Exclusive Manufacturing contract

We want a contract that will give exclusive rights to manufacture our product, where they buy a container from us and then sell the product with our brand, we receive 20% commission on all the products sold, 25% our own customers that purchase from them. They will be doing marketing to their own trade so marketing plan should be in the contract. We have a registration for design rights at the WIPO and they will be getting right to use our trademark.

We've attached a draft agreement that we will be ironing out in the coming week as points are discussed with the manufacturer
