  As Representatives of the
  Underwriters named in
  SCHEDULE II hereto

Ladies and Gentlemen:

         Schering-Plough Corporation, a New Jersey corporation (the "COMPANY"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the underwriters named in SCHEDULE II hereto (the "UNDERWRITERS"), for whom
you (the "REPRESENTATIVES") are acting as representatives, an aggregate of
25,000,000 shares of its 6.00% mandatory convertible preferred stock, par value
$1.00 per share (the "PREFERRED STOCK"), convertible into common shares, par
value $0.50 per share (the "COMMON STOCK") of the Company (the "FIRM
SECURITIES") and, at the election of the Underwriters, up to an additional
3,750,000 shares of Preferred Stock (the "OPTIONAL SECURITIES") (the Firm
Securities and the Optional Securities that the Underwriters elect to purchase
pursuant to Section 2 hereof being collectively called the "UNDERWRITTEN
SECURITIES"). The Underwritten Securities will be established by the certificate
of amendment to the certificate of incorporation of the Company identified in
SCHEDULE I hereto (the "CERTIFICATE OF AMENDMENT"). If the firm or firms listed
in SCHEDULE II hereto include only the firm or firms listed in SCHEDULE I hereto
as Representatives, then the terms "Underwriters" and "Representatives", as used
herein, shall each be deemed to refer to such firm or firms.

         The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement on Form S-3 (No. 333-113222) in respect
of certain of the Company's securities (the "SHELF SECURITIES"), and has filed
such amendments thereto as may have been required to the date of this Agreement.
The Company has also filed with, or proposes to file with, the Commission
pursuant to Rule 424 under the Securities Act of 1933, as amended (the "1933
ACT"), a prospectus supplement specifically relating to the Underwritten
Securities. The registration statement, as amended, has been declared effective
by the Commission. Such registration statement, as amended, and the related
prospectus covering the Shelf Securities constituting a part thereof, as from
time to time amended or supplemented





pursuant to the Securities Exchange Act of 1934, as amended (the "1934 ACT"),
the 1933 Act, or otherwise, and including any registration statement filed
pursuant to Rule 462(b) of the 1933 Act, are collectively referred to herein as
the "REGISTRATION STATEMENT" and the "BASIC PROSPECTUS", respectively. The Basic
Prospectus as supplemented by the prospectus supplement (the "PROSPECTUS
SUPPLEMENT") specifically relating to the Underwritten Securities in the form
used to confirm sales of the Underwritten Securities is hereinafter referred to
as the "PROSPECTUS"; PROVIDED, HOWEVER, that all references to the "Registration
Statement" and the "Prospectus" will include all documents incorporated therein
by reference and filed prior to the execution of this Agreement.

         SECTION 1. REPRESENTATIONS AND WARRANTIES.  The Company represents and
warrants to the Representatives and to each Underwriter named in SCHEDULE II
hereto as of the date hereof, as follows:

                (a) The Registration Statement and the Prospectus, at the time
         the Registration Statement became effective and as of the date of this
         Agreement, complied in all material respects with the requirements of
         the 1933 Act and the rules and regulations thereunder (the
         "REGULATIONS"). The Registration Statement, at the time the
         Registration Statement became effective and as of the date of this
         Agreement, did not, and will not, contain any untrue statement of a
         material fact or omit to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading. The
         Prospectus, at the time the Registration Statement became effective and
         as of the date of this Agreement, did not, and will not, contain an
         untrue statement of a material fact or omit to state a material fact
         necessary in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading.
         Notwithstanding the foregoing, the representations and warranties in
         this subsection shall not apply to statements in or omissions from the
         Registration Statement or Prospectus made in reliance upon and in
         conformity with information furnished to the Company in writing by any
         Underwriter through the Representatives expressly for use in the
         Registration Statement or Prospectus.

                (b) The financial statements (as supplemented by the related
         notes and schedules) included in the Registration Statement and
         Prospectus present fairly the financial position of the Company and its
         consolidated subsidiaries on a consolidated basis, as at the dates
         indicated, and the respective results of operations for the periods
         specified therein, and have been prepared in conformity with U.S.
         generally accepted accounting principles applied on a consistent basis
         during the periods involved.

                (c) The documents incorporated by reference in the Prospectus,
         at the time they were or hereafter are filed with the Commission,
         complied or will comply when so filed, as the case may be, in all
         material respects with the requirements of the 1934 Act and the rules
         and regulations thereunder, and, when read together and with the other
         information in the Prospectus, at the time the Registration Statement
         became effective and at the time any amendments thereto become
         effective or hereafter during the period specified in Section 3(b), did
         not and will not contain an untrue statement of a material fact or omit
         to state a material fact required to be stated therein or necessary to
         make the statements therein, in the light of the circumstances under
         which they are made, not misleading.


                                       2





                (d) Since the respective dates as of which information is given
         in the Registration Statement and the Prospectus, except as may
         otherwise be disclosed or incorporated in or contemplated by the
         Registration Statement and Prospectus as of the date of this Agreement:
         (i) there has not been any material adverse change in the financial
         condition, or in the results of operations, of the Company and its
         subsidiaries considered as one enterprise, whether or not arising in
         the ordinary course of business (a "MATERIAL ADVERSE EFFECT") and (ii)
         there have not been any transactions entered into by the Company or its
         subsidiaries not in the ordinary course of business, including
         borrowings for the acquisition of receivables and other operations,
         other than transactions that are not material in relation to the
         Company and its subsidiaries considered as one enterprise.

                (e) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the State

         Statement and has been duly qualified as a foreign corporation for the
         transaction of business and is in good standing under the laws of each
         other jurisdiction in which it owns or leases property, or conducts any
         business, so as to require such qualification, other than where the
         failure to be so qualified or in good standing would not have a
         Material Adverse Effect.

