rescinded and annulled by Holder at any time prior to payment hereunder and the
Holder shall have all rights as a Debenture Holder until such time, if any, as
the full payment under this Section shall have been received by it. No such
rescission or annulment shall affect any subsequent Event of Default or impair
any right consequent thereon.

     Section 4.  Conversion.
     ----------  ----------

          (a)    (i)  Conversion at Option of Holder. (A) This Debenture shall
                      ------------------------------
be convertible into shares of Common Stock  at the option of the Holder, in
whole or in part at any time and from time to time, after the Original Issue
Date (subject to the limitations on conversion set forth in Section 4(a)(ii)
hereof).   The number of shares of Common Stock  issuable upon a conversion
hereunder equals the sum of (i) the quotient obtained by dividing (x) the
outstanding principal amount of this Debenture to be converted by (y) the
Conversion Price (as defined herein), and (ii) the amount equal to (I) the
product of (x) the outstanding principal amount of this Debenture to be
converted and (y) the product of (1) the quotient obtained by dividing .12 by
360 and (2) the number of days for which such principal amount was outstanding,
divided by (II) the Conversion Price on the Conversion Date, provided, that if
                                                             --------
the Holder shall have elected to receive the interest due on a Conversion Date
in cash, subsection (ii) shall not be used in the calculation of the number of
shares of Common Stock  issuable upon a conversion hereunder.

                 (B)  The Holder shall effect conversions by delivering to the
Company a completed notice in the form attached hereto as Exhibit A (a
                                                          ----------
"Conversion Notice") including a completed Conversion Schedule in the form of
 -----------------
Schedule 1 to the Conversion Notice (on each Conversion Date, the "Conversion
----------                                                         ----------

Schedule"). The Conversion Schedule shall set forth the remaining principal
--------
amount of this Debenture and all accrued and unpaid interest thereon subsequent
to the conversion at issue. The date on which a Conversion Notice is delivered
is the "Conversion Date." Unless the Holder is converting the entire principal
        ---------------
amount outstanding under this Debenture, the Holder is not be required to
physically surrender this Debenture to the Company in order to effect
conversions. Subject to Section 4(b), each Conversion Notice, once given, shall
be irrevocable. Conversions hereunder shall have the effect of lowering the
outstanding principal amount of this Debenture plus all accrued and unpaid
interest thereon in an amount equal to the applicable conversion, which shall be
evidenced by entries set forth in the Conversion Schedule. The Holder and the
Company shall maintain records showing the principal amount converted and the
date of such conversions. In the event of any dispute or
<PAGE>

discrepancy, the records of the Holder shall be controlling and determinative in
the absence of manifest error.

                 (ii)  Certain Conversion Restrictions.
                       --------------------------------

                       (A)  A Holder may not convert Debentures or receive
shares of Common Stock as payment of interest hereunder to the extent such
conversion or receipt of such interest payment would result in the Holder,
together with any affiliate thereof, beneficially owning (as determined in
accordance with Section 13(d) of the Exchange Act and the rules promulgated
thereunder) in excess of 4.999% of the then issued and outstanding shares of
Common Stock, including shares issuable upon conversion of, and payment of
interest on, the Debentures held by such Holder after application of this
Section. Since the Holder will not be obligated to report to the Company the
number of shares of Common Stock it may hold at the time of a conversion
hereunder, unless the conversion at issue would result in the issuance of shares
of Common Stock in excess of 4.999% of the then outstanding shares of Common
Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in this Section will
limit any particular conversion hereunder and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which portion of the principal amount of Debentures are
convertible shall be the responsibility and obligation of the Holder. If the
Holder has delivered a Conversion Notice for a principal amount of Debentures
that, without regard to any other shares that the Holder or its affiliates may
beneficially own, would result in the issuance in excess of the permitted amount
hereunder, the Company shall notify the Holder of this fact and shall honor the
conversion for the maximum principal amount permitted to be converted on such
Conversion Date in accordance with the periods described in Section 4(b) and, at
the option of the Holder, either retain any principal amount tendered for
conversion in excess of the permitted amount hereunder for future conversions or
return such excess principal amount to the Holder. The provisions of this
Section may be waived by a Holder (but only as to itself and not to any other
Holder) upon not less than 61 days prior notice to the Company. Other Holders
shall be unaffected by any such waiver.

