Opening Transaction

Ladies and Gentlemen:

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced transaction entered into on the Trade Date specified below (the “Transaction”) between Citibank, N.A. (“Dealer”) and MF Global Holdings Ltd. (“Issuer”). This communication constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.

1. This Confirmation is subject to, and incorporates, the definitions and provisions of the 2006 ISDA Definitions (the “2006 Definitions”) and the definitions and provisions of the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”, and together with the 2006 Definitions, the “Definitions”), in each case as published by the International Swaps and Derivatives Association, Inc. (“ISDA”). In the event of any inconsistency between the 2006 Definitions and the Equity Definitions, the Equity Definitions will govern. For purposes of the Equity Definitions, each reference herein to a Warrant shall be deemed to be a reference to a Call Option or an Option, as context requires.

Each party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation relates on the terms and conditions set forth below.

This Confirmation evidences a complete and binding agreement between Dealer and Issuer as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall be subject to an agreement (the “Agreement”) in the form of the 1992 ISDA Master Agreement (Multicurrency—Cross Border) as if Dealer and Issuer had executed an agreement in such form on the date hereof (but without any Schedule except for (i) the election of Loss and Second Method and US Dollars (“USD”) as the Termination Currency, (ii) the replacement of the word “third” in the last line of Section 5(a)(i) of the Agreement with the word “first” and (iii) the election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Issuer with the words “, or becoming capable at such time of being declared,” deleted from clause (1) of Section 5(a)(vi), with a “Threshold Amount” of USD50 million). In addition, Section 5(a)(i) of the Agreement shall be amended by adding at the end of such section the following: “Notwithstanding the foregoing, a default under this Section 5(a)(i) shall not constitute an Event of Default if (x) the default was caused solely by error or omission of an administrative or operational nature; (y) funds were available to enable the party to make the payment when due and (z) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay.”

All provisions contained in, or incorporated by reference to, the Agreement will govern this Confirmation except as expressly modified herein. In the event of any inconsistency between this Confirmation and either the Definitions or the Agreement, this Confirmation shall govern.

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

(viii) The representations and warranties of Issuer set forth in Section 3 of the Agreement and Section 1 of the Underwriting Agreement dated as of February 7, 2011, between Issuer and Goldman, Sachs & Co., Citigroup Global Markets Inc. and Deutsche Bank Securities Inc., as representatives of the several Underwriters listed in Schedule A thereto (the “Underwriting Agreement”), are true and correct as of the Trade Date and the Effective Date and are hereby deemed to be repeated to Dealer as if set forth herein.

(ix) During the period starting on the first Expiration Date and ending on the last Expiration Date (the “Settlement Period”), (A) the Shares or securities that are convertible into, or exchangeable or exercisable for Shares, shall not be subject to a “restricted period,” as defined in Regulation M under the Exchange Act (“Regulation M”) and (B) Issuer shall not engage in any “distribution,” as such term is defined in Regulation M, other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M, until the second Exchange Business Day immediately following the Settlement Period.

(x) During the Settlement Period and on any other Exercise Date, neither Issuer nor any “affiliate” or “affiliated purchaser” (each as defined in Rule 10b-18 of 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 such restrictions will not apply to the following: (A) privately negotiated off-market purchases of Shares (or any security convertible into or exchangeable for Shares), (B) purchases of Shares pursuant to exercises of stock options granted to former or current employees, officers, directors, independent contractors or other affiliates of Issuer, including the withholding and/or purchase of Shares from holders of such options to satisfy payment of the option exercise price and/or to satisfy tax withholding requirements in connection with the exercise of such options; (C) purchases of Shares from holders of performance shares or units or restricted shares or units to satisfy tax withholding requirements in connection with vesting; (D) the conversion or exchange by holders of any convertible or exchangeable securities of the Issuer issued prior to the Trade Date pursuant to the terms of such securities; or (E) purchases of Shares effected by or for a plan by an agent independent of the Issuer that satisfy the requirements of Rule 10b-18(a)(13)(ii).

