IN THE COURT OF CHANCERY OF THE STATE OF DELAWARE

STIPULATION OF COMPROMISE AND SETTLEMENT

This Stipulation of Compromise and Settlement (the "Stipulation") is made and entered into as of February 8, 2024, between and among: (a) plaintiffs Elaine Wang ("Wang") and Bill Tsantes ("Tsantes" and collectively with Wang, "Plaintiffs"), on behalf of nominal defendant BioMarin Pharmaceuticals Inc. ("BioMarin" or the "Company"), in the above-captioned stockholder derivative actions (the "Derivative Actions"), (b) individual defendants Jean-Jacques Bienaimé

("Bienaimé"), Elizabeth McKee Anderson, Willard Dere, Elaine J. Heron, Robert Hombach, Bryan Lawlis, Richard A. Meier, David E. I. Pyott, Dennis J. Slamon, Michael Grey, Mark J. Alles, Maykin Ho, and Henry J. Fuchs ("Fuchs") (the "Individual Defendants"), and (c) nominal defendant BioMarin (together with the Individual Defendants, the "Defendants," and collectively with Plaintiffs, the "Parties" and each a "Party"). This Stipulation sets for the terms of and conditions of the settlement of the Derivative Actions (the "Settlement"), subject to the approval of the Court of Chancery of the State of Delaware (the "Court"), and is intended to fully, finally, and forever compromise, discharge, resolve, release and settle the Released Claims (as defined in paragraph 1.10 below).

SUMMARY OF THE PROCEEDINGS

A. Plaintiffs in the Derivative Actions allege that the Individual Defendants breached their fiduciary duties to BioMarin, and engaged in other wrongdoing, by, inter alia, failing to adequately exercise oversight over the Company to prevent the issuance of materially false and misleading statements concerning the Company's application to the United States Food and Drug Administration (the "FDA") for approval of its "Valrox" gene therapy, and selling BioMarin stock at artificially inflated prices while in possession of material, non-public Company information.

3

B. On May 4, 2021, Tsantes, a BioMarin stockholder, served BioMarin with a demand for the inspection of books and records pursuant to 8 Del. C. § 220 ("§ 220") concerning potential wrongdoing in connection with various statements issued regarding Valrox. In response thereto, after BioMarin and Tsantes negotiated the scope of a document production and entered into a confidentiality agreement, the Company produced 1,902 pages of internal, non-public Company documents to Tsantes, which counsel for Tsantes reviewed and analyzed.

C. On March 14, 2022, Tsantes, through his counsel, served a pre-suit litigation demand (the "Litigation Demand") on BioMarin's Board of Directors (the "Board"), which included certain allegations based on the confidential § 220 materials, demanding that the Board cause the Company to file an action against defendants Bienaimé and Fuchs for breach of fiduciary duty, contribution, and indemnification. The Litigation Demand also demanded that the Board commence an independent investigation in good faith into the events regarding alleged breaches of fiduciary duties by other current and/or former officers and directors of the Company. The Litigation Demand further demanded that the Board cause BioMarin to enter into tolling agreements with each individual implicated in the alleged wrongdoing to preserve the Company's claims during the pendency of the Board's investigation.

4

D. On April 25, 2022, Wang, a BioMarin stockholder, served BioMarin with a demand for the inspection of books and records pursuant to § 220. In response thereto, after BioMarin and Wang negotiated the scope of a document production and entered into a confidentiality agreement, the Company produced 1,248 pages of internal, non-public Company documents to Wang, which counsel for Wang reviewed and analyzed.

E. On June 1, 2022, the Company responded to Tsantes' Litigation Demand, stating that the Board determined it was in the best interests of the Company to defer consideration of the Litigation Demand during the pendency of a related federal securities class action, BioMarin Pharmaceutical Inc. Securities Litigation, 3:20-cv-06719-WHO (N.D. Cal.) (the "Securities Class Action").

F. On January 19, 2023, Wang filed a Confidential Verified Stockholder Derivative Complaint in the action Wang v. Bienaimé, et al., C.A. No. 2023-0058-NAC (the "Wang Action"), putatively on behalf of the Company alleging, among other things, that the Individual Defendants breached their fiduciary duties. Certain of the allegations in the Wang Action are based on the confidential § 220 materials.

G. On March 1, 2023, Defendants filed a motion to dismiss the complaint in the Wang Action (the "Motion to Dismiss") pursuant to Court of Chancery Rules 23.1 ("Rule 23.1"), 12(b)(1), and 12(b)(6).

