ITEM 1.   BUSINESS

Introduction

Company Profile
- ---------------

Mallinckrodt Inc. (Mallinckrodt or the Company) is a global company
serving selected healthcare markets with products used primarily for
respiratory care, diagnostic imaging and pain relief.

The Company was incorporated in New York in 1909 under the name
International Agricultural Corporation.  The corporate headquarters is
located at 675 McDonnell Boulevard, St. Louis, Missouri 63134, and the
telephone number is (314) 654-2000.

Transformation of the Company
- -----------------------------

During the past several years, many significant steps have been taken
to transform the composition of the Company.  During the past three
years, the transformation has involved the following:

     -  On October 16, 1996, the shareholders approved changing the
        Company's name from Mallinckrodt Group Inc. to Mallinckrodt
        Inc.

     -  On March 31, 1997, the Company disposed of Fries & Fries,
        Inc., a wholly owned subsidiary which owned the Company's 50
        percent interest in Tastemaker, which was the flavors joint
        venture.  The transaction generated a net value to the Company
        of $550 million.

     -  On June 30, 1997, the Company sold the animal health segment
        for $405 million cash.  The Company retained certain
        liabilities.

     -  On August 28, 1997, the Company acquired Nellcor Puritan
        Bennett Incorporated (Nellcor) through an agreement to
        purchase for cash all of the outstanding shares of common
        stock of Nellcor for $28.50 per share.  The aggregate purchase
        price of the Nellcor acquisition was approximately $1.9
        billion.  Nellcor is the worldwide market leader in providing
        products that monitor, diagnose and treat respiratory impaired
        patients.

     -  During 1998, the Company sold, or committed to sell, its
        catalysts and chemical additives and Aero Systems divisions.
        These transactions generated cash proceeds of $305 million in
        1998 and $56 million in 1999.

Other recent acquisitions, divestitures and continuing investments in
each of Mallinckrodt's businesses are described in the discussions of
the business segments in Management's Discussion and Analysis of
Financial Condition and Results of Operations in Item 7, and Note 2 of
the Notes to Consolidated Financial Statements in Item 8.

- -----------------------------------------
CAUTIONARY STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM
ACT OF 1995:  Our discussion and analysis in this annual report
contain some forward-looking statements.  Forward-looking statements
do not relate strictly to historical or current facts, but rather give
our current expectations or forecasts of future events.  Forward-

General Points
- --------------

In this report:

Mallinckrodt Inc. and its subsidiaries, collectively, are called the
"Company" or "Mallinckrodt," unless otherwise indicated by the
context.  The Company has three business segments - Respiratory,
Imaging and Pharmaceuticals.

The term "operating earnings" represents revenues less all operating
expenses.  Operating expenses of a business segment do not include
interest expense, corporate income or expense, and taxes on income.

All references to years are to fiscal years ended June 30 unless
otherwise stated.

Registered and common law trademarks are indicated by an asterisk (*).

GENERAL FACTORS RELATED TO THE BUSINESS

Results from operations and related working capital requirements for
Mallinckrodt's Respiratory and Pharmaceuticals business segments are
materially affected by seasonal factors primarily related to the
common cold and influenza season.  These seasonal factors tend to
favorably affect sales and earnings of ventilators and pulse oximetry
products (Respiratory), bulk and dosage narcotics, and acetaminophen
(Pharmaceuticals) primarily in the third and fourth quarters.

Mallinckrodt's business segments generally do not extend long-term
credit to customers.  The Company does, however, periodically
facilitate leasing arrangements through unaffiliated companies for the
financing of medical equipment sales to hospital and alternate care
customers.  In certain instances, the Company provides limited
recourse to the unaffiliated company in the event of customer default;
however, the total potential liability from the recourse is immaterial
to the Company as a whole.  The Company believes this credit policy,
as well as its working capital requirements, do not materially differ
from those of its competitors.

Competition with manufacturers and suppliers in Mallinckrodt's
business segments involves price, service, quality and technological
innovation.  Competition is strong in all markets served.

The Company's operations are subject to significant U.S. and
international regulation related to the safety and efficacy of human
medical devices and pharmaceutical products, the control and safety of
radiopharmaceutical and controlled substances, and the environmental
impact of the manufacture, storage and distribution of the Company's
products.

Financial information about the business segments is in Item 7,
Management's Discussion and Analysis of Financial Condition and
Results of Operations, and in Item 8, Financial Statements and
Supplementary Data.  Financial information about foreign and domestic
operations is included in Note 18 of the Notes to Consolidated
Financial Statements in Item 8.

INTERNATIONAL AND ECONOMIC RISK FACTORS

The Company operates globally, with manufacturing and distribution
facilities in various countries, and is subject to certain
opportunities and risks, including foreign currency fluctuations and
government actions.  Various operational initiatives are employed to
help manage business risks.  In the ordinary course of business,
Mallinckrodt purchases materials and sells finished products
denominated in approximately 25 different currencies.  The Company is
primarily exposed to changes in exchange rates of the German deutsche
mark and other Euro currencies, the Japanese yen and the Australian
dollar.  Overall, the Company is a net beneficiary when the U.S.
dollar weakens and is adversely affected by a stronger U.S. dollar
relative to the major currencies identified.  To minimize exposures to
foreign currency exchange rates, which occur in the ordinary course of
business, the Company purchases currency options.

The Company's interest income and expense are most sensitive to
changes in the general level of U.S. interest rates.  In this regard,
changes in U.S. interest rates affect the interest earned on the
Company's cash equivalents and short-term investments as well as
interest paid on its short-term debt.  To manage the interest rate
characteristics of its outstanding debt to a more desirable fixed or
variable rate basis or to limit the Company's exposure to rising
interest rates, the Company periodically enters into interest rate
swaps and option contracts.

For more information on the Company's risk management strategy, see
Item 7, Management's Discussion and Analysis of Financial Condition
and Results of Operations, and Item 8, Financial Statements and
Supplementary Data.

The Company does not consider the present overall rate of inflation to
have a significant impact on the businesses in which it operates;
however, general sales price declines in hospital and alternate care
products on a global basis due to healthcare cost containment have had
a negative effect on operating results, and this trend is expected to
continue.

While future economic events cannot be predicted, the Company believes
its current operations and future expansion plans will not result in a
significantly different risk profile.

Mallinckrodt's sales to customers outside the U.S. represented
approximately 32, 33 and 36 percent of consolidated net sales in 1999,
1998 and 1997, respectively.  Products are manufactured and marketed
through a variety of subsidiaries and affiliates around the world.
For additional information, see discussions of individual business
segments included below; under Item 7, Management's Discussion and
Analysis of Financial Condition and Results of Operations; and in Item
8, Note 18 of the Notes to Consolidated Financial Statements.

OPERATIONS

The Company manufactures and distributes advanced innovative products
for acute and chronic respiratory care, imaging products for disease
diagnosis, and pharmaceutical products used in pain management.
Principal products include pulse oximetry monitors and sensors which
provide non-invasive monitoring of pulse rate and oxygen saturation,
x-ray contrast media used in radiology and cardiology procedures,
radiopharmaceuticals used in diagnostic nuclear medicine procedures,
critical care and portable ventilators, home oxygen therapy products,
airway management and other critical care devices, acetaminophen and
bulk and dosage narcotics used in pain management, and laboratory and
microelectronic chemicals.

The Company is comprised of three business segments - Respiratory,
Imaging and Pharmaceuticals.

Net sales by segment were (in millions):

                                        1999       1998       1997

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

On August 28, 1997, the Company acquired Nellcor through an agreement
to purchase for cash all of the outstanding shares of common stock of
Nellcor for $28.50 per share.  The aggregate purchase price of the
Nellcor acquisition was approximately $1.9 billion.  The combination
of Nellcor and Mallinckrodt's critical care division, which together
comprise the Respiratory segment of the Company, created the worldwide
market leader in providing products that monitor, diagnose and treat
respiratory impaired patients.  Product lines include pulse oximetry
monitors and sensors, critical care and portable ventilators, home
oxygen therapy products, sleep apnea diagnostic and therapy products,
and medical gases.

The acquisition was accounted for under the purchase method of
accounting and, accordingly, the results of operations of Nellcor have
been included in the Company's consolidated financial statements since
September 1, 1997.  The purchase price of the acquisition was
allocated to the assets acquired and liabilities assumed based upon
generally accepted accounting principles and estimated fair values at
the date of acquisition.  The excess of the purchase price over the
fair value of the net identifiable assets, totaling $814.2 million,
was allocated to goodwill and is being amortized on a straight-line
basis over 30 years.

The Company's products are instrumental in the delivery of healthcare
services and are sold to hospital and alternate care sites, clinical
laboratories, pharmaceutical manufacturers and other customers on a
worldwide basis.  Healthcare products are influenced by a high degree
of innovation and technology, by regulation from agencies such as the
U.S. Food and Drug Administration (FDA), industry standards and by
markets served.  They are significantly affected by conditions within
the healthcare industry, including continuing legislative initiatives
and public and private healthcare insurance and reimbursement
programs.  An aging population and demand for technologically superior
products to extend and improve the quality of life are two major
factors fueling growth within the industry.

The healthcare industry is experiencing extensive change.  All markets
served by the Company are highly competitive in the United States and
overseas.  Legislative bodies, in all likelihood, will continue to
review and assess alternative healthcare delivery systems and payment
methodologies, and ongoing public debate of these issues can be
expected.  Cost containment initiatives, market pressures and proposed
changes in applicable laws and regulations may significantly affect
pricing or demand for medical products, the relative costs associated
with doing business, and the amount of reimbursement by both
government and third-party payors.  In particular, the industry is
experiencing market-driven reforms from forces within the industry
that are exerting pressure on healthcare providers and product
manufacturers to reduce healthcare costs.  These market-driven reforms
are resulting in industry-wide consolidation that is expected to
increase the downward pressure on healthcare product margins, as
larger buyer and supplier groups exert pricing pressure on providers
of medical devices and other healthcare products.  Managed care and
other healthcare provider organizations have grown substantially in
terms of the percentage of the population in the United States that
receives medical benefits through such organizations and in terms of
the influence and control that they are able to exert over an
increasingly large portion of the healthcare industry.  These
organizations are continuing to consolidate and grow, which may
increase the ability of the organizations to influence the practices
and pricing involved in the purchase of medical products, including
those products sold by the Company.  Both cost containment and
regulatory reform may have an adverse impact on the Company's results
of operations.

The demand for price reductions from healthcare customer buying groups
continued throughout 1999.  This trend, which is expected to continue,
had its most significant impact on the Company's Imaging segment,
where the potential for generic competitive products and available
manufacturing capacity continue to lower prices.  In response to this
market trend, in 1996, the Company entered into a multi-year
agreement, with prices subject to periodic renegotiation, with Premier
Purchasing Partners, L.P. (Premier), the largest healthcare purchasing
group in the United States.  Effective July 1, 1997, Premier named
Mallinckrodt a corporate partner and, accordingly, Premier's 1,800
hospital and healthcare facilities are provided incentives to use
Mallinckrodt products.  Effective July 1, 1999, the corporate
partnership agreement was extended two years through December 31,
2006, and the agreement now includes almost all Respiratory and
Imaging segment products.  For 1999, 1998 and 1997, net sales to
hospital and healthcare facilities under the Premier agreement
represented approximately 13 percent, 13 percent and 9 percent of net
sales, respectively.  No individual customer, either through Premier
or otherwise, represented more than 10 percent of net sales for any of
the three years in the period ended June 30, 1999.

With the acquisition of Nellcor in August 1997, Mallinckrodt is a more
significant supplier to healthcare providers.  Customers will benefit
from the combined companies' expanded product lines and strengthened
position as a full service, single source for hospitals and national
and regional purchasing organizations.

See Item 7, Management's Discussion and Analysis of Financial
Condition and Results of Operations; and Item 8, Note 2 of Notes to
Consolidated Financial Statements for additional information about
business activities.

Respiratory
- -----------

The Respiratory segment develops and markets products that help
diagnose, monitor and treat respiratory disorders, wherever patients
receive care.  Nellcor, with its core competency in pulse oximetry,
joined with Puritan-Bennett Corporation, the leader in critical care
ventilation, in 1995.  Mallinckrodt had previously established world
leadership positions in airway management and other critical care
devices.

Today, the Company's product line is the broadest in the industry and
is composed of several businesses - anesthesia and respiratory
devices; oximetry, including monitors and sensors; critical care and
portable ventilators; medical gas; oxygen therapy and asthma
management; sleep diagnostics and therapy; blood analysis products;
and maintenance services.

Anesthesia and respiratory devices include continuous core temperature
monitoring systems, fluid warming and convective warm air temperature
management systems, and endotracheal and tracheostomy tubes.
Continuous core temperature monitoring and temperature management
systems are utilized both in surgical procedures and post-operatively.
The airway management product line consists of basic and specialty
tracheal tubes, a full range of disposables used in hospitals to
connect the airway management products to anesthesia and ventilation
machines, and tracheostomy tubes which are used in hospitals and
alternate site facilities for maintaining airways during respiratory
care.  The Company's endotracheal and tracheostomy tubes are by far
the world market leaders.

Mallinckrodt is the world's foremost manufacturer of oximetry
products, including monitors and sensors.  The Company has built on
its expertise in pulse oximetry to offer a wide range of patient
safety products for clinical assessment in every healthcare setting
and the home.  From simple handheld devices to multiparameter systems,
the Nellcor line offers choice in size, cost and function.  Today,
Mallinckrodt offers the most comprehensive line of adhesive and
reusable sensors for all patient types and applications.  Oximetry
product sales were 14 percent and 12 percent of Mallinckrodt's
consolidated sales for 1999 and 1998, respectively.

The Company's OEM oximetry modules are sold to manufacturers of
multiparameter monitoring systems, which incorporate the Company's
oximetry technology into their own systems.  Mallinckrodt currently
has agreements with 78 OEMs and licensees.  These customers include
medical equipment manufacturers in the United States, Europe, Asia,
Japan and Latin America.

The Company entered into agreements with Hewlett Packard Company (HP)
in 1996 and Corometrics, Inc. in 1995 to incorporate the Company's
fetal oximetry technology into integrated maternal fetal monitors
provided by these leading suppliers.  Both HP and Corometrics, Inc.
are currently selling these integrated monitors outside of the United
States.

During 1999, Mallinckrodt received 510(k) clearance for new oximetry
products, including the NPB-3900* Series Multiparameter Monitors and
the NPB-4000C* Multiparameter Monitor with Color Display.  The latest
addition to the oximetry family, the NPB-395* Pulse Oximeter, is
pending 510(k) clearance.

The Company's fetal pulse oximeter is already approved in Europe and
is in the advanced stages of product registration in the United
States.  It is believed that the N-400* Fetal Oximetry System will
help lower the risks involved in childbirth by reducing unnecessary
cesarean section deliveries.  The Company believes that fetal pulse
oximetry can help clinicians make more informed decisions regarding
the status of a fetus during labor and delivery by providing
information that helps them determine if the fetus is adequately
oxygenated when the heart-rate pattern is non-reassuring.

During 1999, the Company introduced the MP404* Oximetry Module.  With
this module installed, OEM customers can have advanced digital signal
processing designed to tenaciously track patient oxygen status, even
during long periods of patient motion or poor perfusion.  Upgraded
algorithms allow the MP404* to read through signal corruption to
provide accurate patient saturation and pulse values.  This makes the
MP404* ideal for use in monitoring neonatal through adult patients in
a variety of settings.

The critical care and portable ventilators business currently offers
the world's most popular ventilator, the Puritan-Bennett 7200*
ventilator system.  The 7200* Series ventilator system is a critical
care ventilator purchased primarily by hospitals to assist or manage
patient respiration in a variety of acute care settings.  The 7200*
Series ventilator is designed to ease the work of patient breathing
and lessen patient discomfort.

During the fourth quarter of 1998, the Company received marketing
clearance from the FDA to sell its new 840* ventilator, which is
designed to become the world's leading infant-pediatric-adult critical
care ventilator.  During the second quarter of 1998, the Company
received marketing clearance from the FDA to sell its new, state-of-
the-art 740* ventilator.  The low operating and maintenance costs of
the 740* ventilator make it ideal for use in developing countries and
in subacute care facilities.  In December 1998, the Company received
FDA marketing clearance to sell the 760* ventilator.  U.S. sales
commenced in February 1999.

In its portable ventilator product line, the Company released the
Achieva* ventilator to markets outside the U.S. during 1999.  This
next generation portable ventilator adds the pressure support
ventilation modification for improved patient comfort.

The Company's medical gas business involves the filling and
distribution of nitrous oxide and other medical and specialty gases
primarily in high pressure cylinder systems.  The Company is the
largest producer of nitrous oxide in North America with 4 production
units, and distributes this along with other medical and specialty
gases through a nationwide system of 31 branches.  These products are
sold by the Company's dedicated sales force to users of medical gases
in major cities and through distributors in rural areas.

The oxygen therapy and asthma management product family covers the
entire range of oxygen therapy functions, from oxygen concentrators to
portable liquid oxygen and conservation devices.  The Company's
spirometry system measures lung capacity and performance through a
complete line of devices targeted at hospital pulmonologists and
primary care physicians.  In April 1998, the Company received 510(k)
premarket clearance from the FDA for its new spirometry system, the
Simplicity*.  This small, lightweight, handheld system is designed for
primary care physicians.  The Company also markets peak flow meters,
peak flow monitors, and other devices to help patients with asthma or
other forms of chronic obstructive pulmonary disease (COPD) to better
manage their conditions.

Diagnostic and therapeutic sleep products are used in hospital sleep
laboratories to diagnose sleep problems and in a variety of other
settings to monitor and treat sleep disorders.  In sleep therapy, the
Company received 510(k) clearance for the GoodKnight* range of
Continuous Positive Airway Pressure (CPAP) products in July 1998.  In
diagnostic products, the Company released its Windows* version of its
Sandman* polysomnography system.

HemoCue products serve the in vitro blood testing market for blood
hemoglobin and glucose analysis.  These tests are performed in
physician office laboratories, hospitals, public health facilities,
blood banks and diabetes clinics.  HemoCue has divided the U.S. market
into twelve regions, of which nine are covered by regional exclusive
distributors and three by a dedicated direct organization.
Internationally, these products are marketed primarily through
dedicated distributors.

The Company's service programs support customers during all stages of
product ownership and assist healthcare providers in merging the most
appropriate technology with the most cost-effective methods, including
CliniVision*, the market-leading handheld computing tool used in
tracking the care of respiratory impaired patients.

Mallinckrodt's customers had traditionally been physicians and
healthcare professionals in clinical settings such as critical care
units of hospitals.  With the increasing pressure to lower healthcare
costs, more patients are being treated in lower-cost areas in and
outside the hospital.  The Company's products are now purchased for
use throughout the hospital, including intermediate care and step-down
units, labor and delivery rooms, emergency rooms and general care
floors, and are marketed and sold into the alternate site care market,
including surgicenters, subacute care and skilled nursing facilities,
physicians' offices, clinics, ambulatory care settings, and the
growing home market.

The Company's products are sold in the major markets of the world
principally through a direct sales force, assisted by clinical
consultants and specialists, corporate account managers, and
distributors in the U.S. and internationally.

In January 1999, Mallinckrodt acquired Life Design Systems, Inc.
(LDS), a Dallas, Texas-based developer and manufacturer of
resuscitation bags and related accessories.  LDS produces
resuscitation bags with carbon dioxide detection capability in a range
of sizes from infant to adult.  This acquisition was accounted for
under the purchase method of accounting.

During 1999, Mallinckrodt sold Medical Gas Distribution Systems (MGDS)
and Crow River Industries (including its subsidiary company, Mobility
Products and Design).  MGDS sold the medical gas outlets, alarms and
accessories used in the movement of medical gases within hospitals.
During 1997, the Company sold Mallinckrodt Sensor Systems, Inc.  The
financial statements include the results of these businesses prior to
sale; however, the associated earnings and assets were not material to
the Respiratory segment or to Mallinckrodt Inc.

Respiratory manufacturing facilities are located in Angelholm, Sweden;
Argyle, New York; Athlone, Ireland; Carlsbad, California; El Paso,
Texas; Galway, Ireland; Indianapolis, Indiana; Irvine, California;
Johannesburg, South Africa; Juarez, Mexico; Mirandola, Italy; Nancy,
France; Plymouth, Minnesota; St. Charles, Missouri; and Tijuana,
Mexico.  Production units for the manufacture and/or purification of
nitrous oxide are located in Galena, Kansas; Maitland, Canada;
Pensacola, Florida; and Richmond, California.  The Company also
operates 31 branches which transfill and distribute medical gases.
Mallinckrodt owns the Argyle, Athlone, Carlsbad, Galway, Mirandola and
Nancy facilities.  The remainder are leased.  The Argyle, New York
facility is no longer in production and efforts are underway to divest
this facility.

For information about legal activities involving the Respiratory
segment, see the Other Litigation section of Legal Proceedings in Item
3.

Imaging
- -------

The Imaging segment includes the manufacture, sale and distribution of
products used in radiology, cardiology and nuclear medicine.

Radiology products include x-ray contrast media (ionic and nonionic),
ultrasound contrast agents, magnetic resonance imaging (MRI) agents,
and catheters for use in diagnosis and therapy.  These products are
marketed in the U.S. principally by a direct sales force.
Internationally, these products are marketed through direct sales
forces and distributors.  On August 20, 1999, the Company sold the
catheter product line and the associated manufacturing facility in
Angleton, Texas.

Cardiology products are directed toward meeting the needs of both
invasive and non-invasive cardiology in diagnosing and treating
diseases of the cardiovascular system.  The business currently offers
both ionic and nonionic contrast agents, ultrasound contrast agents,
and interventional catheters and related supplies.  These products are
sold directly to hospitals, primarily by a dedicated sales
organization within Mallinckrodt's direct sales force.  Radiology and
cardiology x-ray contrast media sales were 16 percent, 18 percent and
28 percent of Mallinckrodt's consolidated sales for 1999, 1998 and
1997, respectively.

Nuclear medicine products consist of radiopharmaceuticals used to
provide images of numerous body organs, anatomy and function, and to
diagnose and treat diseases.  Nuclear medicine products are sold in
the U.S. by a direct sales force and distributed both directly and
through a nationwide network of nuclear pharmacies.  Internationally,
nuclear medicine products are marketed through a direct sales force
and distributors.

Since its introduction in the U.S. ten years ago, Optiray*, a low
osmolar, nonionic x-ray contrast medium, has been widely accepted in
both radiology and cardiology procedures.  Optiray* began to be
introduced outside the U.S. in 1991.  To source growing Optiray*
volumes in the international market, the Company opened a new
production facility in Dublin, Ireland during 1994 for the manufacture
of Optiray* in its bulk drug form.  In addition, capacity expansion
projects at Mallinckrodt's existing plant in St. Louis, Missouri were
completed in 1994 and again in June 1997.  Mallinckrodt has also made
investments at its Dublin facility to launch a new process for the
synthesis of Ioversol, the key component of Optiray*, resulting in
lower costs and improved quality.  This process was started in
February 1998 at the Dublin, Ireland facility and is expected to be
completed at the St. Louis manufacturing site in 2000.

In June 1990, Mallinckrodt introduced Ultraject*, a patented
innovation in x-ray contrast media agent administration.  This
prefilled syringe provides a more efficient, convenient and safer
method of delivering contrast agents.  Ultraject* allows Mallinckrodt
to differentiate its x-ray contrast media offering by providing
advantages over traditional glass bottles and vials because it reduces
handling hazards and the potential for dosage error.  In January 1996,
Mallinckrodt acquired Liebel-Flarsheim Company of Cincinnati, Ohio to
enhance its position in the contrast imaging arena.  Liebel-
Flarsheim's products include x-ray contrast media power injectors for
angiography and CT, x-ray components, and specialized equipment for
diagnostic urology procedures.

In September 1996, Mallinckrodt signed a collaboration agreement with
Epix Medical Inc., formerly known as METASYN, Inc., to co-develop a
blood pool MRI agent.  Mallinckrodt has worldwide manufacturing rights
for the products developed and has selling and marketing rights to
them for all countries, except Japan.  In April 1997, Mallinckrodt
introduced GastroMARK*, an oral GI bowel marker used in MRI
procedures.  This product was licensed from Advanced Magnetics, Inc.
of Cambridge, Massachusetts and is distributed exclusively by
Mallinckrodt in the U.S., Canada, Mexico, Japan, Australia and New
Zealand.

During 1989, Mallinckrodt acquired an equity position of less than two
percent of the then outstanding common shares of Molecular Biosystems,
Inc. (MBI) of San Diego, California, and obtained exclusive marketing
rights in the Western Hemisphere for Albunex*, a new ultrasound
contrast agent.  Albunex* was approved in August 1994 with
Mallinckrodt's launch of the product occurring in the second quarter
of 1995.  On September 7, 1995, Mallinckrodt entered into a new
distribution and investment agreement for Albunex* and OPTISON*
(FS069), a new ultrasound contrast agent in development.  Under the
September 7, 1995 agreement, Mallinckrodt made an additional equity
investment of $13 million in MBI.  In addition, the agreement also
provides for Mallinckrodt to partially fund OPTISON* clinical
development and make various milestone payments.  Mallinckrodt's total
equity position in MBI pursuant to this agreement is under ten percent
of MBI's outstanding and publicly traded common stock.  In December
1996, Mallinckrodt extended the agreement with MBI to exclusively
distribute in Europe, Africa, most of Asia, Australia and New Zealand.
Albunex* received FDA approval in June 1997 for the diagnosis of
fallopian tube patency as part of infertility workup.

