___________________________________________ or registered assigns ("HOLDER") the
amount set out above as the Original Principal Amount (as reduced pursuant to
the terms hereof pursuant to redemption, conversion or otherwise, the
"PRINCIPAL") when due, whether upon the Maturity Date (as defined below), on any
Installment Date with respect to the Installment Amount due on such Installment

case in accordance with the terms hereof) and to pay interest ("INTEREST") on
any outstanding Principal at the applicable Interest Rate (as defined below)
from the date set out above as the Issuance Date (the "ISSUANCE DATE") until the

herein are defined in Section 30.

<PAGE>

         (1) PAYMENTS OF PRINCIPAL. On each Installment Date, the Company shall
pay to the Holder an amount equal to the Installment Amount due on such
Installment Date in accordance with Section 8. On the Maturity Date, the Company
shall pay to the Holder an amount in cash representing all outstanding
Principal, accrued and unpaid Interest and accrued and unpaid Late Charges (as
defined in Section 26), if any, on such Principal and Interest. The "MATURITY
DATE" shall be July 31, 2008, as may be extended at the option of the Holder (i)
in the event that, and for so long as, an Event of Default (as defined in
Section 4(a)) shall have occurred and be continuing on the Maturity Date (as may
be extended pursuant to this Section 1) or any event shall have occurred and be
continuing on the Maturity Date (as may be extended pursuant to this Section 1)
that with the passage of time and the failure to cure would result in an Event
of Default, (ii) through the date that is ten (10) Business Days after the
consummation of a Change of Control in the event that a Change of Control is
publicly announced or a Change of Control Notice (as defined in Section 5(b)) is
delivered prior to the Maturity Date, and (iii) to the latest designated date
for repayment upon the deferral of payment of any Installment Amount in
accordance with Section 8(d). Other than as specifically permitted by this Note,
the Company may not prepay any portion of the outstanding Principal, accrued and
unpaid interest or accrued and unpaid Late Charges on Principal and Interest, if
any.

         (2) INTEREST; INTEREST RATE. Interest on this Note shall commence
accruing on the Issuance Date and shall be computed on the basis of a 360-day
year comprised of twelve (12) thirty (30) day months and shall be payable in
arrears for each Calendar Quarter on the first (1st) day of the succeeding
Calendar Quarter during the period beginning on the Issuance Date and ending on,
and including, the Maturity Date (each, an "INTEREST DATE") with the first (1st)
Interest Date being October 1, 2006. Interest shall be payable on each Interest
Date, to the record holder of this Note on the applicable Interest Date, and to
the extent that any Principal amount of this Note is converted prior to such
Interest Date, accrued and unpaid Interest with respect to such converted
Principal amount and accrued and unpaid Late Charges, if any, with respect to
such Principal and Interest shall be payable by way of inclusion of such
Interest and Late Charges in the Conversion Amount, in accordance with Section
3(b)(i). From and after the occurrence and during the continuance of an Event of
Default, the Interest Rate shall be increased to fifteen percent (15.0%). In the
event that such Event of Default is subsequently cured, the adjustment referred
to in the preceding sentence shall cease to be effective as of the date of such
cure; provided that the Interest as calculated and unpaid at such increased rate
during the continuance of such Event of Default shall continue to apply to the
extent relating to the days after the occurrence of such Event of Default
through and including the date of cure of such Event of Default.

         (3) CONVERSION OF NOTES. This Note shall be convertible into shares of
the Company's common stock, par value $0.001 per share (the "COMMON STOCK"), on
the terms and conditions set forth in this Section 3.

                                      -2-

<PAGE>

             (a) CONVERSION RIGHT. Subject to the provisions of Section 3(d) and
subject to the Company's right to elect to pay accrued and unpaid Interest and
Late Charges, if any, in cash as set forth in Section 3(c)(i), at any time or
times on or after the Issuance Date, the Holder shall be entitled to convert any
portion of the outstanding and unpaid Conversion Amount (as defined below) into
fully paid and nonassessable shares of Common Stock in accordance with Section
3(c), at the Conversion Rate (as defined below). The Company shall not issue any
fraction of a share of Common Stock upon any conversion. If the issuance would
result in the issuance of a fraction of a share of Common Stock, the Company
shall round such fraction of a share of Common Stock up to the nearest whole
share. The Company shall pay any and all transfer, stamp and similar taxes that
may be payable with respect to the issuance and delivery of Common Stock upon
conversion of any Conversion Amount.

             (b) CONVERSION RATE. Subject to the Company's right to elect to pay
accrued and unpaid Interest and Late Charges, if any, in cash as set forth in
Section 3(c)(i), the number of shares of Common Stock issuable upon conversion
of any Conversion Amount pursuant to Section 3(a) shall be determined by
dividing (x) such Conversion Amount by (y) the Conversion Price (the "CONVERSION
RATE").

                  (i) "CONVERSION AMOUNT" means the sum of (A) the portion of
the Principal to be converted, redeemed or otherwise with respect to which this
determination is being made, (B) accrued and unpaid Interest with respect to
such Principal and (C) accrued and unpaid Late Charges with respect to such
Principal and Interest.

                  (ii) "CONVERSION PRICE" means, as of any Conversion Date (as
defined below) or other date of determination, $0.43948, subject to adjustment
as provided herein.

             (c) MECHANICS OF CONVERSION.

                  (i) OPTIONAL CONVERSION. To convert any Conversion Amount into
shares of Common Stock on any Trading Day (a "CONVERSION DATE"), the Holder
shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior
to 11:59 p.m., New York Time, on a Business Day, a copy of an executed notice of
conversion in the form attached hereto as EXHIBIT I (the "CONVERSION NOTICE") to
the Company and (B) if required by Section 3(c)(iii), surrender this Note to a
common carrier for delivery to the Company as soon as practicable on or
following such date (or an indemnification undertaking with respect to this Note
in the case of its loss, theft or destruction). Accrued and unpaid Interest and
Late Charges, if any, on any Principal portion of the Conversion Amount being
converted shall be payable to the record holder of this Note on the applicable
Share Delivery Date (as defined below) in shares of Common Stock so long as
there has been no Equity Conditions Failure; provided however, that the Company
may, at its option following notice to the Holder, pay accrued and unpaid
Interest and/or Late Charges, if any, on any Principal portion of the Conversion
Amount being converted on the applicable Share Delivery Date in cash ("CASH
INTEREST/CHARGES"). On or before the second (2nd) Trading Day following the date
of receipt of a Conversion Notice, the Company shall transmit by facsimile a
confirmation of receipt of such Conversion Notice to the Holder and the
Company's transfer agent (the "TRANSFER AGENT"). On or before the third (3rd)
Business Day following the date of receipt of a Conversion Notice (the "SHARE
DELIVERY DATE"), the Company shall (1) (x) provided that the Transfer Agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer Program and that securities are to be issued without legends pursuant
to Section 2(g) of the Securities Purchase Agreement, credit such aggregate

                                      -3-

<PAGE>

number of shares of Common Stock (including any shares of Common Stock delivered
in respect of Interest and/or Late Charges) to which the Holder shall be
entitled to the Holder's or its designee's balance account with DTC through its
Deposit Withdrawal Agent Commission system or (y) if the Transfer Agent is not
participating in the DTC Fast Automated Securities Transfer Program or if
securities are to be issued with legends pursuant to Section 2(g) of the
Securities Purchase Agreement, issue and deliver to the address as specified in
the Conversion Notice, a certificate, registered in the name of the Holder or
its designee, for the number of shares of Common Stock to which the Holder shall
be entitled and (2) if the Company has elected to pay Cash Interest/Charges, pay
to the Holder in cash an amount equal to the accrued and unpaid Interest and/or
Late Charges, if any, on the Principal portion of the Conversion Amount up to
and including the Conversion Date. If this Note is physically surrendered for
conversion pursuant to Section 3(c)(iii) and the outstanding Principal of this
Note is greater than the Principal portion of the Conversion Amount being
converted, then the Company shall as soon as practicable and in no event later
than five (5) Business Days after receipt of this Note and at its own expense,
issue and deliver to the holder a new Note (in accordance with Section 20(d))
representing the outstanding Principal not converted. The Person or Persons
entitled to receive the shares of Common Stock issuable upon a conversion of
this Note shall be treated for all purposes as the record holder or holders of
such shares of Common Stock on the Conversion Date. In the event of a partial
conversion of this Note pursuant hereto, the Principal amount and Interest
converted shall be deducted from the Installment Amounts relating to the
Installment Dates as set forth in the Conversion Notice.

                  (ii) COMPANY'S FAILURE TO TIMELY CONVERT. If the Company shall
fail to issue a certificate to the Holder or credit the Holder's balance account
with DTC, as applicable, for the number of shares of Common Stock to which the
Holder is entitled upon conversion of any Conversion Amount on or prior to the
date which is five (5) Trading Days after the Conversion Date (a "CONVERSION
FAILURE"), then (A) the Company shall pay damages to the Holder for each Trading
Day of such Conversion Failure in an amount equal to 1.5% of the product of (I)
the sum of the number of shares of Common Stock not issued to the Holder on or
prior to the Share Delivery Date and to which the Holder is entitled, and (II)
the Closing Sale Price of the Common Stock on the Share Delivery Date and (B)
the Holder, upon written notice to the Company, may void its Conversion Notice
with respect to, and retain or have returned, as the case may be, any portion of
this Note that has not been converted pursuant to such Conversion Notice;
PROVIDED that the voiding of a Conversion Notice shall not affect the Company's
obligations to make any payments which have accrued prior to the date of such
notice pursuant to this Section 3(c)(ii) or otherwise. In addition to the
foregoing, if within three (3) Trading Days after the Company's receipt of the
facsimile copy of a Conversion Notice the Company shall fail to issue and
deliver a certificate to the Holder or credit the Holder's balance account with
DTC for the number of shares of Common Stock to which the Holder is entitled
upon such holder's conversion of any Conversion Amount, and if on or after such
Trading Day the Holder purchases (in an open market transaction or otherwise)
Common Stock to deliver in satisfaction of a sale by the Holder of the number of
shares of Common Stock issuable upon such conversion that the Holder anticipated
receiving from the Company (a "BUY-IN"), then the Company shall, within five (5)
Trading Days after the Holder's request and in the Holder's discretion, either
(A) pay cash to the Holder in an amount equal to the Holder's total purchase
price (including brokerage commissions and other out of pocket expenses, if any)
for such number of shares of Common Stock so purchased (the "BUY-IN PRICE"), at
which point the Company's obligation to deliver such certificate (and to issue
such Common Stock) shall terminate, or (B) promptly honor its obligation to
deliver to the Holder a certificate or certificates representing such Common
Stock and pay cash to the Holder in an amount equal to the excess (if any) of
the Buy-In Price over the product of (1) such number of shares of Common Stock,
times (2) the Closing Bid Price on the Conversion Date.

<PAGE>

                  (iii) BOOK-ENTRY. Notwithstanding anything to the contrary set
forth herein, upon conversion of any portion of this Note in accordance with the
terms hereof, the Holder shall not be required to physically surrender this Note
to the Company unless (A) the full Conversion Amount represented by this Note is
being converted or (B) the Holder has provided the Company with prior written
notice (which notice may be included in a Conversion Notice) requesting
reissuance of this Note upon physical surrender of this Note. The Holder and the
Company shall maintain records showing the Principal, Interest and Late Charges
converted and the dates of such conversions or shall use such other method,
reasonably satisfactory to the Holder and the Company, so as not to require
physical surrender of this Note upon conversion (except as required above).

                  (iv) PRO RATA CONVERSION; DISPUTES. In the event that the
Company receives a Conversion Notice from more than one holder of Notes for the
same Conversion Date and the Company can convert some, but not all, of such
portions of the Notes submitted for conversion, the Company, subject to Section
3(d), shall convert from each holder of Notes electing to have Notes converted
on such date a pro rata amount of such holder's portion of its Notes submitted
for conversion based on the principal amount of Notes submitted for conversion
on such date by such holder relative to the aggregate principal amount of all
Notes submitted for conversion on such date. In the event of a dispute as to the
number of shares of Common Stock issuable to the Holder in connection with a
conversion of this Note, the Company shall issue to the Holder the number of
shares of Common Stock not in dispute and resolve such dispute in accordance
with Section 25.

             (d) LIMITATIONS ON CONVERSIONS.

                  (i) BENEFICIAL OWNERSHIP. The Company shall not effect any
conversion of this Note, and the Holder of this Note shall not have the right to
convert any portion of this Note pursuant to Section 3(a), to the extent that
after giving effect to such conversion, the Holder (together with the Holder's
affiliates) would beneficially own in excess of 4.99% (the "MAXIMUM PERCENTAGE")
of the number of shares of Common Stock outstanding immediately after giving
effect to such conversion. For purposes of the foregoing sentence, the number of
shares of Common Stock beneficially owned by the Holder and its affiliates shall
include the number of shares of Common Stock issuable upon conversion of this
Note with respect to which the determination of such sentence is being made, but
shall exclude the number of shares of Common Stock which would be issuable upon
(A) conversion of the remaining, nonconverted portion of this Note beneficially
owned by the Holder or any of its affiliates and (B) exercise or conversion of
the unexercised or nonconverted portion of any other securities of the Company
(including, without limitation, any Other Notes or warrants) subject to a
limitation on conversion or exercise analogous to the limitation contained
herein beneficially owned by the Holder or any of its affiliates. Except as set
forth in the preceding sentence, for purposes of this Section 3(d)(i),
beneficial ownership shall be calculated in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "1934 ACT"). For purposes of
this Section 3(d)(i), in determining the number of outstanding shares of Common
Stock, the Holder may rely on the number of outstanding shares of Common Stock

                                      -5-

<PAGE>

as reflected in (x) the Company's most recent Form 10-K, Form 10-KSB, Form 10-Q,
Form 10-QSB, Form 8-K or other public filing with the Securities Exchange
Commission, as the case may be (y) a more recent public announcement by the
Company or (z) any other notice by the Company or the Transfer Agent setting
forth the number of shares of Common Stock outstanding. For any reason at any
time, upon the written or oral request of the Holder, the Company shall within
two (2) Business Days confirm orally and in writing to the Holder the number of
shares of Common Stock then outstanding. In any case, the number of outstanding
shares of Common Stock shall be determined after giving effect to the conversion
or exercise of securities of the Company, including this Note, by the Holder or
its affiliates since the date as of which such number of outstanding shares of
Common Stock was reported. By written notice to the Company, the Holder may
increase or decrease the Maximum Percentage to any other percentage not in
excess of 9.99% specified in such notice; provided that (i) any such increase
will not be effective until the sixty-first (61st) day after such notice is
delivered to the Company, and (ii) any such increase or decrease will apply only
to the Holder and not to any other holder of Notes.