5

H. While the parties to the Wang Action were discussing a mutually agreeable briefing schedule in connection with the Motion to Dismiss, the parties in the Securities Class Action reached a proposed settlement, and, on April 28, 2023, moved for preliminary approval of that settlement. The settlement of the Securities Class Action provides for a cash payment of $39,000,000.00 to the settlement class.¹

I. On June 2, 2023, Tsantes filed a Confidential Verified Stockholder Derivative Complaint in the action Tsantes v. Bienaimé, et al., C.A. No. 2023-0569-NAC (the "Tsantes Action"), on behalf of the Company alleging, among other things, that the Individual Defendants breached their fiduciary duties. Certain of the allegations in the Tsantes Action are based on the confidential § 220 materials.

J. Shortly thereafter, Plaintiffs agreed to work cooperatively to attempt to negotiate a resolution of the claims asserted in the Derivative Actions and, in or about July 2023, commenced negotiations with Defendants.

K. The negotiations between the Parties continued for several months and, in October 2023, the Parties agreed to schedule a mediation with Michelle Yoshida, Esq. ("Ms. Yoshida" or the "Mediator") of Phillips ADR Enterprises ("PADRE") to take place on November 9, 2023. Ms. Yoshida served as the mediator in connection with the Securities Class Action settlement.

6

L. The Parties continued negotiations regarding the substantive terms of the Settlement and, on November 6, 2023, reached an agreement-in-principle regarding those terms.

M. Ms. Yoshida was provided with the substantive terms of the Settlement by the Parties and, on November 9, 2023, conducted a full day mediation session (the "Mediation") with the Parties concerning the amount of attorneys' fees and expenses to be paid to Plaintiffs' Counsel (defined herein) in consideration of the substantial benefits achieved for the Company and its current stockholders through the filing, litigation, and settlement of the Derivative Actions. By the conclusion of the Mediation, the Parties had reached an impasse and the Mediation session ended with no agreement reached by the Parties.

N. On November 10, 2023, Ms. Yoshida issued a double-blind mediator's recommendation to the Parties (the "Mediator's Proposal"). The Mediator's Proposal recommended the payment of $1,250,000.00 in attorneys' fees and expenses to Plaintiffs' Counsel, subject to approval by the Court. The Parties accepted the Mediator's Proposal on November 10, 2023.

7

O. The Parties agree that Plaintiffs commenced and pursued the Derivative Actions in good faith, including the Litigation Demand and Plaintiffs' pre-litigation inspection demand efforts. Plaintiffs maintain that entry by Plaintiffs into this Stipulation is not an admission as to the lack of any merit of any claims asserted by Plaintiffs in the Derivative Actions.

JJ. Defendants have denied, and continue to deny, that they committed any breach of duty, violated any law, or engaged in any wrongdoing, expressly maintain that they diligently and scrupulously complied with their fiduciary and other legal duties, to the extent such duties exist, and further believe that the Derivative Actions are without merit. Defendants are entering into this Stipulation to eliminate the uncertainty, burden and expense of further protracted litigation. This Stipulation shall in no event be construed or deemed to be evidence of or an admission or concession on the part of any of the Defendants, with respect to any claim or allegation of any fault or liability or wrongdoing or damage whatsoever, or any infirmity in the defenses that Defendants have, or could have, asserted in the Derivative Actions. Defendants expressly deny that Plaintiffs have asserted any valid claims as to any of them, and expressly deny any and all allegations of fault, liability, wrongdoing or damages whatsoever.

NOW, THEREFORE, IT IS HEREBY STIPULATED AND AGREED, BY AND AMONG THE PARTIES TO THIS STIPULATION, subject to the approval of the Court pursuant to Rule 23.1, that the Derivative Actions shall be fully and finally compromised and settled, that the Released Claims shall be released by the

17

COOPERATION

18. The Parties and their respective counsel agree to cooperate fully with one another in seeking the Court's approval of the Settlement, and to use their best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things reasonably necessary, proper, or advisable under applicable laws, regulations, and agreements to obtain the Court's approval of the Settlement, consummate and make effective, as promptly as practicable, this Stipulation and the Settlement provided for hereunder (including, but not limited to, using their best efforts to resolve any objections raised to the Settlement) and the dismissal of the Derivative Actions with prejudice without costs, fees or expenses to any Party (except as provided for herein).

19. Without further order of the Court, the Parties may agree to reasonable extensions of time not expressly set forth by the Court in order to carry out any provisions of this Stipulation.

CONDITIONS OF SETTLEMENT

20. The Settlement is conditioned upon the fulfillment of each of the following:

20.1 The entry by the Court of an Order and Final Judgment in the form attached hereto as Exhibit D approving the proposed Settlement and dismissing the Derivative Actions with prejudice without the award of any damages, costs, fees or the grant of any further relief except for an award of fees and expenses to Plaintiffs' Counsel that the Court may make as contemplated herein.

20.2 Final Approval of the Settlement.

18

21. Each of BioMarin and the Individual Defendants shall have the right to withdraw from the Settlement in the event that any claims related to the subject matter of the Derivative Actions are commenced or prosecuted against any of the Released Defendant Parties in any court prior to Final Approval of the Settlement and such claims are not dismissed with prejudice or stayed in contemplation of dismissal following Final Approval of the Settlement. In the event such claims are commenced, the Parties agree to cooperate and use their reasonable best efforts to secure the dismissal thereof or a stay in contemplation of dismissal following Final Approval of the Settlement. This Stipulation shall be null and void and of no force and effect if the Settlement does not obtain Final Approval for any reason. In such event, this Stipulation shall not be deemed to prejudice in any way the respective positions of the Parties with respect to the Derivative Actions or to entitle any Party to the recovery of costs and expenses incurred in connection with the intended implementation of the Settlement, including any costs related to providing notice to Applicable BioMarin Stockholders (as set forth in paragraph 14), to the extent such costs have already been incurred by BioMarin.

22. In the event that the proposed Settlement is rendered null and void for any reason, the existence of or the provisions contained in this Stipulation or any term sheet or other document relating to the terms of the proposed Settlement shall not be deemed to prejudice in any way the respective positions of the Parties with respect to the Derivative Actions; nor shall they be deemed a presumption, a concession, or

19

an admission by the Parties of any fault, liability, wrongdoing or damages whatsoever as to any facts, claims or defenses that have been or could have been alleged or asserted in the Derivative Actions, or any other action or proceeding or each thereof; nor shall they be interpreted, construed, deemed, invoked, offered, or received in evidence or otherwise used by any person in the Derivative Actions, or in any other action or proceeding.

WARRANTY AND NON-ASSIGNMENT OF CLAIMS

23. Plaintiffs and Plaintiffs' Counsel represent and warrant that Plaintiffs are current BioMarin stockholders and that none of Defendants' Released Claims have been assigned, encumbered, or in any manner transferred in whole or in part, and that neither Plaintiffs nor Plaintiffs' Counsel will attempt to assign, encumber, or in any way transfer, in whole or in part, any of Defendants' Released Claims.

ATTORNEYS' FEES AND REIMBURSEMENT OF EXPENSES FOR PLAINTIFFS' COUNSEL

24. After negotiation of the principal terms of the Settlement, including the Corporate Governance Reforms and the definition of Released Claims, the Parties participated in the full-day Mediation session with the assistance of Ms. Yoshida of PADRE. By the conclusion of the Mediation, the Parties were at an impasse and were unable to reach an agreement on the amount of attorneys' fees and expenses for Plaintiffs' Counsel in connection with the proposed Settlement of the Derivative

20

Actions. After the Parties reached that impasse, Ms. Yoshida issued the double-blind Mediator's Proposal to the Parties. Pursuant to the Mediator's Proposal, the Parties agreed that Plaintiffs' Counsel shall receive an award of attorneys' fees and expenses in the amount of $1,250,000.00 in the aggregate (the "Fee Award"), subject to Court approval, and that Defendants will not oppose or object to the proposed Fee Award.

25. The Court may consider and rule upon the fairness, reasonableness, and adequacy of the proposed Settlement independently of Plaintiffs' Counsel's proposed Fee Award. The failure of the Court to approve the proposed Fee Award, in whole or in part, shall have no effect on the validity of the Settlement or delay the enforceability of the Settlement, and final resolution by the Court of the proposed Fee Award shall not be a precondition to the dismissal with prejudice of the Derivative Actions. Any failure of the Court to approve the proposed Fee Award, in whole or in part, shall not provide any of the Parties with the right to terminate the Settlement.

26. BioMarin's insurer(s) shall pay and/or cause to be paid any fee award entered by the Court as provided by the terms of such order within twenty (20) business days of entry of such order and Plaintiffs' Counsel providing BioMarin's counsel with the necessary information required for payment by check or a wire-transfer, including a signed W-9 and a tax ID number, with the Fee Award to be held in the escrow account of Rigrodsky Law, P.A. No payments shall be made from the escrow account of Rigrodsky Law, P.A. until allocation of the Fee Award has been resolved pursuant

21

to paragraph 28 of this Stipulation. Any payment of any fee award provided herein shall be subject to Plaintiffs' Counsel's obligation to make refunds or repayments to BioMarin of any amounts paid, if the Settlement is terminated pursuant to the terms of this Stipulation or fails to become effective for any reason, or if, as a result of any appeal of further proceedings on remand or successful collateral attack, the award of attorneys' fees and/or expenses is reduced or reversed by final non-appealable court order.

27. Plaintiffs may seek the Court's approval of reasonable service awards for each Plaintiff of up to $2,000.00, to be paid from the Fee Award, and Defendants shall not oppose any such request.

28. Plaintiffs' Counsel shall allocate the Fee Award among themselves.

STIPULATION NOT AN ADMISSION

29. Neither this Stipulation nor the Settlement, nor any act or omission taken in connection with this Stipulation or the Settlement, is intended or shall be deemed to be a presumption, concession or admission by: (a) any of the Individual Defendants or any of the Released Defendant Parties as to the validity of any claims, causes of action or other issues that were or could have been raised in the Derivative Actions or in any other litigation, or to be evidence of or constitute an admission of wrongdoing or liability by any of them, and each of them expressly denies any such wrongdoing or liability; or (b) Plaintiffs as to the lack of merit of any claim or the validity of any defense.

22

30. Any communications related to the Settlement, their contents or any of the negotiations, statements, or proceedings in connection therewith shall not be offered or admitted in evidence or referred to, interpreted, construed, invoked, or otherwise used by any person for any purpose in the Derivative Actions or otherwise, except as may be necessary to effectuate the Settlement.

31. Paragraphs 21, 22, 29 and 30 shall remain in full force and effect in the event that the proposed Settlement is terminated or fails to become effective for any reason.

NO WAIVER

32. Any failure by any Party to insist upon the strict performance by any other Party of any of the provisions of the Settlement shall not be deemed a waiver of any of the provisions of the Settlement, and such Party shall have the right thereafter to insist upon the strict performance of any and all of the provisions of the Settlement. All waivers must be in writing and signed by the Party against whom the waiver is asserted.

33. No waiver, express or implied, by any Party of any breach or default in the performance by any other Party of its obligations pursuant to the Settlement shall be deemed or construed to be a waiver of any other breach, whether prior, subsequent or contemporaneous, under the terms of the Settlement.

23

BREACH

34. The Parties agree that in the event of any breach of the Settlement, all of the Parties' rights and remedies at law, equity, or otherwise, are expressly reserved.

GOVERNING LAW

35. This Stipulation and the Settlement contemplated by it shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to conflict of laws principles.

WHAT IS THIS CASE ABOUT? WHAT HAS HAPPENED SO FAR?

THE FOLLOWING RECITATION DOES NOT CONSTITUTE FINDINGS OF THE COURT AND SHOULD NOT BE UNDERSTOOD AS AN EXPRESSION OF ANY OPINION OF THE COURT AS TO THE MERITS OF ANY CLAIMS OR DEFENSES BY ANY OF THE PARTIES. IT IS BASED ON STATEMENTS OF THE PARTIES AND IS SENT FOR THE SOLE PURPOSE OF INFORMING YOU OF THE EXISTENCE OF THE DERIVATIVE ACTIONS AND OF A HEARING ON A PROPOSED SETTLEMENT SO THAT YOU MAY MAKE APPROPRIATE DECISIONS AS TO STEPS YOU MAY, OR MAY NOT, WISH TO TAKE IN RELATION TO THIS LITIGATION.

5. BioMarin, a publicly traded Delaware corporation with its principal executive offices located in San Rafael, California, is a pharmaceutical company that developed Valrox, a gene therapy treatment for hemophilia A, a hereditary disease caused by the lack of a blood clotting protein called "Factor VII."