On December 31, 1997, OPTISON* received FDA approval.  The product was
launched in the United States on January 2, 1998.  OPTISON*, the first
of the perflourocarbon-containing ultrasound agents to reach the
market, enables physicians to enhance resolution of anatomical
structure where ultrasound alone is inadequate.  The product is
specifically indicated for use in patients with suboptimal
echocardiograms to opacify the left ventricle and to improve the
delineation of the left ventricular endocardial borders.  Ultrasound
cardiac imaging has several advantages over other imaging methods.  It
is minimally invasive, relatively inexpensive and can provide a real-
time image.

OPTISON* helps increase the effectiveness of echocardiography in
diagnosing heart disease by introducing gas-filled microspheres into
the blood.  The microspheres travel in the bloodstream to the left
ventricle of the heart, where the microspheres reflect the sound waves
generated from ultrasound equipment, enabling the development of a
clearer, more diagnostic ultrasound image.

On May 19, 1998, Mallinckrodt announced that OPTISON* had received
final marketing authorization by the European Commission for use in
patients with suspected or known cardiovascular disease.  The
authorization covers all 15 member states of the European Union.
OPTISON* is the only fluorocarbon-based agent approved for use in
Europe.

In April 1999, Mallinckrodt announced it had reached an agreement in
principle with MBI under which MBI would transfer the manufacture of
OPTISON* to the Company, and the Company would assume responsibility
for funding all cardiology, as well as radiology, clinical trials for
OPTISON* in the U.S.  The agreement in principle provided for an
effective date of March 1, 1999.  MBI and the Company are negotiating
a definitive agreement reflecting these, as well as other, terms.

The Company is a party to several legal proceedings in which the
manufacture and sale of OPTISON* is alleged to infringe upon patents
held by the plaintiffs therein.  For additional information about this
litigation, see the Other Litigation section of Legal Proceedings in
Item 3.

In 1995, Mallinckrodt signed an agreement with Medi+Physics to
distribute healthcare proprietary radiopharmaceutical products through
Medi+Physics' radiopharmacies in the U.S. and Canada.  Additionally,
in 1997, Mallinckrodt signed a 5-year co-marketing agreement with
Medi+Physics for Mallinckrodt to market Myoview*, a
radiopharmaceutical cardiac imaging agent, in the U.S.

Imaging manufacturing facilities are located in Cincinnati, Ohio;
Maryland Heights, Missouri; Mexico City, Mexico; Mulhuddart, Ireland;
Petten, the Netherlands; Pointe Claire, Canada; Raleigh, North
Carolina; and St. Louis, Missouri.  Mallinckrodt owns these
facilities.  The Company also operates 40 nuclear pharmacies of which
37 are located in population centers throughout the U.S.

Pharmaceuticals
- ---------------

The Pharmaceuticals segment's products include analgesics such as
acetaminophen (APAP) used to control pain and fever; codeine salts,
morphine and other opium-based narcotics and synthetic narcotics used
to treat pain and coughs; and peptides which are used in many new
pharmaceuticals.  Other Pharmaceuticals segment products include
laboratory chemicals used in analysis and microelectronic chemicals
used in the semiconductor industry; magnesium stearate for use as a
tableting aid in pharmaceuticals; potassium chloride for use as a
potassium supplement in pharmaceuticals and nutritionals; and other
salts, chemicals and reagents used in the production of pharmaceutical
and food products.

Most Pharmaceuticals products are sold through distributors and by a
direct sales force to the pharmaceutical industry for use in the
manufacture of dosage form drugs.  Narcotic prescription chemicals are
sold directly to pharmaceutical manufacturers, and pharmaceutical
dosage products are sold directly to drug wholesalers and chain
pharmacies, while opiate addiction products are sold primarily to
clinics.  Laboratory chemical products, which include thousands of
high-purity reagent chemicals used in research and development and
analytical laboratories, are sold primarily through distributors to
medical, industrial, educational and governmental laboratories.  A
direct sales force is used to offer microelectronic chemicals and
photoresist strippers to semi-conductor chip producers worldwide.

Mallinckrodt expanded its product offering in healthcare by acquiring
an analgesic pharmaceutical product line from King Pharmaceuticals,
Inc. in 1996.  In November 1996, Mallinckrodt acquired D.M. Graham
Laboratories, Inc. of Hobart, New York.  Graham Laboratories is a
contract manufacturer of both tablet and capsule dosage
pharmaceuticals and a licensed producer of a variety of medicinal
narcotic substances.  The Company expanded its capacity at its St.
Louis, Missouri site to manufacture pharmaceutical intermediates and
additives with the addition of an FDA registered facility in 1997.
The APAP manufacturing at the Raleigh, North Carolina facility has
been incrementally expanded over the past few years, while costs have
been reduced.  Capacity of the Derbyshire, England para-aminophenol
(PAP, a precursor of APAP) manufacturing plant has also been
significantly increased.  Mallinckrodt also upgraded its Compap*
production facility in Greenville, Illinois in 1997.  In addition, the
Company continues to work on several projects to expand and upgrade
the narcotics facility in St. Louis, Missouri to meet growing
worldwide demand.

Pharmaceuticals products are manufactured in Derbyshire, England;
Deventer, the Netherlands; Greenville, Illinois; Hayward, California;
Hobart, New York; Mexico City, Mexico; Paris, Kentucky; Phillipsburg,
New Jersey; Raleigh, North Carolina; St. Louis, Missouri; and
Torrance, California.

OTHER ACTIONS

Discontinued Operations
- -----------------------

In 1998, the Company sold or committed to sell the catalysts and
chemical additives and Aero Systems divisions.  Certain liabilities
for environmental, litigation and employee benefits remain with the
Company.  The last portion of the catalysts and chemical additives
division was sold on July 31, 1998.

On June 30, 1997, the Company sold its animal health segment for cash
plus the assumption of certain liabilities.  Certain environmental
liabilities, facility leases and liabilities for employee benefits,
including postretirement benefits, were retained by the Company.

On March 31, 1997, the Company disposed of Fries & Fries, Inc., a
wholly owned subsidiary which owned the Company's 50 percent interest
in Tastemaker, which was the flavors joint venture.

The results of these transactions and the results of operations from
these businesses have been reclassified to discontinued operations,
and prior year results have also been reclassified.  For additional
information about discontinued operations, see Management's Discussion
and Analysis of Financial Condition and Results of Operations in Item
7, and Note 2 of the Notes to Consolidated Financial Statements in
Item 8.

OTHER ACTIVITIES

Research and Development
- ------------------------

The Company performs applied research directed at development of new
products, development of new uses for existing products, and
improvement of existing products and processes.  Research and
development programs include laboratory research as well as product
development and application.  The Company's development activities are
focused on marketplace needs.  Internal research efforts in each of
its business segments are supplemented with third-party and university
technical agreements.  Research and development expenses, excluding
purchased research and development as a result of the Nellcor
acquisition in 1998, were $152.2 million, $149.0 million and $100.5
million in 1999, 1998 and 1997, respectively.

The Respiratory segment's research and development functions are
individually aligned with each of its business units.  The research
and development functions are housed most frequently near a primary
manufacturing site, which are principally located in Angelholm,
Sweden; Carlsbad, California; Hazelwood, Missouri; Irvine, California;
Mirandola, Italy; Pleasanton, California; Plymouth, Minnesota; and St.
Charles, Missouri.

Research and development activities for the Imaging segment are
performed primarily in Cincinnati, Ohio; Petten, the Netherlands; and
St. Louis, Missouri.  Research and development activities for the
Pharmaceuticals segment are carried on in Phillipsburg, New Jersey;
St. Louis, Missouri; and Torrance, California.  Technical personnel
for process support are located at each manufacturing location.

Patents, Trademarks and Licenses
- --------------------------------

Mallinckrodt owns or licenses in excess of 1,550 United States and
foreign patents that expire at various times over the next twenty
years.  Mallinckrodt owns or licenses in excess of 1,950 United States
and foreign trademarks.  The Company also currently has pending
approximately 750 United States and foreign patent applications and
over 300 United States and foreign trademark applications.  No single
patent or trademark is considered to be essential to the Company as a
whole, but in the aggregate, the patents and trademarks are of
material importance to the Company.

Government Regulation
- ---------------------

Drug and Medical Device Regulation - Most of the Company's businesses
are subject to varying degrees of governmental regulation in the
countries in which operations are conducted, and the general trend is
toward regulation of increasing stringency.  In the United States, the
drug and device industries have long been subject to regulation by
various federal, state and local agencies, primarily as to product
safety, efficacy, advertising and labeling.  The exercise of broad
regulatory powers by the FDA continues to result in increases in the
amounts of testing and documentation required for FDA clearance of new
drugs and devices and a corresponding increase in the expense of
product introduction.  Similar trends toward product and process
regulation are also evident in a number of major countries outside of
the United States, especially in the European Economic Community where
efforts are continuing to harmonize the internal regulatory systems.
In 1997, the Food and Drug Administration Modernization Act was passed
in the United States and was the culmination of a comprehensive
legislative reform effort designed to streamline regulatory procedures
within the FDA and to improve the regulation of drugs and medical
devices. The legislation was principally designed to ensure the timely
availability of safe and effective drugs and medical devices by
expediting the premarket review process for new products.

The regulatory agencies under whose purview the Company operates have
administrative powers that may subject the Company to such actions as
product recalls, seizure of products, and other civil and criminal
sanctions.  In some cases, the Company may deem it advisable to
initiate product recalls voluntarily.

Puritan-Bennett Corporation (Puritan-Bennett), which became a wholly
owned subsidiary of Mallinckrodt as a result of the acquisition of
Nellcor in August 1997, had entered into a consent decree with the FDA
in January 1994, pursuant to which Puritan-Bennett agreed to maintain
systems and procedures complying with the FDA's good manufacturing
practices regulation and medical device reporting regulation in all of
its device manufacturing facilities.  Burton A. Dole, Jr., who
currently serves as the sole director and the sole officer of Puritan-
Bennett, is a party to the consent decree.

Puritan-Bennett has experienced and will continue to experience
incremental operating costs due to ongoing regulatory compliance
requirements and quality assurance programs initiated in part as a
result of the FDA consent decree.  The amount of these incremental
costs currently cannot be completely predicted and will depend upon a
variety of factors, including future changes in statutes and
regulations governing medical device manufacturers, and the manner in
which the FDA continues to enforce and interpret the requirements of
the consent decree.

There can be no assurance that the Company will not experience
problems associated with FDA regulatory compliance, including
increased general costs of ongoing regulatory compliance and specific
costs associated with the Puritan-Bennett consent decree.  The Company
could experience a material adverse effect on business, operations,
profitability and outlook from, among other things:  (i) requirements
associated with the Puritan-Bennett consent decree; (ii) requirements
arising from continuing company-wide adherence to quality assurance
and good manufacturing practices; (iii) the results of future FDA
inspections of the operations and facilities of the Company; and (iv)
any modification, extension or adverse interpretation of the Puritan-
Bennett consent decree or any product recall, plant closure or other
FDA enforcement activity with respect to the Company.

Environmental Regulation - The Company's operations are subject to a
variety of federal, state and local environmental laws and regulations
that govern, among other things, the generation, handling, storage,
transportation, treatment and disposal of hazardous substances,
discharges to water, and air emissions from equipment and facilities.

Most of the Company's environmental-related capital expenditures are
in response to provisions of the Federal Clean Air Act; Water
Pollution Control Act; Resource Conservation and Recovery Act; and
land use, air and water protection regulations of the various
localities and states, and their foreign counterparts.  Capital
expenditures worldwide relating to air emission control, wastewater
purification, land reclamation and solid waste disposal
totaled approximately $5 million in 1999, $6 million in 1998, and $6
million in 1997.  The Company currently estimates that environmental
capital expenditures during 2000 and 2001 will be $10 million and $12
million, respectively.

The Company had previously recognized the costs associated with the
investigation and remediation of Superfund sites, the litigation of
potential environmental claims, and the investigation and remedial
activities at the Company's current and former operating sites.
Related accruals of $128.8 million at June 30, 1999 are included in
current accrued liabilities and other noncurrent liabilities and
deferred credits.  Any claims for potential recovery from any sources
have not been valued against the accrued environmental liabilities.
While ongoing litigation may eventually result in recovery of costs
expended at certain of the environmental sites, any recovery is
contingent upon a successful outcome and has not been recognized in
the Company's results of operations.

The Company has recognized the costs and associated liabilities only
for those matters that are in its view probable and estimable.  Based
upon information currently available, management believes that
existing accrued liabilities  are sufficient and that it is not
reasonably possible at this time that any additional liabilities will
result from the resolution of these matters that would have a material
adverse effect on the Company's consolidated results of operations or
financial position.

Compliance - Mallinckrodt endeavors to comply with all applicable laws
and regulations, but there can be no assurance that its compliance
efforts will always be acceptable.  Instances of non-compliance have
occurred in the past and, although they have not had a material
adverse impact on the Company, such instances could occur in the
future and possibly have a material adverse impact.  In particular,
the Company is unable to predict the extent to which it may be
adversely affected by future regulatory developments such as new or
changed laws or regulations.

In the fall of 1997, German authorities seized certain records of two
of the Company's non-U.S. subsidiaries, Mallinckrodt Medical GmbH and
Mallinckrodt Radiopharma GmbH.  These seizures were part of
investigations of certain practices at these subsidiaries that
involved payments to physicians and other German healthcare providers.
The investigations, which are ongoing, appear to focus on whether the
payments in question were for research or other services performed by
the recipients, or may have been sales incentives or discounts which
could possibly be contrary to German law.  Based on currently
available information, the Company does not believe that the German
investigations will have a material impact on the Company's
consolidated results of operations or financial position.

See the Environmental Matters section of Legal Proceedings in Item 3,
Management's Discussion and Analysis of Financial Condition and
Results of Operations in Item 7, and Note 20 of the Notes to
Consolidated Financial Statements in Item 8 for additional
information.

Employees
- ---------

Mallinckrodt had 13,098 employees at June 30, 1999, consisting of
7,531 U.S. based employees and 5,567 employees outside the U.S.

Labor Relations
- ---------------

In the U.S., the Company has ten collective bargaining agreements with
eight international unions or their affiliated locals covering 846
employees.  Four agreements covering 500 employees were negotiated
during 1999, with no work stoppages.  One agreement covering 70
employees will expire in 2000.  Nine operating locations outside the
U.S. have collective bargaining agreements and/or work counsel
agreements covering approximately 1,173 employees.  Recent wage and
benefit increases were consistent with competitive industry and
community patterns.

ITEM 2.   PROPERTIES

Information regarding the principal plant and properties of
Mallinckrodt is included in the Operations and Other Activities
sections of Business in Item 1.  The Company has distribution
locations in the U.S. in Carlsbad, California; Cincinnati, Ohio; El
Paso, Texas; Mission Viejo, California; Plymouth, Minnesota; St.
Charles, Missouri; and St. Louis, Missouri.

The Company leases space for its international operations in
Argentina, Australia, Austria, Belgium, Brazil, Canada, China,
Colombia, Finland, France, Germany, Ireland, Italy, Japan, Korea,
Malaysia, Mexico, the Netherlands, Philippines, Poland, Portugal,
Puerto Rico, Singapore, South Africa, Spain, Sweden, Switzerland and
United Kingdom.  Additionally, Mallinckrodt leases office space in St.
Louis, Missouri.

The Company believes its manufacturing and distribution facilities are
adequate, suitable and of sufficient capacity to support its current
operations.

ITEM 3.   LEGAL PROCEEDINGS

Environmental Matters
- ---------------------

The Company is actively involved in the investigation or remediation
of, or is addressing potential claims of, alleged or acknowledged
contamination at approximately 24 currently or previously owned or
operated sites and at approximately 16 off-site locations where its
waste was taken for treatment or disposal.  These actions are in
various stages of development and generally include demands for
reimbursement of previously incurred costs, or costs for future
investigation and/or for remedial actions.  In many instances, the
dollar amount of the claim is not specified.  For some sites, other
potentially responsible parties may be jointly and severally
responsible, along with the Company, to pay for any past remediation
and other related expenses.  For other sites, the Company may be
solely responsible for remediation and related costs.  The Company
anticipates that a portion of these costs will be covered by insurance
or third party indemnities.  A number of the currently pending matters
relate to historic and formerly owned operations of the Company.

Once the Company becomes aware of its potential environmental
liability at a particular site, the measurement of the related
environmental liabilities to be recorded is based on an evaluation of
currently available facts such as the extent and types of hazardous
substances at a site, the range of technologies that can be used for
remediation, evolving standards of what constitutes acceptable
remediation, presently enacted laws and regulations, engineering and
environmental specialists' estimates of the range of expected clean-up
costs that may be incurred, prior experience in remediation of
contaminated sites, and the progress to date on remediation in
process.  While the current law potentially imposes joint and several
liability upon each party at a Superfund site, the Company's
contribution to clean up costs at these sites is expected to be
limited, given the number of other companies which have also been
named as potentially responsible parties and the volumes of waste
involved.  A reasonable basis for apportionment of costs among
responsible parties is determined and the likelihood of contribution
by other parties is established.  If it is considered probable that
the Company will only have to pay its expected share of the total
clean-up, the recorded liability reflects the Company's expected
share.  In determining the probability of contribution, the Company
considers the solvency of the parties, whether responsibility is
disputed, existence of an allocation agreement, status of current
action, and experience to date regarding similar matters.  Current
information and developments are regularly assessed by the Company,
and accruals are adjusted on a quarterly basis, as required, to
provide for the expected impact of these environmental matters.

The Company has established accruals only for those matters that are
in its view probable and estimable.  Based upon information currently
available, management believes that existing accruals are sufficient
and that it is not reasonably possible at this time that any
additional liabilities will result from the resolution of these
matters that would have a material adverse effect on the Company's
consolidated results of operations or financial position.

The following is a brief discussion of certain pending environmental
proceedings which the Company believes, based on currently available
information, are most significant:

Orrington, ME - Hanlin Group, Inc. purchased a chemical manufacturing
facility located in Orrington, Maine from the Company in 1982.  In
April 1989, Hanlin filed suit in the U.S. District Court for the
District of Maine alleging that the Company had operated the facility
in violation of federal and state environmental laws.  More
specifically, Hanlin asserted that the Company had allowed the
discharge of unlawful amounts of mercury, contaminating the soil, air,
groundwater and adjoining waterways.  The parties settled these claims
in 1991.  The facility was subsequently sold to HoltraChem
Manufacturing Company, L.L.C. (HoltraChem); the settlement agreement
was assigned to HoltraChem as part of the sale.  Under the settlement
agreement, the Company agreed to pay specified costs of a study
ordered by the United States Environmental Protection Agency (EPA).  A
draft Site Investigation has been completed by the Company.
Additional investigation was required to address questions posed by
EPA and the State of Maine Department of Environmental Protection
(Maine DEP).  The Company completed the additional work to supplement
the Site Investigation and submitted the final Site Investigation plan
to the EPA and the Maine DEP on December 29, 1998.  The Company and
HoltraChem met with the Maine DEP and EPA in April 1999 to discuss the
conclusions of the Site Investigation.  The Company expects comments
on the Site Investigation plan from the agencies shortly.  Costs of
implementing remedial action at the site will be shared by the Company
and HoltraChem on a yet-to-be agreed basis.  If the parties cannot
reach agreement, the matter will be referred to binding arbitration.

On June 21, 1999, the Company and HoltraChem received a Notice of
Intent to Sue (Notice) under Section 7002(a)(1)(B) of the Resource
Conservation and Recovery Act (RCRA) sent by the Natural Resources
Defense Council, Inc. (NRDC) and the Maine People's Alliance (MPA).
NRDC and MPA allege that the Company as a former owner of the facility
contributed to mercury discharges to the environment that NRDC and MPA
assert pose a continuing risk of harm to public health and the
environment.  NRDC and MPA state that the lawsuit will request that
the Company and HoltraChem abate the hazards to the environment.  The
Notice states that suit will be filed in the United States District
Court for the District of Maine shortly after the expiration of the
ninety day notice period required by law.  The Notice invites the
Company and HoltraChem to contact representatives of NRDC and MPA to
discuss the Notice.  The Company and HoltraChem, through the RCRA
Corrective Action process and with oversight by EPA and Maine DEP, are
currently addressing issues raised in this Notice regarding
contamination attributable to the site.  The Company and HoltraChem
will evaluate this Notice and jointly determine the appropriate
response.

Auburn Hills, MI - The Company is a defendant in an action that was
filed on January 13, 1986 and is currently pending in the U.S.
District Court for the Eastern District of Michigan, styled Frank J.

1970s.  The State of Michigan (State) and the present owner of the
facility, Columbus Steel Drum Company, Inc., claim that the Company is
jointly and severally liable, along with approximately twenty other
former owners and operators of the facility, for alleged contamination
of soil and groundwater resulting from improper disposal practices.
The State seeks remedial measures at the site and reimbursement for
costs incurred to date.  The current owner seeks reimbursement for
previously incurred clean-up costs and compensation for damages to the
site.  The Company denies any violation of applicable law on its part.
The Company has filed a third-party complaint against approximately
110 parties that sent drums to the facility, seeking contribution for
damages that might be assessed against the Company.

The Company and other parties have explored settlement alternatives,
but have not reached a global settlement to date.  The Company
submitted a Remedial Action Plan (RAP) to the State of Michigan for
this site which was rejected.  Although the Company completed
additional work as requested by the State and prepared a report
describing the results of the additional work and submitted it to the
Court, the Michigan Department of Environmental Quality (MDEQ) decided
to complete additional investigation.

MDEQ hired a consultant to complete these additional studies at the
site.  MDEQ concluded that further additional investigation was
necessary before defining a final RAP for the site.  The Company does
not believe additional investigations are necessary considering the
number of investigations completed to date.  All parties are waiting
for MDEQ to define a final RAP.  The parties to the litigation have
agreed to mediate the issue of the State's past cost claims.  A
mediator has been chosen and mediation was held July 21-23, 1999.  The
mediator plans to report to the judge that negotiations would proceed
better if MDEQ has defined its remedy.  More mediation sessions are
being scheduled.  Discovery is proceeding on the other issues in the
litigation.

St. Louis, MO/CT Decommissioning - The Company processed certain ores,
columbium and tantalum, under license with the Nuclear Regulatory
Commission (NRC) from the 1960s through 1986.  Pursuant to NRC
regulations, the Company is required to complete decommissioning of
the processing areas, buildings and soil on the site where
manufacturing occurred.  The Company submitted a Phase I
Decommissioning Plan to the NRC in November 1997 and received NRC
comments in February 1999.  The Company is developing the Phase II
Decommissioning and Decontamination Plan to submit to the NRC.  This
plan was due in December 1998, but the Company received an extension
to submit the Phase II Plan in June 2000.  The Company submitted a
Financial Assurance Plan to the NRC as requested in April 1999.  The
Company is waiting for NRC comments.

St. Louis, MO/RCRA Corrective Action - The Company's St. Louis plant
has a Resource Conservation Recovery Act (RCRA) Part B permit which
requires the facility to undergo corrective action.  The Company
worked with the Missouri Department of Natural Resources (MDNR) to
complete the RCRA Facility Assessment and identified certain Solid
Waste Management Units (SWMUs) and Areas of Concern (AOCs).  The
Company received its Part B permit and appealed certain provisions.
The Company has negotiated a resolution of its appeal.  The MDNR has
conditionally approved the RCRA Facility Investigation Final Work Plan
(Work Plan) submitted by the Company, which describes additional
investigation of certain SWMUs and AOCs.  The Company has started
field work in accordance with the Work Plan and is submitting
quarterly reports to the MDNR.  Activities are continuing in
accordance with the RCRA process.

Raleigh, NC - The Company's bulk pharmaceutical facility has been
operating since the mid 1960s.  It has a Resource Conservation
Recovery Act (RCRA) Part B permit which requires the facility to
undergo corrective action.  There are several phases to the corrective
action process.  The Company has worked with federal and state
agencies to identify certain Solid Waste Management Units (SWMUs).
The Company received its permit and submitted a RCRA Facility
Investigation Work Plan (RFI Work Plan) to the North Carolina
Department of Environment, Health and Natural Resources (Agency)
proposing to investigate the SWMUs.  The Agency identified certain
technical issues concerning the RFI Work Plan and the Company
responded to these issues through revisions to the RFI Work Plan.  The
Company continues to work with the Agency to complete the RCRA
process.

Final approval of the RFI Work Plan was issued in December 1997.
Field work commenced in March 1998 and was completed in May 1998.  The
RCRA Facility Investigation Report (RFI Report) on these activities
was submitted to the Agency in February 1999.  Mallinckrodt is
awaiting approval and comment on the RFI Report.

Animal Health Business Properties - The Company sold its animal health
business in June 1997 to Schering-Plough Corporation (S-P) and
provided an environmental indemnity to S-P.  This indemnity covered
both U.S. facilities and international facilities.  The indemnity
lasts for a term of fifteen years and is limited to claims arising
from activities and uses of the property prior to closing.  The
Company is working with S-P and the Indiana Department of
Environmental Management (IDEM) to resolve certain issues regarding
the Resource Conservation and Recovery Act (RCRA) requirements at the
Terre Haute, Indiana facility.  The facility had begun the RCRA
Corrective Action process, but decided to allow the RCRA Part B permit
to expire.  Mallinckrodt and S-P have determined to proceed under the
IDEM's voluntary remediation program (VRP).  Mallinckrodt is
submitting a VRP application and is awaiting comments from IDEM.

