EXPLANATORY NOTE

As previously announced, on December 5, 2012 McMoRan Exploration Co. (the Company) entered into an agreement and plan of merger (the Merger Agreement), by and among, the Company, Freeport-McMoRan
Copper & Gold Inc. (FCX), and INAVN Corp., a wholly-owned subsidiary of FCX (Merger Sub), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving the merger as a wholly-owned subsidiary of FCX. The
Merger Agreement has been approved by each of the Companys and FCXs board of directors. In light of the pending acquisition, the Company does not anticipate holding an annual meeting of stockholders in 2013.

This Amendment No. 1 on Form 10-K/A (the Amendment) amends the Companys Annual Report on Form 10-K for the fiscal year ended December 31,
2012, originally filed with the Securities and Exchange Commission (the SEC) on February 22, 2013 (the Form 10-K). The Company is filing this Amendment to include the information required by and not included in Part III of the Form 10-K
because, as a result of the anticipated closing of the pending acquisition in the second quarter of 2013, the Company no longer intends to file its definitive proxy statement within 120 days of the end of its fiscal year ended December 31,
2012. There are no other changes to the Form 10-K. As a result of this Amendment, Part IV of the Form 10-K is being amended solely to add as exhibits certain new certifications in accordance with Rule 13a-14(a) promulgated by the SEC under the
Securities Exchange Act of 1934, as amended, with paragraphs 3, 4 and 5 omitted since no financial statements are contained within this Amendment. Because no financial statements are contained within this Amendment, the Company also is not including
certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 nor any disclosure with respect to Items 307 or 308 of Regulation S-K.

Except as otherwise expressly stated herein, this Amendment does not reflect events occurring after the date of the Form 10-K nor does it modify or update the disclosure contained in the Form 10-K in any
way other than as required to reflect the amendments to Part III discussed above and reflected below. Accordingly, this Amendment should be read in conjunction with the Form 10-K and the Companys other filings made with the SEC on or
subsequent to the filing of the Form 10-K on February 22, 2013.

As used in this Amendment, when the Company refers to us,
we, our, ours, the company, or MMR, the Company is describing McMoRan Exploration Co. and/or its subsidiaries.

PART III

Item 10. Directors, Executive Officers and Corporate Governance.

The information required by Item 10 regarding our executive officers appeared in a separately captioned heading after Item 4 in
Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 filed with the SEC on February 22, 2013, which information is incorporated herein by reference.

Information About Directors

The table below provides certain information
as of April 15, 2013 with respect to each of our directors. The biographies of the directors below contain information regarding the persons service as a director, business experience, director positions with other public companies held
currently or at any time during the last five years, and the experiences, qualifications, attributes or skills of such director. Unless otherwise indicated, each person has been engaged in the principal occupation shown for the past five years. The
year first elected a director and positions with the company described below include the period that the person served as a director of McMoRan Oil & Gas Co., a predecessor of the company formed in 1994. Each director was elected to serve a
one-year term at our 2012 annual meeting of stockholders held on June 14, 2012. In light of the pending merger with Freeport-McMoRan Copper & Gold Inc. (FCX), we do not anticipate holding an annual meeting to elect directors in
2013.

Upon completion of our acquisition of the shallow water Gulf of Mexico shelf properties, interests and assets of Plains
Exploration & Production Company (PXP) on December 30, 2010, we entered into a stockholder agreement with PXP pursuant to which, among other things, the size of our board of directors was increased from 9 to 11 members and PXP was
granted the right to nominate two individuals to serve on our board of directors as long as PXP and its affiliates beneficially own at least 10% of the issued and outstanding shares of our common stock. Pursuant to the stockholder agreement with
PXP, Messrs. Flores and Wombwell were elected directors at the 2012 annual meeting.

business operations, making him uniquely qualified to co-lead our board. In 1969, he and two associates founded McMoRan Oil & Gas Co., which developed into one of Americas leading independent oil and gas companies. In 1981, Mr. Moffett led

exploration activities leading to the discovery of major natural resource deposits throughout his business career. We benefit from his direction of our exploration programs and his detailed knowledge and perspective regarding strategic and

On May 24, 2012, the board of directors authorized a special committee of independent directors,
comprised of Messrs. Carmichael and Bush, with the power and authority to oversee the companys efforts to evaluate potential merger transactions with FCX and other companies. As previously disclosed, on December 5, 2012, we entered into
an agreement and plan of merger (the Merger Agreement), by and among the Company, FCX and INAVN Corp., a wholly-owned subsidiary of FCX (Merger Sub), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving the
merger as a wholly-owned subsidiary of FCX. The Merger Agreement has been approved by each of the Companys and FCXs board of directors.

Corporate Governance Guidelines; Ethics and Business Conduct Policy

Our
corporate governance guidelines and our ethics and business conduct policy are available atwww.mcmoran.com under Investor Center  Corporate Governance. Both are available in print upon request. Amendments to or waivers of our ethics
and business conduct policy granted to any of our directors or executive officers will be published promptly on our web site.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers and persons who own more than 10% of our common stock to file reports of ownership and
changes in ownership with the SEC. Based solely upon our review of the Forms 3, 4 and 5 filed during 2012, and written representations from certain reporting persons that no Forms 5 were required, we believe that all required reports were timely
filed.

Audit Committee Independence and Financial Experts

Our Board has certain standing committees, including our audit committee. Messrs. Carmichael, Day (chairman), Ford and Graham and Ms. Mestayer are the members of our audit committee. Our board has
determined that each of the members of the audit committee has no material relationship with the company and satisfies the independence criteria (including the enhanced criteria with respect to members of the audit committee) set forth in the
applicable NYSE listing standards and SEC rules. In addition, our board has determined that each member of the audit committee, Messrs. Carmichael, Day, Ford and Graham and Ms. Mestayer, qualifies as an audit committee financial
expert, as such term is defined by the rules of the SEC.

Item 11. Executive Compensation.

