Terms and expressions defined or referred to in the Registration Statement and
the forms of the Teva Finance II BV Indentures and the Teva Finance III BV
Indentures, which are not otherwise defined herein, shall have the same meaning
herein.

We have also examined originals or copies of the following corporate documents
of the Company:

          effect as at the date hereof (together the "Articles of
          Incorporation");

     (b)  an extract from the registration of each of the BVs with the
          Commercial Register of the Chamber of Commerce and Industry at
          Curacao, each dated December 11, 2003;

     (c)  resolutions of the Board of Managing Directors of each of the BVs,
          both dated December 10, 2003 (the "Resolutions"), authorizing the
          authorizing the execution, delivery of the Registration Statement by
          the BVs; and

     (d)  a Power of Attorney dated December 11, 2003, issued for and on behalf
          of each of the BVs in favor of Steven Melkman, Th. J. Andriessen and
          William A. Fletcher and each of them (the "Powers of Attorney").

In our examination of the documents referred to above and in expressing our
opinion, we have assumed without independent verification of any kind:

     (1)  the genuineness of all signatures on all documents we have reviewed;

     (2)  the authenticity of all such documents submitted to us as originals;

     (3)  the conformity with the originals of all documents submitted to us as
          copies;

     (4)  that the Teva Finance II BV Indentures and the Teva Finance III BV
          Indentures will constitute the legal, valid and binding obligations of
          the parties thereto other than the BVs, enforceable against the said
          parties in accordance with their respective terms;

     (5)  that the Teva Finance II BV Indentures and the Teva Finance III BV
          Indentures will be legal, valid, binding and enforceable under the
          laws under which they are expressed to be construed and by which they
          are expressed to be governed; and

     (6)  that the Resolutions and the Powers of Attorney have not been revoked
          or amended in any way.

As to any facts material to the opinions expressed herein which were not
independently established or verified, we have relied upon written or oral
statements and representations of officers and other representatives of the
Company. Any reference in this opinion to our "knowledge", "awareness" or the
equivalent, means the conscious awareness of facts or other information by any
lawyer of Zeven & Associates that gave attention to the matters addressed in
this opinion, and does not include constructive notice of matters in public
records, among other things.

In rendering the following opinion, we are opining on the matters hereinafter
referred to, only insofar as they are governed by the laws of the Netherlands
Antilles as currently in effect and applied by the courts of the Netherlands
Antilles. We have made no investigation of and express no opinion in relation to
the laws of any jurisdiction other than the Netherlands Antilles.

Based on and subject to the foregoing, we are of the opinion that:

     1)   Each of the BVs is a limited liability company in the form of a
          "besloten vennootschap" duly organized and existing under the laws of
          the Netherlands Antilles and has all requisite corporate power and
          authority to own its properties and to conduct its business as
          described in the Registration Statement and as set forth in the
          purpose clause (Article 2) of their respective articles of
          incorporation. Each of the BVs has been duly registered with the
          Chamber of Commerce and Industry at Curacao, Netherlands Antilles.

     2)   When the Teva Finance II BV Indentures have been duly authorized,
          executed and delivered by the parties thereto in accordance with the
          forms thereof that we have reviewed, and when the specific terms of a
          particular series of Teva Finance II BV Debt Securities have been duly
          authorized and established in accordance with the relevant Teva
          Finance II BV Indenture and such Teva Finance II BV Debt Securities
          have been duly authorized, executed, authenticated, issued and
          delivered in accordance with the relevant Teva Finance II BV Indenture
          and any applicable underwriting or other agreement, such Teva Finance
          II BV Debt Securities will constitute valid and binding obligations of
          Teva Finance II BV, enforceable against Teva Finance II BV in
          accordance with their terms provided, that the specific terms of the
          relevant particular series of Teva Finance II BV Debt Securities do
          not violate mandatory provisions of Netherlands Antilles law and the
          Articles of Incorporation.

     3)   When the Teva Finance III BV Indentures have been duly authorized,
          executed and delivered by the parties thereto in accordance with the
          forms thereof that we have reviewed, and when the specific terms of a
          particular series of Teva Finance III BV Debt Securities have been
          duly authorized and established in accordance with the relevant Teva
          Finance III BV Indenture and such Teva Finance III BV Debt Securities
          have been duly authorized, executed, authenticated, issued and
          delivered in accordance with the relevant Teva Finance III BV
          Indenture and any applicable underwriting or other agreement, such
          Teva Finance III BV Debt Securities will constitute valid and binding
          obligations of Teva Finance III BV, enforceable against Teva Finance
          III BV in accordance with its terms provided, that the specific terms
          of the relevant particular series of Teva Finance III BV Debt
          Securities do not violate mandatory provisions of Netherlands Antilles
          law and the Articles of Incorporation.

