Unclear Notice period condition by Employer

Hi Team, I have below condition in my appointment letter regarding service termination, I believe to have notice period of 30 days but my organization is forcing me to put notice of 90 days. Can you advise if organization can legally ask me to serve notice more than 30 days with below clauses agreed. " 6. Termination and Suspension The Company may terminate the services of the Employee at any time, with or without assigning reasons, by prior notice in writing of thirty days or pay in lieu thereof, including for unsuitability for the Employee’s role and responsibilities or for failure to meet performance levels. The Employee may terminate his/her services at any time by prior notice in writing of thirty days. Unless accepted by the Company the Employee shall not be entitled to terminate this Agreement by paying salary in lieu of notice, it being understood that the notice period is meant for a smooth and complete handover of responsibilities. The Company may however waive its right to notice in whole or in part in which case the Employee shall have no right to any salary for the notice period so waived by the Company. Notwithstanding the foregoing, if the Company is of the opinion that an Employee is discharging responsibilities of crucial importance, the Company shall, at a time it deems fit, intimate the Employee in writing that he/she shall give such longer notice that the Company deems fit, which in any case shall not exceed 90 days." I hold an offer but it is required to join the new organization within 30 days, and service/experience letter is mandatory to submit. Thanks in advance for help. Regards, Nitesh
