any action under any provision of this Indenture, the Company shall, with
respect to any application or request to make an optional redemption or
Mandatory Conversion and, upon the request of the Trustee with respect to any

         complied with; and

                 (d)      a statement as to whether, in the opinion of each

         SECTION 1.05     Form of Documents Delivered to Trustee.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all

Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more





                                       16
   18
other such Persons as to other matters, and any such Person may certify or give
an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such officer's certificate or opinion is

insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the

         other action provided by this Indenture to be given or taken by
         Noteholders may be embodied in and evidenced by one or more
         instruments of substantially similar tenor signed by such Noteholders
         in person or by agents duly appointed in writing; and, except as
         herein otherwise expressly provided, such action shall become
         effective when such instrument or instruments are delivered to the
         Trustee and, where it is hereby expressly required, to the Company.
         Such instrument or instruments (and the action embodied therein and
         evidenced thereby) are herein sometimes referred to as the "Act" of
         the Noteholders signing such instrument or instruments.  Proof of
         execution of any such instrument or of a writing appointing any such
         agent shall be sufficient for any purpose of this Indenture and
         conclusive in favour of the Trustee and the Company, if made in the
         manner provided in this Section.

                 (b)      The fact and date of the execution by any Person of
         any such instrument or writing may be proved by the affidavit of a
         witness of such execution or by a certificate of a notary public or
         other officer authorized by law to take acknowledgments of deeds,
         certifying that the individual signing such instrument or writing
         acknowledged to such witness, notary public or other such officer the
         execution thereof.  Where such execution





                                       17
   19
         is by a signer acting in a capacity other than such signer's
         individual capacity, such certificate or affidavit shall also
         constitute sufficient proof of authority.  The fact and date of the
         execution of any such instrument or writing, or the authority of the
         Person executing the same, may also be proved in any other manner
         which the Trustee deems sufficient.

                 (c)      Any Extraordinary Resolution, request, demand,
         authorization, direction, notice, consent, waiver or other Act of the
         Holders of any Note shall bind every future Holder of the same Note
         and the Holder of every Note issued upon conversion or redemption
         thereof or in exchange therefor or in lieu thereof in respect of
         anything done, omitted or suffered to be done by the Trustee or the
         Company in reliance thereon, whether or not notation of such action is
         made upon such Note.

         SECTION 1.08     Notice to Noteholders; Waiver.

         Where this Indenture provides for notice of any event to Noteholders
by the Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if published in an Authorised Newspaper.
Neither the Trustee nor the Company need give any notice to the Couponholders

         In case by reason of any cause it shall be impracticable to publish
notice of any event to the Noteholders when such notice is required to be given
pursuant to any provision of this Indenture, then any manner of giving such
notice as shall be satisfactory to the Trustee shall constitute a sufficient
notification for every purpose hereunder.

         The principal of and interest on the Notes shall be payable at the

         SECTION 3.03     Execution, Authentication, Delivery and Dating.

         The Notes shall be executed on behalf of the Company by its Chairman,
a Vice Chairman, its President or a Vice President under a facsimile of its
corporate seal reproduced thereon and attested by its Secretary or an Assistant
Secretary.  The signature of any of these officers on the Notes may be manual
or facsimile signatures of the present or any future such authorized officer
and may be imprinted or otherwise reproduced on the Notes.

         Notes bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Notes or did not hold
such offices at the date of such Notes.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Notes executed by the Company to the
Trustee for authentication, together with a Company Order for the
authentication and delivery of such Notes, and the Trustee or the
Authenticating Agent in accordance with such Company Order shall authenticate
and deliver such Notes.  Such Company Order shall specify the amount of Notes
to be authenticated and the date





                                       23
   25
on which the original issue of Notes is to be authenticated.  The aggregate
principal amount of Notes outstanding at any time may not exceed $40,000,000

         Each Note shall be dated as of July 30, 1996.

         No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for in Exhibit
A duly executed by the Trustee or the Authenticating Agent by manual or
facsimile signature of an authorized officer, and such certificate upon any
Note shall be conclusive evidence, and the only evidence, that such Note has
been duly authenticated and delivered hereunder and is entitled to the benefits
of this Indenture.

         In case the Company, pursuant to Article Eight, shall be consolidated
or merged with or into any other Person or shall convey, transfer, lease or
otherwise dispose of its properties and assets substantially as an entirety to
any Person, and the successor Person resulting from such consolidation, or
surviving such merger, or into which the Company shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Eight, any of the Notes authenticated or
delivered prior to such consolidation, merger, conveyance, transfer, lease or
other disposition may, from time to time, at the request of the successor
Person, be exchanged for other Notes executed in the name of the successor
Person with such changes in phraseology and form as may be appropriate, but
otherwise in substance of like tenor as the Notes surrendered for such exchange
and of like principal amount; and the Trustee or an Authenticating Agent, upon
Company Request of the successor Person, shall authenticate and deliver Notes
as specified in such request for the purpose of such exchange.

         SECTION 3.04     Temporary Notes.

         Pending the preparation of definitive Notes, but in no event prior to
September 9, 1996, the Company may execute, and upon Company Order the Trustee
or an Authenticating Agent shall authenticate and deliver, temporary Notes
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Notes in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Notes may determine, as conclusively evidenced by their
execution of such Notes.

         If temporary Notes are issued, the Company will cause definitive Notes
to be prepared without unreasonable delay, but in no event prior to September
9, 1996.  After the preparation of





                                       24
   26
definitive Notes, the temporary Notes shall be exchangeable for definitive
Notes upon surrender of the temporary Notes at the office or agency of the
Company designated for such purpose pursuant to Section 10.02, without charge
to the Noteholder.  Upon surrender for cancellation of any one or more
temporary Notes, the Company shall execute and the Trustee or an Authenticating
Agent shall authenticate and deliver in exchange therefor a like principal
amount of definitive Notes of authorized denominations.  Until so exchanged,
the temporary Notes shall in all respects be entitled to the same benefits
under this Indenture as definitive Notes.

         SECTION 3.05     Exchange.

         Upon surrender for exchange of any Note at the office or agency of the
Company designated pursuant to Section 10.02, the Company shall execute, and
the Trustee or the Authenticating Agent shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Notes of any
authorized denomination or denominations of a like aggregate principal amount.

         Furthermore, any Holder of the Global Note shall, by acceptance of
such Global Note, agree that transfers of beneficial interest in such Global
Note may be effected only through a book-entry system maintained by the Holder
of such Global Note (or its agent), and that ownership of a beneficial interest
in the Global Note shall be required to be reflected in a book entry.

         At the option of the Noteholder, Notes may be exchanged for other
Notes of the Authorized Denomination and of a like aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency.  Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee or an Authenticating Agent shall authenticate and deliver, the Notes
which the Noteholder making the exchange is entitled to receive.

         All Notes issued upon any exchange of Notes shall be the valid
obligations of the Company, evidencing the same debt, and entitled to the same
benefits under this Indenture, as the Notes surrendered upon such exchange.

         Every Note presented or surrendered for exchange shall (if so required
by the Company or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer, in form satisfactory to the Company and the Trustee,
duly executed by the Noteholder thereof or such Noteholder's attorney duly
authorized in writing.

         No service charge shall be made for any exchange, conversion or
redemption of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental





                                       25
   27
charge that may be imposed in connection with any exchange of Notes, other than
exchanges pursuant to Sections 3.03, 3.04, 3.05, 3.06, 9.05, or 11.08.

         The Company shall not be required (i) to issue or exchange any Note
during a period beginning at the opening of business 15 days before the
selection of Notes to be redeemed under Section 11.04 and ending at the close
of business on the day of such mailing of the relevant notice of redemption,
(ii) to exchange any Note so selected for redemption in whole or in part,
except the unredeemed portion of any Note being redeemed in part or (iii) to
register the transfer of or exchange of any Note during a period beginning five
days before the date of Maturity and ending on such date of Maturity.

         SECTION 3.06     Book-Entry Provisions for Global Note.

                 (a)      The Global Note initially shall be delivered to the
         Common Depository and shall bear the legends set forth in Section
         2.02. Members of, or participants in, Euroclear and Cedel ("Agent
         Members") shall have no rights under this Indenture with respect to
         any Global Note held on their behalf by the Common Depository, or
         under the Global Note, and the Common Depository may be treated by the
         Company, the Trustee and any agent of the Company or the Trustee as
         the absolute owner of such Global Note for all purposes whatsoever.
         Notwithstanding the foregoing, nothing herein shall prevent the
         Company, the Trustee or any agent of the Company or the Trustee, from
         giving effect to any written certification, proxy or other
         authorization furnished by the Common Depository or shall impair, as
         between the Common Depository and the Agent Members, the operation of
         customary practices governing the exercise of the rights of a
         Noteholder.

                 (b)      Transfers of the Global Note shall be limited to
         transfers of such Global Note in whole, but not in part, to the Common
         Depository, its successors or their respective nominees.  Interests of
         beneficial owners in the Global Note may be transferred in accordance
         with the rules and procedures of the Common Depository and the
         provisions of Section 3.06.  Beneficial owners may obtain Bearer Notes
         in exchange for their beneficial interests in the Global Note upon
         request in accordance with the Common Depository's procedures.  In
         addition, Bearer Notes shall be transferred to all beneficial owners
         in exchange for their beneficial interests in the Global Note if (i)
         the Common Depository notifies the Company that it is unwilling or
         unable to continue as Common Depository for the Global Note and a
         successor depository is not appointed by the Company within 90 days of
         such notice or (ii) an Event of Default has occurred and is continuing
         and the Trustee has received a request from the Common Depository.

                 (c)      In connection with any transfer of a portion of the
         beneficial interest in the Global Note to beneficial owners pursuant
         to subsection (b) of this Section, the Common Depository shall reflect
         on its books and records the date and a decrease in the principal
         amount of the Global Note in an amount equal to the principal amount
         of the beneficial interest in the Global Note to be transferred, and
         the Company shall execute, and the Trustee or an Authenticating Agent
         shall authenticate and deliver, one or more Bearer Notes of like tenor
         and amount.

                 (d)      In connection with the transfer of the entire Global
         Note to beneficial owners pursuant to subsection (b) of this Section,
         the Global Note shall be deemed to be surrendered to the Trustee for
         cancellation, and the Company shall execute, and the Trustee or an
         Authenticating Agent shall authenticate and deliver, to each
         beneficial owner identified by the Common Depository in exchange for
         its beneficial interest in the Global Note, an equal aggregate
         principal amount of Bearer Notes of authorized denominations.

                 (e)      Any Bearer Note delivered in exchange for an interest
         in the Global Note pursuant to subsection (b) or subsection (c) of
         this Section shall bear the applicable legend regarding transfer
         restrictions applicable to the Bearer Note set forth in Section 2.02.

                 (f)      The Holder of the Global Note may grant proxies and
         otherwise authorize any person, including Agent Members and persons
         that may hold interests through Agent Members, to take any action
         which a Noteholder is entitled to take under this Indenture or the
         Notes.

                 (g)      Any Bearer Note delivered in exchange for an interest
         in the Global Note pursuant to subsection (b) or (c) of this Section
         will prior to delivery to the Noteholder have all matured Coupons as
         of such delivery date, which are attached to such Bearer Note,
         cancelled and voided by the Authenticating Agent.