                (f) The execution and delivery of this Agreement, and the
         consummation of the transactions contemplated herein, have been duly
         authorized by all necessary corporate action and will not result in any
         breach of any of the terms, conditions or provisions of, or constitute
         a default under, or result in the creation or imposition of any lien,
         charge or encumbrance upon any property or assets of the Company, as
         applicable, pursuant to the Company's charter or by-laws or any
         indenture, loan agreement, contract or other agreement or instrument to
         which the Company is a party or by which the Company may be bound or to
         which any of the property or assets of the Company is subject, except
         for such breaches, defaults, liens, charges or encumbrances that
         individually or in the aggregate would not reasonably be expected to
         result in a Material Adverse Effect, nor, to its knowledge, will such
         actions result in any material violation of any applicable law, order,
         rule or regulation applicable to the Company of any court or of any
         federal, state or other regulatory authority or other governmental body
         having jurisdiction over the Company, except for such violations that
         individually or in the aggregate would not reasonably be expected to
         result in a Material Adverse Effect, nor will such actions result in
         any violation of the provisions of the charter or by-laws of the
         Company.

                (g) The Company has an authorized capitalization as set forth in
         the Prospectus, and all of the issued shares of capital stock of the
         Company have been duly and validly authorized and issued and are fully
         paid and non-assessable.

                (h) The shares of Common Stock initially issuable upon
         conversion of the Underwritten Securities have been duly and validly
         authorized and reserved for issuance and, when issued and delivered
         upon conversion and in accordance with the provisions of the
         Certificate of Amendment, will be duly and validly issued, fully paid
         and non-assessable and will conform in all material respects to the
         description of the Common Stock contained in the Prospectus.


                                       3





                (i) The Certificate of Amendment creating the Underwritten
         Securities, the proposed form of which has been furnished to the
         Representatives, will have been duly filed with the Secretary of State
         of New Jersey on or before the Firm Closing Time (as defined in Section
         2 hereof).

                (j) The Underwritten Securities have been duly authorized, and,
         when issued and delivered to and paid for by the Underwriters in
         accordance with the provisions of this Agreement, will have been
         validly issued and delivered and will be fully paid and non-assessable;
         and the Underwritten Securities will conform in all material respects
         to the descriptions thereof in the Prospectus.

                (k) No filing with, or authorization, approval, consent,
         license, order, registration, qualification or decree of, any court or
         governmental authority or agency, domestic or foreign, is necessary or
         required for the due authorization, execution and delivery by the
         Company of this Agreement, for the use of proceeds by the Company
         described in the Prospectus, or for the performance by the Company of
         the transactions contemplated by this Agreement, except (1) such as
         have been already made, obtained or rendered, as applicable, (2) as may
         be required under state securities or blue sky laws, (3) as may be
         required by any national securities exchange in connection with listing
         of the Underwritten Securities and Common Stock issuable upon
         conversion of the Underwritten Securities, (4) the filing of the
         Certificate of Amendment with the Secretary of State of New Jersey, or
         (5) as disclosed in or incorporated by reference into the Registration
         Statement or the Prospectus.

                (l) Except as disclosed in or incorporated by reference into the
         Registration Statement or the Prospectus, there is no action, suit,
         proceeding, inquiry or investigation before or brought by any court or
         governmental agency or body, domestic or foreign, now pending, or to

         affecting the Company or any of its subsidiaries that is required to be
         disclosed in the Registration Statement and the Prospectus (other than
         as stated therein), or that would reasonably be expected to result in a
         Material Adverse Effect, or that would reasonably be expected to
         materially and adversely affect the consummation of the transactions
         contemplated under this Agreement or the performance by the Company of
         its obligations hereunder. Except for such proceedings, investigations
         and claims disclosed in or incorporated by reference into the
         Registration Statement or the Prospectus, the aggregate of all pending
         legal or governmental proceedings to which the Company or any of its
         subsidiaries is a party or of which any of their respective assets,
         properties or operations is the subject would not reasonably be
         expected to result in a Material Adverse Effect.

                (n) The Company is not, and upon issuance and sale of the
         Underwritten Securities as herein contemplated and the application of
         the net proceeds therefrom as described in the Prospectus will not be,
         an "investment company" within the meaning of the Investment Company
         Act of 1940, as amended (the "1940 ACT").


                                       4





         Any certificate signed by any officer of the Company and delivered to
the Representatives or counsel for the Underwriters in connection with an
offering of Underwritten Securities shall be deemed a representation and
warranty by the Company, as to the matters covered thereby and as of the date of
such certificate, to each Underwriter participating in such offering.

         SECTION 2. PURCHASE AND SALE.  The Company hereby agrees with the
Underwriters as follows:

                (a) Subject to the terms and conditions herein set forth, (i)
         the Company agrees to issue and sell the Underwritten Securities to the
         several Underwriters as hereinafter provided, and each Underwriter
         agrees to purchase, severally and not jointly, from the Company the
         number of shares of Firm Securities set forth opposite such
         Underwriter's name in SCHEDULE II hereto at the purchase price set
         forth in SCHEDULE I hereto and (ii) in the event and to the extent that
         the Underwriters shall exercise the election to purchase Optional
         Shares as provided below, the Company agrees to issue and sell to each
         of the Underwriters, and each of the Underwriters agrees, severally and
         not jointly, to purchase from the Company up to 3,750,000 Optional
         Securities, at the purchase price per share set forth in clause (i) of
         this subsection (a), less an amount per share equal to any dividends or
         distributions declared by the Company and payable on the Firm
         Securities but not on the Optional Securities. If the option is
         exercised as to all or any portion of the Optional Securities, each of
         the Underwriters, acting severally and not jointly, will purchase that
         portion of the total number of Optional Securities then being purchased
         which the number of Firm Securities set forth in Schedule II opposite
         the name of such Underwriter bears to the total number of Firm
         Securities, subject in each case to such adjustments as the
         Representatives, in their discretion, shall make to eliminate any sales
         or purchases of fractional shares.