Executive Officer Compensation

Compensation Discussion and Analysis

This Compensation Discussion and
Analysis, or CD&A, describes and analyzes our executive compensation philosophy and program in the context of the compensation paid during the last fiscal year to our chief executive officer, our chief financial officer, and each of our two
other executive officers (our named executive officers). For fiscal 2012, our named executive officers are:



| |  |  | James R. Moffett, our co-chairman of the board, president and chief executive officer;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | Richard C. Adkerson, our co-chairman of the board;

| | - |  | ----------------------------------------------------------------------------------------



| |  |  | Kathleen L. Quirk, our senior vice president and treasurer.
| | - |  | -----------------------------------------------------------

In this CD&A, we first provide an Executive Summary of our actions and highlights from 2012. We next explain our leadership structure, the principles that guide our corporate personnel
committees (the committee) executive compensation decisions and the process we follow when setting executive compensation. Finally, we discuss in detail each component of executive compensation, including the actual results yielded for each
named executive officer for fiscal 2012.

Executive Summary

We are an entrepreneurially managed company, and our executive compensation practices reflect this philosophy. Our business focus is on high risk, high reward exploration opportunities, which is mirrored
in our executive compensation program that provides for high risk, high reward earning opportunities. We seek to closely align the interests of our named executive officers with the interests of our stockholders through the use of performance-based
compensation that balances rewards for both short- and long-term results. The primary objectives of our compensation program are to attract and retain executives, to motivate them to implement our business strategies, and to reward those executives
for successful performance. Our compensation program is designed to create an energetic environment in which the named executive officers are enthusiastic about and committed to our company and its objectives, and are working toward the successful
long-term performance of the company. The compensation program for our named executive officers is bifurcated, being comprised solely of long-term incentive awards in the form of stock options for three of our executives, and comprised of a mix of
base salary, annual cash incentive awards and long-term incentive awards for our other executive officer.

As previously
announced, on December 5, 2012, we entered into a Merger Agreement with FCX and Merger Sub, pursuant to which Merger Sub will merge with and into our Company, with the Company surviving the merger as a wholly owned subsidiary of FCX. The Merger
Agreement has been approved by each of the Companys and FCXs board of directors. In connection with the pending acquisition, which is expected to close in the second quarter of 2013, each of our executive officers has agreed to waive his
or her contractual rights to accelerated vesting of outstanding equity awards. In addition, the committees recent compensation decisions factored in the pending acquisition, in that no stock options were awarded to Messrs. Moffett and Adkerson
and Ms. Quirk in early 2013 and the stock options awarded to Ms. Parmelee do not vest upon the pending acquisition.

2012 Company Highlights

We are engaged in the exploration, development and production of oil and natural gas in the shallow waters of the Gulf of Mexico and onshore in the Gulf Coast area of the United States. Our exploration
strategy is focused on targeting large structures on the deep gas play and on the ultra-deep play. As described in Managements Discussion and Analysis of Financial Conditions and Results of Operations in our
Annual Report on Form 10-K for fiscal year 2012, we experienced significant operational and strategic accomplishments during 2012.

Leadership

Our company is managed jointly by Mr. Moffett, who
serves as our co-chairman of the board, president and chief executive officer, and Mr. Adkerson, who serves as co-chairman of the board. Messrs. Moffett and Adkerson develop the companys business strategy, but each concentrates on a
different aspect of our operations and development. Mr. Moffett directs the companys exploration and development activities, and as president and chief executive officer, he is also responsible for ensuring that the business strategy is
appropriately executed by the management team. Mr. Adkerson primarily focuses on financial strategy and planning and on administrative activities.

Setting Compensation Levels

Levels reflect company performance
and position  The committee does not apply hard metrics to its decisions regarding executive compensation. The committees decisions regarding salary levels, bonus awards, and equity grant amounts (made in the form of
stock options) for 2012 reflect the committees views as to the broad scope of responsibilities of our executive officers and the committees subjective assessment of our executives contribution to the companys overall success.

Reduction of cash outlay  The structure of our executive compensation program
also supports our companys view that compensation for our most senior executives should be closely tied to the creation of stockholder value and that such compensation should be designed to minimize cash requirements, a consideration that has
become even more critical in light of recent market conditions. In connection with our efforts to reduce overhead cash requirements, Messrs. Moffett and Adkerson, since 2002, and Ms. Quirk, since 2007, have agreed to forego all cash
compensation in exchange for special annual stock option grants, as discussed under Stock Options. We recognize that our business focus is high risk, high reward exploration opportunities, and we do not believe our practice of providing
solely equity-based compensation to a limited group of executives promotes risk-taking by these executives beyond what we believe is appropriate in terms of our business model. These executives, particularly Messrs. Moffett and Adkerson, have
significant stock holdings and have shown their longstanding commitment to increase their holdings. In addition, each of these executives has other sources of income. With respect to our other named executive officer and other key employees, the
committee believes that our balance of annual and long-term compensation elements, and our use of stock options as a long-term performance vehicle, result in a compensation program that aligns our executives and employees interests with
those of our stockholders and does not promote excessive risk-taking on the part of our executive or other employees.

Evaluation of stock option gains  The committee does not factor into its executive compensation decisions the gains received
by our executive officers in connection with the exercise of stock options. The value of stock options upon exercise is directly related to the appreciation in value of our common stock, which in turn we believe is directly affected by the efforts
of our executive officers in managing our company. Many of the stock options received by Messrs. Moffett and Adkerson and Ms. Quirk were received in lieu of cash compensation (see footnote 3 to the Outstanding Equity Awards at
December 31, 2012 table for more information). Because each undertakes a certain degree of risk and uncertainty in accepting a variable, performance-dependent award instead of cash, we believe it would be inappropriate to have the value
of those awards upon exercise affect future compensation decisions. Further, a key purpose served by granting stock options to executives is to provide an incentive for them to manage the company in a way that focuses on increasing stockholder value
over time. Accordingly, the committee has not taken realized gains on option exercises into account when making decisions regarding future compensation.

Evaluation of Peers and Process

The design of our 2012 compensation
program remains a product of a comprehensive analysis performed in 2004. The committee has not formally evaluated peer companies until recently. In addition, the committee has not referred to benchmarks in order to set executive compensation levels
or structures. We believe we are aware of and understand the compensation practices of our industry and the companies we compete with for talent, and have maintained an executive compensation program providing consistent levels and forms of
compensation from year to year targeted to maintain and attract a talented executive team. Further, we believe our program supports our core compensation goals by linking a majority of executive compensation to company performance, both long-term
and short-term, and provides a level of total compensation to each of our named executive officers that continues to be reasonable and appropriate. Also, considering that approximately 75% of votes cast on our 2012 say on pay proposal
were favorable, we believe our stockholders support our current program.

The committee consults with our co-chairmen of the
board when reviewing the performance of and determining compensation for our executive officers other than our co-chairmen themselves. In addition, the committee has engaged the services of Frederic W. Cook and Co., Inc. (formerly Cogent
Compensation Partners until their acquisition by Frederic W. Cook and Co., Inc. during 2012, and referred to herein as Cook or Cogent, as appropriate) to provide executive compensation consulting services since March 2010. Pursuant to the terms of
the engagement, Cook will not provide, and has not provided, services to the companys management without the committees prior approval. As required by SEC rules, the committee has assessed the independence of Cook and concluded that
Cooks work did not raise any conflicts of interest. In December 2010, Cogent commenced a competitive review of our executive compensation practices and reported its results to the committee in February 2011. Cogent compared our executive
compensation levels with those of the following ten peer companies: Noble Energy, Inc., Newfield Exploration Company, Plains Exploration & Production Company, Stone Energy Corporation, W&T Offshore, Inc., Energy XXI Ltd., ATP
Oil & Gas Corporation, Venoco, Inc., Energy Partners, Ltd., and Contango Oil & Gas Company. The committee used this report to evaluate whether our compensation levels were within industry norms. Based on its review, Cogent reported
that the companys total executive pay levels are within the market range (with total direct compensation below the market median and long-term incentives near the median), and are consistent with the levels found in other entrepreneurial
companies.

Components of Executive Compensation

Messrs. Moffett and Adkerson and Mses. Parmelee and Quirk provide services to the company through a services agreement between FM Services
Company and the company, as discussed below in Certain Transactions. Executive officer compensation for 2012 for Messrs. Moffett and Adkerson and Ms. Quirk consisted solely of awards of stock options, and for Ms. Parmelee
included base salary, an annual incentive award and stock options. We also provided Ms. Parmelee certain post-employment benefits and to a limited degree, certain perquisites described below, and she participated in benefit programs generally
available to our employees, such as our ECAP and health insurance plan.

Base Salaries

Our philosophy is that base salaries, which provide fixed compensation, should meet the objective of attracting and retaining the
executive officers needed to successfully manage our business. Actual individual salary amounts reflect the committees judgment with respect to each executive officers responsibility, performance, work experience and the
individuals historical compensation. As part of their agreement with the company to forego cash compensation, Messrs. Moffett and Adkerson and Ms. Quirk did not receive salaries in 2012, receiving instead the special stock option grants
discussed in Stock Options below. With respect to our other named executive officer, our goal is to allocate more compensation to the performance-dependent elements of the total compensation package. Ms. Parmelees base salary
remained at the same level for 2011 and 2012. Effective February 1, 2013, the committee approved an approximate 3% increase to Ms. Parmelees base salary, which was in line with increases approved for other key employees.

Annual Incentive Awards

Annual cash incentives are a variable component of compensation designed to reward our executives for maximizing annual operating and financial performance. Executive officers and certain managers of the
company participate in our performance incentive awards program. Under the program, the annual award is established following the end of the fiscal year based on the participants level of responsibility after reviewing our operational and
strategic accomplishments during the year. When determining the actual amounts awarded to participants for any year, the committee makes a subjective determination after considering company performance as measured by operational and financial
accomplishments and overall market conditions. With respect to Ms. Parmelee, the committee also considers the recommendations of the co-chairmen of the board.

Of our named executive officers, only Ms. Parmelee received an annual incentive award for 2012 under our performance incentive awards program. As previously stated, Messrs. Moffett and Adkerson and
Ms. Quirk agreed to forego all cash compensation during 2012, including annual incentive awards, instead receiving special grants of stock options. For 2012, the committee reviewed our operational and strategic accomplishments during 2012, as
noted above under 2012 Company Highlights, and determined that the companys performance supported a cash incentive award to Ms. Parmelee commensurate with the award she received for 2011.

Stock Options

We grant long-term incentives in the form of stock options to the companys executive officers. Stock options are a variable component of compensation intended to provide a significant potential
value that reinforces the importance of creating value for our stockholders. The committee believes that stock options are an effective and appropriate long-term incentive for our executives in that their value is dependent on an increase in our
share price and aligns the executives interests with those of our stockholders. In February 2012, we made annual stock option grants to all of our executive officers. Stock option grant levels have been historically based upon the position and
level of responsibility of the individual, and have remained at relatively consistent levels for our named executive officers in recent years. These annual grants vest ratably on the first four anniversaries of the grant date, have a term of ten
years and an exercise price equal to the fair market value of our common stock on the grant date. We have a longstanding commitment to not reprice stock options, and, except as noted below, all of our outstanding stock option grants vest fully upon
a change in control of the company. In connection with the pending FCX acquisition, each of our executive officers has agreed to waive his or her contractual rights to accelerated vesting of outstanding equity awards. In addition, the stock options
awarded to Ms. Parmelee in early 2013 do not provide for accelerated vesting upon the FCX acquisition.

##### Table of Contents

As in past years, we also made special grants of stock options to the co-chairmen and
Ms. Quirk in lieu of their 2012 cash compensation as discussed below.

