Article 3 and (ii) cause to be mailed for delivery by overnight courier a
certificate or certificate(s) representing the number of Common Shares to which
the Holder is entitled by virtue of such conversion, and cash, as provided in
Section 3.3, in respect of any fraction of a Common Share deliverable upon such
conversion and cash or shares of Common Stock, as applicable, representing the
amount of accrued and unpaid interest on this Debenture as of the Conversion
Date. Such conversion shall be deemed to have been effected at the time at which
the Conversion Notice indicates, and at such time the rights of the Holder of
this Debenture, as such (except if and to the extent that any Principal Amount
thereof remains unconverted), shall cease and the Person and Persons in whose
name or names the Common Stock Issued at Conversion shall be issuable shall be
deemed to have become the holder or holders of record of the Common Shares
represented thereby, and all voting and other rights associated with the
beneficial ownership of such Common Shares shall at such time vest with such

and to the extent that any Principal Amount thereof remains unconverted). No
cash payment aggregating less than $1.00 shall be required to be given unless
specifically requested by the Holder.

         SECTION 3.3 Fractional Shares. No fractional Common Shares or scrip
representing fractional Common Shares shall be delivered upon conversion of this
Debenture. Instead of any fractional Common Shares which otherwise would be
delivered upon conversion of this Debenture, the Company shall pay a cash
adjustment in respect of such fraction in an amount equal to the same fraction
multiplied by the Current Market Price on the Conversion Date. No cash payment
of less than $1.00 shall be required to be given unless specifically requested
by the Holder.

         SECTION 3.4 Adjustments. The Conversion Price and the number of shares
deliverable upon conversion of this Debenture are subject to adjustment from
time to time as follows:

Reclassification, Etc. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another Person
(where the Company is not the survivor or where there is a change in or
distribution with respect to the Common Stock of the Company), sell, convey,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another Person, or effectuate a transaction or series of related
transactions in which more than fifty percent (50%) of the voting power of the
Company is disposed of (each, a "FUNDAMENTAL CORPORATE CHANGE") and, pursuant to
the terms of such Fundamental Corporate Change, shares of common stock of the
successor or acquiring corporation, or any cash, shares of stock or other
securities or property of any nature whatsoever (including warrants or other
subscription or purchase rights) in addition to or in lieu of common stock of
the successor or acquiring corporation ("OTHER PROPERTY") are to be received by
or distributed to the holders of Common Stock of the Company, then the Holder of
this Debenture shall have the right thereafter, at its sole option, to (a)
require the Company to prepay this Debenture for cash together with all accrued
and unpaid interest thereon to the date of prepayment, (b) receive the number of
shares of common stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and Other Property as is receivable
upon or as a result of such Fundamental Corporate Change by a holder of the
number of shares of Common Stock into which the outstanding portion of this
Debenture may be converted at the Conversion Price applicable immediately prior
to such Fundamental Corporate Change or (c) require the Company, or such
successor, resulting or purchasing corporation, as the case may be, to, without
benefit of any additional consideration therefor, execute and deliver to the
Holder a debenture with substantial identical rights, privileges, powers,
restrictions and other terms as this Debenture in an amount equal to the amount
outstanding under this Debenture immediately prior to such Fundamental Corporate
Change. For purposes hereof, "COMMON STOCK OF THE SUCCESSOR OR ACQUIRING
CORPORATION" shall include stock of such corporation of any class which is not
preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to prepayment and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event and any
warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions shall similarly apply to successive Fundamental Corporate
Changes.

action or proceeding arising out of or relating to this Debenture shall be
