            FISCAL AGENCY AGREEMENT, dated as of January 3, 1996 (this
       _Agreement_), between THERMO ELECTRON CORPORATION, a corporation
       duly organized and validly existing under the laws of the State
       of Delaware (the "Company"), and CHEMICAL BANK, a banking
       corporation duly organized and validly existing under the laws of
       the State of New York (the "Fiscal Agent").

            1.   The Securities.

                 (a)  The Company has, by a Subscription Agreement,
       dated November 28, 1995 (the "Subscription Agreement"), among the
       Company and the managers named therein (the "Managers"), agreed
       to issue and sell to the Managers U.S. $500,000,000 aggregate
       principal amount of its 4q% Convertible Subordinated Debentures
       Due 2003 (hereinafter referred to as the "Initial Securities" and
       together with the Over-Allotment Securities (as defined below),
       if any, the "Securities").  In addition, the Company has granted
       an option to the Managers to subscribe for up to an additional
       U.S. $85,000,000 principal amount of Securities (the
       "Over-Allotment Securities") solely to cover over-allotments, if
       any.  The amount of Securities that may be issued hereunder may
       be increased by agreement between the Company and the Fiscal
       Agent, and such additional securities shall be "Securities"
       hereunder.  Interest on the Securities shall be calculated on the
       basis of a 360 day year comprised of twelve 30-day months.

                 (b)  Pursuant to the Subscription Agreement, the
       Managers (or their affiliates) may sell the Securities to (i)
       persons who are not "U.S. Persons" (as such term is defined in
       Regulation S promulgated by the United States Securities and
       Exchange Commission (the "SEC") pursuant to the Securities Act of
       1933, as amended (the "Securities Act")) in transactions that
       meet the requirements of Regulation S, (ii) _qualified
       institutional buyers" (as such term is defined in Rule 144A
       promulgated by the SEC pursuant to the Securities Act and
       hereinafter referred to as "QIBs") in reliance on Rule 144A (the
       Securities that are resold by the Managers pursuant to Rule 144A
       being hereinafter referred to as the "Rule 144A Securities") and
       (iii) a limited number of _institutional accredited investors"
       (within the meaning of Rule 501(a)(1), (2), (3) or (7)
       promulgated by the SEC pursuant to the Securities Act)
       ("Institutional Accredited Investors") that, prior to their
       purchase of any Securities, deliver to the Managers a letter
       containing certain representations and agreements.

                 (c)  A portion of the Securities will initially be
       issued in the form of a temporary global debenture in bearer form
       without coupons or conversion rights, which will be deposited
       with a depository in London for Cedel and Euroclear for the
       accounts of the subscribers of such Securities on the Closing
       Date (as defined herein).  Upon deposit of the temporary global
       debenture, Cedel or Euroclear, as the case may be, will credit
       each subscriber with a principal amount of Securities equal to
PAGE

       the principal amount thereof for which it has subscribed and paid
       in the aggregate principal amount of the entire issue of
       Securities less the aggregate principal amount of the Rule 144A
       Securities and Accredited Investor Securities concurrently
       issued, substantially in the form of Exhibit B hereto (the
       "Regulation S Global Security").  As hereinafter provided, the
       Regulation S Global Security may subsequently be exchanged for
       Securities in printed definitive form either as (i) bearer
       Securities ("Bearer Securities") in denominations of U.S. $1,000
       and U.S. $10,000 and with interest coupons attached thereto,
       representing the semi-annual interest payable thereon, or (ii)
       fully registered Securities ("Registered Regulation S
       Securities") in denominations of U.S. $1,000 and integral
       multiples thereof, without coupons, or (iii) a beneficial
       interest in the Rule 144A Global Security (as defined below), in
       accordance with the provisions of Section 5(c).  Bearer
       Securities shall be substantially in the form of Exhibit A
       hereto, including the coupons set forth therein.  Registered
       Regulation S Securities also shall be substantially in the form
       of Exhibit A hereto.  The Securities which are not Bearer
       Securities or the Regulation S Global Security are hereinafter
       collectively referred to as the "Registered Securities."

                 (d)  The Rule 144A Securities will initially be issued
       in the form of a global Security in the aggregate principal
       amount of the Rule 144A Securities, which Security shall be in
       substantially the form of Exhibit A hereto, and is hereinafter
       referred to as the "Rule 144A Global Security." Such Rule 144A
       Global Security shall be duly executed by the Company and
       authenticated by the Fiscal Agent (as defined below) as
       hereinafter provided and will be deposited on the Closing Date
       with, or on behalf of, The Depositary Trust Company ("DTC") and
       registered in the name of Cede & Co., as nominee of DTC.  The
       aggregate principal amount of the Rule 144A Global Security may
       from time to time be increased or reduced by adjustments made in
       the Security Register.  Transfers of interests in the Rule 144A
       Global Security will be subject to certain restrictions set forth
       therein and described in Section 3 hereof.

                 (e)  The Accredited Investor Securities will initially
       be issued in fully registered form in minimum denominations of
       U.S. $250,000 and integral multiples of U.S. $1,000 in excess
       thereof, which Securities shall be in substantially the form of
       Exhibit A hereto, and are hereinafter collectively referred to as
       "Registered Accredited Investor Securities." Such Registered
       Accredited Investor Securities shall be in definitive, fully
       registered certificated form only and registered in the names of
       such Institutional Accredited Investors or their nominees.  Such
       Institutional Accredited Investors may not elect to hold
       Registered Accredited Investor Securities through DTC, Euroclear
       or Cedel.  The aggregate principal amount of the Registered
       Accredited Investor Securities may be increased or reduced by
       adjustments made in the Security Register.  Transfers of
       Registered Accredited Investor Securities will be subject to
PAGE


       certain restrictions set forth therein and described in Section 3
       hereof.

                 (f)  During the period beginning on the Closing Date
       and ending on the date which is three years (or the then
       applicable holding period under Rule 144(k) under the Securities
       Act (or successor provision)) after the later of the date of
       original issuance thereof and the last date on which the Company
       or any affiliate of the Company was the owner thereof (or any
       predecessor), all Rule 144A Securities, all Accredited Investor
       Securities, all other Registered Securities and all Securities
       issued upon registration of transfer of or in exchange for such
       Securities, shall be "Restricted Securities" and shall be subject
       to the restrictions on transfer in Section 3 hereof; provided,
       however, that the term "Restricted Securities" shall not include
        Registered Securities as to which such restrictions on transfer
       have been terminated in accordance with Section 3(g) hereof.  All
       Restricted Securities shall bear the legend required by Section
       3(f) hereof.

                 (g)  The Securities will be convertible as provided in
       Section 4 of the Registered Securities and the Bearer Securities
       and Section 7 hereof.  The Securities may be redeemed by the
       Company as provided in Section 3 of the Registered Securities and
       the Bearer Securities and Section 6 hereof.  The Securities will
       be subordinated as provided in Section 7 of the Registered
       Securities and the Bearer Securities.  The Registered Securities,
       the Bearer Securities and the Regulation S Global Security shall
       contain such appropriate insertions, omissions, substitutions and
       other variations as are required or permitted by this Agreement
       and may have such letters, numbers or other marks of
       identification and such legends or endorsements placed thereon as
       may, consistent herewith, be determined by the officer of the
       Company executing such Securities, as evidenced by his execution
       of such Securities.

                 (h)  The Company in issuing the Securities shall use
       CUSIP numbers, and the Fiscal Agent may use such CUSIP numbers in
       any notice of redemption with respect to the Securities.  The
       Company shall obtain one CUSIP number for the Rule 144A
       Securities and one for the Registered Regulation S Securities.
       In addition, the Company shall obtain an ISIN number and a Common
       Code for the Regulation S Global Security, the Bearer Securities
       and the Registered Regulation S Securities.

                 (i)  Pursuant to the Subscription Agreement, the
       Managers (or their affiliates) may sell the Securities to persons
       who are not persons within the United States or its possessions
       or "United States persons" as defined in the Internal Revenue
       Code except as provided in U.S. Treasury Regulation Section
       1.163-5 (c) (2) (i) (D).  In compliance with United States tax
       laws and regulations, Bearer Securities may not be offered or
       sold during the 40-day period beginning on the Closing Date, or
       at any time if part of a Manager's unsold allotment, to a person
PAGE


       who is within the United States or to a United States person
       other than (a) foreign branches of United States financial
       institutions if such institutions agree in writing to comply with
       the requirements of Section 165(j)(3)(A), (B), or (C) of the
       Internal Revenue Code of 1986, as amended, and the regulations
       thereunder, (b) United States offices of exempt distributors, or
       (c) United States offices of international organizations or
       foreign central banks.  United States tax laws and regulations
       also require that Bearer Securities not be delivered within the
       United States.

                 (j)  The Company will use its reasonable best efforts
       to have the Securities approved for listing on the Luxembourg
       Stock Exchange or such other exchange as shall be agreed upon by
       the Managers and the Company, as soon as practicable after the
       date hereof.

            3.   Registration of Transfer and Exchange; Restrictions on

       Registered Security at any office or agency designated for such
       purpose by the Company pursuant to Section 12(g) hereof, the
       Company shall execute, and the Fiscal Agent shall authenticate,

       transferees, one or more new Registered Securities of any
       authorized denominations and of a like aggregate principal amount
       and bearing such restrictive legends as may be required by this
       Agreement; provided, however, that, with respect to any
       Registered Security that is a Restricted Security, the Fiscal
       Agent shall not register the transfer of such Security unless the
       conditions in Sections 3(b) hereof shall have been satisfied.
       The holder of each Restricted Security, by such holder's
       acceptance thereof, agrees to be bound by the transfer
       restrictions set forth herein and in the legend on such
       Restricted Security.

                 (b)  Whenever any Restricted Security is presented or
       surrendered for registration of transfer or exchange for a
       Registered Security registered in a name other than that of the
       holder, no registration of transfer or exchange shall be made
       unless:

                 (i)  The registered holder presenting such Restricted
       Security for transfer shall have certified to the Fiscal Agent in
       writing that such registered holder is transferring such
       Restricted Security to a QIB in compliance with the exemption
       from registration under the Securities Act provided by Rule 144A
       thereunder (or a successor provision);

                 (ii) The registered holder presenting such Restricted
       Security for transfer shall have certified to the Fiscal Agent in
PAGE


       writing that the registered holder is transferring such
       Restricted Security outside the United States in a transaction
       meeting the requirements of Rule 904 of Regulation S under the
       Securities Act;

                 (iii)     (A) The registered holder presenting such
       Restricted Security for transfer shall have certified to the
       Fiscal Agent in writing that such registered holder is
       transferring such Restricted Security to an _institutional
       accredited investor" (within the meaning of Rule 501(a)(1), (2),
       (3) or (7) under the Securities Act) in a transaction that is
       exempt from the registration requirements of the Securities Act;
       and (B) a broker or dealer registered under Section 15 of the
       Securities Exchange Act of 1934, as amended, shall have certified
       to the Fiscal Agent in writing that: (x) each person who will
       become a beneficial owner of the Restricted Security upon
       transfer is an institutional "accredited investor" (as such term
       is defined in Rule 501(a)(1), (2), (3) or (7) under the
       Securities Act); (y) no general solicitation or general
       advertising was made or used by such broker or dealer in
       connection with the offer and sale of such Restricted Security to
       such person(s); and (z) such institutional accredited investor
       has been informed that the Securities have not been registered
       under the Securities Act and are subject to the restrictions on
       transfer set forth in the Securities and this Agreement;

                 (iv) The registered holder presenting such Restricted
       Security for transfer shall have certified to the Fiscal Agent in
       writing that the registered holder is transferring the Registered
       Security to the Company; or

                 (v)  The Fiscal Agent has received transfer
       documentation indicating, and a written opinion of U.S. counsel
       acceptable in form and substance to the Company and the Fiscal
       Agent, that the transfer is being made pursuant to an exemption
       from, or a transaction not otherwise subject to, the registration
       requirements of the Securities Act.

                 For purposes of this Section 3(b), any such
       certification to the Fiscal Agent in writing shall be in the form
       of the Transfer Notice set forth on the reverse of such Security.
       In the case of transfer pursuant to the foregoing clauses (ii),
       (iii) or (v) above, the Company and the Fiscal Agent may require
       that the registered holder deliver an opinion of counsel,
       certifications or other information acceptable to them in form
       and substance.  The Fiscal Agent shall notify the Company upon
       receipt of such Transfer Notice and the Company shall immediately
       advise the Fiscal Agent as to whether an opinion of counsel,
       certifications or other information as described herein shall be
       required for such transfer.  In addition, in the case of a
       transfer pursuant to the foregoing clause (iii) above, the
       transferor shall be required to deliver a letter from the
       transferee substantially in the form of Exhibit G hereto.

                 (c)  Bearer Securities may, at the option of the holder
       thereof, (with all unmatured coupons appertaining thereto and
       matured defaulted coupons appertaining thereto), be exchanged at,
       subject to applicable laws and regulations, the offices of the
       paying agencies in London and, if the Securities are listed on
       the Luxembourg Stock Exchange and so long as listed thereon,
       Luxembourg or as designated by the Company for such purposes
       pursuant to Section 12(g), for an equal aggregate principal
       amount of Registered Securities in denominations of $1,000 and
       integral multiples thereof without coupons and/or Bearer
       Securities of authorized denominations.  If such holder is unable
       to produce any such unmatured coupon or coupons or matured coupon
       or coupons in default, such exchange may be effected if the
       Bearer Securities are accompanied by payment in funds acceptable
       to the Company in an amount equal to the face amount of such
       missing coupon or coupons or the surrender of such missing coupon
       or coupons may be waived by the Company if there be furnished to
       it and the Fiscal Agent such security or indemnity as it may
       require to save it, the Fiscal Agent, the Paying Agent and any
       paying agency harmless.  If thereafter the holder of such
       Security shall surrender to any paying agency any such missing
       coupon in respect of which such a payment shall have been made,
       such holder shall be entitled to receive the amount of such
       payment from the Company; provided, however, that, except as
       otherwise provided in the form of Bearer Security set forth in
       Exhibit A hereto, interest represented by coupons shall be
       payable only upon presentation and surrender of those coupons
       outside of the United States, its territories and its
       possessions.  Bearer Securities and coupons are transferable upon
       delivery.

                 Registered Securities may, at the option of the holder
       thereof, be exchanged at the Corporate Trust Office of the Fiscal
       Agent in New York City, or subject to applicable laws and
       regulations, the offices of the paying agencies in London and, if
       the Securities are listed on the Luxembourg Stock Exchange and so
       long as listed thereon, Luxembourg or as designated by the
       Company for such purposes pursuant to Section 12(g), for an equal
       aggregate principal amount of Registered Securities of different
       denominations.  Registered Securities shall not be exchangeable
       for Bearer Securities.  Whenever any Registered Securities are so
       surrendered for exchange, the Company shall execute, and the
       Fiscal Agent shall authenticate and deliver, the Registered
       Securities which the holder making the exchange is entitled to
       receive.  If the Registered Security so surrendered for exchange
       is a Registered Accredited Investor Security and the holder
       thereof requests in writing that such Registered Accredited
       Investor Security be exchanged for an interest in the Rule 144A
       Global Security, such Registered Accredited Investor Security
       will be exchangeable into an equal aggregate principal amount of
       beneficial interest in the Rule 144A Global Security; provided,
       however, that, if such Registered Accredited Investor Security is
       a Restricted Security, such exchange may only be made if such
       holder certifies to the Fiscal Agent in writing that such holder
PAGE


       is a QIB by completing the Transfer Notice on the reverse of such
       Security.  Upon any exchange as provided in the immediately
       preceding sentence, the Fiscal Agent shall cancel such Registered
       Accredited Investor Security and cause, or direct any custodian
       for the Rule 144A Global Security to cause, in accordance with
       the standing instructions and procedures existing between the
       Depository and any such custodian, the aggregate principal amount
       of Securities represented by the Rule 144A Global Security to be
       increased accordingly.  If no Rule 144A Global Securities are
       then outstanding, the Company shall issue and the Fiscal Agent
       shall authenticate a new Rule 144A Global Security in the
       appropriate principal amount.

                 Any person having a beneficial interest in a Rule 144A
       Global Security may upon request exchange such beneficial
       interest for a Registered Security only as provided in this
       paragraph.  Upon receipt by the Company and the Fiscal Agent of
       (i) written or electronic instructions from the Depository or its
       nominee (or such other form of instructions as is customary) on
       behalf of any person having a beneficial interest in a Rule 144A
       Global Security and upon receipt by the Fiscal Agent of a written
       order of such person containing registration instructions and
       (ii) in the case of a Restricted Security, the following
       additional information and documents (all of which may be
       submitted by facsimile):

                      (A)  if such beneficial interest is being
       transferred to the person designated as being the beneficial
       owner, a certification to that effect from such person; or

                      (B)  if such beneficial interest is being
       transferred to a person other than the person designated as being
       the beneficial owner, the provisions of Section 3(b) hereof have
       been satisfied;

       in which case the Fiscal Agent or any custodian for the Rule 144A
       Global Security, at the direction of the Fiscal Agent, shall, in
       accordance with the standing instructions and procedures existing
       between the Depository and such custodian, cause the aggregate
       principal amount of the Rule 144A Global Security to be reduced
       accordingly and, following such reduction, the Company shall
       execute and the Fiscal Agent shall authenticate and deliver to
       such person or the transferee, as the case may be, a Registered
       Security in the appropriate principal amount and, if such
       Registered Security is a Restricted Security, including the
       appropriate legend.  Registered Securities issued in exchange for
       a beneficial interest in the Rule 144A Global Security pursuant
       to this paragraph shall be registered in such names and such
       authorized denominations as shall be instructed to the Fiscal
       Agent.  The Fiscal Agent shall deliver such Registered Securities
       to the persons in whose names such Securities are so registered.

                 (d)  Notwithstanding any other provision of this
       Agreement (other than the provisions set forth in Section 3(e)
PAGE


       hereof), the Rule 144A Global Security may not be transferred as
       a whole except by the Depository to a nominee of the Depository
       or by a nominee of the Depository to the Depository or another
       nominee of the Depository or by the Depository or any such
       nominee to a successor Depository or a nominee of such successor
       Depository.

                 (e)  If at any time either (i) the Depository for the
       Rule 144A Global Security notifies the Company that the
       Depository is unwilling or unable to continue as Depository for
       the Rule 144A Global Security and a successor Depository for the
       Rule 144A Global Security is not appointed by the Company within
       90 days after delivery of such notice, or (ii) the Company, at
       its sole discretion, notifies the Fiscal Agent in writing that it
       elects to cause the issuance of Registered Securities under this
       Agreement, then the Company shall execute, and the Fiscal Agent
       shall authenticate and deliver, Registered Securities in an
       aggregate principal amount equal to the principal amount of the
       Rule 144A Global Security in exchange for such Rule 144A Global
       Security.

                 (f)  Each certificate evidencing Restricted Securities
       shall bear a legend in substantially the following form:

            THIS SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED
       UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE
       "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND NEITHER THIS
       SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED,
       SOLD OR OTHERWISE TRANSFERRED WITHIN THE "UNITED STATES" OR TO
       "U.S. PERSONS" (AS DEFINED IN REGULATION S UNDER THE SECURITIES
       ACT) IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE
       EXEMPTION THEREFROM.  EACH PURCHASER OF THIS SECURITY IS HEREBY
       NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE
       PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE
       144A THEREUNDER.  THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE
       HEREOF, REPRESENTS, ACKNOWLEDGES AND AGREES FOR THE BENEFIT OF
       THE COMPANY THAT: (I) IT HAS ACQUIRED A "RESTRICTED" SECURITY
       WHICH HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT; (II) IT
       WILL NOT OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY PRIOR TO
       THE DATE WHICH IS THREE YEARS (OR THE THEN APPLICABLE HOLDING
       PERIOD UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR SUCCESSOR
       PROVISION))AFTER THE DATE OF ORIGINAL ISSUANCE HEREOF AND THE
       LAST DATE ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY
       WAS THE OWNER OF SUCH RESTRICTED SECURITIES (OR ANY PREDECESSOR),
       EXCEPT (A) TO THE COMPANY, (B) PURSUANT TO A REGISTRATION
       STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES
       ACT, (C) FOR SO LONG AS THIS SECURITY IS ELIGIBLE FOR RESALE
       PURSUANT TO RULE 144A, TO A PERSON WHO THE SELLER REASONABLY
       BELIEVES IS A _QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE
       144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE
       REQUIREMENTS OF RULE 144A, (D) OUTSIDE THE UNITED STATES IN A
       TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE
       SECURITIES ACT OR (E) PURSUANT TO ANOTHER AVAILABLE EXEMPTION
       FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND, IN
PAGE


       EACH CASE, IN ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF
       ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE
       JURISDICTION; AND (III) IT WILL, AND EACH SUBSEQUENT HOLDER IS
       REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THIS SECURITY OF THE
       RESALE RESTRICTIONS SET FORTH IN (II) ABOVE.  ANY OFFER, SALE OR
       OTHER DISPOSITION PURSUANT TO THE FOREGOING CLAUSE (II)(D) AND
       (E) IS SUBJECT TO THE RIGHT OF THE ISSUER OF THIS SECURITY AND
       THE FISCAL AGENT FOR SUCH ISSUER TO REQUIRE THE DELIVERY OF AN
       OPINION OF COUNSEL, CERTIFICATIONS OR OTHER INFORMATION
       ACCEPTABLE TO THEM IN FORM AND SUBSTANCE.

                 (g)  The restrictions imposed by Section 3(b) upon the
       transferability of any particular Restricted Security shall cease
       and terminate when such Restricted Security has been sold
       pursuant to an effective registration statement under the
       Securities Act or transferred pursuant to Rule 144 under the
       Securities Act (or any successor provision thereto), unless the
       holder is an affiliate of the Company within the meaning of said
       Rule 144 (or such successor provision).  Any Restricted Security
       as to which such restrictions on transfer shall have expired in
       accordance with their terms or shall have terminated may, upon
       surrender of such Restricted Security for exchange to the Fiscal
       Agent in accordance with the provisions of this Section 3(g)
       (accompanied, in the event that such restrictions on transfer
       have terminated by reason of a transfer pursuant to Rule 144 (or
       any successor provision), by an opinion of counsel reasonably
       acceptable to the Company, addressed to the Company and the
       Fiscal Agent and in form and scope satisfactory to the Company,
       to the effect that the transfer of such Restricted Security has
       been made in compliance with Rule 144 (or such successor
       provision)), be exchanged for a new Registered Security, of like
       tenor and aggregate principal amount, which shall not bear the
       restrictive legend required by Section 3(f) hereof.  The Company
       shall promptly inform the Fiscal Agent in writing of the
       effective date of any registration statement registering the
       Securities under the Securities Act.

                 (h)  The transfer and exchange of the Rule 144A Global
       Security or beneficial interests therein shall be effected
       through the Depository, in accordance with this Agreement and the
       procedures of the Depository therefor, which shall include
       restrictions on transfer comparable to those set forth herein to
       the extent required by the Securities Act.

                 (i)  At such time as all beneficial interests in the
       Rule 144A Global Security have either been exchanged for
       Registered Securities, redeemed, repurchased or cancelled, the
       Rule 144A Global Security shall be returned to or retained and
       cancelled by the Fiscal Agent.  At any time prior to such
       cancellation, if any beneficial interest in the Rule 144A Global
       Security is exchanged for Registered Securities, redeemed,
       repurchased or cancelled, the principal amount of Securities
       represented by the Rule 144A Global Security shall be reduced
       accordingly and an endorsement shall be made on the Rule 144A
PAGE


       Global Security, by the Fiscal Agent or any custodian therefor,
       at the direction of the Fiscal Agent, to reflect such reduction.

