Ladies and Gentlemen:

BioMarin Pharmaceutical Inc., a Delaware corporation (the “Company”), confirms its agreement (this “Agreement”) with Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated (“Xxxxxxx Xxxxx” or an “Underwriter”), Barclays Capital Inc. (“Barclays” or an “Underwriter”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Xxxxxxx Xxxxx and Barclays are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective number of shares of Common Stock, par value $0.001 per share, of the Company (“Common Stock”) set forth in Schedule A hereto and (ii) the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 650,000 additional shares of Common Stock. The aforesaid 6,500,000 shares of Common Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 650,000 shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (File No. 333-181766), including the related preliminary prospectus or prospectuses, which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “Rules and Regulations”) under the Securities Act of 1933, as amended (the “Act”). Such registration statement covers the registration of the Securities under the Act. Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430B (“Rule 430B”) of the Rules and Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the Rules and Regulations. Any information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Each preliminary prospectus used in connection with the offering of the Securities that omitted Rule 430B Information, is herein called a “Preliminary Prospectus” and all references herein to any “Preliminary Prospectus” shall be deemed to include the Statutory Prospectus (as hereinafter defined). Such registration statement, at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act at such time and the documents otherwise deemed to be a part thereof or included therein by the Rules and Regulations, is herein called the “Registration Statement”; provided, however, that the “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of such registration statement with respect to the Securities within the meaning of paragraph (f)(2) of Rule 430B, including the exhibits and schedules thereto as of such time, the documents incorporated or deemed incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B. The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The final prospectus in the form first furnished or made available to the Underwriter for use in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act at the time of the execution of this Agreement is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any Preliminary Prospectus, the Statutory Prospectus, the Prospectus or any Issuer Free Writing Prospectus (as hereinafter defined) or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any Preliminary Prospectus, the Statutory Prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by the Rules and

Regulations to be a part of or included in the Registration Statement, any Preliminary Prospectus, the Statutory Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any Preliminary Prospectus, the Statutory Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is incorporated by reference in or otherwise deemed by the Rules and Regulations to be a part of or included in the Registration Statement, any Preliminary Prospectus, the Statutory Prospectus or the Prospectus, as the case may be.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof, the Applicable Time referred to in Section 1(a)(ii) hereof and as of the Closing Time referred to in Section 2(c) hereof, and as of each Date of Delivery (if any) referred to in Section 2(b) hereof, and agrees with each Underwriter, as follows:

(i) Status as a Well-Known Seasoned Issuer. (A) At the time of filing the initial Registration Statement, (B) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Rules and Regulations (“Rule 163(c)”)) made any offer relating to the Securities in reliance on the exemption of Rule 163 of the Rules and Regulations (“Rule 163”) and (D) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405 of the Rules and Regulations (“Rule 405”), including not having been and not being an “ineligible issuer” as defined in Rule 405. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on a Rule 405 “automatic shelf registration statement”. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) of the Rules and Regulations objecting to the use of the automatic shelf registration statement form.

At the time of filing the Original Registration Statement, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Rules and Regulations) of the Securities and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405, without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an “ineligible issuer.”

(ii) Registration Statement, Prospectus and Disclosure at Time of Sale. The Original Registration Statement became effective upon filing under Rule 462(e) of the Rules and Regulations (“Rule 462(e)”) on May 30, 2012, and any post-effective amendment thereto also became effective upon filing under Rule 462(e). No stop order preventing or suspending the use of any Preliminary Prospectus, the Prospectus or suspending the effectiveness of the Registration Statement has been issued under the Act

and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request received by the Company on the part of the Commission for additional information has been complied with.

Any offer that is a written communication relating to the Securities made prior to the filing of the Original Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c)) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Act provided by Rule 163.

At the respective times the Original Registration Statement and each amendment thereto became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the Rules and Regulations, at the Applicable Time and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery), the Registration Statement complied and will comply in all material respects with the requirements of the Act and the Rules and Regulations, and the Exchange Act and the rules and regulations of the Commission thereunder (the “Exchange Act Regulations”), and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

Neither the Prospectus nor any amendment thereof or supplements thereto, at the time the Prospectus or any such amendment or supplement was issued and at the Closing Time (and, if any Option Securities are purchased, at the Date of Delivery) included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Each Preliminary Prospectus (including the prospectus or prospectuses filed as part of the Original Registration Statement or any amendment thereto) and the Prospectus complied when so filed in all material respects with the Rules and Regulations and each Preliminary Prospectus and the Prospectus delivered to the Underwriter for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

As of the Applicable Time (as defined below), neither (x) the Issuer General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time and the Statutory Prospectus (as defined below), all considered together with the other information set forth on Schedule B (collectively, the “General Disclosure Package”), nor (y) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

As used in this subsection and elsewhere in this Agreement:

“Issuer General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors (other than a Bona Fide Electronic Road Show, as defined in Rule 433), as evidenced by its being specified in Schedule B hereto.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that the issuer notified or notifies the Representatives as described in Section 3(e) hereof, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference therein and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified. Any offer that is a written communication relating to the Securities made prior to the initial filing of the Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c)) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Act provided by Rule 163.

