Such records shall be subject to inspection in accordance with Section 7.5.

Such inspections may be made no more than once each Fiscal Year (unless an audit or inspection reveals a material inaccuracy in reports made under this Agreement, in which case it may be repeated within such Fiscal Year), and during normal business hours, with reasonable efforts to minimize disruption of Distributor's normal business activities. Inspections conducted under this Section 7.5 shall be at the expense of Zogenix, unless a variation or error producing an underpayment in amounts payable exceeding [***] of the amount paid for a period covered by the inspection is established, in which case all reasonable costs relating to the inspection for such period shall be paid by Distributor.

The payment of such interest shall not limit a Party from exercising any other rights it may have as a consequence of the lateness of any payment.

ARTICLE 8. CONFIDENTIALITY

8.1 Confidential Information.

Confidential Information of the other Party. Each Party will promptly notify the other upon discovery of any unauthorized use or disclosure of the Confidential Information of the other Party.

(e) disclosure to its and its Affiliates' contractors, employees and consultants, in each case who need to know such information for filing for, obtaining and maintaining Regulatory Approvals and Commercialization of Product in the Territory in accordance with this Agreement and manufacturing and supplying of Product in accordance with the Supply Agreement (or, in the case of disclosures by Zogenix, who need to know such information for the Development, manufacture and commercialization of the Product outside the Field or Territory), on the condition that any such Third Parties agree to be bound by confidentiality and non-use obligations that are no less stringent than those confidentiality and non-use provisions contained in this Agreement; and

bound by confidentiality and non-use obligations that are no less stringent than those confidentiality and non-use provisions contained in this Agreement.

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party's Confidential Information pursuant to Section 8.3(b) or (c), it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use efforts to secure confidential treatment of such information at least as diligent as such Party would use to protect its own confidential information, but in no event less than reasonable efforts. In any event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder.

8.4 Confidentiality of this Agreement and its Terms. Except as otherwise provided in this Article 8, each Party agrees not to disclose to any Third Party the existence of this Agreement or the terms of this Agreement without the prior written consent of the other Party, except that each Party may disclose the terms of this Agreement that are not otherwise made public as contemplated by Section 8.5 as permitted under Section 8.3.

8.5 Public Announcements.

(a) As soon as practicable following the Effective Date, the Parties may each issue a press release in English and/or Japanese, in the form attached hereto as Exhibit 8.5(a), announcing the existence of this Agreement. Except as required by Applicable Laws (including disclosure requirements of the SEC or any stock exchange on which securities issued by a Party or its Affiliates are traded), neither Party shall make any other public announcement concerning this Agreement or the subject matter hereof without the prior written consent of the other, which shall not be unreasonably withheld or delayed; provided that each Party may make any public statement in response to questions by the press, analysts, investors or those attending industry conferences or financial analyst calls, or issue press releases, so long as any such public statement or press release is not inconsistent with prior public disclosures or public statements approved by the other Party pursuant to this Section 8.5 and does not reveal non‑public information about the other Party; and provided further that Zogenix may make public statements regarding the results of Development and Commercialization activities in the Territory. In the event of a public announcement required by Applicable Laws, to the extent practicable under the circumstances, the Party making such announcement shall provide the other Party with a copy of the proposed text of such announcement sufficiently in advance of the scheduled release to afford such other Party a reasonable opportunity to review and comment upon the proposed text.

(b) The Parties will coordinate in advance with each other in connection with the filing of this Agreement (including redaction of certain provisions of this Agreement) with the SEC or any stock exchange on which securities issued by a Party or its Affiliate are traded, and each Party will use reasonable efforts to seek confidential treatment for the terms proposed to be redacted; provided that each Party will ultimately retain control over what information to disclose to the SEC or other applicable government body, and provided further that the Parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent with redacted versions previously filed with any other governing bodies. Other than

31

US-DOCS\105216871.19

Source: ZOGENIX, INC., 10-Q, 5/9/2019





such obligation, neither Party (nor its Affiliates) will be obligated to consult with or obtain approval from the other Party with respect to any filings to the SEC or any other government body governing a stock exchange.

(c) Except as expressly permitted in this Agreement or as required by Applicable Laws, neither Party may use the other Party's trademarks, service marks or trade names, or otherwise refer to or identify that other Party in marketing or promotional materials, press releases, statements to news media or other public announcements, without the other Party's prior written consent, which that other Party may grant or withhold in its sole discretion.

8.6 Publication. At least [***] prior to Distributor or its Affiliates or Sub-distributors publishing, publicly presenting, and/or submitting for written or oral publication a manuscript, presentation, abstract, marketing document or the like that includes Information relating to the Product that has not been previously published, Distributor shall provide to Zogenix's Alliance Manager a draft copy thereof for Zogenix's review (unless Distributor is required by Applicable Laws to publish such Information sooner, in which case Distributor shall provide such draft copy to Zogenix's Alliance Manager as much in advance of such publication as possible). Distributor shall consider in good faith any comments provided by Zogenix during such [***] period, and in the event that Zogenix raises any concerns the matter shall be raised at the JSC; provided that Distributor shall, at Zogenix's reasonable request, cease such proposed publication or remove therefrom any information requested by Zogenix. The contribution of each Party shall be noted in all publications or presentations by acknowledgment or co-authorship, whichever is appropriate.

8.7 Prior Non-Disclosure Agreements. As of the Effective Date, the terms of this Article 8 shall supersede any prior non-disclosure, secrecy or confidentiality agreement between the Parties (or their Affiliates) dealing with the subject of this Agreement, including the Confidentiality Agreement, but excluding any terms of the Supply Agreement. Any information disclosed under such prior agreements shall be deemed disclosed under this Agreement.

8.8 Equitable Relief. Given the nature and value of the Confidential Information and the competitive damage and irreparable harm that would result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 8. If the Receiving Party becomes aware of any breach or threatened breach of this Article 8 by the Receiving Party or a Third Party to whom the Receiving Party disclosed the Disclosing Party's Confidential Information, the Receiving Party promptly shall notify the Disclosing Party and cooperate with the Disclosing Party to regain possession of its Confidential Information and prevent any further breach. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 8 without furnishing proof of actual damages or posting a bond.

(i) Change of Control. This Agreement may be terminated by either Party upon [***] written notice to the other Party in the event that the other Party undergoes a Change of Control; provided, however, that such termination notice shall only be effective if delivered within [***] after the later of the occurrence of such Change of Control or the date the Party undergoing the Change of Control delivers written notice thereof to the other Party.

deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement (other than failure to make payment when due) when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, including embargoes, war, acts of war (whether war be declared or not), insurrections, riots, fire, floods, or other acts of God, or acts, omissions or delays in acting by any governmental authority or the other Party.

This Agreement shall be binding upon successors and permitted assigns of the Parties. Any assignment not in accordance with this Section 14.3 will be null and void.

14.4 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. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.
