               "Subsidiary Senior Indenture") to be executed by the
               applicable Subsidiary, Teva and The Bank of New York;
               and (ii) subordinated debt securities (the "Subsidiary
               Subordinated Debt Securities," and together with the
               Subsidiary Senior Debt Securities, the "Subsidiary Debt
               Securities"), guaranteed by Teva, which may be issued
               pursuant to an indenture (each, a "Subsidiary
               Subordinated Indenture," and together with the
               Subsidiary Senior Indentures, the "Subsidiary
               Indentures") to be executed by the applicable Finance
               Subsidiary, Teva and The Bank of New York.

For purposes of the opinions hereinafter expressed, we have examined originals
or copies, certified and otherwise identified to our satisfaction, of such
documents, corporate records, certificates of public officials and other
instruments as we have deemed necessary as a basis for the opinions expressed
herein. Insofar as the opinions expressed herein involve factual matters, we
have relied (without independent factual investigation), to the extent we deemed
proper or necessary, upon certificates of, and other communications with,
officers and employees of the Teva and upon certificates of public officials. We
have also considered such questions of Israeli law as we have deemed relevant
and necessary as a basis for the opinions hereinafter expressed.

In making the examination described above, we have assumed the genuineness of
all signatures, the capacity of natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified, photostatic or facsimile copies and
the authenticity of the originals of such documents.

In connection with the opinions as to enforceability expressed below, such
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, subject to general principles of equity and to limitations on
availability of equitable relief, including specific performance (regardless of
whether such enforceability is considered in a proceeding in equity or at law)
or by an implied covenant of good faith and fair dealing.

In connection with all of the opinions expressed below, we have assumed that, at
or prior to the time of the delivery of any such security, (i) the Board of
Directors of Teva shall have duly established and authorized the terms of such
security and the related indentures and duly authorized the issuance and sale of
such security and such authorization shall not have been modified or rescinded;
(ii) the Registration Statement shall have been declared effective and such
effectiveness shall not have been terminated or rescinded; and (iii) there shall
not have occurred any change in law affecting the validity or enforceability of
such security. We have also assumed that none of the terms of any security to be
established subsequent to the date hereof, nor the issuance and delivery of such
security, nor the compliance by Teva with the terms of such security will
violate any applicable law or will result in a violation of any provision of any
instrument or agreement then binding upon the relevant Company, or any
restriction imposed by any court or governmental body having jurisdiction over
Teva.

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

                                       3



TULCHINSKY-STERN & Co., LAW OFFICES

     1)   The Deposit Agreement, dated as of February 12, 1997, among Teva, The
          Bank of New York as depositary and the holders of ADRs issued
          thereunder (the "Deposit Agreement") has been duly authorized,
          executed and delivered by Teva.

     2)   When the Ordinary Shares are issued in accordance with the assumptions
          above, such Ordinary Shares will be validly issued, fully paid and
          non-assessable.

     3)   When the Teva Indentures have been duly authorized, executed and
          delivered by the parties thereto in accordance with applicable law,
          and when the specific terms of a particular series of Teva Debt
          Securities have been duly authorized and established in accordance
          with the relevant Teva Indenture and such Teva Debt Securities have
          been duly authorized, executed, authenticated, issued and delivered in
          accordance with the relevant Teva Indenture and any applicable
          underwriting or other agreement, such Teva Debt Securities will
          constitute valid and binding obligations of Teva, enforceable against
          Teva in accordance with their terms.

     4)   When the Subsidiary Indentures have been duly authorized, executed and
          delivered by the parties thereto (including Teva as guarantor) in
          accordance with applicable law, and when the specific terms of a
          particular series of Subsidiary Debt Securities have been duly
          authorized and established in accordance with the relevant Subsidiary
          Indenture and such Subsidiary Debt Securities have been duly
          authorized, executed, authenticated, issued and delivered in
          accordance with the relevant Subsidiary Indenture and any applicable
          underwriting or other agreement, Teva's guarantee under each
          Subsidiary Indenture with respect to such Subsidiary Debt Securities
          will constitute valid and binding obligations of Teva, enforceable
          against Teva in accordance with its terms.

     5)   Under the choice of law or conflicts of law doctrines of Israel, a
          court, tribunal or other competent authority sitting in Israel has
          discretion, but should apply to any claim or controversy arising under
          a Teva Indenture, Subsidiary Indenture or the Deposit Agreements the
          law of the State of New York, which is the local law governing the
          Teva Indentures, Subsidiary Indentures and the Deposit Agreement,
          designated therein by the parties thereto, provided there are no
          reasons for declaring such designation void on the grounds of public
          policy or as being contrary to Israeli law.

The opinions expressed herein are limited to matters governed by the laws of the
State of Israel, and we express no opinion with respect to the laws of any other
country, state or jurisdiction.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. By giving our consent, we do not admit that we are in
the category of persons whose consent is required under Section 7 of the Act or
the rules and regulations promulgated thereunder.

This opinion is being delivered to you solely for your information in connection
with the above matter. This letter addresses matters only as of the date hereof,
may not be relied upon in any manner by any other person and is not to be used,
circulated, quoted or otherwise referred to for any other purpose without our