Prospectus, any Preliminary Prospectus or any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company by the Representatives on behalf of any Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Representatives consists of the information described as such in Section 6(b) hereof.

(iii) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the Act and the Rules and Regulations and the Exchange Act and the Exchange Act Regulations, and, when read together with the other information (a) in the Prospectus at the time the Registration Statement became effective (including each deemed effective date with respect to the Underwriters pursuant to Rule 430(B)(f)(2) of the Rules and Regulations), (b) in the Preliminary Prospectus at the earlier of the time the Preliminary Prospectus was first used and the date and time of the first contract of sale of Securities in this offering, (c) in the Prospectus at the Closing Time (and if any Option Securities are purchased, at the Date of Delivery), did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

No labor dispute with the employees of the Company or any subsidiary exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any of its subsidiaries’ principal suppliers, manufacturers, customers or contractors, which, in either case, would result in a Material Adverse Effect.

(xiv) Absence of Proceedings. There is no claim, action, suit, proceeding, inquiry, audit, review or investigation before or brought by any court or governmental

(xviii) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering, issuance or sale of the Securities hereunder, the consummation of the transactions contemplated by this Agreement, or for the due execution, delivery or performance of this Agreement, in each case on the terms contemplated by the Registration Statement, the Prospectus and the General Disclosure Package except such as (i) have been already obtained or made, or (ii) may be required under the Act or the Rules and Regulations, the rules of the NASDAQ Stock Market LLC, state securities laws or Financial Industry Regulatory Authority, Inc. (“FINRA”).

(xix) Absence of Manipulation. Neither the Company nor, to the knowledge of the Company any affiliate of the Company has taken, nor will the Company or, to the knowledge of the Company, any affiliate take, directly or indirectly, any action which is designed to or which has constituted or which would be expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(xx) Possession of Licenses and Permits. The Company and its subsidiaries possess such regulatory and quasi-regulatory permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them, except where the failure so to possess would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect; the Company and its subsidiaries are in compliance with the terms and conditions of all such

The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time upon notice by the Representatives to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but shall not be earlier than one business day or later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as the Representatives in their discretion shall make to eliminate any sales or purchases of fractional shares.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company against delivery to the Representatives for the accounts of the Underwriters of certificates for the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase.

If at any time following the issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement or any Preliminary Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus, or the Statutory Prospectus and the Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Representatives, to qualify the Securities for offering and sale under the applicable securities laws of such states and other domestic, or if applicable, foreign, jurisdictions as the Representatives may designate and to maintain such qualifications in effect for a period of not less than one year from the date hereof; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(g) Rule 158. The Company will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the Act.

(h) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Prospectus under “Use of Proceeds”.

(i) Restriction on Sale of Common Stock. During a period of sixty (60) days from the date of the Prospectus, the Company will not, without the prior written consent of the Representatives, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any share of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement or prospectus under the Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (A) the Securities to be sold hereunder, (B) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectus, (C) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to existing employee benefit plans of the Company referred to in the Prospectus, (D) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to any non-employee director stock plan or dividend reinvestment plan (E) any shares of Common Stock issued or sold in connection with any joint venture, partnering or other arrangement with any strategic investor or partner of the Company (provided that the Representatives receive a signed lock-up for the balance of the 60 day period with respect to any such shares of Common Stock so issued or sold), or (F) any shares of Common Stock issued or sold in connection with any acquisition made by the Company (provided that the Representatives receive a signed lock-up for the balance of the 60 day period with respect to any such shares of Common Stock so issued or sold). Notwithstanding the foregoing, if (1) during the last 17 days of the 60-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs or (2) prior to the expiration of the 60-day restricted period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 60-day restricted period, the restrictions imposed in this Section 3(i) shall continue to apply until the expiration of the 18-day period beginning on

the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension. Nothing in this Section 3(i) shall prevent the Company from filing any registration statements on Form S-8 relating to employee benefit plans or on Form S-4 relating to corporate reorganizations or other transactions under Rule 145 where the issuance of the securities being registered thereunder is explicitly permitted by this Section (3)(i).

