PLAN FOR OT-101 IN THE UNITED STATES

This announcement is made by Ocumension Therapeutics (the "Company", together with its subsidiaries, the "Group") on a voluntary basis to keep the shareholders of the Company and potential investors informed of the latest business updates of the Group.

The board (the "Board") of directors of the Company is pleased to announce that the United States Food and Drug Administration (the "FDA") has recently granted approval for commencing the Initial Pediatric Study Plan (iPSP) for one of the Group's in-house developed key drug candidates, OT-101 (atropine 0.01%), a low-concentration (0.01%) atropine eye drop developed to retard, or slow down, the progression of myopia in children and adolescents, which represents an indication of FDA's authoritative recognition for the drug's safety.

Such recognition will also assist the Company in its application for phase III clinical trial of OT- 101 in China and Europe.

Cautionary Statement required by Rule 18A.05 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited: The Company cannot guarantee that it will ultimately commercialize OT-101(atropine 0.01%) successfully.
