) any breach of any representation or warranty of Seller

Seller contained in this Agreement or any Transaction Document, (iii) all
Reimbursement Liabilities; (iv) any Loss relating to any Excluded Liability

with COBRA or any like statute; (vii) any Loss that is attributable to the
pre-Closing conduct by Seller and relates to matters presently being
investigated by the U.S. Department of Labor with respect to Seller; and (viii)
any and all actions, suits, proceedings, demands assessments, judgments,
settlements (to the extent approved by Seller, such approval not to be
unreasonably withheld, delayed or conditioned) costs and legal and other
expenses incident to any of the foregoing; provided, however, that Seller shall
not have any liability under clause (i) above until the aggregate of all Losses,
for which Seller would, but for this proviso, be liable exceeds on a cumulative
basis $100,000, upon which Seller shall be liable for such $100,000 amount and
all other amounts under this Section 6.1; provided, further, that the aggregate
liability of Seller hereunder with respect to any and all Losses shall be
limited to the aggregate amount of the final Purchase Price.

                  (b) Buyer acknowledges and agrees that its sole and exclusive

<PAGE>

                  (c) Buyer acknowledges and agrees that Parent and Seller shall
not have any liability under any provision of this Agreement for any Loss to the
extent that such Loss is caused by actions taken by or omitted to be taken by
Buyer after the Closing Date. Buyer shall take and cause its Affiliates to take
all reasonable steps to mitigate any Loss to the extent the same would have been
required by applicable law if Buyer's rights to compensation for damages arose
under law rather than by reason of contractual rights.

                  (d) Buyer may offset any of its indemnification claims against
payment of the Contingent Payment (as defined in Section 2.2), provided that if
Seller disputes the claim, Buyer shall place the amount of the claim into an
escrow account with a nationally recognized financial institution, until the
dispute is settled under the procedures set forth in this Article VI.

            6.2 Indemnification by Buyer. (a) The Buyer hereby agrees to
indemnify Parent, Seller and their Affiliates against and hold them harmless
from any Loss suffered or incurred by any such indemnified party as a direct
consequence of (i) any breach of any representation or warranty of Buyer
contained in this Agreement or any Transaction Document, which by the terms of
Section 8.3 survives the Closing, (ii) any breach of any covenant of Buyer
contained in this Agreement or any Transaction Document, (iii) any guarantee or
obligation to assure performance given or made by Parent or any of its
Affiliates with respect to any obligation or liability of the Business that
constitutes an Assumed Liability, (iv) any Assumed Liability or any liability,
expense or obligation of the Business arising after the Closing Date, (v) any
use of the Name by Buyer or IHS not authorized by this Agreement and (vi) any
and all actions, suits, proceedings, demands assessments, judgments, settlements
(to the extent approved by Buyer, such approval not to be unreasonably withheld,
delayed or conditioned) costs and legal and other expenses incident to any of
the foregoing.

                  (b) Seller and Parent shall take all reasonable steps to
mitigate any Loss to the extent the same would have been required by applicable
law if the rights of Seller and Parent to compensation for damages arose under
law rather than by reason of contractual rights..

            6.3 Losses Net of Insurance, Etc. The amount of any Loss for which
indemnification is provided under this Article VI shall be net of (i) in the
case of Section 6.1, any reserves established on the Closing Balance Sheet of
the Seller, to the extent covering such Loss, (ii) any net insurance proceeds
actually collected by the indemnified party covering such loss and (iii) an
amount equal to the present value of the net Tax benefit, if any, attributable
to such Loss and used by the indemnified party, taking into account the receipt
of such recovery; it being understood that each party will use such Tax benefits
as promptly as reasonably practicable. If the amount to be netted hereunder from
any payment required under Sections 6.1 or 6.2 is determined after payment by
the indemnifying party of any amount otherwise required to be paid to an
indemnified party pursuant to this Article VI, the indemnified party shall repay
to the indemnifying party, promptly after such determination, any amount that
the indemnifying party would not have had to pay pursuant to this Article VI had
such determination been made at the time of such payment.

            6.4 Termination of Indemnification. The obligations to indemnify and
hold harmless a party hereto, (i) pursuant to Sections 6.1(a)(i) and 6.2(a)(i),
shall terminate when the applicable representation or warranty terminates
pursuant to Section 8.3, and (ii) pursuant to the other clauses of Sections 6.1
and 6.2, shall not terminate; provided; however, that as to clauses (i) and (ii)
above such obligations to indemnify and hold harmless shall not terminate with
respect to any item as to which the person to be indemnified (or the related
party thereto) shall have, before the expiration of the applicable period,
previously made a claim by delivering a notice (stating in reasonable detail the
basis of such claim) to the party providing the indemnification.

            6.5 Procedures Relating to Indemnification under Sections 6.1 and
6.2. (a) A party seeking indemnification pursuant to Sections 6.1 and 6.2 (an
"Indemnified Party") shall give prompt notice to the party from whom such
indemnification is sought (the "Indemnifying Party") of the assertion of any
claim or assessment, or the commencement of any action, suit, audit or
proceeding, by a third party in respect of which indemnity may be sought
hereunder (a "Third Party Claim") and will give the Indemnifying Party such
information with respect thereto as the Indemnifying Party may reasonably
request, but no failure to give such notice shall relieve the Indemnifying Party
of any liability hereunder (except to the extent the Indemnifying Party has
suffered actual prejudice thereby). The Indemnifying Party (which, in the case
of Seller or Parent, must include both such parties) shall have the right,
exercisable by written notice (the "Notice") to the Indemnified Party (which
notice shall state that the Indemnifying Party expressly agrees that as between
the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall
be solely obligated to satisfy and discharge the Third Party Claim) within
fourteen (14) days of receipt of notice from the Indemnified Party of the
commencement of or assertion of any Third Party Claim, to assume the defense of
such Third Party Claim, using counsel selected by the Indemnifying Party and
reasonably acceptable to the Indemnified Party; provided, that the Indemnifying
Party shall not have the right to assume a Third Party Claim if (i) the named
parties to any such action (including any impleaded parties) include both the
Indemnified Party and the Indemnifying Party and (ii) the Indemnified Party
shall have been advised by counsel in writing that under applicable standards of
professional responsibility, a conflict will arise in the event both the
Indemnified Party and the Indemnifying Party are represented by the same counsel
with respect to the Third Party Claim, in which case such Indemnified Party
shall have the right to participate in the defense of such Third Party Claim and
all Losses in connection therewith shall be reimbursed by the Indemnifying
Party. In addition, if the Indemnifying Party fails to give the Indemnified
Party the Notice complying with the provisions stated above within the stated
time period, the Indemnified Party shall have the right to assume control of the
defense of the Third Party Claim and all Losses in connection therewith shall be
reimbursed by the Indemnifying Party upon demand of the Indemnified Party.

            (b) If at any time after the Indemnifying Party assumes the defense
of a Third Party Claim, any of the conditions set forth in clauses (i) or (ii)
of subsection (a) above come

into existence the Indemnified Party shall have the same rights as set forth
above as if the Indemnifying Party never assumed the defense of such claim.

            (c) The Indemnifying Party or the Indemnified Party, as the case may
be, shall in any event have the right to participate, at its own expense, in the
defense of any Third Party Claim which the other is defending.

            (d) The Indemnifying Party, if it shall have assumed the defense of
any Third Party Claim in accordance with the terms hereof, shall have the right,
upon thirty (30) days prior written notice to the Indemnified Party, to consent
to the entry of judgment with respect to, or otherwise settle such Third Party
Claim unless (i) the Third Party Claim involves equitable or other non-monetary
damages or (ii) in the reasonable judgment of the Indemnified Party such
settlement would have a continuing material adverse effect on the Indemnified
Party's business (including any material impairment of its relationships with
customers and suppliers), in which case such settlement only may be made with
the written consent of the Indemnified Party, which consent shall not be
unreasonably withheld. Seller shall keep Buyer appraised of any material
negotiations between Seller and the U.S. Department of Labor, or any material
occurrences with respect to the same (to the extent within the knowledge of
Seller or the Parent), and will not enter into a settlement of such matters
without Buyer's consent, such consent not to be unreasonably withheld or
delayed.

            (e) Whether or not the Indemnifying Party chooses to defend or
prosecute any claim involving a third party, all the parties hereto shall
cooperate in the defense or prosecution thereof and shall furnish such records,
information and testimony, and attend such conferences, discovery proceedings,
hearings, trials and appeals as may be reasonably requested in connection
therewith.

cost or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Lender to fund the Advance to be made
by such Lender as part of such Borrowing when such Advance, as a result of such

an Appropriate Lender prior to the date of any Borrowing under a Facility under

the Administrative Agent such Lender's ratable portion of such Borrowing, the
Administrative Agent may assume that such Lender has made such portion available
to the Administrative Agent on the date of such Borrowing in accordance with
subsection (a) or (b) of this Section 2.02 and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Lender shall not have so
made such ratable portion available to the Administrative Agent, such Lender and
the Borrower severally agree to repay or pay to the Administrative Agent
forthwith on demand such corresponding amount and to pay interest thereon, for
each day from the date such amount is made available to the Borrower until the
date such amount is repaid or paid to the Administrative Agent, at (i) in the
case of the Borrower, the interest rate applicable at such time under Section
2.07 to Advances comprising such Borrowing and (ii) in the case of such Lender,
the Federal Funds Rate. If such Lender shall pay to the Administrative Agent
such corresponding amount, such amount so paid in respect of principal shall
constitute such Lender's Advance as part of such Borrowing for all purposes.

            (e) The failure of any Lender to make the Advance to be made by it
as part of any Borrowing shall not relieve any other Lender of its obligation,
if any, hereunder to make its Advance on the date of such Borrowing, but no
Lender shall be responsible for the failure of any other Lender to make the
Advance to be made by such other Lender on the date of any Borrowing.

            SECTION 2.03. Issuance of and Drawings and Reimbursement Under
Letters of Credit. (a) Request for Issuance. Each Letter of Credit shall be
issued upon notice, given not later than 11:00 A.M. (New York City time) on the
third Business Day prior to the date of the proposed issuance of such Letter of
Credit, by the Borrower to the Issuing Bank, which shall give to the
Administrative Agent prompt notice thereof by telex or telecopier. Each such
notice of issuance of a Letter of Credit (a "Notice of Issuance") shall be by
telephone, confirmed immediately in writing, or telex or telecopier, specifying
therein the requested (A) date of such issuance (which shall be a Business Day),
(B) Available Amount of such Letter of Credit, (C) expiration date of such
Letter of Credit, (D) name and address of the beneficiary of such Letter of
Credit and (E) form of such Letter of Credit, and shall

<PAGE>

                                       41


be accompanied by such application and agreement for letter of credit as the
Issuing Bank may specify to the Borrower for use in connection with such
requested Letter of Credit (a "Letter of Credit Agreement"). If (x) the
requested form of such Letter of Credit is acceptable to the Issuing Bank in its
sole discretion and (y) it has not received notice of objection to such issuance
from Lenders holding at least 66-2/3% of the Working Capital Commitments, the
Issuing Bank will, upon fulfillment of the applicable conditions set forth in
Article III, make such Letter of Credit available to the Borrower at its office
referred to in Section 9.02 or as otherwise agreed with the Borrower in
connection with such issuance. In the event and to the extent that the
provisions of any Letter of Credit Agreement shall conflict with this Agreement,
the provisions of this Agreement shall govern.

            (b) Letter of Credit Reports. The Issuing Bank shall furnish (A) to
the Administrative Agent on the first Business Day of each week a written report
summarizing issuance and expiration dates of Letters of Credit issued during the
previous week and drawings during such week under all Letters of Credit, (B) to
each Working Capital Lender on the first Business Day of each calendar quarter a
written report summarizing issuance and expiration dates of Letters of Credit
issued during the preceding calendar quarter and drawings during such month
under all Letters of Credit and (C) to the Administrative Agent and each Working
Capital Lender on the first Business Day of each calendar quarter a written
report setting forth the average daily aggregate Available Amount during the
preceding calendar quarter of all Letters of Credit.

            (c) Drawing and Reimbursement. The payment by the Issuing Bank of a
draft drawn under any Letter of Credit shall constitute for all purposes of this
Agreement the making by the Issuing Bank of a Letter of Credit Advance, which
shall be a Base Rate Advance, in the amount of such draft. In the event of any
drawing under a Letter of Credit, the Issuing Bank shall promptly notify the
Administrative Agent, and the Administrative Agent shall promptly notify each
Working Capital Lender and the Borrower and each Working Capital Lender shall
purchase from the Issuing Bank, and the Issuing Bank shall sell and assign to
each such Working Capital Lender, such Lender's Pro Rata Share of such
outstanding Letter of Credit Advance as of the date of such purchase, by making
available for the account of its Applicable Lending Office to the Administrative
Agent for the account of the Issuing Bank, by deposit to the Administrative
Agent's Account, in same day funds, an amount equal to the portion of the
outstanding principal amount of such Letter of Credit Advance to be purchased by
such Lender. Promptly after receipt thereof, the Administrative Agent shall
transfer such funds to the Issuing Bank. The Borrower hereby agrees to each such
sale and assignment. Each Working Capital Lender agrees to purchase its Pro Rata
Share of an outstanding Letter of Credit Advance on (i) the Business Day on
which notice of the drawing under the related Letter of Credit is given by the
Issuing Bank, provided such notice is given not later than 1:00 P.M. (New York
City time) on such Business Day or (ii) the first Business Day next succeeding
such demand if such notice is given after such time. Upon any such assignment by
the Issuing Bank to any other Working Capital Lender

<PAGE>

                                       42


of a portion of a Letter of Credit Advance, the Issuing Bank represents and
warrants to such other Lender that the Issuing Bank is the legal and beneficial
owner of such interest being assigned by it, free and clear of any liens, but
makes no other representation or warranty and assumes no responsibility with
respect to such Letter of Credit Advance, the Loan Documents or any Loan Party.
If and to the extent that any Working Capital Lender shall not have so made the
amount of such Letter of Credit Advance available to the Administrative Agent,
such Working Capital Lender agrees to pay to the Administrative Agent forthwith
on demand such amount together with interest thereon, for each day from the date
of demand by the Issuing Bank until the date such amount is paid to the
Administrative Agent, at the Federal Funds Rate for its account or the account
of the Issuing Bank, as applicable. If such Lender shall pay to the
Administrative Agent such amount for the account of the Issuing Bank on any
Business Day, such amount so paid in respect of principal shall constitute a
Letter of Credit Advance made by such Lender on such Business Day for purposes
of this Agreement, and the outstanding principal amount of the Letter of Credit
Advance made by the Issuing Bank shall be reduced by such amount on such
Business Day.

            (d) Failure to Make Letter of Credit Advances. The failure of any
Lender to make the Letter of Credit Advance to be made by it on the date
specified in Section 2.03(c) shall not relieve any other Lender of its
obligation hereunder to make its Letter of Credit Advance on such date, but no
Lender shall be responsible for the failure of any other Lender to make the
Letter of Credit Advance to be made by such other Lender on such date.

            SECTION 2.04. Repayment of Advances. (a) Term Advances. The Borrower
shall repay to the Administrative Agent for the ratable account of the Term A
Lenders and Term B Lenders the aggregate outstanding principal amount of the
Term A Advances and Term B Advances, respectively, on the following dates in the
amounts indicated (which amounts shall be reduced as a result of the application
of prepayments in accordance with the order of priority set forth in Section
2.06):

From and after the Conversion Date, each such prepayment of any Advances shall

any of its Subsidiaries in the period immediately following (x) with respect to
the first such prepayment, the Initial Extension of Credit and (y) with respect
to any prepayment after the first such prepayment, the most recent such

Collateral on such Business Day (as determined based on the most recent
Borrowing Base Certificate delivered to the Lender Parties hereunder).

            (iv) The Borrower shall, on each Business Day, pay to the

are required to be applied pursuant to Section 2.06(b)(vi).

            (vi) Prepayments of the Working Capital Facility shall be first
applied to prepay Letter of Credit Advances then outstanding until such Letter
of Credit Advances are paid in full, second applied to prepay Working Capital
Advances then outstanding comprising part of the same Borrowings until such
Working Capital Advances are paid in full and third deposited in the L/C Cash
Collateral Account to cash collateralize 100% of the Available Amount of the
Letters of Credit then outstanding; and, in the case of prepayments of the
Working Capital Facility required pursuant to clause (i) or (ii) above, the
amount remaining (if any) after the prepayment in full of the Working Capital
Advances then outstanding and the 100% cash collateralization of the aggregate
Available Amount of Letters of Credit then outstanding (the sum of such

remaining amount being referred to herein as the "Reduction Amount") may be
retained by the Borrower and the Working Capital Facility shall be permanently
reduced as set forth in Section 2.05(b)(iii). Upon the drawing of any Letter of
Credit for which funds are on deposit in the L/C Cash Collateral Account, such
funds shall be applied to reimburse the Issuing Bank or Working Capital Lenders,
as applicable.

            (vii) Prior to the Conversion Date, the Borrower shall, on the date

prepayments required by Section 2.06(b)(vii), the Acquisition Facility shall be
permanently reduced as set forth in Section 2.05(b)(v).

            (ix) On the Conversion Date, the Borrower shall prepay an aggregate
principal amount of the Advances comprising part of the same Borrowings equal to
the amount on deposit in the Asset Sale Blocked Account plus the Asset Sale
Release Amount. Each such prepayment shall be applied as follows:

            first, to the Acquisition Facility,

            second, to the extent no Acquisition Advances remain outstanding,
      ratably to the Term A Facility and the Term B Facility, in each case
      ratably to the principal installments thereof, and

            third, to the extent no Term Advances or Acquisition Advances remain
      outstanding, permanently to reduce the Working Capital Facility as set
      forth in clause (vi) above.

                                       51


            (xi) The Borrower shall, on each Business Day, prepay an aggregate
principal amount of the Advances comprising part of the same Borrowings equal to
the amount by which the amount on deposit in the Asset Sale Blocked Account
exceeds the aggregate amount of Subordinated Notes outstanding. Each such
prepayment shall be applied as follows:

            first, to the Acquisition Facility,

            second, to the extent no Acquisition Advances remain outstanding,
      ratably to the Term A Facility and the Term B Facility, in each case
      ratably to the principal installments thereof, and

            third, to the extent no Term Advances or Acquisition Advances remain
      outstanding, permanently to reduce the Working Capital Facility as set
      forth in clause (vi) above.

            (c) Term B Opt-Out. With respect to any prepayment of the Term B
Advances, the Administrative Agent shall ratably pay the Term B Lenders as
required under Section 2.06(a) or (b), unless, with respect to any prepayment
from time to time of the Term B Advances, the Administrative Agent shall have
received written notice from any Term B Lender not later than three Business
Days prior to such prepayment, that such Term B Lender elects not to receive any
prepayments under this Section 2.06 (a "Term B Opt-Out Lender"), which election
shall remain in effect with respect to any subsequent prepayment until the
Administrative Agent shall receive a subsequent written notice from such Term B
Opt-Out Lender cancelling such earlier notice. Any such prepayments which would
have been remitted to a Term B Opt-Out Lender but for its election to not
receive such prepayments, shall be paid ratably to the remaining Lenders as
provided in Sections 2.06(a) and (b); provided, however, that Term B Lenders, on
any date on which the Term A Facility is repaid in full and no Acquisition
Advances are outstanding, shall not be entitled to elect not to receive any
further prepayments.

            SECTION 2.07. Interest. (a) Scheduled Interest. The Borrower shall

      Base Rate Advance, a rate per annum equal at all times to the sum of (A)
      the Base Rate in effect from time to time plus (B) the Applicable Margin
      in effect from time to time, payable in arrears quarterly on the last
      Business Day of each March, June, September and December during such
      periods, on the date of any prepayment thereof to the

      extent required under Section 2.06(b) and on the Final Maturity Date,
      commencing December 31, 1996.

            (ii) Eurodollar Rate Advances. During such periods as such Advance
      is a Eurodollar Rate Advance, a rate per annum equal at all times during
      each Interest Period for such Advance to the sum of (A) the Eurodollar
      Rate for such Interest Period for such Advance plus (B) the Applicable
      Margin in effect on the first day of such Interest Period, payable in
      arrears on the last day of such Interest Period and, if such Interest
      Period has a duration of more than three months, on each day that occurs
      during such Interest Period every three months from the first day of such
      Interest Period and on the date such Eurodollar Rate Advance shall be
      Converted or paid in full.

            (b) Default Interest. Upon the occurrence and during the continuance
of any Event of Default, the Administrative Agent may, and upon the request of
the Required Lenders shall, require that the Borrower pay interest on (i) the
unpaid principal amount of each Advance owing to each Lender, payable in arrears
on the dates referred to in clause (a)(i) or (a)(ii) above and on demand, at a
rate per annum equal at all times to 2% per annum above the rate per annum
required to be paid on such Advance pursuant to clause (a)(i) or (a)(ii) above
and (ii) to the fullest extent permitted by law, the amount of any interest, fee
or other amount payable hereunder that is not paid when due, from the date such
amount shall be due until such amount shall be paid in full, payable in arrears
on the date such amount shall be paid in full and on demand, at a rate per annum
equal at all times to 2% per annum above the rate per annum required to be paid,
in the case of interest, on the Type of Advance on which such interest has
accrued pursuant to clause (a)(i) or (a)(ii) above, and, in all other cases, on
Base Rate Advances pursuant to clause (a)(i) above.

            SECTION 2.08. Fees. (a) Commitment Fee. The Borrower shall pay to
the Administrative Agent for the account of the Lenders a commitment fee on the
average daily portion of each Appropriate Lender's Unused Acquisition Commitment
(prior to the Conversion Date) and on the average daily Unused Working Capital
Commitment of each Appropriate Lender, from the date hereof in the case of each
Initial Lender and from the effective date specified in the Assignment and
Acceptance pursuant to which it became a Lender in the case of each other Lender
until the Termination Date, payable in arrears quarterly on the last Business
Day of each March, June, September and December, commencing December 31, 1996,
and, with respect to Unused Acquisition Commitments, on the Conversion Date or,
with respect to Unused Working Capital Commitments, on the Termination Date, at
the rate of half of 1% per annum on the average daily portion of each
Appropriate Lender's Unused Acquisition Commitment and on the average daily

<PAGE>

                                       53


such time shall not be payable by the Borrower so long as such Lender shall be a
Defaulting Lender except to the extent that such commitment fee shall otherwise
have been due and payable by the Borrower prior to such time; and provided
further that no commitment fee shall accrue on any of the Commitments of a
Defaulting Lender so long as such Lender shall be a Defaulting Lender.

            (b) Letter of Credit Fees, Etc. (i) The Borrower shall pay to the
Administrative Agent for the account of each Working Capital Lender a
commission, payable in arrears quarterly on the last Business Day of each March,

Available Amount during such quarter of (A) all Standby Letters of Credit
outstanding from time to time and (B) all Trade Letters of Credit then
outstanding, in each case at the rate per annum equal to the Applicable Margin
for Working Capital Advances which are Eurodollar Rate Advances in effect from
time to time.

            (ii) The Borrower shall pay to the Issuing Bank, for its own
account, such commissions, issuance fees, fronting fees, transfer fees and other
fees and charges in connection with the issuance or administration of each
Letter of Credit as the Borrower and the Issuing Bank shall agree.

            (c) Agents' Fees. The Borrower shall pay to each of the Agents for
its own account such fees as may from time to time be agreed between the
Borrower and such Agent.

            SECTION 2.09. Conversion of Advances. (a) Optional. The Borrower may
on any Business Day, upon notice given to the Administrative Agent not later
than 11:00 A.M. (New York City time) on the third Business Day prior to the date
of the proposed Conversion and subject to the provisions of Sections 2.07 and
2.10, Convert all or any portion of the Advances of one Type comprising the same
Borrowing into Advances of the other Type; provided, however, that (w) if any
Conversion of Eurodollar Rate Advances into Base Rate Advances is made other
than on the last day of an Interest Period for such Eurodollar Rate Advances,
the Borrower shall also pay any amounts owing pursuant to Section 9.04(c), (x)
any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in
an amount not less than the minimum amount specified in Section 2.02(b), (y) no
Conversion of any Advances shall result in more separate Borrowings than
permitted under Section 2.02(b), and (z) each Conversion of Advances comprising
part of the same Borrowing under any Facility shall be made ratably among the
Appropriate Lenders in accordance with their Commitments under such Facility.
Each such notice of Conversion shall, within the restrictions specified above,
specify (i) the date of such Conversion, (ii) the Advances to be Converted and
(iii) if such Conversion is into Eurodollar Rate Advances, the duration of the
initial Interest Period for such Advances. Each notice of Conversion shall be
irrevocable and binding on the Borrower.

<PAGE>

                                       54


            (b) Mandatory. (i) On the date on which the aggregate unpaid
principal amount of Eurodollar Rate Advances comprising any Borrowing shall be
reduced, by payment or prepayment or otherwise, to less than $1,000,000, such
Advances shall automatically Convert into Base Rate Advances.

            (ii) If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "Interest Period" in Section 1.01, the
Administrative Agent will forthwith so notify the Borrower and the Appropriate
Lenders, whereupon each such Eurodollar Rate Advance will automatically, on the
last day of the then existing Interest Period therefor, Convert into a Base Rate
Advance.

            (iii) Upon the occurrence and during the continuance of any Event of
Default, (x) each Eurodollar Rate Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance and
(y) the obligation of the Lenders to make, or to Convert Advances into,
Eurodollar Rate Advances shall be suspended.

            SECTION 2.10. Increased Costs, Etc. (a) If, due to either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender Party of agreeing to make
or of making, funding or maintaining Eurodollar Rate Advances or of agreeing to
issue or of issuing or maintaining Letters of Credit or of agreeing to make or
of making or maintaining Letter of Credit Advances, then the Borrower shall from
time to time, upon demand by such Lender Party (with a copy of such demand to
the Administrative Agent), pay to the Administrative Agent for the account of
such Lender Party additional amounts sufficient to compensate such Lender Party
for such increased cost. A certificate as to the amount of such increased cost,
submitted to the Borrower by such Lender Party, shall be conclusive and binding
for all purposes, absent manifest error.

            (b) If any Lender Party determines that compliance with any law or
regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender Party or any corporation controlling such Lender Party and that the
amount of such capital is increased by or based upon the existence of such
Lender Party's commitment to lend or to issue Letters of Credit hereunder and
other commitments of such type or the issuance or maintenance of the Letters of
Credit (or similar contingent obligations), then, upon demand by such Lender
Party (with a copy of such demand to the Administrative Agent), the Borrower
shall pay to the Administrative Agent for the account of such Lender Party, from
time to time as specified by such Lender Party, additional amounts sufficient to
compensate such Lender Party in the light of such

<PAGE>

                                       55


circumstances, to the extent that such Lender Party reasonably determines such
increase in capital to be allocable to the existence of such Lender Party's
commitment to lend or to issue Letters of Credit hereunder or to the issuance or
maintenance of any Letters of Credit. A certificate as to such amounts submitted
to the Borrower by such Lender Party shall be conclusive and binding for all
purposes, absent manifest error. Each Lender will determine the amount of any
additional compensation requested under this Section 2.10(b) on a basis
consistent with that on which it requests additional compensation from other
similar borrowers with whom it has an agreement similar to the agreement
contained in this Section 2.10(b).

            (c) If, with respect to any Eurodollar Rate Advances under any
Facility, Lenders owed more than 50% of the then aggregate unpaid principal
amount thereof notify the Administrative Agent that the Eurodollar Rate for any
Interest Period for such Advances will not adequately reflect the cost to such
Lenders of making, funding or maintaining their Eurodollar Rate Advances for
such Interest Period, the Administrative Agent shall forthwith so notify the
Borrower and the Appropriate Lenders, whereupon (i) each such Eurodollar Rate
Advance under any Facility will automatically, on the last day of the then
existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the
obligation of the Appropriate Lenders to make, or to Convert Advances into,
Eurodollar Rate Advances shall be suspended until the Administrative Agent shall
notify the Borrower that such Lenders have determined that the circumstances
causing such suspension no longer exist.

