presentment, demand, protest or other notice of any kind, and the Holder may
immediately and without expiration of any grace period enforce any and all of
its rights and remedies hereunder and all other remedies available to it under
applicable law. Such declaration may be rescinded and annulled by Holder at any
time prior to payment hereunder. No such rescission or annulment shall affect
any subsequent Event of Default or impair any right consequent thereon.

         SECTION 3.        CONVERSION.

         (a) CONVERSION AT OPTION OF HOLDER.

                  (i) This Note 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 (as defined in Section 5). The number of
shares of Common Stock issuable upon a conversion hereunder ("the Conversion
Shares") shall equal fifty percent (50%) of the outstanding amount of principal
and accrued interest on this Note at the Conversion Date. The Obligor shall use
its best efforts to deliver Common Stock certificates to the Holder prior to the
tenth (10th) business day after a Conversion Date.

                  (ii) The Holder shall effect conversions by delivering to the
Obligor a completed notice in the form attached hereto as Exhibit A ("Conversion
Notice"). The date on which a Conversion Notice is delivered is the "Conversion
Date." The Holder is required to physically surrender this Note to the Obligor
in order to effect conversions. Conversions hereunder shall have the effect of
lowering the outstanding principal amount of this Note plus all accrued and
unpaid interest thereon in an amount equal to the applicable conversion. The
Holder and the Obligor shall maintain records showing the principal amount
converted and the date of such conversions.

                                       4
<PAGE>

         (b) CONVERSION PRICE AND ADJUSTMENTS TO CONVERSION PRICE.

                  (i) The Holder shall be entitled to convert, at its sole
option, at any time a portion or all amounts of principal and interest due and
outstanding under this Note into that number of Conversion Shares to which the
Holder is entitled under Section 3(a)(i) at a price of $2.50 per share of common
stock (the "Conversion Price"). The Conversion Price may be adjusted pursuant to
the other terms of this Note. In the event that the outstanding principal and
interest on the Note on the Conversion Date are less than the product of the
Conversion Price times the Conversion Shares purchasable by the Holder, the
Holder shall have the right to pay the difference to the company in cash on the
Conversion Date.

                  (ii) If the Obligor, at any time while this Note is
outstanding, shall (a) 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 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 Obligor, then the 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 Obligor, at any time while this Note is
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holder) entitling them to subscribe for or purchase shares
of Common Stock, at a price per share less than the Conversion Price, 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 the Conversion Price. 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.

<PAGE>

                  (iv) If the Obligor at any time while this Note is 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, 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 Obligor shall notify the Holder in writing, no later than two (2) Business
Days 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 issuances
and exercises of options, warrants or stock grants to purchase shares of Common
Stock issued for compensatory purposes pursuant to any of the Obligor's stock
option or stock purchase plans.

                  (v) 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 at any time while this Note is outstanding,
the Holder shall have the right thereafter to, at its 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 Note, 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 Holder of this Note shall be entitled upon such event
to receive such amount of securities, cash or property as the shares of the
Common Stock of the Obligor 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 Note could have been converted immediately prior to
such reclassification or share exchange would have been entitled, or (B) require
the Obligor to prepay the outstanding principal amount of this Note, plus all
interest and other amounts due and payable thereon. The entire prepayment price
shall be paid in cash. This provision shall similarly apply to successive
reclassifications or share exchanges.

<PAGE>

                  (vi) The Obligor shall maintain a share reserve of not less
than one hundred percent (100%) of the shares of Common Stock issuable upon
conversion of this Note; and within three (3) Business Days following the
receipt by the Obligor of a Holder's notice that such minimum number of
Underlying Shares is not so reserved, the Obligor shall promptly reserve a
sufficient number of shares of Common Stock to comply with such requirement.

                  (vii)    All  calculations  under this  Section 3 shall be
rounded up to the nearest $0.001 or whole share.

                  (viii) Whenever the Conversion Price is adjusted pursuant to
Section 3 hereof, the Obligor shall promptly mail to the Holder a notice setting
forth the Conversion Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.

                  (ix) If at any time while this Note is outstanding (A) the
Obligor shall declare a dividend (or any other distribution) on the Common
Stock; (B) the Obligor shall declare a special nonrecurring cash dividend on or
a redemption of the Common Stock; (C) the Obligor 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 except
pursuant to the Rights Plan; (D) the approval of any stockholders of the Obligor
shall be required in connection with any reclassification of the Common Stock,
any consolidation or merger to which the Obligor is a party, any sale or
transfer of all or substantially all of the assets of the Obligor, or any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; or (E) the Obligor shall authorize the voluntary
or involuntary dissolution, liquidation or winding up of the affairs of the
Obligor; then, in each case, the Obligor shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Note, and shall cause
to be mailed to the Holder at its last address as it shall appear upon the stock
books of the Obligor, at least twenty (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. The Holder is
entitled to convert this Note during the 20-day calendar period commencing the
date of such notice to the effective date of the event triggering such notice.