Grants in lieu of Salary to Co-Chairmen of the
Board and Ms. Quirk. Annually since 2002 for Messrs. Moffett and Adkerson and since 2007 for Ms. Quirk, each has agreed to receive a special grant of stock options in lieu of cash compensation. On February 6, 2012, the committee
granted 300,000 options to Mr. Moffett, 100,000 options to Mr. Adkerson, and 45,000 options to Ms. Quirk, each option being fully exercisable, having a term of ten years and an exercise price of $13.00, the fair market value on the
grant date. None of these executives received a base salary in 2012 or an annual incentive award from the company for 2012. Although the number of options granted to each of these executives in connection with their agreements to forego cash
compensation has been relatively consistent over the last few years, the committee increased Mr. Moffetts award beginning in 2011 by 50,000 options and similarly decreased Mr. Adkersons award to reflect Mr. Moffetts
increased responsibilities as president and chief executive officer of the company. The committee continues to believe that granting a relatively consistent number of options year to year is appropriate for our program, and recognizes that this will
result in fluctuations in the grant date fair value of the awards each year as a result of changes in our stock price.

Messrs. Moffett and Adkerson and Ms. Quirk have continued their agreement to forego all cash compensation during 2013, however, in
light of the pending FCX acquisition, the committee did not grant special or annual stock option grants to these officers in early 2013.

Post-Employment Compensation

In addition to the compensation
received by the executive officers during 2012, we provided post-employment benefits to Ms. Parmelee through an ECAP, which is available to all qualified employees, and a severance plan generally available to all company employees. We also
provided additional post-employment benefits through a nonqualified defined contribution plan, as well as a separate supplemental retirement benefit for Ms. Parmelee. These programs are described below and in detail under the heading
Retirement Benefit Programs.

Nonqualified Defined Contribution Plan and Discontinued Defined Benefit
Program. Our nonqualified defined contribution plan provides those employees whose earnings in a prior year were in excess of dollar limit under Section 401(a)(17) of the Internal Revenue Code, including our executive officers, the ability
to defer up to 20% of their base salary after deferrals to the ECAP have ceased due to the qualified plan limits. The company makes a matching contribution equal to the participants deferrals in this plan and the ECAP (the qualified plan)
limited to 5% of the participants base salary. We do not take into account bonuses or income associated with option exercises or the vesting of RSUs when determining the companys matching contributions. The matching contribution noted
above is the same as the matching contribution in the ECAP, which provides that participants will receive a company contribution equal to 100% of the participants deferrals to the ECAP, subject to qualified plan limits. The purpose of the 5%
company contribution in our nonqualified plan is to continue the 5% contribution in the ECAP that is subject to the qualified plan limits. The nonqualified defined contribution plan is unfunded.

We had a defined benefit program in place until June 30, 2000. To compensate for the discontinuance of benefit accruals under this
plan, we decided that we prospectively would make an additional company contribution to our ECAP participants equal to 4% of each participants pensionable compensation up to the applicable IRS limits, and also an additional company
contribution of 4% of compensation in excess of such limits to participants in our nonqualified plan. Further, because participants in a pension plan accrue most of their benefits in the last 10 years of service, we decided that employees who met
certain age and service requirements as of June 30, 2000 (including Ms. Parmelee) would receive an additional 6% company contribution, for a total of 10%, to both the qualified and nonqualified plans. The purpose of the nonqualified plan
is to make total retirement benefits for our employees who earn over the qualified plan limits commensurate with those available to other employees as a percentage of pay.

Supplemental Retirement Benefit  Ms. Parmelee. We have agreed to pay Ms. Parmelee a supplemental nonqualified benefit upon her retirement. This unfunded arrangement will provide a
traditional defined benefit based upon accruals on excess compensation through 2000 when the traditional nonqualified defined benefit was frozen. This supplemental retirement benefit is intended to restore the value of her nonqualified benefits that
were modified during the four-year period preceding 2000 when we restructured our defined benefit program. The benefit under this arrangement is described under Retirement Benefit Programs below.

Perquisites and Other Personal Benefits

We also provided limited perquisites to Ms. Parmelee, primarily through our Executive Services Program. This program provide
reimbursement to Ms. Parmelee and other senior managers for personal financial and tax advice, certain long-term care insurance premiums and certain security services, but does not provide for any tax gross-ups on perquisites for our executive
officers. We continue to believe that the reimbursement for financial and tax advice historically offered under this program remain appropriate, in that they provide our key personnel with increased efficiencies in handling personal matters and
promote their focus on company business. As reflected in the Summary Compensation Table below, Ms. Parmelee is the only executive participating in this program, and the benefits she received were minimal compared to her total
compensation.

Tax Considerations

Section 162(m) of the Internal Revenue Code limits a public companys annual tax deduction to $1 million for compensation paid to certain highly compensated executive officers. Qualified
performance-based compensation is excluded from this deduction limitation if certain requirements are met. The committee considers it important to retain flexibility to design compensation programs that recognize a full range of criteria important
to our success, even where compensation payable under the programs may not be fully deductible.

The stock options granted to
our executive officers are intended to qualify for the exclusion from the deduction limitation under Section 162(m). The committee believes that the remaining components of individual executive compensation for 2012 that do not qualify for an
exclusion from Section 162(m) should not exceed $1 million and therefore should qualify for deductibility.

|(1) | Messrs. Moffett and Adkerson agreed to forego all cash compensation from the company since 2002 and Ms. Quirk agreed to forego all cash compensation from the
company since 2007, including during each of the three years ended December 31, 2012, 2011 and 2010. In lieu of cash compensation in each of 2012 and 2011, the company granted to Messrs. Moffett and Adkerson and Ms. Quirk 300,000 options,
100,000 options and 45,000 options, respectively. In lieu of cash compensation in 2010, the company granted to Messrs. Moffett and Adkerson and Ms. Quirk 250,000 options, 150,000 options and 45,000 options, respectively. For more information
see the section titled Compensation Discussion and Analysis and the tables titled Grants of Plan-Based Awards in Fiscal Year 2012 and Outstanding Equity Awards at December 31, 2012. Messrs. Moffett and
Adkerson and Messes. Parmelee and Quirk also provide services to and receive compensation from Freeport-McMoRan Copper & Gold Inc. (FCX). Ms. Parmelees compensation is paid through an allocation arrangement under a services
agreement with FM Services Company, a wholly-owned subsidiary of FCX, under which 80% of Ms. Parmelees salary is allocated to us and 20% of Ms. Parmelees salary is allocated to FCX. Accordingly, the amounts reported in the
Salary and All Other Compensation columns represent only the portion allocated to us.

