(a) Ultragenyx (on its own or acting through any of its Affiliates, sublicensees or subcontractors) shall use Commercially Reasonable Efforts to develop and commercialize at least one (1) Product in FAOD and at least (1) Product in [***]. Specifically, Ultragenyx will use Commercially Reasonable Efforts to (a) [***]; (b) [***]; (c) [***]; and (d) within [***] after the Effective Date, perform at least one of the following: (i) [***]; or (ii) [***]; in each case of (a)-(d) above, provided that each such timeline shall be extended to account for any delay resulting from factors beyond Ultragenyx’s reasonable control, including regulatory, medical, safety or efficacy delays.

(b) If Ultragenyx shall fail to achieve such milestones within such applicable time frame(s) (as such time frame(s) may be extended pursuant to 3.2(a) above), BRI may provide written notice to Ultragenyx and upon receipt of any such notice, the Parties shall discuss in good faith Ultragenyx’s progress for the development of such Product in the

applicable jurisdiction and the Parties may agree on an amended timeline or a plan for Ultragenyx to continue its development of the Product. Each agreed upon [***] extension of the timeline shall be subject to the payment by Ultragenyx of an extension fee of [***]. For clarity, if a delay in timeline is due to new regulatory, development, or safety requirements or other similar actions by regulatory authorities or other government agencies, such timeline is not subject to the payment by Ultragenyx of an extension fee.

(c) For the purposes of this Section 3.2(c), all FAOD indications shall be deemed one “Indication Cluster” and all [***] shall be deemed another “Indication Cluster.” On an Indication Cluster-by-Indication Cluster basis, in the event Ultragenyx fails to satisfy such new timeline or plan that is specific to a particular Indication Cluster, then upon written notice by BRI, the license granted to Ultragenyx pursuant to Section 2.1(a) shall become non-exclusive solely for such Indication Cluster, provided that all obligations for payment of royalties or milestones remain the same for such Indication Cluster and provided, that, if Ultragenyx subsequently obtains Regulatory Approval for the Product for such Indication Cluster, the license under Section 2.1(a) shall thereupon automatically convert back to an exclusive license for such Indication Cluster so long as BRI still maintains the right to grant an exclusive license to Ultragenyx at such time. In the event of the conversion of the license to non-exclusive, any sole and/or exclusive rights that Ultragenyx has under this Agreement with respect to such non-exclusive Indication Cluster, including without limitation such rights under Section 3.1, this Section 3.2, and Section 3.3 shall also automatically become non-exclusive. Further, on an Indication Cluster-by-Indication Cluster basis, Ultragenyx’s rights regarding BRI Independent Studies under Sections 3.3 (i)-(iv), and Ultragenyx’s rights under Sections 5.1(a), 5.3(b), Section 5.4(b), Section 5.5 (a) and (b), and Section 5.6, as well as BRI’s corresponding obligations to Ultragenyx with respect to those Sections, in each case as such rights and obligations apply to any non-exclusive Indication Cluster, shall be suspended for so long as such license remains non-exclusive and shall be automatically reinstated if and when such license becomes exclusive pursuant to the foregoing. Failure to achieve such milestones shall not be a material breach of this Agreement. The remedy provided for pursuant to this Section 3.2 shall be BRI’s sole and exclusive remedy for or relating to Ultragenyx’s failure to achieve any milestone. If the license granted to Ultragenyx pursuant to Section 2.1(a) is converted to a non-exclusive license for a particular Indication Cluster pursuant to the terms of this Section 3.2, BRI shall promptly provide Ultragenyx with written notice of any Third Party license that BRI grants under the BRI Technology relating to Compounds or Products for such Indication Cluster.

3.3 Regulatory. As between the Parties, Ultragenyx (on its own or acting through or together with any of its Affiliates, sublicensees or contractor manufacturers) has the sole right to: (a) make all Regulatory Filings, submissions, reports, updates and supplements with any Regulatory Authority with respect to any Compound or Product in the Licensed Territory; (b) obtain, hold and maintain all INDs (other than the IND for the BRI Ongoing Study), Regulatory Approvals and Pricing Approvals in the Field in the Licensed Territory in the name of Ultragenyx or any of its Affiliates or sublicensees; and (c) conduct all meeting and discussions and handle all correspondence with any Regulatory Authority related to any Compound or Product in the Licensed Territory. For the BRI Ongoing Study and any additional study that BRI independently conducts pursuant to Section 2.3 (“BRI Independent Studies”): (i) BRI shall promptly provide Ultragenyx with copies of all material documents, information and

correspondence that are received from any Regulatory Authority; (ii) BRI shall provide Ultragenyx with copies of all material documents, information and correspondence that are planned for submission to any Regulatory Authority and BRI shall cooperate with and consider in good faith any input from Ultragenyx in preparing such submission; (iii) BRI shall provide Ultragenyx with reasonable advance notice of all meetings, conferences and discussions scheduled with any Regulatory Authority concerning such study(ies) and BRI shall consider in good faith any input from Ultragenyx in preparing for such meetings, conferences or discussions; and (iv) to the extent permitted by applicable Laws and by any obligations to Third Parties that (A) exist as of the Effective Date or (B) come into existence after the Effective Date, provided that BRI shall use Commercially Reasonable Efforts to obtain such rights for Ultragenyx in its negotiations with Third Parties after the Effective Date, Ultragenyx shall have the right to participate in any such meetings, conferences or discussions and BRI shall facilitate such participation. If either (x) [***] exercises the [***] Option or (y) Ultragenyx does not exercise the Ultragenyx Option, then, in each case, BRI and Ultragenyx shall each use reasonable efforts to facilitate global coordination of clinical data and safety data between Ultragenyx and [***] and/or any other applicable Third Party licensee of BRI in the Retained Territory in order for Ultragenyx, [***] and/or any Third Party licensee to comply with regulatory requirements.

