  REVERSE OF SECURITY
BIOMARIN PHARMACEUTICAL INC.
 3.50% Convertible Subordinated Note due 2008
           1.
       Interest.   BioMarin Pharmaceutical Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Security at the rate per
annum shown above. The Company will pay interest semi-annually on June 15 and December 15 of each year, with the first payment to be made on December 15, 2003. Interest on the Securities will accrue on the principal amount from the most
recent date to which interest has been paid or provided for or, if no interest has been paid, from June 23, 2003. Interest will be computed on the basis of a 360-day year of twelve 30-day months.
           2.         Maturity.   The Securities will mature on June 15, 2008.
           3.        Method of Payment.   The Company will pay interest on the Securities (except defaulted interest) to the
persons who are registered Holders of Securities at the close of business on the record date set forth on the face of this Security next preceding the applicable interest payment date. Holders must surrender Securities to a Paying Agent to collect
the principal, Redemption Price or Repurchase Price of the Securities, plus, if applicable, accrued and unpaid interest, if any, payable as herein provided upon Redemption or Repurchase Upon Repurchase Event, as the case may be. The Company will pay
all amounts due with respect to the Securities in money of the United States that at the time of payment is legal tender for payment of public and private debts. If this Security is in global form, the Company will pay interest on the Securities by
wire transfer of immediately available funds to the account specified by the Holder. With respect to securities held other than in global form, the Company will make payments by wire transfer of immediately available funds to the account specified
by the Holders thereof or, at the Company’s election, by mailing a check to the Holder’s registered address.
           4.
       Paying Agent, Registrar, Conversion Agent.   Initially, Wilmington Trust Company, a Delaware banking corporation (the “Trustee”), will act as Paying Agent, Registrar and
Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice.
           5.
       Indenture.   The Company issued the Securities under an Indenture dated as of June 23, 2003 (the “Indenture”) between the Company and the Trustee. The terms of the
Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “Act”), as in effect on the date of
the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of such terms. The Securities are general unsecured subordinated obligations of the Company limited to
$125,000,000 aggregate principal amount ($150,000,000 if the Initial Purchasers (as defined in the Indenture) have elected to exercise the Initial Purchasers’ Option (as defined in the Indenture) to purchase an additional $25,000,000 of
Additional Securities), except as otherwise provided in the Indenture (except for Securities issued in substitution for destroyed, mutilated,
 5






  lost or stolen Securities). Terms used herein which are defined in the Indenture have the meanings assigned to them in the Indenture.
           6.        Optional Redemption.   The Securities will be redeemable prior to maturity at the option of the
Company, in whole or in part, at any time on or after June 20, 2006 (the date of such time, the “Redemption Date”), at the following redemption prices (expressed as percentages of the principal amount thereof), if redeemed during
the periods specified below, in each case together with accrued and unpaid interest to, but excluding, the Redemption Date:

				
	 
  	 
	 Period 
 
 	Redemption Price, as a
 percentage of the principal
 amount of Notes to be
 redeemed 
 	 
	June 20, 2006 to June 14, 2007, inclusive	 	101.40	%
	June 15, 2007 to June 14, 2008, inclusive	 	100.70	%
	 
 	 

 provided that if such Redemption Date is also an interest payment date, such accrued and unpaid interest will be payable in the ordinary course to the holder of record on the
relevant record date.
           7.        Notice of Redemption.   Notice of redemption will be mailed
at least thirty (30) days but not more than sixty (60) days before the Redemption Date to each Holder of Securities to be redeemed at its registered address. Securities in denominations larger than $1,000 principal amount may be redeemed in part but
only in integral multiples of $1,000 principal amount. On and after the Redemption Date, interest will cease to accrue on Securities or portions of them called for redemption (except to the extent the Company defaults in the payment of the
Redemption Price or accrued and unpaid interest, if any, to, but excluding, the Redemption Date).
           8.
       Repurchase at Option of Holder Upon a Repurchase Event.   In the event of a Repurchase Event, then each Holder of the Securities shall have the right, at the Holder’s option, subject to
the rights of the holders of Senior Indebtedness under Article XI of the Indenture, to require the Company to repurchase such Holder’s Securities including any portion thereof which is $1,000 in principal amount or any integral
multiple thereof on a date (the “Repurchase Date”) no later than thirty (30) days after the date on which notice of such Repurchase Event is mailed in accordance with the immediately succeeding paragraph, at a price equal to one
hundred percent (100%) of the outstanding principal amount of such Security, plus accrued and unpaid interest to, but excluding, the Repurchase Date.
           Within twenty (20) Business Days after the occurrence of the Repurchase Event, the Company is obligated to give notice of the occurrence of such Repurchase Event to
each Holder. Such notice shall include, among other things, the date by which Holder must notify the Company of such Holder’s intention to exercise the Repurchase Right and of the procedure which such Holder must follow to exercise such right.
To exercise the Repurchase Right, a Holder of Securities must, in accordance with the provisions of the Indenture, (i) deliver, no later than the close of business on the third (3rd) Business Day immediately preceding the Repurchase Date, written
notice to the Paying Agent of the Holder’s exercise of such right; and (ii) deliver, at 
 6






