The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the Transaction entered into between [Dealer] (“Dealer”), through its agent [Agent] (the “Agent”), and Duke Energy Corporation (“Counterparty”), on the Trade Date specified below (the “Transaction”).  This Confirmation constitutes a “Confirmation” as referred to in the Agreement specified below.  This Confirmation is a confirmation for purposes of Rule 10b-10 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

This Confirmation evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates and supersedes all prior or contemporaneous written or oral communications with respect thereto. This Confirmation, together with any other Confirmations for registered forward transactions entered into between Dealer and Counterparty (each, an “Additional Confirmation”), shall supplement, form a part of, and be subject to an agreement (the “Agreement”) in the form of the 1992 ISDA Master Agreement (Multicurrency — Cross Border) as if Dealer and Counterparty had executed an agreement in such form (without any Schedule but with the elections set forth in this Confirmation) on the Trade Date. The Transaction and the Transactions to which the Additional Confirmations, if any, relate (each, an “Additional Transaction”) 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, other than the Additional Confirmations, 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 Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

The definitions and provisions contained in the 2006 ISDA Definitions (the “Swap Definitions”) and the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”) as published by the International Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation.  Any reference to a currency shall have the meaning contained in Section 1.7 of the 2006 ISDA Definitions as published by ISDA.

THIS CONFIRMATION AND THE AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO CHOICE OF LAW DOCTRINE THAT WOULD APPLY THE LAWS OF ANOTHER JURISDICTION.  NOTWITHSTANDING THE FOREGOING, OR ANYTHING TO THE CONTRARY IN THIS CONFIRMATION OR THE AGREEMENT, COUNTERPARTY DOES NOT BY THIS CONFIRMATION OR THE TRANSACTION HEREUNDER SUBMIT TO THE JURISDICTION OF ANY FOREIGN NATION OR FOREIGN SUPRANATIONAL ORGANIZATION OR SUCH ENTITY’S LAWS OR REGULATIONS, INCLUDING WITHOUT LIMITATION THE EUROPEAN MARKET INFRASTRUCTURE REGULATION.  THIS CONFIRMATION, THE AGREEMENT AND THE TRANSACTION ARE INTENDED TO BE GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK AND NOT THE LAWS, RULES OR REGULATIONS OF ANY FOREIGN JURISDICTION.

THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES DISTRICT COURT LOCATED IN THE BOROUGH OF MANHATTAN IN NEW YORK CITY IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH RESPECT TO, THESE COURTS.

(i)                                     Shares are sold by [the Agent] acting as forward seller for Dealer on or after the Trade Date; and

(ii)                                  Such shares are sold on or before the Hedge Completion Date;

(b)                                 If the Equity Distribution Agreement is terminated prior to any such sale of the Shares thereunder during such period, the parties shall have no further obligations in connection with this Transaction.

5.                                      Representations and Agreements of Counterparty:  Counterparty represents and warrants to, and agrees with, Dealer as of the date hereof that:

(a)                                 Counterparty shall promptly provide written notice to Dealer upon obtaining knowledge of (i) the occurrence or announcement of any event that would constitute an Event of Default as to which it is the Defaulting Party or a Potential Adjustment Event or (ii) any Announcement Date in respect of an Extraordinary Event; provided that should Counterparty be in possession of material non-public information regarding Counterparty, Counterparty shall not communicate such information to Dealer;

(b)                                 Counterparty will keep available at all times, for the purpose of issuance upon settlement of the Transaction as herein provided, the maximum number of Shares of Counterparty as may be issuable upon settlement of the Transaction.  The Shares of Counterparty issuable from time to time upon settlement of the Transaction have been duly authorized and, when delivered as contemplated by the terms of the Transaction upon settlement of the Transaction, will be validly issued, fully-paid and non-assessable, and the issuance of such Shares will not be subject to any pre-emptive or similar rights;

(c)                                  [RESERVED]

(d)                                 Counterparty shall not take any action to reduce or decrease the number of authorized and unissued Shares below the sum of (i) the maximum number specified in clause (b) above plus (ii) the total number of Shares issuable upon settlement (whether by net share settlement or otherwise) of any other transaction or agreement to which it is a party (or, if greater, the number of Shares reserved by Counterparty for settlement of or delivery under such transaction or agreement);