13

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

(xii) Any Shares issued or delivered in connection with the Transaction shall be duly authorized and validly issued, fully paid and non-assessable, and the issuance or delivery thereof shall not be subject to any preemptive or similar rights and shall, upon issuance, be accepted for listing or quotation on the Exchange. The Shares of Issuer initially issuable upon exercise of the Warrants have been reserved for issuance by all required corporate action of the Issuer.

(xiii) No state, local or foreign law, rule, regulation or regulatory order applicable to the Shares 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, holding (however defined) or having a right to acquire Shares.

(b) Each of Dealer and Issuer agrees and represents that it is an “eligible contract participant” as defined in Section 1a(12) of the U.S. Commodity Exchange Act, as amended, and is entering into the Transaction as principal (and not as agent or in any other capacity, fiduciary or otherwise) and not for the benefit of any third party.

(c) Each of Dealer and Issuer acknowledges that the offer and sale of the Transaction to Dealer 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. Accordingly, Dealer represents and warrants to Issuer that (i) it has the financial ability to bear the economic risk of its investment in the Transaction and is able to bear a total loss of its investment and its investments in and liabilities in respect of the Transaction, which it understands are not readily marketable, are not disproportionate to its net worth, and it is able to bear any loss in connection with the Transaction, including the loss of its entire investment in the Transaction, (ii) it is an “accredited investor” as that term is defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a view to the distribution or resale thereof, (iv) the assignment, transfer or other disposition of the Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state securities laws, and (v) its financial condition is such that it has no need for liquidity with respect to its investment in the Transaction and no need to dispose of any portion thereof to satisfy any existing or contemplated undertaking or indebtedness and is capable of assessing the merits of and understanding (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and risks of the Transaction.

(d) Dealer represents to Issuer, and Issuer agrees and acknowledges, that Dealer is a “financial institution,” “swap participant” and “financial participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of Title 11 of the United States Code (the “Bankruptcy Code”). The parties hereto further agree and acknowledge (A) that 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 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” within the meaning of Section 546 of

14

the Bankruptcy Code, and (B) that 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.

(e) As a condition to the effectiveness of the Transaction, Issuer shall deliver to Dealer (i) an incumbency certificate, dated as of the Trade Date, of Issuer in customary form and (ii) an opinion of counsel, dated as of the Trade Date, and reasonably acceptable to Dealer in form and substance, with respect to matters set forth in clauses (i) through (iv) of Section 3(a) of the Agreement and the second sentence of Section 7(a)(xii) of this Confirmation as well as the execution and delivery of this Confirmation, limited to the U.S. federal and New York state law, subject to customary qualification and exceptions.

(f) Issuer understands that 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.

(a) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If Issuer shall owe Dealer any amount pursuant to Section 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 relevant Merger Date, Announcement Date (as a result of a Merger Event, Tender Offer, Nationalization, Insolvency or Delisting), Early Termination Date or date of cancellation or termination in respect of an 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 commercially reasonable 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, the Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable:

15

(b) Registration/Private Placement Procedures. (i) With respect to the Transaction, the following provisions shall apply to the extent provided for above opposite the caption “Net Share Settlement” in Section 2 or in paragraph (a) of this Section 8. If so applicable and the Shares or Share Termination Delivery Units, as the case may be, at such time may not be sold by Dealer without restriction or limitation under Rule 144 under the Securities Act or otherwise, then, at the election of Issuer by notice to Dealer within two Exchange Business Days after the relevant delivery obligation arises, but in any event at least one Exchange Business Day prior to the date on which such delivery obligation is due, either (A) all Shares or Share Termination Delivery Units, as the case may be, delivered by Issuer to Dealer shall be, at the time of such delivery, covered by an effective registration statement of Issuer for immediate resale by Dealer (such registration statement and the corresponding prospectus (the “Prospectus”) (including, without limitation, any sections describing the plan of distribution) in form and content commercially reasonably satisfactory to Dealer) or (B) Issuer shall deliver additional Shares or Share Termination Delivery Units, as the case may be, so that the value of such Shares or Share Termination Delivery Units, as determined by the Calculation Agent to reflect an appropriate liquidity discount, equals the value of the number of Shares or Share Termination Delivery Units that would otherwise be deliverable if such Shares or Share Termination Delivery Units were freely tradeable (without prospectus delivery) upon receipt by Dealer (such value, the “Freely Tradeable Value”); provided that, if requested by Dealer, Issuer shall make the election described in this clause (B) with respect to Shares delivered on all Settlement Dates no later than one Exchange Business Day prior to the first Exercise Date, and the applicable procedures described below shall apply to all Shares delivered on the Settlement Dates on an aggregate basis. (For the

