      period the Maker may make such payment(s) as are due and payable and prevent
      a
      default of this Note, an “Event of Default” will have occurred. Upon an Event of
      Default and until such Event of Default shall have been cured, the holder of
      this Note may, at its option, without further notice or demand, (i) declare

      Note shall be applied first to payment of accrued interest as of the date of
      such prepayment and the balance, if any, shall be applied in reduction of the
      unpaid principal.

                its
                common stock or the securities holdings of any of its controlling
                shareholders, on each such occasion it shall, without cost or expense,

                in this
                transaction, in such registration or qualification. The Company shall
                keep
                the registration effective until such time as the Purchaser has sold
                its
                Shares or the Shares are eligible to be transferred without restriction
                pursuant to the provisions of Rule 144(k) which was promulgated by
                the
                Securities and Exchange Commission pursuant to §4(1) of the Securities Act
                of 1933, as amended. The Purchaser agrees to provide an opinion of
                counsel
                with respect to any sales of the Shares by the Purchaser if such
                sale is
                permissible under Rule 144(k).

                expenses in connection with preparing and filing any registration
                statement under Paragraph “A” of this Article “6” of this Agreement shall
                be borne in full by the Company; provided, however, that the Purchaser
                shall pay any and all underwriting commissions and expenses and the
                fees
                and expenses of any legal counsel selected by the Purchaser to represent
                it with respect to the sale of the
                Securities.





7.  No
      Usury Intended; Usury Savings Clause . I n
      no
      event shall interest contracted for, charged or received hereunder, plus any
      other charges in connection herewith which constitute interest, exceed the
      maximum interest permitted by applicable law. The amounts of such interest
      or
      other charges previously paid to the holder of the Note in excess of the amounts
      permitted by applicable law shall be applied by the holder of the Note to reduce
      the principal of the indebtedness evidenced by the Note, or, at the option
      of
      the holder of the Note, be refunded. To the extent permitted by applicable
      law,
      determination of the legal maximum amount of interest shall at all times be
      made
      by amortizing, prorating, allocating and spreading in equal parts during the
      period of the full stated term of the loan and indebtedness, all interest at
      any
      time contracted for, charged or received from the Maker hereof in connection
      with the loan and indebtedness evidenced hereby, so that the actual rate of
      interest on account of such indebtedness is uniform throughout the term
      hereof.




8.  Waivers .
      The
      Maker hereby waives presentment, protest, demand for payment, notice of dishonor
      and all other notices of any kind. No waiver of any default shall operate as
      a
      waiver of any other default or of the same default on any future occasion,
      and
      no action to enforce payment hereunder nor any indulgences or other arrangements
      granted to the Maker, including any extension of time for payment due thereon,
      shall release, waive or otherwise affect any right of the owner or holder
      hereof.