                 (j)  All Securities issued upon any registration of
       transfer or exchange of Securities shall be the valid obligations
       of the Company, evidencing the same obligations, and entitled to
       the same benefits under this Agreement, as the Securities
       surrendered upon such registration of transfer or exchange.

                 (k)  Every Registered Security presented for
       registration of transfer or surrendered for exchange shall be
       duly endorsed, or be accompanied by a written instrument of
       transfer in form satisfactory to the Company, the Fiscal Agent
       and the Transfer Agent to which such Security is presented or
       surrendered and the Security Registrar, duly executed by the
       holder thereof or his attorney duly authorized in writing.  All
       such instruments shall comply with the applicable provisions of
       this Section 3. The registration of the transfer of a Registered
       Security by the Security Registrar shall be deemed to be the
       written acknowledgment of such transfer on behalf of the Company.

                 (1)  No service charge shall be made for any
       registration of transfer or exchange (other than the cost of
       delivery), but the Company or the Transfer Agent may require
       payment of a sum sufficient to cover any tax or other
       governmental charge that may be imposed in connection with any
       registration of transfer or exchange of Securities, other than
       exchanges pursuant to Section 4 hereof or not involving any
       registration of transfer.

                 (m)  Neither the Company nor the Fiscal Agent nor any
       of the offices or agencies designated for the purposes specified
       in Section 12(f) nor any Transfer Agent shall be required (i) to
       exchange Bearer Securities for Registered Securities during the
       period between the close of business on any Record Date (as
       defined in Section 5(c) hereof) and the opening of business on
       the next succeeding interest payment date, (ii) to exchange any
       Bearer Security (or portion thereof) for a Registered Security if
       the Company shall determine and inform the Fiscal Agent in
       writing that, as a result thereof, the Company would incur
       adverse consequences under the United States Federal income tax
       laws at the time of such exchange, or (iii) in the event of a
       redemption in part, (A) to register the transfer of Registered
       Securities or to exchange any Bearer Securities for Registered
       Securities for a period of 15 days immediately preceding the date
       notice is given pursuant to Section 3(f) of the Registered
       Securities and the Bearer Securities identifying the serial
       numbers of any Securities to be redeemed, or (B) to register the
       transfer of or exchange of any Registered Security so selected
       for redemption in whole or in part, except portions not being
       redeemed of Securities being redeemed in part, or (C) to exchange
       any Bearer Security called for redemption; provided, however,
       that a Bearer Security called for redemption may be exchanged, on
       the terms and conditions set forth above, for a Registered
PAGE


       Security that is simultaneously surrendered, with written
       instruction for payment on the date fixed for redemption, unless
       the redemption date is after a Record Date and on or before the
       next succeeding interest payment date, in which case such
       exchange may be made only prior to the Record Date immediately
       preceding the redemption date.

            4.   Closing Date; Exchange of Regulation S Global Security.

                 (a)  At any time and from time to time after the
       execution and delivery of this Agreement, the Company may deliver
       Securities executed by the Company in accordance with this
       Agreement to the Fiscal Agent for authentication together with an
       officer's certificate of the Company directing such
       authentication, and the Fiscal Agent shall thereupon authenticate
       and make such Securities available for delivery upon and in
       accordance with the written order of the Company.  No Security
       shall be valid or enforceable for any purpose unless and until
       the certificate of authentication thereon shall have been
       manually signed by a duly authorized signatory of the Fiscal
       Agent and such duly executed certificate of authentication on any
       Security shall be conclusive evidence that the Security has been
       duly authenticated and delivered hereunder.  The Regulation S
       Global Security, the Rule 144A Global Security and the Registered
       Accredited Investor Securities will be issued upon payment to the
       Company or its order in United States dollars in same-day funds
       by check or wire transfer to a United States dollar account
       designated by the Company, at 4:00 p.m., London time, on January
       3, 1996, or at such other time on the same or such other date,
       not later than 5:00 p.m., London time, on the fourth Business Day
       (as such term is defined in Section 5(h) hereof) in London
       thereafter, as the Managers and the Company may agree (the
       "Closing Date").  Such payment will be made (1) upon
       authorization from the Managers, (2) against delivery as provided
       in Section 4(b) hereof of the amount, if any, of Rule 144A
       Securities and Registered Accredited Investor Securities as the
       Managers may request and as they shall direct, and (3) against
       delivery of the Regulation S Global Security for the balance of
       the Securities to The Chase Manhattan Bank, N.A., London office,
       as depositary (the "Common Depositary") for Morgan Guaranty Trust
       Company of New York, Brussels office, as operator of the
       Euroclear System (the "Euroclear Operator"), and Cedel Bank
       societe anonyme ("Cedel").  The Regulation S Global Security
       shall be held on deposit with the Common Depositary for the
       accounts of the Euroclear Operator and Cedel, for credit to the
       Managers' respective Securities Clearance Accounts (or to such
       other accounts as the Lead Manager may have specified) with the
       Euroclear Operator or Cedel.

                 (b)  On the Closing Date, the Company shall execute and
       deliver to (i) the Managers, at the office of an affiliate of the
       Lead Manager (as defined in the Subscription Agreement) in New
       York, Registered Accredited Investor Securities (which shall have
       been duly authenticated by the Fiscal Agent and which may be in
PAGE


       typewritten form) in respect of the Accredited Investor
       Securities and (ii) the Depositary, at its office in New York,
       the Rule 144A Global Security (which shall have been duly
       authenticated by the Fiscal Agent and which may be in typewritten
       form) in respect of the Rule 144A Securities.

                 (c)  On or before the Exchange Date, the Company will
       execute and deliver to the Fiscal Agent, at its office in London,
       definitive Registered Regulation S Securities and Bearer
       Securities in the aggregate principal amount outstanding in the
       Regulation S Global Security and in such proportion of Registered
       Regulation S Securities to Bearer Securities as the Fiscal Agent
       may specify.  "Exchange Date" means the date following the
       expiration of the 40-day period commencing on the Closing Date.
       On or after the Exchange Date, the Regulation S Global Security
       may be surrendered to the Fiscal Agent to be exchanged, as a
       whole or in part, for definitive Bearer Securities without
       charge, and the Fiscal Agent shall authenticate and deliver, in
       exchange for such Regulation S Global Security or the portions
       thereof to be exchanged, an equal aggregate principal amount of
       definitive Bearer Securities, but only upon presentation to the
       Fiscal Agent at its office in London of a certificate of the
       Euroclear Operator or Cedel with respect to the Regulation S
       Global Security or portions thereof being exchanged,
       substantially in the form of Exhibit C hereto, to the effect that
       it has received a certificate or certificates in substantially
       the form set forth in Exhibit D hereto dated no earlier than 15
       days prior to the Exchange Date and signed by the person
       appearing in its records as the owner of the Regulation S Global
       Security or portions thereof being exchanged. Similarly, on or
       after the Exchange Date, portions of the Regulation S Global
       Security may be exchanged for an equal aggregate principal amount
       of definitive Registered Regulation S Securities upon
       presentation to the Fiscal Agent of a certificate substantially
       in the form of Exhibit F hereto, to the effect that it has
       received a certificate or certificates in substantially the form
       set forth in Exhibit E hereto dated no earlier than 15 days prior
       to the Exchange Date and signed by the person appearing in its
       records as the owner of the Regulation S Global Security or
       portions thereof being exchanged. In addition, on or after the
       Exchange Date, (or if permitted by the Company and the Fiscal
       Agent, before the Exchange Date), portions of the Regulation S
       Global Security may be exchanged for a beneficial interest in an
       equal aggregate principal amount of the Rule 144A Global Security
       (which portion shall be a Restricted Security) upon
       certifications acceptable to the Company and to the Fiscal Agent
       to the effect that the person(s) beneficially owning such portion
       of the Rule 144A Global Security are QIBs that acquired such
       interest in transaction(s) that complied with the exemption from
       registration under the Securities Act provided by Rule 144A
       thereunder (or a successor provision).

                 (d)  The definitive Securities and coupons shall be
       printed, lithographed or engraved or produced by any combination
PAGE


       of these methods or may be produced in any other manner permitted
       by the rules of any securities exchange on which the Securities
       may be listed, all as determined by the officers executing such
       Securities and coupons, as evidenced by such execution.

                 (e)  Only Bearer Securities may be issued upon receipt
       by the Euroclear Operator or Cedel of a certificate or
       certificates in the form of Exhibit D hereto.  Bearer Securities
       will be delivered only outside the United States, its territories
       or its possessions.  Only Registered Securities may be issued
       upon receipt by the Euroclear Operator or Cedel of a certificate
       or certificates in the form of Exhibit E hereto.

                 (f)  The delivery to the Fiscal Agent by the Euroclear
       Operator or Cedel of any certificate referred to above may be
       relied upon by the Company and the Fiscal Agent as conclusive
       evidence that a corresponding certificate or certificates has or
       have been delivered to the Euroclear Operator or Cedel pursuant
       to the terms of this Agreement.  The Fiscal Agent shall receive
       such certificate on behalf of the Company and shall promptly
       deliver the original certificate to the Company, retaining a copy
       of such certificate for its records.

                 (g)  Upon any such exchange of a portion of the
       Regulation S Global Security for a definitive Bearer Security or
       Securities or a definitive Registered Regulation S Security or
       Securities or a beneficial interest in the Rule 144A Global
       Security, the Regulation S Global Security shall be endorsed by
       the Fiscal Agent to reflect the reduction of its principal amount
       by an amount equal to the aggregate principal amount of such
       definitive Security or Securities.  Until so exchanged in full,
       the Regulation S Global Security shall in all respects be
       entitled to the same benefits under this Agreement as definitive
       Securities authenticated and delivered hereunder.

            5.   Payment.

                 (a)  The Company will pay or cause to be paid to the
       Paying Agent the amounts, at the times and for the purposes, set
       forth herein and in the text of the Securities, and the Company
       hereby authorizes and directs the Paying Agent to make payment of
       the principal of, premium, if any, and interest on and Additional
       Amounts (as defined in Section 2 of the Registered Securities and
       the Bearer Securities), if any, on the Securities from such
       payments.

                 (b)  At least 15 days prior to the date on which any
       payment of Additional Amounts shall be required to be made
       pursuant to Section 2 of the Registered Securities and the Bearer
       Securities, the Company will furnish the Paying Agent, each other
       paying agency of the Company and the Fiscal Agent with a
       certificate of one of its duly authorized officers instructing
       the Paying Agent and each other paying agency of the Company as
       to the amounts required (i) to be deducted or withheld for or on
PAGE

       account of any taxes described in Section 2 of the Registered
       Securities and the Bearer Securities from a payment to be made on
       that date and (ii) to be paid to each holder of Securities or
       coupons as Additional Amounts pursuant to that Section.  If the
       foregoing amounts are not uniform for all holders, then the
       Company's certificate shall specify by country of residence or
       other factor the amounts required to be deducted or withheld and
       to be paid as Additional Amounts for each holder or class of
       holders of the Securities or coupons.  In the absence of its
       receipt of any such  certificate from the Company, the Paying
       Agent may make payment without deduction or withholding.  The
       Company hereby agrees to indemnify the Paying Agent, each other
       paying agency of the Company and the Fiscal Agent for, and to
       hold them harmless against, any loss, liability or expense
       reasonably incurred without gross negligence or bad faith on
       their part, arising out of or in connection with actions taken or
       omitted by any of them in reliance on any certificate furnished
       pursuant to this Section.

                 (c)  Interest on any Registered Security that is
       payable, and is punctually paid or duly provided for, on any
       interest payment date shall be paid to the person in whose name
       that Security is registered at the close of business on the June
       15 or December 15 immediately preceding such interest payment
       date (each a "Record Date"), even if such Registered Security is
       cancelled, upon redemption, conversion or otherwise, after such
       Record Date.  In case a Bearer Security is surrendered for
       exchange for a Registered Security after the close of business on
       any Record Date and before the opening of business on the next
       succeeding interest payment date, the Fiscal Agent shall not be
       required to perform such transfer or exchange of such Security.

                 (d)  Interest on any Registered Security that is
       payable upon conversion in accordance with Section 7(a) hereof
       shall be paid to the person in whose name that Security is
       registered immediately prior to the conversion, provided that if
       a Registered Security is converted after the close of business on
       a Record Date and before the opening of business on the next
       succeeding interest payment date, accrued interest shall be paid
       on the next succeeding interest payment date to the person in
       whose name that Security is registered at the close of business
       on that Record Date.

                 (e)  Any interest on any Registered Security that is
       payable, but is not punctually paid or duly provided for, on any
       interest payment date shall forthwith cease to be payable to the
       registered holder thereof on the relevant regular record date by
       virtue of having been such holder, and such defaulted interest
       may be paid by the Company to the registered holder of such
       registered Security on a subsequent record date established by
       the Company in any lawful manner if, after notice given by the
       Company to the Fiscal Agent of the proposed payment pursuant to
       this clause, such manner of payment shall be deemed practicable
       by the Fiscal Agent.
PAGE


                 (f)  Subject to the foregoing provisions of this
       Section 5, each Security delivered under this Agreement upon
       registration of transfer of or in exchange for or in lieu of any
       other Security shall carry all the rights to interest accrued and
       unpaid, and to accrue, which were carried by such other Security.

                 (g)  In order to provide for the payment of the
       principal of, premium, if any, and interest on the Securities as
       the same shall become due and payable, the Company shall pay to
       the Paying Agent at its office in London, in such coin or
       currency of the United States of America as at the time of
       payment is legal tender for the payment of public and private
       debts therein, and in same day funds, the following amounts (and
       the Company shall give notice to the Fiscal Agent at least one
       full Business Day prior to the date payment is due to the Paying
       Agent as to the means of such payment), to be held and applied by
       the Paying Agent as hereinafter set forth:

                 (i)  The Company shall pay to the Paying Agent on the
       Business Day immediately prior to each interest payment date in
       same day funds an amount sufficient to pay the interest due (and
       Additional Amounts, if any) on all the Securities outstanding on
       such interest payment date and the Paying Agent shall apply the
       amounts paid to it to the payment of such interest (and
       Additional Amounts, if any) on such interest payment date.

                 (ii) Upon presentment for conversion of any Securities
       pursuant to Section 7(a) hereof (except as described in the
       proviso to Section 5(d)), the Paying Agent shall promptly notify
       the Company of the amount of any accrued interest due and owing
       thereon.  Within four business days of such notification, the
       Company shall pay to the Paying Agent an amount sufficient to pay
       the accrued interest due on such Securities (and Additional
       Amounts, if any, thereon), and the Paying Agent shall apply the
       amounts so paid to it to the payment of such accrued interest
       (and Additional Amounts, if any, thereon) in accordance with the
       terms of the Securities.

                 (iii)     If the Company shall elect, or shall be
       required, to redeem the Securities in accordance with Section 6
       hereof, the Company will pay to the Paying Agent on the Business
       Day immediately prior to the date fixed for redemption thereof in
       same day funds an amount sufficient (with any amount then held by
       the Paying Agent and available for the purpose) to pay the
       redemption price of the Securities called for redemption on the
       redemption date or entitled to be redeemed, together with accrued
       interest thereon (and Additional Amounts, if any, thereon) to the
       date fixed for redemption and not paid pursuant to clause (g)(i)
       of this Section 5, and the Paying Agent shall apply such amount
       to the payment of the redemption price and accrued interest
       thereon (and Additional Amounts, if any, thereon) in accordance
       with the terms of the Securities.
PAGE


                 (iv) On the Business Day immediately prior to the
       maturity date of the Securities, the Company shall pay to the
       Paying Agent in same day funds an amount which, together with any
       amounts then held by the Paying Agent, and available for payment
       thereof, shall be equal to the entire amount of principal and
       interest (and Additional Amounts, if any) to be due on such
       maturity date on all the Securities then outstanding, and the
       Paying Agent shall apply such amount to each payment of the
       principal of and interest on (and Additional Amounts, if any, on)
       the Securities in accordance with the terms of the Securities.

                 (h)  Notwithstanding anything in this Section to the
       contrary, if any payment of interest or premium or principal (or
       Additional Amounts, if any) is due on a day that is not a
       Business Day, payment shall be made on the next succeeding
       Business Day, with the same effect as if made on the day such
       payment was due, and no interest shall accrue for the period
       after such date.  A "Business Day" is defined, with respect to
       any act to be performed pursuant hereto or to the Securities, as
       any day which is not a Saturday, Sunday or a day on which banking
       institutions in the place where such act is to occur are
       authorized or obligated by applicable law, regulation or
       executive order to close.

            6.   Redemption.

                 (a)  If, under the circumstances described in Section 3
       of the Registered Securities and Bearer Securities, the Company
       shall elect or be required to redeem outstanding Securities, the
       following provisions shall be applicable:

                 (i)  The Company shall, at least 35 days in the case of
       a redemption in whole or 75 days in the case of a redemption in
       part (or such shorter period as shall be reasonably acceptable to
       the Fiscal Agent) before the date designated for such redemption,
       give written notice to the Agents of its election to redeem the
       Securities on the redemption date specified in such notice and
       state in such notice that the conditions precedent to such
       redemption have occurred and describe them, and in case of
       redemptions pursuant to Section 3(b) of the Registered Securities
       and the Bearer Securities, shall provide to the Fiscal Agent an
       opinion of counsel satisfactory to the Fiscal Agent stating that
       the legal conditions precedent to the right of the Company to
       effect such redemption have occurred, and shall request the
       Fiscal Agent to arrange for publication and mailing of the notice
       specified in clause (a) (ii) below.

                 (ii) In case the Company shall give notice to the
       Agents of its election to redeem the Securities, the Fiscal Agent
       shall cause to be published on behalf of and at the expense of
       the Company a notice of redemption in accordance with the
       provisions of Section 3 of the Registered Securities and Bearer
       Securities and shall mail by first-class mail a copy of the
       notice to each holder of a Registered Security at the address of
PAGE


       such holder as it shall appear in the Security Register.  The
       Fiscal Agent shall send a copy of such notice of redemption to
       the Company, the Paying Agent (if different from the Fiscal
       Agent) and each other paying agency of the Company.

                 (iii)     Such notice shall be published on behalf and
       at the expense of the Company in an Authorized Newspaper (as
       defined in Section 19 hereof) on a Business Day in New York City
       and in London and, if the Securities are listed on the Luxembourg
       Stock Exchange and so long as listed thereon, in an Authorized
       Newspaper in Luxembourg, or, if publication in either London or
       Luxembourg is not practical, in an Authorized Newspaper in any
       country in Western Europe, as set forth in Section 19 of this
       Agreement and Section 3 of the Registered Securities and Bearer
       Securities.  In the case of a redemption in whole, notice will be
       given once not more than 60 nor less than 30 days prior to the
       date fixed for redemption.  In the case of partial redemption,
       notice will be given twice, the first such notice to be given not
       more than 75 nor less than 60 days prior to the date fixed for
       redemption and the second such notice to be given not more than
       60 and not less than 30 days prior to the date fixed for
       redemption.  The Fiscal Agent shall notify the Company promptly
       of the portions of outstanding Securities to be called for
       redemption as determined pursuant to Section 3(a) of the
       Registered Securities and Bearer Securities.

                 (b)  Under the circumstances described in Section 3(d)
       of the Registered Securities and Bearer Securities concerning the
       redemption of outstanding Securities at the option of the holders
       thereof, the following provisions shall be applicable:

                 (i)  The Company shall give notice to the Fiscal Agent
       of the occurrence of a Redemption Event (as defined in Section
       3(d) of the Registered Securities and Bearer Securities)
       immediately upon the occurrence of such Redemption Event.  Such
       notice shall state:

                      (A)  The nature of the Redemption Event;

                      (B)  The Holder Redemption Date (as defined in
       Section 3(d) of the Registered Securities and Bearer Securities)
       in respect of such Redemption Event; and

                      (C)  The redemption price as set forth in Section
       3(d) of the Registered Securities and Bearer Securities.

                 (ii) The Fiscal Agent shall cause to be published on
       behalf of the Company a notice of entitlement to redeem in
       accordance with the provisions of Section 3 of the Registered
       Securities and Bearer Securities and shall mail by first-class
       mail a copy of such notice to each holder of a Registered
       Security at the address of such holder as it shall appear in the
       Security Register.  The Fiscal Agent shall send a copy of such
       notice of entitlement to redeem to the Company, the Paying Agent
PAGE


       (if different from the Fiscal Agent) and each other paying agency
       of the Company hereunder.  Such notice shall be published on
       behalf and at the expense of the Company in Authorized Newspapers
       on a Business Day in New York City and in London and, if the
       Securities are listed on the Luxembourg Stock Exchange and so
       long as listed thereon, in an Authorized Newspaper in Luxembourg,
       or, if either publication in London or Luxembourg is not
       practical, in an Authorized Newspaper in any country in Western
       Europe, as set forth in Section 19 of this Agreement.  Notice
       shall be given not later than 10 days after the later of the
       Exchange Date or the date of the occurrence of a Redemption
       Event.

                 (iii)     Upon the deposit of any of the Registered
       Securities or Bearer Securities with the agency designated by the
       Company as the place for payment of the Registered Securities and
       Bearer Securities together with a duly signed and completed
       redemption notice in the form set forth on the reverse of the
       Bearer Securities and Registered Securities, all in accordance
       with the provisions of Section 3 of the Registered Securities and
       Bearer Securities, the holder of such Registered Security and
       Bearer Security shall be entitled to receive a non-transferable
       receipt evidencing such deposit.

