GeoGraphy 2. history 3. strateGy 4. responsibility Drilling Pad M in Lycoming County, Pa., exemplifies the Company’s industry-leading Marcellus position and its ability to maximize production efficiencies and minimize environmental impact. For more than 100 years, National Fuel’s regulated utility and pipeline businesses have provided predictable cash flows and supported consistent dividends. A diverse portfolio of businesses enables the Company to build on its Marcellus position with pipeline expansions to move gas to major markets. The environmental benefits of clean-burning natural gas are well established, as is the Company’s commitment to the use of industry best practices across all operations. ANNUAL REPORT 2010 1 A GREAT PLACE GEOGRAPHICALLY The Marcellus shale, one of The MosT prolific and econoMical naTural gas sources in The world, has puT appalachia and naTional fuel aT The cenTer of a proMising fuTure for The naTural gas indusTry. The biggest news in the gas industry in recent years has been the development of techniques to produce natural gas from shale formations, and the biggest shale gas play is right in our front yard. The Marcellus Shale is a game changer for the industry, and for National Fuel. As of today, we are actively exploring and developing more than 745,000 prospective net acres of this substantial resource. Our acreage footprint, one of the largest in the industry, and the beneficial economics of our mineral ownership position enable us to develop this asset even when natural gas prices are low. Our favorable geography is further demonstrated by the location of our existing and growing pipeline system, literally on top of the Marcellus. This infrastructure has been constructed and renewed over decades to transport natural gas to our utility customers and to the growing markets of the Northeast, initially moving production from Appalachia and later from the Gulf of Mexico and Canada. With the rapid development of the Marcellus over the past several years, producers, including our own Seneca Resources Corporation, need pipeline capacity to deliver their gas to established and emerging markets. Our leadership in pipeline construction in the Appalachian Basin provides us with the means and experience to expand our existing network and meet the needs of many of the largest Marcellus producers to access major consuming markets on the East Coast and in Ontario, Canada. As the Marcellus evolves from an emerging to an established production zone, it will transform the Appalachian Basin into the primary source of supply for the East Coast. With the advantage of our sizable mineral position and a pipeline network located directly upstream of the largest gas markets in North America, we expect that the Marcellus will be the engine that drives National Fuel’s growth not only in 2011, but for the longer run. 1. marcellus shale As one of the largest mineral owners in Pennsylvania, the Company expects ongoing development of this resource and potentially other shales, such as the Utica. 2. location Operating since 1902, National Fuel has built a solid reputation for strong customer service and is a contributing member of the communities it serves. 3. familiarity With more than 100 years of experience in the region, combined with a reputation as a first-class operator, the Company is positioned to meet the growing requirements of energy consumers. 4. infrastructure National Fuel has the ability to grow its pipeline network throughout the Appalachian Basin, supporting the needs of many Marcellus producers and downstream markets. 11* 10 09 0 $475–545 $372 $139 545 10 09 08 0 202 21 0 545 a p pa l a c h i a n G r o w t h c a p i ta l e x p e n d i t u r e s ( $ M i l l i o n s ) m a r c e l l u s s h a l e p r o v e d r e s e r v e s B i L L i O N C U B i C F E E T E q U i vA L E N T ( B C F E ) * F o r e c a s t A t S e p t e m b e r 3 0 1,760 m i l l i o n c u b i c f e e t p e r d ay of additional National Fuel pipeline capacity planned for Appalachia during the next three years 2 NATiONAL FUEL GAS COMPANY ny pa 8–15 Tcfe is our resource potential in the appalachian basin’s prolific marcellus shale 90% growTh in production for seneca’s east division in fiscal 2010 2 2,787 Miles of interstate Gas pipelines throuGhout appalachia 1 4 728,700 natural Gas utility customers served in ny and pa 3 65 gross wells drilled in the marcellus shale in fiscal 2010 5.5 bcf of seneca’s marcellus Gas Gathered by nfG midstream ANNUAL REPORT 2010 3 A GREAT PLACE HISTORICALLY our opporTuniTies Today are The legacy of sound invesTMenT decisions Made by naTional fuel ThroughouT iTs 108-year hisTory. National Fuel is one of America’s oldest energy companies, with origins tracing back to the beginnings of commercial oil and natural gas production in Appalachia. in business for more than 100 years, we have developed significant expertise in all segments of the natural gas business. Along the way, we also acquired the portfolio of high-quality assets that distinguishes National Fuel from its peers today. Chief among those assets is our Marcellus acreage. What sets us apart from our peers, however, is the nature of our ownership rights in the Marcellus. Across our Pennsylvania acreage footprint, we own approximately 80 percent of the natural gas rights in fee title with a large portion of the remainder being held by production from our conventional wells. With fee title, we own the natural gas outright, have no lease expiration deadlines, and pay no royalties. This industry-leading mineral ownership position greatly improves our production economics, providing us with the ability to earn impressive returns, even when gas prices are as low as they were in 2010. Our pipeline assets started as small gathering systems in Appalachia, and then grew to the 2,787-mile integrated system that it is today. A century of building and operating pipelines in the “gas patch” in New York and Pennsylvania has established our reputation for engineering expertise in the challenging terrains that are typical in Appalachia and the Marcellus production fields. We are using that expertise in NFG Midstream to construct gathering systems to bring Marcellus production to demand markets. Our long history has enabled us to develop a familiarity and comfort with the regulatory landscape in New York, Pennsylvania and at the federal level, that is unmatched by our peers. Because of our experience, we are able to adeptly navigate and comply with regulatory requirements, and we maintain a healthy dialogue with our regulators, as an ordinary part of our operations. 1. experience National Fuel and its predecessor companies date back to the origins of natural gas production and service in the U.S. 2. ownership From its beginnings in Appalachia, National Fuel has acquired full ownership of mineral rights for most of its acreage. That very ownership position is the basis for perhaps the most economically beneficial Marcellus program in the industry. 3. execution National Fuel is transforming opportunities into results with an aggressive drilling program and pipeline projects, producing significant growth in its pipeline, storage and gathering businesses. 745,000 n e t a c r e s prospective for the Marcellus Shale in Pennsylvania 4 NATiONAL FUEL GAS COMPANY $1.38 $0.19 1970 1980 1990 2000 2010 a n n u a l d i v i d e n d r at e at y e a r e n d ( $ P E R S h A R E ) 80% m a r c e l l u s m i n e r a l r i G h t s owned with no royalty obligation or lease expiration across Seneca’s Pennsylvania acreage ny pa naTural gas reserves per well (BCFE) 2.5-6.3 0.01-0.30 <0.01 1825 1900s 2010 1 2 3 harT’s well commercial production of natural Gas beGan in fredonia, ny convenTional drilling nfG has been producinG natural Gas for more than a century horizonTal drilling unlockinG vast natural Gas reserves in appalachia ANNUAL REPORT 2010 5 A GREAT PLACE STRATEGICALLY our diversified business Model has a solid perforMance hisTory and provides sTable cash flows ThaT enable The coMpany To Turn opporTuniTies inTo resulTs. We have long maintained a portfolio business model that sought balance among the Company’s three largest operating segments: Exploration and Production, Pipeline and Storage, and Utility. For decades, this approach has provided the consolidated holding company with stable earnings and the flexibility to capture upside opportunities as they are presented. We will continue to operate a diversified business model going forward, but we believe that our model should evolve. it has been doing just that. Today, the Company’s regulated Utility and Pipeline and Storage segments generate nearly 50 percent of our net income. Combined with a stable, yet very significant cash flow from the Exploration and Production segment’s California oil properties, these businesses sustain our dividend and help to enable our investment strategy. The Company’s footprint in the Marcellus is not solely that of a producer, but is rather that of a producer and a significant pipeline company with a history of operations in Appalachia. Our integrated pipeline system enables us to provide an outlet for Marcellus production to reach liquid trading points on existing interstate pipelines that directly serve major northeastern markets. With plans to grow and modify our pipeline system to allow natural gas to flow northward to Canadian markets, we aim to become the preeminent transporter of Marcellus supply. As a result, most of our investment activity will be in the Marcellus, in both Exploration and Production and Pipeline and Storage. More than two-thirds of our capital expenditures are allocated to Appalachia, and this amount will only increase. Our investments to assure a safe utility system will continue, but the sizable increase allocated to our Appalachian projects, particularly in the Marcellus, will shift the balance of our diversified model. The opportunities presented by the Marcellus are among the most promising that this Company has ever experienced, and the gains achieved from those opportunities are real, and growing. 1. leadership National Fuel’s industry- leading footprint in the Marcellus will drive future growth, and the Company is committed to an aggressive, yet responsible, pace of development. 2. balance Forecasted growth in infrastructure investment, like the Covington Gathering System in Tioga County, Pa., will help maintain a balanced business model that has performed favorably for decades. 3. production mix Oil production in California delivers strong cash flow that funds a significant portion of the Company’s growing Marcellus development. 4. inteGration The Utility is an important link in National Fuel’s vertically integrated chain of natural gas assets, providing a stable foundation and support for the dividend.

Our day-to-day activities are guided by three driving principles: excellent customer service, responsible financial and environmental stewardship, and productive community involvement. As an operator of public utility systems, our legal obligation is to provide safe and adequate gas service to hundreds of thousands of customers. Beyond this obligation, we strive for excellence in customer service, reliability and safety. Our safety and customer service performance metrics are among the best in the business, and we routinely meet or exceed targets established by state regulators. in financial and regulatory affairs, National Fuel exercises and demands the highest ethical standards. Through years of experience and training, we have developed a culture of compliance that we believe is a necessary part of any responsible business. As a significant driller in the Marcellus, we are actively addressing public concerns over hydraulic fracturing. We work cooperatively with regulatory agencies and maintain industry best practices to minimize the environmental impact of our drilling program. We also work closely with municipalities and landowners in our operating areas so that we can address their needs and concerns as they arise. We believe that our efforts are effective, but we also support the establishment of reasonable state regulations to ensure that all operators observe industry best practices for the protection of water and other environmental resources. As an integral part of the communities that we serve, National Fuel recognizes the importance of charitable giving. Our Company, its Foundation and employees are proud of our record of generosity through both charitable contributions and volunteer activities in all of the places where we do business. 1. environmental National Fuel’s environmental commitment is demonstrated by Seneca’s unique project that reclaims contaminated water from an abandoned coal mine and uses it in Marcellus well completions. 2. safety & reliability The Company emphasizes safety across all of its businesses for the benefit of customers, employees and the communities in which it operates. 3. community National Fuel and its employees give to and volunteer for hundreds of charities throughout and beyond the communities it serves. >$6M d o n at e d to more than 700 charities since 2005 MULTI-WELL MARCELLUS PAD CONVENTIONAL WELL PAD 1–2 20–30 d r i l l i n G w e l l pa d s p e r 1 , 0 0 0 a c r e s d e v e l o p e d $400M s p e n t f r o m 2 0 0 6 – 2 0 1 0 on repairs, improvements and maintenance to our transmission, storage and distribution systems 8 NATiONAL FUEL GAS COMPANY coMMiTMenT site reclamation reflects sound environmental practices 1 2 3 environMenTal dedicated to minimizinG environmental impact safeTy & reliabiliTy adherinG to environmental and reGulatory standards coMMuniTy employees Generously support the communities served ANNUAL REPORT 2010 9 DEAR SHAREHOLDER i believe ThaT circuMsTances, evenTs and our uniQue aTTribuTes are converging To creaTe More opporTuniTies for naTional fuel Than aT any oTher TiMe ThaT i can reMeMber. We are A Great Place To Be right now primarily because of our significantly advantageous geographic location and the Company’s legacy of business plans undertaken with the long view. Our 745,000 net acres prospective for the most promising natural gas play in a generation, the Marcellus Shale, have come to define National Fuel in the eyes of many investors, and for good reason. Our Marcellus acreage position is among the largest in the business, and our development costs are among the lowest. This enables us to generate robust earnings even when gas prices are near historic lows, as amply demonstrated in fiscal 2010. But National Fuel is much more than its Marcellus holdings. The Company owns and operates one of the most extensive pipeline systems in northern Appalachia, with a long history of connecting local producers to northeastern markets. We are capitalizing on that advantage by expanding our system to bring Marcellus production to those same markets and others. The Marcellus is also opening new opportunities for National Fuel to deliver gas to, rather than from, southern Ontario, Canada, to serve existing and anticipated new demand. Rather than merely waiting for this to happen, we are taking steps now to be there, ready to serve those markets as they grow. We are also A Great Place To Be because we have built a tradition of excellence in retail operations, serving hundreds of thousands of customers in scores of communities across western New York and northwestern Pennsylvania. Our Utility is the foundation of National Fuel’s portfolio of assets, and it continues to deliver the kind of solid, reliable results that exemplify the benefits of our integrated business model. “our uTiliTy is The foundaTion of naTional fuel’s porTfolio of asseTs, and iT conTinues To deliver solid, reliable resulTs.” david f. smith Chairman of the Board and Chief Executive Officer 10 NATiONAL FUEL GAS COMPANY “our excepTionally sTrong balance sheeT enables us To access The capiTal we need To fund our projecTs, now and for The foreseeable fuTure.” 108 y e a r s of uninterrupted dividend payments and 40 consecutive years of increases Ambitious plans are one thing, but bringing those plans to fruition is quite another. Our exceptionally strong balance sheet enables us to access the capital we need to fund our projects, now and for the foreseeable future. This capability is the result of our diversified business portfolio and, more important, the Company’s uncompromising dedication to responsible business practices. deliverinG results in 2010, National Fuel marked its 108th year of consecutive dividend payments. increasing each year since 1971, our ongoing track record of dividends has contributed to strong long-term returns. during a year when natural gas prices were down, the Company again delivered by providing shareholders with a total return of 16 percent for the fiscal year ended September 30, 2010, handily outpacing the S&P 500 index. We recorded net income of $226 million for 2010, a significant increase over the prior year. Excluding a non-cash impairment charge taken in 2009, the drivers of this increase were growth in gas production from the Marcellus and higher prices obtained for our California oil. in addition, from 2009 to 2010, total net income from our regulated Utility segment grew 6 percent, partially offsetting temporary declines in our Pipeline and Storage segment. We also achieved impressive gains in operations. We recorded total production of 49.7 billion cubic feet equivalent (Bcfe), an increase of 17 percent over the prior year, mostly from our success in the Marcellus. The first Seneca-operated Marcellus well was brought online in November 2009 and was followed by another 13 such wells, driving overall production in the Marcellus to 7.2 Bcfe for the fiscal year. Through our highly successful 2010 drilling program, we were able to replace 445 percent of our production, bringing total proved reserves to 700 Bcfe. More impressively, Seneca’s drilling and participation in 58 gross horizontal Marcellus wells allowed us to grow reserves in the region by 182 Bcfe, which is still a mere fraction of the 8 to 15 trillion cubic feet equivalent of risked resource potential within our mineral rights in the Marcellus. executinG on our opportunities during the past several years we have executed a strategy for the efficient and responsible development of our Marcellus holdings. That strategy has yielded significant results not only in terms of income generated from successful wells, but also because each well has provided us with valuable information about the extraordinary potential of our Marcellus reserves. The 862 percent increase in our Marcellus reserves during the past year reflects our operational team’s focus on development, with Seneca ultimately becoming one of the region’s most successful operators. Our development has demonstrated the economic potential of the Marcellus not only for National Fuel, but also for the communities in which we operate. The value of Marcellus supplies will be determined by access to the right markets, and here again, we are in a very good place. The location of our pipeline projects and the ability of our employees and contractors to move projects from the drawing board to active service are recognized in the industry, and increasingly by Marcellus shippers. This has enabled us to achieve significant progress in the development of several pipeline projects to bring Marcellus production to growing markets in the Northeast, and with our Northern Access and Tioga County Extension projects, expanding markets in Ontario, Canada. ANNUAL REPORT 2010 11 i am also continually impressed by the performance of our retail operations. The Utility fits neatly into our portfolio model by providing the kind of reliable and predictable performance favored by many of our share holders, and National Fuel Resources, our energy marketing company, continues to deliver solid results as it grows its market share. Our retail operations also serve sizable markets within and adjacent to the Marcellus, contributing to the synergies of our diversified, yet integrated business model. strateGic manaGement chanGes i am pleased to report significant changes in management that took place during this past year. Ron Tanski has been elevated to the position of President and Chief Operating Officer. during his 31-year career at National Fuel, Ron has consistently brought integrity, skill and leadership to his roles across all segments of the business. Now he will be focused on our consolidated operations. Replacing Ron as Treasurer and Principal Financial Officer is dave Bauer. dave’s expertise in all aspects of finance, accounting and ratemaking has positioned him well to lead the Company’s financial strategy through this exciting period of opportunity. John Pustulka was named President of National Fuel Gas Supply Corporation. his 35-year career operating and growing the interstate pipeline business places him in a strong position to lead the Pipeline and Storage segment. Reflecting our strategic direction, Matt Cabell, President of Seneca Resources, was named Senior vice President of the Company. he will maintain his role as President of Seneca, but will also play a more critical role in framing the overall direction of the Company. “The locaTion of our pipeline projecTs and The abiliTy of our eMployees and conTracTors To Move projecTs froM The drawing board To acTive service are recognized in The indusTry, and increasingly by Marcellus shippers.” 5-y e a r t o ta l s h a r e h o l d e r r e t u r n s ( A S S U M E S d i v i d E N d R E i N v E S T M E N T ) A t S e p t e m b e r 3 0 * *Assumes $100 invested on September 30, 2005 and reinvesting of dividends. $200 $175 $150 $125 $100 NFG SIG Oil E&P Index S&P 400 Utility Index S&P 500 Index $75 05 06 07 08 09 10 12 NATiONAL FUEL GAS COMPANY “i believe ThaT we are in a good place precisely because of our value-driven invesTMenT decisions.” 77% t o ta l s h a r e h o l d e r r e t u r n for the five years ended September 30, 2010 2011 and beyond Looking ahead, we will build upon the growth experienced in 2010 by focusing our energy and investment where the opportunities are greatest. For the foreseeable future, those opportunities are in the Marcellus, for both our production and pipeline businesses. From our roots of providing safe and reliable gas utility service, we are continuing a transformation that is repositioning the balance of our diversified operations. in the past, we have looked at our three largest operating segments — Utility, Pipeline and Storage, and Exploration and Production — as being equal contributors to the Company’s earnings. As our business model evolves, the Utility will remain the solid foundation that has helped to define National Fuel for the greater part of its history. But today, i believe that we are in a good place precisely because our value-driven investment decisions have not been constrained by an inflexible adherence to any particular mix among operating segments. This past year we announced, to significant interest, that we are exploring joint venture opportunities across a broad portion of our Marcellus acreage. As of this writing the search for a suitable arrangement continues, but we are in no hurry to close a deal. For us, the point of a joint venture is not to enable our current plans — we have no difficulty meeting our capital requirements — but rather to accelerate our opportunities. As responsible stewards of our valuable assets, we will not undertake any initiative unless we are confident that it will significantly add to shareholder value over the long run. Writing about the incoming presidential administration in 2008, i expressed optimism for the adoption of a national energy policy that recognized the benefits of then-recent developments in shale gas. despite those benefits — price stability, energy security, cleaner air and an abundance of well-paying jobs — any meaningful movement toward greater promotion of natural gas has been stalled by opposition from special interests and, in the case of hydraulic fracturing, deliberate misinformation. i am hopeful that changes at the federal level and in the states will enable a more balanced and informed debate, which i am confident will lead to the adoption of policies that promote natural gas. National Fuel is a member of a small, elite group of public corporations that have operated successfully for more than a century. Our shareholders have come to expect solid, consistent performance guided by our focus on the long run. That remains my commitment. Whereas in recent years i have written much about National Fuel’s potential, and the Company’s impressive opportunities, today we are executing on that potential, and on those opportunities. For this reason, i am more optimistic than ever about the Company’s future because, for our shareholders, customers and employees, we are, indeed, A Great Place To Be.

The Company is a diversified energy company and reports financial results for four business segments. 1. The Utility segment operations are carried out by National Fuel Gas Distribution Corporation (Distribution Corporation), a New York corporation. Distribution Corporation sells natural gas or provides natural gas transportation services to approximately 728,700 customers through a local distribution system located in western New York and northwestern Pennsylvania. The principal metropolitan areas served by Distribution Corporation include Buffalo, Niagara Falls and Jamestown, New York and Erie and Sharon, Pennsylvania. 2. The Pipeline and Storage segment operations are carried out by National Fuel Gas Supply Corporation (Supply Corporation), a Pennsylvania corporation, and Empire Pipeline, Inc. (Empire), a New York corporation. Supply Corporation provides interstate natural gas transportation and storage services for affiliated and nonaffiliated companies through (i) an integrated gas pipeline system extending from southwestern Pennsylvania to the New York-Canadian border at the Niagara River and eastward to Ellisburg and Leidy, Pennsylvania, and (ii) 27 underground natural gas storage fields owned and operated by Supply Corporation as well as four other underground natural gas storage fields owned and operated jointly with other interstate gas pipeline companies. Empire, an interstate pipeline company, transports natural gas for Distribution Corpo- ration and for other utilities, large industrial customers and power producers in New York State. Empire owns the Empire Pipeline, a 157-mile pipeline that extends from the United States/Canadian border at the Niagara River near Buffalo, New York to near Syracuse, New York, and the Empire Connector, which is a 76-mile pipeline extension from near Rochester, New York to an interconnection with the unaffiliated Millennium Pipeline near Corning, New York. The Millennium Pipeline serves the New York City area. The Empire Connector was placed into service on December 10, 2008. 3. The Exploration and Production segment operations are carried out by Seneca Resources Corporation (Seneca), a Pennsylvania corporation, and by Seneca Western Minerals Corp., a Nevada corporation and an indirect, wholly owned subsidiary of Seneca. Seneca is engaged in the exploration for, and the development and purchase of, natural gas and oil reserves in California, in the Appalachian region of the United States, and in the shallow waters of the Gulf Coast region of Texas and Louisiana, including offshore areas in federal waters and some state waters. At September 30, 2010, the Company had U.S. proved developed and undeveloped reserves of 45,239 Mbbl of oil and 428,413 MMcf of natural gas. 3 4. The Energy Marketing segment operations are carried out by National Fuel Resources, Inc. (NFR), a New York corporation, which markets natural gas to industrial, wholesale, commercial, public authority and residential customers primarily in western and central New York and northwestern Pennsylvania, offering competitively priced natural gas for its customers. Financial information about each of the Company’s business segments can be found in Item 7, MD&A and also in Item 8 at Note K — Business Segment Information. The Company’s other direct wholly owned subsidiaries are not included in any of the four reported business segments and include the following active companies: (cid:129) Highland Forest Resources, Inc. (Highland), a New York corporation which, together with a division of Seneca known as its Northeast Division, markets timber from Appalachian land holdings. At September 30, 2010, the Company owned approximately 100,000 acres of timber property and managed an additional 3,424 acres of timber cutting rights; (cid:129) Horizon Energy Development, Inc. (Horizon), a New York corporation formed to engage in foreign and domestic energy projects through investments as a sole or substantial owner in various business entities. These entities include Horizon’s wholly owned subsidiary, Horizon Energy Holdings, Inc., a New York corporation, which owns 100% of Horizon Energy Development B.V. (Horizon B.V.). Horizon B.V. is a Dutch company that is in the process of winding up or selling certain power development projects in Europe; (cid:129) Horizon Power, Inc. (Horizon Power), a New York corporation which is an “exempt wholesale generator” under PUHCA 2005 and is operating landfill gas electric generation facilities; and (cid:129) National Fuel Gas Midstream Corporation (Midstream Corporation), a Pennsylvania corporation formed to build, own and operate natural gas processing and pipeline gathering facilities in the Appalachian region. No single customer, or group of customers under common control, accounted for more than 10% of the Company’s consolidated revenues in 2010. Rates and Regulation The Registrant is a holding company as defined under PUHCA 2005. PUHCA 2005 repealed PUHCA 1935, to which the Company was formerly subject, and granted the FERC and state public utility commissions access to certain books and records of companies in holding company systems. Pursuant to the FERC’s regulations under PUHCA 2005, the Company and its subsidiaries are exempt from the FERC’s books and records regulations under PUHCA 2005. The Utility segment’s rates, services and other matters are regulated by the NYPSC with respect to services provided within New York and by the PaPUC with respect to services provided within Pennsylvania. For additional discussion of the Utility segment’s rates and regulation, see Item 7, MD&A under the heading “Rate and Regulatory Matters” and Item 8 at Note A — Summary of Significant Accounting Policies (Regulatory Mechanisms) and Note C — Regulatory Matters. The Pipeline and Storage segment’s rates, services and other matters are regulated by the FERC. For additional discussion of the Pipeline and Storage segment’s rates and regulation, see Item 7, MD&A under the heading “Rate and Regulatory Matters” and Item 8 at Note A — Summary of Significant Accounting Policies (Regulatory Mechanisms) and Note C — Regulatory Matters. The discussion under Item 8 at Note C — Regulatory Matters includes a description of the regulatory assets and liabilities reflected on the Company’s Consolidated Balance Sheets in accordance with applicable account- ing standards. To the extent that the criteria set forth in such accounting standards are not met by the operations of the Utility segment or the Pipeline and Storage segment, as the case may be, the related regulatory assets and liabilities would be eliminated from the Company’s Consolidated Balance Sheets and such accounting treatment would be discontinued. 4 In addition, the Company and its subsidiaries are subject to the same federal, state and local (including foreign) regulations on various subjects, including environmental matters, to which other companies doing similar business in the same locations are subject. The Utility Segment The Utility segment contributed approximately 28.5% of the Company’s 2010 income from continuing operations and 27.7% of the Company’s 2010 net income available for common stock. Additional discussion of the Utility segment appears below in this Item 1 under the headings “Sources and Availability of Raw Materials,” “Competition: The Utility Segment” and “Seasonality,” in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data. The Pipeline and Storage Segment The Pipeline and Storage segment contributed approximately 16.7% of the Company’s 2010 income from continuing operations and 16.2% of the Company’s 2010 net income available for common stock. Supply Corporation has service agreements for all of its firm storage capacity, totaling 68,408 MDth. The Utility segment has contracted for 27,865 MDth or 40.7% of the total firm storage capacity, and the Energy Marketing segment accounts for another 4,811 MDth or 7.1% of the total firm storage capacity. Nonaffiliated customers have contracted for the remaining 35,732 MDth or 52.2% of the total firm storage capacity. The majority of Supply Corporation’s storage and transportation services are performed under contracts that allow Supply Corporation or the shipper to terminate the contract upon six or twelve months’ notice effective at the end of the contract term. The contracts also typically include “evergreen” language designed to allow the contracts to extend year-to-year at the end of the primary term. At the beginning of 2011, 88.1% of Supply Corporation’s total firm storage capacity was committed under contracts that, subject to 2010 shipper or Supply Corporation notifications, could have been terminated effective in 2011. Supply Corporation received storage contract termination notifications in 2010 totaling approximately 5,300 MDth of storage capacity. Supply Corporation expects to remarket this capacity with service beginning April 1, 2011. Supply Corporation’s firm transportation capacity is not a fixed quantity, due to the diverse web-like nature of its pipeline system, and is subject to change as the market identifies different transportation paths and receipt/ delivery point combinations. Supply Corporation currently has firm transportation service agreements for approximately 2,134 MDth per day (contracted transportation capacity). The Utility segment accounts for approximately 1,065 MDth per day or 49.9% of contracted transportation capacity, and the Energy Marketing and Exploration and Production segments represent another 126 MDth per day or 5.9% of contracted transportation capacity. The remaining 943 MDth or 44.2% of contracted transportation capacity is subject to firm contracts with nonaffiliated customers. At the beginning of 2011, 53.8% of Supply Corporation’s contracted transportation capacity was com- mitted under affiliate contracts that were scheduled to expire in 2011 or, subject to 2010 shipper or Supply Corporation notifications, could have been terminated effective in 2011. Based on contract expirations and termination notices received in 2010 for 2011 termination, and taking into account any known contract additions, contracted transportation capacity with affiliates is expected to increase 2.5% in 2011. Similarly, 35.9% of contracted transportation capacity was committed under unaffiliated shipper contracts that were scheduled to expire in 2011 or, subject to 2010 shipper or Supply Corporation notifications, could have been terminated effective in 2011. Based on contract expirations and termination notices received in 2010 for 2011 termination, and taking into account any known contract additions, contracted transportation capacity with unaffiliated shippers is expected to decrease 6.6% in 2011. This expected decrease is due largely to the relative increase in the price of natural gas supplies available at the receipt point on the United States/Canadian border at Niagara compared to the price of supplies at the delivery point of Leidy. Supply Corporation previously has been successful in marketing and obtaining executed contracts for available transportation capacity (at discounted rates when necessary), though costlier Niagara pricing will make these efforts more challenging in 2011. Supply Corporation expects to add significant incremental contracted transportation capacity in 2012 in connection with the development of the Marcellus Shale by independent producers. 5 At the beginning of 2011, Empire had service agreements in place for firm transportation capacity totaling up to approximately 686 MDth per day (including capacity on the Empire Connector). The majority of Empire’s transportation services are performed under contracts that allow Empire or the shipper to terminate the contract upon six or twelve months’ notice effective at the end of the contract term. The contracts also typically include “evergreen” language designed to allow the contracts to extend year-to-year at the end of the primary term. At the beginning of 2011, most of Empire’s firm contracted capacity (91.6%) was contracted as long-term full-year deals. One of those contracts expires during 2011, representing approximately 2.5% of Empire’s firm contracted capacity. In addition, Empire has some seasonal (winter-only) contracts that extend for multiple years, representing 2.4% of Empire’s firm contracted capacity. None of those multi-year, seasonal contracts expires during 2011. Arrangements for the remaining 6.0% of Empire’s firm contracted capacity are single-season or single-year contracts that expire during 2011 or potentially expire early in 2012, depending on whether Empire issues or receives termination notices during 2011. Two single-season or single-year contracts expire during 2011, representing 1.1% of Empire’s firm contracted capacity. At the beginning of 2011, the Utility segment accounted for 6.1% of Empire’s firm contracted capacity, and the Energy Marketing segment accounted for 2.0% of Empire’s firm contracted capacity, with the remaining 91.9% of Empire’s firm contracted capacity subject to contracts with nonaffiliated customers. Additional discussion of the Pipeline and Storage segment appears below under the headings “Sources and Availability of Raw Materials,” “Competition: The Pipeline and Storage Segment” and “Seasonality,” in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data. The Exploration and Production Segment The Exploration and Production segment contributed approximately 51.4% of the Company’s 2010 income from continuing operations and 49.8% of the Company’s 2010 net income available for common stock. Additional discussion of the Exploration and Production segment appears below under the headings “Sources and Availability of Raw Materials” and “Competition: The Exploration and Production Segment,” in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data. The Energy Marketing Segment The Energy Marketing segment contributed approximately 4.0% of the Company’s 2010 income from continuing operations and 3.9% of the Company’s 2010 net income available for common stock. Additional discussion of the Energy Marketing segment appears below under the headings “Sources and Availability of Raw Materials,” “Competition: The Energy Marketing Segment” and “Seasonality,” in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data. All Other Category and Corporate Operations The All Other category and Corporate operations incurred a net loss from continuing operations in 2010. The impact of this net loss from continuing operations in relation to the Company’s 2010 income from continuing operations was negative 0.6%. The All Other and Corporate category, including both continuing and discontinued operations, contributed approximately 2.4% of the Company’s 2010 net income available for common stock. Additional discussion of the All Other category and Corporate operations appears below in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data. Discontinued Operations In September 2010, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana. The Company’s landfill gas operations were maintained under the Company’s wholly owned subsidiary, Horizon LFG, which owned and operated these short distance landfill gas pipeline companies. These operations are presented in the Company’s financial statements as discontinued operations. 6 Additional discussion of the Company’s discontinued operations appears in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data. Sources and Availability of Raw Materials Natural gas is the principal raw material for the Utility segment. In 2010, the Utility segment purchased 67.1 Bcf of gas for delivery to its customers. Gas purchased from producers and suppliers in the southwestern United States and Canada under firm contracts (seasonal and longer) accounted for 53% of these purchases. Purchases of gas under contracts for one month or less accounted for 47% of the Utility segment’s 2010 purchases. Purchases from Chevron Natural Gas (16%), Total Gas & Power North America Inc. (12%) and Tenaska Marketing Ventures (10%) accounted for 38% of the Utility’s 2010 gas purchases. No other producer or supplier provided the Utility segment with more than 10% of its gas requirements in 2010. Supply Corporation transports and stores gas owned by its customers, whose gas originates in the southwestern, mid-continent and Appalachian regions of the United States as well as in Canada. Empire transports gas owned by its customers, whose gas originates in the southwestern and mid-continent regions of the United States as well as in Canada. Additional discussion of proposed pipeline projects appears below under “Competition: The Pipeline and Storage Segment” and in Item 7, MD&A. The Exploration and Production segment seeks to discover and produce raw materials (natural gas, oil and hydrocarbon liquids) as further described in this report in Item 7, MD&A and Item 8 at Note K — Business Segment Information and Note Q — Supplementary Information for Oil and Gas Producing Activities. The Energy Marketing segment depends on an adequate supply of natural gas to deliver to its customers. In 2010, this segment purchased 59.6 Bcf of gas, including 58.3 Bcf for delivery to its customers. The remaining 1.3 Bcf largely represents gas used in operations. The gas purchased by the Energy Marketing segment originates in either the Appalachian or mid-continent regions of the United States or in Canada. Competition Competition in the natural gas industry exists among providers of natural gas, as well as between natural gas and other sources of energy. The natural gas industry has gone through various stages of regulation. Apart from environmental and state utility commission regulation, the natural gas industry has experienced con- siderable deregulation. This has enhanced the competitive position of natural gas relative to other energy sources, such as fuel oil or electricity, since some of the historical regulatory impediments to adding customers and responding to market forces have been removed. In addition, management believes that the environmental advantages of natural gas have enhanced its competitive position relative to other fuels. The electric industry has been moving toward a more competitive environment as a result of changes in federal law in 1992 and initiatives undertaken by the FERC and various states. It remains unclear what the impact of any further restructuring in response to legislation or other events may be. The Company competes on the basis of price, service and reliability, product performance and other factors. Sources and providers of energy, other than those described under this “Competition” heading, do not compete with the Company to any significant extent. Competition: The Utility Segment The changes precipitated by the FERC’s restructuring of the natural gas industry in Order No. 636, which was issued in 1992, continue to reshape the roles of the gas utility industry and the state regulatory commis- sions. With respect to gas commodity service, in both New York and Pennsylvania, Distribution Corporation has retained a substantial majority of small sales customers. Almost all large-volume load, however, is served by unregulated retail marketers. In New York, approximately 20%, and in Pennsylvania, approximately 5%, of Distribution Corporation’s small-volume residential and commercial customers purchase their supplies from unregulated marketers. Retail competition for gas commodity service does not pose an acute competitive threat for Distribution Corporation because in both jurisdictions, utility cost of service is recovered through delivery rates and charges, not through charges for gas commodity service. Over the longer run, however, rate design 7 changes resulting from further customer migration to marketer service (e.g., “unbundling”) can expose utility companies such as Distribution Corporation to stranded costs and revenue erosion in the absence of com- pensating rate relief. Competition for transportation service to large-volume customers continues with local producers or pipeline companies attempting to sell or transport gas directly to end-users located within the Utility segment’s service territories without use of the utility’s facilities (i.e., bypass). In addition, competition continues with fuel oil suppliers. The Utility segment competes in its most vulnerable markets (the large commercial and industrial markets) by offering unbundled, flexible, high quality services. The Utility segment continues to develop or promote new sources and uses of natural gas or new services, rates and contracts. Competition: The Pipeline and Storage Segment Supply Corporation competes for market growth in the natural gas market with other pipeline companies transporting gas in the northeast United States and with other companies providing gas storage services. Supply Corporation has some unique characteristics which enhance its competitive position. Its facilities are located adjacent to Canada and the northeastern United States and provide part of the traditional link between gas- consuming regions of the eastern United States and gas-producing regions of Canada and the southwestern, southern and other continental regions of the United States. While costlier natural gas pricing at Niagara has decreased the importation and transportation of gas from that receipt point, new productive areas in the Appalachian region related to the development of the Marcellus Shale formation offer the opportunity for increased transportation services. Supply Corporation is pursuing its Northern Access pipeline expansion project to receive natural gas produced from the Marcellus Shale and transport it to key markets of Canada and the northeastern United States. For further discussion of this project, refer to Item 7, MD&A under the headings “Investing Cash Flow” and “Rate and Regulatory Matters.” Empire competes for market growth in the natural gas market with other pipeline companies transporting gas in the northeast United States and upstate New York in particular. Empire is well situated to provide transportation of gas received at the Niagara River at Chippawa and, with further expansion, Appalachian- sourced gas. Empire’s location provides it the opportunity to compete for an increased share of the gas transportation markets. As noted above, Empire has constructed the Empire Connector project, which expands its natural gas pipeline and enables Empire to serve new markets in New York and elsewhere in the Northeast. Empire is also pursuing its Tioga County Extension project, which will stretch approximately 16 miles south from its existing interconnection with Millennium Pipeline at Corning, New York, into Tioga County, Penn- sylvania. Like Supply Corporation’s Northern Access project, Empire’s Tioga County Extension project is designed to facilitate transportation of Marcellus Shale gas to key markets of Canada and the northeastern United States. For further discussion of this project, refer to Item 7, MD&A under the headings “Investing Cash Flow” and “Rate and Regulatory Matters.” Competition: The Exploration and Production Segment The Exploration and Production segment competes with other oil and natural gas producers and marketers with respect to sales of oil and natural gas. The Exploration and Production segment also competes, by competitive bidding and otherwise, with other oil and natural gas producers with respect to exploration and development prospects and mineral leaseholds. To compete in this environment, Seneca originates and acts as operator on certain of its prospects, seeks to minimize the risk of exploratory efforts through partnership-type arrangements, utilizes technology for both exploratory studies and drilling operations, and seeks market niches based on size, operating expertise and financial criteria. 8 Competition: The Energy Marketing Segment The Energy Marketing segment competes with other marketers of natural gas and with other providers of energy supply. Competition in this area is well developed with regard to price and services from local, regional and national marketers. Seasonality Variations in weather conditions can materially affect the volume of natural gas delivered by the Utility segment, as virtually all of its residential and commercial customers use natural gas for space heating. The effect that this has on Utility segment margins in New York is mitigated by a WNC, which covers the eight-month period from October through May. Weather that is warmer than normal results in an upward adjustment to customers’ current bills, while weather that is colder than normal results in a downward adjustment, so that in either case projected operating costs calculated at normal temperatures will be recovered. Volumes transported and stored by Supply Corporation and volumes transported by Empire may vary materially depending on weather, without materially affecting revenues. Supply Corporation’s and Empire’s allowed rates are based on a straight fixed-variable rate design which allows recovery of fixed costs in fixed monthly reservation charges. Variable charges based on volumes are designed to recover only the variable costs associated with actual transportation or storage of gas. Variations in weather conditions materially affect the volume of gas consumed by customers of the Energy Marketing segment. Volume variations have a corresponding impact on revenues within this segment. Capital Expenditures A discussion of capital expenditures by business segment is included in Item 7, MD&A under the heading “Investing Cash Flow.” Environmental Matters A discussion of material environmental matters involving the Company is included in Item 7, MD&A under the heading “Environmental Matters” and in Item 8, Note I — Commitments and Contingencies. Miscellaneous The Company and its wholly owned or majority-owned subsidiaries had a total of 1,859 full-time employees at September 30, 2010. This compares to 1,949 employees in the Company’s operations at September 30, 2009. The Company has agreements in place with collective bargaining units in New York and Pennsylvania. The agreements in New York are scheduled to expire in February 2013 and the agreements in Pennsylvania are scheduled to expire in April 2014 and May 2014. The Utility segment has numerous municipal franchises under which it uses public roads and certain other rights-of-way and public property for the location of facilities. When necessary, the Utility segment renews such franchises. The Company makes its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports, available free of charge on the Company’s internet website, www.nationalfuelgas.com, as soon as reasonably practicable after they are electronically filed with or furnished to the SEC. The information available at the Company’s internet website is not part of this Form 10-K or any other report filed with or furnished to the SEC. 9 Executive Officers of the Company as of November 15, 2010(1) Current Company Positions and Other Material Business Experience During Past Five Years Chairman of the Board of Directors of the Company since March 2010 and Chief Executive Officer of the Company since February 2008.