                  (ii) ELIGIBLE MARKET REGULATION. The Company shall not be
obligated to issue any shares of Common Stock upon conversion of this Note if
the issuance of such shares of Common Stock would exceed the aggregate number of
shares of Common Stock which the Company may issue upon conversion or exercise,
as applicable, of the Notes and Warrants without breaching the Company's
obligations under the rules or regulations of any applicable Eligible Market
(the "EXCHANGE CAP"), except that such limitation shall not apply in the event
that the Company (A) obtains the approval of its stockholders as required by the
applicable rules of such Eligible Market for issuances of Common Stock in excess
of such amount or (B) obtains a written opinion from outside counsel to the
Company that such approval is not required, which opinion shall be reasonably
satisfactory to the Required Holders. Until such approval or written opinion is
obtained, no purchaser of the Notes pursuant to the Securities Purchase
Agreement (the "PURCHASERS") shall be issued in the aggregate, upon conversion
or exercise or otherwise, as applicable, of Notes or Warrants, shares of Common
Stock in an amount greater than the product of the Exchange Cap multiplied by a
fraction, the numerator of which is the principal amount of Notes issued to a
Purchaser pursuant to the Securities Purchase Agreement on the Closing Date and
the denominator of which is the aggregate principal amount of all Notes issued
to the Purchasers pursuant to the Securities Purchase Agreement on the Closing
Date (with respect to each Purchaser, the "EXCHANGE CAP ALLOCATION"). In the
event that any Purchaser shall sell or otherwise transfer any of such
Purchaser's Notes, the transferee shall be allocated a pro rata portion of such
Purchaser's Exchange Cap Allocation, and the restrictions of the prior sentence
shall apply to such transferee with respect to the portion of the Exchange Cap
Allocation allocated to such transferee. In the event that any holder of Notes
shall convert all of such holder's Notes into a number of shares of Common Stock
which, in the aggregate, is less than such holder's Exchange Cap Allocation,
then the difference between such holder's Exchange Cap Allocation and the number
of shares of Common Stock actually issued to such holder shall be allocated to
the respective Exchange Cap Allocations of the remaining holders of Notes on a
pro rata basis in proportion to the aggregate principal amount of the Notes then
held by each such holder.

         (4) RIGHTS UPON EVENT OF DEFAULT.

             (a) EVENT OF DEFAULT. Each of the following events shall constitute
an "EVENT OF DEFAULT":

after the applicable Effectiveness Deadline (as defined in the Registration
Rights Agreement), or, while the applicable Registration Statement is required
to be maintained effective pursuant to the terms of the Registration Rights
Agreement, the effectiveness of the applicable Registration Statement lapses for
any reason (including, without limitation, the issuance of a stop order) or is
unavailable to any holder of the Notes for sale of all of such holder's
Registrable Securities (as defined in the Registration Rights Agreement) in
accordance with the terms of the Registration Rights Agreement, and such lapse
or unavailability continues for a period of ten (10) consecutive days or for
more than an aggregate of thirty (30) days in any 365-day period (other than
days during an Allowable Grace Period (as defined in the Registration Rights
Agreement));

                  (ii) the suspension from trading or failure of the Common

request for conversion of any Notes into shares of Common Stock that is tendered
in accordance with the provisions of the Notes, other than pursuant to Section
3(d);

conversion set forth in Section 3(d) or otherwise);

                  (v) the Company's failure to pay to the Holder any amount of

payments or amounts hereunder) or any other Transaction Document (as defined in
the Securities Purchase Agreement) or any other agreement, document, certificate
or other instrument delivered in connection with the transactions contemplated
hereby and thereby to which the Holder is a party, except, in the case of a
failure to pay Interest and Late Charges when and as due, in which case only if
such failure continues for a period of at least five (5) Business Days;

                                      -7-

<PAGE>

                  (vi) any default under, redemption of or acceleration prior to

any Other Notes;

                  (vii) the Company or any of its Subsidiaries, pursuant to or

against it in an involuntary case, (C) consents to the appointment of a

any of its Subsidiaries in an involuntary case, (B) appoints a Custodian of the
Company or any of its Subsidiaries or (C) orders the liquidation of the Company
or any of its Subsidiaries;

                  (ix) a final judgment or judgments for the payment of money
aggregating in excess of $350,000 are rendered against the Company or any of its
Subsidiaries and which judgments are not, within sixty (60) days after the entry
thereof, bonded, discharged or stayed pending appeal, or are not discharged
within sixty (60) days after the expiration of such stay; provided, however,
that any judgment which is covered by insurance or an indemnity from a credit
worthy party shall not be included in calculating the $350,000 amount set forth
above so long as the Company provides the Holder a written statement from such
insurer or indemnity provider (which written statement shall be reasonably
satisfactory to the Holder) to the effect that such judgment is covered by
insurance or an indemnity and the Company will receive the proceeds of such
insurance or indemnity within thirty (30) days of the issuance of such judgment;

                  (x) the Company breaches any representation, warranty,
covenant or other term or condition of any Transaction Document, except, in the
case of a breach of a covenant or other term or condition of any Transaction

least ten (10) consecutive Business Days;

                  (xi) any breach or failure in any respect to comply with
either of Sections 8 or 16 of this Note or Section 4(q) of the Securities

                  (xii) any Event of Default (as defined in the Other Notes)

             (b) REDEMPTION RIGHT. Upon the occurrence of an Event of Default
with respect to this Note, the Company shall within two (2) Business Days
deliver written notice thereof via facsimile and overnight courier (an "EVENT OF
DEFAULT NOTICE") to the Holder. At any time after the earlier of the Holder's
receipt of an Event of Default Notice and the Holder becoming aware of an Event
of Default, the Holder may require the Company to redeem all or any portion of
this Note by delivering written notice thereof (the "EVENT OF DEFAULT REDEMPTION
NOTICE") to the Company, which Event of Default Redemption Notice shall indicate
the Conversion Amount of this Note the Holder is electing to require the Company

                                      -8-

<PAGE>

to redeem. Each portion of this Note subject to redemption by the Company
pursuant to this Section 4(b) shall be redeemed by the Company at a price equal
to the greater of (i) the product of (A) the Conversion Amount to be redeemed
and (B) the Redemption Premium and (ii) the product of (A) the product of (1)
the Conversion Rate with respect to such sum of the Conversion Amount in effect
at such time as the Holder delivers an Event of Default Redemption Notice and
(2) the Equity Value Redemption Premium and (B) the lesser of (1) the Closing
Sale Price of the Common Stock on the date immediately preceding such Event of
Default, (2) the Closing Sale Price of the Common Stock on the date immediately
after such Event of Default and (3) the Closing Sale Price of the Common Stock
on the date the Holder delivers the Event of Default Redemption Notice (the
"EVENT OF DEFAULT REDEMPTION PRICE"). Redemptions required by this Section 4(b)
shall be made in accordance with the provisions of Section 14. To the extent
redemptions required by this Section 4(b) are deemed or determined by a court of
competent jurisdiction to be prepayments of the Note by the Company, such
redemptions shall be deemed to be voluntary prepayments. In the event of a
partial redemption of this Note pursuant hereto, the principal amount redeemed
shall be deducted from the Installment Amounts relating to the applicable
Installment Dates as set forth in the Event of Default Redemption Notice. The
parties hereto agree that in the event of the Company's redemption of any
portion of the Note under this Section 4(b), the Holder's damages would be
uncertain and difficult to estimate because of the parties' inability to predict
future interest rates and the uncertainty of the availability of a suitable
substitute investment opportunity for the Holder. Accordingly, any Redemption
Premium due under this Section 4(b) is intended by the parties to be, and shall
be deemed, a reasonable estimate of the Holder's actual loss of its investment
opportunity and not as a penalty.

         (5) RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.

             (a) ASSUMPTION. The Company shall not enter into or be party to a
Fundamental Transaction unless (i) the Successor Entity assumes in writing all
of the obligations of the Company under this Note and the other Transaction
Documents in accordance with the provisions of this Section 5(a) pursuant to
written agreements in form and substance reasonably satisfactory to the Required
Holders and approved by the Required Holders prior to such Fundamental
Transaction, including agreements to deliver to each holder of Notes in exchange
for such Notes a security of the Successor Entity evidenced by a written
instrument substantially similar in form and substance to the Notes, including,
without limitation, having a principal amount and interest rate equal to the
principal amounts and the interest rates of the Notes then outstanding held by
such holder, having similar conversion rights and having similar ranking to the
Notes, and satisfactory to the Required Holders and (ii) the Successor Entity
(including its Parent Entity) is a publicly traded corporation whose common
stock is quoted on or listed for trading on an Eligible Market (a "PUBLIC
SUCCESSOR ENTITY"). Upon the occurrence of any Fundamental Transaction, the
Successor Entity shall succeed to, and be substituted for (so that from and
after the date of such Fundamental Transaction, the provisions of this Note
referring to the "Company" shall refer instead to the Successor Entity), and may
exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Note with the same effect as if such
Successor Entity had been named as the Company herein. Upon consummation of the
Fundamental Transaction, the Successor Entity shall deliver to the Holder
confirmation that there shall be issued upon conversion or redemption of this

                                      -9-

<PAGE>

Note at any time after the consummation of the Fundamental Transaction, in lieu
of the shares of the Company's Common Stock (or other securities, cash, assets
or other property) issuable upon the conversion or redemption of the Notes prior
to such Fundamental Transaction, such shares of the publicly traded common stock
(or their equivalent) of the Successor Entity (including its Parent Entity), as
adjusted in accordance with the provisions of this Note. The provisions of this
Section shall apply similarly and equally to successive Fundamental Transactions
and shall be applied without regard to any limitations on the conversion or
redemption of this Note.

             (b) REDEMPTION RIGHT. No sooner than fifteen (15) days nor later
than ten (10) days prior to the consummation of a Change of Control, but not
prior to the public announcement of such Change of Control, the Company shall
deliver written notice thereof via facsimile and overnight courier to the Holder
(a "CHANGE OF CONTROL NOTICE"). At any time during the period beginning after
the Holder's receipt of a Change of Control Notice and ending twenty (20)
Trading Days after the date of the consummation of such Change of Control, the
Holder may require the Company to redeem all or any portion of this Note by
delivering written notice thereof ("CHANGE OF CONTROL REDEMPTION NOTICE") to the
Company, which Change of Control Redemption Notice shall indicate the Conversion
Amount the Holder is electing to require the Company to redeem. The portion of
this Note subject to redemption pursuant to this Section 5 shall be redeemed by
the Company in cash at a price equal to the greater of (i) 150% of the
Conversion Amount being redeemed and (ii) the product of (A) the product of (1)
the Equity Value Redemption Premium and (2) the Conversion Amount being redeemed
multiplied by (B) the quotient determined by dividing (x) the aggregate cash
consideration and the aggregate cash value of any non-cash consideration per
Common Share to be paid to the holders of the Common Shares upon consummation of
the Change of Control (any such non-cash consideration consisting of marketable
securities to be valued at the higher of (x) the Closing Sale Price of such
securities as of the Trading Day immediately prior to the consummation of such
Change of Control, (y) the Closing Sale Price as of the Trading Day immediately
following the public announcement of such proposed Change of Control and (z) the
Closing Sale Price as of the Trading Day immediately prior to the public
announcement of such proposed Change of Control) by (y) the Conversion Price
(the "CHANGE OF CONTROL REDEMPTION PRICE"). Redemptions required by this Section
5 shall be made in accordance with the provisions of Section 14 and shall have
priority to payments to stockholders in connection with a Change of Control. To
the extent redemptions required by this Section 5(b) are deemed or determined by
a court of competent jurisdiction to be prepayments of the Note by the Company,
such redemptions shall be deemed to be voluntary prepayments. Notwithstanding
anything to the contrary in this Section 5, but subject to Section 3(d), until
the Change of Control Redemption Price (together with any interest thereon) is
paid in full, the Conversion Amount submitted for redemption under this Section
5(c) (together with any interest thereon) may be converted, in whole or in part,
by the Holder into Common Stock pursuant to Section 3. In the event of a partial
redemption of this Note pursuant hereto, the principal amount redeemed shall be
deducted from the Installment Amounts relating to the applicable Installment
Dates as set forth in the Change of Control Redemption Notice. The parties
hereto agree that in the event of the Company's redemption of any portion of the
Note under this Section 5(b), the Holder's damages would be uncertain and
difficult to estimate because of the parties' inability to predict future
interest rates and the uncertainty of the availability of a suitable substitute
investment opportunity for the Holder. Accordingly, any Change of Control
redemption premium due under this Section 5(b) is intended by the parties to be,
and shall be deemed, a reasonable estimate of the Holder's actual loss of its
investment opportunity and not as a penalty.

                                      -10-

         (6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

             (a) PURCHASE RIGHTS. If at any time the Company grants, issues or
sells any Options, Convertible Securities or rights to purchase stock, warrants,
securities or other property pro rata to the record holders of any class of
Common Stock (the "PURCHASE RIGHTS"), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock acquirable upon complete conversion of this
Note (without taking into account any limitations or restrictions on the
convertibility of this Note) immediately before the date on which a record is
taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of Common Stock are to
be determined for the grant, issue or sale of such Purchase Rights.

