Dealer may postpone or add, in whole or in part, any Exercise Date or Settlement Date or any other date of valuation or delivery by Dealer, with respect to some or all of the relevant Options (in which event the Calculation Agent shall make appropriate adjustments to the Delivery Obligation), if Dealer determines, in good faith and in its commercially reasonable discretion, that such extension is reasonably necessary or appropriate to preserve Dealer’s commercially reasonable hedging or hedge unwind activity hereunder in light of existing liquidity conditions in the cash market, the stock borrow market or other relevant market or to enable Dealer to effect purchases of Shares or Share Termination Delivery Units in connection with its commercially reasonable hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer).

(b)    Additional Termination Event. The occurrence of an event of default with respect to Counterparty under the terms of the Convertible Securities as set forth in Section 6.01 of the Indenture shall constitute an Additional Termination Event with respect to which the Transaction is the sole Affected Transaction and Counterparty is 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.

(c)    Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If Dealer shall owe Counterparty any amount pursuant to Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Counterparty shall have the right, in its sole discretion, to require Dealer 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 (which written confirmation shall contain the representation and warranty set forth in Section 7), no later than 9:30 A.M., New York City time, on the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable (“Notice of Share Termination”); provided that if Counterparty does not elect to require Dealer to satisfy its Payment Obligation by the Share Termination Alternative, Dealer shall have the right, in its sole discretion, to elect to satisfy its Payment Obligation by the Share Termination Alternative, notwithstanding Counterparty’s failure to elect or election to the contrary; and provided further that Counterparty 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 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 Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party or an Extraordinary Event, which Event of Default, Termination Event or Extraordinary Event resulted from an event or events within Counterparty’s control. Upon such Notice of Share Termination, the following provisions shall apply on the Scheduled Trading Day immediately following the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable:

Share Termination Delivery

shall adjust the Share Termination Delivery Property by replacing any fractional portion of the aggregate amount of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.

(d)    Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the Shares (the “Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction in a commercially reasonable manner cannot be sold in the U.S. public market by Dealer without registration under the Securities Act, Counterparty shall, at its election: (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act to cover the resale of such Hedge Shares and (A) enter into an agreement, in form and substance satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered offering, (B) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (E) afford Dealer a reasonable opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities; provided that if Counterparty elects clause (i) above but the items referred to therein are not completed in a timely manner, or if Dealer, in its sole discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii) or clause (iii) of this Section 8(d) shall apply at the election of Counterparty; (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Dealer, including customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Dealer, due diligence rights (for Dealer or any designated buyer of the Hedge Shares from Dealer), and best efforts obligations to provide opinions and certificates and such other documentation as is customary for private placements agreements, all commercially reasonably acceptable to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary to compensate Dealer for any commercially reasonable discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or (iii) purchase the Hedge Shares from Dealer at the “Daily VWAP” (as defined in the Indenture) on such Exchange Business Days, and in the amounts, commercially reasonably requested by Dealer. This Section 8(d) shall survive the termination, expiration or early unwind of the Transaction.

(e)    Repurchase and Conversion Rate Adjustment Notices. Counterparty shall, at least two Exchange Business Days prior to any day on which Counterparty effects any repurchase of Shares or consummates or otherwise engages in any transaction or event (a “Conversion Rate Adjustment Event”) that could reasonably be expected to lead to an increase in the Conversion Rate, give Dealer a written notice of such repurchase or Conversion Rate Adjustment Event (a “Repurchase Notice”) on such day if, following such repurchase or Conversion Rate Adjustment Event, the Notice Percentage would reasonably be expected to be (i) greater than 14.5% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Notice Percentage as of the date hereof). The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of which is the Number of Shares plus the number of shares underlying any other convertible bond hedge transactions or call options sold by Dealer to Counterparty and the denominator of which is the number of Shares outstanding on such day. In the event that Counterparty fails to provide Dealer with a Repurchase Notice on the day and in the manner specified in this Section 8(e) then Counterparty agrees to indemnify and hold harmless Dealer, its affiliates and their respective directors, officers, employees, agents and controlling persons (Dealer and each such person being an “Indemnified Party”) from and against any and all losses (including losses relating to the 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 and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without limitation, Section 16 of the Exchange Act or under any state or federal law, regulation or regulatory order, relating to or arising out of such failure. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement and shall inure to the benefit of any permitted assignee of Dealer.

(f)    Transfer and Assignment. Either party may transfer or assign any of its rights or obligations under the Transaction with the prior written consent of the non-transferring party, such consent not to be unreasonably withheld or delayed; provided that Dealer may transfer or assign without any consent of Counterparty its rights and obligations hereunder, in whole or in part, to any person, or any person whose obligations would be guaranteed by a person, in either case, of credit quality equivalent to Dealer’s (or its ultimate parent’s). If at any time at which (1) the Equity Percentage exceeds 8% or (2) 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 Section 203 of the Delaware General Corporation Law or other federal, state or local law, rule, regulation or regulatory order or organizational documents or contracts of Counterparty applicable to ownership of Shares (“Applicable Restrictions”), 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, registration, filing or notification obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person under Applicable Restrictions 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 or other designated transactions), or have any other adverse effect on a Dealer Person, under Applicable Restrictions minus (y) 1% of the number of Shares outstanding on the date of determination (either such condition described in clause (1) or (2), an “Excess Ownership Position”), Dealer, in its discretion, is unable to effect a transfer or assignment to a third party after 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, 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 an Excess Ownership Position would no longer exist following the resulting partial termination of the Transaction (after taking into account commercially reasonable adjustments to Dealer’s commercially reasonable Hedge Positions from such partial termination). 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 or Section 8(c) 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) Counterparty were the sole Affected Party with respect to such partial termination, (iii) such portion of the Transaction were the only Terminated Transaction and (iv) Dealer were 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. The “Equity 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 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 (collectively, “Dealer Group”) “beneficially own” (within the meaning of Section 13 of the Exchange Act) without duplication on such day and (B) the denominator of which is the number of Shares outstanding on such day. In the case of a transfer or assignment by Counterparty of its rights and obligations hereunder and under the Agreement, in whole or in part (any such Options so transferred or assigned, the “Transfer Options”), to any party, withholding of such consent by Dealer shall not be considered unreasonable if such transfer or assignment does not meet the reasonable conditions that Dealer may impose including, but not limited, to the following conditions:

(A)    With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification obligations pursuant to Section 8(e) or any obligations under Section 2 (regarding Extraordinary Events) or 8(d) of this Confirmation;

(B)    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”));

(C)    Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third party (including, but not limited to, undertakings with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and execution of any

documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty as are requested by, and reasonably satisfactory to, Dealer;

(D)    Dealer shall not, as a result of such transfer and assignment, be required to pay the transferee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment;

(E)    An Event of Default, Potential Event of Default or Termination Event shall not occur as a result of such transfer and assignment;

(F)    Without limiting the generality of clause (B), Counterparty shall have caused the transferee to make such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

(G)    Counterparty shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment.

(g)    Delivery of Shares. Notwithstanding anything to the contrary herein, Dealer may, by prior notice to Counterparty, satisfy its obligation to deliver any Shares or other securities on any date due (an “Original Delivery Date”) by making separate deliveries of Shares or such securities, as the case may be, at more than one time on or prior to such Original Delivery Date, so long as the aggregate number of Shares and other securities so delivered on or prior to such Original Delivery Date is equal to the number required to be delivered on such Original Delivery Date.

(h)    Disclosure. Effective from the date of commencement of discussions concerning the Transaction, Counterparty 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 Counterparty relating to such tax treatment and tax structure.

(i)    No Netting and Set-off. The provisions of Section 2(c) of the Agreement shall not apply to the Transaction.

(j)    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 Counterparty’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than during Counterparty’s bankruptcy to any claim arising as a result of a breach by Counterparty of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that the obligations of Counterparty under this Confirmation are not secured by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement.

In the event the sale by Counterparty of the Base Convertible Securities is not consummated pursuant to the Purchase Agreement for any reason by the close of business in New York on December 10, 2014 (or such later date as agreed upon by the parties) (December 10, 2014 or such later date being the “Early Unwind Date”), the Transaction shall automatically terminate (the “Early Unwind”) on the Early Unwind Date and the Transaction and all of the respective rights and obligations of Dealer and Counterparty hereunder shall be cancelled and terminated and Counterparty shall pay to Dealer an amount in cash equal to the aggregate amount of costs and expenses relating to the unwinding of Dealer’s hedging activities in respect of the Transaction (including market losses incurred in reselling any Shares purchased by Dealer or its affiliates in connection with such hedging activities, unless Counterparty agrees to purchase any such Shares at the cost at which Dealer purchased such Shares) or, at the election of Counterparty, deliver to Dealer Shares with a value equal to such amount, as determined by the Calculation Agent, in which event the parties shall enter into customary and commercially reasonable documentation relating to the registered or exempt resale of such Shares. Following such termination, cancellation and payment, each party shall be released and discharged by the other party from, and agrees not to make any claim against the other party with respect to, any obligations or liabilities of either party arising out of, and to be performed in connection with, the Transaction either prior to or after the Early Unwind Date. Dealer and Counterparty represent and acknowledge to the other that upon an Early Unwind and following the payment referred to above, all obligations with respect to the Transaction shall be deemed fully and finally discharged.

(l)    Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether, when or in what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the “Daily VWAP” (as defined in the Indenture); (D) any market activities of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the “Daily VWAP” (as defined in the Indenture), each in a manner that may be adverse to Counterparty; and (E) the Transaction is a derivatives transaction in which it has granted Dealer an option, and Dealer may purchase shares for its own account at an average price that may be greater than, or less than, the price paid by Counterparty under the terms of the Transaction.

(m)    Method of Delivery. Whenever delivery of funds or other assets is required hereunder by or to Counterparty, such delivery shall be effected through DBSI. In addition, all notices, demands and communications of any kind relating to the Transaction between Dealer and Counterparty shall be transmitted exclusively through DBSI.

(n)    Wall Street Transparency and Accountability Act. In connection with Section 739 of the Wall Street Transparency and Accountability Act of 2010 (the “WSTAA”), the parties hereby agree that neither the enactment of the WSTAA (or any statute containing any legal certainty provision similar to Section 739 of the WSTAA) or any regulation under the WSTAA (or any such statute), nor any requirement under the WSTAA (or any statute containing any legal certainty provision similar to Section 739 of the WSTAA) or an amendment made by the WSTAA (or any such statute), shall limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs, regulatory change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging or Illegality).

871(m) of the Code (or any Treasury regulations or other guidance issued thereunder). For the avoidance of doubt, a FATCA Withholding Tax is a Tax the deduction or withholding of which is required by applicable law for the purposes of Section 2(d) of the Agreement.

EACH OF COUNTERPARTY AND DEALER HEREBY IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THE AGREEMENT, THIS CONFIRMATION AND THE TRANSACTION HEREUNDER.
