 TERM LOAN AGREEMENT dated as of February 14, 2013 (this
“Agreement”), among FREEPORT-MCMORAN COPPER & GOLD INC., a Delaware corporation, the other Borrower, if any, party hereto, the Lenders party hereto, JPMORGAN CHASE BANK, N.A. (“JPMCB”), as Administrative
Agent, and BANK OF AMERICA, N.A., as Syndication Agent. 
 The Borrowers (such term and each other capitalized term used and not
otherwise defined herein having the meaning assigned to it in Article I) have requested the Lenders to extend credit in the form of term loans in an aggregate principal amount of up to $4,000,000,000. The proceeds of Borrowings hereunder will be
used (i) to finance all or a portion of the cash consideration payable by FCX and/or any Subsidiary in connection with the MMR Acquisition, (ii) to refinance the MMR Specified Debt, (iii) to finance all or a portion of the cash
consideration payable by FCX and/or any Subsidiary in connection with the PXP Acquisition, (iv) to refinance the PXP Specified Debt, (v) to pay fees, expenses and other costs in connection with the MMR Acquisition and the PXP Acquisition
and financings relating thereto and (vi) for general corporate purposes. 
 The Lenders are willing to extend such credit
to the Borrowers on the terms and subject to the conditions set forth herein. Accordingly, the parties hereto agree as follows: 

ARTICLE I 

Definitions 
 SECTION 1.01. Defined Terms. As used in this Agreement, the following terms have the meanings specified below: 
 “ABR”, when used in reference to any Loan or Borrowing, refers to whether such Loan, or the Loans comprising such Borrowing, are bearing interest at a rate determined by reference to the
Alternate Base Rate. 
 “Adjusted LIBO Rate” means, with respect to any Eurodollar Borrowing for any Interest
Period, an interest rate per annum (rounded upwards, if necessary, to the next 1/100 of 1%) equal to (a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate. 

“Administrative Agent” means JPMorgan Chase Bank, N.A., in its capacity as administrative agent for the Lenders
hereunder. 
 “Administrative Questionnaire” means an Administrative Questionnaire in a form supplied by the
Administrative Agent. 







 “Affiliate” means, with respect to a specified Person, another Person that
directly, or indirectly through one or more intermediaries, Controls or is Controlled by or is under common Control with the Person specified. 
 “Agents” means, collectively, the Administrative Agent and the Syndication Agent. 
 “Agreement” has the meaning assigned to such term in the preamble hereto. 
 “Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on
such day plus  1/2 of 1% and (c) the Adjusted LIBO Rate on such day (or if such day is not a Business Day, the immediately preceding Business Day) for a deposit in dollars with a maturity of one month plus 1%. For
purposes of clause (c) above, the Adjusted LIBO Rate on any day shall be based on the rate per annum appearing on the Reuters “LIBOR01” screen displaying interest rates for dollar deposits in the London interbank market (or on any
successor or substitute screen provided by Reuters, or any successor to or substitute for such service, providing rate quotations comparable to those currently provided on such screen, as determined by the Administrative Agent from time to time) at
approximately 11:00 a.m., London time, two Business Days prior to such day for deposits in dollars with a maturity of one month. Any change in the Alternate Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate or the
Adjusted LIBO Rate shall be effective from and including the effective date of such change in the Prime Rate, the Federal Funds Effective Rate or the Adjusted LIBO Rate, respectively. 

“Applicable Rate” means, for any day, the applicable rate per annum set forth below under the caption “ABR
Spread”, “Eurodollar Spread” or “Ticking Fee”, as the case may be, based upon the Credit Ratings by Moody’s and S&P applicable on such day:

 For purposes of the foregoing, (a) if either Moody’s or S&P shall not have in effect a Credit Rating (other
than by reason of the circumstances referred to in the last sentence of this definition), then FCX and the Lenders shall negotiate in good faith to agree upon another rating agency to be substituted by an amendment to this Agreement for the rating
agency which shall not have a Credit Rating in effect, and pending the effectiveness of such amendment, the Applicable Rate shall be determined by reference to the available Credit Rating; (b) if the Credit Ratings established or deemed to have
been established by Moody’s and S&P shall fall within different Levels, the Applicable Rate shall be based on the higher of the two Credit Ratings unless one of the two Credit Ratings is two or


  
 2 








 
more Levels lower than the other, in which case the Applicable Rate shall be determined by reference to the Level next below that of the higher of the two Credit Ratings; and (c) if the
Credit Rating established or deemed to have been established by Moody’s and S&P shall be changed (other than as a result of a change in the rating system of Moody’s or S&P), such change shall be effective as of the date on which it
is first announced by the applicable rating agency. Each change in the Applicable Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such
change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, FCX and the Lenders shall negotiate in good faith to amend the definition
of “Applicable Rate” to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Rate shall be determined by reference to the Credit
Rating most recently in effect prior to such change or cessation. 
 “Assignment and Assumption” means an
assignment and assumption entered into by a Lender and an assignee (with the consent of any party whose consent is required by Section 9.04), and accepted by the Administrative Agent, in the form of Exhibit A attached hereto or any

lease of FCX or any Subsidiary entered into as part of a Project Financing or a sale and leaseback transaction subject to Section 6.04, (a) if such lease is a Capital Lease Obligation, the capitalized amount thereof that would appear on a
balance sheet of such Person prepared as of such date in accordance with GAAP and (b) if such lease is not a Capital Lease Obligation, the capitalized amount of the remaining lease payments under such lease that would appear on a balance sheet
of such Person prepared as of such date in accordance with GAAP if such lease were accounted for as a Capital Lease Obligation. 

“Attributable Debt Payments” means, for FCX and the Subsidiaries for any period, all payments made during such period in
respect of Attributable Debt. 
 “Available Domestic Cash” means, as of any date, the aggregate amount of cash

funds transferred to it available to the Borrowers by promptly crediting the amounts so received, in like funds, to an account of a Borrower maintained with the Administrative Agent in New York City and designated by the Borrowers in the applicable
Borrowing Request. 
 (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of

paragraph (a) of this Section and may, in reliance upon such assumption and in its sole discretion, make available to the Borrowers a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing
available to the Administrative Agent, then the applicable Lender and the Borrowers severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such

Borrowers may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising
each such portion shall be considered a separate Borrowing. 
 (b) To make an election pursuant to this Section, the Borrowers
shall notify the Administrative Agent of such election by telephone by the time that a

shall be continued as a Eurodollar Borrowing with an Interest Period of one month’s duration. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of
the Required Lenders, so notifies the Borrowers, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing

(iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof. 
 (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations
recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of either Borrower to repay the Loans in accordance with the
terms of this Agreement. 
 (e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event,
the Borrowers shall prepare, execute and deliver to such Lender a promissory note payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the
Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the payee named therein (or to such
payee and its registered assigns); provided that the failure of any Lender to maintain such promissory notes or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of
this Agreement. 
 SECTION 2.08. Amortization. (a) The Borrowers shall repay Borrowings on the last Business Day of
each March, June, September and December, beginning with the first such day on or after the first anniversary of the Initial Closing Date and ending with the last such day prior to the fourth anniversary of the Initial Closing Date, in an aggregate
principal amount for each such date equal to (i) in the case of any such date on or after the first anniversary of the Initial Closing Date and prior to the second anniversary of the Initial Closing Date, 2.5% of the aggregate principal amount
of all Loans made on all Closing Dates (as such amount may be adjusted pursuant to paragraph (b) of this Section), (ii) in the case of any such date on or after the second anniversary of the Initial Closing Date and prior to the third
anniversary of the Initial Closing Date, 3.75% of the aggregate principal amount of all Loans made on all Closing Dates (as such amount may be adjusted pursuant to paragraph (b) of this Section) and (iii) in the case of any such date on or
after the third anniversary of the Initial Closing Date and prior to the fourth anniversary of the Initial Closing Date, 5.0% of the aggregate principal amount of all Loans made on all Closing Dates (as such amount may be adjusted pursuant to
paragraph (b) of this Section). To the extent not previously paid, all Loans shall be due and payable on the Maturity Date. 
 (b) Any prepayment of a Borrowing shall be applied to reduce the subsequent scheduled repayments of the Borrowings to be made pursuant to this Section as directed by the Borrowers, and if no such
direction is provided, in direct order 

  
 41 









 
against the remaining scheduled installments of principal due in respect of the Loans under this Section. 
 (c) Prior to any repayment of any Borrowings under this Section, the Borrowers shall select the Borrowing or Borrowings to be repaid and shall notify the Administrative Agent by telephone (confirmed by
hand delivery or facsimile) of such selection not later than 12:00 noon, New York City time, three Business Days before the scheduled date of such repayment; provided that if the Borrower does not notify the Administrative Agent, such
repayment shall be applied to any outstanding Borrowings as determined by the Administrative Agent. Each repayment of a Borrowing shall be applied ratably to the Loans included in the repaid Borrowing. Repayments of Borrowings shall be accompanied
by accrued interest on the amounts repaid. 
 SECTION 2.09. Prepayment of Loans. (a) The Borrowers shall have the
right at any time and from time to time to prepay any Borrowing in whole or in part, without premium or penalty, subject to the requirements of this Section and to the making of any payment required under Section 2.14. 

(b) Prior to any optional prepayment of Borrowings hereunder, the Borrowers shall select the Borrowing or Borrowings to be prepaid and
shall specify such selection in the notice of such prepayment pursuant to paragraph (c) of this Section. 
 (c) The
Borrowers shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three Business Days before
the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the
principal amount of each Borrowing or portion thereof to be prepaid. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02.
Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.11. 

SECTION 2.10. Fees. (a) The Borrowers agree to pay to the Administrative Agent for the account of each Lender a ticking fee,
which shall accrue at the Applicable Rate on the daily average unused amount of the Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which the Commitments terminate. Accrued ticking fees
shall be payable in arrears on each third mensiversary of the Effective Date, on each Closing Date, and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof. All commitment fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 

  
 42 









 (b) The Borrowers agree to pay to the Administrative Agent, for its own account, fees
payable in the amounts and at the times separately agreed upon between the Borrowers and the Administrative Agent. 
 (c) All
fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, in the case of ticking fees and upfront fees, to the Lenders. Fees paid shall not be refundable under any
circumstances. 
 SECTION 2.11. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at
the Alternate Base Rate plus the Applicable Rate. 
 (b) The Loans comprising each Eurodollar Borrowing shall bear interest at
the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate. 
 (c) Notwithstanding the
foregoing, if any principal of or interest on any Loan or any fee or other amount payable by either Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall, on and after the date
the Required Lenders so request, bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding
paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section. 
 (d) Accrued interest on each Loan shall be payable by the Borrowers in arrears on each Interest Payment Date for each such Loan; provided that (i) interest accrued pursuant to
paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the Maturity Date), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the
effective date of such conversion. 
 (e) All interest hereunder shall be computed on the basis of a year of 360 days, except
that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for
the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or Adjusted LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent
manifest error. 
 SECTION 2.12. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a
Eurodollar Borrowing: 

  
 43 









 (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or 
 (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or
maintaining their Loans included in such Borrowing for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the
Borrowers and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrowers and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any
Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall
be made as an ABR Borrowing. 
 SECTION 2.13. Increased Costs. (a) If any Change in Law shall: 

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with
or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); 
 (ii) impose on any Lender or the London interbank market any other condition (other than Taxes) affecting this Agreement or Eurodollar Loans made by such Lender; or 

(iii) subject any Lender to any Taxes (other than (A) Indemnified Taxes, (B) Excluded Taxes and (C) Other
Connection Taxes that are income or franchise Taxes imposed on (or measured by) the net income of such Lender or that are branch profits Taxes) on its Loans, loan principal, Commitment, or other obligations, or its deposits, reserves, other
liabilities or capital attributable thereto; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), in each case by or in an
amount which such Lender in its sole judgment deems material in the context of this Agreement and its Loans and Commitments hereunder, then the Borrowers will pay to such Lender such additional amount or amounts as will compensate such Lender for
such additional costs incurred or reduction suffered. 
 (b) If any Lender determines that any Change in Law regarding capital
or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender,
to a level below that which such Lender or such Lender’s holding company could have achieved but for such 

  
 44 









 
Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy or liquidity), by an amount which such
Lender in its sole judgment deems to be material in the context of this Agreement and its Loans and Commitments hereunder, then from time to time the Borrowers will pay to such Lender such additional amount or amounts as will compensate such Lender
or such Lender’s holding company for any such reduction suffered. 
 (c) A certificate of a Lender setting forth the amount
or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. The
Borrowers shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such
Lender’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that
such Lender notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to
such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. 
 SECTION 2.14. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as
a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure by the Borrowers to borrow, convert, continue or prepay any Eurodollar Loan
on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked or extended under Section 2.03 and is revoked or extended in accordance therewith), or (d) the assignment of any Eurodollar
Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrowers pursuant to Section 2.17, then, in any such event, the Borrowers shall compensate each Lender for the loss, cost and expense
attributable to such event. Such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such
Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to
borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid
were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. The Borrowers 

  
 45 









 
shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 SECTION 2.15. Taxes. (a) Any and all payments by or on account of any obligation of either Borrower or any other Loan Party hereunder or under any other Loan Document shall be made free and
clear of and without deduction for any Taxes, except as required by applicable law (as determined in the good faith discretion of the applicable withholding agent); provided that if any withholding agent shall be so required to deduct any
Indemnified Taxes from such payments, then (i) the sum payable by the applicable Loan Party shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this
Section 2.15) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such withholding agent shall make such deductions and (iii) such
withholding agent shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 

(b) Each Borrower and any other Loan Party shall timely pay to the relevant Governmental Authority in accordance with applicable law, or
at the option of the Administrative Agent timely reimburse it for, Other Taxes. 
 (c) The Loan Parties shall jointly and
severally indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes paid by the Administrative Agent or such Lender, as the case may be, or that are required to be
withheld or deducted from a payment thereto by or on account of any obligation of a Loan Party hereunder or under any other Loan Document (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section), and
any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority, provided, however, that the Loan Parties
shall not be obligated to make payment to the Administrative Agent or any Lender pursuant to this Section in respect of penalties, interest and other liabilities attributable to any Indemnified Taxes if such penalties, interest or other liabilities
are attributable to the gross negligence or wilful misconduct of the Administrative Agent or such Lender. A certificate as to the amount of such payment or liability, including a calculation thereof determined in the sole discretion of the Lender or
the Administrative Agent, delivered to a Loan Party by a Lender (with a copy to the Administrative Agent) or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. 

(d) As soon as practicable after any payment of Indemnified Taxes by a Loan Party to a Governmental Authority, such Loan Party shall
deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to
the Administrative Agent. 

  
 46 









 (e) Each Lender shall severally indemnify the Administrative Agent for any Taxes (but, in
the case of any Indemnified Taxes, only to the extent that any Loan Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so) attributable to such Lender
that are paid or payable by the Administrative Agent in connection with any Loan Document and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. The indemnity under this Section 2.15(e) shall be paid within 10 days after the Administrative Agent delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the
Administrative Agent. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under
any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e). 

(f) (i) Any Lender that is entitled to an exemption from, or reduction of, any applicable withholding Tax with respect to any
payments under any Loan Document shall deliver to the Borrowers and the Administrative Agent, at the time or times reasonably requested by the Borrowers or the Administrative Agent, such properly completed and executed documentation reasonably
requested by the Borrowers or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by the Borrowers or the Administrative Agent, shall deliver such
other documentation prescribed by law or reasonably requested by the Borrowers or the Administrative Agent as will enable the Borrowers or the Administrative Agent to determine whether or not such Lender is subject to any withholding (including
backup withholding) or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in
Section 2.15(f)(ii)(A) through (E) below) shall not be required if in the Lender’s judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice
the legal or commercial position of such Lender. Upon the reasonable request of the Borrowers or the Administrative Agent, any Lender shall update any form or certification previously delivered pursuant to this Section 2.15(f). If any form or
certification previously delivered by such Lender pursuant to this Section 2.15(f) expires or becomes obsolete or inaccurate in any respect, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or
inaccuracy) notify the Borrowers and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so. 

(ii) Without limiting the generality of the foregoing, any Lender shall, if it is legally eligible to do so, deliver to
the Borrowers and the Administrative Agent (in such number of copies as is reasonably requested by the Borrowers and the Administrative Agent, on or prior to the date on which such Lender becomes a party hereto) duly completed and executed copies of
whichever of the following is applicable: 

  
 47 









 (A) in the case of a Lender that is a U.S. Person, executed originals of IRS
Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding Tax; 
 (B) in the case of a
Non-U.S. Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or
reduction of, U.S. Federal withholding Tax pursuant to the “interest” article of such tax treaty and (2) with respect to any other applicable payments under this Agreement, executed originals of IRS Form W-8BEN establishing an
exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; 

(C) in the case of a Non-U.S. Lender for which payments under this Agreement constitute income that is effectively
connected with such Lender’s conduct of a trade or business in the United States, executed originals of IRS Form W-8ECI; 
 (D) in the case of a Non-U.S. Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code both (1) executed originals of IRS Form W-8BEN and (2) a
certificate substantially in the form of Exhibit F (a “U.S. Tax Certificate”) to the effect that such Lender is not (a) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (b) a
“10 percent shareholder” of either Borrower within the meaning of Section 881(c)(3)(B) of the Code, (c) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code or (d) conducting a
trade or business in the United States with which the relevant interest payments are effectively connected; 

(E) in the case of a Non-U.S. Lender that is not the beneficial owner of payments made under this Agreement (including a
partnership or a participating Lender), (1) executed originals of IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D) and (F) of this paragraph (f)(ii) that would be required of
each such beneficial owner or partner of such partnership if such beneficial owner or partner were a Lender; provided, however, that if the Lender is a partnership and one or more of its partners are claiming the exemption for
portfolio interest under Section 881(c) of the Code, such Lender may provide a U.S. Tax Certificate on behalf of each such partner; or 
 (F) any other form prescribed by applicable law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary documentation as is necessary to
enable the Borrowers or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld. 

  
 48 









 (iii) If a payment made to a Lender under any Loan Document would be subject
to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall
deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by
Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has or
has not complied with such Lender’s obligations under FATCA and, as necessary, to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.15(f)(iii), “FATCA” shall include any
amendments made to FATCA after the date of this Agreement. 
 (g) If any party determines, in its sole discretion exercised in
good faith, that it has received a refund and/or credit of any Taxes as to which it has been indemnified pursuant to this Section 2.15 (including additional amounts paid pursuant to this Section 2.15), it shall pay to the indemnifying
party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.15 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including any Taxes) of such indemnified
party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid
to such indemnifying party pursuant to the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental
Authority. Notwithstanding anything to the contrary in this paragraph (g), in no event will the indemnified party be required to pay an amount to an indemnifying party pursuant to this paragraph (g) the payment of which would place the
indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the
indemnification payments or additional amounts with respect to such Tax had never been paid. 
 (h) Nothing contained in this
Section 2.15 shall require the Administrative Agent or any Lender (or permitted assignee or Participant) to make available any of its Tax returns or any other information that it deems to be confidential or proprietary, to any Loan Party or any
other Person. 
 (i) Each party’s obligations under this Section 2.15 shall survive any resignation or replacement of
the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all other obligations under any Loan Document. 

(j) For purposes of this Section 2.15, the term “applicable law” includes FATCA. 

  
 49 









 SECTION 2.16. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.
(a) Each Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest or fees, or of amounts payable under Section 2.13, 2.14, 2.15 or otherwise) prior to the time
expressly required hereunder or under such other Loan Document for such payment (or, if no such time is expressly required, prior to 12:00 noon, New York City time), on the date when due, in immediately available funds, without set-off or
counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except that payments pursuant to Sections 2.13, 2.14, 2.15 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to
other Loan Documents shall be made to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If
any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable
for the period of such extension. All payments under each Loan Document shall be made in dollars. 
 (b) If at any time
insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due
hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of principal then due to such parties. 
 (c) If any Lender shall, by exercising any right of
set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon
than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the
payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any
payment made by either Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or
participant, other than to such Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable
law, that any Lender acquiring a 

  
 50 









 
participation pursuant to the foregoing arrangements may exercise against either Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of such Borrower in the amount of such participation. 
 (d) Unless the Administrative Agent shall have received
notice from the Borrowers prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrowers will not make such payment, the Administrative Agent may assume that the Borrowers have
made such payment on such date in accordance herewith and may, in reliance upon such assumption and in its sole discretion, distribute to the Lenders the amount due. In such event, if the Borrowers have not in fact made such payment, then each of
the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon for each day from and including the date such amount is distributed to it to but excluding the date
of payment to the Administrative Agent at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04, 2.16(d) or 9.03(c), or fail to
purchase participations in the Loans of the other Lenders required to be purchased by it pursuant to Section 2.16(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 

SECTION 2.17. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under
Section 2.13, or if either Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to
designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment
(i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to
such Lender. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b) If any Lender requests compensation under Section 2.13, or if either Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 2.15, or if any Lender has failed to consent to a proposed amendment, waiver, discharge or termination which pursuant to the terms of Section 9.02 requires the consent of all of the Lenders affected and with respect to
which the Required Lenders shall have granted their consent, then FCX may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in


  
 51 









 
accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to one or more assignees that shall assume such

withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such

the Loan Documents to which it is to be party, the Borrowings hereunder and the Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except (i) such as

financial statements present fairly, in all material respects, the consolidated financial position and consolidated results of operations and cash flows of FCX and its consolidated Subsidiaries as of such dates and for such periods in accordance
with GAAP, subject to normal year-end adjustments and the absence of footnotes in the case of such unaudited financial statements. 
 (b) Except as set forth in Schedule 3.04(b), since December 31, 2011, there has been no material adverse change in (i) the business, operations or financial condition of FCX and its

 SECTION 3.05. Properties. (a) Except to the extent that any failure to do so
individually or in the aggregate would not reasonably be expected to result in a Material Adverse Effect and except for approvals from any Governmental Authority customarily obtained after the closing of sales or transfer involving assets in the

result in a Material Adverse Effect, FCX and each of its Subsidiaries owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by FCX and its
Subsidiaries does not infringe upon the rights of any other Person. 
 SECTION 3.06. Litigation and Environmental
Matters. (a) Except for the Disclosed Matters, there are no actions, suits or proceedings by or before any Governmental Authority pending against or, to the knowledge of either Borrower, threatened against or affecting FCX or any of its
Subsidiaries that would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. 
 (b)
Except for the Disclosed Matters and except for any other matters that, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect, neither FCX nor any of its Subsidiaries (i) has failed to comply

to them or their properties and all indentures, agreements (including, so long as PTFI is a Subsidiary, the Contract of Work) and other instruments binding upon them or their properties, except where the failure to do so, individually or in the
aggregate, would not reasonably be expected to result in a Material Adverse Effect. 
 SECTION 3.08. Investment Company
Status. No Loan Party is an “investment company” under the Investment Company Act of 1940. 
 SECTION 3.09.
Taxes. FCX and its Subsidiaries have timely filed or caused to be filed all Tax returns and reports required to have been filed by them and have paid or caused to be paid all Taxes required to have been paid by them, except (i) any Taxes
that are being contested in good faith by appropriate proceedings and for which FCX or such Subsidiary, as applicable, has, to the extent required by GAAP, set aside on its books adequate reserves and (ii) returns and reports the non-filing of
which, 

  
 54 









 
and Taxes the non-payment of which, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. 

SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such
ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. Except as would not reasonably be expected to result in a Material Adverse Effect, the present value of all
accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed
the fair market value of the assets of all such Plans, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Financial Accounting Standards Codification Topic 715) did
not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans. 
 SECTION 3.11. Disclosure. The Confidential Information Materials and the other reports, financial statements, certificates and other information furnished in writing by the Borrowers or any of
their representatives in connection with the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished), are complete and correct in all material respects and do not contain any untrue
statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not materially misleading in light of the circumstances under which such statements have been made. Notwithstanding the
foregoing, it is understood and agreed that the periodic reports and other information of FCX filed with the SEC pursuant to Section 13 of the Exchange Act speak as of the date of such reports or other filings and not of any subsequent time
and, therefore, the representation set forth in the first sentence of this paragraph is applicable to the information contained in such reports or other filings only as of the date of such reports or other filings. Additionally, notwithstanding
anything to the contrary contained herein, the representation in the first sentence of this paragraph shall not apply to forward-looking information contained in the filings made by FCX or PXP with the SEC pursuant to Section 13 of the Exchange
Act, and the Borrowers shall have no liability with respect to such forward-looking information, except to the extent that FCX would have liability to investors in its public securities under the Exchange Act after the application of
Section 21E of the Exchange Act. 
 SECTION 3.12. Insurance. Schedule 3.12 sets forth a description of all material
insurance maintained by or on behalf of FCX and its Subsidiaries as of the Effective Date. As of the Effective Date, all material premiums in respect of such insurance are current and such insurance is in full force and effect. FCX believes that the
insurance maintained by or on behalf of FCX and its Subsidiaries is adequate. 
 SECTION 3.13. Labor Matters. As of the
Effective Date, there are no strikes, lockouts or slowdowns against FCX or any Subsidiary pending or, to the knowledge of FCX, threatened, that would reasonably be expected to result, individually


  
 55 









 
or in the aggregate, in a Material Adverse Effect. The consummation of the Transactions will not give rise to any right of termination or right of renegotiation on the part of any union under any
collective bargaining agreement to which FCX or any Subsidiary is a party that would reasonably be expected to result, individually or in the aggregate, in a Material Adverse Effect. 

SECTION 3.14. Federal Reserve Regulations. No part of the proceeds of the Loans will be used, whether directly or indirectly, for
any purpose which entails a violation (including on the part of any Lender) of Regulation U or X of the Board. 
 SECTION
3.15. Pari Passu Status. The Obligations of the Borrowers under this Agreement rank, and will rank, at least pari passu in right of payment with all unsecured, unsubordinated Indebtedness of the Borrowers. 

SECTION 3.16. OFAC. Neither FCX nor any of its Subsidiaries, nor any (a) director or officer thereof or (b) to the
knowledge of either Borrower, any agent, employee or Affiliate thereof, is currently subject to any U.S. sanctions administered or enforced by OFAC, and the Borrowers will not directly or indirectly use the proceeds from the Loans or lend,
contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other Person, for the purpose of financing activities of or with any Person or any country or territory that, at the time of such financing, is the
subject of any OFAC sanctions. 
 SECTION 3.17. FCPA. No part of the proceeds of the Loans will be used, directly or
indirectly, for any payments to any officer or employee of a government, or government-controlled entity, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to
obtain, retain or direct business or obtain any improper advantage, in violation of the FCPA. 
 SECTION 3.18. Solvency.
Immediately after the consummation of the Transactions and the other transactions to occur on the applicable Closing Date, as of such Closing Date (a) the fair value of the assets of the Borrowers and the Subsidiaries, taken as a whole, will
exceed their debts and liabilities, subordinated, contingent or otherwise, (b) the present fair saleable value of the assets of the Borrowers and the Subsidiaries, taken as a whole, will be greater than the amount that will be required to pay
the probable liability on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured, (c) the Borrowers and the Subsidiaries, taken as a whole, will be able to pay
their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured and (d) the Borrowers and the Subsidiaries, taken as a whole, will not have unreasonably small capital with which to
conduct the business in which they are engaged, as such business is conducted at the time of and is proposed to be conducted following the applicable Closing Date.

necessary for its operations and properties, and (iii) conduct any remedial or reclamation actions in compliance with applicable Environmental Laws; provided, however, that the Borrowers and the Subsidiaries shall not be required

reserves, in accordance with GAAP, are maintained in connection therewith. If either Borrower is in default of its obligations under this paragraph, the Borrowers will, at the request of the Required Lenders through the Administrative Agent, provide

shall deliver a copy of any subsequent voluntary External Environmental Report to the Administrative Agent within 30 days of delivery of the final such report to FCX. The voluntary External Environmental Reports shall be delivered to the
Administrative Agent by FCX at three year intervals (though for the avoidance of doubt, delivery will in no event be required to be made on a specific date following such interval) unless the applicable Governmental Authority in Indonesia makes
preparation of such a report mandatory, in which case, FCX shall provide such External Environmental Reports to the Administrative Agent at intervals as required by Indonesian law. The Borrowers will implement, as promptly as practicable after the
receipt of any External Environmental Report, any recommendations contained in such report if the failure to implement such recommendations could reasonably be expected to result in a Material Adverse Effect.

it intends to use for substantially the same purpose or purposes as the property sold or transferred, except for (a) any such sale and leaseback of any fixed or capital assets that is made for cash consideration in an amount not less than the
cost of such fixed or capital asset and is consummated within 180 days after FCX or any Subsidiary acquires or completes the construction of such fixed or capital asset; (b) any such sale and leaseback of Project Financing Assets as part of a
Project Financing, provided in each case that such sale and leaseback is solely for cash; and (c) any sale and leaseback of fixed or capital assets; provided that the aggregate amount of the Attributable Debt in respect of such

times: (x) declare the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of

It is understood and agreed that (x) the Administrative Agent and the Lenders shall not be permitted to take any of the foregoing actions with
respect to any Default or Event of Default occurring during the period between the Effective Date and the Initial Closing Date, until after the Initial Closing Date, and the funding of the Loans by the Lenders on the Initial Closing Date, shall have
occurred and (y) except pursuant to clause (ii) of the preceding paragraph or as provided in Section 2.06, the Administrative Agent and the Lenders shall not have any right to terminate any unused Commitments upon the occurrence of
any Default or Event of Default. 
 ARTICLE VIII 
 The Agents 
 Each of the Lenders hereby irrevocably appoints the entity
named as Administrative Agent in the heading of this Agreement and its successors to serve as administrative agent under the Loan Documents, and authorizes the Administrative Agent to take such actions and to exercise such powers as are delegated to
the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto. 
 Each of the Agents hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such Person and its
Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with either Borrower or any Subsidiary or other Affiliate thereof as if such Person
were not an Agent hereunder and without any duty to account therefor to the Lenders. 
 The Administrative Agent shall not have
any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of
whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or to exercise any discretionary power, except discretionary rights and powers expressly contemplated by the
Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall


  
 79 









 
believe in good faith to be necessary, under the circumstances as provided in the Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in
its opinion, could expose the Administrative Agent to liability or be contrary to any Loan Document or applicable law, and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose,
and shall not be liable for the failure to disclose, any information relating to the Borrowers, any Subsidiary or any Affiliate of any of the foregoing that is communicated to or obtained by the Person serving as Administrative Agent or any of its
Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or
as the Administrative Agent shall believe in good faith to be necessary, under the circumstances as provided in the Loan Documents) or in the absence of its own gross negligence or wilful misconduct, as determined by a court of competent
jurisdiction by a final and non-appealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by FCX or a Lender, and the
Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or
other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document or the occurrence of any Default, (iv) the
sufficiency, validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document,
other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or satisfaction of any condition that expressly refers to the matters described therein being acceptable or satisfactory to the Administrative
Agent. 
 The Administrative Agent shall be entitled to rely, and shall not incur any liability for relying, upon any notice,
request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise
authenticated by the proper Person (whether or not such Person in fact meets the requirements set forth in the Loan Documents for being the signatory, sender or authenticator thereof). The Administrative Agent also shall be entitled to rely, and
shall not incur any liability for relying, upon any statement made to it orally or by telephone and believed by it to be made by the proper Person (whether or not such Person in fact meets the requirements set forth in the Loan Documents for being
the signatory, sender or authenticator thereof), and may act upon any such statement prior to receipt of written confirmation thereof. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), independent
accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 

The Administrative Agent may perform any of and all its duties and exercise its rights and powers hereunder or under any other Loan
Document by or 

  
 80 









 
through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any of and all their duties and exercise their rights and
powers through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 
 Subject to the terms of this paragraph, the Administrative Agent may resign at any time from its capacity as such. In connection with such resignation, the Administrative Agent shall give notice of its
intent to resign to the Lenders and the Borrowers. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrowers, to appoint a successor. If no successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its intent to resign, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents. The fees payable
by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed by the Borrowers and such successor. Notwithstanding the foregoing, in the event no successor Administrative Agent
shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its intent to resign, the retiring Administrative Agent may give notice of the effectiveness of its
resignation to the Lenders and the Borrowers, whereupon, on the date of effectiveness of such resignation stated in such notice, (a) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the
other Loan Documents, and (b) the Required Lenders shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, provided that (i) all payments required to be made
hereunder or under any other Loan Document to the Administrative Agent for the account of any Person other than the Administrative Agent shall be made directly to such Person and (ii) all notices and other communications required or
contemplated to be given or made to the Administrative Agent shall also directly be given or made to each Lender. Following the effectiveness of the Administrative Agent’s resignation from its capacity as such, the provisions of this Article
and Section 9.03, as well as any exculpatory, reimbursement and indemnification provisions set forth in any other Loan Document, shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective
Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent and in respect of the matters referred to in the proviso under clause (a) above. 

