     any third party unless (i) disclosure is ordered by a court of competent
     jurisdiction, after all appropriate appeals to prevent disclosure have been
     exhausted and (ii) Seller gave Purchaser prompt notice upon learning that
     any third party sought or intended to seek a court order requiring the
     disclosure of any such portion of the Prosecution History File. In
     addition, Seller will continue to prosecute, maintain, and defend the
     Patents at its sole expense until the Closing.

          (c) Seller will also, at the reasonable request of Purchaser after

date or final deadline for payment of such fee would be after the Closing.

     5.3 FOREIGN ASSIGNMENTS. To the extent the Patents include non-United
States patents, Seller will deliver to Purchaser's representatives executed

6.   REPRESENTATIONS AND WARRANTIES OF SELLER

Seller hereby represents and warrants to Purchaser as follows that, as of the
Effective Date and as of the Closing:

     6.1 AUTHORITY. Seller is a company duly formed and validly existing under
the laws of State of Israel. Seller has the full power and authority and has
obtained all third party consents, approvals, and/or other authorizations
required to enter into this Agreement and to carry out its obligations
hereunder, including, without limitation, the assignment of the Assigned Patent
Rights to Purchaser.

     6.2 TITLE AND CONTEST. Seller owns all right, title and interest to the
Assigned Patents Rights, including, without limitation, all right, title and
interest to sue for infringement of the Patents. To Seller's knowledge, the
Assigned Patent Rights are free and clear of all liens, claims, mortgages,
pledges, security interests or other encumbrances and restrictions of any kind
whatsoever. The Seller is not aware of any actions, suits, investigations,
claims or proceedings that are either pending or in progress, in each case
relating in any way to the Assigned Patent Rights. The Seller is not party to
any contract, agreement, option, commitment, proposal, bid, offer, or right
with, to, or in any person to acquire any of the Assigned Patent Rights.

     6.3 GOVERNMENT FINANCING. Except with respect to certain financing provided
by the Office of the Chief Scientist of the Ministry of Industry, Trade and
Labor of the State of Israel, none of the research and development that led to
the inventions which are the subject of the Assigned Patent Rights and none of
the technology or know-how incorporated in those inventions were financed by any
governmental institution.

     6.4 EXISTING LICENSES AND OBLIGATIONS. There is no obligation imposed by a
standards-setting organization to license any of the Patents on particular terms
or conditions. Except for the license granted by Purchaser to Seller pursuant to
a separate agreement between the parties, (a) no licenses under the Patents have
been granted to or retained by Seller and (b) after Closing, none of Seller, any
prior owner, or any inventor will retain any rights or interest in the Assigned
Patent Rights. To the Seller's knowledge, no licenses under the Acquired Patents
have been granted to or retained by any prior owner or any inventor. No licenses
under the Patents (excluding the Acquired Patents) have been granted to or
retained by any prior owner or any inventor.


                                     Page 6
<PAGE>


     6.5 RESTRICTIONS ON RIGHTS. Purchaser will not be subject to any covenant
not to sue or similar restrictions on its enforcement or enjoyment of the
Assigned Patent Rights or the Abandoned Assets as a result of any prior
transaction related to the Assigned Patent Rights or the Abandoned Assets to
which Seller, Seller's affiliates, or any inventor is a party. To Seller's
knowledge, Purchaser will not be subject to any covenant not to sue or similar
restrictions on its enforcement or enjoyment of the Assigned Patent Rights or
the Abandoned Assets as a result of any prior transaction related to the
Assigned Patent Rights or the Abandoned Assets to which any non-inventor
assignor to Seller or Seller's affiliates is a party.

     6.6 VALIDITY AND ENFORCEABILITY.

          (a) None of the Patents or the Abandoned Assets (other than Abandoned
     Assets for which abandonment resulted solely from unpaid fees and/or
     annuities) has ever been found invalid, unpatentable, or unenforceable for
     any reason in any inter partes administrative, arbitration, judicial, or
     other proceeding.

