              by check mailed to the address of such person on the registry
              kept for such purposes; provided that, with respect to any
              holder of Notes with an aggregate principal amount equal to
              or in excess of $5,000,000, at the request of such holder in
              writing to the Company (who shall then furnish written notice
              to such effect to the Trustee), interest on such holder's
              Notes shall be paid by wire transfer (the costs of such wire
              transfer to be borne by the Company) in immediately available
              funds in accordance with the wire transfer instructions
              supplied by such holder to the Trustee and paying agent (if

              a 360-day year comprised of twelve 30-day months.

                   Any interest on any Note which is payable, but is not
              punctually paid or duly provided for, on any said March 15 or
              September 15 (herein called "Defaulted Interest") shall
              forthwith cease to be payable to the Noteholder on the
              relevant record date by virtue of his having been such
              Noteholder; and such Defaulted Interest shall be paid by the
              Company, at its election in each case, as provided in clause
              (A) or (B) below:  

                        (A)  The Company may elect to make payment of any
              Defaulted Interest to the Persons in whose names the Notes
              (or their respective Predecessor Notes) are registered at the
              close of business on a special record date for the payment of
              such Defaulted Interest, which shall be fixed in the
              following manner.  The Company shall notify the Trustee in
              writing of the amount of Defaulted Interest to be paid on
              each Note and the date of the payment (which shall be not
              less than twenty-five (25) days after the receipt by the
              Trustee of such notice, unless the Trustee shall consent to
              an earlier date), and at the same time the Company shall
              deposit with the Trustee an amount of money equal to the
              aggregate amount to be paid in respect of such Defaulted
              Interest or shall make arrangements satisfactory to the
              Trustee for such deposit prior to the date of the proposed
              payment, such money when deposited to be held in trust for
              the benefit of the


                                        -10-





              Persons entitled to such Defaulted Interest as in this clause
              provided.  Thereupon the Trustee shall fix a special record
              date for the payment of such Defaulted Interest which shall
              be not more than fifteen (15) days and not less than ten (10)
              days prior to the date of the proposed payment and not less
              than ten (10) days after the receipt by the Trustee of the
              notice of the proposed payment.  The Trustee shall promptly
              notify the Company of such special record date and, in the
              name and at the expense of the Company, shall cause notice of
              the proposed payment of such Defaulted Interest and the
              special record date therefor to be mailed, first-class
              postage prepaid, to each Noteholder as of such special record
              date at his address as it appears in the Note register, not
              less than ten (10) days prior to such special record date.
              Notice of the proposed payment of such Defaulted Interest and
              the special record date therefor having been so mailed, such
              Defaulted Interest shall be paid to the Persons in whose
              names the Notes (or their respective Predecessor Notes) were
              registered at the close of business on such special record
              date and shall no longer be payable pursuant to the following
              clause (B).

                        (B)  The Company may make payment of any Defaulted
              Interest in any other lawful manner not inconsistent with the
              requirements of any securities exchange and automated
              quotation system on which the Notes may be listed or
              designated for issuance, and upon such notice as may be
              required by such exchange and automated quotation system, if,
              after notice given by the Company to the Trustee of the
              proposed payment pursuant to this clause, such manner of
              payment shall be deemed practicable by the Trustee.

                       Section 2.4  EXECUTION OF NOTES.  The Notes shall be
              signed in the name and on behalf of the Company by the manual

              President, any Executive or Senior Vice President or any Vice

              or word or words added before or after the title "Vice
              President") and attested by the manual or facsimile signature
              of its Secretary or any of its Assistant Secretaries (which
              may be printed, engraved or otherwise reproduced thereon, by
              facsimile or otherwise).  Only such Notes as shall bear
              thereon a certificate of authentication substantially in the
              form set forth on the form of Note attached as Exhibit A
              hereto, manually executed by the Trustee (or an
              authenticating agent appointed by the Trustee as provided by
              Section 17.11), shall be entitled to the benefits of this
              Indenture or be valid or obligatory for any purpose.  Such
              certificate by the Trustee (or such an authenticating agent)
              upon any Note executed by the Company shall be conclusive
              evidence that the Note so authenticated has been duly
              authenticated and delivered hereunder and that the holder is
              entitled to the benefits of this Indenture. 


                                        -11-





                   In case any officer of the Company who shall have signed
              any of the Notes shall cease to be such officer before the
              Notes so signed shall have been authenticated and delivered
              by the Trustee, or disposed of by the Company, such Notes
              nevertheless may be authenticated and delivered or disposed
              of as though the person who signed such Notes had not ceased
              to be such officer of the Company; and any Note may be signed
              on behalf of the Company by such persons as, at the actual
              date of the execution of such Note, shall be the proper
              officers of the Company, although at the date of the
              execution of this Indenture any such person was not such an
              officer.

                   Section 2.5  EXCHANGE AND REGISTRATION OF TRANSFER OF
              NOTES.  The Company shall cause to be kept at the Corporate
              Trust Office a register (the register maintained in such
              office and in any other office or agency of the Company
              designated pursuant to Section 5.2 being herein sometimes
              collectively referred to as the "Note register") in which,
              subject to such reasonable regulations as it may prescribe,
              the Company shall provide for the registration of Notes and
              of transfers of Notes.  The Note register shall be in written
              form or in any form capable of being converted into written
              form within a reasonably prompt period of time. The Trustee
              is hereby appointed "Note registrar" for the purpose of
              registering Notes and transfers of Notes as herein provided.
              The Company may change the Note registrar or appoint one or
              more co-registrars in accordance with Section 5.2 without any
              prior notice to any holders, provided that a Note register
              shall be at all times maintained at the Corporate Trust
              Office.

                   Upon surrender for registration of transfer of any Note
              to the Note registrar or any co-registrar, and satisfaction
              of the requirements for such transfer set forth in this
              Section 2.5, the Company shall execute, and the Trustee shall
              authenticate and deliver, in the name of the designated
              transferee or transferees, one or more new Notes of any
              authorized denominations and of a like aggregate principal
              amount and bearing such restrictive legends as may be
              required by this Indenture.

                   Notes may be exchanged for other Notes of any authorized
              denominations and of a like aggregate principal amount, upon
              surrender of the Notes to be exchanged at any such office or
              agency maintained by the Company pursuant to Section 5.2.
              Whenever any Notes are so surrendered for exchange, the
              Company shall execute, and the Trustee shall authenticate and
              deliver, the Notes which the Noteholder making the exchange
              is entitled to receive bearing registration numbers not
              contemporaneously outstanding.

                   All Notes issued upon any registration of transfer or
              exchange of Notes shall be the valid obligations of the
              Company,


                                        -12-





              evidencing the same debt, and entitled to the same benefits
              under this Indenture, as the Notes surrendered upon such
              registration of transfer or exchange.

                   All Notes presented or surrendered for registration of
              transfer or for exchange, redemption, repurchase or
              conversion shall (if so required by the Company or the Note
              registrar) be duly endorsed, or be accompanied by a written
              instrument or instruments of transfer in form satisfactory to
              the Company, and the Notes shall be duly executed by the
              Noteholder thereof or his attorney duly authorized in
              writing. 

                   No service charge shall be made to a Noteholder for any
              registration of transfer or exchange of Notes, but the
              Company may require payment of a sum sufficient to cover any
              tax, assessment or other governmental charge that may be
              imposed in connection with any registration of transfer or
              exchange of Notes.

                   Neither the Company nor the Trustee nor any Note
              registrar or any Company registrar shall be required to
              exchange or register a transfer of (a) any Notes for a period
              of fifteen (15) days next preceding any selection of Notes to
              be redeemed or (b) any Notes or portions thereof called for
              redemption pursuant to Article III or (c) any Notes or
              portion thereof surrendered for conversion pursuant to
              Article XV.

                   Section 2.6  MUTILATED, DESTROYED, LOST OR STOLEN NOTES.
              In case any Note shall become mutilated or be destroyed, lost
              or stolen, the Company in its discretion may execute, and
              upon its request the Trustee or an authenticating agent
              appointed by the Trustee shall authenticate and deliver, a
              new Note, bearing a number not contemporaneously outstanding,
              in exchange and substitution for the mutilated Note, or in
              lieu of and in substitution for the Note so destroyed, lost
              or stolen.  In every case the applicant for a substituted
              Note shall furnish to the Company, to the Trustee and, if
              applicable, to such authenticating agent such security or
              indemnity as may be required by them to save each of them
              harmless for any loss, liability, cost or expense caused by
              or connected with such substitution, and, in every case of
              destruction, loss or theft, the applicant shall also furnish
              to the Company, to the Trustee and, if applicable, to such
              authenticating agent evidence to their satisfaction of the
              destruction, loss or theft of such Note and of the ownership
              thereof.

                   The Trustee or such authenticating agent may
              authenticate any such substituted Note and deliver the same
              upon the receipt of such security or indemnity as the
              Trustee, the Company and, if applicable, such authenticating
              agent may require.  Upon the issuance of any substituted
              Note, the Company may require from the


                                        -13-





              holder of such Note the payment of a sum sufficient to cover
              the Company's reasonable out-of-pocket expenses and any tax
              or other governmental charge that may be imposed in relation
              thereto and any other expenses connected therewith.  In case
              any Note which has matured or is about to mature or has been
              called for redemption or is about to be converted into Common
              Stock shall become mutilated or be destroyed, lost or stolen,
              the Company may, instead of issuing a substitute Note, pay or
              authorize the payment of or convert or authorize the
              conversion of the same (without surrender thereof except in
              the case of a mutilated Note), as the case may be, if the
              applicant for such payment or conversion shall furnish to the
              Company, to the Trustee and, if applicable, to such
              authenticating agent such security or indemnity as may be
              required by them to save each of them harmless for any loss,
              liability, cost or expense caused by or connected with such
              substitution, and, in case of destruction, loss or theft,
              evidence satisfactory to the Company, the Trustee and, if
              applicable, any paying agent or conversion agent of the
              destruction, loss or theft of such Note and of the ownership
              thereof.

                   Every substitute Note issued pursuant to the provisions
              of this Section 2.6 by virtue of the fact that any Note is
              destroyed, lost or stolen shall constitute an additional
              contractual obligation of the Company, whether or not the
              destroyed, lost or stolen Note shall be found at any time,
              and shall be entitled to all the benefits of (but shall be
              subject to all the limitations set forth in) this Indenture
              equally and proportionately with any and all other Notes duly
              issued hereunder.  To the extent permitted by law, all Notes
              shall be held and owned upon the express condition that the
              foregoing provisions are exclusive with respect to the
              replacement or payment or conversion of mutilated, destroyed,
              lost or stolen Notes and shall preclude 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 or conversion of negotiable
              instruments or other securities without their surrender.

                   Section 2.7 TEMPORARY NOTES.  Pending the preparation of
              definitive Notes, the Company may execute and the Trustee or
              an authenticating agent appointed by the Trustee shall, upon
              the written request of the Company, authenticate and deliver
              temporary Notes (printed, typewritten or lithographed).
              Temporary Notes shall be issuable in any authorized
              denomination, and substantially in the form of the definitive
              Notes, but with such omissions, insertions and variations as
              may be appropriate for temporary Notes, all as may be
              determined by the Company.  Every such temporary Note shall
              be executed by the Company and authenticated by the Trustee
              or such authenticating agent upon the same conditions and in
              substantially the same manner, and with the same effect, as
              the definitive Notes.  Without unreasonable delay


                                        -14-





              the Company will execute and deliver to the Trustee or such
              authenticating agent definitive Notes (other than in the case
              of Notes in global form) and thereupon any or all temporary
              Notes (other than any such Note in global form) may be
              surrendered in exchange therefor, at each office or agency
              maintained by the Company pursuant to Section 5.2 and the
              Trustee or such authenticating agent shall authenticate and
              deliver in exchange for such temporary Notes an equal
              aggregate principal amount of definitive Notes.  Such
              exchange shall be made by the Company at its own expense and
              without any charge therefor.  Until so exchanged, the
              temporary Notes shall in all respects be entitled to the same
              benefits and subject to the same limitations under this
              Indenture as definitive Notes authenticated and delivered
              hereunder.

                   Section 2.8 CANCELLATION OF NOTES PAID, ETC.  All Notes
              surrendered for the purpose of payment, redemption,
              repurchase, conversion, exchange or registration of transfer,
              shall, if surrendered to the Company or any paying agent or
              any Note registrar or any conversion agent, be surrendered to
              the Trustee and promptly canceled by it, or, if surrendered
              to the Trustee, shall be promptly canceled by it (provided
              that in the case of any Note or portion thereof submitted for
              repurchase, the Trustee shall not cancel such Note or portion
              thereof until after the Repurchase Date), and no Notes shall
              be issued in lieu thereof except as expressly permitted by
              any of the provisions of this Indenture, provided that any
              Note or portion thereof surrendered for repurchase shall only
              be cancelled at such time as such Note or portion thereof has
              been repurchased pursuant to Article XVI hereof.  The Trustee
              shall destroy canceled Notes (unless the Company directs it
              to do otherwise) and, after such destruction, shall, if
              requested by the Company, deliver a certificate of such
              destruction to the Company.  If the Company shall acquire any
              of the Notes, such acquisition shall not operate as a
              redemption or satisfaction of the indebtedness represented by
              such Notes unless and until the same are delivered to the
              Trustee for cancellation.  



                                     ARTICLE III

                                 REDEMPTION OF NOTES


                   Section 3.1 REDEMPTION PRICES.  The Company may not
              redeem the Notes prior to March 15, 1999.  At any time on or
              after March 15, 1999, the Company may, at its option, redeem
              all or from time to time any part of the Notes on any date
              prior to maturity, upon notice as set forth in Section 3.2,
              and at the optional redemption prices set forth in the form
              of Note attached as Exhibit A hereto,


                                        -15-





              together with accrued interest to, but excluding, the date
              fixed for redemption; provided that if the date fixed for
              redemption is March 15 or September 15, then the interest
              payable on such date shall be paid to the holder of record of
              the Note on the next preceding March 1 or September 1,
              respectively.

                   Section 3.2 NOTICE OF REDEMPTION: SELECTION OF NOTES.
              In case the Company shall desire to exercise the right to
              redeem all or, as the case may be, any part of the Notes
              pursuant to Section 3.1, it shall fix a date for redemption
              and it or, at its request, the Trustee in the name of and at
              the expense of the Company, shall mail or cause to be mailed
              a notice of such redemption at least 30 and not more than 60
              days prior to the date fixed for redemption to the holders of
              Notes so to be redeemed as a whole or in part at their most
              recent available addresses as the same appear on the Note
              register (provided that if the Company shall give such
              notice, it shall also give written notice, and written notice
              of the Notes to be redeemed, to the Trustee).  Such mailing
              shall be by first class mail. The notice if mailed in the
              manner herein provided shall be conclusively presumed to have
              been duly given, whether or not the holder receives such
              notice.  In any case, failure to give such notice by mail or
              any defect in the notice to the holder of any Note designated
              for redemption as a whole or in part shall not affect the
              validity of the proceedings for the redemption of any other
              Note.

                   Each such notice of redemption shall specify the
              aggregate principal amount of Notes to be redeemed, the date
              fixed for redemption, the redemption price at which Notes are
              to be redeemed, the place or places of payment, that payment
              will be made upon presentation and surrender of such Notes,
              that interest accrued to, but excluding, the date fixed for
              redemption will be paid as specified in said notice, and that
              on and after said date interest thereon or on the portion
              thereof to be redeemed will cease to accrue.  Such notice
              shall also state the current Conversion Price and the date on
              which the right to convert such Notes or portions thereof
              into Common Stock will expire.  If fewer than all the Notes
              are to be redeemed, the notice of redemption shall identify
              the Notes to be redeemed.  In case any Note is to be redeemed
              in part only, the notice of redemption shall state the
              portion of the principal amount thereof to be redeemed and
              shall state that on and after the date fixed for redemption,
              upon surrender of such Note, a new Note or Notes in principal
              amount equal to the unredeemed portion thereof will be
              issued.

                   On or prior to the redemption date specified in the
              notice of redemption given as provided in this Section 3.2,
              the Company will deposit with the Trustee or with one or more
              paying agents (or, if the Company is acting as its own paying
              agent, set aside, segregate and hold in trust as provided in
              Section 5.4) an amount


                                        -16-





              of money sufficient to redeem on the redemption date all the
              Notes (or portions thereof) so called for redemption (other
              than those theretofore surrendered for conversion into Common
              Stock) at the appropriate redemption price, together with
              accrued interest to, but excluding, the date fixed for
              redemption; provided that if such payment is made on the
              redemption date it must be received by the Trustee or paying
              agent, as the case may be, by 10:00 a.m.  New York City time,
              on such date.  If any Note called for redemption is converted
              pursuant hereto, any money deposited with the Trustee or any
              paying agent or so segregated and held in trust for the
              redemption of such Note shall be paid to the Company upon its
              written request, or, if then held by the Company, shall be
              discharged from such trust.  If fewer than all the Notes are
              to be redeemed, the Company will give the Trustee written
              notice in the form of an Officers' Certificate not fewer than
              forty-five (45) days (or such shorter period of time as may
              be acceptable to the Trustee) prior to the redemption date as
              to the aggregate principal amount of Notes to be redeemed.

                   If fewer than all the Notes are to be redeemed, the
              Trustee shall select the Notes or portions thereof to be
              redeemed (in principal amounts of $1,000 or integral
              multiples thereof), by lot or, in its discretion, on a pro
              rata basis with such adjustments up to $1,000 in order to
              maintain the minimum denominations of the Notes.  If any Note
              selected for partial redemption is converted in part after
              such selection, the converted portion of such Note shall be
              deemed (so far as may be) to be the portion to be selected
              for redemption.  The Notes (or portions thereof) so selected
              shall be deemed duly selected for redemption for all purposes
              hereof, notwithstanding that any such Note is converted as a
              whole or in part before the mailing of the notice of
              redemption.

                   Upon any redemption of less than all Notes, the Company
              and the Trustee may (but need not) treat as outstanding any
              Notes surrendered for conversion during the period of fifteen
              (15) days next preceding the mailing of a notice of
              redemption and may (but need not) treat as outstanding any
              Note authenticated and delivered during such period in
              exchange for the unconverted portion of any Note converted in
              part during such period.

                   Section 3.3 PAYMENT OF NOTES CALLED FOR REDEMPTION.  If
              notice of redemption has been given as above provided, the
              Notes or portion of Notes with respect to which such notice
              has been given shall, unless converted into Common Stock
              pursuant to the terms hereof, become due and payable on the
              redemption date and at the place or places stated in such
              notice at the applicable redemption price, together with
              interest accrued to (but excluding) the date fixed for
              redemption, and on and after said date (unless the Company
              shall default in the payment of such


                                        -17-





              Notes at the redemption price, together with interest accrued
              to, but excluding, said date) interest on the Notes or
              portion of Notes so called for redemption shall cease to
              accrue and such Notes shall cease after the close of business
              on the second Business Day next preceding the date fixed for
              redemption to be convertible into Common Stock and, except as
              provided in Sections 8.5 and 13.4, to be entitled to any
              benefit or security under this Indenture, and the holders
              thereof shall have no right in respect of such Notes except
              the right to receive the redemption price thereof and unpaid
              interest to (but excluding) the date fixed for redemption.
              On presentation and surrender of such Notes at a place of
              payment in said notice specified, the said Notes or the
              specified portions thereof shall be paid and redeemed by the
              Company at the applicable redemption price, together with
              interest accrued thereon to (but excluding) the date fixed
              for redemption; provided that, if the applicable redemption
              date is an interest payment date, the semi-annual payment of
              interest becoming due on such date shall be payable to the
              holders of such Notes registered as such on the relevant
              record date instead of the holders surrendering such Notes
              for redemption on such date.

                   Upon presentation of any Note redeemed in part only, the
              Company shall execute and the Trustee shall authenticate and
              deliver to the holder thereof, at the expense of the Company,
              a new Note or Notes, of authorized denominations, in
              principal amount equal to the unredeemed portion of the Notes
              so presented.

                  Notwithstanding the foregoing, the Trustee shall not pay
              the redemption price of any Notes or mail any notice of
              optional redemption during the continuance of a default in
              payment of interest or premium on the Notes or of any Event
              of Default of which, in the case of any Event of Default
              other than under Sections 7.1(a) or 7.1(b), a Responsible
              Officer of the Trustee has knowledge.  If any Note called for
              redemption shall not be so paid upon surrender thereof for
              redemption, the principal and premium, if any, shall, until
              paid or duly provided for, bear interest from the date fixed
              for redemption at the rate borne by the Note and such Note
              shall remain convertible into Common Stock until the
              principal and premium, if any, shall have been paid or duly
              provided for.  

