	Attention:	  	Corporate Secretary

 Dear Sir / Madam: 
 The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the above-referenced
transaction entered into between Counterparty and Bank on the Trade Date specified below (the “Transaction”). This Confirmation constitutes a “Confirmation” as referred to in the Master Agreement specified below.

 The definitions and provisions contained in the 2000 ISDA Definitions (the “Swap Definitions”) and the 2002 ISDA
Equity Derivatives Definitions (the “Equity Definitions” and, together with the Swap Definitions, the “Definitions”), in each case as published by the International Swaps and Derivatives Association,
Inc., are incorporated into this Confirmation. In the event of any inconsistency between the Swap Definitions and the Equity Definitions, the Equity Definitions will govern, and in the event of any inconsistency between the Definitions and this
Confirmation, this Confirmation will govern. References herein to a “Transaction” shall be deemed to be references to a “Share Option Transaction” for purposes of the Equity Definitions and a “Swap Transaction” for the
purposes of the Swap Definitions. 
 This Confirmation evidences a complete binding agreement between you and us as to the terms of the
Transaction to which this Confirmation relates. This Confirmation (notwithstanding anything to the contrary herein), shall be subject to an agreement in the 1992 form of the ISDA Master Agreement (Multicurrency Cross Border) (the “Master
Agreement”) as if we had executed an agreement in such form (but without any Schedule and with the elections specified in the “ISDA Master Agreement” Section of this Confirmation) on the Trade Date of the Transaction. In the
event of any inconsistency between the provisions of that agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction. The parties hereby agree that the Transaction evidenced by this Confirmation shall be the
only Transaction subject to and governed by the Master Agreement. 
 The terms of the particular Transaction to which this Confirmation
relates are as follows:

	Conversion Event:	  	Each conversion of any Reference Note pursuant to the terms of the Note Indenture (the principal amount of Reference Notes so converted, the “Conversion Amount” with
respect to such Conversion Event) occurring before the Termination Date. For the avoidance of doubt, an exchange of a Reference Note in lieu of conversion pursuant to the Note Indenture will not be a “conversion”
thereunder.
		
		  	If the Conversion Amount for any Conversion Event is less than the aggregate principal amount of Reference Notes then outstanding, then the terms of the Transaction shall continue to apply,
subject to the terms and conditions set forth herein, with respect to the remaining outstanding principal amount of the Reference Notes.

same may be amended, modified or supplemented, subject to the “Additional Termination Events” provisions of this Confirmation.
		
	Termination Date:	  	The earlier of (i) the Settlement Date relating to the final Valuation Date and (ii) the first day on which none of the Reference Notes remain outstanding, whether by virtue of conversion,

	Settlement Notice:	  	Counterparty shall provide Seller with one or more notices (which notices can be provided by the Trustee (as defined in the Note Indenture)) of its Settlement Method prior to the first

		  	Share Settlement (without regard to subsection (b) of the definition of Net Share Settlement). The Settlement Notices, collectively, will include (i) the number of Reference Notes being
converted, (ii) the first “trading day” in the relevant “conversion reference period” for the Reference Notes and (iii) the applicable Cash Percentage, if any.
		
	Settlement Date:	  	The third (3rd) “trading day” (as defined in the Note Indenture) following the Valuation Date.

Event if neither a Settlement Notice nor a Conversion Notice shall be delivered to the Seller prior to the start of the “conversion reference period” (as defined in the Note Indenture) applicable to such Conversion Event, the Net Share
Settlement Amount for such Conversion Event shall be reduced by an amount determined by the parties, in a commercially reasonable manner each acting in good faith, to account for the reduced number of “trading days” during the period from
the delivery of such notice to the end of the applicable “conversion reference period” rather than over the entire “conversion reference period” (as defined in the Note Indenture). No reduction of the Net Share Settlement Amount
shall reduce the Net Share Settlement Amount below zero.
		
