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 among Counterparty, MLI and Merrill Lynch, Pierce, Fenner & Smith Incorporated (the “Agent” or “MLPFS”) on the Trade Date specified below (the “Transaction”). This Confirmation constitutes a “Confirmation” as referred to in the 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 this 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, and form part of, an agreement in the 1992 form of the ISDA Master Agreement (Multicurrency Cross Border) (the “Master Agreement” or “Agreement”) as if we had executed an agreement in such form (but without any Schedule and with elections specified in the “ISDA Master Agreement” Section of this Confirmation) on the Trade Date. In the event of any inconsistency between the provisions of that Agreement and this Confirmation, this Confirmation will prevail for the purpose of this Transaction. The parties hereby agree that the Transaction evidenced by this Confirmation shall be the only Transaction subject to and governed by the Agreement.

If Counterparty elects to settle the Transaction by Cash Settlement, Counterparty represents and agrees that:
		(i) Counterparty is not, on the date of the Cash Settlement election, and will not be, on any day during the period from and including the first Expiration Date to and including the final Expiration Date, engaged in a distribution, as such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”); and

		Section 6.3(a) of the Equity Definitions is hereby amended by replacing clause (ii) in its entirety with “(ii) and Exchange Disruption, or” and inserting immediately following clause (iii) the phrase “; in each case that the Calculation Agent determines is material.”

Electing Party:		Counterparty

Default Settlement Method:		Net Physical Settlement
Net Physical Settlement:		In the event that the Counterparty elects to settle this Transaction by Net Physical Settlement, subject to subject to “Conditions Relating to Net Physical Settlement” below, Counterparty shall deliver to MLI on the Settlement Date a number of Shares (the “Delivered Shares”) equal to the Share Delivery Quantity, provided that in the event that the number of Shares calculated comprises any fractional Share, the Share Delivery Quantity shall be rounded up or down to the nearest integral number of Shares, only whole Shares shall be delivered and an amount in cash equal to the value of such fractional share shall be payable by the Counterparty to MLI in lieu of such fractional Share.
Share Delivery Quantity:		For each Exercise Date, a number of Shares, as calculated by the Calculation Agent, equal to the Net Physical Settlement Amount for such Exercise Date divided by the Settlement Price on the Valuation Date in respect of such Settlement Date plus an amount in cash in lieu of any fractional shares (based on the applicable Settlement Price).
Net Physical Settlement Amount:		For any Exercise Date, an amount equal to the product of (i) the Number of Warrants being exercised on the relevant Exercise Date, (ii) the Strike Price Differential for such Exercise Date and (iii) the Warrant Entitlement.
Strike Price Differential:		For any Valuation Date, (i) if the Settlement Price is greater than the Strike Price, an amount equal to the excess of such Settlement Price over the Strike Price for such Valuation Date or (ii) if such Settlement Price is less than or equal to the Strike Price, zero.
Settlement Date:		Settlement with respect to each Exercise Date shall occur on the third (3rd) Full Exchange Business Day following the final Valuation Date, provided that MLI shall have the right to request by prior written notice to Counterparty a Settlement Date with respect to any Exercise Date and the related Share Delivery Quantity that is three (3) Full Exchange Business Days following such Exercise Date. Such request shall not unreasonably be denied.

