The Company further covenants and agrees to and with the Trustee and its successors in said trust under the Indenture, as follows:

ARTICLE I.

Eightieth Series of Bonds

SECTION 1.There shall be a series of bonds designated "First Mortgage Bonds, 4.70% Pollution Control Series due 2029" (herein sometimes referred to as the "Eightieth Series"), each of which shall also bear the descriptive title First Mortgage Bonds, and the form thereof, which shall be established by Resolution of the Board of Directors of the Company, shall contain suitable provisions with respect to the matters hereinafter in this Section specified. Bonds of the Eightieth Series shall be limited to $115,500,000 in aggregate principal amount, except as provided in Section 16 of the Mortgage, and shall be issued as fully registered bonds in denominations of One Thousand Dollars and in any multiple or multiples of One Thousand Dollars; each bond of the Eightieth Series shall mature on September 1, 2029, shall bear interest at the rate of 4.70% per annum, payable semi-annually on March 1 and September 1 of each year; the principal of and interest on each said bond to be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, and interest on each said bond to be also payable at the office of the Company in the City of Allentown, Pennsylvania, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts. Bonds of the Eightieth Series shall be dated as in Section 10 of the Mortgage provided.

The bonds of the Eightieth Series shall be issued by the Company, registered in the name of and delivered to JPMorgan Chase Bank, N.A., as trustee (the "2001 Trustee") under an Indenture dated as of August 1, 2001 (the "2001 Indenture"), to provide for the payment when due (whether at maturity, by acceleration or otherwise) of the principal and interest of the Securities (as defined in the 2001 Indenture) to be issued from time to time under the 2001 Indenture.

The bonds of the Eightieth Series shall not be transferable by the 2001 Trustee, except to a successor trustee under the 2001 Indenture. Bonds of the Eightieth Series so transferable to a successor trustee under the 2001 Indenture may be transferred at the principal office of the Trustee in the Borough of Manhattan, The City of New York.

Any payment by the Company under the 2001 Indenture of the principal of or premium, if any, or interest, if any on the securities (the "4.70% Securities") which shall been authenticated and delivered under the 2001 Indenture on the basis of the issuance and delivery to the 2001 Trustee of bonds of the Eightieth Series (other than by the application of the proceeds of a payment in respect of such bonds) shall, to the extent hereof, be deemed to satisfy and discharge the obligation of the Company, if any, to make a payment of principal of, or premium, or interest on such bonds, as the case may be, which is then due.

The Trustee may conclusively presume that the obligation of the Company to pay the principal of or interest on the bonds of the Eightieth Series as the same shall become due and payable shall have been fully satisfied and discharged unless and until it shall have received a written notice from the 2001 Trustee, signed by an authorized officer thereof, stating that the principal of or interest on specified bonds of the Eightieth Series has become due and payable and has not been fully paid, and specifying the amount of funds required to make such payment.

(I) Each holder of a bond of the Eightieth Series consents that the bonds of the Eightieth Series may be redeemable at the option of the Company or pursuant to the requirements of the Mortgage in whole at any time, or in part from time to time, prior to maturity, without notice provided in Section 52 of the Mortgage, at the principal amount of the bonds to be redeemed, in each case, together with accrued interest to the date fixed for redemption by the Company in a notice delivered on or before the date fixed for redemption by the Company to the Trustee and to the holders of the bonds to be redeemed.

(II) The bonds of the Eightieth Series shall also be redeemable, in whole at any time, or in part from time to time, prior to maturity, at a redemption price equal to the principal amount thereof, together with accrued and unpaid interest to the date of payment of such principal amount, upon receipt by the Trustee of a written notice from the 2001 Trustee (i) delivered to the Trustee and the Company, (ii) signed by its President or any Vice President, (iii)(A) stating that an Event of Default has occurred under the 2001 Indenture and is continuing and that, as a result, there then is due and payable a specified amount with respect to the Securities Outstanding under the 2001 Indenture, for the payment of which the 2001 Trustee has not received funds or (B) stating that the 4.70% Securities have become due and payable pursuant to the mandatory redemption provisions therein and in the 2001 Indenture, and the 2001 Indenture Trustee has not received funds for such payment, and (iv) specifying the principal amount of the bonds of the Eightieth Series to be redeemed. Delivery of such notice shall constitute a waiver by the 2001 Trustee of notice of redemption under the Indenture.

(III) At the option of the registered owner, any bonds of the Eightieth Series, upon surrender thereof, for cancellation, at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series, interest rate, maturity and other terms of other authorized denominations.

Subject to the provisions of the third paragraph of this Section 1, Bonds of the Eightieth Series shall be transferable, upon the surrender thereof for cancellation, together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York; provided that such transfer shall not result in any security being required to be registered under the Securities Act of 1933, as amended, and an opinion of counsel satisfactory to the Company to such effect shall have been provided to the Company.

The bonds of the Eightieth Series shall not be redeemable by the application of cash deposited with the Trustee pursuant to the provisions of Section 64.

Upon any transfer or exchange of bonds of the Eightieth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge, as provided in Section 12 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Eightieth Series.