16

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) If Issuer makes the election described in clause (b)(i)(A) above:

(A) Dealer (or an affiliate of Dealer designated by Dealer) shall be afforded a reasonable opportunity to conduct a due diligence investigation with respect to Issuer that is customary in scope for underwritten offerings of equity securities and that yields results that are commercially reasonably satisfactory to Dealer or such affiliate, as the case may be, in its discretion; and

(B) Dealer (or an affiliate of Dealer designated by Dealer) and Issuer shall enter into an agreement (a “Registration Agreement”) on commercially reasonable terms in connection with the public resale of such Shares or Share Termination Delivery Units, as the case may be, by Dealer or such affiliate substantially similar to underwriting agreements customary for underwritten offerings of equity securities of similar size, in form and substance commercially reasonably satisfactory to Dealer or such affiliate and Issuer, which Registration Agreement shall include, without limitation, provisions substantially similar to those contained in such underwriting 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 expenses in connection with such resale, including all registration costs and all reasonable fees and expenses of counsel for Dealer, and shall provide for the delivery of customary 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 Prospectus.

(iii) If Issuer makes the election described in clause (b)(i)(B) above:

(A) Dealer (or an affiliate of Dealer designated by Dealer) and any potential institutional purchaser of any such Shares or Share Termination Delivery Units, as the case may be, 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), subject to execution by such recipients of customary confidentiality agreements reasonably acceptable to Issuer;

(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 Shares or Share Termination Delivery Units, as the case may be, by Issuer to Dealer or such affiliate and the private resale of such shares 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 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 commercially reasonable efforts to provide for the delivery of customary 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;

(C) Issuer agrees that any Shares or Share Termination Delivery Units so delivered to Dealer, (i) may 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” within the meaning of Rule 144(d) under the Securities Act has elapsed with respect to such

17

Shares or any securities issued by Issuer comprising such Share Termination Delivery Units, 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 Shares or 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); and

(D) Issuer may not make the election described in this clause (b) if, on the date of its election, it 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 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 Shares. If Issuer makes the election described in clause (i)(B) of paragraph (b) of this Section 8, then Dealer or its affiliate may sell (which sale shall be made in a commercially reasonable manner) such Shares or Share Termination Delivery Units, as the case may be, during a period (the “Resale Period”) commencing on the Exchange Business Day following delivery of such Shares or Share Termination Delivery Units, as the case may be, and ending on the Exchange Business Day on which Dealer or its affiliate 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. If any of such delivered Shares or Share Termination Delivery Units remain after such realized net proceeds exceed the Freely Tradeable Value, Dealer shall return such remaining Shares or Share Termination Delivery Units to Issuer. If the Freely Tradeable Value exceeds 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 Exchange 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 if, immediately upon giving effect to such receipt of such Shares, (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 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 9.0% or more of the outstanding Shares on the date of determination 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 or other federal, state or local 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 number of Shares that would give rise to reporting (other than on Schedule 13D or 13G under the Exchange Act) or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Laws and with respect to which such requirements have not been met or the relevant approval has not been received or that would subject a Dealer Person to restrictions (including restrictions relating to business combinations and other designated transactions) under Applicable Laws minus (y)

18

1.0% of the number of Shares outstanding on the date of determination (any such condition described in clause (i) or (ii), an “Excess Ownership Position”). If any delivery owed to Dealer hereunder is not made, in whole or in part, as a result of this provision, Issuer’s obligation to make such delivery shall not be extinguished and Issuer shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, Dealer gives notice to Issuer that such delivery would not result in the existence of an Excess Ownership Position.

