the Authority to the Authority Trustee, and the Bonds have been delivered by the
Company on behalf of the Authority directly to the Authority Trustee, as
assignee, as security for the payment of the principal of, and premium, if any,

                  In the event any Authority Bonds shall be purchased by the
Company and cancelled pursuant to the Authority Indenture, Bonds corresponding

deemed to be paid in full, and in the event and to the extent the principal of,

principal amount of Bonds shall be deemed to have been satisfied.

                  In the event this Bond shall be deemed to have been paid in
full, this Bond shall be surrendered to the Trustee for cancellation. In the
event this Bond shall be deemed to have been paid in part, this Bond shall be
presented to the Trustee for notation hereon of the payment of the portion of
the principal hereof so deemed to have been paid.

                                       14


                  The Bonds are redeemable only as follows:

         (e) The Bonds are subject to redemption prior to maturity, at the
option of the Company, on or after November 1, 2015, in whole or in part, at a

plus interest accrued thereon to the date fixed for redemption.

         (f) The Bonds are also subject to redemption at the direction of the
Company, in whole, at any time prior to maturity, at a redemption price of 100%

thereon to the date fixed for redemption, at any time the Authority Series A
Bonds are subject to extraordinary optional redemption pursuant to Section
7.01(a)(ii) of the Authority Indenture.

         (g) The Bonds are also subject to special mandatory redemption at the
direction of the Company, in part, prior to maturity, at a redemption price of
100% of the principal amount of the bonds to be redeemed, plus interest accrued
thereon to the date fixed for redemption, at such time and in such amount as the
Authority Series A Bonds are subject to special mandatory redemption pursuant to
Section 7.01(a)(iii) of the Authority Indenture.

         (h) The Bonds are also subject to mandatory redemption by the Company
in whole if the Trustee shall receive a written demand from the Authority
Trustee for redemption of all such Bonds held by the Authority Trustee stating
that an "Event of Default" as defined in Section 9.01(a) of the Authority
Indenture has occurred and is continuing and that payment of the principal of
the Authority Bonds has been accelerated pursuant to Section 9.01(b) of the
Authority Indenture, provided that at the time of notice of such redemption as
provided in Section 2 of Article V of the Original Indenture (i) said written
demand shall not have been withdrawn by the Authority Trustee, and (ii) no event
of default under Section 1 of Article XI of the Original Indenture shall have
occurred and be continuing.

                  If this Bond or any portion hereof is called for redemption
and payment thereof is duly provided for as specified in the Indenture, interest
shall cease to accrue hereon or on such portion, as the case may be, from and
after the date fixed for redemption.

                  The principal hereof may be declared or may become due prior
to its maturity date on the conditions, in the manner and with the effect set
forth in the Indenture upon the happening of an event of default, as in the
Indenture provided; subject, however, to the right, under certain circumstances,
of the registered owners of a majority in principal amount of Bonds outstanding
to annul such declaration.

person or by attorney duly authorized in writing, on books of the Company to be
kept for that purpose at the designated office of the Trustee in Philadelphia,
Pennsylvania upon surrender hereof for cancellation at such office and upon
presentation of a written instrument of transfer duly executed, and thereupon
the Company shall issue in the name of the transferee or transferees, and the
Trustee shall authenticate and deliver, a new Bond or Bonds in authorized
denominations, of equal aggregate unpaid principal amount. Any such transfer or
exchange shall be subject to the terms and conditions and to the payment of the
charges specified in the Indenture.

owner of this Bond as the absolute owner hereof for the purpose of receiving
payment of or on account of the principal hereof and the interest hereon, and
for all other purposes, and shall not be affected by any notice to the contrary.

                  No recourse shall be had for the payment of the principal of
or interest on this Bond or for any claim based hereon or otherwise in respect
hereof or of the Indenture or of any indenture supplemental thereto against any
incorporator or any past, present or future stockholder, officer or director of
the Company or of any predecessor or successor corporation, as such, either
directly or through the Company or through any such predecessor or successor
corporation or through any receiver or trustee in bankruptcy, by virtue of any
constitutional provision, statute or rule of law or equity, or by the
enforcement of any assessment or penalty or otherwise; all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released by every holder or registered owner hereof, as
more fully provided in the Indenture.

                  This Bond shall not be entitled to any benefit under the
Indenture or any indenture supplemental thereto, or become valid or obligatory
for any purpose, until J.P. Morgan Trust Company, National Association, as
Trustee under the Indenture, or a successor trustee thereunder, shall have
signed the certificate of authentication endorsed hereon.

interest payment date notwithstanding the cancellation of such Bond upon any
transfer or exchange subsequent to the Record Date and prior to such interest
payment date; provided, however, that if and to the extent the Company shall
default in the payment of the interest due on such interest payment date, such
defaulted interest shall be paid to the persons in whose names outstanding Bonds

not less than fifteen days preceding such subsequent Record Date, such Record
Date to be not less than ten days preceding the date of payment of such
defaulted interest. The term "Record Date" with respect to any regular interest
payment date shall mean the fifteenth day of the calendar month next preceding
the month in which such interest payment date occurs.