                (b) In addition, the Company hereby grants to the Underwriters
         the right to purchase at their election up to 3,750,000 Optional
         Securities, at the purchase price per share set forth in subsection
         (a)(i) above, for the sole purpose of covering sales of shares in
         excess of the number of Firm Securities, provided that the purchase
         price per Optional Security shall be reduced by an amount per share
         equal to any dividends or distributions declared by the Company and
         payable on the Firm Securities but not payable on the Optional
         Securities.  Such election, if any, to purchase Optional Securities may
         be exercised no more than three times and only by written notice from
         the Representatives to the Company, given within a period of 30
         calendar days after the date of this Agreement, setting forth the
         aggregate number of Optional Securities to be purchased and the date on
         which such Optional Securities are to be delivered, as determined by
         the Representatives but in no event earlier than the Firm Closing Time
         (as defined below) or, unless the Representatives and the Company
         otherwise agree in writing, earlier than two or later than ten Business
         Days (as defined below) after the date of such notice.

         Payment of the purchase price for, and delivery of, any Firm Securities
to be purchased by the Underwriters shall be made at the office of Shearman &
Sterling LLP, 599 Lexington Avenue, New York, New York 10022, or at such other
place as shall be agreed upon by the Representatives and the Company, at 9:00
A.M., New York City time, on the third business day


                                       5





(unless postponed in accordance with the provisions of Section 10) following
the date of this Agreement or such other time as shall be agreed upon by the
Representatives and the Company (each such time and date being referred to as
the "FIRM CLOSING TIME"). Payment for the Optional Securities shall be made on
the date specified by the Representatives in the written notice given by the
Representatives of the Underwriters' election to purchase such Optional
Securities, or such other time and date as the Representatives and the Company
may agree upon in writing. Such time and date for payment of the purchase price
for, and delivery of the Optional Securities, if not the Firm Closing Time, is
herein called the "OPTION CLOSING TIME", and each such time and date for payment
of the purchase price for, and delivery with respect to, the Underwritten
Securities is referred to herein as a "CLOSING TIME". As used herein, the term
"BUSINESS DAY" means any day other than a Saturday, a Sunday or a legal holiday
or a day on which banking institutions or trust companies are permitted or
required by law to be closed in The City of New York. Unless otherwise specified
in this Agreement, payment shall be made to the Company by wire transfer of
immediately available funds to such account(s) as the Company may designate in
writing against delivery to the Representatives for the respective accounts of
the Underwriters of the Underwritten Securities to be purchased by them. The
Underwritten Securities or the certificates therefor shall be in such
denominations and registered in such names as the Representatives may request in
writing at least two business days prior to the applicable Closing Time. The
Underwritten Securities will be made available for examination and packaging by
the Representatives on or before the first business day prior to Closing Time.

         SECTION 3. COVENANTS OF THE COMPANY. The Company covenants with the
Representatives, and with each Underwriter participating in the offering of
Underwritten Securities, as follows:

                (a) The Company will promptly transmit copies of the Prospectus
         to the Commission for filing pursuant to Rule 424 of the Regulations
         and will furnish to the Underwriters named therein as many copies of
         the Prospectus as the Representatives shall reasonably request.

                (b) If, at any time when the Prospectus is required by the 1933
         Act to be delivered in connection with sales of the Underwritten
         Securities, any event shall occur or condition exist as a result of
         which it is necessary to further amend or supplement the Prospectus in
         order that the Prospectus will not include an untrue statement of a
         material fact or omit to state any material fact necessary to make the
         statements therein not misleading in the light of circumstances
         existing at the time it is delivered to a purchaser or if it shall be
         necessary at any such time to amend or supplement the Registration
         Statement or the Prospectus in order to comply with the requirements of
         the 1933 Act or the Regulations, the Company will promptly prepare and
         file with the Commission such amendment or supplement, whether by
         filing documents pursuant to the 1934 Act or otherwise, as may be
         necessary so that such statements will not, in the light of the
         circumstances at the time the Prospectus is so required to be
         delivered, be misleading or so that the Registration Statement and
         Prospectus comply with such requirements.

                (c) With respect to the sale of Underwritten Securities, the
         Company will make generally available to its security holders as soon
         as practicable, but not later than 90 days after the close of the
         period covered thereby, earning statements (in form complying with


                                       6





         the provisions of Rule 158, or any applicable successor rule, under the
         1933 Act) covering 12-month periods beginning, in each case, not later
         than the first day of the Company's fiscal quarter next following the
         "effective date" (as defined in Rule 158) of the Registration Statement
         relating to Underwritten Securities.

                (d) At any time when the Prospectus is required by the 1933 Act
         to be delivered in connection with sales of the Underwritten
         Securities, the Company will give the Representatives notice of its
         intention to file any amendment to the Registration Statement or any
         amendment or supplement to the Prospectus, whether pursuant to the 1934
         Act, the 1933 Act or otherwise, and will furnish the Representatives
         with copies of any such amendment or supplement or other documents
         proposed to be filed a reasonable time in advance of filing.

                (e) At any time when the Prospectus is required by the 1933 Act
         to be delivered in connection with sales of the Underwritten
         Securities, the Company will notify the Representatives promptly of (i)
         the effectiveness of any amendment to the Registration Statement, (ii)
         the mailing or the delivery to the Commission for filing of any
         supplement to the Prospectus or any document to be filed pursuant to
         the 1934 Act, (iii) the receipt of any comments from the Commission
         with respect to the Registration Statement, the Prospectus or any
         supplement to the Prospectus, (iv) any request by the Commission for
         any amendment to the Registration Statement or any amendment or
         supplement to the Prospectus or for additional information, and (v) the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or the initiation of any
         proceedings for that purpose. The Company will make every commercially
         reasonable effort to prevent the issuance of any stop order and, if any
         stop order is issued, to promptly obtain the lifting thereof.