                 (iv) The Fiscal Agent shall notify the Company on each
       Business Day in the five Business Days prior to the Holder
       Redemption Date for outstanding Securities to be redeemed under
       this Section 6(b) of the amount required to redeem such
       Securities.

       of the Registered Securities and Bearer Securities concerning the
       redemption of outstanding Securities at the option of the holders
       thereof upon a Change in Control of the Company that is not

       expiration of the Approval Period (all as defined and set forth
       in Section 3(e) of the Registered Securities and Bearer
       Securities), the following provisions shall be applicable:

                      (i)  The Company shall give notice to the Fiscal
       Agent of the occurrence of a Change in Control immediately upon
       the expiration of the Approval Period if such Change in Control
       has not been approved by a majority of the Continuing Directors
       prior to the expiration of the Approval Period.  Such notice
       shall state:

                      (A)  The nature of the Change in Control;

                           (B)  The Repurchase Date (as that term is
       defined in Section 3(e) of the               Registered
       Securities and Bearer Securities) in respect of such Change in
       Control; and

       Security at the address of such holder as it shall appear in the
       Security Register.  The Fiscal Agent shall send a copy of such
       notice of entitlement to redeem to the Company, the Paying Agent
       (if different from the Fiscal Agent) and each other paying agency
       of the Company hereunder.  Such notice shall be published on
       behalf and at the expense of the Company in Authorized Newspapers
       on a Business Day in New York City and in London and, if the

       Securities, all in accordance with the provisions of Section 3 of
       the Registered Securities and Bearer Securities,  the holder of

            7.   Conversion of Securities.

                 (a)  Subject to and upon compliance with the provisions
       of this Section 7, at the option of the holder thereof, any
       outstanding Registered Security or Bearer Security or, in the
       case of any outstanding Registered Security or Bearer Security of
       a denomination other than $1,000, any portion of the principal
       amount thereof which is $1,000 or an integral multiple of $1,000,
       may be converted into shares of the Company's common stock, par
       value $1.00 per share ("Common Stock"), issuable upon conversion
       of the Securities, at the principal amount thereof, or of such
       portion thereof, into fully paid and nonassessable shares of
       Common Stock ("Conversion Shares") as set forth in the Registered
PAGE


       Securities and Bearer Securities.  Such Registered Securities or
       Bearer Securities may be converted on or after the date which is
       the latest of: (i) the Exchange Date, (ii) March 15, 1996 and
       (iii) the date of the effectiveness of the Registration Statement
       to be filed by the Company under the Securities Act relating to
       the Common Stock issuable upon conversion of the Restricted
       Securities (the _Registration Date_), and in any event prior to
       redemption or maturity.  The right to convert Securities called
       for redemption will terminate at the close of business on the
       fifteenth day next preceding the date fixed for redemption (or if
       such date is not a Business Day, then the next succeeding
       Business Day), and will be lost if not exercised prior to that
       time.  No payment or adjustment shall be made upon any conversion
       on account of any dividends on the Common Stock issued upon
       conversion.  Accrued interest from the immediately preceding
       interest payment date until the conversion date (and Additional
       Amounts, if any, thereon) will be paid to the holder, through the
       Paying Agent, in the same manner as payments of interest, within
       five Business Days after the conversion date, provided that if a
       Registered Security is converted after the close of business on a
       Record Date and before the opening of business on the next
       succeeding interest payment date, accrued interest shall be paid
       on the next succeeding interest payment date to the person in
       whose name that Security is registered at the close of business
       on that Record Date.  The price at which Conversion Shares shall
       be delivered upon conversion (herein called the "Conversion
       Price") shall be initially $56.70 per share of Common Stock.  The
       Conversion Price shall be adjusted in certain instances as
       provided in paragraphs (c)(i), (ii), (iii), (iv), (vi) and (vii)
       of Section 4 of the Registered Securities and Bearer Securities.

                 (b)  In order to exercise the conversion privilege, the
       holder of any Security to be converted shall surrender such
       Security, or, if less than the entire principal amount of a
       Registered Security or Bearer Security of a denomination other
       than $1,000 is to be converted, the portion thereof to be
       converted, together with all unmatured coupons and any matured
       coupons in default appertaining thereto, at the office of the
       Conversion Agent or any office or agency of the Company
       maintained for that purpose pursuant to Section 12(f) hereof,
       accompanied by a duly signed and completed Conversion Notice, in
       substantially the form set forth in the Registered Securities and
       Bearer Securities, to the Company, at such office or agency that
       the holder elects to convert such Security (or specified portion
       thereof).

                 (c)  Securities shall be deemed to have been converted
       immediately prior to the close of business on the day of
       surrender of such Securities for conversion in accordance with
       the foregoing provisions, and at such time the rights of the
       holders of such Securities as holders shall cease, and the person
       or persons entitled to receive the Common Stock issuable upon
       conversion shall be treated for all purposes as the record holder
       or holders of such Common Stock at such time.  As promptly as
PAGE


       practicable on or after the conversion date, the Company shall
       cause to be issued or delivered at such office or agency a
       certificate or certificates for the number of full shares of
       Common Stock issuable or deliverable upon conversion, together
       with payment, in lieu of any fraction of a share, as provided
       below.  The Paying Agent shall, within five business days after
       the conversion date, make a payment for the accrued interest
       thereon (and Additional Amounts, if any, thereon), except as
       otherwise provided in this Section 7.

                 (d)  In the case of any Registered Security or Bearer
       Security of a denomination other than $1,000 which is converted
       in part only, upon such conversion the Company shall execute and
       the Fiscal Agent shall authenticate and deliver to the holder
       thereof, at the expense of the Company, a new Security or
       Securities of any authorized kind or denomination as requested by
       such holder, in aggregate principal amount equal to the
       unconverted portion of the principal amount of such Security.

                 (e)  No fractional shares of Common Stock shall be
       issued or delivered upon conversion of Securities.  If more than
       one Security shall be surrendered for conversion at one time by
       the same holder, the number of full shares of Common Stock which
       shall be issuable or deliverable upon conversion thereof shall be
       computed on the basis of the aggregate principal amount of the
       Securities (or, in the case of Registered Securities or Bearer
       Securities of a denomination other than $1,000, specified
       portions thereof) so surrendered.  Instead of any fractional
       share of Common Stock which would otherwise be issuable or
       deliverable upon conversion of any Security or Securities (or, in
       the case of Registered Securities or Bearer Securities of a
       denomination other than $1,000, specified portions thereof), the
       Company shall pay a cash adjustment in respect of such fraction
       in an amount equal to the same fraction of the Closing Price (as
       defined in Section 4(c)(v) of the Registered Securities and
       Bearer Securities) for a share of Common Stock at the close of
       business on the day preceding the day of conversion.

                 (f)  Whenever the Conversion Price is adjusted as
       provided in the Registered Securities and Bearer Securities:

                      (i)  the Company shall compute the adjusted
       Conversion Price in accordance with the terms of the Registered
       Securities and Bearer Securities and shall prepare a certificate
       signed by the President, any Vice President or the Treasurer of
       the Company setting forth the adjusted Conversion Price and
       showing in reasonable detail the facts upon which such adjustment
       is based, and such certificate shall forthwith be filed with the
       Conversion Agent and at each office or agency maintained for the
       purpose of conversion of Securities pursuant to Section 12(f)
       hereof; and

                      (ii) a notice stating that the Conversion Price
       has been adjusted and setting forth the adjusted Conversion Price
PAGE


       shall forthwith be prepared, and, as soon as practicable after it
       is prepared, the Company shall promptly cause a notice setting
       forth the adjusted Conversion Price to be given to the holders of
       the Securities.  Such notice shall be published on behalf and at
       the expense of the Company in Authorized Newspapers on a Business
       Day in New York City and in London and, if the Securities are
       listed on the Luxembourg Stock Exchange and so long as listed
       thereon, in an Authorized Newspaper in Luxembourg, or, if
       publication in either London or Luxembourg is not practical, in
       an Authorized Newspaper in any country in Western Europe, as set
       forth in Section 19 of this Agreement and Section 4 of the
       Registered Securities and Bearer Securities.

                 (g)  In case:

                 (i)  the Company shall declare a dividend (or any other
       distribution) on its Common Stock payable otherwise than in cash
       out of its retained earnings (excluding dividends payable in
       stock for which adjustment is made pursuant to the terms of the
       Registered Securities and Bearer Securities); or

                 (ii) the Company shall authorize the granting to the
       holders of its Common Stock of rights or warrants to subscribe
       for or purchase any shares of capital stock of any class or of
       any other rights; or

                 (iii)     of any reclassification of the Common Stock
       of the Company (other than a subdivision or combination of its
       outstanding shares of Common Stock), or of any consolidation
       with, or merger of the Company into, any other corporation, or of
       any merger of another corporation into the Company (other than a
       merger which does not result in any reclassification, conversion,
       exchange or cancellation of outstanding shares of Common Stock of
       the Company), or of any sale or transfer of all or substantially
       all of the assets of the Company (which shall not include the
       sale or transfer of any portion of the assets of the Company to
       any corporation which, immediately following such transfer is at
       least 51% owned by the Company, provided that such sale or
       transfer does not result in the reclassification, conversion,
       exchange or cancellation of outstanding shares of Common Stock of
       the Company); or

                 (iv) of the involuntary dissolution, liquidation or
       winding up of the Company; or

                 (v)  the Company proposes to take any other action
       which would require an adjustment of the Conversion Price
       pursuant to the Registered Securities and Bearer Securities; 

            then the Company shall cause to be filed with the Conversion
       Agent and at each office or agency maintained for the purpose of
       conversion of Securities a notice setting forth the adjusted
       Conversion Price and shall cause notice to be given as provided
       in Section 19 except that notice need be given once at least 20
PAGE


       days (or 10 days in any case specified in clause (i) or (iii)
       above) prior to the applicable record date hereinafter specified,
       stating (x) the date on which a record is to be taken for the
       purpose of such dividend, distribution, rights or warrants or, if
       a record is not to be taken, the date as of which the holders of
       Common Stock of record to be entitled to such dividend,
       distribution, rights or warrants is to be determined, or (y) the
       date on which a reclassification, consolidation, merger, sale,
       transfer, dissolution, liquidation or winding up is expected to
       become effective, and the date as of which it is expected that
       holders of Common Stock of record shall be entitled to exchange
       their shares of Common Stock for the securities, cash or other
       property deliverable upon such reclassification, consolidation,
       merger, sale, transfer, dissolution, liquidation or winding up.
       The failure to give notice required by this Section or any defect
       therein shall not affect the legality or validity of any
       dividend, distribution, rights, warrants, reclassification,
       consolidation, merger, sale, transfer, dissolution, liquidation
       or winding up, or the vote on any such action.

                 (h)  The Company shall, at all times, have reserved and
       available, free from preemptive rights, out of its authorized but
       unissued shares of Common Stock, for the purpose of effecting the
       conversion of Securities, the full number of Conversion Shares
       then issuable upon the conversion of all Securities (based on the
       aggregate principal amount of Securities outstanding).

                 (i)  The Company shall file, as soon as practicable
       following the Closing Date, a shelf registration statement with
       the United States Securities and Exchange Commission covering the
       resale of shares of Common Stock issuable upon conversion of the
       Restricted Securities (_Registrable Securities_); provided that
       any holder of any Restricted Securities shall not sell any shares
       pursuant to such registration statement unless and until it
       provides to the Company such information as the Company may
       reasonably request for use in connection with the identification
       of such holder as a selling stockholder in such registration
       statement, or any prospectus included therein, and no such sale
       shall be made by such holder pursuant to such registration
       statement unless and until such information is included by the
       Company in such registration statement or prospectus.  The
       Company shall in good faith use its best efforts and at its cost
       to cause such registration statement to be declared effective as
       promptly as practicable thereafter and to include in such
       registration statement the information provided by a holder as a
       selling stockholder and shall notify the Fiscal Agent of the
       effectiveness thereof and agrees to use its best efforts to (i)
       cause all registrations with, and to obtain any approvals by, any
       governmental authority under any Federal or state law of the
       United States that may be required in connection with the
       conversion of the Securities into Common Stock and the resale
       thereof, (ii) maintain the effectiveness of such registrations
       until the earlier of (a) three years from the latest date of
       original issuance of the Securities hereunder, or (b) the date
PAGE


       that Rule 144(k) under the Securities Act (or successor
       provision) is available for the resale of the shares of Common
       Stock issuable upon conversion of the Restricted Securities (or
       other securities issuable upon conversion of the Securities) and
       (iii) to list the shares of Common Stock required to be issued or
       delivered upon conversion of Securities (or other securities
       issuable upon conversion of the Securities) prior to such issue
       or delivery on such national securities exchange or automated
       over-the-counter trading market where such Common Stock is listed
       or traded at the time of such delivery. The Company shall,
       without limitation as to time, indemnify and hold harmless, to
       the fullest extent permitted by law, each holder of Registrable
       Securities, the officers, directors and agents and employees of
       each of them, each person who controls such holder (within the
       meaning of Section 15 of the Securities Act or Section 20 of the
       Securities Exchange Act of 1934, as amended) and the officers,
       directors, agents and employees of any such controlling person,
       from and against all losses, claims, damages, liabilities, costs
       (including, without limitation, the costs of preparation and
       attorneys' fees) and expenses (collectively, _Losses_), as
       incurred, arising out of or based upon any untrue or alleged
       untrue statement of a material fact contained in any such
       registration statement, or related prospectus or in any amendment
       or supplement thereto, or arising out of or based upon any
       omission or alleged omission to state therein a material fact
       required to be stated therein or necessary to make the statements
       therein not misleading, except insofar as the same are based
       solely upon information, if any, furnished in writing to the
       Company by such holder expressly for use therein; provided, that
       the Company shall not be liable to any holder of Registrable
       Securities to the extent that any such Losses arise out of or are
       based upon an untrue statement or alleged untrue statement or
       omission or alleged omission made in any preliminary prospectus
       if either (A)(i) such holder failed to send or deliver a copy of
       the final prospectus with or prior to the delivery of written
       confirmation of the sale by such holder of a Registrable Security
       to the person asserting the claim from which such Losses arise
       and (ii) the prospectus would have completely corrected such
       untrue statement or alleged untrue statement or such omission or
       alleged omission; or (B)(i) such untrue statement or alleged
       untrue statement, omission or alleged omission is completely
       corrected in an amendment or supplement to the prospectus and
       (ii) having previously been furnished by or on behalf of the
       Company with copies of the prospectus as so amended or
       supplemented, such holder thereafter fails to deliver such
       prospectus as so amended or supplemented, prior to or
       concurrently with the sale of a Registrable Security to the
       person asserting the claim from which such Losses arise.
       Promptly after receipt by an indemnified party under this
       Paragraph (i) of notice of any claim or the commencement of any
       action, the indemnified party shall, if a claim in respect
       thereof is to be made against the Company under this Paragraph
       (i) notify the Company in writing of the claim or the
       commencement of that action; provided, however, that the failure
PAGE


       to notify the Company shall not relieve it from any liability
       which it may have to an indemnified party otherwise than under
       this Paragraph (i).  If any such claim or action shall be brought
       against an indemnified party, and it shall notify the Company
       thereof, the Company shall be entitled to participate therein
       and, to the extent that it wishes, to assume the defense thereof
       with counsel reasonably satisfactory to the indemnified party.
       After notice from the Company to the indemnified party of its
       election to assume the defense of such claim or action, the
       Company shall not be liable to the indemnified party under this
       Paragraph (i) for any legal or other expenses subsequently
       incurred by the indemnified party in connection with the defense
       thereof; provided, however, if the defendants in any such action
       include both an indemnified party and the Company and the
       indemnified party shall have reasonably concluded that there may
       be legal defenses available to it and for other indemnified
       parties that are different from or additional to those available
       to the Company, the indemnified party or parties under this
       Paragraph (i) shall have the right to employ not more than one
       counsel to represent them and, in that event, the reasonable fees
       and expenses of not more than one such separate counsel shall be
       paid by the Company.  The Company shall not be liable for any
       settlement effected without its written consent of any claim or
       action.

                 (j)  The Company covenants that all shares of Common
       Stock which may be issued or delivered upon conversion of
       Securities (or other securities issuable upon conversion of the
       Securities) will upon issuance be fully paid and nonassessable
       and, except as provided in Section 13 hereof, the Company will
       pay all stamp, excise or similar taxes or duties, liens and
       charges with respect to the issue thereof.

                 (k)  All converted Securities shall be held by the
       Company, and may, at any time, be delivered to the Fiscal Agent
       for cancellation, which shall hold or dispose of the same in
       accordance with its policy for disposal of cancelled securities
       or as otherwise directed by the Company.  Converted Securities
       shall not be transferred.  The Conversion Agent shall give the
       Company prompt notice of all Securities which have been
       converted, and if the Fiscal Agent is not also the Conversion
       Agent, the Company will promptly give, or cause to be given,
       written notice to the Fiscal Agent of the serial numbers of all
       Securities which have been converted.

                 (1)  In case of any consolidation with, or merger of
       the Company into, any other corporation, or in case of any merger
       of another corporation into the Company (other than a merger
       which does not result in any reclassification, conversion,
       exchange or cancellation of outstanding shares of Common Stock of
       the Company), or in case of any sale or transfer of all or
       substantially all of the assets of the Company, the corporation
       formed by such consolidation or resulting from such merger (which
       shall not include the sale or transfer of any portion of the
PAGE


       assets of the Company to any corporation which, immediately
       following such transfer is at least 51% owned by the Company,
       provided that such sale or transfer does not result in the
       reclassification, conversion, exchange or cancellation of
       outstanding shares of Common Stock of the Company), or which
       acquires such assets, as the case may be, shall execute and
       deliver to the Fiscal Agent an amendment to the Fiscal Agency
       Agreement providing that the holder of each Registered Security
       and Bearer Security shall have the right during the period such
       Security shall be convertible as specified in the Registered
       Securities and Bearer Securities to convert such Security only
       into the kind and amount of securities, cash and other property
       receivable upon such consolidation, merger, sale or transfer by a
       holder of the number of shares of Common Stock of the Company
       into which such Security might have been converted immediately
       prior to such consolidation, merger, sale or transfer, assuming,
       if such consolidation, merger, sale or transfer is prior to the
       period such Security shall be convertible as specified in the
       Registered Securities and Bearer Securities, that the Securities
       were convertible at such time at the initial Conversion Price as
       adjusted pursuant to the terms of the Registered Securities and
       Bearer Securities.  Such amendment shall provide for adjustments
       which, for events subsequent to the effective date of such
       amendment, shall be as nearly equivalent as may be practicable to
       the adjustments provided for in the Registered Securities and the
       Bearer Securities.  The above provisions of this Section shall
       similarly apply to successive consolidations, mergers, sales or
       transfers.

                 (m)  Subject to Section 11(j) hereof, neither the
       Fiscal Agent nor the Conversion Agent or conversion agency
       appointed by the Company shall at any time be under any duty or
       responsibility to any holder of Securities to determine whether
       any facts exist which may require any adjustment of the
       Conversion Price, or with respect to the nature or extent of any
       such adjustment when made, or with respect to the method
       employed, or herein or in the Registered Securities and Bearer
       Securities provided to be employed, in making the same.  Neither
       the Fiscal Agent nor the Conversion Agent or conversion agency
       appointed by the Company shall be accountable with respect to the
       validity or value (or the kind or amount) of any shares of Common
       Stock or of any securities or property which may at any time be
       issued or delivered upon the conversion of any Security; and
       neither the Fiscal Agent nor the Conversion Agent or conversion
       agency appointed by the Company makes any representation with
       respect thereto.  Neither the Fiscal Agent nor the Conversion
       Agent or conversion agency appointed by the Company shall be
       responsible for any acts or omissions of the Company including
       without limitation any failure of the Company to issue, transfer
       or deliver any certificates representing shares of Common Stock
       or other securities or property or to make any cash payment upon
       the delivery of any Security for the purpose of conversion or to
       comply with any of the covenants contained in this Section 7.
PAGE


                 (n)  Any Common Stock issued upon conversion of a
       Restricted Security ("Restricted Common Stock") at any time prior
       to the date which is three years (or the then applicable holding
       period under Rule 144(k) under the Securities Act (or successor
       provision)) after the date of original issuance of such
       Restricted Security and the last date on which the Company or any
       affiliate of the Company was the owner thereof (or any
       predecessor),  and when a registration statement in respect of
       such Common Stock is not effective under the Securities Act,
       shall be subject to the restrictions on transfer set forth in
       Section 3 hereof to the same extent as such Restricted Securities
       which were so converted.  All shares of Restricted Common Stock
       shall bear the legend and transfer requirements set forth in
       Section 3(f) hereof, with such modifications thereto as the
       Company shall deem appropriate.

            8.   Surrendered Securities.

                 All Securities, together with any coupons appertaining
       thereto, surrendered for payment, redemption, retirement,
       transfer or exchange and all coupons paid through the application
       of interest installments and all Securities purchased by the
       Company or any subsidiary shall be delivered to the Fiscal Agent.
       In any such case the Fiscal Agent shall cancel all Securities and
       coupons not previously cancelled and destroy all such Securities
       and coupons so delivered and shall furnish to the Company a
       certificate with respect to such destruction.  Such certificate
       shall state, in the case of destruction of the Regulation S
       Global Security, that all certificates of the Euroclear Operator
       or Cedel S.A. as to beneficial ownership required by Section 4
       hereof have been duly presented by the Euroclear Operator or
       Cedel S. A.

            9.   Mutilated, Destroyed, Stolen or Lost Securities.

                 The Fiscal Agent is hereby authorized, in accordance
       with the provisions of the Securities and this Section, from time
       to time to authenticate and deliver Securities in exchange for or
       in lieu of Securities that become mutilated, destroyed, stolen or
       lost, upon receipt of indemnity and such other documents or proof
       as may be required in form and substance satisfactory to the
       Fiscal Agent and the Company.  Every Security authenticated and
       delivered in exchange for or in lieu of any such Security shall
       be considered obligations of the Company and shall carry all
       rights to interest accrued and unpaid and to accrue which were
       carried by such Security, and notwithstanding anything to the
       contrary herein contained, any new Bearer Security shall have
       attached thereto such coupons that neither gain nor loss in
       interest shall result from such exchange or substitution.

            10.  Signatures.

                 Securities shall be executed on behalf of the Company
       by its President, its Secretary, any Vice President or its
PAGE


       Treasurer, any of whose signatures may be manual or in facsimile,
       and any coupons appertaining thereto shall be executed on behalf
       of the Company by the facsimile signature of its President, its
       Secretary, any Vice President or its Treasurer.  Any signature in
       facsimile may be imprinted or otherwise reproduced on the
       Securities.  The Company may adopt and use the signature or
       facsimile signature of any person who shall be a President,
       Secretary, Vice President or Treasurer at the time of the
       execution of the Securities, notwithstanding the fact that at the
       time the Securities shall be authenticated and delivered, or
       disposed of, such person shall have ceased to have held such
       office by virtue of which such person so executed such security.

            11.  Agreements Concerning Agents.

                 Each of the Agents accepts its obligations herein and
       in the Securities, upon the terms and conditions hereof and
       thereof, including the following, to all of which the Company
       agrees and to all of which the rights hereunder of the holders
       from time to time of the Securities and coupons shall be subject:

                 (a)  Each of the Agents shall be entitled to reasonable
       compensation for all services rendered by such Agent, as
       separately agreed by the Company and the Agent, and the Company
       agrees promptly to pay such compensation and to reimburse each of
       the Agents for the reasonable out-of-pocket expenses (including,
       but not limited to, counsel fees) incurred by such Agent in
       connection with the services rendered by it hereunder.  The
       Company also agrees to indemnify each of the Agents and each
       other paying agency and conversion agency of the Company for, and
       to hold it harmless against, any loss, liability or expense
       (including the costs and expenses of defending against any claim
       of liability) incurred without negligence or bad faith on the
       part of such Agent or other paying agency and conversion agency
       of the Company hereunder.  The obligations of the Company under
       this clause (a) shall survive payment of the Securities or the
       resignation or removal of any Agent or paying agency or
       conversion agency.

                 (b)  In acting under this Agreement and in connection
       with the Securities, each of the Agents and each other paying
       agency and conversion agency of the Company is acting solely as
       agent of the Company, and does not assume any obligation, or
       relationship of agency or trust, for or with any of the owners or
       holders of the Securities or coupons, except that all funds held
       by the Paying Agent or any other paying agency of the Company for
       payment of principal, premium, if any, or interest on (or
       Additional Amounts, if any, on) the Securities shall be held in
       trust but need not be segregated from other funds except as
       required by law and as set forth herein and in the Securities,
       and shall be applied as set forth herein and in the Securities;
       provided, however, that monies paid by the Company to the Paying
       Agent or any other paying agency of the Company for the payment
       of principal of or interest on (or Additional Amounts, if any,
PAGE


       on) Securities remaining unclaimed at the end of two years after
       such principal or interest (or Additional Amounts, if any) shall
       have become due and payable shall be repaid to the Company, as
       provided and in the manner set forth in the Securities, whereupon
       the aforesaid trust shall terminate and all liability of the
       Paying Agent or such other paying agency or the Company with
       respect thereto shall cease.

