Ladies and Gentlemen:

Introductory. National Fuel Gas Company, a New Jersey corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”), acting severally and not jointly, the respective amounts set forth in such Schedule A of $500,000,000 aggregate principal amount of the Company’s 4.90% Notes due 2021 (the “Notes”). ▇.▇. ▇▇▇▇▇▇ Securities LLC, ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated and ▇▇▇▇▇ Fargo Securities, LLC have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Notes. If there are no Underwriters named in Schedule A other than the Representatives, then the term “Underwriters” and “Representatives” shall each be deemed to refer to the Underwriters.

The Notes will be issued pursuant to an indenture, dated as of October 1, 1999, between the Company and The Bank of New York Mellon (formerly The Bank of New York), as trustee (the “Trustee”), including an Officer’s Certificate pursuant thereto (the “Indenture”). The Notes will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a Blanket Letter of Representations, to be dated on or before the Closing Date (as defined in Section 2(b) hereof) (the “DTC Agreement”), between the Company and the Depositary.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-158060), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of debt securities, including the Notes, and other securities of the Company under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), and the offering thereof from time to time in accordance with Rule 415 under the Securities Act. Such registration statement, including the financial statements, exhibits and schedules thereto, at each time of effectiveness under the Securities Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act, is called the “Registration Statement.” The term “Prospectus” shall mean the final prospectus supplement relating to the Notes, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) under the Securities Act after the date and time that this Agreement is executed (the “Execution Time”) by the parties hereto. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Notes, together with the Base Prospectus, that is first filed with the Commission pursuant to such Rule 424(b) prior to the time of filing the Prospectus. Any reference herein to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents that are or are deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act prior to 4:30 p.m. on the date of this Agreement (the “Initial Sale Time”). All references in this Agreement to the Registration Statement, the Preliminary Prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

All references in this Agreement to financial statements and schedules and other information that is “contained,” “included,” “set forth,” “disclosed” or “stated” (or other references of like import) in the Registration Statement, the Prospectus or the Preliminary Prospectus shall be deemed to mean and include all such financial statements and schedules and other information that is or is deemed to be incorporated by reference in the Registration Statement, the Prospectus or the Preliminary Prospectus, as the case may be, prior to the Initial Sale Time; and all references in this Agreement to amendments or supplements to the Registration Statement, the Prospectus or the Preliminary Prospectus shall be deemed to include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”) that is or is deemed to be incorporated by reference in the Registration Statement, the Prospectus or the Preliminary Prospectus, as the case may be, after the Initial Sale Time.

The Company hereby confirms its agreements with the Underwriters as follows:

Section 1. Representations and Warranties of the Company

The Company hereby represents, warrants and covenants to each Underwriter as of the date hereof, as of the Initial Sale Time and as of the Closing Date (in each case, a “Representation Date”), as follows:

(a) Compliance with Registration Requirements. The Company meets the requirements for use of Form S-3 under the Securities Act. The Registration Statement has

become effective under the Securities Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated or threatened by the Commission, and any request on the part of the Commission for additional information has been complied with. In addition, the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and the rules and regulations promulgated thereunder (collectively, the “Trust Indenture Act”).

At the respective times the Registration Statement and any amendments thereto became effective (including the filing with the Commission of the Company’s Annual Report on Form 10-K for the year ended September 30, 2011 (the “Annual Report”)) and at each Representation Date, the Registration Statement and any amendments thereto (i) complied and will comply in all material respects with the requirements of the Securities Act and the Trust Indenture Act and (ii) did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At the date of the Prospectus and at the Closing Date, neither the Prospectus nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the representations and warranties in this Section 1(a) shall not apply to statements in or omissions from the Registration Statement or any post-effective amendment or the Prospectus or any amendments or supplements thereto made in reliance upon and in conformity with information furnished to the Company in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 9 hereof.

Each Preliminary Prospectus and the Prospectus, at the time each was filed with the SEC, complied in all material respects with the Securities Act, and the Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Notes will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(b) Disclosure Package. The term “Disclosure Package” shall mean (i) the Preliminary Prospectus dated November 28, 2011, (ii) any Issuer Free Writing Prospectus (as defined below), excluding any road show within the meaning of Rule 433 under the Securities Act and (iii) any other “free writing prospectus” (as defined in Rule 405 under the Securities Act) that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. As of the Initial Sale Time, the Disclosure Package did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 9 hereof. For purposes of

this Agreement, an “Issuer Free Writing Prospectus” means each “issuer free writing prospectus” (as defined in Rule 433 under the Securities Act) identified in Annex I hereto, including, without limitation, any road show within the meaning of Rule 433 under the Securities Act.

(c) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus (i) at the time they were or hereafter are filed with the Commission, complied or will comply in all material respects with the requirements of the Exchange Act and (ii) when read together with the other information in the Disclosure Package, at the Initial Sale Time, and when read together with the other information in the Prospectus, at the date of the Prospectus and at the Closing Date, did not or will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Company is a Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether by virtue of the filing of any post-effective amendment, any document incorporated by reference therein pursuant to Section 13(a) or 15(d) of the Exchange Act or any form of prospectus pursuant to Rule 424(b) under the Securities Act) and (iii) at the Execution Time (with the date thereof being used as the determination date for purposes of this clause (iii)), the Company was and is a “well-known seasoned issuer” (as defined in Rule 405 under the Securities Act). The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act) that automatically became effective within three years of the date hereof. The Company has not (A) received from the Commission any notice pursuant to Rule 401(g)(2) under the Securities Act objecting to the use of the automatic shelf registration statement form or (B) ceased to be eligible to use the automatic shelf registration statement form.

