                                     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 medical
equipment and, with its acquisition of the remaining 50% of SpectraCair in
September 1997, directly provides therapeutic support systems to treat, prevent
or manage pressure ulcers. The Company's customers include acute care hospitals,
alternative care facilities, nursing homes, and home health care companies.
MEDIQ/PRN constitutes the Company's principal business, accounting for 98%, 98%
and 97% of consolidated revenues from continuing operations in 1997, 1996 and
1995, respectively. The Company's other operating subsidiary, MEDIQ Management
Services, Inc., provides management and consulting services to health care
providers and management and other administrative services to diagnostic imaging
centers. The Company was incorporated in 1977. Its principal offices are located
at One MEDIQ Plaza, Pennsauken, New Jersey.

         During 1997, the Company completed its previously announced strategy of
divesting substantially all operating assets other than MEDIQ/PRN and MEDIQ
Management Services and used the proceeds thereof to reduce indebtedness. 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. In January 1997, the Company sold these shares for $88.4
million. 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, Inc. ("IHS") common stock with an initial
value of $5.2 million with the possibility of the Company receiving additional
cash consideration based upon the occurrence of certain future events. In July
1997, the Company sold the IHS shares at an amount which approximated carrying
value. In fiscal 1997, the Company received approximately $1.1 million in
additional cash consideration relating to the Mobile X-Ray transaction. In
December 1996, the Company disposed of all of its shares of NutraMax Products,
Inc. ("NutraMax") for $36.3 million, or $9.00 per share. In May 1997, the
Company sold the stock of Health Examinetics, Inc. for $1.7 million. In November
1997, the Company sold to InnoServ Technologies ("InnoServ") all of the
2,026,438 shares of InnoServ common stock owned by it, together with a warrant
to acquire additional shares of InnoServ common stock. Under the terms of the
agreement, no cash payment was made by InnoServ. However, the parties agreed to
terminate a non-compete covenant relating to maintenance and repair services. In
addition, in the event of a change of control of InnoServ before September 30,
1998, the Company will be entitled to certain payments from the acquiring party
as if it had continued to own the shares.


                                       2


<PAGE>

         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) and a portion of its subordinated debt. The 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. In
November 1997, the Company reduced the acquisition facility to $25 million.

         In February 1997, the Company entered into an agreement with Universal
Hospital Services, Inc. ("UHS") to acquire the outstanding shares of UHS for
$17.50 per share. Including the assumption of debt, the total purchase price
would have been $138 million. In April 1997, the shareholders of UHS approved
the acquisition subject to federal regulatory approval pursuant to the
Hart-Scott-Rodino Antitrust Improvements Act. In July 1997, the Company and UHS
were informed by the Federal Trade Commission ("FTC") that it had authorized its
staff to take legal action to block the proposed transaction, and subsequently
the FTC filed a motion for a preliminary injunction to block the transaction. In
September 1997, facing the likelihood of a protracted administrative proceeding
before the FTC, the uncertainty of the outcome and the costs associated with
continuing to defend against the efforts of the FTC to prevent the merger, the
Company and UHS mutually terminated the proposed acquisition.

         In September 1997, MEDIQ/PRN acquired the remaining 50% of SpectraCair
for approximately $1.9 million and the assumption of Huntleigh Healthcare's
(MEDIQ/PRN's former joint venture partner) portion of the outstanding debt of
$4.4 million.

         The Company intends to continue to expand its core business through
strategic acquisitions, which it would expect to finance, at least in part, by
drawings under its 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.

         In October 1997, the Company's Board of Directors initiated a process
to explore strategic alternatives available to the Company to maximize
shareholder value, including the possible sale of the Company, and has retained
an investment banking firm to assist in the process.


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, 1997, 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, therapeutic support
systems and other movable critical care 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 86 locations in major cities
nationwide. 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. In fiscal 1997,
the Company entered into several revenue-share arrangements with original
equipment manufacturers ("OEM") whereby the Company rents moveable medical
equipment and sells disposable products owned by the OEM to the Company's
customers. Under such 


                                       3


<PAGE>


arrangements, the Company bills the customer and pays the OEM a fee based upon a
percentage of the amount billed. Revenue-share arrangements have allowed the
Company to generate revenue without any additional capital investment. The
Company bears the risk of loss relating to the equipment and collection of
revenue. Rental revenues accounted for 80%, 84%, and 89% of consolidated
revenues in 1997, 1996 and 1995, respectively.

         MEDIQ/PRN also distributes a variety of disposable products,
accessories, and repair parts used with the types of equipment it rents.
MEDIQ/PRN provides one-stop shopping for supplies from all the leading
manufacturers, and is the exclusive distributor of accessories and supplies
manufactured by Siemens Medical Systems, Inc. for respiratory care,
catherization lab and monitoring systems. Sales of disposable products accounted
for 13%, 9% and 5% of consolidated revenues in 1997, 1996 and 1995,
respectively.

         MEDIQ/PRN offers its Comprehensive Asset Management Program (CAMP(R)),
which analyzes a customer's total critical care equipment activity from all
sources for the previous year. CAMP(R) includes a variety of logistics and
outsourcing services for movable medical equipment assets including equipment,
personnel, maintenance, documentation and tracking. MEDIQ/PRN also has programs
where it acquires all or some 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(R) 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(R) 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 optimum
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.

         Other services offered by MEDIQ/PRN include:

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

o    A medical gas administrative management service to health care providers to
     centralize the purchasing function for bulk liquid oxygen, portable and
     semi-portable oxygen containers, and high pressure gas cylinders for a
     variety of medical gas products. This program offers competitive pricing
     and price standardization for many locations, elimination of multiple local
     vendor contracts, reduction in the time it takes to process supplier
     invoices and improved purchasing efficiencies with a single-source
     contract.

o    Annual/major/electrical safety inspections, preventive maintenance and
     repairs for most brands and models of critical care equipment through a
     nationwide team of over 170 trained, experienced biomedical technicians.
     Service and repairs can be performed on-site, or pick up and delivery is
     available for servicing at any of MEDIQ/PRN's branch locations or two major
     service centers.

o    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.

o    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 1997, 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.

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 Safety and Performance Inspection
("SPI") 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 by its biomedical equipment technicians at MEDIQ/PRN's
Pennsauken, New Jersey or Santa Fe Springs, California maintenance facilities.

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 long-term agreements with three vendors to purchase
approximately $31 million of certain products over the next two fiscal years.
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 movable medical equipment rental industry is highly competitive,
and MEDIQ/PRN encounters competition in all locations in which it operates.
MEDIQ/PRN's competitors include (i) national, regional and local 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 November 1997, the Company sold to InnoServ all of the 2,026,438
shares of InnoServ common stock owned by it, together with a warrant to acquire
additional shares of InnoServ common stock. Under the terms of the agreement, no
cash payment was made by InnoServ. However, the parties agreed to terminate a
non-compete covenant relating to maintenance and repair services. In addition,
in the event of a change of control of InnoServ before September 30, 1998, the
Company will be entitled to certain payments from the acquiring party as if it
had continued to own the shares. At this time, the Company cannot determine
whether a change of control of InnoServ will occur and if a transaction would
occur, the amount of consideration it would receive. The Company had acquired
the InnoServ shares and warrant in connection with its 1994 sale of MEDIQ
Equipment and Maintenance Services, Inc.

         In May 1997, the Company sold the stock of Health Examinetics to its
management for cash and an interest bearing note aggregating $1.7 million.

                                       5


<PAGE>


         On December 31, 1996, the Company sold 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 received 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. The note does not bear a market rate of interest for
its full term. Accordingly, the Company discounted the note to $13.6 million.
The cash proceeds from this transaction were used to reduce debt.

         In November 1996, the Company sold substantially all of the assets of
Mobile X-Ray to Symphony Diagnostics, Inc., a subsidiary of IHS, for $5.3
million in cash and shares of IHS 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 July 1997,
the Company sold the IHS shares at an amount which approximated its carrying
value. Also, in fiscal 1997 the Company received approximately $1.1 million in
additional cash consideration.

         On October 11, 1996, PCI was acquired by Cardinal. In that transaction,
the Company received 1,449,000 shares (adjusted for a stock split) of Cardinal
stock in exchange for its 46% ownership interest in PCI. The Company sold its
Cardinal shares in January 1997 for $88.4 million and used the proceeds to
reduce debt.

         In September 1996, the Company sold its ownership interest in
HealthQuest 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.

Financial Information about Industry Segments

         The Company operates primarily in one business segment. The Company,
through MEDIQ/PRN, rents movable medical equipment on a short-term basis
nationwide and distributes a variety of disposable products, accessories and
repair parts used with the types of equipment it rents. In fiscal 1997, this
segment represented more than 90% of the Company's consolidated revenues,
operating profits and assets.

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 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.

         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 


                                       6

<PAGE>


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, 1997, the Company and its wholly-owned subsidiaries
had 927 employees. 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, was the subject of a 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 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 cooperated in the investigation
and denied any wrongdoing. In December 1997, desiring to avoid the delay,
expense, and uncertainty of protracted litigation, the Company reached a
settlement with the U.S. Government for $4.2 million. The settlement represents
the repayment of alleged excess Medicare reimbursements.

         In February 1997, the Company was sued in the Superior Court of New
Jersey by its former wholly-owned subsidiary, MHM Services, Inc. ("MHM";
formerly Mental Health Management, Inc.). The suit challenged the validity of a
note receivable the Company and MHM entered into upon the spin-off of MHM to
MEDIQ's shareholders in August 1993. In addition, beginning in February 1997,
MHM stopped making the required monthly installments on the note, and therefore,
the Company gave notice to MHM of its default on the note and declared all sums
outstanding under the note to be immediately due and payable. In September 1997,
as a result of continued deterioration in MHM's financial condition, the Company
recorded a reserve for the remaining balance of the note receivable, which had
been partially reserved in 1996, and accrued interest on the note receivable. In
October 1997, the Company filed a motion for summary judgment against MHM. In
November 1997, the Court granted summary judgment in favor of the Company and
against MHM on all counts. Specifically, the Court ruled that the note
receivable was valid and enforceable. The Court also rejected MHM's request for
a stay pending appeal. MHM has filed a Motion for Reconsideration which is
currently pending.

         Mobile X-Ray, the assets of which the Company sold in November 1996,
was the subject of an investigation by the Wage and Hour Division of the United
States Department of Labor (the "DOL"). The DOL had indicated that it believed
that the practice of treating technologists as exempt professionals was
incorrect. The Company maintained that the practice of treating x-ray
technologists as exempt was correct and proper. In May 1997, the Company reached
a settlement with the DOL which required the Company to pay certain Mobile X-Ray
employees back wages aggregating $213,000 including legal fees. The back wages
were paid in September 1997.

         On June 12, 1996, the Company, ATS Medical Services, Inc. ("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. Trial
has been scheduled for February 1998.

         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 J 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, 1997.

Section 16(a) Beneficial Ownership Reporting Compliance

         It has recently come to the attention of the Company that the
conversion of the Company's 7.25% Convertible Debentures Due 2006 beneficially
owned by Michael J. Rotko, Chairman of the Board of Directors, in February 1997
was not reported to the Securities and Exchange Commission in a monthly
Statement of Changes in Beneficial Ownership, as required under Section 16(a) of
the Securities Exchange Act of 1934, as amended. Mr Rotko's debentures were
automatically converted into Common Stock upon the expiration of the Company's
offer to repurchase all such debentures outstanding on February 21, 1997. This
information is currently being filed with the Securities and Exchange
Commission.

         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 1, 1997, there were approximately 1,500 holders of
record of the Company's Common Stock and approximately 300 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. On December 12, 1997, as
reported by the American Stock Exchange, the closing price per share of Common
Stock was $11.625, and the closing price per share of Series A Preferred Stock
was $11.50.

         The Company did not pay any dividends in fiscal 1997 or 1996. The
Company does not intend to pay any dividends in the foreseeable future.

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

General

         During 1997 the Company completed its previously announced strategy of
divesting substantially all operating assets other than MEDIQ/PRN and MEDIQ
Management Services and used the proceeds thereof to reduce indebtedness.

         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. In January 1997, the Company sold these shares for
$88.4 million. 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, Inc. ("IHS") common stock with an
initial value of $5.2 million with the possibility of the Company receiving
additional cash consideration based upon the occurrence of certain future
events. In July 1997, the Company sold the IHS shares at an amount which
approximated carrying value. In fiscal 1997, the Company received approximately
$1.1 million in additional cash consideration relating to the Mobile X-Ray
transaction. In December 1996, the Company sold all of its shares of NutraMax
Products, Inc. ("NutraMax") for $36.3 million, or $9.00 per share. In May 1997,
the Company sold the stock of Health Examinetics, Inc. for $1.7 million.

         In February 1997, the Company entered into an agreement with Universal
Hospital Services, Inc. ("UHS") to acquire the outstanding shares of UHS for
$17.50 per share. Including the assumption of debt, the total purchase price was
$138 million. In April 1997, the shareholders of UHS approved the acquisition
subject to approval pursuant to the Hart-Scott-Rodino Antitrust Improvements Act
("Hart-Scott-Rodino Act"). In July 1997, the Company and UHS were informed by
the Federal Trade Commission ("FTC") that it had authorized its staff to take
legal action to block the proposed transaction, and subsequently the FTC filed a
motion for a preliminary injunction to block the transaction. In September 1997,
facing the likelihood of a protracted administrative proceeding before the FTC,
the uncertainty of the outcome and the costs associated with continuing to
defend against the efforts of the FTC to prevent the merger, the Company and UHS
mutually terminated the proposed acquisition. The Company wrote-off $4 million
($2.4 million net of taxes, or $.09 per share) of deferred acquisition and
financing costs related to the proposed acquisition.

         In September 1997, MEDIQ/PRN acquired the remaining 50% of SpectraCair
for approximately $1.9 million and the assumption of Huntleigh Healthcare's
(MEDIQ/PRN's former joint venture partner) portion of the outstanding debt of
$4.4 million.

         The Company intends to continue to seek to expand its core business
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 health care industry continues to receive significant public
attention over alleged misconduct and abuses, and there have been renewed calls
for increased government regulation or oversight into various aspects of the
industry. There can be no assurance that new or more stringent government
regulations will not be adopted, or if such regulations are adopted, that they
may not adversely affect the Company.