                 (h)      Nothing contained herein shall be deemed to authorize
         any transfers (by book-entry or otherwise) of the Global Note prior to
         September 9, 1996, it being understood that no transfers of the Global
         Note or any beneficial interest may occur until after September 9,
         1996.

         SECTION 3.07     Special Transfer Provisions.

         The Noteholders by acceptance of the Notes hereby covenant and agree
that neither the Notes nor the Conversion Shares will be offered, sold,
transferred, pledged, converted or otherwise disposed of in the United States
or to, or for the account or benefit of, any U.S. Person





                                       27
   29
unless the Notes and the Conversion Shares have been registered under the
Securities Act and any applicable state securities or blue sky laws or
exemptions from the registration requirements of such laws are available.

         SECTION 3.08     Mutilated, Destroyed, Lost and Stolen Notes.

         If (i) any mutilated Note or Coupon is surrendered to the Trustee or
the Authenticating Agent, or (ii) the Company and the Trustee receive evidence
to their satisfaction of the destruction, loss or theft of any Note or Coupon,
and there is delivered to the Company and the Trustee such security and/or
indemnity as may be required by them to save each of them harmless, then, in
the absence of notice to the Company or the Trustee that such Note or Coupon
has been acquired by a bona fide purchaser, the Company shall execute and upon
Company Order the Trustee or an Authenticating Agent shall authenticate and
deliver, in exchange for any such mutilated Note or Coupon or in lieu of any
such destroyed, lost or stolen Note or Coupon, a new Note or Coupon of like
tenor and principal amount, bearing a number not contemporaneously Outstanding.

         In case any such mutilated, destroyed, lost or stolen Note or Coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Note or Coupon, pay such Note or Coupon, as the
case may be.

         Upon the issuance of any new Note or Coupon under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee and the Authenticating
Agent) connected therewith.

         Every new Note or Coupon issued pursuant to this Section in lieu of
any destroyed, lost or stolen Note or Coupon shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Note or Coupon shall be at any time enforceable by anyone, and
shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Notes or Coupons duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Note or Coupon.

         Any new Note issued under this Section 3.08 in lieu of any destroyed,
lost or stolen Note shall be issued by the Authenticating Agent with all
matured Coupons as of such date of issuance cancelled or voided.

         SECTION 3.09     Payment of Interest; Interest Rights Preserved.

         Interest on any Note which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date, shall be paid to the bearer against
presentation and surrender (or in the case of part payment only, endorsement)
of the relevant Coupons, outside of the United States at the corporate trust
office or agency of any Paying Agent maintained for such purpose pursuant to
Section 10.02.

         Each such payment will be made at the specified office of any Paying
Agent, at the option of the Holder of such Coupon, by U.S. dollar cheque drawn
on, or by transfer to a U.S. dollar account maintained by the payee with a bank
in Europe subject in all cases to any applicable fiscal or other laws and
regulations.

         Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture in exchange for or in lieu of any other Note
shall carry the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Note.

         SECTION 3.10     Persons Deemed Owners.

         Subject to the provision of Section 3.14 and except with respect to
any unmatured Coupon, the Company, the Trustee and any agent of the Company or
the Trustee may treat the Person who is the bearer of any Note or Coupon as the
owner of such Note or Coupon for the purpose of receiving payment of principal
of and (subject to Sections 3.05 and 3.09) interest on such Note and for all
other purposes whatsoever, whether or not such Note be overdue, and none of the
Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         SECTION 3.11     Cancellation.

         All Notes surrendered for payment, conversion, redemption or exchange
shall, if surrendered to any Person other than the Trustee, be delivered to the
Trustee and shall be promptly cancelled by it.  The Company may at any time
deliver to the Trustee for cancellation any Notes previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Notes previously authenticated hereunder
which the Company has not issued and sold, and all Notes so delivered shall be
promptly cancelled by the Trustee.  If the Company shall so acquire any of the
Notes, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Notes unless and until the
same are surrendered to the Paying and Conversion Agent for cancellation.  No
Notes





                                       29
   31
shall be authenticated in lieu of or in exchange for any Notes cancelled as
provided in this Section, except as expressly permitted by this Indenture.  All
cancelled Notes held by the Paying and Conversion Agent shall be disposed of by
the Paying and Conversion Agent in accordance with its customary procedures and
certification of their disposal delivered to the Company unless by Company
Order the Company shall direct that cancelled Notes be returned to it.

         SECTION 3.12     Computation of Interest.

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

         SECTION 3.13     ISIN, CUSIP Or Other Identifying Numbers.

         The Company in issuing the Notes may use "ISIN", "CUSIP" or other
identifying numbers (if then generally in use), and the Trustee shall use ISIN,
CUSIP or other identifying numbers in notices of redemption, conversion or
exchange, and any other notice provided for the benefit of the Noteholders, as
a convenience to Noteholders; provided that any such notice shall state that no
representation is made as to the correctness of such numbers either as printed
on the Notes or as contained in any notice of redemption, conversion or
exchange or other notice.

         SECTION 3.14     Prescription.

         Notes and Coupons will become void unless presented for payment within
periods of ten (10) years (in the case of principal) and five (5) years (in the
case of interest) from the Relevant Date in respect of the Notes or the
Coupons, as the case may be, subject to the provisions of Section 11.09.

         10.03) have been delivered to the Trustee for cancellation; or

                 (b)      the Company has paid or caused to be paid all other

         Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 4.01 shall be held in
trust and applied by it, in accordance with the provisions of the Notes and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and interest for
whose payment such money has been deposited with the Trustee; but such money
need not be segregated from other funds except to the extent required by law.


                                  ARTICLE FIVE

                         EVENTS OF DEFAULT AND REMEDIES

         SECTION 5.01     Events of Default.

         "Event of Default," wherever used herein, means any one of the
following events (whatever the reason for such Event of Default and whether it
shall be occasioned by the provisions of Article Fourteen or 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) which shall have occurred and is
continuing:

                 (a)      if default is made for a period of five Business Days
         or more in the payment of interest or principal due in respect of the
         Notes or any of them; or

                 (b)      if the Company fails to perform or observe any of its
         other obligations, covenants, conditions or provisions under the Notes
         or this Indenture and (except where the Trustee shall have certified
         to the Company that it considers such failure to be incapable of
         remedy in which case no such notice or continuation as is hereinafter





                                       32
   34
         mentioned will be required) such failure continues for the period of
         30 calendar days (or such longer period as the Trustee may in its
         absolute discretion permit) next following the service by the Trustee
         on the Company of notice requiring the same to be remedied; or

                 (c)      if (i) any other Indebtedness of the Company or any
         Principal Subsidiary becomes due and payable prior to its Stated
         Maturity by reason of an event of default (howsoever defined) or (ii)
         any such Indebtedness of the Company or any Principal Subsidiary is
         not paid when due or, as the case may be, within any applicable grace
         period or (iii) the Company or any Principal Subsidiary fails to pay
         when due (or, as the case may be, within any applicable grace period)
         any amount payable by it under any present or future guarantee for, or
         indemnity in respect of, any Indebtedness of any Person or (iv) any
         security given by the Company or any Principal Subsidiary for any
         Indebtedness of any Person or any guarantee or indemnity of
         Indebtedness of any Person by the Company or any Principal Subsidiary
         becomes enforceable by reason of default in relation thereto and steps
         are taken to enforce such security save in any such case where there
         is a bona fide dispute as to whether the relevant Indebtedness or any
         such guarantee or indemnity as aforesaid shall be due and payable
         (following any applicable grace period), provided that in each such
         case the Indebtedness exceeds in the aggregate U.S.$1,000,000 and in
         each such case such event continues unremedied for a period of 30
         calendar days (or such longer period as the Trustee may in its sole
         discretion consent to in writing upon receipt of written notice from
         the Company); or

                 (d)      if the Company or any Principal Subsidiary shall
         generally fail to pay its debts as such debts come due (except debts
         which the Company or such Principal Subsidiary, as the case may be,
         may contest in good faith generally) or shall be declared or
         adjudicated by a competent court to be insolvent or bankrupt, shall
         consent to the entry of an order of relief against it in an
         involuntary bankruptcy case, shall enter into any assignment or other
         similar arrangement for the benefit of its creditors or shall consent
         to the appointment of a custodian (including, without limitation, a
         receiver, liquidator or trustee); or

                 (e)      if a receiver, administrative receiver, administrator
         or other similar official shall be appointed in relation to the
         Company or any Principal Subsidiary or in relation to the whole or a
         substantial part of the undertaking or assets of any of them or a
         distress, execution or other process shall be levied or enforced upon
         or sued out against, or an encumbrancer shall take possession of, the
         whole or a substantial part of the assets of any of them and  in any
         of the foregoing cases is not paid out or discharged within 90
         calendar days (or such longer period as the Trustee may in its
         absolute discretion consent to in writing upon receipt of written
         notice from the Company); or





                                       33
   35
                 (f)      if the Company or any Principal Subsidiary institutes
         proceedings to be adjudicated a voluntary bankrupt, or shall consent
         to the filing of a bankruptcy proceeding against it, or shall file a
         petition or answer or consent seeking organization under the laws of
         the Federal Bankruptcy Code or any similar applicable U.S. federal or
         state law, or shall consent to the filing of any such petition, or
         shall consent to the appointment of a receiver or liquidator or
         trustee or assignee (or other similar official) in bankruptcy or
         insolvency of it or its property, or shall make an assignment for the
         benefit of creditors, or shall admit in writing its inability to pay
         its debts generally as they come due; or

                 (g)      if a decree or order by a court having jurisdiction
         in the premises shall have been entered adjudging the Company or any
         Principal Subsidiary a bankrupt or insolvent, or approving as properly
         filed a petition seeking the reorganisation of the Company or any
         Principal Subsidiary under the Federal Bankruptcy Code or any other
         similar applicable U.S. federal or state law, and such decree or order
         shall have continued undischarged or unstayed for a period of 90
         calendar days; or a decree or order of a court having jurisdiction in
         the premises for the appointment of a receiver or liquidator or
         trustee or assignee (or other similar official) in bankruptcy or
         insolvency of the Company or any Principal Subsidiary or of all or
         substantially all of its property, or for the winding up or
         liquidation of its affairs, shall have been entered, and such decree
         or order shall have continued undischarged and unstayed for a period
         of 90 calendar days; or

                 (h)      if a warranty, representation, or other statement
         made by or on behalf of the Company contained in this Indenture, the
         Notes or any certificate or other agreement furnished in compliance
         with such documents is false in any material respect when made and
         (except where the Trustee shall have certified to the Company that it
         considers such falsity to be incapable of remedy, in which case no
         such notice or continuation as is hereinafter mentioned will be
         required) such falsity continues for a period of 30 calendar days (or
         such longer period as the Trustee may in its absolute discretion
         permit) next following the service by the Trustee on the Company of
         notice requiring the same to be remedied; or

                 (i)      if there is any final judgment or judgments for the
         payment of money exceeding in the aggregate U.S.$1,000,000 outstanding
         against the Company or any Principal Subsidiary which has been
         outstanding for more than 60 calendar days from the date of its entry
         and shall not have otherwise been discharged in full or stayed by
         appeal, bond or otherwise.

   36
         SECTION 5.02     Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 5.01(f) or 5.01(g)) occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Notes may, and the Trustee upon the request of the Holders of not
less than 25% in principal amount of the Outstanding Notes shall, declare the
principal amount of all the Notes to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Noteholders),
and upon any such declaration such principal amount shall become immediately
due and payable.