(e) Company is not an Ineligible Issuer. (i) At the time of filing the Registration Statement and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405 under the Securities Act), without taking account of any determination by the Commission pursuant to such Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

(f) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of the Notes under this Agreement or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus. Each Issuer Free Writing Prospectus, when considered together with the Disclosure Package, did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. If at any time following the issuance of an Issuer Free Writing Prospectus and during the Prospectus Delivery Period (as defined in Section 3(e) hereof), there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus

conflicted or would conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus, the Company has promptly notified or will promptly notify the Representatives and has promptly amended or supplemented or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon, and in conformity with, written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 9 hereof.

(g) No Applicable Registration or Other Similar Rights. There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, except for such rights as have been duly waived.

(h) The Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by the Company.

(i) Authorization of the Notes and the Indenture. The Notes have been duly authorized by the Company and, when the Notes have been duly executed by the Company and authenticated by the Trustee, in accordance with the provisions of the Indenture and upon payment and delivery in accordance with this Agreement, the Notes will constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture; the Indenture has been duly authorized by the Company and qualified under the Trust Indenture Act and constitutes a valid and legally binding instrument of the Company; and the Indenture is, and the Notes, when executed and authenticated and upon payment and delivery as aforesaid, will be enforceable in accordance with their respective terms, except as the same may be limited by (i) bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar laws affecting the enforcement of creditors’ rights and remedies generally and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including, without limitation, (A) the possible unavailability of specific performance, injunctive relief or any other remedy and (B) concepts of materiality, reasonableness, good faith, fair dealing and equitable subordination.

(j) Description of the Notes and the Indenture. The Notes and the Indenture conform in all material respects to the descriptions thereof contained in the Disclosure Package and the Prospectus.

(k) Accuracy of Statements in Prospectus. The statements in each of the Preliminary Prospectus and the Prospectus under (i) the captions “Description of the Notes” and “Description of Debt Securities,” in each case insofar as such statements constitute a summary of the legal matters, documents or proceedings referred to therein, fairly present and summarize, in all material respects, the matters referred to therein and (ii) the caption “Certain U.S. Federal Tax Considerations for U.S. Holders,” insofar as such statements constitute a summary of law and legal conclusions, and subject to the qualifications set forth therein, are correct in all material respects.

(l) No Material Adverse Change. Except as set forth in the Disclosure Package, subsequent to the respective dates as of which information is given in the Disclosure Package, there has not been (i) any material adverse change in the business, properties or financial condition of the Company and its subsidiaries considered as one enterprise (any such change is called a “Material Adverse Change”) or (ii) any material transaction entered into by the Company other than transactions disclosed in the Disclosure Package and transactions in the ordinary course of business.

(m) Independent Accountants. PricewaterhouseCoopers LLP, who have expressed their opinion with respect to the Company’s audited financial statements incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus, are independent public accountants with respect to the Company as required by the Securities Act and the Exchange Act and are an independent registered public accounting firm with the Public Company Accounting Oversight Board.

(n) Preparation of the Financial Statements. The financial statements, including the related notes thereto, incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus present fairly in all material respects the consolidated financial position of the Company and its subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. Such financial statements comply as to form with the accounting requirements of the Securities Act and have been prepared in conformity with generally accepted accounting principles as applied in the United States applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. No other financial statements are required to be included in the Registration Statement. The summary financial data and the selected financial data included or incorporated by reference in the Preliminary Prospectus and the Prospectus present fairly in all material respects the information shown therein and have been compiled on a basis consistent with that of the audited financial statements incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus.

(o) Incorporation and Good Standing of the Company. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of New Jersey with corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package and the Prospectus; and the Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change.

(p) Incorporation and Good Standing of Significant Subsidiaries. Each of National Fuel Gas Distribution Corporation, National Fuel Gas Supply Corporation and Seneca Resources Corporation (“Seneca”) is a significant subsidiary of the Company (as such term is defined in Rule 1-02(w) of Regulation S-X) (each, a “Significant Subsidiary” and, collectively, the “Significant Subsidiaries”), has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has corporate power and authority to own, lease and operate its properties and to conduct its business as

described in the Disclosure Package and the Prospectus and is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change; all of the issued and outstanding capital stock of each such Significant Subsidiary has been duly authorized and validly issued, is fully paid and non-assessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim. The Company did not have any subsidiary not listed on Exhibit 21 to the Annual Report that was required to be so listed.

(q) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. The consummation of the transactions herein contemplated and the fulfillment of the terms hereof will not result in a breach of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, (i) the Company’s Restated Certificate of Incorporation or By-Laws, each as amended, or any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of its Significant Subsidiaries is now a party or (ii) any statute, law, order, rule or regulation applicable to the Company of any court or any federal or state governmental body having jurisdiction over the Company or its properties. No authorization, approval or consent of, or registration or filing with, any court or governmental authority or agency (including the Federal Energy Regulatory Commission) is necessary in connection with the sale of the Notes hereunder, except such as may be required under the Securities Act and the Trust Indenture Act and in each case the rules and regulations of the Commission thereunder, or state securities or “blue sky” laws.

(r) No Material Actions or Proceedings. Except as disclosed in the Prospectus and the Disclosure Package, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject that, if determined adversely to the Company or any of its subsidiaries, would, individually or in the aggregate, result in a Material Adverse Change; and, to the best of the Company’s knowledge, except as disclosed in the Prospectus and the Disclosure Package, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

(s) Compliance with Environmental Laws. Except as disclosed in the Prospectus and the Disclosure Package, (i) to the knowledge of the Company after due inquiry, the Company is in compliance with any and all applicable federal, state and local laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) the Company has received all permits, licenses or other approvals required of it under applicable Environmental Laws to conduct its business and (iii) to the knowledge of the Company after due inquiry, the Company is in compliance with all terms and conditions of any such permit, license or approval, except where such non-compliance with Environmental Laws, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of required permits, licenses or approvals would not, singly or in the aggregate, reasonably be expected to cause a Material Adverse Change.

