in addition to the other remedies which may be available to it hereunder, file a
suit in equity to enjoin  Seller from such breach or threatened  breach.  If any
provisions  of this Section 8 are held to be invalid or against  public  policy,
the remaining provisions shall not be affected thereby. Seller acknowledges that
the  covenants  set forth in this Section 8 are being  executed and delivered by
Seller  in  consideration  of the  covenants  of  Purchaser  contained  in  this
Agreement,  and for other good and valuable  consideration,  receipt of which is
hereby acknowledged.

From  and  after  the date  hereof,  Seller  will  indemnify  and hold  harmless
Purchaser  against any claim,  loss,  liability or expense incurred by Purchaser
and arising out of or  attributable to any inaccuracy of any  representation  or
warranty or any breach of any covenant or agreement  made by Seller herein or in
any instrument or agreement referred to herein or contemplated hereby. Purchaser
will indemnify and hold harmless  Seller against any claim,  loss,  liability or
expense  incurred by Seller and arising out of or attributable to any inaccuracy

contemplated hereby. As used in this Section 9, "expense" shall include, without
