        Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1: Cost Associated with Unsolicited Offers to Acquire Company's Stock

The Company recorded charges of $4.6 million for obligations associated with
Thermo Electron Corporation's unsolicited tender offer.  These obligations
include investment banking fees, public relations expenses and legal fees. This
accrual resulted in a loss of $.05 per share for the third quarter ending
October 31, 1994. Without these charges, earnings per share for the quarter
would have been $.31 per share.


The estimated investment banking fees ($4.1 million) were derived by a formula
set forth in the contract between the Company and the investment banking firm.
Components of this formula include the number of shares outstanding and the
stock price at the time such fees become payable in full. The Company estimated
the fee using the closing stock price as of October 31, 1994, which was $26.13
per share and is considered to be the best estimate at that time. Until such
fees become payable in full, the Company will revise its estimate of such fees
quarterly based upon the closing stock price and any other circumstances
relevant to the contract as of the close of the reporting period. Legal fees
and public relations expenses will continue to be based upon the costs of
services actually rendered during the period.

Sales growth in the home care markets continues with revenues and orders up
20.6% and 15.6%, respectively, from Q3 last year and 15.7% and 19.2%,
respectively on a year-to-date basis. Two major clinical areas - home oxygen
therapy and the diagnosis and treatment of adult sleep disorders - contributed
to this growth. With respect to the first major clinical area, the Company
believes it is already the worldwide leader. Moreover, the Company has been
told by Homedco Group, Inc., one of the nation's leading providers of home
respiratory services, that Puritan-Bennett will be selected as one of its
endorsed vendors for home oxygen equipment. Homedco is in the process of
upgrading its oxygen therapy technology to achieve significantly greater
operational efficiencies. (While Homedco is one of the first to recognize and
act upon this opportunity, the same opportunity is available to virtually all
home oxygen therapy providers. A key element of the Company's homecare strategy
is to help all home oxygen suppliers recognize and act upon such opportunity.)
The Company also believes its home oxygen therapy product line is unusually
well suited to help home oxygen suppliers benefit from such opportunity.
This announcement is the result of Homedco's formal bid process, and will be
one of the largest
<PAGE>   6
purchases of oxygen therapy equipment in Homedco's history. The selection of
Puritan-Bennett as an endorsed vendor is expected to have a significant impact
on the home oxygen therapy portion of the Company's business over the next two
years. In addition, Homedco said it would work with the Company to adapt
Puritan-Bennett's CliniVision(R) Respiratory Care Management Information System
to its needs for managing its home care patients services. Heretofore,
CliniVision has been almost entirely a hospital market product.

With respect to the second major clinical area of its homecare product lines,
the Company expects its relatively young business of diagnosing and treating
adult sleep disorders to continue growing also. Recently published research
clearly indicates that millions of adults in the U.S. suffer chronically from
debilitating but treatable breathing disorders during sleep. The Company
believes the prevalence of such disorders is also widespread in most developed
nations. These disorders are only beginning to be recognized and understood by
the medical community and the general population. Consequently, only a small
fraction of people suffering from sleep disorders have been diagnosed and are
being treated today. Therefore, while the market for such sleep products has
grown rapidly in recent years, the Company believes that most of the market
growth lies ahead. With the late January 1994 acquisition of SEFAM S.A., the
Company believes it is among the top three in terms of worldwide market share.

While the Company believes it remains the worldwide leader in critical care
ventilation, hospital/physician sales have flattened as the U.S. hospital
market for the 7200(R) Series ventilator has declined; international demand
has continued to grow, however. The level of interest in CliniVision continues
to expand and revenues are growing as hospitals increasingly focus on this
system as a valuable solution to their cost-containment challenge and as the
Company continues to enhance the CliniVision system. More than 100 systems have
now been installed. In total, the Company expects hospital/physician market
revenues to be flat in FY 1995 and for moderate growth to resume in FY 1996 due
to CliniVision and five ventilator system-related new products/product
enhancements recently cleared by FDA for marketing in the U.S. and recently
introduced internationally.

The aviation portion of the Company's business is experiencing growth in
revenues and orders, up 24.1% and 26.6%, respectively, on a year-to-date basis.
Revenues were up 47.2% from third quarter levels last year and orders were up
60.5%. The overall increase in the Company's aviation business is due in large
part, although not entirely, to a growing interest in the offerings of Airborne
Closed Circuit Television (ACCTV (TM)). These closed circuit television systems
use video cameras to detect problems. Conditions such as fire, smoke and cargo
movement can be detected in all lighting conditions. Additionally, exterior
security as well as passenger entertainment systems are offered. Aside from
ACCTV, the overall tone of the aviation industry market is showing signs of
improvement from the depressed conditions of recent years.

The increase in foreign operations net sales and operating profit from Q3 1994
was primarily due to the addition of the SEFAM S.A. product line and a large
increase in sales in Germany. The German operation was in a start-up
environment during the comparable period of FY 1994. This explanation as well
as a Q2 FY 1994 restructuring charge of $9.0 million accounts for the dramatic
increase in the year-to-date FY 1995 net operating profit.

During the past decade, the Company's business profile has changed
substantially from being predominantly a supplier of life-support capital
equipment to the United States hospital market to becoming a major supplier to
the homecare market. Homecare has been, and is expected to continue to be, the
fastest growing part of the Company's business. Life-support products sold in
the U.S. market will likely represent a smaller share of the Company's business
in the future, a trend that may help lower the Company's risks.

In late January 1994, the Company finalized the previously announced
acquisition of SEFAM S.A., the leading European supplier of diagnostic and
therapeutic sleep disorder products, and its 80% owned Lit Dupont S.A.
subsidiary, which manufactures wheelchair products. Over the past five years,
the Company's home care business, which reached nearly $110 million in revenues
in FY 1994 has achieved a compound annual revenue growth rate of over 22%
worldwide - 31% internationally. The Company believes that the acquisition of
SEFAM will help such growth trends continue.

GROSS PROFIT

The gross profit percentage for Q3 1995 decreased 0.6% from Q3 1994 and 1.0% on
a year-to-date basis. Gross profit was adversely affected by the higher costs
associated with FDA Good Manufacturing Practice (GMP) compliance activities and
by the continued weakness of the U.S. hospital market. These effects were
partially offset by the results of operations of SEFAM, acquired late in FY94,
as well as the results of restructuring actions taken late in FY 1994.

SELLING AND ADMINISTRATIVE EXPENSES

Selling and administrative expenses for Q3 1995 remained relatively stable from
Q3 1994. An increase in such expenses resulting from the acquisition of SEFAM
S.A. and its 80% owned Lit Dupont S.A. subsidiary, in late FY 1994, and
increased GMP related compliance activities were offset by the results of
restructuring actions taken in late FY 1994.

RESEARCH AND DEVELOPMENT EXPENSES

Research and development expenses for the quarter and year-to-date have
decreased approximately 18% and 24%, respectively, over the prior comparable
periods. The decreases resulted entirely from the elimination of the
Intra-Arterial Blood Gas Monitoring product line. Research and development
continues across all remaining product lines at levels the Company considers
appropriate to provide long-term growth.

OTHER (INCOME) EXPENSE

Other income in the first nine months of FY 1995 increased over the comparable
period of FY 1994 by $1,654. The increase is entirely attributable to foreign
currency transaction gains in FY95 versus losses in FY94. These gains arose
from the weakening of the U.S.  Dollar, the Company's functional currency, in
the markets in which the Company is doing business. Since October 31, 1994, the
U.S.  dollar has strengthened considerably. If the U.S. dollar remains at
current levels, most of the foreign currency transaction gains realized in the
first nine months are expected to reverse in the fourth quarter.

INTEREST EXPENSE

Interest expense increased from Q3 1994 and YTD 1994 by $560 and $759,
respectively. The increase is due to higher levels of debt in FY 1995 as well
as an overall increase in the Company's average interest rate.


UNSOLICITED TAKEOVER OFFER

The Company recorded charges of $4.6 million for obligations associated with
Thermo Electron Corporation's unsolicited tender offer.  These obligations
include investment banking fees, public





<PAGE>   11
relations expenses and legal fees. This accrual resulted in a loss of $.05 per
share for the third quarter ending October 31, 1994.  Without the charge,
earnings per share for the quarter would have been $.31 per share. See Note 1
to the Condensed Consolidated Financial Statements.


RESTRUCTURING CHARGES

A number of market and regulatory developments converged to make FY 1994 a
particularly challenging one for the Company as a whole.  As a result, the
Company took a number of major actions in FY 1994 to reposition itself for the
future including:

        restructuring the hospital ventilator portion of its business;

        consolidating its aviation business to three facilities from four;

        closing its Boulder, Colorado facility and transferring the 
        manufacture of the portable ventilators made there to its ISO 
        (International Standards Organization) 9002 - certified facility in 
        the Republic of Ireland and

        planning the shutdown of the FOxS operation and offering it for sale.

As of October 31, 1994, approximately $3.9 million remained in accrued
liabilities representing expected severance, cancellation penalties, remaining
facility lease payments, FOxS customer refunds and other costs necessary to
complete the restructuring plan in an orderly and effective manner. This amount
is expected to be disbursed primarily in the fourth quarter of FY 1995 with
some carryover to the first and second quarters of FY 1996. No buyer was found
for the FOxS operation and the shutdown was completed in the third quarter.


PROVISION FOR INCOME TAXES

The Q3 1995 tax provision was affected by a year to date increase in the
annualized tax rate from 20% to 28% due to the interaction of the tax valuation
allowance discussed below and the shift, caused by the $4.6 million charge for
obligations associated with Thermo Electron Corporation's unsolicited tender
offer, in the proportion of earnings generated domestically, which are normally
taxed at the U.S. statutory rate of 35%, versus earnings generated
internationally, which are normally taxed at the lower foreign statutory rates
averaging 10%. The Q3 1994 tax rate was 32%. The year-to-date FY 1994 tax
benefit was 54% due primarily to a $9.0 million U.S. restructuring charge.

The Company has a net deferred tax benefit of $27.8 million partially offset by
a valuation allowance of $17.1 million as required by SFAS No. 109. The
realization of the deferred tax benefit depends on the Company's ability to
generate sufficient taxable income in the future. Approximately 80% of the
Company's total temporary differences are expected to reverse in the next two
years. As a result of the restructuring actions taken during FY 1994 and the
expected continuing growth in future profitability, the Company believes it is
well positioned to take advantage of this tax benefit in the future.






<PAGE>   12
If the Company achieves sufficient profitability to use all of the deferred tax
benefit, the valuation allowance will be reduced through a credit to expense.
If the Company is unable to generate taxable income in the future, increases in
the valuation allowance relative to the deferred tax benefit currently existing
will be required through a charge to expense.


FINANCIAL CONDITION


WORKING CAPITAL

The ratio of current assets to current liabilities was 2.2 at October 31, 1994,
up from 1.6 at January 31, 1994. Working capital increased, from $51.9 million
to $76.7 million. The primary reasons for the increase include a $12.1 million
decrease in notes payable as a result of the issuance of new long-term notes
late in Q2 1995 and an approximate $10.4 million decrease in other accrued
expenses, primarily accrued restructuring expenses that were paid in Q1, Q2 and
Q3 1995, offset by a $4.6 million accrual for expenses associated with an
unsolicited offer to acquire the Company's stock. In addition the Company's
investment in accounts receivable and inventory grew $9.3 million.


LIQUIDITY AND CAPITAL RESOURCES

Net cash and cash equivalents provided by operating activities decreased from
October 31, 1993 due to several factors. Net income of $7,328 for year-to-date
FY95 increased by approximately $12.4 million over the year-to-date loss for
FY94. There was a $9.0 million increase in year-to-date FY 1994 for accrued
restructuring charges versus no accrual in FY95. There was a $1.7 million
payout from the deferred compensation plan in Q1 1995 for which there was no
comparable event in FY 1994. The change in prepaid expenses and other current
assets reflects a sale of marketable equity securities ($2.2 million) for which
there was no comparable sale in FY 1994. The increase in accounts receivable is
a reflection of higher sales volume as well as an increase in the proportion of
non U.S. sales, which have a longer collection period than U.S. sales, to total
sales (28.0% as of year-to-date FY 1994 versus 33.8% as of year-to-date FY
1995).

Net cash and cash equivalents used in investing activities have decreased when
compared to year-to-date 1994. This decrease is due primarily to the
acquisition of Hoyer Medizintechnik; $6.6 million was paid in Q1 1994 and a
final payment of $2 million was paid in Q1 1995. An increase in proceeds from
the sale of capital assets was offset by an increase in capital expenditures.

Net cash and cash equivalents provided by financing activities have increased
when compared to year-to-date 1994. Short term notes payable have been reduced
by $12.1 million in year-to-date 1995 versus an $8.3 million increase in the
comparable FY 1994 period.  This reduction was offset by a $20 million increase
in long-term debt in year-to-date 1995. These events, combined with minimal
stock repurchases in year-to-date 1995 resulted in a generation of $2.8 million
from financing activities in year-to-date 1995 versus $.3 million in the same
period of the prior fiscal year.





<PAGE>   13
Long-term debt, excluding current maturities represents 33.9% of total capital
(long-term debt plus stockholder's equity) at October 31, 1994, and 26.4% at
January 31, 1994. At October 31, 1994, the Company had $35 million of unsecured
bank lines-of-credit available, $15.5 million of which was used.

U.S. HEALTH CARE SYSTEM CHANGES

While broad-scale health care system reform was a major initiative of the
Clinton Administration during its first two years, such broad reform does not
now appear imminent. At the same time, the U.S. health care system is
undergoing significant change in response to market forces. The principal
change involves increasing utilization of various forms of managed care.
Managed care trends are, in turn, causing hospitals to consolidate,
restructure, and otherwise slow their rate of spending growth. The Company
believes it is seeing the effects of such spending curtailment in its hospital
capital equipment products - principally the 7200 Series Ventilatory System.
The Company has not seen any significant adverse effects of managed care trends
on its homecare business and homecare may, in fact, be benefiting from such
trends due to its inherent cost-effectiveness relative to institutional care.
However, the new Congress, with its Republican majority, is likely to emphasize
further deficit reduction and there can be no assurance that homecare will not
be adversely affected by deficit reduction-driven legislative changes to the
Medicare and Medicaid programs.


SUPPLEMENTAL INFORMATION

In order to help stockholders better understand the economic dynamics and
potential of the Company's business, the Company decided to begin providing
supplemental information that sets forth its earnings before interest, taxes
and other unusual charges (EBITOC) and revenues in its two principal components
- - Puritan and Bennett. Unusual charges include any historical restructuring or
current Thermo Electron-related charges. The supplemental information also
excludes discontinued product lines. Supplemental pro-forma information dollars
are reported in thousands.

Puritan - Puritan includes the rapidly growing homecare product lines and
certain hospital/physician products such as medical gases and gas-related
equipment and spirometry. Aero Systems is also included because it shares one
of the larger manufacturing facilities with the Puritan Group and is relatively
small.

Puritan revenues for the first nine months grew to $159,391 from $136,263 on a
FY95 to FY94 comparison, up 17%. Third quarter FY95 revenues were up 23% to
$56,187 compared to $45,751 for third quarter of FY94. Puritan now accounts for
about two-thirds of the Company's total revenues. Puritan revenues for FY94
were also up from FY93, $184,239 versus $167,763. The average annual growth for
the five years ended January 31, 1994 was 15%. Within Puritan, homecare
products have grown at rates considerably above the overall Puritan average.

Puritan EBITOC was $16,306 (10% of revenue) and $18,493 (14% of revenue) for
the first nine months of FY95 and FY94, respectively.  For the third quarter of
this year, EBITOC was $5,995 (11% of revenue) versus $6,251 (14% of revenue) in
the third quarter FY94.  EBITOC was $22,939 (12% of revenue) and $24,740 (15%
of revenue) in FY94 and FY93, respectively.





<PAGE>   14
EBITOC has been higher in the recent past and, with continued revenue growth,
is expected to return to higher levels next fiscal year. The Company undertook
several major regulatory control and compliance initiatives in the latter part
of FY94 and during FY95.  These initiatives required considerable staffing and
other resource additions as well as manufacturing process modifications, which
temporarily increased costs faster than revenue growth. Puritan also
experienced some resulting short-run operating disruptions and inefficiencies,
which further increased costs. These operating disruptions have begun to
diminish, and the adverse profitability effects of the costs associated with
the considerable staffing and other resource additions in late FY94 and FY95
are expected to be covered by continuing rapid growth in Puritan revenues next
fiscal year coupled with much slower cost growth. This combination of revenue
growth and EBITOC growth as a percentage of Puritan revenues represents most of
the Company's expected profitability growth next fiscal year.

Bennett - Bennett includes the Company's critical care ventilator business - a
business that continues to represent an exceptional and long-standing customer
franchise on a global basis - as well as the CliniVision product line in the
U.S., and holter monitoring and portable ventilator product lines.

Since FY93, Bennett revenues have declined for several reasons including
difficult market conditions, particularly in the U.S.  hospital market,
discontinuance of certain older products and accessories as a result of
evolving regulatory standards, and the Company's withdrawal from the U.S.
portable ventilator market. In addition, Bennett has also undertaken major
regulatory control and compliance and new product development initiatives at
significant cost. Third quarter FY95 and FY94 revenues were $27,225 and
$28,838, respectively. For the first nine months of FY95 and FY94, revenues
were $88,422 and $90,361, respectively. FY94 revenues were $122,751 and FY93
revenues were $131,279.

On a quarter-to-quarter comparison, Bennett EBITOC was $456 for the third
quarter of FY95 versus a loss of $793 for the same period of FY94. EBITOC was
$2,620 and $2,718 for the first nine months of FY95 and FY94, respectively (3%
of revenues for both periods).  For the twelve month periods, FY94 EBITOC was
$14 compared to FY93 EBITOC of $11,803 (9% of revenue). Current and recent
EBITOC is not close to where the Company believes it should and will be. The
Company believes the recent poor profitability of Bennett will begin to reverse
itself and revenues and margins will increase as a result of continued cost
reductions as well as the continued growth of CliniVision and service revenue
and several other positive developments. These developments include five new
products/product enhancements recently cleared by FDA for marketing in the U.S.
and recently introduced internationally. In addition, other important new
products are being developed for introduction a little over a year from now.
Because of U.S. market conditions and these important new product development
initiatives, the Company's expectations for Bennett growth in revenues and
improvement in EBITOC as a percentage of revenues for next fiscal year (FY96)
are less than for Puritan. Bennett revenue and profitability growth
expectations are much higher after FY96, however.

The Company is encouraged by the continued strong growth of Puritan and
believes both Puritan and Bennett are well positioned to begin returning to
higher levels of profitability. Puritan is growing

rapidly and does not have so far to go to return to historical profitability
levels. Consequently, the Company expects Puritan's return to historical
profitability as a percentage of revenues to occur largely next fiscal year.
Bennett, on the other hand, has not been growing rapidly and has farther to go
to return to desired profitability levels. Key to doing so are additional new
products under development coupled with maintaining the Company's strong direct
sales and service distribution channels in North America and Europe, which are
capable of handling more volume. Such distribution channels enable these and
other new products to reach their full revenue and profitability potential.
Therefore, the Company expects it may take somewhat longer for Bennett
profitability as a percentage of revenues to reach desired levels.

The significant profitability growth expected next year from Puritan, the more
moderate but still important profitability growth expected next year from
Bennett, and the somewhat reduced interest expenses the Company expects to
result from gradually lower borrowing levels all combine to give the Company
confidence that its profitability for the fiscal year ending January 31, 1996,
will grow significantly from current fiscal year levels, which profitability
is, in turn, significantly higher than prior fiscal year levels. This does not
include unusual charges such as the change in control-type charges recently
incurred. The balance between revenue-led and cost reduction-led profitability
growth plans for fiscal year 1996 will be determined more precisely by the end
of this fiscal year.

                     Independent Accountants' Review Report

The Board of Directors
Puritan-Bennett Corporation

We have reviewed the condensed consolidated balance sheet of Puritan-Bennett
Corporation and subsidiaries as of October 31, 1994, the related condensed
consolidated statements of operations for the three-month and nine-month
periods ended October 31, 1994 and 1993, and the condensed consolidated
statements of cash flows for the nine-month periods ended October 31, 1994 and
1993 as presented in the accompanying exhibit. These financial statements are
the responsibility of the Company's management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, which will be
performed for the full year with the objective of expression of an opinion
regarding the financial statements taken as a whole. Accordingly, we do not
express such an opinion.