Each Lender acknowledges that it has, independently and without reliance upon either Agent, any person listed on the cover page of this
Agreement as an arranger, 

  
 81 









 
or any other Lender, or any of the Related Parties of any of the foregoing, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to
enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon either Agent, any person listed on the cover page of this Agreement as an arranger, or any other Lender, or any of the Related Parties of
any of the foregoing, and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any
related agreement or any document furnished hereunder or thereunder. 
 Each Lender, by delivering its signature page to this
Agreement on or prior to the Effective Date and funding its Loans on the applicable Closing Date, or delivering its signature page to an Assignment and Assumption pursuant to which it shall become a Lender hereunder, shall be deemed to have
acknowledged receipt of, and consented to and approved, each Loan Document and each other document required to be delivered to, or be approved by or satisfactory to, the Administrative Agent or the Lenders on the Effective Date and a Closing Date,
as applicable. 
 No Credit Party shall have any right individually to enforce any Guarantee of the Obligations, it being
understood and agreed that all powers, rights and remedies under the Loan Documents may be exercised solely by the Administrative Agent on behalf of the Credit Parties in accordance with the terms thereof. Each Credit Party, whether or not a party
hereto, will be deemed, by its acceptance of the benefits of the Guarantees of the Obligations provided under the Loan Documents, to have agreed to the foregoing provisions. 
 Notwithstanding anything herein to the contrary, neither the Syndication Agent nor any Person named on the cover page of this Agreement as an arranger or a documentation agent shall have any duties or
obligations under this Agreement or any other Loan Document (except in its capacity, as applicable, as a Lender), but all such Persons shall have the benefit of the indemnities provided for hereunder. 

The provisions of this Article are solely for the benefit of the Agents and the Lenders, and neither Borrower nor any other Loan Party
shall have any rights as a third party beneficiary of any such provisions. 
 ARTICLE IX

 SECTION 9.01. Notices. (a) Except in the case of notices and other communications expressly permitted to be given by telephone (and subject to paragraph (b) below), all notices and other
communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopy, as follows: 

  
 82 









 (i) if to either Borrower, to it at Freeport-McMoRan Copper & Gold
Inc., 333 N. Central Avenue, Phoenix, AZ 85004, Attention of Treasurer (Telecopy No. (602) 366-7321);

Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communication pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular
notices or communications. 
 (c) Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt. 

SECTION 9.02. Waivers; Amendments. (a) No failure or delay by any Agent or any Lender in exercising any right or power
hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights and remedies of the Agents and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would
otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether any Agent
or any Lender may have had notice or knowledge of such Default at the time. 
 (b) Neither this Agreement nor any other Loan
Document nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by each of the Borrowers and the Required Lenders or, in the case
of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Administrative 

  
 83 









 
Agent and the Loan Party or Loan Parties that are parties thereto, in each case with the consent of the Required Lenders; provided that no such agreement shall (i) increase the
Commitment of any Lender without the written consent of such Lender, (ii) reduce or forgive the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of the Lender
holding such Loan or for whose account such principal, interest or fee is payable, (iii) postpone the maturity of any Loan, or any date for the payment of any interest or fees payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of the Lender holding such Loan or Commitment or for whose account such interest or fee is payable, (iv) change Section 2.16(b) or
(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section or the percentage set forth in the definition of
“Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the
written consent of each Lender, or (vi) except as expressly provided for in the Loan Documents, release all or substantially all the Subsidiary Guarantors from their Guarantees, if any, under the Loan Documents or limit the liability of all or
substantially all the Subsidiary Guarantors in respect of such Guarantees, without the written consent of each Lender, provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of any Agent without
the prior written consent of such Agent. 
 SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) Each Borrower
agrees to pay (i) all reasonable out-of-pocket expenses incurred by each Agent and its Affiliates, including the reasonable and documented fees, charges and disbursements of counsel for each Agent, in connection with the syndication of the
credit facilities provided for herein, the preparation and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be
consummated) and (ii) all reasonable out-of-pocket expenses incurred by any Agent or any Lender, including the fees, charges and disbursements of any counsel for any Agent or any Lender, in connection with the enforcement or protection of its
rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made hereunder, including all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in
respect of such Loans. 
 (b) Each Borrower agrees to indemnify each Agent, each Lender and each Related Party of any of the
foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and
disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument
contemplated hereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds
thereof, (iii) any actual or 

  
 84 









 
alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or operated by either Borrower or any of its Subsidiaries, or any Environmental Liability
related in any way to either Borrower or any of its Subsidiaries, other than losses, claims, damages, liabilities and related costs and expenses arising from a release of Hazardous Materials or Environmental Liability (except releases of Hazardous
Materials or Environmental Liabilities actually caused by either Borrower or any of its Subsidiaries or any of their respective tenants, contractors or agents) to the extent (and only to the extent) first occurring and first existing after title to
the relevant real property or facility is vested in any Agent or Lender or other party after the completion of foreclosure proceedings or the granting of a deed-in-lieu of foreclosure or similar transfer of title, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence, bad faith or willful misconduct of such Indemnitee. This Section 9.03(b) shall not apply with respect to Taxes other than any Taxes that represent losses or damages arising from any non-Tax claim. 

(c) To the extent that either Borrower fails to pay any amount required to be paid by it to any Agent under paragraph (a) or
(b) of this Section (but without affecting such Borrower’s obligations thereunder), each Lender severally agrees to pay to the applicable Agent such Lender’s pro rata share (determined as of the time that the applicable unreimbursed
expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent in its
capacity as such. For purposes of the immediately preceding sentence, a Lender’s “pro rata share” shall be determined based upon its share of the unused Commitments and outstanding Loans at the time. The obligations of the Lenders
under this paragraph (c) are subject to the last sentence of Section 2.02(a) (which shall apply mutatis mutandis to the Lenders’ obligations under this paragraph (c)). If any action, suit or proceeding arising from any
of the foregoing is brought against any Lender, any Agent or other Person indemnified or intended to be indemnified pursuant to this Section 9.03, FCX, to the extent and in the manner directed by such indemnified party, will resist and defend
such action, suit or proceeding or cause the same to be resisted and defended by counsel designated by FCX (which counsel shall be satisfactory to such Lender, such Agent or other Person indemnified or intended to be indemnified). If FCX shall fail
to do any act or thing which it has covenanted to do hereunder or any representation or warranty on the part of FCX contained in this Agreement shall be breached, any Lender or any Agent may (but shall not be obligated to) do the same or cause it to
be done or remedy any such breach, and may expend its funds for such purpose. Any and all amounts so expended by any Lender or any Agent shall be repayable to it by FCX immediately upon such Person’s demand therefor. 

(d) To the extent permitted by applicable law, neither Borrower shall assert, and each hereby waives, any claim against any Indemnitee on
any theory of 

  
 85 









 
liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement
or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof. 
 (e) All amounts due under
this Section shall be payable not later than 10 days after written demand therefor. 
 SECTION 9.04. Successors and
Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) a Borrower may not assign or otherwise
transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by a Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise
transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby, Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Agents and the Lenders) any legal or equitable right, remedy
or claim under or by reason of this Agreement. 
 (b) (i) No Lender may assign all or any portion of its Commitment
hereunder prior to the earlier of (A) the Combined Closing Date and (B) the occurrence of both of the MMR Termination Date and the PXP Termination Date (such earlier date, the “Final Closing Date”). Subject to the
conditions set forth in paragraph (b)(ii) below, any Lender may, after the Final Closing Date has occurred, assign to one or more assignees (other than any natural person) all or a portion of its rights and obligations under this Agreement
(including all or a portion of the Loans at the time owing to it) with the prior consent (such consent not to be unreasonably withheld or delayed) of the Administrative Agent, and, if the proposed assignee is a competitor, or an Affiliate of a
competitor, of the Borrower or any of its Affiliates, the Borrowers. 
 (ii) Assignments shall be subject to the following
additional conditions: 
 (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an
Approved Fund, or an assignment of the entire remaining amount of the assigning Lender’s Loans, the amount of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with
respect to such assignment is delivered to the Administrative Agent) shall (1) be an integral multiple of $1,000,000 and (2) not be less than $5,000,000 unless each of the Borrowers and the Administrative Agent otherwise consent;
provided that no such consent of either Borrower shall be required if an Event of Default under clause (a), (b), (g) or (h) of Article VII has occurred and is continuing; and provided further that
simultaneous 

  
 86 









 
assignments in respect of a Lender and its Approved Funds shall be aggregated for purposes of such requirement; 

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s
rights and obligations under this Agreement; 
 (C) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, payable by either the assignee or the assignor (provided that only one such fee shall be payable in respect of simultaneous
assignments by a Lender and its Approved Funds); and 
 (D) the assignee, if it shall not be a Lender, shall
deliver to the Administrative Agent an Administrative Questionnaire and any Tax forms required by Section 2.15(f). 
 For
purposes of this Section 9.04(b), the terms “Approved Fund” and “CLO” have the following meanings: 

“Approved Fund” means (a) a CLO and (b) with respect to any Lender that is a fund that invests in bank loans
and similar extensions of credit, any other fund that invests in bank loans and similar extensions of credit and is managed by the same investment advisor as such Lender or by an Affiliate of such investment advisor. 

“CLO” means an entity (whether a corporation, partnership, trust or otherwise) that is engaged in making, purchasing,
holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course and is administered or managed by a Lender or an Affiliate of such Lender. 

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the
effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of
the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with
paragraph (c) of this Section. 
 (iv) The Administrative Agent, acting for this purpose as an agent of the
Borrowers, shall maintain at one of its offices a copy of each Assignment and 

  
 87 









 
Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders and the principal amount of the Loans owing to, each Lender pursuant to the terms hereof
from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrowers, the Agents and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a
Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers, any Agent and any Lender, at any reasonable time and from time to time upon reasonable
prior notice. 
 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written
consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for
purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. 
 (c) Any Lender may,
without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible
to the other parties hereto for the performance of such obligations, (C) the Borrowers, the Agents and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations
under this Agreement and (D) such Lender will continue to give prompt attention to and process (including, if required, through discussions with Participants) requests for waivers or amendments hereunder. Any agreement or instrument pursuant to
which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce the Loan Documents and to approve any amendment, modification or waiver of any provision of the Loan Documents; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. The Borrowers
agree that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 (subject to the requirements and limitations therein, including the requirements under Section 2.15(f) (it being understood that the
documentation required under Section 2.15(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that
such Participant (A) agrees to be subject to the provisions of Sections 2.16 and 2.17 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.13 or
2.15, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a 

  
 88 









 
Change in Law that occurs after the Participant acquired the applicable participation. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08
as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrowers, maintain
a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under this Agreement (the “Participant
Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest
in any Commitments, Loans or its other obligations under any Loan Document) except to the extent that such disclosure is necessary to establish that such Commitment, Loan or other obligation is in registered form under Section 5f.103-1(c) of
the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation
for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

 (d) Any Lender may, without the consent of the Borrowers or the Administrative Agent, at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

 SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan
Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and
delivery of the Loan Documents and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that any Agent or any Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is
outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the
transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitments or the termination of this Agreement or any provision hereof. 

  
 89 









 SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and
any separate letter agreements with respect to fees payable to any Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts
hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed
counterpart of a signature page of this Agreement by telecopy or electronic transmission shall be effective as delivery of a manually executed counterpart of this Agreement. 
 SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such
invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision
in any other jurisdiction. 
 SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender, and each of its Affiliates, is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final,
in whatever currency) at any time held and other obligations at any time owing (although such obligations may be unmatured) by such Lender or Affiliate to or for the credit or the account of either Borrower against any of and all the obligations
then due of either Borrower now or hereafter existing under this Agreement. The applicable Lender shall notify the Borrowers and the Administrative Agent of such setoff and application, provided that any failure to give or any delay in giving
such notice shall not affect the validity of any such setoff and application under this Section. The rights of each Lender and its Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that
such Lender and Affiliates may have. 
 SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process; Sovereign
Immunity. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York. 

(b) Each Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the
Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any
Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and 

  
 90 









 
unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal
court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement
or any other Loan Document shall affect any right that any Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against either Borrower or its properties in the courts of any
jurisdiction. 
 (c) Each Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of
this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01.
Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
 SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 SECTION
9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting,
this Agreement. 
 SECTION 9.12. Confidentiality. Each of the Agents and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, trustees, officers, employees and agents, including accountants, legal counsel and other advisors (it
being understood that the Persons to whom such disclosure is made will be informed of the 

  
 91 









 
confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self-regulatory
authority), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any
actual or prospective assignee of or Participant in any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to either Borrower or any
other Loan Party and its obligations, (g) with the consent of the Borrowers, (h) to any credit insurance provider relating to the Borrowers and their Obligations or (i) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section or (ii) becomes available to any Agent or any Lender on a nonconfidential basis from a source other than either Borrower. For the purposes of this Section,
“Information” means all information received from or on behalf of either Borrower relating to either Borrower or its business, other than any such information that is available to any Agent or any Lender on a nonconfidential basis
prior to disclosure by either Borrower. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 

SECTION 9.13. Patriot Act. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies
each Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies each Borrower, which information includes the name and address of each Borrower and other information that
will allow such Lender or the Administrative Agent, as applicable, to identify each Borrower in accordance with the Patriot Act. Each Borrower agrees to provide the Lenders, upon request, with all documentation and other information required from
time to time to be obtained by the Lenders pursuant to applicable “know your customer” and anti-money laundering rules and regulations, including the Patriot Act. 
 SECTION 9.14. No Fiduciary Relationship. The Borrowers, on behalf of themselves and the Subsidiaries, agree that in connection with all aspects of the transactions contemplated hereby and any
communications in connection therewith, the Borrowers, the Subsidiaries and their Affiliates, on the one hand, and the Agents, the Lenders and their Affiliates, on the other hand, will have a business relationship that does not create, by
implication or otherwise, any fiduciary duty on the part of the Agents, the Lenders or their Affiliates, and no such duty will be deemed to have arisen in connection with any such transactions or communications. 

SECTION 9.15. Release of Guarantees. (a) A Subsidiary Guarantor shall automatically be released from its obligations under
the Loan Documents upon the consummation of any transaction permitted by this Agreement as a result of which such 

  
 92 









 
Subsidiary Guarantor ceases to be a Subsidiary; provided that, if so required by this Agreement, the Required Lenders (or such greater number of Lenders as may be required under
Section 9.02) shall have consented to such transaction and the terms of such consent did not provide otherwise. In connection with any release pursuant to this Section, the Administrative Agent shall promptly execute and deliver to any
Subsidiary Guarantor, at such Subsidiary Guarantor’s expense, all documents that such Subsidiary Guarantor shall reasonably request to evidence such termination or release. 

(b) Any execution and delivery of documents pursuant to this Section shall be without recourse to or warranty by the Administrative
Agent. 
 SECTION 9.16. Non-Public Information. (a) Each Lender acknowledges that all information furnished to it
pursuant to this Agreement from the Borrowers or on their behalf and relating to the Borrowers, the Subsidiaries or their respective businesses may include material non-public information concerning the Borrowers and the Subsidiaries or their
securities, and confirms that it has developed compliance procedures regarding the use of material non-public information and that it will handle such material non-public information in accordance with the procedures and applicable law, including
Federal and state securities laws. 
 (b) All such information, including requests for waivers and amendments, furnished by the
Borrowers or the Administrative Agent pursuant to, or in the course of administering, this Agreement will be syndicate-level information, which may contain material non-public information about the Borrowers and the Subsidiaries and their
securities. Accordingly, each Lender represents to the Borrowers and the Administrative Agent that it has identified in its Administrative Questionnaire a credit contact who may receive information that may contain material non-public information in
accordance with its compliance procedures and applicable law, including Federal and state securities laws. 
 ARTICLE X

 Co-Borrower Obligations 
 SECTION 10.01. Joint and Several Liability. (a) In consideration of the establishment of the Commitments and the making of the Loans hereunder, and of the benefits to each of the Borrowers
that are anticipated to result therefrom, each of the Borrowers agrees that, notwithstanding any other provision contained herein or in any other Loan Document, it will be a co-borrower hereunder and shall be fully liable for all of the Obligations,
both severally and jointly with the other Borrower, if any. Accordingly, each Borrower irrevocably agrees with each Lender and the Administrative Agent and their respective successors and assigns that such Borrower will make prompt payment in full
when due (whether at stated maturity, by acceleration, by optional prepayment or otherwise) of the Obligations, strictly in accordance with the terms thereof. Each of the Borrowers hereby further agrees that if any Loan Party shall fail to


  
 93 









 
pay in full when due (whether at stated maturity, by acceleration, by optional prepayment or otherwise) any of the Obligations, then the Borrowers will promptly pay the same, without any demand
or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Obligations, the same will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the
terms of such extension or renewal. Upon the delivery to the Administrative Agent by PXP of a joinder substantially in the form of Exhibit G and other documents and opinions required by Section 4.02(c) or 4.04(c), as applicable, PXP will be a
co-borrower hereunder and shall be fully liable for all of the Obligations, both severally and jointly with the other Borrower, as if PXP had been a Borrower hereunder on the Effective Date. 

SECTION 10.02. Obligations Unconditional. (a) The obligations of each of the Borrowers under Section 10.01 hereof are
absolute and unconditional irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of either Borrower under this Agreement or any other Loan Document, or any substitution, release or exchange of any other
guarantee of or security for any of the Obligations, and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section that the joint and several obligations of the Borrowers hereunder shall be absolute and unconditional under any and all circumstances. Without limiting the generality of the foregoing, it is agreed that
the occurrence of any one or more of the following shall not affect the joint and several liability of either Borrower hereunder: 
 (i) at any time or from time to time, without notice to either Borrower, the time for any performance of or compliance with any of the Obligations shall be extended, or such performance or compliance
shall be waived; 
 (ii) any of the acts mentioned in any of the provisions of this Agreement or any other
agreement or instrument referred to herein or therein shall be done or omitted; or 
 (iii) the maturity of any
of the Obligations shall be accelerated or delayed, or any of the Obligations shall be modified, supplemented or amended in any respect, or any right under this Agreement or any other agreement or instrument referred to herein or therein shall be
waived or any other guarantee of any of the Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with. 
 (b) Certain Waivers. Each of the Borrowers hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Administrative Agent
or any Lender exhaust any right, power or remedy or proceed against either Borrower under this Agreement or any other agreement or instrument referred to herein or therein, or against any other person under any other guarantee of, or security for,
any of the Obligations. 

  
 94 









 (c) Reinstatement. The obligations of each of the Borrowers under this Article X
shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of either Borrower in respect of the Obligations is rescinded or must be otherwise restored by any holder of any of the Obligations, whether as a
result of any proceedings in bankruptcy or reorganization or otherwise. 
 (d) Remedies. Each of the Borrowers agrees
that, as between the Borrowers, in their capacity as co-obligors with joint and several liability, and the Lenders, the obligations of either Borrower under this Agreement may be declared to be forthwith due and payable as provided in Article VII
hereof (and shall be deemed to have become automatically due and payable in the circumstances provided in said Article VII) for purposes of Section 10.01 hereof notwithstanding any stay, injunction or other prohibition preventing such
declaration (or preventing such obligations from becoming automatically due and payable) as against either Borrower and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such
obligations (whether or not due and payable by such Borrower) shall forthwith become due and payable by the other Borrower, in its capacity as co-obligor, for purposes of such Section 10.01. 

(e) Continuing Obligation. Each of the agreements of the Borrowers in this Article X is a continuing agreement and
undertaking, and shall apply to all Obligations whenever arising. 
 (f) Standstill. Upon payment by either of the
Borrowers of any sums as provided under Section 10.01, all rights, if any, of such paying Borrower against the other Borrower arising as a result thereof by way of subrogation or otherwise shall in all respects be irrevocably waived prior to
the indefeasible payment in full in cash of all of the Obligations. 
 (g) Borrower Resignation. PXP will cease to be a
Borrower hereunder (and may thereafter be released from its obligations as a Borrower under this Agreement) (the “Co-Borrower Resignation”) at such time, if any, as (and only for such periods as) PXP (i) no longer has any
obligations in respect of (A) any PXP Indenture Debt and any refinancing Indebtedness in respect thereof or (B) any bank credit facility or other capital market indebtedness, in each case in an amount in excess of $500,000,000 and
(ii) no longer guarantees any obligations of FCX in respect of (and is no longer a co-borrower under) the Revolving Credit Agreement, the MMR Bridge Facility, the PXP Bridge Facility, the Senior Notes or any Other Senior Debt, provided
that for all purposes hereunder and under the other Loan Documents such Co-Borrower Resignation shall only become effective on the date that each of the following conditions has been met (the “Co-Borrower Resignation Date”):

 (i) FCX shall have delivered to the Administrative Agent a written notice of such Co-Borrower Resignation at
least 10 Business Days in advance of (but not more than 30 days in advance of) the Co-Borrower Resignation Date, specifying the intended Co-Borrower Resignation Date; 

  
 95 









 (ii) at the time of and after giving effect to such Co-Borrower Resignation,
the Borrowers shall be in pro forma compliance with Sections 6.01 and 6.02; 
 (iii) at the time of and after
giving effect to such Co-Borrower Resignation, (A) no Default or Event of Default shall have occurred and be continuing, and (B) the representations and warranties of each Loan Party set forth in the Loan Documents shall be true and
correct in all material respects on and as of the intended Co-Borrower Resignation Date, except where such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been true and
correct in all material respects as of such earlier date; and 
 (iv) FCX shall have delivered to the
Administrative Agent a certificate of a Financial Officer of FCX, dated as of the Co-Borrower Resignation Date, certifying as to the matters specified in clauses (ii) and (iii) above and setting forth reasonably detailed calculations
demonstrating compliance with clause (ii) above. 
 ARTICLE XI 

Subsidiary Guarantors 
 SECTION 11.01. Designation of Subsidiary Guarantors. FCX may designate any Subsidiary (other than any Subsidiary that, at the time, is already a Required Subsidiary Guarantor) as a Subsidiary
Guarantor (a “Guarantor Designation”), provided that, for purposes of Sections 6.01 and 6.02, such Designation shall only become effective on the date that each of the following conditions has been met (the “Guarantor
Designation Date”): 
 (a) FCX shall have delivered to the Administrative Agent a written notice of such Guarantor
Designation at least 10 Business Days in advance of (but not more than 30 days in advance of) the Guarantor Designation Date, specifying the Subsidiary subject to the Guarantor Designation; 

(b) at the time of and after giving effect to such Guarantor Designation on the Guarantor Designation Date, the Borrowers shall be in pro
forma compliance with Sections 6.01 and 6.02; 
 (c) such Subsidiary shall have executed and delivered to the Administrative
Agent a Guarantee Agreement (or a supplement thereto), and such Guarantee Agreement shall be in full force and effect; 
 (d)
the Administrative Agent shall have received such documents and certificates as the Administrative Agent or its counsel may reasonably request relating to the organization, existence and good standing of such Subsidiary, the authorization of its
execution of and performance of its obligations under the applicable Guarantee 

  
 96 









 
Agreement, and any other legal matters relating to the Guarantor Designation and reasonably requested by the Administrative Agent, in form and substance reasonably satisfactory to the
Administrative Agent; 
 (e) the Administrative Agent shall have received a favorable opinion (addressed to the Agents and the
Lenders and dated the Guarantor Designation Date) from each of (i) New York counsel and (ii) if reasonably requested by the Administrative Agent (and in all cases where the applicable Subsidiary is organized under the laws of a
jurisdiction outside of the United States of America), local counsel, and such opinions shall be reasonably satisfactory to the Administrative Agent and cover such matters relating to the Guarantor Designation as the Administrative Agent may
reasonably request; and 
 (f) FCX shall have delivered to the Administrative Agent a certificate of a Financial Officer of FCX,
dated as of the Guarantor Designation Date, certifying as to the matters set forth in clauses (b) and (c) above and setting forth reasonably detailed calculations demonstrating compliance with clause (b) above. 

SECTION 11.02. Optional Guarantor Terminations. FCX may elect to terminate any Guarantee of the Obligations by any Subsidiary
Guarantor (a “Guarantor Termination”), provided that, (i) no such Guarantor Termination shall be given or take effect with respect to any Subsidiary that is at the time a Required Subsidiary Guarantor, and (ii) for
all purposes hereunder and under the other Loan Documents, including under any Guarantee Agreement, such Guarantor Termination shall only become effective on the date that each of the following conditions has been met (the “Guarantor
Termination Date”): 
 (a) FCX shall have delivered to the Administrative Agent a written notice of such Guarantor
Termination at least 10 Business Days in advance of (but not more than 30 days in advance of) the Guarantor Termination Date, specifying (i) the Subsidiary subject to such Guarantor Termination and (ii) the intended Guarantor Termination
Date; 
 (b) at the time of and after giving effect to such Guarantor Termination, the Borrowers shall be in pro forma
compliance with Sections 6.01 and 6.02; 
 (c) at the time of and after giving effect to such Guarantor Termination, (i) no
Default or Event of Default shall have occurred and be continuing, and (ii) the representations and warranties of each Loan Party set forth in the Loan Documents shall be true and correct in all material respects on and as of the intended
Guarantor Termination Date, except where such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects as of such earlier date;
and 
 (d) FCX shall have delivered to the Administrative Agent a certificate of a Financial Officer of FCX, dated as of the
Guarantor Termination Date, certifying as to the matters specified in clauses (b) and (c) above and setting forth reasonably detailed calculations demonstrating compliance with clause (b) above.

 Schedule 1.01A 
 Disclosed Matters 
 Environmental. FCX incurred environmental capital expenditures
and other environmental costs (including joint venture partners’ share) to comply with applicable environmental laws and regulations that affect its operations totaling $599 million in 2012. 

FCX subsidiaries that operate in the U.S. are subject to various federal, state and local environmental laws and regulations that govern emissions of air
pollutants; discharges of water pollutants; and generation, handling, storage and disposal of hazardous substances, hazardous wastes and other toxic materials. FCX subsidiaries that operate in the U.S. also are subject to potential liabilities
arising under CERCLA or similar state laws that impose responsibility on current and previous owners and operators of a facility for the cleanup of hazardous substances released from the facility into the environment, including damages to natural
resources, irrespective of when the damage to the environment occurred or who caused it. This cleanup liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site
selected by the transporter. This liability often is shared on a joint and several basis meaning that each responsible party is fully responsible for the cleanup, although in many cases some or all of the other historical owners or operators no
longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX’s acquisition of Phelps Dodge Corporation (name changed to Freeport-McMoRan Corporation, referred to as FMC) in 2007, many of the
subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S. FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX
subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and several state agencies that, under CERCLA or similar state laws and regulations, they may be liable
for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address
environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD). As of December 31, 2012, FCX had more than 100 active remediation projects, including NRD
claims, in the U.S. in 28 states. 
 A summary of changes in environmental obligations for the years ended December 31, 2012 (in millions)
follows: 
  

					
	 Balance at beginning of year
	  	$	1,453	  
	 Accretion expense(a)
	  	 	80	  
	 Additions
	  	 	70	  
	 Reductions(b)
	  	 	(182	) 
	 Spending
	  	 	(199	) 
		  	  
	  
	 
	 Balance at end of year
	  	 	1,222	  
	 Less current portion
	  	 	(186	) 
		  	  
	  
	 
	 Long-term portion
	  	$	1,036	  
		  	  
	  
	 

  

	(a)	Represented accretion of the fair value of environmental obligations assumed in the 2007 acquisition of FMC, which were determined on a discounted cash flow basis.



	(b)	Reductions primarily reflected adjustments for changes in the anticipated scope and timing of environmental remediation projects and the settlement of environmental
matters. 








 Estimated environmental cash payments (on an undiscounted and unescalated basis) total $186 million in 2013,
$225 million in 2014, $124 million in 2015, $107 million in 2016, $110 million in 2017 and $1.7 billion thereafter. The amounts and timing of these estimated payments could change as a result of changes in regulatory requirements, changes in scope
and timing of remediation activities, the settlement of environmental matters and as actual spending occurs. 
 FCX was required to record
FMC’s environmental obligations at fair value on the acquisition date in accordance with business combination accounting guidance. Significant adjustments to these obligations may occur in the future. At December 31, 2012, FCX’s
environmental obligations totaled $2.4 billion on an undiscounted and unescalated basis (compared with $1.2 billion recorded on the balance sheet, which included environmental obligations assumed in the FMC acquisition at fair value). FCX estimates
it is reasonably possible that these obligations could range between $2.1 billion and $2.7 billion on an undiscounted and unescalated basis. 

FCX believes that there may be potential claims for recovery from third parties, including the U.S. government and other PRPs. These potential recoveries
are not recognized unless realization is considered probable. 
 At December 31, 2012, the most significant environmental obligations were
associated with the Pinal Creek site in Arizona; the Newtown Creek site in New York City; historical smelter sites principally located in Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania; and uranium mining sites in the western U.S. The
recorded environmental obligations for these sites totaled $1.0 billion at December 31, 2012. A discussion of these sites follows. 

Pinal Creek. The Pinal Creek site was listed under the Arizona Department of Environmental Quality’s (ADEQ) Water Quality Assurance Revolving
Fund program in 1989 for contamination in the shallow alluvial aquifers within the Pinal Creek drainage near Miami, Arizona. Since that time, environmental remediation was performed by members of the Pinal Creek Group (PCG), consisting of FMC Miami,
Inc. (Miami), a wholly owned subsidiary of FMC, and two other companies. In 1998, the District Court approved a Consent Decree between the PCG members and the state of Arizona resolving all matters related to an enforcement action contemplated by
the state of Arizona against the PCG members with respect to groundwater contamination. The Consent Decree committed the PCG members to complete the remediation work outlined in the Consent Decree, and that work continues at this time and is
expected to continue for many years in the future. Miami also was a party to litigation entitled Pinal Creek Group, et al. v. Newmont Mining Corporation, et al., United States District Court, District of Arizona, Case No. CIV 91-1764 PHX DAE
(LOA), filed on May 1, 1991. Pursuant to a settlement in 2010, Miami paid $40 million to certain members of the PCG to settle the allocation of previously incurred costs, and agreed to take full responsibility for future groundwater remediation
at the Pinal Creek site, with limited exceptions. The settlement did not result in a change to the obligation, which was estimated at fair value when assumed in the FMC acquisition. During 2011, the obligation was increased by $31 million to reflect
changes in remediation capping designs that incorporate best practices for side slope regrading and cap thickness. 