             (b) OTHER CORPORATE EVENTS. In addition to and not in substitution
for any other rights hereunder, prior to the consummation of any Fundamental
Transaction pursuant to which holders of shares of Common Stock are entitled to
receive securities or other assets with respect to or in exchange for shares of
Common Stock (a "CORPORATE EVENT"), the Company shall make appropriate provision
to insure that the Holder will thereafter have the right to receive upon a
conversion of this Note, at the Holder's option, (i) in addition to the shares
of Common Stock receivable upon such conversion, such securities or other assets
to which the Holder would have been entitled with respect to such shares of
Common Stock had such shares of Common Stock been held by the Holder upon the
consummation of such Corporate Event (without taking into account any
limitations or restrictions on the convertibility of this Note) or (ii) in lieu
of the shares of Common Stock otherwise receivable upon such conversion, such
securities or other assets received by the holders of shares of Common Stock in
connection with the consummation of such Corporate Event in such amounts as the
Holder would have been entitled to receive had this Note initially been issued
with conversion rights for the form of such consideration (as opposed to shares
of Common Stock) at a conversion rate for such consideration commensurate with
the Conversion Rate. Provision made pursuant to the preceding sentence shall be
in a form and substance satisfactory to the Required Holders. The provisions of
this Section shall apply similarly and equally to successive Corporate Events
and shall be applied without regard to any limitations on the conversion or
redemption of this Note.

         (7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

             (a) ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF COMMON STOCK.
If and whenever on or after the Subscription Date, the Company issues or sells,
or in accordance with this Section 7(a) is deemed to have issued or sold, any
shares of Common Stock (including the issuance or sale of shares of Common Stock
owned or held by or for the account of the Company, but excluding shares of
Common Stock deemed to have been issued or sold by the Company in connection
with any Excluded Security) for a consideration per share (the "NEW ISSUANCE
PRICE") less than a price (the "APPLICABLE PRICE") equal to the Conversion Price
in effect immediately prior to such issue or sale (the foregoing a "DILUTIVE
ISSUANCE"), then immediately after such Dilutive Issuance the Conversion Price
then in effect shall be reduced to an amount equal to the New Issuance Price.
For purposes of determining the adjusted Conversion Price under this Section
7(a), the following shall be applicable:

                                      -11-

<PAGE>

                  (i) ISSUANCE OF OPTIONS. If the Company in any manner grants
or sells any Options and the lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon conversion
or exchange or exercise of any Convertible Securities issuable upon exercise of
such Option is less than the Applicable Price, then such share of Common Stock
shall be deemed to be outstanding and to have been issued and sold by the
Company at the time of the granting or sale of such Option for such price per
share. For purposes of this Section 7(a)(i), the "lowest price per share for
which one share of Common Stock is issuable upon the exercise of any such Option
or upon conversion or exchange or exercise of any Convertible Securities
issuable upon exercise of such Option" shall be equal to the sum of the lowest
amounts of consideration (if any) received or receivable by the Company with
respect to any one share of Common Stock upon granting or sale of the Option,
upon exercise of the Option and upon conversion or exchange or exercise of any
Convertible Security issuable upon exercise of such Option. No further
adjustment of the Conversion Price shall be made upon the actual issuance of
such share of Common Stock or of such Convertible Securities upon the exercise
of such Options or upon the actual issuance of such Common Stock upon conversion
or exchange or exercise of such Convertible Securities.

                  (ii) ISSUANCE OF CONVERTIBLE SECURITIES. If the Company in any
manner issues or sells any Convertible Securities and the lowest price per share
for which one share of Common Stock is issuable upon such conversion or exchange
or exercise thereof is less than the Applicable Price, then such share of Common
Stock shall be deemed to be outstanding and to have been issued and sold by the
Company at the time of the issuance or sale of such Convertible Securities for
such price per share. For the purposes of this Section 7(a)(ii), the "lowest
price per share for which one share of Common Stock is issuable upon such
conversion or exchange or exercise" shall be equal to the sum of the lowest
amounts of consideration (if any) received or receivable by the Company with
respect to any one share of Common Stock upon the issuance or sale of the
Convertible Security and upon the conversion or exchange or exercise of such
Convertible Security. No further adjustment of the Conversion Price shall be
made upon the actual issuance of such share of Common Stock upon conversion or
exchange or exercise of such Convertible Securities, and if any such issue or
sale of such Convertible Securities is made upon exercise of any Options for
which adjustment of the Conversion Price had been or are to be made pursuant to
other provisions of this Section 7(a), no further adjustment of the Conversion
Price shall be made by reason of such issue or sale.

                  (iii) CHANGE IN OPTION PRICE OR RATE OF CONVERSION. If the
purchase price provided for in any Options, the additional consideration, if
any, payable upon the issue, conversion, exchange or exercise of any Convertible
Securities, or the rate at which any Convertible Securities are convertible into
or exchangeable or exercisable for Common Stock changes at any time, the
Conversion Price in effect at the time of such change shall be adjusted to the
Conversion Price which would have been in effect at such time had such Options

                                      -12-

<PAGE>

or Convertible Securities provided for such changed purchase price, additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold. For purposes of this Section 7(a)(iii), if
the terms of any Option or Convertible Security that was outstanding as of the
Subscription Date are changed in the manner described in the immediately
preceding sentence, then such Option or Convertible Security and the Common
Stock deemed issuable upon exercise, conversion or exchange thereof shall be
deemed to have been issued as of the date of such change. No adjustment shall be
made if such adjustment would result in an increase of the Conversion Price then
in effect.

                  (iv) CALCULATION OF CONSIDERATION RECEIVED. In case any Option
or Convertible Security is issued in connection with the issue or sale of other
securities of the Company, together comprising one integrated transaction in
which no specific consideration is allocated to such Option or Convertible
Security by the parties thereto, the Option or Convertible Security will be
deemed to have been issued for a consideration of $.01. If any Common Stock,
Options or Convertible Securities are issued or sold or deemed to have been
issued or sold for cash, the consideration received therefor will be deemed to
be the net amount received by the Company therefor. If any Common Stock, Options
or Convertible Securities are issued or sold for a consideration other than
cash, the amount of the consideration other than cash received by the Company
will be the fair value of such consideration, except where such consideration
consists of securities, in which case the amount of consideration received by
the Company will be the Closing Sale Price of such securities on the date of
receipt. If any Common Stock, Options or Convertible Securities are issued to
the owners of the non-surviving entity in connection with any merger in which
the Company is the surviving entity, the amount of consideration therefor will
be deemed to be the fair value of such portion of the net assets and business of
the non-surviving entity as is attributable to such Common Stock, Options or
Convertible Securities, as the case may be. The fair value of any consideration
other than cash or securities will be determined jointly by the Company and the
Required Holders. If such parties are unable to reach agreement within ten (10)
days after the occurrence of an event requiring valuation (the "VALUATION
EVENT"), the fair value of such consideration will be determined within five (5)
Business Days after the tenth (10th) day following the Valuation Event by an
independent, reputable appraiser jointly selected by the Company and the
Required Holders. The determination of such appraiser shall be deemed binding
upon all parties absent manifest error and the fees and expenses of such
appraiser shall be borne by the Company.

                  (v) RECORD DATE. If the Company takes a record of the holders
of Common Stock for the purpose of entitling them (A) to receive a dividend or
other distribution payable in Common Stock, Options or in Convertible Securities
or (B) to subscribe for or purchase Common Stock, Options or Convertible
Securities, then such record date will be deemed to be the date of the issue or
sale of the Common Stock deemed to have been issued or sold upon the declaration
of such dividend or the making of such other distribution or the date of the
granting of such right of subscription or purchase, as the case may be.

                                      -13-

<PAGE>

             (b) ADJUSTMENT OF CONVERSION PRICE UPON SUBDIVISION OR COMBINATION
OF COMMON STOCK. If the Company at any time on or after the Subscription Date
subdivides (by any stock split, stock dividend, recapitalization or otherwise)
one or more classes of its outstanding shares of Common Stock into a greater
number of shares, the Conversion Price in effect immediately prior to such
subdivision will be proportionately reduced. If the Company at any time on or
after the Subscription Date combines (by combination, reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, the Conversion Price in effect immediately prior to
such combination will be proportionately increased.

             (c) OTHER EVENTS. If any event occurs of the type contemplated by
the provisions of this Section 7 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation
rights, phantom stock rights or other rights with equity features), then the
Company's Board of Directors will make an appropriate adjustment in the
Conversion Price so as to protect the rights of the Holder under this Note;
provided that no such adjustment will increase the Conversion Price as otherwise
determined pursuant to this Section 7.

         (8) COMPANY INSTALLMENT CONVERSION OR REDEMPTION.

             (a) GENERAL. On each applicable Installment Date the Company shall
pay to the Holder of this Note the Installment Amount due on such date by
converting such Installment Amount into shares of Common Stock, in accordance
with this Section 8 (a "COMPANY CONVERSION"); provided, however, that the
Company may, at its option following notice to the Holder, pay the Installment
Amount by redeeming such Installment Amount in cash (a "COMPANY REDEMPTION") or
by any combination of a Company Conversion and a Company Redemption so long as
all of the outstanding applicable Installment Amount shall be converted and/or
redeemed by the Company on the applicable Installment Date, subject to the
provisions of this Section 8; provided, further, however that if there has been
an Equity Conditions Failure, then the applicable Installment Amount shall be
redeemed in its entirety by the Company pursuant to a Company Redemption.
Notwithstanding the foregoing, the Company may not effect a Company Conversion
of any Installment Amount under this Section in excess of the Holder Pro Rata
Amount of the applicable Volume Limitation. On or prior to the date which is the
sixth (6th) Trading Day prior to each Installment Date (each, an "INSTALLMENT
NOTICE DUE DATE"), the Company shall deliver written notice (each, a "COMPANY
INSTALLMENT NOTICE" and the date all of the holders receive such notice is
referred to as to the "COMPANY INSTALLMENT NOTICE DATE"), to each holder of
Notes which Company Installment Notice shall (i) either (A) confirm that the
applicable Installment Amount of such holder's Note shall be converted in whole
pursuant to a Company Conversion (such amount to be converted, the "COMPANY
CONVERSION AMOUNT") or (B) (1) state that the Company elects to redeem, or is
required to redeem in accordance with the provisions of the Notes, in whole or
in part, the applicable Installment Amount pursuant to a Company Redemption and
(2) specify the portion (including Interest and Late Charges, if any, on such
amount and Interest) which the Company elects or is required to redeem pursuant
to a Company Redemption (such amount to be redeemed, the "COMPANY REDEMPTION
AMOUNT") and the portion (including Interest and Late Charges, if any, on such
amount and Interest), if any, that the Company elects to convert pursuant to a
Company Conversion (such amount also, a "COMPANY CONVERSION AMOUNT") which
amounts when added together, must equal the applicable Installment Amount and
(ii) if the Installment Amount is to be paid, in whole or in part, pursuant to a
Company Conversion, certify that the Equity Conditions have been satisfied as of
the date of the Company Installment Notice. Each Company Installment Notice

                                      -14-

<PAGE>

shall be irrevocable. If the Company does not timely deliver a Company
Installment Notice in accordance with this Section 8, then the Company shall be
deemed to have delivered an irrevocable Company Installment Notice confirming a
Company Conversion and shall be deemed to have certified that the Equity
Conditions in connection with any such conversion have been satisfied. Except as
expressly provided in this Section 8(a), the Company shall convert and/or redeem
the applicable Installment Amount of this Note pursuant to this Section 8 and
the corresponding Installment Amounts of the Other Notes pursuant to the
corresponding provisions of the Other Notes in the same ratio of the Installment
Amount being converted and/or redeemed hereunder. The Company Conversion Amount
(whether set forth in the Company Installment Notice or by operation of this
Section 8) shall be converted in accordance with Section 8(b) and the Company
Redemption Amount shall be redeemed in accordance with Section 8(c).

             (b) MECHANICS OF COMPANY CONVERSION. (i) If the Company delivers a
Company Installment Notice and confirms, or is deemed to have confirmed, in
whole or in part, a Company Conversion in accordance with Section 8(a), then on
the Trading Day prior to the Installment Date the Company shall, or shall direct
the Transfer Agent to, deliver to the Holder's account with DTC, or issue to the
Holder a certificate for, a number of shares of Common Stock equal to the
quotient of (A) such Company Conversion Amount divided by (B) the Initial
Company Conversion Price (the "PRE-INSTALLMENT CONVERSION SHARES"). On the
Trading Day immediately after the end of the Company Conversion Measuring Period
(the "INSTALLMENT SETTLEMENT DATE"), the Company shall, or shall direct the
Transfer Agent to, deliver to the Holder's account with DTC, or issue to the
Holder a certificate for, a number of additional shares of Common Stock, if any,
equal to the Installment Balance Conversion Shares. If an Event of Default
occurs during any applicable Company Conversion Measuring Period and the Holder
elects an Event of Default Redemption in accordance with Section 4(b), then, at
the Holder's option, either (1) the Holder, upon receipt of the Event of Default
Redemption Price (which Redemption Price includes redemption of any portion of a
Company Conversion Amount represented by Pre-Installment Conversion Shares that
the Holder shall return to the Company), shall return any Pre-Installment
Conversion Shares delivered in connection with the applicable Installment Date,
which the Holder has not otherwise sold, transferred or disposed of, to the
Company or (2) the Conversion Amount used to calculate the Event of Default
Redemption Price shall be reduced by the product of (x) the Company Conversion
Amount applicable to such Installment Date multiplied by (y) the Conversion
Share Ratio.