Based on our reviews, we are not aware of any material modifications that
should be made to the condensed consolidated financial statements referred to
above for them to be in conformity with generally accepted accounting
principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Puritan-Bennett Corporation and
subsidiaries as of January 31, 1994, and the related consolidated statement of
operations, stockholders' equity and cash flows for the year then ended, not
presented herein, and in our report dated March 7, 1994, we expressed an
unqualified opinion on those consolidated financial statements. During the year
ended January 31, 1994, the Company changed its method of accounting for income
taxes, postretirement benefits and postemployment benefits. In our opinion, the
information set forth in the condensed consolidated balance sheet as of January
31, 1994, as presented in the accompanying exhibit, is fairly stated, in all
material respects, in relation to the consolidated balance sheet from which it
has been derived.

                          PART II - OTHER INFORMATION


Item 1. Legal Proceedings.

On October 7, 1994, a purported class action complaint entitled Kenneth Steiner
v. Puritan-Bennett Corp., Burton A. Dole, Jr., C. Phillip Larson, Jr., Andre
F. Marion, Thomas A. McDonnell, Daniel C. Weary, Frank P. Wilton, C.A. No.
13790 (the "Steiner Complaint"), was filed against the Company and its
directors in the Court of Chancery of the State of Delaware in and for New
Castle County (the "Chancery Court"), alleging, among other things, that the
defendants have breached their fiduciary duties to the Company's stockholders
as a result of the defendants' adoption of a Rights Agreement dated on or about
May 17, 1989 and the directors' refusal to properly consider Thermo Electron
Corporation's initial proposal to acquire all outstanding shares at a price of
$21 per share (see Item 5. for additional information regarding the tender
offer). Among other things, the Steiner Complaint seeks an order directing the
Company's directors to carry out their fiduciary duties to the Company's
stockholders by cooperating fully with Thermo Electron Corporation or any
other entity or person having a bona fide interest in proposing any
extraordinary transactions with the Company, including a merger or acquisition
of the Company, as well as damages and costs. On October 24 and 28, 1994,
respectively, two purported class action complaints entitled Louise Kovacs v.
Puritan-Bennett Corp., et al., C.A. No. 13828 (the "Kovacs Complaint"), and
Charles Miller v. Puritan-Bennett Corporation, et al., C.A. No. 13839 (the
"Miller Complaint"), were filed against the Company and its directors in the
Chancery Court, alleging, among other things, that the defendants have breached
their fiduciary duties to the Company's stockholders as a result of the
defendants' refusal to properly consider Thermo Electron Corporation's
proposals to acquire all outstanding Shares. The material allegations and
prayers for relief contained in each of these complaints are substantially
similar to those contained in the Steiner Complaint filed earlier against the
Company and its directors.

The director defendants believe that they have fulfilled their fiduciary duties
to the Company and its shareholders and intend to continue to do so. The
Company and the director defendants intend to defend these actions vigorously.

On November 28, 1994, counsel to plaintiffs in each of the Steiner, Kovacs and
Miller actions filed an application in the Chancery Court requesting, among
other things, that the court schedule a hearing on plaintiffs' motion for a
preliminary injunction, which motion was filed on November 29, 1994.
Plaintiffs' motion for a preliminary injunction seeks an order (i) compelling
the defendants to meet with representatives of Thermo Electron Corporation to
discuss the terms of the tender offer and (ii) declaring null and void certain
provisions of the Executive Agreements, the Severance Agreements, the
Indemnification Agreements and the Company's employee benefit plans and
arrangements. On December 6, 1994, the Chancery Court issued a letter opinion
in which the Chancery Court declined to schedule a hearing on plaintiff's
motion. Citing the "substantial costs and disruption" to the defendants and the
public of an expedited preliminary injunction proceeding, the Chancery Court
found that the threatened "injury" alleged by the plaintiffs "is too
speculative to warrant intervention at this time."
<PAGE>   18
Item 5. Other Information.

On October 6, 1994, the Company received an unsolicited letter from Thermo
Electron Corporation proposing to acquire all of the outstanding common stock
of the Company in a merger transaction for $21 per share in cash. After
receiving an opinion from its financial advisor, Smith Barney Inc., on October
10, 1994, the Company rejected Thermo Electron Corporation's unsolicited
proposal to acquire the Company for $21 per share in cash as grossly inadequate
and not in the best interests of the Company and its shareholders other than
Thermo Electron Corporation. On October 12, 1994, Thermo Electron Corporation
raised its bid to $24 per share in cash. On October 25, 1994, Thermo Electron
Corporation launched a tender offer to acquire all of the outstanding shares of
the Company's common stock for $24.50 per share in cash expiring on November
22, 1994, subject to a number of conditions. On November 7, 1994, after
receiving an opinion from Smith Barney Inc., the Board of Directors of the
Company unanimously determined that the unsolicited tender offer from Thermo
Electron Corporation to acquire the Company for $24.50 per share in cash was
not in the best interests of the Company and its stockholders. Accordingly, the
Board recommended that stockholders reject the offer and not tender their
shares to Thermo Electron Corporation. On November 23, 1994, Thermo Electron
Corporation extended the tender offer to November 28, 1994 and then again to
December 8, 1994. On December 9, 1994, Thermo Electron Corporation terminated
its tender offer without purchasing any shares.

Mr. John H. Morrow
Executive Vice President
Puritan-Bennett Corporation
9401 Indian Creek Parkway
Overland Park, Kansas  66225

Dear Mr. Morrow:

         This supplemental letter agreement ("Supplemental Agreement") amends
and supplements the letter agreement dated June 9, 1994 (the "Agreement")
between you and Puritan-Bennett Corporation.  All definitions of terms in the
Agreement shall apply in this Supplemental Agreement.  As amended and
supplemented by this Supplemental Agreement, the Agreement shall remain in full
force and effect.

         1.      The benefits payable to you under Sections 3.1(a) and (b) of
the Agreement are hereby modified by replacing Sections 3.1(a) and (b) in their
entirety with the following:

         3.1     Rights upon Termination by Company other than for Cause, or by
                 Employee for Good Reason.  If the Company terminates your
                 employment other than for Cause prior to your Normal
                 Retirement Date, or if you terminate your employment for Good
                 Reason prior to your Normal Retirement Date, then the Company
                 shall have the following obligations to you:

                 (a)      During the applicable Continued Payment Period, the
                          Company shall make semi-monthly payments to you equal
                          to your semi-monthly base salary in effect
                          immediately prior to the Employment Termination Date
                          plus one twenty-fourth of the annual average of your
                          incentive bonus payments under the MIB Plan or any
                          successor thereto with respect to the three full (12
                          months) fiscal years immediately preceding the
                          Employment Termination Date (such annual average
                          being referred to herein as the "Average Annual
                          Incentive Payment"), such amounts to be computed
                          without regard to any reductions which may have
                          occurred in breach of this Agreement or following a
                          Change in Control.  Such payments shall be subject to
                          all required withholdings.  The Continued Payment
                          Period shall commence on the Employment Termination
                          Date and shall be a number of weeks determined by
                          adding (a) the greater of (i) four or (ii) two times
                          the number of years Employee has been an employee of
                          the Company (rounding up to the next full year and
                          excluding any intervening periods during which
                          Employee was not an employee of the Company), plus
                          (b) two times the number of $5,000 increments
                          (rounded up to the next whole $5,000 increment)
                          contained in the Employee's Annual Compensation (as
                          defined below); provided, that the Continued Payment
                          Period shall not

Mr. John H. Morrow

                          exceed three years.  "Annual Compensation" shall mean
                          the sum of (x) your annual base salary in effect
                          immediately prior to the Employment  Termination
                          Date, plus (y) the Average Annual Incentive Payment.

                 (b)      Any outstanding unvested options held by you to
                          purchase stock of the Company that have not otherwise
                          become exercisable under the terms of the Company's
                          stock option plans shall become fully vested and
                          exercisable.

         2.      If your employment is terminated under circumstances in which
                 you are entitled to receive payments under Section 3.1 of the
                 Agreement, and if you are not otherwise entitled to a bonus
                 payment with respect to the fiscal year in which your
                 employment is terminated, the Company will pay to you within
                 30 days after the Employment Termination Date, and subject to
                 required withholdings, a one-time bonus equal to the product
                 of (i) the fraction of a full year represented by the period
                 from the beginning of the fiscal year to the Employment
                 Termination Date, and (ii) the Average Annual Incentive
                 Payment.

         3.      If your employment is terminated under circumstances in which
                 you are entitled to receive payments under Section 3.1 of the
                 Agreement, then the Company will provide a benefit under the
                 Consolidated Omnibus Budget Reconciliation Act of 1986
                 ("COBRA") and Section 4980B of the Internal Revenue Code of
                 1986, as amended (the "Code"), as follows: the Company shall
                 pay the percentage of the cost of COBRA coverage with respect
                 to your coverage status (e.g., individual or family) in effect
                 immediately prior to the Employment Termination Date, which
                 percentage shall be the fraction (expressed as a percentage),
                 the numerator of which shall be the difference between (i) the
                 monthly cost of COBRA coverage for your coverage status in
                 effect immediately  prior to the Employment Termination Date
                 and (ii) your monthly contribution toward your coverage in
                 effect immediately prior to the Employment Termination Date,
                 and the denominator of which shall be the monthly cost of
                 COBRA coverage for your coverage status in effect immediately
                 prior to the Employment Termination Date.  All of such amounts
                 shall be determined as of the day immediately preceding the
                 termination of Employee's employment.  The insurance
                 continuation benefits paid for hereunder shall be deemed to be
                 part of your COBRA coverage.  Such benefits shall be in
                 addition to any other benefits relating to health or medical
                 care benefits that are available under the Company's policies
                 to you following termination of employment.

         4.      The severance benefits provided under the Agreement and this
                 Supplemental Agreement will be reduced by any severance
                 benefits to which you are entitled under the Company's
                 Severance Benefits policy for terminated employees, or any
                 other agreement between you and the Company for severance
                 benefits.  Except as provided in the immediately preceding
                 sentence, all of your rights and benefits, including those
                 under the Agreement and this Letter Agreement, shall remain in
                 full force and effect.  It is expressly agreed that payments
                 or benefits to you under the

                 Company's SERP or under any agreement with you relating to the
                 Company's SERP or any other retirement or pension arrangement
                 shall not be offset against or reduce in any way any payments
                 or benefits to which you are entitled under the Agreement or
                 under this Supplemental Agreement.

         5.      Section 5 of the Agreement is hereby replaced with the
                 following:

                 Non-Competition.  During your employment, you agree that you
                 will not directly or indirectly compete with the Company, or
                 engage in, or act as an officer, director, employee, or agent
                 of any person or entity that is engaged in, any business in
                 which the Company is engaged, without the written approval of
                 the CEO.  The foregoing shall not prohibit you from investing
                 in any securities of a corporation whose securities, or any of
                 them, are listed on a national securities exchange or traded
                 in the over-the-counter market so long as you shall own less
                 than 3% of the outstanding voting stock of such corporation.
                 If you are entitled to receive payments under Section 3.1(a),
                 then, as to any business in which the Company is engaged as of
                 the Employment Termination Date, you shall continue to be
                 bound by the provisions of this Section 5 during the
                 applicable Continued Payment Period.  If you violate the
                 provisions of this Section 5, then, in addition to any other
                 rights at law or in equity, the Company shall be entitled to
                 discontinue any payments otherwise due to you hereunder.

         6.      (a)      Anything in the Agreement or this Supplemental
                 Agreement to the contrary notwithstanding, in the event it
                 shall be determined that any payment or distribution by the
                 Company to or for the benefit of Employee (whether paid or
                 payable or distributed or distributable pursuant to the terms
                 of this Agreement or otherwise) (a "Payment") would be
                 nondeductible by the Company for Federal income tax purposes
                 because of Section 280G of the Code, then the aggregate
                 present value of amounts payable or distributable as severance
                 benefits hereunder shall be reduced to the Reduced Amount.
                 The "Reduced Amount" shall be an amount expressed in present
                 value which maximizes the aggregate present value of such
                 severance benefits without causing any Payment to be
                 nondeductible by the Company because of Section 280G of the
                 Code.  Anything to the contrary notwithstanding, if the
                 Reduced Amount is zero and it is determined further that any
                 Payment which is not part of the severance benefits payable
                 hereunder would nevertheless be nondeductible by the Company
                 for Federal income tax purposes because of Section 280G of the
                 Code, then the aggregate present value of Payments which are
                 not severance benefits under this Agreement shall also be
                 reduced (but not below zero) to an amount expressed in present
                 value which maximizes the aggregate present value of Payments
                 without causing any payment to be nondeductible by the Company
                 because of Section 280G of the Code.  For purposes of this
                 paragraph 6, present value shall be determined in accordance
                 with Section 280G(d)(4) of the Code.

                 (b)      All determinations required to be made under this
                 paragraph 6 shall be made by an accounting firm jointly
                 selected by you and the Company (the "Accounting Firm") and
                 paid by the Company, and which may be the Company's
                 independent auditors.  The Accounting Firm shall provide
                 detailed supporting calculations both to the Company and
                 Employee within 15 business days of the Date of Termination or
                 such earlier time as is requested by the Company and an
                 opinion to Employee that he or she has substantial authority
                 not to report any excise tax on his Federal income tax return
                 with respect to any Payments.  Any such determination by the
                 Accounting Firm shall be binding upon the Company and
                 Employee.  Employee shall determine which and how much of the
                 Payments, shall be eliminated or reduced consistent with the
                 requirements of this paragraph 6, provided that, if Employee
                 does not make such determination within ten business days of
                 the receipt of the calculations made by the Accounting Firm,
                 the Company shall elect which and how much of the Payments
                 shall be eliminated or reduced consistent with the
                 requirements of this paragraph 6 and shall notify Employee
                 promptly of such election; and provided further that any
                 Payments which do not constitute gross income to Employee
                 shall not be reduced or eliminated unless all other Payments
                 have first been eliminated.  Within five business days
                 thereafter, the Company shall pay to or distribute to or for
                 the benefit of Employee such amounts as are then due to
                 Employee under this Agreement.

                 (c)      As a result of the uncertainty in the application of
                 Section 280G of the Code at the time of the initial
                 determination by the Accounting Firm hereunder, it is possible
                 that Payments will have been made by the Company which should
                 not have been made ("Overpayment") or that Payments will not
                 have been made by the Company which could have been made
                 ("Underpayment"), in each case, consistent with the
                 calculations required to be made hereunder.  In the event that
                 the Accounting Firm, based upon the assertion of a deficiency
                 by the Internal Revenue Service against Employee or the
                 Company which the Accounting Firm believes has a high
                 probability of success, determines that an Overpayment has
                 been made, any such Overpayment paid or distributed by the
                 Company to or for the benefit of Employee shall be treated for
                 all purposes as a loan ab initio to Employee which Employee
                 shall repay to the Company together with interest at the
                 applicable federal rate provided for in Section 7872(f)(2) of
                 the Code; provided, however, that no such loan shall be deemed
                 to have been made and no amount shall be payable to the
                 Company if and to the extent such deemed loan and payment
                 would not either reduce the amount on which Employee is
                 subject to tax under Section 1 and Section 4999 of the Code or
                 generate a refund of such taxes.  In the event that the
                 Accounting Firm, based upon controlling precedent or other
                 substantial authority, determines that an Underpayment has
                 occurred, any such Underpayment shall be promptly paid by the
                 Company to or for the benefit of Employee together with
                 interest at 120% of the applicable federal rate provided for
                 in Section 7872(f)(2) of the Code, compounded semiannually.

         7.      Notwithstanding anything in the Agreement or this Supplemental
Agreement to the contrary, if after giving effect to the provisions of Section
6 of this Supplemental Agreement any

portion of any payments to you by the Company under the Agreement, this
Supplemental Agreement and any other present or future plan or program of the
Company or other present or future agreement between you and the Company would
not be deductible by the Company for Federal income tax purposes by reason of
application of Section 162(m) of the Code, then payment of that portion to you
shall be deferred until the earliest date upon which payment thereof can be
made to you without being non-deductible pursuant to Section 162(m) of the
Code.  In the event of such a deferral, the Company shall pay interest to you
on the amount deferred at 120% of the applicable federal rate provided for in
Section 7872(f)(2) of the Code, compounded semi-annually.

         8.      Miscellaneous.

         8.1.    No Assignment.  No benefit hereunder shall be subject to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrances or
charge, and any attempt to do so shall be void.

         8.2     Notices.  All notices hereunder shall be in writing, and shall
be delivered in person, by facsimile or by certified mail-return receipt
requested.  Notices shall be delivered as follows:

                             EXECUTIVE AGREEMENT

Mr. Robert L. Doyle
Senior Vice President, Marketing
Puritan-Bennett Corporation
9401 Indian Creek Parkway
P.O. Box 25905
Overland Park, KS  66225

Dear Mr. Doyle:

         This letter agreement restates and supersedes in its entirety the
letter agreement dated August 31, 1994 between you and Puritan-Bennett
Corporation (the "Company").  In view of your position as Senior Vice
President, Marketing of the Company and in consideration of your agreement to
continue serving in this or some other mutually agreeable capacity, the Board
of Directors (the "Board") of the Company has approved the commitment by the
Company to provide you ("Employee") with certain benefits during your
employment and in the event of termination of your employment for Good Reason,
if by you, and other than for Cause, if by the Company.  This letter agreement
(the "Agreement") establishes the terms and conditions of your continued
employment by the Company, including your rights to receive certain payments
and benefits during and after your employment by the Company.

         1.  Certain Definitions.

                 1.1      Cause.  "Cause" means (a) the Employee's willful
                          violation of any reasonable rule or direct order of
                          the Board or the Company's Chief Executive Officer
                          ("CEO"), which, after written notice to do so, the
                          Employee fails to make reasonable efforts to correct
                          within a reasonable time, or (b) conviction of a
                          crime, or entry of a plea of nolo contendere with
                          regard to a crime, involving actual moral turpitude
                          or dishonesty of or by the Employee, or (c) drug or
                          alcohol abuse on Company premises or at a Company
                          sponsored event, or (d) the Employee's material
                          violation of any provision of this Agreement, which,
                          after written notice to do so, the Employee fails to
                          make reasonable efforts to correct within a
                          reasonable time.  "Cause" shall not include any
                          matter other than those specified in (a) through (d)
                          above, and without limiting the generality of the
                          foregoing statement, Cause shall not include (x) any
                          charge or conviction of a crime, or entry of a plea
                          of nolo contendere with regard to a crime, under the
                          Federal Food, Drug, and Cosmetic Act, as amended, or
                          any successor statute thereto (the "Act"), or (y) the
                          imposition or attempt to impose upon the Employee, or
                          upon any operation, asset, product or activity of the
                          Company, of any other sanction or remedy under the
                          Act, including without limitation civil

                          money penalties, warning letters, injunctions,
                          repairs, replacements, refunds, recalls or seizures,
                          if the Employee acted in good faith and in a manner
                          which he reasonably believed to be in or not opposed
                          to the best interests of the Company.

                 1.2      Good Reason.  "Good Reason" means (a) breach by the
                          Company or any successor company of any of the
                          provisions of this Agreement not corrected within
                          ninety (90) days after written notice to the Company
                          thereof, or (b) any of the following if the same
                          shall occur within two years after a Change of
                          Control: (i) reduction of the Employee's base salary,
                          management bonus percentage or other compensation, as
                          in effect immediately prior to the Change of Control,
                          (ii) failure to continue in effect any medical,
                          dental, accident, or disability plan in which the
                          Employee is entitled to participate immediately prior
                          to the Change of Control and failure to provide plans
                          with substantially similar benefits (except that
                          employee contributions may be raised to the extent of
                          any cost increases imposed by third parties) or any
                          action by the Company which would adversely affect
                          the Employee's participation or reduce the Employee's
                          benefits under any of such plans, (iii) material
                          reduction in Employee's job responsibilities, (iv)
                          material reduction of Employee's title or position,
                          (v) Employee shall be requested to relocate to an
                          office outside of the greater Atlanta or Kansas City
                          metropolitan area, or (vi) failure or refusal of any
                          successor company to assume the Company's obligations
                          under this Agreement.

                 1.3      Change of Control.  A "Change of Control" shall be
                          deemed to have occurred at any of the following times:

                          1.3.1            Upon the acquisition (other than
                                           from the Company) by any person,
                                           entity or "group," within the
                                           meaning of Section 13(d)(3) or
                                           14(d)(2) of the Securities Exchange
                                           Act of 1934 (the "Exchange Act")
                                           (excluding, for this purpose, the
                                           Company or its affiliates, or any
                                           employee benefit plan of the Company
                                           or its affiliates which acquires
                                           beneficial ownership of voting
                                           securities of the Company) of
                                           beneficial ownership (within the
                                           meaning of Rule 13d-3 promulgated
                                           under the Exchange Act) of 50% or
                                           more of either the then outstanding
                                           shares of common stock of the
                                           Company or the Combined Voting Power
                                           of the Company's then outstanding
                                           voting securities.  "Combined Voting

                                           outstanding voting securities

         2.      Benefits and Duties During Employment; Termination of
                 Employment.

                 2.1      Base Salary.  Your current annual base salary is
                          $195,000, payable in 24 equal semi-monthly amounts,
                          subject to required withholdings.  Your base salary

                          base salary will not be reduced from the current
                          level or from any future, higher levels without your
                          written concurrence, unless such reduction is in
                          connection with your disability and in accordance
                          with the Company's established disability income
                          protection plan.

