Securities presented to the Trustee by the Property Trustee having an aggregate
principal amount equal to the aggregate liquidation amount of the Non Book-Entry
Preferred Securities until such Preferred Security certificates are presented to
the Security Registrar for transfer or reissuance, at which time such Preferred
Security certificates will be canceled and a Security, registered in the name of
the holder of the Preferred Security certificate or the transferee of the holder
of such Preferred Security certificate, as the case may be, with an aggregate
principal amount equal to the aggregate liquidation amount of the Preferred
Security certificate canceled, will be executed by the Company and delivered to
the Trustee for authentication and delivery in accordance with this Indenture.
Upon the issuance of such Securities, Securities with an equivalent aggregate
principal amount that were presented by the Property Trustee to the Trustee will
be canceled.

     (b)  The Global Securities shall represent the aggregate principal amount
of outstanding Securities from time to time endorsed thereon; provided, that the
aggregate principal amount of outstanding Securities represented thereby may
from time to time be reduced or increased, as appropriate, to reflect exchanges
and redemptions. Any endorsement of a Global Security to reflect the amount of
any increase or decrease in the principal amount of outstanding Securities
represented thereby shall be made by the Trustee, in accordance with
instructions given by the Company as required by this Section 2.04.

     (c)  The Global Securities may be transferred, in whole but not in part,
only to the Depositary, another nominee of the Depositary, or to a successor
Depositary selected or approved by the Company or to a nominee of such successor
Depositary.

     (d)  If at any time the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary or the Depositary has ceased to be
a clearing agency registered under the Exchange Act or any applicable statute or
regulation, and a successor Depositary is not appointed by the Company within 90
days after the Company receives such notice or becomes aware of such condition,
as the case may be, the Company will execute, and the Trustee, upon receipt of a
Company Order, will authenticate and make available for delivery the Definitive
Securities, in authorized denominations, and in an aggregate principal amount
equal to the principal amount of the Global Security in exchange for such Global
Security. If there is an Event of Default, the Depositary shall have the right
to exchange the Global Securities for Definitive Securities. In addition, the
Company may at any time determine that the Securities shall no longer be
represented by a Global Security. In the event of such an Event of Default or
such a determination, the Company shall execute, and subject to Section 2.06,
the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company and a Company Order, will authenticate and make
available for delivery the Definitive Securities, in authorized denominations,
and in an aggregate principal amount

                                       12

<PAGE>

equal to the principal amount of the Global Security in exchange for such Global
Security. Upon the exchange of the Global Security for such Definitive
Securities, in authorized denominations, the Global Security shall be canceled
by the Trustee. Such Definitive Securities issued in exchange for the Global
Security shall be registered in such names and in such authorized denominations
as the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Definitive Securities to the Depositary for delivery to the Persons in
whose names such Definitive Securities are so registered.

SECTION 2.05     Interest.
                 --------

         (a) Each Security will bear interest at the rate of ____% per annum
(the "Coupon Rate") from the most recent date to which interest has been paid or
duly provided for or, if no interest has been paid or duly provided for, from
_______________,____, until the principal thereof becomes due and payable, and
at the Coupon Rate on any overdue principal (and premium, if any) and (to the
extent that payment of such interest is enforceable under applicable law) on any
overdue installment of interest, compounded [semi- annually], payable (subject
to the provisions of Section 2.13) [semi-annually] in arrears on [_________ and
_______] of each year (each, an "Interest Payment Date") commencing on
___________, ___, to the Person in whose name such Security or any predecessor
Security is registered, at the close of business on the regular record date for
such interest installment, [which shall be the fifteenth day of the month
immediately preceding the month in which the relevant Interest Payment Date
falls.]

         (b) Interest will be computed on the basis of a 360-day year consisting
of twelve 30-day months and, for any period of less than a full calendar month,
the number of days lapsed in such month. In the event that any Interest Payment
Date falls on a day that is not a Business Day, then payment of interest payable
on such date will be made on the next succeeding day which is a Business Day
(and without any interest or other payment in respect of any such delay), except
that if such next succeeding Business Day falls in the next succeeding calendar
year, then such payment shall be made on the immediately preceding Business Day,
in each case with the same force and effect as if made on the date such payment
is otherwise required.

         (c) During such time as the Property Trustee is the holder of any
Securities, the Company shall pay any additional amounts on the Securities as
may be necessary in order that the amount of Distributions then due and payable
by the Trust on the outstanding Trust Securities shall not be reduced as a
result of any additional taxes, duties and other governmental charges to which
the Trust has become subject as a result of a Tax Event ("Additional Sums").

         (d) Interest on any Security which is payable, and which is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person is whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the record date for such interest
installment.

         (e) [In the case of any Security which is converted on or after any
regular record date and on or prior to the next succeeding Interest Payment Date
(other than any Security whose maturity is prior to such Interest Payment Date),
interest whose due date is on such Interest Payment Date shall be payable on
such Interest Payment Date notwithstanding such conversion, and such interest

                                       13

<PAGE>

(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Security is registered at the close of business on
such record date. Except as otherwise expressly provided in the immediately
preceding sentence, in the case of any Security that is converted prior to any
record date, interest whose due date is after the date of conversion of such
Security shall not be payable, and the Company shall not make nor be required to
make any other payment, adjustment or allowance with respect to accrued but
unpaid interest (including Additional Sums or Compounded Interest) on the
Securities being converted, which shall be deemed to be paid in full.]

SECTION 2.06    Transfer and Exchange.
                ---------------------

         (a)  The Company shall maintain an office or agency where the
Securities may be presented for registration of transfer or for exchange (the
"Security Registrar"). The Company initially appoints the Trustee as Security
Registrar.

         (b)  To permit registrations of transfers and exchanges, the Company
shall execute and the Trustee shall authenticate Definitive Securities and
Global Securities in any authorized denomination and of a like aggregate
principal amount at the Security Registrar's request. All Definitive Securities
and Global Securities issued upon any registration of transfer or exchange of
Definitive Securities or Global Securities shall be the valid obligations of the
Company, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Definitive Securities or Global Securities surrendered upon
such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
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 a form that is
satisfactory to the Company and the Security Registrar duly executed by the
holder thereof or his attorney duly authorized in writing.

         No service charge shall be made to a holder for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any transfer tax or similar governmental charge payable in connection
therewith.

         The Company shall not be required to (i) issue, register the transfer
of or exchange Securities during a period beginning at the opening of business
15 days before the day of mailing of a notice of redemption or any notice of
selection of Securities for redemption under Article X hereof and ending at the
close of business on the day of such mailing; or (ii) register the transfer of
or exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

         The transfer and exchange of beneficial interests in a Global Security,
which does not involve the issuance of a Definitive Security or the transfer of
an interest to another Global Security, shall be effected through the Depositary
(but not the Trustee) in accordance with the procedures of the Depositary
therefor. The Trustee will not have any responsibility for the transfer and
exchange of beneficial interests in such Global Security that does not involve
the issuance of a Definitive Security or the transfer of interests to another
Global Security.

                                       14

<PAGE>

         Prior to due presentment for the registration of a transfer of any
Security, the Trustee, the Company and any agent of the Trustee or the Company
may deem and treat the Person in whose name any Security is registered as the
absolute owner of such Security for the purpose of receiving payment of
principal of and premium, if any, and interest on such Securities, neither the
Trustee, nor the Company nor any agent of the Trustee or the Company shall be
affected by notice to the contrary.

SECTION 2.07   Replacement Securities.
               ----------------------

         If any mutilated Security is surrendered to the Trustee, or the Company
and the Trustee receive evidence to their satisfaction of the destruction, loss
or theft of any Security, the Company shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's requirements for
replacements of Securities are met. A holder requesting such replacement
Security shall supply an indemnity bond or other security that is sufficient in
the judgment of the Trustee and the Company to protect the Company, the Trustee,
any agent thereof or any authenticating agent from any loss that any of them may
suffer if a Security is replaced. The Company or the Trustee may charge for its
expenses in replacing a Security.

         Every replacement Security is an obligation of the Company and shall be
entitled to all of the benefits of this Indenture equally and proportionately
with all other Securities duly issued hereunder.

SECTION 2.08   Temporary Securities.
               --------------------

         Pending the preparation of Definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, temporary Securities that are printed, lithographed,
typewritten, mimeographed or otherwise reproduced, in any authorized
denomination, substantially of the tenor of the Definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as conclusively evidenced by their execution of such Securities.

         If temporary Securities are issued, the Company shall cause Definitive
Securities to be prepared without unreasonable delay. The Definitive Securities
shall be printed, lithographed or engraved, or provided by any combination
thereof, or in any other manner permitted by the rules and regulations of any
applicable securities exchange, all as determined by the officers executing such
Definitive Securities. After the preparation of Definitive Securities, the
temporary Securities shall be exchangeable for Definitive Securities upon
surrender of the temporary Securities at the office or agency maintained by the
Company for such purpose pursuant to Section 3.02 hereof, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Securities,
the Company shall execute, and the Trustee shall authenticate and make available
for delivery, in exchange therefor the same aggregate principal amount of
Definitive Securities of authorized denominations. Until so exchanged, the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as Definitive Securities.

                                       15

<PAGE>

SECTION 2.09     Cancellation.
                 ------------

         The Company at any time may deliver Securities to the Trustee for
cancellation. The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall retain or destroy canceled Securities in accordance with
its normal practices (subject to the record retention requirement of the
Exchange Act) unless the Company directs them to be returned to it. The Company
may not issue new Securities to replace Securities that have been redeemed or
paid or that have been delivered to the Trustee for cancellation.

         All Securities surrendered for payment, redemption, [conversion,]
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
Notwithstanding any other provision of this Indenture, the Company may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section 2.9, except as expressly
permitted by this Indenture. All canceled Securities shall be destroyed by the
Trustee and the Trustee shall deliver to the Company a certificate of such
destruction.

SECTION 2.10     Defaulted Interest.
                 ------------------

         Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the holder on the
relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Company, at its election, as provided in
clause (a) or clause (b) below:

         (a)  The Company may make payment of any Defaulted Interest on
Securities to the Persons in whose names such Securities (or their respective
Predecessor Securities) are registered at the close of business on a special
record date for the payment of such Defaulted Interest, which shall be fixed in
the following manner: the Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each such Security and the
date of the proposed payment, and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this clause provided.
Thereupon the Trustee shall fix a special record date for the payment of such
Defaulted Interest which shall not be more than 15 nor less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt
by the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such special record date and, in the name and at the
expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the special record date therefor to be mailed, first
class postage prepaid, to each Securityholder at his or her address as it
appears in the Security Register, not less than 10 days prior to such special
record date. Notice of the proposed payment of such

                                       16

<PAGE>

Defaulted Interest and the special record date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the Persons in whose names
such Securities (or their respective Predecessor Securities) are registered on
such special record date and shall be no longer payable pursuant to the
following clause (b).