The Company is a holding company with no significant assets other than the stock of its operating subsidiaries. In order to meet its financial needs, the Company relies exclusively on repayments of principal and interest on intercompany loans made by the Company to its operating subsidiaries and income from dividends and other cash flow from the subsidiaries. Such operating subsidiaries may not generate sufficient net income to pay upstream dividends or generate sufficient cash flow to make payments of principal or interest on such intercompany loans. The Company is dependent on credit markets to successfully execute its business strategies. The Company relies upon short-term bank borrowings, commercial paper markets and longer-term capital markets to finance capital requirements not satisfied by cash flow from operations. The Company is dependent on these capital sources to provide capital to its subsidiaries to fund operations, acquire, maintain and develop properties, and execute growth strategies. The availability and cost of credit sources may be cyclical and these capital sources may not remain available to the Company. Turmoil in credit markets may make it difficult for the Company to obtain financing on acceptable terms or at all for working capital, capital expenditures and other investments, or to refinance maturing debt on favorable terms. These difficulties could adversely affect the Company’s growth strategies, operations and financial performance. The Company’s ability to borrow under its credit facilities and commercial paper agreements, and its ability to issue long-term debt under its indentures, depend on the Company’s compliance with its obligations under the facilities, agreements and indentures. In addition, the Company’s short-term bank loans are in the form of floating rate debt or debt that may have rates fixed for very short periods of time, resulting in exposure to interest rate fluctuations in the absence of interest rate hedging transactions. The cost of long-term debt, the interest rates on the Company’s short-term bank loans and the ability of the Company to issue commercial paper are affected by its debt credit ratings published by Standard & Poor’s Ratings Service (“S&P”), Moody’s Investors Service and Fitch Ratings Service. A downgrade in the Company’s credit ratings could increase borrowing costs and negatively impact the availability of capital from banks, commercial paper purchasers and other sources. The Company may be adversely affected by economic conditions and their impact on our suppliers and customers. Periods of slowed economic activity generally result in decreased energy consumption, particularly by industrial and large commercial companies. As a consequence, national or regional recessions or other downturns in economic activity could adversely affect the Company’s revenues and cash flows or restrict its future growth. Economic conditions in the Company’s utility service territories and energy marketing territories also impact its collections of accounts receivable. All of the Company’s segments are exposed to risks associated with the creditworthiness or performance of key suppliers and customers, many of which may be adversely affected by volatile conditions in the financial markets. These conditions could result in financial instability or other adverse effects at any of our suppliers or customers. For example, counterparties to the Company’s commodity hedging arrangements or commodity sales contracts might not be able to perform their obligations under these arrangements or contracts. Customers of the Company’s Utility and Energy Marketing segments may have particular trouble paying their bills during periods of declining economic activity and high com- modity prices, potentially resulting in increased bad debt expense and reduced earnings. Any of these events could have a material adverse effect on the Company’s results of operations, financial condition and cash flows. The Company’s credit ratings may not reflect all the risks of an investment in its securities. The Company’s credit ratings are an independent assessment of its ability to pay its obligations. Conse- quently, real or anticipated changes in the Company’s credit ratings will generally affect the market value of the specific debt instruments that are rated, as well as the market value of the Company’s common stock. The 11 Company’s credit ratings, however, may not reflect the potential impact on the value of its common stock of risks related to structural, market or other factors discussed in this Form 10-K. The Company’s need to comply with comprehensive, complex, and sometimes unpredictable government regulations may increase its costs and limit its revenue growth, which may result in reduced earnings. While the Company generally refers to its Utility segment and its Pipeline and Storage segment as its “regulated segments,” there are many governmental regulations that have an impact on almost every aspect of the Company’s businesses. Existing statutes and regulations may be revised or reinterpreted and new laws and regulations may be adopted or become applicable to the Company, which may increase the Company’s costs or affect its business in ways that the Company cannot predict. In the Company’s Utility segment, the operations of Distribution Corporation are subject to the jurisdiction of the NYPSC, the PaPUC and, with respect to certain transactions, the FERC. The NYPSC and the PaPUC, among other things, approve the rates that Distribution Corporation may charge to its utility customers. Those approved rates also impact the returns that Distribution Corporation may earn on the assets that are dedicated to those operations. If Distribution Corporation is required in a rate proceeding to reduce the rates it charges its utility customers, or to the extent Distribution Corporation is unable to obtain approval for rate increases from these regulators, particularly when necessary to cover increased costs (including costs that may be incurred in connection with governmental investigations or proceedings or mandated infrastructure inspection, mainte- nance or replacement programs), earnings may decrease. In addition to their historical methods of utility regulation, both the PaPUC and NYPSC have established competitive markets in which customers may purchase gas commodity from unregulated marketers, in addition to utility companies. Retail competition for gas commodity service does not pose an acute competitive threat for Distribution Corporation, because in both jurisdictions, it recovers its cost of service through delivery rates and charges, and not through any mark-up on the gas commodity purchased by its customers. Over the longer run, however, rate design changes resulting from further customer migration to marketer service (“unbundling”) can expose utilities such as Distribution Corporation to stranded costs and revenue erosion in the absence of compensating rate relief. Both the NYPSC and the PaPUC have instituted proceedings for the purpose of promoting conservation of energy commodities, including natural gas. In New York, Distribution Corporation implemented a Conser- vation Incentive Program that promotes conservation and efficient use of natural gas by offering customer rebates for high-efficiency appliances, among other things. The intent of conservation and efficiency programs is to reduce customer usage of natural gas. Under traditional volumetric rates, reduced usage by customers results in decreased revenues to the Utility. To prevent revenue erosion caused by conservation, the NYPSC approved a “revenue decoupling mechanism” that renders Distribution Corporation’s New York division financially indifferent to the effects of conservation. In Pennsylvania, although a generic statewide proceeding is pending, the PaPUC has not yet directed Distribution Corporation to implement conservation measures. If the NYPSC were to revoke the revenue decoupling mechanism in a future proceeding or the PaPUC were to adopt a conservation program without a revenue decoupling mechanism or other changes in rate design, reduced customer usage could decrease revenues, forcing Distribution Corporation to file for rate relief. In New York, aggressive generic statewide programs created under the label of efficiency or conservation continue to generate a sizable utility funding requirement for state agencies that administer those programs. Although utilities are authorized to recover the cost of efficiency and conservation program funding through special rates and surcharges, the resulting upward pressure on customer rates, coupled with increased assessments and taxes, could affect future tolerance for traditional utility rate increases, especially if natural gas commodity costs were to increase. The Company is subject to the jurisdiction of the FERC with respect to Supply Corporation, Empire and some transactions performed by other Company subsidiaries, including Seneca Resources, Distribution Cor- poration and NFR. The FERC, among other things, approves the rates that Supply Corporation and Empire may charge to their natural gas transportation and/or storage customers. Those approved rates also impact the returns that Supply Corporation and Empire may earn on the assets that are dedicated to those operations. State 12 commissions can also petition the FERC to investigate whether Supply Corporation’s and Empire’s rates are still just and reasonable, and if not, to reduce those rates prospectively. If Supply Corporation or Empire is required in a rate proceeding to reduce the rates it charges its natural gas transportation and/or storage customers, or if Supply Corporation or Empire is unable to obtain approval for rate increases, particularly when necessary to cover increased costs, Supply Corporation’s or Empire’s earnings may decrease. The FERC also possesses significant penalty authority with respect to violations of the laws and regulations it administers. Supply Corporation, Empire and, to the extent subject to FERC jurisdiction, the Company’s other subsidiaries are subject to the FERC’s penalty authority. In the wake of certain pipeline accidents not involving the Company, new laws or regulations may be adopted regarding pipeline safety. Proposals have been made at the federal level with respect to matters such as reporting of pipeline accidents, increased fines for pipeline safety violations, the designation of additional high consequence areas along pipelines, minimum requirements for leak detection systems, installation of emergency flow restricting devices, and revision of valve spacing requirements. In addition, unrelated to these safety initiatives, the EPA in April 2010 issued an Advance Notice of Proposed Rulemaking reassessing its regulations governing the use and distribution in commerce of PCBs. The EPA is considering, among other things, a proposal to eliminate by 2020 the PCB use authorization for natural gas pipeline systems, and a proposal to eliminate the authorization for storage of PCB-containing equipment for reuse. The EPA projects that it may issue a Notice of Proposed Rulemaking in March 2012. If as a result of new laws or regulations the Company incurs material costs that it is unable to recover fully through rates or otherwise offset, the Company’s financial condition, results of operations, and cash flows would be adversely affected. The Company’s liquidity, and in certain circumstances, its earnings, could be adversely affected by the cost of purchasing natural gas during periods in which natural gas prices are rising significantly. Tariff rate schedules in each of the Utility segment’s service territories contain purchased gas adjustment clauses which permit Distribution Corporation to file with state regulators for rate adjustments to recover increases in the cost of purchased gas. Assuming those rate adjustments are granted, increases in the cost of purchased gas have no direct impact on profit margins. Nevertheless, increases in the cost of purchased gas affect cash flows and can therefore impact the amount or availability of the Company’s capital resources. The Company has issued commercial paper and used short-term borrowings in the past to temporarily finance storage inventories and purchased gas costs, and although the Company expects to do so in the future, it may not be able to access the markets for such borrowings at attractive interest rates or at all. Distribution Corporation is required to file an accounting reconciliation with the regulators in each of the Utility segment’s service territories regarding the costs of purchased gas. Due to the nature of the regulatory process, there is a risk of a disallowance of full recovery of these costs during any period in which there has been a substantial upward spike in these costs. Any material disallowance of purchased gas costs could have a material adverse effect on cash flow and earnings. In addition, even when Distribution Corporation is allowed full recovery of these purchased gas costs, during periods when natural gas prices are significantly higher than historical levels, customers may have trouble paying the resulting higher bills, and Distribution Corporation’s bad debt expenses may increase and ultimately reduce earnings. Changes in interest rates may affect the Company’s ability to finance capital expenditures and to refinance maturing debt. The Company’s ability to finance capital expenditures and to refinance maturing debt will depend in part upon interest rates. The direction in which interest rates may move is uncertain. Declining interest rates have generally been believed to be favorable to utilities, while rising interest rates are generally believed to be unfavorable, because of the levels of debt that utilities may have outstanding. In addition, the Company’s authorized rate of return in its regulated businesses is based upon certain assumptions regarding interest rates. If interest rates are lower than assumed rates, the Company’s authorized rate of return could be reduced. If interest rates are higher than assumed rates, the Company’s ability to earn its authorized rate of return may be adversely impacted. 13 Fluctuations in oil and natural gas prices could adversely affect revenues, cash flows and profitability. Operations in the Company’s Exploration and Production segment are materially dependent on prices received for its oil and natural gas production. Both short-term and long-term price trends affect the economics of exploring for, developing, producing, gathering and processing oil and natural gas. Oil and natural gas prices can be volatile and can be affected by: weather conditions, including natural disasters; the supply and price of foreign oil and natural gas; the level of consumer product demand; national and worldwide economic conditions, including economic disruptions caused by terrorist activities, acts of war or major accidents; political conditions in foreign countries; the price and availability of alternative fuels; the proximity to, and availability of capacity on transportation facilities; regional levels of supply and demand; energy conservation measures; and government regulations, such as regulation of greenhouse gas emissions and natural gas transportation, royalties, and price controls. The Company sells most of the oil and natural gas that it produces at current market prices rather than through fixed-price contracts, although as discussed below, the Company frequently hedges the price of a significant portion of its future production in the financial markets. The prices the Company receives depend upon factors beyond the Company’s control, including the factors affecting price mentioned above. The Company believes that any prolonged reduction in oil and natural gas prices could restrict its ability to continue the level of exploration and production activity the Company otherwise would pursue, which could have a material adverse effect on its revenues, cash flows and results of operations. In the Company’s Pipeline and Storage segment, significant changes in the price differential between equivalent quantities of natural gas at different geographic locations or between futures contracts for natural gas having different delivery dates could adversely impact the Company. For example, if the price of natural gas at a particular receipt point on the Company’s pipeline system increases relative to the price of natural gas at other locations, then the volume of natural gas received by the Company at the relatively more expensive receipt point may decrease, or the price the Company charges to transport that natural gas may decrease. Additionally, if the prices of natural gas futures contracts for winter deliveries to locations served by the Pipeline and Storage segment decline relative to the prices of such contracts for summer deliveries (for example, as a result of increased production of natural gas within the Pipeline and Storage segment’s geographic area), then demand for the Company’s natural gas storage services driven by that price differential could decrease. These changes could adversely affect revenues, cash flows and results of operations. The Company has significant transactions involving price hedging of its oil and natural gas production as well as its fixed price purchase and sale commitments. In order to protect itself to some extent against unusual price volatility and to lock in fixed pricing on oil and natural gas production for certain periods of time, the Company’s Exploration and Production segment regularly enters into commodity price derivatives contracts (hedging arrangements) with respect to a portion of its expected production. These contracts may at any time cover as much as approximately 80% of the Company’s expected energy production during the upcoming 12-month period. These contracts reduce exposure to subsequent price drops but can also limit the Company’s ability to benefit from increases in commodity prices. In addition, the Energy Marketing segment enters into certain hedging arrangements, primarily with respect to its fixed price purchase and sales commitments and its gas stored underground. The Company’s Pipeline and Storage segment enters into hedging arrangements with respect to certain sales of efficiency gas. Under applicable accounting rules currently in effect, the Company’s hedging arrangements are subject to quarterly effectiveness tests. Inherent within those effectiveness tests are assumptions concerning the long-term price differential between different types of crude oil, assumptions concerning the difference between published natural gas price indexes established by pipelines in which hedged natural gas production is delivered and the reference price established in the hedging arrangements, assumptions regarding the levels of production that will be achieved and, with regard to fixed price commitments, assumptions regarding the creditworthiness of certain customers and their forecasted consumption of natural gas. Depending on market conditions for natural gas and crude oil and the levels of production actually achieved, it is possible that certain of those assumptions may change in the future, and, depending on the magnitude of any such changes, it is possible that a portion of the Company’s hedges may no longer be considered highly effective. In that case, gains or losses from the ineffective derivative financial instruments would be marked-to-market on the income statement without 14 regard to an underlying physical transaction. Gains would occur to the extent that natural gas and crude oil hedge prices exceed market prices for the Company’s natural gas and crude oil production, and losses would occur to the extent that market prices for the Company’s natural gas and crude oil production exceed hedge prices. Use of energy commodity price hedges also exposes the Company to the risk of non-performance by a contract counterparty. These parties might not be able to perform their obligations under the hedge arrangements. It is the Company’s policy that the use of commodity derivatives contracts comply with various restrictions in effect in respective business segments. For example, in the Exploration and Production segment, commodity derivatives contracts must be confined to the price hedging of existing and forecast production, and in the Energy Marketing segment, commodity derivatives with respect to fixed price purchase and sales commitments must be matched against commitments reasonably certain to be fulfilled. Similar restrictions apply in the Pipeline and Storage segment. The Company maintains a system of internal controls to monitor compliance with its policy. However, unauthorized speculative trades, if they were to occur, could expose the Company to substantial losses to cover positions in its derivatives contracts. In addition, in the event the Company’s actual production of oil and natural gas falls short of hedged forecast production, the Company may incur substantial losses to cover its hedges. You should not place undue reliance on reserve information because such information represents estimates. This Form 10-K contains estimates of the Company’s proved oil and natural gas reserves and the future net cash flows from those reserves that were prepared by the Company’s petroleum engineers and audited by independent petroleum engineers. Petroleum engineers consider many factors and make assumptions in estimating oil and natural gas reserves and future net cash flows. These factors include: historical production from the area compared with production from other producing areas; the assumed effect of governmental regulation; and assumptions concerning oil and natural gas prices, production and development costs, severance and excise taxes, and capital expenditures. Lower oil and natural gas prices generally cause estimates of proved reserves to be lower. Estimates of reserves and expected future cash flows prepared by different engineers, or by the same engineers at different times, may differ substantially. Ultimately, actual production, revenues and expenditures relating to the Company’s reserves will vary from any estimates, and these variations may be material. Accordingly, the accuracy of the Company’s reserve estimates is a function of the quality of available data and of engineering and geological interpretation and judgment. If conditions remain constant, then the Company is reasonably certain that its reserve estimates represent economically recoverable oil and natural gas reserves and future net cash flows. If conditions change in the future, then subsequent reserve estimates may be revised accordingly. You should not assume that the present value of future net cash flows from the Company’s proved reserves is the current market value of the Company’s estimated oil and natural gas reserves. In accordance with SEC requirements that became effective for the Company with its Form 10-K for the period ended September 30, 2010, the Company bases the estimated discounted future net cash flows from its proved reserves on 12-month average prices for oil and natural gas (based on first day of the month prices and adjusted for hedging) and on costs as of the date of the estimate (under prior SEC requirements, the Company utilized market prices as of the last day of the period). Actual future prices and costs may differ materially from those used in the net present value estimate. Any significant price changes will have a material effect on the present value of the Company’s reserves. Petroleum engineering is a subjective process of estimating underground accumulations of natural gas and other hydrocarbons that cannot be measured in an exact manner. The process of estimating oil and natural gas reserves is complex. The process involves significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. Future economic and operating conditions are uncertain, and changes in those conditions could cause a revision to the Company’s reserve estimates in the future. Estimates of economically recoverable oil and natural gas reserves and of future net cash flows depend upon a number of variable factors and assumptions, including historical production from the area 15 compared with production from other comparable producing areas, and the assumed effects of regulations by governmental agencies. Because all reserve estimates are to some degree subjective, each of the following items may differ materially from those assumed in estimating reserves: the quantities of oil and natural gas that are ultimately recovered, the timing of the recovery of oil and natural gas reserves, the production and operating costs incurred, the amount and timing of future development and abandonment expenditures, and the price received for the production. The amount and timing of actual future oil and natural gas production and the cost of drilling are difficult to predict and may vary significantly from reserves and production estimates, which may reduce the Company’s earnings. There are many risks in developing oil and natural gas, including numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves and in projecting future rates of production and timing of development expenditures. The future success of the Company’s Exploration and Production segment depends on its ability to develop additional oil and natural gas reserves that are economically recoverable, and its failure to do so may reduce the Company’s earnings. The total and timing of actual future production may vary significantly from reserves and production estimates. The Company’s drilling of development wells can involve significant risks, including those related to timing, success rates, and cost overruns, and these risks can be affected by lease and rig availability, geology, and other factors. Drilling for oil and natural gas can be unprofitable, not only from non-productive wells, but from productive wells that do not produce sufficient revenues to return a profit. Also, title problems, weather conditions, governmental requirements, including completion of environmental impact analyses and compliance with other environmental laws and regulations, and shortages or delays in the delivery of equipment and services can delay drilling operations or result in their cancellation. The cost of drilling, completing, and operating wells is often uncertain, and new wells may not be productive or the Company may not recover all or any portion of its investment. Production can also be delayed or made uneconomic if there is insufficient gathering, processing and transportation capacity available at an economic price to get that production to a location where it can be profitably sold. Without continued successful exploitation or acquisition activities, the Company’s reserves and revenues will decline as a result of its current reserves being depleted by production. The Company cannot make assurances that it will be able to find or acquire additional reserves at acceptable costs. Financial accounting requirements regarding exploration and production activities may affect the Company’s profitability. The Company accounts for its exploration and production activities under the full cost method of accounting. Each quarter, the Company must compare the level of its unamortized investment in oil and natural gas properties to the present value of the future net revenue projected to be recovered from those properties according to methods prescribed by the SEC. In determining present value, the Company uses 12-month average prices for oil and natural gas (based on first day of the month prices and adjusted for hedging). If, at the end of any quarter, the amount of the unamortized investment exceeds the net present value of the projected future cash flows, such investment may be considered to be “impaired,” and the full cost accounting rules require that the investment must be written down to the calculated net present value. Such an instance would require the Company to recognize an immediate expense in that quarter, and its earnings would be reduced. Depending on the magnitude of any decrease in average prices, that charge could be material. Environmental regulation significantly affects the Company’s business. The Company’s business operations are subject to federal, state, and local laws and regulations relating to environmental protection. These laws and regulations concern the generation, storage, transportation, disposal or discharge of contaminants and greenhouse gases into the environment, the reporting of such matters, and the general protection of public health, natural resources, wildlife and the environment. Costs of compliance and liabilities could negatively affect the Company’s results of operations, financial condition and cash flows. In addition, compliance with environmental laws and regulations could require unexpected capital expenditures at the Company’s facilities or delay or cause the cancellation of expansion projects or oil and natural gas drilling 16 activities. Because the costs of complying with environmental regulations are significant, additional regulation could negatively affect the Company’s business. Although the Company cannot predict the impact of the interpretation or enforcement of EPA standards or other federal, state and local laws or regulations, the Company’s costs could increase if environmental laws and regulations change. Legislative and regulatory measures to address climate change and greenhouse gas emissions are in various phases of discussion or implementation. The EPA has determined that stationary sources of significant greenhouse gas emissions will be required under the federal Clean Air Act to obtain permits covering such emissions beginning in January 2011. In addition, the U.S. Congress has been considering bills that would establish a cap-and-trade program to reduce emissions of greenhouse gases. Legislation or regulation that restricts greenhouse gas emissions could increase the Company’s cost of environmental compliance by requiring the Company to install new equipment to reduce emissions from larger facilities and/or purchase emission allowances. International, federal, state or regional climate change and greenhouse gas initiatives could also delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals with regard to existing and new facilities, or impose additional monitoring and reporting requirements. Climate change and greenhouse gas initiatives, and incentives to conserve energy or use alternative energy sources, could also reduce demand for oil and natural gas. The effect (material or not) on the Company of any new legislative or regulatory measures will depend on the particular provisions that are ultimately adopted. Increased regulation of exploration and production activities, including hydraulic fracturing, could adversely impact the Company. Due to the burgeoning Marcellus Shale natural gas play in the northeast United States, together with the fiscal difficulties faced by state governments in New York and Pennsylvania, various state legislative and regulatory initiatives regarding the exploration and production business have been proposed. These initiatives include potential new or updated statutes and regulations governing the drilling, casing, cementing, testing and monitoring of wells, the protection of water supplies, hydraulic fracturing of wells, surface owners’ rights and damage compensation, the spacing of wells, and environmental and safety issues regarding natural gas pipelines. New severance taxes for oil and gas production are also possible. Additionally, legislative initiatives in the U.S. Congress and regulatory studies, proceedings or initiatives at federal or state agencies focused on the hydraulic fracturing process could result in additional permitting, compliance, reporting and disclosure requirements. If adopted, any such new state or federal legislation or regulation could lead to operational delays or restrictions, increased operating costs, additional regulatory burdens and increased risks of litigation for the Company’s Exploration and Production segment. The nature of the Company’s operations presents inherent risks of loss that could adversely affect its results of operations, financial condition and cash flows. The Company’s operations in its various reporting segments are subject to inherent hazards and risks such as: fires; natural disasters; explosions; geological formations with abnormal pressures; blowouts during well drilling; collapses of wellbore casing or other tubulars; pipeline ruptures; spills; and other hazards and risks that may cause personal injury, death, property damage, environmental damage or business interruption losses. Additionally, the Company’s facilities, machinery, and equipment may be subject to sabotage. Any of these events could cause a loss of hydrocarbons, environmental pollution, claims for personal injury, death, property damage or business interruption, or governmental investigations, recommendations, claims, fines or penalties. As protection against operational hazards, the Company maintains insurance coverage against some, but not all, potential losses. In addition, many of the agreements that the Company executes with contractors provide for the division of responsibilities between the contractor and the Company, and the Company seeks to obtain an indemnification from the contractor for certain of these risks. The Company is not always able, however, to secure written agreements with its contractors that contain indemnification, and sometimes the Company is required to indemnify others. Insurance or indemnification agreements when obtained may not adequately protect the Company against liability from all of the consequences of the hazards described above. The occurrence of an event not fully insured or indemnified against, the imposition of fines, penalties or mandated programs by governmental 17 authorities, the failure of a contractor to meet its indemnification obligations, or the failure of an insurance company to pay valid claims could result in substantial losses to the Company. In addition, insurance may not be available, or if available may not be adequate, to cover any or all of these risks. It is also possible that insurance premiums or other costs may rise significantly in the future, so as to make such insurance prohibitively expensive. Due to the significant cost of insurance coverage for named windstorms in the Gulf of Mexico, the Company determined that it was not economical to purchase insurance to fully cover its exposures related to such storms. It is possible that named windstorms in the Gulf of Mexico could have a material adverse effect on the Company’s results of operations, financial condition and cash flows. Hazards and risks faced by the Company, and insurance and indemnification obtained or provided by the Company, may subject the Company to litigation or administrative proceedings from time to time. Such litigation or proceedings could result in substantial monetary judgments, fines or penalties against the Company or be resolved on unfavorable terms, the result of which could have a material adverse effect on the Company’s results of operations, financial condition and cash flows. The increasing costs of certain employee and retiree benefits could adversely affect the Company’s results. The Company’s earnings and cash flow may be impacted by the amount of income or expense it expends or records for employee benefit plans. This is particularly true for pension and other post-retirement benefit plans, which are dependent on actual plan asset returns and factors used to determine the value and current costs of plan benefit obligations. In addition, if medical costs rise at a rate faster than the general inflation rate, the Company might not be able to mitigate the rising costs of medical benefits. Increases to the costs of pension, other post-retirement and medical benefits could have an adverse effect on the Company’s financial results. Significant shareholders or potential shareholders may attempt to effect changes at the Company or acquire control over the Company, which could adversely affect the Company’s results of operations and financial condition. In January 2008, the Company entered into an agreement with New Mountain Vantage GP, L.L.C. (“New Mountain”) and certain parties related to New Mountain, including the California Public Employees’ Retirement System (collectively, “Vantage”), to settle a proxy contest pertaining to the election of directors to the Company’s Board of Directors at the Company’s 2008 Annual Meeting of Stockholders. That settlement agreement expired on September 15, 2009. Vantage or other existing or potential shareholders may engage in proxy solicitations or advance shareholder proposals after the Company’s 2011 Annual Meeting of Stockholders, or otherwise attempt to effect changes or acquire control over the Company. Campaigns by shareholders to effect changes at publicly traded companies are sometimes led by investors seeking to increase short-term shareholder value through actions such as financial restructuring, increased debt, special dividends, stock repurchases or sales of assets or the entire company. Responding to proxy contests and other actions by activist shareholders can be costly and time-consuming, disrupting the Company’s operations and diverting the attention of the Company’s Board of Directors and senior management from the pursuit of business strategies. As a result, shareholder campaigns could adversely affect the Company’s results of operations and financial condition. Item 1B Unresolved Staff Comments None Item 2 Properties General Information on Facilities The net investment of the Company in property, plant and equipment was $3.5 billion at September 30, 2010. Approximately 59% of this investment was in the Utility and Pipeline and Storage segments, whose 18 operations are located primarily in western and central New York and northwestern Pennsylvania. The Exploration and Production segment, which has the next largest investment in net property, plant and equipment (39%), is primarily located in California, in the Appalachian region of the United States, and in the shallow waters of the Gulf Coast region of Texas and Louisiana. The remaining net investment in property, plant and equipment consisted of the All Other and Corporate operations (2%). During the past five years, the Company has made additions to property, plant and equipment in order to expand and improve transmission and distribution facilities for both retail and transportation customers. Net property, plant and equipment has increased $610.9 million, or 21.5%, since 2005. In September 2010, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana. The net property, plant and equipment of the landfill gas operations at the date of sale was $8.8 million. In addition, during 2007, the Company sold SECI, Seneca’s wholly owned subsidiary that operated in Canada. The net property, plant and equipment of SECI at the date of sale was $107.7 million. The Utility segment had a net investment in property, plant and equipment of $1.2 billion at September 30, 2010. The net investment in its gas distribution network (including 14,836 miles of distribution pipeline) and its service connections to customers represent approximately 51% and 34%, respectively, of the Utility segment’s net investment in property, plant and equipment at September 30, 2010. The Pipeline and Storage segment had a net investment of $858.2 million in property, plant and equipment at September 30, 2010. Transmission pipeline represents 41% of this segment’s total net investment and includes 2,356 miles of pipeline utilized to move large volumes of gas throughout its service area. Storage facilities represent 20% of this segment’s total net investment and consist of 31 storage fields, four of which are jointly owned and operated with certain pipeline suppliers, and 431 miles of pipeline. Net investment in storage facilities includes $86.3 million of gas stored underground-noncurrent, representing the cost of the gas utilized to maintain pressure levels for normal operating purposes as well as gas maintained for system balancing and other purposes, including that needed for no-notice transportation service. The Pipeline and Storage segment has 31 compressor stations with 98,194 installed compressor horsepower that represent 13% of this segment’s total net investment in property, plant and equipment. The Exploration and Production segment had a net investment in property, plant and equipment of $1.3 billion at September 30, 2010. The Utility and Pipeline and Storage segments’ facilities provided the capacity to meet the Company’s 2010 peak day sendout, including transportation service, of 1,608 MMcf, which occurred on January 11, 2010. Withdrawals from storage of 595.4 MMcf provided approximately 37.0% of the requirements on that day. Company maps are included in exhibit 99.2 of this Form 10-K and are incorporated herein by reference. Exploration and Production Activities The Company is engaged in the exploration for, and the development and purchase of, natural gas and oil reserves in California, in the Appalachian region of the United States, and in the shallow waters of the Gulf Coast region of Texas and Louisiana. The Company has been increasing its emphasis in the Appalachian region, primarily in the Marcellus Shale, and has been decreasing its emphasis in the Gulf Coast region. Also, Exploration and Production operations were conducted in the provinces of Alberta, Saskatchewan and British Columbia in Canada, until the sale of these properties on August 31, 2007. Further discussion of oil and gas producing activities is included in Item 8, Note Q — Supplementary Information for Oil and Gas Producing Activities. Note Q sets forth proved developed and undeveloped reserve information for Seneca. The September 30, 2010 reserves shown in Note Q have been impacted by the SEC’s final rule on Modernization of Oil and Gas Reporting. The most notable change of the final rule includes the replacement of the single day period-end pricing used to value oil and gas reserves with an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. The reserves were estimated by Seneca’s geologists and engineers and were audited by independent petroleum engineers from Netherland, Sewell & Associates, Inc. 19 The Company’s proved oil and gas reserve estimates are prepared by the Company’s reservoir engineers who meet the qualifications of Reserve Estimator per the “Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information” promulgated by the Society of Petroleum Engineers as of February 19, 2007. The Company maintains comprehensive internal reserve guidelines and a continuing education program designed to keep its staff up to date with current SEC regulations and guidance. The Company’s Vice President of Reservoir Engineering is the primary technical person responsible for overseeing the Company’s reserve estimation process and engaging and overseeing the third party reserve audit. His qualifications include a Bachelor of Science Degree in Petroleum Engineering and over 25 years of Petroleum Engineering experience with both major and independent oil and gas companies. He has maintained oversight of the Company’s reserve estimation process for the past seven years. He is a member of the Society of Petroleum Engineers and a Registered Professional Engineer in the State of Texas. The Company maintains a system of internal controls over the reserve estimation process. Management reviews the price, heat content, lease operating cost and future investment assumptions used in the economic model to determine the reserves. The Vice President of Reservoir Engineering reviews and approves all new reserve assignments and significant reserve revisions. Access to the Reserve database is restricted. Significant changes to the reserve report are reviewed by senior management on a quarterly basis. Periodically, the Company’s internal audit department assesses the design of these controls and performs testing to determine the effectiveness of such controls. All of the Company’s reserve estimates are audited annually by Netherland, Sewell and Associates, Inc. (NSAI). Since 1961, NSAI has evaluated gas and oil properties and independently certified petroleum reserve quantities in the United States and internationally under the Texas Board of Professional Engineers Registration No. F-002699. The primary technical persons (employed by NSAI) that are responsible for leading the audit include an engineer registered with the State of Texas (with 12 years of experience in petroleum engineering and six years of experience in the estimation and evaluation of reserves) and a Certified Petroleum Geologist and Geophysicist in the State of Texas (with 32 years of experience in petroleum geosciences and 21 years of experience in the estimation and evaluation of reserves). NSAI was satisfied with the methods and procedures used by the Company to prepare its reserve estimates at September 30, 2010 and did not identify any problems which would cause it to take exception to those estimates. The reliable technologies that were utilized in estimating the reserves include wire line open-hole log data, performance data, log cross sections, core data, and statistical analysis. The statistical method utilized production performance from both the Company’s and competitor’s wells. Geophysical data include data from the Company’s wells, published documents, and state data-sites and were used to confirm continuity of the formation. Extension and discovery reserves added as a result of reliable technologies were not material. Seneca’s proved developed and undeveloped natural gas reserves increased from 249 Bcf at September 30, 2009 to 428 Bcf at September 30, 2010. This increase is attributed primarily to extensions and discoveries (193.1 Bcf), primarily in the Appalachian region (190.0 Bcf), and revisions of previous estimates (16.7 Bcf). This increase was partially offset by production of 30.3 Bcf. Seneca’s proved developed and undeveloped oil reserves decreased from 46,587 Mbbl at September 30, 2009 to 45,239 Mbbl at September 30, 2010. This decrease is attributed to production (3,220 Mbbl), primarily occurring in the West Coast region (2,669 Mbbl). This decrease was partly offset by extensions and discoveries (1,054 Mbbl) and revisions of previous estimates (818 Mbbl). On a Bcfe basis, Seneca’s proved developed and undeveloped reserves increased from 528 Bcfe at September 30, 2009 to 700 Bcfe at September 30, 2010. Seneca’s proved developed and undeveloped natural gas reserves increased from 226 Bcf at September 30, 2008 to 249 Bcf at September 30, 2009. This increase is attributed primarily to extensions and discoveries (59.2 Bcf), primarily in the Appalachian region (49.2 Bcf). This increase was partially offset by production of 22.3 Bcf, negative revisions of previous estimates (9.6 Bcf) and sales of minerals in place (4.7 Bcf) in the Gulf Coast region. Seneca’s proved developed and undeveloped oil reserves increased from 46,198 Mbbl at September 30, 2008 to 46,587 Mbbl at September 30, 2009. This increase is attributed to purchases of minerals in place (2,115 Mbbl) in the West Coast region, extensions and discoveries (1,213 Mbbl), and revisions of previous estimates (449 Mbbl). These increases were largely offset by production (3,373 Mbbl), primarily occurring in the West Coast region (2,674 Mbbl). On a Bcfe basis, Seneca’s proved developed and undeveloped reserves increased from 503 Bcfe at September 30, 2008 to 528 Bcfe at September 30, 2009. 20 The Company’s proved undeveloped (PUD) reserves increased from 87 Bcfe at September 30, 2009 to 177 Bcfe at September 30, 2010. Undeveloped reserves in the Marcellus Shale increased from 11 Bcf at September 30, 2009 to 110 Bcf at September 30, 2010. There was a material increase in undeveloped reserves at September 30, 2010 as a result of its Marcellus Shale reserve additions. The increase in undeveloped reserves in the Marcellus Shale is partially attributable to the change in SEC regulations allowing the recognition of PUD reserves more than one direct offset location away from existing production with reasonable certainty using reliable technology. The Company’s total PUD reserves are 25% of total proved reserves at September 30, 2010, up from 16% of total proved reserves at September 30, 2009. The increase in PUD reserves in 2010 of 90 Bcfe is a result of 111 Bcfe in new PUD reserve additions (105 Bcfe from the Marcellus Shale), offset by 17 Bcfe in PUD conversions to developed reserves and 4 Bcfe in downward PUD revisions. The downward revisions were primarily from the removal of 51 PUD locations in the Upper Devonian play. This was the result of Seneca’s decision in 2010 to significantly reduce its 5-year investment plan for the Upper Devonian as a result of lower forward gas price expectations. The Company invested $28.9 million during the year ended September 30, 2010 to convert 17 Bcfe of PUD reserves to developed reserves. This represents 19% of the PUD reserves booked at September 30, 2009. In 2011, the Company estimates that it will invest approximately $140 million to develop the PUD reserves. The Company is committed to developing its PUD reserves within five years of being recorded as PUD reserves as required by the SEC’s final rule on Modernization of Oil and Gas Reporting. At September 30, 2010, the Company does not have a material concentration of proved undeveloped reserves that have been on the books for more than five years at the corporate level or country level. All of the Company’s proved reserves are in the United States. At the field level, only at the North Lost Hills Field in Kern County, California, does the Company have a material concentration of undeveloped reserves that have been on the books for more than five years. The Company has reduced the concentration of undeveloped reserves in this field from 61% of total field level reserves at September 30, 2005 to 24% of total field level reserves at September 30, 2010. The Company has been actively drilling undeveloped locations in this field for four out of the past five years, drilling 53 undeveloped locations and converting 3.1 million barrels of proved reserves from undeveloped to developed reserves. The undeveloped reserves in this field represent less than 2% of the Company’s proved reserves at the corporate level. The Company is committed to drilling the remaining proved undeveloped locations within five years of being recorded as PUD reserves. At September 30, 2010, the Company had delivery commitments of 34 Bcf. The Company expects to meet those commitments through proved reserves and the future development of reserves that are currently classified as proved undeveloped reserves and does not anticipate any issues or constraints that would prevent the Company from meeting these commitments. The following is a summary of certain oil and gas information taken from Seneca’s records. All monetary amounts are expressed in U.S. dollars.