Results of Operations

Fiscal Year 1997 Compared with Fiscal Year 1996

         Revenues from continuing operations were $156 million as compared to
$136.1 million in the prior year, an increase of $19.9 million, or 15%. The
revenue growth was attributable to a 9% increase in rental revenue, a 70%
increase in sales, and a 16% increase in other revenue. The growth in rental
revenue was primarily attributable to new revenue-share arrangements, a
sustained flu season, increased volume and the acquisition of SpectraCair. The
increase in sales was derived primarily from a significant distribution contract
which was in place during all of 1997 as compared to five months in the
comparable prior year as well as increases in sales of disposable products as a
result of additional volume attributable to an expanded customer base, a wider
variety of product offerings, a new revenue share arrangement and the expansion
of the distribution agreement to include additional product lines. The increase
in other revenue was achieved principally through outsourcing services as a
result of an expanded customer base. The Company expects to continue to
emphasize the sale of disposable products related to the types of equipment it
rents, as well as the nonrental services it has introduced, and would anticipate
that, if this strategy is successful, these activities would significantly
contribute to the Company's revenue growth.

         The Company markets its products and services to a variety of
health care and related businesses, primarily hospitals, nursing homes and home
health care companies. In recent years, these industries have undergone dramatic
consolidation and change. Although the Company is seeking to emphasize its
ability to provide services to these health care institutions in response to a
perception that such institutions are "outsourcing" increasing amounts of their
operations, there can be no assurance that this strategy will be successful.

         Operating income increased $1.9 million or 7% to $29.5 million, as
compared to $27.6 million, exclusive of a $2.2 million restructuring charge, in
the prior year. The restructuring charge was incurred in connection with the
downsizing of corporate functions and consolidation of certain activities with
the operations of MEDIQ/PRN. The improvement in operating income was
attributable to the growth in revenue-share and sales activities and reductions
in corporate overhead of $.9 million related to the downsizing of corporate
functions. This improvement was partially offset by an additional investment in
people and information systems to facilitate the accelerated growth of sales of
disposable products and revenues from outsourcing activities, higher variable
costs associated with the sustained flu season and increased volume. Operating
margins remained consistent with the prior year as a result of the Company's
growth in revenue-sharing activities and sales of disposable products which
provide a lower gross margin than the traditional rental of equipment but do not
require any capital investment.

         Interest expense decreased 30% to $19.1 million from $27.3 million in
1996 primarily as a result of substantial reductions of debt with the proceeds
from the sales of discontinued operations and lower interest rates associated
with the refinancing that occurred on October 1, 1996.

         In October 1996, the Company incurred a non-recurring charge of $11
million for the repurchase of warrants to purchase 10% of the capital stock of
MEDIQ/PRN issued in connection with financing the Kinetic Concepts, Inc.
acquisition in 1994.

         In September 1997, the Company recorded additional reserves of $5.5
million on amounts due from MHM Services, Inc. ("MHM", formerly a wholly-owned
subsidiary of the Company which was spun-off to shareholders in August 1993) as
a result of its assessment of the net realizable value of these amounts in light
of continued deterioration in MHM's financial condition. See "Item 3 - Legal
Proceedings". The Company also wrote-off $4 million of deferred acquisition and
financing costs associated with its proposed acquisition of UHS. These charges
are reflected in Other Expense-net in the Company's Consolidated Statement of
Operations.


                                       13


<PAGE>

         The Company's effective tax rate was disproportionate compared to the
statutory rate as a result of the non-deductibility of the expense associated
with the repurchase of the MEDIQ/PRN warrants, goodwill amortization and
non-recognition of certain operating losses and non-operating gains for state
income tax purposes.

         In November 1997, the Company sold to InnoServ Technologies
("InnoServ") all of the 2,026,438 shares of InnoServ common stock owned by it,
together with a warrant to acquire additional shares of InnoServ common stock.
Under the terms of the agreement, no cash payment was made by InnoServ. However,
the parties agreed to terminate a non-compete covenant relating to maintenance
and repair services. In addition, in the event of a change of control of
InnoServ before September 30, 1998, the Company will be entitled to certain
payments from the acquiring party as if it had continued to own the shares. At
this time, the Company cannot determine whether a change of control of InnoServ
will occur and if a transaction would occur, the amount of consideration it
would receive. Accordingly, the Company has recorded a reserve of $5 million
before taxes ($1.3 million after taxes) as a component of Income from
Discontinued Operations in the Company's Consolidated Statement of Operations.

         On May 7, 1997, the Company sold the stock of Health Examinetics, Inc.
to the management of Health Examinetics for approximately $1.7 million,
consisting of $.1 million in cash and an interest-bearing promissory note in the
amount of $1.6 million. The promissory note bears interest at 7% per annum and
matures in April 2003. Interest only is due on the promissory note for the first
eighteen months. Quarterly principal and interest payments commence on January
1, 1999. The sale resulted in an after-tax charge of $1 million, or $.04 per
share in addition to the estimated net loss on the disposal recorded in fiscal
1996. The charge is reflected as a component of Income from Discontinued
Operations in the Company's Consolidated Statement of Operations.

         On December 31, 1996, the Company sold 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. The Company received from NutraMax $19.9 million in cash and an
interest-bearing promissory note (the "note") in the amount of $16.4 million.
The note matures in July 2003 and bears interest at 7.5% per annum for the first
eighteen months with decreasing interest rates over the remaining term. The note
is payable when NutraMax shares owned by the Company, which are held in escrow
in support of the Company's 7.50% Exchangeable Subordinated Debentures ("7.50%
debentures") are delivered to NutraMax upon release from escrow. The NutraMax
shares are to be released from escrow upon the purchase or redemption of the
7.50% debentures. In the event the 7.50% debentures are exchanged into shares of
NutraMax, the note receivable will be reduced on a pro rata basis. The note does
not bear a market rate of interest for its full term. Accordingly, the Company
discounted the note to $13.6 million. The Company recognized an after-tax gain
of $4.8 million, or $.18 per share on the sale of the NutraMax stock which is
included in Discontinued Operations in the Company's Consolidated Statement of
Operations. From January through September 1997, the Company repurchased $17.8
million of the 7.50% debentures in the open market which resulted in the release
of 1,161,961 shares of NutraMax common stock from escrow. The shares were
delivered to NutraMax resulting in cash payments on the note of $10.5 million
and the realization of a $1.8 million pretax gain as a result of the recognition
of a portion of the discount on the note. This gain is reflected in Other
Expense-net in the Company's Consolidated Statement of Operations. At September
30, 1997, the balance of the note was $4.8 million, net of a discount of $1.1
million. The Company used the cash proceeds received from these transactions to
reduce debt.

         On November 6, 1996, the Company sold substantially all of the assets
of Mobile X-Ray to Symphony Diagnostics, Inc., a subsidiary of Integrated Health
Services, Inc. ("IHS"), for $5.3 million in cash and shares of IHS common stock
with a value of $5.2 million. In 1997, the Company received additional proceeds
of $1.1 million, with the possibility of the Company receiving additional cash
consideration based upon the occurrence of certain future events. The loss on
the disposal of these assets was recorded in fiscal 1996. In July 1997, the
Company sold the IHS shares at an amount which approximated carrying value. The
proceeds from these transactions were used to reduce debt.

         On October 11, 1996, PCI was acquired by 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 recognized
an after-tax gain of $32.6 million on this transaction as a component of Income
from Discontinued Operations in the Company's Consolidated Statement of
Operations. The Company sold its Cardinal shares in January 1997 for $88.4
million and used the proceeds to reduce debt.

         Revenues and operating income from discontinued operations (excluding
equity investees) in 1997 were $6.6 million and $.2 million, respectively, as
compared to revenues and operating income of $36.8 million and $4.3 million,
respectively, in the prior year.

         As a result of the refinancing and the repurchases of the Company's
7.25% Convertible Subordinated Debentures ("7.25% debentures") and 7.50%
debentures, the Company recognized an extraordinary charge of $13.4 million
($8.0 million, net of taxes) resulting primarily from premiums incurred related
principally to the tender offer to purchase the $100 million 11 1/8% Senior
Secured Notes due 1999 and the write-off of related deferred charges.

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%. The
revenue growth was attributable to a 66% increase in sales and a 24% increase in
other revenue, partially offset by a 2% decrease in rental revenue. The growth
in sales and other revenue 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 contracts as a result of customer purchases and
a trend in the marketplace of better utilization of equipment by customers
partially offset by an increase in the number of rental customers.

         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.

         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 in 1992. 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.


                                       15


<PAGE>


         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 investees) 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 J to the Consolidated Financial Statements.

         In September 1996, the Company sold its ownership interest in
HealthQuest 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.

         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.

Liquidity and Capital Resources

         In 1997, cash provided by operating activities was $1.2 million, as
compared to $29.1 million in the prior year. This decrease was principally
attributable to increased working capital requirements as a result of the growth
of the Company's business, particularly sales of disposable products, and
payments for income taxes.

         Net cash provided by investing activities was $101.3 million for 1997,
and consisted of cash proceeds from sales of the Company's discontinued
operations of $130.3 million partially offset by expenditures for rental medical
equipment totaling $15.5 million, the repurchase of the MEDIQ/PRN warrant for
$12.5 million and the acquisition of the remaining 50% of SpectraCair for $1.9
million. The Company presently anticipates capital expenditures of approximately
$15 million during fiscal 1998, primarily for rental medical equipment. Also,
the Company has entered into long-term agreements with three vendors to purchase
approximately $31 million of certain products over the next two fiscal years.
The Company intends to fund the disposable product purchases and rental medical
equipment expenditures with cash from operations.

        Net cash used in financing activities was $102.2 million for 1997 and
consisted primarily of debt repayments of $307.6 million related to the
refinancing, subordinated debenture repurchases and debt service and deferred
financing fees of $8.9 million associated with the refinancing, partially offset
by borrowings of $214 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 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 11 1/8%
Senior Secured Notes due 1999. Accordingly, the Company 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. In November 1997, the Company reduced the Acquisition
Revolver to $25 million.

         Borrowings under the Credit Agreement 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 (8.50% at September 30, 1997) plus .5% or Eurodollar (6.0625% at September
30, 1997) plus 2.0% and the interest rate on the Term B loan is prime plus 1.25%
or Eurodollar plus 2.75%. During fiscal 1997, the weighted average interest
rates were as follows: (i) Term A loan - 8.45%, (ii) Acquisition Revolver -
8.56%, (iii) Working Capital Revolver - 9.15%, and (iv) Term B loan 9.00%. 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
were utilized to repay outstanding advances under the Acquisition Revolver upon
receipt.

         The Term A loan is payable in quarterly installments of $1.2 million
from December 31, 1996 through September 30, 2001 and in quarterly installments
of $2.7 million from December 31, 2001 through September 30, 2002. The Term B
loan is payable in quarterly installments of $250,000 from 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, any outstanding balance
on the Acquisition Revolver will convert to a term loan which will be repaid in
quarterly installments beginning on June 30, 1998. The first two installments
will be at 5% 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 limitations. The terms of the
Company's Credit Agreement precluded the payment of dividends until October 1,
1997. The Company does not intend to pay any dividends in the foreseeable
future.

         During fiscal 1997, the Company repurchased an aggregate of $24.4
million of the 7.50% debentures at a discount in the open market with borrowings
under its credit facility. The Company may use proceeds from its Acquisition
Revolver to redeem or repurchase the remaining balance of its 7.50% exchangeable
subordinated debentures. However, except to the extent required by the terms of
the indenture pursuant to which this debenture was issued, there can be no
assurance that any additional repurchase or redemption will occur.


                                       17


<PAGE>


         During fiscal 1997, the Company repurchased or redeemed $23 million of
the 7.25% debentures. The Company funded the repurchase/redemption with
borrowings under its Credit Agreement. The remaining balance of $6.2 million of
the 7.25% debentures was converted into 833,446 shares of the Company's common
stock.

         In February 1997, the Company entered into an agreement with Universal
Hospital Services, Inc. ("UHS") to acquire the outstanding shares of UHS for
$17.50 per share. Including the assumption of debt, the total purchase price
would have been $138 million. The transaction was structured as a cash merger
and was anticipated to be funded with proceeds from the Credit Agreement. In
January 1997, the Credit Agreement was amended to increase certain components of
the facility by $50 million, subject to approval of the proposed acquisition of
UHS pursuant to the Hart-Scott-Rodino Act and by UHS' shareholders. In April
1997, the shareholders of UHS approved the acquisition subject to federal
regulatory approval pursuant to the Hart-Scott-Rodino Act. In July 1997, the
Company and UHS were informed by the Federal Trade Commission ("FTC") that it
had authorized its staff to take legal action to block the proposed transaction,
and subsequently the FTC filed a motion for a preliminary injunction to block
the transaction. In September 1997, facing the likelihood of a protracted
administrative proceeding before the FTC, the uncertainty of the outcome and the
costs associated with continuing to defend against the efforts of the FTC to
prevent the merger, the Company and UHS mutually terminated the proposed
acquisition. Consequently, the amendment to the Credit Agreement was also
terminated. The Company wrote-off $4 million ($2.4 million net of taxes, or $.09
per share) of deferred acquisition and financing costs related to the
acquisition.

         The Company expects that its primary sources of liquidity for operating
activities will be generated through cash flows from MEDIQ/PRN. The Company
believes that sufficient funds will be available from operating cash flows and
its credit facility to meet the Company's anticipated operating and capital
requirements for the foreseeable future.

Market Risk Sensitivity

         In accordance with the terms of the Credit Agreement, the Company
entered into two interest rate swap contracts ("swap contracts") on November 15,
1996. The swap contracts hedge the Company's interest rate exposure and
terminate in January 2000. The Company did not enter into the swap contracts for
trading or speculative purposes.

         The information below summarizes the Company's market risks associated
with debt obligations and swap contracts outstanding as of September 30, 1997.
Fair values of debt instruments included herein have been determined based on
quoted market prices were available. The fair values of interest rate
instruments are the estimated amounts the Company would expect to pay to
terminate the swap contracts. The information presented below should be read in
conjunction with Notes H and I to the Company's Consolidated Financial
Statements.