                 (c)  Each of the Agents and each other paying agency
       and conversion agency of the Company may consult with one or more
       counsel satisfactory to it (including counsel to the Company),
       and the written opinion of such counsel shall be full and
       complete authorization and protection in respect of any action
       taken, omitted or suffered by it hereunder in good faith and in
       accordance with the opinion of such counsel.

                 (d)  Each of the Agents and each other paying agency
       and conversion agency of the Company shall be protected and shall
       incur no liability for or in respect of any action taken, omitted
       or suffered by it in reliance upon any Security or coupon,
       notice, direction, consent, certificate, affidavit, statement or
       other paper or document believed in good faith by such Agent or
       such other paying agency and conversion agency of the Company to
       be genuine and to have been signed by the property parties.

                 (e)  Each of the Agents and each other paying agency
       and conversion agency of the Company, its officers, directors and
       employees may become the owner of, or acquire any interest in,
       any Securities or coupons, with the same rights that it or they
       would have if it were not an Agent or such other paying agency of
       the Company hereunder, and may engage or be interested in any
       financial or other transaction with the Company and its
       affiliates and may act on, or as depositary, trustee or agent
       for, any committee or body of holders of Securities or other
       obligations of the Company, as freely as if it were not an Agent
       or a paying agency or conversion agency of the Company hereunder.

                 (f)  Neither the Paying Agent nor any other paying
       agency of the Company shall be under any liability for interest
       on any monies at any time received by it pursuant to any of the
       provisions of this Agreement or of the Securities.

                 (g)  The recitals contained herein and in the
       Securities (except in the Fiscal Agent's certificates of
       authentication), shall be taken as the statements of the Company,
       and the Agents assume no responsibility for the correctness of
       the same.  None of the Agents makes any representation as to the
       validity or sufficiency of this Agreement or the Securities or
       the coupons, except for such Agent's due authorization to execute
       this Agreement.  Neither the Agents nor any other paying agency
       or conversion agency of the Company shall be accountable for the
       use or application by the Company of the proceeds of any
       Securities authenticated and delivered by the Fiscal Agent in
       conformity with the provisions of this Agreement.

                 (h)  The Agents and each other paying agency and
       conversion agency of the Company shall be obligated to perform
       such duties and only such duties as are herein and in the
       Securities specifically set forth and no implied duties or
       obligations shall be read into this Agreement or the Securities
       against the Agents or any other paying agency of the Company.
       The Agents shall not be under any obligation to take any action
       hereunder which may tend to involve them in any expense or
       liability, the payment of which, within a reasonable time, is
       not, in their reasonable opinion, assured to them.

                 (i)  Unless herein or in the Securities otherwise
       specifically provided, any order, certificate, notice, request,
       direction, or other communication, from the Company made by or
       given by it under any provision of this Agreement shall be
       sufficient if signed by the President, the Secretary, any Vice
       President or the Treasurer of the Company.

                 (j)  Anything in this Agreement to the contrary
       notwithstanding, none of the Agents shall incur any liability
       hereunder, except as a result of negligence or bad faith
       attributable to it or its officers or employees, and shall incur
       no liability for the negligence or bad faith of its agents
       appointed by it with due care; provided that the Agent shall
       notify the Company of the appointment of any such agents.

                 (k)  The Agents shall not be liable for any loss caused
       by events beyond the reasonable control of the Agents, including
       any malfunction, interruption of or error in the transmission of
       information caused by any machines or systems or interruption of
       communication facilities, abnormal operating conditions or acts
       of God.  The Agents shall have no liability whatsoever for any
       consequential, special, indirect or speculative losses or
       damages.

            12.  Offices, Resignation, Successors, Etc. of Agents,
       Paying, Conversion and Transfer Agencies.

                 (a)  The Company agrees that, until none of the
       Securities and coupons are outstanding or until monies for the
       payment of all principal, premium, if any, and interest on (and
       Additional Amounts, if any, on) all outstanding Securities shall
       have been made available at the office of the Paying Agent and
       shall have been returned to the Company as provided in the
       Securities, there shall at all times be a Fiscal Agent in the
       Borough of Manhattan, New York City, which shall be a bank or
       trust company organized and doing business under the laws of the
       United States of America or of any State of the United States of
       America, in good standing and authorized under such laws to
       exercise corporate trust powers, a Paying Agent, a Conversion
       Agent and a Transfer Agent having offices in a city in Western
       Europe and in New York City, which shall be a bank or trust
       company organized, in good standing and doing business under the
PAGE


       laws of the United States of America or of any State of the
       United States of America, and a paying agency, a conversion
       agency and a transfer agency in at least one city in Western
       Europe, which shall be Luxembourg if the Securities are listed on
       the Luxembourg Stock Exchange and so long as listed thereon.

                 (b)  Each of the Agents may at any time resign as such
       Agent by giving written notice to the Company of such intention
       on its part, specifying the date on which its desired resignation
       shall become effective; provided, however, that such date shall
       not be less than 90 days after receipt of such notice by the
       Company unless the Company agrees to accept less notice.  Each of
       the Agents hereunder may be removed at any time by the filing
       with it of any instrument in writing signed on behalf of the
       Company and specifying such removal and the date when it is
       intended to become effective.  Such resignation or removal shall
       take effect upon the date of the appointment by the Company, as
       hereinafter provided, of a successor Fiscal Agent, Conversion
       Agent or Paying Agent, as the case may be, and the acceptance of
       such appointment by such successor Agent.  Upon its resignation
       or removal, each of the Agents shall be entitled to the payment
       by the Company of its compensation for the services rendered
       hereunder and to the reimbursement of all reasonable
       out-of-pocket expenses incurred in connection with the services
       rendered hereunder by such Agent and shall promptly notify the
       Company of such action.

                 (c)  In case at any time any of the Agents shall
       resign, or shall be removed, or shall be incapable of acting, or
       shall file a voluntary petition as a debtor under Chapter 7 or 11
       of Title 11 of the United States Code or have an order for relief
       entered against it as a debtor under Chapter 7 or 11 of Title 11
       of the United States Code or make an assignment for the benefit
       of its creditors or consent to the appointment of a receiver of
       all or any substantial part of its property, or shall admit in
       writing its inability to pay or meet its debts as they mature, or
       if an order of any court shall be entered approving any petition
       filed by or against the Fiscal Agent under any legislation
       similar to the provisions of Title 11 of the United States Code
       or against any of the Agents under the provisions of any
       legislation similar to the provisions of Title 11 of the United
       States Code, or if a receiver of it or of all or any substantial
       part of its property shall be appointed, or if any public officer
       shall take charge or control of it or of its property or affairs,
       for the purpose of rehabilitation, conservation or liquidation, a
       successor Agent, qualified as aforesaid, shall be appointed by
       the Company by an instrument in writing.  Upon the appointment as
       aforesaid of a successor Agent and acceptance by it of such
       appointment, the Agent so superseded shall cease to be such Agent
       hereunder.  If no successor Agent shall have been so appointed by
       the Company and shall have accepted appointment as hereinafter
       provided, any holder of a Security, on behalf of itself and all
       others similarly situated, or any Agent may petition any court of
PAGE


       competent jurisdiction for the appointment of a successor Agent
       and shall promptly notify the Company of such action.

                 (d)  Any successor Fiscal Agent, Conversion Agent,
       Transfer Agent or Paying Agent appointed hereunder shall execute,
       acknowledge and deliver to its predecessor and to the Company an
       instrument accepting such appointment hereunder, and thereupon
       such successor Agent, without any further act, deed or
       conveyance, shall become vested with all the authority, rights,
       powers, trusts, immunities, duties and obligations of such
       predecessor with like effect as if originally named as such Agent
       hereunder, and such predecessor, upon payment of its charges and
       disbursements then unpaid, shall thereupon become obligated to
       transfer, deliver and pay over, and such successor Agent shall be
       entitled to receive, all monies, securities or other property on
       deposit with or held by such predecessor, as such Agent
       hereunder.

                 (e)  Any corporation or bank into which any of the
       Agents hereunder may be merged or converted, or any corporation
       or bank with which such Agent may be consolidated, or any
       corporation or bank resulting from any merger, conversion or
       consolidation to which such Agent shall be a party, or any
       corporation or bank to which such Agent shall sell or otherwise
       transfer all or substantially all the assets and business of such
       Agent, or any corporation to which the Fiscal Agent shall sell or
       otherwise transfer all or substantially all of its corporate
       trust business, provided that it shall be qualified as aforesaid,
       shall be the successor to such Agent under this Agreement without
       the execution or filing of any document or any further act on the
       part of any of the parties hereto.

                 (f)  So long as there shall be a Fiscal Agent and
       Paying Agent hereunder, the Company shall maintain agencies (i)
       where Registered Securities (but not Bearer Securities or
       coupons) may be presented for surrender for payment (and for the
       payment of Additional Amounts on the Registered Securities, if
       any) and where Securities may be surrendered for conversion in
       the Borough of Manhattan, New York City, and (ii) where Bearer
       Securities and coupons may be surrendered for payment (and for
       the payment of Additional Amounts (pursuant to Section 2 of the
       Bearer Securities) on Bearer Securities, if any) and where Bearer
       Securities may be surrendered for conversion in at least one city
       in Western Europe, which shall be Luxembourg if the Securities
       are listed on the Luxembourg Stock Exchange and so long as listed
       thereon.  The Company now intends to maintain additional agencies
       (subject to applicable laws and regulations) where Bearer
       Securities may be surrendered for payment (and for the payment of
       Additional Amounts (pursuant to Section 2 of the Bearer
       Securities) on Bearer Securities, if any), where Registered
       Securities may be surrendered for payment and where Securities
       may be surrendered for conversion in London, England and, if the
       Securities are listed on the Luxembourg Stock Exchange and so
       long as listed thereon, Luxembourg, and during such period to
PAGE


       keep the Agents advised of the names and locations of such
       agencies.  Unless the Company shall otherwise notify each of the
       Agents in writing, the sole such paying agencies and conversion
       agencies shall be the agencies specified in the Securities.  The
       Company authorizes the Paying Agent to pay to or to the order of
       the aforesaid agencies, upon demand by such agencies, funds for
       the payment of the principal, premium, if any, and interest on
       (and Additional Amounts pursuant to Section 2 of the Registered
       Securities and Bearer Securities, if any, on) the Securities.
       Except as otherwise arranged by the Company, the Fiscal Agent
       shall arrange for the payment of the compensation of such paying
       agencies for their services as such, and the Company shall pay to
       the Fiscal Agent from time to time sufficient funds to make such
       payments.

                 (g)  So long as there shall be a Fiscal Agent, Paying
       Agent and Conversion Agent hereunder, the Company shall maintain
       a Security Registrar and additional transfer agencies (the
       "Transfer Agents") (i) where Registered Securities may be
       surrendered for exchange for other Registered Securities in New
       York City and (ii) in at least one city in Western Europe, which
       shall be Luxembourg if the Securities are listed on the
       Luxembourg Stock Exchange and so long as listed thereon, where
       Bearer Securities may be delivered in exchange for Bearer
       Securities or for Registered Securities.  Consistent with
       applicable laws and regulations, including the provisions of the
       federal income tax laws of the United States, such agencies may
       be the same agencies as or different agencies from those
       maintained by the Company pursuant to Section 12(f).

                 The Company hereby appoints, subject to the listing of
       the Securities on the Luxembourg Stock Exchange, Banque
       Internationale a Luxembourg, 69, route d'Esch, L-1470 Luxembourg
       Ville, Luxembourg, as Transfer Agent for such exchanges.  The
       transfer, exchange and registration of transfer or exchange of
       Registered Securities shall be made by the Fiscal Agent in New
       York City.

            13.  Taxes.

                 The Company will pay all stamp taxes and other similar
       duties, if any, that may be imposed by the United States of
       America or the United Kingdom, or any state or political
       subdivision thereof or taxing authority therein, with respect to
       the execution or delivery of this Agreement, or the issuance of
       the Regulation S Global Security, or the exchange from time to
       time of the Regulation S Global Security for Registered
       Securities and Bearer Securities, or with respect to the issue or
       delivery of shares of Common Stock on conversion of Securities;
       provided, however, that the Company shall not be required to pay
       any tax or duty which may be payable in respect of any transfer
       involved in the issue or delivery of shares of Common Stock in a
       name other than that of the holder of the Security or Securities
       to be converted, and no such issue or delivery shall be made
PAGE


       unless and until the person requesting such issue has paid to the
       Company the amount of any such tax or duty or has established to
       the satisfaction of the Company that such tax or duty has been
       paid; and further provided that the Company shall not be required
       to pay any tax or duty that may be payable in respect of any
       accrued interest paid in connection with the conversion of the
       Securities.

            14.  Meetings and Votes of Holders.

                 (a)  A meeting of holders of Securities may be called
       at any time and from time to time pursuant to this Section for
       any of the following purposes: (i) to give any notice to the
       Company or to the Fiscal Agent, or to give any directions to the
       Fiscal Agent, or to consent to the waiving of any default
       hereunder or under the Registered Securities and Bearer
       Securities and its consequences, or to take any other action
       authorized to be taken by holders of Securities pursuant to
       Section 9 of the Registered Securities and Bearer Securities; or
       (ii) to take any other action authorized to be taken by or on
       behalf of the holders of any specified aggregate principal amount
       of the Securities under any other provision of this Agreement,
       the Registered Securities and Bearer Securities or under
       applicable law.

                 (b)  Meetings of holders of Securities may be held at
       such place or places in New York City or London as the Fiscal
       Agent or, in case of its failure to act, the Company or the
       holders calling the meeting shall from time to time determine.

                 (c)  The Fiscal Agent may at any time call a meeting of
       holders of Securities to be held at such time and at such place
       in any of the locations designated in Section 14(b) hereof as the
       Fiscal Agent shall determine.  Notice of every meeting of holders
       shall be made as specified in Section 19 hereof, except that such
       notice shall set forth the time and the place of such meeting, in
       general terms the action proposed to be taken at such meeting and
       a general description of regulations applicable to such meeting,
       and shall be published at least three times in the publications
       specified in such Section 19, the first publication to be not
       less than 21 nor more than 180 days prior to the date fixed for
       the meeting.

                 (d)  In case at any time the Company or the holders of
       at least 25% in aggregate principal amount of the Securities
       shall have requested the Fiscal Agent to call a meeting of the
       holders, by written request setting forth in reasonable detail
       the action proposed to be taken at the meeting, and the Fiscal
       Agent shall not have given the first notice of such meeting
       within 21 days after receipt of such request or shall not
       thereafter proceed to cause the meeting to be held as provided
       herein, then the Company or the holders of Securities in the
       amount above specified may determine the time and the place in
       either of the locations designated in Section 14(b) hereof for
PAGE


       such meeting and may call such meeting to take any action
       authorized in Section 14(a) hereof by giving notice thereof as
       provided in Section 14(c) hereof.

                 (e)  To be entitled to vote at any meeting of holders
       of Securities, a person shall be (i) a holder of one or more
       Securities, or (ii) a person appointed by an instrument in
       writing as proxy for a holder or holders of Securities by such
       holder or holders, which proxy need not be a holder of
       Securities.  The only persons who shall be entitled to be present
       or to speak at any meeting of holders shall be the persons
       entitled to vote at such meeting and their counsel and any
       representatives of the Fiscal Agent and its counsel and any
       representatives of the Company and its counsel.

                 (f)  The persons entitled to vote a majority in
       principal amount of the outstanding Securities shall constitute a
       quorum for the transaction of all business specified in Section
       14(a) hereof. No business shall be transacted in the absence of a
       quorum unless a quorum is represented when the meeting is called
       to order.  In the absence of a quorum within 30 minutes of the
       time appointed for any such meeting, the meeting shall, if
       convened at the request of the holders of Securities (as provided
       in Section 14(d) hereof), be dissolved.  In any other case the
       meeting shall be adjourned for a period of not less than 10 days
       as determined by the chairman of the meeting prior to the
       adjournment of such adjourned meeting.  Notice of the reconvening
       of any adjourned meeting shall be given as provided in Section
       14(c) hereof except that such notice need be published only once
       but must be given not less than five days prior to the date on
       which the meeting is scheduled to be reconvened.  Subject to the
       foregoing, at the reconvening of any meeting adjourned for a lack
       of a quorum the persons entitled to vote 25% in principal amount
       of the Securities outstanding shall constitute a quorum for the
       taking of any action set forth in the notice of the original
       meeting.  Notice of the reconvening of an adjourned meeting shall
       state expressly the percentage of the aggregate principal amount
       of the Securities that shall constitute a quorum.  At a meeting
       or an adjourned meeting duly reconvened and at which a quorum is
       present as aforesaid, any resolution and all matters (except as
       limited by Section 9 of the Registered Securities and Bearer
       Securities) shall be effectively passed and decided if passed or
       decided by the persons entitled to vote a majority in principal
       amount of the Securities represented and voting at such meeting,
       provided that such amount shall be not less than 25% in principal
       amount of the Securities outstanding.  Any holder of a Security
       who has executed an instrument in writing appointing a person as
       his proxy shall be deemed to be present for the purposes of
       determining a quorum and be deemed to have voted; provided,
       however, that such holder shall be considered as present or
       voting only with respect to the matters covered by such
       instrument in writing.  Any resolution passed or decision taken
       at any meeting of the holders of Securities duly held in
       accordance with this Section 14 shall be binding on all the
PAGE


       holders of Securities whether or not present or represented at
       the meeting.

                 (g)  Notwithstanding any other provision of this
       Agreement, the Fiscal Agent may make such reasonable regulations
       as it may deem advisable for any meeting of holders of Securities
       in regard to proof of the holding of Securities and of the
       appointment of proxies and in regard to the appointment and
       duties of inspectors of votes, the submission and examination of
       proxies, certificates and other evidence of the right to vote,
       and such other matters concerning the conduct of the meeting as
       it shall deem appropriate.  Except as otherwise permitted or
       required by any such regulations, the holding of Bearer
       Securities shall be proved by the production of the Bearer
       Securities or by a certificate executed, as depositary, by, and
       the appointment of any proxy shall be proved by having the
       signature of the person executing the proxy witnessed or
       guaranteed by, in each case, any trust company, bank or banker
       satisfactory to the Fiscal Agent.  Such regulations may provide
       that written instruments appointing proxies, regular on their
       face, may be presumed valid and genuine without the proof
       specified herein or other proof.  The holding of Registered
       Securities shall be proved by the registry books maintained in
       accordance with Section 2(d) hereof or by a certificate or
       certificates of the Fiscal Agent in its capacity as Company's
       agent for the maintenance of such books.

                 (h)  The Fiscal Agent shall, by an instrument in
       writing, appoint a temporary chairperson and a temporary
       secretary of the meeting, unless the meeting shall have been
       called by the Company or by the holders of Securities or the
       Fiscal Agent at the request of the Company or the holders of
       Securities as provided in Section 14(d) hereof and in the
       Securities, in which case the Company or the holders calling the
       meeting, as the case may be, shall in like manner appoint a
       temporary chairperson and a temporary secretary.  A permanent
       chairperson and a permanent secretary of the meeting shall be
       elected by vote of the holders of a majority in principal amount
       of the Securities represented at the meeting and entitled to
       vote.

                 (i)  At any meeting each holder or proxy shall be
       entitled to one vote for each U.S.$1,000 principal amount of
       Securities held or represented by him; provided, however, that no
       vote shall be cast or counted at any meeting in respect of any
       Securities challenged as not outstanding and ruled by the
       chairperson of the meeting to be not outstanding.  The
       chairperson of the meeting shall have no right to vote, except as
       a holder or proxy.

                 (j)  Any meeting of holders of Securities duly called
       pursuant to Section 14(c) or 14(d) hereof at which a quorum is
       present may be adjourned from time to time by vote of the holders
       (or proxies for the holders) of a majority in principal amount of
PAGE

       the Securities represented at the meeting and entitled to vote;
       and the meeting may be held as so adjourned without further
       notice.

                 (k)  The vote upon any resolution submitted to any
       meeting of holders of Securities shall be by written ballots on
       which shall be subscribed the signatures of the holders of
       Securities or of their representatives by proxy and the serial
       number or numbers of the Securities held or represented by them.
       The permanent chairperson of the meeting shall appoint two
       inspectors of votes who shall count all votes cast at the meeting
       for or against any resolution and who shall make and file with
       the secretary of the meeting their verified written reports in
       triplicate of all votes cast at the meeting.  A record, at least
       in triplicate, of the proceedings of each meeting of holders of
       Securities shall be prepared by the secretary of the meeting and
       there shall be attached to said record the original reports of
       the inspectors of votes on any vote by ballot taken thereat and
       affidavits by one or more persons having knowledge of the facts
       setting forth a copy of the notice of the meeting and showing
       that said notice was published as provided in Section 14(c) or
       14(d) hereof and, if applicable, Section 14(f) hereof.  Each copy
       shall be signed and verified by the affidavits of the permanent
       chairperson and secretary of the meeting, and one such copy shall
       be delivered to the Company and another to the Fiscal Agent to be
       preserved by the Fiscal Agent, the copy delivered to the Fiscal
       Agent to have attached thereto the ballots voted at the meeting.
       Any record so signed and verified shall be conclusive evidence of
       the matters therein stated.

            15.  Merger, Consolidation or Sale of Assets.

                 (a)  If at any time there shall be a merger,
       consolidation, sale or conveyance of assets or assumption of
       obligations to which any of the covenants contained in Section 6
       of the Registered Securities and Bearer Securities is applicable,
       then in any such event the successor or assuming corporation
       referred to therein will promptly deliver to the Fiscal Agent:

                 (i)  a certificate signed by an executive officer of
       such successor or assuming corporation stating that as of the
       time immediately after the effective date of any such
       transaction, the covenants of the Company contained in the
       Registered Securities and Bearer Securities have been complied
       with and the successor or assuming corporation is not in default
       under the provisions of this Agreement or the Securities, as
       applicable; and

                 (ii) a written opinion of legal counsel (who may be an
       employee of or counsel to the successor or assuming corporation)
       stating that, in such counsel's opinion, such covenants have been
       complied with and that any instrument or instruments executed in
       the performance of such covenants comply with the requirements
       thereof.

                 In case of any such merger, consolidation, sale,
       conveyance or assumption, such successor or assuming corporation
       shall succeed to and be substituted for the Company with the same
       effect, subject to (in the case of a merger to which the Company
       is a party) Section 6(b) of the Registered Securities and Bearer
       Securities, as if such successor or assuming corporation had been
       named herein and in the Registered Securities and Bearer
       Securities as the Company; the Company shall thereupon be
       relieved of any further obligation or liability hereunder or upon
       the Securities, provided that any successor or assuming
       corporation shall have the right to redeem the Securities,
       pursuant to Section 3(b) of the Registered Securities and Bearer
       Securities, only as a result of circumstances which occur
       subsequent to such merger, consolidation, sale, conveyance or
       assumption and as a result of which the Company would have had
       such right if the Company had remained the obligor on the
       Securities.  The Company, as the predecessor corporation may
       thereupon or at any time thereafter be dissolved, wound up or
       liquidated.  If applicable, such successor or assuming
       corporation thereupon may cause to be signed, and may issue
       either in its own name or in the name of the Company any or all
       of the Securities issuable hereunder which theretofore shall not
       have been executed on behalf of the Company and delivered to the
       Fiscal Agent; and, upon the order of such successor or assuming
       corporation, instead of the Company, and subject to all the
       terms, conditions and limitations in this Agreement prescribed,
       the Fiscal Agent shall authenticate and shall deliver any
       Securities which previously shall have been signed and delivered
       by the officers of the Company to the Fiscal Agent for
       authentication, and any Securities which such successor or
       assuming corporation thereafter shall cause to be signed and
       delivered to the Fiscal Agent for that purpose.  All the
       Securities so issued shall in all respects have the same legal
       rank and benefit under this Agreement as the Securities
       theretofore or thereafter issued in accordance with the terms of
       this Agreement as though all of such Securities had been issued
       at the date of the execution hereof.