                   (ii) If there is an Equity Conditions Failure or the Volume
Limitation is exceeded at any time prior to the Installment Date or the
Installment Settlement Date, as applicable, then at the option of the Holder
designated in writing to the Company, the Holder may require the Company to do
either one or both of the following: (A) the Company shall redeem all or any
part designated by the Holder of the unconverted Company Conversion Amount (such
designated amount is referred to as the "FIRST REDEMPTION AMOUNT") on such
Installment Date or Installment Settlement Date, as applicable, and the Company
shall pay to the Holder on such Installment Date, by wire transfer of
immediately available funds, an amount in cash equal to 125% of such First
Redemption Amount, and/or (B) the Company Conversion shall be null and void with
respect to all or any part designated by the Holder of the unconverted Company
Conversion Amount and the Holder shall be entitled to all the rights of a holder
of this Note with respect to such amount of the Company Conversion Amount; as if
such amount had never been converted; provided, however, that the Conversion
Price for such unconverted Company Conversion Amount shall thereafter be
adjusted to equal the lesser of (1) the Company Conversion Price as in effect on
the date on which the Holder voided the Company Conversion and (2) the Company

                                      -15-

<PAGE>

Conversion Price as in effect on the date on which the Holder delivers a
Conversion Notice relating thereto. In the event the Holder elects to require
payment of the First Redemption Amount upon an Equity Conditions Failure
following the Installment Date, at the Holder's option, either (x) the Holder
shall, upon receipt of a First Redemption Amount (which amount includes
redemption of any portion of a Company Conversion Amount represented by
Pre-Installment Conversion Shares that the Holder shall return to the Company),
return any Pre-Installment Conversion Shares delivered in connection with the
applicable Installment Date, which the Holder has not otherwise sold,
transferred or disposed of, to the Company or (y) any related First Redemption
Amount shall be reduced by the product of (I) the Company Conversion Amount
applicable to such Installment Date multiplied by (II) the Conversion Share
Ratio. If the Company fails to redeem any First Redemption Amount on or before
the applicable Installment Date or Installment Settlement Date, as applicable,
by payment of such amount on the applicable Installment Date or Installment
Settlement Date, as applicable, then the Holder shall have the rights set forth
in Section 14(a) as if the Company failed to pay the applicable Company
Redemption Price and all other rights under this Note (including, without
limitation, such failure constituting an Event of Default described in Section
4(a)(xi)). Notwithstanding anything to the contrary in this Section 8(b), but
subject to 3(d), until the Company delivers Common Stock representing the
Company Conversion Amount to the Holder, the Company Conversion Amount may be
converted by the Holder into Common Stock pursuant to Section 3. In the event
that the Holder elects to convert the Company Conversion Amount prior to the
applicable Installment Date as set forth in the immediately preceding sentence,
the Company Conversion Amount so converted shall be deducted from the
Installment Amounts relating to the applicable Installment Dates as set forth in
the applicable Conversion Notice.

             (c) MECHANICS OF COMPANY REDEMPTION. If the Company elects a
Company Redemption in accordance with Section 8(a), then the Company Redemption
Amount which is to be paid to the Holder on the applicable Installment Date
shall be redeemed by the Company, and the Company shall pay to the Holder on
such Installment Date, by wire transfer of immediately available funds, an
amount in cash (the "COMPANY INSTALLMENT REDEMPTION PRICE") equal to 100% of the
Company Redemption Amount. If the Company fails to redeem the Company Redemption
Amount on the applicable Installment Date by payment of the Company Installment
Redemption Price on such date, then at the option of the Holder designated in
writing to the Company (and any such designation shall be deemed, a "CONVERSION
NOTICE" pursuant to Section 3(c) for purposes of this Note), the Holder may
require the Company to convert all or any part of the Company Redemption Amount
at 75% of the Company Conversion Price. Conversions required by this Section
8(c) shall be made in accordance with the provisions of Section 3(c).
Notwithstanding anything to the contrary in this Section 8(c), but subject to
Section 3(d), until the Company Installment Redemption Price (together with any
interest and Late Charges thereon) is paid in full, the Company Redemption
Amount (together with any Interest thereon) may be converted, in whole or in
part, by the Holder into Common Stock pursuant to Section 3. In the event the
Holder elects to convert all or any portion of the Company Redemption Amount
prior to the applicable Installment Date as set forth in the immediately
preceding sentence, the Company Redemption Amount so converted shall be deducted
from the Installment Amounts relating to the applicable Installment Dates as set
forth in the applicable Conversion Notice.

                                      -16-

<PAGE>

             (d) DEFERRED INSTALLMENT AMOUNT. Notwithstanding any provision of
this Section 8 to the contrary, the Holder may, at its option and in its sole
discretion, deliver a notice to the Company at least two (2) Business Days prior
to any Installment Notice Due Date electing to have the payment of all or any
portion of an Installment Amount payable on the next Installment Date deferred
up to a date that is two (2) years from the originally scheduled Installment
Date. Any notice delivered by the Holder pursuant to this Section 8(d) shall set
forth (i) the amount of the applicable Installment Amount being deferred and
(ii) the date that such amount shall now be payable. Any amount deferred
pursuant to this Section 8(d) shall continue to accrue Interest through the
designated payment date and shall be paid on such date in cash.

         (9) COMPANY'S RIGHT OF MANDATORY CONVERSION.

             (a) MANDATORY CONVERSION. If at any time from and after the
Effective Date (the "MANDATORY CONVERSION ELIGIBILITY DATE"), (i) the arithmetic
average of the Weighted Average Price of the Common Stock for any five (5)
consecutive Trading Days following the Mandatory Conversion Eligibility Date
(the "MANDATORY CONVERSION MEASURING PERIOD") equals or exceeds either (A) 150%
(the "FIRST CONVERSION THRESHOLD") or (B) 175% (the "SECOND CONVERSION
THRESHOLD") of the Conversion Price on the Closing Date (subject to appropriate
adjustments for stock splits, stock dividends, stock combinations and other
similar transactions after the Subscription Date) and (ii) there is not then an
Equity Conditions Failure, the Company shall have the right to require the
Holder to convert (1) if the First Conversion Threshold has been met, up to the
First Conversion Threshold Amount or (2) if the Second Conversion Threshold has
been met, all, but not less than all, of the Conversion Amount then remaining
under this Note, in each case as designated in the Mandatory Conversion Notice
(as defined below) into fully paid, validly issued and nonassessable shares of
Common Stock in accordance with Section 3(c) hereof at the Conversion Price as
of the Mandatory Conversion Date (as defined below) (a "MANDATORY CONVERSION").
The Company may exercise its right to require conversion under this Section 9(a)
by delivering within not more than two (2) Trading Days following the end of
such Mandatory Conversion Measuring Period a written notice thereof by facsimile
and overnight courier to all, but not less than all, of the holders of Notes and
the Transfer Agent (the "MANDATORY CONVERSION NOTICE" and the date all of the
holders received such notice by facsimile is referred to as the "MANDATORY
CONVERSION NOTICE Date"). The Mandatory Conversion Notice shall be irrevocable.
The Mandatory Conversion Notice shall state (u) the Trading Day selected for the
Mandatory Conversion in accordance with Section 9(a), which Trading Day shall be
no later than ten (10) Business Days following the Mandatory Conversion Notice
Date (the "MANDATORY CONVERSION DATE"), (v) the aggregate Conversion Amount,
including any applicable First Conversion Threshold Amount, of the Notes subject
to Mandatory Conversion from the Holder and all of the holders of the Notes
pursuant to this Section 9 (and analogous provisions under the Other Notes), (w)
the number of shares of Common Stock to be issued to such Holder on the
Mandatory Conversion Date, (x) that upon consummation of the Mandatory
Conversion the Series M Warrants shall become exercisable in accordance with the
terms thereof, (y) the number of shares of Common Stock into which the Series M
Warrants shall become exercisable and (z) that there has been no Equity
Conditions Failure; provided, however, that the Company may not effect a
Mandatory Conversion under this Section in excess of the Holder Pro Rata Amount
of the applicable Volume Limitation. Notwithstanding the foregoing, the Company
may effect only one (1) Mandatory Conversion with respect to the First
Conversion Threshold Amount during any twenty (20) consecutive Trading Days.

                                      -17-

<PAGE>

             (b) PRO RATA CONVERSION REQUIREMENT. If the Company elects to cause
a conversion of any Conversion Amount of this Note pursuant to Section 9(a),
then it must simultaneously take the same action in the same proportion with
respect to the Other Notes. If the Company elects a Mandatory Conversion of this
Note pursuant to Section 9(a) (or similar provisions under the Other Notes) with
respect to less than all of the Conversion Amounts of the Notes then
outstanding, then the Company shall require conversion of a Conversion Amount
from each of the holders of the Notes equal to the product of (i) the aggregate
Conversion Amount of Notes which the Company has elected to cause to be
converted pursuant to Section 9(a), multiplied by (ii) the fraction, the
numerator of which is the sum of the aggregate Original Principal Amount of the
Notes purchased by such holder of outstanding Notes and the denominator of which
is the sum of the aggregate Original Principal Amount of the Notes purchased by
all holders holding outstanding Notes (such fraction with respect to each holder
is referred to as its "CONVERSION ALLOCATION Percentage," and such amount with
respect to each holder is referred to as its "PRO RATA CONVERSION AMOUNT");
provided, however, that in the event that any holder's Pro Rata Conversion
Amount exceeds the outstanding Principal amount of such holder's Note, then such
excess Pro Rata Conversion Amount shall be allocated amongst the remaining
holders of Notes in accordance with the foregoing formula. In the event that the
initial holder of any Notes shall sell or otherwise transfer any of such
holder's Notes, the transferee shall be allocated a pro rata portion of such
holder's Conversion Allocation Percentage and the Pro Rata Conversion Amount.

         (10) HOLDER'S RIGHT OF OPTIONAL CONVERSION/REDEMPTION. At any time and
from time to time after November 30, 2006, the Holder shall have the right, in
its sole discretion, to require that the Company, provided there has been no
Equity Conditions Failure convert, or, at the Company's election, redeem a
Principal amount of this Note in an amount up to the Available
Conversion/Redemption Amount plus accrued and unpaid Late Charges with respect
to such Principal and Interest (the "CONVERSION/REDEMPTION AMOUNT") by
delivering written notice thereof (a "HOLDER OPTIONAL CONVERSION/REDEMPTION
NOTICE" and the date the Holder delivers such notice, the "HOLDER OPTIONAL
CONVERSION/REDEMPTION NOTICE DATE"). Within one (1) Business Day of the Holder
Optional Conversion/Redemption Notice Date, the Company shall deliver to the
Holder a written notice (a "COMPANY CONVERSION/REDEMPTION NOTICE" and the date
the Holder receives such written notice, the "COMPANY CONVERSION/REDEMPTION
NOTICE DATE") which notice shall (i) either (A) confirm that the
Conversion/Redemption Amount shall be converted (an "OPTIONAL CONVERSION") in
full (the "OPTIONAL CONVERSION AMOUNT") or (B)(1) state that the Company elects
to redeem (an "OPTIONAL Redemption"), in whole or in part, the
Conversion/Redemption Amount and (2) specify the portion which the Company
elects to redeem pursuant to an Optional Redemption (such amount to be redeemed,
the "OPTIONAL REDEMPTION AMOUNT") and the portion, if any, that the Company
elects to convert pursuant to an Optional Conversion (such amount also, an
"OPTIONAL CONVERSION AMOUNT") and (ii) if the Conversion/Redemption Amount is to
be paid, in whole or in part, pursuant to an Optional Conversion Amount, certify
that there has been no Equity Conditions Failure. Each Company
Conversion/Redemption Notice shall be irrevocable. The Company shall redeem and
convert any Optional Redemption Amounts and Optional Conversion Amounts within

                                      -18-

<PAGE>

five (5) Trading Days of the Company Conversion/Redemption Notice Date (the
"OPTIONAL CONVERSION/REDEMPTION DATE"). The portion of this Note subject to
redemption pursuant to this Section 10 shall be redeemed by the Company in cash
at a price equal to the Optional Redemption Amount (the "HOLDER OPTIONAL
REDEMPTION PRICE"). Optional Conversions made pursuant to this Section 10 shall
be made in accordance with Section 8(b) and references in Section 8(b) to (u)
the Installment Amount shall be deemed to refer to the Conversion/Redemption
Amount, (v) the Company Conversion shall be deemed to refer to the Optional
Conversion, (w) the Company Conversion Amount shall be deemed to refer to the
Optional Conversion Amount (plus accrued and unpaid Interest thereon), (x) the
Installment Date shall be deemed to refer to the Optional Conversion/Redemption
Date, (y) the Company Conversion Price shall be deemed to refer to the Optional
Conversion Price, and (z) the Company Conversion Measuring Period shall be
deemed to refer to the Optional Conversion Measuring Period. Optional
Redemptions made pursuant to this Section 10 shall be made in accordance with
Section 14.

         (11) [Intentionally Omitted].

         (12) NONCIRCUMVENTION. The Company hereby covenants and agrees that the
Company will not, by amendment of its Articles of Incorporation, Bylaws or
through any reorganization, transfer of assets, consolidation, merger, scheme of
arrangement, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
of this Note, and will at all times in good faith carry out all of the
provisions of this Note and take all action as may be required to protect the
rights of the Holder of this Note.

         (13) RESERVATION OF AUTHORIZED SHARES.

             (a) RESERVATION. Commencing on the Issuance Date and until the
Stockholder Approval Date, the Company shall reserve in respect of the Notes and
Warrants not less than 34,078,554 shares of Common Stock. Immediately on and
after the Stockholder Approval Date, the Company shall reserve out of its
authorized and unissued Common Stock a number of shares of Common Stock for each
of the Notes equal to 130% of the Conversion Rate with respect to the Conversion
Amount of each such Note as of the Issuance Date and, for so long thereafter as
any of the Notes are outstanding, the Company shall take all action necessary to
reserve and keep available out of its authorized and unissued Common Stock,
solely for the purpose of effecting the conversion of the Notes, 130% of the
number of shares of Common Stock as shall from time to time be necessary to
effect the conversion of all of the Notes then outstanding; provided that at no
time shall the number of shares of Common Stock so reserved be less than the
number of shares required to be reserved by the previous sentence (without
regard to any limitations on conversions) (such applicable amount, the "REQUIRED
RESERVE AMOUNT"). The initial number of shares of Common Stock reserved for
conversions of the Notes and each increase in the number of shares so reserved
shall be allocated pro rata among the holders of the Notes based on the
principal amount of the Notes held by each holder at the Closing (as defined in
the Securities Purchase Agreement) or increase in the number of reserved shares,
as the case may be (the "AUTHORIZED SHARE ALLOCATION"). In the event that a
holder shall sell or otherwise transfer any of such holder's Notes, each
transferee shall be allocated a pro rata portion of such holder's Authorized
Share Allocation. Any shares of Common Stock reserved and allocated to any
Person which ceases to hold any Notes shall be allocated to the remaining
holders of Notes, pro rata based on the principal amount of the Notes then held
by such holders.

