In the event Viela agrees to transfer ownership of the Regulatory Approval to Hansoh, Hansoh will accept such transfer. Hansoh assumes full responsibility for the performance of the Licensed Affiliates pursuant to this Agreement and any breach by any Licensed Affiliates of this Agreement. Hansoh may request that additional Affiliates be added as Licensed Affiliates for purposes of enabling Hansoh to exercise the Licenses, subject to Viela’s consent, such consent not to be unreasonably withheld.

Section 10.2Indemnification by Viela. Viela shall indemnify, defend and hold Hansoh, its Affiliates, and their respective directors, agents and employees harmless (collectively, the “Hansoh Indemnitees”) from and against any and all Losses arising in connection with any and all Third Party Claims resulting or otherwise arising from (i) the Development, Manufacture or Commercialization of the Licensed Product outside the Territory, (ii) the breach of any obligations, warranties, representations or covenants hereunder by Viela or its Affiliates, or (iii) the intentional act or omission or the negligence of Viela or its Affiliates, except to the extent that such Losses arise from, are abased on, or result from any of activity or occurrence for which Hansoh is obligated to indemnify the Viela Indemnitees pursuant toSection 10.1.

Section 10.3Indemnification Procedures.

(a)Notice of Claim. All indemnification claims underSection 10.1 orSection 10.2, as applicable, will be made solely by any Hansoh Indemnitee or Viela Indemnitee (collectively, the “Indemnified Parties” and each an “Indemnified Party”). The Indemnified Party will give the indemnifying Party (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Losses and any legal proceeding initiated by a Third Party against the Indemnified Party as to which the Indemnified Party intends to make a request for indemnification underSection 10.1 orSection 10.2, as applicable, but in no event will the Indemnifying Party be liable for any Losses that result from any delay in providing such notice except to the extent that such delay actually prejudices the defense of such proceeding. Each Indemnification Claim Notice shall contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are known at such time). Together with the Indemnification Claim Notice, the Indemnified Party will furnish promptly to the Indemnifying Party copies of all notices and documents (including court papers) received by any Indemnified Party in connection with the Third Party Claim.

-28-

(b)Control of Defense. At its option, the Indemnifying Party may assume the defense of any Third Party Claim subject to indemnification as provided for inSection 10.1 orSection 10.2, as applicable, by giving written notice to the Indemnified Party within [***] ([***]) [***] after the Indemnifying Party’s receipt of an Indemnification Claim Notice. Upon assuming the defense of a Third Party Claim, the Indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel it selects, and such Indemnifying Party shall thereafter continue to defend such Third Party Claim in good faith. Should the Indemnifying Party assume the defense of a Third Party Claim (and continue to defend such Third Party Claim in good faith), the Indemnifying Party will not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim, unless the Indemnifying Party has failed to assume the defense and employ counsel in accordance with thisSection 10.3.

(c)Right to Participate in Defense.Without limiting the foregoing, any Indemnified Party will be entitled to participate in the defense of a Third Party Claim for which it has sought indemnification hereunder and to employ counsel of its choice for such purpose;provided,however, that such employment will be at the Indemnified Party’s own expense unless (i) the employment thereof has been specifically authorized by the Indemnifying Party in writing, or (ii) the Indemnifying Party has failed to assume the defense (or continue to defend such Third Party Claim in good faith) and employ counsel in accordance with thisSection 10.3, in which case the Indemnified Party will be allowed to control the defense at the Indemnifying Party’s expense.

(d)Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnified Party (i) becoming subject to injunctive or other relief or (ii) admitting any breach or violation of contract or law, the Indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its reasonable discretion, will deem appropriate (provided,however, that such terms shall include a complete and unconditional release of the Indemnified Party from all liability with respect thereto). With respect to all other Losses in connection with Third Party Claims, where the Indemnifying Party has assumed the defense of the Third Party Claim in accordance withSection 10.3(b), the Indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss;provided, it obtains the prior written consent of the Indemnified Party (which consent will be not be unreasonably withheld, conditioned or delayed). The Indemnifying Party that has assumed the defense of (and continues to defend) the Third Party Claim in accordance withSection 10.3(b) will not be liable for any settlement or other disposition of a Loss by an Indemnified Party that is reached without the written consent of such Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to, or settle, compromise or discharge, any Third Party Claim without first offering to the Indemnifying Party the opportunity to assume the defense of the Third Party Claim in accordance withSection 10.3(b).