                (f) During the period specified in (b) above, the Company will
         deliver to the Representatives as many signed and conformed copies of
         the Registration Statement (as originally filed) and of each amendment
         thereto (including exhibits filed therewith or incorporated by
         reference therein and documents incorporated by reference in the
         Prospectus) as the Representatives may reasonably request, and in each
         case as soon as practicable.

                (g) The Company will endeavor in good faith to qualify the
         Underwritten Securities for offer and sale under the applicable
         securities laws of such jurisdictions as the Representatives may
         reasonably designate; PROVIDED, HOWEVER, that the Company shall not be
         obligated to file any general consent to service or to qualify as a
         foreign corporation or as a dealer in securities in any jurisdiction in
         which it is not so qualified or to subject itself to taxation in
         respect of doing business in any jurisdiction in which it is not
         otherwise so subject. The Company will maintain such qualifications in
         effect for as long as may be reasonably required for the distribution
         of the Underwritten Securities, provided, however, that the Company
         shall not be obligated to file any general consent to service or to
         qualify as a foreign corporation or as a dealer in securities in any
         jurisdiction in which it is not so qualified or to subject itself to
         taxation in respect of doing business in any jurisdiction in which it
         is not otherwise so subject.


                                       7

                                (iv)   Except where the failure to file or to

                        order, registration, qualification or decree,
                        individually or in the aggregate, would not reasonably

                        approval, consent, license, order, registration,
                        qualification or decree of, any court or governmental

                        contemplated under the Prospectus or this Agreement,
                        other than under the 1933 Act and the Regulations, which
                        have already been made, obtained or rendered, as

                        effect to the offering and sale of the Underwritten

                        entity "controlled" by an "investment company", as such
                        terms are defined in the Investment Company Act.

                        Such opinion shall also state that in the course of
                such counsel's review and discussion in connection with the
                preparation of the Registration Statement and Prospectus,
                although such counsel has not independently verified, and is not
                passing upon and assumes no responsibility for, the accuracy,
                completeness or fairness of, or otherwise verified the
                statements made therein, other than as mentioned in (ii) of this
                subsection 4(b)(1), no facts have come to such counsel's
                attention that lead such counsel to believe (x) that the
                Registration Statement or any amendment thereto (except for the
                financial statements and other financial data included therein
                or omitted therefrom, as to which such counsel need not
                comment), at the time the Registration Statement or any such
                amendment became effective, contained an untrue statement of a
                material fact or omitted to state a material fact required to be
                stated therein or necessary to make the statements therein not
                misleading or (y) that the Prospectus (except for the financial
                statements and other financial data included therein or omitted
                therefrom, as to which such counsel need not comment), at the
                time the Prospectus was issued or at the Closing Time, included
                or includes an untrue statement of a material fact or omitted or
                omits to state a material fact necessary in order to make the
                statements therein, in the light of the circumstances under
                which they were made, not misleading.

                           In rendering such opinion, such counsel may rely,
                without independent verification, (A) as to matters involving
                the application of laws of any jurisdiction other than the
                States of Delaware and New York or the Federal laws of the
                United States, to the extent they deem proper and specified in
                such opinion, upon the opinion of other counsel of good standing
                whom they believe to be reliable and who are reasonably
                satisfactory to counsel for the Underwriters; and (B) as to
                matters of fact, to the extent they deem proper, on certificates
                of responsible officers of the Company and public officials.
                Such counsel may further state that their opinion and belief are
                based upon their participation in the preparation of the
                Registration Statement and the Prospectus and any amendments or
                supplements thereto and review and discussion of the contents
                thereof, but are without

                                       10


                independent check or verification except as specified. Such
                opinion may contain customary assumptions, exceptions,
                limitations, qualifications and comments.

                        (2) The opinion, dated as of the applicable Closing
                Time, of the General Counsel or the Vice President, Legal
                Affairs of the Company to the effect that:

                                (i)    The Company is duly qualified to transact
                        business and is in good standing in the states of
                        Arkansas, Georgia, Tennessee and Texas.

                                (ii)   The execution and delivery of this
                        Agreement, the fulfillment of the terms herein and the
                        consummation of the transactions herein contemplated
                        will not conflict with or constitute a breach of, or
                        default under, the charter or by-laws of the Company or,
                        except for such conflicts, breaches or defaults that
                        individually or in the aggregate would not reasonably be
                        expected to result in a Material Adverse Effect, any
                        agreement, indenture or other instrument known to such
                        counsel of which the Company is a party or by which it
                        is bound, or any law, administrative regulation or
                        administrative or court order known to such counsel to
                        be applicable to the Company.

                                (iii)  Except as disclosed in or incorporated by
                        reference into the Registration Statement or the
                        Prospectus, to such counsel's knowledge, there is not
                        pending or threatened any action, suit, proceeding,
                        inquiry or investigation to which the Company or any of
                        its subsidiaries thereof is a party or to which the

                        of its subsidiaries thereof is subject, before or by any
                        court or governmental agency or body, domestic or
                        foreign, which would reasonably be expected to result in
                        a Material Adverse Effect or which would reasonably be
                        expected to materially and adversely affect the
                        consummation of the transactions contemplated under this
                        Agreement, or the performance by the Company of its
                        obligations hereunder.

                                (iv)   The Registration Statement and
                        Prospectus, and each amendment or supplement thereto
                        (except for the financial statements and other financial
                        data included therein or omitted therefrom, as to which
                        such counsel need express no opinion), excluding the
                        documents incorporated by reference therein, as of their
                        respective effective or issue dates, appear on their
                        face to have been appropriately responsive in all
                        material respects to the requirements of the 1933 Act
                        and the Regulations.