            (d) Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other governmental
authority shall assert that it is unlawful, for any Lender or its Eurodollar
Lending Office to perform its obligations hereunder to make Eurodollar Rate
Advances or to continue to fund or maintain Eurodollar Rate Advances hereunder,
then, on notice thereof and demand therefor by such Lender to the Borrower
through the Administrative Agent, (i) each Eurodollar Rate Advance under each
Facility under which such Lender has a Commitment will automatically, upon such
demand, Convert into a Base Rate Advance and (ii) the obligation of the
Appropriate Lenders to make, or to Convert Advances into, Eurodollar Rate
Advances shall be suspended until the Administrative Agent shall notify the
Borrower that such Lender has determined that the circumstances causing such
suspension no longer exist.

            SECTION 2.11. Payments and Computations. (a) The Borrower shall make
each payment hereunder and under the Notes, irrespective of any right of
counterclaim or set-off (except as otherwise provided in Section 2.15), not
later than 11:00 A.M. (New York City time) on the day when due in U.S. dollars
to the Administrative Agent at the Administrative Agent's Account in same day
funds. The Administrative Agent will promptly thereafter cause like funds to be
distributed (i) if such payment by the Borrower is in respect of principal,
interest, commitment fees or any other Obligation then payable hereunder and

<PAGE>

                                       56


under the Notes to more than one Lender Party, to such Lender Parties for the
account of their respective Applicable Lending Offices ratably in accordance
with the amounts of such respective Obligations then payable to such Lender
Parties and (ii) if such payment by the Borrower is in respect of any Obligation
then payable hereunder to one Lender Party, to such Lender Party for the account
of its Applicable Lending Office, in each case to be applied in accordance with
the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance
and recording of the information contained therein in the Register pursuant to
Section 9.07(d), from and after the effective date of such Assignment and
Acceptance, the Administrative Agent shall make all payments hereunder and under
the Notes in respect of the interest assigned thereby to the Lender Party
assignee thereunder, and the parties to such Assignment and Acceptance shall
make all appropriate adjustments in such payments for periods prior to such
effective date directly between themselves.

            (b) If the Administrative Agent receives funds for application to
the Obligations under the Loan Documents under circumstances for which the Loan
Documents do not specify the Advances or the Facility to which, or the manner in
which, such funds are to be applied, the Administrative Agent shall elect to
distribute such funds to each Lender Party ratably in accordance with such
Lender Party's proportionate share of the principal amount of all outstanding
Advances and the Available Amount of all Letters of Credit then outstanding, in
repayment or prepayment of such of the outstanding Advances or other Obligations
owed to such Lender Party, and for application to such principal installments,
as the Administrative Agent shall direct.

            (c) After an Event of Default, the Borrower hereby authorizes each
Lender Party, if and to the extent payment owed to such Lender Party is not made
when due hereunder or, in the case of a Lender, under the Note held by such
Lender, to charge from time to time against any or all of the Borrower's
accounts with such Lender Party any amount so due.

            (d) All computations of interest, fees and Letter of Credit
commissions shall be made by the Administrative Agent on the basis of a year of
360 days, in each case for the actual number of days (including the first day
but excluding the last day) occurring in the period for which such interest,
fees or commissions are payable. Each determination by the Administrative Agent
of an interest rate, fee or commission hereunder shall be conclusive and binding
for all purposes, absent manifest error.

            (e) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or commitment fee, as
the case may be; provided, however, that, if such extension would cause such
payment to be made in the next following calendar month, such payment shall be
made on the next preceding Business Day.

<PAGE>

                                       57


            (f) Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to any Lender Party
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each such Lender Party
on such due date an amount equal to the amount then due such Lender Party. If
and to the extent the Borrower shall not have so made such payment in full to
the Administrative Agent, each such Lender Party shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Lender
Party together with interest thereon, for each day from the date such amount is
distributed to such Lender Party until the date such Lender Party repays such
amount to the Administrative Agent, at the Federal Funds Rate.

            SECTION 2.12. Taxes. (a) Any and all payments by the Borrower
hereunder or under the Notes shall be made, in accordance with Section 2.11,
free and clear of and without deduction for any and all present or future taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender Party and each Agent,
taxes imposed on its overall net income by the United States and franchise taxes
and net income taxes that are imposed on such Lender Party or such Agent in lieu
of net income taxes by the state or foreign jurisdiction under the laws of which
such Lender Party or such Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Lender Party, taxes
imposed on its overall net income and franchise taxes imposed on such Lender
Party in lieu of net income taxes by the state or foreign jurisdiction of such
Lender Party's Applicable Lending Office or any political subdivision thereof
(all such non-excluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall
be required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to any Lender Party or any Agent, (i) the sum
payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.12) such Lender Party or such Agent (as the case may be) receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall
pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

            (b) In addition, the Borrower shall pay any present or future stamp,
documentary, excise, property or similar taxes, charges or levies that arise
from any payment made hereunder or under the Notes or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or the
Notes (hereinafter referred to as "Other Taxes").

<PAGE>

                                       58


            (c) The Borrower shall indemnify each Lender Party and each Agent
for and hold it harmless against the full amount of Taxes and Other Taxes, and
for the full amount of taxes of any kind imposed by any jurisdiction on amounts
payable under this Section 2.12, paid by such Lender Party or such Agent (as the
case may be) and any liability (including penalties, additions to tax, interest
and expenses) arising therefrom or with respect thereto. This indemnification
shall be made within 30 days from the date such Lender Party or such Agent (as
the case may be) makes written demand therefor.

            (d) Within 30 days after the date of any payment of Taxes, the
Borrower shall furnish to the Administrative Agent, at its address referred to
in Section 9.02, the original or a certified copy of a receipt evidencing such
payment. In the case of any payment hereunder or under the Notes by or on behalf
of the Borrower through an account or branch outside the United States or on
behalf of the Borrower by a payor that is not a United States person, if the
Borrower determines that no Taxes are payable in respect thereof, the Borrower
shall furnish, or shall cause such payor to furnish, to the Administrative
Agent, at such address, an opinion of counsel acceptable to the Administrative
Agent stating that such payment is exempt from Taxes. For purposes of this
subsection (d) and subsection (e), the terms "United States" and "United States
person" shall have the meanings specified in Section 7701 of the Internal
Revenue Code.

            (e) Each Lender Party organized under the laws of a jurisdiction
outside the United States shall, on or prior to the date of its execution and
delivery of this Agreement in the case of each Initial Lender or Initial Issuing
Bank, as the case may be, and on the date of the Assignment and Acceptance
pursuant to which it becomes a Lender Party in the case of each other Lender
Party, and from time to time thereafter if requested in writing by the Borrower
or the Administrative Agent (but only so long thereafter as such Lender Party
remains lawfully able to do so), provide the Administrative Agent and the
Borrower with Internal Revenue Service form 1001 or 4224, or in the case of a
Lender Party that is claiming exemption from United States withholding tax under
Section 871(h) or 881(c) of the Internal Revenue Code with respect to payments
of "portfolio interest" two accurate and complete signed original Forms W-8 and,
if such Lender Party delivers forms W-8, two signed certificates certifying that
such Lender Party is not (i) a "bank" for purposes of Section 881(c) of the
Internal Revenue Code, (ii) is not a 10% shareholder (within the meaning of
Section 871(h)(3)(B) of the Internal Revenue Code) of the Borrower and (iii) is
not a controlled foreign corporation related to the Borrower (within the meaning
of Section 864(d)(4) of the Internal Revenue Code), as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Lender Party is exempt from or is entitled to a reduced rate of United States
withholding tax on payments under this Agreement or the Notes. If the form
provided by a Lender Party at the time such Lender Party first becomes a party
to this Agreement indicates a United States interest withholding tax rate in
excess of zero, withholding tax at such rate shall be considered excluded from
Taxes unless and until such Lender Party provides the appropriate form
certifying that a lesser rate applies,

<PAGE>

                                       59


whereupon withholding tax at such lesser rate only shall be considered excluded
from Taxes for periods governed by such form; provided, however, that, if at the
date of the Assignment and Acceptance pursuant to which a Lender Party becomes a
party to this Agreement, the Lender Party assignor was entitled to payments
under subsection (a) in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term Taxes shall include
(in addition to withholding taxes that may be imposed in the future or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Lender Party assignee on such date. If any form
or document referred to above in this subsection (e) requires the disclosure of
information, other than information necessary to compute the tax payable and
information required on the date hereof by Internal Revenue Service form 1001 or
4224, that the Lender Party reasonably considers to be confidential, the Lender
Party shall give notice thereof to the Borrower and shall not be obligated to
include in such form or document such confidential information.

            (f) For any period with respect to which a Lender Party has failed
to provide the Borrower with the appropriate form described in subsection (e)
above (other than if such failure is due to a change in law occurring after the
date on which a form originally was required to be provided or if such form
otherwise is not required under subsection (e) above), such Lender Party shall
not be entitled to indemnification under subsection (a) or (c) with respect to
Taxes imposed by the United States; provided, however, that should a Lender
Party become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Lender Party shall
reasonably request to assist such Lender Party to recover such Taxes.

            SECTION 2.13. Sharing of Payments, Etc. If any Lender Party shall
obtain at any time any payment (whether voluntary, involuntary, through the
exercise of any right of set-off, or otherwise) (a) on account of Obligations
due and payable to such Lender Party hereunder and under the Notes at such time
in excess of its ratable share (according to the proportion of (i) the amount of
such Obligations due and payable to such Lender Party at such time to (ii) the
aggregate amount of the Obligations due and payable to all Lender Parties
hereunder and under the Notes at such time) of payments on account of the
Obligations due and payable to all Lender Parties hereunder and under the Notes
at such time obtained by all the Lender Parties at such time or (b) on account
of Obligations owing (but not due and payable) to such Lender Party hereunder
and under the Notes at such time in excess of its ratable share (according to
the proportion of (i) the amount of such Obligations owing to such Lender Party
at such time to (ii) the aggregate amount of the Obligations owing (but not due
and payable) to all Lender Parties hereunder and under the Notes at such time)
of payments on account of the Obligations owing (but not due and payable) to all
Lender Parties hereunder and under the Notes at such time obtained by all of the
Lender Parties at such time, such Lender Party shall forthwith purchase from the
other Lender Parties such participations in the Obligations due and payable or
owing to them, as the case may be, as shall be necessary to cause such
purchasing Lender Party to share the excess

<PAGE>

                                       60


payment ratably with each of them; provided, however, that if all or any portion
of such excess payment is thereafter recovered from such purchasing Lender
Party, such purchase from each other Lender Party shall be rescinded and such
other Lender Party shall repay to the purchasing Lender Party the purchase price
to the extent of such Lender Party's ratable share (according to the proportion
of (i) the purchase price paid to such Lender Party to (ii) the aggregate
purchase price paid to all Lender Parties) of such recovery together with an
amount equal to such Lender Party's ratable share (according to the proportion
of (i) the amount of such other Lender Party's required repayment to (ii) the
total amount so recovered from the purchasing Lender Party) of any interest or
other amount paid or payable by the purchasing Lender Party in respect of the
total amount so recovered. The Borrower agrees that any Lender Party so
purchasing a participation from another Lender Party pursuant to this Section
2.13 may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of set-off) with respect to such participation as
fully as if such Lender Party were the direct creditor of the Borrower in the
amount of such participation.

            SECTION 2.14. Use of Proceeds. The proceeds of the Advances and
issuances of Letters of Credit shall be available (and the Borrower agrees that
it shall use such proceeds and Letters of Credit) solely as follows:

            (a) from Term Advances, to refinance, in part, the Refinancing Debt
      and to pay transaction fees and expenses in connection therewith and with
      the financing contemplated by the Loan Documents;

            (b) from Acquisition Advances:

                  (i) to refinance, in part, the Refinancing Debt, and to pay
            transaction fees and expenses in connection therewith;

                  (ii) on terms permitted by Section 5.02(k)(i)(y)(B); and

                  (iii) from and after the Asset Sale Threshold Date and subject
            to the Acquisition Facility Sublimit (x) to pay dividends and
            repurchase shares of the common stock of MEDIQ to the extent
            permitted by Section 5.02(g)(i) and (y), if no repurchase of shares
            pursuant to Section 5.02(g)(i) has occurred, to make Investments
            permitted by Section 5.02(f)(i); and

            (c) from Working Capital Advances, to finance working capital
      requirements of the Borrower, to be deposited in the Asset Sale Blocked
      Account, to make payments required under Section 5.01(p) and for other
      general corporate purposes permitted by this Agreement; provided, however,
      that Working Capital Advances may not be used for the purposes for which
      Acquisition Advances may be

<PAGE>

                                      61


      used in accordance with Section 2.14(b) except, if any Investment pursuant
      to Section 5.02(f)(vi)(x) shall have been made, to the extent of the
      amount of such Investment.

            SECTION 2.15. Defaulting Lenders. (a) In the event that, at any one
time, (i) any Lender Party shall be a Defaulting Lender, (ii) such Defaulting
Lender shall owe a Defaulted Advance to the Borrower and (iii) the Borrower
shall be required to make any payment hereunder or under any other Loan Document
to or for the account of such Defaulting Lender, then the Borrower may, so long
as no Default shall occur or be continuing at such time and to the fullest
extent permitted by applicable law, set off and otherwise apply the Obligation
of the Borrower to make such payment to or for the account of such Defaulting
Lender against the obligation of such Defaulting Lender to make such Defaulted
Advance. In the event that, on any date, the Borrower shall so set off and
otherwise apply its obligation to make any such payment against the obligation
of such Defaulting Lender to make any such Defaulted Advance on or prior to such
date, the amount so set off and otherwise applied by the Borrower shall
constitute for all purposes of this Agreement and the other Loan Documents an
Advance by such Defaulting Lender made on the date under the Facility pursuant
to which such Defaulted Advance was originally required to have been made
pursuant to Section 2.01. Such Advance shall be a Base Rate Advance and shall be
considered, for all purposes of this Agreement, to comprise part of the
Borrowing in connection with which such Defaulted Advance was originally
required to have been made pursuant to Section 2.01, even if the other Advances
comprising such Borrowing shall be Eurodollar Rate Advances on the date such
Advance is deemed to be made pursuant to this subsection (a). The Borrower shall
notify the Administrative Agent at any time the Borrower exercises its right of
set-off pursuant to this subsection (a) and shall set forth in such notice (A)
the name of the Defaulting Lender and the Defaulted Advance required to be made
by such Defaulting Lender and (B) the amount set off and otherwise applied in
respect of such Defaulted Advance pursuant to this subsection (a). Any portion
of such payment otherwise required to be made by the Borrower to or for the
account of such Defaulting Lender which is paid by the Borrower, after giving
effect to the amount set off and otherwise applied by the Borrower pursuant to
this subsection (a), shall be applied by the Administrative Agent as specified
in subsection (b) or (c) of this Section 2.15.

            (b) In the event that, at any one time, (i) any Lender Party shall
be a Defaulting Lender, (ii) such Defaulting Lender shall owe a Defaulted Amount
to the Administrative Agent or any of the other Lender Parties and (iii) the
Borrower shall make any payment hereunder or under any other Loan Document to
the Administrative Agent for the account of such Defaulting Lender, then the
Administrative Agent may, on its behalf or on behalf of such other Lender
Parties and to the fullest extent permitted by applicable law, apply at such
time the amount so paid by the Borrower to or for the account of such Defaulting
Lender to the payment of each such Defaulted Amount to the extent required to
pay such Defaulted Amount. In the event that the Administrative Agent shall so
apply any such amount to the payment of any such Defaulted Amount on any date,
the amount so
<PAGE>

                                      62


applied by the Administrative Agent shall constitute for all purposes of this
Agreement and the other Loan Documents payment, to such extent, of such
Defaulted Amount on such date. Any such amount so applied by the Administrative
Agent shall be retained by the Administrative Agent or distributed by the
Administrative Agent to such other Lender Parties, ratably in accordance with
the respective portions of such Defaulted Amounts payable at such time to the
Administrative Agent and such other Lender Parties and, if the amount of such
payment made by the Borrower shall at such time be insufficient to pay all
Defaulted Amounts owing at such time to the Administrative Agent and the other
Lender Parties, in the following order of priority:

            (i) first, to the Administrative Agent for any Defaulted Amount then
      owing to the Administrative Agent; and

            (ii) second, to any other Lender Parties for any Defaulted Amounts
      then owing to such other Lender Parties, ratably in accordance with such
      respective Defaulted Amounts then owing to such other Lender Parties.

Any portion of such amount paid by the Borrower for the account of such
Defaulting Lender remaining, after giving effect to the amount applied by the
Administrative Agent pursuant to this subsection (b), shall be applied by the
Administrative Agent as specified in subsection (c) of this Section 2.15.

            (c) In the event that, at any one time, (i) any Lender Party shall
be a Defaulting Lender, (ii) such Defaulting Lender shall not owe a Defaulted
Advance or a Defaulted Amount and (iii) the Borrower, the Administrative Agent
or any other Lender Party shall be required to pay or distribute any amount
hereunder or under any other Loan Document to or for the account of such
Defaulting Lender, then the Borrower or such other Lender Party shall pay such
amount to the Administrative Agent to be held by the Administrative Agent, to
the fullest extent permitted by applicable law, in escrow or the Administrative
Agent shall, to the fullest extent permitted by applicable law, hold in escrow
such amount otherwise held by it. Any funds held by the Administrative Agent in
escrow under this subsection (c) shall be deposited by the Administrative Agent
in an account with BNP, in the name and under the control of the Administrative
Agent, but subject to the provisions of this subsection (c). The terms
applicable to such account, including the rate of interest payable with respect
to the credit balance of such account from time to time, shall be BNP's standard
terms applicable to escrow accounts maintained with it. Any interest credited to
such account from time to time shall be held by the Administrative Agent in
escrow under, and applied by the Administrative Agent from time to time in
accordance with the provisions of, this subsection (c). The Administrative Agent
shall, to the fullest extent permitted by applicable law, apply all funds so
held in escrow from time to time to the extent necessary to make any Advances
required to be made by such Defaulting Lender and to pay any amount payable by
such Defaulting Lender hereunder and under the other Loan
<PAGE>

                                      63


Documents to the Administrative Agent or any other Lender Party, as and when
such Advances or amounts are required to be made or paid and, if the amount so
held in escrow shall at any time be insufficient to make and pay all such
Advances and amounts required to be made or paid at such time, in the following
order of priority:

            (i) first, to the Administrative Agent for any amount then due and
      payable by such Defaulting Lender to the Administrative Agent hereunder;

            (ii) second, to any other Lender Parties for any amount then due and
      payable by such Defaulting Lender to such other Lender Parties hereunder,
      ratably in accordance with such respective amounts then due and payable to
      such other Lender Parties; and

            (iii) third, to the Borrower for any Advance then required to be
      made by such Defaulting Lender pursuant to a Commitment of such Defaulting
      Lender.

In the event that any Lender Party that is a Defaulting Lender shall, at any
time, cease to be a Defaulting Lender, any funds held by the Administrative
Agent in escrow at such time with respect to such Lender Party shall be
distributed by the Administrative Agent to such Lender Party and applied by such
Lender Party to the Obligations owing to such Lender Party at such time under
this Agreement and the other Loan Documents ratably in accordance with the
respective amounts of such Obligations outstanding at such time.

            (d) The rights and remedies against a Defaulting Lender under this
Section 2.15 are in addition to other rights and remedies that the Borrower may
have against such Defaulting Lender with respect to any Defaulted Advance and
that the Administrative Agent or any Lender Party may have against such
Defaulting Lender with respect to any Defaulted Amount.

            SECTION 2.16. Release of Funds from the Asset Sale Blocked Account.
So long as no Default shall have occurred and be continuing, the Administrative
Agent will, upon presentation of a Notice of Drawing by the Borrower to the
Administrative Agent substantially in the form of Exhibit F hereto, pay and
release to the Borrower or at its order and at the request of the Borrower, the
amount, if any, or any portion thereof, on deposit in the Asset Sale Blocked
Account, so long as the Borrower applies such amount (A) in the same manner and
on the same basis as is permitted for Acquisition Advances pursuant to Section
2.14(b), (B) to prepay the Working Capital Facility pursuant to Section 2.06(a)
or (C) or as required pursuant to Section 2.06(b)(ix).

      such structure or capitalization.

            (b) Before giving effect to the transactions contemplated by this
      Agreement, there shall have occurred no Material Adverse Change since

      legality, validity or enforceability of this Agreement, any Note, any
      other Loan Document, any Related Document or the consummation of the
      transactions contemplated hereby.

            (d) The Lender Parties shall have completed a due diligence
      investigation of the Loan Parties (including, without limitation, a field

      financial information) furnished by or on behalf of any Loan Party to the
      Administrative Agent or any Lender Party was or has become misleading,

                                      65


      given such access to the management, records, books of account, contracts

      Parties.

            all documents evidencing other necessary corporate action and
            governmental approvals, if any, with respect to this Agreement, the
            Notes, each other Loan Document and each Related Document and of the

            (c) Compliance with Environmental Laws. Comply, and cause each of
      its Subsidiaries and all lessees and other Persons operating or occupying

      Environmental Laws and Environmental Permits; obtain and renew and cause
      each of its Subsidiaries to obtain and renew all Environmental Permits
      necessary for its operations and properties, except if the failure to

      to conduct, any investigation, study, sampling and testing, and undertake
      any cleanup, removal, remedial or other action necessary to remove and
      clean up all Hazardous Materials from any of its properties, in accordance
      with the requirements of all Environmental Laws, except if the failure to
      remove or clean up such Hazardous Materials is not reasonably likely to
      have a Material Adverse Effect; provided, however, that no Loan Party or
      any of its Subsidiaries shall be required to undertake any such cleanup,
      removal, remedial or other action to the extent that its obligation to do
      so is being contested in good faith and by proper proceedings and
      appropriate reserves are being maintained with respect to such
      circumstances.

            (d) Maintenance of Insurance. Maintain, and cause each of its
      Subsidiaries to maintain, insurance with responsible and reputable
      insurance companies or associations in such amounts and covering such

      reasonably likely to have a Material Adverse Effect) to preserve and
      maintain, its corporate existence, rights (charter and statutory),
      permits, licenses, approvals, privileges and franchises, except if the
      failure to preserve and maintain such permits, approvals or licenses is
      not reasonably likely to have a Material Adverse Effect; provided,
      however, that such Loan Party may consummate any merger or consolidation
      permitted under Section 5.02(d).

            (f) Visitation Rights. At any reasonable time and from time to time,
      upon reasonable prior notice, permit the Administrative Agent or any of

      within 90 days after such request, at the expense of the Borrower, a Phase
      I environmental site assessment report for any of its or its Subsidiaries'
      owned properties described in such request, prepared by an environmental
      consulting firm acceptable to the Administrative Agent (and, if based upon
      the recommendation of such environmental consulting firm, a Phase II
      environmental site assessment report) indicating the presence or absence
      of Hazardous Materials and the estimated cost of any compliance, removal
      or remedial action in connection with any Hazardous Materials on such
      properties; without limiting the generality of the foregoing, if the
      Administrative Agent determines at any time that a material risk exists
      that any such report will not be provided within the time referred to
      above, the Administrative Agent may retain an environmental consulting
      firm to prepare such report at the expense of the Borrower, and such Loan
      Party hereby grants and agrees to cause any Subsidiary that owns any
      property described in such request to grant at the time of such request,
      to the Administrative Agent or to any Lender Party who makes such request
      through the Administrative Agent, such firm and any agents or
      representatives thereof an irrevocable non-exclusive license, subject to
      the rights of tenants, to enter onto their respective properties to

      generally accepted accounting principles.

            (i) Maintenance of Properties, Etc. Maintain and preserve, and cause
      each of its Subsidiaries to maintain and preserve, all of its properties
      that are reasonably required in the conduct of its business in good
      working order and condition, ordinary wear and tear excepted, and except
      for properties that have become obsolete or no longer fit for their
      intended purposes.

            (j) Compliance with Terms of Leaseholds. Make all payments and
      otherwise perform all obligations in respect of all leases of real
      property to which such Loan Party or any of its Subsidiaries is a party,
      keep such leases in full force and effect and not allow such leases to
      lapse or be terminated or any rights to renew such leases to be forfeited
      or cancelled, except if the failure to make such payment, perform such
      obligations or keep such leases in full force and effect is not reasonably
      likely to have a Material Adverse Effect.

      entitled to make under such Related Document.

            (l) Transactions with Affiliates. Conduct, and cause each of its
      Subsidiaries to conduct, all transactions otherwise permitted under the
      Loan Documents with any of their Affiliates on terms that are fair and
      reasonable and no less favorable to such Loan Party or such Subsidiary
      than it would obtain in a comparable arm's-length transaction with a
      Person not an Affiliate.

            (m) Covenant to Give Security. In addition to the requirements of
      Section 5.01(o), upon the request of the Administrative Agent and at the
      expense of the Borrower, (i) within 10 days after such request, furnish to
      the Administrative Agent a description of the real and personal properties

      properties purported to be subject to the security agreements delivered
      pursuant to this Section 5.01(m), enforceable against all third parties in
      accordance with their terms, (iv) within 60 days after such request,

      clauses (i), (ii) and (iii) above, as to such security agreements being
      legal, valid and binding obligations of such Loan Party and its
      Subsidiaries enforceable in accordance with their terms and as to such
      other matters as the Administrative Agent may reasonably request, (v) at
      any time and from time to time promptly execute and deliver any and all

      Interest Period of three months.

            (o) Additional Loan Parties. Cause any newly organized or acquired
      Subsidiary of the Borrower, any Parent Guarantor, or any of their Ongoing
      Subsidiaries (other than any Subsidiary organized or located outside of
      the United States) to execute and deliver to the Administrative Agent as
      promptly as practicable and in any event within 30 days after the
      organization or acquisition of such Subsidiary (i) a security agreement
      supplement in the form of Exhibit A to the Security Agreement, (ii) a
      guaranty in form and substance satisfactory to the Administrative Agent
      and the Lender Parties and (iii) such other documents, agreements,

      Fiscal Year"), the amount specified above for such Fiscal Year exceeds the
      amount of Capital Expenditures made by the Borrower during such Fiscal
      Year (the amount of such excess being the "Excess Amount"), MEDIQ and its
      Ongoing Subsidiaries shall be entitled to make additional Capital
      Expenditures in the succeeding Fiscal Year in an amount (such amount being
      referred to herein as the "Carryover Amount") equal to the lesser of (i)
      the Excess Amount and (ii) 1/3 of the amount specified above for the Prior
      Fiscal Year and, provided still further that the amount of Capital
      Expenditures during any Fiscal Year may be increased by an amount equal to
      100% minus the applicable Recapture Percentage multiplied by the amount of
      Excess Cash Flow for the prior Fiscal Year ratably reduced by the sum of
      (A) the amount of any payment of dividends pursuant to Section
      5.02(g)(ii), (B) the amount of any repurchase of stock pursuant to Section

actions described in Section 6.01 or otherwise, make demand upon the Borrower
to, and forthwith upon such demand the Borrower will, pay to the Administrative
Agent on behalf of the Lender Parties in same day funds at the Administrative
Agent's office designated in such demand, for deposit in the L/C Cash Collateral
Account, an amount equal to the aggregate Available Amount of all Letters of
Credit then outstanding. If at any time the Administrative Agent determines that
any funds held in the L/C Cash Collateral Account are subject to any right or
claim of any Person other than the Administrative Agent and the Lender Parties
or that the total amount of such funds is less than the aggregate Available
Amount of all Letters of Credit, the Borrower will, forthwith upon demand by the
Administrative Agent, pay to the Administrative Agent, as additional funds to be
deposited and held in the L/C Cash Collateral Account, an amount equal to the
excess of (a) such aggregate Available Amount over (b) the total amount of
funds, if any, then held in the L/C Cash Collateral Account that the
Administrative Agent determines to be free and clear of any such right and
claim.