                 In case of any merger, consolidation, sale, conveyance
       or assumption, such changes in phraseology and form (but not in
       substance) may be made in the Securities thereafter to be issued
       as may be appropriate.

                 (b)  The Fiscal Agent may rely on the documents
       delivered pursuant to this Agreement by any successor or assuming
       corporation pursuant to this Section 15 as conclusive evidence
       that any such merger, consolidation, sale, conveyance or
       assumption complies with the provisions of this Section and the
       Securities.

            16.  Governing Law.
PAGE


                 THIS AGREEMENT, THE SECURITIES AND ANY COUPONS
       APPERTAINING THERETO SHALL BE GOVERNED BY AND CONSTRUED IN
       ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS,
       UNITED STATES OF AMERICA, WITHOUT GIVING EFFECT TO ITS CONFLICTS
       OF LAW RULES.

            17.  Amendments.

                 This Agreement may be amended by the parties hereto,
       and certain provisions hereof may be waived, in the manner
       provided in Section 9 of the Registered Securities and Bearer
       Securities.  This Agreement may also be amended by the parties
       hereto, without the consent of the holder of any Security, for
       the purposes set forth in Section 9 of the Registered Securities
       and Bearer Securities and for the purpose of curing any
       ambiguity, or of curing, correcting or supplementing any
       defective provision contained herein or in any manner that the
       parties may mutually deem necessary or desirable, and that shall
       not materially adversely affect the interests of the holders of
       the Securities.

            18.  Agent for Service of Process.

                 As long as any of the Securities or coupons
       appertaining thereto remain outstanding, the Company will at all
       times have an authorized agent in the City of New York, upon whom
       process may be served in any legal action or proceeding arising
       out of or relating to this Agreement or any Security or any
       coupons appertaining thereto.  Service of process upon such agent
       and written notice of such service mailed or delivered to the
       Company shall to the extent permitted by law be deemed in every
       respect effective service of process upon the Company in any such
       legal action or proceeding.  The Company hereby appoints the
       Fiscal Agent as its agent for such purpose, and covenants and
       agrees that service of process in any legal action or proceeding
       may be made upon it at the office of such agent located at 450
       West 33rd Street, 15th Floor, New York, New York 10001  (or such
       other address in the City of New York, as may be the principal
       corporate trust office of such agent), unless and until the
       Company shall designate another agent for such purpose by written
       notice to the Fiscal Agent.  If the Fiscal Agent receives any
       such service of process, it shall promptly notify the Company of
       such service.

            19.  Notices.

            All notices hereunder shall be deemed to have been given

       (FORM OF FACE OF REGISTERED SECURITY)

                 Unless and until it is exchanged in whole or in part
       for Securities in definitive form, this Security may not be
       transferred except as a whole by the Depository to a nominee of
       the Depository or by a nominee of the Depository to the
       Depository or another nominee of the Depository or by the
       Depository or any such nominee to a successor depository or a
       nominee of such successor Depository.  Unless this certificate is
       presented by an authorized representative of The Depository Trust
       Company, a New York corporation (55 Water Street, New York, New
       York) ("DTC"), to the issuer or its agent for registration of
       transfer, exchange or payment, and any certificate issued is
       registered in the name of Cede & Co. or such other name as may be
       requested by an authorized representative of DTC (and any payment
       is made to Cede & Co. or such other entity as may be requested by
       an authorized representative of DTC), ANY TRANSFER, PLEDGE OR
       OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
       WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has
       an interest herein.

       THE BENEFIT OF THE COMPANY THAT: (I) IT HAS ACQUIRED A
       "RESTRICTED" SECURITY WHICH HAS NOT BEEN REGISTERED UNDER THE

       ORIGINAL ISSUANCE HEREOF AND THE LAST DATE ON WHICH THE COMPANY
       OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF SUCH RESTRICTED

                 Thermo Electron Corporation, a corporation duly
       incorporated and existing under the laws of the State of Delaware
       (the "Company"), for value received, hereby promises to pay to
       ________________, or registered assigns, the principal sum of
       __________________ United States Dollars on January 1, 2003 upon
       presentation and surrender hereof and to pay interest thereon,
       from January 3, 1996 or from the most recent Interest Payment
       Date (as defined below) to which interest has been paid or duly
       provided for, semiannually in arrears on January 1 and July 1 in
       each year (each an "Interest Payment Date"), commencing July 1,
       1996, at the rate of 4q% per annum, until the principal hereof is
       paid or made available for payment.  Interest hereon shall be
       calculated on the basis of a 360-day year comprised of twelve
       30-day months.  The interest so payable, and punctually paid or
       duly provided for, on any Interest Payment Date will, as provided
       in the Fiscal Agency Agreement (as defined on the reverse
       hereof), be paid to the person in whose name this Security is
       registered at the close of business on the Record Date for such
       interest payment, which shall be the December 15 or June 15
       (whether or not a Business Day (as defined on the reverse
       hereof)) next preceding such Interest Payment Date.  Except as
       otherwise provided in the Fiscal Agency Agreement (as defined on
       the reverse hereof), any such interest not so punctually paid or
       duly provided for will forthwith cease to be payable to the
       holder on such Record Date and may be paid at any time in any
       lawful manner, all as more fully provided in the Fiscal Agency
       Agreement.  Payment of interest on this Security shall be made by
       United States dollar check drawn on a bank in the City of New
       York and mailed to the person entitled thereto at his address as
       it shall appear in the Security Register, or (if arrangements
       satisfactory to the Company and the Fiscal Agent are made) by
       wire transfer to a United States dollar account maintained by the
       payee with a bank in the City of New York; provided, however,
       that if such mailing is not possible and no such application
       shall have been made, payment of interest shall be made at the
       principal corporate trust office of the Fiscal Agent, or such
       other office or agency of the Company as may be designated for
       such purpose in the City of New York, in United States currency.

                 Reference is hereby made to the further provisions of
       this Security set forth under Terms and Conditions of the
       Securities on the reverse hereof, which further provisions shall
       for all purposes have the same effect as if set forth at this
       place.

       signatory of the Fiscal Agent.

                 IN WITNESS WHEREOF, the Company has caused this

       outside the United States, its territories and its possessions.

       coupons may be made at the office of the Fiscal Agent in the City

       place.

                 Neither this Security nor any of the coupons attached
       hereto shall become valid or enforceable for any purpose unless
       and until the certificate of authentication hereon shall have

             (FORM OF REVERSE OF REGISTERED AND BEARER SECURITIES)

                     Terms and Conditions of the Securities
       1.   General.

            (a)  This Security is one of a duly authorized issue of
       Securities of the Company designated as its 4q% Convertible
       Subordinated Debentures Due 2003 (herein called the
       "Securities").  The Company, for the benefit of the holders from
       time to time of the Securities, has entered into a Fiscal Agency
       Agreement dated as of January 3, 1996 (the "Fiscal Agency
       Agreement") between the Company and Chemical Bank, as Fiscal
       Agent, Paying Agent, Security Registrar and Conversion Agent (the
       "Fiscal Agent"), to which Fiscal Agency Agreement reference is
       hereby made for a statement of the respective rights, limitations
       of rights, duties and immunities thereunder of the Company, the
       Fiscal Agent, and the holders of Securities and any coupons
       appertaining thereto and of the terms upon which the Securities
       are, and are to be, authenticated and delivered.  The holders of
       the Securities will be entitled to the benefits of, be bound by,
       and be deemed to have notice of, all of the provisions of the
       Fiscal Agency Agreement.  A copy of the Fiscal Agency Agreement
       is on file and may be inspected at the office of paying agencies
       appointed by the Company.

            (b)  The Securities are issuable as bearer securities (the
       "Bearer Securities"), with interest coupons attached, in the
       denominations of U.S. $1,000 and U.S. $10,000, and as registered
       securities (the "Registered Securities"), without coupons, in
       denominations of U.S. $1,000 and integral multiples thereof.  The
       Registered Securities, and transfers thereof, shall be registered
       as provided in Section 8 hereof and in the Fiscal Agency
       Agreement.  The holder of any Bearer Security or any coupon and
       the registered holder of a Registered Security shall (to the
       fullest extent permitted by applicable law) be treated at all
       times, by all persons and for all purposes as the absolute owner
       of such Security or coupon, as the case may be, regardless of any
       notice of ownership, theft or loss or of any writing thereon.

            (c)  The Securities are direct and unsecured obligations of
       the Company, subordinated as set forth in Section 7 hereof.
       There are no restrictions herein on other indebtedness or
       securities which may be incurred or issued by the Company.

            2.   Additional Amounts.  The Company will pay to the holder
       of this Security or of any coupon appertaining hereto who is a
       United States Alien (as defined below) such additional amounts
       (_Additional Amounts") as may be necessary in order that every
       net payment of the principal of, premium, if any, and interest on
       this Security,  after withholding for or on account of any
       present or future tax, assessment or governmental charge imposed
       upon or as a result of such payment by the United States or any
PAGE


       political subdivision or taxing authority thereof or therein,
       will not be less than the amount provided herein or in any coupon
       appertaining hereto to be then due and payable; provided,
       however, that the foregoing obligation to pay Additional Amounts
       shall not apply to any one or more of the following:

                 (a)  any tax, assessment or other governmental charge
       which would not have been so imposed but for (i) the existence of
       any present or former connection between such holder (or between
       a fiduciary, settlor, beneficiary, member or stockholder of, or a
       person holding a power over, such holder, if such holder is an
       estate, trust, partnership or corporation) and the United States,
       including, without limitation, such holder (or such fiduciary,
       settlor, beneficiary, member, stockholder or person holding a
       power) being or having been a citizen or resident or treated as a
       resident thereof or being or having been engaged in a trade or
       business therein or being or having been present therein or
       having or having had a permanent establishment therein, or (ii)
       such holder's present or former status as a personal holding
       company, foreign personal holding company, passive foreign
       investment company, foreign private foundation or other foreign
       tax-exempt entity or controlled foreign corporation for United
       States tax purposes or a corporation which accumulates earnings
       to avoid United States Federal income tax, or (iii) such holder's
       status as a bank extending credit pursuant to a loan agreement
       entered into in the ordinary course of business;

                 (b)  any tax, assessment or other governmental charge
       which would not have been so imposed but for the presentation by
       the holder of this Security or any coupon appertaining hereto for
       payment on a date more than 10 days after the date on which such
       payment became due and payable or on the date on which payment
       thereof is duly provided, whichever occurs later;

                 (c)  any estate, inheritance, gift, sales, transfer or
       personal property tax or any similar tax, assessment or other
       governmental charge;

                 (d)  any tax, assessment or other governmental charge
       which would not have been imposed but for the failure to comply
       with certification, information, documentation or other reporting
       requirements concerning the nationality, residence, identity or
       present or former connection with the United States of the holder
       or beneficial owner of such Security or any related coupon if
       such compliance is required by statute, regulation or ruling of
       the United States or any political subdivision or taxing
       authority thereof as a precondition to relief or exemption from
       such tax, assessment or other governmental charge;

                 (e)  any tax, assessment or other governmental charge
       which is payable otherwise than by deduction or withholding from
       payments of principal of and premium, if any, or interest on this
       Security;
PAGE


                 (f)  any tax, assessment or other governmental charge
       imposed on interest received by a person holding, actually or
       constructively, 10% or more of the total combined voting power of
       all classes of stock of the Company entitled to vote; or

                 (g)  any tax, assessment or other governmental charge
       required to be withheld by any paying agent from any payment of
       principal, or premium, if any, or interest on any Security or
       interest on any coupon appertaining thereto if such payment can
       be made without such withholding by any other paying agent; nor
       will Additional Amounts be paid with respect to any payment of
       the principal of, premium, if any, or interest on this Security
       (or cash in lieu of issuance of shares of Common Stock upon
       conversion) to a person other than the sole beneficial owner of
       such payment, or that is a partnership or fiduciary to the extent
       such beneficial owner, member of such partnership or beneficiary
       or settlor with respect to such fiduciary would not have been
       entitled to the payment of Additional Amounts had such beneficial
       owner, member, beneficiary or settlor been the holder of this
       Security or any coupon appertaining hereto.

                 The term "United States Alien" means any person who,
       for United States Federal income tax purposes, is a foreign
       corporation, a non-resident alien individual, a foreign
       partnership, or an estate or trust subject to United States
       Federal income tax on net income basis, and the term "United
       States" means the United States of America (including the several
       States and the District of Columbia), its territories, its
       possessions and other areas subject to its jurisdiction.

                 Except as specifically provided herein and in the
       Fiscal Agency Agreement, the Company shall not be required to
       make any payment with respect to any tax, assessment or other
       governmental charge imposed by any government or any political
       subdivision or taxing authority thereof or therein.

                 Whenever any Additional Amounts are to be paid on the
       Securities, the Company will give notice to the Fiscal Agent, the
       Paying Agent and any paying agency of the Company, all as
       provided in the Fiscal Agency Agreement.

            3.   Redemption.

                 (a)  The Company, at its option, may redeem the
       Securities, in whole or in part, at any time on or after January
       1, 1999, upon notice as hereinafter prescribed, at a redemption
       price equal to 100% of the principal amount thereof, together
       with accrued interest to the redemption date; provided, however,
       that in the event that the Company shall have elected to redeem
       all or any part of the Securities pursuant to this clause after
       the date on which a Change in Control (as defined in Section 3(e)
       hereof) shall have been determined to occur by the Continuing
       Directors (as defined in Section 3(e) hereof), which Change in
       Control shall not have been approved by the Continuing Directors,
PAGE


       the date on which such redemption may occur shall be not sooner
       than the first business day immediately following the Repurchase
       Date (as defined in Section 3(e) hereof).  In the event of a
       partial redemption, the Securities to be redeemed will be
       selected by the Fiscal Agent not more than 75 days before the
       date fixed for redemption by such method as the Fiscal Agent
       shall deem fair and appropriate. Provisions of this Security that
       apply to Securities called for redemption also apply to portions
       of Securities called for redemption.  The Fiscal Agent shall
       notify the Company promptly of the Securities or portions of
       Securities to be called for redemption.

                 (b)  If, at any time, the Company shall determine that
       as a result of any change in or amendment to the laws or any
       regulations or rulings of the United States or any political
       subdivision or taxing authority thereof or therein affecting
       taxation, or any amendment to, or change in, an official
       application or interpretation of such laws, regulations or
       rulings, which amendment or change is announced or becomes
       effective on or after November 28, 1995, the Company has or will
       become obligated to pay to the holder of any Security (other than
       the Restricted Securities) or coupon Additional Amounts and such
       obligation cannot be avoided by the Company taking reasonable
       measures available to it, then the Company may, at its election
       exercised at any time when such conditions continue to exist,
       redeem such Securities as a whole but not in part, upon notice as
       hereinafter prescribed, at a redemption price equal to 100% of
       the principal amount, together with accrued interest, if any, to
       the date fixed for redemption; provided that no such notice of
       redemption shall be given earlier than 90 days prior to the
       earliest date on which the Company would be obligated to pay such
       Additional Amounts were a payment in respect of such Securities
       then due; and provided  further that, at the time such notice is
       given, such obligations to pay such Additional Amounts remains in
       effect.

                 Prior to any redemption of the Securities pursuant to
       the preceding paragraph, the Company shall provide the Fiscal
       Agent with one or more certificates (signed by the President or
       any Vice President and the Treasurer or the Secretary) of the
       Company on which the Fiscal Agent may conclusively rely to the
       effect that the Company is entitled to redeem such Securities
       pursuant to such paragraph and that the conditions precedent to
       the right of the Company to redeem such Securities pursuant to
       such paragraph have occurred and a written opinion of counsel
       (who may be an employee of the Company) stating that all legal
       conditions precedent to the right of the Company to redeem such
       Securities pursuant to such paragraph have occurred.

                 (c)  Except as set forth in the next succeeding
       paragraph, the Company shall redeem the Bearer Securities as a
       whole but not in part, upon notice as hereinafter prescribed, at
       100% of their principal amount, together with interest accrued to
       the date fixed for redemption, less applicable withholding taxes,
PAGE


       if any, plus any applicable Additional Amounts payable, in the
       event that the Company determines that payment of principal of,
       premium, if any, or interest on a Bearer Security or a coupon
       appertaining thereto made outside the United States by the
       Company or a paying agent, based on a written opinion of counsel,
       would under any present or future laws or regulations of the
       United States be subject to any certification, identification or
       information reporting requirement with regard to the nationality,
       residence or identity of a beneficial owner of a Bearer Security
       or a coupon appertaining thereto who is a United States Alien
       (other than a requirement (a) that would not be applicable to a
       payment made by the Company or any one of its paying agents (i)
       directly to the beneficial owner or (ii) to a custodian, nominee
       or other agent of the beneficial owner, or (b) that can be
       satisfied by the custodian, nominee or other agent certifying
       that the beneficial owner is a United States Alien, provided,
       however, in each case referred to in clauses (a)(ii) and (b),
       payment by such custodian, nominee or other agent of the
       beneficial owner is not otherwise subject to any such
       requirement).  The Company shall make such determination on the
       basis of a written opinion of counsel and will notify the Fiscal
       Agent thereof in writing as soon as practicable, stating in the
       notice the effective date of such certification, identification,
       or information reporting requirement and the dates within which
       the redemption shall occur, and the Fiscal Agent shall give
       prompt notice thereof to the holders of the Securities in
       accordance with the Fiscal Agency Agreement.  The Company shall
       determine the redemption date by notice to the Fiscal Agent at
       least 75 days before the redemption date, unless shorter notice
       is acceptable to the Fiscal Agent.  Such redemption of the Bearer
       Securities must take place on such date, not later than one year
       after the publication of the initial notice of the Company's
       determination of the existence of such certification,
       identification or information reporting requirement.  The Company
       shall not so redeem the Bearer Securities, however, if the
       Company, based on a written opinion of counsel, determines not
       less than 30 days prior to the date fixed for redemption, that no
       such payment would be subject to any requirement described above,
       in which case the Company shall notify the Fiscal Agent, which
       shall give prompt notice of that determination in accordance with
       the Fiscal Agency Agreement and any earlier redemption notice
       shall thereupon be revoked and of no further effect.

                 Notwithstanding the next preceding paragraph, if and so
       long as the certification, identification or information
       reporting requirement referred to in the next preceding paragraph
       would be fully satisfied by payment of United States withholding,
       backup withholding or similar taxes, the Company may elect, prior
       to publication of the notice of redemption and in lieu of
       redemption of the Bearer Securities, to have the provisions of
       this paragraph apply in lieu of the provisions of the next
       preceding paragraph.  In that event, the Company will pay such
       Additional Amounts (without regard to Section 2 hereof) as are
       necessary in order that, following the effective date of such

       requirements, every net payment made outside the United States by
       the Company or a paying agent of the principal of, premium, if
       any, and interest on a Bearer Security or a coupon appertaining
       thereto to a holder who is a United States Alien (without regard
       to a certification, identification or information reporting
       requirement as to the nationality, residence or identity of such
       holder), after deduction for United States withholding, backup
       withholding or similar taxes (other than a tax (i) that would not
       be applicable in the circumstances referred to in the
       parenthetical clause of the first sentence of the next preceding
       paragraph or (ii) are imposed as a result of presentation of such
       Bearer Security or coupon for payment more than 10 days after the
       date on which such payment becomes due and payable or on which
       payment thereof is duly provided for, whichever occurs later),
       will not be less than the amount provided in the Bearer Security
       or the related coupon to be then due and payable.  If the Company
       elects to pay such Additional Amounts and as long as it is
       obligated to pay such Additional Amounts, the Company may
       subsequently redeem the Bearer Securities, at any time, in whole
       but not in part, upon not more than 60 days nor less than 30 days
       notice, given as hereinafter prescribed, at 100% of their
       principal amount, plus accrued interest to date fixed for
       redemption and Additional Amounts, if any.

                 (d)  Each Security is subject to redemption in whole or
       in part (which shall be in a principal amount hereof which is
       U.S. $1,000 or an integral multiple thereof) at the option of the
       holder thereof on any Holder Redemption Date (as defined below)
       at a redemption price equal to 100% of the principal amount
       thereof, together with accrued interest, if a Redemption Event
       shall occur or have occurred.  For purposes hereof a "Redemption
       Event" shall have occurred if the Company's Common Stock (or
       other equity securities into which the Securities are then
       convertible) is neither listed for trading on a United States
       national securities exchange nor approved for trading on an
       established automated over-the-counter trading market in the
       United States.  The "Holder Redemption Date" with respect to any
       Redemption Event shall be the ninetieth day after the later of
       the Exchange Date or the date a Redemption Event has occurred.

                 Notwithstanding the fact that a Security or a portion
       thereof is called for redemption by the Company, each holder of a
       Security desiring to exercise the option for redemption set forth
       in this Section 3(d) shall, as a condition to such redemption, on
       or before the close of business on the fifth day prior to the
       Holder Redemption Date, surrender the Security to be redeemed in
       whole or in part together with the redemption notice hereon duly
       executed at the place or places specified in the notice required
       by Section 3(f) and otherwise comply with the provisions of
       Section 3(g).  A holder of a Security who has tendered a
       redemption notice (i) will be entitled to revoke its election by
       delivering a written notice of such revocation together with the
       holder's non-transferable receipt for such Security to the office
       or agency of the Company designated as the place for the payment
PAGE


       of the Securities to be so redeemed on or before the Holder
       Redemption Date and (ii) will retain the right to convert its
       Securities into shares of Common Stock of the Company to the
       extent set forth in Section 4.

                 (e)  Each Security is subject to redemption in whole or
       in part (which shall be in a principal amount hereof which is
       U.S. $1,000 or an integral multiple thereof) at the option of the
       holder thereof on the Repurchase Date (as defined below) at a
       redemption price equal to 100% of the principal amount thereof,
       together with accrued interest to the Repurchase Date, if a
       Change in Control (as defined below) shall have been determined
       to occur by the Continuing Directors (as defined below), which
       Change in Control shall not have been approved by a majority of
       the Continuing Directors prior to the expiration of the Approval
       Period (as defined below).

                 A Change in Control shall be deemed to have occurred at
       such time or times when (1) any person that acquired any Common
       Stock pursuant to a tender offer becomes the beneficial owner,
       directly or indirectly, of more than 50% of the outstanding
       Common Stock, (2) any person that is the beneficial owner,
       directly or indirectly, of more than 50% of the outstanding
       Common Stock becomes the beneficial owner, directly or
       indirectly, of any additional shares of Common Stock pursuant to
       a tender offer, (3) individuals who constitute the Continuing
       Directors cease for any reason to constitute at least a majority
       of the Board of Directors of the Company, or (4) the Continuing
       Directors shall determine that any other event constitutes an
       effective change in control of the Company.  The Continuing
       Directors shall mean any member of the Board of Directors of the
       Company who was a member of the Board of Directors of the Company
       on January 3, 1996 and any future director of the Company who has
       been nominated or elected by a majority of Continuing Directors
       who are then members of the Board of Directors of the Company.
       The Approval Period shall mean an initial period of 60 days after
       the date on which a Change of Control shall have occurred, plus
       one or more 60 day extensions of such initial or successive
       period which extension shall take effect by vote of a majority of
       the Continuing Directors taken prior to the expiration of the
       applicable 60 day initial or successive period.  The Repurchase
       Date shall be the date that is 50 days after the expiration of
       the Approval Period.

