Re: Call Option Transaction





     The purpose of this letter agreement (this "Confirmation") is to confirm the terms and conditions of the call option transaction entered into between JPMorgan Chase Bank,
National Association, London Branch ("JPMorgan") andSonoSite, Inc. ("Counterparty") on the Trade Date specified below (the "Transaction").  This letter agreement constitutes a "Confirmation" as referred to in the ISDA Master Agreement
specified below.  This Confirmation shall replace any previous agreements and serve as the final documentation for this Transaction.





     The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the "Equity Definitions"), as published by the International Swaps and Derivatives
Association, Inc. ("ISDA") are incorporated into this Confirmation.  In the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern.  Certain defined terms used herein have the meanings assigned
to them in the Prospectus Supplement dated July 10, 2007 to the Prospectus dated May 29, 2007 (as so supplemented, the "Prospectus") relating to the USD 200,000,000 principal amount of Convertible Senior Notes due 2014, (the "Convertible Notes" and each
USD 1,000 principal amount of Convertible Notes, a "Convertible Note") issued by Counterparty pursuant to an Indenture to be dated July 16, 2007 (the "Base Indenture") and a first supplemental indenture dated as of July 16, 2007 (the "First
Supplemental Indenture", together with the Base Indenture, the "Indenture") between Counterparty and Wells Fargo Bank, National Association, as trustee.  In the event of any inconsistency between the terms defined in the Prospectus, the Indenture and
this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined herein by reference to the Indenture and
(ii) sections of the Indenture that are referred to herein will conform to the descriptions thereof in the Prospectus.  If any such definitions in the Indenture or any such sections of the Indenture differ from the descriptions thereof in the Prospectus, the
descriptions thereof in the Prospectus will govern for purposes of this Confirmation.  The parties further acknowledge that the First Supplemental Indenture section numbers used herein are based on the draft of the First Supplemental Indenture dated July 9,
2007, and if any such section numbers are changed in the First Supplemental Indenture as executed, the parties will amend this Confirmation in good faith to preserve the intent of the parties.  For the avoidance of doubt, references to the Indenture herein are
references to the Indenture as in effect on the date of its execution and if the Indenture is amended following its execution, any such amendment will be disregarded for purposes of this Confirmation unless the parties agree otherwise in writing.





     Each party is hereby advised, and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial transactions and has taken
other material actions in reliance upon the parties' entry into the Transaction to which this Confirmation relates on the terms and conditions set forth below.

election of the laws of the State of New York as the governing law) on the Trade Date.  In the event of any inconsistency between provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of the Transaction to which this
Confirmation relates.  The parties hereby agree that no Transaction other than the Transaction to which this Confirmation relates shall be governed by the Agreement.

8.     Representations and Warranties





     (a)     The representations and warranties of Counterparty set forth in Section 3 of the Underwriting Agreement (the "Underwriting Agreement") dated
as of July 10, 2007 between Counterparty and J.P. Morgan Securities Inc. as representative of the Underwriters are true and correct and are hereby deemed to be repeated to JPMorgan as if set forth herein.  Counterparty hereby further represents and warrants to
JPMorgan that:





              (i)     Counterparty is not and will not be required to register as an "investment company" as such
term is defined in the Investment Company Act of 1940, as amended.





              (ii)     It is an "eligible contract participant" (as such term is defined in Section 1a(12) of the
Commodity Exchange Act, as amended (the "CEA")) because one or more of the following is true:





Counterparty is a corporation, partnership, proprietorship, organization, trust or other entity and:





                          (A)      Counterparty has total assets in excess of USD
10,000,000;





                          (B)     the obligations of
Counterparty hereunder are guaranteed, or otherwise supported by a letter of credit or keepwell, support or other agreement, by an entity of the type described in Section 1a(12)(A)(i) through (iv), 1a(12)(A)(v)(I), 1a(12)(A)(vii) or 1a(12)(C) of the CEA;
or





                          (C)      Counterparty has a net
worth in excess of USD 1,000,000 and has entered into this Agreement in connection with the conduct of Counterparty's business or to manage the risk associated with an asset or liability owned or incurred or reasonably likely to be owned or incurred by Counterparty
in the conduct of Counterparty's business.