Under the terms of the indemnity, S-P had the option to conduct
baseline environmental assessments at all of the properties
transferred.  S-P has completed initial baseline assessments and has
made certain claims against the Company under the indemnity.
Furthermore, the Company transferred several facilities to S-P as part
of the sale of the Company's animal health business in the following
South American locations:  Buenos Aires, Argentina; Cali, Colombia;
Cotia, Brazil; Itu, Brazil; and Luque, Paraguay.  During the baseline
study performed in connection with the sale, chemical constituents
were identified at these sites.  Based on the information obtained
upon completion of the baseline study, S-P determined that it needed
to further delineate the extent of any potential contamination.  S-P
provided copies of proposed investigations to the Company in late
March 1999.  The Company has hired outside consultants to assist it in
evaluating the environmental requirements of the various countries to
determine if additional investigation and/or remediation is necessary
or required.  The Company does not necessarily agree that additional
delineation and/or investigation is necessary.  The Company is
reviewing the delineation proposals made by S-P and plans to provide
comments.  S-P has not made formal claims regarding these sites.

The Company recognized the estimated incremental expense associated
with the indemnification of environmental liabilities in the loss
recorded on the sale of the business in 1997.  The Company intends to
vigorously defend its position in connection with the environmental
matters in connection with the formerly owned animal health business.

Erie, PA (Calsicat) - The Company sold its facility located in Erie,
Pennsylvania to Engelhard Corporation (Engelhard) in May 1998.  This
facility manufactures a variety of specialty catalysts.  As part of
the transaction, the Company provided an environmental indemnity to
Engelhard.  This indemnity distinguishes between on-site and off-site
liabilities.  On-site liabilities are limited to a term of five years.
The Company has an obligation to jointly manage any on-site
liabilities covered by the indemnity which require remediation.  Off-
site liabilities for activities arising from pre-closing activities
are indemnified without a time limit.  The Company and Engelhard are
working together to address an ongoing groundwater collection and soil
remediation project at the site.  This project is being managed under
the oversight of the Pennsylvania Department of Environmental
Protection (PADEP).  The Company and Engelhard have applied to
participate under the Pennsylvania voluntary remediation program for
the current groundwater collection system.  The PADEP has indicated
the voluntary remediation proposal is feasible.  The Company has
accruals to address the ongoing remediation projects and potential
environmental claims under the indemnity.

Allentown, PA (Trimet) - The Company sold its operations in Allentown,
Pennsylvania to Geo Specialty Chemicals, Inc. (Geo) in July 1998.
This facility currently manufactures formaldehyde and a limited number
of specialty chemicals.  The facility had previously been operated as
an explosives manufacturing plant.  The Company retained a portion of
the property where no manufacturing activities currently occur.  The
Company provided an environmental indemnity to Geo for certain
environmental activities which may be required by governmental
agencies and a more limited indemnity for potential environmental
claims arising from the actions of Geo.

In addition to the indemnity, the Company has retained responsibility
for completion of two ongoing remediation projects, including
demolition of certain buildings and closure of a wastewater lagoon, as
well as other environmental issues.  The Company has presented a
remediation plan to the Pennsylvania Department of Environmental
Protection (PADEP) which includes consolidation of the wastewater
lagoon sludges in one of the onsite lagoons.  The Company is in the
process of discussions with the PADEP and is coordinating these
activities with Geo.  The Company has established a reserve to address
the ongoing remediation projects, potential environmental claims under
the indemnity, and other potential environmental issues.

Springville, UT - In 1996, the Company entered into an interim
settlement agreement with Ensign-Bickford Industries, Inc. (EBI) to
share certain costs of remediating groundwater that allegedly has been
impacted by nitrates and explosive compounds emanating from EBI's
Springville, Utah explosives plant.  The plant, under a series of
owners, has been manufacturing explosives at the mouth of the Spanish
Fork Canyon in Utah since the 1940s.  The Company sold the plant and
related assets to the Trojan Corporation in 1982.  EBI acquired the
Trojan Corporation in 1986 and has operated the plant since that time.
Pursuant to a 1991 stipulation and consent order with the State of
Utah (State), EBI has conducted a feasibility study of alternatives
for remediating impacted off-site groundwater.  EBI also is conducting
a RCRA Corrective Action study under a 1995 consent order with the
State.  The Company and EBI have entered into an interim allocation
agreement with two additional parties to address funding remedial
activities at this site.

The parties have continued to meet with the Utah Department of
Environmental Quality (DEQ) to update the DEQ on the progress of the
off-site groundwater remedial activities and the progress of RCRA
Corrective Action activities at the site.  The Revised RFI Work Plan
(Plan) prepared as part of the RCRA Corrective Action process was
submitted to the DEQ in December 1998.  The DEQ commented on the Plan
and the parties provided responses to the comments.  The parties
received conditional approval of the Plan by the DEQ in June 1999.
The parties are preparing to conduct the initial analytical testing in
accordance with the Plan.  An allocation consultant hired by the
parties has been reviewing documents and is going to assist in
developing a process to negotiate a final allocation.

In October 1996, a resident with property bordering the Springville
site filed suit against EBI in the U.S. District Court for the
District of Utah (Don Henrichsen, et al v. The Ensign-Bickford
                  --------------------------------------------
Company, et al) alleging nuisance and trespass for contamination that
- --------------
allegedly migrated onto the resident's property.  On January 31, 1997,
the Company was added as a defendant.  Depositions are being completed
and expert reports have been generated.  The Plaintiffs have made
settlement overtures, but the negotiations have not progressed.  The
trial date for this case has been reset for December 1999.

Ensign-Bickford Industries, Inc. and The Ensign-Bickford Company
(jointly called, EBI) and the Company have received three additional
complaints by nearby residents alleging personal injury and property
damage from migration of contaminants from facility operations.  All
of the lawsuits have been filed in the U.S. District Court for the
District of Utah.  The lawsuits are styled as follows:  Howard Ruff
                                                        -----------
and Kay Ruff v. Ensign-Bickford Industries, Inc., et al (filed
- -------------------------------------------------------
February 26, 1999);  Charles Bates and Ellen Bates v. Ensign-Bickford
                     ------------------------------------------------
Industries, Inc., et al (filed March 9, 1999); and Rodney Petersen and
- -----------------------                            -------------------
Marilyn Petersen v. Ensign-Bickford Industries, Inc. (filed April 15,
- ----------------------------------------------------
1999).  These suits allege that the Company and EBI's actions in
operating the facility caused injury.  Answers were filed in the Ruff,
                                                                 ----
Bates, and Petersen complaints in early May 1999.  The parties are
- -----      --------
currently working on various pre-trial matters.  The Company and EBI
are jointly defending these actions.

The Company has also received another letter in connection with this
site from the children of David Nemelka and Kent Stephens who had
previously settled a lawsuit with the Company and EBI.  In this
letter, counsel for the children of these parties has made a demand
for payment to address multiple illnesses alleged to have been caused
by contaminants originating at the Springville, Utah plant site.  The
Company and EBI are currently evaluating these potential claims.  No
complaint has been filed.

The State also has advised EBI that it is investigating a natural
resource damages claim; however, the State has not indicated it plans
to pursue this claim.  Nevertheless, all parties have entered into a
Tolling Agreement with the State in connection with the potential
natural resource damages claim.

Other Litigation
- ----------------

The Company is a party to a number of other legal proceedings arising
in the ordinary course of business.  The Company does not believe
these pending legal matters will have a material adverse effect on its
financial condition or the results of the Company's operations.  The
most significant of these matters involve two products, OPTISON* and
convective warming blankets.

OPTISON* Patent Litigation - On July 31, 1997, the Company and its
licensor, Molecular BioSystems, Inc. (MBI), filed suit (the
Mallinckrodt/MBI Action) in the United States District Court for the
District of Columbia against four potential competitors - Sonus
Pharmaceuticals, Inc. (Sonus), Nycomed Imaging AS (Nycomed), ImaRx
Pharmaceutical Corp. (ImaRx) and its marketing partner DuPont Merck,
and Bracco International BV (Bracco) - seeking declarations that
certain of their ultrasound contrast agent patents are invalid.  The
complaint alleges that each of the defendant's patents are invalid on
a variety of independent grounds under United States patent laws.  In
addition to requesting that all of the patents in question be declared
invalid, the complaint requests a declaration that contrary to the
defendants' contentions, MBI and the Company do not infringe the
defendants' patents, and asks that the defendants be enjoined from
proceeding against MBI and the Company for infringement until the
status of the defendants' patents has been determined by the court or
the U.S. Patent and Trademark Office (PTO).  The complaint alleges
that each defendant has claimed or is likely to claim that its patent
or patents cover OPTISON* and will attempt to prevent its
commercialization.

Each of the defendants, except Nycomed, filed a motion to dismiss the
complaint on jurisdictional grounds.  In January 1998, the court
dismissed the complaint against (a) ImaRx (and its marketing partner,
DuPont Merck) and Bracco for lack of jurisdiction, and (b) Sonus for
improper venue.  The court's ruling did not purport to rule on the
merits of the Company and MBI's claims.  The Company and MBI elected
not to appeal the court's decision.  Accordingly, only the action
against Nycomed is proceeding in the District Court for the District
of Columbia.  Discovery in the Mallinckrodt/MBI Action against Nycomed
has been stayed until the court rules on a motion filed by the Company
and MBI for summary judgment on the grounds of invalidity of Nycomed's
patent.  The motion has been fully briefed and the parties are
awaiting the court's ruling.

On April 21, 1998, Nycomed filed an action in the District Court of
The Hague, the Netherlands against various Mallinckrodt European
entities and MBI, alleging that OPTISON* infringed or will infringe
its European patent EP 0576521.  Nycomed is seeking an injunction
against future sales and damages.  The patent that is the subject of
this action is the counterpart of Nycomed's United States patent that
is the subject matter of the Mallinckrodt/MBI Action.  A hearing was
scheduled for October 1998.

On October 13, 1998, Mallinckrodt Medical B.V., through counsel,
appeared in court in response to the legal action filed by Nycomed in
the District Court of The Hague.  The other named defendants,
Mallinckrodt Medical GmbH, Mallinckrodt Medizintechnik GmbH,
Mallinckrodt Chemical GmbH, Mallinckrodt Medical Holdings GmbH,
Mallinckrodt Chemical Holdings GmbH, and MBI were not as yet served
and did not appear.  For Nycomed to proceed with the action, it must
formally serve the six unserved defendants outside the Netherlands
under The Hague Convention.

Following the dismissal of Sonus as a defendant in the
Mallinckrodt/MBI Action, Sonus activated a patent infringement lawsuit
(the Sonus Action) that it had filed on August 4, 1997 against the
Company and MBI in the United States District Court for the Western
District of Washington.  Although the complaint was filed in August
1997, Sonus had agreed not to proceed with its action until the
jurisdictional motions were decided in the Mallinckrodt/MBI Action.
Sonus's complaint alleges that the manufacture and sale of OPTISON* by
the Company and MBI infringe two patents owned by Sonus.  The Company
and MBI have filed a counterclaim seeking a declaration of invalidity
and non-infringement with respect to the Sonus patents.

The Sonus Action was stayed until reexamination proceedings in the PTO
were concluded.  These proceedings have concluded with the PTO
confirming patentability of some of the claims in the two patents
under reexamination.

The court has lifted the stay and pretrial discovery has resumed.
Trial is scheduled for early in calendar year 2000.  The Company will
continue to challenge the Sonus patents in this litigation.

On May 3, 1999, ImaRx and DuPont Pharmaceuticals (DuPont) filed suit
against MBI and the Company in the United States District Court for
the District of Delaware.  The suit alleges that the manufacture and
sale of OPTISON* by the Company and MBI infringe two patents owned by
ImaRx and licensed to DuPont.  As noted above, the Company and MBI had
previously filed an action in July 1997 in the United States District
Court for the District of Columbia to declare these patents invalid or
not infringed, but that action was dismissed on jurisdictional
grounds.  Since that time, the patents have undergone reexamination in
the PTO with the PTO recently confirming patentability of the claims
of the patents.  The Company and MBI will defend this suit on the
grounds of invalidity and non-infringement with respect to the ImaRx
patents.

Augustine Medical, Inc. - On October 6, 1994, Augustine Medical, Inc.
(Augustine) commenced patent infringement litigation against
Mallinckrodt Group Inc. and Mallinckrodt Medical, Inc. (the Company)
in the United States District Court for the District of Minnesota.
The original complaint was amended to include allegations of patent
infringement regarding U.S. Patent Nos. 4,572,188 (the '188 patent);
5,300,102 (the '102 patent); 5,324,320 (the '320 patent); and
4,405,371 (the '371 patent).  Specifically, Augustine alleged that the
Company's sale of all five (5) models of its convective warming
blankets infringes certain claims of one or more of the aforementioned
patents.  Augustine sought to have the Company permanently enjoined
from further acts of alleged infringement and an award of damages
adequate to compensate for the Company's alleged infringement,
together with attorneys' fees.  Augustine included a claim of willful
infringement and requested enhanced damages based thereon.

The Company filed a motion for summary judgment of non-infringement of
all of the asserted patents and the magistrate judge issued a report
and recommendations dated March 18, 1996 indicating that there is no
literal infringement of the '188 patent, but that factual questions
existed with respect to infringement of the '102 patent, the '320
patent, and the '371 patent (the Remaining Patents) and as to whether
the '188 patent is infringed under the doctrine of equivalents.  The
Company also filed a motion for summary judgment of invalidity of
certain claims of the '371 patent.  The court granted the Company's
motion for summary judgment and found claims 1, 3, 4 and 8 of
Augustine's '371 patent to be invalid.

On July 18, 1997, the magistrate judge issued a report and
recommendation indicating that in addition to there being no literal
infringement of the '188 patent, there is no infringement under the
doctrine of equivalents.  This was confirmed by the court and the '188
patent was eliminated from the case.

The liability phase of the case was tried to a jury in August 1997 and
the verdict was that the Company's blankets infringe the Remaining
Patents under the doctrine of equivalents, but do not literally
infringe the patents.  There was also a finding of no willful
infringement.  On September 22, 1997, the jury awarded damages in the
amount of $16.8 million.  The Company appealed the jury verdicts of
liability and damages to the Court of Appeals for the Federal Circuit
(a special court for patent appeals).  With the advice of outside
counsel, the Company believed there was insufficient evidence of
equivalents presented and consequently for this and other reasons the
verdicts were in error.

On June 8, 1999, the Court of Appeals for the Federal Circuit
overturned the District Court's ruling, holding that the Company's
blankets do not infringe Augustine's patents.  On June 21, 1999,
Augustine filed a motion for reconsideration by the Court of Appeals
for the Federal Circuit.  On August 8, 1999, this motion was denied
and on August 13, 1999, the decision of the Court of Appeals for the
Federal Circuit was issued as a mandate to the District Court.  The
District Court in Minneapolis has ordered a hearing on September 16,
1999 to settle any remaining issues including Mallinckrodt's petition
for costs and attorneys' fees.

On February 24, 1998, Augustine filed an action in the District Court
of The Hague, the Netherlands against Mallinckrodt Inc., various
Mallinckrodt European entities and Mallinckrodt distributors
(collectively Mallinckrodt) alleging that Mallinckrodt Warm Touch*
blankets infringe its European patent EP 0311336.  Augustine sought an
injunction against future sales and damages.  This European patent is
a counterpart of Augustine's United States patent which was the
subject matter of above-described litigation between the parties in
the United States District Court in the District of Minnesota.  Trial
of this action was held in December 1998.

In February 1999, the court held that Mallinckrodt's blankets do not
infringe Augustine's European patent.  Augustine has appealed the
court's ruling.  Mallinckrodt's response to the appeal is due in
September, 1999.

(1)  On August 28, 1997, the Company acquired Nellcor Puritan Bennett
     Incorporated (Nellcor) through an agreement to purchase for cash
     all of the outstanding shares of common stock of Nellcor for
     $28.50 per share.  The aggregate purchase price of the Nellcor
     acquisition was approximately $1.9 billion, and $308.3 million of
     the purchase price was allocated to purchased research and
     development.  This intangible asset, which had no tax benefit,
     was charged to results of operations during 1998.  Of the total
     charge of $308.3 million, $2.0 million related to the Aero
     Systems division which was sold and reclassified to discontinued
     operations in 1998.

     The sale of Nellcor inventories, which were stepped up to fair
     value in connection with allocation of purchase price, decreased
     earnings by $75.4 million, $46.7 million net of taxes for 1998.
     After-tax charges to the Respiratory segment, which are included
     in earnings (loss) from continuing operations, were $46.1
     million.  After-tax charges to discontinued operations related to
     the Aero Systems division were $.6 million.

     Costs of exiting certain activities related to Mallinckrodt
     operations plus integration costs of the combined Mallinckrodt
     and Nellcor operations were $68.6 million, $46.4 million net of
     taxes.  See the Exit Activities and Restructuring Charges section
     of Note 2 of the Notes to Consolidated Financial Statements for
     additional disclosure.

(2)  See Note 2 of Notes to Consolidated Financial Statements for
     information on discontinued operations in 1999, 1998 and 1997.
     Results for 1996 and 1995 represent earnings from the catalysts
     and chemical additives division, animal health segment, Fries &
     Fries, Inc., and the feed ingredients business, partially offset
     by environmental and related litigation charges.

(3)  In April 1998, the American Institute of Certified Public
     Accountants (AICPA) issued SOP 98-5, "Reporting on the Costs of
     Start-Up Activities" (SOP 98-5), which requires that costs
     related to start-up activities be expensed as incurred.  Prior to
     1998, the Company capitalized its preoperating costs incurred in
     connection with opening a new facility.  The Company elected to
     early adopt the provisions of SOP 98-5 in its financial
     statements for 1998.  The effect of adoption of SOP 98-5 was to
     record a charge of $8.4 million, net of taxes, for the cumulative
     effect of an accounting change to expense costs that had
     previously been capitalized prior to July 1, 1997.

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

Mallinckrodt Inc. and its subsidiaries, collectively, are called the
"Company" or "Mallinckrodt."  All references to years are to fiscal
years ended June 30 unless otherwise stated.  The 1998 consolidated
financial statements were restated for a reduction in purchased
research and development and a corresponding increase in goodwill,
which resulted in an increase in amortization expense.  Certain
amounts in prior years were reclassified to conform to the current
year presentation.  All earnings per share amounts are calculated on a
diluted basis unless otherwise stated.

OVERVIEW

1999 vs. 1998
- -------------

In 1999, Mallinckrodt had earnings from continuing operations of
$172.9 million, or $2.40 per share.  The Company incurred a loss from
continuing operations of $268.4 million, or $3.69 per share, for 1998.
The 1998 results of operations included nonrecurring acquisition and
integration charges related to the acquisition of Nellcor Puritan
Bennett Incorporated (Nellcor) in August 1997 which totaled $398.8
million net of taxes, or $5.47 per share.  Excluding these charges,
earnings from continuing operations would have been $130.4 million, or
$1.77 per share.  The 1999 earnings from continuing operations and per
share results represent improvements of 33 percent and 36 percent,
respectively, when compared to 1998 results after excluding the
nonrecurring charges.  This year over year improvement is primarily
attributable to operating earnings improvement in the Respiratory and
Pharmaceuticals segments of the Company's operations while
profitability of the Imaging segment declined.

Net earnings for 1999 were $196.2 million, or $2.72 per share as
compared to a net loss of $204.4 million, or $2.81 per share during
the prior year.  Net earnings for 1999 included an after-tax gain of
$23.3 million on the sale of the remaining operation of the catalysts
and chemical additives division which was reclassified to discontinued
operations in 1998.  The net loss in 1998 included an after-tax gain
of $80.3 million associated with the completed sales and results of
operations of the catalysts and chemical additives and Aero Systems
divisions.  During the third quarter of 1998, the Company recorded an
after-tax charge of $7.9 million related to settlement costs from the
sale of the animal health business in the prior year.  The net loss
for 1998 also included an after-tax charge of $8.4 million for the
cumulative effect of an accounting change for the early adoption of a
new standard of accounting related to previously capitalized start-up
costs.

Net sales for 1999 increased 9 percent to $2.58 billion compared with
$2.37 billion in 1998.  Sales to customers outside the U.S. were $838
million or 32 percent of total 1999 sales.  The year to year sales
comparison benefited from the fact that 1998 sales only included sales
of Nellcor after the acquisition which occurred on August 28, 1997.

The acquisition of Nellcor was accounted for under the purchase method
of accounting and, accordingly, the results of operations of Nellcor
have been included in the Company's consolidated financial statements
since September 1, 1997.  The purchase price of the acquisition was
allocated to the assets acquired and liabilities assumed based upon
generally accepted accounting principles and estimated fair values at
the date of acquisition.

As a result of the Nellcor acquisition, purchased research and
development valued at $308.3 million was charged to operations during
the first quarter of 1998.  The purchased research and development
represents the value of numerous new medical devices and other
products/technologies underway in all major product lines of Nellcor
that were in various stages of development and had not reached
technological feasibility at the date of acquisition.  The value
represents the projected net cash flows based upon management's
estimates of future revenues and expected profitability of each
product/technology.  The projected net cash flows were discounted at a
rate which accounts for the time value of money as well as the risks
of realization of the cash flows.  The discounted cash flows were then
reduced to reflect only the accomplishments made by Nellcor through
the acquisition date toward the products' ultimate completion.

The largest components of purchased research and development were in
the pulse oximetry, including perinatal, and the hospital ventilator
businesses which represent approximately 63 percent and 15 percent,
respectively, of purchased research and development.

The pulse oximetry projects underway at the date of acquisition
related to development of new monitors and disposable sensors.  The
most significant project involves a new family of products that
provide enhanced capabilities and ease of use.  This project
anticipated sales revenue to begin in 2000.  With many of the
products/features of this new family of products still in development,
the market release dates for all the items in this line of next
generation products has not been finalized.  The other major project
within oximetry is the development of a fetal oximeter, a new monitor
to directly measure fetal oxygenation during labor and delivery.  This
perinatal product is intended to provide reassurance to obstetricians
when a baby is adequately oxygenated in the presence of a non-
reassuring fetal heart rate (FHR).  In this common situation, a
cesarean section is often performed due to concern for possible fetal
distress - as suggested by the FHR pattern.  Unfortunately, since a
non-reassuring FHR is an indirect indicator of fetal hypoxia with poor
specificity, many of these cesarean sections are retrospectively seen
to be unnecessary.  By providing a direct measure of oxygenation, the
fetal oximeter may help prevent unnecessary cesarean sections for
suspected fetal distress.  Although Mallinckrodt and several partners
are already marketing this technology in more than 20 countries, it is
pending final PMA submission in the United States.  Sales to date are
below original projections because the Company expected a large
percentage of global revenue to be generated in the United States due
to its relatively high birth rate utilizing cesarean section.

The most significant projects in development in the hospital
ventilator business at the date of acquisition were the Models 840*
and 740*/760* ventilators.  These hospital ventilators were expected
to be commercially available in the U.S. within two years of the
acquisition date.  All three models received U.S. Food and Drug
Administration (FDA) market clearance by December 1998.  Actual
revenues of these projects have experienced shortfalls when compared
to revenue estimates as of the acquisition date.  These shortfalls are
primarily attributable to delays in receiving regulatory clearance to
market and problems with production ramp up activities which often
occur in the early stages of manufacturing a new product.  These
factors are no longer concerns and, although sales were less than
expected in 1998, the ramp up in 1999 was consistent with our
expectations.  Revenue shortfalls experienced to date are not
indicative of any expected inability of these products to meet
customer needs or their long-term revenue expectations.

Although market release dates for the most significant in-process
projects and acquired technologies discussed above have experienced
delays, the projections of total revenues to be generated and
estimated costs to complete that were developed at acquisition date
were appropriate.  Based upon results to date, the major risks
associated with completion and commercialization of these products are
to transform concepts into designs that meet customer requirements,
gain regulatory approval and market clearance in key markets, and ramp
up the manufacturing process once regulatory approval is obtained.
Actual revenue shortfalls, which have occurred to date in these
businesses when compared with projections developed at the date of
acquisition, are not expected to materially reduce the expected long-
term revenues of these products, but only the timing of the receipt of
these revenues.  Material negative variations from the projected
results, should they occur, will reduce the expected rate of return on
the investment to acquire Nellcor and negatively impact the Company's
consolidated results of operations and financial position.

Immediately after the acquisition of Nellcor was consummated,
management of the combined Company formulated an integration plan to
combine Mallinckrodt and Nellcor into one company.  Since both
companies (Mallinckrodt and Nellcor) had global healthcare operations,
senior management, through transition teams, assessed which activities
should be consolidated.  Management finalized and approved a Nellcor
integration plan during 1998.  Accordingly, the Company recorded
additional purchase liabilities during 1998 of $50.1 million, $30.8
million net of related tax benefit, which were included in the
acquisition cost allocation and related goodwill.  The principal
actions of the plan included the involuntary severance of
approximately 450 Nellcor employees as a result of work force
reduction primarily in U.S. administrative areas at a cost of $37.2
million, relocation of Nellcor employees at a cost of $3.8 million,
and the elimination of contractual obligations of Nellcor which had no
future economic benefit at a cost of $9.1 million.  The actual number
of employees terminated was 425.  Approximately $45.4 million of cash
expenditures were incurred through June 30, 1999 and liabilities of
$1.6 million related to the Nellcor integration plan remained in
accrued liabilities at June 30, 1999.  In June 1999, the estimated
liability was reduced by $3.1 million, $1.9 million net of related tax
benefit, with a corresponding $1.9 million reduction of goodwill
primarily as a result of reduced severance costs.  The remaining cash
expenditures will occur in 2000 and, although none are expected,
further reductions in the estimated liability for these integration
activities will be offset against the related goodwill.