                                  ARTICLE VII

                               PARENT GUARANTIES

            SECTION 7.01. Guaranty. Each Parent Guarantor hereby unconditionally
and irrevocably guarantees the punctual payment when due, whether at stated
maturity, by acceleration or otherwise, of all Obligations of each Loan Party
now or hereafter existing under the Loan Documents, whether for principal,
interest, fees, expenses or otherwise (such Obligations being the "Guaranteed
Obligations"), and agrees to pay any and all expenses (including reasonable
counsel fees and expenses) incurred by the Agents or the Lender Parties in
enforcing any rights under this Guaranty. Without limiting the generality of the
<PAGE>

                                     106


foregoing, each Parent Guarantor's liability shall extend to all amounts that
constitute part of the Guaranteed Obligations and would be owed by any Loan
Party to the Administrative Agent, the Agents or any Lender Party under the Loan
Documents but for the fact that they are unenforceable or not allowable due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Borrower.

            SECTION 7.02. Guaranty Absolute. Each Parent Guarantor guarantees
that the Guaranteed Obligations will be paid strictly in accordance with the
terms of the Loan Documents, regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of the Administrative Agent or any other Secured Party with respect
thereto. The Obligations of each Parent Guarantor under this Guaranty are
independent of the Guaranteed Obligations or any other Obligations of any Loan
Party under the Loan Documents, and a separate action or actions may be brought
and prosecuted against any Parent Guarantor to enforce this Guaranty,
irrespective of whether any action is brought against any Loan Party or whether
any Loan Party is joined in any such action or actions. The liability of each
Parent Guarantor under this Guaranty shall be irrevocable, absolute and
unconditional irrespective of, and each Parent Guarantor hereby irrevocably
waives any defenses it may now or hereinafter have in any way relating to, any
or all of the following:

            (a) any lack of validity or enforceability of any Loan Document or
      any agreement or instrument relating thereto;

            (b) any change in the time, manner or place of payment of, or in any
      other term of, all or any of the Guaranteed Obligations or any other
      Obligations of any other Loan Party under the Loan Documents, or any other
      amendment or waiver of or any consent to departure from any Loan Document,
      including, without limitation, any increase in the Guaranteed Obligations
      resulting from the extension of additional credit to the Borrower or any
      of its Subsidiaries or otherwise;

            (c) any taking, exchange, release or non-perfection of any
      Collateral, or any taking, release or amendment or waiver of or consent to
      departure from any other guaranty, for all or any of the Guaranteed
      Obligations;

            (d) any manner of application of Collateral, or proceeds thereof, to
      all or any of the Guaranteed Obligations, or any manner of sale or other
      disposition of any Collateral for all or any of the Guaranteed Obligations
      or any other Obligations of any other Loan Party under the Loan Documents
      or any other assets of any Loan Party or any of its Subsidiaries;

            (e) any change, restructuring or termination of the corporate
      structure or existence of any Loan Party or any of its Subsidiaries; or
<PAGE>

                                     107


            (f) any other circumstance (including, without limitation, any
      statute of limitations) or any existence of or reliance on any
      representation by the Administrative Agent or any other Secured Party that
      might otherwise constitute a defense available to, or a discharge of, any
      Loan Party, any Parent Guarantor or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by the Administrative Agent or any other Secured
Party upon the insolvency, bankruptcy or reorganization of any Loan Party or
otherwise, all as though such payment had not been made.

            SECTION 7.03. Waiver. Each Parent Guarantor hereby waives
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Guaranteed Obligations and this Guaranty and any requirement that the
Administrative Agent or any other Secured Party protect, secure, perfect or
insure any Lien or any property subject thereto or exhaust any right or take any
action against any Loan Party or any other Person or any collateral. Each Parent
Guarantor acknowledges that it will receive direct and indirect benefits from
the financing arrangements contemplated by the Loan Documents and that the
waiver set forth in this Section 7.03 is knowingly made in contemplation of such
benefits.

            SECTION 7.04. Payments Free and Clear of Taxes, Etc. (a) Any and all
payments made by each Parent Guarantor hereunder or under the Notes shall be
made, in accordance with Section 2.11, free and clear of and without deduction
for any and all present or future Taxes. If any Parent Guarantor shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Administrative Agent or any other Secured Party, (i) the sum
payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section) the Administrative Agent or such other Secured Party (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) such Parent Guarantor shall make such deductions and
(iii) such Parent Guarantor shall pay the full amount deducted to the relevant
taxation authority or other authority in accordance with applicable law.

            (b) In addition, each Parent Guarantor agrees to pay any present or
future Other Taxes.

            (c) Each Parent Guarantor will indemnify the Administrative Agent
and each other Secured Party for the full amount of Taxes or Other Taxes
(including, without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section) paid by the Administrative
Agent or such other Secured Party (as the case may be) and any liability
(including penalties, additions to tax, interest and expenses) arising
<PAGE>

                                     108


therefrom or with respect thereto. This indemnification shall be made within 30
days from the date the Administrative Agent or such other Secured Party (as the
case may be) makes written demand therefor.

            (d) Within 30 days after the date of any payment of Taxes, the
Parent Guarantor will furnish to the Administrative Agent, at its address
referred to in Section 9.02, appropriate evidence of payment thereof. If no
Taxes are payable in respect of any payment hereunder by any Parent Guarantor
through an account or branch outside the United States or on behalf of such
Parent Guarantor by a payor that is not a United States person, such Parent
Guarantor will furnish, or will cause such payor to furnish, to the
Administrative Agent a certificate from each appropriate taxing authority or
authorities, or an opinion of counsel acceptable to the Administrative Agent, in
either case stating that such payment is exempt from or not subject to Taxes.
For purposes of this subsection (d), the terms "United States" and "United
States person" shall have the meaning specified in Section 7701 of the Internal
Revenue Code.

            (e) Without prejudice to the survival of any other agreement of any
Parent Guarantor hereunder, the agreements and obligations of such Parent
Guarantor contained in this Section 7.04 shall survive the payment in full of
the Guaranteed Obligations and all other amounts payable under this Guaranty.

            SECTION 7.05. Continuing Guaranty; Assignments. This Guaranty is a
continuing guaranty and shall (a) remain in full force and effect until the
later of the cash payment in full of the Guaranteed Obligations and all other
amounts payable under this Guaranty and the Termination Date, (b) be binding
upon each Parent Guarantor, its successors and assigns and (c) inure to the
benefit of and be enforceable by the Administrative Agent and the other Secured
Parties and their successors, transferees and assigns. Without limiting the
generality of the foregoing clause (c), any Lender Party may assign or otherwise
transfer all or any portion of its rights and obligations hereunder (including,
without limitation, all or any portion of its Commitment, the Advances owing to
it and the Note or Notes held by it) to any other Person, and such other Person
shall thereupon become vested with all the benefits in respect thereof granted
to such Lender herein or otherwise, in each case as provided in Section 9.07.

            SECTION 7.06. Subrogation. The Parent Guarantors will not exercise
any rights that it may now or hereafter acquire against the Borrower or any
other insider guarantor that arise from the existence, payment, performance or
enforcement of the Parent Guarantor's Obligations under this Agreement or any
other Loan Document, including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution or indemnification and any right to
participate in any claim or remedy of the Administrative Agent or any other
Secured Party against the Borrower or any other insider guarantor or any
collateral, whether or not such claim, remedy or right arises in equity or under
contract,
<PAGE>

                                     109


statute or common law, including, without limitation, the right to take or
receive from the Borrower or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim, remedy or right, unless and until
all of the Obligations and all other amounts payable under this Guaranty shall
have been paid in full in cash and the Commitments shall have expired or
terminated. If any amount shall be paid to the Parent Guarantor in violation of
the preceding sentence at any time prior to the later of the payment in full in
cash of the Guaranteed Obligations and all other amounts payable under this
Guaranty and the Termination Date, such amount shall be held in trust for the
benefit of the Administrative Agent and the Secured Parties and shall forthwith
be paid to the Administrative Agent to be credited and applied to the Guaranteed
Obligations and all other amounts payable under this Guaranty, whether matured
or unmatured, in accordance with the terms of the Loan Documents, or to be held
as collateral for any Guaranteed Obligations or other amounts payable under this
Guaranty thereafter arising. If (i) the Parent Guarantor shall make payment to
the Administrative Agent or any other Secured Party of all or any part of the
Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other
amounts payable under this Guaranty shall be paid in full in cash and (iii) the
Termination Date shall have occurred, the Administrative Agent, and the other
Secured Parties will, at the Parent Guarantor's request and expense, execute and
deliver to the Parent Guarantor appropriate documents, without recourse and
without representation or warranty, necessary to evidence the transfer by
subrogation to the Parent Guarantor of an interest in the Guaranteed Obligations
resulting from such payment by the Parent Guarantor.

                                 ARTICLE VIII

                                  THE AGENTS

            SECTION 8.01. Authorization and Action. Each Lender Party (in its
capacities as a Lender, the Issuing Bank (if applicable) and a potential Hedge
Bank) hereby appoints and authorizes each Agent to take such action as agent on
its behalf and to exercise such powers and discretion under this Agreement and
the other Loan Documents as are delegated to such Agent by the terms hereof and
thereof, together with such powers and discretion as are reasonably incidental
thereto. As to any matters not expressly provided for by the Loan Documents
(including, without limitation, enforcement or collection of the Notes), each
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Lenders (or all the Lenders to the extent required by 9.01) and such
instructions shall be binding upon all Lender Parties and all holders of Notes;
provided, however, that no Agent shall be required to take any action that
exposes such Agent to personal liability or that is contrary to this Agreement
or
<PAGE>

                                     110


applicable law. Each Agent agrees to give to each Lender Party prompt notice of
each notice given to it by the Borrower pursuant to the terms of this Agreement.

            SECTION 8.02. Agents' Reliance, Etc. None of the Agents nor any of
their directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken by it or them under or in connection with the Loan
Documents, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, each Agent: (a) may treat
the payee of any Note as the holder thereof until the Administrative Agent
receives and accepts an Assignment and Acceptance entered into by the Lender
that is the payee of such Note, as assignor, and an Eligible Assignee, as
assignee, as provided in Section 9.07; (b) may consult with legal counsel
(including counsel for any Loan Party), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (c) makes no warranty or representation to any Lender
Party and shall not be responsible to any Lender Party for any statements,
warranties or representations (whether written or oral) made in or in connection
with the Loan Documents; (d) shall not have any duty to ascertain or to inquire
as to the performance or observance of any of the terms, covenants or conditions
of any Loan Document on the part of any Loan Party or to inspect the property
(including the books and records) of any Loan Party; (e) shall not be
responsible to any Lender Party for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created
under or in connection with, any Loan Document or any other instrument or
document furnished pursuant thereto; and (f) shall incur no liability under or
in respect of any Loan Document by acting upon any notice, consent, certificate
or other instrument or writing (which may be by telegram, telecopy or telex)
believed by it to be genuine and signed or sent by the proper party or parties.

            SECTION 8.03. BNP, NationsBank and Affiliates. With respect to its
Commitments, the Advances made by it and the Notes issued to it, each of BNP and
NationsBank shall have the same rights and powers under the Loan Documents as
any other Lender Party and may exercise the same as though they were not Agents;
and the term "Lender Party" or "Lenders Parties" shall, unless otherwise
expressly indicated, include BNP in its individual capacity. Each of BNP and
NationsBank and their affiliates may accept deposits from, lend money to, act as
trustee under indentures of, accept investment banking engagements from and
generally engage in any kind of business with, any Loan Party, any of its
Subsidiaries and any Person who may do business with or own securities of any
Loan Party or any such Subsidiary, all as if BNP and NationsBank were not Agents
and without any duty to account therefor to the Lender Parties.

            SECTION 8.04. Lender Party Credit Decision. Each Lender Party
acknowledges that it has, independently and without reliance upon any Agent or
any other
<PAGE>

                                     111


Lender Party and based on the financial statements referred to in Section 4.01
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender Party
also acknowledges that it will, independently and without reliance upon any
Agent or any other Lender Party and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement.

            SECTION 8.05. Indemnification. (a) Each Lender Party severally
agrees to indemnify each Agent (to the extent not promptly reimbursed by the
Borrower) from and against such Lender Party's ratable share (determined as
provided below) of any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever that may be imposed on, incurred by, or asserted
against such Agent in any way relating to or arising out of the Loan Documents
or any action taken or omitted by such Agent under the Loan Documents; provided,
however, that no Lender Party shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from any Agent's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender Party
agrees to reimburse each Agent promptly upon demand for its ratable share of any
costs and expenses (including, without limitation, fees and expenses of counsel)
payable by the Borrower under Section 9.04, to the extent that such Agent is not
promptly reimbursed for such costs and expenses by the Borrower. For purposes of
this Section 8.05, the Lender Parties' respective ratable shares of any amount
shall be determined, at any time, according to the sum of (a) the aggregate
principal amount of the Advances outstanding at such time and owing to the
respective Lender Parties, (b) their respective Pro Rata Shares of the aggregate
Available Amount of all Letters of Credit outstanding at such time, (c) the
aggregate unused portions of their respective Term Commitments at such time and
(d) their respective Unused Working Capital Commitments and Unused Acquisition
Commitments at such time. In the event that any Defaulted Advance shall be owing
by any Defaulting Lender at any time, such Lender Party's Commitment with
respect to the Facility under which such Defaulted Advance was required to have
been made shall be considered to be unused for purposes of this Section 8.05(a)
to the extent of the amount of such Defaulted Advance. The failure of any Lender
Party to reimburse any Agent promptly upon demand for its ratable share of any
amount required to be paid by the Lender Party to such Agent as provided herein
shall not relieve any other Lender Party of its obligation hereunder to
reimburse each Agent for its ratable share of such amount, but no Lender Party
shall be responsible for the failure of any other Lender Party to reimburse any
Agent for such other Lender Party's ratable share of such amount. Without
prejudice to the survival of any other agreement of any Lender Party hereunder,
the agreement and obligations of each Lender Party contained in this Section
8.05(a) shall survive the payment in full of principal, interest and all other
amounts payable hereunder and under the other Loan Documents.
<PAGE>

                                     112


            (b) Each Lender Party severally agrees to indemnify the Issuing Bank
(to the extent not promptly reimbursed by the Borrower) from and against such
Lender Party's ratable share (determined as provided below) of any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against the Issuing Bank in any way
relating to or arising out of the Loan Documents or any action taken or omitted
by the Issuing Bank under the Loan Documents; provided, however, that no Lender
Party shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Issuing Bank's gross negligence or willful misconduct.
Without limitation of the foregoing, each Lender Party agrees to reimburse the
Issuing Bank promptly upon demand for its ratable share of any costs and
expenses (including, without limitation, fees and expenses of counsel) payable
by the Borrower under Section 9.04, to the extent that the Issuing Bank is not
promptly reimbursed for such costs and expenses by the Borrower. For purposes of
this Section 8.05(b), the Lender Parties' respective ratable shares of any
amount shall be determined, at any time, according to the sum of (a) the
aggregate principal amount of the Advances outstanding at such time and owing to
the respective Lender Parties, (b) their respective Pro Rata Shares of the
aggregate Available Amount of all Letters of Credit outstanding at such time,
(c) the aggregate unused portions of their respective Term Commitments at such
time plus (d) their respective Unused Working Capital Commitments and Unused
Acquisition Commitments at such time. In the event that any Defaulted Advance
shall be owing by any Defaulting Lender at any time, such Lender Party's
Commitment with respect to the Facility under which such Defaulted Advance was
required to have been made shall be considered to be unused for purposes of this
Section 8.05(b) to the extent of the amount of such Defaulted Advance. The
failure of any Lender Party to reimburse the Issuing Bank promptly upon demand
for its ratable share of any amount required to be paid by the Lender Parties to
the Issuing Bank as provided herein shall not relieve any other Lender Party of
its obligation hereunder to reimburse the Issuing Bank for its ratable share of
such amount, but no Lender Party shall be responsible for the failure of any
other Lender Party to reimburse the Issuing Bank for such other Lender Party's
ratable share of such amount. Without prejudice to the survival of any other
agreement of any Lender Party hereunder, the agreement and obligations of each
Lender Party contained in this Section 8.05(b) shall survive the payment in full
of principal, interest and all other amounts payable hereunder and under the
other Loan Documents.

            SECTION 8.06. Successor Agents. Any Agent may resign at any time by
giving written notice thereof to the Lender Parties. Upon any such resignation
or removal, the Required Lenders shall have the right to appoint a successor
Agent, subject to the approval of the Borrower which shall not be unreasonably
withheld or delayed. If no successor Agent shall have been so appointed by the
Required Lenders, and shall have accepted such appointment, within 30 days after
the retiring Agent's giving of notice of resignation, the retiring Agent may, on
behalf of the Lender Parties, appoint a successor
<PAGE>

                                     113


Agent, subject to the approval of the Borrower which shall not be unreasonably
withheld or delayed, which shall be a commercial bank organized under the laws
of the United States or of any State thereof and having a combined capital and
surplus of at least $500,000,000. Upon the acceptance of any appointment as
Agent hereunder by a successor Agent and upon the execution and filing or
recording of such financing statements, or amendments thereto, and such
amendments or supplements to the Mortgages, and such other instruments or
notices, as may be necessary or desirable, or as the Required Lenders may
request, in order to continue the perfection of the Liens granted or purported
to be granted by the Collateral Documents, such successor Agent shall succeed to
and become vested with all the rights, powers, discretion, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations under the Loan Documents. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article VIII shall inure
to its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement.

                                  ARTICLE IX

                                 MISCELLANEOUS

            SECTION 9.01. Amendments, Etc. No amendment or waiver of any
provision of this Agreement or the Notes or any other Loan Document, nor consent
to any departure by any Loan Party therefrom, shall in any event be effective
unless the same shall be in writing and signed (or, in the case of the
Collateral Documents, consented to) by the Required Lenders, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given; provided, however, that (a) no amendment,
waiver or consent shall, unless in writing and signed by all of the Lenders
(other than any Lender Party that is, at such time, a Defaulting Lender), do any
of the following at any time: (i) waive any of the conditions specified in
Section 3.01 or, in the case of the Initial Extension of Credit, Section 3.02 or
3.03, (ii) change the number of Lenders or the percentage of (x) the

hereunder, (iii) release all or substantially all of the Collateral in any

Loan Documents or (iv) amend this Section 9.01 and (b) no amendment, waiver or

Acquisition Facility or Working Capital Facility if affected by such amendment,
waiver or consent, (i) increase the Commitments of such Lender or subject such
Lender to any additional obligations,

                                     114


(ii) reduce the principal of, or interest on, the Notes held by such Lender or
any fees or other amounts payable hereunder to such Lender, (iii) postpone any

such Lender or any fees or other amounts payable hereunder to such Lender or
(iv) change the order of application of any prepayment set forth in Section 2.06
in any manner that materially affects such Lender; provided further that no
amendment, waiver or consent shall, unless in writing and signed by the Issuing
Bank, in addition to the Lenders required above to take such action, affect the
rights or obligations of the Issuing Bank under this Agreement; and provided
further that no amendment, waiver or consent shall, unless in writing and signed
by any Agent in addition to the Lenders required above to take such action,
affect the rights or duties of such Agent under this Agreement.

(A) all due diligence, collateral review, syndication, transportation, computer,
duplication, appraisal, audit, insurance, consultant, search, filing and
recording fees and expenses and (B) the reasonable fees and expenses of counsel
for the Administrative Agent with respect thereto, with respect to advising the
Administrative Agent as to its rights and responsibilities, or the perfection,
protection or preservation of rights or interests, under the Loan Documents,
with respect to negotiations with any Loan Party or with other creditors of any
Loan Party or any of its Subsidiaries arising out of any Default or any events
or circumstances that may give rise to a Default and with respect to presenting
claims in or otherwise participating in or monitoring any bankruptcy, insolvency
or other similar proceeding involving creditors' rights generally and any
proceeding ancillary thereto) and (ii) all reasonable out-of-pocket costs and
expenses of the Administrative Agents and the Lender Parties in connection with
the enforcement of the Loan Documents, whether in any action, suit or
litigation, any bankruptcy, insolvency or other similar proceeding affecting
creditors' rights generally (including, without limitation, the reasonable fees
and expenses of counsel for the Administrative Agent and each Lender Party with
respect thereto).

            (b) The Borrower agrees to indemnify and hold harmless each Agent,
each Lender Party and each of their Affiliates and their officers, directors,
employees, agents and advisors (each, an "Indemnified Party") from and against
any and all claims, damages, losses, liabilities and reasonable out-of-pocket
expenses (including, without limitation, reasonable fees and expenses of
counsel) that may be incurred by or asserted or awarded against any Indemnified
Party, in each case arising out of or in connection with or by reason of, or in
connection with the preparation for a defense of, any investigation, litigation
or proceeding arising out of, related to or in connection with (i) the
Facilities, the actual or proposed use of the proceeds of the Advances or the
Letters of Credit, the Loan Documents or any of the transactions contemplated
thereby (including, without limitation, the Refinancing and any of the other
transactions contemplated hereby) or (ii) the actual or alleged presence of
Hazardous Materials on any property of any Loan Party or any of its Subsidiaries
or any Environmental Action relating in any way to any Loan Party or any of its
Subsidiaries, in each case whether or not such investigation, litigation or
proceeding is brought by any Loan Party, its directors, shareholders or
creditors or an Indemnified Party or any Indemnified Party is otherwise a party
thereto and whether or not the transactions contemplated hereby are consummated,
except to the extent such claim, damage, loss, liability or expense is found in
a final, non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnified Party's gross negligence or willful misconduct.
The Borrower also agrees not to assert any claim against any Agent, any Lender
Party or any of their Affiliates, or any of their respective officers,
directors, employees, attorneys and agents, on any theory of liability, for
special, indirect,
<PAGE>

                                     116


consequential or punitive damages arising out of or otherwise relating to the
Facilities, the actual or proposed use of the proceeds of the Advances or the
Letters of Credit, the Loan Documents or any of the transactions contemplated
thereby.

            (c) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance is made by the Borrower to or for the account of a Lender Party
other than on the last day of the Interest Period for such Advance, as a result
of a payment pursuant to Section 2.05, a payment or Conversion pursuant to
Section 2.09(b)(i) or 2.10(d), acceleration of the maturity of the Notes
pursuant to Section 6.01 or for any other reason, or by an Eligible Assignee to
a Lender Party other than on the last day of the Interest Period for such
Advance upon an assignment of rights and obligations under this Agreement
pursuant to Section 9.07 as a result of a demand by the Borrower pursuant to
Section 9.07(a), the Borrower shall, upon demand by the Administrative Agent on
behalf of a Lender Party, pay to the Administrative Agent for the account of
such Lender Party any amounts required to compensate such Lender Party for any
additional losses, costs or expenses that it may reasonably incur as a result of
such payment, including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender Party to fund or
maintain such Advance. The calculations of any amounts required to be paid by
the Borrower pursuant to this Section 9.04(c) shall be provided by the
Administrative Agent to the Borrower.

            (d) If any Loan Party fails to pay when due any costs, expenses or
other amounts payable by it under any Loan Document, including, without
limitation, fees and expenses of counsel and indemnities, such amount may be
paid on behalf of such Loan Party by any Agent or any Lender Party, in its sole
discretion.

            (e) Without prejudice to the survival of any other agreement of any
Loan Party hereunder or under any other Loan Document, the agreements and
obligations of the Borrower contained in Sections 2.10 and 2.12 and this Section
9.04 shall survive the payment in full of principal, interest and all other
amounts payable hereunder and under any of the other Loan Documents.

            SECTION 9.05. Right of Set-off. Upon (a) the occurrence and during
the continuance of any Event of Default and (b) the making of the request or the
granting of the consent specified by Section 6.01 to authorize the
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Lender Party and each of its respective
Affiliates is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender Party or such
Affiliate to or for the credit or the account of the Borrower against any and
all of the Obligations of the Borrower now or hereafter existing
<PAGE>

                                     117


under this Agreement and the Note or Notes (if any) held by such Lender Party,
irrespective of whether such Lender Party shall have made any demand under this
Agreement or such Note or Notes and although such obligations may be unmatured.
Each Lender Party agrees promptly to notify the Borrower after any such set-off
and application; provided, however, that the failure to give such notice shall
not affect the validity of such set-off and application. The rights of each
Lender Party and its respective Affiliates under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
set-off) that such Lender Party and its respective Affiliates may have.

            SECTION 9.06. Binding Effect. This Agreement shall become effective
when it shall have been executed by the Borrower and each Agent and when each
Agent shall have been notified by each Initial Lender and the Initial Issuing
Bank that such Initial Lender and the Initial Issuing Bank has executed it and
thereafter shall be binding upon and inure to the benefit of the Borrower, each
Agent and each Lender Party and their respective successors and assigns, except
that the Borrower shall not have the right to assign its rights hereunder or any
interest herein without the prior written consent of all of the Lender Parties.

            SECTION 9.07. Assignments and Participations. (a) Each Lender may
and, if demanded by the Borrower (following a demand by such Lender pursuant to
Section 2.10 or 2.12) upon at least 10 Business Days' notice to such Lender and
the Administrative Agent, will assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitment or Commitments, the Advances
owing to it and the Note or Notes held by it); provided, however, that (i) each
such assignment shall be of a uniform, and not a varying, percentage of all
rights and obligations under and in respect of one or more Facilities, (ii)
except in the case of an assignment to a Person that, immediately prior to such
assignment, was a Lender or an assignment of all of a Lender's rights and
obligations under this Agreement, the amount of the Commitment of the assigning
Lender being assigned pursuant to each such assignment (determined as of the
date of the Assignment and Acceptance with respect to such assignment) shall in
no event be less than $5,000,000 and shall be in an integral multiple of
$500,000, or, if the aggregate amount of the Commitment of such assigning Lender
is less than $5,000,000, all of such Lender's Commitment, (iii) each such
assignment shall be to an Eligible Assignee, (iv) each such assignment made as a
result of a demand by the Borrower pursuant to this Section 9.07(a) shall be
arranged by the Borrower after consultation with the Administrative Agent and
shall be either an assignment of all of the rights and obligations of the
assigning Lender under this Agreement or an assignment of a portion of such
rights and obligations made concurrently with another such assignment or other
such assignments that together cover all of the rights and obligations of the
assigning Lender under this Agreement, (v) no Lender shall be obligated to make
any such assignment as a result of the demand by the Borrower pursuant to this
Section 9.07(a) unless and until such Lender shall have received one or more
payments from either
<PAGE>

                                     118


the Borrower or one or more Eligible Assignees in an aggregate amount at least
equal to the aggregate outstanding principal amount of the Advances owing to
such Lender, together with accrued interest thereon to the date of payment of
such principal amount and all other amounts payable to such Lender under this
Agreement, (vi) no such assignments shall be permitted without the consent of
the Administrative Agent until the Administrative Agent shall have notified the
Lender Parties that syndication of the Commitments hereunder has been completed
as determined by the Agents, and (vii) the parties to each such assignment shall
execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with any Note
or Notes subject to such assignment and a processing and recordation fee of
$3,000.

            (b) Upon such execution, delivery, acceptance and recording, from
and after the effective date specified in such Assignment and Acceptance, (x)
the assignee thereunder shall be a party hereto and, to the extent that rights
and obligations hereunder have been assigned to it pursuant to such Assignment
and Acceptance, have the rights and obligations of a Lender or Issuing Bank, as
the case may be, hereunder and (y) the Lender or Issuing Bank assignor
thereunder shall, to the extent that rights and obligations hereunder have been
assigned by it pursuant to such Assignment and Acceptance, relinquish its rights
and 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 or Issuing Bank's rights and obligations under this
Agreement, such Lender or Issuing Bank shall cease to be a party hereto).