Conditions Relating to Net
Physical Settlement:		If, on or before the 30th Business Day following delivery of Shares hereunder, MLI notifies the Counterparty that MLI has reasonably determined after advice from counsel that there is a considered risk that such Shares are subject to restrictions on transfer in the hands of MLI pursuant to the rules and regulations promulgated under the Securities Act of 1933, as amended (“Securities Act”), then Counterparty shall either (i) deliver Shares that are covered by an effective registration statement of Counterparty for immediate resale by MLI or (ii) agree to deliver additional Shares in the amount and manner specified in sub-paragraph (B) or (C), as applicable, hereto.
		(A) If Counterparty elects to deliver Shares as described in above clause (i), then promptly following such notification from MLI
		(a) Counterparty shall afford MLI a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty that is customary in scope for underwritten offerings of equity securities registered for resale;
		(b) Counterparty shall promptly file and use commercially reasonable efforts to obtain the effectiveness of a registration statement for immediate resale (the “Registration Statement”) in form and content reasonably satisfactory to MLI and filed pursuant to Rule 415 under the Securities Act, and such prospectuses as MLI may reasonably request to comply with the applicable prospectus delivery requirements (the “Prospectus”) for the resale by MLI of such number of Shares as MLI 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 (1) all Delivered Shares have been sold by MLI, (2) MLI has advised Counterparty that it no longer requires that such Registration Statement be effective, (3) all remaining Delivered Shares could be sold by MLI without registration pursuant to Rule 144 promulgated under the Securities Act (the “Registration Period”) or (4) Counterparty has provided a legal opinion of nationally recognized counsel in form and substance satisfactory to MLI (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 MLI 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 MLI to be potentially deliverable by Counterparty in connection with Net Physical Settlement hereunder (not to exceed the Maximum Deliverable Share Amount) and shall be subject to the same suspension of sales during “blackout dates” as provided in the following paragraph; and
		(c) Counterparty will enter into a registration rights agreement with MLI in form and substance reasonably acceptable to MLI and Counterparty (“Registration Rights Agreement”), which agreement will contain among other things, customary representations and warranties and indemnification, restrictions on sales during “blackout dates”, provide for delivery of comfort letters, opinions of counsel, due diligence rights and other rights relating to the registration of a number of Shares equal to the number of Delivered Shares and other Shares deliverable hereunder up to the Maximum Deliverable Share Amount.
		(d) Counterparty shall promptly pay to MLI a $0.04 per Share fee with all Shares delivered in connection with Net Physical Settlement pursuant to a Registration Statement.
		(B) If Counterparty elects to deliver Shares as described in above clause (ii), then promptly following such notification from MLI

		(a) Counterparty shall afford MLI and any potential institutional purchaser of any Shares identified by MLI a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty that is customary in scope for private placements of equity securities by a publicly reporting company (if Counterparty is a publicly reporting company at such time) to institutional purchasers subject to execution of any customary confidentiality agreements;
		(b) Counterparty shall enter into an agreement (a “Private Placement Agreement”) with MLI on commercially reasonable terms in connection with the private placement of such Shares by Counterparty to MLI or an affiliate and the private resale of such shares by MLI or such affiliate, substantially similar to private placement purchase agreements customary for private placements of equity securities by a publicly reporting company (if Counterparty is a publicly reporting company at such time) to institutional purchasers, in form and substance commercially reasonably satisfactory to MLI and Counterparty, which Private Placement Agreement shall include reasonable and customary provisions relating to the indemnification of, and contribution in connection with the liability of, MLI and its affiliates, shall provide for the payment by Counterparty of all reasonable expenses in connection with such resale, including all reasonable and documented fees and expenses of counsel for MLI, shall contain representations, warranties and agreements of Counterparty reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales, and shall use reasonable best efforts to provide for the delivery of accountants’ “comfort letters” to MLI or such affiliate with respect to the financial statements and certain financial information contained in or incorporated by reference into any offering memorandum prepared for the resale of such Shares;
		(c) MLI shall sell the Delivered Shares in a commercially reasonable manner, in good faith and in accordance with the terms and limitations set forth in the Private Placement Agreement until the amount received by MLI for the sale of the Shares (the “Proceeds Amount”) is equal to the Net Physical Settlement Amount. Any remaining Delivered Shares shall be returned to Counterparty. If the Proceeds Amount is less than the Net Physical Settlement Amount, Counterparty shall promptly deliver upon notice from MLI additional Shares to MLI until the dollar amount from the sale of such Shares by MLI equals the difference between the Net Physical Settlement Amount and the Proceeds Amount. In no event shall Counterparty be required to deliver to MLI a number of Shares greater than the Maximum Deliverable Share Amount.
		(C) Notwithstanding the foregoing: (I) if Counterparty has elected to deliver Shares as described in clause (i) above and either (a) Counterparty does not provide for the sale of the Shares under the Registration Statement as provided in the Registration Rights Agreement or (b) some Shares cannot be registered under the Registration Statement due to Rule 415(a)(4) under the Securities Act, then the provisions of sub-paragraph (B) shall apply to the extent Counterparty has not satisfied its obligations hereunder by the delivery of Shares pursuant to sub-paragraph (A). (II) If sub-paragraph (B) is applicable and Counterparty fails to satisfy its obligations under such sub-paragraph (B), then Counterparty may deliver unregistered Shares of equivalent value to the Net Physical Settlement Amount (or, if applicable, the unsatisfied portion thereof). The value of any unregistered Shares so delivered shall be discounted to reflect an appropriate liquidity discount (determined by MLI in a commercially reasonable manner). (III) If some or all of the Delivered Shares cannot be used to close out stock loans in the shares of Counterparty entered into to establish or maintain short positions by MLI in connection with this Transaction without a prospectus being