(e) Limitations on Settlement by Issuer. 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 lower of (i) 12,058,950 Shares (such number, as it may be adjusted from time to time in accordance with the provisions hereof, including the “Adjustment” provisions above, the “Capped Number”) and, (ii) so long as the Shareholder Approval (as defined below) has not been obtained, 7,105,221 (such number, as it may be adjusted from time to time in accordance with the provisions hereof and in accordance with the rules of the New York Stock Exchange, including the “Adjustment” provisions above, the “NYSE Capped Number”) (provided that Issuer shall promptly notify Dealer about any relevant change to such rules of which Issuer becomes aware). 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 would have otherwise been required to deliver Shares but shall not have delivered the full number of Shares deliverable as a result of the Capped Number defined in clause (i) above (the resulting deficit, the “Deficit Shares”), Issuer shall be continually 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 Issuer or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) 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 and (C) Issuer additionally authorizes any 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”). At any time that Issuer is obligated to deliver Deficit Shares, Issuer 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, deliver such Shares thereafter if permitted to do so without violating the rules of the New York Stock Exchange. Issuer shall not, until Issuer’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 or reserve any such Shares for future issuance for any purpose other than to satisfy Issuer’s obligations to Dealer under the Transaction. In addition, Issuer agrees to use its reasonable best efforts to obtain Shareholder Approval prior to December 31, 2012 to eliminate the NYSE Capped Number with respect to this Transaction (such approval, the “Shareholder Approval”). For the avoidance of doubt, “reasonable best efforts” for the purposes of the preceding sentence means, for each of Issuer’s regularly scheduled annual shareholder meetings occurring prior to December 31, 2012, putting forth such proposal on the official shareholder voting ballot, the board of directors of Issuer (the “Board of Directors”) recommending shareholders vote in favor of such proposal, and the Board of Directors supporting such proposal in the event of any potential opposition. Until such time that the Issuer obtains the Shareholder Approval, if as of any Settlement Date for any Component with respect to this Transaction, as a result of the application of the NYSE Capped Number, Issuer does not deliver to Dealer a number of Shares equal to the Number of Shares to be Delivered with respect to such Settlement Date or a number of Share Termination Delivery Units due on any date determined in accordance with Section 8(a) of this Confirmation, the Calculation Agent shall make an adjustment to the Strike Price, the Warrant Entitlement or any other term relevant to any outstanding Component of this Transaction, to account for such number of Shares or Share Termination Delivery Units not so delivered to Dealer, in order to allow Dealer to be made whole for any failure by Issuer to deliver any Shares or Share Termination Delivery Units with respect to the Number of Shares to be delivered or the number of Share Termination Delivery Units required to be delivered pursuant to Section 8(a) of this Confirmation, as the case may be, for any Component under this Transaction; provided

19

that the aggregate Number of Shares to be Delivered for all Settlement Dates will not be greater than the lower of (i) the Capped Number and (ii) the NYSE Capped Number.

(f) 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.

(i) 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.

(j) 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 and Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement and to determine the amount payable pursuant to Section 6(e) of the Agreement; 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, based on advice of counsel, 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), or Dealer, despite using commercially reasonable efforts, is unable or reasonably determines, based on advice of counsel, that it is impractical or illegal to hedge its obligations pursuant to this Transaction in the public market without registration under the Securities Act or as a result of any legal, regulatory or self-regulatory requirements;

(ii) at any time at which any Excess Ownership Position occurs, Dealer, in its discretion, is unable to effect a transfer or assignment to a third party of the Transaction or any other transaction between the parties after using its commercially reasonable efforts on pricing and terms and within a time period reasonably acceptable to Dealer such that an Excess Ownership Position no longer exists; provided that Dealer shall treat only that portion of the Transaction as the Affected Transaction as necessary so that such Excess Ownership Position no longer exists;

(iii) any Person or Group, other than Issuer or Issuer’s 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 of the Issuer’s common equity representing more than 50% of the voting power of the Issuer’s common equity;

