                                     OSCA
                            STOCK COMPENSATION PLAN

1.  Shares Subject to Plan.  1,000,000 shares of common stock, par value $.01
per share ("Common Stock") of Osca (the "Corporation") shall be reserved for
Awards granted under this Plan (the "Plan"). If any Award granted under this
Plan shall terminate or expire without being fully exercised for any reason
prior to the end of the period under which Awards may be granted, the shares of
Common Stock to which such termination or expiration relates shall again become
available for Awards thereafter granted.

2.  Effective Date and Duration.  This Plan shall become effective on the date
of the consummation of the Corporation's initial public offering and shall
continue in effect for a period of ten (10) years from such date. Upon
expiration of such ten-year period, no further Awards shall be granted (although
unexercised Awards theretofore granted shall continue in effect).

3.  Awards.  The Board may grant Options, including Incentive Stock Options
meeting the requirements of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code") and Non-Qualified Options, and other stock-based awards,
collectively referred to as "Awards."

4.  Administration of the Plan. The Board of Directors of the Corporation (the
"Board"), which may act through its Compensation and Incentive Committee (the
"Committee"), shall administer this Plan.  It may in its sole discretion
determine the person or persons to whom Awards are to be granted and the number
of shares to be covered by each such Award, all within the limitations set forth
in this Plan.  It may interpret the provisions of this Plan and decide all
questions of fact arising out of its application, and all such interpretations
and determinations shall be conclusive and binding upon the individual employees
and directors involved and all persons claiming under them.

5.  Persons Eligible for Awards.  Individuals who are (a) executive officers,
(b) other key employees (including those who are also directors) or (c) non-
employee directors, in each case of the Corporation or any of its subsidiaries,
may be granted Awards.  For this purpose, the term "subsidiary" shall mean any
corporation in which the Corporation owns stock having 50 percent or more of the
total combined voting power of all classes of such corporation's stock.

6.  Terms and Conditions of Options. Options granted may be either Incentive
Stock Options as defined in Section 422 of the Code, (hereinafter referred to as
"ISOs") or options which are not within the 422 definition (hereinafter referred
to as "Non-Qualified Options") (ISOs and Non-Qualified Options are referred to
collectively as "Options").
<PAGE>

(a)  Incentive Stock Options. The terms of each ISO granted shall include those
terms which are required by Section 422 of the Code, and other such terms not
inconsistent therewith as the Board may determine.

(b)  Non-Qualified Options.  Subject to the minimum option price specified in
paragraph (c), the terms of each Non-Qualified Option granted, which may be
different in each case, shall be determined by the Board.

(c)  Minimum Option Price. The option price payable for the shares of Common
Stock subject to each Option granted shall not be less than the fair market
value of the Corporation's Common Stock at the time of the grant of that Option.
The fair market value of the Corporation's Common Stock at the time of the grant
of an Option shall be deemed to be equal to the closing price on the preceding
trading day on the [New York Stock Exchange]; provided, however, that during the
60-day period from and after a change in control of the Corporation, "fair
market value" shall mean, other than in the case of shares of Common Stock
subject to ISOs, the higher of (X) the highest closing price of the Common Stock
on the New York Stock Exchange during the 60-day period prior to the change in
control of the Corporation and (Y) if the change in control of the Corporation
is the result of a transaction or series of transactions described in paragraphs
(a), (b) or (c) of Section 12(A)(iv) hereof, the highest price for shares of
Common Stock paid in such transaction or series of transactions, which in the
case of such paragraph (a) shall be the highest price for shares of Common Stock
as reflected in a Schedule 13D filed under the Exchange Act (as defined in
Section 12(A)(iv)(a) hereof) by the person having made the acquisition.

(d)  Maximum Number of Shares.  Subject to the provisions of Paragraph 11
hereof, the maximum number of shares that may be awarded to any participant in
any year hereunder shall not exceed 150,000.

7.  Terms and Conditions of Other Stock-Based Awards.  The Committee may grant
other stock-based Awards either alone or in addition to other Awards under the
Plan.  The Committee will place such restrictions on such awards as the
Committee determines to be necessary.

8.  Transfer Limitations.  Except as may be determined by the Board or the
Committee, no Award granted shall be transferable otherwise than by will or the
laws of descent and distribution, and no Award granted may be exercised by any
person other than the person to whom the Award shall initially have been granted
during the lifetime of such initial Awardee.

9.  Exercise of Awards.  Awards shall be exercised by written notice to the
Corporation,
<PAGE>

which written notice must be accompanied by payment in full of the option price.
Options may be exercised in one or more installments. Payment of the option
price may be made as specified in each Award Agreement (as discussed below), (a)
in cash, (b) by exchanging Common Stock of the Corporation already owned by the
optionee for at least six months prior to the date of exercise, (c) by delivery
of a combination of cash and Common Stock, (d) through the delivery of a notice
that the optionee has placed a market sell order with a broker with respect to
shares of Common Stock then issuable to the optionee upon exercise of the
Option, and that the broker has been directed to pay a sufficient portion of the
net proceeds of the sale to the Corporation in satisfaction of the aggregate
exercise price of the Option or the exercised portion thereof or (e) by such
other method as the Committee may determine. The exchanged shares, plus cash, if
any, must be equal to the aggregate option price of the shares acquired upon
exercise of the Option. The value to be used for any exchanged shares shall be
the closing market price of the Corporation's Common Stock on the preceding
trading day on the New York Stock Exchange. Notwithstanding the foregoing,
during the 60-day period from and after a change in control of the Corporation,
all optionees, with respect to any or all of their respective Options, shall,
unless the Committee shall determine otherwise at the time of grant, have the
right, in lieu of the payment of the full Option price of the shares of Common
Stock being purchased under the Options and by giving written notice to the
Corporation in form satisfactory to the Committee, to elect (within such 60-day
period) to surrender all or part of the Options to the Corporation and to
receive in cash an amount equal to the amount by which the fair market value of
shares of Common Stock on the date of exercise exceeds the option price per
share of Common Stock under the Options multiplied by the number of shares of
Common Stock granted under the Options as to which the right granted by this
sentence shall have been exercised.

(a)  Mandatory Withholding Taxes.  Whenever a Non-Qualified Option is exercised,
the Corporation may require as a condition of delivery that the optionee remit
an amount sufficient to satisfy all federal, state and local withholding tax
requirements related thereto. The optionee may elect to pay the tax by remitting
(1) cash, (2) shares of Common Stock already owned by the optionee for at least
six months, (3) withholding a portion of the shares otherwise deliverable to the
optionee upon the exercise, or (4) by any combination of the above. The value to
be used for any shares delivered or withheld shall be the closing market price
on the preceding trading day on the New York Stock Exchange.

(b)  Disqualifying Dispositions of ISO Shares.  An optionee shall be required to
notify the Corporation of any disposition of shares issued pursuant to the
exercise of an ISO under the circumstances described in Section 421(b) of the
Code (relating to certain disqualifying dispositions), within ten days of such
disposition.

10.  Award Agreement.  No person shall have any rights with respect to an Award
unless and until the Corporation and the person to whom such Award shall have
been granted shall have executed and delivered an Award Agreement containing
provisions setting forth terms of the
<PAGE>

Awards.

