Dear Sir / Madam:

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 purposes of the Equity Definitions and a “Swap Transaction” for the purposes of the Swap Definitions.

     This Confirmation evidences a complete binding agreement between you and us as to the terms of the Transaction to which this Confirmation relates.

b.	it will not engage in, or be engaged in, any “distribution,” as such term is defined in Regulation M promulgated under the Exchange Act, other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M (it being understood that Buyer makes no representation pursuant to this clause in respect of any action or inaction taken by Seller or any Underwriter of the Reference Notes); and

Notwithstanding anything herein or in the Agreement to the contrary, the aggregate number of Shares that Counterparty may be required to deliver to MLI under this Transaction shall not exceed 12,263,103, as adjusted by Calculation Agent to account for any subdivision, stock-split, stock combination, reclassification or similar dilutive or anti-dilutive event with respect to the Shares
3.	Notwithstanding any provision in the Note Indenture, this Confirmation or the Agreement to the contrary, each of the “applicable Conversion Rate” (as such term is used in the Note Indenture), the Net Share Settlement Amount, the Net Cash Settlement Amount and any other amount computed hereunder by reference to the applicable Conversion Rate shall be determined without regard to any discretionary adjustment to the Conversion Rate by Counterparty.

(i) such Relevant Date shall be the sole Exercise Date hereunder and Automatic Exercise shall be applicable;

(ii) the Settlement Method shall be Net Share Settlement and the provisions set forth above under “Net Share Settlement” shall apply (but without regard to subsection (ii) thereof, or any right of the Counterparty to elect to deliver cash in lieu of Remaining Shares pursuant to the Note Indenture, or any requirement of Counterparty to deliver an Exercise Notice) as if a Conversion Date had occurred, the Conversion Amount were the aggregate principal amount of the Reference Notes then outstanding, and the Remaining Shares were equal to (X) the excess, if any, of (a) the VWAP Price on the Relevant Date multiplied by the applicable Conversion Rate over (b) $1,000; divided by (Y) the VWAP Price on the Relevant Date;provided that, if the Shares have been converted into other securities or property in connection with an Extraordinary Event, Seller may deliver a number or amount of such other securities or property as a holder of the number of Shares that would otherwise be deliverable under this paragraph would be entitled to receive upon the consummation or closing of such Extraordinary Event. “VWAP Price” means, on any date, the per Share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page MYL.N <equity> VAP (or any successor thereto) in respect of the period from 9:45 a.m. to 3:45 p.m. (New York City time) on such date (or if such volume-weighted average price is unavailable, the market value of one Share (or, if applicable, the value per Share of the consideration paid or delivered to holders of Shares at the time of an Extraordinary Event) on such date, as determined by the Calculation Agent)[; provided that if the scheduled weekday closing time of the Exchange for any such date is later than 4:00 p.m. (without regard to after hours or any other trading outside of the regular trading session hours) the VWAP Price shall be calculated for such Valuation Date from 9:45 a.m. until 15 minutes prior to such later closing time of the Exchange];

(iii) the Seller shall deliver an additional number of Shares equal to the product of (X) the Applicable Portion, (Y) the number of Reference Notes each having principal value of $1,000 then outstanding and (Z)

7

the applicable number of Shares (the “Scheduled 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;

(iv) with respect to the determination of Scheduled 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 Scheduled Shares shall be determined by a straight-line interpolation between the number of Scheduled 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

(v) with respect to any adjustment to the terms of the Transaction, the Calculation Agent, shall correspondingly adjust the Scheduled 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.

(vi) the Settlement Date shall be the date that falls one Settlement Cycle following the Relevant Date.

1.

Amendment Event. Notwithstanding anything to the contrary herein, each Amendment Event (as defined below), if any, shall be disregarded for the purposes of determining the obligations of the parties hereunder, including the obligations of MLI to deliver Shares and/or cash. Accordingly, references to the “Note Indenture” herein shall be deemed to exclude any amendments to the Note Indenture that would have the effect of altering the obligations of the parties hereunder.