                                (v)    The documents incorporated by reference
                        in the Prospectus (except for the financial statements
                        and other financial data included therein or omitted
                        therefrom and the exhibits thereto, as to which such
                        counsel need express no opinion), as of the dates they

                        Such opinion shall also state that in the course of such
                counsel's review and discussion in connection with the
                preparation of the Registration Statement and Prospectus,
                although such counsel has not independently verified, and is not
                passing upon and assumes no responsibility for, the accuracy,
                completeness or fairness of, or otherwise verified the
                statements made or incorporated therein, no facts have come to
                such counsel's attention that lead such counsel to believe (i)
                that the Registration Statement or any amendment thereto (except
                for the financial statements and other financial data included
                therein or omitted therefrom, as to which such counsel need not

                stated therein or necessary to make the statements therein not
                misleading or (ii) that the Prospectus (except for the financial
                statements and other financial data included therein or omitted
                therefrom, as to which such counsel need not comment), at the
                time the Prospectus was issued or at the Closing Time, included
                or includes an untrue statement of a material fact or omitted or
                omits to state a material fact necessary in order to make the
                statements therein, in the light of the circumstances under
                which they were made, not misleading.

                                (v)    The issue and sale of the Underwritten

                        and the consummation of the transactions herein

                        breach of, or default under, the charter or by-laws of
                        the Company or, except for such conflicts, breaches or
                        defaults that individually or in the aggregate would not
                        reasonably be expected to result in a Material Adverse
                        Effect, any law, administrative regulation or
                        administrative or court order known to such counsel to
                        be applicable to the Company.


                                       12





                                (vi)   Except where the failure to file or to
                        obtain such authorization, approval, consent, license,
                        order, registration, qualification or decree,
                        individually or in the aggregate, would not reasonably
                        be expected to result in a Material Adverse Effect or as
                        disclosed in or incorporated by reference into the
                        Registration Statement or Prospectus or as required
                        under state securities or blue sky laws or as may be
                        required by any national securities exchange in
                        connection with listing of the Underwritten Securities
                        and the Common Stock issuable upon conversion of the
                        Underwritten Securities or the filing of the Certificate
                        of Amendment with the Secretary of State of New Jersey,
                        no filing with, or authorization, approval, consent,
                        license, order, registration, qualification or decree
                        of, any court or governmental authority or agency,
                        domestic or foreign, is necessary or required for the
                        due authorization, execution or delivery by the Company
                        of this Agreement or for the performance by the Company
                        of the transactions contemplated under the Prospectus,
                        this Agreement, and the Certificate of Amendment, other
                        than under the 1933 Act and the Regulations.

                                (vii)   The Company has an authorized
                        capitalization as set forth in the Prospectus, and the
                        shares of Common Stock initially issuable upon
                        conversion of the Underwritten Securities have been duly
                        and validly authorized and reserved for issuance and,
                        when issued and delivered in accordance with the
                        provisions of the Certificate of Amendment, will be duly
                        and validly issued and fully paid and non-assessable.

                                (viii)  The statements set forth in the
                        Prospectus under the caption "Description of Mandatory
                        Convertible Preferred Stock" and "Description of Capital
                        Stock" and in the Registration Statement in Item 15,
                        insofar as such statements constitute a summary of the
                        terms of the Preferred Stock, the Common Stock, the
                        Certificate of Amendment, the Company's certificate of
                        incorporation, as amended, and the New Jersey Business
                        Corporation Act, as amended, have been reviewed by such
                        counsel and fairly summarize the matters described
                        therein in all material respects.

                        Such opinion may contain customary assumptions,
                exceptions, limitations, qualifications and comments.

                        (4) The favorable opinion, dated as of the applicable
                Closing Time, of Shearman & Sterling LLP, counsel for the
                Underwriters, with respect to the matters as the Representatives
                may reasonably request.

                (c) At the applicable Closing Time, there shall not have been,
         since the date of this Agreement or since the respective dates as of
         which information is given in the Registration Statement, any Material
         Adverse Effect or any development that would likely result in a
         prospective material adverse change in the financial condition, or in
         the results of operations, of the Company and its subsidiaries
         considered as one enterprise, whether or not arising in the ordinary
         course of business, and the Representatives shall


                                       13





         have received a certificate of the President or a Vice President of the
         Company, dated as of such Closing Time, to the effect that there has
         been no such Material Adverse Effect or any development that would
         likely result in a prospective material adverse change in the financial
         condition, or in the results of operations, of the Company and its
         subsidiaries considered as one enterprise, whether or not arising in
         the ordinary course of business, and to the effect that the other
         representations and warranties of the Company contained in Section 1
         are true and correct with the same force and effect as if made on and
         as of the Closing Time.

                (d) The Representatives shall have received from Deloitte &
         Touche LLP or other independent certified public accountants acceptable
         to the Representatives a letter, dated as of the date of this Agreement
         and delivered at such time, in form heretofore agreed to containing
         statements and information of the type ordinarily included in
         accountants' "comfort letters" to underwriters with respect to the
         financial statements and certain financial information contained or
         incorporated by reference into the Registration Statement and the
         Prospectus.

                (e) The Representatives shall have received from Deloitte &
         Touche LLP or other independent certified public accountants acceptable
         to the Representatives a letter, dated as of the applicable Closing
         Time, reconfirming or updating the letter required by subsection (d) of
         this Section to the extent that may be reasonably requested by the
         Representatives.

                (f) At the applicable Closing Time, counsel for the Underwriters
         shall have been furnished with such documents as they may reasonably
         require for the purpose of enabling them to pass upon the issuance and
         sale of the Underwritten Securities as herein contemplated and related
         proceedings.

                (g) The Company shall have obtained and delivered to the
         Underwriters executed copies of the agreement attached hereto as
         EXHIBIT A from the directors and officers listed on SCHEDULE III
         hereto.

         If any condition specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be terminated
by the Representatives by notice to the Company at any time on or prior to the
applicable Closing Time, and such termination shall be without liability of any
party to any other party except as provided in Section 5.