(j) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the Act, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the Exchange Act Rules and Regulations.

(k) Listing. The Company will use its commercially reasonable efforts to effect and maintain the listing of the Securities on the NASDAQ Global Select Market.

(l) Issuer Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Representatives or by the Company, as the case may be, is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(b) Termination of Agreement. If this Agreement is terminated by the Representatives in accordance with the provisions of Section 5, Section 9(a)(i) or Section 9(a)(iii) hereof, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters

SECTION 6. Indemnification.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 501(b) under the Act (each, an “Affiliate”), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of (A) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of, (B) any untrue statement or alleged untrue statement of a material fact included in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (C) any untrue statement or alleged untrue statement of a material fact included in any materials or information provided to investors by, or with the written approval of, the Company in connection with the marketing of the offering of the Securities, including any road show or investor presentations made to the investors by the Company (whether in person or electronically), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) hereof) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in

investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

(iv) provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus, including the Rule 430B Information, or any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or any Preliminary Prospectus, or any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the following information furnished to the Company by such Underwriter through the Representatives expressly for use therein: the first paragraph under the heading “Underwriting–Commissions and Discounts,” the information in the first and second paragraphs under the heading “Underwriting–Price Stabilization and Short Positions,” the information under the heading “Passive Market Making,” and the information under the heading “Underwriting–Electronic Distribution”.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) hereof, the Company shall be entitled to assume the defense of any action or proceeding with counsel reasonably satisfactory to the indemnified party. Upon assumption by the Company of the defense of any such action or proceeding, the indemnified party shall have the right to participate in such action or proceeding and to retain its own counsel but the Company shall not be liable for any legal expenses of such counsel retained by such indemnified party in connection with the defense thereof unless (i) the Company has agreed to pay such fees and expenses, (ii) the Company shall have failed to employ counsel reasonably satisfactory to the indemnified party in a timely manner, or (iii) the indemnified party shall have been advised by counsel that there are actual or potential conflicting interests between the Company and the indemnified party, including situations in which there are

one or more legal defenses available to the indemnified party that are different from or additional to those available to the Company; provided, however, that the Company shall not, in connection with any one such action or proceeding or separate but substantially similar actions or proceedings in the same jurisdiction arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified parties, including the Underwriters. The Company will not settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding in respect of which indemnification could be sought under this Section 6 or Section 7 hereof (whether or not any Underwriter or any other indemnified party is an actual or potential party to such claim, action or proceeding), unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Except as described below, the Company shall not have any liability with respect to any settlement, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding entered into or made by the Representatives or any other indemnified party in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the Representatives or any other indemnified party is an actual or potential party to such claim, action or proceeding), without the prior written consent of the Company, not to be unreasonably withheld.

If the Representatives or any other indemnified party is requested or required to appear as a witness in any action brought by or on behalf of or against the Company in which such party is not named as a defendant, the Company will reimburse each Underwriter for all expenses incurred in connection with such party’s appearing and preparing to appear as such a witness, including, without limitation, the reasonable fees and disbursements of its legal counsel.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as (x) the total proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and (y) the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, hereof bear to the sum of (x) and (y).

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and the Underwriter’s Affiliates and selling agents, shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.

SECTION 8. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, and any person controlling any Underwriter, its officers or directors, any person controlling the Company, and (ii) delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus (exclusive of any supplement thereto) or the General Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NASDAQ Global Select Market, or (iv) if trading generally on the New York Stock Exchange or in the NASDAQ Global Select Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental agency or body, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe or (vi) if a banking moratorium has been declared by either federal or New York authorities. Notice of any termination of this Agreement shall be promptly given to the Company by telecopy or telephone and shall be subsequently confirmed by letter.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Default. If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements.