                   Section 3.4 CONVERSION ARRANGEMENT ON CALL FOR
              REDEMPTION.  In connection with any redemption of Notes, the
              Company may arrange for the purchase and conversion of any
              Notes by an agreement with one or more investment bankers or
              other purchasers to purchase such Notes by paying to the
              Trustee in trust for the Noteholders, on or before the date
              fixed for redemption, an amount not less than the applicable
              redemption price, together with interest accrued to (but
              excluding) the date fixed for redemption, of such Notes.
              Notwithstanding anything to the contrary contained


                                        -18-





              in this Article III, the obligation of the Company to pay the
              redemption price of such Notes, together with interest
              accrued to (but excluding) the date fixed for redemption,
              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, a copy of which will be filed with
              the Trustee prior to the date fixed for redemption, any Notes
              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 XV) surrendered by such purchasers for
              conversion, all as of immediately prior to the close of
              business on the date fixed for redemption (and the right to
              convert any such Notes shall be extended through such time),
              subject to payment of the above amount as aforesaid.  At the
              direction of the Company, the Trustee shall hold and dispose
              of any such amount paid to it in the same manner as it would
              monies deposited with it by the Company for the redemption of
              Notes.  Without the Trustee's prior written consent, no
              arrangement between the Company and such purchasers for the
              purchase and conversion of any Notes 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 Notes between the Company
              and such purchasers to which the Trustee has not consented in
              writing, including the costs and expenses, including
              reasonable legal fees, incurred by the Trustee 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 IV

                                  SUBORDINATION OF NOTES


                   Section 4.1 AGREEMENT OF SUBORDINATION.  The Company
              covenants and agrees, and each holder of Notes issued
              hereunder by his acceptance thereof likewise covenants and
              agrees, that all Notes shall be issued subject to the
              provisions of this Article IV; and each Person holding any
              Note, whether upon original issue or upon transfer,
              assignment or exchange thereof, accepts and agrees to be
              bound by such provisions.

                   The payment of the principal of, premium, if any, and
              interest on all Notes (including, but not limited to, the
              redemption price with respect to the Notes called for
              redemption


                                        -19-





              in accordance with Section 3.2 or submitted for repurchase in
              accordance with Section 16.2, as the case may be, as provided
              in the Indenture) issued hereunder shall, to the extent and
              in the manner hereinafter set forth, be subordinated and
              subject in right of payment to the prior payment in full of
              all Senior Indebtedness, whether outstanding at the date of
              this Indenture or thereafter incurred.

                   No provision of this Article IV shall prevent the
              occurrence of any default or Event of Default hereunder.

                   Section 4.2 PAYMENTS TO NOTEHOLDERS.  No payment shall
              be made with respect to the principal of, or premium, if any,
              or interest on the Notes (including, but not limited to, the
              redemption price or the Repurchase Price with respect to the
              Notes to be called for redemption in accordance with Section
              3.2 or submitted for repurchase in accordance with Section
              16.2, as the case may be, as provided in the Indenture),
              except payments and distributions made by the Trustee as
              permitted by the first or second paragraph of Section 4.5,
              if:

                             (1) a default in the payment of principal,
              premium, interest, rent or other obligations due on any
              Senior Indebtedness occurs and is continuing (or, in the case
              of Senior Indebtedness for which there is a period of grace,
              in the event of such a default that continues beyond the
              period of grace, if any, specified in the instrument or lease
              evidencing such Senior Indebtedness), unless and until such
              default shall have been cured or waived or shall have ceased
              to exist; or

                             (2) a default, other than a payment default,
              on any Designated Senior Indebtedness occurs and is
              continuing that then permits holders of such Designated
              Senior Indebtedness to accelerate its maturity and the
              Trustee receives a notice of the default (a "Payment Blockage
              Notice") from a Person who may give it pursuant to Section
              4.5 hereof.  If the Trustee receives any Payment Blockage
              Notice pursuant to clause (2) above, no subsequent Payment
              Blockage Notice shall be effective for purposes of this
              Section unless and until (A) at least 365 days shall have
              elapsed since the effectiveness of the immediately prior
              Payment Blockage Notice, and (B) all scheduled payments of
              principal, premium, if any, and interest on the Notes that
              have come due have been paid in full in cash.  No nonpayment
              default that existed or was continuing on the date of
              delivery of any Payment Blockage Notice to the Trustee shall
              be, or be made, the basis for a subsequent Payment Blockage
              Notice.

              The Company may and shall resume payments on and
              distributions in respect of the Notes upon the earlier of:


                                        -20-





                        (x)  the date upon which the default is cured or
                             waived,
                             or 

                   (y)  in the case of a default referred to in clause (2) 
                        above, 179 days pass after notice is received if
                        the maturity of such Designated Senior Indebtedness
                        has not been accelerated, unless this Article IV
                        otherwise prohibits the payment or distribution at
                        the time of such payment or distribution.

         Upon any payment by the Company, or distribution of assets of the
         Company of any kind or character, whether in cash, property or
         securities, to creditors upon any dissolution or winding-up or
         liquidation or reorganization of the Company, whether voluntary or
         involuntary or in bankruptcy, insolvency, receivership or other
         proceedings, all amounts due or to become due upon all Senior
         Indebtedness shall first be paid in full in cash or other payment
         satisfactory to the holders of such Senior Indebtedness, or
         payment thereof in accordance with its terms shall be provided for
         in cash or other payment satisfactory to the holders of such
         Senior Indebtedness before any payment is made on account of the
         principal of, premium, if any, or interest on the Notes (except
         payments made pursuant to Article XIII from monies deposited with
         the Trustee pursuant thereto prior to commencement of proceedings
         for such dissolution, winding-up, liquidation or reorganization);
         and upon any such dissolution or winding-up or liquidation or
         reorganization of the Company or bankruptcy, insolvency,
         receivership or other proceeding, any payment by the Company, or
         distribution of assets of the Company of any kind or character,
         whether in cash, property or securities, to which the holders of
         the Notes or the Trustee would be entitled, except for the
         provision of this Article IV, shall (except as aforesaid) be paid
         by the Company or by any receiver, trustee in bankruptcy,
         liquidating trustee, agent or other Person making such payment or
         distribution, or by the holders of the Notes or by the Trustee
         under this Indenture if received by them or it, directly to the
         holders of Senior Indebtedness (pro rata to such holders on the
         basis of the respective amounts of Senior Indebtedness held by
         such holders, or as otherwise required by law or a court order) or
         their representative or representatives, or to the trustee or
         trustees under any indenture pursuant to which any instruments
         evidencing any Senior Indebtedness may have been issued, as their
         respective interests may appear, to the extent necessary to pay
         all Senior Indebtedness in full, in cash or other payment
         satisfactory to the holders of such Senior Indebtedness, after
         giving effect to any concurrent payment or distribution to or for
         the holders of Senior Indebtedness, before any payment or
         distribution or provision therefor is made to the holders of the
         Notes or to the Trustee.


                                        -21-





              For purposes of this Article IV, the words, "cash, property
         or securities" shall not be deemed to include 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, the payment of which is
         subordinated at least to the extent provided in this Article IV
         with respect to the Notes to the payment of all Senior
         Indebtedness which may at the time be outstanding; provided that
         (i) the Senior Indebtedness is assumed by the new corporation, if
         any, resulting from any reorganization or readjustment, and (ii)
         the rights of the holders of Senior Indebtedness (other than
         leases which are not assumed by the Company or the new
         corporation, as the case may be) are not, without the consent of
         such holders, altered by such reorganization or readjustment.  The
         consolidation of the Company with, or the merger of the Company
         into, another corporation or the liquidation or dissolution of the
         Company following the conveyance or transfer of its property as an
         entirety, or substantially as an entirety, to another corporation
         upon the terms and conditions provided for in Article XII shall
         not be deemed a dissolution, winding-up, liquidation or
         reorganization for the purposes of this Section 4.2 if such other
         corporation shall, as a part of such consolidation, merger,
         conveyance or transfer, comply with the conditions stated in
         Article XII.  

              In the event of the acceleration of the Notes because of an
         Event of Default, no payment or distribution shall be made to the
         Trustee or any holder of Notes in respect of the principal of,
         premium, if any, or interest on the Notes (including, but not
         limited to, the redemption price with respect to the Notes called
         for redemption in accordance with Section 3.2 or submitted for
         repurchase in accordance with Section 16.2, as the case may be, as
         provided in the Indenture), except payments and distributions made
         by the Trustee as permitted by the first or second paragraph of
         Section 4.5, until all Senior Indebtedness has been paid in full
         in cash or other payment satisfactory to the holders of Senior
         Indebtedness or such acceleration is rescinded in accordance with
         the terms of this Indenture.  If payment of the Notes is
         accelerated because of an Event of Default, the Company shall
         promptly notify holders of Senior Indebtedness of the
         acceleration.

              In the event that, notwithstanding the foregoing provisions,
         any payment or distribution of assets of the Company of any kind
         or character, whether in cash, property or securities (including,
         without limitation, by way of setoff or otherwise), prohibited by
         the foregoing, shall be received by the Trustee or the holders of
         the Notes before all Senior Indebtedness is paid in full in cash
         or other payment satisfactory to the holders of such Senior
         Indebtedness, or provision is made for such payment thereof in


                                        -22-





         accordance with its terms in cash or other payment satisfactory to
         the holders of such Senior Indebtedness, such payment or
         distribution shall be held in trust for the benefit of and shall
         be paid over or delivered to the holders of Senior Indebtedness or
         their representative or representatives, or to the trustee or
         trustees under any indenture pursuant to which any instruments
         evidencing any Senior Indebtedness may have been issued, as their
         respective interests may appear, as calculated by 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 cash or other payment satisfactory to the holders of such
         Senior Indebtedness, after giving effect to any concurrent payment
         or distribution to or for the holders of such Senior Indebtedness.

              Nothing in this Section 4.2 shall apply to claims of, or
         payments to, the Trustee under or pursuant to Section 8.6.  This
         Section 4.2 shall be subject to the further provisions of Section
         4.5.

              Section 4.3 SUBROGATION OF NOTES.  Subject to the payment in
         full of all Senior Indebtedness, the rights of the holders of the
         Notes shall be subrogated to the extent of the payments or
         distributions made to the holders of such Senior Indebtedness
         pursuant to the provisions of this Article IV (equally and ratably
         with the holders of all indebtedness of the Company which by its
         express terms is subordinated to other indebtedness of the Company
         to substantially the same extent as the Notes are subordinated and
         is entitled to like rights of subrogation) to the rights of the
         holders of Senior Indebtedness to receive payments or
         distributions of cash, property or securities of the Company
         applicable to the Senior Indebtedness until the principal,
         premium, if any, and interest on the Notes shall be paid in full;
         and, for the purposes of such subrogation, no payments or
         distributions to the holders of the Senior Indebtedness of any
         cash, property or securities to which the holders of the Notes or
         the Trustee would be entitled except for the provisions of this
         Article IV, and no payments pursuant to the provisions of this
         Article IV, to or for the benefit of the holders of Senior
         Indebtedness by holders of the Notes or the Trustee, shall, as
         between the Company, its creditors other than holders of Senior
         Indebtedness, and the holders of the Notes, be deemed to be a
         payment by the Company to or on account of the Notes; and no
         payments or distributions of cash, property or securities to or
         for the benefit of the holders of the Notes pursuant to the
         subrogation provisions of this Article IV, which would otherwise
         have been paid to the holders of Senior Indebtedness shall be
         deemed to be a payment by the Company to or for the account of the
         Notes.  It is understood that the provisions of this Article IV
         are and are intended solely for the purposes of defining the



                                        -23-





         relative rights of the holders of the Notes, on the one hand, and
         the holders of the Senior Indebtedness, on the other hand.

              Nothing contained in this Article IV or elsewhere in this
         Indenture or in the Notes is intended to or shall impair, as among
         the Company, its creditors other than the holders of Senior
         Indebtedness, and the holders of the Notes, the obligation of the
         Company, which is absolute and unconditional, to pay to the
         holders of the Notes the principal of (and premium, if any) and
         interest on the Notes as and when the same shall become due and
         payable in accordance with their terms, or is intended to or shall
         affect the relative rights of the holders of the Notes and
         creditors of the Company other than the holders of the Senior
         Indebtedness, nor shall anything herein or therein prevent the
         Trustee or the holder of any Note from exercising (subject to the
         provisions hereof) all remedies otherwise permitted by applicable
         law upon default under this Indenture, subject to the rights, if
         any, under this Article IV of the holders of Senior Indebtedness
         in respect of cash, property or securities of the Company received
         upon the exercise of any such remedy.

              Upon any payment or distribution of assets of the Company
         referred to in this Article IV, the Trustee, subject to the
         provisions of Section 8.1, and the holders of the Notes shall be
         entitled to rely upon any order or decree made by any court of
         competent jurisdiction in which such bankruptcy, dissolution,
         winding-up, liquidation or reorganization proceedings are pending,
         or a certificate of the receiver, trustee in bankruptcy,
         liquidating trustee, agent or other person making such payment or
         distribution, delivered to the Trustee or to the holders of the
         Notes, for the purpose of ascertaining the persons entitled to
         participate in such distribution, the holders of the Senior
         Indebtedness and other indebtedness of the Company, the amount
         thereof or payable thereon and all other facts pertinent thereto
         or to this Article IV.

              Section 4.4 AUTHORIZATION TO EFFECT SUBORDINATION.  Each
         holder of a Note by the holder's acceptance thereof authorizes and
         directs the Trustee on the holder's behalf to take such action as
         may be necessary or appropriate to effectuate the subordination as
         provided in this Article IV and appoints the Trustee to act as the
         holder's attorney-in-fact for any and all such purposes.  If the
         Trustee does not file a proper proof of claim or proof of debt in
         the form required in any proceeding referred to in the third
         paragraph of Section 7.2 hereof at least 30 days before the
         expiration of the time to file such claim, the holders of any
         Senior Indebtedness or their representatives are hereby authorized
         to file an appropriate claim for and on behalf of the holders of
         the Notes.



                                        -24-





              Section 4.5 NOTICE TO TRUSTEE.  The Company shall give prompt
         written notice in the form of an Officers' Certificate to a
         Responsible Officer of the Trustee and to any paying agent of any
         fact known to the Company which would prohibit the making of any
         payment of monies to or by the Trustee or any paying agent in
         respect of the Notes pursuant to the provisions of this Article
         IV. Notwithstanding the provisions of this Article IV or any other
         provision of this Indenture, the Trustee shall not be charged with
         knowledge of the existence of any facts which would prohibit the
         making of any payment of monies to or by the Trustee in respect of
         the Notes pursuant to the provisions of this Article IV, unless
         and until a Responsible Officer of the Trustee shall have received
         written notice thereof at the Corporate Trust Office from the
         Company or a holder or holders of Senior Indebtedness or from any
         trustee thereof; and before the receipt of any such written
         notice, the Trustee, subject to the provisions of Section 8.1,
         shall be entitled in all respects to assume that no such facts
         exist; provided that if on a date not fewer than two Business Days
         prior to the date upon which by the terms hereof any such monies
         may become payable for any purpose (including, without limitation,
         the payment of the principal of, or premium, if any, or interest
         on any Note) the Trustee shall not have received, with respect to
         such monies, the notice provided for in this Section 4.5, then,
         anything herein contained to the contrary notwithstanding, the
         Trustee shall have full power and authority to receive such monies
         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 prior date. 

              Notwithstanding anything in this Article IV to the contrary,
         nothing shall prevent (a) any payment by the Company or the
         Trustee to the Trustee or Noteholders of amounts in connection
         with a redemption of Notes (including a redemption pursuant to
         Section 3.5) if (i) notice of such redemption has been given
         pursuant to Article III prior to the receipt by the Trustee of
         written notice as aforesaid, and (ii) such notice of redemption is
         given not earlier than sixty (60) days before the redemption date
         or (b) any payment by the Trustee to the Noteholders of monies
         deposited with it pursuant to Section 13.1, and any such payment
         shall not be subject to the provisions of Section 4.1 or 4.2.

              The Trustee, subject to the provisions of Section 8.1, shall
         be entitled to rely on the delivery to it of a written notice by a
         person representing himself to be a holder of Senior Indebtedness
         (or a trustee on behalf of such holder) to establish that such
         notice has been given by a holder of Senior Indebtedness or a
         trustee on behalf of any such holder or holders.  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


                                        -25-





         pursuant to this Article IV, the Trustee may request such person
         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 any other facts pertinent to the
         rights of such person under this Article IV, and if such evidence
         is not furnished the Trustee may defer any payment to such person
         pending judicial determination as to the right of such person to
         receive such payment.

              Section 4.6 TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.  The
         Trustee in its individual capacity shall be entitled to all the
         rights set forth in this Article IV in respect of any Senior
         Indebtedness at any time held by it, to the same extent as any
         other holder of Senior Indebtedness, and nothing in Section 8.13
         or elsewhere in this Indenture shall deprive the Trustee of any of
         its rights as such holder.

              With respect to the holders of Senior Indebtedness, the
         Trustee undertakes to perform or to observe only such of its
         covenants and obligations as are specifically set forth in this
         Article IV, and no implied covenants or obligations with respect
         to the holders of Senior Indebtedness shall be read into this
         Indenture against the Trustee.  The Trustee shall not be deemed to
         owe any fiduciary duty to the holders of Senior Indebtedness and,
         subject to the provisions of Section 8.1, the Trustee shall not be
         liable to any holder of Senior Indebtedness if it shall pay over
         or deliver to holders of Notes, the Company or any other person
         money or assets to which any holder of Senior Indebtedness shall
         be entitled by virtue of this Article IV or otherwise.

              Section 4.7 NO IMPAIRMENT OF SUBORDINATION.  No right of any
         present or future holder of any Senior Indebtedness 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 which any such holder may have or otherwise
         be charged with.

              Section 4.8 CERTAIN CONVERSIONS DEEMED PAYMENT.  For the
         purposes of this Article IV only, (1) the issuance and delivery of
         junior securities upon conversion of Notes in accordance with
         Article XV shall not be deemed to constitute a payment or
         distribution on account of the principal of (or premium, if any)
         or interest on Notes or on account of the purchase or other
         acquisition of Notes, and (2) the payment, issuance or delivery of
         cash, property or securities (other than junior securities) upon
         conversion of a Note shall be deemed to constitute payment on


                                        -26-





         account of the principal of such Note.  For the purposes of this
         Section 4.8, the term "junior securities" means (a) shares of any
         stock of any class of the Company, or (b) securities of the
         Company which are subordinated in right of payment to all Senior
         Indebtedness which may be outstanding at the time of issuance or
         delivery of such securities to substantially the same extent as,
         or to a greater extent than, the Notes are so subordinated as
         provided in this Article.  Nothing contained in this Article IV or
         elsewhere in this Indenture or in the Notes is intended to or
         shall impair, as among the Company, its creditors other than
         holders of Senior Indebtedness and the Noteholders, the right,
         which is absolute and unconditional, of the Holder of any Note to
         convert such Note in accordance with Article XV.

              Section 4.9 ARTICLE APPLICABLE TO PAYING AGENTS.  If at any
         time any paying agent other than the Trustee shall have been
         appointed by the Company and be then acting hereunder, the term
         "Trustee" as used in this Article shall (unless the context
         otherwise requires) be construed as extending to and including
         such paying agent within its meaning as fully for all intents and
         purposes as if such paying agent were named in this Article in
         addition to or in place of the Trustee; provided, however, that
         the first paragraph of Section 4.5 shall not apply to the Company
         or any Affiliate of the Company if it or such Affiliate acts as
         paying agent.

              Section 4.10 SENIOR INDEBTEDNESS ENTITLED TO RELY. The
         holders of Senior Indebtedness (including, without limitation,
         Designated Senior Indebtedness) shall have the right to rely upon
         this Article IV, and no amendment or modification of the
         provisions contained herein shall diminish the rights of such
         holders unless such holders shall have agreed in writing thereto.


                                      ARTICLE V

                        PARTICULAR COVENANTS OF THE COMPANY

               Section 5.1 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.  The
         Company covenants and agrees that it will duly and punctually pay
         or cause to be paid the principal of and premium, if any, and
         interest on each of the Notes at the places, at the respective
         times and in the manner provided herein and in the Notes.  Each
         installment of interest on the Notes due on any semi-annual
         interest payment date may be paid by mailing checks for the
         interest payable to or upon the written order of the holders of
         Notes entitled thereto as they shall appear on the registry books
         of the Company; provided, that; with respect to any holder of
         Notes with an aggregate principal amount equal to or in excess of
         $5,000,000, at the request of such holder in writing to the


                                        -27-





         Company (who shall then furnish notice to such effect to the
         Trustee), interest on such holder's Notes shall be paid by wire
         transfer (the cost of such wire transfer to be borne by the
         Company) in immediately available funds in accordance with the
         wire transfer instructions supplied by such holder to the Trustee
         and paying agent (if different from the Trustee).

              Section 5.2 MAINTENANCE OF OFFICE OR AGENCY.  The Company
         will maintain in the Borough of Manhattan, The City of New York or
         in Boston, Massachusetts, an office or agency where the Notes may
         be surrendered for registration of transfer or exchange or for
         presentation for payment or for conversion or redemption and where
         notices and demands to or upon the Company in respect of the Notes
         and this Indenture may be served.  The Company will give prompt
         written notice to the Trustee of the location, and any change in
         the location, of such office or agency not designated or appointed
         by the Trustee.  If at any time the Company shall fail to maintain
         any such required office or agency or shall fail to furnish the
         Trustee with the address thereof, such presentations, surrenders,
         notices and demands may be made or served at the Corporate Trust
         Office or agency of the Trustee in the Borough of Manhattan, The
         City of New York. 

              The Company may also from time to time designate one or more
         other offices or agencies where the Notes may be presented or
         surrendered for any or all such purposes and may from time to time
         rescind such designations; provided that no such designation or
         rescission shall in any manner relieve the Company of its
         obligation to maintain an office or agency in the Borough of
         Manhattan, The City of New York for such purposes.  The Company
         will give prompt written notice to the holders of any such
         designation or rescission and of any change in the location of any
         such other office or agency.  