“Amendment Event” means that the Counterparty, without the prior consent of Seller, amends, modifies, supplements or obtains a waiver of (a) any term of the Note Indenture or the Reference Notes relating to the principal amount, coupon, maturity or repurchase obligation of the Counterparty, (b) any material term relating to conversion of the Reference Notes (including changes to the conversion price, conversion settlement dates or conversion conditions) or (c) any term that would require consent of the holders of 100% of the principal amount of the Reference Notes to amend.

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

2.

Repayment Event.If a Repayment Event (as defined below) occurs, MLI shall have the right to designate an Early Termination Date pursuant to Section 6(b) of the Agreement with respect to this Transaction to the extent of the principal amount of Reference Notes that cease to be outstanding as a result of such Repayment Event and, notwithstanding anything to the contrary herein, no payments shall be required under this Agreement in connection with such Repayment Event with respect to the principal amount of Reference Notes repurchased, repaid, exchanged or cancelled in connection with such Repayment Event.

“Repayment Event” means that (a) any Reference Notes are repurchased (whether in connection with or as a result of a change of control, howsoever defined, or for any other reason other than as a result of or in

8

connection with a conversion) by the Counterparty, (b) any Reference Notes are delivered to the Counterparty in exchange for delivery of any property or assets of the Counterparty or any of its subsidiaries (howsoever described), other than as a result of and in connection with a Conversion Date, (c) any principal of any of the Reference Notes is repaid prior to the Final Maturity Date (as defined in the Note Indenture) (whether following acceleration of the Reference Notes or otherwise), provided that no payments of cash made in respect of the conversion of a Reference Note shall be deemed a payment of principal under this clause (c), (d) any Reference Notes are exchanged by or for the benefit of the holders thereof for any other securities of the Counterparty or any of its Affiliates (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction or (e) any of the Reference Notes is surrendered by Counterparty to the trustee for cancellation, other than registration of a transfer of such Reference Notes or as a result of and in connection with a Conversion Date.

Staggered Settlement:

If Seller determines reasonably and in good faith that the number of Shares required to be delivered to Buyer hereunder on any Settlement Date would exceed 8.0% of all outstanding Shares, then Seller may, by notice to Buyer on or prior to such Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares comprising the related Net Share Settlement Amount on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date as follows:

1. in such notice, Seller will specify to Buyer the related Staggered Settlement Dates (the first of which will be such Nominal Settlement Date and the last of which will be no later than twenty (20) Trading Days following such Nominal Settlement Date) or delivery times and how it will allocate the Shares it is required to deliver hereunder among the Staggered Settlement Dates or delivery times;

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

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

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

Disposition of Hedge Shares:

Seller shall conduct its hedging activities in connection with the Transaction in a manner that it believes, based on its reasonable judgment, will not require Counterparty to register under the Securities Act or any state securities laws the Shares (the “Hedge Shares”) acquired by Seller for the purpose of hedging its obligations pursuant to the Transaction. In addition, Counterparty hereby agrees that if, in the reasonable judgment of Seller based on advice of counsel, the Hedge Shares cannot be sold in the U.S. public market by Seller without registration under the Securities Act, Counterparty shall, at its election: (i) in order to allow Seller to sell the Hedge Shares in a registered offering, use commercially reasonable efforts to make available to Seller an effective registration statement under the Securities Act to cover the resale of such Hedge Shares and (a) enter into an agreement, in form and substance satisfactory to Seller and Counterparty, substantially in the form of an underwriting agreement for a registered offering, (b) provide accountant’s “comfort” letters in customary form for registered offerings of equity securities, (c) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Seller, (d) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (e) afford Seller a reasonable opportunity to conduct a “due diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities registered for resale;provided, however, that if Seller, in its sole reasonable discretion, is not satisfied with access to

9

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 (iii) of this Section shall apply at the election of Counterparty; (ii) in order to allow Seller 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 by a publicly reporting company (if Counterparty is a publicly reporting company at such time) to institutional purchasers, in form and substance satisfactory to Seller and Counterparty, including reasonable and customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to Seller, due diligence rights (for Seller or any designated buyer of the Hedge Shares from Seller), opinions and certificates and such other documentation as is customary for private placements agreements, all reasonably acceptable to Seller (in which case, the Calculation Agent acting in a commercially reasonable manner shall make any adjustments to the terms of the Transaction that it determines are necessary to reflect an appropriate discount from the public market price of the Shares due to the lack of liquidity thereof); or (iii) purchase the Hedge Shares from Seller at the VWAP Price on such Exchange Business Days, and in the amounts, requested by Seller.

