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 (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.

(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.

(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.

(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.

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.

12

“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.

“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:

13

         Share Termination Delivery

(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

14

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 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

15

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 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

16

(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.

(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.