              The Company hereby initially designates the Trustee as paying
         agent, Note registrar and conversion agent, and each of the
         Corporate Trust Office of the Trustee and the office or agency of
         the Trustee in the Borough of Manhattan, The City of New York
         (which shall initially be State Street Bank and Trust Company,
         N.A., an affiliate of the Trustee) as one such office or agency of
         the Company for each of the aforesaid purposes.  

              The Trustee agrees to mail, or cause to be mailed, the
         notices set forth in Section 8.10(a) and the third paragraph of
         Section 8.11. 

              Section 5.3 APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S
         OFFICE. The Company, whenever necessary to avoid or fill a vacancy
         in the office of Trustee, will appoint, in the manner provided in



                                        -28-





         Section 8.10, a Trustee, so that there shall at all times be a
         Trustee hereunder.

              Section 5.4 PROVISIONS AS TO PAYING AGENT.

                   (a) If the Company shall appoint a paying agent other
         than the Trustee, or if the Trustee shall appoint such a paying
         agent, it will cause such paying agent to execute and deliver to
         the Trustee an instrument in which such agent shall agree with the
         Trustee, subject to the provisions of this Section 5.4:

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

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

                        (3) that at any time during the continuance of an
         Event of Default, upon request of the Trustee, it will forthwith
         pay to the Trustee all sums so held in trust.

                   The Company shall, on or before each due date of the
         principal of, premium, if any, or interest on the Notes, deposit
         with the paying agent in immediately available funds a sum
         sufficient to pay such principal, premium, if any, or interest,
         and (unless such paying agent is the Trustee) the Company will
         promptly notify the Trustee of any failure to take such action;
         provided that if such deposit is made on the due date, 
         such deposit shall be received by the paying agent by 10:00 a.m.
         New York City time, on such date.

                   (b) If the Company shall act as its own paying agent, it
         will, on or before each due date of the principal of, premium, if
         any, or interest on the Notes, set aside, segregate and hold in
         trust for the benefit of the holders of the Notes a sum sufficient
         to pay such principal, premium, if any, or interest so becoming
         due and will notify the Trustee of any failure to take such action
         and of any failure by the Company (or any other obligor under the
         Notes) to make any payment of the principal of, premium, if any,
         or interest on the Notes when the same shall become due and
         payable.
                   (c) Anything in this Section 5.4 to the contrary
          notwithstanding, the Company may, at any time, for the purpose of
         obtaining a satisfaction and discharge of this Indenture, or for
         any other reason, pay or cause to be paid to the Trustee all sums


                                        -29-





         held in trust by the Company or any paying agent hereunder as
         required by this Section 5.4, such sums to be held by the Trustee
         upon the trusts herein contained and upon such payment by the
         Company or any paying agent to the Trustee, the Company or such
         paying agent shall be released from all further liability with
         respect to such sums.

                   (d) Anything in this Section 5.4 to the contrary
         notwithstanding, the agreement to hold sums in trust as provided
         in this Section 5.4 is subject to Sections 13.3 and 13.4.

              Section 5.5 CORPORATE EXISTENCE.  Subject to Article XII, the
         Company will do or cause to be done all things necessary to
         preserve and keep in full force and effect its corporate
         existence.

              Section 5.6 STAY, EXTENSION AND USURY LAWS.  The Company
         covenants (to the extent that it may lawfully do so) that it shall
         not at any time insist upon, plead, or in any manner whatsoever
         claim or take the benefit or advantage of, any stay, extension or
         usury law or other law which would prohibit or forgive the Company
         from paying all or any portion of the principal of or interest on
         the Notes as contemplated herein, wherever enacted, now or at any
         time hereafter in force, or which may affect the covenants or the
         performance of this Indenture and the Company (to the extent it
         may lawfully do so) hereby expressly waives all benefit or
         advantage of any such law, and covenants that it will not, by
         resort to any such law, hinder, delay or impede the execution of
         any power herein granted to the Trustee, but will suffer and
         permit the execution of every such power as though no such law has
         been enacted.

              Section 5.7 COMPLIANCE CERTIFICATE.  The Company shall
         deliver to the Trustee within 120 days after the end of each
         fiscal year of the Company (beginning with the fiscal year ending
         on December 31, 1996) an Officers' Certificate stating whether or
         not the signers know of any Event of Default that occurred during
         such period.  If such signers know of any Event of Default that
         occurred during such period, such Officers' Certificate shall
         describe the Event of Default and its status.

               Section 6.1 NOTEHOLDERS' LISTS.  The Company covenants and
         agrees that it will furnish or cause to be furnished to the


                                        -30-

         March 1 and September 1 in each year beginning with September 1,
         1996, and at such other times as the Trustee may request in
         writing, within thirty (30) days after receipt by the Company of
         any such request (or such lesser time as the Trustee may
         reasonably request in order to enable it to timely provide any
         notice to be provided by it hereunder), a list in such form as the
         Trustee may reasonably require of the names and addresses of the
         holders of Notes as of a date not more than fifteen (15) days (or
         such other date as the Trustee may reasonably request in order to
         so provide any such notices) prior to the time such information is
         furnished, except that no such list need be furnished so long as
         the Trustee is acting as Note registrar.

              Section 6.2 PRESERVATION AND DISCLOSURE OF LISTS.

                   (a) The Trustee shall preserve, in as current a form as

         Trustee, shall be as provided by the Trust Indenture Act.

                   (c) Every Noteholder, by receiving and holding the same,
         agrees with the Company and the Trustee that neither the Company
         nor the Trustee nor any agent of either of them shall be held
         accountable by reason of any disclosure of information as to names

         Indenture Act.

              Section 6.3 REPORTS BY TRUSTEE.

         shall also transmit all reports as required by Section 313(b)(2)
         of the Trust Indenture Act to such holders of Notes.  The Trustee
         shall transmit all such reports in such manner as is required 
         by Section 313(c) of the Trust Indenture Act. 




                                        -31-





              (b) A copy of such report shall, at the time of such
         transmission to holders of Notes, be filed by the Trustee with
         each stock exchange and automated quotation system upon which the
         Notes are listed and with the Company.  The Company will notify
         the Trustee within a reasonable time when the Notes are listed on
         any stock exchange and automated quotation system.

              Section 6.4 REPORTS BY COMPANY.  The Company shall file with

         and such summaries thereof, as may be required pursuant to the
         Trust Indenture Act at the times and in the manner provided
         pursuant to such Act; provided that any such information,
         documents or reports required to be filed with the Commission
         pursuant to Section 13 or 15(d) of the Exchange Act shall be filed
         with the Trustee within 15 days after the same is so required to

               Section 7.1 EVENTS OF DEFAULT. In case one or more of the
         following Events of Default (whatever the reason for such Event of
         Default and whether it shall be voluntary or involuntary or be
         effected by operation of law or pursuant to any judgment, decree
         or order of any court or any order, rule or regulation of any
         administrative or governmental body) shall have occurred and be
         continuing:

                   (a) default in the payment of any installment of
         interest upon  any of the Notes as and when the same shall become
         due and payable, and continuance of such default for a period of
         thirty (30) days, whether or not such payment is permitted under
         Article IV hereof; or

                   (b) default in the payment of the principal of or
         premium, if any, on any of the Notes as and when the same shall

         thirty (30) days, or a default by the Company or any such
         Subsidiary with respect to any Money Indebtedness, which default

         discharged or such acceleration having been cured, waived,
         rescinded or annulled within thirty (30) days after there shall
         have been given, by registered or certified mail, to the Company
         by the Trustee or to the Company and the Trustee by the holders of
         not less than 10% in aggregate principal amount of the Notes then
         outstanding a written notice specifying such default and requiring
         the Company to cause such Money Indebtedness to be discharged or
         cause such default to be cured or waived or such acceleration to
         be rescinded or annulled and stating that such notice is a "Notice
         of Default" hereunder; or

                   (d) failure on the part of the Company duly to observe
         or perform any other of the covenants or agreements on the part of
         the Company in the Notes or in this Indenture (other than a
         covenant or agreement a default in whose performance or whose
         breach is elsewhere in this Section 7.1 specifically dealt with)
         continued for a period of sixty (60) days after the date on which
         written notice of such failure, requiring the Company to remedy
         the same, shall have been given to the Company by the Trustee, or
         to the Company and a Responsible Officer of the Trustee by the
         holders of at least 25 percent in aggregate principal amount of
         the Notes at the time outstanding determined in accordance with
         Section 9.4; or 

                   (e) the Company shall commence a voluntary case or other 
         proceeding seeking liquidation, reorganization or other relief
         with respect to itself or its debts under any bankruptcy,
         insolvency or other similar law now or hereafter in effect or
         seeking the appointment of a trustee, receiver, liquidator,
         custodian or other similar official of it or any substantial part
         of its property, or shall consent to any such relief or to the
         appointment of or taking possession by any such official in an
         involuntary case or other proceeding commenced against it, or
         shall make a general assignment for the benefit of creditors, or
         shall fail generally to pay its debts as they become due; or

                   (f) an involuntary case or other proceeding shall be
         commenced against the Company seeking liquidation, reorganization
         or other relief with respect to it or its debts under any
         bankruptcy, insolvency or other similar law now or hereafter in
         effect or seeking the appointment of a trustee, receiver,
         liquidator, custodian or other similar official of it or any
         substantial part of its property, and such involuntary case or


                                        -33-





         other proceeding shall remain undismissed and unstayed for a
         period of ninety (90) consecutive days; then, and in each and
         every such case (other than an Event of Default specified in
         Section 7.1(e) or (f)), unless the principal of all of the Notes
         shall have already become due and payable, either the Trustee or
         the holders of not less than 25 percent in aggregate principal
         amount of the Notes then outstanding hereunder determined in
         accordance with Section 9.4, by notice in writing to the Company
         (and to the Trustee if given by Noteholders), may declare the
         principal of all the Notes and the interest accrued thereon to be
         due and payable immediately, and upon any such declaration the
         same shall become and shall be immediately due and payable,
         anything in this Indenture or in the Notes contained to the
         contrary notwithstanding.  In the event a declaration of
         acceleration because of an Event of Default specified in Section
         7.1(c) hereof has occurred and is continuing, such declaration of
         acceleration shall be automatically annulled if such default is
         cured or waived or the holders of the Debentures have rescinded
         their declaration of acceleration in respect of such indebtedness
         within 60 days thereof and the Trustee has received written notice
         of such cure, waiver or rescission and no other Event of Default
         described in Section 71(c) hereof has occurred that has not been
         cured or waived within 60 days of the declaration of such
         acceleration in respect thereof.  If an Event of Default specified
         in Section 7.1(e) or (f) occurs, the principal of all the Notes
         and the interest accrued thereon shall be immediately and
         automatically due and payable without necessity of further action.
         This provision, however, is subject to the conditions that if, at
         any time after the principal of the Notes shall have been so
         declared due and payable, and before any judgment or decree for
         the payment of the monies 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 Notes and the principal of and premium, if
         any, on any and all Notes which shall have become due otherwise
         than by acceleration (with interest on overdue installments of
         interest (to the extent that payment of such interest is
         enforceable under applicable law) and on such principal and
         premium, if any, at the rate borne by the Notes, to the date of
         such payment or deposit) and amounts due to the Trustee pursuant
         to Section 8.6, and if any and all defaults under this Indenture,
         other than the nonpayment of principal of and premium, if any, and
         accrued interest on Notes which shall have become due by
         acceleration, shall have been cured or waived pursuant to Section
         7.7 -- then and in every such case the holders of a majority in
         aggregate principal amount of the Notes then outstanding, by
         written notice to the Company and to the Trustee, may waive all
         defaults or Events of Default and rescind and annul such
         declaration and its consequences; but no such waiver or rescission
         and annulment shall extend to or shall affect any subsequent


                                        -34-





         default or Event of Default, or shall impair any right consequent
         thereon.  The Company shall notify a Responsible Officer of the
         Trustee, promptly upon becoming aware thereof, of any Event of
         Default.

              In case the Trustee shall have proceeded to enforce any right
         under this Indenture and such proceedings shall have been
         discontinued or abandoned because of such waiver or rescission and
         annulment or for any other reason or shall have been determined
         adversely to the Trustee, then and in every such case the Company,
         the holders of Notes, and the Trustee shall be restored
         respectively to their several positions and rights hereunder, and
         all rights, remedies and powers of the Company, the holders of
         Notes, and the Trustee shall continue as though no such proceeding
         had been taken.

              Section 7.2 PAYMENTS OF NOTES ON DEFAULT: SUIT THEREFOR. The
         Company covenants that (a) in case default shall be made in the
         payment of any installment of interest upon any of the Notes as
         and when the same shall become due and payable, and such default
         shall have continued for a period of thirty (30) days, or (b) in
         case default shall be made in the payment of the principal of or
         premium, if any, on any of the Notes as and when the same shall
         have become due and payable, whether at maturity of the Notes or
         in connection with any redemption or repurchase under this
         Indenture declaration or otherwise -- then, upon demand of the
         Trustee, the Company will pay to the Trustee, for the benefit of
         the holders of the Notes, the whole amount that then shall have
         become due and payable on all such Notes for principal and
         premium, if any, or interest, or both, as the case may be, with
         interest upon the overdue principal and premium, if any, and (to
         the extent that payment of such interest is enforceable under
         applicable law) upon the overdue installments of interest at the
         rate borne by the Notes; and, in addition thereto, such further
         amount as shall be sufficient to cover the costs and expenses of
         collection, including reasonable compensation to the Trustee, its
         agents, attorneys and counsel, and any expenses or liabilities
         incurred by the Trustee hereunder other than through its
         negligence or bad faith.  Until such demand by the Trustee, the
         Company may pay the principal of and premium, if any, and interest
         on the Notes to the registered holders, whether or not the Notes
         are overdue.

              In case the Company shall fail forthwith to pay such amounts
         upon such demand, the Trustee, in its own name and as trustee of
         an express trust, shall be entitled and empowered to institute any
         actions or proceedings at law or in equity for the collection of
         the sums so due and unpaid, and may prosecute any such action or
         proceeding to judgment or final decree, and may enforce any such
         judgment or final decree against the Company or any other obligor


                                        -35-





         on the Notes and collect in the manner provided by law out of the
         property of the Company or any other obligor on the Notes wherever
         situated the monies adjudged or decreed to be payable.

              In the case there shall be pending proceedings for the
         bankruptcy or for the reorganization of the Company or any other
         obligor on the Notes under Title 11 of the United States Code, or
         any other applicable law, or in case a receiver, assignee or
         trustee in bankruptcy or reorganization, liquidator, sequestrator
         or similar official shall have been appointed for or taken
         possession of the Company or such other obligor, the property of
         the Company or such other obligor, or in the case of any other
         judicial proceedings relative to the Company or such other obligor
         upon the Notes, or to the creditors or property of the Company or
         such other obligor, the Trustee, irrespective of whether the
         principal of the Notes shall then be due and payable as therein
         expressed or by declaration or otherwise and irrespective of
         whether the Trustee shall have made any demand pursuant to the
         provisions of this Section 7.2, shall be entitled and empowered,
         by intervention in such proceedings or otherwise, to file and
         prove a claim or claims for the whole amount of principal,
         premium, if any, and interest owing and unpaid in respect of the
         Notes, and, in case of any judicial proceedings, to file such
         proofs of claim and other papers or documents as may be necessary
         or advisable in order to have the claims of the Trustee and of the
         Noteholders allowed in such judicial proceedings relative to the
         Company or any other obligor on the Notes, its or their creditors,
         or its or their property, and to collect and receive any monies or
         other property payable or deliverable on any such claims, and to
         distribute the same after the deduction of any amounts due the
         Trustee under Section 8.6; and any receiver, assignee or trustee
         in bankruptcy or reorganization, liquidator, custodian or similar
         official is hereby authorized by each of the Noteholders 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
         Noteholders, to pay to the Trustee any amount due it for
         reasonable compensation, expenses, advances and disbursements,
         including counsel fees incurred by it up to the date of such
         distribution.  To the extent that such payment of reasonable
         compensation, expenses, advances and disbursements out of the
         estate in any such proceedings shall be denied for any reason,
         payment of the same shall be secured by a lien on, and shall be
         paid out of, any and all distributions, dividends, monies,
         securities and other property which the holders of the Notes may
         be entitled to receive in such proceedings, whether in liquidation
         or under any plan of reorganization or arrangement or otherwise.

              All rights of action and of asserting claims under this
         Indenture, or under any of the Notes, may be enforced by the
         Trustee without the possession of any of the Notes, or the


                                        -36-





         production thereof on any trial or other proceeding relative
         thereto, and any such suit or proceeding instituted by the Trustee
         shall be brought in its own name and as trustee of an express
         trust, and any recovery of judgment shall, after provision for the
         payment of the reasonable compensation, expenses, disbursements
         and advances of the Trustee, its agents and counsel, be for the
         ratable benefit of the holders of the Notes.  

              In any proceedings brought by the Trustee (and in any
         proceedings involving the interpretation of any provision of this
         Indenture to which the Trustee shall be a party) the Trustee shall
         be held to represent all the holders of the Notes, and it shall
         not be necessary to make any holders of the Notes parties to any
         such proceedings.

              Section 7.3 APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any
         monies collected by the Trustee pursuant to this Article VII shall
         be applied in the order following, at the date or dates fixed by
         the Trustee for the distribution of such monies, upon presentation
         of the several Notes, and stamping thereon the payment, if only
         partially paid, and upon surrender thereof, if fully paid:

                   First:  To the payment of all amounts due the Trustee
         under Section 8.6;

                   Second:  Subject to the provisions of Article IV, in
         case the principal of the outstanding Notes shall not have become
         due and be unpaid, to the payment of interest on the Notes in
         default in the order of the maturity of the installments of such
         interest, with interest (to the extent that such interest has been
         collected by the Trustee) upon the overdue installments of
         interest at the rate borne by the Notes, such payments to
         be made ratably to the persons entitled thereto;

                   Third:  Subject to the provisions of Article IV, in case
         the principal  of the outstanding Notes shall have become due, by
         declaration or otherwise, and be unpaid, to the payment of the
         whole amount then owing and unpaid upon the Notes for principal
         and premium, if any, and interest, with interest on the overdue
         principal and premium, if any, and (to the extent that such
         interest has been collected by the Trustee) upon overdue
         installments of interest at the rate borne by the Notes; and in
         case such monies shall be insufficient to pay in full the whole
         amounts so due and unpaid upon the Notes, then to the payment of
         such principal and premium, if any, and interest without
         preference or priority of principal and premium, if any, over
         interest, or of interest over principal and premium, if any, or of
         any installment of interest over any other installment of
         interest, or of any Note over any other Note, ratably to the



                                        -37-





         aggregate of such principal and premium, if any, and accrued and
         unpaid interest; and

                   Fourth:  Subject to the provisions of Article IV, to the
         payment of the remainder, if any, to the Company or any other
         person lawfully entitled thereto.

              Section 7.4 PROCEEDINGS BY NOTEHOLDER. No holder of any Note
         shall have any right by virtue of or by availing of any provision
         of this Indenture to institute any suit, action or proceeding in
         equity or at law upon or under or with respect to this Indenture,
         or for the appointment of a receiver, trustee, liquidator,
         custodian or other similar official, or for any other remedy
         hereunder, unless such holder previously shall have given to the
         Trustee written notice of an Event of Default and of the
         continuance thereof, as hereinbefore provided, and unless also the
         holders of not less than 25 percent in aggregate principal amount
         of the Notes then outstanding shall have made written request upon
         the Trustee to institute such action, suit or proceeding in its
         own name as Trustee hereunder and shall have offered to the
         Trustee such reasonable indemnity as it may require against the
         costs, expenses and liabilities to be incurred therein or thereby,
         and the Trustee for sixty (60) days after its receipt of such
         notice, request and offer of indemnity, shall have neglected or
         refused to institute any such action, suit or proceeding and no
         direction inconsistent with such written request shall have been
         given to the Trustee pursuant to Section 7.7; it being understood
         and intended, and being expressly covenanted by the taker and
         holder of every Note with every other taker and holder and the
         Trustee, that no one or more holders of Notes shall have any right
         in any manner whatever by virtue of or by availing of any
         provision of this Indenture to affect, disturb or prejudice the
         rights of any other holder of Notes, or to obtain or seek to
         obtain priority over or preference to any other such holder, or to
         enforce any right under this Indenture, except in the manner
         herein provided and for the equal, ratable and common benefit of
         all holders of Notes (except as otherwise provided herein).  For
         the protection and enforcement of this Section 7.4, each and every
         Noteholder and the Trustee shall be entitled to such relief as can
         be given either at law or in equity.

              Notwithstanding any other provision of this Indenture and any
         provision of any Note, the right of any holder of any Note to
         receive payment of the principal of and premium, if any, and
         interest on such Note, on or after the respective due dates
         expressed in such Note, or to institute suit for the enforcement
         of any such payment on or after such respective dates against the
         Company shall not be impaired or affected without the consent of
         such holder.



                                        -38-





              Anything in this Indenture or the Notes to the contrary
         notwithstanding, the holder of any Note, without the consent of
         either the Trustee or the holder of any other Note, in his own
         behalf and for his own benefit, may enforce, and may institute and
         maintain any proceeding suitable to enforce, his rights of
         conversion as provided herein.