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

SECTION 2.11     CUSIP Numbers.
                 -------------

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Securityholders; provided that any such notice
may state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

SECTION 2.12     Right of Set Off.
                 ----------------

         Notwithstanding anything to the contrary in this Indenture, the Company
shall have the right to set off any payment it is otherwise required to make
hereunder to the extent the Company has theretofore made, or is concurrently on
the date of such payment making, a payment under the Preferred Securities
Guarantee.

SECTION 2.13     Extension of Interest Payment Period.
                 ------------------------------------

         (a)  So long as no Event of Default has occurred and is continuing, the
Company shall have the right, at any time and from time to time during the term
of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding [10] consecutive
[semi-annual] periods (or the equivalent thereof), including the first such
[semi-annual] period during such extension period (the "Extended Interest
Payment Period"); provided that no Extended Interest Payment Period shall extend
beyond the Maturity Date. To the extent permitted by applicable law, interest,
the payment of which has been deferred because of the extension of the interest
payment period pursuant to this Section 2.13(a), will bear interest thereon at
the Coupon Rate compounded [semi-annually] for each [semi-annual] period of the
Extended Interest Payment Period ("Compounded Interest"). At the end of the
Extended Interest Payment Period, the Company shall pay all interest accrued and
unpaid on the Securities, including any Additional Sums and Compounded Interest
(together, "Deferred Interest") that shall be payable to the holders of the
Securities in whose names the Securities are registered in the Security Register
on the first record date preceding the end of the Extended Interest Payment
Period. Before the termination of any Extended Interest Payment Period, the
Company may further defer payments of interest by further extending such period;
provided that such period, together with all such previous and further

                                       17

<PAGE>

extensions within such Extended Interest Payment Period, shall not exceed [10]
consecutive [semi annual] periods, including the first such [semi-annual] period
during such Extended Interest Payment Period or extend beyond the Maturity Date
of the Securities. Upon the termination of any Extended Interest Payment Period
and the payment of all Deferred Interest then due, the Company may commence a
new Extended Interest Payment Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof.

         (b) The Company shall give written notice to the Administrative
Trustees, the Property Trustee and the Trustee of its selection of such Extended
Interest Payment Period one Business Day before the earlier of (i) the next
succeeding date on which Distributions on the Trust Securities issued by the
Trust are payable, or (ii) the date the Trust is required to give notice of the
record date, or the date such Distributions are payable, to any national
securities exchange or to holders of the Preferred Securities issued by the
Trust, but in any event at least one Business Day before such record date.

         The [semi-annual] period in which any notice is given pursuant to
paragraphs (a) or (b) of this Section 2.13(b) shall be counted as one of the
[10][semi-annual] periods permitted in the maximum Extended Interest Payment
Period permitted under Section 2.13(a).

presented for payment, an office or agency where the Securities may be presented
for registration of transfer and for exchange as in this Indenture provided and
an office or agency where notices and demands to or upon the Company in respect
of the Securities or of this Indenture may be served. The Company will give to
the Trustee written notice of the location of any such office or agency and of
any change of location thereof. Until otherwise designated from time to time by
the Company in a notice to the Trustee, any such office or agency for all of the
above purposes shall be the Principal Office of the Trustee. In case the Company
shall fail to maintain any such office or agency in New York, New York, or shall
fail to give such notice of the location or of any change in the location

deliver to the Trustee an instrument in which such agent shall agree with the
Trustee, subject to the provision of this Section 3.04,

              (i)  that it will hold all sums held by it as such agent for the
payment of the principal of and premium, if any, or interest on the Securities

on the Securities) in trust for the benefit of the holders of the Securities and
comply with all provisions of the Trust Indenture Act applicable to it as paying
agent; and

              (ii) that it will give the Trustee notice of any failure by the
Company (or by any other obligor on the Securities) to make any payment of the
principal of and premium or interest (including Additional Sums and Compounded
Interest, if any) on the Securities when the same shall be due and payable.

         (b)  If the Company shall act as its own paying agent, it will, on or
before each due date of the principal of and premium, if any, or interest on the
Securities, set aside, segregate and hold in trust for the benefit of the
holders of the Securities a sum sufficient to pay such principal, premium or
interest so becoming due and will notify the Trustee of any failure to take such
action and of any failure by the Company (or by any other obligor under the
Securities) to make any payment of the principal of and premium, if any, or
interest on the Securities when the same shall become due and payable.

         (c)  Anything in this Section 3.04 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge with respect to the Securities hereunder, or for any other reason, pay

the Trustee or any paying agent hereunder, as required by this Section 3.04,
such sums to be held by the Trustee upon the trusts herein contained.

         (d)  Anything in this Section 3.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 3.04 is subject to
Sections 11.03 and 11.04.

         (e)  The Trustee will initially act as paying agent, Security Registrar
[and Conversion Agent]. The Company may change any such entity without prior
notice. The Company or its Affiliates may act in any of the foregoing
capacities.

                   REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT

SECTION 5.01   Events of Default.
               -----------------

         "Event of Default", wherever used herein with respect to Securities,
means any one of the following events (whatever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                                       23

<PAGE>

         (a)  default in the payment of any interest (including Compounded
Interest or Additional Sums, if any), upon any Security when it becomes due and
payable, and continuance of such default for a period of 30 days; provided,
however, that a valid extension of an interest payment period by the Company in
accordance with the terms hereof shall not constitute a default in the payment
of interest for this purpose; or

         (b)  default in the payment of all or any part of the principal of (or
premium, if any, on) any Security as and when the same shall become due and
payable either at maturity, upon redemption, by declaration of acceleration of
maturity or otherwise; or

         (c)  default in the performance, or breach, of any covenant or warranty
of the Company in this Indenture (other than a covenant or warranty a default in
whose performance or whose breach is elsewhere in this Section specifically
dealt with), and continuance of such default or breach for a period of 90 days
after there has been given, by registered or certified mail, to the Company by
the Trustee or to the Company and the Trustee by the holders of at least 25% in
aggregate principal amount of the outstanding Securities a written notice
specifying such default or breach and requiring it to be remedied and stating
that such notice is a "Notice of Default" hereunder; or

         (d)  a court having jurisdiction in the premises shall enter a decree
or order for relief in respect of the Company in an involuntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or appointing a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) of the Company or for any substantial part of
its property, or ordering the winding-up or liquidation of its affairs and such
decree or order shall remain unstayed and in effect for a period of 90
consecutive days; or

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

         (f)  the failure by the Company to deliver Common Stock upon an
election to convert the Securities into Common Stock.]

         If an Event of Default with respect to Securities at the time
outstanding occurs and is continuing, then in every such case the Trustee or the
holders of not less than 25% in aggregate principal amount of the Securities
then outstanding may declare the principal amount of all Securities to be due
and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the holders of the outstanding Securities), and upon any
such declaration the same shall become immediately due and payable. Payment of
principal and interest (including any Compounded Interest and Additional Sums to
the extent permitted by applicable law) on such Securities shall remain
subordinated to the extent provided in Article XII notwithstanding that such
amount shall become immediately due and payable as herein provided.

                                       24

<PAGE>

         The foregoing provisions, however, are subject to the condition that
if, at any time after the principal of the Securities shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, (i)
the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
(A) all matured installments of interest (including Compounded Interest and
Additional Sums, if any) upon all the Securities and the principal of and
premium, if any, on any and all Securities which shall have become due otherwise
than by acceleration (with interest upon such principal and premium, if any,
and, to the extent that payment of such interest is enforceable under applicable
law, on overdue installments of interest, at the same rate as the rate of
interest specified in the Securities to the date of such payment or deposit) and
(B) such amount as shall be sufficient to cover compensation due to the Trustee
and each predecessor Trustee, their respective agents, attorneys and counsel,
pursuant to Section 6.06, and (ii) any and all Events of Default under the
Indenture, other than the non-payment of the principal of the Securities which
shall have become due solely by such declaration of acceleration, shall have
been cured, waived or otherwise remedied as provided herein, then, in every such
case, the holders of a majority in aggregate principal amount of the Securities
then outstanding, by written notice to the Company and to the Trustee, may
rescind and annul such declaration and its consequences, but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent default
or shall impair any right consequent thereon.

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

SECTION 5.02   Payment of Securities on Default; Suit Therefor.
               -----------------------------------------------

         The Company covenants that (a) in case default shall be made in the
payment of any installment of interest (including Compounded Interest and
Additional Sums, if any) upon any of the Securities as and when the same shall
become due and payable, and such default shall have continued for a period of 30
days, or (b) in case default shall be made in the payment of the principal of or
premium, if any, on any of the Securities as and when the same shall have become
due and payable, whether at maturity of the Securities or upon redemption or by
declaration or otherwise, then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities, the whole
amount that then shall have become due and payable on all such Securities for
principal and premium, if any, or interest (including Compounded Interest and
Additional Sums, if any) or both, as the case may be, with interest upon the
overdue principal and premium, if any, and (to the extent that payment of such
interest is enforceable under applicable law and, if the Securities are held by
the Trust or a trustee of such trust, without duplication of any other amounts
paid by the Trust or a trustee in respect thereof) upon the overdue installments
of interest (including Compounded Interest and Additional Sums, if any) at the
rate borne by the Securities; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including a
reasonable compensation to the Trustee, its agents, attorneys and counsel, and
any other amount due to the Trustee pursuant to Section 6.06.

                                       25

<PAGE>

         In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the
Securities and collect in the manner provided by law out of the property of the
Company or any other obligor on the Securities wherever situated the moneys
adjudged or decreed to be payable.

         In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Securities under
Title 11, United States Code, or any other applicable law, or in case a receiver
or trustee shall have been appointed for the property of the Company or such
other obligor, or in the case of any other similar judicial proceedings relative
to the Company or other obligor upon the Securities, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 5.02,
shall be entitled and empowered, by intervention in such proceedings or
otherwise, to file and prove a claim or claims for the whole amount of principal
premium, if any, and interest (including Compounded Interest and Additional
Sums, if any) owing and unpaid in respect of the Securities and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for amounts due to the Trustee pursuant to 6.06) and of the
Securityholders allowed in such judicial proceedings relative to the Company or
any other obligor on the Securities, or to the creditors or property of the
Company or such other obligor, unless prohibited by applicable law and
regulations, to vote on behalf of the holders of the Securities in any election
of a trustee or a standby trustee in arrangement, reorganization, liquidation or
other bankruptcy or insolvency proceedings or person performing similar
functions in comparable proceedings, and to collect and receive any moneys or
other property payable or deliverable on any such claims, and to distribute the
same after the deduction of its charges and expenses; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Securityholders 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
Securityholders, to pay to the Trustee such amounts as shall be sufficient to
cover reasonable compensation to the Trustee, each predecessor Trustee and their
respective agents, attorneys and counsel, and all other amounts due to the
Trustee pursuant to Section 6.06.