(e)Cooperation. If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection with such Third Party Claim. Such cooperation will include access during normal business hours afforded to the Indemnifying Party

-29-

to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party will reimburse the Indemnified Party for all its reasonableout-of-pocket expenses incurred in connection with such cooperation.

(f)Expenses of the Indemnified Party. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Third Party Claim will be reimbursed on a calendar quarter basis by the Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

Section 10.4LIMITATION OF LIABILITY. EXCEPT TO THE EXTENT INCLUDED IN LOSSES RESULTING FROM A THIRD PARTY CLAIM FOR WHICH ONE PARTY IS OBLIGATED TO INDEMNIFY THE OTHER PARTY (OR AN INDEMNITEE OF SUCH OTHER PARTY) PURSUANT TO THISARTICLE 10 ORARTICLE 13 IN NO EVENT WILL EITHER PARTY SHALL BE LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL (INCLUDING WITHOUT LIMITATION LOST PROFITS OR REVENUES), INDIRECT, PUNITIVE, SPECIAL, OR LIQUIDATED DAMAGES OF ANY KIND UNDER OR IN CONNECTION WITH THIS AGREEMENT, OTHER THAN IN THE EVENT OF INTENTIONAL MISREPRESENTATION, FRAUD OR WILLFUL MISCONDUCT.

Hansoh shall have the exclusive right to enforce Hansoh Patents in the Territory, and Viela shall have the right to enforce Hansoh Patents outside the Territory. Viela shall also have the right, but not the obligation, to sue such alleged infringers in the Territory in connection with the Licensed IP or Joint Patents. Viela shall consult with Hansoh prior to initiating any such infringement suit in the Territory to ensure that the intended course of action is not likely to adversely affect Hansoh’s Development and Commercialization of the Licensed Product within the Territory. In the event that Viela elects not to initiate a lawsuit or take other reasonable action with respect to an infringement described in thisSection 12.4 of any Licensed Patents owned by Viela or Joint Patents in the Territory, or any Hansoh Patent or Joint Patent outside the Territory, Hansoh shall have the right, but not the obligation, to initiate such suit or take such other action, after providing [***] ([***]) [***] (or [***] ([***]) [***] in the event there is a time limit) notice to Viela and giving good faith consideration to Viela’s reason(s) for not initiating a suit or taking other action.

(b) If one Party elects to bring suit or take action under thisSection 12.4 against an infringement, then the other Party shall have the right, prior to commencement of the suit or action, to join any such suit or action. Each Party shall provide to the Party enforcing any such rights under thisSection 12.4 reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by Applicable Law to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts, shall reasonably consider the other Party’s comments on any such efforts, and shall consult the other Party in any important aspects of such enforcement, including determination of material litigation strategy and filing of important papers to the competent court. Neither Party shall settle any claim, suit or action that it brought under thisSection 12.4 involving Licensed IP or Joint Patents without the prior written consent of the other Party, such consent not to be unreasonably withheld, delayed or conditioned.

(c) If either Party recovers monetary damages from any Third Party in a suit or action brought underSection 12.4 or any royalties, milestones or other payments from a license agreement with a Third Party resulting from any alleged infringement of Licensed IP or Joint Patents, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation, action or license negotiations, and any remaining amounts shall be retained by the Party bringing the suit or action; provided if such Party is Hansoh, such remaining amounts shall be included in the Net Sales in the applicable calendar year.

