      (a)   Interest. The Company shall pay interest accruing on this Note
(from the date hereof) on all principal outstanding at the Interest Rate,
semi-annually on the Interest Payment Dates, commencing on November __, 2005,
in cash; provided that the Default Rate shall apply in the circumstances set
forth above. Notwithstanding the foregoing, if (and only if) there is
Effective Registration on the applicable Interest Payment Date, then the
Company may pay such interest, at the Company's option, (i) in fully paid and
nonassessable shares of Common Stock (such interest paid in such form being
herein called "PIK Interest") or (ii) in cash. PIK Interest shall be paid by
delivering to the Holder a number of shares of Common Stock ("PIK Interest
Shares") determined by dividing (x) the total aggregate dollar amount of
interest due on the applicable Interest Payment Date (rounded to the nearest
whole cent) by (y) the applicable PIK Interest Price. In order to deliver PIK
Interest Shares in lieu of cash on an Interest Payment Date, the Company must
deliver, on or before the fifteenth (15th) calendar day immediately prior to
such date, written notice to the Holder stating that the Company wishes to do
so (a "PIK Interest Notice"); in the event that the Company does not deliver a
PIK Interest Notice on or before such fifteenth (15th) day, the Company will
be deemed to have elected to pay the related interest in cash. The Holder
shall promptly thereafter deliver to the Company instructions designating
whether the Holder wishes to receive delivery of its PIK Interest Shares in
physical certificates (and, if so, at what address) or through DTC (similar to
that described in Section 3(b)(ii)), as long as no legend is required by the
terms of the Purchase Agreement to be imprinted on such PIK Interest Shares
(and, if so, the account number to be credited). If the Company wishes to
deliver PIK Interest Shares in lieu of cash with respect to accrued interest,
it must do so with respect to all (but not less than all) of such interest. A
PIK Interest Notice, once delivered by the Company, shall be irrevocable
unless there is not Effective Registration on the applicable Interest Payment
Date, in which case such notice shall be deemed revoked and the interest to
which such notice relates shall be payable in cash on the Interest Payment
Date. The Company shall not issue fractional shares of Common Stock to which
the Holder may become entitled pursuant to this subparagraph, but in lieu
thereof, the Company shall round the number of shares to be issued up to the
next whole number.

      (b)   Principal. The entire Principal Amount of this Note, plus any and
all default payments owing under the Transaction Documents but not previously
paid, shall become due and payable on the Final Maturity Date. Any principal
of this Note that is converted pursuant to Section 3 shall be applied to
reduce the principal payable under this Section 2(b).

      (c)   Prepayment.  At any time following the first anniversary of the
Issuance Date, upon delivery of a written notice to the Holder (a "Company
Prepayment Notice" and the date such notice is delivered by the Company, the
"Company Notice Date"), the Company shall be entitled to prepay all or any
portion of the outstanding Principal Amount of this Note, plus any accrued and
unpaid interest thereon, for an amount in cash equal to the sum of (i) 125% of
the Principal Amount of this Note to be prepaid, plus all accrued and unpaid
interest thereon, and (ii) all other amounts, costs, expenses and liquidated
damages due in respect of this Note.  Notwithstanding the foregoing, the
Company shall be entitled to deliver a Company Prepayment Notice and prepay
this Note pursuant to the terms of this subsection (c) only if (i) there is
Effective Registration on the Company Notice Date and it is expected that
Effective Registration will continue for at least 20 Trading Days after the
Company Notice Date, and (ii) conversion by the Holder pursuant to Section 3
of the portion of this Note that is being prepaid would not cause the Holder's
beneficial ownership of shares of Common Stock to exceed the limits set forth
in Section 3.13 of the Purchase Agreement, and (iii) the average daily trading
volume for the Common Stock during the 20 consecutive Trading Days immediately
preceding (but not including) the date that the Holder receives the Company
Prepayment Notice exceeded 200,000 shares. The Holder may, within ten Trading
Days of its receipt of the Company Prepayment Notice, convert pursuant to
Section 3, at the then effective Conversion Price, any portion of the
outstanding principal amount of this Note being prepaid and any accrued and
unpaid interest thereon subject to the Company Prepayment Notice.

      Section 3.  Conversion.