              (iii)     Each of it and its affiliates is not, on the date hereof, in possession of any material
non-public information with respect to Counterparty.





     (b)     JPMorgan represents and warrants to Counterparty that it is an "eligible contract participant" (as such term is defined in Section 1a(12) of the
CEA).





9.      Other Provisions:





     (a)     Opinion/Evidence of Authority.  Counterparty shall deliver to JPMorgan an opinion of counsel, dated as of the Trade Date, with
respect to the matters set forth in Section 3(a) of the Agreement.  JPMorgan shall deliver to Counterparty its evidence of authority on or prior to the Trade Date.





     (b)     Repurchase Notices.  Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give JPMorgan
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 16,393,000 (in the case of the first such notice) or (ii) thereafter more than
40,000 less than the number of Shares included in the immediately preceding Repurchase Notice.  Counterparty agrees to indemnify and hold harmless JPMorgan 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 JPMorgan'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 JPMorgan 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 JPMorgan 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 (c) 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.





     (c)     Regulation M.  Counterparty is not on the date hereof engaged in a distribution, as such term is used in Regulation M under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), of any securities of Counterparty, other than (i) a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7) of Regulation M and (ii) the distribution
of the Convertible Notes.  Counterparty shall not, until the second Scheduled Trading Day immediately following the Trade Date, engage in any such distribution.





     (d)     No Manipulation.  Counterparty is not entering into this Transaction to create actual or apparent trading activity in the Shares
(or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise in violation of the Exchange Act.





     (e)     Early Unwind.  In the event the sale of Convertible Notes is not consummated with the Underwriters for any reason by the close of
business in New York on July 16, 2007 (or such later date as agreed upon by the parties) (July 16, 2007 or such later date as agreed upon being the "Early Unwind Date"), this Transaction shall automatically terminate (the "Early Unwind"), on the Early
Unwind Date and (i) the Transaction and all of the respective rights and obligations of JPMorgan and Counterparty under the Transaction shall be cancelled and terminated and (ii) 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 the other party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date; provided that Counterparty shall
purchase from JPMorgan on the Early Unwind Date all Shares purchased by JPMorgan or one or more of its affiliates and reimburse JPMorgan for reasonable costs or expenses (including market losses) relating to the unwinding of its hedging activities in connection with
the Transaction (including reasonable losses or costs incurred as a result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position).  The amount of any such reimbursement shall be determined by JPMorgan in good faith
using commercially reasonable discretion and shall be supported by written evidence of the same.  JPMorgan shall notify Counterparty of such amount, shall provide written evidence of the same and Counterparty shall pay such amount in immediately available funds
on the Early Unwind Date.  JPMorgan and Counterparty represent and acknowledge to the other that, subject to the proviso included in this paragraph, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally
discharged.