                 The Company will make the determination whether or not
       a Change in Control has occurred, and if one has occurred and it
       shall not have been approved by a majority of the Continuing
       Directors prior to the expiration of the Approval Period, the
       Company shall immediately upon expiration of the Approval Period
       give notice to the Fiscal Agent, stating in the notice the nature
       of the Change in Control, the Repurchase Date and the redemption
       price.

                 Notwithstanding the fact that a Security or a portion
       thereof is called for redemption by the Company, each holder of a
       Security desiring to exercise the option for redemption set forth
       in this Section 3(e) shall, as a condition to such redemption, on
       or before the close of business on the fifth day prior to the
       Repurchase Date, surrender the Security to be redeemed in whole
       or in part together with the redemption notice thereon duly
       executed at the place or places specified in the notice required
       by Section 3(f) and otherwise comply with the provisions of
       Section 3(g).  A holder of a Security who has tendered a
       redemption notice will not be entitled to revoke its election and
       will lose the right to convert its Securities into shares of
       Common Stock of the Company on or before the Repurchase Date.

                 (f)  Notice of redemption will be given by publication
       in Authorized Newspapers (as defined in the Fiscal Agency
       Agreement) on a Business Day (as defined in the Fiscal Agency
       Agreement) in New York City and in London and, if the Securities
       are listed on the Luxembourg Stock Exchange and so long as listed
       thereon, in an Authorized Newspaper in Luxembourg, or, if either
       publication in London or Luxembourg is not practical, in an
       Authorized Newspaper in any country in Western Europe, and by
       mail to holders of Registered Securities, all as provided in the
       Fiscal Agency Agreement.  In the case of a redemption in whole at
       the option of the Company, notice will be given once not more
       than 60 nor less than 30 days prior to the date fixed for
       redemption.  In the case of a partial redemption at the option of
       the Company, notice will be given twice, the first such notice to
       be given not more than 75 nor less than 60 days prior to the date
       fixed for redemption and the second such notice to be given not
       more than 60 nor less than 30 days prior to the date fixed for
       redemption.  In the case of a redemption by the Company at the
       option of a holder of a Security pursuant to Section 3(d) hereof,
       notice will be given by the Fiscal Agent setting forth the
       information described below not later than 10 days after the
       later of the Exchange Date or the occurrence of a Redemption
       Event. In the case of a redemption by the Company at the option
       of a holder of a Security pursuant to Section 3(e) resulting from
       a Change in Control that shall not have been approved by a
       majority of the Continuing Directors prior to the expiration of
       the Approval Period, notice will be given by the Fiscal Agent
       setting forth the information described below not later than 10
       days after the later of the Exchange Date or the expiration of
       the Approval Period.  Neither the failure to give notice nor any
       defect in any notice given to any particular holder of a Security
       shall affect the sufficiency of any notice with respect to other
       Securities.

                 Notices relating to the redemption of Securities
       whether at the option of the Company or the holder hereof shall
       specify: the date fixed for redemption or the Holder Redemption
       Date or the Repurchase Date, as the case may be; the redemption
       price; the date the conversion privilege expires; the place or
       places of payment; and that payment will be made upon
PAGE


       presentation and surrender of the Securities to be redeemed,
       together, in the case of a Bearer Security, with all appurtenant
       coupons, if any, maturing subsequent to the date fixed for
       redemption; and that interest accrued to the date fixed for
       redemption (unless the redemption date is an interest payment
       date) will be paid as specified in such notice; and that, on and
       after said date, interest thereon will cease to accrue.  In the
       case of a redemption by the Company at the option of the holder
       of a Security pursuant to Section 3(d), the notices given by the
       Fiscal Agent informing a holder of such holder's entitlement to
       redeem shall also specify that a holder electing redemption will
       be entitled to revoke its election by delivering a written notice
       of such revocation, together with the holder's non-transferable
       receipt for such Security, to the agency designated by the
       Company as the place for the payment of the Securities to be so
       redeemed not later than the fifth day prior to the Holder
       Redemption Date.  In the case of a redemption in part at the
       option of the Company, notices shall specify the aggregate
       principal amount of Securities to be redeemed and the aggregate
       principal amount of Securities outstanding after such partial
       redemption.  The first notice shall specify the last date on
       which exchanges or transfers of Securities may be made, and the
       second notice shall specify the serial numbers of the Securities
       and the portions thereof called for redemption.  In the case of a
       redemption in whole or in part by the Company, notices shall
       specify the date the conversion privilege expires in accordance
       with Section 4(a) hereof.  Such notices shall also state that the
       conditions precedent, if any, to such redemption have occurred.

                 (g)  If (i) notice of redemption has been given in the
       manner set forth in Section 3(f) hereof with respect to
       Securities to be redeemed at the option of the Company, or (ii)
       notice of redemption has been given by the holder of a Security
       to be redeemed pursuant to Section 3(d) or Section 3(e) hereof,
       the Securities so to be redeemed shall become due and payable on
       the applicable redemption date specified in such notice and upon
       presentation and surrender of the Securities at the place or
       places specified in the notices given by the Company with respect
       to such redemption, together in the case of Bearer Securities
       with all appurtenant coupons, if any, maturing subsequent to the
       redemption date and any related mature defaulted coupons, the
       Securities shall be paid and redeemed by the Company, at the
       places and in the manner and currency herein specified and at the
       redemption price together with accrued interest, if any, to the
       redemption date; provided, however, that interest due in respect
       of coupons maturing on or prior to the redemption date shall be
       payable only upon the presentation and surrender of such coupons
       (at an office or agency located outside of the United States of
       America).  If any Bearer Security surrendered for redemption
       shall not be accompanied by all appurtenant coupons maturing
       after the redemption date and any related mature defaulted
       coupons, such Security may be paid after deducting from the
       amount otherwise payable an amount equal to the face amount of
       all such missing coupons, or the surrender of such missing coupon
PAGE


       or coupons may be waived by the Company and the Fiscal Agent if
       they are furnished with such security or indemnity as they may
       require to save each of them and each other paying agency of the
       Company harmless.  From and after the redemption date, if monies
       for the redemption of Securities shall have been available at the
       principal corporate trust office of the Fiscal Agent for
       redemption on the redemption date, the Securities shall cease to
       bear interest, the coupons for interest appertaining to Bearer
       Securities maturing subsequent to the redemption date shall be
       void, the only right of the holders of such Securities shall be
       to receive payment of the redemption price together with accrued
       interest to the redemption date.  If monies for the redemption of
       the Securities are not made available by the Company for payment
       until after the redemption date, the Securities shall not cease
       to bear interest until such monies have been so made available.

                 (h)  Accrued interest payable on any Registered
       Security that is redeemed will be payable against surrender of
       such Registered Security in the manner described in this Section
       with respect to payments of principal on Registered Securities,
       except that interest on any Registered Security that is redeemed
       on a date after the close of business on any interest Record Date
       and on or before the next succeeding Interest Payment Date, shall
       be paid to the holder of record of such Registered Security on
       the interest Record Date.

            4.   Conversion.

                 (a)  Subject to and upon compliance with the provisions
       of the Fiscal Agency Agreement, a holder of Securities is
       entitled, at its option, at any time on or after the date that is
       the latest of (i) the Exchange Date, (ii) March 15, 1996 and
       (iii) the date of the effectiveness of the Registration Statement
       to be filed by the Company under the Securities Act relating to
       the Common Stock issuable upon conversion of the Restricted
       Securities (the _Registration Date_) and on or before the close
       of business on January 1, 2003, or in the case of a Security or
       portion thereof that is called for redemption by the Company, or
       the holder thereof elects to have such Security or portion
       thereof redeemed by the Company pursuant to Section 3(d) hereof,
       then in respect of such Security or such portion thereof until
       and including, but (unless the Company defaults in making the
       payment due upon redemption) not after, the close of business on
       the 15th day next preceding the date fixed for redemption (or if
       such date is not a business day, as described in Section 11
       hereof in New York City, then the next succeeding business day),
       or in the case of a Security or portion thereof that the holder
       elects to have redeemed by the Company pursuant to Section 3(e)
       hereof, then in respect of such Security or portion thereof until
       and including, but (unless the Company defaults in making the
       payment due upon redemption) not after, the close of business on
       the date the holder makes such election,  to convert such
       Security (or any portion of the principal amount thereof which is
       U.S. $1,000 or an integral multiple thereof), at the principal
PAGE


       amount thereof, or of such portion, into fully paid and
       nonassessable shares ("Conversion Shares")  (calculated as to
       each conversion to the nearest 1/1000 of a share) of common
       stock, par value $1.00 per share of the Company ("Common Stock_),
       at a Conversion Price equal to U.S. $56.70 aggregate principal
       amount of Securities for each Conversion Share (the "Conversion
       Price") (or at the current adjusted Conversion Price if an
       adjustment has been made as provided herein) by surrender of the
       Security, or in the case of a Security submitted for redemption
       pursuant to Section 3(d) or Section 3(e) hereof, satisfactory
       evidence of such submission, together with (i) if a Bearer
       Security, all unmatured coupons and any matured coupons in
       default appertaining thereto, and if a Registered Security (if so
       required by the Company or the Fiscal Agent), instruments of
       transfer in form satisfactory to the Company and the Fiscal
       Agent, duly executed by the registered holder or by his duly
       authorized attorney, and (ii) the conversion notice hereon duly
       executed (x) at the principal corporate trust office of the
       Fiscal Agent, or at such other office or agency of the Company as
       may be designated by it for such purpose in New York City, or (y)
       subject to any laws or regulations applicable thereto and subject
       to the right of the Company to terminate the appointment of any
       such conversion agency, at Chemical Bank, Chemical Bank House,
       125 London Wall, London EC2Y 5AJ, England, and if the Securities
       are listed on the Luxembourg Stock Exchange and so long as listed
       thereon, Banque Internationale a Luxembourg, S.A., 69, Route
       d'Esch, L-1470 Luxembourg, or at such other offices or agencies
       as the Company may designate.

                 (b)  In the case of a conversion after the close of
       business on a Record Date next preceding any interest payment
       date and before the opening of business on such interest payment
       date, the holder of record of a Registered Security at such
       Record Date is to receive an installment of interest on the
       interest payment date.  No payment or adjustment shall be made
       upon any conversion for dividends on the Common Stock delivered
       on conversion.  Except as set forth in the first sentence of this
       subsection (b), accrued interest from the immediately preceding
       interest payment date until the date of conversion (together with
       any Additional Amounts, if any, thereon) will be paid to the
       holder within five business days after presentment for conversion
       on account of any interest accrued on the Securities surrendered
       for conversion, except that interest on Registered Securities
       surrendered for conversion after the close of business on a
       Record Date and before the opening of business on the next
       succeeding interest payment date shall be paid in an amount equal
       to the interest payable on such interest payment date on the
       principal amount being surrendered for conversion.  No fractions
       of shares or scrip representing fractions of shares will be
       issued or delivered on conversion, but instead of any fractional
       interest the Company shall pay a cash adjustment as provided in
       the Fiscal Agency Agreement.  Such conversion shall be so
       affected by the Company, except payment of accrued interest
PAGE


       (together with Additional Amounts, if any, thereon) which will be
       paid by the Paying Agent.

            (c)  (i) In case at any time the Company shall pay or make a
       dividend or other distribution on any class of capital stock of
       the Company in shares of Common Stock, the Conversion Price in
       effect at the opening of business on the day following the date
       fixed for the determination of stockholders entitled to receive
       such dividend or other distribution shall be reduced so that the
       same shall equal the price determined by multiplying such
       Conversion Price by a fraction of which the numerator shall be
       the number of shares of Common Stock outstanding at the close of
       business on the date fixed for such determination and the
       denominator shall be the sum of such number of shares and the
       total number of shares of Common Stock constituting such dividend
       or other distribution, such adjustment to become effective
       immediately after the opening of business on the day following
       the date fixed for such determination.

            (ii) In the case at any time the Company shall (A) subdivide
       its outstanding shares of Common Stock, (B) combine its
       outstanding shares of Common Stock into a smaller number of
       shares, or (C) issue by reclassification of its shares of Common
       Stock (including any such reclassification in connection with a
       consolidation or merger in which the Company is the continuing
       corporation) any shares of capital stock, the Conversion Price in
       effect at the effective date of such subdivision, combination or
       reclassification shall be proportionately adjusted so that the
       holder of any Security surrendered for conversion after such time
       shall be entitled to receive the aggregate number and kind of
       shares which, if such Security had been converted immediately
       prior to such time, the holder would have owned upon such
       conversion and been entitled to receive upon such subdivision,
       combination or reclassification.  Such adjustment shall become
       effective immediately after the effectiveness of such
       subdivision, combination or reclassification.  Such adjustment
       shall be made successively whenever any event listed above shall
       occur.

            (iii)     In case at any time the Company shall fix a record
       date for the issuance of rights or warrants to all holders of its
       Common Stock entitling them to subscribe for or purchase Common
       Stock at a price per share less than the current market price per
       share of Common Stock (determined as provided in paragraph (v) of
       this subsection (c)) on such record date, the Conversion Price in
       effect at the opening of business on the day following such
       record date shall be reduced so that the same shall equal the
       price determined by multiplying such Conversion Price by a
       fraction of which the numerator shall be the number of shares of
       Common Stock outstanding at the close of business on such record
       date plus the number of shares of Common Stock which the
       aggregate of the offering price of the total number of shares so
       offered for subscription or purchase would purchase at such
       current market price per share of Common Stock and the
PAGE


       denominator shall be the number of shares of Common Stock
       outstanding at the close of business on such record date plus the
       number of shares so offered for subscription or purchase, such
       reduction to become effective immediately after the opening of
       business on the day following such record date.  Such reduction
       shall be made successively whenever such a record date is fixed;
       and in the event that such rights or warrants are not so issued,
       the Conversion Price shall again be adjusted to be the Conversion
       Price which would then be in effect if such record date had not
       been fixed.

                 (iv) In case at any time the Company shall fix a record
       date for the making of a distribution, by dividend or otherwise,
       to all holders of its shares if Common Stock, of evidences of its
       indebtedness or assets (including securities, but excluding any
       dividend or distribution referred to in paragraph (i) of this
       subsection (c), any rights or warrants referred to in paragraph
       (iii) of this subsection (c), and any dividend or distribution
       paid in cash out of the retained earnings of the Company), then
       in each such case the Conversion Price in effect after such
       record date shall be determined by multiplying the Conversion
       Price in effect immediately prior to such record date by a
       fraction, of which numerator shall be the total number of
       outstanding shares of Common Stock multiplied by the current
       market price per share of Common Stock (determined as provided in
       paragraph (v) of this subsection (c)) on such record date, less
       the fair market value (as determined by the Board of Directors of
       the Company, whose determination shall be conclusive and
       described in a statement filed with the Fiscal Agent) of the
       portion of the assets or evidences of indebtedness so to be
       distributed, and of which denominator shall be the total number
       of outstanding shares of Common Stock multiplied by such current
       market price per share of Common Stock.  Such adjustment shall be
       made successively whenever such a record date is fixed; and in
       the event that such distribution is not so made, the Conversion
       Price shall again be adjusted to be the Conversion Price which
       would then be in effect if such record date has not been fixed.

                 (v)  For the purpose of any computation under
       paragraphs (iii) and (iv) of this subsection (c), the current
       market price per share of Common Stock on any date shall be
       deemed to be the average of the Closing Prices (as defined below)
       for the 15 consecutive trading days upon which the principal
       trading market for the Common Stock is open and selected by the
       Company commencing not less than 20 nor more than 30 days before
       the day in question.  The "Closing Price" for any day shall be
       the last reported sales prices regular way or, in case no such
       reported sale takes place on such day, the average of the
       reported closing bid and asked prices regular way, in either case
       on the New York Stock Exchange or, if the Common Stock is not or
       admitted to trading on such exchange, on the principal national
       securities exchange on which the Common Stock is listed or
       admitted to trading or, if not listed or admitted to trading on
       any national securities exchange, the closing sale price quoted
PAGE


       on the Nasdaq National Market, or if not so quoted, as determined
       by the Company.

                 (vi) The Company may make such adjustments in the
       Conversion Price, in addition to those required by paragraphs
       (i), (ii) and, (iii) selected by the Company of this section, as
       it considers to be advisable in order that any event treated for
       United States Federal income tax purposes as a dividend of stock
       or stock rights shall not be taxable to the recipients.

                 (vii)     No adjustment in the Conversion Price shall
       be required unless such adjustment would require an increase or
       decrease of at least U.S. $.25 in such Conversion Price;
       provided, however, that any adjustment which by reason of this
       paragraph (vii) is not required to be made shall be carried
       forward and taken into account in any subsequent adjustment.  All
       calculations under this subsection (c) shall be made to the
       nearest cent or to the nearest 1/1000 of a share, as the case may
       be.

                 (viii)    In the event that the Company shall
       distribute rights pro rata to holders of Common Stock pursuant to
       the Rights Agreement, dated as of May 4, 1988, between the
       Company and the First National Bank of Boston, as Rights Agent,
       or any similar plan (_Rights_) the Company shall make proper
       provision so that each holder of a Security who converts such
       Security (or any portion thereof) after the record date for such
       distribution and prior to the expiration or redemption of the
       Rights shall be entitled to receive upon such conversion, in
       addition to the Conversion Shares, a number of Rights to be
       determined as follows:  (i) if such conversion occurs on or prior
       to the date for the distribution to the holders of Rights of
       separate certificates evidencing such Rights (the _Distribution
       Date_), the same number of Rights to which a holder of a number
       of shares of Common Stock equal to the number of Conversion
       Shares is entitled at the time of such conversion in accordance
       with the terms and provisions of and applicable to the Rights;
       and (ii) if such conversion occurs after the Distribution Date,
       the same number of Rights to which a holder of the number of
       shares of Common Stock into which the principal amount of the
       Security so converted was convertible immediately prior to the
       Distribution Date would have been entitled on the Distribution
       Date in accordance with the terms and provisions of and
       applicable to the Rights; provided, however, that if after the
       Distribution Date with respect to such Rights converting Holders
       of Securities are not entitled to receive the Rights that would
       otherwise be attributable (but for the date of conversion) to
       their respective Conversion Shares or such Rights are not issued
       to them upon conversion for any reason, then adjustment of the
       Conversion Price shall be made under paragraph (iii) and this
       subsection (c), except the Distribution Date with respect to such
       Rights shall be substituted as _the record date for the issuance
       of rights_; provided, further, that if such an adjustment is made
       and such Rights are later redeemed, invalidated or terminated,
PAGE


       then a corresponding reversing adjustment of the Conversion Price
       shall be made to the Conversion Price, on an equitable basis, to
       take account of such event.

                 (d)  Whenever the Conversion Price is adjusted and in
       the event of certain other corporate actions, as herein provided,
       the Company shall give notice, all as provided in the Fiscal
       Agency Agreement.

                 (e)  The Company shall file, as soon as practicable
       following the Closing Date, a shelf registration statement with
       the United States Securities and Exchange Commission covering the
       resale of the shares of Common Stock issuable upon conversion of
       the Restricted Securities (_Registrable Securities_); provided
       that any holder of any Restricted Securities or Registrable
       Securities shall not sell any shares pursuant to such
       registration statement unless and until it provides to the
       Company such information as the Company may reasonably request
       for use in connection with the identification of such holder as a
       selling stockholder in such registration statement, or any
       prospectus included therein, and no such sale shall be made by
       such holder pursuant to such registration statement unless and
       until such information is included by the Company in such
       registration statement or prospectus.  The Company shall in good
       faith use its best efforts and at its cost to cause such
       registration statement to be declared effective as promptly as
       practicable thereafter and to include in such registration
       statement the information provided by a holder as a selling
       stockholder and shall notify the Fiscal Agent of the
       effectiveness thereof and agrees to use its best efforts to (i)
       cause all registrations with, and to obtain any approvals by, any
       governmental authority under any Federal or state law of the
       United States that may be required in connection with the
       conversion of the Securities into Common Stock and the resale
       thereof, (ii) maintain the effectiveness of such registrations
       until the earlier of (a) three years from the date of the Fiscal
       Agency Agreement, or (b) the date that Rule 144(k) under the
       Securities Act is available for the resale of the shares of
       Common Stock issuable upon conversion of the Restricted
       Securities (or other securities issuable upon conversion of the
       Securities) and (iii) to list the shares of Common Stock required
       to be issued or delivered upon conversion of Securities (or other
       securities issuable upon conversion of the Securities) prior to
       such issue or delivery on such national securities exchange or
       automated over-the-counter trading market where such Common Stock
       is listed or traded at the time of such delivery. The Company
       shall, without limitation as to time, indemnify and hold
       harmless, to the fullest extent permitted by law, each holder of
       Registrable Securities, the officers, directors and agents and
       employees of each of them, each person who controls such holder
       (within the meaning of Section 15 of the Securities Act or
       Section 20 of the Securities Exchange Act of 1934, as amended)
       and the officers, directors, agents and employees of any such
       controlling person, from and against all losses, claims, damages,
PAGE


       liabilities, costs (including, without limitation, the costs of
       preparation and attorneys' fees) and expenses (collectively,
       _Losses_), as incurred, arising out of or based upon any untrue
       or alleged untrue statement of a material fact contained in any
       such registration statement, or related prospectus or in any
       amendment or supplement thereto, or arising out of or based upon
       any omission or alleged omission to state therein a material fact
       required to be stated therein or necessary to make the statements
       therein not misleading, except insofar as the same are based
       solely upon information, if any, furnished in writing to the
       Company by such holder expressly for use therein; provided, that
       the Company shall not be liable to any holder of Registrable
       Securities to the extent that any such Losses arise out of or are
       based upon an untrue statement or alleged untrue statement or
       omission or alleged omission made in any preliminary prospectus
       if either (a)(i) such holder failed to send or deliver as
       required a copy of the final prospectus with or prior to the
       delivery of written confirmation of the sale by such holder of a
       Registrable Security to the person asserting the claim from which
       such Losses arise and (ii) the prospectus would have completely
       corrected such untrue statement or alleged untrue statement or
       such omission or alleged omission; or (b)(i) such untrue
       statement or alleged untrue statement, omission or alleged
       omission is completely corrected in an amendment or supplement to
       the prospectus and (ii) having previously been furnished by or on
       behalf of the Company with copies of the prospectus as so amended
       or supplemented, such holder thereafter fails to deliver as
       required such prospectus as so amended or supplemented, prior to
       or concurrently with the sale of a Registrable Security to the
       person asserting the claim from which such Losses arise. Promptly
       after receipt by an indemnified party under this Paragraph (e) of
       notice of any claim or the commencement of any action, the
       indemnified party shall, if a claim in respect thereof is to be
       made against the Company under this Paragraph (e) notify the
       Company in writing of the claim or the commencement of that
       action; provided, however, that the failure to notify the Company
       shall not relieve it from any liability which it may have to an
       indemnified party otherwise than under this Paragraph (e).  If
       any such claim or action shall be brought against an indemnified
       party, and it shall notify the Company thereof, the Company shall
       be entitled to participate therein and, to the extent that it
       wishes, to assume the defense thereof with counsel reasonably
       satisfactory to the indemnified party.  After notice from the
       Company to the indemnified party of its election to assume the
       defense of such claim or action, the Company shall not be liable
       to the indemnified party under this Paragraph (e) for any legal
       or other expenses subsequently incurred by the indemnified party
       in connection with the defense thereof; provided, however, if the
       defendants in any such action include both an indemnified party
       and the Company and the indemnified party shall have reasonably
       concluded that there may be legal defenses available to it and
       for other indemnified parties that are different from or
       additional to those available to the Company, the indemnified
       party or parties under this Paragraph (e) shall have the right to
PAGE


       employ not more than one counsel to represent them and, in that
       event, the reasonable fees and expenses of not more than one such
       separate counsel shall be paid by the Company.  The Company shall
       not be liable for any settlement effected without its written
       consent of any claim or action.