                          Bonus Plan ("MIB Plan").  Your target bonus
                          percentage under the MIB Plan will not be reduced
                          from the current level or from any future, higher
                          levels without your written concurrence, unless such
                          reduction is in connection with your disability and
                          in accordance with the Company's established
                          disability income protection plan.  The Company may
                          modify the MIB Plan in the future; provided that in
                          the event of any such modification, the Company will
                          use reasonable efforts to provide you with a bonus
                          opportunity under the modified plan that is
                          equivalent to your opportunity under the current MIB
                          Plan.

                          available to employees of the Company, and to the
                          special benefit programs in which you are currently
                          participating, or in which you are hereafter eligible
                          to participate.  These special benefits include but

                          Cause prior to your Normal Retirement Date, or if you
                          terminate your employment for Good Reason prior to
                          your Normal Retirement Date, then the Company shall
                          have the following obligations to you:

                          (a)     (i) If such termination occurs within two
                          years after a Change of Control, then within 30 days
                          following the Employment Termination Date, the
                          Company shall pay to you in a lump sum the present
                          value, determined as of the Employment Termination
                          Date, of the amounts that you would have been paid by
                          the Company if, during the applicable Continued
                          Payment Period, the Company were to make equal
                          semi-monthly payments to you equal to your
                          semi-monthly base salary in effect immediately prior
                          to the Employment Termination Date plus one
                          twenty-fourth of the annual average of your incentive
                          bonus payments under the MIB Plan or any successor
                          thereto with respect to the three full (12 months)
                          fiscal years immediately preceding the Employment
                          Termination Date (such annual average being referred
                          to herein as the "Average Annual Incentive Payment"),
                          such amounts to be computed without regard to any
                          reductions which may have occurred in breach of this
                          Agreement or following a Change in Control.  Such
                          payment shall be subject to all required
                          withholdings.  The Continued Payment Period shall
                          commence on the Employment Termination Date, and
                          shall be a number of weeks determined by adding (a)
                          the greater of (i) four or (ii) two times the number
                          of years Employee has been an employee of the Company

                          intervening periods during which Employee was not an
                          employee of the Company), plus (b) two times the
                          number of $5,000 increments (rounded up to the next
                          whole $5,000 increment) contained in the Employee's
                          Annual Compensation (as defined below), provided,
                          that the Continued Payment Period shall not exceed 3
                          years.  "Annual Compensation" shall mean the sum of
                          (x) your annual base salary in the effect immediately
                          prior to the Employment Termination Date, plus (y)
                          the Average Annual Incentive Payment.  Present value
                          shall be determined using a discount rate equal to
                          the Most Applicable Treasury Security Rate compounded
                          annually, if the Applicable Treasury Security is a
                          Treasury Bill, and semiannually, if the Applicable
                          Treasury Security is a Treasury Note.  The "Most
                          Applicable Treasury Security Rate" shall be the
                          yield-to- maturity of the Applicable Treasury
                          Security with a remaining term equal to one-half of
                          the Continued Payment Period, as quoted in the
                          edition of the Wall Street Journal first published
                          after the Employment Termination Date.  The
                          "Applicable Treasury Security" shall mean a Treasury
                          Bill if the Continued Payment Period is two years or
                          less; and shall mean a Treasury Note if the Continued
                          Payment Period is greater than two years.

                                  (ii)   If such termination occurs
                          at any time other than within two years after a
                          Change of Control, then, during the applicable
                          Continued Payment Period, the Company shall make
                          semi-monthly payments to you equal to your
                          semi-monthly base salary in effect immediately prior
                          to the Employment Termination Date plus one
                          twenty-fourth of the Average Annual Incentive
                          Payment, such amounts to be computed without regard
                          to any reductions which may have occurred in breach
                          of this Agreement.  Such payments shall be subject to
                          all required withholdings.

                          (b)     Any outstanding unvested options held by you
                          to purchase stock of the Company which have not
                          otherwise become exercisable under the terms of the
                          Company's stock option plans, shall become fully
                          vested and exercisable.

                          (c)     If your employment is terminated under
                          circumstances in which you are entitled to receive
                          payments under Section 3.1(a) above, and if you are
                          not otherwise entitled to a bonus payment with
                          respect to the fiscal year in which your employment
                          is terminated, the Company will pay to you within 30
                          days after the Employment Termination Date, and
                          subject to required withholdings, a one-time bonus
                          equal to the product

                          of (i) the fraction of a full year represented by the
                          period from the beginning of the fiscal year to the
                          Employment Termination Date, and (ii) the Average
                          Annual Incentive Payment.

                          (d)     As soon as practical following the Employment
                          Termination Date, the Company shall pay to you the
                          market value, as of close of business on the
                          Employment Termination Date, of any unvested
                          restricted stock awarded to you, subject to required
                          withholdings.

                 3.2      Death Benefits.  If you are terminated by the Company
                          other than for Cause or terminate your employment for
                          Good Reason, and thereafter you die during the
                          applicable Continued Payment Period, the Company
                          shall be obligated to pay to your spouse, if
                          surviving, and otherwise to your estate, the amounts
                          to which you would have been entitled under Section
                          3.1 had you survived.

                 3.3      No Obligation To Mitigate.  You shall not be required
                          to mitigate damages or the amount of any payment
                          provided for under this Agreement by seeking other
                          employment or otherwise, nor shall the amount of any
                          payment provided for under this Agreement be reduced
                          by any compensation earned by you as the result of
                          employment by another employer after the Employment
                          Termination Date, or otherwise.

                 3.4      COBRA Benefits.  If your employment is terminated
                          without cause by the Company, or for Good Reason by
                          you, then the Company will provide a benefit under
                          the Consolidated Omnibus Budget Reconciliation Act of
                          1986 ("COBRA") and Section 4980B of the Internal
                          Revenue Code of 1986, as amended (the "Code"), as
                          follows:  the Company shall pay the percentage of the
                          cost of COBRA coverage with respect to your coverage
                          status (e.g., individual or family coverage) in
                          effect immediately prior to the Employment
                          Termination Date, which percentage shall be the
                          fraction (expressed as a percentage), the numerator
                          of which shall be the difference between (i) the
                          monthly cost of COBRA coverage for your coverage
                          status in effect immediately prior to the Employment
                          Termination Date and (ii) your monthly contribution
                          toward your coverage in effect immediately prior to
                          the Employment Termination Date, and the denominator
                          of which shall be the monthly cost of COBRA coverage
                          for your coverage status in effect immediately prior
                          to the Employment Termination Date.  All of such
                          amounts shall be determined as of the day immediately
                          preceding the termination of Employee's employment.
                          The insurance continuation benefits paid for
                          hereunder shall be deemed to be part of Employee's
                          COBRA coverage.

                          Such benefits shall be in addition to any other
                          benefits relating to health or medical care benefits
                          that are available under the Company's policies to
                          Employee following termination of employment.

                 3.5      Other Rights.  The severance benefits provided
                          hereunder will be reduced by any severance benefits
                          to which you are entitled under the Company's
                          Severance Benefits policy for terminated employees,
                          or any other agreement between you and the Company
                          for severance benefits.  Except as provided in the
                          immediately preceding sentence, the provisions of
                          this Agreement, and any payment provided for
                          hereunder, shall not reduce any amounts otherwise
                          payable, or in any way diminish your existing rights
                          or rights which would accrue solely as a result of
                          the passage of time, under any benefit or incentive
                          plan, employment agreement or other contract, plan or
                          arrangement.  As soon as practical following the
                          Employment Termination Date, you will receive a cash
                          payment for the value of your earned but unused
                          vacation time as of the Employment Termination Date
                          in accordance with then current Company Policy.

         4.      Successor To Company.  The Company shall require any successor
                 or assignee, whether direct or indirect, by purchase, merger,
                 consolidation or otherwise to all or substantially all the
                 business or assets of the Company, expressly and
                 unconditionally to assume and agree to perform the Company's
                 obligations under this Agreement, in the same manner and to
                 the same extent that the Company would be required to perform
                 if no such succession or assignment had taken place.  In such
                 event, the term "Company," as used in this Agreement, shall
                 mean the Company and any successor or assignee to the business
                 or assets which by reason hereof becomes bound by the terms
                 and provisions of this Agreement.

         5.      Non-Competition.  During your employment, you agree that you
                 will not directly or indirectly compete with the Company, or
                 engage in, or act as an officer, director, employee, or agent
                 of any person or entity that is engaged in, any business in
                 which the Company is engaged, without the written approval of
                 the CEO.  The foregoing shall not prohibit you from investing
                 in any securities of a corporation whose securities, or any of
                 them, are listed on a national securities exchange or traded
                 in the over-the-counter market so long as you shall own less
                 than 3% of the outstanding voting stock of such corporation.
                 If you are receiving payments under Section 3.1(a)(ii), then,
                 as to any business in which the Company is engaged as of the
                 Employment Termination Date, you shall continue to be bound by
                 the provisions of this Section 5 during the applicable
                 Continued Payment Period.

         6.      Confidentiality.  During your employment and at all times
                 thereafter, you will not divulge to anyone or use for your own
                 benefit or the benefit of any other person or entity any
                 information concerning the Company, its businesses,
                 operations, products, plans, employees, or otherwise,
                 including without limitation trade secrets and other
                 proprietary information, except for information that has been
                 published by or with the consent of the Company and is as a
                 result thereof generally available to the public, or
                 information reasonably required by you for the preparation of
                 personal tax returns.

         7.      Reduction of Payments.

                 7.1      (a)     Anything in this Agreement to the contrary
                          notwithstanding, in the event it shall be determined
                          that any payment or distribution by the Company to or
                          for the benefit of Employee (whether paid or payable
                          or distributed or distributable pursuant to the terms
                          of this Agreement or otherwise) (a "Payment") would
                          be nondeductible by the Company for Federal income
                          tax purposes because of Section 280G of the Code,
                          then the aggregate present value of amounts payable
                          or distributable as severance benefits hereunder
                          shall be reduced to the Reduced Amount.  The "Reduced
                          Amount" shall be an amount expressed in present value
                          which maximizes the aggregate present value of such
                          severance benefits without causing any Payment to be
                          nondeductible by the Company because of Section 280G
                          of the Code.  Anything to the contrary
                          notwithstanding, if the Reduced Amount is zero and it
                          is determined further that any Payment which is not
                          part of the severance benefits payable hereunder
                          would nevertheless be nondeductible by the Company
                          for Federal income tax purposes because of Section
                          280G of the Code, then the aggregate present value of
                          Payments which are not severance benefits under this
                          Agreement shall also be reduced (but not below zero)
                          to an amount expressed in present value which
                          maximizes the aggregate present value of Payments
                          without causing any payment to be nondeductible by
                          the Company because of Section 280G of the Code.  For
                          purposes of this paragraph 7.1, present value shall
                          be determined in accordance with Section 280G(d)(4)
                          of the Code.

                          (b)     All determinations required to be made under
                          this paragraph 7.1 shall be made by an accounting
                          firm jointly selected by you and the Company (the
                          "Accounting Firm") and paid by the Company, and which
                          may be the Company's independent auditors.  The
                          Accounting Firm shall provide detailed supporting
                          calculations both to the Company and Employee within
                          15 business days of the Date of Termination or such
                          earlier time as is requested by the Company and an
                          opinion to Employee

                          that he or she has substantial authority not to
                          report any excise tax on his Federal income tax
                          return with respect to any Payments.  Any such
                          determination by the Accounting Firm shall be binding
                          upon the Company and Employee.  Employee shall
                          determine which and how much of the Payments, shall
                          be eliminated or reduced consistent with the
                          requirements of this paragraph 7.1, provided that, if
                          Employee does not make such determination within ten
                          business days of the receipt of the calculations made
                          by the Accounting Firm, the Company shall elect which
                          and how much of the Payments shall be eliminated or
                          reduced consistent with the requirements of this
                          paragraph 7.1 and shall notify Employee promptly of
                          such election; and provided further that any Payments
                          which do not constitute gross income to Employee
                          shall not be reduced or eliminated unless all other
                          Payments have first been eliminated.  Within five
                          business days thereafter, the Company shall pay to or
                          distribute to or for the benefit of Employee such
                          amounts as are then due to Employee under this
                          Agreement.

                          (c)     As a result of the uncertainty in the
                          application of Section 280G of the Code at the time
                          of the initial determination by the Accounting Firm
                          hereunder, it is possible that Payments will have
                          been made by the Company which should not have been
                          made ("Overpayment") or that Payments will not have
                          been made by the Company which could have been made
                          ("Underpayment"), in each case, consistent with the
                          calculations required to be made hereunder.  In the
                          event that the Accounting Firm, based upon the
                          assertion of a deficiency by the Internal Revenue
                          Service against Employee or the Company which the
                          Accounting Firm believes has a high probability of
                          success, determines that an Overpayment has been
                          made, any such Overpayment paid or distributed by the
                          Company to or for the benefit of Employee shall be
                          treated for all purposes as a loan ab initio to
                          Employee which Employee shall repay to the Company
                          together with interest at the applicable federal rate
                          provided for in Section 7872(f)(2) of the Code;
                          provided, however, that no such loan shall be deemed
                          to have been made and no amount shall be payable to
                          the Company if and to the extent such deemed loan and
                          payment would not either reduce the amount on which
                          Employee is subject to tax under Section 1 and
                          Section 4999 of the Code or generate a refund of such
                          taxes.  In the event that the Accounting Firm, based
                          upon controlling precedent or other substantial
                          authority, determines that an Underpayment has
                          occurred, any such Underpayment shall be promptly
                          paid by the Company to or for the benefit of Employee
                          together with interest at 120% of the applicable

                          federal rate provided for in Section 7872(f)(2) of
                          the Code, compounded semiannually.

                 7.2      Notwithstanding anything in this Agreement to the
                          contrary, if after giving effect to the provisions of
                          Section 7.1 any portion of any payments to you by the
                          Company hereunder and any other present or future
                          plan or program of the Company or other present or
                          future agreement between you and the Company would
                          not be deductible by the Company for Federal income
                          tax purposes by reason of application of Section
                          162(m) of the Code, then payment of that portion to

Dear Mr. Jones:

         In view of your position as Senior Vice President, General Manager
Puritan Group of Puritan-Bennett Corporation (the "Company") and in
consideration of your agreement to continue serving in this or some other
mutually agreeable capacity, the Board of Directors (the "Board") of the
Company has approved the commitment by the Company to provide you ("Employee")
with certain benefits during your employment and in the event of termination of
your employment for Good Reason, if by you, and other than for Cause, if by the
Company.  This letter agreement (the "Agreement") establishes the terms and
conditions of your continued employment by the Company, including your rights
to receive certain payments and benefits during and after your employment by
the Company.

         1.  Certain Definitions.

                 1.1      Cause.  "Cause" means (a) the Employee's willful
                          violation of any reasonable rule or direct order of
                          the Board or the Company's Chief Executive Officer
                          ("CEO"), which, after written notice to do so, the
                          Employee fails to make reasonable efforts to correct
                          within a reasonable time, or (b) conviction of a
                          crime, or entry of a plea of nolo contendere with
                          regard to a crime, involving actual moral turpitude
                          or dishonesty of or by the Employee, or (c) drug or
                          alcohol abuse on Company premises or at a Company

                          violation of any provision of this Agreement, which,
                          after written notice to do so, the Employee fails to
                          make reasonable efforts to correct within a
                          reasonable time.  "Cause" shall not include any
                          matter other than those specified in (a) through (d)
                          above, and without limiting the generality of the
                          foregoing statement, Cause shall not include (x) any
                          charge or conviction of a crime, or entry of a plea

                          in good faith and in a manner which he reasonably
                          believed to be in or not opposed to the best

                          the Employee's participation or reduce the Employee's
                          benefits under any of such plans, (iii) material

                          written concurrence, unless such reduction is in
                          connection with your disability and in accordance
                          with the Company's established disability income

                          percentage under the MIB Plan will not be reduced
                          from the current level or from any future, higher
                          levels without your written concurrence, unless such
                          reduction is in connection with your disability and

                          the event of any such modification, the Company will
                          use reasonable efforts to provide you with a bonus
                          opportunity under the modified plan that is
                          equivalent to your opportunity under the current MIB

                          immediately preceding the Employment Termination Date
                          (such annual average being referred to herein as the
                          "Average Annual Incentive Payment"), such amounts to
                          be computed without regard to any reductions which
                          may have occurred in breach of this Agreement or
                          following a Change in Control.  Such payment shall be
                          subject to all required withholdings.  The Continued
                          Payment Period shall commence on the Employment
                          Termination Date, and shall be a number of weeks
                          determined by adding (a) the greater of (i) four or
                          (ii) two times the number of years Employee has been
                          an employee of the Company (rounding up to the next
                          full year and excluding any intervening periods
                          during which Employee was not an employee of the
                          Company), plus (b) two times the number of $5,000
                          increments (rounded up to the next whole $5,000
                          increment) contained in the Employee's Annual
                          Compensation (as defined below), provided, that the
                          Continued Payment Period shall not exceed 3 years.
                          "Annual Compensation" shall mean the sum of (x) your
                          annual base salary in the effect immediately prior to
                          the Employment Termination Date, plus (y) the Average
                          Annual Incentive Payment.  Present value shall be
                          determined using a discount rate equal to the Most
                          Applicable Treasury Security Rate compounded
                          annually, if the Applicable Treasury Security is a
                          Treasury Bill, and semiannually, if the Applicable
                          Treasury Security is a Treasury Note.  The "Most
                          Applicable Treasury Security Rate" shall be the
                          yield-to-maturity of the Applicable Treasury Security
                          with a remaining term equal to one-half of the
                          Continued Payment Period, as quoted in the edition of
                          the Wall Street Journal first published after the
                          Employment Termination Date.  The "Applicable
                          Treasury Security" shall mean a Treasury Bill if the
                          Continued Payment Period is two years or less; and
                          shall mean a Treasury note if the Continued Payment
                          Period is greater than two years.

                                  (ii)   If such termination occurs
                          at any time other than within two years after a
                          Change of Control, then, during the applicable
                          Continued Payment Period, the Company shall make
                          semi-monthly payments to you equal to your
                          semi-monthly base salary in effect immediately prior
                          to the Employment Termination Date plus one
                          twenty-fourth of the Average Annual Incentive
                          Payment, such amounts to be computed without regard
                          to any reductions which may have occurred in breach
                          of this Agreement.  Such payments shall be subject to
                          all required withholdings.

                          (b)     Any outstanding unvested options held by you
                          to purchase stock of the Company which have not
                          otherwise become exercisable under the

                          become fully vested and exercisable.

                          (c)     If your employment is terminated under
                          circumstances in which you are entitled to receive
                          payments under Section 3.1(a) above, and if you are
                          not otherwise entitled to a bonus payment with
                          respect to the fiscal year in which your employment
                          is terminated, the Company will pay to you within 30
                          days after the Employment Termination Date, and
                          subject to required withholdings, a one-time bonus
                          equal to the product of (i) the fraction of a full
                          year represented by the period from the beginning of
                          the fiscal year to the Employment Termination Date,
                          and (ii) the Average Annual Incentive Payment.

                          (d)     As soon as practical following the Employment
                          Termination Date, the Company shall pay to you the
                          market value, as of close of business on the
                          Employment Termination Date, of any unvested
                          restricted stock awarded to you, subject to required
                          withholdings.

                          applicable Continued Payment Period, the Company
                          shall be obligated to pay to your spouse, if
                          surviving, and otherwise to your estate, the amounts
                          to which you would have been entitled under Section
                          3.1 had you survived.

                 3.3      No Obligation To Mitigate.  You shall not be required
                          to mitigate damages or the amount of any payment
                          provided for under this Agreement by seeking other
                          employment or otherwise, nor shall the amount of any
                          payment provided for under this Agreement be reduced
                          by any compensation earned by you as the result of
                          employment by another employer after the Employment
                          Termination Date, or otherwise.

