If lessor so terminates this lease, lessor may, if it elects, enter into a new lease covering the premises with the intended assignee or sublessee on such terms as lessor and such person may agree or enter into a new lease covering the premises with any other person; in such event, lessee shall not be entitled to any portion of the profit, if any, which lessor may realize on account of such termination and reletting. From and after the date of such termination of this lease, lessee shall have no further obligation to landlord under this lease, except for matters occurring or obligations arising under this lease prior to the date of such termination.