      (a)   Conversion Rights.  Upon the terms and subject to the conditions
hereof, the Holder shall have the right, at the Holder's option, to convert
the outstanding Principal Amount and accrued and unpaid interest thereon into
Common Stock, in whole at any time or in part from time to time, by delivering
to the Company a duly executed notice of conversion in the form attached
hereto as Exhibit A (the "Optional Conversion Notice"), which may be
transmitted by telephone line facsimile transmission. In addition, upon
written notice by the Company to the Holder (the "Mandatory Conversion
Notice"), the Company may cause the Holder to convert all (but not less than
all) of the outstanding Principal Amount and accrued and unpaid interest
thereon into Common Stock, if (and only if) (i) there is Effective
Registration on the date that the Holder receives the Mandatory Conversion
Notice, and (ii) the closing price of the Common Stock exceeded 200% of the
Conversion Price then in effect for any 20 out of 30 consecutive Trading Days
immediately preceding (but not including) the date that the Holder receives
the Mandatory Conversion Notice, and (iii) the average daily trading volume
for the Common Stock during the 20 consecutive Trading Days immediately
preceding (but not including) the date that the Holder receives the Mandatory
Conversion Notice exceeded 200,000 shares. Notwithstanding anything to the
contrary herein, this Note and the outstanding Principal Amount hereunder
shall not be convertible into Common Stock at any time to the extent, and only
to the extent, that such conversion at such time would result in the Holder
exceeding the limitation contained in, or otherwise violating the provisions
of, Section 3.13 of the Purchase Agreement.

      (b)   Common Stock Issuance Upon Conversion.

            (i)   Conversion Procedures. Upon any conversion of this Note
pursuant to Section 3(a) above, the outstanding Principal Amount being
converted and accrued and unpaid interest thereon to the applicable Conversion
Date shall be converted into such number of fully paid, validly issued and
non-assessable shares of Common Stock, free of any liens, claims and
encumbrances, as is determined by dividing the outstanding Principal Amount
being converted and accrued and unpaid interest thereon to the applicable
Conversion Date by the then applicable Conversion Price. The date of any
Conversion Notice hereunder shall be referred to herein as the "Conversion
Date".  If a conversion under this Note cannot be effected in full for any
reason, or if the Holder is converting less than all of the outstanding
Principal Amount hereunder pursuant to a Conversion Notice, the Company shall,
upon request of the Holder, promptly deliver to the Holder (but no later than
five Trading Days after the surrender of this Note to the Company) a new Note
having a Principal Amount equal to the amount of such outstanding Principal
Amount as has not been converted. The Holder shall not be required physically
to surrender this Note to the Company upon any conversion unless the full
outstanding Principal Amount of this Note is being converted or repaid. The
Holder and the Company shall maintain records showing the outstanding
Principal Amount so converted and repaid and the dates of such conversions or
repayments 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 each such conversion or repayment. The Holder agrees that, if the
outstanding Principal Amount of this Note is less than the Principal Amount
stated on the face of this Note, the Holder will not voluntarily transfer this
Note at any time when no Event of Default has occurred and is continuing
without first surrendering this Note to the Company for issuance, without
charge to the Holder, of a replacement instrument that reflects the
outstanding Principal Amount of this Note. The Company will deliver such
replacement instrument to the Holder as promptly as practical, but in no event
later than three Trading Days, after surrender by the Holder.