         If an Event of Default specified in Section 5.01(f) or 5.01(g) occurs
and is continuing, then the principal amount of all the Notes shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Noteholder.

         At any time after a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a majority
in principal amount of the Outstanding Notes, by written notice to the Company
and the Trustee, may rescind and annul such declaration and its consequences if

                 (a)      the Company has paid or deposited with the Trustee a
         sum sufficient to pay

                          (i)     all overdue interest on all Outstanding
                 Notes,

                          (ii)    all unpaid principal of any Outstanding Notes
                 which has become due otherwise than by such declaration of
                 acceleration, and interest on such unpaid principal at the
                 rate prescribed therefor in the Notes,

                          (iii)   to the extent that payment of such interest
                 is legally enforceable, interest on overdue interest at the
                 rate prescribed therefor in the Notes, and

                          (iv)    all sums paid or advanced by the Trustee
                 hereunder and the reasonable compensation, expenses,
                 disbursements and advances of the Trustee, its agents and
                 counsel; and

                 (b)      all Events of Default, other than the non-payment of
         amounts of principal of or interest on Notes which have become due
         solely by such declaration of acceleration, have been cured or waived
         as provided in Section 5.13.





                                       35
   37
         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         SECTION 5.03     Collection of Indebtedness and Suits for Enforcement
                          by Trustee.

         The Company covenants that if

                 (a)      default is made in the payment of any instalment of
         interest on any Note when such interest becomes due and payable and
         such default continues for a period of five Business Days, or

                 (b)      default is made in the payment of the principal of
         any Note at the Maturity thereof and such default continues for a
         period of five Business Days,

the Company will, upon demand of the Trustee, pay to the Trustee for the
benefit of the Holders of such Notes, the whole amount then due and payable on
such Notes for principal and interest, and interest on any overdue principal
and, to the extent that payment of such interest shall be legally enforceable,
upon any overdue instalment of interest, at the rate prescribed therefor in the
Notes, and, in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Notes and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or any other obligor upon the Notes, wherever situated.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Noteholders by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

         SECTION 5.04     Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the Notes
or the property of the





                                       36
   38
Company or of such other obligor or their creditors, 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 on the Company for the payment of overdue
principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

                 (a)      to file and prove a claim for the whole amount of
         principal and interest owing and unpaid in respect of the Notes and to
         file such other papers or documents as may be necessary or advisable
         in order to have the claims of the Trustee (including any claim for
         the reasonable compensation, expenses, disbursements and advances of
         the Trustee, its agents and counsel) and of the Noteholders allowed in
         such judicial proceeding, and

                 (b)      to collect and receive any moneys or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Noteholder 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 the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 6.06.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Noteholder any plan
of reorganization, arrangement, adjustment or composition affecting the Notes
or the rights of any Noteholder thereof, or to authorize the Trustee to vote in
respect of the claim of any Noteholder in any such proceeding.

         SECTION 5.05     Trustee May Enforce Claims Without Possession of
                          Notes.

         All rights of action and claims under this Indenture or the Notes may
be prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any
such 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 Noteholders in respect of which such judgment has been
recovered.





                                       37
   39

         SECTION 5.06     Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or interest,
upon presentation of the Notes and the notation thereon of 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 6.06;

                 SECOND:  To the payment of the amounts then due and unpaid for
         principal of and interest on the Notes in respect of which or for the
         benefit of which such money has been collected, ratably, without
         preference or priority of any kind, according to the amounts due and
         payable on such Notes for principal and interest, respectively; and

                 THIRD:  The balance, if any, to the Person or Persons entitled
         thereto.

         SECTION 5.07     Limitation on Suits.

         No Noteholder shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment
of a receiver or trustee, or for any other remedy hereunder, unless

                 (a)      such Noteholder has previously given written notice
         to the Trustee of a continuing Event of Default, with a copy of such
         notice to the Company;

                 (b)      the Holders of not less than 25% in principal amount
         of the Outstanding Notes shall have made written request to the
         Trustee to institute proceedings in respect of such Event of Default
         in its own name as Trustee hereunder;

                 (c)      such Noteholder or Noteholders have offered to the
         Trustee reasonable indemnity against the costs, expenses and
         liabilities to be incurred in compliance with such request;

                 (d)      the Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity has failed to institute any
         such proceeding; and

                 (e)      no direction inconsistent with such written request
         has been given to the Trustee during such 60-day period by the Holders
         of a majority or more in principal amount of the Outstanding Notes;





                                       38
   40
         it being understood and intended that no one or more Noteholders 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 Noteholders, or to obtain or to seek to obtain
         priority or preference over any other Noteholders or to enforce any
         right under this Indenture, except in the manner herein provided and
         for the equal and ratable benefit of all the Noteholders.

         SECTION 5.08     Unconditional Right of Holders to Receive Principal
                          and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Note or of any Coupon, as the case may be, shall have the right, which is
absolute and unconditional, to receive payment, as provided herein (including,
if applicable, Article Thirteen) and in such Note of the principal of and
(subject to Section 3.09) interest on, such Note on the respective Stated
Maturity or expressed in such Note (or, in the case of redemption, on the
Redemption Date) or Coupon and to institute suit for the enforcement of any
such payment, and such rights shall not be impaired without the consent of such
Holder; provided, that all monies paid by the Company to the Paying Agent for
the payment of principal or interest on any Note which remain unclaimed at the
end of two (2) years after the Stated Maturity or Redemption Date of such Note
will be repaid to the Company and the Holder of any Note or Coupon shall
thereafter have only the rights of a creditor of the Company or such rights as
may be otherwise provided by applicable law.

         SECTION 5.09     Restoration of Rights and Remedies.

         If the Trustee or any Noteholder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Noteholder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Noteholders
shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the
Noteholders shall continue as though no such proceeding had been instituted.

         SECTION 5.10     Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of
Section 3.08, no right or remedy herein conferred upon or reserved to the
Trustee or to the Noteholders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy





                                       39
   41
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

         SECTION 5.11     Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Note to
exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to the Noteholders may be exercised from time to time,
and as often as may be deemed expedient, by the Trustee or by the Noteholders,
as the case may be.

         SECTION 5.12     Control by Noteholders.

         The Holders of not less than a majority in aggregate principal amount
of the Outstanding Notes 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 that in each
case

                 (a)      such direction shall not be in conflict with any rule
         of law or with this Indenture,

                 (b)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such direction, and

                 (c)      the Trustee need not take any action which might
         involve it in personal liability or be unjustly prejudicial to the
         Noteholders not joining in such direction.

         SECTION 5.13     Waiver of Past Defaults.

         Subject to Section 5.02, the Holders of not less than a majority in
principal amount of the Outstanding Notes may on behalf of the Holders of all
the Notes waive any past default hereunder and its consequences, except a
default

                 (a)      in respect of the payment of the principal of or
         interest on any Note, or

                 (b)      in respect of a covenant or provision hereof which
         under Article Nine cannot be modified or amended without the consent
         of the Holder of each Outstanding Note affected.





                                       40
   42
         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

         SECTION 5.14     Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any
such law and covenants that it will not 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 had been enacted.

         SECTION 5.15     Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Note by
such Noteholder's 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, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and 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; but the provisions of this Section shall not be deemed to require any
court to require an undertaking or to make such an assessment in any suit
instituted by the Company except against the Trustee.


                                  ARTICLE SIX

                                  THE TRUSTEE

         SECTION 6.01     Notice of Defaults.

         Within 90 days after the occurrence of any Default hereunder, the
Trustee shall publish notice of such Default hereunder known to the Trustee,
unless such Default shall have been cured or waived; provided, however, that,
except in the case of a Default in the payment of the principal





                                       41
   43
of or interest on any Note, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interest of the
Noteholders.

         SECTION 6.02     Certain Rights of Trustee.

                 (a)      The Trustee may request and rely and shall be
         protected in acting or refraining from acting upon any Extraordinary
         Resolution, Act, Notice or other resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties.

                 (b)      Any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Company Request or Company
         Order and any resolution of the Board of Directors may be sufficiently
         evidenced by a Board Resolution.

                 (c)      Whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate.

                 (d)      The Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon.

                 (e)      The Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Indenture at the
         request or direction of any of the Noteholders pursuant to this
         Indenture, unless such Noteholders shall have offered to the Trustee
         reasonable security or indemnity against the costs, expenses
         (including reasonable fees of Trustee's counsel), and liabilities
         which might be incurred by it in compliance with such request or
         direction.

                 (f)      The Trustee shall not be bound to make any
         investigation into the facts or matters stated in any Extraordinary
         Resolution, Act, Notice or other resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document, but the





                                       42
   44
         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.

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

                 (h)      The Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture.

                 (i)      The permissive right of the Trustee to take or
         refrain from taking any actions enumerated in this Indenture shall not
         be confused as a duty and the Trustee shall not be answerable in such
         actions other than for its own negligence or wilful misconduct.

         The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

         SECTION 6.03     Trustee Not Responsible for Recitals or Issuance of
                          Notes.

         The recitals contained herein in the Notes, except for the Trustee's
certificates of authentication, and in the Coupons, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their
correctness.  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes or the Coupons or of the
Conversion Shares, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Notes and
perform its obligations hereunder.  The Trustee shall not be accountable for
the use or application by the Company of Notes or the proceeds thereof.

         SECTION 6.04     May Hold Notes.

         The Trustee, any Paying Agent, any Conversion Agent or any other agent
of the Company or of the Trustee, in its individual or any other capacity, may
become the owner or pledgee of Notes and the Coupons and may otherwise deal
with the Company with the same rights it would have if it were not Trustee,
Paying Agent, Conversion Agent or such other agent.





                                       43
   45
         SECTION 6.05     Money Held in Trust.

         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
otherwise agreed with the Company.

         SECTION 6.06     Compensation and Reimbursement.

         The Company agrees:

                 (a)      to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                 (b)      except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence, bad faith or wilful
         misconduct; and

                 (c)      to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the
         acceptance or administration of this trust, including the costs and
         expenses of defending itself against any claim or liability in
         connection with the exercise or performance of any of its powers or
         duties hereunder.

         When the Trustee incurs expenses or renders service in connection with
an Event of Default specified in Section 5.01 (f) or Section 5.01 (g), the
expenses (including the reasonable charges of its counsel) and the compensation
for the services are intended to constitute expenses of the administration
under any applicable federal or state bankruptcy, insolvency or other similar
law.

         As security for the performance of the obligations of the Company
under this Section, the Trustee shall have a claim prior to the Notes upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of or interest on particular Notes.





                                       44
   46
         The provision of this Section shall survive the termination of this
Indenture or the earlier resignation or removal of the Trustee.  Any Paying
Agent or Authenticating Agent appointed hereunder shall be entitled to the
benefits of Section 6.06 (c) as if the indemnity set forth therefor were
specifically afforded to such Paying Agent or Authenticating Agent.

         SECTION 6.07     Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee and shall have a combined capital and surplus of at
least $50,000,000.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of federal, state, territorial
or District of Columbia supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time 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 6.08     Resignation and Removal; Appointment of Successor.

                 (a)      No resignation or removal of the Trustee and no
         appointment of a successor Trustee pursuant to this Article shall
         become effective until the acceptance of appointment by the successor
         Trustee in accordance with the applicable requirements of Section
         6.09.