Repurchase Notices:

Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Seller a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the Notice Percentage as determined on such day is (i) greater than 6% and (ii) greater by 0.5% than the Notice Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Notice Percentage as of the date hereof). In the event that Counterparty fails to provide Seller with a Repurchase Notice on the day and in the manner specified in this section, then Counterparty agrees to indemnify and hold harmless Seller, its affiliates and their respective directors, officers, employees, agents and controlling persons (Seller and each such person being an “Indemnified Party”) from and against any and all losses, claims, damages and liabilities (or actions in respect thereof), joint or several, to which such Indemnified Party may become subject under applicable securities laws, including without limitation, Section 16 of the Exchange Act, relating to or arising out of such failure. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all reasonable and documented expenses (including reasonable counsel fees and expenses) as they are incurred (after notice to Counterparty) in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. This indemnity shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and delegation of the Transaction made pursuant to this Confirmation or the Agreement shall inure to the benefit of any permitted assignee of Seller. Counterparty will not be liable under this 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 MLI’s gross negligence or willful misconduct. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, (i) the numerator of which is the product of (a) the Applicable Portion, (b) the number of outstanding Reference Notes and (c) the number of Shares per Reference Note equal to the Conversion Rate (as defined in the Note Indenture) and (ii) the denominator of which is the number of Shares outstanding on such day.

Conversion Rate Adjustment Notices:

Counterparty shall provide to MLI written notice (such notice, a “Conversion Rate Adjustment Notice”) prior to consummating or otherwise executing or engaging in any transaction or event (a “Conversion Rate Adjustment Event”) that would lead to an increase in the Conversion Rate (as such term is defined in the Indenture), which Conversion Rate Adjustment Notice shall set forth the new, adjusted Conversion Rate after giving effect to such Conversion Rate Adjustment Event (the “New Conversion Rate”). Each Conversion Rate Adjustment Notice shall be delivered to MLI at or prior to the deadline contained in Section 4.09 of the Indenture for the related notices under the Indenture. In connection with the delivery of any Conversion Rate Adjustment Notice to MLI, (x)

10

Counterparty shall, concurrently with or prior to such delivery, publicly announce and disclose the Conversion Rate Adjustment Event or (y) Counterparty shall, concurrently with such delivery, represent and warrant that the information set forth in such Conversion Rate Adjustment Notice does not constitute material non-public information with respect to Counterparty or the Shares.

Compliance with Securities Laws:	Each party represents and agrees that, in connection with this Transaction and all related or contemporaneous sales and purchases of Shares by either party, Buyer, or in the case of Seller, the person(s) that directly influences the specific trading decisions of Seller, has complied and will comply with the applicable provisions of the Securities Act of 1933, as amended (the “Securities Act”), and the Exchange Act, and the rules and regulations each thereunder, including, without limitation, Rules 10b-5, 10b-18 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.
	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, Buyer represents and warrants to Seller 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.
	Buyer further represents:
	(a) Buyer 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) Buyer acknowledges that as of the date hereof and without limiting the generality of Section 13.1 of the Equity Definitions, Seller is not making any representations or warranties with respect to the treatment of the Transaction under FASB Statements 149 or 150, EITF Issue No. 00-19 (or any successor issue statements) or under FASB’s Liabilities & Equity Project.

	Accounts for deliveries of Shares:	[to be advised by Buyer or Seller, as applicable]
Bankruptcy Rights:	In the event of Buyer’s bankruptcy, Seller’s rights in connection with this Transaction shall not exceed those rights held by common shareholders. For the avoidance of doubt, the parties acknowledge and agree that Seller’s rights with respect to any other claim