                                      -19-

<PAGE>

             (b) INSUFFICIENT AUTHORIZED SHARES. If at any time while any of the
Notes remain outstanding the Company does not have a sufficient number of
authorized and unreserved shares of Common Stock to satisfy its obligation to
reserve for issuance upon conversion of the Notes at least a number of shares of
Common Stock equal to the Required Reserve Amount (an "AUTHORIZED SHARE
FAILURE"), then the Company shall immediately take all action necessary to
increase the Company's authorized shares of Common Stock to an amount sufficient
to allow the Company to reserve the Required Reserve Amount for the Notes then
outstanding. Without limiting the generality of the foregoing sentence, as soon
as practicable after the date of the occurrence of an Authorized Share Failure,
but in no event later than seventy-five (75) days after the occurrence of such
Authorized Share Failure, the Company shall hold a meeting of its stockholders
for the approval of an increase in the number of authorized shares of Common
Stock. In connection with such meeting, the Company shall provide each
stockholder with a proxy statement and shall use its best efforts to solicit its
stockholders' approval of such increase in authorized shares of Common Stock and
to cause its board of directors to recommend to the stockholders that they
approve such proposal.

         (14) HOLDER'S REDEMPTIONS.

             (a) MECHANICS. The Company shall deliver the applicable Event of
Default Redemption Price to the Holder within five (5) Business Days after the
Company's receipt of the Holder's Event of Default Redemption Notice. If the
Holder has submitted a Change of Control Redemption Notice in accordance with
Section 5(b), the Company shall deliver the applicable Change of Control
Redemption Price to the Holder (i) concurrently with the consummation of such
Change of Control if such notice is received prior to the consummation of such
Change of Control and (ii) within five (5) Business Days after the Company's
receipt of such notice otherwise. The Company shall deliver the applicable
Company Installment Redemption Price to the Holder on the applicable Installment
Date. The Company shall deliver the applicable Holder Optional Redemption Price
on the applicable Optional Redemption Date. In the event of a redemption of less
than all of the Conversion Amount of this Note, the Company shall promptly cause
to be issued and delivered to the Holder a new Note (in accordance with Section
20(d)) representing the outstanding Principal which has not been redeemed. In
the event that the Company does not pay the applicable Redemption Price to the
Holder within the time period required, at any time thereafter and until the
Company pays such unpaid Redemption Price in full, the Holder shall have the
option, in lieu of redemption, to require the Company to promptly return to the
Holder all or any portion of this Note representing the Conversion Amount that
was submitted for redemption and for which the applicable Redemption Price
(together with any Late Charges thereon) has not been paid. Upon the Company's
receipt of such notice, (x) the applicable Redemption Notice shall be null and
void with respect to such Conversion Amount, (y) the Company shall immediately
return this Note, or issue a new Note (in accordance with Section 20(d)) to the
Holder representing the sum of such Conversion Amount to be redeemed together
with accrued and unpaid Interest with respect to such Conversion Amount and
accrued and unpaid Late Charges with respect to such Conversion Amount and
Interest and (z) the Conversion Price of this Note or such new Notes shall be
adjusted to the lesser of (A) the Conversion Price as in effect on the date on
which the applicable Redemption Notice is voided and (B) the lowest Closing Bid
Price of the Common Stock during the period beginning on and including the date
on which the applicable Redemption Notice is delivered to the Company and ending
on and including the date on which the applicable Redemption Notice is voided.
The Holder's delivery of a notice voiding a Redemption Notice and exercise of
its rights following such notice shall not affect the Company's obligations to
make any payments of Late Charges which have accrued prior to the date of such
notice with respect to the Conversion Amount subject to such notice.

                                      -20-

<PAGE>

             (b) REDEMPTION BY OTHER HOLDERS. Upon the Company's receipt of
notice from any of the holders of the Other Notes for redemption or repayment as
a result of an event or occurrence substantially similar to the events or
occurrences described in Section 4(b), Section 5(b) or Section 10 (each, an
"OTHER REDEMPTION NOTICE"), the Company shall immediately, but no later than two
(2) Business Days of its receipt thereof, forward to the Holder by facsimile a
copy of such notice. If the Company receives a Redemption Notice and one or more
Other Redemption Notices, during the seven (7) Business Day period beginning on
and including the date which is three (3) Business Days prior to the Company's
receipt of the Holder's Redemption Notice and ending on and including the date
which is three (3) Business Days after the Company's receipt of the Holder's
Redemption Notice and the Company is unable to redeem all principal, interest
and other amounts designated in such Redemption Notice and such Other Redemption
Notices received during such seven (7) Business Day period, then the Company
shall redeem a pro rata amount from each holder of the Notes (including the
Holder) based on the principal amount of the Notes submitted for redemption
pursuant to such Redemption Notice and such Other Redemption Notices received by
the Company during such seven (7) Business Day period.

         (15) VOTING RIGHTS. The Holder shall have no voting rights as the
holder of this Note, except as required by law, including, but not limited to,
the Colorado Corporations and Associations Act, and as expressly provided in
this Note.

         (16) COVENANTS.

             (a) RANK. All payments due under this Note (a) shall rank PARI
PASSU with all Other Notes and (b) shall be senior to all other Indebtedness of
the Company and its Subsidiaries other than Permitted Senior Indebtedness.

             (b) INCURRENCE OF INDEBTEDNESS. So long as this Note is
outstanding, the Company shall not, and the Company shall not permit any of its
Subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to
exist any Indebtedness, other than the Indebtedness evidenced by this Note and
the Other Notes and other Permitted Indebtedness.

             (c) EXISTENCE OF LIENS. So long as this Note is outstanding, the
Company shall not, and the Company shall not permit any of its Subsidiaries to,
directly or indirectly, allow or suffer to exist any mortgage, lien, pledge,
charge, security interest or other encumbrance upon or in any property or assets
(including accounts and contract rights) owned by the Company or any of its
Subsidiaries (collectively, "LIENS") other than Permitted Liens.

<PAGE>

             (d) RESTRICTED PAYMENTS. The Company shall not, and the Company
shall not permit any of its Subsidiaries to, directly or indirectly, redeem,
defease, repurchase, repay or make any payments in respect of, by the payment of
cash or cash equivalents (in whole or in part, whether by way of open market
purchases, tender offers, private transactions or otherwise), all or any portion
of any Permitted Indebtedness, whether by way of payment in respect of principal
of (or premium, if any) or interest on, such Indebtedness if at the time such
payment is due or is otherwise made or, after giving effect to such payment, an
event constituting, or that with the passage of time and without being cured
would constitute, an Event of Default has occurred and is continuing.

             (e) RESTRICTION ON REDEMPTION AND CASH DIVIDENDS. Until all of the
Notes have been converted, redeemed or otherwise satisfied in accordance with
their terms, the Company shall not, directly or indirectly, redeem, repurchase
or declare or pay any cash dividend or distribution on its capital stock without
the prior express written consent of the Required Holders.

         (17) PARTICIPATION. The Holder, as the holder of this Note, shall be
entitled to receive such dividends paid and distributions made to the holders of
Common Stock to the same extent as if the Holder had converted this Note into
Common Stock (without regard to any limitations on conversion herein or
elsewhere) and had held such shares of Common Stock on the record date for such
dividends and distributions. Payments under the preceding sentence shall be made
concurrently with the dividend or distribution to the holders of Common Stock.

         (18) VOTE TO ISSUE, OR CHANGE THE TERMS OF, NOTES. The affirmative vote
at a meeting duly called for such purpose or the written consent without a
meeting of the Required Holders shall be required for any change or amendment to
this Note or the Other Notes.

         (19) TRANSFER. This Note and any shares of Common Stock issued upon
conversion of this Note may be offered, sold, assigned or transferred by the
Holder without the consent of the Company, subject only to the provisions of
Section 2(f) of the Securities Purchase Agreement.

         (20) REISSUANCE OF THIS NOTE.

             (a) TRANSFER. If this Note is to be transferred, the Holder shall
surrender this Note to the Company, whereupon the Company will forthwith issue
and deliver upon the order of the Holder a new Note (in accordance with Section
20(d)), registered as the Holder may request, representing the outstanding
Principal being transferred by the Holder and, if less then the entire
outstanding Principal is being transferred, a new Note (in accordance with
Section 20(d)) to the Holder representing the outstanding Principal not being
transferred. The Holder and any assignee, by acceptance of this Note,
acknowledge and agree that, by reason of the provisions of Section 3(c)(iii)
following conversion or redemption of any portion of this Note, the outstanding
Principal represented by this Note may be less than the Principal stated on the
face of this Note.

                                      -22-

<PAGE>

             (b) LOST, STOLEN OR MUTILATED NOTE. Upon receipt by the Company of
evidence reasonably satisfactory to the Company of the loss, theft, destruction
or mutilation of this Note, and, in the case of loss, theft or destruction, of
any indemnification undertaking by the Holder to the Company in customary form
and, in the case of mutilation, upon surrender and cancellation of this Note,
the Company shall execute and deliver to the Holder a new Note (in accordance
with Section 20(d)) representing the outstanding Principal.

             (c) NOTE EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This Note is
exchangeable, upon the surrender hereof by the Holder at the principal office of
the Company, for a new Note or Notes (in accordance with Section 20(d) and in
principal amounts of at least $100,000) representing in the aggregate the
outstanding Principal of this Note, and each such new Note will represent such
portion of such outstanding Principal as is designated by the Holder at the time
of such surrender.

             (d) ISSUANCE OF NEW NOTES. Whenever the Company is required to
issue a new Note pursuant to the terms of this Note, such new Note (i) shall be
of like tenor with this Note, (ii) shall represent, as indicated on the face of
such new Note, the Principal remaining outstanding (or in the case of a new Note
being issued pursuant to Section 20(a) or Section 20(c), the Principal
designated by the Holder which, when added to the principal represented by the
other new Notes issued in connection with such issuance, does not exceed the
Principal remaining outstanding under this Note immediately prior to such
issuance of new Notes), (iii) shall have an issuance date, as indicated on the
face of such new Note, which is the same as the Issuance Date of this Note, (iv)
shall have the same rights and conditions as this Note, and (v) shall represent
accrued and unpaid Interest and Late Charges, if any, on the Principal and
Interest of this Note, from the Issuance Date.

         (21) REMEDIES, CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND
INJUNCTIVE RELIEF. The remedies provided in this Note shall be cumulative and in
addition to all other remedies available under this Note and any of the other
Transaction Documents at law or in equity (including a decree of specific
performance and/or other injunctive relief), and nothing herein shall limit the
Holder's right to pursue actual and consequential damages for any failure by the
Company to comply with the terms of this Note. Amounts set forth or provided for
herein with respect to payments, conversion and the like (and the computation
thereof) shall be the amounts to be received by the Holder and shall not, except
as expressly provided herein, be subject to any other obligation of the Company
(or the performance thereof). The Company acknowledges that a breach by it of
its obligations hereunder will cause irreparable harm to the Holder and that the
remedy at law for any such breach may be inadequate. The Company therefore
agrees that, in the event of any such breach or threatened breach, the Holder
shall be entitled, in addition to all other available remedies, to an injunction
restraining any breach, without the necessity of showing economic loss and
without any bond or other security being required.

         (22) PAYMENT OF COLLECTION, ENFORCEMENT AND OTHER COSTS. If (a) this
Note is placed in the hands of an attorney for collection or enforcement or is
collected or enforced through any legal proceeding or the Holder otherwise takes
action to collect amounts due under this Note or to enforce the provisions of
this Note or (b) there occurs any bankruptcy, reorganization, receivership of
the Company or other proceedings affecting Company creditors' rights and
involving a claim under this Note, then the Company shall pay the costs incurred
by the Holder for such collection, enforcement or action or in connection with
such bankruptcy, reorganization, receivership or other proceeding, including,
but not limited to, attorneys' fees and disbursements.

         (23) CONSTRUCTION; HEADINGS. This Note shall be deemed to be jointly
drafted by the Company and all the Purchasers and shall not be construed against
any person as the drafter hereof. The headings of this Note are for convenience
of reference and shall not form part of, or affect the interpretation of, this
Note.

         (24) FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the part
of the Holder in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

         (25) DISPUTE RESOLUTION. In the case of a dispute as to the
determination of the Closing Bid Price, the Closing Sale Price or the Weighted
Average Price or the arithmetic calculation of the Conversion Rate, Conversion
Price or any Redemption Price, the Company shall submit the disputed
determinations or arithmetic calculations via facsimile within three (3)
Business Days of receipt, or deemed receipt, of the Conversion Notice or
Redemption Notice or other event giving rise to such dispute, as the case may
be, to the Holder. If the Holder and the Company are unable to agree upon such
determination or calculation within three (3) Business Days of such disputed
determination or arithmetic calculation being submitted to the Holder, then the
Company shall, within three (3) Business Days submit via facsimile (a) the
disputed determination of the Closing Bid Price, the Closing Sale Price or the
Weighted Average Price to an independent, reputable investment bank selected by
the Company and approved by the Holder or (b) the disputed arithmetic
calculation of the Conversion Rate, Conversion Price or any Redemption Price to
the Company's independent, outside accountant. The Company, at the Company's
expense, shall cause the investment bank or the accountant, as the case may be,
to perform the determinations or calculations and notify the Company and the
Holder of the results no later than ten (10) Business Days from the time it
receives the disputed determinations or calculations. Such investment bank's or
accountant's determination or calculation, as the case may be, shall be binding
upon all parties absent demonstrable error.

         (26) NOTICES; PAYMENTS.

             (a) NOTICES. Whenever notice is required to be given under this
Note, unless otherwise provided herein, such notice shall be given in accordance
with Section 10(f) of the Securities Purchase Agreement. The Company shall
provide the Holder with prompt written notice of all actions taken pursuant to
this Note, including in reasonable detail a description of such action and the
reason therefore. Without limiting the generality of the foregoing, the Company
will give written notice to the Holder (i) immediately upon any adjustment of
the Conversion Price, setting forth in reasonable detail, and certifying, the
calculation of such adjustment and (ii) at least twenty (20) days prior to the
date on which the Company closes its books or takes a record (A) with respect to
any dividend or distribution upon the Common Stock, (B) with respect to any pro
rata subscription offer to holders of Common Stock or (C) for determining rights
to vote with respect to any Fundamental Transaction, dissolution or liquidation,
provided in each case that such information shall be made known to the public
prior to or in conjunction with such notice being provided to the Holder.

