of entering into, any put option, short position, or other similar position with
respect to the Debenture or the Shares.

Common Stock which may be deemed beneficially owned through the ownership of the
unconverted portion of the Debenture), and (2) the number of shares of Common
Stock issuable upon the conversion of the Debenture with respect to which the
determination of this proviso is being made, would result in beneficial
ownership by the Buyer and its affiliates of more than 4.9% of the outstanding
shares of Common Stock. For purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13D-G
thereunder, except as otherwise provided in clause (1) of such proviso.

articles of incorporation or by-laws of the Company, (ii) any indenture,
mortgage, deed of trust, or other material agreement or instrument to which the

including any listing agreement for the Common Stock except as herein set forth,
(iii) any existing applicable law, rule, or regulation or any applicable decree,
judgment, or (iv) order of any court, United States federal or state regulatory

Debentures, the Company shall file all reports required to be filed with the SEC
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as
amended (the "1934 Act"), and the Company shall not terminate its status as an

not require the filing of a Registration Statement in respect of such stock
prior to the effective date of the Registration Statement under the Registration

reasonably required to cure any alleged default under agreements to which the
Company is or may become a party.

         H. AVAILABLE SHARES. The Company shall have at all times authorized and
reserved for issuance, free from preemptive rights, shares of Common Stock

time to time upon conversion of the Debenture in such amounts as specified from
time to time by the Company to the transfer agent, bearing the restrictive
legend specified in Section 4(b) of this Agreement prior to registration of the
Shares under the 1933 Act, registered in the name of the Buyer or its nominee
and in such denominations to be specified by the Buyer in connection with each
conversion of the Debenture. The Company warrants that no instruction other than
such instructions referred to in this Section 5 and stop transfer instructions

                                       8
<PAGE>   9

the Shares under the 1933 Act will be given by the Company to the transfer agent
and that the Shares shall otherwise be freely transferable on the books and
records of the Company as and to the extent provided in this Agreement, the
Registration Rights Agreement, and applicable law. Nothing in this Section shall
affect in any way the Buyer's obligations and agreement to comply with all
applicable securities laws upon resale of the Securities. If the Buyer provides
the Company with an opinion of counsel reasonably satisfactory to the Company
that registration of a resale by the Buyer of any of the Securities in
accordance with clause (1)(B) of Section 4(a) of this Agreement is not required
under the 1933 Act, the Company shall (except as provided in clause (2) of
Section 4(a) of this Agreement) permit the transfer of the Securities and, in
the case of the Shares, promptly instruct the Company's transfer agent to issue
one or more certificates for Common Stock without legend in such name and in
such denominations as speof the Buyer's representations and warranties herein,
upon the conversion of any Debenture by a person who is a non-U.S. Person, and
following the expiration of any applicable Restricted Period, the Company,
shall, at its expense, take all necessary action (including the issuance of an
opinion of counsel) to assure that the Company's transfer agent shall issue
stock certificates without restrictive legend or stop orders in the name of
Buyer (or its nominee (being a non-U.S. Person) or such non-U.S. Persons as may
be designated by Buyer) and in such denominations to be specified at conversion
representing the number of shares of Common Stock issuable upon such conversion,
as applicable. Nothing in this Section 4, however, shall affect in any way
Buyer's or such nominee's obligations and agreement to comply with all
applicable securities laws upon resale of the Securities.

         c. The Company will permit the Buyer to exercise its right to convert
the Debenture by telecopying an executed and completed Notice of Conversion to
the Company and delivering within three business days thereafter, the original
Notice of Conversion and the Debenture representing the Shares to the Company by
express courier to the Transfer Agent. Each date on which a Notice of Conversion
is telecopied to and received by the Company in accordance with the provisions
hereof shall be deemed a Conversion Date. The Company will transmit the
certificates representing the Shares of Common Stock issuable upon conversion of
any Debenture (together with the Debenture representing the Shares not so
converted) to the Buyer via express courier, by electronic transfer or
otherwise, within three business days after receipt by the Company of the
original Notice of Conversion and the Debenture representing the Shares to be
converted (the "Delivery Date").

         d. The Company understands that a delay in the issuance of the Shares
of Common Stock beyond the Delivery Date could result in economic loss to the
Buyer. As compensation to the Buyer for such loss, the Company agrees to pay
late payments to the Buyer for late issuance of Shares upon Conversion in
accordance with the following schedule (where "No. Business Days Late" is
defined as the number of business days beyond five (5) business days from
Delivery Date:
