How to exit a limited term contract before the end

Hi Sir/ Madam.

I'm working as a civil engineer in Fujairah. I renewed my second visa on 26.05.2021.

I'm resigning from my job and submitted one month notice period, but my agreement is a limited period contract and mentioned that:

"Should either party desire to terminate the renewed contract, such party shall notify the other party of such desire within 3 months prior to the date of termination."

Such period shall be similar for both parties. Both parties agreed that the termination wage to be paid by the terminating party to the other party shall be equivalent to the value of the worker's total wage in 3 months.

Such wage shall be similar for both parties. But my company informed me to work for 90 days. Please give me some suggestions to leave easily from the company. I am ready to compensate the company for the remaining 2 month notice time.
