(vii) To the best of such counsel's knowledge, there are no contracts or other documents which are required to be described in the Prospectus or filed as exhibits to the Registration Statement by the Securities Act or by the Rules and Regulations which have not been described or filed as exhibits to the Registration Statement or incorporated therein by reference as permitted by the Rules and Regulations; (viii) This Agreement has been duly authorized, executed and delivered by the Corporation; (ix) The issue and sale of the shares of Stock being delivered on such Delivery Date by the Corporation and the compliance by the Corporation with all of the provisions of this Agreement and the consummation of the transactions contemplated hereby will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel to which the Corporation or the Designated Subsidiary is a party or by which the Corporation or the Designated Subsidiary is bound or to which any of the property or assets of the Corporation or the Designated Subsidiary is subject, nor will such actions result in any violation of the provisions of the charter or by-laws of the Corporation or the Designated Subsidiary or any U.S. statute or any order, rule or regulation known to such counsel of any U.S. court or U.S. governmental agency or body having jurisdiction over the Corporation or the Designated Subsidiary or any of their properties; and, except for the registration of the Stock under the Securities Act and such consents, approvals, authorizations, registrations or qualifications which have already been obtained by the Corporation or as may be required under the Exchange Act and applicable state securities laws in connection with the purchase and distribution of the Stock by the Underwriters, no consent, approval, authorization or order of, or filing or registration with, any such court or governmental agency or body is required for the execution, delivery and performance of this Agreement by the Corporation and the consummation of the transactions contemplated hereby; and (x) To the best of such counsel's knowledge, other than with respect to the Corporation's outstanding convertible debentures and unsecured senior notes due 1996 and the Restated Rights Agreement, there are no contracts, agreements or understandings between the Corporation and any person granting such person the right to require the Corporation to file a registration statement under the Securities Act with respect to any securities of the Corporation owned or to be owned by such person or to require the Corporation to include such 11 securities in the securities registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Corporation under the Securities Act. In rendering such opinion, such counsel may state that his opinion is limited to matters governed by the Federal laws of the United States of America, the laws of the State of Ohio and the General Corporation Law of the State of Delaware and that such counsel is not admitted in the State of Delaware. Such counsel shall also have furnished to the Representatives a written statement, addressed to the Underwriters and dated such Delivery Date, in form and substance satisfactory to the Representatives, to the effect that (x) such counsel is General Counsel of the Corporation and supervises attorneys in the Law Department of the Corporation who have acted as counsel to the Corporation in connection with the preparation of the Registration Statement, and (y) based on the foregoing, no facts have come to the attention of such counsel or the attorneys who he supervises which lead him or any of them to believe that (I) the Registration Statement, as of the Effective Date, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus contains any untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading or (II) any document incorporated by reference in the Prospectus or any further amendment or supplement to any such incorporated document made by the Corporation prior to such Delivery Date, when they became effective or were filed with the Commission, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (in each case, other than the financial statements and related schedules thereto, as to which such counsel need express no belief). (e) J.T. Mills, Vice-President-Taxes of the Corporation, shall have furnished to the Representatives a letter, addressed to the Underwriters and dated such Delivery Date, in form and substance satisfactory to the Representatives, to the effect that such counsel has reviewed the statements in the Prospectus under the caption "Certain United States Tax Consequences to Non-United States Holders" and, insofar as they are, or refer to, statements of United States law or legal conclusions, such statements are accurate in all material respects. (f) Simpson Thacher & Bartlett, counsel to the Underwriters, shall have furnished to the Representatives their opinion, addressed to the Underwriters and dated such Delivery Date, in form and substance satisfactory to the Representatives, to the effect that: (i) The Corporation has been duly incorporated and is validly existing and in good standing under the laws of the State of Delaware; (ii) The shares of Stock being delivered on such Delivery Date have been duly authorized by the Corporation and, upon payment and delivery in accordance with the terms hereof, will be validly issued, fully paid and non-assessable; (iii) The statements made in the Prospectus under the caption "Description of Capital Stock," insofar as they purport to constitute summaries of the terms of the Corporation's capital stock (including the Stock), constitute accurate summaries of the terms of the capital stock in all material respects; and (iv) This Agreement has been duly authorized, executed and delivered by the Corporation. 