|(2) | The amount reported in the Stock Awards column reflects the grant date fair value of RSUs granted to Ms. Parmelee in 2010, which are valued on the date
of grant at the closing sale price per share of our common stock.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | The amounts reported in the Option Awards column reflect the grant date fair value of the options granted to the named executive officers in the year
reflected, determined using the Black-Scholes option model. For information relating to the assumptions made by us in valuing the option awards made to our named executive officers in fiscal years 2010 through 2012, refer to Note 12 of our financial
statements in our annual report on Form 10-K for the year ended December 31, 2012. Our committee views options granted in a given year as part of the prior years compensation. For more information regarding options granted to one named
executive officer in 2013 relating to 2012 compensation, see the section titled Compensation Discussion and Analysis.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | The amounts reported in the All Other Compensation column for 2012 reflect the sum of the incremental cost to the company of all perquisites and other
personal benefits and additional all other compensation required by SEC rules to be separately quantified, including amounts contributed by the company to defined contribution plans and the dollar value of life insurance premiums paid by the
company. For Ms. Parmelee, the amounts reported for 2012 include (a) personal financial and tax advice under the companys program, (b) our premium payments for personal excess liability insurance, (c) our contributions to
defined contribution plans and (d) our premium payments for universal life insurance, as reflected in the table below.

|(1) | Unless otherwise noted, the stock options become exercisable in 25% increments over a four-year period and have a term of ten years. The stock options are immediately
exercisable in their entirety if, under certain circumstances, (a) any person or group of persons acquires beneficial ownership of shares in excess of certain thresholds; or (b) the composition of the board of directors is changed after a
tender offer, exchange offer, merger, consolidation, sale of assets or contested election or any combination of these transactions. In connection with the pending merger with FCX, Messrs. Moffett and Adkerson and Messes. Parmelee and Quirk each
waived his or her contractual right to accelerated vesting as a result of the merger. The stock options awarded to Ms. Parmelee in early 2013 do not provide for accelerated vesting as a result of the merger.

NYSE-Listed Stocks on the grant date.

became exercisable immediately upon grant and have a term of ten years.

of these transactions. In connection with the pending merger with FCX, Messrs. Moffett and Adkerson and Messes. Parmelee and Quirk each waived his or her contractual right to accelerated vesting as a result of the merger. The stock options awarded
to Ms. Parmelee in early 2013 do not provide for accelerated vesting as a result of the merger.

|(4) | Effective January 29, 2007, the corporate personnel committee of our board of directors amended its policies to provide that the exercise price of an option shall
not be less than the closing quoted per share sale price on the Composite Tape for New York Stock Exchange-Listed Stocks on the grant date or, if there are no reported sales on such date, on the last preceding date on which any reported sale
occurred. Thus, the exercise price of the stock options expiring in January 2017 and thereafter was determined by reference to the closing price of our common stock on the grant date. Prior to that time, the exercise price of each outstanding stock
option reflected in this table was determined by reference to the average of the high and low quoted per share sale price on the Composite Tape for New York Stock Exchange-Listed Stocks on the grant date or, if there are no reported sales on such
date, on the last preceding date on which any reported sale occurred.

|(5) | The market value of the unvested RSUs reflected in this table was based on the $16.05 closing market price per share of our common stock on December 31, 2012.

Retirement Benefit Programs

Nonqualified Defined Contribution Plan. We maintain an unfunded nonqualified defined contribution plan
for the benefit of our executive officers, as well as others. The plan provides those employees whose earnings in a prior year were in excess of the dollar limit under Section 401(a)(17) of the Internal Revenue Code the ability to defer up to
20% of their base salary after deferrals to the ECAP have ceased due to qualified plan limits. The

company makes a matching contribution equal to the participants deferrals in this plan and the ECAP limited to 5% of the participants base salary. In addition, the company also makes
enhanced contributions equal to a minimum of 4% of eligible compensation (base salary plus 50% of bonus) in excess of qualified plan limits for each eligible employee, with employees who met certain age and service requirements in 2000 (including
Ms. Parmelee) receiving an additional 6% contribution. Distribution is made in a lump sum as soon as practicable or, if timely elected by the participant, on January 1st of the year following retirement, but no earlier than the date
allowable under law following separation from service. The table below sets forth the unfunded balances under our nonqualified defined contribution plan as of December 31, 2012 for Ms. Parmelee. Messrs. Moffett and Adkerson and
Ms. Quirk participate in FCXs nonqualified retirement benefit plan.

Supplemental Retirement Benefit. We have agreed to pay Ms. Parmelee upon her retirement a supplemental
nonqualified benefit. This benefit will be paid out as a joint-and-50%-survivor annuity. If Ms. Parmelee had retired effective December 31, 2012, this benefit would have been $1,938 per month (which represents the 80%
portion of the benefit allocated to us).

Potential Payments upon Termination or Change of Control

In addition to the retirement benefits programs discussed above, and the benefits under the companys ECAP and severance plans, which
are available to all eligible employees, the only other post-employment benefit we provide to our executives is accelerated vesting of stock options and RSUs upon certain terminations of employment and upon a change of control. This benefit is a
term of the stock option or RSU grant, and applies to all stock option or RSU recipients, not just our executives.

