reason that the Intellectual Property, is or could be, invalid or unenforceable,
including,  but not  limited to, the failure of Seller to timely pay any fees or
dues associated with the Intellectual Property. To the best knowledge of Seller,
no Actions or Proceedings are pending or threatened, questioning the validity or
effectiveness  of  any  Intellectual   Property  or  asserting  that  Seller  is
infringing or otherwise adversely affecting the rights of any Person with regard
to any intellectual  property of such Person.  The Intellectual  Property is not
being  infringed  by any Person and  Seller,  to the best of his  knowledge,  is
unaware of any potential  infringement of the  Intellectual  Property.  No third
party  intellectual  property  will be  infringed  as a result of the use of the
Assets.  There are no royalties,  fees or other amounts  payable by or to Seller
with  respect  to any of the  Intellectual  Property.  The  consummation  of the
transactions  contemplated  by this Agreement and the Seller  Documents will not
result in the loss of any Intellectual Property or rights therein.

effect,  will  continue  to be in full force and effect  after the  Closing  and
Seller is not  aware,  or could  not be  reasonably  aware,  of any  pending  or

without limitation,  products liability claims) or the transactions contemplated
hereby,  at  law  or in  equity  or  before  or by any  Governmental  Entity  or
arbitrator,  which has had or could have a material  adverse affect on Purchaser
or the Assets, and, to the best knowledge of Seller, there is no valid basis for
any such  Action or  Proceeding.  Except as set  forth on  Schedule  3.10 of the
Disclosure Schedule, there is no pending or threatened Action or Proceeding that

in connection with the consummation of the transactions  contemplated  hereby or
thereby.  Seller  is not  subject  to any  Laws  or,  to the  best  of  Seller's
knowledge,  any proposed  Laws,  which has had or could have a material  adverse
affect on the Assets or on Purchaser's  ability to manufacture any products from
the Patents or Technology.

conducting  all research,  development,  manufacture,  and sales relating to the
Assets,  and all products  resulting  from the Patents or  Technology  have been
provided, developed, marketed and sold in compliance with all applicable Laws of
Governmental  or Regulatory  Authority.  Seller has not received  notice of, and
does not have knowledge of any such violation or alleged  violation with respect

                  (b) The  parties  hereto  recognize  that the Laws and  public
policies  of the  various  states  of the  United  States  may  differ as to the
validity  and  enforceability  of  covenants  similar to those set forth in this
Section.  It is the intention of the parties that the provisions of this Section
be enforced to the fullest  extent  permissible  under the Laws and  policies of
each   jurisdiction  in  which   enforcement   may  be  sought,   and  that  the
unenforceability  (or the  modification  to conform to such Laws or policies) of
any provisions of this Section shall not render  unenforceable,  or impair,  the
remainder of the  provisions of this Section.  Accordingly,  if any provision of
this Section shall be determined to be invalid or unenforceable, such invalidity
or unenforceability  shall be deemed to apply only with respect to the operation
of such provision in the particular  jurisdiction in which such determination is
made and not with respect to any other provision or jurisdiction.

                  (c) The parties hereto  acknowledge  and agree that any remedy
at Law for any breach of the provisions of this Section would be inadequate, and
Seller  hereby  consents to the granting by any court of an  injunction or other
equitable relief, without the necessity of actual monetary loss being proved, in
order that the breach or threatened breach of such provisions may be effectively
restrained.

covenant or  agreement on the part of Seller  contained in this  Agreement or in
the Seller Documents;

                  (b) the Retained Liabilities;

connection with:

                  (a) Purchaser's    misrepresentation,    breach    of   any

to perform any covenant or agreement on the part of Purchaser  contained in this
Agreement;

                  (b) the Assumed Liabilities; or

         10.04 Notice and Defense of a Claim. If either party shall be presented
with or have actual notice of a claim against it which gives or may give rise to
an Indemnified Liability, then the party