            (c) By executing and delivering an Assignment and Acceptance, the
Lender Party assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender Party makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or any other Loan Document or the execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created
under or in connection with, this Agreement or any other Loan Document or any
other instrument or document furnished pursuant hereto or thereto; (ii) such
assigning Lender Party makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Borrower or any
other Loan Party or the performance or observance by any Loan Party of any of
its obligations under any Loan Document or any other instrument or document
furnished pursuant thereto; (iii) such assignee confirms that it has received a
copy of this Agreement, together with copies of the financial statements
referred to in Section 4.01 and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to enter into
such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon the Administrative Agent, such assigning Lender Party or
any other Lender Party and based on such documents and information as it shall
<PAGE>

                                     119


deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee confirms
that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers and discretion under the Loan Documents as are delegated to the
Administrative Agent by the terms hereof, together with such powers and
discretion as are reasonably incidental thereto; and (vii) such assignee agrees
that it will perform in accordance with their terms all of the obligations which
by the terms of this Agreement are required to be performed by it as a Lender or
Issuing Bank, as the case may be.

            (d) The Administrative Agent, acting for this purpose (but only for
this purpose) solely as the agent of the Borrower, shall maintain at its address
referred to in Section 9.02 a copy of each Assignment and Acceptance delivered
to and accepted by it and a register for the recordation of the names and
addresses of the Lender Parties and the Commitment under each Facility of, and
principal amount of the Advances owing under each Facility to, each Lender Party
from time to time (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
Borrower, each Agent and the Lender Parties may treat each Person whose name is
recorded in the Register as a Lender Party hereunder for all purposes of this
Agreement. The Register shall be available for inspection by the Borrower or any
Lender Party 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 Party and an assignee, together with any Note or Notes subject
to such assignment, the Administrative Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of Exhibit C
hereto, (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
Borrower. In the case of any assignment by a Lender, within five Business Days
after its receipt of such notice, the Borrower, at its own expense, shall
execute and deliver to the Administrative Agent in exchange for the surrendered
Note or Notes a new Note to the order of such Eligible Assignee in an amount
equal to the Commitment assumed by it under a Facility pursuant to such
Assignment and Acceptance and, if the assigning Lender has retained a Commitment
hereunder under such Facility, a new Note to the order of the assigning Lender
in an amount equal to the Commitment retained by it hereunder. Such new Note or
Notes shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Note or Notes, shall be dated the effective date of
such Assignment and Acceptance and shall otherwise be in substantially the form
of Exhibit A-1, A-2, A-3 or A-4 hereto, as the case may be.

            (f) Each Lender Party may sell participations in or to all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitments, the Advances owing to it and
the Note or Notes (if any) held by it) to any
<PAGE>

                                     120


Person other than any Loan Party or any of its Subsidiaries or Affiliates;
provided, however, that (i) such Lender Party's obligations under this Agreement
(including, without limitation, its Commitments) shall remain unchanged, (ii)
such Lender Party shall remain solely responsible to the other parties hereto
for the performance of such obligations, (iii) such Lender Party shall remain
the holder of any such Note for all purposes of this Agreement, (iv) the
Borrower, each Agent and the other Lender Parties shall continue to deal solely
and directly with such Lender Party in connection with such Lender Party's
rights and obligations under this Agreement and (v) no participant under any
such participation shall have any right to approve any amendment or waiver of
any provision of any Loan Document, or any consent to any departure by any Loan
Party therefrom, except to the extent that such amendment, waiver or consent
would reduce the principal of, or interest on, the Notes or any fees or other
amounts payable hereunder, in each case to the extent subject to such
participation, postpone any date fixed for any payment of principal of, or
interest on, the Notes or any fees or other amounts payable hereunder, in each
case to the extent subject to such participation, or release all or
substantially all of the Collateral.

            (g) Any Lender Party may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower furnished to such Lender
Party by or on behalf of the Borrower; provided, however, that, prior to any
such disclosure, the assignee or participant or proposed assignee or participant
shall agree to preserve the confidentiality of any Confidential Information
received by it from such Lender Party.

            (h) Notwithstanding any other provision set forth in this Agreement,
any Lender Party may at any time create a security interest in all or any
portion of its rights under this Agreement (including, without limitation, the
Advances owing to it and the Note or Notes held by it) including, without
limitation, in favor of any Federal Reserve Bank in accordance with Regulation A
of the Board of Governors of the Federal Reserve System.

            SECTION 9.08. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.

            SECTION 9.09. No Liability of the Issuing Bank. The Borrower assumes
all risks of the acts or omissions of any beneficiary or transferee of any
Letter of Credit with respect to its use of such Letter of Credit. Neither the
Issuing Bank nor any of its officers or directors shall be liable or responsible
for: (a) the use that may be made of any Letter of Credit or any acts or
omissions of any beneficiary or transferee in connection therewith;
<PAGE>

                                     121


(b) the validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (c) payment by the Issuing Bank
against presentation of documents that do not comply with the terms of a Letter
of Credit, including failure of any documents to bear any reference or adequate
reference to the Letter of Credit; or (d) any other circumstances whatsoever in
making or failing to make payment under any Letter of Credit, except that the
Borrower shall have a claim against the Issuing Bank, and the Issuing Bank shall
be liable to the Borrower, to the extent of any direct, but not consequential,
damages suffered by the Borrower that the Borrower proves were caused by (i) the
Issuing Bank's willful misconduct or gross negligence in determining whether
documents presented under any Letter of Credit comply with the terms of the
Letter of Credit or (ii) the Issuing Bank's willful failure to make lawful
payment under a Letter of Credit after the presentation to it of a draft and
certificates strictly complying with the terms and conditions of the Letter of
Credit. In furtherance and not in limitation of the foregoing, the Issuing Bank
may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.

            SECTION 9.10. Jurisdiction, Etc. (a) Each of the parties hereto
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or federal court of
the United States of America sitting in New York City, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any of the other Loan Documents to which it is a party, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the extent permitted by law, in such federal court. Each of the
parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that any party may otherwise have to bring any action or
proceeding relating to this Agreement or any of the other Loan Documents in the
courts of any jurisdiction.

            (b) Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or any of the
other Loan Documents to which it is a party in any New York State or federal
court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

            SECTION 9.11. Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.

            SECTION 9.12. Waiver of Jury Trial. Each of the Borrower, each Agent
and the Lender Parties irrevocably waives all right to trial by jury in any
action, proceeding or counterclaim (whether based on contract, tort or
otherwise) arising out of or relating to any of the Loan Documents, the Advances
or the actions of any Agent or any Lender Party in the negotiation,
administration, performance or enforcement thereof.

            IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed by their respective officers thereunto duly authorized, as of the
date first above written.

          SECTION 2. Security for Obligations. This Agreement secures, in the
case of each Grantor, the payment of all Obligations of such Grantor now or
hereafter existing under the Loan Documents, whether direct or indirect,
absolute or contingent, including any extensions, modifications, substitutions,
amendments and renewals thereof, whether for principal (including reimbursement
for amounts drawn under Letters of Credit), interest, premiums, penalties, fees,
indemnifications, contract causes of action, costs, expenses or otherwise (all
such Obligations secured hereby being the "Secured Obligations"). Without
limiting the generality of the foregoing, this Agreement secures, as to each
Grantor, the payment of all amounts that constitute part of the Secured
Obligations of such Grantor and that would be owed by such Grantor to the
Secured Parties under the Loan Documents but for the fact that they are
unenforceable or not allowable due to the existence of a bankruptcy,
reorganization or similar proceeding involving such Grantor.

          SECTION 3. Grantors Remain Liable. Anything contained herein to the
contrary notwithstanding, (a) each Grantor shall remain liable under the
contracts and agreements included in the Collateral to the extent set forth
therein to perform all of its duties and obligations thereunder to the same
extent as if this Agreement had not been executed, (b) the exercise by the
Administrative Agent of any of its rights hereunder shall not release any
Grantor from any of its duties or obligations under the contracts and agreements
included in the Collateral, and (c) no Secured Party shall have any obligation
or liability under the contracts and agreements included in the Collateral by
reason of this Agreement or any other Loan Document, nor shall any Secured Party
be obligated to perform any of the obligations or duties of any Grantor
thereunder or to take any action to collect or enforce any claim for payment
assigned hereunder.

          SECTION 4. Delivery of Security Collateral, Account Collateral,
Agreement Collateral and Receivables. All certificates or instruments
representing or evidencing any Security Collateral, Account Collateral,
Agreement Collateral or Receivables (and, to the extent requested by the
Administrative Agent, representing or evidencing any other Collateral) shall be
delivered to and held by or on behalf of the Administrative Agent pursuant
hereto and shall be in suitable form for transfer by delivery, or shall be
accompanied by duly executed instruments of transfer or assignment in blank, all
in form and substance satisfactory to the Administrative Agent; provided,
however, that this Section 4 shall not apply to any certificate of title
representing automotive equipment, trucks and motor vehicles referred to in
Section 1(c). Upon and after an Event of Default, the Administrative Agent shall
have the right, at any time in its discretion and without notice to any Grantor,
to

<PAGE>

                                        7


transfer to or to register in the name of the Administrative Agent or any of its
nominees any or all of the Security Collateral and Account Collateral, subject
only to the revocable rights specified in Section 14(a). In addition, upon and
after an Event of Default, the Administrative Agent shall have the right at any
time to exchange certificates or instruments representing or evidencing the
Security Collateral or Account Collateral for certificates or instruments of
smaller or larger denominations.

          SECTION 5. Maintaining the L/C Cash Collateral Account and the Asset
Sale Blocked Account. (a) So long as any Advance shall remain unpaid, any Letter
of Credit or Bank Hedge Agreement shall be outstanding or any Lender Party shall
have any Commitment under the Credit Agreement:

          (i) The Borrower will maintain the L/C Cash Collateral Account with
     BNP.

          (ii) It shall be a term and condition of the L/C Cash Collateral
     Account, notwithstanding any term or condition to the contrary in any other
     agreement relating to the L/C Cash Collateral Account, and except as
     otherwise provided by the provisions of Section 20, that no amount
     (including interest on Collateral Investments) shall be paid or released to
     or for the account of, or withdrawn by or for the account of, the Borrower
     or any other Person from the L/C Cash Collateral Account.

     (b) All Excess Cash from Permitted Asset Sales shall be promptly deposited
in the Asset Sale Blocked Account. It shall be a term and condition of the Asset
Sale Blocked Account, and except as otherwise provided by the provisions of
Section 8 and Section 20, that no amount (including interest on Collateral
Investments) shall be paid or released to or for the account of, or withdrawn by
or for the account of, the Borrower or any other Person from the Asset Sale
Blocked Account, provided, however, that so long as no Default has occurred and
is continuing, upon the request of the Borrower, such interest shall be released
to the Borrower on the last day of each fiscal quarter.

The L/C Cash Collateral Account and the Asset Sale Blocked Account shall be
subject to such applicable laws, and such applicable regulations of the Board of
Governors of the Federal Reserve System and of any other appropriate banking or
governmental authority, as may now or hereafter be in effect.

          SECTION 6. Maintaining the Blocked Accounts. So long as any Advance
shall remain unpaid, any Letter of Credit or Bank Hedge Agreement shall be
outstanding or any Lender Party shall have any Commitment under the Credit
Agreement:

          (a) Each Grantor shall, to the extent such Grantor shall have at any
     time an aggregate amount on deposit in excess of $250,000, maintain blocked
     deposit accounts

<PAGE>

                                        8


     ("Blocked Accounts") only with banks ("Blocked Account Banks") that have
     entered into letter agreements in substantially the form of Exhibit A (or
     such other form as the Administrative Agent and such Grantor shall agree)
     with such Grantor and the Administrative Agent ("Blocked Account Letters").

          (b) At the end of each Business Day, the Grantors required to maintain
     Blocked Accounts pursuant to the foregoing paragraph shall deposit all cash
     in Blocked Accounts; provided, however, that the provisions of this Section
     6(b) shall not apply to (i) the Citibank Account and payments required to
     be made thereto and (ii) any deposit account held in the name of the
     Borrower at PNC Bank for miscellaneous cash receipts and payments thereto
     so long as the aggregate amount on deposit in such accounts shall not
     exceed $25,000.

          (c) Upon any termination of any Blocked Account Letter or other
     agreement with respect to the maintenance of a Blocked Account by any
     Grantor required to maintain any Blocked Account pursuant to Section 6(a)
     or any Blocked Account Bank, such Grantor shall immediately notify all
     Obligors that were making payments to such Blocked Account to make all
     future payments to another Blocked Account. Following the occurrence and
     during the continuance of an Event of Default, such Grantor agrees to
     terminate any or all Blocked Accounts and Blocked Account Letters upon
     request by the Administrative Agent.

          SECTION 7. Investing of Amounts in the L/C Cash Collateral Account and
the Asset Sale Blocked Account. If requested by the Borrower, the Administrative
Agent will, subject to the provisions of Sections 8 and 20, from time to time
(a) invest amounts on deposit in the L/C Cash Collateral Account and the Asset
Sale Blocked Account in such Cash Equivalents in the name of the Administrative
Agent or as to which all action required by Section 10 shall have been taken as
the Borrower may select and the Administrative Agent may approve and (b) invest
interest paid on the Cash Equivalents referred to in clause (a) above, and
reinvest other proceeds of any such Cash Equivalents that may mature or be sold,
in each case in such Cash Equivalents in the name of the Administrative Agent or
as to which all actions required by Section 10 shall have been taken as the
Borrower may select and the Administrative Agent may approve (the Cash
Equivalents referred to in clauses (a) and (b) above being collectively
"Collateral Investments"). Interest and proceeds that are not invested or
reinvested in Collateral Investments as provided above shall be deposited and
held in the L/C Cash Collateral Account or the Asset Sale Blocked Account, as
the case may be; provided, however, that so long as no Default has occurred and
is continuing, upon the request of the Borrower, such interest deposited and
held in the Asset Sale Blocked Account shall be released to the Borrower on the
last day of each fiscal quarter.

                                      9


          SECTION 8. Release of Amounts. Any amount on deposit in the Asset Sale
Blocked Account shall be released by the Administrative Agent in accordance with
the terms and conditions set forth in Section 2.16 of the Credit Agreement.

          SECTION 9. Representations and Warranties. Each Grantor represents and
warrants as follows:

          (a) Such Grantor is the legal and beneficial owner of the Collateral
     of such Grantor free and clear of any Lien, claim, option or right of
     others, except for the liens and security interests created under this
     Agreement or permitted by the Credit Agreement. No effective financing
     statement or other instrument similar in effect covering all or any part of
     such Collateral (including, without limitation, accounts and general
     intangibles relating to the Collateral) or listing such Grantor or any of
     its Subsidiaries or any trade name of such Grantor or any of its
     Subsidiaries as debtor with respect to Collateral is on file in any
     recording office, except such as may have been filed in favor of the
     Administrative Agent relating to the Loan Documents or as permitted by
     Section 5.02(a) of the Credit Agreement.

          (b) The Pledged Shares owned by such Grantor have been duly authorized
     and validly issued and are fully paid and non-assessable. The Pledged Debt
     held by such Grantor has been duly authorized, authenticated or issued and
     delivered, is the legal, valid and binding obligation of the issuers
     thereof and is not in default.

          (c) The Initial Pledged Shares owned by such Grantor constitute the
     percentage of the issued and outstanding shares of stock of the issuers
     thereof indicated on Schedule I hereto. The Initial Pledged Debt
     constitutes all of the outstanding indebtedness owed to such Grantor for
     money borrowed or for the deferred purchase price of property of the
     issuers thereof.

          (d) On the date hereof and thereafter on the most recent date on which
     a revised Schedule III is required to be furnished to the Administrative
     Agent pursuant to Section 11(d), all of the Equipment and Inventory of such
     Grantor, other than such Equipment and Inventory as has been rented or
     leased to such Grantor's customers, is located at the places specified in
     Schedule III hereto. The chief place of business and chief executive office
     of such Grantor and the office where such Grantor keeps its records
     concerning the Receivables, and the original copies of each Assigned
     Agreement and all originals of all Related Contracts and all chattel paper,
     if any, that evidence Receivables (other than (i) those delivered to the
     Administrative Agent and (ii) rental contracts located in the ordinary
     course of business at the Borrower's branch offices), are located at the
     address set forth on the signature pages hereto beneath such Grantor's
     name. Such Grantor has delivered to the Administrative Agent the originals
     of all agreements, certificates or instruments representing or

<PAGE>

                                       10


     evidencing any Collateral and all security therefor and guaranties thereof,
     in each case to the extent that the delivery thereof to the Administrative
     Agent is required under Section 4 above. None of the Receivables or
     Agreement Collateral is evidenced by a promissory note or other instrument
     that is required to be delivered to the Administrative Agent hereunder and
     has not been so delivered (other than promissory notes issued to the
     Borrower with respect to amounts due to the Borrower, in the ordinary
     course of business on a basis consistent with current practice).

          (e) The Assigned Agreements to which such Grantor is a party, true and
     complete copies of which have been furnished to each Lender Party, have
     been duly authorized, executed and delivered by all parties thereto, have
     not been amended or otherwise modified, are in full force and effect and
     are binding upon and enforceable against all parties thereto in accordance
     with their terms. There exists no default under any Assigned Agreement to
     which such Grantor is a party by any party thereto. Each party to any
     Assigned Agreement to which such Grantor is a party (other than such
     Grantor) has executed and delivered to such Grantor a consent, in
     substantially the form of Exhibit B hereto or otherwise in form and
     substance satisfactory to the Administrative Agent, to the assignment of
     the Agreement Collateral to the Administrative Agent for the benefit of the
     Secured Parties pursuant to this Agreement.

          (f) Such Grantor has no Blocked Accounts or other deposit accounts
     other than the Blocked Accounts listed on Part I of Schedule V hereto and
     the other deposit accounts listed on Part II of Schedule V hereto. Each
     Grantor has instructed all existing Obligors to make all payments to a
     Blocked Account to the extent required by the terms hereof.

          (g) This Agreement, the pledge of the Security Collateral pursuant
     hereto and the pledge and assignment of the Account Collateral pursuant
     hereto create in favor of the Administrative Agent for the benefit of the
     Secured Parties a valid and perfected security interest in the Collateral
     of such Grantor, securing the payment of the Secured Obligations of such
     Grantor, and all filings and other actions necessary or desirable to
     perfect and protect such security interest have been duly taken. Such
     security interest is subject in priority only to (i) the lien imposed on
     the Collateral pursuant to the 12.125% Indenture as in effect on the date
     of the Initial Extension of Credit, (ii) the existing lien of Meridian Bank
     on the promissory note issued by Medifac, Inc. to MEDIQ, (iii) the existing
     lien of Meridian Bank on the promissory note issued by Granary Partners,
     L.P. to MEDIQ, and (iv) the prior liens permitted under Section 5.02(a) of
     the Credit Agreement. Upon the release of the liens referred to in the
     foregoing clauses (i), (ii), (iii) and (iv), such security interest shall
     be a first priority security interest.

<PAGE>

                                       11

          (h) Such Grantor has no trade names except as set forth on Schedule IV
     hereto; such trade names were adopted in good faith; and, to the best of
     such Grantor's knowledge, there exist no adverse claims against such trade
     names as of the Closing Date.

          (i) No consent of any other Person and no authorization, approval or
     other action by, and no notice to or filing with, any governmental
     authority or regulatory body or other Person is required (i) for the grant
     by such Grantor of the assignment and security interest granted hereby, for
     the pledge by such Grantor of any Security Collateral hereunder or for the
     execution, delivery or performance of this Agreement by such Grantor, (ii)
     for the perfection or maintenance of the pledge, assignment and security
     interest created hereunder (including the first priority nature of such
     pledge, assignment and security interest, except as otherwise permitted),
     except for the filing of financing and continuation statements under the
     Uniform Commercial Code, which financing statements have been duly filed,
     or (iii) for the exercise by the Administrative Agent of its voting or
     other rights provided for in this Agreement or the remedies in respect of
     the Collateral pursuant to this Agreement, except as may be required in
     connection with the disposition of any portion of the Security Collateral
     by laws affecting the offering and sale of securities generally.

          (j) There are no conditions precedent to the effectiveness of this
     Agreement that have not been satisfied or waived.

          (k) Such Grantor has, independently and without reliance upon any
     Secured Party and based on such documents and information as it has deemed
     appropriate, made its own credit analysis and decision to enter into this
     Agreement, and such Grantor has established adequate means of obtaining
     from any other Loan Parties on a continuing basis information pertaining
     to, and is now and on a continuing basis will be completely familiar with,
     the financial condition, operations, properties and prospects of such other
     Loan Parties.

          SECTION 10. Further Assurances. (a) Each Grantor agrees that from time
to time, at the expense of such Grantor, such Grantor will promptly execute and
deliver all further instruments and documents, and take all further action, that
such Grantor believes may be necessary or desirable, or that the Administrative
Agent may reasonably request, in order to perfect and protect any pledge,
assignment or security interest granted or purported to be granted hereby or to
enable the Administrative Agent to exercise and enforce its rights and remedies
hereunder with respect to any Collateral. Without limiting the generality of the
foregoing, each Grantor will: (i) mark conspicuously (A) each invoice issued in
connection with the rental or lease of any Equipment or Inventory, from 60 days
after the Initial Extension of Credit, with the following legend: "THIS
EQUIPMENT MAY BE SUBJECT TO A SECURITY INTEREST GRANTED TO BANQUE NATIONALE DE
PARIS AS

                                       12


ADMINISTRATIVE AGENT" and (B) each Assigned Agreement of such Grantor included
in the Collateral, and each of its records pertaining to the Collateral, with a
legend, in form and substance satisfactory to the Administrative Agent,
indicating that such Collateral is subject to the security interest granted
hereby, (ii) if any Collateral shall be evidenced by a promissory note or other
instrument (other than promissory notes permitted pursuant to Section
5.02(f)(ix) of the Credit Agreement), deliver and pledge to the Administrative
Agent for the benefit of the Secured Parties hereunder such note or instrument
duly indorsed and accompanied by duly executed instruments of transfer or
assignment, all in form and substance satisfactory to the Administrative Agent,
(iii) deliver and pledge to the Administrative Agent for the benefit of the
Secured Parties hereunder certificates representing the Pledged Shares
accompanied by undated stock powers executed in blank and evidence that all
other action that the Administrative Agent may deem necessary or desirable in
order to perfect and protect the liens and security interests created under this
Agreement has been taken and (iv) execute and file such financing or
continuation statements, or amendments thereto, and such other instruments or
notices, as may be necessary or desirable, or as the Administrative Agent may
request, in order to perfect and preserve the pledge, assignment and security
interests granted or purported to be granted hereunder.

          (b) Each Grantor hereby authorizes the Administrative Agent to file
one or more financing or continuation statements, and amendments thereto,
relating to all or any part of the Collateral without the signature of such
Grantor where permitted by law. A photocopy or other reproduction of this
Agreement or any financing statement covering the Collateral or any part thereof
shall be sufficient as a financing statement where permitted by law.

          (c) Each Grantor will furnish to the Administrative Agent from time to
time statements and schedules further identifying and describing the Collateral
and such other reports in connection with the Collateral as the Administrative
Agent may reasonably request, all in reasonable detail.

          (d) The Borrower will furnish to the Administrative Agent, at any time
within six months prior to the fifth anniversary of the date hereof, an opinion
of counsel acceptable to the Required Lenders to the effect that all financing
or continuation statements have been filed, and all other action has been taken,
to perfect and validate continuously from the date hereof the pledge, assignment
and security interests granted hereunder (excluding, in the case of perfection,
any Collateral in which a security interest may not be perfected by the filing
of a financing statement under the Uniform Commercial Code of any jurisdiction).

          SECTION 11. As to Equipment and Inventory. Each Grantor shall:

          (a) On the date hereof and thereafter on the most recent date on which
     a revised Schedule III is required to be furnished to the Administrative
     Agent pursuant to Section 11(d), all of the Equipment and Inventory of such
     Grantor, other than such Equipment and Inventory as has been rented or
     leased to such Grantor's customers, shall be located at the places
     specified in Schedule III hereto or at such other places in jurisdictions
     where all action required by Section 10 shall have been taken with respect
     to such Equipment and Inventory.

          (b) Cause all of its Equipment and Inventory to be maintained and
     preserved, as is reasonably required in the conduct of its business, in
     good working order and condition, excluding (i) ordinary wear and tear and
     (ii) properties that have become obsolete or no longer fit for their
     intended purposes, and shall forthwith, or in the case of any loss or
     damage to any of such Equipment or Inventory as soon as practicable after
     the occurrence thereof, make or cause to be made all repairs, replacements
     and other improvements in connection therewith which are necessary or
     desirable to such end.

          (c) Pay promptly when due all property and other taxes, assessments
     and governmental charges or levies imposed upon, and all claims (including
     claims for labor, materials and supplies) against, the Equipment and
     Inventory; provided, however, that such Grantor shall not be required to
     pay or discharge any such tax, assessment, charge, levy or claim (x) that
     is being contested in good faith and by proper proceedings and as to which
     appropriate reserves are being maintained, or (y) in respect of which the
     Lien resulting therefrom, if any, attaches to its property and becomes
     enforceable against its other creditors, to the extent that the aggregate
     amount of all such taxes, assessments, charges or claims does not exceed
     $250,000.

          (d) Furnish to the Administrative Agent, at the same time as the
     quarterly financial statements are required to be furnished to the
     Administrative Agent pursuant to Section 5.03(c) of the Credit Agreement,
     unless no revisions are required, a revised Schedule III specifying each
     place where the Equipment and Inventory of such Grantor is located
     excluding such Equipment or Inventory rented or leased to such Grantor's
     customers. Such revised Schedule III shall be deemed to replace the then
     existing Schedule III and shall be of full force and effect as of the date
     of delivery of such Schedule to the Administrative Agent.

          (e) In the event that Equipment and/or Inventory of the Grantors with
     a book value equal to or greater than 10% of the aggregate book value of
     all Equipment and Inventory of the Grantors' is relocated, in one move or
     in a series of moves, from one county to another, furnish within five
     Business Days after such relocation

<PAGE>

                                       14

     notice of such relocation to the Administrative Agent (such notice to
     include the percentage book value of the relocated Equipment and Inventory
     and the old and new locations of such Equipment and Inventory).

          (f) For each leased location at which at any time Equipment and
     Inventory of the Grantors with a book value equal to or greater than 10% of
     the aggregate book value of the Equipment and Inventory is located, use its
     good faith efforts to furnish at such time to the Administrative Agent a
     landlord access letter or consent on terms and conditions reasonably
     acceptable to the Administrative Agent.

          SECTION 12. Insurance. (a) Each Grantor shall, at its own expense,
maintain insurance with respect to the Equipment and Inventory in such amounts,
against such risks, in such form and with such insurers, as shall be reasonably
satisfactory to the Administrative Agent from time to time. Each policy for
liability insurance shall provide for all losses to be paid on behalf of the
Administrative Agent and such Grantor as their interests may appear, and each
policy for property damage insurance shall provide for all losses (except for
losses of less than $1,000,000 per occurrence) to be paid directly to the
Administrative Agent, except to the extent permitted to be paid to a Grantor
pursuant to Section 12(b). Each such policy shall in addition (i) name such
Grantor and the Administrative Agent as insured parties thereunder (without any
representation or warranty by or obligation upon the Administrative Agent) as
their interests may appear, (ii) contain the agreement by the insurer that any
loss thereunder shall be payable to the Administrative Agent notwithstanding any
action, inaction or breach of representation or warranty by such Grantor, (iii)
provide that there shall be no recourse against the Administrative Agent for
payment of premiums or other amounts with respect thereto and (iv) provide that
at least 10 days' prior written notice of cancellation or of lapse shall be
given to the Administrative Agent by the insurer. Each Grantor shall, if so
requested by the Administrative Agent, deliver to the Administrative Agent
certificates evidencing such insurance, make the original policies of such
insurance reasonably available for inspection by the Administrative Agent and,
as often as the Administrative Agent may reasonably request, a report of a
reputable insurance broker with respect to such insurance. Further, each Grantor
shall, at the request of the Administrative Agent, duly exercise and deliver
instruments of assignment of such insurance policies to comply with the
requirements of Section 10 and cause the insurers to acknowledge notice of such
assignment.