              Section 7.5 PROCEEDINGS BY TRUSTEE. In case of an Event of
         Default 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 shall deem most
         effectual to protect and enforce any of such rights, either by
         suit in equity or by action at law or by proceeding in bankruptcy
         or otherwise, whether for the specific enforcement 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.

              Section 7.6 REMEDIES CUMULATIVE AND CONTINUING. Except as
         provided in the last paragraph  of Section 2.6, all powers and
         remedies given by this Article VII to the Trustee or to the
         Noteholders shall, to the extent permitted by law, be deemed
         cumulative and not exclusive of any thereof or of any other powers
         and remedies available to the Trustee or the holders of the Notes,
         by judicial proceedings or otherwise, to enforce the performance
         or observance of the covenants and agreements contained in this
         Indenture, and no delay or omission of the Trustee or of any
         holder of any of the Notes to exercise any right or power accruing
         upon any default or Event of Default occurring and continuing as
         aforesaid shall impair any such right or power, or shall be
         construed to be a waiver of any such default or any acquiescence
         therein; and, subject to the provisions of Section 7.4, every
         power and remedy given by this Article VII or by law to the
         Trustee or to the Noteholders may be exercised from time to time,
         and as often as shall be deemed expedient, by the Trustee or by
         the Noteholders.  

              Section 7.7 DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS
         BY MAJORITY OF NOTEHOLDERS.  The holders of a majority in
         aggregate principal amount of the Notes at the time outstanding
         determined in accordance with Section 9.4 shall have the right to
         direct the time, method, and place of conducting any proceeding
         for any remedy available to the Trustee or exercising any trust or
         power conferred on the Trustee; provided, however, that (a) such
         direction shall not be in conflict with any rule of law or with
         this Indenture, and (b) the Trustee may take any other action
         deemed proper by the Trustee which is not inconsistent with such
         direction.  The holders of a majority in aggregate principal
         amount of the Notes at the time outstanding determined in


                                        -39-





         accordance with Section 9.4 may on behalf of the holders of all of
         the Notes waive any past default or Event of Default hereunder and
         its consequences except (i) a default in the payment of interest
         or premium, if any, on, or the principal of, the Notes, (ii) a
         failure by the Company to convert any Notes into Common Stock,
         (iii) a default in the payment of redemption price pursuant to
         Article III or repurchase price pursuant to Article XVI or (iv) a
         default in respect of a covenant or provisions hereof which under
         Article XI cannot be modified or amended without the consent of
         the holders of all Notes then outstanding. Upon any such waiver
         the Company, the Trustee and the holders of the Notes shall be
         restored to their former positions and rights hereunder; but no
         such waiver shall extend to any subsequent or other default or
         Event of Default or impair any right consequent thereon.  Whenever
         any default or Event of Default hereunder shall have been waived
         as permitted by this Section 7.7, said default or Event of Default
         shall for all purposes of the Notes and this Indenture be deemed
         to have been cured and to be not continuing; but no such waiver
         shall extend to any subsequent or other default or Event of
         Default or impair any right consequent thereon.  

              Section 7.8 NOTICE OF DEFAULTS. The Trustee shall, within
         ninety (90) days after it has knowledge of the occurrence of a
         default, mail to all Noteholders, as the names and addresses of
         such holders appear upon the Note register, notice of all defaults
         known to a Responsible Officer, unless such defaults shall have
         been cured or waived before the giving of such notice; and
         provided that, except in the case of default in the payment of the
         principal of, or premium, if any, or interest on any of the Notes,
         the Trustee shall be protected in withholding such notice if and
         so long as a trust committee of directors and/or Responsible
         Officers of the Trustee in good faith determines that the
         withholding of such notice is in the interests of the Noteholders.

              Section 7.9 UNDERTAKING TO PAY COSTS.  All parties to this
         Indenture agree, and each holder of any Note by his acceptance
         thereof shall be deemed to have agreed, that 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 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 that 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 that the provisions of this Section 7.9 (to the
         extent permitted by law) shall not apply to any suit instituted by
         the Trustee, to any suit instituted by any Noteholder, or group of
         Noteholders, holding in the aggregate more than ten percent in
         principal amount of the Notes at the time outstanding determined


                                        -40-





         in accordance with Section 9.4, or to any suit instituted by any
         Noteholder for the enforcement of the payment of the principal of
         or premium, if any, or interest on any Note on or after the due
         date expressed in such Note or to any suit for the enforcement of
         the right to convert any Note in accordance with the provisions of
         Article XV or to require the Company to repurchase any Note in
         accordance with Article XVI.


                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

              Section 8.1 DUTIES AND RESPONSIBILITIES OF TRUSTEE. The
         Trustee, prior to the occurrence of an Event of Default and after
         the curing 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.  In case an Event of
         Default has occurred (which has not been cured or waived) the
         Trustee shall exercise 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.

              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

                   (a) prior to the occurrence of an Event of Default and
         after the curing or waiving of all Events of Default which may
         have occurred:

                        (1) the duties and obligations of the Trustee shall
         be  determined solely by the express provisions of this Indenture
         and the Trust Indenture Act, and the Trustee shall not be liable
         except for the performance of such duties and obligations as are
         specifically set forth in this Indenture and no implied covenants
         or obligations shall be read into this Indenture and the Trust
         Indenture Act against the Trustee; and

                        (2) in the absence of bad faith and willful
         misconduct 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 therein, upon any
         certificates or opinions furnished to the Trustee and conforming
         to the requirements of this Indenture; but, in the case of any
         such certificates or opinions which by any provisions hereof are
         specifically required to be furnished to the Trustee, the Trustee



                                        -41-





         shall be under a duty to examine the same to determine whether or
         not they conform to the requirements of this Indenture;

                   (b) the Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer or Officers
         of the Trustee, unless the Trustee was negligent in ascertaining
         the pertinent facts;

                   (c) the Trustee shall not be liable with respect to any
         action taken 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 principal amount of the Notes at the time outstanding
         determined as provided in Section 9.4 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; and

                   (d) whether or not therein provided, every provision of
         this Indenture relating to the conduct or affecting the liability
         of, or affording protection to, the Trustee shall be subject to
         the provisions of this Section.

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

              Section 8.2 RELIANCE ON DOCUMENTS, OPINIONS, ETC. Except as
         otherwise provided in Section 8.1:

                   (a) the Trustee may rely and shall be protected in
         acting upon  any resolution, certificate, statement, instrument,
         opinion, report, notice, request, consent, order, bond, debenture,
         note, coupon or other paper or document believed by it in good
         faith to be genuine and to have been signed or presented by the
         proper party or parties;

                   (b) any request, direction, order or demand of the
         Company mentioned herein shall be sufficiently evidenced by an
         Officers' Certificate (unless other evidence in respect thereof be
         herein specifically prescribed); and any resolution of the Board
         of Directors may be evidenced to the Trustee by a copy thereof
         certified by the Secretary or an Assistant Secretary of the
         Company;

                   (c) the Trustee may consult with counsel and any advice
         or Opinion of Counsel shall be full and complete authorization and


                                        -42-





         protection in respect of any action taken or omitted by it
         hereunder in good faith and in accordance with such advice or
         Opinion of Counsel;

                   (d) the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Indenture at the
         request, order or direction of any of the Noteholders pursuant to
         the provisions of this Indenture, unless such Noteholders shall
         have offered to the Trustee reasonable security or indemnity
         against the costs, expenses and liabilities which may be incurred
         therein or thereby;

                   (e) the Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice,
         request, direction, consent, order, bond, debenture or other paper
         or document, but the Trustee, in its discretion, may make such
         further inquiry or investigation into such facts or matters as it
         may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine
         the books, records and premises of the Company, personally or by
         agent or attorney; provided, however, that if the payment within a
         reasonable time to the 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, 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 expenses or liability as a condition to so
         proceeding; the reasonable expenses of every such examination
         shall be paid by the Company or, if paid by the Trustee or any
         predecessor Trustee, shall be repaid by the Company upon demand;
         and 

                   (f) 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 by it with due care hereunder.

              Section 8.3 NO RESPONSIBILITY FOR RECITALS, ETC. The recitals
         contained herein and in the Notes (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 Notes.
         The Trustee shall not be accountable for the use or application by
         the Company of any Notes or the proceeds of any Notes
         authenticated and delivered by the Trustee in conformity with the
         provisions of this Indenture.



                                        -43-





              Section 8.4 TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR
         REGISTRAR MAY OWN NOTES. The Trustee, any paying agent, any
         authenticating agent, any conversion agent or Note registrar, in
         its individual or any other capacity, may become the owner or
         pledgee of Notes with the same rights it would have if it were not
         Trustee, paying agent, conversion agent or Note registrar.

              Section 8.5 MONIES TO BE HELD IN TRUST.  Subject to the
         provisions of Section 13.4, all monies received by the Trustee
         shall, until used or applied as herein provided, be held in trust
         for the purposes for which they were received.  Money held by the
         Trustee in trust hereunder need not be segregated from other funds
         except to the extent required by law.  The Trustee shall be under
         no liability for interest on any money received by it hereunder
         except as may be agreed from time to time by the Company and the
         Trustee.

              Section 8.6 COMPENSATION AND EXPENSES OF TRUSTEE.  The
         Company covenants and agrees to pay to the Trustee from time to
         time, and the Trustee shall be entitled to, reasonable
         compensation for all services rendered by it hereunder in any
         capacity (which shall not be limited by any provision of law in
         regard to the compensation of a trustee of an express trust), and
         the Company will pay or reimburse the Trustee upon its request for
         all reasonable expenses, disbursements and advances reasonably
         incurred or made by the Trustee in accordance with any of the
         provisions of this Indenture (including the reasonable
         compensation and the expenses and disbursements of its counsel and
         of all persons not regularly in its employ) except any such
         expense, disbursement or advance as may arise from its negligence,
         willful misconduct, recklessness or bad faith.  The Company also
         covenants to indemnify the Trustee in any capacity under this
         Indenture and its agents and any authenticating agent for, and to
         hold them harmless against, any loss, liability or expense
         incurred without negligence, willful misconduct, recklessness, or
         bad faith on the part of the Trustee or such agent or
         authenticating agent, as the case may be, and arising out of or in
         connection with the acceptance or administration of this trust or
         in any other capacity hereunder, including the reasonable costs
         and expenses of defending themselves against any claim of
         liability in the premises, provided that (i) each of the Trustee
         or such agent or authenticating agent, as the case may be, shall
         notify the Company promptly of any claim or liability asserted
         against such party for which it may seek indemnification, (ii) the
         Company shall defend such claim and each of the Trustee, such
         agent or authenticating agent, as the case may be, shall cooperate
         with the Company's defense of such claim or liability, (iii) the
         Trustee, such agent and authenticating agent may hire separate
         counsel and the Company shall pay the reasonable fees and expenses
         of such counsel, but (A) the Company will not be required to pay


                                        -44-





         such fees and expenses if it assumes such parties' defense and
         there is no conflict of interest between the Company and such
         parties in connection with such defense and (B) the Company shall
         not be liable, in connection with any such claim or liability or
         substantially similar or related claims or liabilities, at any
         time, for the fees and expenses of more than one separate firm of
         attorneys (in addition to local counsel).  The Company need not
         pay for any settlement made without its written consent.  The
         obligations of the Company under this Section 8.6 to compensate or
         indemnify the Trustee and to pay or reimburse the Trustee for
         expenses, disbursements and advances shall be secured by a lien
         prior to that of the Notes 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 Notes.  The obligation of
         the Company under this Section shall survive the satisfaction and
         discharge of this Indenture.

               When the Trustee and its agents and any authenticating agent
         incur expenses or render services after an Event of Default
         specified in Section 7.1(e) or (f) occurs, the expenses and the
         compensation for the services are intended to constitute expenses
         of administration under any bankruptcy, insolvency or similar
         laws.

              Section 8.7 OFFICERS' CERTIFICATE AS EVIDENCE.  Except as
         otherwise provided in Section 8.1, whenever in the administration
         of the provisions of this Indenture the Trustee shall deem it
         necessary or desirable that a matter be proved or established
         prior to taking or omitting any action hereunder, such matter
         (unless other evidence in respect thereof be herein specifically
         prescribed) may, in the absence of negligence, willful misconduct,
         recklessness, or bad faith on the part of the Trustee, be deemed
         to be conclusively proved and established by an Officers'
         Certificate delivered to the Trustee.

              Section 8.8 CONFLICTING INTERESTS OF TRUSTEE.  If the Trustee
         has or shall acquire a conflicting interest within the meaning of
         the Trust Indenture Act, the Trustee shall either eliminate such
         interest or resign, to the extent and in the manner provided by,
         and subject to the provisions of, the Trust Indenture Act and this
         Indenture.

              Section 8.9 ELIGIBILITY OF TRUSTEE. There shall at all times
         be a Trustee hereunder which shall be a Person that is eligible
         pursuant to the Trust Indenture Act to act as such and has,
         together with its parent, a combined capital and surplus of at
         least $50,000,000.  If such person publishes reports of condition
         at least annually, pursuant to law or to the requirements of any
         supervising or examining authority, then for the purposes of this
         Section, the combined capital and surplus of such person shall be


                                        -45-





         deemed to be its combined capital and surplus as set forth in its
         most recent report of condition so published.  If at any time the
         Trustee shall cease to be eligible in accordance with the
         provisions of this Section, it shall resign immediately in the
         manner and with the effect hereinafter specified in this Article.

              Section 8.10 RESIGNATION OR REMOVAL OF TRUSTEE.

                   (a) The Trustee may at any time resign by giving written
         notice of such resignation to the Company and to the holders of
         Notes.  Upon receiving such notice of resignation, the Company
         shall promptly appoint a successor trustee by written instrument,
         in duplicate, executed by order of the Board of Directors, one
         copy 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
         sixty (60) days after the mailing of such notice of resignation to
         the Noteholders, the resigning Trustee may petition any court of
         competent jurisdiction for the appointment of a successor trustee,
         or any Noteholder who has been a bona fide holder of a Note or
         Notes for at least six months may, subject to the provisions of
         Section 7.9, 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 Section
         8.8 after   written request therefor by the Company or by any
         Noteholder who has been a bona fide holder of a Note or Notes for
         at least six months; or

                        (2)  the Trustee shall cease to be eligible in
         accordance with the provisions of Section 8.9 and shall fail to
         resign after written request therefor by the Company or by any
         such Noteholder; 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 for the purpose of rehabilitation,
         conservation or liquidation; then, in any such case, the Company
         may remove the Trustee and appoint a successor trustee by written
         instrument, in duplicate, executed by order of the Board of
         Directors, one copy of which instrument shall be delivered to
         the Trustee so removed and one copy to the successor trustee, or,


                                        -46-





         subject to the provisions of Section 7.9, any Noteholder who has
         been a bona fide holder of a Note or Notes 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 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 successor
         trustee.
                   (c)  The holders of a majority in aggregate principal
         amount of the Notes at the time outstanding may at any time remove
         the Trustee and nominate a successor trustee which shall be deemed
         appointed as successor trustee unless within ten (10) days after
         notice to the Company of such nomination the Company objects
         thereto, in which case the Trustee so removed or any Noteholder,
         upon the terms and conditions and otherwise as in Section 8.10(a)
         provided, may petition any court of competent jurisdiction for an
         appointment of a successor trustee.

                   (d)  Any resignation or removal of the Trustee and
         appointment of a successor trustee pursuant to any of the
         provisions of this Section 8.10 shall become effective upon
         acceptance of appointment by the successor trustee as provided in
         Section 8.11. 

              Section 8.11  ACCEPTANCE BY SUCCESSOR TRUSTEE.  Any successor
         trustee appointed as provided in Section 8.10 shall execute,
         acknowledge and deliver to the Company and to its predecessor
         trustee an instrument accepting such appointment hereunder, and
         thereupon the resignation or removal of the predecessor trustee
         shall become effective and such successor trustee, without any
         further act, deed or conveyance, shall become vested with all the
         rights, powers, duties and obligations of its predecessor
         hereunder, with like effect as if originally named as trustee
         herein; but, nevertheless, on the written request of the Company
         or of the successor trustee, the trustee ceasing to act shall,
         upon payment of any amounts then due it pursuant to the provisions
         of Section 8.6, execute and deliver an instrument transferring to
         such successor trustee all the rights and powers of the trustee so
         ceasing to act.  Upon reasonable request of any such successor
         trustee, the Company shall execute such instruments in writing as
         necessary for fully and certainly vesting in and confirming to
         such successor trustee all such rights and powers.  Any trustee
         ceasing to act shall, nevertheless, retain a lien upon all
         property and funds held or collected by such trustee as such,
         except for funds held in trust for the benefit of holders of
         particular Notes, to secure any amounts then due it pursuant to
         the provisions of Section 8.6.

              No successor trustee shall accept appointment as provided in
         this Section 8.11 unless at the time of such acceptance such


                                        -47-





         successor trustee shall be qualified under the provisions of
         Section 8.8 and be eligible under the provisions of Section 8.9.

              Upon acceptance of appointment by a successor trustee as
         provided in this Section 8.11, either the Company or the former
         trustee shall mail or cause to be mailed notice of the succession
         of such trustee hereunder to the holders of Notes at their
         addresses as they shall appear on the Note register.  If the
         Company or the former trustee fails to mail such notice within ten
         (10) days after acceptance of appointment by the successor
         trustee, the successor trustee shall mail or cause such notice to
         be mailed to the holders of Notes.

              Section 8.12  SUCCESSION BY MERGER, ETC.  Any corporation
         into which the Trustee may be merged or converted or with which it
         may be consolidated, or any corporation resulting from any merger,
         conversion or consolidation to which the Trustee shall be a party,
         or any corporation succeeding to all or substantially all of the
         corporate trust business of the Trustee (including any trust
         created by this Indenture), shall be the successor to the Trustee
         hereunder without the execution or filing of any paper or any
         further act on the part of any of the parties hereto, provided
         that in the case of any corporation succeeding to all or
         substantially all of the corporate trust business of the Trustee
         such corporation shall be qualified under the provisions of
         Section 8.8 and eligible under the provisions of Section 8.9. In
         case at the time such successor to the Trustee shall succeed to
         the trusts created by this Indenture, any of the Notes shall have
         been authenticated but not delivered, any such successor to the
         Trustee may adopt the certificate of authentication of any
         predecessor trustee or authenticating agent appointed by such
         predecessor trustee, and deliver such Notes so authenticated; and
         in case at that time any of the Notes shall not have been
         authenticated, any successor to the Trustee or an authenticating
         agent appointed by such successor trustee may authenticate such
         Notes either in the name of any predecessor trustee 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
         Notes or in this Indenture provided that the certificate of the
         Trustee shall have; provided, however, that the right to adopt the
         certificate of authentication of any predecessor Trustee or
         authenticate Notes in the name of any predecessor Trustee shall
         apply only to its successor or successors by merger, conversion or
         consolidation.

              Section 8.13  LIMITATION ON RIGHTS OF TRUSTEE AS CREDITOR.
         If and when the Trustee shall be or become a creditor of the
         Company (or any other obligor upon the Notes), the Trustee shall
         be subject to the provisions of the Trust Indenture Act regarding



                                        -48-





         the collection of the claims against the Company (or any such
         other obligor).


                                  ARTICLE IX

                        CONCERNING THE NOTEHOLDERS


              Section 9.1  ACTION BY NOTEHOLDERS.  Whenever in this
         Indenture it is provided that the holders of a specified
         percentage in aggregate principal amount of the Notes may take any
         action (including the making of any demand or request, the giving
         of any notice, consent or waiver or the taking of any other
         action), the fact that at the time of taking any such action, the
         holders of such specified percentage have joined therein may be
         evidenced (a) by any instrument or any number of instruments of
         similar tenor executed by Noteholders in person or by agent or
         proxy appointed in writing, or (b) by the record of the holders of
         Notes voting in favor thereof at any meeting of Noteholders duly
         called and held in accordance with the provisions of Article X, or
         (c) by a combination of such instrument or instruments and any
         such record of such a meeting of Noteholders. Whenever the Company
         or the Trustee solicits the taking of any action by the holders of
         the Notes by a written instrument or at a meeting, the Company or
         the Trustee shall fix in advance of such solicitation, a date as
         the record date for determining holders entitled to execute such
         instrument or vote at such meeting. The record date shall be not
         more than fifteen (15) days prior to the date of commencement of
         solicitation of such action by written instrument and not more
         than sixty (60) days prior to the date of such meeting, as the
         case may be. With respect to any record date set pursuant to this
         Section 9.1 relating to an action by written instrument, the party
         hereto which sets such record date may designate any day as the
         "Expiration Date" and from time to time may change the Expiration
         Date to any earlier or later day; provided that no such change
         shall be effective unless notice of the proposed new Expiration
         Date is given to the other party hereto in writing, and to each
         holder of Notes in the manner set forth in 17.3, on or prior to
         the existing Expiration Date.  If an Expiration Date is not
         designated with respect to any record date set pursuant to this
         Section 9.1, the party hereto which set such record date shall be
         deemed to have initially designated the 180th day after such
         record date as the Expiration Date with respect thereto, subject
         to its right to change the Expiration Date as provided in this
         paragraph. Notwithstanding the foregoing, no Expiration Date shall
         be later than the 180th day after the applicable record date.

              Section 9.2  PROOF OF EXECUTION BY NOTEHOLDERS.  Subject to
         the provisions of Sections 8.1, 8.2 and 10.5, proof of the


                                        -49-





         execution of any instrument by a Noteholder or his agent or proxy
         shall be sufficient if made in accordance with such reasonable
         rules and regulations as may be prescribed by the Trustee or in
         such manner as shall be satisfactory to the Trustee.  The holding
         of Notes shall be proved by the Note register or by a certificate
         of the Note registrar.

