Redemption Provisions:

The Secured Medium-Term Notes, Series N offered hereby (the “Secured Medium-Term Notes”) will be subject to redemption as described in the prospectus and prospectus supplement.

Additionally, the Secured Medium-Term Notes will be subject to redemption at any time prior to February 1, 2050 (the date that is six months prior to the Maturity Date) (the “Make Whole Redemption Period”) on not less than 30 days’ prior written notice to holders, either as a whole or in part, at the option of PSE&G, at a redemption price equal to the greater of (i) 100% of the principal amount of the Secured Medium-Term Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest that would be due if such Secured Medium-Term Notes matured on February 1, 2050 (exclusive of accrued interest to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus          basis points (        %), plus, in either case, accrued interest thereon to the date of redemption.

At any time on or after February 1, 2050 (the date that is six months prior to the Maturity Date), the Secured Medium-Term Notes will be subject to redemption on not less than 30 days’ prior written notice to holders, either as a whole or in part, at the option of PSE&G, at a redemption price equal to 100% of the principal amount of the Secured Medium-Term Notes to be redeemed, plus accrued interest thereon to the date of redemption.

“Treasury Rate” means, with respect to any redemption date during the Make Whole Redemption Period, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Secured Medium-Term Notes to be redeemed (assuming that the Secured Medium-Term Notes matured on February 1, 2050) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to such remaining term of the Secured Medium-Term Notes to be redeemed.

“Comparable Treasury Price” means, with respect to any redemption date during the Make Whole Redemption Period, (i) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of five Reference Treasury Dealer Quotations, or (ii) if the Trustee is unable to obtain five Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so obtained.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by PSE&G and acceptable to the Trustee.

“Reference Treasury Dealer” means a primary U.S. Government Securities Dealer in the United States (a “Primary Treasury Dealer”) selected by PSE&G and acceptable to the Trustee.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date during the Make Whole Redemption Period, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at or before 5:00 p.m., New York City time, on the third business day preceding such redemption date.
