         In view of your position as Executive Vice President and Chief
Operating Officer 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.

                          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

                          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

                          opportunity under the modified plan that is

                          any successor thereto with respect to the three full
                          fiscal years immediately preceding the Employment
                          Termination Date (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 made in equal installments on
                          a semi-monthly basis, and shall be subject to all
                          required withholdings.  The Continued Payment Period
                          shall commence on the Employment Termination Date,
                          and shall be two years if the Employment Termination
                          Date occurs before the first anniversary of this
                          Agreement. The Continued Payment Period applicable
                          hereunder shall be increased by three months on each
                          anniversary of the date of this Agreement which
                          occurs prior to the Employment Termination Date,
                          provided, that the Contineud Payment Period shall not
                          exceed three years.

                          (b)     Within 90 days following the Employment
                          Termination Date, the Company shall pay to you,
                          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.  No
                          other management incentive payment or bonus will be
                          payable with respect to the fiscal year in which the
                          Employment Termination Date occurs.

                          (c)     As soon as practical following the Employment
                          Termination Date, the Company shall will 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      Other Rights.  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 cash payment(s) for:  (a) the value
                          of your earned but unused vacation time as of the
                          Employment Termination Date in accordance with then
                          current Company policy, and (b) the value of your
                          deferred compensation account in accordance with your
                          then current payment election.

         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.

                 during the Continued Payment Period under Section 3.1, 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 as of the
                 Employment Termination Date, 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.

         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,
