                 agents with respect to the Debentures of such series;

                       (15)  the currency or currencies, including
                 composite currencies, in which the Debentures of the

                                  -11-




                 a condition to the issuance of the Debentures of such
                 series in definitive form (whether upon original issue
                 or upon exchange of a temporary Debenture of such
                 series), the form and terms of such certificates,
                 documents or conditions;

                       (21)  any other affirmative or negative covenants
                 with respect to the Debentures of such series;

                       (22)  whether the Debentures of such series shall
                 be issued in whole or in part in the form of one or
                 more Global Debentures and in such case (i) the
                 Depositary for such Global Debenture or Debentures,
                 which Depositary must be a clearing agency registered
                 under the Securities Exchange Act, (ii) the
                 circumstances under which any such Global Debenture may
                 be exchanged for Debentures registered in the name of,
                 and under which any transfer of such Global Debenture
                 may be registered in the name of, any Person other than
                 such Depositary or its nominee, if other than as set
                 forth in Section 2.13 and (iii) any other provisions
                 regarding such Global Debentures which provisions may
                 be in addition to or in lieu of, in whole or in part,
                 the provisions of Section 2.13; and

                       (23)  any other terms of a particular series and
                 any other provisions expressing or referring to the
                 terms and conditions upon which the Debentures of such
                 series are to be issued under the Indenture, which
                 terms and provisions are not in conflict with the
                 provisions of this Indenture; provided, however, that
                 the addition to or subtraction from or variation of
                 Articles IV, V, VI, VII, and X (and Section 1.1,
                 insofar as it relates to the definition of certain
                 terms as used in such Articles) with regard to the
                 Debentures of a particular series shall not be deemed
                 to constitute a conflict with the provisions of those
                 Articles.

                 All Debentures of any one series shall be substantially
            identical except as to denomination and except as may
            otherwise be provided in or pursuant to such resolution of
            the Board of Directors or in any such indenture supplemental
            hereto.  Not all Debentures of any one series need be issued
            at the same time, and, unless otherwise so provided, a
            series may be reopened for issuances of additional
            Debentures of such series.

                 If any of the terms of the Debentures of a series are
            established by action taken pursuant to a resolution of the
            Board of Directors, a copy of any appropriate record of such
            action shall be certified by the Secretary or an Assistant
            Secretary of the Company and delivered to the Trustee with
            an Officers' Certificate setting forth the terms of the
            Debentures of such series. With respect to Debentures of a
            series which are not to be issued at one time, such
            resolution of the Board of Directors or action may provide
            general terms or parameters for Debentures of such series
            and provide either that the specific terms of

                                  -12-




            particular Debentures of such series shall be specified in a
            Company Order or that such terms shall be determined by the
            Company or its agents in accordance with a Company Order as
            contemplated by the proviso clause of Section 2.5.

                 SECTION 2.3.      Denominations.  The Debentures of
            each series shall be registered Debentures without coupons,
            in such denominations as shall be specified as contemplated
            by Section 2.2.  In the absence of any such provisions with
            respect to the Debentures of any series, the Debentures of
            such series shall be issuable in denominations of $1,000 or
            of any integral multiple of $1,000.

                 SECTION 2.4.      Execution of Debentures;
            Authentication.  The Debentures shall be executed on behalf
            of the Company by its President or one of its Vice Chairmen
            or Vice Presidents, whose signatures may be manual or
            facsimile, and its corporate seal shall be thereunto affixed
            (or a facsimile thereof shall be engraved, printed, or
            otherwise reproduced thereon) and attested by the manual or
            facsimile signature of its Secretary or one of its Assistant
            Secretaries.  In case any officer of the Company who shall
            have signed any of the Debentures shall cease to be such
            officer before the Debentures so signed and attested shall
            actually have been authenticated and delivered by the
            Trustee or the Authenticating Agent or disposed of by the
            Company, such Debentures nevertheless may be authenticated,
            issued and delivered or disposed of with the same force and
            effect as though the person or persons who signed or
            attested such Debentures had not ceased to be such officer
            of the Company; and any such Debenture may be signed and
            attested on behalf of the Company by such persons, as at the
            actual date of the execution of such Debenture, shall be the
            proper officers of the Company, although at the date of such
            Debenture or the date of execution of this Indenture any
            such person was not such officer.

                 No Debenture of any series shall be entitled to the
            benefits hereof or shall be or become valid or obligatory
            for any purpose unless there shall appear on the Debenture a
            certificate of authentication, substantially in the form
            hereinbefore recited, manually executed by the Trustee for
            such series or an Authenticating Agent; and such certificate
            on any Debenture issued by the Company shall be conclusive
            evidence that it has been duly authenticated and delivered
            hereunder.

                 Notwithstanding the foregoing, if any Debenture shall
            have been duly authenticated and delivered hereunder but
            never issued and sold by the Company, and the Company shall
            deliver such Debenture to the Trustee for cancellation as
            provided in Section 2.11 together with a written statement
            (which need not be accompanied by an Opinion of Counsel)
            stating that such Debenture has not been issued and sold by
            the Company, for all purposes of this Indenture such
            Debenture shall be deemed not to have been authenticated and
            delivered hereunder and shall not be entitled

                                  -13-




            to the benefits of this Indenture.

                 If the form or forms or terms of the Debentures of any
            series have been established in or pursuant to one or more
            resolutions of the Board of Directors or indentures
            supplemental hereto as permitted by Sections 2.1 and 2.2, in
            authenticating such Debentures, and accepting the additional
            responsibilities under this Indenture in relation to such
            Debentures, the Trustee and the Authenticating Agent shall
            be entitled to receive, and (subject to Section 11.2) shall
            be fully protected in relying upon, a copy of such
            resolution or resolutions delivered to the Trustee and the
            Authenticating Agent and certified by the Secretary or
            Assistant Secretary of the Company to have been duly adopted
            by the Board of Directors and to be in full force and effect
            on the date of such certification, and an Opinion of Counsel
            stating:

                       (1)   if the form or forms of such Debentures
                 have been established by or pursuant to a resolution of
                 the Board of Directors or indenture supplemental
                 hereto, that such form or forms have been established
                 in conformity with the provisions of this Indenture;

                       (2)   if the terms of such Debentures have been
                 established by or pursuant to a resolution of the Board
                 of Directors or indenture supplemental hereto, that
                 such terms have been established in conformity with the
                 provisions of this Indenture; and

                       (3)   that such Debentures, when authenticated
                 and delivered by the Trustee or an Authenticating Agent
                 and issued by the Company in the manner and subject to
                 any conditions specified in such Opinion of Counsel,
                 will constitute valid and legally binding obligations
                 of the Company, enforceable in accordance with their
                 terms, subject to bankruptcy, insolvency, fraudulent
                 conveyance, reorganization and other laws of general
                 applicability relating to or affecting the enforcement
                 of creditors' rights and to general equity principles
                 (or such other similar matters as in the opinion of
                 such counsel shall not materially adversely affect such
                 enforceability).

            provided, however, that, with respect to Debentures of a
            series which are not to be issued at one time, the Trustee
            and the Authenticating Agent shall be entitled to receive
            such Opinion of Counsel only once at or prior to the time of
            the first authentication of Debentures of such series and
            that the opinions described in clauses (2) and (3) above may
            state, respectively:

                                  -14-




                       (a)   that, when the terms of such Debentures
                 shall have been established pursuant to a Company Order
                 or pursuant to such procedures as may be specified from
                 time to time by a Company Order, all as contemplated by
                 and in accordance with a resolution of the Board of
                 Directors or an Officers' Certificate pursuant to a
                 resolution of the Board of Directors or indenture
                 supplemental hereto, as the case may be, such terms
                 will have been established in conformity with the
                 provisions of this Indenture; and

                       (b)   that such Debentures, when (i) executed by
                 the Company, (ii) completed, authenticated and
                 delivered by the Trustee or the Authenticating Agent in
                 accordance with this Indenture, (iii) issued and
                 delivered by the Company, and (iv) paid for, all as
                 contemplated by and in accordance with the aforesaid
                 Company Order or specified procedures, as the case may
                 be, will constitute valid and legally binding
                 obligations of the Company, enforceable in accordance
                 with their terms, subject to bankruptcy, insolvency,
                 fraudulent conveyance, reorganization and other laws of
                 general applicability relating to or affecting the
                 enforcement of creditors' rights and to general
                 equitable principles (or such other similar matters as
                 in the opinion of such counsel shall not materially
                 adversely affect such enforceability).

                 Notwithstanding the provisions of Sections 2.1, 2.2,
            14.8 and this Section, if all the Debentures of a series are
            not to be originally issued at one time, the resolution of
            the Board of Directors or indenture supplemental hereto, the
            certified copy of the record of action taken pursuant to
            such resolution or supplemental indenture, the Officers'
            Certificate, the Company Order and any other documents
            otherwise required pursuant to such Sections need not be
            delivered at or prior to the time of authentication of each
            Debenture of such series if such documents are delivered at
            or prior to the authentication upon original issuance of the
            first Debenture of such series to be issued; provided,
            however, that any subsequent request by the Company to the
            Trustee or the Authenticating Agent to authenticate
            Debentures of such series shall constitute a representation
            and warranty by the Company that, as of the date of such
            request, the statements made in the Officers' Certificate
            delivered pursuant to Section 14.8 at or prior to
            authentication of the first such Debenture shall be true and
            correct on the date thereof as if made on and as of the date
            hereof.

                 The Trustee or the Authenticating Agent shall not be
            required to authenticate such Debentures if the issue of
            such Debentures pursuant to this Indenture will adversely
            affect the Trustee's or the Authenticating Agent's own
            rights, duties or immunities under the Debentures and this
            Indenture or otherwise in a manner which is not reasonably
            acceptable to the Trustee or the Authenticating Agent.


                                  -15-



                 With respect to Debentures of a series which are not
            all issued at one time, the Trustee and the Authenticating
            Agent may conclusively rely, as to the authorization by the
            Company of any such Debentures, the form and terms thereof
            and the legality, validity, binding effect and
            enforceability thereof, upon the Opinion of Counsel,
            Officers' Certificate and other documents delivered pursuant
            to Sections 2.1, 2.2, 14.8 and this Section, as applicable,
            at or prior to the time of the first authentication of
            Debentures of such series unless and until such opinion,
            certificate or other documents have been superseded or
            revoked in a writing delivered to the Trustee.  In
            connection with the authentication and delivery of
            Debentures of a series which are not all issued at one time,
            the Trustee and the Authenticating Agent shall be entitled
            to assume that the Company's instructions to authenticate
            and deliver such Debentures do not violate any rules,
            regulations or orders of any governmental agency or
            commission having jurisdiction over the Company.

                 SECTION 2.5.      Issue of Debentures.  The Trustee and
            the Authenticating Agent, forthwith upon the execution and
            delivery of this Indenture and from time to time thereafter,
            upon the execution and delivery to it of Debentures of any
            series by the Company as herein provided, and without
            further action on the part of the Company, shall
            authenticate such Debentures up to a maximum amount, if any,
            designated for such series pursuant to Section 2.2 and
            deliver them to or upon the receipt of a Company Order;
            provided, however, that if not all the Debentures of a
            series are to be issued at one time and if the resolution of
            the Board of Directors or indenture supplemental hereto
            establishing such series as contemplated by Sections 2.1 and
            2.2 shall so permit, such Company Order may set forth
            procedures acceptable to the Trustee for the issuance of
            such Debentures and for determining the form or forms or
            terms of particular Debentures of such series including, but
            not limited to, interest rate, if any, maturity date, date
            of issuance and date from which interest, if any, shall
            accrue.

                 SECTION 2.6.      Transfer of Debentures.  The transfer
            of any Debenture of any series may be registered by the
            registered owner thereof, in person or by his attorney duly
            authorized in writing, at the office or agency of the
            Company to be maintained by it as provided in Section 4.2,
            by delivering such Debenture for cancellation, accompanied
            by delivery of a duly executed instrument of transfer, in a
            form approved by the Company and satisfactory to the
            Trustee, and thereupon the Company shall execute in the name
            of the transferee or transferees, and the Trustee or the
            Authenticating Agent shall authenticate and deliver, a new
            Debenture or Debentures of the same series and of like form
            for the same aggregate principal amount.


                                  -16-




                 SECTION 2.7.      Persons deemed owners of Debentures.
            Prior to due presentation of any Debenture for registration
            of transfer, the person in whose name a Debenture of any
            series shall be registered, on books kept for such purpose
            in accordance with Section 4.2, shall be deemed the absolute
            owner thereof for all purposes of this Indenture, whether or
            not such Debenture is overdue, and neither the Company, the
            Trustee nor any Paying Agent or conversion agent nor any
            Debenture registrar shall be affected by notice to the
            contrary. Subject to the provisions of Section 2.12, payment
            of or on account of the principal, premium, if any, and
            interest shall be made only to or upon the order in writing
            of such registered owner thereof, but such registration may
            be changed as above provided.  All such payments shall be
            valid and effectual to satisfy and discharge the liability
            upon such Debenture to the extent of the sum or sums so
            paid.

                 SECTION 2.8.      Provisions for Debentures in
            temporary form.  Until Debentures of any series in
            definitive form are ready for delivery, the Company may
            execute and, upon its request in writing, the Trustee or the
            Authenticating Agent shall authenticate and deliver, in lieu
            thereof and subject to the same conditions, one or more
            printed or lithographed Debentures in temporary form,
            substantially of the tenor of Debentures of the same series,
            without a recital of specific redemption prices and with
            such other appropriate omissions, variations and insertions,
            all as may be determined by the Board of Directors. Until
            exchanged for Debentures of the same series in definitive
            form such Debentures in temporary form shall be entitled to
            the benefits of this Indenture.  The Company shall, without
            unreasonable delay after the issue of Debentures in
            temporary form, prepare, execute and deliver definitive
            Debentures of the same series to the Trustee, and upon the
            presentation and surrender of Debentures in temporary form,
            the Trustee or the Authenticating Agent shall authenticate
            and deliver, in exchange therefor, Debentures of the same
            series in definitive form for the same aggregate principal
            amount as the Debentures in temporary form surrendered.
            Such exchange shall be made by the Company at its own
            expense and without any charge therefor.

                 SECTION 2.9.      Mutilated, destroyed, lost or stolen
            Debentures.  Upon receipt by the Company, the Trustee and
            the Authenticating Agent of evidence satisfactory to them
            that any Debenture of any series has been mutilated,
            destroyed, lost or stolen, and upon receipt of indemnity
            (and in case of a destroyed, lost or stolen Debenture, proof
            of ownership) satisfactory to them, the Company shall, in
            the case of a mutilated Debenture, and may in the case of a
            lost, stolen or destroyed Debenture, execute, and thereupon
            the Trustee or the Authenticating Agent shall authenticate
            and deliver, a new Debenture of the same series of like
            tenor bearing a serial number not contemporaneously
            outstanding (bearing such notation, if any, as may be
            required by the rules of any stock exchange upon which the
            Debentures of the same series are listed or are to

                                  -17-




            be listed), in exchange and substitution for, and upon
            surrender and cancellation of, the mutilated Debenture, or
            in lieu of and in substitution for the Debenture so
            destroyed, lost or stolen; or, if any mutilated, destroyed,
            lost or stolen Debenture of any series shall have matured or
            be about to mature, instead of issuing a new Debenture, the
            Company, upon written notice to the Trustee or the
            Authenticating Agent, may pay the same without surrender of
            the destroyed, lost or stolen Debenture.  The Company may
            require payment of the expenses which may be incurred by the
            Company or any agent thereof and the charges and expenses of
            the Trustee and the Authenticating Agent in the premises.
            Any Debenture issued under the provisions of this Section
            2.9 in lieu of any Debenture alleged to have been destroyed,
            lost or stolen, shall constitute an additional contractual
            obligation of the Company, whether or not the Debenture
            alleged to have been destroyed, lost or stolen shall be
            found at any time, and shall be equally and proportionately
            entitled to the benefits of this Indenture with all other
            Debentures of the same series issued under this Indenture.

                 All Debentures shall be held and owned upon the express
            condition that the foregoing provisions are exclusive with
            respect to the replacement or payment of mutilated,
            destroyed, lost or stolen Debentures, and shall preclude, to
            the extent lawful, any and all other rights or remedies,
            notwithstanding any law or statute existing or hereafter
            enacted to the contrary with respect to the replacement or
            payment of negotiable instruments or other securities
            without their surrender.

                 SECTION 2.10.  Exchanges of Debentures.  Debentures of
            any series may, upon surrender thereof as hereinafter
            provided in this Section 2.10, be exchanged for one or more
            Debentures of the same series of the same aggregate
            principal amount, in authorized denominations.  The
            Debentures to be exchanged shall be surrendered at the
            office or agency of the Company to be maintained by it as
            provided in Section 4.2, accompanied by duly executed
            instruments of transfer in a form acceptable to the Company
            and the Trustee, and the Company shall execute and the
            Trustee or the Authenticating Agent shall authenticate and
            deliver, in exchange therefor, the Debenture or Debentures
            of the same series, bearing numbers not contemporaneously
            outstanding, which the Debentureholder making the exchange
            shall be entitled to receive.  Every exchange of Debentures
            of any series shall be effected in such manner as may be
            prescribed by the Company with the approval of the Trustee,
            and as may be necessary to comply with the regulations of
            any stock exchange upon which Debentures of such series are
            listed or are to be listed or to conform to usage in respect
            thereof.

                 Upon every exchange or registration of transfer of
            Debentures, no service charge shall be made but the Company
            may require the payment of any taxes or other governmental
            charges required to be paid with respect to such exchange or

                                  -18-



            registration, as a condition precedent to the exercise of
            the privilege of such exchange or registration.

                 All Debentures executed, authenticated and delivered in
            exchange or upon registration of transfer shall be the valid
            obligations of the Company, evidencing the same debt as the
            Debentures surrendered, and shall be entitled to the
            benefits of this Indenture to the same extent as the
            Debentures in exchange for which they were authenticated and
            delivered.

                 The Company shall not be required to make exchanges or
            registrations of transfer under any provision of this
            Article II of: (a) the Debentures of any series for the
            period of 15 days next preceding the date of any designation
            of Debentures of such series to be redeemed, as provided in
            Article V, or (b) any Debenture or portion thereof called or
            to be called for redemption.

                 SECTION 2.11.     Cancellation of Surrendered
            Debentures.  All Debentures of any series surrendered for
            the purpose of payment, exchange, conversion or cancellation
            (including Debentures authenticated which the Company has
            not issued and sold) shall, if surrendered to the Company
            or any Paying Agent or conversion agent, be delivered to the
            Trustee and cancelled by it, or, if surrendered to the
            Trustee, shall be cancelled by it, and no Debentures shall
            be issued in lieu thereof except as expressly permitted by
            any of the provisions of this Indenture or as otherwise
            provided in the resolution of the Board of Directors or
            indenture supplemental hereto establishing such series as
            contemplated by Section 2.2.  All Debentures of any series
            surrendered for the purpose of redemption or credit against
            any sinking fund shall similarly be delivered to the Trustee
            for cancellation, and no Debentures shall be issued in lieu
            thereof except Debentures of the same series in the case of
            redemption of a Debenture in part only.  If the Company
            shall acquire any of the Debentures, such acquisition shall
            not operate as a redemption or satisfaction of the
            indebtedness represented by such Debentures unless and until
            the same are delivered to the Trustee for cancellation.
            Unless otherwise directed in writing by the Company, the
            Trustee shall destroy all cancelled Debentures and furnish
            to the Company a certificate evidencing such destruction.

                 SECTION 2.12.     Payment of interest; Defaulted
            interest.  Except as provided in Section 13.4, interest
            (except defaulted interest) on the Debentures of any series
            which is payable on any interest payment date shall be paid
            to the persons who are Debentureholders of such series at
            the close of business on the record date specified for that
            purpose as contemplated by Section 2.2.  At the option of
            the Company, payment of interest on any Debenture may be
            made by check mailed to the holder's registered address.

                                  -19-



                 If the Company defaults in a payment of interest on the
            Debentures of any series, it shall pay the defaulted
            interest to the persons who are Debentureholders of such
            series at the close of business on a subsequent special
            record date.  The Company shall fix the record date (which
            shall be not less than five Business days prior to the date
            of payment of such defaulted interest) and payment date.  At
            least 15 days before the record date, the Company shall mail
            to each Debentureholder of such series a notice that states
            the record date, the payment date and the amount of
            defaulted interest to be paid.  The Company shall notify the
            Trustee in writing of the amount of defaulted interest
            proposed to be paid on each Debenture of such series and the
            date of the proposed payment, and at the same time the
            Company shall deposit with the Trustee or any paying agent
            for such series an amount of money in immediately available
            funds by 10:00 a.m. New York time on the payment date equal
            to the aggregate amount proposed to be paid in respect of
            such defaulted interest or shall make arrangements
            satisfactory to any Paying Agent for such series for such
            deposit prior to the date of the proposed payment.  The
            Company may pay defaulted interest in any other lawful
            manner not inconsistent with the requirements of any
            securities exchange on which the Debenture may be listed,
            and upon notice as may be required by such exchange if,
            after notice given by the Company to the Trustee of the
            proposed payment pursuant to this clause, such payment shall
            be deemed practicable by the Trustee.

                 SECTION 2.13.     Global Debentures; Depositary.  For
            the purposes of this Section, the term "Agent Member" means
            a member of, or participant in, a Depositary; the term
            "Depositary" means, with respect to Debentures issuable or
            issued in whole or in part in the form of one or more Global
            Debentures, the entity designated as Depositary by the
            Company pursuant to Section 2.2, and, if at any time there
            is more than one such person, "Depositary" as used with
            respect to the Debentures shall mean the respective
            Depositary with respect to particular series of Debentures;
            and the term "Global Debenture" means a global certificate
            evidencing all or part of the series of Debentures as shall
            be specified herein, issued to the Depositary for the series
            or such portion of the series, and registered in the name of
            such Depositary or its nominee.  The Global Debenture may
            provide that it shall represent the aggregate amount of
            Outstanding Debentures from time to time endorsed thereon
            which may from time to time be reduced to reflect exchanges.
            Any endorsement to reflect the amount, or any increase or
            decrease in the amount, of Outstanding Debentures shall be
            made by the Trustee.

                 Notwithstanding Section 2.10, except as otherwise
            specified as contemplated by Section 2.2., hereof, any
            Global Debenture shall be exchangeable only as provided in
            this paragraph.  A Global Debenture shall be exchangeable
            pursuant to this Section 2.13 if (i) the Depositary notifies
            the Company that it is

                                  -20-




            unwilling or unable to continue as Depositary for such
            Global Debenture or if at any time the Depositary ceases to
            be a clearing agency registered under the Securities
            Exchange Act, (ii) the Company in its sole discretion
            determines that all Global Debentures of any series then
            outstanding under the Indenture shall be exchangeable for
            definitive Debentures of such series in registered form or
            (iii) an Event of Default with respect to the Debentures of
            the series represented by such Global Debenture has occurred
            and is continuing.  Any Global Debenture of such series
            exchangeable pursuant to the preceding sentence shall be
            exchangeable for definitive Debentures of such series in
            registered form, bearing interest (if any) at the same rate
            or pursuant to the same formula, having the same date of
            issuance, redemption, conversion (if any) and other
            provisions, and of differing denominations aggregating a
            like amount.  Such definitive Debentures of such series
            shall be registered in the names of the owners of the
            beneficial interests in such Global Debentures of such
            series as such names are from time to time provided by the
            relevant participants in the Depositary holding such Global
            Debentures (as such participants are identified from time to
            time by such Depositary).

                 No Global Debenture may be transferred except as a
            whole by a nominee of the Depositary to the Depositary or
            another nominee of the Depositary or by the Depositary or
            any such nominee or a successor of the Depositary or a
            nominee of such successor.  Except as provided above, owners
            solely of beneficial interests in a Global Debenture shall
            not be entitled to receive physical delivery of Debentures
            of such series in definitive form and will not be considered
            the Debentureholders thereof for any purpose under this
            Indenture.

                 Any Global Debenture that is exchangeable pursuant to
            the preceding paragraph shall be exchangeable for Debentures
            of such series in authorized denominations and registered in
            such names as the Depositary that is the Debentureholder of
            such Global Debentures of such series shall direct.

                 In the event that a Global Debenture is surrendered for
            redemption in part pursuant to Section 5.2 or 5.5, the
            Company shall execute, and the Trustee or the Authenticating
            Agent shall authenticate and delivery to the Depositary for
            such Global Debenture, without service charge, a new Global
            Debenture in a denomination and tenor equal to and in
            exchange for the unredeemed portion of the principal for the
            Global Debenture so surrendered.

                 The Agent Members shall have no rights under this
            Indenture with respect to any Global Debenture held on their
            behalf by a Depositary, and such Depositary may be treated
            by the Company, the Trustee, and any agent of the Company or
            the Trustee as the owner of such Global Debenture for all
            purposes whatsoever. Notwithstanding the foregoing, nothing
            herein shall prevent the

                                  -21-




            Company, the Trustee, or any agent of the Company or the
            Trustee, from giving effect to any written certification,
            proxy or other authorization furnished by a Depositary or
            impair, as between a Depositary and its Agent Members, the
            operation of customary practices governing the exercise of
            the rights of a holder of a Debenture of any series,
            including without limitation the granting of proxies or
            other authorization of participants to give or take any
            request, demand, authorization, direction, notice, consent,
            waiver or other action which a Debentureholder is entitled
            to give or take under the Indenture.

                 The Trustee shall not be required to authenticate
            Global Debentures until it has received documentation
            satisfactory to it.

                              ARTICLE III

                      SUBORDINATION OF DEBENTURES

                 SECTION 3.1.      Debentures subordinated to Senior
            Indebtedness.  The Company covenants and agrees, and each
            holder of Debentures by his acceptance thereof, whether upon
            original issue or upon registration of transfer or
            assignment, likewise covenants and agrees, that the payment
            of the principal of, premium, if any, and interest on each
            and all of the Debentures is hereby expressly subordinated,
            to the extent and in the manner hereinafter set forth, in

            Debentures on dissolution, etc.  Upon any payment or

            reorganization of the Company, whether voluntary or
            involuntary, in bankruptcy, insolvency or receivership, or
            upon an assignment for the benefit of creditors or any other
            marshalling of the assets and liabilities of the Company or
            otherwise,

                       (a)   all principal of, premium, if any, and
                 interest then due upon all Senior Indebtedness shall
                 first be paid in full, or payment thereof provided for
                 in money or money's worth, before the holders of the
                 Debentures or the Trustee on their behalf shall be
                 entitled to receive any assets (other than shares of
                 stock of the Company as reorganized or readjusted, or
                 securities of the Company or any other corporation
                 provided for by a plan of reorganization or
                 readjustment, junior to, or the payment of which is
                 subordinated at least to the extent provided in this
                 Article III to the payment of all Senior Indebtedness
                 which may at the time be outstanding or to any
                 securities issued in respect thereof under any such
                 plan of reorganization or readjustment) in respect of
                 the Debentures (for principal, premium, if any, or
                 interest) or of this Indenture;

                                  -22-



                       (b)   any payment or distribution of assets of
                 the Company of any kind or character, whether in cash,
                 property or securities (other than shares of stock of
                 the Company as reorganized or readjusted, or securities
                 of the Company or any other corporation provided for by
                 a plan of reorganization of readjustment, junior to, or
                 the payment of which is subordinated at least to the
                 extent provided in this Article III to the payment of,
                 all Senior Indebtedness which may at the time be
                 outstanding or to any securities issued in respect
                 thereof under any such plan of reorganization or
                 readjustment), to which the holders of the Debentures
                 or the Trustee on their behalf would be entitled,
                 except for the provisions of this Article III, shall be
                 made by the Company or by any receiver, trustee in
                 bankruptcy, liquidating trustee, agent or other person
                 making such payment or distribution, directly to the
                 holders of Senior Indebtedness or their representatives
                 to the extent necessary to pay all Senior Indebtedness
                 in full after giving effect to any concurrent payment
                 or distribution to or for the holders of Senior
                 Indebtedness; and

                       (c)   in the event that, notwithstanding the
                 foregoing, the Trustee or the holder of any Debenture
                 shall have received any payment or distribution of
                 assets of the Company of any kind or character, whether
                 in cash, property or securities (other than shares of
                 stock of the Company as reorganized or readjusted, or
                 securities of the Company or any other corporation
                 provided for by a plan of reorganization or
                 readjustment, junior to, or the payment of which is
                 subordinated at least to the extent provided in this
                 Article III to the payment of, all Senior Indebtedness
                 which may at the time be outstanding or to any
                 securities issued in respect thereof under any such
                 plan of reorganization or readjustment), before all
                 Senior Indebtedness is paid in full and if such fact
                 shall have been made known to the Trustee or such
                 Debentureholder, then and in such event such payment or
                 distribution of assets of the Company shall be paid
                 over or delivered forthwith to the receiver, trustee in
                 bankruptcy, liquidating trustee, agent or other person
                 making payment or distribution of assets of the Company
                 for application to the payment of all Senior
                 Indebtedness remaining unpaid to the extent necessary
                 to pay all Senior Indebtedness in full, in money or
                 money's worth, after giving effect to any concurrent
                 payment or distribution to or for the holders of Senior
                 Indebtedness.

                 The consolidation or merger of the Company with or into
            another corporation, or any consolidation or merger of any
            other corporation with or into the Company, or the
            liquidation or dissolution of the Company following the
            sale, transfer or lease of substantially all of the property
            and assets of the Company to another corporation shall not
            be deemed a dissolution, winding-up

                                  -23-




            or total or partial liquidation or reorganization of the
            Company or an assignment or other marshalling of the assets
            and liabilities of the Company for purposes of this Section
            3.2 so long as such other corporation shall, as a part of
            any such consolidation, merger, sale, conveyance or lease
            comply with the conditions stated in Article X.

                 Subject to the payment in full, in money or money's
            worth, of all Senior Indebtedness, the rights of the holders
            of the Debentures shall be subrogated to the rights of the
            holders of Senior Indebtedness to receive payments or
            distributions of assets of the Company applicable to Senior
            Indebtedness until the Debentures shall be paid in full, and
            no such payments or distributions to the Debentureholders of
            cash, properties or securities otherwise distributable to
            holders of Senior Indebtedness shall, as between the
            Company, its creditors, other than the holders of Senior
            Indebtedness, and the holders of the Debentures, be deemed
            to be a payment by the Company to or on account of the
            Debentures, it being understood that the provisions of this
            Article III are and are intended solely for the purpose of
            defining the relative rights of the holders of the
            Debentures, on the one hand, and the holders of Senior
            Indebtedness, on the other hand.  Nothing contained in this
            Article III or elsewhere in this Indenture or in the
            Debentures is intended to or shall alter or impair, as
            between the Company and the holders of Debentures, the
            obligation of the Company, which is unconditional and
            absolute, to pay to the holders of the Debentures the
            principal of, premium, if any, and interest on the
            Debentures as and when the same shall become due and payable
            in accordance with their terms, or is intended to or shall
            affect (except to the extent specifically provided by this
            paragraph) the relative rights of the holders of the
            Debentures and creditors of the Company, other than the
            holders of Senior Indebtedness, nor shall anything herein or
            therein prevent the Trustee or the holder of any Debenture
            from exercising all remedies otherwise permitted by
            applicable law upon an Event of Default under this
            Indenture, subject to the rights, if any, under this Article
            III, of the holders of Senior Indebtedness in respect of
            assets of the Company of any kind or character, whether
            cash, property or securities, received upon the exercise of
            any such remedy.

                 The Company shall give prompt written notice to a
            Responsible Officer of the Trustee of any dissolution,
            winding up, liquidation, or reorganization of the Company
            within the meaning of this Section 3.2.  The Trustee shall
            be entitled to assume that no such event has occurred unless
            the Company has given such written notice.  Upon any payment
            or distribution of assets of the Company referred to in this
            Article III, the Trustee and the holders of the Debentures
            shall be entitled to rely upon any order or decree of a
            court of competent jurisdiction in which such dissolution,
            winding up, liquidation or reorganization proceedings are
            pending, and upon a certificate of the receiver,

                                  -24-




            trustee in bankruptcy, liquidating trustee, agent or other
            person making any such payment or distribution, delivered to
            the Trustee or to the holders of the Debentures, for the
            purpose of ascertaining the persons entitled to participate
            in such distribution, the holders of Senior Indebtedness and
            other indebtedness of the Company, the amount thereof or
            payable thereon, the amount or amounts paid or distributed
            thereon and all other facts pertinent thereto or to this
            Article III.

                 In the event that the Trustee determines, in good
            faith, that further evidence is required with respect to the
            right of any person as a holder of Senior Indebtedness to
            participate in any payment or distribution pursuant to this
            Section 3.2, the Trustee may request such person or
            representative thereof to furnish evidence to the reasonable
            satisfaction of the Trustee as to the amount of Senior
            Indebtedness held by such person, the extent to which such
            person is entitled to participate in such payment or
            distribution, and other facts pertinent to the rights of
            such person under this Section 3.2.  If such evidence is not
            furnished, the Trustee may defer any payment to such person
            or such representative pending judicial determination as to
            the right of such person to receive such payment.

                 No payment on account of the principal of, premium, if
            any, or interest on the Debentures shall be made, if, at the
            time of such payment or immediately after giving effect
            thereto, there shall exist a default in the payment of the
            principal of, premium, if any, or interest on any Senior
            Indebtedness (whether at expressed maturity, acceleration
            thereof or otherwise), unless and until such default shall
            have been cured or waived or shall have ceased to exist;
            provided, however, that, notwithstanding the foregoing, the
            following shall be permitted: payments made in Capital Stock
            or in warrants, rights or options to purchase or acquire
            Capital Stock, payments made on account of any sinking fund
            and made in Debentures owned by the Company or any
            subsidiary prior to the time such default shall have
            occurred and payments made through the exchange of other
            debt obligations of the Company for such Debentures in
            accordance with the terms of such Debentures, provided that
            such debt obligations are subordinated to Senior
            Indebtedness at least to the extent that the Debentures for
            which they are exchanged are so subordinated pursuant to
            this Article III.

                 If any Event of Default described in Section 7.1 occurs
            (under the circumstances when the provisions of the first
            paragraph of this Section 3.2 shall not be applicable) and
            as a result the Debentures then Outstanding of any series
            are declared due and payable, and such declaration has not
            been rescinded or annulled, all principal and premium, if
            any, of all Senior Indebtedness then due, or thereafter
            declared to be due, pursuant to the terms of said Senior
            Indebtedness, within 90 days from notice of said Event of
            Default given by the Company to holders of Senior
            Indebtedness, and all interest then due upon Senior

                                  -25-




            Indebtedness, shall first be paid in full before any payment
            is made on account of the principal, premium, if any, or
            interest on any Debenture.

                 Nothing in this Section 3.2 shall apply to claims of,
            or payments to, the Trustee pursuant to Section 11.2.

                 SECTION 3.3.      Debentures may be paid prior to
            dissolution, etc. Nothing contained in this Article III or
            elsewhere in this Indenture, or in any of the Debentures,
            shall prevent (a) the Company, at any time except under the
            conditions described in Section 3.2 hereof or during the
            pendency of any dissolution or winding up or total or
            partial liquidation or reorganization proceedings therein
            referred to, from making payments at any time of principal
            of, premium, if any, or interest on the Debentures or from
            depositing with the Trustee or any Paying Agent moneys for
            such payments, (b) the application by the Trustee or any
            Paying Agent of any moneys deposited with it under this
            Indenture to the payment of or on account of the principal
            of, premium, if any, or interest on the Debentures to the
            Debentureholders entitled thereto, provided that such
            payment was not, to the actual knowledge of the Trustee or
            any Paying Agent, prohibited by the provisions of Section
            3.2 on the date such moneys were so deposited, or (c) the
            retention by the holders of Debentures of moneys so applied
            and paid to them on account of the principal of, premium, if
            any, or interest on the Debentures, whether or not at the
            time of application described in clause (b) or payment
            described in this clause (c), payment of the principal of,
            premium, if any, or interest on the Debentures would then be
            precluded pursuant to Section 3.2.

                 Notwithstanding the provisions of Section 3.1 or any
            other provision of this Indenture, the Trustee and any
            Paying Agent shall not be charged with knowledge of the
            existence of any Senior Indebtedness, or of the occurrence
            of any default with respect to Senior Indebtedness of the
            character described in Section 3.2, or of any other facts
            which would prohibit the making of any payment of moneys to
            or by the Trustee or such payment agent, unless and until a
            Responsible Officer of the Trustee and the Paying Agent
            shall have received written notice thereof at its principal
            office from the Company or from a person the Trustee and the
            Paying Agent reasonably believes to be a holder of such
            Senior Indebtedness stating that facts exist prohibiting the
            making of such payment or specifying such facts, and, prior
            to the receipt of any such written notice by a Responsible
            Officer of the Trustee, the Trustee or the Paying Agent
            shall be entitled in all respects to assume that no such
            facts exist; provided, that, if two Business days prior to
            the date upon which by the terms hereof any such moneys may
            become payable for any purpose (including, without
            limitation, the payment of the principal of, premium, if
            any, or interest on any Debenture) the Trustee or such
            Paying Agent shall not have received with respect to such
            moneys the notice provided for in

                                  -26-




            this Section 3.3, then, anything herein contained to the
            contrary notwithstanding, the Trustee and such Paying Agent
            shall have full power and authority to receive such moneys
            and are directed to apply the same to the purpose for which
            they were received, and shall not be affected by any notice
            to the contrary which may be received by it after such date.

                 SECTION 3.4.      Rights of holders of Senior
            Indebtedness not to be impaired, etc.  No right of any
            present or future holder of any Senior Indebtedness of the
            Company to enforce subordination as herein provided shall at
            any time in any way be prejudiced or impaired by any act or
            failure to act on the part of the Company or by any act or
            failure to act, in good faith, by any such holder, or by any
            noncompliance by the Company with the terms, provisions and
            covenants of this Indenture, regardless of any knowledge
            thereof any such holder may have or be otherwise charged
            with.

                 The provisions of this Article III are intended to be
            for the benefit of, and shall be enforceable directly by,
            the holders of Senior Indebtedness. Neither the Trustee nor
            any Paying Agent shall be deemed to owe any fiduciary duty
            to the holders of Senior Indebtedness and shall not be
            liable to any such holder if any of them shall mistakenly
            pay over or distribute to the holders of the Debentures, the
            Company or any other person, money or assets to which the
            holders of Senior Indebtedness shall be entitled by virtue
            of this Article III or otherwise.  With respect to the
            holders of Senior Indebtedness, the Trustee undertakes to
            perform and observe only such covenants and obligations as
            are specifically set forth in this Article III and no
            implied covenants and obligations with respect to such
            holders of Senior Indebtedness should be read into this
            Indenture against the Trustee.

                 SECTION 3.5.      Authorization to Trustee to take
            action to effectuate subordination.  Each holder of a
            Debenture of any series by his acceptance thereof authorizes
            the Trustee and the Paying Agent on his behalf to take such
            action as may be necessary or appropriate to effectuate as
            between the Debentureholders of such series and the holders
            of Senior Debentures the subordination provided in this
            Article III and appoints the Trustee his attorney-in-fact
            for any and all such purposes.

                 SECTION 3.6.      Trustee's rights as holder of Senior
            Indebtedness.  The Trustee shall be entitled to all the
            rights set forth in this Article III with respect to any
            Senior Indebtedness at any time held by it, to the same
            extent as any other holder of Senior Indebtedness, and
            nothing in Section 11.9 or elsewhere in this Indenture shall
            be construed to deprive the Trustee of any of its rights as
            such holder.

                                  -27-



                 SECTION 3.7.      Trustee's disclaimer.  The Trustee
            makes no representations as to the validity or adequacy of
            this Indenture or the Debentures, it shall not be
            accountable for the Company's use of proceeds from the
            Debentures, and it shall not be responsible for any
            statement in any Debentures other than its authentication.

                 SECTION 3.8.      Application by Trustee of monies or
            U.S. Government Obligations deposited with it.  Money or
            U.S. Government Obligations deposited in trust with the
            Trustee pursuant to and in accordance with Section 6.1 shall
            be for the sole benefit of Debentureholders and, to the
            extent allocated for the payment of Debentures, shall not be
            subject to the subordination provisions of this Article III,
            if the same are deposited in trust prior to the happening of
            any event specified in Section 3.2.  Otherwise, any deposit
            of moneys or U.S. Government Obligations by the Company with
            the Trustee or any Paying Agent (whether or not in trust)
            for the payment of the principal of, premium, if any, or
            interest on any Debentures shall be subject to the
            provisions of Sections 3.1 and 3.2 except that, if prior to
            the date on which by the terms of this Indenture any such
            monies may become payable for any purpose (including,
            without limitation, the payment of the principal of,
            premium, if any, or interest on any Debenture) the Trustee
            shall not have received with respect to such moneys the
            notice provided for in Section 3.3, then the Trustee or the
            Paying Agent shall have full power and authority to receive
            such moneys and U.S. Government Obligations and to apply the
            same to the purpose for which they were received, and shall
            not be affected by any notice to the contrary which may be
            received by it on or after such date.  This Section 3.8
            shall be construed solely for the benefit of the Trustee and
            Paying Agent and, as to the first sentence hereof, the
            Debentureholders, and shall not otherwise affect the rights
            of holders of Senior Indebtedness.

                 SECTION 3.9.      Trustee Compensation not prejudiced.
            Nothing in this Article III shall apply to claims of or
            payment to the Trustee pursuant to Section 11.2.

                               ARTICLE IV

                        COVENANTS OF THE COMPANY

                 The Company covenants and agrees as follows:

                 SECTION 4.1  Payment of Principal and interest.  The
            Company will for the benefit of each series of Debentures
            duly and punctually pay or cause to be paid the principal
            of, premium, if any, and interest on the Debentures of such
            series at the times

                                  -28-




            and place and in the manner specified in this Indenture and
            in the Debentures of such series.  At the option of the
            Company, interest on the Debentures shall be payable without
            presentation of such Debentures by a check to the registered
            holder.

                 SECTION 4.2  Maintenance of office or agency.  So long
            as any of the Debentures of any series remain unpaid, the
            Company will at all times keep an office or agency in where
            Debentures of such series may be presented for registration
            of transfer and exchange as in this Indenture provided,
            where notices and demands with respect to the Debentures and
            this Indenture may be served and where the Debentures may be
            presented for payment or, for Debentures of each series that
            is convertible, for conversion.  The principal office of the
            Trustee shall be the office or agency for all of the
            aforesaid purposes, unless the Company shall maintain some
            other office or agency with respect to the Debentures of any
            series for such purposes and shall give the Trustee written
            notice of the location thereof.  In case the Company shall
            fail to maintain such office or agency, presentations may be
            made and notices and demands may be served at the principal
            office of the Trustee.

                 The Company shall keep, at said office or agency, a
            register or registers in which, subject to such reasonable
            regulations as it may prescribe, the Company shall register
            or cause to be registered Debentures of each series and
            shall register or cause to be registered the transfer or
            exchange of Debentures of each series as in Article II
            provided.  Such register or registers shall be in written
            form in the English language or any other form capable of
            being converted into written form within a reasonable time.
            At all reasonable times, such register or registers shall be
            open for inspection by the Trustee.

                 SECTION 4.3  Corporate existence.  So long as any of
            the Debentures remain unpaid, the Company will at all times
            (except as otherwise provided or permitted elsewhere in this
            Indenture) do or cause to be done all things necessary to
            preserve and keep in full force and effect its corporate
            existence.

                 SECTION 4.4  Restrictions on mergers, sales and
            consolidations.  So long as any of the Debentures remain
            unpaid, the Company will not consolidate or merge with or
            sell, convey or lease all or substantially all of its
            property to any other corporation except as permitted in
            Article X hereof.

                 SECTION 4.5  Further assurances.  From time to time
            whenever requested by the Trustee, the Company will execute
            and deliver such further instruments and assurances and do
            such further acts as may be reasonably necessary or proper
            to carry out more effectually the purposes of this Indenture
            or to secure the rights and remedies hereunder of the
            holders of the Debentures of any series.

                                  -29-



                 SECTION 4.6  File certain reports and information with
            the Trustee and the Securities and Exchange Commission -
            transmit to Debentureholders summaries of certain documents
            filed with the Trustee - furnish list of Debentureholders to
            the Trustee.  The Company will:

                       (a)  file with the Trustee, within 15 days after
                 the Company files the same with the Securities and
                 Exchange Commission, copies of the annual reports and
                 of the information, documents and other reports which
                 the Company may be required to file with the Securities
                 and Exchange Commission pursuant to Section 13 or
                 Section 15(d) of the Securities Exchange Act of 1934
                 (or copies of such portions thereof as may be
                 prescribed by the Securities and Exchange Commission);
                 or, if the Company is not required to file with the
                 Securities and Exchange Commission information,
                 documents or reports pursuant to either Section 13 or
                 Section 15(d) of the Securities Exchange Act of 1934,
                 then the Company will file with the Trustee and will
                 file with the Securities and Exchange Commission, in
                 accordance with rules and regulations prescribed by the
                 Securities and Exchange Commission, such of the
                 supplementary and periodic information, documents and
                 reports required pursuant to Section 13 of the
                 Securities Exchange Act of 1934 in respect of a
                 security listed and registered on a national securities
                 exchange as may be prescribed in such rules and
                 regulations;

                       (b)  file with the Trustee and the Securities and
                 Exchange Commission, in accordance with the rules and
                 regulations prescribed from time to time by the
                 Securities and Exchange Commission, such additional
                 information, documents and reports with respect to
                 compliance by the Company with the conditions and
                 covenants provided for in this Indenture as may be
                 required by such rules and regulations;

                       (c)  transmit to the Debentureholders, in the
                 manner and to the extent provided in subdivision (c) of
                 Section 11.10, such summaries of any information,
                 documents and reports required to be filed with the
                 Trustee pursuant to the provisions of subdivisions (a)
                 and (b) of this Section 4.6 as may be required by the
                 rules and regulations of the Securities and Exchange
                 Commission; and

                       (d)  furnish or cause to be furnished to the
                 Trustee, not more than 15 days after each record date
                 (but in no event less frequently than every six months)
                 for the payment of interest with respect to Debentures
                 of any series, and at such other times as the Trustee
                 may request in writing, within 30 days after receipt by
                 the Company of any such request, a list in such form as
                 the Trustee may reasonably require containing all
                 information in the possession or control of the Company
                 or of any paying agent, other than the

                                  -30-




                 Trustee, as to the names and addresses of the holders
                 of Debentures of such series obtained since the date as
                 of which the next previous list, if any, was furnished;
                 provided, that so long as the Trustee is Debenture
                 registrar for such series, no such list need be
                 furnished. Any such list may be dated as of a date not
                 more than 15 days prior to the time such information is
                 furnished or caused to be furnished, and need not
                 include information received after such date (excluding
                 from any such list names and addresses received by the
                 Trustee in its capacity as Debenture registrar).

                 SECTION 4.7  File statement by officers annually with
            the Trustee.  Within 120 days after the close of the fiscal
            year ending                        and within 120 days after
            the close of each fiscal year thereafter, the Company will
            file with the Trustee a brief certificate from the principal
            executive officer, principal financial officer or principal
            accounting officer as to his or her knowledge of the
            Company's compliance with all conditions and covenants under
            this Indenture.  For purposes of this paragraph, such
            compliance shall be determined without regard to any period
            of grace or requirement of notice provided under this
            Indenture.

                 At the time such Officers' Certificate is filed, the
            Company will also file with the Trustee a letter or
            statement of the independent accountants who shall have
            certified the financial statements of the Company for its
            preceding fiscal year in connection with the annual report
            of the Company to its shareholders for such year to the
            effect that, in making the examination necessary for
            certification of such financial statements, they have
            obtained no knowledge of any default by the Company in the
            performance or fulfillment of any covenant, agreement or
            condition contained in this Indenture, which default remains
            uncured at the date of such letter or statement, or, if they
            shall have obtained knowledge of any such uncured default,
            specifying in such letter or statement such default or
            defaults and the nature and status thereof, it being
            understood that such accountants shall not be liable
            directly or indirectly for failure to obtain knowledge of
            any such default or defaults, and that nothing contained in
            this Section 4.7 shall be construed to require such
            accountants to make any investigation beyond the scope
            required in connection with such examination.

                 SECTION 4.8  Duties of Paying Agent.  The Company will
            cause each Paying Agent for the Debentures of any series
            other than the Trustee to execute and deliver to the Trustee
            an instrument in which such agent shall agree with the
            Trustee:

                       (a)  that it will hold all sums held by it as
                 such agent for the payment of the principal of,
                 premium, if any, or interest on the Debentures of such
                 series (whether such sums have been paid to it by the
                 Company or by any other obligor on the Debentures of
                 such series) in trust for the benefit of

                                  -31-




                 the holders of the Debentures of such series;

                       (b)  that it will give the Trustee written notice
                 of any failure by the Company (or by any other obligor
                 on the Debentures of such series) to make any payment
                 of the principal of, premium, if any, or interest on
                 the Debentures of such series when the same shall be
                 due and payable; and

                       (c)  that it will, at any time during the
                 continuance of any Event of Default with respect to
                 such series, upon the written request of the Trustee,
                 forthwith pay to the Trustee all sums so held in trust
                 by such Paying Agent.

            If the Company acts as its own paying Agent for the
            Debentures of any series, it will, on or before each due
            date of the principal of, premium, if any, or interest on
            the Debentures of such series, set aside and segregate and
            hold in trust for the benefit of the holders of the
            Debentures of such series a sum sufficient to pay such
            principal, premium, if any, or interest and will notify the
            Trustee of such action or any failure to take such action.

                 Whenever the Company shall have one or more Paying
            Agents for any series of Debentures, it will, on or before
            each due date of the principal of, premium, if any, or
            interest on any Debentures of such series, deposit with the
            Paying Agent or Agents for the Debentures of such series a
            sum, by 10:00 a.m. New York time in immediately available
            funds on the payment date, sufficient to pay the principal,
            premium, if any, or interest so becoming due with respect to
            the Debentures of such series, and (unless such paying agent
            is the Trustee) the Company will promptly notify the Trustee
            in writing of any failure so to act.

                 The Company may at any time, for the purpose of
            obtaining the satisfaction and discharge of this Indenture
            with respect to the Debentures of one or more series or for
            any other purpose, pay, or by Company order direct any
            Paying Agent for such series to pay, to the Trustee all sums
            held in trust by the Company or such Paying Agent, such sums
            to be held by the Trustee upon the same trusts as those upon
            which such sums were held by the Company or such Paying
            Agent; and, upon such payment by any Paying Agent to the
            Trustee, such Paying Agent shall be released from all
            further liability with respect to such payment.

                 Anything in this Section 4.8 to the contrary
            notwithstanding, the agreement to hold sums in trust as
            provided in this Section 4.8 shall be subject to the
            provisions of Section 6.3.

                               ARTICLE V

                 REDEMPTION OF DEBENTURES; SINKING FUND

                 SECTION 5.1  Applicability of Article.  Debentures of
            any series which are redeemable before their stated maturity
            at the election of the Company or through the operation of
            any sinking fund for the retirement of Debentures of such
            series shall be redeemable in accordance with their terms
            established pursuant to Section 2.2 and (except as otherwise
            established pursuant to Section 2.2 for Debentures of such
            series) in accordance with this Article.

                 SECTION 5.2  Notice of redemption to be given to
            Trustee - deposit of cash (or other form of payment) with
            Trustee - selection by Trustee of Debentures to be redeemed.
            Not less than 30 days (or such lesser number of days as the
            Trustee shall approve) nor more than 60 days (or such
            greater number of days as the Trustee shall approve) prior
            to the date fixed by the Company for the redemption at the
            option of the Company of any Debentures of any series which
            are subject to redemption or portions thereof, the Company
            shall give written notice, by delivering a Company Order to
            the Trustee, stating the aggregate principal amount of
            Debentures of such series which the Company elects to redeem
            and the date and place fixed for redemption, that the
            Company, in the case of any redemption of Debentures subject
            to any restrictions on such redemption provided in the terms
            of Debentures of such series established pursuant to Section
            2.2 or elsewhere in this Indenture, is in compliance with
            such restrictions.  On or before 10:00 a.m. New York time of
            the date fixed for redemption, the Company shall deposit
            with the Trustee or the Paying Agent money in immediately
            available funds on such redemption date (or other form of
            payment if permitted by the terms of such Debentures) an
            amount sufficient to redeem on the date fixed for redemption
            all the Debentures of such series or portions thereof to be
            redeemed, other than any Debentures of such series called
            for redemption on such date which have been converted prior
            to the date of such deposit, at the appropriate redemption
            price, together with any accrued interest to the date fixed
            for redemption.  If less than all the Debentures then
            Outstanding of such series are to be redeemed, the Trustee
            shall select, substantially pro rata or by lot, in such
            manner as it shall deem appropriate and fair, in its sole
            discretion, the numbers of the Debentures to be redeemed as
            a whole or in part, and shall thereafter promptly notify the
            Company in writing of the numbers of the Debentures to be
            redeemed; provided, however, that Debentures of such series
            registered in the name of the Company shall be excluded from
            any such selection for redemption until all Debentures of
            such series not so registered shall have been previously
            selected for redemption. For the purpose of such selection
            in case of redemption of less than all of the Debentures of
            any series, the Trustee and the Company shall have the
            option to treat as Outstanding Debentures any Debentures of

                                  -33-




            such series which are surrendered for conversion after the
            fifteenth day immediately preceding the mailing of the
            notice of such redemption, and need not treat as Outstanding
            Debentures any Debentures authenticated and delivered during
            such period in exchange for the unconverted portion of any
            Debentures converted in part during such period.  In case
            any Debenture shall be redeemed in part only, the notice of
            redemption shall specify the principal amount thereof to be
            redeemed and shall state that, upon surrender thereof for
            redemption, a new Debenture or new Debentures of the same
            series of an aggregate principal amount equal to the
            unredeemed portion of such Debenture will be issued in lieu
            thereof; and in such case the Company shall execute and the
            Trustee or the Authenticating Agent shall authenticate and
            deliver such new Debenture or Debentures of such series to
            or upon the written order of the Debentureholder, at the
            expense of the Company. Provisions of this Indenture that
            apply to Debentures called for redemption also apply to
            portions of Debentures called for redemption.

                 Upon or after the receipt of such notice, the Trustee,
            in the name of the Company and as its agent, shall mail by
            first-class mail, postage prepaid, to each registered holder
            of a Debenture to be redeemed in whole or in part at his
            last address appearing on the registration books of the
            Company, a notice of redemption.  Such notice of redemption
            shall identify the Debentures to be so redeemed in whole or
            in part and whether such Debentures are to be redeemed in
            whole or in part and shall state: (i) the date fixed for
            redemption; (ii) the redemption price at which Debentures
            are to be redeemed and method of payment, if other than in
            cash; (iii) if applicable, the current conversion price or
            rate; (iv) if applicable, that the right of the
            Debentureholder to convert Debentures called for redemption
            shall terminate at the close of business on the date fixed
            for redemption (or such other day as may be specified as
            contemplated by Section 2.2 for Debentures of any series);
            (v) if applicable, that Debentureholders who want to convert
            Debentures called for redemption must satisfy the
            requirements for conversion contained in such Debentures;
            (vi) that, subject to Section 13.4, interest, if any,
            accrued to the date fixed for redemption will be paid as
            specified in said notice and that on and after said date
            interest thereon shall cease to accrue; (vii) the provision
            of the Debenture or this Indenture under which the
            redemption is being made; and (viii) that the Company so
            elects to redeem such Debentures or portions thereof at the
            place or places specified in such notice.  Such notice shall
            be mailed not later than the tenth, and not earlier than the
            sixtieth, day before the date fixed for redemption.  Any
            notice which is mailed in the manner herein provided shall
            be conclusively presumed to have been duly given, whether or
            not the holder receives such notice; and failure duly to
            give such notice by mail, or any defect in such notice, to
            the holder of any Debenture designated for redemption as a
            whole or in part shall not affect the validity of the
            proceedings for the redemption of any other Debenture.


                                  -34-



                 The Company shall pay to the Trustee the cost of
            mailing notices of redemption and any other necessary
            expenses incurred by the Trustee in connection therewith.

                 SECTION 5.3.  Debentures called for redemption to
            become due - rights of holders of redeemed Debentures -
            return of funds on conversion.  The notice of election to
            redeem having been mailed as hereinbefore provided, the
            Debentures or portions thereof called for redemption shall
            become due and payable on the redemption date at the
            applicable redemption price, together with interest accrued
            to the date fixed for redemption, at the place or places
            specified in such notice, and if cash (or other form of
            payment if permitted by the terms of such Debentures) in the
            amount necessary to redeem such Debentures or portions
            thereof has been deposited with the Trustee, interest on
            such Debentures or portions thereof shall cease to accrue
            from and after the date fixed for redemption (unless the
            Company shall default in the payment of the redemption
            price, plus accrued interest, if any) and the right to
            convert such Debentures or portions thereof, if the terms of
            such Debentures provide for conversion pursuant to Section
            2.2, shall terminate at the close of business on the date
            fixed for redemption or such other day as may be specified
            as contemplated by Section 2.2 for Debentures of such
            series.  The respective registered holders of Debentures or
            portions thereof so called for redemption shall be entitled
            to receive payment of the applicable redemption price,
            together with interest accrued to the date fixed for
            redemption on or after the date fixed for redemption (unless
            the Company shall default in the payment of the redemption
            price, plus accrued interest, if any), upon presentation and
            surrender at the place or places of payment specified in
            such notice.  Notwithstanding the foregoing, subject to
            Section 13.4, if the record date for payment or interest is
            on or prior to the redemption date, such interest shall be
            payable to the persons who are holders of such Debentures on
            such record date according to the terms of such Debentures
            and Section 2.12.

                 If any Debenture called for redemption pursuant to
            Section 5.1 is converted pursuant to Article XIII, any
            monies deposited with the Trustee for the purpose of paying
            or redeeming any such Debenture shall be promptly paid to
            the Company.

                 SECTION 5.4  Credits against sinking fund.  Against any
            one or more sinking fund payments to be made pursuant to the
            terms of the Debentures of any series providing for a
            sinking fund, the Company may elect, by delivery of an
            Officers' Certificate to the Trustee, at least 45 days prior
            to the sinking fund payment date (or such shorter period as
            may be acceptable to the Trustee or is otherwise specified
            as contemplated by Section 2.2 for Debentures of any
            series), to take credit for any Debentures of such series or
            portions thereof acquired or redeemed by the Company,
            pursuant to the terms of such Debentures or through the
            application of permitted optional sinking fund payments
            pursuant to the terms of

                                  -35-



            such Debentures, which have not previously been used by the
            Company for the purposes permitted in this Section 5.4 and
            for any Debentures which have been converted pursuant to the
            terms of such Debentures.  Such Debentures shall be received
            and credited for such purpose by the Trustee at the
            redemption price specified in such Debentures for redemption
            through operation of the sinking fund and the amount of such
            sinking fund payment shall be reduced accordingly. Upon any
            such election the Company shall receive credit against such
            sinking fund payments required to be made in the order in
            which they are to be made. Any Debenture for which credit is
            elected to be taken which shall not theretofore have been
            delivered to the Trustee for cancellation shall at the time
            of such election be delivered to the Trustee for
            cancellation by the Trustee.

                 SECTION 5.5  Redemption through sinking fund.  Each
            sinking fund payment made under the terms of the Debentures
            of any series established pursuant to Section 2.2 shall be
            applied to the redemption of Debentures of such series on
            the date for redemption specified in the Debentures of such
            series next succeeding such sinking fund payment date;
            provided, however, if at any time the amount of cash to be
            paid into the sinking fund for such series on the next
            succeeding sinking fund payment date, together with any
            unused balance of any preceding sinking fund payment or
            payments for such series, shall not exceed in the aggregate
            $10,000, the Trustee, unless requested by the Company, shall
            not give notice of the redemption of Debentures of such
            series through the operation of the sinking fund on the
            succeeding date for redemption specified in the Debentures
            of such series.  At least 45 days (or such lesser number of
            days as the Trustee shall approve) prior to the date on
            which a sinking fund payment with respect to the Debentures
            of any series is due, the Company shall give written notice
            to the Trustee of the principal amount of Debentures of such
            series registered in the name of the Company (which shall be
            excluded from such redemption) and the Trustee shall select,
            substantially pro rata or by lot, in such manner as it shall
            deem appropriate and fair, the principal amount of
            Debentures of such series to be redeemed in accordance with
            the terms of the Debentures of such series after allowance
            for any credit elected under Section 5.4 and shall, in the
            name and at the expense of the Company and as its agent,
            give notice of such redemption, all in the manner provided
            for in Section 5.2, except that such notice shall state that
            the Debentures of such series are being redeemed for the
            sinking fund.  The notice of redemption having been mailed
            as hereinbefore provided, the Debentures or portions thereof
            called for redemption shall become due and payable on the
            next succeeding date for redemption specified in the
            Debentures of such series at the sinking fund redemption
            price thereof, all in the manner and with the effect
            provided for in Section 5.3.

                 Any sinking fund payment not so required to be applied
            to the redemption of Debentures of any series on the date
            for redemption

                                  -36-




            specified in the Debentures of such series next succeeding
            any sinking fund payment date may, at the direction of the
            Company as evidenced by a Company Order, be applied by the
            Trustee prior to the forty-fifth day preceding the next
            following sinking fund payment date for such series, in such
            manner and from time to time, in such amount as the Company
            may direct the Trustee in writing, so far as such moneys
            shall be adequate, to the purchase for the sinking fund of
            Debentures of such series or portions thereof, in the open
            market, from the Company or otherwise, at prices (exclusive
            of accrued interest and brokerage commissions) not in excess
            of the sinking fund redemption price for such series.  The
            Company agrees to pay to the Trustee, upon request, accrued
            interest and brokerage commissions paid by the Trustee with
            respect to any Debentures of such series so purchased by the
            Trustee and such accrued interest and brokerage commissions
            shall not be charged against the sinking fund for such
            series.

                 Any unused balance of sinking fund moneys with respect
            to Debentures of any series remaining in the hands of the
            Trustee on the forty-fifth day preceding the sinking fund
            payment date for such series in any year shall be added to
            any sinking fund payment for such series to be made in cash
            in such year, and together with such payment, if any, shall
            be applied to the redemption or purchase of Debentures of
            such series in accordance with the provisions of this
            Section 5.5, provided that any sinking fund moneys so
            remaining in the hands of the Trustee after the date
            specified in the Debentures of such series and not utilized
            in the purchase of Debentures of such series as provided in
            this Section 5.5 shall be applied by the Trustee to the
            payment of Debentures at maturity.

                 SECTION 5.6  Debentures no longer Outstanding after
            notice to Trustee and deposit of cash.  If the Company,
            having given notice to the Trustee as provided in Section
            5.1 or 5.2, shall have deposited with the Trustee or the
            Paying Agent, for the benefit of the holders of any
            Debentures of any series or portions thereof called for
            redemption in whole or in part cash or other form of payment
            if permitted by the terms of such Debentures (which amount
            shall be immediately due and payable to the holders of such
            Debentures or portions thereof) in the amount necessary so
            to redeem all such Debentures or portions thereof on the
            date fixed for redemption and provision satisfactory to the
            Trustee shall have been made for the giving of notice of
            such redemption, such Debentures, or portions thereof, shall
            thereupon, for all purposes of this Indenture, be deemed to
            be no longer Outstanding, and the holders thereof shall be
            entitled to no rights thereunder or hereunder, except the
            right to receive payment of the applicable redemption price,
            together with interest accrued to the date fixed for
            redemption, on or after the date fixed for redemption of
            such Debentures or portions thereof and the right to convert
            such Debentures or portions thereof, if the terms of such
            Debentures provide for convertibility pursuant to Section
            2.2, at or prior to the close

                                  -37-




            of business on the date fixed for redemption.

                 SECTION 5.7.  Conversion arrangement on call for
            redemption.  In connection with any redemption of
            Debentures, the Company may arrange for the purchase and
            conversion of any Debentures called for redemption by an
            agreement with one or more investment bankers or other
            purchasers to purchase such Debentures by paying to the
            Trustee or the Paying Agent in trust for the
            Debentureholders, on or before 10:00 a.m., New York time, on
            the redemption date, an amount no less than the redemption
            price, together with interest, if any, accrued to the
            redemption date of such Debentures, in immediately available
            funds. Notwithstanding anything to the contrary contained in
            this Article V, the obligation of the Company to pay the
            redemption price of such Debentures, including all accrued
            interest, if any, shall be deemed to be satisfied and
            discharged to the extent such amount is so paid by such
            purchasers.  If such an agreement is entered into, any
            Debentures not duly surrendered for conversion by the
            holders thereof may, at the option of the Company, be
            deemed, to the fullest extent permitted by law, acquired by
            such purchasers from such holders and (notwithstanding
            anything to the contrary contained in Article XIII)
            surrendered by such purchasers for conversion, all as of
            immediately prior to the close of business on the last day
            on which Debentures of such series called for redemption may
            be converted in accordance with this Indenture and the terms
            of such Debentures, subject to payment of the above amount
            aforesaid.  The Trustee or the Paying Agent shall hold and
            pay to the Debentureholders whose Debentures are selected
            for redemption any such amount paid to it in the same manner
            as it would moneys deposited with it by the Company for the
            redemption of Debentures. Without the Trustee's and the
            Paying Agent's prior written consent, no arrangement between
            the Company and such purchasers for the purchase and
            conversion of any Debentures shall increase or otherwise
            affect any of the powers, duties, responsibilities or
            obligations of the Trustee as set forth in this Indenture,
            and the Company agrees to indemnify the Trustee from, and
            hold it harmless against, any loss, liability or expense
            arising out of or in connection with any such arrangement
            for the purchase and conversion of any Debentures between
            the Company and such purchasers, including the costs and
            expenses incurred by the Trustee and the Paying Agent in the
            defense of any claim or liability arising out of or in
            connection with the exercise or performance of any of its
            powers, duties, responsibilities or obligations under this
            Indenture.

                               ARTICLE VI

                SATISFACTION AND DISCHARGE OF INDENTURE

                 SECTION 6.1  Satisfaction and discharge of Indenture
            with respect to Debentures of any series.  If (a) the
            Company shall deliver to the Trustee for cancellation all
            Debentures of any series theretofore authenticated (other
            than any such Debentures

                                  -38-




            which shall have been destroyed, lost or stolen and in lieu
            of or in substitution for which other such Debentures shall
            have been authenticated and delivered or Debentures for
            whose payment money (or other form of payment if permitted
            by the terms of such Debentures) has theretofore been held
            in trust and thereafter repaid to the Company, as provided
            in Section 6.3) and not theretofore cancelled, or (b) the
            Company shall irrevocably deposit (subject to Section 6.3)
            with the Trustee or Paying Agent as trust funds the entire
            amount in cash or U.S. Government Obligations sufficient to
            pay at maturity or upon redemption all of the Debentures of
            such series (other than any Debentures which shall have been
            destroyed, lost or stolen and in lieu of or in substitution
            for which other Debentures shall have been authenticated and
            delivered or Debentures for whose payment money (or other
            form of payment if permitted by the terms of such
            Debentures) has theretofore been held in trust and
            thereafter repaid to the Company, as provided in Section
            6.3) not theretofore paid, surrendered or delivered to the
            Trustee for cancellation, including the principal, premium,
            if any, and interest due or to become due to such date of
            maturity or redemption date, as the case may be, and if in
            either case the Company shall also pay or cause to be paid
            all other sums payable hereunder by the Company and the
            Company shall deliver to the Trustee an Officers'
            Certificate and an Opinion of Counsel, each stating that in
            the opinion of the signers all conditions precedent to the
            satisfaction and discharge of this Indenture with respect to
            the Debentures of such series have been complied with (and,
            in the event that such deposit shall be made more than one
            year prior to the maturity of the Debentures of such series,
            such Opinion of Counsel shall also state that such deposit
            will not result in an obligation of the Company, the Trustee
            or the trust fund created by such deposit to register as an
            investment company under the Investment Company Act of 1940,
            as amended) and a certificate (upon which the Trustee may
            rely) of a firm of independent public accountants of
            recognized national standing selected by the Board of
            Directors (who may be the regular accountants employed by
            the Company) stating that the cash, if any, and U.S.
            Government Obligations, if any, deposited as set forth above
            are sufficient to pay at maturity or upon redemption all of
            the Debentures of such series as set forth above, then,
            except with respect to the remaining rights of conversion of
            any Debentures the terms of which provide for conversion
            (which shall continue in full force and effect pursuant to
            the terms set forth in Article XIII to the extent provided
            for in such terms) or to rights of exchange or registration
            of transfer or of the Company's right of optional redemption
            of any Debentures of such series, this Indenture shall cease
            to be of further effect with respect to the Debentures of
            such series, and the Trustee, on demand of and at the cost
            and expense of the Company, shall execute proper instruments
            acknowledging satisfaction of and discharging this Indenture
            with respect to the Debentures of such series.
            Notwithstanding the satisfaction and discharge of this
            Indenture with respect to the Debentures of such series, the

                                  -39-




            obligations of the Company to the Trustee under Section 11.2
            shall survive, and if moneys or U.S. Government Obligations
            shall have been irrevocably deposited with the Trustee or
            Paying Agent pursuant to clause (b) of this Section, the
            obligations of the Trustee under Section 6.2 and the first
            paragraph of Section 6.3 shall survive.

                 In order to have money available on a payment date to
            pay the principal of, premium, if any, or interest, if any,
            on the Debentures, the U.S. Government Obligations shall be
            payable as to principal or interest on or before such
            payment date in such amounts as will provide the necessary
            money.  Such U.S. Government Obligations shall not be
            callable at the issuer's option.

                 SECTION 6.2  Deposits for payment or redemption of
            Debentures to be held in trust.  Subject to the provisions
            of Article III and the provisions hereinafter contained in
            this Article VI, any moneys or U.S. Government Obligations
            (or other form of payments if permitted by the terms of such
            Debenture) which at any time shall be deposited by the
            Company, or on its behalf with the Trustee or the Paying
            Agent, for the purpose of paying or redeeming any of the
            Debentures of any series shall be held in trust and applied
            by the Trustee to the payment to the holders of the
            particular Debentures for the payment or redemption of which
            such moneys (or other form of payments if permitted by the
            terms of such Debenture) have been deposited, of all sums
            due and to become due thereon for principal, premium, if
            any, and interest, upon presentation and surrender of such
            Debentures at the office or agency of the Company maintained
            as provided in this Indenture.  Neither the Company nor the
            Trustee (except as provided in Section 11.2) nor any Paying
            Agent shall be required to pay interest on any moneys so
            deposited.

                 SECTION 6.3  Repayment of moneys.  Any moneys or U.S.
            Government Obligations deposited with the Trustee or any
            Paying Agent remaining unclaimed by the holders of
            Debentures for two years after the date upon which the
            principal of or interest on such Debentures shall have
            become due and payable, shall (unless otherwise required by
            mandatory provisions of applicable escheat or abandoned or
            unclaimed property law) be repaid to the Company by the
            Trustee or Paying Agent and such holders shall (unless
            otherwise required by mandatory provisions of applicable
            escheat or abandoned or unclaimed property law) thereafter
            be entitled to look to the Company only for payment thereof;
            provided, however, that, before being required to make any
            such payment to the Company, the Trustee or Paying Agent
            may, at the expense and written direction of the Company,
            cause to be published once, in an Authorized Newspaper, a
            notice that such moneys remain unclaimed and that, after the
            date set forth in said notice, the balance of such moneys
            then unclaimed will be returned to the Company.

                                  -40-



                 Upon the satisfaction and discharge of this Indenture,
            all moneys then held by any Paying Agent other than the
            Trustee hereunder shall, upon demand of the Company, be
            repaid to it and thereupon such paying agent shall be
            released from all further liability with respect to such
            moneys.

                 The Trustee or any Paying Agent shall deliver or pay to
            the Company from time to time upon a request in writing by
            the Company any moneys or U.S. Government Obligations (or
            the principal or interest on such U.S. Government
            Obligations) held by it as provided in Section 6.1 which, in
            the opinion of a nationally recognized firm of independent
            public accountants expressed in a written certification
            thereof to the Trustee, are then in excess of the amount
            thereof which then would have been required to be deposited
            for the purpose for which such money or U.S. Government
            Obligations were deposited or received.

            for specific purposes) as Events of Default with respect to
            Debentures of a particular series, unless it is either
            inapplicable to a particular series or is specifically
            deleted or modified as contemplated by Section 2.2 for the
            Debentures of such series, in addition to any other events
            as may be defined as Events of Default pursuant to Section

                 payment of the principal of or premium, if any, on any

                 shall become due and payable, whether at maturity
                 thereof, by call for redemption, through any mandatory
                 sinking fund, by redemption at the option of the holder
                 of any Debenture pursuant to the terms of such
                 Debenture, by declaration of acceleration or otherwise,
                 whether or not such payment is prohibited by the

                 specifying such Event of Default or failure and
                 requesting that it be remedied and stating that such
                 notice is a notice of an event which, if continued for
                 90 days after such written notice, will become an Event
                 of Default; or

                 shall have happened and shall be continuing and such
                 indebtedness shall have been accelerated so that the
                 same shall be or become due and payable prior to the

                 payable, and such acceleration shall not be contested
                 in good faith by the Company, and such acceleration

                 notice thereof given by certified or registered mail to
                 the Company from the Trustee or to the Company and the
                 Trustee from the holders of not less than 25% in
                 aggregate principal amount of the Debentures then
                 Outstanding of such series hereunder specifying such
                 event of default and requesting that it be remedied and
                 stating that such notice is a notice of an Event of
                 Default; provided, however, that if such event of
                 default under such indenture or instrument shall be
                 remedied or cured by the Company or be waived by the
                 holders of such indebtedness in any manner authorized
                 by such indenture or instrument or shall otherwise
                 cease to exist, 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 either the Trustee or any of
                 the Debentureholders.

                 If one or more Events of Default shall happen and be
            continuing with respect to Debentures then outstanding of
            any series, then, and in each and every such case, either
            the Trustee, by notice in writing to the Company, or the
            holders of not less than 25% in aggregate principal amount
            of the Debentures then Outstanding of such series, by notice
            in writing to the Company and to the Trustee, may declare
            the principal amount (or, if the Debentures of such series
            are Original Issue Discount Debentures, such portion of the
            principal amount as may be specified in the terms of the
            Debentures of such series) of all Debentures of such series
            and/or such other amount or amounts as the Debentures or
            supplemental indenture with respect to such series may
            provide, if not already due and payable, to be immediately
            due and payable; and upon any such declaration all
            Debentures of such series shall become and be immediately
            due and payable, anything in this Indenture or in any of the
            Debentures of such series contained to the contrary
            notwithstanding; provided, however, that payment of
            principal of (and/or such other specified amount), premium,
            if any, and interest on the Debentures of such series shall
            remain subordinated to the extent provided in Article III.
            This provision, however, is subject to the condition that
            if, at any time after the principal of (and/or such other
            specified amount on) the Debentures of such series shall so
            become due and payable, and before any judgment or decree
            for the payment of the moneys due shall have been obtained
            or entered as hereinafter provided, the Company shall pay or
            shall deposit with the Trustee a sum sufficient to pay all
            matured installments of interest upon all the Debentures of
            such series and the principal of (and/or such other
            specified amount) and premium, if any, on any and all
            Debentures of such series which shall have become due
            otherwise than by acceleration, with interest on such
            principal (and/or such other specified amount) and premium,
            if any, and (to the extent that payment of such interest is
            enforceable under applicable law) on any overdue installment
            of interest, at the rate specified in the Debentures of such
            series (or, if no such rate is specified, at the rate borne
            by the Debentures of such series), to the date of such


                                  -43-



            payment or deposit, and the reasonable compensation and
            expenses of the Trustee, and any and all defaults under this
            Indenture with respect to the Debentures or such series,
            other than the nonpayment of principal of (and/or such other
            specified amount) or premium, if any, and accrued interest
            on Debentures of such series which shall have become due by
            acceleration, shall have been remedied, then and in every
            such case the Trustee shall, upon written request or consent
            of the holders of a majority in aggregate principal amount
            of the Debentures then Outstanding of such series delivered
            to the Company and to the Trustee, waive such default and
            its consequences and rescind or annul such declaration and
            its consequences, but no such waiver, rescission or
            annulment shall extend to or affect any subsequent default,
            or impair any right consequent thereon.

                 For all purposes under this Indenture, if the portion
            of the principal amount as may be specified in the terms of
            any Original Issue Discount Debentures shall have been
            accelerated and declared due and payable pursuant to the
            provisions hereof, then, from and after such declaration,
            unless such declaration has been rescinded and annulled,
            payment of such portion of the principal amount thereof,
            together with interest, if any, thereon and all other
            amounts owing thereunder, shall constitute payment in full
            of such Original Issue Discount Debentures.

                 SECTION 7.2  Covenant of Company to pay to Trustee
            whole amount due on default in payment of Principal or
            interest-Trustee may recover judgment for whole amount
            due-application of moneys received by the Trustee.  In case
            the Company shall commit an Event of Default with respect to
            the Debentures of any series described in Section 7.1(a) or
            (b), then upon demand of the Trustee, the Company shall pay
            to the Trustee, for the benefit of the holders of the
            Debentures then Outstanding of such series, the whole amount
            which then shall have become due on all such Debentures of
            such series for principal, premium, if any, and interest,
            with interest on the overdue principal and premium, if any,
            and (to the extent that payment of such interest is
            enforceable under applicable law) upon overdue installments
            of interest, at the rate specified in the Debentures of such
            series (or, if no such rate is specified, at the rate borne
            by the Debentures of such series), and in addition thereto,
            such additional amount as shall be sufficient to cover the
            costs and expenses of collection, including the reasonable
            compensation, expenses, liabilities, disbursements and
            advances of the Trustee, any predecessor Trustee, their
            agents and counsel.  In case the Company shall pay the same
            in accordance with the provisions of this Section 7.2 and,
            prior to such payment neither the Trustee nor the holders of
            the Debentures then Outstanding of such series shall have
            taken any steps to begin enforcing their rights under this
            Indenture and so long as no additional Event of Default with
            respect to the Debentures of such series shall have
            occurred, from and after such payment, the Event of Default
            giving rise to the demand by the Trustee pursuant to this
            Section 7.2 shall be

                                  -44-




            deemed to be no longer continuing and shall be deemed to
            have thereupon been remedied, cured or waived without
            further action upon the part of either the Trustee or any of
            the Debentureholders.  In case the Company shall fail to pay
            the same forthwith upon such demand, the Trustee, in its own
            name and as trustee of an express trust, may institute any
            judicial proceedings at law or in equity for the collection
            of the sums so due and unpaid and may prosecute such
            proceedings to judgment or final decree, and may enforce the
            same against the Company or any other obligor upon the
            Debentures of such series and collect the moneys adjudged or
            decreed to be payable in the manner provided by law out of
            the property of the Company or any other obligor upon the
            Debentures of such series, wherever situated.  The right of
            the Trustee to recover such judgment shall not be affected
            by the exercise of any other right, power or remedy for the
            enforcement of the provisions of this Indenture.

                 In case of the pendency of any receivership,
            insolvency, liquidation, bankruptcy, reorganization,
            arrangement, adjustment, composition or other judicial
            proceeding relative to the Company or any other obligor upon
            the Debentures or the property of the Company or of such
            other obligor or their creditors, the Trustee (irrespective
            of whether the principal of any Debentures shall then be due
            and payable as therein expressed or by declaration of
            acceleration or otherwise and irrespective of whether the
            Trustee shall have made any demand on the Company for the
            payment of overdue principal or interest) shall be entitled
            and empowered to file and prove a claim for the whole amount
            of principal, premium, if any, and interest owing and unpaid
            in respect of the Debentures of any series for which it
            serves as Trustee and to file such other papers or documents
            as may be necessary or advisable in order to have the claims
            of the Trustee (including any claim for the reasonable
            compensation, expenses, disbursements and advances of the
            Trustee, any predecessor Trustee, their agents and counsel)
            and of the Debentureholders of such series allowed in such
            judicial proceeding, and to receive payment of or on account
            of such claims and to distribute the same after the
            deduction of its charges and expenses; and any receiver,
            assignee, trustee, liquidator, sequestrator (or other
            similar official) in any judicial proceeding is hereby
            irrevocably authorized and instructed by each of the
            Debentureholders of such series to make such payments to the
            Trustee, and, in the event that the Trustee shall consent to
            the making of such payments directly to the Debentureholders
            of such series, to pay to the Trustee any amount due it or
            any predecessor Trustee, for compensation and expenses,
            including counsel fees incurred up to the date of such
            distribution. Nothing contained in this Indenture shall be
            deemed to give to the Trustee any right to accept or consent
            to any plan or reorganization, arrangement, adjustment or
            composition affecting the Debentureholders or the rights of
            any Debentureholder, or to authorize the Trustee to vote in
            respect of the claim of any Debentureholder in any such
            proceeding.


                                  -45-



                 Subject to the provisions of Article III, any moneys or
            property received by the Trustee under this Section 7.2
            shall be applied in the following order, at the date or
            dates fixed by the Trustee and, in case of the distribution
            of such moneys or property on account or principal, premium,
            if any, or interest, upon presentation of the several
            Debentures of the series in respect of which such moneys
            were received, and stamping thereon the payment, if only
            partially paid, and upon surrender thereof if fully paid:

                       First:  To the payment of costs and expenses of
                 collections, and reasonable compensation to the
                 Trustee, its agents, attorneys and counsel, and all
                 advances made and expenses and liabilities incurred by
                 the Trustee, except as a result of its negligence or
                 bad faith and all other amounts owing to the Trustee or
                 any predecessor Trustee pursuant to Section 11.2
                 hereof;

                       Second:  In case the principal of the Outstanding
                 Debentures in respect of which such moneys were
                 received shall not have become due and be unpaid, to
                 the payment of interest on such Debentures, in the
                 order of the maturity of the installments of such
                 interest, with interest (so far as may be lawful) upon
                 the overdue installments of interest at the rate
                 specified in such Debentures (or, if no such rate is
                 specified, at the rate borne by the Debentures of such
                 series), such payments to be made ratably to the
                 persons entitled thereto;

                       Third:  In case the principal of the Outstanding
                 Debentures in respect of which such moneys were
                 received and/or such other amount or amounts as the
                 Debentures or supplemental indenture with respect to
                 such series shall provide, shall have become due, by
                 declaration or otherwise, to the payment of the whole
                 amount then owing and unpaid upon such Debentures for
                 principal (and/or such other specified amount),
                 premium, if any, and interest, with interest on the
                 overdue principal (and/or such other specified amount),
                 premium, if any, and (so far as may be lawful) upon
                 overdue installments of interest, at the rate specified
                 in such Debentures (or, if no such rate is specified,
                 at the rate borne by the Debentures of such series),
                 and in case such moneys shall be insufficient to pay in
                 full the whole amount so due and unpaid upon such
                 Debentures, then to the payment of such principal
                 (and/or such other specified amount), premium, if any,
                 and interest, with interest on the overdue principal
                 (and/or such other specified amount), premium, if any,
                 and (so far as may be lawful) upon overdue installments
                 of interest, at the rate specified in such Debentures
                 (or, if no such rate is specified, at the rate borne by
                 the Debentures of such series), without preference or
                 priority of principal (and/or such other specified
                 amount) and premium,

                                  -46-




                 if any, over interest, or of interest over principal
                 (and/or specified amount) and premium, if any, or of
                 any installment of interest over any other installment
                 of interest, or of any such Debenture over any other
                 such Debenture, ratably to the aggregate of such
                 principal (and/or such other specified amount),
                 premium, if any, and accrued and unpaid interest;

                       Fourth:  To the payment of the remainder, if any,
                 to the Company, its successors or assigns, or to
                 whomever may be so lawfully entitled to receive the
                 same, or as a court of competent jurisdiction may
                 direct.

                 SECTION 7.3  Trustee may enforce rights of action
            without possession of Debentures.  All rights of action
            under this Indenture or any of the Debentures Outstanding of
            any series hereunder enforceable by the Trustee may be
            enforced by the Trustee without the possession of any of the
            Debentures or the production thereof at the trial or other
            proceedings relative thereto, and any such suit or
            proceeding instituted by the Trustee shall be brought for
            the ratable benefit of the holders of the Debentures with
            respect to which the rights are being exercised, subject to
            the provisions of this Indenture.

                 SECTION 7.4  Delays or omissions not to impair any
            rights or powers accruing upon default.  No delay or
            omission of the Trustee or of the Debentureholders to
            exercise any rights or powers accruing upon any default
            which shall not have been remedied shall impair any such
            right or power, or shall be construed to be a waiver of any
            such default or acquiescence therein; and every power and
            remedy given by this Article VII to the Trustee and the
            holders of the Debentures of any series may be exercised
            from time to time and as often as may be deemed expedient by
            the Trustee or by the holders of the Debentures of such
            series.

                 SECTION 7.5  In Event of Default Trustee may protect
            and enforce its rights by appropriate proceedings-holders of
            majority in aggregate Principal amount of Debentures of a
            series may waive default.  If any one or more Events of
            Default shall happen and be continuing, the Trustee may, in
            its discretion, proceed to protect and enforce the rights
            vested in it by this Indenture by such appropriate judicial
            proceedings as the Trustee, being advised by its counsel,
            shall deem most effectual to protect and enforce any of said
            rights, either by suit in equity or by action at law or by
            proceeding in bankruptcy or otherwise, whether for the
            specific performance of any covenant or agreement contained
            in this Indenture or in aid of the exercise of any power
            granted in this Indenture, or to enforce any other legal or
            equitable right vested in the Trustee by this Indenture or
            by law.

                 Provided the Debentures of any series shall not then be
            due and payable by reason of a declaration pursuant to
            Section 7.1 hereof, the holders of a majority in aggregate
            principal amount

                                  -47-




            of the Debentures of such series then Outstanding may on
            behalf of the holders of all of the Debentures of such
            series waive by written notice any past default hereunder
            and its consequences, except a default in the payment of
            interest on or principal and premium, if any, of any of the
            Debentures of such series.  In the case of any such waiver,
            the Company, the Trustee and the holders of the Debentures
            of such series shall be restored to their former positions
            and rights hereunder, respectively; but no such waiver shall
            extend to any subsequent or other default or impair any
            right consequent thereon.

                 SECTION 7.6  Holders of majority in aggregate Principal
            amount of Debentures of any series may direct exercise of
            remedies.  The holders of a majority in aggregate principal
            amount of the Debentures then Outstanding of any series
            shall have the right, by an instrument in writing executed
            and delivered to the Trustee, to direct the time, method and
            place of conducting any proceedings for any remedy available
            to the Trustee, or of exercising any power or trust
            conferred upon the Trustee under this Indenture, with
            respect to the Debentures of such series; provided, however,
            that subject to the provisions of Section 11.1 of this
            Indenture, the Trustee shall have the right to decline to
            follow any such direction if the Trustee, being advised by
            counsel, determines that the action or proceedings so
            directed may not lawfully be taken or if the Trustee in good
            faith shall, by Responsible Officers, determine that the
            action or proceedings so directed would involve the Trustee
            in personal liability, or would be unduly prejudicial to the
            holders of the Debentures of such series not joining in such
            direction, and the Trustee may take any other action deemed
            proper by the Trustee which is not inconsistent with such
            direction.

                 SECTION 7.7  Limitation on suits by Debentureholders.
            No holder of any Debenture of any series shall have the
            right to institute any suit, action or proceeding, in equity
            or at law, for the execution of any trust or power hereof,
            or for the enforcement of any other remedy under or upon
            this Indenture or the Debentures of such series, unless the
            holders of a majority in aggregate principal amount of the
            Debentures then Outstanding of such series shall have made
            written request upon the Trustee and shall have afforded to
            it a reasonable opportunity either to proceed to exercise
            the powers hereinbefore granted or to institute such suit,
            action or proceeding in its own name, as Trustee hereunder,
            and shall have offered to the Trustee reasonable indemnity
            against the costs, expenses and liabilities to be incurred
            therein or thereby, and the Trustee shall have refused or
            neglected to comply with such request for 60 days after its
            receipt of such request and no direction inconsistent with
            such request shall have been given to the Trustee pursuant
            to Section 7.6; it being understood and intended that no one
            or more holders of Debentures of any series shall have any
            right under this Indenture or under the Debentures, by his
            or their action, to enforce any right hereunder except in
            the manner

                                  -48-




            herein provided, and that all proceedings hereunder, at law
            or in equity, shall be instituted, had and maintained in the
            manner herein provided and for the ratable benefit of all
            holders of the Debentures of such series. Subject to the
            provisions of Article III, notwithstanding any provision of
            this Indenture to the contrary, the right, which is absolute
            and unconditional, of any Debentureholder to receive the
            payment of the principal of, premium, if any, and interest
            on his Debentures at and after the respective due dates
            (including maturity by call for redemption, through any
            sinking fund, declaration unless annulled pursuant to
            Section 7.1 hereof, or otherwise), of such principal,
            premium, if any, or interest, or the right, which is also
            absolute and unconditional, of any Debentureholder to
            require conversion of his Debentures pursuant to Article
            XIII hereof if the terms of such Debentures provide for
            convertibility pursuant to Section 2.2, or the right to
            institute suit for the enforcement of any such payment at or
            after such due dates or of such right to convert, shall not
            be impaired or affected without the consent of such holder,
            and the obligation of the Company, which is also absolute
            and unconditional, to pay the principal of, premium, if any,
            and interest on each of the Debentures to the respective
            holders thereof at the times and places in the Debentures
            expressed shall not be impaired or affected.

                 Notwithstanding anything to the contrary contained in
            this Section 7.7, the parties to this Indenture and the
            Debentureholders agree as follows:

                 Any court may in its discretion require, in any suit
            for the enforcement of any right or remedy under this
            Indenture, or in any suit against the Trustee for any action
            taken, suffered or omitted by it as Trustee, the filing by
            any party litigant in such suit of an undertaking to pay the
            costs of such suit, and such court may in its discretion
            assess reasonable costs, including reasonable attorneys'
            fees, against any party litigant in such suit, having due
            regard to the merits and good faith of the claims or
            defenses made by such party litigant; provided, however,
            that the provisions of this paragraph shall not apply to any
            suit instituted, directly or through an agent or agents, by
            the Trustee, to any suit instituted by any Debentureholder
            of any series, or group of Debentureholders of any series,
            holding in the aggregate more than 10% in aggregate
            principal amount of the Debentures then Outstanding of such
            series or to any suit instituted by any Debentureholder of
            any series for the enforcement of the payment of the
            principal of, premium, if any, or interest on, any Debenture
            of such series at or after the respective due dates of such
            principal, premium, if any, or interest expressed in his
            Debenture of such series.

                 SECTION 7.8.  No Debentures owned or held by, for the
            account of or for the benefit of the Company to be deemed
            Outstanding for purpose of payment or distribution.  No
            Debentures owned or held by, for the account of or for the
            benefit of the Company or any

                                  -49-




            Affiliate (other than Debentures pledged in good faith which
            would be deemed Outstanding under the provisions of Section
            14.3) shall be deemed Outstanding for the purpose of any
            payment or distribution provided for in this Article VII.

                 SECTION 7.9.  Company and Trustee restored to former
            position on discontinuance or abandonment of proceedings.
            If the Trustee shall have proceeded to enforce any right
            under this Indenture with respect to the Debentures of any
            series, and such proceedings shall have been discontinued or
            abandoned because of waiver, or for any other reason, or
            shall have been determined adversely to the Trustee, then,
            and in any such case, the Company, the Trustee and the
            Debentureholders of such series shall each be restored to
            their former positions and rights hereunder, and all rights,
            remedies and powers of the Trustee shall continue as though
            no such proceeding had been taken.

                              ARTICLE VIII

                 EVIDENCE OF ACTION BY DEBENTUREHOLDERS

                 SECTION 8.1.  Evidence of action by Debentureholders.
            Any demand, request, consent, proxy or other instrument
            which this Indenture may require or permit to be signed and
            executed by the Debentureholders of any series may be in any
            number of concurrent instruments of similar tenor, and may
            be signed or executed by such Debentureholders in person or
            by an attorney duly authorized in writing. Proof of the
            execution of any such demand, request, consent, proxy or
            other instrument, or of a writing appointing any such
            attorney, shall be sufficient for any purpose of this
            Indenture if made in the following manner: the fact and date
            of the execution by any person of such demand, request,
            consent, proxy or other instrument or writing may be proved
            by the certificate of any notary public, or other officer
            authorized to take acknowledgments of deeds to be recorded
            in any state or country, that the person signing such
            request or other instrument or writing acknowledged to him
            the execution thereof, or by an affidavit of a witness of
            such execution.  Where such execution is by an officer of a
            corporation or association or a member of a partnership on
            behalf of such corporation, association or partnership, or
            by a trustee or other fiduciary, such certificate or
            affidavit shall also constitute sufficient proof of his
            authority.  The Trustee may nevertheless in its discretion
            accept such other proof or require further proof of any
            matter referred to in this Section 8.1 as it shall deem
            reasonable.  The ownership of Debentures shall be proved by
            the registry books or by a certificate of the registrar
            thereof.

                 The Trustee shall not be bound to recognize any person
            as a Debentureholder of any series unless and until his
            title to the Debentures of such series held by him is proved
            in the manner in this Article VIII provided.

                                  -50-



                 Any demand, request, direction, waiver, consent, vote
            or other action of the holder of any Debenture shall be
            conclusive and shall bind all future holders of the same
            Debenture and of any Debenture issued in exchange or
            substitution therefor irrespective of whether or not any
            notation in regard thereto is made upon such Debenture.  Any
            such holder, however, may revoke the consent as to his
            Debenture or portion thereof.  Such revocation shall be
            effective only if the Trustee receives the notice of
            revocation before the date the amendment, supplement, waiver
            or other action becomes effective.  An amendment,
            supplement, waiver or other action shall become effective on
            receipt by the Trustee of written consents from the
            Debentureholders of the requisite percentage in aggregate
            principal amount of the Outstanding Debentures of the
            relevant series.  After an amendment, supplement, waiver or
            other action becomes effective, it shall bind every
            Debentureholder of each series of Debentures so affected.

                 The Company or the Trustee, as applicable, may set a
            date for the purpose of determining the Debentureholders
            entitled to consent, vote or take any other action referred
            to in this Section 8.1, which date shall be not less than 10
            days nor more than 60 days prior to the taking of the
            consent, vote or other action.

                               ARTICLE IX

                IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                         OFFICERS AND DIRECTORS

                 SECTION 9.1.  Immunity of incorporators, stockholders,
            officers, directors and employees.  No recourse shall be had
            for the payment of the principal of, premium, if any, or
            interest on any Debenture or for any claim based thereon or
            otherwise in any manner in respect thereof, or in respect of
            this Indenture, to or against any subsidiary, incorporator,
            stockholder, officer, director or employee, as such, past,
            present or future, of the Company or any subsidiary,
            incorporator, stockholder, officer, director or employee, as
            such, past, present or future, of any predecessor or
            successor corporation, either directly or through the
            Company or such predecessor or successor corporation,
            whether by virtue of any constitutional provision or statute
            or rule of law, or by the enforcement of any assessment or
            penalty, or in any other manner, all such liability being
            expressly waived and released by the acceptance of any
            Debenture and as part of the consideration for the issue
            thereof.


                               ARTICLE X

                  MERGER, CONSOLIDATION, SALE OR LEASE

                 SECTION 10.1.  Documents required to be filed with the
            Trustee upon consolidation, merger, sale, transfer or lease -

                                  -51-




            execution or supplemental indentures - acts of successor
            corporation.  Nothing in this Indenture or in the Debentures
            shall prevent any consolidation or merger of the Company
            with or into any other corporation, or any consolidation or
            merger of any other corporation with or into the Company, or
            any sale, transfer or lease of all or substantially all of
            the property and assets of the Company to any other
            corporation lawfully entitled to acquire the same; provided,
            however, and the Company hereby covenants and agrees, that
            any such consolidation, merger, sale, transfer or lease
            shall be upon the condition that (a) the due and punctual
            payment of the principal of, premium, if any, and interest
            on all the Debentures according to their tenor, and the due
            and punctual performance and observance of all the terms,
            covenants and conditions of this Indenture to be kept or
            performed by the Company shall, by an indenture supplemental
            hereto complying with the provisions of Section 12.1,
            executed and delivered to the Trustee, be expressly assumed
            by the corporation (other than the Company) formed by or
            resulting from any such consolidation or merger, or which
            shall have received the transfer or lease of all or
            substantially all of the property and assets of the Company,
            just as fully and effectually as if such successor
            corporation had been an original party hereto; and (b) the
            Company or such successor corporation, as the case may be,
            shall not, immediately after such consolidation, merger,
            sale, transfer or lease be in default in the performance of
            any such covenant or condition. Thereafter, unless otherwise
            specified pursuant to Section 2.2 for the Debentures of any
            series, all obligations of the predecessor corporation under
            the Debentures of such series shall terminate.  In the event
            of any such sale, transfer or lease, the predecessor Company
            may be dissolved, wound up and liquidated at any time
            thereafter.

                 Every such successor corporation, upon executing an
            indenture supplemental hereto as provided in this Section
            10.1 in form satisfactory to the Trustee, shall succeed to
            and be substituted for the Company with the same effect as
            if it had been named herein as the Company; and any order,
            certificate or resolution of the Board or officers of the
            Company provided for in this Indenture may be made by like
            officials of such successor corporation.  Such successor
            corporation may thereupon cause to be signed, either in its
            own name or in the name of the Company, with such suitable
            reference, if any, to such consolidation, merger, sale,
            transfer or lease as may be required by the Trustee, any or
            all of the Debentures which shall not theretofore have been
            signed by the Company and authenticated by the Trustee or
            any Authenticating Agent; and upon the written order of such
            successor corporation in lieu of the Company, signed by the
            President or any Vice President and Treasurer or any
            Assistant Treasurer of such successor corporation, and
            subject to all the terms, conditions and restrictions herein
            prescribed with respect to the authentication and delivery
            of the Debentures, the Trustee or any Authenticating Agent
            shall authenticate and deliver any and all Debentures which
            shall have been previously signed by the

                                  -52-




            proper officers of the Company and delivered to the Trustee
            or any Authenticating Agent for authentication and any of
            such Debentures which such successor corporation shall
            thereafter, in accordance with the provisions of this
            Indenture, cause to be signed and delivered to the Trustee
            or any Authenticating Agent for such purpose.  All
            Debentures of any series so authenticated and delivered
            shall in all respects have the same rank as the Debentures
            of such series theretofore or thereafter authenticated and
            delivered in accordance with the terms of this Indenture.

                 SECTION 10.2.  Trustee may rely upon Opinion of
            Counsel.  The Trustee may receive and shall, subject to the
            provisions of Section 11.1 of this Indenture, be fully
            protected in relying upon an Officers' Certificate and
            Opinion of Counsel as conclusive evidence that any
            supplemental indenture executed under the foregoing Section
            10.1 complies with the foregoing conditions and provisions
            of this Article X.


                               ARTICLE XI

                         CONCERNING THE TRUSTEE

                 SECTION 11.1.  Acceptance of Trust - responsibilities
            of Trustee.  (a) The Trustee, prior to the occurrence of an
            Event of Default and after the curing or waiving of all
            Events of Default which may have occurred, undertakes to
            perform such duties and only such duties as are specifically
            set forth in this Indenture or in the Trust Indenture Act of
            1939, and no implied covenants or conditions shall be read
            into this Indenture against the Trustee.  In case an Event
            of Default with respect to the Debentures of a particular
            series has occurred (but only during the continuance
            thereof), the Trustee shall exercise with respect to the
            Debentures of such series such of the rights and powers
            vested in it by this Indenture, and use the same degree of
            care and skill in their exercise, as a prudent man would
            exercise or use under the circumstances in the conduct of
            his own affairs.

                 The Trustee, upon receipt of all resolutions,
            certificates, statements, opinions, reports, documents,
            orders or other instruments furnished to the Trustee
            pursuant to any provision of this Indenture, shall examine
            them to determine whether they conform to the requirements
            of this Indenture.

                 (b)  No provision of this Indenture shall be construed
            to relieve the Trustee from liability for its own negligent
            action, its own negligent failure to act, or its own willful
            misconduct, except that

                       (i)  prior to the occurrence of an Event of
                 Default with respect to the Debentures of any series
                 hereunder and after the curing or waiving of all Events
                 of Default with respect to the Debentures of such
                 series which may have occurred, the

                                  -53-




                 Trustee shall not be liable with respect to the
                 Debentures of such series except for the performance of
                 such duties as are specifically set forth in this
                 Indenture, and no implied covenants or obligations
                 shall be read into this Indenture against the Trustee,
                 but the duties and obligations of the Trustee with
                 respect to the Debentures of such series, prior to the
                 occurrence of an Event of Default with respect to the
                 Debentures of such series and after the curing or
                 waiving of all Events of Default with respect to the
                 Debentures of such series which may have occurred,
                 shall be determined solely by the express provisions of
                 this Indenture;

                       (ii)  Subject to the limitations contained in
                 subsection (a) of this Section 11.1, prior to the
                 occurrence of an Event of Default with respect to the
                 Debentures of any series hereunder and after the curing
                 or waiving of all events of Default with respect to the
                 Debentures of such series which may have occurred, and
                 in the absence of bad faith on the part of the Trustee,
                 the Trustee may conclusively rely, as to the truth of
                 the statements and the correctness of the opinions
                 expressed herein, upon certificates or opinions
                 conforming to the requirements of this Indenture;

                       (iii)  the Trustee shall not be personally liable
                 for any error of judgment made in good faith by a
                 Responsible Officer or Officers of the Trustee unless
                 it shall be proved that the Trustee was negligent in
                 ascertaining the pertinent facts; and

                       (iv)  the Trustee shall not be personally liable
                 with respect to any action taken, suffered or omitted
                 to be taken by it in good faith in accordance with the
                 direction of the holders of not less than a majority in
                 aggregate principal amount of the Debentures then
                 Outstanding of any series relating to the time, method
                 and place of conducting any proceeding for any remedy
                 available to the Trustee, or exercising any trust or
                 power conferred upon the Trustee, under this Indenture
                 with respect to the Debentures of such series.

                 (c)  Subject to the limitations contained in
            subsections (a) and (b) of this Section 11.1, the recitals
            contained herein and in the Debentures (except in the
            Trustee's certificate of authentication) shall be taken as
            the statements of the Company, and the Trustee assumes no
            responsibility for the correctness of the same.  The Trustee
            makes no representations as to the validity or sufficiency
            of this Indenture or of the Debentures except that the
            Trustee represents that it is duly authorized to execute and
            deliver this Indenture and to perform its obligations
            hereunder.

                 (d)  Subject to the limitations contained in
            subsections (a) and (b) of this Section 11.1:


                                  -54-



                       (i) the Trustee may rely and shall be protected
                 in acting or refraining from acting upon any
                 resolution, certificate, opinion, notice, consent,
                 request, order, appraisal, report, bond or other paper
                 or document believed by it to be genuine and to have
                 been signed or presented by the proper party or
                 parties;

                       (ii) the Trustee may consult with counsel and the
                 advice of such counsel or any Opinion of Counsel shall
                 be full and complete authorization and protection in
                 respect of any action taken, suffered or omitted by it
                 hereunder in good faith and in accordance with such
                 advice or Opinion of Counsel;

                       (iii) whenever in the administration of the
                 trusts of this Indenture, prior to an Event of Default
                 hereunder and after the curing or waiving of all Events
                 of Default which may have occurred, the Trustee shall
                 deem it necessary or desirable that a matter be proved
                 or established prior to taking, suffering or omitting
                 any action hereunder, such matter (unless other
                 evidence in respect thereof be herein specifically
                 prescribed) may be deemed to be conclusively proved and
                 established by an Officers' Certificate delivered to
                 the Trustee, and such certificate shall be full warrant
                 to the Trustee for any action taken, suffered or
                 omitted by it under the provisions of this Indenture
                 upon the faith thereof;

                       (iv)  the Trustee shall be under no obligation to
                 exercise any of the trusts or powers hereof at the
                 request, order or direction of any of the
                 Debentureholders, pursuant to the provisions of this
                 Indenture, unless such Debentureholders shall have
                 offered to the Trustee reasonable indemnity against all
                 the costs, expenses and liabilities which might be
                 incurred therein;

                       (v)  the Trustee shall not be liable for any
                 action taken or omitted to be taken by it in good faith
                 and believed by it to be authorized or within the
                 discretion or power conferred upon it by this
                 Indenture;

                       (vi) prior to the occurrence of an Event of
                 Default with respect to the Debentures of any series
                 hereunder and after the curing or waiving of all Events
                 of Default with respect to the Debentures of such
                 series which may have occurred, the Trustee shall not
                 be bound to make any investigation into the facts or
                 matters stated in any resolution, certificate, opinion,
                 notice, consent, request, order, appraisal, report,
                 bond or other document or instrument concerning such
                 series, unless requested in writing to do so by the
                 holders of not less than a majority in aggregate
                 principal amount of the Debentures then Outstanding of
                 such series; provided, however, that if the payment
                 within a reasonable time to the

                                  -55-




                 Trustee of the costs, expenses or liabilities likely to
                 be incurred by it in the making of such investigation
                 is, in the opinion of the Trustee (subject to the
                 limitations contained in subsections (a) and (b) of
                 this Section 11.1), not reasonably assured to the
                 Trustee by the security afforded to it by the terms of
                 this Indenture, the Trustee may require reasonable
                 indemnity against such expense or liability as a
                 condition to so proceeding; and provided, further, that
                 nothing in this subdivision (d)(vi) shall require the
                 Trustee to give the Debentureholders any notice other
                 than that required by Section 11.3 hereof.  The
                 reasonable expense of every such investigation shall be
                 paid by the Company or, if paid by the Trustee, shall
                 be repaid by the Company upon demand;

                       (vii) the Trustee may execute any of the trusts
                 or powers hereunder or perform any duties hereunder
                 either directly or by or through agents or attorneys
                 and the Trustee shall not be responsible for any
                 misconduct or negligence on the part of any agent or
                 attorney appointed with due care by it hereunder; and

                       (viii) none of the provisions of this Indenture
                 shall require the Trustee to expend or risk its own
                 funds or otherwise incur any personal financial
                 liability in the performance of any of its duties
                 hereunder, or in the exercise of any of its rights or
                 powers, if it shall have reasonable grounds for
                 believing that repayment of such funds or adequate
                 indemnity against such risk or liability is not
                 reasonably assured to it.

                 SECTION 11.2.  Trustee to be entitled to compensation -
            Trustee not to be accountable for application of proceeds -
            moneys held by Trustee to be trust funds.  The Company
            covenants and agrees to pay to the Trustee from time to
            time, and the Trustee shall be entitled to reasonable
            compensation (which shall not be limited by any provision of
            law in regard to the compensation of a trustee of an express
            trust) for services rendered by it in the execution of the
            trusts hereby created, and shall also be entitled to payment
            of reasonable expenses and disbursements actually made or
            incurred hereunder, including the reasonable fees and
            expenses of counsel, accountants and of all persons not
            regularly in its employ, and all taxes which may have been
            assessed against the Trustee as such on any funds on deposit
            with the Trustee.  The Company also agrees to indemnify each
            of the Trustee and any predecessor Trustee for and hold it
            harmless against loss, liability or expense incurred arising
            out of or in connection with the acceptance or
            administration of this trust or performance of its duties
            hereunder, including the cost and expenses of defending
            itself against any claim of liability in the premises,
            except to the extent that such loss, liability or expense is
            incurred due to the negligence or bad faith of the Trustee
            or predecessor Trustee.  If any property other than cash


                                  -56-



            shall at any time be subject to a lien in favor of the
            Debentureholders, the Trustee, if and to the extent
            authorized by a receivership or bankruptcy court of
            competent jurisdiction or by the supplemental instrument
            subjecting such property to such lien, shall be entitled to
            make advances for the purpose of preserving such property or
            of discharging tax liens or other prior liens or
            encumbrances thereon.  The obligations of the Company under
            this Section 11.2 to compensate the Trustee and to
            indemnify, pay or reimburse the Trustee or any predecessor
            Trustee for expenses, disbursements and advances shall
            constitute additional indebtedness hereunder and shall
            survive the satisfaction and discharge or any other
            termination pursuant to any Bankruptcy Law hereof.  Such
            additional indebtedness shall be secured by a lien prior to
            that of the Debentures of all series with respect to which
            the Trustee acts as Trustee upon all property and funds held
            or collected by the Trustee as such, except funds held in
            trust for the benefit of the holders of particular
            Debentures.

                 The Trustee shall not be accountable for the use or
            application by the Company of any Debentures authenticated
            and delivered hereunder or of the proceeds of such
            Debentures, or for the use or application of any moneys paid
            over by the Trustee in accordance with any provision of this
            Indenture, or for the use or application of any moneys
            received by any paying agent.

                 All moneys received by the Trustee in trust under or
            pursuant to any provision of this Indenture shall constitute
            trust funds for the purposes for which they were paid or
            were held, but need not be segregated in any manner from any
            other moneys and may be deposited by the Trustee, under such
            conditions as may be prescribed by law, in its general
            banking department, and the Trustee shall not be liable for
            any interest thereon, except as otherwise agreed with the
            Company.

                 The parties hereto, and the Debentureholders by their
            acceptance of their Debentures, hereby agree, that when the
            Trustee incurs expenses and renders services after an Event
            of Default occurs, such expenses and the compensation for
            such services are intended by the holders of the Debentures
            and Company to constitute expenses of administration under
            any Bankruptcy Law.

                 SECTION 11.3.  Trustee to give Debentureholders notice
            of default.  The Trustee shall give to the Debentureholders
            of any series notice of the happening of all defaults with
            respect to the Debentures of such series known to it, within
            90 days after the occurrence thereof unless such defaults
            shall have been cured before the giving of such notice;
            provided, however, that, except in the case of a default
            resulting from the failure to make any payment of principal
            of, premium, if any, or interest on the Debentures of any
            series, or in the payment of any mandatory sinking fund
            installment with respect to the Debentures of such

                                  -57-




            series, the Trustee may withhold the giving of such notice
            if and so long as the board of directors, the executive
            committee or a trust committee of directors and/or
            Responsible Officers of the Trustee in good faith determine
            that the withholding of such notice is in the interest of
            the Debentureholders of such series.  For the purpose of
            this Section 11.3, the term "default" means any event which
            is, or after notice or lapse of time or both would become,
            an Event of Default.  Such notice shall be given to the
            Debentureholders of such series in the manner and to the
            extent provided in subsection (c) of Section 11.10.

