 Ladies and Gentlemen: 

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the
above-referenced transaction entered into on the Trade Date specified below (the “Transaction”) between Morgan Stanley & Co. LLC (“Dealer”) and BioMarin Pharmaceutical Inc.
(“Counterparty”). This communication constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below.  

1. This Confirmation is subject to, and incorporates, the definitions and provisions of the 2006 ISDA Definitions (the “2006
Definitions”) and the definitions and provisions of the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”, and together with the 2006 Definitions, the “Definitions”), in each case as
published by the International Swaps and Derivatives Association, Inc. (“ISDA”). In the event of any inconsistency between the 2006 Definitions and the Equity Definitions, the Equity Definitions will govern. Certain defined terms
used herein have the meanings assigned to them in the Indenture to be dated as of October 15, 2013 between Counterparty and Wilmington Trust, National Association as trustee (the “Base Indenture”), as supplemented by a
supplemental indenture thereto to be dated as of October 15, 2013 (such supplemental indenture, the “Supplemental Indenture”, and the Base Indenture, as so supplemented, the “Indenture”) relating to the USD
340,000,000 principal amount of 1.50% senior subordinated convertible notes due 2020 and the additional USD 35,000,000 principal amount of 1.50% senior subordinated convertible notes due 2020 issued pursuant to the over-allotment option exercised on
the date hereof (the “Convertible Securities”). In the event of any inconsistency between the terms defined in the Indenture and this Confirmation, this Confirmation shall govern. For the avoidance of doubt, references herein to
sections of the Indenture are based on the draft of the Indenture most recently reviewed by the parties at the time of execution of this Confirmation. If any relevant sections of the Indenture are changed, added or renumbered following execution of
this Confirmation but prior to the execution of the Indenture, the parties will amend this Confirmation in good faith to preserve the economic intent of the parties based on the draft of the Indenture so reviewed. The parties further acknowledge
that 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
(other than as provided in Section 8(a) below) unless the parties agree otherwise in writing.  
 This Confirmation
evidences a complete and binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall be subject to an agreement (the “Agreement”) in the form of
the ISDA 2002 Master Agreement as if Dealer and Counterparty had executed an agreement in such form (without any Schedule but with the elections set forth in this Confirmation and except for the election that the “Cross Default” provisions
of Section 5(a)(vi) of the Agreement (which, for the avoidance of doubt, shall include any “Event of Default” resulting in the principal and the interest with respect to the Convertible Securities becoming immediately due and payable)
shall apply to both Dealer, with respect to which a “Threshold Amount” of 3% of the shareholders’ equity of Dealer Group as set forth on its most recent filing on Form 10-K or Form 10-Q as applicable shall be applicable, and
Counterparty, with respect to which a “Threshold Amount” of USD 15.0 million shall be applicable). For the avoidance of doubt, the Transaction shall be the only transaction under the Agreement. 







 All provisions contained in, or incorporated by reference to, the Agreement will govern this
Confirmation except as expressly modified herein. In the event of any inconsistency between this Confirmation and either the Definitions or the Agreement, this Confirmation shall govern.

avoidance


  
 3 









			
		  	of doubt, if Counterparty fails to give such notice when due in respect of any exercise of Options hereunder, Dealer’s obligation to make any payment or delivery in respect of such exercise shall be permanently extinguished,
and late notice shall not cure such failure; provided that notwithstanding the foregoing, such notice (and the related exercise of Options) shall be effective if given after the Exercise Notice Deadline, but prior to 4:00 PM New York City
time, on the fifth Exchange Business Day following the Exercise Notice Deadline, in which event the Calculation Agent shall have the right to adjust the Delivery Obligation as appropriate to reflect the additional costs (to account solely for
hedging mismatches and market losses) and expenses incurred by Dealer in connection with its hedging activities (including the unwinding of any hedge position), with such adjustments made assuming that the Dealer maintains a commercially reasonable
hedge position, as a result of Dealer not having received such notice on or prior to the Exercise Notice Deadline.
		
	 Notice of Convertible Security Settlement Method:
	  	    
Counterparty shall notify Dealer in writing before 4:00 P.M. (New York City time) on the earlier to occur of (x) the date on which it makes the irrevocable election of a settlement method and, if
applicable, the “Specified Dollar Amount” (as defined in the Indenture) in accordance with Section 9.01(g) of the Supplemental Indenture and (y) July 15, 2020 (the period from the date in this clause (y) to and including the second
“Scheduled Trading Day” immediately preceding the “Final Maturity Date” (each as defined in the Indenture), the “Free Convertibility Period”). If Counterparty fails timely to provide such notice, Counterparty
shall be deemed to have notified Dealer of combination settlement with a “Specified Dollar Amount” (as defined in the Indenture) of USD1,000 for all conversions occurring during the Free Convertibility Period. Counterparty agrees that it
shall settle any Relevant Convertible Securities with a Conversion Date occurring during the Free Convertibility Period in the same manner as provided in the Notice of Convertible Security Settlement Method it provides or is deemed to have provided

