 Exhibit 10.1 
 AGREEMENT 
 AGREEMENT (this “Agreement”) dated as of November 30, 2007 by and between Windsor
Permian LLC, a Delaware limited liability company (“Windsor”), and Gulfport Energy Corporation, a Delaware corporation (“Gulfport”). 
 RECITALS 
 1. Windsor has entered into that certain Purchase and Sale Agreement dated November 28, 2007
(the “Purchase Agreement”) with Ambrose Energy I, Ltd., a Texas limited partnership, and each of the other entities party thereto (collective, the “Sellers”). 
 2. Pursuant to the Purchase Agreement, Sellers have agreed to sell and Windsor has agreed to purchase the Assets (as defined in the Purchase Agreement)
for the Purchase Price (as defined in the Purchase Agreement, and including for purposes of this Agreement, all pre- and post-closing adjustments to the Purchase Price). 
 3. Windsor desires to grant to Gulfport and Gulfport desires to obtain from Windsor an option to acquire a direct, undivided 50% interest in the Assets for 50% of the Purchase Price on the terms set forth herein.

 In consideration of the mutual undertakings herein contained and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, and intending to be legally bound, the parties agree as follows: 
 Section 1. Option. 

(a) Windsor hereby grants Gulfport an irrevocable, unconditional option (the “Option”) to purchase a direct, undivided 50% interest in the
Assets and a proportionate assignment of Windsor’s rights under the Purchase Agreement and in connection therewith to assume of 50% interest in the Assumed Obligations (as defined in the Purchase Agreement) in each case as provided in and
subject to the terms and conditions of the Purchase Agreement (collectively, the “Option Assets”). 
 (b) The Option may be
exercised by Gulfport in whole, but not in part, at any time after the execution of this Agreement and prior to midnight on December 12, 2007 (the “Expiration Time”). In the event that Gulfport wishes to exercise the Option, it shall
deliver written notice to Windsor of such exercise and such notice shall specify the closing date (the “Closing Date”) for the closing on the exercise of the Option (the “Closing”). 
 (c) Prior to the Expiration Time and, if the Option is exercised by Gulfport, thereafter, Windsor shall not amend, modify, waive or terminate all or any
provision of the Purchase Agreement, without the prior written consent of Gulfport. 

 Section 2. Option Price; Closing. 
 (a) The price to be paid by Gulfport to Windsor for the Option Assets (the “Option Price”) shall be 50% of the Purchase Price, plus 50% of all
third-party costs and expenses incurred by Windsor in connection with the contemplated purchase of the Assets, including without limitation, all due diligence, legal and other costs and expenses net of 50% of the third-party costs incurred by
Gulfport for the benefit of the transaction (collectively, “Costs”) and the assumption of liability for 50% of the Assumed Obligations. Gulfport hereby pays to an account designated by Windsor, and Windsor acknowledges receipt of, the
amount of $8,500,000 (the “Deposit”). In the event that Gulfport exercises the Option, on the Closing Date Gulfport shall pay the balance of the Option Price to such account as may be specified in writing by Windsor. If Gulfport does not
exercise the Option on or before the Expiration Time, then it shall forfeit the Deposit in full; provided, however, if Gulfport does exercise the Option and the Assets are not acquired and the full or some lesser amount of the Earnest Money Deposit
(as defined in the Purchase Agreement) is returned by Sellers under the terms of the Purchase Agreement, then the Deposit (or the proportionate amount of the Deposit if the Earnest Money Deposit is not returned in full), less in each case 50% of all
Costs, shall be repaid to Gulfport, without interest, within two (2) business days after the receipt by Windsor of such Earnest Money Deposit. 
 (b) At the Closing, Windsor and Gulfport shall deliver such assignments, certificates, affidavits and other documents as shall be necessary and appropriate in the determination of Windsor and Gulfport to reflect Gulfport’s acquisition
of the Option Assets and a proportionate assignment of Windsor’s rights under the Purchase Agreement.

