Execution Version

except to the extent that such Losses arise from (i) a breach by TIANSHI of any terms of this Agreement (including its obligations to comply with the terms of the Third Party Agreements), or (ii) the gross negligence or willful misconduct of TIANSHI or its Affiliates or (iii) claims for which TIANSHI is required to indemnify CASI pursuant to Section 9.1 (Indemnification by TIANSHI).

9.2 Indemnification by TIANSHI.  TIANSHI hereby agrees to indemnify, defend, and hold CASI, its Affiliates, and their respective directors, agents, and employees harmless from and against any and all Losses arising in connection with any and all Third Party Claims arising from or relating to (a) any breach by TIANSHI or its Affiliates or Sublicensees of any of its representations, warranties, covenants, or obligations under to this Agreement including any failure to comply with any obligations under or terms of the Adimab Agreement, Cellca Agreement or the AGC Agreement, (b) any violation of Law, gross negligence, or willful misconduct by TIANSHI or its Affiliates or Sublicensees or their respective officers, directors, employees, agents, or consultants in performing any obligations or exercising any rights under this Agreement, and (c) the Exploitation of the Licensed Compounds or Licensed Products by TIANSHI or its Affiliates or Sublicensees (including any product liability Losses resulting therefrom), in each case ((a)-(c)), except to the extent that such Losses arise from (i) a breach by CASI of any terms of this Agreement, or (ii) the gross negligence or willful misconduct of CASI or its Affiliate or (iii) claims for which CASI is required to indemnify TIANSHI pursuant to Section 9.1 (Indemnification by CASI).

9.3 Indemnification Procedures.

9.3.1 Notice of Claim.  All indemnification claims in respect of any indemnitee seeking indemnity under Section 9.1 (Indemnification by CASI) or Section 9.2 (Indemnification by TIANSHI), as applicable (collectively, the “Indemnitees” and each, an “Indemnitee”) will be made solely by the corresponding Party (the “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 under Section 9.1 (Indemnification by CASI) or Section 9.2 (Indemnification by TIANSHI), as applicable, but in no event will the Indemnifying Party be liable for any Losses that result from any delay in providing such notice that materially prejudices the defense of such proceeding.  Each Indemnification Claim Notice will 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 Indemnitee in connection with the Third Party Claim.

9.3.2 Control of Defense.  At its option, the Indemnifying Party may assume the defense of any Third Party Claim subject to indemnification as provided for in Section 9.1 (Indemnification by CASI) or Section 9.2 (Indemnification by TIANSHI), as applicable, by giving written notice to the Indemnified Party within 30 days 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 will 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 or any other Indemnitee for any legal expenses subsequently incurred by such Indemnified Party or other Indemnitee in connection with the analysis, defense, or settlement of the Third

- 44 -

Execution Version

Party Claim, unless the Indemnifying Party has failed to assume the defense and employ counsel in accordance with this Section 9.3 (Indemnification Procedures).

9.3.3 Right to Participate in Defense.  Without limiting Section 9.3.2 (Control of Defense), any Indemnitee 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 Indemnitee’s own expense unless (a) the employment thereof has been specifically authorized by the Indemnifying Party in writing, or (b) 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 this Section 9.3 (Indemnification Procedures), in which case, the Indemnified Party will be allowed to control the defense.

9.3.4 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 Indemnitee becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnitee in any manner, 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 will include a complete and unconditional release of the Indemnified Party from all liability with respect thereto), and will transfer to the Indemnified Party all amounts that said Indemnified Party will be liable to pay prior to the time of the entry of judgment.  With respect to all other Losses in connection with Third Party Claims, if the Indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 9.3.2 (Control of Defense), then 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 that it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld).  The Indemnifying Party that has assumed the defense of (and continues to defend) the Third Party Claim in accordance with Section 9.3.2 (Control of Defense) will not be liable for any settlement or other disposition of a Loss by an Indemnitee 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 Indemnitee 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 with Section 9.3.2 (Control of Defense).

9.3.5 Cooperation.  If the Indemnifying Party chooses to defend or prosecute any Third Party Claim, then the Indemnified Party will, and will cause each other Indemnitee 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 to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnitees 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 documented, reasonable external expenses incurred in connection with such cooperation.

- 45 -

Execution Version

9.3.6 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.

9.4 LIMITATION OF LIABILITY.  NEITHER PARTY WILL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES, OR INDIRECT LOST PROFITS OR INDIRECT LOST REVENUES, ARISING FROM OR RELATING TO THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.  NOTWITHSTANDING ANY PROVISION IN THIS AGREEMENT TO THE CONTRARY, NOTHING IN THIS SECTION 9.4 (LIMITATION OF LIABILITY) IS INTENDED TO OR WILL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 9.1 (INDEMNIFICATION BY CASI) OR SECTION 9.2 (INDEMNIFICATION BY TIANSHI), OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS UNDER Article 10 (CONFIDENTIALITY) OR FOR CASI’S BREACH OF SECTION 2.3 (NON-COMPETE); PROVIDED THAT NOTHING IN THIS AGREEMENT SHALL LIMIT TIANSHI’s LIABILITY TO CASI TO THE EXTENT THAT CASI INCURS LIABILTY UNDER EITHER OF THE THIRD PARTY AGREEMENTS OR THE AGC AGREEMENT AS A RESULT OF ANY ACT OR OMISSION OF TIANSHI, ITS AFFILIATES OR SUBLICENSEES AND CASI CANNOT LIMIT ITS LIABILITY UNDER SUCH THIRD PARTY AGREEMENT OR AGC AGREEMENT.

Number and Selection of Arbitrators.  The number of arbitrators will be three, who will be selected as follows: each of TIANSHI and CASI will nominate one arbitrator, in the case of the claimant at the same time as serving the Notice of Arbitration and, in the case of the respondent, at the same time as serving the Answer, and those Party-nominated arbitrators will unanimously nominate the third arbitrator (who will act as president of the Arbitral Tribunal, referred to in this clause 1 as the “President Arbitrator”), within 10 Business Days after the appointment of the last Party-nominated arbitrator. Each of the three arbitrators will have the following qualifications (as applicable, the “Qualifications”): for any other dispute, the Qualifications must be an attorney who has been admitted to practice law for at least 10 years and who has significant experience in the pharmaceutical or biologics industry; provided that if a Party is unable to find an arbitrator with the applicable Qualifications to nominate with respect to a particular Dispute, then it may request the Administrator of the ICDR to find and appoint such an arbitrator on its behalf.  If the Party-nominated arbitrators are unable to agree upon the nomination of the President Arbitrator within 10 Business Days after the nomination of the last Party-nominated arbitrator, then the Administrator of the ICDR will appoint such President Arbitrator (with the applicable Qualifications) within 10 Business Days thereafter.

2. Limitation of Damages.  The Arbitral Tribunal will be empowered to award damages only to the extent of actual damages suffered, and only to the extent consistent with Section 9.4 (Limitation of Liability) of this Agreement, in each case, regardless of whether any such damages are contained in a proposal submitted by a Party. The Arbitral Tribunal will not be authorized to reform, modify, or materially change this Agreement. Each Party will bear an equal share of the arbitrators’ fees and any administrative fees of arbitration.

3. Evidence.  Notwithstanding any provision of the Arbitration Rules each Party will be permitted to obtain production of documents pursuant to ARTICLE 3 of the International Bar Association Rules on the Taking of Evidence in International Arbitration as current on the date of this Agreement (the “IBA Rules”).