                          follows:  the Company shall pay the percentage of the
                          cost of COBRA coverage with respect to your coverage
                          status (e.g., individual or family coverage) in
                          effect immediately prior to the Employment
                          Termination Date, which percentage shall be the
                          fraction (expressed as a percentage), the numerator
                          of which shall be the difference between (i) the
                          monthly cost

                          of COBRA coverage for your coverage status in effect
                          immediately prior to the Employment Termination Date
                          and (ii) your monthly contribution toward your
                          coverage in effect immediately prior to the
                          Employment Termination Date, and the denominator of
                          which shall be the monthly cost of COBRA coverage for
                          your coverage status in effect immediately prior to
                          the Employment Termination Date.  All of such amounts
                          shall be determined as of the day immediately
                          preceding the termination of Employee's employment.
                          The insurance continuation benefits paid for
                          hereunder shall be deemed to be part of Employee's
                          COBRA coverage.  Such benefits shall be in addition
                          to any other benefits relating to health or medical
                          care benefits that are available under the Company's
                          policies to Employee following termination of
                          employment.

                 3.5      Other Rights.  The severance benefits provided
                          hereunder will be reduced by any severance benefits
                          to which you are entitled under the Company's
                          Severance Benefits policy for terminated employees,
                          or any other agreement between you and the Company
                          for severance benefits.  Except as provided in the
                          immediately preceding sentence, the provisions of
                          this Agreement, and any payment provided for
                          hereunder, shall not reduce any amounts otherwise
                          payable, or in any way diminish your existing rights
                          or rights which would accrue solely as a result of
                          the passage of time, under any benefit or incentive
                          plan, employment agreement or other contract, plan or
                          arrangement.  As soon as practical following the
                          Employment Termination Date, you will receive a cash
                          payment for the value of your earned but unused
                          vacation time as of the Employment Termination Date
                          in accordance with then current Company Policy.

         4.      Successor To Company.  The Company shall require any successor
                 or assignee, whether direct or indirect, by purchase, merger,
                 consolidation or otherwise to all or substantially all the
                 business or assets of the Company, expressly and
                 unconditionally to assume and agree to perform the Company's
                 obligations under this Agreement, in the same manner and to
                 the same extent that the Company would be required to perform
                 if no such succession or assignment had taken place.  In such
                 event, the term "Company," as used in this Agreement, shall
                 mean the Company and any successor or assignee to the business
                 or assets which by reason hereof becomes bound by the terms
                 and provisions of this Agreement.

         5.      Non-Competition.  During your employment, you agree that you
                 will not directly or indirectly compete with the Company, or
                 engage in, or act as an officer, director, employee, or agent
                 of any person or entity that is engaged in, any

                 business in which the Company is engaged, without the written
                 approval of the CEO.  The foregoing shall not prohibit you
                 from investing in any securities of a corporation whose
                 securities, or any of them, are listed on a national
                 securities exchange or traded in the over-the-counter market
                 so long as you shall own less than 3% of the outstanding
                 voting stock of such corporation.  If you are receiving
                 payments under Section 3.1(a)(ii), then, as to any business in
                 which the Company is engaged as of the Employment Termination
                 Date, you shall continue to be bound by the provisions of this
                 Section 5 during the applicable Continued Payment Period.

         6.      Confidentiality.  During your employment and at all times
                 thereafter, you will not divulge to anyone or use for your own
                 benefit or the benefit of any other person or entity any
                 information concerning the Company, its businesses,
                 operations, products, plans, employees, or otherwise,
                 including without limitation trade secrets and other
                 proprietary information, except for information that has been
                 published by or with the consent of the Company and is as a
                 result thereof generally available to the public, or
                 information reasonably required by you for the preparation of
                 personal tax returns.

         7.      Reduction of Payments.

                 7.1      (a)     Anything in this Agreement to the contrary
                          notwithstanding, in the event it shall be determined
                          that any payment or distribution by the Company to or
                          for the benefit of Employee (whether paid or payable
                          or distributed or distributable pursuant to the terms
                          of this Agreement or otherwise) (a "Payment") would
                          be nondeductible by the Company for Federal income
                          tax purposes because of Section 280G of the Code,
                          then the aggregate present value of amounts payable
                          or distributable as severance benefits hereunder
                          shall be reduced to the Reduced Amount.  The "Reduced
                          Amount" shall be an amount expressed in present value
                          which maximizes the aggregate present value of such
                          severance benefits without causing any Payment to be
                          nondeductible by the Company because of Section 280G
                          of the Code.  Anything to the contrary
                          notwithstanding, if the Reduced Amount is zero and it
                          is determined further that any Payment which is not
                          part of the severance benefits payable hereunder
                          would nevertheless be nondeductible by the Company
                          for Federal income tax purposes because of Section
                          280G of the Code, then the aggregate present value of
                          Payments which are not severance benefits under this
                          Agreement shall also be reduced (but not below zero)
                          to an amount expressed in present value which
                          maximizes the aggregate present value of Payments
                          without causing any payment to be nondeductible by
                          the Company because of Section 280G of the Code.

                          For purposes of this paragraph 7.1, present value
                          shall be determined in accordance with Section
                          280G(d)(4) of the Code.

                          (b)     All determinations required to be made under
                          this paragraph 7.1 shall be made by an accounting
                          firm jointly selected by you and the Company (the
                          "Accounting Firm") and paid by the Company, and which
                          may be the Company's independent auditors.  The
                          Accounting Firm shall provide detailed supporting
                          calculations both to the Company and Employee within
                          15 business days of the Date of Termination or such
                          earlier time as is requested by the Company and an
                          opinion to Employee that he or she has substantial
                          authority not to report any excise tax on his Federal
                          income tax return with respect to any Payments.  Any
                          such determination by the Accounting Firm shall be
                          binding upon the Company and Employee.  Employee
                          shall determine which and how much of the Payments,
                          shall be eliminated or reduced consistent with the
                          requirements of this paragraph 7.1, provided that, if
                          Employee does not make such determination within ten
                          business days of the receipt of the calculations made
                          by the Accounting Firm, the Company shall elect which
                          and how much of the Payments shall be eliminated or
                          reduced consistent with the requirements of this
                          paragraph 7.1 and shall notify Employee promptly of
                          such election; and provided further that any Payments
                          which do not constitute gross income to Employee
                          shall not be reduced or eliminated unless all other
                          Payments have first been eliminated.  Within five
                          business days thereafter, the Company shall pay to or
                          distribute to or for the benefit of Employee such
                          amounts as are then due to Employee under this
                          Agreement.

                          (c)     As a result of the uncertainty in the
                          application of Section 280G of the Code at the time
                          of the initial determination by the Company's
                          independent auditors hereunder, it is possible that
                          Payments will have been made by the Company which
                          should not have been made ("Overpayment") or that
                          Payments will not have been made by the Company which
                          could have been made ("Underpayment"), in each case,
                          consistent with the calculations required to be made
                          hereunder.  In the event that the Accounting Firm,
                          based upon the assertion of a deficiency by the
                          Internal Revenue Service against Employee or the
                          Company which the Accounting Firm believes has a high
                          probability of success, determines that an
                          Overpayment has been made, any such Overpayment paid
                          or distributed by the Company to or for the benefit
                          of Employee shall be treated for all purposes as a
                          loan ab initio to Employee which Employee shall repay
                          to the Company together with interest at the
                          applicable federal rate provided for in Section
                          7872(f)(2) of the Code;

                          provided, however, that no such loan shall be deemed
                          to have been made and no amount shall be payable to
                          the Company if and to the extent such deemed loan and
                          payment would not either reduce the amount on which
                          Employee is subject to tax under Section 1 and
                          Section 4999 of the Code or generate a refund of such
                          taxes.  In the event that the Accounting Firm, based
                          upon controlling precedent or other substantial
                          authority, determines that an Underpayment has
                          occurred, any such Underpayment shall be promptly
                          paid by the Company to or for the benefit of Employee
                          together with interest at 120% of the applicable
                          federal rate provided for in Section 7872(f)(2) of
                          the Code, compounded semiannually.

                 7.2      Notwithstanding anything in this Agreement to the
                          contrary, if after giving effect to the provisions of
                          Section 7.1 any portion of any payments to you by the
                          Company hereunder and any other present or future
                          plan or program of the Company or other present or
                          future agreement between you and the Company would
                          not be deductible by the Company for Federal income
                          tax purposes by reason of application of Section
                          162(m) of the Code, then payment of that portion to
                          you shall be deferred until the earliest date upon
                          which payment thereof can be made to you without
                          being non-deductible pursuant to Section 162(m) of
                          the Code.  In the event of such a deferral, the
                          Company shall pay interest to you on the amount
                          deferred at 120% of the applicable federal rate
                          provided for in Section 7872(f)(2) of the Code,
                          compounded semi-annually.

         8.      Miscellaneous.

                 8.1.     No Assignment.  No benefit hereunder shall be subject
                          to anticipation, alienation, sale, transfer,
                          assignment, pledge, encumbrances or charge, and any
                          attempt to do so shall be void.

                 8.2      Notices.  All notices hereunder shall be in writing,
                          and shall be delivered in person, by facsimile or by
                          certified mail-return receipt requested.  Notices
                          shall be delivered as follows:

                 8.3      Governing Law.  This Agreement shall be governed by

                          Company and Employee arising out of this Agreement,

letter agreement dated August 31, 1994 between you and Puritan-Bennett
Corporation (the "Company").  In view of your position as Senior Vice
President, General Manager Bennett Group of the Company and in consideration of
your agreement to continue serving in this or some other mutually agreeable
capacity, the Board of Directors (the "Board") of the Company has approved the
commitment by the Company to provide you ("Employee") with certain benefits
during your employment and in the event of termination of your employment for
Good Reason, if by you, and other than for Cause, if by the Company.  This
letter agreement (the "Agreement") establishes the terms and conditions of your
continued employment by the Company, including your rights to receive certain
payments and benefits during and after your employment by the Company.

                          violation of any reasonable rule or direct order of
                          the Board or the Company's Chief Executive Officer
                          ("CEO"), which, after written notice to do so, the
                          Employee fails to make reasonable efforts to correct
                          within a reasonable time, or (b) conviction of a
                          crime, or entry of a plea of nolo contendere with
                          regard to a crime, involving actual moral turpitude
                          or dishonesty of or by the Employee, or (c) drug or
                          alcohol abuse on Company premises or at a Company

                          violation of any provision of this Agreement, which,
                          after written notice to do so, the Employee fails to
                          make reasonable efforts to correct within a
                          reasonable time.  "Cause" shall not include any
                          matter other than those specified in (a) through (d)
                          above, and without limiting the generality of the

                          charge or conviction of a crime, or entry of a plea

                          in good faith and in a manner which he reasonably
                          believed to be in or not opposed to the best

                          company to assume the Company's obligations under

                          subject to required withholdings.  Your base salary
                          will be reviewed and may be adjusted annually.  Your
                          base salary will not be reduced from the current
                          level or from any future, higher levels without your
                          written concurrence, unless such reduction is in
                          connection with your disability and in accordance
                          with the Company's established disability income
                          protection plan.

                          Bonus Plan ("MIB Plan").  Your target bonus
                          percentage under the MIB Plan will not be reduced
                          from the current level or from any future, higher
                          levels without your written concurrence, unless such
                          reduction is in connection with your disability and
                          in accordance with the Company's established
                          disability income protection plan.  The Company may
                          modify the MIB Plan in the future; provided that in
                          the event of any such modification, the Company will
                          use reasonable efforts to provide you with a bonus
                          opportunity under the modified plan that is
                          equivalent to your opportunity under the current MIB
                          Plan.

                          supervision of the CEO.  You may devote a reasonable
                          amount of time to civic and community affairs but

                 2.5      Employment Termination.  Your employment with the

                          termination of your employment.

         3.      Rights upon Termination of Employment.

                 3.1      Rights upon Termination by Company other than for
                          Cause, or by Employee for Good Reason.  If the
                          Company terminates your employment other than for
                          Cause prior to your Normal Retirement Date, or if you
                          terminate your employment for Good Reason prior to
                          your Normal Retirement Date, then the Company shall
                          have the following obligations to you:

                          (a)     (i) If such termination occurs within two
                          years after a Change of Control, then within 30 days
                          following the Employment Termination Date, the
                          Company shall pay to you in a lump sum the present
                          value, determined as of the Employment Termination
                          Date, of the amounts that you would have been paid by
                          the Company if, during the applicable Continued
                          Payment Period, the Company were to make equal
                          semi-monthly payments to you equal to your
                          semi-monthly base salary in effect immediately prior
                          to the Employment Termination Date plus one
                          twenty-fourth of the annual average of your incentive
                          bonus payments under the MIB Plan or any successor
                          thereto with respect to the three full (12 months)
                          fiscal years immediately preceding the Employment
                          Termination Date (such annual average being referred
                          to herein as the "Average Annual Incentive Payment"
                          [provided, if you have not been employed by the
                          Company during all of the three full fiscal years
                          immediately preceding the Employment Termination
                          Date, then "Average Annual Incentive Payment" shall
                          mean the annualized average of the bonus payments
                          received by you, computed based on the actual period
                          of your employment with the Company during any full
                          fiscal year(s) of the Company with respect to which
                          you have received a bonus]), such amounts to be
                          computed without regard to any reductions which may

                          have occurred in breach of this Agreement or
                          following a Change in Control.  Such payment shall be
                          subject to all required withholdings.  The Continued
                          Payment Period shall commence on the Employment
                          Termination Date, and shall be a number of weeks
                          determined by adding (a) the greater of (i) four or
                          (ii) two times the number of years Employee has been
                          an employee of the Company (rounding up to the next
                          full year and excluding any intervening periods
                          during which Employee was not an employee of the
                          Company), plus (b) two times the number of $5,000
                          increments (rounded up to the next whole $5,000
                          increment) contained in the Employee's Annual
                          Compensation (as defined below), provided, that the
                          Continued Payment Period shall not exceed 2 years.
                          "Annual Compensation" shall mean the sum of (x) your
                          annual base salary in the effect immediately prior to
                          the Employment Termination Date, plus (y) the Average
                          Annual Incentive Payment.  Present value shall be
                          determined using a discount rate equal to the Most
                          Applicable Treasury Security Rate compounded
                          annually, if the Applicable Treasury Security is a
                          Treasury Bill, and semiannually, if the Applicable
                          Treasury Security is a Treasury Note.  The "Most
                          Applicable Treasury Security Rate" shall be the
                          yield-to-maturity of the Applicable Treasury Security
                          with a remaining term equal to one-half of the
                          Continued Payment Period, as quoted in the edition of
                          the Wall Street Journal first published after the
                          Employment Termination Date.  The "Applicable
                          Treasury Security" shall mean a Treasury Bill if the
                          Continued Payment Period is two years or less; and
                          shall mean a Treasury Note if the Continued Payment
                          Period is greater than two years.

                                  (ii)    If such termination occurs
                          at any time other than within two years after a
                          Change of Control, then, during the applicable
                          Continued Payment Period, the Company shall make
                          semi-monthly payments to you equal to your
                          semi-monthly base salary in effect immediately prior
                          to the Employment Termination Date plus one
                          twenty-fourth of the Average Annual Incentive
                          Payment, such amounts to be computed without regard
                          to any reductions which may have occurred in breach
                          of this Agreement.  Such payments shall be subject to
                          all required withholdings.

                          (b)     Any outstanding unvested options held by you
                          to purchase stock of the Company which have not
                          otherwise become exercisable under the terms of the
                          Company's stock option plans, shall become fully
                          vested and exercisable.

                          (c)     If your employment is terminated under
                          circumstances in which you are entitled to receive
                          payments under Section 3.1(a) above, and if

                          you are not otherwise entitled to a bonus payment
                          with respect to the fiscal year in which your
                          employment is terminated, the Company will pay to you
                          within 30 days after the Employment Termination Date,
                          and subject to required withholdings, a one-time
                          bonus equal to the product of (i) the fraction of a
                          full year represented by the period from the
                          beginning of the fiscal year to the Employment
                          Termination Date, and (ii) the Average Annual
                          Incentive Payment.

                          (d)     As soon as practical following the Employment
                          Termination Date, the Company shall pay to you the
                          market value, as of close of business on the
                          Employment Termination Date, of any unvested
                          restricted stock awarded to you, subject to required
                          withholdings.

                 3.2      Death Benefits.  If you are terminated by the Company
                          other than for Cause or terminate your employment for
                          Good Reason, and thereafter you die during the
                          applicable Continued Payment Period, the Company
                          shall be obligated to pay to your spouse, if
                          surviving, and otherwise to your estate, the amounts
                          to which you would have been entitled under Section
                          3.1 had you survived.

                 3.3      No Obligation To Mitigate.  You shall not be required
                          to mitigate damages or the amount of any payment
                          provided for under this Agreement by seeking other
                          employment or otherwise, nor shall the amount of any
                          payment provided for under this Agreement be reduced
                          by any compensation earned by you as the result of
                          employment by another employer after the Employment
                          Termination Date, or otherwise.

                 3.4      COBRA Benefits.  If your employment is terminated
                          without cause by the Company, or for Good Reason by
                          you, then the Company will provide a benefit under
                          the Consolidated Omnibus Budget Reconciliation Act of
                          1986 ("COBRA") and Section 4980B of the Internal
                          Revenue Code of 1986, as amended (the "Code"), as
                          follows:  the Company shall pay the percentage of the
                          cost of COBRA coverage with respect to your coverage
                          status (e.g., individual or family coverage) in
                          effect immediately prior to the Employment
                          Termination Date, which percentage shall be the
                          fraction (expressed as a percentage), the numerator
                          of which shall be the difference between (i) the
                          monthly cost of COBRA coverage for your coverage
                          status in effect immediately prior to the Employment

                          toward your coverage in effect immediately prior to
                          the Employment Termination Date, and the denominator
                          of which shall be the monthly cost of COBRA coverage
                          for your coverage status in effect immediately

                          prior to the Employment Termination Date.  All of
                          such amounts shall be determined as of the day
                          immediately preceding the termination of Employee's
                          employment.  The insurance continuation benefits paid
                          for hereunder shall be deemed to be part of
                          Employee's COBRA coverage.  Such benefits shall be in
                          addition to any other benefits relating to health or
                          medical care benefits that are available under the
                          Company's policies to Employee following termination
                          of employment.

                 3.5      Other Rights.  The severance benefits provided
                          hereunder will be reduced by any severance benefits
                          to which you are entitled under the Company's
                          Severance Benefits policy for terminated employees,
                          or any other agreement between you and the Company
                          for severance benefits.  Except as provided in the
                          immediately preceding sentence, the provisions of
                          this Agreement, and any payment provided for
                          hereunder, shall not reduce any amounts otherwise
                          payable, or in any way diminish your existing rights
                          or rights which would accrue solely as a result of
                          the passage of time, under any benefit or incentive
                          plan, employment agreement or other contract, plan or
                          arrangement.  As soon as practical following the
                          Employment Termination Date, you will receive a cash
                          payment for the value of your earned but unused
                          vacation time as of the Employment Termination Date
                          in accordance with then current Company Policy.

         4.      Successor To Company.  The Company shall require any successor
                 or assignee, whether direct or indirect, by purchase, merger,
                 consolidation or otherwise to all or substantially all the
                 business or assets of the Company, expressly and
                 unconditionally to assume and agree to perform the Company's
                 obligations under this Agreement, in the same manner and to
                 the same extent that the Company would be required to perform
                 if no such succession or assignment had taken place.  In such
                 event, the term "Company," as used in this Agreement, shall
                 mean the Company and any successor or assignee to the business
                 or assets which by reason hereof becomes bound by the terms
                 and provisions of this Agreement.

         5.      Non-Competition.  During your employment, you agree that you
                 will not directly or indirectly compete with the Company, or
                 engage in, or act as an officer, director, employee, or agent
                 of any person or entity that is engaged in, any business in
                 which the Company is engaged, without the written approval of
                 the CEO.  The foregoing shall not prohibit you from investing
                 in any securities of a corporation whose securities, or any of
                 them, are listed on a national securities exchange or traded
                 in the over-the-counter market so long as you shall own less
                 than 3% of the outstanding voting stock of such corporation.
                 If you are

                 receiving payments under Section 3.1(a)(ii), then, as to any
                 business in which the Company is engaged as of the Employment
                 Termination Date, you shall continue to be bound by the
                 provisions of this Section 5 during the applicable Continued
                 Payment Period.

         6.      Confidentiality.  During your employment and at all times
                 thereafter, you will not divulge to anyone or use for your own
                 benefit or the benefit of any other person or entity any
                 information concerning the Company, its businesses,
                 operations, products, plans, employees, or otherwise,
                 including without limitation trade secrets and other
                 proprietary information, except for information that has been
                 published by or with the consent of the Company and is as a
                 result thereof generally available to the public, or
                 information reasonably required by you for the preparation of
                 personal tax returns.