	 Delivery Obligation:
	  	In lieu of the obligations set forth in Sections 8.1 and 9.1 of the Equity Definitions, and subject to “Notice of Exercise” above and “Share Adjustments” below, in respect of an Exercise Date occurring on a
Conversion Date, Dealer will deliver to Counterparty, on the related Settlement Date, a number of Shares and/or amount of cash in USD equal to the product of (i) the Applicable Percentage and (ii) the aggregate number of Shares, if
any, that Counterparty would be obligated to deliver to the holder(s) of the Relevant Convertible Securities converted on such Conversion Date pursuant to Section 4.02(a)(iv) of the Supplemental Indenture and/or the aggregate amount of cash, if any,
in excess of USD1,000 per Convertible Security (in denominations of USD1,000) that Counterparty would be obligated to deliver to holder(s) pursuant to Section 4.02(a)(iv) of the Supplemental Indenture (except that such aggregate number of Shares
shall be determined without taking into consideration any rounding pursuant to Section 4.03 of the Supplemental Indenture and shall be rounded down to the nearest whole number) and cash in lieu of fractional Shares, if any, resulting from such
rounding, as if Counterparty had elected to satisfy its conversion obligation in respect of such Relevant Convertible Securities by the Convertible Security Settlement Method, notwithstanding any different actual election by Counterparty with
respect to the settlement of such Convertible Securities (such product, the “Convertible Obligation”); provided that (i) if the Convertible Obligation exceeds the Capped Convertible Obligation, then the Delivery Obligation
shall be the Capped Convertible Obligation; (ii) the Convertible Obligation (and, for the avoidance of doubt, the Capped Convertible Obligation) shall be determined (A) excluding any Shares and/or cash that Counterparty is obligated to deliver to
holder(s) of the Relevant Convertible Securities as a result of any adjustments to the Conversion Rate pursuant to Sections 4.01(e) or 4.13 of the Supplemental Indenture and (B) without regard to the election, if any, by Counterparty to adjust the
Conversion Rate and the related conversion obligation pursuant to Section 4.12 of the Supplemental Indenture (and, for the avoidance of doubt, the Delivery Obligation shall not include any interest payment on the Relevant Convertible Securities that
the Counterparty is (or would have been) obligated to deliver to holder(s) of the Relevant Convertible Securities for such Conversion Date); and (iii) if such exercise relates to the conversion of Relevant Convertible Securities in connection with
which holders thereof are entitled to receive additional Shares and/or cash pursuant to the adjustment to the Conversion Rate set forth in Section 4.01(e) of the Supplemental Indenture, then, notwithstanding the foregoing, the Delivery Obligation
shall include the Applicable Percentage of such additional Shares and/or cash, except that the Delivery Obligation shall be capped so that the value of the Delivery Obligation per Option (with the value of any Shares included in the Delivery
Obligation determined by the Calculation Agent using the VWAP Price on the last day of the relevant “Observation Period”) does not exceed the amount as determined by the Calculation Agent that would be payable by Dealer pursuant to Section
6 of the Agreement if such Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect


  
 5 









			
		  	to which the Transaction (except that, for purposes of determining such amount (x) the Number of Options shall be deemed to be equal to the number of Options exercised on such Exercise Date and (y) such amount payable will be
determined as if Section 4.01(e) of the Supplemental Indenture were deleted) was the sole Affected Transaction and Counterparty was the sole Affected Party (determined without regard to Section 8(b) of this Confirmation), it being understood that
the cap described in this clause (iii) is in addition to, and cumulative with, clauses (i) and (ii) of this proviso. Notwithstanding the foregoing, and in addition to the caps described in clauses (i), (ii) and (iii) of the proviso above, in all
events the Delivery Obligation shall be capped so that the value of the Delivery Obligation does not exceed the value of the ratio the numerator of which is the Convertible Obligation (with the Convertible Obligation determined based on the actual
settlement method elected by Counterparty with respect to such Relevant Convertible Securities instead of the Convertible Security Settlement Method and with the value of any Shares included in either the Delivery Obligation or such Convertible
Obligation determined by the Calculation Agent using the VWAP Price on the last day of the relevant “Observation Period” (as defined in the Indenture and as modified by the provision set forth opposite the caption “Convertible
Security Settlement Method”)) and the denominator of which is the aggregate of all Applicable Percentages under all outstanding Capped Call Transactions in respect of Convertible Securities as of the time of such calculation.
		
	 Capped Convertible Obligation:
	  	In respect of an Exercise Date occurring on a Conversion Date, the Convertible Obligation that would apply if the “Daily VWAP” for each “Trading Day” in the “Observation Period” (each as defined in
the Indenture) or, if applicable, the assumed “Observation Period” specified in clause (ii) of “Convertible Security Settlement Method” below, were the lesser of (x) the Cap Price and (y) the actual Daily VWAP for such Trading
Day as defined in the Indenture.
		