         SECTION 5. PAYMENT OF EXPENSES. The Company will pay all expenses
incident to the performance of its obligations under this Agreement, including
(i) the printing and filing of the Registration Statement and all amendments
thereto, (ii) the preparation, issuance and delivery of the Underwritten
Securities to the Underwriters and the shares of Common Stock issuable upon
conversion of the Underwritten Securities to the holders of such Underwritten
Securities, (iii) the fees and disbursements of the Company's counsel and
accountants, (iv) the qualification of the Underwritten Securities under
securities laws in accordance with the provisions of Section 3(g), including
filing fees and the fees and disbursements of counsel for the Underwriters in
connection therewith and in connection with the preparation of any Blue Sky
Surveys and Legal Investment Surveys, (v) the printing and delivery to the
Underwriters in quantities as


                                       14





hereinabove stated of copies of the Registration Statement and any amendments
thereto, and of the Prospectus and any amendments or supplements thereto, (vi)
the printing and delivery to the Underwriters of copies this Agreement, any Blue
Sky Surveys and Legal Investment Surveys, (vii) the fees, if any, of rating
agencies for rating the Underwritten Securities, (viii) the costs and expenses
related to any filing with any national securities exchange, (ix) the costs and
expenses incident to the preparation of the Certificate of Amendment and the
filing of the Certificate of Amendment with the Secretary of State of New
Jersey, (x) any expenses incurred by the Company in connection with a "road
show" presentation to potential investors, (xi) the cost and charges of any
transfer agent and (xii) the fees and expenses, if any, incurred in connection
with the listing of the Underwritten Securities on any national securities
exchange.

         If this Agreement is terminated by the Representatives in accordance
with the provisions of Section 4 or Section 9(i), the Company shall reimburse
the Underwriters named on SCHEDULE II hereto for all of their reasonable
out-of-pocket expenses, including the reasonable fees and disbursements of
counsel for the Underwriters.

         SECTION 6. INDEMNIFICATION. (a) The Company agrees to indemnify and
hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act as follows:

                (i)                 against any and all loss, liability, claim,
        damage and expense whatsoever arising out of any untrue statement or
        alleged untrue statement of a material fact contained in the
        Registration Statement (or any amendment thereto), or any omission or
        alleged omission therefrom, of a material fact required to be stated
        therein or necessary to make the statements therein, in the light of the
        circumstances under which they were made, not misleading, or arising out
        of any untrue statement or alleged untrue statement of a material fact
        contained in any preliminary prospectus related to the Prospectus or the
        Prospectus (or any amendment or supplement thereto), or the omission or
        alleged omission therefrom, of a material fact necessary in order to
        make the statements therein, in the light of the circumstances under
        which they were made, not misleading, unless such untrue statement or
        omission or such alleged untrue statement or omission was made in
        reliance upon and in conformity with written information furnished to
        the Company by or on behalf of any Underwriter through the
        Representatives expressly for use in the Registration Statement (or any
        amendment thereto), any preliminary prospectus related to the Prospectus
        or the Prospectus (or any amendment or supplement thereto);

                (ii)                against any and all loss, liability, claim,
        damage and expense whatsoever to the extent of the aggregate amount paid
        in settlement of any litigation, or any investigation or proceeding by
        any governmental agency or body, commenced or threatened, or of any
        claim whatsoever based upon any such untrue statement or omission, or
        any such alleged untrue statement or omission, if such settlement is
        effected with the prior written consent of the Company; and

                (iii)               against any and all expense whatsoever
        reasonably incurred in investigating, preparing or defending against any
        litigation, or any investigation or proceeding by any governmental
        agency or body, commenced or threatened, or any claim


                                       15





                whatsoever based upon any such untrue statement or omission, or
                any such alleged untrue statement or omission, to the extent
                that any such expense is not paid under (i) or (ii) above;

PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made based upon
written information furnished to the Company by any Underwriter through the
Representatives, expressly for use in the Registration Statement (or any
amendment thereto), or any preliminary prospectus related to the Prospectus or
the Prospectus (or any amendment or supplement thereto) and PROVIDED FURTHER
that the foregoing indemnity agreement with respect to any preliminary
prospectus related to the Prospectus shall not inure to the benefit of any
Underwriter from whom the person asserting any such losses, claims, damages or
liabilities purchased Underwritten Securities, or any person controlling any
Underwriter, if a copy of the Prospectus (as then amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) was not sent
or given by or on behalf of such Underwriter to such person, if required by law
so to have been delivered, within a reasonable period of time prior to the
written confirmation of the sale of the Underwritten Securities to such person,
and if the Prospectus (as so amended or supplemented) would have cured the
defect giving rise to such losses, claims, damages or liabilities, unless such
failure is the result of noncompliance by the Company with Sections 3(a) and
3(f) hereof.

                (b) Each Underwriter severally agrees that it will indemnify and
hold harmless the Company and each of its officers who signs the Registration
Statement and each of its directors and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act to the same extent as the foregoing indemnity from the Company, but
only with respect to statements or omissions made in any preliminary prospectus
related to the Prospectus, the Prospectus (or any amendment or supplement
thereto) or the Registration Statement (or any amendment thereto) in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of such Underwriter through the Representatives expressly for use in
the Registration Statement (or any amendment thereto), any preliminary
prospectus related to the Prospectus or the Prospectus (or any amendment or
supplement thereto). In case any action shall be brought against the Company or
any person so indemnified based on the Registration Statement (or any amendment
thereto), any preliminary prospectus related to the Prospectus or the Prospectus
(or any amendment or supplement thereto) and in respect of which indemnity may
be sought against any Underwriter, such Underwriter shall have the rights and
duties given to the Company, and the Company and each person so indemnified
shall have the rights and duties given to the Underwriters, by the provisions of
subsection (a) of this Section.