         For debt obligations, the table presents principal cash flows and
related interest rates by fiscal year of maturity. Fixed interest rates
disclosed represent the weighted average rates for the Company's capital leases,
except where noted. Variable interest rates disclosed represent the weighted
average rates of the portfolio at September 30, 1997. For interest rate swaps,
the table presents notional amounts and related interest rates by fiscal year of
maturity.

Recent Developments

         In October 1997, the Company's Board of Directors initiated a process
to explore strategic alternatives available to the Company to maximize
shareholder value, including the possible sale of the Company, and has retained
an investment banking firm to assist in the process.

         The Financial Accounting Standards Board has issued Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," ("SFAS 123"), which was 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. (See Note O)

         The Financial Accounting Standards Board has issued SFAS No. 128,
"Earnings Per Share," which will result in changes to the computation and
presentation of earnings per share. The Company will be required to adopt this
standard during its quarter ended December 31, 1997 with earlier adoption not
permitted. At this time, the Company does not believe the adoption of this
standard will have a material impact on the Company's earnings per share.

         The Financial Accounting Standards Board has issued SFAS No. 130,
"Reporting Comprehensive Income," which will result in disclosure of
comprehensive income and its 

                                       19

<PAGE>


components (revenues, expenses, gains and losses) in a full set of
general-purpose financial statements. The Company is not required to adopt this
standard until fiscal 1999. At this time, the Company has not determined the
impact the adoption of this standard will have on the Company's financial
statements.

         The Financial Accounting Standards Board has issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information," which
establishes standards for the way public business enterprises report information
about operating segments in annual financial statements and requires that those
enterprises report selected information about operating segments in interim
financial reports issued to shareholders. It also establishes standards for
related disclosures about products and services, geographic areas, and major
customers. The Company is not required to adopt this standard until fiscal 1999.
At this time, the Company has not determined the impact the adoption of this
standard will have on the Company's financial statements.

         The Company has and will continue to make certain investments in its
software systems and applications to ensure that the Company is year 2000
compliant. The financial impact to the Company has not been and is not
anticipated to be material to its financial position or results of operations in
any given year.

                          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, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended September 30, 1997. Our audits also
include the financial statement schedule listed in the index at Item 14(a)(2).
These financial statements and the financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and the financial statement schedule 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, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 1997 in conformity with generally accepted accounting principles.
Also, in our opinion, the financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

Note A - Summary of Significant Accounting Policies

         Description of Operations - The Company rents movable critical care and
life support medical equipment, distributes disposable products, accessories and
repair parts used with the types of equipment it rents and provides other
services to its customers in the healthcare industry.

         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. Investments in discontinued operations 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 disposable
products and repair parts for rental equipment, 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 - 2 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 $18.6 million and $15.3 million as of September 30,
1997 and 1996, 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 - The Company derives revenues from the
following sources: rental - rental of moveable medical equipment; sales - sales
of disposable products, repair parts and equipment; and other - logistical
services, maintenance and reconditioning services and management consulting
services.

         In fiscal 1997, the Company entered into several revenue-share
arrangements with original equipment manufacturers ("OEM") whereby the Company
rents moveable medical equipment and sells disposable products owned by the OEM
to the Company's customers. Under such arrangements, the Company bills the
customer and pays the OEM a fee based upon a percentage of the amount billed.
Revenue share arrangements have allowed the Company to generate revenue without
any additional capital investment. The Company bears the risk of loss relating
to the equipment and collection of revenue. The revenue related to the rental of
such OEM-owned equipment is included in rental revenue while the related fees
are reflected in operating expenses. The revenue related to the sale of the
OEM's disposable products is included in sales while the related fees are
reflected in cost of goods sold.

         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, as
income is earned or as products are shipped.

         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,
a component of Other Expense-net, in the Consolidated Statements of Operations.

<PAGE>


Note A - Summary of Significant Accounting Policies (Continued)

         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 and exercise of outstanding stock options.
Fully diluted earnings per share are not disclosed because the calculation
results in dilution of less than 3%.

         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.

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

Note B - Dispositions

         During fiscal 1997 the Company completed its previously announced
strategy of divesting substantially all operating assets other than MEDIQ/PRN
Life Support Services, Inc. ("MEDIQ/PRN") and MEDIQ Management Services, Inc.
and using the proceeds thereof  to reduce indebtedness.

         In November 1997, the Company sold to InnoServ Technologies
("InnoServ") all of the 2,026,483 shares of InnoServ common stock owned by it,
together with a warrant to acquire additional shares of InnoServ common stock.
Under the terms of the agreement, no cash payment was made by InnoServ. However,
the parties agreed to terminate a non-compete covenant relating to maintenance
and repair services. In addition, in the event of a change of control of
InnoServ before September 30, 1998, the Company will be entitled to certain
payments from the acquiring party as if it had continued to own the shares.
Accordingly, the Company has recorded a reserve of $5 million before taxes ($1.3
million after taxes) as a component of Income from Discontinued Operations in
the Company's Consolidated Statement of Operations. The Company had acquired the
InnoServ shares and warrant in connection with its 1994 sale of MEDIQ Equipment
and Maintenance Services, Inc.

         On May 7, 1997, the Company sold the stock of Health Examinetics, Inc.
to the management of Health Examinetics for approximately $1.7 million,
consisting of $.1 million in cash and an interest-bearing promissory note in the
amount of $1.6 million. The promissory note bears interest at 7% per annum and
matures in April 2003. Interest only is due on the note for the first eighteen
months. Quarterly principal and interest payments commence on January 1, 1999.
The sale resulted in an after-tax charge of $1 million, or $.04 per share in
addition to the estimated net loss on the disposal recorded in fiscal 1996. The
charge is reflected as a component of Income from Discontinued Operations in the
Company's Consolidated Statement of Operations.

         On December 31, 1996 the Company sold to NutraMax Products, Inc.
("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 received from NutraMax $19.9 million in cash and an interest-bearing
promissory note (the "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 ("7.50%
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. In
the event the 7.50% debentures are exchanged into shares of NutraMax, the note
receivable will be reduced on a pro rata basis. The note does not bear a market
rate of interest for its full term. Accordingly, the Company discounted the note
to $13.6 million and recognized an after-tax gain of $4.8 million.

                                       28

<PAGE>


Note B - Dispositions (Continued)

         From January through September 1997, the Company repurchased $17.8
million of the 7.50% debentures in the open market and a private transaction
(See Note H) which resulted in the release of 1,161,961 shares of NutraMax
common stock from escrow. The shares were delivered to NutraMax resulting in
cash payments on the Note aggregating $10.5 million and the realization of a
$1.8 million pretax gain as a result of the recognition of a portion of the
discount on the note. The gain is reflected in Other Expense-net on the
Company's Consolidated Statement of Operations. At September 30, 1997, the
balance of the note receivable was $4.8 million, net of a discount of $1.1
million. The cash proceeds from these transactions were used to reduce debt.

         In November 1996, the Company sold substantially all of the assets of
MEDIQ Mobile X-Ray Services, Inc. ("Mobile X-Ray") to Symphony Diagnostics,
Inc., a subsidiary of Integrated Health Services, Inc. ("IHS") for $5.3 million
in cash and shares of IHS 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 July 1997,
the Company sold the IHS shares at an amount which approximated its carrying
value. Also, in fiscal 1997 the Company received approximately $1.1 million in
additional cash consideration.

         On October 11, 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 recognized an after-tax gain of
$32.6 million on this transaction as a component of Income from Discontinued
Operations in the Company's Consolidated Statement of Operations. The Company
sold its Cardinal shares in January 1997 for $88.4 million and used the proceeds
to reduce debt.

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

         In August 1995, the Company sold the assets of MEDIQ Imaging Services,
Inc., 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., 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.

         Revenues from discontinued operations (excluding equity investees) were
$6.6 million, $36.8 million and $78.4 million in 1997, 1996 and 1995
respectively.

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 $1.5 million of severance benefits through September 30, 1997
with the balance of the restructuring obligation due over the next two fiscal
years.

Note D - Universal Hospital Services, Inc.

         In February 1997, the Company entered into a definitive agreement with
Universal Hospital Services, Inc. ("UHS") to acquire the outstanding shares of
UHS for $17.50 per share. Including the assumption of debt, the total purchase
price would have been $138 million. In April 1997, the shareholders of UHS
approved the acquisition subject to federal regulatory approval pursuant to the
Hart-Scott-Rodino Antitrust Improvements Act. In July 1997, the Company and UHS
were informed by the Federal Trade Commission ("FTC") that it had authorized its
staff to take legal action to block the proposed transaction, and subsequently
the FTC filed a motion for a preliminary injunction to block the


                                       29

transaction. In September 1997, facing the likelihood of a protracted
administrative proceeding before the FTC, the uncertainty of the outcome and the
costs associated with continuing to defend against the efforts of the FTC to
prevent the merger, the Company and UHS mutually terminated the proposed
acquisition. The Company wrote-off $4 million ($2.4 million net of taxes, or
$.09 per share) of deferred acquisition and financing costs related to the
proposed acquisition which is included in Other Expense-net in the Company's
Consolidated Statement of Operations.

Note E - Acquisition

         On September 18, 1997, the Company's wholly-owned subsidiary,
MEDIQ/PRN, acquired the remaining 50% interest in its SpectraCair Joint Venture
("SpectraCair") from a subsidiary of Huntleigh Healthcare ("Huntleigh") for $1.9
million in cash and the assumption of Huntleigh's portion of the outstanding
debt of SpectraCair. The acquisition was accounted for under the purchase method
of accounting and, accordingly, the purchase price was allocated to assets
acquired and liabilities assumed based on their estimated fair market values at
the date of the acquisition. The excess of the purchase price over the estimated
fair values of the net assets acquired was recorded as goodwill and is being
amortized over twenty years.

         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 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 11 1/8%
Senior Secured Notes due 1999. Accordingly, the Company 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 January 1997, the Credit Agreement was amended to increase certain
components of the facility by $50 million, subject to approval of the proposed
acquisition of UHS pursuant to the Hart-Scott-Rodino Antitrust Improvements Act
and by UHS' stockholders. This amendment was terminated in conjunction with the
termination of the proposed acquisition of UHS in September 1997. In November
1997, the Acquisition Revolver was reduced to $25 million.

         Borrowings under the Credit Agreement bear interest at either the prime
rate plus a factor or at a Eurodollar rate plus a factor. The factor may change
quarterly based upon the Company's leverage ratio, as defined in the Credit
Agreement. The Company's interest rate on the Term A loan, the Acquisition
Revolver and the Working Capital Revolver is prime (8.50% at September 30, 1997)
plus .5% or Eurodollar (6.0625% at September 30, 1997) plus 2.0% and the
interest rate on the Term B loan is prime plus 1.25% or Eurodollar plus 2.75%.
During fiscal 1997, the weighted average interest rates were as follows: (i)
Term A loan - 8.45%, Acquisition Revolver - 8.56%,


                                       31

Note H - Long Term Debt  (Continued)

(iii) Working Capital Revolver - 9.15%, and (iv) Term B loan - 9.00%. 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
were utilized to repay outstanding advances under the Acquisition Revolver upon
receipt.

         The Term A loan is payable in quarterly installments of $1.2 million
from December 31, 1996 through September 30, 2001 and in quarterly installments
of $2.7 million from December 31, 2001 through September 30, 2002. The Term B
loan is payable in quarterly installments of $250,000 from 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 limitations. The terms of the
Company's Credit Agreement precluded the payment of cash dividends until October
1, 1997. The Company does not intend to pay any dividends in the foreseeable
future.

         As a result of the refinancing, the Company recognized an extraordinary
charge of $13 million ($7.7 million net of taxes) resulting from the write-off
of deferred charges and premiums incurred related principally to the tender
offer to purchase the $100 million 11 1/8% Senior Secured Notes due 1999, and a
non-recurring charge of $11 million for the repurchase of a warrant to purchase
10% of the capital stock of MEDIQ/PRN issued in connection with financing the
Kinetic Concepts, Inc. acquisition. The non-recurring charge is reflected as
equity participation, a component of Other Expense-net, in the Company's
Consolidated Statement of Operations.

         The 7.50% debentures are exchangeable into shares of NutraMax common
stock owned by the Company, at an equivalent of $15.30 per share, and are
redeemable in whole or in part at the option of the Company. The NutraMax shares
are also held in escrow under the terms of an agreement of sale, as discussed in
Note B. Interest is payable semi-annually on January 15 and July 15. In fiscal
1997, the Company repurchased $24.4 million of the 7.50% debentures in the open
market at a discount. The Company recognized an extraordinary loss in connection
with the repurchase of the 7.50% debentures and write-offs of related deferred
charges in the aggregate amount of $26,000 net of taxes.

         During fiscal 1997, the Company repurchased or redeemed $23 million of
the 7.25% Subordinated Convertible Debentures due 2006 ("7.25% debentures"). The
Company recognized an extraordinary loss in connection with the repurchase of
the 7.25% debentures and write-offs of related deferred charges in the aggregate
amount of $.3 million. The remaining balance of $6.2 million of the 7.25%
debentures was converted into 833,446 shares of the Company's common stock.

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

Note I - Financial Instruments

         The Company utilizes interest rate swap contracts ("swap contracts") to
manage interest rate exposure. The principal objective of such contracts is to
minimize the risks and/or costs associated with financial activities. The
Company does not utilize swap contracts for trading or other speculative
purposes. The counterparties to these contractual agreements are a diverse group
of major financial institutions with which the Company also has other financial
relationships. The Company is exposed to credit loss in the event of
nonperformance by these counterparties. However, the Company does not anticipate
nonperformance by the other parties.

         Interest Rate Instruments: The Company enters into interest rate swap
and interest rate collar contracts to reduce the impact of changes in interest
rates on its floating rate debt. The swap contracts exchange floating rate for
fixed interest payments periodically over the life of the contracts without the
exchange of the underlying notional amounts. The notional amounts of swap
contracts are used to measure interest to be paid or received and do not
represent the amount of exposure to credit loss. For swap contracts that
effectively hedge interest rate exposures, the net cash amounts paid or received
on the contract are accrued and recognized as an adjustment to interest expense.

         As of September 30, 1997, the Company had the following interest rate
instruments in effect (notional amounts in thousands; the swap and collar rates
are based on 3-month LIBOR):

Note J - Commitments and Contingencies (Continued)

         Purchase Commitments - Pursuant to a Distribution Agreement and several
purchase agreements with vendors, MEDIQ/PRN has agreed to purchase approximately
$31 million of certain products in the next two fiscal years. The Company
purchased $1.2 million, $5.9 million and $2.4 million under purchase commitment
agreements in 1997, 1996 and 1995, respectively.