                 (f)  The Company shall, at all times, have reserved and
       available, free from preemptive rights, out of its authorized but
       unissued shares of Common Stock, for the purpose of effecting the
       conversion of Securities, the full number of shares of Common
       Stock then issuable upon the conversion of all Securities (based
       on the aggregate principal amount of Securities outstanding).
       The Company covenants that all shares of Common Stock which may
       be issued or delivered upon conversion of Securities will upon
       issuance be fully paid and nonassessable.

                 (g)  Subject to the rights of the holders pursuant to
       Section 3(e) hereof, in case of any consolidation with, or merger
       of the Company into, any other corporation, or in case of any
       merger of another corporation into the Company (other than a
       merger which does not result in any reclassification, conversion,
       exchange or cancellation of outstanding shares of Common Stock of
       the Company), or in case of any sale or transfer of all or
       substantially all of the assets of the Company (which shall not
       include the sale or transfer of any portion of the assets of the
       Company to any corporation which, immediately following such
       transfer is at least 51% owned by the Company, provided that such
       sale or transfer does not result in the reclassification,
       conversion, exchange or cancellation of outstanding shares of
       Common Stock of the Company), the corporation formed by such
       consolidation or resulting from such merger or which acquires
       such assets, as the case may be, shall execute and deliver to the
       Fiscal Agent an amendment to the Fiscal Agency Agreement
       providing that the holder of each Security shall have the right
       during the period such Security shall be convertible as specified
       in section (a) hereof to convert such Security only into the kind
       and amount of securities, cash and other property receivable upon
       such consolidation, merger, sale or transfer by a holder of the
       number of shares of Common Stock of the Company into which such
       Security might have been converted immediately prior to such
       consolidation, merger, sale or transfer assuming, if such
       consolidation, merger, sale or transfer is prior to the period
       such Security shall be convertible as specified in subsection (a)
       hereof, that the Securities were convertible at such time at the
       initial Conversion Price as adjusted from November 28, 1995 to
       such time pursuant to paragraphs (i), (ii), (iii), (iv) and (vi)
       of subsection (c) hereof.  Such amendment shall provide for
       adjustments which, for events subsequent to the effective date of
       such amendment, shall be as nearly equivalent as may be
       practicable to the adjustments provided for herein.  The above
       provisions of this subsection shall similarly apply to successive
       consolidations, mergers, sales or transfers.

            5.   Events of Default.  In the event that any of the
       following ("Events of Default_) shall occur and be continuing:

                 (a)  the Company shall fail to pay when due the
       principal of, or premium, if any, on any of the Securities
       whether at maturity or upon redemption or otherwise; or

                 (b)  the Company shall fail to pay any installment of
       interest or any required payment of any Additional Amounts (as
       described in Section 2 hereof) on any of the Securities for a
       period of 10 days after the date when due; or

                 (c)  the Company shall fail duly to perform or observe
       any other term, covenant or agreement contained in any of the
       Securities or in the Fiscal Agency Agreement for a period of 60
       days after the date on which written notice of such failure,
       requiring the Company to remedy the same, shall first have been
       given to the Company and the Fiscal Agent by the holders of at
       least 25% in aggregate principal amount of the Securities at the
       time outstanding; provided, however, that in the event the
       Company shall within the aforesaid period of 60 days commence
       legal action in a court of competent jurisdiction seeking a
       determination that the Company had not failed duly to perform or
       observe the term or terms, covenant or covenants or agreement or
       agreements specified in the aforesaid notice, such failure shall
       not be an Event of Default unless the same continues for a period
       of 10 days after the date of any final determination to the
       effect that the Company had failed to duly perform or observe one
       or more of such terms, covenants or agreements; or

                 (d)  a court having jurisdiction in the premises shall
       enter a decree or order for relief in respect of the Company in
       an involuntary case or proceeding under any applicable
       bankruptcy, insolvency, reorganization or other similar law now
       or hereafter in effect, or appointing a receiver, liquidator,
       assignee, custodian, trustee, sequestrator (or similar official)
       of the Company or for any substantial part of the property of it
       or ordering the winding-up or liquidation of the affairs of it
       and such decree or order shall remain unstayed and in effect for
       a period of 20 consecutive days; or

                 (e)  the Company shall commence a voluntary case or
       proceeding under any applicable bankruptcy, insolvency,
       reorganization or other similar law now or hereafter in effect,
       or shall consent to the entry of an order for relief in an
       involuntary case under any such law, or shall consent to the
       appointment of or taking possession by a receiver, liquidator,
       assignee, trustee, custodian, sequestrator (or similar official)
       of the Company or for any substantial part of its property, or
       shall make any general assignment for the benefit of creditors,
       or shall admit in writing its inability to pay its debts as they
       become due or shall take any corporate action in furtherance of
       any of the foregoing; or
PAGE


                 (f)  an event of default, as defined in any indenture
       or instrument evidencing or under which the Company shall have at
       least $25,000,000 outstanding (or its equivalent in another
       currency), in aggregate principal amount of indebtedness for
       borrowed money, shall happen and be continuing and such default
       shall involve the failure to pay the principal of such
       indebtedness (or any part thereof), when due and payable after
       the expiration of any applicable grace period with respect
       thereto, or such indebtedness shall have been accelerated so the
       same shall be or become due and payable prior to the date on
       which the same would otherwise have become due and payable, and
       failure to pay shall not have been cured by the Company within 20
       days after such failure or such acceleration shall not be
       rescinded or annulled within 20 days after notice thereof shall
       have first been given to the Company; provided that if such event
       of default under such indenture or instrument shall be remedied
       or cured by the Company or waived by the holders of such
       indebtedness, then the Event of Default hereunder by reason
       thereof shall be deemed likewise to have been thereupon remedied,
       cured or waived without further action upon the part of any of
       the holders of Securities; then the holder of this Security may,
       at such holder's option, declare the principal of this Security
       and the interest accrued hereon (and Additional Amounts under
       Section 2 hereof, if any, thereon) to be due and payable
       immediately by written notice to the Company and the Fiscal
       Agent, and if any such Event of Default shall continue at the
       time of receipt of such written notice, the principal of this
       Security and the interest accrued hereon (and Additional Amounts,
       if any, hereon) shall become immediately due and payable, subject
       to the proviso of subsection (c) of this Section 5. Upon payment
       of such amount of principal, premium, if any, and interest (and
       Additional Amounts pursuant to Section 2 hereof, if any), all of
       the Company's obligations in respect of payment of principal of,
       premium, if any, and interest on (and Additional Amounts, if any,
       on) this Security shall terminate.  Interest on overdue
       principal, premium, if any, and interest (and Additional Amounts,
       if any) shall accrue from the date on which such principal,
       premium, if any, and interest (and Additional Amounts, if any)
       were due and payable to the date such principal, premium, if any,
       and interest (and Additional Amounts, if any) are paid or duly
       provided for, at the rate borne by the Securities (to the extent
       payment of such interest shall be legally enforceable).  Any
       acceleration of this Security pursuant to this Section 5 shall
       not affect the subordination provisions of Section 7 hereof.

                 If an Event of Default, as defined in this Section 5,
       with respect to the Securities, or an event which would, with the
       passing of time or the giving of notice, or both, be an Event of
       Default, shall occur and be continuing, the Company shall within
       five Business Days of becoming aware thereof notify the Fiscal
       Agent in writing of such Event of Default, and the Fiscal Agent
       shall thereupon promptly notify all of the holders of the
       Securities of such Event of Default.
PAGE


            6.   Merger, Consolidation, Sale, Conveyance or Assumption.

                 (a)  Subject to the rights of the holder pursuant to
       Section 3(e) hereof, the Company will not merge or consolidate
       with, or sell or convey all or substantially all of its assets
       to, any other corporation, unless (i) either (A) the Company
       shall be the surviving corporation in the case of a merger, (B)
       the assets sold or conveyed shall be owned by a corporation
       which, immediately following such sale or conveyance, is at least
       51% owned by the Company, provided that such sale or conveyance
       does not result in the reclassification, conversion, exchange or
       cancellation of outstanding shares of Common Stock of the
       Company, or (C) (I) the surviving, resulting or transferee
       corporation shall expressly assume the due and punctual payment
       (including Additional Amounts pursuant to Section 2 hereof, if
       any) of all the Securities, according to their tenor, and the due
       and punctual performance of all of the covenants and obligations
       of the Company under the Securities, the coupons and the Fiscal
       Agency Agreement, by supplemental agreement reasonably
       satisfactory to the Fiscal Agent and (II) the Fiscal Agent shall
       have received the documentation required in the context by the
       Fiscal Agency Agreement, (ii) the surviving, resulting or
       transferee corporation, if not organized and validly existing
       under the laws of the United States, shall expressly agree to
       make payments under the Securities free of any deduction or
       withholding for any and all then existing or future withholding
       taxes, levies, imposts and charges whatsoever imposed by or for
       the account of the jurisdiction where such successor corporation
       is generally subject to taxation (or any political subdivision or
       taxing authority thereof or therein) in a manner equivalent to
       that set forth herein, subject to the exceptions contained in
       such forms of the Securities, and (iii) the Company or such
       successor corporation, as the case may be, shall not, immediately
       after such merger, consolidation, sale or conveyance, be in
       default in the performance of any covenants or obligations of the
       Company under the Securities or the Fiscal Agency Agreement.

                 (b)  Upon any merger, consolidation, sale, conveyance
       or assumption as provided in Section 6(a), the successor or
       assuming corporation shall succeed to and be substituted for, and
       may exercise every right and power of and be subject to all the
       obligations of, the Company under the Securities and Fiscal
       Agency Agreement, with the same effect as if such successor or
       assuming corporation had been named as the Company therein and
       herein and the Company shall be released from its liability as
       obligor under the Securities and Fiscal Agency Agreement;
       provided that any successor or assuming corporation shall have
       the right to redeem the Securities pursuant to Section 3(b)
       hereof only as a result of circumstances which occur subsequent
       to such merger, consolidation, sale, conveyance or assumption and
       as a result of which the Company would have had such right if the
       Company had remained the obligor on the Securities.

            7.   Agreement of Subordination of Securities.
PAGE


                 (a)  The Company, for itself, its successors and
       assigns, covenants and agrees, and each holder of Securities and
       coupons by his acceptance thereof, likewise covenants and agrees,
       that the payment of the principal of, premium, if any, and
       interest and Additional Amounts (pursuant to Section 2 hereof) on
       each and all of the Securities and coupons is hereby expressly
       subordinated, to the extent and in the manner hereinafter set
       forth, in right of payment to the prior payment in full of all
       Senior Indebtedness of the Company (as defined below).

                 "Senior Indebtedness of the Company_ or _Senior
       Indebtedness_ shall mean the principal of, premium, if any, and
       interest on and all other amounts due on or with respect to the
       following whether outstanding at the date of execution of the
       Fiscal Agency Agreement or thereafter incurred or created:

                 (i)  indebtedness of the Company for money borrowed by
       the Company (excluding the Securities, but including, without
       limitation, purchase money obligations), whether or not evidenced
       by debentures, bonds, notes or other corporate debt securities or
       similar instruments issued by the Company (including the
       Company's obligations with respect to its 5% Senior Convertible
       Debentures due 2001 and its 4-5/8% Senior Convertible Debentures

       subordinate, at least to the extent provided in this Section 7
       with respect to the Securities, to the payment of all Senior
       Indebtedness of the Company, provided that the rights of the
       holders of Senior Indebtedness of the Company are not altered by
       such reorganization or readjustment.  For the purposes of this
       Section 7, no consolidation, merger, conveyance or transfer made
       pursuant to the provisions of Section 6 shall be deemed to be a
       liquidation, reorganization, dissolution or other winding up of
       the Company.

                 (ii) If under the circumstances set forth in paragraph
       (i) of this subsection, and notwithstanding the provisions

       7 with respect to the Securities, to the payment of all Senior
       Indebtedness of the Company, provided that the rights of the
       holders of Senior Indebtedness of the Company are not altered by
       such reorganization or readjustment), shall be received by the
       holders of the Securities before all Senior Indebtedness of the
       Company is paid in full, such payment or distribution shall be
       paid over to the holders of Senior Indebtedness of the Company,
       ratably, for application to the payment of all Senior
       Indebtedness of the Company remaining unpaid until all Senior
       Indebtedness of the Company shall have been paid in full, after
       giving effect to any concurrent payment or distribution to the
       holders of such Senior Indebtedness of the Company.

                 (iii)     Upon any distribution of assets of the
       Company referred to in this Section, the holders of Securities
       shall be entitled to rely upon any final order or decree of a
       court of competent jurisdiction in which such dissolution,
       winding up, liquidation or reorganization proceedings are
       pending, and the holders of Securities shall be entitled to rely
       upon a certificate of the liquidating trustee or agent or other
       person making any distribution to the holders of Securities for
       the purpose of ascertaining the persons entitled to participate
       in such distribution, the holders of the Senior Indebtedness of
       the Company and other indebtedness of the Company, the amount
PAGE


       thereof or payable thereon, the amount or amounts paid or
       distributed thereon and all other facts pertinent thereto or to
       this Section.

                 (c)  (i) Upon the maturity of any Senior Indebtedness
       of the Company by lapse of time, acceleration or otherwise, all
       principal thereof (and premium, if any) and interest due thereon,
       including interest thereon accruing after the commencement of any
       proceeding of the type referred to in paragraph (i) of Section
       7(b) above, and all other amounts due on or with respect thereto,
       shall first be paid in full, or such payment duly provided for in
       cash, before any payment, directly or indirectly, is made on
       account of the principal of, premium, if any, or interest and
       Additional Amounts (pursuant to Section 2 hereof) on the
       Securities or coupons.

                 (ii) Upon the happening of an event of default with
       respect to any Senior Indebtedness of the Company, as defined
       therein or in the instrument under which it is outstanding
       permitting the holders to accelerate the maturity thereof, then,
       unless and until such event of default shall have been cured or
       waived or shall have ceased to exist, no payment shall be made by
       the Company, directly or indirectly, on account of the principal
       of, premium, if any, or interest and Additional Amounts (pursuant
       to Section 2 hereof) on the Securities or coupons.

                 (d)  In case cash, securities or other property
       otherwise payable or deliverable to the holders of the Securities
       shall have been applied, pursuant to Section 7(b) or 7(c), to the
       payment of Senior Indebtedness of the Company, then, upon the
       payment in full of all Senior Indebtedness of the Company, the
       holders of the Securities shall be subrogated to any rights of
       any holders of Senior Indebtedness of the Company to receive any
       further payment or distributions applicable to Senior
       Indebtedness of the Company until the principal of, premium, if
       any, and interest and Additional Amounts (pursuant to Section 2
       hereof) on the Securities shall have been paid in full, and such
       payments or distributions received by the holders of the
       Securities and coupons, by reason of such subrogation, of cash,
       securities or other property which otherwise would be paid or
       distributed to the holders of Senior Indebtedness of the Company
       shall, as between the Company and its creditors other than the
       holders of Senior Indebtedness of the Company, on the one hand,
       and the holders of the Securities, on the other hand, be deemed
       to be a payment by the Company on account of Senior Indebtedness
       of the Company and not on account of the Securities.

                 (e)  No present or future holder of any Senior
       Indebtedness of the Company shall be prejudiced in any way in the
       right to enforce the subordination of the Securities by any act
       or failure to act on the part of the Company.  The provisions of
       this Section are solely for the purpose of defining the relative
       rights of the holders of Senior Indebtedness of the Company, on
       the one hand, and the holders of the Securities, on the other
PAGE


       hand, against the Company and its assets, and nothing contained
       in this Section shall impair, as between the Company and the
       holder of any Security, the obligation of the Company, which is
       unconditional and absolute, to pay to the holder thereof, the
       principal thereof, premium, if any, and interest and Additional
       Amounts (pursuant to Section 2 hereof) thereon as and when the
       same shall become due and payable in accordance with the terms
       thereof, or prevent the holder of any Security, upon default
       hereunder or under such Security, from exercising all rights,
       powers and remedies otherwise provided herein or therein or by
       applicable law, all subject to the rights of the holders of
       Senior Indebtedness of the Company under this Section to receive
       cash, property or securities otherwise payable or deliverable to
       the holders of the Securities and coupons.

                 (f)  Nothing contained in this Section or in any of the
       Securities shall prevent at any time, except under the conditions
       described in Sections 7(b) and (c) hereof or during the pendency
       of any dissolution, winding up, liquidation or reorganization
       proceedings therein referred to, the Company from making payments
       at any time of principal of, premium of, if any, or interest or
       Additional Amounts (pursuant to Section 2 hereof) on the
       Securities.  Nothing contained in this Section shall prevent
       conversions of Securities.


                 8.   Replacement, Transfer and Exchange of Securities.

                 (a)  In case any Security (including any coupons
       appertaining thereto) shall at any time become mutilated,
       destroyed, stolen or lost and such Security or evidence of the
       loss, theft or destruction thereof (together with the indemnity
       hereinafter referred to and such other documents or proof as may
       be required) shall be delivered to the Fiscal Agent, a new
       Security of like tenor and date with appropriate interest
       coupons, if any, will be issued by the Company in exchange for
       the Security so mutilated, or in lieu of the Security so
       destroyed, stolen or lost, but, in the case of a destroyed,
       stolen or lost Security only upon receipt of evidence
       satisfactory to the Fiscal Agent and the Company that such
       Security was destroyed, stolen or lost, and if required by the
       Fiscal Agent or the Company, upon receipt also of indemnity
       satisfactory to the Fiscal Agent and the Company.  All expenses
       and reasonable charges associated with procuring such indemnity
       and with the preparation, authentication and delivery of a new
       Security shall be borne by the owner of the Security so
       mutilated, destroyed, stolen or lost.

                 (b)  As provided in the Fiscal Agency Agreement and
       subject to certain limitations therein set forth, Bearer
       Securities (with all unmatured and matured defaulted coupons
       appertaining thereto) are exchangeable at, subject to applicable
       laws and regulations, the offices of the paying agencies in
       London and, if the Securities are listed on the Luxembourg Stock
PAGE


       Exchange and so long as listed thereon, Luxembourg or as
       designated by the Company for such purpose pursuant to the Fiscal
       Agency Agreement, for an equal aggregate principal amount of
       Registered Securities in the denominations of $1,000 and integral
       multiples thereof without coupons and/or Bearer Securities of
       authorized denominations, and Registered Securities are
       exchangeable at the Corporate Trust Office of the Fiscal Agent in
       New York City or, subject to applicable laws and regulations, the
       offices of the paying agencies in London and, if the Securities
       are listed on the Luxembourg Stock Exchange and so long as listed
       thereon, Luxembourg or as designated by the Company for such
       purpose pursuant to the Fiscal Agency Agreement, for an equal
       aggregate principal amount of Registered Securities of authorized
       denominations as requested by the holder surrendering the same.
       Registered Securities will not be exchangeable for Bearer
       Securities.  The Company shall not be required (a) to exchange
       Bearer Securities for Registered Securities during the period
       between the close of business on each June 15 and December 15 and
       the opening of business on the next succeeding interest payment
       date or (b) to exchange Bearer Securities for Registered
       Securities, if as a result, the Company would incur adverse
       consequences under United States Federal income tax laws in
       effect of the time of exchange, or (c) in the event of a
       redemption in part, (i) to register the transfer of Registered
       Securities or to exchange Bearer Securities for Registered
       Securities for a period of 15 days immediately preceding the date
       notice is given identifying the serial numbers of the Securities
       called for such redemption; (ii) to register the transfer or
       exchange of any such Registered Securities, or portion thereof,
       called for redemption; or (iii) to exchange any such Bearer
       Securities called for redemption; provided, however, that a
       Bearer Security called for redemption may be exchanged for a
       Registered Security that is simultaneously surrendered, with
       written instruction for payment on the date fixed for redemption,
       unless the date fixed for redemption is during the period between
       the close of business on each June 15 and December 15 and the
       close of business on the next succeeding interest payment date,
       in which case such exchange may only be made prior to the close
       of business on each June 15 and December 15 immediately preceding
       the date fixed for redemption.  In the event of redemption or
       conversion of a Security in part only, a new Security or
       Securities for the unredeemed or unconverted portion hereof will
       be issued in the name of the holder thereof.

                 (c)  The costs and expenses of effecting any exchange
       or registration of transfer pursuant to the foregoing provisions,
       except for the expenses of delivery by other than regular mail
       (if any) and except, if the Company shall so require, the payment
       of a sum sufficient to cover any tax or other governmental charge
       or insurance charges that may be imposed in relation thereto,
       will be borne by the Company.

                 (d)  The Company has initially appointed as registrar
       and transfer agent the Fiscal Agent acting through the Corporate
PAGE


       Trust Office in New York.  The Company has also initially
       appointed Banque Internationale a Luxembourg as a transfer agent,
       subject to the listing of the Securities on the Luxembourg Stock
       Exchange.  The Company may at any time terminate the appointment
       of the registrar and transfer agent and appoint additional or
       other registrars and transfer agents or approve any change in an
       office through which the registrar and transfer agent acts;
       provided that, until all of the Securities have been delivered to
       the Fiscal Agent for cancellation, or monies sufficient to pay
       the Securities have been made available for payment and either
       paid or returned to the Company as provided in the Securities,
       the Company will maintain a registrar and transfer agent in the
       City of New York in the United States.

                 (e)  For purposes of the provisions of this Security
       and the Fiscal Agency Agreement, any Security authenticated and
       delivered pursuant to the Fiscal Agency Agreement shall, as of
       any date of determination, be deemed to be "outstanding", except
       for:

                      (i)  Securities previously canceled by the Fiscal
       Agent or delivered to the Fiscal Agent for cancellation;

                      (ii) Securities which have been called for
       redemption by the Company in accordance with Section 3 hereof or
       which have become due and payable at maturity or otherwise and
       with respect to which monies sufficient to pay the principal
       thereof and interest thereon (including Additional Amounts, if
       any) shall have been made available to the Fiscal Agent; or

                      (iii)     Securities in lieu of or in substitution
       for which other Securities have been authenticated and delivered
       pursuant to the Fiscal Agency Agreement;

       provided, however, that in determining whether the holders of the
       requisite principal amount of outstanding Securities are present
       at a meeting of holders of Securities for quorum purposes or have
       given any request, demand, authorization, direction, notice,
       consent or waiver hereunder, Securities owned by the Company or
       any subsidiary thereof shall be disregarded and deemed not to be
       outstanding.