          (b) Reimbursement under any insurance maintained by any Grantor
pursuant to this Section 12 may be paid directly to the Person who shall have
incurred liability covered by such insurance. In case of any loss involving
damage to Equipment or Inventory when subsection (c) of this Section 12 is not
applicable, such Grantor shall make or cause to be made the necessary repairs to
or replacements of such Equipment or Inventory, and any proceeds of insurance
properly received by or released to such Grantor

<PAGE>

                                       15


shall be used by such Grantor, except as otherwise required or permitted
hereunder or by the Credit Agreement to pay or as reimbursement for the cost of
such repairs or replacements.

          (c) Upon the occurrence and during the continuance of any Event of
Default, all insurance payments in respect of such Equipment or Inventory shall
be paid to and applied by the Administrative Agent as specified in Section
20(b).

          SECTION 13. Place of Perfection; Records; Collection of Receivables.
(a) Each Grantor shall keep its chief place of business and chief executive
office and the office where it keeps its records concerning the Collateral; and
the original copies of the Assigned Agreements of such Grantor, and all
originals of all chattel paper which evidences or constitutes Receivables (other
than rental contracts located in the ordinary course of business at the
Borrower's branch offices), at the location therefor specified in Section 9(d)
or, upon 30 days' prior written notice to the Administrative Agent, at such
other locations in a jurisdiction where all actions required by Section 10 shall
have been taken with respect to the Collateral. Each Grantor will hold and
preserve such records, Assigned Agreements and chattel paper and will permit
representatives of the Administrative Agent at any time during normal business
hours to inspect and make abstracts from such records and chattel paper.

          (b) Except as otherwise provided in this subsection (b), such Grantor
shall continue to collect, at its own expense, all amounts due or to become due
such Grantor under the Receivables and Related Contracts. In connection with
such collections, upon and after an Event of Default, such Grantor may take
(and, at the Administrative Agent's direction, shall take) such action as such
Grantor or the Administrative Agent may deem necessary or advisable to enforce
collection of the Receivables and Related Contracts; provided, however, that the
Administrative Agent shall have the right upon the occurrence and during the
continuance of an Event of Default and upon written notice to the Borrower of
its intention to do so, to notify the Obligors under any Receivables or Related
Contracts of the assignment of such Receivables or Related Contracts to the
Administrative Agent and to direct such Obligors to make payment of all amounts
due or to become due to such Grantor thereunder directly to the Administrative
Agent and, upon such notification and at the expense of such Grantor, to enforce
collection of any such Receivables or Related Contracts, and to adjust, settle
or compromise the amount or payment thereof, in the same manner and to the same
extent as such Grantor might have done. After receipt by such Grantor of the
notice from the Administrative Agent referred to in the proviso to the preceding
sentence, (i) all amounts and proceeds (including instruments) received by such
Grantor in respect of the Receivables or the Related Contracts shall be received
in trust for the benefit of the Administrative Agent hereunder, shall be
segregated from other funds of such Grantor and shall be forthwith paid over to
the Administrative Agent in the same form as so received (with any necessary
indorsement) to be applied as provided by the terms of the Credit Agreement and
(ii) such Grantor shall not adjust, settle or compromise the amount or payment
of any Receivable, release wholly or partly any obligor thereof, or allow any
credit or discount thereon.

          SECTION 14. Voting Rights; Dividends; Etc. (a) So long as no Default
under Section 6.01(a) or (f) of the Credit Agreement or Event of Default shall
have occurred and be continuing:

          (i) Each Grantor shall be entitled to exercise any and all voting and
     other consensual rights pertaining to the Security Collateral of such
     Grantor or any part thereof for any purpose not inconsistent with the terms
     of this Agreement or the other Loan Documents; provided, however, that no
     Grantor shall exercise or refrain from exercising any such right if, in the
     Administrative Agent's judgment, such action would have a material adverse
     effect on the value of the Security Collateral or any part thereof.

          (ii) Each Grantor shall be entitled to receive and retain any and all
     dividends and interest paid in respect of the Security Collateral of such
     Grantor if and to the extent that the payment thereof is not otherwise
     prohibited by the terms of the Loan Documents; provided, however, that any
     and all

               (A) dividends and interest paid or payable other than in cash in
          respect of, and instruments and other property received, receivable or
          otherwise distributed in respect of, or in exchange for, any Security
          Collateral,

               (B) dividends and other distributions paid or payable in cash in
          respect of any Security Collateral in connection with a partial or
          total liquidation or dissolution or in connection with a reduction of
          capital, capital surplus or paid-in-surplus, and

               (C) cash paid, payable or otherwise distributed in respect of
          principal of, or in redemption of, or in exchange for, any Security
          Collateral,

     shall be, and shall be forthwith delivered to the Administrative Agent to
     hold as, Security Collateral except as otherwise required under the Credit
     Agreement and shall, if received by any Grantor, be received in trust for
     the benefit of the Administrative Agent, be segregated from the other
     property or funds of such Grantor and be forthwith delivered to the
     Administrative Agent as Security Collateral in the same form as so received
     (with any necessary indorsement).

          (iii) The Administrative Agent shall execute and deliver (or cause to
     be executed and delivered) to each Grantor all such proxies and other
     instruments as such Grantor may reasonably request for the purpose of
     enabling such Grantor to exercise the voting and other rights that it is
     entitled to exercise pursuant to paragraph (i) above and to receive the
     dividends or interest payments that it is authorized to receive and retain
     pursuant to paragraph (ii) above.

<PAGE>

                                       17


          (b) Upon the occurrence and during the continuance of any Default
under Section 6.01(a) or (f) of the Credit Agreement or Event of Default:

          (i) All rights of each Grantor (A) to exercise or refrain from
     exercising the voting and other consensual rights that it would otherwise
     be entitled to exercise pursuant to Section 14(a)(i) shall, upon notice to
     such Grantor by the Administrative Agent, cease, and (B) to receive the
     dividends and interest payments that it would otherwise be authorized to
     receive and retain pursuant to Section 14(a)(ii) shall automatically cease,
     and all such rights shall thereupon become vested in the Administrative
     Agent, which shall thereupon have the sole right to exercise or refrain
     from exercising such voting and other consensual rights and to receive and
     hold as Security Collateral such dividends and interest payments.

          (ii) All dividends and interest payments that are received by any
     Grantor contrary to the provisions of paragraph (i) of this Section 14(b)
     shall be received in trust for the benefit of the Administrative Agent,
     shall be segregated from other funds of such Grantor and shall be forthwith
     paid over to the Administrative Agent as Security Collateral in the same
     form as so received (with any necessary indorsement).

          SECTION 15. As to the Assigned Agreements. (a) Each Grantor shall at
its expense:

          (i) perform and observe all the terms and provisions of the Assigned
     Agreements to be performed or observed by it, maintain the Assigned
     Agreements to which it is a party in full force and effect, enforce the
     Assigned Agreements in accordance with the terms thereof and take all such
     action to such end as may be requested from time to time by the
     Administrative Agent; and

          (ii) furnish to the Administrative Agent promptly upon receipt thereof
     copies of all notices, requests and other documents received by such
     Grantor under or pursuant to the Assigned Agreements to which it is a
     party, and from time to time (A) furnish to the Administrative Agent such
     information and reports regarding the Assigned Agreements and such other
     Collateral of such Grantor as the Administrative Agent may reasonably
     request, and (B) upon request of the Administrative Agent make to each
     other party to any Assigned Agreement to which it is a party such demands
     and requests for information and reports or for action as such Grantor is
     entitled to make thereunder.

          (b) Each Grantor agrees that it shall perform and observe all of the
terms and provisions of each Assigned Agreement to be performed or observed by
it, maintain each such Assigned Agreement in full force and effect, enforce such
Assigned Agreement in

<PAGE>

                                       18


accordance with its terms, take all such action to such end as may be from time
to time requested by the Administrative Agent.

          (c) Each Grantor hereby consents on its behalf and on behalf of its
Subsidiaries to the assignment and pledge to the Administrative Agent for the
ratable benefit of the Secured Parties of each Assigned Agreement to which it is
a party by any other Grantor hereunder.

          SECTION 16. Transfers and Other Liens; Additional Shares. (a) Each
Grantor agrees that it shall not (i) sell, assign (by operation of law or
otherwise), lease or otherwise dispose of, or grant any option with respect to,
any of the Collateral of such Grantor (other than sales, assignments, options,
leases and other dispositions permitted under the terms of the Credit Agreement
including, without limitation, Section 5.02(e) of the Credit Agreement) or (ii)
create or suffer to exist any Lien upon or with respect to any of the Collateral
of such Grantor, except for the Liens created under the Collateral Documents or
permitted under the Credit Agreement.

          (b) Each Grantor agrees that it shall (i) cause each issuer of the
Pledged Shares owned by such Grantor not to issue any stock or other securities
in addition to or in substitution for the Pledged Shares issued by such issuer,
except to such Grantor, and (ii) pledge hereunder, immediately upon its
acquisition (directly or indirectly) thereof, any and all additional shares of
stock or other securities of each issuer of any Pledged Shares.

          SECTION 17. Administrative Agent Appointed Attorney-in-Fact. Each
Grantor hereby irrevocably appoints for the term that this Agreement is in
effect the Administrative Agent such Grantor's attorney-in-fact, with full
authority in the place and stead of such Grantor and in the name of such Grantor
or otherwise, from time to time in the Administrative Agent's discretion, to
take any action and to execute any instrument that the Administrative Agent may
deem necessary or advisable to accomplish the purposes of this Agreement,
including, without limitation:

          (a) to obtain and adjust insurance required to be paid to the
     Administrative Agent pursuant to Section 12,

          (b) to ask for, demand, collect, sue for, recover, compromise, receive
     and give acquittance and receipts for moneys due and to become due under or
     in respect of any of the Collateral,

          (c) to receive, indorse and collect any drafts or other instruments,
     documents and chattel paper in connection with clause (a) or (b) above, and

<PAGE>

                                       19


          (d) to file any claims or take any action or institute any proceedings
     that the Administrative Agent may deem necessary or desirable for the
     collection of any of the Collateral or otherwise to enforce compliance with
     the terms and conditions of any Assigned Agreement or the rights of the
     Administrative Agent with respect to any of the Collateral.

          SECTION 18. Administrative Agent May Perform. If any Grantor fails to
perform any agreement contained herein, the Administrative Agent may, but
without any obligation to do so and without further notice, itself perform, or
cause performance of, such agreement, and the expenses of the Administrative
Agent incurred in connection therewith shall be payable by such Grantor under
Section 21.

          SECTION 19. The Administrative Agent's Duties. The powers conferred on
the Administrative Agent hereunder are solely to protect its and the other
Secured Parties' interest in the Collateral and shall not impose any duty upon
it to exercise any such powers. Except for the safe custody of any Collateral in
its possession and the accounting for moneys actually received by it hereunder,
the Administrative Agent shall have no duty as to any Collateral, as to
ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Security Collateral,
whether or not the Administrative Agent or any other Secured Party has or is
deemed to have knowledge of such matters, or as to the taking of any necessary
steps to preserve rights against any parties or any other rights pertaining to
any Collateral. The Administrative Agent shall be deemed to have exercised
reasonable care in the custody and preservation of any Collateral in its
possession if such Collateral is accorded treatment substantially equal to that
which it accords its own property.

          SECTION 20. Remedies. If any Event of Default shall have occurred and
be continuing:

          (a) The Administrative Agent may exercise in respect of the
     Collateral, in addition to other rights and remedies provided for herein or
     otherwise available to it, all the rights and remedies of a secured party
     upon default under the New York Uniform Commercial Code as in effect at
     such time (the "Code"), whether or not the Code applies to the affected
     Collateral, and also may (i) require any Grantor to, and each Grantor
     hereby agrees that it will at its expense and upon request of the
     Administrative Agent forthwith, assemble all or part of the Collateral as
     directed by the Administrative Agent and make it available to the
     Administrative Agent at a place and time to be designated by the
     Administrative Agent which is reasonably convenient to both parties; (ii)
     without notice except as specified below, sell the Collateral or any part
     thereof in one or more parcels at public or private sale, at any of the
     Administrative Agent's offices or elsewhere, for cash, on credit or for
     future delivery, and upon such other terms as the Administrative Agent may
     deem

<PAGE>

                                       20


     commercially reasonable; (iii) occupy any premises owned or leased by any
     Grantor where the Collateral or any part thereof is assembled or located
     for a reasonable period in order to effectuate its rights and remedies
     hereunder or under law, without obligation to such Grantor in respect of
     such occupation; and (iv) exercise any and all rights and remedies of any
     Grantor under or in connection with the Assigned Agreements, the
     Receivables and the Related Contracts or otherwise in respect of the
     Collateral, including, without limitation, any and all rights of such
     Grantor to demand or otherwise require payment of any amount under, or
     performance of any provision of, the Assigned Agreements, the Receivables
     and the Related Contracts. Each Grantor agrees that, to the extent notice
     of sale shall be required by law, at least ten days' notice to such Grantor
     of the time and place of any public sale or the time after which any
     private sale is to be made shall constitute reasonable notification. The
     Administrative Agent shall not be obligated to make any sale of Collateral
     regardless of notice of sale having been given. The Administrative Agent
     may adjourn any public or private sale from time to time by announcement at
     the time and place fixed therefor, and such sale may, without further
     notice, be made at the time and place to which it was so adjourned.

          (b) Any cash held by the Administrative Agent as Collateral and all
     cash proceeds received by the Administrative Agent in respect of any sale
     of, collection from, or other realization upon all or any part of the
     Collateral may, in the discretion of the Administrative Agent, be held by
     the Administrative Agent as collateral for, and/or then or at any time
     thereafter applied (after payment of any amounts payable to the
     Administrative Agent pursuant to Section 21) in whole or in part by the
     Administrative Agent for the ratable benefit of the Secured Parties against
     all or any part of the Secured Obligations as permitted or required by the
     Credit Agreement. Any surplus of such cash or cash proceeds held by the
     Administrative Agent and remaining after payment in full of all the Secured
     Obligations shall be paid over to the Grantor or to whomsoever may be
     lawfully entitled to receive such surplus.

          (c) All payments received by any Grantor under or in connection with
     any Assigned Agreement or otherwise in respect of the Collateral shall be
     received in trust for the benefit of the Administrative Agent and the other
     Secured Parties, shall be segregated from other funds of such Grantor and
     shall be forthwith paid over to the Administrative Agent in the same form
     as so received (with any necessary indorsement).

          (d) The Administrative Agent may, without notice to the Borrower
     except as required by law and at any time or from time to time, charge,
     set-off and otherwise apply all or any part of the Secured Obligations
     against the L/C Cash Collateral Account and the Asset Sale Blocked Account
     or any part thereof.

                                       21


          SECTION 21. Indemnity and Expenses. (a) Each Grantor agrees to defend,
protect, indemnify and hold harmless each Secured Party from and against any and
all claims, losses and liabilities growing out of or resulting from this
Agreement (including, without limitation, enforcement of this Agreement), except
claims, losses or liabilities resulting from such Secured Party's gross
negligence or willful misconduct as determined by a final judgment of a court of
competent jurisdiction.

          (b) Each Grantor will upon demand pay to the Administrative Agent the
amount of any and all reasonable expenses, including the reasonable fees and
expenses of its counsel and of any experts and agents, that the Administrative
Agent may incur in connection with (i) the administration of this Agreement,
(ii) the custody, preservation, use or operation of, or the sale of, collection
from or other realization upon, any of the Collateral of such Grantor, (iii) the
exercise or enforcement of any of the rights of the Administrative Agent or any
other Secured Party against such Grantor, or (iv) the failure by such Grantor to
perform or observe any of the provisions hereof.

          (c) Without prejudice to the survival of any other agreement of any
Loan Party hereunder or under any other Loan Document, the agreements and
obligations of the Grantors contained in this Section 21 shall survive the
payment in full of principal, interest and all other amounts payable hereunder
and under any of the other Loan Documents.

          SECTION 22. Security Interest Absolute. The obligations of each
Grantor under this Agreement are independent of the Secured Obligations, and a
separate action or actions may be brought and prosecuted against such Grantor to
enforce this Agreement, irrespective of whether any action is brought against
the other Grantors or whether the other Grantors are joined in any such action
or actions. All rights of the Administrative Agent and the pledge, assignment
and security interest hereunder, and all obligations of each Grantor hereunder,
shall be absolute and unconditional, irrespective of:

          (i) any lack of validity or enforceability of any Loan Document, any
     Hedge Agreement or any other agreement or instrument relating thereto;

          (ii) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Secured Obligations, or any other
     amendment or waiver of or any consent to any departure from any Loan
     Document or any Hedge Agreement, including, without limitation, any
     increase in the Secured Obligations resulting from the extension of
     additional credit to any Grantor or any of its Subsidiaries or otherwise;

          (iii) any taking, exchange, release or nonperfection of any other
     collateral, or any taking, release or amendment or waiver of or consent to
     departure from any guaranty, for all or any of the Secured Obligations;

<PAGE>

                                       22


          (iv) any manner of application of collateral, or proceeds thereof, to
     all or any of the Secured Obligations, or any manner of sale or other
     disposition of any collateral for all or any of the Secured Obligations or
     any other assets of the Borrower or any of its Subsidiaries;

          (v) any change, restructuring or termination of the corporate
     structure or existence of any Grantor or any of its Subsidiaries; or

          (vi) any other circumstance that might otherwise constitute a defense
     available to, or a discharge of, such Grantor or a third-party grantor of a
     security interest.

This Agreement shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Secured Obligations is rescinded or
must otherwise be returned by any Secured Party or by any other Person upon the
insolvency, bankruptcy or reorganization of any Loan Party or otherwise, all as
though such payment had not been made.

          SECTION 23. Amendments; Waivers; Etc. (a) No amendment or waiver of
any provision of this Agreement, and no consent to any departure by any Grantor
herefrom, shall in any event be effective unless the same shall be in writing
and signed by the Administrative Agent, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given. No failure on the part of the Administrative Agent to exercise, and no
delay in exercising, any right hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise of any such right preclude any other or
further exercise thereof or the exercise of any other right.

          (b) Upon the execution and delivery by any Person of a security
agreement supplement in substantially the form of Exhibit C hereto (each a

expense, execute and deliver to the Borrower such documents as the Borrower
shall reasonably request to evidence such termination.

be an original and all of which taken together shall constitute one and the same

     reasonable written request of the Administrative Agent in each instance,

law.

            2. Insurance. (a) That Mortgagor will keep the buildings on the
Premises and the Building Equipment insured for the benefit of Mortgagee (i)
against loss by fire, (ii) by means of an extended coverage endorsement, against
loss or damage by windstorm, hail, explosion, riot, riot attending a strike,
civil commotion, aircraft, vehicle and smoke, (iii) against loss of rentals due

(v) when and to the extent required by Mortgagee, against any other risk insured
against by persons operating like properties in the locality of the Premises;
that Mortgagor will assign and deliver to Mortgagee the policies of such
insurance and the proceeds thereof; that Mortgagor will reimburse Mortgagee for
any premiums paid for insurance made by Mortgagee on Mortgagor's default in
taking out such insurance, or in so delivering such policies, together with
interest thereon at the rate per annum specified in Article 4 hereof, and the
same shall be added to the indebtedness secured hereby and be secured by this
Mortgage;

losses thereunder shall be payable to Mortgagee pursuant to a standard
non-contributory mortgagee endorsement required by Mortgagee, which endorsement
may only be cancelled or modified upon not less than thirty (30) days prior

insurance companies, or payment or defense of lawsuits, and Mortgagor hereby

                                      5


            (c) that regardless of the types or amounts of insurance required
and approved by Mortgagee Mortgagor will deliver to Mortgagee certificates
evidencing all policies of insurance acquired by Mortgagor to insure against any
loss or damage to the Premises, as additional security for the indebtedness
secured hereby;

            (d) that Mortgagee shall be entitled to retain and apply the
proceeds of any insurance, whether against fire or other hazard, to the payment
of the indebtedness secured hereby, or, if Mortgagee, in its sole discretion,
shall so elect, Mortgagee may hold any or all of such proceeds for application
to payment of the cost of restoration;

            (e) that not less than fifteen (15) days prior to the expiration
date of each policy furnished by Mortgagor pursuant to this Article, Mortgagor
will deliver to Mortgagee a certificate evidencing a renewal policy or policies
marked "premium paid" or accompanied by other evidence of payment satisfactory

            (f) that in the event of a foreclosure of this Mortgage the
purchaser of the Premises shall succeed to all the rights of Mortgagor,
including any rights to the proceeds of insurance and to unearned premiums, in

            3. Premises and Improvements. That no building or other property now
or hereafter covered by the lien of this Mortgage shall be removed, demolished
or materially altered without the prior written consent of Mortgagee, except
that Mortgagor shall have the right, without such consent, to remove and dispose
of, free from the lien of this Mortgage, such Building Equipment as from time to
time may become worn out or obsolete, provided that simultaneously with or prior
to such removal, any such equipment shall be replaced with other equipment of a
value at least equal to that of the replaced equipment and free from any
security agreement, and by such removal and replacement Mortgagor shall be
deemed to have subjected such Building Equipment to lien of this Mortgage.

            4. Mortgagee's Optional Performance. That in the event of any
default in the performance of any of Mortgagor's covenants or agreements herein,
Mortgagee may, at the option of Mortgagee, perform the same and the cost
thereof, with interest at a rate per annum equal to the highest rate then
applicable to the indebtedness of Borrower to Mortgagee set forth in the Credit
Agreement (but not in excess of the maximum rate allowed by law to be charged to
Mortgagor), shall immediately be due from Mortgagor to Mortgagee and secured by
this Mortgage.

            5. Taxes, Assessments and Escrows. (a) That Mortgagor will pay all
taxes, assessments, water rates, sewer rents fines, impositions and other claims
and/or charges now or hereafter levied and all charges for utilities with
respect to or against the Premises or any part thereof, and also any and all
license fees or similar charges which may


<PAGE>

                                      6


be imposed by the municipality in which the Premises are situated for the use of
walks, chutes, areas and other space beyond the lot line on or abutting the
public sidewalks in front of or adjoining the Premises, together with any
penalties or interest on any of the foregoing (collectively "Impositions"), and
in default thereof Mortgagee may pay the same and Mortgagor will repay the same
with interest thereon at the rate per annum specified in Article 4 hereof and
the same shall be added to the indebtedness secured hereby and be additionally
secured by this Mortgage; that upon request of Mortgagee, Mortgagor will exhibit
to Mortgagee receipts for the payment of all items specified in this Article
within ten (10) days of the date when the same shall become delinquent. If any
law, rule, regulation or ordinance adopted hereafter by any federal, state or
local government, or any department, agency or bureau thereof, imposes a tax on
Mortgagee with respect to the Premises, the value of Mortgagor's equity therein,
the amount of the indebtedness secured hereby, or this Mortgage, Mortgagee shall
have the right at its election from time to time to give Mortgagor sixty (60)
days' written notice to pay such indebtedness secured hereby, whereupon such
indebtedness shall become due, payable and collectible at the expiration of such
period of sixty (60) days, unless prior thereto, lawfully and without violation
of usury or other laws, Mortgagor shall have paid any such tax in full as the
same became due and payable, in which event such notice shall be deemed to have
been rescinded with respect to any right of Mortgagee hereunder arising by
reason of the tax so paid. No prepayment charge or premium shall apply to the
payment of the indebtedness secured hereby pursuant to any such notice, if the
payment is made before the expiration of such period of sixty (60) days.

            (b) That Mortgagee will not permit Mortgagor to claim and Mortgagor
will not claim or demand any credit on or make any deduction from any secured
indebtedness hereunder including without limitation any interest or principal
of, on, or with respect to the Notes, by reason of the payment of any taxes
levied or to be levied upon the Premises or any part thereof during the
continuance of the lien of this Mortgage.

            (c) That, after an event of default hereunder, Mortgagee may, at its
option to be exercised by twenty (20) days' written notice to Mortgagor, require
that Mortgagor deposit with Mortgagee, on the first day of each and every month,
a sum equal to one-twelfth (1/12) of the annual real estate taxes, assessments,
water rates, sewer rents and other charges specified in this Article 5
(hereinafter collectively referred to as "taxes") plus one-twelfth (1/12) of the
premiums required to keep in force for one year the insurance specified in
Article 2 hereof. If such deposits shall be so required, Mortgagor shall also
deposit with Mortgagee, at least thirty (30) days prior to the due date of each
installment of such taxes and each insurance premium, such additional amount as
may be determined by Mortgagee in order to provide Mortgagee with funds
sufficient to pay such installment or premium. It is the intention of the
parties that, if such deposits shall be so required, Mortgagor shall deposit
with Mortgagee the necessary funds so that Mortgagee, at all times until the
full payment and satisfaction of this Mortgage, shall have on hand sufficient
deposits covering the accrued amounts of such taxes and insurance premiums. The
amount of such taxes and premiums,


<PAGE>

                                      7


when unknown, shall be reasonably estimated by Mortgagee; any insufficiency to
pay such charges when due shall be paid by Mortgagor to Mortgagee on demand. If
permitted by law, the said funds shall bear no interest and shall not be deemed
to be trust funds but may be commingled with other funds of Mortgagee and no
interest shall be payable upon any such funds. (The foregoing sentence shall not
apply to any assignee of this Mortgage.) Mortgagee shall have no obligation to
use said funds to pay an installment of taxes prior to the last day on which
payment thereof may be made without penalty or interest or to pay an insurance
premium prior to the due date thereof. If the whole of said principal sum and
interest shall be declared due and payable by Mortgagee pursuant to Article 20
hereof, all such deposits may, at the option of Mortgagee, be applied in
reduction of said principal sum and/or interest, as Mortgagee shall elect. Upon
an assignment of this Mortgage, Mortgagee shall have the right to pay over the
balance of such deposits in its possession to the assignee and Mortgagee shall
thereupon be completely released from all liability with respect to such
deposits and Mortgagor or owner of the Premises shall look solely to the
assignee or transferee in reference thereto. This provision shall apply to every
transfer of such deposited to a new assignee. Upon full payment and satisfaction
of this Mortgage or at any prior time, at the election of Mortgagee, the balance
of the deposits in its possession shall be paid over to the record owner of the
Premises and no other party shall have any right or claim thereto in any event.
Mortgagor agrees, at Mortgagee's request, to make the aforesaid deposits with
such service or financial institution as Mortgagee shall from time to time
designate.

            6. Appointment of Receiver and Other Powers. That Mortgagee shall
have the right in case of failure of Mortgagor to perform any of the acts,
covenants, or conditions in this Mortgage or in the Credit Agreement, upon a
complaint filed or any proper action being commenced for the foreclosure of this
Mortgage, to apply for, and Mortgagee shall be entitled as a matter of right
without consideration of the value of the Premises as security for the amounts
due Mortgagee, or of the solvency of any person or persons obligated for the
payment of such amounts, to the appointment by any competent court or tribunal,
without notice to any party, of a receiver of the rents, issues, and profits of
the Premises, with power to lease the Premises, or such part thereof as may not
then be under lease, and with such other powers as may be deemed necessary, who,
after deducting all proper charges and expenses attending the execution of the
trust as receiver, shall apply the residue of the rents and profits to the
payment and satisfaction of the amount remaining secured hereby, or to any
deficiency which may exist after applying the proceeds of any judicially decreed
sale of the Premises to the payment of the amount due, including interest and
the costs of the foreclosure and sale.