         Employment Agreements - The Company maintains employment agreements
with two of its Executive Officers and certain officers and employees of its
subsidiaries. Such agreements, which automatically renew each year unless
terminated as described in the agreement, provide for minimum salary levels,
adjusted annually in accordance with Company policy, as well as for incentive
bonuses that are payable if specified management goals are attained. A majority
of the employment agreements contain provisions for severance payments unless
the individual is terminated for cause or resigns. As of September 30, 1997, the
aggregate minimum commitment under these employment agreements, excluding
bonuses, was approximately $6,000,000. In addition, the agreements provide for
special bonuses to be paid to the Executive Officers, as well as the former
Chief Financial Officer, if a Sale Transaction were to occur (as defined in the
agreement). The special bonuses are based on the aggregate value of any future
transaction, and accordingly cannot be determined at this time.

Investigations and Legal Proceedings - MEDIQ Imaging, the assets of which were
sold by the Company in August 1995, was the subject of a 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 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
cooperated in the investigation and denied any wrongdoing. In December 1997,
desiring to avoid the delay, expense, and uncertainty of protracted litigation,
the Company reached a settlement with the U.S. Government for $4.2 million,
which was fully reserved as of September 30, 1997. The settlement represents the
repayment of alleged excess Medicare reimbursements.

         In February 1997, the Company was sued in the Superior Court of New
Jersey by its former wholly-owned subsidiary, MHM Services, Inc. ("MHM";
formerly Mental Health Management, Inc.). The suit challenged the validity of a
note receivable the Company and MHM entered into upon the spin-off of MHM to
MEDIQ's shareholders in August 1993. In addition, beginning in February 1997,
MHM stopped making the required monthly installments on the note, and therefore,
the Company gave notice to MHM of its default on the note and declared all sums
outstanding under the note to be immediately due and payable. In September 1997,
as a result of continued deterioration in MHM's financial condition, the Company
recorded a reserve for the remaining balance of the note receivable, which had
been partially reserved in 1996, and accrued interest on the note receivable. In
October 1997, the Company filed a motion for summary judgment against MHM. In
November 1997, the Court granted summary judgment in favor of the Company and
against MHM on all counts. Specifically, the Court ruled that the note
receivable was valid and enforceable. The Court also rejected MHM's request for
a stay pending appeal. MHM has filed a Motion for Reconsideration which is
currently pending.

         Mobile X-Ray, the assets of which the Company sold in November 1996,
was the subject of an investigation by the Wage and Hour Division of the United
States Department of Labor (the "DOL"). The DOL had indicated that it believed
that the practice of treating technologists as exempt professionals was
incorrect. The Company maintained that the practice of treating x-ray
technologists as exempt was correct and proper. In May 1997, the Company reached
a settlement with the DOL which required the Company to pay certain Mobile X-Ray
employees back wages aggregating $213,000 including legal fees. The back wages
were paid in September 1997.

         On June 12, 1996, the Company, ATS Medical Services, Inc. ("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. Trial has been scheduled for February
1998.

         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.

Note K - 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, 1997.

         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 $145.8 million and $146.2 million, respectively.

         Interest Rate Instruments - The fair values are the estimated amounts
         that the Company would receive or pay to terminate the agreements at
         September 30, 1997, taking into account current interest rates and the
         current creditworthiness of the counterparties. At September 30, 1997,
         the notional amounts were $100 million, the carrying value was $61,000
         and the fair value was $304,000, which represents the cost to settle
         these instruments.

The fair value estimates presented herein are based on information available to
management as of September 30, 1997, 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 L  - 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 M - Income Taxes (Continued)

During fiscal 1997, the Company utilized $49.7 million of net operating loss
carry forwards and $25.5 million of capital loss carry forwards. At September
30, 1997, for income tax purposes, the Company had alternative minimum tax
credit carry forwards of approximately $1.6 million. State net operating loss
carry forwards were $81.6 million, expire through 2010, and are fully reserved
in the valuation allowance. The Company also had a carry forward of Investment
Tax Credit and Rehabilitation Tax Credit of $219,000 expiring through 2003.

Note N - Related Party Transactions

In connection with the spin-off of MHM in fiscal 1993, MHM was obligated to the
Company pursuant to a promissory note with MHM in the original amount of $11.5
million due in August 1998. The note bears interest at the prime rate plus 1.5%
with interest payments only through fiscal 1995. Principal and interest payments
commenced October 1, 1996. The Company recorded interest income related to the
MHM note of $1 million, $1.1 million and $1.2 million in 1997, 1996 and 1995,
respectively. As a result of the continued deterioration in MHM's financial
condition, the Company established reserves of $5.5 million and $6 million on
amounts due from MHM, including accrued interest, in fiscal 1997 and 1996
respectively.

In 1997, 1996 and 1995, the Company incurred legal fees of approximately $2.2
million, $657,000, and $700,000 respectively, to a law firm in which the
Company's Chairman of the Board of Directors was a partner.

In 1997 and 1996, the Company incurred consulting fees of approximately $85,000
and $126,000 respectively to a law firm of which another member of the Board of
Directors is a partner.

The Company derived revenues of $33,000, $175,000 and $340,000 in 1997, 1996 and
1995, respectively, pursuant to agreements to provide financial management,
legal and risk management services to PCI, NutraMax, MHM and InnoServ.

Note O - Stock Option Plans

The Company maintains stock option plans (the "Plans") for the benefit of
officers and key employees of the Company and its subsidiaries. Options granted
vest over periods up to five years and are exercisable for periods up to ten
years from the date of grant at a price which equals fair market value at the
date of grant.

The Company accounts for the Plans in accordance with APB Opinion No. 25, under
which no compensation cost has been recognized. Had compensation cost for the
Plans been determined consistent with SFAS No. 123, "Accounting for Stock-Based
Compensation," the Company's net income and earnings per share would have been
reduced by $556,000 and $.02 per share, respectively, for fiscal 1997 and
$129,000 and $.01 per share respectively, for fiscal 1996.

Because the SFAS 123 method of accounting has not been applied to options
granted prior to October 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

The following summarizes all stock option transactions for the Company under the
Plans from October 1, 1994 through September 30, 1997:

         The weighted average fair value of options granted during fiscal 1997
and 1996 was $2.1 million and $2.3 million respectively. The fair value of the
options granted were estimated on the date of grant using the Black-Scholes
option-pricing model with the following assumptions for grants in both fiscal
1997 and 1996: risk-free interest rates ranging from 5.48% to 6.43%, expected
life of 7 years, expected volatility of 36% and dividend yield of 0%.

Note P - 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.

                            STOCK PURCHASE AGREEMENT

         This STOCK PURCHASE AGREEMENT, dated as of November 13, 1997 (the
"Agreement"), among MEDIQ Incorporated, a Delaware corporation ("MEDIQ"), MEDIQ
Investment Services, Inc., a Delaware corporation ("MIS" and together with
MEDIQ, collectively the "Seller"), and InnoServ Technologies, Inc., a California
corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, Seller owns 2,026,438 shares (the "Issuer Shares") of the
common stock of the Company (the "Common Stock") and warrants to purchase
325,000 shares of Common Stock (the "Warrants"); and

         WHEREAS, the Seller and the Company had previously entered into an
agreement pursuant to which Seller would be required to distribute the Issuer
Shares to its stockholders upon demand by the Company; and

         WHEREAS, by letter dated September 26, 1997 (the "Distribution
Request"), the Company has requested that Seller distribute the Issuer Shares to
its stockholders, such distribution to be completed no later than 60 days from
the date of such letter; and

         WHEREAS, the Seller requested that the Company consider alternative
arrangements with respect to the Issuer Shares, and the respective Boards of
Directors of the Company and the Seller have considered such alternative
arrangements; and

         WHEREAS the Seller and the Company desire that in lieu of distribution
that Seller will sell and transfer such shares to Company in accordance with the
terms and conditions hereof; and

         NOW, THEREFORE, in consideration of the mutual premises and agreements
set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by the parties, the parties hereto
agree as follows:



<PAGE>



1.       SALE OF THE SHARES


         1.1 Sale. Simultaneously with the execution and delivery hereof, the
Seller shall transfer, assign, sell and deliver to the Company, and the Company
shall purchase from the Seller all of the Issuer Shares and Warrants in
consideration of the agreements and waivers of the parties contained herein (the
"Purchase Price"). The closing (the "Closing") of the sale and purchase and
delivery of all of the Issuer Shares and Warrants shall be held on the date
hereof. At the Closing Seller shall deliver the certificates for the Issuer
Shares and the Warrants duly endorsed or accompanied by stock powers or other
appropriate instruments of transfer duly executed in blank.

         1.2 Change in Control.

            (a) Before April 1, 1998, the Company shall not enter into or
consummate a change in control (as defined below) unless the other party or
parties thereto agree, as a condition precedent to such transaction, to pay
Seller the amount (subject to the last sentence of this paragraph) that would
have been received by the Seller in connection with the change of control
transaction if all of the Issuer Shares were outstanding and held by the Seller
at the effective time of such change in control transaction. From and after
April 1, 1998 and through September 30, 1998, the Company shall not enter into
or consummate a change of control unless the other party or parties thereto
agree, as a condition precedent to such transaction, to pay Seller 50% of the
amount (subject to the last sentence of this paragraph) that would have been
received by the Seller in connection with the change of control transaction if
all of the Issuer Shares were outstanding and held by the Seller at the
effective time of such change in control transaction. Any amounts owed to Seller
pursuant to this Section 1.3 shall be paid simultaneously with the payment to
the Company's shareholders in connection with the consummation of any
transaction that constitutes a change in control of the Company. The Company
shall not enter into any change in control transaction or cooperate with any
third party with respect to a possible change in control transaction unless the
other party (or parties) thereto agree to make adequate provision for the
payment to Seller of all amounts provided herein. If the Company's shareholders
are entitled to receive Marketable Consideration (as defined below) and other
consideration in respect of a share of Common Stock, the amount that is due to
Seller shall be determined only with respect to the portion that is Marketable
Consideration.

            (b) For purposes of this Agreement, the parties intend that a
"change in control" means a transaction or series of transactions in which the
holders of a majority of the outstanding Common Stock receive (or have the right
to receive) Marketable Consideration, in respect of their shares of Common Stock
(whether by merger, sale, tender, dissolution or otherwise). For the purposes of
this Agreement, Marketable Consideration means cash, debt or publicly traded
equity securities of a company that had been a public company before such
transaction (including preferred stock or any right to acquire such publicly
traded equity security) ("Marketable Consideration"). By way of illustration, a
change in control shall include: (i) the consolidation or merger of the Company
pursuant to which the outstanding shares of Common Stock are converted into the
right to receive Marketable Consideration or (ii) the sale of all or


<PAGE>

substantially all of the assets of the Company for Marketable Consideration or
(iii) any other transaction involving an exchange or sale of 50% or more of the
outstanding Common Stock, including a tender offer, for Marketable
Consideration, but excluding all other transactions, including where the holders
of the outstanding Common Stock receive only securities of the Company or of
another entity of which the Company's assets or business constitute a
substantial portion, or reincorporation of the Company in a jurisdiction other
than California.

            (c) For purposes of determining the amount which Seller would have
received with respect to the Issuer Shares following a change in control, (1) in
any transaction involving a sale or exchange of any shares of Common Stock, it
shall be presumed that all of the Issuer Shares were sold at the highest average
price paid to any affiliate of the Issuer for any shares in such transaction,
(2) in any transaction involving a merger or consolidation of the Company, it
shall be presumed that the Seller (as a shareholder) voted in favor of such
transaction, (3) in any transaction involving the sale of all or substantially
all of the assets of the Company, it shall be presumed that the Company was
dissolved and its net assets distributed to its shareholders immediately after
such transaction and (4) in any other change in control transaction in which a
majority of the Company's shareholders which are not affiliates of the Company
receive any consideration in respect of their shares of Common Stock, the Seller
shall be presumed to have the right to receive an equivalent amount.
Furthermore, in the event of a tender or exchange offer for less than all of the
outstanding Common Stock, the Seller shall be treated as if it had tendered
(which tender had been accepted) a percentage of the Issuer Shares equal to the
highest percentage of shares of Common Stock owned by any shareholder of the
Company which are accepted by the party making such offer; and in addition the
Seller shall be entitled to receive an equivalent amount of any securities of
the Company retained by such shareholder.

            (d) The Seller acknowledges that neither the Company nor any of its
affiliates (i) has any fiduciary duty to Seller, any of Seller's affiliates or
any of Seller's stockholders (the "Seller Group") by reason of this Agreement,
(ii) is under any duty or obligation to the Seller Group to initiate,
investigate, consider, respond or otherwise take any action with respect to a
proposal that may result in a change of control by reason of this Agreement, any
such potential transaction as with respect to the Seller Group being within the
sole discretion of the Company, and (iii) any such potential transaction will be
considered by the Company in light of the duties owed to the holders of the
Common Stock outstanding at such time. Notwithstanding the above, if any third
party approaches the Company or any of its affiliates or representatives
regarding a possible change in control, the Company shall in good faith not
delay or defer such consideration, evaluation or negotiation with the intent to
reduce any amounts payable to Seller hereunder.

            (e) Subject to the last sentence of Section 1.2(a), any payment due
to Seller under this Section 1.2 shall, unless Seller otherwise agrees, be paid
in cash or in property of the kind and in the same proportion received by the

         (2) The Borrower seeks to acquire (the "UHS Acquisition") Universal

         (3) The Required Lenders are, on the terms and conditions stated below,

incurred in connection with the UHS Acquisition for (i) acquisition expenses,
lease related expenses, facility closure expenses and professional and other
fees, and (ii) the write-down of UHS's Demand Positive Airway Pressure Devices

         SECTION 2. Waiver. The provisions of Section 5.02(f)(i)(4) are hereby

Investments outstanding after giving effect to the UHS Acquisition to
$140,000,000.