	Net Cash Settlement Amount:	  	For each Conversion Event, an amount equal to the cash delivered by Counterparty in excess of the principal amount of the applicable Reference Notes for such Conversion Event under the Note
Indenture, provided that with respect to such Conversion Event if the Settlement Notice shall not be delivered to the Seller prior to the start of the “conversion reference period” (as defined in the Note Indenture) applicable to such
Conversion Event, the Net Cash Settlement Amount for such Conversion Event shall be reduced by an amount determined by the parties, in a commercially reasonable manner each acting in good faith, to account for the reduced number of “trading
days” during the period from the delivery of such notice to the end of the applicable “conversion reference period” rather than over the entire “conversion reference period” (as defined in the Note Indenture). No reduction
of the Net Cash Settlement Amount shall reduce the Net Cash Settlement Amount below zero.

 Additional Agreements, Representations and Covenants of Counterparty, Etc.: 
  

	 	1.	Counterparty hereby represents and warrants to Seller, on each day from the Trade Date to and including the earlier of (i) April 25, 2006 and (ii) the date by which
Seller is able to initially complete a hedge of its position relating to the Transaction, that: 

  

	 	a.	it will not, and will not permit any person or entity subject to its control to, bid for or purchase Shares during such period except as disclosed in the Offering Memorandum
relating to the Reference Notes; and 

  

	 	b.	Counterparty has publicly disclosed all material information necessary for Counterparty to be able to purchase or sell Shares in compliance with applicable federal securities laws
and that it has publicly disclosed all material information with respect to its condition (financial or otherwise). 

  

	 	2.	The parties hereby agree that all documentation with respect to the Transaction is intended to qualify the Transaction as an equity instrument for purposes of EITF 00-19. If
Counterparty would be obligated to receive cash from Seller pursuant to the terms of this Confirmation for any reason without having had the right (other than pursuant to this paragraph (2)) to elect to receive Shares in satisfaction of such
payment obligation, then Counterparty may elect that Seller deliver to Counterparty a number of Shares having a cash value equal to the amount of such payment obligation (such number of Shares to be delivered to be determined by the Calculation
Agent acting in a commercially reasonable manner to determine the number of Shares that could be purchased over a reasonable period of time with the cash equivalent of such payment obligation). Settlement relating to any delivery of Shares pursuant
to this paragraph (2) shall occur within a reasonable period of time. 

 Additional Termination Events: 
 The occurrence of any of the following shall be an Additional Termination Event for purposes of the Transaction: 
  

	 	1.	Amendment Event. If an Amendment Event (as defined below) occurs, the Transaction shall terminate in its entirety and, notwithstanding anything to the contrary herein, no
payments shall be required hereunder in connection with the Additional Termination Event arising as a result of such Amendment Event. 

 “Amendment Event” means that Counterparty amends, modifies, supplements or obtains a waiver of any term of the Note Indenture or the Reference Notes relating to the principal amount, coupon, maturity, repurchase
obligation of Counterparty, redemption right of Counterparty, any material term relating to conversion of the Reference Notes (including changes to the conversion price, conversion settlement dates or conversion conditions), or any other term that
would require consent of the holders of 100% of the principal amount of the Reference Notes to amend. 
  

	 	2.	Repayment Event. If a Repayment Event (as defined below) occurs, the Transaction shall terminate only to the extent of the principal amount of Reference Notes that cease to
be outstanding as a result of such Repayment Event and, notwithstanding anything to the contrary herein, no payments shall be required hereunder in connection with the Additional Termination Event arising as a result of such Repayment Event.


 “Repayment Event” means that (a) any Reference Notes are repurchased (whether in connection
with or as a result of a change of control, howsoever defined, or for any other reason) by Counterparty, (b) any Reference Notes are delivered to Counterparty in exchange for delivery of any property or assets of Counterparty or any of its
subsidiaries (howsoever described), other than as a result of and in connection with a Conversion Event, (c) any principal of any of the Reference Notes is repaid prior to the Final Maturity Date (as defined in the Note Indenture) (whether
following acceleration of the Reference Notes or otherwise), provided that no payments of cash made in respect of the conversion of a Reference Note shall be deemed a payment of principal 
  

 5 








 under this clause (c), (d) any Reference Notes are exchanged by or for the benefit of the holders
thereof for any other securities of Counterparty (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction or (e) any of the Reference Notes is surrendered by Counterparty to the trustee for
cancellation, other than registration of a transfer of such Reference Notes or as a result of and in connection with a Conversion Event. 
  