                 (b)      The Trustee may resign at any time by giving written
         notice thereof to the Company.  If the instrument of acceptance by a
         successor Trustee required by Section 6.09 shall not have been
         delivered to the Trustee within 30 days after the giving of such
         notice of resignation, the resigning Trustee may petition any court of
         competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Act of the
         Holders of not less than a majority in principal amount of the
         Outstanding Notes, delivered to the Trustee and to the Company.

                 (d)      If at any time:

                          (i)     the Trustee shall cease to be eligible under
                 Section 6.07 and shall fail to resign after written request
                 therefor by the Company or by any Noteholder who has been a
                 bona fide Holder of a Note for at least six months, or





                                       45
   47
                          (ii)    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, or

                          (iii)   the Trustee shall fail or refuse to timely
                 carry out and discharge its duties hereunder,

         then, in any such case, (i) the Company, by a Board Resolution, may
         remove the Trustee, or (ii) any Noteholder who has been a bona fide
         Holder of a Note for at least six months may, on behalf of such
         Noteholder and all others similarly situated, petition any court of
         competent jurisdiction for the removal of the Trustee and the
         appointment of a successor Trustee.

                 (e)      If the Trustee shall resign, be removed or become
         incapable of acting, or if a vacancy shall occur in the office of
         Trustee for any reason, the Company, by a Board Resolution, shall
         promptly appoint a successor Trustee.  If, within one year after such
         resignation, removal or incapability, or the occurrence of such
         vacancy, a successor Trustee shall be appointed by Act of the Holders
         of a majority in principal amount of the Outstanding Notes delivered
         to the Company and the retiring Trustee, the successor Trustee so
         appointed shall, forthwith upon its acceptance of such appointment,
         become the successor Trustee and supersede the successor Trustee
         appointed by the Company.  If no successor Trustee shall have been so
         appointed by the Company or the Noteholders and accepted appointment
         in the manner hereinafter provided, any Noteholder who has been a bona
         fide Holder of a Note for at least six months may, on behalf of such
         Noteholder and all others similarly situated, petition any court of
         competent jurisdiction for the appointment of a successor Trustee.

                 (f)      The Company shall give notice of each resignation and
         each removal of the Trustee and each appointment of a successor
         Trustee to the Noteholders in the manner provided for in Section 1.08.
         Each notice shall include the name of the successor Trustee and the
         address of its Corporate Trust Office.

         SECTION 6.09     Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights,





                                       46
   48
powers, trusts and duties of the retiring Trustee; but, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, including any funds held in the
Segregated Account, whether or not invested.  Upon request of any such
successor Trustee, the Company shall execute any and all instruments for more
fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts.

         No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

         SECTION 6.10     Merger, Conversion, Consolidation or Succession to
                          Business.

         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, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Notes shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Notes so authenticated with the same effect
as if such successor Trustee had itself authenticated such Notes; and in case
at that time any of the Notes shall not have been authenticated, any successor
Trustee may authenticate such Notes either in the name of any predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the 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 to authenticate Notes in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion
or consolidation.

         SECTION 6.11     Certain Duties and Responsibilities.

                 (a)      Except during the continuance of an Event of Default
         with respect to the Notes,

                          (i)     the Trustee undertakes to perform such duties
                 and only such duties with respect to the Notes as are
                 specifically set forth in this Indenture, and no





                                       47
   49
                 implied covenants or obligations with respect to the Notes
                 shall be read into this Indenture against the Trustee; and

                          (ii)    in the absence of bad faith on its part, the
                 Trustee may conclusively rely as to the truth of the
                 statements and the correctness of the opinions expressed
                 therein, upon 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 provision hereof are specifically required to be furnished
                 to the Trustee, the Trustee shall be under a duty to examine
                 the same to determine whether or not they conform to the
                 requirements of this Indenture, but not to verify the contents
                 thereof.

                 (b)      In case an Event of Default has occurred and is
         continuing of which a Responsible Officer of the Trustee has actual
         knowledge, the Trustee shall exercise such of the rights and powers
         vested in it by this Indenture with respect to the Notes, and use the
         same degree of care and skill in their exercise, as a prudent person
         would exercise or use under the circumstances in the conduct of such
         person's own affairs.

                 (c)      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 wilful misconduct, except
         that

                          (i)     this Subsection shall not be construed to
                 limit the effect of Subsection (a) of this Section;

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

                          (iii)   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 Noteholders, given as
                 provided in Section 5.12, 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

                          (iv)    no provision of this Indenture shall require
                 the Trustee to expend or risk its own funds or otherwise incur
                 any financial liability in the performance of any of its
                 duties hereunder, or in the exercise of any of its rights or
                 powers, if it





                                       48
   50
                 shall have reasonable grounds for believing that repayment of
                 such funds or adequate indemnity against such risk or
                 liability is not reasonably assured to it.

                 (d)      Whether or not therein expressly so 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.

         SECTION 6.12     Segregated Account.

                 (a)      On the Closing Date or the day immediately following
         the Closing Date the net proceeds received from the sale of the Notes
         shall be transferred to the Segregated Account to be held until such
         time as such proceeds may be distributed to the Company in accordance
         with this Section or used by the Company in accordance with the
         provisions of Article Four and Article Thirteen hereof.

                 (b)      On the Closing Date or the date immediately following
         the Closing Date, the Company will establish the Segregated Account
         with Trustee on behalf of the Company.  The Trustee shall have a duty
         to invest the funds held in the Segregated Account from time to time
         in accordance with any Company Request received by the Trustee from
         the Company from time to time.  Funds held by the Trustee will be
         invested and reinvested in Permitted Investments as directed in
         writing by the Company.  Interest earned on investments made with the
         funds in the Segregated Account from time to time and on deposit in
         the Segregated Account will be held for the account of the Company and
         also invested in accordance with the instructions provided by the
         Company from time to time in a Company Order in Permitted Investments.
         The Trustee will distribute such earnings to the Company upon written
         request.

                 (c)      Upon conversion of any Note, whether represented by
         an interest in the Global Note or a Bearer Note, into Conversion
         Shares pursuant to Article Twelve, from time to time, the Company may
         request that the Trustee make a distribution to the Company of funds
         held in the Segregated Account in an amount equal to the principal
         amount of such Note.  The balance of the principal amount for such
         Note remaining on deposit in the Segregated Account at the Conversion
         Date shall be distributed to the Company without regard to the then
         current Asset Value Coverage Ratio; provided, however, that no such
         distribution shall be made if an Event of Default shall have occurred
         and be continuing.  In addition, the Company may from time to time
         request that the Trustee distribute to the Company any other funds
         held in the Segregated Account.  The Trustee shall distribute to the
         Company such funds held in the Segregated Account to the





                                       49
   51
         extent that the Company on the date of such request provides the
         documents specified in Section 6.12(d) to the Trustee.

                 (d)      Upon making any written request to the Trustee for a
         distribution of a portion of the funds, including any earnings
         thereon, held in the Segregated Account, the Company will present to
         the Trustee a certificate from the chief financial officer of the
         Company including items (a) through (d) of Section 1.04 and in the
         form set forth as Exhibit D stating that (i) the required Asset Value
         Coverage Ratio has (A) been met in accordance with Section 10.13 as of
         the date of such request and (B) will be met, following distribution
         of such funds from the Segregated Account (which certification may be
         based on assets subject to the Asset Value Coverage Ratio acquired
         subsequent to the end of the most recent fiscal year), (ii) to the
         knowledge of the Company no Event of Default with respect to any of
         the Notes has occurred and is continuing at the date of such
         certificate (except in the case of funds to be immediately deposited
         with Trustee pursuant to Section 4.01), and (iii) requesting a
         specific distribution.  Such chief financial officer's certificate
         shall be accompanied by an Independent Reserve Report.  Upon receipt
         of the chief financial officer's certificate and the Independent
         Reserve Report, the Trustee shall distribute the corresponding portion
         of the funds held in the Segregated Account to the Company as
         requested; provided that any chief financial officer's certificate
         delivered to the Trustee pursuant to Article Four or Article Thirteen
         shall not be required to contain the statements set forth in subparts
         (i) and (ii) above.  The Trustee shall have no obligation or liability
         to verify the truthfulness or accuracy of the chief financial
         officer's certificate or the Independent Reserve Report presented and
         likewise will have no liability for relying exclusively on such
         documents to verify the permissibility of a distribution of funds from
         the Segregated Account to the Company as requested.

                 (e)      At any time after Maturity, the Company may request
         that the Trustee distribute the funds held in the Segregated Account
         to the Company.  Upon making any such request, the Company shall
         present an Officer's Certificate including items (a) through (d) of
         Section 1.04 and stating that all principal and interest due at any
         time on the Notes up to and through Maturity has been paid to the
         Trustee.

                 (f)      The Company may at any time and from time to time
         deposit funds in the Segregated Account in order to meet the required
         Asset Value Coverage Ratio or to supplement or replace any Required
         Assets designated in the most recent chief financial officer's
         certificate as part of the Asset Value Coverage Ratio with other or
         additional assets eligible for inclusion as Required Assets, provided
         that prior to any such change in the allocation of Required Assets,
         the Company shall provide a substitute chief financial





                                       50
   52
         officer's certificate evidencing that the required Asset Value
         Coverage Ratio shall be met after such deposit, supplement or
         replacement is effective, as the case may be.

         such meeting within 21 days after receipt of such request or shall not
         thereafter proceed to cause the meeting to be held as provided herein,

         of the Notes held or represented by such Person, except that at any
         meeting, the business of which includes the modification of certain of

         on the Holders of all Coupons.

                 (f)      The Trustee may agree, without the consent of the
         Holders of the Notes or the Coupons, to any modification of, or to the
         waiver or authorization of any breach or proposed breach of, any of

         SECTION 6.14     Authenticating Agents.

                 The Principal Paying and Conversion Agent may authenticate the

                                       52

to receive all such presentations, surrenders, notices and demands.

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

         SECTION 10.03    Money for Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it will,
on or before each due date of the principal of or interest on any of the Notes,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided and
will promptly notify the Trustee of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for the
Notes, it will, on or before 3:00 p.m.  (London time) on the Business Day
immediately preceding each due date of the principal of or interest on any
Notes, deposit with a Paying Agent a sum sufficient to pay the principal or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of such action or
any failure so to act.





                                       59
   61
         Pursuant to the terms of the Agency Agreement, each Paying Agent shall
agree with the Trustee, subject to the provisions of this Section, that such
Paying Agent will:

                 (a)      hold all sums held by it for the payment of the
         principal of or interest on Notes in trust for the benefit of the
         Persons entitled thereto until such sums shall be paid to such Persons
         or otherwise disposed of as herein provided;

                 (b)      give the Trustee notice of any Default by the Company
         in the making of any payment of principal or interest; and

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

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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or interest on any
Note and remaining unclaimed for two years after such principal or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder
of such Note shall thereafter, as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

         SECTION 10.04    Corporate Existence.

         The Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence, rights
(charter and statutory) and franchises of the Company; provided, however, that
the Company shall not be required to preserve any such right





                                       60
   62
or franchise if the Board of Directors shall determine that the preservation
thereof is no longer in the best interests of the Company and its Principal
Subsidiaries as a whole and the conduct of their collective businesses, and
that the loss thereof is not disadvantageous in any material respect to the
Noteholders; and provided, further, that nothing contained in this Section
10.04 shall prohibit any transaction permitted by Article Eight or Sections
such as 10.14.