                       (B)  A Holder may not convert Debentures or receive
shares of Common Stock as payment of interest hereunder to the extent such
conversion or receipt of such interest payment would result in the Holder,
together with any affiliate thereof, beneficially owning (as determined in
accordance with Section 13(d) of the Exchange Act and the rules promulgated
thereunder) in excess of 9.999% of the then issued and outstanding shares of
Common Stock, including shares issuable upon conversion of, and payment of
interest on, the Debentures held by such Holder after application of this
Section. Since the Holder will not be obligated to report to the Company the
number of shares of Common Stock it may hold at the time of a conversion
hereunder, unless the conversion at issue would result in the issuance of shares
of Common Stock in excess of 9.999% of the then outstanding shares of Common
Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in this Section will
limit any particular conversion hereunder and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which portion of the principal amount of Debentures are
convertible shall be the responsibility
<PAGE>

and obligation of the Holder. If the Holder has delivered a Conversion Notice
for a principal amount of Debentures that, without regard to any other shares
that the Holder or its affiliates may beneficially own, would result in the
issuance in excess of the permitted amount hereunder, the Company shall notify
the Holder of this fact and shall honor the conversion for the maximum principal
amount permitted to be converted on such Conversion Date in accordance with the
periods described in Section 4(b) and, at the option of the Holder, either
retain any principal amount tendered for conversion in excess of the permitted
amount hereunder for future conversions or return such excess principal amount
to the Holder. The provisions of this Section may be waived by a Holder (but
only as to itself and not to any other Holder) upon not less than 61 days prior
notice to the Company. Other Holders shall be unaffected by any such waiver.

          (b)  (i)  Not later than three Trading Days after any Conversion Date,
the Company will deliver to the Holder (i) a certificate or certificates which
shall be free of restrictive legends and trading restrictions (other than those
required by Section 3.1(b) of the Purchase Agreement) representing the number of
shares of Common Stock issuable upon such conversion in accordance with the
terms hereof (subject to the limitations set forth in Section 4(a)(ii) hereof),
(ii)   if the Holder has elected to receive accrued interest in cash, the
Company will deliver to the Holder a bank check, payable to Holder, in the
amount of accrued and unpaid interest.  If requested by a Holder, the Company
will use its best efforts to deliver conversion shares electronically through
the Depository Trust Corporation or another established clearing corporation
performing similar functions.  If shares of Common Stock issuable following a
Conversion Notice are not delivered to or as directed by the Holder by the third
Trading Day after a Conversion Date, the Holder shall be entitled by written
notice to the Company at any time on or before its receipt of such shares, to
rescind such conversion, in which event the Company shall immediately return to
the Holder a Debenture in principal amount equal to the principal amount,
interest and all other amounts due in respect of the Conversion Notice (provided
the Holder is converting the entire principal amount outstanding under this
Debenture).

                    (ii)  If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 4(b)(i) by the third Trading Day
after the Conversion Date, the Company shall pay to such Holder, in cash, as
liquidated damages and not as a penalty, $2,500 for each Trading Day after such
third Trading Day until such certificates are delivered. Nothing herein shall
limit a Holder's right to pursue actual damages or declare an Event of Default
pursuant to Section 3 herein for the Company's failure to deliver certificates
representing shares of Common Stock upon conversion within the period specified
herein and such Holder shall have the right to pursue all remedies available to
it at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief. The exercise of any such rights shall not
prohibit the Holders from seeking to enforce damages pursuant to any other
Section hereof or under applicable law. Further, if the Company shall not have
delivered any cash due in respect of conversions of Debentures or as payment of
interest thereon by the third Trading Day after the Conversion Date, the Holder
may, by notice to the Company, require the Company to issue shares of Common
Stock pursuant to Section 4(c), except that for such purpose the Conversion
Price applicable thereto shall be the lesser of the
<PAGE>

Conversion Price on the Conversion Date and the Conversion Price on the date of
such Holder demand. Any such shares will be subject to the provision of this
Section.