         7.      Reduction of Payments.

                 7.1      (a)     Anything in this Agreement to the contrary
                          notwithstanding, in the event it shall be determined
                          that any payment or distribution by the Company to or
                          for the benefit of Employee (whether paid or payable
                          or distributed or distributable pursuant to the terms
                          of this Agreement or otherwise) (a "Payment") would
                          be nondeductible by the Company for Federal income
                          tax purposes because of Section 280G of the Code,
                          then the aggregate present value of amounts payable
                          or distributable as severance benefits hereunder
                          shall be reduced to the Reduced Amount.  The "Reduced
                          Amount" shall be an amount expressed in present value
                          which maximizes the aggregate present value of such
                          severance benefits without causing any Payment to be
                          nondeductible by the Company because of Section 280G
                          of the Code.  Anything to the contrary
                          notwithstanding, if the Reduced Amount is zero and it
                          is determined further that any Payment which is not
                          part of the severance benefits payable hereunder
                          would nevertheless be nondeductible by the Company
                          for Federal income tax purposes because of Section
                          280G of the Code, then the aggregate present value of
                          Payments which are not severance benefits under this
                          Agreement shall also be reduced (but not below zero)
                          to an amount expressed in present value which
                          maximizes the aggregate present value of Payments
                          without causing any payment to be nondeductible by
                          the Company because of Section 280G of the Code.  For
                          purposes of this paragraph 7.1, present value shall
                          be determined in accordance with Section 280G(d)(4)
                          of the Code.

                          (b)     All determinations required to be made under
                          this paragraph 7.1 shall be made by an accounting
                          firm jointly selected by you and the

                          Company (the "Accounting Firm") and paid by the
                          Company, and which may be the Company's independent
                          auditors.  The Accounting Firm shall provide detailed
                          supporting calculations both to the Company and
                          Employee within 15 business days of the Date of
                          Termination or such earlier time as is requested by
                          the Company and an opinion to Employee that he or she
                          has substantial authority not to report any excise
                          tax on his Federal income tax return with respect to
                          any Payments.  Any such determination by the
                          Accounting Firm shall be binding upon the Company and
                          Employee.  Employee shall determine which and how
                          much of the Payments, shall be eliminated or reduced
                          consistent with the requirements of this paragraph
                          7.1, provided that, if Employee does not make such
                          determination within ten business days of the receipt
                          of the calculations made by the Accounting Firm, the
                          Company shall elect which and how much of the
                          Payments shall be eliminated or reduced consistent
                          with the requirements of this paragraph 7.1 and shall
                          notify Employee promptly of such election; and
                          provided further that any Payments which do not
                          constitute gross income to Employee shall not be
                          reduced or eliminated unless all other Payments have
                          first been eliminated.  Within five business days
                          thereafter, the Company shall pay to or distribute to
                          or for the benefit of Employee such amounts as are
                          then due to Employee under this Agreement.

                          (c)     As a result of the uncertainty in the
                          application of Section 280G of the Code at the time
                          of the initial determination by the Accounting Firm
                          hereunder, it is possible that Payments will have
                          been made by the Company which should not have been
                          made ("Overpayment") or that Payments will not have
                          been made by the Company which could have been made
                          ("Underpayment"), in each case, consistent with the
                          calculations required to be made hereunder.  In the
                          event that the Accounting Firm, based upon the
                          assertion of a deficiency by the Internal Revenue
                          Service against Employee or the Company which the
                          Accounting Firm believes has a high probability of
                          success, determines that an Overpayment has been
                          made, any such Overpayment paid or distributed by the
                          Company to or for the benefit of Employee shall be
                          treated for all purposes as a loan ab initio to
                          Employee which Employee shall repay to the Company
                          together with interest at the applicable federal rate
                          provided for in Section 7872(f)(2) of the Code;
                          provided, however, that no such loan shall be deemed
                          to have been made and no amount shall be payable to
                          the Company if and to the extent such deemed loan and
                          payment would not either reduce the amount on which
                          Employee is subject to tax under Section 1 and
                          Section 4999 of the Code or generate a refund of such
                          taxes.  In the event that the

                          Accounting Firm, based upon controlling precedent or
                          other substantial authority, determines that an
                          Underpayment has occurred, any such Underpayment
                          shall be promptly paid by the Company to or for the
                          benefit of Employee together with interest at 120% of
                          the applicable federal rate provided for in Section
                          7872(f)(2) of the Code, compounded semiannually.

                 7.2      Notwithstanding anything in this Agreement to the
                          contrary, if after giving effect to the provisions of
                          Section 7.1 any portion of any payments to you by the
                          Company hereunder and any other present or future
                          plan or program of the Company or other present or
                          future agreement between you and the Company would
                          not be deductible by the Company for Federal income
                          tax purposes by reason of application of Section
                          162(m) of the Code, then payment of that portion to
                          you shall be deferred until the earliest date upon
                          which payment thereof can be made to you without
                          being non-deductible pursuant to Section 162(m) of
                          the Code.  In the event of such a deferral, the
                          Company shall pay interest to you on the amount
                          deferred at 120% of the applicable federal rate
                          provided for in Section 7872(f)(2) of the Code,
                          compounded semi-annually.

         8.      Miscellaneous.

                 8.1.     No Assignment.  No benefit hereunder shall be subject
                          to anticipation, alienation, sale, transfer,
                          assignment, pledge, encumbrances or charge, and any
                          attempt to do so shall be void.

                 8.2      Notices.  All notices hereunder shall be in writing,

                          shall be delivered as follows:

                               November 7, 1994


Mr. David P. Niles
Vice President, Quality and Regulatory Affairs
Puritan-Bennett Corporation
9401 Indian Creek Parkway
P.O. Box 25905
Overland Park, KS  66225

Dear Mr. Niles:

        This letter agreement restates and supersedes in its entirety the
letter agreement dated August 31, 1994 between you and Puritan-Bennett
Corporation (the "Company").  In view of your position as Vice President,
Quality and Regulatory Affairs of the Company and in consideration of your
agreement to continue serving in this or some other mutually agreeable
capacity, the Board of Directors (the "Board") of the Company has approved the
commitment by the Company to provide you ("Employee") with certain benefits
during your employment and in the event of termination of your employment for
Good Reason, if by you, and other than for Cause, if by the Company.  This
letter agreement (the "Agreement") establishes the terms and conditions of your
continued employment by the Company, including your rights to receive certain
payments and benefits during and after your employment by the Company.

        1.  Certain Definitions.

                 1.1     Cause.  "Cause" means (a) the Employee's willful
                         violation of any reasonable rule or direct order of

        3.       Rights upon Termination of Employment.

                 3.1     Rights upon Termination by Company other than for
                         Cause, or by Employee for Good Reason.  If the Company
                         terminates your employment other than for Cause prior
                         to your Normal Retirement Date, or if you terminate
                         your employment for Good Reason prior to your Normal
                         Retirement Date, then the Company shall have the
                         following obligations to you:

                         (a)      (i) If such termination occurs within two
                         years after a Change of Control, then within 30 days
                         following the Employment Termination Date, the Company
                         shall pay to you in a lump sum the present value,
                         determined as of the Employment Termination Date, of
                         the amounts that you would have been paid by the
                         Company if, during the applicable Continued Payment
                         Period, the Company were to make equal semi-monthly
                         payments to you equal to your semi-monthly base salary
                         in effect immediately prior to the Employment
                         Termination Date plus one twenty-fourth of the annual
                         average of your incentive bonus payments under the MIB
                         Plan or any successor thereto with respect to the
                         three full (12 months) fiscal years immediately
                         preceding the Employment Termination Date (such annual
                         average being referred to herein as the "Average
                         Annual Incentive Payment"), such amounts to be
                         computed without regard to any reductions which may
                         have occurred in breach of this Agreement or following
                         a Change in Control.  Such payment shall be subject to
                         all required withholdings.  The Continued Payment
                         Period shall commence on the Employment Termination
                         Date, and shall be a number of weeks determined by
                         adding (a) the greater of (i) four or (ii) two times
                         the number of years Employee has been an employee of
                         the Company (rounding up to the next full year and
                         excluding any

                         intervening periods during which Employee was not an
                         employee of the Company), plus (b) two times the
                         number of $5,000 increments (rounded up to the next
                         whole $5,000 increment) contained in the Employee's
                         Annual Compensation (as defined below), provided, that
                         the Continued Payment Period shall not exceed 2 years.
                         "Annual Compensation" shall mean the sum of (x) your
                         annual base salary in the effect immediately prior to
                         the Employment Termination Date, plus (y) the Average
                         Annual Incentive Payment.  Present value shall be
                         determined using a discount rate equal to the Most
                         Applicable Treasury Security Rate compounded annually,
                         if the Applicable Treasury Security is a Treasury
                         Bill, and semiannually, if the Applicable Treasury
                         Security is a Treasury Note.  The "Most Applicable
                         Treasury Security Rate" shall be the yield-to-maturity
                         of the Applicable Treasury Security with a remaining
                         term equal to one-half of the Continued Payment
                         Period, as quoted in the edition of the Wall Street
                         Journal first published after the Employment
                         Termination Date.  The "Applicable Treasury Security"
                         shall mean a Treasury Bill if the Continued Payment
                         Period is two years or less; and shall mean a Treasury
                         Note if the Continued Payment Period is greater than
                         two years.

                                  (ii)             If such termination occurs
                         at any time other than within two years after a Change
                         of Control, then, during the applicable Continued
                         Payment Period, the Company shall make semi-monthly
                         payments to you equal to your semi-monthly base salary
                         in effect immediately prior to the Employment
                         Termination Date plus one twenty-fourth of the Average
                         Annual Incentive Payment, such amounts to be computed
                         without regard to any reductions which may have
                         occurred in breach of this Agreement.  Such payments
                         shall be subject to all required withholdings.

                         (b)      Any outstanding unvested options held by you
                         to purchase stock of the Company which have not
                         otherwise become exercisable under the terms of the
                         Company's stock option plans, shall become fully
                         vested and exercisable.

                         (c)      If your employment is terminated under
                         circumstances in which you are entitled to receive
                         payments under Section 3.1(a) above, and if you are
                         not otherwise entitled to a bonus payment with respect
                         to the fiscal year in which your employment is
                         terminated, the Company will pay to you within 30 days
                         after the Employment Termination Date, and subject to
                         required withholdings, a one-time bonus equal to the
                         product

                         of (i) the fraction of a full year represented by the
                         period from the beginning of the fiscal year to the
                         Employment Termination Date, and (ii) the Average
                         Annual Incentive Payment.

                         (d)      As soon as practical following the Employment
                         Termination Date, the Company shall pay to you the
                         market value, as of close of business on the
                         Employment Termination Date, of any unvested
                         restricted stock awarded to you, subject to required
                         withholdings.

                 3.2     Death Benefits.  If you are terminated by the Company
                         other than for Cause or terminate your employment for
                         Good Reason, and thereafter you die during the
                         applicable Continued Payment Period, the Company shall
                         be obligated to pay to your spouse, if surviving, and
                         otherwise to your estate, the amounts to which you
                         would have been entitled under Section 3.1 had you
                         survived.

                 3.3     No Obligation To Mitigate.  You shall not be required
                         to mitigate damages or the amount of any payment
                         provided for under this Agreement by seeking other
                         employment or otherwise, nor shall the amount of any
                         payment provided for under this Agreement be reduced
                         by any compensation earned by you as the result of
                         employment by another employer after the Employment
                         Termination Date, or otherwise.

                 3.4     COBRA Benefits.  If your employment is terminated
                         without cause by the Company, or for Good Reason by
                         you, then the Company will provide a benefit under the
                         Consolidated Omnibus Budget Reconciliation Act of 1986
                         ("COBRA") and Section 4980B of the Internal Revenue
                         Code of 1986, as amended (the "Code"), as follows:
                         the Company shall pay the percentage of the cost of
                         COBRA coverage with respect to your coverage status
                         (e.g., individual or family coverage) in effect
                         immediately prior to the Employment Termination Date,
                         which percentage shall be the fraction (expressed as a
                         percentage), the numerator of which shall be the
                         difference between (i) the monthly cost of COBRA
                         coverage for your coverage status in effect
                         immediately prior to the Employment Termination Date
                         and (ii) your monthly contribution toward your
                         coverage in effect immediately prior to the Employment
                         Termination Date, and the denominator of which shall
                         be the monthly cost of COBRA coverage for your
                         coverage status in effect immediately prior to the
                         Employment Termination Date.  All of such amounts
                         shall be determined as of the day immediately
                         preceding the termination of Employee's employment.
                         The insurance continuation benefits paid for hereunder
                         shall be deemed to be part of Employee's COBRA
                         coverage.

                         Such benefits shall be in addition to any other
                         benefits relating to health or medical care benefits
                         that are available under the Company's policies to
                         Employee following termination of employment.

                 3.5     Other Rights.  The severance benefits provided
                         hereunder will be reduced by any severance benefits to
                         which you are entitled under the Company's Severance
                         Benefits policy for terminated employees, or any other
                         agreement between you and the Company for severance
                         benefits.  Except as provided in the immediately
                         preceding sentence, the provisions of this Agreement,
                         and any payment provided for hereunder, shall not
                         reduce any amounts otherwise payable, or in any way
                         diminish your existing rights or rights which would
                         accrue solely as a result of the passage of time,
                         under any benefit or incentive plan, employment
                         agreement or other contract, plan or arrangement.  As
                         soon as practical following the Employment Termination
                         Date, you will receive a cash payment for the value of
                         your earned but unused vacation time as of the
                         Employment Termination Date in accordance with then
                         current Company Policy.

        4.       Successor To Company.  The Company shall require any successor
                 or assignee, whether direct or indirect, by purchase, merger,
                 consolidation or otherwise to all or substantially all the
                 business or assets of the Company, expressly and
                 unconditionally to assume and agree to perform the Company's
                 obligations under this Agreement, in the same manner and to
                 the same extent that the Company would be required to perform
                 if no such succession or assignment had taken place.  In such
                 event, the term "Company," as used in this Agreement, shall
                 mean the Company and any successor or assignee to the business
                 or assets which by reason hereof becomes bound by the terms
                 and provisions of this Agreement.

        5.       Non-Competition.  During your employment, you agree that you
                 will not directly or indirectly compete with the Company, or
                 engage in, or act as an officer, director, employee, or agent
                 of any person or entity that is engaged in, any business in
                 which the Company is engaged, without the written approval of
                 the CEO.  The foregoing shall not prohibit you from investing
                 in any securities of a corporation whose securities, or any of
                 them, are listed on a national securities exchange or traded
                 in the over-the-counter market so long as you shall own less
                 than 3% of the outstanding voting stock of such corporation.
                 If you are receiving payments under Section 3.1(a)(ii), then,
                 as to any business in which the Company is engaged as of the
                 Employment Termination Date, you shall continue to be bound by
                 the provisions of this Section 5 during the applicable
                 Continued Payment Period.

        6.       Confidentiality.  During your employment and at all times
                 thereafter, you will not divulge to anyone or use for your own
                 benefit or the benefit of any other person or entity any
                 information concerning the Company, its businesses,
                 operations, products, plans, employees, or otherwise,
                 including without limitation trade secrets and other
                 proprietary information, except for information that has been
                 published by or with the consent of the Company and is as a
                 result thereof generally available to the public, or
                 information reasonably required by you for the preparation of
                 personal tax returns.

        7.       Reduction of Payments.

                 7.1     (a)      Anything in this Agreement to the contrary
                         notwithstanding, in the event it shall be determined
                         that any payment or distribution by the Company to or
                         for the benefit of Employee (whether paid or payable
                         or distributed or distributable pursuant to the terms
                         of this Agreement or otherwise) (a "Payment") would be
                         nondeductible by the Company for Federal income tax
                         purposes because of Section 280G of the Code, then the
                         aggregate present value of amounts payable or
                         distributable as severance benefits hereunder shall be
                         reduced to the Reduced Amount.  The "Reduced Amount"
                         shall be an amount expressed in present value which
                         maximizes the aggregate present value of such
                         severance benefits without causing any Payment to be
                         nondeductible by the Company because of Section 280G
                         of the Code.  Anything to the contrary
                         notwithstanding, if the Reduced Amount is zero and it
                         is determined further that any Payment which is not
                         part of the severance benefits payable hereunder would
                         nevertheless be nondeductible by the Company for
                         Federal income tax purposes because of Section 280G of
                         the Code, then the aggregate present value of Payments
                         which are not severance benefits under this Agreement
                         shall also be reduced (but not below zero) to an
                         amount expressed in present value which maximizes the
                         aggregate present value of Payments without causing
                         any payment to be nondeductible by the Company because
                         of Section 280G of the Code.  For purposes of this
                         paragraph 7.1, present value shall be determined in
                         accordance with Section 280G(d)(4) of the Code.

                         (b)      All determinations required to be made under
                         this paragraph 7.1 shall be made by an accounting firm
                         jointly selected by you and the Company (the
                         "Accounting Firm") and paid by the Company, and which

                         Accounting Firm shall provide detailed supporting

                         earlier time as is requested by the Company and an

                         that he or she has substantial authority not to report
                         any excise tax on his Federal income tax return with
                         respect to any Payments.  Any such determination by
                         the Accounting Firm shall be binding upon the Company
                         and Employee.  Employee shall determine which and how
                         much of the Payments, shall be eliminated or reduced
                         consistent with the requirements of this paragraph
                         7.1, provided that, if Employee does not make such
                         determination within ten business days of the receipt
                         of the calculations made by the Accounting Firm, the
                         Company shall elect which and how much of the Payments
                         shall be eliminated or reduced consistent with the
                         requirements of this paragraph 7.1 and shall notify
                         Employee promptly of such election; and provided
                         further that any Payments which do not constitute
                         gross income to Employee shall not be reduced or
                         eliminated unless all other Payments have first been
                         eliminated.  Within five business days thereafter, the
                         Company shall pay to or distribute to or for the
                         benefit of Employee such amounts as are then due to
                         Employee under this Agreement.

                         (c)      As a result of the uncertainty in the
                         application of Section 280G of the Code at the time of
                         the initial determination by the Accounting Firm
                         hereunder, it is possible that Payments will have been
                         made by the Company which should not have been made
                         ("Overpayment") or that Payments will not have been
                         made by the Company which could have been made
                         ("Underpayment"), in each case, consistent with the
                         calculations required to be made hereunder.  In the
                         event that the Accounting Firm, based upon the
                         assertion of a deficiency by the Internal Revenue
                         Service against Employee or the Company which the
                         Accounting Firm believes has a high probability of
                         success, determines that an Overpayment has been made,
                         any such Overpayment paid or distributed by the
                         Company to or for the benefit of Employee shall be
                         treated for all purposes as a loan ab initio to
                         Employee which Employee shall repay to the Company
                         together with interest at the applicable federal rate
                         provided for in Section 7872(f)(2) of the Code;
                         provided, however, that no such loan shall be deemed
                         to have been made and no amount shall be payable to
                         the Company if and to the extent such deemed loan and
                         payment would not either reduce the amount on which
                         Employee is subject to tax under Section 1 and Section
                         4999 of the Code or generate a refund of such taxes.
                         In the event that the Accounting Firm, based upon
                         controlling precedent or other substantial authority,
                         determines that an Underpayment has occurred, any such
                         Underpayment shall be promptly paid by the Company to
                         or for the benefit of Employee together with interest
                         at 120% of the applicable

                         the Code, compounded semiannually.

                 7.2     Notwithstanding anything in this Agreement to the
                         contrary, if after giving effect to the provisions of
                         Section 7.1 any portion of any payments to you by the
                         Company hereunder and any other present or future plan
                         or program of the Company or other present or future
                         agreement between you and the Company would not be
                         deductible by the Company for Federal income tax
                         purposes by reason of application of Section 162(m) of
                         the Code, then payment of that portion to you shall be
                         deferred until the earliest date upon which payment
                         thereof can be made to you without being
                         non-deductible pursuant to Section 162(m) of the Code.
                         In the event of such a deferral, the Company shall pay
                         interest to you on the amount deferred at 120% of the
                         applicable federal rate provided for in Section
                         7872(f)(2) of the Code, compounded semi-annually.

                         assignment, pledge, encumbrances or charge, and any

Mr. Lee A. Robbins
Vice President and Chief Financial Officer
Puritan-Bennett Corporation
9401 Indian Creek Parkway
P.O. Box 25905
Overland Park, KS  66225-5905

Dear Mr. Robbins:

        In view of your position as Vice President, Chief Financial Officer and
Controller at Puritan-Bennett Corporation (the "Company"), and in consideration
of your services in such capacity, the Board of Directors (the "Board") has
approved the commitment by the Company to you ("Employee") to provide you with
certain benefits in the event your employment is terminated for specified
reasons within two years after a Change of Control.  The purpose of this letter
agreement (the "Agreement") is to set forth the terms and conditions of the
Company's agreement with you concerning such benefits.