                 SECTION 11.4.  Trustee acquiring conflicting interest
            must eliminate it or resign.  Reference is made to Section
            310(b) of the Trust Indenture Act of 1934, as amended,
            and with respect to the Debentures of each series, the Trustee
            shall comply therewith. To the extent permitted under 
            Section 310(b)(1) thereof, the Trustee shall not be deemed
            to have a conflicting interest by virtue of being a
            trustee under this Indenture with respect to Debentures 
            of more than one series.

                 SECTION 11.5.  Eligibility of Trustee.  There shall at
            all times be a corporate Trustee under this Indenture which
            shall be a bank or trust company organized and doing
            business under the laws of the United States or of any State
            or the District of Columbia and having a combined capital
            and surplus of not less than $50,000,000 which is authorized
            under the laws of its jurisdiction of incorporation to
            exercise corporate trust powers and is subject to
            supervision or examination by Federal, State or District of
            Columbia authority and which has an office or agency in
            .  If the Trustee publishes reports of conditions at least
            annually, pursuant to law or to the requirements of the
            aforesaid supervising or examining authority, the combined
            capital of the Trustee shall be deemed to be its combined
            capital and surplus as set forth in its most recent report
            of condition so published.  If the Trustee shall at any time
            cease to meet the foregoing standards of eligibility, then
            such Trustee shall resign immediately in the manner and with
            the effect specified in Section 11.6.

                 SECTION 11.6.  Resignation or removal of Trustee.

                 (a) Subject to the limitations contained in subsection
            (d) of this Section 11.6, the Trustee may resign and be
            discharged from the trust hereby created with respect to the
            Debentures of one or more series by giving notice thereof to
            the Company and by giving notice thereof to the
            Debentureholders of such series, in the manner and to the
            extent provided in subsection (c) of Section 11.10. Upon
            receiving such notice of resignation, the Company shall
            promptly appoint a successor trustee or trustees (it being
            understood that any such successor trustee may be appointed
            with respect to the Debentures of one or more or all of such
            series with respect to which the resigning trustee has
            resigned and that at any time there shall be only one
            trustee with respect to the Debentures of any particular
            series) by written instrument, in duplicate, executed by
            order of the Board of Directors, one copy

                                  -58-




            of which instrument shall be delivered to the resigning
            trustee and one copy to the successor trustee.  If no
            successor trustee shall have been so appointed and have
            accepted appointment within 60 days after the mailing of
            such notice of resignation, the resigning trustee may
            petition any court of competent jurisdiction for the
            appointment of a successor trustee, or any Debentureholder
            of such series who has been a bona fide holder of a
            Debenture or Debentures of such series for at least six
            months may on behalf of himself and all others similarly
            situated, petition any such court for the appointment of a
            successor trustee.  Such court may thereupon, after such
            notice, if any, as it may deem proper and prescribe, appoint
            a successor trustee.

                       (b) In case at any time any of the following
                       shall occur-

                       (1) the Trustee shall fail to comply with the
                 provisions of Section 11.4 with respect to the
                 Debentures of any series after written request therefor
                 by the Company or by any Debentureholder of such series
                 who has been a bona fide holder of a Debenture or
                 Debentures of such series for at least six months; or

                       (2) the Trustee shall cease to be eligible in
                 accordance with the provisions of Section 11.5 with
                 respect to the Debentures of any series and shall fail
                 to resign after written request therefor by the Company
                 or by any such Debentureholder; or

                       (3) the Trustee shall become incapable of acting,
                 or shall be adjudged a bankrupt or insolvent, or a
                 receiver of the Trustee or of its property shall be
                 appointed, or any public officer shall take charge or
                 control of the Trustee or of its property or affairs

            then, in such case, the Company may remove the Trustee with
            respect to all Debentures of such series and appoint a duly
            qualified successor trustee by written instrument, in
            duplicate, executed by order of the Board of Directors of
            the Company, one copy of which instrument shall be delivered
            to the Trustee so removed and one copy to the successor
            trustee so appointed, or, subject to the provisions of
            Section 7.7, any Debentureholder who has been a bona fide
            holder of a Debenture or Debentures of such series for at
            least six months may, on behalf of himself and all others
            similarly situated, petition any court of competent
            jurisdiction for the removal of the Trustee with respect to
            all Debentures of such series and the appointment of a
            successor trustee.  Such court may thereupon after such
            notice, if any, as it may deem proper and prescribe, remove
            the Trustee and appoint a duly qualified successor trustee
            with respect to the Debentures of such series.

                 (c) The holders of a majority in aggregate principal
            amount of the Debentures then Outstanding of any series may
            at any time

                                  -59-




            remove the Trustee and appoint a duly qualified successor
            trustee with respect to such series by delivery to the
            Trustee so removed, to the successor trustee and to the
            Company of the evidence provided for in Section 8.1 of the
            action in that regard taken by Debentureholders.

                 (d) Any resignation or removal of the Trustee and any
            appointment of a duly qualified successor trustee pursuant
            to any of the provisions of this Section shall become
            effective upon acceptance of appointment by the successor
            trustee as provided in Section 11.7.

                 SECTION 11.7.  Acceptance by successor Trustee.

                 (a)   In case of the appointment hereunder of a
            successor trustee with respect to all Debentures, every duly
            qualified successor trustee so appointed under any of the
            methods herein provided shall execute, acknowledge and
            deliver to its predecessor trustee and to the Company an
            instrument in writing accepting such appointment hereunder
            and thereupon such successor trustee, without any further
            act, deed or conveyance, shall become fully vested with the
            rights, powers, trusts, duties and obligations of its
            predecessor in the trust hereunder with like effect as if
            originally named as Trustee herein.  The predecessor trustee
            shall, nevertheless, at the written request of the successor
            trustee, pay over to the successor trustee all moneys at the
            time held by it herein; and the Company and the predecessor
            trustee upon payment or provision therefor of any amounts
            then due the predecessor trustee pursuant to the provisions
            of Section 11.2, shall execute and deliver such instruments
            and do such other things as may reasonably be required for
            more fully and certainly vesting and confirming in the
            successor trustee all such rights, powers, trusts, duties
            and obligations.  The Company shall promptly give notice of
            the appointment of such successor trustee to the
            Debentureholders in the manner and to the extent provided in
            subsection (c) of Section 11.10.

                 (b)  In the case of the appointment hereunder of a
            successor trustee with respect to the Debentures of one or
            more (but not all) series, the Company, the predecessor
            trustee and each successor trustee with respect to the
            Debentures of such series shall execute and deliver an
            indenture supplemental hereto wherein each successor trustee
            shall accept such appointment and which (i) shall contain
            such provisions as shall be necessary or desirable to
            transfer and confirm to, and to vest in, each successor
            trustee all the rights, powers, trusts and duties of the
            predecessor trustee with respect to the Debentures of such
            series to which the appointment of such successor trustee
            relates, (ii) if the predecessor trustee is not retiring
            with respect to all Debentures of such series, shall contain
            such provisions as shall be deemed necessary or desirable to
            confirm that all the rights, powers, trusts and duties of
            the predecessor

                                  -60-




            trustee with respect to the Debentures of such series as to
            which the predecessor trustee is not retiring shall continue
            to be vested in the predecessor trustee, and (iii) shall add
            to or change any of the provisions of this Indenture as
            shall be necessary to provide for or facilitate the
            administration of the trusts hereunder by more than one
            Trustee, it being understood that nothing herein or in such
            supplemental indenture shall constitute such Trustees
            co-trustees of the same trust and that each such Trustee
            shall be trustee of a trust or trusts hereunder separate and
            apart from any trust or trusts hereunder administered by any
            other such Trustee; and upon the execution and delivery of
            such supplemental indenture the resignation or removal of
            the predecessor trustee shall become effective to the extent
            provided therein and each such successor trustee, without
            any further act, deed or conveyance, shall become vested
            with all the rights, powers, trusts and duties of the
            predecessor trustee with respect to the Debentures of such
            series to which the appointment of such successor trustee
            relates; but, on request of the Company or any successor
            trustee, such predecessor trustee upon payment of its
            charges shall duly assign, transfer and deliver to such
            successor trustee all property and money held by such
            predecessor trustee hereunder with respect to the Debentures
            of such series to which the appointment of such successor
            trustee relates.  Upon request of any such successor
            trustee, the Company shall execute any and all instruments
            for more fully and certainly vesting in and confirming to
            such successor trustee all such rights, powers and trusts
            referred to in this subsection (b) of this Section.

                 SECTION 11.8.  Successor to Trustee by merger or
            consolidation, etc.  Any corporation or national banking
            association into which the Trustee may be merged, or with
            which it may be consolidated, or to which the Trustee
            transfers all or substantially all of its corporate trust
            assets, or any corporation or national banking association
            resulting from any merger or consolidation or conversion to
            which the Trustee shall be a party, shall be the successor
            trustee under this Indenture without the execution or filing
            of any instruments or any further act on the part of any of
            the parties hereto.

                 In case at the time such successor trustee shall
            succeed to the trusts created by this Indenture any of the
            Debentures shall have been authenticated but not delivered,
            any such successor trustee may adopt the certificate of
            authentication of its predecessor trustee, and deliver such
            Debentures so authenticated; and in case at that time any of
            the Debentures shall not have been authenticated, any
            successor trustee may authenticate such Debentures either in
            the name of any predecessor hereunder or in the name of the
            successor trustee; and in all such cases such certificates
            shall have the full force which it is anywhere in the
            Debentures or in this Indenture provided that the
            certificate of authentication of the Trustee shall have;
            provided, however, that the right to adopt the

                                  -61-



            certificate of authentication of any predecessor trustee or
            authenticate Debentures in the name of any predecessor
            trustee shall apply only to its successor or successors by
            merger, conversion or consolidation.

                 SECTION 11.9.  Limitations on right of Trustee as a
            creditor to obtain payment of certain claims.  Reference is
            made to Section 311 of the Trust Indenture Act of 1939, as
            amended, for purposes of which the following terms shall
            have the following meanings:

                 checks or other orders drawn upon banks or bankers and
                 payable upon demand; and

                       (ii) the term "self-liquidating paper" shall mean
                 any draft, bill of exchange, acceptance or obligation

                 processing, manufacturing, shipment, storage or sale of
                 goods, wares or merchandise and which is secured by
                 documents evidencing title to, possession of, or a lien
                 upon, the goods, wares or merchandise or the
                 receivables or proceeds arising from the sale of the
                 goods, wares or merchandise previously constituting the
                 security, provided the security is received by the
                 Trustee simultaneously with the creation of the
                 creditor relationship with the Company arising from the
                 making, drawing, negotiating or incurring of the draft,
                 bill of exchange, acceptance or obligation.

                 SECTION 11.10.  Trustee to make annual report to
            Debentureholders - Trustee to make other reports to
            Debentureholders - Debentureholders to whom reports to be
            transmitted.

                 (a) The Trustee shall, so long as any Debentures are
            Outstanding of any series with respect to which it acts as
            Trustee, transmit to the Debentureholders of such series,
            within 60 days after              of each year beginning
            with the year     , a brief report as of such
            that complies with Section 313(a) of the Trust Indenture Act
            of 1939, as amended, to the extent any such report is
            required pursuant to such Section.

                 (b) The Trustee shall, so long as any Debentures of any
            series with respect to which it acts as Trustee shall be
            Outstanding, also transmit to the Debentureholders of such
            series, as hereinafter provided, within the times
            hereinafter specified, a brief report with respect to the
            character and amount of any advances (and if the Trustee
            elects so to state the circumstances surrounding the making
            thereof) made by the

                                  -62-




            Trustee, as such, since the date of the last report
            transmitted pursuant to the provisions of subsection (a) of
            this Section 11.10 (or if no such report has been so
            transmitted, since the date of the execution of this
            Indenture), for the reimbursement of which it claims or may
            claim a lien or charge prior to that of the Debentures of
            such series, on property or funds held or collected by the
            Trustee, as such, and which it has not previously reported
            pursuant to this subsection (b), if such advances remaining
            unpaid at any time aggregate more than 10% of the principal
            amount of the Debentures of such series then Outstanding,
            such report to be so transmitted within 90 days after such
            time.

                 (c) All reports required by this Section 11.10, and all
            other reports or notices which are required by any other
            provision of this Indenture to be transmitted in accordance
            with the provisions of this Section 11.10, shall be
            transmitted by mail; (i) to all registered holders of
            Debentures of such series, as the names and addresses of
            such holders appear upon the Debenture register; (ii) to
            such holders of Debentures of such series as have, within
            the two years preceding such transmission, filed their names
            and addresses with the Trustee for that purpose; and (iii)
            except in the case of reports pursuant to subsection (b) of
            this Section 11.10, to all holders of Debentures of such
            series whose names and addresses have been furnished to or
            received by the Trustee pursuant to Section 4.6(d).

                 (d) The Trustee shall, at the time of the transmission
            to the Debentureholders of any report or notice pursuant to
            this Section 11.10, file a copy thereof with the Securities
            and Exchange Commission.  The Company will notify the
            Trustee if and when the Debentures of any series become
            listed on any stock exchange and the Trustee will thereafter
            file a copy of any such report or notice with such stock
            exchange.

                 SECTION 11.11.  Preservation of information by Trustee
            - Trustee to give certain information to Debentureholders
            upon application.  The Trustee shall preserve, in as current
            a form as is reasonably practicable, all information
            furnished it pursuant to subsection (d) of Section 4.6
            hereof or received by it as Debenture registrar hereunder.
            The Trustee may destroy such information upon receipt of new
            information updating information previously furnished.

                 Within five Business days after receipt by the Trustee
            of a written application by any three or more
            Debentureholders stating that the applicants desire to
            communicate with other Debentureholders with respect to
            their rights under this Indenture or under the Debentures,
            and accompanied by a copy of the form of proxy or other
            communication which such applicants propose to transmit, and
            by reasonable proof that each such applicant has owned a
            Debenture or Debentures for a period of at least six months
            preceding such application, the Trustee shall,

                                  -63-




            at its election, either (a) afford to such applicants access
            to all information so furnished to or received by the
            Trustee and not destroyed pursuant to the provisions of this
            Section 11.11, or (b) inform such applicants as to the
            approximate number of Debentureholders according to the most
            recent information so furnished to or received by the
            Trustee, and as to the approximate cost of mailing to the
            Debentureholders the form of proxy or other communication,
            if any, specified in such application.  If the Trustee shall
            elect not to afford to such applicants access to such
            information, the Trustee shall, upon the written request of
            such applicants, mail to all Debentureholders whose names
            and addresses are contained in the then current information
            filed with the Trustee as aforesaid copies of the form of
            proxy or other communication which is specified in such
            request, with reasonable promptness after a tender to the
            Trustee of the material to be mailed and the payment, or
            provision for the payment, of the reasonable expenses of
            such mailing, unless within five business days after such
            tender, the Trustee shall mail to such applicants, and file
            with the Securities and Exchange Commission, together with a
            copy of the material to be mailed, a written statement to
            the effect that, in the opinion of the Trustee, such mailing
            would be contrary to the best interests of the
            Debentureholders or would be in violation of applicable law.
            Such written statement shall specify the basis of such
            opinion.  If the Securities and Exchange Commission, after
            granting opportunity for a hearing upon the objections
            specified in said written statement and on notice to the
            Trustee, shall enter an order refusing to sustain any of
            such objections, or, if, after the entry of an order
            sustaining one or more of such objections, the Securities
            and Exchange Commission shall find, after notice and
            opportunity for a hearing, that all objections sustained
            have been met and shall enter an order so declaring, the
            Trustee shall mail copies of such material to all such
            Debentureholders with reasonable promptness after such
            determination and the renewal of the aforesaid tender;
            otherwise the Trustee shall be relieved of any obligation or
            duty to such applicants respecting their application.

                 Neither the Company, the Trustee nor any person acting
            as Debenture registrar or paying agent shall be liable or
            accountable to the Company or to any Debentureholder by
            reason of the disclosure of any such information as to the
            names and addresses of Debentureholders in accordance with
            the provisions of this Section 11.11, regardless of the
            source from which such information was derived, nor by
            reason of the mailing of any material pursuant to a request
            made under this Section 11.11.

                 SECTION 11.12.  Trustee may hold Debentures and
            otherwise deal with Company.  The Trustee, the Debenture
            registrar, any paying agent or any other agent of the
            Company in its individual or any other capacity may buy,
            own, hold and sell any of the Debentures or any other
            evidences of indebtedness or other


                                  -64-



            securities, whether heretofore or hereafter created or
            issued, of the Company or any subsidiary or Affiliate with
            the same rights it would have it if were not Trustee,
            Debenture registrar, paying agent or such other agent; and
            subject to the provisions of this Article XI, the Trustee
            may engage or be interested in any financial or other
            transaction with the Company or any subsidiary or Affiliate,
            including without limitation, secured and unsecured loans to
            the Company or any subsidiary or Affiliate; and may maintain
            any and all other general banking and business relations
            with the Company and any subsidiary or Affiliate with like
            effect and in the same manner and to the same extent as if
            the Trustee were not a party to this Indenture; and no
            implied covenant shall be read into this Indenture against
            the Trustee in respect of any such matters.

                 SECTION 11.13.  Trustee may comply with any rule,
            regulation or order of the Securities and Exchange
            Commission.  The Trustee may comply in good faith with any
            rule, regulation or order of the Securities and Exchange
            Commission made pursuant to the terms and provisions of the
            Trust Indenture Act of 1939 and shall be fully protected in
            so doing notwithstanding that such rule, regulation or order
            may thereafter be amended or rescinded or determined by
            judicial or other authority to be invalid for any reason,
            but nothing herein contained shall require the Trustee to
            take any action or omit to take any action in accordance
            with such rule, regulation or order, except as is in this
            Indenture otherwise required.

                 SECTION 11.14.  Appointment of Authenticating Agent.
            The Trustee may appoint an Authenticating Agent or Agents
            with respect to one or more series of Debentures which shall
            be authorized to act on behalf of the Trustee to
            authenticate Debentures of such series upon exchange,
            registration of transfer or partial redemption or partial
            conversion thereof or pursuant to Section 2.9, and if the
            Trustee is required to appoint one or more Authenticating
            Agents with respect to any series of Debentures, to
            authenticate Debentures of such series and to take such
            other actions as are specified in Sections 2.4, 2.8, 2.11,
            5.2 and 13.3 and Debentures so authenticated shall be
            entitled to the benefits of this Indenture and shall be
            valid and obligatory for all purposes as if authenticated by
            the Trustee hereunder.  Whenever reference is made in this
            Indenture to the authentication and delivery of Debentures
            by the Trustee or the Trustee's certificate of
            authentication, such reference shall be deemed to include
            authentication and delivery on behalf of the Trustee by an
            Authenticating Agent and a certificate of authentication
            executed on behalf of the Trustee by an Authenticating Agent
            (except in respect to an original issue). Each
            Authenticating Agent shall be acceptable to the Company and
            shall at all times be a corporation organized and doing
            business under the laws of the United States of America, any
            State thereof or the District of Columbia, authorized under
            such laws to act as Authenticating Agent, having a combined
            capital and surplus of

                                  -65-




            not less than $1,000,000 and subject to supervision or
            examination by Federal or State authority. If such
            Authenticating Agent publishes reports of condition at least
            annually, pursuant to law or to the requirements of said
            supervising or examining authority, then for the purposes of
            this Section 11.14, the combined capital and surplus of such
            Authenticating Agent shall be deemed to be its combined
            capital and surplus as set forth in its most recent report
            of condition so published.  If at any time an Authenticating
            Agent shall cease to be eligible in accordance with the
            provisions of this Section 11.14, such Authenticating Agent
            shall resign immediately in the manner and with the effect
            specified in this Section 11.14.

                 Any corporation into which an Authenticating Agent may
            be merged or converted or with which it may be consolidated,
            or any corporation resulting from any merger, conversion or
            consolidation to which such Authenticating Agent shall be a
            party, or any corporation succeeding to the corporate agency
            or corporate trust business of such Authenticating Agent,
            shall continue to be an Authenticating Agent, provided such
            corporation shall be otherwise eligible under this Section
            11.14, without the execution or filing of any paper or any
            further act on the part of the Trustee or such
            Authenticating Agent.

                 An Authenticating Agent may resign at any time by
            giving written notice thereof to the Trustee and to the
            Company.  The Trustee may at any time terminate the agency
            of an Authenticating Agent by giving written notice thereof
            to such Authenticating Agent and to the Company.  Upon
            receiving such a notice or resignation or upon such a
            termination, or in case at any time such Authenticating
            Agent shall cease to be eligible in accordance with the
            provisions of this Section 11.14, the Trustee may appoint a
            successor Authenticating Agent which shall be acceptable to
            the Company and shall provide notice to the holders of the
            Debentures of the series as to which the Authenticating
            Agent will serve as provided in Section 14.9.  Any successor
            Authenticating Agent upon acceptance of its appointment
            hereunder shall become vested with all the rights, powers
            and duties of its predecessor hereunder, with like effect as
            if originally named as an Authenticating Agent.  No
            successor Authenticating Agent shall be appointed unless
            eligible under the provisions of this Section 11.14.

                 The Trustee agrees to pay each Authenticating Agent
            from time to time reasonable compensation for its services
            under this Section, and the Trustee shall be entitled to be
            reimbursed for such payments, subject to the provisions of
            Section 11.2.

                 If an appointment with respect to one or more series is
            made pursuant to this Section 11.14, the Debentures of such
            series may have endorsed thereon, in addition to the
            Trustee's certificate of authentication, as alternative
            certificate of authentication in the following form:

                                  -66-




                 This is one of the Debentures of the series designated
            therein referred to in the within-mentioned Indenture.


                                                              , As Trustee

                                         By
                                               As Authenticating Agent

                                         By
                                                   Authorized Officer

                 If all of the Debentures of a series may not be
            originally issued at one time, and if the Trustee does not
            have an office capable of authenticating Debentures upon
            original issuance located where the Company wishes to have
            Debentures of such series authenticated upon original
            issuance, the Trustee, if so requested by the Company in
            writing (which writing need not comply with Section 14.8 and
            need not be accompanied by an Opinion of Counsel), shall
            appoint in accordance with this Section 11.14 an
            Authenticating Agent having an office in a place designated
            by the Company with respect to such series of Debentures.

