Section 3.     Redemption.
     (a)  Mandatory Redemption.  If this Series 1
     Bridge Note is outstanding on the Maturity
     Date, this Series 1 Bridge Note shall be due
     and payable as follows:

              (i)  if on the Maturity Date or within
         four (4) business days thereafter a
         Registration Statement is effective with
         respect to the Conversion Shares, the Company
         shall give written notice to Holder of its
         intent to redeem the then outstanding
         principal amount of this Series 1 Bridge
         Note, which notice shall state the election
         of the Company to pay the redemption price in
         cash or by conversion of this Series 1 Bridge
         Note into Common Stock, in the manner
         contemplated by Section 3(c) hereof.
         Regardless of the manner in which paid, the
         redemption price (the "Maturity Date
         Redemption Price") shall be equal to 120% of
         the then outstanding principal amount of this
         Series 1 Bridge Note plus accrued and unpaid
         interest thereon at the Note Rate through and
         including the Maturity Date if redemption
         occurs on the Maturity Date or within four
         (4) days, thereafter, and if occurring later
         than four business days after the Maturity
         Date shall be equal to 125% of the then
         outstanding principal amount of this Series 1
         Bridge Note plus accrued and unpaid interest
         thereon at the Note Rate through and
         including the Maturity Date and at the
         Default Rate after the Maturity Date through
         and including the date the payment is
         disbursed (whether by issuance of Conversion
         Shares or a payment in cash).

              (ii) if on the Maturity Date or within
         four (4) business days thereafter a
         Registration Statement is not effective with
         respect to the Conversion Shares, Holder may,
         in addition to all other rights and remedies
         of Holder hereunder and under the Purchase
         Agreement, elect to make written demand to
         the Company to redeem, all or part of the
         then outstanding principal under this Series
         1 Bridge Note.  Such demand shall specify
         Holder's election to accept payment of the
         redemption price in cash or by conversion of
         this Series 1 Bridge Note into Common Stock,
         in the manner contemplated by Section 3(c)
         hereof.  The Company shall have two (2)
         business days after its receipt of such
         demand to confirm its intention to redeem
         this Series 1 Bridge Note by tendering to
         Holder either (A) cash or (B) Conversion
         Shares (as specified in Holder's demand), in
         the manner contemplated by Section 3(c)
         hereof.  In either case the redemption price
         shall be equal to the Maturity Date
         Redemption Price.

              (iii)     The date of any redemption
         under either subparagraph (i) or (ii) above
         shall be referred to as a "Redemption Date."

     and after the Original Issue Date up to but
     not including the Maturity Date, the Company
     may, at its option, call and redeem this

              (ii) At least ten (10) days before a
         Voluntary Redemption, the Company shall mail
         a notice of redemption to Holder, stating
         (A) the redemption date, which shall be a

              (iv) The Company may, at its option,

         Holder present the Series 1 Bridge Notes to
         the Person specified in paragraph (ii) above
         for surrender.

              (v)  No Voluntary Redemption of this
         Series 1 Bridge Note can be effected after
         the 209th day after the Original Issue Date.
     (c)  Conversion into Common Stock in Lieu of
     Payments.

              (i)  In lieu of payment of cash to
         Holder pursuant to Section 3(a)(i) hereof and
         Section 3(b) hereof, if a Registration
         Statement is in effect with respect to the
         Conversion Shares the Company may elect to
         pay all or part of the Maturity Date
         Redemption Price or the Voluntary Redemption
         Price in Conversion Shares, under the terms
         of Section 3(d) hereof.

              (ii) In lieu of cash, pursuant to
         Section 3(a)(ii) hereof, Holder may require
         the Company to pay all or part of the
         Maturity Date Redemption Price in Conversion
         Shares, under the terms of Section 3(d)
         hereof.
     The Repricing Warrant shall apply to each
     share of Common Stock received by Holder
     pursuant to this Section 3(c).
     (d)  The number of shares of Common Stock
     issuable in payment of the Maturity Date
     Redemption Price or the Voluntary Redemption
     Price is equal to the quotient of the
     Maturity Date Redemption Price or the
     Voluntary Redemption Price (as the case may
     be) divided by $6.0875 (the "Conversion
     Price") {5 day average Closing Bid Price
     prior to Original Issue Date}.  Fractional
     shares will not be issued.  In lieu of any
     fraction of a share, the Company shall
     deliver its check for the dollar amount of
     the less-than full share remainder.