	 Convertible Security Settlement Method:
	  	For any Relevant Convertible Securities, if Counterparty has notified Dealer in the related Notice of Exercise (or in the Notice of Convertible Security Settlement Method, as the case may be) that it has elected to satisfy its
conversion obligation in respect of such Relevant Convertible Securities in cash or in a combination of cash and Shares in accordance with Section 4.02(a) of the Supplemental Indenture (a “Cash Election”) with a “Specified
Dollar Amount” (as defined in the Indenture) of at least USD1,000, the Convertible Security Settlement Method shall be the settlement method actually so elected by Counterparty in respect of such Relevant Convertible Securities; otherwise, the
Convertible Security Settlement Method shall (i) assume Counterparty made a Cash Election with respect to such Relevant Convertible Securities with a “Specified Dollar Amount” (as defined in the Indenture) of USD1,000 per Relevant
Convertible Security and (ii) be calculated as if the relevant “Observation Period” (as defined in the Indenture) pursuant to Section 4.02(a)(iv) of the Supplemental Indenture consisted of 50 “Trading Days” (as defined in the
Indenture) commencing on (x) the third “Scheduled Trading Day” (as defined in the Indenture) after the Conversion Date for


  
 6 









			
		  	conversions occurring prior to the Free Convertibility Period or (y) the 52nd “Scheduled Trading Day” prior to the “Final Maturity Date” (each as defined in the Indenture) for conversion occurring during the
Free Convertibility Period.
		
	 Notice of Delivery Obligation:
	  	No later than the Exchange Business Day immediately following the last day of the relevant “Observation Period” (as defined in the Indenture and as modified by the provision set forth opposite the caption
“Convertible Security Settlement Method”), Counterparty shall give Dealer notice of the aggregate number of Shares and/or cash comprising the Convertible Obligations for all Relevant Convertible Securities (it being understood, for the
avoidance of doubt, that the requirement of Counterparty to deliver such notice shall not limit Counterparty’s obligations with respect to Notice of Exercise or Notice of Convertible Security Settlement Method or Dealer’s obligations with
respect to Delivery Obligation, each as set forth above, in any way).
		
	 Other Applicable Provisions:
	  	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.1(c), 9.8, 9.9, 9.10 and 9.11 (except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be
modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Counterparty is the Issuer of the Shares) of the Equity
Definitions will be applicable as if “Physical Settlement” applied to the Transaction.
		
	 Restricted Certificated Shares:
	  	Notwithstanding anything to the contrary in the Equity Definitions, Dealer may, in whole or in part, deliver Shares required to be delivered to Counterparty hereunder in certificated form in lieu of delivery through the Clearance
System. With respect to such certificated Shares, the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by deleting the remainder of the provision after the word “encumbrance” in the fourth
line thereof.
		
	Share Adjustments:	  	
		
	 Method of Adjustment:
	  	Notwithstanding Section 11.2 of the Equity Definitions, upon the occurrence of any event or condition set forth in Section 4.06 of the Supplemental Indenture that results in an adjustment under the Indenture, the Calculation
Agent shall make a corresponding adjustment to the terms relevant to the exercise, settlement or payment of the Transaction and may adjust the Cap Price as appropriate to account for the economic effect on the Transaction of such event or condition;
provided that the Cap Price shall not be adjusted so that it is less than the Strike Price. Immediately upon the occurrence of any such event or condition contemplated by Section 4.06 of the Supplemental Indenture, Counterparty shall notify
the Calculation Agent of such event or condition; and once the adjustments to be made to the terms of the Indenture and the Convertible Securities in respect of such event or condition have been determined, Counterparty shall immediately notify the
Calculation Agent in writing of the details of such adjustments.


  
 7

	  	Notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in Section 7.01 of the Supplemental Indenture.
		
	 Consequences of Merger Events and Tender Offer:
	  	    
Notwithstanding Sections 12.2 and 12.3 of the Equity Definitions, (i) upon the occurrence of a Merger Event that results in an adjustment under the Indenture, the Calculation Agent shall make a
corresponding adjustment to the terms relevant to the exercise, settlement or payment of the Transaction; provided that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to Sections 4.01(e) 4.13 of
the Supplemental Indenture and the election, if any, by Counterparty to adjust the Conversion Rate and the related conversion obligation pursuant to Section 4.12 of the Supplemental Indenture; and provided further that the Calculation Agent
may limit or alter any such adjustment referenced in this clause (i) so that the fair value of the Transaction to Dealer (taking into account a commercially reasonable hedge position) is not adversely affected as a result of such adjustment); and
provided further that if, with respect to a Merger Event, (x) the consideration for the Shares includes (or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation organized under the laws of
the United States, any State thereof or the District of Columbia or (y) the Counterparty following such Merger Event will not be a corporation organized under the laws of the United States, any State thereof or the District of Columbia or will not
be the Issuer following such Merger Event, Cancellation and Payment (Calculation Agent Determination) shall apply; and (ii) in such event, the Calculation Agent may adjust the Cap Price as appropriate to account for the economic effect on the
Transaction of such event; provided that the Cap Price shall not be adjusted so that it is less than the Strike Price.
		