        1.       Termination Benefits.  If, within two years after the date of
a Change of Control, Employee's employment is terminated (a) by the Company for
any reason other than for Cause or Employee's death or Disability or (b) by
Employee for Good Reason, Employee will be entitled to receive the following
benefits:

                 1.1     Within 30 days following the Date of Termination, the
Company shall pay to you in a lump sum the present value, determined as of the
Date of Termination, of the amounts that you would have been paid by the
Company if, during the Continued Payment Period, the Company were to make
weekly payments to you each equal to one fifty-second of your Annual
Compensation.  Such payment shall be subject to all required withholdings.  The
Continued Payment Period shall commence on the Date of Termination, and shall
be a number of weeks determined by adding (a) the greater of (i) four or (ii)
two times the number of years Employee has been an employee of the Company
(rounding up to the next full year and excluding any intervening periods during
which Employee was not an employee of the Company), plus (b) two times the
number of $5,000 increments (rounded up to the next whole $5,000 increment)
contained in the Employee's Annual Compensation; provided, that the Continued
Payment Period shall not exceed two years.  Present value shall be determined
using a discount rate, compounded annually, equal to the yield- to-maturity of
a U.S. Treasury Bill with a remaining term equal to one-half of the Continued
Payment Period, as quoted in the edition of the Wall Street Journal first
published after the Date of Termination.  If Employee should die before
receiving all amounts payable to Employee hereunder, any unpaid amounts will be
paid to Employee's spouse, if living, and otherwise to Employee's estate.
Employee shall be entitled to receive interest on any amount payable hereunder
from the date payment was due to the date actually paid at the rate of the
lesser of 12% or the highest rate legally

permissible.  Employee will not be required to mitigate the amount of the
payments due to Employee hereunder by seeking other employment or otherwise.
Any amount earned by Employee as the result of employment by another employer
or otherwise after the Date of Termination shall not reduce the Company's
obligation to Employee hereunder.

                 1.2     Any outstanding unvested options held by Employee to
purchase stock of the Company that have not otherwise become exercisable under
the terms of the Company's stock option plans shall become fully vested and
exercisable.

                 1.3  COBRA Benefits.  The Company will provide a benefit under
the Consolidated Omnibus Budget Reconciliation Act of 1986 ("COBRA") and
Section 4980B of the Internal Revenue Code of 1986, as amended (the "Code"), as
follows:  the Company shall pay the percentage of the cost of COBRA coverage
with respect to your coverage status (e.g., individual or family) in effect
immediately prior to the Date of Termination, which percentage shall be the
fraction (expressed as a percentage), the numerator of which shall be the
difference between (i) the monthly cost of COBRA coverage for your coverage
status in effect immediately prior to the Date of Termination and (ii) your
monthly contribution toward your coverage in effect immediately prior to the
Date of Termination, and the denominator of which shall be the monthly cost of
COBRA coverage for your coverage status in effect immediately prior to the Date
of Termination.  All of such amounts shall be determined as of the day
immediately preceding the termination of Employee's employment.  The insurance
continuation benefits paid for hereunder shall be deemed to be part of
Employee's COBRA coverage.  Such benefits shall be in addition to any other
benefits relating to health or medical care benefits that are available under
the Company's policies to Employee following termination of employment.

                 1.4  Offset for Other Arrangements.  The severance benefits
provided hereunder will be reduced by the amount of any severance benefits to
which Employee is entitled under the Company's Severance Benefits policy for
terminated employees, or any other agreement between Employee and the Company
for severance benefits.

        2.       Notice of Termination.  Any termination by the Company for
Cause or by Employee for Good Reason shall be communicated by written notice to
the other party given by hand delivery or by registered or certified mail,
return receipt requested, postage prepaid, if to Employee, then to Employee at
his or her address as set forth in the Company's records, and, if to the
Company, to Puritan-Bennett Corporation, Human Relations Division, 9401 Indian
Creek Parkway, Overland Park, Kansas 66207.  Any notices given pursuant to this
paragraph 2 shall be effective the earlier of when such notice is actually
received by the addressee or three days after such notice is delivered or sent.

Bonus") immediately preceding the Date of Termination; or (b) the sum of (x)
the Employee's Base Salary in effect on the date of the Change of Control, plus

months) fiscal years immediately preceding the date of the Change of Control

has received a bonus).

                 3.2     "Cause" means (a) the Employee's willful violation of
any reasonable rule or direct order of the Board, the Company's Chief Executive

make reasonable efforts to correct within a reasonable time, or (b) conviction

involving actual moral turpitude or dishonesty of or by the Employee, or (c)
drug or alcohol abuse on Company premises or at a Company sponsored event, or
(d) the Employee's material violation of any provision of this Agreement,
which, after written notice to do so, the Employee fails to make reasonable
efforts to correct within a reasonable time.  "Cause" shall not include any
matter other than those specified in (a) through (d) above, and without
limiting the generality of the foregoing statement, Cause shall not include (x)
any charge or conviction of a crime, or entry of a plea of nolo contendere with
regard to a crime, under the Federal Food, Drug, and Cosmetic Act, as amended,
or any successor statute thereto (the "Act"), or (y) the imposition or attempt
to impose upon the Employee, or upon any operation, asset, product or activity
of the Company, of any other sanction or remedy under the Act, including
without limitation civil money penalties, warning letters, injunctions,
repairs, replacements, refunds, recalls or seizures, if the Employee acted in
good faith and in a manner which he reasonably believed to be in or not opposed
to the best interests of the Company.

                 3.3  Change of Control.  A "Change of Control" shall be deemed
to have occurred at any of the following times:

                                       the Company) by any person, entity or
                                       "group," within the meaning of Section
                                       13(d)(3) or 14(d)(2) of the Securities
                                       Exchange Act of 1934 (the "Exchange
                                       Act") (excluding, for this purpose, the
                                       Company or its affiliates, or any
                                       employee

                         3.3.2         At the time individuals who, as of the
                                       date hereof, constitute the Board (as of

                                       considered as though such person were a

                                       respect to which persons who were the
                                       shareholders of the Company immediately
                                       prior to such reorganization, merger or

                 3.4  "Date of Termination" means the date of receipt of the
written notice of termination pursuant to paragraph 2 or any later date
specified therein, as the case may be; provided, however, that (a) if
Employee's employment is terminated by the Company other than for Cause or by
reason of death or Disability, the Date of Termination shall be the date on
which the Company notifies Employee of such termination and (b) if Employee's
employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death or determination of Disability pursuant
to paragraph 3.5, as the case may be.

                 3.5  "Disability" means disability that, at least 26 weeks
after its commencement, is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to Employee or
Employee's legal representative (such acceptance not to be unreasonably
withheld).

                 3.6  "Good Reason" means (i) reduction of the Employee's base
salary, management bonus percentage or other compensation, as in effect
immediately prior to the Change of Control, (ii) failure to continue in effect
any medical, dental, accident, or disability plan in which the Employee is
entitled to participate immediately prior to the Change of Control and failure
to provide plans with substantially similar benefits (except that employee
contributions may be raised to the extent of any cost increases imposed by
third parties) or any action by the Company which would adversely affect the
Employee's participation or reduce the Employee's benefits under any of such
plans, (iii) material reduction in Employee's job responsibilities, (iv)
material reduction of Employee's title or position, (v) Employee shall be
requested to relocate to an office outside of the greater Kansas City
metropolitan area, or (vi) failure or refusal of any successor company to
assume the Company's obligations under this Agreement.

        4.       Nonexclusivity.  Nothing in this Agreement shall prevent or
limit Employee's continuing or future participation in any benefit, bonus,
incentive or other plans, programs, policies or practices provided by the
Company and for which Employee may otherwise qualify, nor shall anything herein
limit or otherwise affect such rights as any Employee may have under any stock
option or other agreements with the Company.  Except as otherwise expressly
provided herein, amounts which are vested benefits or which Employee is
otherwise entitled to receive under any plan, policy, practice or program of
the Company at or subsequent to the Date of Termination shall be payable in
accordance with such plan, policy, practice or program.

        5.       Successor to Company.  The Company shall require any successor
or assignee, whether direct or indirect, by purchase, merger, consolidation or
otherwise, to all or substantially all the business or assets of the Company,
expressly and unconditionally to assume and agree to perform the Company's
obligations under this Agreement, in the same manner and to the same extent
that the Company would be required to perform if no such succession or
assignment had taken place.  In such event, the term "Company," as used in





<PAGE>   6
Mr. Lee A. Robbins

Page 6



this Agreement, shall mean the Company as hereinafter defined and any successor
or assignee to the business or assets which by reason hereof becomes bound by
the terms and provisions of this Agreement.

        6.       Certain Reduction of Payments.

                 (a)     Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company to or for the benefit of Employee (whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise) (a "Payment") would be nondeductible by the Company for Federal
income tax purposes because of Section 280G of the Code, then the aggregate
present value of amounts payable or distributable as severance benefits
hereunder shall be reduced to the Reduced Amount.  The "Reduced Amount" shall
be an amount expressed in present value which maximizes the aggregate present
value of such severance benefits without causing any Payment to be
nondeductible by the Company because of Section 280G of the Code.  Anything to
the contrary notwithstanding, if the Reduced Amount is zero and it is
determined further that any Payment which is not part of the severance benefits
payable hereunder would nevertheless be nondeductible by the Company for
Federal income tax purposes because of Section 280G of the Code, then the
aggregate present value of Payments which are not severance benefits under this
Agreement shall also be reduced (but not below zero) to an amount expressed in
present value which maximizes the aggregate present value of Payments without
causing any payment to be nondeductible by the Company because of Section 280G
of the Code.  For purposes of this paragraph 6, present value shall be
determined in accordance with Section 280G(d)(4) of the Code.

                 (b)     All determinations required to be made under this
paragraph 6 shall be made by an accounting firm jointly selected by you and the
Company (the "Accounting Firm") and paid by the Company, and which may be the
Company's independent auditors.  The Accounting Firm shall provide detailed
supporting calculations both to the Company and Employee within 15 business
days of the Date of Termination or such earlier time as is requested by the
Company and an opinion to Employee that he or she has substantial authority not
to report any excise tax on his Federal income tax return with respect to any
Payments.  Any such determination by the Accounting Firm shall be binding upon
the Company and Employee.  Employee shall determine which and how much of the
Payments shall be eliminated or reduced consistent with the requirements of
this paragraph 6; provided that, if Employee does not make such determination
within ten business days of the receipt of the calculations made by the
Accounting Firm, the Company shall elect which and how much of the Payments
shall be eliminated or reduced consistent with the requirements of this
paragraph 6 and shall notify Employee promptly of such election; and provided
further that any Payments which do not constitute gross income to Employee
shall not be reduced or eliminated unless all other Payments have first been
eliminated.  Within five business days thereafter, the Company shall pay to or
distribute to or for the benefit of Employee such amounts as are then due to
Employee under this Agreement.

                 (c)     As a result of the uncertainty in the application of
Section 280G of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Payments will have been made by
the Company which should not have been made ("Overpayment") or that Payments
will not have been made by the Company which could have been made
("Underpayment"), in each case, consistent with the calculations required to be
made hereunder.  In the event that the Accounting Firm, based upon the
assertion of a deficiency by the Internal Revenue Service against Employee or
the Company which the Accounting Firm believes has a high probability of
success, determines that an Overpayment has been made, any such Overpayment
paid or distributed by the Company to or for the benefit of Employee shall be
treated for all purposes as a loan ab initio to Employee which Employee shall
repay to the Company together with interest at the applicable federal rate
provided for in Section 7872(f)(2) of the Code; provided, however, that no such
loan shall be deemed to have been made and no amount shall be payable to the
Company if and to the extent such deemed loan and payment would not either
reduce the amount on which Employee is subject to tax under Section 1 and
Section 4999 of the Code or generate a refund of such taxes.  In the event that
the Accounting Firm, based upon controlling precedent or other substantial
authority, determines that an Underpayment has occurred, any such Underpayment
shall be promptly paid by the Company to or for the benefit of Employee
together with interest at 120% of the applicable federal rate provided for in
Section 7872(f)(2) of the Code, compounded semiannually.

                 (d)     Notwithstanding anything in this Agreement to the
contrary, if after giving effect to the provisions of paragraphs 6(a)-(c) any
portion of any payments to Employee by the Company hereunder would not be
deductible by the Company for Federal income tax purposes by reason of
application of Section 162(m) of the Code, then payment of that portion to
Employee shall be deferred until the earliest date upon which payment thereof
can be made to Employee without being non-deductible pursuant to Section 162(m)
of the Code.  In the event of such a deferral, the Company shall pay interest
to you on the amount deferred at 120% of the applicable federal rate provided
for in Section 7872(f)(2) of the Code, compounded semiannually.

        7.       Amendments and Termination.  The Incumbent Board may from time
to time supplement, amend or terminate this Agreement or make any other
provisions which the Company may deem necessary or desirable, without the
approval of Employee; provided, however, that from and after such time there
has been a Change of Control, this Agreement shall not be amended in any manner
which would adversely affect the interests of Employee without the written
consent of Employee.  Subject to the foregoing, this Agreement establishes and
vests in Employee a contractual right to the benefits to which Employee is
entitled hereunder, enforceable by Employee against the Company.  The form of
any proper amendment or termination of this Agreement shall be a written
instrument signed by a duly authorized officer or officers of the Company
certifying that the amendment or termination has been approved by the Incumbent
Board.

        8.       Miscellaneous.

                 8.1  Employment Status.  This Agreement does not constitute a
contract of employment or impose on Employee or the Company any obligation to
retain Employee as an employee, to change the status of Employee's employment,
or to change the Company's policies regarding termination of employment.

                 8.2  No Assignment.  No benefit hereunder shall be subject to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or
charge, and any attempt to do so shall be void.

                 8.3  Governing Law.  This Agreement shall be governed by the
laws of the State of Kansas.

                 8.4  Expenses of Suit.  In the event of any dispute or
litigation between the Company and Employee arising out of this Agreement, the
prevailing party shall be entitled to recover its reasonable attorneys' fees
and expenses incurred in connection with the enforcement of its rights
hereunder.

                 8.5  Severability.  If any term, provision, covenants or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

                 8.6  Descriptive Headings.  Descriptive headings of the
several paragraphs of this Agreement are inserted for convenience only and
shall not control or affect the meaning or construction of any of the
provisions hereof.

                             SEVERANCE AGREEMENT

Mr. Derl S. Treff
Treasurer
Puritan-Bennett Corporation
9401 Indian Creek Parkway
P.O. Box 25905
Overland Park, KS  66225-5905

Dear Mr. Treff:

        In view of your position as Treasurer for Puritan-Bennett Corporation
(the "Company"), and in consideration of your services in such capacity, the
Board of Directors (the "Board") has approved the commitment by the Company to
you ("Employee") to provide you with certain benefits in the event your
employment is terminated for specified reasons within two years after a Change
of Control.  The purpose of this letter agreement (the "Agreement") is to set
forth the terms and conditions of the Company's agreement with you concerning
such benefits.

        1.       Termination Benefits.  If, within two years after the date of
a Change of Control, Employee's employment is terminated (a) by the Company for
any reason other than for Cause or Employee's death or Disability or (b) by
Employee for Good Reason, Employee will be entitled to receive the following
benefits:

                 1.1     Within 30 days following the Date of Termination, the
Company shall pay to you in a lump sum the present value, determined as of the
Date of Termination, of the amounts that you would have been paid by the
Company if, during the Continued Payment Period, the Company were to make
weekly payments to you each equal to one fifty-second of your Annual
Compensation.  Such payment shall be subject to all required withholdings.  The
Continued Payment Period shall commence on the Date of Termination, and shall
be a number of weeks determined by adding (a) the greater of (i) four or (ii)
two times the number of years Employee has been an employee of the Company
(rounding up to the next full year and excluding any intervening periods during
which Employee was not an employee of the Company), plus (b) two times the
number of $5,000 increments (rounded up to the next whole $5,000 increment)
contained in the Employee's Annual Compensation; provided, that the Continued
Payment Period shall not exceed two years.  Present value shall be determined
using a discount rate, compounded annually, equal to the yield- to-maturity of
a U.S. Treasury Bill with a remaining term equal to one-half of the Continued
Payment Period, as quoted in the edition of the Wall Street Journal first
published after the Date of Termination.  If Employee should die before
receiving all amounts payable to Employee hereunder, any unpaid amounts will be
paid to Employee's spouse, if living, and otherwise to Employee's estate.
Employee shall be entitled to receive interest on any amount payable hereunder
from the date payment was due to the date actually paid at the rate of the
lesser of 12% or the highest rate legally permissible.  Employee will not be
required to mitigate the amount of the payments due to Employee hereunder by
seeking other employment or otherwise.  Any amount earned by

Page 2



Employee as the result of employment by another employer or otherwise after the
Date of Termination shall not reduce the Company's obligation to Employee
hereunder.

                 1.2  Any outstanding unvested options held by Employee to
purchase stock of the Company that have not otherwise become exercisable under
the terms of the Company's stock option plans shall become fully vested and
exercisable.

                 1.3  COBRA Benefits.  The Company will provide a benefit under
the Consolidated Omnibus Budget Reconciliation Act of 1986 ("COBRA") and
Section 4980B of the Internal Revenue Code of 1986, as amended (the "Code"), as
follows:  the Company shall pay the percentage of the cost of COBRA coverage
with respect to your coverage status (e.g., individual or family) in effect
immediately prior to the Date of Termination, which percentage shall be the
fraction (expressed as a percentage), the numerator of which shall be the
difference between (i) the monthly cost of COBRA coverage for your coverage
status in effect immediately prior to the Date of Termination and (ii) your
monthly contribution toward your coverage in effect immediately prior to the
Date of Termination, and the denominator of which shall be the monthly cost of
COBRA coverage for your coverage status in effect immediately prior to the Date
of Termination.  All of such amounts shall be determined as of the day
immediately preceding the termination of Employee's employment.  The insurance
continuation benefits paid for hereunder shall be deemed to be part of
Employee's COBRA coverage.  Such benefits shall be in addition to any other
benefits relating to health or medical care benefits that are available under
the Company's policies to Employee following termination of employment.

                 1.4  Offset for Other Arrangements.  The severance benefits
provided hereunder will be reduced by the amount of any severance benefits to
which Employee is entitled under the Company's Severance Benefits policy for
terminated employees, or any other agreement between Employee and the Company
for severance benefits.

        2.       Notice of Termination.  Any termination by the Company for
Cause or by Employee for Good Reason shall be communicated by written notice to
the other party given by hand delivery or by registered or certified mail,
return receipt requested, postage prepaid, if to Employee, then to Employee at
his or her address as set forth in the Company's records, and, if to the
Company, to Puritan-Bennett Corporation, Human Relations Division, 9401 Indian
Creek Parkway, Overland Park, Kansas 66207.  Any notices given pursuant to this
paragraph 2 shall be effective the earlier of when such notice is actually
received by the addressee or three days after such notice is delivered or sent.

        3.       Definitions.

                 3.1     "Annual Compensation" means the greater of (a) the sum
of (i) the Employee's annual base salary ("Base Salary") in effect on the Date
of Termination, plus (ii) the annual average of the Employee's incentive bonus
payments under the Company's

Management Incentive Bonus Plan or any successor thereto with respect to the
three full (12 months) fiscal years ("Average Bonus") immediately preceding the
Date of Termination; or (b) the sum of (x) the Employee's Base Salary in effect
on the date of the Change of Control, plus (y) the Employee's Average Bonus
computed with respect to the three full (12 months) fiscal years (or applicable
shorter period) immediately preceding the date of the Change of Control
(provided, if Employee has not been employed by the Company during all of the
three full fiscal years immediately preceding the Date of Termination or the
date of the Change of Control, as the case may be, then "Average Bonus" shall
mean the annualized average of the bonus payments received by the Employee,
computed based on the actual period of Employee's employment with the Company
during any full fiscal year(s) of the Company with respect to which Employee
has received a bonus).