		required by applicable law to be delivered to such lender, then the value of any such Delivered Shares shall reflect an additional discount as determined by MLI in good faith and in a commercially reasonable manner and the number of Shares deliverable shall be correspondingly increased, except where, pursuant to paragraph (A)(d) above, a $0.04 fee has been paid or is payable in respect of such Delivered Shares. MLI 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. In no event shall Counterparty be required to top-up any delivery in cash or deliver to MLI a number of Shares greater than the Maximum Deliverable Share Amount.
Limitations on Net Physical
Settlement by Counterparty:		Notwithstanding anything herein or in the Agreement to the contrary, the number of Shares that may be delivered at settlement by Counterparty shall not exceed the product of 2.0 times the initial Number of Warrants at any time (“Maximum Deliverable Share Amount”), as adjusted by the Calculation Agent to account for any subdivision, stock-split, reclassification or similar dilutive event with respect to the Shares.
		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 (i) Counterparty shall not take any action of corporate governance or otherwise to reduce the number of Available Shares below the Maximum Deliverable Share and (ii) Counterparty shall use its reasonable efforts to cause the number of Available Shares at all times to be greater than 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.
Dividends:
Dividends:		If at any time during the period from and including the Trade Date, to but excluding the final Expiration Date, an ex-dividend date for a cash dividend occurs with respect to the Shares (an “Ex-Dividend Date”), and that dividend is different from the Regular Dividend on a per Share basis, then the Calculation Agent will, in its reasonable discretion, adjust the Strike Price, the Number of Warrants, the Daily Number of Warrants, the Warrant Entitlement and any other variable it deems appropriate to preserve the fair value of the Warrant after taking into account such dividend.
Regular Dividend:		Initially USD 0.06 per Share per quarter in respect of the Shares. In the event that, in any quarter, a regular quarterly Ex-Dividend Date occurs for which the amount of the corresponding cash dividend is different (the “New Dividend Amount”) from the Regular Dividend or no Ex-Dividend Date occurs (in which case the New Dividend Amount shall be zero), then following the adjustment by the Calculation Agent pursuant to “Dividends” above, the Regular Dividend shall equal the New Dividend Amount.
Extraordinary Dividends:		Any dividend other than Regular Dividends. For the avoidance of doubt, if more than one Ex-Dividend Date occurs in a quarter, the Calculation Agent shall

		designate any cash dividend other than a Regular Dividend as an Extraordinary Dividend and will, in its reasonable discretion, adjust the Strike Price, the Number of Warrants, the Daily Number of Warrants, the Warrant Entitlement and any other variable it deems appropriate to preserve the fair value of the Warrant after taking into account such dividend.

Method of Adjustment:		Calculation Agent Adjustment
Extraordinary Events:
Consequences of Merger Events:		(a) Share-for-Share: Cancellation and Payment (subject to satisfaction by delivery of Shares as set forth in “Early Termination” below).