  any time after the delivery of such written notice, the Securities with respect to which the Holder is exercising its Repurchase Right, duly endorsed for transfer to the
Company.
          A “Repurchase Event” of the Company shall be deemed to have occurred upon the occurrence of either a “Change in
Control” or a “Termination of Trading”
          A “Change in Control” of the Company shall be deemed to have occurred at such
time as:

		
	 	            (i)      any “person” or “group” (as such terms are used for purposes of Sections 13(d)
and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as such term is used in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% or more of the total Voting Stock; or

 

		
	 	            (ii)       at any time the following persons cease for any reason to constitute a majority of the
Company’s Board of Directors:

 

		
	 	            (1)     individuals who on the Issue Date constituted the Company’s Board of Directors; and


 

		
	 	            (2)     any new directors whose election by the Company’s Board of Directors or whose nomination for
election by the Company’s stockholders was approved by at least a majority of the directors then still in office who were either directors on the Issue Date or whose election or nomination for election was previously so approved; or

 

		
	 	            (iii)      The Company consolidates with, or merges with or into, another person or any person consolidates
with, or merges with or into, the Company, in any such event other than pursuant to a transaction in which the persons that “beneficially owned,” directly or indirectly, the shares of the Company’s Voting Stock immediately prior to
such transaction, “beneficially own” immediately after such transaction, directly or indirectly, shares of the voting stock representing not less than a majority of the total voting power of all outstanding classes of voting stock of the
continuing or surviving corporation in substantially the same proportion as such ownership prior to the transaction; or

 

		
	 	            (iv)      the sale, lease, transfer or other conveyance or disposition of all or substantially all of the
assets or property of the Company to any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act, including Rule 13d-5 under the Exchange Act); or

 

		
	 	            (v)       the Company is liquidated or dissolved or the holders of the Company’s Capital Stock approve
any plan or proposal for the liquidation or dissolution of the Company;

 

		
	 	            provided, however, that a Change in Control shall not be deemed to occur if either:

 
 7







		
	 	            (A)       the Closing Sale Price of the Company’s Common Stock for each of any five (5) Trading Days
during the ten (10) Trading Days immediately preceding the Change in Control is at least equal to one hundred and five percent (105%) of the Conversion Price in effect on such Trading Day; or

 

		
	 	            (B)       in the case of a merger or consolidation, at least ninety five percent (95%) of the consideration
(excluding cash payments for fractional shares and cash payments pursuant to dissenters’ appraisal rights) in the merger or consolidation constituting the Change in Control consists of common stock traded on a U.S. national securities exchange
or quoted on The Nasdaq National Market (or which will be so traded or quoted when issued or exchanged in connection with such Change in Control) and as a result of such transaction or transactions the Securities become convertible solely into such
common stock.

 
          A “Termination of Trading” shall occur if the Common Stock of the Company (or other common stock
into which the Securities are then convertible) is neither listed for trading on a U.S. national securities exchange nor approved for trading on an established automated over-the-counter trading market in the United States.
           9.         Conversion.
         A
Holder may convert his or her Security into Common Stock of the Company at any time prior to the close of business on the earlier of (i) June 15, 2008, (ii) if the Security is called for Redemption by the Company, the Business Day immediately
preceding the Redemption Date or (iii) if the Security is to be repurchased by the Company pursuant to a Repurchase Event, the Business Day immediately preceding the Repurchase Date. The initial Conversion Rate is 71.3572 shares of Common Stock per
$1,000 principal amount of Securities, or an effective initial Conversion Price of approximately $14.01 per share, subject to adjustment in the event of certain circumstances as specified in the Indenture. The Company will deliver a check in lieu of
any fractional share. On conversion, no payment or adjustment for any unpaid and accrued interest, or liquidated damages with respect to, the Securities will be made. If a Holder surrenders a Security for conversion between the record date for the
payment of interest and prior to the next interest payment date, such Security, when surrendered for conversion, must be accompanied by payment of an amount equal to the interest thereon which the registered Holder on such record date is to receive,
unless the Securities have been called for redemption as described in the Indenture and the Redemption Date is after such record date and on or before the business day immediately following such interest payment date.
         To convert a Security, a Holder must (1) complete and sign the Conversion Notice, with appropriate signature guarantee, on the back of the Security, (2) surrender the Security
to a Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (4) pay the amount of interest, if any, the Holder may be paid as provided in the last sentence of the above
paragraph and (5) pay any transfer or similar tax if required. A Holder may convert a portion of a Security if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount.
 8






