8. Other Provisions:

(a) Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer in accordance with the advice of outside counsel, the Shares (the “Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction 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, however, that if Dealer, in its sole reasonable 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(a) shall apply at the election of Counterparty; (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, to 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), opinions and certificates and such other documentation as is customary for private placements agreements, all reasonably acceptable to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for any 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 VWAP Price on such Exchange Business Days, and in the amounts, requested by Dealer. For the avoidance of doubt, under no circumstances shall Counterparty be obligated to make the election described in clause (iii) of the preceding sentence.

(b) 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 Notice Percentage as determined on such day is (i) greater than 2.0% 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,

11

the numerator of which is the Number of Shares 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(b) 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, 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, 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 shall inure to the benefit of any permitted assignee of Dealer.

(c) Additional Termination Events. (i) The occurrence of (A) an event of default with respect to Counterparty under the terms of the Convertible Debentures as set forth in Section 5.01 of the Fourth Supplemental Indenture or (B) an Amendment Event shall be 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.

“Amendment Event” means that Counterparty amends, modifies, supplements or obtains a waiver in respect of any term of the Indenture or the Convertible Debentures governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of Counterparty, any term relating to conversion of the Convertible Debentures (including changes to the conversion price, conversion settlement dates or conversion conditions), or any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Debentures to amend, in each case without the prior consent of Dealer.

(ii) If at any time the senior unsecured debt of Dealer is rated Baa1 or lower by Moody’s Investor Services, Inc. (“Moody’s”) or BBB+ or lower by Standard and Poor’s Rating Services (“S&P”) (a “Ratings Downgrade”), then an Additional Termination Event, with Counterparty as the sole Affected Party, the Transaction as the sole Affected Transaction and Counterparty as the party entitled to designate an Early Termination Date, shall occur on the date three Exchange Business Days following the occurrence of such Ratings Downgrade (the “Downgrade Deadline”) unless, on or prior to the Downgrade Deadline, either (i) Dealer has agreed to provide collateral to Counterparty on a mark-to-market basis to secure Dealer’s obligations hereunder on terms commercially reasonably acceptable to Counterparty and Dealer or (ii) Dealer shall have transferred and assigned its obligations hereunder to a person with (or whose obligations hereunder are fully and unconditionally guaranteed by a person with) a credit rating of A2 or higher from Moody’s and A or higher from S&P (and Counterparty agrees that it will not object to any such transfer and assignment). In the case of clause (i), eligible collateral shall include cash, cash equivalents and equity securities of Counterparty, including without limitation Shares and any warrants issued by Counterparty, and any other collateral reasonably acceptable to Counterparty, and the Calculation Agent shall make all determinations of exposure and collateral value.

(d) Right to Extend. Dealer may postpone any Settlement Date or any other date of valuation or delivery by Dealer to a date no later than the Final Disruption Date to an Exercise Date occurring on the Expiration Date, in the case of a date of valuation, or the date one Settlement Cycle following the Final Disruption Date applicable to an Exercise Date occurring on the Expiration Date, in the case of a date of delivery, 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 its reasonable discretion, that such extension is reasonably necessary or appropriate to preserve Dealer’s hedging or hedge

12

unwind activity hereunder in light of existing liquidity conditions in the cash market or the stock borrow market or other relevant market or 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 Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.

(e) Transfer and Assignment. Either party may transfer 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; 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 with (or whose obligations hereunder are fully and unconditionally guaranteed by a person with) a credit rating of “A” or higher from Standard and Poor’s Rating Services or “A2” or higher from Moody’s Investor Services, Inc.; provided further that at any time at which (1) the Equity Percentage exceeds 8%, (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 (the “DGCL Takeover Statute”) or any state or federal bank holding company or banking laws, or other federal, state or local regulations or regulatory orders 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 state or federal regulator) of a Dealer Person under Applicable Laws (including, without limitation, “interested stockholder” or “acquiring person” status under the DGCL Takeover Statute) and with respect to which such requirements have not been met or the relevant approval has not been received minus (y) 2% of the number of Shares outstanding on the date of determination (either such condition described in clause (1) or (2), an “Excess Ownership Position”), or (3) a Hedging Disruption has occurred and is continuing, if Dealer, in its discretion, is unable to effect a transfer or assignment to a third party in accordance with the requirements set forth above after using its commercially reasonable efforts on pricing terms reasonably acceptable to Dealer such that an Excess Ownership Position 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 Excess Ownership Position 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 shall be made pursuant to Section 6 of the Agreement 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 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. 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.

(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 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 this Confirmation is not secured by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement.

(g) Netting and Set-off.

(i) If on any date cash would otherwise be payable or Shares or other property would otherwise be deliverable hereunder or pursuant to the Agreement or pursuant to any other agreement between the parties by Counterparty to Dealer and cash would otherwise be payable or Shares or other property would otherwise be deliverable hereunder or pursuant to the Agreement

13

or pursuant to any other agreement between the parties by Dealer to Counterparty and the type of property required to be paid or delivered by each such party on such date is the same, then, on such date, each such party’s obligation to make such payment or delivery will be automatically satisfied and discharged and, if the aggregate amount that would otherwise have been payable or deliverable by one such party exceeds the aggregate amount that would otherwise have been payable or deliverable by the other such party, replaced by an obligation of the party by whom the larger aggregate amount would have been payable or deliverable to pay or deliver to the other party the excess of the larger aggregate amount over the smaller aggregate amount.

(ii) In addition to and without limiting any rights of set-off that a party hereto may have as a matter of law, pursuant to contract or otherwise, upon the occurrence of an Early Termination Date, Dealer shall have the right to terminate, liquidate and otherwise close out the Transaction and to set off any obligation or right that Dealer or any affiliate of Dealer may have to or against Counterparty hereunder or under the Agreement against any right or obligation Dealer or any of its affiliates may have against or to Counterparty, including without limitation any right to receive a payment or delivery pursuant to any provision of the Agreement or hereunder. In the case of a set-off of any obligation to release, deliver or pay assets against any right to receive assets of the same type, such obligation and right shall be set off in kind. In the case of a set-off of any obligation to release, deliver or pay assets against any right to receive assets of any other type, the value of each of such obligation and such right shall be determined by the Calculation Agent and the result of such set-off shall be that the net obligor shall pay or deliver to the other party an amount of cash or assets, at the net obligor’s option, with a value (determined, in the case of a delivery of assets, by the Calculation Agent) equal to that of the net obligation. In determining the value of any obligation to release or deliver Shares or any right to receive Shares, the value at any time of such obligation or right shall be determined by reference to the market value of the Shares at such time, as determined by the Calculation Agent. If an obligation or right is unascertained at the time of any such set-off, the Calculation Agent may in good faith estimate the amount or value of such obligation or right, in which case set-off will be effected in respect of that estimate, and the relevant party shall account to the other party at the time such obligation or right is ascertained.

(iii) Notwithstanding any provision of the Agreement (including without limitation Section 6(f) thereof) and this Confirmation (including without limitation this Section 8(g)) or any other agreement between the parties to the contrary, (A) Counterparty shall not net or set off its obligations under the Transaction, if any, against its rights against Dealer under any other transaction or instrument and (B) in the event of bankruptcy or liquidation of Counterparty, neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against any obligation such other party may have to it under the Agreement, this Confirmation or any other agreement between the parties hereto, by operation of law or otherwise. Dealer will give notice to Counterparty of any netting or set off effected under this provision.

(h) 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.

(i) 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.

(j) 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.

14

(k) Waiver of Trial by Jury. 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 TRANSACTION OR THE ACTIONS OF COUNTERPARTY OF ITS AFFILIATES OR DEALER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT HEREOF.

(l) Submission to Jurisdiction. Each party hereby irrevocably and unconditionally submits for itself and its property in any legal action or proceeding by the other party against it relating to the Transaction to which it is a party, or for recognition and enforcement of any judgment in respect thereof, 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.

(m) Governing Law. THIS CONFIRMATION SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT REFERENCE TO ITS CHOICE OF LAW DOCTRINE).