     (f)     Transfer or Assignment.  Neither party may transfer any of its rights or obligations under the Transaction without the prior
written consent of the non-transferring party; provided that if (i) JPMorgan's "beneficial ownership" (within the meaning of Section 13 of the Exchange Act and rules promulgated thereunder) exceeds 7.5% of Counterparty's outstanding Shares or (ii) the quotient
of (x) the product of (a) the Number of Options and (b) the Option Entitlement divided by (y) the number of Counterparty's outstanding Shares (such quotient expressed as a percentage, the "Option Equity Percentage") exceeds 14.5%, JPMorgan 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 (i) the credit rating of
JPMorgan at the time of the transfer and (ii) if such debt is rated by Standard and Poor's Rating Group, Inc. ("S&P"), A- or higher by S&P, and if such debt is rated by Moody's Investor Service, Inc. ("Moody's"), A3 or higher by 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 agency rating mutually agreed by Counterparty and JPMorgan.  If after JPMorgan's commercially reasonable efforts, JPMorgan is unable to effect such a
transfer or assignment on pricing terms reasonably acceptable to JPMorgan and within a time period reasonably acceptable to JPMorgan of a sufficient number of Options to reduce (i) JPMorgan's "beneficial ownership" (within the meaning of Section 13 of the Exchange
Act and rules promulgated thereunder) to 7.5% of Counterparty's outstanding Shares or less or (ii) the quotient of (x) the product of (a) the Number of Options and (b) the Option Equity Percentage to 14.5% or less, JPMorgan may designate any Exchange Business Day as
an Early Termination Date with respect to a portion (the "Terminated Portion") of this Transaction, such that (i) its "beneficial ownership" following such partial termination will be equal to or less than 7.5% or (ii) the Option Equity Percentage following
such partial termination will be equal to or less than 14.5%.  In the event that JPMorgan so designates an Early Termination Date with respect to a portion of this 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 this Transaction and a Number of Options equal to the Terminated Portion, (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii)
such Transaction shall be the only Terminated Transaction (and, for the avoidance of doubt, the provisions of Section 9(m) shall apply to any amount that is payable by JPMorgan to Counterparty pursuant to this sentence as if Counterparty was not the Affected
Party).  Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing JPMorgan to purchase, sell, receive or deliver any shares or other securities to or from Counterparty, JPMorgan may designate any of its affiliates to
purchase, sell, receive or deliver such shares or other securities and otherwise to perform JPMorgan's obligations in respect of this Transaction and any such designee may assume such obligations.  JPMorgan shall be discharged of its obligations to Counterparty
to the extent of any such performance.





     (g)     Staggered Settlement.  If upon advice of counsel with respect to applicable legal and regulatory requirements, including any
requirements relating to JPMorgan's hedging activities hereunder, JPMorgan reasonably determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by JPMorgan on the Settlement Date for
the Transaction, JPMorgan may, by notice to Counterparty on or prior to any Settlement Date (a "Nominal Settlement Date"), elect to deliver the Shares on two or more dates (each, a "Staggered Settlement Date") as follows:





          (a)     in such notice, JPMorgan 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 the twentieth (20th) Exchange Business Day following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;





          (b)     the aggregate number of Shares that JPMorgan will deliver to Counterparty hereunder on all such Staggered Settlement
Dates will equal the number of Shares that JPMorgan would otherwise be required to deliver on such Nominal Settlement Date; and





          (c)     if the Net Share Settlement terms set forth above were to apply on the Nominal Settlement Date, then the Net Share
Settlement terms will apply on each Staggered Settlement Date, except that the Net Shares will be allocated among such Staggered Settlement Dates as specified by JPMorgan in the notice referred to in clause (a) above.





     (h)     Role of Agent.  Each party agrees and acknowledges that (i) J.P. Morgan Securities Inc., an affiliate of JPMorgan ("JPMSI"), has acted solely as
agent and not as principal with respect to this Transaction and (ii) JPMSI has no obligation or liability, by way of guaranty, endorsement or otherwise, in any manner in respect of this Transaction (including, if applicable, in respect of the settlement thereof).
Each party agrees it will look solely to the other party (or any guarantor in respect thereof) for performance of such other party's obligations under this Transaction.





     (i)     Dividends.  If at any time during the period from and including the Trade Date, to but excluding the Expiration Date, an ex-dividend date for a
cash dividend occurs with respect to the Shares (an "Ex-Dividend Date") in any quarterly dividend period of Counterparty, then the Calculation Agent will make a corresponding adjustment to any one or more of the Strike Price, Number of Options, the Option Entitlement
and/or any other variable relevant to the exercise, settlement or payment for the Transaction to preserve the fair value of the Options to JPMorgan after taking into account such dividend.