              The record of any Noteholders' meeting shall be proved in the
         manner provided in Section 10.6.

              Section 9.3  WHO ARE DEEMED ABSOLUTE OWNERS.  The Company,
         the Trustee, any authenticating agent, any paying agent, any
         conversion agent and any Note registrar may deem the person in
         whose name such Note shall be registered upon the Note register to
         be, and may treat him as, the absolute owner of such Note (whether
         or not such Note shall be overdue and notwithstanding any notation
         of ownership or other writing thereon) for the purpose of
         receiving payment of or on account of the principal of, premium,
         if any, and interest on such Note, for conversion of such Note and
         for all other purposes; and neither the Company nor the Trustee
         nor any paying agent nor any conversion agent nor any
         authenticating agent nor any Note registrar shall be affected by
         any notice to the contrary.  All such payments so made to any
         holder for the time being, or upon his order, shall be valid, and,
         to the extent of the sum or sums so paid, effectual to fully
         satisfy and discharge the liability for monies payable upon any
         such Note.

              Section 9.4  COMPANY-OWNED NOTES DISREGARDED.  In determining
         whether the holders of the requisite aggregate principal amount of
         Notes have concurred in any direction, consent, waiver or other
         action under this Indenture, Notes which are owned by the Company
         or any other obligor on the Notes or by any person directly or
         indirectly controlling or controlled by or under direct or
         indirect common control with the Company or any other obligor on
         the Notes shall be disregarded and deemed not to be outstanding
         for the purpose of any such determination; provided that for the
         purposes of determining whether the Trustee shall be protected in
         relying on any such direction, consent, waiver or other action
         only Notes which a Responsible Officer knows are so owned shall be
         so disregarded. Notes so owned which have been pledged in good
         faith may be regarded as outstanding for the purposes of this
         Section 9.4 if the pledgee shall establish to the satisfaction of
         the Trustee the pledgee's right to vote such Notes and that the
         pledgee is not the Company, any other obligor on the Notes or a
         person directly or indirectly controlling or controlled by or
         under direct or indirect common control with the Company or any
         such other obligor.  In the case of a dispute as to such right,
         any decision by the Trustee taken upon the advice of counsel shall
         be full protection to the Trustee.  Upon request of the Trustee,


                                        -50-





         the Company shall furnish to the Trustee promptly an Officers'
         Certificate listing and identifying all Notes, if any, known by
         the Company to be owned or held by or for the account of any of
         the above described persons; and, subject to Section 8.1, the
         Trustee shall be entitled to accept such Officers' Certificate as
         conclusive evidence of the facts therein set forth and of the fact
         that all Notes not listed therein are outstanding for the purpose
         of any such determination.

              Section 9.5  REVOCATION OF CONSENTS: FUTURE HOLDERS BOUND.
         At any time prior to (but not after) the evidencing to the
         Trustee, as provided in Section 9.1, of the taking of any action
         by the holders of the percentage in aggregate principal amount of
         the Notes specified in this Indenture in connection with such
         action, any holder of a Note which is shown by the evidence to be
         included in the Notes the holders of which have consented to such
         action may, by filing written notice with the Trustee at its
         Corporate Trust Office and upon proof of holding as provided in
         Section 9.2, revoke such action so far as it concerns such Note.
         Except as aforesaid, any such action taken by the holder of any
         Note shall be conclusive and binding upon such holder and upon all
         future holders and owners of such Note and of any Notes issued in
         exchange or substitution therefor, irrespective of whether any
         notation in regard thereto is made upon such Note or any Note
         issued in exchange or substitution therefor.


                                  ARTICLE X

                             NOTEHOLDERS' MEETINGS


              Section 10.1  PURPOSE OF MEETINGS.  A meeting of Noteholders

         provisions of this Article X for any of the following purposes:

                        (1)  to give any notice to the Company or to the
         Trustee or to give any directions to the Trustee permitted under
         this Indenture, or to consent to the waiving of any default or
         Event of Default hereunder and its consequences, or to take any
         other action authorized to be taken by Noteholders pursuant to any
         of the provisions of Article VII;

                        (2)  to remove the Trustee and nominate a successor
         trustee pursuant to the provisions of Article VIII;

                        (3)  to consent to the execution of an indenture or 
         indentures supplemental hereto pursuant to the provisions of
         Section 11.2; or



                                        -51-




                        (4)  to take any other action authorized to be
         taken by or on behalf of the holders of any specified aggregate
         principal amount of the Notes under any other provision of this
         Indenture or under applicable law.

              Section 10.2  CALL OF MEETINGS BY TRUSTEE.  The Trustee may
         at any time call a meeting of Noteholders to take any action
         specified in Section 10.1, to be held at such time and at such
         place at a location within 10 miles of the Corporate Trust Office
         or the Borough of Manhattan, The City of New York, as the Trustee
         shall determine.  Notice of every meeting of the Noteholders,
         setting forth the time and the place of such meeting and in
         general terms the action proposed to be taken at such meeting and
         the establishment of any record date pursuant to Section 9.1,
         shall be mailed to holders of Notes at their addresses as they
         shall appear on the Note register.  Such notice shall also be
         mailed to the Company.  Such notices shall be mailed not less than
         twenty (20) nor more than ninety (90) days prior to the date fixed
         for the meeting.

              Any meeting of Noteholders shall be valid without notice if
         the holders of all Notes then outstanding are present in person or
         by proxy or if notice is waived before or after the meeting by the
         holders of all Notes outstanding, and if the Company and the
         Trustee are either present by duly authorized representatives or
         have, before or after the meeting, waived notice.

              Section 10.3  CALL OF MEETINGS BY COMPANY OR NOTEHOLDERS.  In
         case at any time the Company, pursuant to a resolution of its
         Board of Directors, or the holders of at least ten percent in

         have requested the Trustee to call a meeting of Noteholders, by
         written request setting forth in reasonable detail the action
         proposed to be taken at the meeting, and the Trustee shall not
         have mailed the notice of such meeting within twenty (20) days
         after receipt of such request, then the Company or such
         Noteholders may determine the time and the place at any location
         within 10 miles of the corporate Trust Office or the Borough of
         Manhattan, The City of New York for such meeting and may call such
         meeting to take any action authorized in Section 10.1, by mailing
         notice thereof as provided in Section 10.2.

              Section 10.4  QUALIFICATIONS FOR VOTING.  To be entitled to
         vote at any meeting of Noteholders a person shall (a) be a holder
         of one or more Notes on the record date pertaining to such meeting
         or (b) be a person appointed by an instrument in writing as proxy
         by a holder of one or more Notes.  The only persons who shall be
         entitled to be present or to speak at any meeting of Noteholders
         shall be the persons entitled to vote at such meeting and their



                                        -52-





         counsel and any representatives of the Trustee and its counsel and
         any representatives of the Company and its counsel.

              Section 10.5  REGULATIONS.  Notwithstanding any other
         provisions of this Indenture, the Trustee may make such reasonable
         regulations as it may deem advisable for any meeting of
         Noteholders, in regard to proof of the holding of Notes and of the
         appointment of proxies, and in regard to the appointment and
         duties of inspectors of votes, the submission and examination of
         proxies, certificates and other evidence of the right to vote, and
         such other matters concerning the conduct of the meeting as it
         shall think fit.

              The Trustee shall, by an instrument in writing, appoint a
         temporary chairman of the meeting, unless the meeting shall have
         been called by the Company or by Noteholders as provided in
         Section 10.3, in which case the Company or the Noteholders calling
         the meeting, as the case may be, shall in like manner appoint a
         temporary chairman.  A permanent chairman and a permanent
         secretary of the meeting shall be elected by vote of the holders
         of a majority in principal amount of the Notes represented at the
         meeting and entitled to vote at the meeting.

              Subject to the provisions of Section 9.4, at any meeting each
         Noteholder or proxyholder shall be entitled to one vote for each
         $1,000 principal amount of Notes held or represented by him;
         provided, however, that no vote shall be cast or counted at any
         meeting in respect of any Note challenged as not outstanding and
         ruled by the chairman of the meeting to be not outstanding.  The
         chairman of the meeting shall have no right to vote other than by
         virtue of Notes held by him or instruments in writing as aforesaid
         duly designating him as the proxy to vote on behalf of other
         Noteholders.  Any meeting of Noteholders duly called pursuant to
         the provisions of Section 10.2 or 10.3 may be adjourned from time
         to time by the holders of a majority of the aggregate principal
         amount of Notes represented at the meeting, whether or not
         constituting a quorum, and the meeting may be held as so adjourned
         without further notice.

              Section 10.6  VOTING. The vote upon any resolution submitted
         to any meeting of Noteholders shall be by written ballot on which
         shall be subscribed the signatures of the holders of Notes or of
         their representatives by proxy and the principal amount of the
         Notes held or represented by them.  The permanent chairman of the
         meeting shall appoint two inspectors of votes who shall count all
         votes cast at the meeting for or against any resolution and who
         shall make and file with the secretary of the meeting their
         verified written reports in duplicate of all votes cast at the
         meeting. A record in duplicate of the proceedings of each meeting
         of Noteholders shall be prepared by the secretary of the meeting


                                        -53-





         and there shall be attached to said record the original reports of
         the inspectors of votes on any vote by ballot taken thereat and
         affidavits by one or more persons having knowledge of the facts
         setting forth a copy of the notice of the meeting and showing that
         said notice was mailed as provided in Section 10.2. The record
         shall show the principal amount of the Notes voting in favor of or
         against any resolution.  The record shall be signed and verified
         by the affidavits of the permanent chairman and secretary of the
         meeting and one of the duplicates shall be delivered to the
         Company and the other to the Trustee to be preserved by the
         Trustee, the latter to have attached thereto the ballots voted at
         the meeting.

              Any record so signed and verified shall be conclusive
         evidence of the matters therein stated.

              Section 10.7  NO DELAY OF RIGHTS BY MEETING.  Nothing in this
         Article X contained shall be deemed or construed to authorize or
         permit, by reason of any call of a meeting of Noteholders or any
         rights expressly or impliedly conferred hereunder to make such
         call, any hindrance or delay in the exercise of any right or
         rights conferred upon or reserved to the Trustee or to the
         Noteholders under any of the provisions of this Indenture or of
         the Notes.


                                  ARTICLE XI

                             SUPPLEMENTAL INDENTURES


              Section 11.1  SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF
         NOTEHOLDERS.  The Company, when authorized by the resolutions of
         the Board of Directors, and the Trustee may from time to time and

         rights of the holders of Notes pursuant to the requirements of
         Section 15.6;

                   (b)  subject to Article IV, to convey, transfer, assign,
          mortgage or pledge to the Trustee as security for the Notes, any
         property or assets;

                   (c)  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 XII;



                                        -54-





                   (d)  to add to the covenants of the Company such further
         covenants, restrictions or conditions as the Board of Directors
         and the Trustee shall consider to be for the benefit of the
         holders of Notes, and to make the occurrence, or the occurrence
         and continuance, of a default in any such additional covenants,
         restrictions or conditions a default or an Event of Default
         permitting the enforcement of all or any of the several remedies
         provided in this Indenture as herein set forth; provided, however,
         that in respect of any such additional covenant, restriction or
         condition such supplemental indenture may provide for a particular
         period of grace after default (which period may be shorter or
         longer than that allowed in the case of other defaults) or may
         provide for an immediate enforcement upon such default or may
         limit the remedies available to the Trustee upon such default;

                   (e)  to provide for the issuance under this Indenture of
         Notes in coupon form (including Notes registrable as to principal
         only) and to provide for exchangeability of such Notes with the
         Notes issued hereunder in fully registered form and to make all
         appropriate changes for such purpose;

                   (f)  to cure any ambiguity or to correct or supplement
         any provision contained herein or in any supplemental indenture
         which may be defective or inconsistent with any other provision
         contained herein or in any supplemental indenture, or to make such
         other provisions in regard to matters or questions arising under
         this Indenture which shall not materially adversely affect the
         interests of the holders of the Notes;

                   (g)  to evidence and provide for the acceptance of
         appointment hereunder by a successor Trustee with respect to the
         Notes; or
                   (h)  to modify, eliminate or add to the provisions of
         this Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the Trust Indenture Act, or
         under any similar federal statute hereafter enacted.  

              Upon the request of the Company, accompanied by a copy of the
         resolutions of the Board of Directors certified by its Secretary
         or Assistant Secretary authorizing the execution of any such
         supplemental indenture, the Trustee shall join with the Company in
         the execution of any such supplemental indenture, to make any
         further appropriate agreements and stipulations which may be
         therein contained and to accept the conveyance, transfer and
         assignment of any property thereunder, but the Trustee shall not
         be obligated to, but may in its discretion, enter into any
         supplemental indenture which affects the Trustee's own rights,
         duties or immunities under this Indenture or otherwise.




                                        -55-





              Any supplemental indenture authorized by the provisions of
         this Section 11.1 may be executed by the Company and the Trustee
         without the consent of the holders of any of the Notes at the time
         outstanding, notwithstanding any of the provisions of Section
         11.2.

              Section 11.2  SUPPLEMENTAL INDENTURES WITH CONSENT OF
         NOTEHOLDERS.  With the consent (evidenced as provided in Article
         IX) of the holders of not less than a majority in aggregate
         principal amount of the Notes at the time outstanding, the
         Company, when authorized by the resolutions of the 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 provisions to or changing in any manner or
         eliminating any of the provisions of this Indenture or any
         supplemental indenture or of modifying in any manner the rights of
         the holders of the Notes; provided, however, that no such
         supplemental indenture shall (i) extend the fixed maturity of any
         Note, or reduce the rate or extend the time of payment of interest
         thereon, or reduce the principal amount thereof or premium, if
         any, thereon, or reduce any amount payable on redemption thereof,
         or impair the right of any Noteholder to institute suit for the
         payment thereof, or make the principal thereof or interest or
         premium, if any, thereon payable in any coin or currency other
         than that provided in the Notes, or modify the provisions of this
         Indenture with respect to the subordination of the Notes in a
         manner adverse to the Noteholders in any material respect, or
         change the obligation of the Company to repurchase any Note upon
         the happening of a Repurchase Event in a manner adverse to the
         holder of Notes, or impair the right to convert the Notes into
         Common Stock subject to the terms set forth herein, including
         Section 15.6, in each case without the consent of the holder of
         each Note so affected, or (ii) reduce the aforesaid percentage of
         Notes, the holders of which are required to consent to any such
         supplemental indenture, without the consent of the holders of all
         Notes then outstanding.  

              Upon the request of the Company, accompanied by a copy of the
         resolutions of the Board of Directors certified by its Secretary
         or an Assistant Secretary authorizing the execution of any such
         supplemental indenture, and upon the filing with the Trustee of
         evidence of the consent of Noteholders 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 Noteholders
         under this Section 11.2 to approve the particular form of any


                                        -56-





         proposed supplemental indenture, but it shall be sufficient if
         such consent shall approve the substance thereof.

              Section 11.3  EFFECT OF SUPPLEMENTAL INDENTURE.  Any
         supplemental indenture executed pursuant to the provisions of this
         Article XI shall comply with the Trust Indenture Act, as then in
         effect; provided that this Section 11.3 shall not require such
         supplemental indenture or the Trustee to be qualified under the
         Trust Indenture Act prior to the time such qualification is in
         fact required under the terms of the Trust Indenture Act or the
         Indenture has been qualified under the Trust Indenture Act, nor
         shall it constitute any admission or acknowledgment by any party
         to such supplemental indenture that any such qualification is
         required prior to the time such qualification is in fact required
         under the terms of the Trust Indenture Act or the Indenture has
         been qualified under the Trust Indenture Act.  Upon the execution
         of any supplemental indenture pursuant to the provisions of this
         Article XI, this Indenture shall be and be deemed to be modified
         and amended in accordance therewith and the respective rights,
         limitation of rights, obligations, duties and immunities under
         this Indenture of the Trustee, the Company and the holders of
         Notes 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.

              Section 11.4  NOTATION ON NOTES.  Notes authenticated and
         delivered after the execution of any supplemental indenture
         pursuant to the provisions of this Article XI may bear a notation 
         in form approved by the Trustee as to any matter provided for in
         such supplemental indenture.  If the Company or the Trustee shall
         so determine, new Notes so modified as to conform, in the opinion
         of the Trustee and the Board of Directors, to any modification of
         this Indenture contained in any such supplemental indenture may,
         at the Company's expense, be prepared and executed by the Company,
         authenticated by the Trustee (or an authenticating agent duly
         appointed by the Trustee pursuant to Section 17.11) and delivered
         in exchange for the Notes then outstanding, upon surrender of such
         Notes then outstanding.

              Section 11.5  EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL
         INDENTURE TO BE FURNISHED TRUSTEE. The Trustee, subject to the
         provisions of Sections 8.1 and 8.2, may receive an Officers'
         Certificate and an Opinion of Counsel as conclusive evidence that
         any supplemental indenture executed pursuant hereto complies with
         the requirements of this Article XI.

                                     ARTICLE XII

                   CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE 


              Section 12.1  COMPANY MAY CONSOLIDATE ETC. ON CERTAIN TERMS.
         Subject to the provisions of Section 12.2, nothing contained in
         this Indenture or in any of the Notes shall prevent any
         consolidation or merger of the Company with or into any other
         corporation or corporations (whether or not affiliated with the
         Company), or successive consolidations or mergers in which the
         Company or its successor or successors shall be a party or
         parties, or shall prevent any sale, conveyance or lease (or
         successive sales, conveyances or leases) of all or substantially
         all of the property of the Company, to any other corporation
         (whether or not affiliated with the Company), authorized to
         acquire and operate the same and which shall in each case be
         organized under the laws of the United States of America, any
         state thereof or the District of Columbia; provided, that upon any
         such consolidation, merger, sale, conveyance or lease, the due and
         punctual payment of the principal of and premium, if any, and
         interest on all of the Notes, according to their tenor, and the
         due and punctual performance and observance of all of the
         covenants and conditions of this Indenture to be performed by the
         Company, shall be expressly assumed, by supplemental indenture
         satisfactory in form to the Trustee, executed and delivered to the
         Trustee by the corporation (if other than the Company) formed by
         such consolidation, or into which the Company shall have been
         merged, or by the corporation which shall have acquired or leased
         such property, and such supplemental indenture shall provide for
         the applicable conversion rights set forth in Section 15.6.  

              Section 12.2  SUCCESSOR CORPORATION TO BE SUBSTITUTED.  In
         case of any such consolidation, merger, sale, conveyance or lease
         and upon the assumption by the successor corporation, by
         supplemental indenture, executed and delivered to the Trustee and
         satisfactory in form to the Trustee, of the due and punctual
         payment of the principal of and premium, if any, and interest on
         all of the Notes and the due and punctual performance of all of
         the covenants and conditions of this Indenture to be performed by
         the Company, such successor corporation shall succeed to and be
         substituted for the Company, with the same effect as if it had
         been named herein as the party of the first part.  Such successor
         corporation thereupon may cause to be signed, and may issue either
         in its own name or in the name of Iomega Corporation any or all of
         the Notes issuable hereunder which theretofore shall not have been
         signed by the Company and delivered to the Trustee; and, upon the
         order of such successor corporation instead of the Company and
         subject to all the terms, conditions and limitations in this
         Indenture prescribed, the Trustee shall authenticate and shall


                                        -58-





         deliver, or cause to be authenticated and delivered, any Notes
         which previously shall have been signed and delivered by the
         officers of the Company to the Trustee for authentication, and any
         Notes which such successor corporation thereafter shall cause to
         be signed and delivered to the Trustee for that purpose.  All the
         Notes so issued shall in all respects have the same legal rank and
         benefit under this Indenture as the Notes theretofore or
         thereafter issued in accordance with the terms of this Indenture
         as though all of such Notes had been issued at the date of the
         execution hereof.  In the event of any such consolidation, merger,
         sale or conveyance (but not in the event of such lease), the
         person named as the "Company" in the first paragraph of this
         Indenture or any successor which shall thereafter have become such
         in the manner prescribed in this Article XII may be dissolved,
         wound up and liquidated at any time thereafter and such person
         shall be released from its liabilities as obligor and maker of the
         Notes and from its obligations under this Indenture.  

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

              Section 12.3  OPINION OF COUNSEL TO BE GIVEN TRUSTEE.  The
         Trustee, subject to Sections 8.1 and 8.2, shall receive an
         Officers' Certificate and an Opinion of Counsel as conclusive
         evidence that any such consolidation, merger, sale, conveyance or
         lease and any such assumption complies with the provisions of this
         Article XII.