 Newtown Creek. From the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of
FMC, operated a smelter, and from the 1930s until 1984, it operated a refinery on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms part of the boundary between Brooklyn and Queens in New York City. Heavy
industrialization along the banks of the creek and discharges from the City of New York’s sewer system over more than a century resulted in significant environmental contamination of the waterway. The New York Attorney General previously
notified several companies, including PDRC, about possible obligations to clean up contaminated sediments in the creek. In March and April 2010, EPA notified PDRC and five others that EPA considers them to be PRPs under CERCLA. The notified parties
began working with EPA to identify other PRPs, and EPA proposed that the notified parties perform a Remedial Investigation/Feasibility Study (RI/FS) at their expense and reimburse EPA for its oversight costs. EPA is not expected to propose a remedy
until after a RI/FS is completed, which is expected to take several years. On September 29, 2010, EPA designated the creek as a Superfund site. Effective July 18, 2011, PDRC and five other parties entered an Administrative Order on Consent
(AOC) to perform a RI/FS to assess the nature and extent of environmental contamination in the creek and identify potential remedial options. The parties’ RI/FS work under the AOC and their identification of other PRPs are ongoing. FCX’s
financial obligation for this matter was estimated at fair value when it was assumed in the FMC acquisition and is included in FCX’s aggregate environmental obligations. The actual costs of fulfilling this remedial obligation and the allocation
of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remediation remedy ultimately selected by EPA and related allocation determinations. Depending on the overall cost and the portion allocated to PDRC, that
share could be material to FCX. 
 Historical Smelter Sites. FMC and its predecessors at various times owned or operated copper and zinc
smelters in several states, including Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania. For some of these smelter sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating
and, if appropriate, remediating environmental conditions associated with the smelters. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate site conditions
associated with the smelters. The historical smelter sites are in various stages of assessment and remediation. The two most significant environmental obligations for historical smelter sites relate to Blackwell, Oklahoma, and Bisbee, Arizona.
Adjustments to the environmental obligations for historical smelter sites, which principally were estimated at fair value when assumed in the FMC acquisition, totaled a reduction of $47 million in 2012, primarily because of changes in estimated
timing of obligations, and an increase of $36 million in 2011, primarily at the Blackwell, Oklahoma, site (refer to discussion below). 

Blackwell. From 1918 to 1974, Blackwell Zinc Company, Inc. (BZC), an indirect subsidiary of FCX, owned and operated a zinc smelter in Blackwell,
Oklahoma. In 1974, the smelter was demolished and the property deeded to the Blackwell Industrial Authority. Pursuant to an administrative order with the state of Oklahoma, BZC undertook remedial actions in Blackwell in 1996 and 1997, including
sampling the nearby residential and commercial properties, and removing soils on properties that were found to have metal concentrations above state-established cleanup standards. From 1997 to 2003, BZC investigated the nature and extent of
groundwater contamination potentially attributable to the former smelter and evaluated options 







 
for remedying such contamination. In 2003, the state of Oklahoma adopted a cleanup plan requiring the installation of a groundwater extraction and treatment system and the closure of domestic
groundwater wells within the groundwater plume area. BZC completed the construction of a groundwater extraction and treatment system, with system startup and initial discharge of treated water occurring in October 2010. 

Between 2007 through 2012, FCX, on behalf of BZC, completed a voluntary soil remediation program by inviting property owners in and around Blackwell to
have soil at their properties sampled for the presence of smelter-related contaminants, and offering to remediate properties whose soils were found to have metal concentrations above state-established cleanup standards. As part of this program, FCX
sampled soils on approximately 90 percent of the residential properties in Blackwell and remediated soils on about 600 properties. All of these soil sampling and remediation activities were coordinated with, and supervised by, the state of Oklahoma.

 On May 23, 2012, the Board of Commissioners of Kay County, Oklahoma, filed suit in Oklahoma District Court against FCX and several
affiliates, including BZC, entitled Board of Commissioners of the County of Kay, Oklahoma v. Freeport-McMoRan Copper & Gold Inc., et al., United States District Court, Western District of Oklahoma, Case No. 5:12-cv-00601-C. On
May 25, 2012, the case was removed to the United States District Court for the Western District of Oklahoma, and trial is set for October 2013. The suit alleges BZC permitted large quantities of smelter waste to be used as road building and
fill material throughout Kay County over a period of decades and seeks unspecified financial assistance for removing and covering much of the material, and unspecified damages for the alleged public nuisance created by the presence of the material.
FCX has asserted a counter claim against Kay County for contribution under CERCLA. Separate from the litigation, in fourth-quarter 2012, BZC entered into a Consent Agreement and Final Order with the Oklahoma Department of Environmental Quality and
Kay County to conduct an assessment of smelter material present on Kay County’s roads, bridges and associated rights-of-way. Sampling is expected to be completed in 2013. 
 Bisbee. From the 1880s until 1975, FMC and certain predecessor and subsidiary entities operated a copper mine near Bisbee, Arizona. A series of smelters operated in Bisbee from approximately 1879
through 1908. In 2000, FMC entered the Bisbee area into the Arizona Voluntary Remediation Program (VRP) administered by ADEQ. In 2008, FMC expanded the VRP project to include other communities near Bisbee and commenced a voluntary community outreach
program inviting property owners to have soils at their properties sampled for the presence of smelter and mine-related metals. For property owners whose soils are found to have metal concentrations above ADEQ established cleanup standards, FMC has
offered to remove the impacted soils and replace them with clean soils. For those property owners who requested sampling, approximately 40 percent require some level of cleanup. At December 31, 2012, approximately 60 percent of owners who
agreed to have soil cleanup on their properties was completed. 
 Uranium Mining Sites. During a period between 1940 and the early 1970s,
certain FMC predecessor entities were involved in uranium exploration and mining in the western U.S. Similar exploration and mining activities by other companies have caused environmental impacts that have warranted remediation, and EPA and local
authorities are currently evaluating the need 







 
for significant cleanup activities in the region. To date, FMC has undertaken remediation at a limited number of sites associated with these predecessor entities. An initiative to gather
additional information about sites in the region is ongoing, and information gathered under this initiative was submitted to EPA Region 9 during the second and third quarters of 2008 and the fourth quarter of 2009 in response to an information
request by EPA regarding uranium mining activities on Navajo Nation properties. FCX utilized the results of FMC’s remediation experience, in combination with historical and updated information to initially estimate the fair value of
uranium-related liabilities assumed in the FMC acquisition. 
 Asset Retirement Obligations (AROs). FCX’s ARO cost estimates are
reflected on a third-party cost basis and comply with FCX’s legal obligation to retire tangible, long-lived assets. A summary of changes in FCX’s AROs for the year ended December 31, 2012 (in millions) follows: 

 

					
	 Balance at beginning of year
	  	$	 921	  
	 Liabilities incurred
	  	 	6	  
	 Revisions to cash flow estimates (a)
	  	 	211

	 Long-term portion
	  	$	1,091	  
		  	  
	  
	 

  

	(a)	Revisions to cash flow estimates were primarily related to updated closure plans that included revised cost estimates and accelerated timing of certain closure
activities. 

 ARO costs may increase or decrease significantly in the future as a result of changes in regulations, changes in
engineering designs and technology, permit modifications or updates, changes in mine plans, inflation or other factors and as actual reclamation spending occurs. ARO activities and expenditures generally are made over an extended period of time
commencing near the end of the mine life; however, certain reclamation activities may be accelerated if legally required or if determined to be economically beneficial. 
 Legal requirements in New Mexico, Arizona and Colorado require financial assurance to be provided for the estimated costs of reclamation and closure, including groundwater quality protection programs. FCX
has satisfied financial assurance requirements by using a variety of mechanisms, such as performance guarantees, financial capability demonstrations, trust funds, surety bonds, letters of credit and collateral. The applicable regulations specify
financial strength tests that are designed to confirm a company’s or guarantor’s financial capability to fund estimated reclamation and closure costs. The amount of financial assurance FCX is required to provide will vary with changes in
laws, regulations and reclamation and closure requirements, and cost estimates. At December 31, 2012, FCX’s financial assurance obligations associated with these closure and reclamation costs totaled $946 million, of which approximately
$582 million was in the form of guarantees issued by FCX and financial capability demonstrations. At December 31, 2012, FCX had trust assets totaling $161 million, which are legally restricted to fund a portion of its AROs for properties in New
Mexico as required by New Mexico regulatory authorities. 







 New Mexico Environmental and Reclamation Programs. FCX’s New Mexico operations are regulated
under the New Mexico Water Quality Act and regulations adopted under that act by the Water Quality Control Commission (WQCC). The New Mexico Environment Department (NMED) has required each of these operations to submit closure plans for NMED’s
approval. The closure plans must include measures to assure meeting groundwater quality standards following the closure of discharging facilities and to abate any groundwater or surface water contamination. In March 2009, the Tyrone operation
appealed the WQCC Final Order, dated February 4, 2009, regarding location of the “places of withdrawal of water,” a legal criterion used to determine where groundwater quality standards must be met at FCX’s New Mexico mining
sites. In December 2010, Tyrone entered into a settlement agreement with NMED that calls for a stay of the appeal while NMED and the WQCC complete several administrative actions, including renewal of Tyrone’s closure permit consistent with the
terms of the settlement, review and approval of a groundwater abatement plan and adoption of alternative abatement standards, and adoption of new groundwater discharge permit rules for copper mines. If the administrative actions are concluded
consistent with the terms of the settlement agreement within the period of the stay, then Tyrone will move to dismiss the appeal. In December 2012, Tyrone and NMED agreed to extend the period to conclude the administrative actions through
December 31, 2013. The Court of Appeals also extended the stay for another year. Finalized closure plan requirements, including those resulting from the actions to be taken under the settlement agreement, could result in increases in the
Tyrone, Chino and Cobre closure costs. 
 FCX’s New Mexico operations also are subject to regulation under the 1993 New Mexico Mining Act
(the Mining Act) and the related rules that are administered by the Mining and Minerals Division (MMD) of the New Mexico Energy, Minerals and Natural Resources Department. Under the Mining Act, mines are required to obtain approval of plans
describing the reclamation to be performed following cessation of mining operations. At December 31, 2012, FCX had accrued reclamation and closure costs of $476 million for its New Mexico operations. As stated above, additional accruals may be
required based on the state’s review of FCX’s updated closure plans and any resulting permit conditions, and the amount of those accruals could be material. 
 Arizona Environmental and Reclamation Programs. FCX’s Arizona properties are subject to regulatory oversight in several areas. ADEQ has adopted regulations for its aquifer protection permit
(APP) program that require permits for, among other things, certain facilities, activities and structures used for mining, concentrating and smelting and require compliance with aquifer water quality standards at an applicable point of compliance
well or location. The APP program also may require mitigation and discharge reduction or elimination of some discharges. 
 An application for
an APP requires a description of a closure strategy that will meet applicable groundwater protection requirements following cessation of operations and an estimate of the cost to implement the closure strategy. An APP may specify closure
requirements, which may include post-closure monitoring and maintenance. A more detailed closure plan must be submitted within 90 days after a permitted entity notifies ADEQ of its intent to cease operations. A permit applicant must demonstrate its
financial ability to meet the closure costs estimated in the APP. 







 Portions of Arizona mining facilities that operated after January 1, 1986, also are subject to the
Arizona Mined Land Reclamation Act (AMLRA). AMLRA requires reclamation to achieve stability and safety consistent with post-mining land use objectives specified in a reclamation plan. Reclamation plans must be approved by the State Mine Inspector
and must include an estimate of the cost to perform the reclamation measures specified in the plan. FCX will continue to evaluate options for future reclamation and closure activities at its operating and non-operating sites, which are likely to
result in adjustments to FCX’s ARO liabilities. At December 31, 2012, FCX had accrued reclamation and closure costs of $240 million for its Arizona operations. 
 Colorado Reclamation Programs. FCX’s Colorado operations are regulated by the Colorado Mined Land Reclamation Act (Reclamation Act) and regulations promulgated thereunder. Under the
Reclamation Act, mines are required to obtain approval of reclamation plans describing the reclamation of lands affected by mining operations to be performed during mining or upon cessation of mining operations. As of December 31, 2012, FCX had
accrued reclamation and closure costs of $47 million for its Colorado operations. 
 Chilean Reclamation and Closure Programs. In July
2011, the Chilean senate passed legislation regulating mine closure, which establishes new requirements for closure plans and became effective in November 2012. FCX’s Chilean operations will be required to update closure plans and provide
financial assurance for these obligations. FCX cannot predict at this time the cost of these closure plans or the levels or forms of financial assurance that may be required. Revised closure plans for the Chilean mine sites are due in November 2014.
At December 31, 2012, FCX had accrued reclamation and closure costs of $54 million for its Chilean operations. 
 Peruvian Reclamation
and Closure Programs. Cerro Verde is subject to regulation under the Mine Closure Law administered by the Peruvian Ministry of Energy and Mines. Under the closure regulations, mines must submit a closure plan that includes the reclamation
methods, closure cost estimates, methods of control and verification, closure and post-closure plans and financial assurance. The updated closure plan for the Cerro Verde mine expansion must be submitted to the Peruvian regulatory authorities in
December 2014. At December 31, 2012, Cerro Verde had accrued reclamation and closure costs of $89 million. 
 PT Freeport Indonesia
Reclamation and Closure Programs. The ultimate amount of reclamation and closure costs to be incurred at PT Freeport Indonesia’s operations will be determined based on applicable laws and regulations and PT Freeport Indonesia’s
assessment of appropriate remedial activities in the circumstances, after consultation with governmental authorities, affected local residents and other affected parties and cannot currently be projected with precision. Estimates of the ultimate
reclamation and closure costs PT Freeport Indonesia will incur in the future involve complex issues requiring integrated assessments over a period of many years and are subject to revision over time as more complete studies are performed. Some
reclamation costs will be incurred during mining activities, while most closure costs and the remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue for approximately 30 years. At
December 31, 2012, PT Freeport Indonesia had accrued reclamation and closure costs of $195 million and a long-term receivable for Rio Tinto’s share of the obligation of $18 million (included in long-term receivables). 







 In 1996, PT Freeport Indonesia began contributing to a cash fund ($16 million balance at December 31,
2012) designed to accumulate at least $100 million (including interest) by the end of its Indonesia mining activities. PT Freeport Indonesia plans to use this fund, including accrued interest, to pay mine closure and reclamation costs. Any costs in
excess of the $100 million fund would be funded by operational cash flow or other sources. 
 In December 2010, the President of Indonesia
issued a regulation regarding mine reclamation and closure, which requires a company to provide a mine closure guarantee in the form of a time deposit placed in a state-owned bank in Indonesia. In accordance with its Contract of Work, PT Freeport
Indonesia is working with the Department of Energy and Mineral Resources to review these requirements, including discussion of other options for the mine closure guarantee. In December 2009, PT Freeport Indonesia submitted its revised mine closure
plan to the Department of Energy and Mineral Resources for review and has addressed comments received during the course of this review process. 

Litigation. 
 Asbestos Claims.
Since approximately 1990, FMC and various subsidiaries have been named as defendants in a large number of lawsuits that claim personal injury either from exposure to asbestos allegedly contained in electrical wire products produced or marketed many
years ago or from asbestos contained in buildings and facilities located at properties owned or operated by FMC affiliates, or from alleged asbestos in talc products. Many of these suits involve a large number of codefendants. Based on litigation
results to date and facts currently known, FCX believes there is a reasonable possibility that losses may have been incurred related to these matters; however, FCX also believes that the amounts of any such losses, individually or in the aggregate,
are not material to its consolidated financial statements. There can be no assurance, however, that future developments will not alter this conclusion. 
 Yonkers Site. From 1932 until 1984, FMC owned and operated a cable manufacturing facility on the Hudson River in Yonkers, New York. FMC sold that operation in 1984, and it was subsequently sold to
BICC Cables Corporation (BICC). BICC closed the facility in 1996. In 2005, Blackacre Partners OPS, LLC (Blackacre) began environmental cleanup work at the site using funding provided by FMC and BICC. One Point Street, Inc. (OPS), a real estate
developer, has current title to the site. 
 On September 9, 2011, OPS filed a complaint in the United States District Court for the
Southern District of New York, which it amended on March 1, 2012. The amended complaint alleged that FMC, BICC and Blackacre failed to timely and diligently complete remediation of the site in breach of alleged obligations under CERCLA and New
York Environmental Conservation Law, and under the contractual agreements among the parties. In fourth-quarter 2012, this matter was settled, and OPS will be completing the limited remaining cleanup work at the site using funds provided by FMC and
BICC. 







 Columbian Chemicals Company (Columbian) Claims. Columbian, formerly a subsidiary of FMC, has notified
FCX of various indemnification claims arising out of the 2005 agreement pursuant to which Columbian was sold. The principal outstanding claims relate to (1) multiple mass tort suits pending against Columbian in West Virginia state court for
alleged personal injury and property damage resulting from exposure to carbon black (the Carbon Black claims) and (2) an investigation being conducted by EPA of potential Clean Air Act violations during the period Columbian was owned by FMC
(the Clean Air Act matter). In April 2012, Columbian filed suit in New York state court (Columbian Chemicals Company and Columbian Chemicals Acquisition LLC v. Freeport-McMoRan Corporation f/k/a Phelps Dodge Corporation, County of New York,
Supreme Court of the State of New York, Index No. 600999/2010), that alleged, among other things, that the Carbon Black claims are the responsibility of FMC, and are not subject to the aggregate cap under the 2005 agreement pursuant to which
Columbian was sold. In July 2012, FCX and Columbian reached a settlement pursuant to which the litigation was dismissed with prejudice and all outstanding disputes regarding the extent of FCX’s indemnity obligations to Columbian were fully
resolved. Under the terms of the settlement, FCX’s remaining possible exposure is to indemnify Columbian for incurred losses related only to the Carbon Black claims and the Clean Air Act matter. The cap, net of amounts reserved and paid,
totaled $122 million at December 31, 2012. FMC cannot estimate Columbian’s exposure, if any, for the Carbon Black claims or the Clean Air Act matter. 
 Shareholder Litigation. Thirteen derivative actions challenging the PXP merger and/or the MMR merger were filed on behalf of FCX by purported FCX stockholders. Ten were filed in the Court of
Chancery of the State of Delaware and three were filed in the Superior Court of the State of Arizona, County of Maricopa. On January 25, 2013, the Delaware Court of Chancery consolidated the Delaware actions into a single action, In Re
Freeport-McMoRan Copper & Gold Inc. Derivative Litigation, No. 8145-VCN. On January 17, 2013, the Arizona Superior Court consolidated two of the Arizona actions into In Re Freeport-McMoRan Derivative Litigation, No.
CV2012-018351. A third Arizona complaint, Harris v. Adkerson et al., No. CV2013-004163, filed on January 16, 2013, has not yet been consolidated. The actions name some or all of the following as defendants: the directors and certain
officers of FCX, two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions allege, among other things, that the FCX directors breached their fiduciary duties to FCX stockholders because
they, among other things, pursued their own interests at the expense of stockholders in approving the PXP and MMR mergers. The complaints also allege that some or all of the following parties aided and abetted the wrongful acts allegedly committed
by the directors and certain officers of FCX: two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions seek as relief, among other things, an injunction barring or rescinding both the PXP
merger and the MMR merger and requiring submission of the proposed PXP merger and MMR merger to a vote of FCX stockholders, damages, and attorneys’ fees and costs. 
 Three putative class actions challenging the PXP merger were filed on behalf of PXP stockholders in the Court of Chancery of the State of Delaware. On January 15, 2013, the Court of Chancery
consolidated the actions into a single action, In Re Plains Exploration & Production Company Stockholder Litigation, No. 8090-VCN. The action names as defendants PXP, the directors of PXP, FCX, and an FCX subsidiary. The action
alleges that PXP’s directors breached 







 
their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with respect to the merger, and that
FCX and an FCX subsidiary aided and abetted the breach of fiduciary duties by PXP’s directors. The action seeks as relief an injunction barring or rescinding the PXP merger, damages, and attorneys’ fees and costs. 

In addition, ten putative class actions challenging the MMR merger were filed on behalf of MMR stockholders. Nine were filed in the Court of Chancery of
the State of Delaware. On January 25, 2012, the Court of Chancery consolidated the actions into a single action, In Re McMoRan Exploration Co. Stockholder Litigation, No. 8132-VCN. One action was also filed in the Civil District
Court for the Parish of Orleans of the State of Louisiana: Langley v. Moffett et al., No. 2012-11904, filed December 19, 2012. Each of the actions names some or all of the following as defendants, in addition to MMR and its
directors: FCX, subsidiaries of FCX, and PXP. The actions allege that MMR’s directors breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize
stockholder value with respect to the merger, and that PXP, FCX, or both, aided and abetted the breach of fiduciary duty by MMR’s directors. The Delaware action also asserts claims derivatively on behalf of MMR. The actions seek, among other
things, injunctive relief barring or rescinding the MMR merger, damages, and attorneys’ fees and costs. 
 FCX intends to vigorously defend
itself in these matters. 
 Tax Matters. Cerro Verde Tax Proceedings. SUNAT, the Peruvian national tax authority, has assessed
mining royalties on materials processed by the Cerro Verde concentrator that commenced operations in late 2006. These assessments cover the period October 2006 to December 2007 and the years 2008 and 2009. SUNAT has issued rulings denying Cerro
Verde’s protest of the assessments. Cerro Verde has appealed these decisions and currently has three cases pending before the Peruvian Tax Court. Cerro Verde is challenging these royalties because it believes its stability agreement provides an
exemption for all minerals extracted from its mining concession, irrespective of the method used for processing those minerals. Although FCX believes its interpretation of the stability agreement is correct, if Cerro Verde is ultimately found
responsible for these assessments, it will also be liable for interest, which accrues at rates that range from approximately 7 to 18 percent based on the year accrued and the currency in which the amounts would be payable. At December 31, 2012,
the aggregate amount of the assessments, including interest and penalties, totaled $218 million. SUNAT may continue to assess mining royalties annually until this matter is resolved by the Peruvian Tax Tribunal. 

Cerro Verde is also challenging various income and value-added tax assessments from SUNAT covering the years 2002 through 2008 and has cases pending
before the Peruvian Tax Court. At December 31, 2012, the approximate amount of these assessments, including interest and penalties, totaled $180 million. 







 Indonesia Tax Matters. The Indonesian tax authorities issued assessments for various audit exceptions
on PT Freeport Indonesia’s tax returns as follows (in millions):

 PT Freeport Indonesia has filed objections to the assessments because it believes it has properly paid its taxes. During
first-quarter 2012, PT Freeport Indonesia’s objections to the assessments related to 2005 were substantially all rejected by the Indonesian tax authorities and, in May 2012, appeals were filed with the Indonesian Tax Court. As of
December 31, 2012, PT Freeport Indonesia has paid $182 million (of which $148 million is included in long-term receivables) for the disputed tax assessments related to 2005, 2006 and 2007. PT Freeport Indonesia is working with the Indonesian
tax authorities to resolve these matters and expects to receive additional assessments from the Indonesian tax authorities for their audit of its 2008 tax return. 
 In December 2009, PT Freeport Indonesia was notified by the Large Taxpayer’s Office of the Government of Indonesia of its view that PT Freeport Indonesia is obligated to pay value added taxes on
certain goods imported after the year 2000. The amount of such taxes and related penalties under this view would be significant. PT Freeport Indonesia believes that, pursuant to the terms of its Contract of Work, it is only required to pay value
added taxes on these types of goods imported after December 30, 2009. PT Freeport Indonesia has not received a formal assessment and is working with the applicable government authorities to resolve this matter. 

Letters of Credit, Bank Guarantees and Surety Bonds. Letters of credit and bank guarantees totaled $98 million at December 31, 2012,
primarily for reclamation and environmental obligations, workers’ compensation insurance programs, tax and customs obligations, and other commercial obligations. In addition, FCX had surety bonds totaling $159 million at December 31, 2012,
associated with reclamation and closure ($137 million – see discussion above), self-insurance bonds primarily for workers’ compensation ($18 million) and other bonds ($4 million). 
 Insurance. FCX purchases a variety of insurance products to mitigate potential losses. The various insurance products typically have specified deductible amounts or self-insured retentions and
policy limits. FCX generally is self-insured for U.S. workers’ compensation, but purchases excess insurance up to statutory limits. An actuarial analysis is performed twice a year for various FCX casualty programs, including workers’
compensation, to estimate required insurance reserves. Insurance reserves totaled $52 million at December 31, 2012, which consisted of a current portion of $8 million (included in accounts payable and accrued liabilities) and a long-term
portion of $44 million (included in other liabilities). 
 FCX maintains property damage and business interruption insurance related to its
operations. FCX and its insurers entered into an insurance settlement agreement in December 2012. The insurers agreed to pay an aggregate of $63 million, including $4 million for PT Freeport Indonesia’s joint venture partner’s interest,
for the settlement of the insurance claim for business interruption and property damage relating to the 2011 incidents affecting PT Freeport Indonesia’s concentrate pipelines. As a result of the settlement, FCX recorded a gain of $59 million
($31 million to net income attributable to FCX common stockholders). 







 As of the earlier of the Combined Closing Date and the PXP Closing Date, the following shall be included on
this Schedule 1.01A: 
 The environmental matters, and related actions, suits and proceedings, disclosed in (i) the Annual
Report on Form 10-K of Plains Exploration & Production Company for the fiscal year ended December 31, 2011 filed with the SEC on February 24, 2012 and amended on February 24, 2012, (ii) the Registration Statement on Form
S-4 of FCX filed with the SEC on December 28, 2012 and (iii) the Amendment No. 1 to the Registration Statement on Form S-4 of FCX filed with the SEC on February 8, 2013. 
 As of the earlier of the Combined Closing Date and the MMR Closing Date, the following shall be included on this Schedule 1.01A: 
 Oil and Gas Operations. McMoRan has $118.9 million of estimated commitments related to its planned oil and gas exploration and development activities, including costs related to projects currently
in progress, inventory purchase commitments and other exploration expenditures. Included in this amount is $16.0 million of expenditures for drilling rig contract charges anticipated to be expended over the next year which McMoRan expects to share
with its partners in its exploration program. 
 Long-Term Contracts and Operating Leases. McMoRan’s primary
operating leases involve renting office space in two buildings in Houston, Texas, which expire in April 2014 and July 2014, and office space in Lafayette, Louisiana, which expires in November 2015. At December 31, 2012, McMoRan’s total
minimum annual contractual charges aggregated $4.1 million, with payments totaling $2.5 million in 2013, $1.5 million in 2014 and $0.1 million in 2015. Rent expense, including rent allocated to McMoRan by FM Services (Note 14), totaled $3.0 million
in 2012, $3.0 million in 2011 and $3.0 million in 2010. 
 Other Liabilities. Freeport Energy has a contractual obligation
to reimburse a third party a portion of its postretirement benefit costs relating to certain retired former sulphur employees of Freeport Energy. This contractual obligation totaled $1.8 million at December 31, 2012 and $1.5 million at
December 31, 2011, including $0.5 million and $0.7 million in current liabilities from discontinued operations, respectively. A third-party actuarial consultant assesses the estimated related future costs associated with this contractual
liability on an annual basis using current health care trend costs and incorporating changes made to the underlying benefit plans of the third party. The assessment at year end 2012 used an initial health care cost trend rate of 8.0 percent in 2012
decreasing ratably to 4.5 percent in 2029. The assessment at year end 2011 used an initial health care cost trend rate of 7.9 percent in 2011 decreasing ratably to 4.5 percent in 2028. McMoRan applied a discount rate of 8.5 percent at
December 31, 2012 and 2011 to the consultant’s future cost estimates. McMoRan increased the liability by $0.8 million at December 31, 2012 primarily due to estimated increases in future health claim costs resulting from higher than
expected actual health claim reimbursements and higher health trend costs. McMoRan reduced the liability by $1.6 million at December 31, 2011, due to 







 
lower than expected actual health claim reimbursements at that time, partially offset by higher health trend costs. Future revisions to this estimate resulting from changes in assumptions or
actual results varying from projected results will be recorded in earnings. 
 Environmental and Reclamation. McMoRan has
made, and will continue to make, expenditures for the protection of the environment. McMoRan is subject to contingencies as a result of environmental laws and regulations. Present and future environmental laws and regulations applicable to
McMoRan’s operations could require substantial capital expenditures or could adversely affect its operations in other ways that cannot be predicted at this time. Cumulative legal fees and related settlement amounts incurred with respect to
historical oil and gas liabilities McMoRan assumed from IMC Global since 2002 total approximately $1.2 million. No additional amounts have been recorded because no specific liability requiring McMoRan to fund any material future amounts has been
identified and assessed to be probable. 
 Since 2007 McMoRan has funded over $430 million of reclamation costs to settle a
significant portion of the asset retirement obligations assumed in an oil and gas property acquisition in 2007, including certain properties damaged in the 2008 hurricanes. McMoRan’s estimates of existing asset retirement obligations involve
inherent uncertainties and are subject to change over time as a result of several factors, including, without limitation, changes in the industry’s regulatory environment, changes in the cost and availability of required equipment and expertise
to complete the work, changes in timing, and changes in scope that are identified as reclamation projects progress. McMoRan revises its reclamation estimates, as appropriate, when such changes in estimates become known. 

The results from these reclamation activities as well as information obtained from other industry sources indicate that the cost to
conduct reclamation projects in the offshore Gulf of Mexico region has risen in recent years, particularly since the occurrence of the 2010 Deepwater Horizon incident. As a result, McMoRan re-assessed the estimates of substantially all of its
oil and gas property asset retirement obligations in 2011. As a result of this assessment McMoRan revised its estimates related to certain, ongoing and/or near term reclamation projects resulting in an increase to accretion expense of approximately
$57.3 million. Approximately $19.8 million of these charges were reimbursed to McMoRan under its insurance policies related to damage restoration costs resulting from the 2008 hurricane events. In addition, McMoRan also revised its estimates related
to certain longer term producing properties resulting in adjustments that increased property, plant and equipment by approximately $54.6 million. 
 Revisions made for certain properties depending upon the respective circumstances include consideration of the following: (1) the inclusion of estimates for new properties; (2) changes in the
projected timing of certain reclamation costs because of changes in the estimated timing of the depletion of the related proved reserves for McMoRan’s oil and gas properties and new estimates for the timing of the reclamation for the structures
comprising the MPEHTM project and former sulphur facilities at Main Pass; (3) changes in the reclamation costs based on revised estimates of future reclamation work to be performed; and (4) when applicable, changes in McMoRan’s
credit-adjusted, risk-free 







 
interest rate. McMoRan’s credit adjusted, risk-free interest rates ranged from 4.1 percent to 6.4 percent at December 31, 2012, 4.1 percent to 6.4 percent at December 31, 2011 and
4.6 percent to 9.9 percent at December 31, 2010. At December 31, 2012, McMoRan’s estimated undiscounted reclamation obligations, including inflation and market risk premiums, totaled $369.4 million, including $41.4 million associated
with its remaining sulphur obligations. A rollforward of McMoRan’s consolidated discounted asset retirement obligations (including both current and long term liabilities) follows (in thousands):

 At December 31, 2012, McMoRan had $4.9 million in restricted investments associated with third party prepayments of their share of future abandonment costs and $56.4 million held in escrow associated
with the surety funding requirements in favor of a third party related to a portion of the reclamation obligations assumed in a 2007 oil and gas property acquisition. McMoRan is required to make quarterly installment payments under these
requirements totaling $15 million annually through July 2010 and $5.0 million a year thereafter until certain requirements under the arrangement are met. These restricted funds are classified as long-term restricted cash in the accompanying
consolidated balance sheets. 







