(viii) The representations and warranties of Issuer set forth in Section 3 of the Agreement and Section 1 of the Purchase Agreement (the “Purchase Agreement”) dated as of March 13, 2012 between Issuer and Merrill Lynch, Pierce, Fenner & Smith Incorporated as representative of the Initial Purchasers party thereto are true and correct and are hereby deemed to be repeated to Dealer as if set forth herein.

(ix) Issuer understands no obligations of Dealer to it hereunder will be entitled to the benefit of deposit insurance and that such obligations will not be guaranteed by any Affiliate of Dealer or any governmental agency.

(x) During the period starting on the first Expiration Date and ending on the last Expiration Date (the “Settlement Period”), the Shares and any securities that are convertible into, or exchangeable or exercisable for, Shares will not be subject to a “restricted period,” as such term is defined in Regulation M under the Exchange Act.

(xi) On each day during the Settlement Period, neither Issuer nor any “affiliate” or “affiliated purchaser” (each as defined in Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by means of any cash-settled or other derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an 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 or exercisable for Shares, except through Dealer; provided that the foregoing shall not limit Issuer’s ability, pursuant to any plan (as defined in Rule 10b-18) of Issuer, to re-acquire Shares in connection with any equity transaction related to such plan or limit Issuer’s ability to withhold Shares to cover tax liabilities associated with such equity transactions or otherwise restrict Issuer’s ability to repurchase Shares under privately negotiated transactions with any of its employees, officers, directors or affiliates, so long as any re-acquisition, withholding or repurchase does not constitute a “Rule 10b-18 purchase” (as defined in Rule 10b-18).

(xiii) Issuer is not aware of any state, local (including non-U.S. jurisdictions) or non-U.S. federal law, rule, regulation or regulatory order applicable to the Shares that would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of Dealer or its affiliates owning or holding (however defined) Shares.

(b) Each of Dealer and Issuer agrees and represents that it is an “eligible contract participant” as defined in the U.S. Commodity Exchange Act, as amended.

(c) Each of Dealer and Issuer acknowledges that the offer and sale of the 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(2) thereof.

The parties hereto further agree and acknowledge that it is the intent of the parties that (A) this Confirmation is (i) a “securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment

9

amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “settlement payment,” within the meaning of Section 546 of the Bankruptcy Code and (ii) a “swap agreement,” as such term is defined in Section 101(53B) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer,” as such term is defined in Section 101(54) of the Bankruptcy Code and a “payment or other transfer of property” within the meaning of Sections 362 and 546 of the Bankruptcy Code, (B) the Agreement is a “master netting agreement” and each of the parties thereto is a “master netting agreement participant”, each as defined in the Bankruptcy Code, (C) a party’s right to liquidate a Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the other party to constitute a “contractual right … to cause the liquidation, termination or acceleration” of the Transaction as described in the Bankruptcy Code and (D) Dealer is entitled to the protections afforded by, among other sections, Sections 362(b)(6), 362(b)(17), 362(b)(27), 362(o), 546(e), 546(g), 546(j), 548(d)(2), 555, 560 and 561 of the Bankruptcy Code.

8. Other Provisions:

(a) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If Issuer shall owe Dealer any amount pursuant to Sections 12.2, 12.3, 12.6, 12.7 or 12.9 of the Equity Definitions or pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Issuer shall have the right, in its sole discretion, to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 9:30 A.M. New York City time on the Merger Date, Tender Offer Date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of another Extraordinary Event, as applicable (“Notice of Share Termination”); provided that if Issuer does not elect to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to elect to require Issuer to satisfy its Payment Obligation by the Share Termination Alternative, notwithstanding Issuer’s failure to elect or election to the contrary; and provided further that Issuer shall not have the right to so elect (but, for the avoidance of doubt, Dealer shall have the right to so elect) in the event of (i) an Insolvency, a Nationalization, a Tender Offer or a Merger Event, in each case, in which the consideration or proceeds to be paid to holders of Shares consists solely of cash or (ii) an Event of Default in which Issuer is the Defaulting Party or a Termination Event in which Issuer is the Affected Party, which Event of Default or Termination Event resulted from an event or events within Issuer’s control. Upon such Notice of Share Termination, the following provisions shall apply on the Scheduled Trading Day immediately following the Merger Date, the Tender Offer Date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of another Extraordinary Event, as applicable:

10

(b) Private Placement Procedures. (i) If, in the reasonable judgment of Dealer, for any reason, any Shares or any securities of Issuer or its affiliates comprising any Share Termination Delivery Units deliverable to Dealer hereunder (any such Shares or securities, “Delivered Securities”) would not be immediately freely transferable by Dealer under Rule 144 under the Securities Act, then the provisions set forth in this Section 8(b) shall apply. In such event, Issuer shall deliver additional Delivered Securities so that the value of such Delivered Securities, as determined by the Calculation Agent to reflect an appropriate liquidity discount, equals the value of the number of Delivered Securities that would otherwise be deliverable if such Delivered Securities were freely tradeable (without prospectus delivery) upon receipt by Dealer (such value, the “Freely Tradeable Value”). (For the avoidance of doubt, as used in this paragraph (b) only, the term “Issuer” shall mean the issuer of the relevant securities, as the context shall require.)