 Section 5. Miscellaneous. 
 (a) Entire Agreement. This Agreement, together with the Purchase Agreement and the other transaction documents and all schedules, exhibits, annexes or other attachments hereto or thereto, and the certificates,
documents, instruments and writings that are delivered pursuant hereto or thereto, constitutes the entire agreement and understanding of the parties in respect of the subject matter hereof and supersedes all prior understandings, agreements or
representations by or among the parties, written or oral, to the extent they relate in any way to the subject matter hereof. 
 (b)
Assignment; Binding Effect. No party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other party, and any such assignment by a party without the prior written
approval of the other party will be deemed invalid and not binding on such other party. All of the terms, agreements, covenants, representations, warranties and conditions of this Agreement are binding upon, inure to the benefit of and are
enforceable by, the parties and their respective successors and permitted assigns. 
 (c) Notices. All notices, requests and other
communications provided for or permitted to be given under this Agreement must be in writing and must be given by personal delivery, by certified or registered United States mail (postage prepaid, return receipt requested), by a nationally
recognized overnight delivery service for next day delivery, or by facsimile transmission, to the intended recipient at the address set forth for the recipient on the signature page (or to such other address as any Party may give in a notice given
in accordance with the provisions hereof). All notices, requests or other communications will be effective and deemed given only as follows: (i) if given by personal delivery, upon such personal delivery, (ii) if sent by certified or
registered mail, on the fifth business day after being deposited in the United States mail, (iii) if sent for next day delivery by overnight delivery service, on the date of delivery as confirmed by written confirmation of delivery or
(iv) if sent by facsimile, upon the transmitter’s confirmation of receipt of such facsimile transmission, except that if such confirmation is received after 5:00 p.m. (in the recipient’s time zone) on a business day, or is received on
a day that is not a business day, then such notice, request or communication will not be deemed effective or given until the next succeeding business day. Notices, requests and other communications sent in any other manner, including by electronic
mail, will not be effective. 
 (d) Specific Performance; Remedies. Each party acknowledges and agrees that the other party would be damaged
irreparably if any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached. Accordingly, the parties will be entitled to an injunction or injunctions to prevent breaches of the provisions of
this Agreement and to enforce specifically this Agreement and its provisions in any action or proceeding instituted in the federal court sitting in Oklahoma County, Oklahoma having jurisdiction over the parties and the matter, in addition to any
other remedy to which they may be entitled, at law or in equity. Except as expressly provided herein, the rights, obligations and remedies created by this Agreement are cumulative and in addition to any other rights, obligations or remedies
otherwise available at law or in equity. Nothing herein will be considered an election of remedies. 
  

 4 

 (e) Headings. The article and section headings contained in this Agreement are inserted for convenience
only and will not affect in any way the meaning or interpretation of this Agreement. 
 (f) Governing Law. This Agreement will be governed by
and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law principles. 
 (g) Amendment;
Extensions; Waivers. No amendment, modification, waiver, replacement, termination or cancellation of any provision of this Agreement will be valid unless the same is in writing and signed by Windsor and Gulfport and specifically states that it is
intended to amend, modify, terminate or cancel this Agreement or waive a right hereunder. Each waiver of a right hereunder does not extend beyond the specific event or circumstance giving rise to the right. No waiver by any party of any default,
misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights
arising because of any prior or subsequent such occurrence. Neither the failure nor any delay on the part of any party to exercise any right or remedy under this Agreement will operate as a waiver thereof, nor does any single or partial exercise of
any right or remedy preclude any other or further exercise of the same or of any other right or remedy. 
 (h) Severability. The provisions
of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided, however, that if any provision of this
Agreement, as applied to any party or to any circumstance, is judicially determined not to be enforceable in accordance with its terms, the parties agree that the court judicially making such determination may modify the provision in a manner
consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its modified form, such provision will then be enforceable and will be enforced. 
 (i) Expenses. Except as otherwise expressly provided in this Agreement, each party will bear its own costs and expenses incurred in connection with the
preparation, execution and performance of this Agreement and the Transactions, including all fees and expenses of agents, representatives, financial advisors, legal counsel and accountants. 
 (j) Counterparts; Effectiveness. This Agreement may be executed in one or more counterparts, each of which will be deemed an original but all of which
together will constitute one and the same instrument. This Agreement will become effective when one or more counterparts have been signed by each party and delivered to the other parties. 
 (k) Construction. This Agreement has been freely and fairly negotiated among the parties. If an ambiguity or question of intent or interpretation arises,
this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any Party because of the authorship of any provision of this Agreement. The words “include,”

  

 5 

 
“includes,” and “including” will be deemed to be followed by “without limitation.” The word “person” includes
individuals, entities and Governmental Bodies. Pronouns in masculine, feminine and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the
context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision
unless expressly so limited. The parties intend that each representation, warranty and covenant contained herein will have independent significance. If any party has breached any representation, warranty or covenant contained herein in any respect,
the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the party has not breached will not detract from or mitigate the fact that the party
is in breach of the first representation, warranty or covenant. 
 (l) Confidentiality. Gulfport acknowledges that it has been and will be
provided Confidential Information, as defined in the Purchase Agreement, and agrees to abide by the provisions of the Purchase Agreement regarding Confidential Information.

