                         FORM OF SEVERANCE AGREEMENT

Dear

         In view of your position as ____________________________ at
Puritan-Bennett Corporation ("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
   2

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
Employment Termination Date.  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, as follows:
the Company shall pay 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.  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 ________________________________.  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 immediately preceding the date of the
Change of Control.

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)
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:

                                           entity or "group," within the

                                           combined voting power of the

                                           the date hereof, constitute the

                                           shall be, for purposes of this

                                           dissolution of the Company or of the
                                           sale of all or substantially all of

                                           sole discretion determines
                                           constitutes a Change of Control.

                 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

___________________________ 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 the Company's independent auditors which shall
provide detailed supporting calculations both to the Company and Employee
within 15 business days of the Date of





                                       9
   10

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 Company's independent auditors 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
Company's independent auditors, 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
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 Company's independent auditors,
based upon the assertion of a deficiency by the Internal Revenue Service
against Employee or the Company which the Company's independent auditors
believe has a high probability of success, determine that an Overpayment has
been made, any such Overpayment paid or distributed by the Company to or for
the benefit of





                                       10
   11

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 Company's independent auditors, based upon
controlling precedent or other substantial authority, determine 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
