Dear Sir/Madam,

In continuation to our letter dated April 28, 2021 with respect to Outcome of Board Meeting held on April 28, 2021, we wish to inform you that on account of the uncertainty created by an unprecedented second wave of the COVID-19 pandemic and the continued investments in R&D and Capex, the Board of Directors has decided it would not be appropriate to declare a dividend for FY21.

We would like to further inform that update on dividend was covered in our press release dated April 28, 2021.

Kindly take the above information on record and acknowledge.

Yours faithfully,