3.4 Pharmacovigilance. If either (a) [***] exercises the [***] Option or (b) Ultragenyx does not exercise the Ultragenyx Option, then, in each case, BRI and Ultragenyx shall use reasonable efforts to facilitate BRI, Ultragenyx and [***] and/or any other applicable Third Party licensee of BRI in the Retained Territory entering into a safety data exchange agreement (“Safety Data Exchange Agreement”) setting forth in detail the pharmacovigilance alert process and data exchange with respect to the Product to comply with all applicable legal obligations of Regulatory Authorities in the Licensed Territory and in the Retained Territory. For the Ongoing Study and any additional study that BRI independently conducts pursuant to Section 2.3, BRI shall cooperate with Ultragenyx and BRI shall transfer all safety data relating to the Product to Ultragenyx pursuant to a procedure to be agreed upon by the Parties; in the event of conversion of the license to non-exclusive, Ultragenyx shall also provide a reciprocal transfer of all its safety data to BRI.

3.5 Manufacture; Provision of Know-How.

(a) Subject to Section 3.5(b), Ultragenyx (on its own or acting through any of its Affiliates, sublicensees or subcontractors) shall be responsible for the manufacture and supply of Compounds and Products in the Licensed Territory for use by Ultragenyx, its Affiliates and sublicensees, at its cost and expense, itself or through one or more contract manufacturers or sublicensees. BRI shall use Commercially Reasonable Efforts to assist Ultragenyx in establishing a direct relationship with BRI’s current supplier of Compounds.

(b) Promptly after the Effective Date, BRI shall provide Ultragenyx with all BRI Know-How that is necessary or reasonably useful to manufacture Compound or Product, including any and all reports and documentation from BRI’s current or former supplier of Compounds that BRI does not have the ability to disclose to Ultragenyx under express or implied obligations of confidentiality.

3.6 Commercialization.

(a) Ultragenyx (on its own or acting through any of its Affiliates, sublicensees or subcontractors) shall book sales for the Products in the Licensed Territory and shall have sole control over pricing and other commercialization decisions with respect to the Products in the Licensed Territory.

(b) As between the Parties, Ultragenyx (on its own or acting through any of its Affiliates, sublicensees or subcontractors) shall have the right to brand commercialized Products using Ultragenyx trademarks and any other trademarks and trade names it determines appropriate for the Products, which may vary by country or within a country (“Product Marks”). Ultragenyx (on its own or acting through any of its Affiliates, sublicensees or subcontractors) shall own all rights in the Product Marks and shall be responsible for registration, maintenance, and defense of the Product Marks at its own costs and expense.

Article 4

(x) [***]	$	[***]

(b) The Parties acknowledge and agree that the milestones set forth in Section 4.2(a)(ii), (vii), (viii), (ix) and (x) above will not be due if such Product triggering the milestone is in an indication that is not covered by a Valid Claim and if Ultragenyx has a financial obligation to pay a milestone pursuant to a Third Party License (as defined in Section 4.4(d) below) on such Product for such indication.

(c) The milestones set forth in Section 4.2(a) shall each be due after the first (1^st) achievement of such milestone for the first Product to achieve such milestone by or on behalf of Ultragenyx or any of its Affiliates or sublicensees, and each such milestone payment shall be payable only once, regardless of how many Products or how many indications for which such milestone has been achieved.

(d) For clarity, the milestones set forth in sub-Section 4.2(a)(i), (ii), (v), (vi), (ix) and (x) above may only be due if Ultragenyx exercises the Ultragenyx Option pursuant to Section 2.2(b).

(e) Ultragenyx shall notify BRI in writing promptly upon each milestone event set forth in this Section 4.2 and BRI shall thereafter submit an invoice to Ultragenyx for the milestone payment corresponding to such milestone event as set forth in this Section 4.2. Ultragenyx shall make such applicable milestone payment within [***] days after receipt of such invoice from BRI.

4.3 Sales Milestone Payments.

(a) Ultragenyx shall pay to BRI the non-refundable, non-creditable sales milestone payments set forth below. The sales milestones shall each be due after the first achievement of such milestone for annual aggregate Net Sales of all Products by or on behalf of Ultragenyx or any of its Affiliates or sublicensees, and each such milestone payment shall be payable only once, regardless of how many Calendar Years during which such sales milestone have been reached.