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

         All rights of action and of asserting claims under this Indenture, or
under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities, or the production thereof on any trial or
other proceeding relative thereto, and any such suit or proceeding instituted by
the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment shall be for the ratable benefit of the holders of the
Securities.

                                       26

<PAGE>

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

SECTION 5.03     Application of Moneys Collected by Trustee.
                 ------------------------------------------

         Any moneys collected by the Trustee shall be applied in the following
order, at the date or dates fixed by the Trustee for the distribution of such
moneys, upon presentation of the Securities in respect of which moneys have been
collected, and stamping thereon the payment, if only partially paid, and upon
surrender thereof if fully paid:

         FIRST:  To the payment of costs and expenses of collection applicable
to the Securities and all other amounts due to the Trustee under Section 6.06;

         SECOND: To the payment of all Senior Indebtedness of the Company if and
to the extent required by Article XII;

         THIRD:  To the payment of the amounts then due and unpaid upon
Securities for principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) on the Securities, in respect
of which or for the benefit of which money has been collected, ratably, without
preference of priority of any kind, according to the amounts due on such
Securities for principal (and premium, if any) and interest, respectively; and

         FOURTH: To the Company.

SECTION 5.04     Proceedings by Securityholders.
                 ------------------------------

         No holder of any Security shall have any right by virtue of or by
availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof with respect to the
Securities specifying such Event of Default, as hereinbefore provided, and
unless also the holders of not less than 25% in aggregate principal amount of
the Securities then outstanding shall have made written request upon the Trustee
to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein
or thereby, and the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such action,
suit or proceeding, it being understood and intended, and being expressly
covenanted by the taker and holder of every Security with every other taker and
holder and the Trustee, that no one or more holders of Securities shall have any
right in any manner whatever by virtue of or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of any other holder of
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities.

                                       27

<PAGE>

         Notwithstanding any other provisions in this Indenture, however, the
right of any holder of any Security, which right is absolute and unconditional,
to receive payment of the principal of (premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) on such Security, on or after
the same shall have become due and payable, or to institute suit for the
enforcement of any such payment, shall not be impaired or affected without the
consent of such holder and by accepting a Security hereunder it is expressly
understood, intended and covenanted by the taker and holder of every Security
with every other such taker and holder and the Trustee, that no one or more
holders of Securities shall have any right in any manner whatsoever by virtue or
by availing of any provision of this Indenture to affect, disturb or prejudice
the rights of the holders of any other Securities, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Securities. For the
protection and enforcement of the provisions of this Section, each and every
Securityholder and the Trustee shall be entitled to such relief as can be given
either at law or in equity.


         If an Event of Default has occurred and is continuing and such event is
attributable to the failure of the Company to pay principal of or premium, if
any, or interest on the Securities when due, the Company acknowledges that a
holder of Preferred Securities may directly institute a proceeding for
enforcement of payment to such holder of the principal of or premium, if any, or
interest on the Securities having a principal amount equal to the aggregate
liquidation amount of the Preferred Securities of such holder on or after the
respective due date specified in the Securities.

SECTION 5.05  Proceedings by Trustee.
              ----------------------

         In case an Event of Default occurs with respect to Securities and is
continuing, the Trustee may in its discretion proceed to protect and enforce the
rights vested in it by this Indenture by such appropriate judicial proceedings
as the Trustee shall deem most effectual to protect and enforce any of such
rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

SECTION 5.06  Remedies Cumulative and Continuing.
              ----------------------------------

         All powers and remedies given by this Article V to the Trustee or to
the Securityholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any other powers and remedies available to the Trustee or
the holders of the Securities, by judicial proceedings or otherwise, to enforce
the performance or observance of the covenants and agreements contained in this
Indenture or otherwise established with respect to the Securities, and no delay
or omission of the Trustee or of any holder of any of the Securities to exercise
any right or power accruing upon any

                                       28

<PAGE>

Event of Default occurring and continuing as aforesaid shall impair any such
right or power, or shall be construed to be a waiver of any such default or an
acquiescence therein; and, subject to the provisions of Section 5.04, every
power and remedy given by this Article V or by law to the Trustee or to the
Securityholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Securityholders.

SECTION 5.07   Direction of Proceedings and Waiver of Defaults by Majority of
               --------------------------------------------------------------
Securityholders.
---------------

         The holders of a majority in aggregate principal amount of the
Securities at the time outstanding shall have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee; provided,
however, that such direction shall not be in conflict with any rule or law or
with this Indenture and, (subject to the provisions of Section 6.01) the Trustee
shall have the right to decline to follow any such direction if the Trustee
shall determine that the action so directed would be unjustly prejudicial to the
holders not taking part in such direction or if the Trustee being advised by
counsel determines that the action or proceeding so directed may not lawfully be
taken or if the Trustee in good faith by its board of directors or trustees,
executive committee, or a trust committee of directors or trustees and/or
Responsible Officers shall determine that the action or proceedings so directed
would involve the Trustee in personal liability.

         Prior to any declaration accelerating the maturity of the Securities,
the holders of a majority in aggregate principal amount of the Securities at the
time outstanding may on behalf of the holders of all of the Securities waive any
past default or Event of Default and its consequences except (a) a continuing
default in the payment of principal of or premium, if any, or interest
(including Compounded Interest and Additional Sums, if any) on any of the
Securities or (b) a default in respect of covenants or provisions hereof which
cannot be modified or amended without the consent of the holder of each Security
(or Preferred Security) affected. Upon any such waiver, the default covered
thereby shall be deemed to be cured for all purposes of this Indenture and the
Company, the Trustee and the holders of the Securities shall be restored to
their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other default or impair any right consequent
thereon. Whenever any default or Event of Default hereunder shall have been
waived as permitted by this Section 5.07, said default or Event of Default shall
for all purposes of the Securities and this Indenture be deemed to have been
cured and to be not continuing.


SECTION 5.08   Notice of Defaults.
               ------------------

         (a) The Trustee shall, within 90 days after the occurrence of a default
with respect to the Securities known to a Responsible Officer of the Trustee,
mail to all Securityholders, as the names and addresses of such holders appear
upon the Security Register, notice of all defaults known to the Trustee, unless
such defaults shall have been cured before the giving of such notice (the term
"defaults" for the purpose of this Section 5.08 being hereby defined to be the
events specified in clauses (a), (b), (c), (d) and (e) of Section 5.01, not
including periods of grace, if any, provided for therein, and irrespective of
the giving of written notice specified in clause (c) of Section 5.01); and
provided that, except in the case of default in the payment of the principal of
or premium, if any, or interest (including Compounded Interest or Additional
Sums, if any) on any of the Securities, the

                                       29

<PAGE>

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 interests of the Securityholders; and
provided further, that in the case of any default of the character specified in
Section 5.01(c) no such notice to Securityholders shall be given until at least
60 days after the occurrence thereof but shall be given within 90 days after
such occurrence.

        (b) Within five Business Days after the occurrence of any Event of
Default actually known to the Trustee, the Trustee shall transmit notice of such
Event of Default to all Securityholders, unless such Event of Default shall have
been cured or waived.

SECTION 5.09   Undertaking to Pay Costs.
               ------------------------

        All parties to this Indenture agree, and each holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, 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 5.09 shall not apply to any suit instituted by
the Company or the Trustee; to any suit instituted by any Securityholder, or
group of Securityholders, holding in the aggregate more than 25% in aggregate
principal amount of the Securities outstanding; or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest (including Compounded Interest and Additional Sums,
if any) on any Security against the Company on or after the same shall have
become due and payable.

SECTION 5.10   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.

                                   ARTICLE VI
                             CONCERNING THE TRUSTEE

SECTION 6.01   Duties and Responsibilities of Trustee.
               --------------------------------------

        With respect to the holders of the Securities issued hereunder, the
Trustee, prior to the occurrence of an Event of Default and after the curing or
waiving of all Events of Default which may have occurred, undertakes to perform
such duties and only such duties as are specifically set forth in this
Indenture. In case an Event of Default has occurred (which has not been cured or
waived) the

                                       30

<PAGE>

Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

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

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

             (ii) in the absence of bad faith on the part of the Trustee, the
Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon any certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture;
but, in the case of any such certificates or opinions which by any 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;

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

        (c)  the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith, in accordance with the direction of the
Securityholders pursuant to Section 5.07, 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.

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

SECTION 6.02   Reliance on Documents, Opinions, etc.
               ------------------------------------

        Except as otherwise provided in Section 6.01:

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

                                       31

<PAGE>

        (b) prior to acting or refraining from acting, the Trustee may require
an Officers' Certificate or Opinion of Counsel to be furnished by, or on behalf
of, the Company;

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

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

        (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, order or
direction of any of the Securityholders, pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
reasonable and sufficient security or indemnity against the costs, expenses and
liabilities which may be incurred therein or thereby;

        (f) the Trustee shall not be liable for any action taken 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;

        (g) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, debenture,
coupon or other paper or document;

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

        (i) the Trustee shall not be charged with knowledge of any Default or
Event of Default with respect to the Securities unless a Responsible Officer
shall have actual knowledge of such Default or Event of Default or written
notice of such Default or Event of Default shall have been given to the Trustee
by the Company or any other obligor on the Securities or by any holder of the
Securities; and

        (j) the Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith, without negligence or willful misconduct and
believed by it to be authorized or within the discretion or rights or powers
conferred upon it by this Indenture.

SECTION 6.03    No Responsibility for Recitals, etc.
                -----------------------------------

        The recitals contained herein and in the Securities (except in the
certificate of authentication of the Trustee or the Authenticating Agent) shall
be taken as the statements of the Company and the Trustee and the Authenticating
Agent assume no responsibility for the correctness of the same. The

                                       32

<PAGE>

Trustee and the Authenticating Agent make no representations as to the validity
or sufficiency of this Indenture or of the Securities. The Trustee and the
Authenticating Agent shall not be accountable for the use or application by the
Company of any Securities or the proceeds of any Securities authenticated and
delivered by the Trustee or the Authenticating Agent in conformity with the
provisions of this Indenture.

SECTION 6.04      Trustee, Authenticating Agent, Paying Agents, Transfer Agents
                  -------------------------------------------------------------
or Registrar May Own Securities.
-------------------------------

        The Trustee or any Authenticating Agent or any paying agent or any
transfer agent or any Security Registrar, in its individual or any other
capacity, may become the owner or pledgee of Securities with the same rights it
would have if it were not Trustee, Authenticating Agent, paying agent, transfer
agent or Security Registrar.