	 Notice of Merger Consideration:
	  	Upon the occurrence of a Merger Event that causes the Shares to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), Counterparty shall
reasonably promptly (but, in any event prior to the effective time of such Merger Event) notify the Calculation Agent of (i) the weighted average of the types and amounts of consideration received by the holders of Shares entitled to receive cash,
securities or other property or assets with respect to or in exchange for such Shares in any Merger Event who affirmatively make such an election and (ii) the details of the adjustment made under the Indenture in respect of such Merger
Event.
		
	 Nationalization, Insolvency or Delisting:
	  	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it shall also constitute a Delisting if the Shares are not
immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any

 7. Representations, Warranties and Agreements: 

(a) In addition to the representations and warranties in the Agreement and those contained elsewhere herein, Counterparty
represents and warrants to and for the benefit of, and agrees with, Dealer as follows: 
 (i) On the Trade Date, and as of
the date of any election by Counterparty of the Share Termination Alternative under (and as defined in) Section 8(b) below, (A) none of Counterparty and its officers and directors is aware of any material nonpublic information regarding
Counterparty or the Shares and (B) all reports and other documents filed by Counterparty with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) when
considered as a whole (with the more recent such reports and documents deemed to amend inconsistent statements contained in any earlier such reports and documents), do not contain any untrue statement of a material fact or any omission of a material
fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading. 

(ii) On the Trade Date and on each day during the Observation Period (or, if applicable, the assumed “Observation
Period” specified in clause (ii) of “Convertible Security Settlement Method” above) applicable to the Relevant Convertible Securities and any Early Termination Period, neither Counterparty nor any “affiliated purchaser”
(each as defined in Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by means of any cash-settled or other derivative instrument) purchase, offer to purchase,
place any bid or limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an equivalent interest, including a unit of beneficial interest in a trust or limited partnership or a depository share) or any
security convertible into or exchangeable or exercisable for Shares, except through Dealer. 
 (iii) Without limiting the
generality of Section 13.1 of the Equity Definitions, Counterparty acknowledges that Dealer is not making any representations or warranties or taking any position or expressing any view with respect to the treatment of the Transaction under any
accounting standards including ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, or ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in
Entity’s Own Equity (or any successor issue statements) or under FASB’s Liabilities & Equity Project. 

(iv) Without limiting the generality of Section 3(a)(iii) of the Agreement, to Counterparty’s knowledge, the
Transaction will not violate Rule 13e-1 or Rule 13e-4 under the Exchange Act. 
 (v) Prior to the Trade Date, Counterparty
shall deliver to Dealer a resolution of Counterparty’s board of directors authorizing the Transaction and such other certificate or certificates as Dealer shall reasonably request. 

(vi) Counterparty is not entering into this Confirmation 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) or otherwise in violation of the Exchange Act. 

(vii) Counterparty is not, and after giving effect to the transactions contemplated hereby will not be, required to register
as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended. 

  
 11 








 (viii) On each of the Trade Date and the Premium Payment Date,
Counterparty is not, or will not be, “insolvent” (as such term is defined under Section 101(32) of the U.S. Bankruptcy Code (Title 11 of the United States Code) (the “Bankruptcy Code”)) and Counterparty would be able
to purchase the Shares hereunder in compliance with the laws of the jurisdiction of its incorporation. 
 (ix) No
law, rule, regulation or regulatory order of (x) any state or local jurisdiction (including non-U.S. jurisdictions) applicable to the Shares as a result of Counterparty’s particular industry or (y) any material jurisdiction (including
non-U.S. jurisdictions) applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of Dealer or
its affiliates owning or holding (however defined) Shares. 
 (x) Counterparty understands no obligations of Dealer to it
hereunder will be entitled to the benefit of deposit insurance and that such obligations will not be guaranteed by any affiliate of Dealer or any governmental agency. 

(b) Each of Dealer and Counterparty agrees and represents that it is an “eligible contract participant” as defined in
the U.S. Commodity Exchange Act, as amended. 
 (c) Each of Dealer and Counterparty acknowledges that the offer and
sale of the Transaction to it is intended to be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”), by virtue of Section 4(2) thereof. Accordingly, Counterparty represents and warrants
to Dealer 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, (iii) it is entering into the Transaction for its own account and without a view to the distribution or resale thereof, and (iv) the assignment, transfer or other disposition of the
Transaction has not been and will not be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state securities laws. 

(d) Counterparty acknowledges that during (x) the Observation Period (or, if applicable, the assumed
“Observation Period” specified in clause (ii) of “Convertible Security Settlement Method” above) applicable to the Relevant Convertible Securities and (y) in the event an Early Termination Date is designated due to an
Additional Termination Event as a result of an Excluded Conversion Event, a period starting on or about such Early Termination Date as reasonably determined by Dealer and notified to Counterparty (an “Early Termination Period”), the
Shares or securities that are convertible into, or exchangeable or exercisable for, Shares will not be subject to a “restricted period,” as such term is defined in Regulation M under the Exchange Act (“Regulation M”)
due to the actions of Counterparty. Dealer acknowledges that it intends to hedge its obligations with respect to the Transaction on the Trade Date by entering into cash-settled total return swaps on the Shares.  