         SECTION 10.05    Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Principal
Subsidiary or upon the income, profits or property of the Company or any
Principal Subsidiary and (b) all lawful claims for labour, materials and
supplies which, if unpaid, might by law become a Lien upon the property of the
Company or any Principal Subsidiary; provided, however, that the Company shall
not be required to pay or discharge or cause to be paid or discharged any such
tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings.

         SECTION 10.06    Maintenance of Properties.

         The Company will cause all properties owned by the Company or any
Principal Subsidiary or used or held for use in the conduct of its business or
the business of any Principal Subsidiary to be maintained and kept in good
condition, repair and working order (ordinary wear and tear excepted) and
supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as
in the judgment of the Company may be necessary so that the business carried on
in connection therewith may be conducted at all times; provided, however, that
nothing in this Section shall prevent the Company from discontinuing the
maintenance of any of such properties if such discontinuance is, in the
judgment of the Company, desirable in the conduct of its business or the
business of any Principal Subsidiary and not disadvantageous in any material
respect to the Noteholders, and provided, further, that nothing contained in
this Section 10.06 shall prohibit any transaction permitted by Article Eight or
Sections such as 10.11.

         SECTION 10.07    Insurance.

         The Company will at all times keep all of the Company's and its
Principal Subsidiaries' properties which are of an insurable nature insured
with insurers, believed by the Company to be responsible, against loss or
damage to the extent that property of similar character is usually so insured
by Corporations similarly situated and owning like properties in similar
geographic areas in which the Company or such Principal Subsidiary operates;
provided that such insurance is





                                       61
   63
generally available at commercially reasonable rates, and provided further that
the Company or such Principal Subsidiary may self-insure directly or through
captive insurers or insurance cooperatives, to the extent that the Company
determines that such practice is consistent with prudent business practices.
Such insurance shall be in such amount, on such terms, in such forms and for
such periods as are customary for similarly situated Persons in the Company's
industry or in insurance markets available to the Company.

         SECTION 10.08    Statement by Officers as to Default.

         The Company will deliver to the Trustee at its Corporate Trust Office,
within 120 days after the end of each fiscal year, a brief Officers'
Certificate including a statement by the officer executing such certificate
that in the course of performing his or her duties as an officer of the Company
such officer would normally obtain knowledge of (i) whether or not any Default
exists in the performance and observation of any terms, provisions and
conditions of this Indenture and (ii) whether or not the Company has otherwise
kept, observed, performed and fulfilled its obligations under this Indenture in
all material respects.  Such Officers' Certificate shall further state, as to
the officer signing such certificate, to the knowledge of such officer, as of
the date of such Officers' Certificate, (i) whether or not any Default exists,
(ii) whether or not the Company during the preceding fiscal year kept,
observed, performed and fulfilled in all material respects each and every
covenant and obligation of the Company under this Indenture and (c) whether or
not there was any Default in the performance and observance of any of the
terms, provisions or conditions of this Indenture during such preceding fiscal
year.  If the officer signing the Officers' Certificate knows of such a
Default, whether then existing or occurring during such preceding fiscal year,
the Officers' Certificate shall describe such Default and its status with
particularity.  The Company shall also promptly notify the Trustee if the
Company's fiscal year is changed so that the end thereof is on any date other
than the then current fiscal year end date.  For purposes of this Section
10.08, such compliance shall be determined without regard to any period of
grace granted by the Trustee or requirement of notice under this Indenture.
The Company will deliver to the Trustee, forthwith upon becoming aware of any
default in the performance or observance of any covenant, agreement or
condition contained in this Indenture, or any Event of Default, an Officers'
Certificate specifying with particularity such Default or Event of Default and
further stating what action the Company has taken or is taking or proposes to
take with respect thereto.

         SECTION 10.09    Provision of Financial Statements.

         Whether or not the Company is subject to Section 13(a) or 15(d) of the
Exchange Act, the Company will, to the extent permitted under the Exchange Act,
file with the Trustee the annual reports, quarterly reports and other documents
which the Company would have been required to file with the Commission pursuant
to such Sections 13(a) or 15(d) if the Company were so subject,





                                       62
   64
such documents to be filed with the Commission on or prior to the respective
dates (the "Required Filing Dates") by which the Company would have been
required so to file such documents if the Company were so subject.  The Company
will also in any event (x) within 15 days of each Required Filing Date file
with the Trustee copies of the annual reports, quarterly reports and other
documents which the Company has filed with the Commission or would have been
required to file with the Commission pursuant to Section 13(a) or 15(d) of the
Exchange Act if the Company were subject to such Sections and (y) if filing
such documents by the Company with the Commission is not permitted under the
Exchange Act, promptly upon written request, supply copies of such documents to
any prospective Noteholder at the Company's cost.

         SECTION 10.10    Limitation on Other Indebtedness.

         Neither the Company nor any Principal Subsidiary will create, incur,
assume, guarantee or in any other manner become directly or indirectly liable
for the payment of any Indebtedness that is senior in right of payment to the
Notes.

         SECTION 10.11    Limitation on Liens.

         The Company will not, and will not permit any of its Principal
Subsidiaries to, create, incur, assume or suffer to exist, any Lien of any kind
securing any Indebtedness that is senior to, pari passu with or subordinate in
right of payment to the Notes (including any assumption, guarantee or other
liability with respect thereto by any of its Principal Subsidiaries) upon any
Oil and Gas Properties of the Company or any of its Subsidiaries described in
the Independent Reserve Report which are included in the Asset Value Coverage
Ratio, unless the Notes are equally and ratably secured or rank prior to the
Indebtedness secured by such Lien.

         SECTION 10.12    Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 8.03 or Sections 10.05
through 10.07, 10.09 through 10.11 if before or after the time for such
compliance the Holders of at least a majority in principal amount of the
Outstanding Notes, by Act of such Noteholders, waive such compliance in such
instance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.





                                       63
   65
         SECTION 10.13    Maintenance of Asset Value Coverage Ratio.

         The Company will maintain an Asset Value Coverage Ratio equal or
greater than 1:1, such maintenance to be evidenced in part based on an
Independent Reserve Report prepared as of the end of each fiscal year (as the
same may be supplemented during such fiscal year) during the term of this
Indenture.

         SECTION 10.14    Restrictions on Charter Amendments.

         The Company will not amend its Certificate of Incorporation or Bylaws
except as required by law or except to the extent that such amendment would not
have a material adverse effect on (a) the ability of the Company to perform its
obligations under this Indenture or the Notes or (b) the rights of the
Noteholders, except that neither (i) increases in the number of Shares and
issuance thereof with related securities, nor (ii) designations of Preferred
Stock of the Company, modifications of the terms of such designations and
issuance thereof with related securities, nor (iii) modification or expansion
of the indemnity provisions provided by the Company to its directors and
officers, nor (iv) change of the Company's registered agent shall be deemed an
amendment hereunder.

         SECTION 10.15    United States Withholding and Reporting Requirements.

         To the extent permitted by law, the Company will provide to the
Trustee, the Paying Agent or to any Noteholder such statements, certificates or
other documentation concerning the organization or operations of the Company as
may be reasonably necessary to establish any exceptions or exemptions from
United States federal income tax withholding and reporting requirements.


                                 ARTICLE ELEVEN

                              REDEMPTION OF NOTES

         SECTION 11.01    Right of Redemption.

         At any time after July 30, 1999, the Notes may be redeemed, at the
election of the Company, as a whole or from time to time in part.  Redemption
shall be subject to the conditions specified in the form of Note and at a
Redemption Price equal to 100% of the principal amount thereof, together with
accrued and unpaid interest to the Redemption Date, but only to the extent that
all unmatured Coupons are attached to such Notes.





                                       64
   66
         SECTION 11.02    Applicability of Article.

         Redemption of Notes at the election of the Company or otherwise, as
permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article.

         SECTION 11.03    Election to Redeem; Notice to Trustee.

         The action of the Company to redeem any Notes pursuant to Section
11.01 shall be evidenced by a Board Resolution.  In case of any redemption
pursuant to Section 11.01, the Company shall, at least 30 days and not more
than 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of
such Redemption Date and of the principal amount of Notes to be redeemed and
shall deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Notes to be redeemed pursuant to Section 11.04.

         SECTION 11.04    Selection by Trustee of Notes to Be Redeemed.

         If less than all the Notes are to be redeemed, the particular Notes to
be redeemed shall be selected not more than 60 days prior to the Redemption
Date by the Trustee, from the Outstanding Notes not previously called for
redemption, by such method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of portions of the principal
of Notes; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Note not redeemed to less than $50,000.
The Noteholders do not have a right to a prorated redemption.

         The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Notes selected for partial
redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Notes shall relate, in the
case of any Notes redeemed or to be redeemed only in part, to the portion of
the principal amount of such Note which has been or is to be redeemed.

         If the Company shall so direct, Notes registered in the name of the
Company or any Subsidiaries shall not be included in the Notes selected for
redemption.





                                       65
   67
         SECTION 11.05    Notice of Redemption.

         Notice of redemption shall be given in the manner provided for in
Section 1.08 not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Notes to be redeemed.

         All notices of redemption shall state:

                 (a)      the Redemption Date;

                 (b)      the Redemption Price;

                 (c)      if less than all Outstanding Notes are to be
         redeemed, the identification (and, in the case of a partial
         redemption, the principal amounts) of the particular Notes to be
         redeemed;

                 (d)      that on the Redemption Date the Redemption Price
         (together with accrued and unpaid interest, if any, to the Redemption
         Date payable as provided in Section 11.07, but only with respect to
         Notes with all unmatured Coupons attached) will become due and payable
         upon each such Note, or the portion thereof, to be redeemed, and that
         interest thereon will cease to accrue on and after said date;

                 (e)      the place or places where such Notes are to be
         surrendered for payment of the Redemption Price; and

                 (f)      pursuant to Section 3.13, any ISIN, CUSIP or other
         identifying numbers relating to the Notes.

         Notice of redemption of Notes to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         SECTION 11.06    Deposit of Redemption Price.

         Not less than one Business Day prior to any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.03) an amount of money sufficient to pay the Redemption
Price of, and accrued and unpaid interest on, all the Notes which are to be
redeemed on that date.





                                       66
   68
         SECTION 11.07    Notes Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Notes so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with accrued and unpaid interest,
if any, to the Redemption Date, subject to the delivery of all unmatured and
matured but unpaid Coupons), and from and after such date (unless the Company
shall default in the payment of the Redemption Price) such Notes shall cease to
bear interest.  Upon surrender of any such Note for redemption in accordance
with said notice, such Note shall be paid by the Company at the Redemption
Price, together with accrued interest, if any, to the Redemption Date, to the
extent that all matured and unpaid and unmatured Coupons, if any, are attached;
provided, however, that instalments of interest whose Stated Maturity is on or
prior to the Redemption Date shall be payable to the Holders of such Notes, or
one or more Predecessor Notes, according to their terms.