Determining Party:		As specified under “Early Termination”
		For the avoidance of doubt, with respect to any Extraordinary Events hereunder, upon the occurrence of Cancellation and Payment in whole or in part, the parties agree that, notwithstanding anything to the contrary in the Equity Definitions, the provisions set forth in the Early Termination section below shall apply.

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 set forth in subsection (c) under “Additional Agreements, Representations and Covenants of Counterparty, etc.” below.
Early Termination:		Notwithstanding Section 6(e) of the Agreement or Sections 12.7 or 12.8 of the Equity Definitions, if, with respect to the Transaction contemplated hereunder, (A) an Early Termination Date with respect to any Event of Default or any Termination Event, (B) a Merger Date with respect to any Merger Event or Tender Offer Date with respect to a Tender Offer, (C) a Closing Date with respect to an event described in Section 12.6 of the Equity Definitions, or (D) date as of which the Transaction is, or is deemed to have been, terminated or cancelled as a result of an applicable Additional Disruption Event (any such date, the “Relevant Date”) shall occur, then in lieu of calculating any payments hereunder pursuant to Section 6(e) of the Agreement or Sections 12.7 or 12.8 of the Equity Definitions, as applicable, (if a calculation under such sections would otherwise be required), the Calculation Agent shall determine in a commercially reasonable manner, the number of Shares deliverable by Counterparty to MLI on the following basis:
		(1) such Relevant Date shall be the sole Exercise Date hereunder and Automatic Exercise shall be applicable to the unexercised Number of Warrants (the “Unexpired Number”);
		(2) the Settlement Method shall be Net Share Settlement;
		(3) Counterparty shall deliver to MLI the Net Share Settlement Amount on the Settlement Date with respect to such Relevant Date (“Early Termination Stock Settlement”); provided that, if Counterparty is delivering Shares as a result of a Merger Event, the Settlement Date for such delivery will be immediately prior to the effective time of the Merger Event and the Shares will be deemed delivered at such time such that MLI will be a holder of the Shares prior to such effective time;
		(4) Net Share Settlement Amount shall mean (subject to the Maximum Deliverable Share Amount) a number of Shares equal to the sum of (A) the Share Delivery Quantity (as defined herein) and (B) the product of (x) the additional Shares per Warrant (the “Additional Shares”) determined by reference to the table attached as Annex A hereto based on the date on which such Relevant Date occurs and the VWAP Price on such date, (y) the Unexpired Number, and (z) the Warrant Entitlement;
		(5) with respect to the determination of Additional Shares, if the actual VWAP Price is between two VWAP Price amounts in the table or the Relevant Date is between two Relevant Dates in the table, the Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower VWAP Price amounts and the two nearest Relevant Dates, as applicable, based on a 365-day year; and
		(6) with respect to any adjustment to the terms of the Transaction, the Calculation Agent, shall correspondingly adjust the Additional Shares and/or the VWAP Prices (each as set forth in the table in Annex A hereto) as of any date of such adjustments; provided, for the avoidance of doubt, that any such adjustments shall be made consistently with the applicable provisions of this Confirmation and the Equity Definitions. For the avoidance of doubt, any