During 1998, the Company recorded a pretax charge to selling,
administrative and general expenses of $19.1 million associated with
exiting certain activities related to Mallinckrodt operations.  The
charge included severance costs of $17.1 million related to the
involuntary severance of approximately 130 Mallinckrodt employees as a
result of work force reduction primarily in the Europe administration
function and U.S. sales force, and facility exit costs of $2.0 million.
The actual number of employees terminated was 115.  Approximately
$14.5 million of cash expenditures have been incurred through June 30,
1999.  In June 1999, the associated accrual was reduced by $.7 million
and credited to selling, administrative and general expenses.  The
remaining $3.9 million cash expenditures will occur in 2000.
Restructuring actions are to be complete in 2000 and no further
adjustments to the reserve are anticipated.

1998 vs. 1997
- -------------

During the past two years, Mallinckrodt completed the largest
acquisition in its history and divested certain businesses to improve
the strategic position and focus of the Company.

On August 28, 1997, the Company acquired Nellcor through an agreement
to purchase for cash all of the outstanding shares of common stock of
Nellcor for $28.50 per share.  The aggregate purchase price of the
Nellcor acquisition was approximately $1.9 billion.  Nellcor is the
worldwide market leader in providing products that monitor, diagnose
and treat respiratory impaired patients.  The product lines include
pulse oximetry monitors and sensors, critical care and portable
ventilators, home oxygen therapy products, sleep apnea diagnostic and
therapy products, and medical gas products and distribution systems.

The acquisition was accounted for under the purchase method of
accounting and, accordingly, the results of operations of Nellcor have
been included in the Company's consolidated financial statements since
September 1, 1997.

The purchase price of the acquisition was allocated to the assets
acquired and liabilities assumed based upon generally accepted
accounting principles and estimated fair values at the date of
acquisition.  Identifiable intangible assets were purchased research
and development, technology, trademarks and trade names, and the
assembled work force.  The purchased research and development of
$308.3 million was charged to expense in 1998.  Technology, also
referred to as core or base technology and which represents that
portion of the existing technology that provides a basis for future
generation products as well as existing products, was recorded at
$374.2 million and is being amortized on a straight-line basis over 15
years.  The remaining identifiable intangible assets of $152.9 million
are being amortized on a straight-line basis over 10 to 25 years
(weighted-average life of 24 years).  Goodwill, which represents the
excess of the purchase price over the fair value of the net assets
acquired, was $814.2 million and is being amortized on a straight-line
basis over 30 years.  The amortization of identifiable intangible
assets and goodwill directly associated with the Nellcor acquisition
was $48.9 million for 1998.  Since the results of Nellcor have only
been included in the Company's consolidated results since September
1997, the amortization for 1998 represented ten months of activity.
The Company also recorded a deferred tax liability of $211.0 million,
representing the tax effect of timing differences recorded as part of
the acquisition.

The Company's most significant divestitures were the animal health
business and flavors joint venture in 1997 and the sale of the
catalysts and chemical additives and Aero Systems divisions in 1998
and early in 1999.  The Company now operates predominantly in the
healthcare industry and is comprised of three business segments -
Respiratory, Imaging and Pharmaceuticals.

The Company incurred a loss from continuing operations of $268.4
million, or $3.69 per share, for 1998 due to nonrecurring acquisition
and integration charges related to the acquisition of Nellcor which
totaled $449.3 million, $398.8 million net of taxes or $5.47 per
share.  The nonrecurring noncash acquisition charges were purchased
research and development and inventory stepped up to fair value.

The purchased research and development valued at $308.3 million was
charged to operations during the first quarter of 1998.  The
components of purchased research and development by business were
pulse oximetry including perinatal - $194 million; hospital
ventilators - $45 million; oxygen therapy - $20 million; and sleep,
alternate care and other - $49 million.  Of this amount, $306.3
million related to the Respiratory segment and $2.0 million related to
the Aero Systems division, which was sold and reclassified to
discontinued operations in the fourth quarter of 1998.

The purchased research and development represents the value of
numerous new medical devices and other products/technologies in all
major product lines that were in various stages of development and had
not reached technological feasibility at the transaction date.  No
alternative future uses were identified prior to reaching
technological feasibility because of the uniqueness of the projects.
Additionally, no identifiable alternate markets were established for
projects that were in early stages of development.

The most significant acquired projects, based upon discounted cash
flows, that were in-process at the date of acquisition were in pulse
oximetry and hospital ventilation.  Pulse oximetry, which includes
monitors, sensors, OEM and licensing, and related service for all
types of patients and environments including perinatal, generated
approximately 63 percent of purchased research and development value.
Pulse oximetry products provide the continuous measurement of arterial
oxygen saturation, pulse rate and pulse strength in a variety of
settings and for a spectrum of patients.  The most significant of the
pulse oximetry projects underway at the date of acquisition included a
new family of monitors and sensors that incorporate new light emitting
diode and detector component designs with enhanced motion tolerance
capability, packaging and integration of data storage features to
allow advanced performance, cost reduction, production automation,
size reduction and reduced power requirements.  In the area of fetal
pulse oximetry, the major products in development are expected to help
lower the risks involved in childbirth by reducing unnecessary
cesarean section deliveries.  The Company believes fetal pulse
oximetry can help clinicians make better informed decisions regarding
the status of a fetus during labor and delivery by providing
information that helps them determine if the fetus is adequately
oxygenated when the heart rate pattern is non-reassuring.  These
projects are expected to be complete and the related products
commercially available in the U.S. within three years of the
acquisition date with an expected cost to complete of approximately
$20 million.

The hospital ventilation projects generated approximately 15 percent
of the purchased research and development value.  Hospital ventilators
provide ventilation to patients requiring respiratory support.  The
most significant projects that were underway at the date of
acquisition were Models 840* and 740*/760* which were to provide
continuous respiratory support for a wide range of pediatric to adult
patients for a wide variety of clinical conditions.  The Model 840* is
a dual microprocessor controlled critical care ventilator for infant,
pediatric and adult patients who require either invasive or
noninvasive ventilation with features that include a graphic user
interface for viewing patient data and setting parameters and alarm
values.  The Model 740*/760* is a low cost critical care ventilator
with a new engine capable of operating with low power consumption.
The Model 760*, built on the 740* platform, has pressure and volume
control features.  The products were expected to be commercially
available within two years of the acquisition date with an estimated
cost to complete of approximately $8 million.  All three models
received FDA market clearance by December 1998.

Oxygen therapy represents the third largest business category of
projects in terms of purchased research and development value.  Oxygen
therapy covers the entire range of functions from oxygen concentrators
to portable liquid oxygen, to high pressure oxygen cylinder systems
and conservation devices.  The most significant projects underway at
the date of acquisition were liquid oxygen systems using cryogenics to
reduce the frequency of deliveries, and new oxygen concentrators with
features which include reduced noise levels, fewer parts, lighter
weight and lower cost to manufacture.  These projects are expected to
be complete and the related products commercially available within
four years of the acquisition date with an expected cost to complete
of approximately $12 million.

The major risks associated with timely completion and
commercialization of these products are to transform concepts into
designs that meet customer requirements, gain regulatory approval and
market clearance in the key markets, and ramp up the manufacturing
process once regulatory approval is obtained.

While the assembled work force was valued using the cost approach, the
Company took the following steps to determine the purchased research
and development, developed technology, and trademarks and trade name
values.  The projected net cash flows from each product line and new
product in development were determined based upon management's
estimates of future revenues and expected profitability related to the
product portfolio.  These cash flows were then discounted to their
present values.  The discount rate includes a rate of return which
accounts for the time value of money as well as the investment risk
factors to appropriately reflect the risks of realization of the cash
flows.  The projected net cash flows were discounted to present value
utilizing discount rates of 15 percent, 16 percent and 20 percent for
developed technology, purchased research and development, and
trademarks and trade names, respectively.  For the purchased research
and development, the discounted cash flows from in-process projects
were then reduced to reflect only the accomplishments made by Nellcor
toward the products' ultimate completion through the acquisition date.

The projected net cash flows were developed in the following manner.
Revenue assumptions were based upon the growth rates for markets
served and the estimated life of each product's technology.
Significant aggregate revenue growth as projected by the Company's
strategic marketing units for developed and in-process products
assumed increasing demand for medical devices, and the Company's
ability to maintain a significant share of the market.  The projected
revenues associated with in-process technology increase to $937
million in 2004 and then decline over subsequent years, while revenue
assumptions for the developed products remain relatively flat in 1999
as compared to 1998 and then begin to decline gradually in subsequent
periods.  The trademark and trade name cash flows were based upon the
revenues of both developed and in-process products and a 2 percent
royalty rate.  Costs of goods sold, expressed as a percent of revenue,
were expected to decrease from current projections of 48 percent to 43
percent over time.  Gross margins, as they relate inversely to costs
of goods sold as a percentage of revenue, were assumed to increase, in
the aggregate, over time due mainly to improving efficiency in the
manufacturing processes and more profitable products having a greater
impact on total sales.  Selling, general and administration expenses,
excluding depreciation and amortization, expressed as a percent of
revenues were estimated at 24 percent for all periods.  Maintenance
research and development expense, which includes routine changes,
additions and modifications undertaken after a product is introduced
to the market, was established at 2 percent of revenue for both
developed and in-process technologies for all periods.  An after-tax
cash flow was then calculated by deducting income tax expense and
contributory asset charges from operating income.

Results through 1998 were consistent with the underlying projections
and assumptions of revenues to be generated, estimated costs to
complete and completion dates for the in-process projects and acquired
technologies.  Material negative variations from the projected results
would impact the Company's expected return on its investment in
Nellcor, its future results of operations and financial position.  In
1998, the Company received market approval and launched the Model 740*
and Model 840* ventilators.  These products, although delayed
approximately three months from expected launch date, have been well
accepted in the market place.

The sale of Nellcor inventories, which as part of the purchase price
allocation were stepped up to fair value, decreased earnings by $75.4
million, $46.7 million net of taxes.  The pretax charges to the
Respiratory segment and Aero Systems division, which was sold and
reclassified to discontinued operations in the fourth quarter of 1998,
were $74.4 million and $1.0 million, respectively.

With the acquisition complete, the Company began integrating the
operations of Nellcor with those of Mallinckrodt's other businesses.
Management finalized and approved a Nellcor integration plan during
1998.  Accordingly, the Company recorded additional purchase
liabilities of $50.1 million, $30.8 million net of related tax
benefit, which were included in the acquisition cost allocation and
related goodwill.  In addition, the Company recorded pretax charges to
operations during 1998 of $68.6 million, $46.4 million net of taxes,
associated with exiting certain activities related to the operation of
Mallinckrodt prior to the acquisition of Nellcor and other integration
costs of the combined Company.

Excluding the nonrecurring acquisition and integration charges in
1998, the Company had earnings from continuing operations of $130.4
million, or $1.77 per share.  Included in these results are after-tax
charges of $8.5 million, or 12 cents per share, primarily to increase
reserves for Nellcor trade receivables and inventory.  Earnings from
continuing operations for 1997 were $175.2 million, or $2.33 per
share.

The year to year decline in earnings from continuing operations, after
excluding nonrecurring acquisition and integration charges, is
primarily attributable to selling price reductions and the dilutive
effect of the Nellcor acquisition-related intangible and goodwill
amortization expense and interest expense.  The aggregate purchase
price of Nellcor of approximately $1.9 billion was paid through use of
available cash and cash equivalents and additional borrowings.  The
resulting higher interest expense exceeded the operating earnings of
the Nellcor operations during 1998.  The competitive demand for
selling price reductions from healthcare customer buying groups
continued throughout 1998.  This trend, which is expected to continue,
had its most significant impact on the Company's Imaging segment where
the potential for generic competitive products and available
manufacturing capacity continue to cause lower prices.

The Company recorded a net loss for 1998 of $204.4 million, or $2.81
per share as compared to net earnings of $190.1 million, or $2.53 per
share during the prior year.  During 1998, the Company sold, or
committed to sell, its catalysts and chemical additives and Aero
Systems divisions.  The completed actions resulted in an after-tax
gain in 1998 of $68.9 million.  The sale of the remainder of the
catalysts and chemical additives division on July 31, 1998 resulted in
a gain to be included in the 1999 results of discontinued operations.
The gains on the completed sales and the results of operations for
these divisions have been reclassified to discontinued operations in
the fourth quarter of 1998 and, accordingly, prior year results have
also been reclassified.  Earnings, net of taxes, of these discontinued
operations were $11.4 million and $10.5 million for 1998 and 1997,
respectively.  During the third quarter of 1998, the Company recorded
an after-tax charge of $7.9 million related to settlement costs from
the sale of the animal health business in the prior year.  The net
loss for 1998 also included an after-tax noncash charge of $8.4
million, or 11 cents per share, for the early adoption of a new
standard of accounting related to previously capitalized start-up
costs.  The cumulative effect of the accounting change was recorded in
the fourth quarter, but was effective as of July 1, 1997.  Operating
earnings would have been reduced by $2.3 million after taxes or 3
cents per share had the Company not adopted the accounting change.

Net earnings for 1997 included a $270.6 million after-tax gain from
discontinued operations resulting from the March 31, 1997 disposition
of Fries & Fries, Inc., a wholly owned subsidiary which owned the
Company's 50 percent interest in Tastemaker, the flavors joint
venture, and a $269.4 million after-tax loss from discontinued
operations resulting from the sale of the animal health segment on
June 30, 1997.

Net sales for 1998 increased 39 percent to $2.37 billion compared with
$1.70 billion in 1997.  Sales to customers outside the U.S. were $792
million or 33 percent of total 1998 sales.  Excluding sales of
Nellcor, which was acquired at the end of August 1997, sales were
$1.69 billion which is equal to the prior year.  Excluding the
acquisition and integration charges discussed above, operating
earnings were $286.3 million, a decrease of $11.2 million or 4 percent
from the prior year.  Excluding the results of Nellcor and the
acquisition and integration charges discussed above, operating
earnings were $248.1 million or 17 percent below the 1997 results of
$297.5 million.  The decline in operating earnings was driven by
competitive price pressure in the Imaging segment and critical care
business.

1999 vs. 1998
- -------------

Operating earnings for 1999 were $363 million, which is a 17 percent
improvement over the $309 million in 1998 excluding acquisition and
integration charges associated with the acquisition of Nellcor which
were discussed previously, and corporate expense.

The Respiratory segment, of which Nellcor is a part, had sales for
1999 of $1,144 million, or 15 percent greater than the sales recorded
for 1998.  The segment's sales increase of $153 million was
attributable to volume growth of 17 percent, of which 10 percent was
due to the inclusion of ten months of Nellcor revenue in 1998.  The 7
percent volume growth in the comparable September through June periods
included $97 million or 12 percent overall growth of pulse oximetry,
ventilation, service, anesthesiology and respiratory disposables,
blood analysis and medical gases.  Volume declines of $27 million
included $11 million associated with divested business and $16 million
in the oxygen therapy, sleep and portable ventilation lines of
business.  The volume declines in the on-going businesses were
primarily due to delayed new product introductions and competitive
pressures associated with customer third-party reimbursement on
existing products in these businesses.  Operating earnings of this
segment for 1999 were $140 million, or 37 percent greater than the
$102 million reported for the prior year.  The year to year
improvement was primarily attributable to the two additional months of
sales and higher sales volumes in product lines generating the highest
margins.

The Imaging segment's sales in 1999 were $776 million, or 2 percent
above the sales for the prior year.  The sales increase was
attributable to a $30 million increase in sales of nuclear medicine
products.  All major product lines contributed to the year over year
volume increase of 4 percent, which was offset by price erosion in x-
ray contrast media.  Although price declines of 5 percent in the x-ray
contrast media portion of the business in 1999 were less significant
when compared to those experienced in prior years, declines will
continue in future periods thus reducing profitability further.
Operating earnings for 1999 were $120 million, which is 4 percent
lower than in the prior year primarily as a result of selling price
erosion in x-ray contrast media.

The Pharmaceuticals segment's sales for 1999 were $661 million, or 7
percent above the revenues generated last year.  The sales increase of
$45 million was primarily attributable to volume increases in
narcotics and drug chemicals of $52 million, which was an increase of
17 percent.  Sales volumes of acetaminophen and laboratory and
microelectronic chemicals declined 5 percent and 6 percent,
respectively.  The decline in acetaminophen sales was primarily due to
a late flu season in the U.S., while the decline in laboratory and
microelectronic chemicals was primarily attributable to the weakness
in the microchip industry.  Price generated a 2 percent increase in
sales for the segment when compared to the prior year.  New
competitors are expected in narcotics manufacturing during 2000 which
may negatively impact selling prices.  Operating earnings for 1999
were $103 million, or 24 percent above prior year primarily as a
result of increased sales of higher margin products.

1998 vs. 1997
- -------------

The Company's 1998 operating earnings excluding charges related to
acquisition and integration activities and corporate expense were $309
million, which represented a 4 percent decline when compared to the
prior year.  Excluding the results of Nellcor, acquired in August
1997, the acquisition and integration charges, and corporate expense,
operating earnings would have been $271 million or 16 percent below
1997.  This earnings decline was attributable to lower selling prices
which were only partially offset by higher volume.  The competitive
pressures and the demand for price discounts from customer buying
groups adversely affected earnings, and this trend is expected to
continue.  In response to this market trend, the Company entered into
a multi-year agreement in 1996 with Premier Purchasing Partners, L.P.
(Premier), the largest healthcare purchasing group in the United
States.  Effective July 1, 1997, Premier named Mallinckrodt a
corporate partner and, accordingly, Premier's 1,800 hospital and
healthcare facilities are provided incentives to use Mallinckrodt
products.

The Respiratory segment, which includes Nellcor and the critical care
business, reported operating earnings of $102 million, an increase of
34 percent over the results for 1997.  Excluding Nellcor, operating
earnings were $64 million, a 16 percent decrease from prior year.  The
year to year earnings decline was attributable to a sales decline of
$16 million resulting from the negative impact of exchange rate
movements caused by the strengthening of the U.S. dollar versus major
European currencies and the Japanese yen, $8 million due to price
declines and another $6 million attributable to the divestiture of a
product line in September 1996.  These sales shortfalls were only
partially offset by volume increases of $14 million and $11 million in
disposable respiratory and anesthesiology product lines, respectively.

The Imaging segment had operating earnings of $124 million in 1998,
which was a decline of $40 million or 24 percent from the prior year.
The decline in profitability was directly attributable to a sales
decline of $42 million - from $802 million in 1997 to $760 million in
1998.  All product lines had volume increases which represented an
increase of $85 million over the prior year.  In spite of these
increases, erosion of selling price accounted for a $102 million sales
decline.  The remainder of the shortfall in 1998 when compared to 1997
was attributable to the impact of exchange rate movements caused by
the strengthening of the U.S. dollar versus major European currencies
and the Japanese yen.  X-ray contrast media, the segment's most
significant product line, had sales volume increases of $44 million,
but price erosion reduced sales by $85 million.  The pricing pressures
were most significant in the U.S. where the Company and its x-ray
contrast media competitors utilize price concessions to maintain or
grow their shares in a market dominated by large customer buying
groups.  The agreement with Premier aligns the Company with the
largest healthcare purchasing group in the U.S., representing
approximately 30 percent of all x-ray contrast media purchased.  The
Premier agreement is believed to be the largest contract ever written
for these products.  In spite of cost reductions in x-ray contrast
media manufacturing and lower operating expenses, the price erosion
reduced profitability, and is expected to reduce profitability in
future periods but at a lower rate of decline than was experienced in
1998 and 1997.

The Pharmaceuticals segment, which includes bulk and dosage
pharmaceuticals, peptides, and process, laboratory and microelectronic
chemicals, had 1998 operating earnings of $83 million, which was $1
million or 1 percent above results for the prior year.  In spite of
higher sales, product mix, lower than expected sales of high margin
dosage and other specialty products, and the related impact on plant
efficiencies negatively impacted operating earnings.  Sales were $616
million, which represented an increase of $41 million or 7 percent
above 1997 results.  The sales increase was partially generated by a
$19 million increase in dosage analgesic volume, of which
approximately $7 million was attributable to the full year impact from
an acquisition in November 1996.  The remainder of the sales increase
was attributable to volume growth in all other product lines.  The
impact of buying groups is less evident in the Pharmaceuticals
segment.  Overall, this segment was able to maintain pricing at prior
year levels.

CORPORATE MATTERS

Corporate expense was up $2 million or 8 percent in 1999 over 1998,
excluding 1998 nonrecurring integration charges.  The current year
increase is primarily attributable to costs associated with the
development and implementation of a cost management and productivity
improvement program.  Corporate expense in 1998, excluding
nonrecurring integration charges, was $23 million or 7 percent below
the 1997 level.

Interest and other nonoperating income, net was only $1.5 million in
1999, compared with $14.8 million and $22.0 million in 1998 and 1997,
respectively.  In 1998 and 1997, the Company generated interest income
on cash proceeds from 1997 divestiture activities invested in interest
bearing securities.  These cash equivalents were utilized to acquire
Nellcor at the end of August 1997.

Interest expense in 1999 was $85.0 million, which is $16.8 million
below the $101.8 million for the prior year.  The reduction in
interest expense was attributable to lower outstanding debt, as
divestiture proceeds generated in 1999 and 1998 were partially used to
reduce short-term borrowing, and lower short-term borrowing costs.
The 1998 interest expense was $53.8 million higher than was recorded
in 1997, primarily a result of borrowings to purchase for cash all the
outstanding shares of common stock of Nellcor.

The Company's effective tax rate was 32.0 percent in 1999.  Excluding
the one-time noncash write-off of purchased research and development,
which related to the Nellcor acquisition and which had no tax benefit,
the Company's effective tax rate in 1998 was 32.7 percent.  The 1997
effective tax rate was 35.5 percent.

FINANCIAL CONDITION

The Company's financial resources are expected to continue to be
adequate to support existing businesses.  Since June 30, 1998, cash
and cash equivalents decreased $22.8 million.  Operations provided
$193.6 million of cash, while capital spending totaled $116.9 million.
The Company received $75.4 million in proceeds from asset disposals
and $89.8 million in proceeds from redemption and sale of investments.
The Company's current ratio at June 30, 1999 was 1.0:1.  Debt as a
percentage of invested capital was 51.5 percent at the end of 1999.

At June 30, 1999, the Company had a $1.0 billion private placement
commercial paper program.  The program is backed by a $1.0 billion
revolving credit facility expiring September 12, 2002.  The revolving
credit facility was reduced from $1.6 billion in September 1998.
There were no borrowings outstanding under the revolving credit
facility as of June 30, 1999.  Commercial paper borrowings under this
program were $160.3 million as of June 30, 1999.  Non-U.S. lines of
credit totaling $139.5 million were also available, and borrowings
under these lines amounted to $17.7 million at June 30, 1999.  The
non-U.S. lines are cancelable at any time.

In May 1999, a $500 million shelf debt registration was declared
effective and at June 30, 1999 the entire amount remained available.

The Company has $200 million aggregate principal amount of 5.99
percent notes, which mature in 2010, and are redeemable at the
election of the holder, in whole but not in part, at 100 percent of
the principal amount on January 14, 2000.  These notes have been
reclassified to short-term.

The Company's Board of Directors previously authorized repurchase of
47 million shares of common stock and additional repurchases not to
exceed cash outlays of $250 million.  Share repurchases under these
authorizations have totaled 39.8 million shares, including 3.0 million
shares during 1999.

Estimated capital spending for the year ending June 30, 2000 is
approximately $160 million.

Year 2000 Readiness Disclosure
- ------------------------------

The Year 2000 issue is the result of date-sensitive devices, systems
and computer programs that were deployed using two digits rather than
four to define the applicable year.  Any such technologies may
recognize a year containing "00" as the year 1900 rather than the year
2000.  If left unaddressed, this could result in a system failure or
miscalculations, under certain circumstances, causing disruptions of
operations including, among other things, a temporary inability to
process transactions or engage in similar normal business activities.

Mallinckrodt has developed and is implementing a comprehensive program
to address the Year 2000 issue.  The program has four major focus
areas:  information technology systems, non-information technology
systems, products, and key supplier and business partners.  Overall,
the Company has completed its assessment in the above described areas,
and has substantially completed required modifications, replacements
or conversions.

Information technology systems are hardware and software which support
business applications.  Year 2000 compliance for these systems
included modification and testing of existing systems and replacement
of certain systems with new technologies.  We believe required
modifications, replacements and testing of critical systems are
approximately 99 percent completed.

Non-information technology systems (embedded systems) are used in
research and development, manufacturing processes and facility
management systems.  We believe all remediation decisions, and
modifications and replacements deemed appropriate for critical items,
are completed.

Compliance status and applicable remediation steps for currently and
previously marketed products have been communicated via the Internet
using a dedicated web page.  Modifications necessary to achieve
remediation for such products are available to customers in accordance
with the above communicated remediation steps.

The Company is also assessing the readiness of its key suppliers and
business partners to be Year 2000 compliant.  Information requests
have been distributed and responses received from virtually all those
queried.  To augment these evaluations, more detailed reviews of
certain key suppliers and business partners are being conducted.  This
part of the program is approximately 98 percent complete and, to date,
no matters have been identified from the replies received that would
appear to materially affect the operations of the Company's
businesses.

To further recognize potential adverse impact, the Company is
developing operating contingency plans to address unanticipated
interruptions that could occur in processes, systems and devices that
have been assessed, remediated and considered Year 2000 ready by
Mallinckrodt and its key suppliers and business partners.  Such
operating contingency plans are approximately 90 percent finished,
with completion expected by September 30, 1999.

