 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 the purposes of the Equity Definitions and to a “Swap Transaction”
for the purposes of the Swap Definitions. For purposes of the Transaction, “Warrant Style”, “Warrant Type”, “Number of Warrants” and “Warrant Entitlement” (each as defined below) shall be used herein as if
such terms were referred to as “Option Style”, “Option Type”, “Number of Options” and “Option Entitlement”, respectively, in the 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 Master 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:

promptly make available to Bank an effective registration

  

 3 









			
		  	statement (the “Registration Statement”) filed pursuant to Rule 415 under the Securities Act and such prospectuses as Bank may reasonably request to comply with the
applicable prospectus delivery requirements (the “Prospectus”) for the resale by Bank of such number of Shares as Bank shall reasonably specify in accordance with this paragraph, such Registration Statement to be effective
and Prospectus to be current until the earliest of the date on which (a) all Delivered Shares have been sold by Bank or returned to Counterparty pursuant to the Net Physical Settlement Adjustment provision above, (b) Bank has advised Counterparty
that it no longer requires that such Registration Statement be effective, (c) all remaining Delivered Shares could be sold by Bank without registration pursuant to Rule 144 promulgated under the Securities Act (the “Registration
Period”) or (d) Counterparty has provided a legal opinion in form and substance satisfactory to Bank (with customary assumptions and exceptions) that the Shares issuable upon exercise of these Warrants will be freely tradable under the
Securities Act upon delivery to Bank and not subject to any legend restricting transferability. It is understood that the Registration Statement and Prospectus may cover a number of Shares equal to the aggregate number of Shares (if any) reasonably
estimated by Bank to be potentially deliverable by Counterparty in connection with Net Physical Settlement hereunder (not to exceed the Maximum Deliverable Share Amount);
		
		  	Notwithstanding the foregoing, the Registration Statement and Prospectus provided for by this paragraph shall be subject to the same suspension of sales during “blackout dates” as
provided in the following paragraph (ii).
		
		  	(ii) In the event that Bank notifies Counterparty that Bank has reasonably determined after advice from counsel that there is a substantial material risk that the Shares are subject to
restrictions on transfer in the hands of Bank pursuant to the rules and regulations under the Securities Act, Counterparty will enter into a registration rights agreement with Bank in form and substance reasonably acceptable to Bank, which agreement
will contain among other things, customary representations and warranties and indemnification, restrictions on sales during “blackout dates” as provided for in the registration rights agreement (the “Registration Rights
Agreement”) entered into between Counterparty and the Initial Purchasers in connection with Counterparty’s 0.50% Convertible Senior Notes due 2011 (the “Convertible Notes”), and other rights relating to the
registration of a number of Shares equal to the number of Delivered Shares and others Shares deliverable hereunder up to the Maximum Deliverable Share Amount.
		
		  	(iii) Counterparty shall promptly pay to Bank a $0.04 per Share fee with all Shares delivered in connection with Net Physical Settlement pursuant to a Registration Statement.
		
		  	(iv) In the event Counterparty fails to comply with any of the conditions set forth in “Conditions to Net Physical Settlement” herein, Counterparty shall settle the
Transaction through Cash Settlement; provided however, that notwithstanding the foregoing, Counterparty may deliver unregistered Shares. In such case, the value of any unregistered Shares so delivered shall be discounted to reflect
their market value (calculated in a commercially reasonable manner) or the cost (calculated in a commercially reasonable manner) to Bank of trading Shares in order to close out its hedge position, if any, and such discounted value shall be used in
place of the Settlement Price for purposes of determining the number of Delivered Shares. In no event shall Counterparty be required to top-up the delivery in cash.

	Limitations on Net Physical Settlement by Counterparty:	  	Notwithstanding anything herein or in the Master Agreement to the contrary, the number of Shares that may be delivered at settlement by Counterparty shall not exceed 8,805,888 at any time
(“Maximum Deliverable Share Amount”).
		
		  	Counterparty represents and warrants that the number of Available Shares as of the Trade Date is greater than the Maximum Deliverable Share Amount. Counterparty covenants and agrees that
Counterparty shall not take any action of corporate governance or otherwise to reduce the number of Available Shares below the Maximum Deliverable Share Amount.
		
		  	For this purpose, “Available Shares” means the number of Shares Counterparty currently has authorized (but not issued and outstanding) less the maximum number of Shares
that may be required to be issued by Counterparty in connection with stock options, convertibles, and other commitments of Counterparty that may require the issuance or delivery of Shares in connection therewith.

		  	(b) Share-for-Other: Cancellation and Payment (Calculation Agent Determination)
		
		  	(c) Share-for-Combined: Cancellation and Payment (Calculation Agent Determination)
		
		  	With respect to any Extraordinary Events hereunder, upon the occurrence of Cancellation and Payment in whole or in part, the parties agree that the amount to be paid, in accordance with the
Equity Definitions, shall constitute a Transaction Early Termination Amount, subject to satisfaction by the payment or delivery of Shares or cash as set forth in the Early Termination section below.

