This master confirmation (this “Master Confirmation”), dated as of April 6, 2015 is intended to set forth certain terms and provisions of certain Transactions (each, a “Transaction”) entered into from time to time between Goldman, Sachs & Co. (“Dealer”) and Duke Energy Corporation (“Counterparty”). This Master Confirmation, taken alone, is neither a commitment by either party to enter into any Transaction nor evidence of a Transaction. The additional terms of any particular Transaction shall be set forth in a Supplemental Confirmation in the form of Schedule A hereto (a “Supplemental Confirmation”), which shall reference this Master Confirmation and supplement, form a part of, and be subject to this Master Confirmation. This Master Confirmation and each Supplemental Confirmation together shall constitute a “Confirmation” as referred to in the Agreement specified below.

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc., are incorporated into this Master Confirmation. This Master Confirmation and each Supplemental Confirmation evidence a complete binding agreement between Counterparty and Dealer as to the subject matter and terms of each Transaction to which this Master Confirmation and such Supplemental Confirmation relate and shall supersede all prior or contemporaneous written or oral communications with respect thereto.

This Master Confirmation and each Supplemental Confirmation supplement, form a part of, and are subject to an agreement in the form of the 1992 ISDA Master Agreement (Multicurrency-Cross Border) (the “Agreement”) as if Dealer and Counterparty had executed the Agreement on the date of this Master Confirmation (but without any Schedule except for (i) the election of Loss and Second Method, New York law (without reference to its choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law) as the governing law and US Dollars (“USD”) as the Termination Currency, (ii) the election that subparagraph (ii) of Section 2(c) will not apply to the Transactions, (iii) the replacement of the word “third” in the last line of Section 5(a)(i) with the word “second”, (iv) the election that the “Cross Default” provisions of Section 5(a)(vi) shall apply to Dealer, with a “Threshold Amount” of three percent (3%) of Dealer’s shareholders’ equity, and to Counterparty, with a “Threshold Amount” of USD 150 million (provided that, in each case, (a) the text “, or becoming capable at such time of being declared,” shall be deleted from Section 5(a)(vi)(1) and (b) the following provision shall be added to the end of Section 5(a)(vi): “but a default under clause (2) above shall not constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature, (y) funds were available to enable the party to make the payment when due and (z) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay”) and (v) that Credit Support Provider means, in relation to Dealer, The Goldman Sachs Group, Inc.).

The Transactions shall be the sole Transactions under the Agreement. If there exists any ISDA Master Agreement between Dealer and Counterparty or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Dealer and Counterparty are parties, the Transactions shall not be considered Transactions under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

All provisions contained or incorporated by reference in the Agreement shall govern this Master Confirmation and each Supplemental Confirmation except as expressly modified herein or in the related Supplemental Confirmation.

If, in relation to any Transaction to which this Master Confirmation and a Supplemental Confirmation relate, there is any inconsistency between the Agreement, this Master Confirmation, any Supplemental Confirmation and the Equity Definitions, the following will prevail for purposes of such Transaction in the order of precedence indicated: (i) such Supplemental Confirmation; (ii) this Master Confirmation; (iii) the Equity Definitions; and (iv) the Agreement.

1.Each Transaction constitutes a Share Forward Transaction for the purposes of the Equity Definitions. Set forth below are the terms and conditions that, together with the terms and conditions set forth in the Supplemental Confirmation relating to any Transaction, shall govern such Transaction.

General Terms:

Prepayment\Variable

Valuation:

Calculation Agent will include only those trades that are reported during the period of time during which Counterparty could purchase its own shares under Rule 10b-18(b)(2) and are effected pursuant to the conditions of Rule 10b-18(b)(3), each under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (such trades, “Rule 10b-18 eligible transactions”).

Forward Price

Section 6.3(d) of the Equity Definitions is hereby amended by deleting the remainder of the provision following the term “Scheduled Closing Time” in the fourth line thereof.

Notwithstanding anything to the contrary in the Equity Definitions, to the extent that a Disrupted Day occurs (i) on a Scheduled Trading Day scheduled to be a Calculation Date in the Calculation Period, the Calculation Agent may, in its good faith and commercially reasonable discretion, postpone the Scheduled Termination Date to the next Calculation Date, or (ii) on a Scheduled Trading Day scheduled to be a Calculation Date in the Settlement Valuation Period, the Calculation Agent may extend the Settlement Valuation Period by up to one Calculation Date for each such Disrupted Day. If any such Disrupted Day is a Disrupted Day because of a Market Disruption Event (or a deemed Market Disruption Event as provided herein), the Calculation Agent shall determine whether (i) such Disrupted Day is a Disrupted Day in full, in which case the VWAP Price for such Disrupted Day shall not be included for purposes of determining the Forward Price or the Settlement Price, as the case may be, or (ii) such Disrupted Day is a Disrupted Day only in part, in which case the VWAP Price for such Disrupted Day shall be determined by the Calculation Agent based on Rule 10b-18 eligible transactions in the Shares on such Disrupted Day taking into account the nature and duration of the relevant Market Disruption Event, and the weighting of the VWAP Price for the relevant Calculation Dates during the Calculation Period or the Settlement Valuation Period, as the case may be, shall be adjusted in a commercially reasonable manner by the Calculation Agent for purposes of determining the Forward Price or the Settlement Price, as the case may be, with such adjustments based on, among other factors, the duration of any Market Disruption Event and the volume, historical trading patterns and price of the Shares. Any Exchange Business Day on which, as of the date hereof, the Exchange is scheduled to close prior to its normal close of trading shall be deemed not to be an Exchange Business Day; if a closure of the Exchange prior to its normal close of trading on any Exchange Business Day is scheduled following the date hereof, then such Exchange Business Day shall be deemed to be a Disrupted Day in full.

