               has been duly executed by the Company and, when delivered in
               accordance with the terms hereof, will constitute the valid and
               binding obligation of the Company enforceable against the Company
               in accordance with its terms except (i) as limited by general
               equitable principles and applicable bankruptcy, insolvency,

               affecting enforcement of creditors' rights generally, (ii) as
               limited by laws relating to the availability of specific
               performance, injunctive relief or other equitable remedies and

               be limited by applicable law.

          b.   NO CONFLICTS. The execution, delivery and performance of this
               Amendment by the Company and the consummation by the Company of
               the transactions contemplated hereby do not and will not: (i)
               conflict with or violate any provision of the Company's or any
               Subsidiary's certificate or articles of incorporation, memorandum
               of association, bylaws or other organizational or charter
               documents, or (ii) conflict with, or constitute a default (or an
               event that with notice or lapse of time or both would become a
               default) under, result in the creation of any Lien upon any of
               the properties or assets of the Company or any Subsidiary, or
               give to others any rights of termination, amendment, acceleration
               or cancellation (with or without notice, lapse of time or both)
               of, any agreement, credit facility, debt or other instrument
               (evidencing a Company or Subsidiary debt or otherwise) or other
               understanding to which the Company or any Subsidiary is a party
               or by which any property or asset of the Company or any
               Subsidiary is bound or affected, or (iii) assuming the accuracy
               of the representations made in Section 6A, conflict with or
               result in a violation of any law, rule, regulation, order,
               judgment, injunction, decree or other restriction of any court or
               governmental authority to which the Company or a Subsidiary is
               subject (including federal and state and Israeli securities laws
               and regulations), or by which any property or asset of the
               Company or a Subsidiary is bound or affected; except in the case
               of each of clauses (ii) and (iii), such as could not have or
               reasonably be expected to result in a Material Adverse Effect.

          all of the terms and conditions of the Loan Agreement, Note and
          Warrants shall continue in full force and effect after the execution
          of this Amendment and shall not be in any way changed, modified or
          superseded by the terms set forth herein, including, but not limited
          to, any other obligations the Company may have to the Holder under the
          Loan Agreement, Note and Warrants. Notwithstanding the foregoing, this

          and provisions of any other of the Loan Agreement, Note or Warrants,

          transmission or by e-mail delivery of a ".pdf" format data file, such
          signature shall create a valid and binding obligation of the party
          executing (or on whose behalf such signature is executed) with the
          same force and effect as if such facsimile or ".pdf" signature page
          were an original thereof.
