ARTICLE VI
TERM AND TERMINATION

6.1 Term. This Agreement shall be effective as of the Effective Date and, unless terminated earlier pursuant to its terms, shall continue in effect until expiry of the Royalty Term for all Products (“Term”).

6.2Termination Rights. If either Party materially breaches or materially defaults in the performance or observance of any of its respective obligations under this Agreement, and such breach or default is not cured within [***] days after the giving of written notice by the other Party specifying such

breach or default, then such other Party shall have the right to terminate this Agreement by providing the breaching Party written notice within [***] days following the expiration of such [***]-day period (such termination to be effective upon receipt of such termination notice).

6.3Effects of Termination. Upon the effective date of the termination of this Agreement for any reason, either Party may request in writing, and the other Party shall either, with respect to Confidential Information to which such other Party does not retain rights under the surviving provisions of this Agreement: (a) promptly destroy all copies of such Confidential Information in the possession of the other Party and confirm such destruction in writing to the requesting Party; or (b) promptly deliver to the requesting Party, at the other Party’s expense, all copies of such Confidential Information in the possession of the other Party; provided, however, the other Party shall be permitted to retain one copy of such Confidential Information for the sole purpose of performing any continuing obligations hereunder or for archival purposes.

ARTICLE VII
DISPUTE RESOLUTION

7.1Disputes. The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights or obligations hereunder. It is the objective of the Parties to establish under this ARTICLE VII procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. In the event that the Parties are unable to resolve such dispute within [***] days from the day that one Party had designated the issue as a dispute in written notice to the other Party, then either Party shall have the right to escalate such matter to senior management as set forth in Section 7.2.

7.2Escalation to Executive Officers. Either Party may, by written notice to the other Party, request that a dispute that remained unresolved by the Parties for a period of [***] days as set forth in Section 7.1 arising between the Parties in connection with this Agreement, or a dispute relating to material breach, be resolved by the Executive Officers for resolution, within [***] Business Days of their first consideration of such dispute.

7.3Arbitration. If the Executive Officers cannot resolve such dispute within [***] Business Days of their first consideration of such dispute, then upon the filing of a Request for Arbitration by either Party, such dispute shall be submitted to Arbitration in the State of Delaware and settled under the Commercial Arbitration Rules of the AAA. The place of arbitration shall be the State of Delaware. The language to be used in the arbitral proceedings shall be English. The dispute, controversy or claim referred to arbitration shall be decided in accordance with the laws of the State of Delaware. Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. Nothing

in this Section 7.3 will preclude either Party from seeking interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration, if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding.

ARTICLE VIII

8.2Assignment. This Agreement may be assigned, delegated or otherwise transferred by CASI, and any right or obligation under the Agreement can be assigned, delegated or transferred, by CASI without the prior written consent of Cleave. Cleave may, without the written consent of CASI, assign or otherwise transfer its financial rights to receive payments under this Agreement as a whole in connection with a change of control or corporate restructuring. If CASI assigns this Agreement to a Third Party, then CASI shall ensure that all financial obligations under ARTICLE III and the annual reporting under Section 2.7 shall also be assigned to, and be binding on, such Third Party acquirer. All of the terms and provisions of this Agreement shall be binding upon the Parties and their respective successors and assigns and inure to the benefit of the Parties and their respective successors and permitted assigns.

8.3Entire Agreement; Amendments. This Agreement contains the entire understanding of the Parties with respect to the subject matter hereof, and supersede all previous arrangements with respect to the subject matter hereof, whether written or oral, including the Existing License Agreement and all Confidential Information disclosed to a Party pursuant to the terms of the Existing License Agreement will be deemed to have been disclosed pursuant to this Agreement and will be deemed Confidential Information under this Agreement. This Agreement (including the Schedules hereto) may be amended, or any term hereof modified, only by a written instrument duly executed by authorized representatives of both Parties.

CASI Pharmaceuticals, Inc.