            7. Estoppel Certificate. That Mortgagor, within five (5) days upon
request in person or within ten (10) days upon request by mail, will furnish a
written statement duly acknowledged of the amount due on this Mortgage and
whether any offsets or defenses exist against the secured mortgage debt.


<PAGE>

                                      8


            8. Notice. That notice and demand or request shall be made in
accordance with the Credit Agreement.

            9. Title and Further Assurances. (a) That Mortgagor warrants that
Mortgagor has good title to the Premises, including without limitation the
Building Equipment and other property covered hereby free and clear of all liens
and encumbrances, except for current real property taxes not yet delinquent and
this Mortgage ("Permitted Encumbrances"), and has full power and lawful
authority to mortgage the same; that Mortgagor shall and will make, execute,
acknowledge and deliver, in due form required by applicable law, all such
further assurances as may at any time hereafter be reasonably required to
effectuate the mortgaging of the Premises and other property covered hereby or
intended so to be, unto Mortgagee, its successors or assigns, for the purpose
aforesaid, and unto all and every person or persons deriving any estate, right,
title or interest therein under this Mortgage; and that Mortgagor will warrant
and defend title to the Premises, including without limitation the Building
Equipment and said other property against all persons whomsoever claiming the
same or any part thereof, including without limitation all persons claiming by,
through or under Mortgagor.

            (b) That Mortgagor and shall execute and deliver, from time to time,
such further instruments (including further security agreements and Uniform
Commercial Code financing statements) as may be requested by Mortgagee to
confirm the lien of this Mortgage on any Building Equipment.

            (c) That Mortgagor upon request, shall make, execute and deliver any
and all instruments sufficient for the purpose of confirming the assignment to
Mortgagee of awards for the taking by eminent domain of the whole or any part of
the Premises or any easement therein, including any awards for changes of grade
of streets, free, clear and discharged of any encumbrances of any kind or nature
whatsoever.

            (d) That Mortgagor shall not further encumber the Premises for debt
and hereby (1) represents as a special inducement to Mortgagee to make the loans
secured hereby that, as of the date hereof, this is a first mortgage and there
are no encumbrances to secure debt junior to this Mortgage and (2) covenants
that there are to be none as of the date when this Mortgage becomes of record
and thereafter will be none, except, in either case, encumbrances having the
prior written consent of Mortgagee.

            (e) Mortgagor will promptly perform and observe, or cause to be
performed or observed, all of the terms, covenants and conditions of all
instruments of record affecting the Premises, non-compliance with which may
affect the security of this Mortgage or which may impose any duty or obligation
upon Mortgagor or any other occupant of the Premises or any part thereof, and
Mortgagor shall do or cause to be done all

                                      9


things necessary to preserve intact and unimpaired any and all easements,
appurtenances and other interest and rights in favor of or constituting any
portion of the Premises.

            10. Sale by Parcel. That in case of any foreclosure sale, the
Premises, or so much thereof as may be affected by this Mortgage, may be sold in
one or more parcels.

            11. Additional Lien. That if any action or proceeding be commenced
(including an action to foreclose this Mortgage or to collect the indebtedness
secured hereby), in which Mortgagee becomes a party or participates, by reason
of being the holder of this Mortgage or the debt secured hereby, all sums paid
by Mortgagee for the expense of so becoming a party or participating (including
reasonable counsel fees and disbursements) shall on notice and demand be paid by
Mortgagor, together with interest thereon at the rate per annum specified in
Article 4 hereof, and shall also be a lien on the Premises, prior to any right
or title to, interest in, or claim upon, the Premises subordinate to the lien of
this Mortgage, and shall be deemed to be additionally secured by this Mortgage
and that in any action or proceeding to foreclose this Mortgage, or to recover
or collect the debt secured hereby, the provisions of law respecting the
recovery of costs, disbursements and allowances shall apply in addition to the
foregoing.

            12. Care and Maintenance of Premises. That the Premises and any
buildings on the Premises have not been damaged to any material extent and
Mortgagor will maintain the Premises and the Building Equipment in good
condition and repair, will not commit or suffer any waste thereof or the conduct
of any nuisance or unlawful occupation or business on, or use of, the Premises,
and will comply with, or cause to be complied with, all statutes, ordinances and
requirements of any governmental authority relating to the Premises; that
Mortgagor will promptly repair, restore, replace or rebuild any part of the
Premises or the Building Equipment now or hereafter subject to the lien of this
Mortgage which may be damaged or destroyed by any casualty whatsoever or which
may be affected by any proceeding of the character referred to in Article 13;
and that Mortgagor shall not initiate, join in, or consent to any change in any
private restrictive covenant, zoning ordinance, or other public or private
restrictions, limiting or defining the uses which may be made of the Premises or
any part thereof.

            13. Eminent Domain and Condemnation. The proceeds of any award or
claim for damages, direct or consequential, in connection with any condemnation
or other taking of or damage or injury to the Premises, or any part thereof, or
for conveyance in lieu of condemnation, are hereby assigned to and shall be paid
to Mortgagee. In addition, all causes of action, whether accrued before or after
the date of this Mortgage, of all types for damages or injury or affecting the
Premises or any part thereof, including, without limitation, causes of action
arising in tort or contract and causes of action for fraud or concealment of a
material fact, are hereby assigned to Mortgagee as additional security and the
proceeds shall be paid to Mortgagee. Mortgagee may, at its option, appear in and

<PAGE>

                                      10


prosecute in its own name, any action or proceedings relating to condemnation or
other taking of or damage or injury to the Premises or any portion thereof. If
Mortgagor at any time suspects or has knowledge of any casualty damages to the
Premises or damage in any other manner, Mortgagor will immediately notify
Mortgagee in writing. Mortgagor may participate in any such proceedings and may
join Mortgagee in adjusting any loss covered by insurance.

            That notwithstanding any taking by eminent domain or other
governmental action (of which there are no such pending proceedings) causing
injury to, or decrease in value of, the Premises and creating a right to
compensation therefor, including, without limitation, the change of the grade of
any street, Mortgagor shall continue to be fully liable for all indebtedness or
liability secured hereby.

            All compensation, awards, proceeds, damages, claims, insurance
recoveries, rights of action and payments which Mortgagor may receive, or to
which Mortgagor may become entitled with respect to the Premises or any part
thereof, shall be paid over to Mortgagee and shall be applied first toward
reimbursement of all costs and expenses of Mortgagee in connection with recovery
of the same. Thereafter the same need not be applied by Mortgagee in reduction
of principal but may be applied in such proportions and priority as Mortgagee,
in Mortgagee's sole discretion, may elect, to the payment of principal, interest
or other sums secured by this Mortgage and/or to payment to Mortgagor, on such
terms as Mortgagee may specify, for the sole purpose of altering, restoring or
rebuilding any part of the Premises which may have been altered, damaged or
destroyed as a result of any such taking or other action; that if, prior to the
receipt by Mortgagee of such award or compensation, the Premises shall have been
sold on foreclosure of this Mortgage, Mortgagee shall have the right to receive
said award or compensation to the extent of any deficiency found to be due upon
such sale, with legal interest thereon, whether or not a deficiency judgment on
this Mortgage shall have been sought or recovered, together with reasonable
counsel fees and the costs and disbursements incurred by Mortgagee in connection
with the collection of such award or compensation. In the event Mortgagee elects
to permit Mortgagor to repair or restore the Premises following any damage or
injury to the Premises, or any part thereof, then the balance of such
compensation, awards, proceeds, damages, claims, insurance recoveries, rights of
action or payments shall be applied to the reimbursement of Mortgagor for
expenses incurred by it in such repair or restoration of the Premises, subject,
however, to the following conditions:

            (i) any such work of repair or restoration shall be of such a
      character as not to reduce, or otherwise adversely affect, the value of
      the buildings, improvements and fixtures on the Premises immediately
      before such damage or injury, nor to diminish the general utility of such
      buildings, improvements or fixtures for the purposes the same were used
      immediately prior to such damage;

<PAGE>

                                      11


            (ii) such work of repair or restoration shall be commenced as soon
      as reasonably possible after such damage or injury occurs and shall be
      completed by Mortgagor forthwith and with due diligence;

            (iii) such work of repair or restoration shall be done in accordance
      with plans, specifications and drawings submitted to and approved by
      Mortgagee;

            (iv) any such monies made available for such repair or restoration
      shall be disbursed in accordance with standard construction lending
      practices approved by Mortgagee or in any other manner approved by
      Mortgagee; and

            (v) in the event such compensation, awards, proceeds, damages,
      claims, insurance recoveries, rights of action or payments are
      insufficient to complete such repairs or restoration, Mortgagor shall
      provide the balance of the cost of such repairs or restoration. Any
      balance of monies held by Mortgagee and remaining after completion of such
      repair or restoration shall be applied to the payment or prepayment
      (without premium) of the indebtedness or liability secured hereby in such
      order as Mortgagee may determine.

            In the event Mortgagor does not elect to repair or restore the
Premises following any such damage or injury referred to herein, or if Mortgagor
elects to repair or restore the Premises but fails to comply with any of the
conditions hereinabove set forth, then all such compensation, awards, proceeds,
damages, claims, insurance recoveries, rights of action and payments, which
remain after the reimbursement of all costs and expenses of Mortgagee in
connection with recovery of the same, shall be applied, in the sole and absolute
discretion of Mortgagee and without regard to the adequacy of its security
hereunder, to the payment or prepayment (without premium) of the indebtedness or
liability secured hereby. Any application of such amounts or any portion thereof
to any indebtedness secured hereby shall not be construed to or waive any
default or notice of default hereunder or invalidate any act done pursuant to
any such default or notice.

            14. Right to Inspect. That Mortgagee and any persons authorized by
Mortgagee shall have the right to enter and inspect the Premises at all
reasonable times and, prior to an event of default hereunder, upon reasonable
notice; and that if, at any time after default by Mortgagor in the performance
of any of the terms, covenants or provisions of this Mortgage, the management or
maintenance of the Premises shall be determined by Mortgagee to be
unsatisfactory, Mortgagor shall employ, for the duration of such default, as
managing agent of the Premises, such person or firm as from time to time shall
be approved by Mortgagee. That Mortgagee and its designated agents shall have
the right to inspect Mortgagor's books and records with respect to the Premises
at all reasonable times.

<PAGE>

                                      12


            15. Financial Information. That Mortgagor, in addition to the
financial information required in the Credit Agreement, shall furnish to
Mortgagee as promptly as reasonably possible, such interim financial or other
information with respect to the operation of the Premises and with respect to
Mortgagor as Mortgagee may reasonably request. If Mortgagor shall have leased
all or substantially all of the Premises to another, such statements shall cover
the earnings and expenses in the latest fiscal year of the lessee under such
lease. In the case of such lease, if the lessee shall be an affiliate of
Mortgagor, Mortgagor will also furnish to Mortgagee the lessee's balance sheet
as of the end of the lessee's fiscal year and the lessee's statement of income
and surplus for such fiscal year, all in reasonable detail and stating in
comparative form the figures as of the end of and for the previous fiscal year,
and prepared, audited and reported upon by an independent certified public
accountant or, if permitted by Mortgagee, verified by an authorized financial
officer of the lessee.

            16. Assignment of Rents. That Mortgagor hereby assigns to Mortgagee
the rents, issues and profits of the Premises, together with all leases,
licenses and other documents evidencing such rents, issues and profits now or
hereafter in effect and any and all deposits held as security under said leases,
and shall, upon demand, deliver to Mortgagee an executed counterpart of each
such lease or other document. Nothing contained in the foregoing sentence shall
be construed to bind Mortgagee to the performance of any of the covenants,
conditions or provisions contained in any such lease or other document or
otherwise to impose any Paragraph 16 obligation on Mortgagee (including, without
limitation, any liability under the covenant of quiet enjoyment contained in any
lease in the event that any tenant shall have been joined as a party defendant
in any action to foreclose this Mortgage and shall have been barred and
foreclosed thereby of all right, title and interest and equity of redemption in
the Premises), except that Mortgagee shall be accountable for money actually
received pursuant to such assignment. Mortgagor hereby further grant to
Mortgagee the right (i) to enter upon and take possession of the Premises for
the purpose of collecting the said rents, issues and profits, (ii) to dispossess
by the usual summary proceedings any tenant defaulting in the payment thereof to
Mortgagee, (iii) to let the Premises, or any part thereof, and (iv) to apply
said rents, issues and profits, after payment of all necessary charges and
expenses, on account of said indebtedness. Such assignment and grant shall
continue in effect until all indebtedness secured by this Mortgage is fully and
finally paid, the execution of this Mortgage constituting and evidencing the
irrevocable consent of Mortgagor to the entry upon and taking possession of the
Premises by Mortgagee pursuant to such grant, whether foreclosure has been
instituted or not and without applying for a receiver. After an event of default
hereunder, Mortgagor shall be entitled to collect and receive the same until the
occurrence of a default by Mortgagor under any of the covenants, conditions or
agreements contained in this Mortgage. Mortgagor agrees to use said rents,
issues and profits in payment of principal and interest becoming due on this
Mortgage and in payment of taxes, assessments, water rates, sewer rents and
carrying charges becoming due against the Premises. Such rights of Mortgagor to
collect and receive said rents, issues and profits

<PAGE>

                                      13


may be revoked by Mortgagee upon any such default by Mortgagor, by giving
written notice of such revocation.

            17. Rents and Profits. That, in the event of any default under this
Mortgage, Mortgagor will pay monthly in advance to Mortgagee, on its entry into
possession pursuant to Article 16 hereof, or to any receiver appointed to
collect said rents, issues and profits, the fair and reasonable rental value for
the use and occupation of the Premises or of such part thereof as may be in the
possession of Mortgagor, and upon default in any such payment, will vacate and
surrender possession of the Premises or such part thereof, as the case may be,
to Mortgagee or to such receiver and, in default thereof, may be evicted by
summary proceedings or otherwise.

            18. Leases. (a) That Mortgagor has no right or power, as against
Mortgagee without its consent, to cancel, abridge or otherwise modify in any
material respect any of the leases or subleases now or hereafter affecting the
whole or any part of the Premises or any of the terms, provisions or covenants
thereof, or to accept prepayments of installments of rent to become due
thereunder and Mortgagor shall not do so without such consent.

            (b) That Mortgagor shall not enter into a lease of all or
substantially all of the Premises, unless (i) such lease shall expressly provide
that the leasehold estate created thereby shall be subject and subordinate to
all mortgages on the Premises and to the leasehold estates of subtenants created
by existing subleases, notwithstanding any clause in any such sublease
purporting to subordinate such sublease and the rights of the subtenant
thereunder to ground or underlying leases, (ii) such lease shall require that
each sublease thereafter made and each renewal of any existing sublease shall
provide that, (A) in the event of the termination of the underlying lease, the
sublease shall not terminate or be terminable by the subtenant, (B) in the event
of any action for the foreclosure of this Mortgage, the sublease shall not
terminate or be terminable by the subtenant by reason of the termination of the
underlying lease unless the subtenant is specifically named and joined in any
such action and unless a judgment is obtained therein against the subtenant and
(C) in the event that the underlying lease is terminated as aforesaid, the
subtenant shall attorn to the lessor under the underlying lease or to the
purchaser at the sale of the Premises on such foreclosure, as the case may be,
and (iii) the lessee in such lease shall agree, and be authorized by Mortgagor,
to direct and require the subtenants and other occupants of space in the
Premises to pay to Mortgagee on its entry into possession pursuant to Article 16
hereof, or to a receiver appointed to collect the rents, issues and profits of
the Premises, the rents payable by them under the terms of their subleases or
occupancy agreements upon being notified by Mortgagee of any default under this
Mortgage and of Mortgagee's entry into possession of the Premises, or of the
appointment of any such receiver, with the same force and with like effect as if
said lease had not been entered into and Mortgagor were entitled to receive the
said space rents directly.

<PAGE>

                                      14


            19. Lease Assurances. That upon notice and demand, Mortgagor shall,
from time to time, execute, acknowledge and deliver or cause to be executed,
acknowledged and delivered to Mortgagee, in form satisfactory to Mortgagee, one
or more separate assignments (confirmatory of the general assignment provided in
Article 16 hereof) of the lessor's interest in any lease or sublease now or
hereafter affecting the whole or any part of the Premises and which shall also
restrict Mortgagor's right or power, as against Mortgagee, without its consent,
to cancel, abridge or otherwise modify, or accept prepayments of installments of
rent to become due under, any such lease or sublease; that Mortgagor shall pay
to Mortgagee the expenses incurred by Mortgagee in connection with the
preparation and recording of any such instrument; that Mortgagor will (i)
fulfill or perform each and every condition and covenant of each such lease or
sublease to be fulfilled or performed by the lessor thereunder, (ii) give prompt
notice to Mortgagee of any notice of default by the lessor thereunder received
by Mortgagor together with a complete copy of any such notice, and (iii)
enforce, short of termination thereof, the performance or observance of each and
every covenant and condition thereof by the lessee thereunder to be performed or
observed.

            20. Default. The following shall constitute events of default
hereunder:

            (a) failure in the due and punctual payment of any indebtedness or
      performance of any obligations secured hereunder, including any principal
      or interest or any other amounts required to be paid or due or to become
      due under this Mortgage, the Credit Agreement, or under any other
      agreement(s) or instrument(s) now or hereafter securing the indebtedness
      which is also secured hereunder; or

            (b) non-payment of any tax, water rate, sewer rent, assessment or
      for twenty (20) days after the same first becomes due and payable; or if
      Mortgagor fails to furnish Mortgagee with receipted tax bills or other
      proof of payment of the aforesaid items by no later than thirty (30) days
      after the dates on which such items must be paid so as not to constitute a
      default hereunder; or

            (c) breach, after notice and demand, either in Mortgagor's
      responsibility for assigning and delivering the policies of insurance
      herein described or referred to, or in reimbursing Mortgagee for premiums
      paid on such insurance, as hereinbefore provided; or

            (d) the actual or threatened material waste, removal or demolition
      of any building or other property on the Premises, except as permitted by
      Article 3 after thirty (30) days notice to Mortgagor and its failure to
      cure; or

            (e) assignment by Mortgagor of the whole or any part of the rents,
      issues or profits arising from the Premises to any person without the
      written consent of Mortgagee; or

<PAGE>

                                      15


            (f) if the buildings on the Premises are not maintained in
      reasonably good repair in any material respect after thirty (30) days'
      notice to Mortgagor and its failure to cure; or

            (g) failure to comply in any material respect with any requirement
      or order or notice of violation of law or ordinance issued by any
      governmental department claiming jurisdiction over the Premises within
      thirty (30) days from the issuance thereof; or

            (h) if, on application of Mortgagee, two or more fire insurance
      companies lawfully doing business in the State of New Jersey refuse to
      issue policies insuring the buildings on the Premises; or

            (i) if Mortgagor shall fail to make payment of any other sums
      required to be paid hereunder within the period required by specific
      provision of this Mortgage or, if no such period is so provided, by not
      later than ten (10) days after written notice; or

            (j) if, without the prior consent of Mortgagee, the Premises or any
      interest therein shall be sold, pledged, hypothecated, contracted to be
      sold, leased with an option to purchase, conveyed, alienated or otherwise
      disposed of or transferred or further encumbered for debt by Mortgagor; or

            (k) if a lien for the performance of work or the supply of materials
      is filed against the Premises or any portion thereof which shall not be
      discharged or bonded within thirty (30) days from the filing thereof; or

            (l)   if an Event of Default shall occur under the Credit Agreement.

            21. Remedies. Upon any default under paragraph 20, without notice or
presentment, each of which are hereby waived by Mortgagor, and without waiving
any rights and/or remedies Mortgagee may now or hereafter have under or in
connection with the Credit Agreement and under or in connection with any other
agreements Mortgagee may now or hereafter have with or concerning Mortgagor,
Mortgagee shall have the right to and may:

            (a) declare the entire principal of all indebtedness secured
      hereunder then outstanding (if not then due and payable), and all accrued
      and unpaid interest thereon, and all other sums connected therewith, to be
      due and payable immediately, and upon any such declaration all
      indebtedness secured hereunder and said accrued and unpaid interest and
      other sums shall become and be immediately due and payable, anything in
      any of the Loan Documents or in this Mortgage to the contrary
      notwithstanding;

<PAGE>

                                      16


            (b) personally, or by its agents or attorneys, may enter into and
      upon all or any part of the Premises, and each and every part thereof,
      with or without force and with or without process of law and may exclude
      Mortgagor, its agents and servants wholly therefrom and from having and
      holding the same, may use, operate, manage and control the Premises or any
      part thereof and all records, documents, leases, books, papers and
      accounts of Mortgagor relating thereto and conduct the business thereof,
      either personally or by its superintendents, managers, agents, servants,
      attorneys or receivers; and likewise, from time to time, at the expense of
      Mortgagor, Mortgagee may make all necessary or proper repairs, renewals
      and replacements and such useful alterations, additions, betterments and
      improvements thereto and thereon as to it may seem advisable; and in every
      such case Mortgagor shall, at any time, or times, upon demand of Mortgagee
      forthwith surrender possession of the Premises and Mortgagee shall have
      the right to manage and operate the Premises and to carry on the business
      thereof and exercise all rights and powers of Mortgagor with respect
      thereto either in the name of Mortgagor or otherwise as it shall deem
      best; and Mortgagee shall be entitled to collect and receive all gross
      receipts, earnings, revenues, rents, issues, profits and income of the
      Mortgaged Property and every part thereof, all of which shall for all
      purposes constitute property of Mortgagee; and after deducting the
      expenses of conducting the business thereof and of all maintenance,
      repairs, renewals, replacements, alterations, additions, betterments and
      improvements and amounts necessary to pay for taxes, assessments,
      insurance and prior or other proper charges upon the Premises or any part
      thereof, as well as just and reasonable compensation for the services of
      Mortgagee and for all attorneys, counsel, agents, clerks, servants and
      other employees by it properly engaged and employed, Mortgagee may apply
      the monies arising as aforesaid in such manner, in such order and at such
      times as Mortgagee shall determine in its discretion to the payment of any
      indebtedness secured hereby and the interest thereon, when and as the same
      shall become payable and/or to the payment of any other sums required to
      be paid by Mortgagor under this Mortgage;

            (c) (i) with or without entry, personally or by its agents or
      attorneys, insofar as applicable, sell the Premises, including, without
      limitation, the Building Equipment or any part thereof to the extent
      permitted and pursuant to the procedures provided by law, and all estate,
      right, title and interest, claim and demand therein, and right of
      redemption thereof, at one or more sales as a single entity or in parcels,
      and at such time and place, upon such terms and after such notice thereof
      as may be required or permitted by law;

            (ii) institute an action of judicial foreclosure on this Mortgage or
      institute other proceedings according to law for the foreclosure hereof or
      otherwise as may be allowed, at law or in equity, and may prosecute the
      same to judgment, execution and sale for the collection of all of the
      obligations secured hereby, and all interest with



<PAGE>

                                      17


      respect thereto, together with all taxes and insurance premiums advanced
      by Mortgagee and other sums payable by Mortgagor hereunder, and all fees,
      costs and expenses of such proceedings, including reasonable attorneys'
      fees and expenses;

            (iii) take such steps to protect and enforce its rights, whether by
      action, suit or proceeding in equity or at law, for the specific
      performance of any covenant, condition or agreement in the Credit
      Agreement and/or in this Mortgage or in aid of the execution of any power
      herein or therein granted, or for any foreclosure hereunder, or for the
      enforcement of any other appropriate legal or equitable remedy or
      otherwise as Mortgagee shall elect;

            (iv) exercise in respect of the Premises consisting of personal
      property or fixtures, or both, all of the rights and remedies available to
      a secured party upon default under the applicable provisions of the
      Uniform Commercial Code in effect in the State of New Jersey; and

            (v) exercise any or all other rights and remedies afforded Mortgagee
      under the Loan Documents, or at law or in equity.

            (d) (i) Mortgagee may adjourn from time to time any sale by it to be
      made under or by virtue of this Mortgage by announcement at the time and
      place appointed for such sale or for such adjourned sale or sales; and,
      except as otherwise provided by any applicable provision of law,
      Mortgagee, without further notice or publication, may make such sale at
      the time and place to which the same shall be so adjourned.

            (ii) Upon any sale, it shall not be necessary for Mortgagee or any
      public officer acting under execution or order of court to have present or
      constructive possession of any of the Premises.

            (iii) The recitals contained in any conveyance made by Mortgagee to
      any purchaser at any sale made pursuant hereto or under applicable law
      shall be full evidence of the matters therein stated, and all
      prerequisites to such sale shall be presumed to have been satisfied and
      performed.

            (iv) To the extent permitted by law, any such sale or sales made
      under or by virtue of this Mortgage, or under or by virtue of any judicial
      proceedings, shall operate to divest all estate, right, title, interest,
      claim and demand whatsoever, either at law or in equity, of Mortgagor in
      and to the interest, rights, premises and property sold, and shall be a
      perpetual bar, both at law and in equity, against Mortgagor, their
      respective successors and assigns, and against any and all persons or
      entities claiming

<PAGE>

                                      18


      the premises and property sold, or any part thereof, from, through or
      under Mortgagor and their respective successors or assigns.

            (v) The receipt of Mortgagee for the purchase money paid at any such
      sale, or the receipt of any other person authorized to receive the same,
      shall be sufficient discharge therefor to any purchaser of the property,
      or any part thereof, sold as aforesaid, and no such purchaser, or his
      representatives, grantees or assigns, after paying such purchase money and
      receiving such receipt, shall be bound to see to the application of such
      purchase money or any part thereof upon or for any trust or purpose of
      this Mortgage, or be liable for misapplication or nonapplication of any
      such purchase money, or any part thereof, or be bound to inquire as to the
      authorization, necessity, expediency or regularity of any such sale.

            (vi) In case the liens or security interests hereunder, or by the
      exercise of any other right or power, shall be foreclosed by Mortgagee's
      sale or by other judicial action, the purchaser at any such sale shall
      receive, as an incident to his ownership, immediate possession of the
      property purchased, and if Mortgagor or its respective successors shall
      hold possession of said property, or any part thereof, subsequent to
      foreclosure, Mortgagor or its respective successors shall be considered as
      tenants at sufferance of the purchaser at foreclosure sale, and anyone
      occupying the property after demand made for possession thereof shall be
      guilty of forcible detainer and shall be subject to eviction and removal,
      forcible or otherwise, with or without process of law, and all damages by
      reason thereof are hereby expressly waived.

            (vii) In the event a foreclosure hereunder shall be commenced by
      Mortgagee, Mortgagee may at any time before the sale abandon the suit, and
      may then institute suit for the collection of amounts due or to become due
      under the Credit Agreement and for the foreclosure of the liens and
      security interest hereof. If Mortgagee should institute a suit for the
      collection of amounts due or to become due under the Credit Agreement and
      for a foreclosure of the liens and security interest hereof, it may at any
      time before the entry of a final judgment in said suit dismiss the same
      and proceed to sell the Premises, or any part thereof, in accordance with
      provisions of this Mortgage.

            (viii) Should any default occur hereunder, any reasonable expenses
      incurred by Mortgagee in consulting, negotiating, prosecuting, resettling
      or settling the claim of Mortgagee, including, without limitation,
      reasonable attorneys' fees and disbursements, shall become an additional
      obligation of Mortgagor hereunder.

            (ix) In the event of any sale made under or by virtue of this
      Mortgage the entire principal of, interest on, and all other indebtedness
      secured hereunder, if not previously due and payable, immediately
      thereupon shall, anything in the Credit

                                      19


      Agreement or in this Mortgage to the contrary notwithstanding, become due
      and payable.

