5.   REGISTRATION RIGHTS

     (a) Definitions. For purposes of this Paragraph 5, the following terms
shall have the respective meanings set forth below:

          (i) "Commission" shall mean the Securities and Exchange Commission or
          any other Federal agency at the time administering the Act.

          (ii) The term "holder or holders of Registrable Stock" shall mean the

          or similar document in compliance with the Act, and the declaration or
          ordering of effectiveness of such registration statement or document
          by the Commission.

          (iv) The term "Registrable Stock" means (a) the shares issued pursuant
          to this Note; provided, however, that shares of Registrable Stock will
          cease to be Registrable Stock if they are sold or transferred pursuant
          to a registered public offering or other transaction which does not
          result in restrictions on resale being imposed on the public transfer
          by virtue of federal or state securities laws; and provided further
          that Registrable Stock will cease to be Registrable Stock if the

                                       4

     (b) Demand Registration.

          (i) Upon the written request of any holder or holders ("Initiating
          Holders") of at least 30% of the shares of Registrable Stock, which
          request shall state the intended method of disposition by such
          Initiating Holders and shall request that the Maker effect the
          registration of all or part of the Registrable Stock under the
          Securities Act, the Maker shall promptly give written notice of such
          requested registration to all other holders, if any, of Registrable
          Stock. If, after the expiration of 30 days from the giving of such
          notice to the holders of Registrable Stock, the Maker shall have
          received written requests to register at least 50% of the shares of
          Registrable Stock, which requests shall state the intended method of
          disposition of such securities by such holders, the Maker shall use
          all reasonable efforts to prepare and file with the Commission a
          registration statement and such other documents, including a
          prospectus, as may be necessary to permit a public offering and sale
          of such Registrable Stock in the United States in compliance with the
          provisions of the Securities Act, all to the extent required to permit
          the disposition (in accordance with the intended methods thereof as
          aforesaid) by the holders of the Registrable Stock so to be registered
          (the "Participating Holders"). If such sale of Registrable Stock is to
          be pursuant to an underwritten offering, the underwriter shall be
          selected by the Initiating Holders and shall be reasonably acceptable
          to the Maker. If the underwriter selected determines that the number
          of shares so to be included is required to be limited due to market
          conditions or otherwise, the holders of Registrable Stock proposing to
          sell their shares in such underwritten registration shall share pro
          rata (according to the number of shares requested to be registered) in
          the number of shares being underwritten (as determined by such
          underwriter) and registered for their account. The Maker shall only be
          required to effect two registrations pursuant to this Paragraph 5(b).

          (ii) The Maker shall not be required to effect any registration under
          this Paragraph 5(b) within nine months after the completion of any
          Registered offering of its securities pursuant.

          (iii) The Maker shall have the right to include in any registration
          statement or post-effective amendment filed pursuant to this Paragraph
          5(b), other securities of the Maker then proposed to be distributed,
          except that, to the extent consistent with the rights of other holders
          of the Maker's securities, if and to the extent that the underwriter
          or underwriters acting with respect of such registered offering
          reasonably determine that the inclusion of such other securities may
          substantially prejudice or hinder the offering of Registrable Stock,
          the number of such other securities shall be reduced or eliminated
          prior to any reduction in the number of shares of Registrable Stock so
          to be registered.

                                       5
<PAGE>


          (iv) If the registration under this Paragraph 5(b) is effected on a
          Form S-3 (or any successor form thereto), and the effectiveness of
          such registration statement can be maintained without significant
          additional expense to the Maker, then the Maker agrees to maintain the
          effectiveness of such registration statement for a period of six
          months after its initial effective date.

     (c) Incidental or Piggyback Registration.