In such examination and in rendering the opinions expressed below, we have assumed and relied upon: (i) the due authorization, execution and delivery of the Underwriting Agreement and all other documents by all of the parties thereto (other than the due authorization, execution and delivery of the Underwriting Agreement by the Company); (ii) the genuineness of all signatures on all documents submitted to us; (iii) the authenticity and completeness of all documents, corporate records, certificates and other instruments submitted to us; (iv) that photocopy, electronic, certified, conformed, facsimile and other copies submitted to us of original documents, corporate records, certificates and other instruments conform to the original documents, corporate records, certificates and other instruments, and that all such original documents, corporate records, certificates and other instruments were authentic and complete; (v) the legal capacity of all individuals executing documents; (vi) that the Underwriting Agreement and all other documents executed in connection with the transactions contemplated thereby are the valid and binding obligations of each of the parties thereto (other than the Company), enforceable against such parties (other than the Company) in accordance with their respective terms and that no such documents have been amended or terminated orally or in writing except as has been disclosed to us in writing; (vii) that the statements contained in the certificates and comparable documents of public officials, officers and representatives of the Company and other persons on which we have relied for the purposes of this opinion letter are true and correct and that there has not been any change in the good standing status of the Company from that reported in the Good Standing Certificate and California Good Standing Certificate; (viii) that [each of] the Underwriter[s] has satisfied all regulatory and legal requirements applicable to its activities; and (ix) that for purposes of opinion paragraph 3 with respect to preemptive rights under the General Corporation Law of the State of Delaware (“DGCL”) or the Charter Documents, no change occurs under the DGCL or such Charter Documents after the date hereof.

As to all questions of fact material to this opinion letter and as to the materiality of any fact or other matter referred to herein, we have relied (without independent investigation) upon certificates or comparable documents of officers and representatives of the Company and upon the representations, warranties and covenants contained in the Underwriting Agreement.

Statements in this opinion letter that are qualified by the expression “to our knowledge” or “known to us” or other expressions of like import are limited to the current actual knowledge of Xxxxxx Xxxxxxx, Xxxxxxxx Xxxxxxxx and Xxxxx Xxxxx, the individual attorneys in the firm who have devoted substantive attention to the representation of the Company in connection with the issuance and sale of the Shares and the preparation of the Company’s filings under the Exchange Act. We have not undertaken any independent investigation to determine the accuracy of any such statement, and any limited inquiry undertaken by us during the preparation of this opinion letter should not be regarded as such an investigation. [In rendering the opinion set forth in opinion paragraph 13 below, we have not made any independent investigation of any court, governmental or regulatory records to determine whether any action, suit or proceeding has been filed or is pending.]

Based upon the foregoing, and in reliance thereon, and subject to the limitations, qualifications and exceptions set forth herein, we are of the following opinions:

1.	The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware. The Company has the corporate power and authority (a) to

[Underwriter[s]]

own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Preliminary Prospectus and the Prospectus, (b) to execute and deliver the Underwriting Agreement and to perform its obligations through the Closing Time thereunder, and (c) to issue, sell and deliver the Shares as contemplated under the Underwriting Agreement.

2.	We confirm that the Company is qualified as a foreign corporation to do business as a foreign corporation and is in good standing as a foreign corporation in the State of California as of the date of the California Good Standing Certificate.

The shares of Common Stock being sold pursuant to the Underwriting Agreement have been and, when issued in accordance with the terms of the Underwriting Agreement, will be free of preemptive rights that exist under the DGCL or the Charter Documents and will be validly issued, fully paid and nonassessable.

4.	(a) The execution, delivery and performance of the Underwriting Agreement (including the issuance and sale of the Shares pursuant thereto) have been duly authorized by all necessary corporate action on the part of the Company.

(b) The Underwriting Agreement has been duly executed and delivered by the Company.

5.	As of March 31, 2012, the Company had 250,000,000 shares of Common Stock authorized. As of March 31, 2012, based solely upon review of the Transfer Agent Certificate, the Company had 115,681,825 issued and outstanding shares of Common Stock.

The information (a) incorporated by reference in the Form 8-A under “Item 1—Description of Registrant’s Securities to be Registered”, which is contained in the second and third paragraph under the heading “Description of Capital Stock”, not including the preferred share number in, and the last sentence of, such third paragraph, (b) in the Base Prospectus under the heading “Description of Capital Stock”, and (c) in the Preliminary Prospectus Supplement and the Prospectus Supplement under the heading “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders”, insofar as they purport to constitute matters of law, summaries of legal matters, agreements, documents or proceedings referred to therein, fairly and accurately summarize the legal matters, agreements, documents or proceedings described therein in all material respects.

The Registration Statement, including without limitation the Rule 430B Information, on its effective date and on each deemed effective date prior to the date hereof with respect to the Underwriter[s] pursuant to Rule 430B(f)(2) under the Securities Act, the Preliminary Prospectus as of the date thereof and the Prospectus as of the date of the Prospectus Supplement (other than, in each case, the financial statements, notes and schedules thereto and other information of a financial, accounting or statistical nature included or incorporated by reference therein, as to which we express no opinion), appear on their face to comply as to form in all material respects with the applicable requirements of the Securities Act and the rules and regulations promulgated thereunder.