Acceleration upon Change of Control. No named executive officer is entitled to any payment or accelerated benefit in
connection with a change of control, except for accelerated vesting of stock options and RSUs issued under our stock incentive plans. Pursuant to the terms of the stock option or RSU agreements, all outstanding stock options or RSUs will fully vest
upon a change of control, even if the executive remains employed. As previously disclosed, in connection with the pending merger with FCX, Messrs. Moffett and Adkerson and Messes. Parmelee and Quirk each waived his or her contractual right to
accelerated vesting as a result of the merger. The stock options awarded to Ms. Parmelee in early 2013 do not provide for accelerated vesting as a result of the merger.

Acceleration upon Death, Disability or Retirement. Pursuant to the terms of the stock option or RSU agreements, upon termination of the executives employment as a result of death,
disability or retirement, the unvested portion of any outstanding stock option or RSU that would have vested within one year of the date of termination shall vest.

The following table shows the value of stock options, and with respect to Ms. Parmelee, RSUs, that would have vested for our named executive officers as a result of a change of control (other than
the pending merger with FCX) or termination of employment as described above, assuming a December 31, 2012 termination date, and using the closing price of our common stock of $16.05 (as reported on the New York Stock Exchange on
December 31, 2012).

Director Compensation

We use a combination of cash and equity-based incentive compensation to attract and retain qualified candidates to serve on our board of
directors. In setting director compensation, we consider the significant amount of time directors dedicate in fulfilling their duties as directors as well as the skill-level required by the company to be an effective member of our board of
directors. The form and amount of director compensation is reviewed by our nominating and corporate governance committee, which makes recommendations to the full board of directors.

Cash Compensation

Each non-management director and advisory director
receives an annual fee of $50,000. Committee chairs receive an additional annual fee as follows: audit committee, $15,000; corporate personnel committee, $10,000; and all other committees (including nominating and corporate governance committee),
$7,500. Each non-management director and each advisory director receives a fee of $2,000 for attending each board and committee meeting (for which he or she is a member) and is reimbursed for reasonable out-of-pocket expenses incurred in attending
such meetings.

In addition, in connection with their service in 2012 on the special committee of the board, each of Messrs.
Bush and Carmichael will receive a one-time fee of $50,000 for serving on the special committee and $2,000 for attendance at each meeting of the special committee, and will be reimbursed for reasonable out-of-pocket expenses incurred in attending
such meetings, all of which are expected to be paid in 2013.

The compensation of each of Messrs. Moffett and Adkerson, the
co-chairmen of our board, is reflected in the 2012 Summary Compensation Table.

Equity-Based Compensation

During 2012, non-management directors and advisory directors also received equity-based compensation under the 2008 Stock Incentive Plan
(the Plan), which was approved by our stockholders. The Plan authorizes our nominating and corporate governance committee to make equity grants to our non-management directors and advisory directors at its discretion. Upon approval of our nominating
and corporate governance committee, each non-management director and advisory director receives an annual grant of options to acquire 10,000 shares of our common stock and 2,500 restricted stock units (RSUs) on June 1 of each year. All options
are granted at fair market value on the grant date, vest ratably over the first four anniversaries of the grant date and expire on the tenth anniversary of the grant date. The RSUs also vest ratably over the first four anniversaries of the grant
date. Each RSU entitles the director to receive one share of our common stock upon vesting. To the extent dividends are paid on our common stock in the future, dividend equivalents will accrue on the RSUs on the same basis as dividends will be paid
on our common stock and will include market rate interest. The dividend equivalents will only be paid upon vesting of the shares of our common stock. Our program also provides for a pro rata grant of options to a director upon his or her initial
election to our board of directors other than at an annual meeting.

On June 1, 2012, each non-management director and
advisory director was granted an option to purchase 10,000 shares of our common stock with an exercise price of $8.82 and 2,500 RSUs.

##### Table of Contents

Non-management directors may elect to exchange all or a portion of their annual fee for an
equivalent number of shares of our common stock on the payment date, based on the fair market value of our common stock on the date preceding the payment date. Non-management directors may also elect to defer all or a portion of their annual fee and
meeting fees, and such deferred amounts will accrue interest at a rate equal to the prime commercial lending rate announced from time to time by JPMorgan Chase (compounded quarterly), and shall be paid out at such time or times as directed by the
non-management director. See footnote (1) to the 2012 Director Compensation table for details regarding participation in these programs by our non-management directors.

The table below summarizes the total compensation paid to or earned by our non-management directors during 2012. The table does not
include the fees payable to the two members of our special committee, which will be payable in 2013. The amounts included in the Stock Awards and Option Awards columns reflect the aggregate grant date fair value, and do not
necessarily equate to the income that will ultimately be realized by the director for these awards.

|(1) | Non-management directors may elect to exchange all or a portion of their annual fee for an equivalent number of shares of our common stock. Each of Messrs. Flores and
Ford elected to receive an equivalent number of shares of our common stock in lieu of 100% of his annual fee. Mr. Carmichael elected to receive an equivalent number of shares of our common stock in lieu of 50% of his annual fee. The amounts
reflected include the fees used to purchase shares of our common stock.

|(2) | Amounts reflect the aggregate grant date fair value of the stock awards (restricted stock units or RSUs) and option awards (options). RSUs are valued on the date of
grant at the closing sale price per share of our common stock. The Black-Scholes option model was used to determine the grant date fair value of the options that we granted to the directors. For information relating to the assumptions made by us in
valuing the option awards made to our non-management directors in fiscal year 2012, refer to Note 12 of our financial statements in our annual report on Form 10-K for the year ended December 31, 2012. On June 1, 2012, each non-management
director was granted options to purchase an aggregate 10,000 shares of our common stock and 2,500 RSUs. The options that were granted had a grant date fair value of $5.48 per option using the Black-Scholes option model. The grant of 2,500 RSUs had a

| | Payments made under the matching gifts program are no longer reportable as a perquisite because effective January 1, 2012, the limit on the annual amount of our
matching gifts was increased to $40,000 for all directors, officers, employees, full time consultants and certain retirees; therefore, matching gifts are no longer reflected in the All Other Compensation column for 2012 for any of our
directors.