         If any Note called for redemption shall not be so paid upon surrender
by the Noteholder as prescribed hereunder thereof for redemption, the principal
shall, until paid, bear interest from the Redemption Date at the rate
prescribed therefor in the Notes.  In the event that the Company shall default
in making payment in full in respect of any Note which shall have been called
for redemption prior to July 30, 2000, on the Redemption Dates the Conversion
Right attaching to such Note will continue to be exercisable (unless previously
exercised by the Trustee or the Company) up to, and including the close of
business (at the place where the Note is deposited in connection with the
exercise of the Conversion Right) on the date upon which the full amount of the
monies payable in respect of such Note has been duly received the Trustee or
the Principal Paying Agent or, if earlier, July 30, 2000.

         SECTION 11.08    Surrender of Notes

         Each Note should be presented for redemption together with all
unmatured Coupons relating to such Note, failing which the full amount of any
missing unmatured Coupon (or, in the case of payment not being made in full,
that proportion of the full amount of the missing unmatured Coupons which the
amount so paid bears to the total amount due) will be deducted from the amount
due for payment.  Each amount so deducted will be paid in the manner mentioned
above against presentation and surrender (or, in the case of part payment only,
endorsement) of such missing Coupon at any time before the expiry of six (6)
years after the Relevant Date in respect of the relevant Note (whether or not
such Coupon would otherwise have become void pursuant to Condition 10), or if
later, five (5) years after the date on which such Coupon would have become
due, but not thereafter.

         SECTION 11.09    Conversion on Redemption





                                       67
   69

                 (a)      The Trustee may, at its absolute discretion (and
         without any responsibility for any loss occasioned thereby), within
         the period commencing on the date four (4) Business Days prior to, and
         ending at the close of business on the Business Day prior to the
         Redemption Date, of any of the Notes elect by notice in writing to the
         Company to convert as of such Redemption Date the aggregate number of
         Notes due for conversion on such date any Unexercised Notes into
         Shares at the Conversion Price applicable at such Redemption Date if
         all necessary consents (if any) have been obtained and the Trustee is
         satisfied or is advised by a reputable independent merchant bank
         appointed by it that the net proceeds of an immediate sale of the
         Shares arising from such conversion (disregarding any liability other
         than a liability of the Trustee for taxation or the payment of any
         capital, stamp, issue or registration duties consequent thereon) would
         be likely to exceed by 5 percent or more the amount of redemption
         monies and interest which would otherwise be payable in respect of
         interest accrued and unpaid since the Interest Payment Date
         immediately preceding such Redemption Date or if such date falls
         before the first Interest Payment Date, since the Closing Date in
         respect of such Unexercised Notes.

                 (b)      Subject to applicable law, the Trustee shall arrange
         for the sale on behalf of the Holders of the Unexercised Notes of the
         Shares issued on such conversion as soon as practicable, and (subject
         to any necessary consents being obtained and to the deduction by the
         Trustee of any amount which it determines to be payable in respect of
         its liability to taxation or the payment of any capital, stamp, issue
         or registration duties (if any) and any costs incurred by the Trustee
         in connection with that allotment and sale thereof) the net proceeds of
         sale together with accrued and unpaid interest payable in respect of
         such Unexercised Notes (if any) shall be held by the Trustee and
         distributed by the Principal Paying Agent rateably to the Holders of
         such Unexercised Notes against due presentation.  The amount of such
         net proceeds of sale shall be treated for all purposes as the full
         amount due by the Company in respect of such Unexercised Notes.

                                 ARTICLE TWELVE

                                   CONVERSION

         SECTION 12.01    Conversion Right and Conversion Price.

                 (a)      Subject to and upon compliance with the provisions of
         this Article, at the option of the Noteholder, at any time from and
         after the first Business Day following termination of the Restricted
         Period and (i) up to the close of business on the second Business Day
         preceding July 30, 2000 (but in no event thereafter), or (ii) if such
         Note





                                       68
   70
         shall have been called for redemption pursuant to Article Eleven, up
         to and including five (5) Business Days prior to the Redemption Date,
         provided, however, that the Company shall not have given notice of any
         Mandatory Conversion Date, any Note may be converted at the principal
         amount thereof into fully paid and non-assessable Conversion Shares at
         the Conversion Price.

                 (b)      The Conversion Price shall be adjusted in certain
         instances as provided in Section 12.04.

                 (c)      A holder of shares issued on conversion of Notes
         shall not be entitled to any rights for any Record Date which precedes
         the relevant Conversion Date or Mandatory Conversion Date, as the case
         may be.

         SECTION 12.02    Exercise of Conversion Right.

                 (a)      In order to exercise the Conversion Right, the
         Noteholder to be converted shall provide notice to the Conversion
         Agent that it intends to exercise its Conversion Right and shall
         surrender such Bearer Note or Notes and all unmatured Coupons,
         including the one for the next due interest payment, to the Conversion
         Agent at its corporate trust offices, or such other office of any
         Conversion Agent as published in an Authorized Newspaper from time to
         time, accompanied by written notice (as set forth in Exhibit E hereto)
         to the Conversion Agent that the Noteholder elects to convert such
         Note.  A Conversion Notice once delivered shall be irrevocable.

                 (b)      Bearer Notes shall be deemed to have been converted
         on the Conversion Date, and at such time, except as provided in this
         Section 12.02 below, the rights of the Noteholders as Noteholders
         shall cease, and the Person or Persons entitled to receive the Common
         Stock issuable upon conversion shall be treated for all purposes as
         the record holder or holders of such Common Stock at such time.  As
         promptly as practicable on or after the Conversion Date, the Company
         shall issue and shall deliver through the Conversion Agent at the
         Conversion Agent's office or agency a certificate or certificates for
         the number of full shares of Common Stock issuable upon such
         conversion.  The Conversion Agent shall deliver the share certificate
         or certificates in accordance with the instructions set forth in the
         notice of exercise of Conversion Rights.

                 (c)      If the Conversion Date is a date other than an
         Interest Payment Date the Company shall not pay and the Noteholder
         shall not be entitled to receive any interest accrued on the Notes
         from the last Interest Payment Date prior to the Conversion Date.





                                       69
   71
                 (d)      No Noteholder will be entitled upon conversion
         thereof to any payment or adjustment on account of interest on the
         Notes or dividends on the shares of Common Stock issued in connection
         therewith.

         SECTION 12.03    Fractions of Shares.

                 The number of Shares to be issued on conversion of a Note will
         be determined by dividing the principal amount of the Note to be
         converted by the Conversion Price in effect on the Conversion Date,
         with the result being rounded down to the nearest whole number.  No
         cash in lieu of or fractional shares of Common Stock shall be issued
         upon conversion of Notes.  If more than one Note shall be surrendered
         for conversion at one time by the same Noteholder, the number of full
         shares which shall be issuable upon conversion thereof shall be
         computed on the basis of the aggregate principal amount of the Notes
         (or specified portions thereof) so surrendered.

         SECTION 12.04    Adjustment of Conversion Price.

                 (a)      Dividends or Distributions of Common Stock.  In case
         the Company shall pay or make a dividend or other distribution on its
         Common Stock exclusively in Common Stock or shall pay or make a
         dividend or other distribution on any other class of capital stock of
         the Company which dividend or distribution includes Common Stock, the
         Conversion Price in effect at the opening of business on the day next
         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 next following the date fixed
         for such determination.  For the purposes of this Section 12.04(a),
         the number of shares of Common Stock at any time outstanding shall not
         include shares held in the treasury of the Company.

                 (b)      Dividends or Distributions of Rights, Warrants or
         Options to Purchase Common Stock.  In case the Company shall pay or
         make a dividend or other distribution on its Common Stock consisting
         exclusively of, or shall otherwise issue to all holders of its Common
         Stock, rights, warrants or options entitling the holders thereof to
         subscribe for or purchase shares of Common Stock at a price per share
         less than the Market Price per share (determined as provided in
         Section 12.04(g)) of the Common Stock on the date fixed for the
         determination of stockholders entitled to receive such rights,
         warrants or options,





                                       70
   72
         the Conversion Price in effect at the opening of business on the day
         following the date fixed for such determination 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 plus the number
         of shares of Common Stock which the aggregate of the offering price of
         the total number of shares of Common Stock so offered for subscription
         or purchase would purchase at such Market Price and the denominator
         shall be the number of shares of Common Stock outstanding at the close
         of business on the date fixed for such determination plus the number
         of shares of Common Stock so offered for subscription or purchase,
         outstanding at the close of business on the date fixed for such
         reduction to become effective immediately after the opening of
         business on the day following the date fixed for such determination.
         For the purposes of this paragraph (b), the number of shares of Common
         Stock at any time outstanding shall not include shares held in the
         treasury of the Company.  The Company shall not issue any rights,
         warrants or options in respect of shares of Common Stock held in the
         treasury of the Company.

                 (c)      Dividends or Distributions in Cash.  In case the
         Company shall, by dividend or otherwise, make a distribution to all
         holders of its Common Stock exclusively in cash in an aggregate amount
         that, together with (i) the aggregate amount of any other
         distributions to all holders of its Common Stock made exclusively in
         cash within the 12 months preceding the date of payment of such
         distribution and in respect of which no Conversion Price adjustment
         pursuant to this Section 12.04(c) has been made and (ii) the aggregate
         of any cash plus the fair market value (as determined in good faith by
         the Board of Directors, whose determination shall be conclusive and
         described in a resolution of the Company's Board of Directors), as of
         the expiration of the tender or exchange offer referred to below, of
         consideration payable in respect of any tender or exchange offer by
         the Company or a Subsidiary for all or any portion of the Common Stock
         concluded within the 12 months preceding the date of payment of such
         distribution and in respect of which no Conversion Price adjustment
         pursuant to paragraph (f) of this Section 12.04 has been made, exceeds
         five percent (5%) of the product of the Market Price per share
         (determined as provided in Section 12.04(g)) of the Common Stock on
         the date fixed for stockholders entitled to receive such distribution
         times the number of shares of Common Stock outstanding on such date,
         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 effectiveness of the Conversion Price
         reduction contemplated by this paragraph (c) by a fraction of which
         the numerator shall be the Market Price per share (determined as
         provided Section 12.04(g)) of the Common Stock on the date of such
         effectiveness less the amount of cash so distributed applicable to one
         share of Common Stock and the denominator shall be such Market Price
         per share of the Common Stock, such reduction





                                       71
   73
         to become effective immediately prior to the opening of business on
         the day following the date fixed for the payment of such distribution.