		calculations made by the Calculation Agent with respect to this Transaction pursuant to Section 11.2(c), Section 12.2(d) or Section 12.3(c) of the Equity Definitions may take into account the Calculation Agent’s determination of the fair market value of the Shares under the then prevailing circumstances.
		On or prior to the Relevant Date, if so requested by MLI upon advice of counsel, Counterparty shall (subject to its right to make the election described in the immediately succeeding paragraph) enter into a registration rights agreement with MLI in form and substance reasonably acceptable to MLI and Counterparty (which agreement will contain among other things, reasonable customary representations and warranties and indemnification, restrictions on sales during “blackout dates”, and provide for delivery of comfort letters, opinions of counsel, due diligence rights and other customary rights) and Counterparty shall satisfy the conditions contained therein and Counterparty shall file and use its commercially reasonable efforts to obtain the 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 MLI such Prospectuses as MLI may reasonably request to comply with the applicable prospectus delivery requirements for the resale by MLI of such number of Shares as MLI 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) MLI has advised Counterparty that it no longer requires that such Registration Statement be effective, (iii) all remaining Shares could be sold by MLI without registration pursuant to Rule 144 promulgated under the Securities Act (the “Termination Registration Period”) or (iv) Counterparty has provided a legal opinion of nationally recognized counsel in form and substance satisfactory to MLI (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 MLI and not subject to any legend restricting transferability. 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 MLI 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 Termination Registration Period Counterparty shall represent that each of its filings under the Securities Act, 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, they do not contain any untrue statement of a material fact or omission of a material fact required to be stated therein or necessary to make the statements made, in the light of the circumstances under which they were made, not misleading.
		If Counterparty elects not to deliver Shares subject to an effective Registration Statement (or if some or all of the Shares delivered cannot be used to close out stock loans in the shares of Counterparty entered into to establish or maintain short positions by MLI in connection with this Transaction without a prospectus being required by applicable law to be delivered to such lender), the provisions of sub-paragraphs (B) and (C) set forth above under “Conditions Relating to Net Physical Settlement” shall apply, mutatis mutandis, as if the Net Physical Settlement Amount were the Transaction Early Termination Amount. “Transaction Early Termination Amount” means the Net Share Settlement Amount multiplied by the Settlement Price. In no event shall Counterparty be

		required to deliver to MLI a number of Shares greater than the Maximum Deliverable Share Amount.
Compliance With Securities Laws:		Counterparty represents and agrees that it has complied, and will comply, in connection with this 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 promulgated thereunder, including, without limitation, Rule 10b-5 and 13e and Regulation M under the Exchange Act.
		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, each party represents and warrants to the other party that (i) it has the financial ability to bear the economic risk of entering into 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 this Transaction and the Shares is restricted under this Confirmation, the Securities Act and state securities laws.
		Counterparty further represents and warrants that:
		(a) 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 Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for Shares);
		(b) Counterparty represents and acknowledges that as of the date hereof and without limiting the generality of Section 13.1 of the Equity Definitions, MLI 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;
		(c) Counterparty is not, and after giving effect to the Transaction contemplated hereby, will not be, an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.
		(d) As of the Trade Date and each date on which a payment or delivery is made by Counterparty hereunder, (i) the assets of Counterparty at their fair valuation exceed the liabilities of Counterparty, including contingent liabilities; (ii) the capital of Counterparty is adequate to conduct its business; and (iii) Counterparty has the ability to pay its debts and other obligations as such obligations mature and does not intend to, or believe that it will, incur debt or other obligations beyond its ability to pay as such obligations mature.

For the avoidance of doubt, the parties acknowledge and agree that MLI’s rights with respect to any other claim arising from this Transaction prior to Counterparty’s bankruptcy shall remain in full force and effect and shall not be otherwise abridged or modified in connection herewith.
Set-Off:		Each party waives any and all rights it may have to set-off, whether arising under any agreement, applicable law or otherwise.
Transfer:		Neither party may transfer its rights and delegate its obligations under this Transaction; provided, however, that MLI may assign its rights and delegate its obligations hereunder, in whole or in part, to any other person with prior consent of the Counterparty not to be unreasonably withheld. Either party may assign its rights and delegate its obligations hereunder, in whole or in part, to any other person (an “Assignee”) with the prior consent of the other party, effective (the “Transfer Effective Date”) upon delivery to such party of an executed acceptance and assumption by the Assignee (an “Assumption”) of the transferred obligations of the assigning party under this Transaction (the “Transferred Obligations”). Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing MLI to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, MLI may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities and otherwise to perform MLI’s obligations in respect of this Transaction and any such designee may assume such obligations. MLI shall be discharged of its obligations to Counterparty to the extent of any such performance.
Regulation:		MLI is regulated by The Securities and Futures Authority Limited.
Indemnity:		Seller (the “Indemnifying Party”) agrees to indemnify MLI, its Affiliates and their respective directors, officers, agents and controlling parties (each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities, joint and several, to which such Indemnified Party may become subject because of a breach of any representation or covenant hereunder, in the Agreement or any other agreement relating to the Agreement or Transaction and will reimburse Indemnified Party for all reasonable expenses (including reasonable legal fees and expenses) as they are incurred in connection with the investigation of, preparation for, or defense of, any pending or threatened claim or any action or proceeding arising therefrom, whether or not