         SECTION 3. Conditions of Effectiveness. This Amendment and Waiver shall
become effective as of the date first above written when, and only when, the
Administrative Agent shall have received counterparts of this Amendment and
Waiver executed by the Borrower and the Required Lenders, or, as to any of the
Lenders, advice satisfactory to the Administrative Agent that such Lender has
executed this Amendment and Waiver. The effectiveness of this Amendment and
Waiver is conditioned upon the accuracy of the factual matters described herein.

valid and binding obligations of each such Loan Party, enforceable against each
such Loan Party in accordance with their respective terms.

         (e) There is no action, suit, investigation, litigation or proceeding
affecting any Loan Party or any of their Subsidiaries (including, without
limitation, any Environmental Action) pending or threatened before any court,
governmental agency or arbitrator that (i) would be reasonably likely to have a
Material Adverse Effect or (ii) purports to affect the legality, validity or
enforceability of this Amendment and Waiver, the Collateral Documents, any
amendments or supplements thereto contemplated hereby or any of the other Loan
Documents, as amended hereby, or the consummation of any of the transactions
contemplated hereby.

secure the payment of all Obligations of the Loan Parties under the Loan
Documents, in each case as amended by this Amendment and Waiver.

         (c) The execution, delivery and effectiveness of this Amendment and
Waiver shall not, except as expressly provided herein, operate as a waiver of
any right, power or remedy of any Lender or the Agent under any of the Loan
Documents, nor constitute a waiver of any provision of any of the Loan
Documents.

         SECTION 6. Costs, Expenses. The Borrower agrees to pay on demand all
costs and expenses of the Agent in connection with the preparation, execution,
delivery and administration, modification and amendment of this Amendment and
Waiver, and the other instruments and documents to be delivered hereunder

         SECTION 1. Amendments to the Credit Agreement. Section 5.04(f) of the
Credit Agreement is, effective as of the date hereof and subject to the
satisfaction of the conditions precedent set forth in Section 2 hereof, hereby
amended by deleting the phrase "in any Fiscal Year to exceed $14,000,000"
contained therein and substituting for such phrase the phrase "in Fiscal Year
1997 to exceed $17,000,000 and in any Fiscal Year thereafter to exceed
$14,000,000".

         SECTION 2. Conditions of Effectiveness. This Amendment shall become
effective as of the date first above written when, and only when, the
Administrative Agent shall have received counterparts of this Amendment executed
by the Borrower and the Required Lenders, or, as to any of the Lenders, advice
satisfactory to the Administrative Agent that such Lender has executed this
Amendment. The effectiveness of this Amendment is conditioned upon the accuracy
of the factual matters described herein. This Amendment is subject to the
provisions of Section 9.01 of the Credit Agreement.

         SECTION 3. Representations and Warranties of the Borrower. The Borrower
represents and warrants as follows:

         (b) The execution, delivery and performance by each Loan Party of this
Amendment and the Loan Documents, as amended hereby, to which it is or is to be
a party, and the consummation of the transactions contemplated hereby, are
within such Loan Party's corporate powers, have been duly authorized by all
necessary corporate action and do not (i) contravene each such Loan Party's
charter or by-laws, (ii) violate any law (including, without limitation, the
Securities Exchange Act of 1934, as amended, and the Racketeer Influenced and
Corrupt Organizations Chapter of the Organized Crime Control Act of 1970), rule
or regulation (including, without limitation, Regulation X of the Board of
Governors of the Federal Reserve System), or any order, writ, judgment,
injunction, decree, determination or award, binding on or affecting any Loan
Party or any of its Subsidiaries or any of their properties, (iii) conflict with
or result in the breach of, or constitute a default under, any contract, loan
agreement, indenture, mortgage, deed of trust, lease or other instrument binding
on or affecting any Loan Party, any of their Subsidiaries or any of their
properties or (iv) except for the Liens created under the Collateral Documents,

         (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 the due execution, delivery, recordation, filing or
performance by any Loan Party of this Amendment, any of the Collateral Documents
or any amendments or supplements thereto contemplated hereby to which each such
Loan Party is or is to be a party, or any of the Loan Documents, as amended
hereby, to which it is or is to be a party.

         (d) This Amendment and each of the Collateral Documents and amendments
and supplements thereto contemplated hereby to which each Loan Party is a party
have been duly executed and delivered by each such Loan Party. This Amendment
and each of the other Loan Documents, as amended hereby, to which each Loan
Party is a party are, and each of the other Collateral Documents and amendments
and supplements thereto contemplated hereby to which each such Loan Party is or
is to be a party, when delivered hereunder, will be, legal, valid and binding
obligations of each such Loan Party, enforceable against each such Loan Party in
accordance with their respective terms.

         (e) There is no action, suit, investigation, litigation or proceeding
affecting any Loan Party or any of their Subsidiaries (including, without
limitation, any Environmental Action) pending or threatened before any court,
governmental agency or arbitrator that (i) would be reasonably likely to have a
Material Adverse Effect or (ii) purports to affect the legality, validity or
enforceability of this Amendment, the Collateral Documents, any amendments or
supplements thereto contemplated hereby or any of the other Loan Documents, as
amended hereby, or the consummation of any of the transactions contemplated
hereby.

         SECTION 4. Reference to and Effect on the Loan Documents. (a) On and
after the effectiveness of this Amendment, each reference in the Credit
Agreement to "this Agreement", "hereunder", "hereof" or words of like import
referring to the Credit Agreement, and each reference in the Notes and each of
the other Loan Documents to "the Credit Agreement", "thereunder", "thereof" or
words of like import referring to the Credit Agreement, shall mean and be a
reference to the Credit Agreement, as amended by this Amendment.

         (b) The Credit Agreement, the Notes and each of the other Loan
Documents, as specifically amended by this Amendment, are and shall continue to
be in full force and effect and are hereby in all respects ratified and
confirmed. Without limiting the generality of the foregoing, the Collateral
Documents and all of the Collateral described therein do and shall continue to
secure the payment of all Obligations of the Loan Parties under the Loan
Documents, in each case as amended by this Amendment.

         (c) The execution, delivery and effectiveness of this Amendment shall
not, except as expressly provided herein, operate as a waiver of any right,
power or remedy of any Lender or the Agent under any of the Loan Documents, nor
constitute a waiver of any provision of any of the Loan Documents.

in accordance with the terms of Section 9.04 of the Credit Agreement.

         SECTION 6. Execution in Counterparts. This Amendment 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 but one and the same agreement.

                       Amendment No. 4 to Credit Agreement


<PAGE>


                        AMENDMENT NO. 4 AND WAIVER TO THE
                                CREDIT AGREEMENT


                                                  Dated as of September 17, 1997

         AMENDMENT NO. 4 AND WAIVER TO THE CREDIT AGREEMENT, among MEDIQ/PRN
LIFE SUPPORT SERVICES, INC., a Delaware corporation (the "Borrower"), MEDIQ
INCORPORATED, a Delaware corporation ("MEDIQ"), PRN HOLDINGS, INC., a Delaware
corporation (together with MEDIQ, the "Parent Guarantors"), the banks, financial
institutions and other institutional lenders parties to the Credit Agreement
referred to below (collectively, the "Lenders") and Banque Nationale de Paris as
administrative agent (the "Administrative Agent") for the Lenders and
NationsBank N.A., as documentation agent (the "Documentation Agent").

         PRELIMINARY STATEMENTS:

         (1) The Borrower, the Parent Guarantors, the Lenders, the
Administrative Agent and the Documentation Agent have entered into a Credit
Agreement dated as of October 1, 1996, as amended by Amendment No. 1 dated as of
January 24, 1997, as further amended by Amendment No. 2 and Waiver dated as of
April 1, 1997 and Amendment No. 3 dated as August 8, 1997 (as so amended, the
"Credit Agreement"). Capitalized terms not otherwise defined in this Amendment
and Waiver have the same meanings as specified in the Credit Agreement.

         (2) The Borrower currently owns a 50% interest in Mediq PRN/HNE, LLC
("SpectraCair"), and its joint venture partner HNE Rentals, Inc. ("HNE") owns
the remaining 50% interest. The Borrower and MEDIQ desire to purchase HNE's
interest in SpectraCair for aggregate consideration (including the assumption of
approximately $4.25 million in Debt) of approximately $6.25 million (the
"Transaction"), as a result of which the Borrower and MEDIQ would collectively
own 100% of SpectraCair. Within seven Business Days following the consummation
of the Transaction, MEDIQ would transfer all of its interest in SpectraCair to
the Borrower, and SpectraCair would become a division of the Borrower.

         (3) The Borrower has requested that the Required Lenders amend and
waive certain provisions of the Credit Agreement to enable it to consummate the
Transaction, and, following the Transaction, to allow SpectraCair to continue to
honor certain pre-existing agreements.

         (4) The Required Lenders are, on the terms and conditions stated below,
willing to grant the request of the Borrower and the Borrower, the Parent
Guarantors and such Lenders have agreed to amend and waive the Credit Agreement
as hereinafter set forth.

         SECTION 1. Waiver to the Credit Agreement. (a) The Required Lenders
hereby waive the provisions of Section 5.02(f) of the Credit Agreement through
and including September 25, 1997 only, solely to the extent necessary to permit
the Borrower and MEDIQ to jointly invest in SpectraCair.

         (b) The Required Lenders hereby waive the provisions of Section 5.02(d)
of the Credit Agreement solely in order to permit the merger and consolidation
of SpectraCair with and into the Borrower, with the Borrower as the surviving
corporation (the "Merger").

         SECTION 2. Amendments to the Credit Agreement. The Credit Agreement is,
effective as of the date hereof and subject to the satisfaction of the
conditions precedent set forth in Section 3 hereof, hereby amended as follows:

            (1) Section 1.01 is amended by inserting the following definition in
its proper alphabetical order:

               "'SpectraCair' means Mediq PRN/HNE, LLC, a New Jersey limited
liability company."

            (2) Section 5.02(b)(ii) is amended by deleting the word "and" at the
end of paragraph (H) thereof and inserting the following:

               "(I) Debt consisting of take-or-pay contracts assumed by the
Borrower in connection with the acquisition of SpectraCair in an aggregate
amount not to exceed $3,000,000, and".

            (3) Section 5.02(f) is amended by deleting the word "and" at the end
of clause (viii) thereof and inserting the following immediately before the
period at the end of clause (ix) thereof:

               "(x) Investments in the common stock of MEDIQ made prior to
September 17, 1997, to the extent that such common stock is held in reserve for
the exercise of management stock options by executives of SpectraCair".

            (4) Section 5.02(o) is amended by inserting immediately prior to the
period at the end thereof the phrase "and take-or-pay contracts otherwise
permitted under Section 5.02(b)(ii)(I)".

         SECTION 3. Conditions of Effectiveness. (a) This Amendment and Waiver
shall become effective as of the date first above written when, and only when,
the Administrative Agent shall have received counterparts of this Amendment and
Waiver executed by the Borrower and the Required Lenders, or, as to any of the
Lenders, advice satisfactory to the Administrative Agent that such Lender has
executed this Amendment and Waiver, and counterparts of the Consent attached

consummated in compliance with all applicable laws, together with a certified
copy of a certificate of merger or other confirmation from the Secretary of

and substance satisfactory to the Administrative Agent, together with executed
copies of any uniform commercial code financing statements, Mortgages, fixture
filings or any other instruments, documents or opinions that the Administrative
Agent may deem necessary or desirable in order to perfect and protect the liens
and security interests created under the Security Agreement, the other
Collateral Documents and such supplement.

         SECTION 4. Representations and Warranties of the Borrower. The Borrower
and the Parent Guarantors each represent and warrant as follows:

such Loan Party's charter or by-laws, (ii) violate any law (including, without
limitation, the Securities Exchange Act of 1934, as amended, and the Racketeer

on or affecting any Loan Party, any of their Subsidiaries or any of their
properties or (iv) except for the Liens created under the Collateral Documents,
as amended and waived hereby, or any amendments or supplements thereto
contemplated hereby, result in or require the creation or imposition of any Lien
upon or with respect to any of the properties of any Loan Party or any of its
Subsidiaries.

         (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 the due execution, delivery, recordation, filing or
performance by any Loan Party of this Amendment and Waiver, any of the
Collateral Documents or any amendments or supplements thereto contemplated
hereby to which each such Loan Party is or is to be a party, or any of the Loan
Documents, as amended and waived hereby, to which it is or is to be a party.

         (d) This Amendment and Waiver and each of the Collateral Documents and
amendments and supplements thereto contemplated hereby to which each Loan Party
is a party have been duly executed and delivered by each such Loan Party. This
Amendment and Waiver and each of the other Loan Documents, as amended and waived
hereby, to which each Loan Party is a party are, and each of the other
Collateral Documents and amendments and supplements thereto contemplated hereby
to which each such Loan Party is or is to be a party, when delivered hereunder,
will be, legal, valid and binding obligations of each such Loan Party,
enforceable against each such Loan Party in accordance with their respective
terms.

         (e) There is no action, suit, investigation, litigation or proceeding
affecting any Loan Party or any of their Subsidiaries (including, without
limitation, any Environmental Action) pending or threatened before any court,
governmental agency or arbitrator that (i) would be reasonably likely to have a
Material Adverse Effect or (ii) purports to affect the legality, validity or
enforceability of this Amendment and Waiver, the Collateral Documents, any
amendments or supplements thereto contemplated hereby or any of the other Loan
Documents, as amended and waived hereby, or the consummation of any of the
transactions contemplated hereby.

ratified and confirmed. Without limiting the generality of the foregoing, the
Collateral Documents and all of the Collateral described therein do and shall
continue to secure the payment of all Obligations of the Loan Parties under the
Loan Documents, in each case as amended and waived by this Amendment and Waiver.