     (j)     Additional Termination Events.  Notwithstanding anything to the contrary in this Confirmation if an event of default with respect
to Counterparty shall occur under the terms of the Convertible Notes as set forth in Section 7.01 of the First Supplemental Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and,
with respect to such event of default (A) Counterparty shall be deemed to be the sole Affected Party and the Transaction shall be the sole Affected Transaction and (B) JPMorgan shall be the party entitled to designate an Early Termination Date pursuant to Section
6(b) of the Agreement.





     (k)     Amendments to Equity Definitions.  (i) Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting
from the fourth line thereof the word "or" after the word "official" and inserting a comma therefor, and (2) deleting the semi-colon at the end of subsection (B) thereof and inserting the following words therefor "or (C) at JPMorgan's option, the occurrence of any of
the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer."





(ii) Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing "either party may elect" with "JPMorgan may elect" and (2) replacing "notice to the other party" with "notice to Counterparty"
in the first sentence of such section.





     (l)     Setoff.  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, JPMorgan (and only JPMorgan)  shall have the right to set off any obligation that it may have to Counterparty under this Confirmation, including without limitation any obligation to make
any payment of cash or delivery of Shares to Counterparty, against any obligation Counterparty may have to JPMorgan under any other agreement between JPMorgan and Counterparty relating to Shares (each such contract or agreement, a "Separate Agreement"),
including without limitation any obligation to make a payment of cash or a delivery of Shares or any other property or securities. For this purpose, JPMorgan shall be entitled to convert any obligation (or the relevant portion of such obligation) denominated in one
currency into another currency at the rate of exchange at which it would be able to purchase the relevant amount of such currency, and to convert any obligation to deliver any non-cash property into an obligation to deliver cash in an amount calculated by reference
to the market value of such property as of the Early Termination Date, as determined by the Calculation Agent in its sole discretion; provided that in the case of a set-off of any obligation to release or deliver assets against any right to receive fungible
assets, such obligation and right shall be set off in kind and; provided further that in determining the value of any obligation to deliver Shares, the value at any time of such obligation shall be determined by reference to the market value of the Shares at
such time, as determined in good faith by the Calculation Agent.  If an obligation 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, 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.





     (m)     Alternative Calculations and Payment on Early Termination and on Certain  Extraordinary Events.  If in respect of this
Transaction, an amount is payable by JPMorgan 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 JPMorgan 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, a 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 JPMorgan, confirmed
in writing within one Currency Business Day, no later than 12:00 p.m. New York local time on the Merger 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 JPMorgan to satisfy its Payment Obligation by the Share Termination Alternative, JPMorgan 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.  For the avoidance of doubt, the parties agree that in calculating the Payment Obligation the
Determining Party may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.








	
     

	
Share Termination

 Alternative:

	
      

	
Applicable and means that JPMorgan shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the Payment Obligation would
otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable (the "Share Termination Payment Date"), in satisfaction of the Payment Obligation in the manner reasonably requested by
Counterparty free of payment.


		
                                             

		
                                                                                                                    


		
Share Termination Delivery

 Property:

	
   

	
A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price.  The Calculation Agent shall adjust the
Share Termination Delivery Property by replacing any fractional portion 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. 


		
                                             

		
		
Share Termination Unit

 Price:

		
The value to JPMorgan of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its good faith discretion by commercially reasonable means and notified by the
Calculation Agent to JPMorgan at the time of notification of the Payment Obligation; provided that in making such determination the Calculation Agent may take into account the unwinding of the hedging activities by JPMorgan in connection with the Transaction
and shall provide Counterparty written evidence of such determination upon Counterparty's written request.


		
                                             

		
		
Share Termination Delivery

 Unit:

		
One Share or, if a Merger Event has occurred and a corresponding adjustment to this Transaction has been made, a unit consisting of the number or amount of each type of property received by a holder of one Share
(without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Merger Event, as determined by the Calculation Agent.


