Employee acknowledges and agrees that it is impossible to measure in money the damages which will accrue to SDSP if Employee breaches any of Employee's obligations under Sections 12, 13, 14 or 15 above, and that SDSP would be irreparably damaged by such breach by Employee. Accordingly, if any action or proceeding is instituted by or on behalf of SDSP to enforce such sections, Employee hereby waives any claim or defense thereto that SDSP has an adequate remedy at law or that SDSP has not been irreparably injured thereby. The rights and remedies of SDSP pursuant to this section are cumulative, and shall not exclude any other right or remedy SDSP may have pursuant to this Agreement or at law or in equity.
