                            SUPPLEMENTAL AGREEMENT


                               November 7, 1994



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

                          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
   3

Mr. John H. Morrow

                 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
   5

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:
