The Company and the Trustees may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustees shall be affected by any notice to the contrary.

The Trustees may conclusively presume that the obligation of the Company to pay the principal of and interest on the bonds of this series as the same shall become due and payable shall have been fully satisfied and discharged unless and until the Corporate Trustee shall have received a written notice (which may be a facsimile followed by a hard copy) from the Trust Indenture Trustee, signed by its President, a Vice President or a Trust Officer, stating that the corresponding payment of principal of or interest on the Series 2006 Bonds has become due and payable and has not been fully paid and specifying the amount of funds required to make such payment.

Said notice shall also contain a waiver of notice under the Mortgage of such redemption by the Trust Indenture Trustee, as the holder of all the bonds of this series then Outstanding.

No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

This bond shall be construed in accordance with and governed by the laws of the State of New York.

(II) The bonds of the Seventy-third Series shall be issued in the aggregate principal amount of $56,378,000 and delivered to, and registered in the name of and held by, Simmons First Trust Company, National Association (hereinafter the "Trust Indenture Trustee"), the trustee under the Trust Indenture, dated as of June 1, 2006 (the "Trust Indenture") between Jefferson County, Arkansas (the "Issuer"), the issuer of the Pollution Control Revenue Refunding Bonds (Entergy Arkansas, Inc. Project) Series 2006 (hereinafter the "Series 2006 Bonds"), in order to evidence in part the Company's obligation to make certain payments under the Loan Agreement dated as of June 1, 2006, between the Issuer and the Company.

The obligation of the Company to make any payment of principal of or interest on the bonds of the Seventy-third Series, whether at maturity, upon redemption or otherwise, shall be reduced by the amount of any reduction under the Trust Indenture of the amount of the corresponding payment required to be made by the Issuer thereunder in respect of the principal of or interest on the Series 2006 Bonds. The Trustees may conclusively presume that the obligation of the Company to pay the principal of or interest on the bonds of the Seventy-third Series as the same shall become due and payable shall have been fully satisfied and discharged unless and until the Corporate Trustee shall have received a written notice (which may be a facsimile followed by a hard copy) from the Trust Indenture Trustee, signed by its President, a Vice President or a Trust Officer, stating that the corresponding payment of principal of or interest on the Series 2006 Bonds has become due and payable and has not been fully paid and specifying the amount of funds required to make such payment.

A default by the Issuer in the performance or observance of any covenants, agreements or conditions (other than payment covenants) in the Trust Indenture or the Series 2006 Bonds will not result in an obligation of the Company to redeem the bonds of the Seventy-third Series.

In the event that any Series 2006 Bonds are to be redeemed pursuant to Article III of the Trust Indenture, bonds of the Seventy-third Series, in a principal amount equal, as nearly as practicable, to the sum of (i) the principal amount of such Series 2006 Bonds being redeemed and (ii) eight-twelfths (8/12) of the annual interest due on such Series 2006 Bonds being redeemed, shall be redeemed by the Company, on the date fixed for redemption of such Series 2006 Bonds, at a redemption price of 100% of the principal amount thereof.

The Trustees may conclusively presume that no redemption of bonds of the Seventy-third Series is required pursuant to this subsection (III) unless and until the Corporate Trustee shall have received a written notice (which may be a facsimile followed by a hard copy) from the Trust Indenture Trustee signed by its President, a Vice President or a Trust Officer, stating that the Series 2006 Bonds have become immediately due and payable pursuant to Section 8.02 of the Trust Indenture upon the occurrence of an Event of Default under Section 8.01 (a), (b) or (d) of the Trust Indenture, or that the Series 2006 Bonds (or any portion thereof) are to be redeemed pursuant to Article III of the Trust Indenture and specifying the date fixed for the redemption and the principal amount thereof. Said notice shall also contain a waiver of notice under the Mortgage of such redemption by the Trust Indenture Trustee, as the holder of all the bonds of the Seventy-third Series then Outstanding.

(IV) The Company hereby waives its right to have any notice of redemption pursuant to subsection (III) of this Section 1 state that such notice is subject to the receipt of the redemption moneys by the Corporate Trustee before the date fixed for redemption. Notwithstanding the provisions of Section 52 of the Mortgage, any such notice under such Section shall not be conditional

(V) At the option of the registered owner, any bonds of the Seventy-third 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 of other authorized denominations.

Bonds of the Seventy-third Series shall not be transferable except to any successor trustee under the Trust Indenture, and any such transfer shall be made (subject to the provisions of Section 12 of the Mortgage) at the office or agency of the Company in the Borough of Manhattan, The City of New York.

The Company hereby waives any right to make a charge for any exchange or transfer of bonds of the Seventy-third Series.