Sales Milestones	Payments
First (1^st) Calendar Year in which aggregate total Net Sales by Ultragenyx, its Affiliates and sublicensees for all Products throughout the Licensed Territory exceed $[***]		[***]
First (1^st) Calendar Year in which aggregate total Net Sales by Ultragenyx, its Affiliates and sublicensees for all Products throughout the Licensed Territory exceed $[***]	$	[***]

(b) Ultragenyx shall notify BRI in writing within [***] days following the end of the Calendar Year during which any milestone event is achieved and BRI shall thereafter submit an invoice to Ultragenyx for the corresponding milestone payment as set forth in Section 4.4(a). Ultragenyx shall make such applicable milestone payment within [***] days following receipt of such invoice.

4.4 Royalty Payments.

(a) Royalty Rates for Products. Subject to the other terms of this Section 4.4, during the Royalty Term, Ultragenyx shall make quarterly royalty payments to BRI equal to [***] percent ([***]%) of the Net Sales of the Products in the Licensed Territory by Ultragenyx and any of its Affiliates or sublicensees.

(b) Royalty Term. On a Product-by-Product basis and country-by-country basis, Ultragenyx’s royalty payment obligations under this Section 4.4 shall commence upon the First Commercial Sale of such Product in such country and expire upon the later of: (i) the expiration of the period of the first Regulatory Exclusivity granted by the applicable Regulatory Authority applicable to such Product in such country in connection with approval in such country for either FAOD or an Ultra Orphan Indication; or (ii) the expiration of the last-to-expire Valid Claim included in BRI Patents claiming the composition of matter of, or the method of making or using, such Product in such country in connection with approval in such country for FAOD or an Ultra Orphan Indication (“Royalty Term”).

(c) Royalty Reduction for a Product Subject to Generic Competition. For a particular Product in a particular country, during any period during the Royalty Term if one (1) or more Generic Product(s) with respect to such Product is being sold in such country then the applicable royalty rate under this Section 4.4 shall be reduced by [***] percent ([***]%) for such Product in such country.

(d) Royalty Reduction for Third Party Payment Obligations. If Ultragenyx (or any of its Affiliates or sublicensees) enters into any agreement with a Third Party under which Ultragenyx obtains rights under any intellectual property (including any Patent or Know-How) Controlled by a Third Party, which is necessary to the use, development, manufacture, commercialization or import of any Compound or Product (including for the use or commercialization of any Compound or Product in a particular indication) (each, a “Third Party License”), Ultragenyx shall have the right to credit up to [***] percent ([***]%) of the amounts owed by Ultragenyx under any such Third Party License against Ultragenyx’s royalty payments to BRI under this Section 4.4 for the same Product, on a country-by-country basis, provided that, by operation of this Section 4.4(d), Ultragenyx’s royalty payment obligation to BRI shall not be reduced by more than [***] percent ([***]%) for the first such Third Party License or [***] percent ([***]%) for the second and any subsequent such Third Party License(s). For clarity, any applicable royalty reduction pursuant to Section 4.4(c) shall be in addition to any applicable royalty reduction pursuant to this Section 4.4(d) and such royalty reduction is not included within the aforementioned limits.

4.5 Reports; Payment of Royalty; Annual Reconciliation. During the Term, following the First Commercial Sale of a Product and on a Calendar Quarter basis, Ultragenyx shall furnish to BRI a Royalty Report. Reports shall be due within [***] days following the close of each Calendar Quarter. Royalties shown to have accrued by each Royalty Report shall be due and payable on the date such royalty report is due. Ultragenyx shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined.

4.6 Currency; Exchange Rate.

(a) All payments to be made by Ultragenyx to BRI under this Agreement shall be made in Dollars by bank wire transfer in immediately available funds to a bank account designated by written notice from BRI to Ultragenyx. In the case of sales outside the United States, the rate of exchange to be used in computing the monthly amount of currency equivalent in Dollars due BRI shall be made at the monthly rate of exchange published in The Wall Street Journal (U.S., Eastern Edition), prevailing on the last Business Day of the month preceding the month in which such sales are recorded by Ultragenyx.

(b) If pursuant to applicable Law or fiscal policy of a particular country, a remittance of royalties in the currency stipulated in this Section 4.6 is restricted or forbidden, Ultragenyx shall provide notice thereof to BRI, and payment of such royalty shall be made by the deposit thereof in local currency to the credit of BRI in a recognized banking institution designated by BRI or its Affiliates. When in any such country the applicable Law or fiscal policy would then allow the transmittal of such royalty payments, all royalties or other sums that Ultragenyx would have been under obligation to transmit but for the prohibition, shall promptly be transmitted to BRI to the extent allowable.

4.7 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due to such Party from the due date until the date of payment at a per-annum rate of prime plus [***] percentage points or the maximum rate allowable by applicable Law, whichever is less.

4.8 Taxes.

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement.

(b) Tax Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Ultragenyx to BRI under this Agreement. To the extent Ultragenyx is required to deduct and withhold taxes on any payment to BRI, Ultragenyx shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner, and the sum payable to BRI shall be decreased by the same amount. BRI shall provide Ultragenyx any tax forms that may be reasonably necessary in order for Ultragenyx to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. BRI shall use reasonable efforts to provide any such tax forms to Ultragenyx in advance of the due date. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by Law, of withholding taxes or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of BRI as the Party bearing such withholding tax under this Section 4.8(b).