- 4 -

6. Plaintiffs allege that between March 3, 2020 and August 18, 2020 (the "Relevant Period"), Defendants¸ among other things, breached their fiduciary duties by issuing, and/or permitting the issuance of, materially false and misleading statements regarding the status of the U.S. Food and Drug Administration's (the "FDA") approval process for Valrox. Plaintiffs allege that the Individual Defendants failed to disclose that the FDA had informed the Company in June 2020 that approval of Valrox by August 2020, the deadline under the Prescription Drug User Fee Act, was virtually impossible.

7. On August 19, 2020, the Company announced that the FDA would not approve Valrox at that time. On this news, BioMarin stock dropped by $41.82 per share, or 35%, to close at $76.72 per share on August 19, 2020.

8. On May 4, 2021, Tsantes, a BioMarin stockholder, served BioMarin with a demand for the inspection of books and records pursuant to 8 Del. C. § 220 ("§ 220") concerning potential wrongdoing in connection with various statements issued regarding Valrox. In response thereto, after BioMarin and Tsantes negotiated the scope of a document production and entered into a confidentiality agreement, the Company produced 1,902 pages of internal, non-public Company documents to Tsantes, which counsel for Tsantes reviewed and analyzed.

9. On March 14, 2022, Tsantes, through his counsel, served a pre-suit litigation demand (the "Litigation Demand") on BioMarin's Board of Directors (the "Board"), which included certain allegations based on the confidential § 220 materials, demanding that the Board cause the Company to file an action against defendants Bienaimé and Fuchs for breach of fiduciary duty, contribution, and indemnification. The Litigation Demand also demanded that the Board commence an independent investigation in good faith into the events regarding alleged breaches of fiduciary duties by other current and/or former officers and directors of the Company. The Litigation Demand further demanded that the Board cause BioMarin to enter into tolling agreements with each individual implicated in the alleged wrongdoing to preserve the Company's claims during the pendency of the Board's investigation.

10. On April 25, 2022, Wang, a BioMarin stockholder, served BioMarin with a demand for the inspection of books and records pursuant to § 220. In response thereto, after BioMarin and Wang negotiated the scope of a document production and entered into a confidentiality agreement, the Company produced 1,248 pages of internal, non-public Company documents to Wang, which counsel for Wang reviewed and analyzed.

- 5 -

11. On June 1, 2022, the Company responded to Tsantes' Litigation Demand, stating that the Board determined it was in the best interests of the Company to defer consideration of the Litigation Demand during the pendency of a related federal securities class action, BioMarin Pharmaceutical Inc. Securities Litigation, 3:20-cv-06719-WHO (N.D. Cal.) (the "Securities Class Action").

12. On January 19, 2023, Wang filed a Confidential Verified Stockholder Derivative Complaint in the action Wang v. Bienaimé, et al., C.A. No. 2023-0058- NAC (the "Wang Action"), on behalf of the Company alleging, among other things, that the Individual Defendants breached their fiduciary duties. Certain of the allegations in the Wang Action are based on the confidential § 220 materials.

13. On March 1, 2023, Defendants filed a motion to dismiss the complaint in the Wang Action (the "Motion to Dismiss") pursuant to Court of Chancery Rules 23.1 ("Rule 23.1"), 12(b)(1), and 12(b)(6).

14. While the parties to the Wang Action were discussing a mutually agreeable briefing schedule in connection with the Motion to Dismiss, the parties in the Securities Class Action reached a proposed settlement, and, on April 28, 2023, moved for preliminary approval of that settlement. The settlement of the Securities Class Action provides for a cash payment of $39,000,000.00 to the class.

15. A hearing on the motion for final approval of the settlement of the Securities Class Action was conducted on November 8, 2023. That same day, the United States District Court for the Northern District of California entered a Minute Order that states "[t]he Court finds the settlement to be fair, adequate, and reasonable and anticipates granting final approval." See3:20-cv-06719-WHO, ECF No, 153. The order granting final approval of the Securities Class Action settlement was entered on November 14, 2023.

16. On June 2, 2023, Tsantes filed a Confidential Verified Stockholder Derivative Complaint in the action Tsantes v. Bienaimé, et al., C.A. No. 2023-0569- NAC (the "Tsantes Action"), on behalf of the Company alleging, among other things, that the Individual Defendants breached their fiduciary duties. Certain of the allegations in the Tsantes Action are based on the confidential § 220 materials.