             (b) PAYMENTS. Whenever any payment of cash is to be made by the
Company to any Person pursuant to this Note, such payment shall be made in
lawful money of the United States of America by a check drawn on the account of
the Company and sent via overnight courier service to such Person at such
address as previously provided to the Company in writing (which address, in the
case of each of the Purchasers, shall initially be as set forth on the Schedule
of Buyers attached to the Securities Purchase Agreement); provided that the
Holder may elect to receive a payment of cash via wire transfer of immediately
available funds by providing the Company with prior written notice setting out
such request and the Holder's wire transfer instructions. Whenever any amount
expressed to be due by the terms of this Note is due on any day which is not a
Business Day, the same shall instead be due on the next succeeding day which is
a Business Day and, in the case of any Interest Date which is not the date on
which this Note is paid in full, the extension of the due date thereof shall not
be taken into account for purposes of determining the amount of Interest due on
such date. Any amount of Principal or other amounts due under the Transaction
Documents, other than Interest, which is not paid when due shall result in a
late charge being incurred and payable by the Company in an amount equal to
interest on such amount at the rate of eighteen percent (18%) per annum from the
date such amount was due until the same is paid in full ("LATE CHARGE").

         (27) CANCELLATION. After all Principal, accrued Interest and other
amounts at any time owed on this Note have been paid in full, this Note shall
automatically be deemed canceled, shall be surrendered to the Company for
cancellation and shall not be reissued.

         (28) WAIVER OF NOTICE. To the extent permitted by law, the Company
hereby waives demand, notice, protest and all other demands and notices in
connection with the delivery, acceptance, performance, default or enforcement of
this Note and the Securities Purchase Agreement.

         (29) GOVERNING LAW. This Note shall be construed and enforced in
accordance with, and all questions concerning the construction, validity,
interpretation and performance of this Note shall be governed by, the internal
laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other
jurisdictions) that would cause the application of the laws of any jurisdictions
other than the State of New York. The Company hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in The City of
New York, Borough of Manhattan, for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is
improper. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. In the event that any provision
of this Note is invalid or unenforceable under any applicable statute or rule of
law, then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision
of this Note. Nothing contained herein shall be deemed or operate to preclude

                                      -25-

the Holder from bringing suit or taking other legal action against the Company
in any other jurisdiction to collect on the Company's obligations to the Holder,
to realize on any collateral or any other security for such obligations, or to

or securities market on which the Common Stock is then traded; provided that
"Trading Day" shall not include any day on which the Common Stock is scheduled
to trade on such exchange or market for less than 4.5 hours or any day that the
Common Stock is suspended from trading during the final hour of trading on such
exchange or market (or if such exchange or market does not designate in advance
the closing time of trading on such exchange or market, then during the hour
ending at 4:00:00 p.m., New York Time).

             (ccc) "VOLUME LIMITATION" means 20% of the aggregate dollar trading
volume (as reported on Bloomberg) of the Common Stock on the Principal Market
over the twenty (20) consecutive Trading Day period immediately prior to the
applicable Interest Notice Date or the Installment Notice Date or the Mandatory
Conversion Notice Date, as applicable.

             (ddd) "VOTING STOCK" of a Person means capital stock of such Person
of the class or classes pursuant to which the holders thereof have the general
voting power to elect, or the general power to appoint, at least a majority of
the board of directors, managers or trustees of such Person (irrespective of
whether or not at the time capital stock of any other class or classes shall
have or might have voting power by reason of the happening of any contingency).

             (eee) "WARRANTS" has the meaning ascribed to such term in the
Securities Purchase Agreement, and shall include all warrants issued in exchange
therefor or replacement thereof.

             (fff) "WEIGHTED AVERAGE PRICE" means, for any security as of any
date, the dollar volume-weighted average price for such security on the
Principal Market during the period beginning at 9:30:01 a.m., New York Time (or
such other time as the Principal Market publicly announces is the official open
of trading), and ending at 4:00:00 p.m., New York Time (or such other time as
the Principal Market publicly announces is the official close of trading) as
reported by Bloomberg through its "Volume at Price" functions, or, if the
foregoing does not apply, the dollar volume-weighted average price of such
security in the over-the-counter market on the electronic bulletin board for
such security during the period beginning at 9:30:01 a.m., New York Time (or

                                      -35-

<PAGE>

such other time as such market publicly announces is the official open of
trading), and ending at 4:00:00 p.m., New York Time (or such other time as such
market publicly announces is the official close of trading) as reported by
Bloomberg, or, if no dollar volume-weighted average price is reported for such
security by Bloomberg for such hours, the average of the highest closing bid
price and the lowest closing ask price of any of the market makers for such
security as reported in the "pink sheets" by Pink Sheets LLC (formerly the
National Quotation Bureau, Inc.). If the Weighted Average Price cannot be
calculated for a security on a particular date on any of the foregoing bases,
the Weighted Average Price of such security on such date shall be the fair
market value as mutually determined by the Company and the Holder. If the
Company and the Holder are unable to agree upon the fair market value of such
security, then such dispute shall be resolved pursuant to Section 25. All such
determinations shall be appropriately adjusted for any stock dividend, stock
split, stock combination or other similar transaction during the applicable
calculation period.

         (31) DISCLOSURE. Upon receipt or delivery by the Company of any notice
in accordance with the terms of this Note, unless the Company has in good faith

                        WARRANT TO PURCHASE COMMON STOCK

Warrant No.: L-__
Number of Shares of Common Stock:
Date of Issuance: July 31, 2006 ("ISSUANCE DATE")

                  Raptor Networks Technology, Inc., a Colorado corporation, (the
"COMPANY"), hereby certifies that, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged,
_________________________________ the registered holder hereof or its permitted
assigns (the "HOLDER"), is entitled, subject to the terms set forth below, to
purchase from the Company, at the Exercise Price (as defined below) then in
effect, upon surrender of this Warrant to Purchase Common Stock (including any
Warrants to purchase Common Stock issued in exchange, transfer or replacement
hereof, the "WARRANT"), at any time or times on or after the date hereof, but
not after 11:59 p.m., New York Time, on the Expiration Date (as defined below),
______________ ( ) fully paid nonassessable shares of Common Stock (as defined
below) (the "WARRANT SHARES"). Except as otherwise defined herein, capitalized
terms in this Warrant shall have the meanings set forth in Section 15. This
Warrant is one of the Warrants to purchase Common Stock (the "SPA WARRANTS")
issued pursuant to Section 1 of that certain Securities Purchase Agreement,
dated as of July 30, 2006 (the "SUBSCRIPTION DATE"), by and among the Company
and the investors (the "BUYERS") referred to therein (the "SECURITIES PURCHASE
AGREEMENT").

                  1. EXERCISE OF WARRANT.

                           (a) MECHANICS OF EXERCISE. Subject to the terms and
conditions hereof (including, without limitation, the limitations set forth in
Section 1(f)), this Warrant may be exercised by the Holder on any day on or
after the date hereof in whole or in part, by (i) delivery of a written notice,

<PAGE>

in the form attached hereto as EXHIBIT A (the "EXERCISE NOTICE"), of the
Holder's election to exercise this Warrant and (ii) (A) payment to the Company
of an amount equal to the applicable Exercise Price multiplied by the number of
Warrant Shares as to which this Warrant is being exercised (the "AGGREGATE
EXERCISE PRICE") in cash or wire transfer of immediately available funds or (B)
by notifying the Company that this Warrant is being exercised pursuant to a
Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required
to deliver the original Warrant in order to effect an exercise hereunder.
Execution and delivery of the Exercise Notice with respect to less than all of
the Warrant Shares shall have the same effect as cancellation of the original
Warrant and issuance of a new Warrant evidencing the right to purchase the
remaining number of Warrant Shares. On or before the first Business Day
following the date on which the Company has received each of the Exercise Notice
and the Aggregate Exercise Price (or notice of a Cashless Exercise) (the
"EXERCISE DELIVERY DOCUMENTS"), the Company shall transmit by facsimile an
acknowledgment of confirmation of receipt of the Exercise Delivery Documents to
the Holder and the Company's transfer agent (the "TRANSFER AGENT"). On or before
the third Business Day following the date on which the Company has received all
of the Exercise Delivery Documents (the "SHARE DELIVERY DATE"), the Company
shall (X) provided that the Transfer Agent is participating in The Depository
Trust Company ("DTC") Fast Automated Securities Transfer Program, upon the
request of the Holder, credit such aggregate number of shares of Common Stock to
which the Holder is entitled pursuant to such exercise to the Holder's or its
designee's balance account with DTC through its Deposit Withdrawal Agent
Commission system, or (Y) if the Transfer Agent is not participating in the DTC
Fast Automated Securities Transfer Program, deliver to be received no later than
the Share Delivery Date, to the address as specified in the Exercise Notice, a
certificate, registered in the Company's share register in the name of the
Holder or its designee, for the number of shares of Common Stock to which the
Holder is entitled pursuant to such exercise. Upon delivery of the Exercise
Notice and Aggregate Exercise Price referred to in clause (ii)(A) above or
notification to the Company of a Cashless Exercise referred to in Section 1(d),
the Holder shall be deemed for all corporate purposes to have become the holder
of record of the Warrant Shares with respect to which this Warrant has been
exercised, irrespective of the date of delivery of the certificates evidencing
such Warrant Shares. If this Warrant is submitted in connection with any
exercise pursuant to this Section 1(a) and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of
Warrant Shares being acquired upon an exercise, then the Company shall as soon
as practicable and in no event later than five (5) Business Days after any
exercise and at its own expense, issue a new Warrant (in accordance with Section
7(d)) representing the right to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under this Warrant, less the
number of Warrant Shares with respect to which this Warrant is exercised. No
fractional shares of Common Stock are to be issued upon the exercise of this
Warrant, but rather the number of shares of Common Stock to be issued shall be
rounded up to the nearest whole number. The Company shall pay any and all taxes
which may be payable with respect to the issuance and delivery of Warrant Shares
upon exercise of this Warrant.

                           (b) EXERCISE PRICE. For purposes of this Warrant,
"EXERCISE PRICE" means $0.5054, subject to adjustment as provided herein.

<PAGE>

                           (c) COMPANY'S FAILURE TO TIMELY DELIVER SECURITIES.
If the Company shall fail for any reason or for no reason to issue to the Holder
within five (5) Trading Days of receipt of the Exercise Delivery Documents, a
certificate for the number of shares of Common Stock to which the Holder is
entitled and register such shares of Common Stock on the Company's share
register or to credit the Holder's balance account with DTC for such number of
shares of Common Stock to which the Holder is entitled upon the Holder's
exercise of this Warrant, then, in addition to all other remedies available to
the Holder, the Company shall pay in cash to the Holder on each day after such
third Business Day that the issuance of such shares of Common Stock is not
timely effected an amount equal to 1.5% of the product of (A) the sum of the
number of shares of Common Stock not issued to the Holder on a timely basis and
to which the Holder is entitled and (B) the Closing Sale Price of the shares of
Common Stock on the Trading Day immediately preceding the last possible date
which the Company could have issued such shares of Common Stock to the Holder
without violating Section 1(a). In addition, if within three (3) Trading Days
after the Company's receipt of the facsimile copy of a Exercise Notice the
Company shall fail to issue and deliver a certificate to the Holder and register
such shares of Common Stock on the Company's share register or credit the
Holder's balance account with DTC for the number of shares of Common Stock to
which the Holder is entitled upon such holder's exercise hereunder, and if on or
after such Trading Day the Holder purchases (in an open market transaction or
otherwise) shares of Common Stock to deliver in satisfaction of a sale by the
Holder of shares of Common Stock issuable upon such exercise that the Holder
anticipated receiving from the Company (a "BUY-IN"), then the Company shall,
within five (5) Business Days after the Holder's request and in the Holder's
discretion, either (i) pay cash to the Holder in an amount equal to the Holder's
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased (the "BUY-IN PRICE"), at which point the Company's
obligation to deliver such certificate (and to issue such shares of Common
Stock) or credit such Holder's balance account with DTC shall terminate, or (ii)
promptly honor its obligation to deliver to the Holder a certificate or
certificates representing such shares of Common Stock or credit such Holder's
balance account with DTC and pay cash to the Holder in an amount equal to the
excess (if any) of the Buy-In Price over the product of (A) such number of
shares of Common Stock, times (B) the Closing Bid Price on the date of exercise.

                           (d) CASHLESS EXERCISE. Notwithstanding anything
contained herein to the contrary, if a Registration Statement (as defined in the
Registration Rights Agreement) covering the Warrant Shares that are the subject
of the Exercise Notice (the "UNAVAILABLE WARRANT SHARES") is not available for
the resale of such Unavailable Warrant Shares, the Holder may, in its sole
discretion, exercise this Warrant in whole or in part and, in lieu of making the
cash payment otherwise contemplated to be made to the Company upon such exercise
in payment of the Aggregate Exercise Price, elect instead to receive upon such
exercise the "Net Number" of shares of Common Stock determined according to the
following formula (a "CASHLESS EXERCISE"):

                           Net Number = (A X B) - (A X C)
                                        -----------------
                                               B

                           For purposes of the foregoing formula:

                                      -3-

<PAGE>

                  A= the total number of shares with respect to which this
Warrant is then being exercised.

                  B= the Closing Sale Price of the shares of Common Stock (as
reported by Bloomberg) on the date immediately preceding the date of the
Exercise Notice.

                  C= the Exercise Price then in effect for the applicable
Warrant Shares at the time of such exercise.

                           (e) DISPUTES. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, the Company shall promptly issue to the Holder the number of Warrant
Shares that are not disputed and resolve such dispute in accordance with Section
12.

                           (f) Limitations on Exercises.