(e) Dealer represents that it is a “financial institution,” “swap participant” and “financial
participant” within the meaning of Sections 101(22), 101(53C) and 101(22A) of the Bankruptcy Code. The parties hereto further agree and acknowledge that it is the intent of the parties that (A) this Confirmation is (i) a
“securities contract,” as such term is defined in Section 741(7) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment
amount” or “other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “settlement payment,” within the meaning of Section 546 of the Bankruptcy Code and (ii) a “swap
agreement,” as such term is defined in Section 101(53B) of the Bankruptcy Code, with respect to which each payment and delivery hereunder or in connection herewith is a “termination value,” “payment amount” or
“other transfer obligation” within the meaning of Section 362 of the Bankruptcy Code and a “transfer,” as such term is defined in Section 101(54) of the Bankruptcy Code and a “payment or other transfer of
property” within the meaning of Sections 362 and 546 of the Bankruptcy Code, and (B) Dealer is entitled to the protections afforded by, among other sections, Sections 362(b)(6), 362(b)(17), 362(o), 546(e), 546(g), 548(d)(2), 555, 560 and
561 of the Bankruptcy Code. 

  
 12 








 (f) Counterparty represents that it (i) is capable of evaluating investment
risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities; (ii) will exercise independent judgment in evaluating the recommendations of any broker-dealer or its
associated persons, unless it has otherwise notified the broker-dealer in writing; and (iii) has total assets of at least USD 50.0 million. 

(g) Counterparty understands that notwithstanding any other relationship between Counterparty and Dealer and its affiliates, in
connection with this Transaction and any other over-the-counter derivative transactions between Counterparty and Dealer or its affiliates, Dealer or its affiliates is acting as principal and is not a fiduciary or advisor in respect of any such
transaction, including any entry, exercise, amendment, unwind or termination thereof. 
 (h) Counterparty represents
and warrants that it has received, read and understands the OTC Options Risk Disclosure Statement and a copy of the most recent disclosure pamphlet prepared by The Options Clearing Corporation entitled “Characteristics and Risks of
Standardized Options”. 
 (i) Each party acknowledges and agrees to be bound by the Conduct Rules of the
Financial Industry Regulatory Authority, Inc. applicable to transactions in options, and further agrees not to violate the position and exercise limits set forth therein. 

(j) Counterparty shall deliver to Dealer an opinion of counsel, dated as of the Effective Date and reasonably acceptable to
Dealer in form and substance, with respect to the matters set forth in Section 3(a) of the Agreement. 
 8. Other Provisions:

 (a) Additional Termination Events. The occurrence of (i) an Amendment Event or (ii) an Excluded
Conversion Event shall be an Additional Termination Event with respect to which the Transaction is the sole Affected Transaction and Counterparty is the sole Affected Party, Dealer shall be the party entitled to designate an Early Termination Date
pursuant to Section 6(b) of the Agreement and Dealer shall so designate an Early Termination Date; provided that in the case of an Excluded Conversion Event the Transaction shall be subject to termination only in respect of a number of
Options equal to the number of Convertible Securities that cease to be outstanding in connection with or as a result of such Excluded Conversion Event. For the avoidance of doubt, in determining the amount payable in respect of such Affected
Transaction pursuant to Section 6 of the Agreement in connection with an Excluded Conversion Event, the Calculation Agent shall assume that (x) the relevant Excluded Convertible Securities shall not have been converted and remain
outstanding, and (y) in the case of an Induced Conversion, any adjustments, agreements, additional payments, deliveries or acquisitions by or on behalf of Counterparty or any affiliate of Counterparty in connection therewith had not occurred.
 
 Counterparty shall, within one Scheduled Trading Day of the “Conversion Date” (as defined in the
Indenture) for any Excluded Conversion Event, provide Dealer with written notice of (i) such number of Excluded Convertible Securities, (ii) the scheduled settlement under the Indenture for the Excluded Convertible Securities converted on
such Conversion Date, (iii) whether such Excluded Convertible Securities will be settled by Counterparty by delivery of cash, Shares or a combination of cash and Shares and, if such a combination, the “Specified Dollar Amount” (as
defined in the Indenture) and (iv) the first “Scheduled Trading Day” of the “Observation Period” (as defined in the Indenture). Counterparty acknowledges its responsibilities under applicable securities laws, and in
particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, in respect of any election of a settlement method with respect to the Excluded Convertible Securities. 