                              ARTICLE XII

                        SUPPLEMENTAL INDENTURES

                 SECTION 12.1.  Company and Trustee may enter into
            supplemental indenture for special purposes.  Without the
            consent of any of the Debentureholders, the Company, when
            authorized by resolution of its Board of Directors, and the
            Trustee from time to time and at any time, subject to the
            conditions and restrictions in this Indenture contained, may
            enter into an indenture or indentures supplemental hereto in
            form satisfactory to the Trustee, which thereafter shall
            form a part hereof, for any one or more of the following
            purposes:

                       (a) to add to the covenants and agreements of the
                 Company in this Indenture contained, other covenants
                 and agreements thereafter to be observed for the
                 benefit of the Holders of all or any series of
                 Debentures (and if such covenants and agreements are to
                 be for the benefit of less than all series of
                 Debentures, stating that such covenants and agreements
                 are expressly being included solely for the benefit of
                 such series) or to surrender any right or power herein
                 reserved to or conferred upon the Company; or

                       (b) to cure any ambiguity or to cure, correct or
                 supplement any defect or inconsistent provision
                 contained in this Indenture or in any supplemental
                 indenture; or

                                  -67-



                       (c) to make sure provisions in regard to matters
                 or questions arising under this Indenture which may be
                 necessary or desirable, or otherwise change this
                 Indenture in any manner, which shall not adversely
                 affect the interests of the Debentureholders of any
                 series; or

                       (d) to evidence the succession of another
                 corporation to the Company, or successive successions,
                 and the assumption by the successor corporation of the
                 covenants, agreements and obligations of the Company
                 pursuant to Article X and to provide for the adjustment
                 of conversion rights pursuant to Section 13.7; or

                       (e) to establish the form or terms of the
                 Debentures of any series as permitted by Sections 2.1
                 and 2.2; or

                       (f) to change or eliminate any of the provisions
                 of this Indenture, provided that, except as otherwise
                 contemplated by Section 2.2(23), any such change or
                 elimination shall become effective only when there is
                 no Debenture outstanding of any series created prior
                 thereto which is entitled to the benefit of such
                 provision; or

                       (g) to add or change any of the provisions of
                 this Indenture to such extent as shall be necessary to
                 permit or facilitate the issuance of Debentures in
                 bearer form, registrable or not registrable as to
                 principal, and with or without interest coupons, or to
                 provide for uncertificated Debentures in addition to
                 certificated Debentures (so long as any
                 "registration-required obligation" within the meaning
                 of Section 163(f)(2) of the Code is in registered form
                 for purposes of the Code); or

                       (h) to amend or supplement any provision
                 contained herein, which was required to be contained
                 herein in order for this Indenture to be qualified
                 under the Trust Indenture Act of 1939, if the Trust
                 Indenture Act of 1939 or regulations thereunder change
                 what is so required to be included in qualified
                 indentures, in any manner not inconsistent with what
                 then may be required for such qualification; or

                       (i) to add any additional Events of Default (and
                 if such Events of Default are to be applicable to less
                 than all series of Securities, stating that such Events
                 of Default are expressly being included solely to be
                 applicable to such series); or

                       (j) to convey, transfer, assign, mortgage or
                 pledge to the Trustee as security for the Debentures of
                 one or more series any property or assets; or

                                  -68-



                       (k) to add to or change any of the provisions of
                 this Indenture as contemplated in Section 11.7(b)

            and the Company hereby covenants that it will fully perform
            all the requirements of any such supplemental indenture
            which may be in effect from time to time. Nothing in this
            Article XII contained shall affect or limit the right or
            obligation of the Company to execute and deliver to the
            Trustee any instrument of further assurance or other
            instrument which elsewhere in this Indenture it is provided
            shall be delivered to the Trustee.

                 The Trustee shall join with the Company in the
            execution of any such supplemental indenture, make any
            further appropriate agreements and stipulations which may be
            therein contained and accept the conveyance, transfer,
            assignment, mortgage or pledge of any property thereunder,
            but the Trustee shall not be obligated to enter into any
            such supplemental indenture which adversely affects the
            Trustee's own rights, duties or immunities under this
            Indenture or otherwise.

                 Any supplemental indenture authorized by the provisions
            of this Section 12.1 may be executed by the Company and the
            Trustee without the consent of the holders of any of the
            Debentures at the time Outstanding, notwithstanding any of
            the provisions of Section 12.2.

                 SECTION 12.2.  Modification of Indenture with consent
            of Debentureholders. With the consent (evidenced as provided
            in Section 8.1) of the holders of not less than 66 2/3% in
            aggregate principal amount of the Debentures at the time
            Outstanding of each series affected by such supplement, the
            Company, when authorized by a resolution of its Board of
            Directors, and the Trustee may from time to time and at any
            time enter into an indenture or indentures supplemental
            hereto for the purpose of adding any provision to or
            changing in any manner or eliminating any of the provisions
            of this Indenture or of any supplemental indenture or of
            modifying in any manner the rights of the holders of such
            series of the Debentures; provided, however, that no such
            supplemental indenture shall (i) extend the time or times of
            payment of the principal of, premium, if any, or the
            interest on, any Debenture, or reduce the principal amount
            of, premium, if any, or the rate of interest on, any
            Debenture (and/or such other amount or amounts as any
            Debentures or supplemental indentures with respect thereto
            may provide to be due and payable upon declaration of
            acceleration of the maturity thereof pursuant to Section
            7.1) or change the currency of payment of principal of,
            premium, if any, or interest on, any Debenture or reduce any
            amount payable on redemption thereof or alter or impair the
            right to convert the same at the rate and upon the terms
            provided in the Indenture or alter or impair the right to
            require redemption at the option of the holder, without the
            consent of the holder of

                                  -69-




            each Debenture so affected, or (ii) reduce the percentage of
            Debentures of any series, the vote or consent of the holders
            of which is required for such modifications and alterations,
            without the consent of the holders of all Debentures then
            Outstanding of such series under the Indenture.
            Notwithstanding the foregoing, no consent of the
            Debentureholders shall be necessary to permit the execution
            of supplemental indentures pursuant to Section 13.7.

                 Upon the request of the Company, accompanied by a copy
            of a resolution of its Board of Directors certified by the
            Secretary or an Assistant Secretary of the Company
            authorizing the execution of any such supplemental
            indenture, and upon the filing with the Trustee of evidence
            of the consent of Debentureholders as aforesaid, the Trustee
            shall join with the Company in the execution of such
            supplemental indenture unless such supplemental indenture
            affects the Trustee's own rights, duties or immunities under
            this Indenture or otherwise, in which case the Trustee may,
            in its discretion, but shall not be obligated, to enter into
            such supplemental indenture.

                 It shall not be necessary for the consent of the
            Debentureholders under this Section 12.2 to approve the
            particular form of any proposed supplemental indenture, but
            it shall be sufficient if such consent shall approve the
            substance thereof.

                 A supplemental indenture which changes or eliminates
            any provision of this Indenture which has expressly been
            included solely for the benefit of one or more particular
            series of Debentures, or which modifies the rights of the
            holders of Debentures of such series with respect to such
            provision, shall be deemed not to affect the rights under
            this Indenture of the holders of Debentures of any other
            series.

                 SECTION 12.3.  Effect of supplemental indentures.  Upon
            the execution of any supplemental indenture pursuant to the
            provisions of this Article XII, this Indenture shall be and
            be deemed to be modified and amended in accordance therewith
            and the respective rights, limitations of rights,
            obligations, duties and immunities under this Indenture of
            the Trustee, the Company and the holders of Debentures shall
            thereafter be determined, exercised and enforced hereunder
            subject in all respects to such modifications and
            amendments, and all the terms and conditions of any such
            supplemental indenture shall be and be deemed to be part of
            the terms and conditions of this Indenture for any and all
            purposes.

                 The Trustee, subject to the provisions of Section 11.1
            may receive an Opinion of Counsel as conclusive evidence
            that any such supplemental indenture complies with the
            provisions of this Article XII.


                                  -70-



                 SECTION 12.4.  Supplemental indentures to conform to
            Trust Indenture Act. Any supplemental indenture executed and
            delivered pursuant to the provisions of this Article XII
            shall conform in all respects to the requirements of the
            Trust Indenture Act of 1939, as amended, as then in effect.

                 SECTION 12.5.  Notation on or exchange of Debentures.
            If an amendment, supplement or waiver changes the terms of a
            Debenture of any series, the Trustee may require the Holder
            of the Debenture to deliver it to the Trustee.  The Trustee
            may place an appropriate notation on the Debenture about the
            changed terms and return it to the Holder.  Alternatively,
            if the Company or the Trustee so determines, the Company in
            exchange for the Debenture of any series shall issue and the
            Trustee shall authenticate a new Debenture of such series
            that reflects the changed terms.

                              ARTICLE XIII

                        CONVERSION OF DEBENTURES

                 SECTION 13.1.     Applicability of Article.  Debentures
            of any series which are convertible into Capital Stock at
            the option of the Debentureholder shall be convertible in
            accordance with their terms and (unless otherwise specified
            as contemplated by Section 2.2. for Debentures of any
            series) in accordance with this Article.  Each reference in
            this Article XIII to "a Debenture" or "the Debentures"
            refers to the Debentures of the particular series that is
            convertible into Capital Stock.  Each reference in this
            Article to "Capital Stock" into which Debentures of any
            series are convertible refers to the class of Capital Stock
            into which the Debentures of such series are convertible in
            accordance with their terms (as specified as contemplated by
            Section 2.2).  If more than one series of Debentures with
            conversion privileges are outstanding at any time, the
            provisions of this Article XIII shall be applied separately
            to each such series.

                 SECTION 13.2.     Right of Debentureholders to convert
            Debentures.  Subject to and upon compliance with the terms
            of the Debentures and the provisions of Section 5.7 and this
            Article XIII, at the option of the holder thereof, any
            Debenture of any series of any authorized denomination, or
            any portion of the principal amount thereof which is $1,000
            or any integral multiple of $1,000, may, at any time during
            the period specified in the Debentures of such series, or in
            case such Debenture or portion thereof shall have been
            called for redemption, then in respect of such Debenture or
            portion thereof until and including, but not after (unless
            the Company shall default in payment due upon the redemption
            thereof) the close of business on the date fixed for
            redemption except that in the case of redemption at the
            option of the Debentureholder, if specified in the terms of
            such Debentures, such right shall terminate upon receipt of
            written notice of the exercise of such option, be converted
            into duly

                                  -71-




            authorized, validly issued, fully paid and nonassessable
            shares of the class of Capital Stock, or combination
            thereof, as specified in such Debenture, at the conversion
            rate for each $1,000 principal amount of Debentures (such
            initial conversion rate reflecting an initial conversion
            price specified in such Debenture) in effect on the
            conversion date, or, in case an adjustment in the conversion
            rate has taken place pursuant to the provisions of Section
            13.5, then at the applicable conversion rate as so adjusted,
            upon surrender of the Debenture or Debentures, the principal
            amount of which is so to be converted, to the Company at any
            time during usual business hours at the office or agency to
            be maintained by it in accordance with the provisions of
            Section 4.2, accompanied by a written notice of election to
            convert as provided in Section 13.3 and, if so required by
            the Company and the Trustee, by a written instrument or
            instruments of transfer in form satisfactory to the Company
            and the Trustee duly executed by the registered holder or
            his attorney duly authorized in writing.  All Debentures
            surrendered for conversion shall, if surrendered to the
            Company or any conversion agent, be delivered to the Trustee
            for cancellation and cancelled by it, or shall, if
            surrendered to the Trustee, be cancelled by it, as provided
            in Section 2.11.

                 The initial conversion price or conversion rate in
            respect of a series of Debentures shall be specified on the
            Debentures of such series.  The conversion price or
            conversion rate will be subject to adjustment on the terms
            set forth in Section 13.5 or such other or different terms,
            if any, as may be specified by Section 2.2 for Debentures of
            such series.  Provisions of this Indenture that apply to
            conversion of all of a Debenture also apply to conversion of
            a portion of it.

                 SECTION 13.3.     Issuance of shares of Capital Stock
            on conversion.  As promptly as practicable after the
            surrender, as herein provided, of any Debenture or
            Debentures for conversion, the Company shall deliver or
            cause to be delivered at its said office or agency to or
            upon the written order of the holder of the Debenture or
            Debentures so surrendered a certificate or certificates
            representing the number of duly authorized, validly issued,
            fully paid and nonassessable shares of Capital Stock into
            which such Debenture or Debentures may be converted in
            accordance with the terms thereof and the provisions of this
            Article XIII.  Prior to delivery of such certificate or
            certificates, the Company shall require a written notice at
            its said office or agency from the holder of the Debenture
            or Debentures so surrendered stating that the holder
            irrevocably elects to convert such Debenture or Debentures,
            or, if less than the entire principal amount thereof is to
            be converted, stating the portion thereof to be converted.
            Such notice shall also state the name or names (with address
            and social security or other taxpayer identification number)
            in which said certificate or certificates are to be issued.
            Such conversion shall be deemed to have been made at the
            time that such Debenture or Debentures shall have

                                  -72-




            been surrendered for conversion and such notice shall have
            been received by the Company or the Trustee, the rights of
            the holder of such Debenture or Debentures as a
            Debentureholder shall cease at such time, the person or
            persons entitled to receive the shares of Capital Stock upon
            conversion of such Debenture or Debentures shall be treated
            for all purposes as having become the record holder or
            holders of such shares of Capital Stock at such time and
            such conversion shall be at the conversion rate in effect at
            such time.  In the case of any Debenture of any series which
            is converted in part only, upon such conversion, the Company
            shall execute and the Trustee or any Authenticating Agent
            shall authenticate and deliver to the holder thereof, as
            requested by such holder, a new Debenture or Debentures of
            such series of authorized denominations in aggregate
            principal amount equal to the unconverted portion of such
            Debenture.

                 If the last day on which a Debenture may be converted
            is not a Business day in a place where a conversion agent is
            located, the Debenture may be surrendered to that conversion
            agent on the next succeeding day that is a Business day.

                 The Company will not be required to deliver
            certificates for shares of Capital Stock upon conversion
            while its stock transfer books are closed for a meeting of
            shareholders or for the payment of dividends or for any
            other purpose, but certificates for shares of Capital Stock
            shall be delivered as soon as the stock transfer books shall
            again be opened.

                 SECTION 13.4.     No payment or adjustment for interest
            or dividends. Unless otherwise specified as contemplated by
            Section 2.2 for Debentures of such series, Debentures
            surrendered for conversion during the period from the close
            of business on any regular record date (or special record
            date for payment of defaulted interest) next preceding any
            interest payment date to the opening of business on such
            interest payment date (except Debentures called for
            redemption on a redemption date within such period) when
            surrendered for conversion must be accompanied by payment of
            an amount equal to the interest thereon which the registered
            holder is to receive on such interest payment date.  Payment
            of interest shall be made as of such interest payment date
            or such date, as the case may be, to the holder of record of
            the Debentures as of such regular, or special record date,
            as applicable.  Except where Debentures surrendered for
            conversion must be accompanied by payment as described
            above, no interest on converted Debentures will be payable
            by the Company on any interest payment date subsequent to
            the date of conversion.  No other payment or adjustment for
            interest or dividends is to be made upon conversion.
            Notwithstanding the foregoing, upon conversion of any
            Debentures with original issue discount, the fixed number of
            shares of Capital Stock into which such Debenture is
            convertible delivered by the Company to the holder thereof
            shall be applied, first, to pay the accrued original issue
            discount attributable to the period from the date of
            issuance to

                                  -73-




            the date of conversion of such Debenture, and, second, to
            pay the balance of the principal amount of such Debenture.

                 SECTION 13.5.     Adjustment of conversion rate.
            Unless otherwise specified as contemplated by Section 2.2
            for Debentures of such series, the conversion rate for
            Debentures in effect at any time shall be subject to
            adjustment as follows:

                       (a)   In case the Company shall (i) declare a
                 dividend or make a distribution on the class of Capital
                 Stock into which Debentures of such series are
                 convertible in shares of its Capital Stock, (ii)
                 subdivide the outstanding shares of the class of
                 Capital Stock into which Debentures of such series are
                 convertible into a greater number of shares, (iii)
                 combine the outstanding shares of the class of Capital
                 Stock into which Debentures of such series are
                 convertible into a smaller number of shares, or (iv)
                 issue by reclassification of the shares of the class of
                 Capital Stock into which Debentures of such series are
                 convertible (including any such reclassification in
                 connection with a consolidation or merger in which the
                 Company is the continuing corporation) any shares, the
                 conversion rate for the Debentures of such series in
                 effect at the time of the record date for such dividend
                 or distribution, or the effective date of such
                 subdivision, combination or reclassification, shall be
                 proportionately adjusted so that the holder of any
                 Debenture of such series surrendered for conversion
                 after such time shall be entitled to receive the number
                 and kind of shares which he would have owned or have
                 been entitled to receive had such Debenture been
                 converted immediately prior to such time.  Similar
                 adjustments shall be made whenever any event listed
                 above shall occur.

                       (b)   In case the Company shall fix a record date
                 for the issuance of rights or warrants to all holders
                 of the class of Capital Stock into which Debentures of
                 such series are convertible entitling them (for a
                 period expiring within 45 days after such record date)
                 to subscribe for or purchase shares of such class of
                 Capital Stock (or securities convertible into shares of
                 such class of Capital Stock ) at a price per share (or,
                 in the case of a right or warrant to purchase
                 securities convertible into such class of Capital
                 Stock, having a conversion price per share, after
                 adding thereto the exercise price, computed on the
                 basis of the maximum number of shares of such class of
                 Capital Stock issuable upon conversion of such
                 convertible securities, per share of such class of
                 Capital Stock, so issuable) less than the current
                 market price per share of such class of Capital Stock
                 (as defined in subsection (d) below) on the date on
                 which such issuance was declared or otherwise announced
                 by the Company (the "Determination Date"), the number
                 of shares of such class of Capital Stock into which
                 each $1,000 principal amount of Debentures shall be
                 convertible after such record date shall be determined
                 by multiplying the

                                  -74-




                 number of shares of such class of Capital Stock into
                 which such principal amount of Debentures was
                 convertible immediately prior to such record date by a
                 fraction, of which the numerator shall be the number of
                 shares of such class of Capital Stock outstanding on
                 the Determination Date plus the number of additional
                 shares of such class of Capital Stock offered for
                 subscription or purchase (or in the case of a right or
                 warrant to purchase securities convertible into such
                 class of Capital Stock, the aggregate number of
                 additional shares of such class of Capital Stock into
                 which the convertible securities so offered are
                 initially convertible), and of which the denominator
                 shall be the number of shares of such class of Capital
                 Stock outstanding on the Determination Date plus the
                 number of shares of such class of Capital Stock
                 obtained by dividing the aggregate offering price of
                 the total number of shares so offered (or, in the case
                 of a right or warrant to purchase securities
                 convertible into such class of Capital Stock, the
                 aggregate initial conversion price of the convertible
                 securities so offered, after adding thereto the
                 aggregate exercise price of such rights or warrants
                 computed on the basis of the maximum number of shares
                 of such class of Capital Stock issuable upon conversion
                 of such convertible securities) by such current market
                 price.  Shares of such class of Capital Stock of the
                 Company owned by or held for the account of the Company
                 shall not be deemed outstanding for the purpose of any
                 such computation.  Such adjustment shall be made
                 successively whenever such a record date is fixed; and
                 to the extent that shares of such class of Capital
                 Stock are not delivered (or securities convertible into
                 shares of such class of Capital Stock are not
                 delivered) after the expiration of such rights or
                 warrants (or, in the case of rights or warrants to
                 purchase securities convertible into such class of
                 Capital Stock once exercised, the expiration of the
                 conversion right of such securities) the conversion
                 rate shall be readjusted to the conversion rate which
                 would then be in effect had the adjustments made upon
                 the issuance of such rights or warrants (or securities
                 convertible into shares) been made upon the basis of
                 delivery of only the number of shares actually
                 delivered.  In the event that such rights or warrants
                 are not so issued, the conversion rate shall again be
                 adjusted to be the conversion rate which would then be
                 in effect if such record date had not been fixed.

                       (c)   In case the Company shall fix a record date
                 for the making of a distribution to all holders of the
                 class of Capital Stock into which Debentures of such
                 series are convertible (including any such distribution
                 made in connection with a consolidation or merger in
                 which the Company is the continuing corporation) of
                 evidences of its indebtedness or assets (excluding any
                 cash dividends paid from retained earnings and
                 dividends payable in Capital Stock for which adjustment
                 is made pursuant to subsection (a)

                                  -75-




                 above) or subscription rights or warrants (excluding
                 subscription rights or warrants to purchase the class
                 of Capital Stock into which Debentures of such series
                 are convertible), the number of shares of such class of
                 Capital Stock into which each $1,000 principal amount
                 of Debentures of such series shall be convertible after
                 such record date shall be determined by multiplying the
                 number of shares of such class of Capital Stock into
                 which such principal amount of Debentures was
                 convertible immediately prior to such record date by a
                 fraction, of which the numerator shall be the fair
                 market value of the assets of the Company, after
                 deducting therefrom all liabilities of the Company and
                 all preferences (including accrued but unpaid
                 dividends) in respect of classes of Capital Stock
                 having a preference with respect to the assets of the
                 Company over such class of Capital Stock (all as
                 determined by the Board of Directors, whose
                 determination shall be conclusive, and described in a
                 certificate signed by any Vice Chairmen of the Board,
                 Vice President or Assistant Vice President and
                 Treasurer of the Company, filed with the Trustee and
                 each conversion agent) on such record date, and of
                 which the denominator shall be such fair market value
                 after deducting therefrom such liabilities and
                 preferences, less the fair market value (as determined
                 by the Board of Directors, whose determination shall be
                 conclusive, and described in a statement filed with the
                 Trustee and each conversion agent) of the assets or
                 evidences of indebtedness, so distributed or of such
                 subscription rights or warrants applicable, so
                 distributed.  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 rate shall again be adjusted to the
                 conversion rate which would then be in effect if such
                 record date had not been fixed.

                       (d)   For the purpose of any computation under
                 subsection (b) above and Section 13.6, the current
                 market price per share of the Capital Stock on any date
                 as of which such price is to be computed shall mean the
                 average of the Closing Prices for the 30 consecutive
                 Business days commencing 45 Business days before such
                 date.