Item 13. Certain Relationships and Related Transactions, and Director
Independence.

Certain Transactions

FM Services Company

We are parties to a services agreement with FM
Services Company, a wholly-owned subsidiary of FCX, under which FM Services Company provides us with executive, technical, administrative, accounting, financial, tax and other services pursuant to a fixed fee arrangement. FM Services Company also
provides these services to FCX. In 2012, we incurred approximately $ 7.7 million of costs under the services agreement, and we expect our costs under the services agreement to approximate $ 7.7 million in 2013.

Overlapping Directors and Officers

Several of our directors and executive officers also serve as directors or officers of FCX. Messrs. Moffett, Adkerson, Rankin, Day, Ford and Graham, each of whom serves as a director of our company, also
serve as directors of FCX. Messrs. Moffett and Adkerson and Ms. Quirk, each of whom serves as an executive officer of our company, also serve as executive officers of FCX. In addition, Ms. Parmelee, an executive officer of our company,
also serves as an officer of FCX. As of April 15, 2013, the overlapping board members and executive officers beneficially owned 9,070,442 shares of our common stock or about 5.6% of our outstanding common stock. For information regarding the
compensation paid to or earned by Messrs. Moffett and Adkerson and Ms. Quirk for services rendered to FCX, see the Executive Compensation Tables section of FCXs amendment to its Annual Report on Form 10-K for the year ended
December 31, 2012 as filed with the SEC.

FCX and PXP 2010 Transactions

On December 30, 2010, we issued 500,000 shares of our 5.75% Convertible Perpetual Preferred Stock, Series 2 (convertible perpetual
preferred stock) to Freeport-McMoRan Preferred LLC (Freeport Preferred), a wholly-owned subsidiary of FCX. In connection with the completion of the issuance of the convertible perpetual preferred stock to FCX Preferred, we entered into a stockholder
agreement with FCX and FCX Preferred (the FCX Stockholder Agreement), pursuant to which, among other things, FCX has the right to nominate individuals to serve on our board of directors (FCX Designated Directors). For as long as FCX and its
affiliates beneficially own (1) not less than 75% of our outstanding common stock on a fully diluted basis, immediately after the closing of the purchase of the convertible perpetual preferred stock, FCX will have the right to designate two
members of our board of directors; and (2) between 25% and 75% of our outstanding shares of our common stock on a fully diluted basis, immediately after the closing of the purchase of the convertible perpetual preferred stock, FCX will have the
right to designate one member of our board of directors; provided, however, that FCXs designation rights will be suspended during such time as at least two members of our board of directors are also members of FCXs board of directors.
Because FCX has shared at least two directors with us at all times since the execution of the FCX Stockholder Agreement, FCX has not been entitled to exercise its director designation rights. FCX will have no designation rights while FCX and its
affiliates beneficially own less than 25% of the percentage of our outstanding shares of common stock on a fully diluted basis owned at closing.

In connection with the completion of the issuance of the convertible perpetual preferred stock to FCX Preferred, we also entered into a registration rights agreement with FCX Preferred (FCX Registration
Rights Agreement) pursuant to which we agreed to, within 60 days of closing, (1) prepare and file with the SEC a shelf registration statement with respect to the securities issued to FCX Preferred (FCX Registrable Securities) that would permit
the FCX Registrable Securities to be resold in registered transactions and (2) use our commercially reasonable efforts to maintain the effectiveness of the shelf registration statement while FCX and its affiliates hold FCX Registrable
Securities. We filed with the SEC a shelf registration statement for the FCX Registrable Securities on February 28, 2011. In addition, under certain circumstances, the FCX Registration Rights Agreement permits FCX to demand or participate in an
underwritten public offering by us.

On December 30, 2010, we also issued 51 million shares of our common stock to
PXP in connection with our acquisition of PXPs shallow water Gulf of Mexico shelf properties, interests, and assets (the Acquisition). Upon consummation of the Acquisition, we and PXP entered into a stockholder agreement effective
December 30, 2010 (the PXP Stockholder Agreement), pursuant to which, among other things, the size of our board of directors was increased from 9 to 11 members and PXP was granted the right to nominate two individuals to serve on our board of
directors. As long as PXP and its affiliates beneficially own at least 10% of the issued and outstanding shares of our common stock, PXP will have the right to nominate two individuals to serve on our board of directors. If PXP and its affiliates
beneficially own less than 10% but at least 5% of the issued and outstanding shares of our common stock, PXP will have the right to nominate one individual to serve on our board of directors. If PXP and its affiliates

beneficially own less than 5% of the issued and outstanding shares of our common stock, PXP will not have the right to nominate any individuals to serve on our board of directors. Pursuant to the
PXP Stockholder Agreement, Messrs. Flores and Wombwell were nominated and elected to serve on our board of directors at the 2012 annual meeting.

In connection with the completion of the Acquisition, we and PXP also entered into a registration rights agreement (PXP Registration Rights Agreement) pursuant to which we agreed to, within 60 days of
closing of the Acquisition, (1) prepare and file with the SEC a shelf registration statement with respect to the 51 million shares of common stock issued to PXP (PXP Registrable Securities) that would permit some or all of the PXP
Registrable Securities to be resold in registered transactions and (2) use our commercially reasonable efforts to maintain the effectiveness of the shelf registration statement while PXP and its affiliates hold PXP Registrable Securities. We
filed with the SEC a shelf registration statement for the PXP Registrable Securities on February 28, 2011. In addition, under certain circumstances, the PXP Registration Rights Agreement permits PXP to demand or participate in an underwritten
public offering conducted by us.

Pending 2013 Merger with FCX and Related Voting and Support Agreement

On December 5, 2012, we entered into an agreement and plan of merger (the Merger Agreement) with FCX and INAVN Corp., a wholly-owned
subsidiary of FCX (the Merger Sub), pursuant to which the Merger Sub will merge with and into MMR, with MMR surviving the merger as a wholly-owned subsidiary of FCX (the Merger).