         (c) The execution, delivery and effectiveness of this Amendment and
Waiver shall not, except as expressly provided herein, operate as a waiver of
any right, power or remedy of any Lender or the Agent under any of the Loan
Documents, nor constitute a waiver of any provision of any of the Loan
Documents.

costs and expenses of the Agent in connection with the preparation, execution,
delivery and administration, modification and amendment of this Amendment and

                      (6) Fair Market Value. The term "Fair Market Value" shall
           mean the fair market value of the optioned shares of Common Stock,
           which shall be arrived at by a good faith determination of the
           Committee and shall be:

                                 (A) The mean between the highest and lowest
                      quoted selling price, if there is a market for the Common
                      Stock on a registered securities exchange or in an over
                      the counter market, on the date of grant;

                                 (B) The weighted average of the means between
                      the highest and lowest sales on the nearest date before
                      and the nearest date after the date of grant, if there are
                      no sales on the date of grant but there are sales on dates
                      within a reasonable period both before and after the date
                      of grant;

                                 (C) The mean between the bid and asked prices,
                      as reported by the National Quotation Bureau on the date
                      of grant, if actual sales are not available during a
                      reasonable period beginning before and ending after the
                      date of grant; or

                                 (D) Such other method of determining fair
                      market value as shall be authorized by the Code, or the
                      rules or regulations thereunder, and adopted by the
                      Committee. Where the fair market value of the optioned
                      shares of Common Stock is determined under (B) above, the
                      average of the means between the highest and lowest sales
                      on the nearest date before and the nearest date after the
                      date of grant is to be weighted inversely by the
                      respective numbers of trading days between the selling
                      dates and the date of grant (i.e., the valuation date), in
                      accordance with Treas. Reg. ss. 20.2031-2(b)(1).

           Option" ("ISO") shall mean an option which, at the time such option
           is granted under the Plan, qualifies as an ISO within the meaning of
           section 422 of the Code and is designated as an ISO in the Option
           Agreement.

                      (8) Key Employees. The term "Key Employees" shall mean
           officers and other key employees of the Company or a Related
           Corporation.

           Directors" shall mean directors of the Company who:


                                 (A) Are not employees of the Company or any

<PAGE>


                                 (B) Have not been employees of the Company or
                      any Related Corporation during the immediately preceding
                      12-month period.

                      (10) Non-Qualified Stock Option. The term "Non-Qualified
           Stock Option" ("NQSO") shall mean an option which, at the time such
           option is granted, does not qualify as an ISO, and/or is designated
           as an NQSO in the Option Agreement.

                      (11) Option Agreement. The term "Option Agreement" shall
           mean a written document evidencing the grant of an Option, as
           described in Section 8.

                      (12) Optionee. The term "Optionee" shall mean a Key
           Employee or Non-Employee Director to whom an Option has been granted.

                      (13) Options. The term "Options" shall mean Incentive
           Stock Options and Non-Qualified Stock Options.

                      (14) Plan. The term "Plan" shall mean the MEDIQ
           Incorporated 1997 Stock Option Plan, as set forth herein and as
           amended from time to time.

                      (15) Related Corporation. The term "Related Corporation"

           in section 424(f) of the Code or the corporate parent of the Company,

           Notwithstanding Sections 1(b)(7) and (10), if an Option granted to a
     Key Employee is not designated in the Option Agreement as an ISO or NQSO,
     the option shall constitute an ISO if it complies with the terms of section
     422 of the Code, and otherwise, it shall constitute an NQSO.

                           SECTION 2 - Administration

           The Plan shall be administered by the Committee. Each member of such
Committee, while serving as such, shall be deemed to be acting in his or her
capacity as a director of the Company.

           The Committee shall have full authority, subject to the terms of the
Plan, to select the Key Employees to be granted ISOs and/or NQSOs under the
Plan, to select the Non-Employee Directors to be granted NQSOs under the Plan,
to grant Options on behalf of the Company and to set the date of grant and the
other terms of such Options. The Committee may correct any defect, supply any
omission and reconcile any inconsistency in this Plan and in any Option granted

                                       -3-


<PAGE>


hereunder in the manner and to the extent it shall deem desirable. The Committee
also shall have the authority to establish such rules and regulations, not
inconsistent with the provisions of the Plan, for the proper administration of
the Plan, and to amend, modify or rescind any such rules and regulations, and to
make such determinations and interpretations under, or in connection with, the
Plan, as it deems necessary or advisable. All such rules, regulations,
determinations and interpretations shall be binding and conclusive upon the
Company, its shareholders and all employees, and upon their respective legal
representatives, beneficiaries, successors and assigns and upon all other
persons claiming under or through any of them.

           No member of the Board or the Committee shall be liable for any
action or determination made in good faith with respect to the Plan or any
Option granted under it.

                             SECTION 3 - Eligibility

           The class of employees who shall be eligible to receive Options under
the Plan shall be the Key Employees (including any directors who also are
officers or are other key employees of the Company and/or of a Related
Corporation). More than one Option may be granted to a Key Employee under the
Plan. Non-Employee Directors shall be eligible to receive NQSOs, and not ISOs,
under the Plan. More than one NQSO may be granted to a Non-Employee Director
under the Plan.

                                SECTION 4 - Stock

           Options may be granted under the Plan to purchase up to a maximum of
nine hundred thousand (900,000) shares of the Company's Common Stock, subject to
adjustment as hereinafter provided; provided, however, that no Key Employee
shall receive Options for more than one hundred thousand (100,000) shares of
Common Stock over any one (1) year period; and further provided that no shares
shall be issuable pursuant to Options for which shareholder approval is not
obtained if shareholder approval is required by applicable securities laws or by
any exchange on which Common Stock is then listed. Shares issuable under the
Plan may be authorized but unissued shares or reacquired shares, and the Company
may purchase shares required for this purpose, from time to time, if it deems
such purchase to be advisable.

           If any Option granted under the Plan expires or otherwise terminates
for any reason whatever (including, without limitation, the Optionee's surrender
thereof) without having been exercised, the shares subject to the unexercised
portion of such Option shall continue to be available for the granting of
Options under the Plan as fully as if such shares had never been subject to an
Option; provided, however, that (a) if an Option is cancelled, the cancelled
Option is counted against the maximum number of shares for which Options may be
granted to an employee, and (b) if the Option price is reduced after the date of


                                       -4-


<PAGE>


grant, the transaction is treated as a cancellation of an Option and the grant
of a new Option for purposes of counting the maximum number of shares for which
Options may be granted to a Key Employee.

                         SECTION 5 - Granting of Options

           From time to time until the expiration or earlier suspension or
discontinuance of the Plan, the Committee may, on behalf of the Company, grant
to Key Employees and Non-Employee Directors under the Plan such Options as it
determines are warranted; provided, however, that grants of ISOs and NQSOs shall
be separate and not in tandem; and further provided that Non-Employee Directors
shall not be eligible to receive ISOs under the Plan. The granting of an Option
under the Plan shall not be deemed either to entitle the Optionee to, or to
disqualify the Optionee from, any participation in any other grant of Options
under the Plan. In making any determination as to whether a Key Employee or
Non-Employee Director shall be granted an Option and as to the number of shares
to be covered by such Option, the Committee shall take into account the duties
of the Key Employee or Non-Employee Director, his or her present and potential
contributions to the success of the Company or a Related Corporation, and such
other factors as the Committee shall deem relevant in accomplishing the purposes
of the Plan. Moreover, the Committee may provide in the Option that said Option
may be exercised only if certain conditions, as determined by the Committee, are
fulfilled.

                            SECTION 6 - Annual Limit

                  (a) ISOs. The aggregate Fair Market Value of the Common Stock
         with respect to which ISOs are exercisable for the first time by a Key
         Employee during any calendar year (under this Plan and any other ISO
         plan of the Company or a Related Corporation) shall not exceed one
         hundred thousand dollars ($100,000).

                  (b) NQSOs. The annual limit set forth above for ISOs shall not
         apply to NQSOs.

                   SECTION 7 - Terms and Conditions of Options

         The Options granted pursuant to the Plan shall expressly specify
whether they are ISOs or NQSOs; however, if the Option is not designated in the
Key Employee's Option Agreement as an ISO or NQSO, the Option shall constitute
an ISO if it complies with the terms of section 422 of the Code, and otherwise,
it shall constitute an NQSO. In addition, the Options granted pursuant to the
Plan shall include expressly or by reference the following terms and conditions,
as well as such other provisions not inconsistent with the provisions of this
Plan and, for ISOs granted under this Plan, the provisions of section 422(b) of
the Code, as the Committee shall deem desirable:

                                       -5-


<PAGE>


                  (a) Number of Shares. A statement of the number of shares to
         which the Option pertains.

                  (b) Price. A statement of the Option price which shall be
         determined and fixed by the Committee in its discretion but, in the
         case of an ISO, shall not be less than the higher of one hundred
         percent (100%) (one hundred ten percent (110%) in the case of more than
         ten percent (10%) shareholders as discussed in (k) below) of the Fair
         Market Value of the optioned shares of Common Stock, or the par value
         thereof, on the date the ISO is granted and, in the case of an NQSO,
         shall not be less than the higher of one hundred percent (100%) of the
         Fair Market Value of the optioned shares of Common Stock, or the par
         value thereof, on the date the NQSO is granted.

                  (c) Term.

                           (1) ISOs. Subject to earlier termination as provided
                  in Subsections (e), (f), (g) and (h) below and in Section 9
                  hereof, the term of each ISO shall be not more than ten (10)
                  years (five (5) years in the case of more than ten percent
                  (10%) shareholders as discussed in (k) below) from the date of
                  grant.

                           (2) NQSOs. Subject to earlier termination as provided
                  in Subsections (e), (f), (g) and (h) below and in Section 9
                  hereof, the term of each NQSO shall be not more than ten (10)
                  years and one (1) day from the date of grant.

                  (d) Exercise.

                           (1) General. Options shall be exercisable in such
                  installments and on such dates as the Committee may specify.
                  The Committee may accelerate the exercise date of any
                  outstanding Options, in its discretion, if it deems such
                  acceleration to be desirable.

                           Any Option shares, the right to the purchase of which
                  has accrued, may be purchased at any time up to the expiration
                  or termination of the Option. Exercisable Options may be
                  exercised, in whole or in part, from time to time by giving
                  written notice of exercise to the Company at its principal
                  office, to the attention of its Secretary, specifying the
                  number of shares to be purchased and accompanied by payment in
                  full of the aggregate Option price for such shares; provided
                  that no partial exercise of an Option shall be for a number of
                  shares of Common Stock having an aggregate Option price of
                  less than $1,000, unless such partial exercise applies to the
                  remaining shares available under the Option. Only full shares
                  shall be issued under the Plan, and any fractional share

                  which might otherwise be issuable upon exercise of an Option
                  granted hereunder shall be forfeited.

                           (2) Manner of Payment. The Option price shall be
                  payable:

                                    (A) In cash or its equivalent;

                                    (B) If the Committee, in its discretion, so
                           provides in the Option Agreement or, in the case of
                           Options which are not ISOs, if the Committee, in its
                           discretion, so determines at or prior to the time of
                           exercise, in whole or in part, in Company Common
                           Stock previously acquired by the Optionee, provided
                           that if such shares of Common Stock were acquired
                           through the exercise of an ISO and are used to pay
                           the Option price of an ISO, such shares have been
                           held by the Key Employee for a period of not less
                           than the holding period described in section
                           422(a)(1) of the Code on the date of exercise, or if
                           such shares of Common Stock were acquired through
                           exercise of an NQSO or of an option under a similar
                           plan or through exercise of an ISO and are used to
                           pay the Option price of an NQSO, such option was
                           granted more than six (6) months prior to the date of
                           exercise of the Option;

                                    (C) If the Committee, in its discretion, so
                           provides in the Option Agreement or, in the case of
                           Options which are not ISOs, if the Committee, in its
                           discretion, so determines at or prior to the time of
                           exercise, in whole or in part, in Company Common
                           Stock newly acquired by the Optionee upon exercise of
                           such Option (which shall constitute a disqualifying
                           disposition in the case of an Option which is an
                           ISO);

                                    (D) If the Committee, in its discretion, so
                           provides in the Option Agreement or, in the case of
                           Options which are not ISOs, if the Committee, in its
                           discretion, so determines at or prior to the time of
                           exercise, in any combination of (A), (B) and (C)
                           above; or

                                    (E) If the Committee, in its discretion, so
                           provides in the Option Agreement or, in the case of
                           Options which are not ISOs, if the Committee, in its
                           discretion, so determines at or prior to the time of
                           exercise, by permitting the Optionee to deliver a
                           properly executed notice of exercise of the Option to
                           the Company and a broker, with irrevocable
                           instructions to the broker promptly to deliver to the
                           Company the amount of sale or loan proceeds necessary
                           to pay the exercise price of the Option.

                           In the event such Option price is paid, in whole or
                  in part, with shares of Common Stock, the portion of the
                  Option price so paid shall be equal to the Fair Market Value
                  on the date of exercise of the Option of the Common Stock
                  surrendered in payment of such Option price.

                  (e) Termination of Employment or Board Membership for Cause.
         If a Key Employee's employment by the Company (and Related
         Corporations) or a Non-Employee Director's service as a director is
         terminated for Cause, all rights of any kind under any Option then held
         by such Optionee shall immediately lapse and terminate. For purposes of
         this Subsection (e), "Cause" shall include, without limitation, the
         following, not corrected after notice and a reasonable opportunity to
         cure:

                           (1) Dishonesty;

                           (2) Fraud, theft or misappropriation or embezzlement
                  of Company funds;

                           (3) Conviction of any felony, crime involving fraud
                  or misrepresentation, or of any other crime (whether or not
                  connected with the Optionee's employment) the effect of which
                  is likely to adversely affect the Company or its affiliates;

                           (4) Material breach of the Optionee's obligations
                  under the Optionee's employment agreement with the Company (if
                  any);

                           (5) Repeated and consistent failure of Optionee to be
                  present at work during normal business hours unless the
                  absence is because of a disability;

                           (6) Willful violation of any express direction or any
                  rule or regulation established by the Company or its Chief
                  Executive Officer;

                           (7) Gross incompetence in the performance of, or
                  gross neglect of, Optionee's duties under Optionee's
                  employment agreement with the Company (if any);

                           (8) Illegal possession or use of any controlled
                  substance; or

                           (9) Use of alcohol or other drugs which interferes
                  with the performance by Optionee of his or her duties.

                  (f) Termination of Employment or Board Membership for A Reason
         Other Than Cause, Death or Disability. If a Key Employee's employment
         by the Company (and Related Corporations) or a Non-Employee Director's
         service as a director is terminated by either party prior to the
         expiration date fixed for his or her Option for any reason other than
         Cause (as defined in Subsection (e)), death or disability, such Option
         may be exercised, to the extent of the number of shares with respect to
         which the Optionee could have exercised it on the date of such
         termination, or to any greater extent permitted by the Committee, by
         the Optionee at any time prior to the earlier of:

                           (1) The expiration date specified in such Option; or

                           (2) An accelerated termination date determined by the
                  Committee, in its discretion, except that, subject to Section
                  9 hereof, such accelerated termination date shall not be
                  earlier than the date of the Key Employee's termination of
                  employment or the date the Non-Employee Director ceases to
                  serve as a director, and in the case of ISOs, such termination
                  date shall not be later than three (3) months after the date
                  of such termination of employment.