                 3.2     "Cause" means (a) the Employee's willful violation of
any reasonable rule or direct order of the Board, the Company's Chief Executive
Officer ("CEO") or other elected officer, where such officer is Employee's
direct supervisor, which, after written notice to do so, the Employee fails to
make reasonable efforts to correct within a reasonable time, or (b) conviction
of a crime, or entry of a plea of nolo contendere with regard to a crime,
involving actual moral turpitude or dishonesty of or by the Employee, or (c)
drug or alcohol abuse on Company premises or at a Company sponsored event, or
(d) the Employee's material violation of any provision of this Agreement,
which, after written notice to do so, the Employee fails to make reasonable
efforts to correct within a reasonable time.  "Cause" shall not include any
matter other than those specified in (a) through (d) above, and without
limiting the generality of the foregoing statement, Cause shall not include (x)

                         3.3.2         At the time individuals who, as of the
                                       date hereof, constitute the Board (as of
                                       the date hereof, the "Incumbent Board")

                                       purposes of this subsection 3.3.2,
                                       considered as though such person were a
                                       member of the Incumbent Board; or

                                       consolidation do not, immediately
                                       thereafter, own more than 50% of the

                 3.4  "Date of Termination" means the date of receipt of the
written notice of termination pursuant to paragraph 2 or any later date
specified therein, as the case may be; provided, however, that (a) if
Employee's employment is terminated by the Company other than for Cause or by
reason of death or Disability, the Date of Termination shall be the date on
which the Company notifies Employee of such termination and (b) if Employee's
employment is terminated by reason of death or Disability, the Date of
Termination shall be the date of death or determination of Disability pursuant
to paragraph 3.5, as the case may be.

                 3.5  "Disability" means disability that, at least 26 weeks
after its commencement, is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to Employee or
Employee's legal representative (such acceptance not to be unreasonably
withheld).

                 3.6  "Good Reason" means (i) reduction of the Employee's base
salary, management bonus percentage or other compensation, as in effect
immediately prior to the Change of Control, (ii) failure to continue in effect
any medical, dental, accident, or disability plan in which the Employee is
entitled to participate immediately prior to the Change of Control and failure
to provide plans with substantially similar benefits (except that employee
contributions may be raised to the extent of any cost increases imposed by
third parties) or any action by the Company which would adversely affect the
Employee's participation or reduce the Employee's benefits under any of such
plans, (iii) material reduction in Employee's job responsibilities, (iv)
material reduction of Employee's title or position, (v) Employee shall be
requested to relocate to an office outside of the greater Kansas City
metropolitan area, or (vi) failure or refusal of any successor company to
assume the Company's obligations under this Agreement.

        4.       Nonexclusivity.  Nothing in this Agreement shall prevent or
limit Employee's continuing or future participation in any benefit, bonus,
incentive or other plans, programs, policies or practices provided by the
Company and for which Employee may otherwise qualify, nor shall anything herein
limit or otherwise affect such rights as any Employee may have under any stock
option or other agreements with the Company.  Except as otherwise expressly
provided herein, amounts which are vested benefits or which Employee is
otherwise entitled to receive under any plan, policy, practice or program of
the Company at or subsequent to the Date of Termination shall be payable in
accordance with such plan, policy, practice or program.

        5.       Successor to Company.  The Company shall require any successor
or assignee, whether direct or indirect, by purchase, merger, consolidation or
otherwise, to all or substantially all the business or assets of the Company,
expressly and unconditionally to assume and agree to perform the Company's
obligations under this Agreement, in the same manner and to the same extent
that the Company would be required to perform if no such succession or
assignment had taken place.  In such event, the term "Company," as used in

this Agreement, shall mean the Company as hereinafter defined and any successor
or assignee to the business or assets which by reason hereof becomes bound by
the terms and provisions of this Agreement.

        6.       Certain Reduction of Payments.

                 (a)     Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company to or for the benefit of Employee (whether paid or
payable or distributed or distributable pursuant to the terms of this Agreement
or otherwise) (a "Payment") would be nondeductible by the Company for Federal
income tax purposes because of Section 280G of the Code, then the aggregate
present value of amounts payable or distributable as severance benefits
hereunder shall be reduced to the Reduced Amount.  The "Reduced Amount" shall
be an amount expressed in present value which maximizes the aggregate present
value of such severance benefits without causing any Payment to be
nondeductible by the Company because of Section 280G of the Code.  Anything to
the contrary notwithstanding, if the Reduced Amount is zero and it is
determined further that any Payment which is not part of the severance benefits
payable hereunder would nevertheless be nondeductible by the Company for
Federal income tax purposes because of Section 280G of the Code, then the
aggregate present value of Payments which are not severance benefits under this
Agreement shall also be reduced (but not below zero) to an amount expressed in
present value which maximizes the aggregate present value of Payments without
causing any payment to be nondeductible by the Company because of Section 280G
of the Code.  For purposes of this paragraph 6, present value shall be
determined in accordance with Section 280G(d)(4) of the Code.

                 (b)     All determinations required to be made under this
paragraph 6 shall be made by an accounting firm jointly selected by you and the
Company (the "Accounting Firm") and paid by the Company, and which may be the
Company's independent auditors.  The Accounting Firm shall provide detailed
supporting calculations both to the Company and Employee within 15 business
days of the Date of Termination or such earlier time as is requested by the
Company and an opinion to Employee that he or she has substantial authority not
to report any excise tax on his Federal income tax return with respect to any
Payments.  Any such determination by the Accounting Firm shall be binding upon
the Company and Employee.  Employee shall determine which and how much of the
Payments shall be eliminated or reduced consistent with the requirements of
this paragraph 6; provided that, if Employee does not make such determination
within ten business days of the receipt of the calculations made by the
Accounting Firm, the Company shall elect which and how much of the Payments
shall be eliminated or reduced consistent with the requirements of this
paragraph 6 and shall notify Employee promptly of such election; and provided
further that any Payments which do not constitute gross income to Employee
shall not be reduced or eliminated unless all other Payments have first been
eliminated.  Within five business days thereafter, the Company shall pay to or
distribute to or for the benefit of Employee such amounts as are then due to
Employee under this Agreement.

                 (c)     As a result of the uncertainty in the application of
Section 280G of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Payments will have been made by
the Company which should not have been made ("Overpayment") or that Payments
will not have been made by the Company which could have been made
("Underpayment"), in each case, consistent with the calculations required to be
made hereunder.  In the event that the Accounting Firm, based upon the
assertion of a deficiency by the Internal Revenue Service against Employee or
the Company which the Accounting Firm believes has a high probability of
success, determines that an Overpayment has been made, any such Overpayment
paid or distributed by the Company to or for the benefit of Employee shall be
treated for all purposes as a loan ab initio to Employee which Employee shall
repay to the Company together with interest at the applicable federal rate
provided for in Section 7872(f)(2) of the Code; provided, however, that no such
loan shall be deemed to have been made and no amount shall be payable to the
Company if and to the extent such deemed loan and payment would not either
reduce the amount on which Employee is subject to tax under Section 1 and
Section 4999 of the Code or generate a refund of such taxes.  In the event that
the Accounting Firm, based upon controlling precedent or other substantial
authority, determines that an Underpayment has occurred, any such Underpayment
shall be promptly paid by the Company to or for the benefit of Employee
together with interest at 120% of the applicable federal rate provided for in
Section 7872(f)(2) of the Code, compounded semiannually.

                 (d)     Notwithstanding anything in this Agreement to the
contrary, if after giving effect to the provisions of paragraphs 6(a)-(c) any
portion of any payments to Employee by the Company hereunder would not be
deductible by the Company for Federal income tax purposes by reason of
application of Section 162(m) of the Code, then payment of that portion to
Employee shall be deferred until the earliest date upon which payment thereof
can be made to Employee without being non-deductible pursuant to Section 162(m)
of the Code.  In the event of such a deferral, the Company shall pay interest
to you on the amount deferred at 120% of the applicable federal rate provided
for in Section 7872(f)(2) of the Code, compounded semiannually.

        7.       Amendments and Termination.  The Incumbent Board may from time
to time supplement, amend or terminate this Agreement or make any other
provisions which the Company may deem necessary or desirable, without the
approval of Employee; provided, however, that from and after such time there
has been a Change of Control, this Agreement shall not be amended in any manner
which would adversely affect the interests of Employee without the written
consent of Employee.  Subject to the foregoing, this Agreement establishes and
vests in Employee a contractual right to the benefits to which Employee is
entitled hereunder, enforceable by Employee against the Company.  The form of
any proper amendment or termination of this Agreement shall be a written
instrument signed by a duly authorized officer or officers of the Company
certifying that the amendment or termination has been approved by the Incumbent
Board.

        8.       Miscellaneous.

                 8.1  Employment Status.  This Agreement does not constitute a
contract of employment or impose on Employee or the Company any obligation to
retain Employee as an employee, to change the status of Employee's employment,
or to change the Company's policies regarding termination of employment.

                 8.2  No Assignment.  No benefit hereunder shall be subject to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or
charge, and any attempt to do so shall be void.

                 8.3  Governing Law.  This Agreement shall be governed by the
laws of the State of Kansas.

                 8.4  Expenses of Suit.  In the event of any dispute or
litigation between the Company and Employee arising out of this Agreement, the
prevailing party shall be entitled to recover its reasonable attorneys' fees
and expenses incurred in connection with the enforcement of its rights
hereunder.

                 8.5  Severability.  If any term, provision, covenants or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

                 8.6  Descriptive Headings.  Descriptive headings of the
several paragraphs of this Agreement are inserted for convenience only and
shall not control or affect the meaning or construction of any of the
provisions hereof.

                 FIRST AMENDMENT TO PURITAN-BENNETT CORPORATION
                       MANAGEMENT INCENTIVE BONUS PLAN A


        THIS AMENDMENT of the Puritan-Bennett Corporation Management Incentive
Bonus Plan A (the "Plan") is made by the Puritan-Bennett Corporation (which,
together with its subsidiaries and affiliates, shall be referred to herein as
the "Corporation"), effective as of the 7th day of November, 1994.

        WHEREAS, as part of the Plan, the Corporation reserved the right, at
any time, by action of its Board of Directors, to modify or amend, in whole or
in part, any or all provisions of the Plan; and

        WHEREAS, the Corporation now desires to amend the Plan.

        NOW, THEREFORE, the Plan is hereby amended as follows:

        1.       Section e)1. on page 6 of the Plan is hereby amended by the
                 addition of the following at the end of such section:

                 ; provided that in the event that a participant is terminated
        without Cause (as defined below) or resigns for Good Reason (as defined
        below) within two years following a Change in Control (as defined
        below), the Company shall pay to the participant as soon as possible
        following such termination the maximum bonus amount for which such
        participant was eligible with respect to the fiscal year of
        termination, prorated to the date of termination.  The following
        definitions shall apply:

                 "Cause" means (a) a participant's willful violation of any
                 reasonable rule or direct order of the Board or the Company's
                 Chief Executive Officer ("CEO") or other elected officer,
                 where such officer is the participant's direct supervisor,
                 which, after written notice to do so, the participant fails to
                 make reasonable efforts to correct within a reasonable time,
                 or (b) conviction of a crime, or entry of a plea of nolo
                 contendere with regard to a crime, involving actual moral
                 turpitude or dishonesty of or by the participant, or (c) drug
                 or alcohol abuse on Company premises or at a Company sponsored
                 event, or (d) the participant's material violation of any
                 provision of this Agreement, which, after written notice to do
                 so, the participant fails to make reasonable efforts to
                 correct within a reasonable time.  "Cause" shall not include
                 any matter other than these specified in (a) through (d)
                 above, and without limiting the generality of the foregoing
                 statement, Cause shall not include (x) any charge or
                 conviction of a crime, or entry of a plea of nolo contendere
                 with regard to a crime, under the Federal Food, Drug, and
                 Cosmetic Act, as amended, or any successor statute thereto

                 Profit for bonus determination will be inclusive of any
                 changes in reserves, but will exclude any capital gains or
                 losses, other unusual gains or losses such as proceeds of fire
                 or casualty insurance, and extraordinary items.  In cases of

                 measuring such profits, and distortions in the methods used to
                 determine and measure the realization of the performance
                 targets hereunder for bonus calculation purposes, that have

                 the Compensation Committee shall have the authority, in its
                 sole and absolute discretion, to adjust the performance
                 targets hereunder for bonus calculation purposes to remove
                 distortions in the realization of such targets and distortions
                 in the method of measuring such realization and such targets,
                 caused by actions taken or expenses incurred by the Company in
                 connection with a proposal for a transaction described in
                 subparagraphs A or C of the definition of Change of Control
                 set forth in subsection e)1. above, or any other extraordinary
                 transaction, whether or not consummated.  No changes in
                 reserves shall be taken into account for purposes of bonus
                 calculations hereunder with respect to the fiscal year in
                 which a Change of Control occurs and the immediately following
                 fiscal year.

        IN WITNESS WHEREOF, the Corporation has executed this Amendment to the
Plan, effective as of the date first written above.

                 addition of the following at the end of such section:

                 ; provided that in the event that a participant is terminated
        without Cause (as defined below) or resigns for Good Reason (as defined

                 remove distortions in the Company's profits, and distortions
                 in the method of measuring such profits, and distortions in
                 the methods used to

                 determine and measure the realization of the performance
                 targets hereunder for bonus calculation purposes, that have

                 connection with a proposal for a transaction described in
                 subparagraphs A or C of the definition of Change of Control
                 set forth in subsection e)1. above, or any other extraordinary
                 transaction, whether or not consummated.  No changes in
                 reserves shall be taken into account for purposes of bonus
                 calculations hereunder with respect to the fiscal year in
                 which a Change of Control occurs and the immediately following

                          PURITAN-BENNETT CORPORATION
                      SUPPLEMENTAL RETIREMENT BENEFIT PLAN


        THIS AMENDMENT to the Puritan-Bennett Corporation Supplemental
Retirement Benefit Plan (the "Plan") is made effective as of the 1st day of
September, 1993 by Puritan-Bennett Corporation, a Delaware corporation
(hereinafter referred to as the "Corporation").

        WHEREAS, the Corporation has adopted the Plan effective as of September
1, 1985, which provides benefits that supplement benefits provided under the
Restated Puritan-Bennett Pension Plan (the "Qualified Plan"); and

        WHEREAS, the Corporation and the participants in the Plan have agreed
to amendment of the Plan in the manner set forth below.

        NOW, THEREFORE, the Plan is amended effective as of September 1, 1993
as follows:

        1.   Section 2.02, the definition of "Average Monthly Compensation," is
        amended in its entirety to read as follows:

                 Section 2.02.  The term "Average Monthly Compensation" shall
        have the meaning provided in the Qualified Plan (currently Section 2.08
        thereof), provided that the dollar limitation on Compensation provided
        in the Qualified Plan (currently Section 2.14 thereof) shall not be
        applicable for purposes of determining Average Monthly Compensation
        under this Plan.

        2.   Section 2.03, the definition of "Beneficiary," is amended in its
        entirety to read as follows:

                 Section 2.03.  The term "Beneficiary" shall have the meaning
        provided for in the Qualified Plan (currently Section 2.09 thereof).

        3.   Section 2.13, the definition of "Years of Service," is amended in
        its entirety to read as follows:

                 Section 2.13.  The term "Years of Service" shall mean the
        number of years for which a Member is given credit for the purpose of
        determining eligibility for benefits (vesting) under the Qualified Plan
        (as currently defined in Section 2.41 of the Qualified Plan).

        4.   Section 2, "Definitions," shall be amended by the addition of the
        following new Section 2.14:





<PAGE>   2





                 Section 2.14.  The term "Years of Participation" shall mean
        the number of years (twelve month periods) of the Member's
        participation in this Plan, measured from the date he first became a
        Member (as herein defined) to the date of his termination of
        employment.

        5.   The first paragraph of Section 4.01 is amended in its entirety to
        read as follows:

                 Section 4.01-Supplemental Monthly Retirement Benefit.  A
        Member who has at the date of his termination of employment with an
        Employer attained age fifty-five (55) and completed seven (7) Years of
        Participation shall be entitled to a Supplemental Monthly Retirement
        Benefit.  Such Supplemental Monthly Retirement Benefit, payable in the
        form of a single life annuity (the "Normal Form"), shall be an amount
        equal to the percentage of the Member's Average Monthly Compensation
        specified in such Member's Plan Agreement, reduced by an amount
        computed under Section 4.01(a).  The amount so reduced shall be further
        adjusted based upon the vesting schedule set out in Section 4.01(b).
        The amount resulting from the application of Sections 4.01(a) and (b)
        shall then be adjusted as provided in Section 4.01(c).

        6.       Section 4, "Retirement Benefits," shall be amended by the
        addition of the following new Section 4.02:

                 Section 4.02-Time of Commencement of Supplemental Monthly
        Retirement Benefit.  Payment of the Supplemental Monthly Retirement
        Benefit to which a Member is entitled pursuant to Section 4.01 shall
        commence as of the first day of the calendar month coinciding with or
        next following the termination of the Member's employment (the "Benefit
        Commencement Date").  Actual payment of such Supplemental Monthly
        Retirement Benefit, in the Normal Form or other form provided in
        Section 4.03, shall, however,  be subject to the following:  if the
        Member shall have elected the form of payment of his Supplemental
        Monthly Retirement Benefit pursuant to Section 4.03 during a calendar
        year (a "Preceding Year") preceding the calendar year during which his
        termination of employment occurs (the "Termination Year"), then actual
        payment of his Supplemental Monthly Retirement Benefit shall commence
        on or as soon as practical following his Benefit Commencement Date; if
        the Member did not make an election pursuant to Section 4.03 during a
        Preceding Year, but shall make such an election during the Termination
        Year, actual payment of his Supplemental Monthly Retirement Benefit
        shall commence on the first day of the next following calendar year
        (the "Succeeding Year"); if the Member does not make an election
        pursuant to Section 4.03 during either a Preceding or the Termination
        Year, then such Member shall be deemed to have elected to receive
        payment in the Normal Form single life annuity commencing on the first
        day of the Succeeding Year; provided that any time actual payment of a
        Member's Supplemental Monthly Retirement Benefit shall not commence on
        his Benefit Commencement Date, then the first payment made shall
        include all payments that would have been made on or before such actual
        commencement date if actual payment had commenced on the Benefit
        Commencement Date, together with interest on all deferred payments
        (from the





                                     -2-
<PAGE>   3



        date each such payment would have been made if actual payment had
        commenced on the Benefit Commencement Date) at the Most Applicable
        Treasury Security Rate compounded annually.  The "Most Applicable
        Treasury Security Rate" shall be the yield-to-maturity of the Treasury
        Bill with a remaining term equal to one-half of the period beginning on
        the Benefit Commencement Date and ending on the date payments actually
        commence, as quoted in the edition of the Wall Street Journal first
        published after the Benefit Commencement Date.

        7.   Section 4, "Retirement Benefits," shall be amended by the addition
        of the following new Section 4.03:

                 Section 4.03-Form of Payment of Supplemental Monthly
        Retirement Benefits.  The "Normal Form" of payment of a Member's
        Supplemental Monthly Retirement Benefit, and the form on which the
        amount of such Benefit is calculated pursuant to Section 4.01, shall be
        a single life annuity payable for the Member's life only commencing as
        of his Benefit Commencement Date.  A Member may, however, elect in
        writing filed with the Committee prior to the end of the Termination
        Year, to receive payment of his Supplemental Monthly Retirement Benefit
        in one of the following optional forms, each of which will be the
        "Actuarial Equivalent" (which term shall have the meaning provided in
        the Qualified Plan as of the Member's Benefit Commencement Date) of the
        Normal Form single life annuity.

                         (a)  Ten Year Certain and Continuous Option.  Pursuant
                 to this option, the Member's Supplemental Monthly Retirement
                 Benefit shall be payable during the Member's life only;
                 provided that if the Member dies within ten years of his
                 Benefit Commencement Date, payments in the same amount will
                 continue to be made to the Member's Beneficiary until a total
                 of 120 monthly payments have been made.

                         (b)  Early Retirement Level Income Option.  Pursuant
                 to this option, the Member's Supplemental Monthly Retirement
                 Benefit payments will be made during the Member's life only.
                 Larger payments shall be made until the first day the Member
                 is eligible to receive social security benefits (age 62).  At
                 that time payments to the Member shall be reduced by the
                 amount of the Member's social security benefit that was
                 estimated as part of the determination of all payments to be
                 made under this Section 4.03(c).  No payments shall be made
                 after the Member's death.

                         (c)  50%, 75% and 100% Contingent Annuitant Option.
                 Pursuant to this option, the Member's Supplemental Monthly
                 Retirement Benefit payments shall be made during the life of
                 the Member, with payments continuing to the Member's
                 designated contingent annuitant ("Contingent Annuitant") for
                 the life of such Contingent Annuitant following the Member's
                 death.  The Contingent Annuitant and the percentage to be paid
                 to such Contingent Annuitant must be designated by the Member
                 at the time this payment form is elected.  If the Contingent
                 Annuitant predeceases the Member, no benefits shall be paid
                 after the Member's death.  The amount





                                     -3-
<PAGE>   4



                 paid to the Member's Contingent Annuitant shall be either 50%,
                 75% or 100% of the amount received by the Member during the
                 Member's life.

        8.       Section 5, "Death Benefits", is amended in its entirety to
                 read as follows:

                 Section 5-Death Benefits.