 Litigation. 
 Between December 11, 2012 and December 26, 2012, ten putative class actions challenging the FCX/MMR merger were filed on behalf of all McMoRan stockholders by purported McMoRan stockholders.
Nine were filed in the Court of Chancery of the State of Delaware (the “Court of Chancery”). On January 25, 2013, the Court of Chancery consolidated the actions into a single action, In re McMoRan Exploration Co. Stockholder
Litigation, No. 8132-VCN. One action was also filed on December 19, 2012 in the Civil District Court for the Parish of Orleans of the State of Louisiana, Langley v. Moffett et al., No. 2012-11904. The defendants in these lawsuits
include McMoRan, members of the McMoRan board of directors, FCX, INAVN Corp., a wholly-owned subsidiary of FCX (the “merger sub”), another subsidiary of FCX, the Gulf Coast Ultra Deep Royalty Trust and PXP. The lawsuits allege, among other
things, that members of the McMoRan board of directors breached their fiduciary duties to McMoRan’s stockholders because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder
value with respect to the merger, and that FCX, the merger sub and PXP aided and abetted that breach of fiduciary duties. The consolidated Delaware action also asserts claims derivatively on behalf of McMoRan. These lawsuits seek, among other
things, an injunction barring or rescinding the FCX/MMR merger, damages, and attorney’s fees and costs. 
 In addition,
between December 14, 2012 and January 16, 2013, thirteen derivative actions challenging the FCX/MMR merger and/or the FCX/PXP merger were filed on behalf of FCX by purported FCX stockholders. Ten were filed in the Court of Chancery and
three were filed in the Superior Court of the State of Arizona, County of Maricopa (the “Arizona Superior Court”). On January 25, 2013, the Court of Chancery consolidated the Delaware actions into a single action, In re
Freeport-McMoRan Copper & Gold, Inc. Derivative Litigation, No. 8145-VCN. On January 17, 2013, the Arizona Superior Court consolidated two of the Arizona actions into In re Freeport-McMoRan Derivative Litigation, No.
CV2012-018351. A third Arizona complaint, Harris v. Adkerson et al., No. CV2013-004163, filed on January 16, 2013, has not yet been consolidated. The defendants in these lawsuits include directors and certain officers of FCX, two FCX
subsidiaries, McMoRan and certain of McMoRan’s directors and officers, and PXP and certain of PXP’s directors. These lawsuits allege, among other things, that the FCX directors breached their fiduciary duties to FCX’s stockholders
because they, among other things, pursued their own interests at the expense of stockholders in approving the FCX/MMR merger and the FCX/PXP merger. These lawsuits further allege that the other defendants aided and abetted that breach of fiduciary
duties. These lawsuits seek, among other things, an injunction barring or rescinding both the FCX/MMR merger and the FCX/PXP merger and requiring submission of both the FCX/MMR merger and the FCX/PXP merger to a vote of FCX stockholders, damages,
and attorneys’ fees and costs. The McMoRan and FCX defendants believe the lawsuits are without merit and intend to defend vigorously against them.

 EXHIBIT B 
 FORM OF GUARANTEE AGREEMENT 
 GUARANTEE AGREEMENT dated as of [—], 20[—] (this “Agreement”), among each of the subsidiaries of FREEPORT-MCMORAN COPPER & GOLD INC., a Delaware corporation (the
“Company”), listed on Schedule I hereto or that become parties hereto as provided in Section 20 of this Agreement (collectively, the “Subsidiary Guarantors”), and JPMORGAN CHASE BANK, N.A., as
Administrative Agent for the Lenders referred to below. 
 Reference is made to the Term Loan Agreement dated as of
[                    ], 2013 (as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Term Loan
Agreement”), among the Company, the other Borrower, if any, party thereto, the Lenders party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent, and Bank of America, N.A., as Syndication Agent. Capitalized terms used and not
otherwise defined herein shall have the meanings set forth in the Term Loan Agreement. For the avoidance of doubt, all references herein (whether in singular or plural, as the context requires) to the Borrower shall give effect to the accession of
PXP as a party to the Term Loan Agreement in the capacity of a borrower pursuant to Section 4.02(c) or 4.04(c) thereof and the cessation of PXP as a party thereto in the capacity of a borrower pursuant to Section 10.02(g) thereof, in each
case to the extent applicable. 
 The Lenders have agreed to make Loans to the Borrowers pursuant to, and upon the terms and
subject to the conditions specified in, the Term Loan Agreement. Each Subsidiary Guarantor is an affiliate of the Borrowers and acknowledges that it has derived and will derive substantial benefit from the making of the Loans by the Lenders. In
order to induce the Lenders to make Loans, and as consideration for Loans previously made, the Subsidiary Guarantors are willing to enter into this Agreement. 
 Accordingly, the parties hereto agree as follows: 
 SECTION 1. Guarantee.
Each Subsidiary Guarantor irrevocably and unconditionally guarantees, jointly with the other Subsidiary Guarantors and severally, as a primary obligor and not merely as a surety, the due and punctual payment and performance of the Obligations. Each
Subsidiary Guarantor agrees that the Obligations may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its Guarantee hereunder notwithstanding any such extension or renewal
of any Obligation. Each Subsidiary Guarantor waives presentment to, demand of payment from and protest to any Borrower or any other Loan Party of any of the Obligations, and also waives notice of acceptance of its guarantee and notice of protest for
nonpayment. 
 SECTION 2. No Limitations. Except for termination of a Subsidiary Guarantor’s obligations hereunder
as expressly provided in Section 10 of this Agreement, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any 







 
reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff,
counterclaim, recoupment or termination whatsoever, by reason of the invalidity, illegality or unenforceability of the Obligations, any impossibility in the performance of the Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Lender, the Administrative Agent or any other Person to whom any of the Obligations are or shall be owed (collectively, the
“Guarantee Beneficiaries”) to assert any claim or demand or to enforce or exercise any right or remedy under the provisions of the Term Loan Agreement, this Agreement, any other Loan Document or otherwise, (b) any extension or
renewal of any of the Obligations, (c) any rescission, waiver, amendment or modification of, or release from any of the terms or provisions of, the Term Loan Agreement, this Agreement, any other Loan Document or any other agreement, including
with respect to any other Subsidiary Guarantor under this Agreement, (d) any default, failure or delay, wilful or otherwise, in the performance of the Obligations (including any failure of the Company or any Subsidiary to comply with
Section 11.01 of the Term Loan Agreement and Section 20 of this Agreement) or (e) any other act, omission or delay to do any other act which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or
otherwise operate as a discharge of any Subsidiary Guarantor as a matter of law or equity (other than the indefeasible payment in full in cash of all the Obligations) or which would impair or eliminate any right of any Subsidiary Guarantor to
subrogation. 
 SECTION 3. Guarantee of Payment. Each Subsidiary Guarantor further agrees that its guarantee hereunder
constitutes a guarantee of payment when due (whether or not any bankruptcy or similar proceeding shall have stayed the accrual or collection of any of the Obligations or operated as a discharge thereof) and not merely of collection, and waives any
right to require that any resort be had by any Guarantee Beneficiary to any balance of any deposit account or credit on the books of any Guarantee Beneficiary in favor of any Borrower, any other Loan Party or any other Person. 

SECTION 4. Defenses of Loan Parties Waived. To the fullest extent permitted by applicable law, each Subsidiary Guarantor waives
any defense based on or arising out of any defense of any Borrower or any other Loan Party or the unenforceability of the Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any Borrower or any other
Loan Party, other than the indefeasible payment in full in cash of all the Obligations. The Guarantee Beneficiaries may, at their election, compromise or adjust any part of the Obligations, make any other accommodation with any Borrower or any other
Loan Party or exercise any other right or remedy available to them against any Borrower or any other Loan Party, without affecting or impairing in any way the liability of any Subsidiary Guarantor hereunder except to the extent all the Obligations
have been fully and indefeasibly paid in cash. To the fullest extent permitted by applicable law, each Subsidiary Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair
or to extinguish any right of reimbursement or subrogation or other right or remedy of such Subsidiary Guarantor against any Borrower or any other Loan Party, as the case may be. 







 SECTION 5. Agreement to Pay; Subordination. In furtherance of the foregoing and not
in limitation of any other right that any Guarantee Beneficiary may have at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of any Borrower or any other Loan Party to pay any Obligation when and as the same shall
become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, each Subsidiary Guarantor hereby promises to and will, upon receipt of written demand by any Agent, forthwith pay, or cause to be paid, to the Administrative
Agent for distribution to the applicable Guarantee Beneficiaries in cash the amount of such unpaid Obligation. Upon payment by any Subsidiary Guarantor of any sums to the Administrative Agent as provided above, all rights of such Subsidiary
Guarantor against any Borrower or any other Loan Party arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all respects be subordinated and junior in right of payment to the prior
indefeasible payment in full in cash of all the Obligations. In addition, any Indebtedness of any Borrower or any Subsidiary Guarantor now or hereafter held by any Subsidiary Guarantor is hereby subordinated in right of payment to the prior
indefeasible payment in full in cash of all the Obligations. If any amount shall erroneously be paid to any Subsidiary Guarantor on account of (a) such subrogation, contribution, reimbursement, indemnity or similar right or (b) any such
Indebtedness of any Borrower or any Subsidiary Guarantor, such amount shall be held in trust for the benefit of the Guarantee Beneficiaries and shall forthwith be paid to the Administrative Agent to be credited against the payment of the
Obligations, whether matured or unmatured, in accordance with the terms of the Term Loan Agreement or any other Loan Document. 

SECTION 6. Information. Each Subsidiary Guarantor assumes all responsibility for being and keeping itself informed of the
Borrowers’ and the other Loan Parties’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Obligations and the nature, scope and extent of the risks that such Subsidiary Guarantor
assumes and incurs hereunder, and agrees that none of the Guarantee Beneficiaries will have any duty to advise such Subsidiary Guarantor of information known to it or any of them regarding such circumstances or risks. 

SECTION 7. Representations and Warranties; Agreements. Each Subsidiary Guarantor represents and warrants as to itself that all
representations and warranties relating to it contained in any Loan Document to which it is a party are true and correct in all material respects. Each Subsidiary Guarantor agrees that the provisions of Section 2.15 of the Term Loan Agreement
shall apply equally to each Subsidiary Guarantor with respect to payments made by it hereunder. 
 SECTION 8. Indemnity and
Subrogation. In addition to all such rights of indemnity and subrogation as the Subsidiary Guarantors may have under applicable law (but subject to Section 5 of this Agreement), the Borrowers agree that in the event a payment shall be made
by any Subsidiary Guarantor under this Agreement, the Borrowers shall indemnify such Subsidiary Guarantor for the full amount of such payment, and the Borrowers shall be subrogated to the rights of the Subsidiary Guarantor to whom such payment shall
have been made to the extent of such payment. 







 SECTION 9. Contribution and Subrogation. Each Subsidiary Guarantor (a
“Contributing Subsidiary Guarantor”) agrees (subject to Section 5 of this Agreement) that, in the event a payment shall be made by any other Subsidiary Guarantor under this Agreement and such other Subsidiary Guarantor (the
“Claiming Subsidiary Guarantor”) shall not have been fully indemnified by the Borrowers as provided in Section 8 of this Agreement, each Contributing Subsidiary Guarantor shall indemnify the Claiming Subsidiary Guarantor in an
amount equal to the amount of such payment multiplied by a fraction of which the numerator shall be the net worth of the Contributing Subsidiary Guarantor on the date hereof (or, in the case of any Subsidiary Guarantor becoming a party hereto
pursuant to Section 20 of this Agreement, the date of the Supplement hereto executed and delivered by such Subsidiary Guarantor) or on the date on which enforcement is being sought, whichever is greater, and the denominator shall be the
aggregate net worth of all the Subsidiary Guarantors on the date hereof (or, in the case of any Subsidiary Guarantor becoming a party hereto pursuant to Section 20 of this Agreement, the date of the Supplement hereto executed and delivered by
such Subsidiary Guarantor) or on the date on which enforcement is being sought, whichever is greater. Any Contributing Subsidiary Guarantor making any payment to a Claiming Subsidiary Guarantor pursuant to this Section shall be subrogated to the
rights of such Claiming Subsidiary Guarantor under Section 8 of this Agreement to the extent of such payment. 
 SECTION
10. Termination. The Guarantees made hereunder (a) shall, subject to clause (b) below, terminate when all the Obligations have been indefeasibly paid in full in cash and the Lenders have no further commitment to lend under the Term
Loan Agreement and (b) shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by any Guarantee Beneficiary or any Subsidiary
Guarantor upon the bankruptcy or reorganization of any Borrower, any Subsidiary Guarantor or otherwise. Notwithstanding the foregoing a Subsidiary Guarantor shall automatically be released from its obligations hereunder (i) upon the
consummation of any transaction permitted by the Term Loan Agreement as a result of which such Subsidiary Guarantor ceases to be a Subsidiary of the Company and (ii) in connection with any Guarantor Termination, on the applicable Guarantor
Termination Date, provided that no release under this clause (ii) shall become effective unless each of the conditions set forth in Section 11.02 of the Term Loan Agreement have been met. 

SECTION 11. Effectiveness; Binding Agreement; Assignments. This Agreement shall become effective as to any Subsidiary Guarantor
when a counterpart hereof executed on behalf of such Subsidiary Guarantor shall have been delivered to the Administrative Agent, and a counterpart hereof shall have been executed on behalf of the Administrative Agent, and thereafter shall be binding
upon the parties hereto and their respective successors and assigns, and shall inure to the benefit of such Subsidiary Guarantor, the Administrative Agent, the other Guarantee Beneficiaries and their respective successors and assigns, except that no
Subsidiary Guarantor shall have the right to assign or otherwise transfer any of its rights or obligations hereunder or any interest herein (except in connection with any transaction permitted by Section 6.03 of the Term Loan Agreement), and
any such attempted assignment or transfer shall be null and void. Whenever in this Agreement any of the parties hereto is referred to, such 







 
reference shall be deemed to include the successors and assigns of such party permitted hereby. This Agreement shall be construed as a separate agreement with respect to each Subsidiary Guarantor
and may be amended, modified, supplemented, waived or released with respect to any Subsidiary Guarantor without the approval of any other Subsidiary Guarantor and without affecting the obligations of any other Subsidiary Guarantor hereunder.

 SECTION 12. Waivers; Amendment. (a) No failure or delay of the Administrative Agent or any Lender in exercising
any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further
exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder or under the Term Loan Agreement or any other Loan Document are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Subsidiary Guarantor therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary
Guarantor to any other or further notice or demand in similar or other circumstances. 
 (b) Neither this Agreement nor any
provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Subsidiary Guarantor or Subsidiary Guarantors with respect to which such waiver, amendment
or modification is to apply, subject to any consent required in accordance with Section 9.02 of the Term Loan Agreement. 

SECTION 13. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

 SECTION 14. Notices. All communications and notices hereunder shall be in writing and given as provided in
Section 9.01 of the Term Loan Agreement. All communications and notices hereunder to each Subsidiary Guarantor shall be given to it in care of the Company as provided in Section 9.01 of the Term Loan Agreement. 

SECTION 15. Survival of Agreement; Severability. (a) All covenants, agreements, representations and warranties made by the
Subsidiary Guarantors herein and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the Administrative Agent and the Lenders and shall
survive the execution and delivery of this Agreement and the making of the Loans, regardless of any investigation made by any of them or on their behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge
of any Default or incorrect representation or warranty at the time any credit is extended under the Term Loan Agreement, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any








 
fee or any other amount payable under this Agreement or any other Loan Document is outstanding and unpaid and as long as the Commitments have not expired or been terminated. 

(b) In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction
shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect
of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 
 SECTION 16.
Counterparts. This Agreement may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 11 of
this Agreement. Delivery of an executed signature page to this Agreement by facsimile or other electronic transmission shall be as effective as delivery of a manually executed counterpart of this Agreement. 

SECTION 17. Rules of Interpretation. The rules of interpretation specified in Sections 1.02, 1.03 and 1.04 of the Term Loan
Agreement shall be applicable to this Agreement. 
 SECTION 18. Jurisdiction; Consent to Service of Process.
(a) This Agreement shall be construed in accordance with and governed by the law of the State of New York. 
 (b) Each
Subsidiary Guarantor hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the
Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby
irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees
that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect
any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against any Subsidiary Guarantor or its properties in the courts of any jurisdiction.

 (c) Each Subsidiary Guarantor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it 







 
may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 14 of this
Agreement. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
 SECTION 19. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 SECTION
20. Additional Subsidiary Guarantors. Upon the execution and delivery by the Administrative Agent and a Subsidiary of an instrument in the form of Annex I hereto, such Subsidiary shall become a Subsidiary Guarantor hereunder with
the same force and effect as if originally named as a Subsidiary Guarantor herein. The execution and delivery of such instrument shall not require the consent of any Subsidiary Guarantor hereunder. The rights and obligations of each Subsidiary
Guarantor hereunder shall remain in full force and effect notwithstanding the addition of any new Subsidiary Guarantor as a party to this Agreement. 
 SECTION 21. Right of Setoff. If an Event of Default shall have occurred and be continuing, the Administrative Agent and the Lenders are hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by such Person to or for the credit or the account of any
Subsidiary Guarantor against any or all the obligations of such Subsidiary Guarantor now or hereafter existing under this Agreement held by such Person, irrespective of whether or not such Person shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of the Administrative Agent and the Lenders under this Section are in addition to other rights and remedies (including other rights of setoff) which such Person may have. 







 IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of the day and
year first above written.

 SCHEDULE I TO THE 
 GUARANTEE AGREEMENT 
 SUBSIDIARY GUARANTORS 







 ANNEX I 
 TO THE SUBSIDIARY 
 GUARANTEE AGREEMENT 

SUPPLEMENT NO. [—] dated as of
[—], 20[—] (this “Supplement”) to the GUARANTEE AGREEMENT dated as of [—], 20[—] (as the same may be amended, supplemented or otherwise modified from time to time, the “Guarantee Agreement”), among each of the Subsidiaries of FREEPORT-MCMORAN COPPER & GOLD
INC., a Delaware corporation (the “Company”), listed on Schedule I thereto (collectively, the “Subsidiary Guarantors”) and JPMORGAN CHASE BANK, N.A., as Administrative Agent for the Lenders referred to below.

 Reference is made to the Term Loan Agreement dated as of
[                    ], 2013 (as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Term Loan
Agreement”), among the Company, the other Borrower, if any, party thereto, the Lenders from time to time party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent, and Bank of America, N.A., as Syndication Agent. 

Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Guarantee Agreement and the Term Loan
Agreement, as applicable. 
 The Subsidiary Guarantors have entered into the Guarantee Agreement in order to induce the Lenders
to make Loans. Section 20 of the Guarantee Agreement provides that additional Subsidiaries may become Subsidiary Guarantors under the Guarantee Agreement by the execution and delivery of an instrument in the form of this Supplement. The
undersigned Subsidiary of the Company (the “New Subsidiary Guarantor”) is executing this Supplement in accordance with the requirements of the Term Loan Agreement to become a Subsidiary Guarantor under the Guarantee Agreement in
order to induce the Lenders to make additional Loans and as consideration for Loans previously made. 
 Accordingly, the
Administrative Agent and the New Subsidiary Guarantor agree as follows:

 The Lenders, Administrative Agent and Syndication Agent 
 c/o JPMorgan Chase Bank, N.A., as Administrative Agent 
 270 Park Avenue 

New York, New York 10017 
 Ladies and Gentlemen:

 We have acted as special New York counsel for Freeport-McMoRan Copper & Gold, Inc., a Delaware corporation (the
“Company”), in connection with the Term Loan Agreement dated as of February [14], 2013 (the “Credit Agreement”) among the Company, the other borrower, if any, party thereto, the lenders party thereto (the
“Lenders”), JPMorgan Chase Bank, N.A., as administrative agent (in such capacity, the “Administrative Agent”), and Bank of America, N.A., as syndication agent (in such capacity, the “Syndication
Agent”). Terms defined in the Credit Agreement and not otherwise defined herein are used herein as therein defined. 

We have reviewed executed copies of: 
 (a) the Credit Agreement; [and] 
 (b) the Co-Borrower Joinder,
dated as of the date hereof, between IMONC LLC, a Delaware limited liability company (“PXP”), and the Administrative Agent[.][; and] 
 [(c) the Guarantee Agreement dated as of the date hereof, among the Subsidiaries listed on the signature pages thereof (collectively, the “Subsidiary Guarantors”) and the Administrative
Agent[.][; and]] 
 [([c][d]) each promissory note (collectively, the “Notes”) dated the date
hereof issued pursuant to Section 2.07(e) of the Credit Agreement.]

the Company[,][and] PXP [and the Subsidiary Guarantors] are sometimes hereinafter referred to as the “Loan Parties” and each a “Loan Party”. 
 We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records and certificates of public officials and officers of the Loan Parties
and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion. In rendering the opinions expressed herein, we have, without independent inquiry or investigation, assumed that
(i) all documents submitted to us as originals are authentic and complete, (ii) all documents submitted to us as copies conform to authentic, complete originals, (iii) all signatures on all documents that we reviewed are genuine,

(vi) all representations made by the Company and the Subsidiaries as to matters of fact in the documents that we reviewed were and are accurate. 
 Based on the foregoing, and subject to the additional assumptions and qualifications set forth below, we are of the opinion that: 
 1. The execution, delivery and performance by each Loan Party of each Credit Document to which it is a party require no action by or in respect of, or filing with, any governmental body, agency or
official under United States federal or New York State law (other than filings pursuant to the Securities Exchange Act of 1934, as amended, and the rules of the New York Stock Exchange) and do not contravene, or constitute a default under, any
provision of (a) applicable United States federal or New York State law or regulation, in each case that in our experience is normally applicable to general business corporations or limited liability companies in relation to transactions of the
type contemplated by the Credit Documents or (b) any agreement or instrument listed in Schedule I hereto (the “Specified Agreements”). 
 2. Each Credit Document[(other than the Notes)] constitutes a valid and binding agreement of each Loan Party party thereto [and each Note constitutes a valid and binding obligation of each Loan Party
issuing such Note], [in each case] enforceable against such Loan Party in accordance with its terms.

 3. None of the Loan Parties is required to register as an “investment company” under the Investment Company Act of 1940, as amended. 

4. The borrowings under the Credit Agreement on the date hereof and the use of proceeds thereof as contemplated by the Credit Agreement
do not violate Regulation U or X of the Board of Governors of the Federal Reserve System. 
 The foregoing opinions are subject
to the following assumptions and qualifications: 
 (a) Our opinions in paragraph 2 above are subject to
applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability. 

(b) We express no opinion as to whether a New York State or United States federal court would enforce the exclusivity of
the jurisdiction of any New York State or United States federal court provided for in any Credit Document. 
 (c)
We express no opinion as to whether a United States federal court would have subject-matter or personal jurisdiction over a controversy arising under the Credit Documents. 

(d) Except as expressly set forth in paragraph 3 above, we express no opinion as to United States federal or any state
securities laws. 
 (e) We express no opinion as to the effect (if any) of any law of any jurisdiction (except
the State of New York) in which any Lender is located which may limit the rate of interest that such Lender may charge or collect. 
 (f) As to various provisions in the Credit Documents that grant the Agents or the Lenders certain rights to make determinations or take actions in their discretion, we assume that such discretion will be
exercised in good faith and in a commercially reasonable manner. 
 (g) We express no opinion as to (i) the
effect of Section 548 of the United States Bankruptcy Code or any similar provision of State law or (ii) any provision of any Credit Document that purports to avoid the effect of fraudulent conveyance, fraudulent transfers or similar
provisions of applicable law by limiting the amount of any Loan Party’s obligations. 
 (h) We express no
opinion on the effectiveness of any service of process made other than in accordance with applicable laws.

opinion may not be relied upon by you for any other purpose or relied upon by any other person without our prior written consent, except that any Person that becomes a Lender under the Credit Agreement in accordance with the provisions of
Section 9.04(b) of the Credit Agreement may rely on this opinion as if it were specifically addressed and delivered to such Person on the date hereof.

 FORM OF OPINION OF JONES, WALKER, WÆCHTER, POITEVANT, CARRÈRE

 The Lenders, Issuing Banks, 
 Administrative Agent and 

Syndication Agent 
 referred to below 

c/o JPMorgan Chase Bank, N.A. 
 270 Park Avenue

 New York, New York 10017 
  

	 	Re:	Freeport-McMoRan Copper & Gold Inc. 


Ladies and Gentlemen: 
 We have
served as counsel to Freeport-McMoRan Copper & Gold Inc., a Delaware corporation (“FCX”), and [IMONC, LLC], a Delaware limited liability company (“IMONC”, and together with FCX and [the subsidiaries of FCX
and IMONC listed on the signature pages of the Guarantee Agreement referred to below that have Delaware as their jurisdiction of formation (the “Delaware Subsidiary Guarantors”)], the “Loan Parties”), in connection
with (i) the preparation, execution and delivery by the Loan Parties [(other than the Delaware Subsidiary Guarantors)] of the Term Credit Agreement dated as of February [14], 2013 (the “Credit Agreement”) among FCX, IMONC, the
issuing banks party thereto (the “Issuing Banks”), JPMorgan Chase Bank, N.A., as administrative agent (in such capacity, the “Administrative Agent”), and Bank of America, N.A., as Syndication Agent (in such capacity
“Syndication Agent”), and (ii) the transactions contemplated thereby. This opinion is delivered pursuant to Section 4.02(b)(ii) of the Credit Agreement. Capitalized terms not otherwise defined herein shall have the
meanings set forth in the Credit Agreement. 
 In connection with this opinion, we have examined executed originals or copies as
executed of the following documents: 
  

	 	(1)	The Credit Agreement; 

  

	 	(2)	The Co-Borrower Joinder dated as of the date hereof, between IMONC and the Administrative Agent; 









	 	(3)	[The Guarantee Agreement dated as of the date hereof, among the subsidiaries of FCX and IMONC listed on the signature pages thereof and the Administrative Agent;] and


  

	 	(4)	Each promissory note dated the date hereof and issued pursuant to Section 2.09(e) of the Credit Agreement. 


The documents listed in items (1) through [(4)] are hereinafter collectively referred to as the “Financing
Documents”. 
 In addition, we have examined the certificate of incorporation and by-laws of FCX, the certificate of
formation and limited liability company agreement of IMONC [and certificates of incorporation or equivalent charter documents and the by-laws or equivalent governing documents of each Delaware Subsidiary Guarantor] (in each case, as amended through
the date hereof). For purposes of the opinions in paragraph 1 below, we have relied exclusively upon certificates issued by the Secretary of State of the State of Delaware and such opinions are not intended to provide any conclusion or assurance
beyond that conveyed by such certificates. 
 We have also examined originals, or copies certified or otherwise identified to
our satisfaction as originals, of such agreements, documents, certificates, consents, resolutions and statements of public officials and corporate officers and representatives and have made such investigations as we have deemed relevant and
necessary in order to render the opinions contained herein. As to any facts material to our opinion, we have relied upon factual representations made in or pursuant to the Financing Documents and the documents referred to therein by the various
parties thereto, and, in addition, we have, when relevant facts were not independently established by us, relied, to the extent we deemed such reliance proper, upon a certificate or certificates or other written or oral advice of an official,
officer, authorized representative or member of the particular governmental authority, corporation, firm or other person or entity concerned. 
 In our examination, we have also assumed, with your permission and without independent verification: 
 (i) the genuineness of all signatures on all documents and instruments examined by us; 
 (ii) the legal capacity of all natural persons who have signed documents and instruments examined by us; 
 (iii) the authenticity and completeness of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as conformed, certified or photostatic
copies and the authenticity of the originals of such copies; 
 (iv) the factual accuracy and completeness of all certificates
submitted to us and of each of the representations and warranties as to matters of fact made in the Financing Documents by each of the parties thereto; 







 (v) that each of the parties to the Financing Documents, other than the Loan Parties, is
duly organized or formed, validly existing and in good standing under the laws of its jurisdiction of organization or formation and has all requisite power and authority to enter into and perform its respective obligations in connection with the
transactions described in the Financing Documents, each of the Financing Documents has been duly authorized, executed and delivered by each of the parties thereto, other than the Loan Parties, and each of the Financing Documents constitutes the
legal, valid and binding obligations of each one of the parties thereto, other than the Loan Parties, under the laws of all jurisdictions applicable thereto; 
 (vi) the accuracy and completeness of all corporate records made available to us by the Loan Parties; 
 (vii) each party to the Financing Documents, other than the Loan Parties, has complied with all legal requirements pertaining to its status, insofar as such status relates to its rights to enforce the
Financing Documents against the Loan Parties and the execution, delivery and performance by each party to the Financing Documents, other than the Loan Parties, do not (a) contravene such party’s articles of association, bylaws or similar
organizational documents, (b) contravene any judicial or administrative judgment, injunction, order or decree that is binding upon such party or its property or assets, (c) violate, or require the consent not obtained under, any
contractual obligation applicable to or binding upon such party or (d) contravene any laws and governmental rules and regulations that may be applicable to such party; 
 (viii) that there are no other agreements or understandings among the parties to the Financing Documents, written or oral, and there is no usage of trade or course of prior dealing among the parties
thereto that would, in any case, define, supplement or qualify the terms of the Financing Documents; 
 (ix) all authorizations,
approvals or consents of, and all filings or registrations with, any governmental or regulatory authority or agency required under the federal laws of the United States of America, the laws of New York or Delaware or any other jurisdiction for the
execution, delivery and performance of the Financing Documents have been obtained or effected and are in full force and effect; provided, however, that the assumption set forth in this subparagraph (ix) is not made in respect of
any such action which is expressly addressed in our opinion in paragraph 4 below; and 
 (x) that the choice of New York law to
govern the Credit Agreement, which is stated therein to be governed thereby, is legal and valid under the laws of other applicable jurisdictions and that insofar as any obligation under any of the Credit Agreement is to be performed in any
jurisdiction outside the United States of America its performance will not be illegal or ineffective by virtue of the law of that jurisdiction. 
 Unless otherwise indicated, whenever our opinion is given with respect to the existence or absence of facts (or legal conclusions which necessarily are based upon the existence or absence of facts) and is
indicated to be based on our knowledge, it is intended to signify that, during the course of our representation of the Loan Parties, in connection with the transactions contemplated by the Financing Documents, no information has come to our
attention which 







 
would give us actual knowledge of the existence or absence of such facts. However, except to the extent expressly set forth herein, we have not undertaken any independent investigation to
determine or verify the existence or absence of such facts, and no inference as to our knowledge of the existence or absence of such facts should be drawn from our representation of the Loan Parties, as stated above. 