If a Disrupted Day occurs on a Scheduled Trading Day scheduled to be a Calculation Date during the Calculation Period or the Settlement Valuation Period, as the case may be, and each of the five immediately following scheduled Calculation Dates is a Disrupted Day, then the Calculation Agent, in its good faith and commercially reasonable discretion, may deem such fifth scheduled Calculation Date to be an Exchange Business Day that is not a Disrupted Day and determine the VWAP Price for such fifth scheduled Calculation Date using its good faith estimate of the value of the Shares on such fifth scheduled Calculation Date based on the volume, historical trading patterns and price of the Shares and such other factors as it deems appropriate.

Settlement Terms:    

Number of Shares

It shall constitute an additional Potential Adjustment Event if the Scheduled Termination Date for any Transaction is postponed pursuant to “Valuation Disruption” above, in which case the Calculation Agent may, in its commercially reasonable discretion, adjust any relevant terms of any such Transaction as necessary to account for the economic effect on such Transaction of such postponement; provided that the Calculation Agent shall not change the designation of any Calculation Date.

3.Additional Mutual Representations, Warranties and Covenants of Each Party. In addition to the representations, warranties and covenants in the Agreement, each party represents, warrants and covenants to the other party that:

(a)    Eligible Contract Participant. It is an “eligible contract participant”, as defined in the U.S. Commodity Exchange Act (as amended), and is entering into each Transaction hereunder as principal (and not as agent or in any other capacity, fiduciary or otherwise) and not for the benefit of any third party.

(b)    Accredited Investor. Each party acknowledges that the offer and sale of each Transaction to it is intended to be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), by virtue of Section 4(a)(2) thereof. Accordingly, each party represents and warrants to the other that (i) it has the financial ability to bear the economic risk of its investment in each Transaction and is able to bear a total loss of its investment, (ii) it is an “accredited investor” as that term is defined under Regulation D under the Securities Act and (iii) the disposition of each Transaction is restricted under this Master Confirmation, the Securities Act and state securities laws.

(c)    Guarantee of The Goldman Sachs Group, Inc.  The obligations of Dealer in respect of each Transaction hereunder will be guaranteed by The Goldman Sachs Group, Inc. pursuant to (i) the General Guarantee Agreement, dated January 30, 2006, made by The Goldman Sachs Group, Inc. relating to certain obligations of Dealer (available as Exhibit 10.45 to The Goldman Sachs Group, Inc. Annual Report on Form 10-K for the fiscal year ended November 25, 2005), or (ii) any replacement or successor guarantee, which may be in the form of a general guarantee or a guarantee that specifically references the Transactions (in each case, the “Guarantee”).  For the avoidance of doubt, the obligations of Dealer in respect of each Transaction hereunder shall be recourse payment obligations as such term is used in the Guarantee and for all other purposes. The parties agree and acknowledge that the Guarantee shall not be a Credit Support Document hereunder.

4.Additional Representations, Warranties and Covenants of Counterparty. In addition to the representations, warranties and covenants in the Agreement, Counterparty represents, warrants and covenants to Dealer that:

(a)    The purchase or writing of each Transaction and the transactions contemplated hereby will not violate Rule 13e-1 or Rule 13e-4 under the Exchange Act.

(b)    It is not entering into any Transaction (i) on the basis of, and is not aware of, any material non-public information with respect to the Shares, (ii) in anticipation of, in connection with, or to facilitate, a distribution of its securities, a self tender offer or a third-party tender offer or (iii) to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares).

(c)    Each Transaction is being entered into pursuant to a publicly disclosed Share buy-back program and its Board of Directors has approved the use of derivatives to effect the Share buy-back program.

(d)    Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that neither Dealer nor any of its affiliates is making any representations or warranties or taking any position or expressing any view with respect to the treatment of any Transaction under any accounting standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging - Contracts in Entity’s Own Equity.

(e)    As of (i) the date hereof and (ii) the Trade Date for each Transaction hereunder, Counterparty is in compliance with its reporting obligations under the Exchange Act and its most recent Annual Report on Form 10-K, together with all reports subsequently filed or furnished by it pursuant to the Exchange Act and all public statements by it, taken together and as amended and supplemented to the date of this representation, do not, as of their respective dates, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f)    Counterparty shall report each Transaction as required under the Exchange Act and the rules and regulations thereunder.