            9.   Modifications and Amendments.

                 (a)  Without the consent of any holders of Securities
       or coupons, modifications of or amendments to the Fiscal Agency
       Agreement or the Terms and Conditions of the Securities may be
       made for any of the following purposes:

                      (i)  to evidence the succession of another
       corporation to the Company and the assumption by any such
       successor of the covenants of the Company in the Fiscal Agency
       Agreement or the Securities;

                      (ii) to add to the covenants of the Company for
       the benefit of the holders of Securities or related coupons, or
       to surrender any right or power herein conferred upon the
       Company;

                      (iii)     to permit payment of principal of,

       on Bearer Securities in the United States, provided that such
       payment is permitted by
       United States tax laws and regulations then in effect;

                      (iv) to make provision with respect to the
       conversion rights and redemption rights of holders of Securities

       substantially all of the assets of the Company;

                      (v)  to cure any ambiguity, to correct or
       supplement any defective provision in the Fiscal Agency Agreement
       which may be inconsistent with any other provision therein, or to
       make any other provisions with respect to matters or questions
       arising under this Security or the Fiscal Agency Agreement,
       provided such action pursuant to this clause (v) will not
       materially adversely affect the interests of the holders of
       Securities or related coupons; or

                      (vi) to increase the principal amount of

       Agreement; or 

                      (vii)     to delete the agreement of subordination
       contained in Section 7 hereof and any other references thereto.

                 (b)  Modifications and amendments to the Fiscal Agency
       Agreement or to the Terms and Conditions of the Securities may be
       made, and future compliance with or past default by the Company
       under any of the provisions thereof may be waived, with the
       written consent of the holders of not less than a majority in
       aggregate principal amount of the Securities at the time
       outstanding (excluding for purposes of this calculation the
       aggregate principal amount of Securities held by the Company or
       any of its subsidiaries), or of such lesser percentage as may act
       at a meeting of holders of Securities held in accordance with the
       provisions set forth herein; provided that no such modification,
       amendment or waiver may, without the consent of the holder of
       each such Security affected thereby:

                      (i)  waive a default in the payment of the

       which any Security or any premium or interest thereon is payable,
       or, except as otherwise permitted or contemplated by the
       provisions concerning corporate reorganizations, adversely affect
       the right to redeem (pursuant to Section 3(d) or Section 3(e)
       hereof) or convert any Securities as provided in Sections 3 and
       4, respectively;

                      (iii)     reduce the requirements of Section 10
       hereof for the adoption of a resolution of the quorum required at
       any meeting of holders of Securities at which a resolution is
       adopted, or reduce the percentage in principal amount of the
       outstanding Securities the consent of whose holders is required
       for any amendment or modification of the Fiscal Agency Agreement
       or the Terms and Conditions of the Securities or the consent of
       whose holders is required for any waiver (of compliance with

                      (v)  modify any of the provisions of this section
       except to increase any such percentage or to provide that certain
       other provisions of the Fiscal Agency Agreement or the Securities
       cannot be modified or waived without the consent of the holder of
       each outstanding Security affected thereby.

       It shall not be necessary for any act of holders of Securities
       under this Section to approve the particular form of any proposed
       amendment, modification or waiver, but it shall be sufficient if
       such act shall approve the substance thereof.  Any modifications,
       amendments or waivers to the Fiscal Agency Agreement or to these
       Terms and Conditions will be conclusive and binding on all
       holders of the Securities and any coupons appertaining thereto,
       whether or not they have given such consent or were present at
       such meeting and whether or not notation of such modifications,
       amendments or waivers is made upon the Securities or coupons, and
       on all future holders of Securities and coupons.  Any instrument
       given by or on behalf of any holder of a Security in connection
       with any consent to any such modification, amendment or waiver
       will be irrevocable once given and will be conclusive and binding
       on all subsequent holders of such Security and coupons
       appertaining thereto.

            10.  Meetings and Votes of Holders.

                 (a)  A meeting of holders of Securities may be called
       at any time and from time to time pursuant to this Section for
       any of the following purposes: (i) to give any notice to the
       Company or to the Fiscal Agent, or to give any directions to the
       Fiscal Agent, or to consent to the waiving of any default
       hereunder and its consequences, or to take any other action
       authorized to be taken by holders of Securities pursuant to these
       Terms and Conditions; or (ii) to take any other action authorized
       to be taken by or on behalf of the holders of any specified
       aggregate principal amount of the Securities under any other
       provision of the Fiscal Agency Agreement, under applicable law or
       under these Terms and Conditions.

                 (b)  Meetings of holders of Securities may be held at
       such place or places in New York City or London as the Fiscal
       Agent or, in case of its failure to act, the Company or the
       holders calling the meeting shall from time to time determine.

                 The Fiscal Agent may at any time call a meeting of
       holders of the Securities to be held at such time and at such
       place in any of such designated locations as the Fiscal Agent
       shall determine.  Notice of every meeting of holders shall be
       made as specified in the Fiscal Agency Agreement.

                 In case at any time the Company or the holders of at
       least 25% in aggregate principal amount of the Securities shall
       have requested the Fiscal Agent to call a meeting of the holders,
       by written request setting forth in reasonable detail the action
       proposed to be taken at the meeting, and the Fiscal Agent shall
       not have given the first notice of such meeting within 21 days
       after receipt of such request or shall not thereafter proceed to
       cause the meeting to be held as provided herein, then the Company
       or the holders of Securities in the amount above specified may
       determine the time and the place in such designated locations for
       such meeting and may call such meeting to take any action
       authorized herein by giving notice thereof as provided in the
       Fiscal Agency Agreement.

                 (c)  To be entitled to vote at any meeting of holders
       of Securities, a person shall be (i) a holder of one or more
       Securities, or (ii) a person appointed by an instrument in
       writing as proxy for a holder or holders of Securities by such
       holder or holders, which proxy need not be a holder of
       Securities. The only persons who shall be entitled to be present
       or to speak at any meeting of holders shall be the persons
       entitled to vote at such meeting and their counsel and any
       representatives of the Fiscal Agent and its counsel and any
       representatives of the Company and its counsel.  The persons
       entitled to vote a majority in principal amount of outstanding
       Securities shall constitute a quorum for the transaction of all
       business specified in subsection (a) hereof.  No business shall
       be transacted in the absence of a quorum unless a quorum is
PAGE


       represented when the meeting is called to order.  In the absence
       of a quorum within 30 minutes of the time appointed for any such
       meeting, the meeting shall, if convened at the request of the
       holders of Securities, be dissolved.  In any other case the
       meeting shall be adjourned for a period of not less than 10 days
       as determined by the chairman of the meeting prior to the
       adjournment of such adjourned meeting.  Notice of the reconvening
       of any adjourned meeting shall be given as provided in the Fiscal
       Agency Agreement.  Subject to the foregoing, at the reconvening
       of any meeting adjourned for a lack of a quorum the persons
       entitled to vote 25% in principal amount of the Securities
       outstanding shall constitute a quorum for the taking of any
       action set forth in the notice of the original meeting.  Notice
       of the reconvening of an adjourned meeting shall state expressly
       the percentage of the aggregate principal amount of the
       Securities that shall constitute a quorum.  At a meeting or an
       adjourned meeting duly reconvened and at which a quorum is
       present as aforesaid, any resolution and all matters (except as
       limited by Section 9 of these Terms and Conditions) shall be
       effectively passed and decided if passed or decided by the
       persons entitled to vote a majority in principal amount of the
       Securities represented and voting at such meeting, provided that
       such amount shall not be less than 25 % in principal amount of
       the Securities outstanding.  Any holder of a Security who has
       executed an instrument in writing appointing a person as his
       proxy shall be deemed to be present for the purposes of
       determining a quorum and be deemed to have voted; provided,
       however, that such holder shall be considered as present or
       voting only with respect to the matters covered by such
       instrument in writing.  Any resolution effectively passed or
       decision taken at any meeting of the holders of Securities duly
       held in accordance with this Section 10 shall be binding on all
       the holders of Securities whether or not present or represented
       at the meeting.

                 (d)  The Fiscal Agent may make such reasonable
       regulations as it may deem advisable for any meeting of holders
       of Securities in regard to proof of the holding of Securities and
       of the appointment of proxies and in regard to the appointment
       and duties of inspectors of votes, the submission and examination
       of proxies, certificates and other evidence of the right to vote,
       and such other matters concerning the conduct of the meeting as
       it shall deem appropriate.  Except as otherwise permitted or
       required by any such regulations, the holding of Bearer
       Securities shall be proved by the production of the Bearer
       Securities or by a certificate executed, as depositary, by, and
       the appointment of any proxy shall be proved by having the
       signature of the person executing the proxy witnessed or
       guaranteed by, in each case, any trust company, bank or banker
       satisfactory to the Fiscal Agent.  Such regulations may provide
       that written instruments appointing proxies, regular on their
       face, may be presumed valid and genuine without the proof
       specified herein or other proof.  The holding of Registered
       Securities shall be proved by the registry books maintained in
PAGE


       accordance with the Fiscal Agency Agreement or by a certificate
       or certificates of the Fiscal Agent in its capacity as the
       Company's agent for the maintenance of such books.

                 (e)  The Fiscal Agent shall, by an instrument in
       writing, appoint a temporary chairperson and a temporary
       secretary of the meeting, unless the meeting shall have been
       called by the Company or by the holders of Securities as provided
       herein and in the Fiscal Agency Agreement, in which case the
       Company or the holders calling the meeting, as the case may be,
       shall in like manner appoint a temporary chairperson and a
       temporary secretary.  A permanent chairperson and a permanent
       secretary of the meeting shall be elected by vote of the holders
       of a majority in principal amount of the Securities represented
       at the meeting and entitled to vote.  At any meeting each holder
       or proxy shall be entitled to one vote for each U.S. $1,000
       principal amount of Securities held or represented by him;
       provided, however, that no vote shall be cast or counted at any
       meeting in respect of the Securities challenged as not
       outstanding and ruled by the chairperson of the meeting to be not
       outstanding.  The chairperson of the meeting shall have no right
       to vote, except as a holder or proxy.  Any meeting of holders of
       Securities duly called at which a quorum is present may be
       adjourned from time to time by vote of the holders (or proxies
       for the holders) of a majority in principal amount of the
       Securities represented at the meeting and entitled to vote; and
       the meeting may be held as so adjourned without further notice.

                 (f)  The vote upon any resolution submitted to any
       meeting of holders of Securities shall be written ballots on
       which shall be subscribed the signatures of the holders of
       Securities or of their representatives by proxy and the serial
       number or numbers of the Securities held or represented by them.
       The permanent chairperson of the meeting shall appoint two
       inspectors of votes who shall count all votes cast at the meeting
       for or against any resolution and who shall make and file with
       the secretary of the meeting their verified written reports in
       triplicate of all votes cast at the meeting.  A record, at least
       in triplicate, of the proceedings of each meeting of holders of
       Securities shall be prepared by the secretary of the meeting and
       there shall be attached to said record the original reports of
       the inspectors of votes on any vote by ballot taken thereat and
       affidavits by one or more persons having knowledge of the facts
       setting forth a copy of the notice of the meeting and showing
       that said notice was published as provided in the Fiscal Agency
       Agreement.  Each copy shall be signed and verified by the
       affidavits of the permanent chairperson and secretary of the
       meeting, and one of such copy of the notice of the meeting and
       showing that said notice was published as provided in the Fiscal
       Agency Agreement.  Each copy shall be signed and verified by the
       affidavits of the permanent chairperson and secretary of the
       meeting, and one of such copy shall be delivered to the Company
       and another to the Fiscal Agent to be preserved by the Fiscal
       Agent, the copy delivered to the Fiscal Agent to have attached
PAGE


       thereto by ballots voted at the meeting.  Any record so signed
       and verified shall be conclusive evidence of the matters therein
       stated.

            11.  Business Days.  Notwithstanding anything herein or in
       the Fiscal Agency Agreement to the contrary, if any payment of
       interest or premium or principal (or Additional Amounts, if any)
       is due on a day that is not a Business Day, payment shall be made
       on the next succeeding Business Day, with the same effect as if
       made on the day such payment was due, and no interest shall
       accrue for the period after such date.  A "Business Day" is
       defined, with respect to any act to be performed pursuant hereto
       or to the Fiscal Agency Agreement, as any day which is not a
       Saturday, Sunday or a day on which banking institutions in the
       place where such act is to occur are authorized or obligated by
       applicable law, regulation or executive order to close.

                 (a)  In acting under the Fiscal Agency Agreement and in
       connection with the Securities, the Fiscal Agent is acting solely
       as agent of the Company and does not assume any obligation, or
       relationship of agency or trust, for or with the owner or holder
       of this Security or any interest coupon appertaining hereto,
       except that funds held by the Fiscal Agent for payment on this
       Security shall be held in trust by it and applied as set forth
       herein, but need not be segregated from other funds held by it,
       except as required by law.  For a description of the duties and
       the immunities and rights of the Fiscal Agent under the Fiscal
       Agency Agreement, reference is made to the Fiscal Agency
       Agreement, and the obligations of the Fiscal Agent to the holder
       hereof are subject to such immunities and rights.

                 (b)  Any monies paid by the Company to any paying
       agency for payment of principal of, premium, if any, or interest
       on any Security (including Additional Amounts, if any, in respect
       thereof) and remaining unclaimed for two years after such payment
       has been made shall be repaid to the Company and to the extent
       permitted by law the holder of any Security shall thereafter look
       only to the Company for any payment thereof as a general
       unsecured obligation thereof and all liability of the Fiscal
       Agent with respect thereto shall cease.

                 (c)  No reference herein to the Fiscal Agency Agreement
       and no provision of this Security or of the Fiscal Agency
       Agreement shall alter or impair the obligation of the Company,
       which is absolute and unconditional, to pay the principal of,

       described above) on this Security at the times, places and rate,
       and in the coin or currency, herein prescribed or to convert or
       redeem (at the request of a holder) this Security as provided

       publication in London or Luxembourg is not practical, in an

       expected that publication in New York City will be made in The
       Wall Street Journal (Eastern edition), in London in the Financial
       Times and in Luxembourg in the Luxemburger Wort.  Notices shall

             THERMO ELECTRON CORPORATION, a corporation duly incorporated
        and existing under the laws of the State of Delaware (the
        "Company"), for value received, hereby promises to pay to bearer
        upon presentation and surrender of this Global Security the
        principal sum of $_______ United States Dollars on January 1,
        2003 and to pay interest thereon, from the date hereof,
        semiannually in arrears on January 1 and July 1 in each year,
        commencing July 1, 1996, at the rate of 4q% per annum, until the
        principal hereof is paid or made available for payment; provided,
        however, that interest on this Global Security shall be payable
        only after the issuance of the definitive Securities for which
        this Global Security is exchangeable and, in the case of
        definitive Securities in bearer form, only upon presentation and
        surrender (at an office or agency outside the United States, its
        territories and its possessions, except as otherwise provided in
        the Fiscal Agency Agreement referred to below) of the interest
        coupons thereto attached as they severally mature.

             This Global Security is one of a duly authorized issue of
        Securities of the Company designated as specified in the title
        hereof, issued and to be issued under the Fiscal Agency Agreement
        dated as of January 3, 1996 (the "Fiscal Agency Agreement")
        between the Company and Chemical Bank, as fiscal agent (the
        "Fiscal Agent", which term includes any successor fiscal agent
        under the Fiscal Agency Agreement).  This Global Security is a
        temporary security and is exchangeable in whole or from time to
        time in part without charge upon request of the holder hereof for
        definitive Securities in bearer form, with interest coupons
        attached, or in registered form, without coupons, of authorized
        denominations, (a) not earlier than the day following expiration
        of the 40-day period that begins on the date hereof and (b) as
        promptly as practicable following presentation of certification,
        in the forms set forth as Exhibits C and F of the Fiscal Agency
        Agreement for such purpose, that the beneficial owner or owners
        of this Global Security (or, if such exchange is only for a part
        of this Global Security, of such part) are not United States
        Persons or other persons who have purchased such Debenture for
        resale to United States Persons.  Definitive Securities in bearer
        form to be delivered in exchange for any part of this Global
        Security shall be delivered only outside of the United States,
        its territories and its possessions.  Upon any exchange of a part
        of this Global Security for definitive Securities, the portion of
        the principal amount hereof so exchanged shall be endorsed by the
        Fiscal Agent or its agents on the Schedule of Exchanges hereto,
        and the principal amount hereof shall be reduced for all purposes
        by the amount so exchanged.
PAGE


             Until exchanged in full for definitive Securities, this
        Global Security shall in all respects be entitled to the same
        benefits under, and subject to the same terms and conditions of,
        the Fiscal Agency Agreement as definitive Securities
        authenticated and delivered thereunder, except that neither the
        holder hereof nor the beneficial owners of this Global Security
        shall be entitled to receive payment of interest hereon, except
        as provided above, or to convert this Global Security into shares
        of Common Stock of the Company or any other security, cash or
        other property.

             THIS GLOBAL SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
        ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS,
        UNITED STATES OF AMERICA, WITHOUT GIVING EFFECT TO ITS CONFLICTS
        OF LAW RULES.

             All terms used in this Global Security which are defined in
        the Fiscal Agency Agreement shall have the meanings assigned to
        them in the Fiscal Agency Agreement.

             Unless the certificate of authentication hereon has been
        manually executed by an authorized signatory of the Fiscal Agent,
        this Global Security shall not be entitled to any benefit under
        the Fiscal Agency Agreement or valid or obligatory for any
        purpose.

             IN WITNESS WHEREOF, the Company has caused this Global
        Security to be duly executed in its corporate name by its duly
        authorized signatory under its corporate seal.

        owned by a United States person (other than a financial

        after such interest payment date.

             We understand that this certification is required in
        connection with certain tax laws and, if applicable, certain
        securities laws of the United States.  In connection therewith,
        if administrative or legal proceedings are commenced or

        Ladies and Gentlemen:

             We are delivering this letter in connection with the
        purchase of 4 1/4% Convertible Subordinated Debentures due 2003 (the
        _Debentures_) of Thermo Electron Corporation, a Delaware
        corporation (the _Company_), which are convertible into shares of
        Common Stock of the Company (the _Underlying Shares_ and together
        with the Debentures, the "Restricted Securities"), all as
        described in the Company's Offering Circular dated November 28,
        1995 (the "Offering Circular").

             We represent, warrant and agree as follows:

                  1.   We understand and hereby acknowledge that the
        Debentures and, prior to the effectiveness of a registration
        statement filed with the Securities and Exchange Commission
        relating to the resale of the Underlying Shares, the Underlying
        Shares have not been registered under the Securities Act of 1933,
        as amended (the "Securities Act"), and may not be sold except as
        permitted in the following sentence.  We agree on our own behalf
        and on behalf of any investor account (as hereinafter defined)
        for which we are purchasing the Debentures to offer, sell or
        otherwise transfer such Restricted Securities prior to the date
        which is three years (or the then applicable holding period under
        Rule 144(k) under the Securities Act (or successor provision))
        after the later of the date of original issue and the last date
        on which the Company or any affiliate of the Company was the
        owner of such Restricted Securities (or any predecessor thereto)
        (the "Resale Restriction Termination Date") only (a) to the
        Company, (b) pursuant to a registration statement which has been
        declared effective under the Securities Act, (c) for so long as
        the Debentures are eligible for resale pursuant to Rule 144A
        under the Securities Act, to a person we reasonably believe is a
        qualified institutional buyer under Rule 144A (a _QIB_) that
        purchases for its own account or for the account of a QIB to whom
PAGE


        notice is given that the transfer is being made in reliance on
        Rule 144A (d) outside the United States in a transaction meeting
        the requirements of Rule 904 of Regulation S under the Securities
        Act, (e) in a transaction arranged by a broker or dealer
        registered under the Securities Exchange Act of 1934, as amended,
        to an institutional "accredited investor" within the meaning of
        subparagraph (a)(1), (2), (3), or (7) of Rule 501 under the
        Securities Act (an "Institutional Accredited Investor") that is
        purchasing Restricted Securities for its own account or for the
        account of such Institutional Accredited Investor, for investment
        purposes and not with a view to, or for offer or sale in
        connection with, any distribution in violation of the Securities
        Act or (f) pursuant to any other available exemption from the
        registration requirements of the Securities Act as confirmed in
        an opinion of counsel, acceptable in from and substance to the
        Company, and, in each case, in accordance with the applicable
        securities laws of any state of the United States or any other
        applicable jurisdiction and subject to any requirement of law
        that the disposition of our property or the property of such
        investor account or accounts be at all times within our or their
        control and in compliance with any applicable state securities
        laws.  The foregoing restrictions on resale will not apply
        subsequent to the Resale Restriction Termination Date.  If any
        resale or other transfer of the Restricted Securities is proposed
        to be made pursuant to clause (e) above prior to the Resale
        Restriction Termination Date, the transferor shall deliver a
        letter from the transferee containing representations and
        agreements substantially the same as those contained herein.  We
        acknowledge that the Company and the Fiscal Agent reserve the
        right prior to any offer, sale or other transfer prior to the
        Resale Restriction Termination Date of the Debentures and Common
        Stock pursuant to clause (d), (e) or (f) above to require the
        delivery of an opinion of counsel, certifications or other
        information acceptable to the Company and the Fiscal Agent in
        form and substance.

                  2.   We are an Institutional Accredited Investor within
        the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501
        under the Securities Act.

                  3.   Any purchase of Restricted Securities by us will
        be for our own account or for the account of one or more other
        Institutional Accredited Investors (an "investor account") as to
        which we exercise sole investment discretion.

                  4.   We are not acquiring the Restricted Securities
        with a view to, or for offer or sale in connection with, any
        distribution in violation of the Securities Act.

                  5.   We have such knowledge and experience in financial
        and business matters as to be capable of evaluating the merits
        and risks of purchasing the Restricted Securities, and we and any
        investor account for which we are acting are each able to bear
        the economic risk of our or its investment.

                  6.   We have received a copy of the Offering Circular
        and acknowledge that we have had access to such financial and
        other information, and have been afforded the opportunity to ask
        such questions of representatives of the Company and receive
PAGE


        answers thereto, as we deem necessary in connection with our
        decision to purchase Restricted Securities.

             We understand that the registrar and transfer agent will not
        be required to accept for registration of transfer any Restricted
        Securities, except upon presentation of evidence satisfactory to
        the Company and the Fiscal Agent that the foregoing restrictions
        on transfer have been complied with.  We further understand that
        the Restricted Securities will be in the form of definitive
        physical certificates and that such certificates will bear a
        legend reflecting the substance of paragraph 1 above.

             We shall provide to any person purchasing any Restricted
        Securities from us a notice advising such purchaser that
        transfers of the Debentures and the Underlying Shares are
        restricted as set forth herein.

             We understand that prior to any proposed offer of Debentures
        occurring before the Resale Restriction Termination Date, we must
        check the appropriate box set forth on the reverse of the
        certificate evidencing such Debentures relating to the manner of
        such transfer and submit the certificates to the Fiscal Agent.
        In addition, we understand that prior to any proposed transfer of
        Debentures or any proposed offer of Underlying Shares acquired
        upon conversion of Debentures when there is not effective
        registration statement covering such Underlying Shares to an
        institutional accredited investor occurring before the Resale
        Restriction Termination Date, we may be required to furnish to
        the Company and the Fiscal Agent such certifications, legal
        opinion or other information as they may reasonably require to
        confirm that the proposed transfer is being made pursuant to an
        exemption from, or in a transaction not subject to, the
        registration requirements of the Securities Act, and that
        transfers occurring before the Resale Restriction Termination
        Date to any other person pursuant to another available exemption
        under the Securities act will require an opinion of counsel
        satisfactory to the Company.

             We acknowledge that you and others will rely upon our
        confirmations, acknowledgments and agreements set forth herein,
        and we agree to notify you promptly in writing of any of our
        representations or warranties herein ceases to be accurate and
        complete. You are irrevocably authorized to produce this letter
        or a copy hereof to any interested party in any administrative or
        legal proceeding or official inquiry with respect to the matters
        covered hereby.

             THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN
        ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS.

                                      Very truly yours,