                  (g) Exercise upon Disability of Optionee. If an Optionee shall
         become disabled (within the meaning of section 22(e)(3) of the Code)
         during his or her employment or Board membership and, prior to the
         expiration date fixed for his or her Option, his or her employment or
         service as a director is terminated as a consequence of such
         disability, such Option may be exercised, to the extent of the number
         of shares with respect to which the Optionee could have exercised it on
         the date of such termination, or to any greater extent permitted by the
         Committee, by the Optionee at any time prior to the earlier of:

                           (1) The expiration date specified in such Option; or

                           (2) An accelerated termination date determined by the
                  Committee, in its discretion, except that, subject to Section
                  9 hereof, such accelerated termination date shall not be
                  earlier than the date of the Optionee's termination of
                  employment or service as a director by reason of disability,
                  and in the case of ISOs, such date shall not be later than one
                  (1) year after the date of such termination of employment. In
                  the event of the Optionee's legal disability, such Option may
                  be so exercised by the Optionee's legal representative.

                  (h) Exercise upon Death of Optionee. If an Optionee shall die
         during his or her employment or service as a director, and prior to the
         expiration date fixed for his or her Option, or if an Optionee whose
         employment or service as a director is terminated for any reason other
         than Cause (as defined in Subsection (e)), shall die following his or
         
                                       -9-

         her termination of employment or service as a director but prior to the
         earliest of:

                           (1) The expiration date fixed for his or her Option;

                           (2) The expiration of the period determined under
                  Subsections (f) and (g) above; or

                           (3) In the case of an ISO, three (3) months following
                  termination of employment, such Option may be exercised, to
                  the extent of the number of shares with respect to which the
                  Optionee could have exercised it on the date of his or her
                  death, or to any greater extent permitted by the Committee, by
                  the Optionee's estate, personal representative or beneficiary
                  who acquired the right to exercise such Option by bequest or
                  inheritance or by reason of the death of the Optionee, at any
                  time prior to the earlier of:

                                    (A) The expiration date specified in such
                           Option; or

                                    (B) An accelerated termination date
                           determined by the Committee, in its discretion except
                           that, subject to Section 9 hereof, such accelerated
                           termination date shall not be earlier than six (6)
                           months, nor later than one (1) year after the date of
                           death.

                  (i) Non-Transferability.

                           (1) ISOs. No ISO shall be assignable or transferable
                  by the Key Employee otherwise than by will or by the laws of
                  descent and distribution, and during the lifetime of the Key
                  Employee, the ISO shall be exercisable only by him or her or
                  by his or her guardian or legal representative. If the Key
                  Employee is married at the time of exercise and if the Key
                  Employee so requests at the time of exercise, the certificate
                  or certificates shall be registered in the name of the Key
                  Employee and the Key Employee's spouse, jointly, with right of
                  survivorship.

                           (2) NQSOs. Except as otherwise provided in any Option
                  Agreement, no NQSO shall be assignable or transferable by the
                  Optionee otherwise than by will or by the laws of descent and
                  distribution, and during the lifetime of the Optionee, the
                  NQSO shall be exercisable only by him or her or by his or her
                  guardian or legal representative. If the Optionee is married
                  at the time of exercise and if the Optionee so requests at the
                  time of exercise, the certificate or certificates shall be
                  registered in the name of the Optionee and the Optionee's
                  spouse, jointly, with right of survivorship.

<PAGE>


                  (j) Rights as a Shareholder. An Optionee shall have no rights
         as a shareholder with respect to any shares covered by his or her
         Option until the issuance of a stock certificate to him or her for such
         shares.

                  (k) Ten Percent Shareholder. If the Key Employee owns more
         than ten percent (10%) of the total combined voting power of all shares
         of stock of the Company or of a Related Corporation at the time an ISO
         is granted to such Key Employee, the Option price for the ISO shall be
         not less than one hundred ten percent (110%) of the Fair Market Value
         of the optioned shares of Common Stock on the date the ISO is granted,
         and such ISO, by its terms, shall not be exercisable after the
         expiration of five (5) years from the date the ISO is granted. The
         conditions set forth in this Subsection (k) shall not apply to NQSOs.

                  (l) Listing and Registration of Shares. If at any time the
         Committee shall determine, in its discretion, that the listing,
         registration or qualification of the shares covered by an Option upon
         any securities exchange or under any state or federal law, or the
         consent or approval of any governmental regulatory body, is necessary
         or desirable as a condition of, or in connection with, the granting of
         such Option or the purchase of shares thereunder, the Company shall use
         its best efforts to effect or obtain such listing registration,
         qualification, consent or approval as soon as practicable. If such
         listing registration, qualification, consent or approval is not
         effected or obtained, no Option may be exercised, in whole or in part,
         unless and until action shall have been taken by the Company or by the
         Optionee in order to obtain an exemption from any such requirement,
         under conditions acceptable to the Committee. Without limiting the
         generality of the foregoing, each Optionee or his or her legal
         representative or beneficiary may also be required to give satisfactory
         assurance that shares purchased upon exercise of an Option are being
         purchased for investment and not with a view to distribution, and
         certificates representing such shares may be legended accordingly.

                  (m) Withholding and Use of Shares to Satisfy Tax Obligations.
         The obligation of the Company to deliver shares of Common Stock upon
         the exercise of any Option shall be subject to applicable federal,
         state and local tax withholding requirements.

                  If the exercise of any Option is subject to the withholding
         requirements of applicable federal, state and/or local tax laws, the
         Committee, in its discretion (and subject to such withholding rules
         ("Withholding Rules") as shall be adopted by the Committee), may permit
         the Key Employee to satisfy the minimum required federal, state and/or
         local withholding tax, in whole or in part, by electing to have the
         Company withhold (or by returning to the Company) shares of Common
         Stock, which shares shall be valued, for this purpose, at their Fair
         Market Value on the date of exercise of the Option (or if later, the
         
                                      -11-


<PAGE>



         date on which the Optionee recognizes ordinary income with respect to
         such exercise) (the "Determination Date"). An election to use shares of
         Common Stock to satisfy tax withholding requirements must be made in
         compliance with and subject to the Withholding Rules. The Committee may
         not withhold shares in excess of the number necessary to satisfy the
         minimum federal, state and local income tax withholding requirements.
         In the event shares of Common Stock acquired under the exercise of an
         ISO are used to satisfy such withholding requirement, such shares of
         Common Stock must have been held by the Key Employee for a period of
         not less than the holding period described in section 422(a)(1) of the
         Code on the Determination Date.

                SECTION 8 - Option Agreements - Other Provisions

         Options granted under the Plan shall be evidenced by written Option
Agreements in such form as the Committee shall, from time to time, approve,
which Option Agreements shall contain provisions (such as, but not limited to,
non-compete provisions), not inconsistent with the provisions of the Plan (for
Options) and not inconsistent with section 422(b) of the Code (for ISOs), as the
Committee shall deem advisable, and which Option Agreements shall specify
whether the Option is an ISO or NQSO; provided, however, if an Option granted to
a Key Employee is not designated in the Option Agreement as an ISO or NQSO, the
Option shall constitute an ISO if it complies with the terms of section 422 of
the Code, and otherwise, it shall constitute an NQSO. Each Optionee shall enter
into, and be bound by, such Option Agreement.

                         SECTION 9 - Capital Adjustments

         The number of shares which may be issued under the Plan, and the
maximum number of shares with respect to which options may be granted during a
specified period to any Key Employee under the Plan, as stated in Section 4
hereof, and the number of shares issuable upon exercise of outstanding Options
under the Plan (as well as the Option price per share under such outstanding
Options), shall, subject to the provisions of section 424(a) of the Code, be
adjusted, as may be deemed appropriate by the Committee, to reflect any stock
dividend, stock split, share combination, or similar change in the
capitalization of the Company. 

         In the event of a corporate transaction (as that term is described in
section 424(a) of the Code and the Treasury Regulations issued thereunder as,
for example, a merger, consolidation, acquisition of property or stock,
separation, reorganization, or liquidation), each outstanding Option shall be
assumed by the surviving or successor corporation or by a parent or subsidiary
of such corporation if such corporation is the employer corporation (as provided
in section 424(a) of the Code and the regulations thereunder); provided,
however, that, in the event of a proposed corporate transaction, the Committee
may terminate all or a portion of the outstanding Options if it determines that
such termination is in the best interests of the Company. If the Committee

                                      -12-


<PAGE>


decides to terminate outstanding Options, the Committee shall give each Optionee
holding an Option to be terminated not less than seven (7) days' notice prior to
any such termination by reason of such a corporate transaction, and any such
Option which is to be so terminated may be exercised (if and only to the extent
that it is then exercisable) up to, and including the date immediately preceding
such termination. Further, as provided in Section 7(d) hereof the Committee, in
its discretion, may accelerate, in whole or in part, the date on which any or
all Options become exercisable.

         The Committee also may, in its discretion, change the terms of any
outstanding Option to reflect any such corporate transaction, provided that, in
the case of ISOs, such change is excluded from the definition of a
"modification" under section 424(h) of the Code.

                         SECTION 10 - Change in Control

         Notwithstanding any other provision of this Plan, all outstanding
Options shall become fully vested and exercisable upon a Change in Control. For
purposes of this Section 10, a "Change in Control" of the Company shall be
deemed to have occurred if:

         (a) any person (a "Person"), as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(other than (i) the Company and/or its wholly-owned subsidiaries, (ii) members
of the Rotko Family, as defined below, (iii) any ESOP or other employee benefit
plan of the Company, and any trustee or other fiduciary in such capacity holding
securities under such employee plan, (iv) any corporation owned, directly or
indirectly, by the shareholders of the Company in substantially the same
proportions as their ownership of stock of the Company), is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Company representing 30% or more of the
combined voting power of the Company's then outstanding securities; or

         (b) the Company's shareholders or the Company's directors shall approve
(i) any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which the Company's voting
common shares (the "Common Shares") would be converted into cash, securities or
other property, other than a merger of the Company in which holders of Common
Shares immediately prior to the merger have the same proportionate ownership of
common shares of the surviving corporation immediately after the merger as
immediately before, (ii) any sale, lease, exchange or other transfer (in one
transaction or series of related transactions) of all or substantially all the
assets or earning power of the Company, or (iii) the liquidation or dissolution
of the Company.

                                      -13-

         As used in this Section 10, "members of the Rotko Family" shall mean
the wife, children and grandchildren of the late Bernard Rotko, their respective
spouses and estates and any trusts primarily for the benefit of any of the
foregoing.

              SECTION 11 - Amendment or Discontinuance of the Plan

                  (a) General. The Board from time to time may suspend or
         discontinue the Plan or any outstanding Option, or amend the Plan or
         any outstanding Option in any respect whatsoever, except that the
         following amendments shall require shareholder approval (given in the
         manner set forth in Section 11(b) below):

                  (1) With respect to ISOs, any amendment which would:

                           (A) Change the class of employees eligible to
                  participate in the Plan;

                           (B) Except as permitted under Section 9 hereof,
                  increase the maximum number of shares of Common Stock with
                  respect to which ISOs may be granted under the Plan; or

                           (C) Extend the duration of the Plan under Section 12
                  hereof with respect to any ISOs granted hereunder;

                  (2) With respect to Options, any amendment which would require
         shareholder approval pursuant to Treas. Reg. ss. 1.162-27(e)(4)(vi) (or
         any successor thereto) (to the extent compliance with section 162(m) of
         the Code is desired); and

                  (3) With respect to Options, any amendment which would require
         shareholder approval under the rules of an exchange or market on which
         Common Stock is traded or listed.

         Notwithstanding the foregoing, no such suspension, discontinuance or 
    amendment shall materially impair the rights of any holder of an outstanding
    Option without the consent of such holder.

         (b) Shareholder Approval Requirements.  Shareholder approval must meet
    the following requirements:

                  (1) The approval of shareholders must be by a majority of the
         outstanding shares of Common Stock present, or represented, and
         entitled to vote at a meeting duly held in accordance with the
         applicable laws of the State of Delaware; and 

                                      -14-


<PAGE>




                  (2) The approval of shareholders must comply with all
         applicable provisions of the corporate charter, bylaws, and applicable
         state law prescribing the method and degree of shareholder approval
         required for the issuance of corporate stock or options. If the
         applicable state law does not prescribe a method and degree of
         shareholder approval in such case, the approval of shareholders must be
         effected:

                           (A) By a method and in a degree that would be treated
                  as adequate under applicable state law in the case of an
                  action requiring shareholder approval (i.e., an action on
                  which shareholders would be entitled to vote if the action
                  were taken at a duly held shareholders' meeting); or

                           (B) By a majority of the votes cast at a duly held
                  shareholders' meeting at which a quorum representing a
                  majority of all outstanding voting stock is, either in person
                  or by proxy, present and voting on the plan.

                        SECTION 12 - Termination of Plan

         Unless earlier terminated as provided in the Plan, the Plan and all
authority granted hereunder shall terminate absolutely at 12:00 midnight on June
22, 2007, which date is within ten (10) years after the date the Plan was
adopted by the Board (or the date the Plan was approved by the shareholders of
the Company, whichever is earlier), and no Options hereunder shall be granted
thereafter. Nothing contained in this Section 12, however, shall terminate or
affect the continued existence of rights created under Options issued hereunder
and outstanding on June 22, 2007, which by their terms extend beyond such date.

                        SECTION 13 - Shareholder Approval

         This Plan shall become effective on June 23, 1997; provided, however,
that if the Plan is not approved by the shareholders in the manner described in
Section 11(b), within twelve (12) months before or after said date, no further
Options shall be granted under the Plan, and any ISOs granted under the Plan
shall be null and void.

                           SECTION 14 - Miscellaneous

                  (a) Governing Law. With respect to any ISOs granted pursuant
         to the Plan and the Option Agreements thereunder, the Plan, such Option
         Agreements and any ISOs granted pursuant thereto shall be governed by
         the applicable Code provisions to the maximum extent possible.
         Otherwise, the operation of, and the rights of Optionees under, the
         Plan, the Option Agreements and any Options granted thereunder shall be
         governed by applicable federal law and otherwise by the laws of the
         State of Delaware.

