Answer to q. no 5:
As per the written compensation plan, Duncan can establish the contract as implied as the conditions tells that Mitsui will forward some benefit in lieu of service extended to them by Duncan. He had done his part but Mitsui denied compliance their written commitment. An implied contract is such contract which enforces both the party with acceptance of benefit knowingly to one party by another party not to be considered as gift and obviously with the consideration value (Smith, 2011).
The consideration value must be fair value of the effort by one party and that is in lieu of the benefit received. In this case Duncan had offered his effort for the performance of Mitsui and had made substantial effect on the performance of the company on the understanding of getting the compensation as per the contract signed by both Duncan and Mitsui. The denial on the part of Mitsui generates the situation of violation of implied contract.