In addition to these matters, the Company is involved in other litigation and regulatory matters arising in the normal course of business. These other matters may include, for example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations or other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service, and purchased gas cost issues, among other things. While these normal-course matters could have a material effect on earnings and cash flows in the quarterly and annual period in which they are resolved, they are not expected to change materially the Company’s present liquidity position, nor are they expected to have a material adverse effect on the financial condition of the Company. PART II Item 5 Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Information regarding the market for the Company’s common equity and related stockholder matters appears under Item 12 at Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters, Item 8 at Note E — Capitalization and Short-Term Borrowings, and at Note P — Market for Common Stock and Related Shareholder Matters (unaudited). On July 1, 2010, the Company issued a total of 3,600 unregistered shares of Company common stock to the nine non-employee directors of the Company then serving on the Board of Directors of the Company, 400 shares to each such director. All of these unregistered shares were issued under the Company’s Retainer Policy for Non- Employee Directors as partial consideration for such directors’ services during the quarter ended September 30, 2010. These transactions were exempt from registration under Section 4(2) of the Securities Act of 1933, as transactions not involving a public offering.

During the quarter ended September 30, 2010, the Company did not purchase any shares of its common stock pursuant to its publicly announced share repurchase program. Of the 180,809 shares purchased other than through a publicly announced share repurchase program, 26,277 were purchased for the Company’s 401(k) plans and 154,532 were purchased as a result of shares tendered to the Company by holders of stock options or shares of restricted stock. (b) In December 2005, the Company’s Board of Directors authorized the repurchase of up to eight million shares of the Company’s common stock. The Company completed the repurchase of the eight million shares during 2008. In September 2008, the Company’s Board of Directors authorized the repurchase of an additional eight million shares of the Company’s common stock. The Company, however, stopped 24 repurchasing shares after September 17, 2008 in light of the unsettled nature of the credit markets. Since that time, the Company has increased its emphasis on Marcellus Shale development and pipeline expansion. As such, the Company does not anticipate repurchasing any shares in the near future.

Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations OVERVIEW The Company is a diversified energy company and reports financial results for four business segments. Refer to Item 1, Business, for a more detailed description of each of the segments. This Item 7, MD&A, provides information concerning: 1. The critical accounting estimates of the Company; 2. Changes in revenues and earnings of the Company under the heading, “Results of Operations;” 26 3. Operating, investing and financing cash flows under the heading “Capital Resources and Liquidity;” 4. Off-Balance Sheet Arrangements; 5. Contractual Obligations; and 6. Other Matters, including: (a) 2010 and projected 2011 funding for the Company’s pension and other post-retirement benefits, (b) realizability of deferred tax assets, (c) disclosures and tables concerning market risk sensitive instruments, (d) rate and regulatory matters in the Company’s New York, Pennsylvania and FERC regulated jurisdictions, (e) environmental matters, and (f) new authoritative accounting and financial reporting guidance. The information in MD&A should be read in conjunction with the Company’s financial statements in Item 8 of this report. For the year ended September 30, 2010 compared to the year ended September 30, 2009, the Company experienced an increase in earnings of $125.2 million. Earnings from continuing operations increased $115.6 million and earnings from discontinued operations increased $9.6 million. From a continuing operations perspective, the earnings increase was primarily driven by the non-recurrence of an impairment charge of $182.8 million ($108.2 million after tax) recorded in the Exploration and Production segment during the year ended September 30, 2009. In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Such costs are subject to a quarterly ceiling test prescribed by SEC Regulation S-X Rule 4-10 that determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. At December 31, 2008, due to significant declines in crude oil and natural gas commodity prices (and using the SEC full cost rules then in effect), the book value of the Company’s oil and gas properties exceeded the ceiling, resulting in the impairment charge mentioned above. For further discussion of the ceiling test results at September 30, 2010 and a sensitivity analysis to changes in crude oil and natural gas commodity prices, refer to the Critical Accounting Estimates section below. For further discussion of the Company’s earnings, refer to the Results of Operations section below. The Company continues to focus on the development of its Marcellus Shale acreage in the Appalachian region of its Exploration and Production segment. The Marcellus Shale is a Middle Devonian-age geological shale formation that is present nearly a mile or more below the surface in the Appalachian region of the United States, including much of Pennsylvania and southern New York. Due to the depth at which this formation is found, drilling and completion costs, including the drilling and completion of horizontal wells with hydraulic fracturing, are very expensive. However, independent geological studies have indicated that this formation could yield natural gas reserves measured in the trillions of cubic feet. The Company controls approximately 745,000 net acres within the Marcellus Shale area, with a majority of the acreage held in fee, carrying no royalty and no lease expirations. The Company’s reserve base has grown substantially from development in the Marcellus Shale. Natural gas proved developed and undeveloped reserves in the Appalachian region have increased from 150 Bcf at September 30, 2009 to 331 Bcf at September 30, 2010. With this in mind, and with a natural desire to realize the value of these assets in a responsible and orderly fashion, the Company has spent significant amounts of capital in this region. For the year ended September 30, 2010, the Company spent $332.4 million towards the development of the Marcellus Shale. This included paying $71.8 million in March 2010 for two tracts of leasehold acreage (consisting of approximately 18,000 net acres) in Tioga and Potter Counties in Pennsylvania. These tracts are geologically and geographically similar to the Company’s existing Marcellus Shale acreage in the area, and will help the Company continue its developmental drilling program. The Company has engaged Jefferies & Company to explore joint-venture opportunities across its Marcellus Shale acreage in its Exploration and Production segment. It is the Company’s goal to ramp up Marcellus Shale development faster than its current plans. By entering into a joint-venture agreement, the Company expects to enhance shareholder value by shifting a significant portion of the early drilling costs to a minority-interest partner while still allowing the Company to continue operating across most of its acreage. The Company’s position in the Marcellus Shale provides a competitive advantage for a potential joint- venture partner as a majority of the acreage is held in fee, carrying no royalty and no lease expirations, and large, 27 contiguous acreage blocks allow for operating- and cost-efficiency through multi-well pad drilling. The Company will forgo any joint-venture opportunities that do not enhance shareholder value when compared to its current growth plans. Coincident with the development of its Marcellus Shale acreage, the Company’s Pipeline and Storage segment is building pipeline gathering and transmission facilities to connect Marcellus Shale production with existing pipelines in the region and is pursuing the development of additional pipeline and storage capacity in order to meet anticipated demand for the large amount of Marcellus Shale production expected to come on-line in the months and years to come. Two of the projects, the Tioga County Extension Project and the Northern Access expansion project, are considered significant for Empire and Supply Corporation. Both projects are designed to receive natural gas produced from the Marcellus Shale and transport it to Canada and the Northeast United States to meet growing demand in those areas. During the past year, Empire and Supply Corporation have experienced a decline in the volumes of natural gas received at the Canada/United States border at the Niagara River to be shipped across their systems. The historical price advantage for gas sold at the Niagara import points has declined as production in the Canadian producing regions has declined or been diverted to other demand areas, and as production from new shale plays has increased in the United States. This factor has been causing shippers to seek alternative gas supplies and consequently alternative transportation routes. Empire and Supply Corporation have seen transportation volumes decrease as a result of this situation. The Tioga County Extension Project and the Northern Access expansion project are designed to provide an alternative gas supply source for the customers of Empire and Supply Corporation. These projects, which are discussed more completely in the Investing Cash Flow section that follows, will involve significant capital expenditures. From a capital resources perspective, the Company has been able to meet its capital expenditure needs for all of the above projects by using cash from operations. The Company had $395.2 million in Cash and Temporary Cash Investments at September 30, 2010, as shown on the Company’s Consolidated Balance Sheet. For fiscal 2011, the Company expects that it will be able to use cash on hand and cash from operations as its first means of financing capital expenditures, with short-term borrowings being its next source of funding. It is not expected that long-term financing will be required to meet capital expenditure needs until the later part of fiscal 2011 or in fiscal 2012. The possibility of environmental risks associated with a well completion technology referred to as hydraulic fracturing continues to be debated. In Pennsylvania, where the Company is focusing its Marcellus Shale development efforts, the permitting and regulatory processes seem to strike a balance between the environmental concerns associated with hydraulic fracturing and the benefits of increased natural gas production. Hydraulic fracturing is a well stimulation technique that has been used for many years, and in the Company’s experience, one that the Company believes has little impact to the environment. Nonetheless, the potential for increased state or federal regulation of hydraulic fracturing could impact future costs of drilling in the Marcellus Shale and lead to operational delays or restrictions. There is also the risk that drilling could be prohibited on certain acreage that is prospective for the Marcellus Shale. For example, New York State currently has a moratorium in place that prevents hydraulic fracturing of new horizontal wells in the Marcellus Shale. However, due to the small amount of Marcellus Shale acreage owned by the Company in New York State, the moratorium is not expected to have a significant impact on the Company’s plans for Marcellus Shale development. Please refer to the Risk Factors section above for further discussion. On September 1, 2010, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana. Those operations consisted of short distance landfill gas pipeline companies engaged in the purchase, sale and transportation of landfill gas. The Company’s landfill gas operations were maintained under the Company’s wholly-owned subsidiary, Horizon LFG. This sale resulted in a $6.3 million gain, net of tax. The decision to sell was based on progressing the Company’s strategy of divesting its smaller, non-core assets in order to focus on its core businesses, including the development of the Marcellus Shale and the construction of key pipeline infrastructure projects throughout the Appalachian region. As a result of the decision to sell the landfill gas operations, the Company began presenting those operations as discontinued operations in September 2010. On September 17, 2010, the Company completed the sale of its sawmill in Marienville, Pennsylvania, including approximately 23 million board feet of logs and timber consisting of yard inventory along with 28 unexpired timber cutting contracts and certain land and timber holdings designed to provide the purchaser with a supply of logs for the mill. Despite this sale, the Company has retained substantially all of its land and timber holdings, along with mineral rights on land to be sold. The Company will maintain a forestry operation; however, as part of this change in focus, the Company will no longer be processing lumber products. The Company received proceeds of approximately $15.8 million from the sale. In addition, the purchaser assumed approximately $7.4 million in payment obligations under the Company’s timber cutting contracts with various timber suppliers. In addition to the 23 million board feet mentioned above, the Company expects to sell an additional 17 million board feet of logs to the purchaser over a five-year period, during which time the Company anticipates receiving up to an additional $10 million in proceeds. There was not a material impact to earnings from this sale. CRITICAL ACCOUNTING ESTIMATES The Company has prepared its consolidated financial statements in conformity with GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the event estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. The following is a summary of the Company’s most critical accounting estimates, which are defined as those estimates whereby judgments or uncertainties could affect the application of accounting policies and materially different amounts could be reported under different conditions or using different assumptions. For a complete discussion of the Company’s significant accounting policies, refer to Item 8 at Note A — Summary of Significant Accounting Policies. Oil and Gas Exploration and Development Costs. In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Under this accounting methodology, all costs associated with property acquisition, exploration and development activities are capitalized, including internal costs directly identified with acquisition, exploration and development activities. The internal costs that are capitalized do not include any costs related to production, general corporate overhead, or similar activities. The Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. The Company believes that determining the amount of the Company’s proved reserves is a critical accounting estimate. Proved reserves are estimated quantities of reserves that, based on geologic and engineering data, appear with reasonable certainty to be producible under existing economic and operating conditions. Such estimates of proved reserves are inherently imprecise and may be subject to substantial revisions as a result of numerous factors including, but not limited to, additional development activity, evolving production history and continual reassessment of the viability of production under varying economic conditions. The estimates involved in determining proved reserves are critical accounting estimates because they serve as the basis over which capitalized costs are depleted under the full cost method of accounting (on a units-of-production basis). Unproved properties are excluded from the depletion calculation until proved reserves are found or it is determined that the unproved properties are impaired. All costs related to unproved properties are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is transferred to the pool of capitalized costs being amortized. In addition to depletion under the units-of-production method, proved reserves are a major component in the SEC full cost ceiling test. The full cost ceiling test is an impairment test prescribed by SEC Regulation S-X Rule 4-10. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of 10%, which is computed by applying an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the latest balance sheet, less 29 estimated future expenditures, plus (b) the cost of unevaluated properties not being depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. The estimates of future production and future expenditures are based on internal budgets that reflect planned production from current wells and expenditures necessary to sustain such future production. The amount of the ceiling can fluctuate significantly from period to period because of additions to or subtractions from proved reserves and significant fluctuations in oil and gas prices. The ceiling is then compared to the capitalized cost of oil and gas properties less accumulated depletion and related deferred income taxes. If the capitalized costs of oil and gas properties less accumulated depletion and related deferred taxes exceeds the ceiling at the end of any fiscal quarter, a non-cash impairment must be recorded to write down the book value of the reserves to their present value. This non-cash impairment cannot be reversed at a later date if the ceiling increases. It should also be noted that a non-cash impairment to write down the book value of the reserves to their present value in any given period causes a reduction in future depletion expense. At September 30, 2010, the ceiling exceeded the book value of the Company’s oil and gas properties by approximately $269.6 million. The 12-month average of the first day of the month price for crude oil for each month during 2010, based on posted Midway Sunset prices, was $69.64 per Bbl. The 12-month average of the first day of the month price for natural gas for each month during 2010, based on the quoted Henry Hub spot price for natural gas, was $4.41 per MMBtu. (Note — Because actual pricing of the Company’s various producing properties varies depending on their location and hedging, the actual various prices received for such production is utilized to calculate the ceiling, rather than the Midway Sunset and Henry Hub prices, which are only indicative of 12-month average prices for 2010.) If natural gas prices used in the ceiling test calculation at September 30, 2010 had been $1 per MMBtu lower, the ceiling would have exceeded the book value of the Company’s oil and gas properties by approximately $152.9 million. If crude oil prices used in the ceiling test calculation at September 30, 2010 had been $5 per Bbl lower, the ceiling would have exceeded the book value of the Company’s oil and gas properties by approximately $221.6 million. If both natural gas and crude oil prices used in the ceiling test calculation at September 30, 2010 were lower by $1 per MMBtu and $5 per Bbl, respectively, the ceiling would have exceeded the book value of the Company’s oil and gas properties by approximately $104.8 million. These calculated amounts are based solely on price changes and do not take into account any other changes to the ceiling test calculation. It is difficult to predict what factors could lead to future impairments under the SEC’s full cost ceiling test. As discussed above, fluctuations in or subtractions from proved reserves and significant fluctuations in oil and gas prices have an impact on the amount of the ceiling at any point in time. In accordance with the current authoritative guidance for asset retirement obligations, the Company records an asset retirement obligation for plugging and abandonment costs associated with the Exploration and Production segment’s crude oil and natural gas wells and capitalizes such costs in property, plant and equipment (i.e. the full cost pool). Under the current authoritative guidance for asset retirement obligations, since plugging and abandonment costs are already included in the full cost pool, the units-of-production depletion calculation excludes from the depletion base any estimate of future plugging and abandonment costs that are already recorded in the full cost pool. As discussed above, the full cost method of accounting provides a ceiling to the amount of costs that can be capitalized in the full cost pool. In accordance with current authoritative guidance, since the full cost pool includes an amount associated with plugging and abandoning the wells, as discussed in the preceding paragraph, the calculation of the full cost ceiling no longer reduces the future net cash flows from proved oil and gas reserves by an estimate of plugging and abandonment costs. Regulation. The Company is subject to regulation by certain state and federal authorities. The Company, in its Utility and Pipeline and Storage segments, has accounting policies which conform to the FASB authoritative guidance regarding accounting for certain types of regulations, and which are in accordance with the accounting requirements and ratemaking practices of the regulatory authorities. The application of these accounting policies allows the Company to defer expenses and income on the balance sheet as regulatory assets and liabilities when it is probable that those expenses and income will be allowed in the ratesetting process in a period different from the period in which they would have been reflected in the income statement by an unregulated company. These deferred regulatory assets and liabilities are then flowed through the income statement in the period in which the same amounts are reflected in rates. Management’s assessment of the 30 probability of recovery or pass through of regulatory assets and liabilities requires judgment and interpretation of laws and regulatory commission orders. If, for any reason, the Company ceases to meet the criteria for application of regulatory accounting treatment for all or part of its operations, the regulatory assets and liabilities related to those portions ceasing to meet such criteria would be eliminated from the balance sheet and included in the income statement for the period in which the discontinuance of regulatory accounting treatment occurs. Such amounts would be classified as an extraordinary item. For further discussion of the Company’s regulatory assets and liabilities, refer to Item 8 at Note C — Regulatory Matters. Accounting for Derivative Financial Instruments. The Company, in its Exploration and Production segment, Energy Marketing segment, and Pipeline and Storage segment, uses a variety of derivative financial instruments to manage a portion of the market risk associated with fluctuations in the price of natural gas and crude oil. These instruments are categorized as price swap agreements and futures contracts. In accordance with the authoritative guidance for derivative instruments and hedging activities, the Company accounted for these instruments as effective cash flow hedges or fair value hedges. Gains or losses associated with the derivative financial instruments are matched with gains or losses resulting from the underlying physical transaction that is being hedged. To the extent that the derivative financial instruments would ever be deemed to be ineffective based on the effectiveness testing, mark-to-market gains or losses from the derivative financial instruments would be recognized in the income statement without regard to an underlying physical transaction. The Company uses both exchange-traded and non exchange-traded derivative financial instruments. The Company adopted the authoritative guidance for fair value measurements during the quarter ended December 31, 2008. As such, the fair value of such derivative financial instruments is determined under the provisions of this guidance. The fair value of exchange traded derivative financial instruments is determined from Level 1 inputs, which are quoted prices in active markets. The Company determines the fair value of non exchange-traded derivative financial instruments based on an internal model, which uses both observable and unobservable inputs other than quoted prices. These inputs are considered Level 2 or Level 3 inputs. All derivative financial instrument assets and liabilities are evaluated for the probability of default by either the counterparty or the Company. Credit reserves are applied against the fair values of such assets or liabilities. Refer to the “Market Risk Sensitive Instruments” section below for further discussion of the Company’s derivative financial instruments. Pension and Other Post-Retirement Benefits. The amounts reported in the Company’s financial statements related to its pension and other post-retirement benefits are determined on an actuarial basis, which uses many assumptions in the calculation of such amounts. These assumptions include the discount rate, the expected return on plan assets, the rate of compensation increase and, for other post-retirement benefits, the expected annual rate of increase in per capita cost of covered medical and prescription benefits. The Company utilizes a yield curve model to determine the discount rate. The yield curve is a spot rate yield curve that provides a zero- coupon interest rate for each year into the future. Each year’s anticipated benefit payments are discounted at the associated spot interest rate back to the measurement date. The discount rate is then determined based on the spot interest rate that results in the same present value when applied to the same anticipated benefit payments. The expected return on plan assets assumption used by the Company reflects the anticipated long-term rate of return on the plan’s current and future assets. The Company utilizes historical investment data, projected capital market conditions, and the plan’s target asset class and investment manager allocations to set the assumption regarding the expected return on plan assets. Changes in actuarial assumptions and actuarial experience, including deviations between actual versus expected return on plan assets, could have a material impact on the amount of pension and post-retirement benefit costs and funding requirements experienced by the Company. However, the Company expects to recover substantially all of its net periodic pension and other post-retirement benefit costs attributable to employees in its Utility and Pipeline and Storage segments in accordance with the applicable regulatory commission authorization. For financial reporting purposes, the difference between the amounts of pension cost and post-retirement benefit cost recoverable in rates and the amounts of such costs as determined under applicable accounting principles is recorded as either a regulatory asset or liability, as appropriate, as discussed above under “Regulation.” Pension and post-retirement benefit costs for the Utility 31 and Pipeline and Storage segments, as determined under the authoritative guidance for pensions and postretirement benefits, represented 93% of the Company’s total pension and post-retirement benefit costs for the years ended September 30, 2010 and 2009. Changes in actuarial assumptions and actuarial experience could also have an impact on the benefit obligation and the funded status related to the Company’s pension and other post-retirement benefits and could impact the Company’s equity. For example, the discount rate was changed from 5.50% in 2009 to 4.75% in 2010. The change in the discount rate from 2009 to 2010 increased the Retirement Plan projected benefit obligation by $75.1 million and the accumulated post-retirement benefit obligation by $39.4 million. Other examples include actual versus expected return on plan assets, which has an impact on the funded status of the plans, and actual versus expected benefit payments, which has an impact on the pension plan projected benefit obligation and the accumulated post-retirement benefit obligation. For 2010, the actual return on plan assets exceeded the expected return, which improved the funded status of the Retirement Plan ($3.3 million) as well as the VEBA trusts and 401(h) accounts ($4.1 million). The actual versus expected benefit payments for 2010 caused a decrease of $4.3 million to the accumulated post-retirement benefit obligation. In calculating the projected benefit obligation for the Retirement Plan and the accumulated post-retirement obligation, the actuary takes into account the average remaining service life of active participants. The average remaining service life of active participants is 9 years for the Retirement Plan and 8 years for those eligible for other post-retirement benefits. For further discussion of the Company’s pension and other post-retirement benefits, refer to Other Matters in this Item 7, which includes a discussion of funding for the current year, and to Item 8 at Note H — Retirement Plan and Other Post Retirement Benefits. RESULTS OF OPERATIONS EARNINGS 2010 Compared with 2009 The Company’s earnings were $225.9 million in 2010 compared with earnings of $100.7 million in 2009. As previously discussed, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana in September 2010. Accordingly, all financial results for those operations, which are part of the All Other category, have been presented as discontinued operations. The Company’s earnings from continuing operations were $219.1 million in 2010 compared with $103.5 million in 2009. The Company’s earnings from discontinued operations were $6.8 million in 2010 compared to a loss of $2.8 million in 2009. The increase in earnings from continuing operations of $115.6 million is primarily the result of higher earnings in the Exploration and Production segment. The Utility and Energy Marketing segments, as well as the All Other category, also contributed to the increase in earnings. Lower earnings in the Pipeline and Storage segment and a higher loss in the Corporate category slightly offset these increases. The increase in earnings from discontinued operations primarily resulted from the gain on the sale of the Company’s landfill gas operations recognized in 2010 as well as the non-recurrence of $2.8 million of impairment charges recognized in 2009 related to certain landfill gas assets. In the discussion that follows, note that all amounts used in the earnings discussions are after-tax amounts, unless otherwise noted. Earnings from continuing operations and discontinued operations were impacted by the following event in 2010 and several events in 2009, including: 2010 Event (cid:129) A $6.3 million gain on the sale of the Company’s landfill gas operations, which was completed in September 2010. This amount is included in earnings from discontinued operations. 2009 Events (cid:129) A non-cash $182.8 million impairment charge ($108.2 million after tax) recorded during the quarter ended December 31, 2008 for the Exploration and Production segment’s oil and gas producing properties; 32 (cid:129) A $2.8 million impairment in the value of certain landfill gas assets; (cid:129) A $1.1 million impairment in the value of the Company’s 50% investment in ESNE (recorded in the All Other category), a limited liability company that owns an 80-megawatt, combined cycle, natural gas- fired power plant in the town of North East, Pennsylvania; and (cid:129) A $2.3 million death benefit gain on life insurance policies recognized in the Corporate category. 2009 Compared with 2008 The Company’s earnings were $100.7 million in 2009 compared with earnings of $268.7 million in 2008. The Company’s earnings from continuing operations were $103.5 million in 2009 compared with $266.9 million in 2008. The Company recorded a loss from discontinued operations of $2.8 million in 2009 compared with earnings from discontinued operations of $1.8 million in 2008. Discontinued operations in 2009 and 2008 consisted of the Company’s landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana. The decrease in earnings from continuing operations of $163.4 million is primarily the result of lower earnings in the Exploration and Production, Pipeline and Storage and Utility segments and the All Other category, slightly offset by a lower loss in the Corporate category and higher earnings in the Energy Marketing segment, as shown in the table below. The loss from discontinued operations in 2009 compared to earnings from discontinued operations in 2008 reflects the recognition of $2.8 million of impairment charges in 2009 related to certain landfill gas assets. Earnings from continuing operations and discontinued operations were impacted by the 2009 events discussed above and the following 2008 event: 2008 Event (cid:129) A $0.6 million gain in the All Other category associated with the sale of Horizon Power’s gas-powered turbine.

