      the validity and enforceability of the Fa-cility Agreement, whether the
      indebtedness, obligations and liabilities of the Borrower is from time to
      time reduced and thereafter increased or entirely extinguished and later
      reincurred, to pay freely transferable and effective to you, your

      that the Borrower has not fulfilled its obligations under the Facility
      Agreement - a maximum amount up to

                               (euro) 1.000.000,00

                     - hereinafter called ,,Principal Sum" -

2.    The Principal Sum will be increased by any expenses, charges and interest,
      especially but not limited to legal costs, to be paid on the Principal Sum
      covered by this Indemnity or arising pursuant to the enforcement thereof.
      This also applies if the aforementioned amounts are added to the Principal
      Sum by balance determination on the current account. Such amounts can be
      claimed in addition to the Principal Sum.

3.    Our obligation hereunder shall be absolute and unconditional, irrespective
      of, and shall not be affected or impaired by, any circumstance whatsoever,

      amounts as may be necessary to ensure that you receive a net amount equal
      to the full amount which you would have received had payment not been made
      subject to such tax.

      obtaining judgement in any court to convert the sum due hereunder into any
      other currency, we hereto agree, to the fullest extent permitted by law

      that the rate of exchange used shall be the rate at which in accordance
      with normal banking pro-cedures you could purchase such other currency on
      the business day preceding the day on which final judgement is given.

      month and 1 day after the date on which the Borrower's obligations
      under the Facility Agreement have been fulfilled you will immediately
      declare such release in writing. Should any provision contained in this
      indemnity be found invalid, such invalidity shall not affect the validity
      of the remaining provisions which shall continue to be in full force and