This opinion is limited to (i) applicable federal laws and jurisprudence, (ii) the laws set forth in the Delaware Limited
Liability Company Act (the “DLLCA”) and (iii) the General Corporation Law of the State of Delaware (“DGCL”), but, with respect to clauses (ii) and (iii), only to the extent necessary to render the opinions
in paragraphs 1, 3 and 4 below, in each case as of the date hereof, and we express no opinion with respect to the laws of any other state or jurisdiction. 
 Based upon the foregoing and in reliance thereon and upon such other investigations as we have deemed necessary, and subject to the assumptions, limitations, qualifications and exceptions set forth
herein, we are of the opinion that: 
 1. FCX is duly incorporated, validly existing and in good standing under the laws of the
State of Delaware. IMONC[ and each Delaware Subsidiary Guarantor ]is duly formed, validly existing and in good standing under the laws of the State of Delaware. 
 2. Each of the Loan Parties has the corporate or limited liability company, as applicable, power and authority to (a) own its property and assets and to carry on its business as now conducted and as
proposed to be conducted and (b) execute, deliver and perform its obligations under the Financing Documents to which it is a party. 
 3. The Financing Documents have been duly authorized by all necessary corporate or limited liability company, as applicable, action on the part of each Loan Party that is a party thereto and have been
duly executed and delivered by such Person. The execution, delivery and performance by each Loan Party of its agreements and obligations under the Financing Documents to which it is a party will not (i) conflict with or result in a breach or
violation of any of the terms and provisions of the certificate of incorporation, certificate of formation, by-laws, limited liability company agreement or other organizational documents of such Person, each as in effect on the date hereof, or
(ii) violate any law, statute, rule or regulation of the DLLCA or the DGCL, as applicable. 
 4. Except as disclosed in the
Credit Agreement, no consent, approval, authorization, declaration, registration, filing with or order of any Delaware (but only to the extent required by the DGCL or the DLLCA) court or governmental agency or body is or will be required in order
for any of the Loan Parties to (a) execute and deliver the Financing Documents to which it is a party and to perform its respective obligations thereunder, (b) in the case of FCX and IMONC, borrow under the Credit Agreement or [(c) in the
case of the Delaware Subsidiary Guarantors, guarantee the Obligations]. 
 5. Except for Disclosed Matters and other than
Excluded Matters, there are no actions, suits or proceedings at law or in equity or by or before any governmental instrumentality 







 
or other agency or regulatory authority now pending or, to the best of our knowledge, threatened against or affecting FCX or any of the consolidated subsidiaries of FCX or the businesses, assets
or rights of FCX or any of the consolidated subsidiaries of FCX as to which there is (a) a reasonable possibility of an adverse determination and (b) which, if adversely determined, could materially and adversely affect (i) the
businesses, operations or financial condition, of FCX and its consolidated subsidiaries, taken as a whole, or (ii) the ability of any Loan Party to perform its obligations under the Financing Documents to which it is a party. We express no
opinion with respect to actions, suits or proceedings at law or in equity or by or before any governmental instrumentality or other agency or regulatory authority now pending or threatened against or affecting IMONC and any subsidiary of IMONC.

 For purposes of this paragraph 5, 
 “Disclosed Matters” means those matters listed on Exhibit A attached hereto. 
 “Excluded Matters” means any actions, suits or proceedings at law or in equity or by or before any Governmental Authority now pending or threatened against or affecting IMONC and any
subsidiary of IMONC. 
 The foregoing opinions are subject to the following qualifications, exceptions and limitations:

 (A) Without limiting the generality of the foregoing, we express no opinion, in any case, with respect to: 

(i) (a) any laws, rules or regulations relating to (1) pollution or protection of the environment, (2) labor, employee
rights and benefits, ERISA or occupational safety and health, (3) antitrust, (4) securities, (5) tax, (6) federal or state utility or energy regulation, (7) bank regulatory matters, (8) corrupt practices, including,
without, limitation, the Foreign Corrupt Practices Act, (b) any laws, rules, or regulations of any county, parish, municipality or similar subdivision of any state and (c) any other laws to the extent not customarily applicable to
transactions of the type contemplated by the Credit Agreement; 
 (ii) the application of any fraudulent conveyance, fraudulent
transfer, fraudulent obligation or similar law; 
 (iii) the effect of the compliance or noncompliance of the Administrative
Agent or any Lender with any federal, state, local or foreign laws or regulations applicable to the Administrative Agent or any Lender or the Administrative Agent’s or any Lender’s business or the maximum rate of interest chargeable or
collectible by the Administrative Agent or any Lender under applicable statutes and regulations; and 
 (iv) any law,
governmental rule, regulation, or guideline, or any judgment, writ, order, injunction, award, or decree of any court, arbitrator, administrative agency, or other Governmental Authority relating in any way to any environmental or antitrust matter.








 (B) We express no opinion as to the enforceability of the Credit Agreement or any provisions
therein. 
 (C) The opinions set forth herein are further qualified and limited by the following: 

(i) bankruptcy, insolvency, reorganization, moratorium, receivership and other laws now or hereafter in effect relating to or affecting
the enforcement of creditors’ rights generally; 
 (ii) the effect of general principles of equity, including, without
limitation, concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, whether such enforceability is considered in a proceeding in equity or at law, and the
discretion of the court before which any such proceeding may be brought; 
 (iii) public policy considerations or court
decisions that may limit the rights of any party to obtain certain remedies and to indemnification, including indemnification for tortious or criminal acts or violations of law; and 

(iv) the fact that cumulative remedies may not be enforceable to the extent that they purport to or would have the effect of compensating
the party entitled to the benefits thereof in amounts in excess of the actual loss suffered by such party or to the extent that enforcement thereof would violate applicable laws concerning real estate or mixed collateral foreclosures or election of
remedies; and 
 The opinions expressed herein are limited to the specific issues addressed herein and are expressed as
of the date hereof and are not intended to have any prospective effect. We assume no obligation to advise you or any other Person of any changes concerning the above, whether or not deemed material, which may hereafter come or be brought to our
attention, including but not limited to, changes which could result from pending or future legislation, law or jurisprudence. An action, suit or other proceeding is deemed “pending” for purposes of this opinion letter when service of
process relating thereto has been served upon the applicable party. 
 The foregoing expresses our legal opinion as to
the matters set forth above and is based upon our professional knowledge and judgment at this time; it is not, however, to be construed as a guarantee, nor is it a warranty that a court considering such matters would not rule in a manner contrary to
the opinions set forth above. 
 The opinions set forth herein are rendered solely to the Agents, the Issuing Banks and the
Lenders (including their assignees and participants under the Credit Agreement) and are solely for the benefit of such parties in connection with the above transaction and may not be relied upon by them for any other purpose. This letter may not be
delivered to or relied upon by any other person or entity for any purpose without the prior written consent of this firm. This letter is not to be quoted in whole or in part or otherwise referred to in any financial statements or other public
releases, nor is it to be filed with any governmental agency or other person or entity, without the prior written consent of this firm. 







 
	
	Yours very truly,

 EXHIBIT A 
 Disclosed Matters 
 Environmental. FCX incurred environmental capital expenditures
and other environmental costs (including joint venture partners’ share) to comply with applicable environmental laws and regulations that affect its operations totaling $599 million in 2012. 

FCX subsidiaries that operate in the U.S. are subject to various federal, state and local environmental laws and regulations that govern emissions of air
pollutants; discharges of water pollutants; and generation, handling, storage and disposal of hazardous substances, hazardous wastes and other toxic materials. FCX subsidiaries that operate in the U.S. also are subject to potential liabilities
arising under CERCLA or similar state laws that impose responsibility on current and previous owners and operators of a facility for the cleanup of hazardous substances released from the facility into the environment, including damages to natural
resources, irrespective of when the damage to the environment occurred or who caused it. This cleanup liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site
selected by the transporter. This liability often is shared on a joint and several basis meaning that each responsible party is fully responsible for the cleanup, although in many cases some or all of the other historical owners or operators no
longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX’s acquisition of Phelps Dodge Corporation (name changed to Freeport-McMoRan Corporation, referred to as FMC) in 2007, many of the
subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S. FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX
subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and several state agencies that, under CERCLA or similar state laws and regulations, they may be liable
for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address
environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD). As of December 31, 2012, FCX had more than 100 active remediation projects, including NRD
claims, in the U.S. in 28 states. 
 A summary of changes in environmental obligations for the years ended December 31, 2012 (in millions)
follows: 
  

					
	 Balance at beginning of year
	  	$	1,453	  
	 Accretion expense(a)
	  	 	80	  
	 Additions
	  	 	70	  
	 Reductions(b)
	  	 	(182	) 
	 Spending
	  	 	(199	) 
		  	  
	  
	 
	 Balance at end of year
	  	 	1,222	  
	 Less current portion
	  	 	(186	) 
		  	  
	  
	 
	 Long-term portion
	  	$	1,036	  
		  	  
	  
	 









	(a)	Represented accretion of the fair value of environmental obligations assumed in the 2007 acquisition of FMC, which were determined on a discounted cash flow basis.



	(b)	Reductions primarily reflected adjustments for changes in the anticipated scope and timing of environmental remediation projects and the settlement of environmental
matters. 

 Estimated environmental cash payments (on an undiscounted and unescalated basis) total $186 million in 2013, $225
million in 2014, $124 million in 2015, $107 million in 2016, $110 million in 2017 and $1.7 billion thereafter. The amounts and timing of these estimated payments could change as a result of changes in regulatory requirements, changes in scope and
timing of remediation activities, the settlement of environmental matters and as actual spending occurs. 
 FCX was required to record
FMC’s environmental obligations at fair value on the acquisition date in accordance with business combination accounting guidance. Significant adjustments to these obligations may occur in the future. At December 31, 2012, FCX’s
environmental obligations totaled $2.4 billion on an undiscounted and unescalated basis (compared with $1.2 billion recorded on the balance sheet, which included environmental obligations assumed in the FMC acquisition at fair value). FCX estimates
it is reasonably possible that these obligations could range between $2.1 billion and $2.7 billion on an undiscounted and unescalated basis. 

FCX believes that there may be potential claims for recovery from third parties, including the U.S. government and other PRPs. These potential recoveries
are not recognized unless realization is considered probable. 
 At December 31, 2012, the most significant environmental obligations were
associated with the Pinal Creek site in Arizona; the Newtown Creek site in New York City; historical smelter sites principally located in Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania; and uranium mining sites in the western U.S. The
recorded environmental obligations for these sites totaled $1.0 billion at December 31, 2012. A discussion of these sites follows. 

Pinal Creek. The Pinal Creek site was listed under the Arizona Department of Environmental Quality’s (ADEQ) Water Quality Assurance Revolving
Fund program in 1989 for contamination in the shallow alluvial aquifers within the Pinal Creek drainage near Miami, Arizona. Since that time, environmental remediation was performed by members of the Pinal Creek Group (PCG), consisting of FMC Miami,
Inc. (Miami), a wholly owned subsidiary of FMC, and two other companies. In 1998, the District Court approved a Consent Decree between the PCG members and the state of Arizona resolving all matters related to an enforcement action contemplated by
the state of Arizona against the PCG members with respect to groundwater contamination. The Consent Decree committed the PCG members to complete the remediation work outlined in the Consent Decree, and that work continues at this time and is
expected to continue for many years in the future. Miami also was a party to litigation entitled Pinal Creek Group, et al. v. Newmont Mining Corporation, et al., United States District Court, District of Arizona, Case No. CIV 91-1764 PHX DAE
(LOA), filed on May 1, 1991. Pursuant to a settlement 







 
in 2010, Miami paid $40 million to certain members of the PCG to settle the allocation of previously incurred costs, and agreed to take full responsibility for future groundwater remediation at
the Pinal Creek site, with limited exceptions. The settlement did not result in a change to the obligation, which was estimated at fair value when assumed in the FMC acquisition. During 2011, the obligation was increased by $31 million to reflect
changes in remediation capping designs that incorporate best practices for side slope regrading and cap thickness. 
 Newtown Creek. From
the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of FMC, operated a smelter, and from the 1930s until 1984, it operated a refinery on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms
part of the boundary between Brooklyn and Queens in New York City. Heavy industrialization along the banks of the creek and discharges from the City of New York’s sewer system over more than a century resulted in significant environmental
contamination of the waterway. The New York Attorney General previously notified several companies, including PDRC, about possible obligations to clean up contaminated sediments in the creek. In March and April 2010, EPA notified PDRC and five
others that EPA considers them to be PRPs under CERCLA. The notified parties began working with EPA to identify other PRPs, and EPA proposed that the notified parties perform a Remedial Investigation/Feasibility Study (RI/FS) at their expense and
reimburse EPA for its oversight costs. EPA is not expected to propose a remedy until after a RI/FS is completed, which is expected to take several years. On September 29, 2010, EPA designated the creek as a Superfund site. Effective
July 18, 2011, PDRC and five other parties entered an Administrative Order on Consent (AOC) to perform a RI/FS to assess the nature and extent of environmental contamination in the creek and identify potential remedial options. The
parties’ RI/FS work under the AOC and their identification of other PRPs are ongoing. FCX’s financial obligation for this matter was estimated at fair value when it was assumed in the FMC acquisition and is included in FCX’s aggregate
environmental obligations. The actual costs of fulfilling this remedial obligation and the allocation of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remediation remedy ultimately selected by EPA and
related allocation determinations. Depending on the overall cost and the portion allocated to PDRC, that share could be material to FCX. 

Historical Smelter Sites. FMC and its predecessors at various times owned or operated copper and zinc smelters in several states, including
Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania. For some of these smelter sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating and, if appropriate, remediating
environmental conditions associated with the smelters. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate site conditions associated with the smelters. The
historical smelter sites are in various stages of assessment and remediation. The two most significant environmental obligations for historical smelter sites relate to Blackwell, Oklahoma, and Bisbee, Arizona. Adjustments to the environmental
obligations for historical smelter sites, which principally were estimated at fair value when assumed in the FMC acquisition, totaled a reduction of $47 







 
million in 2012, primarily because of changes in estimated timing of obligations, and an increase of $36 million in 2011, primarily at the Blackwell, Oklahoma, site (refer to discussion below).

 Blackwell. From 1918 to 1974, Blackwell Zinc Company, Inc. (BZC), an indirect subsidiary of FCX, owned and operated a zinc smelter in
Blackwell, Oklahoma. In 1974, the smelter was demolished and the property deeded to the Blackwell Industrial Authority. Pursuant to an administrative order with the state of Oklahoma, BZC undertook remedial actions in Blackwell in 1996 and 1997,
including sampling the nearby residential and commercial properties, and removing soils on properties that were found to have metal concentrations above state-established cleanup standards. From 1997 to 2003, BZC investigated the nature and extent
of groundwater contamination potentially attributable to the former smelter and evaluated options for remedying such contamination. In 2003, the state of Oklahoma adopted a cleanup plan requiring the installation of a groundwater extraction and
treatment system and the closure of domestic groundwater wells within the groundwater plume area. BZC completed the construction of a groundwater extraction and treatment system, with system startup and initial discharge of treated water occurring
in October 2010. 
 Between 2007 through 2012, FCX, on behalf of BZC, completed a voluntary soil remediation program by inviting property owners
in and around Blackwell to have soil at their properties sampled for the presence of smelter-related contaminants, and offering to remediate properties whose soils were found to have metal concentrations above state-established cleanup standards. As
part of this program, FCX sampled soils on approximately 90 percent of the residential properties in Blackwell and remediated soils on about 600 properties. All of these soil sampling and remediation activities were coordinated with, and supervised
by, the state of Oklahoma. 
 On May 23, 2012, the Board of Commissioners of Kay County, Oklahoma, filed suit in Oklahoma District Court
against FCX and several affiliates, including BZC, entitled Board of Commissioners of the County of Kay, Oklahoma v. Freeport-McMoRan Copper & Gold Inc., et al., United States District Court, Western District of Oklahoma, Case
No. 5:12-cv-00601-C. On May 25, 2012, the case was removed to the United States District Court for the Western District of Oklahoma, and trial is set for October 2013. The suit alleges BZC permitted large quantities of smelter waste to be
used as road building and fill material throughout Kay County over a period of decades and seeks unspecified financial assistance for removing and covering much of the material, and unspecified damages for the alleged public nuisance created by the
presence of the material. FCX has asserted a counter claim against Kay County for contribution under CERCLA. Separate from the litigation, in fourth-quarter 2012, BZC entered into a Consent Agreement and Final Order with the Oklahoma Department of
Environmental Quality and Kay County to conduct an assessment of smelter material present on Kay County’s roads, bridges and associated rights-of-way. Sampling is expected to be completed in 2013. 

Bisbee. From the 1880s until 1975, FMC and certain predecessor and subsidiary entities operated a copper mine near Bisbee, Arizona. A series of
smelters operated in Bisbee 







 
from approximately 1879 through 1908. In 2000, FMC entered the Bisbee area into the Arizona Voluntary Remediation Program (VRP) administered by ADEQ. In 2008, FMC expanded the VRP project to
include other communities near Bisbee and commenced a voluntary community outreach program inviting property owners to have soils at their properties sampled for the presence of smelter and mine-related metals. For property owners whose soils are
found to have metal concentrations above ADEQ established cleanup standards, FMC has offered to remove the impacted soils and replace them with clean soils. For those property owners who requested sampling, approximately 40 percent require some
level of cleanup. At December 31, 2012, approximately 60 percent of owners who agreed to have soil cleanup on their properties was completed. 
 Uranium Mining Sites. During a period between 1940 and the early 1970s, certain FMC predecessor entities were involved in uranium exploration and mining in the western U.S. Similar exploration and
mining activities by other companies have caused environmental impacts that have warranted remediation, and EPA and local authorities are currently evaluating the need for significant cleanup activities in the region. To date, FMC has undertaken
remediation at a limited number of sites associated with these predecessor entities. An initiative to gather additional information about sites in the region is ongoing, and information gathered under this initiative was submitted to EPA Region 9
during the second and third quarters of 2008 and the fourth quarter of 2009 in response to an information request by EPA regarding uranium mining activities on Navajo Nation properties. FCX utilized the results of FMC’s remediation experience,
in combination with historical and updated information to initially estimate the fair value of uranium-related liabilities assumed in the FMC acquisition. 
 Asset Retirement Obligations (AROs). FCX’s ARO cost estimates are reflected on a third-party cost basis and comply with FCX’s legal obligation to retire tangible, long-lived assets. A
summary of changes in FCX’s AROs for the year ended December 31, 2012 (in millions) follows: 
  

					
	 Balance at beginning of year
	  	$	921	  
	 Liabilities incurred
	  	 	6	  
	 Revisions to cash flow estimates (a)
	  	 	211	  
	 Accretion expense
	  	 	55	  
	 Spending
	  	 	(47	) 
	 Foreign currency translation adjustment
	  	 	—  	  
		  	  
	  
	 
	 Balance at end of year
	  	 	1,146	  
	 Less current portion
	  	 	(55	) 
		  	  
	  
	 
	 Long-term portion
	  	$	1,091	  
		  	  
	  
	 

  

	(a)	Revisions to cash flow estimates were primarily related to updated closure plans that included revised cost estimates and accelerated timing of certain closure
activities. 

 ARO costs may increase or decrease significantly in the future as a result of changes in regulations, changes in
engineering designs and technology, permit modifications or updates, changes in mine plans, inflation or other factors and as actual reclamation spending occurs. ARO activities and expenditures generally are made over an extended period of time
commencing near the end of the mine life; however, certain reclamation activities may be accelerated if legally required or if determined to be economically beneficial. 







 Legal requirements in New Mexico, Arizona and Colorado require financial assurance to be provided for the
estimated costs of reclamation and closure, including groundwater quality protection programs. FCX has satisfied financial assurance requirements by using a variety of mechanisms, such as performance guarantees, financial capability demonstrations,
trust funds, surety bonds, letters of credit and collateral. The applicable regulations specify financial strength tests that are designed to confirm a company’s or guarantor’s financial capability to fund estimated reclamation and closure
costs. The amount of financial assurance FCX is required to provide will vary with changes in laws, regulations and reclamation and closure requirements, and cost estimates. At December 31, 2012, FCX’s financial assurance obligations
associated with these closure and reclamation costs totaled $946 million, of which approximately $582 million was in the form of guarantees issued by FCX and financial capability demonstrations. At December 31, 2012, FCX had trust assets
totaling $161 million, which are legally restricted to fund a portion of its AROs for properties in New Mexico as required by New Mexico regulatory authorities. 
 New Mexico Environmental and Reclamation Programs. FCX’s New Mexico operations are regulated under the New Mexico Water Quality Act and regulations adopted under that act by the Water Quality
Control Commission (WQCC). The New Mexico Environment Department (NMED) has required each of these operations to submit closure plans for NMED’s approval. The closure plans must include measures to assure meeting groundwater quality standards
following the closure of discharging facilities and to abate any groundwater or surface water contamination. In March 2009, the Tyrone operation appealed the WQCC Final Order, dated February 4, 2009, regarding location of the “places of
withdrawal of water,” a legal criterion used to determine where groundwater quality standards must be met at FCX’s New Mexico mining sites. In December 2010, Tyrone entered into a settlement agreement with NMED that calls for a stay of the
appeal while NMED and the WQCC complete several administrative actions, including renewal of Tyrone’s closure permit consistent with the terms of the settlement, review and approval of a groundwater abatement plan and adoption of alternative
abatement standards, and adoption of new groundwater discharge permit rules for copper mines. If the administrative actions are concluded consistent with the terms of the settlement agreement within the period of the stay, then Tyrone will move to
dismiss the appeal. In December 2012, Tyrone and NMED agreed to extend the period to conclude the administrative actions through December 31, 2013. The Court of Appeals also extended the stay for another year. Finalized closure plan
requirements, including those resulting from the actions to be taken under the settlement agreement, could result in increases in the Tyrone, Chino and Cobre closure costs. 
 FCX’s New Mexico operations also are subject to regulation under the 1993 New Mexico Mining Act (the Mining Act) and the related rules that are administered by the Mining and Minerals Division (MMD)
of the New Mexico Energy, Minerals and Natural Resources Department. Under the Mining Act, mines are required to obtain approval of 







 
plans describing the reclamation to be performed following cessation of mining operations. At December 31, 2012, FCX had accrued reclamation and closure costs of $476 million for its New
Mexico operations. As stated above, additional accruals may be required based on the state’s review of FCX’s updated closure plans and any resulting permit conditions, and the amount of those accruals could be material. 

Arizona Environmental and Reclamation Programs. FCX’s Arizona properties are subject to regulatory oversight in several areas. ADEQ has
adopted regulations for its aquifer protection permit (APP) program that require permits for, among other things, certain facilities, activities and structures used for mining, concentrating and smelting and require compliance with aquifer water
quality standards at an applicable point of compliance well or location. The APP program also may require mitigation and discharge reduction or elimination of some discharges. 
 An application for an APP requires a description of a closure strategy that will meet applicable groundwater protection requirements following cessation of operations and an estimate of the cost to
implement the closure strategy. An APP may specify closure requirements, which may include post-closure monitoring and maintenance. A more detailed closure plan must be submitted within 90 days after a permitted entity notifies ADEQ of its intent to
cease operations. A permit applicant must demonstrate its financial ability to meet the closure costs estimated in the APP. 
 Portions of
Arizona mining facilities that operated after January 1, 1986, also are subject to the Arizona Mined Land Reclamation Act (AMLRA). AMLRA requires reclamation to achieve stability and safety consistent with post-mining land use objectives
specified in a reclamation plan. Reclamation plans must be approved by the State Mine Inspector and must include an estimate of the cost to perform the reclamation measures specified in the plan. FCX will continue to evaluate options for future
reclamation and closure activities at its operating and non-operating sites, which are likely to result in adjustments to FCX’s ARO liabilities. At December 31, 2012, FCX had accrued reclamation and closure costs of $240 million for its
Arizona operations. 
 Colorado Reclamation Programs. FCX’s Colorado operations are regulated by the Colorado Mined Land Reclamation
Act (Reclamation Act) and regulations promulgated thereunder. Under the Reclamation Act, mines are required to obtain approval of reclamation plans describing the reclamation of lands affected by mining operations to be performed during mining or
upon cessation of mining operations. As of December 31, 2012, FCX had accrued reclamation and closure costs of $47 million for its Colorado operations. 
 Chilean Reclamation and Closure Programs. In July 2011, the Chilean senate passed legislation regulating mine closure, which establishes new requirements for closure plans and became effective in
November 2012. FCX’s Chilean operations will be required to update closure plans and provide financial assurance for these obligations. FCX cannot predict at this time the cost of these closure plans or the levels or forms of financial
assurance that may be required. Revised closure plans for the Chilean mine sites are due in November 2014. At December 31, 2012, FCX had accrued reclamation and closure costs of $54 million for its Chilean operations. 







 Peruvian Reclamation and Closure Programs. Cerro Verde is subject to regulation under the Mine
Closure Law administered by the Peruvian Ministry of Energy and Mines. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and
post-closure plans and financial assurance. The updated closure plan for the Cerro Verde mine expansion must be submitted to the Peruvian regulatory authorities in December 2014. At December 31, 2012, Cerro Verde had accrued reclamation and
closure costs of $89 million. 
 PT Freeport Indonesia Reclamation and Closure Programs. The ultimate amount of reclamation and closure
costs to be incurred at PT Freeport Indonesia’s operations will be determined based on applicable laws and regulations and PT Freeport Indonesia’s assessment of appropriate remedial activities in the circumstances, after consultation with
governmental authorities, affected local residents and other affected parties and cannot currently be projected with precision. Estimates of the ultimate reclamation and closure costs PT Freeport Indonesia will incur in the future involve complex
issues requiring integrated assessments over a period of many years and are subject to revision over time as more complete studies are performed. Some reclamation costs will be incurred during mining activities, while most closure costs and the
remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue for approximately 30 years. At December 31, 2012, PT Freeport Indonesia had accrued reclamation and closure costs of $195
million and a long-term receivable for Rio Tinto’s share of the obligation of $18 million (included in long-term receivables). 
 In 1996,
PT Freeport Indonesia began contributing to a cash fund ($16 million balance at December 31, 2012) designed to accumulate at least $100 million (including interest) by the end of its Indonesia mining activities. PT Freeport Indonesia plans to
use this fund, including accrued interest, to pay mine closure and reclamation costs. Any costs in excess of the $100 million fund would be funded by operational cash flow or other sources. 
 In December 2010, the President of Indonesia issued a regulation regarding mine reclamation and closure, which requires a company to provide a mine closure guarantee in the form of a time deposit placed
in a state-owned bank in Indonesia. In accordance with its Contract of Work, PT Freeport Indonesia is working with the Department of Energy and Mineral Resources to review these requirements, including discussion of other options for the mine
closure guarantee. In December 2009, PT Freeport Indonesia submitted its revised mine closure plan to the Department of Energy and Mineral Resources for review and has addressed comments received during the course of this review process. 








 Litigation. 
 Asbestos Claims. Since approximately 1990, FMC and various subsidiaries have been named as defendants in a large number of lawsuits that claim personal injury either from exposure to asbestos
allegedly contained in electrical wire products produced or marketed many years ago or from asbestos contained in buildings and facilities located at properties owned or operated by FMC affiliates, or from alleged asbestos in talc products. Many of
these suits involve a large number of codefendants. Based on litigation results to date and facts currently known, FCX believes there is a reasonable possibility that losses may have been incurred related to these matters; however, FCX also believes
that the amounts of any such losses, individually or in the aggregate, are not material to its consolidated financial statements. There can be no assurance, however, that future developments will not alter this conclusion. 

Yonkers Site. From 1932 until 1984, FMC owned and operated a cable manufacturing facility on the Hudson River in Yonkers, New York. FMC sold that
operation in 1984, and it was subsequently sold to BICC Cables Corporation (BICC). BICC closed the facility in 1996. In 2005, Blackacre Partners OPS, LLC (Blackacre) began environmental cleanup work at the site using funding provided by FMC and
BICC. One Point Street, Inc. (OPS), a real estate developer, has current title to the site. 
 On September 9, 2011, OPS filed a complaint
in the United States District Court for the Southern District of New York, which it amended on March 1, 2012. The amended complaint alleged that FMC, BICC and Blackacre failed to timely and diligently complete remediation of the site in breach
of alleged obligations under CERCLA and New York Environmental Conservation Law, and under the contractual agreements among the parties. In fourth-quarter 2012, this matter was settled, and OPS will be completing the limited remaining cleanup work
at the site using funds provided by FMC and BICC. 
 Columbian Chemicals Company (Columbian) Claims. Columbian, formerly a subsidiary of
FMC, has notified FCX of various indemnification claims arising out of the 2005 agreement pursuant to which Columbian was sold. The principal outstanding claims relate to (1) multiple mass tort suits pending against Columbian in West Virginia
state court for alleged personal injury and property damage resulting from exposure to carbon black (the Carbon Black claims) and (2) an investigation being conducted by EPA of potential Clean Air Act violations during the period Columbian was
owned by FMC (the Clean Air Act matter). In April 2012, Columbian filed suit in New York state court (Columbian Chemicals Company and Columbian Chemicals Acquisition LLC v. Freeport-McMoRan Corporation f/k/a Phelps Dodge Corporation, County
of New York, Supreme Court of the State of New York, Index No. 600999/2010), that alleged, among other things, that the Carbon Black claims are the responsibility of FMC, and are not subject to the aggregate cap under the 2005 agreement pursuant to
which Columbian was sold. In July 2012, FCX and Columbian reached a settlement pursuant to which the litigation was dismissed with prejudice and all outstanding disputes regarding the extent of FCX’s indemnity obligations to Columbian were
fully resolved. Under the terms of the settlement, FCX’s remaining possible exposure is to indemnify Columbian for incurred losses related only to the Carbon Black claims and the Clean Air Act matter. The cap, net








 
of amounts reserved and paid, totaled $122 million at December 31, 2012. FMC cannot estimate Columbian’s exposure, if any, for the Carbon Black claims or the Clean Air Act matter.

 Shareholder Litigation. Thirteen derivative actions challenging the PXP merger and/or the MMR merger were filed on behalf of FCX by
purported FCX stockholders. Ten were filed in the Court of Chancery of the State of Delaware and three were filed in the Superior Court of the State of Arizona, County of Maricopa. On January 25, 2013, the Delaware Court of Chancery
consolidated the Delaware actions into a single action, In Re Freeport-McMoRan Copper & Gold Inc. Derivative Litigation, No. 8145-VCN. On January 17, 2013, the Arizona Superior Court consolidated two of the Arizona actions
into In Re Freeport-McMoRan Derivative Litigation, No. CV2012-018351. A third Arizona complaint, Harris v. Adkerson et al., No. CV2013-004163, filed on January 16, 2013, has not yet been consolidated. The actions name some or all of the
following as defendants: the directors and certain officers of FCX, two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions allege, among other things, that the FCX directors breached
their fiduciary duties to FCX stockholders because they, among other things, pursued their own interests at the expense of stockholders in approving the PXP and MMR mergers. The complaints also allege that some or all of the following parties aided
and abetted the wrongful acts allegedly committed by the directors and certain officers of FCX: two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions seek as relief, among other
things, an injunction barring or rescinding both the PXP merger and the MMR merger and requiring submission of the proposed PXP merger and MMR merger to a vote of FCX stockholders, damages, and attorneys’ fees and costs. 