(e)                                  Counterparty will not repurchase any Shares if, immediately following such repurchase, the Outstanding Share Percentage would be equal to or greater than 8.5%, and it will notify Dealer promptly upon the announcement or consummation of any repurchase of Shares that, taken together with the amount of all repurchases since the date of the last such notice (or, if no such notice has been given, the Trade Date), would increase such percentage by more than 1% of the number of then-outstanding Shares.  The “Outstanding Share Percentage” as of any day

13

is a fraction (1) the numerator of which is the aggregate of the Number of Shares for this Transaction and the “Number of Shares” (as defined in the applicable Additional Confirmation) under any outstanding Additional Transactions and (2) the denominator of which is the total number of Shares outstanding on such day;

(f)                                   As of the Trade Date and as of the date of any payment or delivery by Counterparty or Dealer hereunder, it is not and will not be “insolvent” (as such term is defined under Section 101(32) of the Bankruptcy Code);

(g)                                  Neither Counterparty nor any of its “affiliated purchasers” (as defined by Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall take any action that would cause any purchases of Shares by Dealer or any of its affiliates in connection with any Cash Settlement or Net Share Settlement not to meet the requirements of the safe harbor provided by Rule 10b-18 if such purchases were made by Counterparty.  Without limiting the generality of the foregoing, during any Unwind Period, except with the prior written consent of Dealer, Counterparty will not, and will cause its affiliated purchasers (as defined in Rule 10b-18) not to, directly or indirectly (including, without limitation, by means of a derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or announce or commence any tender offer relating to, any Shares (or equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable for the Shares.  However, the foregoing shall not (a) limit Counterparty’s ability, pursuant to any issuer “plan” (as defined in Rule 10b-18), 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 any issuer “plan” (as defined in Rule 10b-18) for directors, officers and employees or any agreements with respect to any such plan for 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);

(h)                                 Counterparty will not engage in any “distribution” (as defined in Regulation M promulgated under the Exchange Act (“Regulation M”))

14

that would cause a “restricted period” (as defined in Regulation M) to occur during any Unwind Period;

(i)                                     During any Unwind Period, Counterparty shall: (i) prior to the opening of trading in the Shares on any day on which Counterparty makes, or expects to be made, any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction, to the extent permitted by applicable law but in no event later than the time such announcement is first made, notify Dealer of such public announcement; (ii) promptly notify Dealer following any such announcement that such announcement has been made; (iii) promptly (but in any event prior to the next opening of the regular trading session on the Exchange) provide Dealer with written notice specifying (A) Counterparty’s average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the related announcement date that were not effected through Dealer or its affiliates, if any, and (B) the number of Shares, if any, purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding such announcement date.  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 such transaction and the completion of the vote by target shareholders.  Counterparty acknowledges that any such notice may result in a Regulatory Disruption or may affect the length of any ongoing Unwind Period; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 11(c) of this Confirmation.  “Securities Act” means the Securities Act of 1933, as amended.  “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;

(k)                                 Counterparty is not entering into the Transaction, and will not elect Cash Settlement or Net Share Settlement, to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for Shares), in either case in violation of the Exchange Act or any other applicable securities laws;

(l)                                     Counterparty (i) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (ii) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its

(m)                             Without limiting the generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that Dealer is not making any representations or warranties with respect to the treatment of the Transaction, including without limitation ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, FASB Statements 128, 133, as amended, 149 or 150, EITF 00-19, 01-6, 03-6 or 07-5, ASC Topic 480, Distinguishing Liabilities from Equity, ASC 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity (or any successor issue statements) or under the Financial Accounting Standards Board’s Liabilities & Equity Project;

(n)                                 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;

(o)                                 Counterparty is not aware of any material non-public information regarding itself or the Shares; Counterparty is entering into this Confirmation and will provide any settlement method election notice in good faith and not as part of a plan or scheme to evade compliance with Rule 10b-5 or any other provision of the federal securities laws; and Counterparty has consulted with its own advisors as to the legal aspects of its adoption and implementation of this Confirmation under Rule 10b5-1 under the Exchange Act (“Rule 10b5-1”);

(p)                                 [RESERVED]

(q)                                 Counterparty is not, and after giving effect to the transactions contemplated hereby will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended;

(r)                                    Counterparty understands, agrees and acknowledges that no obligations of Dealer to it hereunder shall be entitled to the benefit of deposit insurance and that such obligations shall not be guaranteed by any affiliate of Dealer or any governmental agency;

(t)                                    COUNTERPARTY UNDERSTANDS THAT THE TRANSACTION IS SUBJECT TO COMPLEX RISKS WHICH MAY ARISE WITHOUT WARNING AND MAY AT TIMES BE VOLATILE AND THAT LOSSES MAY OCCUR QUICKLY AND IN UNANTICIPATED MAGNITUDE AND IS WILLING TO ACCEPT SUCH TERMS AND CONDITIONS AND ASSUME (FINANCIALLY AND OTHERWISE) SUCH RISKS.

6.                                      Issuance of Shares by Counterparty:  Counterparty acknowledges and agrees that any Shares delivered by Counterparty to Dealer on any Settlement Date or Net Share Settlement Date will be newly issued. Counterparty further acknowledges and agrees that, except to the extent that the Private Placement Procedures in Annex A apply, any Shares delivered by Counterparty to Dealer on any Settlement Date or Net Share Settlement Date will be (i) approved for listing or quotation on the Exchange, subject to official notice of issuance and (ii) registered under the Exchange Act.  On the basis of the Forward Letter (as hereinafter defined), such Shares, when delivered by Dealer (or an affiliate of Dealer) to securities lenders from whom Dealer (or an affiliate of Dealer) borrowed Shares in connection with hedging its exposure to the Transaction, will be freely saleable without further registration or other restrictions under the Securities Act in the hands of those securities lenders, irrespective of whether any such stock loan is effected by Dealer or an affiliate of Dealer.  Accordingly, Counterparty agrees that, except to the extent that the Private Placement Procedures in Annex A apply, any Shares so delivered will not bear a restrictive legend and will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

7.                                      Termination on Bankruptcy:  The parties hereto agree that, notwithstanding anything to the contrary in the Agreement or the Equity Definitions, the Transaction constitutes a contract to issue a security of Counterparty as contemplated by Section 365(c)(2) of the Bankruptcy Code (as defined below) and that the Transaction and the obligations and rights of Counterparty and Dealer (except for any liability as a result of breach of any of the representations or warranties provided by Counterparty in Section 5 above) shall immediately terminate, without the necessity of any notice, payment (whether directly, by netting or otherwise) or other action by Counterparty or Dealer, if, on or prior to the final Settlement Date, Cash Settlement Payment Date or Net Share Settlement Date, an Insolvency Filing occurs (a “Bankruptcy Termination Event”).

8.                                      Special Dividends:  If an ex-dividend date for a Special Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Counterparty to Dealer in settlement of the Transaction), Counterparty shall pay to Dealer on the earlier of (i) the date on which such Special Dividend is paid by the Issuer to holders of record of the Shares, (ii) the Designated Date where the Undesignated Shares

9.                                      Acceleration Events:

(a)                                 Notwithstanding anything to the contrary herein, in the Agreement or in the Equity Definitions, at any time following the occurrence and during the continuation of an Acceleration Event, Dealer (or, in the case of an Acceleration Event that is an Event of Default or a Termination Event, the party that would be entitled to designate an Early Termination Date in respect of such event pursuant to Section 6 of the Agreement) shall, by not more than 20 days’ notice to the other party, have the right to designate by notice to the other party any Scheduled Trading Day not earlier than the day such notice is effective to be the “Early Valuation Date” but which, in the case of an Acceleration Event that results from the commencement of any proceeding with respect to Counterparty under the Bankruptcy Code other than in a Bankruptcy Termination Event, shall be the Scheduled Trading Day on which such proceeding is commenced (or, if not commenced on such a day, the following Scheduled Trading Day), in which case the provisions set forth in this Section 9 shall apply in lieu of Section 6 of the Agreement or Article 12 of the Equity Definitions.

(b)                                 If the Early Valuation Date occurs on a date that is not during an Unwind Period, then the Early Valuation Date shall be deemed to be a Designated Date for a Physical Settlement, and the number of Designated Shares for such Designated Date shall be the number of Undesignated Shares on the Early Valuation Date; provided that in the case of an Acceleration Event of the type described in paragraph (e)(iii) or (iv) below, the number of Designated Shares for such Designated Date shall be only such number of Designated Shares necessary so that such Acceleration Event shall no longer exist after such Physical Settlement, as determined by the Calculation Agent; and, provided, further, that in the case of an Acceleration Event of the type described in paragraph (e)(i) below and resulting from the commencement of any proceeding with respect to Counterparty under the Bankruptcy Code other than in a Bankruptcy

18

Termination Event, the Early Valuation Date shall be deemed to be the last Unwind Date for a Cash Settlement and in such case the aggregate net loss or cost reasonably determined by Dealer as of the related Early Valuation Date in connection with unwinding its Hedge Positions shall be added to the Forward Cash Settlement Amount (or, if an aggregate net gain is so determined, such gain shall be subtracted therefrom).

(c)                                  If the Early Valuation Date occurs during an Unwind Period, then (i) (A) the last Unwind Date of such Unwind Period shall occur on the Early Valuation Date, (B) a settlement shall occur in respect of such Unwind Period, and the settlement method elected by Counterparty in respect of such settlement shall apply, and (C) the number of Designated Shares for such settlement shall be deemed to be the number of Unwound Shares for such Unwind Period on the Early Valuation Date, and (ii) (A) the Early Valuation Date shall be deemed to be an additional Designated Date for a Physical Settlement and (B) the number of Designated Shares for such additional Designated Date shall be the Remaining Amount on the Early Valuation Date; provided that in the case of an Acceleration Event of the type described in paragraph (e)(iii) or (iv) below, the number of Designated Shares for such additional Designated Date shall be only such number of Designated Shares necessary so that such Acceleration Event shall no longer exist after such Physical Settlement, as determined by the Calculation Agent; and, provided, further, that in the case of an Acceleration Event of the type described in paragraph (e)(i) below and resulting from the commencement of any proceeding with respect to Counterparty under the Bankruptcy Code other than in a Bankruptcy Termination Event, the Early Valuation Date shall be deemed to be the last Unwind Date of an additional Unwind Period for a Cash Settlement and the number of Designated Shares for such settlement shall be deemed to be the Remaining Amount on the Early Valuation Date and in such case the aggregate net loss or cost reasonably determined by Dealer as of the related Early Valuation Date in connection with unwinding its Hedge Positions shall be added to the Forward Cash Settlement Amount (or, if an aggregate net gain is so determined, such gain shall be subtracted therefrom).

(d)                                 Notwithstanding the foregoing, in the case of an Early Valuation Date that occurs due to an announcement of a Nationalization or a Merger Event, if at the time of the related Settlement Date or Net Share Settlement Date, as applicable, the Shares have changed into cash or any other property or the right to receive cash or any other property, such cash, other property or right shall be deliverable instead of such Shares.

(e)                                  “Acceleration Event” means:

(i)                                   any Event of Default or Termination Event, other than an Event of Default or Termination Event that also constitutes a Bankruptcy

19

Termination Event, that would give rise to the right of either party to designate an Early Termination Date pursuant to Section 6 of the Agreement;

(ii)                                the announcement of any event or transaction that, if consummated, would result in a Merger Event, Tender Offer, Nationalization, Delisting or Change in Law, in each case, as determined by the Calculation Agent;

(iii)                             a Loss of Stock Borrow;

(iv)                            the declaration or payment by Counterparty of any Extraordinary Dividend;

(v)                               the occurrence of a Market Disruption Event during an Unwind Period and the continuance of such Market Disruption Event for at least eight Scheduled Trading Days;

(vi)                            the occurrence of an Excess Section 13 Ownership Position or Excess Regulatory Ownership Position; or

(vii)                         the occurrence of the Maturity Date during an Unwind Period.

10.                               Private Placement Procedures:  If either Dealer or Counterparty reasonably determines in good faith, based on the advice of counsel, that Counterparty will be unable to comply with the covenant set forth in the second sentence of Section 6 of this Confirmation because of a change in law or a change in the policy of the Securities and Exchange Commission (“SEC”) or its staff (the “Staff”), or Dealer otherwise reasonably determines, based on the advice of counsel, that in its reasonable opinion any Shares to be delivered to Dealer by Counterparty hereunder may not be freely returned by Dealer or its affiliates to securities lenders as contemplated by Section 6 of this Confirmation (in either case without regard to exceptions therein), then delivery of any such Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Dealer.

11.                               Rule 10b5-1; Share Purchases by Dealer

(a)                                 The parties acknowledge that, following any election of Cash Settlement or Net Share Settlement by Counterparty, this Confirmation is intended to constitute a binding contract satisfying the requirements of Rule 10b5-1(c) of the Exchange Act and agree that this Confirmation shall be interpreted to comply with such requirements.