	Additional Agreements:	  	If due to the occurrence of an Extraordinary Event or otherwise Counterparty would be obligated to pay cash to Bank pursuant to the terms of this Confirmation for any reason without having had
the right (other than pursuant to this paragraph) to elect to deliver Shares in satisfaction of such payment obligation, then Counterparty may elect to deliver to Bank a number of Shares (whether registered or unregistered) 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 sold by Bank over a reasonable
period of time to realize the cash equivalent of such payment obligation taking into account any applicable discount (determined in a commercially reasonable manner) to reflect any restrictions on transfer as well as the market value of the Shares).
Further, if Counterparty is delivering Shares as a result of a Merger Event, the Settlement Date will be immediately prior to the effective time of the Merger Event and the Shares will be deemed delivered at such time such that Bank will be a holder
of the Shares prior to such effective time. Settlement relating to any delivery of Shares pursuant to this paragraph shall occur within a reasonable period of time. The number of Shares delivered pursuant to this paragraph shall not exceed the
Maximum Deliverable Share Amount and shall be subject to the provisions under “Early Termination” hereof regarding Proceeds Amount.
		
	Early Termination:	  	Notwithstanding any provision to the contrary, upon the designation of an Early Termination Date hereunder, a party’s payment obligation in respect of the Transaction only as determined in
accordance with Second Method and Market Quotation (the “Transaction Early Termination Amount”) may, at the option of Counterparty, be satisfied by the party owing such amount by the delivery of a number of Shares equal to
the Transaction Early Termination Amount divided by the Termination Price (“Early Termination Stock Settlement”); provided,

  

 6 









			
		  	however, that Counterparty must notify Bank of its election of Early Termination Stock Settlement by the close of business on the day that is two Exchange Business Days following the
day that the notice designating the Early Termination Date is effective.
		
		  	“Termination Price” means the closing price per Share on the Exchange on the Early Termination Date.
		
		  	A number of Shares calculated as being due in respect of any Early Termination Stock Settlement will be deliverable on the third Exchange Business Day following the date that notice pursuant
to Section 6(d)(i) of the Master Agreement specifying the number of Shares deliverable is effective. Section 6(d)(i) of the Master Agreement is hereby amended by adding the following words after the word “paid” in the fifth
line thereof: “or any delivery is to be made, as applicable.”
		
		  	On or prior to the Early Termination Date (if Early Termination Stock Settlement is elected), if so requested by Bank, Counterparty shall enter into a registration rights agreement with Bank
in form and substance reasonably acceptable to Bank which agreement will contain among other things, customary representations and warranties and indemnification, restrictions on sales during “blackout dates” as provided for in the
Registration Rights Agreement and shall satisfy the conditions contained therein and Counterparty shall file and diligently pursue to effectiveness a Registration Statement pursuant to Rule 415 under the Securities Act. If and when such Registration
Statement shall have been declared effective by the Securities and Exchange Commission, Counterparty shall have made available to Bank such Prospectuses as Bank may reasonably request to comply with the applicable prospectus delivery requirements
for the resale by Bank of such number of Shares as Bank shall specify (or, if greater, the number of Shares that Counterparty shall specify). Such Registration Statement shall be effective and Prospectus shall be current until the earliest of the
date on which (i) all Shares delivered by Counterparty in connection with an Early Termination Date, (ii) Bank has advised Counterparty that it no longer requires that such Registration Statement be effective or (iii) all remaining Shares could be
sold by Bank without registration pursuant to Rule 144 promulgated under the Securities Act (the “Termination Registration Period”). It is understood that the Registration Statement and Prospectus will cover a number of
Shares equal to the number of Shares plus the aggregate number of Shares (if any) reasonably estimated by Bank to be potentially deliverable by Counterparty in connection with Early Termination Stock Settlement hereunder, but in no event exceeding
the Maximum Deliverable Share Amount. On each day during the Registration Period Counterparty shall represent that each of its filings under the Securities Act, the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), or other applicable securities laws that are required to be filed have been filed and that, as of the respective dates thereof and as of the date of this representation, there is no misstatement of a material fact contained
therein or omission of a material fact required to be stated therein or necessary to make the statements therein not misleading.
		
		  	If Counterparty does not deliver Shares subject to an effective Registration Statement as set forth above, Counterparty may deliver unregistered Shares in an amount determined by Bank based
upon Bank’s commercially reasonable judgment of the market value of such Shares. In no event shall Counterparty be required to deliver to Bank a number of Shares greater than the Maximum Deliverable Share Amount.