            (x) The purchase money proceeds or avails of any sale made under or
      by virtue of this Mortgage, together with any other sums which then may be
      held by Mortgagee under this Mortgage, whether under the provisions hereof
      or otherwise, shall be applied in accordance with the applicable law and,
      to the extent not inconsistent therewith, as follows:

                  First: To the payment of the reasonable costs and expenses of
            such sale, including reasonable compensation to Mortgagee, its
            agents and counsel, and of any judicial proceedings wherein the same
            may be made, and of all expenses, liabilities and advances made or
            incurred by Mortgagee under this Mortgage, including without
            limitation any such expenses, liabilities and/or advances to remedy
            default by Mortgagor, or to otherwise establish, preserve or enforce
            any rights hereunder, together with interest at the rate set forth
            in Article 4 on all advances made by Mortgagee and all taxes or
            assessments, except any taxes, assessments or other charges subject
            to which the Premises shall have been sold.

                  Second: To the payment of the whole amount then due, owing or
            unpaid upon indebtedness secured hereunder in accordance with the
            provisions of the Credit Agreement, including, without limitation,
            all principal and interest due and to become due under or in
            connection with the Credit Agreement, with interest on the unpaid
            principal at the rate set forth in Article 4 from and after the
            happening of any event of default described in paragraph 20, from
            the due date of any such payment of principal until the same is
            paid.

                  Third: To the payment of any other sums required to be paid by
            Mortgagor pursuant to any provision of this Mortgage or the Credit
            Agreement, all with interest at the rate set forth in Article 4,
            from the date such sums were or are required to be paid under this
            Mortgage.

                  Fourth: To the payment of the surplus, if any, to whomsoever
            may be lawfully entitled to receive the same.

            (xi) Upon any sale made under or by virtue of this Mortgage, by
      virtue of judicial proceedings or of a judgment or decree of foreclosure
      and sale, Mortgagee may bid for and acquire the Premises or any part
      thereof and in lieu of paying cash therefor, and upon compliance with the
      terms of said sale, may hold, retain and dispose of such property without
      further accountability therefor. Mortgagee may also make settlement for
      the purchase price by crediting upon the indebtedness of

<PAGE>

                                      20


      Mortgagor secured by this Mortgage the net sales price after deducting
      therefrom the expense of the sale and the costs of the action and any
      other sums which Mortgagee is authorized to deduct under this Mortgage.

            22. Non-Waiver by Mortgagee. That any failure by Mortgagee to insist
upon the strict performance by Mortgagor of any of the terms and provisions
hereof shall not be deemed to be a waiver of any of the terms and provisions
hereof, and Mortgagee, notwithstanding any such failure, shall have the right
thereafter to insist upon the strict performance by Mortgagor of any and all of
the terms and provisions of this Mortgage to be performed by Mortgagor; that
neither Mortgagor nor any other person now or hereafter obligated for the
payment of the whole or any part of the sums now or hereafter secured by this
Mortgage shall be relieved of such obligation by reason of the failure of
Mortgagee to comply with any request of Mortgagor, or of any other person so
obligated, to take action to foreclose this Mortgage or otherwise enforce any of
the provisions of this Mortgage or any obligations secured by this Mortgage, or
by reason of the release, regardless of consideration, of the whole or any part
of the security held for the indebtedness secured by this Mortgage, or by reason
of any agreement or stipulation between any subsequent owner or owners of the
Premises and Mortgagee extending the time of payment or modifying the terms of
any indebtedness secured hereunder or this Mortgage without first having
obtained the consent of Mortgagor or such other person, and in the latter event,
Mortgagor and all such other persons shall continue liable to make such payments
according to the terms of any such agreement of extension or modification unless
expressly released and discharged in writing by Mortgagee; that, regardless of
consideration and without the necessity for any notice to or consent by the
holder of any subordinate lien on the Premises, Mortgagee may release the
obligation of anyone at any time liable for any of the indebtedness secured by
this Mortgage or any part of the security held for the indebtedness without, as
to the security or the remainder thereof, in any way impairing or affecting the
lien hereof or the priority thereof over any subordinate encumbrance; and that
Mortgagee may resort for the payment of the indebtedness secured hereby to any
other security therefor held by Mortgagee in such order and manner as Mortgagee
may elect.

            23. Taxation of Mortgagee or Indebtedness. That if at any time the
United States of America, any state thereof or any department, agency, bureau or
governmental subdivision thereof, having jurisdiction, shall require revenue
stamps to be affixed to any indebtedness secured hereunder, or other tax paid on
or in connection therewith, Mortgagor will pay the same with any interest or
penalties imposed in connection therewith.

            24. Building Equipment, Fixtures and Personal Property. That
Mortgagor shall execute any and all such documents, including Financing
Statements pursuant to the Uniform Commercial Code of the State of New Jersey as
Mortgagee may request, to preserve and maintain the priority of the lien created
hereby on property which may be deemed personal property or fixtures, and
Mortgagor shall pay to Mortgagee on demand any

<PAGE>

                                      21


expenses incurred by Mortgagee in connection with the preparation, execution and
filing of any such documents. Mortgagor hereby authorizes and empowers Mortgagee
to execute and file, on Mortgagor's behalf, all Financing Statements, and
refilings and continuations thereof as Mortgagee deems necessary or advisable to
create, preserve and protect the lien granted to Mortgagee herein. When and if
Mortgagor and Mortgagee shall respectively become Debtor and Secured Party in
any Uniform Commercial Code Financing Statement affecting Building Equipment or
other property referred to or described herein, this Mortgage shall be deemed
the Security Agreement as defined in said Uniform Commercial Code and the
remedies for any violation of the covenants, terms and conditions of the
agreements herein contained shall be (i) as prescribed herein, (ii) by general
law or (iii) as to such part of the security which is also reflected in said
Financing Statement, by the specific statutory consequences now or hereafter
enacted and specified in said Uniform Commercial Code, all at Mortgagee's sole
election. The filing of such a Financing Statement in the records normally
having to do with personal property shall never be construed as in any way
derogating from or impairing this declaration and hereby stated intention of the
parties hereto, that all items of Building Equipment and other property used in
connection with the production of income from the Premises (furniture only
excepted) or adapted for use therein or which are described or reflected in this
Mortgage are, and at all times and for all purposes and in all proceedings, both
legal and equitable, shall be, regarded as part of the real estate irrespective
of whether or not (i) any such item is physically attached to the improvement,
serial numbers are used for the better identification of certain equipment items
capable of being thus identified in a recital contained herein or in any list
filed with Mortgagee or (iii) any such item is referred to or reflected in any
such Financing Statement so filed at any time. Similarly, the mention in any
such Financing Statement of (1) the rights in or the proceeds of any fire and/or
hazard insurance policy, (2) any award in eminent domain proceedings for a
taking or for loss of value or (3) the debtor's interest as lessor in any
present or future lease or rights to income growing out of the use or occupancy
of the Premises, whether pursuant to a lease or otherwise, shall never be
construed as in any way altering any of the rights of Mortgagee as determined by
this instrument or impugning the priority of Mortgagee's lien granted hereby or
by any other recorded document, but such mention in the Financing Statement is
declared to be for the protection of Mortgagee in the event any court or judge
shall at any time hold with respect to (1), (2) or (3) that notice of
Mortgagee's priority of interest, to be effective against a particular class of
persons, including but not limited to the Federal government and any
subdivisions or entity of the Federal government, must be filed in the Uniform
Commercial Code records.

            25. Certain Waivers. That Mortgagor will not at any time insist
upon, or plead, or in any manner whatever claim or take any benefit or advantage
of any stay or extension or moratorium law, any exemption from execution or sale
of the Premises or any part thereof, wherever enacted, now or at any time
hereafter in force, which may affect the covenants and terms of performance of
this Mortgage, nor claim, take or insist upon any benefit or advantage of any
law now or hereafter in force providing for the valuation or

<PAGE>

                                      22


appraisal of the Premises or any part thereof, prior to any sale or sales
thereof which may be made pursuant to any provision herein, or pursuant to the
decree, judgment or order of any court of competent jurisdiction; nor, after any
such sale or sales, claim or exercise any right under any statute heretofore or
hereafter enacted to redeem the property so sold or any part thereof and
Mortgagor hereby expressly waives all benefit or advantage of any such law or
laws and covenants not to hinder, delay or impede the execution of any power
herein granted or delegated to Mortgagee, but to suffer and permit the execution
of every power as though no such law or laws had been made or enacted.
Mortgagor, for itself and all who may claim under it, waives, to the extent that
it lawfully may, all right to have the Premises marshaled upon any foreclosure
hereof.

necessary steps to obtain any necessary permits governing the use, storage and
disposal of such substances and has made adequate arrangements to use, store and
dispose of such substances safely.

            " -.2 Notices. If Tenant receives any notice of the happening of any
event involving the use, spill, discharge or cleanup of any Hazardous Substance,

      premises (which may be given in any oral or written form, provided same is
      followed with all due dispatch by written notice given by certified mail,
      return receipt requested) within three (3) business days of the time
      Tenant first receives notice of such Hazardous Discharge or Environmental
      Complaint; or

            "(b) If the DEP, EPA, or any other local, state or federal agency
      asserts or creates a lien upon any or all of the demised premises by
      reason of the occurrence of a Hazardous Discharge or an Environmental
      Complaint or otherwise; or

            "(c) If the DEP, EPA or any other local, state or federal agency
      asserts a claim against the Tenant, the demised premises or Landlord for
      damages or cleanup costs related to a Hazardous Discharge or an
      Environmental Complaint on or pertaining to the demised premises;

            has commenced and is diligently pursuing either: (x) cure or
            correction of the event which constitutes the basis for the claim,

            bond, letter of credit or other security satisfactory in form,
            substance and amount to Landlord and the agency or entity asserting
            the claim to secure the proper and complete cure or correction of

      Landlord's satisfaction expressed in writing, Tenant's obligations under
      this subparagraph ____.5(b) shall cease.

            " -.8 Performance by Landlord. In the event of Tenant's failure to
comply in full with this Article, Landlord may, at its option, perform any or

rules regulations and orders including, without limitation, Environmental Laws,

statute; or (ii) the use or proposed use of the Premises as a "Major Facility".

Mortgagee as a result of any violation of an Environmental Law by Mortgagor or
in respect of the Premises.

                              SUBSIDIARY GUARANTY

            Subsidiary Guaranty dated October 1, 1996 made by the parties listed
on the signature pages hereof (each such party, a "Subsidiary Guarantor"), in
favor of the Secured Parties (as defined in the Credit Agreement referred to
below).

            PRELIMINARY STATEMENT. The Lender Parties, Banque Nationale de
Paris, as Administrative Agent and as Initial Issuing Bank, and NationsBank
N.A., as Documentation Agent, are parties to a Credit Agreement dated as of
October 1, 1996 (said Agreement, as it may hereafter be amended, supplemented or
otherwise modified from time to time, being the "Credit Agreement", the terms
defined therein and not otherwise defined herein being used herein as therein
defined) with MEDIQ/PRN Life Support Services, Inc., a Delaware corporation (the
"Borrower"), MEDIQ Incorporated, a Delaware corporation ("MEDIQ") and PRN
Holdings, Inc., a Delaware corporation ("Holdings", and, together with MEDIQ,
the "Parent Guarantors"). Each Subsidiary Guarantor may receive a portion of the
proceeds of the Advances under the Credit Agreement and will derive substantial
direct and indirect benefit from the transactions contemplated by the Credit
Agreement. It is a condition precedent to the making of Advances and the
issuance of Letters of Credit by the Lender Parties under the Credit Agreement
and the entry by the Hedge Banks into Bank Hedge Agreements with the Borrower
from time to time that each Subsidiary Guarantor shall have executed and
delivered this Subsidiary Guaranty.

            NOW, THEREFORE, in consideration of the premises and in order to
induce the Lender Parties to make Advances and to issue Letters of Credit under
the Credit Agreement, each Subsidiary Guarantor, jointly and severally with each
other Subsidiary Guarantor, hereby agrees as follows:

            Section 1. Subsidiary Guaranty; Limitation of Liability. (a) Each
Subsidiary Guarantor hereby absolutely, unconditionally and irrevocably
guarantees the punctual payment when due, whether at stated maturity, by
acceleration or otherwise, of all Obligations of each other Loan Party now or
hereafter existing under the Loan Documents, whether for principal, interest,
fees, expenses or otherwise (such Obligations being the "Guaranteed
Obligations"), and agrees to pay any and all reasonable expenses (including
counsel fees and expenses) incurred by the Administrative Agent or any other
Secured Party in enforcing any rights under this Subsidiary Guaranty or any
other Loan Document. Without limiting the generality of the foregoing, each
Subsidiary Guarantor's liability shall extend to all amounts that constitute
part of the Guaranteed Obligations and would be owed by any other Loan Party to
the Administrative Agent or any other Secured Party under the Loan Documents but
for the fact that they are unenforceable or not allowable due to the existence
of a bankruptcy, reorganization or similar proceeding involving such Loan Party.

            (b) (i) Each Subsidiary Guarantor and by its acceptance of this
      Subsidiary Guaranty, the Administrative Agent and each other Secured
      Party, hereby

<PAGE>

                                      2


      confirms that it is the intention of all such parties that this Subsidiary
      Guaranty not constitute a fraudulent transfer or conveyance for purposes
      of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
      Fraudulent Transfer Act or any similar federal or state law to the extent
      applicable to this Subsidiary Guaranty. To effectuate the foregoing
      intention, the Administrative Agent, the other Secured Parties and the
      Subsidiary Guarantors hereby irrevocably agree that the Obligations of
      each Subsidiary Guarantor under this Subsidiary Guaranty shall not exceed
      the greater of (A) the net benefit realized by such Subsidiary Guarantor
      from the proceeds of the Advances made from time to time by the Borrower
      to such Subsidiary Guarantor or any subsidiary of such Subsidiary
      Guarantor and (B) the maximum amount that will, after giving effect to
      such maximum amount and all other contingent and fixed liabilities of such
      Subsidiary Guarantor that are relevant under such laws, and after giving
      effect to any collections from, rights to receive contribution from or
      payments made by or on behalf of any other Subsidiary Guarantor in respect
      of the Obligations of such other Subsidiary Guarantor under this
      Subsidiary Guaranty, result in the Obligations of such Subsidiary
      Guarantor under this Subsidiary Guaranty not constituting a fraudulent
      transfer or conveyance. For purposes hereof, "Bankruptcy Law" means Title
      11, U.S. Code, or any similar Federal or state law for the relief of
      debtors.

            (ii) Each Subsidiary Guarantor agrees that in the event any payment
      shall be required to be made to the Secured Parties under this Subsidiary
      Guaranty or any other guaranty, such Subsidiary Guarantor will contribute,
      to the maximum extent permitted by law, such amounts to each other
      Subsidiary Guarantor and each other guarantor so as to maximize the
      aggregate amount paid to the Secured Parties under the Loan Documents.

            Section 2. Subsidiary Guaranty Absolute. Each Subsidiary Guarantor
guarantees that the Guaranteed Obligations will be paid strictly in accordance
with the terms of the Loan Documents, regardless of any law, regulation or order
now or hereafter in effect in any jurisdiction affecting any of such terms or
the rights of the Administrative Agent or any other Secured Party with respect
thereto. The Obligations of each Subsidiary Guarantor under this Subsidiary
Guaranty are independent of the Guaranteed Obligations or any other Obligations
of any other Loan Party under the Loan Documents, and a separate action or
actions may be brought and prosecuted against such Subsidiary Guarantor to
enforce this Subsidiary Guaranty, irrespective of whether any action is brought
against the Borrower or any other Loan Party or whether the Borrower or any
other Loan Party is joined in any such action or actions. The liability of each
Subsidiary Guarantor under this Subsidiary Guaranty shall be irrevocable,
absolute and unconditional irrespective of, and each Subsidiary Guarantor hereby
irrevocably waives any defenses it may now or hereafter have in any way relating
to, any or all of the following:

            (a) any lack of validity or enforceability of any Loan Document or
      any agreement or instrument relating thereto;

            (b) any change in the time, manner or place of payment of, or in any
      other term of, all or any of the Guaranteed Obligations or any other
      Obligations of any other Loan Party under the Loan Documents, or any other
      amendment or waiver of or any consent to departure from any Loan Document,
      including, without limitation, any increase in the Guaranteed Obligations
      resulting from the extension of additional credit to any Loan Party or any
      of its Subsidiaries or otherwise;

            (c) any taking, exchange, release or non-perfection of any
      Collateral, or any taking, release or amendment or waiver of or consent to
      departure from any other guaranty, for all or any of the Guaranteed
      Obligations;

            (d) any manner of application of Collateral, or proceeds thereof, to
      all or any of the Guaranteed Obligations, or any manner of sale or other
      disposition of any Collateral for all or any of the Guaranteed Obligations
      or any other Obligations of any other Loan Party under the Loan Documents
      or any other assets of any Loan Party or any of its Subsidiaries;

            (e) any change, restructuring or termination of the corporate
      structure or existence of any Loan Party or any of its Subsidiaries; or

            (f) any other circumstance (including, without limitation, any
      statute of limitations) or any existence of or reliance on any
      representation by the Administrative Agent or any other Secured Party that
      might otherwise constitute a defense available to, or a discharge of, the
      Borrower, any Subsidiary Guarantor or any other guarantor or surety.

This Subsidiary Guaranty shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Guaranteed Obligations is
rescinded or must otherwise be returned by any Secured Party or any other Person
upon the insolvency, bankruptcy or reorganization of the Borrower or any other
Loan Party or otherwise, all as though such payment had not been made.

            Section 3. Waiver. (a) Each Subsidiary Guarantor hereby waives
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Guaranteed Obligations and this Subsidiary Guaranty and any
requirement that the Administrative Agent, or any other Secured Party protect,
secure, perfect or insure any Lien or any property subject thereto or exhaust
any right or take any action against any Loan Party or any other Person or any
collateral. Each Subsidiary Guarantor acknowledges that it will receive direct
and indirect benefits from the financing arrangements contemplated by the


<PAGE>

                                      4


Loan Documents and that the waiver set forth in this Section 3 is knowingly made
in contemplation of such benefits.

            Section 4. Subrogation. No Subsidiary Guarantor will exercise any
rights that it may now or hereafter acquire against the Borrower or any other
insider guarantor that arise from the existence, payment, performance or
enforcement of such Subsidiary Guarantor's Obligations under this Subsidiary
Guaranty or any other Loan Document, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any
right to participate in any claim or remedy of the Administrative Agent or any
other Secured Party against the Borrower or any other insider guarantor or any
collateral, whether or not such claim, remedy or right arises in equity or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Borrower or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim, remedy or right, unless and until
all of the Obligations and all other amounts payable under this Subsidiary
Guaranty shall have been paid in full in cash and the Commitments shall have
expired or terminated. If any amount shall be paid to any Subsidiary Guarantor
in violation of the preceding sentence at any time prior to the later of the
payment in full in cash of the Guaranteed Obligations and all other amounts
payable under this Subsidiary Guaranty and the Termination Date, such amount
shall be held in trust for the benefit of the Administrative Agent and the other
Secured Parties and shall forthwith be paid to the Administrative Agent to be
credited and applied to the Guaranteed Obligations and all other amounts payable
under this Subsidiary Guaranty, whether matured or unmatured, in accordance with
the terms of the Loan Documents, or to be held as collateral for any Guaranteed
Obligations or other amounts payable under this Subsidiary Guaranty thereafter
arising. If (i) any Subsidiary Guarantor shall make payment to the
Administrative Agent or any other Secured Party of all or any part of the
Guaranteed Obligations, (ii) all of the Guaranteed Obligations and all other
amounts payable under this Subsidiary Guaranty shall be paid in full in cash and
(iii) the Termination Date shall have occurred, the Administrative Agent and the
other Secured Parties will, at such Subsidiary Guarantor's request and expense,
execute and deliver to such Subsidiary Guarantor appropriate documents, without
recourse and without representation or warranty, necessary to evidence the
transfer by subrogation to such Subsidiary Guarantor of an interest in the
Guaranteed Obligations resulting from such payment by such Subsidiary Guarantor.

            Section 5. Payments Free and Clear of Taxes, Etc. (a) Any and all
payments by any Subsidiary Guarantor hereunder shall be made, in accordance with
Section 2.11 of the Credit Agreement, free and clear of and without deduction
for any and all present or future Taxes. If any Subsidiary Guarantor shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to the Administrative Agent or any other Secured Party, (i) the sum
payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums



<PAGE>

                                      5


payable under this Section) the Administrative Agent or such other Secured Party
(as the case may be) receives an amount equal to the sum it would have received
had no such deductions been made, (ii) such Subsidiary Guarantor shall make such
deductions and (iii) such Subsidiary Guarantor shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with applicable law.

            (b) In addition, each Subsidiary Guarantor agrees to pay any present
or future Other Taxes.

            (c) Each Subsidiary Guarantor shall indemnify the Administrative
Agent and each other Secured Party for and hold it harmless against the full
amount of Taxes and Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section)
paid by the Administrative Agent or such other Secured Party (as the case may
be) and any liability (including penalties, additions to tax, interest and
expenses) arising therefrom or with respect thereto. This indemnification shall
be made within 30 days from the date the Administrative Agent or such other
Secured Party (as the case may be) makes written demand therefor.

            (d) Within 30 days after the date of any payment of Taxes, such
Subsidiary Guarantor shall furnish to the Administrative Agent, at its address
referred to in Section 9.02 of the Credit Agreement, the original or a certified
copy of a receipt evidencing such payment. If no Taxes are payable in respect of
any payment hereunder by any Subsidiary Guarantor through an account or branch
outside the United States or by or on behalf of such Subsidiary Guarantor by a
payor that is not a United States person, such Subsidiary Guarantor shall
furnish, or shall cause such payor to furnish, to the Administrative Agent, a
certificate from each appropriate taxing authority or authorities, or an opinion
of counsel acceptable to the Administrative Agent, in either case stating that
such payment is exempt from or not subject to Taxes. For purposes of this
subsection (d) and subsection (e), the terms "United States" and "United States
person" shall have the meanings specified in Section 7701 of the Internal
Revenue Code.

            (e) Without prejudice to the survival of any other agreement of any
Subsidiary Guarantor hereunder, the agreements and obligations of each
Subsidiary Guarantor contained in this Section 5 shall survive the payment in
full of the Guaranteed Obligations and all other amounts payable under this
Subsidiary Guaranty.

            Section 6. Representations and Warranties. Each Subsidiary Guarantor
hereby represents and warrants as follows:

            (a) Such Subsidiary Guarantor (i) is a corporation duly organized,
      validly existing and in good standing under the laws of the jurisdiction
      of its incorporation, (ii) is duly qualified and in good standing as a
      foreign corporation in each other



<PAGE>

                                      6


      jurisdiction in which it owns or leases property or in which the conduct
      of its business requires it to so qualify or be licensed except where the
      failure to so qualify or be licensed is not reasonably likely to have a
      Material Adverse Effect and (iii) has all requisite corporate power and
      authority (including, without limitation, all governmental licenses,
      permits and other approvals) to own or lease and operate its properties
      and to carry on its business as now conducted and as proposed to be
      conducted. All of the outstanding Capital Stock of such Subsidiary
      Guarantor has been validly issued, is fully paid and non-assessable and
      each Subsidiary Guarantor is owned by a Loan Party, free and clear of all
      Liens, except those created under the Loan Documents.

            (b) The execution, delivery and performance by such Subsidiary
      Guarantor of this Subsidiary Guaranty are within such Subsidiary
      Guarantor's corporate powers, have been duly authorized by all necessary
      corporate action, and do not (i) contravene such Subsidiary Guarantor's
      charter or bylaws, (ii) violate any law (including, without limitation,
      the Securities Exchange Act of 1934 and the Racketeer Influences and
      Corrupt Organizations Chapter of the Organized Crime Control Act of 1970),
      rule, regulation (including, without limitation, Regulation X of the Board
      of Governors of the Federal Reserve System), order, writ, judgment,
      injunction, decree, determination or award, (iii) conflict with or result
      in the breach of, or constitute a default under, any loan agreement,
      contract, indenture, mortgage, deed of trust, lease or other instrument
      binding on or affecting such Subsidiary Guarantor, any of its Subsidiaries
      or any of its or their properties or (iv) except for the Liens created
      under the Loan Documents, result in or require the creation or imposition
      of any Lien upon or with respect to any of the properties of such
      Subsidiary Guarantor or any of its Subsidiaries. Neither such Subsidiary
      Guarantor nor any of its Subsidiaries is in violation of any such law,
      rule, regulation, order, writ, judgment, injunction, decree, determination
      or award or in breach of any such contract, loan agreement, indenture,
      mortgage, deed of trust, lease or other instrument, the violation or
      breach of which is reasonably likely to have a Material Adverse Effect.

            (c) No authorization or approval or other action by, and no notice
      to or filing with, any governmental authority or regulatory body or any
      other third party is required for (i) the due execution, delivery,
      recordation, filing or performance by such Subsidiary Guarantor of this
      Subsidiary Guaranty or any other Loan Document to which such Subsidiary
      Guarantor is a party and (ii) the exercise by the Administrative Agent or
      any Secured Party of its rights under this Subsidiary Guaranty or any
      other Loan Document to which such Subsidiary Guarantor is a party.

            (d) There is no action, suit, investigation, litigation or
      proceeding affecting such Subsidiary Guarantor, including any
      Environmental Action, pending or threatened before any court, governmental
      agency or arbitrator that (i) would be



<PAGE>

                                      7


      reasonably likely to have a Material Adverse Effect or (ii) purports to
      affect the legality, validity or enforceability of this Subsidiary
      Guaranty or any other Loan Document to which such Subsidiary Guarantor is
      a party.

            (e) This Subsidiary Guaranty and each other Loan Document to which
      it is a party has been duly executed and delivered by such Subsidiary
      Guarantor. Each of this Subsidiary Guaranty and each other Loan Document
      to which it is a party is the legal, valid and binding obligation of such
      Subsidiary Guarantor, enforceable against such Subsidiary Guarantor in
      accordance with its terms.

            (f) There are no conditions precedent to the effectiveness of this
      Subsidiary Guaranty that have not been satisfied or waived.

            (g) Such Subsidiary Guarantor has, independently and without
      reliance upon the Administrative Agent or any Lender Party and based on
      such documents and information as it has deemed appropriate, made its own
      credit analysis and decision to enter into this Subsidiary Guaranty, and
      such Subsidiary Guarantor has established adequate means of obtaining from
      any other Loan Parties on a continuing basis information pertaining to,
      and is now and on a continuing basis will be completely familiar with, the
      financial condition, operations, properties and prospects of such other
      Loan Parties.

            Section 7. Covenants. Each Subsidiary Guarantor covenants and agrees
that, so long as any part of the Guaranteed Obligations shall remain unpaid, any
Letter of Credit shall be outstanding or any Lender Party shall have any
Commitment, such Subsidiary Guarantor will at all times perform or observe, and
will cause each of its Subsidiaries to perform or observe, all of the terms,
covenants and agreements that the Loan Documents state that the Borrower is to
cause such Subsidiary Guarantor or such Subsidiaries to perform or observe.

            Section 8. Amendments, Etc. (a) No amendment or waiver of any
provision of this Subsidiary Guaranty and no consent to any departure by any
Subsidiary Guarantor therefrom shall in any event be effective unless the same
shall be in writing and signed by the Administrative Agent and the Required
Lenders, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no amendment, waiver or consent shall, unless in writing and signed by all of
the Secured Parties, (i) reduce or limit the liability of such Subsidiary
Guarantor hereunder or release any Subsidiary Guarantor hereunder, (ii) postpone
any date fixed for payment hereunder or (iii) amend this Section 8.