                  (b) Rights. Neither the adoption of the Plan nor any action of
         the Board or the Committee shall be deemed to give any individual any
         right to be granted an Option, or any other right hereunder, unless and
         until the Committee shall have granted such individual an Option, and
         then his or her rights shall be only such as are provided by the Option
         Agreement.

                  Any Option under the Plan shall not entitle the holder thereof
         to any rights as a shareholder of the Company prior to the exercise of
         such Option and the issuance of the shares pursuant thereto. Further,
         notwithstanding any provisions of the Plan or the Option Agreement with
         an Optionee, the Company shall have the right, in its discretion, to
         retire an Optionee at any time pursuant to its retirement rules or
         otherwise to terminate his or her employment at any time for any reason
         whatsoever.

                  (c) Indemnification of Board and Committee. Without limiting
         any other rights of indemnification which they may have from the
         Company and any Related Corporation, the members of the Board and the
         members of the Committee shall be indemnified by the Company against
         all costs and expenses reasonably incurred by them in connection with
         any claim, action, suit, or proceeding to which they or any of them may
         be a party by reason of any action taken or failure to act under, or in
         connection with, the Plan, or any Option granted thereunder, and
         against all amounts paid by them in settlement thereof (provided such
         settlement is approved by legal counsel selected by the Company) or
         paid by them in satisfaction of a judgment in any such action, suit, or
         proceeding, except a judgment based upon a finding of willful
         misconduct or recklessness on their part. Upon the making or
         institution of any such claim, action, suit, or proceeding, the Board
         or Committee member shall notify the Company in writing, giving the
         Company an opportunity, at its own expense, to handle and defend the
         same before such Board or Committee member undertakes to handle it on
         his or her own behalf.

                  (d) Application of Funds. The proceeds received by the Company
         from the sale of Common Stock pursuant to Options granted under the
         Plan shall be used for general corporate purposes. Any cash received in
         payment for shares upon exercise of an Option to purchase Common Stock
         shall be added to the general funds of the Company and shall be used
         for its

                                      -16-


<PAGE>



         corporate purposes. Any Common Stock received in payment for shares
         upon exercise of an Option to purchase Common Stock shall become
         treasury stock.

                  (e) No Obligation to Exercise Option. The granting of an
         Option shall impose no obligation upon an Optionee to exercise such
         Option.

         IN WITNESS WHEREOF, MEDIQ Incorporated has caused these presents to be
duly executed, under seal, this [ ] day of June, 1997.

         The parties hereto desire to set forth the terms of Executive's
transition from MEDIQ by extending through September 30, 1998 the term of
Executive's employment pursuant to the Employment Agreement on the terms and
conditions as set forth therein, except as amended hereby.

         NOW THEREFORE, in consideration of the premises and intending to be
legally bound hereby, the parties hereto agree as follows:

         1. Section 1.2 of the Employment Agreement is hereby amended to read in
its entirety as follows:

         1.2 Capacity and Duties.

             (a) Executive resigns all of his positions as an officer of MEDIQ
             and as an officer or director of any subsidiary of MEDIQ as of

             (b) During the term of his employment hereunder, Executive shall
             perform such services for MEDIQ and its subsidiaries as may
             reasonably be assigned to him, from time to time, by the Chief
             Executive Officer of MEDIQ (the "CEO"). Such duties may include,
             without limitation, the following:

                   (i) advising, consulting and assisting in transition matters
                  relating to the transfer of responsibilities to a successor
                  Senior Vice President of Finance and Chief Financial Officer;

                  (ii) advising, consulting and assisting in such other business
                  matters as requested by the CEO.

             Unless expressly authorized by MEDIQ's Board of Directors or the
             CEO, Executive shall not have, and shall not hold himself out as
             having, any


<PAGE>


             authority to make any representations on behalf of MEDIQ nor to
             execute any agreements on behalf of MEDIQ or otherwise to bind
             MEDIQ to any obligation to third parties.

             During the term of his employment hereunder, Executive shall not be
             required to spend more than 45 hours per month on the performance
             of his duties. Executive shall record the time spent by him on the
             duties assigned by the CEO and shall submit a statement of such
             time to the CEO, upon request from the CEO. Further, such duties
             may be performed via telephone and/or by written communication and
             shall not require Executive's presence at MEDIQ's facilities or his
             travel outside of the greater Philadelphia area unless otherwise
             mutually agreed by the parties.

         2.  Section 2.1 of the Employment Agreement is hereby amended to read
in its entirety as follows:

         2.1 Term. The term of Executive's employment hereunder shall continue
         through September 30, 1998, upon which such employment shall terminate
         without notice or further action by any party. The one-year period
         beginning October 1, 1997 and ending September 30, 1998 is referred to
         herein as the "Contract Period."

         3.  Sections 3.1, 3.2, 3.3 and 3.4 of the Employment Agreement are
hereby amended to read in their entirety as follows:

         3.1 Basic Compensation. As compensation for Executive's services
         hereunder, during the Contract Period MEDIQ shall pay to Executive a
         salary at the annual rate in effect for Executive as of September 1,
         1997 (the "Base Salary"). Such Base Salary shall be payable throughout
         the Contract Period in accordance with MEDIQ's regular payroll
         practices in effect from time to time, less applicable withholding and
         deductions.

         3.2 Performance Bonus. Any performance bonus due to Executive pursuant
         to Section 3.2 of the Agreement as in effect prior to this Third
         Amendment that is earned or accrued as of September 30, 1997 (as
         determined in accordance with GAAP), shall be payable to Executive in
         accordance with the corporate policies of MEDIQ. No performance bonus
         shall be payable to Executive with respect to fiscal years beginning
         after September 30, 1997.

             (a) General Rule Regarding Benefits During Contract Period. Except
             as otherwise provided in this Section 3.3, Executive shall be
             entitled during the Contract Period to participate in all of

             time to time be provided for employees of MEDIQ whose duties,

             those of Executive prior to October 1, 1997.

             (b) Vacation. Payment for all accrued vacation pay owed to
             Executive as of September 30, 1997 shall be made by MEDIQ to

                                    AMENDMENT


         THIS AMENDMENT to the Employment Agreement between MEDIQ Incorporated
(the "Company"), MEDIQ/PRN Life Support Services, Inc. ("MEDIQ/PRN") and Thomas
Carroll (the "Executive"), dated as of April 27, 1995 (the "Original
Agreement"), is made by and between the Company, MEDIQ/PRN and the Executive as
of November 14, 1997.

                                   BACKGROUND



         The Board of Directors of the Company (the "Board") has initiated a
process to examine certain strategic alternatives designed to enhance the
Company's value to its stockholders. Executive is the President and Chief
Executive Officer of the Company and as such his active participation and
involvement in this process is crucial to its success. In addition, the Company
has determined that it is in its best interests to obtain the Executive's
agreement to forego, under certain circumstances, any payments to him under
Section 3.6(c) of the Original Agreement and also to extend the duration of his
covenant not to compete with the Company following termination of his
employment, and also to extend the term of the Agreement. In consideration of
the Success Bonus provided for herein, the Executive is willing to extend the
term of this agreement and the duration of his non-competition agreements, as
well as to forego any payments under Section 3.6(c), as and to the extent
provided herein. Subject to the foregoing, the Executive is also willing to
actively participate in the strategic process being undertaken by the Board.

         The parties hereto therefore desire to amend the Original Agreement in
certain respects (which agreement, as amended hereby, is referred to as the
Employment Agreement).

     NOW THEREFORE, in consideration of the premises and intending to be legally
bound hereby, the parties hereto agree as follows:

         1. Section 3.4 of the Original Agreement is hereby amended to read in
its entirety as follows:

         3.4 Success Bonus.

             (a) Executive has agreed to cooperate with the Board in analyzing
and pursuing various strategic alternatives, designed to enhance stockholder
value. If, before June 30, 1998, a Strategic Transaction (as hereafter defined)
occurs, Executive shall be entitled to receive a one-time bonus calculated as
provided in paragraph (b) below. For the purposes of this Agreement, a


                                     - 1 -
<PAGE>


"Strategic Transaction" means any sale or divestiture of MEDIQ or MEDIQ/PRN,
including (i) a sale of substantially all of its stock (including through
merger, tender, exchange or otherwise) or assets, in either case in one or more
related transactions, (ii) a Change in Control (as defined below) and (iii) any
sale or distribution of the stock of MEDIQ or MEDIQ/PRN which results in a
Change in Control at the time of such sale or distribution or at any time within
the immediately succeeding twelve (12) months. Executive's bonus shall be paid
in cash within 30 days after the consummation of a Strategic Transaction.

             (b) Executive's bonus payable upon a Strategic Transaction shall
equal the sum of (i) .25% of the aggregate purchase price paid for MEDIQ or
MEDIQ/PRN up to a maximum aggregate purchase price of $375,000,000 plus (ii) if
the aggregate purchase price paid for MEDIQ or MEDIQ/PRN exceeds $375,000,000,
1.5% of any purchase price in excess of $375,000,000. For purposes of
calculating the bonus, the aggregate purchase price shall equal the sum of (x)
the total cash consideration paid (including, without limitation, in respect of
any warrants or other security of MEDIQ or MEDIQ/PRN), plus (y) the fair market
value of any securities or other property received as consideration (including,
without limitation, in respect of any warrants or other security of MEDIQ or
MEDIQ/PRN), plus (z) the aggregate amount (including, without limitation,
accrued but unpaid interest and the unpaid amount of any capital leases) of any
aggregate liabilities assumed or refinanced by the purchaser in connection with
the completion of the acquisition, other than current liabilities taken into
account in computing the working capital (except for current liabilities for
indebtedness for money borrowed (including accrued but unpaid interest or
capital leases)). The aggregate purchase price on which Executive's bonus is to
be calculated is hereafter called "Enterprise Value." In the event of any
dispute between Executive and MEDIQ regarding the Enterprise Value on which
Executive's bonus shall be calculated, the Directors and Executive shall select
an investment banking firm, reasonably acceptable to each of them, to make the
determination of the Enterprise Value. The fees and expenses of the investment
banking firm incurred in making such determination shall be borne by MEDIQ,
unless the investment banking firm shall determine that the Executive's position
regarding the calculation of Enterprise Value was unreasonable under the
circumstances, in which case such fees and expenses shall be shared equally
between MEDIQ and Executive.

             (c) Executive acknowledges that a Strategic Transaction may not
occur, that the Board of Directors may determine not to pursue a Strategic
Transaction, that such a transaction can occur only upon proper authorization of
the Board of Directors, or a duly constituted committee thereof, and accordingly
there can be no assurance that any bonus will become payable to Executive under
this Section.

             (d) [Omitted]

             (e) For purposes of Section 3.4 of this Agreement a "Change in
Control" shall mean the earlier of such time as (i) the Rotko Group collectively
ceases to beneficially own more than 35% of the voting power held by all
stockholders of MEDIQ (or MEDIQ/PRN, as the case may be) or (ii) the Rotko Group


                                     - 2 -
<PAGE>


collectively ceases to beneficially own more than 50% of the voting power held
by all stockholders of MEDIQ (or MEDIQ/PRN, as the case may be) and none of
MEDIQ's securities are registered pursuant to Section 12 of the Securities
Exchange Act of 1934, as amended.

                  2. Section 3.6(a) and the first four sentences of Section
3.6 (c)(ii) of the Original Agreement are hereby amended to read in their
entirety as follows:


                          "(a) If a Strategic Transaction occurs before June 30,
             1998 and the Executive thereupon becomes entitled to a bonus
             payment under Section 3.4(a) of this Employment Agreement, the
             Executive shall forfeit all rights to any stock appreciation right
             compensation granted pursuant to Section 3.6 of the Original
             Agreement, and shall be entitled in lieu thereof solely to the
             bonus payable under such Section 3.4(a) (and to the stock options
             granted pursuant to Section 3.6(b) of the Original Agreement)."

                                            *    *      *   *

                          "(ii) Except as provided in clause (iv) below, upon
             the termination of Executive's employment for any reason, Executive
             shall, subject to Section 3.6(a), be entitled to be paid the value
             of his SARs (granted pursuant to Section 3.6(c)(i)) in cash.
             Payment of the value of Executive's SARs shall be made within 120
             days of the termination of his employment. In addition, subject to
             Section 3.6(a), Executive may, at his option, request payment of
             the value of his SARs at the time of such request, in whole or in
             part, on each fifth anniversary of the date of this Agreement and
             such request(s) shall not result in cancellation of such SARs
             ("Payment Request"). The value of Executive's SARS to be paid to
             him (or his estate) upon the termination of his employment (or any
             earlier request) as provided above shall be the amount obtained by
             solving the following formula:" (The remainder of Section
             3.6(c)(ii) is not being amended hereby and shall continue in full
             force and effect as provided in the Original Agreement)


             3. Section 2.1 of the Original Agreement is hereby amended to read
in its entirety as follows:

             The term of Executive's employment hereunder shall continue until
             November 14, 1999 (the second anniversary of the date of the First
             Amendment to the Original Agreement) and shall thereafter
             automatically be renewed for successive two-year terms unless and
             until either party shall give notice of his or its election to
             terminate Executive's employment at least 60 days before the end of
             the then current term, unless earlier terminated as provided herein
             (the "Contract Period").


             4. Section 5.2(a) of the Original Agreement is hereby amended to
provide that the period of time referred to in the third line of the first
sentence of such section shall be two years, instead of one year, as provided in
the Original Agreement.


                                     - 3 -

             5. Except as expressly modified herein, all other terms and
conditions set forth in the Original Agreement shall remain in full force and
effect. The parties may, but shall not be required to, execute a conformed
version of the Employment Agreement, incorporating the amendments to the
Original Agreement effect hereby. This Amendment may be executed in
counterparts, each of which shall be deemed to be an original but all of which
shall constitute one and the same agreement. Facsimile signatures shall be
treated as originals for all purposes hereunder.

             6. This amendment has been duly authorized, executed and delivered
by each of the parties hereto in accordance with Section 6.6 of the Original
Agreement.

         IN WITNESS WHEREOF, the parties have executed this Amendment as of the
14 day of November, 1997.