“Amendment Event” means that Counterparty amends, modifies, supplements, waives or obtains a waiver
that is material in nature, whether considered individually or in the aggregate, in respect of any term of the Indenture or the Convertible Securities governing the principal amount, coupon, maturity, repurchase obligation of Counterparty,
redemption right of Counterparty, any term relating to conversion of the Convertible Securities (including changes to the conversion price, conversion settlement dates or conversion conditions), or any term that would require consent of the holders
of not less than 100% of the principal amount of the Convertible Securities to amend, in each case without the consent of Dealer. 

  
 13 








 “Excluded Conversion Event” means any conversion of any Excluded
Convertible Securities. 
 “Induced Conversion” means a conversion of any Excluded Convertible Securities
(A) in connection with (x) an adjustment to the Conversion Rate effected by Counterparty (whether pursuant to Section 4.12 of the Supplemental Indenture or otherwise) that is not required under the terms of the Indenture or
(y) an agreement by Counterparty with the holder(s) of such Convertible Securities whereby, in the case of either (x) or (y), the holder(s) of such Convertible Securities receive upon conversion or pursuant to such agreement, as the case
may be, a payment of cash or delivery of Shares or any other property or item of value that was not required under the terms of the Indenture or (B) after having been acquired from a holder of Convertible Securities by or on behalf of
Counterparty or any of its affiliates other than pursuant to a conversion by such Holder and thereafter converted by or on behalf of Counterparty or any affiliate of Counterparty. 

In no event shall the Close-out Amount paid to Counterparty in connection with an Additional Termination Event occurring as a
result of an Excluded Conversion Event exceed an amount (if positive) equal to the product of (i) (a) the amount of cash paid and the number of Shares issued by Counterparty under the Indenture upon conversion of the Excluded Convertible
Securities, less (b) the principal amount of the Excluded Convertible Securities so converted, and (ii) the ratio the numerator of which is the Applicable Percentage and the denominator of which is the aggregate of all Applicable
Percentages under all outstanding Capped Call Transactions in respect of Convertible Securities as of the time of such Excluded Conversion Event. 

(b) Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events. If Dealer
shall owe Counterparty any amount pursuant to “Consequences of Merger Events and Tender Offers” above or Sections 12.6, 12.7 or 12.9 of the Equity Definitions or pursuant to Section 6(d)(ii) of the Agreement (a
“Payment Obligation”), Counterparty shall have the right, in its sole discretion, to require Dealer to satisfy any such Payment Obligation by the Share Termination Alternative (as defined below) by giving irrevocable
telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 9:30 A.M. New York City time on the relevant merger date, Announcement Date, Early Termination Date or date of cancellation or termination in respect
of an Extraordinary Event, as applicable (“Notice of Share Termination”); provided that if Counterparty does not elect to require Dealer to satisfy its Payment Obligation by the Share Termination Alternative,
Dealer shall have the right, in its sole discretion, to elect to satisfy its Payment Obligation by the Share Termination Alternative, notwithstanding Counterparty’s failure to elect or election to the contrary; and provided further that
Counterparty shall not have the right to so elect (but, for the avoidance of doubt, Dealer shall have the right to so elect) in the event of (i) an Insolvency, a Nationalization or a Merger Event, in each case, in which the consideration or
proceeds to be paid to holders of Shares consists solely of cash or (ii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party, which Event of Default or Termination
Event resulted from an event or events within Counterparty’s control. Upon such Notice of Share Termination, the following provisions shall apply on the Scheduled Trading Day immediately following the relevant merger date, Announcement Date,
Early Termination Date or date of cancellation or termination in respect of an Extraordinary Event, as applicable: 
  

			
	Share Termination Alternative:	  	Applicable and means that Dealer shall deliver to Counterparty the Share Termination Delivery Property on the date on which the Payment Obligation would otherwise be due pursuant to “Consequences of Merger Events and Tender
Offers” above, Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, or such later date as the Calculation Agent may reasonably determine (the “Share Termination Payment
Date”), in satisfaction of the Payment Obligation.
		
	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 the aggregate amount 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.



  
 14 









			
	Share Termination Unit Price:	  	The value of property contained in one Share Termination Delivery Unit on the date such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation Agent in its
discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation.
		
	Share Termination Delivery Unit:	  	In the case of a Termination Event, Event of Default, Delisting or Additional Disruption Event, one Share or, in the case of an Insolvency, Nationalization or Merger Event, one Share or 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 Insolvency, Nationalization or Merger Event, as
applicable. If such Insolvency, Nationalization or Merger Event involves a choice of consideration to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of cash.
		
	Failure to Deliver:	  	Applicable
		
	Other applicable provisions:	  	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.10 and 9.11 (except that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by excluding
any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws arising as a result of the fact that Counterparty is the issuer of the Shares or any portion of the Share Termination
Delivery Units) of the Equity Definitions will be applicable as if “Physical Settlement” applied to the Transaction, except that all references to “Shares” shall be read as references to “Share Termination Delivery
Units.”