(ii) (A) Dealer (or an Affiliate of Dealer designated by Dealer) and any potential institutional purchaser of any such Delivered Securities from Dealer or such Affiliate identified by Dealer shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation in compliance with applicable law with respect to Issuer customary in scope for 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);

(B) Dealer (or an Affiliate of Dealer designated by Dealer) and Issuer shall enter into an agreement (a “Private Placement Agreement”) on commercially reasonable terms in connection with the private placement of such Delivered Securities by Issuer to Dealer or such Affiliate and the private resale of such Delivered Securities by Dealer or such Affiliate, substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance commercially reasonably satisfactory to Dealer and Issuer, which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating to the indemnification of, and contribution in connection with the liability of, Dealer and its Affiliates and Issuer, shall provide for the payment by Issuer of all reasonable expenses in connection with such resale, including all reasonable fees and expenses of counsel for Dealer, shall contain representations, warranties and agreements of Issuer 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 shall use best efforts to provide for the delivery of accountants’ “comfort letters” to Dealer or such Affiliate with respect to the financial statements and certain financial information contained in or incorporated by reference into the offering memorandum prepared for the resale of such Shares; and

(C) Issuer agrees that any Delivered Securities so delivered to Dealer, (i) may, assuming compliance with applicable securities laws, be transferred by and among Dealer and its Affiliates, and Issuer shall effect such transfer without any further action by Dealer and (ii) after the minimum “holding period”

11

within the meaning of Rule 144(d) under the Securities Act has elapsed with respect to such Delivered Securities, Issuer shall promptly remove, or cause the transfer agent for such Shares or securities to remove, any legends referring to any such restrictions or requirements from such Delivered Securities upon delivery by Dealer (or such Affiliate of Dealer) to Issuer or such transfer agent of any seller’s and broker’s representation letters customarily delivered by Dealer in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, 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).

(D) Neither Dealer nor Issuer shall 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 Issuer to Dealer (or any affiliate designated by Dealer) of the Shares or Share Termination Delivery Units, as the case may be, or the exemption pursuant to Section 4(1) or Section 4(3) of the Securities Act for resales of the Shares or Share Termination Delivery Units, as the case may be, by Dealer (or any such affiliate of Dealer).

(c) Make-whole. Dealer or its affiliate may sell such Shares or Share Termination Delivery Units, as the case may be, during a period (the “Resale Period”) commencing on the Scheduled Trading Day following delivery of such Shares or Share Termination Delivery Units, as the case may be, and ending on the Scheduled Trading Day on which Dealer completes the sale of all such Shares or Share Termination Delivery Units, as the case may be, or a sufficient number of Shares or Share Termination Delivery Units, as the case may be, so that the realized net proceeds of such sales exceed the Freely Tradeable Value (such amount of the Freely Tradeable Value, the “Required Proceeds”). If any of such delivered Shares or Share Termination Delivery Units remain after such realized net proceeds exceed the Required Proceeds, Dealer shall return such remaining Shares or Share Termination Delivery Units to Issuer. If the Required Proceeds exceed the realized net proceeds from such resale, Issuer shall transfer to Dealer by the open of the regular trading session on the Exchange on the Scheduled Trading Day immediately following the last day of the Resale Period the amount of such excess (the “Additional Amount”) in cash or in a number of additional Shares or Share Termination Delivery Units, as the case may be, (“Make-whole Shares”) in an amount that, based on the Relevant Price on the last day of the Resale Period (as if such day was the “Valuation Date” for purposes of computing such Relevant Price), has a dollar value equal to the Additional Amount. The Resale Period shall continue to enable the sale of the Make-whole Shares in the manner contemplated by this Section 8(c). This provision shall be applied successively until the Additional Amount is equal to zero, subject to Section 8(e).