The program to address Year 2000 has been underway since February
1997.  Both internal and external resources are being used to assess
and modify or replace non-compliant technologies, and to appropriately
test Year 2000 modifications and replacements.  The program is being
funded through operating cash flows.  The pretax costs incurred for
this effort were approximately $10 million, $7 million and $1 million
in 1999, 1998 and 1997, respectively.  In July through December 1999,
the Company anticipates an additional $2 million in pretax costs for
program management and to complete monitoring and evaluations of key
suppliers and business partners, program verification and contingency
planning.

The cost of the program and the date on which the Company believes it
will complete Year 2000 modifications are based on management's best
estimates.  If the modifications and conversions are not made or are
not completed timely and operating contingency plans do not work as
anticipated, the result could be an interruption, or a failure, of
certain normal business activities or operations.  Such failures could
materially impact and adversely affect the Company's results of
operation, liquidity and financial condition.  In addition,
disruptions in the economy generally resulting from Year 2000 issues
could materially and adversely affect the Company.

The Company presently believes it has an effective plan to anticipate
and resolve any potential Year 2000 issues in a timely manner, and
that, with the completion of the program as scheduled, the possibility
of a material interruption of normal operations should be reduced.

European Monetary Union (EMU)
- -----------------------------

The euro was introduced on January 1, 1999, at which time the eleven
participating EMU member countries established fixed conversion rates
between their existing currencies (legacy currencies) and the euro.
The legacy currencies will continue to be valid as legal tender
through June 30, 2002; thereafter, the legacy currencies will be
canceled and euro bills and coins will be used for cash transactions
in the participating countries.

The Company's European sales offices and various manufacturing and
distribution facilities affected by the euro conversion have
established plans to address the systems issues raised by the euro
currency conversion.  The Company's legacy currency systems, which
have multi-currency functionality, were modified at minimal expense to
enable them to process euro transactions effective January 1, 1999.
The Company believes the cost of converting the information technology
and other systems to the euro will not be significant, and that such
conversions will be completed on a timely basis prior to any
anticipated negative impact on the Company's operations.  The Company
is cognizant of the potential business implications of converting to a
common currency; however, it is unable to determine, at this time, the
ultimate financial impact of the conversion on its operations, if any,
given that the impact will be dependent upon the competitive
situations which exist in the various regional markets in which the
Company participates and the potential actions which may or may not be
taken by the Company's competitors and suppliers.

Mallinckrodt believes converting to the euro will have no material
impact on the Company's currency exchange cost and/or risk exposure,
continuity of contracts or taxation.

ENVIRONMENTAL MATTERS

The Company is subject to various investigations, claims and legal
proceedings covering a wide range of matters that arise in the
ordinary course of its business activities.  In addition, the Company
is in varying stages of active investigation or remediation of, or is
addressing potential claims of, alleged or acknowledged contamination
at approximately 24 currently or previously owned or operated sites
and at approximately 16 off-site locations where its waste was taken
for treatment or disposal.

Once the Company becomes aware of its potential environmental
liability at a particular site, the measurement of the related
environmental liabilities to be recorded is based on an evaluation of
currently available facts such as the extent and types of hazardous
substances at a site, the range of technologies that can be used for
remediation, evolving standards of what constitutes acceptable
remediation, presently enacted laws and regulations, engineers and
environmental specialists' estimates of the range of expected clean-up
costs that may be incurred, prior experience in remediation of
contaminated sites, and the progress to date on remediation in
process.  While the current law potentially imposes joint and several
liability upon each party at a Superfund site, the Company's
contribution to clean up these sites is expected to be limited, given
the number of other companies which have also been named as
potentially responsible parties and the volumes of waste involved.  A
reasonable basis for apportionment of costs among responsible parties
is determined and the likelihood of contribution by other parties is
established.  If it is considered probable that the Company will only
have to pay its expected share of the total clean-up, the recorded
liability reflects the Company's expected share.  In determining the
probability of contribution, the Company considers the solvency of the
parties, whether responsibility is disputed, existence of an
allocation agreement, status of current action, and experience to date
regarding similar matters.  Current information and developments are
regularly assessed by the Company, and accruals are adjusted on a
quarterly basis, as required, to provide for the expected impact of
these environmental matters.

Most of the Company's environmental-related capital expenditures are
in response to provisions of the Federal Clean Air Act; Water
Pollution Control Act; Resource Conservation and Recovery Act; and
land use, air and water protection regulations of the various
localities and states, and their foreign counterparts.  Capital
expenditures worldwide relating to air emission control, wastewater
purification, land reclamation and solid waste disposal totaled
approximately $5 million in 1999, $6 million in 1998, and $6 million
in 1997.  The Company currently estimates that environmental capital
expenditures during 2000 and 2001 will be $10 million and $12 million,
respectively.

The Company had previously recognized the costs associated with the
investigation and remediation of Superfund sites, the litigation of
potential environmental claims, and the investigation and remedial
activities at the Company's current and former operating sites.
Related accruals of $128.8 million at June 30, 1999 are included in
current accrued liabilities and other noncurrent liabilities and
deferred credits.  Any claims for potential recovery from any sources
have not been valued against the accrued environmental liabilities.
While ongoing litigation may eventually result in recovery of costs
expended at certain of the environmental sites, any recovery is
contingent upon a successful outcome and has not been recognized in
the Company's results of operations.

The Company has recognized the costs and associated liabilities only
for those matters that are in its view probable and estimable.  Based
upon information currently available, management believes that
existing accrued liabilities are sufficient and that it is not
reasonably possible at this time that any additional liabilities will
result from the resolution of these matters that would have a material
adverse effect on the Company's consolidated results of operations or
financial position.

RISK MANAGEMENT STRATEGIES

The Company operates globally, with manufacturing and distribution
facilities in various countries throughout the world, and is subject
to certain opportunities and risks, including foreign currency
fluctuations and government actions.  Various operational initiatives
are employed to help manage business risks.  In the ordinary course of
business, Mallinckrodt purchases materials and sells finished products
denominated in approximately 25 different currencies.  The Company is
primarily exposed to changes in exchange rates of the German deutsche
mark and other Euro currencies, the Japanese yen and the Australian
dollar.  Overall, the Company is a net beneficiary when the U.S.
dollar weakens and is adversely affected by a stronger U.S. dollar
relative to the major currencies identified.

Operations in each country are monitored so that the Company can
quickly respond to changing economic and political environments as
well as changes in foreign currency exchange rates and interest rates.
The Company enters into forward foreign exchange contracts and
currency swaps to minimize the exposure on intercompany financing
transactions.  To minimize the impact of anticipated foreign currency
exposures which arise from probable purchases of raw materials or
other inventory, collection of accounts receivable, settlement of
accounts payable, and periodic debt service by international
subsidiaries which occur in the ordinary course of business, the
Company hedges a portion of its non-U.S. dollar denominated exposures
by purchasing currency options which generally have terms of two years
or less, and which have little or no intrinsic value at time of
purchase.  The Company uses the options with an objective of limiting
negative foreign exchange rate effects on overall performance for both
budget and prior year comparisons over a rolling 18- to 24-month
horizon.  The Company seeks to have effective coverage levels over
such 18- to 24-month horizon of 50 to 80 percent of currency exposures
that subject the Company to risk.  The hedges are designed to satisfy
the requirements for deferral accounting treatment at inception.
Gains and losses in the hedges are expected to be systematically
monetized with concurrent reinvestment to replace monetized hedges and
maintain overall hedging coverage targets.  The net impact of foreign
exchange activities on earnings was immaterial for 1999, 1998 and
1997, including conversion of certain currencies into functional
currencies and the costs of hedging certain transactions and balance
sheet exposures.  The foreign currency translation loss included in
accumulated other comprehensive loss in shareholders' equity, and
resulting from the translation of the financial statements of most of
the Company's international affiliates into U.S. dollars, increased by
$28.7 million in 1999 due to the strengthening of the U.S. dollar
against the functional currency of many of the Company's international
affiliates.

The Company's interest income and expense are most sensitive to
changes in the general level of U.S. interest rates.  In this regard,
changes in U.S. interest rates affect the interest earned on the
Company's cash equivalents and short-term investments as well as
interest paid on its short-term debt.  To manage the interest rate
characteristics of its outstanding debt to a more desirable fixed or
variable rate basis or to limit the Company's exposure to rising
interest rates, the Company periodically enters into interest rate
swaps and option contracts.

The Company does not consider the present general rate of inflation to
have a significant impact on the businesses in which it operates.

While future economic events cannot be predicted, the Company believes
its current operations and future expansion plans will not result in a
significantly different risk profile.

ITEM 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company has determined that its market risk exposures, which arise
primarily from exposures to fluctuations in interest rates and foreign
currency rates, are not material to its future earnings, fair value
and cash flows.

REPORT OF INDEPENDENT AUDITORS

To the Shareholders and Board of Directors of Mallinckrodt Inc.

We have audited the accompanying consolidated balance sheets of
Mallinckrodt Inc. as of June 30, 1999 and 1998, and the related
consolidated statements of operations, changes in shareholders'
equity, and cash flows for each of the three years in the period ended
June 30, 1999, appearing on pages 35 through 56.  These consolidated
financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the consolidated
financial position of Mallinckrodt Inc. at June 30, 1999 and 1998, and
the consolidated results of its operations and its cash flows for each
of the three years in the period ended June 30, 1999, in conformity
with generally accepted accounting principles.

As discussed in Note 1 to the consolidated financial statements, in
the year ended June 30, 1998, the Company adopted Statement of
Position 98-5, "Reporting on the Costs of Start-Up Activities."

RESPONSIBILITY FOR FINANCIAL REPORTING

The consolidated financial statements included in this report are the
responsibility of management.  The statements have been prepared in
conformity with generally accepted accounting principles and include
amounts based on our best estimates and judgments.  Financial
information appearing elsewhere in this report is consistent with that
in the financial statements.

Management is also responsible for maintaining systems of internal
accounting control with the objectives of providing reasonable
assurance at reasonable cost that the Company's assets are safeguarded
against material loss from unauthorized use or disposition and that
transactions are properly authorized and recorded to permit reliance
on the Company's financial data and records.  In addition, the Company
maintains a program for communicating corporate policy throughout the
organization and, as a further safeguard, an internal audit staff
monitors compliance with policies and systems of internal accounting
control.

Mallinckrodt's consolidated financial statements have been audited by
Ernst & Young LLP.  To express their opinion as to the fairness of the
statements in conformity with generally accepted accounting
principles, the independent auditors review and evaluate
Mallinckrodt's accounting controls and conduct such tests and other
procedures as they deem necessary.  The Audit Committee of the Board
of Directors regularly meets with the independent auditors, without
management present, to review financial reporting matters, and audit
and control functions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Mallinckrodt Inc. and its subsidiaries, collectively, are called the
"Company" or "Mallinckrodt."  All references to years are to fiscal
years ended June 30 unless otherwise stated.  The 1998 consolidated
financial statements were restated for a reduction in purchased
research and development and a corresponding increase in goodwill,
which resulted in an increase in amortization expense.  Disclosures
relate to continuing operations, unless otherwise stated.  Certain
amounts in prior years were reclassified to conform to the current
year presentation.  All earnings per share amounts are calculated on a
diluted basis unless otherwise stated.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

Financial statements of all majority owned subsidiaries are
consolidated.  Investments in 20 to 50 percent owned affiliates are
reported on the equity method.  Intercompany transactions are
eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities, disclosure of contingent assets and liabilities at the
date of the financial statements, and the revenues and expenses during
the reporting period, as well as amounts included in the Notes.  While
the Company uses its best estimates and judgments, actual results
could differ from these estimates.

Foreign Currency Translation

The financial statements of most of the Company's international
affiliates are translated into U.S. dollars using current exchange
rates for balance sheets and weighted-average rates for income
statements.  Unrealized translation adjustments are included in
accumulated other comprehensive loss in shareholders' equity in the
Consolidated Balance Sheets.

The financial statements of international affiliates that operate in
hyperinflationary economies in certain Latin American countries are
translated at current and historical exchange rates, as appropriate.
Unrealized translation adjustments are included in operating results
for these affiliates.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of certificates of
deposit, time deposits and other short-term securities with maturities
of three months or less from the date of purchase.

Inventories

Inventories are valued at the lower of cost or market.  Cost for
inventories is determined on either an average or first-in, first-out
basis.

Investments

The Company's investments in marketable equity securities are
classified as "available-for-sale" and are carried at fair market
value, with the unrealized gains and losses included, net of income
taxes, in accumulated other comprehensive loss in shareholders' equity
in the Consolidated Balance Sheets.  Interest, dividends and realized
gains and losses on the sale of such securities are included in
interest and other nonoperating income, net.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost.  Depreciation is
based upon estimated useful lives of 10 to 45 years for buildings and
3 to 15 years for machinery and equipment, using principally the
straight-line method.

The Company recognizes impairment losses for long-lived assets to be
held and used whenever events or changes in circumstances indicate
that the carrying amount of the assets exceeds the sum of the expected
undiscounted future cash flows associated with such assets.  The
measurement of the impairment losses to be recognized is based on the
difference between the fair values and the carrying amounts of the
assets.  Long-lived assets held for sale are reported at the lower of
carrying amount or fair value less cost to sell.

Intangible Assets

The cost of product line or business acquisitions accounted for using
the purchase method is allocated first to identifiable assets and
liabilities based on estimated fair values.  The excess of cost over
identifiable assets and liabilities is recorded as goodwill.

Goodwill is amortized on a straight-line basis over 10 to 40 years
(weighted-average life of 29 years).  Technology is amortized on a
straight-line basis over 15 to 25 years (weighted-average life of 16
years).  Other intangible assets, consisting primarily of trademarks,
trade names, and manufacturing and distribution agreements, are
amortized primarily on a straight-line basis over 3 to 40 years
(weighted-average life of 20 years).

The carrying amounts of intangible assets and goodwill are routinely
reviewed to determine if facts and circumstances suggest that they may
be impaired.  If this review indicates that the carrying amounts of
intangible assets and goodwill will not be recoverable, as determined
based on the estimated undiscounted cash flows of the entity acquired
over the remaining amortization period, the carrying amounts of the
intangible assets and goodwill are reduced by the estimated shortfall
of cash flows.  In addition, intangible assets and goodwill associated
with assets acquired in a purchase business combination are included
in impairment evaluations when events and circumstances exist that
indicate the carrying amount of those assets may not be recoverable.

Derivative Financial Instruments

The Company uses interest rate swaps and options to manage the
interest rate characteristics of its outstanding debt to a more
desirable fixed or variable rate basis or to limit the Company's
exposure to rising interest rates; forward foreign exchange agreements
and currency swaps to minimize the exposure on intercompany financing
transactions; and foreign exchange option contracts to minimize the
impact of anticipated foreign currency exposures which arise from
probable purchases of raw materials or other inventory, collection of
accounts receivable, settlement of accounts payable, and periodic debt
service by international subsidiaries which occur in the ordinary
course of business.

Interest rate differentials to be paid or received as a result of an
interest rate swap are accrued and recognized as an adjustment of
interest expense related to the designated debt.  Interest rate option
premiums paid are amortized to interest expense ratably during the
life of the agreement.  Amounts related to interest rate swaps and the
intrinsic value of terminated option agreements are deferred and
amortized as an adjustment to interest expense over the original
period of interest exposure, provided the designated liability
continues to exist or is probable of occurring.

The Company uses forward foreign exchange contracts and currency swaps
to hedge intercompany financial activity denominated in currencies
other than the functional currency of the entity involved.  Forward
foreign exchange contracts and currency swaps are carried off-balance-
sheet with unrealized and realized gains and losses included in the
measurement and recording of the hedged transactions.

The Company hedges a portion of its anticipated foreign currency
exchange exposure using certain derivative financial instruments,
primarily purchased options to sell foreign currencies with little or
no intrinsic value at time of purchase.  These contracts are
designated and effective as hedges of the Company's consolidated
foreign currency exchange exposures.  Gains on option contracts that
are designated as hedges (including open, matured and terminated
contracts), and which have nominal intrinsic value at the time of
purchase, are deferred and recognized in earnings at the time the
underlying hedged exposure occurs.  Premiums on purchased options are
recorded as assets and amortized over the lives of the options.
Realized and unrealized gains on options relating to exposures that
are no longer probable of occurring are included as foreign exchange
gains in other operating income, net in the accompanying Consolidated
Statements of Operations.

Revenue Recognition and Product Warranty

The Company recognizes revenue at the time of product shipment and
provides currently for estimated discounts, rebates, product returns,
and the cost to repair or replace products under the warranty
provisions in effect at the time of sale.

Stock-Based Compensation

The Company accounts for its stock-based compensation plans using the
intrinsic value method prescribed by Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees." Financial
Accounting Standards Board (FASB) Statement No. 123, "Accounting for
Stock-Based Compensation" (SFAS 123), requires that companies electing
to continue using the intrinsic value method make pro forma
disclosures of net earnings and earnings per share as if the fair-
value-based method of accounting had been applied.  See Note 17 for
the fair value disclosures required under SFAS 123.

Advertising Costs

All advertising costs are expensed as incurred and included in
selling, administrative and general expenses.  Advertising expense was
$20.0 million, $20.1 million and $20.5 million in 1999, 1998 and 1997,
respectively.

Recent Accounting Pronouncements

Adopted

In April 1998, the American Institute of Certified Public Accountants
(AICPA) issued SOP 98-5, "Reporting on the Costs of Start-Up
Activities" (SOP 98-5), which requires that costs related to start-up
activities be expensed as incurred.  Prior to 1998, the Company
capitalized its pre-operating costs incurred in connection with
opening a new facility.  In the fourth quarter of 1998, the Company
elected to early adopt the provisions of SOP 98-5 in its consolidated
financial statements for the year ended June 30, 1998.  The effect of
adoption of SOP 98-5 was to record a charge of $8.4 million, net of
taxes, for the cumulative effect of an accounting change to expense
costs that had previously been capitalized prior to July 1, 1997.

In February 1998, the FASB issued Statement No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits" (SFAS
132), which revises the disclosure requirements for employers'
pensions and other retiree benefits.  Mallinckrodt has adopted SFAS
132 in 1999 and the required disclosures are presented in Note 14.

In June 1997, the FASB issued Statement No. 131, "Disclosures About
Segments of an Enterprise and Related Information" (SFAS 131).  This
statement establishes standards for the reporting of information about
operating segments in annual and interim financial statements and
requires restatement of prior year information.  SFAS 131 defines
operating segments as components of an enterprise for which separate
financial information is available that is evaluated regularly by the
chief operating decision maker(s) in deciding how to allocate
resources and in assessing performance.  SFAS 131 also requires
disclosures about products and services, geographic areas and major
customers.  The adoption of SFAS 131 in 1999 did not affect results of
operations or financial position but did affect the disclosure of
segment information, as presented in Note 18.

In June 1997, the FASB issued Statement No. 130, "Reporting
Comprehensive Income" (SFAS 130).  This statement establishes new
standards for the reporting and display of comprehensive income and
its components.  The adoption of SFAS 130 in the first quarter of 1999
did not affect the Company's results of operation or financial
position but did affect the presentation of information.  Mallinckrodt
has disclosed the required information in the Consolidated Statements
of Changes in Shareholders' Equity and in Note 15.

Yet-to-be-Adopted

FASB Statement No. 133, "Accounting for Derivative Instruments and
Hedging Activities" (SFAS 133), is required to be adopted in years
beginning after June 15, 2000.  This statement will require the
Company to recognize all derivatives on the balance sheet at fair
value.  Derivatives that are not hedges must be adjusted to fair value
through income.  If the derivative is a hedge, depending on the nature
of the hedge, changes in the fair value of the derivative will either
be offset against the change in fair value of the hedged assets,
liabilities or firm commitments through earnings or recognized in
other comprehensive income until the hedged item is recognized in
earnings. Hedge ineffectiveness, the amount by which the change in the
value of a hedge does not exactly offset the change in the value of
the hedged item, will be immediately recognized in earnings.  The
Company continues to evaluate alternative hedging strategies and their
corresponding effects under SFAS 133 on the future consolidated
results of operations and financial position.

NOTE 2 - CHANGES IN BUSINESS

Acquisitions

NELLCOR PURITAN BENNETT INCORPORATED

On August 28, 1997, the Company acquired Nellcor Puritan Bennett
Incorporated (Nellcor) through an agreement to purchase for cash all
of the outstanding shares of common stock of Nellcor for $28.50 per
share.  The aggregate purchase price of the Nellcor acquisition was
approximately $1.9 billion.  The Company completed the acquisition
using cash and cash equivalents and borrowed approximately $1.1
billion under a $2.0 billion credit facility established in July 1997,
and amended and restated in September 1997.

The acquisition was accounted for under the purchase method of
accounting and, accordingly, the results of operations of Nellcor have
been included in the Company's consolidated financial statements since
September 1, 1997.  The purchase price of the acquisition was
allocated to the assets acquired and liabilities assumed based upon
generally accepted accounting principles and estimated fair values at
the date of acquisition.  The excess of the purchase price over the
fair value of the net identifiable assets, totaling $814.2 million,
was allocated to goodwill and is being amortized on a straight-line
basis over 30 years.  The Company also recorded a deferred tax
liability of $211.0 million, representing the tax effect of timing
differences recorded as part of the acquisition.

Approximately $835.4 million of the purchase price was allocated to
identifiable intangible assets including purchased research and
development of $308.3 million, technology of $374.2 million, and
trademarks and trade names and assembled work force of $152.9 million.
(See Note 1 for amortization periods and methods for intangible
assets.)

The purchased research and development represents the value of
numerous new medical devices and other  products/technologies underway
in all major product lines of Nellcor that were in various stages of
development and had not reached technological feasibility at the
transaction date.  No alternative future uses were identified prior to
reaching technological feasibility because of the uniqueness of the
projects.  Additionally, no identifiable alternate markets were
established for projects that were in early stages of development.
The major risks associated with timely completion and
commercialization are to transform concepts into designs that meet
customer requirements, gain regulatory approval and market clearance
in the key markets, and ramp up the manufacturing process once
regulatory approval is obtained.  Management is primarily responsible
for estimating the fair value of purchased research and development.
To determine the value of the purchased research and development, the
expected future net cash flows of the in-process technology were
determined based on forecasts of future results as of the acquisition
date for each project that management believed at the acquisition date
were likely to occur.  The projected net cash flows were discounted at
a rate which accounts for the time value of money as well as the risks
of realization of the cash flows.  The discounted cash flows were then
reduced to reflect only the accomplishment made by Nellcor through the
acquisition date toward the products' ultimate completion.  The
assumptions used in determining the value of purchased research and
development represented management's good faith best estimates of the
in-process products' likely performance as of the acquisition date.
The purchased research and development intangible asset, which had no
tax benefit, was charged to results of operations during the first
quarter of 1998.  Of the total charge of $308.3 million, $2.0 million
related to the Aero Systems division, which was sold and reclassified
to discontinued operations in the fourth quarter of 1998.

The sale of Nellcor inventories, which were stepped up to fair value
in connection with allocation of purchase price, decreased earnings by
$75.4 million, $46.7 million net of taxes for 1998.  Pretax charges to
the Respiratory segment and Aero Systems division, which was sold and
reclassified to discontinued operations in the fourth quarter of 1998,
were $74.4 million and $1.0 million, respectively.

OTHER

In November 1996, the Company acquired D.M. Graham Laboratories, Inc.,
a contract manufacturer of dosage pharmaceuticals and a licensed
producer of a variety of medicinal narcotics, for $22 million of the
Company's common stock.  This acquisition was accounted for under the
purchase method of accounting, and results of operations were included
in the consolidated financial statements from the acquisition date.
Results of operations for the periods prior to acquisition were not
material to Mallinckrodt.

Discontinued Operations

The Company sold certain chemical additive product lines in the second
quarter of 1998, and recorded a gain on sale, net of taxes, of $8.7
million.  In the fourth quarter of 1998, the Company sold its catalyst
business and Aero Systems division.  The catalyst sale resulted in a
gain, net of taxes, of $60.2 million.  No gain or loss was recognized
on the sale of the Aero Systems division, and there were no earnings
from operations.  In June 1998, the Company committed to the sale of
the remaining chemical additives business of the catalysts and
chemical additives division, and closing of the sale occurred on July
31, 1998.  This transaction resulted in a gain, net of taxes, of $23.3
million and earnings from operations were zero for the one month of
operations in 1999.  Certain liabilities for environmental, litigation
and employee benefits remained with the Company, and reserves were
established to address these liabilities as deemed appropriate.
Earnings, net of taxes, from the catalysts and chemical additives
division for 1999, 1998 and 1997 were zero, $11.4 million and $10.5
million, respectively.

On March 31, 1997, the Company disposed of Fries & Fries, Inc., a
wholly owned subsidiary which owned the Company's 50 percent interest
in Tastemaker, the flavors joint venture.  The Company recorded a gain
on divestiture, net of taxes, of $270.6 million.  Earnings, net of
taxes, from the divested business for 1997 were zero.  The disposition
included the assumption of $510 million of debt of Fries & Fries, Inc.
by the buyer.  Interest expense related to the assumed debt of $22.4
million for 1997 is included in the above Fries & Fries, Inc. net
after-tax results of operations reclassified to discontinued
operations.

On June 30, 1997, the Company sold the animal health segment for cash
plus the assumption of certain liabilities.  The Company recorded a
loss on sale, including taxes, of $269.4 million.  Certain
environmental liabilities, facility leases, and liabilities for
employee benefits, including postretirement benefits, remained with
the Company.  Reserves were established to address the remaining
liabilities.  Earnings, net of taxes, from the animal health segment
for 1997 were $5.8 million.  Interest expense related to debt assumed
by the buyer of $5.6 million for 1997  was included in the above
animal health segment net after-tax results reclassified to
discontinued operations.  During the third quarter of 1998, the
Company recorded a one-time, after-tax charge of $7.9 million to
discontinued operations related to settlement costs from the sale of
the animal health segment.

