                     Re: Registration Statement on Form S-3

Ladies and Gentlemen:

     In connection with the filing with the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act"), of a Registration
Statement on Form S-3 (the "Registration Statement"), relating to the public
offering by Baxter International Inc., a Delaware Corporation (the "Company"),
organized under the General Corporation Law of the State of Delaware (the
"Law"), of up to $1,000,000,000 in the aggregate of (i) shares of common stock
of the Company, $1 par value per share (the "Common Stock"), (ii) debt
securities of the Company (the "Debt Securities") to be issued pursuant to an
Indenture (the "Indenture"), dated as of April 26, 2002, between the Company and
the trustee named in the prospectus pertaining to the offering of any such debt
securities (the "Trustee"), (iii) shares of preferred stock of the Company (the
"Preferred Stock"), (iv) warrants representing rights to purchase Debt
Securities, Preferred Stock or Common Stock (the "Warrants"), (v) shares of
convertible preferred stock of the Company (the "Convertible Preferred Stock"),
(vi) convertible preferred debt securities of the Company (the "Convertible Debt
Securities"), (vii) equity purchase contracts, representing rights to purchase
common stock or preferred stock or other equity (the "Equity Purchase
Contracts") and (viii) equity purchase units, representing ownership of Equity
Purchase Contracts and Debt Securities, Preferred Stock or debt obligations of
third parties, including U.S. Treasury securities (the "Equity Purchase Units")
(collectively, (i) through (viii) above, the "Offered Securities"), including up
to an additional $70,000,000 aggregate amount of such Offered Securities that
have been previously registered in accordance with Rule 462(b) under the Act, I
have examined such corporate records, certificates and other documents and such
questions of law as I have considered necessary for the purposes of these
opinions.

     On the basis of the above examination, I advise you that, in my opinion:

1.   The Company has been duly incorporated and is an existing corporation in
     good standing under the Law, and the laws of the State of Delaware.

2.   When (i) the terms of the issuance and sale of the Common Stock have been
     duly approved by all necessary action of the board of directors of the
     Company (the "Board of Directors") (or a duly authorized committee
     thereof), so as not to violate any applicable law or result in a default
     under or a breach of any

                                        1



     agreement or instrument binding upon the Company and so as to comply with
     any requirement or restriction imposed by any court or governmental body
     having jurisdiction over the Company and (ii) certificates for the shares
     of Common Stock have been duly executed, authenticated, issued and
     delivered as contemplated by the Registration Statement and any prospectus
     supplement relating thereto, against payment of the consideration fixed
     therefor by the Board of Directors (or a duly authorized committee
     thereof), the Common Stock (including any Common Stock issued upon
     conversion or exchange under the terms of any other of the Offered
     Securities) will be, when issued, duly authorized, validly issued, fully
     paid and non-assessable.

3.   The execution and delivery of the Indenture and the Debt Securities have
     been duly authorized by the Company. The Indenture has been duly executed
     and delivered by the Company and, assuming the Indenture has been duly
     executed and delivered by the Trustee, when the Debt Securities have been
     duly executed, authenticated, issued, delivered and paid for as
     contemplated by the Registration Statement and any prospectus supplement
     relating thereto and in accordance with the Indenture, assuming the terms
     of such Debt Securities have been duly established so as not to violate any
     applicable law or result in a default under or breach of any agreement or
     instrument binding upon the Company and so as to comply with any
     requirement or restriction imposed by any court or governmental body having
     jurisdiction over the Company, the Debt Securities (including any Debt
     Securities issued upon conversion or exchange under the terms of any other
     of the Offered Securities) will be validly issued and will constitute valid
     and binding obligations of the Company enforceable against the Company in
     accordance with their terms, except as may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium or similar laws of
     general applicability relating to or affecting the rights of creditors and
     to general equity principles (whether considered in a proceeding at law or
     in equity).

4.   When (i) the terms of the Preferred Stock and of its issuance and sale have
     been duly established in conformity with the Company's Certificate of
     Incorporation, as amended, and approved by all necessary corporate action
     of the Board of Directors (or a duly authorized committee thereof), so as
     not to violate any applicable law or result in a default under or breach of
     any agreement or instrument binding upon the Company and so as to comply
     with any requirement or restriction imposed by any court or governmental
     body having jurisdiction over the Company, (ii) a Certificate of
     Designation fixing and determining the terms of the Preferred Stock has
     been filed with the Secretary of State of the State of Delaware and (iii)
     the Preferred Stock has been duly issued and sold as contemplated by the
     Registration Statement and any prospectus supplement relating thereto,
     against payment of the consideration fixed therefore by the Board of
     Directors (or a duly authorized committee thereof), the Preferred Stock
     (including any Preferred Stock issued upon conversion or exchange under the

                                        2



     terms of any other of the Offered Securities) will be, when issued, duly
     authorized, validly issued, fully paid and non-assessable.

5.   When (i) the issuance and terms of the Warrants, the terms of the offering
     thereof and related matters have been duly approved by all necessary
     corporate action of the Board of Directors (or a duly authorized committee
     thereof) so as not to violate any applicable law or result in a default
     under or a breach of any agreement or instrument binding upon the Company
     and so as to comply with any requirement or restriction imposed by any
     court or governmental body having jurisdiction over the Company, (ii) the
     warrant agreement or agreements relating to the Warrants have been duly
     authorized and validly executed and delivered by the Company and the

     Securities) will be, when issued, duly authorized and validly issued.