17. Shortly thereafter, Plaintiffs agreed to work cooperatively to attempt to negotiate a resolution of the claims asserted in the Derivative Actions and, in or about July 2023, commenced negotiations with Defendants.

18. The negotiations between the Parties continued for several months and, in October 2023, the Parties agreed to schedule a mediation with Michelle Yoshida, Esq. ("Ms. Yoshida" or the "Mediator") of Phillips ADR Enterprises ("PADRE") to take place on November 9, 2023. Ms. Yoshida served as the mediator in connection with the Securities Class Action settlement.

- 6 -

19. The Parties continued negotiations regarding the substantive terms of the Settlement and, on November 6, 2023, reached an agreement-in-principle regarding those terms.

20. Ms. Yoshida was provided with the substantive terms of the Settlement by the Parties and, on November 9, 2023, conducted a full day mediation session (the "Mediation") with the Parties concerning the amount of attorneys' fees and expenses to be paid to Plaintiffs' Counsel (defined herein) in consideration of the substantial benefits achieved for the Company and its current stockholders through the filing, litigation, and settlement of the Derivative Actions. By the conclusion of the Mediation, the Parties had reached an impasse and the Mediation session ended with no agreement reached by the Parties.

21. On November 10, 2023, Ms. Yoshida issued a double-blind mediator's recommendation to the Parties (the "Mediator's Proposal"). The Mediator's Proposal recommended the payment of $1,250,000.00 in attorneys' fees and expenses to Plaintiffs' Counsel, subject to approval by the Court. The Parties accepted the Mediator's Proposal on November 10, 2023.

22. The Parties executed the Stipulation on March 27, 2024.

WHAT ARE THE TERMS OF THE SETTLEMENT?

23. Set forth below is a summary of the principal terms of the proposed Settlement, as agreed to by the Parties, subject to the approval of the Court. The following statements are a summary, and reference is made to the Stipulation, which is publicly available as indicated in paragraph 37 below, for a full and complete statement of the terms of the Settlement.

WHAT ARE THE PARTIES' REASONS FOR THE SETTLEMENT?

26. The Settlement set forth in the Stipulation reflects the results of the Parties' negotiations and the terms of the Stipulation, and an agreement-in-principle was reached only after arm's-length negotiations, with the assistance of-and following a mediator's proposal from-Ms. Yoshida as mediator, among the Parties, all of which were represented by counsel with extensive experience and expertise in stockholder derivative litigation.

27. Plaintiffs believe that the Released Claims had merit when filed and continue to have merit, and Plaintiffs are settling the Released Claims because Plaintiffs believe that the Settlement will provide substantial value to the Company and its stockholders. Plaintiffs have concluded that the Settlement is fair, reasonable, and in the best interests of the Company and its stockholders, and that it is reasonable to pursue the Settlement based on the terms and procedures outlined in the Stipulation.

28. Defendants have denied, and continue to deny, that they have committed or threatened to commit any violations of law, breaches of duty, breaches of contract, or other wrongdoing toward the Company, Plaintiffs, or anyone else concerning any of the claims, allegations, or requests for relief set forth in the complaints filed in these Derivative Actions.

- 14 -

29. If the Settlement is approved, the Court will enter an order approving the Settlement in accordance with the Stipulation, at which time the Derivative Actions will be dismissed with prejudice on the merits. The first date by which such order is finally affirmed on appeal or is no longer subject to appeal, and the time for any petition for re-argument, appeal or review, by leave, writ of certiorari, or otherwise, has expired, constitutes "Final Approval." Upon receipt of Final Approval, and subject to the conditions set forth in the Stipulation, the following releases will occur:

The Released Parties shall be deemed to have, and by operation of the Order and Final Judgment approving the Settlement shall have, completely discharged, dismissed with prejudice on the merits, released and settled, to the fullest extent permitted by law, the Released Claims against the Released Parties (as defined below) and shall be forever barred and enjoined from commencing, instituting, prosecuting, or continuing to prosecute any of the Released Claims against any of the Released Parties.

The obligations incurred pursuant to the Stipulation shall be in full and final disposition of the Derivative Actions and each of the Released Claims. It is the intention of the Parties that the Settlement eliminate all further risk and liability relating to the Released Claims, and that the Settlement shall be a final and complete resolution of all claims asserted or which could be or could have been asserted with respect to the Released Claims against any of the Released Parties, including without limitation any claims for contribution in accordance with 10 Del. C. § 6304 and any similar laws or statutes.