                                    (i) BENEFICIAL OWNERSHIP. The Company shall
                           not effect the exercise of this Warrant, and the
                           Holder shall not have the right to exercise this
                           Warrant, to the extent that after giving effect to
                           such exercise, such Person (together with such
                           Person's affiliates) would beneficially own in excess
                           of 4.99% of the shares of Common Stock outstanding
                           immediately after giving effect to such exercise. For
                           purposes of the foregoing sentence, the aggregate
                           number of shares of Common Stock beneficially owned
                           by such Person and its affiliates shall include the
                           number of shares of Common Stock issuable upon
                           exercise of this Warrant with respect to which the
                           determination of such sentence is being made, but
                           shall exclude shares of Common Stock which would be
                           issuable upon (A) exercise of the remaining,
                           unexercised portion of this Warrant beneficially
                           owned by such Person and its affiliates and (B)
                           exercise or conversion of the unexercised or
                           unconverted portion of any other securities of the
                           Company beneficially owned by such Person and its
                           affiliates (including, without limitation, any
                           convertible notes or convertible preferred stock or
                           warrants) subject to a limitation on conversion or
                           exercise analogous to the limitation contained
                           herein. Except as set forth in the preceding
                           sentence, for purposes of this paragraph, beneficial
                           ownership shall be calculated in accordance with
                           Section 13(d) of the Securities Exchange Act of 1934,
                           as amended (the "EXCHANGE ACT"). For purposes of this
                           Warrant, in determining the number of outstanding
                           shares of Common Stock, the Holder may rely on the
                           number of outstanding shares of Common Stock as
                           reflected in (1) the Company's most recent Form 10-K,
                           10-KSB, Form 10-Q, 10-QSB, Current Report on Form 8-K
                           or other public filing with the Securities and
                           Exchange Commission, as the case may be, (2) a more
                           recent public announcement by the Company or (3) any
                           other notice by the Company or the Transfer Agent

                                      -4-

<PAGE>

                           setting forth the number of shares of Common Stock
                           outstanding. For any reason at any time, upon the
                           written or oral request of the Holder, the Company
                           shall within two (2) Business Day confirm orally and
                           in writing to the Holder the number of shares of
                           Common Stock then outstanding. In any case, the
                           number of outstanding shares of Common Stock shall be
                           determined after giving effect to the conversion or
                           exercise of securities of the Company, including the
                           SPA Securities and the SPA Warrants, by the Holder
                           and its affiliates since the date as of which such
                           number of outstanding shares of Common Stock was
                           reported. By written notice to the Company, the
                           Holder may increase or decrease the Maximum
                           Percentage to any other percentage not in excess of
                           9.99% specified in such notice; provided that (i) any
                           such increase will not be effective until the
                           sixty-first (61st) day after such notice is delivered
                           to the Company, and (ii) any such increase or
                           decrease will apply only to the Holder and not to any
                           other holder of SPA Warrants.

                                    (ii) PRINCIPAL MARKET REGULATION. The
                           Company shall not be obligated to issue any shares of
                           Common Stock upon exercise of this Warrant or
                           conversion of SPA Securities and no Buyer shall be
                           entitled to receive any shares of Common Stock if the
                           issuance of such shares of Common Stock would exceed
                           that number of shares of Common Stock which the
                           Company may issue upon exercise or conversion, as
                           applicable, of the SPA Warrants and SPA Securities or
                           otherwise without breaching the Company's obligations
                           under the rules or regulations of any applicable
                           Eligible Market (the "EXCHANGE CAP"), except that
                           such limitation shall not apply in the event that the
                           Company (A) obtains the approval of its shareholders
                           as required by the applicable rules of the Eligible
                           Market for issuances of shares of Common Stock in
                           excess of such amount or (B) obtains a written
                           opinion from outside counsel to the Company that such
                           approval is not required, which opinion shall be
                           reasonably satisfactory to the Required Holders.
                           Until such approval or written opinion is obtained,
                           no Buyer shall be issued in the aggregate, upon
                           exercise or conversion, as applicable, of any SPA
                           Warrants or SPA Securities, shares of Common Stock in
                           an amount greater than the product of the Exchange
                           Cap multiplied by a fraction, the numerator of which
                           is the total number of shares of Common Stock
                           underlying the SPA Warrants issued to such Buyer
                           pursuant to the Securities Purchase Agreement on the
                           Issuance Date and the denominator of which is the
                           aggregate number of shares of Common Stock underlying
                           the SPA Warrants issued to the Buyers pursuant to the
                           Securities Purchase Agreement on the Issuance Date
                           (with respect to each Buyer, the "EXCHANGE CAP
                           ALLOCATION"). In the event that any Buyer shall sell
                           or otherwise transfer any of such Buyer's SPA
                           Warrants, the transferee shall be allocated a pro
                           rata portion of such Buyer's Exchange Cap Allocation,
                           and the restrictions of the prior sentence shall
                           apply to such transferee with respect to the portion

                                      -5-

                           of the Exchange Cap Allocation allocated to such
                           transferee. In the event that any holder of SPA
                           Warrants shall exercise all of such holder's SPA
                           Warrants into a number of shares of Common Stock
                           which, in the aggregate, is less than such holder's
                           Exchange Cap Allocation, then the difference between
                           such holder's Exchange Cap Allocation and the number
                           of shares of Common Stock actually issued to such
                           holder shall be allocated to the respective Exchange
                           Cap Allocations of the remaining holders of SPA
                           Warrants on a pro rata basis in proportion to the
                           shares of Common Stock underlying the SPA Warrants
                           then held by each such holder. In the event that the
                           Company is prohibited from issuing any Warrant Shares
                           for which an Exercise Notice has been received as a
                           result of the operation of this Section 1(f)(ii), the
                           Company shall pay cash in exchange for cancellation
                           of such Warrant Shares, at a price per Warrant Share
                           equal to the difference between the Closing Sale
                           Price and the Exercise Price as of the date of the
                           attempted exercise.

                  2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.
The Exercise Price and the number of Warrant Shares shall be adjusted from time
to time as follows:

                           (a) ADJUSTMENT UPON ISSUANCE OF SHARES OF COMMON
STOCK. If and whenever on or after the Subscription Date the Company issues or
sells, or in accordance with this Section 2 is deemed to have issued or sold,
any shares of Common Stock (including the issuance or sale of shares of Common
Stock owned or held by or for the account of the Company, but excluding shares
of Common Stock deemed to have been issued by the Company in connection with any
Excluded Securities (as defined in the SPA Securities)) for a consideration per
share (the "NEW ISSUANCE PRICE") less than the Exercise Price (the "APPLICABLE
PRICE") in effect immediately prior to such issue or sale or deemed issuance or
sale (the foregoing a "DILUTIVE ISSUANCE"), then immediately after such Dilutive
Issuance, the Exercise Price then in effect shall be reduced to an amount equal
to the New Issuance Price. Upon each such adjustment of the Exercise Price
hereunder, the number of Warrant Shares shall be adjusted to the number of
shares of Common Stock determined by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of Warrant Shares acquirable
upon exercise of this Warrant immediately prior to such adjustment and dividing
the product thereof by the Exercise Price resulting from such adjustment. For
purposes of determining the adjusted Exercise Price under this Section 2(a), the
following shall be applicable:

                                    (i) ISSUANCE OF OPTIONS. If the Company in
                           any manner grants any Options and the lowest price
                           per share for which one share of shares of Common
                           Stock is issuable upon the exercise of any such
                           Option or upon conversion, exercise or exchange of
                           any Convertible Securities issuable upon exercise of
                           any such Option is less than the Applicable Price,
                           then such share of Common Stock shall be deemed to be
                           outstanding and to have been issued and sold by the
                           Company at the time of the granting or sale of such
                           Option for such price per share. For purposes of this
                           Section 2(a)(i), the "lowest price per share for
                           which one share of shares of Common Stock is issuable
                           upon exercise of such Options or upon conversion,
                           exercise or exchange of such Convertible Securities"

                           shall be equal to the sum of the lowest amounts of
                           consideration (if any) received or receivable by the
                           Company with respect to any one share of shares of
                           Common Stock upon the granting or sale of the Option,
                           upon exercise of the Option and upon conversion,
                           exercise or exchange of any Convertible Security
                           issuable upon exercise of such Option. No further
                           adjustment of the Exercise Price or number of Warrant
                           Shares shall be made upon the actual issuance of such
                           shares of Common Stock or of such Convertible
                           Securities upon the exercise of such Options or upon
                           the actual issuance of such shares of Common Stock
                           upon conversion, exercise or exchange of such
                           Convertible Securities.

                                    (ii) ISSUANCE OF CONVERTIBLE SECURITIES. If
                           the Company in any manner issues or sells any
                           Convertible Securities and the lowest price per share
                           for which one share of shares of Common Stock is
                           issuable upon the conversion, exercise or exchange
                           thereof is less than the Applicable Price, then such
                           share of Common Stock shall be deemed to be
                           outstanding and to have been issued and sold by the
                           Company at the time of the issuance or sale of such
                           Convertible Securities for such price per share. For
                           the purposes of this Section 2(a)(ii), the "lowest
                           price per share for which one share of shares of
                           Common Stock is issuable upon the conversion,
                           exercise or exchange" shall be equal to the sum of
                           the lowest amounts of consideration (if any) received
                           or receivable by the Company with respect to one
                           share of shares of Common Stock upon the issuance or
                           sale of the Convertible Security and upon conversion,
                           exercise or exchange of such Convertible Security. No
                           further adjustment of the Exercise Price or number of
                           Warrant Shares shall be made upon the actual issuance
                           of such shares of Common Stock upon conversion,
                           exercise or exchange of such Convertible Securities,
                           and if any such issue or sale of such Convertible
                           Securities is made upon exercise of any Options for
                           which adjustment of this Warrant has been or is to be
                           made pursuant to other provisions of this Section
                           2(a), no further adjustment of the Exercise Price or
                           number of Warrant Shares shall be made by reason of
                           such issue or sale.

                                    (iii) CHANGE IN OPTION PRICE OR RATE OF
                           CONVERSION. If the purchase price provided for in any
                           Options, the additional consideration, if any,
                           payable upon the issue, conversion, exercise or
                           exchange of any Convertible Securities, or the rate
                           at which any Convertible Securities are convertible
                           into or exercisable or exchangeable for shares of
                           Common Stock increases or decreases at any time, the
                           Exercise Price and the number of Warrant Shares in
                           effect at the time of such increase or decrease shall
                           be adjusted to the Exercise Price and the number of
                           Warrant Shares which would have been in effect at
                           such time had such Options or Convertible Securities
                           provided for such increased or decreased purchase
                           price, additional consideration or increased or
                           decreased conversion rate, as the case may be, at the
                           time initially granted, issued or sold. For purposes
                           of this Section 2(a)(iii), if the terms of any Option

                                      -7-

                           or Convertible Security that were outstanding as of
                           the date of issuance of this Warrant are increased or
                           decreased in the manner described in the immediately
                           preceding sentence, then such Option or Convertible
                           Security and the shares of Common Stock deemed
                           issuable upon exercise, conversion or exchange
                           thereof shall be deemed to have been issued as of the
                           date of such increase or decrease. No adjustment
                           pursuant to this Section 2(a)(iii) shall be made if
                           such adjustment would result in an increase of the
                           Exercise Price then in effect or a decrease in the
                           number of Warrant Shares.

                                    (iv) CALCULATION OF CONSIDERATION RECEIVED.
                           In case any Option or Convertible Security is issued
                           in connection with the issue or sale of other
                           securities of the Company, together comprising one
                           integrated transaction in which no specific
                           consideration is allocated to such Option or
                           Convertible Security by the parties thereto, the
                           Option or Convertible Security will be deemed to have
                           been issued for a consideration of $0.01. If any
                           shares of Common Stock, Options or Convertible
                           Securities are issued or sold or deemed to have been
                           issued or sold for cash, the consideration received
                           therefor will be deemed to be the net amount received
                           by the Company therefor. If any shares of Common
                           Stock, Options or Convertible Securities are issued
                           or sold for a consideration other than cash, the
                           amount of such consideration received by the Company
                           will be the fair value of such consideration, except
                           where such consideration consists of publicly traded
                           securities, in which case the amount of consideration
                           received by the Company will be the Closing Sale
                           Price of such security on the date of receipt. If any
                           shares of Common Stock, Options or Convertible
                           Securities are issued to the owners of the
                           non-surviving entity in connection with any merger in
                           which the Company is the surviving entity, the amount
                           of consideration therefor will be deemed to be the
                           fair value of such portion of the net assets and
                           business of the non-surviving entity as is
                           attributable to such shares of Common Stock, Options
                           or Convertible Securities, as the case may be. The
                           fair value of any consideration other than cash or
                           publicly traded securities will be determined jointly
                           by the Company and the Required Holders. If such
                           parties are unable to reach agreement within ten (10)
                           days after the occurrence of an event requiring
                           valuation (the "VALUATION EVENT"), the fair value of
                           such consideration will be determined within five (5)
                           Business Days after the tenth day following the
                           Valuation Event by an independent, reputable
                           appraiser jointly selected by the Company and the
                           Required Holders. The determination of such appraiser
                           shall be final and binding upon all parties absent
                           manifest error and the fees and expenses of such
                           appraiser shall be borne by the Company.

                                    (v) RECORD DATE. If the Company takes a
                           record of the holders of shares of Common Stock for
                           the purpose of entitling them (A) to receive a

                                      -8-

                           dividend or other distribution payable in shares of
                           Common Stock, Options or in Convertible Securities or
                           (B) to subscribe for or purchase shares of Common
                           Stock, Options or Convertible Securities, then such
                           record date will be deemed to be the date of the
                           issue or sale of the shares of Common Stock deemed to
                           have been issued or sold upon the declaration of such
                           dividend or the making of such other distribution or
                           the date of the granting of such right of
                           subscription or purchase, as the case may be.

                           (b) ADJUSTMENT UPON SUBDIVISION OR COMBINATION OF
SHARES OF COMMON STOCK. If the Company at any time on or after the Subscription
Date subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the Exercise Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of Warrant Shares
will be proportionately increased. If the Company at any time on or after the
Subscription Date combines (by combination, reverse stock split or otherwise)
one or more classes of its outstanding shares of Common Stock into a smaller
number of shares, the Exercise Price in effect immediately prior to such
combination will be proportionately increased and the number of Warrant Shares
will be proportionately decreased. Any adjustment under this Section 2(b) shall
become effective at the close of business on the date the subdivision or
combination becomes effective.

                           (c) OTHER EVENTS. If any event occurs of the type
contemplated by the provisions of this Section 2 but not expressly provided for
by such provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Company's Board of Directors will make an appropriate adjustment in the
Exercise Price and the number of Warrant Shares so as to protect the rights of
the Holder; provided that no such adjustment pursuant to this Section 2(c) will
increase the Exercise Price or decrease the number of Warrant Shares as
otherwise determined pursuant to this Section 2.