            (ii)   Stock Certificates or DWAC.  The Company will deliver to
the Holder not later than three (3) Trading Days after a particular Conversion
Date, a certificate or certificates, which shall be free of restrictive
legends and trading restrictions (except to the extent permitted under Article
V of the Purchase Agreement), for the number of shares of Common Stock
issuable upon such conversion of this Note.  In lieu of delivering physical
certificates for the shares of Common Stock issuable upon any conversion of
this Note, provided the Company's transfer agent is participating in the
Depository Trust Company ("DTC") Fast Automated Securities Transfer ("FAST")
program, upon request of the Holder, the Company shall use commercially
reasonable efforts to cause its transfer agent electronically to transmit such
shares issuable upon conversion to the Holder (or its designee), by crediting
the account of the Holder's (or such designee's) broker with DTC through its
Deposit Withdrawal Agent Commission system (provided that the same time
periods herein as for stock certificates shall apply).  If in the case of any
conversion hereunder, such shares are not delivered to or as directed by the
Holder by the third Trading Day after the applicable Conversion Date, the
Holder shall be entitled by written notice to the Company at any time on or
before its receipt of such shares, to rescind such conversion, in which event
the Company shall immediately return this Note to the Holder if the Holder has
tendered it to the Company in connection with such conversion. If the Holder
notifies the Company that the Holder has not received such shares (free of any
restrictions on transfer or legends except as permitted by Article V of the
Purchase Agreement) within three Trading Days after a particular Conversion
Date (each, a "Holder Share Notice") and the Holder does not receive such
shares (free of any restrictions on transfer or legends except as permitted by
Article V of the Purchase Agreement) within two Trading Days after giving such
Holder Share Notice, then, in addition to any other liability the Company may
have, the Company shall pay to the Holder, in cash, an amount, computed at the
rate of 2% of the outstanding Principal Amount per month, for the period such
failure continues (the "Conversion Delay Payments"). A Holder Share Notice may
be given by telephone, confirmed in writing, or e-mail to the Company's Chief
Financial Officer or General Counsel or Chief Executive Officer. The Company's
obligation to issue and deliver such shares of Common Stock upon conversion of
this Note shall be absolute and unconditional, irrespective of the absence of
any action by the Holder to enforce the same, of any waiver or consent with
respect to any provision hereof, the recovery of any judgment against any
Person or any action to enforce the same, any failure or delay in the
enforcement of any other obligation of the Company to the Holder, or any
setoff, counterclaim, recoupment, limitation or termination, or any breach or
alleged breach by the Holder or any other Person of any obligation to the
Company or any violation or alleged violation of law by the Holder or any
other Person, and irrespective of any other circumstance which might otherwise
limit such obligation of the Company to the Holder in connection with such
exercise.

            (iii)   Liability for Late Delivery; Force Majeure.  If in any
case the Company shall fail to issue and deliver the shares of Common Stock to
the Holder pursuant to this Note on the due date therefor, in addition to any
other liabilities the Company may have hereunder and under applicable law (A)
the Company shall pay or reimburse the Holder on demand for all out-of-pocket
expenses, including, without limitation, reasonable fees and expenses of legal
counsel, incurred by the Holder as a result of such failure, so long as the
Holder shall have given the Company a Holder Share Notice with respect to such
shares of Common Stock, (B) if as a result of such failure the Holder shall
suffer any direct damages or liabilities from such failure (including, without
limitation, margin interest and the cost of purchasing securities to cover a
sale (whether by the Holder or the Holder's securities broker) or borrowing of
shares of Common Stock by the Holder for purposes of settling any trade
involving a sale of shares of Common Stock made by the Holder during the
period beginning on the Issuance Date and ending on the date the Company
delivers or causes to be delivered to the Holder such shares of Common Stock),
then the Company shall upon demand of the Holder pay to the Holder an amount
equal to the actual, direct out-of-pocket damages and liabilities suffered by
the Holder by reason thereof which the Holder documents to the reasonable
satisfaction of the Company, so long as the Holder shall have given the
Company a Holder Share Notice with respect to such shares of Common Stock, and
(C) the Holder may by written notice (which may be given by mail, courier,
personal service or telephone line facsimile transmission) or oral notice
(promptly confirmed in writing), given at any time prior to delivery to the
Holder of the shares of Common Stock issuable in connection with any exercise
of the Holder's rights by reason of which such shares are deliverable, rescind
such exercise in whole or in part, in which case the Holder shall thereafter
be entitled to exercise its rights with respect to that portion of this Note
as to which such exercise is so rescinded and to exercise its other rights and
remedies with respect to such failure by the Company.  Notwithstanding the
foregoing and Section 3(b)(ii), (x) the Company shall not be liable to the
Holder under clauses (A) and (B) of the immediately preceding sentence or (y)
for Conversion Delay Payments, in either such case of the preceding clause (x)
or (y) to the extent the failure of the Company to deliver or to cause to be
delivered such shares of Common Stock results from a Force Majeure Event (it
being understood that the action or failure to act of the Company's Transfer
Agent shall not be deemed a Force Majeure Event unless outside the control of
such Transfer Agent or resulting from the bankruptcy, liquidation or
reorganization of such Transfer Agent under any bankruptcy, insolvency or
other similar law). The Holder shall notify the Company in writing (or by
telephone conversation, confirmed in writing) as promptly as practicable
following the third Trading Day after the due date for delivery to it of
shares of Common Stock under this Note if the Holder becomes aware that such
shares of Common Stock so issuable have not been received as provided herein,
but any failure so to give such notice shall not affect the Holder's rights
under this Note or otherwise. If pursuant to this Section 3(b)(iii) the
Company is relieved of its obligation to make Conversion Delay Payments, then
the Principal Amount of this Note for which a Conversion Notice has been given
and for which the Company has not issued the shares of Common Stock within the
period provided in Section 3(b)(ii) shall continue to bear interest at the
applicable rate provided in this Note from the applicable Conversion Date to
the date the Company so issues such shares of Common Stock.

