                              EXPLANATORY NOTE

          Pursuant to the Agreement and Plan of Merger dated December 18, 1996
(the "Merger Agreement") among Medarex, Inc. (the "Registrant"), Medarex
Acquisition Corporation, a wholly-owned subsidiary of the Registrant ("Sub"),
and Houston Biotechnology Incorporated ("HBI"), on February 28, 1997 (the
"Effective Date"), Sub was merged with and into HBI, with HBI continuing as a
wholly-owned subsidiary of the Registrant.  Under the terms of the Merger
Agreement, the Registrant agreed, among other things, to assume each option (the
"HBI Options") to purchase shares of HBI common stock, par value $.01 per share
(the "HBI Common Stock") outstanding on the Effective Date under HBI's 1992
Subordinated Stock Option Plan, 1994 Replacement Stock Option Plan and 1994A
Stock Option Plan (the "HBI Plans"), and that each such HBI Option would
thereafter be exercisable for a number of shares of the Registrant's common
stock, par value $.01 per share (the "Common Stock") equal to the number of
shares of HBI Common Stock subject to such HBI Option immediately prior to the
Effective Date multiplied by 0.182, at an exercise price equal to the exercise
price under such HBI Option divided by 0.182.

          Pursuant to the Merger Agreement, the Registrant also agreed to take
all corporate and other action necessary to reserve and make available
sufficient shares of Registrant's Common Stock for issuance upon exercise of all
the assumed HBI Options and to prepare and file with the Securities and Exchange
Commission appropriate registration statements relating to the issuance of such
shares upon exercise of the assumed options.

          This Registration Statement registers sufficient shares of the
Registrant's Common Stock to cover all shares of the Registrant's Common Stock
issuable upon the exercise of the HBI Options outstanding under the HBI Plans on
the Effective Date and assumed by the Registrant pursuant to the Merger.

Item 4.   Description of Securities.
- -------   ------------------------- 

          Not applicable.

Item 5.   Interests of Named Experts and Counsel.
- -------   -------------------------------------- 

          Not applicable.

Item 6.   Indemnification of Directors and Officers.
- -------   ----------------------------------------- 

          Section 14A:3-5 of The New Jersey Business Corporation Act (the
"NJBCA") empowers a New Jersey corporation to indemnify any person who is or was
a director, officer, employee or agent of the indemnifying corporation or of any
constituent corporation absorbed by the indemnifying corporation in a
consolidation or merger and any person who is or was a director, officer,
trustee, employee or agent of any other enterprise, serving as such at the
request of the indemnifying corporation, or of any such constituent corporation,
or legal representative of any such director, officer, trustee, employee or
agent (a "corporate agent"), against his expenses and liabilities incurred in
connection with any proceeding involving the corporate agent, other than a
proceeding by or in the right of the corporation, if (a) such corporate agent
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and (b) with respect to any
criminal proceeding, such corporate agent had no reason to believe that his
conduct was unlawful.  In addition, a corporation may indemnify such corporate
agent against his expenses in connection with any proceeding by or in the right
of the corporation to procure a judgment in its favor which involves such
corporate agent by reason of his having been such corporate agent, if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation.  However, in such proceeding no
indemnification shall be provided in respect of any claim, issue or matter as to
which such corporate agent shall have been adjudged to be liable to the
corporation, unless and only to the extent that the Superior Court of the State
of New Jersey or the court in which such proceeding was brought shall determine
upon application that despite the adjudication of liability, but in view of all
circumstances of the case, such corporate agent is fairly and reasonably
entitled to indemnity for such expenses as the Superior Court or such other
court shall deem proper.

          Under the NJBCA, a corporation shall indemnify a corporate agent
against expenses to the extent that such corporate agent has been successful on
the merits or otherwise in any proceeding referred to above or in defense of any
claim, issue or matter therein.

          The indemnification and advancement of expenses provided by or granted
pursuant to the NJBCA shall not exclude any other rights, including the right to
be indemnified against liabilities and expenses incurred in proceedings by or in
the right of the corporation, to which a corporate agent may be entitled under a
certificate of incorporation, bylaw, agreement, vote of shareholders, or
otherwise; provided that no indemnification shall be made to or on behalf of a
corporate agent if a judgment or other final adjudication adverse to the
corporate agent establishes that his acts or omissions (a) were in breach of his
duty of loyalty to the corporation or its shareholders, (b) were not in good
faith or involved a knowing violation of law or (c) resulted in receipt by the
corporate agent of an improper personal benefit.

          The Restated Certificate of Incorporation, as amended, and Article
XIII of the Registrant's Amended and Restated By-Laws provide for the

Item 9.  Undertakings.
- -------  ------------ 

  The undersigned Registrant hereby undertakes as follows:

  (1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

       (i) To include any prospectus required by Section 10(a)(3) of the
           Securities Act of 1933 (the "Securities Act");

      (ii) To reflect in the prospectus any facts or events arising after the
           effective date of the registration statement (or the most recent 
           post-effective amendment thereof) which, individually or in
           aggregate, represent a fundamental change in the information set
           forth in this registration statement;

     (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in this registration statement
           or any material change to such information in this registration
           statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii)
- --------  -------                                                            
above shall not apply if the information required to be included in a post-
effective amendment by those paragraphs is contained in periodic reports filed
with or furnished to the Securities and Exchange Commission by the Registrant
pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.

  (2)  That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at the time shall be deemed to be the initial bona fide offering
thereof.


                                     II-4
<PAGE>
 
  (3)  To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

  (4)  That, for purposes of determining any liability under the Securities Act,
each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in this registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

  (5)  To deliver or cause to be delivered with the prospectus, to each person
to whom the prospectus is sent or given, the latest annual report to security
holders that is incorporated by reference in the prospectus and furnished
pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the
Exchange Act; and, where interim financial information required to be presented
by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver,
or cause to be delivered to each person to whom the prospectus or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.

  (6)  Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Dear Sirs:

          You have asked for our opinion in connection with a Registration
Statement on Form S-8 to be filed with the Securities and Exchange Commission
for registration pursuant to the Securities Act of 1933, as amended of 151,000
shares of common stock, par value $.01 per share, of Medarex, Inc. (the
"Company") reserved for issuance upon the exercise of options (the "Options")
granted by Houston Biotechnology Incorporated ("HBI") under its 1994 Replacement
Stock Option Plan, 1994A Stock Option Plan and 1992 Subordinated Stock Option
Plan (collectively, the "Plans"). The Options were assumed by the Company under
the terms of a certain Agreement and Plan of Merger dated December 18, 1996 (the
"Merger Agreement") among the Company, Medarex Acquisition Corporation, a 
wholly-owned subsidiary of the Company ("Sub"), and HBI, pursuant to which Sub
was merged with and into HBI with HBI being the surviving corporation and
becoming a wholly-owned subsidiary of the Company.

          We have reviewed the Plans, as amended to date, the Merger Agreement,
and minutes or copies of the corporate proceedings of HBI relating thereto and
minutes or copies of the corporate proceedings relating to the Registration
Statement hereinabove referred to.  Based on the foregoing, it is our opinion
that the shares reserved by the Company, upon issuance upon the exercise of
Options granted under the Plans in accordance with the provisions of the stock
option agreements evidencing such Options, will be validly issued, fully paid
and non-assessable with no personal liability attaching to the ownership thereof
under the laws of the State of New Jersey.

          We understand that a copy of this opinion will be filed as an exhibit
to the Registration Statement and we hereby consent to such filing.
