5.7Tax.

(a)Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income, including any payments received, as contemplated in 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 any payments made by a Party to the other Party under this Agreement. The Parties acknowledge that 3DAlpha does not intend to engage in any reorganization or transfer any payment obligations that it has to Tracon in a transaction that would, solely due to any such action by 3DAlpha after the Effective Date, result in additional withholding taxes on any payments that may become due to Tracon under this Agreement. However, in the event of any such transaction that does result in any additional withholding taxes, the liability for such withholding taxes shall be the sole responsibility of 3DAlpha and such payment obligations shall be increased so that Tracon receives the full amount it would have received had no such additional withholding taxes been withheld.

(c)Payment of Tax. To the extent a Party is required by Applicable Laws to deduct and withhold taxes on any payment to the other Party, the paying Party shall pay the amounts of such taxes to the proper tax authority in a timely manner and promptly transmit to the other Party an official tax certificate or other evidence of such withholding sufficient to enable such other Party to claim such payment of taxes.

Tracon hereby agrees to defend, hold harmless and indemnify each of 3DAlpha, its Affiliates and their agents, shareholders, directors, officers, employees and consultants and successors and assigns of any of the foregoing (the “3DAlpha Indemnitees”) from and against any and all liabilities, expenses and losses, including reasonable legal expenses and attorneys’ fees (collectively “Losses”), incurred by any 3DAlpha Indemnitee as a result of any suits, claims, actions and demands brought by a Third Party (each, a “Third Party Claim”) arising directly or indirectly out of (a) any breach of any representations, warranties, covenants or agreements by Tracon under this Agreement, or (b) the negligence or willful misconduct of any Tracon Indemnitee, or (c) the research, development, manufacture, use, handling, storage, sale or other disposition of the Collaborative Product by Tracon or its Affiliates, licensees or sublicensees.

7.2Indemnification by 3DAlpha. 3DAlpha hereby agrees to defend, hold harmless and indemnify Tracon, its Affiliates and their agents, directors, officers, employees and consultants and successors and assigns of any of the foregoing (the “Tracon Indemnitees”) from and against any and all Losses incurred by any Tracon Indemnitee as a result of any Third Party Claims arising directly or indirectly out of (a) any breach of any representations, warranties, covenants or agreements by 3DAlpha under this Agreement, (b) the negligence or willful misconduct of 3DAlpha Indemnitees, or (c) the research, development, manufacture, use, handling, storage, sale or other disposition of the Collaborative Product by 3DAlpha or its Affiliates, licensees or sublicensees. 3DAlpha’s obligation to indemnify the Tracon Indemnitees pursuant to the foregoing sentence shall not apply to the extent that any such Losses arise from any activities set forth in Section 7.1, for which Tracon is obligated to indemnify 3DAlpha Indemnitees under Section 7.1.

7.3Procedure. The indemnified Party shall provide the indemnifying Party with prompt notice of the claim giving rise to the indemnification obligation pursuant to this Article 7 and the exclusive ability to defend (with the reasonable cooperation of the indemnified Party) or settle any such claim; provided, however, that the indemnifying Party shall not enter into any settlement for damages other than monetary damages without the indemnified Party’s written consent, such consent not to be unreasonably withheld. The indemnified Party shall have the right to participate, at its own expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the indemnifying Party. If the Parties cannot agree as to the application of Sections 7.1 and 7.2 to any particular Third Party Claim, the Parties may conduct separate defenses of such Third Party Claim. Each Party reserves the right to claim indemnity from the other in accordance with Sections 7.1 and 7.2 above upon resolution of the underlying claim, notwithstanding the provisions of this Section 7.3 requiring the indemnified Party to tender to the indemnifying Party the exclusive ability to defend such claim or suit. The failure to deliver written notice to the indemnifying Party within a reasonable time after the commencement of any action with respect to a Third Party Claim shall only relieve the indemnifying Party of its indemnification obligations under this Article 7 if and to the extent the indemnifying Party is actually prejudiced thereby.