11.  Anti-Dilution Provision.  If, prior to the complete exercise of any Award,
there shall be declared and paid a stock dividend upon the shares of Common
Stock of the Corporation or if the shares shall be split up, converted,
reclassified, changed into, or exchanged for, a different number or kind of
securities of the Corporation, the Award, to the extent that it has not been
exercised, shall entitle the holder upon the future exercise of such Award to
such number and kind of securities or other property subject to the terms of the
Award to which the holder would be entitled had such holder actually owned the
shares subject to the unexercised portion of the Award at the time of the
occurrence of such stock dividend, split-up, conversion, exchange,
reclassification or exchange; and the aggregate purchase price upon the future
exercise of the Award shall be the same as if originally optioned or awarded
shares were being purchased thereunder; or the Committee shall make such other
adjustment to such Award as it deems appropriate.  If any such event should
occur, the number of shares with respect to which Awards remain to be issued, or
with respect to which Awards may be reissued, shall be similarly adjusted.

     In the event the outstanding shares of Common Stock shall be changed into
or exchanged for any other class or series of capital stock or cash, securities
or other property pursuant to a recapitalization, reclassification, merger,
consolidation, combination or similar transaction (other than a transaction
described in the previous paragraph), then each Award shall thereafter become
exercisable for the number and/or kind of capital stock, and/or the amount of
cash, securities or other property so distributed, into which the shares subject
to the Award would have been changed or exchanged had the Award been exercised
in full prior to such transaction, provided that, if the kind or amount of
capital stock or cash, securities or other property received in such transaction
is not the same for each outstanding share, then the kind or amount of capital
stock or cash, securities or other property for which the Award shall thereafter
become exercisable shall be the kind and amount so receivable per share by a
plurality of the shares; or the Committee shall make such other adjustment to
such Award as it deems appropriate.  If any such event should occur, the number
of shares with respect to which Awards remain to be issued or with respect to
which Awards may be reissued, shall be similarly adjusted.

12.  Additional Provisions.

A.  Vesting, Termination of Employment or Service.

(i)  Upon a change in control of the Corporation (as defined below), all Options
shall
<PAGE>

immediately vest and become exercisable and all restrictions on other Awards
shall immediately lapse.

(ii)  Except as otherwise determined by the Board or the Committee, an Award may
be exercised after the termination of an Awardee's employment or service with
the Corporation only to the extent that (a) the Awardee was entitled to do so on
the date of termination (after giving effect to Section 12(A)(i) above), and (b)
the Award would not have expired prior to the date of such exercise had the
Awardee continued to be employed by (or to be in the service of) the
Corporation.

(iii)  The Board (or if such authority is delegated by the Board, the Committee
or the Chief Executive Officer) may in its discretion determine that an
authorized leave of absence or disability shall be deemed to satisfy this Plan's
employment or service requirements.

(iv)  For purposes of this Plan, a "change in control of the Corporation" shall
be deemed to have occurred if the conditions set forth in any one of the
following paragraphs shall have been satisfied:

(a)  any "person" (as such term is used in Section 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) other than (i)
the Corporation, (ii) a trustee or other fiduciary holding securities under an
employee benefit plan of the Corporation, (iii) an underwriter temporarily
holding securities pursuant to an offering of such securities, or (iv) a
corporation owned, directly or indirectly, by the stockholders of the
Corporation in substantially the same proportions as their ownership of shares
of the Corporation (any such person is hereinafter referred to as a "Person"),
is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Corporation
representing more than 20% of the combined voting power of the Corporation's
then outstanding securities (not including in the securities beneficially owned
by such Person any securities acquired directly from the Corporation), excluding
any Person who becomes such a beneficial owner in connection with a transaction
described in clause (i) of paragraph (b) below;

(b)  there is consummated a merger or consolidation of the Corporation or any
direct or indirect subsidiary of the Corporation with or into any other
corporation, other than (i) a merger or consolidation which results in the
directors of the Corporation immediately prior to such merger or consolidation
continuing to constitute at least a majority of the Board of Directors of the
Corporation, the surviving entity or any parent thereof or (ii) a merger or
consolidation effected to implement a recapitalization of the Corporation (or
similar transaction) in which no Person is or becomes the beneficial owner,
directly or indirectly, of securities of the Corporation (not including in the
securities beneficially owned by such Person any securities acquired directly
from the Corporation) representing 20% or more of the combined voting power of
the
<PAGE>

Corporation's then outstanding securities:

(c)  the stockholders of the Corporation approve any plan or proposal for the
liquidation or dissolution of the Corporation or there is consummated an
agreement for the sale or disposition by the Corporation of all or substantially
all the Corporation's assets, other than a sale or disposition by the
Corporation of all or substantially all of the Corporation's assets to an
entity, at least a majority of whose directors were directors of the Corporation
immediately prior to such sale or disposition; or

(d)  during any period of two consecutive years (not including any period prior
to the date of this Plan), individuals who at the beginning of such period
constitute the Board and any new director (other than a director whose initial
assumption of office is in connection with an actual or threatened election
contest, including but not limited to a consent solicitation, relating to the
election of directors of the Corporation) whose appointment or election by the
Board or nomination for election by the Corporation's stockholders was approved
or recommended by a vote of at least two-thirds (2/3) of the directors then
still in office who either were directors at the beginning of the period or
whose appointment, election or nomination for election was previously so
approved, cease for any reason to constitute a majority thereof.

For purposes of this Plan, where a change in control of the Corporation results
from a series of related transactions, the change in control of the Corporation
shall be deemed to have occurred on the date of the consummation of the first
such transaction.

Notwithstanding any other provision hereof, a "change in control of the
Corporation" shall not be deemed to have occurred by virtue of the consummation
of any transaction or series of integrated transactions immediately following
which the record holders of the common stock of the Corporation immediately
prior to such transaction or series of transactions continue to have
substantially the same proportionate ownership in an entity which owns all or
substantially all of the assets of the Corporation immediately following such
transaction or series of transactions.

B.  Listings, Registration and Compliance With Laws and Regulations.

(i)  Each Award shall be subject to the requirement that if at any time the
Board shall determine, in its discretion, that the listing, registration, or
qualification of the shares subject to the Award upon any securities exchange or
under any state or federal securities or other law or regulation, or the consent
or approval of any governmental regulatory body, is necessary or desirable as a
condition to or in connection with the granting of such Award or the issue or
purchase of shares thereunder, no such Award may be exercised or paid in Common
Stock in whole or in part unless such listing, registration, qualification,
consent or approval shall have been effected or obtained
<PAGE>

free of any conditions not acceptable to the Board and the Awardee will supply
the Corporation with such certificates, representations and information as the
Corporation shall request and shall otherwise cooperate with the Corporation in
obtaining such listing, registration, qualification, consent or approval. In the
case of executive officers and other persons subject to Section 16(b) of the
Securities Exchange Act of 1934, the Board may at any time impose any
limitations upon the exercise of an Award which, in the Board's discretion, are
necessary or desirable in order to comply with Section 16(b) and the rules and
regulations thereunder. Prior to the occurrence of a change in control of the
Corporation, if the Corporation, as part of an offering of securities or
otherwise, finds it desirable because of federal or state regulatory
requirements to reduce the period during which any Award may be exercised, the
Board may, in its discretion and without the Awardee's consent, so reduce such
period on not less than 15 days written notice to the Awardee.

(ii)  Notwithstanding the terms of this paragraph, no Awardee shall have the
right to require the Corporation to register, list or qualify said Award or any
of the stock underlying such Option.

C.  Amendment of the Plan.  Except as provided in the following sentence and as
required by law, the Corporation's Board shall have complete power and authority
to amend this Plan at any time and no approval by the Corporation's stockholders
or by any other person, committee or other entity of any kind shall be required
to make any such amendment effective.  The Board shall not, however, increase
the maximum number of shares available for Awards granted unless such increase
shall either be approved by the Corporation's stockholders or shall be permitted
by Paragraph 11.  No termination or amendment may, without consent of the
individual to whom any Award shall have been granted under the Plan, adversely
affect the rights of such individual under such Award.