  

 7 









			
		  	If Bank receives Shares in connection with an Early Termination Stock Settlement that cannot be freely sold under the Securities Act or that are subject to any legend restricting
transferability, Bank shall sell such Shares in a commercially reasonable manner until the amount received by Bank for the sale of such Shares (net of transaction costs, calculated in a commercially reasonable manner) (the “Proceeds
Amount”) is equal to the Transaction Early Termination Amount. Any remaining Shares shall be returned to Counterparty. If the Proceeds Amount is less than the Transaction Early Termination Amount, Counterparty shall promptly deliver
additional Shares to Bank upon request until the dollar amount from the sale of such additional Shares by Bank (net of transaction costs, calculated in a commercially reasonable manner) equals the difference between the Transaction Early Termination
Amount and the Proceeds Amount. In no event shall Counterparty be required to deliver to Bank a number of Shares greater than the Maximum Deliverable Share Amount.
		
	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
applicable provisions of the Securities Act, the Exchange Act, and the rules and regulations thereunder, including, without limitation, Rule 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 Bank’s gross negligence or willful misconduct.
		
		  	Each party further represents that if such party (“X”) purchases any Shares from the other party pursuant to the Transaction, such purchase(s) will comply in all
material respects with (i) all laws and regulations applicable to X, and (ii) all contractual obligations of X.
		
		  	Each party acknowledges that the offer and sale of the Transaction to it is intended to be exempt from registration under the Securities Act by virtue of Section 4(2) thereof.
Accordingly, Counterparty represents and warrants to Bank 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, (ii) it is an “accredited
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. On or prior to the Trade
Date, Counterparty shall deliver to Bank a resolution of Counterparty’s board of directors authorizing the Transaction and such other certificate or certificates as Bank shall reasonably request.
		
		  	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, Bank 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.

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

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

  

	 	(1)	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 Convertible Notes; and 

  

	 	(2)	it has publicly disclosed all material information necessary for it 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). 

  

	 	(b)	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.


  

	 	(c)	No collateral shall be required by either party for any reason in connection with the Transaction. 

  

	 	(d)	Bank shall not be entitled to exercise any Warrant hereunder as provided below, and Automatic Exercise shall not apply with respect to any Warrant, to the extent the exercise of
such Warrant would cause Bank to become, directly or indirectly, the beneficial owner of more than 8.0 percent of the class of Counterparty’s equity securities that is comprised of the Shares for purposes of Section 13 of the
Exchange Act (in such case, an “Excess Share Owner”). 

 Bank shall provide prior notice to Counterparty
if the exercise of any Warrant hereunder would cause Bank to become directly or indirectly, an Excess Share Owner; provided that the failure of Bank to provide such notice shall not alter the effectiveness of the provisions set forth in the
preceding sentence and any purported exercise in violation of such provisions shall be void and have no effect. 
 If Bank is not entitled to
exercise any Warrant because such exercise would cause Bank to become, directly or indirectly, an Excess Share Owner and Bank thereafter disposes of Shares owned by it or any action is taken that would then permit Bank to exercise such Warrant
without such exercise causing it to become, directly or indirectly, an Excess Share Owner, then Bank shall provide notice of the taking of such action to Counterparty and such Warrant shall then become exercisable by Bank to the extent such Warrant
is otherwise or had otherwise become exercisable hereunder. In such event, the Expiration Date with respect to such Warrant shall be the date on which Counterparty receives such notice from Bank, and the related Settlement Date shall be as soon as
reasonably practicable after receipt of such notice but no more than three (3) Exchange Business Days thereafter (but in no event shall the Settlement Date occur prior to the date on which it would have otherwise occurred but for the provisions
of this paragraph (d)); provided that the related Net Physical Settlement Amount shall be the same as the Net Physical Settlement Amount but for the provisions of this paragraph (d). In addition, within 30 calendar days of the Settlement
Date, Counterparty shall use its reasonable efforts to refrain from activities that could reasonably be expected to result in Bank’s ownership of Shares exceeding 10% of all issued and outstanding Shares.

thereunder are subject to individual negotiation by the parties and have not been executed or traded on a “trading facility” as defined in Section 1a(33) of the CEA, and it has entered into this Confirmation and the Transaction
in connection with its business or a line of business (including financial intermediation), or the financing of its business.

 No Violation or Conflict. Such execution, delivery and performance do not materially violate or conflict with any law known by it to be applicable to it, any provision of its constitutional documents, any order

 Acknowledgements: 
 (1) The parties acknowledge and agree that there are no other representations, agreements or other undertakings of the parties in relation to the Transaction, except as set forth in this Confirmation. 
 (2) The parties hereto intend for: 
  

	 	(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. 

 (3) The parties acknowledge and agree that in the event of an Early Termination Date as a result of an Event of
Default, the amount payable under the Master Agreement will be a cash amount calculated as described therein and that any delivery specified in the Transaction will no longer be required. 
 Amendment of Section 6(d)(ii). Section 6(d)(ii) of the Master Agreement is modified by deleting the words “on the
day” in the second line thereof and substituting therefor “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 therefor “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 the 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 Bank 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 Bank) 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 
  

 14 








 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.