                 (d)      All Other Distributions or Dividends.  Subject to the
         last sentence of this paragraph (d), in case the Company shall, by
         dividend or otherwise, distribute to all holders of its Common Stock
         evidences of its indebtedness, shares of any class of capital stock,
         securities, cash or property (excluding any rights, warrants or
         options referred to in Section 12.04(b), any dividend or distribution
         paid exclusively in cash and any dividend or distribution referred to
         in Section 12.04(a), 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 effectiveness of the
         Conversion Price reduction contemplated by this paragraph (d) by a
         fraction of which the numerator shall be the Market Price per share
         (determined as provided in paragraph (g) of this Section) of the
         Common Stock on the date of such effectiveness less the fair market
         value (as determined in good faith by the Board of Directors, whose
         determination shall be conclusive and described in a resolution of the
         Company's Board of Directors and shall, in the case of securities
         being distributed for which prior thereto there is an actual or when
         issued trading market, be no less than the value determined by
         reference to the average of the Market Price over the period specified
         in the succeeding sentence), on the date of such effectiveness, of the
         portion of the evidences of indebtedness, shares of capital stock,
         securities, cash and property so distributed applicable to one share
         of Common Stock and the denominator shall be such Market Price per
         share of the Common Stock, such reduction to become effective
         immediately prior to the opening of business on the day next following
         the date fixed for the payment of such distribution (such date to
         being referred to as the "Reference Date").  If the Board of Directors
         determines the fair market value of any distribution for purposes of
         this paragraph (d) by reference to the actual or when issued trading
         market for any securities comprising such distribution, it must in
         doing so consider the prices in such market over the same period used
         in computing the Market Price per share pursuant to paragraph (g) of
         this Section.  For purposes of this paragraph (d), any dividend or
         distribution that includes shares of Common Stock or rights, warrants
         or options to subscribe for or purchase shares of Common Stock shall
         be deemed instead to be (i) a dividend or distribution of the
         evidences of indebtedness, cash, property, shares of capital stock or
         securities other than such shares of Common Stock or such rights,
         warrants or options (making any Conversion Price reduction required by
         this paragraph (d)) immediately followed by (ii) a dividend or
         distribution of such shares of Common Stock or such rights, warrants
         or options (making any further Conversion Price reduction required by
         Section 12.04(a) or (b)), except (i) the Reference Date of such
         dividend or distribution as defined in this Section 12.04(d) shall be
         substituted as "the date fixed for the determination of stockholders
         entitled to receive such dividend or other distribution",





                                       72
   74
         "the date fixed for the determination of stockholders entitled to
         receive such rights, warrants or options" and "the date fixed for such
         determination" within the meaning of Section 12.04(a) and (b) and (ii)
         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 12.04(a)).

                 (e)      Subdivision of Common Stock.  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 each 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.

                 (f)      Tender or Exchange Offer for Common Stock.  In case a
         tender or exchange offer made by the Company or any Subsidiary for all
         or any portion of the Common Stock shall expire and such tender or
         exchange offer shall involve an aggregate consideration having a fair
         market value (as determined in good faith by the Board of Directors,
         whose determination shall be conclusive and described in a resolution
         of the Company's 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 may be amended) that, together with (i) the
         aggregate of the cash plus the fair market value (as determined in
         good faith by the Board of Directors, whose determination shall be
         conclusive and described in a resolution of the Company's Board of
         Directors), as of the expiration of the other tender or exchange offer
         referred to below, of consideration payable in respect of any other
         tender or exchange offer by the Company or a Subsidiary for all or any
         portion of the Common Stock concluded within the preceding 12 months
         and in respect of which no Conversion Price adjustment pursuant to
         this paragraph (f) has been made and (ii) the aggregate amount of any
         distributions to all holders of the Common Stock made exclusively in
         cash within the preceding 12 months and in respect of which no
         Conversion Price adjustment pursuant to Section 12.04(e) has been
         made, exceeds five percent (5%) of the product of the Market Price per
         share (determined as provided in Section 12.04(g)) of the Common Stock
         on the Expiration Time times the number of shares of Common Stock
         outstanding (including any tendered shares) on the Expiration Time,
         the Conversion Price shall be reduced (but not increased) 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





                                       73
   75
         numerator shall be (i) the product of the Market Price per share
         (determined as provided in Section 12.04(g)) of the Common Stock at
         the Expiration Time times the number of shares of Common Stock
         outstanding (including any tendered or exchanged shares) at the
         Expiration Time minus (ii) 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 the denominator shall be the product of (i)
         such Market Price per share at the Expiration Time times (ii) such
         number of outstanding shares at the Expiration Time less the number of
         Purchased Shares, such reduction to become effective immediately prior
         to the opening of business on the day following the Expiration Time.

                 (g)      Determination of Market Price.  For the purpose of
         any computation of the Market Price under this paragraph (g) and
         Section 12.04(b), (d) and (e), (i) if the "ex" date (as hereinafter
         defined) for any event (other than the issuance or distribution
         requiring such computation) that requires an adjustment to the
         Conversion Price pursuant to paragraph (a), (b), (c), (d), (e) or (f)
         above ("Other Event") occurs on or after the tenth Stock Exchange
         Business Day prior to the date in question and prior to the "ex" date
         for the issuance or distribution requiring such computation (the
         "Current Event"), the closing price for each Stock Exchange Business
         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, (ii) if the "ex" date for any Other Event occurs after
         the "ex" date for the Current Event and on or prior to the date in
         question, the closing price for each Stock Exchange Business 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, (iii) if the "ex" date for any Other Event occurs
         on the "ex" date for the Current Event, one of those events shall be
         deemed for purposes of clauses (i) and (ii) of this proviso to have an
         "ex" date occurring prior to the "ex" date for the other event, and
         (iv) if the "ex" date for the Current Event is on or prior to the date
         in question, after taking into account any adjustment required
         pursuant to clause (ii) of this proviso, the closing price for each
         Stock Exchange Business Day on or after such "ex" date shall be
         adjusted by adding thereto the amount of any cash and the fair market
         value on the date in question (as determined in good faith by the
         Board of Directors in a manner consistent with any determination of
         such value for purposes of this Section 12.04(c) or (d), whose
         determination shall be conclusive and described in a resolution of the
         Company's Board of Directors) of the portion of the rights, warrants,
         options, evidences of indebtedness, shares of capital stock,
         securities, cash or property being distributed





                                       74
   76
         applicable to one share of Common Stock.  For the purpose of any
         computation under Section 12.04(f), the Market Price per share of
         Common Stock on any date in question shall be deemed to be the Market
         Price on the date selected by the Company commencing on or after the
         latest (the "Commencement Date") of (i) the date 20 Stock Exchange
         Business Days before the date in question, (ii) the date of
         commencement of the tender or exchange offer requiring such
         computation and (iii) the date of the last amendment, if any, of such
         tender or exchange offer involving a change in the maximum number of
         shares for which tenders are sought or a change in the consideration
         offered, and ending not later than the date of the Expiration Time of
         such tender or exchange offer (or, if such Expiration Time occurs
         before the close of trading on a Stock Exchange Business Day, not
         later than the Stock Exchange Business Day immediately preceding the
         date of such Expiration Time); provided, however, that if the "ex"
         date for any Other Event (other than the tender or exchange offer
         requiring such computation) occurs on or after the Commencement Date
         and on or prior to the date of the Expiration Time for the tender or
         exchange offer requiring such computation, the closing price for each
         Stock Exchange Business 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.  For purposes of this paragraph, the
         term "ex" date, (i) 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, (ii) 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 (iii) 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 tender or exchange offer.

                 (h)      Further Reductions for Federal Income Tax.  The
         Company may make such reductions in the Conversion Price, in addition
         to those required by Section 12.04 (a), (b), (c), (d), (e) and (f), as
         it considers to be advisable in order that any event treated for
         Federal income tax purposes as a dividend of stock or stock rights
         shall not be taxable to the recipients.

                 (i)      Adjustments to be Carried Forward.  No adjustment in
         the Conversion Price shall be required unless such adjustment would
         require an increase or decrease of at least five percent (5%) in the
         Conversion Price; provided, however, that any adjustments which by
         reason of this paragraph (j) are not required to be made shall be
         carried forward and taken into account in any subsequent adjustment.

         SECTION 12.05    Notice of Adjustments of Conversion Price.

         Whenever the Conversion Price is adjusted as herein provided the
Company shall compute the adjusted Conversion Price in accordance with Section
12.04 and shall prepare a certificate signed by the chief financial officer of
the Company setting forth the adjusted Conversion Price and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be delivered to the Trustee, the Paying Agent and
the Conversion Agent, and the Company shall cause notice thereof to be
published in accordance with Section 1.08 within ten (10) Business Days of the
effective date of such adjustment.

         SECTION 12.06    Notice of Certain Corporate Action.

         In case:

                 (a)      the Company shall declare a dividend (or any other
         distribution) on its Common Stock payable (i) otherwise than
         exclusively in cash or (ii) exclusively in cash in an amount that
         would require a Conversion Price adjustment pursuant to Section
         12.04(c); or

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

                 (c)      of any reclassification of the Common Stock of the
         Company (other than a subdivision or combination of its outstanding
         shares of Common Stock), or of any consolidation or merger to which
         the Company is a party and for which approval of any stockholders 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; or

                 (e)      the Company or any Subsidiary of the Company shall
         commence a tender or exchange offer for all or a portion of the
         Company's outstanding shares of Common Stock (or shall amend any such
         tender or exchange offer);

then the Company shall cause to be mailed to the Trustee, the Paying Agent, the
Conversion Agent and to be published in the manner provided under Section 1.08
hereof within ten (10) Business Days after the date on which notice is sent to
the holders of the Company's Common Stock, a





                                       76
   78
notice stating (i) the date on which a record is to be taken for the purpose of
such dividend, distribution or granting of rights, warrants or options, or, if
a record is not to be taken, the date as of which the holders of Common Stock
of record to be entitled to such dividend, distribution, rights, warrants or
options are to be determined, or (ii) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up
is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such re-
classification, consolidation, merger, sale, transfer, dissolution, liquidation
or winding up, or (iii) the date on which such tender offer commenced, the date
on which such tender offer is scheduled to expire unless extended, the
consideration offered and the other material terms thereof (or the material
terms of any amendment thereto).

         SECTION 12.07    Company to Reserve Common Stock.

         The Company shall at all times reserve and keep available, free from
pre-emptive or similar rights, out of its authorized but unissued Common Stock,
solely for the purpose of effecting the conversion of Notes, the whole number
of Shares then issuable upon the conversion in full of all Outstanding Notes.

         SECTION 12.08    Taxes on Conversions.

         The Company will pay any and all taxes that may be payable in respect
of the issue or delivery of Shares on conversion of Notes pursuant hereto. 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 Shares in a name
other than that of the Holder of the Notes to be converted, and no such issue
or delivery shall be made unless and until the Person requesting such issue has
paid to the Company the amount of any such tax, or has established to the
satisfaction of the Company that such tax has been paid.

         SECTION 12.09    Cancellation of Converted Bearer Notes.

         All Bearer Notes delivered for conversion to the Conversion Agent
shall be cancelled by the Company, and shall not under any circumstances be
reissued.





                                       77
   79
         SECTION 12.10    Provisions in Case of Reclassification Consolidation,
                          Merger or Sale of Assets.

         In the event that the Company shall be a party to any transaction
(including without limitation any (i) recapitalization or reclassification of
the Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination of the Common Stock), (ii) any consolidation of the Company with,
or merger of the Company into, any other person, any merger of another person
into the Company (other than a merger which does not result in a
reclassification, conversion, exchange or cancellation of all of the
outstanding shares of Common Stock of the Company), (iii) any sale or transfer
of all or substantially all of the assets of the Company, or (iv) any
compulsory share exchange pursuant to which the Common Stock is converted into
the right to receive other securities, cash or other property, then lawful
provision shall be made as part of the terms of such transaction whereby the
Holder of each Note then outstanding shall have the right thereafter to convert
such Note only into the kind of common stock receivable upon such transaction
by a holder of Common Stock (at an adjusted Conversion Price equal to (a) the
Conversion Price determined pursuant to Section 12.04 as though all such
securities, cash or property (other than common stock) had been distributed in
a dividend covered by Section 12.04(d) with an "ex" date on the date of such
transaction divided by (b) the number of shares (or fraction thereof) of common
stock receivable upon such transaction in respect of each share of Common
Stock).  The Person formed by such consolidation or resulting from such merger
or which acquired such assets or which acquired the Company's Shares, as the
case may be, shall execute and deliver to each of the Noteholders an amendment
to this Indenture as provided for under Article Nine.  Such amendment shall
provide for adjustments which, for events subsequent to the effective date of
such amendment, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article and shall provide for the assumption
by such other Person, if any, of the Company's obligations under this Indenture
and the Notes.  The above provisions of this Section 12.10 shall similarly
apply to successive transactions of the foregoing type.