7.4Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES OR LOSS OF PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

Article 8
Confidentiality

8.1Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, each Party (in such capacity, the “Receiving Party”) agrees that, for the Term and for a period of ten (10) years thereafter, it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder) any Confidential Information of the other Party (in such capacity, the “Disclosing Party”). Pursuant to Section 9.1, Development Data should be deemed as Confidential Information of 3DAlpha. The Receiving Party shall use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but in no event less than reasonable care) to ensure that its, and its Affiliates’, employees, directors, officers, agents, consultants, advisors (including legal, accounting, or other professional advisors) and other representatives (collectively the “Representatives”) do not disclose or make any unauthorized use of the Confidential Information. The Receiving Party may disclose Confidential Information only to the Representatives on a need-to-know basis. The Receiving Party will have executed or shall execute appropriate written agreements with its Representatives sufficient to enable it to comply with all the provisions of this Agreement, or the Representatives shall be bound by written confidentiality obligations no less stringent as those obligations imposed on the Receiving Party under this Agreement, and Receiving Party shall be responsible for the acts and or omissions of such Representative with regards to or any breach of the confidentiality obligations herein by such Representatives. The Receiving Party shall promptly notify the Disclosing Party upon discovery of any unauthorized use or disclosure of the Disclosing Party’s Confidential Information and will cooperate with Disclosing Party in every reasonable way to help Disclosing Party regain possession of the Confidential Information and prevent its further unauthorized use or disclosure. The foregoing confidentiality and non-use obligations shall not apply to any portion of the Confidential Information that the Receiving Party can demonstrate by competent written proof:

(a)was already known to the Receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the Disclosing Party;

(b)was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party;

(c)became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the Receiving Party in breach of this Agreement;

(d)is subsequently disclosed to the Receiving Party by a Third Party who has a legal right to make such disclosure; or

31.

Execution Copy

Confidential

(e)is subsequently independently discovered or developed by the Receiving Party without the aid, application, or use of the Disclosing Party’s Confidential Information, as evidenced by a contemporaneous writing.

8.2Authorized Disclosure. Notwithstanding the obligations set forth in Section 8.1, the Receiving Party may disclose the Disclosing Party’s Confidential Information and the terms of this Agreement to the extent:

(a)such disclosure is reasonably necessary for (i) the Development, manufacture or Commercialization of the Collaborative Product, including obtaining and maintaining Regulatory Approval or patent protection, pursuant to the terms of this Agreement; or (ii) the prosecuting or defending litigation as contemplated by this Agreement; or

(b)such disclosure is reasonably necessary: (i) to the Receiving 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 in writing by confidentiality and non-use obligations consistent with those contained in this Agreement; or (ii) to actual or potential investors, acquirers, licensors, licensees, collaborators or other business partners solely for the purpose of evaluating or carrying out an actual or potential investment, acquisition, license or collaboration; provided that in each such case on the condition that such disclosures are bound in writing by confidentiality and non-use obligations consistent with those contained in the Agreement;

(c)such disclosure is required by Applicable Laws, including judicial or administrative process. Confidential Information that is disclosed under this Section 8.2(c) shall remain otherwise subject to the confidentiality and non-use provisions of this Article 8, and the Party disclosing Confidential Information pursuant to Applicable Laws may disclose, but only to the extent so required, and 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.

(d)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(a)(ii) or Section 8(c), it will, except where impracticable, give reasonable advance written notice to the other Party of such disclosure to allow the other Party a reasonable opportunity to seek a protective order or equivalent 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. Any such disclosure, however, shall not relieve the such Party of its obligations as the Receiving Party contained herein.

8.3Public Announcements.

Confidential

(a)Publicity. Subject to the rest of this Section 8, no Party shall use the name, trademark, trade name or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or disclosure relating to this Agreement or its subject matter, without the prior express written permission of the other Party, except as may be required by Applicable Laws.

(b)Press Releases. As soon as practicable following the Effective Date, the Parties shall issue a joint press release announcing the execution of this Agreement in substantially the form attached hereto as Exhibit C. Except as required by applicable securities laws (including disclosure requirements of the U.S. Securities and Exchange Commission (“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 and which do not reveal non‑public information about the other Party. In the event of a required public announcement, 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.

(c)Filing of this Agreement. The Parties shall 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 or governmental agency 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 any stock exchange or other governmental agency, as the case may be, 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 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 stock exchange or other governmental agency.