D.  Captions.  The captions (i.e., all boldfaced words) are for convenience
only, do not constitute a part of this Plan, and shall not be deemed to limit,
characterize or affect in any way any provisions of this Plan, and all
provisions shall be construed as if no captions had been used.

E.  Severability.  Whenever possible, each provision in this Plan and in every
Award at any time granted under this Plan shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Plan or any Award at any time granted under this Plan shall be held to be
prohibited by or invalid under applicable law, then (i) such provision shall be
deemed amended to accomplish the objectives of the provision as originally
written to the fullest extent permitted by law, and (ii) all other provisions
and every Award at any time granted under this Plan shall remain in full force
and effect.
<PAGE>

F.  No Strict Construction.  No rule of strict construction shall be applied
against the Corporation, the Board, or any other person in the interpretation of
any of the terms of this Plan, any Award granted under this Plan or any rule or
procedure established by the Board or the Committee.

G.  Applicable Law.  Every Award at any time granted under this Plan shall be
deemed to be a contract made under the laws of the State of [Indiana].  For all
purposes, both this Plan and every Award granted under this Plan shall be
construed in accordance with and governed by the laws of the State of [Indiana].<PAGE>

instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is

or other action provided or permitted by this Indenture to be given, made or

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

      (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of a notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him or her the execution thereof.
Where such execution is by a Person acting in other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution by any Person of any
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

      (c) The ownership of Securities shall be proved by the Securities
Register.

                                      -11-
<PAGE>

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

      (e) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided, that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in paragraph (f) of this Section.
If any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided, that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect). Promptly after any record date is set pursuant
to this paragraph, the Company, at its own expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 1.6.

      (f) The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(b) or (iv) any direction referred to in
Section 5.12, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided, that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by

                                      -12-
<PAGE>

any Person be cancelled and of no effect). Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 1.6.

      (g) With respect to any record date set pursuant to paragraph (e) or (f)
of this Section, the party hereto that sets such record date may designate any
day as the "Expiration Date" and from time to time may change the Expiration
Date to any earlier or later day; provided, that no such change shall be
effective unless notice of the proposed new Expiration Date is given to the
other party hereto in writing, and to each Holder of Securities of the relevant
series in the manner set forth in Section 1.6, on or prior to the existing
Expiration Date. If an Expiration Date is not designated with respect to any
record date set pursuant to this Section, the party hereto which set such record
date shall be deemed to have initially designated the 180th day after such
record date as the Expiration Date with respect thereto, subject to its right to
change the Expiration Date as provided in this paragraph.

      (h) Without limiting the foregoing, a Holder entitled to take any action
hereunder with regard to any particular Security may do so with regard to all or
any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

Section 1.5.  Notices, Etc., to Trustee and Company.

      Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with:

        (a) the Trustee by any Holder or by the Company shall be sufficient for
   every purpose hereunder if made, given, furnished or filed in writing to or
   with the Trustee at its Corporate Trust Office, or

        (b) the Company by the Trustee or by any Holder shall be sufficient for
   every purpose (except as otherwise provided in Section 5.1) hereunder if in
   writing and mailed, first-class, postage prepaid, to the Company addressed to

Section 1.6.  Notice to Holders; Waiver.

      Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at the address of such Holder as it appears in the Securities
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. If, by
reason of the suspension of or irregularities in regular mail service or for any
other reason, it shall be impossible or impracticable to mail notice of any
event to Holders when said notice is required to be given pursuant to any
provision of this Indenture or any Security, then any manner of giving such
notice as shall be satisfactory to the Trustee shall be deemed to be sufficient
notification for every purpose hereunder. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

Section 1.7.  Conflict with Trust Indenture Act.

      If any provision of this Indenture limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act which may be so modified or excluded, the provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

Section 1.8.  Effect of Headings and Table of Contents.

      The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

Section 1.9.  Successors and Assigns.

      All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.

Section 1.10.  Separability Clause.

      If any provision in this Indenture or in the Securities shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

Section 1.11.  Benefits of Indenture.

      Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors and the
Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture.

Section 1.12.  Governing Law.

      This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York, without regard to conflict of
laws provisions thereof.

Section 1.13.  Non-Business Days.

      If any Interest Payment Date, Redemption Date or Stated Maturity of any
Security shall not be a Business Day, then (notwithstanding any other provision
of this Indenture or of the Securities (other than a provision of any Security
which specifically states that such provision shall apply in lieu of this
Section)) payment of interest, premium or principal on or other amounts in
respect of such Security need not be made on such date, but may be made on the
next succeeding Business Day (and no interest shall accrue in respect of the
amounts whose payment is so delayed for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be, until such
next succeeding Business Day) except that, if such Business Day falls in the
next succeeding calendar year, 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 Interest Payment Date or Redemption Date or at the Stated Maturity).

Section 1.14.  Indenture and Securities Solely Corporate Obligations.

      No recourse for the payment of the principal of, any premium or interest
on or any other amounts with respect to any Security, or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in this Indenture or in any
supplemental indenture, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past,

present or future, of the Company or of any successor company, whether by virtue

assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as
consideration for, the execution of this Indenture and the issue of the

outstanding until the appointment of a successor by the Company and such
successor's acceptance of such appointment. Upon such acceptance, the Company
shall notify the Trustee of the name and address of such successor. The Company

responsibility, with respect to any failure by the Company to take any such
action. Nothing herein shall affect the right of the Trustee or any Holder to
institute proceedings against the Company in the courts of any other
jurisdiction or jurisdictions.

its Vice Presidents, and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be

individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to

      (b) At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 2.1 and 3.1,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in

                                      -26-
<PAGE>

relation to such Securities, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating:

         (i)   if the form of such Securities has been established by or
   pursuant to Board Resolution as permitted by Section 2.1, that such form has
   been established in conformity with the provisions of this Indenture;

         (ii)  if the terms of such Securities have been established by or
   pursuant to Board Resolution as permitted by Section 3.1, that such terms
   have been established in conformity with the provisions of this Indenture;
   and

         (iii) that such Securities, when authenticated and delivered by the
   Trustee and issued by the Company in the manner and subject to any conditions
   specified in such Opinion of Counsel, will constitute valid and legally
   binding obligations of the Company enforceable in accordance with their
   terms, subject to bankruptcy, insolvency, fraudulent transfer,
   reorganization, moratorium and similar laws of general applicability relating
   to or affecting creditors' rights and to general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties,
indemnities or immunities under the Securities and this Indenture or otherwise
in a manner that is not reasonably acceptable to the Trustee.

      (c) Notwithstanding the provisions of Section 3.1 and of paragraph (b) of
this Section, if all Securities of a series are not to be originally issued at
one time, it shall not be necessary to deliver the Officers' Certificate
otherwise required pursuant to Section 3.1 or the Company Order and Opinion of
Counsel otherwise required pursuant to paragraph (b) of this Section at or prior
to the authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

      (d) No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of an authorized officer, and
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for can cellation as
provided in Section 3.10, for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.

                                      -27-
<PAGE>

      (e)  Each Security shall be dated the date of its authentication.

Section 3.4. Temporary Securities.

      (a)  Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities that are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denom ination,
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
evidenced by their execution of such Securities.

      (b) If temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay. 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 of the Company designated for that purpose,
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 deliver in exchange therefor one or more definitive Securities
of the same series, of any authorized denom inations having the same Original
Issue Date and Stated Maturity and having the same terms as such temporary
Securities. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

Section 3.5. Global Securities.