Section 4.     Method of Payment.
     (a)  Interest accruing through and including
     the Maturity Date shall be computed at the
     Note Rate.  Interest accruing after the
     Maturity Date shall be computed at the
     Default Rate. Accrued and unpaid interest
     shall be due and payable at the time the
     principal and premium of this Series 1 Bridge
     Note is paid.  All such interest shall be
     computed on the basis of the actual number of
     days elapsed during any interest period in a
     year of 360 days.  Interest shall begin to
     accrue on the Original Issue Date.
     (b)  The Company shall pay interest and
     principal on this Series 1 Bridge Note
     (except defaulted interest) to the Person who
     is the registered Holder of this Series 1
     Bridge Note on the day on which the interest
     or principal payment is due.  If the Company
     defaults in a payment of interest on this
     Series 1 Bridge Note, it may pay the
     defaulted interest, to the Person who is the
     registered Holder of this Series 1 Bridge
     Note on the date such payment is made.
     (c)  The Company shall pay interest by check
     payable in money of the United States of
     America that at the time of payment is legal
     tender for public and private debts.
     Payments of interest shall be mailed to
     Holder's address shown in the register
     maintained pursuant to Section 2; provided
     however, that with respect to the final
     payment of principal and accrued and unpaid
     interest necessary to pay this Series 1
     Bridge Note in full, to receive such payment
     Holder must surrender this Series 1 Bridge
     Note for cancellation to the Company or to a
     paying agent appointed by the Company.
     Principal and interest shall be considered
     paid on the date due, and no interest shall
     accrue thereafter, if there is on deposit on
     that date, in a bank trust account for the
     benefit of Holder of this Series 1 Bridge
     Note, money sufficient to pay the Redemption
     Price and all accrued and unpaid interest due
     under this Series 1 Bridge Note.

Section 5.     Conversion Price and Adjustments.
     (a)  At anytime after the Maturity Date,
     Holder may convert all or any portion of the
     Redemption Price and accrued and unpaid
     interest due on this Series 1 Bridge Note
     into shares of Common Stock.
     (b)  If Holder elects to convert less than
     the full Redemption Price of this Series 1
     Bridge Note, such conversion shall be
     permitted only in one hundred (100)-share
     increments unless the Company has given its
     contemporaneous consent to conversion of an
     odd lot.  The provisions hereof that apply to
     conversion of the entire Redemption Price of
     this Series 1 Bridge Note shall also apply to
     conversion of a portion of the Redemption
     Price.  Upon surrender of the Series 1 Bridge
     Note for conversion in part, the Company
     shall issue new Series 1 Bridge Notes in
     substantially the same form as this Series 1
     Bridge Note, except that the principal amount
     shall be reduced by the principal amount so
     converted (exclusive of the redemption
     premium).
     (c)  The number of shares of Common Stock
     issuable upon conversion of this Series 1
     Bridge Note is equal to the quotient of the
     Redemption Price of this Series 1 Bridge Note
     being converted divided by Conversion Price.
     Fractional shares will not be issued.  In
     lieu of any fraction of a share, the Company
     shall deliver its check for the dollar amount
     of the less than full share remainder.
     Accrued and unpaid interest shall be included
     in computing the number of Conversion Shares
     issuable upon conversion of this Series 1
     Bridge Note.  Interest shall cease to accrue
     on that portion of the Redemption Price
     converted from and after the Conversion Date.