                                      -28-





entitled to  indemnification  (the  "Indemnified  Party") shall notify the other
(the "Indemnifying Party") in writing thereof (in accordance with Section 12.01)
within thirty days of notice of a claim,  otherwise the Indemnified  Party shall
waive its right to seek indemnification  hereunder.  The Indemnifying Party may,
at its expense,  vigorously and diligently prosecute, defend and settle any such
claim;  and if the  Indemnifying  Party  assumes such defense it will notify the
Indemnified  Party  thereof,  and thereafter  the  Indemnifying  Party will not,
except as provided  below,  be obligated to pay any expenses of the  Indemnified
Party (including but not limited to, legal fees and  disbursements,  court costs
and the cost of appellate  proceedings) in connection with such claim, provided,
however,  that the  Indemnified  Party may,  at the sole cost and expense of the
Indemnified Party, at any time prior to the Indemnifying Party's delivery of the
notice referred to above, file any motion, answer or other pleadings or take any
other action that the Indemnified  Party reasonably  believes to be necessary or
appropriate to protect its interests.  The  Indemnified  Party will cooperate in
the defense of any such  claim,  and the  Indemnifying  Party will pay any costs
incurred by the Indemnified Party in connection therewith. The Indemnified Party
will not  settle  any  claims  for  which the  Indemnifying  Party may be liable
without  the prior  written  consent of the  Indemnifying  Party  unless (i) the
Indemnified  Party releases the Indemnifying  Party from all of the Indemnifying
Party's  obligations to the Indemnified Party with respect to the claim, or (ii)
the Indemnifying  Party is in default in its obligations under this Section.  In
the case of a  settlement  pursuant to item (ii),  the  Indemnifying  Party will
promptly pay to or in accordance with the instructions of the Indemnified  Party
any amount payable pursuant to such settlement.  Notwithstanding  the foregoing,
if both the Indemnifying Party and the Indemnified Party are named as parties or
subject to any claim and either such party determines with advice of counsel and
in its  reasonable  discretion  that  there  may be one or more  legal  defenses
available to it that are different from or additional to those  available to the
other  party or that a conflict of interest  between  such  parties may exist in
respect of such  claim,  then the  Indemnifying  Party may decline to assume the
defense on behalf of the Indemnified  Party or the Indemnified  Party may retain
the defense on its own behalf,  and, in either such case,  after  notice to such
effect is duly given to the other party (in accordance with Section 12.01),  the
Indemnifying  Party shall be relieved of its obligation to assume the defense on
behalf of the Indemnified Party, but shall be required to pay any legal or other
expenses,   including  without  limitation,   reasonable   attorneys'  fees  and
disbursements, incurred by the Indemnified Party in its defense.

Seller and Purchaser;

                  (b) at any time before the Closing, by Seller or Purchaser, in
the event (i) of a material breach hereof by the  non-terminating  party if such
non-terminating party fails to cure such

                                      -29-





breach within five Business Days following written  notification  thereof by the
terminating party or (ii) upon written notification of the non-terminating party
by  the  terminating  party  that  the  satisfaction  of  any  condition  to the
terminating  party's  obligations  under this Agreement or the Seller  Documents
becomes  impossible or  impracticable  with the use of  commercially  reasonable
efforts if the  failure of such  condition  to be  satisfied  is not caused by a
breach hereof by the terminating party; or

                  (c) at any time after  March 15,  1999 by Seller or  Purchaser
upon written notification to the non-terminating  party by the terminating party
if the Closing  shall not have  occurred on or before such date and such failure
to  consummate  is not  caused  by a  breach  of this  Agreement  or the  Seller
Documents by the terminating party.

         11.02    Effect of Termination.

                  (a) If this  Agreement  and the Seller  Documents  are validly

obligation  on the part of  Seller  or  Purchaser  (or any of  their  respective

than Seller's  material  breach or failure to satisfy a condition,  Seller shall
refund the $50,000  due  diligence  deposit  paid by  Purchaser  pursuant to the
letter  agreement  between the parties dated  November 23, 1998. In the event of
any  termination,  the  provisions  with respect to "Expenses" in Section 12.05,
"Entire Agreement" in Section 12.06 and  "Confidentiality" in Section 12.12 will
continue to apply following any such termination.

                  (b)  Notwithstanding  any other provision in this Agreement to
the contrary, upon termination of this Agreement pursuant to Section 11.01(b) or
(c),  Seller will remain liable to Purchaser for any breach of this Agreement by
Seller  existing  at the time of such  termination,  and  Purchaser  will remain
liable to Seller for any breach of this  Agreement by Purchaser  existing at the
time of such  termination,  and  Seller or  Purchaser  may seek  such  remedies,
including  damages and fees of attorneys,  against the other with respect to any
such breach as are provided in this  Agreement or as are otherwise  available at
Law or in equity.

                  (e) Each party hereby consents and agrees that the federal and
state courts located in New York,  New York each shall have  exclusive  personal
jurisdiction and proper venue with respect to any such action seeking injunctive
or similar relief hereunder.  In any dispute between the parties,  neither party

any such court as an  inconvenient  forum.  Each party  hereby  waives  personal
service of any summons,  complaint or other  process,  which may be delivered by
