Notice for non-renewal of the lease contract by the tenant

Dear lawyer,

I have a tenancy contract for one year in Dubai, ending on 25 November 2018.

On the 8th of October, the landlord sent me a lease renewal, with some parts of the contract modified and contains different terms from the previous one.

I decided I don't want to renew the contract; neither with the new nor old conditions. On the 1st of November, I notified the landlord that I will vacate on the current contract end date 25 Nov.

He replied that I needed to notify him 90 days prior to the expiry date and I didn't, and now he is entitled to reimbursement and asks for 2 months' rent as a compensation.

Our contract says only "Tenant agrees to notify the Landlord in writing 3 months (90 days) prior to the expiry of this Agreement of his intention to renew or not renew the Agreement".

However, no financial penalties for breaking the clause of 90 days' notice of non-renewal are mentioned there.

Please tell, can he claim from me this 2 months' amount?

I will highly appreciate your opinion.

Best regards
