Barta entered into a written contract to buy the K&K Pharmacy, located in a local shopping center. Included in the contract was a provision stating “this Agreement shall be contingent upon Buyer’s ability to obtain a new lease from Landlord for the premises presently occupied by Seller. In the event Buyer is unable to obtain a lease satisfactory to Buyer, this Agreement shall be null and void.” Barta planned to sell “high-traffic” grocery items, such as bread, milk, and coffee, to attract customers to his drugstore. A grocery store in the shopping center, however, already held the exclusive right to sell grocery items. Barta, therefore, could not obtain a leasing agreement meeting his approval. Barta refused to close the sale. In a suit by K&K Pharmacy against Barta for breach of contract, who will prevail? Explain.