This decrease largely resulted from a $315.6 million decrease in retail gas sales revenues, a $1.8 million decrease in transportation revenues, and a $1.2 million decrease in other operating revenues. These were partially offset by a $25.4 million increase in off-system sales revenue. The decrease in retail gas sales revenues of $315.6 million was largely a function of warmer weather and lower gas costs (subject to certain timing variations, gas costs are recovered dollar for dollar in revenues). The recovery of lower gas costs resulted from a lower cost of purchased gas combined with the refunding of previously over-recovered purchased gas costs. See further discussion of purchased gas below under the heading “Purchased Gas.” The increase in off-system sales revenues of $25.4 million was largely due to the Utility segment not engaging in off-system sales from November 2008 through October 2009. This was due to Order No. 717 (“Final Rule”), which was issued by the FERC on October 16, 2008. The Final Rule seemingly held that a local distribution company making off-system sales on unaffiliated pipelines would be engaging in “marketing” that would require Distribution Corporation to substantially modify its operations in order to assure compliance with the FERC’s standards of conduct. Accordingly, pending clarification of this issue from the FERC, as of November 1, 2008, Distribution Corporation ceased off-system sales activities. On October 15, 2009, the FERC released Order No. 717-A, which clarified that a local distribution company making off-system sales of gas that has been transported on non-affiliated pipelines is not subject to the FERC standards of conduct. In light of and in reliance on this clarification, Distribution Corporation determined that it could resume engaging in off-system sales on non- affiliated pipelines. Such off-system sales resumed in November 2009. Due to profit sharing with retail customers, the margins resulting from off-system sales are minimal and there was not a material impact to earnings. The decrease in transportation revenues of $1.8 million was primarily due to warmer weather and the resulting decrease in transportation volumes for residential and commercial customers. While there was a slight increase in transportation volumes of 0.4 Bcf for all revenue classes, this was largely due to an increase in throughput for large industrial customers. Margins associated with large industrial customers do not have a significant impact on transportation revenues. The decrease in other operating revenues of $1.2 million is largely due to a decrease in late payment revenue, caused by a decrease in gas costs. 2009 Compared with 2008 Operating revenues for the Utility segment decreased $97.2 million in 2009 compared with 2008. This decrease largely resulted from a $54.5 million decrease in off-system sales revenue (see discussion below), a $33.6 million decrease in retail gas sales revenues, a $2.4 million decrease in transportation revenues, and a $6.7 million decrease in other operating revenues. The decrease in retail gas sales revenues of $33.6 million was largely a function of the recovery of lower gas costs (subject to certain timing variations, gas costs are recovered dollar for dollar in revenues). The recovery of lower gas costs resulted from a much lower cost of purchased gas. See further discussion of purchased gas below under the heading “Purchased Gas.” The decrease in transportation revenues of $2.4 million was primarily due to a 4.5 Bcf decrease in transportation throughput, largely the result of customer conservation efforts and the poor economy. In the New York jurisdiction, the NYPSC issued an order providing for an annual rate increase of $1.8 million beginning December 28, 2007. As part of this rate order, a rate design change was adopted that shifts a greater amount of cost recovery into the minimum bill amount, thus spreading the recovery of such costs more evenly throughout the year. As a result of this rate order, retail and transportation revenues for 2009 were $2.2 million lower than revenues for 2008. The Utility segment had off-system sales revenues of $3.7 million and $58.2 million for 2009 and 2008, respectively. Due to profit sharing with retail customers, the margins resulting from off-system sales are minimal and there was not a material impact to margins in 2009 and 2008. The decrease in off-system sales revenue stemmed from Order No. 717 (“Final Rule”), as discussed above. 35 The decrease in other operating revenues of $6.7 million is largely related to amounts recorded in 2008 pursuant to rate settlements approved by the NYPSC. In accordance with these settlements, Distribution Corporation was allowed to utilize certain refunds from upstream pipeline companies and certain other credits (referred to as the “cost mitigation reserve”) to offset certain specific expense items. In 2008, Distribution Corporation utilized $5.6 million of the cost mitigation reserve, which increased other operating revenues, to recover previous undercollections of pension expenses. In 2009, Distribution Corporation utilized only $0.2 million of the cost mitigation reserve. The impact of this $5.4 million decrease in other operating revenues was offset by an equal decrease to operation and maintenance expense (thus there was no earnings impact). Purchased Gas The cost of purchased gas is the Company’s single largest operating expense. Annual variations in purchased gas costs are attributed directly to changes in gas sales volumes, the price of gas purchased and the operation of purchased gas adjustment clauses. Distribution Corporation recorded $428.4 million, $713.2 million and $800.5 million of Purchased Gas Expense during 2010, 2009 and 2008, respectively. Under its purchased gas adjustment clauses in New York and Pennsylvania, Distribution Corporation is not allowed to profit from fluctuations in gas costs. Purchased gas expense recorded on the consolidated income statement matches the revenues collected from customers, a component of Operating Revenues on the consolidated income statement. Under mechanisms approved by the NYPSC in New York and the PaPUC in Pennsylvania, any difference between actual purchased gas costs and what has been collected from the customer is deferred on the consolidated balance sheet as either an asset, Unrecovered Purchased Gas Costs, or a liability, Amounts Payable to Customers. These deferrals are subsequently collected from the customer or passed back to the customer, subject to review by the NYPSC and the PaPUC. Absent disallowance of full recovery of Distribution Corporation’s purchased gas costs, such costs do not impact the profitability of the Company. Purchased gas costs impact cash flow from operations due to the timing of recovery of such costs versus the actual purchased gas costs incurred during a particular period. Distribution Corporation’s purchased gas adjustment clauses seek to mitigate this impact by adjusting revenues on either a quarterly or monthly basis. Currently, Distribution Corporation has contracted for long-term firm transportation capacity with Supply Corporation, Empire and six other upstream pipeline companies, for long-term gas supplies with a combination of producers and marketers, and for storage service with Supply Corporation and two nonaffiliated companies. In addition, Distribution Corporation satisfies a portion of its gas requirements through spot market purchases. Changes in wellhead prices have a direct impact on the cost of purchased gas. Distribution Corporation’s average cost of purchased gas, including the cost of transportation and storage, was $7.13 per Mcf in 2010, a decrease of 13% from the average cost of $8.17 per Mcf in 2009. The average cost of purchased gas in 2009 was 27% lower than the average cost of $11.23 per Mcf in 2008. Additional discussion of the Utility segment’s gas purchases appears under the heading “Sources and Availability of Raw Materials” in Item 1. Earnings 2010 Compared with 2009 The Utility segment’s earnings in 2010 were $62.5 million, an increase of $3.8 million when compared with earnings of $58.7 million in 2009. In the New York jurisdiction, earnings increased by $1.8 million. The positive earnings impact associated with lower operating expenses of $1.5 million (primarily a decrease in bad debt expense slightly offset by an increase in personnel costs) and routine regulatory adjustments ($1.4 million) were partially offset by a $1.2 million decrease in late payment revenue (due to lower gas costs) and higher income tax expense of $0.3 million. The impact of weather on the Utility segment’s New York rate jurisdiction is tempered by a weather normalization clause (WNC). The WNC, which covers the eight-month period from October through May, has had a stabilizing effect on earnings for the New York rate jurisdiction. In addition, in periods of colder than normal weather, the WNC benefits the Utility segment’s New York customers. For 2010, the WNC preserved 36 earnings of approximately $1.3 million, as the weather was warmer than normal. For 2009, the WNC reduced earnings by approximately $0.2 million, as the weather was colder than normal. In the Pennsylvania jurisdiction, earnings increased by $2.0 million. The positive earnings impact associated with a lower effective tax rate ($5.1 million) and lower operating expenses of $2.8 million were the main factors in the earnings increase. The effective tax rate impact is attributable to a lower state income tax expense in 2010 as a result of the pass-back to customers of over-collected gas costs. The decrease in operating expenses was primarily attributable to a decrease in bad debt expense. These factors were partially offset by lower usage per account ($2.1 million), higher interest expense ($2.1 million), warmer weather ($0.8 million) and routine regulatory true-up adjustments ($0.2 million). The phrase “usage per account” refers to average gas consumption per account after factoring out any impact that weather may have had on consumption. The increase in interest expense was partially due to the Company’s April 2009 debt issuance that was issued at a significantly higher interest rate than the debt that had matured in March 2009. In addition, accrued interest on deferred gas costs increased as a result of the over-recovery of gas costs during fiscal 2009. 2009 Compared with 2008 The Utility segment’s earnings in 2009 were $58.7 million, a decrease of $2.8 million when compared with earnings of $61.5 million in 2008. In the New York jurisdiction, earnings decreased by $3.0 million. This was primarily due to an increase in interest expense ($2.9 million) stemming from the borrowing by the New York jurisdiction of Distribution Corporation of a portion of the Company’s April 2009 debt issuance. The April 2009 debt was issued at a significantly higher interest rate than the interest rates on debt that had matured in March 2009. The negative earnings impact of the December 28, 2007 rate order discussed above ($1.4 million) and routine regulatory adjustments ($0.7 million) also contributed to the decrease. The decrease was partially offset by a $2.6 million overall reduction in operating expenses (mostly other post-retirement benefits and pension expense). In 2009, the WNC reduced earnings by approximately $0.2 million, as the weather was colder than normal. In 2008, the WNC preserved earnings of approximately $2.5 million, as the weather was warmer than normal. In the Pennsylvania jurisdiction, earnings increased by $0.2 million. This was primarily due to the positive earnings impact of colder weather ($2.1 million), routine regulatory adjustments ($0.5 million) and lower operating expenses ($0.9 million). A decrease in normalized usage per account ($2.3 million), a higher effective tax rate ($1.4 million) and an increase in interest expense ($0.2 million) partially offset these increases. The phrase “usage per account” refers to the average gas consumption per customer account after factoring out any impact that weather may have had on consumption. 37 PIPELINE AND STORAGE Revenues Pipeline and Storage Operating Revenues Firm Transportation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $139,324 1,863 Interruptible Transportation . . . . . . . . . . . . . . . . . . . . . . . . . 2010 Year Ended September 30 2009 (Thousands) $139,034 3,175 $122,321 4,330 2008 Firm Storage Service . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The decrease was due to a decrease in interruptible transportation revenues of $1.3 million largely due to a decrease in the gathering rate under Supply Corporation’s tariff. Also contributing to the decrease was a decrease in cashout revenues of $0.3 million (reported as a part of other revenue in the table above). Cashout revenues are completely offset by purchased gas expense and as a result have no impact on earnings. Offsetting the decrease was an increase in efficiency gas revenues of $1.3 million (reported as a part of other revenue in the table above) due to higher efficiency gas volumes and a significantly lower efficiency gas inventory write down in 2010 versus 2009. These increases to efficiency gas revenues were partially offset by lower gas prices and a lower gain, period over period, on the sale of retained efficiency gas volumes held in inventory. Under Supply Corporation’s tariff with shippers, Supply Corporation is allowed to retain a set percentage of shipper-supplied gas to cover compressor fuel costs and for other operational purposes. To the extent that Supply Corporation does not need all of the gas to cover such operational needs, it is allowed to keep the excess gas as inventory. That inventory is later sold to buyers on the open market. The excess gas that is retained as inventory, as well as any gains resulting from the sale of such inventory, represent efficiency gas revenue to Supply Corporation. Also offsetting the decrease in revenues was an increase in firm transportation revenues of $0.3 million. This increase was primarily the result of higher revenues from the Empire Connector, which was placed in service in December 2008, partially offset by a reduction in the level of short-term contracts entered into by shippers period over period as such shippers utilized lower priced pipeline transportation routes. Transportation volume decreased by 50.8 Bcf in 2010 as compared with 2009. These decreases were largely due to shippers seeking alternative lower priced gas supply (and in some cases, not renewing short-term transportation contracts) combined with warmer weather and lower industrial demand. The reason shippers are seeking lower priced gas supply is primarily because of the relatively higher price of natural gas supplies available at the United States/Canadian border at the Niagara River near Buffalo, New York compared to the lower pricing for supplies available at Leidy, Pennsylvania. Empire’s proposed Tioga County Extension Project and Supply Corporation’s “Northern Access” expansion project, both of which are discussed in the Investing Cash Flow 38 section that follows, are designed to utilize that available pipeline capacity by receiving natural gas produced from the Marcellus Shale and transporting it to Canada and the Northeast United States where demand has been growing. Much of the impact of lower volumes is offset by the straight fixed-variable rate design utilized by Supply Corporation and Empire. However, this rate design does not protect Supply Corporation or Empire in situations where shippers do not contract for that capacity at the same quantity and rate. In that situation, Supply Corporation or Empire can propose revised rates and services in a rate case at the FERC. 2009 Compared with 2008 Operating revenues for the Pipeline and Storage segment increased $2.7 million in 2009 as compared with 2008. The increase was primarily due to a $15.6 million increase in transportation revenue primarily due to higher revenues from the Empire Connector and new contracts for transportation service. Partially offsetting this increase, efficiency gas revenues decreased $11.5 million. The majority of this decrease was due to significantly lower gas prices in 2009 as compared to 2008. Earnings 2010 Compared with 2009 The Pipeline and Storage segment’s earnings in 2010 were $36.7 million, a decrease of $10.7 million when compared with earnings of $47.4 million in 2009. The decrease in earnings is primarily due to a decrease in the allowance for funds used during construction ($2.3 million), higher operating costs ($4.5 million), higher property taxes ($2.0 million), higher interest expense ($3.1 million) and higher depreciation expense ($0.5 million). Lower transportation revenues of $0.7 million, as discussed above, also contributed to the earnings decrease. The decrease in allowance for funds used during construction (equity component) is a result of the construction of the Empire Connector, which was completed and placed in service on December 10, 2008. The increase in operating expenses can primarily be attributed to higher pension expense, higher personnel costs, and an increase in corrosion logging expenses associated with Supply Corporation’s storage wells. The increase in property taxes is primarily a result of additional property taxes and higher payments in lieu of taxes associated with the Empire Connector. The increase in interest expense can be attributed to higher debt balances and a higher average interest rate on borrowings combined with a decrease in the allowance for borrowed funds used during construction resulting from the completion of the Empire Connector. The increase in the average interest rate stems from the Company’s April 2009 debt issuance. The increase in depreciation expense is primarily the result of the Empire Connector being placed in service in December 2008. These earnings decreases were partially offset by the earnings impact associated with higher efficiency gas revenues ($0.8 million), as discussed above, and lower income tax expense ($1.4 million) due to a lower effective tax rate. 2009 Compared with 2008 The Pipeline and Storage segment’s earnings in 2009 were $47.4 million, a decrease of $6.7 million when compared with earnings of $54.1 million in 2008. The decrease was primarily due to the earnings impact associated with a decrease in efficiency gas revenues ($7.5 million), as discussed above. In addition, higher interest expense ($5.1 million), higher depreciation expense ($1.5 million), and a decrease in the allowance for funds used during construction ($2.0 million) also contributed to the decrease in earnings. The increase in interest expense can be attributed to higher debt balances and a higher average interest rate on borrowings. The increase in the average interest rate stems from the Company’s April 2009 debt issuance. The increase in depreciation expense can be attributed primarily to a revision of accumulated depreciation combined with the increased depreciation associated with placing the Empire Connector in service in December 2008. The decrease in the allowance for funds used during construction was due to completion of the Empire Connector project in December 2008. Whereas the allowance for funds used during construction related to the Empire Connector project was recorded throughout 2008, it was only recorded for three months in 2009. These earnings decreases were partially offset by the earnings impact associated with higher transportation revenues ($9.7 million), as discussed above. 39 EXPLORATION AND PRODUCTION Revenues Exploration and Production Operating Revenues Gas (after Hedging) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $183,327 242,303 Oil (after Hedging) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 29,369 Gas Processing Plant . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 820 Other . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(2) Includes low gravity oil which generally sells for a lower price. 2010 Compared with 2009 Operating revenues for the Exploration and Production segment increased $55.3 million in 2010 as compared with 2009. Gas production revenue after hedging increased $28.7 million primarily due to production increases in the Appalachian division. The increase in Appalachian natural gas production was mainly due to Marcellus Shale production that came on line during fiscal 2010, primarily in Tioga County, Pennsylvania. Increases in natural gas production were partially offset by a $0.90 per Mcf decrease in the weighted average price of gas after hedging. Oil production revenue after hedging increased $23.3 million due to an increase in the weighted average price of oil after hedging ($10.31 per Bbl), while oil production levels were slightly lower in fiscal 2010. In addition, there was a $2.9 million increase in gross processing plant revenues (net of eliminations) due to an increase in the commodity prices of residual gas and liquids sold at Seneca’s processing plants in the West Coast region. Refer to further discussion of derivative financial instruments in the “Market Risk Sensitive Instruments” section that follows. Refer to the tables above for production and price information. 2009 Compared with 2008 Operating revenues for the Exploration and Production segment decreased $84.0 million in 2009 as compared with 2008. Gas production revenue after hedging decreased $47.6 million primarily due to a $2.11 per Mcf decrease in weighted average prices after hedging. Gas production was virtually flat with the prior year as production decreases in the Gulf Coast region were substantially offset by production increases in the Appalachian region. The decrease in gas production that occurred in the Gulf Coast region (1,147 MMcf) was a result of lingering shut-ins caused by Hurricanes Edouard, Gustav and Ike in September 2008. While Seneca’s properties sustained only superficial damage from the hurricanes, two significant producing properties were shut-in for a significant portion of the current fiscal year due to repair work on third party pipelines and onshore processing facilities. One of the properties was back on line by March 31, 2009 and the other property was back on line by the end of April 2009. The increase in gas production in the Appalachian region of 1,066 MMcf resulted from additional wells drilled throughout fiscal 2008 that came on line in 2009. Oil production revenue after hedging decreased $31.9 million due to a $16.81 per barrel decrease in weighted average prices after hedging, which more than offset an increase in oil production of 303,000 barrels (primarily from the West Coast and Gulf Coast regions). In addition, there was a $5.9 million decrease in gross processing plant revenues (net of 41 eliminations) due to a reduction in the commodity prices of residual gas and liquids sold at Seneca’s processing plants in the West Coast and Appalachian regions. Refer to further discussion of derivative financial instruments in the “Market Risk Sensitive Instruments” section that follows. Refer to the tables above for production and price information. Earnings 2010 Compared with 2009 The Exploration and Production segment’s earnings for 2010 were $112.5 million, compared with a loss of $10.2 million for 2009, an increase of $122.7 million. The increase in earnings is primarily the result of the non- recurrence of an impairment charge of $108.2 million during the quarter ended December 31, 2008, as discussed above in the Overview section. Higher natural gas production and higher crude oil prices increased earnings by $36.3 million and $21.6 million, respectively. Higher processing plant revenues ($1.9 million) largely due to an increase in commodity prices of residual gas and liquids sold at Seneca’s processing plants in the West Coast region further contributed to an increase in earnings. Lower interest expense ($1.6 million) due to a lower average amount of debt outstanding and the capitalization of interest further contributed to an increase in earnings. In addition, lower general and administrative and other operating expenses ($1.2 million) increased earnings. The decrease in general and administrative and other operating expenses primarily reflects variations between actual plugging and abandonment costs incurred versus amounts previously accrued for such properties. During 2010, actual plugging and abandonment costs incurred were less than the liability that had been established for such properties, resulting in a gain. The decrease in general and administrative and other operating expenses also reflects a decrease in bad debt expense. Higher personnel costs, primarily in the Appalachian region, partially offset these decreases. Lower natural gas prices ($17.7 million) and lower crude oil production ($6.5 million) partially offset the increase in earnings. In addition, the earnings increases noted above were partially offset by higher depletion expense ($10.0 million), the earnings impact associated with higher income tax expense ($7.2 million), higher lease operating expenses ($6.1 million), and lower interest income ($0.9 million). The increase in depletion expense was primarily due to an increase in production and depletable base (largely due to increased capital spending in the Appalachian region). The increase in income tax expense in 2010 is attributable to the loss of a domestic production activities deduction for fiscal 2010, the non-recurrence of a Corporate tax benefit received in the prior year, and higher state income taxes. Lease operating expenses increased due to higher steaming costs in California, additional production properties related to the acquisition of Ivanhoe Energy’s United States oil and gas properties in July 2009, an increase in the costs associated with a higher number of producing properties in the Appalachian region, primarily within the Marcellus Shale, and higher production taxes. The reduction in interest income was largely due to lower interest rates on cash investment balances. 2009 Compared with 2008 The Exploration and Production segment’s loss for 2009 was $10.2 million, compared with earnings of $146.6 million for 2008, a decrease of $156.8 million. The decrease in earnings is primarily the result of an impairment charge of $108.2 million, as discussed above. In addition, lower crude oil prices, lower natural gas prices, and lower natural gas production decreased earnings by $36.9 million, $30.6 million, and $0.3 million, respectively, while higher crude oil production increased earnings by $16.1 million. Lower interest income ($5.5 million) and higher operating expenses ($1.7 million) further reduced earnings. In addition, there was a $3.8 million decrease in earnings caused by a reduction in the commodity prices of residual gas and liquids sold at Seneca’s processing plants in the West Coast and Appalachian regions. The decrease in interest income is due to lower interest rates and lower temporary cash investment balances. The increase in operating expenses is due to an increase in bad debt expense as a result of a customer’s bankruptcy filing, and higher personnel costs in the Appalachian region. These earnings decreases were partially offset by lower interest expense ($5.4 million), lower lease operating costs ($2.6 million), lower depletion expense ($0.9 million), and lower income tax expense ($4.2 million). The decline in interest expense is primarily due to a lower average amount of debt outstanding. The reduction in lease operating expenses is primarily due to a reduction in steam fuel costs in the West Coast region and lower production taxes in the Gulf Coast region. The decrease in depletion is primarily 42 due to a lower full cost pool balance after the impairment charge taken during the quarter ended December 31, 2008.

The decrease primarily reflects a decline in gas sales revenue due to a lower average price of natural gas that was recovered through revenues, as well as a decrease in volume sold. The decrease in volume is largely attributable to a decrease in volume sold to low-margin wholesale customers as well as fewer sales transactions undertaken at the Niagara pipeline delivery point to offset certain basis risks that the Energy Marketing segment was exposed to under certain fixed basis commodity purchase contracts for Appalachian production. Such transactions had the effect of increasing revenue and volume sold with minimal impact to earnings. 2009 Compared with 2008 Operating revenues for the Energy Marketing segment decreased $152.9 million in 2009 as compared with 2008. The decrease is primarily due to lower gas sales revenue, due to a lower average price of natural gas that was recovered through revenues. This decline was somewhat offset by an increase in volume sold. The increase in sales volume is largely attributable to colder weather as well as an increase in sales transactions undertaken at the Niagara pipeline delivery point to offset certain basis risks that the Energy Marketing segment was exposed to under certain fixed basis commodity purchase contracts for Appalachian production. Such transactions had the effect of increasing revenue and volume sold with minimal impact to earnings. Earnings 2010 Compared with 2009 The Energy Marketing segment’s earnings in 2010 were $8.8 million, an increase of $1.6 million when compared with earnings of $7.2 million in 2009. This increase was primarily attributable to higher margin of $1.4 million combined with lower income tax expense of $0.4 million. The increase in margin was primarily driven by improved average margins per Mcf, the benefit that the Energy Marketing segment derived from its contracts for storage capacity, and proceeds received as a member of a class of claimants in a class action litigation settlement. Higher operating costs of $0.1 million slightly offset the increase in earnings. The increase in operating expenses was primarily due to a June 2010 accrual for U.S. Customs merchandise processing fees that may be due for certain past gas imports from Canada, largely offset by lower bad debt expense. 43 2009 Compared with 2008 The Energy Marketing segment’s earnings in 2009 were $7.2 million, an increase of $1.3 million when compared with earnings of $5.9 million in 2008. Higher margin of $1.5 million combined with lower operating costs of $0.4 million (primarily due to a decline in bad debt expense) are responsible for the increase in earnings. These increases were partially offset by higher income tax expense of $0.4 million in 2009 as compared to 2008. The increase in margin was primarily driven by lower pipeline transportation fuel costs due to lower natural gas commodity prices, an unfavorable pipeline imbalance resolution in fiscal 2008 that did not recur in fiscal 2009, and improved average margins per Mcf, partially offset by higher pipeline reservation charges related to additional storage capacity. ALL OTHER AND CORPORATE OPERATIONS All Other and Corporate operations primarily includes the operations of Highland, Seneca’s Northeast Division, Midstream Corporation, Horizon Power, former International segment activity and corporate operations. Highland and Seneca’s Northeast Division market timber from their New York and Pennsylvania land holdings. In September 2010, the Company sold its sawmill in Marienville, Pennsylvania along with the mill’s inventory, stumpage tracts and certain land and timber acreage for approximately $15.8 million. The Company recognized a gain of approximately $0.4 million from this sale ($0.2 million net of tax). The Company continues to maintain a forestry operation, but will no longer be processing lumber products. Midstream Corporation is a Pennsylvania corporation formed to build, own and operate natural gas processing and pipeline gathering facilities in the Appalachian region. Horizon Power’s activity primarily consists of equity method investments in Seneca Energy, Model City and ESNE. Horizon Power has a 50% ownership interest in each of these entities. The income from these equity method investments is reported as Income from Unconsolidated Subsidiaries on the Consolidated Statements of Income. Seneca Energy and Model City generate and sell electricity using methane gas obtained from landfills owned by outside parties. On November 1, 2010, ESNE stopped all electricity generation operations. The turbines and other assets will be sold and the building will be dismantled. ESNE generated electricity from an 80-megawatt, combined cycle, natural gas-fired power plant in North East, Pennsylvania. In September 2010, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana for $38.0 million, recognizing a gain of $10.3 million ($6.3 million net of tax). The Company’s landfill gas operations were maintained under the Company’s wholly owned subsidiary, Horizon LFG, which owned and operated these short distance landfill gas pipeline companies. These operations are presented in the Company’s financial statements as discontinued operations. Refer to Item 8 at Note J — Discontinued Operations for further details. Earnings 2010 Compared with 2009 All Other and Corporate operations had a loss from continuing operations of $1.4 million in 2010 compared with earnings from continuing operations of $0.5 million in 2009. The overall decrease was due to higher interest expense of $3.8 million (primarily the result of higher borrowings at a higher interest rate due to the $250 million of 8.75% notes issued in April 2009), higher income tax expense of $3.7 million (due to a higher effective tax rate), higher depreciation and depletion of $2.4 million (mostly attributable to increased depletion expense due to an increase in timber harvested from Company owned lands), and higher operating expenses of $1.0 million (mostly attributable to an increase in Midstream Corporation’s operating activities). In addition, the non-recurrence of a gain resulting from a death benefit on corporate-owned life insurance policies held by the Company of $2.3 million that occurred during the quarter ended December 31, 2008 further reduced earnings. The negative earnings impact associated with items mentioned above were partially offset by higher margins of $6.5 million and higher interest income of $3.1 million. The increase in margins was mostly attributable to higher margins from log and lumber sales (partially due to the increase in timber harvested from low cost basis, Company owned lands) coupled with higher revenues from Midstream Corporation’s gathering operations. The increase in interest income was due to higher intercompany interest collected from the Company’s other operating segments as a result of the allocation of the aforementioned April 2009 debt issuance. In addition, during the quarter ended December 31, 2008, ESNE, an unconsolidated subsidiary of 44 Horizon Power, recorded an impairment charge of $3.6 million, which did not recur. Horizon Power’s 50% share of the impairment was $1.8 million ($1.1 million on an after tax basis). 2009 Compared with 2008 All Other and Corporate operations had earnings from continuing operations of $0.5 million in 2009, an increase of $1.7 million compared with a loss from continuing operations of $1.2 million for 2008. The increase was due to lower operating costs ($3.8 million), lower income tax expenses ($4.6 million), lower depreciation and depletion ($0.4 million) and higher other income ($0.7 million). In 2008, the proxy contest with New Mountain Vantage GP, L.L.C. led to an increase in operating costs, which did not recur in 2009. In addition, a gain on life insurance policies held by the Company ($2.3 million) further increased earnings. The reduction in depreciation and depletion expense is due to a decrease in timber harvested from Company owned lands. The increase in other income is primarily due to an increase in the value of corporate owned life insurance policies. These earnings increases were partially offset by higher interest expense ($3.4 million), lower income from Horizon Power’s investments in unconsolidated subsidiaries ($2.0 million), lower margins from lumber, log, and timber rights sales ($2.5 million) and lower interest income ($0.6 million). The decrease in margins from lumber, log and timber rights sales is a result of a decline in revenues due to unfavorable market conditions. The increase in interest expense was primarily the result of higher borrowings at a higher interest rate (mostly due to the $250 million of 8.75% notes that were issued in April 2009). The decrease in interest income is largely due to lower rates on cash investment balances. In addition, during 2009, ESNE, an unconsolidated subsidiary of Horizon Power, recorded an impairment charge of $3.6 million. Horizon Power’s 50% share of the impairment was $1.8 million ($1.1 million on an after tax basis). The impairment charge of $3.6 million recorded by ESNE during 2009 (as discussed above) was driven by a significant decrease in “run time” for the plant given the economic downturn and the resulting decrease in demand for electric power. Also, Horizon Power recognized a gain on the sale of a turbine ($0.6 million) during 2008 that did not recur in 2009. INTEREST INCOME Interest income was $2.0 million lower in 2010 as compared to 2009. Lower interest rates on cash investment balances was the primary factor contributing to this decrease. Interest income was $5.0 million lower in 2009 as compared to 2008. Lower cash investment balances in the Exploration and Production segment and lower interest rates on such investments were the primary factors contributing to this decrease. OTHER INCOME Other income was $4.6 million lower in 2010 as compared to 2009. This decrease is attributable to a $2.1 million decrease in the allowance for funds used during construction, which is primarily due to the completion of the Empire Connector project in December 2008. In addition, a death benefit gain on corporate- owned life insurance policies of $2.3 million recognized during the first quarter of 2009 did not recur in 2010. Other income was $1.0 million higher in 2009 as compared to 2008. This increase was primarily due to a death benefit gain on corporate-owned life insurance policies of $2.3 million recognized during the first quarter of 2009. In addition, there was a larger year-over-year increase in the value of corporate-owned life insurance policies ($1.8 million). This increase is partially offset by a $2.2 million decrease in the allowance for funds used during construction, which is primarily due to the completion of the Empire Connector project in December 2008. In addition, Horizon Power recognized a $0.9 million pre-tax gain on the sale of a turbine during 2008 that did not recur in 2009. 45 INTEREST CHARGES Although most of the variances in Interest Charges are discussed in the earnings discussion by segment above, the following is a summary on a consolidated basis: Interest on long-term debt increased $7.8 million in 2010 as compared to 2009. The increase in 2010 was primarily the result of a higher average amount of long-term debt outstanding combined with higher average interest rates. In April 2009, the Company issued $250 million of 8.75% senior, unsecured notes due in May 2019. This increase was partially offset by the repayment of $100 million of 6% medium-term notes that matured in March 2009. In addition, during fiscal 2009, the Exploration and Production segment significantly increased its capital expenditures related to unproved properties in the Marcellus Shale area of the Appalachian region. As a result, the Company capitalized interest costs associated with capital expenditures, which decreased interest expense by $1.1 million. Interest on long-term debt increased $9.3 million in 2009 as compared to 2008. The increase in 2009 was primarily the result of a higher average amount of long-term debt outstanding combined with higher average interest rates due to the April 2009 debt issuance discussed above. This increase was partially offset by the repayment of $100 million of 6% medium-term notes that matured in March 2009. Other interest charges decreased $0.6 million in 2010 compared to 2009. The decrease is mainly attributable to a $1.4 million decrease in interest expense on regulatory deferrals (primarily deferred gas costs) in the Utility segment, which was partially offset by a $0.9 million decrease in the allowance for borrowed funds used during construction resulting from the completion of the Empire Connector in December 2009. Other interest charges increased $4.1 million in 2009 compared to 2008. The increase in 2009 was primarily caused by a $2.3 million increase in interest expense on regulatory deferrals (primarily deferred gas costs) in the Utility segment’s New York jurisdiction combined with a $0.7 million decrease in the allowance for borrowed funds used during construction related to the Empire Connector project. In addition, there was an increase due to an audit adjustment on a state tax return from 2008 ($0.4 million). 46 CAPITAL RESOURCES AND LIQUIDITY The primary sources and uses of cash during the last three years are summarized in the following condensed statement of cash flows: Sources (Uses) of Cash Provided by Operating Activities . . . . . . . . . . . . . . . . . . . . . . . . . $ 459.7 (455.8) Capital Expenditures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Non-cash items include depreciation, depletion and amortization, impairment of oil and gas producing properties, impairment of investment in partnership, deferred income taxes, income or loss from unconsolidated subsidiaries net of cash distributions and gain on sale of discontinued operations. Cash provided by operating activities in the Utility and Pipeline and Storage segments may vary substantially from year to year because of the impact of rate cases. In the Utility segment, supplier refunds, over- or under-recovered purchased gas costs and weather may also significantly impact cash flow. The impact of weather on cash flow is tempered in the Utility segment’s New York rate jurisdiction by its WNC and in the Pipeline and Storage segment by the straight fixed-variable rate design used by Supply Corporation and Empire. Cash provided by operating activities in the Exploration and Production segment may vary from period to period as a result of changes in the commodity prices of natural gas and crude oil. The Company uses various derivative financial instruments, including price swap agreements and futures contracts in an attempt to manage this energy commodity price risk. Net cash provided by operating activities totaled $459.7 million in 2010, a decrease of $152.1 million compared with the $611.8 million provided by operating activities in 2009. The decrease is primarily due to the timing of gas cost recovery in the Utility segment. As gas prices decreased significantly during 2009, the Company’s Utility segment experienced an over-recovery of gas costs that was reflected in Amounts Payable to Customers on the Company’s Consolidated Balance Sheet. Since September 30, 2009, the Company has been 47 refunding that over-recovery to its customers. From a consolidated perspective, higher interest payments on long-term debt also contributed to the decrease in cash provided by operating activities. Net cash provided by operating activities totaled $611.8 million in 2009, an increase of $129.0 million compared with the $482.8 million provided by operating activities in 2008. The increase is primarily due to the timing of gas cost recovery in the Utility segment. As gas prices decreased significantly during 2009, the Company’s Utility segment experienced an over-recovery of gas costs that is reflected in Amounts Payable to Customers on the Company’s Consolidated Balance Sheet at September 30, 2009. At September 30, 2008, the Company’s Utility segment was in an under-recovery position. INVESTING CASH FLOW Expenditures for Long-Lived Assets The Company’s expenditures from continuing operations for long-lived assets totaled $501.4 million, $341.4 million and $414.4 million in 2010, 2009 and 2008, respectively.

This amount has been excluded from the Consolidated Statement of Cash Flows at September 30, 2010 since it represents a non-cash investing activity at that date. (2) Capital expenditures for the Exploration and Production segment for 2010 exclude $9.1 million of accrued capital expenditures, the majority of which was in the Appalachian region. Capital expenditures for All Other for 2010 exclude $0.7 million of accrued capital expenditures related to the construction of the Midstream Covington Gathering System. Both of these amounts were accrued at September 30, 2009 and paid during the year ended September 30, 2010. These amounts were included in the 2009 capital expenditures shown in the table above, but were excluded from the Consolidated Statement of Cash Flows at September 30, 2009 since they represented non-cash investing activities at that date. These amounts have been included in the Consolidated Statement of Cash Flows at September 30, 2010. (3) Amount for 2009 excludes $16.8 million of accrued capital expenditures related to the Empire Connector project accrued at September 30, 2008 and paid during the year ended September 30, 2009. This amount was included in 2008 capital expenditures shown in the table above, but was excluded from the Consolidated Statement of Cash Flows at September 30, 2008 since it represented a non-cash investing activity at that date. The amount was included in the Consolidated Statement of Cash Flows at September 30, 2009. (4) Investment amount is net of $4.3 million of cash acquired. 48 (5) Represents $0.3 million of capital expenditures in the Pipeline and Storage segment for the purchase of pipeline facilities from the Appalachian region of the Exploration and Production segment during the quarter ended December 31, 2008. (6) Represents $2.4 million of capital expenditures included in the Appalachian region of the Exploration and Production segment for the purchase of storage facilities, buildings, and base gas from Supply Corporation during the quarter ended March 31, 2008. (7) Excludes expenditures for long-lived assets associated with discontinued operations as follows: $0.1 million for 2010, $0.2 million for 2009, and $0.1 million for 2008. Utility The majority of the Utility capital expenditures for 2010, 2009 and 2008 were made for replacement of mains and main extensions, as well as for the replacement of service lines. Pipeline and Storage The majority of the Pipeline and Storage segment’s capital expenditures for 2010 were made for additions, improvements, and replacements to this segment’s transmission and gas storage systems. The Pipeline and Storage capital expenditure amounts for 2010 also include $6.0 million spent on the Lamont Project, discussed below. The majority of the Pipeline and Storage segment’s capital expenditures for 2009 and 2008 were related to the Empire Connector project, which was placed into service on December 10, 2008, as well as for additions, improvements, and replacements to this segment’s transmission and gas storage systems. The Empire Connector project was completed for a cost of approximately $192 million. The Company capitalized Empire Connector project costs of $27.3 million and $149.2 million for the years ended September 30, 2009 and 2008, respectively. Exploration and Production In 2010, the Exploration and Production segment capital expenditures were primarily well drilling and completion expenditures and included approximately $14.9 million for the Gulf Coast region, the majority of which was for the off-shore program in the shallow waters of the Gulf of Mexico, $27.6 million for the West Coast region and $355.7 million for the Appalachian region (including $332.4 million in the Marcellus Shale area). These amounts included approximately $28.9 million spent to develop proved undeveloped reserves. The capital expenditures in the Appalachian region include the Company’s acquisition of two tracts of leasehold acreage for approximately $71.8 million. The Company acquired these tracts in order to expand its Marcellus Shale acreage holdings. These tracts, consisting of approximately 18,000 net acres in Tioga and Potter Counties in Pennsylvania, are geographically similar to the Company’s existing Marcellus Shale acreage in the area, and will help the Company continue its developmental drilling program. The transaction closed on March 12, 2010. The Company funded this transaction with cash from operations. In 2009, the Exploration and Production segment’s capital expenditures were primarily well drilling and completion expenditures and included approximately $18.3 million for the Gulf Coast region, substantially all of which was for the off-shore program in the shallow waters of the Gulf of Mexico, $31.4 million for the West Coast region and $138.6 million for the Appalachian region. These amounts included approximately $24.2 million spent to develop proved undeveloped reserves. In July 2009, the Company’s wholly-owned subsidiary in the Exploration and Production segment, Seneca, purchased Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million in cash (including cash acquired of $4.3 million). The cash acquired at acquisition includes $2.0 million held in escrow at September 30, 2010 and 2009. Seneca placed this amount in escrow as part of the purchase price. Currently, the Company and Ivanhoe Energy are negotiating a final resolution to the issue of whether Ivanhoe Energy is entitled to some or all of the amount held in escrow. This purchase complements the segment’s existing oil producing assets in the Midway Sunset Field in California. This acquisition was funded with cash on hand. In 2008, the Exploration and Production segment’s capital expenditures were primarily well drilling and completion expenditures and included approximately $63.6 million for the Gulf Coast region, substantially all 49 of which was for the off-shore program in the shallow waters of the Gulf of Mexico, $62.8 million for the West Coast region and $65.8 million for the Appalachian region. These amounts included approximately $25.4 million spent to develop proved undeveloped reserves. The Appalachian region capital expenditures include $2.4 million for the purchase of storage facilities, buildings, and base gas from Supply Corporation, as shown in the table above. All Other and Corporate In 2010 and 2009, the majority of the All Other category’s capital expenditures for long-lived assets were for the construction of Midstream Corporation’s Covington Gathering System, as discussed below. NFG Midstream Covington, LLC, a wholly owned subsidiary of Midstream Corporation, constructed a gathering system in Tioga County, Pennsylvania. The project, called the Covington Gathering System, was constructed in two phases. The first phase was completed and placed in service in November 2009. The second phase was placed in service in May 2010. The system consists of approximately 10 miles of gathering system at a cost of $14.5 million. During the years ended September 30, 2010 and 2009, Midstream Corporation spent $6.4 million and $8.1 million, respectively, related to this project. On September 17, 2010, the Company completed the sale of its sawmill in Marienville, Pennsylvania, including approximately 23 million board feet of logs and timber consisting of yard inventory along with unexpired timber cutting contracts and certain land and timber holdings designed to provide the purchaser with a supply of logs for the mill. Despite this sale, the Company has retained substantially all of its land and timber holdings, along with mineral rights on land to be sold. The Company will maintain a forestry operation; however, as part of this change in focus, the Company will no longer be processing lumber products. The Company received proceeds of approximately $15.8 million from the sale. In addition, the purchaser assumed approximately $7.4 million in payment obligations under the Company’s timber cutting contracts with various timber suppliers. In addition to the 23 million board feet mentioned above, the Company expects to sell an additional 17 million board feet of logs to the purchaser over a five-year period, during which time the Company anticipates receiving up to an additional $10 million in proceeds. There was not a material impact to earnings from this sale. In 2008, the majority of the All Other and Corporate category’s expenditures for long-lived assets were for construction of a lumber sorter for Highland’s sawmill operations that was placed into service in October 2007, as well as for purchases of equipment for Highland’s sawmill and kiln operations. Additionally, Horizon Power sold a gas-powered turbine in March 2008 that it had planned to use in the development of a co-generation plant. Horizon Power received proceeds of $5.3 million and recorded a pre-tax gain of $0.9 million associated with the sale. Estimated Capital Expenditures The Company’s estimated capital expenditures for the next three years are: Utility. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 58.0 130.0 Pipeline and Storage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 455.0 Exploration and Production(1)(2) . . . . . . . . . . . . . . . . . . . . . . . . . 30.0 All Other . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2011 2013 Year Ended September 30 2012 (Millions) $ 58.0 124.0 596.0 11.0 $ 58.0 341.0 606.0 10.0 $673.0 $789.0 $1,015.0 (1) Includes estimated expenditures for the years ended September 30, 2011, 2012 and 2013 of approximately $140 million, $74 million and $29 million, respectively, to develop proved undeveloped reserves. The Company is committed to developing its proved undeveloped reserves within five years of being recorded as proved undeveloped reserves as required by the SEC’s final rule on Modernization of Oil and Gas Reporting. 50 (2) Exploration and Production segment estimated capital expenditures do not take into account possible joint-venture opportunities involving this segment’s Marcellus Shale acreage. The amounts could change if a joint-venture is formed. Utility Estimated capital expenditures for the Utility segment in 2011 will be concentrated in the areas of main and service line improvements and replacements and, to a lesser extent, the purchase of new equipment. Pipeline and Storage Estimated capital expenditures for the Pipeline and Storage segment in 2011 will be concentrated on the replacement of transmission and storage lines, the reconditioning of storage wells, improvements of compressor stations and construction of new pipeline and compressor stations to support expansion projects. In light of the growing demand for pipeline capacity to move natural gas from new wells being drilled in Appalachia — specifically in the Marcellus Shale producing area — Supply Corporation and Empire are actively pursuing several expansion projects and paying for preliminary survey and investigation costs, which are initially recorded as Deferred Charges on the Consolidated Balance Sheet. An offsetting reserve is established as those preliminary survey and investigation costs are incurred, which reduces the Deferred Charges balance and increases Operation and Maintenance Expense on the Consolidated Statement of Income. The Company reviews all projects on a quarterly basis, and if it is determined that it is highly probable that the project will be built, the reserve is reversed. This reversal reduces Operation and Maintenance Expense and reestablishes the original balance in Deferred Charges. After the reversal of the reserve, amounts remain in Deferred Charges until construction begins, at which point the balance is transferred from Deferred Charges to Construction Work in Progress, a component of Property, Plant and Equipment on the Consolidated Balance Sheet. As of September 30, 2010, the total amount reserved for the Pipeline and Storage segment’s preliminary survey and investigation costs was $5.1 million. Supply Corporation is moving forward with several projects designed to move anticipated Marcellus production gas to other interstate pipelines and to markets beyond Supply Corporation’s pipeline system. Supply Corporation has signed a precedent agreement to provide 320,000 Dth/day of firm transportation capacity in conjunction with its “Northern Access” expansion project. Upon satisfaction of the conditions in the precedent agreement, Statoil Natural Gas LLC will enter into a 20-year firm transportation agreement for 320,000 Dth/day. This capacity will provide the subscribing shipper with a firm transportation path from the Tennessee Gas Pipeline (“TGP”) 300 Line at Ellisburg into the TransCanada Pipeline at Niagara. This path is attractive because it provides a route for Marcellus shale gas, principally along the TGP 300 Line in northern Pennsylvania, to be transported from the Marcellus supply basin to northern markets. Service is expected to begin in late 2012, and Supply Corporation has begun working on an application for FERC authorization of the project, which it expects to file in the second quarter of fiscal year 2011. The project facilities involve additional compression at Supply Corporation’s existing Ellisburg Station and at a new station in East Aurora, New York, along with other system enhancements including the jointly owned Niagara Spur Loop Line. The preliminary cost estimate for the Northern Access expansion is $60 million. These expenditures are included as Pipeline and Storage segment estimated capital expenditures in the table above. As of September 30, 2010, less than $0.1 million has been spent to study the Northern Access expansion project, which has been included in preliminary survey and investigation charges and has been fully reserved for at September 30, 2010. One strategic horsepower expansion project involves new compression along Supply Corporation’s Line N (“Line N Expansion Project”), increasing that line’s capacity by 160,000 Dth/day into Texas Eastern’s Holbrook Station (“TETCO Holbrook”) in southwestern Pennsylvania. A precedent agreement for 150,000 Dth/day of firm transportation has been executed and negotiations are underway for the remaining capacity. The project will allow Marcellus production located in the vicinity of Line N to flow south into Texas Eastern and access markets off Texas Eastern’s system, with a projected in-service date of September 2011. On October 20, 2009, the FERC granted Supply Corporation’s request for a pre-filing environmental review of the Line N Expansion Project, and on June 11, 2010, Supply Corporation filed an NGA Section 7(c) application to the FERC for 51 approval of the project. The preliminary cost estimate for the Line N Expansion Project is $23 million, all of which is expected to be spent in fiscal 2011 and 2012 except for approximately $2.0 million already spent through September 30, 2010. These expenditures are included as Pipeline and Storage segment estimated capital expenditures in the table above. The Company has determined that it is highly probable that this project will be built. Accordingly, all previous reserves established in connection with this project have been reversed, and the $2.0 million has been reestablished as a Deferred Charge on the Consolidated Balance Sheet. Supply Corporation has also executed a precedent agreement for 150,000 Dth/day of additional capacity on Line N to TETCO Holbrook to be ready for service beginning November 2012 (“Line N Phase II Expansion Project”). The Line N Phase II Expansion Project will provide approximately 195,000 Dth/day of incremental firm transportation capacity. Marketing efforts are underway for the remaining 45,000 Dth/day of capacity. The preliminary cost estimate for the Line N Phase II Expansion Project is approximately $40 million. These expenditures are included as Pipeline and Storage segment estimated capital expenditures in the table above. As of September 30, 2010, less than $0.1 million has been spent to study the Line N Phase II Expansion Project, which has been included in preliminary survey and investigation charges and has been fully reserved for at September 30, 2010. Another strategic horsepower expansion project, involving the addition of compression at Supply Corporation’s existing interconnect with TGP at Lamont, Pennsylvania, has been in service since June 15, 2010 (“Lamont Project”). A second Lamont Project phase is planned (“Lamont Phase II Project”). With the construction of additional horsepower, 50,000 Dth/day of incremental firm capacity will be available starting July 1, 2011 ramping up to full service by October 1, 2011. Supply Corporation has two signed precedent agreements for the full capacity of this project. The preliminary cost estimate for the Lamont Phase II Project is approximately $7 million. These expenditures are included as Pipeline and Storage segment estimated capital expenditures in the table above. As of September 30, 2010, less than $0.1 million has been spent to study the Lamont Phase II project, which has been included in preliminary survey and investigation charges and has been fully reserved for at September 30, 2010. In addition, Supply Corporation continues to actively pursue its largest planned expansion, the West-to-East (“W2E”) pipeline project, which is designed to transport Rockies and/or locally produced natural gas supplies to the Ellisburg/Leidy/Corning area. Supply Corporation anticipates that the development of the W2E project will occur in phases. As currently envisioned, the first two phases of W2E, referred to as the “W2E Overbeck to Leidy” project, are designed to transport at least 425,000 Dth/ day, and involves construction of a new 82-mile pipeline through Elk, Cameron, Clinton, Clearfield and Jefferson Counties to the Leidy Hub, from Marcellus and other producing areas along over 300 miles of Supply Corporation’s existing pipeline system. The W2E Overbeck to Leidy project also includes a total of approximately 25,000 horsepower of compression at two separate stations. The project may be built in phases depending on the development of Marcellus production along the corridor, with the first facilities expected to go in service in 2013. Following an Open Season that concluded on October 8, 2009, Supply Corporation executed precedent agreements to provide 125,000 Dth/day of firm transportation on the W2E Overbeck to Leidy project. Supply Corporation is pursuing post-Open Season capacity requests for the remaining capacity. On March 31, 2010, the FERC granted Supply Corporation’s request for a pre-filing environmental review of the W2E Overbeck to Leidy project, and Supply Corporation is in the process of preparing an NGA Section 7(c) application. The capital cost of the W2E Overbeck to Leidy project is estimated to be $260 million, approximately $191 million of which is expected to be spent during the period of fiscal 2011 through 2013. These expenditures are included as Pipeline and Storage segment estimated capital expenditures in the table above. As of September 30, 2010, approximately $3.8 million has been spent to study the W2E Overbeck to Leidy project, which has been included in preliminary survey and investigation charges and has been fully reserved for at September 30, 2010. Supply Corporation expects that its previously announced Appalachian Lateral project will complement the W2E Overbeck to Leidy project due to its strategic upstream location. The Appalachian Lateral pipeline, which would be routed through several counties in central Pennsylvania where producers are actively drilling 52 and seeking market access for their newly discovered reserves, will be able to collect and transport locally produced Marcellus shale gas into the W2E Overbeck to Leidy facilities. Supply Corporation expects to continue marketing efforts for the Appalachian Lateral and all other remaining sections of W2E. The timeline and projected costs associated with W2E sections other than W2E Overbeck to Leidy, including the Appalachian Lateral project, will depend on market development, and as of September 30, 2010, no preliminary survey and investigation charges had been spent on those projects and no capital expenditures are included as estimated capital expenditures in the table above. Supply Corporation has also developed plans for new storage capacity by expansion of two of its existing storage facilities. The expansion of the East Branch and Galbraith fields will provide 7.9 MMDth of incremental storage capacity and approximately 88 MDth per day of additional withdrawal deliverability. This storage expansion project, if pursued, would require an NGA Section 7(c) application, which Supply Corporation has not yet filed. The preliminary cost estimate for this storage expansion project is $64 million. These expenditures are not included as Pipeline and Storage segment estimated capital expenditures in the table above. As of September 30, 2010, approximately $1.0 million has been spent to study this storage expansion project, which has been included in preliminary survey and investigation charges and has been fully reserved for at September 30, 2010. The specific timeline associated with the storage expansion will depend on market development, which at this time, due to economic conditions, does not warrant additional project development. Empire has executed precedent agreements for all 350,000 Dth/day of incremental firm transportation capacity in its “Tioga County Extension Project.” This project will transport Marcellus production from new interconnections at the southern terminus of a 16-mile extension of its recently completed Empire Connector line, in Tioga County, Pennsylvania. Empire’s preliminary cost estimate for the Tioga County Extension Project is approximately $46 million, all of which is expected to be spent in fiscal 2011 and 2012 except for approximately $2.0 million already spent through September 30, 2010. These expenditures are included as Pipeline and Storage segment estimated capital expenditures in the table above. This project will enable shippers to deliver their natural gas at existing Empire interconnections with Millennium Pipeline at Corning, New York, with the TransCanada Pipeline at the Niagara River at Chippawa, and with utility and power generation markets along its path, as well as to a planned new interconnection with TGP’s 200 Line (Zone 5) in Ontario County, New York. On January 28, 2010, the FERC granted Empire’s request for a pre-filing environmental review of the Tioga County Extension Project, and on August 26, 2010, Empire filed an NGA Section 7(c) application to the FERC for approval of the project. Empire anticipates that these facilities will be placed in service on September 1, 2011. The Company has determined that it is highly probable that this project will be built. Accordingly, all previous reserves have been reversed and the $2.0 million has been reestablished as a Deferred Charge on the Consolidated Balance Sheet. Empire is evaluating a second phase expansion of the Tioga County Extension Project that could extend the Empire system further into the Marcellus production area in Pennsylvania, and/or increase the capacity by up to 260,000 Dth/day by late 2013. The cost of this second phase could be as much as $135 million, most of which would be spent in fiscal 2013 and is included as Pipeline and Storage segment estimated capital expenditures in the table above. The Company anticipates financing the Line N Expansion Projects, the Lamont Projects, the Northern Access expansion project, the W2E Overbeck to Leidy project, the Appalachian Lateral project, and the Tioga County Extension Projects, all of which are discussed above, with a combination of cash from operations, short- term debt, and long-term debt. The Company had $395.2 million in Cash and Temporary Cash Investments at September 30, 2010, as shown on the Company’s Consolidated Balance Sheet. The Company expects to use cash from operations as the first means of financing these projects, with short-term debt providing temporary financing when needed. The Company may issue some long-term debt in conjunction with these projects in the later part of fiscal 2011 or in fiscal 2012. Exploration and Production Estimated capital expenditures in 2011 for the Exploration and Production segment include approximately $11.0 million for the Gulf Coast region, substantially all of which is for the off-shore program in the shallow waters of the Gulf of Mexico, $39.0 million for the West Coast region and $405.0 million for the Appalachian region. The Company anticipates drilling 100 to 130 gross wells in the Marcellus Shale during 2011. 53 Estimated capital expenditures in 2012 for the Exploration and Production segment include approximately $20.0 million for the Gulf Coast region, substantially all of which is for the off-shore program in the shallow waters of the Gulf of Mexico, $43.0 million for the West Coast region and $533.0 million for the Appalachian region. The Company anticipates drilling 130 to 160 gross wells in the Marcellus Shale during 2012. Estimated capital expenditures in 2013 for the Exploration and Production segment include approximately $47.0 million for the West Coast region and $559.0 million for the Appalachian region. The Company does not expect to incur any significant capital expenditures in the Gulf Coast region during 2013. The Company anticipates drilling 140 to 170 gross wells in the Marcellus Shale during 2013. It is anticipated that these future capital expenditures will be funded with a combination of cash from operations, short-term debt, and long-term debt. Natural gas and crude oil prices combined with production from existing wells will be a significant factor in determining how much of the capital expenditures are funded from cash from operations. The Company expects to use cash from operations as the first means of financing these expenditures, with short-term debt providing temporary financing when needed. The Company may issue some long-term debt in conjunction with these expenditures in the later part of fiscal 2011 or in fiscal 2012. All Other and Corporate Estimated capital expenditures in 2011 for the All Other and Corporate category will primarily be for construction of anticipated gathering systems, including the construction of Midstream Corporation’s Trout Run Gathering System, as discussed below. NFG Midstream Trout Run, LLC, a wholly owned subsidiary of Midstream Corporation, is planning a gathering system in Lycoming County, Pennsylvania. The project, called the Trout Run Gathering System, is anticipated to be placed in service in the fall of 2011. The system will consist of approximately 15.5 miles of gathering system at a cost of $27 million. These expenditures are included as All Other category capital expenditures in the table above. As of September 30, 2010, the Company has spent approximately $0.1 million in costs related to this project. The Company anticipates funding the Midstream Corporation project with cash from operations and/or short-term borrowings. Given the Company’s cash position at September 30, 2010, the Company expects to use cash from operations as the first means of financing these projects. The Company continuously evaluates capital expenditures and investments in corporations, partnerships, and other business entities. The amounts are subject to modification for opportunities such as the acquisition of attractive oil and gas properties, natural gas storage facilities and the expansion of natural gas transmission line capacities. While the majority of capital expenditures in the Utility segment are necessitated by the continued need for replacement and upgrading of mains and service lines, the magnitude of future capital expenditures or other investments in the Company’s other business segments depends, to a large degree, upon market conditions. FINANCING CASH FLOW The Company did not have any outstanding short-term notes payable to banks or commercial paper at September 30, 2010 or during the fiscal year ended September 30, 2010. However, the Company continues to consider short-term debt (consisting of short-term notes payable to banks and commercial paper) an important source of cash for temporarily financing capital expenditures and investments in corporations and/or partnerships, gas-in-storage inventory, unrecovered purchased gas costs, margin calls on derivative financial instruments, exploration and development expenditures, repurchases of stock, and other working capital needs. Fluctuations in these items can have a significant impact on the amount and timing of short-term debt. As for bank loans, the Company maintains a number of individual uncommitted or discretionary lines of credit with certain financial institutions for general corporate purposes. Borrowings under these lines of credit are made at competitive market rates. These credit lines, which aggregate to $405.0 million, are revocable at the option of the financial institutions and are reviewed on an annual basis. The Company anticipates that these lines of credit will continue to be renewed, or substantially replaced by similar lines. The total amount available to be issued 54 under the Company’s commercial paper program is $300.0 million. The commercial paper program is backed by facility totaling $300.0 million, which commitment extends through a syndicated committed credit September 30, 2013. Under the Company’s committed credit facility, the Company has agreed that its debt to capitalization ratio will not exceed .65 at the last day of any fiscal quarter through September 30, 2013. At September 30, 2010, the Company’s debt to capitalization ratio (as calculated under the facility) was .42. The constraints specified in the committed credit facility would permit an additional $1.99 billion in short-term and/or long-term debt to be outstanding (further limited by the indenture covenants discussed below) before the Company’s debt to capitalization ratio would exceed .65. If a downgrade in any of the Company’s credit ratings were to occur, access to the commercial paper markets might not be possible. However, the Company expects that it could borrow under its committed credit facility, uncommitted bank lines of credit or rely upon other liquidity sources, including cash provided by operations. In addition, the Company’s cost of capital is directly affected by its credit ratings. At September 30, 2010, the Company’s long-term debt ratings were: BBB (S&P), Baa1 (Moody’s Investor Service), and BBB+ (Fitch Ratings Service). In March 2010, Fitch Ratings Service decreased the Company’s long-term debt rating from A- to BBB+. The Company does not believe that this ratings action will impact its access to the commercial paper markets. At September 30, 2010, the Company’s commercial paper ratings were: A-2 (S&P), P-2 (Moody’s Investor Service), and F2 (Fitch Ratings Service). A credit rating is not a recommendation to buy, sell or hold securities. Each credit rating agency has its own methodology for assigning ratings, and, accordingly, each rating should be considered in the context of the applicable methodology, independently of all other ratings. The rating agencies provide ratings at the request of the Company and charge the Company fees for their services. Under the Company’s existing indenture covenants, at September 30, 2010, the Company would have been permitted to issue up to a maximum of $1.3 billion in additional long-term unsecured indebtedness at then current market interest rates in addition to being able to issue new indebtedness to replace maturing debt. The Company’s present liquidity position is believed to be adequate to satisfy known demands. However, if the Company were to experience a significant loss in the future (for example, as a result of an impairment of oil and gas properties), it is possible, depending on factors including the magnitude of the loss, that these indenture covenants would restrict the Company’s ability to issue additional long-term unsecured indebtedness for a period of up to nine calendar months, beginning with the fourth calendar month following the loss. This would not at any time preclude the Company from issuing new indebtedness to replace maturing debt. The Company’s 1974 indenture pursuant to which $99.0 million (or 7.9%) of the Company’s long-term debt (as of September 30, 2010) was issued, contains a cross-default provision whereby the failure by the Company to perform certain obligations under other borrowing arrangements could trigger an obligation to repay the debt outstanding under the indenture. In particular, a repayment obligation could be triggered if the Company fails (i) to pay any scheduled principal or interest on any debt under any other indenture or agreement or (ii) to perform any other term in any other such indenture or agreement, and the effect of the failure causes, or would permit the holders of the debt to cause, the debt under such indenture or agreement to become due prior to its stated maturity, unless cured or waived. The Company’s $300.0 million committed credit facility also contains a cross-default provision whereby the failure by the Company or its significant subsidiaries to make payments under other borrowing arrangements, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the committed credit facility. In particular, a repayment obligation could be triggered if (i) the Company or any of its significant subsidiaries fails to make a payment when due of any principal or interest on any other indebtedness aggregating $40.0 million or more or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $40.0 million or more to cause, such indebtedness to become due prior to its stated maturity. As of September 30, 2010, the Company had no debt outstanding under the committed credit facility. The Company’s embedded cost of long-term debt was 6.95% at both September 30, 2010 and September 30, 2009. If the Company were to issue long-term debt today, its borrowing costs might be expected to be in the 55 range of 5.0% to 6.5% depending on the maturity date. Refer to “Interest Rate Risk” in this Item for a more detailed breakdown of the Company’s embedded cost of long-term debt. Current Portion of Long-Term Debt at September 30, 2010 consists of $200 million of 7.50% medium-term notes that mature in November 2010. Currently, the Company expects to refund these medium-term notes in November 2010 with cash on hand and/or short-term borrowings. In April 2009, the Company issued $250.0 million of 8.75% notes due in May 2019. After deducting underwriting discounts and commissions, the net proceeds to the Company amounted to $247.8 million. These notes were registered under the Securities Act of 1933. The holders of the notes may require the Company to repurchase their notes at a price equal to 101% of the principal amount in the event of both a change in control and a ratings downgrade to a rating below investment grade. The proceeds of this debt issuance were used for general corporate purposes, including to replenish cash that was used to pay the $100 million due at the maturity of the Company’s 6.0% medium-term notes on March 1, 2009. On December 8, 2005, the Company’s Board of Directors authorized the Company to implement a share repurchase program, whereby the Company could repurchase outstanding shares of common stock, up to an aggregate amount of eight million shares in the open market or through privately negotiated transactions. The Company completed the repurchase of the eight million shares during 2008 for a total program cost of $324.2 million (of which 4,165,122 shares were repurchased during the year ended September 30, 2008 for $191.0 million). In September 2008, the Company’s Board of Directors authorized the repurchase of an additional eight million shares of the Company’s common stock. Under this new authorization, the Company repurchased 1,028,981 shares for $46.0 million through September 17, 2008. The Company, however, stopped repurchasing shares after September 17, 2008 in light of the unsettled nature of the credit markets. Since that time, the Company has increased its emphasis on Marcellus Shale development and pipeline expansion. As such, the Company does not anticipate repurchasing any shares in the near future. The share repurchases mentioned above were funded with cash provided by operating activities and/or through the use of the Company’s lines of credit. The Company may issue debt or equity securities in a public offering or a private placement from time to time. The amounts and timing of the issuance and sale of debt or equity securities will depend on market conditions, indenture requirements, regulatory authorizations and the capital requirements of the Company. OFF-BALANCE SHEET ARRANGEMENTS The Company has entered into certain off-balance sheet financing arrangements. These financing arrangements are primarily operating leases. The Company’s consolidated subsidiaries have operating leases, the majority of which are with the Utility and the Pipeline and Storage segments, having a remaining lease commitment of approximately $27.4 million. These leases have been entered into for the use of buildings, vehicles, construction tools, meters and other items and are accounted for as operating leases. The following table summarizes the Company’s expected future contractual cash obligations as of September 30, 2010, and the twelve-month periods over which they occur: CONTRACTUAL OBLIGATIONS Payments by Expected Maturity Dates 2011 2012 2013 2014 (Millions) 2015 Thereafter Total Long-Term Debt, including interest expense(1). . . . . . . . . . . . . . . . . . . . . . . . $274.0 5.1 Operating Lease Obligations . . . . . . . . . . . . . $ Purchase Obligations: $213.2 4.6 $ $304.2 3.5 $ $48.7 $ 3.2 $48.7 $ 2.8 $839.9 8.2 $ $1,728.7 27.4 $ Gas Purchase Contracts(2) . . . . . . . . . . . . $337.8 Transportation and Storage Contracts . . . . . $ 42.3 Other . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 25.1 $ 47.7 $ 38.6 5.1 $ $ 13.2 $ 38.4 4.0 $ $ 0.4 $34.3 $ 3.9 $ — $19.8 $ 3.7 $ — $ 14.5 $ 11.3 $ 399.1 $ 187.9 53.1 $ 56 (1) Refer to Note E — Capitalization and Short-Term Borrowings, as well as the table under Interest Rate Risk in the Market Risk Sensitive Instruments section below, for the amounts excluding interest expense. (2) Gas prices are variable based on the NYMEX prices adjusted for basis. The Company has other long-term obligations recorded on its Consolidated Balance Sheets that are not reflected in the table above. Such long-term obligations include pension and other post-retirement liabilities, asset retirement obligations, deferred income tax liabilities, various regulatory liabilities, derivative financial instrument liabilities and other deferred credits (the majority of which consist of liabilities for non-qualified benefit plans, deferred compensation liabilities, environmental liabilities, workers compensation liabilities and liabilities for income tax uncertainties). The Company has made certain other guarantees on behalf of its subsidiaries. The guarantees relate primarily to: (i) obligations under derivative financial instruments, which are included on the Consolidated Balance Sheets in accordance with the authoritative guidance (see Item 7, MD&A under the heading “Critical Accounting Estimates — Accounting for Derivative Financial Instruments”); (ii) NFR obligations to purchase gas or to purchase gas transportation/storage services where the amounts due on those obligations each month are included on the Consolidated Balance Sheets as a current liability; and (iii) other obligations which are reflected on the Consolidated Balance Sheets. The Company believes that the likelihood it would be required to make payments under the guarantees is remote, and therefore has not included them in the table above. OTHER MATTERS In addition to the environmental and other matters discussed in this Item 7 and in Item 8 at Note I — Commitments and Contingencies, the Company is involved in other litigation and regulatory matters arising in the normal course of business. These other matters may include, for example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations or other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas cost issues, among other things. While these normal-course matters could have a material effect on earnings and cash flows in the period in which they are resolved, they are not expected to change materially the Company’s present liquidity position, nor are they expected to have a material adverse effect on the financial condition of the Company. The Company has a tax-qualified, noncontributory defined-benefit retirement plan (Retirement Plan) that covers a majority of the Company’s employees. The Company has been making contributions to the Retirement Plan over the last several years and anticipates that it will continue making contributions to the Retirement Plan. During 2010, the Company contributed $22.2 million to the Retirement Plan. The Company anticipates that the annual contribution to the Retirement Plan in 2011 will be in the range of $40.0 million to $45.0 million. Changes in the discount rate, other actuarial assumptions, and asset performance could ultimately cause the Company to fund larger amounts to the Retirement Plan in 2011 in order to be in compliance with the Pension Protection Act of 2006. The Company expects that all subsidiaries having employees covered by the Retirement Plan will make contributions to the Retirement Plan. The funding of such contributions will come from amounts collected in rates in the Utility and Pipeline and Storage segments or through short-term borrowings or through cash from operations. The Company provides health care and life insurance benefits (other post-retirement benefits) for a majority of its retired employees. The Company has established VEBA trusts and 401(h) accounts for its other post-retirement benefits. The Company has been making contributions to its VEBA trusts and 401(h) accounts over the last several years and anticipates that it will continue making contributions to the VEBA trusts and 401(h) accounts. During 2010, the Company contributed $25.5 million to its VEBA trusts and 401(h) accounts. The Company anticipates that the annual contribution to its VEBA trusts and 401(h) accounts in 2011 will be in the range of $25.0 million to $30.0 million. The funding of such contributions will come from amounts collected in rates in the Utility and Pipeline and Storage segments. 57 As of September 30, 2010, the Company has a federal net operating loss carryover of $19.7 million, which expires in varying amounts between 2023 and 2029. Although this loss carryover is subject to certain annual limitations, no valuation allowance was recorded because of management’s determination that the amount will be fully utilized during the carryforward period. MARKET RISK SENSITIVE INSTRUMENTS Energy Commodity Price Risk The Company, in its Exploration and Production segment, Energy Marketing segment and Pipeline and Storage segment, uses various derivative financial instruments (derivatives), including price swap agreements and futures contracts, as part of the Company’s overall energy commodity price risk management strategy. Under this strategy, the Company manages a portion of the market risk associated with fluctuations in the price of natural gas and crude oil, thereby attempting to provide more stability to operating results. The Company has operating procedures in place that are administered by experienced management to monitor compliance with the Company’s risk management policies. The derivatives are not held for trading purposes. The fair value of these derivatives, as shown below, represents the amount that the Company would receive from, or pay to, the respective counterparties at September 30, 2010 to terminate the derivatives. However, the tables below and the fair value that is disclosed do not consider the physical side of the natural gas and crude oil transactions that are related to the financial instruments. On July 21, 2010, the Wall Street Reform and Consumer Protection Act (H.R. 4173) was signed into law. The law includes provisions related to the swaps and over-the-counter derivatives markets. A variety of rules must be adopted by federal agencies (including the Commodity Futures Trading Commission, SEC and the FERC) to implement the law. These rules, which will be implemented over time frames as determined in the law, could have a significant impact on the Company that was not clearly defined in the law itself. Under the law, the Company expects to be exempt from mandatory clearing and exchange trading requirements for most or all of its commodity hedges. Capital and margin requirements for these hedges are expected to be determined as regulators write more detailed rules and requirements. While the Company is currently reviewing the provisions of H.R. 4173, it will not be able to determine the impact to its financial condition until the final rules are issued. In accordance with the authoritative guidance for fair value measurements, the Company has identified certain inputs used to recognize fair value as Level 3 (unobservable inputs). The Level 3 derivative net liabilities relate to oil swap agreements used to hedge forecasted sales at a specific location (southern California). The Company’s internal model that is used to calculate fair value applies a historical basis differential (between the sales locations and NYMEX) to a forward NYMEX curve because there is not a forward curve specific to this sales location. Given the high level of historical correlation between NYMEX prices and prices at this sales location, the Company does not believe that the fair value recorded by the Company would be significantly different from what it expects to receive upon settlement. The Level 3 net liabilities amount to $16.5 million at September 30, 2010 and represent 4.6% of the Total Net Assets shown in Item 8 at Note F — Fair Value Measurements at September 30, 2010. The Company uses the crude oil swaps classified as Level 3 to hedge against the risk of declining commodity prices and not as speculative investments. Gains or losses related to these Level 3 derivative net liabilities (including any reduction for credit risk) are deferred until the hedged commodity transaction occurs in accordance with the provisions of the existing guidance for derivative instruments and hedging activities. The decrease in the net fair value of the Level 3 positions from a net asset position at October 1, 2009 to a net liability position at September 30, 2010, as shown in Item 8 at Note F, was attributable to an increase in the commodity price of crude oil relative to the swap price during that period. The Company believes that these fair values reasonably represent the amounts that the Company would realize upon settlement based on commodity prices that were present at September 30, 2010. The fair value of all of the Company’s Net Derivative Assets was reduced by $0.7 million based upon the Company’s assessment of counterparty credit risk (for the Company’s derivative assets) and the Company’s 58 credit risk (for the Company’s derivative liabilities). The Company applied default probabilities to the anticipated cash flows that it was expecting to receive and pay to its counterparties to calculate the credit reserve. The following tables disclose natural gas and crude oil price swap information by expected maturity dates for agreements in which the Company receives a fixed price in exchange for paying a variable price as quoted in various national natural gas publications or on the NYMEX. Notional amounts (quantities) are used to calculate the contractual payments to be exchanged under the contract. The weighted average variable prices represent the weighted average settlement prices by expected maturity date as of September 30, 2010. At September 30, 2010, the Company had not entered into any natural gas or crude oil price swap agreements extending beyond 2014.

The Company would have to pay its respective counterparties an aggregate of approximately $16.5 million to terminate the crude oil price swap agreements outstanding at September 30, 2010. At September 30, 2009, the Company had natural gas price swap agreements covering 38.0 Bcf at a weighted average fixed rate of $7.15 per Mcf. The Company also had crude oil price swap agreements covering 2,688,000 bbls at a weighted average fixed rate of $71.14 per bbl. The following table discloses the net contract volume purchased (sold), weighted average contract prices and weighted average settlement prices by expected maturity date for futures contracts used to manage natural gas price risk. At September 30, 2010, the Company held no futures contracts with maturity dates extending beyond 2013.

Expected Maturity Dates 2011 2012 2013 Total 59 At September 30, 2010, the Company had long (purchased) futures contracts covering 14.2 Bcf of gas extending through 2013 at a weighted average contract price of $5.47 per Mcf and a weighted average settlement price of $4.54 per Mcf. Of this amount, 14.1 Bcf is accounted for as fair value hedges and are used by the Company’s Energy Marketing segment to hedge against rising prices, a risk to which this segment is exposed to due to the fixed price gas sales commitments that it enters into with certain residential, commercial, industrial, public authority and wholesale customers. The remaining 0.1 Bcf is accounted for as cash flow hedges used to hedge against rising prices related to anticipated gas purchases for potential injections into storage. The Company would have had to pay $13.2 million to terminate these futures contracts at September 30, 2010. At September 30, 2010, the Company had short (sold) futures contracts covering 6.5 Bcf of gas extending through 2011 at a weighted average contract price of $5.52 per Mcf and a weighted average settlement price of $4.38 per Mcf. Of this amount, 5.7 Bcf is accounted for as cash flow hedges as these contracts relate to the anticipated sale of natural gas by the Energy Marketing segment. The remaining 0.8 Bcf is accounted for as fair value hedges used to hedge against falling prices, a risk to which the Energy Marketing segment is exposed to due to the fixed price gas purchase commitments that it enters into with its natural gas suppliers. The Company would have received $7.4 million to terminate these futures contracts at September 30, 2010. At September 30, 2009, the Company had long (purchased) futures contracts covering 11.6 Bcf of gas extending through 2012 at a weighted average contract price of $6.37 per Mcf and a weighted average settlement price of $6.07 per Mcf. At September 30, 2009, the Company had short (sold) futures contracts covering 6.7 Bcf of gas extending through 2011 at a weighted average contract price of $7.37 per Mcf and a weighted average settlement price of $6.07 per Mcf. Of this amount, 5.8 Bcf is accounted for as cash flow hedges as these contracts relate to the anticipated sale of natural gas by the Energy Marketing segment. The remaining 0.9 Bcf is accounted for as fair value hedges used to hedge against falling prices. The Company may be exposed to credit risk on any of the derivative financial instruments that are in a gain position. Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of the Company’s counterparties are financial institutions and energy traders. The Company has over-the-counter swap positions with eleven counterparties of which ten of the eleven counterparties are in a net gain position. On average, the Company had $6.5 million of credit exposure per counterparty in a gain position at September 30, 2010. The maximum credit exposure per counterparty at September 30, 2010 was $11.9 million. BP Energy Company (an affiliate of BP Corporation North America, Inc.) was one of the ten counterparties in a gain position. At September 30, 2010, the Company had an $11.3 million receivable with BP Energy Company. The Company considered the credit quality of BP Energy Company (as it does with all of its counterparties) in determining hedge effectiveness and believes the hedges remain effective. The Company had not received any collateral from these counterparties at September 30, 2010 since the Company’s gain position on such derivative financial instruments had not exceeded the established thresholds at which the counterparties would be required to post collateral. As of September 30, 2010, nine of the eleven counterparties to the Company’s outstanding derivative instrument contracts (specifically the over-the-counter swaps) had a common credit-risk related contingency feature. In the event the Company’s credit rating increases or falls below a certain threshold (the lower of the S&P or Moody’s Debt Rating), the available credit extended to the Company would either increase or decrease. A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt instruments). If the Company’s outstanding derivative instrument contracts were in a liability position and the Company’s credit rating declined, then additional hedging collateral deposits would be required. At September 30, 2010, the fair market value of the derivative financial instrument assets with a credit-risk related contingency feature was $42.1 million according to the Company’s internal model (discussed in Item 8 at Note F — Fair Value Measurements). At September 30, 2010, the fair market value of the derivative financial instrument liability with a credit-risk related contingency feature was $14.3 million according to the Company’s internal model (discussed in Item 8 at Note F — Fair Value Measurements). For its over-the-counter crude oil 60 swap agreements, which are in a liability position, the Company was required to post $1.0 million in hedging collateral deposits at September 30, 2010. This is discussed in Item 8 at Note A under Hedging Collateral Deposits. For its exchange traded futures contracts which are in a liability position, the Company had posted $10.1 million in hedging collateral as of September 30, 2010. As these are exchange traded futures contracts, there are no specific credit-risk related contingency features. The Company posts hedging collateral based on open positions and margin requirements it has with its counterparties. The Company’s requirement to post hedging collateral deposits is based on the fair value determined by the Company’s counterparties, which may differ from the Company’s assessment of fair value. Hedging collateral deposits may also include closed derivative positions in which the broker has not cleared the cash from the account to offset the derivative liability. The Company records liabilities related to closed derivative positions in Other Accruals and Current Liabilities on the Consolidated Balance Sheet. These liabilities are relieved when the broker clears the cash from the hedging collateral deposit account. This is discussed in Item 8 at Note A under Hedging Collateral Deposits.

