1) Termination of the existing share option scheme. 2) Proposed adoption of a new share option scheme. 3) Convening of an Extraordinary General Meeting (EGM), accompanied by a form of proxy for voting purposes.

The full English and Chinese versions of the circular, the EGM notice and the proxy form are now accessible on the company’s website (www.uni-bioscience.com) and on the HKEX website (www.hkexnews.hk). Registered shareholders are encouraged to review these materials online.