	 	3.	Initial Purchase Event. If an Initial Purchase Event (as defined below) occurs, the Transaction shall terminate automatically in its entirety and, notwithstanding anything to
the contrary herein, only the payments specified below shall be required hereunder in connection with the Additional Termination Event arising as a result of such Initial Purchase Event. 

 “Initial Purchase Event” means that the transactions contemplated by the purchase agreement among Counterparty and Merrill Lynch,
Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. Incorporated and Banc of America Securities LLC, as representatives of the several initial purchasers named in Schedule A thereto, dated as of April 19, 2006 (the
“Purchase Agreement”), relating to the purchase of the Reference Notes, shall fail to close for any reason. 
 If an
Initial Purchase Event occurs for any reason other than a breach of the Purchase Agreement by Banc of America Securities LLC or an affiliate thereof that acts as Initial Purchaser, then all payments previously made hereunder shall be returned to the
person making such payment, including the Initial Payment Amount, less an amount equal to the product of (a) 8,386,560 Shares and (b) the sum of (i) US$0.50 per Share and (ii) an amount equal to the excess, if any, of the closing
price of the Shares on the Trade Date over the closing price of the Shares on the date of the Termination Event (the “Break Expense”); provided that any negative amount shall be replaced by zero and provided further that to
the extent the Initial Payment Amount has not been paid, Counterparty shall promptly pay Seller the Break Expense. Seller and Counterparty agree that actual damages would be difficult to ascertain under these circumstances and that the amount of
liquidated damages resulting from the determination in the preceding sentence is a good faith estimate of such damages and not a penalty. 
 If an Initial Purchase Event occurs due to a breach of the Purchase Agreement by Banc of America Securities LLC or an affiliate thereof that acts as Initial Purchaser, then all payments previously made hereunder, including the Initial
Payment Amount, shall be promptly returned to the person making such payment. 
 Staggered Settlement: 
 If Seller determines reasonably and in good faith that the number of Shares required to be delivered to Counterparty hereunder on any Settlement Date would exceed 8.0% of
all outstanding Shares, then Seller may, by notice to Counterparty on or prior to such Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares comprising the related Net Share Settlement Amount on two or
more dates (each, a “Staggered Settlement Date”) as follows: 
  

	 	1.	in such notice, Seller will specify to Counterparty the related Staggered Settlement Dates (the first of which will be such Nominal Settlement Date and the last of which will be no
later than twenty (20) “trading days” (as defined in the Note Indenture) following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date; 

  

	 	2.	the aggregate number of Shares that Seller will deliver to Counterparty hereunder on all such Staggered Settlement Dates will equal the number of Shares that Seller would otherwise
be required to deliver on such Nominal Settlement Date; and 

  

	 	3.	the Net Share Settlement terms will apply on each Staggered Settlement Date, except that the Shares comprising the Net Share Settlement Amount will be allocated among such Staggered
Settlement Dates as specified by Seller in the notice referred to in clause (1) above. 

  

 6 








 Notwithstanding anything herein to the contrary, solely in connection with a Staggered Settlement Date, Seller shall be
entitled to deliver Shares to Counterparty from time to time prior to the date on which Seller would be obligated to deliver them to Counterparty pursuant to Net Share Settlement terms set forth above, and Counterparty agrees to credit all such
early deliveries against Seller’s obligations hereunder in the direct order in which such obligations arise. No such early delivery of Shares will accelerate or otherwise affect any of Counterparty’s obligations to Seller hereunder.

  

			
		
	Compliance with Securities Laws:	  	Each party represents and agrees that it has complied, and will comply, in connection with the Transaction and all related or contemporaneous sales and purchases of Shares, with the

thereunder, including, without limitation, Rules 10b-5 and 13e and Regulation M under the Exchange Act; provided that each party shall be entitled to rely conclusively on any information communicated by the other party concerning such other
party’s market activities; and provided further that Counterparty shall have no liability as a result of a breach of this representation due to Seller’s gross negligence or willful misconduct.

investor” as that term is defined in Regulation D as promulgated under the Securities Act and (iii) the disposition of the Transaction is restricted under this Confirmation, the Securities Act and state securities laws.
		