SECTION 6.05      Moneys to be Held in Trust.
                  --------------------------

        Subject to the provisions of Section 11.04, all moneys received by the
Trustee or any paying agent shall, until used or applied as herein provided, be
held in trust for the purpose for which they were received, but need not be
segregated from other funds except to the extent required by law. The Trustee
and any paying agent shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the Company.
So long as no Event of Default shall have occurred and be continuing, all
interest allowed on any such moneys shall be paid from time to time upon the
written order of the Company, signed by the Chairman of the Board of Directors,
the President, a Vice President, the Treasurer or an Assistant Treasurer of the
Company.

SECTION 6.06      Compensation and Expenses of Trustee.
                  ------------------------------------

        The Company, as issuer of Securities under this Indenture, covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as shall be agreed to in writing between the
Company and the Trustee (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust), and the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith. The Company also covenants to indemnify
each of the Trustee or any predecessor Trustee (and its officers, agents,
directors and employees) for, and to hold it harmless against, any and all loss,
damage, claim, liability or expense including taxes (other than taxes based on
the income of the Trustee) incurred without negligence or bad faith on the part
of the Trustee and 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 of liability in the premises. The obligations of the
Company under this Section 6.06 to compensate and indemnify the Trustee and to
pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder. Such additional indebtedness shall
be secured by a lien prior to that of the Securities upon all property and funds
held or collected by the Trustee as such, except funds held in trust for the
benefit of the holders of particular Securities.

                                       33

<PAGE>

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

        The provisions of this Section shall survive the resignation or removal
of the Trustee and the defeasance or other termination of this Indenture.

SECTION 6.07      Officers' Certificate as Evidence.
                  ---------------------------------

        Except as otherwise provided in Sections 6.01 and 6.02, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
omitting any action hereunder, such matter (unless other evidence in respect
thereof is herein specifically prescribed) may, in the absence of negligence or
bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officers' Certificate delivered to the Trustee, and such
certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken or omitted by
it under the provisions of this Indenture upon the faith thereof.

SECTION 6.08      Conflicting Interest of Trustee.
                  -------------------------------

        If the Trustee has or shall acquire any "conflicting interest" within
the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

SECTION 6.09      Eligibility of Trustee.
                  ----------------------

        The Trustee hereunder shall at all times be a corporation organized and
doing business under the laws of the United States of America or any state or
territory thereof or of the District of Columbia or a corporation or other
Person permitted to act as trustee by the Commission authorized under such laws
to exercise corporate trust powers, having a combined capital and surplus of at
least 50 million U.S. dollars ($50,000,000) and subject to supervision or
examination by federal, state, territorial, or District of Columbia authority.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 6.09 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.

        The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as
Trustee.

        In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 6.09, the Trustee shall resign immediately
in the manner and with the effect specified in Section 6.10.

                                       34

SECTION 6.10      Resignation or Removal of Trustee.
                  ---------------------------------

        (a) The Trustee, or any trustee or trustees hereafter appointed, may at
any time resign by giving written notice of such resignation to the Company and
by mailing notice thereof to the holders of the Securities at their addresses as
they shall appear on the Security register. Upon receiving such notice of
resignation, the Company shall promptly appoint a successor trustee or trustees
by written instrument, in duplicate, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee. If no
successor trustee shall have been so appointed and have accepted appointment
within 60 days after the mailing of such notice of resignation to the affected
Securityholders, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Securityholder
who has been a bona fide holder of a Security for at least six months may,
subject to the provisions of Section 5.09, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

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

            (i)   the Trustee shall fail to comply with the provisions of
Section 6.08 after written request therefor by the Company or by any
Securityholder who has been a bona fide holder of a Security or Securities for
at least six months, or

            (ii)  the Trustee shall cease to be eligible in accordance with the
provisions of Section 6.09 and shall fail to resign after written request
therefor by the Company or by any such Securityholder, or

            (iii) the Trustee shall become incapable of acting, or shall be
adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
property shall be appointed, or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, the Company may remove the
Trustee and appoint a successor trustee by written instrument, in duplicate, one
copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor trustee, or, subject to the provisions of Section 5.09,
any Securityholder who has been a bona fide holder of a Security for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor trustee. Such court may thereupon, after such notice,
if any, as it may deem proper, remove the Trustee and appoint a successor
trustee.

        (c) The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Trustee and
nominate a successor trustee, which shall be deemed appointed as successor
trustee unless within 10 days after such nomination the Company objects thereto
or if no successor trustee shall have been so appointed and shall have accepted
appointment within 30 days after such removal, in which case the Trustee so
removed or any Securityholder, upon the terms and conditions and otherwise as in
subsection (a) of this Section 6.10 provided, may petition any court of
competent jurisdiction for an appointment of a successor trustee.

                                       35

<PAGE>

         (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 6.10 shall
become effective only upon acceptance of appointment by the successor trustee as
provided in Section 6.11.

SECTION 6.11    Acceptance by Successor Trustee.
                -------------------------------

         Any successor trustee appointed as provided in Section 6.10 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the retiring trustee shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor trustee,
the trustee ceasing to act shall, upon payment of any amounts then due it
pursuant to the provisions of Section 6.06, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee
so ceasing to act and shall duly assign, transfer and deliver to such successor
trustee all property and money held by such retiring trustee thereunder. Upon
request of any such successor trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.06.

         No successor trustee shall accept appointment as provided in this
Section 6.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 6.08 and eligible under the
provisions of Section 6.09.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 6.11, the Company shall mail notice of the succession of such
trustee hereunder to the holders of Securities at their addresses as they shall
appear on the Security register. If the Company fails to mail such notice within
10 days after the acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the
Company.

SECTION 6.12    Succession by Merger, etc.
                -------------------------

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder without
the execution or filing of any paper or any further act on the part of any of
the parties hereto provided such corporations shall be otherwise qualified and
eligible under this Article.

         In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any Securities shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any

                                       36

<PAGE>

predecessor hereunder or in the name of the successor trustee; and in all such
cases such certificates shall have the full force which the Securities or this
Indenture elsewhere provides that the certificate of the Trustee shall have;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

SECTION 6.13    Limitation on Rights of Trustee as a Creditor.
                ---------------------------------------------

         The Trustee shall comply with Section 311(a) of the Trust Indenture
Act. A Trustee who has resigned or been removed shall be subject to Section
311(a) of the Trust Indenture Act to the extent included therein.

SECTION 6.14    Authenticating Agents.
                ---------------------

         There may be one or more Authenticating Agents appointed by the Trustee
upon the request of the Company with power to act on its behalf and subject to
its direction in the authentication and delivery of Securities issued upon
exchange or transfer thereof as fully to all intents and purposes as though any
such Authenticating Agent had been expressly authorized to authenticate and
deliver Securities; provided, that the Trustee shall have no liability to the
Company for any acts or omissions of the Authenticating Agent with respect to
the authentication and delivery of Securities. Any such Authenticating Agent
shall at all times be a corporation organized and doing business under the laws
of the United States or of any state or territory thereof or of the District of
Columbia authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of at least $50,000,000 and being subject to
supervision or examination by federal, state, territorial or District of
Columbia authority. If such corporation publishes reports of condition at least
annually pursuant to law or the requirements of such authority, then for the
purposes of this Section 6.14 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 an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect herein specified in this Section.

         Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 6.14 without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authenticating Agent.

         Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible under this Section 6.14, the
Trustee may, and upon the request of the Company shall, promptly appoint a
successor Authenticating Agent eligible under this Section 6.14, shall give
written notice of such appointment to the Company and

                                       37

<PAGE>

shall mail notice of such appointment to all Securityholders as the names and
addresses of such holders appear on the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent
herein.

         The Company, as borrower, agrees to pay to any Authenticating Agent
from time to time reasonable compensation for its services. Any Authenticating
Agent shall have no responsibility or liability for any action taken by it as
such in accordance with the directions of the Trustee.

                                  ARTICLE VII
                         CONCERNING THE SECURITYHOLDERS

SECTION 7.01    Action by Securityholders.
                -------------------------

         Whenever in this Indenture it is provided that the holders of a
specified percentage in aggregate principal amount of the Securities may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action) the fact that at
the time of taking any such action the holders of such specified percentage have
joined therein may be evidenced by any instrument or any number of instruments
of similar tenor executed by such Securityholders in person or by agent or proxy
appointed in writing.

         If the Company shall solicit from the Securityholders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Company may, at its option, as evidenced by an Officers' Certificate, fix in
advance a record date for the determination of Securityholders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other
action, but the Company shall have no obligation to do so. If such a record date
is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other action may be given before or after the record date, but only
the Securityholders of record at the close of business on the record date shall
be deemed to be Securityholders for the purposes of determining whether
Securityholders of the requisite proportion of outstanding Securities have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other action, and for that purpose the
outstanding Securities shall be computed as of the record date; provided,
however, that no such authorization, agreement or consent by such
Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

SECTION 7.02    Proof of Execution by Securityholders.
                -------------------------------------

         Subject to the provisions of Section 6.01 and 6.02, proof of the
execution of any instrument by a Securityholder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Trustee or in such manner as shall be satisfactory to
the Trustee. The ownership of Securities shall be proved by the Security
Register or by a certificate of the Security Registrar. The Trustee may require
such additional proof of any matter referred to in this Section as it shall deem
necessary.

                                       38

<PAGE>

SECTION 7.03    Who Are Deemed Absolute Owners.
                ------------------------------

         Prior to due presentment for registration of transfer of any Security,
the Company, the Trustee, any Authenticating Agent, any paying agent, any
transfer agent and any Security Registrar may deem the person in whose name such
Security shall be registered upon the Security Register to be, and may treat him
as, the absolute owner of such Security (whether or not such Security shall be
overdue) for the purpose of receiving payment of or on account of the principal
of and premium, if any, and (subject to Section 2.05) interest on such Security
and for all other purposes; and neither the Company nor the Trustee nor any
Authenticating Agent nor any paying agent nor any transfer agent nor any
Security Registrar shall be affected by any notice to the contrary. All such
payments so made to any holder for the time being or upon his order shall be
valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for moneys payable upon any such Security.

SECTION 7.04    Securities Owned by Company Deemed Not Outstanding.
                --------------------------------------------------

         In determining whether the holders of the requisite aggregate principal
amount of Securities have concurred in any direction, consent, notice or waiver
under this Indenture, Securities which are owned by the Company or any other
obligor on the Securities or any Affiliate of the Company (other than the Trust)
or any other obligor on the Securities shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, consent or waiver, only Securities which a Responsible Officer
of the Trustee actually knows are so owned shall be so disregarded. Securities
so owned which have been pledged in good faith may be regarded as outstanding
for the purposes of this Section 7.04 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee's right to vote such Securities and that
the pledgee is not the Company or any such other obligor or Affiliate of the
Company or any such other obligor. In the case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee.

