jointly  and  severally,  indemnify,  defend  and  hold  harmless  each  of  the
Shareholders  and the Seller and its officers,  directors,  employees and agents
against and with  respect to any and all  Damages  that such  indemnitees  shall
incur or suffer, which arise, result from or relate to any breach of, or failure
by Buyer or Key to perform any of its representations,  warranties, covenants or
agreements in this Agreement or in any schedule,  certificate,  exhibit or other
instrument  furnished  or  delivered  to  Seller by or on behalf of Buyer or Key
under this Agreement.

A. Indemnification Procedure. If any party hereto discovers or otherwise becomes
aware of an  indemnification  claim  arising  under  Section  6.1 or 6.2 of this
Agreement,  such indemnified party shall give written notice to the indemnifying
party, specifying such claim, and may thereafter exercise any remedies available
to such party under this Agreement;  provided,  however, that the failure of any
indemnified  party to give  notice as  provided  herein  shall not  relieve  the
indemnifying party of any obligations hereunder,  to the extent the indemnifying
party is not materially prejudiced thereby.  Further,  promptly after receipt by
an  indemnified  party  hereunder of written notice of the  commencement  of any
action or proceeding  with respect to which a claim for  indemnification  may be
made  pursuant to this Article 6, such  indemnified  party shall,  if a claim in
respect  thereof is to be made  against any  indemnifying  party,  give  written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld.


                                I. Miscellaneous

A. Survival of Representations,  Warranties and Covenants.  All representations,
warranties,  covenants and  agreements  made by the parties hereto shall survive
indefinitely without limitation, notwithstanding any investigation made by or on
behalf  of  any  of  the  parties  hereto.  All  statements   contained  in  any
certificate,  schedule,  exhibit or other instrument  delivered pursuant to this
Agreement  shall be deemed to have been  representations  and  warranties by the
respective party or parties,  as the case may be, and shall also survive without
limitation despite any investigation made by any party hereto or on its behalf.

A. Entirety. This Agreement embodies the entire agreement among the parties with
respect to the  subject  matter  hereof,  and all prior  agreements  between the
parties with respect thereto are hereby superseded in their entirety.

A.  Counterparts.  Any number of  counterparts of this Agreement may be executed
and each such counterpart shall be deemed to be an original instrument,  but all
such counterparts together shall constitute but one instrument.

A.  Notices and  Waivers.  Any notice or waiver to be given to any party  hereto
shall be in  writing  and  shall be  delivered  by  courier,  sent by  facsimile
transmission  or first class  registered  or certified  mail,  postage  prepaid,
return receipt requested.