      (a) Each Global Security issued under this Indenture shall be registered
in the name of the Depositary designated by the Company for such Global Security
or a nominee thereof and delivered to such Depositary or a nominee thereof or
custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture.

      (b) Notwithstanding any other provision in this Indenture, no Global
Security may be exchanged in whole or in part for Securities registered, and no
transfer of a Global Security in whole or in part may be registered, in the name
of any Person other than the Depositary for such Global Security or a nominee
thereof unless (i) such Depositary advises the Trustee and the Company in
writing that such Depositary is no longer willing or able to properly discharge
its responsibilities as Depositary with respect to such Global Security and no
qualified successor is appointed by the Company within 90

                                      -28-
<PAGE>

days of receipt by the Company of such notice, (ii) such Depositary has ceased
to be a clearing agency registered under the Exchange Act and no qualified
successor is appointed by the Company within 90 days after its receipt of notice
or its becoming aware of such event, (iii) the Company executes and delivers to
the Trustee a Company Order stating that the Company elects to terminate the
book-entry system through the Depositary, or (iv) there shall have occurred and
be continuing an Event of Default with respect to such Global Security.

      (c) If any Global Security is to be exchanged for other Securities or
cancelled in whole, it shall be surrendered by or on behalf of the Depositary or
its nominee to the Securities Registrar for exchange or cancellation as provided
in this Article. If any Global Security is to be exchanged for other Securities
or cancelled in part, or if another Security is to be exchanged in whole or in
part for a beneficial interest in any Global Security, then either (i) such
Global Security shall be so surrendered for exchange or cancellation as provided
in this Article or (ii) the principal amount thereof shall be reduced or
increased by an amount equal to the portion thereof to be so exchanged or
cancelled, or equal to the principal amount of such other Security to be so
exchanged for a beneficial interest therein, as the case may be, by means of an
appropriate adjustment made on the records of the Securities Registrar,
whereupon the Trustee, in accordance with the Applicable Procedures, shall
instruct the Depositary or its authorized representative to make a corresponding
adjustment to its records. Upon any such surrender or adjustment of a Global
Security by the Depositary, accompanied by registration instructions, the
Trustee shall, subject to this Section and as otherwise provided in this
Article, authenticate and deliver any Securities issuable in exchange for such
Global Security (or any portion thereof) in accordance with the instructions of
the Depositary. The Trustee shall not be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions.

      (d) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Article, Section 9.6 or 11.7 or otherwise,
shall be authenticated and delivered in the form of, and shall be, a Global
Security, unless such Security is registered in the name of a Person other than
the Depositary for such Global Security or a nominee thereof.

      (e) The Depositary or its nominee, as the registered owner of a Global
Security, shall be the Holder of such Global Security for all purposes under
this Indenture and the Securities, and owners of beneficial interests in a

respect of any transfers effected by the Depositary.

      (f) The rights of owners of beneficial interests in a Global Security

Section 3.6.  Registration, Transfer and Exchange.

      (a) The Company shall cause to be kept at the Corporate Trust Office a
register in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Securities and of transfers of
Securities (the "Securities Register"). The Trustee is hereby appointed
"Securities Registrar" for the purpose of registering Securities and transfers
of Securities as herein provided.

      (b) Upon surrender for registration of transfer of any Security of a
series at the office or agency of the Company designated for that purpose, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series of any authorized denominations and of like tenor and aggregate
principal amount.

      (c) At the option of the Holder, Securities of a series may be exchanged
for other Securities of the same series of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities that the Holder making the exchange is
entitled to receive.

      (d) All Securities issued upon any transfer or exchange of Securities
shall be the valid obli gations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities
surrendered upon such transfer or exchange.

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

                                      -30-

      (f) No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities.

      (g) The Company shall not be required (A) to issue, register the transfer
of or exchange any Securities of that series during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 11.3 and
ending at the close of business on the day of such mailing or (B) to 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.

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

Section 3.7.  Mutilated, Destroyed, Lost and Stolen Securities.

      (a) If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Company or the Trustee to
save each of them harmless, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series,
of like tenor and aggregate principal amount and bearing a number not
contemporaneously outstanding.

      (b) If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them harmless, then, in the absence of notice to the Company or the Trustee that
such Security has been acquired by a bona fide purchaser, the Company shall
execute and the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security, a new Security of the same series, of like
tenor and principal amount as such destroyed, lost or stolen Security and
bearing a number not contemporaneously outstanding.

      (c) If any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

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

                                      -31-
<PAGE>

      (e) Every new Security of any series issued pursuant to this Section in
lieu of any mutilated, destroyed, lost or stolen Security shall constitute an
original additional contractual obligation of the Company, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally
and proportionately with any and all other Securities of the same series duly
issued hereunder.

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

Section 3.8.  Payment of Interest; Interest Rights Preserved.

      (a) Except as otherwise contemplated by Section 3.1 with respect to any
series of Securities, interest on any Security of any series that is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest in respect of Securities of such series, except that, unless
otherwise provided in the Securities of such series, interest payable on the
Stated Maturity, redemption or repayment of the principal of a Security shall be
paid to the Person to whom principal is paid. The initial payment of interest on
any Security of any series that is issued between a Regular Record Date and the
related Interest Payment Date shall be payable as provided in such Security or
in the Board Resolution pursuant to Section 3.1 with respect to the related
series of Securities.

      (b) Any interest on any Security of any series that is due and payable,
but is not timely paid or duly provided for, on any Interest Payment Date for
Securities of such series (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 may be paid by the
Company, at its election in each case, as provided in paragraph (i) or (ii)
below:

         (i) The Company may elect to make payment of any Defaulted Interest to
      the Persons in whose names the Securities of such series (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 Security of such series and the date of the proposed payment at
      least 30 days prior to such date, 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

                                      -32-
<PAGE>

      deposited to be held in trust for the benefit of the Persons entitled to
      such Defaulted Interest. Thereupon the Trustee shall fix a Special Record
      Date for the payment of such Defaulted Interest which shall be not more
      than 15 days and not 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 given to each Holder
      of Securities of such series in the manner set forth in Section 1.6, not
      less than 10 days prior to such Special Record Date. Notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor having been so mailed, such Defaulted Interest shall be paid to
      the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on such Special Record Date; or

          (ii) The Company may make payment of any Defaulted Interest on the
      Securities of any series 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.

      (c) Unless otherwise provided in or pursuant to this Indenture or any
supplemental indenture, interest on the Securities of any series will be
payable, at the option of the Company, (i) by check mailed to the address of the
Holder as such address appears in the Securities Register for the Securities of
such series or (ii) by wire transfer to an account at a banking institution in
the United States that the Holder designates in writing to the Trustee at least
10 Business Days prior to the Interest Payment Date.

Section 3.9.  Persons Deemed Owners.

      (a) Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee shall treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of, any premium and
(subject to Section 3.8) interest on and any Additional Amounts with respect to
such Security and for all other purposes whatsoever, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

      (b) No holder of any beneficial interest in any Global Security held on
its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global Security, and such Depositary may be treated by the
Company, the Trustee

                                      -33-
<PAGE>

and any agent of the Company or the Trustee as the owner of such Global Security
for all purposes whatsoever. None of the Company, the Trustee or any agent of
the Company or the Trustee will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of a Global Security or maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by a Depositary or
impair, as between a Depositary and such holders of beneficial interests, the
operation of customary practices governing the exercise of the rights of the
Depositary (or its nominee) as Holder of any Security.

Section 3.10.  Cancellation.

