 - 6 - 

 
presumed to equal the percentages associated with Level III of the pricing grid set forth above until the date of delivery of such Quarter-End Borrowing Base Certificate, at which time the rate
will be adjusted based upon the Average Undrawn Availability reflected on such Quarter-End Borrowing Base Certificate. Notwithstanding anything to the contrary contained herein, no downward adjustment in any Applicable Margin for each type of
Advance (other than the Term Loan) shall be made on any Adjustment Date on which any Event of Default shall have occurred and be continuing. Notwithstanding anything to the contrary contained herein, immediately and automatically upon the occurrence
of any Event of Default, the Applicable Margin for each type of Advance (other than the Term Loan) shall increase to and equal the percentages associated with Level III of the pricing grid set forth above and shall continue at such highest
Applicable Margin until the date (if any) on which such Event of Default shall be waived in accordance with the provisions of this Agreement, at which time the rate will be adjusted based upon the Average Undrawn Availability reflected on the most
recently delivered Quarter-End Borrowing Base Certificate delivered by Borrowers to Agent pursuant to Section 9.9. Any increase in interest rates and/or other fees payable by Borrowers under this Agreement and the Other Documents pursuant to
the provisions of the foregoing sentence shall be in addition to and independent of any increase in such interest rates and/or other fees resulting from the occurrence of any Event of Default (including, if applicable, any Event of Default arising
from a breach of Sections 9.9 hereof) and/or the effectiveness of the Default Rate provisions of Section 3.1 hereof or the default fee rate provisions of Section 3.2 hereof. 

If, as a result of any restatement of, or other adjustment to, the Quarter-End Borrowing Base Certificate or
for any other reason, Agent determines that (a) the Average Undrawn Availability as previously calculated as of any applicable date for any applicable period was inaccurate, and (b) a proper calculation of the Average Undrawn Availability
for any such period would have resulted in different pricing for such period, then (i) if the proper calculation of the Average Undrawn Availability would have resulted in a higher interest rate and/or fees (as applicable) for such period,
automatically and immediately without the necessity of any demand or notice by Agent or any other affirmative act of any party, the interest accrued on the applicable outstanding Advances and/or the amount of the fees accruing for such period under
the provisions of this Agreement and the Other Documents shall be deemed to be retroactively increased by, and Borrowers shall be obligated to immediately pay to Agent for the ratable benefit of Lenders an amount equal to the excess of the amount of
interest and fees that should have been paid for such period over 

  
 - 7 - 

 
the amount of interest and fees actually paid for such period; and (ii) if the proper calculation of the Average Undrawn Availability would have resulted in a lower interest rate and/or fees
(as applicable) for such period, then the interest accrued on the applicable outstanding Advances and the amount of the fees accruing for such period under the provisions of this Agreement and the Other Documents shall be deemed to remain unchanged,
and Agent and Lenders shall have no obligation to repay interest or fees to the Borrowers; provided, that, if as a result of any restatement or other event or other determination by Agent a proper calculation of the Average Undrawn Availability
would have resulted in a higher interest rate and/or fees (as applicable) for one or more periods and a lower interest rate and/or fees (as applicable) for one or more other periods (due to the shifting of income or expenses from one period to
another period or any other reason), then the amount payable by Borrowers pursuant to clause (i) above shall be based upon the excess, if any, of the amount of interest and fees that should have been paid for all applicable periods over the
amounts of interest and fees actually paid for such periods.

mean any Lender that: (a) has failed, within two (2) Business Days of the date required to be funded or paid, to (i) fund any portion of its Revolving Commitment Percentage or Term Loan Commitment, as applicable, of Advances,

the case of clause (i) above, such Lender notifies Agent in writing that such failure is the result of such Lender’s good faith determination that a condition precedent to funding (specifically identified and including a particular Default
or Event of Default, if any) has not been satisfied; (b) has notified Borrowers or Agent in writing, or has made a public statement to the effect, that it does not intend or expect to comply with any of its funding obligations under this

any) to funding a loan under this Agreement cannot be satisfied) or generally under other agreements in which it commits to extend credit; (c) has failed, within two (2) Business Days after request by Agent, acting in good faith, to