            (b) (i) With the consent of the Required Lenders or (ii) upon the
      merger, consolidation, sale or liquidation of any Guarantor in accordance
      with the terms of the



<PAGE>

                                      8


      Credit Agreement, the Administrative Agent will, at such Guarantor's
      expense, execute and deliver to such Guarantor such documents as such
      Guarantor shall reasonably request to evidence the release of such
      Guarantor from its obligations under this Guaranty; provided, however, as
      to clause (ii) above, that (x) at the time of such request and such
      release no Default shall have occurred and be continuing, (y) such
      Guarantor shall have delivered to the Administrative Agent, at least five
      Business Days prior to the date of the proposed release (or such shorter
      period of time as may be acceptable to the Administrative Agent), a
      written request for release identifying such Guarantor and, if the
      Subsidiary Guarantor is an Ongoing Subsidiary only, the terms of the sale,
      liquidation, merger or consolidation in reasonable detail, including, in
      the case of a sale, the price thereof and any expenses in connection
      therewith, together, in all cases, with a form of release for execution by
      the Administrative Agent and a certification by MEDIQ to the effect that
      the sale, liquidation, merger or consolidation, as the case may be, is in
      compliance with the terms of the Credit Agreement and as to such other
      matters as the Administrative Agent may reasonably request and (z) in the
      case of a sale, any proceeds of any such sale required to be applied to
      the prepayment of Advances or reduction of Commitments in accordance with
      the terms of the Credit Agreement shall be so applied; provided further as
      to any merger or consolidation in which the surviving corporation thereof
      is a Subsidiary of MEDIQ, such surviving corporation shall have assumed in
      a form satisfactory to the Administrative Agent the Guaranteed Obligations
      of such Guarantor.

            Section 9. Notices, Etc. All notices and other communications
provided for hereunder shall be in writing (including telegraphic, telecopy or
telex communication) and mailed, telegraphed, telecopied, telexed or delivered
to it, if to any Subsidiary Guarantor, to the address set forth below such
Subsidiary Guarantor's signature on the signature pages hereof, if to the
Administrative Agent, the Documentation Agent or any Lender Party, at its
address specified in the Credit Agreement, or as to any party at such other
address as shall be designated by such party in a written notice to each other
party. All such notices and other communications shall, when mailed,
telegraphed, telecopied, telexed or sent by courier, be effective when deposited
in the mails, delivered to the telegraph company, transmitted by telecopier,
confirmed by telex answerback or delivered to the overnight courier,
respectively. Delivery by telecopier of an executed counterpart of any amendment
or waiver of any provision of this Subsidiary Guaranty shall be effective as
delivery of a manually executed counterpart thereof.

            Section 10. No Waiver; Remedies. No failure on the part of the
Administrative Agent or any other Secured Party to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any



<PAGE>

                                      9


other right. The remedies herein provided are cumulative and not exclusive of
any remedies provided by law.

            Section 11. Right of Set-off. Upon (a) the occurrence and during the
continuance of any Event of Default and (b) the making of the request or the
granting of the consent specified by Section 6.01 of the Credit Agreement to
authorize the Administrative Agent to declare the Notes due and payable pursuant
to the provisions of said Section 6.01, each Lender Party and each of its
respective Affiliates is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender Party or such
Affiliate to or for the credit or the account of any Subsidiary Guarantor
against any and all of the Obligations of such Subsidiary Guarantor now or
hereafter existing under this Subsidiary Guaranty, irrespective of whether such
Lender Party shall have made any demand under this Subsidiary Guaranty and
although such Obligations may be unmatured. Each Lender Party agrees promptly to
notify such Subsidiary Guarantor after any such set-off and application;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of each Lender Party and
its respective Affiliates under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) that such
Lender Party and its respective Affiliates may have.

            Section 12. Indemnification. Without limitation on any other
Obligations of any Subsidiary Guarantor or remedies of the Secured Parties under
this Subsidiary Guaranty, each Subsidiary Guarantor shall, to the fullest extent
permitted by law, indemnify, defend and save and hold harmless each Secured
Party from and against, and shall pay on demand, any and all losses,
liabilities, damages, costs, expenses and charges (including the fees and
disbursements of such Secured Party's legal counsel) suffered or incurred by
such Secured Party as a result of any failure of any Guaranteed Obligations to
be the legal, valid and binding obligations of any Loan Party enforceable
against such Loan Party in accordance with their terms.

            Section 13. Continuing Subsidiary Guaranty; Assignments under the
Credit Agreement. This Subsidiary Guaranty is a continuing guaranty and shall
(a) remain in full force and effect until the later of the payment in full in
cash of the Guaranteed Obligations and all other amounts payable under this
Subsidiary Guaranty and the Termination Date, (b) be binding upon each
Subsidiary Guarantor, its successors and assigns and (c) inure to the benefit of
and be enforceable by the Administrative Agent and the other Secured Parties and
their successors, transferees and assigns. Without limiting the generality of
the foregoing clause (c), any Secured Party may assign or otherwise transfer all
or any portion of its rights and obligations under the Credit Agreement
(including, without limitation, all or any portion of its Commitments, the
Advances owing to it and the Note or Notes held by it) to any other Person, and
such other Person shall thereupon become vested with all the



<PAGE>

                                      10


benefits in respect thereof granted to such Secured Party herein or otherwise,
in each case as and to the extent provided in Section 9.07 of the Credit
Agreement. No Subsidiary Guarantor shall have the right to assign its rights
hereunder or any interest herein without the prior written consent of the
Secured Parties.

            Section 14. Governing Law; Jurisdiction; Waiver of Jury Trial, Etc.
(a) This Subsidiary Guaranty shall be governed by, and construed in accordance
with, the laws of the State of New York.

            (b) Each Subsidiary Guarantor hereby irrevocably and unconditionally
submits, for itself and its property, to the nonexclusive jurisdiction of any
New York State court or federal court of the United States of America sitting in
New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Subsidiary Guaranty or any of the
other Loan Documents to which it is or is to be a party, or for recognition or
enforcement of any judgment, and each Subsidiary Guarantor hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in any such New York State court or, to
the extent permitted by law, in such federal court. Each Subsidiary Guarantor
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Subsidiary Guaranty shall
affect any right that any party may otherwise have to bring any action or
proceeding relating to this Subsidiary Guaranty or any of the other Loan
Documents to which it is or is to be a party in the courts of any jurisdiction.

            (c) Each Subsidiary Guarantor irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Subsidiary Guaranty or
any of the other Loan Documents to which it is or is to be a party in any New
York State or federal court. Each Subsidiary Guarantor hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

            (d) Each Subsidiary Guarantor hereby irrevocably waives all right to
trial by jury in any action, proceeding or counterclaim (whether based on
contract, tort or otherwise) arising out of or relating to any of the Loan
Documents, the transactions contemplated thereby or the actions of the
Administrative Agent or any other Secured Party in the negotiation,
administration, performance or enforcement thereof.

            I, Jay M. Kaplan, Senior Vice President and Chief Financial Officer
of MEDIQ/PRN Life Support Services, Inc., a Delaware corporation (the
"Borrower"), hereby certify that I am the Senior Vice President and Chief
Financial Officer of the Borrower, that I am familiar with its properties,
businesses, assets, finances and operations and that I am duly authorized to
execute this Solvency Certificate on behalf of the Borrower, which is being
delivered pursuant to Section 3.01(g)(xiii) of the Credit Agreement dated as of
October 1, 1996 (as it may be hereafter amended, supplemented or otherwise
modified from time to time in accordance with its terms, the "Credit Agreement")
among the Borrower, MEDIQ Incorporated, a Delaware corporation, and PRN
Holdings, Inc., a Delaware corporation, as Parent Guarantors, the lender parties
from time to time party thereto (the "Lender Parties"), Banque Nationale de

            I further certify that I am familiar with the properties, businesses
and assets of the Borrower and have carefully reviewed the Loan Documents, the

assumptions which underlie and form the basis for the representations made in

Obligations under the Loan Documents, the Borrower has granted a security

consummation of the transactions contemplated by the Credit Agreement, the other
Loan Documents and the Related Documents, the fair value of any and all property
of the Borrower is greater than the total amount of liabilities (including

            2. On the date hereof, both before and after giving effect to the
consummation of the transactions contemplated by the Credit Agreement, the other
Loan Documents and the Related Documents, the present fair saleable value of the
assets of the Borrower exceeds the amount that will be required to pay the
probable liabilities of the Borrower on its debts as they become absolute and
matured.

            3. On the date hereof, both before and after giving effect to the
consummation of the transactions contemplated by the Credit Agreement, the other
Loan Documents and the Related Documents, the Borrower is not engaged in
business or in a transaction, and is not about to engage in business or in a
transaction, for which its capital would constitute unreasonably small capital
(after giving due consideration to the prevailing practice in the industry in
which it is engaged).

            4. The Borrower does not intend or believe that it will incur debts
and liabilities that will be beyond its ability to pay as such debts or
liabilities mature.

            5. The Borrower does not intend, in consummating the transactions
contemplated by the Credit Agreement, the other Loan Documents, or the Related
Documents, to hinder, delay or defraud either present or future creditors or any
other Person to which the Borrower is or will become, on or after the date
hereof, indebted.

            6. In reaching the conclusions set forth in this Solvency
Certificate, I have considered, on behalf of the Borrower, among other things:

            (a) the cash and other assets of the Borrower reflected in the
      Financial Statements of the Borrower;

            (b) all contingent liabilities of the Borrower including, without
      limitation, any claims arising out of pending or threatened litigation
      against the Borrower, and in so doing, the Borrower has computed the
      amount of such liabilities as the amount that, in light of all the facts
      and circumstances existing on the date hereof, represents the amount that
      can reasonably be expected to become an actual or matured liability (the
      "Contingent Liabilities");


<PAGE>

                                      3


            (c) all obligations and liabilities of the Borrower, whether matured
      or unmatured, liquidated or unliquidated, disputed or undisputed, secured
      or unsecured, subordinated, absolute, fixed or contingent (other than
      Contingent Liabilities);

            (d) historical and anticipated growth in sales volume of the
      Borrower and income stream generated by the Borrower as reflected in,
      among other things, the cash flow statements delivered as part of the
      Financial Statements;

            (e) the customary terms and trade payables of the Borrower;

            (f) the amount of the credit extended by and to customers of the
      Borrower;

            (g) the amortization requirements of the Credit Agreement and the
      Related Documents, the anticipated interest payable on the Advances and
      fees payable under the Credit Agreement;

            (h) the level of capital customarily maintained by the Borrower and
      other entities engaged in the same or similar business as the business of
      the Borrower; and

            (i) the environmental assessment reports delivered pursuant to
      Section 3.01(g)(xiv) of the Credit Agreement.

            Delivery of an executed counterpart of a signature page to this
Solvency Certificate by telecopier shall be effective as delivery of a manually
executed counterpart of this Solvency Certificate.

            I have given this Solvency Certificate (a) solely in my capacity as
an officer of the Borrower and not individually and (b) on the understanding,
and subject to the condition, that I will have no personal liability on account
of having given this Solvency Certificate.

            IN WITNESS WHEREOF, the undersigned has executed this Certificate on
behalf of the Borrower this 1st day of October, 1996.

            I, Jay M. Kaplan, Senior Vice President and Chief Financial Officer
of MEDIQ/PRN Life Support Services, Inc., a Delaware corporation (the
"Borrower"), hereby certify that I am the Senior Vice President and Chief
Financial Officer of the Borrower, that I am familiar with its properties,
businesses, assets, finances and operations and that I am duly authorized to
execute this Solvency Certificate on behalf of the Borrower, which is being
delivered pursuant to Section 3.01(g)(xiii) of the Credit Agreement dated as of
October 1, 1996 (as it may be hereafter amended, supplemented or otherwise
modified from time to time in accordance with its terms, the "Credit Agreement")
among the Borrower, MEDIQ Incorporated, a Delaware corporation, and PRN
Holdings, Inc., a Delaware corporation, as Parent Guarantors, the lender parties
from time to time party thereto (the "Lender Parties"), Banque Nationale de
Paris, as administrative agent (the "Administrative Agent") for the Lender

agent (the "Documentation Agent" and, together with the Administrative Agent,
the "Agents") for the Lender Parties. Unless otherwise defined herein,
capitalized terms defined in the Credit Agreement are used herein as therein
defined.

            I further certify that I am familiar with the properties, businesses
and assets of the Borrower and have carefully reviewed the Loan Documents, the
Related Documents and the contents of this Solvency Certificate and, in

necessary and prudent therefor. I further certify, as the Senior Vice President

consummation of the transactions contemplated by the Credit Agreement, the other

of the Borrower is greater than the total amount of liabilities (including
contingent, subordinated, absolute, fixed, matured or unmatured and liquidated
or unliquidated liabilities) of the Borrower.

            2. On the date hereof, both before and after giving effect to the
consummation of the transactions contemplated by the Credit Agreement, the other

probable liabilities of the Borrower on its debts as they become absolute and
matured.

consummation of the transactions contemplated by the Credit Agreement, the other

contemplated by the Credit Agreement, the other Loan Documents, or the Related
Documents, to hinder, delay or defraud either present or future creditors or any
other Person to which the Borrower is or will become, on or after the date
hereof, indebted.

      or unmatured, liquidated or unliquidated, disputed or undisputed, secured

            (d) historical and anticipated growth in sales volume of the
      Borrower and income stream generated by the Borrower as reflected in,
      among other things, the cash flow statements delivered as part of the
      Financial Statements;

            (f) the amount of the credit extended by and to customers of the
      Borrower;

      Related Documents, the anticipated interest payable on the Advances and
      fees payable under the Credit Agreement;

      other entities engaged in the same or similar business as the business of
      the Borrower; and

      Section 3.01(g)(xiv) of the Credit Agreement.

            Delivery of an executed counterpart of a signature page to this
Solvency Certificate by telecopier shall be effective as delivery of a manually

            I, Michael F. Sandler, Chief Financial Officer of MEDIQ
Incorporated, a Delaware corporation ("MEDIQ"), hereby certify that I am the
Chief Financial Officer of MEDIQ, that I am familiar with the properties,

            1. Attached hereto as Annex A are the projected consolidated
financial statements of the Company on a monthly basis for the first two years
following the day of the Initial Extension of Credit and on an annual basis for
each year thereafter until the Final Maturity Date (the "Projected Financial
Statements") prepared by management in good faith. The Projected Financial
Statements fairly present the best estimate of the future financial performance
of the Company and are reasonable in light of the business conditions existing
on the date hereof, although actual results during the periods covered by the
Projected Financial Statements may differ materially from the projected results
stated therein.

            7. In reaching the conclusions set forth in this Solvency

                             W I T N E S S E T H:

      WHEREAS, the Company has heretofore executed and delivered to the Trustee
the Indenture providing for the issuance of the Company's 11-1/8% Senior Secured
Notes Due 1999 (the "Senior Secured Notes"); and

      WHEREAS, Section 9.02 of the Indenture authorizes the Company and the
Trustee, with the consent of at least a majority in aggregate principal amount
of the Senior Secured Notes then Outstanding, to amend the Indenture, the
Security Documents or the Senior Secured Notes and to execute a Supplemental
Indenture in connection therewith, to make certain changes; and

      WHEREAS, all acts and proceedings required by law and by the Indenture to
constitute this Supplemental Indenture a valid and binding agreement for the
uses and purposes herein as set forth, in accordance with its terms, have been
done and taken, and the execution and delivery of this Second Supplemental
Indenture have been in all respects duly authorized by the Company.

      NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt of which is hereby acknowledged, each party
hereto covenants and agrees with the other party, for the equal and
proportionate benefit of all present and future Noteholders, as follows:

            1. The Indenture is hereby amended by deleting the following

            (g)   4.15

            (h)   4.18

            2. The definition of "Permitted Liens" is hereby amended by adding
two new clauses (xii) and (xiii) at the end of such definition as follows:

            "and (xii) Liens on any assets which are not subject to the Liens of
      the Trustee for the benefit of the Noteholders, and (xiii) Liens on assets
      subject to the Liens of the Trustee for the benefit of Noteholders, but
      which are expressly subordinate in priority to such Liens in favor of the
      Trustee created under this Indenture."

            3.    Section 2.09 of the Indenture is hereby amended by
deleting such Section in its entirety and replacing it with the
following:

      "Section 2.09.  Outstanding Senior Secured Notes.

            Senior Secured Notes outstanding at any time are all Senior Secured
      Notes that have been authenticated by the Trustee, except for those
      cancelled or deemed cancelled pursuant to Section 2.12(b) hereof by the
      Trustee, those delivered to it for cancellation and those described in
      this Section as not outstanding. A Senior Secured Note does not cease to
      be outstanding because the Company or one of its Affiliates holds the
      Senior Secured Note.

            If a Senior Secured Note is replaced pursuant to Section 2.08, it
      ceases to be outstanding unless the Trustee receives proof satisfactory to
      it that the replaced Senior Secured Note is held by a bona fide purchaser.

            If the Paying Agent (other than the Company or a Subsidiary of the
      Company) holds, on a redemption date or the Maturity Date, money
      sufficient to pay all accrued interest and principal with respect to such
      Senior Secured 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 Senior Secured Notes cease to
      be outstanding and interest on them cease to accrue."

            4.    Section 2.12 of the Indenture is hereby amended by
designating the existing text as subsection "(a)" and adding a
new subsection (b) as follows:

            "(b) In the event that the Company deposits trust monies with the
            Trustee pursuant to Section 8.01(a)(ii) hereof and the Company or an
            Affiliate of the Company


                                    -2-
<PAGE>

            holds Senior Secured Notes for which no such deposit is being made,
            all such Senior Secured Notes held by the Company or its Affiliate
            shall be deemed cancelled by the Trustee pursuant to this Section
            2.12 effective immediately prior to the Trustee's receipt of such
            deposit, regardless of whether such Senior Secured Notes have been
            delivered to the Trustee in accordance with Section 2.12(a)."

            5.    Section 4.13(b) is hereby amended by deleting such
Section and replacing it with the following:

            "(b) requires, prior to the payment in full or defeasance of the
      Senior Secured Notes, that the proceeds received from the sale of any
      Collateral be applied to repay, redeem or otherwise retire any
      Indebtedness of any Person other than the Indebtedness represented by the
      Senior Secured Notes."

            6. Section 4.17 is hereby amended by adding the following sentence
to the end of such Section:

            "Notwithstanding anything to the contrary contained herein, the
      Company and its subsidiaries and Affiliates may grant Liens on any assets
      which are not subject to the Liens of the Trustee for the benefit of the
      Noteholders."

            7. Section 5.01 of the Indenture is hereby amended by deleting
Subsection 5.01(ii) in its entirety and renumbering existing Subsection
5.01(iii) as 5.01(ii).

            8. Section 8.01 of the Indenture is hereby amended by deleting such
Section in its entirety and by replacing such Section with the following:

      "SECTION 8.01.  Termination of Obligations.

            The Company may terminate its obligations under the Senior Secured
      Notes and this Indenture, except those obligations referred to in the

                                  WITNESSETH:

            WHEREAS, MEDIQ/PRN has heretofore issued its 11-1/8% Senior Secured
Notes due 1999 (the "Senior Secured Notes"); and

            WHEREAS, the Senior Secured Notes were issued under and pursuant to
an Indenture dated as of July 6, 1992, as amended by supplemental indentures
dated as of September 30, 1994 and October 1, 1996, as amended (the

Trustee in its capacity as Collateral Agent dated as of July 6, 1992, as amended
by Amendment of even date herewith; and

            WHEREAS, MEDIQ/PRN has determined that it is desirable to defease

            WHEREAS, concurrently with the execution and delivery hereof, a
portion of the proceeds borrowed under the BNP Credit Agreement, will be used to

of the Indenture and applied for and toward the redemption on July 1, 1997, of
all Senior Secured Notes outstanding on such date at a redemption price of
103.5% of the principal amount thereof plus all outstanding interest thereon;
and

            WHEREAS, upon the deposit with the Trustee of the Defeasance Deposit

the Trustee will terminate its rights, title and interest in the Indenture; and

            WHEREAS, MEDIQ/PRN and the Trustee desire to enter into this
Agreement to set forth their respective rights and duties hereunder and to
provide for the payment of the Senior Secured Notes in accordance with the terms
hereof and the Indenture;

<PAGE>

            NOW, THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto, intending to be legally bound hereby, covenant
and agree as follows:

            SECTION 1.  Defeasance Fund.

            (a) The Trustee hereby acknowledges receipt of the securities
described on Exhibit A hereto which shall constitute the Defeasance Fund.

            (b) The Trustee shall hold the securities in the Defeasance Fund and
all money received by it from the collection of interest on the securities in
the Defeasance Fund, in special funds and separate trust accounts for the
benefit of the holders of the Senior Secured Notes, wholly segregated from all
other funds and investments deposited with the Trustee, and shall never
commingle such investments with other moneys or investments. Amounts in the
Defeasance Fund shall be applied only as hereinafter provided.

            SECTION 2. Instructions for Payment of Bonds and Notice of
Defeasance. The Trustee shall, out of the moneys available in the Defeasance
Fund after the securities in the Defeasance Fund have matured, redeem all of the
Senior Secured Notes on July 1, 1997 at a redemption price of 103.5% of the
principal amount thereof as provided in the Indenture. Notice of Redemption of
the Senior Secured Notes to be redeemed on such date, meeting the requirements
of Section 3.03 of the Indenture and substantially in the form attached hereto
as Exhibit B, shall be sent by first class mail, postage prepaid to the
registered owners of the Senior Secured Notes at their addresses set forth on
the bond registry books kept by the Trustee (in its capacity as Trustee) not
less than 30 days nor more than 60 days prior to July 1, 1997. The Trustee
shall, as soon as practicable following deposit of the securities into the
Defeasance Fund, also cause a notice of defeasance, substantially in the form
attached hereto as Exhibit C to be mailed by first class mail, postage prepaid,
to the registered owners of the Senior Secured Notes as shown on the
registration books of the Trustee. Copies of the notices described in this
Section shall also be sent by the Trustee to each other person entitled to
receive notices of redemption in accordance with the Indenture.

            SECTION 3. No Revocation or Amendment of Agreement.

      (a) Irrevocable Trust. The Trustee and MEDIQ/PRN recognize that the
holders from time to time of the outstanding Senior Secured Notes have a
beneficial and vested interest in the Defeasance Fund. It is therefore recited,
understood and agreed that this Agreement shall not be subject to revocation or
amendment if such revocation or amendment would impair the rights of such
holders.


                                    -2-
<PAGE>

      SECTION 4. Duties of Trustee: Indemnification. The Trustee agrees to
service and manage the Defeasance Fund in accordance with the terms of this
Agreement. The Trustee takes no responsibility for any acts or omissions of
MEDIQ/PRN or any other party. The Trustee shall have no obligation with respect
to this Agreement other than those duties specifically mentioned herein and
shall have the right to act upon any document or written request believed by it
to be genuine and shall have no duty to inquire into the authenticity of any
signature. The Trustee shall not be liable for the accuracy of the calculations
as to the sufficiency of the principal amount of the securities and earnings
thereon, to redeem all of the Senior Secured Notes. So long as the Trustee
applies any moneys, securities, and earnings therefrom to redeem the Senior
Secured Notes as provided herein, the Trustee shall not be liable for any
deficiencies in the amounts necessary to purchase the Senior Secured Notes
caused by such calculations. The Trustee shall also be entitled to consult and
rely upon the advice of counsel if either deems such consultations to be
necessary in the performance of its duties. Neither the Trustee nor its
officers, directors, employees or agents shall be liable to any party herein
mentioned for any action or omission taken in connection herewith unless due to
willful misconduct or gross negligence. MEDIQ/PRN hereby agrees to indemnify and
hold harmless the Trustee, its officers, directors, employees or agents from and
against any and all claims or demands, suits, liabilities, losses, court costs
and out-of-pocket expenses (including reasonable attorneys' fees) by persons or
parties, whether or not party to this Agreement, which may arise or be caused by
any act of omission of Trustee in connection with its duties hereunder, except
where due to Trustee's willful misconduct or gross negligence. The provisions of
this Section shall survive termination of this Agreement.

      SECTION 5. Termination of this Agreement. This Agreement shall be
irrevocable and shall not terminate until such time as the principal of and
interest on all Senior Secured Notes have been paid to the registered owners
thereof in accordance with the terms of the Indenture or this Agreement;
provided that moneys held by the Trustee in the Defeasance Fund shall be paid to
MEDIQ/PRN as provided in Section 8.03 of the Indenture.

      SECTION 6. Satisfaction and Discharge of the Indenture. On February 3,
1997 (the "Termination Date"), MEDIQ/PRN's obligations under the Senior Secured
Notes and the Indenture shall terminate, other than MEDIQ/PRN's obligations in
Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.13, 4.02, 7.07, 7.08, 8.03 and 8.04 of
the Indenture, which shall survive until the Senior Secured Notes are no longer
outstanding, and thereafter MEDIQ/PRN's obligations in Sections 7.07, 8.03 and
8.04 of the Indenture shall survive. Except as provided above, MEDIQ/PRN's
obligations under the Senior Secured Notes and the Indenture shall be finally
and completely discharged and released. Effective as of the Termination Date,
all liens in the Collateral and all other property of MEDIQ/PRN in


                                    -3-
<PAGE>

favor of the Trustee for the benefit of the holders of the Senior Secured Notes,
including without limitation all liens created by or arising under the
Indenture, the Security Agreement or the Collateral Account Agreement, shall be
terminated and released without need for further action by the Trustee or any
other Person. The Collateral Agent hereby agrees to execute and deliver such
instruments as MEDIQ/PRN may reasonably request to evidence the release of the
liens under the Indenture and the Security Agreement, including without
limitation (i) UCC-3 termination statements, and (ii) the return of any pledged
collateral. The Trustee hereby authorizes the filing and recording of the
release documents and termination statements.

      SECTION 7. No Rights Conferred on Others. This Agreement is made for the
sole and exclusive benefit of the parties hereto and the holders of the Senior
Secured Notes. Nothing contained in this Agreement expressed or implied is
intended or shall be construed to confer upon any person, or to give any person
other than the parties hereto and such holders of the Senior Secured Notes any
right, remedy or claim under or by reason of this Agreement.

      SECTION 8. Severability. If any provision of this Agreement shall be held
or deemed to be invalid or shall, in fact, be illegal, inoperative or
unenforceable, the same shall not affect any other provision or provisions
herein contained or render the same invalid, inoperative or unenforceable to any
extent whatsoever.

      SECTION 9. Governing Laws. This Agreement shall be governed by and
construed in accordance with the laws of the State of New Jersey.

      SECTION 10. Descriptive Headings. Section headings contained herein have
been inserted for convenience only and shall not affect the interpretation of
this Agreement.

      SECTION 11. Amendment. This Agreement may, without the consent or notice
to the holders of the Senior Secured Notes, be amended from time to time to cure
any ambiguity or formal defect or omission in this Agreement or in any
supplement hereto, and to grant to or confer upon the Trustee for the benefit of
such holders any additional rights, remedies, powers, authority or security that
may lawfully be granted to or conferred upon the Trustee.

      SECTION 12. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original as against any
party whose signature appears thereon, and all of which together shall
constitute one and the same instrument. Delivery of an executed counterpart or
signature page by telecopier shall be effective as delivery of a manually
executed counterpart.


                                    -4-
<PAGE>

      SECTION 13. Further Assurances. The Collateral Agent shall cause, at the
expense of MEDIQ/PRN, any stock certificates and other instruments which
represent collateral released hereunder to be delivered to such party as
MEDIQ/PRN may designate and shall execute such further documents as MEDIQ/PRN
may request to terminate the security interests of the Collateral Agent in such
Collateral.

     IN WITNESS WHEREOF, the parties hereto have each caused this Defeasance
Agreement to be executed by their duly authorized officers as of the date first
above written.