                (c) Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent the indemnifying party is not materially
prejudiced as a result thereof and in any event shall not relieve it from any
liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified pursuant to Section 6(a) above,
counsel to the indemnified parties shall be selected by the Representatives,
and, in the case of parties indemnified pursuant to Section 6(b) above,


                                       16





counsel to the indemnified parties shall be selected by the Company. An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying parties be liable for fees
and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent (which consent will
not be unreasonably withheld) of the indemnified parties, settle or compromise
or consent to the entry of any judgment with respect to any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution could be sought under this Section 6 or Section 7 hereof (whether
or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

         SECTION 7. CONTRIBUTION. If the indemnification provisions provided in
Section 6 above should under applicable law be unavailable to an indemnified
party or insufficient in respect of any losses, liabilities, claims, damages or
expenses (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, liabilities, claims, damages or
expenses (or actions in respect thereof) (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Underwriters on the other hand from the offering of the
Underwritten Securities or (ii) if the allocation in clause (i) is not permitted
by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) but also the relative fault of the
Company on the one hand and the Underwriters on the other hand in connection
with the statements or omissions which resulted in such losses, liabilities,
claims, damages or expenses (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative benefits received by the
Company on the one hand and the Underwriters on the other hand shall be deemed
to be in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company and the total underwriting discounts
and commissions received by the Underwriters, in each case as set forth on the
cover of the Prospectus, bear to the aggregate public offering price of the
Underwritten Securities as set forth on such cover. The relative fault shall be
determined by reference to, among other things, whether the indemnified party
failed to give the notice required under Section 6 above including the
consequences of such failure, and whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission of the Company and the
Underwriters, directly or through the Representatives of the Underwriters. The
Company and the Underwriters agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable
considerations referred to above in this Section 7. The amount paid or payable
by an indemnified party as a result of the losses, liabilities, claims,


                                       17





damages or expenses (or actions in respect thereof) referred to above in this
Section 7 shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this Section 7, no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Underwritten Securities underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such Underwriter has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Underwriters' obligations
in this Section 7 to contribute are several in proportion to their respective
underwriting obligations as set forth opposite their respective names in
SCHEDULE II hereto and not joint.

         The obligations of the Company under this Section 7 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act; and the
obligations of the Underwriters under this Section 7 shall be in addition to any
liability which the respective Underwriters may otherwise have and shall extend,
upon the same terms and conditions, to each officer who signs the Registration
Statement and each director of the Company and to each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act.

         SECTION 8. AGREEMENTS TO SURVIVE DELIVERY. All agreements contained in
this Agreement, or contained in certificates of officers of the Company
submitted pursuant hereto, shall remain operative and in full force and effect,
regardless of any termination of this Agreement, or any investigation made by or
on behalf of any Underwriter or controlling person, or by or on behalf of the
Company, and shall survive delivery of any Underwritten Securities to the
Underwriters.

         SECTION 9. TERMINATION. The Representatives may terminate this
Agreement, immediately upon notice to the Company, at any time prior to the
applicable Closing Time (i) if there has been, since the date of this Agreement
or since the respective dates as of which information is given in the
Registration Statement, any Material Adverse Effect or any development that
would likely result in a prospective material adverse change in the financial
condition, or in the results of operations, of the Company and its subsidiaries
considered as one enterprise, whether or not arising in the ordinary course of
business, or (ii) if there has occurred any material adverse change in the
financial markets in the United States or in the international financial
markets, any outbreak of hostilities or escalation thereof or other calamity or
crisis or change or development involving a prospective change in national or
international political, financial or economic conditions, in each case the
effect of which is such as to make it, in the reasonable judgment of the
Representatives, impracticable or inadvisable to market the Underwritten
Securities or enforce contracts for the sale of the Underwritten Securities, or
(iii) if trading on the New York Stock Exchange has been suspended or materially
limited and such suspension or limitation makes it, in the reasonable judgment
of the Representatives, impracticable or inadvisable to market the Underwritten
Securities or enforce contracts for the sale of the Underwritten Securities, or
(iv) if a banking moratorium has been declared by either


                                       18





Federal or New York authorities, or (v) a material disruption has occurred in
commercial banking or securities settlement or clearance services in the United
States. In the event of any such termination, (x) the covenants set forth in
Section 3 with respect to any offering of Underwritten Securities shall remain
in effect so long as any Underwriter retains beneficial ownership of any such
Underwritten Securities purchased from the Company pursuant to this Agreement
and (y) the covenant set forth in Section 3(c) (to the extent there has been a
sale of Underwritten Securities), the provisions of Section 5, the indemnity
agreement set forth in Section 6, the contribution agreement set forth in
Section 7 and the provisions of Sections 8 and 13 shall remain in effect.

         SECTION 10. DEFAULT. If one or more of the Underwriters participating
in an offering of Securities shall fail at the applicable Closing Time to
purchase the Underwritten Securities which it is or they are obligated to
purchase under this Agreement (the "DEFAULTED SECURITIES"), then the
Representatives shall have the right, within 24 hours thereafter, to make
arrangements for one or more of the non-defaulting Underwriters, or any other
underwriters, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth. If, however, during such 24 hours the Representatives shall not have
completed such arrangements for the purchase of all of the Defaulted Securities,
then:

(a)      if the aggregate liquidation preference amount of Defaulted Securities
         does not exceed 10% of the aggregate liquidation preference amount of
         the Underwritten Securities to be purchased pursuant to this Agreement,
         the non-defaulting Underwriters named in SCHEDULE II to this Agreement
         shall be obligated to purchase the full amount thereof in the
         proportions that their respective underwriting obligations thereunder
         bear to the aggregate underwriting obligations of all such
         non-defaulting Underwriters, or

(b)      if the aggregate liquidation preference amount of Defaulted Securities
         exceeds 10% of the aggregate liquidation preference amount of the
         Underwritten Securities to be purchased pursuant to this Agreement and
         arrangements satisfactory to the Representatives and the Company for
         the purchase of such Defaulted Securities are not made within 24 hours
         after such default, this Agreement shall terminate without any
         liability on the part of any non-defaulting Underwriters or the
         Company.