 Exhibit 10.1 

Amendment No. 1 to 

Settlement and Termination Agreement 

May 16, 2016 
 This Amendment No.
1 (“Amendment”) to that certain Settlement and Termination Agreement dated as of May 10, 2016, by and among Freeport-McMoRan Inc. (“FCX”), Freeport-McMoRan Oil & Gas LLC and Noble Drilling (U.S.) LLC (“Noble”) (the
“Agreement”), is made by and among the parties thereto. Unless otherwise defined in this Amendment, capitalized terms used herein have the meanings assigned to those terms in the Agreement or the Distribution Agreement (defined below) as
the context requires. 
 1. The term “Start Date” as defined in Section 2(a)(i) of the Agreement is hereby amended to mean the
period beginning on May 16, 2016 (the “Start Date”). 
 2. Section 2 of the Agreement shall be amended by replacing paragraph (2)
with the following: 
 “Each Stock Issuance shall comply with the following requirements: (i) one or more agents or underwriters shall
have agreed on the date of such Stock Issuance to accept such Shares for resale by Noble prior to such Stock Issuance (in the case of any resale pursuant to the Distribution Agreement, an Agent (as defined therein) shall have delivered a Transaction
Acceptance or a Terms Agreement prior to or concurrently with such Stock Issuance), (ii) (A) if such Stock Issuance occurs before 9:00 a.m. Eastern Time on the date of such Stock Issuance, no such Stock Issuance will exceed 20% of the simple average
trading volume of FCX Stock for the five consecutive trading days preceding such Stock Issuance or (B) if such Stock Issuance occurs at or after 9:00 a.m. Eastern Time on the date of such Stock Issuance, no such Stock Issuance will exceed 10%
of the simple average trading volume of FCX Stock for the five consecutive trading days immediately preceding such Stock Issuance, (iii) FCX shall notify Noble of any such Stock Issuance prior to 9:00 a.m., Eastern Time on the date of such Stock
Issuance or, if the notice occurs later than 9:00 a.m. on the date of any Stock Issuance, the calculation of the volume-weighted average price described in the next sentence shall begin one-half hour after the actual time of such notice to Noble,
but in no event shall notice of any Stock Issuance be later than 1:00 p.m., Eastern Time on any date, and (iv) no Stock Issuance shall occur when there is a Suspension Notice in effect (as defined below). The per share volume-weighted average price
for any Exchange Business Day (as defined in the Distribution Agreement) on which there is a Stock Issuance shall be calculated in accordance with the definition of VWAP in that certain Distribution Agreement to be dated on or about May 16, 2016, by
and among FCX, Noble and the Agents named therein (the “Distribution Agreement”). FCX Stock issued to Noble will be valued at the greater of (x) the VWAP for such Share and (y) the floor price per Share previously agreed to among the
parties to the Distribution Agreement (the “Floor Price”). In addition, the FCX Stock issued to Noble will be (a) pursuant to FCX’s effective shelf registration statement, (b) delivered to Noble through the facilities of The
Depository Trust Company on the first Exchange Business Day (as defined in the Distribution Agreement) after the Stock Issuance, and (c) fully paid and non-assessable and free and clear of all liens and encumbrances.” 

 3. Section 2 of the Agreement shall be amended by adding at the end of paragraph (2): 

“Notwithstanding the foregoing, for any Purchase Date (as defined in the Distribution Agreement) with respect to which FCX issued a
notice of Stock Issuance, if at any time on such date the price per Share on the New York Stock Exchange is less than the Floor Price, then Noble will have the right but not the obligation, solely at its option, to reject all or a portion of such
Stock Issuance solely to the extent of any Shares that are unsold under the Distribution Agreement by delivering a notice to FCX no later than the opening of trading on the Exchange Business Day (as defined in the Distribution Agreement) immediately
following such date.” 
 4. Section 2 of the Agreement shall be amended by adding the following at the end of paragraph (a): 

“(iii) FCX shall, on June 22, 2016, pay by federal funds wire transfer to the account of Noble specified in writing by the Noble, an
amount equal to 1.0% of the aggregate Gross Sales Price of the Shares sold under the Distribution Agreement.” 
 Except as expressly
set forth in this Amendment, all of the terms and conditions, and all other provisions of the Agreement are hereby ratified and confirmed and shall remain in full force and effect.

This Amendment may be executed in multiple counterparts, each of which shall be deemed an original but all of which shall constitute one and
the same instrument.