RATE AND REGULATORY MATTERS Utility Operation Delivery rates for both the New York and Pennsylvania divisions are regulated by the states’ respective public utility commissions and are changed only when approved through a procedure known as a “rate case.” Currently neither division has a rate case on file. In both jurisdictions, delivery rates do not reflect the recovery of purchased gas costs. Prudently-incurred gas costs are recovered through operation of automatic adjustment clauses, and are collected through a separately-stated “supply charge” on the customer bill. New York Jurisdiction Customer delivery rates charged by Distribution Corporation’s New York division were established in a rate order issued on December 21, 2007 by the NYPSC. The rate order approved a revenue increase of $1.8 million annually, together with a surcharge that would collect up to $10.8 million to cover expenses for implementation of an efficiency and conservation incentive program. The rate order further provided for a return on equity of 9.1%. In connection with the efficiency and conservation program, the rate order approved a revenue decoupling mechanism. The revenue decoupling mechanism “decouples” revenues from throughput by enabling the Company to collect from small volume customers its allowed margin on average weather normalized usage per customer. The effect of the revenue decoupling mechanism is to render the Company financially indifferent to throughput decreases resulting from conservation. The Company surcharges or credits any difference from the average weather normalized usage per customer account. The surcharge or credit is calculated to recover total margin for the most recent twelve-month period ending December 31, and is applied to customer bills annually, beginning March 1st. 61 On April 18, 2008, Distribution Corporation filed an appeal with Supreme Court, Albany County, seeking review of the rate order. The appeal contended that portions of the rate order were invalid because they failed to meet the applicable legal standard for agency decisions. Among the issues challenged by the Company was the reasonableness of the NYPSC’s disallowance of expense items and the methodology used for calculating rate of return, which the appeal contended understated the Company’s cost of equity. Because of the issues appealed, the case was later transferred to the Appellate Division, New York State’s second-highest court. On December 31, 2009, the Appellate Division issued its Opinion and Judgment. The court upheld the NYPSC’s determination relating to the authorized rate of return but also supported the Company’s argument that the NYPSC improperly disallowed recovery of certain environmental clean-up costs. On February 1, 2010, the NYPSC filed a motion with the Court of Appeals, New York State’s highest court, seeking permission to appeal the Appellate Division’s annulment of that part of the rate order relating to disallowance of environmental clean up costs. On May 4, 2010, the NYPSC’s motion was granted, and the matter will be heard by the Court of Appeals. The Briefing schedule began on July 28, 2010 and is followed by oral argument. The Company cannot predict the outcome of the appeal proceedings at this time. Pennsylvania Jurisdiction Distribution Corporation’s current delivery charges in its Pennsylvania jurisdiction were approved by the PaPUC on November 30, 2006 as part of a settlement agreement that became effective January 1, 2007. Pipeline and Storage Supply Corporation currently does not have a rate case on file with the FERC. The rate settlement approved by the FERC on February 9, 2007 requires Supply Corporation to make a general rate filing to be effective December 1, 2011, and bars Supply Corporation from making a general rate filing before then, with some exceptions specified in the settlement. Empire’s new facilities (the Empire Connector project) were placed into service on December 10, 2008. As of that date, Empire became an interstate pipeline subject to FERC regulation, performing services under a FERC-approved tariff and at FERC-approved rates. The December 21, 2006 FERC order issuing Empire its Certificate of Public Convenience and Necessity requires Empire to file a cost and revenue study at the FERC following three years of actual operation, in conjunction with which Empire will either justify Empire’s existing recourse rates or propose alternative rates. ENVIRONMENTAL MATTERS The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment. The Company has established procedures for the ongoing evaluation of its operations to identify potential environmental exposures and comply with regulatory policies and procedures. It is the Company’s policy to accrue estimated environmental clean-up costs (investigation and remediation) when such amounts can reasonably be estimated and it is probable that the Company will be required to incur such costs. At September 30, 2010, the Company has estimated its remaining clean-up costs related to former manufactured gas plant sites and third party waste disposal sites will be in the range of $17.3 million to $21.5 million. The minimum estimated liability of $17.3 million has been recorded on the Consolidated Balance Sheet at September 30, 2010. The Company expects to recover its environmental clean-up costs through rate recovery. Other than as discussed in Note I (referred to below), the Company is currently not aware of any material additional exposure to environmental liabilities. However, changes in environmental regulations, new information or other factors could adversely impact the Company. For further discussion refer to Item 8 at Note I — Commitments and Contingencies under the heading “Environmental Matters.” Legislative and regulatory measures to address climate change and greenhouse gas emissions are in various phases of discussion or implementation. The EPA has determined that stationary sources of significant greenhouse gas emissions will be required under the federal Clean Air Act to obtain permits covering such emissions beginning in January 2011. In addition, the U.S. Congress has been considering bills that would 62 establish a cap-and-trade program to reduce emissions of greenhouse gases. Legislation or regulation that restricts carbon emissions could increase the Company’s cost of environmental compliance by requiring the Company to install new equipment to reduce emissions from larger facilities and/or purchase emission allowances. Climate change and greenhouse gas measures could also delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals with regard to existing and new facilities, or impose additional monitoring and reporting requirements. But legislation or regulation that sets a price on or otherwise restricts carbon emissions could also benefit the Company by increasing demand for natural gas, because substantially fewer carbon emissions per Btu of heat generated are associated with the use of natural gas than with certain alternate fuels such as coal and oil. The effect (material or not) on the Company of any new legislative or regulatory measures will depend on the particular provisions that are ultimately adopted. NEW AUTHORITATIVE ACCOUNTING AND FINANCIAL REPORTING GUIDANCE In September 2006, the FASB issued authoritative guidance for using fair value to measure assets and liabilities. This guidance serves to clarify the extent to which companies measure assets and liabilities at fair value, the information used to measure fair value, and the effect that fair-value measurements have on earnings. This guidance is to be applied whenever assets or liabilities are to be measured at fair value. On October 1, 2008, the Company adopted this guidance for financial assets and financial liabilities that are recognized or disclosed at fair value on a recurring basis. The FASB’s authoritative guidance for using fair value to measure nonfinancial assets and nonfinancial liabilities on a nonrecurring basis became effective during the quarter ended December 31, 2009. The Company’s nonfinancial assets and nonfinancial liabilities were not significantly impacted by this guidance during the year ended September 30, 2010. The Company had identified Goodwill as being the major nonfinancial asset that may have been impacted by the adoption of this guidance; however, the adoption of the guidance did not have a significant impact on the Company’s annual test for goodwill impairment. The Company had identified Asset Retirement Obligations as a nonfinancial liability that may have been impacted by the adoption of the guidance. The adoption of the guidance did not have a significant impact on the Company’s Asset Retirement Obligations. Refer to Item 8 at Note B — Asset Retirement Obligations for further disclosure. Additionally, in February 2010, the FASB issued updated guidance that includes additional requirements and disclosures regarding fair value measurements. The guidance now requires the gross presentation of activity within the Level 3 roll forward and requires disclosure of details on transfers in and out of Level 1 and 2 fair value measurements. It also provides further clarification on the level of disaggregation of fair value measurements and disclosures on inputs and valuation techniques. The Company has updated its disclosures to reflect the new requirements in Item 8 at Note F — Fair Value Measurements, except for the Level 3 roll forward gross presentation, which will be effective as of the Company’s first quarter of fiscal 2012. On December 31, 2008, the SEC issued a final rule on Modernization of Oil and Gas Reporting. The final rule modifies the SEC’s reporting and disclosure rules for oil and gas reserves and aligns the full cost accounting rules with the revised disclosures. The most notable changes of the final rule include the replacement of the single day period-end pricing used to value oil and gas reserves with an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. The final rule also permits voluntary disclosure of probable and possible reserves, a disclosure previously prohibited by SEC rules. Additionally, on January 6, 2010, the FASB amended the oil and gas accounting standards to conform to the SEC final rule on Modernization of Oil and Gas Reporting (final rule). The revised reporting and disclosure requirements became effective with this Form 10-K for the period ended September 30, 2010. The Company has updated its disclosures to reflect the new requirements in Item 8 at Note Q — Supplementary Information for Oil and Gas Producing Activities. The Company chose not to disclose probable and possible reserves. In order to estimate the effect of adopting the final rule, the Company would be required to prepare two sets of reserve reports (applying both the final rule and previous rules). There would be significant time and expense associated with preparing two sets of reports to address changes between the different rules. Since the information obtained from the dual reserve reports would be relevant only for transitional purposes, the cost is deemed to exceed the benefit. As a result, the Company has determined it would be impractical to estimate the impact of adoption of the final rule. 63 In March 2009, the FASB issued authoritative guidance that expands the disclosures required in an employer’s financial statements about pension and other post-retirement benefit plan assets. The additional disclosures include more details on how investment allocation decisions are made, the plan’s investment policies and strategies, the major categories of plan assets, the inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on changes in plan assets for the period, and disclosure regarding significant concentrations of risk within plan assets. The additional disclosure requirements became effective with this Form 10-K for the period ended September 30, 2010. The Company has updated its disclosures to reflect the new requirements in Item 8 at Note H — Retirement Plan and Other Post-Retirement Benefits. In June 2009, the FASB issued amended authoritative guidance to improve and clarify financial reporting requirements by companies involved with variable interest entities. The new guidance requires a company to perform an analysis to determine whether the company’s variable interest or interests give it a controlling financial interest in a variable interest entity. The analysis also assists in identifying the primary beneficiary of a variable interest entity. This authoritative guidance will be effective as of the Company’s first quarter of fiscal 2011. Given the current organizational structure of the Company, the Company does not believe this authoritative guidance will have any impact on its consolidated financial statements. EFFECTS OF INFLATION Although the rate of inflation has been relatively low over the past few years, the Company’s operations remain sensitive to increases in the rate of inflation because of its capital spending and the regulated nature of a significant portion of its business.

In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. As discussed in Note A to the consolidated financial statements, the Company changed the manner in which its oil and gas reserves are estimated, as well as the manner in which prices are determined to calculate the ceiling on capitalized oil and gas costs as of September 30, 2010. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The equity method is used to account for minority owned entities. All significant intercompany balances and transactions are eliminated. The Company uses proportionate consolidation when accounting for drilling arrangements related to oil and gas producing properties accounted for under the full cost method of accounting. The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Reclassification Certain prior year amounts have been reclassified to conform with current year presentation. Regulation The Company is subject to regulation by certain state and federal authorities. The Company has accounting policies which conform to GAAP, as applied to regulated enterprises, and are in accordance with the accounting requirements and ratemaking practices of the regulatory authorities. Reference is made to Note C — Regulatory Matters for further discussion. Revenue Recognition The Company’s Utility segment records revenue as bills are rendered, except that service supplied but not billed is reported as unbilled utility revenue and is included in operating revenues for the year in which service is furnished. The Company’s Energy Marketing segment records revenue as bills are rendered for service supplied on a monthly basis. The Company’s Pipeline and Storage segment records revenue for natural gas transportation and storage services. Revenue from reservation charges on firm contracted capacity is recognized through equal monthly charges over the contract period regardless of the amount of gas that is transported or stored. Commodity charges on firm contracted capacity and interruptible contracts are recognized as revenue when physical deliveries of natural gas are made at the agreed upon delivery point or when gas is injected or withdrawn from the storage field. The point of delivery into the pipeline or injection or withdrawal from storage is the point at which ownership and risk of loss transfers to the buyer of such transportation and storage services. The Company’s Exploration and Production segment records revenue based on entitlement, which means that revenue is recorded based on the actual amount of gas or oil that is delivered to a pipeline and the Company’s ownership interest in the producing well. If a production imbalance occurs between what was supposed to be delivered to a pipeline and what was actually produced and delivered, the Company accrues the difference as an imbalance. Allowance for Uncollectible Accounts The allowance for uncollectible accounts is the Company’s best estimate of the amount of probable credit losses in the existing accounts receivable. The allowance is determined based on historical experience, the age and other specific information about customer accounts. Account balances are charged off against the allowance twelve months after the account is final billed or when it is anticipated that the receivable will not be recovered. 73 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Regulatory Mechanisms The Company’s rate schedules in the Utility segment contain clauses that permit adjustment of revenues to reflect price changes from the cost of purchased gas included in base rates. Differences between amounts currently recoverable and actual adjustment clause revenues, as well as other price changes and pipeline and storage company refunds not yet includable in adjustment clause rates, are deferred and accounted for as either unrecovered purchased gas costs or amounts payable to customers. Such amounts are generally recovered from (or passed back to) customers during the following fiscal year. Estimated refund liabilities to ratepayers represent management’s current estimate of such refunds. Reference is made to Note C — Regulatory Matters for further discussion. The impact of weather on revenues in the Utility segment’s New York rate jurisdiction is tempered by a WNC, which covers the eight-month period from October through May. The WNC is designed to adjust the rates of retail customers to reflect the impact of deviations from normal weather. Weather that is warmer than normal results in a surcharge being added to customers’ current bills, while weather that is colder than normal results in a refund being credited to customers’ current bills. Since the Utility segment’s Pennsylvania rate jurisdiction does not have a WNC, weather variations have a direct impact on the Pennsylvania rate jurisdiction’s revenues. The impact of weather normalized usage per customer account in the Utility segment’s New York rate jurisdiction is tempered by a revenue decoupling mechanism. The effect of the revenue decoupling mechanism is to render the Company financially indifferent to throughput decreases resulting from conservation. Weather normalized usage per account that exceeds the average weather normalized usage per customer account results in a refund being credited to customers’ bills. Weather normalized usage per account that is below the average weather normalized usage per account results in a surcharge being added to customers’ bills. The surcharge or credit is calculated over a twelve- month period ending December 31st, and applied to customer bills annually, beginning March 1st. In the Pipeline and Storage segment, the allowed rates that Supply Corporation bills its customers are based on a straight fixed-variable rate design, which allows recovery of all fixed costs, including return on equity and income taxes, through fixed monthly reservation charges. Because of this rate design, changes in throughput due to weather variations do not have a significant impact on the revenues of Supply Corporation. Prior to December 10, 2008, the allowed rates that Empire billed its customers were based on a modified fixed-variable rate design, which recovered return on equity and income taxes through variable charges. Because of this rate design, changes in throughput due to weather variations could have had a significant impact on Empire’s revenues. On December 10, 2008, Empire became FERC regulated. As a result, Empire now bills its customers based on a straight fixed-variable rate design. Changes in throughput due to weather variations no longer have a significant impact on Empire’s revenue. Property, Plant and Equipment The principal assets of the Utility and Pipeline and Storage segments, consisting primarily of gas plant in service, are recorded at the historical cost when originally devoted to service in the regulated businesses, as required by regulatory authorities. In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Under this methodology, all costs associated with property acquisition, exploration and development activities are capitalized, including internal costs directly identified with acquisition, exploration and development activities. The internal costs that are capitalized do not include any costs related to production, general corporate overhead, or similar activities. The Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. 74 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Capitalized costs include costs related to unproved properties, which are excluded from amortization until proved reserves are found or it is determined that the unproved properties are impaired. All costs related to unproved properties are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is transferred to the pool of capitalized costs being amortized. Capitalized costs are subject to the SEC full cost ceiling test. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of 10%, which is computed by applying prices of oil and gas (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the latest balance sheet, less estimated future expenditures, plus (b) the cost of unevaluated properties not being depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. In accordance with the SEC final rule on Modernization of Oil and Gas Reporting, the natural gas and oil prices used to calculate the full cost ceiling (as of September 30, 2010) are based on an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. If capitalized costs, net of accumulated depreciation, depletion and amortization and related deferred income taxes, exceed the ceiling at the end of any quarter, a permanent impairment is required to be charged to earnings in that quarter. In adjusting estimated future net cash flows for hedging under the ceiling test at September 30, 2010, 2009, and 2008, estimated future net cash flows were increased by $65.4 million, $143.3 million and $34.5 million, respectively. The Company’s capitalized costs exceeded the full cost ceiling for the Company’s oil and gas properties at December 31, 2008. As such, the Company recognized a pre-tax impairment of $182.8 million at December 31, 2008 (utilizing period end pricing as required by the SEC full cost rules then in effect). Deferred income taxes of $74.6 million were recorded associated with this impairment. Maintenance and repairs of property and replacements of minor items of property are charged directly to maintenance expense. The original cost of the regulated subsidiaries’ property, plant and equipment retired, and the cost of removal less salvage, are charged to accumulated depreciation. Depreciation, Depletion and Amortization For oil and gas properties, depreciation, depletion and amortization is computed based on quantities produced in relation to proved reserves using the units of production method. The cost of unproved oil and gas properties is excluded from this computation. In the All Other category, for timber properties, depletion, determined on a property by property basis, is charged to operations based on the actual amount of timber cut in relation to the total amount of recoverable timber. For all other property, plant and equipment, depreciation, depletion and amortization is computed using the straight-line method in amounts sufficient to recover costs over the estimated service lives of property in service. The following is a summary of depreciable plant by segment: As of September 30 2010 2009 (Thousands) Utility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $1,657,686 1,241,179 Pipeline and Storage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2,294,235 Exploration and Production . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1,634 Energy Marketing. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 127,939 All Other and Corporate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $1,616,908 1,196,937 1,972,353 1,241 154,512 $5,322,673 $4,941,951 75 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Average depreciation, depletion and amortization rates are as follows: Year Ended September 30 2010 2008 2009 Utility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

As disclosed in Note Q — Supplementary Information for Oil and Gas Producing Properties, depletion of oil and gas producing properties amounted to $2.10, $2.10 and $2.23 per Mcfe of production in 2010, 2009 and 2008, respectively. Goodwill The Company has recognized goodwill of $5.5 million as of September 30, 2010, 2009 and 2008 on its Consolidated Balance Sheets related to the Company’s acquisition of Empire in 2003. The Company accounts for goodwill in accordance with the current authoritative guidance, which requires the Company to test goodwill for impairment annually. At September 30, 2010, 2009 and 2008, the fair value of Empire was greater than its book value. As such, the goodwill was not considered impaired at those dates. Going back to the origination of the goodwill in 2003, the Company has never recorded an impairment of its goodwill balance. Financial Instruments Unrealized gains or losses from the Company’s investments in an equity mutual fund and the stock of an insurance company (securities available for sale) are recorded as a component of accumulated other comprehensive income (loss). Reference is made to Note G — Financial Instruments for further discussion. The Company uses a variety of derivative financial instruments to manage a portion of the market risk associated with fluctuations in the price of natural gas and crude oil. These instruments include price swap agreements and futures contracts. The Company accounts for these instruments as either cash flow hedges or fair value hedges. In both cases, the fair value of the instrument is recognized on the Consolidated Balance Sheets as either an asset or a liability labeled Fair Value of Derivative Financial Instruments. Reference is made to Note F — Fair Value Measurements for further discussion concerning the fair value of derivative financial instruments. For effective cash flow hedges, the offset to the asset or liability that is recorded is a gain or loss recorded in accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. The gain or loss recorded in accumulated other comprehensive income (loss) remains there until the hedged transaction occurs, at which point the gains or losses are reclassified to operating revenues or purchased gas expense on the Consolidated Statements of Income. Any ineffectiveness associated with the cash flow hedges is recorded in the Consolidated Statements of Income. The Company did not experience any material ineffectiveness with regard to its cash flow hedges during 2010, 2009 or 2008. For fair value hedges, the offset to the asset or liability that is recorded is a gain or loss recorded to operating revenues or purchased gas expense on the Consolidated Statements of Income. However, in the case of fair value hedges, the Company also records an asset or liability on the Consolidated Balance Sheets representing the change in fair value of the asset or firm commitment that is being hedged (see Other Current Assets section in this footnote). The offset to this asset or liability is a gain or loss recorded to operating revenues or purchased gas expense on the Consolidated Statements of Income as well. If the fair value hedge is effective, the gain or loss 76 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) from the derivative financial instrument is offset by the gain or loss that arises from the change in fair value of the asset or firm commitment that is being hedged. The Company did not experience any material ineffectiveness with regard to its fair value hedges during 2010, 2009 or 2008. Accumulated Other Comprehensive Income (Loss) The components of Accumulated Other Comprehensive Income (Loss) are as follows: Year Ended September 30 2010 2009 (Thousands) Funded Status of the Pension and Other Post-Retirement Benefit Plans . . $(79,465) (51) Cumulative Foreign Currency Translation Adjustment . . . . . . . . . . . . . . . 32,876 Net Unrealized Gain on Derivative Financial Instruments . . . . . . . . . . . . 1,655 Net Unrealized Gain on Securities Available for Sale . . . . . . . . . . . . . . . . $(63,802) (104) 18,491 3,019 Accumulated Other Comprehensive Loss. . . . . . . . . . . . . . . . . . . . . . . . . $(44,985) $(42,396) At September 30, 2010, it is estimated that of the $32.9 million net unrealized gain on derivative financial instruments shown in the table above, $23.6 million of unrealized gains will be reclassified into the Consolidated Statement of Income during 2011. The remaining unrealized gains on derivative financial instruments of $9.3 million will be reclassified into the Consolidated Statement of Income in subsequent years. The Company’s derivative financial instruments extend out to 2014. The amounts included in accumulated other comprehensive income (loss) related to the funded status of the Company’s pension and other post-retirement benefit plans consist of prior service costs and accumulated losses. The total amount for prior service costs was $0.3 million at September 30, 2010 and 2009. The total amount for accumulated losses was $79.2 million and $63.5 million at September 30, 2010 and 2009, respectively. Gas Stored Underground — Current In the Utility segment, gas stored underground — current in the amount of $24.9 million is carried at lower of cost or market, on a LIFO method. Based upon the average price of spot market gas purchased in September 2010, including transportation costs, the current cost of replacing this inventory of gas stored underground — current exceeded the amount stated on a LIFO basis by approximately $82.5 million at September 30, 2010. All other gas stored underground — current, which is in the Energy Marketing segment, is carried at an average cost method, subject to lower of cost or market adjustments. Purchased Timber Cutting Rights In September 2010, the Company sold all of its purchased timber cutting rights in connection with the sale of its sawmill in Marienville, Pennsylvania. The Company continues to maintain a forestry operation, but will no longer be processing lumber products. Prior to the sale, the Company purchased the right to harvest timber from land owned by other parties. These rights, which extended from several months to several years, were purchased to ensure an adequate supply of timber for the Company’s sawmill and kiln operations. The historical value of timber rights expected to be harvested during the following year were included in Materials and Supplies on the Consolidated Balance Sheets while the historical value of timber rights expected to be harvested beyond one 77 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) year were included in Other Assets on the Consolidated Balance Sheets.

Costs associated with the reacquisition of debt related to rate-regulated subsidiaries are deferred and amortized over the remaining life of the issue or the life of the replacement debt in order to match regulatory treatment. Foreign Currency Translation The functional currency for the Company’s foreign operations is the local currency of the country where the operations are located. Asset and liability accounts are translated at the rate of exchange on the balance sheet date. Revenues and expenses are translated at the average exchange rate during the period. Foreign currency translation adjustments are recorded as a component of accumulated other comprehensive income (loss). With the sale of SECI on August 31, 2007, the Company eliminated its major foreign operation. While the Company is in the process of winding up or selling certain power development projects in Europe, the investment in such projects is not significant and the Company does not expect to have any significant foreign currency translation adjustments in the future. Income Taxes The Company and its domestic subsidiaries file a consolidated federal income tax return. Investment tax credit, prior to its repeal in 1986, was deferred and is being amortized over the estimated useful lives of the related property, as required by regulatory authorities having jurisdiction. Consolidated Statements of Cash Flows For purposes of the Consolidated Statements of Cash Flows, the Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. At September 30, 2010, the Company accrued $55.5 million of capital expenditures in the Exploration and Production segment, the majority of which was in the Appalachian region. This amount was excluded from the Consolidated Statement of Cash Flows at September 30, 2010 since it represented a non-cash investing activity at that date. At September 30, 2009, the Company accrued $9.1 million of capital expenditures in the Exploration and Production segment, the majority of which was in the Appalachian region. The Company also accrued $0.7 million of capital expenditures in the All Other category related to the construction of the Midstream Covington Gathering System at September 30, 2009. These amounts were excluded from the Consolidated Statement of Cash Flows at September 30, 2009 since they represent non-cash investing activities at that date. These capital expenditures were paid during the quarter ended December 31, 2009 and have been included in the Consolidated Statement of Cash Flows for the year ended September 30, 2010. 78 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) At September 30, 2008, the Company accrued $16.8 million of capital expenditures related to the construction of the Empire Connector project. This amount was excluded from the Consolidated Statement of Cash Flows at September 30, 2008 since it represented a non-cash investing activity at that date. These capital expenditures were paid during the quarter ended December 31, 2008 and have been included in the Consolidated Statement of Cash Flows for the year ended September 30, 2009. Hedging Collateral Account This is an account title for cash held in margin accounts funded by the Company to serve as collateral for hedging positions. At September 30, 2010, the Company had hedging collateral deposits of $10.1 million related to its exchange-traded futures contracts and $1.0 million related to its over-the-counter crude oil swap agreements. At September 30, 2009, the Company had hedging collateral deposits of $0.8 million related to its exchange-traded futures contracts. In accordance with its accounting policy, the Company does not offset hedging collateral deposits paid or received against related derivative financial instrument liability or asset balances. Cash Held in Escrow On July 20, 2009, the Company’s wholly-owned subsidiary in the Exploration and Production segment, Seneca, acquired Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million in cash (including cash acquired of $4.3 million). The cash acquired at acquisition includes $2 million held in escrow at September 30, 2010 and 2009. Seneca placed this amount in escrow as part of the purchase price. Currently, the Company and Ivanhoe Energy are negotiating a final resolution to the issue of whether Ivanhoe Energy is entitled to some or all of the amount held in escrow. On August 31, 2007, the Company received approximately $232.1 million of proceeds from the sale of SECI, of which $58.0 million was placed in escrow pending receipt of a tax clearance certificate from the Canadian government. The escrow account was a Canadian dollar denominated account. On a U.S. dollar basis, the value of this account was $62.0 million at September 30, 2007. In December 2007, the Canadian government issued the tax clearance certificate, thereby releasing the proceeds from restriction as of December 31, 2007. To hedge against foreign currency exchange risk related to the cash being held in escrow, the Company held a forward contract to sell Canadian dollars. For presentation purposes on the Consolidated Statement of Cash Flows, for the year ended September 30, 2008, the Cash Held in Escrow line item within Investing Activities reflects the net proceeds to the Company (received on January 8, 2008) after adjusting for the impact of the foreign currency hedge.

Monthly payments under the balanced billing programs are typically higher than current month usage during the summer months. During the winter months, monthly payments under the balanced billing programs are typically lower than current month usage. At September 30, 2010 and 2009, customers in the balanced billing programs had advanced excess funds of $27.6 million and $24.6 million, respectively. Customer Security Deposits The Company, in its Utility, Pipeline and Storage, and Energy Marketing segments, often times requires security deposits from marketers, producers, pipeline companies, and commercial and industrial customers before providing services to such customers. At September 30, 2010 and 2009, the Company had received customer security deposits amounting to $18.3 million and $17.4 million, respectively. Earnings Per Common Share Basic earnings per common share is computed by dividing income available for common stock by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. For purposes of determining earnings per common share, the only potentially dilutive securities the Company has outstanding are stock options and SARs. The diluted weighted average shares outstanding shown on the Consolidated Statements of Income reflects the potential dilution as a result of these stock options and SARs as determined using the Treasury Stock Method. Stock options and SARs that are antidilutive are excluded from the calculation of diluted earnings per common share. For 2010, there were 314,910 SARs excluded as being antidilutive, and there were no stock options excluded as being antidilutive. For 2009, there were 365,000 SARs and 765,000 stock options excluded as being antidilutive. For 2008, there were 7,344 SARs excluded as being antidilutive, and there were no stock options excluded as being antidilutive. Share Repurchases The Company considers all shares repurchased as cancelled shares restored to the status of authorized but unissued shares, in accordance with New Jersey law. The repurchases are accounted for on the date the share repurchase is settled as an adjustment to common stock (at par value) with the excess repurchase price allocated between paid in capital and retained earnings. Refer to Note E — Capitalization and Short-Term Borrowings for further discussion of the share repurchase program. Stock-Based Compensation The Company has various stock option and stock award plans which provide or provided for the issuance of one or more of the following to key employees: incentive stock options, nonqualified stock options, SARs, restricted stock, restricted stock units, performance units or performance shares. Stock options and SARs under all plans have exercise prices equal to the average market price of Company common stock on the date of grant, and generally no stock option or SAR is exercisable less than one year or more than ten years after the date of each grant. Restricted stock is subject to restrictions on vesting and transferability. Restricted stock awards entitle the participants to full dividend and voting rights. Certificates for shares of restricted stock awarded under the Company’s stock option and stock award plans are held by the Company during the periods in which the restrictions on vesting are effective. Restrictions on restricted stock awards generally lapse ratably over a period of not more than ten years after the date of each grant. 80 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The Company follows authoritative guidance which requires the measurement and recognition of compensation cost at fair value for all share-based payments, including stock options and SARs. The Company has chosen the Black-Scholes-Merton closed form model to calculate the compensation expense associated with such share-based payments since it is easier to administer than the Binomial option-pricing model. Furthermore, since the Company does not have complex stock-based compensation awards, it does not believe that compensation expense would be materially different under either model. The Company granted 520,500, 610,000 and 321,000 performance based SARs during the years ended September 30, 2010, 2009 and 2008, respectively. The Company did not grant any stock options or non- performance based SARs during the years ended September 30, 2010, 2009 and 2008. The accounting treatment for performance based and non-performance based SARs is the same as the accounting for stock options under the current authoritative guidance for stock-based compensation. The performance based SARs granted for the years ended September 30, 2010 and 2009 vest and become exercisable annually in one-third increments, provided that a performance condition is met. The performance condition for each fiscal year, generally stated, is an increase over the prior fiscal year of at least five percent in certain oil and natural gas production of the Exploration and Production segment. The performance based SARs granted for the year ended September 30, 2008 vest and become exercisable annually, in one-third increments, provided that a performance condition for diluted earnings per share is met for the prior fiscal year. The weighted average grant date fair value of the performance based SARs granted during 2010, 2009 and 2008 was estimated on the date of grant using the same accounting treatment that is applied for stock options, and assumes that the performance conditions specified will be achieved. If such conditions are not met or it is not considered probable that such conditions will be met, no compensation expense is recognized and any previously recognized compensation expense is reversed. During 2009, the Company reversed $0.5 million of previously recognized compensation expense associated with performance based SARs. The Company also granted 4,000, 63,000, and 25,000 restricted share awards (non-vested stock as defined by the current accounting literature) during the years ended September 30, 2010, 2009 and 2008, respectively. Stock-based compensation expense for the years ended September 30, 2010, 2009 and 2008 was approximately $4.4 million, $2.1 million (net of the $0.5 million reversal of compensation expense discussed above), and $2.3 million, respectively. Stock-based compensation expense is included in operation and maintenance expense on the Consolidated Statement of Income. The total income tax benefit related to stock-based compensation expense during the years ended September 30, 2010, 2009 and 2008 was approximately $1.8 million, $0.8 million and $0.9 million, respectively. There were no capitalized stock-based compensation costs during the years ended September 30, 2010, 2009 and 2008. Stock Options The total intrinsic value of stock options exercised during the years ended September 30, 2010, 2009 and 2008 totaled approximately $53.6 million, $18.7 million, and $24.6 million, respectively. For 2010, 2009 and 2008, the amount of cash received by the Company from the exercise of such stock options was approximately $34.5 million, $29.2 million, and $18.5 million, respectively. The Company realizes tax benefits related to the exercise of stock options on a calendar year basis as opposed to a fiscal year basis. As such, for stock options exercised during the quarters ended December 31, 2009, 2008, and 2007, the Company realized a tax benefit of $8.0 million, $1.6 million, and $4.4 million, respectively. For stock options exercised during the period of January 1, 2010 through September 30, 2010, the Company will realize a tax benefit of approximately $13.3 million in the quarter ended December 31, 2010. For stock options exercised during the period of January 1, 2009 through September 30, 2009, the Company realized a tax benefit of approximately $5.7 million in the quarter ended December 31, 2009. For stock options exercised during the period of January 1, 2008 through September 30, 2008, the Company realized a tax benefit of approximately $4.3 million in the quarter ended December 31, 2008. As stated above, there were no stock 81 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) options granted during the years ended September 30, 2010, 2009 and 2008. For the years ended September 30, 2010, 2009 and 2008, 100,000, 27,000 and 358,000 stock options became fully vested, respectively. The total fair value of the stock options that became vested during the years ended September 30, 2010, 2009 and 2008 was approximately $0.7 million, $0.2 million and $2.6 million, respectively. As of September 30, 2010, there was no unrecognized compensation expense related to stock options. For a summary of transactions during 2010 involving option shares for all plans, refer to Note E — Capitalization and Short-Term Borrowings. Non-Performance Based SARs Participants in the stock option and award plans did not exercise any non-performance based SARs during the years ended September 30, 2010, 2009 and 2008. As stated above, the Company did not grant any non- performance based SARs during the years ended September 30, 2010, 2009 and 2008. For the year ended September 30, 2010, 50,000 non-performance based SARs became fully vested. Fiscal 2010 was the first year in which non-performance based SARs became vested. The total fair value of the non-performance based SARs that became vested during the year ended September 30, 2010 was approximately $0.4 million. As of September 30, 2010, there was no unrecognized compensation expense related to non-performance based SARs. For a summary of transactions during 2010 involving non-performance based SARs for all plans, refer to Note E — Capitalization and Short-Term Borrowings. Performance Based SARs Participants in the stock option and award plans did not exercise any performance based SARs during the years ended September 30, 2010, 2009 and 2008. As stated above, there were 520,500, 610,000 and 321,000 performance based SARs granted during the years ended September 30, 2010, 2009 and 2008, respectively. The weighted average grant date fair value of performance based SARs granted in 2010, 2009 and 2008 is $12.06 per share, $4.09 per share and $9.06 per share, respectively. For the years ended September 30, 2010 and 2009, 203,324 and 96,984 performance based SARs became fully vested. Fiscal 2009 was the first year in which performance based SARs became vested. The total fair value of the performance based SARs that became vested during each of the years ended September 30, 2010 and 2009 was approximately $0.8 million. As of September 30, 2010, unrecognized compensation expense related to performance based SARs totaled approximately $4.0 million, which will be recognized over a weighted average period of 10.3 months. For a summary of transactions during 2010 involving performance based SARs for all plans, refer to Note E — Capitalization and Short-Term Borrowings. The fair value of performance based SARs at the date of grant was estimated using the Black-Scholes- Merton closed form model.