         As used in this Section only, the aggregate amount or aggregate
liquidation preference amount of Underwritten Securities shall mean the
aggregate liquidation preference amount of any Preferred Stock.

         No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

         In the event of a default by any Underwriter or Underwriters as set
forth in this Section, either the Representatives or the Company shall have the
right to postpone the applicable Closing Time for a period ending as soon as
practicable after the original Closing Time, but in any event not exceeding
seven days after the original Closing Time, in order that any required changes,
if any, in the Registration Statement or Prospectus or in any other documents or
arrangements may be effected.


                                       19





         SECTION 11. NOTICES. All notices and other communications hereunder
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication. Notices to the

         Re:  SCHERING-PLOUGH CORPORATION - LOCK-UP AGREEMENT

Ladies and Gentlemen:

         The undersigned understands that you, as representatives (the
"REPRESENTATIVES"), propose to enter into an Underwriting Agreement on behalf of
the several Underwriters named in SCHEDULE II to such agreement (collectively,
the "UNDERWRITERS"), with Schering-Plough Corporation, a New Jersey corporation
(the "COMPANY"), providing for a public offering (the "PUBLIC OFFERING") of the
Mandatory Convertible Preferred Stock, par value $1.00 per share, of the Company
(the "SHARES") pursuant to a Registration Statement on Form S-3 to be filed with
the Securities and Exchange Commission.

         In consideration of the agreement by the Underwriters to offer and sell
the Shares, and of other good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the undersigned agrees that, during
the period beginning from the date of the supplemental Preliminary Prospectus to
be filed in connection with the announcement of commencement of the Public
Offering and continuing to and including the date 90 days after the date of the
final prospectus covering the public offering of the Shares (the "LOCK-UP
PERIOD"), the undersigned will not offer, sell, contract to sell, pledge, grant
any option to purchase, make any short sale or otherwise dispose of any common
shares, par value $0.50 per share, of the Company (the "COMMON STOCK"), or any
options or warrants to purchase any shares of Common Stock of the Company, or
any securities convertible into, exchangeable for or that represent the right to
receive shares of Common Stock of the Company, in each case, whether now
beneficially owned or hereinafter acquired by the undersigned (including holding
as a custodian) (collectively the "UNDERSIGNED'S SHARES").

         The foregoing restriction is expressly agreed to preclude the
undersigned from engaging in any hedging or other transaction which is designed
to or which reasonably could be expected to lead to or result in a sale or
disposition of the Undersigned's Shares even if such Shares would be disposed of
by someone other than the undersigned. Such prohibited hedging or other
transactions would include without limitation any short sale or any purchase,
sale or grant of any right (including without limitation any put or call option)
with respect to any of the Undersigned's





Shares or with respect to any security that includes, relates to, or derives any
significant part of its value from such Shares.

         Notwithstanding the foregoing, the undersigned may transfer the
Undersigned's Shares (i) as a BONA FIDE gift or gifts, provided that the donee
or donees thereof agree to be bound in writing by the restrictions set forth
herein, (ii) to any trust for the direct or indirect benefit of the undersigned
or the immediate family of the undersigned, provided that the trustee of the
trust agrees to be bound in writing by the restrictions set forth herein, and
provided further that any such transfer shall not involve a disposition for
value, (iii) to any corporation, limited liability company, limited partnership
or general partnership of which all of the equity interest is owned by the
undersigned, or the immediate family of the undersigned and/or one or more
trusts, described in clause (ii) above, provided the transferee agrees to be
bound in writing by the restrictions set forth herein, and provided further that
any such transfer shall not involve a disposition for value, (iv) if the
transfer of such Undersigned's Shares occurs by operation of law, such as rules
of intestate succession or statutes governing the effects of a merger, provided
that the transferee agrees to be bound in writing by the restrictions set forth
herein, or (v) with the prior written consent of Goldman, Sachs & Co., Banc of
America Securities LLC and Citigroup Global Markets Inc. For purposes of this
Lock-Up Agreement, "immediate family" shall mean any relationship by blood,
marriage or adoption, not more remote than first cousin. In addition,
notwithstanding the foregoing, if the undersigned is a corporation, partnership,
trust or similar entity, it may transfer the capital stock of the Company to any
wholly-owned subsidiary of such entity, or to its partners, members or
shareholders; PROVIDED, HOWEVER, that in any such case, it shall be a condition
to the transfer that the transferee execute an agreement stating that the
transferee is receiving and holding such capital stock subject to the provisions
of this Agreement and there shall be no further transfer of such capital stock
except in accordance with this Agreement, and provided further that any such
transfer shall not involve a disposition for value. Except as otherwise
disclosed on Exhibit 1 hereto, if any, the undersigned now has, and, except as
contemplated by clause (i), (ii), (iii), (iv) or (v) above, for the duration of
this Lock-Up Agreement will have, good and marketable title to the Undersigned's
Shares, free and clear of all liens, encumbrances, and claims whatsoever. The
undersigned also agrees and consents to the entry of stop transfer instructions
with the Company's transfer agent and registrar against the transfer of the
Undersigned's Shares except in compliance with the foregoing restrictions during
the Lock-Up Period.

         The undersigned understands that the Company and the Underwriters are
relying upon this Lock-Up Agreement in proceeding toward consummation of the
Public Offering. The undersigned further understands that this Lock-Up Agreement
is irrevocable and shall be binding upon the undersigned's heirs, legal
representatives, successors, and assigns. This Lock-Up Agreement shall lapse and
become null and void if the Public Offering is not consummated on or before
September 15, 2004, or, if earlier, the date the Underwriting Agreement (other
than provisions thereof which survive termination) shall terminate or be
terminated for any reason, prior to the payment for and delivery of the Shares.





         This Lock-Up Agreement shall be governed by and construed in accordance
with the laws of the State of New York applicable to agreements made and to be
performed in said State.

                                      Very truly yours,