(g)    The Shares are not, and Counterparty will not cause the Shares to be, subject to a “restricted period” (as defined in Regulation M promulgated under the Exchange Act) at any time during any Regulation M Period (as defined below) for any Transaction unless Counterparty has provided written notice to Dealer of such restricted period not later than the Scheduled Trading Day immediately preceding the first day of such “restricted period”; Counterparty acknowledges that any such notice may cause a Disrupted Day to occur pursuant to Section 5 below; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 6 below; “Regulation M Period” means, for any Transaction, (i) the Relevant Period (as defined below) and (ii) the Settlement Valuation Period, if any, for such Transaction. “Relevant Period” means, for any Transaction, the period commencing on the Trade Date for such Transaction and ending on the earlier of (i) the Scheduled Termination Date and (ii) the last Additional Relevant Day (as specified in the related Supplemental Confirmation) for such Transaction, or such earlier day as elected by Dealer and communicated to Counterparty on such day (or, if later, the First Acceleration Date without regard to any acceleration thereof pursuant to “Special Provisions for Acquisition Transaction Announcements” below).

(h)    As of the Trade Date, the Prepayment Date, the Initial Share Delivery Date and the Settlement Date for each Transaction, Counterparty is not “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and Counterparty would be able to purchase a number of Shares with a value equal to the Prepayment Amount in compliance with the laws of the jurisdiction of Counterparty’s incorporation.

(i)    Counterparty is not and, after giving effect to any Transaction, will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

(j)    Counterparty has not entered into and will not enter into agreements similar to the Transactions described herein where the relevant calculation or valuation dates in any initial hedge period, calculation period, relevant period or settlement valuation period (each however defined) in such other transaction will coincide at any

time (including as a result of extensions in such initial hedge period, calculation period, relevant period or settlement valuation period as provided in the relevant agreements) with the Calculation Dates in any Relevant Period or, if applicable, any Settlement Valuation Period under this Master Confirmation. In the event that any relevant calculation or valuation dates in any initial hedge period, relevant period, calculation period or settlement valuation period in any other similar transaction coincides with any Calculation Dates in any Relevant Period or, if applicable, Settlement Valuation Period under this Master Confirmation as a result of any postponement of the Scheduled Termination Date or extension of the Settlement Valuation Period pursuant to “Valuation Disruption” above, Counterparty shall promptly amend such transaction to avoid any such overlap.

4A.    Additional Representations, Warranties and Covenants of Dealer. In addition to the representations, warranties and covenants in the Agreement, Dealer represents, warrants and covenants to Counterparty that Dealer shall use commercially reasonable efforts, during the Calculation Period and any Settlement Valuation Period for each Transaction, to make all purchases of Shares in connection with such Transaction in a manner that would comply with the limitations set forth in clauses (b)(1), (b)(2), (b)(3) and (b)(4) and (c) of Rule 10b-18 under the Exchange Act (“Rule 10b-18”), as if such rule were applicable to such purchases and taking into account any applicable Securities and Exchange Commission no-action letters as appropriate, and subject to any delays between the execution and reporting of a trade of the Shares on the Exchange and other circumstances beyond Dealer’s control; provided that, during a Calculation Period, the foregoing agreement shall not apply to purchases made to dynamically hedge for Dealer’s own account or the account of its affiliate(s) the optionality arising under a Transaction (including, for the avoidance of doubt, timing optionality); and provided further that, without limiting the generality of the first sentence of this Section 4A, Dealer shall not be responsible for any failure to comply with Rule 10b-18(b)(3) to the extent any transaction that was executed (or deemed to be executed) by or on behalf of Counterparty or an “affiliated purchaser” (as defined under Rule 10b-18) pursuant to a separate agreement is not deemed to be an “independent bid” or an “independent transaction” for purposes of Rule 10b-18(b)(3).

5.Regulatory Disruption. In the event that Dealer concludes, in its reasonable discretion, that it is appropriate with respect to any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer but so long as such requirements, policies or procedures are generally applicable in similar circumstances and not arbitrarily or capriciously applied), for it to refrain from or decrease any market activity on any Scheduled Trading Day or Days during the Calculation Period or, if applicable, the Settlement Valuation Period, Dealer may by written notice to Counterparty elect to deem that a Market Disruption Event has occurred and will be continuing on such Scheduled Trading Day or Days.

6.10b5-1 Plan. Counterparty represents, warrants and covenants to Dealer that:

(a)    Counterparty is entering into this Master Confirmation and each Transaction hereunder in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b5-1 under the Exchange Act (“Rule 10b5-1”) or any other antifraud or anti-manipulation provisions of the federal or applicable state securities laws and that it has not entered into or altered and will not enter into or alter any corresponding or hedging transaction or position with respect to the Shares. Counterparty acknowledges that it is the intent of the parties that each Transaction entered into under this Master Confirmation comply with the requirements of paragraphs (c)(1)(i)(A) and (B) of Rule 10b5-1 and each Transaction entered into under this Master Confirmation shall be interpreted to comply with the requirements of Rule 10b5-1(c).

(b)    Counterparty will not seek to control or influence Dealer’s decision to make any “purchases or sales” (within the meaning of Rule 10b5-1(c)(1)(i)(B)(3)) under any Transaction entered into under this Master Confirmation, including, without limitation, Dealer’s decision to enter into any hedging transactions. Counterparty represents and warrants that it has consulted with its own advisors as to the legal aspects of its adoption and implementation of this Master Confirmation and each Supplemental Confirmation under Rule 10b5-1.

(c)    Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of this Master Confirmation or the relevant Supplemental Confirmation must be effected in accordance with the requirements for the amendment or termination of a “plan” as defined in Rule 10b5-1(c). Without limiting the generality of the foregoing, any such amendment, modification, waiver or termination shall be made in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Exchange Act, and no such

amendment, modification or waiver shall be made at any time at which Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information regarding Counterparty or the Shares.

7.Counterparty Purchases. Counterparty (or any “affiliated purchaser” as defined in Rule 10b-18) shall not, without the prior written consent of Dealer, directly or indirectly purchase any Shares (including by means of a derivative instrument), listed contracts on the Shares or securities that are convertible into, or exchangeable or exercisable for Shares (including, without limitation, any Rule 10b-18 purchases of blocks (as defined in Rule 10b-18)) on any Calculation Date during any Relevant Period or, if applicable, Settlement Valuation Period, except through Dealer. However, the foregoing shall not (a) limit Counterparty’s ability, pursuant to its employee incentive plan or dividend reinvestment program, to re-acquire Shares from employees in connection with such plan or program, (b) limit Counterparty’s ability to withhold Shares to cover tax liabilities associated with such a plan, (c) prohibit any purchases effected by or for an issuer “plan” by an “agent independent of the issuer” (each as defined in Rule 10b-18), (d) otherwise restrict Counterparty’s or any of its affiliates’ ability to repurchase Shares under privately negotiated, off exchange transactions with any of its employees, officers, directors, affiliates or any third party that are not expected to result in market transactions or (e) limit Counterparty’s ability to grant stock and options to “affiliated purchasers” (as defined in Rule 10b-18) or the ability of such affiliated purchasers to acquire such stock or options in connection with Counterparty’s compensation policies for directors, officers and employees or any agreements with respect to the compensation of directors, officers or employees of any entities that are acquisition targets of Counterparty, and in connection with any such purchase under (a) through (e) above, Counterparty will be deemed to represent to Dealer that such purchase does not constitute a “Rule 10b-18 purchase” (as defined in Rule 10b‑18).

8.Special Provisions for Merger Transactions. Notwithstanding anything to the contrary herein or in the Equity Definitions:

(a)    Counterparty agrees that it:

(i)    will not during the period commencing on the Trade Date through the end of the Relevant Period or, if applicable, the Settlement Valuation Period for any Transaction make, or permit to be made (if within its control), any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction or potential Merger Transaction (a “Public Announcement”) unless such Public Announcement is made prior to the opening or after the close of the regular trading session on the Exchange for the Shares;

(ii)    shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) notify Dealer following any such Public Announcement that such Public Announcement has been made; and

(iii)    shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) provide Dealer with written notice specifying (i) Counterparty’s average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the date of such Public Announcement that were not effected through Dealer or its affiliates and (ii) the number of Shares purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding the date of such Public Announcement. Such written notice shall be deemed to be a certification by Counterparty to Dealer that such information is true and correct. In addition, Counterparty shall promptly notify Dealer of the earlier to occur of the completion of the relevant Merger Transaction and the completion of the vote by target shareholders.

(b)    Counterparty acknowledges that a Public Announcement may cause the terms of any Transaction to be adjusted or such Transaction to be terminated; accordingly, Counterparty acknowledges that in making any Public Announcement, it must comply with the standards set forth in Section 6 above.

(c)    Upon the occurrence of any Public Announcement (whether made by Counterparty or a third party) Dealer in its sole discretion may either (i) elect that the Calculation Agent shall make adjustments to the terms of any Transaction to account for the economic effect of such Public Announcement on such Transaction (other than

changing the designation of any Calculation Date), including, without limitation, the Scheduled Termination Date or the Forward Price Adjustment Amount, and/or suspend the Calculation Period and/or any Settlement Valuation Period or (ii) treat the occurrence of such Public Announcement as an Additional Termination Event with Counterparty as the sole Affected Party and the Transactions hereunder as the Affected Transactions and with the amount under Section 6(e) of the Agreement determined taking into account the fact that the Calculation Period or Settlement Valuation Period, as the case may be, had fewer Scheduled Trading Days than originally anticipated.

“Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalization as contemplated by Rule 10b-18(a)(13)(iv) under the Exchange Act.

9.Special Provisions for Acquisition Transaction Announcements. (a) If an Acquisition Transaction Announcement occurs on or prior to the Settlement Date for any Transaction, then the Calculation Agent shall make such adjustments to the exercise, settlement, payment or any other terms of such Transaction as the Calculation Agent determines appropriate, at such time or at multiple times as the Calculation Agent determines appropriate, to account for the economic effect on such Transaction of such Acquisition Transaction Announcement (including adjustments to account for changes in volatility, expected dividends, stock loan rate and liquidity relevant to the Shares or to such Transaction). If an Acquisition Transaction Announcement occurs after the Trade Date, but prior to the First Acceleration Date of any Transaction, the First Acceleration Date shall be the date of such Acquisition Transaction Announcement.