                                       7
<PAGE>

         (x) In case of any (1) merger or consolidation of the Obligor or any
subsidiary of the Obligor with or into another Person, or (2) sale by the
Obligor of more than one-half of the assets of the Obligor in one or a series of
related transactions, at any time while this Note is outstanding, a Holder shall
have the right to (A) convert the aggregate amount of this Note 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 this
Note could have been converted immediately prior to such merger, consolidation
or sales would have been entitled, or (B) in the case of a merger or
consolidation, require the surviving entity to issue to the Holder a convertible
Note with a principal amount equal to the aggregate principal amount of this
Note then held by such Holder, plus all accrued and unpaid interest and other
amounts owing thereon, which such newly issued convertible Note shall have terms
identical (including with respect to conversion) to the terms of this Note, and
shall be entitled to all of the rights and privileges of the Holder of this Note
set forth herein and the agreements pursuant to which this Notes were issued. In
the case of clause (B), the conversion price applicable for the newly issued
shares of convertible preferred stock or convertible Notes 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 Holder 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.

         (c) OTHER PROVISIONS.

                  (i) The Obligor 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 this Note and payment of
interest on this Note, each as herein provided, free from preemptive rights or
any other actual contingent purchase rights of persons other than the Holder,
not less than such number of shares of the Common Stock as shall (subject to any
additional requirements of the Obligor as to reservation of such shares set
forth in this Note) be issuable (taking into account the adjustments and
restrictions of Section 3(c) upon the conversion of the outstanding principal
amount of this Note and payment of interest hereunder. The Obligor 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.

                  (ii) Upon a conversion hereunder the Obligor 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 Conversion Price. If the Obligor
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.

                  (iii) The issuance of certificates for shares of the Common
Stock on conversion of this Note shall be made without charge to the Holder
thereof for any documentary stamp or similar taxes that may be payable in
respect of the issue or delivery of such certificate, provided that the Obligor
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 Note so converted and
the Obligor 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 Obligor the amount of such tax or shall have established to the
satisfaction of the Obligor that such tax has been paid.

                  (iv) Nothing herein shall limit a Holder's right to pursue
actual damages or declare an Event of Default pursuant to Section 2 herein for
the Obligor 's failure to deliver certificates representing shares of Common
Stock upon conversion within the period specified herein and the 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 Holder
from seeking to enforce damages pursuant to any other Section hereof or under
applicable law.

<PAGE>

                  (v) In addition to any other rights available to the Holder,
if the Obligor fails to deliver to the Holder such certificate or certificates
pursuant to Section 3(a)(i), and if after such tenth (10th) Business 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
Obligor 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 a Note in the 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 Obligor timely complied with
its delivery requirements. 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 Notes 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 Obligor shall be required to pay
the Holder $1,000. The Holder shall provide the Obligor written notice
indicating the amounts payable to the Holder in respect of the Buy-In.

         SECTION 4. NOTICES. Any notices, consents, waivers or other
communications required or permitted to be given under the terms hereof must be

         SECTION 12. WAIVERS LIMITED. Any waiver by the Holder of a breach of
any provision of this Note shall not operate as or be construed to be a waiver
of any other breach of such provision or of any breach of any other provision of
this Note. The failure of the Holder to insist upon strict adherence to any term
of this Note on one or more occasions shall not be considered a waiver or

hereunder shall violate applicable laws governing usury, the applicable rate of
interest due hereunder shall automatically be lowered to equal the maximum
permitted rate of interest. The Obligor covenants (to the extent that it may
lawfully do so) that it shall not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law or other law which would prohibit or forgive the Obligor from
paying all or any portion of the principal of or interest on this Note as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this indenture, and the
Obligor (to the extent it may lawfully do so) hereby expressly waives all
benefits or advantage of any such law, and covenants that it will not, by resort
to any such law, hinder, delay or impeded the execution of any power herein
granted to the Holder, but will suffer and permit the execution of every such as
though no such law has been enacted.

         SECTION 14. BUSINESS DAY. Whenever any payment or other obligation
hereunder shall be due on a day other than a Business Day, such payment shall be
made on the next succeeding Business Day.

         SECTION 15. CERTAIN WAIVERS. THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE THE RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN
RESPECT OF ANY LITIGATION BASED HEREON OR ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS AGREEMENT OR ANY TRANSACTION DOCUMENT OR ANY COURSE OF CONDUCT, COURSE
OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES' ACCEPTANCE OF THIS
AGREEMENT.