     4)   A competent Netherlands Antilles Court would respect the non-exclusive
          irrevocable submission by Teva Finance II BV and/or Teva Finance III
          BV to the jurisdiction of any of federal or state courts sitting in
          the State of New York regarding any matter arising out of or in
          relation to the obligations of Teva Finance II BV and Teva Finance III
          BV under the Teva Finance II BV Indentures and Teva Finance III BV
          Indentures, respectively, and such submission is binding upon Teva
          Finance II BV and Teva Finance III BV, respectively.

     5)   The United States and the Netherlands Antilles do not currently have a
          treaty providing for reciprocal recognition and enforcement of
          judgments in civil and commercial matters. Therefore, a final judgment
          for the payment of money rendered by any federal or state court in the
          United States based on civil liability, whether or not predicated
          solely upon the federal securities laws of the United States, would
          not be directly enforceable in the Netherlands Antilles.

          If the party in whose favor such a final judgment is rendered brings a
          new suit in a competent court in the Netherlands Antilles, that party
          may submit to the Netherlands Antilles court the final judgment that
          has been rendered in the United States. Since the laws of the State of
          New York have been chosen to govern the Teva Finance II BV Indentures
          and the Teva Finance III BV Indentures, Teva Finance II BV and Teva
          Finance III BV have in their free will submitted to the jurisdiction
          of the federal or state courts sitting in the State of New York in
          connection with disputes relating to the Teva Finance II BV Indentures
          and Teva Finance III BV Indentures, and to the Teva Finance II BV Debt
          Securities and Teva Finance III BV Debt Securities, respectively. The
          holders, by acquiring the Teva Finance II BV Debt Securities or Teva
          Finance III BV Debt Securities, have voluntarily accepted such choice
          of law and choice of forum. A judgment obtained in any such court will
          be considered and recognized by the competent courts of the
          Netherlands Antilles to be part of the Teva Finance II BV Debt
          Securities and Teva Finance III BV Debt Securities, and such courts
          would grant a judgment in accordance with a United States judgment
          that would be enforceable in the

     Netherlands Antilles generally, without any re-examination of the merits of
     the original judgment; provided that:

          .    the judgment is final in the jurisdiction where rendered and was
               issued by a competent court;

          .    the judgment is valid in the jurisdiction where rendered;

          .    the judgment was issued following personal service of the summons
               upon the defendant or its agent and, in accordance with due
               process of law, an opportunity was provided for the defendant to
               defend against the foreign action;

          .    the judgment does not violate any compulsory provisions of
               Netherlands Antilles law or principles of public policy;

          .    the terms and conditions of the Teva Finance II BV Debt
               Securities, Teva Finance III BV Debt Securities, Teva Finance II
               BV Indentures and Teva Finance III BV Indentures, as applicable,
               do not violate any compulsory provisions of Netherlands Antilles
               law or principles of public policy; and

          .    the judgment is not contrary to a prior or simultaneous judgment
               of a competent Netherlands Antilles court.

     Accordingly, there is doubt as to the enforceability in the Netherlands
     Antilles courts of judgments obtained in United States courts. Moreover,
     there is doubt as to the ability of a holder of Teva Finance II BV Debt
     Securities or Teva Finance III BV Debt Securities to bring an original
     action in the Netherlands Antilles predicated on the United States federal
     securities laws.

The opinions set forth above are subject to the qualification that

     (a)  the Teva Finance II BV Debt Securities and Teva Finance III BV Debt
          Securities are issued in denominations of at least US$ 100,000.00, or,
          in the alternative, apply for a license from the Central Bank of the
          Netherlands Antilles and be supervised by the Central Bank of the
          Netherlands Antilles; and

     (b)  the BVs will be required to file for publishing with the Commercial
          Register of the Chamber of Commerce and Industry a certificate setting
          forth the particulars of the relevant Teva Finance II BV Debt
          Securities and Teva Finance III BV Debt Securities, a failure to so
          file such certificate would not affect the validity of the relevant
          Teva Finance II BV Debt Securities and Teva Finance III BV Debt
          Securities or the Registration Statement and the forms of the Teva
          Finance II BV Indentures and the Teva Finance III BV Indentures and
          other than the filing of such certificate, it is not
