Subject to Section 7.2, Dong-A, its Affiliates, and each of their respective directors, officers, trustees, shareholders, employees, and agents (collectively, “Dong-A Indemnitees”) will be indemnified, defended by counsel reasonably acceptable to Dong-A, and held harmless by NeuroBo from and against any Loss of any kind or nature which are incurred by virtue of or result from,

(b) any breach of the covenants or other obligations of NeuroBo under this Agreement,

except to the extent that any claims have arisen from the gross negligence or willful misconduct of any Dong-A Indemnitee or the breach of an obligation under this Agreement by any Dong-A Indemnitee.

8.3 Defense of Claims

(a) In the case of any claim for indemnification under Section 8.1 (if NeuroBo) or Section 8.2 (if Dong-A) arising from a claim of a Third Party, an indemnified party must give prompt notice and, subject to the following sentence, in no case later than [***] days after the indemnified party’s receipt of notice of such claim, to the indemnifying party of any claim of which such indemnified party has knowledge and as to which it may request indemnification hereunder. The failure to give such notice will not, however, relieve the indemnifying party of its indemnification obligations except to the extent that the indemnifying party is actually harmed thereby.

(b) The indemnifying party will have the right to defend and to direct the defense against any such claim in its name and at its expense, and with counsel selected by the indemnifying party unless (i) the indemnifying party acknowledges fully its obligations to the indemnified party(ies) under this Agreement within [***] days after receiving notice of such Third Party claim; (ii) the applicable Third Party claim alleges fraud; (iii) there is a conflict of interest between the indemnified party and the indemnifying party in the conduct of such defense; (iv) the Third Party claim is criminal in nature, could reasonably be expected to lead to criminal proceedings, or seeks an injunction or other equitable relief against the indemnified party; (v) the Third Party claim seeks injunctive relief or other equitable remedies against the indemnified party(ies); and/or (vi) the indemnified party is NeuroBo and the Third Party is a customer of NeuroBo.

(c) If the indemnifying party elects, and is entitled, to compromise or defend such claim, it will within [***] days of receipt of notice (or sooner, if the nature of the claim so requires) notify the indemnified party of its intent to do so, and the indemnified party must, at the request and expense of the indemnifying party, cooperate in the defense of such claim.

(d) If the indemnifying party elects not to compromise or defend such claim, fails to notify the indemnified party of its election as herein provided or refuses to acknowledge or contests its obligation to indemnify under this Agreement, the indemnified party may pay, compromise or defend such claim.

(e) Except as set forth in the immediately preceding subsection, the indemnifying party will have no indemnification obligations with respect to any such claim which will be settled by the indemnified party without the prior written consent of the indemnifying party (which consent may not be unreasonably withheld or delayed); provided, however, that notwithstanding the foregoing, the indemnified party will not be required to refrain from paying any claim that has matured by an order, unless an appeal is duly taken therefrom and exercise thereof has been stayed, nor will it be required to refrain from paying any claim where the delay in paying such claim would result in the foreclosure of a lien upon any of the property or assets then held by the indemnified party or where any delay in payment would cause the indemnified party material economic loss.

(f) The indemnifying party’s right to direct the defense will include the right to compromise or enter into an agreement settling any claim by a Third Party; provided that no such compromise or settlement will obligate the indemnified party to agree to any settlement that requires the taking or restriction of any action (including the payment of money and competition restrictions) by the indemnified party other than the delivery of a release, except with the prior written consent of the indemnified party (such consent to be withheld or delayed only for a good faith reason).

(g) Notwithstanding the indemnifying party’s right to compromise or settle in accordance with the immediately preceding sentence, the indemnifying party may not settle or compromise any claim over the objection of the indemnified party; provided, however, that consent by the indemnified party to settlement or compromise will not be unreasonably withheld or delayed.

(h) The indemnified party will have the right to participate in the defense of any claim with counsel selected by it subject to the indemnifying party’s right to direct the defense. The fees and disbursements of such counsel will be at the expense of the indemnified party; provided, however, that, in the case of any claim which seeks injunctive or other equitable relief against the indemnified party, the fees and disbursements of such counsel will be at the expense of the indemnifying party.

8.4 Non-Third Party Claims. Any claim which does not result from a Third Party claim will be asserted by a notice to the other Party and will be identified as a “DIRECT INDEMNITY CLAIM NOTICE.” The recipient of such notice will have a period of [***] days after receipt of such notice within which to respond thereto. During such [***]-day period, the recipient will have the right to cure any applicable breach of this Agreement. If the recipient does not respond within such [***] days and does not cure the applicable breach, the recipient will be deemed to have accepted responsibility for the Losses set forth in such notice and will have no further right to contest the validity of such notice. If the recipient responds within such [***] days after the receipt of the notice and rejects such claim in whole or in part, the Party delivering will be free to pursue such remedies as may be available to it under contract or applicable law.

Except as permitted in the exercise of the licenses and rights granted under this Agreement, Receiving Party shall not disclose or transfer any Confidential Information to any Third Party, without the specific prior written approval of the Disclosing Party, except to the extent required by law or governmental or court order to be disclosed by Receiving Party, provided that Receiving Party gives the Disclosing Party prompt notice of such requirement (if permitted by law) prior to such disclosure and cooperates with the Disclosing Party in the latter’s attempt, if any, to prevent such disclosure or in obtaining a protective or similar order with respect to the Confidential Information to be disclosed.