 Reverse of Security 
 This Security is one of a duly authorized series of Securities of the Company designated as Buffered Return Enhanced Notes Linked to the S&P 500® Index
Due November 29, 2011 (herein called the “Securities”). The Company may, without the consent of the holders of the Securities, create and issue additional securities ranking equally with the Securities and otherwise similar in
all respects so that such additional securities shall be consolidated and form a single series with the Securities; provided that no additional securities can be issued if an Event of Default has occurred with respect to the Securities. This series
of Securities is one of an indefinite number of series of debt securities of the Company, issued and to be issued under an indenture, dated as of September 1, 1987, as amended (herein called the “Indenture”), duly executed and
delivered by the Company and Citibank, N.A., as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby
made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities. 
 The Payment at Maturity at the request of the Trustee shall be determined by the Calculation Agent pursuant to the Calculation Agency Agreement. The Trustee shall fully rely on the determination by the Calculation
Agent of the Payment at Maturity and shall have no duty to make any such determination. The Calculation Agent will provide written notice to the Trustee at its New York office, on which notice the Trustee may conclusively rely, of the Payment at
Maturity on or prior to 11:00 a.m. on the Business Day preceding the Maturity Date. 
 All calculations with respect to the Index Starting
Level, the Index Ending Level, the Index Return or any Index Closing Level will be rounded to the nearest one hundred-thousandth, with five one-millionths rounded upward (e.g., .876545 would be rounded to .87655); all dollar amounts related
to determination of the payment per $1,000 principal amount Security on the Maturity Date, if any, will be rounded to the nearest ten-thousandth, with five one hundred-thousandths rounded upward (e.g., .76545 would be rounded up to .7655);
and all dollar amounts paid on the aggregate principal amount of Securities per Holder will be rounded to the nearest cent, with one-half cent rounded upward. 
 This Security is not subject to any sinking fund. 
 If an Event of Default with respect to the Securities
shall occur and be continuing, the amounts payable on all of the Securities may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under
the Indenture will be equal to the Payment at Maturity calculated as though the date of acceleration were the Maturity Date and the third Business Day immediately preceding the date of acceleration were the Valuation Date. If the maturity of the
Securities is accelerated because of an Event of Default, the Company shall, or shall cause the Calculation Agent to, provide written notice to the Trustee at its New York office, on which notice the Trustee may conclusively rely, and to The
Depository Trust Company of the cash amount due with respect to the Securities as promptly as possible and in no event later than two Business Days after the date of acceleration. 

 The Indenture contains provisions permitting the Company and the Trustee, with the consent of the
holders of not less than 66 2/3% in aggregate principal amount of each series of Securities at the time
Outstanding to be affected (each series voting as a class), evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to, or changing in any manner or eliminating any of the provisions of the Indenture or of
any supplemental indenture or modifying in any manner the rights of the holders of the Securities of all such series; provided, however, that no such supplemental indenture shall, among other things, (i) change the fixed
maturity of any Security, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, if any, or reduce any premium payable on redemption, or make the principal thereof, or premium, if any, or
interest thereon, if any, payable in any coin or currency other than that hereinabove provided, without the consent of the holder of each Security so affected, or (ii) change the place of payment on any Security, or impair the right to
institute suit for payment on any Security, or reduce the aforesaid percentage of Securities, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of each Security so affected. It is
also provided in the Indenture that, prior to any declaration accelerating the maturity of any series of Securities, the holders of a majority in aggregate principal amount of the Securities of such series Outstanding may on behalf of the holders of
all the Securities of such series waive any past default or Event of Default under the Indenture with respect to such series and its consequences, except a default in the payment of interest, if any, or the principal of, or premium, if any, on any
of the Securities of such series, or in the payment of any sinking fund installment or analogous obligation with respect to Securities of such series. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon
such Holder and upon all future holders and owners of this Security and any Securities which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the Payment at Maturity with respect to this Security. 
 The Securities are
issuable in denominations of $1,000 and any whole multiples of $1,000. 
 The Company, the Trustee, and any agent of the Company or of the
Trustee may deem and treat the registered holder (the “Holder”) hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for
the purpose of receiving payment hereof, or on account hereof, and for all other purposes and neither the Company nor the Trustee nor any agent of the Company or of the Trustee shall be affected by any notice to the contrary. All such payments made
to or upon the order of such registered holder shall, to the extent of the sum or sums paid, effectually satisfy and discharge liability for moneys payable on this Security. 
 No recourse for the payment of the principal of, premium, if any, or interest on this Security, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Security, or because of the creation of any indebtedness represented 