                                  ARTICLE XIII

                        SATISFACTION AND DISCHARGE OF INDENTURE

              Section 13.1  DISCHARGE OF INDENTURE.  When (a) the Company
         shall deliver to the Trustee for cancellation all Notes
         theretofore authenticated (other than any Notes which have been
         destroyed, lost or stolen and in lieu of or in substitution for
         which other Notes shall have been authenticated and delivered) and
         not theretofore canceled, or (b) all the Notes not theretofore
         canceled or delivered to the Trustee for cancellation shall have
         become due and payable, or are by their terms to become due and
         payable within one year or are to be called for redemption within
         one year under arrangements satisfactory to the Trustee for the
         giving of notice of redemption, and the Company shall deposit with
         the Trustee, in trust, funds sufficient to pay at maturity or upon
         redemption of all of the Notes (other than any Notes which shall
         have been mutilated, destroyed, lost or stolen and in lieu of or
         in substitution for which other Notes shall have been


                                        -59-





         authenticated and delivered) not theretofore canceled or delivered
         to the Trustee for cancellation, including principal and 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, then this Indenture shall cease to be of
         further effect (except as to (i) remaining rights of registration
         of transfer, substitution and exchange and conversion of Notes,
         (ii) rights hereunder of Noteholders to receive payments of
         principal of and premium, if any, and interest on, the Notes and
         the other rights, duties and obligations of Noteholders, as
         beneficiaries hereof with respect to the amounts, if any, so
         deposited with the Trustee and (iii) the rights, obligations and
         immunities of the Trustee hereunder), and the Trustee, on demand
         of the Company accompanied by an Officers' Certificate and an
         Opinion of Counsel as required by Section 17.5 and at the cost and
         expense of the Company, shall execute proper instruments
         acknowledging satisfaction of and discharging this Indenture; the
         Company, however, hereby agreeing to reimburse the Trustee for any
         costs or expenses thereafter reasonably and properly incurred by
         the Trustee and to compensate the Trustee for any services
         thereafter reasonably and properly rendered by the Trustee in
         connection with this Indenture or the Notes.

              Section 13.2  DEPOSITED MONIES TO BE HELD IN TRUST BY
         TRUSTEE.  Subject to Section 13.4, all monies deposited with the
         Trustee pursuant to Section 13.1 and not in violation of Article
         IV shall be held in trust for the sole benefit of the Noteholders
         and not to be subject to the subordination provisions of Article
         IV, and such monies shall be applied by the Trustee to the
         payment, either directly or through any paying agent (including
         the Company if acting as its own paying agent), to the holders of
         the particular Notes for the payment or redemption of which such
         monies have been deposited with the Trustee, of all sums due and
         to become due thereon for principal and interest and premium, if
         any.

              Section 13.3  PAYING AGENT TO REPAY MONIES HELD.  Upon the
         satisfaction and discharge of this Indenture, all monies then held
         by any paying agent of the Notes (other than the Trustee) shall,
         upon written request of the Company, be repaid to it or paid to
         the Trustee, and thereupon such paying agent shall be released
         from all further liability with respect to such monies.

              Section 13.4  RETURN OF UNCLAIMED MONIES.  Subject to the
         requirements of applicable law, any monies deposited with or paid
         to the Trustee for payment of the principal of, premium, if any,
         or interest on Notes and not applied but remaining unclaimed by
         the holders of Notes for two years after the date upon which the
         principal of, premium, if any, or interest on such Notes, as the


                                        -60-





         case may be, shall have become due and payable, shall be repaid to
         the Company by the Trustee on demand and all liability of the
         Trustee shall thereupon cease with respect to such monies; and the
         holder of any of the Notes shall thereafter look only to the
         Company for any payment which such holder may be entitled to
         collect unless an applicable abandoned property law designates
         another Person.

              Section 13.5  REINSTATEMENT.  If the Trustee or the paying
         agent is unable to apply any money in accordance with Section 13.2
         by reason of any order or judgment of any court or governmental
         authority enjoining, restraining or otherwise prohibiting such
         application, the Company's obligations under this Indenture and
         the Notes shall be revived and reinstated as though no deposit had
         occurred pursuant to Section 13.1 until such time as the Trustee
         or the paying agent is permitted to apply all such money in
         accordance with Section 13.2; provided, however,  that if the
         Company makes any payment of interest on or principal of any Note
         following the reinstatement of its obligations, the Company shall
         be subrogated to the rights of the holders of such Notes to
         receive such payment from the money held by the Trustee or paying
         agent.


                                  ARTICLE XIV

                        IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                             OFFICERS AND DIRECTORS


              Section 14.1  INDENTURE AND NOTES SOLELY CORPORATE
         OBLIGATIONS.  No recourse for the payment of the principal of or
         premium, if any, or interest on any Note, or for any claim based
         thereon or otherwise in respect thereof, and no recourse under or
         upon any obligation, covenant or agreement of the Company in this
         Indenture or in any supplemental indenture or in any Note, or
         because of the creation of any indebtedness represented thereby,
         shall be had against any incorporator, stockholder, employee,
         agent, officer, or director or subsidiary, as such, past, present
         or future, of the Company or of any successor corporation, either
         directly or through the Company or any successor corporation,
         whether by virtue of any constitution, statute or rule of law, or
         by the enforcement of any assessment or penalty or otherwise; it
         being expressly understood that all such liability is hereby
         expressly waived and released as a condition of, and as a
         consideration for, the execution of this Indenture and the issue
         of the Notes.

                                  ARTICLE XV

                             CONVERSION OF NOTES


               Section 15.1  RIGHT TO CONVERT.  Subject to and upon
         compliance with the provisions of this Indenture, the holder of
         any Note shall have the right, at his option, at any time after
         sixty (60) days following the latest date of original issuance of
         the Notes and prior to the close of business on March 15, 2001
         (except that, with respect to any Note or portion of a Note which
         shall be called for redemption, such right shall terminate, except
         as provided in Section 15.2 or Section 3.4, at the close of
         business on the second Business Day next preceding the date fixed
         for redemption of such Note or portion of a Note unless the
         Company shall default in the payment due upon redemption thereof
         or that, with respect to a Note or portion of a Note submitted for
         repurchase, such right shall terminate at the close of business on
         the second Business Date next preceding the Repurchase Date unless
         the Company shall default in the payment due on repurchase) to
         convert the principal amount of any such Note, or any portion of
         such principal amount which is $1,000 or an integral multiple
         thereof, into that number of fully paid and non-assessable shares
         of Common Stock (as such shares shall then be constituted)
         obtained by dividing the principal amount of the Note or portion
         thereof surrendered for conversion by the Conversion Price in
         effect at such time, by surrender of the Note so to be converted
         in whole or in part in the manner provided, together with any
         required funds, in Section 15.2.  A holder of Notes is not
         entitled to any rights of a holder of Common Stock until such
         holder has converted his Notes to Common Stock, and only to the
         extent such Notes are deemed to have been converted to Common
         Stock under this Article XV.

              Section 15.2  EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF
         COMMON STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR
         DIVIDENDS.  In order to exercise the conversion privilege with
         respect to any Note, the holder of any such Note to be converted
         in whole or in part shall surrender such Note, duly endorsed, at
         an office or agency maintained by the Company pursuant to Section
         5.2, accompanied by the funds, if any, required by the last
         paragraph of this Section 15.2, and shall give written notice of
         conversion in the form provided on the Notes (or such other notice
         which is acceptable to the Company) to the office or agency that
         the holder elects to convert such Note or the portion thereof
         specified in said notice.  Such notice shall also state the name
         or names (with address or addresses) in which the certificate or
         certificates for shares of Common Stock which shall be issuable on
         such conversion shall be issued, and shall be accompanied by
         transfer taxes, if required pursuant to Section 15.7.  Each such


                                        -62-





         Note surrendered for conversion shall, unless the shares issuable
         on conversion are to be issued in the same name as the
         registration of such Note, be duly endorsed by, or be accompanied
         by instruments of transfer in form satisfactory to the Company
         duly executed by, the holder or his duly authorized attorney.

              As promptly as practicable after satisfaction of the
         requirements for conversion set forth above, subject to compliance
         with any restrictions on transfer if shares issuable on conversion
         are to be issued in a name other than that of the Noteholder (as
         if such transfer were a transfer of the Note or Notes (or portion
         thereof) so converted), the Company shall issue and shall deliver
         to such holder at the office or agency maintained by the Company
         for such purpose pursuant to Section 5.2, a certificate or
         certificates for the number of full shares of Common Stock
         issuable upon the conversion of such Note or portion thereof in
         accordance with the provisions of this Article and a check or cash
         in respect of any fractional interest in respect of a share of
         Common Stock arising upon such conversion, as provided in Section
         15.3.  In case any Note of a denomination greater than $1,000
         shall be surrendered for partial conversion, and subject to
         Section 2.3, the Company shall execute and the Trustee shall
         authenticate and deliver to the holder of the Note so surrendered,
         without charge to him, a new Note or Notes in authorized
         denominations in an aggregate principal amount equal to the
         unconverted portion of the surrendered Note.

              Each conversion shall be deemed to have been effected as to
         any such Note (or portion thereof) on the date on which the
         requirements set forth above in this Section 15.2 have been
         satisfied as to such Note (or portion thereof), and the person in
         whose name any certificate or certificates for shares of Common
         Stock shall be issuable upon such conversion shall be deemed to
         have become on said date the holder of record of the shares
         represented thereby; provided, however, that any such surrender on
         any date when the stock transfer books of the Company shall be
         closed shall constitute the person in whose name the certificates
         are to be issued as the record holder thereof for all purposes on
         the next succeeding day on which such stock transfer books are
         open, but such conversion shall be at the Conversion Price in
         effect on the date upon which such Note shall be surrendered.  

              Any Note or portion thereof surrendered for conversion during
         the period from the close of business on the record date for any
         interest payment date to the close of business on the Business Day
         next preceding the following interest payment date shall (unless
         such Note or portion thereof being converted shall have been
         called for redemption during the period from the close of business
         on such record date to the close of business on the second
         Business Day next succeeding the following interest payment date)


                                        -63-





         be accompanied by payment, in New York Clearing House funds or
         other funds acceptable to the Company, of an amount equal to the 
         interest payable on such interest payment date on the principal
         amount being converted; provided, however, that no such payment
         need be made if there shall exist at the time of conversion a
         default in the payment of interest on the Notes.  Except as
         provided above in this Section 15.2 or the second paragraph of
         Section 2.3, no adjustment shall be made for interest accrued on
         any Note converted or for dividends on any shares issued upon the
         conversion of such Note as provided in this Article.  

              Section 15.3  CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES.  No
         fractional shares of Common Stock or scrip representing fractional
         shares shall be issued upon conversion of Notes.  If more than one
         Note shall be surrendered for conversion at one time by the same
         holder, the number of full shares which shall be issuable upon
         conversion shall be computed on the basis of the aggregate
         principal amount of the Notes (or specified portions thereof to
         the extent permitted hereby) so surrendered.  If any fractional
         share of stock would be issuable upon the conversion of any Note
         or Notes, the Company shall make an adjustment and payment
         therefor in cash at the current market value thereof to the holder
         of Notes.  The current market value of a share of Common Stock
         shall be the Closing Price on the first Trading Day immediately
         preceding the day on which the Notes (or specified portions
         thereof) are deemed to have been converted.

              Section 15.4  CONVERSION PRICE.  The conversion price shall
         be as specified in the form of Note (herein called the "Conversion
         Price") attached as Exhibit A hereto, subject to adjustment as
         provided in this Article XV.

              Section 15.5  ADJUSTMENT OF CONVERSION PRICE.  The Conversion
         Price shall be adjusted from time to time by the Company as
         follows:

                   (a)  In case the Company shall hereafter pay a dividend
         or make a distribution to all holders of the outstanding Common
         Stock in shares of Common Stock, the Conversion Price in effect at
         the opening of business on the date following the date fixed for
         the determination of stockholders entitled to receive such
         dividend or other distribution shall be reduced by multiplying
         such Conversion Price by a fraction of which the numerator shall
         be the number of shares of Common Stock outstanding at the close
         of business on the date fixed for such determination and the
         denominator shall be the sum of such number of shares and the
         total number of shares constituting such dividend or other
         distribution, such reduction to become effective immediately after
         the opening of business on the day following the date fixed for
         such determination.  The Company will not pay any dividend or make


                                        -64-





         any distribution on shares of Common Stock held in the treasury of
         the Company.  If any dividend or distribution of the type
         described in this Section 15.5(a) is declared but not so paid or
         made, the Conversion Price shall again be adjusted to the
         Conversion Price which would then be in effect if such dividend or
         distribution had not been declared.

                   (b)  In case the Company shall issue rights or warrants
         to all holders of its outstanding shares of Common Stock entitling
         them (for a period expiring within 45 days after the date fixed
         for determination of stockholders entitled to receive such rights
         or warrants) to subscribe for or purchase shares of Common Stock
         at a price per share less than the Current Market Price (as
         defined below) on the date fixed for determination of stockholders
         entitled to receive such rights or warrants, the Conversion Price
         shall be adjusted so that the same shall equal the price
         determined by multiplying the Conversion Price in effect
         immediately prior to the date fixed for determination of
         stockholders entitled to receive such rights or warrants by a
         fraction of which the numerator shall be the number of shares of
         Common Stock outstanding at the close of business on the date
         fixed for determination of stockholders entitled to receive such
         rights and warrants plus the number of shares which the aggregate
         offering price of the total number of shares so offered would
         purchase at such Current Market Price, and of which the
         denominator shall be the number of shares of Common Stock
         outstanding at the close of business on the date fixed for
         determination of stockholders entitled to receive such rights and
         warrants plus the total number of additional shares of Common
         Stock offered for subscription or purchase.  Such adjustment shall
         be successively made whenever any such rights and warrants are
         issued, and shall become effective immediately after the opening
         of business on the day following the date fixed for determination
         of stockholders entitled to receive such rights or warrants.  To
         the extent that shares of Common Stock are not delivered after the
         expiration of such rights or warrants, the Conversion Price shall
         be readjusted to the Conversion Price which would then be in
         effect had the adjustments made upon the issuance of such rights
         or warrants been made on the basis of delivery of only the number
         of shares of Common Stock actually delivered.  In the event that
         such rights or warrants are not so issued, the Conversion Price
         shall again be adjusted to be the Conversion Price which would
         then be in effect if such date fixed for the determination of
         stockholders entitled to receive such rights or warrants had not
         been fixed.  In determining whether any rights or warrants entitle
         the holders to subscribe for or purchase shares of Common Stock at
         less than such Current Market Price, and in determining the
         aggregate offering price of such shares of Common Stock, there
         shall be taken into account any consideration received by the
         Company for such rights or warrants, the value of such


                                        -65-





         consideration, if other than cash, to be determined by the Board
         of Directors.

                   (c)  In case outstanding shares of Common Stock shall be
         subdivided into a greater number of shares of Common Stock, the
         Conversion Price in effect at the opening of business on the day
         following the day upon which such subdivision becomes effective
         shall be proportionately reduced, and conversely, in case
         outstanding shares of Common Stock shall be combined into a
         smaller number of shares of Common Stock, the Conversion Price in
         effect at the opening of business on the day following the day
         upon which such combination becomes effective shall be
         proportionately increased, such reduction or increase, as the case
         may be, to become effective immediately after the opening of
         business on the day following the day upon which such subdivision
         or combination becomes effective.

                   (d)  In case the Company shall, by dividend or
         otherwise, distribute to all holders of its Common Stock shares of
         any class of capital stock of the Company (other than any
         dividends or distributions to which Section 15.5(a) applies) or
         evidences of its indebtedness or assets (including securities, but
         excluding any rights or warrants referred to in Section 15.5(b),
         and excluding any dividend or distribution (x) in connection with
         the liquidation, dissolution or winding up of the Company, whether
         voluntary or involuntary, (y) paid exclusively in cash or (z)
         referred to in Section 15.5(a) (any of the foregoing hereinafter
         in this Section 15.5(d) called the "Securities")), then, in each
         such case (unless the Company elects to reserve such Securities
         for distribution to the Noteholders upon the conversion of the
         Notes so that any such holder converting Notes will receive upon
         such conversion, in addition to the shares of Common Stock to
         which such holder is entitled, the amount and kind of such
         Securities which such holder would have received if such holder
         had converted its Notes into Common Stock immediately prior to the
         Record Date (as defined in Section 15.5(h) for such distribution
         of the securities)), the Conversion Price shall be reduced so that
         the same shall be equal to the price determined by multiplying the
         Conversion Price in effect at the close of business on the Record
         Date with respect to such distribution by a fraction of which the
         numerator shall be the Current Market Price per share of the
         Common Stock on such Record Date less the fair market value (as
         determined by the Board of Directors, whose determination shall be
         conclusive, and described in a resolution of the Board of
         Directors) on the Record Date of the portion of the Securities so
         distributed applicable to one share of Common Stock and the
         denominator shall be the Current Market Price per share of the
         Common Stock, such reduction to become effective immediately prior
         to the opening of business on the day following such Record Date;
         provided, however, that in the event the then fair market value


                                        -66-





         (as so determined) of the portion of the Securities so distributed
         applicable to one share of Common Stock is equal to or greater
         than the Current Market Price of the Common Stock on the Record
         Date, in lieu of the foregoing adjustment, adequate provision
         shall be made so that each Noteholder shall have the right to
         receive upon conversion the amount of Securities such holder would
         have received had such holder converted each Note on the Record
         Date.  

              In the event that such dividend or distribution is not so
         paid or made, the Conversion Price shall again be adjusted to be
         the Conversion Price which would then be in effect if such
         dividend or distribution had not been declared.  If the Board of
         Directors determines the fair market value of any distribution for
         purposes of this Section 15.5(d) by reference to the actual or
         when issued trading market for any securities, it must in doing so
         consider the prices in such market over the same period used in
         computing the Current Market Price of the Common Stock.

              Each share of Common Stock issued upon conversion of Notes
         pursuant to this Article XV shall be entitled to receive the
         appropriate number of Rights, and the certificates representing
         the Common Stock issued upon such conversion shall bear such
         legends, in each case as provided by and subject to the terms of
         the Rights Plan as in effect at the time of such conversion
         (whether or not such Rights have separated from the Common Stock
         at the time of conversion).  In the event that the Company
         implements any new stockholders' rights plan, as amended,
         supplemented or modified from time to time (a "New Rights Plan"),
         such New Rights Plan shall provide that upon conversion of the
         Notes the holders will receive, in addition to the Common Stock
         issuable upon such conversion, the rights (whether or not such
         rights have separated from Common Stock at the time of the
         conversion) issuable pursuant to the New Rights Plan.

              Rights or warrants distributed by the Company to all holders
         of Common Stock entitling the holders thereof to subscribe for or
         purchase shares of the Company's capital stock (either initially
         or under certain circumstances), which rights or warrants, until
         the occurrence of a specified event or events ("Trigger Event"):
         (i) are deemed to be transferred with such shares of Common Stock;
         (ii) are not exercisable; and (iii) are also issued in respect of
         future issuances of Common Stock, shall be deemed not to have been
         distributed for purposes of this Section 15.5 (and no adjustment
         to the Conversion Price under this Section 15.5 will be required)
         until the occurrence of the earliest Trigger Event, whereupon
         such rights and warrants shall be deemed to have been distributed
         and an appropriate adjustment (if any is required) to the
         Conversion Price shall be made under this Section 15.5(d).  If any
         such right or warrant, including any such existing rights or


                                        -67-




         warrants distributed prior to the date of this Indenture, are
         subject to events, upon the occurrence of which such rights or
         warrants become exercisable to purchase different securities,
         evidences of indebtedness or other assets, then the date of the
         occurrence of any and each such event shall be deemed to be the
         date of distribution and record date with respect to new rights or
         warrants with such rights (and a termination or expiration of the
         existing rights or warrants without exercise by any of the holders
         thereof).  In addition, in the event of any distribution (or
         deemed distribution) of rights or warrants, or any Trigger Event
         or other event (of the type described in the preceding sentence)
         with respect thereto that was counted for purposes of calculating
         a distribution amount for which an adjustment to the Conversion
         Price under this Section 15.5 was made, (1) in the case of any
         such rights or warrants which shall all have been redeemed or
         repurchased without exercise by any holders thereof, the
         Conversion Price shall be readjusted upon such final redemption or
         repurchase to give effect to such distribution or Trigger Event,
         as the case may be, as though it were a cash distribution, equal
         to the per share redemption or repurchase price received by a
         holder or holders of Common Stock with respect to such rights
         or warrants (assuming such holder had retained such rights or
         warrants), made to all holders of Common Stock as of the date of
         such redemption or repurchase, and (2) in the case of such rights
         or warrants which shall have expired or been terminated without
         exercise by any holders thereof, the Conversion Price shall be
         readjusted as if such rights and warrants had not been issued.

              For purposes of this Section 15.5(d) and Sections 15.5(a) and
         (b), any dividend or distribution to which this Section 15.5(d) is
         applicable that also includes shares of Common Stock, or rights or
         warrants to subscribe for or purchase shares of Common Stock (or
         both), shall be deemed instead to be (1) a dividend or
         distribution of the evidences of indebtedness, assets or shares of
         capital stock other than such shares of Common Stock or rights or
         warrants (and any Conversion Price reduction required by this
         Section 15.5(d) with respect to such dividend or distribution
         shall then be made) immediately followed by (2) a dividend or
         distribution of such shares of Common Stock or such rights or
         warrants (and any further Conversion Price reduction required by
         Sections 15.5(a) and (b) with respect to such dividend or
         distribution shall then be made), except (A) the Record Date of
         such dividend or distribution shall be substituted as "the date
         fixed for the determination of stockholders entitled to receive
         such dividend or other distribution" and "the date fixed for such
         determination" within the meaning of Sections 15.5(a) and (b) and
         (B) any shares of Common Stock included in such dividend or
         distribution shall not be deemed "outstanding at the close of
         business on the date fixed for such determination" within
         the meaning of Section 15.5(a). 


