activities, analyses, including but not limited to design drawings, interface drawings, manuals and stress analysis reports, relating to the design, engineering of the Target Products. 

Section 2. ASSIGNMENT 
 2.1 The Proprietor hereby assigns and transfers to Recipient all rights and title (free and clear of any lien, claim, restriction, charge, security interest or other encumbrance) possessed by Proprietor
in respect of the Information and the full unfettered and exclusive worldwide right to use the Information for any purpose whatsoever (including the filing of patent applications in respect of all or any aspect of it). 

2.2 The Recipient reserves the right to assign all of its rights, benefits and obligations under this Agreement to any of its Affiliates.

 Section 3. CONSIDERATION 

3.1 Assignment Fee 
 The Recipient shall pay an assignment fee of up to US$2,000,000 or RMB equivalent based on the Earn Out Revenue: 
 (a) The Recipient shall pay US$1,000,000 or RMB equivalent if the Earn Out Revenue of the existing Target Products reaches US$2,100,000 during the 18 months immediately following the Closing. If the Earn
Out Revenue is less than US$2,100,000, such payment shall be reduced proportionally for any shortfall of the Earn Out Revenue. 

(b) The Recipient shall pay the remaining US$1,000,000 or RMB equivalent if the Earn Out Revenue of the existing Target Products, and any
other products considered applicable by the Recipient, reaches an additional US$2,100,000 during the 18 months immediately following the Closing. If the Earn Out Revenue is less than US$4,200,000 but greater than US$2,100,000, such payment of the
remaining US$1,000,000 or RMB equivalent shall be reduced proportionally for any shortfall of the Earn Out Revenue. 
 3.2
Determination of Earn Out Revenue 
 (a) For the purpose of the Recipient to calculate the Earn Out Revenue, the Recipient shall
as promptly as practicable provide the Proprietor with a written statement of its calculation (the “Calculation Statement”) of the Earn Out Revenue for the relevant period(s). 

(b) Upon receiving a Calculation Statement, the Proprietor shall within ten (10) days either (i) notify the Recipient in
writing that it agrees with the Calculation Statement or (ii) notify the Recipient in writing that it does not agree with the Calculation Statement and stating the grounds of their disagreement and their own calculation of the Earn Out Revenue
for determination of the relevant part of the applicable assignment fee, together with a copy of any information used in making such calculation (the “Dispute Notice”). If the Recipient does not receive any Dispute Notice from the
Proprietor within such ten (10) days period, the Proprietor shall be deemed to have agreed to the Calculation Statement and the Recipient’s calculation of the Earn Out Revenue for determination of the relevant part of the applicable
assignment fee. 
 (c) In the event a Dispute Notice is given by the Proprietor according to Section 3.2(b), the
Proprietor and the Recipient shall meet and attempt in good faith to resolve the items or amounts in dispute (the “Disputed Portion”). If the Proprietor and the Recipient are unable to reach an agreement within twenty (20) days
after receipt of the Dispute Notice by the Recipient, the Proprietor or the Recipient may request an Independent Advisor to review the Disputed Portion and compute the Earn Out Revenue for the relevant period(s) in question. In making its
calculation, the Independent Advisor shall consider only the Disputed Portion (and to the extent required, any other items or amounts necessary to derive the Disputed Portion). Such determination shall be made within twenty (20) days after such
request and shall be conclusive and binding on the Parties. The fees, costs and expenses of the Independent Advisor shall be borne by the Party whose calculation of the Earn Out Revenue for the relevant period(s) is furthest from the Independent
Advisor’s calculation. 

 (d) For the avoidance of doubt, before the Disputed Portion is finally determined pursuant
to this Section 3, the Recipient shall have the right (but not the obligation) to pay to the Proprietor the undisputed portion of the Earn Out Revenue proportionally. 

Section 4. FURTHER ASSURANCE 
 4.1 The Proprietor agrees to disclose all the Information known to the Proprietor to the Recipient, or any person nominated by the Recipient, and provide all other reasonable assistance and information,
including but not limited to all the Technical Documentation, as may be reasonably necessary in order to assist Recipient, or its nominee, to develop, use and/or manufacture the Targeted Products. 

4.2 The Proprietor agrees that from the date of this Agreement, without the prior written consent of the Recipient, not: 

(a) to communicate or otherwise make available the Information to any third party; and/or 

(b) to use the Information for any purpose. 
 4.3 The Proprietor undertakes that it shall not and shall procure the IGC Holders (as defined in the Lease Agreement) not to, participate, assist, be concerned with, engaged or interested in, any business
or entity in any manner, directly or indirectly, which is in competition with any business activities (including but without limitation, research and development, manufacturing, the sale and distribution) in connection with the Target Products in
the PRC or any other jurisdiction. 
 4.4 If the Information disclosed by the Proprietor to the Recipient is not sufficient to
enable the applications and/or manufacture of the Targeted Products properly, efficiently and in reasonable quantities, The Recipient may serve notice on the Proprietor to that effect, identifying the areas of deficiency in the Information
disclosed. Should the Proprietor, in the reasonable opinion of the Recipient, fail in the four (4) week period following service of such notice to remedy such deficiencies, the Recipient may serve notice on the Proprietor requiring the payment
of the sum identified in Section 3, and the Proprietor agrees to repay this sum within two weeks of receipt of such notice for payment. 
 Section 5. REPRESENTATIONS AND WARRANTIES

claims by a third party based on any facts which if substantiated would constitute such a breach. The Proprietor further agrees that the Recipient’s indemnification under this Section would first come from the assignment fee (if any is