(t) ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Compliance. The Company is in compliance in all material respects, with all provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications.

(u) Company’s Accounting System. The Company and its subsidiaries maintain effective internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act.

(v) Internal Controls and Procedures. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(w) No Material Weakness in Internal Controls. Except as disclosed in the Disclosure Package and the Prospectus, since the end of the Company’s most recent audited fiscal year, (i) the Company is not aware of any material weaknesses in its internal control over financial reporting (whether or not remediated) and (ii) there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(x) Accuracy of Exhibits. There are no franchises, contracts or documents that are required to be described in the Registration Statement, the Disclosure Package, the Prospectus or to be filed as exhibits to the Registration Statement that have not been so described or filed as required.

(y) Title to Property. Methods used in connection with investigating title to properties, or interests therein, owned by each of the subsidiaries of the Company in the States of California, New York, Texas and the Commonwealth of Pennsylvania are consistent with good practice and established methods used by prudent companies engaged in similar businesses and are adequately designed to provide for the acquisition of such titles or interests. Substantially all of the properties now owned by such subsidiaries in the States of California, New York, Texas and the Commonwealth of Pennsylvania are held without any unfavorable adjudicated claim.

Any certificate signed by an officer of the Company and delivered to the Representatives or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company to each Underwriter as to the matters set forth therein.

Section 2. Purchase, Sale and Delivery of the Notes.

(a) The Notes. The Company agrees to issue and sell to the several Underwriters, severally and not jointly, all of the Notes upon the terms herein set forth. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Underwriters agree, severally and not jointly, to purchase

from the Company the aggregate principal amount of Notes set forth opposite their names on Schedule A at a purchase price of 99.217% of the principal amount of the Notes, payable on the Closing Date.

(b) The Closing Date. Delivery of certificates for the Notes in global form to be purchased by the Underwriters and payment therefor shall be made at the offices of ▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, 1301 Avenue of the Americas, New York, New York (or such other place as may be agreed to by the Company and the Representatives) at 9:00 a.m., New York City time, on December 1, 2011, or such other time and date as the Underwriters and the Company shall mutually agree (the time and date of such closing are called the “Closing Date”).

(c) Public Offering of the Notes. The Representatives hereby advise the Company that the Underwriters intend to offer for sale to the public, as described in the Disclosure Package and the Prospectus, their respective portions of the Notes as soon after the Execution Time as the Representatives, in their sole judgment, have determined is advisable and practicable.

(d) Payment for the Notes. Payment for the Notes shall be made at the Closing Date by wire transfer of immediately available funds to the order of the Company.

It is understood that the Representatives have been authorized, for their own accounts and for the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Notes that the Underwriters have agreed to purchase. The Representatives may (but shall not be obligated to) make payment for any Notes to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the Closing Date for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(e) Delivery of the Notes. The Company shall deliver, or cause to be delivered, to the Representatives for the accounts of the several Underwriters certificates for the Notes at the Closing Date, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The certificates for the Notes shall be in such denominations and registered in such names and denominations as the Representatives shall have requested at least two full business days prior to the Closing Date and shall be made available for inspection on the business day preceding the Closing Date at a location in New York City, as the Representatives may designate. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters.

Section 3. Covenants of the Company.

The Company covenants and agrees with each Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Request. The Company, subject to Section 3(b) hereof, will comply with the requirements of Rule 430B under the Securities Act, and will promptly notify the Representatives, after it receives notice thereof, and confirm the notice in writing, of (i) the effectiveness during the Prospectus Delivery Period of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Preliminary Prospectus or the Prospectus, (ii) any comments from the

Commission during the Prospectus Delivery Period or any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Preliminary Prospectus or the Prospectus or for additional information and (iii) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Preliminary Prospectus or the Prospectus, or of the suspension of the qualification of the Notes for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will use its commercially reasonable best efforts to obtain the lifting of any such stop order at the earliest possible moment. The Company will promptly effect the filings necessary pursuant to Rule 424 under the Securities Act and will take such steps as it deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under such Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file such document.

(b) Filing of Amendments. The Company will (i) after the date of this Agreement and prior to the Closing Date, make no amendment or supplement to the Registration Statement, the Disclosure Package or the Prospectus as amended or supplemented relating to the Notes that shall be reasonably disapproved by the Representatives after reasonable notice thereof and (ii) after the Closing Date and prior to the time the Representatives notify the Company as to the completion of the distribution of the Notes, advise and furnish the Representatives with copies of any such amendment or supplement a reasonable amount of time prior to the making thereof.

(c) Delivery of Registration Statement. The Company will deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and of any amendment thereto (without exhibits) for each of the Underwriters. The Registration Statement and each amendment thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company will deliver to each Underwriter, without charge, as many copies of the Preliminary Prospectus as such Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes permitted by the Securities Act. The Company will furnish to each Underwriter, without charge, during the Prospectus Delivery Period, such number of copies of the Prospectus as such Underwriter may reasonably request. The Preliminary Prospectus and the Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the Securities Act and the Exchange Act so as to permit the completion of the distribution of the Notes as contemplated in this Agreement and in the Registration Statement, the Disclosure Package and the Prospectus. If, during the period that delivery of a prospectus is required at any time in connection with the offering or sale of the Notes, including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act (the “Prospectus Delivery Period”), any event shall occur as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state a material fact

necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus is delivered, not misleading, or, if for any other reason it shall be necessary during the Prospectus Delivery Period to amend or supplement the Prospectus in order to comply with the Securities Act, the Exchange Act or the Trust Indenture Act, the Company will notify the Representatives thereof and upon their reasonable request to file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such statement or omission or to make the Prospectus so comply, and the Company will furnish without charge to each Underwriter and to any dealer in securities such number of copies of such amendment or supplement as the Representatives may reasonably request.