                                        -68-





                   (e)  In case the Company shall, by dividend or
         otherwise, distribute to all holders of its Common Stock cash
         (excluding (x) any quarterly cash dividend on the Common Stock to
         the extent the aggregate cash dividend per share of Common Stock
         in any fiscal quarter does not exceed the greater of (A) the
         amount per share of Common Stock of the next preceding quarterly
         cash dividend on the Common Stock to the extent that such
         preceding quarterly dividend did not require any adjustment of the
         Conversion Price pursuant to this Section 15.5(e) (as adjusted to
         reflect subdivisions or combinations of the Common Stock), and (B)
         3.75% of the arithmetic average of the Closing Prices (determined
         as set forth in Section 15.5(h)) during the ten consecutive
         Trading Days (as defined in Section 15.5(h)) immediately prior to
         the date of declaration of such dividend, and (y) any dividend or
         distribution in connection with the liquidation, dissolution or
         winding up of the Company, whether voluntary or involuntary),
         then, in such case, the Conversion Price shall be reduced so that
         the same shall equal the price determined by multiplying the
         Conversion Price in effect immediately prior to the close of
         business on the Record Date for such dividend or distribution by a
         fraction of which the numerator shall be the Current Market Price
         of the Common Stock on the Record Date less the amount of cash so
         distributed (and not excluded as provided above) applicable to one
         share of Common Stock and the denominator shall be such Current
         Market Price of the Common Stock, such reduction to be effective
         immediately prior to the opening of business on the day following
         the Record Date; provided, however, that in the event the portion
         of the cash so distributed applicable to one share of Common Stock
         is equal to or greater than the Current Market Price of the Common
         Stock on the Record Date, in lieu of the foregoing adjustment,
         adequate provision shall be made so that each Noteholder shall
         have the right to receive upon conversion the amount of cash such
         holder would have received had such holder converted each Note on
         the Record Date.  In the event that such dividend or distribution
         is not so paid or made, the Conversion Price shall again be
         adjusted to be the Conversion Price which would then be in effect
         if such dividend or distribution had not been declared.  If any
         adjustment is required to be made as set forth in this Section
         15.5(e) as a result of a distribution that is a quarterly
         dividend, such adjustment shall be based upon the amount by which
         such distribution exceeds the amount of the quarterly cash
         dividend permitted to be excluded pursuant hereto.  If an
         adjustment is required to be made as set forth in this Section
         15.5(e) above as a result of a distribution that is not a
         quarterly dividend, such adjustment shall be based upon the full
         amount of the distribution. 

                   (f)  In case a tender or exchange offer made by the
         Company or any subsidiary of the Company for all or any portion of
         the Common Stock shall expire and such tender or exchange offer


                                        -69-





         (as amended upon the expiration thereof) shall require the payment
         to stockholders of consideration per share of Common Stock having
         a fair market value (as determined by the Board of Directors,
         whose determination shall be conclusive and described in a
         resolution of the Board of Directors) that, as of the last time
         (the "Expiration Time") tenders or exchanges may be made pursuant
         to such tender or exchange offer (as it may be amended) exceeds
         the Current Market Price of the Common Stock on the Trading Day
         next succeeding the Expiration Time, the Conversion Price shall be
         reduced so that the same shall equal the price determined by
         multiplying the Conversion Price in effect immediately prior to
         the Expiration Time by a fraction of which the numerator shall be
         the number of shares of Common Stock outstanding (including any
         tendered or exchanged shares) on the Expiration Time multiplied by
         the Current Market Price of the Common Stock on the Trading Day
         next succeeding the Expiration Time and the denominator shall be
         the sum of (x) the fair market value (determined as aforesaid) of
         the aggregate consideration payable to shareholders based on the
         acceptance (up to any maximum specified in the terms of the tender
         or exchange offer) of all shares validly tendered or exchanged and
         not withdrawn as of the Expiration Time (the shares deemed so
         accepted, up to any such maximum, being referred to as the
         "Purchased Shares") and (y) the product of the number of shares of
         Common Stock outstanding (less any Purchased Shares) on the
         Expiration Time and the Current Market Price of the Common Stock
         on the Trading Day next succeeding the Expiration Time, such
         reduction to become effective immediately prior to the opening of
         business on the day following the Expiration Time.  In the event
         that the Company is obligated to purchase shares pursuant to any
         such tender or exchange offer, but the Company is permanently
         prevented by applicable law from effecting any such purchases or
         all such purchases are rescinded, the Conversion Price shall again
         be adjusted to be the Conversion Price which would then be in
         effect if such tender or exchange offer had not been made.  

                   (g)  In case of a tender or exchange offer made by a
         person other than the Company or any subsidiary of the Company for
         an amount which increases the offeror's ownership of Common Stock
         to more than 25% of the Common Stock outstanding and shall involve
         the payment by such person of consideration per share of Common
         Stock having a fair market value (as determined by the Board of
         Directors, whose determination shall be conclusive, and described
         in a resolution of the Board of Directors) at the last time (the
         "Expiration Time") tenders or exchanges may be made pursuant to
         such tender or exchange offer (as it shall have been amended) that
         exceeds the Current Market Price of the Common Stock on the
         Trading Day next succeeding the Expiration Time, and in which, as
         of the Expiration Time the Board of Directors is not recommending
         rejection of the offer, the Conversion Price shall be reduced so
         that the same shall equal the price determined by multiplying the


                                        -70-





         Conversion Price in effect immediately prior to the Expiration
         Time by a fraction of which the numerator shall be the number of
         shares of Common Stock outstanding (including any tendered or
         exchanged shares) on the Expiration Time multiplied by the current
         Market Price of the Common Stock on the Trading Day next
         succeeding the Expiration Time and the denominator shall be the
         sum of (x) the fair market value (determined as aforesaid) of the
         aggregate consideration payable to stockholders based on the
         acceptance (up to any maximum specified in the terms of the tender
         or exchange offer) of all shares validly tendered or exchanged and
         not withdrawn as of the Expiration Time (the shares deemed so
         accepted, up to any such maximum, being referred to as the
         "Purchased Shares") and (y) the product of the number of shares of
         Common Stock outstanding (less any Purchased Shares) on the
         Expiration Time and the Current Market Price of the Common Stock
         on the Trading Day next succeeding the Expiration Time, such
         reduction to become effective as of immediately prior to the
         opening of business on the day following the Expiration Time.  In
         the event that such person is obligated to purchase shares
         pursuant to any such tender or exchange offer, but such person is
         permanently prevented by applicable law from effecting any such
         purchases or all such purchases are rescinded, the Conversion
         Price shall again be adjusted to be the Conversion Price which
         would then be in effect if such tender or exchange offer had not
         been made.  Notwithstanding the foregoing, the adjustment
         described in this Section 15.5(g) shall not be made if, as of the
         Expiration Time, the offering documents with respect to such offer
         disclose a plan or intention to cause the Company to engage in any
         transaction described in Article XII. 

                   (h)  For purposes of this Section 15.5, the following
         terms shall have the meaning indicated:

                        (1)  "Closing Price" with respect to any securities
         on any day shall mean the closing sale price regular way on such
         day or, in case no such sale takes place on such day, the average
         of the reported closing bid and asked prices, regular way, in each
         case on the New York Stock Exchange, or, if such security is not
         listed or admitted to trading on such Exchange, on the principal
         national security exchange or quotation system on which such
         security is quoted or listed or admitted to trading, or, if not
         quoted or listed or admitted to trading on any national securities
         exchange or quotation system, the average of the closing bid and
         asked prices of such security on the over-the-counter market on
         the day in question as reported by the National Quotation Bureau
         Incorporated, or a similar generally accepted reporting service,
         or if not so available, in such manner as furnished by any New
         York Stock Exchange member firm selected from time to time by the
         Board of Directors for that purpose, or a price determined in good
         faith by the Board of Directors or, to the extent permitted by


                                        -71-





         applicable law, a duly authorized committee thereof, whose
         determination hall be conclusive.

                        (2)  "Current Market Price" shall mean the average
         of the daily Closing Prices per share of Common Stock for the ten
         consecutive Trading Days immediately prior to the date in
         question; provided, however, that (1) if the "ex" date (as
         hereinafter defined) for any event (other than the issuance or
         distribution or Repurchase Event requiring such computation) that
         requires an adjustment to the Conversion Price pursuant to Section
         15.5(a), (b), (c), (d), (e), (f) or (g) occurs during such ten
         consecutive Trading Days, the Closing Price for each Trading Day
         prior to the "ex" date for such other event shall be adjusted by
         multiplying such Closing Price by the same fraction by which the
         Conversion Price is so required to be adjusted as a result of such
         other event, (2) if the "ex" date for any event (other than the
         issuance, distribution or Repurchase Event requiring such
         computation) that requires an adjustment to the Conversion Price
         pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs
         on or after the "ex" date for the issuance or distribution
         requiring such computation and prior to the day in question, the
         Closing Price for each Trading Day on and after the "ex" date for
         such other event shall be adjusted by multiplying such Closing
         Price by the reciprocal of the fraction by which the Conversion
         Price is so required to be adjusted as a result of such other
         event, and (3) if the "ex" date for the issuance, distribution or
         Repurchase Date requiring such computation is prior to the day in
         question, after taking into account any adjustment required
         pursuant to clause (1) or (2) of this proviso, the Closing Price
         for each Trading Day on or after such "ex" date shall be adjusted
         by adding thereto the amount of any cash and the fair market value
         (as determined by the Board of Directors or, to the extent
         permitted by applicable law, a duly authorized committee thereof
         in a manner consistent with any determination of such value for
         purposes of Section 15.5(d) or (f), whose determination shall be
         conclusive and described in a resolution of the Board of Directors
         or such duly authorized committee thereof, as the case may be) of
         the evidences of indebtedness, shares of capital stock or assets
         being distributed applicable to one share of Common Stock as of
         the close of business on the day before such "ex" date.  For
         purposes of any computation under Section 15.5(f), the Current
         Market Price of the Common Stock on any date shall be deemed to be
         the average of the daily Closing Prices per share of Common Stock
         for such day and the next two succeeding Trading Days; provided,
         however, that if the "ex" date for any event (other than the
         tender or exchange offer requiring such computation) that requires
         an adjustment to the Conversion Price pursuant to Section 15.5(a),
         (b), (c), (d), (e), (f) or (g) occurs on or after the Expiration
         Time for the tender or exchange offer requiring such computation
         and prior to the day in question, the Closing Price for each


                                        -72-





         Trading Day on and after the "ex" date for such other event shall
         be adjusted by multiplying such Closing Price by the reciprocal of
         the fraction by which the Conversion Price is so required to be
         adjusted as a result of such other event.  For purposes of this
         paragraph, the term "ex" date, (1) when used with respect to any
         issuance or distribution, means the first date on which the Common
         Stock trades regular way on the relevant exchange or in the
         relevant market from which the Closing Price was obtained without
         the right to receive such issuance or distribution, (2) when used
         with respect to any subdivision or combination of shares of Common
         Stock, means the first date on which the Common Stock trades
         regular way on such exchange or in such market after the time at
         which such subdivision or combination becomes effective, and (3)
         when used with respect to any tender or exchange offer means the
         first date on which the Common Stock trades regular way on such
         exchange or in such market after the Expiration Time of such
         offer. 

                        (3)  "fair market value" shall mean the amount
         which a willing buyer would pay a willing seller in an arm's
         length transaction. 

                        (4)  "Record Date" shall mean, with respect to any
         dividend, distribution or other transaction or event in which the
         holders of Common Stock have the right to receive any cash,
         securities or other property or in which the Common Stock (or
         other applicable security) is exchanged for or converted into any
         combination of cash, securities or other property, the date fixed
         for determination of shareholders entitled to receive such cash,
         securities or other property (whether such date is fixed by the
         Board of Directors or by statute, contract or otherwise).

                        (5)  "Trading Day" shall mean (x) if the applicable
         security is listed or admitted for trading on the New York Stock
         Exchange or another national security exchange, a day on which the
         New York Stock Exchange or another national security exchange is
         open for business or (y) if the applicable security is quoted on
         the Nasdaq National Market, a day on which trades may be made on
         thereon or (z) if the applicable security is not so listed,
         admitted for trading or quoted, any day other than a Saturday or
         Sunday or a day on which banking institutions in the State of New
         York are authorized or obligated by law or executive order to
         close. 

                   (i)  The Company may make such reductions in the
         Conversion Price, in addition to those required by Sections 15.5
         (a), (b), (c),(d), (e), (f) and (g) as the Board of Directors
         considers to be advisable to avoid or diminish any income tax to
         holders of Common Stock or rights to purchase Common Stock
         resulting from any dividend or distribution of stock (or rights to


                                        -73-





         acquire stock) or from any event treated as such for income tax
         purposes.  To the extent permitted by applicable law, the Company
         from time to time may reduce the Conversion Price by any amount
         for any period of time if the period is at least twenty (20) days,
         the reduction is irrevocable during the period and the Board of
         Directors shall have made a determination that such reduction
         would be in the best interests of the Company, which determination
         shall be conclusive.  Whenever the Conversion Price is reduced
         pursuant to the preceding sentence, the Company shall mail to
         holders of record of the Notes a notice of the reduction at least
         fifteen (15) days prior to the date the reduced Conversion Price
         takes effect, and such notice shall state the reduced Conversion
         Price and the period during which it will be in effect. 

                   (j)  No adjustment in the Conversion Price shall be
         required unless such adjustment would require an increase or
         decrease of at least 1% in such price; provided, however, that any
         adjustments which by reason of this Section 15.5(j) are not
         required to be made shall be carried forward and taken into
         account in any subsequent adjustment.  All calculations under this
         Article XV shall be made by the Company and shall be made to the
         nearest cent or to the nearest one hundredth of a share, as the
         case may be.  No adjustment need be made for rights to purchase
         Common Stock pursuant to a Company plan for reinvestment of
         dividends or interest.  To the extent the Notes become convertible
         into cash, assets, property or securities (other than capital
         stock of the Company), no adjustment need be made thereafter as to
         the cash, assets, property or such securities.  Interest will not
         accrue on the cash.

                   (k)  Whenever the Conversion Price is adjusted as herein
         provided, the Company shall promptly file with the Trustee and any
         conversion agent other than the Trustee an Officers' Certificate
         setting forth the Conversion Price after such adjustment and
         setting forth a brief statement of the facts requiring such
         adjustment. Promptly after delivery of such certificate, the
         Company shall prepare a notice of such adjustment of the
         Conversion Price setting forth the adjusted Conversion Price and
         the date on which each adjustment becomes effective and shall mail
         such notice of such adjustment of the Conversion Price to the
         holder of each Note at his last address appearing on the Note
         register provided for in Section 2.5 of this Indenture, within 20
         days after execution thereof.  Failure to deliver such notice
         shall not affect the legality or validity of any such adjustment.

                   (l)  In any case in which this Section 15.5 provides
         that an adjustment shall become effective immediately after a
         record date for an event, the Company may defer until the
         occurrence of such event (i) issuing to the holder of any Note
         converted after such record date and before the occurrence of such


                                        -74-





         event the additional shares of Common Stock issuable upon such
         conversion by reason of the adjustment required by such event over
         and above the Common Stock issuable upon such conversion before
         giving effect to such adjustment and (ii) paying to such holder
         any amount in cash in lieu of any fraction pursuant to Section
         15.3.

                   (m)  For purposes of this Section 15.5, the number of
         shares of Common Stock at any time outstanding shall not include
         shares held in the treasury of the Company but shall include
         shares issuable in respect of scrip certificates issued in lieu of
         fractions of shares of Common Stock.  The Company will not pay any
         dividend or make any distribution on shares of Common Stock held
         in the treasury of the Company.

              Section 15.6  EFFECT OF RECLASSIFICATION, CONSOLIDATION,
         MERGER OR SALE.  If any of the following events occur, namely (i)
         any reclassification or change of the outstanding shares of Common
         Stock (other than a subdivision or combination to which Section
         15.5(c) applies), (ii) any consolidation, merger or combination of
         the Company with another corporation as a result of which holders
         of Common Stock shall be entitled to receive stock, securities or
         other property or assets (including cash) with respect to or in
         exchange for such Common Stock, or (iii) any sale or conveyance of
         the properties and assets of the Company as, or substantially as,
         an entirety to any other corporation as a result of which holders
         of Common Stock shall be entitled to receive stock, securities or
         other property or assets (including cash) with respect to or in
         exchange for such Common Stock, then the Company or the successor
         or purchasing corporation, as the case may be, shall execute with
         the Trustee a supplemental indenture (which shall comply with the
         Trust Indenture Act as in force at the date of execution of such
         supplemental indenture) providing that such Note shall be
         convertible into the kind and amount of shares of stock and other
         securities or property or assets (including cash) receivable upon
         such reclassification, change, consolidation, merger, combination,
         sale or conveyance by a holder of a number of shares of Common
         Stock issuable upon conversion of such Notes (assuming, for such
         purposes, a sufficient number of authorized shares of Common Stock
         available to convert all such Notes) immediately prior to such
         reclassification, change, consolidation, merger, combination, sale
         or conveyance assuming such holder of Common Stock did not
         exercise his rights of election, if any, as to the kind or amount
         of securities, cash or other property receivable upon such
         consolidation, merger, statutory exchange, sale or conveyance
         (provided that, if the kind or amount of securities, cash or other
         property receivable upon such consolidation, merger, statutory
         exchange, sale or conveyance is not the same for each share of
         Common Stock in respect of which such rights of election shall not
         have been exercised ("nonelecting share")), then for the purposes


                                        -75-





         of this Section 15.6 the kind and amount of securities, cash or
         other property receivable upon such consolidation, merger,
         statutory exchange, sale or conveyance for each non-electing share
         shall be deemed to be the kind and amount so receivable per share
         by a plurality of the non-electing shares.  Such supplemental
         indenture shall provide for adjustments which shall be as nearly
         equivalent as may be practicable to the adjustments provided for
         in this Article.

              The Company shall cause notice of the execution of such
         supplemental indenture to be mailed to each holder of Notes, at
         his address appearing on the Note register provided for in Section
         2.5 of this Indenture, within twenty (20) days after execution
         thereof.   Failure to deliver such notice shall not affect the
         legality or validity of such supplemental indenture.

              The above provisions of this Section shall similarly apply to
         successive reclassifications, changes, consolidations, mergers,
         combinations, sales and conveyances.  

              If this Section 15.6 applies to any event or occurrence,
         Section 15.5 shall not apply.

              Section 15.7  TAXES ON SHARES ISSUED.  The issue of stock
         certificates on conversions of Notes shall be made without charge
         to the converting Noteholder for any tax in respect of the issue
         thereof.  The Company shall not, however, be required to pay any
         tax which may be payable in respect of any transfer involved in
         the issue and delivery of stock in any name other than that of the
         holder of any Note converted, and the Company shall not be
         required to issue or deliver any such stock certificate unless and
         until the person or persons requesting the issue 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 15.8  RESERVATION OF SHARES; SHARES TO BE FULLY PAID;
         COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS; LISTING OF COMMON
         STOCK.  The Company shall reserve, free from preemptive rights,
         out of its authorized but unissued shares or shares held in
         treasury, sufficient shares of Common Stock to provide for the
         conversion of the Notes from time to time as such Notes are
         presented for conversion.  

              Before taking any action which would cause an adjustment
         reducing the Conversion Price below the then par value, if any, of
         the shares of Common Stock issuable upon conversion of the Notes,
         the Company will take all corporate action which may, in the
         opinion of its counsel, be necessary in order that the Company may



                                        -76-





         validly and legally issue shares of such Common Stock at such
         adjusted Conversion Price.  

              The Company covenants that all shares of Common Stock which
         may be issued upon conversion of Notes will upon issue be fully
         paid and non-assessable by the Company and free from all taxes,
         liens and charges with respect to the issue thereof.  

              The Company covenants that if any shares of Common Stock to
         be provided for the purpose of conversion of Notes hereunder
         require registration with or approval of any governmental
         authority under any federal or state law before such shares may be
         validly issued upon conversion, the Company will in good faith and
         as expeditiously as possible endeavor to secure such registration
         or approval, as the case may be.  

              The Company further covenants that if at any time the Common
         Stock shall be listed on the Nasdaq National Market or any other
         national securities exchange or automated quotation system the
         Company will, if permitted by the rules of such exchange or
         automated quotation system, list and keep listed, so long as the
         Common Stock shall be so listed on such exchange or automated
         quotation system, all Common Stock issuable upon conversion of the
         Notes.

              Section 15.9  RESPONSIBILITY OF TRUSTEE. The Trustee and any
         other conversion agent shall not at any time be under any duty or
         responsibility to any holder of Notes to determine whether any
         facts exist which may require any adjustment of the Conversion
         Price, or with respect to the nature or extent or calculation 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.  The Trustee and any other
         conversion agent shall not be accountable with respect to the
         validity or value (or the kind or amount) of any shares of Common
         Stock, or of any securities or property, which may at any time be
         issued or delivered upon the conversion of any Note; and the
         Trustee and any other conversion agent make no representations
         with respect thereto.  Subject to the provisions of Section 8.1,
         neither the Trustee nor any conversion agent shall be responsible
         for any failure of the Company to issue, transfer or deliver any
         shares of Common Stock or stock certificates or other securities
         or property or cash upon the surrender of any Note for the purpose
         of conversion or to comply with any of the duties,
         responsibilities or covenants of the Company contained in this
         Article.  Without limiting the generality of the foregoing,
         neither the Trustee nor any conversion agent shall be under any
         responsibility to determine the correctness of any provisions
         contained in any supplemental indenture entered into pursuant to
         Section 15.6 relating either to the kind or amount of shares of


                                        -77-





         stock or securities or property (including cash) receivable by
         Noteholders upon the conversion of their Notes after any event
         referred to in such Section 15.6 or to any adjustment to be made
         with respect thereto, but, subject to the provisions of Section
         8.1, may accept as conclusive evidence of the correctness of any
         such provisions, and shall be protected in relying upon, the
         Officers' Certificate (which the Company shall be obligated to
         file with the Trustee prior to the execution of any such
         supplemental indenture) with respect thereto.

