                                 ---------------

6.1      The Company and Seller do, jointly and  severally,  and hereby do agree
         to, indemnify and hold harmless the Purchaser (which includes,  for the
         purposes of this  Article,  Purchaser's  officers  and  directors,  and
         shareholders)  against any Losses, joint or several, to which Purchaser
         may become  subject  under the Exchange  Act, any state or federal law,
         statutory or common law, or otherwise,  insofar as such losses, claims,
         damages or liabilities (or actions or proceedings, whether commenced or
         threatened,  in respect  thereof)  arise by reason of the inaccuracy of
         any  warranty or  representation  contained in this  Agreement,  or any
         omission or alleged  omission to state therein a material fact required
         to be stated  therein or necessary to make the  statements  therein not
         misleading,  and the  Company  and Seller  will in  addition  reimburse
         Purchaser for any legal or any other  expenses  reasonably  incurred by
         Purchaser in connection with  investigating or defending any such loss,
         claim, liability,  action or proceeding. Such indemnity shall remain in
         full force and effect  regardless  of any  investigation  made by or on
         behalf  of  Purchaser  and  shall  survive  the sale of the  Shares  to
         Purchaser.  As used herein,  "Losses"  means any loss,  claim,  damage,
         award,  liabilities,  suits,  penalties,  forfeitures,  cost or expense
         (including, without limitation,  reasonable attorneys',  consultant and
         other  professional  fees and  disbursements of every kind,  nature and
         description).

         to this Agreement.  The parties agree that any service of process to be

         all of which together shall constitute one and the same instrument.

         documentation  necessary to prove the proper amount to withhold of such
         taxes  and to  prove  payment  to the tax  authority  of such  required
         withholding.

9.6      Waivers  and  Amendments;  Non-Contractual  Remedies;  Preservation  of
         Remedies.  This  Agreement  may  be  amended,  superseded,   cancelled,
         renewed,  or extended,  and the terms  hereof may be waived,  only by a
         written instrument signed by authorized  representatives of the parties
         or, in the case of a waiver,  by an  authorized  representative  of the
         party waiving compliance. No such written instrument shall be effective
         unless it expressly  recites  that it is intended to amend,  supercede,
         cancel,  renew or extend this Agreement or to waive compliance with one
         or more of the terms  hereof,  as the case may be. No delay on the part
         of any  party  in  exercising  any  right,  power  or  privilege  shall
         hereunder  shall operate as a waiver  thereof,  nor shall any waiver on
         the part of any party of any such  right,  power or  privilege,  or any
         single or  partial  exercise  of any such  right,  power of  privilege,
         preclude  any  further  exercise  thereof or the  exercise of any other
         right, power or privilege.  The rights and remedies herein provided are
         cumulative  and are not  exclusive  of any rights or remedies  that any
         party may otherwise  have at law or in equity.  The rights and remedies
         of any party based upon,  arising out of or otherwise in respect of any
         inaccuracy in or breach of any  representation,  warranty,  covenant or
         agreement contained in this Agreement shall in no way be limited by the
         fact that the act,  omission,  occurrence  or other state of facts upon
         which any claim of any such  inaccuracy  or breach is based may also be
         the  subject  of  any  other  representation,   warranty,  covenant  or
         agreement  contained  in  this  Agreement  (or in any  other  agreement
         between the parties) as to which there is no inaccuracy or breach.