  

 2 

 
thereby, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
 As provided in the Indenture and
subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office or agency in a Place of Payment for
this Security, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and
thereupon one or more new Securities of this series or of like tenor and of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Company intends to treat, and by purchasing this Security, the Holder agrees to treat, for all tax purposes, this Security as a cash-settled
financial contract, rather than as a debt instrument. 
 THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK. 
 Definitions 
 Set forth below are definitions of the terms used in this Security. 
 “Buffer Amount”
shall equal 15%. 
 “Business Day”, notwithstanding any provision in the Indenture, shall mean any day that is not a
Saturday or Sunday and that is not a day on which banking institutions in the City of New York are authorized or obligated by law to close. 
 “Calculation Agency Agreement” shall mean the Calculation Agency Agreement, dated as of December 21, 2006 between the Company and the Calculation Agent, as amended from time to time, or any successor calculation agency
agreement. 
 “Calculation Agent” shall mean the person that has entered into an agreement with the Company providing for,
among other things, the determination of the Payment at Maturity, which term shall, unless the context otherwise requires, include its successors and assigns. The initial Calculation Agent shall be Lehman Brothers Inc. 
 “Closing Price” of a security, on any particular day, means the last reported sales price for that security on the Relevant Exchange at
the scheduled weekday closing time of the regular trading session of the Relevant Exchange. If, however, the security is not listed or traded on a bulletin board, then the Closing Price of the security will be determined using the average execution
price per share that an affiliate of the Company pays or receives upon the purchase or sale of the security used to hedge the Company’s obligations under the Securities. 
  

 3 

 “Company” shall have the meaning set forth on the face of this Security. 
 “Holder” shall have the meaning set forth on the reverse of this Security. 
 “Indenture” shall have the meaning set forth on the reverse of this Security. 
 “Index” shall mean the S&P 500® Index, as calculated, published and
disseminated by S&P. 
 “Index Closing Level”, as determined by the Calculation Agent, shall mean, with respect to any
Trading Day, the closing level of the Index or the Successor Index, as the case may be, at the regular official weekday close of the principal trading session of the Relevant Exchange or market for the Index or the Successor Index, as the case may
be, on such day, or as determined by the Calculation Agent pursuant to the Calculation Agency Agreement as described below under “Discontinuation of the Index; Alteration of Method of Calculation.” 
 “Index Ending Level” shall equal the Index Closing Level on the Valuation Date. 
 “Index Return”, as calculated by the Calculation Agent, is calculated as follows: 
  

	
	Index Ending Level — Index Starting Level
	Index Starting Level

 “Index Sponsor” with respect to the Index shall be S&P. The Calculation
Agent, in its sole discretion, may select a new Index Sponsor as described under “Discontinuation of the Index; Alteration of Method of Calculation.” 
 “Index Starting Level” shall equal 1,407.22. 
 “Market Disruption Event”,
with respect to the Index or any Successor Index shall mean any of the following events has occurred on any day as determined by the Calculation Agent: 
 (1) a suspension, absence or material limitation of trading of stocks then constituting 20% or more of the level of the Index (or the relevant Successor Index) on the Relevant Exchanges for such securities at any time
during the one hour period preceding the close of the principal trading session on such Relevant Exchange; 
 (2) a breakdown or failure in
the price and trade reporting systems of any Relevant Exchange as a result of which the reported trading prices for stocks then constituting 20% or more of the level of the Index (or the relevant Successor Index) at any time during the one hour
period preceding the close of the principal trading session on such Relevant Exchange are materially inaccurate; 
 (3) a suspension,
absence or material limitation of trading on any major securities exchange for trading in futures or options contracts or exchange traded 

