---

 



         Section 1.05  GLOBAL SECURITIES.  The Company and Trustee hereby amend

Article II of the Original Indenture pursuant to Section 9.01(c) of the Original

Indenture to insert a new Section 2.11 at the end of Article II which reads as

follows:



 

                                     -3-



         "Section 2.11  (a)  If the Company shall establish pursuant to Section

    2.01 that the Securities of a particular series are to be issued as a

    Global Security, then the Company shall execute and the Trustee shall, in

    accordance with Section 2.04, authenticate and deliver, a Global Security

    which (i) shall represent, and shall be denominated in an amount equal to

    the aggregate principal amount of, all of the Outstanding Securities of

    such series, (ii) shall be registered in the name of the Depository or its

    nominee, (iii) shall be delivered by the Trustee to the Depository or

    pursuant to the Depository's written instruction or (if acceptable to the

    Trustee) held by the Trustee as custodian for the Depository, and (iv)

    shall bear a legend substantially to the following effect:  'Except as

    otherwise provided in Section 2.11 of the Indenture, this Security may be

    transferred, in whole but not in part, only to another nominee of the

    Depository or to a successor Depository or to a nominee of such successor

    Depository'.



         (b)  Notwithstanding the provisions of Section 2.05, the Global

    Security of a series may be transferred, in whole but not in part and in

    the manner provided in Section 2.05, only to another nominee of the

    Depository for such series, or to a successor Depository for such series

    selected or approved by the Company or to a nominee of such successor

    Depository.



         (c)  If at any time the Depository for a series of Securities notifies

    the Company that it is unwilling or unable to continue as Depository for

    such series or if at any time the Depository for such series shall no

    longer be registered or in good standing under the Securities Exchange Act

    of 1934, as amended, or other applicable statute or regulation and a

    successor Depository for such series is not appointed by the Company within

    90 days after the Company receives such notice or becomes aware of such

    condition, as the case may be, this Section 2.11 shall no longer be

    applicable to the Securities of such series and the Company will execute,

    and subject to Section 2.05, the Trustee will authenticate and deliver,

---

 

    Securities of such series in definitive registered form without coupons, in

    authorized denominations, and in an aggregate principal amount equal to the

    principal amount of the Global Security of such series in exchange for such

    Global Securities.  In addition, the Company may at any time determine that

    the Securities of any series shall no longer be represented by a Global

    Security and that the provisions of this Section 2.11 shall no longer apply

    to the Securities of such series. In such event the Company will execute

    and subject to Section 2.05, the Trustee, upon receipt of an Officers'

    Certificate evidencing such determination by the Company, will authenticate

    and deliver Securities of such series in definitive registered form without

    coupons, in authorized denominations, and in an aggregate principal amount

    equal to the principal amount of the Global Security of such series in

    exchange for such Global Security. Upon the exchange of the Global Security

    for such Securities in definitive registered form without coupons, in

    authorized denominations, the Global Security shall be canceled by the

    Trustee. Such Securities in definitive registered form issued in exchange

    for the Global Security pursuant to this Section 2.11(c) shall be

    registered in such names and in such authorized denominations as the



 

                                     -4-



    Depository, pursuant to instructions from its direct or indirect

    participants or otherwise, shall instruct the Trustee. The Trustee shall

    deliver such Securities to the Depository for delivery to the persons in

    whose names such Securities are so registered."



    Section 1.06  NOTICE OF DEFAULT.  The Company and Trustee hereby amend the

first paragraph of Section 6.07 of the Original Indenture in its entirety,

pursuant to Section 9.01(c) of the Original Indenture for the benefit of all

Securityholders, to read as follows:



    "The Trustee shall, within 90 days after the occurrence of a default with

    respect to a particular series, transmit by mail, first class postage

    prepaid, to the holders of Securities of that series, as their names and

    addresses appear upon the Security Register, notice of all defaults with

    respect to that series known to the Trustee, unless such defaults shall

    have been cured before the giving of such notice (the term "defaults" for

    the purposes of this Section being hereby defined to be the events

    specified in subsections (1), (2), (3), (4) and (5) of Section 6.01(a), not

    including any periods of grace provided for therein and irrespective of the

    giving of notice provided for by subsection (3) of Section 6.01(a);

---

 

    provided, that, except in the case of default in the payment of the

    principal of (or premium, if any) or interest on any of the Securities of

    that series or in the payment of any sinking fund or analogous fund

    installment established with respect to that series, the Trustee shall be

    protected in withholding such notice if and so long as the board of

    directors, the executive committee, or a trust committee of directors

    and/or responsible officers, of the Trustee in good faith determine that

    the withholding of such notice is in the interests of the Securityholders

    of Securities of that series; provided further, that in the case of any

    default of the character specified in Section 6.01(a)(3) with respect to

    Securities of that series no notice shall be given until at least 30 days

    after the occurrence thereof."