The expected life and expected volatility are based on historical experience. For grants during the years ended September 30, 2010, 2009 and 2008, it was assumed that there would be no forfeitures, based on the vesting term and the number of grantees. 82 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Restricted Share Awards The weighted average fair value of restricted share awards granted in 2010, 2009 and 2008 is $52.10 per share, $47.46 per share and $48.41 per share, respectively. As of September 30, 2010, unrecognized compensation expense related to restricted share awards totaled approximately $3.4 million, which will be recognized over a weighted average period of 4.0 years. For a summary of transactions during 2010 involving restricted share awards, refer to Note E — Capitalization and Short-Term Borrowings. New Authoritative Accounting and Financial Reporting Guidance In September 2006, the FASB issued authoritative guidance for using fair value to measure assets and liabilities. This guidance serves to clarify the extent to which companies measure assets and liabilities at fair value, the information used to measure fair value, and the effect that fair-value measurements have on earnings. This guidance is to be applied whenever assets or liabilities are to be measured at fair value. On October 1, 2008, the Company adopted this guidance for financial assets and financial liabilities that are recognized or disclosed at fair value on a recurring basis. The FASB’s authoritative guidance for using fair value to measure nonfinancial assets and nonfinancial liabilities on a nonrecurring basis became effective during the quarter ended December 31, 2009. The Company’s nonfinancial assets and nonfinancial liabilities were not significantly impacted by this guidance during the year ended September 30, 2010. The Company had identified Goodwill as being the major nonfinancial asset that may have been impacted by the adoption of this guidance; however, the adoption of the guidance did not have a significant impact on the Company’s annual test for goodwill impairment. The Company had identified Asset Retirement Obligations as a nonfinancial liability that may have been impacted by the adoption of the guidance. The adoption of the guidance did not have a significant impact on the Company’s Asset Retirement Obligations. Refer to Note B — Asset Retirement Obligations for further disclosure. Additionally, in February 2010, the FASB issued updated guidance that includes additional requirements and disclosures regarding fair value measurements. The guidance now requires the gross presentation of activity within the Level 3 roll forward and requires disclosure of details on transfers in and out of Level 1 and 2 fair value measurements. It also provides further clarification on the level of disaggregation of fair value measurements and disclosures on inputs and valuation techniques. The Company has updated its disclosures to reflect the new requirements in Note F — Fair Value Measurements, except for the Level 3 roll forward gross presentation, which will be effective as of the Company’s first quarter of fiscal 2012. On December 31, 2008, the SEC issued a final rule on Modernization of Oil and Gas Reporting. The final rule modifies the SEC’s reporting and disclosure rules for oil and gas reserves and aligns the full cost accounting rules with the revised disclosures. The most notable changes of the final rule include the replacement of the single day period-end pricing used to value oil and gas reserves with an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. The final rule also permits voluntary disclosure of probable and possible reserves, a disclosure previously prohibited by SEC rules. Additionally, on January 6, 2010, the FASB amended the oil and gas accounting standards to conform to the SEC final rule on Modernization of Oil and Gas Reporting (final rule). The revised reporting and disclosure requirements became effective with this Form 10-K for the period ended September 30, 2010. The Company has updated its disclosures to reflect the new requirements in Note Q — Supplementary Information for Oil and Gas Producing Activities. The Company chose not to disclose probable and possible reserves. In order to estimate the effect of adopting the final rule, the Company would be required to prepare two sets of reserve reports (applying both the final rule and previous rules). There would be significant time and expense associated with preparing two sets of reports to address changes between the different rules. Since the information obtained from the dual reserve reports would be relevant only for transitional purposes, the cost is deemed to exceed the benefit. As a result, the Company has determined it would be impractical to estimate the impact of adoption of the final rule. 83 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) In March 2009, the FASB issued authoritative guidance that expands the disclosures required in an employer’s financial statements about pension and other post-retirement benefit plan assets. The additional disclosures include more details on how investment allocation decisions are made, the plan’s investment policies and strategies, the major categories of plan assets, the inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on changes in plan assets for the period, and disclosure regarding significant concentrations of risk within plan assets. The additional disclosure requirements became effective with this Form 10-K for the period ended September 30, 2010. The Company has updated its disclosures to reflect the new requirements in Note H — Retirement Plan and Other Post-Retirement Benefits. In June 2009, the FASB issued amended authoritative guidance to improve and clarify financial reporting requirements by companies involved with variable interest entities. The new guidance requires a company to perform an analysis to determine whether the company’s variable interest or interests give it a controlling financial interest in a variable interest entity. The analysis also assists in identifying the primary beneficiary of a variable interest entity. This authoritative guidance will be effective as of the Company’s first quarter of fiscal 2011. Given the current organizational structure of the Company, the Company does not believe this authoritative guidance will have any impact on its consolidated financial statements. Note B — Asset Retirement Obligations The Company accounts for asset retirement obligations in accordance with the authoritative guidance that requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. An asset retirement obligation is defined as a legal obligation associated with the retirement of a tangible long-lived asset in which the timing and/or method of settlement may or may not be conditional on a future event that may or may not be within the control of the Company. When the liability is initially recorded, the entity capitalizes the estimated cost of retiring the asset as part of the carrying amount of the related long- lived asset. Over time, the liability is adjusted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. The Company estimates the fair value of its asset retirement obligations based on the discounting of expected cash flows using various estimates, assumptions and judgments regarding certain factors such as the existence of a legal obligation for an asset retirement obligation; estimated amounts and timing of settlements; the credit-adjusted risk-free rate to be used; and inflation rates. Asset retirement obligations incurred in the current period were Level 3 fair value measurements as the inputs used to measure the fair value are unobservable. As previously disclosed, the Company follows the full cost method of accounting for its exploration and production costs. In accordance with the current authoritative guidance for asset retirement obligations, the Company has recorded an asset retirement obligation representing plugging and abandonment costs associated with the Exploration and Production segment’s crude oil and natural gas wells and has capitalized such costs in property, plant and equipment (i.e. the full cost pool). Under the current authoritative guidance for asset retirement obligations, since plugging and abandonment costs are already included in the full cost pool, the units-of-production depletion calculation excludes from the depletion base any estimate of future plugging and abandonment costs that are already recorded in the full cost pool. The full cost method of accounting provides a limit to the amount of costs that can be capitalized in the full cost pool. This limit is referred to as the full cost ceiling. In accordance with current authoritative guidance, since the full cost pool includes an amount associated with plugging and abandoning the wells, as discussed in the preceding paragraph, the calculation of the full cost ceiling no longer reduces the future net cash flows from proved oil and gas reserves by an estimate of plugging and abandonment costs. In addition to the asset retirement obligation recorded in the Exploration and Production segment, the Company has recorded future asset retirement obligations associated with the plugging and abandonment of natural gas storage wells in the Pipeline and Storage segment and the removal of asbestos and asbestos-containing material in 84 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) various facilities in the Utility and Pipeline and Storage segments. The Company has also recorded asset retirement obligations for certain costs connected with the retirement of the distribution mains and services components of the pipeline system in the Utility segment and with the transmission mains and other components in the pipeline system in the Pipeline and Storage segment. These retirement costs within the distribution and transmission systems are primarily for the capping and purging of pipe, which are generally abandoned in place when retired, as well as for the clean-up of PCB contamination associated with the removal of certain pipe.

There are a few exceptions to this rule. For example, the Company does earn a return on Unrecovered Purchased Gas Costs and, in the New York jurisdiction of its Utility segment, earns a return, within certain parameters, on the excess of cumulative funding to the pension plan over the cumulative amount collected in rates. (2) Included in Other Regulatory Assets on the Consolidated Balance Sheets. (3) Included in Other Regulatory Liabilities on the Consolidated Balance Sheets. If for any reason the Company ceases to meet the criteria for application of regulatory accounting treatment for all or part of its operations, the regulatory assets and liabilities related to those portions ceasing to meet such criteria would be eliminated from the Consolidated Balance Sheets and included in income of the period in which the discontinuance of regulatory accounting treatment occurs. Such amounts would be classified as an extraordinary item. Cost of Removal Regulatory Liability In the Company’s Utility and Pipeline and Storage segments, costs of removing assets (i.e. asset retirement costs) are collected from customers through depreciation expense. These amounts are not a legal retirement obligation as discussed in Note B — Asset Retirement Obligations. Rather, they are classified as a regulatory liability in recognition of the fact that the Company has collected dollars from the customer that will be used in the future to fund asset retirement costs. Tax Benefit on Medicare Part D Subsidy The Company has established a regulatory liability for the tax benefit it will receive under the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the Act) amounting to $4.8 million and $28.8 million at September 30, 2010 and 2009, respectively. The Act provides a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. The Company reduced its deferred tax asset relating to the Medicare Part D subsidy by $27.5 million to reflect changes made by the fundamental health care reform legislation enacted on March 23, 2010. In conjunction with the reduction of the deferred tax asset, the Company reduced its Medicare Part D regulatory liability by $27.5 million. In the Company’s Utility and Pipeline and Storage segments, the Company’s post-retirement benefit plans are funded by a component of tariff rates charged to customers. As such, prior to the fundamental health care reform legislation, the $27.5 million tax benefit had been recorded as a regulatory liability in anticipation of flowing that tax benefit back to customers through adjusted tariff rates. Refer to Note H — Retirement Plan and Other Post-Retirement Benefits for further discussion of the Act and its impact on the Company. Deferred Insurance Proceeds The Company, in its Pipeline and Storage segment, has deferred environmental insurance settlement proceeds amounting to $2.4 million and $3.8 million at September 30, 2010 and 2009, respectively. Such proceeds have been deferred as a regulatory liability to be applied against any future environmental claims that may be incurred. The proceeds have been classified as a regulatory liability in recognition of the fact that customers funded the premiums on the former insurance policies. NYPSC Assessment On April 7, 2009, the Governor of the State of New York signed into law an amendment to the Public Service Law increasing the allowed utility assessment from the then current rate of one-third of one percent to one percent of a utility’s in-state gross operating revenue, together with a temporary surcharge (expiring March 31, 2014) equal, as applied, to an additional one percent of the utility’s in-state gross operating revenue. 86 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The NYPSC, in a generic proceeding initiated for the purpose of implementing the amended law, has authorized the recovery, through rates, of the full cost of the increased assessment. The assessment is currently being applied to customer bills in the Utility segment’s New York jurisdiction. Off-System Sales and Capacity Release Credits The Company, in its Utility segment, has entered into off-system sales and capacity release transactions. Most of the margins on such transactions are returned to the customer with only a small percentage being retained by the Company. The amount owed to the customer has been deferred as a regulatory liability.

Also, regulatory assets representing future amounts collectible from customers, corresponding to additional deferred income taxes not previously recorded because of prior ratemaking practices, amounted to $149.7 million and $138.4 million at September 30, 2010 and 2009, respectively. Included in the above are regulatory liabilities and assets relating to the tax accounting method change noted below. The amounts are as follows: regulatory liabilities of $47.3 million as of September 30, 2010 and 2009, and regulatory assets of $56.3 million and $51.1 million as of September 30, 2010 and 2009, respectively. The Company reduced its deferred tax asset relating to the Medicare Part D subsidy by $27.5 million to reflect changes made by the fundamental health care reform legislation enacted on March 23, 2010. In conjunction with the reduction of the deferred tax asset, the Company reduced its Medicare Part D regulatory liability by $27.5 million. In the Company’s Utility and Pipeline and Storage segments, the Company’s post-retirement benefit plans are funded by a component of tariff rates charged to customers. As such, prior to the fundamental health care reform legislation, the $27.5 million tax benefit had been recorded as a regulatory liability in anticipation of flowing that tax benefit back to customers through adjusted tariff rates. The Company adopted the FASB authoritative guidance for income tax uncertainties on October 1, 2007. As of the date of adoption, a cumulative effect adjustment was recorded that resulted in a decrease to retained earnings of $0.4 million. Upon adoption, the unrecognized tax benefits were $1.7 million. 88 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The following is a reconciliation of the change in unrecognized tax benefits: Balance at Beginning of Year . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $8,721 699 Additions for Tax Positions Related to Current Year . . . . . . . . . . . .

The Company anticipates that the unrecognized tax benefits will not significantly change within the next twelve months. The Company recognizes interest relating to income taxes in Other Interest Expense and penalties relating to income taxes in Other Income. The Company recognized interest expense relating to income taxes of $0.2 million, $0.0 million and $0.5 million for fiscal 2010, 2009 and 2008, respectively. The Company has not accrued any penalties during fiscal 2010, 2009 and 2008. The Company files U.S. federal and various state income tax returns. The Internal Revenue Service (IRS) is currently conducting an examination of the Company for fiscal 2009 and fiscal 2010 in accordance with the Compliance Assurance Process (“CAP”). The CAP audit employs a real time review of the Company’s books and tax records by the IRS that is intended to permit issue resolution prior to the filing of the tax return. While the federal statute of limitations remains open for fiscal 2007 and later years, IRS examinations for fiscal 2008 and prior years have been completed and the Company believes such years are effectively settled. During fiscal 2009, consent was received from the IRS National Office approving the Company’s application to change its tax method of accounting for certain capitalized costs relating to its utility property. During this year, local IRS examiners proposed to disallow most of the accounting method change. The Company has filed a protest with the IRS Appeals Office disputing the local IRS findings. The Company is also subject to various routine state income tax examinations. The Company’s operating subsidiaries mainly operate in four states which have statutes of limitations that generally expire between three to four years from the date of filing of the income tax return. As of September 30, 2010, the Company has a federal net operating loss carryover of $19.7 million, which expires in varying amounts between 2023 and 2029. Although this loss carryover is subject to certain annual limitations, no valuation allowance was recorded because of management’s determination that the amount will be fully utilized during the carryforward period. 89 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Note E — Capitalization and Short-Term Borrowings Summary of Changes in Common Stock Equity Common Stock Shares Amount Paid In Capital Earnings Reinvested in the Business Accumulated Other Comprehensive Income (Loss) (Thousands, except per share amounts) Balance at September 30, 2007 . . . . . . . . . 83,461 Net Income Available for Common Stock . .

(2) Paid in Capital includes compensation costs associated with stock option, SARs and/or restricted stock awards. The expense is included within Net Income Available For Common Stock, net of tax benefits. 90 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) (3) The availability of consolidated earnings reinvested in the business for dividends payable in cash is limited under terms of the indentures covering long-term debt. At September 30, 2010, $919.1 million of accumulated earnings was free of such limitations. Common Stock The Company has various plans which allow shareholders, employees and others to purchase shares of the Company common stock. The National Fuel Gas Company Direct Stock Purchase and Dividend Reinvestment Plan allows shareholders to reinvest cash dividends and make cash investments in the Company’s common stock and provides investors the opportunity to acquire shares of the Company common stock without the payment of any brokerage commissions in connection with such acquisitions. The 401(k) Plans allow employees the opportunity to invest in the Company common stock, in addition to a variety of other investment alternatives. Generally, at the discretion of the Company, shares purchased under these plans are either original issue shares purchased directly from the Company or shares purchased on the open market by an independent agent. During 2010, the Company issued 1,975,853 original issue shares of common stock as a result of stock option exercises and 4,000 original issue shares for restricted stock awards (non-vested stock as defined by the current accounting literature for stock-based compensation). Holders of stock options or restricted stock will often tender shares of common stock to the Company for payment of option exercise prices and/or applicable withholding taxes. During 2010, 417,987 shares of common stock were tendered to the Company for such purposes. The Company considers all shares tendered as cancelled shares restored to the status of authorized but unissued shares, in accordance with New Jersey law. The Company also has a director stock program under which it issues shares of Company common stock to the non-employee directors of the Company who receive compensation under the Company’s Retainer Policy for Non-Employee Directors, as partial consideration for the directors’ services during the fiscal year. Under this program, the Company issued 13,689 original issue shares of common stock during 2010. In December 2005, the Company’s Board of Directors authorized the Company to implement a share repurchase program, whereby the Company may repurchase outstanding shares of common stock, up to an aggregate amount of eight million shares in the open market or through privately negotiated transactions. The Company completed the repurchase of the eight million shares during 2008 for a total program cost of $324.2 million (of which 4,165,122 shares were repurchased during the year ended September 30, 2008 for $191.0 million). In September 2008, the Company’s Board of Directors authorized the repurchase of an additional eight million shares. Under this new authorization, the Company repurchased 1,028,981 shares for $46.0 million through September 17, 2008. The Company, however, stopped repurchasing shares after September 17, 2008 in light of the unsettled nature of the credit markets. Since that time, the Company has increased its emphasis on Marcellus Shale development and pipeline expansion. As such, the Company does not anticipate repurchasing any shares in the near future. The share repurchases mentioned above were funded with cash provided by operating activities and/or through the use of the Company’s lines of credit. Shareholder Rights Plan In 1996, the Company’s Board of Directors adopted a shareholder rights plan (Plan). The Plan has been amended several times since it was adopted and is now embodied in an Amended and Restated Rights Agreement effective December 4, 2008, a copy of which was included as an exhibit to the Form 8-K filed by the Company on December 4, 2008. Pursuant to the Plan, the holders of the Company’s common stock have one right (Right) for each of their shares. Each Right is initially evidenced by the Company’s common stock certificates representing the outstanding shares of common stock. 91 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The Rights have anti-takeover effects because they will cause substantial dilution of the Company’s common stock if a person attempts to acquire the Company on terms not approved by the Board of Directors (an Acquiring Person). The Rights become exercisable upon the occurrence of a Distribution Date as described below, but after a Distribution Date Rights that are owned by an Acquiring Person will be null and void. At any time following a Distribution Date, each holder of a Right may exercise its right to receive, upon payment of an amount calculated under the Rights Agreement, common stock of the Company (or, under certain circumstances, other securities or assets of the Company) having a value equal to two times the amount paid to exercise the Right. However, the Rights are subject to redemption or exchange by the Company prior to their exercise as described below. A Distribution Date would occur upon the earlier of (i) ten days after the public announcement that a person or group has acquired, or obtained the right to acquire, beneficial ownership of the Company’s common stock or other voting stock (including Synthetic Long Positions as defined in the Plan) having 10% or more of the total voting power of the Company’s common stock and other voting stock and (ii) ten days after the commencement or announcement by a person or group of an intention to make a tender or exchange offer that would result in that person acquiring, or obtaining the right to acquire, beneficial ownership of the Company’s common stock or other voting stock having 10% or more of the total voting power of the Company’s common stock and other voting stock. In certain situations after a person or group has acquired beneficial ownership of 10% or more of the total voting power of the Company’s stock as described above, each holder of a Right will have the right to exercise its Rights to receive, upon exercise of the right, common stock of the acquiring company having a value equal to two times the amount paid to exercise the right. These situations would arise if the Company is acquired in a merger or other business combination or if 50% or more of the Company’s assets or earning power are sold or transferred. At any time prior to the end of the business day on the tenth day following the Distribution Date, the Company may redeem the Rights in whole, but not in part, at a price of $0.005 per Right, payable in cash or stock. A decision to redeem the Rights requires the vote of 75% of the Company’s full Board of Directors. Also, at any time following the Distribution Date, 75% of the Company’s full Board of Directors may vote to exchange the Rights, in whole or in part, at an exchange rate of one share of common stock, or other property deemed to have the same value, per Right, subject to certain adjustments. Upon exercise of the Rights, the Company may need additional regulatory approvals to satisfy the requirements of the Rights Agreement. The Rights will expire on July 31, 2018, unless earlier than that date, they are exchanged or redeemed or the Plan is amended to extend the expiration date. Stock Option and Stock Award Plans The Company has various stock option and stock award plans which provide or provided for the issuance of one or more of the following to key employees: incentive stock options, nonqualified stock options, SARs, restricted stock, performance units or performance shares. Stock options and SARs under all plans have exercise prices equal to the average market price of Company common stock on the date of grant, and generally no option or SAR is exercisable less than one year or more than ten years after the date of each grant. 92 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Transactions involving option shares for all plans are summarized as follows: Number of Shares Subject to Option Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (In thousands) Outstanding at September 30, 2009 . . . . . . . . . . . . . . . . . . . . .

Restricted Share Awards Restricted stock is subject to restrictions on vesting and transferability. Restricted stock awards entitle the participants to full dividend and voting rights. The market value of restricted stock on the date of the award is recorded as compensation expense over the vesting period. Certificates for shares of restricted stock awarded under the Company’s stock option and stock award plans are held by the Company during the periods in which the restrictions on vesting are effective.

(2) Current Portion of Long-Term Debt at September 30, 2010 consists of $200 million of 7.50% medium-term notes that mature in November 2010. In April 2009, the Company issued $250.0 million of 8.75% notes due in May 2019. After deducting underwriting discounts and commissions, the net proceeds to the Company amounted to $247.8 million. These notes were registered under the Securities Act of 1933. The holders of the notes may require the Company to repurchase their notes at a price equal to 101% of the principal amount in the event of both a change in control and a ratings downgrade to a rating below investment grade. The proceeds of this debt issuance were used for general corporate purposes, including to replenish cash that was used to pay the $100 million due at the maturity of the Company’s 6.0% medium-term notes on March 1, 2009. The Company has $300.0 million of 6.50% notes that mature in April 2018. The holders of the notes may require the Company to repurchase their notes at a price equal to 101% of the principal amount in the event of both a change in control and a ratings downgrade to a rating below investment grade. As of September 30, 2010, the aggregate principal amounts of long-term debt maturing during the next five years and thereafter are as follows: $200.0 million in 2011, $150.0 million in 2012, $250.0 million in 2013, zero in 2014, zero in 2015 and $649.0 million thereafter. Short-Term Borrowings The Company historically has obtained short-term funds either through bank loans or the issuance of commercial paper. As for the former, the Company maintains a number of individual uncommitted or discretionary lines of credit with certain financial institutions for general corporate purposes. Borrowings under these lines of credit are made at competitive market rates. These credit lines, which aggregate to $405.0 million, are revocable at the option of the financial institutions and are reviewed on an annual basis. The Company anticipates that these lines of credit will continue to be renewed, or substantially replaced by similar lines. The total amount available to be issued under the Company’s commercial paper program is $300.0 million. The commercial paper program is backed by a syndicated committed credit facility totaling $300.0 million, which commitment extends through September 30, 2013. At September 30, 2010 and 2009, the Company did not have any outstanding short-term notes payable to banks or commercial paper. 95 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Debt Restrictions Under the Company’s committed credit facility, the Company has agreed that its debt to capitalization ratio will not exceed .65 at the last day of any fiscal quarter through September 30, 2013. At September 30, 2010, the Company’s debt to capitalization ratio (as calculated under the facility) was .42. The constraints specified in the committed credit facility would permit an additional $1.99 billion in short-term and/or long-term debt to be outstanding (further limited by the indenture covenants discussed below) before the Company’s debt to capitalization ratio would exceed .65. If a downgrade in any of the Company’s credit ratings were to occur, access to the commercial paper markets might not be possible. However, the Company expects that it could borrow under its committed credit facility, uncommitted bank lines of credit or rely upon other liquidity sources, including cash provided by operations. Under the Company’s existing indenture covenants, at September 30, 2010, the Company would have been permitted to issue up to a maximum of $1.3 billion in additional long-term unsecured indebtedness at then current market interest rates in addition to being able to issue new indebtedness to replace maturing debt. The Company’s present liquidity position is believed to be adequate to satisfy known demands. However, if the Company were to experience a significant loss in the future (for example, as a result of an impairment of oil and gas properties), it is possible, depending on factors including the magnitude of the loss, that these indenture covenants would restrict the Company’s ability to issue additional long-term unsecured indebtedness for a period of up to nine calendar months, beginning with the fourth calendar month following the loss. This would not at any time preclude the Company from issuing new indebtedness to replace maturing debt. The Company’s 1974 indenture pursuant to which $99.0 million (or 7.9%) of the Company’s long-term debt (as of September 30, 2010) was issued, contains a cross-default provision whereby the failure by the Company to perform certain obligations under other borrowing arrangements could trigger an obligation to repay the debt outstanding under the indenture. In particular, a repayment obligation could be triggered if the Company fails (i) to pay any scheduled principal or interest on any debt under any other indenture or agreement, or (ii) to perform any other term in any other such indenture or agreement, and the effect of the failure causes, or would permit the holders of the debt to cause, the debt under such indenture or agreement to become due prior to its stated maturity, unless cured or waived. The Company’s $300.0 million committed credit facility also contains a cross-default provision whereby the failure by the Company or its significant subsidiaries to make payments under other borrowing arrangements, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the committed credit facility. In particular, a repayment obligation could be triggered if (i) the Company or any of its significant subsidiaries fails to make a payment when due of any principal or interest on any other indebtedness aggregating $40.0 million or more, or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $40.0 million or more to cause, such indebtedness to become due prior to its stated maturity. As of September 30, 2010, the Company had no debt outstanding under the committed credit facility. Note F — Fair Value Measurements The FASB authoritative guidance regarding fair value measurements establishes a fair-value hierarchy and prioritizes the inputs used in valuation techniques that measure fair value. Those inputs are prioritized into three levels. Level 1 inputs are unadjusted quoted prices in active markets for assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly at the measurement date. Level 3 inputs are unobservable inputs for the asset or liability at the measurement date. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. 96 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The following table sets forth, by level within the fair value hierarchy, the Company’s financial assets and liabilities (as applicable) that were accounted for at fair value on a recurring basis as of September 30, 2010 and 2009. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. In January 2010, the FASB issued amended authoritative guidance respecting disclosures related to fair value measurements. The amended guidance requires disclosure of financial instruments and liabilities by class of assets and liabilities (not major category of assets and liabilities). In addition, this amended guidance also requires enhanced disclosures about the valuation techniques and inputs used to measure fair value and disclosures of transfers in and out of Level 1 or 2. During the quarter ended March 31, 2010, the Company adopted this amended guidance.

Hedging collateral deposits of $10.1 million (at September 30, 2010) and $0.8 million (at September 30, 2009), which are associated with these futures contracts have been reported in Level 1 as well. The derivative financial instruments reported in Level 2, at September 30, 2010 and 2009, consist of natural gas swap agreements used in the Company’s Exploration and Production and Energy Marketing segments. The fair value of these swap agreements is based on an internal, discounted cash flow model that uses observable inputs (i.e. LIBOR based discount rates and basis differential information, if applicable, at active natural gas trading markets). At September 30, 2010 and 2009, the derivative financial instruments reported in Level 3 consist of all of the Exploration and Production segment’s crude oil swap agreements. Hedging collateral deposits of $1.0 million associated with these oil swap agreements have been reported in Level 1 at September 30, 2010. The fair value of the crude oil swap agreements is based on an internal, discounted cash flow model that uses both observable (i.e. LIBOR based discount rates) and unobservable inputs (i.e. basis differential information of crude oil trading markets with low trading volume). Based on an assessment of the counterparties’ credit risk, the fair market value of the price swap agreements reported as Level 2 and Level 3 assets have been reduced by $1.0 million and $0.9 million at September 30, 2010 and September 30, 2009, respectively. The fair market value of the price swap agreements reported as Level 2 and Level 3 liabilities at September 30, 2010 have been reduced by $0.3 million and the price swap agreements reported as Level 2 liabilities at September 30, 2009 have been reduced by less than $0.1 million based on an assessment of the Company’s credit risk. These credit reserves were determined by applying default probabilities to the anticipated cash flows that the Company is either expecting from its counterparties or expecting to pay to its counterparties. The tables listed below provide reconciliations of the beginning and ending net balances for assets and liabilities measured at fair value and classified as Level 3. For the 12 months ended September 30, 2010, no transfers in or out of Level 1 or Level 2 occurred. 98 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Fair Value Measurements Using Unobservable Inputs (Level 3) Total Gains/Losses— Realized and Unrealized October 1, 2009 Included in Earnings Included in Other Comprehensive Income (Loss) Transfer In/(Out) of Level 3 September 30, 2010 (Dollars in thousands) Derivative Financial Instruments(2) . . . . $26,969 $(9,372)(1) $(34,080) $— $(16,483) (1) Amounts are reported in Operating Revenues in the Consolidated Statement of Income for the year ended September 30, 2010.

(2) Derivative Financial Instruments are shown on a net basis. (3) These transfers occurred because the Company was able to obtain and utilize forward-looking, observable basis differential information for its hedges on southern California natural gas production. Note G — Financial Instruments Long-Term Debt The fair market value of the Company’s debt, as presented in the table below, was determined using a discounted cash flow model, which incorporates the Company’s credit ratings and current market conditions in determining the yield, and subsequently, the fair market value of the debt. Based on these criteria, the fair market value of long-term debt, including current portion, was as follows: 2010 Carrying Amount 2010 Fair Value 2009 Carrying Amount 2009 Fair Value At September 30 (Thousands) Long-Term Debt . . . . . . . . . . . . . . . . . $1,249,000 $1,423,349 $1,249,000 $1,347,368 The fair value amounts are not intended to reflect principal amounts that the Company will ultimately be required to pay. Carrying amounts for other financial instruments recorded on the Company’s Consolidated Balance Sheets approximate fair value. The increase in the fair value of the Company’s debt is attributable to a decrease in the estimated rate at which the Company could issue debt at September 30, 2010 relative to September 30, 2009. 99 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Other Investments Investments in life insurance are stated at their cash surrender values or net present value as discussed below. Investments in an equity mutual fund and the stock of an insurance company (marketable equity securities), as discussed below, are stated at fair value based on quoted market prices. Other investments include cash surrender values of insurance contracts (net present value in the case of split-dollar collateral assignment arrangements) and marketable equity securities. The values of the insurance contracts amounted to $55.4 million and $54.2 million at September 30, 2010 and 2009, respectively. The fair value of the equity mutual fund was $17.3 million and $15.8 million at September 30, 2010 and 2009, respectively. The unrealized gain on the equity mutual fund at September 30, 2010 was negligible as the fair market value was approximately equal to the cost basis. The gross unrealized loss on this equity mutual fund was $1.0 million at September 30, 2009. The fair value of the stock of an insurance company was $5.0 million and $8.3 million at September 30, 2010 and 2009, respectively. The gross unrealized gain on this stock was $2.6 million and $5.9 million at September 30, 2010 and 2009, respectively. The insurance contracts and marketable equity securities are primarily informal funding mechanisms for various benefit obligations the Company has to certain employees. Derivative Financial Instruments The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is commodity price risk in the Exploration and Production and Energy Marketing segments. The Company enters into futures contracts and over-the-counter swap agreements for natural gas and crude oil to manage the price risk associated with forecasted sales of gas and oil. The Company also enters into futures contracts and swaps to manage the risk associated with forecasted gas purchases, storage of gas, withdrawal of gas from storage to meet customer demand, and the potential decline in the value of gas held in storage. The duration of the Company’s hedges do not typically exceed 3 years. The Company has presented its net derivative assets and liabilities on its Consolidated Balance Sheet at September 30, 2010 and September 30, 2009 as shown in the table below.

Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. As of September 30, 2010, the Company’s Exploration and Production segment had the following commodity derivative contracts (swaps) outstanding to hedge forecasted sales (where the Company uses short positions (i.e. positions that pay-off in the event of commodity price decline) to mitigate the risk of decreasing revenues and earnings): Commodity Natural Gas Crude Oil Units 37.5 Bcf (all short positions) 2,688,000 Bbls (all short positions) As of September 30, 2010, the Company’s Energy Marketing segment had the following commodity derivative contracts (futures contracts and swaps) outstanding to hedge forecasted sales (where the Company uses short positions to mitigate the risk associated with natural gas price decreases and its impact on decreasing revenues and earnings) and purchases (where the Company uses long positions (i.e. positions that pay-off in the event of commodity price increases) to mitigate the risk of increasing natural gas prices, which would lead to increased purchased gas expense and decreased earnings): Commodity Natural Gas Units 6.2 Bcf (6.1 Bcf short positions (forecasted storage withdrawals) and 0.1 Bcf long positions (forecasted storage injections)) As of September 30, 2010, the Company’s Exploration and Production segment had $49.1 million ($28.9 million after tax) of gains included in the accumulated other comprehensive income (loss) balance. It is expected that $33.3 million ($19.6 million after tax) of these gains will be reclassified into the Consolidated Statement of Income within the next 12 months as the expected sales of the underlying commodities occur. See Note A, under Accumulated Other Comprehensive Income (Loss), for the after-tax gain pertaining to derivative financial instruments (Net Unrealized Gain (Loss) on Derivative Financial Instruments in Note A includes the Exploration and Production and Energy Marketing segments). As of September 30, 2010, the Company’s Energy Marketing segment had $6.5 million ($4.0 million after tax) of gains included in the accumulated other comprehensive income (loss) balance. It is expected that all of these gains will be reclassified into the Consolidated Statement of Income within the next 12 months as the sales and purchases of the underlying commodities occur. See Note A, under Accumulated Other Comprehensive Income (Loss), for the after-tax gain pertaining to derivative financial instruments (Net Unrealized Gain (Loss) 101 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) on Derivative Financial Instruments in Note A includes the Exploration and Production and Energy Marketing segments).

As such there is no mention of these positions in the preceding sections of this footnote. Fair value hedges The Company’s Energy Marketing segment utilizes fair value hedges to mitigate risk associated with fixed price sales commitments, fixed price purchase commitments, and the decline in the value of natural gas held in storage. With respect to fixed price sales commitments, the Company enters into long positions to mitigate the risk of price increases for natural gas supplies that could occur after the Company enters into fixed price sales agreements with its customers. With respect to fixed price purchase commitments, the Company enters into short positions to mitigate the risk of price decreases that could occur after the Company locks into fixed price purchase deals with its suppliers. With respect to storage hedges, the Company enters into short positions to mitigate the risk of price decreases that could result in a lower of cost or market writedown of the value of natural gas in storage that is recorded in the Company’s financial statements. As of September 30, 2010, the Company’s Energy Marketing segment had fair value hedges covering approximately 15.3 Bcf (14.2 Bcf of fixed price sales commitments (all long positions), 0.9 Bcf of fixed price purchase commitments (all short positions), and 0.2 Bcf of storage hedges (all short positions)). For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk completely offset each other in current earnings, as shown below.

Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of the Company’s counterparties are financial institutions and energy traders. The Company has over-the-counter swap positions with eleven counterparties of which ten of the eleven counterparties are in a net gain position. On average, the Company had $6.5 million of credit exposure per counterparty in a gain position at September 30, 2010. The maximum credit exposure per counterparty at September 30, 2010 was $11.9 million. BP Energy Company (an affiliate of BP Corporation North America, Inc.) was one of the ten counterparties in a gain position. At September 30, 2010, the Company had an $11.3 million receivable with BP Energy Company. The Company considered the credit quality of BP Energy Company (as it does with all of its counterparties) in determining hedge effectiveness and believes the hedges remain effective. The Company had not received any collateral from these counterparties at September 30, 2010 since the Company’s gain position on such derivative financial instruments had not exceeded the established thresholds at which the counterparties would be required to post collateral. As of September 30, 2010, nine of the eleven counterparties to the Company’s outstanding derivative instrument contracts (specifically the over-the-counter swaps) had a common credit-risk related contingency feature. In the event the Company’s credit rating increases or falls below a certain threshold (the lower of the S&P or Moody’s Debt Rating), the available credit extended to the Company would either increase or decrease. A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt instruments). If the Company’s outstanding derivative instrument contracts were in a liability position and the Company’s credit rating declined, then additional hedging collateral deposits would be required. At September 30, 2010, the fair market value of the derivative financial instrument assets with a credit-risk related contingency feature was $42.1 million according to the Company’s internal model (discussed in Note F — Fair Value Measurements). At September 30, 2010, the fair market value of the derivative financial instrument liability with a credit-risk related contingency feature was $14.3 million according to the Company’s internal model (discussed in Note F — Fair Value Measurements). For its over-the-counter crude oil swap agreements, which are in a liability position, the Company was required to post $1.0 million in hedging collateral deposits at September 30, 2010. This is discussed in Note A under Hedging Collateral Deposits. 103 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) For its exchange traded futures contracts which are in a liability position, the Company had posted $10.1 million in hedging collateral as of September 30, 2010. As these are exchange traded futures contracts, there are no specific credit-risk related contingency features. The Company posts hedging collateral based on open positions and margin requirements it has with its counterparties. The Company’s requirement to post hedging collateral deposits is based on the fair value determined by the Company’s counterparties, which may differ from the Company’s assessment of fair value. Hedging collateral deposits may also include closed derivative positions in which the broker has not cleared the cash from the account to offset the derivative liability. The Company records liabilities related to closed derivative positions in Other Accruals and Current Liabilities on the Consolidated Balance Sheet. These liabilities are relieved when the broker clears the cash from the hedging collateral deposit account. This is discussed in Note A under Hedging Collateral Deposits. Note H — Retirement Plan and Other Post-Retirement Benefits The Company has a tax-qualified, noncontributory, defined-benefit retirement plan (Retirement Plan) that covers a majority of the full-time employees of the Company. The Retirement Plan covers certain non- collectively bargained employees hired before July 1, 2003 and certain collectively bargained employees hired before November 1, 2003. Certain non-collectively bargained employees hired after June 30, 2003 and certain collectively bargained employees hired after October 31, 2003 are eligible for a Retirement Savings Account benefit provided under the Company’s defined contribution Tax-Deferred Savings Plans. Costs associated with the Retirement Savings Account were $0.6 million, $0.4 million and $0.2 million for the years ended September 30, 2010, 2009 and 2008, respectively. Costs associated with the Company’s contributions to the Tax-Deferred Savings Plans, exclusive of the costs associated with the Retirement Savings Account, were $4.2 million, $4.1 million, and $4.0 million for the years ended September 30, 2010, 2009 and 2008, respectively. The Company provides health care and life insurance benefits (other post-retirement benefits) for a majority of its retired employees. The other post-retirement benefits cover certain non-collectively bargained employees hired before January 1, 2003 and certain collectively bargained employees hired before October 31, 2003. The Company’s policy is to fund the Retirement Plan with at least an amount necessary to satisfy the minimum funding requirements of applicable laws and regulations and not more than the maximum amount deductible for federal income tax purposes. The Company has established VEBA trusts for its other post- retirement benefits. Contributions to the VEBA trusts are tax deductible, subject to limitations contained in the Internal Revenue Code and regulations and are made to fund employees’ other post-retirement benefits, as well as benefits as they are paid to current retirees. In addition, the Company has established 401(h) accounts for its other post-retirement benefits. They are separate accounts within the Retirement Plan trust used to pay retiree medical benefits for the associated participants in the Retirement Plan. Although these accounts are in the Retirement Plan trust, for funding status purposes as shown below, the 401(h) accounts are included in Fair Value of Assets under Other Post-Retirement Benefits. Contributions are tax-deductible when made, subject to limitations contained in the Internal Revenue Code and regulations. Retirement Plan, VEBA trust and 401(h) account assets primarily consist of equity and fixed income investments or units in commingled funds or money market funds. The expected return on plan assets, a component of net periodic benefit cost shown in the tables below, is applied to the market-related value of plan assets. The market-related value of plan assets is the market value as of the measurement date adjusted for variances between actual returns and expected returns (from previous years) that have not been reflected in net periodic benefit costs.