      All Securities surrendered for payment, redemption, transfer or exchange
or for credit against any sinking fund payment shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and any such
Securities delivered to the Trustee for any purpose shall be promptly cancelled
by it. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder that the Company may
have acquired in any manner whatsoever, and may deliver to the Trustee for
cancellation any Securities previously authenticated hereunder that the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of in accordance with its customary practices and the
Trustee shall deliver to the Company a certificate of such disposition.

Section 3.11.  Computation of Interest.

      Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
partial period shall be computed on the basis of a 360-day year of twelve 30-day
months and the actual number of days elapsed in any partial month in such
period, and interest on the Securities of each series for a full period shall be
computed by dividing the rate per annum by the number of interest periods that
together constitute a full twelve months.

Section 3.12.  Shortening and Extending Stated Maturity.

      (a) If specified as contemplated by Section 2.1 or Section 3.1 with
respect to the Securities of any series, the Company shall have the right to
shorten the Stated Maturity of the principal of the Securities of such series at
any time to any date not earlier than the first date on which the Company has
the right to redeem the Securities of such series. In the event that the Company
elects to shorten the Stated Maturity of the Securities of such series, it shall
give written notice to the Trustee.

the Securities of such series, it shall give written notice to the Trustee.

Section 3.13.  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 and other similar or related matters as a convenience to Holders;
provided, that any such notice or other materials 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 redemption or other materials
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.

Securities herein expressly provided for and as otherwise provided in this
Section) and the Trustee, on the demand of and at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture, when

      (a)  either

         (i) all Securities theretofore authenticated and delivered (other than
      (A) Securities that have been mutilated, destroyed, lost or stolen and
      that have

                                      -35-

         one year of the date of deposit, or

               (C)  are to be called for redemption within one year under
         arrangements satisfactory to the Trustee for the giving of notice of
         redemption by the Trustee in the name, and at the expense, of the

      trust for such purpose (x) an amount in the currency or currencies in

      Obligations which through the scheduled payment of principal and interest
      in respect thereof in accordance with their terms will provide, not later
      than the due date of any payment, money in an amount or (z) a combination
      thereof, in each case where any Government Obligations are deposited, in
      the opinion of a nationally recognized firm of independent public
      accountants expressed in a written certification thereof delivered to the
      Trustee, sufficient to pay and dis charge the entire indebtedness on such
      Securities not theretofore delivered to the Trustee for cancellation, for
      principal, any premium and interest and any Additional Amounts in respect
      thereof to the date of such deposit (in the case of Securities that have
      become due and payable) or to the Stated Maturity or Redemption Date, as
      the case may be;

obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall

deposited with the Trustee pursuant to paragraph (a)(ii) of this Section, the
obligations of the Trustee under Section 4.2 and Section 10.3(e) shall survive.

thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of Outstanding Securities.

Section 4.2.  Application of Trust Money.

      Subject to the provisions of Section 10.3(e), all money and Government
Obligations (including the proceeds thereof) deposited with the Trustee pursuant
to Section 4.1 shall be held in trust and applied by the Trustee, in accordance
with the provisions of the Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of

      (a) If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event or Default specified in Section 5.1(g) or

      (b) At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this

      (a)   The Company covenants that if

         (i)   default is made in the payment of any installment of interest on
   or any Additional Amounts, payable with respect to such interest, with
   respect to any Security of any series when such interest or Additional
   Amounts shall have become due and payable and such default continues for a
   period of 30 days, or

         (ii)  default is made in the payment of the principal of or any premium
   on any Security or any Additional Amounts with respect thereto at the
   Maturity thereof, or

         (iii) default is made in the deposit of any sinking fund payment, when
   and as due by the terms of a Security of any series,

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal and any premium and interest and Additional
Amounts and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal, premium interest and Additional
Amounts at the rate prescribed therefor in such Securities, and, in addition
thereto, all amounts owing to the Trustee, its agents and counsel under Section
6.7.

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

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

Trustee shall consent to the making of such payments directly to the Holders, to
pay any amounts due the Trustee, its agents and counsel under Section 6.7.

authorize or consent to or accept or adopt on behalf of any Holder 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 Holder in any such proceeding; provided, that the
Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors' or other similar
committee.

such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of all the amounts owing the Trustee, its agents and counsel
under Section 6.7, be for the ratable benefit of the Holders of the Securities
in respect of which such judgment has been recovered.

liquidator, sequestor (or other similar official) or for any other remedy
hereunder, unless

      (a) such Holder has previously given written notice to the Trustee of a
   continuing Event of Default with respect to the Securities of that series;

      (b) the Holders of not less than a majority in aggregate principal amount
   of the Outstanding Securities of that series shall have made written request
   to the Trustee to institute proceedings in respect of such Event of Default
   in its own name as Trustee hereunder;

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing itself of, any
provision of this Indenture to affect, disturb or prejudice the rights of any
other Holders, or to obtain or to seek to obtain priority or preference over any
other Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all of such Holders.

Security of any series shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject
to Section 3.8) interest on and any Additional Amounts with respect to such

enforcement of any such payment, and such right shall not be impaired without
the consent of such Holder.

Section 5.9.  Restoration of Rights and Remedies.

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

Section 5.10. Rights and Remedies Cumulative.

      Except as otherwise provided in Section 3.7(f), no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

Section 5.11. Delay or Omission Not Waiver.

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

the Trustee, or exercising any trust or power conferred on the Trustee, with
respect to the Securities of such series, provided, that

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

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

      (c)  subject to the provisions of Section 6.1, the Trustee shall have the
   right to decline to follow any such direction if a Responsible Officer or
   Officers of the Trustee shall, in good faith, determine that the proceeding
   so directed would be unjustly prejudicial to the Holders not joining in any
   such direction or involve the Trustee in personal liability.

Section 5.13.  Waiver of Past Defaults.

      (a)  The Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities of any series may on behalf of the Holders of all
the Securities of such series waive any past Event of Default hereunder with
respect to such series and its consequences, except an Event of Default

   deposited with the Trustee a sum sufficient to pay all matured installments
   of interest and all principal of, any premium on and any Additional Amounts
   with respect to all Securities of that series due otherwise than by

every

                                      -45-

purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereon.

court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees 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 shall not apply to any suit

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.

provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reason able grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to

Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

default in the payment of the principal of, any premium or interest on or any
Additional Amounts with respect to any Securities of any series or in the making
of any sinking fund payment payable with respect to Securities of any series,
the Trustee may withhold the 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 withholding the notice is
in the interest of Holders of Securities of that series; and provided, further,
that in the case of any default of the character specified in Section 5.1(d)
with respect to Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to
Securities of such series.

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility

Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections

      (d) The obligations of the Company under this Section shall survive the
satisfaction and discharge of this Indenture, the defeasance of the Securities
and the earlier resignation or removal of the Trustee.

Section 6.9.  Corporate Trustee Required; Eligibility.

      There shall at all times be one (and only one) Trustee hereunder with

Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article. Neither the Company nor any Person directly or indirectly controlling,
controlled by or under common control with the Company shall serve as Trustee
for the Securities of any series issued hereunder.

Section 6.10. Resignation and Removal; Appointment of Successor.

      (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

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

      (c)  The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in aggregate principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company.

      (d)  If at any time:

      (i)  the Trustee shall fail to comply with Section 6.8 after written
   request therefor by the Company or by any Holder who has been a bona fide
   Holder of a Security for at least six months, or

      (ii) the Trustee shall cease to be eligible under Section 6.9 and shall
   fail to resign after written request therefor by the Company or by any such
   Holder, or

                                      -51-
<PAGE>

      (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, (x) the Company, by a Board Resolution, may remove the
Trustee with respect to the Securities of all series issued hereunder or (y)
subject to Section 5.14, any such Holder may, on behalf of such Holder and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to the Securities of all series issued
hereunder and the appointment of a successor Trustee or Trustees.