                 Section 5.01-Death Before Commencement of Benefits.  In the
        event of the death of a Member or a Disabled Member prior to his
        Benefit Commencement Date, leaving a surviving Spouse, then if such
        Member had prior to his death completed seven (7) Years of
        Participation, his surviving Spouse shall be entitled to a Death
        Benefit in the form of a monthly annuity payable for the life of the
        Spouse only.  The monthly Death Benefit shall be an amount equal to 50%
        of the annuity amount which would have been payable to the Member
        during his life if he had survived, terminated employment at the later
        of age fifty-five (55) or the date of his death, elected immediate
        payment in the form of a 50% contingent annuity pursuant to Section
        4.03(c) and designated his Spouse as the contingent annuitant.  If the
        Member had not attained age fifty-five (55) at the time of his death,
        payment of the Death Benefit hereunder to his surviving Spouse will not
        commence until the date that the deceased Member would have attained
        age fifty- five (55), and no Death Benefit shall be payable in the
        event his surviving Spouse shall die before such date.  No Death
        Benefit will be paid hereunder if the Member dies before his Benefit
        Commencement Date and is not then married.

                 Section 5.02-Death After Commencement of Benefits.  If the
        Member dies after his Benefit Commencement Date, the Member's
        Beneficiary shall be entitled to receive, in a single lump sum, a
        Special Death Benefit in an amount equal to twelve (12) times the
        monthly Supplemental Monthly Retirement Benefit calculated on the basis
        of the Normal Form single life annuity (regardless of the form in which
        such Member's Supplemental Monthly Retirement Benefit was being paid or
        was payable prior to his death).  If the Member dies following his
        Benefit Commencement Date, no other or additional death benefits will
        be payable except to the extent provided under any optional form of
        payment selected by the Member.

        9.       New Section 9.03 is added to the Plan to read as follows:

                 Section 9.03-Plan Interpretation.  The Corporation shall have
        sole and absolute discretion and authority to interpret all provisions
        of this Plan and to resolve all questions arising under this Plan;
        including, but not limited to, determining whether any person is
        eligible to contribute to this Plan, whether any person shall receive
        any payments pursuant to this Plan, and the amount of any payments to
        be paid pursuant to this Plan.  Any interpretation, resolution or
        determination of the Corporation pursuant to this Section shall be
        final and binding upon all concerned.

         WHEREAS, the Corporation has adopted the Puritan-Bennett Corporation

"Plan"), which provides benefits that supplement benefits provided under the
Restated Puritan-Bennett Pension Plan (the "Pension Plan"); and

agreement pursuant to which the Employee became a Member under the terms of the
Plan; and

         NOW, THEREFORE, in consideration of the mutual covenants set forth
herein, the Employee and the Corporation agree that:

                 A.     Section 4, "Retirement Benefits," shall be amended by
         the addition of the following new Section 4.04.

                 Section 4.04-Exceptions for Certain Terminations of
         Employment.  Notwithstanding the foregoing provisions of this Section
         4 or any other provision(s) of this Plan, in the event of the
         termination of employment of a Member within two years following the
         occurrence of a Change in Control for Good Reason (if initiated by the
         Member), and/or other than for Cause (if initiated by the
         Corporation), then (a) even if the Member has not at the date of
         termination of employment attained age fifty-five (55) and/or
         completed seven (7) Years of Participation, he shall nevertheless be
         entitled to the Supplemental Monthly Retirement Benefit provided under
         Section 4.01 hereof; (b) the Member shall be deemed to have completed
         ten or more Years of Service and to be 100% vested in the Supplemental
         Monthly Retirement Benefit pursuant to Section 4.01(b) hereof; and (c)
         the Member shall be deemed to have been age sixty- five (65) (unless
         his actual age shall be greater) at the date of termination of
         employment so as to be entitled to 100% of the Supplemental Monthly
         Retirement Benefit (as adjusted by Section 4.01(a)) pursuant to
         Section 4.01(c).

                        employment agreement with the Corporation, which, after
                        written notice to do so, the Member fails to make
                        reasonable efforts to correct within a reasonable time.
                        "Cause" shall not include any matter other than these

                        letters, injunctions, repairs, replacements, refunds,
                        recalls or seizures, if the Member acted in good faith
                        and in a manner which he reasonably believed to be in
                        or not opposed to the best interests of the
                        Corporation.

                        effect any medical, dental, accident, or disability
                        plan in which the Member is entitled to participate
                        immediately prior to the Change in Control and failure
                        to provide plans with substantially similar benefits
                        (except that employee contributions may be raised to

                        assume the Corporation's obligations under the
                        Employment Agreement.

                                     in Rule 14a-11 of Regulation 14A
                                     promulgated under the Exchange Act) shall
                                     be, for purposes of this subsection 1.3.2,
                                     considered as though such person were a
                                     member of the Incumbent Board; or

                        (iii)        Upon the approval by the shareholders of
                                     the Corporation of a reorganization,
                                     merger, consolidation (in each case, with
                                     respect to which persons who were the
                                     shareholders of the Corporation
                                     immediately prior to such reorganization,

                        (iv)         The occurrence of any other event which
                                     the Incumbent Board in its sole discretion
                                     determines constitutes a Change in
                                     Control.

                 B.     A new Section 11 is added to read in its entirety as
         follows:

                        Section 11--Certain Reduction of Payments.

                               (a)   Anything in this Agreement to the contrary
                        notwithstanding, in the event it shall be determined
                        that any payment or distribution by the Corporation to
                        or for the benefit of Member (whether paid or payable
                        or distributed or distributable pursuant to the terms
                        of this Agreement or otherwise) (a "Payment") would be
                        nondeductible by the Corporation for Federal income tax
                        purposes because of Section 280G of the Internal
                        Revenue Code of 1986, as amended (the "Code"), then the
                        aggregate present value of amounts payable or
                        distributable hereunder shall be reduced to the Reduced
                        Amount; provided, however, that Payments shall not
                        include any amount payable pursuant to the Agreement
                        between Member and the Corporation dated April 25,
                        1980.  The "Reduced Amount" shall be an amount
                        expressed in present value which maximizes the
                        aggregate present value of such benefits without
                        causing any Payment to be nondeductible by the
                        Corporation because of Section 280G of the Code.
                        Anything to the contrary notwithstanding, if the
                        Reduced Amount is zero and it is determined further
                        that any Payment which is not part of the benefits
                        payable hereunder would nevertheless be nondeductible
                        by the Corporation for Federal income tax purposes
                        because of Section 280G of the Code, then the aggregate
                        present value of Payments which are not benefits
                        hereunder shall also be reduced (but not below zero) to
                        an amount expressed in present value which maximizes
                        the aggregate present value of Payments without causing
                        any payment to be nondeductible by the Corporation
                        because of Section 280G of the Code.  For purposes of
                        this Section 11, present value shall be determined in
                        accordance with Section 280G(d)(4) of the Code.

                               (b)   All determinations required to be made
                        under this Section 11 shall be made by an accounting
                        firm jointly selected by Member and the Corporation
                        (the "Accounting Firm") and paid by the Corporation,
                        and which may be the Company's independent auditors.
                        The Accounting Firm shall provide detailed supporting
                        calculations both to the Corporation and Member within
                        15 business days of the date of termination of Member's
                        employment by the Corporation (the "Employment
                        Termination Agreement") or such earlier time as is
                        requested by the Corporation and an opinion to Member
                        that he has substantial authority not to report any
                        excise tax on his Federal income tax return with
                        respect to any Payments.  Any such determination by the
                        Accounting Firm shall be binding upon the Corporation
                        and Member.  Member shall determine which and how much
                        of the Payments, shall be eliminated or reduced
                        consistent with

                        the requirements of this Section 11, provided that, if
                        Member does not make such determination within ten
                        business days of the receipt of the calculations made
                        by the Accounting Firm, the Corporation shall elect
                        which and how much of the Payments shall be eliminated
                        or reduced consistent with the requirements of this
                        Section 11 and shall notify Member promptly of such
                        election; and provided further that any Payments which
                        do not constitute gross income to Member shall not be
                        reduced or eliminated unless all other Payments have
                        first been eliminated.  Within five business days
                        thereafter, the Corporation shall pay to or distribute
                        to or for the benefit of Employee such amounts as are
                        then due to Member under this Agreement.

                               (c)   As a result of the uncertainty in the
                        application of Section 280G of the Code at the time of
                        the initial determination by the Accounting Firm
                        hereunder, it is possible that Payments will have been
                        made by the Corporation which should not have been made
                        ("Overpayment") or that Payments will not have been
                        made by the Corporation which could have been made
                        ("Underpayment"), in each case, consistent with the
                        calculations required to be made hereunder.  In the
                        event that the Accounting Firm, based upon the
                        assertion of a deficiency by the Internal Revenue
                        Service against Member or the Corporation which the
                        Accounting Firm believes has a high probability of
                        success, determines that an Overpayment has been made,
                        any such Overpayment paid or distributed by the
                        Corporation to or for the benefit of Member shall be
                        treated for all purposes as a loan ab initio to Member
                        which Member shall repay to the Corporation together
                        with interest at the applicable federal rate provided
                        for in Section 7872(f)(2) of the Code; provided,
                        however, that no such loan shall be deemed to have been
                        made and no amount shall be payable to the Corporation
                        if and to the extent such deemed loan and payment would
                        not either reduce the amount on which Member is subject
                        to tax under Section 1 and Section 4999 of the Code or
                        generate a refund of such taxes.  In the event that the
                        Accounting Firm, based upon controlling precedent or
                        other substantial authority, determines that an
                        Underpayment has occurred, any such Underpayment shall
                        be promptly paid by the Corporation to or for the
                        benefit of Member together with interest at 120% of the
                        applicable federal rate provided for in Section
                        7872(f)(2) of the Code, compounded semiannually.

                               (d)   Notwithstanding anything in this Agreement
                        to the contrary, if after giving effect to the
                        provisions of Section 11(a)-(c) any portion of any
                        payments to Member by the Corporation hereunder would
                        not be deductible by the Corporation for Federal income
                        tax purposes by reason of application of Section 162(m)
                        of the Code, then payment of that portion to Member
                        shall be deferred until the earliest date upon which
                        payment thereof can be made to Member without being
                        non-deductible pursuant to Section 162(m) of the Code.
                        In the event of a such a deferral, the Corporation
                        shall pay interest to Member on the amount deferred at
                        120% of the applicable





                                      -5-

                        federal rate provided for in Section 7872(f)(2) of the 
                        Code, compounded semiannually.

         2.      COBRA Benefits.  In the event of the termination of employment
of Employee without Cause (if initiated by the Corporation) or for Good Reason
(if initiated by Employee), the Corporation will provide a benefit under the
Consolidated Omnibus Budget Reconciliation Act of 1986 ("COBRA") and Section
4980B of the Internal Revenue Code of 1986, as amended, as follows:  the
Corporation shall pay the percentage of the cost of COBRA coverage with respect
to Employee's coverage status (e.g., individual or family) in effect
immediately prior to such termination of employment, which percentage shall be
the fraction (expressed as a percentage), the numerator of which shall be the
difference between (i) the monthly cost of COBRA coverage for Employee's
coverage status in effect immediately prior to the Employment Termination Date
and (ii) Employee's monthly contribution toward Employee's coverage in effect
immediately prior to the Employment Termination Date, and the denominator of
which shall be the monthly cost of COBRA coverage for Employee's coverage
status in effect immediately prior to the Employment Termination Date.  All of
such amounts shall be determined as of the day immediately preceding the
termination of Employee's employment.  The insurance continuation benefits paid
for hereunder shall be deemed to be part of Employee's COBRA coverage.  Such
benefits shall be in addition to any other benefits relating to health or
medical care benefits that, under the Corporation's policies, are available to
Employee following termination of employment.

         IN WITNESS WHEREOF, this Agreement has been made as of the date set
forth above.

                                   AGREEMENT


          THIS AGREEMENT is made as of November 7, 1994 by and between
Puritan-Bennett Corporation, a Delaware corporation (hereinafter referred to as
the "Corporation"), and John H. Morrow (hereinafter referred to as the
"Employee").

          WHEREAS, the Corporation has adopted the Puritan-Bennett Corporation
Supplemental Retirement Benefit Plan effective as of September 1, 1985 (the
"Plan"), which provides benefits that supplement benefits provided under the
Restated Puritan-Bennett Pension Plan (the "Pension Plan"); and

          WHEREAS, the Corporation and the Employee have entered into an
agreement pursuant to which the Employee became a Member under the terms of the
Plan; and

          WHEREAS, the Employee and the Corporation desire to make the
following changes to the Plan as it applies to Employee.

          NOW, THEREFORE, in consideration of the mutual covenants set forth
herein, the Employee and the Corporation agree that, solely for purposes of
determining the Employee's and his beneficiaries' rights under the Plan and not
for purposes of determining the rights of any other individual under the Plan,
the terms of the Plan applicable to Employee shall be amended as follows:

          A.       Section 4, "Retirement Benefits," shall be amended by the
addition of the following new Section 4.04.

                   Section 4.04-Exceptions for Certain Terminations of
          Employment.  Notwithstanding the foregoing provisions of this Section
          4 or any other provision(s) of this Plan, in the event of the
          termination of employment of a Member for Good Reason (if initiated
          by the Member), and/or other than for Cause (if initiated by the
          Corporation), then (a) even if the Member has not at the date of
          termination of employment attained age fifty-five (55) and/or
          completed seven (7) Years of Participation, he shall nevertheless be
          entitled to the Supplemental Monthly Retirement Benefit provided
          under Section 4.01 hereof; (b) the Member shall be deemed to have
          completed ten or more Years of Service and to be 100% vested in the
          Supplemental Monthly Retirement Benefit pursuant to Section 4.01(b)
          hereof; (c) the Member shall be deemed to have been age sixty-five
          (65) (unless his actual age shall be greater) at the date of
          termination of employment so as to be entitled to 100% of the
          Supplemental Monthly Retirement Benefit (as adjusted by Section
          4.01(a)) pursuant to Section 4.01(c); and (d) the Benefit
          Commencement Date under Section 4.02 shall be the first day of the
          calendar month coinciding with or next following the earlier of--(i)
          the first date following termination of Member's employment on which
          the Corporation is in material breach of its obligations pursuant to
          the contracts between the Member and the Corporation dated June 9,
          1994, and November 7, 1994 (the "Contracts"); or





<PAGE>   2
          (ii) the later of:  (I) the date the Member attains age fifty-five
          (55), or (II) the latest date on which the last payment pursuant to
          the Contracts is scheduled to be made (which date shall be determined
          without regard to whether the payment is in fact made prior to such
          scheduled date).

                   For the purposes of this Section 4.04, the terms Cause and
          Good Reason shall be defined as follows:

                   (a)     Cause.  "Cause" means (i) the Member's willful
                           violation of any reasonable rule or direct order of
                           the Corporation's board of directors (the "Board")
                           or the Corporation's Chief Executive Officer
                           ("CEO"), which, after written notice to do so, the
                           Member fails to make reasonable efforts to correct
                           within a reasonable time, or (ii) conviction of a
                           crime, or entry of a plea of nolo contendere with
                           regard to a crime, involving actual moral turpitude
                           or dishonesty of or by the Member, or (iii) drug or
                           alcohol abuse on Corporation premises or at a
                           Corporation sponsored event, or (iv) the Member's
                           material violation of any provision of his
                           employment agreement with the Corporation, which,
                           after written notice to do so, the Member fails to

          Supplemental Monthly Retirement Benefits under this Plan, the Member
          shall not directly or indirectly become or serve as an officer,

          which, in the judgment of the Committee, competes with the Employer,
          unless the Member shall have obtained the prior written consent of
          the Committee.

          IN WITNESS WHEREOF, this Agreement has been made as of the date set

LETTER TO OUR STOCKHOLDERS

    The company recorded charges of $4.6 million for obligations associated
with Thermo Electron Corp.'s unsolicited tender offer resulting in a reported
loss of $640,000 or $.05 per share for the third quarter ending October 31,
1994. Without the charge, earnings per share for the quarter would have been
$.31 per share, up 15% from the $.27 per share (adjusted to eliminate losses
associated with the FOxS blood gas monitoring system) for the same period last
year.

    Orders of $83,018,000 and revenues of $83,412,000 for the quarter were up
11% over the same period last year. For the first nine months, orders of
$245,271,000 and revenues of $247,813,000 were up 7% and 8%, respectively, over
the same period last year.

    The company also was told by Homedco Group, Inc., one of the nation's
leading providers of home respiratory services, that Puritan-Bennett will be
selected as one of its endorsed vendors for home oxygen equipment. Homedco has
been in the process of upgrading its oxygen therapy technology to achieve
greater operational efficiencies. This announcement is the result of Homedco's
formal bid process, and will be one of the largest purchases of oxygen therapy
equipment in Homedco's history.

    In addition, Homedco said it would work with the company to adapt
Puritan-Bennett's CliniVision(R) Respiratory Care Management Information System
to the homecare respiratory management needs of its patients.

SUPPLEMENTAL PRO-FORMA INFORMATION:

    In order to help our stockholders better understand the economic dynamics
and potential of the company's business, we have decided to begin providing
supplemental information that sets forth the company's earnings before
interest, taxes and other unusual charges (EBITOC) in its two main lines of
business - Puritan and Bennett. Unusual charges include any historical
restructuring or current Thermo Electron-related charges. The supplemental
information also excludes discontinued lines of business. Supplemental
pro-forma information dollars are reported in thousands.

    PURITAN - Puritan includes our rapidly growing homecare product lines as
well as our medical gas and gas-related equipment and spirometry product lines.
Aero Systems is also included because it shares one of our larger manufacturing
facilities with the Puritan Group and is relatively small.

    Revenue for the first nine months grew to $159,391 from $136,263 on a FY95
to FY94 comparison, up 17%. Third quarter FY95 revenues are also up, $56,187
compared to $45,751, for the third quarter of FY94. Puritan now accounts for
about two-thirds of the company's total revenues. Puritan revenue for FY94 was
also up from FY93, $184,239 versus $167,763. The average annual growth for the
five years ended January 31, 1994 was 15%. Within Puritan, homecare products
continue to grow at rates considerably above the overall Puritan average.

    Puritan's EBITOC was $16,306 (10% of revenue) and $18,493 (14% of revenue)
for the first nine months of FY95 and FY94, respectively. For the third quarter
of this year, EBITOC was $5,995 (11% of revenue) versus $6,251 (14% of revenue)
in the third quarter FY94. EBITOC was $22,939 (12% of revenue) and $24,740 (15%
of revenue) in FY94 and FY93, respectively. EBITOC has been higher in the
recent past and we expect it to return to those higher levels in the future, as
we realize the benefits of several major regulatory control and compliance
initiatives undertaken in the latter part of FY94 and during FY95. These
initiatives required considerable staffing and other resource additions as well
as manufacturing process modifications. As a result, we experienced certain
significant short-run operating disruptions and inefficiencies, which increased
our costs.

    BENNETT - The Bennett line of business consists of our critical care
ventilator business - a business that continues to represent an exceptional and
long-standing customer franchise on a global basis - as well as our CliniVision
product line in the U.S., and our holter monitoring and portable ventilator
product lines.

    Since FY93, revenues have declined for several reasons including difficult
market conditions, particularly in the U.S. hospital market, discontinuance of
certain older products and accessories as a result of evolving regulatory
standards, and our withdrawal from the U.S. portable ventilator market. In
addition, Bennett has also undertaken major regulatory control and compliance
initiatives at significant cost. Third quarter FY95 and FY94 revenues were
$27,225 and $28,838. For the first nine months of FY95 and FY94, revenues were
$88,422 and $90,361, respectively. FY94 revenues were $122,751 and FY93
revenues were $131,279.

    On a quarter-to-quarter comparison, EBITOC was $456 for the third quarter
of FY95 versus a loss of $793 for the same period of FY94. EBITOC was $2,620
and $2,718 for the first nine months of FY95 and FY94, respectively (3% of
revenues for both periods). FY94 EBITOC was $14 compared to FY93 EBITOC of
$11,803 (9% of revenue). Current and recent EBITOC is not close to where we
believe it should and will be. We believe the recent poor profitability of
Bennett will begin to reverse itself and both revenues and margins will
<PAGE>   2
increase as a result of the benefits from full implementation of our regulatory
compliance initiatives, continued growth of CliniVision and service revenue and
several other positive developments. These developments include the new
products/product enhancements recently cleared by FDA for marketing in the U.S.
and recently introduced internationally. In addition, other important new
products are being developed for introductions a little over a year from now.

    In summary, we are encouraged by the continued strong growth of Puritan in
the third quarter and believe both Puritan and Bennett are well positioned to
begin returning to historical levels of profitability. We will continue to
build upon our unique franchise in the critical care ventilator area while
continuing to invest in and grow the exciting homecare businesses that make up
the bulk of our Puritan business line.
