NEW EWG PROJECTS IN WHICH XCEL ENERGY INVESTED OR COMMITTED TO INVEST DURING THE FIRST QUARTER: In March 2002, Xcel Energy commenced an exchange offer under which Xcel Energy would acquire all of the publicly held outstanding common stock of NRG. Xcel Energy currently owns 74 percent of NRG's outstanding common stock and class A common stock, representing 97 percent of the total voting power of such stock. Under the offer terms, each of NRG's public stockholders would receive 0.50 of a share of Xcel Energy common stock in a tax-free exchange for each outstanding share of NRG common stock they hold. 2 Completion of the offer is conditioned on NRG's public shareholders tendering enough shares so that, when taken together with the shares of common stock that Xcel Energy would hold upon conversion of its Class A shares, Xcel Energy would own at least 90 percent of NRG's common stock. Xcel Energy must also receive approval of the SEC under the Public Utility Holding Company Act. At a meeting on May 29, 2002, the Securities and Exchange Commission approved the offer, subject to receipt of an updated fairness opinion. In February 2002, NRG issued to Xcel Energy a $300-million subordinated convertible note. Xcel Energy, at its option, may cause NRG to convert the note into an aggregate number of shares of NRG's common stock equal to the sum of the then outstanding principal amount of the note and all accrued but unpaid interest divided by the price per share on the date specified in the notice to convert. Xcel Energy will cancel this debt if the exchange offer is completed, thereby effectively making a capital contribution to NRG. If the exchange offer is not completed, Xcel Energy intends to convert the note into NRG common stock. Also during the first quarter of 2002, Xcel Energy, through Xcel Energy Argentina Inc., contributed an additional $3.2 million to Corporacion Independiente de Energia S. A., a wholly-owned subsidiary of Xcel Energy Argentina, to provide financing to pay off outstanding debt and for general corporate purposes. F.)