          (i) If the Maker at any time or from time to time proposes to file
          with the Commission a registration statement under the Act with
          respect to any proposed distribution of any of its securities (other
          than a registration to be effected on Form S-4, S-8 or other similar
          limited purpose form), whether for sale for its own account or for the
          account of any other person holding registration rights with respect
          to the securities of the Maker, then the Maker shall give written
          notice of such proposed filing to the holders of Registrable Stock at
          least ten days before the anticipated filing date, and such notice
          shall describe in detail the proposed registration and distribution
          (including those jurisdictions where registration or qualification
          under the securities or blue sky laws is intended) and shall offer the
          holders of Registrable Stock the opportunity to register such number
          of shares of Registrable Stock as the holders of Registrable Stock may
          request. Upon receipt by the Maker by the anticipated filing date of
          written requests from Participating Holders for the Maker to register
          their Registrable Stock, the Maker shall permit, or in the event of an
          underwritten offering, shall use its reasonable best efforts to cause
          the managing underwriter or underwriters of such proposed underwritten
          offering to permit, the Participating Holders to include such
          Registrable Stock in such offering on the same terms and conditions as
          any similar securities of the Maker included therein; provided,
          however, that if in the opinion of the managing underwriter or
          underwriters of such offering, the inclusion of the total amount
          Registrable Stock which it or the Maker, and any other persons or
          entities, intend to include in such offering would interfere, hinder,
          delay, reduce or prevent the effectiveness or sale of the Maker's
          securities proposed to be so registered, or would otherwise adversely
          affect the success of such offering, then the amount or kind of
          securities to be offered for the accounts of the Maker and each holder
          of Maker Securities (including without limitation Registrable Stock)
          or securities convertible into or exercisable for Maker securities
          proposed to be registered (other than any persons exercising demand
          registration rights) shall be reduced (or eliminated) in proportion to
          their respective values to the extent necessary to reduce the total
          amount of securities to be included in such offering on behalf of such
          holders of securities to the amount recommended by such managing
          underwriter. For purposes of this Paragraph, "value" shall mean
          principal amount with respect to debt securities and the proposed
          offering price per share with respect to equity securities.
          Notwithstanding the foregoing, if, at any time after giving written
          notice of its intention to register securities and prior to the
          effectiveness of the registration statement filed in connection with
          such registration, the Maker determines for any reason either not to
          effect such registration or to delay such registration, the Maker may,
          at its election, by delivery of written notice to the Participating
          Holders, (i) in the case of a determination not to effect
          registration, relieve itself of its obligations to register any
          Registrable Stock in connection with such registration, or (ii) in the
          case of determination to delay the registration, delay the
          registration of such Registrable Stock for the same period as the
          delay in the registration of such other shares of Common Stock or
          other securities convertible into or exercisable for Common Stock.

                                       6
<PAGE>


          (ii) The Maker shall not be required to include any of the Registrable
          Stock of a Participating Holder in any registration statement or
          post-effective amendment prepared at its own instance unless such
          Participating Holder shall furnish such information and sign such
          documents as may be required by the Commission or reasonably requested
          by the Maker, in accordance with generally accepted practices, in
          connection with such proposed distribution.

     (d) Covenants of the Maker with Respect to Registration. In connection with
any registration under this Paragraph 5, the Maker will, as expeditiously as is
reasonably practicable:

          respect to such Participating Holders and, subject to the last

          to cause such registration statement to become effective.

          (ii) Prepare and file with the Commission such amendments and
          supplements to such registration statement and prospectus used in
          connection with such registration statement as may be necessary to
          comply with the provisions of the Act with respect to the disposition
          of all securities covered by such registration statement.

          (iii) Furnish to the Participating Holders such numbers of copies of a
          prospectus, including, if applicable, a preliminary prospectus, in
          conformity with the requirements of the Act, and such other documents
          as the selling shareholders may reasonably request in order to
          facilitate the disposition of Registrable Stock owned by the
          Participating Holders.

          (iv) Use its best efforts to register and qualify the securities
          covered by such registration statement under such other securities or
          blue sky laws of such jurisdictions within the United States as shall
          be reasonably requested by the Participating Holders; provided,
          however, that the Maker shall not be required in connection therewith
          or as a condition thereto to qualify to do business or to file a
          general consent to service of process in any such states or
          jurisdictions.

          (v) In the event of any underwritten public offering, enter into and
          perform its obligations under an underwriting agreement, in usual and
          customary form, with the managing underwriter of such offering. The
          Participating Holders shall also enter into and perform their
          obligations under such an agreement.

          relating to Registrable Stock covered by such registration statement
          is required to be delivered under the Act, of the happening of any
          event as a result of which the prospectus included in such
          registration statement, as then in effect, includes an untrue
          statement of a material fact or omits to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading in the light of the circumstances then
          existing.

registration statements filed under this Paragraph 5 including, without
