17. (a) The admitted and established facts are as under: ‘The execution of the exhibit A1-the agreement of sale between the plaintiffs on one hand and the defendants 1 and 2 on the other is admitted. The total sale consideration that was agreed to under exhibit A1 was Rs.3,02,40,000/-. Under exhibit A1, the plaintiffs had paid Rs.50 lakhs to the defendants 1 and 2 towards part of sale consideration. The plaintiffs had undertaken to pay the balance of sale consideration in two installments. Rs.1 Crore was agreed to be paid within a period of three months from the date of the agreement. The balance of Rs.1,52,40,000/- was agreed to be paid within three months from the above said payment. Thus, the total balance sale consideration of Rs.2,52,40,000/- was agreed to be paid within six months from the date of the agreement. In the event of the plaintiffs not being able to complete the final payment within six months from the date of the agreement, the defendants 1 and 2 had agreed to give them a grace period of additional three months. Thus, including the said grace period, the total time available to the plaintiffs to pay the balance of sale consideration is nine months from the date of the agreement. The plaintiffs had admittedly paid Rs.10,00,000/- only to the defendants 1 and 2 out of the 1st installment of Rupees one Crore that too on 18.08.1999 i.e., after the stipulated time of first three months.’ In this factual back drop, it is necessary to refer to the other relevant and important terms of the agreement of sale-exhibit A1.