Each of the Incorporated Documents, as of the date on which it was filed with the Commission (other than, in each case, the financial statements, notes and schedules thereto and other information of a financial, accounting or statistical nature included or incorporated by reference therein, as to which we express no opinion), appears on its face to comply as to form in all material respects with the then-applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder.

Based solely on the Commission Notice of Effectiveness, the Registration Statement has become effective under the Securities Act; any required filing of the Preliminary Prospectus and the Prospectus pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by Rule 424(b) (without reference to Rule 424(b)(8)); [any required filing of the Issuer Free Writing Prospectus set forth on Schedule I hereto pursuant to Rule 433 under the Securities Act has been made in the manner and within the time period required by Rule 433(d);] to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and, to our knowledge, no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

10.

No consent, registration, qualification, approval, authorization or order of or filing with any federal, California or New York governmental authority or, to our knowledge, any California, New York or federal court is required for the Company’s due authorization, execution and delivery of the Underwriting Agreement and the issuance, sale or delivery of the Shares pursuant thereto, other than (a) those that have been obtained under the Securities Act, the Exchange Act or the rules of the NASDAQ Stock Market LLC, and (b) those under state securities or blue sky laws (as to which we express no opinion).

11.

The execution and delivery of the Underwriting Agreement and the performance by the Company through the Closing Time of its obligations thereunder, and the issuance and delivery of the Shares by the Company pursuant to the Underwriting Agreement do not (a) violate any provisions of the Charter Documents; (b) constitute a material breach by the Company of, or constitute a material default by the Company under, or constitute a Repayment Event (as defined in Section 1[(a)(xii)] of the Underwriting Agreement) by the Company under, any of the agreements listed as an exhibit to the Annual Report; (c) cause the Company to violate any federal or California or New York law, regulation or rule (other than state securities or blue sky laws, as to which we express no opinion) applicable to the Company; or (d) cause the Company to violate any decree, judgment or order of any federal, California or New York state court, government or governmental instrumentality applicable to the Company which is known to us.

12.

[To our knowledge, there are no contracts, licenses, agreements, leases or other documents of a character which are required to be filed as exhibits to the Registration Statement as of its date or to be summarized or described in the Registration Statement as of its date, the Preliminary Prospectus or the Prospectus which are not so filed, summarized or described, as applicable.]

13.

[To our knowledge, there is no action, suit or proceeding at law or in equity, or by or before any federal or California state court or governmental or regulatory body or agency or arbitration board or panel pending or overtly threatened against the Company, which is required to be described in the Preliminary Prospectus or the Prospectus but is not so described therein [or in the documents incorporated by reference therein].]

14.

The Company is not and, immediately after giving effect to the offer and sale of the Shares and the use of the proceeds therefrom as contemplated by the Underwriting Agreement and described in the Preliminary Prospectus or the Prospectus, will not be an “investment company” or an entity “controlled” by an “investment company”, as such terms are defined in the Investment Company Act of 1940, as amended.

Notwithstanding the foregoing and subject to the conditions below, the undersigned may transfer the Lock-Up Securities without the prior written consent of the Representatives, provided that (1) the Representatives receive a signed lock-up agreement for the balance of the lock-up period from each donee, trustee, distribute, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported in any public report or filing with the Securities and Exchange Commission, or otherwise, and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers:

In addition, notwithstanding the lock-up restrictions described in the first paragraph of this lock-up agreement, the undersigned shall be permitted, pursuant to a written trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which exists as of the date of this lock-up agreement (a “Plan”), to sell, only pursuant to such Plan, shares of Common Stock prior to the expiration of the Lock-Up Period. In addition, the undersigned agrees that, without the prior written consent of the Representatives, it will not, during the period beginning on the date hereof and ending on the date that is 60 days after the date of the Underwriting Agreement, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock.

Additionally, the restriction in the second sentence of the first paragraph of this lock-up agreement shall not apply to the exercise of stock options held by the undersigned as of the date hereof (provided that the shares of common stock received upon exercise shall continue to be deemed Lock-Up Securities for all purposes under this Agreement).

(2) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the Lock-Up Period,

the restrictions imposed by this lock-up agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Representatives waive, in writing, such extension.

The undersigned hereby acknowledges and agrees that written notice of any extension of the Lock-Up Period pursuant to the previous paragraph will be delivered by the Representatives to the Company (in accordance with the Underwriting Agreement) and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned.