(b)    “Acquisition Transaction Announcement” means (i) the announcement of an Acquisition Transaction, (ii) an announcement that Counterparty or any of its subsidiaries has entered into an agreement, a letter of intent or an understanding designed to result in an Acquisition Transaction, (iii) the announcement of the intention to solicit or enter into, or to explore strategic alternatives or other similar undertaking that could reasonably be expected to include, an Acquisition Transaction, (iv) any other announcement that in the reasonable judgment of the Calculation Agent may result in an Acquisition Transaction or (v) any announcement of any change or amendment to any previous Acquisition Transaction Announcement (including any announcement of the abandonment of any such previously announced Acquisition Transaction, agreement, letter of intent, understanding or intention). For the avoidance of doubt, announcements as used in the definition of Acquisition Transaction Announcement refer to any public announcement whether made by the Issuer or a third party.

(c)    “Acquisition Transaction” means (i) any Merger Event (for purposes of this definition the definition of Merger Event shall be read with the references therein to “100%” being replaced by “20%” and to “50%” by “75%” and without reference to the clause beginning immediately following the definition of Reverse Merger therein to the end of such definition), Tender Offer or Merger Transaction or any other transaction involving the merger of Counterparty with or into any third party, (ii) the sale or transfer of all or substantially all of the assets of Counterparty, (iii) a recapitalization, reclassification, binding share exchange or other similar transaction with respect to Counterparty, (iv) any acquisition, lease, exchange, transfer, disposition (including by way of spin-off or distribution) of assets (including any capital stock or other ownership interests in subsidiaries) or other similar event by Counterparty or any of its subsidiaries where the aggregate consideration transferable or receivable by or to Counterparty or its subsidiaries exceeds 15% of the market capitalization of Counterparty and (v) any transaction in which Counterparty or its board of directors has a legal obligation to make a recommendation to its shareholders in respect of such transaction (whether pursuant to Rule 14e-2 under the Exchange Act or otherwise).

(iii)a party’s right to liquidate, terminate or accelerate any Transaction, net out or offset termination values or payment amounts, and to exercise any other remedies upon the occurrence of any Event of Default or Termination Event under the Agreement with respect to the other party or any Extraordinary Event that results in the termination or cancellation of any Transaction to constitute a “contractual right” (as defined in the Bankruptcy Code); and

(iv)all payments for, under or in connection with each Transaction, all payments for the Shares (including, for the avoidance of doubt, payment of the Prepayment Amount) and the transfer of such Shares to constitute “settlement payments” and “transfers” (as defined in the Bankruptcy Code).

(b)    Counterparty acknowledges that:

(i)    during the term of any Transaction, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to establish, adjust or unwind its hedge position with respect to such Transaction;

(ii)    Dealer and its affiliates may also be active in the market for the Shares and derivatives linked to the Shares other than in connection with hedging activities in relation to any Transaction, including acting as agent or as principal and for its own account or on behalf of customers;

(iii)    Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in Counterparty’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price and the VWAP Price;

(iv)    any market activities of Dealer and its affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and VWAP Price, each in a manner that may be adverse to Counterparty; and

(v)    each Transaction is a derivatives transaction in which it has granted Dealer an option; Dealer may purchase shares for its own account at an average price that may be greater than, or less than, the price paid by Counterparty under the terms of the related Transaction.

(c)    Counterparty:

(i)is an “institutional account” as defined in FINRA Rule 4512(c);

(ii)is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities, and will exercise independent judgment in evaluating the recommendations of Dealer or its associated persons unless it has otherwise notified Dealer in writing; and

(iii)will notify Dealer if any of the statements contained in clause (i) or (ii) of this Section 10(c) ceases to be true.

11.Credit Support Documents. The parties hereto acknowledge that no Transaction hereunder is secured by any collateral that would otherwise secure the obligations of Counterparty herein or pursuant to the Agreement.

12.Set-off. (a) The parties agree to amend Section 6 of the Agreement by adding a new Section 6(f) thereto as follows:

“(f) Upon the occurrence of an Event of Default or Termination Event with respect to a party who is the Defaulting Party or the Affected Party (“X”), the other party (“Y”) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X owed to Y (or any Affiliate of Y) (whether or not matured or contingent and whether or not

arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y (or any Affiliate of Y) owed to X (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation). Y will give notice to the other party of any set-off effected under this Section 6(f).

Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency. If any obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained. Nothing in this Section 6(f) shall be effective to create a charge or other security interest. This Section 6(f) shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).”

(b)    Notwithstanding anything to the contrary in the foregoing, Dealer agrees not to set off or net amounts due from Counterparty with respect to any Transaction against amounts due from Dealer to Counterparty with respect to contracts or instruments that are not Equity Contracts. “Equity Contract” means any transaction or instrument that does not convey to Dealer rights, or the ability to assert claims, that are senior to the rights and claims of common stockholders in the event of Counterparty’s bankruptcy.

13.Delivery of Shares. Notwithstanding anything to the contrary herein, Dealer may, by prior notice to Counterparty, satisfy its obligation to deliver any Shares or other securities on any date due (an “Original Delivery Date”) by making separate deliveries of Shares or such securities, as the case may be, at more than one time on or prior to such Original Delivery Date, so long as the aggregate number of Shares and other securities so delivered on or prior to such Original Delivery Date is equal to the number required to be delivered on such Original Delivery Date.