SECTION 7.05    Revocation of Consents; Future Holders Bound.
                --------------------------------------------

         At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 7.01, of the taking of any action by the holders of the
percentage in aggregate principal amount of the Securities specified in this
Indenture in connection with such action, any holder of a Security (or any
Security issued in whole or in part in exchange or substitution therefor),
subject to Section 7.01, the serial number of which is shown by the evidence to
be included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee at its principal office and upon
proof of holding as provided in Section 7.02, revoke such action so far as
concerns such Security (or so far as concerns the principal amount represented
by any exchanged or substituted Security). Except as aforesaid any such action
taken by the holder of any Security shall be conclusive and binding upon such
holder and upon all future holders and owners of such Security, and of any
Security issued in exchange or substitution therefor, irrespective of whether or
not any notation in regard thereto is made upon such Security or any Security
issued in exchange or substitution therefor.

as the case may be, shall be a party or parties, or shall prevent any sale,
conveyance, transfer or lease of the property of the Company, or its successor
or successors as the case may be, as an entirety, or substantially as an
entirety, to any other Person (whether or not affiliated with the Company, or
its successor or successors, as the case may be) authorized to acquire and
operate the same; provided, that (a) the Company is the surviving Person, or the
Person formed by or surviving any such consolidation or merger (if other than
the Company) or to which such sale, conveyance, transfer or lease of property is
made is a Person organized and existing under the laws of the United States or
any State thereof or the District of Columbia, and (b) upon any such
consolidation, merger, sale, conveyance, transfer or lease, the due and punctual
payment of the principal of (and premium, if any) and interest on the Securities
according to their tenor and the due and punctual performance and observance of
all the covenants and conditions of this Indenture to be kept or performed by
the Company shall be expressly assumed, by supplemental indenture (which shall
conform to the provisions of the Trust Indenture Act, as then in effect)
satisfactory in form to the Trustee executed and delivered to the Trustee by the
Person formed by such consolidation, or into which the Company shall have been
merged, or by the Person which shall have acquired such property, as the case

the Company, such successor Person shall succeed to and be substituted for the
Company, with the same effect as if it had been named herein as the party of the
first part, and the Company thereupon shall be relieved of any further liability
or obligation hereunder or upon the Securities. Such successor Person thereupon
may cause to be signed, and may issue either in its own name or in the name of
Spinnaker Exploration Company any or all of the Securities issuable hereunder
which theretofore shall not have been signed by the Company and delivered to the
Trustee or the Authenticating Agent; and, upon the order of such successor
Person instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee or the Authenticating
Agent shall authenticate and deliver any Securities which previously shall have
been signed and delivered by the officers of the Company to the Trustee or the
Authenticating Agent for authentication, and any Securities which such successor
Person thereafter shall cause to be signed and delivered to the Trustee or the

                                       40

Authenticating Agent for that purpose. All the Securities so issued shall in all
respects have the same legal rank and benefit under this Indenture as the
Securities theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Indentures had been issued at the date of the
execution hereof.

SECTION 9.01  Without Consent of Securityholders.
              ----------------------------------

     The Company, when authorized by a Board Resolution, and the Trustee may
from time to time and at any time enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, without the consent of the
Securityholders, for one or more of the following purposes:

     (a) to evidence the succession of another Person to the Company, or
successive successions, and the assumption by the successor Person of the
covenants, agreements and obligations of the Company herein and in the
Securities pursuant to Article VIII hereof;

     (b) to add to the covenants of the Company such further covenants,
restrictions or conditions for the protection of the Securityholders as the
Board of Directors and the Trustee shall consider to be for the protection of
the Securityholders, and to make the occurrence, or the occurrence and
continuance, of a default in any of such additional covenants, restrictions or
conditions a default or an Event of Default permitting the enforcement of all or
any of the remedies provided in this Indenture as herein set forth; provided,
however, that in respect of any such additional covenant, restriction or
condition such amendment may provide for a particular period of grace after

other defaults) or may provide for an immediate enforcement upon such default or
may limit the remedies available to the Trustee upon such default;

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

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

                                       41

<PAGE>

     (g) to qualify or maintain qualification of this Indenture under the Trust

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

     Any amendment to the Indenture authorized by the provisions of this Section
9.01 may be executed by the Company and the Trustee without the consent of the
holders of any of the Securities at the time outstanding, notwithstanding any of
the provisions of Section 9.02.

SECTION 9.02  With Consent of Securityholders.
              -------------------------------

     With the consent (evidenced as provided in Section 7.01) of the holders of
a majority in aggregate principal amount of the Securities at the time
outstanding, the Company, when authorized by a Board Resolution, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of
modifying in any manner the rights of the holders of the Securities; provided,
however, that no such amendment shall without the consent of the holders of each
Security then outstanding and affected thereby (i) change the Maturity Date of

thereon, if any, or reduce any amount payable on redemption thereof, or make the
principal thereof or any interest or premium thereon payable in any coin or
currency other than that provided in the Securities, or impair or affect the
right of any Securityholder to institute suit for payment thereof [or adversely
affect the right to convert such Security as provided in Article XIII], (ii)
modify the provisions of this Indenture with respect to the subordination of the
Securities in a manner adverse to the holders of Securities, (iii) reduce the
aforesaid percentage of Securities the holders of which are required to consent
to any such amendment to the Indenture, or the consent of whose holders is
required for any waiver (of compliance with certain provisions of this Indenture
or certain defaults hereunder and their

                                       42

<PAGE>

consequences) provided for in this Indenture or (iv) modify any of the
provisions of the first paragraph of this Section 9.02, or the second sentence
of Section 5.07, except to increase any such percentage or to provide that
certain other provisions of this Indenture cannot be modified or waived without
the consent of the holder of each outstanding Security affected thereby;
provided, however, that if the Securities are held by the Trust, such amendment
shall not be effective until the holders of a majority in liquidation amount of
Trust Securities shall have consented to such amendment; provided, further, that
if the consent of the holder of each outstanding Security is required, such
amendment shall not be effective until each holder of the Trust Securities shall
have consented to such amendment.

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

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall transmit by mail, first class postage prepaid, a notice, prepared by the
Company, setting forth in general terms the substance of such supplemental
indenture, to the Securityholders as their names and addresses appear upon the
Security Register. Any failure of the Trustee to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

         It shall not be necessary for the consent of the Securityholders under
this Section 9.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

part of the terms and conditions of this Indenture for any and all purposes.

SECTION 9.04 Notation on Securities.
             ----------------------

         Securities authenticated and delivered after the execution of any
supplemental indenture affecting such series pursuant to the provisions of this

                                       43

Company or the Trustee shall so determine, new Securities so modified as to

                                   REDEMPTION

SECTION 10.01 Special Event Redemption.
              ------------------------

         [If, at any time, a Special Event has occurred and is continuing then,
notwithstanding Section 10.02(a), the Company shall have the right but not the
obligation, at any time within 90 days following the occurrence of such Special
Event, upon (i) not less than 45 days' written notice to the Trustee and (ii)
not less than 30 days' nor more than 60 days' written notice to the
Securityholders, to redeem the Securities, in whole (but not in part), at the
Special Event Redemption Price. Following a Special Event, if the Company wishes
to exercise its right of redemption pursuant to this Section 10.01, the Company
shall take such action as is necessary to promptly determine the Special Event
Redemption Price, including ______________. The Company shall provide the
Trustee with written notice of the Special Event Redemption Price promptly after
the calculation thereof, which notice shall include _________________. The
Special Event Redemption Price shall be paid prior to 12:00 noon, New York City
time, on the date of such redemption or such earlier time as the Company
determines, provided that the Company shall deposit with the Trustee an amount
sufficient to pay the Special Event Redemption Price by 10:00 a.m., New York
City time, on the date such Special Event Redemption Price is to be paid.]

SECTION 10.02 Optional Redemption by Company.
              ------------------------------

         [Subject to the provisions of this Article X, the Company shall have
the right to redeem the Securities, in whole or in part, from time to time, at a
redemption price equal to the Optional Redemption Price.

         If the Securities are only partially redeemed pursuant to this Section
10.02, the Securities to be redeemed shall be selected on a pro rata basis not
more than 60 days prior to the date fixed for redemption from the outstanding
Securities not previously called for redemption; provided that any such
proration may be made on the basis of the aggregate principal amount of
Securities held by each Securityholder and may be made by making such
adjustments as the Company deems fair and appropriate in order that only
Securities in denominations of [$1,000] or integral multiples thereof shall be
redeemed. The Optional Redemption Price shall be paid prior to 12:00 noon, New
York City time, on the date of such redemption or at such earlier time as the
Company determines;

                                       44

<PAGE>

provided that the Company shall deposit with the Trustee an amount sufficient to
pay the Optional Redemption Price by 10:00 a.m., New York City time, on the date
such Optional Redemption Price is to be paid.]

SECTION 10.03 No Sinking Fund.
              ---------------

         The Securities are not entitled to the benefit of any sinking fund.

SECTION 10.04 Notice of Redemption; Selection of Securities.
              ---------------------------------------------

         In case the Company shall desire to exercise the right to redeem all,
or, as the case may be, any part of the Securities in accordance with their
terms, it shall fix a date for redemption and shall mail a notice of such
redemption at least 30 and not more than 60 days prior to the date fixed for
redemption to the holders of Securities so to be redeemed as a whole or in part
at their last addresses as the same appear on the Security Register. Such
mailing shall be by first class mail. The notice if mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives such notice. In any case, failure to give such notice by
mail or any defect in the notice to the holder of any Security designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security.

         Each such notice of redemption shall specify the CUSIP number of the
Securities to be redeemed, the date fixed for redemption, the redemption price
at which the Securities are to be redeemed (or the method by which such
redemption price is to be calculated), the place or places of payment that
payment will be made upon presentation and surrender of the Securities, that
interest accrued to the date fixed for redemption will be paid as specified in
said notice, [the date on which the right to convert the Securities to be
redeemed will terminate and the places where such Securities may be surrendered
for conversion,] and that on and after said date interest thereon or on the
portions thereof to be redeemed will cease to accrue. If less than all the
Securities are to be redeemed the notice of redemption shall specify the numbers
of the Securities to be redeemed. In case any Security is to be redeemed in part
only, the notice of redemption shall state the portion of the principal amount
thereof to be redeemed and shall state that on and after the date fixed for
redemption, upon surrender of such Security, a new Security or Securities in
principal amount equal to the unredeemed portion thereof will be issued.

         The Company will give the Trustee notice not less than 45 days prior to
the redemption date as to the aggregate principal amount of Securities to be
redeemed and the Trustee shall select, in such manner as in its sole discretion
it shall deem appropriate and fair, the Securities or portions thereof (in
integral multiples of [$1,000], except as otherwise set forth in the applicable
form of Security) to be redeemed.

SECTION 10.05 Payment of Securities Called for Redemption.
              -------------------------------------------

         By 12:00 noon New York City time on the redemption date specified in
the notice of redemption given as provided in this Section, the Company will
deposit with the Trustee or with one or more paying agents an amount of money
sufficient to redeem on the redemption date all the

                                       45

<PAGE>

Securities so called for redemption at the appropriate Redemption Price,
together with accrued interest to the date fixed for redemption.