Section 6.     Procedures for Conversion, and Issuance
of Conversion Shares.
     (a)  Holders' Delivery Requirements.  To
     convert this Series 1 Bridge Note into Common
     Stock, (the "Conversion Date"), the Holder
     hereof shall (A) deliver or transmit by
     facsimile, for receipt on or prior to 11:59
     P.M., Eastern Time, on such date, a copy of a
     fully executed notice of conversion in the
     form attached hereto as Exhibit A (the
     "Conversion Notice") to the Company or its
     designated Transfer Agent, and (B) surrender
     to a common carrier for delivery to the
     Company or the Transfer Agent as soon as
     practicable following such date, the original
     Series 1 Bridge Note being converted (or an
     indemnification undertaking with respect to
     such shares in the case of the loss, theft,
     or destruction of the Series 1 Bridge Note)
     and the originally executed Conversion
     Notice.  The date the Company receives the
     originally executed Conversion Notice and
     this Series 1 Bridge Note is hereinafter the
     "Conversion Date."
     (b)  Company's Response.  Upon receipt by the
     Company of a facsimile copy of a Conversion
     Notice, the Company shall immediately send,
     via Facsimile, a confirmation of receipt of
     such Conversion Notice to Holder.  Upon
     receipt by the Company or the Transfer Agent
     of the Series 1 Bridge Note to be converted
     pursuant to a Conversion Notice, together
     with the originally executed Conversion
     Notice, the Company or the Transfer Agent (as
     applicable) shall, within ten (10) business
     days following the date of receipt, (A) issue
     and surrender to a common carrier for
     overnight delivery to the address as
     specified in the Conversion Notice, a
     certificate, registered in the name of Holder
     or its designee, for the number of shares of
     Common Stock to which Holder shall be
     entitled or (B) credit the aggregate number
     of shares of Common Stock to which such
     Holder shall be entitled to the Holder's or
     its designee's balance account at The
     Depository Trust Company.
     (c)  Record Holder.  The Person or persons
     entitled to receive the shares of Common
     Stock issuable upon a conversion of this
     Series 1 Bridge Note shall be treated for all
     purposes as the "Record Holder" or Holder of
     such shares of Common Stock on the Conversion
     Date.
     (d)  Company's Failure to Timely Convert.  If
     the Company shall fail to issue to Holder
     within ten (10) business days following the
     date of receipt by the Company or the
     Transfer Agent of this Series 1 Bridge Note
     to be converted pursuant to a Conversion
     Notice, a certificate for the number of
     shares of Common Stock to which each Holder
     is entitled upon Holder's conversion of this
     Series 1 Bridge Note, in addition to all
     other available remedies which such Holder
     may pursue hereunder and under the Purchase
     Agreement between the Company and the initial
     Holder of this Series 1 Bridge Note
     (including indemnification pursuant to
     Section 7.18 thereof), the Company shall pay
     additional damages to Holder on each day
     after the tenth (10th) business day following
     the date of receipt by the Company or the
     Transfer Agent an amount equal to 1.0% of the
     product of (A) the number of shares of Common
     Stock not issued to Holder and to which
     Holder is entitled multiplied by (B) the
     Closing Bid Price of the Common Stock on the
     business day following the date of receipt by
     the Company or the Transfer Agent of the
     Conversion Notice.  The foregoing
     notwithstanding, Holder at its option may
     withdraw a Conversion Notice, and remain a
     Holder of this Series 1 Bridge Note, if
     Holder has otherwise complied with this
     Section 6.
     (e)  Adjustments to Conversion Price.  If any
     adjustment to the Conversion Price to be made
     pursuant to Section 7 becomes effective
     immediately after a record date for an event
     as therein described, and conversion occurs
     prior to such event but after the record
     date, the Company may defer issuing,
     delivering, or paying to Holder any
     additional shares of Common Stock or check
     for any cash remainder required by reason of
     such adjustment until the occurrence of such
     event, provided that the Company delivers to
     Holder a due bill or other appropriate
     instrument evidencing the Holders' right to
     receive such additional shares or check upon
     the occurrence of the event giving rise to
     the adjustment.
     (f)  Reservation of Conversion Shares.  Until
     such time as this Series 1 Bridge Note has
     been fully redeemed, the Company shall
     reserve out of its authorized but unissued
     Common Stock enough shares of Common Stock to
     permit the conversion of the entire
     Redemption Price and all accrued and unpaid
     interest due on this Series 1 Bridge Note at
     any time.  All shares of Common Stock issued
     upon conversion of this Series 1 Bridge Note
     shall be fully paid and nonassessable.  The
     Company covenants that if any shares of
     Common Stock, required to be reserved for
     purposes of conversion of this Series 1
     Bridge Note hereunder, require registration
     with or approval of any governmental
     authority under any federal or state law or
     listing upon any national securities exchange
     before such shares may be issued upon
     conversion, the Company shall in good faith,
     as expeditiously as possible, endeavor to
     cause such shares to be duly registered,
     approved or listed, as the case may be.

Section 7.     Adjustments to Conversion Price.