14.Early Termination. In the event that an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with respect to any Transaction (except as a result of a Merger Event in which the consideration or proceeds to be paid to holders of Shares consists solely of cash), if either party would owe any amount to the other party pursuant to Section 6(d)(ii) of the Agreement (any such amount, a “Payment Amount”), then, in lieu of any payment of such Payment Amount, Counterparty may, no later than the Early Termination Date or the date on which such Transaction is terminated, elect to deliver or for Dealer to deliver, as the case may be, to the other party a number of Shares (or, in the case of a Merger Event, a number of units, each comprising the number or amount of the securities or property that a hypothetical holder of one Share would receive in such Merger Event (each such unit, an “Alternative Delivery Unit” and, the securities or property comprising such unit, “Alternative Delivery Property”)) with a value equal to the Payment Amount, as determined by the Calculation Agent (and the parties agree that, in making such determination of value, the Calculation Agent may take into account a number of factors, including the market price of the Shares or Alternative Delivery Property on the date of early termination and, if such delivery is made by Dealer, the prices at which Dealer purchases Shares or Alternative Delivery Property on any Calculation Date to fulfill its delivery obligations under this Section 14); provided that in determining the composition of any Alternative Delivery Unit, if the relevant Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash; and provided further that Counterparty may make such election only if Counterparty represents and warrants to Dealer in writing on the date it notifies Dealer of such election that, as of such date, Counterparty is not aware of any material non-public information concerning the Shares and is making such election in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws. If such delivery is made by Counterparty, paragraphs 2 through 7 of Annex A shall apply as if such delivery were a settlement of the Transaction to which Net Share Settlement applied, the Cash Settlement Payment Date were the Early Termination Date and the Forward Cash Settlement Amount were zero (0) minus the Payment Amount owed by Counterparty.

15.Calculations and Payment Date upon Early Termination. The parties acknowledge and agree that in calculating Loss pursuant to Section 6 of the Agreement Dealer may (but need not) determine losses without reference to actual losses incurred but based on expected losses assuming a commercially reasonable (including without limitation with regard to reasonable legal and regulatory guidelines) risk bid were used to determine loss to avoid awaiting the delay associated with closing out any hedge or related trading position in a commercially reasonable manner prior to or promptly following the designation of an Early Termination Date. Notwithstanding anything to the contrary herein or in Section 6(d)(ii) of the Agreement or in the Equity Definitions, all amounts calculated as being due in respect of an Early Termination Date under Section 6(e) of the Agreement or other termination or cancellation of a Transaction hereunder will be payable on the day that notice of the amount payable is effective; provided that if Counterparty elects to receive Shares or Alternative Delivery Property in accordance with Section 14, such Shares or Alternative Delivery Property shall be delivered on a date selected by Dealer as promptly as practicable.

16.Dealer Purchases. During any Relevant Period or, if applicable, Settlement Valuation Period, Dealer shall not purchase any Shares or enter into any transactions that, in whole or in part, have the effect of giving Dealer “long” economic exposure to the Shares in connection with any Transaction on any Exchange Business Day that is not a Calculation Date; provided that (i) Dealer shall be permitted on any day to exercise listed options relating to Shares or deliver or receive Shares upon exercise of listed options relating to Shares, in either case so long as such options were purchased or written in compliance with this sentence and (ii) during the period (if any) from and including the Trade Date to but excluding the Calculation Period Start Date, Dealer shall be permitted to enter into delta-neutral volatility hedging transactions so long as such transactions (with such transactions entered into with the same counterparty viewed in the aggregate) do not result in an immediate increase in Dealer’s net “long” exposure to the Shares and do not involve open market purchases of Shares.

17.Automatic Termination Provisions. Notwithstanding anything to the contrary in Section 6 of the Agreement, if a Termination Price is specified in any Supplemental Confirmation, then an Additional Termination Event with Counterparty as the sole Affected Party and the Transaction to which such Supplemental Confirmation relates as the Affected Transaction will automatically occur without any notice or action by Dealer or Counterparty if the VWAP Price for any Exchange Business Day is below such Termination Price, and such Exchange Business Day will be the “Early Termination Date” for purposes of the Agreement.

18.Delivery of Cash. For the avoidance of doubt, nothing in this Master Confirmation shall be interpreted as requiring Counterparty to deliver cash in respect of the settlement of the Transactions contemplated by this Master Confirmation following payment by Counterparty of the relevant Prepayment Amount, except in circumstances where the required cash settlement thereof is permitted for classification of the contract as equity by ASC 815-40, Derivatives and Hedging - Contracts in Entity’s Own Equity, as in effect on the relevant Trade Date (including, without limitation, where Counterparty so elects to deliver cash or fails timely to elect to deliver Shares or Alternative Delivery Property in respect of the settlement of such Transactions).

19.Claim in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with respect to the Transactions that are senior to the claims of common stockholders in the event of Counterparty’s bankruptcy.

20.Governing Law. The Agreement, this Master Confirmation, each Supplemental Confirmation and all matters arising in connection with the Agreement, this Master Confirmation and each Supplemental Confirmation shall be governed by, and construed and enforced in accordance with, the laws of the State of New York (without reference to its choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law).

