for compensation, indemnity of payment to which it might otherwise be entitled
under the laws of any political entity in the event of or because of the
nonrenewal, expiration or termination of this Agreement for any reason, and
agrees further to indemnify and hold harmless NOV from any and all claims of
DISTRIBUTOR’s agents, officers or employees for similar compensation, indemnity