8.4Publication. At least seven (7) days prior to a Party or of any of its Affiliates, or Licensees in the case of 3DAlpha, publishing, publicly presenting, and/or submitting for written or oral publication a manuscript, abstract or the like that includes Know-How relating to the Collaborative Product that has not been previously published, such Party shall provide to the other Party a draft copy thereof for its review (unless such Party is required by law to publish such Know-How sooner, in which case such Party shall provide such draft copy to the other Party as much in advance of such publication as possible). The publishing Party shall consider in good faith any comments provided by the other Party during such seven (7) day period. The review

By mutual agreement of the Parties, this period may be further extended. In addition, the publishing Party shall, and shall cause its Affiliates and Licensees, as applicable, at the other Party’s reasonable request, remove therefrom any Confidential Information of such other Party. The contribution of each Party shall be noted in all publications or presentations by acknowledgment or co-authorship, whichever is appropriate.

8.5Prior Non-Disclosure Agreement. As of the Effective Date, the terms of this Section 8 shall supersede any prior non-disclosure, secrecy or confidentiality agreement between the Parties (or their Affiliates) dealing with the subject of this Agreement. Any information disclosed pursuant to any such prior agreement shall be deemed Confidential Information for purposes of this Agreement.

8.6Equitable Relief. Each Party acknowledges that a breach of this Section 8 cannot be reasonably or adequately compensated in damages in an action at law and that such a breach shall cause the other Party irreparable injury and damage. By reason thereof, each Party agrees that the other Party shall be entitled, in addition to any other remedies it may have under this Agreement or otherwise, to preliminary and permanent injunctive and other equitable relief to prevent or curtail any breach of the obligations relating to Confidential Information set forth herein.

(a)As part of the Collaborative Products License, 3DAlpha hereby grants a non-exclusive, nontransferable license to Tracon under the Collaborative Product IP and Development IP for the conduct of clinical trials in the European Union in support of the Development of Collaborative Products in the Field in the Collaborative Territory. For clarity, the Collaborative Products License shall not include the right to Commercialize or seek Regulatory Approval of Collaborative Products outside of the Collaborative Territory and the Field.

(b)The Collaborative Products License shall not be sublicensable by Tracon except with the written consent of 3DAlpha.

(c)Notwithstanding the foregoing grant of the Collaborative Products License and subject to the other terms of this Agreement, 3DAlpha expressly reserves the right to grant Licenses to Third Parties in the Collaborative Product IP and Development IP outside the Collaborative Territory.

(d)If the Parties mutually agree in writing to stop Development of Collaborative Product, or after a Tracon Exit, all license rights granted to Tracon under the Collaborative Products License shall be terminated and 3DAlpha shall have the right to grant to a third party a License to Develop and Commercialize Collaborative Product under the Collaborative Product IP in the Field in the Collaborative Territory. 3DAlpha shall have the right to conduct, at 3DAlpha’s sole expense, clinical trials for a Collaborative Product at clinical sites in the Collaborative Territory in connection with a clinical trial primarily being conducted by 3DAlpha in the ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ for the purpose of seeking Regulatory Approval of a Collaborative Product in the 3DAlpha Territory or for a Collaborative Product outside the Field in the Collaborative Territory.

9.6Infringement by Third Parties. In the event either Party becomes aware of any Third Party infringement of the Collaborative Product IP in the Collaborative Territory (an “Infringement”), such Party shall promptly notify the other Party and the Parties shall confer in good faith regarding strategy for abating such infringement in view of its potential effect upon the Commercialization of Collaborative Products in the Collaborative Territory. [***], its Affiliates or their Licensees shall have the first right to bring an action for infringement of the Collaborative Product IP in the Collaborative Territory at its expense. Any recovery realized as a result of any such action or proceeding, whether by way of settlement or otherwise, shall first be used to reimburse the Parties for their costs in connection with such enforcement action and the balance shall be treated as Net Sales where [***] is the Leading Company. If [***] does not elect to bring an enforcement action against such Infringement, [***] shall have the right but not the responsibility to bring an enforcement action against such Infringement at its own expense and any recovery shall first be used to reimburse the Parties for their costs in connection with such enforcement action and the balance shall be treated as Net Sales where [***] is Leading Company.
