Supplemental Information Regarding

Proposal 3: Non-Binding Advisory Vote Approving Executive Compensation

February 27, 2012

Dear Stockholders of National Fuel Gas Company:

At National Fuel Gas Company’s (the “Company”) Annual Meeting of Stockholders to be held on March 8, 2012, stockholders will cast a non-binding advisory vote to approve the compensation of the Company’s executives (the “say on pay” vote). Proposal 3 in the Company’s 2012 proxy statement includes relevant information regarding this matter, as does Supplemental Information filed on February 24, 2012. The Company’s Board of Directors has recommended that you vote FOR Proposal 3.

ISS Proxy Advisory Services (“ISS”) has recommended that its clients vote against Proposal 3 in light of what ISS claims is a “pay for performance disconnect.” The Company believes that there is a fundamental flaw in ISS’s application of its methodology to the Company. The Company has raised its concerns with ISS’s analysis, along with other important observations, in a letter to ISS posted on the Company’s investor information website accessible through a link entitled “Supplemental Proxy Material — February 24, 2012”. We urge you to consider the February 24, 2012 Supplemental Information, as well as that contained below, and vote FOR Proposal 3.

COMPENSATION IN ALIGNMENT WITH PEERS

As presented below, using a proper peer group and same fiscal year proxy data, the actual total direct compensation of the Company’s CEO is 1.06 times the median of the peer group, comparing favorably to a 1-year total shareholder return of 1.34 times the median of the peer group.

When considering compensation for our executive officers, the Compensation Committee understands the importance of credible benchmark data that properly reflects information from companies with comparable business segments and that is based on appropriate time periods. As the Company’s Exploration and Production segment increased in importance, the Committee worked with the Hay Group, a well-respected, independent compensation consultant, to develop the peer group set forth on pages 23 and 24 of the Proxy Statement, whose members participate in businesses similar to those of the Company. The following chart is the Hay Group’s analysis of CEO total direct compensation (the sum of base salary, short-term incentive and long-term incentive) derived from proxy data for fiscal 2010, the most recent year data available across the peer group.

COMPENSATION IN ALIGNMENT WITH THE INTEREST OF SHAREHOLDERS

When reviewing our summary compensation table at page 34 of the Proxy Statement we believe the following points are important in making a decision on your vote.

• Glass Lewis & Co. has recommended a Vote FOR Proposal 3.

• CEO compensation has declined from the prior year, and in 2011 ISS recommended a favorable vote on that prior year compensation.

• The Compensation Committee reviewed the results of the shareholder vote on the Say on Pay proposal from the 2011 Annual Meeting and approximately 83% of the votes cast were for approval of the Company’s compensation program. After consideration of these results, the Committee believes its approach to compensation is balanced and effective and made no fundamental changes to the program.

• Excluding the non-cash change in pension value, approximately 79% of CEO compensation is performance related.

• The Company does not provide tax “gross-ups.”

• The Company’s equity incentive plans prohibit the repricing or exchange of equity awards without shareholder approval.

• The Company requires directors, executive officers and other officers to meet stock ownership requirements. Our CEO’s ownership of Company stock exceeds that requirement by three times (i.e. he holds twelve times his base salary in Company stock).

In closing, the Company believes that its compensation policies and procedures:

• encourage a culture of pay for performance,

• are strongly aligned with both the short and long-term interests of the Company’s shareholders, and

• justify a vote by shareholders FOR the say on pay resolution.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR PROPOSAL 3.

Sincerely yours,

Paula M. Ciprich

General Counsel and Secretary