Section 12.5Infringement of Third Party Intellectual Property. If, during the Term, either Party receives any notice, claim or proceedings from any Third Party alleging infringement of that Third Party’s Intellectual Property in the Territory by reason of either Party’s activities in relation to the Agreement, either Party receiving such notice shall promptly notify the other Party of such notice, claim or proceeding and Hansoh shall have the first right, but not the obligation, to resolve such infringement or such possibility, including entering into a Third Party license with

-36-

such Third Party with Viela’s prior written consent; provided that Hansoh shall not, without Viela’s prior written consent, enter into any compromise or settlement that (i) admits the invalidity of any Licensed Patent or Joint Patent in the Territory or elsewhere in the world, or (ii) requires Viela to relinquish any Licensed Patent or Joint Patent in the Territory or elsewhere in the world. Viela shall have the right to consult with Hansoh about any such litigation and to participate in and be represented by independent counsel in such litigation at Viela’s own expense. In the event that Hansoh elects not to resolve such infringement or such possibility of infringement, then (a) Viela shall, at Hansoh’s cost and expense, resolve such infringement or such possibility, and (b) Viela shall consider in good faith Hansoh’s comments with respect to strategy and negotiation of any action or proceeding. Hansoh shall, at the request of Viela, agree to timely commence or join in any necessary litigation, and in any event to cooperate with Viela in such litigation. Hansoh shall have the right to consult with Viela about any such litigation and to participate in and be represented by independent counsel in such litigation at Hansoh’s own expense.

Section 12.6Publications. Viela shall have the right to publish, present, or announce, either orally or in writing, any results or data relating the Licensed Compound or Licensed Product, without the need to seek consent from Hansoh, subject toArticle 13. Except as required by Applicable Law Hansoh shall not publish results or data without prior written consent from Viela, such consent not to be unreasonably withheld. If Hansoh desires to publish, present, or announce, either orally or in writing, any results or data relating the Licensed Compound or Licensed Product, Hansoh will submit to Viela such proposed publication, presentation or announcements for approval by Viela at least [***] ([***]) [***] prior to the proposed date of publication or disclosure, whichever is earlier. Notwithstanding any approval by Viela, (a) at Viela’s request, Hansoh will delay publication or disclosure for such reasonable period, not to exceed an additional [***] ([***]) [***], to permit the filing of patent applications; and (b) in no event will Hansoh publish Viela’s Confidential Information without Viela’s prior express written consent.

ARTICLE 13

Section 13.1Confidential Information. As used in this Agreement, the term “Confidential Information” means all information, whether it be written or oral, including all production schedules, lines of products, volumes of business, processes, new product developments, product designs, formulae, technical information, laboratory data, clinical data, patent information,know-how, trade secrets, financial and strategic information, marketing and promotional information and data, and other material relating to any products, projects or processes of one Party (the “Disclosing Party”) that is provided to, or otherwise obtained by, the other Party (the “Receiving Party”) in connection with this Agreement (including information exchanged prior to the date hereof in connection with the transactions set forth in this Agreement). Notwithstanding the foregoing sentence, Confidential Information shall not include any information or materials that:

(i) were already known to the Receiving Party (other than under an obligation of confidentiality), at the time of disclosure by the Disclosing Party, to the extent such Receiving Party has documentary evidence to that effect;

-37-

(ii) were generally available to the public or otherwise part of the public domain at the time of disclosure thereof to the Receiving Party;

(iii) became generally available to the public or otherwise part of the public domain after disclosure or development thereof, as the case may be, and other than through any act or omission of a Party in breach of such Party’s confidentiality obligations under this Agreement;

(iv) were disclosed to a Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the Disclosing Party not to disclose such information to others; or

(v) were independently discovered or developed by or on behalf of the Receiving Party without the use of the Confidential Information belonging to the other Party, to the extent such Receiving Party has documentary evidence to that effect.

