Firstly, I would like to know what the clause really means, in plain English.

Secondly, like most limited company directors I receive dividends and salary from my company and also claim expenses. Given that the vast majority of my company's income is from the above client, does this clause restrict the way my company is allowed to distribute its income to shareholders and directors? If I take dividends then will I be in breach of my client's contract?

Thanks