(b)                                 The times and prices at which Dealer (or its agent or affiliate) purchases any Shares during any Unwind Period shall be at Dealer’s good faith and commercially reasonable discretion.  Counterparty acknowledges that during any Unwind Period Counterparty does not have, and shall not attempt to exercise, any influence over how, when or whether to effect purchases of Shares or any other transactions by Dealer (or its agent or

20

affiliate) in connection with this Confirmation. Counterparty agrees that during any Unwind Period it will not enter into or alter any corresponding or hedging transaction or position with respect to the Shares.

(c)                                  Counterparty hereby agrees with Dealer that during any Unwind Period Counterparty shall not communicate, directly or indirectly, any material non-public information (within the meaning of such term under Rule 10b5-1) to any employee of Dealer (or its agents or affiliates) who is directly involved with the hedging of, and trading with respect to, the Transaction.  Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of the Transaction must be effected in accordance with the requirements for the amendment or termination of a contract, instruction or plan under 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.

(d)                                 Following any election of Cash Settlement or Net Share Settlement by Counterparty, in addition to the representations, warranties and covenants in the Agreement and elsewhere in this Confirmation, Dealer represents, warrants and covenants to Counterparty that Dealer shall use commercially reasonable efforts, during any Unwind Period, to make all purchases of Shares in connection with such election 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, as if such rule were applicable to such purchases (and considering only such purchases when determining compliance with the foregoing provisions), after taking into account any applicable SEC no-action letters as appropriate, 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 any Unwind 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 in connection with such Settlement (including, for the avoidance of doubt, timing optionality); and provided, further, that, without limiting the generality of the first sentence of this paragraph (d), 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).

12.                               Capped Number of Shares:  Notwithstanding any other provision of the Agreement or this Confirmation, in no event will Counterparty be required to deliver in the aggregate in respect of all Settlement Dates, Net Share Settlement Dates or other dates on which Shares are delivered in respect of any amount owed under this Confirmation a number of Shares greater than the product of 1.5 and the Number of Shares (the “Capped Number”).  Counterparty represents and warrants to Dealer (which representation and warranty shall be deemed to be repeated on each day that the Transaction is outstanding) that the Capped Number is equal to or less than the number of authorized but unissued Shares that are not reserved for future issuance in connection with transactions in the Shares (other than the Transaction) on the date of the determination of the Capped Number (such Shares, the “Available Shares”).  In the event Counterparty shall not have delivered the full number of Shares otherwise deliverable as a result of this Section 12 (the resulting deficit, the “Deficit Shares”), Counterparty shall be obligated to deliver Shares, from time to time until the full number of Deficit Shares have been delivered pursuant to this paragraph, when, and to the extent, that (A) Shares are repurchased, acquired or otherwise received by Counterparty or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration) and are not required to be used for any other purpose, (B) authorized and unissued Shares reserved for issuance in respect of other transactions as of the Trade Date become no longer so reserved and (C)  Counterparty authorizes any additional unissued Shares that are not reserved for other transactions (such events as set forth in clauses (A), (B) and (C) above, collectively, the “Share Issuance Events”).  Counterparty shall promptly notify Dealer of the occurrence of any of the Share Issuance Events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares to be delivered) and, as promptly as reasonably practicable after such Share Issuance Event (or, if later, on the Settlement Date or the date of any Private Placement Settlement for which there are Deficit Shares), deliver such Shares. Counterparty shall not, until Counterparty’s obligations under the Transaction have been satisfied in full, use any Shares that become available for potential delivery to Dealer as a result of any Share Issuance Event for the settlement or satisfaction of any transaction or obligation other than the Transaction, any Additional Transaction and any other transaction under a confirmation entered into by the Company and another dealer pursuant to the Equity Distribution Agreement (each, an “Other Dealer’s Transaction”), or reserve any such Shares for future issuance for any purpose other than to satisfy Counterparty’s obligations to Dealer under the Transaction, any Additional Transaction or any Other Dealer’s Transaction.  Allocation of any Shares that become available for potential delivery to Dealer or any dealer party to an Other Dealer’s Transaction as a result of any Share Issuance Event shall be allocated to the Transaction, any Additional Transaction and any Other Dealer’s Transaction on a ratable basis in accordance with the respective remaining Share delivery obligations thereunder.