4.9 Records and Audit Rights.

(a) Ultragenyx shall keep complete, true and accurate books and records in relation to this Agreement. Upon the written request of BRI and not more than [***] in each Calendar Year, Ultragenyx shall permit an independent certified public accounting firm selected by BRI, and reasonably acceptable to Ultragenyx, to have access during normal business hours to such of the records of Ultragenyx as may be reasonably necessary to verify the accuracy of the royalty reports hereunder for any Calendar Year ending not more than [***] prior to the date of such request. BRI shall treat all financial information subject to review under this Section 4.9 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement.

(b) Ultragenyx may require an accounting firm conducting an audit hereunder to sign a non-disclosure agreement to protect the confidentiality of Ultragenyx’s Confidential Information before providing such accounting firm access to Ultragenyx’s facilities, books or records. Upon completion of any audit hereunder, the accounting firm shall provide both Ultragenyx and BRI a written report disclosing whether the royalty reports submitted by Ultragenyx are correct or incorrect, whether the amounts paid are correct or incorrect, and in each case, the specific details concerning any discrepancies.

(c) BRI shall bear its internal expenses and the out-of-pocket costs for engaging such accounting firm in connection with performing such audits; provided, however, that if any such audit uncovers an underpayment of milestones payments or royalties by Ultragenyx that exceeds [***] percent ([***]%) of the total owed for such payment or payment period, as applicable, then Ultragenyx shall reimburse BRI for the expenses and costs for such audit.

(d) If such accounting firm identifies an underpayment by Ultragenyx during such period, Ultragenyx shall pay BRI the amount of the discrepancy within [***] days of the date BRI delivers to Ultragenyx such accounting firm’s written report with the amount of underpayment accruing interest at the rate such forth in Section 4.7. If such accounting firm identifies an overpayment by Ultragenyx during such period, Ultragenyx shall, at its option, have the right to request a refund of such overpaid amount, or credit such overpaid amount against subsequent payment obligations to BRI, and BRI shall make such refund to Ultragenyx within [***] days of Ultragenyx’s request if so requested. If Ultragenyx has no future payment obligations under this Agreement, then Ultragenyx may require BRI to refund such overpayment and BRI shall pay such overpaid amount to Ultragenyx within [***] days of Ultragenyx’s request.

Article 5

Intellectual Property Rights

5.1 Patent Prosecution in the Licensed Territory.

(a) As between the Parties, Ultragenyx, acting through outside patent counsel of its choice (“Patent Counsel”), shall have the first right, but not the obligation, to take the lead in the preparation, filing, prosecution and maintenance of the BRI Patents in the Licensed Territory, at Ultragenyx’s cost and expense. BRI shall cooperate with Ultragenyx in filing and prosecution of such BRI Patents in the Licensed Territory, including by providing Ultragenyx with data and other information as appropriate and executing all necessary paperwork. Within [***] days after the Effective Date, BRI shall provide to Ultragenyx those copies of all patent filings, and the correspondence between BRI and patent authorities, for BRI Patents in the Licensed Territory existing as of the Effective Date. Within [***] days after Ultragenyx exercises the Ultragenyx Option pursuant to Section 2.2(a), BRI shall provide Ultragenyx those copies of all patent filings, and the correspondence between BRI and patent authorities, for BRI Patents in the Licensed Territory existing as of the date of exercise of the Ultragenyx Option that have not already been provided to Ultragenyx pursuant to this Section 5.1(a). Ultragenyx will keep BRI reasonably informed of the status of the prosecution of such BRI Patents in the Licensed Territory. For the purpose of this Article 6, “prosecution” shall include any pre-grant and post-grant proceeding including patent interference proceeding, opposition proceeding and other similar proceedings, appeals or petitions to any Board of Appeals in the patent office, appeals to any court for any patent office decisions, reissues and reexamination proceedings, and applications for patent term extensions and the like.

(b) Ultragenyx will notify BRI of any decision not to file for, prosecute or maintain, or not to continue to pay the expenses of prosecution or maintenance of (collectively, “Patent Support”), any BRI Patents in the Licensed Territory. Ultragenyx will provide such notice at least [***] days prior to any filing or payment due date, or any other due date that requires action, in connection with such BRI Patent. In such event, BRI shall have the right, but not the obligation, to file for, or continue prosecution or maintenance of, such BRI Patent in the Licensed Territory, at its expense. In the event BRI does maintain such BRI Patent in the Licensed Territory and such BRI Patent in the Licensed Territory covers the applicable Product that triggers any royalty or milestone payment, Ultragenyx shall continue payment of the applicable royalties and milestones.

5.2 Patent Prosecution in the Retained Territory.

(a) If the Licensed Territory does not expand pursuant to Section 2.2(a), BRI shall use Commercially Reasonable Efforts to prosecute and maintain all of the patents and applications included within the BRI Patents in the Retained Territory. BRI shall: (i) keep Ultragenyx advised of the status of all communications and actual and prospective filings regarding such BRI Patents in the Retained Territory, (ii) give Ultragenyx a reasonable opportunity (but in no event less than [***] business days) to review and comment on any such communications and filings proposed to be sent to any patent authority, and (iii) incorporate all reasonable comments of Ultragenyx before making any such communication or filing related to such BRI Patents in the Retained Territory.