      (c)   Conversion Price Adjustments.

            (i)   Stock Dividends, Splits and Combinations. In the event that
the Company shall (A) pay a dividend or make a distribution to all its
stockholders, in shares of Common Stock, on any class of capital stock of the
Company or any subsidiary which is not directly or indirectly wholly owned by
the Company, (B) split or subdivide its outstanding Common Stock into a
greater number of shares, or (C) combine its outstanding Common Stock into a
smaller number of shares, then in each such case the Conversion Price in
effect immediately prior thereto shall be adjusted so that the Holder of this
Note thereafter surrendered for conversion shall be entitled to receive the
number of shares of Common Stock that such Holder would have owned or have
been entitled to receive after the occurrence of any of the events described
above had this Note been fully converted immediately prior to the occurrence
of such event. An adjustment made pursuant to this Section 3(c)(i) shall
become effective immediately after the close of business on the record date in
the case of a dividend or distribution and shall become effective immediately
after the close of business on the effective date in the case of such
subdivision, split or combination, as the case may be. Any shares of Common
Stock issuable in payment of a dividend shall be deemed to have been issued
immediately prior to the close of business on the record date for such
dividend for purposes of calculating the number of outstanding shares of
Common Stock under clause (ii) below.

            (ii)   Adjustment for Certain Issuances.

            (A)   In the event that the Company shall commit to issue or
distribute New Securities, in any such case at a price per share less than the
Current Market Price per share on the earliest of (1) the date the Company
shall enter into a firm contract for such issuance or distribution, (2) the
record date for the determination of stockholders entitled to receive any such
New Securities, if applicable, or (3) the date of actual issuance or
distribution of any such New Securities (provided that the issuance of Common
Stock upon the exercise of New Securities that are rights, warrants, options
or convertible or exchangeable securities ("New Derivative Securities") will
not cause an adjustment in the Conversion Price if no such adjustment would
have been required at the time such New Derivative Security was issued), then
the Conversion Price in effect immediately prior to such earliest date shall
be adjusted so that the new Conversion Price shall equal the price determined
by multiplying the Conversion Price in effect immediately prior to such
earliest date by the fraction:

     (x) whose numerator shall be (I) the number of shares of Common Stock
     outstanding on such date (on a fully-diluted basis after giving effect to
     any securities (other than this Note) convertible or exchangeable into
     Common Stock) plus (II) the number of shares of Common Stock which the
     aggregate offering price of the total number of New Securities so offered
     would have purchased at such Current Market Price (such amount, with
     respect to any New Derivative Securities, determined by multiplying the
     total number of shares of Common Stock subject thereto by the exercise
     price of such New Derivative Securities, and dividing the product so
     obtained by such Current Market Price), and

     (y) whose denominator shall be (I) the number of shares of Common Stock
     outstanding on such date (on a fully-diluted basis after giving effect to
     any securities (other than this Note) convertible or exchangeable into
     Common Stock) plus (II) the number of additional shares of Common Stock
     to be issued or distributed or receivable upon exercise of any such New
     Derivative Security.

Such adjustment shall be made successively whenever any such New Securities
are issued. In determining whether any New Derivative Securities entitle the
holders to subscribe for or purchase shares of Common Stock at less than such
Current Market Price, and in determining the aggregate offering price of
shares of Common Stock so issued, there shall be taken into account any
consideration received by the Company for such Common Stock or New Derivative
Securities, the value of such consideration, if other than cash, to be
determined by the Board of Directors, whose determination shall be conclusive
and described in a certificate filed with the records of corporate proceedings
of the Company. If any New Derivative Security to purchase or acquire Common
Stock, the issuance of which resulted in an adjustment in the Conversion Price
pursuant to this subsection (A) shall expire and shall not have been
exercised, the Conversion Price shall immediately upon such expiration be
recomputed to the Conversion Price which would have been in effect had the
adjustment of the Conversion Price made upon the issuance of such New
Derivative Security been made on the basis of offering for subscription,
purchase or issuance, as the case may be, only of that number of shares of
Common Stock actually purchased or issued upon the actual exercise of such New
Derivative Security.