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each outstanding share of our common
stock will be converted into the right to receive $14.75 in cash, without interest, and 1.15 units of Gulf Coast Ultra Deep Royalty Trust that will be entitled to a 5% gross overriding royalty interest in hydrocarbons produced from MMRs
shallow water, ultra deep Gulf of Mexico prospects.

Consummation of the Merger is subject to the approval of the Merger
Agreement by our stockholders, both by (1) a majority of the outstanding shares of our common stock and (2) a majority of the outstanding shares of our common stock, excluding shares owned by FCX and its subsidiaries, PXP and its
subsidiaries, and certain officers and/or directors of MMR and FCX, and the approval by a majority of the outstanding shares of our common stock of an amendment to our certificate of incorporation to exempt FCX from certain interested stockholder
provisions.

On December 5, 2012, we entered into a Voting and Support Agreement (the Support Agreement) with FCX and PXP
with respect to the Merger, which generally requires that PXP, in its capacity as a stockholder of MMR, vote all of its shares of our common stock in favor of the Merger and related amendments to our certificate of incorporation and against
alternative transactions and generally prohibits PXP from transferring its shares of our common stock prior to the consummation of the Merger.

Director Transactions

Our Corporate Governance Guidelines provide that any transaction that would require disclosure under Item 404(a) of Regulation S-K of
the rules and regulations of the SEC, with respect to a director or executive officer, must be reviewed and approved, or ratified, annually by our board of directors. Any such related party transactions will only be approved or ratified if the board
of directors determines that such transaction will not impair the involved persons service to, and exercise of judgment on behalf of, the company, or otherwise create a conflict of interest that would be detrimental to the company. The
director transaction described below has been reviewed and approved or ratified by our board of directors.

B.M. Rankin, Jr.
and FM Services Company are parties to an agreement under which Mr. Rankin renders business consulting services to us and FCX relating to finance, accounting, guidance and advice on public policy matters and business development. FM Services
Company provides Mr. Rankin compensation, medical coverage and reimbursement for taxes in connection with those medical benefits. In 2012, FM Services Company paid Mr. Rankin $490,000 ($100,009 of which was allocated to us) pursuant to
this agreement. During 2012, the cost to FM Services Company (none of which was allocated to us) for Mr. Rankins personal use of company facilities was $24,300, medical expenses was $23,327, and reimbursement for a portion of his office
rent and utilities and for executive administrative and support services was $37,114. In addition, during 2012 the aggregate incremental cost to FM Services Company (none of which was allocated to us) for Mr. Rankins personal use of a
fractionally owned company aircraft, which includes the hourly operating rate, fuel costs and excise taxes, was $430,996. The aggregate incremental cost does not include the lost tax deduction for expenses that exceeded the amounts reported as
income for Mr. Rankin, which for fiscal year 2012 was approximately $81,915. Accordingly, the total received by Mr. Rankin during 2012 pursuant to this agreement was $1,005,737 of which $100,009 was allocated to us.

Board and Committee Independence

On the basis of information solicited from each director, and upon the advice and recommendation of the nominating and corporate
governance committee, our board has affirmatively determined that each of Messrs. Bush, Carmichael, Day, Ford and Graham and Ms. Mestayer has no material relationship with the company and is independent within the meaning of our corporate
governance guidelines, which comply with the applicable NYSE listing standards and SEC rules. In making this determination, the nominating and corporate governance committee, with assistance from the companys legal counsel, evaluated responses
to a questionnaire completed annually by each director regarding relationships and possible conflicts of interest between each director, the company and management. In its review of director independence, the committee considered all commercial,
industrial, banking, consulting, legal, accounting, charitable, and familial relationships any director may have with the company or management. The nominating and corporate governance committee recommended to the board that the six directors named
above be considered independent, which the board approved.

Our board also has determined that each of the members of the
audit, corporate personnel, and nominating and corporate governance committees has no material relationship with the company and satisfies the independence criteria (including the enhanced criteria with respect to members of the audit committee and
corporate personnel committee) set forth in the applicable NYSE listing standards and SEC rules.

|All Other Fees        |  |      |        |  |      |   |        | 



|(1) | Does not include $111,400 for services rendered primarily relating to audit activities associated with certain of our registration statements and related amendments
filed with the SEC in connection with the pending merger with FCX.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | Relates to services rendered in connection with review of quarterly earnings press releases and management reports to our board of directors.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------





The audit committee has determined that the provision of the services described above is compatible with maintaining the independence of
our independent registered public accounting firm.

Pre-Approval Policies and Procedures

The audit committees policy is to pre-approve all audit services, audit-related services and other services permitted by law
provided by our independent registered public accounting firm. In accordance with that policy, the audit committee annually pre-approves a list of specific services and categories of services, including audit, audit-related and other services, for
the upcoming or current fiscal year, subject to specified cost levels. Any service that is not included in the approved list of services must be separately pre-approved by the audit committee. In addition, if fees for any service exceed the amount
that has been pre-approved, then payment of additional fees for such service must be specifically pre-approved by the audit committee; however, any proposed service that has an anticipated or additional cost of no more than $30,000 may be
pre-approved by the chairperson of the audit committee, provided that the total anticipated costs of all such projects pre-approved by the chairperson during any fiscal quarter does not exceed $60,000.

At each regularly-scheduled audit committee meeting, management updates the audit committee on the scope and anticipated cost of
(1) any service pre-approved by the chairperson since the last meeting of the committee and (2) the projected fees for each service or group of services being provided by our independent registered public accounting firm. Since the May
2003 effective date of the SEC rules stating that an auditor is not independent of an audit client if the services it provides to the client are not appropriately approved, each service provided by our independent registered public accounting firm
has been approved in advance by the audit committee. During 2012, none of those services required use of the de minimis exception to pre-approval contained in the SECs rules.
