Remunaration to board of directors in pvt limited company

Hi,

My husband is BOD in 2 newly started private ltd companies having equal number of shares with other two BODs in the same companies.

My question is : -

Is there any restriction on the monthly remunaration paid to them from the above companies??

Further , out of total 3 BODs, two of them are actively involved in the business i.e. working as a whole time directors and involvement of the third BOD is very less, so is there any rule or a law for the remunaration to whole time directors in private limited companies apart from the share in the profit??????

And the last querry - in how many companies (private ltd) (in Maximum) , can person be a BOD ( Board of Directors)?? will it affect the remunaration received by them from these companies????

It will be of gr8t help if anyone can help me on this...its urgent!!

Regards

Jigna