            (B) In the event that the 30-day moving average closing price of
the Common Stock ending on the Reset Date is less than the Conversion Price in
effect immediately prior to the Reset Date, then the Conversion Price shall be
adjusted so that the Conversion Price immediately following the Reset Date
shall equal such 30-day moving average closing price of the Common Stock.
Notwithstanding the foregoing, in no event shall the Conversion Price be
adjusted pursuant to this subsection (B) below $0.50, subject to adjustment
for stock splits, subdivisions, combinations and the like effected after the
Issuance Date.

            (C)   In the event that the Company shall issue or distribute New
Securities, in any such case at a price per share less than $2.50 or that
would entitle the holders of the New Securities to subscribe for or purchase
shares of Common Stock at less than $2.50 per share (provided that the
issuance of Common Stock upon the exercise of New Derivative Securities will
not cause an adjustment in the Conversion Price if no such adjustment would
have been required at the time such New Derivative Security was issued), then
the Conversion Price in effect immediately prior thereto shall be adjusted so
that the Conversion Price shall equal the price at which the Company issues or
distributes such New Securities (or the price at which the holders of the New
Securities are entitled to subscribe for or purchase shares of Common Stock).
Each such adjustment shall be made successively whenever any such New
Securities are issued. In determining whether any New Derivative Securities
entitle the holders to subscribe for or purchase shares of Common Stock at
less than $2.50 per share, there shall be taken into account any consideration
received by the Company for such New Derivative Securities, the value of such
consideration, if other than cash, to be determined in good faith by the Board
of Directors, whose determination shall be conclusive and described in a
certificate filed with the records of corporate proceedings of the Company.
Notwithstanding the foregoing, in no event shall an adjustment be made under
this subsection (C) if such adjustment would result in raising the
then-effective Conversion Price.

            (iii)   Rounding of Adjustments. No adjustment in the Conversion
Price shall be required unless the adjustment would require an increase or
decrease of at least 1% in the Conversion Price then in effect; provided,
however, that any adjustments that by reason of this Section 3(c) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Section 3 or Section 2
shall be made to the nearest cent or nearest 1/100th of a share.

            (iv)   Notice of Adjustments. Whenever the Conversion Price is
adjusted pursuant to this Section 3(c), the Company shall promptly deliver to
the Holder a notice setting forth the Conversion Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment,
provided that any failure to so provide such notice shall not affect the
automatic adjustment hereunder.

            (v)   Change in Control Transactions. In case of any Change in
Control Transaction, the Holder shall have the right thereafter, at its
option, (A) to convert this Note, in whole or in part, at the then applicable
Conversion Price into the shares of stock and other securities, cash and/or
property receivable upon or deemed to be held by holders of Common Stock
following such Change in Control Transaction, and the Holder shall be entitled
upon such event to receive such amount of securities, cash or property as the
shares of the Common Stock of the Company into which this Note could have been
converted immediately prior to such Change in Control Transaction would have
been entitled if such conversion were permitted (determined without regard to
any limitations contained in Section 3.13 of the Purchase Agreement), subject
to such further applicable adjustments set forth in this Section 3, or (B) to
require the Company or its successor to redeem this Note, in whole or in part,
at a redemption price equal to 125% of the outstanding Principal Amount being
redeemed, plus accrued interest thereon. The terms of any such Change in
Control Transaction shall include such terms so as to continue to give to the
Holder the right to receive the amount of securities, cash and/or property
upon any conversion or redemption following such Change in Control Transaction
to which a holder of the number of shares of Common Stock deliverable upon
conversion of this Note immediately prior to such Change in Control
Transaction would have been entitled to receive in such Change in Control
Transaction and if such Holder had continued to hold such securities, cash
and/or property until the date of such conversion or redemption, and interest
payable hereunder after such Change in Control Transaction shall be paid in
cash or such new securities and/or property, at the Holder's option. This
provision shall similarly apply to successive reclassifications,
consolidations, mergers, amalgamations, sales, transfers or share exchanges.