  

 4 

 
funds related to the Index (or the relevant Successor Index) at any time during the one hour period preceding the close of the principal trading session on
such exchange; or 
 (4) a decision to permanently discontinue trading in the relevant futures or options contracts or exchange traded
funds. 
 For the purpose of determining whether a Market Disruption Event exists at any time, if trading in a security included in the
Index is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the level of the Index shall be based on a comparison of: 
 (1) the portion of the level of the Index attributable to that security relative to 
 (2) the overall level of the Index, 
 in
each case immediately before that suspension or limitation. 
 For purposes of determining whether a Market Disruption Event has occurred:

 (1) a limitation on the hours or number of days of trading will not constitute a Market Disruption Event if it results from an announced
change in the regular business hours of the Relevant Exchange or market; 
 (2) limitations pursuant to the rules of any Relevant Exchange
similar to NYSE Rule 80B (or any applicable rule or regulation enacted or promulgated by any other self-regulatory organization or any government agency of scope similar to NYSE Rule 80B as determined by the Calculation Agent in its sole discretion)
on trading during significant market fluctuations will constitute a suspension, absence or material limitation of trading; 
 (3) a
suspension of trading in futures or options contracts on the Index by the primary securities market trading in such contracts by reason of (i) a price change exceeding limits set by such exchange or market, (ii) an imbalance of orders
relating to such contracts, or (iii) a disparity in bid and ask quotes relating to such contracts, will, in each such case, constitute a suspension, absence or material limitation of trading in futures or options contracts related to the Index;
and 
 (4) a suspension, absence or material limitation of trading on any Relevant Exchange or on the primary market on which futures or
options contracts related to the Index are traded will not include any time when such market is itself closed for trading under ordinary circumstances. 
 “Maturity Date” shall mean November 29, 2011, unless that day is not a Business Day, in which case the amount equal to the Payment at Maturity that would otherwise be due on 

  

 5 

 
the scheduled Maturity Date will instead be due on the next succeeding Business Day following such scheduled Maturity Date, with the same effect as if paid
on the scheduled Maturity Date; provided that if due to a non-Trading Day or a Market Disruption Event, the Valuation Date is postponed so that it falls less than three Business Days prior to the scheduled Maturity Date, the Maturity Date will be
the third Business Day following the Valuation Date, as postponed. 
 “Participation Rate” shall equal 111.20%. 

“Payment at Maturity”, as calculated by the Calculation Agent for each $1,000 principal amount Security, shall equal: 
  

	 	•	 	 If the Index Return is positive, 

 $1,000 + ($1,000 × Index Return × Participation Rate) 
  

	 	•	 	 If the Index Return is negative or zero, but its absolute value does not exceed the Buffer Amount, $1,000. 

  

	 	•	 	 If the Index Return is negative, and its absolute value exceeds the Buffer Amount, $1,000 + [$1,000 × (Index Return + Buffer Amount)].

 “Place of Payment” shall mean the place or places where the Payment at Maturity on the Securities is
payable. 
 “Pricing Date” shall mean November 26, 2007. 
 “Relevant Exchange” for any security (or any combination thereof) then included in the Index or any Successor Index, shall mean, the
primary exchange, quotation system (which includes bulletin board services) or other market of trading for such security. 
 “S&P” shall mean Standard & Poor’s a division of The McGraw-Hill Companies, Inc. 
 “Securities” shall have the meaning set forth on the reverse of this Security. 
 “Successor
Index” shall have the meaning specified under “Discontinuation of the Index; Alteration of Method of Calculation”. 
 “Trading Day” means a day, as determined by the Calculation Agent, on which trading is generally conducted (i) on the Relevant Exchanges for securities included in the Index (or the relevant Successor Index) and
(ii) the exchanges on which futures or options contracts related to the Index (or the relevant Successor Index) are traded, other than a day on which trading on such Relevant Exchange or exchange on which such securities, futures or options
contracts are traded is scheduled to close prior to its scheduled weekday closing time. 
 “Trustee” shall have the meaning
set forth on the reverse of this Security. 
 “Valuation Date” shall mean November 23, 2011; provided,
however, that if the scheduled Valuation Date is not a Trading Day or if there is a Market Disruption Event on such day, 

  