(b) Should BRI (and [***] if the [***] Option has been exercised and [***] has the right) decide that it is no longer interested in maintaining or prosecuting any BRI Patent in the Retained Territory, BRI shall promptly advise Ultragenyx thereof and, upon written notice by Ultragenyx, BRI agrees that Ultragenyx may prosecute and maintain such BRI Patent in its own name, and BRI shall execute all required documents in order to assign any such BRI Patent to Ultragenyx; provided, however, that any such assignment by BRI shall be subject to the [***] Option.

5.3 Patent Enforcement and Defense in the Licensed Territory.

(a) Each Party shall give the other Party written notice of any infringement by a Third Party of any BRI Patents through the development or commercialization of a Product in the Field in the Licensed Territory (a “Licensed Territory Product Infringement”), within [***] Business Days after such Licensed Territory Product Infringement comes to such Party’s attention.

(b) Ultragenyx shall have the sole and exclusive right, but not the obligation, to bring and control any legal action in connection with such Licensed Territory Product Infringement in the Licensed Territory at its own expense and discretion as it reasonably determines appropriate. BRI shall have the right to be represented in any such action by counsel of its choice at its own expense. Should Ultragenyx decline to bring a legal action in connection with a Licensed Territory Product Infringement in the Licensed Territory, BRI shall have the right, but not the obligation, to bring such a legal action. In the event that the Licensed Territory Product Infringement involves a Generic Product, and Ultragenyx declines to bring a legal action, Ultragenyx shall not be permitted to reduce royalties due BRI pursuant to Section 4.4(c). For clarity, Ultragenyx’s right to bring and control any legal action under this Section 5.3(b)shall not apply to a Licensed Territory Product Infringement in an Indication Cluster during the period of time in which Ultragenyx has anon-exclusive license.

(c) At the request of a party bringing a legal action under Section 5.2(b) (the “Litigating Party”), the other Party shall reasonably cooperate and provide any information or assistance in connection with any legal action under this Section 5.3, including executing reasonably appropriate documents, cooperating in discovery and joining as a party to the action if required, all at the Litigating Party’s expense.

(d) Any recoveries resulting from such an action relating to a claim of Licensed Territory Product Infringement shall be first applied against payment of costs and expenses in connection with the action of the Party which initiated and prosecuted the action. The other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action. Solely in the case in which Ultragenyx is the Litigating Party, any such recoveries in excess of such costs and expenses of the Parties shall be retained by Ultragenyx and shall be deemed Net Sales subject to Ultragenyx’s royalty payment obligation to BRI under Section 4.4. In the event BRI is the Litigating Party, all recoveries in excess of such costs and expenses of the Parties shall be retained by BRI.

5.4 Patent Enforcement and Defense in the Retained Territory.

(a) If the Licensed Territory does not expand pursuant to Section 2.2(a), each Party shall give the other Party written notice of any infringement by a Third Party of any BRI Patents through the development or commercialization of a Product in the Field in the Retained Territory (a “Retained Territory Product Infringement”), within [***] Business Days after such Retained Territory Product Infringement comes to such Party’s attention.

(b) As between the Parties, BRI shall have the right, but not the obligation, to bring and control any legal action in connection with such Retained Territory Product Infringement in the Retained Territory at its own expense. BRI shall, if it has brought or controls such legal action, use Commercially Reasonable Efforts to: (i) keep Ultragenyx advised of the status of all such legal actions, (ii) give Ultragenyx a reasonable opportunity to review and comment on any filings, motions, pleadings or other strategic decisions relating to such legal action, and (iii) incorporate all reasonable comments of Ultragenyx in conducting such legal action, and, in each case, BRI shall use Commercially Reasonable Efforts to require [***] or any other applicable Third Party licensee of BRI in the Retained Territory to do so.

5.5 Third Party Patent Proceedings. Each Party will notify the other Party in writing prior to challenging any Patents controlled by a Third Party that are necessary or reasonably useful to use, develop, manufacture, commercialize or import any Compound or Product. Such challenges include declaratory judgment actions, inter parties re-examinations, interferences, oppositions and other similar proceedings (collectively “Third Party Patent Proceeding”).

(a) Except as the Parties otherwise agree, Ultragenyx shall have the first right to bring and control any legal action in connection with such Third Party Patent Proceeding in the Field in the Licensed Territory, at its own expense and discretion as it reasonably determines appropriate.

(b) At the request of Ultragenyx, BRI shall reasonably cooperate and provide any information or assistance in connection with any legal action under this Section 5.3, including executing reasonably appropriate documents, cooperating in discovery and joining as a party to the action if required, all at Ultragenyx’s expense. Ultragenyx shall keep BRI reasonably informed of the status of such action.

5.6 Patent Extensions. The Parties shall cooperate in obtaining patent term restoration (under but not limited to Drug Price Competition and Patent Term Restoration Act), supplemental protection certificates or their equivalents, and patent term extensions with respect to the BRI Patents in any country or region in the Licensed Territory where applicable, provided, that Ultragenyx shall have the final decision making authority on the foregoing.