(iv) the consummation of any consolidation, merger, amalgamation, scheme of arrangement or other binding share exchange or reclassification or similar transaction between Issuer and another person (other than Issuer’s subsidiaries), in each case pursuant to which the Shares shall be converted into cash, securities or other property, other than a transaction (A) that results in the holders of all classes of the Issuer’s common equity immediately prior to such transaction owning, directly or indirectly, as a result of such transaction, more than 50% of the surviving corporation or transferee or the parent thereof immediately after such event, or (B) effected solely to change the Issuer’s jurisdiction of incorporation or to form a holding company for the Issuer and that results in a share exchange or reclassification or similar exchange of the

21

outstanding Shares solely into common shares of the surviving entity or any sale or other disposition in one transaction or a series of transactions of all or substantially all of the assets of the Issuer and the Issuer’s subsidiaries, on a consolidated basis, to another person (other than any of the Issuer’s subsidiaries); or

(v) so long as Issuer does not obtain the Shareholder Approval described in Section 8(e) of this Confirmation, at any time during the period from and including the Trade Date, to and including the final Expiration Date, (x) the Number of Shares to be Delivered with respect to all Components of this Transaction that would be deliverable (determined as if such time were the Valuation Time, such date were the Exercise Date and Valuation Date for a number of Warrants equal to the Number of Warrants as of such date and Net Share Settlement applied) exceeds a number of Shares equal to 80% of the NYSE Capped Number or (y) Issuer makes a public announcement of any transaction or event that, in the reasonable opinion of Dealer would, upon consummation of such transaction or upon the occurrence of such event, as applicable, and after giving effect to any applicable adjustments hereunder, cause the Number of Shares to be Delivered with respect to all Components of this Transaction immediately following the consummation of such transaction or the occurrence of such event (determined as if the time immediately following the consummation of such transaction or the occurrence of such event were the Valuation Time, the date upon which such transaction is consummated or such event occurs were the Exercise Date and Valuation Date for a number of Warrants equal to the Number of Warrants as of such date and Net Share Settlement applied) to exceed a number of Shares equal to 80% of the NYSE Capped Number.

provided, however, that in the case of a transaction or event described in clause (iii) or (iv) above, if at least 90% of the consideration received or to be received by holders of the Shares (excluding cash payments for fractional Shares) in the transaction or transactions described in such clauses above consists of shares of common stock or common equity interests that are traded on a United States national or regional securities exchange or that will be so traded when issued or exchanged in connection with the transaction or transactions described in such clauses above, such transaction or transactions will not constitute an Additional Termination Event as a result of either clause (iii) or (iv) above.

Solely for the purposes of this Section 8(j), “Person” shall include any “person” within the meaning of Section 13(d) of the Exchange Act.

Solely for the purposes of this Section 8(j), “Group” shall include any “person” within the meaning of Section 13(d) of the Exchange Act.

Solely for the purposes of this Section 8(j), whether a Person is a “Beneficial Owner” of securities shall be defined under Rule 13d-3 of the Exchange Act.

(k) Effectiveness. If, on or prior to the Effective Date, Dealer reasonably determines that it is advisable to cancel the Transaction because of concerns that Dealer’s related hedging activities could be viewed as not complying with applicable securities laws, rules or regulations, the Transaction shall be cancelled and shall not become effective, and neither party shall have any obligation to the other party in respect of the Transaction.

(l) Unwind Calculation. In connection with any calculation of any amount pursuant to Section 6 of the Agreement or Section 12 of the Equity Definitions, for the avoidance of doubt, Dealer shall make any such calculations without taking into account the limitation set forth in clause (ii) of the first sentence of Section 8(e) of this Confirmation.

(m) Extension of Settlement. Dealer may divide any Component into additional Components and designate the Expiration Date and the Number of Warrants for each such Component if Dealer determines, in its reasonable discretion, that such further division is necessary or advisable to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions in the cash market or stock loan market or to enable Dealer to effect purchases of Shares in connection with its hedging activity hereunder in a manner that would, if Dealer were Issuer or an affiliated purchaser of

22

Issuer, based on advice of counsel, be in compliance with applicable legal, regulatory and self-regulatory requirements or with related policies and procedures applicable to Dealer.