Three putative class actions challenging the PXP merger were filed on behalf of PXP stockholders in the Court of Chancery of the State of Delaware. On
January 15, 2013, the Court of Chancery consolidated the actions into a single action, In Re Plains Exploration & Production Company Stockholder Litigation, No. 8090-VCN. The action names as defendants PXP, the directors of
PXP, FCX, and an FCX subsidiary. The action alleges that PXP’s directors breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with
respect to the merger, and that FCX and an FCX subsidiary aided and abetted the breach of fiduciary duties by PXP’s directors. The action seeks as relief an injunction barring or rescinding the PXP merger, damages, and attorneys’ fees and
costs. 
 In addition, ten putative class actions challenging the MMR merger were filed on behalf of MMR stockholders. Nine were filed in the
Court of Chancery of the State of Delaware. On January 25, 2012, the Court of Chancery consolidated the actions into a single action, In Re McMoRan Exploration Co. Stockholder Litigation, No. 8132-VCN. One action was also filed in
the Civil District Court for the Parish of Orleans of the State of Louisiana: Langley v. Moffett et al., No. 2012-11904, filed December 19, 2012. Each of the actions names some or all of the following as defendants, in addition to
MMR and its directors: FCX, subsidiaries of FCX, and PXP. The actions allege that MMR’s directors 







 
breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with respect to the merger,
and that PXP, FCX, or both, aided and abetted the breach of fiduciary duty by MMR’s directors. The Delaware action also asserts claims derivatively on behalf of MMR. The actions seek, among other things, injunctive relief barring or rescinding
the MMR merger, damages, and attorneys’ fees and costs. 
 FCX intends to vigorously defend itself in these matters. 

Tax Matters. Cerro Verde Tax Proceedings. SUNAT, the Peruvian national tax authority, has assessed mining royalties on materials processed
by the Cerro Verde concentrator that commenced operations in late 2006. These assessments cover the period October 2006 to December 2007 and the years 2008 and 2009. SUNAT has issued rulings denying Cerro Verde’s protest of the assessments.
Cerro Verde has appealed these decisions and currently has three cases pending before the Peruvian Tax Court. Cerro Verde is challenging these royalties because it believes its stability agreement provides an exemption for all minerals extracted
from its mining concession, irrespective of the method used for processing those minerals. Although FCX believes its interpretation of the stability agreement is correct, if Cerro Verde is ultimately found responsible for these assessments, it will
also be liable for interest, which accrues at rates that range from approximately 7 to 18 percent based on the year accrued and the currency in which the amounts would be payable. At December 31, 2012, the aggregate amount of the assessments,
including interest and penalties, totaled $218 million. SUNAT may continue to assess mining royalties annually until this matter is resolved by the Peruvian Tax Tribunal. 
 Cerro Verde is also challenging various income and value-added tax assessments from SUNAT covering the years 2002 through 2008 and has cases pending before the Peruvian Tax Court. At December 31,
2012, the approximate amount of these assessments, including interest and penalties, totaled $180 million. 
 Indonesia Tax Matters. The
Indonesian tax authorities issued assessments for various audit exceptions on PT Freeport Indonesia’s tax returns as follows (in millions):

 PT Freeport Indonesia has filed objections to the assessments because it believes it has properly paid its taxes. During
first-quarter 2012, PT Freeport Indonesia’s objections to the assessments related to 2005 were substantially all rejected by the Indonesian tax authorities and, in May 2012, appeals were filed with the Indonesian Tax Court. As of








 
December 31, 2012, PT Freeport Indonesia has paid $182 million (of which $148 million is included in long-term receivables) for the disputed tax assessments related to 2005, 2006 and 2007.
PT Freeport Indonesia is working with the Indonesian tax authorities to resolve these matters and expects to receive additional assessments from the Indonesian tax authorities for their audit of its 2008 tax return. 

In December 2009, PT Freeport Indonesia was notified by the Large Taxpayer’s Office of the Government of Indonesia of its view that PT Freeport
Indonesia is obligated to pay value added taxes on certain goods imported after the year 2000. The amount of such taxes and related penalties under this view would be significant. PT Freeport Indonesia believes that, pursuant to the terms of its
Contract of Work, it is only required to pay value added taxes on these types of goods imported after December 30, 2009. PT Freeport Indonesia has not received a formal assessment and is working with the applicable government authorities to
resolve this matter. 
 Letters of Credit, Bank Guarantees and Surety Bonds. Letters of credit and bank guarantees totaled $98 million at
December 31, 2012, primarily for reclamation and environmental obligations, workers’ compensation insurance programs, tax and customs obligations, and other commercial obligations. In addition, FCX had surety bonds totaling $159 million at
December 31, 2012, associated with reclamation and closure ($137 million – see discussion above), self-insurance bonds primarily for workers’ compensation ($18 million) and other bonds ($4 million). 

Insurance. FCX purchases a variety of insurance products to mitigate potential losses. The various insurance products typically have specified
deductible amounts or self-insured retentions and policy limits. FCX generally is self-insured for U.S. workers’ compensation, but purchases excess insurance up to statutory limits. An actuarial analysis is performed twice a year for various
FCX casualty programs, including workers’ compensation, to estimate required insurance reserves. Insurance reserves totaled $52 million at December 31, 2012, which consisted of a current portion of $8 million (included in accounts payable
and accrued liabilities) and a long-term portion of $44 million (included in other liabilities). 
 FCX maintains property damage and business
interruption insurance related to its operations. FCX and its insurers entered into an insurance settlement agreement in December 2012. The insurers agreed to pay an aggregate of $63 million, including $4 million for PT Freeport Indonesia’s
joint venture partner’s interest, for the settlement of the insurance claim for business interruption and property damage relating to the 2011 incidents affecting PT Freeport Indonesia’s concentrate pipelines. As a result of the
settlement, FCX recorded a gain of $59 million ($31 million to net income attributable to FCX common stockholders).

 Ladies and Gentlemen:

 We have acted as special New York counsel for Freeport-McMoRan Copper & Gold, Inc., a Delaware corporation (the
“Company”), in connection with the Term Loan Agreement dated as of February [14], 2013 (the “Credit Agreement”) among the Company, the other borrower, if any, party thereto, the lenders party thereto (the
“Lenders”), JPMorgan Chase Bank, N.A., as administrative agent (in such capacity, the “Administrative Agent”), and Bank of America, N.A., as syndication agent (in such capacity, the “Syndication
Agent”). Terms defined in the Credit Agreement and not otherwise defined herein are used herein as therein defined. 

We have reviewed [an executed copy of the Credit Agreement][executed copies of: 

(a) the Credit Agreement; [and] 
 [(b) the Guarantee Agreement dated as of the date hereof, among the Subsidiaries listed on the signature pages thereof (collectively, the “Subsidiary Guarantors”) and the Administrative
Agent[.][; and]] 
 [([b][c]) each promissory note (collectively, the “Notes”) dated the date hereof issued
pursuant to Section 2.07(e) of the Credit Agreement.]]

constitute a default under, any provision of (a) applicable United States federal or New York State law or regulation, in each case that in our experience is normally applicable to general business corporations [or limited liability companies]

2. [The Credit Agreement][Each Credit Document] [(other than the Notes)] constitutes a valid and binding agreement of [the Company][each
Loan Party party thereto] [and each Note constitutes a valid and binding obligation of the Company], [in each case] enforceable against [the Company][such Loan Party] in accordance with its terms.

	 	Re:	Freeport-McMoRan Copper & Gold Inc. 


Ladies and Gentlemen: 
 We have
served as counsel to Freeport-McMoRan Copper & Gold Inc., a Delaware corporation (“FCX”, [ and together with the subsidiaries of FCX listed on the signature pages of the Guarantee Agreement referred to below that have
Delaware as their jurisdiction of formation (the “Delaware Subsidiary Guarantors”)], the “Loan Parties”), in connection with (i) the preparation, execution and delivery by the Loan Parties [(other than the
Delaware Subsidiary Guarantors)] of the Term Credit Agreement dated as of February [14], 2013 (the “Credit Agreement”) among FCX, the issuing banks party thereto (the “Issuing Banks”), JPMorgan Chase Bank, N.A., as
administrative agent (in such capacity, the “Administrative Agent”), and Bank of America, N.A., as Syndication Agent (in such capacity “Syndication Agent”), and (ii) the transactions contemplated thereby. This
opinion is delivered pursuant to Section 4.03(b)(ii) of the Credit Agreement. Capitalized terms not otherwise defined herein shall have the meanings set forth in the Credit Agreement. 

In connection with this opinion, we have examined executed originals or copies as executed of the following documents: 

 

	 	(1)	The Credit Agreement; 

  

	 	(2)	[The Guarantee Agreement dated as of the date hereof, among the subsidiaries of FCX listed on the signature pages thereof and the Administrative Agent;] and


  

	 	(3)	Each promissory note dated the date hereof and issued pursuant to Section 2.09(e) of the Credit Agreement. 








 The documents listed in items (1) through [(4)] are hereinafter collectively referred
to as the “Financing Documents”. 
 In addition, we have examined the certificate of incorporation and by-laws
of FCX, [and certificates of incorporation or equivalent charter documents and the by-laws or equivalent governing documents of each Delaware Subsidiary Guarantor] (in each case, as amended through the date hereof). For purposes of the opinions in
paragraph 1 below, we have relied exclusively upon certificates issued by the Secretary of State of the State of Delaware and such opinions are not intended to provide any conclusion or assurance beyond that conveyed by such certificates.

 We have also examined originals, or copies certified or otherwise identified to our satisfaction as originals, of such
agreements, documents, certificates, consents, resolutions and statements of public officials and corporate officers and representatives and have made such investigations as we have deemed relevant and necessary in order to render the opinions
contained herein. As to any facts material to our opinion, we have relied upon factual representations made in or pursuant to the Financing Documents and the documents referred to therein by the various parties thereto, and, in addition, we have,
when relevant facts were not independently established by us, relied, to the extent we deemed such reliance proper, upon a certificate or certificates or other written or oral advice of an official, officer, authorized representative or member of
the particular governmental authority, corporation, firm or other person or entity concerned. 
 In our examination, we have
also assumed, with your permission and without independent verification: 
 (i) the genuineness of all signatures on all
documents and instruments examined by us; 
 (ii) the legal capacity of all natural persons who have signed documents and
instruments examined by us; 
 (iii) the authenticity and completeness of all documents submitted to us as originals and the
conformity to original documents of all documents submitted to us as conformed, certified or photostatic copies and the authenticity of the originals of such copies; 
 (iv) the factual accuracy and completeness of all certificates submitted to us and of each of the representations and warranties as to matters of fact made in the Financing Documents by each of the
parties thereto; 
 (v) that each of the parties to the Financing Documents, other than the Loan Parties, is duly organized or
formed, validly existing and in good standing under the laws of its jurisdiction of organization or formation and has all requisite power and authority to enter into and perform its respective obligations in connection with the transactions
described in the 

  
 2 








 
Financing Documents, each of the Financing Documents has been duly authorized, executed and delivered by each of the parties thereto, other than the Loan Parties, and each of the Financing
Documents constitutes the legal, valid and binding obligations of each one of the parties thereto, other than the Loan Parties, under the laws of all jurisdictions applicable thereto; 

(vi) the accuracy and completeness of all corporate records made available to us by the Loan Parties; 

(vii) each party to the Financing Documents, other than the Loan Parties, has complied with all legal requirements pertaining to its
status, insofar as such status relates to its rights to enforce the Financing Documents against the Loan Parties and the execution, delivery and performance by each party to the Financing Documents, other than the Loan Parties, do not
(a) contravene such party’s articles of association, bylaws or similar organizational documents, (b) contravene any judicial or administrative judgment, injunction, order or decree that is binding upon such party or its property or
assets, (c) violate, or require the consent not obtained under, any contractual obligation applicable to or binding upon such party or (d) contravene any laws and governmental rules and regulations that may be applicable to such party;

 (viii) that there are no other agreements or understandings among the parties to the Financing Documents, written or oral,
and there is no usage of trade or course of prior dealing among the parties thereto that would, in any case, define, supplement or qualify the terms of the Financing Documents; 

(ix) all authorizations, approvals or consents of, and all filings or registrations with, any governmental or regulatory authority or
agency required under the federal laws of the United States of America, the laws of New York or Delaware or any other jurisdiction for the execution, delivery and performance of the Financing Documents have been obtained or effected and are in full
force and effect; provided, however, that the assumption set forth in this subparagraph (ix) is not made in respect of any such action which is expressly addressed in our opinion in paragraph 4 below; and 

(x) that the choice of New York law to govern the Credit Agreement, which is stated therein to be governed thereby, is legal and valid
under the laws of other applicable jurisdictions and that insofar as any obligation under any of the Credit Agreement is to be performed in any jurisdiction outside the United States of America its performance will not be illegal or ineffective by
virtue of the law of that jurisdiction. 
 Unless otherwise indicated, whenever our opinion is given with respect to the
existence or absence of facts (or legal conclusions which necessarily are based upon the existence or absence of facts) and is indicated to be based on our knowledge, it is intended to signify that, during the course of our representation of the
Loan Parties, in connection with the transactions contemplated by the Financing Documents, no information has come to our attention which would give us actual knowledge of the existence or absence of such facts. However, except to the extent
expressly set forth herein, we have not undertaken any independent investigation to determine or verify the existence or absence of such facts, and no inference as to our knowledge of the existence or absence of such facts should be drawn from our
representation of the Loan Parties, as stated above.

 This opinion is limited to (i) applicable federal laws and jurisprudence, (ii) the
laws set forth in the Delaware Limited Liability Company Act (the “DLLCA”) and (iii) the General Corporation Law of the State of Delaware (“DGCL”), but, with respect to clauses (ii) and (iii), only to the
extent necessary to render the opinions in paragraphs 1, 3 and 4 below, in each case as of the date hereof, and we express no opinion with respect to the laws of any other state or jurisdiction. 

Based upon the foregoing and in reliance thereon and upon such other investigations as we have deemed necessary, and subject to the
assumptions, limitations, qualifications and exceptions set forth herein, we are of the opinion that: 
 1. FCX is duly
incorporated, validly existing and in good standing under the laws of the State of Delaware. [Each Delaware Subsidiary Guarantor is duly formed, validly existing and in good standing under the laws of the State of Delaware.] 

2. Each of the Loan Parties has the corporate or limited liability company, as applicable, power and authority to (a) own its
property and assets and to carry on its business as now conducted and as proposed to be conducted and (b) execute, deliver and perform its obligations under the Financing Documents to which it is a party. 

3. The Financing Documents have been duly authorized by all necessary corporate or limited liability company, as applicable, action on
the part of each Loan Party that is a party thereto and have been duly executed and delivered by such Person. The execution, delivery and performance by each Loan Party of its agreements and obligations under the Financing Documents to which it is a
party will not (i) conflict with or result in a breach or violation of any of the terms and provisions of the certificate of incorporation, certificate of formation, by-laws, limited liability company agreement or other organizational documents
of such Person, each as in effect on the date hereof, or (ii) violate any law, statute, rule or regulation of the DLLCA or the DGCL, as applicable. 
 4. Except as disclosed in the Credit Agreement, no consent, approval, authorization, declaration, registration, filing with or order of any Delaware (but only to the extent required by the DGCL or the
DLLCA) court or governmental agency or body is or will be required in order for any of the Loan Parties to (a) execute and deliver the Financing Documents to which it is a party and to perform its respective obligations thereunder, (b) in
the case of FCX, borrow under the Credit Agreement or [(c) in the case of the Delaware Subsidiary Guarantors, guarantee the Obligations]. 
 5. Except for Disclosed Matters, there are no actions, suits or proceedings at law or in equity or by or before any governmental instrumentality or other agency or regulatory authority now pending or, to
the best of our knowledge, threatened against or affecting FCX or any of the consolidated subsidiaries of FCX or the businesses, assets or rights of FCX or any of the consolidated subsidiaries of FCX as to which there is (a) a reasonable
possibility of an 

  
 4 








 
adverse determination and (b) which, if adversely determined, could materially and adversely affect (i) the businesses, operations or financial condition, of FCX and its consolidated
subsidiaries, taken as a whole, or (ii) the ability of any Loan Party to perform its obligations under the Financing Documents to which it is a party. 
 For purposes of this paragraph 5, 
 “Disclosed Matters” means
those matters listed on Exhibit A attached hereto. 
 The foregoing opinions are subject to the following qualifications,
exceptions and limitations: 
  

	 	(A)	Without limiting the generality of the foregoing, we express no opinion, in any case, with respect to: 


(i) (a) any laws, rules or regulations relating to (1) pollution or protection of the environment, (2) labor, employee
rights and benefits, ERISA or occupational safety and health, (3) antitrust, (4) securities, (5) tax, (6) federal or state utility or energy regulation, (7) bank regulatory matters, (8) corrupt practices, including,
without, limitation, the Foreign Corrupt Practices Act, (b) any laws, rules, or regulations of any county, parish, municipality or similar subdivision of any state and (c) any other laws to the extent not customarily applicable to
transactions of the type contemplated by the Credit Agreement; 
 (ii) the application of any fraudulent conveyance, fraudulent
transfer, fraudulent obligation or similar law; 
 (iii) the effect of the compliance or noncompliance of the Administrative
Agent or any Lender with any federal, state, local or foreign laws or regulations applicable to the Administrative Agent or any Lender or the Administrative Agent’s or any Lender’s business or the maximum rate of interest chargeable or
collectible by the Administrative Agent or any Lender under applicable statutes and regulations; and 
 (iv) any law,
governmental rule, regulation, or guideline, or any judgment, writ, order, injunction, award, or decree of any court, arbitrator, administrative agency, or other Governmental Authority relating in any way to any environmental or antitrust matter.

 (B) We express no opinion as to the enforceability of the Credit Agreement or any provisions therein. 

(C) The opinions set forth herein are further qualified and limited by the following: 

(i) bankruptcy, insolvency, reorganization, moratorium, receivership and other laws now or hereafter in effect relating to or affecting
the enforcement of creditors’ rights generally; 

  
 5 








 (ii) the effect of general principles of equity, including, without limitation, concepts of
materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, whether such enforceability is considered in a proceeding in equity or at law, and the discretion of the court
before which any such proceeding may be brought; 
 (iii) public policy considerations or court decisions that may limit the
rights of any party to obtain certain remedies and to indemnification, including indemnification for tortious or criminal acts or violations of law; and 
 (iv) the fact that cumulative remedies may not be enforceable to the extent that they purport to or would have the effect of compensating the party entitled to the benefits thereof in amounts in excess of
the actual loss suffered by such party or to the extent that enforcement thereof would violate applicable laws concerning real estate or mixed collateral foreclosures or election of remedies; and 

The opinions expressed herein are limited to the specific issues addressed herein and are expressed as of the date hereof and are
not intended to have any prospective effect. We assume no obligation to advise you or any other Person of any changes concerning the above, whether or not deemed material, which may hereafter come or be brought to our attention, including but not
limited to, changes which could result from pending or future legislation, law or jurisprudence. An action, suit or other proceeding is deemed “pending” for purposes of this opinion letter when service of process relating thereto has been
served upon the applicable party. 
 The foregoing expresses our legal opinion as to the matters set forth above and is
based upon our professional knowledge and judgment at this time; it is not, however, to be construed as a guarantee, nor is it a warranty that a court considering such matters would not rule in a manner contrary to the opinions set forth above.

 The opinions set forth herein are rendered solely to the Agents, the Issuing Banks and the Lenders (including their assignees
and participants under the Credit Agreement) and are solely for the benefit of such parties in connection with the above transaction and may not be relied upon by them for any other purpose. This letter may not be delivered to or relied upon by any
other person or entity for any purpose without the prior written consent of this firm. This letter is not to be quoted in whole or in part or otherwise referred to in any financial statements or other public releases, nor is it to be filed with any

 EXHIBIT A 
 Disclosed Matters 
 Environmental. FCX incurred environmental capital expenditures
and other environmental costs (including joint venture partners’ share) to comply with applicable environmental laws and regulations that affect its operations totaling $599 million in 2012. 

FCX subsidiaries that operate in the U.S. are subject to various federal, state and local environmental laws and regulations that govern emissions of air
pollutants; discharges of water pollutants; and generation, handling, storage and disposal of hazardous substances, hazardous wastes and other toxic materials. FCX subsidiaries that operate in the U.S. also are subject to potential liabilities
arising under CERCLA or similar state laws that impose responsibility on current and previous owners and operators of a facility for the cleanup of hazardous substances released from the facility into the environment, including damages to natural
resources, irrespective of when the damage to the environment occurred or who caused it. This cleanup liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site
selected by the transporter. This liability often is shared on a joint and several basis meaning that each responsible party is fully responsible for the cleanup, although in many cases some or all of the other historical owners or operators no
longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX’s acquisition of Phelps Dodge Corporation (name changed to Freeport-McMoRan Corporation, referred to as FMC) in 2007, many of the
subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S. FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX
subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and several state agencies that, under CERCLA or similar state laws and regulations, they may be liable
for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address
environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD). As of December 31, 2012, FCX had more than 100 active remediation projects, including NRD
claims, in the U.S. in 28 states. 
 A summary of changes in environmental obligations for the years ended December 31, 2012 (in millions)
follows: 
  

					
	 Balance at beginning of year
	  	$	1,453	  
	 Accretion expense(a)
	  	 	80	  
	 Additions
	  	 	70	  
	 Reductions(b)
	  	 	(182	) 
	 Spending
	  	 	(199	) 
		  	  
	  
	 
	 Balance at end of year
	  	 	1,222	  
	 Less current portion
	  	 	(186	) 
		  	  
	  
	 
	 Long-term portion
	  	$	1,036	  
		  	  
	  
	 









	(a)	Represented accretion of the fair value of environmental obligations assumed in the 2007 acquisition of FMC, which were determined on a discounted cash flow basis.



	(b)	Reductions primarily reflected adjustments for changes in the anticipated scope and timing of environmental remediation projects and the settlement of environmental
matters. 

 Estimated environmental cash payments (on an undiscounted and unescalated basis) total $186 million in 2013, $225
million in 2014, $124 million in 2015, $107 million in 2016, $110 million in 2017 and $1.7 billion thereafter. The amounts and timing of these estimated payments could change as a result of changes in regulatory requirements, changes in scope and
timing of remediation activities, the settlement of environmental matters and as actual spending occurs. 
 FCX was required to record
FMC’s environmental obligations at fair value on the acquisition date in accordance with business combination accounting guidance. Significant adjustments to these obligations may occur in the future. At December 31, 2012, FCX’s
environmental obligations totaled $2.4 billion on an undiscounted and unescalated basis (compared with $1.2 billion recorded on the balance sheet, which included environmental obligations assumed in the FMC acquisition at fair value). FCX estimates
it is reasonably possible that these obligations could range between $2.1 billion and $2.7 billion on an undiscounted and unescalated basis. 

FCX believes that there may be potential claims for recovery from third parties, including the U.S. government and other PRPs. These potential recoveries
are not recognized unless realization is considered probable. 
 At December 31, 2012, the most significant environmental obligations were
associated with the Pinal Creek site in Arizona; the Newtown Creek site in New York City; historical smelter sites principally located in Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania; and uranium mining sites in the western U.S. The
recorded environmental obligations for these sites totaled $1.0 billion at December 31, 2012. A discussion of these sites follows. 

Pinal Creek. The Pinal Creek site was listed under the Arizona Department of Environmental Quality’s (ADEQ) Water Quality Assurance Revolving
Fund program in 1989 for contamination in the shallow alluvial aquifers within the Pinal Creek drainage near Miami, Arizona. Since that time, environmental remediation was performed by members of the Pinal Creek Group (PCG), consisting of FMC Miami,
Inc. (Miami), a wholly owned subsidiary of FMC, and two other companies. In 1998, the District Court approved a Consent Decree between the PCG members and the state of Arizona resolving all matters related to an enforcement action contemplated by
the state of Arizona against the PCG members with respect to groundwater contamination. The Consent Decree committed the PCG members to complete the remediation work outlined in the Consent Decree, and that work continues at this time and is
expected to continue for many years in the future. Miami also was a party to litigation entitled Pinal Creek Group, et al. v. Newmont Mining Corporation, et al., United States District Court, District of Arizona, Case No. CIV 91-1764 PHX DAE
(LOA), filed on May 1, 1991. Pursuant to a settlement 







 
in 2010, Miami paid $40 million to certain members of the PCG to settle the allocation of previously incurred costs, and agreed to take full responsibility for future groundwater remediation at
the Pinal Creek site, with limited exceptions. The settlement did not result in a change to the obligation, which was estimated at fair value when assumed in the FMC acquisition. During 2011, the obligation was increased by $31 million to reflect
changes in remediation capping designs that incorporate best practices for side slope regrading and cap thickness. 
 Newtown Creek. From
the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of FMC, operated a smelter, and from the 1930s until 1984, it operated a refinery on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms
part of the boundary between Brooklyn and Queens in New York City. Heavy industrialization along the banks of the creek and discharges from the City of New York’s sewer system over more than a century resulted in significant environmental
contamination of the waterway. The New York Attorney General previously notified several companies, including PDRC, about possible obligations to clean up contaminated sediments in the creek. In March and April 2010, EPA notified PDRC and five
others that EPA considers them to be PRPs under CERCLA. The notified parties began working with EPA to identify other PRPs, and EPA proposed that the notified parties perform a Remedial Investigation/Feasibility Study (RI/FS) at their expense and
reimburse EPA for its oversight costs. EPA is not expected to propose a remedy until after a RI/FS is completed, which is expected to take several years. On September 29, 2010, EPA designated the creek as a Superfund site. Effective
July 18, 2011, PDRC and five other parties entered an Administrative Order on Consent (AOC) to perform a RI/FS to assess the nature and extent of environmental contamination in the creek and identify potential remedial options. The
parties’ RI/FS work under the AOC and their identification of other PRPs are ongoing. FCX’s financial obligation for this matter was estimated at fair value when it was assumed in the FMC acquisition and is included in FCX’s aggregate
environmental obligations. The actual costs of fulfilling this remedial obligation and the allocation of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remediation remedy ultimately selected by EPA and
related allocation determinations. Depending on the overall cost and the portion allocated to PDRC, that share could be material to FCX. 

Historical Smelter Sites. FMC and its predecessors at various times owned or operated copper and zinc smelters in several states, including
Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania. For some of these smelter sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating and, if appropriate, remediating
environmental conditions associated with the smelters. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate site conditions associated with the smelters. The
historical smelter sites are in various stages of assessment and remediation. The two most significant environmental obligations for historical smelter sites relate to Blackwell, Oklahoma, and Bisbee, Arizona. Adjustments to the environmental
obligations for historical smelter sites, which principally were estimated at fair value when assumed in the FMC acquisition, totaled a reduction of $47 







 
million in 2012, primarily because of changes in estimated timing of obligations, and an increase of $36 million in 2011, primarily at the Blackwell, Oklahoma, site (refer to discussion below).

 Blackwell. From 1918 to 1974, Blackwell Zinc Company, Inc. (BZC), an indirect subsidiary of FCX, owned and operated a zinc smelter in
Blackwell, Oklahoma. In 1974, the smelter was demolished and the property deeded to the Blackwell Industrial Authority. Pursuant to an administrative order with the state of Oklahoma, BZC undertook remedial actions in Blackwell in 1996 and 1997,
including sampling the nearby residential and commercial properties, and removing soils on properties that were found to have metal concentrations above state-established cleanup standards. From 1997 to 2003, BZC investigated the nature and extent
of groundwater contamination potentially attributable to the former smelter and evaluated options for remedying such contamination. In 2003, the state of Oklahoma adopted a cleanup plan requiring the installation of a groundwater extraction and
treatment system and the closure of domestic groundwater wells within the groundwater plume area. BZC completed the construction of a groundwater extraction and treatment system, with system startup and initial discharge of treated water occurring
in October 2010. 
 Between 2007 through 2012, FCX, on behalf of BZC, completed a voluntary soil remediation program by inviting property owners
in and around Blackwell to have soil at their properties sampled for the presence of smelter-related contaminants, and offering to remediate properties whose soils were found to have metal concentrations above state-established cleanup standards. As
part of this program, FCX sampled soils on approximately 90 percent of the residential properties in Blackwell and remediated soils on about 600 properties. All of these soil sampling and remediation activities were coordinated with, and supervised
by, the state of Oklahoma. 
 On May 23, 2012, the Board of Commissioners of Kay County, Oklahoma, filed suit in Oklahoma District Court
against FCX and several affiliates, including BZC, entitled Board of Commissioners of the County of Kay, Oklahoma v. Freeport-McMoRan Copper & Gold Inc., et al., United States District Court, Western District of Oklahoma, Case
No. 5:12-cv-00601-C. On May 25, 2012, the case was removed to the United States District Court for the Western District of Oklahoma, and trial is set for October 2013. The suit alleges BZC permitted large quantities of smelter waste to be
used as road building and fill material throughout Kay County over a period of decades and seeks unspecified financial assistance for removing and covering much of the material, and unspecified damages for the alleged public nuisance created by the
presence of the material. FCX has asserted a counter claim against Kay County for contribution under CERCLA. Separate from the litigation, in fourth-quarter 2012, BZC entered into a Consent Agreement and Final Order with the Oklahoma Department of
Environmental Quality and Kay County to conduct an assessment of smelter material present on Kay County’s roads, bridges and associated rights-of-way. Sampling is expected to be completed in 2013. 

Bisbee. From the 1880s until 1975, FMC and certain predecessor and subsidiary entities operated a copper mine near Bisbee, Arizona. A series of
smelters operated in Bisbee 







 
from approximately 1879 through 1908. In 2000, FMC entered the Bisbee area into the Arizona Voluntary Remediation Program (VRP) administered by ADEQ. In 2008, FMC expanded the VRP project to
include other communities near Bisbee and commenced a voluntary community outreach program inviting property owners to have soils at their properties sampled for the presence of smelter and mine-related metals. For property owners whose soils are
found to have metal concentrations above ADEQ established cleanup standards, FMC has offered to remove the impacted soils and replace them with clean soils. For those property owners who requested sampling, approximately 40 percent require some
level of cleanup. At December 31, 2012, approximately 60 percent of owners who agreed to have soil cleanup on their properties was completed. 
 Uranium Mining Sites. During a period between 1940 and the early 1970s, certain FMC predecessor entities were involved in uranium exploration and mining in the western U.S. Similar exploration and
mining activities by other companies have caused environmental impacts that have warranted remediation, and EPA and local authorities are currently evaluating the need for significant cleanup activities in the region. To date, FMC has undertaken
remediation at a limited number of sites associated with these predecessor entities. An initiative to gather additional information about sites in the region is ongoing, and information gathered under this initiative was submitted to EPA Region 9
during the second and third quarters of 2008 and the fourth quarter of 2009 in response to an information request by EPA regarding uranium mining activities on Navajo Nation properties. FCX utilized the results of FMC’s remediation experience,
in combination with historical and updated information to initially estimate the fair value of uranium-related liabilities assumed in the FMC acquisition. 
 Asset Retirement Obligations (AROs). FCX’s ARO cost estimates are reflected on a third-party cost basis and comply with FCX’s legal obligation to retire tangible, long-lived assets. A
summary of changes in FCX’s AROs for the year ended December 31, 2012 (in millions) follows: 
  

					
	 Balance at beginning of year
	  	$	921	  
	 Liabilities incurred
	  	 	6	  
	 Revisions to cash flow estimates (a)
	  	 	211	  
	 Accretion expense
	  	 	55	  
	 Spending

	 Balance at end of year
	  	 	1,146	  
	 Less current portion
	  	 	(55	) 
		  	  
	  
	 
	 Long-term portion
	  	$	1,091	  
		  	  
	  
	 

  

	(a)	Revisions to cash flow estimates were primarily related to updated closure plans that included revised cost estimates and accelerated timing of certain closure
activities. 

 ARO costs may increase or decrease significantly in the future as a result of changes in regulations, changes in
engineering designs and technology, permit modifications or updates, changes in mine plans, inflation or other factors and as actual reclamation spending occurs. ARO activities and expenditures generally are made over an extended period of time
commencing near the end of the mine life; however, certain reclamation activities may be accelerated if legally required or if determined to be economically beneficial. 







 Legal requirements in New Mexico, Arizona and Colorado require financial assurance to be provided for the
estimated costs of reclamation and closure, including groundwater quality protection programs. FCX has satisfied financial assurance requirements by using a variety of mechanisms, such as performance guarantees, financial capability demonstrations,
trust funds, surety bonds, letters of credit and collateral. The applicable regulations specify financial strength tests that are designed to confirm a company’s or guarantor’s financial capability to fund estimated reclamation and closure
costs. The amount of financial assurance FCX is required to provide will vary with changes in laws, regulations and reclamation and closure requirements, and cost estimates. At December 31, 2012, FCX’s financial assurance obligations
associated with these closure and reclamation costs totaled $946 million, of which approximately $582 million was in the form of guarantees issued by FCX and financial capability demonstrations. At December 31, 2012, FCX had trust assets
totaling $161 million, which are legally restricted to fund a portion of its AROs for properties in New Mexico as required by New Mexico regulatory authorities. 
 New Mexico Environmental and Reclamation Programs. FCX’s New Mexico operations are regulated under the New Mexico Water Quality Act and regulations adopted under that act by the Water Quality
Control Commission (WQCC). The New Mexico Environment Department (NMED) has required each of these operations to submit closure plans for NMED’s approval. The closure plans must include measures to assure meeting groundwater quality standards
following the closure of discharging facilities and to abate any groundwater or surface water contamination. In March 2009, the Tyrone operation appealed the WQCC Final Order, dated February 4, 2009, regarding location of the “places of
withdrawal of water,” a legal criterion used to determine where groundwater quality standards must be met at FCX’s New Mexico mining sites. In December 2010, Tyrone entered into a settlement agreement with NMED that calls for a stay of the
appeal while NMED and the WQCC complete several administrative actions, including renewal of Tyrone’s closure permit consistent with the terms of the settlement, review and approval of a groundwater abatement plan and adoption of alternative
abatement standards, and adoption of new groundwater discharge permit rules for copper mines. If the administrative actions are concluded consistent with the terms of the settlement agreement within the period of the stay, then Tyrone will move to
dismiss the appeal. In December 2012, Tyrone and NMED agreed to extend the period to conclude the administrative actions through December 31, 2013. The Court of Appeals also extended the stay for another year. Finalized closure plan
requirements, including those resulting from the actions to be taken under the settlement agreement, could result in increases in the Tyrone, Chino and Cobre closure costs. 
 FCX’s New Mexico operations also are subject to regulation under the 1993 New Mexico Mining Act (the Mining Act) and the related rules that are administered by the Mining and Minerals Division (MMD)
of the New Mexico Energy, Minerals and Natural Resources Department. Under the Mining Act, mines are required to obtain approval of 







 
plans describing the reclamation to be performed following cessation of mining operations. At December 31, 2012, FCX had accrued reclamation and closure costs of $476 million for its New
Mexico operations. As stated above, additional accruals may be required based on the state’s review of FCX’s updated closure plans and any resulting permit conditions, and the amount of those accruals could be material. 

Arizona Environmental and Reclamation Programs. FCX’s Arizona properties are subject to regulatory oversight in several areas. ADEQ has
adopted regulations for its aquifer protection permit (APP) program that require permits for, among other things, certain facilities, activities and structures used for mining, concentrating and smelting and require compliance with aquifer water
quality standards at an applicable point of compliance well or location. The APP program also may require mitigation and discharge reduction or elimination of some discharges. 
 An application for an APP requires a description of a closure strategy that will meet applicable groundwater protection requirements following cessation of operations and an estimate of the cost to
implement the closure strategy. An APP may specify closure requirements, which may include post-closure monitoring and maintenance. A more detailed closure plan must be submitted within 90 days after a permitted entity notifies ADEQ of its intent to
cease operations. A permit applicant must demonstrate its financial ability to meet the closure costs estimated in the APP. 
 Portions of
Arizona mining facilities that operated after January 1, 1986, also are subject to the Arizona Mined Land Reclamation Act (AMLRA). AMLRA requires reclamation to achieve stability and safety consistent with post-mining land use objectives
specified in a reclamation plan. Reclamation plans must be approved by the State Mine Inspector and must include an estimate of the cost to perform the reclamation measures specified in the plan. FCX will continue to evaluate options for future
reclamation and closure activities at its operating and non-operating sites, which are likely to result in adjustments to FCX’s ARO liabilities. At December 31, 2012, FCX had accrued reclamation and closure costs of $240 million for its
Arizona operations. 
 Colorado Reclamation Programs. FCX’s Colorado operations are regulated by the Colorado Mined Land Reclamation
Act (Reclamation Act) and regulations promulgated thereunder. Under the Reclamation Act, mines are required to obtain approval of reclamation plans describing the reclamation of lands affected by mining operations to be performed during mining or
upon cessation of mining operations. As of December 31, 2012, FCX had accrued reclamation and closure costs of $47 million for its Colorado operations. 
 Chilean Reclamation and Closure Programs. In July 2011, the Chilean senate passed legislation regulating mine closure, which establishes new requirements for closure plans and became effective in
November 2012. FCX’s Chilean operations will be required to update closure plans and provide financial assurance for these obligations. FCX cannot predict at this time the cost of these closure plans or the levels or forms of financial
assurance that may be required. Revised closure plans for the Chilean mine sites are due in November 2014. At December 31, 2012, FCX had accrued reclamation and closure costs of $54 million for its Chilean operations. 







 Peruvian Reclamation and Closure Programs. Cerro Verde is subject to regulation under the Mine
Closure Law administered by the Peruvian Ministry of Energy and Mines. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and
post-closure plans and financial assurance. The updated closure plan for the Cerro Verde mine expansion must be submitted to the Peruvian regulatory authorities in December 2014. At December 31, 2012, Cerro Verde had accrued reclamation and
closure costs of $89 million. 
 PT Freeport Indonesia Reclamation and Closure Programs. The ultimate amount of reclamation and closure
costs to be incurred at PT Freeport Indonesia’s operations will be determined based on applicable laws and regulations and PT Freeport Indonesia’s assessment of appropriate remedial activities in the circumstances, after consultation with
governmental authorities, affected local residents and other affected parties and cannot currently be projected with precision. Estimates of the ultimate reclamation and closure costs PT Freeport Indonesia will incur in the future involve complex
issues requiring integrated assessments over a period of many years and are subject to revision over time as more complete studies are performed. Some reclamation costs will be incurred during mining activities, while most closure costs and the
remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue for approximately 30 years. At December 31, 2012, PT Freeport Indonesia had accrued reclamation and closure costs of $195
million and a long-term receivable for Rio Tinto’s share of the obligation of $18 million (included in long-term receivables). 
 In 1996,
PT Freeport Indonesia began contributing to a cash fund ($16 million balance at December 31, 2012) designed to accumulate at least $100 million (including interest) by the end of its Indonesia mining activities. PT Freeport Indonesia plans to
use this fund, including accrued interest, to pay mine closure and reclamation costs. Any costs in excess of the $100 million fund would be funded by operational cash flow or other sources. 
 In December 2010, the President of Indonesia issued a regulation regarding mine reclamation and closure, which requires a company to provide a mine closure guarantee in the form of a time deposit placed
in a state-owned bank in Indonesia. In accordance with its Contract of Work, PT Freeport Indonesia is working with the Department of Energy and Mineral Resources to review these requirements, including discussion of other options for the mine
closure guarantee. In December 2009, PT Freeport Indonesia submitted its revised mine closure plan to the Department of Energy and Mineral Resources for review and has addressed comments received during the course of this review process. 








 Litigation. 
 Asbestos Claims. Since approximately 1990, FMC and various subsidiaries have been named as defendants in a large number of lawsuits that claim personal injury either from exposure to asbestos
allegedly contained in electrical wire products produced or marketed many years ago or from asbestos contained in buildings and facilities located at properties owned or operated by FMC affiliates, or from alleged asbestos in talc products. Many of
these suits involve a large number of codefendants. Based on litigation results to date and facts currently known, FCX believes there is a reasonable possibility that losses may have been incurred related to these matters; however, FCX also believes
that the amounts of any such losses, individually or in the aggregate, are not material to its consolidated financial statements. There can be no assurance, however, that future developments will not alter this conclusion. 

Yonkers Site. From 1932 until 1984, FMC owned and operated a cable manufacturing facility on the Hudson River in Yonkers, New York. FMC sold that
operation in 1984, and it was subsequently sold to BICC Cables Corporation (BICC). BICC closed the facility in 1996. In 2005, Blackacre Partners OPS, LLC (Blackacre) began environmental cleanup work at the site using funding provided by FMC and
BICC. One Point Street, Inc. (OPS), a real estate developer, has current title to the site. 
 On September 9, 2011, OPS filed a complaint
in the United States District Court for the Southern District of New York, which it amended on March 1, 2012. The amended complaint alleged that FMC, BICC and Blackacre failed to timely and diligently complete remediation of the site in breach
of alleged obligations under CERCLA and New York Environmental Conservation Law, and under the contractual agreements among the parties. In fourth-quarter 2012, this matter was settled, and OPS will be completing the limited remaining cleanup work
at the site using funds provided by FMC and BICC. 
 Columbian Chemicals Company (Columbian) Claims. Columbian, formerly a subsidiary of
FMC, has notified FCX of various indemnification claims arising out of the 2005 agreement pursuant to which Columbian was sold. The principal outstanding claims relate to (1) multiple mass tort suits pending against Columbian in West Virginia
state court for alleged personal injury and property damage resulting from exposure to carbon black (the Carbon Black claims) and (2) an investigation being conducted by EPA of potential Clean Air Act violations during the period Columbian was
owned by FMC (the Clean Air Act matter). In April 2012, Columbian filed suit in New York state court (Columbian Chemicals Company and Columbian Chemicals Acquisition LLC v. Freeport-McMoRan Corporation f/k/a Phelps Dodge Corporation, County
of New York, Supreme Court of the State of New York, Index No. 600999/2010), that alleged, among other things, that the Carbon Black claims are the responsibility of FMC, and are not subject to the aggregate cap under the 2005 agreement pursuant to
which Columbian was sold. In July 2012, FCX and Columbian reached a settlement pursuant to which the litigation was dismissed with prejudice and all outstanding disputes regarding the extent of FCX’s indemnity obligations to Columbian were
fully resolved. Under the terms of the settlement, FCX’s remaining possible exposure is to indemnify Columbian for incurred losses related only to the Carbon Black claims and the Clean Air Act matter. The cap, net








 
of amounts reserved and paid, totaled $122 million at December 31, 2012. FMC cannot estimate Columbian’s exposure, if any, for the Carbon Black claims or the Clean Air Act matter.

 Shareholder Litigation. Thirteen derivative actions challenging the PXP merger and/or the MMR merger were filed on behalf of FCX by
purported FCX stockholders. Ten were filed in the Court of Chancery of the State of Delaware and three were filed in the Superior Court of the State of Arizona, County of Maricopa. On January 25, 2013, the Delaware Court of Chancery
consolidated the Delaware actions into a single action, In Re Freeport-McMoRan Copper & Gold Inc. Derivative Litigation, No. 8145-VCN. On January 17, 2013, the Arizona Superior Court consolidated two of the Arizona actions
into In Re Freeport-McMoRan Derivative Litigation, No. CV2012-018351. A third Arizona complaint, Harris v. Adkerson et al., No. CV2013-004163, filed on January 16, 2013, has not yet been consolidated. The actions name some or all of the
following as defendants: the directors and certain officers of FCX, two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions allege, among other things, that the FCX directors breached
their fiduciary duties to FCX stockholders because they, among other things, pursued their own interests at the expense of stockholders in approving the PXP and MMR mergers. The complaints also allege that some or all of the following parties aided
and abetted the wrongful acts allegedly committed by the directors and certain officers of FCX: two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions seek as relief, among other
things, an injunction barring or rescinding both the PXP merger and the MMR merger and requiring submission of the proposed PXP merger and MMR merger to a vote of FCX stockholders, damages, and attorneys’ fees and costs. 

Three putative class actions challenging the PXP merger were filed on behalf of PXP stockholders in the Court of Chancery of the State of Delaware. On
January 15, 2013, the Court of Chancery consolidated the actions into a single action, In Re Plains Exploration & Production Company Stockholder Litigation, No. 8090-VCN. The action names as defendants PXP, the directors of
PXP, FCX, and an FCX subsidiary. The action alleges that PXP’s directors breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with
respect to the merger, and that FCX and an FCX subsidiary aided and abetted the breach of fiduciary duties by PXP’s directors. The action seeks as relief an injunction barring or rescinding the PXP merger, damages, and attorneys’ fees and
costs. 
 In addition, ten putative class actions challenging the MMR merger were filed on behalf of MMR stockholders. Nine were filed in the
Court of Chancery of the State of Delaware. On January 25, 2012, the Court of Chancery consolidated the actions into a single action, In Re McMoRan Exploration Co. Stockholder Litigation, No. 8132-VCN. One action was also filed in
the Civil District Court for the Parish of Orleans of the State of Louisiana: Langley v. Moffett et al., No. 2012-11904, filed December 19, 2012. Each of the actions names some or all of the following as defendants, in addition to
MMR and its directors: FCX, subsidiaries of FCX, and PXP. The actions allege that MMR’s directors 







 
breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with respect to the merger,
and that PXP, FCX, or both, aided and abetted the breach of fiduciary duty by MMR’s directors. The Delaware action also asserts claims derivatively on behalf of MMR. The actions seek, among other things, injunctive relief barring or rescinding
the MMR merger, damages, and attorneys’ fees and costs. 
 FCX intends to vigorously defend itself in these matters. 

Tax Matters. Cerro Verde Tax Proceedings. SUNAT, the Peruvian national tax authority, has assessed mining royalties on materials processed
by the Cerro Verde concentrator that commenced operations in late 2006. These assessments cover the period October 2006 to December 2007 and the years 2008 and 2009. SUNAT has issued rulings denying Cerro Verde’s protest of the assessments.
Cerro Verde has appealed these decisions and currently has three cases pending before the Peruvian Tax Court. Cerro Verde is challenging these royalties because it believes its stability agreement provides an exemption for all minerals extracted
from its mining concession, irrespective of the method used for processing those minerals. Although FCX believes its interpretation of the stability agreement is correct, if Cerro Verde is ultimately found responsible for these assessments, it will
also be liable for interest, which accrues at rates that range from approximately 7 to 18 percent based on the year accrued and the currency in which the amounts would be payable. At December 31, 2012, the aggregate amount of the assessments,
including interest and penalties, totaled $218 million. SUNAT may continue to assess mining royalties annually until this matter is resolved by the Peruvian Tax Tribunal. 
 Cerro Verde is also challenging various income and value-added tax assessments from SUNAT covering the years 2002 through 2008 and has cases pending before the Peruvian Tax Court. At December 31,
2012, the approximate amount of these assessments, including interest and penalties, totaled $180 million. 
 Indonesia Tax Matters. The
Indonesian tax authorities issued assessments for various audit exceptions on PT Freeport Indonesia’s tax returns as follows (in millions): 
  

																	
	 Date of Assessment
	  	Tax Return
Year	 	  	Tax
Assessment	 	  	Interest

 PT Freeport Indonesia has filed objections to the assessments because it believes it has properly paid its taxes. During
first-quarter 2012, PT Freeport Indonesia’s objections to the assessments related to 2005 were substantially all rejected by the Indonesian tax authorities and, in May 2012, appeals were filed with the Indonesian Tax Court. As of








 
December 31, 2012, PT Freeport Indonesia has paid $182 million (of which $148 million is included in long-term receivables) for the disputed tax assessments related to 2005, 2006 and 2007.
PT Freeport Indonesia is working with the Indonesian tax authorities to resolve these matters and expects to receive additional assessments from the Indonesian tax authorities for their audit of its 2008 tax return. 

In December 2009, PT Freeport Indonesia was notified by the Large Taxpayer’s Office of the Government of Indonesia of its view that PT Freeport
Indonesia is obligated to pay value added taxes on certain goods imported after the year 2000. The amount of such taxes and related penalties under this view would be significant. PT Freeport Indonesia believes that, pursuant to the terms of its
Contract of Work, it is only required to pay value added taxes on these types of goods imported after December 30, 2009. PT Freeport Indonesia has not received a formal assessment and is working with the applicable government authorities to
resolve this matter. 
 Letters of Credit, Bank Guarantees and Surety Bonds. Letters of credit and bank guarantees totaled $98 million at
December 31, 2012, primarily for reclamation and environmental obligations, workers’ compensation insurance programs, tax and customs obligations, and other commercial obligations. In addition, FCX had surety bonds totaling $159 million at
December 31, 2012, associated with reclamation and closure ($137 million – see discussion above), self-insurance bonds primarily for workers’ compensation ($18 million) and other bonds ($4 million). 

Insurance. FCX purchases a variety of insurance products to mitigate potential losses. The various insurance products typically have specified
deductible amounts or self-insured retentions and policy limits. FCX generally is self-insured for U.S. workers’ compensation, but purchases excess insurance up to statutory limits. An actuarial analysis is performed twice a year for various
FCX casualty programs, including workers’ compensation, to estimate required insurance reserves. Insurance reserves totaled $52 million at December 31, 2012, which consisted of a current portion of $8 million (included in accounts payable
and accrued liabilities) and a long-term portion of $44 million (included in other liabilities). 
 FCX maintains property damage and business
interruption insurance related to its operations. FCX and its insurers entered into an insurance settlement agreement in December 2012. The insurers agreed to pay an aggregate of $63 million, including $4 million for PT Freeport Indonesia’s
joint venture partner’s interest, for the settlement of the insurance claim for business interruption and property damage relating to the 2011 incidents affecting PT Freeport Indonesia’s concentrate pipelines. As a result of the
settlement, FCX recorded a gain of $59 million ($31 million to net income attributable to FCX common stockholders).

 EXHIBIT E-2 
 FORM OF OPINION OF JONES, WALKER, WÆCHTER, POITEVANT, CARRÈRE & DENÈGRE, L.L.P., U.S. COUNSEL FOR THE BORROWERS AND THE SUBSIDIARIES – PXP CLOSING DATE

 Administrative Agent and 
 Syndication Agent 
 referred to below 
 c/o JPMorgan Chase Bank, N.A. 
 270 Park Avenue 

New York, New York 10017 
  

	 	Re:	Freeport-McMoRan Copper & Gold Inc. 


Ladies and Gentlemen: 
 We have
served as counsel to Freeport-McMoRan Copper & Gold Inc., a Delaware corporation (“FCX”), and [IMONC, LLC], a Delaware limited liability company (“IMONC”, and together with FCX and [the subsidiaries of FCX
and IMONC listed on the signature pages of the Guarantee Agreement referred to below that have Delaware as their jurisdiction of formation (the “Delaware Subsidiary Guarantors”)], the “Loan Parties”), in connection
with (i) the preparation, execution and delivery by the Loan Parties [(other than the Delaware Subsidiary Guarantors)] of the Term Credit Agreement dated as of February [14], 2013 (the “Credit Agreement”) among FCX, IMONC, the
issuing banks party thereto (the “Issuing Banks”), JPMorgan Chase Bank, N.A., as administrative agent (in such capacity, the “Administrative Agent”), and Bank of America, N.A., as Syndication Agent (in such capacity
“Syndication Agent”), and (ii) the transactions contemplated thereby. This opinion is delivered pursuant to Section 4.04(b)(ii) of the Credit Agreement. Capitalized terms not otherwise defined herein shall have the
meanings set forth in the Credit Agreement. 
 In connection with this opinion, we have examined executed originals or copies as
executed of the following documents: 
  

	 	(1)	The Credit Agreement; 

  

	 	(2)	The Co-Borrower Joinder dated as of the date hereof, between IMONC and the Administrative Agent; 









	 	(3)	[The Guarantee Agreement dated as of the date hereof, among the subsidiaries of FCX and IMONC listed on the signature pages thereof and the Administrative Agent;] and


  

	 	(4)	Each promissory note dated the date hereof and issued pursuant to Section 2.09(e) of the Credit Agreement. 


The documents listed in items (1) through [(4)] are hereinafter collectively referred to as the “Financing
Documents”. 
 In addition, we have examined the certificate of incorporation and by-laws of FCX, the certificate of
formation and limited liability company agreement of IMONC [and certificates of incorporation or equivalent charter documents and the by-laws or equivalent governing documents of each Delaware Subsidiary Guarantor] (in each case, as amended through
the date hereof). For purposes of the opinions in paragraph 1 below, we have relied exclusively upon certificates issued by the Secretary of State of the State of Delaware and such opinions are not intended to provide any conclusion or assurance
beyond that conveyed by such certificates. 
 We have also examined originals, or copies certified or otherwise identified to
our satisfaction as originals, of such agreements, documents, certificates, consents, resolutions and statements of public officials and corporate officers and representatives and have made such investigations as we have deemed relevant and
necessary in order to render the opinions contained herein. As to any facts material to our opinion, we have relied upon factual representations made in or pursuant to the Financing Documents and the documents referred to therein by the various
parties thereto, and, in addition, we have, when relevant facts were not independently established by us, relied, to the extent we deemed such reliance proper, upon a certificate or certificates or other written or oral advice of an official,
officer, authorized representative or member of the particular governmental authority, corporation, firm or other person or entity concerned. 
 In our examination, we have also assumed, with your permission and without independent verification: 
 (i) the genuineness of all signatures on all documents and instruments examined by us; 
 (ii) the legal capacity of all natural persons who have signed documents and instruments examined by us; 
 (iii) the authenticity and completeness of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as conformed, certified or photostatic
copies and the authenticity of the originals of such copies; 
 (iv) the factual accuracy and completeness of all certificates
submitted to us and of each of the representations and warranties as to matters of fact made in the Financing Documents by each of the parties thereto; 

  
 2 








 (v) that each of the parties to the Financing Documents, other than the Loan Parties, is
duly organized or formed, validly existing and in good standing under the laws of its jurisdiction of organization or formation and has all requisite power and authority to enter into and perform its respective obligations in connection with the
transactions described in the Financing Documents, each of the Financing Documents has been duly authorized, executed and delivered by each of the parties thereto, other than the Loan Parties, and each of the Financing Documents constitutes the
legal, valid and binding obligations of each one of the parties thereto, other than the Loan Parties, under the laws of all jurisdictions applicable thereto; 
 (vi) the accuracy and completeness of all corporate records made available to us by the Loan Parties; 
 (vii) each party to the Financing Documents, other than the Loan Parties, has complied with all legal requirements pertaining to its status, insofar as such status relates to its rights to enforce the
Financing Documents against the Loan Parties and the execution, delivery and performance by each party to the Financing Documents, other than the Loan Parties, do not (a) contravene such party’s articles of association, bylaws or similar
organizational documents, (b) contravene any judicial or administrative judgment, injunction, order or decree that is binding upon such party or its property or assets, (c) violate, or require the consent not obtained under, any
contractual obligation applicable to or binding upon such party or (d) contravene any laws and governmental rules and regulations that may be applicable to such party; 
 (viii) that there are no other agreements or understandings among the parties to the Financing Documents, written or oral, and there is no usage of trade or course of prior dealing among the parties
thereto that would, in any case, define, supplement or qualify the terms of the Financing Documents; 
 (ix) all authorizations,
approvals or consents of, and all filings or registrations with, any governmental or regulatory authority or agency required under the federal laws of the United States of America, the laws of New York or Delaware or any other jurisdiction for the
execution, delivery and performance of the Financing Documents have been obtained or effected and are in full force and effect; provided, however, that the assumption set forth in this subparagraph (ix) is not made in respect of
any such action which is expressly addressed in our opinion in paragraph 4 below; and 
 (x) that the choice of New York law to
govern the Credit Agreement, which is stated therein to be governed thereby, is legal and valid under the laws of other applicable jurisdictions and that insofar as any obligation under any of the Credit Agreement is to be performed in any
jurisdiction outside the United States of America its performance will not be illegal or ineffective by virtue of the law of that jurisdiction. 
 Unless otherwise indicated, whenever our opinion is given with respect to the existence or absence of facts (or legal conclusions which necessarily are based upon the existence or absence of facts) and is
indicated to be based on our knowledge, it is intended to signify that, during the course of our representation of the Loan Parties, in connection with the transactions contemplated by the Financing Documents, no information has come to our
attention which 

  
 3 








 
would give us actual knowledge of the existence or absence of such facts. However, except to the extent expressly set forth herein, we have not undertaken any independent investigation to
determine or verify the existence or absence of such facts, and no inference as to our knowledge of the existence or absence of such facts should be drawn from our representation of the Loan Parties, as stated above. 

This opinion is limited to (i) applicable federal laws and jurisprudence, (ii) the laws set forth in the Delaware Limited
Liability Company Act (the “DLLCA”) and (iii) the General Corporation Law of the State of Delaware (“DGCL”), but, with respect to clauses (ii) and (iii), only to the extent necessary to render the opinions
in paragraphs 1, 3 and 4 below, in each case as of the date hereof, and we express no opinion with respect to the laws of any other state or jurisdiction. 
 Based upon the foregoing and in reliance thereon and upon such other investigations as we have deemed necessary, and subject to the assumptions, limitations, qualifications and exceptions set forth
herein, we are of the opinion that: 
 1. FCX is duly incorporated, validly existing and in good standing under the laws of the
State of Delaware. IMONC[ and each Delaware Subsidiary Guarantor ]is duly formed, validly existing and in good standing under the laws of the State of Delaware. 
 2. Each of the Loan Parties has the corporate or limited liability company, as applicable, power and authority to (a) own its property and assets and to carry on its business as now conducted and as
proposed to be conducted and (b) execute, deliver and perform its obligations under the Financing Documents to which it is a party. 
 3. The Financing Documents have been duly authorized by all necessary corporate or limited liability company, as applicable, action on the part of each Loan Party that is a party thereto and have been
duly executed and delivered by such Person. The execution, delivery and performance by each Loan Party of its agreements and obligations under the Financing Documents to which it is a party will not (i) conflict with or result in a breach or
violation of any of the terms and provisions of the certificate of incorporation, certificate of formation, by-laws, limited liability company agreement or other organizational documents of such Person, each as in effect on the date hereof, or
(ii) violate any law, statute, rule or regulation of the DLLCA or the DGCL, as applicable. 
 4. Except as disclosed in the
Credit Agreement, no consent, approval, authorization, declaration, registration, filing with or order of any Delaware (but only to the extent required by the DGCL or the DLLCA) court or governmental agency or body is or will be required in order
for any of the Loan Parties to (a) execute and deliver the Financing Documents to which it is a party and to perform its respective obligations thereunder, (b) in the case of FCX and IMONC, borrow under the Credit Agreement or [(c) in the
case of the Delaware Subsidiary Guarantors, guarantee the Obligations]. 
 5. Except for Disclosed Matters and other than
Excluded Matters, there are no actions, suits or proceedings at law or in equity or by or before any governmental instrumentality 

  
 4 








 
or other agency or regulatory authority now pending or, to the best of our knowledge, threatened against or affecting FCX or any of the consolidated subsidiaries of FCX or the businesses, assets
or rights of FCX or any of the consolidated subsidiaries of FCX as to which there is (a) a reasonable possibility of an adverse determination and (b) which, if adversely determined, could materially and adversely affect (i) the
businesses, operations or financial condition, of FCX and its consolidated subsidiaries, taken as a whole, or (ii) the ability of any Loan Party to perform its obligations under the Financing Documents to which it is a party. We express no
opinion with respect to actions, suits or proceedings at law or in equity or by or before any governmental instrumentality or other agency or regulatory authority now pending or threatened against or affecting IMONC and any subsidiary of IMONC.

 For purposes of this paragraph 5, 
 “Disclosed Matters” means those matters listed on Exhibit A attached hereto. 
 “Excluded Matters” means any actions, suits or proceedings at law or in equity or by or before any Governmental Authority now pending or threatened against or affecting IMONC and any
subsidiary of IMONC. 
 The foregoing opinions are subject to the following qualifications, exceptions and limitations:

  

	 	(A)	Without limiting the generality of the foregoing, we express no opinion, in any case, with respect to: 


(i) (a) any laws, rules or regulations relating to (1) pollution or protection of the environment, (2) labor, employee
rights and benefits, ERISA or occupational safety and health, (3) antitrust, (4) securities, (5) tax, (6) federal or state utility or energy regulation, (7) bank regulatory matters, (8) corrupt practices, including,
without, limitation, the Foreign Corrupt Practices Act, (b) any laws, rules, or regulations of any county, parish, municipality or similar subdivision of any state and (c) any other laws to the extent not customarily applicable to
transactions of the type contemplated by the Credit Agreement; 
 (ii) the application of any fraudulent conveyance, fraudulent
transfer, fraudulent obligation or similar law; 
 (iii) the effect of the compliance or noncompliance of the Administrative
Agent or any Lender with any federal, state, local or foreign laws or regulations applicable to the Administrative Agent or any Lender or the Administrative Agent’s or any Lender’s business or the maximum rate of interest chargeable or
collectible by the Administrative Agent or any Lender under applicable statutes and regulations; and 
 (iv) any law,
governmental rule, regulation, or guideline, or any judgment, writ, order, injunction, award, or decree of any court, arbitrator, administrative agency, or other Governmental Authority relating in any way to any environmental or antitrust matter.


  
 5 








 (B) We express no opinion as to the enforceability of the Credit Agreement or any provisions
therein. 
 (C) The opinions set forth herein are further qualified and limited by the following: 

(i) bankruptcy, insolvency, reorganization, moratorium, receivership and other laws now or hereafter in effect relating to or affecting
the enforcement of creditors’ rights generally; 
 (ii) the effect of general principles of equity, including, without
limitation, concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, whether such enforceability is considered in a proceeding in equity or at law, and the
discretion of the court before which any such proceeding may be brought; 
 (iii) public policy considerations or court
decisions that may limit the rights of any party to obtain certain remedies and to indemnification, including indemnification for tortious or criminal acts or violations of law; and 

(iv) the fact that cumulative remedies may not be enforceable to the extent that they purport to or would have the effect of compensating
the party entitled to the benefits thereof in amounts in excess of the actual loss suffered by such party or to the extent that enforcement thereof would violate applicable laws concerning real estate or mixed collateral foreclosures or election of
remedies; and 
 The opinions expressed herein are limited to the specific issues addressed herein and are expressed as
of the date hereof and are not intended to have any prospective effect. We assume no obligation to advise you or any other Person of any changes concerning the above, whether or not deemed material, which may hereafter come or be brought to our
attention, including but not limited to, changes which could result from pending or future legislation, law or jurisprudence. An action, suit or other proceeding is deemed “pending” for purposes of this opinion letter when service of
process relating thereto has been served upon the applicable party. 
 The foregoing expresses our legal opinion as to
the matters set forth above and is based upon our professional knowledge and judgment at this time; it is not, however, to be construed as a guarantee, nor is it a warranty that a court considering such matters would not rule in a manner contrary to
the opinions set forth above. 
 The opinions set forth herein are rendered solely to the Agents, the Issuing Banks and the
Lenders (including their assignees and participants under the Credit Agreement) and are solely for the benefit of such parties in connection with the above transaction and may not be relied upon by them for any other purpose. This letter may not be
delivered to or relied upon by any other person or entity for any purpose without the prior written consent of this firm. This letter is not to be quoted in whole or in part or otherwise referred to in any financial statements or other public
releases, nor is it to be filed with any governmental agency or other person or entity, without the prior written consent of this firm.

