 D. Termination by Company for “Cause.” The Company may

Turpitude. Upon the Company believing that it has just cause to terminate Executive, Company shall provide written notice to Executive of its belief and the reason(s). Thereafter, Executive shall have twenty (20) business days to address the
Company’s stated reason(s) and to cure the reason(s) cited by the Company. If the Executive fails to cure the stated reason(s) cited by the Company, the Company shall then provide the Executive with written notice of its decision at least
15 days in advance of the desired termination date, together with written documentation of the Cause that is the basis for the Company to seek such early termination. The Executive will continue to provide services to the Company from the date
he receives the notice and documentation until the desired termination date, if requested to do so by the Company. The Executive will also be entitled to the Severance Benefits described in this Section 4G (“Severance Benefits”). 

E. Termination by Company Without Cause. The Company may obtain an early discontinuance of the services of the Executive during the
term of this Agreement for any reason other than for Cause, the death of the Executive, or the illness or incapacity of the Executive, by providing the Executive with at least 90 days’ notice of its decision, in writing, in advance of the
desired discontinuance of services date. The Executive will be obligated to continue to perform his services for the Company only through the date of the desired discontinuance of services date, and the Executive will be compensated in the ordinary
course, and will receive all of his other employment benefits, including all PTO accruals, until such termination date. The Executive will also be paid his Base Salary until the date of the expiration of the Term of this Agreement. In the event that
the expiration date of the Term is more than 12 months from the date of termination of the Executive’s employment, or in the event the Executive is otherwise paid his Base Salary for longer than 12 months after the date of
termination, the Executive’s non-solicitation and non-competition obligations set forth in Section 5 of this Agreement shall continue until while the Executive
is being paid his Base Salary; i.e., the Executive’s obligations under Section 5 shall continue during the period the Executive is being paid his Base Salary. 

F. Termination by Executive for Good Reason. The Executive may obtain an early discontinuance of his services during the term of this
Agreement for Good Reason as set forth in Section 12 of this Agreement. The Executive will be obligated to continue to perform his services for the Company only through the date of the discontinuance of services date, and the Executive will be
compensated in the ordinary course, and will receive all of his other employment benefits, including all PTO accruals, until such termination date. The Executive will also be paid his Base Salary until the date of the expiration of the Term of this
Agreement. In the event that the expiration date of the Term is more than 12 months from the date of termination of the Executive’s employment, the Executive’s non-solicitation and non-competition obligations set forth in Section 5 of this Agreement shall continue until the expiration of the Term; i.e., the Executive’s obligations under Section 5 shall continue during the

 G. Salary Continuation. Upon voluntary termination or termination for Cause, the
Executive will be entitled to salary continuation for the lesser of either a period of twelve (12) months following termination of his employment, or a period equal to the remainder of the Term, in accordance with subsections A and D,
respectively. Upon termination without Cause, or for Good Reason, the Executive will be entitled to salary continuation for the remainder of the Term in accordance with subsection E and F, respectively, of this Section 4. Upon termination
without Cause prior to the end of the Performance Period, as defined in the Earn-Out Agreement between the Parties of even date, Executive will be entitled to his Base Salary for three (3) years from the

 5. Non-Solicitation; Non-Competition. 
 Executive acknowledges
and agrees that his expertise and experience in the business of the Company is essential for the growth, success and stability of the Company. Executive further agrees that Company has global presence, and that any geographic limitation on the
restrictions contained in this paragraph would be of no impact because of the Company’s global presence and Executive’s duties and knowledge. Executive further acknowledges and understands that the covenants set forth in this
Section 5 are reasonable and necessary and part of the consideration provided to Executive by Company. Therefore, in consideration of the various covenants and obligations of the Company pursuant to this Agreement and the other agreements
described herein, as long as Executive receives the Base Salary, or if applicable, amounts paid during the Non-Compete Period, Executive shall not, directly or indirectly:

other solicitation not addressed specifically to such Person) to: (i) terminate such employment, and/or (ii) accept employment or enter into any consulting arrangements with any Person other than the Company; provided, however, this
provision is not intended to and does not preclude Executive, on behalf of himself or another, from offering employment to or hiring any Person in the employment of the Company who initiates contact with Executive, inquires about employment or
consulting opportunities, and/or otherwise responds to a general employment or similar notice issued on behalf of the Executive or another Person, in each case, without any inducement from or on behalf of the Executive. The prohibitions in this
Section 5.a. include, but are not limited to using social media, such as LinkedIn, Facebook, and/or Twitter, to directly communicate with any employee, customer, supplier, licensee, licensor, Prospective Customer or other business relation of
the Company or any of its Affiliates, it being understood that any general update to Executive’s title or employer on Executive’s profile on such social media shall not be considered such direct communication;

licensor, customer, Prospective Customer, or other business relation of the Company, or induce, encourage or cause any such supplier, licensee, licensor, customer, Prospective Customer, or other business relation to reduce or terminate its business
relationship with the Company; 

  

	 	c.	During the employment relationship and one (1) year following the termination of the employment relationship (the “Non-Compete Period”), either for himself or for
any other Person, own, manage, control, participate in, consult with, render services for, permit his name to be used or in any other manner or capacity engage in any business or enterprise which constitutes a Competitive Business. For purposes of
this Agreement, the term “participate” includes any direct or indirect interest in any enterprise, whether as an officer, director, employee, partner, sole proprietor, agent, representative, independent contractor, consultant, executive,
franchisor, franchisee, creditor, owner, member, shareholder or otherwise; provided, that the Competitive Business activities prohibited hereunder shall not include passive ownership of less than 5% of the stock of a privately-held or publicly-held
corporation. 

  

	 	d.	The Executive and the Company agree that should a “Change in Control” occur (as defined in section 12 of this Agreement), the restrictions contained in this Section 5 shall be in effect for only
60 days from the effective date the Change in Control occurs. 

 6. Confidential Information, Work Product;
Confidentiality of Terms. 
  

	 	a.	Executive shall keep secret and retain the confidential nature of all Confidential Information (as hereinafter defined) of or belonging to the Company or any of its Affiliates and take such other precautions with
respect thereto as the Company, in its sole discretion, may reasonably request. Executive shall not at any time, whether before or after the termination of his employment hereunder, use, copy, disclose, divulge or make available any Confidential
Information or Work Product to any natural person, partnership, limited liability company, corporation, trust, governmental body or any other legal entity; except that Executive may use, copy or disclose to any Person any Confidential Information
(i) to the extent required in the performance of his duties pursuant to this Agreement, (ii) to the extent it becomes publicly available through no fault of Executive, (iii) to the extent he is required to do so pursuant to applicable
law, court order and/or court-issued subpoena, or (iv) with the prior written consent of the Sole Director.

 EXECUTION VERSION 
  


	 	b.	Executive agrees, subject to applicable law, to treat the terms of this Agreement as “Confidential Information” and to not disclose or discuss or release any such terms to any Person (except to
Executive’s attorneys, accountants and other consultants who have agreed to keep such information confidential) without the consent of the Sole Director. 

  

	 	c.	If, during the employment relationship, Executive is engaged in or associated with the research, investigation, planning or implementation of any project, program or venture on behalf of or involving the Company, all
rights in the project, program or venture shall belong exclusively to the Company and shall constitute an opportunity belonging exclusively to the Company. Except as approved in advance and in writing by the Board of Directors of Kinex, Executive
shall not be entitled to any interest in such project, program or venture or to any commission, finder’s fee or other compensation in connection therewith, other than the compensation to be paid to Executive by the Company as provided herein.
Moreover, Executive hereby acknowledges that all Work Product is owned by the Company, and Executive covenants not to take any position or action contrary to such acknowledgement. 