Discontinued operations for 1997 included other charges, primarily for
environmental and litigation costs related to previously divested
operations, of $2.6 million.

The following schedule summarizes the components, net of tax, of
discontinued operations presented in the Consolidated Statements of
Operations (in millions).

The catalysts and chemical additives and Aero Systems divisions were
reclassified to discontinued operations effective June 30, 1998.
Fries & Fries, Inc. and the animal health segment were reclassified to
discontinued operations effective December 31, 1996 and March 31,
1997, respectively.  All prior periods of the Consolidated Statements
of Operations and Consolidated Balance Sheets were reclassified to

Exit Activities and Restructuring Charges

Immediately after the acquisition of Nellcor was consummated,
management of the combined Company formulated an integration plan to
combine Mallinckrodt and Nellcor into one company.  Since both
companies (Mallinckrodt and Nellcor) had global healthcare operations,
senior management, through transition teams, assessed which activities
should be consolidated.  Management finalized and approved a Nellcor
integration plan during 1998.  Accordingly, the Company recorded
additional purchase liabilities during 1998 of $50.1 million, $30.8
million net of related tax benefit, which were included in the
acquisition cost allocation and related goodwill.  The principal
actions of the plan included the involuntary severance of
approximately 450 Nellcor employees as a result of work force
reduction primarily in U.S. administrative areas at a cost of $37.2
million, relocation of Nellcor employees at a cost of $3.8 million,
and the elimination of contractual obligations of Nellcor which had no
future economic benefit at a cost of $9.1 million.  The actual number
of employees terminated was 425.  Approximately $45.4 million of cash
expenditures were incurred through June 30, 1999 and liabilities of
$1.6 million related to the Nellcor integration plan remained in
accrued liabilities at June 30, 1999.  In June 1999, the estimated
liability was reduced by $3.1 million, $1.9 million net of related tax
benefit, with a corresponding $1.9 million reduction of goodwill
primarily as a result of reduced severance costs.  The remaining cash
expenditures will occur in 2000 and, although none are expected,
further reductions in the estimated liability for these integration
activities will be offset against the related goodwill.

During 1998, the Company recorded a pretax charge to selling,
administrative and general expenses of $19.1 million associated with
exiting certain activities related to Mallinckrodt operations.  The
charge included severance costs of $17.1 million related to the
involuntary severance of approximately 130 Mallinckrodt employees as a
result of work force reduction primarily in the Europe administration
function and U.S. sales force, and facility exit costs of $2.0 million.
The actual number of employees terminated was 115.  Approximately
$14.5 million of cash expenditures have been incurred through June 30,
1999.  In June 1999, the associated accrual was reduced by $.7 million
and credited to selling, administrative and general expenses.  The
remaining $3.9 million cash expenditures will occur in 2000.  No
further adjustments to the reserve are anticipated.

The diluted share base for the year ended June 30, 1998 excluded

NOTE 9 - FINANCIAL INSTRUMENTS

Derivative Financial Instruments

In the ordinary course of business, Mallinckrodt purchases materials
and sells finished products denominated in approximately 25 different
currencies.  The Company is primarily exposed to changes in exchange
rates of the German deutsche mark and other Euro currencies, the
Japanese yen and the Australian dollar.  Overall, the Company is a net
beneficiary when the U.S. dollar weakens and is adversely affected by
a stronger U.S. dollar relative to the major currencies identified.

The Company enters into forward foreign exchange contracts and
currency swaps to minimize the exposure on intercompany financing
transactions.  To mitigate the short-term effect of changes in foreign
currency exchange rates on the Company's consolidated performance, the
Company hedges a portion of its non-U.S. dollar denominated exposures
by purchasing currency options which generally have terms of two years
or less.  The Company uses the currency options with an objective of
limiting negative foreign exchange rate effects on overall performance
for both budget and prior year comparisons over a rolling 18- to 24-
month horizon.  The Company seeks to have effective coverage levels
over such 18- to 24-month horizon of 50 to 80 percent of currency
exposures that subject the Company to risk.  There are no hedging
gains or losses that are explicitly deferred at June 30, 1999.

The Company's interest income and expense are most sensitive to
changes in the general level of U.S. interest rates.  In this regard,
changes in U.S. interest rates affect the interest earned on the
Company's cash equivalents and short-term investments as well as
interest paid on its short-term debt.  To mitigate the impact of
fluctuations in U.S. interest rates, the Company periodically enters
into interest rate swaps and option contracts.

purpose and fair value of instruments outstanding as of June 30, 1999

</TABLE>

Fair Value of Financial Instruments

Non-derivative financial instruments included in the Consolidated
Balance Sheets are cash, short-term investment vehicles, short-term
debt and long-term debt.  In the aggregate, these instruments were
carried at amounts approximating fair value at June 30, 1999 and 1998.
The fair value of long-term debt was estimated based on future cash
flows discounted at current interest rates available to the Company
for debt with similar maturities and characteristics.  See Note 13 for
the disclosure of fair value of long-term debt.

Concentrations of Credit Risk

Financial instruments which expose Mallinckrodt to credit risk are
short-term investments (cash equivalents), trade receivables and
derivatives.  The Company mitigates the risk that counterparties to
short-term investments and derivatives will fail to perform by
contracting only with major financial institutions having high credit
ratings.  Mallinckrodt considers the likelihood of counterparty
failure to be remote.

Trade receivables stem from the Company's worldwide operations and
reflect Mallinckrodt's diverse customer base.  The Company
periodically assesses the financial strength of its customers and
obtains proof of creditworthiness, as necessary, prior to extending
credit.  Consequently, Mallinckrodt does not have a material
concentration of credit risk, either by transaction type, product line
or geographic region.

In January 1998, the Company issued $200 million aggregate principal
amount of notes maturing January 14, 2010.  The notes bear interest at
5.99 percent until January 14, 2000, at which time the interest rate
will be reset at a fixed annual rate of 5.64 percent plus the
Company's then incremental borrowing rate above the rate quoted on
U.S. Treasury ten-year notes.  The notes are redeemable at the
election of the holder, in whole but not in part, at 100 percent of
the principal amount on January 14, 2000.  These notes have been
classified as short-term at June 30, 1999.

In March 1998, the Company issued $200 million aggregate principal
amount of notes maturing March 15, 2011.  The notes bear interest at
6.3 percent until March 15, 2001, at which time the interest rate will
be reset at a fixed annual rate of 5.6219 percent plus the Company's
then incremental borrowing rate above the rate quoted on U.S. Treasury
ten-year notes.  The notes are redeemable at the election of the
holder, in whole but not in part, at 100 percent of the principal
amount on March 15, 2001.  In conjunction with this issue, the Company

periodic interest payment is equal to three-month LIBOR plus .3419
percent.  The rate is adjusted every three months starting June 15,
1998.  The swap contract expires on March 15, 2001.

Proceeds of both of the above transactions were used to repay
commercial paper borrowings.

Maturities of long-term debt for the next five years are: 2000-$203.7
million; 2001-$200.5 million; 2002-$1.4 million; 2003-$15.5 million;
and 2004-$115.5 million.  The 9.875 percent debentures are redeemable

For measurement purposes, annual rates of increase in the per capita
cost of covered healthcare benefits of 7.5 percent and 8.0 percent
were assumed for 2000 and 1999, respectively, gradually declining to
4.75 percent for 2006 and thereafter.  Assumed healthcare cost trend
rates have a significant effect on the amounts reported for the
healthcare plans for retired employees.  A one-percentage-point change
in assumed healthcare cost trend rates would have the following
effects on 1999 service and interest cost and the accumulated
postretirement benefit obligation at June 30, 1999 (in millions):

The net actuarial gain/loss in excess of 10% of the greater of the
benefit obligation and the fair value of plan assets, the prior
service cost and the transition asset/obligation are being amortized
on a straight-line basis over the average remaining service period of
active participants at the date established.

Defined contribution pension and investment plan expense for 1999,
1998 and 1997 was $12.1 million, $12.6 million and $12.5 million,
respectively.  Expenses related to the plans consist primarily of
Company contributions, which include discretionary amounts determined
on an annual basis for certain investment plans.

The pension and postretirement healthcare benefit plan information
presented above includes related amounts for the businesses sold in
1999, 1998 and 1997, except for 1997 pension expense, assets and
liabilities of non-U.S. animal health segment pension plans and the
accrued postretirement benefit cost of certain active animal health
segment employees which were assumed by the buyer.  Mallinckrodt
retained all pension assets and liabilities relating to the frozen
pension benefits of U.S. employees of the businesses sold in 1999,
1998 and 1997.

The foreign currency translation adjustments are not adjusted for
income taxes as they relate to indefinite investments in non-U.S.
subsidiaries.  The change in foreign currency translation during 1997
was net of a $9.3 million translation loss included in discontinued
operations and related to the divestiture of Fries & Fries, Inc. and
the sale of the animal health segment.

The change in unrealized gains (losses) on securities during 1998
included reclassification adjustments of $.2 million of losses
realized from the sale of securities with no tax benefit.  The tax
effects on the components of other comprehensive income (loss) for
1999, 1998 and 1997 were benefits of $2.3 million, $.9 million and
zero, respectively.

NOTE 17 - STOCK PLANS

The Company authorized a new non-qualified stock option plan in
October 1997.  This plan provides for granting stock options at prices
not less than 100 percent of market price (as defined) at the date of
grant.  Options are exercisable over nine years beginning one year
after the date of grant and are limited for the first and second year
of eligibility to 33-1/3 percent and 66-2/3 percent, respectively.
Options granted under previous non-qualified stock option plans are
exercisable over nine years beginning one year after the date of grant
and are limited to 50 percent during the first year of eligibility.

The pro forma information regarding net earnings and earnings per
share required by SFAS 123 has been determined as if the Company had
accounted for its employee stock options under the fair value method.
The fair value for these options was estimated at the date of grant
using the Black-Scholes option pricing model with the following
weighted-average assumptions:

                                         1999       1998      1997

Risk free interest rate..............    5.75%      5.95%     6.32%
Expected dividend yield of stock.....    1.84%      1.58%     1.53%
Expected volatility of stock.........    22.3%      23.8%     25.4%
Expected life of option (years)......     4.6        4.6       4.5

The weighted-average fair values of options granted during 1999, 1998
and 1997 were $6.35, $9.39 and $11.09, respectively.

The estimated fair value of the options is amortized to expense over
the options' vesting period.  The Company's pro forma information
follows (in millions, except per share amounts):

                                         1999       1998       1997

NOTE 18 - BUSINESS SEGMENT AND GEOGRAPHICAL DATA

Upon adoption of SFAS 131, the Company segregated its operations into
three reportable segments:  Respiratory, Imaging and Pharmaceuticals.
The Company's reportable segments are business units that offer
different products and services and are managed separately, because
each business requires different manufacturing, technology and
marketing strategies.

The Respiratory segment develops, manufactures and sells products that
help diagnose, monitor and treat respiratory disorders.  Respiratory
products include anesthesia and respiratory devices; oximetry,
including monitors and sensors; critical care and portable
ventilators; medical gas, oxygen therapy and asthma management; sleep
diagnostic and therapy; blood analysis products; and maintenance
services.  The Respiratory segment's products are purchased for use
throughout the hospital, including intermediate care and step-down
units, labor and delivery rooms, emergency rooms and general care
floors, and are marketed and sold into the alternate site care market,
including surgicenters, subacute care and skilled nursing facilities,
physicians' offices, clinics, ambulatory care settings, and the
growing home market.  These products are sold in the major markets of
the world principally through a direct sales force, assisted by
clinical consultants and specialists, corporate account managers, and
distributors in the United States and internationally.

The Imaging segment manufactures, sells and distributes products used
in radiology, cardiology and nuclear medicine.  Radiology and
cardiology products include x-ray contrast media (ionic and nonionic),
ultrasound contrast agents, magnetic resonance imaging (MRI) agents,
and catheters for use in diagnosis and therapy.  These products are
marketed throughout the world through a direct sales force and
distributors.  Nuclear medicine products consist of
radiopharmaceuticals used to provide images of numerous body organs,
anatomy and function, and to diagnose and treat diseases.  Nuclear
medicine products are sold in the U.S. by a direct sales force and
distributed both directly and through a nationwide network of nuclear
pharmacies.  Internationally, nuclear medicine products are marketed
through a direct sales force and distributors.

The Pharmaceuticals segment includes analgesics such as acetaminophen
(APAP) used to control pain and fever; codeine salts, morphine and
other opium based narcotics and synthetic narcotics used to treat pain
and coughs; and peptides which are used in many new pharmaceuticals.
Other Pharmaceuticals' products include laboratory chemicals used in
analysis and microelectronic chemicals used in the semiconductor
industry; magnesium stearate for use as a tableting aid in
pharmaceuticals; potassium chloride for use as a potassium supplement
in pharmaceuticals and nutritionals; and other salts, chemicals and
reagents used in the production of pharmaceutical and food products.
The Pharmaceuticals products are sold primarily through distributors
and by a direct sales force to the pharmaceutical industry for use in
the manufacture of dosage form drugs.  Narcotic prescription chemicals
are sold directly to pharmaceutical manufacturers, and pharmaceutical
dosage products are sold directly to drug wholesalers and chain
pharmacies, while opiate addiction products are sold primarily to
clinics.  Laboratory chemical products, which include thousands of
high-purity reagent chemicals used in research and development and
analytical laboratories, are sold primarily through distributors to
medical, industrial, educational and governmental laboratories.  A
direct sales force is used to offer microelectronic chemicals and
photoresist strippers to semi-conductor chip producers worldwide.

The Company evaluates performance and allocates resources based upon
operating earnings.  Operating earnings of a business segment
represents revenues less all operating expenses and does not include
interest and corporate expense.  Identifiable segment assets are those
identified as directly attributable to a segment's operations and
primarily include accounts receivable, inventory, property, plant and
equipment, intangible assets and goodwill.

The accounting policies of the reportable segments are the same as
those described in Note 1.

The following information by segment is as of and for the years ended
June 30 (in millions):

On August 28, 1997, the Company acquired Nellcor.  The acquisition was
accounted for under the purchase method of accounting.  The purchase
price of the Nellcor acquisition was approximately $1.9 billion and
was allocated to the assets acquired and liabilities assumed based
upon generally accepted accounting principles and estimated fair
values at the date of acquisition.  Purchased research and
development, an identifiable intangible asset, of $306.3 million was
charged to continuing operations in the first quarter of 1998.  The
sale of Nellcor inventories, which were stepped up to fair value in
connection with allocation of purchase price, decreased earnings from
continuing operations before income taxes by $74.4 million.  In
addition, the Company recorded pretax integration-related charges of
$68.6 million in 1998.  See Note 2 for additional information.

Net sales in the U.S. based upon location of the customers were $1.74
billion, $1.59 billion and $1.08 billion for 1999, 1998 and 1997,
respectively.  The U.S. represents 68 percent, 67 percent and 64
percent of total net sales for 1999, 1998 and 1997, respectively.  No
other individual country had revenues representing 10 percent or more
of total net sales during this three-year period.

Property, plant and equipment, net located in the U.S. were $676
million, $688 million and $560 million for 1999, 1998 and 1997,
respectively.  The U.S. represents 78 percent, 77 percent and 76
percent of the total property, plant and equipment for 1999, 1998 and
1997, respectively.  No other individual country had property, plant
and equipment, net representing 10 percent or more of this asset
category during this three-year period.

In July 1996, Mallinckrodt began supplying Premier with x-ray contrast
media under a five-year contract.  Subsequently, Mallinckrodt entered
into a sole-source agreement to supply Premier hospital and healthcare
facilities with tracheostomy tubes, temperature monitoring systems,
and radiopharmaceuticals and related products.  Effective July 1,
1997, Premier named Mallinckrodt a corporate partner and, accordingly,
Premier's 1,800 hospital and healthcare facilities are provided
incentives to use Mallinckrodt products.  Effective July 1, 1999, the
corporate agreement was extended through December 31, 2006.  In
addition, the new agreement with the inclusion of Nellcor products now
covers almost all Respiratory and Imaging segment products.  For 1999,
1998 and 1997, net sales to hospital and healthcare facilities under
the Premier agreement represented approximately 13 percent, 13 percent
and 9 percent, respectively, of consolidated net sales.  No individual
customer, either through Premier or otherwise, represented more than
10 percent of net sales for any of the three years in the period ended
June 30, 1999.

NOTE 19 - COMMITMENTS

The Company leases office space, data processing equipment, land,
buildings, and machinery and equipment.  Rent expense for continuing
operations in 1999, 1998 and 1997 related to operating leases was
$32.1 million, $31.5 million and $20.2 million, respectively.  Minimum
rent commitments for continuing operations at June 30, 1999 under
operating leases with an initial or remaining noncancelable period

NOTE 20 - CONTINGENCIES

The Company is subject to various investigations, claims and legal
proceedings covering a wide range of matters that arise in the
ordinary course of its business activities.  In one such matter,
German authorities seized certain records of two of the Company's non-
U.S. subsidiaries, Mallinckrodt Medical GmbH and Mallinckrodt
Radiopharma GmbH, in the fall of 1997.  These seizures were part of
investigations of certain practices at these subsidiaries that
involved payments to physicians and other German healthcare providers.
The investigations, which are ongoing, appear to focus on whether the
payments in question were for research or other services performed by
the recipients, or may have been sales incentives or discounts which
could possibly be contrary to German law.

The Company has recognized the costs and associated liabilities only
for those investigations, claims and legal proceedings for which, in
its view, it is probable that liabilities have been incurred and the
related amounts are estimable.  Based upon information currently
available, management believes that existing accrued liabilities are
sufficient and that it is not reasonably possible at this time that
any additional liabilities will result from the resolution of these
matters that would have a material adverse effect on the Company's
consolidated results of operations or financial position.

In connection with laws and regulations pertaining to the protection
of the environment, the Company is a party to several environmental
investigations or remediations and, along with other companies, has
been named a "potentially responsible party" for certain waste
disposal sites.  The Company accrues for losses associated with
environmental remediation obligations when such losses are probable
and reasonably estimable.  Accruals for estimated losses from
environmental remediation obligations generally are recognized no
later than completion of the remedial feasibility study.  Such
accruals are adjusted as further information develops or circumstances
change.  Accruals for future expenditures for environmental
remediation are not discounted to their present value. Recoveries, of
which none exist at June 30, 1999 and 1998, of environmental
remediation costs from other parties are recognized as assets when
their receipt is deemed probable.  The Company previously recognized
the costs associated with the investigation and remediation of
Superfund sites, the litigation of potential environmental claims, and
the investigation and remedial activities at the Company's current and
former operating sites for matters that meet the policy set forth
above.  Related accruals at June 30, 1999 and 1998 of $128.8 million
and $129.2 million, respectively, are included in current accrued
liabilities and other noncurrent liabilities and deferred credits.

On August 28, 1997, the Company acquired Nellcor Puritan Bennett
Incorporated (Nellcor) through an agreement to purchase for cash all
of the outstanding shares of common stock of Nellcor for $28.50 per
share.  The aggregate purchase price of the Nellcor acquisition was
approximately $1.9 billion.  Approximately $308.3 million of the
purchase price was allocated to purchased research and development.
This intangible asset, which had no tax benefit, was charged to
results of operations during the first quarter of 1998.  Of the total
charge of $308.3 million, $2.0 million related to the Aero Systems
division which was sold and reclassified to discontinued operations in
the fourth quarter of 1998.

The sale of Nellcor inventories, which were stepped up to fair value
in connection with the allocation of purchase price, decreased
earnings by $75.4 million, $46.7 million net of taxes for 1998.
After-tax charges to the Respiratory segment, which are included in
earnings (loss) from continuing operations, were $11.5 million and
$34.6 million for the first and second quarters, respectively.  After-
tax charges to discontinued operations related to the Aero Systems
division were $.2 million and $.4 million for the first and second
quarters, respectively.

Costs of exiting certain activities related to Mallinckrodt operations
plus integration costs of the combined Mallinckrodt and Nellcor
operations were $68.6 million, $46.4 million net of taxes.  The after-
tax charge increased the loss from continuing operations in the second
quarter by $4.3 million, and reduced earnings from continuing
operations by $8.3 million and $33.8 million in the third and fourth
quarters, respectively.  See the Exit Activities and Restructuring
Charges section of Note 2 of the Notes to Consolidated Financial
Statements for additional disclosure.

The Company sold certain chemical additive product lines in the second
quarter of 1998, and recorded a gain on sale, net of taxes, of $8.7
million.  In the fourth quarter, the Company sold its catalyst
business and Aero Systems division.  The catalyst sale resulted in a
gain, net of taxes, of $60.2 million.  No gain or loss was recognized
on sale of the Aero Systems division.  In June 1998, the Company
committed to the sale of the remaining chemical additives business of
the catalysts and chemical additives division, and closing of the sale
occurred on July 31, 1998.  The net gain on sale of these businesses
and their results of operations were reclassified to discontinued
operations in the fourth quarter of 1998 and previously reported 1998
quarterly financial information was restated at that time.  See the
Discontinued Operations section of Note 2 of the Notes to Consolidated
Financial Statements for additional disclosure.

In the fourth quarter of 1998, the Company elected to early adopt the
provisions of AICPA SOP 98-5, "Reporting on the Costs of Start-Up
Activities" (SOP 98-5), in its financial statements for the year ended
June 30, 1998.  The effect of adoption of SOP 98-5 was to record a
charge of $8.4 million, net of taxes, for the cumulative effect of an
accounting change to expense costs that had previously been
capitalized prior to July 1, 1997.  The approximate effect of the
accounting change for each quarter of the year ended June 30, 1998 was
to increase the net loss $7.7 million or 11 cents per share in the
quarter ended September 30, 1997; reduce the net loss $.6 million or 1
cent per share in the quarter ended December 31, 1997; increase net
earnings $.6 million or 1 cent per share in the quarter ended March
31, 1998; and increase net earnings $.4 million or 1 cent per share in
the quarter ended June 30, 1998.

Net earnings per share for the four quarters of 1998 were less than
full year per share results by three cents due to increases in common
shares outstanding during 1998.

    C.R. Holman, Chief Executive Officer   Dated:  August 4, 1998


                                                       Exhibit 10.20

         EXECUTIVE INCENTIVE COMPENSATION PLAN FOR FISCAL 2000

1.   Purpose.  The purpose of the Executive Incentive Compensation
     -------
     Plan (the "Plan") is to further the growth and success of
     Mallinckrodt Inc. (the "Company") and its subsidiaries by
     providing key employees of the Company with additional incentives
     to contribute to the growth and success of the Company as
     measured by achievement against the objectives set forth in this
     Plan.

2.   Administration.  The Plan shall be administered by the
     --------------
     Organization and Compensation Committee of the Board of Directors
     of the Company (the "Committee").  The Committee is authorized,
     subject to the provisions of the Plan, to establish from time-to-
     time such rules and regulations and make such interpretations and
     determinations as it may deem necessary or advisable for the
     proper administration of the Plan and all such rules,
     regulations, interpretations and determinations shall be binding
     upon all participants in the Plan.

3.   Participation.  Within three (3) months after the beginning of
     -------------
     the Company's fiscal year beginning July 1, 1999 ("Fiscal 2000"),
     the Committee shall designate those key employees who are to
     become participants in the Plan.  Notwithstanding the foregoing,
     the Committee shall have the discretion to designate additional
     participants in the Plan after such three (3) month period if and
     to the extent they are key employees of the Company. Each such
     designation shall be in writing and shall be filed with the Vice
     President, Human Resources of the Company.

4.   Target Incentive Awards.  The Target Incentive Award ("Target
     -----------------------
     Award") for a participant in the Plan for Fiscal 2000 shall be
     the amount (as approved by the Committee) communicated to such
     participant in writing by the Committee or its designee, on or
     before the end of the third month of Fiscal 2000.  Such Target
     Award shall be payable in whole or in part (and if at all) only
     in accordance with the provisions set forth in this Plan.
     Notwithstanding the foregoing or any other provision hereof, all
     Target Awards hereunder shall be indexed against changes in the
     Company's common stock price from the beginning to the end of
     Fiscal 2000 as determined in the following manner:  the amount of
     any Target Award to be used in determining the amount payable to
     a participant hereunder shall be increased or reduced, as
     appropriate, by the percentage change in the Company's common
     stock price calculated by comparing the average of the high and
     low price of the Company's common stock, as reflected on the New
     York Stock Exchange Composite transactions tape ("NYSE Tape"),
     during the last fifteen (15) New York Stock Exchange trading
     dates of Fiscal 2000 against the average of the high and low
     price of the Company's common stock, as reflected on the NYSE
     Tape, during the last fifteen (15) New York Stock Exchange
     trading days of Fiscal 1999.  Unless and to the extent otherwise
     specifically set forth herein, any and all references to a Target
     Award in this Plan shall mean and refer to a Target Award as
     indexed pursuant to the immediately preceding sentence.

5.   Performance Objectives.
     ----------------------
     (a)  Not later than the end of the second month of Fiscal 2000,
          the Committee, after consultation with the Chief Executive
          Officer ("CEO") of the Company, shall establish financial
          performance objectives for the Plan for Fiscal 2000 (the
          "Performance Objectives").

     (b)  Notwithstanding the provisions of paragraph (a) immediately
          above, the Committee may, after consultation with the CEO,
          cause adjustments to be made to the Performance Objectives
          as a consequence of income or loss attributable to any
          business acquired or divested during Fiscal 2000 or any
          other transaction or any adjustment on the books of account
          of the Company occurring during Fiscal 2000 identified by
          the Committee as being of an unusual and nonrecurring
          nature, provided that the Committee shall not so exclude any
          such item unless it shall be satisfied that it was not taken
          into account in arriving at the Performance Objectives for
          Fiscal 2000.

     (c)  Not more than three (3) months after the beginning of Fiscal
          2000, all participants shall be notified of the Performance
          Objectives.  Such Performance Objectives shall not be
          changed unless approved by the Committee upon the
          recommendation of the Chief Executive Officer of the Company
          ("CEO").

6.   Threshold Percentage; Maximum Percentage.
     ----------------------------------------
     (a)  No later than the end of the third month of Fiscal 2000, the
          Committee, after consultation with the CEO, shall establish
          for the participants hereunder a minimum percentage of
          achievement (the "Threshold Percentage") with respect to the
          Performance Objectives.  If the Threshold Percentage is not
          achieved, there will be no payment of incentive awards
          hereunder except as provided in Section 6(c) below.

     (b)  No later than the end of the third month of Fiscal 2000, the
          Committee, after consultation with the CEO, shall establish
          for the participants hereunder a schedule of incentive
          awards to be paid hereunder expressed as a percentage of the
          Target Award for each participant based on the percentage of
          achievement of the Performance Objectives in excess of the
          Threshold Percentage; provided that, in no event will any
          participant be entitled to receive an amount in excess of
          two hundred percent (200%) of his or her Target Award prior
          to indexation to stock price ("Maximum Percentage"), except
          as provided in Section 6(c) or Section 8(d) below.

     (c)  If the Threshold Percentage is not met or the Maximum
          Percentage is exceeded, the Board of Directors may, in
          either case and upon the Committee's recommendation,
          establish a special award pool for distribution to the
          participants in a manner in which the Board of Directors
          shall determine and in an amount which is reasonably related
          to the actual performance of the Company and the
          participants.  The special award pool shall be combined with
          any payment of incentive awards based on achievement of the
          Maximum Percentage as specified in Section 6(b) above.

7.   Payment and Vesting of Incentive Awards.
     ---------------------------------------
     (a)  Except as otherwise provided in Section 8 hereof following a
          Change in Control (as hereinafter defined), promptly after
          the end of Fiscal 2000, the Chief Financial Officer ("CFO")
          of the Company shall report to the CEO and the Committee the
          percentage of achievement of the Performance Objectives with
          respect to the Plan and the stock price indexing of Target
          Awards as calculated pursuant to Section 4 above.  If the
          Threshold Percentage has been exceeded but the Maximum
          Percentage has not been exceeded, the Committee shall
          empower the Vice President, Human Resources and other
          appropriate officers and employees of the Company to make
          payment of incentive awards to the participants in
          accordance with the requirements hereof, including but not
          limited to the provisions of Section 7(c) below.  If either
          the Threshold Percentage has not been attained or the
          Maximum Percentage has been exceeded, the Committee, if it
          determines that it is appropriate to do so, will establish a
          special award pool in accordance with Section 6(c) above to
          be allocated for payment to each individual participant in
          the same proportion as such participant's Target Award bears
          to the total of all Target Awards established hereunder,
          with such adjustments as the Committee deems necessary to
          account for participants who are employed by the Company for
          less than all of Fiscal 2000. Regardless of when payment of
          any awards is to be made to participants hereunder, any
          award to which a participant is entitled hereunder shall,
          absent a Change in Control, become fully vested to the
          account of the participant on the last day of Fiscal 2000.

     (b)  A participant who is otherwise eligible to receive an
          incentive award pursuant to the terms of this Plan must be
          actively employed by the Company (or a subsidiary thereof)
          on the last day of Fiscal 2000 to be eligible to receive any
          portion of an incentive award hereunder.  However, if a
          participant's employment is terminated prior to the last day
          of Fiscal 2000 by reason of the participant's death,
          disability or retirement, the participant (or the
          participant's designated beneficiary in the event of his or
          her death), shall be entitled to receive, [at the sole
          discretion of the Committee,] an amount determined by
          multiplying the incentive award which otherwise would have
          been payable pursuant to this Plan had the participant
          remained an employee through the last day of Fiscal 2000 by
          a fraction, the numerator of which is the number of days
          during Fiscal 2000 that the participant was employed by the
          Company (or a subsidiary thereof) and the denominator of
          which is 365.  For purposes of this Plan, "retirement" means
          retirement at or after age 55, but shall not include any
          termination of a participant for Cause (as defined in
          Section 8(c) hereof).  If a participant hereunder begins
          employment after the first day of Fiscal 2000, the
          participant's incentive award for Fiscal 2000 shall be
          determined by an appropriate proration consistent with the
          intent set forth in this paragraph (b).

     (c)  Unless the participant elects otherwise pursuant to
          paragraph (d) of Section 7 or unless required otherwise
          pursuant to the provisions of paragraph (e) of Section 7,
          payment of incentive awards to participants under the Plan
          with respect to Fiscal 2000 shall be made in cash in a lump
          sum (net of any required withholding taxes) within seventy
          five (75) days after the close of Fiscal 2000.

     (d)  A participant (other than participants that are not either
          United States citizens or permanently resident in the United
          States) may elect to defer payment of his or her actual
          incentive award for Fiscal 2000 by written notice submitted
          to the Committee not later than thirty (30) days after the
          date on which a participant has been provided notice of his
          or her Target Award and the Plan Performance Objectives.  A
          participant electing to defer may have his or her award paid
          in one of the following ways:

          i.  with the consent of the Committee, in a lump sum payment
              or in a series of not less than five (5) nor more than
              ten (10) installments commencing no earlier than seventy
              five (75) days after the end of Fiscal 2000 and not
              later than sixty (60) days after the end of the calendar
              year in which the participant terminates his employment,
              whether by death, disability, normal or early
              retirement, pursuant to the Company's retirement plan,
              or any other reason, it being understood that the
              Committee may, upon request by a participant prior to
              his or her termination of employment, in the Committee's
              sole discretion, deem that any period of consultancy
              with the Company which is commenced immediately upon a
              participant's termination of employment is a
              continuation of employment for purposes of this
              subparagraph (i) only; or

         (ii) with the consent of the Committee, in a lump sum payment
              on any other date or in a series of not less than five
              (5) nor more than ten (10) installments commencing on
              any other date as may be agreed upon by the participant
              and the Committee; provided however, should a
              participant terminate employment prior to such agreed
              upon date, the Committee may, in its sole discretion,
              pay all such participant's awards deferred pursuant to
              this subparagraph (ii), plus interest accrued thereon,
              to such participant no later than sixty (60) days after
              the date of termination of employment.

     All incentive awards hereunder, whether deferred or not, shall be
     payable in cash (net of any required withholding of taxes).

     Notwithstanding the election to defer made by the participant
     pursuant to the foregoing, the Committee in its sole discretion
     may, upon the death or disability of a participant during Fiscal
     2000 and who was still employed at the time of such death or
     disability, pay  such participant's deferred awards under this
     Plan plus accrued interest thereon to the participant or to such
     participant's designated beneficiary (as applicable) in a lump
     sum no later than sixty (60) days after the end of the calendar
     year in which the participant's death or disability occurs.

     A participant's deferred compensation account shall not be
     trusteed, nor will such account represent any obligation on the
     part of the Company other than the contractual obligations
     specified in the applicable award deferral agreement.  The
     Company agrees to accrue interest on the participant's deferred
     compensation account at the end of each month at a rate equal to
     the prime rate being charged or quoted by Citibank on and as of
     the first day of the particular calendar quarter in which such
     month occurs.

     (e)  Notwithstanding any other provision of this Plan that may be
          interpreted to the contrary, the Committee, in its sole
          judgment and discretion, may determine, because of the
          adverse impact of any tax or other laws, rules or
          regulations upon the Company or for the advancement of any
          other corporate purpose, interest or objective, that it is
          necessary or desirable that all or some portion of the
          incentive award otherwise payable to all or any similarly
          situated group of participants in accordance with this Plan
          be deferred until such time or times as payment of all or
          some of such deferred amounts to the participant would not
          subject the Company to any such adverse impact.  Further, it
          is understood that, with respect to a participant who is a
          "covered employee" within the meaning of Section 162(m) of
          the Internal Revenue Code of 1986, as amended, payments of
          incentive awards shall be automatically deferred to the
          extent necessary until such time as either (i) payment of
          all or a portion of any such deferred incentive awards can
          be made to such an employee in a manner that will ensure
          full tax deductibility therefor to the Company or (ii) such
          employee ceases to be a "covered employee".  It is
          understood that no participant in this Plan shall be
          entitled to receive payment of any incentive award hereunder
          or to be a participant in this Plan unless such participant
          shall execute such documents as the Company shall provide
          specifying that participation in the Plan is conditional
          upon the participant's understanding and acceptance of the
          discretionary authority granted to the Committee pursuant to
          this Section 7(e) and Section 9 hereof.  In the event of an
          automatic deferral of all or any portion of a participant's
          incentive award pursuant to this Section 7(e), any such
          deferred amounts shall accrue interest until paid at the
          rate set forth in the last sentence of Section 7(d).

8.   Change in Control.
     -----------------
     (a)  For purposes of the Plan, "Change in Control" means the
          occurrence of any one of the following events:
          (i) any "person" (as such term is defined in Section 3(a)(9)
              of the Securities Exchange Act of 1934 (the "Exchange
              Act") and as used in Sections 13(d)(3) and 14(d)(2) of
              the Exchange Act) is or becomes a "beneficial owner" (as
              defined in Rule 13d-3 under the Exchange Act), directly
              or indirectly, of securities of the Company representing
              20% or more of the combined voting power of the
              Company's then outstanding securities eligible to vote
              for the election of the Board of Directors (the "Company
              Voting Securities"); provided, however, that the event
              described in this subparagraph (i) shall not be deemed
              to be a Change in Control by virtue of any of the
              following acquisitions:  (A) by the Company or any
              subsidiary of the Company, (B) by any employee benefit
              plan sponsored or maintained by the Company or any
              subsidiary of the Company, (C) by any underwriter
              temporarily holding securities pursuant to an offering
              of such securities, (D) pursuant to a Non-Control
              Transaction (as defined in subparagraph (iii) below),
              (E) with respect to any specific participant, pursuant
              to any acquisition by the participant or any group of
              persons including the participant, or (F) except as
              provided in subparagraph (iii) below, in which Company
              Voting Securities are acquired from the Company, if a
              majority of the Board approves a resolution providing
              expressly that such acquisition does not constitute a
              Change in Control under this subparagraph (i);

         (ii) individuals who, on the date of adoption of this
              Executive Incentive Compensation Plan, constitute the
              Board of Directors (the "Incumbent Board") cease for any
              reason to constitute at least a majority thereof,
              provided that any person becoming a director subsequent
              to the date of adoption of this Executive Incentive
              Compensation Plan, whose election, or nomination for
              election, by the Company's stockholders was approved by
              a vote of at least a majority of the directors
              comprising the Incumbent Board (either by a specific
              vote or by approval of the proxy statement of the
              Company in which such person is named as a nominee for
              director, without objection to such nomination) shall
              be, for purposes of this paragraph (ii), considered as
              though such person were a member of the Incumbent Board;
              provided, however, that no individual initially elected
              or nominated as a director of the Company as a result of
              an actual or threatened election contest with respect to
              directors or any other actual or threatened solicitation
              of proxies or consents by or on behalf of any person
              other than the Board of Directors shall be deemed to be
              a member of the Incumbent Board;

        (iii) the consummation of a merger, consolidation, share
              exchange or similar form of corporate reorganization of
              the Company or any such type of transaction requiring
              the approval of the Company's stockholders (whether for
              such transaction or the issuance of securities in the
              transaction or otherwise), or the consummation of the
              direct or indirect sale or other disposition of all or
              substantially all of the assets, of the Company (a
              "Business Combination"), unless immediately following
              such Business Combination:  (A) more than 50% of the
              total voting power of the publicly traded corporation
              resulting from such Business Combination (including,
              without limitation, any corporation which directly or
              indirectly has beneficial ownership of 100% of the
              Company Voting Securities or all or substantially all of
              the Company's assets) eligible to elect directors of
              such corporation is represented by shares that were
              Company Voting Securities immediately prior to such
              Business Combination (either by remaining outstanding or
              being converted), and such voting power is in
              substantially the same proportion as the voting power of
              such Company Voting Securities immediately prior to the
              Business Combination, (B) no person (other than any
              publicly traded holding company resulting from such
              Business Combination, any employee benefit plan
              sponsored or maintained by the Company (or the
              corporation resulting from such Business Combination),
              or any person which beneficially owned, immediately
              prior to such Business Combination, directly or
              indirectly, 20% or more of the Company Voting Securities
              (a "Company 20% Stockholder")) becomes the beneficial
              owner, directly or indirectly, of 20% or more of the
              total voting power of the outstanding voting securities
              eligible to elect directors of the corporation resulting
              from such Business Combination and no Company 20%
              Stockholder increases its percentage of such total
              voting power, and (C) at least a majority of the members
              of the board of directors of the corporation resulting
              from such Business Combination were members of the
              Incumbent Board at the time of the approval of the Board
              of Directors of the execution of the initial agreement
              providing for such Business Combination (any transaction
              satisfying (A), (B) and (C) immediately above a "Non-
              Control Transaction"); or

         (iv) the stockholders of the Company approve a plan of
              complete liquidation or dissolution of the Company.


         Notwithstanding the foregoing, a Change in Control of
         the Company shall not be deemed to occur solely because
         any person acquires beneficial ownership or more than
         20% of the Company Voting Securities as a result of the
         acquisition of Company Voting Securities by the Company
         which, by reducing the number of Company Voting
         Securities outstanding, increases the percentage of
         shares beneficially owned by such person; provided that,
         if a Change in Control of the Company would occur as a
         result of such an acquisition by the Company (if not for
         the operation of this sentence), and after the Company's
         acquisition such person becomes the beneficial owner of
         additional Company Voting Securities that increases the
         percentage of outstanding Company Voting Securities
         beneficially owned by such person, then a Change in
         Control of the Company shall occur.

     (b) For purposes of the Plan, "Good Reason" with respect to a
         participant means, without such participant's express
         written consent, the occurrence of any of the following
         events after a Change in Control:

         (i)  (1) the assignment to such participant of any duties or
              responsibilities (including reporting responsibilities)
              inconsistent in any material and adverse respect with
              the participant's duties and responsibilities with the
              Company immediately prior to such Change in Control
              (including any material and adverse diminution of such
              duties or responsibilities), it being understood that
              Good Reason shall not be deemed to occur upon a change
              in duties or responsibilities that is solely and
              directly a result of the Company no longer being a
              publicly traded entity, and does not involve any other
              event set forth in this paragraph (b) or (2) a material
              and adverse change in such participant's titles or
              offices with the Company as in effect immediately prior
              to such Change in Control;

         (ii) a reduction by the Company in such participant's rate of
              annual base salary or target annual bonus or other
              incentive compensation opportunity as in effect
              immediately prior to such Change in Control or as the
              same may be increased from time to time thereafter;

        (iii) any requirement of the Company that such participant (1)
              notwithstanding his or her objection, be based anywhere
              more than fifty (50) miles from the location where the
              participant's employment is located at the time of the
              Change in Control or (2) travel on Company business to
              an extent substantially greater than the travel
              obligations of the participant immediately prior to such
              Change in Control; or

         (iv) the failure of the Company to (1) continue in effect any
              employee benefit plan or compensation plan in which such
              participant is participating immediately prior to such
              Change in Control (including the taking of any action by
              the Company which would adversely affect the
              participant's participation in or materially reduce the
              participant benefits under any such plan), unless the
              participant is permitted to participate in other plans
              providing the participant with substantially comparable
              benefits, (2) provide such participant and the
              participant's dependents with welfare benefits in
              accordance with the most favorable plans, practices,
              programs and policies of the Company and its affiliated
              companies in effect for the participant immediately
              prior to such Change in Control or provide substantially
              comparable benefits at a substantially comparable cost
              to the participant, (3) provide fringe benefits in
              accordance with the most favorable plans, practices,
              programs and policies of the Company and its affiliated
              companies in effect for such participant immediately
              prior to such Change in Control, or provide
              substantially comparable fringe benefits, or (4) provide
              such participant with paid vacation in accordance with
              the most favorable plans, policies, programs and
              practices of the Company and its affiliated companies as
              in effect for the participant immediately prior to such
              Change in Control (including crediting the participant
              with all service credited to him or her for such purpose
              prior to the Change in Control), unless the failure to
              provide such paid vacation is a result of a policy
              uniformly applied by the entity acquiring the Company to
              its employees.

              Notwithstanding the foregoing portions of this paragraph
              (b), an isolated and inadvertent action taken in good
              faith and which is remedied by the Company within ten
              (10) days after receipt of notice thereof given by the
              participant shall not constitute Good Reason.  The
              participant must notify the Company of an event
              constituting Good Reason within ninety (90) days
              following his or her knowledge of its existence or such
              event shall not constitute Good Reason under the Plan.

     (c)  For purposes of the Plan, "Cause" means with respect to a
          participant (i) the willful and continued failure of such
          participant substantially to perform his or her duties with
          the Company (other than any failure due to physical or
          mental incapacity) after a demand for substantial
          performance is delivered to him or her by the Committee
          which specifically identifies the manner in which the
          Committee believes he has not substantially performed his or
          her duties or (ii) willful misconduct materially and
          demonstrably injurious to the Company.  No act or failure to
          act by a participant shall be considered "willful" unless
          done or omitted to be done by him or her not in good faith
          and without reasonable belief that his or her action or
          omission was in the best interest of the Company.  The
          unwillingness of a participant to accept any condition or
          event which would constitute Good Reason under paragraph (b)
          of this Section 8 may not be considered by the Committee to
          be a failure to perform or misconduct by a participant.  The
          Company must notify the participant of an event constituting
          Cause within ninety (90) days following its knowledge of the
          event's existence or such event shall not constitute Cause
          under the Plan.

     (d)  If a Change in Control of the Company occurs at any time
          during Fiscal 2000, and a participant's employment with the
          Company and its subsidiaries is terminated at any time after
          such Change in Control but on or prior to the last day of
          Fiscal 2000 and such termination is effected (i) by the
          Company (other than for Cause, disability (within the
          meaning of the Company's long-term disability plan) or
          mandatory retirement) or (ii) by the participant for Good
          Reason, then (in the event of either of the foregoing) such
          participant shall be paid, within thirty (30) days following
          such termination of employment, a lump sum cash amount (net
          of any required withholding taxes) equal to such
          participant's Target Award for Fiscal 2000.  Further, with
          respect to a situation in which an incentive award under
          this Plan has been deferred (whether voluntarily by a
          participant, by action of the Committee or by operation of
          the terms of this Plan), if a Change in Control of the
          Company occurs after the end of Fiscal 2000 but prior to the
          payment or distribution to a participant of any such
          incentive award, and a participant's employment with the
          Company and its subsidiaries is terminated after the end of
          the Fiscal 2000 and after such Change in Control occurs and
          such termination is effected (i) by the Company (other than
          for cause, disability (within the meaning of the Company's
          long-term disability plan) or mandatory retirement) or (ii)
          by the participant for Good Reason, then (in the event of
          all of the foregoing) such participant shall be paid, within
          thirty (30) days following such termination of employment, a
          lump sum cash amount (net of any required withholding taxes)
          equal to such participant's Target Award for Fiscal 2000
          notwithstanding any such deferral.

     (e)  In the event a Change in Control of the Company occurs at
          any time during Fiscal 2000, each participant who thereafter
          remains employed by the Company as of the end of Fiscal 2000
          shall receive, in lieu of any other amounts payable
          hereunder, an annual incentive award under this Plan with
          respect to Fiscal 2000 equal to two (2) times his or her
          Target Award for Fiscal 2000.

     (f)  Notwithstanding anything in this Plan to the contrary, this
          Section 8 may not be amended, modified or terminated in a
          manner adverse to the participants during a period of one
          year and two (2) months immediately following a Change in
          Control of the Company.

     (g)  Notwithstanding anything in paragraph (c) of Section 5 to
          the contrary, in the event a Change in Control of the
          Company occurs during Fiscal 2000 then, at any time during
          or with respect to the remainder of Fiscal 2000, the
          Committee may not adjust Performance Objectives or Target
          Awards hereunder in any manner adverse to any one or more of
          the participants.

     (h)  Anything in this Plan to the contrary notwithstanding, in
          the event it shall be determined that any payment or
          distribution by the Company of an incentive award pursuant
          to this Section 8 (any such award referred to herein as a
          "Change of Control Payment") to or for the benefit of a
          participant (determined without regard to any additional
          payments required under this paragraph (h)) would be subject
          to the excise tax imposed by Section 4999 of the Internal
          Revenue Code of 1986, as amended, or any interest or
          penalties are incurred by a participant with respect to such
          excise tax (such excise tax, together with any such interest
          and penalties, are hereinafter collectively referred to as
          the "Excise Tax"), then the participant shall be entitled to
          receive an additional payment (a "Gross-Up Payment") in an
          amount such that, after payment by the participant of all
          taxes, including any interest or penalties imposed with
          respect to such taxes (including, without limitation, any
          income and employment taxes, and any interest and penalties
          imposed with respect thereto, and Excise Tax imposed upon
          the Gross-Up Payment), the participant retains an amount of
          the Gross-Up Payment equal to the Excise Tax imposed upon
          the Change of Control Payment made to the participant
          pursuant to this Plan.  For purposes of determining the
          amount of the Gross-Up Payment, a participant shall be
          deemed to pay federal income taxes at the highest marginal
          rates of federal income taxation for the calendar year in
          which the Gross-Up Payment is to be made and applicable
          state and local income taxes at the highest marginal rate of
          taxation for the calendar year in which the Gross-Up Payment
          is to be made, net of the maximum reduction in federal
          income taxes which could be obtained from deduction of such
          state and local taxes.  All determinations required to be
          made under this paragraph (h), including whether and when a
          Gross-Up Payment is required and the amount of such Gross-Up
          Payment and the assumptions to be utilized in arriving at
          such determination, shall be made by the public accounting
          firm that is retained by the Company as of the date
          immediately prior to the Change in Control (the "Accounting
          Firm"), which Accounting Firm shall provide detailed
          supporting calculations both to the Company and the
          participant within fifteen (15) business days of the receipt
          of notice from the Company or the participant that there has
          been a Change of Control Payment, or such earlier time as is
          requested by the Company (collectively, the
          "Determination").  In the event that the Accounting Firm is
          serving as accountant or auditor for the individual, entity
          or group effecting the Change in Control, the participant
          may appoint another nationally recognized public accounting
          firm to make the determinations required hereunder (which
          accounting firm shall then be referred to as the Accounting
          Firm hereunder).  All fees and expenses of the Accounting
          Firm shall be borne solely by the Company and the Company
          shall enter into any reasonable agreement requested by the
          Accounting Firm in connection with the performance of the
          services hereunder.  The Gross-Up Payment under this
          paragraph (h) should be made within thirty (30) days of any
          Change of Control Payment.  If the Accounting Firm
          determines that no Excise Tax is payable by the participant,
          it shall furnish the participant with a written opinion that
          failure to report the Excise Tax on the participant's
          applicable federal income tax return would not result in the
          imposition of a negligence or similar penalty.  The
          Determination by the Accounting Firm shall be binding upon
          the Company and the participant.  As a result of the
          uncertainty in the application of Section 4999 of the Code
          at the time of the Determination, it is possible that Gross-
          Up Payments will be made by the Company which should not
          have been made ("Overpayment"), consistent with the
          calculations required to be made hereunder.  In the event
          that the participant thereafter is required to make payment
          of any additional Excise Tax, the Accounting Firm shall
          determine the amount of the Underpayment that has occurred
          and any such Underpayment (together with interest at the
          rate provided in Section 1274(b)(2)(B) of the Code) shall be
          promptly paid by the Company to or for the benefit of the
          participant.  In the event the amount of the Gross-Up
          Payment exceeds the amount necessary to reimburse the
          participant for his Excise Tax, the Accounting Firm shall
          determine the amount of the Overpayment that has been made
          and any such Overpayment (together with interest at the rate
          provided in Section 1274(b)(2) of the Code) shall be
          promptly paid by the participant to or for the benefit of
          the Company.  The participant shall cooperate, to the extent
          his expenses are reimbursed by the Company, with any
          reasonable requests by the Company in connection with any
          contests or disputes with the Internal Revenue Service in
          connection with the Excise Tax.  The provisions of this
          paragraph (h) shall be coordinated with any substantially
          similar provisions contained in any plan or agreement
          covering the participant and calling for payment by the
          Company (under appropriate circumstances) of any bonus,
          award, benefit or other compensation, with the intent and
          effect that the participant shall be made whole for the
          effect of all Excise Taxes levied on the participant as a
          consequence of payments made under such plans or agreements
          but shall not receive any windfall or double payment.

     (i)  Any payments made by the Company to a participant pursuant
          to either Sections 8(d) or 8(e) above shall be deemed to be
          in lieu of and not in addition to any amounts a participant
          might otherwise be entitled to receive pursuant to the
          provisions of Section 7 hereof.

9.   Forfeiture of Awards.  The Committee may, in its sole discretion,
     --------------------
     in the event of a serious breach of conduct by a participant
     (including, without limitation, any conduct prejudicial to or in
     conflict with the Company or its subsidiaries) or any activity of
     a participant in competition with the business of the Company or
     any subsidiary, (i) cancel any incentive award, in whole or in
     part, whether or not vested or deferred, and/or (ii) if such
     conduct or activity occurs within one (1) year following the
     payment of any incentive award, require the participant to repay
     to the Company some or all of the amount of any incentive award.
     Such cancellation or repayment obligation shall be effective as
     of the date specified by the Committee, and the Committee may
     provide for an offset to any future payments owed by the Company
     or any subsidiary to the participant under this Plan if necessary
     to satisfy the repayment obligation.  The determination of
     whether a participant has engaged in a serious breach of conduct
     or any activity in competition with the business of the Company
     or any subsidiary shall be determined by the Committee in good
     faith and in its sole discretion.