(d) Beneficial Ownership. Notwithstanding anything to the contrary in the Agreement or this Confirmation, in no event shall Dealer be entitled to receive, or shall be deemed to receive, any Shares in connection with this Transaction if, immediately upon giving effect to such receipt of such Shares, (i) Dealer’s Beneficial Ownership would be equal to or greater than 7.5% of the outstanding Shares, (ii) Dealer, or any “affiliate” or “associate” of Dealer, would be an “interested stockholder” of Issuer, as all such terms are defined in Section 203 of the Delaware General Corporation Law or (iii) Dealer, Dealer Group (as defined below) 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 any federal, state or local (including non-U.S.) laws, regulations, regulatory orders or organizational documents or contracts of Issuer that are, in each case, applicable to ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number of Shares equal to (x) the number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval by a local, state, federal or non-U.S. regulator) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under Applicable Laws, as determined by Dealer in its commercially reasonable discretion, 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 Issuer or any contract or agreement to which Issuer is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination (each of clause (i), (ii) and (iii) above, an “Ownership Limitation”). If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of an Ownership Limitation, Dealer’s right to receive such delivery shall not be extinguished and Issuer shall make such delivery as promptly as practicable after, but in no event later than one Scheduled Trading Day after, Dealer gives notice to Issuer that such delivery would not result in any of such Ownership Limitations being breached. “Dealer’s Beneficial Ownership” means the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and the rules promulgated thereunder (collectively, “Section 13”)) of Shares, without duplication, by Dealer, together with any of its affiliates or other person subject to aggregation with Dealer under Section 13 for purposes of “beneficial ownership”, or by any “group” (within the meaning of Section 13) of which Dealer is or may be deemed to be a part (Dealer and any such affiliates, persons and groups, collectively,

12

“Dealer Group”) (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such number). Notwithstanding anything in the Agreement or this Confirmation to the contrary, Dealer (or the affiliate designated by Dealer pursuant to Section 8(l) below) shall not become the record or beneficial owner, or otherwise have any rights as a holder, of any Shares that Dealer (or such affiliate) is not entitled to receive at any time pursuant to this Section 8(d), until such time as such Shares are delivered pursuant to this Section 8(d).

(e) Limitations on Settlement by Issuer.

(i) Notwithstanding anything herein or in the Agreement to the contrary, in no event shall Issuer be required to deliver Shares in connection with the Transaction in excess of the Capped Number of Shares (as provided in Annex A to this Confirmation), subject to adjustment from time to time in accordance with the provisions of this Confirmation or the Definitions resulting from actions of Issuer or events within Issuer’s control (the “Capped Number”). Issuer 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 of the Issuer 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 Issuer shall not have delivered the full number of Shares otherwise deliverable as a result of this Section 8(e) (the resulting deficit, the “Deficit Shares”), Issuer shall be continually obligated to deliver, from time to time until the full number of Deficit Shares have been delivered pursuant to this paragraph, Shares when, and to the extent, that (x) Shares are repurchased, acquired or otherwise received by Issuer or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (y) authorized and unissued Shares reserved for issuance in respect of other transactions prior to such date which prior to the relevant date become no longer so reserved or (z) Issuer additionally authorizes any unissued Shares that are not reserved for other transactions. Issuer shall immediately notify Dealer of the occurrence of any of the foregoing events (including the number of Shares subject to clause (x), (y) or (z) and the corresponding number of Shares to be delivered) and promptly deliver such Shares thereafter.

(ii) Issuer shall not enter into any transaction, or take any other action, that would result in an adjustment to the maximum number of Shares deliverable under clause (i) of this subsection that would result in the issuance of a number of Shares that would require stockholder approval under the continued listing standards of the Exchange without having obtained prior stockholder approval.

(f) Right to Extend. Dealer may postpone any Exercise Date or Settlement Date or any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which event the Calculation Agent shall make appropriate adjustments to the Number of Shares to be Delivered with respect to one or more Components), such postponement or extension not to exceed 20 Scheduled Trading Days in the aggregate, if Dealer determines, in its commercially reasonable discretion, that such extension is reasonably necessary or appropriate to (i) preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions in the cash market, the stock loan market or any other relevant market or (ii) to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Issuer or an affiliated purchaser of Issuer, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.

(g) Equity Rights. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights with respect to the Transaction that are senior to the claims of common stockholders in the event of Issuer’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during Issuer’s bankruptcy to any claim arising as a result of a breach by Issuer of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that this Confirmation is not secured by any collateral that would otherwise secure the obligations of Issuer herein under or pursuant to any other agreement.

(h) Amendments to Equity Definitions. The following amendments shall be made to the Equity Definitions:

(i) Section 11.2(a) of the Equity Definitions is hereby amended by deleting the words “diluting or concentrative” and replacing them with the word “material”; and adding the phrase “or Warrants” at the end of the sentence.

