        11.   Subsequent Subleases, Assignments and Modifications. Sublessee shall not further sublet the Premises or any portion thereof, nor assign, amend or modify this Sublease, without the express prior written consent of Sublessor, which consent may be withheld by Sublessor in its sole and absolute discretion.. Any attempted further subletting of the Premises or assignment, amendment or modification of this Sublease without the express prior written consent of Sublessor shall be void ab initio and shall constitute a material default by Sublessee under this Sublease.

        12.   Attorneys' Fees. In the event suit is brought to enforce or interpret any part of this Agreement, the prevailing party shall be entitled to recover as an element of his costs of suit, and not as damages, reasonable attorneys' fees to be fixed by the court.
