     Summary Unaudited Consolidated Pro Forma Financial Statements.  The
following summary unaudited consolidated pro forma financial statements give
effect to the purchase of shares of Common Stock, par value $0.01 per share
("Shares"), of Conectiv, a Delaware corporation (the "Company"), pursuant to the
Company's offer to purchase 14 million Shares at a price not greater than $25.50
nor less than $23.50 per Share in cash (the "Offer"), including the related
incurrence of indebtedness, and the reduction in the dividend on the Shares,
based on certain assumptions described below and in the related Notes below. The
Summary Unaudited Consolidated Pro Forma Balance Sheets give effect to the
purchase of Shares pursuant to the Offer, including the related incurrence of
indebtedness, as though such events occurred as of the respective dates of such
balance sheets. The Summary Unaudited Consolidated Pro Forma Statements of
Income for the three-month period ended March 31, 1999 and for the year ended
December 31, 1998 give effect to the purchase of Shares pursuant to the Offer,
including the related incurrence of indebtedness, and the reduction in the
dividend on the Shares as though such events occurred on January 1, 1999 and
March 1, 1998, respectively. The summary unaudited consolidated pro forma
financial statements should be read in conjunction with the historical
consolidated financial information of the Company and does not purport to be
indicative of the operating results that would actually have been obtained, or
operating results that may be obtained in the future, or the financial position
that would have resulted had the purchase of the Shares pursuant to the Offer,
including the related incurrence of indebtedness, and the reduction in the
dividend on the Shares been completed at the dates indicated.
 
     The pro forma adjustments assume the following:
 
     (A) The issuance by the Company of $357.0 million of debt at an average
         interest rate of 7%, including (a) $250.0 million of medium term notes
         ("Notes") having an average life of 5 years, and (b) $107.0 million of
         commercial paper; and the payment by the Company of $1.7 million in
         fees and expenses relating to the issuance of the Notes.
 
     (B) The realization of an income tax benefit resulting from interest
         expense on the debt and amortization of debt issuance expenses, based
         on an effective income tax rate of 40.85%.
 
     (C) The use by the Company of proceeds from the debt issuance to purchase
         14,000,000 Shares at $25 1/2 per Share in the Offer, including Shares
         purchased as the result of the conversion of shares of Class A Common
         Stock; and the payment by the Company of $3.0 million of related Offer
         expenses.
 
     (D) The payment of dividends on Shares at $0.22 per Share per quarter, or
         $0.88 per Share per year.
 
     (E) A decrease in the number of outstanding shares of Class A Common Stock
         due to the conversion of shares of Class A Common Stock to Shares and
         purchase of Shares by the Company in the Offer, assuming each share of
         Class A Common Stock was converted to 1.59997 Shares. A reduction in
         the Class A Common Stock's percentage of earnings from the Atlantic
         Utility Group (as defined in the Company's Restated Certificate of
         Incorporation) that exceed $40.0 million per year from 30% to 27.2% is
         assumed for the three months ended March 31, 1999 and 27.3% for the
         twelve months ended December 31, 1998.
 
     (F) The number of Shares purchased from holders of Class A Common Stock who
         elect to convert shares of Class A Common Stock to Shares was assumed
         to be equal to the quotient of (a) the number of shares of Class A
         Common Stock outstanding multiplied by the Class A Common Stock
         conversion ratio, divided by (b) (i) the number of Shares outstanding
         as of the date Shares are assumed to be purchased under the Offer, and
         (ii) the number of shares of Class A Common Stock outstanding
         multiplied by the Class A Common Stock conversion ratio, multiplied by
         (c) the 14,000,000 Shares purchased in the Offer. The balance of the
         14,000,000 Shares purchased is assumed to be from holders of Shares
         other than the Shares attributed to the conversion of Class A Common
         Stock.
