NJR wishes to caution persons reading or hearing this presentation that the assumptions that form the basis for forward-looking statements regarding financial results and capital requirements for fiscal 2003 and thereafter include many factors that are beyond the Company's ability to control or estimate precisely, such as estimates of future market conditions, the behavior of other market participants and changes in the debt and equity capital markets.

Appendix: Gross Margin Gross margin is a non-GAAP measure. Gross margin is defined as gas revenues less gas purchases, sales tax and a Transitional Energy Facilities Assessment (TEFA), which is included in Energy and other taxes on the Consolidated Statements of Income. NJNG believes that gross margin provides a more meaningful basis for evaluating utility operations than does revenues since gas costs, sales tax and TEFA are passed through to customers and, therefore, have no effect on gross margin. For reconciliation to our revenue, see our periodic SEC filings available on our Web site at njliving.com
