John contacts the President of the Lohassel Magnet Company to purchase the magnets needed for the headphones. Lohassel and John enter into a contract in which John agrees to purchase 10,000 magnets per month at a cost of $6.00 each.

The contract is in writing and is for one-year. After one month of the contract, the President of Lohassle contacts John and says unfortunately, the company must raise the price of the contract to $7.00 each. John tells Lohassel's President that he has a valid enforceable contract.

Lohassel's President responds by stating that "we are a much larger company than your headphone company, we are also a subsidiary of the Good-Buy retail store chain, where you will be selling a large amount of your headphones. If you do not agree to pay $7.00 each, we will not ship the magnets and Good-Buy will never sell your headphones.

The ball is in your court." Reluctantly, John agrees to the higher price for the headphones for the remaining 11 months and signs a new amendment to the contract stating so.

a. Was there consideration for the second (amended) contract? Explain why or why not, and mention and explain what doctrine(s) may apply.

b. Also, can John get out of the second (amended) contract based on lack of consent? Explain why or why not, and mention and explain what lack of consent doctrine(s) may apply.