 EXHIBIT A 
 Disclosed Matters 
 Environmental. FCX incurred environmental capital expenditures
and other environmental costs (including joint venture partners’ share) to comply with applicable environmental laws and regulations that affect its operations totaling $599 million in 2012. 

FCX subsidiaries that operate in the U.S. are subject to various federal, state and local environmental laws and regulations that govern emissions of air
pollutants; discharges of water pollutants; and generation, handling, storage and disposal of hazardous substances, hazardous wastes and other toxic materials. FCX subsidiaries that operate in the U.S. also are subject to potential liabilities
arising under CERCLA or similar state laws that impose responsibility on current and previous owners and operators of a facility for the cleanup of hazardous substances released from the facility into the environment, including damages to natural
resources, irrespective of when the damage to the environment occurred or who caused it. This cleanup liability also extends to persons who arranged for the disposal of hazardous substances or transported the hazardous substances to a disposal site
selected by the transporter. This liability often is shared on a joint and several basis meaning that each responsible party is fully responsible for the cleanup, although in many cases some or all of the other historical owners or operators no
longer exist, do not have the financial ability to respond or cannot be found. As a result, because of FCX’s acquisition of Phelps Dodge Corporation (name changed to Freeport-McMoRan Corporation, referred to as FMC) in 2007, many of the
subsidiary companies FCX now owns are responsible for a wide variety of environmental remediation projects throughout the U.S. FCX expects to spend substantial sums annually for many years to address those remediation issues. Certain FCX
subsidiaries have been advised by the U.S. Environmental Protection Agency (EPA), the Department of the Interior, the Department of Agriculture and several state agencies that, under CERCLA or similar state laws and regulations, they may be liable
for costs of responding to environmental conditions at a number of sites that have been or are being investigated to determine whether releases of hazardous substances have occurred and, if so, to develop and implement remedial actions to address
environmental concerns. FCX is also subject to claims where the release of hazardous substances is alleged to have damaged natural resources (NRD). As of December 31, 2012, FCX had more than 100 active remediation projects, including NRD
claims, in the U.S. in 28 states.

	(a)	Represented accretion of the fair value of environmental obligations assumed in the 2007 acquisition of FMC, which were determined on a discounted cash flow basis.



	(b)	Reductions primarily reflected adjustments for changes in the anticipated scope and timing of environmental remediation projects and the settlement of environmental
matters. 

 Estimated environmental cash payments (on an undiscounted and unescalated basis) total $186 million in 2013, $225
million in 2014, $124 million in 2015, $107 million in 2016, $110 million in 2017 and $1.7 billion thereafter. The amounts and timing of these estimated payments could change as a result of changes in regulatory requirements, changes in scope and
timing of remediation activities, the settlement of environmental matters and as actual spending occurs. 
 FCX was required to record
FMC’s environmental obligations at fair value on the acquisition date in accordance with business combination accounting guidance. Significant adjustments to these obligations may occur in the future. At December 31, 2012, FCX’s
environmental obligations totaled $2.4 billion on an undiscounted and unescalated basis (compared with $1.2 billion recorded on the balance sheet, which included environmental obligations assumed in the FMC acquisition at fair value). FCX estimates
it is reasonably possible that these obligations could range between $2.1 billion and $2.7 billion on an undiscounted and unescalated basis. 

FCX believes that there may be potential claims for recovery from third parties, including the U.S. government and other PRPs. These potential recoveries
are not recognized unless realization is considered probable. 
 At December 31, 2012, the most significant environmental obligations were
associated with the Pinal Creek site in Arizona; the Newtown Creek site in New York City; historical smelter sites principally located in Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania; and uranium mining sites in the western U.S. The
recorded environmental obligations for these sites totaled $1.0 billion at December 31, 2012. A discussion of these sites follows. 

Pinal Creek. The Pinal Creek site was listed under the Arizona Department of Environmental Quality’s (ADEQ) Water Quality Assurance Revolving
Fund program in 1989 for contamination in the shallow alluvial aquifers within the Pinal Creek drainage near Miami, Arizona. Since that time, environmental remediation was performed by members of the Pinal Creek Group (PCG), consisting of FMC Miami,
Inc. (Miami), a wholly owned subsidiary of FMC, and two other companies. In 1998, the District Court approved a Consent Decree between the PCG members and the state of Arizona resolving all matters related to an enforcement action contemplated by
the state of Arizona against the PCG members with respect to groundwater contamination. The Consent Decree committed the PCG members to complete the remediation work outlined in the Consent Decree, and that work continues at this time and is
expected to continue for many years in the future. Miami also was a party to litigation entitled Pinal Creek Group, et al. v. Newmont Mining Corporation, et al., United States District Court, District of Arizona, Case No. CIV 91-1764 PHX DAE
(LOA), filed on May 1, 1991. Pursuant to a settlement 







 
in 2010, Miami paid $40 million to certain members of the PCG to settle the allocation of previously incurred costs, and agreed to take full responsibility for future groundwater remediation at
the Pinal Creek site, with limited exceptions. The settlement did not result in a change to the obligation, which was estimated at fair value when assumed in the FMC acquisition. During 2011, the obligation was increased by $31 million to reflect
changes in remediation capping designs that incorporate best practices for side slope regrading and cap thickness. 
 Newtown Creek. From
the 1930s until 1964, Phelps Dodge Refining Corporation (PDRC), a subsidiary of FMC, operated a smelter, and from the 1930s until 1984, it operated a refinery on the banks of Newtown Creek (the creek), which is a 3.5-mile-long waterway that forms
part of the boundary between Brooklyn and Queens in New York City. Heavy industrialization along the banks of the creek and discharges from the City of New York’s sewer system over more than a century resulted in significant environmental
contamination of the waterway. The New York Attorney General previously notified several companies, including PDRC, about possible obligations to clean up contaminated sediments in the creek. In March and April 2010, EPA notified PDRC and five
others that EPA considers them to be PRPs under CERCLA. The notified parties began working with EPA to identify other PRPs, and EPA proposed that the notified parties perform a Remedial Investigation/Feasibility Study (RI/FS) at their expense and
reimburse EPA for its oversight costs. EPA is not expected to propose a remedy until after a RI/FS is completed, which is expected to take several years. On September 29, 2010, EPA designated the creek as a Superfund site. Effective
July 18, 2011, PDRC and five other parties entered an Administrative Order on Consent (AOC) to perform a RI/FS to assess the nature and extent of environmental contamination in the creek and identify potential remedial options. The
parties’ RI/FS work under the AOC and their identification of other PRPs are ongoing. FCX’s financial obligation for this matter was estimated at fair value when it was assumed in the FMC acquisition and is included in FCX’s aggregate
environmental obligations. The actual costs of fulfilling this remedial obligation and the allocation of costs among PRPs are uncertain and subject to change based on the results of the RI/FS, the remediation remedy ultimately selected by EPA and
related allocation determinations. Depending on the overall cost and the portion allocated to PDRC, that share could be material to FCX. 

Historical Smelter Sites. FMC and its predecessors at various times owned or operated copper and zinc smelters in several states, including
Arizona, Kansas, New Jersey, Oklahoma and Pennsylvania. For some of these smelter sites, certain FCX subsidiaries have been advised by EPA or state agencies that they may be liable for costs of investigating and, if appropriate, remediating
environmental conditions associated with the smelters. At other sites, certain FCX subsidiaries have entered into state voluntary remediation programs to investigate and, if appropriate, remediate site conditions associated with the smelters. The
historical smelter sites are in various stages of assessment and remediation. The two most significant environmental obligations for historical smelter sites relate to Blackwell, Oklahoma, and Bisbee, Arizona. Adjustments to the environmental
obligations for historical smelter sites, which principally were estimated at fair value when assumed in the FMC acquisition, totaled a reduction of $47 







 
million in 2012, primarily because of changes in estimated timing of obligations, and an increase of $36 million in 2011, primarily at the Blackwell, Oklahoma, site (refer to discussion below).

 Blackwell. From 1918 to 1974, Blackwell Zinc Company, Inc. (BZC), an indirect subsidiary of FCX, owned and operated a zinc smelter in
Blackwell, Oklahoma. In 1974, the smelter was demolished and the property deeded to the Blackwell Industrial Authority. Pursuant to an administrative order with the state of Oklahoma, BZC undertook remedial actions in Blackwell in 1996 and 1997,
including sampling the nearby residential and commercial properties, and removing soils on properties that were found to have metal concentrations above state-established cleanup standards. From 1997 to 2003, BZC investigated the nature and extent
of groundwater contamination potentially attributable to the former smelter and evaluated options for remedying such contamination. In 2003, the state of Oklahoma adopted a cleanup plan requiring the installation of a groundwater extraction and
treatment system and the closure of domestic groundwater wells within the groundwater plume area. BZC completed the construction of a groundwater extraction and treatment system, with system startup and initial discharge of treated water occurring
in October 2010. 
 Between 2007 through 2012, FCX, on behalf of BZC, completed a voluntary soil remediation program by inviting property owners
in and around Blackwell to have soil at their properties sampled for the presence of smelter-related contaminants, and offering to remediate properties whose soils were found to have metal concentrations above state-established cleanup standards. As
part of this program, FCX sampled soils on approximately 90 percent of the residential properties in Blackwell and remediated soils on about 600 properties. All of these soil sampling and remediation activities were coordinated with, and supervised
by, the state of Oklahoma. 
 On May 23, 2012, the Board of Commissioners of Kay County, Oklahoma, filed suit in Oklahoma District Court
against FCX and several affiliates, including BZC, entitled Board of Commissioners of the County of Kay, Oklahoma v. Freeport-McMoRan Copper & Gold Inc., et al., United States District Court, Western District of Oklahoma, Case
No. 5:12-cv-00601-C. On May 25, 2012, the case was removed to the United States District Court for the Western District of Oklahoma, and trial is set for October 2013. The suit alleges BZC permitted large quantities of smelter waste to be
used as road building and fill material throughout Kay County over a period of decades and seeks unspecified financial assistance for removing and covering much of the material, and unspecified damages for the alleged public nuisance created by the
presence of the material. FCX has asserted a counter claim against Kay County for contribution under CERCLA. Separate from the litigation, in fourth-quarter 2012, BZC entered into a Consent Agreement and Final Order with the Oklahoma Department of
Environmental Quality and Kay County to conduct an assessment of smelter material present on Kay County’s roads, bridges and associated rights-of-way. Sampling is expected to be completed in 2013. 

Bisbee. From the 1880s until 1975, FMC and certain predecessor and subsidiary entities operated a copper mine near Bisbee, Arizona. A series of
smelters operated in Bisbee 







 
from approximately 1879 through 1908. In 2000, FMC entered the Bisbee area into the Arizona Voluntary Remediation Program (VRP) administered by ADEQ. In 2008, FMC expanded the VRP project to
include other communities near Bisbee and commenced a voluntary community outreach program inviting property owners to have soils at their properties sampled for the presence of smelter and mine-related metals. For property owners whose soils are
found to have metal concentrations above ADEQ established cleanup standards, FMC has offered to remove the impacted soils and replace them with clean soils. For those property owners who requested sampling, approximately 40 percent require some
level of cleanup. At December 31, 2012, approximately 60 percent of owners who agreed to have soil cleanup on their properties was completed. 
 Uranium Mining Sites. During a period between 1940 and the early 1970s, certain FMC predecessor entities were involved in uranium exploration and mining in the western U.S. Similar exploration and
mining activities by other companies have caused environmental impacts that have warranted remediation, and EPA and local authorities are currently evaluating the need for significant cleanup activities in the region. To date, FMC has undertaken
remediation at a limited number of sites associated with these predecessor entities. An initiative to gather additional information about sites in the region is ongoing, and information gathered under this initiative was submitted to EPA Region 9
during the second and third quarters of 2008 and the fourth quarter of 2009 in response to an information request by EPA regarding uranium mining activities on Navajo Nation properties. FCX utilized the results of FMC’s remediation experience,
in combination with historical and updated information to initially estimate the fair value of uranium-related liabilities assumed in the FMC acquisition. 
 Asset Retirement Obligations (AROs). FCX’s ARO cost estimates are reflected on a third-party cost basis and comply with FCX’s legal obligation to retire tangible, long-lived assets. A
summary of changes in FCX’s AROs for the year ended December 31, 2012 (in millions) follows:

	(a)	Revisions to cash flow estimates were primarily related to updated closure plans that included revised cost estimates and accelerated timing of certain closure
activities. 

 ARO costs may increase or decrease significantly in the future as a result of changes in regulations, changes in
engineering designs and technology, permit modifications or updates, changes in mine plans, inflation or other factors and as actual reclamation spending occurs. ARO activities and expenditures generally are made over an extended period of time
commencing near the end of the mine life; however, certain reclamation activities may be accelerated if legally required or if determined to be economically beneficial. 







 Legal requirements in New Mexico, Arizona and Colorado require financial assurance to be provided for the
estimated costs of reclamation and closure, including groundwater quality protection programs. FCX has satisfied financial assurance requirements by using a variety of mechanisms, such as performance guarantees, financial capability demonstrations,
trust funds, surety bonds, letters of credit and collateral. The applicable regulations specify financial strength tests that are designed to confirm a company’s or guarantor’s financial capability to fund estimated reclamation and closure
costs. The amount of financial assurance FCX is required to provide will vary with changes in laws, regulations and reclamation and closure requirements, and cost estimates. At December 31, 2012, FCX’s financial assurance obligations
associated with these closure and reclamation costs totaled $946 million, of which approximately $582 million was in the form of guarantees issued by FCX and financial capability demonstrations. At December 31, 2012, FCX had trust assets
totaling $161 million, which are legally restricted to fund a portion of its AROs for properties in New Mexico as required by New Mexico regulatory authorities. 
 New Mexico Environmental and Reclamation Programs. FCX’s New Mexico operations are regulated under the New Mexico Water Quality Act and regulations adopted under that act by the Water Quality
Control Commission (WQCC). The New Mexico Environment Department (NMED) has required each of these operations to submit closure plans for NMED’s approval. The closure plans must include measures to assure meeting groundwater quality standards
following the closure of discharging facilities and to abate any groundwater or surface water contamination. In March 2009, the Tyrone operation appealed the WQCC Final Order, dated February 4, 2009, regarding location of the “places of
withdrawal of water,” a legal criterion used to determine where groundwater quality standards must be met at FCX’s New Mexico mining sites. In December 2010, Tyrone entered into a settlement agreement with NMED that calls for a stay of the
appeal while NMED and the WQCC complete several administrative actions, including renewal of Tyrone’s closure permit consistent with the terms of the settlement, review and approval of a groundwater abatement plan and adoption of alternative
abatement standards, and adoption of new groundwater discharge permit rules for copper mines. If the administrative actions are concluded consistent with the terms of the settlement agreement within the period of the stay, then Tyrone will move to
dismiss the appeal. In December 2012, Tyrone and NMED agreed to extend the period to conclude the administrative actions through December 31, 2013. The Court of Appeals also extended the stay for another year. Finalized closure plan
requirements, including those resulting from the actions to be taken under the settlement agreement, could result in increases in the Tyrone, Chino and Cobre closure costs. 
 FCX’s New Mexico operations also are subject to regulation under the 1993 New Mexico Mining Act (the Mining Act) and the related rules that are administered by the Mining and Minerals Division (MMD)
of the New Mexico Energy, Minerals and Natural Resources Department. Under the Mining Act, mines are required to obtain approval of 







 
plans describing the reclamation to be performed following cessation of mining operations. At December 31, 2012, FCX had accrued reclamation and closure costs of $476 million for its New
Mexico operations. As stated above, additional accruals may be required based on the state’s review of FCX’s updated closure plans and any resulting permit conditions, and the amount of those accruals could be material. 

Arizona Environmental and Reclamation Programs. FCX’s Arizona properties are subject to regulatory oversight in several areas. ADEQ has
adopted regulations for its aquifer protection permit (APP) program that require permits for, among other things, certain facilities, activities and structures used for mining, concentrating and smelting and require compliance with aquifer water
quality standards at an applicable point of compliance well or location. The APP program also may require mitigation and discharge reduction or elimination of some discharges. 
 An application for an APP requires a description of a closure strategy that will meet applicable groundwater protection requirements following cessation of operations and an estimate of the cost to
implement the closure strategy. An APP may specify closure requirements, which may include post-closure monitoring and maintenance. A more detailed closure plan must be submitted within 90 days after a permitted entity notifies ADEQ of its intent to
cease operations. A permit applicant must demonstrate its financial ability to meet the closure costs estimated in the APP. 
 Portions of
Arizona mining facilities that operated after January 1, 1986, also are subject to the Arizona Mined Land Reclamation Act (AMLRA). AMLRA requires reclamation to achieve stability and safety consistent with post-mining land use objectives
specified in a reclamation plan. Reclamation plans must be approved by the State Mine Inspector and must include an estimate of the cost to perform the reclamation measures specified in the plan. FCX will continue to evaluate options for future
reclamation and closure activities at its operating and non-operating sites, which are likely to result in adjustments to FCX’s ARO liabilities. At December 31, 2012, FCX had accrued reclamation and closure costs of $240 million for its
Arizona operations. 
 Colorado Reclamation Programs. FCX’s Colorado operations are regulated by the Colorado Mined Land Reclamation
Act (Reclamation Act) and regulations promulgated thereunder. Under the Reclamation Act, mines are required to obtain approval of reclamation plans describing the reclamation of lands affected by mining operations to be performed during mining or
upon cessation of mining operations. As of December 31, 2012, FCX had accrued reclamation and closure costs of $47 million for its Colorado operations. 
 Chilean Reclamation and Closure Programs. In July 2011, the Chilean senate passed legislation regulating mine closure, which establishes new requirements for closure plans and became effective in
November 2012. FCX’s Chilean operations will be required to update closure plans and provide financial assurance for these obligations. FCX cannot predict at this time the cost of these closure plans or the levels or forms of financial
assurance that may be required. Revised closure plans for the Chilean mine sites are due in November 2014. At December 31, 2012, FCX had accrued reclamation and closure costs of $54 million for its Chilean operations. 







 Peruvian Reclamation and Closure Programs. Cerro Verde is subject to regulation under the Mine
Closure Law administered by the Peruvian Ministry of Energy and Mines. Under the closure regulations, mines must submit a closure plan that includes the reclamation methods, closure cost estimates, methods of control and verification, closure and
post-closure plans and financial assurance. The updated closure plan for the Cerro Verde mine expansion must be submitted to the Peruvian regulatory authorities in December 2014. At December 31, 2012, Cerro Verde had accrued reclamation and
closure costs of $89 million. 
 PT Freeport Indonesia Reclamation and Closure Programs. The ultimate amount of reclamation and closure
costs to be incurred at PT Freeport Indonesia’s operations will be determined based on applicable laws and regulations and PT Freeport Indonesia’s assessment of appropriate remedial activities in the circumstances, after consultation with
governmental authorities, affected local residents and other affected parties and cannot currently be projected with precision. Estimates of the ultimate reclamation and closure costs PT Freeport Indonesia will incur in the future involve complex
issues requiring integrated assessments over a period of many years and are subject to revision over time as more complete studies are performed. Some reclamation costs will be incurred during mining activities, while most closure costs and the
remaining reclamation costs will be incurred at the end of mining activities, which are currently estimated to continue for approximately 30 years. At December 31, 2012, PT Freeport Indonesia had accrued reclamation and closure costs of $195
million and a long-term receivable for Rio Tinto’s share of the obligation of $18 million (included in long-term receivables). 
 In 1996,
PT Freeport Indonesia began contributing to a cash fund ($16 million balance at December 31, 2012) designed to accumulate at least $100 million (including interest) by the end of its Indonesia mining activities. PT Freeport Indonesia plans to
use this fund, including accrued interest, to pay mine closure and reclamation costs. Any costs in excess of the $100 million fund would be funded by operational cash flow or other sources. 
 In December 2010, the President of Indonesia issued a regulation regarding mine reclamation and closure, which requires a company to provide a mine closure guarantee in the form of a time deposit placed
in a state-owned bank in Indonesia. In accordance with its Contract of Work, PT Freeport Indonesia is working with the Department of Energy and Mineral Resources to review these requirements, including discussion of other options for the mine
closure guarantee. In December 2009, PT Freeport Indonesia submitted its revised mine closure plan to the Department of Energy and Mineral Resources for review and has addressed comments received during the course of this review process. 








 Litigation. 
 Asbestos Claims. Since approximately 1990, FMC and various subsidiaries have been named as defendants in a large number of lawsuits that claim personal injury either from exposure to asbestos
allegedly contained in electrical wire products produced or marketed many years ago or from asbestos contained in buildings and facilities located at properties owned or operated by FMC affiliates, or from alleged asbestos in talc products. Many of
these suits involve a large number of codefendants. Based on litigation results to date and facts currently known, FCX believes there is a reasonable possibility that losses may have been incurred related to these matters; however, FCX also believes
that the amounts of any such losses, individually or in the aggregate, are not material to its consolidated financial statements. There can be no assurance, however, that future developments will not alter this conclusion. 

Yonkers Site. From 1932 until 1984, FMC owned and operated a cable manufacturing facility on the Hudson River in Yonkers, New York. FMC sold that
operation in 1984, and it was subsequently sold to BICC Cables Corporation (BICC). BICC closed the facility in 1996. In 2005, Blackacre Partners OPS, LLC (Blackacre) began environmental cleanup work at the site using funding provided by FMC and
BICC. One Point Street, Inc. (OPS), a real estate developer, has current title to the site. 
 On September 9, 2011, OPS filed a complaint
in the United States District Court for the Southern District of New York, which it amended on March 1, 2012. The amended complaint alleged that FMC, BICC and Blackacre failed to timely and diligently complete remediation of the site in breach
of alleged obligations under CERCLA and New York Environmental Conservation Law, and under the contractual agreements among the parties. In fourth-quarter 2012, this matter was settled, and OPS will be completing the limited remaining cleanup work
at the site using funds provided by FMC and BICC. 
 Columbian Chemicals Company (Columbian) Claims. Columbian, formerly a subsidiary of
FMC, has notified FCX of various indemnification claims arising out of the 2005 agreement pursuant to which Columbian was sold. The principal outstanding claims relate to (1) multiple mass tort suits pending against Columbian in West Virginia
state court for alleged personal injury and property damage resulting from exposure to carbon black (the Carbon Black claims) and (2) an investigation being conducted by EPA of potential Clean Air Act violations during the period Columbian was
owned by FMC (the Clean Air Act matter). In April 2012, Columbian filed suit in New York state court (Columbian Chemicals Company and Columbian Chemicals Acquisition LLC v. Freeport-McMoRan Corporation f/k/a Phelps Dodge Corporation, County
of New York, Supreme Court of the State of New York, Index No. 600999/2010), that alleged, among other things, that the Carbon Black claims are the responsibility of FMC, and are not subject to the aggregate cap under the 2005 agreement pursuant to
which Columbian was sold. In July 2012, FCX and Columbian reached a settlement pursuant to which the litigation was dismissed with prejudice and all outstanding disputes regarding the extent of FCX’s indemnity obligations to Columbian were
fully resolved. Under the terms of the settlement, FCX’s remaining possible exposure is to indemnify Columbian for incurred losses related only to the Carbon Black claims and the Clean Air Act matter. The cap, net








 
of amounts reserved and paid, totaled $122 million at December 31, 2012. FMC cannot estimate Columbian’s exposure, if any, for the Carbon Black claims or the Clean Air Act matter.

 Shareholder Litigation. Thirteen derivative actions challenging the PXP merger and/or the MMR merger were filed on behalf of FCX by
purported FCX stockholders. Ten were filed in the Court of Chancery of the State of Delaware and three were filed in the Superior Court of the State of Arizona, County of Maricopa. On January 25, 2013, the Delaware Court of Chancery
consolidated the Delaware actions into a single action, In Re Freeport-McMoRan Copper & Gold Inc. Derivative Litigation, No. 8145-VCN. On January 17, 2013, the Arizona Superior Court consolidated two of the Arizona actions
into In Re Freeport-McMoRan Derivative Litigation, No. CV2012-018351. A third Arizona complaint, Harris v. Adkerson et al., No. CV2013-004163, filed on January 16, 2013, has not yet been consolidated. The actions name some or all of the
following as defendants: the directors and certain officers of FCX, two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions allege, among other things, that the FCX directors breached
their fiduciary duties to FCX stockholders because they, among other things, pursued their own interests at the expense of stockholders in approving the PXP and MMR mergers. The complaints also allege that some or all of the following parties aided
and abetted the wrongful acts allegedly committed by the directors and certain officers of FCX: two FCX subsidiaries, PXP and certain of its directors, and MMR and certain of its directors and officers. The actions seek as relief, among other
things, an injunction barring or rescinding both the PXP merger and the MMR merger and requiring submission of the proposed PXP merger and MMR merger to a vote of FCX stockholders, damages, and attorneys’ fees and costs. 

Three putative class actions challenging the PXP merger were filed on behalf of PXP stockholders in the Court of Chancery of the State of Delaware. On
January 15, 2013, the Court of Chancery consolidated the actions into a single action, In Re Plains Exploration & Production Company Stockholder Litigation, No. 8090-VCN. The action names as defendants PXP, the directors of
PXP, FCX, and an FCX subsidiary. The action alleges that PXP’s directors breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with
respect to the merger, and that FCX and an FCX subsidiary aided and abetted the breach of fiduciary duties by PXP’s directors. The action seeks as relief an injunction barring or rescinding the PXP merger, damages, and attorneys’ fees and
costs. 
 In addition, ten putative class actions challenging the MMR merger were filed on behalf of MMR stockholders. Nine were filed in the
Court of Chancery of the State of Delaware. On January 25, 2012, the Court of Chancery consolidated the actions into a single action, In Re McMoRan Exploration Co. Stockholder Litigation, No. 8132-VCN. One action was also filed in
the Civil District Court for the Parish of Orleans of the State of Louisiana: Langley v. Moffett et al., No. 2012-11904, filed December 19, 2012. Each of the actions names some or all of the following as defendants, in addition to
MMR and its directors: FCX, subsidiaries of FCX, and PXP. The actions allege that MMR’s directors 







 
breached their fiduciary duties because they, among other things, pursued their own interests at the expense of stockholders and failed to maximize stockholder value with respect to the merger,
and that PXP, FCX, or both, aided and abetted the breach of fiduciary duty by MMR’s directors. The Delaware action also asserts claims derivatively on behalf of MMR. The actions seek, among other things, injunctive relief barring or rescinding
the MMR merger, damages, and attorneys’ fees and costs. 
 FCX intends to vigorously defend itself in these matters. 

Tax Matters. Cerro Verde Tax Proceedings. SUNAT, the Peruvian national tax authority, has assessed mining royalties on materials processed
by the Cerro Verde concentrator that commenced operations in late 2006. These assessments cover the period October 2006 to December 2007 and the years 2008 and 2009. SUNAT has issued rulings denying Cerro Verde’s protest of the assessments.
Cerro Verde has appealed these decisions and currently has three cases pending before the Peruvian Tax Court. Cerro Verde is challenging these royalties because it believes its stability agreement provides an exemption for all minerals extracted
from its mining concession, irrespective of the method used for processing those minerals. Although FCX believes its interpretation of the stability agreement is correct, if Cerro Verde is ultimately found responsible for these assessments, it will
also be liable for interest, which accrues at rates that range from approximately 7 to 18 percent based on the year accrued and the currency in which the amounts would be payable. At December 31, 2012, the aggregate amount of the assessments,
including interest and penalties, totaled $218 million. SUNAT may continue to assess mining royalties annually until this matter is resolved by the Peruvian Tax Tribunal. 
 Cerro Verde is also challenging various income and value-added tax assessments from SUNAT covering the years 2002 through 2008 and has cases pending before the Peruvian Tax Court. At December 31,
2012, the approximate amount of these assessments, including interest and penalties, totaled $180 million. 
 Indonesia Tax Matters. The
Indonesian tax authorities issued assessments for various audit exceptions on PT Freeport Indonesia’s tax returns as follows (in millions):

 PT Freeport Indonesia has filed objections to the assessments because it believes it has properly paid its taxes. During
first-quarter 2012, PT Freeport Indonesia’s objections to the assessments related to 2005 were substantially all rejected by the Indonesian tax authorities and, in May 2012, appeals were filed with the Indonesian Tax Court. As of








 
December 31, 2012, PT Freeport Indonesia has paid $182 million (of which $148 million is included in long-term receivables) for the disputed tax assessments related to 2005, 2006 and 2007.
PT Freeport Indonesia is working with the Indonesian tax authorities to resolve these matters and expects to receive additional assessments from the Indonesian tax authorities for their audit of its 2008 tax return. 

In December 2009, PT Freeport Indonesia was notified by the Large Taxpayer’s Office of the Government of Indonesia of its view that PT Freeport
Indonesia is obligated to pay value added taxes on certain goods imported after the year 2000. The amount of such taxes and related penalties under this view would be significant. PT Freeport Indonesia believes that, pursuant to the terms of its
Contract of Work, it is only required to pay value added taxes on these types of goods imported after December 30, 2009. PT Freeport Indonesia has not received a formal assessment and is working with the applicable government authorities to
resolve this matter. 
 Letters of Credit, Bank Guarantees and Surety Bonds. Letters of credit and bank guarantees totaled $98 million at
December 31, 2012, primarily for reclamation and environmental obligations, workers’ compensation insurance programs, tax and customs obligations, and other commercial obligations. In addition, FCX had surety bonds totaling $159 million at
December 31, 2012, associated with reclamation and closure ($137 million – see discussion above), self-insurance bonds primarily for workers’ compensation ($18 million) and other bonds ($4 million). 

Insurance. FCX purchases a variety of insurance products to mitigate potential losses. The various insurance products typically have specified
deductible amounts or self-insured retentions and policy limits. FCX generally is self-insured for U.S. workers’ compensation, but purchases excess insurance up to statutory limits. An actuarial analysis is performed twice a year for various
FCX casualty programs, including workers’ compensation, to estimate required insurance reserves. Insurance reserves totaled $52 million at December 31, 2012, which consisted of a current portion of $8 million (included in accounts payable
and accrued liabilities) and a long-term portion of $44 million (included in other liabilities). 
 FCX maintains property damage and business
interruption insurance related to its operations. FCX and its insurers entered into an insurance settlement agreement in December 2012. The insurers agreed to pay an aggregate of $63 million, including $4 million for PT Freeport Indonesia’s
joint venture partner’s interest, for the settlement of the insurance claim for business interruption and property damage relating to the 2011 incidents affecting PT Freeport Indonesia’s concentrate pipelines. As a result of the
settlement, FCX recorded a gain of $59 million ($31 million to net income attributable to FCX common stockholders).