            (vi)   Notice of Certain Events.  If:

                   A.   the Company shall declare a dividend (or any other
distribution) on its Common Stock; or

                   B.   the Company shall declare a special nonrecurring cash
dividend on or a tender offer for, offer to purchase or redemption of its
Common Stock; or

                   C.   the Company shall authorize the granting to all
holders of the Common Stock rights or warrants to subscribe for or purchase
any shares of capital stock of any class or of any rights; or

                   D.   the approval of any stockholders of the Company shall
be required in connection with any reclassification of the Common Stock of the
Company, any consolidation, amalgamation or merger to which the Company is a
party, any sale or transfer of all or substantially all of the assets of the
Company, of any compulsory share of exchange whereby the Common Stock is
converted into other securities, cash or property; or

                   E.   the Company shall authorize the voluntary or
involuntary dissolution, liquidation or winding up of the affairs of the
Company; or

                   F.   there exists an agreement to which the Company is a
party or by which it is bound providing for a Change in Control Transaction,
or a Change in Control Transaction has occurred;

then the Company shall cause to be filed at each office or agency maintained
for the purpose of conversion of this Note, and shall cause to be mailed to
the Holder at its last address as it shall appear upon the books of the
Company, on or prior to the date notice of such matter to the Company's
stockholders generally is given, a notice stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution, tender
offer, offer to purchase, redemption, rights or warrants, or if a record is
not to be taken, the date as of which the holders of Common Stock of record to
be entitled to such dividend, distributions, tender offer, offer to purchase,
redemption, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, amalgamation, merger, sale, transfer,
share exchange or Change in Control Transaction is expected to become
effective or close, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, amalgamation, merger, sale, transfer, share
exchange or Change in Control Transaction.

      (d)   Reservation and Issuance of Underlying Securities. The Company
covenants that it will at all times reserve from its authorized and unissued
Common Stock a sufficient number of shares solely for the purpose of issuance
upon conversion in full of this Note, free from preemptive rights or any other
actual contingent purchase rights of persons other than the Holder (subject to
any additional requirements of the Company as to reservation of such shares
set forth in the Purchase Agreement and taking into account the adjustments
under this Section 3, but determined without regard to any ownership
limitations contained in the Purchase Agreement).  The Company represents,
warrants and covenants that all shares of Common Stock that shall be so
issuable shall, upon issue, be duly authorized, validly issued, fully paid,
and nonassessable.

      (e)   No Fractions. Upon a conversion hereunder the Company shall not be
required to issue stock certificates for a fraction of a share of Common
Stock, but may if otherwise permitted, make a cash payment in respect of any
fraction of a share based on the Current Market Price of a share of Common
Stock at such time.  If the Company elects not, or is unable, to make such a
cash payment, the Holder shall be entitled to receive, in lieu of the fraction
of a share, one whole share of Common Stock.

      (f)   Charges, Taxes and Expenses.  Issuance of shares of Common Stock
upon the conversion of this Note shall be made without charge to the Holder
for any issue or transfer tax or other incidental expense in respect of the
issuance of such shares, all of which taxes and expenses shall be paid by the
Company, and such shares shall be issued in the name of the Holder or in such
name or names as may be directed by the Holder; provided, however, that in the
event certificates for shares of Common Stock are to be issued in a name other
than the name of the Holder, the applicable Conversion Notice, when given for
such conversion shall be accompanied or followed by an assignment form for the
applicable portion of this Note or such shares, as the case may be; and
provided further, that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any such transfer.

      (g)   Cancellation. After the entire Principal Amount (including accrued
but unpaid interest and default payments at any time owed on this Note) has
been paid in full or converted into Common Stock, this Note shall
automatically be deemed canceled and the Holder shall promptly surrender this
Note to the Company at the Company's principal executive offices; provided,
however, that the failure to surrender this Note shall not delay or limit such
cancellation.

      (h)   Notice Procedures. Any and all notices or other communications or
deliveries to be provided by the Holder under this Note, including, without
limitation, any Conversion Notice, shall be in writing and delivered
personally, by confirmed facsimile, or by a nationally recognized overnight
courier service to the Company at the facsimile telephone number or address of
the principal place of business of the Company as set forth in, or provided
pursuant to, the Purchase Agreement.  Any and all notices or other
communications or deliveries to be provided by the Company hereunder shall be
in writing and delivered personally, by facsimile, or by a nationally
recognized overnight courier service addressed to the Holder at the facsimile
telephone number or address of the Holder appearing on the books of the
Company, or if no such facsimile telephone number or address appears, at the
principal place of business of the Holder. Any notice or other communication
or deliveries hereunder shall be deemed delivered (i) upon receipt, when
delivered personally, (ii) when sent by facsimile, upon receipt if received on
a Business Day prior to 5:00 p.m. (Mountain Time), or on the first Business
Day following such receipt if received on a Business Day after 5:00 p.m.
(Mountain Time) or on a day that is not a Business Day or (iii) upon receipt,
when deposited with a nationally recognized overnight courier service.