 (c) Disposition of Hedge Shares. Counterparty hereby agrees that if, in the good
faith reasonable judgment of Dealer based on advice of outside counsel, any Shares (the “Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction (other than any Hedge Shares that were
“restricted securities” as defined in Rule 144(a) of the Securities Act) cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at its election: (i) in order to allow
Dealer to sell the Hedge Shares in a registered offering, make available to Dealer 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
reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered secondary offering of similar size of an issuer of similar size and (B) afford Dealer a reasonable opportunity to conduct a “due
diligence” investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities; provided, however, that if Dealer, 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 Section 8(c) shall apply at the election of
Counterparty; (ii) in order to allow Dealer 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 of similar size of an issuer of similar size, in form and substance commercially reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its
commercially reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement; for the avoidance of doubt, any such adjustment will be solely based on
the variables permitted under ASC 815-40); or (iii) purchase the Hedge Shares from Dealer at the VWAP Price on such Exchange Business Days, and in the amounts, requested by Dealer. “VWAP Price” means, on any Exchange Business
Day, the per Share volume-weighted average price as displayed under the 

  
 15 








 
heading “Bloomberg VWAP” on Bloomberg page “BMRN <equity> VAP” (or any successor thereto) in respect of the period from 9:30 a.m. to 4:00 p.m. (New York City time) on
such Exchange Business Day (or if such volume-weighted average price is unavailable or is manifestly incorrect, the market value of one Share on such Exchange Business Day, as determined by the Calculation Agent using a volume-weighted method). 

(d) Amendment to Equity Definitions. The following amendment shall be made to the Equity Definitions: 

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 Dealer’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.” 

(e) Repurchase and Conversion Rate Adjustment Notices. Counterparty shall, simultaneously with, or
immediately after, effecting any repurchase of Shares or 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), give Dealer a written notice of such repurchase or Conversion Rate Adjustment Event (a “Repurchase Notice”) if, following such repurchase or Conversion Rate Adjustment Event, the Notice
Percentage as determined on the date of such Repurchase Notice is (i) greater than 4.5% 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), and, if such repurchase or Conversion Rate Adjustment Event, or the intention to effect the same, would constitute material non-public information with respect to
Counterparty or the Shares, Counterparty shall make public disclosure thereof at or prior to delivery of such Repurchase Notice. The “Notice Percentage” as of any day is the fraction, expressed as a percentage, the numerator of
which is the Number of Shares and the denominator of which is the number of Shares outstanding on such day. In the event that Counterparty fails to provide Dealer with a Repurchase Notice on the day and in the manner specified in this
Section 8(e) then Counterparty agrees to indemnify and hold harmless Dealer, its affiliates and their respective directors, officers, employees, agents and controlling persons (Dealer 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 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 Dealer. 

(f) Transfer and Assignment. Either party may transfer any of its rights or obligations under the Transaction with the
prior written consent of the non-transferring party, such consent not to be unreasonably withheld or delayed. Counterparty may transfer or assign any of its rights or obligations under the Transaction with the prior written consent of Dealer, such
consent not to be unreasonably withheld or delayed, in connection with a transaction where the rights or obligations of the Counterparty under the Indenture are being transferred or assigned under the terms of the Indenture; provided Dealer
may condition its consent on any of the following, without limitation: (i) the receipt by Dealer of opinions and documents reasonably satisfactory to Dealer in connection with such assignment, (ii) such assignment being effected on terms
reasonably satisfactory to Dealer with respect to any legal and regulatory requirements relevant to Dealer, and (iii) Counterparty continuing to be obligated to provide notices hereunder relating to the Convertible Securities and continuing to


  
 16 








 
be obligated with respect to “Disposition of Hedge Shares” and “Repurchase Notices” above. In addition, Dealer may transfer or assign without any consent of the Counterparty
its rights and obligations hereunder and under the Agreement, in whole or in part, to any of its affiliates if such affiliate or its guarantor has a long-term rating equal to or higher than Dealer as rated by either Moody’s or
Standard & Poor’s. Any such assignment shall be fully effective upon notice to Counterparty of such assignment, together with notice of such affiliate’s agreement to perform the Transaction and be bound by its terms in every way
as if the affiliate had been an original party to the Transaction in place with Dealer and Dealer shall be released from its obligations hereunder. At any time at which any Excess Ownership Position or a Hedging Disruption exists, if Dealer, in its
discretion, is unable to effect a transfer or assignment to an affiliate in accordance with the requirements set forth above after using its commercially reasonable efforts on pricing terms and within a time period reasonably acceptable to Dealer
such that an Excess Ownership Position or a Hedging Disruption, as the case may be, no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”)
of the Transaction, such that such Excess Ownership Position or Hedging Disruption, as the case may be, no longer exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment or
delivery shall be made pursuant to Section 6 of the Agreement and Section 8(b) of this Confirmation as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion
of the Transaction, (ii) Counterparty shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction shall be the only Terminated Transaction. “Excess Ownership
Position” means any of the following: (i) the Equity Percentage exceeds 9.0%, (ii) Dealer or any “affiliate” or “associate” of Dealer would own in excess of 14% of the outstanding Shares for purposes of
Section 203 of the Delaware General Corporation Law or (iii) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a
“Dealer Person”) under any federal, state or local laws, regulations, regulatory orders or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“Applicable
Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number of Shares equal to (x) the number of Shares that would give
rise to reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under Applicable Restrictions, as
determined by Dealer in its reasonable discretion, and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of
Counterparty or any contract or agreement to which Counterparty is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination. The “Equity Percentage” as of any day is the
fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject to aggregation with Dealer, for purposes of the “beneficial ownership” test
under Section 13 of the Exchange Act, or any “group” (within the meaning of Section 13) of which Dealer is or may be deemed to be a part (Dealer and any such affiliates, persons and groups, collectively, “Dealer
Group”) beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the
equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such number) and (B) the denominator of which is the number of Shares outstanding on such day. 

