normal   equitable   principles)  in  accordance  with  its  terms,   except  as
enforceability may be limited by bankruptcy, insolvency,  reorganization, debtor
relief or  similar  laws  affecting  the  rights  of  creditors  generally.  The
execution,  delivery and performance of this Agreement by the  Shareholder  will

other  agreement to which the Company or the  Shareholder is a party or by which
the Company or the Shareholder or their respective properties are bound.

                                 Indemnification

     4.1. Indemnification by the Shareholder.  In addition to any other remedies
available to Buyer under this Agreement, or at law or in equity, the Shareholder
shall  indemnify,  defend  and  hold  harmless  the  Company,  Buyer  and  their
affiliates  and their  respective  officers,  directors,  employees,  agents and
stockholders (collectively,  the ABuyer Indemnified Parties@),  against and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
liabilities,  recoveries,  suits,  causes of action and deficiencies,  including
interest,  penalties and reasonable fees and expenses of attorneys,  consultants
and experts  (collectively,  the ADamages@) that the Buyer  Indemnified  Parties
shall incur or suffer,  which arise,  result from or relate to any breach by the
Shareholder   of  (or  the  failure  of  the   Shareholder   to   perform)   his
representations, warranties, covenants or agreements in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Buyer by the Shareholder under this Agreement.

     4.2.  Indemnification by Buyer. In addition to any other remedies available
to the  Shareholder  under this Agreement,  or at law or in equity,  Buyer shall
indemnify,  defend and hold harmless the Shareholder against and with respect to

from or relate to any  breach of, or  failure  by Buyer 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 the
Shareholder by or on behalf of Buyer under this Agreement.

     4.3.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 4.1 or 4.2 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  Section  4.1 or  4.2  hereof,  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. Subject to
the following,  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.  The
indemnified  party is obligated to specify the basis of any  determination  that
counsel  selected  by  the  indemnifying  party  is  unsatisfactory  before  the
indemnifying  party shall be liable for attorney fees of counsel selected by the
indemnified  party.  The basis must be reasonable  and well grounded  before the
indemnifying  party shall be liable for the expenses of counsel  selected 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  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld  or  delayed,  unless the  indemnifying  party has refused to provide a
defense  against  such claim or action.  Likewise,  no  indemnified  party shall
consent to entry of  judgment or enter into any  settlement  of such claim where
the  indemnifying  party has refused to provide a defense  against such claim or
action until the indemnified  party has given the  indemnifying  party notice of
the terms of the judgment or settlement  and an  opportunity  to continue with a
defense if the judgment or settlement is unsatisfactory.