11

	arising from this Transaction prior to Buyer’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.
Collateral:	None.
Transfer:	Buyer shall have the right to assign its rights and delegate its obligations hereunder with respect to any portion of this Transaction, subject to Seller’s consent, such consent not to be unreasonably withheld; provided that such assignment or transfer shall be subject to receipt by Seller of opinions and documents reasonably satisfactory to Seller and effected on terms reasonably satisfactory to the Seller with respect to any legal and regulatory requirements relevant to the Seller; provided further that Buyer shall not be released from its obligation to deliver any Exercise Notice or its obligations pursuant to “Disposition of Hedge Shares”, “Repurchase Notices” or “Conversion Rate Adjustment Notices” above, and Buyer shall be responsible for all reasonable costs and expenses, including reasonable counsel fees, incurred by Seller in connection with any such transfer or assignment. Seller may, with Buyer’s consent (such consent not to be unreasonably withheld), transfer or assign all or any part of its rights or obligations under this Transaction to any third party, in order to transfer or assign a sufficient portion of this Transaction to reduce (i) Seller’s “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and rules promulgated thereunder) to 7.5% of Buyer’s outstanding Shares or less or (ii) the Notice Percentage to 8.5% or less. If after Seller’s commercially reasonable efforts, Seller is unable to effect such a transfer or assignment on pricing terms reasonably acceptable to Seller and within a time period reasonably acceptable to Seller (including without limitation where such inability of Seller is due to Buyer’s withholding of consent to such transfer or assignment), Seller 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 Notice Percentage following such partial termination will be equal to or less than 8.5%. In the event that Seller so designates an Early Termination Date with respect to a portion of this Transaction, the provisions set forth above under paragraph 4 of “Additional Agreements, Representations and Covenants of Buyer, Etc.” shall apply in lieu of Section 6(d)(ii) and 6(e) of the Agreement as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to this Transaction but whose Applicable Portion was equal to the product of the Applicable Portion of this Transaction and the Terminated Portion and (ii) such Transaction were the only Terminated Transaction.
	MLI may assign and delegate its rights and obligations under this Transaction to any subsidiary of ML & Co. (the “Assignee”) by notice specifying the effective date of such transfer (“Transfer Effective Date”) and including an (i) executed acceptance and assumption by the Assignee of such rights and obligations and (ii) evidence reasonably satisfactory to Counterparty that such obligations of the Assignee are guaranteed by ML & Co. to substantially the same extent as MLI’s obligations under this Transaction; provided that (i) Counterparty will not, as a result of such transfer, be required to pay to the Assignee an amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement (except in respect of interest under Section 2(e), 6(d)(ii), or 6(e)) greater than the amount in respect of which Counterparty would have been required to pay to MLI in the absence of such transfer; and (ii) the Assignee will not, as a result of such transfer, be required to withhold or deduct on account of a Tax under Section 2(d)(i) of the Agreement (except in respect of interest under Section 2(e), 6(d)(ii), or 6(e)) an amount in excess of that which MLI would have been required to withhold or deduct in the

12

	absence of such transfer, unless the Assignee would be required to make additional payments pursuant to Section 2(d)(i)(4) of the Agreement corresponding to such excess. On the Transfer Effective Date, (a) MLI shall be released from all obligations and liabilities arising under this Transaction; and (b) the assigned and delegated rights and obligations under this Transaction shall cease to be a Transaction under the Agreement and shall be deemed to be a Transaction under an ISDA form of Master Agreement (Multicurrency-Cross Border) and Schedule substantially in the form of the Agreement but amended to reflect the name of the Assignee and the address for notices and any amended representations under Part 2 of the Agreement as may be specified in the notice of transfer.
	In circumstances in which the foregoing provisions relating to Seller’s right to transfer or assign its rights or obligations under the Transaction are not applicable, Seller may transfer any of its rights or delegate its obligations under this Transaction with the prior written consent of Buyer, which consent shall not be unreasonably withheld.
Right to Extend:	Seller may delay any Settlement Date or any other date of delivery by Seller, with respect to some or all of the Options hereunder, if Seller reasonably determines, in its discretion, that such extension is reasonably necessary to enable Seller to effect purchases of Shares in connection with its hedging activity or settlement activity hereunder in a manner that would, if Seller were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal and regulatory requirements.
Regulation:	Seller is regulated by The Securities and Futures Authority Limited.

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 Convertible Note Hedge between the Company and ML (ML as Seller), 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.