12 In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the Federal laws of the United States of America, the laws of the State of New York and the General Corporation Law of the State of Delaware and that such counsel is not admitted in the State of Delaware. Such counsel shall also have furnished to the Representatives a written statement, addressed to the Underwriters and dated such Delivery Date, in form and substance satisfactory to the Representatives, to the effect that (x) in the course of the preparation by the Corporation of the Prospectus Supplement dated the date hereof relating to the Stock (excluding the documents incorporated by reference therein), such counsel participated in conferences with certain officers and employees of the Corporation and with representatives of Price Waterhouse and (y) based upon its examination of the Registration Statement, the Prospectus and the documents incorporated by reference therein, its investigations made in connection with the preparation of such Prospectus Supplement (excluding the documents incorporated by reference therein) and its participation in the conferences referred to therein, (i) it is of the opinion that the Registration Statement, as of the Effective Date, and the Prospectus, as of its date, complied as to form in all material respects with the requirements of the Securities Act and the Rules and Regulations and that the documents incorporated by reference in the Prospectus (in each case, other than the financial statements and related schedules thereto, as to which such counsel need express no opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission thereunder and (ii) it has no reason to believe that the Registration Statement (including any document incorporated by reference therein), as of the Effective Date, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that the Prospectus (including any document incorporated by reference therein) contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (in each case, other than the financial statements and related schedules thereto, as to which such counsel need express no belief). (g) The Corporation shall have furnished to the Representatives a letter (as used in this paragraph, the "bring-down letter") of Price Waterhouse, addressed to the Underwriters and dated such Delivery Date, (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date of the bring-down letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Prospectus, as of a date not more than five days prior to the date of the bring-down letter), the conclusions and findings of such firm with respect to the financial information and other matters covered by its letter (the "initial letter") delivered to the Representatives concurrently with the execution of this Agreement, and as to such other matters requested by the Underwriters and (iii) confirming in all material respects the conclusions and findings set forth in the initial letter. (h) The Corporation shall have furnished to the Representatives a certificate, dated such Delivery Date, of the Chairman of its Board or a Vice President and its Executive Vice President - Accounting and Finance and Chief Financial Officer or Vice President & Comptroller stating that: (i) The representations, warranties and agreements of the Corporation in Section 1 are true and correct in all material respects as of such Delivery Date; the Corporation has complied with all its agreements contained herein; and the conditions set forth in Sections 7(a) and 7(i) have been fulfilled; and (ii) They have carefully examined the Registration Statement and the Prospectus and, in their opinion (A) as of the Effective Date, the Registration Statement and Prospectus did not 13 include any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and (B) since the Effective Date, no event has occurred which has resulted in the Registration Statement and the Prospectus including an untrue statement of a material fact or omitting to state a material fact required to be stated therein or necessary to make the statements therein not misleading. (i) (i) Neither the Corporation nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Registration Statement or the Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Registration Statement and the Prospectus or (ii) since such date there shall not have been any change in the capital stock or long-term debt of the Corporation or any of its subsidiaries or any change, or any development likely to involve a prospective change, in or affecting the management, consolidated financial position, stockholders' equity or results of operations of the Corporation and its subsidiaries or the financial position, stockholders' equity or results of operations of the U.S. Steel Group, otherwise than as set forth or contemplated in the Registration Statement and the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Stock being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus. (j) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the over-the-counter market, or in the Steel Stock, shall have been suspended or minimum prices shall have been established on one or more of such exchanges or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by United States federal or New York state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (iv) there shall have occurred either (A) any outbreak of hostilities or an escalation of hostilities or a declaration of a national emergency or war or (B) such a material adverse change in national or international economic, political or financial conditions, national or international equity markets or currency exchange rates or controls as to make it, in either case, in the judgment of a majority in interest of the several Underwriters, inadvisable or impractical to proceed with the payment for and delivery of the Stock. All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriters. 8. Indemnification and Contribution. (a) The Corporation shall indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which that Underwriter or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Underwriter and each such controlling person for any legal or other expenses reasonably incurred by that Underwriter or controlling person in connection with investigating or defending or preparing to defend against any 14 such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Corporation shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any such amendment or supplement in reliance upon and in conformity with written information furnished to the Corporation through the Representatives by or on behalf of any Underwriter specifically for inclusion therein. The foregoing indemnity agreement is in addition to any liability which the Corporation may otherwise have to any Underwriter or to any controlling person of that Underwriter. (b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Corporation, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Corporation within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Corporation or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Corporation through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, and shall reimburse the Corporation and any such director, officer or controlling person for any legal or other expenses reasonably incurred by the Corporation or any such director, officer or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Corporation or any such director, officer or controlling person. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, any indemnified party shall have the right to employ separate 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 thereof has been specifically authorized by the indemnifying party in writing, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified 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 reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties, which firm shall be designated in writing by the Representatives, if the indemnified parties under this Section 8 consist 15 of any Underwriter or any of their respective controlling persons, or by the Corporation, if the indemnified parties under this Section 8 consist of the Corporation or any of the Corporation's directors, officers or controlling persons. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. (d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Corporation on the one hand and the Underwriters on the other from the offering of the Stock or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Corporation on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Corporation on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this agreement (before deducting expenses) received by the Corporation bear to the total underwriting discounts and commissions received by the Underwriters with respect to the shares of the Stock purchased under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the 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 Corporation or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Corporation and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Stock underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any 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 as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint. (e) The Underwriters severally confirm that the statements with respect to the public offering of the Stock set forth on the cover page of, and under the caption "Underwriting" in, the Prospectus are correct and constitute the only information furnished in writing to the Corporation by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus. (f) The agreements contained in this Section 8 and the representations, warranties and agreements of the Corporation in Sections 1, 5 and 6 shall survive the delivery of the Stock and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 16 9. Defaulting Underwriters. If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Stock which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares of the Firm Stock set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of shares of the Firm Stock set opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such Delivery Date if the total number of shares of the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Stock to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Stock which it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. The respective purchase obligations of the non- defaulting Underwriters shall be rounded among the non-defaulting Underwriters to avoid fractional shares, as the Representatives shall determine. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives and the Corporation who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Stock to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives and the Corporation do not elect to purchase the shares which the defaulting Underwriter or Underwriters agreed but failed to purchase, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Corporation, except that the Corporation will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Corporation for damages caused by its default. If other underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Representatives or the Corporation may postpone the First Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Corporation or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement. 10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives, in their absolute discretion, by notice given to and received by the Corporation prior to delivery of any payment for the Firm Stock if, prior to that time, any of the events described in Sections 7(i) or 7(j) shall have occurred. 11. Reimbursement of Underwriters' Expenses. If (a) the Corporation shall fail to tender the Stock for delivery to the Underwriters for any reason permitted under this Agreement or (b) the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement (including the termination of this Agreement pursuant to Section 10), the Corporation shall reimburse the Underwriters for the reasonable fees and expenses of their counsel and for such other out-of-pocket expenses as shall have been reasonably incurred by them in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Corporation shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Corporation shall not be obligated to reimburse any defaulting Underwriter on account of those expenses. 12. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and: (a) if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to Morgan Stanley & Co. Incorporated, 1251 Avenue of the Americas, New York, New York 10020 Attention: Legal Department, Telephone: (212)703-4000 Facsimile: (212)703-6503; 17 (b) if to the Corporation, shall be delivered or sent by mail, telex or facsimile transmission to the address of the Corporation set forth in the Registration Statement, Attention: Dan D.

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Corporation shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters by Morgan Stanley & Co. Incorporated on behalf of the Representatives. 13. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Corporation and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Corporation contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act who offers or sells any shares of Steel Stock in accordance with the terms of the Agreement between Underwriters and (B) the indemnity agreement of the Underwriters contained in Section 8(b) of this Agreement shall be deemed to be for the benefit of directors of the Corporation, officers of the Corporation who have signed the Registration Statement and any person controlling the Corporation within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 13, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. 14. Definition of the Terms "Business Day," "Subsidiary" and "Designated Subsidiary." For purposes of this Agreement, (a) "business day" means any day on which the New York Stock Exchange, Inc. is open for trading, other than a day on which banks are authorized or obligated by law or executive order to close in New York City, (b) "subsidiary" has the meaning set forth in Rule 405 of the Rules and Regulations and (c) "Designated Subsidiary" means Marathon Oil Company. 15. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF NEW YORK. 16. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one or more counterparts, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument. 17.