13.                               Transfer, Assignment and Designation:

(a)                                 Notwithstanding any provision of the Agreement to the contrary, Dealer may assign, transfer and set over all rights, title and interest, powers, privileges and remedies of Dealer under the Transaction, in whole or part, to an affiliate of Dealer without the consent of Counterparty; provided that (i) no Event of Default, Potential Event of Default or Termination Event with respect to which Dealer or such affiliate is the Defaulting Party or an Affected Party, as the case may be, exists or would result therefrom, (ii)

22

no Acceleration Event or other event giving rise to a right or responsibility to designate an Early Valuation Date or otherwise terminate or cancel the Transaction or to make an adjustment to the terms of the Transaction would result therefrom, and (iii) Counterparty shall not, as a result of such assignment or transfer, (A) be required to pay to Dealer or such affiliate an additional amount in respect of an Indemnifiable Tax, (B) receive a payment from which an amount is required to be deducted or withheld for or on account of a Tax as to which no additional amount is required to be paid, or (C) become subject to the jurisdiction of any state or country other than the United States of America.

(b)                                 Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations.  Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

14.                               Indemnity:  Counterparty agrees to indemnify Dealer and its affiliates and their respective directors, officers, agents and controlling parties (Dealer and each such affiliate or person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, incurred by or asserted against such Indemnified Party, that arise out of, are in connection with, or relate to, a breach of any covenant or representation made by Counterparty in this Confirmation or the Agreement, and Counterparty will reimburse any Indemnified Party for all reasonable expenses (including reasonable legal fees and expenses) in connection with the investigation of, preparation for, or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto. Counterparty will not be liable under this Indemnity paragraph to the extent that any such loss, claim, damage, liability or expense results from an Indemnified Party’s gross negligence, bad faith or willful misconduct or Dealer’s breach of this Confirmation or the Agreement. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability not resulting from its gross negligence, bad faith or willful misconduct, provided that no person guilty of fraudulent misrepresentation shall be entitled to contribution.

15.                               No Collateral; Netting; Setoff:

(a)                                 Notwithstanding any provision of the Agreement or any other agreement between the parties to the contrary, the obligations of Counterparty hereunder are not secured by any collateral.

(b)                                 If on any date any Shares would otherwise be deliverable under the Transaction or any Additional Transaction by Counterparty to Dealer and

23

by Dealer to Counterparty, then, on such date, each party’s obligations to make delivery of such Shares will be automatically satisfied and discharged and, if the aggregate number of Shares that would otherwise have been deliverable by one party exceeds the aggregate number of Shares that would have otherwise been deliverable by the other party, replaced by an obligation upon the party by whom the larger aggregate number of Shares would have been deliverable to deliver to the other party the excess of the larger aggregate number over the smaller aggregate number.

(c)                                  The parties agree that 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 15.

(d)                                 Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency or into Shares, at the election of Y, 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 or Shares.  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 15 shall be effective to create a charge or other security interest.  This Section 15 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).

(e)                                  Notwithstanding anything to the contrary in the foregoing, Dealer agrees not to set off or net amounts due from Counterparty with respect to the Transaction against amounts due from Dealer (or its affiliate) to Counterparty with respect to contracts or instruments that are not Equity Contracts; provided, however, that, and notwithstanding any provision to the contrary set forth in this Confirmation or in the Agreement, Dealer may not use this provision or any other set-off or recoupment right under this Confirmation or the Agreement as a basis for any action under or nonperformance of its obligations under any loan, letter of credit or other borrowing arrangement with Counterparty as borrower and to which Dealer or any affiliate of Dealer is a participating lender, with respect to

24

which the terms of such loan, letter of credit or other borrowing arrangement shall control.  “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.

16.                               Delivery of Cash:  For the avoidance of doubt, nothing in this Confirmation shall be interpreted as requiring Counterparty to deliver cash in respect of the settlement of the Transaction, except (i) as set forth under Section 8 above or (ii) in circumstances where the cash settlement thereof is within Counterparty’s control (including, without limitation, where Counterparty so elects to deliver cash or fails timely to deliver Shares in respect of such settlement).  For the avoidance of doubt, the preceding sentence shall not be construed as limiting any damages that may be payable by Counterparty as a result of a breach of or an indemnity under this Confirmation or the Agreement.

17.                               Status of Claims in Bankruptcy:  Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to this Confirmation and the Agreement; and provided further that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transaction other than the Transaction.