                    (iii) In addition to any other rights available to the
Holder, if the Company fails for any reason to deliver to the Holder such
certificate or certificates pursuant to Section 4(b)(i) by the third Trading Day
after the Conversion Date, and if after such third Trading Day the Holder
purchases (in an open market transaction or otherwise) Common Stock to deliver
in satisfaction of a sale by such Holder of the Underlying Shares which the
Holder anticipated receiving upon such conversion (a "Buy-In"), then the Company
                                                      ------
shall (A) pay in cash to the Holder (in addition to any remedies available to or
elected by the Holder) the amount by which (x) the Holder's total purchase price
(including brokerage commissions, if any) for the Common Stock so purchased
exceeds (y) the product of (1) the aggregate number of shares of Common Stock
that such Holder anticipated receiving from the conversion at issue multiplied
by (2) the market price of the Common Stock at the time of the sale giving rise
to such purchase obligation and (B) at the option of the Holder, either reissue
Debentures in principal amount equal to the principal amount of the attempted
conversion or deliver to the Holder the number of shares of Common Stock that
would have been issued had the Company timely complied with its delivery
requirements under Section 4(b)(i).  For example, if the Holder purchases Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to
an attempted conversion of Debentures with respect to which the market price of
the Underlying Shares on the date of conversion was a total of $10,000 under
clause (A) of the immediately preceding sentence, the Company shall be required
to pay the Holder $1,000.  The Holder shall provide the Company written notice
indicating the amounts payable to the Holder in respect of the Buy-In.
Notwithstanding anything contained herein to the contrary, if a Holder requires
the Company to make payment in respect of a Buy-In for the failure to timely
deliver certificates hereunder and the Company timely pays in full such payment,
the Company shall not be required to pay such Holder liquidated damages under
Section 4(b)(ii) in respect of the certificates resulting in such Buy-In.

          (c)  (i)  The conversion price (the "Conversion Price") in effect on
                                               ----------------
any Conversion Date shall be the lesser of (1) $0.083 (the "Initial Conversion
                                                            ------------------
Price"), and (2) 67.67% of the average of the lowest three inter-day sales
-----
prices of the Common Stock (which need not occur on consecutive Trading Days but
which may not include prices that are sales by the Holder) during the twenty
Trading Days immediately preceding the applicable Conversion Date (which may
include Trading Days prior to the Original Issue Date), provided, that such
                                                        --------
twenty Trading Day period shall be extended for the number of Trading Days
during such period in which (A) trading in the Common Stock is suspended by the
OTC or a Subsequent Market on which the Common Stock is then listed, or (B)
after the date declared effective by the Commission, the Underlying Shares
Registration Statement is either not effective, the Prospectus included in the
Underlying Shares Registration Statement may not be used by the Holder for the
resale of Underlying Shares.

                    (ii)  If the Company, at any time while the Debentures are
outstanding, (a) shall pay a stock dividend or otherwise make a distribution or
distributions on shares of its Common Stock or any other equity or equity
equivalent securities payable in shares
<PAGE>

of Common Stock, (b) subdivide outstanding shares of Common Stock into a larger
number of shares, (c) combine (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (d) issue
by reclassification of shares of the Common Stock any shares of capital stock of
the Company, then the Initial Conversion Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding before such event and of which the
denominator shall be the number of shares of Common Stock outstanding after such
event. Any adjustment made pursuant to this Section shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such dividend or distribution and shall become effective immediately
after the effective date in the case of a subdivision, combination or re-
classification.

                    (iii)  If the Company, at any time while the Debentures are
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to Holders) entitling them to subscribe for or purchase shares of
Common Stock at a price per share less than the Per Share Market Value at the
record date mentioned below, then the Conversion Price shall be multiplied by a
fraction, of which the denominator shall be the number of shares of the Common
Stock (excluding treasury shares, if any) outstanding on the date of issuance of
such rights or warrants plus the number of additional shares of Common Stock
offered for subscription or purchase, and of which the numerator shall be the
number of shares of the Common Stock (excluding treasury shares, if any)
outstanding on the date of issuance of such rights or warrants plus the number
of shares which the aggregate offering price of the total number of shares so
offered would purchase at such Per Share Market Value.  Such adjustment shall be
made whenever such rights or warrants are issued, and shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such rights, options or warrants.  However, upon the expiration of
any such right, option or warrant to purchase shares of the Common Stock the
issuance of which resulted in an adjustment in the Conversion Price pursuant to
this Section, if any such right, option or warrant shall expire and shall not
have been exercised, the Conversion Price shall immediately upon such expiration
be recomputed and effective immediately upon such expiration be increased to the
price which it would have been (but reflecting any other adjustments in the
Conversion Price made pursuant to the provisions of this Section after the
issuance of such rights or warrants) had the adjustment of the Conversion Price
made upon the issuance of such rights, options or warrants been made on the
basis of offering for subscription or purchase only that number of shares of the
Common Stock actually purchased upon the exercise of such rights, options or
warrants actually exercised.