[***]

or to such other address as the Party to whom notice is to be given may have furnished to the other Party in writing in accordance herewith. Any such notice shall be deemed to have been given: (a) when delivered if

personally delivered on a Business Day (or if delivered or sent on a non-Business Day, then on the next Business Day), (b) on receipt if sent by overnight courier, or (c) on receipt if sent by mail.

8.5No Strict Construction. This Agreement has been prepared jointly and shall not be strictly construed against any Party.

8.6Headings. The captions or headings of the Sections or other subdivisions hereof are inserted only as a matter of convenience or for reference and shall have no effect on the meaning of the provisions hereof.

8.7No Implied Waivers; Rights Cumulative. No failure on the part of Cleave or CASI to exercise, and no delay in exercising, any right, power, remedy or privilege under this Agreement, or provided by statute or at law or in equity or otherwise, shall impair, prejudice or constitute a waiver of any such right, power, remedy or privilege or be construed as a waiver of any breach of this Agreement or as an acquiescence therein, nor shall any single or partial exercise of any such right, power, remedy or privilege preclude any other or further exercise thereof or the exercise of any other right, power, remedy or privilege.

8.8Severability. If any provision hereof should be held invalid, illegal or unenforceable in any respect in any jurisdiction, the Parties shall substitute, by mutual consent, valid provisions for such invalid, illegal or unenforceable provisions, which valid provisions best reflect the original intent of the Parties and in their economic effect are sufficiently similar to the invalid, illegal or unenforceable provisions that it can be reasonably assumed that the Parties would have entered into this Agreement with such valid provisions. In case such valid provisions cannot be agreed upon, the invalid, illegal or unenforceable of one or several provisions of this Agreement shall not affect the validity of this Agreement as a whole, unless the invalid, illegal or unenforceable provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid, illegal or unenforceable provisions.

8.9Interpretation. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise, (a) any definition of or reference to any agreement, instrument or other document herein shall be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein or therein), (b) any reference to any Laws herein shall be construed as referring to such Laws as they from time to time may be enacted, repealed or amended, (c) any reference herein to any Person shall be construed to include the Person's successors and assigns, (d) the words “herein”, “hereof” and “hereunder”, and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (e) any reference herein to the words “mutually agree” or “mutual written agreement” shall not impose any obligation on either Party to agree to any terms relating thereto or to engage in discussions relating to such terms except as such Party may determine in such Party's sole discretion, (f) all references herein to Articles, Sections or Exhibits shall be construed to refer to Articles, Sections or Exhibits of this Agreement, (g) the word “or” shall be construed to have the same meaning and effect as “and/or” unless the context dictates otherwise because the subjects of the conjunction are mutually exclusive, (h) a term not defined herein but reflecting a different part of speech than a term which is defined herein shall be interpreted in a correlative manner, (i) any reference in this Agreement to a “day” or a number of “days” (without explicit reference to “Business Days”) shall be interpreted as a reference to a calendar day or number of calendar days, and (j) if the last day for the exercise of any privilege or the discharge of any duty under this Agreement falls upon a day which is not a Business Day, then the Party

having such privilege or duty will have until the end of the next succeeding regular Business Day to exercise such privilege or to discharge such duty.

8.10Relationship of the Parties. It is expressly agreed that Cleave and CASI are independent contractors and that the relationship between the two Parties will not constitute a partnership, joint venture, or agency, including for Tax purposes. Neither Cleave nor CASI will have the authority to make any statements, representations, or commitments of any kind, or to take any action, which will be binding on the other Party, without the prior written consent of the other Party.

8.11Binding Effect; No Third Party Beneficiaries. As of the Effective Date, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. Except as expressly set forth in this Agreement, no Person other than the Parties and their respective Affiliates and permitted assigns shall be deemed an intended Third Party beneficiary hereunder or have any right to enforce any obligation of this Agreement.

Each Party agrees to duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such additional assignments, agreements, documents and instruments, as the other Party may at any time and from time to time reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes of, or to better assure of and confirm unto such other Party its rights and remedies under, this Agreement.

8.13Counterparts; Electronic Signatures. The Parties agree that each may execute this Agreement using electronic signatures. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