      (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee with respect to the Securities of
that or those series. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in aggregate principal amount of the Outstanding Securities of
such series delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee with respect to the Securities of such series and
supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, subject to Section 5.14, on
behalf of such Holder and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

      (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series. Each notice shall include the name of the
successor Trustee with respect to the Securities of such series and the address
of its Corporate Trust Office.

Section 6.11.  Acceptance of Appointment by Successor.

      (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring

                                      -52-
<PAGE>

Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

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

hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the

Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall, upon payment of its charges, duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

      (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming

Section 6.12.  Merger, Conversion, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

Section 6.13.  Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

Section  6.14.  Appointment of Authenticating Agent.

     (a) The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue (in accordance with procedures acceptable to the Trustee) and upon
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.7, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, or of any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a

                                      -54-
<PAGE>

combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority. If such Authenticating
Agent publishes reports of condition at least annually, pursuant to law or to
the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

     (c) An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent eligible under the provisions of this Section, which shall be acceptable
to the Company, and shall give notice of such appointment to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.

     (d) The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

     (e) If an appointment of an Authenticating Agent with respect to one or
more series is made pursuant to this Section, the Securities of such series may
have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternative certificate of authentication in the following
form:

                                      -55-

by the Company, in trust for the payment of the principal of, any premium or
interest on or any Additional Amounts with respect to any Security of any series
and remaining unclaimed for two years after such principal, premium or interest
has, or such Additional Amounts have, become due and payable shall (unless
otherwise required by mandatory provision of the applicable escheat or abandoned
or unclaimed property law) be paid on Company Request to the Company, or (if
then held by the Company) shall (unless otherwise required by mandatory
provision of the applicable escheat or abandoned or unclaimed property law) be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, that the Trustee or such Paying Agent, before being required to
make any such repayment, may at the expense of the Company cause to be published
once, in a newspaper published in the English language, customarily published on
each Business Day and of general circulation in the Borough of Manhattan, The
City of New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

Section 10.4.  Statement by Officers as to Compliance.

      The Company shall deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate (one of the signatories to which shall be the principal financial
officer, principal executive officer or principal accounting officer of the
Company) covering the preceding fiscal year, stating whether or not to the
knowledge of the signers thereof the Company is in default in the performance
and observance of any of the terms, provisions and conditions of this Indenture
(without regard to any grace period or requirement of notice provided hereunder)
and, if the Company shall be in default, specifying all such defaults and the
nature and status thereof of which they may have knowledge.

Section 10.5.  Additional Amounts.

      (a) All payments of principal of and premium, if any, interest and any
other amounts on or in respect of the Securities of any series shall be made
without withholding or deduction at source for, or on account of, any present or
future taxes, fees, duties, assessments or governmental charges of whatever
nature imposed or levied by or on behalf of Bermuda or any other jurisdiction in
which the Company is organized or resident for tax purposes (each, a "taxing
jurisdiction") or any political subdivision or taxing authority thereof or
therein, unless such taxes, fees, duties, assessments or governmental charges
are required to be withheld or deducted

                                      -65-
<PAGE>

by (i) the laws (or any regulations or rulings promulgated thereunder) of a
taxing jurisdiction or any political subdivision or taxing authority thereof or
therein or (ii) an official position regarding the application, administration,
interpretation or enforcement of any such laws, regulations or rulings
(including a holding by a court of competent jurisdiction or by a taxing
authority in a taxing jurisdiction or any political subdivision thereof). If any
withholding or deduction at source is required, the Company shall, subject to
the limitations and exceptions set forth below, pay to the Holder of any such
Security such additional amounts as may be necessary so that every net payment
of principal, premium, if any, interest or any other amount made to such Holder,
after such withholding or deduction, shall not be less than the amount provided
for in such Security and this Indenture to be then due and payable (the
"Additional Amounts"); provided, that the Company shall not be required to make
payment of such Additional Amounts for or on account of:

      (i)   any tax, fee, duty, assessment or governmental charge of whatever
   nature that would not have been imposed but for the fact that such Holder or
   the beneficial owner of such Security: (A) was a resident, domiciliary or
   national of, or engaged in business or maintained a permanent establishment
   or was physically present in, the relevant taxing jurisdiction or any
   political subdivision thereof or therein or otherwise had some connection
   with the relevant taxing jurisdiction or any political subdivision thereof or
   therein other than by reason of the mere ownership of, or receipt of payment
   under, such Security; (B) presented such Security for payment in the relevant
   taxing jurisdiction or any political subdivision thereof or therein, unless
   such Security could not have been presented for payment elsewhere; or (c)
   presented such Security more than 30 days after the date on which the payment
   in respect of such Security first became due and payable except to the extent
   that the Holder or beneficial owner would have been entitled to such
   Additional Amounts if it had presented such Security for payment on any day
   within such period of 30 days;

      (ii)  any estate, inheritance, gift, sale, transfer, personal property or
   similar tax, fee, duty, assessment or other governmental charge; or

      (iii) any tax, fee, duty, assessment or other governmental charge that is
   imposed or withheld by reason of the failure by the Holder or the beneficial
   owner of such Security to comply, within 90 days, with any reasonable request
   by the Company addressed to the Holder or such beneficial owner (A) to
   provide information concerning the nationality, residence or identity of the
   Holder or such beneficial owner or (B) to make any declaration or other
   similar claim or satisfy any information or reporting requirement, which, in
   the case of (A) or (B), is required or imposed by statute, treaty, regulation
   or administrative practice of the relevant taxing jurisdiction or any
   political subdivision thereof or therein as a precondition to exemption from
   all or part of such tax, fee, duty, assessment or other governmental charge;

                                      -66-
<PAGE>

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder where the beneficial owner of such Security is a
fiduciary or partnership to the extent such payment would be required by the
laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary with respect to such fiduciary or partner of such
partnership that would not have been entitled to such Additional Amounts had it
been the Holder of the Security.

      (b) Whenever in this Indenture there is mentioned, in any context, the
payment of the principal of or any premium, interest or any other amounts on or
in respect of any Security of any series or the net proceeds received on the
sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of Additional Amounts provided by the terms of
such series established hereby or pursuant hereto to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to such terms, and express mention of the payment of Additional Amounts
(if applicable) in any provision hereof shall not be construed as excluding the
payment of Additional Amounts in those provisions hereof where such express
mention is not made.

      (c) Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, at least 10 days prior to the first
Interest Payment Date with respect to a series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below- mentioned Officer's Certificate,
the Company shall furnish to the Trustee and the principal Paying Agent or
Paying Agents, if other than the Trustee, an Officer's Certificate instructing
the Trustee and such Paying Agent or Paying Agents whether such payment of
principal of and premium, if any, interest or any other amounts on the
Securities of such series shall be made to Holders of Securities of such series
without withholding for or on account of any tax, fee, duty, assessment or other
governmental charge described in this Section. If any such withholding shall be
required, then such Officer's Certificate shall specify by jurisdiction in which
Holders of Securities are resident for tax purposes the amount, if any, required
to be withheld on such payments to such Holders of Securities, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by this Section. The Company covenants to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officer's Certificate furnished pursuant to this Section.

Section 10.6.  Existence.

      Subject to Article VIII and Section 10.9, the Company shall do or cause to
be done all things necessary to preserve and keep in full force and effect its
and its Subsidiaries' existence, rights (charter and statutory) and franchises;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.

Section 10.7.  Payment of Taxes and Other Claims.