9.4 Return of Information. The Disclosing Party retains ownership of all Confidential Information disclosed or made available to Receiving Party. Upon any termination, cancellation, or expiration of this Agreement, or upon the Disclosing Party’s request for any reason (other than in breach of this Agreement), Receiving Party shall return promptly to the

Disclosing Party (or destroy at the Disclosing Party’s request with a signed certification thereof) the originals and all copies (without retention of any copy) of any written documents, tools, materials, or other tangible items containing or embodying Confidential Information; provided, however, that Receiving Party shall be entitled to retain such originals and copies of Confidential Information of the Disclosing Party (which may be in electronic form) solely for archival purposes, defense of claims, and as are necessary to Receiving Party’s use and exploitation, as permitted by this Agreement, of any rights retained by Receiving Party following such termination, cancellation, expiration or request.

9.5 Remedies. Receiving Party agrees that its obligations provided in this Section 9 are necessary and reasonable in order to protect the Disclosing Party and its business, and expressly agrees that monetary damages would be inadequate to compensate the Disclosing Party for any breach by the Receiving Party of its covenants and agreements set forth in this Agreement. Accordingly, each Party agrees and acknowledges that any such breach or threatened breach may allow the Receiving Party or Third Parties to unfairly compete with the Disclosing Party resulting in irreparable injury to the Disclosing Party and that, in addition to any other remedy that may be available, in law, in equity or otherwise, the Disclosing Party shall be entitled to seek and obtain (without being required to post a bond or other security) injunctive relief against the threatened breach of this Agreement or the continuation of any such breach by the Receiving Party, without the necessity of proving actual damages.

9.6 Publicity. Except as necessary to comply with any applicable laws or regulations, each Party agrees not to issue any press release or public statement disclosing the terms of this Agreement without the prior written consent of the other Party, not to be unreasonably withheld, conditioned or delayed. Prior to being released or made, a copy of all press releases and public statements which a Party intends to issue or make regarding the terms of this Agreement, shall be provided to the other Party for approval.

10. GENERAL PROVISIONS

10.1 Notices. All notices, consents, and approvals under this Agreement must be delivered in writing by courier, electronic facsimile (fax), or certified or registered mail, (postage prepaid and return receipt requested) to the other Party; and shall be effective upon receipt or three (3) business days after being deposited in the mail, whichever occurs sooner. Notices to Parties shall be sent to the addresses set forth at the beginning of this Agreement. Notice of change of address shall be given in the same manner as other communications.

10.2 Force Majeure. No Party shall be liable for any failure to perform its obligations under this Agreement if prevented from doing so by a cause or causes beyond its reasonable control and not the fault of the nonperforming Party, and the nonperforming Party has been unable to avoid or overcome the act or event by the exercise of due diligence, including, by way of example and without limitation, war, flood, fire, earthquake, riots, strikes, acts of God or public enemy, restraints of government, terrorist acts, and military action.

10.3 Assignment. Neither Party may assign or transfer any of its rights under this Agreement, voluntarily, involuntarily, or by operation of law, or in any other manner, without the prior written consent of the other Party; provided, however, that either Party may assign its

rights under this Agreement in connection with a merger, consolidation, or sale of substantially all of its assets with prior written notice to the other Party and if the successor entity agrees in writing to be bound by all of the terms and conditions of this Agreement. Any purported assignment or transfer of rights in violation of this section is null and void. Subject to the foregoing, this Agreement shall bind and inure to the benefit of the Parties and their respective successors and permitted assigns.

10.4 Waivers. Any waiver or failure to enforce any provision of this Agreement on one occasion shall not be deemed a waiver of any other provision or of such provision on any other occasion.

10.6 Remedies. The Parties’ rights and remedies under this Agreement are cumulative. It is understood and agreed that notwithstanding any other provisions of this Agreement, a breach by a Party under this Agreement shall cause the other Parties irreparable damage for which recovery of money damages would be inadequate, and that, in addition to any and all remedies available at law, the other Parties shall be entitled to seek timely injunctive relief to protect their rights under this Agreement. If any legal action is brought to enforce this Agreement, the prevailing Party shall be entitled to receive its reasonable attorneys’ fees, court costs, and other collection expenses, in addition to any other relief it may receive.

10.7 Governing Law. The laws of the State of New York (without giving effect to its conflicts of law principles) govern all matters arising out of or relating to this Agreement and all of the transactions it contemplates, including without limitation, its validity, interpretation, construction, performance, and enforcement.

10.8 Submission to Jurisdiction/Waiver of Jury Trial. EACH OF THE PARTIES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, AND EMPLOYEES HEREBY IRREVOCABLY AND UNCONDITIONALLY: (I) SUBMITS FOR ITSELF AND ITS PROPERTY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR FOR RECOGNITION AND ENFORCEMENT OF ANY JUDGMENT IN RESPECT THEREOF, TO THE NON-EXCLUSIVE GENERAL JURISDICTION OF THE COURTS OF NEW YORK, THE COURTS OF THE UNITED STATES OF AMERICA FOR NEW YORK, AND APPELLATE COURTS FROM ANY THEREOF; (II) CONSENTS TO THE FULLEST EXTENT PERMITTED BY LAW THAT ANY SUCH ACTION OR PROCEEDING MAY BE BROUGHT IN SUCH COURTS AND HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY AND IN ANY ACTION OR OTHER PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT AND AGREES NOT TO PLEAD OR CLAIM THE SAME, AND (III) AGREES TO THE FULLEST EXTENT BY LAW THAT SERVICE OF PROCESS IN ANY SUCH ACTION OR PROCEEDING MAY BE

Nothing contained herein shall be construed as creating any agency, partnership, or other form of joint enterprise between the Parties.