         [If any Security called for redemption is converted, any money
deposited with the Trustee or with any paying agent or so segregated and held in
trust for the redemption of such Security shall be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.]

         If notice of redemption has been given as provided in Section 10.04,
the Securities or portions of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the applicable Redemption Price, together with interest
accrued to the date fixed for redemption (subject to the rights of holders of
Securities on the close of business on a regular record date in respect of an
Interest Payment Date occurring on or prior to the redemption date), and on and
after said date (unless the Company shall default in the payment of such
Securities at the Redemption Price, together with interest accrued to said date)
interest (including Compounded Interest and Additional Sums, if any) on the
Securities or portions of Securities so called for redemption shall cease to
accrue. On presentation and surrender of such Securities at a place of payment
specified in said notice, the said Securities or the specified portions thereof
shall be paid and redeemed by the Company at the applicable Redemption Price,
together with interest (including Compounded Interest and Additional Sums, if
any) accrued thereon to the date fixed for redemption (subject to the rights of
holders of Securities on the close of business on a regular record date in
respect of an Interest Payment Date occurring on or prior to the redemption
date).

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to the holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

been destroyed, lost or stolen and which shall have been replaced as provided in
Section 2.07) and not theretofore canceled, or (b) all the Securities not
theretofore canceled or delivered to the Trustee for cancellation shall have
become due and payable, or are by their terms to become due and payable within

satisfactory to the Trustee for the giving of notice of redemption, and the
Company shall deposit with the Trustee, in trust, funds sufficient to pay on the
Maturity Date or upon redemption all of the Securities (other than any
Securities which shall have been destroyed, lost or stolen and which shall have
been replaced as provided in Section 2.07) not theretofore canceled or delivered
to the Trustee for cancellation, including principal and premium, if any, and
interest (including Compounded Interest and Additional Sums, if any) due or to
become due to the Maturity Date or redemption date, as the case may be, but
excluding, however, the amount of

<PAGE>

any moneys for the payment of principal of or premium, if any, or interest

Section 11.04, or (2) paid to any State or to the District of Columbia pursuant
to its unclaimed property or similar laws, and if in either case the Company
shall also pay or cause to be paid all other sums payable hereunder by the
Company, then this Indenture shall cease to be of further effect except for the
provisions of Sections 2.02, 2.06, 2.07, 6.10, 11.04 [and Article XIII] hereof,
which shall survive until such Securities shall mature and be paid [or are
converted]. Thereafter, Sections 6.10 and 11.04 shall survive, and the Trustee,
on demand of the Company accompanied by any Officers' Certificate and an Opinion
of Counsel and at the cost and expense of the Company, shall execute proper
instruments acknowledging satisfaction of and discharging this Indenture, the
Company, however, hereby agreeing to reimburse the Trustee for any costs or
expenses thereafter reasonably and properly incurred by the Trustee in
connection with this Indenture or the Securities.

to the payment, either directly or through any paying agent (including the
Company if acting as its own paying agent), to the holders of the particular
Securities for the payment of which such moneys have been deposited with the
Trustee, of all sums due and to become due thereon for principal, premium, if
any, and interest.

SECTION 11.03   Paying Agent to Repay Moneys Held.
                ---------------------------------

         Upon the satisfaction and discharge of this Indenture all moneys then

written demand of the Company, be repaid to it or paid to the Trustee, and
thereupon such paying agent shall be released from all further liability with
respect to such moneys.

SECTION 11.04   Return of Unclaimed Moneys.

         Any moneys deposited with or paid to the Trustee or any paying agent
for payment of the principal of or premium, if any, or interest on Securities
and not applied but remaining unclaimed by the holders of Securities for two
years after the date upon which the principal of or premium, if any, or interest
(including Compounded Interest and Additional Sums, if any) on such Securities,
as the case may be, shall have become due and payable, shall be repaid to the
Company by the Trustee or such paying agent on written demand; and the holder of
any of the Securities shall thereafter look only to the Company for any payment
which such holder may be entitled to collect and all liability of the Trustee or
such paying agent with respect to such moneys shall thereupon cease. [All moneys
deposited with the Trustee pursuant to Section 11.01 (and held by it or any
paying agent) for the payment of Securities subsequently converted shall be
returned to the Company upon Company Request.]

interest (including Compounded Interest and Additional Sums, if any) on all
Securities issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated and junior in right of payment to all Senior
Indebtedness, whether outstanding at the date of this Indenture or thereafter
incurred.

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

SECTION 12.02   Default on Senior Indebtedness.
                ------------------------------

         In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness, or in the event that the maturity of any Senior
Indebtedness has been accelerated because of a default, then, in either case, no
payment shall be made by the Company with respect to the principal (including
redemption payments) of or premium, if any, or interest on the Securities until
such default shall have been cured or waived in writing or shall have ceased to
exist or such Senior Indebtedness shall have been discharged or paid in full.

         In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee or any Securityholder when such payment is prohibited by
the preceding paragraphs of this Section 12.02, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Indebtedness
may have been issued, as their respective interests may appear.

SECTION 12.03   Liquidation; Dissolution; Bankruptcy.
                ------------------------------------

         Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all Senior Indebtedness of the Company shall
first be paid in full, or payment thereof provided for in money in accordance
with its terms, before any payment is made by the Company on account of the
principal (and premium, if any) or interest (including Compounded Interest and
Additional Sums, if any) on the Securities; and upon any such dissolution or
winding-up or liquidation or reorganization, any payment by the Company, or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Securityholders or the Trustee would be
entitled to receive from the Company, except for the provisions of this Article
XII, shall be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or

                                       48

distribution, or by the Securityholders or by the Trustee under the Indenture if
received by them or it, directly to the holders of Senior Indebtedness of the
Company (pro rata to such holders on the basis of the respective amounts of
Senior Indebtedness held by such holders, as calculated by the Company) or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent
necessary to pay all such Senior Indebtedness in full, in money in accordance
with its terms, after giving effect to any concurrent payment or distribution to
or for the holders of such Senior Indebtedness, before any payment or
distribution is made to the Securityholders or to the Trustee.

         In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee or any Securityholder before all Senior Indebtedness is paid in full, or
provision is made for such payment in money in accordance with its terms, such
payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of such Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Senior Indebtedness
may have been issued, as their respective interests may appear, as calculated by
the Company, for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all such Senior Indebtedness in full in
money in accordance with its terms, after giving effect to any concurrent
payment or distribution to or for the benefit of the holders of such Senior
Indebtedness.

         For purposes of this Article XII only, the words "assets of the Company
of any kind or character, whether cash, property or securities" shall not be
deemed to include shares of stock of the Company as reorganized or readjusted,
or securities of the Company or any other corporation provided for by a plan of
reorganization or readjustment, the payment of which is subordinated at least to
the extent provided in this Article XII with respect to the Securities to the
payment of Senior Indebtedness that may at the time be outstanding; provided
that (i) such Senior Indebtedness is assumed by the new corporation, if any,
resulting from any such reorganization or readjustment, and (ii) the rights of
the holders of such Senior Indebtedness are not, without the consent of such
holders, altered by such reorganization or readjustment. The consolidation of

liquidation or dissolution of the Company following the sale, conveyance,
transfer or lease of its property as an entirety, or substantially as an
entirety, to another Person upon the terms and conditions provided for in
Article VIII of this Indenture shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 12.03 if such
other Person shall, as a part of such consolidation, merger, sale, conveyance,
transfer or lease, comply with the conditions stated in Article VIII of this
Indenture. Nothing in Section 12.02 or in this Section 12.03 shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 6.06 of this
Indenture.

         Nothing contained in this Article XII or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness of the Company, and the
holders of the Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the holders of the Securities the principal of (and
premium, if any) and interest (including Compounded Interest and Additional
Sums, if any) on the Securities as and when the same shall become due and
payable in accordance with their terms, or is

                                       49

<PAGE>

intended to or shall affect the relative rights of the holders of the Securities
and creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness of the Company, as the case may be, nor shall anything
herein or therein prevent the occurrence of an Event of Default under Article V
or prevent the Trustee or the holder of any Security from exercising all
remedies otherwise permitted by applicable law upon the occurrence of a Default
or an Event of Default under the Indenture, subject to the rights, if any, under
this Article XII of the holders of such Senior Indebtedness in respect of cash,
property or securities of the Company, as the case may be, received upon the
exercise of any such remedy.

SECTION 12.04   Subrogation.
                -----------

         Subject to the payment in full of all Senior Indebtedness, the rights
of the Securityholders shall be subrogated to the rights of the holders of such
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company, as the case may be, applicable to such Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full; and, for the purposes of such subrogation, no
payments or distributions to the holders of such Senior Indebtedness of any
cash, property or securities to which the Securityholders or the Trustee would
be entitled except for the provisions of this Article XII, and no payment over
pursuant to the provisions of this Article XII to or for the benefit of the
holders of such Senior Indebtedness by Securityholders or the Trustee, shall, as
between the Company, its creditors other than holders of Senior Indebtedness of
the Company, and the holders of the Securities, be deemed to be a payment by the
Company to or on account of such Senior Indebtedness. It is understood that the
provisions of this Article XII are and are intended solely for the purposes of
defining the relative rights of the holders of the Securities, on the one hand,
and the holders of such Senior Indebtedness on the other hand.

SECTION 12.05   Trustee to Effectuate Subordination.
                -----------------------------------

         Each Securityholder by such Securityholder's acceptance thereof
authorizes and directs the Trustee on such Securityholder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article XII and appoints the Trustee such Securityholder's
attorney-in-fact for any and all such purposes.

SECTION 12.06   Notice by the Company.
                ---------------------

         The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company that would prohibit the making
of any payment of monies to or by the Trustee in respect of the Securities
pursuant to the provisions of this Article XII. Notwithstanding the provisions
of this Article XII or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts that would prohibit
the making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article XII, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
from the Company or a holder or holders of Senior Indebtedness or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Article VI of this Indenture, shall be
entitled in all respects to assume that no such facts exist; provided, however,
that if the Trustee shall not have received the notice provided for in this
Section 12.06 at least two


                                       50

<PAGE>

Business Days prior to the date upon which by the terms hereof any money may
become payable for any purpose (including, without limitation, the payment of
the principal of (or premium, if any) or interest (including Compounded Interest
and Additional Sums, if any) on any Security, then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purposes for which they were
received, and shall not be affected by any notice to the contrary that may be
received by it within two Business Days prior to such date.

