Serving of Notice Period and Buyout

Hi, I have resigned from my current organization. I am ready to pay the buyout amount but current employer is not ready for my notice period buyout. In the agreement that I have signed has the following clause: "The Company or employee may, at any time during the course of the employment by stating their intention to do so in writing, terminate the employment by giving notice as given below or a salary payment in lieu of that notice. The Company may require an employee to complete all operative parts of the assignment or project he may be involved in on the date of resignation as determined by the Company before agreeing to his release. If, in exceptional cases, the Company agrees to an employee’s requests for an early release, the Company will recover the salary or part thereof equivalent to the balance notice period." Please guide me if it is possible for me to buyout the notice period ? I'm already serving notice period, and have informed about the buyout to the management.