      The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon the Company or any of its
Subsidiaries or upon the income, profits or property thereof, and (2) all
material lawful claims for labor, materials and supplies which, if unpaid, might
by law become a lien upon the property of the Company or any of its respective
Subsidiaries; provided, however, that the Company shall be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings and for which adequate reserves have been established
to the extent required by generally accepted accounting principles.

Section 10.8.  Limitation on Liens on Stock of Significant Subsidiaries.

      So long as any Securities are Outstanding, the Company will not, nor will
it permit any Significant Subsidiary at any time, directly or indirectly, to
create, assume, incur, or otherwise permit to exist any Debt secured by any Lien
upon any shares of capital stock of any Significant Subsidiary (whether such
shares of stock are now owned or hereafter acquired) without effectively
providing concurrently that the Securities (and, if the Company so elects, any
other Debt of the Company that ranks equally with the Securities) shall be
secured equally and ratably with or prior to such Debt for at least the time
period such other Debt is so secured; provided, that this Section shall not
apply, with respect to the Securities for any series, to any Debt existing on
the date of the first issuance of Securities of such series that is so secured
and any renewals, extensions or refundings of such Debt.

Section 10.9.  Limitation on Disposition of Stock of Significant Subsidiaries.

      Subject to the provisions of Article VIII, so long as any Securities are
outstanding, the Company will not sell, transfer or otherwise dispose of any
shares of capital stock of any Significant Subsidiary, and will not permit any
Significant Subsidiary to sell, transfer or otherwise dispose of any shares of
capital stock of any other Significant

                                      -68-
<PAGE>

Subsidiary. Notwithstanding the foregoing, (i) the Company may merge or
consolidate any Significant Subsidiary into or with another direct or indirect
Subsidiary of the Company and (ii) the Company may, subject to the provisions of
Article VIII, sell, transfer or otherwise dispose of the entire capital stock of
any Significant Subsidiary at one time for consideration consisting of cash or
other property which is at least equal to the fair market value thereof as
determined by the Board of Directors pursuant to a Board Resolution adopted in
good faith.

Section 10.10.  Original Issue Discount.

      For each year during which any Discount Securities are Outstanding, the
Company shall furnish to each Paying Agent in a timely fashion such information
as may be reasonably requested by each Paying Agent in order that each Paying
Agent may prepare the information which it is required to report for such year
on Internal Revenue Service Forms 1096 and 1099 pursuant to Section 6049 of the
Internal Revenue Code of 1986, as amended. Such information shall include the
amount of original issue discount includible in income for each $25 of principal
amount at Stated Maturity of outstanding Securities during such year.

Section 10.11.  Waiver of Certain Covenants.

      Except as otherwise specified as contemplated by Section 3.1 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any covenant in
Section 10.8 or 10.9 or provided pursuant to Section 3.1 or Section 9.1(a) or
(c) for the benefit of the Holders of such series if before or after the time
for such compliance the Holders of at least a majority in aggregate principal
amount of the Outstanding Securities of such series shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant, but no such waiver shall extend to or affect such
covenant, except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company in respect of any such covenant
shall remain in full force and effect.

                                  ARTICLE XI

                           Redemption of Securities

Section 11.1.  Applicability of Article.

      Securities of any series that are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 3.1 for such Securities) in accordance with
this Article.

Section 11.2.  Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section 3.1
for such Securities. In case of any redemption at the election of the Company,
the Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities (a)
prior to the expiration of any restriction on such redemption provided in the
terms of such Securities or elsewhere in this Indenture or (b) pursuant to an
election of the Company that is subject to a condition specified in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction or condition.

Section 11.3.  Selection of Securities to be Redeemed.

      (a) If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided, that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security.

      (b) The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed. For all
purposes of this Indenture, unless the context otherwise requires, all
provisions relating to the redemption of Securities shall relate, in the case of
any Security redeemed or to be

                                      -70-
<PAGE>

redeemed only in part, to the portion of the principal amount of such Security
that has been or is to be redeemed.

      (c) The provisions of paragraphs (a) and (b) of this Section shall not
apply with respect to any redemption affecting only a single Security, whether
such Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

Section 11.4.  Notice of Redemption.

      (a) Notice of redemption shall be given not less than 30 nor more than 60
days prior to the Redemption Date, to each Holder of Securities to be redeemed.

      (b) With respect to Securities of each series to be redeemed, each notice
of redemption shall state:

      (i)   the Redemption Date;

      (ii)  the Redemption Price or, if the Redemption Price cannot be
   calculated prior to the time the notice is required to be sent, the estimate
   of the Redemption Price, as calculated by the Company, together with a
   statement that it is an estimate and that the actual Redemption Price will be
   calculated on the day provided by the terms of such Securities (and if an
   estimate is provided, a further notice shall be sent of the actual Redemption
   Price on the date that such Redemption Price is calculated);

      (iii) if less than all Outstanding Securities of such series are to be
   redeemed, the identification (and, in the case of partial redemption, the
   principal amounts) of the particular Securities to be redeemed and, if less
   than all the Outstanding Securities of any series consisting of a single
   Security are to be redeemed, the principal amount of the particular Security
   to be redeemed;

      (iv)  that on the Redemption Date the Redemption Price will become due and
   payable upon each such Security or portion thereof, and that interest thereon
   shall cease to accrue on and after said date;

      (v)   the place or places where such Securities are to be surrendered for
   payment of the Redemption Price;

      (vi)  that the redemption is for a sinking fund, if such is the case; and

                                      -71-
<PAGE>

      (vii) such other provisions as may be required in respect of the terms of
   such Securities.

      (c) Unless otherwise specified with respect to any Securities in
accordance with Section 3.1, with respect to any redemption of Securities at the
election of the Company, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 13.2, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent for such Securities, on or
prior to the date fixed for such redemption, of money sufficient to pay the
principal of, any premium and interest on and Additional Amounts with respect to
such Securities and that if such money shall not have been so received such
notice shall be of no force or effect and the Company shall not be required to
redeem such Securities. In the event such notice of redemption contains such a
condition and such money is not so received, the redemption shall not be made
and within a reasonable time thereafter notice shall be given, in the same
manner in which the notice of redemption was given, that such money was not so
received and such redemption was not required to be made, and the Trustee or
Paying Agent for the Securities otherwise to have been redeemed shall promptly
return to the Holders thereof any of such Securities that had been surrendered
for payment upon such redemption.

      (d) Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company, subject to paragraph (c)
of this Section, and shall be irrevocable. The notice if mailed in the manner
provided above shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice. In any case, a 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.

Section 11.5.  Deposit of Redemption Price.

      Prior to 10:00 a.m., New York City time, on any Redemption Date, the
Company shall deposit with the Trustee or with one or more Paying Agents (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and accrued interest on, all the Securities (or portions thereof) that
are to be redeemed on that date.

                                      -72-
<PAGE>

Section 11.6.  Payment of Securities Called for Redemption.

      (a) Except as provided in Section 11.4(c), after notice of redemption has
been given, the Securities to be redeemed shall become due and payable on the
Redemption Date at the place or places stated in such notice at the Redemption
Price, together with accrued interest to the Redemption Date. Upon surrender of
such Securities at a Place of Payment specified in such notice, such Securities
shall be paid and redeemed by the Company at the Redemption Price, together with
accrued interest to the Redemption Date; provided, that, unless otherwise
specified as contemplated by Section 3.1, installments of interest whose Stated
Maturity is on or prior to the Redemption Date will be payable to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 3.8.

      (b) If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal of and any premium on and
Additional Amounts with respect to such Security shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

Section 11.7.  Securities Redeemed In Part.

