Counterparty has all necessary corporate power and authority to execute, deliver and perform its obligations in respect of this Transaction; such execution, delivery and performance have been duly authorized by all necessary corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar

laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.

Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than 69,620,000 (in the case of the first such notice) or (ii) thereafter more than 745,000 less than the number of Shares included in the immediately preceding Repurchase Notice. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to this Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify

Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Party at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of this Transaction.

Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as defined in the Internal Revenue Code of 1986, as amended (the “Code” and such person, a “Transferee”); provided that any Transfer Options may be transferred or assigned to any wholly-owned subsidiary of Counterparty that is a disregarded entity for purposes of the Code. For the avoidance of doubt, in the event Dealer determines that any withholding tax is required to be imposed on payments by Dealer to a Transferee because such Transferee is not then a United States person within the meaning of the Code, Dealer will withhold and pay over the amount of such tax, which shall be deemed received by such Transferee, and Dealer will not gross such Transferee up for any such amounts. Moreover, if any such withholding tax liability is

asserted against Dealer, then Counterparty and such Transferee shall indemnify and hold harmless Dealer and its affiliates from and against any and all losses, claims, damages, judgments, liabilities and expenses (including, without limitation, interest, penalties and attorney fees) resulting therefrom;

Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights or obligations under the Transaction to any third party with a rating for its long term, unsecured and unsubordinated indebtedness equal to or better than the lesser of (x) the credit rating of Dealer at the time of the transfer and (y) A- by Standard and Poor’s Rating Group, Inc. or its successor (“S&P”), or A3 by ▇▇▇▇▇’▇ Investor Service, Inc. (“Moody’s”) or, if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a Terminated Portion, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section 9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator

of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or contract that is 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 of under the Applicable Laws, as determined by Dealer in its reasonable discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or would result in an adverse effect on a Dealer Person, under the Applicable Laws, as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.

Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If in respect of this Transaction, an amount is payable by Dealer to Counterparty (i) pursuant to Section 12.7 or Section 12.9 of the Equity Definitions or (ii) pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Counterparty may request Dealer to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) (except that Counterparty shall not make such an election in the event of a Nationalization, Insolvency, Merger Event or Tender Offer, in each case, in which the consideration to be paid to holders of Shares consists solely of cash, or an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party, other than an Event of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the type described in Section 5(b) of the Agreement in each case that resulted from an event or events outside Counterparty’s control) and shall give irrevocable

telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York City time) on the Merger Date, the Tender Offer Date, the Announcement Date (in the case of Nationalization, Insolvency or Delisting), the Early Termination Date or date of cancellation, as applicable; provided that if Counterparty does not validly request Dealer to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to satisfy its Payment Obligation by the Share Termination Alternative, notwithstanding Counterparty’s election to the contrary. In calculating any amounts under Section 6(e) of the Agreement, notwithstanding anything to the contrary in the Agreement, (1) separate amounts shall be calculated as set forth in Section 6(e) with respect to (i) this Transaction and (ii) all other Transactions, and (2) such separate amounts shall be payable pursuant to Section 6(d)(ii) of the Agreement.

Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are

senior to the claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to the Transaction; provided, further, that nothing herein shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

Payment by Counterparty. In the event that (i) an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event of Default (other

than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section 12.7 or Section 12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be zero.
