                           regulatory body whose approval is required, as

                           Holder shall have the right, at its option, to
                           convert all or part of the principal and accrued
                           interest due under this debenture (the
                           "Indebtedness") into shares of common stock of the
                           Company at a price, which shall be the lower of,

                           Company's  common stock,  Holder shall (i) surrender
                           this  debenture  at the  principal  office of the
                           Company,  duly  endorsed in blank,  and (ii) give

                           Company that it elects to convert all, or any part
                           of this debenture, which notice shall specify the
                           portion hereof to be converted.  As promptly as
                           possible thereafter, the Company shall issue and
                           deliver to Holder certificates representing the
                           number of its common shares into which this
                           debenture has been converted.  Thereupon, accrued
                           interest and the principal amount of this
                           debenture, or the portion thereof converted, shall
                           be deemed to have been satisfied and discharged,
                           and the common shares into which this debenture
                           shall be so converted shall be fully paid and
                           non-assessable shares.  In the event this debenture
                           has not been converted in full, the Company shall
                           issue and deliver to Holder a new debenture
                           identical to the one surrendered, except that it
                           shall be in the correct principal amount after the
                           partial conversion.

                  (c)      The conversion rights created by this debenture are
                           non-assignable without the written consent of the
                           Company. All shares issued upon the exercise of the
                           conversion rights created by this debenture shall be
                           subject to that certain Registration Rights Agreement
                           between Holder and the Company a copy of which is
                           attached as Exhibit B hereto.

                  5.       Transfer and Investment Representation. By acceptance
                           --------------------------------------
of this debenture, Holder represents that this debenture is being acquired and
will be acquired for Holder's own account for investment and with no intention
at the time of such purchase or acquisition of distributing or reselling the
same or any part thereof to the public. Holder understands that this debenture
has not been registered under the federal Securities Act of 1933 or any state
securities laws and that this debenture may not be subsequently transferred or
resold without (i) such registration, or (ii) the existence of an exemption
from the applicable registration requirements as confirmed in writing by legal
counsel reasonably acceptable to the Company. In furtherance of this
representation, Holder agrees that this debenture shall be legended to prohibit
transfer, sale or other disposition except in compliance with such investment
representation.

                  6.       Transfer of Debenture. By acceptance of this
                           ---------------------
debenture, Holder agrees to give written notice to the Company before
transferring this debenture or transferring any shares of the Company's common
stock issuable or issued upon the exercise of this debenture of Holder's
intention to do so, describing briefly the manner of any proposed transfer of
this debenture or Holder's intention as to the shares of common stock issuable
upon the exercise hereof or the intended disposition to be made of shares of
common stock upon such exercise. Promptly upon receiving such written notice,
the Company shall present copies thereof to legal counsel for the Company. If,
in the opinion of such counsel, the proposed transfer of this debenture or
disposition of shares may be effected without registration or qualification
(under any federal or state law) of this debenture or the shares of common
stock issuable or issued upon the exercise hereof, the Company, as promptly as
practicable, shall notify Holder of such opinion, whereupon Holder shall be
entitled to transfer this debenture, or to exercise this debenture in
accordance with its terms and dispose of the shares received upon such exercise
or to dispose of shares of common stock received upon the previous exercise of
this debenture, all in accordance with the terms of the notice

                                                                              3

foregoing restrictions on transfer and disposition may be endorsed on this
debenture or the certificates for such shares.

                           respect to, or result in the creation or imposition
                           of any lien, charge, encumbrance or claim of any
                           nature whatsoever upon any of the property, real or
                           personal, tangible or intangible, of the Company
                           pursuant to, any agreement or instrument to which
                           the Company is a party or by which the Company is
                           bound, except for any lien, charge, encumbrance or
                           claim that individually or in the aggregate does

                           debenture by the Company will not result in any
                           violation by the Company of any law, rule or
                           regulation applicable to the Company. The Company
                           is not a party to, or subject to or bound by, any
                           judgment, injunction or decree of any court or
                           governmental authority which may restrict or
                           interfere with the performance of this debenture.

                           balance sheet and a statement of receipts and
                           expenditures) for such fiscal quarter, which
                           financial statements shall be certified as correct by
                           the chief financial officer of the Company.

                                                                               4

                           Company, for the purpose of inspecting the books
                           and records of the Company; provided, however, that
                           any information obtained by Holder as a result of
                           such inspection shall be maintained by Holder as