Section 13.2Confidentiality Obligations. During the Term and for [***] ([***]) [***] thereafter, either Party shall keep all Confidential Information received from or on behalf of the other Party with the same degree of care with which it maintains the confidentiality of its own Confidential Information, but in all cases no less than a reasonable degree of care. Neither Party shall use such Confidential Information for any purpose other than in performance of this Agreement or disclose the same to any other person other than to such of its and its Affiliates’ directors, officers, managers, employees, independent contractors (e.g., CRO, SMO, and investigational sites), agents, consultants or, solely with respect to Hansoh, its sublicensees who have a need to know such Confidential Information to implement the terms of this Agreement or enforce its rights under this Agreement;provided,however, that a Receiving Party shall advise any of its and its Affiliates’ directors, officers, managers, employees, independent contractors (e.g., CRO, SMO, and investigational sites), agents, consultants or, solely with respect to Hansoh, its sublicensees, who receives such Confidential Information of the confidential nature thereof and of the obligations contained in this Agreement relating thereto, and the Receiving Party shall ensure (including, in the case of a Third Party, by means of a written agreement with such Third Party having terms at least as protective as those contained in thisARTICLE 13) that all such directors, officers, managers, employees, independent contractors (e.g., CRO, SMO, and investigational sites), agents, consultants or, solely with respect to Hansoh, its sublicensees comply with such obligations. Upon termination of this Agreement, the Receiving Party shall return or destroy all documents, tapes or other media containing Confidential Information of the Disclosing Party that remain in the possession of the Receiving Party or its directors, officers, managers, employees, independent contractors (e.g., CRO, SMO, and investigational sites), agents, consultants or, solely with respect to Hansoh, its sublicensees, except that the Receiving Party may keep one copy of the Confidential Information in the legal department files of the Receiving Party, solely for archival purposes. Such archival copy shall be deemed to be the property of the Disclosing Party, and shall continue to be subject to the provisions of thisARTICLE 13. It is understood that receipt of Confidential Information under this Agreement will not limit the Receiving Party from assigning its employees to any particular job or task in any way it may choose, so long as such recipient shall have agreed in writing to maintain the confidentiality of Confidential Information in accordance with the terms of this Agreement. The Receiving Party shall remain responsible for any failure by any such Person to treat such Confidential Information as required by this Agreement. If the

-38-

Receiving Party is required to disclose Confidential Information in response to a court order or subpoena or to comply with the rules or regulations of regulatory agency or governmental agency in any country, the Receiving Party shall provide prior notice of such intended disclosure to the Disclosing Party in sufficient time to enable the Disclosing Party to object or seek a limitation as to the scope of the disclosure.

Section 13.3Permitted Disclosure and Use. NotwithstandingSection 13.2, (i) either Party may disclose Confidential Information belonging to the other Party only to the extent such disclosure is reasonably necessary to: (a) comply with or enforce any of the provisions of this Agreement; (b) comply with Applicable Laws; (c) respond to subpoena or other compulsory legal process; or (d) disclose Confidential Information related to the Licensed Product only to the extent such disclosure is made to a governmental authority, including Regulatory Authority, and is reasonably necessary to obtain or maintain Regulatory Approval of a Licensed Product, as applicable. If a Party deems it necessary to disclose Confidential Information of the other Party pursuant to thisSection 13.3, such Party shall give advance written notice of such disclosure to the other Party sufficient to permit such other Party reasonable opportunity to object to such disclosure or to take measures to ensure confidential treatment of such information, including seeking a protective order or other appropriate remedy.

Section 13.4Confidentiality of Agreement Terms. The Parties acknowledge that the terms of this Agreement shall be treated confidentially as Confidential Information of both Parties. Notwithstanding the foregoing, such terms may be disclosed by a Party to investment bankers, actual or potential investors or acquirers, and their respective advisors, in the context of a potential transaction, each of whom prior to disclosure must be bound by similar obligations of confidentiality andnon-use at least equivalent in scope to those set forth in thisARTICLE 13. In addition, a copy of this Agreement may be filed by a Party with the U.S. Securities and Exchange Commission, or similar regulatory agency in a country other than the United States or of any stock exchange or other securities trading institution, as required by Applicable Law. In connection with any such filing, such Party shall endeavor to obtain confidential treatment of economic and trade secret information. In any event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information except as permitted hereunder. The Party subject to such disclosure requirement shall, if reasonably practicable under the circumstances, provide the other Party with a reasonable opportunity to review and comment in advance on the disclosing Party’s proposed disclosure and such disclosing Party shall consider in good faith any comments thereon provided by the other Party.

Section 13.5Notification. The Receiving Party shall notify the Disclosing Party promptly upon discovery of any unauthorized use or disclosure of the Disclosing Party’s Confidential Information, and will cooperate with the Disclosing Party in any reasonably requested fashion to assist the Disclosing Party to regain possession of such Confidential Information and to prevent its further unauthorized use or disclosure.