The Conversion Price shall be subject to adjustment
from time to time as follows:
     (a)  If the Company at any time 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 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.
     (b)  Prior to the consummation of any Organic
     Change (as defined below), the Company will
     make appropriate provision (in form and
     substance satisfactory to the Holder to
     insure that Holder will thereafter have the
     right to acquire and receive in lieu of, or
     in addition to, (as the case may be) the
     shares of Common Stock immediately
     theretofore acquirable and receivable upon
     the conversion of this Holder's Series 1
     Bridge Note, such shares of stock,
     securities, or assets as may be issued or
     payable with respect to, or in exchange for,
     the number of shares of Common Stock
     immediately theretofore acquirable and
     receivable upon the conversion of this Series
     1 Bridge Note had such Organic Change not
     taken place.  In any such case, the Company
     will make appropriate provision (in form and
     substance satisfactory to Holder with respect
     to such Holder's rights and interests to
     insure that the provisions of this Section
     7(b) and Sections 6(d) and 6(e) above will
     thereafter be applicable.  The Company will
     not effect any such consolidation, merger, or
     sale, unless prior to the consummation
     thereof the successor entity (if other than
     the Company) resulting from consolidation or
     merger or the entity purchasing such assets
     assumes, by written instrument (in form and
     substance satisfactory to Holder, the
     obligation to deliver to Holder such shares
     of stock, securities, or assets as, in
     accordance with the foregoing provisions,
     that Holder may be entitled to acquire.  For
     purposes of this Agreement, "Organic Change"
     means any recapitalization, reorganization,
     reclassification, consolidation, merger, or
     sale of all or substantially all of the
     Company's assets to another Person (as
     defined below), or other similar transaction

              (i)  The Company defaults in the payment
         of principal and/or interest when the same
         becomes due and payable and such failure is

         the Company receives written demand from
         Holder or the Representative to remedy the
         same.

              (ii) the Company fails to comply with

         $100,000 beyond any period of grace provided
         with respect thereto and the effect of such
         failure is to cause the holder of such Debt

              (iv) any representation or warranty made

         law, whether now or hereafter in effect

         jurisdiction;

              (vii)     the Company petitions or
         applies to any tribunal for, or consents to,
         the appointment of, or taking possession by,
         a trustee, receiver, custodian, liquidation,
         or similar official of the Company, or of any
         substantial part of the assets of the
         Company, or commences a voluntary case under
         the Bankruptcy Law of the United States or
         any proceedings relating to the Company under
         the Bankruptcy Law of any other jurisdiction;

              (viii)    any petition or application
         described in Section 10(a)(vi) above is

         act indicates its approval thereof, consent
         thereto or acquiescence therein, or an order,
         judgment or decree is entered appointing any
         such trustee, receiver, custodian,

         unstayed and in effect for more than sixty
         (60) days;

              (ix) any order, judgment, or decree is
         entered in any proceedings against the
         Company decreeing the dissolution of the
         Company and such order, judgment, or decree
         remains unstayed and in effect for more than
         sixty (60) days; or

              (x)  a final judgment (not fully covered
         by insurance) in an amount in excess of
         $100,000 is rendered against the Company and,
         within ten (10) business days after entry
         thereof, such judgment is not discharged or
         execution thereof stayed pending appeal, or
         within ten (10) days after the expiration of