10.  Miscellaneous.
     -------------
     (a)  By action of the Board of Directors, the Plan may be amended
          at any time and from time to time, or terminated at any
          time, provided, however, that no such amendment shall divest
          any participant of rights which have been accrued under the
          Plan.

     (b)  The rights of a participant under the Plan are personal to
          the participant and to any person or persons who may become
          entitled to distributions or payments under the Plan by
          reason of the death of the participant, and the rights of
          the participant or any such person under the Plan shall not
          be subject to voluntary or involuntary alienation,
          assignment or transfer by the participant or any such person
          or persons.

     (c)  The obligations of the Company under the Plan shall be
          binding upon any successor corporation or organization which
          shall succeed to substantially all of the assets and
          business of the Company and the term "Company" wherever used
          in this Plan shall mean and include any such corporation or
          organization after such succession.

     (d)  No participant shall have any right to be retained in the
          employ of the Company by virtue of participation in the
          Plan.

     (e) If, at any time prior to the payment or delivery of any
         incentive awards under this Plan, mandatory wage controls
         are in effect which, in the opinion of counsel to the
         Company, are applicable to this Plan and would make such
         incentive awards or the payments or delivery thereof in
         accordance with the Plan illegal, the Committee shall reduce
         the amount of such incentive awards, payments or deliveries
         in such manner and to such extent (including elimination of
         such incentive awards) as, in its sole judgment, are
         necessary or advisable in order to comply with such
         applicable law.  If, at any time prior to such payment or
         delivery under the Plan, voluntary wage controls are in
         effect under any federal policy with respect to wage
         controls and if any such incentive awards or the payments or
         delivery thereof as provided for in the Plan would, in the
         opinion of counsel to the Company, exceed applicable
         guidelines established under such voluntary controls, the
         Committee may, in its absolute discretion and if it deems it
         to be in the interest of the Company, reduce or eliminate
         the amount of such incentive awards, payments or deliveries
         in such manner and to such extent as it deems advisable.

     (f) This Plan is intended to constitute an "unfunded" plan for
         incentive and deferred compensation.  Nothing contained in
         this Plan shall give the participants any rights with
         respect to any incentive award that are greater than those
         of a general creditor of the Company.

     (g) This Plan sets forth all of the terms and conditions
         applicable to its subject matter and no other prior or
         future plan, agreement or understanding, whether written or
         oral, shall have any effect on the interpretation, validity
         or enforceability hereof.

     (h) Unless the context otherwise requires, words in the singular
         include the plural and words in the plural include the
         singular.

     (i) The Plan shall be governed by and construed in accordance
         with the laws of the State of New York, regardless of the
         effect of such state's conflict of laws principles.

                  (As amended through August 18, 1999)

                                Article I
                                ---------

                         MEETINGS OF STOCKHOLDERS

Section 1.   The annual meeting of stockholders of this Corporation
- ----------
for the election of directors and the transaction of such other
business as may properly come before the meeting shall be held on such
day of each year and at such place and hour as may be fixed by the
Board of Directors prior to the giving of the notice of the date,
place, and object of such meeting, or if no other date has been so
fixed, on the third Wednesday in October.   Notice of the time, place
and object of such meeting shall be given by mailing at least ten days
previous to such meeting, postage prepaid, a copy of such notice
addressed to each stockholder at his residence or place of business as
the same shall appear on the books of the Corporation.

Section 2.   Special meetings of the stockholders other than those
- ----------
regulated by statute may be called at any time by the Chairman of the
Board, the President or by a majority of directors.  Notice of every
special meeting stating the time, place and object thereof, shall be
given by mailing, postage prepaid, at least ten days before such
meeting, a copy of such notice addressed to each stockholder at his
post office address as the same appears on the books of the
Corporation.

Section 3.   At all meetings of stockholders a majority of the votes
- ----------
of capital stock outstanding and entitled to vote thereat either in
person or by proxy, shall constitute a quorum, except as may be
otherwise provided by law.

Section 4.   The Board of Directors may fix a date not more than sixty
- ----------
days prior to the day of holding any meeting of stockholders as the
day as of which stockholders entitled to notice of and to vote at such
meeting shall be determined.

Section 5.   At all meetings of stockholders all questions shall be
- ----------
determined by a majority of the votes cast by the holders of shares
entitled to vote thereon in person or by proxy, except as otherwise
provided by law.

Section 6.   Except as may otherwise be required by applicable law
- ----------
or regulation, a stockholder may make a nomination or nominations for
director of the Corporation at an annual meeting of stockholders or at
a special meeting of stockholders called for the purpose of electing
directors or may bring up any other matter for consideration and
action by the stockholders at an annual meeting of stockholders only
if the provisions of Subsections A, B and C hereto shall have been
satisfied.  If such provisions shall not have been satisfied, any
nomination sought to be made or other business sought to be presented
by a stockholder for consideration and action by the stockholders at
the meeting shall be deemed not properly brought before the meeting,
is and shall be ruled by the chairman of the meeting to be out of
order, and shall not be presented or acted upon at the meeting.

     A.  The stockholder must, not less than ninety days and not more
than one hundred and twenty days before the day of the meeting,
deliver or cause to be delivered a written notice to the Secretary of
the Corporation; provided, however, that in the event that less than
one hundred days' notice or prior public disclosure of the date of the
meeting is given or made to the stockholders by the Corporation,
notice by the stockholder to the Secretary of the Corporation, to be
timely, must be received not later than the close of business on the
tenth day following the day on which such notice or prior public
disclosure was made.  Notice by the Corporation shall be deemed to
have been given more than one hundred days in advance of the annual
meeting if the annual meeting is called for the third Wednesday in
October (or on any day within a thirty day period before or after such
date, provided that in any such case the third Wednesday in October
shall be deemed the "day of the meeting" for purposes of calculating
the ninety and one hundred and twenty day periods set forth above)
without regard for when the notice or public disclosure thereof is
actually given or made.  The stockholder's notice shall specify (a)
the name and address of the stockholder as they appear on the books of
the Corporation; (b) the class and number of shares of the Corporation
which are beneficially owned by the stockholder; (c) any interest of
the stockholder in the proposed business described in the notice which
is in the interest of a business or object other than the business of
the Corporation; (d) if such business is a nomination for director,
each nomination sought to be made and a statement signed by each
proposed nominee indicating his or her willingness so to serve if
elected and disclosing the information about him or her that is
required by the Securities Exchange Act of 1934 and the rules and
regulations promulgated thereunder to be disclosed in the proxy
materials for the meeting involved if he or she were a nominee of the
Corporation for election as one of its directors; and (e) if such
business is other than a nomination for director, a brief description
of such business and the reasons it is sought to be submitted for a
vote of the stockholders.

     Notwithstanding anything in this Section 6 to the contrary, in
the event that the number of directors to be elected to the Board of
Directors of the Corporation is increased and either all of the
nominees for director or the size of the increased Board of Directors
is not publicly announced or disclosed by the Corporation at least 100
days prior to the first anniversary of the preceding year's annual
meeting, a Shareholder Notice shall also be considered timely
hereunder, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary of
the Corporation at the principal executive office of the Corporation
not later than the close of business on the tenth day following the
first date all of such nominees or the size of the increased Board of
Directors shall have been publicly announced or disclosed.

     For purposes of this Section 6, a matter shall be deemed to have
been "publicly announced or disclosed" and "public disclosure" shall
be deemed to have been made if such matter is disclosed in a press
release reported by the Dow Jones News Service, Associated Press or
comparable national news service or in a document publicly filed by
the Corporation with the Securities and Exchange Commission.

     In no event shall the adjournment of an annual meeting, or the
postponement of any annual meeting keeping the same record date, or
any announcement thereof, commence a new period for the giving of
notice as provided in this Section 6.

     B.  Notwithstanding satisfaction of the provisions of Subsection
A, the proposed business described in the notice may be deemed not to
be properly brought before the meeting if, pursuant to state law or to
any rule or regulation of the Securities and Exchange Commission, it
was offered as a stockholder proposal and was omitted, or had it been
so offered, it could have been omitted, from the notice of, and proxy
material for, the meeting (or any supplement thereto) authorized by
the Board of Directors.

     C.  In the event such notice is timely given and the business
described therein is not disqualified because of Subsection B, such
business (a) may nevertheless not be presented or acted upon at a
special meeting of stockholders unless in all other respects it is
properly before such meeting; and (b) may not be presented except by
the stockholder who shall have given the notice required by Subsection
A or a representative of such stockholder who is qualified under the
law of New York to present the proposal on the stockholder's behalf at
the meeting.

Section 7.   Except as may otherwise be required by applicable law or
- ----------
by rules and regulations adopted by the Board of Directors, the Chair
of any meeting of stockholders shall prescribe such rules, regulations
and procedures and do such acts, including causing an adjournment of
the meeting without a vote of stockholders, that the Chair deems
appropriate.  Such rules, regulations or procedures, whether adopted
by the Board or prescribed by the Chair of the meeting, may include,
but are not limited to, the following: (a) the establishment of an
agenda or order of business for the meeting, including fixing the time
for opening and closing the polls for voting on each matter; (b) rules
and procedures for maintaining order at the meeting and the safety of
those present; (c) limitations on attendance at or participation in
the meeting to stockholders of record of the Corporation, their duly
authorized and constituted proxies or such other persons as the Chair
shall permit; (d) restrictions on entry to the meeting after the time
fixed for the commencement thereof; and (e) limitations on the time
allotted for questions or comments by participants.  Unless and to the
extent determined by the Board or the Chair of the meeting, meetings

                                Article II
                                ----------

                                DIRECTORS

Section 1.   The number of directors of the Corporation may be
- ----------
determined from time to time by resolution adopted by a majority of
the entire Board of Directors, except that such number shall not be
less than eight nor more than sixteen, exclusive of directors, if any,
to be elected by the holders of 4% Cumulative Preferred Stock or the
holders of one or more series of Series Preferred Stock pursuant to
the provisions of Article Third of the Certificate of Incorporation of
the Corporation.  Until the first such resolution is adopted, the
Board shall consist of sixteen directors.  As provided in the
Certificate of Incorporation and subject to the provisions of the
ninth sentence of Article Ninth thereof, (i) the directors shall be
divided into three classes as nearly equal in number as possible; (ii)
at each annual meeting directors to replace those whose terms expire
at such annual meeting shall be elected to hold office until the third
succeeding annual meeting and until their successors are chosen; (iii)
if the number of directors is changed, any newly created directorships
or decrease in directorships shall be so apportioned among the classes
as to make all classes as nearly equal in number as possible; and (iv)
if the number of directors is increased by the Board of Directors and
any newly created directorships are filled by the Board, there shall
be no classification of the additional directors until the next annual
meeting of stockholders.  No decrease in the Board shall shorten the
term of any incumbent director.  As used in these By-Laws, "entire
Board of Directors" means the total number of directors which the
Corporation would have if there were no vacancies.  Vacancies
occurring in the Board of Directors may be filled for the unexpired
term by a majority vote of the remaining directors.  The Board of
Directors shall adopt such rules and regulations for the conduct of
the meetings and management of the affairs of the Corporation as they
may deem proper, not inconsistent with the laws of the State of New
York or these By-Laws.  This By-Law may be amended only by the
affirmative vote of the holders of two-thirds of the shares of all
classes of stock of the Corporation entitled to vote in elections of
directors, considered for the purposes of this By-Law as one class.

Section 2.   The directors shall elect one of their members, who may
- ----------
or may not be an officer of the Corporation, to act as Chairman of the
Board.  He shall preside, when present, at all meetings of the Board
of Directors and stockholders.

Section 3.   As soon as practicable after the Annual Meeting of
- ----------
Stockholders, the newly elected Board of Directors shall hold its
first meeting for the purpose of organization and the transaction of
business.  At such organizational meeting the Board of Directors shall
elect the officers of the Corporation and shall prepare a schedule
fixing the time and place of all regular meetings of the Board of
Directors to be held during the next ensuing calendar year.  All such
regular meetings of the Board of Directors may be held without further
notice to any director who shall have attended the organizational
meeting.  Notice of the time and place fixed for such regular meetings
shall be given by personal notice or by mail or telegraph to each
director who shall not have attended the organizational meeting at
least ten days prior to the first Board of Directors' meeting after
such organizational meeting which such director shall be eligible to
attend.  The Board of Directors shall have authority to change the
time and place of any regular meeting previously fixed, provided that
the foregoing provisions as to notice thereof shall apply to any such
changed regular meeting.  The Chairman of the Board of Directors or
the President may, and at the request of a majority of the Board of
Directors in writing must, call a special meeting of the Board of
Directors, not less than twenty-four hours' notice of which must be
given by personal notice or by mail, telephone, telegraph, facsimile
(FAX), or other form of communication.  Nothing herein contained shall
prevent a waiver of notice of meeting by directors.

Section 4.   At all meetings of the Board of Directors one-third of
- ----------
the entire Board of Directors as from time to time fixed under these
By-Laws shall constitute a quorum.

not the Chief Executive Officer, by the Chief Executive Officer, or by
these By-Laws, and if there is no Chairman, or in the absence or
disability of the Chairman, the President shall perform the duties of
that office.  When the Chairman of the Board is the Chief Executive

President may be performed by the Chief Executive Officer or in part
by such officer and in part by another officer or officers of the
Corporation, as specified by the Board.

Section 5.   The Vice Presidents, one or more of whom may be

the Corporation and shall be in charge of its books of account,
accounting records and accounting and internal auditing procedures.
He shall be responsible for the verification of all of the assets of
the Corporation and the preparation of all tax returns and other
financial reports to governmental agencies by the Corporation and
shall have such other duties and powers as shall be designated from
time to time by the Board of Directors or the Chairman of the Board.
The Controller shall be responsible to and shall report to the Board
of Directors, but in the ordinary conduct of the Corporation's
business shall be under the supervision of the Chairman of the Board
or such other officer as the Board of Directors shall designate.


Section 7.   The Treasurer, subject to the direction and supervision
- ----------
of such officer and to such limitations on his authority as the Board
of Directors may from time to time designate or prescribe, shall have

out and dispose of the funds and securities of the Corporation and in
general perform the duties customary to the office of Treasurer.

Section 8.   The Secretary shall keep the minutes of meetings of the
- ----------
Board of Directors and the minutes of the stockholders' meetings and
have the custody of the seal of the Corporation and affix and attest
the same to certificates of stock, contracts and other documents when
proper and appropriate.  He shall perform all of the other duties
usual to that office.

Section 9.   The Assistant Secretaries, Assistant Controllers and
- ----------
Assistant Treasurers shall perform such duties as may be assigned by
the Board of Directors.

- -----------
office until the next annual meeting of the Board of Directors and
until his successor is elected.  Any officer may be removed at any
time with or without cause by a vote of a majority of the members of
the Board of Directors.  A vacancy in any office caused by the death,
resignation or removal of the person elected thereto or because of the
creation of a new office or for any other reason, may be filled for
the unexpired portion of the term by election of the Board of
Directors at any meeting.  In case of the absence or disability, or
refusal to act of any officer of the Corporation, or for any other
reason that the Board of Directors shall deem sufficient, the Board
may delegate, for the time being, the powers and duties, or any of
them of such officer to any other officer or to any director.


                                Article IV
                                ----------

                               CAPITAL STOCK

Section 1.   Subscriptions to the capital stock must be paid to the
- ----------
Treasurer at such time or times, and in such installments as the Board
of Directors may by resolution require.

Section 2.   The certificate for shares of the Corporation shall be in
- ----------
such forms as shall be approved by the Board of Directors and shall be
signed by the Chairman of the Board or the President or a Vice
President and by the Treasurer or an Assistant Treasurer or the
Secretary or an Assistant Secretary, and shall be sealed with the seal
of the Corporation or a facsimile thereof.  The signatures of the
officers upon a certificate may be facsimiles if the certificate is
countersigned by a transfer agent or registered by a registrar other
than the Corporation itself or its employee.  In case any officer has
signed or whose facsimile signature has been placed upon a certificate
shall have ceased to be such officer before such certificate is
issued, it may be issued by the Corporation with the same effect as if
he were such officer at the date of issue.

Section 3.   Registration of transfers of shares shall be made upon
- ----------
the books of the Corporation by the registered holder in person or by
power of attorney, duly executed and filed with the Secretary or other

                                Article V
                                ---------

                          COMMITTEES OF THE BOARD

Section 1.  The Board of Directors may elect from among its members,
- ----------
by resolution adopted by two-thirds of the entire Board of Directors,
an Executive Committee consisting of the Chairman of the Board and
three or more other members of the Board.  From such Committee
members, the Board shall elect a Chairman of such Committee.

Section 2.   During the intervals between meetings of the Board of
- ----------
Directors, the Executive Committee shall, subject to any limitations
imposed by law or the Board of Directors, possess and may exercise all
the powers of the Board of Directors in the management and direction
of the Corporation in such manner as the Executive Committee shall
deem best for the interests of the Corporation, in all cases in which
specific directions shall not have been given by the Board of
Directors.

Section 3.   The Board of Directors may also elect from among its
- ----------
members, by resolutions adopted by a majority of the entire Board of
Directors, such other committee or committees as the Board of
Directors shall determine, each such committee to consist of at least
three members of the Board.  The Board shall elect a Chairman of each
such committee, shall fix the number of and elect the other members
thereof, and shall establish the duties and authority thereof, subject
to such limitations as may be required by law.

Section 4.   The Board of Directors shall fill any vacancies on any
- ----------
committee established under this Article, with the objective of
keeping the membership of each such committee full at all times.

Section 5.   All action by any committee of the Board of Directors
- ----------
shall be referred to the Board of Directors at its meeting next
succeeding such action, and shall be subject to revision or alteration
by the Board of Directors provided that no rights or acts of third
parties shall be affected by any such revision or alteration.  Subject
to such applicable resolutions as may be adopted by the Board, each
committee shall fix its own rules of procedure and shall meet where
and as provided in such rules, but in any case the presence of a
majority shall be necessary to constitute a quorum.

Section 6.  The Audit Committee of the Board of Directors shall be
- ----------
composed exclusively of independent, non-employee directors of the
Corporation.  For purposes of determining a director's independence,
the Board of Directors shall use the definition of "independent" as
proposed in February 1999 by the Blue Ribbon Committee on Improving
the Effectiveness of Corporate Audit Committees, which is repeated
below in its entirety.

       Members of the audit committee shall be considered
       independent if they have no relationship to the
       corporation that may interfere with the exercise of
       their independence from management and the corporation.
       Examples of such relationships include:

       - a director being employed by the corporation or any
       of its affiliates for the current year or any of the
       past five years;

       - a director accepting any compensation from the
       corporation or any of its affiliates other than
       compensation for board service or benefits under a tax-
       qualified retirement plan;

       - a director being a member of the immediate family of
       an individual who is, or has been in any of the past five
       years, employed by the corporation or any of its affiliates
       as an executive officer;

       - a director being a partner in, or a controlling
       shareholder or an executive officer of, any for-profit
       business organization to which the corporation made, or
       from which the corporation received, payments that are
       or have been significant to the corporation or business
       organization in any of the past five years;

       - a director being employed as an executive of another
       company where any of the corporation's executives serves
       on that company's compensation committee.

       A director who has one or more of these relationships
       may be appointed to the audit committee, if the board,
       under exceptional and limited circumstances, determines
       that membership on the committee by the individual is
       required by the best interests of the corporation and
       its shareholders, and the board discloses in the next
       annual proxy statement subsequent to the determination,
       the nature of the relationship and the reasons for that
       determination.



                                Article VI
                                ----------

                            MEETINGS BY CONSENT

Section 1.   Any action required or permitted to be taken by the Board
- ----------
of Directors or any committee thereof may be taken without a meeting
if all members of the Board or of the committee consent in writing to
the adoption of a resolution authorizing the action.  The resolution
and the written consents thereto by the members of the Board or
committee shall be filed with the minutes of the proceedings of the
Board of committee.

Section 2.   Any one or more members of the Board or any committee
- ----------
thereof may participate in a meeting of the Board or such committee by
means of a conference telephone or similar communications equipment
allowing all persons participating in the meeting to hear each other
at the same time.  Participation by such means shall constitute
presence in person at a meeting.


                                Article VII
                                -----------

                              INDEMNIFICATION

Section 1.   The Company shall, to the fullest extent permitted by
- ----------
applicable law, indemnify any person who is or was made, or threatened
to be made, a party to any action or proceeding, whether civil or
criminal, whether involving any actual or alleged breach of duty,
neglect or error, any accountability, or any actual or alleged
misstatement, misleading statement or other act or omission and
whether brought or threatened in any court or administrative or
legislative body or agency, including an action by or in the right of
the Company to procure a judgment in its favor and an action by or in
the right of any other corporation of any type or kind, domestic or
foreign, or any partnership, joint venture, trust, employee benefit
plan or other enterprise, which any director or officer of the Company
is serving or served in any capacity at the request of the Company, by
reason of the fact that he, his testator, or intestate, is or was a
director or officer of the Company, or is serving or served such other
corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise in any capacity, against judgments, fines, amounts
paid in settlement, and costs, charges and expenses, including
attorney's fees, or any appeal therein; provided, however, that no
indemnification shall be provided to any such person if a judgment or
other final adjudication adverse to the director or officer
establishes that (i) his acts were committed in bad faith or were the
result of active and deliberate dishonesty and, in either case, were
material to the cause of action so adjudicated, or (ii) he personally
gained in fact a financial profit or other advantage to which he was
not legally entitled.

Section 2.   The Company may indemnify any other person to whom the
- ----------
Company is permitted to provide indemnification or the advancement of
expenses by applicable law, whether pursuant to rights granted
pursuant to, or provided by, the New York Business Corporation Law or
other rights created by (i) a resolution of shareholders, (ii) a
resolution of directors, or (iii) an agreement providing for such
indemnification, it being expressly intended that these by-laws
authorize the creation of other rights in any such manner.

Section 3.   The Company shall, from time to time, reimburse or
- ----------
advance to any person referred to in Section 1 the funds necessary for
payment of expenses, including attorney's fees, incurred in connection
with any action or proceeding referred to in Section 1, upon receipt
of a written undertaking by or on behalf of such person to repay such
amount(s) if a judgment or other final adjudication adverse to the
director or officer establishes that (i) his acts were committed in
bad faith or were the result of active and deliberate dishonesty and,
in either case, were material to the cause of action so adjudicated,
or (ii) he personally gained in fact a financial profit or other
advantage to which he was not legally entitled.

Section 4.   Any director or officer of the Company serving (i)
- ----------
another corporation, of which a majority of the shares entitled to
vote in the election of its directors is held by the Company, or (ii)
any employee benefit plan of the Company or any corporation referred
to in clause (i), in any capacity shall be deemed to be doing so at
the request of the Company.

Section 5.   Any person entitled to be indemnified or to the
- ----------
reimbursement or advancement of expenses as a matter of right pursuant
to this Article may elect to have the right to indemnification (or
advancement of expenses) interpreted on the basis of the applicable
law in effect at the time of the occurrence of the event or events
giving rise to the action or proceeding, to the extent permitted by
law, or on the basis of the applicable law in effect at the time
indemnification is sought.

Section 6.   The right to be indemnified or to the reimbursement or
- ----------
advancement of expenses pursuant to this Article (i) is a contract
right pursuant to which the person entitled thereto may bring suit as
if the provisions hereof were set forth in a separate written contract
between the Company and the director or officer, (ii) is intended to
be retroactive and shall be available with respect to events occurring
prior to the adoption hereof, and (iii) shall continue to exist after
the rescission or restrictive modification hereof with respect to
events occurring prior thereto.

Section 7.   If a request to be indemnified or for the reimbursement
- ----------
or advancement of expenses pursuant hereto is not paid in full by the
Company within thirty days after a written claim has been received by
the Company, the claimant may at any time thereafter bring suit
against the Company to recover the unpaid amount of the Claim and, if
successful in whole or in part, the claimant shall be entitled also to
be paid the expenses of prosecuting such claim.  Neither the failure
of the Company (including its Board of Directors, independent legal
counsel, or its shareholders) to have made a determination prior to
the commencement of such action that indemnification of or
reimbursement or advancement of expenses to the claimant is proper in
the circumstances, nor an actual determination by the Company
(including its Board of Directors, independent legal counsel, or its
shareholders) that the claimant is not entitled to indemnification or
to the reimbursement or advancement of expenses, shall be a defense to
the action or create a presumption that the claimant is not so
entitled.

Section 8.   A person who has been successful, on the merits or
- ----------
otherwise, in the defense of a civil or criminal action or proceeding
of the character described in Section 1 shall be entitled to
indemnification only as provided in Sections 1 and 3, notwithstanding
any provision of the New York Business Corporation Law to the
contrary.

                                 AMENDMENTS

Section 1.   These By-Laws may be amended at any stockholders' meeting
- ----------
by a majority of the votes cast at such meeting by the holders of
shares entitled to vote thereon, represented either in person or by
proxy.

Section 2.   Subject to the limitations, if any, from time to time
- ----------
prescribed in By-Laws made by stockholders, the Board of Directors at
any regular or special meeting, by the vote of a majority of the
directors may make, alter, amend and repeal any By-Laws, but any
By-Laws made by the Board of Directors may be altered or repealed by
the stockholders.
