Answer: Yes, due to the action taken by the government it makes it difficult to perform under the contract.
Step-by-step explanation:
When the contract was signed by Putnam corporation and the pharmacies it was legal and valid contract. Due to the after effects of the pills sold by the pharmacies Food and Drug Administration has passed new regulations that the drug sold is illegal. The contract should also abide by the regulations passed by government authorities.
So the contract between the pharmacy and Putnam becomes void. The pharmacy chain is out of the contract and need not sell the drugs which are addictive and which has caused few deaths.