      Section 4.   Defaults and Remedies.

      (a)   Events of Default.   An "Event of Default" is:  (i) a failure to
pay any Principal Amount of this Note when due, whether at the Final Maturity
Date or otherwise, (ii) a failure to pay any interest due on this Note on the
date such payment is due, which failure continues for two Business Days (or
ten Business Days if such failure results from a Force Majeure Event or if the
Company can prove that funds were in fact wired from the Company's account by
the due date); (iii) a failure timely to issue Underlying Shares upon and in
accordance with terms hereof, which failure continues for ten Business Days
after the Company has received written notice from the Holder informing the
Company that it has failed to issue shares or deliver stock certificates prior
to the fifth Business Day following the applicable Conversion Date; (iv)
failure by the Company for 20 days (or 90 days if such failure results from a
Force Majeure Event) after written notice has been received by the Company
from the Holder to comply with any material provision (other than as provided
in the immediately preceding clauses (i), (ii) and (iii)) of any of this Note
or any other Transaction Document (including, without limitation, the failure
to redeem this Note upon the Holder's request following a Change in Control
Transaction pursuant to Section 3(c)(v)); (v) a material breach by the Company
of its representations or warranties in this Note or in any other Transaction
Document that continues for 10 days after written notice to the Company; (vi)
any default after any cure period under, or acceleration prior to maturity of,
any note, mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any indebtedness for money borrowed
by the Company for in excess of $1 million, or for money borrowed the
repayment of which is guaranteed by the Company for in excess of $1 million,
whether such indebtedness or guarantee now exists or shall be created
hereafter; (vii) if the Company is subject to any Bankruptcy Event; (viii) if
the Registration Statement required by Section 2 of the Registration Rights
Agreement is not declared effective by the SEC within 150 days following the
Closing Date; (ix) any security interest or lien purported to be created by
the Security Agreement shall cease to be in full force and effect with respect
to a material portion of the collateral thereunder or any such security
interest or lien shall be asserted by the Company or any Subsidiary of the
Company not to be a valid, perfected, first priority (except as otherwise
permitted by the Transaction Documents) security interest in or lien on the
collateral covered thereby, and such security interest or lien is not restored
to full force and effect within 10 days after notice to the Company; or (x)
any Transaction Document or any material provisions thereof shall at any time
and for any reason be declared by a court of competent jurisdiction to be null
and void, or the Company or any Subsidiary of the Company shall repudiate or
deny any portion of its liabilities or obligations thereunder.

      (b)   Remedies. If an Event of Default occurs and is continuing, the
Holder may declare all of the then outstanding Principal Amount of this Note,
and any accrued and unpaid interest thereon, to be due and payable immediately
in cash, except that in the case of an Event of Default arising from events
described in clauses (vi) and (vii) of Section 4(a), this Note shall become
automatically due and payable without further action or notice, and the Holder
may exercise all other rights and remedies available at law or in equity. In
the event of such acceleration, the amount due and owing to the Holder shall
be 125% of the outstanding Principal Amount of this Note (plus all accrued and
unpaid interest, if any). In any event the Company shall pay interest on such
amount in cash at the Default Rate to the Holder if such amount is not paid
within one Business Day after such acceleration. The remedies under this Note
shall be cumulative.

      Section 5.   Certain Covenants; General.

      (a)   Rule 144A Information Requirement. Within the period prior to the
expiration of the holding period applicable to sales hereof under Rule 144(k)
under the Securities Act (or any successor provision), the Company covenants
and agrees that it shall, during any period in which it is not subject to
Section 13 or 15(d) under the Exchange Act, make available to the Holder and
any prospective purchaser of this Note from the Holder, the information
required pursuant to Rule 144A(d)(4) under the Securities Act upon the request
of the Holder and it will take such further action as the Holder may
reasonably request, all to the extent required from time to time to enable the
Holder to sell this Note without registration under the Securities Act within
the limitations of the exemption provided by Rule 144A, as Rule 144A may be
amended from time to time.  Upon the request of the Holder, the Company will
deliver to the Holder a written statement as to whether it has complied with
such requirements.