          (b) To the best of Seller's knowledge, Seller has not received any
     notice or information of any kind from any source suggesting the
     invalidity, unpatentability, or unenforceability of any claimed subject
     matter within the Patents or Abandoned Assets that has ultimately been
     allowed, granted, or otherwise deemed patentable by a respective patent
     authority or patent office, with the exception of (i) rejections,
     objections, or other deficiencies identified by such patent authority or
     patent office which were overcome to result in the allowance, grant, or
     patenting of such claimed subject matter and (ii) any documents relating to
     the examination or consideration by a patent office or patent authority of
     any of the patents or patent applications listed in Exhibit G.

          (c) To the best of Seller's knowledge, Seller has not received any
     notice or information of any kind from any source suggesting the
     invalidity, unpatentability, or unenforceability of claims contained within
     any of the patent applications within the Patents that have not yet been
     subject to substantive examination by a respective patent office or patent
     authority.

          (d) If any of the Patents is terminally disclaimed to another patent
     or patent application, all patents and patent applications subject to such
     terminal disclaimer are included in this transaction.

          (e) To the extent "small entity" fees were paid to the United States
     Patent and Trademark Office for any Patent, such reduced fees were
     appropriate at the time of such payment because the payor qualified to pay
     "small entity" fees and specifically had not licensed rights in any Patent
     to an entity that was not a "small entity."

     6.7 CONDUCT. Seller has not, and to Seller's knowledge, no prior owner(s),
nor their respective agents or representatives, have engaged in any conduct, or
omitted to perform any necessary act, the result of which would be reasonably
expected to invalidate any of the Patents or hinder their enforcement,
including, without limitation, misrepresenting the Patents to a standard-setting
organization.

     6.8 ENFORCEMENT. In connection with the process relating to the sale of the
Patents, the Seller has prepared an analysis showing certain potential
infringements of the Patents. Seller has not invited any third party to enter
into a license under any of the Patents or the Abandoned Assets. Seller has not
initiated any enforcement action with respect to any of the Patents or the
Abandoned Assets.


                                     Page 7

     6.9 PATENT OFFICE PROCEEDINGS. To Seller's knowledge, (a) none of the
Patents or the Abandoned Assets have been or are currently involved in any
reexamination, reissue, interference proceeding, or any similar proceeding, and
(b) no such proceedings are pending or threatened.

     6.10 FEES. All maintenance fees, annuities, and the like due or payable on
the Patents have been timely paid. For the avoidance of doubt, such timely
payment includes payment of any maintenance fees for which the fee is payable
(e.g., the fee payment window opens) even if the surcharge date or final
deadline for payment of such fee would be in the future.

     6.11 ABANDONED ASSETS. According to each applicable patent office, each of
the Abandoned Assets has expired, lapsed, or been abandoned or deemed withdrawn.

     6.12 PATENT FAMILY COMPLETE. The Patents include all (a) patents or patent
applications (i) to which any of the Patents directly or indirectly claims
priority, (ii) for which any of the Patents directly or indirectly forms a basis
for priority, and/or (iii) that are co-owned applications that incorporate by
reference, or are incorporated by reference into, the Patents; (b) reissues,
reexaminations, extensions, continuations, continuations in part, continuing
prosecution applications, requests for continuing examinations, divisions, and
registrations of any item in any of the foregoing categories; (c) foreign
patents, patent applications and counterparts relating to any item in any of the
foregoing categories, including, without limitation, certificates of invention,
utility models, industrial design protection, design patent protection, and
other governmental grants or issuances; and (d) any items in any of the
foregoing categories (a) through (c) whether or not expressly listed as Patents
and whether or not claims in any of the foregoing have been rejected, withdrawn,
cancelled, or the like. Notwithstanding the foregoing provisions of this

included in the Patents.