                    (iv)   If the Company or any subsidiary thereof, as
applicable with respect to Common Stock Equivalents (as defined below), at any
time while Debentures are outstanding shall issue shares of Common Stock or
rights, warrants, options or other securities or debt that are convertible into
or exchangeable for shares of Common Stock ("Common Stock Equivalents"),
                                             ------------------------
entitling any Person to acquire shares of Common Stock at a price per share less
than the Conversion Price (if the holder of the Common Stock or Common Stock
Equivalent so issued shall at any time, whether by operation of purchase price
adjustments, reset provisions, floating conversion, exercise or exchange prices
or otherwise, or due to warranty options or rights per share which are issued in
connection with such issuance, be entitled to receive shares
<PAGE>

of Common Stock at a price per share which is less than the Conversion Price,
such issuance shall be deemed to have occurred for less than the Conversion
Price), then, at the sole option of the Holder, the Conversion Price shall be
adjusted to mirror the conversion, exchange or purchase price for such Common
Stock or Common Stock Equivalents (including any reset provisions thereof) at
issue. Such adjustment shall be made whenever such Common Stock or Common Stock
Equivalents are issued. The Company shall notify the Holder and the Escrow Agent
in writing, no later than the business day following the issuance of any Common
Stock or Common Stock Equivalent subject to this section, indicating therein the
applicable issuance price, or of applicable reset price, exchange price,
conversion price and other pricing terms. No adjustment under this Section shall
be made as a result of (i) issuances of Common Stock or Common Stock Equivalents
to the extent disclosed in Schedule 2.1(c) to the Purchase Agreement, (ii)
issuances and exercises of options to purchase shares of Common Stock issued for
compensatory purposes pursuant to any of the Company's stock option or stock
purchase plans, or (iii) exercises under the Warrants (as defined in the
Purchase Agreement).

               (v)  If the Company, at any time while Debentures are
outstanding, shall distribute to all holders of Common Stock (and not to
Holders) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security, then in each such case the Conversion
Price at which Debentures shall thereafter be convertible shall be determined by
multiplying the Conversion Price in effect immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by
a fraction of which the denominator shall be the Per Share Market Value
determined as of the record date mentioned above, and of which the numerator
shall be such Per Share Market Value on such record date less the then fair
market value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holders of the
portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

               (vi) In case of any reclassification of the Common Stock or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, the Holders shall have the right thereafter
to, at their option, (A) convert the then outstanding principal amount, together
with all accrued but unpaid interest and any other amounts then owing hereunder
in respect of this Debenture only into the shares of stock and other securities,
cash and property receivable upon or deemed to be held by holders of the Common
Stock following such reclassification or share exchange, and the Holders of the
Debentures shall be entitled upon such event to receive such amount of
securities, cash or property as the shares of the Common Stock of the Company
into which the then outstanding principal amount, together with all accrued but
unpaid interest and any other amounts then owing hereunder in respect of this
Debenture could have been converted immediately prior to such reclassification
or share exchange would have been entitled or (B) require the Company to prepay
the aggregate of its outstanding principal amount of Debentures, plus all
interest and other amounts due and payable thereon, at a price determined in
accordance with Section 3(b).
<PAGE>

The entire prepayment price shall be paid in cash. This provision shall
similarly apply to successive reclassifications or share exchanges.

                    (vii)   All calculations under this Section 4 shall be made
to the nearest cent or the nearest 1/100th of a share, as the case may be. No
adjustments in either the Conversion Price or the Initial Conversion Price shall
be required if such adjustment is less than $0.01, provided, however, that any
                                                   --------
adjustments which by reason of this Section are not required to be made shall be
carried forward and taken into account in any subsequent adjustment.

                    (viii)  Whenever either the Initial Conversion Price or the
Conversion Price is adjusted pursuant to any of Section 4(c)(ii) - (v), the
Company shall promptly mail to each Holder a notice setting forth the Initial
Conversion Price or Conversion Price (as applicable) after such adjustment and
setting forth a brief statement of the facts requiring such adjustment.

