If any Exchange Business Day during an Unwind Period is a Disrupted Day, the Calculation Agent shall make commercially reasonable

4

	adjustments to the terms of the Transaction (including, without limitation, the Cash Settlement Amount and the 10b-18 VWAP) to account for the occurrence of such Disrupted Day.

The effectiveness of this Confirmation on the Effective Date shall be subject to (i) the condition that the representations and warranties of Party B contained in the Purchase Agreement dated the date hereof among Party B and J.P. Morgan Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as Representatives of the Several Underwriters (the “Underwriting Agreement”) and any certificate delivered pursuant thereto by Party B are true and correct on the Effective Date as if made as of the Effective Date, (ii) the condition that Party B have performed all of the obligations required to be performed by it under the Underwriting Agreement on or prior to the Effective Date, (iii) the satisfaction of all of the conditions set forth in Section 5 of the Underwriting Agreement and (iv) the condition that neither of the following has occurred (A) Party A is unable to borrow and deliver for sale a number of Shares equal to the Base Amount, or (B) in Party A’s sole judgment either it is impracticable to do so or Party A would incur a stock loan cost of more than a rate equal to 35 basis points per annum to do so (in which event this Confirmation shall be effective but the Base Amount for this Transaction shall be the number of Shares Party A is required to deliver in accordance with Section 2(a) of the Underwriting Agreement).

Representations and Agreements of Party B:

Party B (i) has such knowledge and experience in financial and business affairs as to be capable of evaluating the merits and risks of entering into this Transaction; (ii) has consulted with its own legal, financial, accounting and tax advisors in connection with this Transaction; and (iii) is entering into this Transaction for a bona fide business purpose.

Party B is not and has not been the subject of any civil proceeding of a judicial or administrative body of competent jurisdiction that could reasonably be expected to impair materially Party B’s ability to perform its obligations hereunder.

Party B will by the next succeeding New York Business Day notify Party A upon obtaining knowledge of the occurrence of any event that would constitute an Event of Default, a Potential Event of Default or a Potential Adjustment Event.

Additional Representations, Warranties and Agreements of Party B: Party B hereby represents and warrants to, and agrees with, Party A as of the date hereof that:

(a) Any Shares, when issued and delivered in accordance with the terms of the Transaction, will be duly authorized and validly issued, fully paid and nonassessable, and the issuance thereof will not be subject to any preemptive or similar rights.

(b) Party B has reserved and will keep available at all times, free from preemptive rights, out of its authorized but unissued Shares, solely for the purpose of issuance upon settlement of the Transaction as herein provided, the full number of Shares as shall be issuable at such time upon settlement of the Transaction. All Shares so issuable shall, upon such issuance, be accepted for listing or quotation on the Exchange.

(c) Party B agrees to provide Party A at least 30 days’ written notice (an “Issuer Repurchase Notice”) prior to executing any repurchase of Shares by Party B or any of its subsidiaries (or entering into any contract that would require, or give the option to, Party B or any of its subsidiaries, to purchase or repurchase Shares), whether out of profits or capital or whether the consideration for such repurchase is cash, securities or otherwise (an “Issuer Repurchase”), that

7

alone or in the aggregate would result in the Base Amount Percentage (as defined below) being (i) equal to or greater than 7.5% of the outstanding Shares and (ii) greater by 0.5% or more than the Base Amount Percentage at the time of the immediately preceding Issuer Repurchase Notice (or in the case of the first such Issuer Repurchase Notice, greater than the Base Amount Percentage as of the later of the date hereof or the immediately preceding Settlement Date, if any). The “Base Amount Percentage” as of any day is the fraction (1) the numerator of which is the Base Amount and (2) the denominator of which is the number of Shares outstanding on such day.

(d) No filing with, or approval, authorization, consent, license registration, qualification, order or decree of, any court or governmental authority or agency, domestic or foreign, is necessary or required for the execution, delivery and performance by Party B of this Confirmation and the consummation of the Transaction (including, without limitation, the issuance and delivery of Shares on any Settlement Date) except (i) such as have been obtained under the Securities Act of 1933, as amended (the “Securities Act”), and (ii) as may be required to be obtained under state securities laws.