      Upon presentation of any Security redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder thereof, at
the expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unredeemed
portion of the Security so presented and having the same Original Issue Date,
Stated Maturity and terms.

                                  ARTICLE XII

                                 Sinking Funds

Section 12.1.  Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities. The minimum amount of any
sinking fund payment provided for by the terms of any Securities of any series
is herein referred to as a "mandatory sinking fund payment", and any sinking
fund payment in excess of such minimum amount that is permitted to be made by
the terms of such Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of any Securities of any
series, the cash amount of any sinking fund

                                      -73-
<PAGE>

payment may be subject to reduction as provided in Section 12.2. Each sinking
fund payment shall be applied to the redemption of Securities of any series as
provided for by the terms of such Securities.

Section 12.2.  Satisfaction of Sinking Fund Payments with Securities.

      In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Securities of a series in cash, the Company may at its option, at
any time no more than 16 months and no less than 60 days prior to the date on
which such sinking fund payment is due, deliver to the Trustee Securities of
such series theretofore purchased or otherwise acquired by the Company, except
Securities of such series that have been redeemed through the application of
mandatory or optional sinking fund payments pursuant to the terms of the
Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value; provided, that the Securities to be so credited have not
been previously so credited. The Securities to be so credited shall be received
and credited for such purpose by the Trustee at the Redemption Price for such
Securities, as specified in the Securities so to be redeemed, for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

Section 12.3.  Redemption of Securities for Sinking Fund.

      (a) Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, that is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and stating the basis for such
credit and that such Securities have not been previously so credited, and will
also deliver to the Trustee any Securities to be so delivered. Such Officers'
Certificate shall be irrevocable and upon its delivery the Company shall be
obligated to make the cash payment or payments therein referred to, if any, on
or before the succeeding sinking fund payment date. In the case of the failure
of the Company to deliver such Officers' Certificate (or, as required by this
Indenture, the Securities specified in such Officers' Certificate) by the due
date therefor, the sinking fund payment due on the succeeding sinking fund
payment date for such series shall be paid entirely in cash and shall be
sufficient to redeem the principal amount of the Securities of such series
subject to a mandatory sinking fund payment without the right to deliver or
credit securities as provided in Section 12.2

                                      -74-
<PAGE>

and without the right to make the optional sinking fund payment with respect to
such series at such time.

      (b) Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect
to the sinking fund. Any sinking fund moneys not so applied or allocated by the
Trustee (or, if the Company is acting as its own Paying Agent, segregated and
held in trust by the Company as provided in Section 10.3) for such series and
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 12.3. Any and all sinking fund
moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 10.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity. The Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.3 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 11.4. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Section 11.6. On or before each sinking fund
payment date, the Company shall pay to the Trustee (or, if the Company is acting
as its own Paying Agent, segregate and hold in trust as provided in Section
10.3) in cash a sum in the currency in which Securities of such series are
payable (except as provided pursuant to Section 3.1) equal to the principal and
any premium and interest accrued to the Redemption Date for Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 12.3 and any Additional Amounts with respect thereto.

      (c) Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company, if the
Company is then acting as its own Paying Agent)

                                      -75-
<PAGE>

shall redeem such Securities if cash sufficient for that purpose shall be
deposited with the Trustee (or segregated by the Company) for that purpose in
accordance with the terms of this Article. Except as aforesaid, any moneys in
the sinking fund for such series at the time when any such default or Event of
Default shall occur and any moneys thereafter paid into such sinking fund shall,
during the continuance of such default or Event of Default, be held as security
for the payment of the Securities of such series; provided, that in case such
default or Event of Default shall have been cured or waived herein, such moneys
shall thereafter be applied on the next sinking fund payment date for the
Securities of such series on which such moneys may be applied pursuant to the
provisions of this Section 12.3.

                                 ARTICLE XIII

                      Defeasance and Covenant Defeasance

Section 13.1.  Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may elect, at its option at any time, to have Section 13.2 or
Section 13.3 applied to any Securities or any series of Securities designated

Section 13.3.  Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (a)
the Company shall be released from its obligations under Sections 8.1, 10.8 and

Securities shall be unaffected thereby. Notwithstanding anything herein to the

   the following payments, specifically pledged as security for, and dedicated
   solely to, the benefit of the Holders of such Securities, (i) money in an
   amount or (ii) Government Obligations which through the scheduled payment of
   principal and interest in respect thereof in accordance with their terms will

   opinion of a nationally recognized firm of independent public accountants

   Company has received from, or there has been published by, the Internal
   Revenue Service a ruling or (ii) since the date of this instrument, there has
   been a change in the applicable Federal income tax law, in either case (i) or
   (ii) to the effect that, and based thereon such opinion shall confirm that,
   the Holders of such Securities will not recognize income, gain or loss for
   Federal income tax purposes as a result of the deposit, Defeasance and
   discharge to be effected with respect to such Securities and will be subject
   to Federal income tax on the same amounts, in the same manner and at the same
   times as would be the case if such deposit, Defeasance and discharge were not
   to occur.

      (c) In the event of an election to have Section 13.3 apply to any
   Securities or any series of Securities, as the case may be, the Company shall
   have delivered to the Trustee an Opinion of Counsel to the effect that the
   Holders of such Securities will not recognize gain or loss for Federal income
   tax purposes as a result of the deposit and Covenant Defeasance to be
   effected with respect to such Securities and will be subject to Federal
   income tax on the same amounts, in the same manner and at the same times as
   would be the case if such deposit and Covenant Defeasance were not to occur.

      (d) The Company shall have delivered to the Trustee an Officers'
   Certificate to the effect that neither such Securities nor any other
   Securities of the same series, if then listed on any securities exchange,
   will be delisted as a result of such deposit.

   90th day).

   have a conflicting interest within the meaning of the Trust Indenture Act
   (assuming all Securities are in default within the meaning of such Act).

<PAGE>

      (g) Such Defeasance or Covenant Defeasance shall not result in the trust
   arising from such deposit constituting an investment company within the
   meaning of the Investment Company Act unless such trust shall be registered
   under such Act or exempt from registration thereunder.

      (h) If the money and/or Government Obligations deposited in trust pursuant
   to this Section are sufficient to pay and discharge such Securities on a
   Redemption Date, then at or prior to the time of such deposit, either notice
   of such redemption shall have been given in accordance with Section 11.4 or
   the Company shall have irrevocably instructed the Trustee to give such notice
   of redemption and arrangements satisfactory to the Trustee for the giving of
   such notice by the Trustee in the name, and at the expense, of the Company
   shall have been made.

money and Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 13.6, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 13.4 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium, interest and Additional Amounts, but money so held in trust
need not be segregated from other funds except to the extent required by law.

      (b) The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 13.4 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

      (c) Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon a Company Request any
money or Government Obligations held by it as provided in Section 13.4 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered

                                      -79-

to be deposited to effect the Defeasance or Covenant Defeasance, as the case may
be, with respect to such Securities.

Section 13.6.  Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 13.2 or 13.3 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 13.5 with respect to such Securities
in accordance with this Article; provided, that if the Company makes any payment
of principal of, any premium or interest on or any Additional Amounts with
respect to any such Security following such reinstatement of its obligations,
the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

Section 13.7.  Qualifying Trustee.

      Any trustee appointed pursuant to Section 13.4 for the purpose of holding
trust funds deposited pursuant to that Section shall be appointed under an
agreement in form reasonably acceptable to the Trustee and shall provide to the
Trustee a certificate of such trustee, upon which certificate the Trustee shall
be entitled to conclusively rely, that all conditions precedent provided for
herein to the related Defeasance or Covenant Defeasance have been complied with.
In no event shall the Trustee be liable for any acts or omissions of said
trustee.

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