           Any shares issued upon conversion of a Security shall bear the Private Placement Legend until after the second anniversary of the
later of the Issue Date and the last date on which the Company or any Affiliate of the Company was the owner of such shares or the Security (or any predecessor security) from which such shares were converted (or such shorter period of time as
permitted by Rule 144(k) under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws in the Opinion of Counsel for the Company, unless
otherwise agreed by the Company and the Holder thereof).
           10.       Subordination.   The Securities
are subordinated in right of payment, in the manner and to the extent set forth in the Indenture, to the prior payment in full of all Senior Indebtedness. Each Holder by accepting a Security agrees to such subordination and authorizes the Trustee to
give it effect.
           11.       Denominations, Transfer, Exchange.   The Securities are in registered
form without coupons in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith. The Registrar need not exchange or register the transfer of any Security selected for redemption in whole or in part, except the unredeemed portion of Securities to be redeemed in part.
Also, it need not exchange or register the transfer of any Securities for a period of fifteen (15) days before the mailing of a notice of redemption of the Securities selected to be redeemed and in certain other circumstances provided in the
Indenture.
           12.       Persons Deemed Owners.   The registered Holder of a Security may be treated
as the owner of such Security for all purposes.
           13.       Merger or Consolidation.   The Company
shall not consolidate with, or merge with or into, or sell, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to, another person (whether in a single or series of related transactions) unless (i)
such other person is a corporation organized under the laws of the United States, any State thereof or the District of Columbia; (ii) such person assumes by supplemental indenture all the obligations of the Company, under the Securities and this
Indenture; and (iii) immediately after giving effect to the transaction, no Default or Event of Default shall exist.
           14.
      Amendments, Supplements and Waivers.   Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Subject to
certain exceptions, without notice to or the consent of any Securityholder, the Indenture or the Securities may be amended or supplemented to cure any ambiguity, defect or inconsistency, to comply with Sections 5.01, 5.02 and
10.12 of the Indenture, to make any changes or modifications to the Indenture necessary in connection with the registration of the Securities under the Securities Act
 9






  pursuant to the Registration Rights Agreement and the qualification of the Indenture under the TIA, to secure the obligations of the Company in respect of the Securities, or to add to
covenants of the Company described in the Indenture for the benefit of Securityholders, to surrender any right or power conferred upon the Company or to make provisions with respect to adjustments to the Conversion Rate as required by the Indenture
or to increase the Conversion Rate in accordance with the Indenture.
                    15.
        Defaults and Remedies.   Subject to the provisions of the Indenture, an Event of Default includes the occurrence of any of the following: (i) default in payment of principal at maturity,
upon Redemption or on a Repurchase Date with respect to a Repurchase Upon Repurchase Event or otherwise; (ii) default for thirty (30) days in payment of interest or liquidated damages; (iii) failure to timely provide a Repurchase Event Notice as
required by the provisions of this Indenture; (iv) failure by the Company for thirty (30) days after notice is given, as specified in the Indenture, to comply with any of the Company’s other agreements in the Indenture or the Securities; (v)
certain payment defaults or the acceleration of other Indebtedness, or certain payment defaults on final judgments payable in cash, of the Company and its Subsidiaries; and (vi) certain events of bankruptcy or insolvency involving the Company or its
Subsidiaries. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may declare all the Securities to be due and payable immediately, except as
provided in the Indenture. If an Event of Default specified in  Section 6.01(vii) or (viii) of the Indenture with respect to the Company occurs, the principal of and accrued interest on all the Securities shall ipso facto
become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholder. Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may
require indemnity reasonably satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the Securities then outstanding may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment) if it determines that withholding notice is in the interests of the
Securityholders. The Company must furnish an annual compliance certificate to the Trustee.
                     16.          Registration Rights.  The Holders are
entitled to registration rights as set forth in the Registration Rights Agreement (as defined in the Indenture). The Holders shall be entitled to receive liquidated damages in certain circumstances, all as set forth in the Registration Rights
Agreement.
                     17.         Trustee Dealings with
the Company.  The Trustee under the Indenture, or any banking institution serving as successor Trustee thereunder, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company
or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.
                     18.         No Recourse Against Others.  No past,
present or future director, officer, employee or stockholder, as such, of the Company shall have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation. Each Securityholder by accepting a Security waives
 10






  and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.
                     19.         Authentication.   This Security shall not
be valid until authenticated by the manual signature of the Trustee or an authenticating agent.
                     20.         Abbreviations.   Customary abbreviations
may be used in the name of a Securityholder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and