         The Trustee, subject to the provisions of Article VI of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness of the
Company (or a trustee on behalf of such holder), as the case may be, to
establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee on behalf of any such holder or holders. In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of such Senior Indebtedness to
participate in any payment or distribution pursuant to this Article XII, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article XII, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

         Upon any payment or distribution of assets of the Company referred to
in this Article XII, the Trustee and the Securityholders shall be entitled to
rely upon any order or decree entered by any court of competent jurisdiction in
which such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian,
receiver, assignee for the benefit of creditors, agent or other person making
such payment or distribution, delivered to the Trustee or to the
Securityholders, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article XII.

SECTION 12.07   Rights of the Trustee; Holders of Senior Indebtedness.
                -----------------------------------------------------

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article XII in respect of any Senior Indebtedness at
any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article XII, and no implied
covenants or obligations with respect to the holders of such Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and,
subject to the provisions of Article VI of this Indenture, the Trustee shall not
be liable to any holder of such Senior Indebtedness

                                       51

<PAGE>

if it shall pay over or deliver to Securityholders, the Company or any other
Person money or assets to which any holder of such Senior Indebtedness shall be
entitled by virtue of this Article XII or otherwise.

         Nothing in this Article XII shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 6.06.

SECTION 12.08    Subordination May Not Be Impaired.
                 ---------------------------------

         No right of any present or future holder of any Senior Indebtedness of
the Company to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the
Company, as the case may be, or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company, as the case may be,
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness of the Company may, at any time and from time
to time, without the consent of or notice to the Trustee or the Securityholders,
without incurring responsibility to the Securityholders and without impairing or
releasing the subordination provided in this Article XII or the obligations
hereunder of the holders of the Securities to the holders of such Senior
Indebtedness, do any one or more of the following: (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, such
Senior Indebtedness, or otherwise amend or supplement in any manner such Senior
Indebtedness or any instrument evidencing the same or any agreement under which
such Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company, as the case may be, and any other
Person.

SECTION 12.09    Article Applicable to Paying Agents.
                 -----------------------------------

         In case at any time any paying agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such paying agent within
its meaning as fully for all intents and purposes as if such paying agent were
named in this Article in addition to or in place of the Trustee.

SECTION 12.10    Trust Moneys Not Subordinated.
                 -----------------------------

         Notwithstanding anything contained herein to the contrary, payments
from money held in trust under Section 11.02 of this Indenture by the Trustee
for the payment of principal of and interest on the Securities shall not be
subordinated to the prior payment of any Senior Indebtedness or subject to the
restrictions set forth in this Article XII, and none of the Securityholders
shall be obligated to pay over any such amount to the Company or any holder of
Senior Indebtedness of the Company or any other creditor of the Company.

                                  ARTICLE XIII
                            [CONVERSION OF SECURITIES

SECTION 13.01     Conversion Rights.
                  -----------------

         Subject to and upon compliance with the provisions of this Article, the
Securities are convertible, at the option of the holder, at any time prior to
5:00 p.m. New York City time on the Business Day immediately preceding
_____________ into [a number of fully paid and nonassessable shares of Common
Stock equal to the $____ principal amount per Security divided by the initial
conversion price of $___ (the "Initial Conversion Price") (equal to an initial
conversion ratio of approximately _____shares of Common Stock for each $___ in
aggregate principal amount of Securities).] The conversion price in effect at
any given time is known as the "Applicable Conversion Price" and is subject to
adjustment as described in this Article XIII. A holder of Securities may convert
any portion of the principal amount of the Securities into that number of fully
paid and nonassessable shares of Common Stock (calculated as to each conversion
to the nearest 1/100th of a share) obtained by dividing the principal amount of
the Securities to be converted by the Applicable Conversion Price. In case a
Security or portion thereof is called for redemption, such conversion right in
respect of the Security or portion so called shall expire at the close of the
Business Day immediately preceding the corresponding Redemption Date, unless the
Company defaults in making the payment due upon redemption.

SECTION 13.02     Conversion Procedures.
                  ---------------------

         (a) In order to convert all or a portion of the Securities, the holder
thereof shall deliver to the Conversion Agent an irrevocable Notice of
Conversion setting forth the principal amount of Securities to be converted,
together with the name or names, if other than the holder, in which the shares
of Common Stock should be issued upon conversion and, if such Securities are
definitive Securities, surrender to the Conversion Agent the Securities to be
converted, duly endorsed or assigned to the Company or in blank. In addition, a
holder of Preferred Securities may exercise its right under the Trust Agreement
to convert such Preferred Securities into Common Stock by delivering to the
Conversion Agent an irrevocable Notice of Conversion setting forth the
information called for by the preceding sentence and directing the Conversion
Agent (i) to exchange such Preferred Security for a portion of the Securities
held by the Trust (at an exchange rate of $____ principal amount of Securities
for each Preferred Security) and (ii) to immediately convert such Securities, on
behalf of such holder, into Common Stock of the Company pursuant to this Article
XIII and, if such Preferred Securities are in definitive form, surrendering such
Preferred Securities, duly endorsed or assigned to the Company or in blank. So
long as any Preferred Securities are outstanding, the Trust shall not convert
any Securities except pursuant to a Notice of Conversion duly executed and
delivered to the Conversion Agent by a holder of Preferred Securities.

         [If a Notice of Conversion is delivered on or after the regular record
date and prior to the subsequent Interest Payment Date, the holder will be
entitled to receive the interest payable on the subsequent Interest Payment Date
on the portion of Securities to be converted notwithstanding the conversion
thereof prior to such Interest Payment Date. Except as otherwise provided in the
immediately preceding sentence, in the case of any Security which is converted,
interest whose due date is after the date of conversion of such Security shall
not be payable, and the Company shall not

                                       53

<PAGE>

make nor be required to make any other payment, adjustment or allowance with
respect to accrued but unpaid interest on the Securities being converted, which
shall be deemed to be paid in full.] Each conversion shall be deemed to have
been effected immediately prior to the close of business on the day on which the
Notice of Conversion was received (the "Conversion Date") by the Conversion
Agent from the holder or from a holder of the Preferred Securities effecting a
conversion thereof pursuant to its conversion rights under the Trust Agreement,
as the case may be. The Person or Persons entitled to receive the Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such Common Stock as of the Conversion Date and such Person
or Persons will cease to be a record holder or record holders of the Securities
on that date; provided, however, that if the transfer books of the Common Stock
shall be closed on said Conversion Date, the Company shall not be required to
issue any shares on such conversion until the date on which such transfer books
shall be reopened and such Person or Persons shall not be deemed to have become
the holder or holders of record of such shares until the date on which such
transfer books shall be reopened, but such conversion shall nevertheless be
effected when such transfer books shall be reopened at the Conversion Price in
effect on and otherwise as of the date on which such Security shall have been
surrendered to and such Notice of Conversion received by the Company as
aforesaid. As promptly as practicable on or after the Conversion Date, the
Company shall issue and deliver at the office of the Conversion Agent, unless
otherwise directed by the holder in the Notice of Conversion, a certificate or
certificates for the number of full shares of Common Stock issuable upon such
conversion, together with the cash payment, if any, in lieu of any fraction of
any share to the Person or Persons entitled to receive the same. The Conversion
Agent shall deliver such certificate or certificates to such Person or Persons.

        (b) Subject to any right of the holder of such Security or any
Predecessor Security to receive interest as provided in Section 2.05(e) and the
second paragraph of clause (a) of Section 13.02, the Company's delivery upon
conversion of the whole number of shares of Common Stock into which the
Securities are convertible (together with the cash payment, if any, in lieu of
fractional shares) shall be deemed to satisfy the Company's obligation to pay
the principal amount at maturity of the portion of Securities so converted and
any unpaid interest (including Additional Payments) accrued on such Securities
at the time of such conversion.

        (c) No fractional shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, the Company shall pay to the Conversion Agent a
cash adjustment in an amount equal to the same fraction of the Closing Price of
such fractional interest on the date on which the Securities or Preferred
Securities, as the case may be, were duly surrendered to the Conversion Agent
for conversion, or, if such day is not a Trading Day, on the next Trading Day,
and the Conversion Agent in turn will make such payment, if any, to the holder
of the Securities or the holder of the Preferred Securities so converted.

        (d) In the event of the conversion of any Security in part only, a new
Security or Securities for the unconverted portion thereof will be issued in the
name of the holder thereof upon the cancellation thereof in accordance with
Section 3.06.

        (e) In effecting the conversion transactions described in this Section,
the Conversion Agent is acting as agent of the holders of Preferred Securities
(in the exchange of Preferred Securities for Securities) and as agent of the
holders of Securities (in the conversion of Securities

                                       54

<PAGE>

into Common Stock), as the case may be, directing it to effect such conversion
transactions. The Conversion Agent is hereby authorized (x) if the Trust exists,
(i) to exchange Securities held by or on behalf of the Trust from time to time
for Preferred Securities in connection with the conversion of such Preferred
Securities in accordance with this Article XIII and (ii) to convert all or a
portion of the Securities into Common Stock and thereupon to deliver such shares
of Common Stock in accordance with the provisions of this Article XIII and to
deliver to the Trust a new Security or Securities for any Securities held by the
holders and not converted in connection with the conversion of such Securities
in accordance with this Article XIII and (y) if the Trust has been dissolved and
the Securities have been distributed to the holders of the Preferred Securities,
to convert all or a portion of the Securities into Common Stock and thereupon to
deliver such shares of Common Stock in accordance with the provisions of this
Article XIII and to deliver to such holders a new Security or Securities for any
resulting unconverted principal amount.

SECTION 13.03     Conversion Price Adjustments.
                  ----------------------------

        The Applicable Conversion Price shall be subject to adjustment (without
duplication) from time to time as follows:__________________.

SECTION 13.04     Reclassification, Consolidation, Merger or Sale of Assets.
                  ---------------------------------------------------------

        In the event that the Company shall be a party to any transaction
(including without limitation (a) any 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), (b) 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 outstanding shares of Common Stock of
the Company), (c) any sale or transfer of all or substantially all of the assets
of the Company or (d) any compulsory share exchange) (each of the events in the
preceding clauses (a) through (d) being referred to as a "Company Transaction"),
in each case, as a result of which shares of Common Stock shall be 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 Company Transaction whereby
the holder of each Security then outstanding shall have the right thereafter to
convert such Security only into the kind and amount of securities, cash and
other property receivable upon the consummation of the Company Transaction by a
holder of that number of shares of Common Stock into which such Security was
convertible immediately prior to such transaction. Holders of the Securities
shall have no voting rights with respect to any Company Transaction described in
this Section 13.04.