     (b)  Upon the occurrence of an Event of
     Default described in subsection (vi), (vii),
     or (viii) of Section 10(a), the principal of
     and accrued interest on this Series 1 Bridge
     Note shall automatically become immediately
     due and payable, without presentment, demand,
     protest or other requirements of any kind,
     all of which are hereby expressly waived by
     the Company.  If any other Event of Default
     exists, Holder may, in addition to the
     exercise of any right, power, or remedy
     permitted to Holder by law, declare (by
     written notice or notices to the Company) the
     entire principal of and all interest accrued
     on this Series 1 Bridge Note to be due and
     payable, and this Series 1 Bridge Note shall
     thereupon become immediately due and payable,
     without presentment, demand, protest, or
     other notice of any kind, all of which are
     hereby expressly waived by the Company.  Upon
     such declaration, the Company will
     immediately pay to Holder of this Series 1
     Bridge Note the then outstanding principal of
     and accrued and unpaid interest on the Series
     1 Bridge Notes.  If at any time after
     acceleration of the maturity of the Series 1
     Bridge Notes, the Company shall pay all
     arrears of interest and all payments on
     account of principal which shall have become
     due other than by acceleration (with interest
     on principal and, to the extent permitted by
     law, on overdue interest, at the rate
     specified in the Series 1 Bridge Notes) and
     all Events of Default (other than nonpayment
     of principal of or interest on this Series 1
     Bridge Note due and payable solely by virtue
     of acceleration) shall be remedied or waived
     by Holder by written notice to the Company
     may rescind and annul the acceleration and
     its consequences, but such action shall not
     affect any subsequent Event of Default or
     impair any right consequent thereon.
     (c)  A delay or omission by the Holder of
     this Series 1 Bridge Note in exercising any
     right or remedy arising upon an Event of
     Default shall not impair such right or remedy
     or constitute a waiver of or an acquiescence
     in the Event of Default.
     (d)  If any Event of Default shall occur and
     be continuing, the Holder of this Series 1
     Bridge Note may proceed to protect and
     enforce their rights under this Agreement and
     this Series 1 Bridge Note by exercising such
     remedies as are available to such Holder
     either by suit in equity or by action at law,
     or both, whether for specific performance of
     any covenant or other agreement contained in
     this Agreement or in aid of the exercise of
     any power granted in this Agreement.  No
     remedy conferred in this Agreement upon
     Holder is intended to be exclusive of any
     other remedy, and each and every such remedy
     shall be cumulative and shall be in addition
     to every other remedy conferred herein or now
     or hereafter existing at law or in equity or
     by statute or otherwise.

Cancellation.

     US$5,000.00 upon written request to the
     Company accompanied by surrender of this
     Series 1 Bridge Note to the Company or to an
     agent designated for that purpose.  Any
     Series 1 Bridge Notes issued in exchange for
     this Series 1 Bridge Note shall be one of

     conditions are intended to insure compliance
     with the provisions of the Securities Act of
     1933, as amended (the "Securities Act").
     Prior to any proposed transfer of this Series
     1 Bridge Note the Holder hereof shall give
     written notice to the Company of the proposed
     disposition and shall furnish to the Company
     a statement of the circumstances surrounding
     the proposed disposition and an opinion of
     counsel reasonably satisfactory to the
     Company to the effect that (i) such
     disposition will not require registration of
     such securities under the Securities Act or
     qualification of such securities under the
     blue sky or state securities laws of any
     state in which such qualification would be
     required, or (ii) appropriate action
     necessary for compliance with the Securities
     Act or the blue sky or securities laws of
     such states has been taken. The Holder hereof
     shall cause any proposed transferee of such
     securities to agree to take and hold such
     securities subject to the provisions and upon
     the conditions specified in this Section 11.
     The Company or any co-registrar appointed by
     the Company may require the Holder to furnish
     appropriate endorsements and/or transfer
     documents, including information regarding
     any proposed transferee's name, address and
     social security or taxpayer identification
     number, and to pay any issue or transfer
     taxes or fees as may be required by law.  The
     registered Holder of this Series 1 Bridge
     Note may be treated as its owner for all
     purposes.
     (c)  If Holder claims this Series 1 Bridge
     Note has been lost, destroyed, or wrongfully
     taken, the Company shall issue a replacement
     Series 1 Bridge Note upon (i) receipt of any
     indemnity bond or other assurance requested
     by the Company to protect it from any loss
     which it may suffer by reason of such
     replacement or subsequent presentment of the
     original Series 1 Bridge Note, and
     (ii) payment of any expenses reasonably
     incurred by the Company in replacing the
     Series 1 Bridge Note.

receipt requested, to each Holder at its address shown
in the register kept by the Company or any co-registrar
appointed by the Company and to the Company at the
address of its office to be maintained pursuant to
Section 2.  Failure to mail, or any defect in, a notice
or communication to any other Holder of this Series 1
Bridge Note shall not affect its sufficiency with
respect to the other Holders.  If a notice or
communication is mailed to Holder in the manner
provided above within the time prescribed, it shall be

obligations of the Company under this Series 1 Bridge
Note or for any claim based on, in respect of or by
reason of such obligations or their creation.  The
Holder of this Series 1 Bridge Note by accepting this
Series 1 Bridge Note waives and releases all such
liability and such waiver and release are part of the
consideration for the issue of the Series 1 Bridge
Note.
