Cancellation of Leave and License agreement as a Licensee

We entered an agreement for having office in Mumbai in anticipation that an Order for our Company will be coming to us which might require to have more number of employees to operate there in Mumbai. However the order is not granted to us and now the office which we agreed 4 months ago is now becoming burden on us. The owner insisting us to be there for 24 months as lock-in period mentioned therein. But, the cancellation clause also mentioned that, by giving one month notice one can cancel this agreement. In this case how should I approach to close this issue to get my Rental deposit back and to come out of this premises with good terms. We are getting messages from owner "to be there for 24 months or pay the damages for entire 24months". Lock-in period clause has "both the parties have agreed to set a lock-in period of 24 months during which neither the lecensor nor the licensee vacate the premises. If licensee leaves the premises for whatsoever reason, he shall pay to the Licensor license fee for the remaining lock-in period at the rate agreed upon in the agreement." Is it legally correct when we entered Leave and License agreement, and on top of that we lost our order which pushed us in deep trouble. It would be helpful If a draft letter be sent to the mentioned email id, if possible. Please help in this regard as we could not bare the rent as we did not get the contract, to pay the rent for remaining period of lock-in. (MUMBAI Location).