(f) Party B is not insolvent, nor will Party B be rendered insolvent as a result of this Transaction.

(g) Neither Party B nor any of its affiliates shall take or refrain from taking any action (including, without limitation, any direct purchases by Party B or any of its affiliates or any purchases by a party to a derivative transaction with Party B or any of its affiliates), either under this Confirmation, under an agreement with another party or otherwise, that might cause any purchases of Shares by Party A or any of its affiliates in connection with any Cash Settlement of this Transaction not to meet the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act if such purchases were made by Party B.

(h) Party B will not engage in any “distribution” (as defined in Regulation M under the Exchange Act (“Regulation M”)) that would cause a “restricted period” (as defined in Regulation M) to occur during any Unwind Period.

(i) Party B is an “eligible contract participant” (as such term is defined in Section 1a(12) of the Commodity Exchange Act, as amended).

(j) In addition to any other requirements set forth herein, Party B agrees not to elect Cash Settlement if, in the reasonable judgment of either Party A or Party B, such settlement or Party A’s related market activity would result in a violation of the U.S. federal securities laws or any other federal or state law or regulation applicable to Party B.

Covenant of Party B:

The parties acknowledge and agree that any Shares delivered by Party B to Party A on any Settlement Date will be newly issued Shares and when delivered by Party A (or an affiliate of Party A) to securities lenders from whom Party A (or an affiliate of Party A) 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 such stock loan is effected by Party A or an affiliate of Party A. Accordingly, Party B agrees that the Shares that it delivers to Party A on each Settlement Date will not bear a restrictive legend and that such Shares will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System.

8

Covenants of Party A:

(a) Unless the provisions set forth below under “Private Placement Procedures” shall be applicable, Party A shall use any Shares delivered by Party B to Party A on any Settlement Date to return to securities lenders to close out open Share loans created by Party A or an affiliate of Party A in the course of Party A’s or such affiliate’s hedging activities related to Party A’s exposure under this Confirmation.

(b) In connection with bids and purchases of Shares in connection with any Cash Settlement of this Transaction, Party A shall use its commercially reasonable efforts to conduct its activities, or cause its affiliates to conduct their activities, in a manner consistent with the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act, as if such provisions were applicable to such purchases.

Insolvency Filing:

Notwithstanding anything to the contrary herein, in the Agreement or in the Definitions, upon any Insolvency Filing in respect of the Issuer, the Transaction shall automatically terminate on the date thereof without further liability of either party to this Confirmation to the other party (except for any liability in respect of any breach of representation or covenant by a party under this Confirmation prior to the date of such Insolvency Filing).

Extraordinary Dividends:

If an ex-dividend date for an Extraordinary Dividend occurs on or after the Trade Date and on or prior to the Maturity Date, Party B shall pay an amount, as determined by the Calculation Agent, in cash equal to the product of such Extraordinary Dividend and the Base Amount to Party A on the earlier of (i) the date on which such Extraordinary Dividend is paid by the Issuer to holders of record of the Shares or (ii) the Maturity Date. “Extraordinary Dividend” means the per Share amount of any cash dividend or distribution declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.

Acceleration Events:

The following events shall each constitute an “Acceleration Event”:

(a) Stock Borrow Events. In the sole judgment of Party A (i) Party A is unable to hedge Party A’s exposure to the Transaction because (A) of the lack of sufficient Shares being made available for Share borrowing by lenders, or (B) it is otherwise commercially impracticable (a “Stock Borrow Event”);

(b) Dividends and Other Distributions. On any day occurring after the Trade Date Party B declares a distribution, issue or dividend to existing holders of the Shares of (i) any cash dividend (other than an Extraordinary Dividend) to the extent all cash dividends having an ex-dividend date during the period from and including any Forward Price Reduction Date (with each of the Trade Date and the Maturity Date being a Forward Price Reduction Date for purposes of this clause (b) only) to but excluding the next subsequent Forward Price Reduction Date exceeds, on a per Share basis, the Forward Price Reduction Amount set forth opposite the first date of any such period on Schedule I or (ii) share capital or securities of another issuer acquired or owned (directly or indirectly) by Party B as a result of a spin-off or other similar transaction or (iii) any other type of securities (other than Shares), rights or warrants or other assets, for payment (cash or other consideration) at less than the prevailing market price as determined by Party A;