      (b)   Payment of Expenses. The Company agrees to pay all charges and
expenses, including attorneys' fees and expenses, which may be incurred by the
Holder in seeking to enforce this Note.

      (c)   Savings Clause. In case any provision of this Note is held by a
court of competent jurisdiction to be excessive in scope or otherwise invalid
or unenforceable, such provision shall be adjusted rather than voided, if
possible, so that it is enforceable to the maximum extent possible, and the
validity and enforceability of the remaining provisions of this Note will not
in any way be affected or impaired thereby.  In no event shall the amount of
interest paid hereunder exceed the maximum rate of interest on the unpaid
principal balance hereof allowable by applicable law.  If any sum is collected
in excess of the applicable maximum rate, the excess collected shall be
applied to reduce the principal debt.  If the interest actually collected
hereunder is still in excess of the applicable maximum rate, the interest rate
shall be reduced so as not to exceed the maximum allowable under law.

      (d)   Amendment. Neither this Note nor any term hereof may be amended,
waived, discharged or terminated other than by a written instrument signed by
the Company and Holder.

      (e)   Assignment, Etc. The Holder may assign or transfer this Note,
subject to compliance with applicable securities laws, without the consent of
the Company. The Holder shall notify the Company of any such assignment or
transfer promptly. The Company may not assign its rights or obligations under
this Note.  This Note shall be binding upon the Company and its successors and
shall inure to the benefit of the Holder and its successors and permitted
assigns.

      (f)   No Waiver.  No failure on the part of the Holder to exercise, and
no delay in exercising any right, remedy or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise by the Holder of any
right, remedy or power hereunder preclude any other or future exercise of any
other right, remedy or power.  Each and every right, remedy or power hereby
granted to the Holder or allowed it by law or other agreement shall be
cumulative and not exclusive of any other, and may be exercised by the Holder
from time to time.

      (g)   Governing Law; Jurisdiction.

            (i)   Governing Law.  THIS NOTE WILL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT REGARD TO ANY
CONFLICTS OF LAWS PROVISIONS THEREOF THAT WOULD OTHERWISE REQUIRE THE
APPLICATION OF THE LAW OF ANY OTHER JURISDICTION.

            (ii)   Jurisdiction. The Company (i) hereby irrevocably submits to
the exclusive jurisdiction of the United States District Court sitting in the
Northern District of Texas and the courts of the State of Texas located in
Dallas, Texas, for the purposes of any suit, action or proceeding arising out
of or relating to this Note or the transactions contemplated hereby, and (ii)
hereby waives, and agrees not to assert in any such suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
such court, that the suit, action or proceeding is brought in an inconvenient
forum or that the venue of the suit, action or proceeding is improper. The
Company consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to the Company at the address in effect
for notices to it under the Purchase Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof.
Nothing in this Section 5(g)(ii) shall affect or limit any right to serve
process in any other manner permitted by law. The Company hereby agrees that
if the Holder is the prevailing party in any suit, action or proceeding
arising out of or relating to this Note, the Holder shall be entitled to
reimbursement for legal fees from the Company.

            (iii)   NO JURY TRIAL. The Company knowingly and voluntarily
waives any and all rights it may have to a trial by jury with respect to any
litigation based on, or arising out of, under, or in connection with, this
Note.

      (h)   Replacement Notes. This Note may be exchanged by Holder at any
time and from time to time for a Note or Notes with different denominations
representing an equal aggregate outstanding Principal Amount, as reasonably
requested by Holder, upon surrendering the same.  No service charge will be
made for such registration or exchange.  In the event that Holder notifies the
Company that this Note has been lost, stolen or destroyed, a replacement Note
identical in all respects to the original Note (except for registration number
and Principal Amount, if different than that shown on the original Note),
shall be issued to the Holder, without requirement for any surety bond,
provided that the Holder executes and delivers to the Company an agreement
reasonably satisfactory to the Company to indemnify the Company from any loss
incurred by it in connection with this Note.

                     [Signature Page Follows]

      IN WITNESS WHEREOF, the Company has caused this Note to be duly executed
on the day and in the year first above written.