 6 

 
the Valuation Date shall be postponed to the immediately succeeding Trading Day during which no Market Disruption Event shall have occurred or shall be
continuing; provided, however, that the Index Ending Level for the Valuation Date shall not be determined on a date later than the eighth scheduled Trading Day after the originally scheduled Valuation Date, and if such day is not a
Trading Day, or if there is a Market Disruption Event on such date, the Calculation Agent shall determine the Index Ending Level for the Valuation Date on such date in accordance with the formula for and method of calculating the Index Ending Level
last in effect prior to commencement of the Market Disruption Event (or prior to the non-Trading Day), using the Closing Price (or, if trading in the relevant securities has been materially suspended or materially limited, the Calculation
Agent’s good faith estimate of the Closing Price that would have prevailed but for such suspension or limitation or non-Trading Day) on such eighth scheduled Trading Day of each security most recently constituting the Index. 
 All terms used but not defined in this Security are used herein as defined in the Calculation Agency Agreement or the Indenture. 
 Calculation Agent 
 The Calculation Agent will
determine, among other things, the Index Closing Level on each Trading Day, the Index Ending Level, the Index Return and the Payment at Maturity. In addition, the Calculation Agent will determine whether there has been a Market Disruption Event or a
discontinuation of the Index, and whether there has been a material change in the method of calculation of the Index. All calculations, determinations or adjustments made by the Calculation Agent will be at the sole discretion of the Calculation
Agent and will, in the absence of manifest error, be conclusive for all purposes and binding on Holders and on the Company. The Company may appoint a different Calculation Agent from time to time after the date of the original issue of the
Securities without the Holders’ consent and without notifying Holders. 
 Discontinuation of the Index; Alteration of Method of Calculation

 If the Index Sponsor discontinues publication of the Index and the Index Sponsor or another entity publishes a successor or
substitute index that the Calculation Agent determines, in its sole discretion, to be comparable to the discontinued Index (a “Successor Index”), then any Index Closing Level will be determined by reference to the level of such Successor
Index at the close of trading on the Relevant Exchange or market for the Successor Index on any Trading Day. Upon any selection by the Calculation Agent of a Successor Index, the Calculation Agent will cause written notice thereof to be promptly
furnished to the Trustee, to the Company and to the Holders. 
 If the Index Sponsor discontinues publication of the Index, and such
discontinuation is continuing on any Trading Day, and the Calculation Agent determines, in its sole discretion, that no Successor Index is available at such time, or if the Calculation Agent has previously selected a Successor Index and publication
of such Successor Index is discontinued, and such discontinuation is continuing on any Trading Day, or if the Index Sponsor (or the publisher of any Successor Index) fails to calculate and publish an Index Closing Level for the 

  

 7 

 
Index (or any Successor Index) on any date when it would ordinarily do so in accordance with its customary practice, then the Calculation Agent will
determine the Index Closing Level for such Trading Day or such date. The Index Closing Level will be computed by the Calculation Agent in accordance with the formula for and method of calculating the Index or Successor Index, as applicable, last in
effect on the date prior to such discontinuation or failure to calculate or publish an Index Closing Level for the Index or Successor Index, as applicable, using the Closing Price (or, if trading in the relevant securities has been materially
suspended or materially limited, its good faith estimate of the Closing Price that would have prevailed but for such suspension or limitation) at the close of the principal trading session on such date of each security most recently included in the
Index or Successor Index, as applicable. 
 If at any time the method of calculating the Index or a Successor Index, or the level thereof,
is changed in a material respect, or if the Index or a Successor Index is in any other way modified so that the Index or such Successor Index does not, in the opinion of the Calculation Agent, fairly represent the level of the Index or such
Successor Index in the absence of such changes or modifications, then the Calculation Agent will, at the close of business in New York City on each date on which the Index Closing Level is to be determined, make such calculations and adjustments as,
in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a level of a stock index comparable to the Index or such Successor Index, as the case may be, as if such changes or modifications were not made, and the
Calculation Agent will calculate the Index Closing Level with reference to the Index or such Successor Index, as adjusted. Accordingly, if the method of calculating the Index or a Successor Index is modified so that the level of the Index or such
Successor Index is a fraction of what it would have been if there had been no such modification (e.g., due to a split in the Index), then the Calculation Agent will adjust its calculation of the Index or such Successor Index in order to
arrive at a level of the Index or such Successor Index as if there had been no such modification (e.g., as if such split had not occurred).