9

(c) ISDA Early Termination Date. Either Party A or Party B has the right to designate an Early Termination Date pursuant to Section 6 of the Agreement;

(d) Other ISDA Events. The announcement of any event that if consummated, would result in an Extraordinary Event, or the occurrence of any Change in Law or Delisting; provided that in case of a Delisting, in addition to the provisions of Section 12.6(a)(iii) of the 2002 Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Select Market or the NASDAQ Global Market (or their respective successors); and provided further that the definition of “Change in Law” provided in Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “or public announcement of the formal or informal interpretation” and (ii) immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by Party A on the Trade Date”; or

(e) Issuer Repurchases. Party B publicly announces or discloses any Issuer Repurchase (whether or not subsequently amended) that alone, or in the aggregate, results in, or could result in, the Base Amount representing more than 8.0% of the total outstanding Shares (assuming the consummation of such proposed Issuer Repurchase).

Termination Settlement:

Upon the occurrence of any Acceleration Event, Party A shall have the right to designate, upon at least one Scheduled Trading Day’s notice, any Scheduled Trading Day following such occurrence to be a Settlement Date hereunder (a “Termination Settlement Date”) to which Physical Settlement shall apply, and to select the number of Settlement Shares relating to such Termination Settlement Date; provided that in the case of an Acceleration Event arising out of a Stock Borrow Event the number of Settlement Shares so designated by Party A shall not exceed the number of Shares as to which such Stock Borrow Event exists; provided further that in the case of the announcement of an event that if consummated would result in a Merger Event, Party A shall not have the right to designate a Termination Settlement Date until on or after the date three months prior to the earliest anticipated Merger Date, as determined by the Calculation Agent in its commercially reasonable judgment, for such Acceleration Event. If, upon designation of a Termination Settlement Date by Party A pursuant to the preceding sentence, Party B fails to deliver the Settlement Shares relating to such Termination Settlement Date when due or otherwise fails to perform obligations within its control in respect of this Transaction, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. If an Acceleration Event occurs during an Unwind Period relating to a number of Settlement Shares to which Cash Settlement applies, then on the Termination Settlement Date relating to such Acceleration Event, notwithstanding any election to the contrary by Party B, Cash Settlement shall apply to the portion of the Settlement Shares relating to such Unwind Period as to which Party A has unwound its hedge and Physical Settlement shall apply in respect of (x) the remainder (if any) of such Settlement Shares and (y) the Settlement Shares designated by Party A in respect of such Termination Settlement Date.

Private Placement Procedures

If Party B is unable to comply with the provisions of “Covenant of Party B” above because of a change in law or a change in the policy of the Securities and Exchange Commission or its staff, or Party A otherwise determines that in its reasonable opinion any Settlement Shares to be delivered to Party A by Party B may not be freely returned by Party A or its affiliates to securities lenders as described under “Covenant of Party B” above, then delivery of any such Settlement Shares (the “Restricted Shares”) shall be effected pursuant to Annex A hereto, unless waived by Party A.

Rule 10b5-1:

For the avoidance of doubt and solely by way of illustration, information should be presumed “material” if it relates to such matters as dividend increases or decreases, earnings estimates, changes in previously released earnings estimates, significant expansion or curtailment of operations, a significant increase or decline of orders, significant merger or acquisition proposals or agreements, significant new products or discoveries, extraordinary borrowing, major litigation, liquidity problems, extraordinary management developments, purchase or sale of substantial assets, or other similar information For purposes of this Transaction, “EDG Personnel” means any employee on the trading side of the Equity Derivatives Group of J.P.

Assignment:

Party A may assign or transfer any of its rights or delegate any of its duties hereunder to any affiliate of Party A or any entity organized or sponsored by Party A without the prior written consent of Party B. Notwithstanding any other provision of this Confirmation to the contrary requiring or allowing Party A to purchase or receive any Shares from Party B, Party A may designate any of its affiliates to purchase or receive such Shares or otherwise to perform Party A’s obligations in respect of this Transaction and any such designee may assume such obligations, and Party A shall be discharged of its obligations to Party B solely to the extent of any such performance.