              Section 15.10 NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.  In
         case:

                   (a) the Company shall declare a dividend (or any other
         distribution) on its Common Stock that would require an adjustment
         in the Conversion Price pursuant to Section 15.5; or

                   (b) the Company shall authorize the granting to the
         holders of its Common Stock of rights or warrants to subscribe for
         or purchase any share of any class or any other rights or warrants
         (other than the Rights granted pursuant to the Rights Plan,
         provided that the holders of the Notes receive the same notice
         received by all holders of Common Stock regarding such grant in
         accordance with the applicable notice provisions of the Rights
         Plan); or 

                   (c) of any reclassification or reorganization of the
         Common Stock of the Company (other than a subdivision or
         combination of its outstanding Common Stock, or a change in par
         value, or from par value to no par value, or from no par value to
         par value), or of any consolidation or merger to which the Company
         is a party and for which approval of any 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; Company shall cause to
         be filed with the Trustee and to be mailed to each holder of Notes
         at his address appearing on the Note register provided for in

         event at least fifteen (15) days prior to the applicable date
         hereinafter specified, a notice stating (x) the date on which a
         record is to be taken for the purpose of such dividend,
         distribution, rights or warrants, or, if a record is not to be

         to be entitled to such dividend, distribution, rights or warrants
         are to be determined, or (y) the date on which such
         reclassification, consolidation, merger, sale, transfer,
         dissolution, liquidation or winding-up is expected to become

         their Common Stock for securities or other property deliverable
         upon such reclassification, consolidation, merger, sale, transfer,
         dissolution, liquidation or winding-up.  Failure to give such
         notice, or any defect therein, shall not affect the legality or
         validity of such dividend, distribution, reclassification,
         consolidation, merger, sale, transfer, dissolution, liquidation or
         winding-up.

                             REPURCHASE OF NOTES AT THE
                        OPTION OF THE HOLDER UPON REPURCHASE EVENT


              Section 16.1  RIGHT TO REQUIRE REPURCHASE.  In the event that
         a Repurchase Event (as hereinafter defined) shall occur, then each
         holder shall have the right, at the holder's option, to require
         the Company to repurchase, and upon the exercise of such right the
         Company shall repurchase, all of such holder's Notes, or any
         portion of the principal amount thereof that is an integral
         multiple of U.S. $1,000 (provided that no single Note may be
         repurchased in part unless the portion of the principal amount of
         such Note to be outstanding after such repurchase is equal to U.S.
         $1,000 or integral multiples of U.S. $1,000), on the date (the
         "Repurchase Date") that is 30 days after the date of the Company
         Notice (as defined in Section 16.2) for cash at a purchase price
         equal to 100% of the principal amount plus interest accrued and
         unpaid interest to, but excluding, the Repurchase Date (the
         "Repurchase Price"); provided that if the Repurchase Date is March
         15 or September 15, then the interest payable on such date shall
         be paid to the holder of record of the Note on the next preceding
         March 1 or September 1, respectively. Whenever in this Indenture
         there is a reference, in any context, to the principal of any Note
         as of any time, such reference shall be deemed to include
         reference to the Repurchase Price payable in respect of such Note
         to the extent that such Repurchase Price is, was or would be so
         payable at such time, and express mention of the Repurchase Price
         in any provision of this Indenture shall not be construed as
         excluding the Repurchase Price in those provisions of this
         Indenture when such express mention is not made.

              Section 16.2  NOTICES; METHOD OF EXERCISING REPURCHASE RIGHT,
         ETC.  

                   (a) Unless the Company shall have theretofore called for
         redemption all of the outstanding Notes pursuant to Article III,
         on or before the 30th day after the occurrence of a Repurchase
         Event, the Company or, at the request of the Company on or before


                                        -79-





         the 15th day after such occurrence, the Trustee shall give to all
         holders of Notes notice (the "Company Notice") of the occurrence
         of the Repurchase Event and of the repurchase right set forth
         herein arising as a result thereof.  The Company shall also
         deliver a copy of such notice of a repurchase right to the
         Trustee.  

                  Each notice of a repurchase right shall state:  

                        (1)  the Repurchase Date, 

                        (2)  the date by which the repurchase right must be
         exercised,

                        (3)  the Repurchase Price, 

                        (4)  a description of the procedure which a holder
         must follow to exercise a repurchase right, 

                        (5)  that on the Repurchase Date the Repurchase
         Price will become due and payable upon each such Note designated
         by the holder to be repurchased, and that interest thereon shall
         cease to accrue on and after said date, 

                        (6)  the Conversion Price, the date on which the
         right to convert the Notes to be repurchased will terminate, the
         places where such Notes may be surrendered for conversion, and a
         statement that if the holder wishes to convert any Notes or any
         portion thereof after having tendered them for repurchase, such
         written notice of exercise of the right to require repurchase of
         such Note or portion thereof to be repurchased must first be
         withdrawn by delivery of a proper notice to the Trustee, and 

                        (7)  the place or places where such Notes are to be
         surrendered for payment of the Repurchase Price and accrued
         interest, if any.  No failure of the Company to give the foregoing
         notices or defect therein shall limit any holder's right to
         exercise a repurchase right or affect the validity of the
         proceedings for the repurchase of Notes.  

              If any of the foregoing provisions or other provisions of
         this Article are inconsistent with applicable law, such law shall
         govern.  

                   (b) To exercise a repurchase right, a holder shall
         deliver to the Trustee or any paying agent on or before the 30th
         day after the date of the Company Notice (i) written notice of the
         holder's exercise of such right, which notice shall set forth the
         name of the holder, the principal amount of the Notes to be
         repurchased (and, if any Note is to repurchased in part, the


                                        -80-





         serial number thereof, the portion of the principal amount thereof
         to be repurchased and the name of the Person in which the portion
         thereof to remain outstanding after such repurchase is to be
         registered) and a statement that an election to exercise the
         repurchase right is being made thereby, and (ii) the Notes with
         respect to which the repurchase right is being exercised.  

                   (c) In the event a repurchase right shall be exercised
         in accordance with the terms hereof, the Company shall pay or
         cause to be paid to the Trustee or the paying agent the Repurchase
         Price in cash, for payment to the holder on the Repurchase Date.  

                   (d) If any Note (or portion thereof) surrendered for
         repurchase (in accordance herewith and not properly withdrawn)
         shall not be so paid on the Repurchase Date, the principal amount
         of such Note (or portion thereof, as the case may be) shall, until
         paid, bear interest from the Repurchase Date at the rate of 6 3/4%
         per annum, and each Note shall remain convertible into Common
         Stock until the principal of such Note (or portion thereof, as the
         case may be) shall have been paid or duly provided for.

                   (e) Any Note which is to be repurchased only in part
         shall be surrendered to the Trustee (with, if the Company or the
         Trustee so requires, due endorsement by, or a written instrument
         of transfer in form satisfactory to the Company and the Trustee
         duly executed by, the holder thereof or his attorney duly
         authorized in writing), and the Company shall execute, and the
         Trustee shall authenticate and deliver to the holder of such Note
         without service charge, a new Note or Notes, containing identical
         terms and conditions, each in an authorized denomination in
         aggregate principal amount equal to and in exchange for the
         unrepurchased portion of the principal of the Note so surrendered.

         Article XVI,

         of the Company, or any employee benefit plan of the Company or any
         such subsidiary, is or becomes the beneficial owner, directly or


                                        -81-





         indirectly, through a purchase or other acquisition transaction or
         series of transactions (other than a merger or consolidation
         involving the Company), of shares of capital stock of the Company

         ten consecutive Trading Days ending immediately before the
         Repurchase Event shall equal or exceed 105% of the Conversion

         transaction or transactions such Notes become convertible solely
         into such common stock.

         contents and the titles and headings of the articles and sections
         of this Indenture have been inserted for convenience of reference
         only, are not to be considered a part hereof, and shall in no way
         modify or restrict any of the terms or provisions hereof.  

              Section 17.11 AUTHENTICATING AGENT.  The Trustee may appoint
         an authenticating agent which shall be authorized to act on its
         behalf and subject to its direction in the authentication and
         delivery of Notes in connection with the original issuance thereof
         and transfers and exchanges of Notes hereunder, including under
         Sections 2.4, 2.5, 2.6, 2.7, 3.3, 15.2 and 16.2, as fully to all
         intents and purposes as though the authenticating agent had been
         expressly authorized by this Indenture and those Sections to
         authenticate and deliver Notes.  For all purposes of this
         Indenture, the authentication and delivery of Notes by the
         authenticating agent shall be deemed to be authentication and
         delivery of such Notes "by the Trustee" and a certificate of
         authentication executed on behalf of the Trustee by an
         authenticating agent shall be deemed to satisfy any requirement
         hereunder or in the Notes for the Trustee's certificate of
         authentication.  Such authenticating agent shall at all times be a
         person eligible to serve as trustee hereunder pursuant to Section
         8.9.  

              Any corporation into which any authenticating agent may be
         merged or converted or with which it may be consolidated, or any
         corporation resulting from any merger, consolidation or conversion
         to which any authenticating agent shall be a party, or any
         corporation succeeding to the corporate trust business of any
         authenticating agent, shall be the successor of the authenticating
         agent hereunder, if such successor corporation is otherwise
         eligible under this Section 17.11, without the execution or filing
         of any paper or any further act on the part of the parties hereto
         or the authenticating agent or such successor corporation.


                                        -85-





              Any authenticating agent may at any time resign by giving
         written notice of resignation to the Trustee and to the Company.
         The Trustee may at any time terminate the agency of any
         authenticating agent by giving written notice of termination to
         such authenticating agent and to the Company.  Upon receiving such
         a notice of resignation or upon such a termination, or in case at
         any time any authenticating agent shall cease to be eligible under
         this Section, the Trustee shall promptly appoint a successor
         authenticating agent (which may be the Trustee), shall give
         written notice of such appointment to the Company and shall mail
         notice of such appointment to all holders of Notes as the names
         and addresses of such holders appear on the Note register.  

              The Trustee agrees to pay to the authenticating agent from
         time to time reasonable compensation for its services (to the
         extent pre-approved by the Company in writing), and the 
         Trustee shall be entitled to be reimbursed for such pre-approved
         payments, subject to Section 8.6.

              The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this
         Section 17.11 shall be applicable to any authenticating agent.

         The City of New York, or, at the option of the holder of this
         Note, at the Corporate Trust Office, in such coin or currency of
         the United States of America as at the time of payment shall be
         legal tender for the payment of public and private debts, and to

         be, next preceding the date of this Note to which interest has
         been paid or duly provided for, unless the date hereof is a date
         to which interest has been paid or duly provided for, in which
         case from the date of this Note, or unless no interest has been
         paid or duly provided for on the Notes, in which case from March

         registered address of such person; provided that, with respect to
         any holder of Notes with an aggregate principal amount equal to or

         paid by wire transfer (the costs of such wire transfer to be borne
         by the Company) in immediately available funds in accordance with
         the wire transfer instructions supplied by such holder to the
         Trustee and paying agent (if different from the Trustee).

                        6 3/4% CONVERTIBLE SUBORDINATED NOTE DUE 2001


              This Note is one of a duly authorized issue of Notes of the
         Company, designated as its 6 3/4% Convertible Subordinated Notes
         due 2001 (herein called the "Notes"), limited to the aggregate
         principal amount of $46,000,000 all issued or to be issued under
         and pursuant to an indenture dated as of March 13, 1996 (herein
         called the "Indenture"), between the Company and State Street Bank
         and Trust Company, as trustee (herein called the "Trustee"), to
         which Indenture and all indentures supplemental thereto reference
         is hereby made for a description of the rights, limitations of
         rights, obligations, duties and immunities thereunder of the
         Trustee, the Company and the holders of the Notes.

              In case an Event of Default, as defined in the Indenture,
         shall have occurred and be continuing, the principal of and
         accrued interest on all Notes may be declared, and upon said
         declaration shall become, due and payable, in the manner, with the
         effect and subject to the conditions provided in the Indenture.

              The Indenture contains provisions permitting the Company and
         the Trustee, with the consent of the holders of not less than a
         majority in aggregate principal amount of the Notes at the time
         outstanding, evidenced as in the Indenture provided, to execute
         supplemental indentures adding any provisions to or changing in
         any manner or eliminating any of the provisions of the Indenture
         or of any supplemental indenture or modifying in any manner the
         rights of the holders of the Notes; provided, however, that no
         such supplemental indenture shall (i) extend the fixed maturity of
         any Note, or reduce the rate or extend the time of payment of
         interest thereon, or reduce the principal amount thereof or
         premium, if any, thereon, or reduce any amount payable on
         redemption thereof, or impair the right of any Noteholder to
         institute suit for the payment thereof, or make the principal
         thereof or interest or premium, if any, thereon payable in any
         coin or currency other than that provided in the Note, or modify
         the provisions of the Indenture with respect to the subordination
         of the Notes in a manner adverse to the Noteholders in any
         material respect, or change the obligation of the Company to make
         repurchase of any Note upon the happening of a Repurchase Event in
         a manner adverse to the holder of the Notes, or impair the right
         to convert the Notes into Common Stock subject to the terms set
         forth in the Indenture, including Section 15.6 thereof, without
         the consent of the holder of each Note so affected or (ii) reduce
         the aforesaid percentage of Notes, the holders of which are
         required to consent to any such supplemental indenture, without
         the consent of the holders of all Notes then outstanding.  It is
         also provided in the Indenture that the holders of a majority in
         aggregate principal amount of the Notes at the time outstanding
         may on behalf of the holders of all of the Notes waive any past
         default or Event of Default under the Indenture and its
         consequences except a default in the payment of interest or any
         premium on or the principal of any of the Notes, a default in the
         payment of redemption price pursuant to Article III or repurchase
         price pursuant to Article XVI, a failure by the Company to convert
         any Notes into Common Stock of the Company or a default in respect
         of a covenant or provisions hereof which under Article XI cannot
         be modified or amended without the consent of holders of all Notes
         then outstanding.  Any such consent or waiver by the holder of
         this Note (unless revoked as provided in the Indenture) shall be
         conclusive and binding upon such holder and upon all future
         holders and owners of this Note and any Notes which may be issued
         in exchange or substitute hereof, irrespective of whether or not
         any notation thereof is made upon this Note or such other Notes.

              The indebtedness evidenced by the Notes is, to the extent and
         in the manner provided in the Indenture, expressly subordinate and
         subject in right of payment to the prior payment in full of all
         Senior Indebtedness of the Company, as defined in the Indenture,
         whether outstanding at the date of the Indenture or thereafter
         incurred, and this Note is issued subject to the provisions of the
         Indenture with respect to such subordination.  Each holder of this
         Note, by accepting the same, agrees to and shall be bound by such
         provisions and authorizes the Trustee on his behalf to take such
         action as may be necessary or appropriate to effectuate the
         subordination so provided and appoints the Trustee his attorney-
         in-fact for such purpose.

              No reference herein to the Indenture and no provision of this
         Note or of the Indenture shall alter or impair the obligation of
         the Company, which is absolute and unconditional, to pay the
         principal of and any premium and interest on this Note at the
         place, at the respective times, at the rate and in the coin or
         currency herein prescribed. 

              Interest on the Notes shall be computed on the basis of a
         360-day year comprised of twelve 30-day months.

              The Notes are issuable in registered form without coupons in
         denominations of $1,000 and any integral multiple of $1,000.  At
         the office or agency of the Company referred to on the face
         hereof, and in the manner and subject to the limitations provided
         in the Indenture, without payment of any service charge but with
         payment of a sum sufficient to cover any tax or other governmental
         charge that may be imposed in connection with any registration or
                                        B-2





         exchange of Notes, Notes may be exchanged for a like aggregate
         principal amount of Notes of other authorized denominations.

              The Notes will not be redeemable at the option of the Company
         prior to March 15, 1999.  At any time on or after March 15, 1999,
         and prior to maturity, the Notes may be redeemed at the option of
         the Company as a whole, or from time to time in part, upon mailing
         a notice of such redemption not less than 30 nor more than 60 days
         before the date fixed for redemption to the holders of Notes at
         their last registered addresses, all as provided in the Indenture,
         at the following optional redemption prices (expressed as
         percentages of the principal amount), together in each case with
         accrued interest to, but excluding, the date fixed for redemption.

              If redeemed during the 12-month period beginning March 15:


                        YEAR                          PERCENTAGE
                        -----                         -----------

                        1999.......................... 102.70%

                        2000.......................... 101.35%


         Provided that if the date fixed for redemption is on March 15 or
         September 15, then the interest payable on such date shall be paid
         to the holder of record on the next preceding March 1 or September
         1, respectively.

              The Notes are not subject to redemption through the operation
         of any sinking fund.  

              If a Repurchase Event (as defined in the Indenture) occurs
         prior to March 15, 2001, the holder of this Note shall have the
         right, in accordance with the provisions of the Indenture, to
         require the Company to repurchase this Note for cash at a
         Repurchase Price equal to 100% of the principal amount plus
         accrued and unpaid interest to, but excluding, the Repurchase
         Date; provided that if such Repurchase Date is March 15 or
         September 15, then the interest payable on such date shall be to
         the holder of record of the Note on the next preceding March 1 or
         September 1, respectively.  Within 30 days after the occurrence of
         a Repurchase Event, the Company is obligated to give all holders
         of record of Notes notice of the occurrence of such Repurchase
         Event and of the repurchase right arising as a result thereof.  

              Subject to the provisions of the Indenture, the holder hereof
         has the right, at its option, at any time after 60 days following
         the latest date of original issuance of the Notes and prior to the
                                        B-3





         close of business on March 15, 2001, or, as to all or any portion
         hereof called for redemption, prior to the close of business on
         the second Business Day immediately preceding the date fixed for
         redemption (unless the Company shall default in payment due upon
         redemption thereof), to convert the principal hereof or any
         portion of such principal which is $1,000 or an integral multiple
         thereof, into that number of shares of Company's Common Stock, as
         said shares shall be constituted at the date of conversion,
         obtained by dividing the principal amount of this Note or portion
         thereof to be converted by the Conversion Price of $19.75 or such
         Conversion Price as adjusted from time to time as provided in the
         Indenture, upon surrender of this Note, together with a conversion
         notice as provided in the Indenture, to the Company at the office
         or agency of the Company maintained for that purpose in the
         Borough of Manhattan, The City of New York, or at the option of
         such holder, the Corporate Trust Office, and, unless the shares
         issuable on conversion are to be issued in the same name as this
         Note, duly endorsed by, or accompanied by instruments of transfer
         in form satisfactory to the Company duly executed by, the holder
         or by his duly authorized attorney.  No adjustment in respect of
         interest or dividends will be made upon any conversion; provided,
         however, that if this Note shall be surrendered for conversion
         during the period from the close of business on any record date
         for the payment of interest to the close of business on the
         Business Day preceding the interest payment date, this Note
         (unless it or the portion being converted shall have been called
         for redemption during the period from the close of business on any
         record date for the payment of interest to the close of business
         on the second Business Day next succeeding the interest payment
         date) must be accompanied by an amount, in New York Clearing House
         funds or other funds acceptable to the Company, equal to the
         interest payable on such interest payment date on the principal
         amount being converted.  No fractional shares will be issued upon
         any conversion, but an adjustment in cash will be made, as
         provided in the Indenture, in respect of any fraction of a share
         which would otherwise be issuable upon the surrender of any Note
         or Notes for conversion.

              Any Notes called for redemption, unless surrendered for
         conversion on or before the close of business on the second
         Business Day next preceding date fixed for redemption, may be
         deemed to be purchased from the holder of such Notes at an amount
         equal to the applicable redemption price, together with accrued
         interest to, but excluding, the date fixed for redemption, by one
         or more investment bankers or other purchasers who may agree with
         the Company to purchase such Notes from the holders thereof and
         convert them into Common Stock of the Company and to make payment
         for such Notes as aforesaid to the Trustee in trust for such
         holders.

         authenticating agent nor any paying agent nor any other conversion
         agent nor any Note registrar shall be affected by any notice to

         registered holder shall, to the extent of the sum or sums paid,
         satisfy and discharge liability for monies payable on this Note.

              No recourse for the payment of the principal of or any
         premium or interest on this Note, or for any claim based hereon or
         otherwise in respect hereof, and no recourse under or upon any
         obligation, covenant or agreement of the Company in the Indenture
         or any indenture supplemental thereto or in any Note, or because
         of the creation of any indebtedness represented thereby, shall be
         had against any incorporator, stockholder, employee, agent,
         officer or director or subsidiary, as such, past, present or

         whether by virtue of any constitution, statute or rule of law or
         by the enforcement of any assessment or penalty or otherwise, all
         such liability being, by the acceptance hereof and as part of the
         consideration for the issue hereof, expressly waived and released.

             Terms used in this Note and defined in the Indenture are used
         herein as therein defined.
