      HISTORY, REORGANIZATION AND CORPORATE STRUCTURE

OVERVIEW

      We are a leading provider of integrated non-vascular interventional surgical solutions in
China with a global vision. Since our inception in 2009, we have built up leading proprietary
technology platforms and developed economies of scale to become one of the few companies in
the world that is able to offer integrated solutions of endoscopes, active medical devices and
non-active consumables for all major medical specialties that perform non-vascular interventional
surgery, including urology, gastroenterology, hepatobiliary, respiratory, thoracic surgery,
otorhinolaryngology, gynecology and general surgery, according to CIC. According to the same
source, we have developed the most comprehensive portfolio of medical devices for non-vascular
interventional surgeries in urology globally and in China.

     Mr. Yan first joined our Company in July 2012 as the general manager and he was
subsequently appointed as a Director in April 2014. Mr. Yan has been responsible for the overall
management of the Company since his joining. In December 2014, Mr. Yan acquired an aggregate
of approximately 59.7% of the total issued share capital in the Company from certain of our then
equity owners, and has become our Controlling Shareholder since then. It was the time when Mr.
Yan first invested in our Company.

      Our Company was established in Shanghai as a limited liability company in February 2009
by Innovex Medical Limited, a company owned by an Independent Third Party. On its
establishment, the Company was principally engaged in R&D, manufacture and sale of medical
devices. Before Mr. Yan’s joining, our Company was in its early stage development, and has
relatively limited pipeline products of four Class II medical devices.

      Mr. Yan accumulated abundant experience in business management in his early stage of
career possessing strong business acumen. During the period when Mr. Yan served as a senior
management in our Company from 2012 to 2014, he saw into the unmet medical needs in the PRC
and therefore a potential huge market for medical devices. Mr. Yan acquired the controlling
interests in our Company in December 2014. As of the Latest Practicable Date, Mr. Yan was
entitled to exercise or control the exercise of the voting rights attaching to approximately 63.4% of
the shareholdings in our Company.

     After Mr. Yan’s joining, he has been taking lead in steering the development of our Company,
and our R&D has undergone rapid development under Mr. Yan’s leadership. In April 2019, we
commenced the registrational clinical trial for our Core Products, a single-use electrosurgical snare
and a plasma radio frequency generator, and submitted the applications for Class III medical
device certificate to the NMPA in August 2021. To date, we had 31 products approved in China,
the U.S., the EU and/or Japan, and 17 products under development.

         including but not limited to progress in the R&D of our product candidates, commercialization and expansion, and
         achievements in our operational and financial performance, in particular, (a) the increase of valuation of the

         products and the commercialization of our percutaneous renal puncture kit and airway balloon dilation catheter in
         the PRC; (b) the increase of valuation of the Company from the Series B1 Financing to Series B2 Financing was
         due to the launch of R&D of our Core Products in August 2019 and the commercialization of our ureteral occlusion
         catheter, single-use nasobiliary drainage catheter, ureteral access sheath, single-use stone retrieval basket, fiber
         ureterorenoscope in the PRC; and (c) the valuation of Series C1 Financing and Series C2 Financing was determined

         single-use nasobiliary drainage catheter, single-use stone extraction balloon, dilation balloon catheter, negative
         pressure drainage device and single-use ureterorenoscope from the NMPA and thereby further expanded our sales
         and marketing.
