contribute  to, and has not at anytime  sponsored,  maintained or contributed to
any  employee  benefit  plan which is or was  subject to any  provisions  of the
Employee Retirement Income Security Act of 1974, as amended. No employee benefit

supplier,  government employee or other person who is or may be in a position to
help or hinder the  profitable  use of the Assets or conduct of the Business (or
to assist Seller in connection with any actual or proposed transaction) which if
not  given  in the  past,  might  have  had a  material  adverse  effect  on the
profitable use of the Assets or conduct of the Business , or if not continued in
the future,  might materially  adversely effect the profitable use of the Assets
or conduct of the Business.

principally to the Assets.  This Agreement,  the Seller Agreements and the other
instruments  executed  by  Seller  or  Shareholders  and  delivered  to Buyer in
connection  herewith do not include any untrue  statement of a material  fact or
omit to state any material fact necessary to make the statements made herein and
therein not misleading in any material respect.

transactions   contemplated   hereby  have  been  carried  on  by  Seller,   the
Shareholders and their counsel directly with Buyer and its counsel,  without the
intervention  of any other  person  in such  manner as to give rise to any valid
claim against any of the parties hereto for a brokerage commission, finder's fee
or any similar payment.

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 or the  Shareholders  by or on behalf of Buyer
under this Agreement.




     5.3 Indemnification  Procedure.  If any party hereto discovers or otherwise
becomes aware of an  indemnification  claim arising under Section 5.1 or Section
5.2 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 5, 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.


                                   Article VI

                                  Miscellaneous

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.

     6.2  Entirety.  This  Agreement  embodies  the entire  agreement  among the

     6.4  Notices  and  Waivers.  Any  notice or waiver to be given to any party