        The Company or the Person formed by such consolidation or resulting from
such merger or which acquired such assets or which acquires the Company's
shares, as the case may be, shall make provision in its certificate or articles
of incorporation or other constituent document to establish such right. Such
certificate or articles of incorporation or other constituent document shall
provide for adjustments which, for events subsequent to the effective date of
such certificate or articles of incorporation or other constituent document,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article XIII. The above provisions shall similarly apply to
successive transactions of the foregoing type.

shall prepare a certificate signed by the Chief Financial Officer or the
Treasurer of the Company setting forth the adjusted Applicable Conversion Price

and such certificate shall forthwith be filed with the Trustee, the Conversion
Agent, the Property Trustee and the transfer agent for the Preferred Securities

     (b) a notice stating the Applicable Conversion Price has been adjusted and
setting forth the adjusted Applicable Conversion Price shall as soon as
practicable be mailed by the Company to all record holders of Preferred
Securities and the Securities at their last addresses as they appear upon the
stock transfer books of the Company and the books and records of the Trust,
respectively.

SECTION 13.06   Prior Notice of Certain Events.
                ------------------------------

     In case:

         (i)      the Company shall (1) declare any dividend (or any other
distribution) on its Common Stock, other than (A) a dividend payable in shares
of Common Stock or (B) a dividend payable in cash that would not require an
adjustment pursuant to Section 13.03(__) or (2) authorize a tender or exchange
offer that would require an adjustment pursuant to Section 13.03(__);

Common Stock of rights or warrants to subscribe for or purchase any shares of
stock of any class or series or of any other rights or warrants;

         (iii)    of any reclassification of Common Stock (other than a
subdivision or combination of the outstanding Common Stock, or a change in par

<PAGE>

___________, ____, or from the most recent interest payment date (each such
date, an "Interest Payment Date") to which interest has been paid or duly
provided for, [semi-annually] (subject to deferral as set forth herein) in
arrears on [__________ and __________] of each year, commencing ______________,
____, at the rate of ____% per annum until the principal hereof shall have
become due and payable, and on any overdue principal and premium, if any, and
(without duplication and to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the
same rate per annum compounded [semi-annually]. The amount of interest payable
on any Interest Payment Date shall be computed on the basis of a 360-day year of
twelve 30-day months and, for any period less than a full calendar month, the
number of days elapsed in such month. In the event that any date on which the
principal of (or premium, if any) or interest on this Security is payable is not
a Business Day, then the payment payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), except that if such next succeeding Business Day
falls in the next calendar year, then such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on the date such payment is otherwise required. Pursuant to the
Indenture, in certain circumstances the Company will be required to pay
Additional Sums and Compounded Interest (each as defined in the Indenture) with
respect to this Security.

         The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, which shall be at the
close of business on the [_____ day of the month preceding the month in which
the relevant interest payment date falls]. Any such interest installment not
punctually paid or duly provided for shall forthwith cease to be payable to the
holders on such regular record date and may be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on a special record date to be fixed by the Trustee for the payment
of such defaulted interest, notice whereof shall be given to the holders of
Securities not less than 10 days prior to such special record date, or may be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

         The principal of (and premium, if any) and interest (including
Compounded Interest and Additional Sums, if any) on this Security shall be
payable at the office or agency of the Trustee maintained for that purpose in
any coin or currency of the United States of America that at the time of payment
is legal tender for payment of public and private debts; provided, however,
that, payment of interest may be made at the option of the Company by (i) check
mailed to the holder at such address as shall appear in the Security Register or
(ii) by transfer to an account maintained by the Person entitled thereto;
provided that proper written transfer instructions have been received by the
relevant record date. Notwithstanding the foregoing, so long as the Holder of
this Security is the Property Trustee, the payment of the principal of (and
premium, if any) and interest (including Compounded Interest and Additional
Sums, if any) on this Security will be made at such place and to such account as
may be designated by the Property Trustee.

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and junior in right of payment to the prior
payment in full of all Senior Indebtedness, and

this Security is issued subject to the provisions of the Indenture with respect
thereto. Each holder of this Security, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination so provided and (c) appoints the
Trustee his or her attorney-in-fact for any and all such purposes. Each holder
hereof, by his or her acceptance hereof, hereby waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Indebtedness, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

         This Security shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

         The provisions of this Security are continued on the reverse side
hereof and such provisions shall for all purposes have the same effect as though
fully set forth at this place.

                          (FORM OF REVERSE OF SECURITY)

     This Security is one of the Securities of the Company (herein sometimes
referred to as the "Securities"), specified in the Indenture, all issued or to
be issued under and pursuant to an Indenture, dated as of ___________, ___ (the
"Indenture"), duly executed and delivered between the Company and
___________________, as Trustee (the "Trustee"), to which Indenture reference is
hereby made for a description of the rights, limitations of rights, obligations,
duties and immunities thereunder of the Trustee, the Company and the holders of
the Securities.

     [Upon the occurrence and continuation of a Special Event at any time, the
Company shall have the right, at any time within 90 days following the
occurrence of such Special Event, to redeem this Security in whole (but not in
part) at the Special Event Redemption Price. "Special Event Redemption Price"
shall mean, with respect to any redemption of the Securities following a Special
Event, an amount in cash equal to ________.]

     [In addition, the Company shall have the right to redeem this Security, in
whole or in part, at any time (an "Optional Redemption"), at a redemption price
(the "Optional Redemption Price") equal to ________.]

     [The Optional Redemption Price or the Special Event Redemption Price, as
the case requires, shall be paid prior to 12:00 noon, New York City time, on the
date of such redemption or at such earlier time as the Company determines;
provided, that the Company shall deposit with the Trustee an amount sufficient
to pay the applicable Redemption Price by 10:00 a.m., New York City time, on the
date such Redemption Price is to be paid. Any redemption pursuant to this
paragraph will be made upon not less than 30 days nor more than 60 days notice.
If the Securities are only partially redeemed by the Company pursuant to an
Optional Redemption, the particular Securities to be redeemed shall be selected
on a pro rata basis not more than 60 days prior to the date fixed for redemption
from the outstanding Securities not previously called for redemption; provided,
however, that any such proration may be made on the basis of the aggregate
principal amount of Securities held by each Securityholder thereof and may be
made by making such adjustments as the Company deems fair and appropriate in
order that only Securities in denominations of [$1,000] or integral multiples
thereof shall be redeemed.

     [The holder of any Security has the right, exercisable at any time prior to
5:00 p.m., New York City time, on _____________, to convert the principal amount
thereof (or any portion thereof that is an integral multiple of $____) into [a
number of fully paid and nonassessable shares of Common Stock equal to the $____
principal amount per Security divided by the initial conversion price of $___
(the "Initial Conversion Price") (equal to an initial conversion ratio of
approximately _____shares of Common Stock for each $___ in aggregate principal
amount of Securities).] The conversion price and equivalent conversion ratio are
subject to adjustment under certain circumstances. If a Security is called for
redemption, the conversion right will terminate at the close of business on the
Business Day immediately preceding the corresponding Redemption Date, unless the
Company defaults in making the payment due upon redemption.

     To convert a Security, a holder must (1) complete and sign a conversion
notice substantially in the form attached hereto, (2) surrender the Security to
a Conversion Agent, (3) furnish appropriate

                                      A-6

<PAGE>

endorsements or transfer documents if required by the Security Registrar or
Conversion Agent and (4) pay any transfer or similar tax, if required. Upon
conversion, no adjustment or payment will be made for interest or dividends, but
if any holder surrenders a Security for conversion after the close of business
on the regular record date for the payment of an installment of interest and
prior to the opening of business on the next Interest Payment Date, then,
notwithstanding such conversion, the interest payable on such Interest Payment
Date will be paid to the registered holder of such Security on such regular
record date. In such event, such Security, when surrendered for conversion, need
not be accompanied by payment of an amount equal to the interest payable on such
Interest Payment Date on the portion so converted. The number of shares issuable
upon conversion of a Security is determined by dividing the principal amount of
the Security converted by the Applicable Conversion Price in effect on the
Conversion Date. No fractional shares will be issued upon conversion but a cash
adjustment will be made for any fractional interest. The outstanding principal
amount of any Security shall be reduced by the portion of the principal amount
thereof converted into shares of Common Stock.]

     In the event of redemption of this Security in part only, a new Security or
Securities for the unredeemed portion hereof will be issued in the name of the
holder hereof upon the cancellation hereof.

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

     The Indenture contains provisions for satisfaction and discharge of the
entire indebtedness of this Security upon compliance by the Company with certain
conditions set forth in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of a majority in aggregate principal amount of
the Securities at the time outstanding, as defined in the Indenture, to execute
supplemental indentures for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of the Indenture or of
modifying in any manner the rights of the holders of the Securities; provided,
however, that no such supplemental indenture shall, without the consent of each
holder of Securities then outstanding and affected thereby, (i) change the
Maturity Date of any Securities, or reduce the principal amount thereof, or
reduce any amount payable on redemption thereof, or reduce the rate or extend
the time of payment of interest thereon (subject to Section 2.13 of the
Indenture), or make the principal of, or interest or premium on, the Securities
payable in any coin or currency other than U.S. dollars, or impair or affect the
right of any holder of Securities to institute suit for the payment thereof [or
adversely affect the right to convert such Security], or (ii) reduce the
aforesaid percentage of Securities, the holders of which are required to consent
to any such supplemental indenture. The Indenture also contains provisions
permitting the holders of a majority in aggregate principal amount of the
Securities at the time outstanding affected thereby, on behalf of all of the
holders of the Securities, to waive any past default in the performance of any
of the covenants contained in the Indenture, or established pursuant to the
Indenture, and its consequences, except a continuing default in the payment of
the principal of or premium, if any, or interest on any of the Securities or a
default in respect of any covenant or provision under which the Indenture cannot
be modified or amended without the consent of each

                                      A-7

<PAGE>

holder of Securities then outstanding. Any such consent or waiver by the holder
of this Security (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future holders and owners
of this Security and of any Security issued in exchange herefor or in place
hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this
Security.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and premium, if any, and
interest (including Compounded Interest and Additional Sums, if any) on this
Security at the time and place and at the rate and in the money herein
prescribed [or to convert this Security as provided in the Indenture].

     So long as no Event of Default shall have occurred and be continuing, the
Company shall have the right, at any time and from time to time during the term
of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding [10] consecutive
[semi-annual] periods, including the first such [semi-annual] period during such
extension period, and not extending beyond the Maturity Date of the Securities
(an "Extended Interest Payment Period"), at the end of which period the Company
shall pay all interest then accrued and unpaid (together with interest thereon
at the rate specified for the Securities to the extent that payment of such
interest is enforceable under applicable law). Before the termination of any
such Extended Interest Payment Period, the Company may further defer payments of
interest by further extending such Extended Interest Payment Period; provided
that such Extended Interest Payment Period, together with all such previous and
further extensions within such Extended Interest Payment Period, shall not
exceed [10] consecutive [semi-annual] periods, including the first [semi-annual]
period during such Extended Interest Payment Period and shall not extend beyond
the Maturity Date of the Securities. Upon the termination of any such Extended
Interest Payment Period and the payment of all accrued and unpaid interest and
any additional amounts then due, the Company may commence a new Extended
Interest Payment Period, subject to the foregoing requirements. The Company has