		such Indemnified Party is a party thereto. The Indemnifying Party will not be liable under the foregoing Indemnity provision to the extent that any loss, claim, damage, liability or expense is found in a final judgment by a court to have resulted from an Indemnified Party’s gross negligence or willful misconduct.
Right to Extend:		MLI may postpone, in whole or in part, any Expiration Date or any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which event the Calculation Agent shall make appropriate adjustments to the Daily Number of Warrants with respect to one or more Expiration Dates) if MLI determines, in its commercially reasonable judgment, that such extension is reasonably necessary or appropriate to preserve MLI’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions or to enable MLI to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if MLI were Issuer or an affiliated purchaser of Issuer, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to MLI.

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

(a)

Counterparty hereby represents and warrants to MLI, on each day from the Trade Date to and including the earlier of (i) March 17, 2007, and (ii) the date by which MLI is able to initially complete a hedge of its position created by this 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 pursuant to transactions or arrangements which have been approved by MLI or an affiliate of MLI; 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.

(b)		No collateral shall be required by either party for any reason in connection with this Transaction.
(c)		Notwithstanding anything to the contrary herein, MLI shall not be entitled to exercise any Warrant or take delivery of any Shares deliverable hereunder, and Automatic Exercise shall not apply with respect to any Warrant, to the extent (but only to the extent) that after such receipt of any Shares upon the exercise of such Warrant or otherwise hereunder MLI, or its ultimate parent entity would, directly or indirectly, be the beneficial owner (as such term is defined for purposes of Section 13(d) of the Exchange Act) at any time of more than 8.0 percent of the class of the Counterparty’s outstanding equity securities that is comprised of the Shares (an “Excess Share Owner”).
		MLI shall provide prior notice to Counterparty if the exercise of any Warrant or delivery of Shares hereunder would cause MLI to become, directly or indirectly, an Excess Share Owner; provided that the failure of MLI to provide such notice shall not alter the effectiveness of the provisions set forth in the preceding sentence and any purported exercise or delivery in violation of such provisions shall be void and have no effect. If any delivery owed to MLI hereunder is not made, in whole or in part, as a result of this provision, Counterparty’s obligation to make such delivery shall not be extinguished and Counterparty shall make such delivery as promptly as practicable after MLI gives notice that such delivery would not result in MLI being an Excess Share Owner; provided that any such notice must be delivered by MLI no later than September 30, 2012.
		If MLI is not entitled to exercise any Warrant because such exercise would cause MLI to become, directly or indirectly, an Excess Share Owner and MLI thereafter disposes of Shares owned by it or any action is taken that would then permit MLI to exercise such Warrant without such exercise causing it to become,

directly or indirectly, an Excess Share Owner, then MLI shall provide notice of the taking of such action to Counterparty and such Warrant shall then become exercisable by MLI to the extent such Warrant is otherwise or had otherwise become exercisable hereunder; provided that any such notice must be delivered by MLI no later than September 30, 2012. In such event, the Expiration Date with respect to such Warrant shall be the date on which Counterparty receives such notice from MLI, 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 subsection); provided that the related Net Physical Settlement Amount shall be the same as the Net Physical Settlement Amount but for the provisions of this subsection. In addition, within 30 calendar days of a Settlement Date, Counterparty shall use its reasonable efforts to refrain from activities that could reasonably be expected to result in MLI’s ownership of Shares exceeding 10% of all issued and outstanding Shares.