18.                               Limit on Beneficial Ownership:  Notwithstanding anything to the contrary in the Agreement or this Confirmation, in no event shall Dealer be entitled to receive, or be deemed to receive, Shares to the extent that, upon such receipt of such Shares, and after taking into account any Shares concurrently delivered by Seller under any Other Confirmation, (i) the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and the rules promulgated thereunder) of Shares by Dealer, any of its affiliates’ business units subject to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer with respect to “beneficial ownership” of any Shares (collectively, “Dealer Group”) would be equal to or greater than [8.5]% of the outstanding Shares (an “Excess Section 13 Ownership Position”) or (ii) Dealer, Dealer Group or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a “Dealer Person”) under Section 203 of the Delaware General Corporation Law (the “DGCL Takeover Statute”) or any state or federal bank holding company or banking laws, or other federal, state or local laws (including, without limitation, the Federal Power Act), regulations or regulatory orders applicable to ownership of Shares (“Applicable Laws”), would own, beneficially own, constructively own, control, hold the power to vote or otherwise meet a relevant definition of ownership in excess of a number of Shares equal to (x) the lesser of (A) the maximum number of Shares that would be permitted under Applicable Laws and (B) the number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator, such as a state or federal banking regulator or the Federal Energy Regulatory Commission) of a Dealer Person under Applicable Laws (including, without limitation,

25

“interested stockholder” or “acquiring person” status under the DGCL Takeover Statute) and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of Counterparty or any contract or agreement to which Counterparty is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination (such condition described in clause (ii), an “Excess Regulatory Ownership Position”).  Dealer shall notify Counterparty promptly if, at any time, an Excess Section 13 Ownership Position or an Excess Regulatory Ownership Position has occurred or would occur as a result of a delivery by Counterparty to Dealer.  If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Counterparty’s obligation to make such delivery shall not be extinguished and Counterparty shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Dealer gives notice to Counterparty that such delivery would not result in (x) Dealer Group directly or indirectly so beneficially owning in excess of 8.5% of the outstanding Shares or (y) the occurrence of an Excess Regulatory Ownership Position.

19.                               Acknowledgements:

(a)                                 Counterparty acknowledges that:

(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 Settlement Price.

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

(v)                               The Transaction is a derivative transaction; Dealer and its affiliates may purchase or sell Shares for their own account at prices that may be greater than, or less than, the prices paid or received by Counterparty under the terms of the Transaction.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

If Counterparty delivers Restricted Shares pursuant to Section 10 above (a “Private Placement Settlement”), then:

(a)                                 the delivery of Restricted Shares by Counterparty shall be effected in accordance with customary private placement procedures for issuers comparable to Counterparty with respect to such Restricted Shares reasonably acceptable to Dealer.  Counterparty shall not take, or cause to be taken, any action that would make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Counterparty to Dealer (or any affiliate designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(a)(1) or Section 4(a)(3) of the Securities Act for resales of the Restricted Shares by Dealer (or any such affiliate of Dealer);

(b)                                 as of or prior to the date of delivery, Dealer and any potential purchaser of any such Restricted 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 for issuers comparable to Counterparty (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 Restricted Shares by Counterparty to Dealer (or any such affiliate) and the private resale of such Restricted Shares by Dealer (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size for issuers comparable to Counterparty, 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

Annex A-1

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 customary for issuers comparable to Counterparty and 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 Restricted Shares by Counterparty to Dealer (or any such affiliate) and the private resale of such Restricted Shares by Dealer (or any such affiliate), Counterparty shall, if so requested by Dealer, prepare, in cooperation with Dealer, a private placement memorandum customary for comparable private placements and issuers comparable to Counterparty and otherwise in form and substance reasonably satisfactory to Dealer.

In the case of a Private Placement Settlement, Dealer shall, in its good faith discretion, adjust the amount of Restricted Shares to be delivered to Dealer hereunder and/or the applicable Daily Forward Price(s) in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Dealer and may only be saleable by Dealer at a discount to reflect the lack of transferability and liquidity in Restricted Shares based on actual charges incurred or discounts given.

If Counterparty delivers any Restricted Shares in respect of the Transaction, Counterparty agrees that (i) such Shares may be transferred by and among Dealer and its affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Counterparty shall (so long as Dealer or any such affiliate is not an “affiliate” of Counterparty within the meaning of Rule 144 under the Securities Act) promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by Dealer (or such affiliate of Dealer) to Counterparty or such transfer agent of seller’s and broker’s representation letters customarily delivered in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, each without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by Dealer (or such affiliate of Dealer).