		  	Counterparty represents and acknowledges that as of the date hereof:
		
		  	(a) No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court is required in connection with the execution, delivery or performance by
Company of this Confirmation, except such as have been obtained or made and such as may be required under the Securities Act or state securities laws.
		
		  	(b) without limiting the generality of Section 13.1 of the Equity Definitions, Seller is not making any representations or warranties with respect to the treatment of the Transaction
under FASB Statements 149 or 150, EITF Issue No. 00-19 (or any successor issue statements) or under FASB’s Liabilities & Equity Project.

	 	(a)	the Transaction to be a “securities contract” as defined in Section 741(7) of Title 11 of the United States Code (the “Bankruptcy
Code”), qualifying for the protections under Section 555 of the Bankruptcy Code; 

  

	 	(b)	a party’s right to liquidate the Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Master Agreement with respect to the other
party to constitute a “contractual right” as defined in the Bankruptcy Code; 

  

	 	(c)	all payments for, under or in connection with the Transaction, all payments for the Shares and the transfer of such Shares to constitute “settlement payments” as defined
in the Bankruptcy Code. 

 Amendment of Section 6(d)(ii). Section 6(d)(ii) of the Master Agreement is modified
by deleting the words “on any day” in the second line thereof and substituting therefore “on the day that is three Local Business Days after the day.” Section 6(d)(ii) is further modified by deleting the words
“two Local Business Days” in the fourth line thereof and substituting therefore “three Local Business Days.” 
 Amendment of
Definition of Reference Market-Makers. The definition of “Reference Market-Makers” in Section 14 is hereby amended by adding in clause (a) after the word “credit” and before the word “and” the words
“or to enter into transactions similar in nature to Transactions.” 
 Consent to Recording. Each party consents to the recording of the
telephone conversations of trading and marketing personnel of the parties and their Affiliates in connection with this Confirmation. To the extent that one party records telephone conversations (the “Recording Party”) and the
other party does not (the “Non-Recording Party”), the Recording Party shall in the event of any dispute, make a complete and unedited copy of such party’s tape of the entire day’s conversations with the
Non-Recording Party’s personnel available to the Non-Recording Party. The Recording Party’s tapes may be used by either party in any forum in which a dispute is sought to be resolved and the Recording Party will retain tapes for a
consistent period of time in accordance with the Recording Party’s policy unless one party notifies the other that a particular transaction is under review and warrants further retention. 
 Disclosure. Each party hereby acknowledges and agrees that Seller has authorized Counterparty to disclose the Transaction and any related hedging transaction
between the parties if and to the extent that Counterparty reasonably determines (after consultation with Seller) that such disclosure is required by law or by the rules of NASDAQ or any securities exchange. Notwithstanding any provision in this
Confirmation or the Master Agreement, in connection with Section 1.6011-4 of the Treasury Regulations, the parties hereby agree that each party (and each employee, representative, or other agent of such party) may disclose to any and all
persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such U.S. tax treatment
and U.S. tax structure, other than any information for which nondisclosure is reasonably necessary in order to comply with applicable securities laws. 
 Severability. If any term, provision, covenant or condition of this Confirmation, or the application thereof to any party or circumstance, shall be held to be invalid or unenforceable in whole or in part for any reason, the remaining
terms, provisions, covenants, and conditions hereof shall continue in full force and effect as if this Confirmation had been executed with the invalid or unenforceable provision eliminated, so long as this Confirmation as so modified continues to
express, without material change, the original intentions of the parties as to the subject matter of this Confirmation and the deletion of such portion of this Confirmation will not substantially impair the respective benefits or expectations of
parties to this Confirmation; provided, however, that this severability provision shall not be applicable if any provision of Section 2, 5, 6 or 13 of the Master Agreement (or any definition or
provision in Section 14 to the extent that it relates to, or is used in or in connection with any such Section) shall be so held to be invalid or unenforceable.
