                      AMENDMENT TO RIGHTS AGREEMENT BETWEEN
                     HEARTPORT, INC. AND FLEET NATIONAL BANK

               THIS AMENDMENT TO RIGHTS AGREEMENT (this "Amendment") is made as
of the 26th day of January, 2001, by and between Heartport, Inc., a Delaware
corporation (the "Company"), and Fleet National Bank (the "Rights Agent").

               WHEREAS, the Company is entering into an Agreement and Plan of
Merger (as the same may be amended from time to time, the "Merger Agreement")
among Johnson & Johnson, a New Jersey corporation ("Parent"), HP Merger Sub,
Inc., a Delaware corporation and wholly owned subsidiary of Parent ("Merger
Sub"), and the Company, providing for transactions pursuant to which, among
other things, Merger Sub will merge with and into the Company (the "Merger"),
and the Company will become a wholly owned subsidiary of Parent and the former
stockholders of the Company will receive shares of Parent Common Stock;

               WHEREAS, in connection with the Merger Agreement, certain
officers, directors and stockholders of the Company are entering into a
Stockholder Agreement (the "Stockholder Agreement") with Parent and are
delivering Affiliate Letters to Parent (the "Affiliate Letters");

               WHEREAS, the Company and the Rights Agent are parties to a Rights
Agreement dated as of April 25, 1996, as amended (the "Rights Agreement"); and

               WHEREAS, the parties desire to amend the Rights Agreement in
connection with the execution and delivery of the Merger Agreement and the
Stockholder Agreement.

               NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements herein set forth, the parties hereby agree as follows:

               1. The definition of "Acquiring Person" set forth in Section 1 of
the Rights Agreement is hereby amended by adding the following sentence to the
end of that definition:

                    "Notwithstanding the foregoing, no person shall be an
                Acquiring Person solely by reason of the execution and delivery
                of (1) the Agreement and Plan of Merger (as the same may be
                amended from time to time, the "Merger Agreement") among Johnson
                & Johnson, a New Jersey corporation ("Parent"), HP Merger Sub,
                Inc., a Delaware corporation and wholly owned subsidiary of
                Parent ("Merger Sub"), and the Company, (2) the Stockholder
                Agreement between Parent and certain officers, directors and
                stockholders of the Company (as the same may be amended from
                time to time, the "Stockholder Agreement") executed in
                connection with the Merger Agreement or (3) the execution of
                Affiliate Letters by certain officers, directors and
                stockholders of the Company, or by reason of the consummation of
                the transactions contemplated by the Merger Agreement and the
                Stockholder Agreement."

               2. The definition of "Final Expiration Date" set forth in Section
1 of the Rights Agreement shall be amended to read in its entirety as follows:

                    "Final Expiration" shall mean the earlier of (1) the
                Effective Time, as that term is defined in the Merger Agreement,
                or (2) April 25, 2006."

               3. The definition of "Shares Acquisition Date" included in
Section 1 of the Rights Agreement shall be amended by adding the following
sentence to the end of such definition:

                                       57

<PAGE>   2
                    "Notwithstanding anything else set forth in this Agreement,
                a Shares Acquisition Date shall not be deemed to have occurred
                solely by reason of the public announcement or public disclosure
                of the execution and delivery of the Merger Agreement or the
                Stockholder Agreement or the consummation of the transactions
                contemplated thereby."

               4. Section 3(a) of the Rights Agreement shall be amended by
adding the following sentence to the end thereof:

                    "Notwithstanding anything else set forth in this Agreement,
                no Distribution Date shall be deemed to have occurred solely by
                reason of the execution and delivery of the Merger Agreement or
                the Stockholder Agreement or the consummation of the
                transactions contemplated thereby."

               5. The Rights Agreement, as amended by this Amendment, shall
remain in full force and effect in accordance with its terms.

               6. This Amendment may be executed in one or more counterparts and
each of such counterparts shall for all purposes be deemed to be an original,
and all such counterparts shall together constitute one and the same instrument.

               IN WITNESS WHEREOF, the parties hereto have caused this Amendment
to be duly executed and attested, all as of the date and years first above
written.