(g) Staggered Settlement. If based upon advice of counsel based on applicable legal requirements, Dealer reasonably and
in good faith determines that it would not be advisable to settle the Transaction on a single Settlement Date, Dealer 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”) or at two or more times on the Nominal Settlement Date as follows: 

(i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or
prior to such Nominal Settlement Date, but not prior to the beginning of the related “Observation Period” (as defined in the Indenture)) or delivery times and how it will allocate the Shares it is required to deliver under “Delivery
Obligation” (above) among the Staggered Settlement Dates or delivery times; and 
 (ii) the aggregate number of Shares
that Dealer will deliver to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date. 

  
 17 








 (h) Right to Extend. Dealer may postpone any Exercise Date or Settlement
Date or any other date of valuation or delivery by Dealer, with respect to some or all of the relevant Options (in which event the Calculation Agent shall make appropriate adjustments to the Delivery Obligation), if Dealer in good faith determines,
in its commercially reasonable discretion and based on advice of counsel in the case of the immediately following clause (ii), that such extension is reasonably necessary or appropriate to (i) preserve Dealer’s hedging or hedge unwind
activity hereunder in light of existing liquidity conditions in the cash market, the stock loan market or any other relevant market or (ii) to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or
settlement activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures
applicable to Dealer. 
 (i) Adjustments. For the avoidance of doubt, whenever the Calculation Agent is called
upon to make an adjustment pursuant to the terms of this Confirmation or the Definitions to take into account the effect of an event, the Calculation Agent shall make such adjustment by reference to the effect of such event on the Hedging Party,
assuming that the Hedging Party maintains a commercially reasonable hedge position. 
 (j) 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. 

(k) Designation by Dealer. Notwithstanding any other provision in this Confirmation to the contrary requiring or
allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such shares or other securities and otherwise to perform
Dealer obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance. 

(l) No Netting and Set-off. Each party waives any and all rights it may have to set off obligations arising under
the Agreement and the Transaction against other obligations between the parties, whether arising under any other agreement, applicable law or otherwise. 

(m) Equity Rights. Dealer acknowledges and agrees that this Confirmation is not intended to convey to it rights
with respect to the Transaction that are senior to the claims of common stockholders in the event of Counterparty’s bankruptcy. For the avoidance of doubt, the parties agree that the preceding sentence shall not apply at any time other than
during Counterparty’s bankruptcy to any claim arising as a result of a breach by Counterparty of any of its obligations under this Confirmation or the Agreement. For the avoidance of doubt, the parties acknowledge that this Confirmation is not
secured by any collateral that would otherwise secure the obligations of Counterparty herein under or pursuant to any other agreement. 

(n) Early Unwind. In the event the sale by Counterparty of the Optional Securities is not
consummated with the initial purchasers pursuant to the Underwriting Agreement dated as of October 8, 2013, between the Counterparty and Merrill Lynch, Pierce, Fenner & Smith Incorporated as representative of the Underwriters party
thereto (the “Underwriting Agreement”) for any reason other than due to Dealer’s fault by the close of business in New York on October 15, 2013 (or such later date as agreed upon by the parties, which in no event shall be
later than October 23, 2013) (October 15, 2013 or such later date being the “Early Unwind Date”), the 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 Dealer and Counterparty thereunder shall be cancelled and terminated and (ii) Counterparty shall reimburse Dealer for the aggregate amount of costs and


  
 18 








 
expenses actually incurred in connection with the unwinding of Dealer’s hedging activities in respect of the Transaction (including market losses incurred in reselling any Shares
purchased by Dealer or its affiliates in connection with such hedging activities). At the election of Counterparty, in lieu of such payment Counterparty may deliver to Dealer, on such Early Unwind Date, Shares with a value equal to such amount, as
determined by the Calculation Agent, in which event the parties shall enter into customary and commercially reasonable documentation relating to the registered or exempt resale of such Shares; provided that in no event shall
Counterparty be obligated to so deliver a number of Shares in excess of two multiplied by the Number Shares. Following such termination, cancellation and payment, 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 either party arising out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date. Dealer
and Counterparty represent and acknowledge to the other that upon an Early Unwind and following the payment referred to above, all obligations with respect to the Transaction shall be deemed fully and finally discharged.