 

	 	d.	All Confidential Information disclosed or made available by the Company or its Affiliates to Executive shall at all times remain the personal property of the Company or such Affiliates as the case may be, and all
documents, lists, plans, proposals, records, computer disks and other tangible items supplied to Executive that constitute or contain Confidential Information shall, together with all copies thereof, and all other property of the Company, be
returned to the Company immediately upon termination of employment for whatever reason or if sooner, immediately upon demand by the Company. 


7. Enforcement. 
  

	 	a.	Executive further acknowledges that the scope of the business of the Company and its Affiliates is independent of location in the Territory and that as a senior executive of the Company, Executive has and will have
direct and indirect responsibility, oversight and duties with respect to all of the businesses and enterprises of the Company and its controlled Affiliates and its and their current and prospective employees, vendors, customers, clients and other
business relations, and that, accordingly, the restrictions contained in Sections 5 and 6 are reasonable in all respects and necessary to protect the goodwill, Confidential Information, customer relationships and Work Product of the Company and its
Affiliates and that, without such protection, the Company’s and its Affiliates’ customer and client relations and competitive advantage would be materially adversely affected. It is specifically recognized by Executive that
(i) Executive is significantly responsible for the growth and development of the Company and its Affiliates and the creation and preservation of their goodwill, (ii) money damages are insufficient to protect such interests, (iii) such
prohibitions would be necessary and appropriate without regard to compensation being provided to Executive hereunder, and (iv) the Company would not enter into this Agreement with Executive without the restrictions contained in Sections 5
and 6. Executive further acknowledges that the restrictions contained in Sections 5 and 6 do not impose an undue hardship on him and that, since he has general business skills which may be used for a business other than a Competitive Business,
do not deprive Executive of his livelihood. Executive agrees that the covenants made in Sections 5 and 6 shall be construed as agreements independent of any other provision(s) of this Agreement and shall survive any order of a court of
competent jurisdiction terminating any other provision(s) of this Agreement.

 EXECUTION VERSION 
  


	 	b.	If, at the time of enforcement of Section 5 or 6, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the Parties agree that the maximum period, scope or
geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area. Because Executive’s services are unique and because Executive has access to Confidential Information, customers and Prospective
Customers of the Company and Work Product, and for the other reasons set forth herein, the Parties agree that money damages would not be an adequate remedy for any breach of this Agreement. Therefore, in the event of a breach or threatened breach of
any of Sections 5 or 6 of this Agreement, the Company and its successors and assigns shall, in addition to other rights and remedies existing in their favor, be entitled to obtain specific performance and injunctive or other relief in order to
enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security). To the fullest extent permitted by applicable law, in the event of a breach by Executive of Section 5 hereof, the Restricted Period shall
be tolled until such breach or violation has been duly cured. Executive agrees that the provisions of this Section 7 are reasonable and necessary to protect the Company. 


8. Notices. Any notice provided for in this Agreement shall be in writing and shall be either personally delivered, mailed by first
class mail (return receipt requested), or sent by overnight courier service: if to Kinex, to Kinex’s then-current headquarters, attention: Teresa Bair, Esq., SVP of Corporate Development and Legal Affairs, and if to Executive, to
Executive’s primary residence then on record with the Company (the Company shall be entitled to rely upon information provided by Executive from time to time concerning the address of Executive’s primary residence). Any notice under this
Agreement shall be deemed to have been given on the earlier of when so delivered or three (3) business days after being deposited in the mail (as the case may be). 

9. Cooperation; Return of Company Property. For a period of one (1) year following termination of Executive’s employment for
any reason, Executive agrees to cooperate in good faith with the Company and to be reasonably available to the Company with respect to continuing or future matters arising out of Executive’s services to the Company and its Affiliates in
exchange for compensation at an hourly rate of one hundred fifty dollars ($150.00), provided, however, that the Executive shall provide such cooperation at no additional charge to the Company during any periods in which Executive is receiving
compensation from the Company pursuant to Sections 4.b.iii., 4.d.ii., or 4.f. Upon termination, Executive shall promptly return to the Company all property of the Company and its Affiliates, whether tangible or intangible, which he possessed or
had control over at any time during the employment relationship, including, without limitation, credit cards, building and office access cards, keys, computer equipment, cell phones, electronic devices, manuals, files, documents, records, software,
customer database and other data, research, financial data and information, correspondence, statistics and payroll and other data, and any copies, compilations, extracts, excerpts, summaries and other notes thereof or relating thereto.

