To,

The Company Secretary & Members of the Board Subex Limited

Dear All,

I tender my resigna�on from the posi�on of Independent Director of the Company, with immediate effect. This decision has emanated from the concern that most of the directors (including me) have no knowledge of the IT industry, as expressed by our shareholders at the AGM this morning.

I take this opportunity to thank the Board of Directors for their con�nued support and guidance during my tenure and wish Subex every success in the future.

Yours Sincerely, Poornima Prabhu

G'Evening Ramu, Nisha and Members of the Board,

I would like to tender my resignation as an Independent Director of Subex Limited.

This is the outcome of a lack of confidence in the ability and experience of the Board expressed by shareholders at the Annual General Meeting held earlier today.

It has been my privilege to serve on the Board of the organisation. I thank the Chairman, Members of the Board and the leadership team of Subex for their support.

Thank you.

Archana