"Released Claims" means Plaintiffs' Released Claims and Defendants' Released Claims; provided, however, for the avoidance of doubt, that Released Claims shall not include any claims relating to the enforcement of this Stipulation or Settlement or any claims by BioMarin or the Individual Defendants for insurance coverage or any claims by the Individual Defendants for indemnification or advancement.

"Released Defendant Parties" means all Defendants in the Derivative Actions, and any and all of their and BioMarin's respective current or former agents, parents, controlling persons, general or limited partners, members, managers, managing members, direct or indirect equity holders, subsidiaries, affiliates, employees, officers, directors, predecessors, successors, attorneys, heirs, assigns, insurers, reinsurers, consultants, and other representatives, servants and related persons, in their capacities as such.

- 15 -

"Plaintiffs' Released Claims" means all claims and causes of action of every nature and description, whether known or unknown, whether arising under federal, state, common or foreign law, including Unknown Claims, that arise out of or relate in any way to Released Plaintiff Parties' (as defined below) institution, prosecution, or settlement of the Derivative Actions.

"Released Plaintiff Parties" means Plaintiffs and Plaintiffs' Counsel and each of their respective agents, assigns, and related persons.

"Released Party" or "Released Parties" means each and all of the Released Plaintiff Parties and the Released Defendant Parties.

"Released Parties" means the Released Plaintiff Parties and the Released Defendant Parties, individually or collectively as the context may require.

The Settlement is intended to extinguish all of the Released Claims by the Releasing Parties as against the Released Parties and, consistent with such intention, upon Final Approval of the Settlement, the Releasing Parties shall waive and relinquish, to the fullest extent permitted by law, the provisions, rights, and benefits of any state, federal, or foreign law or principle of common law, which may have the effect of limiting the Released Claims. This shall include a waiver of any rights pursuant to California Civil Code § 1542 (and equivalent, comparable, or analogous provisions of the laws of the United States or any state or territory thereof, or of the common law), which provides:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, AND THAT IF KNOWN BY HIM OR HER WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR THE RELEASED PARTY.

30. If the Settlement is approved and Final Approval occurs, since the Company will have released the Released Claims described above against the Released Parties, no Company stockholder will be able to bring another action asserting those claims against those persons on behalf of the Company or individually.

- 16 -

31. Pending final determination of whether the Settlement should be approved, all proceedings in the Derivative Actions, other than such proceedings as may be necessary to carry out the terms and conditions of the Settlement and determine a fee award, have been stayed and suspended. Subject to an Order of the Court, until the earlier of Final Approval (defined below) or an order of the Court substantially denying or declining to approve the Settlement in accordance with the Stipulation, the Released Parties, or any individual, are barred and enjoined to the maximum extent permitted under law from commencing, prosecuting, instigating, or in any way participating in the commencement or prosecution of any action asserting any of the Released Claims, either directly, representatively, derivatively or in any other capacity, against any of the Released Parties. The Parties agree to use their best efforts to prevent, stay, seek dismissal of, or oppose entry of any interim or final relief in favor of any of the Released Parties in any other litigation against any of the Released Parties or their affiliates that challenges the Settlement or brings claims, the release of which are contemplated by the Stipulation.

32. "Final Approval" means the later of (a) the expiration of the time for the filing or noticing of an appeal or motion for reargument or rehearing from the Court's Order and Final Judgment approving the Settlement; (b) the date of final affirmance of the Court's Order and Final Judgment on any appeal or reargument or rehearing; or (c) the final dismissal of any appeal.

HOW WILL THE ATTORNEYS BE PAID?

33. Concurrent with seeking final approval of the Settlement, Plaintiffs' Counsel intends to petition the Court for an award of attorneys' fees and expenses not to exceed $1,250,000. Plaintiffs' Counsel also intends to seek a Service Award of up to $2,000.00 to be paid to each Plaintiff for their reasonable efforts in prosecuting the Derivative Actions. Any such Service Award shall be paid out of the Fee Award granted to Plaintiffs' Counsel. Defendants agree not to object or oppose the requested Fee Award. Plaintiffs' Counsel will make this petition not less than thirty (30) calendar days prior to the Settlement Hearing.

34. Any award to Plaintiffs' Counsel for fees and expenses and any service fee to Plaintiffs shall be determined by the Court.

- 17 -

WHEN AND WHERE WILL THE SETTLEMENT HEARING BE HELD? DO