(n) No Netting and Set-off. The provisions of Section 2(c) of the Agreement shall not apply to the Transaction. Each party waives any and all rights it may have to set-off delivery or payment obligations it owes to the other party under the Transaction against any delivery or payment obligations owed to it by the other party, whether arising under the Agreement, under any other agreement between parties hereto, by operation of law or otherwise.

(o) Delivery of Cash. For the avoidance of doubt, nothing in this Confirmation shall be interpreted as requiring the Issuer to deliver cash in respect of the settlement of the Transaction, except in circumstances where the required cash settlement thereof is permitted for classification of the contract as equity by ASC 815-40 (formerly EITF 00-19) as in effect on the relevant Trade Date (including, without limitation, where the Issuer so elects to deliver cash or fails timely to elect to deliver Shares or Share Termination Delivery Property in respect of such settlement).

(p) Governing Law. THE AGREEMENT, THIS CONFIRMATION AND ALL MATTERS ARISING IN CONNECTION WITH THE AGREEMENT AND THIS CONFIRMATION SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REFERENCE TO ITS CHOICE OF LAW DOCTRINE, OTHER THAN TITLE 14 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

(q) Amendment. This Confirmation and the Agreement may not be modified, amended or supplemented, except in a written instrument signed by Issuer and Dealer.

(r) Counterparts. This Confirmation may be executed in several counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

(s) 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, or make or receive any payment in cash, to or from Issuer, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations; provided that such designation shall not result in any additional costs or liabilities for Issuer. For the avoidance of doubt, Dealer hereby acknowledges that notwithstanding any such designation hereunder, to the extent any of Dealer’s obligations in respect of this Transaction are not completed by its designee, Dealer shall be obligated to continue to perform or to cause any other of its designees to perform in respect of such obligations.

9. Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party (i) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into the Transaction by, among other things, the mutual waivers and certifications provided herein.

10. Submission to Jurisdiction. Section 13(b) of the Agreement is deleted in its entirety and replaced by the following:

“Each party hereby irrevocably and unconditionally submits for itself and its property in any suit, legal action or proceeding relating to the Agreement and/or the Transaction, or for recognition and enforcement of any judgment in respect thereof, (each, “Proceedings”) to the exclusive jurisdiction of the Supreme Court of the State of New York, sitting in New York County, the courts of the United States of America for the Southern District of New York and appellate courts from any thereof. Nothing in this Confirmation or the Agreement precludes either party from bringing Proceedings in any other jurisdiction if (A) the courts of the State of New York or the United States of America for the Southern District of New York lack jurisdiction over the parties or the subject matter of the Proceedings or declines to accept the Proceedings on the grounds of lacking such jurisdiction; (B) the Proceedings are

23

commenced by a party for the purpose of enforcing against the other party’s property, assets or estate any decision or judgment rendered by any court in which Proceedings may be brought as provided hereunder; (C) the Proceedings are commenced to appeal any such court’s decision or judgment to any higher court with competent appellate jurisdiction over that court’s decisions or judgments if that higher court is located outside the State of New York or Borough of Manhattan, such as a federal court of appeals or the U.S. Supreme Court; or (D) any suit, action or proceeding has been commenced in another jurisdiction by or against the other party or against its property, assets or estate and, in order to exercise or protect its rights, interests or remedies under the Agreement or this Confirmation, the party (1) joins, files a claim, or takes any other action, in any such suit, action or proceeding, or (2) otherwise commences any Proceeding in that other jurisdiction as the result of that other suit, action or proceeding having commenced in that other jurisdiction.”

24

Issuer hereby agrees (a) to check this Confirmation carefully and promptly upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by Dealer) correctly sets forth the terms of the agreement between Dealer and Issuer with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and promptly returning an executed copy to Citibank, N.A., 333 West 34^th Street, 2^nd Floor, New York, New York 10001, Attention: Confirmation Unit.