(f) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Notes for sale under (or obtain exemptions from the application of) the state securities or “blue sky” laws of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Notes. The Company shall not be required to qualify to transact business or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign business. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification or registration of (or any such exemption relating to) the Notes for offering, sale or trading in any jurisdiction or the initiation or threatening of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

(g) Use of Proceeds. The Company shall apply the net proceeds from the sale of the Notes sold by it in the manner described under the caption “Use of Proceeds” in the Preliminary Prospectus and the Prospectus.

(h) Depositary. The Company will cooperate with the Underwriters and use its best efforts to permit the Notes to be eligible for clearance and settlement through the facilities of the Depositary.

(i) Periodic Reporting Obligations. During the Prospectus Delivery Period, the Company shall file, on a timely basis, with the Commission all reports and documents required to be filed under the Exchange Act.

(j) Agreement Not to Offer or Sell Additional Securities. During the period commencing on the date hereof and ending on the Closing Date, the Company will not, without the prior written consent of the Representatives (which consent may be withheld at the sole discretion of the Representatives), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration statement under the Securities Act in respect of, any debt securities of the Company similar to the Notes or securities exchangeable for or convertible into debt

securities similar to the Notes (other than as contemplated by this Agreement with respect to the Notes).

(k) Final Term Sheet. The Company will prepare a final term sheet containing only a description of the Notes, in a form approved by the Underwriters and attached as Exhibit D hereto, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

(l) Notice of Inability to Use Automatic Shelf Registration Statement Form. If at any time during the Prospectus Delivery Period the Company receives from the Commission a notice pursuant to Rule 401(g)(2) under the Securities Act or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Notes, in a form satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Notes to continue as contemplated in the registration statement that was the subject of such notice under Rule 401(g)(2) under the Securities Act or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

(m) Filing Fees. The Company agrees to pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1) under the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act.

The Representatives, on behalf of the several Underwriters, may, in their sole discretion, waive in writing the performance by the Company of any one or more of the foregoing covenants or extend the time for their performance.

Section 4. Permitted Free Writing Prospectuses. The Company represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 under the Securities Act; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of any Issuer Free Writing Prospectuses included in Annex I to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with

the Commission, legending and record keeping. Each Underwriter represents and agrees that, unless it obtains the prior written consent of the Company and the Representatives, it has not and will not make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) that would be required to be filed with the Commission, other than information contained in the Final Term Sheet prepared and filed pursuant to Section 3(k) hereof. Prior to the preparation of the Final Term Sheet in accordance with Section 3(k) hereof, the Company and the Representatives consent to the use of the information with respect to the final terms of the Notes in communications by the Underwriters conveying information relating to the offering thereof to investors.

Section 6. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Notes as provided herein on the Closing Date shall be subject to the accuracy of the representations and warranties on the part of the Company set forth in Section 1 hereof as of each Representation Date as though then made and to the timely performance by the Company of its covenants and other obligations hereunder, and to each of the following additional conditions:

Section 8. Effectiveness of this Agreement. This Agreement shall not become effective until the execution of this Agreement by the parties hereto.

Section 9. Indemnification.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers, employees, agents and affiliates (as such

term is defined in Rule 501(b) under the Securities Act (each, an “Affiliate”)), and each person, if any, who controls any Underwriter within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such director, officer, employee, agent, Affiliate or controlling person may become subject, under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse each Underwriter and each such director, officer, employee, agent, Affiliate and controlling person for any and all expenses (including the reasonable fees and disbursements of counsel chosen by the Representatives) as such expenses are reasonably incurred by such Underwriter or such director, officer, employee, agent, Affiliate or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 9(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company, its Directors and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company or any such director, officer or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were

made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein; and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company hereby acknowledges that the only information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) are the statements regarding delivery of the Notes by the Underwriters set forth in the last paragraph on the cover page of, and the concession and reallowance figures and the paragraphs relating to stabilization of the Notes appearing under the caption “Underwriting” in, the Preliminary Prospectus and the Prospectus. The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 9 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized in writing by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it that are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by the Representatives and that all such reasonable fees and expenses shall be reimbursed as they are

incurred). Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence, in which case the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 9 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 9(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

Section 10. Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein in such proportion as is appropriate to reflect (i) the relative benefits received by the Company and the Underwriters from the offering of the Notes pursuant to this Agreement, (ii) the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses and (iii) any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Company, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus bear to the aggregate initial public offering price of the Notes as set forth on such cover. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact

relates to information supplied by the Company, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 9(c), any reasonable legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 10.

Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 10 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 10, each director, officer, employee, agent and Affiliate of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

Section 11. Default of One or More of the Several Underwriters. If, on the Closing Date, any one or more of the several Underwriters shall fail or refuse to purchase Notes that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes, which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Notes to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportion to the aggregate principal amounts of such Notes set forth opposite their respective names on Schedule A bears to the aggregate principal amount of such Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase such Notes that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase such Notes and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 5, 7, 9, 10 and 18 hereof shall at all times be effective and shall survive such termination. In any such case, either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 11. Any action taken under this Section 11 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 12. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by written notice given to the Company if at any time since the Execution Time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or the New York Stock Exchange, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the FINRA; (ii) a general banking moratorium shall have been declared by any of federal or New York authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving the United States, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to offer, sell or deliver the Notes in the manner and on the terms described in the Disclosure Package or to enforce contracts for the sale of securities; or (iv) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services. Any termination pursuant to this Section 12 shall be without liability of any party to any other party except as provided in Sections 5 and 7 hereof, and provided further that Sections 5, 7, 9, 10 and 18 hereof shall survive such termination and remain in full force and effect.

Section 13. No Fiduciary Duty. The Company acknowledges and agrees that: (i) the purchase and sale of the Notes pursuant to this Agreement, including the determination of the public offering price of the Notes and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or its affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the several Underwriters with respect to the subject matter hereof.