13

(ii) The first sentence of Section 11.2(c) of the Equity Definitions, prior to clause (A) thereof, is hereby amended to read as follows: ‘(c) If “Calculation Agent Adjustment” is specified as the Method of Adjustment in the related Confirmation of a Share Option Transaction, then following the announcement or occurrence of any Potential Adjustment Event, the Calculation Agent will determine whether such Potential Adjustment Event has a material effect on the theoretical value of the relevant Shares or options on the Shares and, if so, will (i) make appropriate adjustment(s), if any, to any one or more of:’ and, the portion of such sentence immediately preceding clause (ii) thereof is hereby amended by deleting the words “diluting or concentrative” and the words “(provided that no adjustments will be made to account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares)” and replacing such latter phrase with the words “(and, for the avoidance of doubt, adjustments may be made to account solely for changes in volatility, expected dividends, stock loan rate or liquidity relative to the relevant Shares)”;

(iii) Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words “may have a diluting or concentrative” and replacing them with “is the result of a corporate event involving the Issuer that might have a material” and adding the phrase “or Warrants” at the end of the sentence;

(iv) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) at Dealer’s option, the occurrence of any of the events specified in Section 5(a)(vii) (1) through (9) of the ISDA 2002 Master Agreement with respect to that Issuer, provided that the period for dismissal, discharge, stay or restraint therein shall be increased from within 15 days to within 60 days.”;

(v) Section 12.9(b)(iv) of the Equity Definitions is hereby amended by (A) deleting (1) subsection (A) in its entirety, (2) the phrase “or (B)” following subsection (A) and (3) the phrase “in each case” in subsection (B); (B) replacing “will lend” with “lends” in subsection (B); and (C) deleting the phrase “neither the Non-Hedging Party nor the Lending Party lends Shares in the amount of the Hedging Shares or” in the penultimate sentence; and

(vi) Section 12.9(b)(v) of the Equity Definitions is hereby amended by (A) adding the word “or” immediately before subsection “(B)” and deleting the comma at the end of subsection (A); and (B)(1) deleting subsection (C) in its entirety, (2) deleting the word “or” immediately preceding subsection (C) and (3) replacing in the penultimate sentence the words “either party” with “the Hedging Party” and (4) deleting clause (X) in the final sentence.

(i) Transfer and Assignment. Dealer may transfer or assign its rights and obligations hereunder and under the Agreement, in whole or in part, at any time to any person or entity whatsoever without the consent of Issuer. At any time at which any Ownership Limitation or a Hedging Disruption exists, if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party after using its commercially reasonable efforts on pricing terms and within a time period reasonably acceptable to Dealer such that an Ownership Limitation or a Hedging Disruption, as the case may be, no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of the Transaction, such that such Ownership Limitation or Hedging Disruption, as the case may be, no longer exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment or delivery shall be made pursuant to Section 6 of the Agreement and Section 8(b) of this Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the Transaction, (ii) Issuer shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction shall be the only Terminated Transaction.

(j) Adjustments. For the avoidance of doubt, whenever the Calculation Agent is called upon to make an adjustment pursuant to the terms of this Confirmation or the Definitions to take into account the effect of an event, the Calculation Agent shall make such adjustment by reference to the effect of such event on the Hedging Party, assuming that the Hedging Party maintains a commercially reasonable hedge position.

(k) Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Issuer and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to Issuer relating to such tax treatment and tax structure.

(l) Designation by Dealer. 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 Issuer, Dealer

14

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 Issuer to the extent of any such performance.

(m) Additional Termination Events. The occurrence of any of the following shall constitute an Additional Termination Event with respect to which the Transaction shall be the sole Affected Transaction and Issuer shall be the sole Affected Party; provided that with respect to any Additional Termination Event, Dealer may choose to treat part of the Transaction as the sole Affected Transaction, and, upon the termination of the Affected Transaction, a Transaction with terms identical to those set forth herein except with a Number of Warrants equal to the unaffected number of Warrants shall be treated for all purposes as the Transaction, which shall remain in full force and effect:

(i) Dealer reasonably determines that it is advisable to terminate a portion of the Transaction so that Dealer’s related hedging activities will comply with applicable securities laws, rules or regulations or related policies and procedures of Dealer (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer);

(ii) any “person” or “group” within the meaning of Section 13(d) of the Exchange Act, other than Issuer or its subsidiaries, files a Schedule TO or any schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect ultimate “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of Issuer’s common equity representing more than 50% of the voting power of Issuer’s common equity;

(iii) consummation of any binding share exchange, exchange offer, tender offer, consolidation or merger of Issuer pursuant to which the Shares will be converted into cash, securities or other property or any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of Issuer and its subsidiaries, taken as a whole, to any person other than one or more of Issuer’s subsidiaries (any such exchange, offer, consolidation, merger, transaction or series of transactions, an “Event”); provided, however, that any such Event where the holders of more than 50% of the Shares immediately prior to such Event, own, directly or indirectly, more than 50% of all classes of the common equity of the continuing or surviving person or transferee or the parent thereof immediately after such event shall not be an Additional Termination Event;

(iv) at any time Issuer’s Continuing Directors (as defined below) cease to constitute at least a majority of Issuer’s board of directors;