                    (ix)    If (A) the Company shall declare a dividend (or any
other distribution) on the Common Stock; (B) the Company shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock; (C) the
Company shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any shares of capital stock of any
class or of any rights; (D) the approval of any stockholders of the Company
shall be required in connection with any reclassification of the Common Stock,
any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; (E) the Company shall authorize the voluntary or
involuntary dissolution, liquidation or winding up of the affairs of the
Company; then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of the Debentures, and shall
cause to be mailed to the Holders at their last addresses as they shall appear
upon the stock books of the Company, at least 20 calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided, that the
                                                         --------
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice.  Holders are entitled to convert Debentures during the 20-day
period commencing the date of such notice to the effective date of the event
triggering such notice.

                    (x)    In case of any (1) merger or consolidation of the
Company with or into another Person, or (2) sale by the Company of more than
one-half of the assets of the Company in one or a series of related
transactions, a Holder shall have the right to (A) exercise
<PAGE>

any rights under Section 3(b), (B) convert its aggregate principal amount of
Debentures then outstanding into the shares of stock and other securities, cash
and property receivable upon or deemed to be held by holders of Common Stock
following such merger, consolidation or sale, and such Holder shall be entitled
upon such event or series of related events to receive such amount of
securities, cash and property as the shares of Common Stock into which such
aggregate principal amount of Debentures could have been converted immediately
prior to such merger, consolidation or sales would have been entitled, or (C) in
the case of a merger or consolidation, require the surviving entity to issue to
the Holder convertible debentures with a principal amount equal to the aggregate
principal amount of Debentures then held by such Holder, plus all accrued and
unpaid interest and other amounts owing thereon, which newly issued convertible
debentures shall have terms identical (including with respect to conversion) to
the terms of this Debenture, and shall be entitled to all of the rights and
privileges of a Holder of Debentures set forth herein and the agreements
pursuant to which the Debentures were issued. In the case of clause (C), the
conversion price applicable for the newly issued shares of convertible preferred
stock or convertible debentures shall be based upon the amount of securities,
cash and property that each share of Common Stock would receive in such
transaction and the Conversion Price in effect immediately prior to the
effectiveness or closing date for such transaction. The terms of any such
merger, sale or consolidation shall include such terms so as to continue to give
the Holders the right to receive the securities, cash and property set forth in
this Section upon any conversion or redemption following such event. This
provision shall similarly apply to successive such events.

          (d)  The Company covenants that it will at all times reserve and keep
available out of its authorized and unissued shares of Common Stock solely for
the purpose of issuance upon conversion of the Debentures and payment of
interest on the Debentures, each as herein provided, free from preemptive rights
or any other actual contingent purchase rights of persons other than the
Holders, not less than such number of shares of the Common Stock as shall
(subject to any additional requirements of the Company as to reservation of such
shares set forth in the Purchase Agreement) be issuable (taking into account the
adjustments and restrictions of Section 4(b)) upon the conversion of the
outstanding principal amount of the Debentures and payment of interest
hereunder.  The Company covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized, issued and fully
paid, nonassessable and, if the Underlying Shares Registration Statement has
been declared effective under the Securities Act, registered for public sale in
accordance with such Underlying Shares Registration Statement.

          (e)  Upon a conversion hereunder the Company shall not be required to
issue stock certificates representing fractions of shares of the Common Stock,
but may if otherwise permitted, make a cash payment in respect of any final
fraction of a share based on the Per Share Market Value at such time.  If the
Company elects not, or is unable, to make such a cash payment, the Holder shall
be entitled to receive, in lieu of the final fraction of a share, one whole
share of Common Stock.

          (f)  The issuance of certificates for shares of the Common Stock on
conversion of the Debentures shall be made without charge to the Holders thereof
for any
<PAGE>

documentary stamp or similar taxes that may be payable in respect of the issue
or delivery of such certificate, provided that the Company shall not be required
to pay any tax that may be payable in respect of any transfer involved in the
issuance and delivery of any such certificate upon conversion in a name other
than that of the Holder of such Debentures so converted and the Company shall
not be required to issue or deliver such certificates unless or until the person
or persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

          (g)    Any and all notices or other communications or deliveries to be
provided by the Holders hereunder, including, without limitation, any Conversion
Notice, shall be in writing and delivered personally, by facsimile, sent by a
nationally recognized overnight courier service or sent by certified or
registered mail, postage prepaid, addressed to the Company, at 3704 32/nd/

