Default.  If an Event of Default shall have occurred and shall

        -4-

        
          

        

      

      
        
        

      

       

      payable,
without presentment, demand, protest, or notice, all of which are hereby
expressly unconditionally and irrevocably waived by the Maker; provided,

and payable, and/or (b) exercise or otherwise enforce any one or more of the
Holder’s rights, powers, privileges, remedies and interests under this Note, the

statute or otherwise.  Upon and after an Event of Default of the type
described in Sections 2.1(a), (h) or (i), this Note shall bear interest at the

    CONVERSION;
ANTIDILUTION

     

    Section
3.1                                Conversion
Option.  At any time and from time to time on or after the
Issuance Date (as defined below), this Note shall be convertible (in whole or in
part), at the option of the Holder (the “Conversion Option”),
into such number of fully paid and non-assessable shares of Common Stock (the
“Conversion
Rate”) as is determined by dividing (x) that portion of the outstanding
principal balance plus any accrued but unpaid interest under this Note as of
such date that the Holder elects to convert by (y) the Conversion Price (as
defined in Section 3.2 hereof) then in effect on the date on which the Holder
delivers a notice of conversion (the “Conversion Notice”),
duly executed, to the Company (the “Voluntary Conversion Date”), provided,
however, that the Conversion Price shall be subject to adjustment as described
in Section 3.6 below.  The Holder shall deliver this Note to the
Company at the address designated in the Purchase Agreement at such time that
this Note is fully converted.  With respect to partial conversions of
this Note, the Company shall keep written records of the amount of this Note
converted as of each Conversion Date.

     

    Section
3.2                                Conversion
Price.  The term “Conversion Price” shall mean twenty six cents
($0.26), calculated as the 10 day weighted average closing price of the Maker’s
Common Stock prior to the closing, subject to adjustment under Section 3.6
hereof (the “Set Price”).

     

    
      	
              Section
      3.3

            	
              Mechanics of
      Conversion.

            

    

     

    (a)           Not
later than three (3) Trading Days after any Conversion Date, the Company or its
designated transfer agent, as applicable, shall issue and deliver to the
Depository Trust Company (“DTC”) account on the
Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”) as specified
in the Conversion Notice, registered in the name of the Holder or its
affiliates, for the number of shares of Common Stock to which the Holder shall
be entitled.  In the alternative, not later than three (3) Trading
Days after any Conversion Date, the Company or its designated transfer agent, as
applicable, shall deliver to the applicable Holder by express courier a
certificate or certificates which shall be free of restrictive legends and
trading restrictions (other than those required by Section 5.1 of the Purchase
Agreement)

     

    
      
        
        

      

      
        -5-

        
          

        

      

      
        
        

      

       

      representing
the number of shares of Common Stock being acquired upon the conversion of this
Note (the “Delivery
Date”).  Notwithstanding the foregoing to the contrary, the
Company or its transfer agent shall only be obligated to issue and deliver the
shares to the DTC on the Holder’s behalf via DWAC (or certificates free of
restrictive legends) if such conversion is in connection with a sale and the
Holder has complied with the applicable prospectus delivery requirements (as
evidenced by documentation furnished to and reasonably satisfactory to the
Company) or such shares may be sold pursuant to Rule 144 or other exemption
under the Securities Act.  If in the case of any Conversion Notice
such certificate or certificates are not delivered to or as directed by the
applicable Holder by the Delivery Date, the Holder shall be entitled by written
notice to the Company at any time on or before its receipt of such certificate
or certificates thereafter, to rescind such conversion, in which event the
Company shall immediately return this Note tendered for conversion, whereupon
the Company and the Holder shall each be restored to their respective positions
immediately prior to the delivery of such notice of revocation, except that any
amounts described in Sections 3.3(b) and (c) shall be payable through the date
notice of rescission is given to the Company.

    

     

    (b)           The
Company understands that a delay in the delivery of the shares of Common Stock
upon conversion of this Note beyond the Delivery Date could result in economic
loss to the Holder.  If the Company fails to deliver to the Holder
such shares via DWAC (or, if applicable, certificates) by the Delivery Date, the
Company shall pay to such Holder, in cash, an amount per Trading Day for each
Trading Day until such shares are delivered via DWAC or certificates are
delivered (if applicable), together with interest on such amount at a rate of
10% per annum, accruing until such amount and any accrued interest thereon is
paid in full, equal to the greater of (A) 2% of the aggregate principal amount
of the Notes requested to be converted for each Trading Day and (B) $2,000 per
day (which amount shall be paid as liquidated damages and not as a
penalty).  Nothing herein shall limit a Holder’s right to pursue
actual damages for the Company’s failure to deliver certificates representing
shares of Common Stock upon conversion within the period specified herein and
such Holder shall have the right to pursue all remedies available to it at law
or in equity (including, without limitation, a decree of specific performance
and/or injunctive relief).  Notwithstanding anything to the contrary
contained herein, the Holder shall be entitled to withdraw a Conversion Notice,
and upon such withdrawal the Company shall only be obligated to pay the
liquidated damages accrued in accordance with this Section 3.3(b) through the
date the Conversion Notice is withdrawn.