                       (e)   No adjustment in the conversion rate shall
                 be required unless such adjustment would require a
                 cumulative increase or decrease of at least 1% in such
                 rate; provided, however, that any adjustments which by
                 reason of this subsection (e) are not required to be
                 made shall be carried forward and taken into account in
                 any subsequent adjustment, and provided, further, that
                 adjustments shall be required and made in accordance
                 with the provisions of this Article XIII (other than
                 this subsection (e)) not later than such time as may be
                 required in order to preserve the tax-free nature of a
                 distribution for United States income tax purposes to
                 the holders of Debentures or the class of Capital Stock
                 into

                                  -76-




                 which such Debentures are convertible.  All
                 calculations under this Article XIII shall be made to
                 the nearest cent or to the nearest one-thousandth of a
                 share, as the case may be.  Anything in this Section
                 13.5 to the contrary notwithstanding, the Company shall
                 be entitled to make such adjustments in the conversion
                 rate, in addition to those required by this Section
                 13.5, as it in its discretion shall determine to be
                 advisable in order that any stock dividend, subdivision
                 of shares, distribution of rights to purchase stock or
                 securities, or distribution of securities convertible
                 into or exchangeable for stock hereafter made by the
                 Company to its shareholders shall not be taxable for
                 United States income tax purposes.

                       (f)   Whenever the conversion rate is adjusted,
                 as herein provided, the Company shall promptly file
                 with the Trustee and with the office or agency
                 maintained by the Company for the conversion of
                 Debentures of such series pursuant to Section 4.2, a
                 certificate of a firm of independent public accountants
                 of recognized national standing selected by the Board
                 of Directors (who may be the regular accountants
                 employed by the Company) setting forth the conversion
                 rate after such adjustment and setting forth a brief
                 statement of the facts requiring such adjustment and a
                 computation thereof.  Such certificate shall be
                 conclusive evidence of the correctness of such
                 adjustment.  Neither the Trustee nor any conversion
                 agent shall be under any duty or responsibility with
                 respect to any such certificate or any facts or
                 computations set forth therein, except to exhibit said
                 certificate from time to time to any Debentureholder of
                 such series desiring to inspect the same.  The Company
                 shall promptly cause a notice setting forth the
                 adjusted conversion rate to be mailed to the holders of
                 Debentures of such series, as their names and addresses
                 appear upon the registration books of the Company.

                       (g)   In the event that at any time, as a result
                 of shares of any other class of Capital Stock becoming
                 issuable in exchange or substitution for or in lieu of
                 shares of the class of Capital Stock into which such
                 Debentures are convertible or as a result of an
                 adjustment made pursuant to subsection (a) above, the
                 holder of any Debenture of such series thereafter
                 surrendered for conversion shall become entitled to
                 receive any shares of the Company other than shares of
                 the class of Capital Stock into which the Debentures of
                 such series are convertible, thereafter the number of
                 such other shares so receivable upon conversion of any
                 Debenture shall be subject to adjustment from time to
                 time in a manner and on terms as nearly equivalent as
                 practicable to the provisions with respect to the class
                 of Capital Stock into which the Debentures of such
                 series are convertible contained in subsections (a) to
                 (f), inclusive, above, and the provisions of this
                 Article XIII with respect

                                  -77-




                 to the class of Capital Stock into which the Debentures
                 of such series are convertible shall apply on like
                 terms to any such other shares.

                       (h)   The conversion rate with respect to any
                 Debentures with original issue discount, the terms of
                 which provide for convertibility, shall not be adjusted
                 during the term of such Original Issue Discount
                 Debentures for accrued original issue discount.

                       (i)   In the event that the Debentures of any
                 series are convertible into more than one class of
                 Capital Stock, the provisions of this Section 13.5
                 shall apply separately to events affecting each such
                 class.

                 SECTION 13.6.     No fractional shares to be issued.
            No fractional shares of Capital Stock shall be issued upon
            conversions of Debentures.  If more than one Debenture of
            any series shall be surrendered for conversion at one time
            by the same holder, the number of full shares which shall be
            issuable upon conversion thereof shall be computed on the
            basis of the aggregate principal amount of the Debentures of
            such series (or specified portions thereof to the extent
            permitted hereby) so surrendered.  Instead of a fraction of
            a share of Capital Stock which would otherwise be issuable
            upon conversion of any Debenture or Debentures (or specified
            portions thereof), the Company shall pay a cash adjustment
            in respect of such fraction of a share in an amount equal to
            the same fractional interest of the current market price (as
            defined in Section 13.5) per share of Capital Stock on the
            Business day next preceding the day of conversion.

                 SECTION 13.7.  Preservation of conversion rights upon
            consolidation, merger, sale or conveyance.  In case of any
            consolidation of the Company with, or merger of the Company
            into, any other corporation (other than a consolidation or
            merger in which the Company is the continuing corporation),
            or in the case of any sale or transfer of all or
            substantially all of the assets of the Company, the
            corporation formed by such consolidation or the corporation
            into which the Company shall have been merged or the
            corporation which shall have acquired such assets, as the
            case may be, shall execute and deliver to the Trustee, a
            supplemental indenture, subject to the provisions of Article
            X and XII as they relate to supplemental indentures,
            providing that the holder of each Debenture then Outstanding
            of a series which was convertible into Capital Stock shall
            have the right thereafter to convert such Debenture into the
            kind and amount of shares of stock and other securities and
            property, including cash, receivable upon such
            consolidation, merger, sale or transfer by a holder of the
            number of shares of Capital Stock of the Company into which
            such Debentures might have been converted immediately prior
            to such consolidation, merger, sale or transfer.  Such
            supplemental indenture shall conform to the

                                  -78-




            provisions of the Trust Indenture Act of 1939 as then in
            effect and shall provide for adjustments which shall be as
            nearly equivalent as may be practicable to the adjustments
            provided for in this Article XIII.  Neither the Trustee nor
            any conversion agent shall be under any responsibility to
            determine the correctness of any provision contained in any
            such supplemental indenture relating either to the kind or
            amount of shares of stock or other securities or property
            receivable by Debentureholders upon the conversion of their
            Debentures after any such consolidation, merger, sale or
            transfer, or to any adjustment to be made with respect
            thereto and, subject to the provisions of Section 11.1, may
            accept as conclusive evidence of the correctness of any such
            provisions, and shall be protected in relying upon, an
            Opinion of Counsel with respect thereto.  If in the case of
            any such consolidation, merger, sale or transfer, the stock
            or other securities and property receivable by a holder of
            the Debentures includes stock or other securities and
            property of a corporation other than the successor or
            purchasing corporation, then such supplemental indenture
            shall also be executed by such other corporation and shall
            contain such additional provisions to protect the interests
            of the holders of the Debentures as the Board of Directors
            shall reasonably consider necessary.  The above provisions
            of this Section 13.7 shall similarly apply to successive
            consolidations, mergers, sales or transfers.


                 SECTION 13.8.  Notice to Debentureholders of a series
            prior to taking certain types of action.  With respect to
            the Debentures of any series, in case:

                       (a) the Company shall authorize the issuance to
                 all holders of the class of Capital Stock into which
                 Debentures of such series are convertible of rights or
                 warrants to subscribe for or purchase shares of its
                 Capital Stock or of any other right;

                       (b) the Company shall authorize the distribution
                 to all holders of the class of Capital Stock into which
                 Debentures of such series are convertible of evidences
                 of its indebtedness or assets (except for the
                 exclusions with respect to certain dividends set forth
                 in Section 13.5(c);

                       (c) of any subdivision, combination or
                 reclassification of the class of Capital Stock into
                 which Debentures of such series are convertible or of
                 any consolidation or merger to which the Company is a
                 party and for which approval by the shareholders of the
                 Company is required, or of the sale or transfer of all
                 or substantially all of the assets of the Company; or

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

            then the Company shall cause to be filed with the Trustee
            and at

                                  -79-




            the office or agency maintained for the purpose of
            conversion of Debentures of such series pursuant to Section
            4.2, and shall cause to be mailed to the holders of
            Debentures of such series, at their last addresses as they
            shall appear upon the registration books of the Company, at
            least ten days prior to the applicable record date
            hereinafter specified, a notice stating (i) the date as of
            which the holders of such class of Capital Stock to be
            entitled to receive any such rights, warrants or
            distribution are to be determined, or (ii) the date on which
            any such subdivision, combination, reclassification,
            consolidation, merger, sale, transfer, dissolution,
            liquidation, winding up or other action is expected to
            become effective, and the date as of which it is expected
            that holders of record of such class of Capital Stock shall
            be entitled to exchange their Capital Stock of such class
            for securities or other property, if any, deliverable upon
            such subdivision, combination, reclassification,
            consolidation, merger, sale, transfer, dissolution,
            liquidation, winding up or other action. The failure to give
            the notice required by this Section 13.8 or any defect
            therein shall not affect the legality or validity of any
            distribution, right, warrant, subdivision, combination,
            reclassification, consolidation, merger, sale, transfer,
            dissolution, liquidation, winding up or other action, or the
            vote upon any of the foregoing.  Such notice shall also be
            published by and at the expense of the Company not later
            than the aforesaid filing date at least once in an
            Authorized Newspaper.

                 SECTION 13.9.  Covenant to reserve shares for issuance
            on conversion of Debentures.  The Company covenants that at
            all times it will reserve and keep available out of each
            class of its authorized Capital Stock, free from preemptive
            rights, solely for the purpose of issue upon conversion of
            Debentures of any series as herein provided, such number of
            shares of Capital Stock of such class as shall then be
            issuable upon the conversion of all Outstanding Debentures
            of such series.  The Company covenants that all shares of
            Capital Stock which shall be so issuable shall, when issued
            or delivered, be duly and validly issued shares of the class
            of authorized Capital Stock into which Debentures of such
            series are convertible, and shall be fully paid and
            nonassessable, free of all liens and charges and not subject
            to preemptive rights and that, upon conversion, the
            appropriate capital stock accounts of the Company will be
            duly credited.

                 SECTION 13.10.  Compliance with governmental
            requirements.  The Company covenants that if any shares of
            Capital Stock required to be reserved for purposes of
            conversion of Debentures hereunder require registration or
            listing with or approval of any governmental authority under
            any Federal or State law, pursuant to the Securities Act of
            1933, as amended, or the Securities Exchange Act, or any
            national or regional securities exchange on which such
            Capital Stock is listed at the time of delivery of any
            shares of such Capital Stock, before such shares may be
            issued

                                  -80-




            upon conversion, the Company will use its best efforts to
            cause such shares to be duly registered, listed or approved,
            as the case may be.

                 SECTION 13.11.  Payment of taxes upon certificates for
            shares issued upon conversion.  The issuance of certificates
            for shares of Capital Stock upon the conversion of
            Debentures shall be made without charge to the converting
            Debentureholders for any tax (including, without limitation,
            all documentary and stamp taxes) in respect of the issuance
            and delivery of such certificates, and such certificates
            shall be issued in the respective names of, or in such names
            as may be directed by, the holders of the Debentures
            converted; provided, however, that the Company shall not be
            required to pay any tax which may be payable in respect of
            any transfer involved in the issuance and delivery of any
            such certificate in a name other than that of the holder of
            the Debenture converted, and the Company shall not be
            required to issue or deliver such certificates unless or
            until the person or persons requesting the issuance thereof
            shall have paid to the Company the amount of such tax or
            shall have established to the satisfaction of the Company
            that such tax has been paid.

                 SECTION 13.12.  Trustee's duties with respect to
            conversion provisions. The Trustee and any conversion agent
            shall not at any time be under any duty or responsibility to
            any Debentureholder to determine whether any facts exist
            which may require any adjustment of the conversion rate, 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 any supplemental indenture provided to be employed, in
            making the same.  Neither the Trustee nor any conversion
            agent shall be accountable with respect to the registration
            under securities laws, listing, validity or value (or the
            kind or amount) of any shares of Capital Stock, or of any
            other securities or property, which may at any time be
            issued or delivered upon the conversion of any Debenture;
            and neither the Trustee nor any conversion agent makes any
            representation with respect thereto.  Neither the Trustee
            nor any conversion agent shall be responsible for any
            failure of the Company to make any cash payment or to issue,
            transfer or deliver any shares of stock or stock
            certificates or other securities or property upon the
            surrender of any Debenture for the purpose of conversion;
            and the Trustee, subject to the provisions of Section 11.1,
            and any conversion agent shall not be responsible for any
            failure of the Company to comply with any of the covenants
            of the Company contained in this Article XIII.

                              ARTICLE XIV

                        MISCELLANEOUS PROVISIONS


                 SECTION 14.1.  Rights under Indenture limited to the
            parties and holders of Debentures.  Except as provided in
            Article III, nothing in this Indenture or the Debentures,
            express or implied,

                                  -81-




            is intended or shall be construed to confer upon, or to give
            to, any person or corporation, other than the parties
            hereto, their successors and assigns, and the holders of the
            Debentures, any right, remedy or claim under or by reason of
            this Indenture or any provision hereof; and the provisions
            of this Indenture are for the exclusive benefit of the
            parties hereto, their successors and assigns, and the
            holders of the Debentures.

                 SECTION 14.2.  Certificate of independent accountants
            conclusive.  Unless otherwise specifically provided, the
            certificate or opinion of Arthur Andersen & Co., or of any
            other independent firm of public accountants of recognized
            standing selected by the Board of Directors and acceptable
            to the Trustee in the exercise of reasonable care (which
            firm may be regular independent accountants to the Company),
            shall be conclusive evidence of the correctness of any
            computation made under the provisions of this Indenture, and
            wherever reference is made in this Indenture to "generally
            accepted accounting principles" the certificate or opinion
            of such a firm shall be conclusive evidence thereof.  The
            Company shall furnish to the Trustee upon its request a copy
            of any such certificate or opinion.

                 SECTION 14.3.  Treatment of Debentures owned or held by
            the Company in determining required percentages.  For all
            purposes of this Indenture, in determining whether the
            holders of a required percentage or proportion of the
            principal amount of Debentures of one or more series have
            concurred in any request, waiver, vote, direction or
            consent, Debentures owned or held by or for the account or
            for the benefit of the Company or any other obligor under
            this Indenture or any Affiliate shall be disregarded and
            deemed not Outstanding, except that, for the purposes of
            determining whether the Trustee shall be protected in
            relying on any such request, waiver, direction or consent,
            only Debentures which the Trustee knows to be so owned or
            held shall be so disregarded.  Debentures so owned which
            have been pledged in good faith to secure an obligation may
            be regarded as Outstanding for all such purposes, if the
            Trustee receives an Officers' Certificate stating that said
            Debentures have been so pledged, that the pledgee is
            entitled to vote with respect to such Debentures and that
            the pledgee is not the Company or any other obligor on the
            Debentures, an Affiliate of the Company or an Affiliate of
            such other obligor. In case of a dispute as to such right,
            any decision by the Trustee taken upon the advice of counsel
            shall be conclusive, and, subject to the provisions of
            Section 11.1 of this Indenture, shall afford full protection
            to the Trustee.

                 SECTION 14.4.  Remaining provisions not affected by
            invalidity of any other provisions-required provisions of
            Trust Indenture Act of 1939 to control.  In case anyone or
            more of the provisions contained in this Indenture or in the
            Debentures of any series shall for any reason be held to be
            invalid, illegal or unenforceable in any respect, such
            invalidity, illegality or

                                  -82-




            unenforceability shall not affect any other provision of
            this Indenture, but this Indenture shall be construed as if
            such invalid, illegal or unenforceable provisions had never
            been contained herein.

                 If any provision of this Indenture limits, qualifies or
            conflicts with any other provision of this Indenture which
            is required to be included in an indenture qualified under
            the Trust Indenture Act of 1939, as amended, such provision
            which is so required to be included shall control.

                 SECTION 14.5.  Company released from Indenture
            requirements if entitled to have Indenture cancelled.
            Whenever by the terms of this Indenture the Company shall be
            required to do or not to do anything so long as any of the
            Debentures shall be Outstanding of any series, the Company
            shall, notwithstanding any such provision, not be required
            to comply with such provision with respect to such series if
            it shall be entitled to have this Indenture satisfied and
            discharged pursuant to the provisions hereof, even though in
            either case the holders of any of the Debentures of such
            series shall have failed to present and surrender such
            Debentures for payment pursuant to the terms of this
            Indenture.

                 SECTION 14.6.  Date of execution.  Although this
            Indenture, for convenience and for the purpose of reference,
            is dated as of the date first above written, the actual date
            of execution by the Company and by the Trustee is as
            indicated by their respective acknowledgements hereto
            annexed.

                 SECTION 14.7.  Execution of documents furnished under
            the Indenture. Unless otherwise expressly provided, any
            order, notice, request, demand, certificate or statement of
            the Company required or permitted to be made or given under
            any provision hereof shall be sufficiently executed if
            signed by its Chairman of the Board, President, any Vice
            Chairman of the Board or any Vice President, and by its
            Treasurer, any Assistant Treasurer, Secretary or any
            Assistant Secretary.

                 SECTION 14.8.  Officers' Certificates and Opinions of
            Counsel to be furnished Trustee.  Upon any application,
            demand or request by the Company to the Trustee to take any
            action under any of the provisions of this Indenture, the
            Company shall furnish to the Trustee an Officers'
            Certificate stating that all conditions precedent, if any,
            provided for in this Indenture relating to the proposed
            action have been complied with, and an Opinion of Counsel
            stating that in the opinion of such counsel all such
            conditions precedent have been complied with and that such
            action is in compliance with applicable law.

                 Each certificate or opinion with respect to compliance
            with a condition or covenant provided for in this Indenture
            shall include (a) a statement that the person making such
            certificate

                                  -83-




            or opinion has read such covenant or condition; (b) a brief
            statement as to the nature and scope of the examination or
            investigation upon which the statements or opinions
            contained in such certificate or opinion are based; (c) a
            statement that, in the opinion of such person, he has made
            such examination or investigation as is necessary to enable
            him to express an informed opinion as to whether or not such
            covenant or condition has been complied with; and (d) a
            statement as to whether or not, in the opinion of such
            person, such condition or covenant has been complied with.

                 Any certificate, statement or opinion of an officer of
            the Company may be based, insofar as it relates to legal
            matters, upon a certificate or opinion of or representations
            by counsel, unless such officer knows that the certificate
            or opinion or representations with respect to the matters
            upon which his certificate, statement or opinion may be
            based as aforesaid are erroneous, or in the exercise of
            reasonable care should know that the same are erroneous.
            Any certificate, statement or opinion of counsel may be
            based, insofar as it relates to factual matters, information
            with respect to which is in the possession of the Company,
            upon the certificate, statement or opinion of or
            representations by an officer or officers of the Company,
            unless such counsel knows that the certificate, statement or
            opinion or representations with respect to the matters upon
            which his certificate, statement or opinion may be based as
            aforesaid are erroneous, or in the exercise of reasonable
            care should know that the same are erroneous.

                 Any certificate, statement or opinion of an officer of
            the Company or of counsel may be based, insofar as it
            relates to accounting matters, upon a certificate or opinion
            of or representations by an accountant or firm of
            accountants in the employ of the Company, unless such
            officer or counsel, as the case may be, knows that the
            certificate or opinion or representations with respect to
            the accounting matters upon which his certificate, statement
            or opinion may be based as aforesaid are erroneous, or in
            the exercise of reasonable care should know that the same
            are erroneous.  Any certificate or opinion of any
            independent firm of public accountants filed with the
            Trustee shall contain a statement that such firm is
            independent.

                 SECTION 14.9.  Presentation of notices and demands.
            All notices to or demands upon the Trustee shall be in
            writing and may be served or presented at the principal
            office of the Trustee.  Any notice to or demand upon the
            Company shall be deemed to have been sufficiently given or
            served by the Trustee or the Debentureholders, for all
            purposes, by being mailed by first class mail addressed to
            the Company, attention of the President, at 2002 Pisgah
            Church Road, Suite 300, Greensboro, North Carolina 27455,
            and to Schell Bray Aycock Abel & Livingston, 230 North Elm
            Street, Suite 1500, Greensboro, North Carolina 27401,
            Attention: Kenneth N. Shelton, Esq., or at such

                                  -84-




            other address or to such other counsel, as may be filed in
            writing by the Company with the Trustee.

                 Except as otherwise expressly provided herein, where
            this Indenture provides for notice to holders of Debentures
            of any event, such notice shall be sufficiently given to
            holders of Debentures if in writing and mailed, first-class
            postage prepaid, to each holder of a Debenture affected by
            such event, at the address of such holder as it appears in
            the Debenture register, not later than the latest date, and
            not earlier than the earliest date, prescribed for the
            giving of such notice.

                 In case by reason of the suspension of regular mail
            service or by reason of any other cause it shall be
            impracticable to give such notice to holders of Debentures
            by mail, then such notification as shall be made with the
            approval of the Trustee shall constitute a sufficient
            notification for every purpose hereunder.  In any case where
            notice to holders of Debentures is given by mail, neither
            the failure to mail such notice, nor any defect in any
            notice so mailed, to any particular holder of a Debenture
            shall affect the sufficiency of such notice with respect to
            other holders of Debentures.

                 SECTION 14.10.  Successors and assigns bound by
            Indenture.  All the covenants, promises and agreements in
            this Indenture contained by or on behalf of the Company, or
            by or on behalf of the Trustee, shall bind and inure to the
            benefit of their respective successors and assigns, whether
            so expressed or not.

                 SECTION 14.11  Descriptive headings for convenience
            only.  The descriptive headings of the several Articles of
            this Indenture are inserted for convenience only and shall
            not control or affect the meaning or construction of any of
            the provisions hereof.

                 SECTION 14.12.  North Carolina law to govern.  This
            Indenture and each Debenture shall be deemed to be a
            contract made under the laws of the State of North Carolina,
            and for all purposes shall be construed in accordance with
            the laws of said jurisdiction, except that the rights,
            obligations, duties, immunities and limitations of rights of
            the Trustee shall be construed in accordance with the laws
            of the State of              .

                 SECTION 14.13.  Indenture may be executed in
            counterparts.  This Indenture may be simultaneously executed
            in any number of counterparts, each of which when so
            executed and delivered shall be an original, but such
            counterparts shall together constitute but one and the same
            instrument. , as Trustee, hereby accepts the trusts in this
            Indenture declared and provided upon the terms and
            conditions hereinbefore set forth.

                                  -85-