         SECTION 12.11    Mandatory Conversion.

         At any time after July 30, 1997, the Notes may be converted in whole,
at the Company's option, if at any time the Market Price of the Common Stock
shall have equalled or exceeded 135% of the Conversion Price in effect on such
Stock Exchange Business Day on each Stock Exchange Business Day in any 30
consecutive calendar day period, the first day of which falls on or after
November 28, 1996.  In the event that the Company has met the criteria for
Mandatory Conversion at any time, the Company shall give notice to the
Noteholders in the manner provided for in Section 1.08 within 30 calendar days
of the date on which such criteria has been met.





                                       78
   80
         At any time after July 30, 1997, the Company may require such
Noteholders to convert all of such Notes otherwise pursuant to the terms of
this Article.  The Company shall deliver to the Trustee a notice in the form of
Exhibit F hereto and the Company shall cause to be published once in accordance
with Section 1.08 hereof a notice of Mandatory Conversion not less than thirty
(30) and not more than (60) calendar days prior to the Mandatory Conversion
Date.  Such notice shall specify the Mandatory Conversion Date.  After the
Mandatory Conversion Date, the Notes will no longer represent Indebtedness of
the Company and will no longer accrue interest or require the Company to make
any payment of principal; and the Company's obligations to make any further
payments with respect to the Notes will terminate (except for this Section
12.11 and the Section 12.02(c)); and the only rights of a Holder of a Note not
surrendered for conversion pursuant to the preceding sentence will be to (i)
receive the number of Conversion Shares such Noteholder would have received had
the Holder's Note or Notes been surrendered for conversion as required hereby,
(ii) the payment referred to in Section 12.02(c) and (iii) the payment referred
to in Section 12.03.  Any notice which is published in the manner herein
provided shall be conclusively presumed to be given and any defect in such
notice to the Noteholder designated for required conversion shall not affect
the validity of the proceedings for the required conversion of any other Bearer
Note.


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 13.01    Company's Option to Effect Defeasance or Covenant
                          Defeasance.

         The Company may, at its option by Board Resolution, at any time, with
respect to the Notes, elect to have either Section 13.02 or Section 13.03 be
applied to all Outstanding Notes upon compliance with the conditions set forth
below in this Article.  The Company shall promptly give notice of such election
to the Trustee.

         SECTION 13.02    Legal Defeasance and Discharge.

         Upon the Company's exercise under Section 13.01 of the option
applicable to this Section 13.02, the Company shall be deemed to have been
discharged from its obligations with respect to all Outstanding Notes on the
date the conditions set forth in Section 13.04 are satisfied (hereinafter,
"legal defeasance").  For this purpose, such legal defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Notes, which shall thereafter be deemed to be
"Outstanding" only for the purposes of Section 13.05 and the other Sections of
this Indenture referred to in (A) and (B) below, and to





                                       79
   81
have satisfied all its obligations under such Notes, including the obligation
to pay interest on the Notes, and this Indenture insofar as such Notes are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder:  (A) the rights of
Holders of Outstanding Notes to receive, solely from the trust fund described
in Section 13.04 and as more fully set forth in such Section, payments in
respect of the principal of and interest on such Notes when such payments are
due, (B) the Company's obligations with respect to such Notes under Sections
3.04, 3.05, 3.08, 10.02 and 10.03 and with respect to the Trustee under Section
6.06, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article.  Subject to compliance with this Article, the
Company may exercise its option under this Section 13.02 notwithstanding the
prior exercise of its option under Section 13.03 with respect to the Notes.

         SECTION 13.03    Covenant Defeasance.

         Upon the Company's exercise under Section 13.01 of the option
applicable to this Section 13.03, the Company shall be released from its
obligations under any covenant contained in Sections 10.04 through 10.15 with
respect to the Outstanding Notes on and after the date the conditions set forth
in Section 13.04 are satisfied (hereinafter, "covenant defeasance"), and the
Notes shall thereafter be deemed not to be "Outstanding" for the purposes of
any request, demand, authorization, direction, declaration, notice, consent,
waiver or Act of Noteholders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder.  For this purpose, such covenant defeasance
means that, with respect to the Outstanding Notes, the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any
other document and such omission to comply shall not constitute a Default or an
Event of Default under Section 5.01(d), but, except as specified above, the
remainder of this Indenture and such Notes shall be unaffected thereby.

         SECTION 13.04    Conditions to Legal Defeasance or Covenant
                          Defeasance.

         The following shall be the conditions to application of either Section
13.02 or Section 13.03 to the Outstanding Notes:

                 (a)      The Company shall irrevocably have deposited or
         caused to be deposited with the Trustee (or another trustee satisfying
         the requirements of Section 6.07 who shall agree to comply with the
         provisions of this Article applicable to it) as trust funds in trust





                                       80
   82
          for the purpose of making the following payments, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of such Notes, (A) money, which may include funds distributed
         from the Seggregated Account, in an amount, or (B) U.S. Government
         Obligations which through the scheduled payment of principal and
         interest in respect thereof in accordance with their terms will
         provide, not later than one day before the due date of any payment,
         money in an amount, or (C) a combination thereof, sufficient, in the
         opinion of a nationally recognized firm of independent public
         accountants expressed in a written certification thereof delivered to
         the Trustee, to pay and discharge, and which shall be applied by the
         Trustee (or other qualifying trustee) to pay and discharge, the
         principal of and interest on the Outstanding Notes on the Stated
         Maturity (or Redemption Date, if applicable) of such principal or
         instalment of interest; provided that the Trustee shall have been
         irrevocably instructed to apply such money or the proceeds of such
         U.S. Government Obligations to said payments with respect to the
         Notes; and provided further that, upon the effectiveness of this
         Section 13.04, the money or U.S. Government Obligations deposited
         shall not be subject to the rights of the Noteholders pursuant to the
         provisions of this Article.  Before or after such a deposit, the
         Company may give to the Trustee, in accordance with Section 11.03
         hereof, a notice of its election to redeem all of the Outstanding
         Notes at a future date in accordance with Article Eleven hereof, which
         notice shall be irrevocable.  Such irrevocable redemption notice, if
         given, shall be given effect in applying the foregoing.

                 (b)      No Default or Event of Default with respect to the
         Notes shall have occurred and be continuing on the date of such
         deposit or, insofar as paragraphs (h) and (i) of Section 5.01 hereof
         are concerned, at any time during the period ending on the 91st day
         after the date of such deposit (it being understood that this
         condition shall not be deemed satisfied until the expiration of such
         period).

                 (c)      No event or condition shall exist that pursuant to
         the provisions of Section 13.02 or 13.03 would prevent the Company
         from making payments of the principal of or interest on the Notes on
         the date of such deposit or at any time during the period ending on
         the 91st day after the date of such deposit (it being understood that
         this condition shall not be deemed satisfied until the expiration of
         such period).

                 (d)      Such legal defeasance or covenant defeasance shall
         not result in a breach or violation of, or constitute a default under
         any material agreement or instrument to which the Company is a party
         or by which it is bound.

                 (e)      In the case of an election under Section 13.02, the
         Company shall have delivered to the Trustee an Opinion of Counsel
         stating that  the Holders of the Outstanding





                                       81
   83
         Notes will not recognize income, gain or loss for federal income tax
         purposes as a result of such defeasance and will be subject to federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such defeasance had not occurred.

                 (f)      The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the legal
         defeasance under Section 13.02 or the covenant defeasance under
         Section 13.03 (as the case may be) have been complied with.

         SECTION 13.05    Deposited Money and U.S. Government Obligations to Be
                          Held in Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 10.03, all
money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee--collectively for
purposes of this Section 13.05, the "Trustee") pursuant to Section 13.04 in
respect of the Outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Notes of all sums due and to become due thereon in respect of principal
and interest, but such money and U.S. Government Obligations need not be
segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 13.04 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Outstanding Notes.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 13.04
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent legal defeasance or covenant defeasance, as
applicable, in accordance with this Article.





                                       82
   84
         SECTION 13.06    Reinstatement.

         If the Trustee or any Paying Agent is unable to apply any money or
U.S. Government Obligations in accordance with Section 13.05 by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the Company's obligations under
this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 13.02 or 13.03, as the case may be,
until such time as the Trustee or Paying Agent is permitted to apply all such
money or U.S. Government Obligations in accordance with Section 13.05;
provided, however, that no action taken in good faith by the Company after a
deposit of money or U.S. Government Obligations or both pursuant to Section
13.05 and prior to the revival and reinstatement of obligations under this
Indenture and the Notes pursuant to this Section 13.06 shall constitute the
basis for the assertion of an Event of Default pursuant to Section 5.01; and
provided, further, that if the Company makes any payment of principal of or
interest on 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 or U.S. Government Obligations held by the
Trustee or Paying Agent.


                                ARTICLE FOURTEEN

                               SENIORITY OF NOTES

         SECTION 14.01    Seniority of the Notes.

         The Company's obligations under the Notes and the Coupons and
hereunder do and will rank at all times at least pari passu with all other
present and future Indebtedness of the Company and shall be superior in rank to
all existing and future Subordinated Obligations.  The Company covenants and
agrees that, except with respect to any Lien, the Indebtedness represented by
the Notes and the Coupons and the payment of the principal of and interest on
each and all of the Notes and Coupons are hereby expressly made pari passu to
all other present and future Indebtedness other than all Subordinated
Obligations.

                      STOCKHOLDERS, OFFICERS AND DIRECTORS

         SECTION 15.01    Liability Solely Corporate.

         No recourse shall be had for the payment of the principal of or
interest on any Notes or any part thereof, or for any claim based thereon or
otherwise in respect thereof, or of the indebtedness represented thereby, or
upon any obligation, covenant or agreement of this Indenture, against any
incorporator, or against any stockholder, officer or director, as such, past,
present or future, of the Company, or of any predecessor or successor Person,
either directly or through the Company or any such predecessor or successor
Person, 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
agreed and understood that this Indenture and all the Notes are solely
corporate obligations, and that no personal liability whatsoever shall attach
to, or be insured by, any such incorporator, stockholder, officer or director,
as such, past, present or future, of the Company or of any predecessor or
successor Person, either directly or through the Company or any such
predecessor or successor Person, because of the indebtedness hereby authorized
or under or by reason of any of the obligations, covenants, promises or
agreements contained in this Indenture or in any of the Notes or to be implied
herefrom or therefrom; and that any such personal liability is hereby expressly
waived and released as a condition of, and as part of the consideration for,
the execution of this Indenture and the issue of the Notes; provided, however,
that nothing herein or in the Notes contained shall be taken to prevent
recourse to and the enforcement of the liability, if any, of any stockholder or
subscriber to capital stock of the Company upon or in respect of shares of
capital stock not fully paid up.

         This Indenture may be signed in any number of counterparts each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same Indenture.

be duly executed, all as of the day and year first above written.
