The penalty for early termination of tenancy

Sir, I have taken an office in Dubai for three years starting from 1st April 2015 to 31st March 2018. Due to slow business conditions, I am forced to reduce expenses and planning to vacate current office and move to a smaller one. Unfortunately, there is no early termination clause in the lease agreement.

Please advise what is the penalty in such cases as per government law.

Thanking You, Kind Regards.... Kuttan
