          The interest rates applied to Money Pool borrowings and investments during the Quarter are set forth in Exhibit 1 hereto, which is incorporated herein by reference.

5. GUARANTEES

          During the Quarter, National issued ten guarantees on behalf of NFR, in the following amounts: $10,000,000, $2,000,000, $3,000,000, $1,000,000, $8,000,000, $67,000,000, $500,000, $3,500,000, $15,000,000 and $8,000,000.

           National also issued two guarantees on behalf of Horizon Power, in the amounts of $2,716,362 and $2,070,391.

          The maximum amount of guarantees and credit support that National had outstanding on behalf of its Subsidiaries at any time during the Quarter was $517,872,753. The guarantees and credit support relate primarily to: (i) obligations under derivative financial instruments, which are included on the consolidated balance sheet in accordance with Statement of Financial Accounting Standards No. 133; (ii) Distribution Corporation obligations to purchase gas to be resold in its regulated business in accordance with established regulatory mechanisms to pass through the cost of that gas to its retail customers; (iii) NFR or Upstate obligations to purchase gas or to purchase gas transportation/storage services where the amounts due on those obligations each month are included on National's consolidated balance sheet as a current liability; and (iv) other obligations which are reflected on National's consolidated balance sheet. National believes that the likelihood it would be required to make payments under the guarantees is remote.

6. HEDGING TRANSACTIONS

          During the Quarter, National did not enter into any Interest Rate Hedges or Anticipatory Hedges.

7. CHANGES IN CAPITAL STRUCTURE OF MAJORITY-OWNED NONUTILITY SUBSIDIARIES

          During the Quarter, Horizon Energy Development, s.r.o., one of the lower-tier subsidiaries of Horizon Energy Development, Inc., in accordance with the authorization of the relevant Czech regulatory authority, reduced its stated capital by approximately $1.5 million, which funds were ultimately remitted to Horizon Energy Development, Inc.

8. NONUTILITY SUBSIDIARY REORGANIZATIONS

          During the Quarter, Highland was reorganized as a New York corporation (it was formerly a Pennsylvania corporation), and Seneca contributed to Highland certain rights to timber assets in exchange for stock of Highland.

9. OTHER ITEMS

          National filed a Form U-6B-2 on February 28, 2003.

          National's consolidated balance sheet as of March 31, 2003 is included in National's Form 10-Q filed with the Commission on May 15, 2003 and incorporated herein by reference.

          Distribution Corporation's balance sheet as of March 31, 2003 is set forth in Exhibit 2 hereto, which is incorporated herein by reference and filed confidentially pursuant to Rule 104(b).