Section 14. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriter, the Company, the officers or employees of the Company, or any person controlling the Company, as the case may be or (B) acceptance of the Notes and payment for them hereunder and (ii) will survive delivery of and payment for the Notes sold hereunder and any termination of this Agreement.

▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

We have acted as counsel for National Fuel Gas Company, a New Jersey corporation (the “Company”), in connection with the issuance and sale by the Company of an aggregate of $500,000,000 principal amount of 4.90% Notes due 2021 (the “Notes”) pursuant to the Underwriting Agreement dated November 28, 2011 between the Company and the Underwriters named therein (the “Underwriters”), for whom you are acting as Representatives (the “Underwriting Agreement”), being issued under the Company’s Indenture, dated as of October 1, 1999, to The Bank of New York Mellon (formerly The Bank of New York), as Trustee (the “Trustee”), including the terms of the Notes set forth in, or determined in a manner provided in, a certificate dated the date hereof delivered pursuant to Section 301 thereof (the “Indenture”). This opinion is being rendered to you at the Company’s request pursuant to Section 6(e)(i) of the Underwriting Agreement.

We have reviewed: (a) the Company’s Registration Statement on Form S-3 (File No. 333-158060) (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), which pursuant to Form S-3 incorporates by reference the Annual Report on Form 10-K of the Company for the fiscal year ended September 30, 2011 (the “Annual Report”) and Part III of the Annual Report on Form 10-K of the Company for the fiscal year ended September 30, 2010 (collectively, the “Exchange Act Documents”), each as filed under the

A-1

Securities Exchange Act of 1934, as amended (the “Exchange Act”); (b) the Company’s Prospectus dated March 17, 2009, as supplemented by each of (i) the Preliminary Prospectus Supplement, Subject to Completion, dated November 28, 2011 (such Prospectus, as so supplemented, the “Preliminary Prospectus”) and (ii) the Prospectus Supplement dated November 28, 2011 (such Prospectus, as so supplemented, the “Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission (the “Commission”) under the Securities Act, which in each case incorporates by reference the Exchange Act Documents; (c) the Exchange Act Documents; (d) the term sheet reflecting the final terms of the Notes filed by the Company pursuant to Rule 433 of the rules and regulations of the Commission under the Securities Act (the “Term Sheet” and, together with the Preliminary Prospectus, the “Disclosure Package”); (e) the Underwriting Agreement; and (f) the Indenture. In addition, we have reviewed, and have relied as to matters of fact upon, the documents delivered to you at the closing of the transaction contemplated by the Underwriting Agreement, and upon originals or copies, certified or otherwise identified to our satisfaction, of such corporate records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and its subsidiaries, and have made such other and further investigations, as we have deemed relevant and necessary as a basis for the opinions hereinafter set forth. In such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies (whether or not certified, and including facsimiles), and the authenticity of such latter documents.

With respect to legal matters governed by the laws of the State of New Jersey, we understand that you are relying upon the opinion of ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ PC, New Jersey counsel for the Company, dated the date hereof and addressed to you, which is being furnished to you pursuant to the Underwriting Agreement. With respect to certain other legal matters relating to the Company and to the due incorporation of, and various other matters relating to, certain subsidiaries of the Company, we understand that you are relying upon the opinion of ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esq., General Counsel of the Company and counsel for such subsidiaries, dated the date hereof and addressed to you, which is being furnished to you pursuant to the Underwriting Agreement. We do not pass upon the incorporation of the Company.

Based upon the foregoing and subject to the qualifications and limitations stated herein, we hereby advise you that in our opinion:

1. The Company had corporate power and authority to execute the Indenture and the Indenture has been duly authorized, executed and delivered by the Company, has been duly qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and assuming due authorization, execution and delivery thereof by the Trustee, constitutes a legal, valid and binding instrument enforceable against the Company in accordance with its terms, except as the same may be limited by (i) bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar laws affecting the enforcement of creditors’ rights and remedies generally and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including, without limitation, (x) the possible unavailability of specific performance, injunctive

A-2

relief or any other remedy and (y) concepts of materiality, reasonableness, good faith, fair dealing and equitable subordination.

2. The Notes have been duly authorized by the Company and, when the Notes have been duly authenticated by the Trustee in accordance with the provisions of the Indenture and upon payment and delivery in accordance with the Underwriting Agreement, the Notes, subject to the qualifications in paragraph 1 above, will constitute legal, valid and binding obligations of the Company enforceable against the Company in accordance with their terms and entitled to the benefits of the Indenture.

3. The Company is not, and immediately after receipt of payment for the Notes and the application of the proceeds thereof as contemplated under the caption “Use of Proceeds” in the Preliminary Prospectus and the Prospectus will not be, an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

4. The Registration Statement has become and is effective under the Securities Act; and to the best of our knowledge, no proceedings for a stop order with respect thereto are pending or threatened under Section 8 or Section 8A of the Securities Act.

5. The statements made in the Preliminary Prospectus and the Prospectus under “Description of Debt Securities” and “Description of the Notes,” together with the statements made in the Term Sheet, insofar as they purport to constitute summaries of the terms of the Notes and the Indenture, are accurate in all material respects.

6. There are no approvals or consents of, or registrations or filings with, any governmental body of the State of New York or the United States of America legally required for the issuance and sale of the Notes by the Company pursuant to the terms of the Underwriting Agreement, except for such approvals, consents, registrations or filings as may be required under the Securities Act or the Trust Indenture Act or under state or other securities or “blue sky” laws.

7. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

8. The consummation of the transactions pursuant to the terms of the Underwriting Agreement and the fulfillment of the terms thereof will not violate any laws of the State of New York or the Federal law of the United States to which the Company is subject and that, based on our experience, are generally applicable to transactions of the character contemplated by the Prospectus, or any order known to us (after reasonable investigation) applicable to the Company under any such laws of any court or governmental body or instrumentality having jurisdiction over the Company or any of its properties (it being understood that for the purpose of the opinion expressed in this paragraph 8, we are not passing upon state securities or “blue sky” laws or upon compliance with respect to antifraud or similar provision of any law, rule or regulation).

9. The statements made in the Disclosure Package and the Prospectus under “Certain U.S. Federal Income Tax Considerations for U.S. Holders,” insofar as such statements constitute a summary of law and legal conclusions, and subject to the qualifications set forth therein, are correct in all material respects.

A-3

10. The Company is in good standing under the laws of the State of New York.

In passing upon the Registration Statement, the Prospectus and the Exchange Act Documents in clause (a) below, we necessarily assume the correctness and completeness of the statements made by the Company and the information contained or incorporated by reference in the Registration Statement, the Prospectus or the Exchange Act Documents and take no responsibility therefor, except as and to the extent set forth in paragraphs 5 and 9 above or as they relate to us. In the course of the preparation by the Company of the Registration Statement, the Disclosure Package and the Prospectus (excluding the Exchange Act Documents), we participated in conferences with certain of its officers and employees, with other counsel for the Company, with representatives of PricewaterhouseCoopers LLP, the Company’s independent accountants, and with your representatives and your counsel. We did not prepare the Exchange Act Documents or participate in the selection of information contained therein or omitted therefrom by the Company; however, we did review drafts thereof prior to their respective filings with the Commission. Based on our review of the Registration Statement, the Disclosure Package, the Prospectus and the Exchange Act Documents, our investigations made in connection with the preparation of the Registration Statement, the Disclosure Package and the Prospectus (excluding in each case the Exchange Act Documents) and our participation in the conferences referred to above, (a) each of the Registration Statement, at the Effective Date (as defined below), and the Prospectus, at the time it was filed under Rule 424(b) of the rules and regulations of the Commission under the Securities Act, appeared on its face to be appropriately responsive, in all material respects, to the requirements of the Securities Act and the Trust Indenture Act and the applicable rules and regulations of the Commission under such Acts and that each Exchange Act Document, at the time it was filed under the Exchange Act, appeared on its face to be appropriately responsive, in all material respects, to the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no opinion with respect to the financial statements or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Prospectus or the Exchange Act Documents (including the financial statements and reports described therein under “Experts”), and (b) we have no reason to believe that (i) the Registration Statement (including the information deemed to be a part of the Registration Statement pursuant to Rule 430B(f) under the Securities Act), at the Effective Date and when read together with the Exchange Act Documents, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Disclosure Package, at the Initial Sale Time (as defined below) and when read together with the Exchange Act Documents, included any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, at its date or the date hereof and in each case when read together with the Exchange Act Documents, included or includes any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading, except that in each case we express no opinion or belief with respect to the financial statement or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Prospectus or the Exchange Act Documents (including the financial statements and reports described therein under “Experts”). For purposes of this paragraph, (A) “Effective Date” means, in the case of clause (a) above, the date the Annual Report was filed by

A-4

the Company under the Exchange Act and, in the case of clause (b) above, the most recent effective date of the Registration Statement determined pursuant to Rule 430B(f)(2) under the Securities Act and (B) “Initial Sale Time” means 4:30 p.m., New York City time, on the date of the Underwriting Agreement.

We are members of the Bar of the State of New York and we do not express any opinion herein concerning any law other than the law of the State of New York, the Federal law of the United States and, to the extent set forth herein, the law of the State of New Jersey. Insofar as the opinions expressed herein relate to or are dependent upon matters governed by the laws of the State of New Jersey, we have relied upon the opinion letter of ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ PC referred to above, and to such extent our opinions herein are subject to the same assumptions, qualifications, exceptions and limitations provided for in such opinion letter.

This opinion is rendered to you for your benefit and the benefit of the other Underwriters in connection with the transaction contemplated by the Underwriting Agreement. This opinion may not be relied upon by you or any of the other Underwriters for any other purpose, or relied upon by, or furnished to, any other person, firm or corporation without our prior written consent.

Very truly yours,

A-5

▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

We have acted as special New Jersey counsel for National Fuel Gas Company, a New Jersey corporation (the “Company”), in connection with the sale by the Company to you of a $500,000,000 aggregate principal amount of the Company’s 4.90% Notes due 2021 (the “Notes”). This opinion is being rendered to you at the Company’s request pursuant to Section 6(e)(ii) of the Underwriting Agreement dated November 28, 2011 between the Company and the Underwriters named therein (the “Underwriters”), for whom you are acting as Representatives (the “Agreement”). Our role in this transaction is limited to rendering this letter. We are not familiar with the general business affairs of the Company (other than the organizational documents referred to herein) and have not been involved in the negotiation or closing of the transactions that are the subject of this letter. For purposes of our opinions set forth herein, we have assumed, with your consent and without investigation, the correctness and accuracy of the opinions, dated this same date, of ▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP.

In connection with rendering this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, agreements, certificates of public officials and other instruments and reviewed such questions of law as we have deemed necessary or appropriate for the purposes of this opinion, including the following documents:

B-1

(a) the Company’s Registration Statement on Form S-3 (File No. 333-158060) under the Securities Act of 1933, as amended (the “Securities Act”);

(b) the Company’s Prospectus dated March 17, 2009, as supplemented by each of (i) the Preliminary Prospectus Supplement, Subject to Completion, dated November 28, 2011 (such Prospectus, as so supplemented, the “Preliminary Prospectus”) and (ii) the Prospectus Supplement dated November 28, 2011 (such Prospectus, as so supplemented, the “Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange Commission under the Securities Act;

(d) the Indenture, dated as of October 1, 1999, including the Officer’s Certificate, dated December 1, 2011, establishing the terms of the Notes (the “Indenture”) between the Company and The Bank of New York Mellon (formerly The Bank of New York), as Trustee (the “Trustee”);

(e) the Notes;

(f) the certificate of the Secretary of the Company dated as of even date herewith (the “Secretary’s Certificate”);

(g) the Restated Certificate of Incorporation of the Company dated September 21, 1998, as amended by that certain Certificate of Amendment dated March 14, 2005 (the “Charter”);

(h) the Bylaws of the Company as restated on June 11, 2008 (the “Bylaws”); and

(i) a certificate of good standing relating to the Company from the New Jersey State Treasurer dated November 22, 2011.

