     Section 4A.03.  Redemption of Notes upon a Mandatory

and the rights of the Holders resulting therefrom and shall
state:

          (a)   The Repurchase Date;
          (b)   the Repurchase Price;
          (c)   the place or places where such Notes are to be
                surrendered for payment of the Repurchase Price;
                and
          (d)   in the case of a Put Event:

             (1)  the date by which Notes are to be surrendered
                  in order to be repurchased;
             (2)  a description of the procedure which a Holder
                  must follow to exercise a Put Right; and
             (3)  that exercise of the option to elect
                  redemption is irrevocable.

     At the Corporation's request, the Trustee shall give notice
of the Repurchase Date in the Corporation's name and at its
expense.

     No failure of the Corporation to give the foregoing notice
shall limit any Holder's right to exercise a Put Right or to
have such Holder's Notes redeemed following a Mandatory
Repurchase Event.

     Section 4A.06.  Deposit of Repurchase Price.  By the
Repurchase Date, the Corporation shall deposit with the Paying
Agent an amount of money sufficient to pay the Repurchase Price
of the Notes which are to be redeemed on that date.  Principal
and interest on the Notes to be redeemed shall be considered paid
on the Repurchase Date if the Trustee or any Paying Agent holds
on the Repurchase Date money sufficient to pay all principal and
interest then due.

     Section 4A.07.  Exercise of Put Right by Holder.  To
exercise the Put Right set forth in Section 4A.02, the Holder of
such Notes must deliver at least thirty days prior to the
applicable Repurchase Date the Exercise Notice to the Trustee
together with the Notes with respect to which the Put Right is
being exercised, duly endorsed for transfer.  If any Note so
delivered is, at the option of the Holder, to be redeemed only in
part, such Exercise Notice from the Holder shall state the
principal amount of the Note which is to be redeemed.  The
written notice given by any Holder pursuant to this Section 4A.07
shall be irrevocable.

     If the Notes are in the form of a Global Security at the
time a Put Right is exercised, the Exercise Notice may be made by
delivering such notice to the Depository, in the case of a
Participant which is the Beneficial Owner of an interest in such
Global Security, or to the Participant through whom the
Beneficial Owner owns such interest, in form satisfactory to the
Participant, in either case in sufficient time for the Exercise
Notice to be delivered to the Depository (in the case of a
Beneficial Owner which is not a Participant) and by the
Depository to the Trustee.  The Exercise Notice shall specify
the principal amount of the interest in the Global Security to
be redeemed.  An Exercise Notice in form satisfactory to a
Participant, together with certification by the Participant that
it holds the interest on behalf of the Person giving the Exercise
Notice, shall be provided to the Depository by a Participant and
the Depository will forward the Exercise Notice to the Trustee. 
Exercise Notices shall be in form satisfactory to the Trustee. 
The Company will have no obligation to redeem an interest in the
Global Security as to which the Exercise Notice is not delivered
to the Trustee by the Depository at least thirty days prior to
the applicable Repurchase Date.

     Section 4A.08.  Notes Payable on Repurchase Date.  The Notes
so to be redeemed shall, on the applicable Repurchase Date,
become due and payable at the Repurchase Price applicable thereto
and from and after such date (unless the Corporation shall
default in the payment of the Repurchase Price) such Notes shall
cease to bear interest.  Upon surrender of any such Note for
redemption, such Note shall be paid by the Corporation at the
Repurchase Price, provided, however, that installments of
interest payable on or prior to such Repurchase Date shall be
payable to the Holders of such Notes registered as such at the
close of business on the relevant record date for payment of such
interest according to their terms.  If any Notes shall not be
paid upon surrender thereof for redemption, the principal shall,
until paid, bear interest from the Repurchase Date at the rate
prescribed therefor in such Notes.

     Section 4A.09.  Notes Redeemed in Part.  In the case of a
Put Event, any Note which at the option of the Beneficial Owner
is to be redeemed only in part shall be surrendered to the
Trustee (with, if the Corporation or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form
satisfactory to the Corporation and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing),
and the Corporation shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Note without
service charge, a new Note or Notes, of any authorized
denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the
principal of the Note so surrendered.

     Section 4A.10.  Substitute Rating Agency.  Should either S&P
or Moody's or both cease to rate the Notes, the Corporation
shall, as soon as practicable but in any event not more than 60
days thereafter, obtain a rating for the Notes by another Rating
Agency.

          Section 3. Confirmation of 1993 Indenture.  All the
terms, covenants, and conditions of the 1993 Indenture, as
amended hereby, are hereby in all respects ratified and
confirmed, and the 1993 Indenture as so amended shall continue in
full force and effect.
