EXHIBIT 10.2 July 14, 1997 Re: STANDBY PURCHASE COMMITMENT McMoRan Oil & Gas Co. 1615 Poydras Street New Orleans, LA 70112 ATTENTION: Mr. Richard C. Adkerson, Co-Chairman and Chief Executive Officer Mr. C. Howard Murrish, President and Chief Operating Officer Gentlemen: We understand that McMoRan Oil & Gas Co. ("MOXY") intends to distribute to holders of record of shares of its Common Stock, par value $0.01 per share ("COMMON STOCK"), transferable subscription rights (the "RIGHTS") to subscribe for and purchase additional shares of Common Stock as follows (the "RIGHTS OFFERING"): The exercise price for each Right will be $3.50 per share (the "SUBSCRIPTION PRICE"). Each holder of record of shares of Common Stock on the record date for the distribution of Rights will receive approximately 2 Rights for every share of Common Stock held. Each Right will represent the right to purchase one share of Common Stock (the "BASIC SUBSCRIPTION PRIVILEGE"). Each holder of Rights (each a "HOLDER") who elects to exercise in full the Basic Subscription Privilege may also subscribe to purchase at the Subscription Price additional shares of Common Stock available as a result of unexercised Rights, if any (the "OVERSUBSCRIPTION PRIVILEGE"). 28,571,429 shares of Common Stock will be issuable upon exercise of all of the Rights. The Rights will be transferable and will expire 30 days after issuance or on such later date as may be agreed between MOXY and FRP (such initial date or any such later date, the "EXPIRATION DATE"). The Rights and the shares of Common Stock issuable upon exercise thereof will be listed on the Nasdaq National Market ("NASDAQ"). Based on the structure of the Rights Offering described above and in consideration of the mutual representations, warranties and agreements contained herein, the parties hereto hereby agree as follows: McMoRan Oil & Gas Co. 2 July 14, 1997 1. STANDBY COMMITMENT. Upon the terms and subject to the conditions set forth herein, MOXY agrees to sell to FRP, and FRP agrees to purchase from MOXY (the "STANDBY COMMITMENT"), at the Subscription Price, all the shares of Common Stock issuable upon exercise of the Rights if and to the extent that such shares of Common Stock are not purchased by Holders pursuant to the exercise of the Rights, including the Oversubscription Privilege (such unpurchased shares being referred to as the "EXCESS SHARES"). Subject to Section 3 below, payment of the aggregate Subscription Price for the Excess Shares shall be made on the third business day following the Expiration Date (the "CLOSING DATE"), against delivery to FRP of certificates evidencing the shares of Common Stock purchased by it, in immediately available funds by wire transfer to an account of MOXY designated by MOXY by notice to FRP no later than one business day prior to the Closing Date. 2. FRP PURCHASE OPTION. (a) Promptly on or after the Expiration Date and after all prorations and adjustments contemplated by the terms of the Rights Offering shall have been effected (but in no event later than the date one business day after the Expiration Date), MOXY shall deliver, or cause the Subscription Agent (as defined in the Registration Statement) to deliver, a written notice (the "STANDBY PURCHASE NOTICE") to FRP setting forth (i) the aggregate number of Rights properly exercised by Holders pursuant to the terms of the Rights Offering; (ii) the aggregate number of Excess Shares to be purchased by FRP pursuant to its Standby Commitment (the "STANDBY PURCHASE AMOUNT"); (iii) the aggregate Subscription Price therefor; and (iv) the calculation, including reasonable details thereof, of the maximum number of Additional Shares, if any, available for purchase by FRP pursuant to the FRP Purchase Option as provided in subsection (b) below. (b) MOXY hereby grants FRP an option (the "FRP PURCHASE OPTION") to purchase, at the Subscription Price, up to such number of shares of Common Stock, if any, (the "ADDITIONAL SHARES") as shall result in FRP's owning 30% of the aggregate outstanding shares of Common Stock immediately after giving effect to such purchase and the Standby Purchase Amount. FRP may exercise the FRP Purchase Option, in whole or in part, within one business day after receiving the Standby Purchase Notice, by delivering a written notice to MOXY setting forth the number of Additional Shares it wishes to purchase pursuant to the FRP Purchase Option. Such exercise of the FRP Purchase Option shall not thereafter be revocable by FRP. The purchase of the Additional Shares pursuant to the FRP Purchase Option shall take place on the Closing Date in the same manner as the purchase of the Excess Shares pursuant to the Standby Commitment as set forth in Section 1 above. McMoRan Oil & Gas Co. 3 July 14, 1997 3. STANDBY COMMITMENT FEE. As compensation to FRP for its Standby Commitment and its obligations under the Master Agreement (including but not limited to its purchase of the MCN Properties as described therein), MOXY agrees to pay to FRP on the Closing Date a standby commitment fee of $6,000,000 (the "STANDBY COMMITMENT FEE"), irrespective of the number of shares of Common Stock purchased by FRP hereunder. The Standby Commitment Fee will at FRP's option (designated no more than one business day prior to the Closing Date) be (a) credited in whole or in part against the purchase price to be paid by FRP in connection with its purchase of the Excess Shares or the Additional Shares, if any, or both hereunder or (b) payable in immediately available funds by wire transfer to an account of FRP designated by FRP. 4. REPRESENTATIONS AND WARRANTIES OF MOXY.

INDEMNIFICATION; SURVIVAL. (a) MOXY agrees to indemnify and hold harmless FRP, its officers, directors, agents and affiliates and each person, if any, who controls FRP within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments (collectively, "LOSSES") (i) arising out of any misrepresentation or breach of warranty, covenant or agreement made or to be performed by MOXY pursuant to this letter agreement or (ii) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus or any other document, including but not limited to the proxy statement, filed by MOXY with the McMoRan Oil & Gas Co. 6 July 14, 1997 Commission in connection with the transactions contemplated hereby and by the Registration Statement (collectively, the "SEC DOCUMENTS"), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such Losses are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to FRP furnished in writing to MOXY by or on behalf of FRP expressly for use therein. (b) FRP agrees to indemnify and hold harmless MOXY, its officers, directors, agents and affiliates and each person controlling MOXY within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from MOXY to FRP, but only with respect to (i) any misrepresentation or breach of warranty, covenant or agreement made or to be performed by FRP pursuant to this letter agreement or (ii) information relating to FRP furnished in writing to MOXY by or on behalf of FRP expressly for use in the SEC Documents. (c) If the foregoing indemnification is unavailable to an indemnified party in respect of any Losses, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses (i) in such proportion as is appropriate to reflect the relative benefits received by MOXY on the one hand and FRP on the other hand from the Rights Offering or (ii) if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of MOXY and FRP in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. The relative benefits received by MOXY and FRP shall be deemed to be in the same proportion as the total net proceeds from the Rights Offering (before deducting expenses) received by MOXY shall bear to the Standby Commitment Fee received by FRP hereunder. The relative fault of MOXY and FRP shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by MOXY or FRP and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. MOXY and FRP agree that it would not be just and equitable if contribution pursuant to this subsection were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. Notwithstanding the foregoing, FRP shall not be required to contribute any amount in excess of an amount equal to the Standby Commitment Fee. McMoRan Oil & Gas Co. 7 July 14, 1997 (d) The respective representations, warranties, indemnities, contribution agreements and other statements of each of the parties hereto shall remain operative and in full force and effect, and will survive delivery of and payment for the Excess Shares and the Additional Shares, if any, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of MOXY or FRP, (ii) the delivery of and payment for the Excess Shares and the Additional Shares, if any, hereunder and (iii) the termination of this letter agreement. 9.
