         This certifies that _______________ or registered assigns, is the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the Rights
Agreement, dated as of June 11, 1991, as amended on September 1, 1992, and as
amended and restated on March 8, 1996, and as such agreement may be further
amended from time to time (the "Rights Agreement"), between Nellcor Puritan
Bennett Incorporated, a Delaware corporation (the "Company), and The First
National Bank of Boston (the "Rights Agent"), to purchase from the Company at
any time after the Distribution Date (as such term is defined in the Rights
Agreement) and prior to 5:00 P.M., Boston time, on March 8, 2006 at the office
of the Rights Agent designated for such purpose, or at the office of its
successor as Rights Agent, one one-hundredth of a fully paid non-assessable
share of Series A Junior Participating Preferred Stock, par value $.001 per
share (the "Preferred Shares"), of the Company, at a purchase price of $320 per
one one-hundredth of a Preferred Share (the "Purchase Price"), upon presentation
and surrender of this Right Certificate with the Form of Election to Purchase
duly executed.

         As provided in the Rights Agreement, the Purchase Price and the number
of one one-hundredths of a Preferred Share which may be purchased upon the
exercise of the Rights evidenced by this Right Certificate are subject to
modification and adjustment upon the happening of certain events.

         This Right Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, as amended from time to time, which terms,
provisions and conditions are hereby incorporated herein by reference and made a
part hereof and to which Rights Agreement reference is hereby made for a full
description of the rights, limitations of rights, obligations, duties and
immunities hereunder of the Rights Agent, the Company and the holders of the
Right Certificates. Copies of the Rights Agreement are on file at the principal
executive offices of the Company and the above-mentioned offices of the Rights

         This Right Certificate, with or without other Right Certificates, upon
surrender at the office of the Rights Agent designated for such purpose, may be
exchanged for another Right Certificate or Right Certificates of like tenor and
date evidencing Rights entitling the holder to purchase a like aggregate number
of Preferred Shares as the Rights evidenced by the Right Certificate or Right
Certificates surrendered shall have entitled such holder to purchase. If this
Right Certificate shall be exercised in part, the holder shall be entitled to
receive upon surrender hereof another Right Certificate or Right Certificates
for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Right Certificate (i) may be redeemed by the Company at a redemption
price of $.001 per Right or (ii) may be exchanged in whole or in part for shares
of the Company's Common Stock or Preferred Shares, par value $.001 per share.

         No fractional Preferred Shares will be issued upon the exercise of any
Right or Rights evidenced hereby (other than fractions which are integral
multiples of one one-hundredth of a Preferred Share, which may, at the election
of the Company, be evidenced by depositary receipts), but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement.

         No holder of this Right Certificate, as such, shall be entitled to vote
or receive dividends or be deemed for any purpose the holder of the Preferred
Shares or of any other securities of the Company which may at any time be
issuable on the exercise hereof, nor shall anything contained in the Rights
Agreement or herein be construed to confer upon the holder hereof, as such, any
of the rights of a stockholder of the Company or any right to vote for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this Right
Certificate shall have been exercised as provided in the Rights Agreement.
   3

purpose until it shall have been countersigned by the Rights Agent.