Matters Relating to Agent:

Morgan Securities Inc., as agent, (the “Agent”) acts solely as agent on a disclosed basis with respect to the transactions contemplated hereunder, and (ii) the Agent has no obligation, by guaranty, endorsement or otherwise, with respect to the obligations of either Party B or Party A hereunder, either with respect to the delivery of cash or Shares, either at the beginning or the end of the transactions contemplated hereby. In this regard, each of Party A and Party B acknowledges and agrees to look solely to the other for performance hereunder, and not to the Agent.

Notwithstanding any other provisions hereof, Party A shall not be entitled to receive Shares hereunder (whether in connection with the purchase of Shares on any Settlement Date or any Termination Settlement Date, any Private Placement Settlement or otherwise) to the extent (but only to the extent) that after such receipt (a) Party A’s ultimate parent entity would, directly or indirectly, beneficially own (as such term is defined for purposes of Section 13(d) of the Exchange Act) in excess of 8.0% of the outstanding Shares or (b) Party A’s ultimate parent entity would purchase, acquire or take (as such terms are used in the Federal Power Act) at any time on the relevant date in excess of 8.0% of the outstanding Shares. Any purported delivery of Shares by Party B hereunder shall be void and have no effect to the extent (but only to the extent) that after receipt of such Shares by Party A, Party A’s ultimate parent entity would, directly or indirectly, individually or in the aggregate, so beneficially own, or purchase, acquire or take, as applicable, in excess of 8.0% of the outstanding Shares. If, on any day, any delivery of Shares by Party B is not effected, in whole or in part, as a result of this provision, Party B’s obligation to make such delivery shall not be extinguished, and Party B shall make such delivery as promptly as practicable after, but in no event within one Exchange Business Day after, Party A gives notice to Party B that after receipt of such delivery, Party A’s ultimate parent entity would not, directly or indirectly, individually or in the aggregate, beneficially own, or purchase, acquire or take, as applicable, in excess of 8.0% of the outstanding Shares.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

(i) If Party B delivers the Restricted Shares pursuant to this clause (i) (a “Private Placement Settlement”), then delivery of Restricted Shares by Party B shall be effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Party A; provided that if, on or before the date that a Private Placement Settlement would occur, Party B has taken, or caused 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 Party B to Party A (or any affiliate designated by Party A) of the Restricted Shares or the exemption pursuant to Section 4(1) or Section 4(3) of the Securities Act for resales of the Restricted Shares by Party A (or any such affiliate of Party A) or Party B fails to deliver the Restricted Shares when due or otherwise fails to perform obligations within its control in respect of a Private Placement Settlement, it shall be an Event of Default with respect to Party B and Section 6 of the Agreement shall apply. The Private Placement Settlement of such Restricted Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Party A, due diligence rights (for Party A or any designated buyer of the Restricted Shares by Party A), opinions and certificates, and such other documentation as is customary for private placement agreements, all reasonably acceptable to Party A. In the case of a Private Placement Settlement, Party A shall, in its good faith discretion, adjust the amount of Restricted Shares to be delivered to Party A hereunder in a commercially reasonable manner to reflect the fact that such Restricted Shares may not be freely returned to securities lenders by Party A and may only be saleable by Party A at a discount to reflect the lack of liquidity in Restricted Shares. Notwithstanding the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Clearance System Business Day following notice by Party A to Party B of the number of Restricted Shares to be delivered pursuant to this clause (i). For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be due on the Settlement Date or Termination Settlement Date that would otherwise be applicable.

(ii) If Party B delivers any Restricted Shares in respect of the Transaction, Party B agrees that (i) such Shares may be transferred by and among JPMorgan Chase Bank, National Association 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, Party B shall 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 Party A (or such affiliate of Party A) to Party B or such transfer agent of seller’s and broker’s representation letters customarily delivered by Party A or its affiliates 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 Party A (or such affiliate of Party A).