                           (d) ADJUSTMENT UPON EVENT OF DEFAULT. Upon the
occurrence of an Event of Default (as defined in the SPA Securities), the
Exercise Price shall be reset to the lower of (A) the Exercise Price then in
effect and (B) the Average Market Price of the Common Stock; provided, however,
that no such adjustment pursuant to this Section 2(d) will increase the Exercise
Price. Upon each such adjustment of the Exercise Price hereunder, the number of
Warrant Shares shall be adjusted to the number of shares of Common Stock
determined by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Shares acquirable upon exercise of this
Warrant immediately prior to such adjustment and dividing the product thereof by
the Exercise Price resulting from such adjustment. Any adjustment under this
Section 2(d) shall become effective at the close of business on the date
immediately after such Event of Default.

                  3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall
declare or make any dividend or other distribution of its assets (or rights to
acquire its assets) to holders of shares of Common Stock, by way of return of
capital or otherwise (including, without limitation, any distribution of cash,
stock or other securities, property or options by way of a dividend, spin off,
reclassification, corporate rearrangement, scheme of arrangement or other
similar transaction) (a "DISTRIBUTION"), at any time after the issuance of this
Warrant, then, in each such case:

                                      -9-

<PAGE>

                           (a) any Exercise Price in effect immediately prior to
the close of business on the record date fixed for the determination of holders
of shares of Common Stock entitled to receive the Distribution shall be reduced,
effective as of the close of business on such record date, to a price determined
by multiplying such Exercise Price by a fraction of which (i) the numerator
shall be the Closing Bid Price of the shares of Common Stock on the Trading Day
immediately preceding such record date minus the value of the Distribution (as
determined in good faith by the Company's Board of Directors) applicable to one
share of shares of Common Stock, and (ii) the denominator shall be the Closing
Bid Price of the shares of Common Stock on the Trading Day immediately preceding
such record date; and

                           (b) the number of Warrant Shares shall be increased
to a number of shares equal to the number of shares of Common Stock obtainable
immediately prior to the close of business on the record date fixed for the
determination of holders of shares of Common Stock entitled to receive the
Distribution multiplied by the reciprocal of the fraction set forth in the
immediately preceding paragraph (a); provided that in the event that the
Distribution is of shares of common stock ("OTHER SHARES OF COMMON STOCK") of a
company whose common shares are traded on a national securities exchange or a
national automated quotation system, then the Holder may elect to receive a
warrant to purchase Other Shares of Common Stock in lieu of an increase in the
number of Warrant Shares, the terms of which shall be identical to those of this
Warrant, except that such warrant shall be exercisable into the number of shares
of Other Shares of Common Stock that would have been payable to the Holder
pursuant to the Distribution had the Holder exercised this Warrant immediately
prior to such record date and with an aggregate exercise price equal to the
product of the amount by which the exercise price of this Warrant was decreased
with respect to the Distribution pursuant to the terms of the immediately
preceding paragraph (a) and the number of Warrant Shares calculated in
accordance with the first part of this paragraph (b).

                  4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.

                           (a) PURCHASE RIGHTS. In addition to any adjustments
pursuant to Section 2 above, if at any time the Company grants, issues or sells
any Options, Convertible Securities or rights to purchase stock, warrants,
securities or other property pro rata to the record holders of any class of
shares of Common Stock (the "PURCHASE RIGHTS"), then the Holder will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock acquirable upon complete exercise of this
Warrant (without regard to any limitations on the exercise of this Warrant)
immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of shares of Common Stock are to be determined for the
grant, issue or sale of such Purchase Rights.

                           (b) FUNDAMENTAL TRANSACTIONS. The Company shall not
enter into or be party to a Fundamental Transaction unless (i) the Successor
Entity assumes in writing all of the obligations of the Company under this

                                      -10-

<PAGE>

Warrant and the other Transaction Documents in accordance with the provisions of
this Section (4)(b) pursuant to written agreements in form and substance
satisfactory to the Required Holders and approved by the Required Holders prior
to such Fundamental Transaction, including agreements to deliver to each holder
of Warrants in exchange for such Warrants a security of the Successor Entity
evidenced by a written instrument substantially similar in form and substance to
this Warrant, including, without limitation, an adjusted exercise price equal to
the value for the shares of Common Stock reflected by the terms of such
Fundamental Transaction, and exercisable for a corresponding number of shares of
capital stock equivalent to the shares of Common Stock acquirable and receivable
upon exercise of this Warrant (without regard to any limitations on the exercise
of this Warrant) prior to such Fundamental Transaction, and satisfactory to the
Required Holders and (ii) the Successor Entity (including its Parent Entity) is
a publicly traded corporation whose common stock is quoted on or listed for
trading on an Eligible Market. Upon the occurrence of any Fundamental
Transaction, the Successor Entity shall succeed to, and be substituted for (so
that from and after the date of such Fundamental Transaction, the provisions of
this Warrant referring to the "Company" shall refer instead to the Successor
Entity), and may exercise every right and power of the Company and shall assume
all of the obligations of the Company under this Warrant with the same effect as
if such Successor Entity had been named as the Company herein. Upon consummation
of the Fundamental Transaction, the Successor Entity shall deliver to the Holder
confirmation that there shall be issued upon exercise of this Warrant at any
time after the consummation of the Fundamental Transaction, in lieu of the
shares of the Common Stock (or other securities, cash, assets or other property)
purchasable upon the exercise of the Warrant prior to such Fundamental
Transaction, such shares of stock, securities, cash, assets or any other
property whatsoever (including warrants or other purchase or subscription
rights) which the Holder would have been entitled to receive upon the happening
of such Fundamental Transaction had this Warrant been converted immediately
prior to such Fundamental Transaction, as adjusted in accordance with the
provisions of this Warrant. In addition to and not in substitution for any other
rights hereunder, prior to the consummation of any Fundamental Transaction
pursuant to which holders of shares of Common Stock are entitled to receive
securities or other assets with respect to or in exchange for shares of Common
Stock (a "CORPORATE EVENT"), the Company shall make appropriate provision to
insure that the Holder will thereafter have the right to receive upon an
exercise of this Warrant at any time after the consummation of the Fundamental
Transaction but prior to the Expiration Date, in lieu of the shares of the
Common Stock (or other securities, cash, assets or other property) purchasable
upon the exercise of the Warrant prior to such Fundamental Transaction, such
shares of stock, securities, cash, assets or any other property whatsoever
(including warrants or other purchase or subscription rights) which the Holder
would have been entitled to receive upon the happening of such Fundamental
Transaction had the Warrant been exercised immediately prior to such Fundamental
Transaction. Provision made pursuant to the preceding sentence shall be in a
form and substance reasonably satisfactory to the Required Holders. The
provisions of this Section shall apply similarly and equally to successive
Fundamental Transactions and Corporate Events and shall be applied without
regard to any limitations on the exercise of this Warrant.

                           (c) Notwithstanding the foregoing and the provisions
of Section 4(b) above, in the event of a Fundamental Transaction, if the Holder
has not exercised the Warrant in full prior to the consummation of the
Fundamental Transaction, then the Holder shall have the right to require such

                                      -11-

<PAGE>

Successor Entity to purchase this Warrant from the Holder by paying to the
Holder, simultaneously with the consummation of the Fundamental Transaction and
in lieu of the warrant referred to in Section 4(b), cash in an amount equal to
the value of the remaining unexercised portion of this Warrant on the date of
such consummation, which value shall be determined by use of the Black and
Scholes Option Pricing Model reflecting (i) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the remaining term
of this Warrant as of such date of request and (ii) an expected volatility equal
to the greater of 60% and the 100 day volatility obtained from the HVT function
on Bloomberg.

                  5. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as
otherwise specifically provided herein, the Holder, solely in such Person's
capacity as a holder of this Warrant, shall not be entitled to vote or receive
dividends or be deemed the holder of share capital of the Company for any
purpose, nor shall anything contained in this Warrant be construed to confer
upon the Holder, solely in such Person's capacity as the Holder of this Warrant,
any of the rights of a shareholder of the Company or any right to vote, give or
withhold consent to any corporate action (whether any reorganization, issue of
stock, reclassification of stock, consolidation, merger, conveyance or
otherwise), receive notice of meetings, receive dividends or subscription
rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares
which such Person is then entitled to receive upon the due exercise of this
Warrant. In addition, nothing contained in this Warrant shall be construed as
imposing any liabilities on the Holder to purchase any securities (upon exercise
of this Warrant or otherwise) or as a shareholder of the Company, whether such
liabilities are asserted by the Company or by creditors of the Company.
Notwithstanding this Section 6, the Company shall provide the Holder with copies
of the same notices and other information given to the shareholders of the
Company generally, contemporaneously with the giving thereof to the
shareholders.

                  6. NONCIRCUMVENTION. The Company hereby covenants and agrees
that the Company will not, by amendment of its Articles of Incorporation, Bylaws
or through any reorganization, transfer of assets, consolidation, merger, scheme
of arrangement, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
of this Warrant, and will at all times in good faith carry out all the
provisions of this Warrant and take all action as may be required to protect the
rights of the Holder. Without limiting the generality of the foregoing, the
Company (i) shall not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, (ii) shall take all such actions as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant, and
(iii) shall, so long as any of the SPA Warrants are outstanding, take all action
necessary to reserve and keep available out of its authorized and unissued
shares of Common Stock, solely for the purpose of effecting the exercise of the
SPA Warrants, prior to the Stockholder Approval Deadline (as defined in the
Securities Purchase Agreement), 100% of the number of shares of Common Stock as
shall from time to time be necessary to effect the exercise of the Series L SPA
Warrants then outstanding (without regard to any limitations on exercise) and,
from and after the Stockholder Approval Deadline, 130% of the number of shares
of Common Stock as shall from time to time be necessary to effect the exercise
of the SPA Warrants then outstanding (without regard to any limitations on
exercise). .

                  7. REISSUANCE OF WARRANTS.

                           (a) TRANSFER OF WARRANT. If this Warrant is to be
transferred, the Holder shall surrender this Warrant to the Company, whereupon
the Company will forthwith issue and deliver upon the order of the Holder a new
Warrant (in accordance with Section 7(d)), registered as the Holder may request,
representing the right to purchase the number of Warrant Shares being
transferred by the Holder and, if less then the total number of Warrant Shares
then underlying this Warrant is being transferred, a new Warrant (in accordance
with Section 7(d)) to the Holder representing the right to purchase the number
of Warrant Shares not being transferred.

by the Company of evidence reasonably satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant, and, in the case of loss,
theft or destruction, of any indemnification undertaking by the Holder to the
Company in customary form and, in the case of mutilation, upon surrender and
cancellation of this Warrant, the Company shall execute and deliver to the
Holder a new Warrant (in accordance with Section 7(d)) representing the right to
purchase the Warrant Shares then underlying this Warrant.

is exchangeable, upon the surrender hereof by the Holder at the principal office
of the Company, for a new Warrant or Warrants (in accordance with Section 7(d))
representing in the aggregate the right to purchase the number of Warrant Shares
then underlying this Warrant, and each such new Warrant will represent the right
to purchase such portion of such Warrant Shares as is designated by the Holder
at the time of such surrender; provided, however, that no Warrants for
fractional shares of Common Stock shall be given.

                           (d) ISSUANCE OF NEW WARRANTS. Whenever the Company is
required to issue a new Warrant pursuant to the terms of this Warrant, such new
Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as
indicated on the face of such new Warrant, the right to purchase the Warrant
Shares then underlying this Warrant (or in the case of a new Warrant being
issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated

Warrant, unless otherwise provided herein, such notice shall be given in

the public prior to or in conjunction with such notice being provided to the
Holder.

                  9. AMENDMENT AND WAIVER. Except as otherwise provided herein,
the provisions of this Warrant may be amended and the Company may take any
action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the written consent of the
Required Holders; provided that no such action may increase the exercise price
of any SPA Warrant or decrease the number of shares or class of stock obtainable
upon exercise of any SPA Warrant without the written consent of the Holder. No
such amendment shall be effective to the extent that it applies to less than all
of the holders of the SPA Warrants then outstanding.

construed and enforced in accordance with, and all questions concerning the
construction, validity, interpretation and performance of this Warrant shall be
governed by, the internal laws of the State of New York, without giving effect
to any choice of law or conflict of law provision or rule (whether of the State
of New York or any other jurisdictions) that would cause the application of the
laws of any jurisdictions other than the State of New York.

                  11. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be
jointly drafted by the Company and all the Buyers and shall not be construed
against any person as the drafter hereof. The headings of this Warrant are for
convenience of reference and shall not form part of, or affect the
interpretation of, this Warrant.

                  12. DISPUTE RESOLUTION. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, the Company shall submit the disputed determinations or arithmetic
calculations via facsimile within two Business Days of receipt of the Exercise
Notice giving rise to such dispute, as the case may be, to the Holder. If the
Holder and the Company are unable to agree upon such determination or
calculation of the Exercise Price or the Warrant Shares within three Business
Days of such disputed determination or arithmetic calculation being submitted to
the Holder, then the Company shall, within two Business Days submit via
facsimile (a) the disputed determination of the Exercise Price to an

                  13. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE
RELIEF. The remedies provided in this Warrant shall be cumulative and in
addition to all other remedies available under this Warrant and the other
Transaction Documents, at law or in equity (including a decree of specific
performance and/or other injunctive relief), and nothing herein shall limit the
right of the Holder right to pursue actual damages for any failure by the
Company to comply with the terms of this Warrant. The Company acknowledges that
a breach by it of its obligations hereunder will cause irreparable harm to the
Holder and that the remedy at law for any such breach may be inadequate. The
Company therefore agrees that, in the event of any such breach or threatened
breach, the holder of this Warrant shall be entitled, in addition to all other
available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being
required.

                  14. TRANSFER. This Warrant may be offered for sale, sold,
transferred or assigned without the consent of the Company, except as may
otherwise be required by Section 2(g) of the Securities Purchase Agreement.

the Weighted Average Price of such security on such date shall be the fair
market value as mutually determined by the Company and the Holder. If the
Company and the Holder are unable to agree upon the fair market value of such
security, then such dispute shall be resolved pursuant to Section 12. All such
determinations are to be appropriately adjusted for any stock dividend, stock
split, stock combination or other similar transaction during the applicable
calculation period.