 PROPRIETARY RIGHTS AGREEMENT 

THIS PROPRIETARY RIGHTS AGREEMENT (this “Agreement”) is made and entered into as of June 1, 2015
(the “Effective Date”) by and between KINEX POLYMED HONG KONG LTD, a company organized and existing under the laws of Hong Kong, its subsidiaries, affiliates, successors or assigns (the
“Company”), and William Zuo, Ph.D. 
 In consideration of my employment, by the Company, I, William Zuo,
Ph.D., agree to the following as a further condition to my Employment Agreement with the Company, dated of even date herewith (the “Employment Agreement”): 

1. Inventions Retained and Licensed. I represent and agree that all inventions, original works of authorship, developments, concepts,
improvements, trade secrets, scientific know-how, and intellectual property specifically related to the manufacturing of pharmaceutical products or medical devices developed by me, in whole or in part, during
the term of my employment with the Company or any predecessor of the Company, under the scope of the terms and duties from the Employment Agreement, whether prior to, during or after the term of the Employment Agreement, whether patentable or not,
(collectively referred to as, “Inventions”) shall be assigned by me to the Company. If in the course of my employment with the Company, I incorporate into a Company product, process or machine or other Company document or material an
invention developed by me prior to my employment with the Company (“Prior Invention”) owned by me or in which I have an interest, the Company is hereby granted and shall have an exclusive, royalty-free, irrevocable, perpetual, worldwide
license to make, have made, modify, use and sell such Prior Invention as part of or in connection with the product, process or machine made by the Company. The provisions of this Section 1 will apply to all Inventions which are conceived or
developed during the term of my employment, whether before or after the date of this Agreement, and whether further development or reduction to practice may take place after my employment terminates. 

2. Assignment of Inventions. I agree that I will promptly make full written disclosure to the Company, will hold in trust for the sole
right and benefit of the Company, and hereby assign to the Company, or its designee, all my right, title, and interest in and to any and all Inventions, whether or not patentable or registrable under copyright laws, which I may solely or jointly
conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the period of time I am employed by the Company. I further acknowledge that all original works or authorship, etc., which are made by me
(solely or jointly with others) within the scope of and during the period of my employment with the Company and which are protectable by copyright are “works made for hire” as that term is defined under the United States Copyright Act.

 3. Maintenance of Records. I agree to keep and maintain adequate and current records of all Inventions during the term of my
employment with the Company. The records shall be in the form of notes, sketches, drawings, and any other format that may be specified by the Company. The records shall be available to and remain the sole property of the Company at all times.

 4. Patent and Copyright Restrictions. I agree to assist the Company, or its designee,
at the Company’s expense, in every proper way to secure the Company’s rights in any Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, including the
disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and
obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other
intellectual property rights relating thereto. I further agree that the foregoing obligation shall continue after the termination of my employment and/or of this Agreement. If the Company is unable because of my mental or physical incapacity, or for
any other reason, to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then I
hereby irrevocable designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for and, in my behalf and stead, to execute and file any such applications and to do all other lawfully
permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by me. 

5. Notification of New Employer. Upon leaving the employ of the Company for any reason, I hereby grant consent to the Company to notify
my new employer about my rights and obligations under this Agreement and the Employment Agreement, and I will furnish the Company with the name and address of my new employer, with respect to my next employment which occurs two (2) years
thereafter. 
 6. Term. The term of this Agreement shall be perpetual and shall survive termination of the Employment Agreement
regardless of the cause of termination of the Employment Agreement.