Matters Relating to Agent:

1.		MLPFS will be responsible for the operational aspects of the Transactions effected through it, such as record keeping, reporting, and confirming Transactions to Counterparty and MLI;
2.		Unless MLI is a “major U.S. institutional investor,” as defined in Rule 15a-6 of the Exchange Act, neither Counterparty not MLI will contact the other without the direct involvement of MLPFS;
3.		MLPFS’s sole role under this Agreement and with respect to any Transaction is as an agent of Counterparty and MLI on a disclosed basis and MLPFS shall have no responsibility or liability to Counterparty or MLI hereunder except for gross negligence or willful misconduct in the performance of its duties as agent. MLPFS is authorized to act as agent for MLI, but only to the extent expressly required to satisfy the requirements of Rule 15a-6 under the Exchange Act in respect of the Options described hereunder. MLPFS shall have no authority to act as agent for Counterparty generally or with respect to transactions or other matters governed by this Agreement, except to the extent expressly required to satisfy the requirements of Rule 15a-6 or in accordance with express instructions from Counterparty.

EXHIBIT A

GUARANTEE OF MERRILL LYNCH & CO., INC.

     FOR VALUE RECEIVED, receipt of which is hereby acknowledged, MERRILL LYNCH & CO., INC., a corporation duly organized and existing under the laws of the State of Delaware (“ML & Co.”), hereby unconditionally guarantees to Mylan Laboratories Inc. (the “Company”), the due and punctual payment of any and all amounts payable by Merrill Lynch International, a company organized under the laws of England and Wales (“ML”), under the terms of the Confirmation of OTC Warrant Transaction between the Company and ML (ML as Buyer), dated as of March 1, 2007 (the “Confirmation”), including, in case of default, interest on any amount due, when and as the same shall become due and payable, whether on the scheduled payment dates, at maturity, upon declaration of termination or otherwise, according to the terms thereof. In case of the failure of ML punctually to make any such payment, ML & Co. hereby agrees to make such payment, or cause such payment to be made, promptly upon demand made by the Company to ML & Co.; provided, however that delay by the Company in giving such demand shall in no event affect ML & Co.’s obligations under this Guarantee. This Guarantee shall remain in full force and effect or shall be reinstated (as the case may be) if at any time any payment guaranteed hereunder, in whole or in part, is rescinded or must otherwise be returned by the Company upon the insolvency, bankruptcy or reorganization of ML or otherwise, all as though such payment had not been made.

     ML & Co. hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Confirmation; the absence of any action to enforce the same; any waiver or consent by the Company concerning any provisions thereof; the rendering of any judgment against ML or any action to enforce the same; or any other circumstances that might otherwise constitute a legal or equitable discharge of a guarantor or a defense of a guarantor. ML covenants that this guarantee will not be discharged except by complete payment of the amounts payable under the Confirmation. This Guarantee shall continue to be effective if ML merges or consolidates with or into another entity, loses its separate legal identity or ceases to exist.

     ML & Co. hereby waives diligence; presentment; protest; notice of protest, acceleration, and dishonor; filing of claims with a court in the event of insolvency or bankruptcy of ML; all demands whatsoever, except as noted in the first paragraph hereof; and any right to require a proceeding first against ML.

     ML & Co. hereby certifies and warrants that this Guarantee constitutes the valid obligation of ML & Co. and complies with all applicable laws.

     This Guarantee shall be governed by, and construed in accordance with, the laws of the State of New York.

     This Guarantee may be terminated at any time by notice by ML & Co. to the Company given in accordance with the notice provisions of the Confirmation, effective upon receipt of such notice by the Company or such later date as may be specified in such notice; provided, however, that this Guarantee shall continue in full force and effect with respect to any obligation of ML under the Confirmation arising before or after such termination.

     This Guarantee becomes effective concurrent with the effectiveness of the Confirmation, according to its terms.

     IN WITNESS WHEREOF, ML & Co. has caused this Guarantee to be executed in its corporate name by its duly authorized representative.