21.Illegality. The parties agree that, for the avoidance of doubt, for purposes of Section 5(b)(i) of the Agreement, “any applicable law” shall include the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, any rules and regulations promulgated thereunder and any similar law or regulation, without regard to Section 739 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 or any similar legal certainty provision in any legislation enacted, or rule or regulation promulgated, on or after the Trade Date, and the consequences specified in the Agreement, including without limitation, the consequences specified in Section 6 of the Agreement, shall apply to any Illegality arising from any such act, rule or regulation.

(a)    The Office of Dealer for each Transaction is: 200 West Street, New York, New York 10282-2198.

(b)    The Office of Counterparty for each Transaction is: 550 South Tryon Street, Charlotte, North Carolina ###-###-####.

25.Counterparts. This Master Confirmation may be executed in any number of counterparts, all of which shall constitute one and the same instrument, and any party hereto may execute this Master Confirmation by signing and delivering one or more counterparts.

26.Calculations and Adjustments. For the avoidance of doubt, any calculation, adjustment or other determination made by Dealer, the Calculation Agent or a Determining Party hereunder will be provided to Counterparty on or prior to the effective date thereof or the effective date of any notice of an amount payable in respect thereof (including any such notice referenced in Section 6(d)(ii) of the Agreement) in a written statement showing, in reasonable detail, such calculation, adjustment or other determination and the basis therefor (including any quotations, market data and information from internal or external sources used in making such calculation, adjustment or other determination), it being understood that no person preparing or furnishing any such written statement shall have an obligation to disclose proprietary or confidential information; provided that in the case of determinations that are not calculations or adjustments, such a statement shall be required only to the extent that such a statement is reasonably necessary to show such determination or the basis therefor because such

determination or basis is not apparent, and such a statement shall not be required where such determination is stated to be at Dealer’s sole election or discretion.

Counterparty hereby agrees (a) to check this Master Confirmation carefully and immediately upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement between Dealer and Counterparty with respect to any particular Transaction to which this Master Confirmation relates, by manually signing this Master Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy to Equity Derivatives Documentation Department, Facsimile No. 212 ###-###-####/83.

5.    This Supplemental Confirmation may be executed in any number of counterparts, all of which shall constitute one and the same instrument, and any party hereto may execute this Supplemental Confirmation by signing and delivering one or more counterparts.

Counterparty hereby agrees (a) to check this Supplemental Confirmation carefully and immediately upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement between Dealer and Counterparty with respect to the Transaction to which this Supplemental Confirmation relates, by manually signing this Supplemental Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy to Equity Derivatives Documentation Department, Facsimile No. 212 ###-###-####/83.

Agreed and Accepted By:

1.    The following Counterparty Settlement Provisions shall apply to the extent indicated under the Master Confirmation:

Settlement Method

Forward Cash Settlement

Cash Settlement

Net Share Settlement

2.    Net Share Settlement shall be made by delivery on the Cash Settlement Payment Date of a number of Shares satisfying the conditions set forth in paragraph 3 below (the “Registered Settlement Shares”), or a number of Shares not satisfying such conditions (the “Unregistered Settlement Shares”), in either case with a value equal to the absolute value of the Forward Cash Settlement Amount, with such Shares’ value based on the value thereof to Dealer (which value shall, in the case of Unregistered Settlement Shares, take into account a commercially reasonable illiquidity discount), in each case as determined by the Calculation Agent.

3.    Counterparty may only deliver Registered Settlement Shares pursuant to paragraph 2 above if:

(a)    a registration statement covering public resale of the Registered Settlement Shares by Dealer (the “Registration Statement”) shall have been filed with the Securities and Exchange Commission under the Securities Act and been declared or otherwise become effective on or prior to the date of delivery, and no stop order shall be in effect with respect to the Registration Statement; a printed prospectus relating to the Registered Settlement Shares (including any prospectus supplement thereto, the “Prospectus”) shall have been delivered to Dealer, in such quantities as Dealer shall reasonably have requested, on or prior to the date of delivery;

(b)    the form and content of the Registration Statement and the Prospectus (including, without limitation, any sections describing the plan of distribution) shall be satisfactory to Dealer;

(c)    as of or prior to the date of delivery, Dealer and its agents shall have been afforded a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities and the results of such investigation are satisfactory to Dealer, in its discretion; and

(d)    as of the date of delivery, an agreement (the “Underwriting Agreement”) shall have been entered into with Dealer in connection with the public resale of the Registered Settlement Shares by Dealer substantially similar to underwriting agreements customary for underwritten offerings of equity securities, in form and substance reasonably satisfactory to Dealer, which Underwriting Agreement shall include, without limitation, provisions substantially similar to those contained in such underwriting agreements relating, without limitation, to the mutual indemnification of, and contribution in connection with the liability of, the parties and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters.