Article 6

Confidentiality; Publication

6.1 Duty of Confidence. Subject to the other provisions of this Article 6:

(a) all Confidential Information disclosed by or on behalf of a Party or its Affiliates (“Disclosing Party”) under this Agreement, or in the course of contemplating a transaction under this Agreement prior to the execution of this Agreement, shall be maintained in confidence and otherwise safeguarded by the recipient Party and its Affiliates (“Receiving Party”), in the same manner and with the same protection as such Receiving Party maintains its own confidential information, but at least with reasonable protection;

(b) the Receiving Party may only use any such Confidential Information for the purposes of performing its obligations or exercising its rights under this Agreement; and

(c) the Receiving Party may disclose Confidential Information of the other Party to: (i) its Affiliates and sublicensees; and (ii) employees, directors, agents, contractors, consultants and advisers of the Party and its Affiliates, licensees and sublicensees, in each case to the extent reasonably necessary for the purposes of, and for those matters undertaken pursuant to, this Agreement; provided that such Persons are bound to maintain the confidentiality of the Confidential Information in a manner consistent with the confidentiality provisions of this Agreement. Notwithstanding the foregoing, the Parties acknowledge and agree that BRI may not disclose any Confidential Information of Ultragenyx to [***] or any other licensee or sublicensee of the Compound and/or Product in the Option Territory without Ultragenyx’s prior written consent. Ultragenyx acknowledges that, pursuant to the [***] Option as amended on February 22, 2012, BRI is required to disclose preclinical and clinical data and information regarding regulatory submissions in the Licensed Territories to [***], and with respect to BRI Independent Studies, shall require no consent from Ultragenyx to do so.

6.2 Exceptions. The foregoing obligations as to particular Confidential Information of a Disclosing Party shall not apply to the extent that the Receiving Party can demonstrate that such Confidential Information:

(a) was known by the Receiving Party at the time of its receipt, and not through a prior disclosure by the Disclosing Party, as documented by the Receiving Party’s written records;

(b) was in the public domain before its receipt from the Disclosing Party, or thereafter enters the public domain through no fault of the Receiving Party;

(d) is developed by the Receiving Party independently and without use of or reference to any Confidential Information received from the Disclosing Party, as documented by the Receiving Party’s written records.

Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the Receiving Party unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the Receiving Party.

6.3 Authorized Disclosures. Notwithstanding the obligations set forth in Sections 6.2 and 6.5, a Party may disclose the other Party’s Confidential Information (including this Agreement and the terms herein) solely to the extent:

(a) such disclosure: (i) is reasonably necessary for the filing or prosecuting Patents as contemplated by this Agreement; (ii) is reasonably necessary in connection with Regulatory Filings for Products; (iii) is reasonably necessary for the prosecuting or defending of legal actions, including litigation, as contemplated by this Agreement; or (iv) is made to any Third Party bound by written obligation of confidentiality and non-use similar to those set forth under this Article 6, to the extent otherwise necessary or appropriate in connection with the exercise of its rights or the performance of its obligations hereunder;

(b) such disclosure is reasonably necessary: (i) to such Party’s directors, attorneys, independent accountants or financial advisors for the sole purpose of enabling such directors, attorneys, independent accountants or financial advisors to provide advice to the Receiving Party, provided that in each such case on the condition that such directors, attorneys, independent accountants and financial advisors are bound by confidentiality and non-use obligations substantially consistent with those contained in this Agreement; provided, however, that the term of confidentiality for such directors, attorneys, independent accountants and financial advisors shall be no less than [***]; or (ii) to actual or potential investors, sublicensees or acquirors solely for the purpose of evaluating an actual or potential investment, sublicense or acquisition; provided that in each such case on the condition that such actual or potential investors, sublicensees and acquirers are bound by confidentiality and non-use obligations substantially consistent with those contained in this Agreement; provided, however, that the term of confidentiality for such actual or potential investors and acquirers shall be no less than [***]; or

(c) such disclosure is required by judicial or administrative process, provided that in such event such Party shall promptly inform the other Party of such required disclosure and provide the other Party an opportunity to challenge or limit the disclosure obligations. Confidential Information that is disclosed by judicial or administrative process shall remain otherwise subject to the confidentiality and non-use provisions of this Article 7, and the Party disclosing Confidential Information pursuant to law or court order shall take all steps reasonably necessary, including seeking of confidential treatment or a protective order to ensure the continued confidential treatment of such Confidential Information.

6.4 Scientific Publications. Subject to Section 6.3, Ultragenyx or its sublicensee(s) shall have the sole right to make any public publication or presentation of any data regarding any Compound or Product, provided, however, that to the extent such data arises as a result of work performed by a BRI employee or contractor, or with financial support by BRI, BRI shall be provided with a copy of any proposed publication at least [***] days prior to submission for BRI’s review and comment, and as appropriate in accordance with scientific journal standards, shall designate the appropriate BRI personnel as co-authors. However, such publication or presentation shall not include any Confidential Information of BRI without the prior written consent of BRI. Subject to Section 6.3, BRI shall make no public publication or presentation of any data regarding any Compound or Product without the prior written consent of Ultragenyx. Notwithstanding the foregoing, this Section 6.4 shall not apply to any publication or presentation of data relating to BRI Know-How or BRI Patents existing as of the Effective Date, provided that BRI shall provide Ultragenyx with a copy of any proposed publication or presentation at least [***] days prior to submission, for Ultragenyx’s review and comment.

6.5 Publicity; Use of Names. Notwithstanding anything to the contrary in this Agreement, until the expiration of the [***] Option and Ultragenyx’s receipt of the Ultragenyx Option Notice, the existence and the terms of this Agreement are each Party’s Confidential Information and such shall be held in strict confidence and not disclosed by either Party, except with the prior express written permission of the other Party or as may be required by applicable Law. Subject to Sections 6.1, 6.2 and 6.3, no other disclosure of the existence or the terms of this Agreement may be made by either Party or its Affiliates except as provided in this Section 6.5, and no Party shall use the name, trademark, trade name or logo of the other Party, its Affiliates or their respective employees in any publicity, promotion, news release or disclosure relating to this Agreement or its subject matter, except as provided in this Section 6.5 or with the prior express written permission of the other Party, except as may be required by applicable Law.

(a) A Party may disclose this Agreement and its terms, and material developments or material information generated under this Agreement, in securities filings with the US Securities and Exchange Commission (or equivalent foreign agency) to the extent required by applicable Law after complying with the procedure set forth in this Section 6.5(a). In such event, the Party seeking such disclosure will prepare a draft confidential treatment request and proposed redacted version of this Agreement to request confidential treatment for this Agreement, and the other Party agrees to promptly (and in any event, no more than seven (7) days after receipt of such confidential treatment request and proposed redactions) give its input in a reasonable manner in order to allow the Party seeking disclosure to file its request within the time lines proscribed by applicable Law.

Article 7

Term and Termination

7.1 Term. The term of this Agreement will commence upon the Effective Date and continue in full force and effect, on a Product-by-Product and country-country basis, until the expiration of the royalty obligations of Ultragenyx with respect to the applicable Product, unless earlier terminated as set forth in Section 7.2 (the “Term”). After the expiration of this Agreement for a particular Product in a particular country, Ultragenyx’s license in such country shall become fully paid, royalty-free, perpetual and irrevocable.

7.2 Termination.

(a) Termination by Ultragenyx for Convenience. At any time, Ultragenyx may terminate this Agreement, in its entirety or on a Product-by-Product basis, by providing written notice of termination to BRI, which notice includes an effective date of termination at least ninety (90) days after the date of the notice.

(b) Termination for Material Breach. If either Party believes that the other is in breach of its material obligations hereunder (other than Ultragenyx’s nonfulfillment of its obligations under Section 3.2, the remedy of which is set forth in Section 3.2), then the non-breaching Party may deliver notice of such breach to the other Party. The allegedly breaching Party shall have ninety (90) days from such notice to dispute or cure such breach. If the Party receiving notice of breach fails to cure, or fails to dispute, that breach within the period set forth above, then the Party originally delivering the notice of breach may terminate this Agreement effective on written notice of termination to the other Party, provided that such non-breaching Party delivers such notice of termination within sixty (60) days of the end of such one hundred ninety(90)-day cure period. If the allegedly breaching Party in good faith disputes such material breach or disputes the failure to cure or remedy such material breach and provides written notice of that dispute to the other Party within the period set forth above, the notifying Party may not terminate this Agreement until one independent industry expert mutually agreeable to both Parties has determined that the allegedly breaching Party is in material breach of this Agreement, and such breaching Party further fails to cure such breach within thirty (30) days after such determination by the independent industry expert (and such termination shall then be effective upon written notification from the notifying Party to the breaching Party).

(c) Termination for Bankruptcy. Either party may terminate this Agreement in the event the other Party ceases doing business as a going concern, makes an assignment for the benefit of creditors, shall not be paying its debts in the ordinary course, shall have become insolvent or shall, voluntarily or involuntarily, become party to insolvency proceeding, or commits any act of bankruptcy. Notwithstanding any other provision of this Agreement to the contrary, in the event that BRI becomes a debtor under the United States Bankruptcy Code (11 U.S.C. §101 et. seq. or any similar law in any other country (the “Bankruptcy Code”)) and rejects this Agreement pursuant to Section 365 of the Bankruptcy Code (a “Bankruptcy Rejection”), (i) the license to the BRI Technology described under this Agreement shall be deemed fully retained by and vested in Ultragenyx as protected intellectual property rights under Section 365(n)(1)(B) of the Bankruptcy Code and further shall be deemed to exist immediately before the commencement of the bankruptcy case in which BRI is the debtor; and (ii) Ultragenyx shall have all of the rights afforded to non-debtor licensees under Section 365(n) of the Bankruptcy Code, subject to its continued compliance with all its obligations under this Agreement. All rights and licenses now or hereinafter granted by BRI to Ultragenyx under or pursuant to any section of this Agreement, including Section 2.1 are rights to “intellectual property” (as defined in the Bankruptcy Code).