     Section 5.  Optional Prepayment.
     ----------  -------------------

          (a)    Subject to Section 5(b) below, the Company shall have the
right, exercisable at any time and from time to time after the Original Issue
Date, in accordance with the terms hereof and upon ten Trading Days' prior
written notice to the Holders to be prepaid (an "Optional Prepayment Notice"),
                                                 --------------------------
to prepay all or any portion of the outstanding principal amount of the
Debentures which has not previously been repaid or for which Conversion Notices
have not previously been delivered. The prepayment price applicable to
prepayments under this Section 5(a) shall equal the Prepayment Price and shall
be paid in cash. Any such prepayment shall be free of any claim of
subordination. The Holders shall have the right to tender, and the Company shall
honor, Conversion Notices delivered prior to the expiration of the tenth Trading
Day after receipt by the Holders of an Optional Prepayment Notice for such
Debentures (the
<PAGE>

tenth Trading Day after receipt by the Holders of an Optional Prepayment Notice
is referred to herein as the "Optional Prepayment Date")
                              ------------------------

          (b)  The Company shall not be entitled to deliver an Optional
Prepayment Notice to the Holder (and, if after delivery thereof and prior to the
Optional Prepayment Date, any of the following conditions shall cease to be met,
such notice, at the option of the Holders, shall be deemed no longer effective)
if:  (i) the number of shares of Common Stock at the time authorized, unissued
and unreserved for all purposes is insufficient to satisfy the Company's
conversion obligations of the aggregate principal amount of Debentures then
outstanding, or (ii) there is neither an effective Underlying Shares
Registration Statement under which the Holders can resell all of the issued
Underlying Shares and all of the Underlying Shares as are issuable upon
conversion in full of the principal amount of Debentures subject to an Optional
Prepayment Notice nor may all of such issued and issuable Underlying Shares be
sold by the Holders subject to such prepayment without volume restrictions
pursuant to Rule 144 promulgated under the Securities Act, as determined by
counsel to the Company pursuant to a written opinion letter, addressed to the
Company's transfer agent in the form and substance acceptable to the Holders and
such transfer agent, or (iii) the Common Stock is not then listed or quoted for
trading on the OTC or on a Subsequent Market.

          (c)  If any portion of the Prepayment Price shall not be paid by the
Company by the second (2/nd/) Trading Day following the Optional Prepayment
Date, the Prepayment Price shall be increased by 15% per annum (or such lesser
maximum amount that is permitted to be paid by applicable law) to accrue daily
from the date such interest is due hereunder through and including the date of
payment (which amount shall be paid as liquidated damages and not as a penalty).
In addition, if any portion of the Prepayment Price remains unpaid through the
expiration of the Optional Prepayment Date, the Holder subject to such
prepayment may elect by written notice to the Company to either (x) demand
conversion in accordance with the formula and the time period therefor set forth
in Section 4 of any portion of the principal amount of Debentures for which the
Prepayment Price, plus accrued liquidated damages and accrued interest thereon,
has not been paid in full (the "Unpaid Prepayment Principal Amount"), in which
                                ----------------------------------
event the applicable Per Share Market Value shall be the lower of the Per Share
Market Value calculated on the Optional Prepayment Date and the Per Share Market
Value as of the Holder's written demand for conversion, or (y) invalidate ab
initio such optional prepayment, notwithstanding anything herein contained to
the contrary.  If the Holder elects option (x) above, the Company shall, within
five Trading Days after such election is deemed delivered hereunder, deliver to
the Holder the shares of Common Stock issuable upon conversion of the Unpaid
Prepayment Principal Amount subject to such conversion demand and otherwise
perform its obligations hereunder with respect thereto.  If the Holder elects
option (y) above, the Company shall promptly, and in any event not later than
five Trading Days from receipt of notice of such election, return to the Holder
new Debentures for the full Unpaid Prepayment Principal Amount and shall no
longer have any prepayment rights under this Debenture.  If, upon an election
under option (x) above, the Company fails to deliver certificates representing
the shares of Common Stock issuable upon conversion of the Unpaid Prepayment
Principal Amount within the time period set forth in this Section, the Company
shall pay to the Holder in cash, as liquidated
<PAGE>

damages and not as a penalty, $2,500 per day until the Company delivers such
certificates to the Holder.