In connection with rendering this opinion, we have also examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. The Agreement and the Indenture are referred to herein collectively as the “Transaction Agreements.”

Upon the basis of such examination and subject to each of the qualifications referred to herein, we advise you that, in our opinion:

(i) The Company is a corporation duly incorporated and validly existing under the laws of the State of New Jersey, with corporate power and authority to own its properties and conduct its business as described in the Preliminary Prospectus and the Prospectus.

(ii) The Indenture pursuant to which the Notes are being issued has been duly authorized, executed and delivered by the Company.

B-2

(iii) The Notes have been duly authorized, executed and delivered by the Company and constitute the valid obligations of the Company to the extent that the laws of the State of New Jersey are applicable.

(iv) The use of facsimile signatures of officers of the Company upon the Notes has been duly authorized and is valid under the laws of the State of New Jersey.

(v) The Agreement has been duly authorized, executed and delivered by the Company.

(vi) The consummation of the transactions pursuant to the terms of the Transaction Agreements and the fulfillment of the terms thereof will not result in a breach of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, (A) the Charter or the By-Laws or (B) insofar as the laws of the State of New Jersey apply, any law, order, rule or regulation applicable to the Company of any New Jersey court or governmental body having jurisdiction over the Company or its properties.

(vii) There are no approvals or consents of, or registrations or filings with, any governmental body, insofar as the laws of the State of New Jersey apply, legally required for the issuance and sale of the Notes by the Company pursuant to the terms of the Transaction Agreements, except for such approvals, consents, registrations or filings as may be required under state securities or “blue sky” laws.

Our opinions are qualified by, and we render no opinion with respect to, the applicability of state securities or “blue sky” laws, including, without limitation, the New Jersey Uniform Securities Law, as amended, to the proposed issuance and sale of the Notes by the Company or to any distribution thereof by you.

This opinion is subject to (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or any comparable provision of state law and other laws of general application affecting the rights and remedies of creditors and (ii) general principles of equity. None of our opinions cover or otherwise address any of the following laws, statutes or regulations or legal issues: (i) laws, statutes and regulations that prohibit or limit the validity or enforceability of obligations based on attributes of the party seeking enforcement and (ii) usury law, statutes and regulations. In rendering the opinion set forth in paragraph (ii) above on due execution and delivery of the Indenture dated as of October 1, 1999, we are relying solely upon a certificate of an officer of the Company. In rendering the opinion set forth in paragraph (iv) above, we express no opinion as to the effect of the use of facsimile signatures of officers of the Company upon the negotiability of the Notes.

This opinion letter is based upon the customary practice of lawyers who regularly give, and lawyers who regularly advise opinion recipients regarding, opinions of the kind rendered in this opinion letter. The opinions expressed herein are subject to the assumptions, exceptions, limitations, qualifications and comments set forth herein.

The opinions expressed herein relate only to laws that are specifically referred to in this letter and to which, in our experience, are normally applicable to transactions of the type

B-3

contemplated by the Transaction Agreements. We have not undertaken any research for purposes of determining whether any parties to any agreement or any of the transactions that may occur in connection with the Transaction Agreements are subject to any law or other governmental requirement that is not generally applicable to transactions of the type provided for in the Transaction Agreements.

In rendering this opinion, we have, with your approval, relied without independent verification on (i) information obtained from public officials and officers of the Company and (ii) factual information provided to us in certificates signed by officers of the Company and in the representations and warranties in the Transaction Agreements. We have assumed without investigation that the information upon which we have relied is accurate and does not omit disclosures necessary to prevent such information from being misleading. With respect to each of the Transaction Agreements and the Notes, we have assumed that such agreement or Note was duly authorized, executed and delivered by each party thereto other than the Company, that such Note has been paid for by you in accordance with the terms of the Agreement, that each of the Transaction Agreements and the Notes constitute the binding obligation of each party thereto, including the Company, enforceable against each such party, including the Company, in accordance with its terms, and that no party other than the Company will take in the future any discretionary action (including a decision not to act) permitted (but not expressly contemplated or mandated) under the Transaction Agreements that would result in a violation of law or constitute a breach or default under any other agreements or court orders to which such party may be subject. We have also assumed the due authentication and delivery of the Notes by the Trustee in accordance with the requirements of the Indenture, that no agreement of the Company prohibits or limits the Company’s ability to issue the Notes, that there has not been any mutual mistake of fact, fraud, duress or undue influence and there are no agreements or understandings among the parties, written or oral, and there is no usage of trade or course of dealing among the parties that would, in any case, define, supplement or qualify the terms of any of the Transaction Agreements. We have relied, without investigation, upon the assumption that all information required to be disclosed in connection with any consent or approval by the Company’s board of directors and all other information required to be disclosed to such parties in connection with any issue relevant to our opinions, has in fact been fully and fairly disclosed to all persons to whom it is required to be disclosed.