7.3 Effect of Termination.

(a) Termination by Ultragenyx for Convenience; Termination by BRI for Breach or Bankruptcy. Upon termination of this Agreement by Ultragenyx pursuant to Section 7.2(a) or by BRI pursuant to Sections 7.2(b) or 7.2(c), the following consequences shall apply to the termination and shall be effective as of the effective date of such termination:

(i) Each Party shall pay all amounts then due and owing to the other Party as of the termination date;

(ii) All licenses and other rights granted to Ultragenyx under the BRI Technology will terminate, and Ultragenyx shall immediately discontinue sales of Product;

(iii) No later than thirty (30) days after the effective date of such termination, Ultragenyx shall return or cause to be returned to BRI all Confidential Information in tangible form received from BRI and all copies thereof and all materials substances or compositions delivered or provided by BRI; provided, however, that Ultragenyx may keep one copy of Confidential Information received from the other Party in its confidential files for record purposes;

(iv) No later than thirty (30) days after the effective date of termination, at BRI’s option, the Parties shall negotiate in good faith the terms and conditions (including financial compensation to Ultragenyx) for a license under patent applications, patents, Know-How, and any other information and documentation Controlled by Ultragenyx as of the effective date of such termination necessary for BRI to continue development and commercialization of Products in the Licensed Territory, but solely for those indications, the use of which are claimed by a Valid Claim in the BRI Technology as of the date of such termination. If the Parties have failed to agree upon such terms of compensation within ninety (90) days of initiation of such negotiation, the matter shall be referred to three independent industry experts having expertise in intellectual property valuation and who are mutually agreeable to both Parties. The industry experts shall take into account all pertinent factors, including but not limited to each party’s relative contribution to the Ultragenyx Technology, and within thirty (30) days make a joint recommendation of appropriate compensation for the license (“License Compensation”). BRI shall have the right, but not the obligation, to accept the license at the recommended License Compensation. If BRI does not accept the license at the recommended License Compensation, then Ultragenyx shall have no further obligation to negotiate with BRI regarding the terms and conditions for a license pursuant to this Section 7.3(a)(iv) and Ultragenyx shall have no obligation to grant BRI any such license. If BRI does accept the license at the recommended License Compensation, then Ultragenyx shall have the obligation to grant BRI the license at the recommended License Compensation; and

(v) At the written request of any of Ultragenyx’s sublicensees under this Agreement, BRI shall negotiate in good faith with such sublicensee an agreement between BRI and such sublicensee under which such sublicensee will obtain a direct license under the BRI Technology. For clarity, under no circumstances shall BRI be required to grant a direct license to any sublicensee which does not compensate BRI at a level substantially equivalent to the compensation received by BRI under this Agreement with respect to the applicable technology, taking into consideration any costs associated with BRI’s license to Ultragenyx Technology. Ultragenyx shall indemnify, defend and hold BRI Indemnitees harmless from and against any Claims brought by any sublicensee in connection with the termination of an Ultragenyx sublicense, or the inability of BRI and any sublicensee to negotiate a mutually

acceptable license to BRI Technology, provided that Ultragenyx shall have no indemnification obligation to BRI under this Section 7.3(a)(v) to the extent such Claim arises as a result of BRI’s bad faith in negotiation with an Ultragenyx sublicensee.

(b) Termination by Ultragenyx for Breach or Bankruptcy. Upon termination of this Agreement by Ultragenyx pursuant to Sections 7.2(b) or 7.2(c), the following consequences shall apply to the termination and shall be effective as of the effective date of such termination:

(i) Each Party shall pay all amounts then due and owing to the other Party as of the termination date;

(ii) The licenses and other rights granted by BRI to Ultragenyx under the BRI Technology will remain in full force and effect as set forth in Sections 2.1; provided that Ultragenyx fulfills its payment obligations to BRI under Article 4 pursuant to the terms and conditions set forth in Article 4, further provided that, on a Product-by-Product and country by country basis, for any Product that is the subject of the underlying breach, milestone payments under Sections 4.2 and 4.3 and royalty payments under Section 4.4 with respect to such Product shall be reduced by [***] percent ([***]%);

(iii) No later than thirty (30) days after the effective date of such termination, BRI shall return or cause to be returned to Ultragenyx all Confidential Information in tangible form received from Ultragenyx and all copies thereof and all materials, substances or compositions delivered or provided by Ultragenyx; provided, however, that BRI may keep one copy of Confidential Information received from Ultragenyx in its confidential files for record purposes; and

(iv) In addition to the provisions set forth in Section 7.5, the provisions relating to BRI Patents in Sections 6.1, 6.2, 6.3 and 6.4 shall survive the termination of this Agreement for so long as the license to Ultragenyx survives under this Section 7.3(b).

7.4 Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. Without limiting the foregoing, the provisions of Articles 1, 6, 9 (to the extent the Claims arise out of actions or omissions during the Term) and 10, and Sections 5.1, 7.3, 7.4 and 7.5, and any other provisions which by their nature are intended to survive, shall survive the expiration or termination of this Agreement.

7.5 Termination Not Sole Remedy. Termination is not the sole remedy under this Agreement and, whether or not termination is effected and notwithstanding anything contained in this Agreement to the contrary, all other remedies will remain available except as agreed to otherwise herein.

Article 10

General Provisions

10.1 Force Majeure.

10.3 Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties.