		
                                             

		
		
Failure to Deliver:

		
Applicable


		
                                             

		
		
Other applicable provisions:

		
If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11, 9.12 and 10.5 (as modified above) of the Equity Definitions will be applicable, except that all references in such
provisions to "Physically-settled" shall be read as references to "Share Termination Settled" and all references to "Shares" shall be read as references to "Share Termination Delivery Units".  "Share Termination Settled" in relation to this Transaction means
that Share Termination Alternative is applicable to this Transaction.








     (n)     Governing Law.  New York law (without reference to choice of law doctrine).





     (o)     Waiver of Jury Trial.  Each party waives, to the fullest extent permitted by applicable law, any right it may have to a trial by
jury in respect of any suit, action or proceeding relating to this Transaction.  Each party (i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other party would not, in the event of such a
suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other party have been induced to enter into this Transaction, as applicable, by, among other things, the mutual waivers and certifications provided
herein.





     (p)     Registration.  Counterparty hereby agrees that if, in the good faith reasonable judgment of JPMorgan, the Shares ("Hedge
Shares") acquired by JPMorgan for the purpose of hedging its obligations pursuant to this Transaction cannot be sold in the public market by JPMorgan without registration under the Securities Act, Counterparty shall, at its election, either (i) in order to allow
JPMorgan to sell the Hedge Shares in a registered offering, make available to JPMorgan an effective registration statement under the Securities Act and enter into an agreement, in form and substance satisfactory to JPMorgan, substantially in the form of an
underwriting agreement for a registered secondary offering; provided,however, that if JPMorgan, 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 paragraph shall apply at the election of Counterparty, (ii) in order to allow JPMorgan 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 JPMorgan (in which case, the Calculation Agent shall make any adjustments to the terms of
this Transaction that are necessary, in its reasonable judgment, to compensate JPMorgan 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 JPMorgan at the
Reference Price on such Exchange Business Days, and in the amounts, requested by JPMorgan.





     (q)     Tax 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.





     (r)     Right to Extend.  JPMorgan may delay, no longer than reasonably necessary, any Settlement Date or any other date of delivery by
JPMorgan, with respect to some or all of the Options hereunder, if JPMorgan reasonably determines, in its discretion, that such extension is reasonably necessary to enable JPMorgan to effect purchases of Shares in connection with its hedging activity or settlement
activity hereunder in a manner that would, if JPMorgan were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal and regulatory requirements.





     (s)     Status of Claims in Bankruptcy.  JPMorgan acknowledges and agrees that this Confirmation is not intended to convey to JPMorgan
rights against Counterparty with respect to the Transaction that are senior to the claims of common stockholders of Counterparty in any U.S. bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit JPMorgan'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 JPMorgan's rights in respect of any transactions other than
the Transaction.





     (t)     Securities Contract; Swap Agreement.  The parties hereto intend for: (a) the Transaction to be a "securities contract" and a "swap
agreement" as defined in the Bankruptcy Code (Title 11 of the United States Code) (the "Bankruptcy Code"), and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560
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 Agreement with respect to the other party to constitute a "contractual right" as described in the
Bankruptcy Code; and (c) each payment and delivery of cash, securities or other property hereunder to constitute a "margin payment" or "settlement payment" and a "transfer" as defined in the Bankruptcy Code.





     (u)     Additional Provisions. Counterparty covenants and agrees that, as promptly as practicable following the public announcement of any
consolidation, merger and binding share exchange to which Counterparty is a party, or any sale of all or substantially all of Counterparty's assets, in each case pursuant to which the Shares will be converted into cash, securities or other property, Counterparty
shall notify JPMorgan in writing of the types and amounts of consideration that holders of Shares have elected to receive upon consummation of such transaction or event (the date of such notification, the "Consideration Notification Date"); provided that in no
event shall the Consideration Notification Date be later than the date on which such transaction or event is consummated.