We have further assumed the legal capacity of all natural persons, the genuineness of all signatures, that each signatory to each Transaction Agreement and Note is the individual identified as such signatory below his or her signature, the authenticity of all documents submitted to us as originals, the conformity to original documents of documents submitted to us as certified, facsimile, conformed, electronic or photostatic copies and the authenticity of the originals of such copies. In rendering the opinions set forth in paragraph (i) above, we have relied on a recently dated certificate of a public official and our opinion in that paragraph is given solely as of the date and time of such certificate. Our opinion regarding court orders set forth in clause (B) of paragraph (vi) above is limited to court orders within the actual knowledge of those attorneys in this firm who have rendered legal services to the Company, and we have not conducted a search of any electronic databases or the dockets of any court, administrative or regulatory body, agency or other filing office in any jurisdiction.

B-4

In rendering the opinions set forth in paragraphs (iii) and (v) above as to the delivery by the Company of the Notes and the Agreement, respectively, we have assumed with your permission that electronic transmission of the Agreement and the Notes has been authorized by the parties to the Agreement and the Notes for purposes of delivery.

Each opinion set forth in this letter represents our opinion as to how that issue would be resolved were it to be considered by the highest court of the jurisdiction upon whose law our opinion on that issue is based. The manner in which any particular issue would be treated in any actual court case would depend in part on facts and circumstances particular to the case, and this letter is not intended to guarantee the outcome of any legal dispute. We have assumed without investigation that at the time thereof the persons authorizing the transactions contemplated by the Transaction Agreements for the Company did not violate any fiduciary duty.

This opinion is limited to the laws of the State of New Jersey and we are expressing no opinion as to the effect of the laws of any other jurisdiction nor with respect to choice of laws.

This opinion is rendered to you for your benefit, the benefit of the other Underwriters and for the benefit of the Trustee in connection with the transaction contemplated by the Agreement. The Trustee is entitled to rely upon this opinion to the same extent as if the opinion had been specifically addressed and rendered to the Trustee. This opinion may not be relied upon by you, any of the other Underwriters or the Trustee for any other purpose or relied upon by, or furnished to, any person, firm or corporation without our prior written consent; provided however, that a copy of this opinion is being delivered to each of ▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, counsel for the Company, and Pillsbury ▇▇▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇▇ LLP, counsel for the Underwriters, who, in their respective opinions to you of even date herewith and, in the case of ▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, to the Trustee as well, are entitled to rely upon the opinions expressed herein concerning matters of New Jersey law to the same extent as if this opinion had been addressed to each of them. In addition, without our written consent: (i) this letter may not be cited or quoted in any financial statement, prospectus or other similar document; (ii) this letter may not be cited or quoted in any other document or communication that might encourage reliance upon this letter by any person or for any purpose excluded by the restrictions in this paragraph; and (iii) copies of this letter may not be furnished to anyone for purposes of encouraging such reliance. This opinion letter is effective only as of the date hereof and is based upon applicable laws as such laws exist on the date of this opinion. We disclaim any obligation to advise you of any developments in matters covered by this opinion letter that come to our attention after the date of this opinion letter.

Very truly yours,

Ladies and Gentlemen:

Please refer to the sale and issuance by National Fuel Gas Company (the “Company”), pursuant to the Underwriting Agreement dated November 28, 2011 between the Company and the Underwriters named therein, for whom you are acting as Representatives (the “Agreement”), of an aggregate of $500,000,000 principal amount of 4.90% Notes due 2021 (the “Notes”) being issued under the Company’s Indenture, dated as of October 1, 1999, to The Bank of New York Mellon (formerly The Bank of New York), as Trustee. I have served as General Counsel of the Company and counsel for National Fuel Gas Distribution Corporation (“Distribution”), National Fuel Gas Supply Corporation (“Supply”) and Seneca Resources Corporation (“Seneca” and, together with Distribution and Supply, the “Subsidiaries”), each of which is a wholly owned subsidiary of the Company. I am a member of the New York Bar and I am familiar with the litigation to which the Subsidiaries are parties, with their respective corporate records and with the minutes of their respective Boards of Directors. This opinion is being rendered to you at the Company’s request pursuant to Section 6(e)(iii) of the Agreement.

Based upon the foregoing, I am of the opinion that:

1. Supply and Seneca have been duly incorporated and are now validly existing as corporations in good standing under the laws of the Commonwealth of Pennsylvania.

C-1

2. Distribution has been duly incorporated and is now validly existing as a corporation in good standing under the laws of the State of New York.

3. Each of the Subsidiaries has full corporate power to conduct the business now being conducted by it as set forth in or incorporated by reference in the Prospectus dated March 17, 2009, as supplemented by each of the Preliminary Prospectus Supplement, Subject to Completion, dated November 28, 2011 and the Prospectus Supplement dated November 28, 2011, relating to the Notes (such Prospectus, as so supplemented, the “Preliminary Prospectus” and the “Prospectus,” respectively), and is in good standing under the laws of each other state in which such qualification is legally required, except where the failure to so qualify would not result in a material adverse change in the business, properties or financial condition of the Company and its subsidiaries considered as one enterprise (any such change is called a “Material Adverse Change”).

4. To the best of my knowledge and other than as set forth in or incorporated by reference in the Preliminary Prospectus and the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject that, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate result in a Material Adverse Change; and, to the best of my knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

5. Of the Company and the Subsidiaries, only Distribution carries on a public utility business in the State of New York or the Commonwealth of Pennsylvania. Distribution holds franchises that I consider to be adequate and sufficient to permit it to engage in the business that it presently conducts and there is no pending litigation concerning its rights to render services under any such franchise.

6. The consummation of the transactions pursuant to the terms of the Agreement and the fulfillment of the terms thereof will not result in a breach of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, (i) the Restated Certificate of Incorporation and each amendment and supplement thereof to date or the By-Laws, as amended to date, of the Company, or any material contract, agreement or other instrument to which the Company is a party or by which it may be bound or (ii) any law, order, rule or regulation applicable to the Company of any court or any federal or state governmental body having jurisdiction over the Company or its properties.

Very truly yours,

C-2
