Confusion in Indemnity Clause in the offer letter.

Here's the exact text of the clause copied from offer letter, "[Company A] will be investing considerable sums of money in training and enhancing the skill sets of the Employee. In consideration of the training and enhancement of skill sets that the Employee will receive from the Company, the Employee agrees to serve in the employment of the Company for a minimum period of 18 Months from the date of execution of the Employment Agreement. Accordingly, if the Employee (i) fails to complete the Minimum Term; and/or (ii) fails to perform his/her obligations under the Employment Agreement, the Employee shall pay the Company a sum of Rs. 2,50,000/- (Rupees Two Lakh Fifty Thousand only) as liquidated damages suffered by the Company thereof." I have accepted the offer letter from [company A] but I have recieved another offer from [company B] and I want to join company B. Will I have to pay bond money if I don't join company A now as I have already accepted the offer letter.