4.    If Counterparty delivers Unregistered Settlement Shares pursuant to paragraph 2 above:

(a)    all Unregistered Settlement Shares shall be delivered to Dealer (or any affiliate of Dealer designated by Dealer) pursuant to the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof;

(b)    as of or prior to the date of delivery, Dealer and any potential purchaser of any such shares from Dealer (or any affiliate of Dealer designated by Dealer) identified by Dealer shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for similarly-sized private placements of equity securities (including, without limitation, the right to have made available to them for inspection all financial and other records, pertinent corporate documents and other information reasonably requested by them); provided that, prior to receiving or being granted access to any such information, any such potential purchaser may be required by Counterparty to enter into a customary non-disclosure agreement with Counterparty in respect of any such due diligence investigation;

(c)    as of the date of delivery, Counterparty shall enter into an agreement (a “Private Placement Agreement”) with Dealer (or any affiliate of Dealer designated by Dealer) in connection with the private placement of such shares by Counterparty to Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance commercially reasonably satisfactory to Dealer, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating, without limitation, to the mutual indemnification of, and contribution in connection with the liability of, the parties and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Counterparty of all reasonable fees and expenses in connection with such resale, including all reasonable fees and expenses of counsel for Dealer, and shall contain representations, warranties, covenants and agreements of Counterparty reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales; and

(d)    in connection with the private placement of such shares by Counterparty to Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), Counterparty shall, if so requested by Dealer, prepare, in cooperation with Dealer, a private placement memorandum in form and substance reasonably satisfactory to Dealer.

5.    Dealer, itself or through an affiliate (the “Selling Agent”) or any underwriter(s), will sell in a commercially reasonable manner all, or such lesser portion as may be required hereunder, of the Registered Settlement Shares or Unregistered Settlement Shares and any Makewhole Shares (as defined below) (together, the “Settlement Shares”) delivered by Counterparty to Dealer pursuant to paragraph 6 below commencing on the Cash Settlement Payment Date and continuing until the date on which the aggregate Net Proceeds (as such term is defined below) of such sales, as determined by Dealer, is equal to the absolute value of the Forward Cash Settlement Amount (such date, the “Final Resale Date”). If the proceeds of any sale(s) made by Dealer, the Selling Agent or any underwriter(s), net of any reasonable fees and commissions (including, without limitation, underwriting or placement fees) customary for similar transactions under the circumstances at the time of the offering, together with reasonable carrying charges and expenses incurred in connection with the offer and sale of the Shares (including, but without limitation to, the covering of any over-allotment or short position (syndicate or otherwise)) (the “Net Proceeds”) exceed the absolute value of the Forward Cash Settlement Amount, Dealer will refund, in USD (or, at Counterparty’s election, Shares of equivalent value, as determined by the Calculation Agent), such excess to Counterparty on the date that is three (3) Currency Business Days following the Final Resale Date (or, in the case of such a refund in Shares, commercially reasonably promptly thereafter), and, if any portion of the Settlement Shares remains unsold, Dealer shall return to Counterparty on that date such unsold Shares.

6.    If the Calculation Agent determines that the Net Proceeds received from the sale of the Registered Settlement Shares or Unregistered Settlement Shares or any Makewhole Shares, if any, pursuant to this paragraph 6 are less than the absolute value of the Forward Cash Settlement Amount (the amount in USD by which the Net Proceeds are less than the absolute value of the Forward Cash Settlement Amount being the “Shortfall” and the date on which such determination is made, the “Deficiency Determination Date”), Counterparty shall on the Calculation Date next succeeding the Deficiency Determination Date (the “Makewhole Notice Date”) deliver to Dealer, through the Selling Agent, a notice of Counterparty’s election that Counterparty shall either (i) pay an amount in cash equal to the Shortfall on the day that is one (1) Currency Business Day after the Makewhole Notice Date, or (ii) deliver additional Shares. If Counterparty elects to deliver to Dealer additional Shares, then Counterparty shall deliver additional Shares in compliance with the terms and conditions of paragraph 3 or paragraph 4 above, as the case may be (the “Makewhole Shares”), on the first Clearance System Business Day which is also a Calculation Date following the Makewhole Notice Date in such number as the Calculation Agent reasonably believes would have a market value on that Calculation Date equal to the Shortfall. Such Makewhole Shares shall be sold by Dealer in accordance with the provisions above; provided that if the sum of the Net Proceeds from the sale of the originally delivered Shares and the Net Proceeds from the sale of any Makewhole Shares is less than the absolute value of the Forward Cash Settlement Amount then Counterparty shall, at its election, either make such cash payment or deliver to Dealer further Makewhole Shares until such Shortfall has been reduced to zero.

7.    Notwithstanding the foregoing, in no event shall the aggregate number of Settlement Shares and Makewhole Shares be greater than the Reserved Shares minus the amount of any Shares actually

delivered by Counterparty under any other Transaction(s) under this Master Confirmation (the result of such calculation, the “Capped Number”). Counterparty represents and warrants (which shall be deemed to be repeated on each day that a Transaction is outstanding) that the Capped Number is equal to or less than the number of Shares determined according to the following formula:

B = the maximum number of Shares required to be delivered to third parties if Counterparty elected Net Share Settlement of all transactions in the Shares (other than Transactions in the Shares under this Master Confirmation) with all third parties that are then currently outstanding and unexercised.

“Reserved Shares” means, initially, 19,490,000 Shares. The Reserved Shares may be increased or decreased in a Supplemental Confirmation.