This decreased the benefit obligation. (2) Distribution Corporation’s New York jurisdiction calculates the amortization of the actuarial loss on a vintage year basis over 10 years, as mandated by the NYPSC. All the other subsidiaries of the Company utilize the corridor approach. The Net Periodic Benefit Cost in the table above includes the effects of regulation. The Company recovers pension and other post-retirement benefit costs in its Utility and Pipeline and Storage segments in accordance with the applicable regulatory commission authorizations. Certain of those commission authorizations established tracking mechanisms which allow the Company to record the difference between the amount of pension and other post-retirement benefit costs recoverable in rates and the amounts of such costs as determined under the existing authoritative guidance as either a regulatory asset or liability, as appropriate. Any activity under the tracking mechanisms (including the amortization of pension and other post-retirement regulatory assets and liabilities) is reflected in the Net Amortization and Deferral for Regulatory Purposes line item above. As noted above, through 2008, the Company used June 30th as the measurement date for financial reporting purposes. In 2009, in accordance with the current authoritative guidance for defined benefit pension and other postretirement plans, the Company began measuring the Plan’s assets and liabilities for its pension and other post-retirement benefit plans as of September 30th, its fiscal year end. In making this change and as 106 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) permitted by the current authoritative guidance, the Company recorded fifteen months of pension and post- retirement benefits expense during the fiscal year ended September 30, 2009. As allowed by the authoritative guidance, these costs were calculated using June 30, 2008 measurement date data. Three of those months pertained to the period of July 1, 2008 to September 30, 2008. The pension and other post-retirement benefit costs for that period amounted to $3.8 million and were recorded by the Company during the year ended September 30, 2009 as a $3.4 million increase to Other Regulatory Assets in the Company’s Utility and Pipeline and Storage segments and a $0.4 million ($0.2 million after tax) adjustment to earnings reinvested in the business. In addition, for the Company’s non-qualified benefit plan, benefit costs of $1.3 million were recorded by the Company during the year ended September 30, 2009 as a $0.4 million increase to Other Regulatory Assets in the Company’s Utility segment and a $0.9 million ($0.6 million after tax) adjustment to earnings reinvested in the business. The cumulative amounts recognized in accumulated other comprehensive income (loss), regulatory assets, and regulatory liabilities through fiscal 2010, the changes in such amounts during 2010, as well as the amounts expected to be recognized in net periodic benefit cost in fiscal 2011 are presented in the table below: Retirement Plan Other Post-Retirement Benefits (Thousands) Non-Qualified Benefit Plans Amounts Recognized in Accumulated Other Comprehensive Income (Loss), Regulatory Assets and Regulatory Liabilities(1) Net Actuarial Loss . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $(385,522) $(157,700) (1,487) Transition Obligation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8,807 Prior Service (Cost) Credit . . . . . . . . . . . . . . . . . . . . . . . . — (3,925) $(33,949) — — Net Amount Recognized . . . . . . . . . . . . . . . . . . . . . . . . . . $(389,447) $(150,380) $(33,949) Changes to Accumulated Other Comprehensive Income (Loss), Regulatory Assets and Regulatory Liabilities Recognized During Fiscal 2010(1) Increase in Net Actuarial Gain/(Loss) . . . . . . . . . . . . . . . . . $ (60,907) $ 33,660 540 Reduction in Transition Obligation . . . . . . . . . . . . . . . . . .

In order to adjust the funded status of its pension (tax-qualified and non-qualified) and other post- retirement benefit plans at September 30, 2010, the Company recorded an $11.8 million increase to Other Regulatory Assets in the Company’s Utility and Pipeline and Storage segments and a $25.2 million (pre-tax) increase to Accumulated Other Comprehensive Loss. 107 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The effect of the discount rate change for the Retirement Plan in 2010 was to increase the projected benefit obligation of the Retirement Plan by $75.1 million. In 2010, other actuarial experience increased the projected benefit obligation for the Retirement Plan by $10.8 million. The effect of the discount rate change for the Retirement Plan in 2009 was to increase the projected benefit obligation of the Retirement Plan by $102.6 million. The effect of the discount rate change for the Retirement Plan in 2008 was to decrease the projected benefit obligation of the Retirement Plan by $38.6 million. The Company made cash contributions totaling $22.2 million to the Retirement Plan during the year ended September 30, 2010. The Company expects that the annual contribution to the Retirement Plan in 2011 will be in the range of $40.0 million to $45.0 million. Changes in the discount rate, other actuarial assumptions, and asset performance could ultimately cause the Company to fund larger amounts to the Retirement Plan in 2011 in order to be in compliance with the Pension Protection Act of 2006. The following benefit payments, which reflect expected future service, are expected to be paid during the next five years and the five years thereafter: $52.1 million in 2011; $52.9 million in 2012; $53.8 million in 2013; $54.9 million in 2014; $56.3 million in 2015; and $305.4 million in the five years thereafter. In addition to the Retirement Plan discussed above, the Company also has Non-Qualified benefit plans that cover a group of management employees designated by the Chief Executive Officer of the Company. These plans provide for defined benefit payments upon retirement of the management employee, or to the spouse upon death of the management employee. The net periodic benefit cost associated with these plans were $7.4 million, $5.4 million and $5.2 million in 2010, 2009 and 2008, respectively. The accumulated benefit obligations for the plans were $41.8 million and $37.4 million at September 30, 2010 and 2009, respectively. The projected benefit obligations for the plans were $73.9 million and $64.6 million at September 30, 2010 and 2009, respectively. The actuarial valuations for the plans were determined based on a discount rate of 4.25%, 5.25% and 6.75% as of September 30, 2010, 2009 and 2008, respectively and a weighted average rate of compensation increase of 8.0%, 8.25% and 8.75% as of September 30, 2010, 2009 and 2008, respectively. The effect of the discount rate change in 2010 was to increase the other post-retirement benefit obligation by $39.4 million. Other actuarial experience decreased the other post-retirement benefit obligation in 2010 by $43.1 million, primarily attributable to updated pharmaceutical drug rebate experience as well as updated claim costs assumptions based on experience. The effect of the discount rate change in 2009 was to increase the other post-retirement benefit obligation by $60.9 million. Effective October 1, 2009, the Medicare Part B reimbursement trend, prescription drug trend and medical trend assumptions were changed. The effect of these assumption changes was to increase the other post-retirement benefit obligation by $27.0 million. Other actuarial experience decreased the other post- retirement benefit obligation in 2009 by $32.1 million. The effect of the discount rate change in 2008 was to decrease the other post-retirement benefit obligation by $26.3 million. Effective July 1, 2008, the Medicare Part B reimbursement trend, prescription drug trend and medical trend assumptions were changed. The effect of these assumption changes was to increase the other post- retirement benefit obligation by $20.0 million. Other actuarial experience decreased the other post-retirement benefit obligation in 2008 by $8.1 million. On December 8, 2003, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the Act) was signed into law. This Act introduced a prescription drug benefit under Medicare (Medicare Part D), as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. Since the Company is assumed to continue to provide a prescription drug benefit to retirees in the point of service and indemnity plans that is at least actuarially equivalent to Medicare Part D, the impact of the Act was reflected as of December 8, 2003. 108 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The estimated gross other post-retirement benefit payments and gross amount of Medicare Part D prescription drug subsidy receipts are as follows: Benefit Payments Subsidy Receipts 2011 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2012 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2013 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2014 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2015 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2016 through 2020 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 25,375,000 $ 26,795,000 $ 28,116,000 $ 29,520,000 $ 31,002,000 $175,195,000 $ (2,001,000) $ (2,275,000) $ (2,575,000) $ (2,871,000) $ (3,169,000) $(20,370,000) 2010 2009 2008 Rate of Increase for Pre Age 65 Participants . . . . . . . . . . . . . . . . . . . . . 7.82%(1) 8.0%(1) Rate of Increase for Post Age 65 Participants . . . . . . . . . . . . . . . . . . . . 6.95%(1) 7.0%(1) Annual Rate of Increase in the Per Capita Cost of Covered Prescription 9.0%(2) 7.0%(2) Drug Benefits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8.69%(1) 9.0%(1) 10.0%(2) Annual Rate of Increase in the Per Capita Medicare Part B Reimbursement . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6.95%(1) 7.0%(1) 7.0%(2) Annual Rate of Increase in the Per Capita Medicare Part D Subsidy . . . 7.60%(1) 7.9%(1) 10.0%(2) (1) It was assumed that this rate would gradually decline to 4.5% by 2028. (2) It was assumed that this rate would gradually decline to 5.0% by 2018. The health care cost trend rate assumptions used to calculate the per capita cost of covered medical care benefits have a significant effect on the amounts reported. If the health care cost trend rates were increased by 1% in each year, the other post-retirement benefit obligation as of October 1, 2010 would increase by $57.6 million. This 1% change would also have increased the aggregate of the service and interest cost components of net periodic post-retirement benefit cost for 2010 by $4.0 million. If the health care cost trend rates were decreased by 1% in each year, the other post-retirement benefit obligation as of October 1, 2010 would decrease by $48.6 million. This 1% change would also have decreased the aggregate of the service and interest cost components of net periodic post-retirement benefit cost for 2010 by $3.3 million. The Company made cash contributions totaling $25.5 million to its VEBA trusts and 401(h) accounts during the year ended September 30, 2010. In addition, the Company made direct payments of $0.2 million to retirees not covered by the VEBA trusts and 401(h) accounts during the year ended September 30, 2010. The Company expects that the annual contribution to its VEBA trusts and 401(h) accounts in 2011 will be in the range of $25.0 million to $30.0 million. Investment Valuation The Retirement Plan assets and other post-retirement benefit assets are valued under the current fair value framework. See Note F “Fair Value Measurements” for further discussion regarding the definition and levels of fair value hierarchy established by the authoritative guidance. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Below is a listing of the major categories of plan assets held as of September 30, 2010, as well as the associated level within the fair value hierarchy in which the fair value 109 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) measurements in their entirety fall (based on the lowest level input that is significant to the fair value measurement in its entirety).

These are valued using quoted market values as of the end of the year. Level 2 equities consist primarily of investments in collective trusts. The fair value of such trusts is derived from the fair value of the underlying investments. In addition, there are Level 2 equities that consist of convertible securities, for which quoted market values are unavailable or are not used because the associated trading volumes are lower, that are valued using observable market data. Level 3 equities consist of investments in convertible securities where there are no readily obtainable market values. These investments are valued using unobservable market data. Fixed Income: Level 1 fixed income securities consist of exchange-traded bond funds and are valued using quoted market values as of the end of the year. Level 2 fixed income securities consist primarily of investments in collective trusts, corporate bonds and other investments (typically guaranteed investment contracts, collateralized mortgage obligations, asset backed securities, etc). The collective trusts are carried at the stated unit value of funds, which are derived from the fair value of the underlying investments. The corporate bonds and other investments are valued using observable market data. Level 3 fixed income securities typically consist of collateralized mortgage obligations, asset backed securities, and corporate/ government bonds that are not actively traded. At September 30, 2010, there are no such investments. Real Estate: Level 3 real estate investments consist primarily of commercial and residential properties that are valued at the Plan’s proportionate interest in the total current value of the underlying net assets of these investments. This fair value is determined using unobservable market data. Limited Partnerships: Level 3 limited partnerships consist of cash held in the partnerships and private equity holdings. The Plan’s interest in these partnerships is valued based on the fair value as determined by the general partner or board of directors. The fair value of the private equity holdings is determined using unobservable market data. Cash and Cash Equivalents: The cash and cash equivalents in Level 2 consists of collective trusts that invest in various cash and money market investments as well as treasury bills, notes, and bonds. In addition, cash held in checking/savings accounts and commercial paper are included as well. VEBA Investments: Collective Trust Funds: The fair value of collective trust funds classified as Level 2 are derived from the fair value of the underlying investments in equities (primarily publicly traded stocks). Cash and Cash Equivalents: The cash equivalents reported in Level 2 consists of an institutional fund that invests in high quality, short-term municipal instruments. This fund is valued at amortized cost, which the investment advisor has determined approximates fair value. Real Estate: Level 3 real estate investments consist primarily of commercial and residential properties that are valued at the VEBA’s proportionate interest in the total current value of the underlying net assets of these investments. This fair value is determined using unobservable market data. The preceding methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following tables provide a reconciliation of the beginning and ending balances of the Retirement Plan and other post-retirement benefit assets measured at fair value on a recurring basis where the determination of 112 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) fair value includes significant unobservable inputs (Level 3). Note: For the year-ended September 30, 2010, there were no significant transfers in or out of Level 1 or Level 2.

The return assumption reflects the anticipated long-term rate of return on the plan’s current and future assets. The Company utilizes historical investment data, projected capital market conditions, and the plan’s target asset class and investment manager allocations to set the assumption regarding the expected return on plan assets. The long-term investment objective of the Retirement Plan trust, the VEBA trusts and the 401(h) accounts is to achieve the target total return in accordance with the Company’s risk tolerance. Assets are diversified utilizing a mix of equities, fixed income and other securities (including real estate). Risk tolerance is established through consideration of plan liabilities, plan funded status and corporate financial condition. The assets of the Retirement Plan trusts, VEBA trusts and the 401(h) accounts have no significant concentrations of risk in any one country (other than the United States), industry or entity. Investment managers are retained to manage separate pools of assets. Comparative market and peer group performance of individual managers and the total fund are monitored on a regular basis, and reviewed by the Company’s Retirement Committee on at least a quarterly basis. The discount rate which is used to present value the future benefit payment obligations of the Retirement Plan and the Company’s other post-retirement benefits is 4.75% as of September 30, 2010. The discount rate which is used to present value the future benefit payment obligations of the Non-Qualified benefit plans is 4.25% as of September 30, 2010. The Company utilizes a yield curve model to determine the discount rate. The yield curve is a spot rate yield curve that provides a zero-coupon interest rate for each year into the future. Each year’s anticipated benefit payments are discounted at the associated spot interest rate back to the measurement date. The discount rate is then determined based on the spot interest rate that results in the same present value when applied to the same anticipated benefit payments. Note I — Commitments and Contingencies Environmental Matters The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment. The Company has established procedures for the ongoing evaluation of its operations, to identify potential environmental exposures and to comply with regulatory policies and procedures. It is the Company’s policy to accrue estimated environmental clean-up costs (investigation and remediation) when such amounts can reasonably be estimated and it is probable that the Company will be required to incur such costs. At September 30, 2010, the Company has estimated its remaining clean-up costs related to former manufactured gas plant sites and third party waste disposal sites will be in the range of $17.3 million to $21.5 million. The minimum estimated liability of $17.3 million has been recorded on the Consolidated Balance Sheet at September 30, 2010. The Company expects to recover its environmental clean-up costs through rate recovery. Other than as discussed below, the Company is currently not aware of any material exposure to environmental liabilities. However, changes in environmental regulations, new information or other factors could adversely impact the Company. 114 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) (i) Former Manufactured Gas Plant Sites The Company has incurred investigation and/or clean-up costs at several former manufactured gas plant sites in New York and Pennsylvania. The Company continues to be responsible for future ongoing monitoring and long-term maintenance at two sites. The Company has agreed with the NYDEC to remediate another former manufactured gas plant site located in New York. The Company has received approval from the NYDEC of a Remedial Design work plan for this site and has recorded an estimated minimum liability for remediation of this site of $14.7 million. (ii) Other In June 2007, the NYDEC notified the Company, as well as a number of other companies, of their potential liability with respect to a remedial action at a waste disposal site in New York. The notification identified the Company as one of approximately 500 other companies considered to be PRPs related to this site and requested that the remedy the NYDEC proposed in a Record of Decision issued in March 2006 be performed. The estimated clean-up costs under the remedy selected by the NYDEC are estimated to be approximately $13.0 million if implemented. The Company participates in an organized group with other PRPs who are addressing this site. In November 2010, the NYDEC notified the Company of its potential liability with respect to a remedial action at former industrial sites in New York. Along with the Company, notifications were sent to the City of Buffalo and the New York State Thruway Authority. Estimated clean-up costs associated with these sites have not been completed and the Company cannot estimate its liability, if any, regarding these sites at this time. Other The Company, in its Utility segment, Energy Marketing segment, and All Other category, has entered into contractual commitments in the ordinary course of business, including commitments to purchase gas, transportation, and storage service to meet customer gas supply needs. Substantially all of these contracts expire within the next five years. The future gas purchase, transportation and storage contract commitments during the next five years and thereafter are as follows: $380.1 million in 2011, $86.3 million in 2012, $51.6 million in 2013, $34.7 million in 2014, $19.8 million in 2015 and $14.5 million thereafter. Gas prices within the gas purchase contracts are variable based on NYMEX prices adjusted for basis. In the Utility segment, these costs are subject to state commission review, and are being recovered in customer rates. Management believes that, to the extent any stranded pipeline costs are generated by the unbundling of services in the Utility segment’s service territory, such costs will be recoverable from customers. The Company has entered into leases for the use of buildings, vehicles, construction tools, meters, computer equipment and other items. These leases are accounted for as operating leases. The future lease commitments during the next five years and thereafter are as follows: $5.1 million in 2011, $4.6 million in 2012, $3.5 million in 2013, $3.2 million in 2014, $2.8 million in 2015, and $8.2 million thereafter. The Company is involved in other litigation arising in the normal course of business. In addition to the regulatory matters discussed in Note C — Regulatory Matters, the Company is involved in other regulatory matters arising in the normal course of business. These other litigation and regulatory matters may include, for example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations and other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas cost issues, among other things. While these normal-course matters could have a material effect on earnings and cash flows in the period in which they are resolved, they are not expected to change materially the Company’s present liquidity position, nor are they expected to have a material adverse effect on the financial condition of the Company. 115 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Note J — Discontinued Operations On September 1, 2010, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana. Those operations consisted of short distance landfill gas pipeline companies engaged in the purchase, sale and transportation of landfill gas. The Company’s landfill gas operations were maintained under the Company’s wholly-owned subsidiary, Horizon LFG. The Company received approximately $38.0 million of proceeds from the sale. The sale resulted in the recognition of a gain of approximately $6.3 million, net of tax, during the fourth quarter of 2010. The decision to sell was based on progressing the Company’s strategy of divesting its smaller, non-core assets in order to focus on its core businesses, including the development of the Marcellus Shale and the construction of key pipeline infrastructure projects throughout the Appalachian region. As a result of the decision to sell the landfill gas operations, the Company began presenting these operations as discontinued operations during the fourth quarter of 2010. The following is selected financial information of the discontinued operations for the sale of the Company’s landfill gas operations: Operating Revenues . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $9,919 8,933 Operating Expenses . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2010 2008 Year Ended September 30 2009 (Thousands) $ 6,309 10,705 $3,524 883 Operating Income (Loss) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The division of the Company’s operations into reportable segments is based upon a combination of factors including differences in products and services, regulatory environment and geographic factors. The Utility segment operations are regulated by the NYPSC and the PaPUC and are carried out by Distribution Corporation. Distribution Corporation sells natural gas to retail customers and provides natural gas transportation services in western New York and northwestern Pennsylvania. The Pipeline and Storage segment operations are regulated by the FERC for both Supply Corporation and Empire. Supply Corporation transports and stores natural gas for utilities (including Distribution Corporation), natural gas marketers (including NFR), exploration and production companies (including Seneca) and pipeline companies in the northeastern United States markets. Empire transports natural gas from the United States/ Canadian border near Buffalo, New York into Central New York just north of Syracuse, New York. Empire’s new facilities (the Empire Connector), which consists of a compressor station and a pipeline extension from near Rochester, New York to an interconnection near Corning, New York with the unaffiliated Millennium Pipeline, 116 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) were placed into service on December 10, 2008. Empire transports gas to major industrial companies, utilities (including Distribution Corporation) and power producers. The Exploration and Production segment, through Seneca, is engaged in exploration for, and development and purchase of, natural gas and oil reserves in California, in the Appalachian region of the United States, and in the shallow waters of the Gulf Coast region of Texas and Louisiana. Seneca’s production is, for the most part, sold to purchasers located in the vicinity of its wells. As disclosed in Note M — Acquisition, on July 20, 2009, Seneca acquired Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million (including cash acquired). Ivanhoe Energy’s United States oil and gas operations were incorporated into the Company’s consolidated financial statements for the period subsequent to the completion of the acquisition on July 20, 2009. The Energy Marketing segment is comprised of NFR’s operations. NFR markets natural gas to industrial, wholesale, commercial, public authority and residential customers primarily in western and central New York and northwestern Pennsylvania, offering competitively priced natural gas for its customers. The data presented in the tables below reflect financial information for the segments and reconciliations to consolidated amounts. The accounting policies of the segments are the same as those described in Note A — Summary of Significant Accounting Policies. Sales of products or services between segments are billed at regulated rates or at market rates, as applicable. The Company evaluates segment performance based on income before discontinued operations, extraordinary items and cumulative effects of changes in accounting (when applicable). When these items are not applicable, the Company evaluates performance based on net income.

Note L — Investments in Unconsolidated Subsidiaries The Company’s unconsolidated subsidiaries consist of equity method investments in Seneca Energy, Model City, and ESNE. The Company has 50% interests in each of these entities. Seneca Energy and Model City generate and sell electricity using methane gas obtained from landfills owned by outside parties. ESNE is an 80- megawatt, combined cycle, natural gas-fired power plant in North East, Pennsylvania that is in the process of 119 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) being dismantled. The Company expects to recover its investment in ESNE through the sale of ESNE’s major assets, such as the turbines. During the quarter ended December 31, 2008, the Company recorded a pre-tax impairment of $1.8 million ($1.1 million on an after-tax basis) of its equity investment in ESNE due to a decline in the fair market value of ESNE. The impairment was driven by a significant decrease in “run time” for the plant given the economic downturn and the resulting decrease in demand for electric power. A summary of the Company’s investments in unconsolidated subsidiaries at September 30, 2010 and 2009 is as follows: At September 30 2010 2009 (Thousands) Seneca Energy . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $11,007 2,017 Model City . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1,804 ESNE . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $10,924 2,136 1,880 $14,828 $14,940 Note M — Acquisition On July 20, 2009, the Company’s wholly-owned subsidiary in the Exploration and Production segment, Seneca, acquired all of the shares of Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million in cash (including cash acquired), of which $2.0 million was held in escrow at September 30, 2010 and 2009. Seneca placed this amount in escrow as part of the purchase price. Currently, the Company and Ivanhoe Energy are negotiating a final resolution to the issue of whether Ivanhoe Energy is entitled to some or all of the amount held in escrow. Ivanhoe Energy’s United States oil and gas operations were incorporated into the Company’s consolidated financial statements for the period subsequent to the completion of the acquisition on July 20, 2009. As of the acquisition date, these assets produced approximately 645 (595 net) barrels per day of oil in California and Texas. The purchase also included certain exploration acreage in California. This acquisition added to the Company’s existing oil producing assets in the Midway Sunset Field in California. The acquisition consisted of approximately $37.1 million in property, plant and equipment, $6.2 million of current assets (including $2.0 million of cash held in escrow), $0.3 million of current liabilities and $3.8 million of deferred credits.

In the case of the Empire acquisition, the intangible assets represent the fair value of various long-term transportation contracts with Empire’s customers. These intangible assets are being amortized over the lives of the transportation contracts with no residual value at the end of the amortization period. The weighted- average amortization period for the gross carrying amount of the transportation contracts is 8 years. In the case of the Toro acquisition, the intangible assets represented the fair value of various long-term gas purchase contracts with the various landfills. On September 1, 2010, the Company sold its landfill gas operations in the states of Ohio, Michigan, Kentucky, Missouri, Maryland and Indiana and these operations have been presented 120 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) as discontinued operations in the Company’s financial statements as of September 30, 2010. Refer to Note J — Discontinued Operations for further details.

At September 30, 2010, the 11 months of amortization expense for discontinued operations was $1,286. In September 2009, the Company recorded a pre-tax impairment of $4.6 million in the value of certain long-lived assets in the All Other category due to the loss of the primary customer at one of Toro’s landfill gas sites and the anticipated shut-down of the site. The impairment was comprised of a $2.6 million reduction in intangible assets related to long-term gas purchase contracts and a $2.0 million reduction in property, plant and equipment. The $2.6 million intangible assets impairment was recorded to Purchased Gas expense and the $2.0 million property, plant and equipment impairment was recorded to Depreciation, Depletion and Amortization expense on the Consolidated Statement of Income. The $2.6 million impairment of the intangible asset is included in amortization expense for the year ended September 30, 2009 in the table shown above. As noted above, the Company’s landfill gas operations were sold in September 2010 and have been presented as discontinued operations on the Company’s financial statements. Therefore, this impairment has been included in discontinued operations. In conjunction with the sale of the Company’s landfill gas operations, the carrying amount of intangible assets subject to amortization related to the long-term gas purchase contracts was reduced from a $31.9 million gross carrying amount ($19.5 million net carrying amount) at September 30, 2009 to zero at September 30, 2010. Aside from this change, the only activity with regard to intangible assets subject to amortization was amortization expense as shown in the table above. Amortization expense for the long-term transportation contracts is estimated to be $0.4 million annually for 2011, 2012, 2013 and 2014 and $0.1 million in 2015. 121 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Note O — Quarterly Financial Data (unaudited) In the opinion of management, the following quarterly information includes all adjustments necessary for a fair statement of the results of operations for such periods.

Reserve Quantity Information The Company’s proved oil and gas reserves are located in the United States. The Company’s proved oil and gas reserve estimates are prepared by the Company’s reservoir engineers who meet the qualifications of Reserve Estimator per the “Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information” promulgated by the Society of Petroleum Engineers as of February 19, 2007. The Company maintains comprehensive internal reserve guidelines and a continuing education program designed to keep its staff up to date with current SEC regulations and guidance. The Company’s Vice President of Reservoir Engineering is the primary technical person responsible for overseeing the Company’s reserve estimation process and engaging and overseeing the third party reserve audit. His qualifications include a Bachelor of Science Degree in Petroleum Engineering and over 25 years of Petroleum Engineering experience with both major and independent oil and gas companies. He has maintained oversight of the Company’s reserve estimation process for the past seven years. He is a member of the Society of Petroleum Engineers and a Registered Professional Engineer in the State of Texas. The Company maintains a system of internal controls over the reserve estimation process. Management reviews the price, heat content, lease operating cost and future investment assumptions used in the economic model to determine the reserves. The Vice President of Reservoir Engineering reviews and approves all new reserve assignments and significant reserve revisions. Access to the Reserve database is restricted. Significant changes to the reserve report are reviewed by senior management on a quarterly basis. Periodically, the Company’s internal audit department assesses the design of these controls and performs testing to determine the effectiveness of such controls. All of the Company’s reserve estimates are audited annually by Netherland, Sewell and Associates, Inc. (NSAI). Since 1961, NSAI has evaluated gas and oil properties and independently certified petroleum reserve 125 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) quantities in the United States and internationally under the Texas Board of Professional Engineers Registration No. F-002699. The primary technical persons (employed by NSAI) that are responsible for leading the audit include an engineer registered with the State of Texas (with 12 years of experience in petroleum engineering and six years of experience in the estimation and evaluation of reserves) and a Certified Petroleum Geologist and Geophysicist in the State of Texas (with 32 years of experience in petroleum geosciences and 21 years of experience in the estimation and evaluation of reserves). The reliable technologies that were utilized in estimating the reserves include wire line open-hole log data, performance data, log cross sections, core data, and statistical analysis. The statistical method utilized production performance from both the Company’s and competitor’s wells. Geophysical data include data from the Company’s wells, published documents, and state data-sites and were used to confirm continuity of the formation. Extension and discovery reserves added as a result of reliable technologies were not material.

This was primarily attributable to a 19,484 MMcf reduction in the Appalachian region offset by a 9,407 MMcf increase in the Gulf Coast region. The reduction in the Appalachian region was mainly due to declining natural gas prices, which made certain reserves uneconomical. The improvement in the Gulf Coast region was due to improved performance of Gulf Coast properties. (2) Extensions and discoveries include 182 Bcf of Marcellus Shale gas in the Appalachian Region. (3) Production includes 7,180 MMcf from Marcellus Shale fields (which exceed 15% of total reserves). 127 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Oil Mbbl Gulf Coast Region U.

The Company’s proved undeveloped (PUD) reserves increased from 87 Bcfe at September 30, 2009 to 177 Bcfe at September 30, 2010. Undeveloped reserves in the Marcellus Shale increased from 11 Bcf at September 30, 2009 to 110 Bcf at September 30, 2010. There was a material increase in undeveloped reserves at September 30, 2010 as a result of its Marcellus Shale reserve additions. The increase in undeveloped reserves in the Marcellus Shale is partially attributable to the change in SEC regulations allowing the recognition of PUD reserves more than one direct offset location away from existing production with reasonable certainty using reliable technology. The Company’s total PUD reserves are 25% of total proved reserves at September 30, 2010, up from 16% of total proved reserves at September 30, 2009. 128 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The increase in PUD reserves in 2010 of 90 Bcfe is a result of 111 Bcfe in new PUD reserve additions (105 Bcfe from the Marcellus Shale), offset by 17 Bcfe in PUD conversions to developed reserves and 4 Bcfe in downward PUD revisions. The downward revisions were primarily from the removal of 51 PUD locations in the Upper Devonian play. This was the result of Seneca’s decision in 2010 to significantly reduce its 5-year investment plan for the Upper Devonian as a result of lower forward gas price expectations. The Company invested $28.9 million during the year ended September 30, 2010 to convert 17 Bcfe of PUD reserves to developed reserves. This represents 19% of the PUD reserves booked at September 30, 2009. In 2011, the Company estimates that it will invest approximately $140 million to develop the PUD reserves. The Company is committed to developing its PUD reserves within five years of being recorded as PUD reserves as required by the SEC’s final rule on Modernization of Oil and Gas Reporting. At September 30, 2010, the Company does not have a material concentration of proved undeveloped reserves that have been on the books for more than five years at the corporate level or country level. All of the Company’s proved reserves are in the United States. At the field level, only at the North Lost Hills Field in Kern County, California, does the Company have a material concentration of undeveloped reserves that have been on the books for more than five years. The Company has reduced the concentration of undeveloped reserves in this field from 61% of total field level reserves at September 30, 2005 to 24% of total field level reserves at September 30, 2010. The Company has been actively drilling undeveloped locations in this field for four out of the past five years, drilling 53 undeveloped locations and converting 3.1 million barrels of proved reserves from undeveloped to developed reserves. The undeveloped reserves in this field represent less than 2% of the Company’s proved reserves at the corporate level. The Company is committed to drilling the remaining proved undeveloped locations within five years of being recorded as PUD reserves. Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves The Company cautions that the following presentation of the standardized measure of discounted future net cash flows is intended to be neither a measure of the fair market value of the Company’s oil and gas properties, nor an estimate of the present value of actual future cash flows to be obtained as a result of their development and production. It is based upon subjective estimates of proved reserves only and attributes no value to categories of reserves other than proved reserves, such as probable or possible reserves, or to unproved acreage. Furthermore, as a result of the SEC’s final rule on Modernization of Oil and Gas Reporting (effective fiscal 2010), it is based on the unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period and costs adjusted only for existing contractual changes. It assumes an arbitrary discount rate of 10%. Thus, it gives no effect to future price and cost changes certain to occur under widely fluctuating political and economic conditions. 129 NATIONAL FUEL GAS COMPANY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The standardized measure is intended instead to provide a means for comparing the value of the Company’s proved reserves at a given time with those of other oil- and gas-producing companies than is provided by a simple comparison of raw proved reserve quantities. 2010 Year Ended September 30 2009 (Thousands) 2008 United States Future Cash Inflows. . . . . . . . . . . . . . . . . . . . . . . . . . . $5,273,605 $3,972,026 $5,845,214 Less: Future Production Costs . . . . . . . . . . . . . . . . . . . .

Item 9 Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None Item 9A Controls and Procedures Evaluation of Disclosure Controls and Procedures The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. These rules refer to the controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. The Company’s management, including the Chief Executive Officer and Principal Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, the Company’s Chief Executive Officer and Principal Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2010. Management’s Annual Report on Internal Control over Financial Reporting The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and preparation of financial statements for external purposes in accordance with GAAP. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of September 30, 2010. In making this assessment, management used the framework and criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Based on this assessment, management concluded that the Company maintained effective internal control over financial reporting as of September 30, 2010. 131 PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of September 30, 2010. The report appears in Part II, Item 8 of this Annual Report on Form 10-K. Changes in Internal Control over Financial Reporting On October 1, 2010, the Company replaced The Northern Trust Company with JPMorgan Chase Bank, NA as trustee and custodian of assets held in trust for the beneficiaries of the Company’s qualified defined-benefit retirement plan and other post-retirement benefit plans. The change in trustee is a result of an appraisal by the Company’s Retirement Committee of outsourced trust and custodial services and is not the result of any actual or perceived deficiencies in internal controls at the previous trustee. The impact of the change, including the transfer of trust assets on October 1, 2010, has been evaluated by management and adequately incorporated into management’s ongoing monitoring of internal controls over financial reporting. On November 1, 2010, Seneca implemented Quorum Business Solutions software as its Enterprise Resource Planning Accounting System and Land/Geographical Information System to help support the growth of the Exploration and Production segment. These system changes are a result of an evaluation of the previous accounting and land systems and related processes to support evolving needs and are not the result of any actual or perceived deficiencies in the previous systems. These implementations resulted in certain changes to Seneca’s processes and internal controls impacting financial reporting. While there are inherent risks involved with the implementation of any new system, management believes that it is adequately monitoring and managing the transition. There were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended September 30, 2010 and no changes through the filing date of this Annual Report on Form 10-K with the SEC, other than the changes that occurred on October 1, 2010 and November 1, 2010, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

This Annual Report contains “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995. Forward-looking statements should be read with the cautionary statements and important factors included in the Company’s Form 10-K at Item 7, MD&A, under the heading “Safe Harbor for Forward- Looking Statements,” and with the “Risk Factors” included in the Company’s Form 10-K at Item 1A. Forward-looking statements are all statements other than statements of historical fact, including, without limitation, statements regarding future prospects, plans, objectives, goals, projections, estimates of oil and gas quantities, strategies, future events or performance and underlying assumptions, capital structure, anticipated capital expenditures, completion of construction and other projects, projections for pension and other post-retirement benefit obligations, impacts of the adoption of new accounting rules, and possible outcomes of litigation or regulatory proceedings, as well as statements that are identified by the use of the words “anticipates,” “estimates,” “expects,” “forecasts,” “intends,” “plans,” “predicts,” “projects,” “believes,” “seeks,” “will,” “may” and similar expressions. Forward-looking statements include estimates of oil and gas quantities. Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible under existing economic conditions, operating methods and government regulations. Other estimates of oil and gas quantities, including estimates of probable reserves, possible reserves, and resource potential, are by their nature more speculative than estimates of proved reserves. Accordingly, estimates other than proved reserves are subject to substantially greater risk of being actually realized. This Annual Report and the statements contained herein are submitted for the general information of stockholders and employees of the Company and are not intended to induce any sale or purchase of securities or to be used in connection therewith.
