Preincorporation contrat

Hi,

As we know contracts made in behalf of the Company before its incorporation are called Pre-incorporation Contracts, Generally these contracts cannot bind the company subject to the exemption under section 15 and 19 f d Special Relief Act 1963,

One f our Client has entered into Pre- incorporation and is eligible for the exemption so provided, can anyone please help me about,

1. The Proedure for ratification by the Company,

2. How to communicate such acceptance with the other party. Please provide if there s any Specific       Format for such acceptance.

Thanks for your Patience.