     

    (c)           In
addition to any other rights available to the Holder, if the Company fails to
cause its transfer agent to transmit via DWAC or transmit to the Holder a
certificate or certificates representing the shares of Common Stock issuable
upon conversion of this Note (the “Conversion Shares”)
on or before the Delivery Date, and if after such date the Holder is required by
its broker to purchase (in an open market transaction or otherwise) shares of
Common Stock to deliver in satisfaction of a sale by the Holder of the shares of
Common Stock issuable upon conversion of this Note which the Holder anticipated
receiving upon such conversion (a “Buy-In”), then the
Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Common Stock issuable upon conversion of this Note that the
Company was

     

    
      
        
        

      

      
        -6-

        
          

        

      

      
        
        

      

       

      required
to deliver to the Holder in connection with the conversion at issue times (B)
the price at which the sell order giving rise to such purchase obligation was
executed, and (2) at the option of the Holder, either reinstate the portion of
the Note and equivalent number of shares of Common Stock for which such
conversion was not honored or deliver to the Holder the number of shares of
Common Stock that would have been issued had the Company timely complied with
its conversion and delivery obligations hereunder.  For example, if
the Holder purchases Common Stock having a total purchase price of $11,000 to
cover a Buy-In with respect to an attempted conversion of shares of Common Stock
with an aggregate sale price giving rise to such purchase obligation of $10,000,
under clause (1) of the immediately preceding sentence the Company shall be
required to pay the Holder $1,000. The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In,
together with applicable confirmations and other evidence reasonably requested
by the Company.  Nothing herein shall limit a Holder’s right to pursue
any other remedies available to it hereunder, at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief
with respect to the Company’s failure to timely deliver certificates
representing shares of Common Stock upon conversion of this Note as required
pursuant to the terms hereof.

    

     

    Section
3.4                                Ownership Cap and Certain
Conversion Restrictions. Notwithstanding anything to the contrary set
forth in Section 3 of this Note, at no time may the Holder convert all or a
portion of this Note if the number of shares of Common Stock to be issued
pursuant to such conversion, when aggregated with all other shares of Common
Stock owned by the Holder at such time, would result in the Holder beneficially
owning (as determined in accordance with Section 13(d) of the Exchange Act and
the rules thereunder) in excess of 4.99% of the then issued and outstanding
shares of Common Stock outstanding at such time; provided, however, that upon
the Holder providing the Company with 61 days’ prior written notice that the
Holder would like to waive Section 3.4 of this Note with regard to any or all
shares of Common Stock issuable upon conversion of this Note, this Section 3.4
shall be of no force or effect with regard to all or a portion of the Note
referenced in the waiver notice.

     

    Section
3.5                                Trading 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 in the aggregate without breaching the Company’s
obligations under the rules or regulations of any applicable Trading Market,
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 Trading 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
Holder.

    Section
3.6                                Adjustment of Conversion
Price.

     

    (a)           Until
the Note has been paid in full or converted in full, the Set Price shall be
subject to adjustment from time to time as follows (but shall not be increased,
other than pursuant to Section 3.6(a)(i) hereof):

     

    (i)           Adjustment for Stock
Dividends, Subdivisions and Combinations.  If at any time the
Company shall:

     

    

    (1)           set
a record date or take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, shares of Common Stock,

     

    (2)           subdivide
its outstanding shares of Common Stock into a larger number of shares of Common
Stock, or

     

    (3)           combine
its outstanding shares of Common Stock into a smaller number of shares of Common
Stock,

     

    then (1)
the number of Conversion Shares immediately after the occurrence of any such
event shall be adjusted to equal the number of shares of Common Stock which a
record holder of the same number of shares of Common Stock for which this Note
may be converted immediately prior to the occurrence of such event would own or
be entitled to receive after the happening of such event (without giving effect
to the limitations on exercise set forth in Section 3.4 hereof), and (2) the Set
Price then in effect shall be adjusted to equal (A) the Set Price then in effect
multiplied by the number of shares of Common Stock for which this Note may be
converted immediately prior to the adjustment (without giving effect to the
limitations on exercise set forth in Section 3.4 hereof) divided by (B) the
number of shares of Common Stock for which this Note may be converted
immediately after such adjustment (without giving effect to the limitations on
exercise set forth in Section 3.4 hereof).

     

    (ii)           Adjustment upon Issuance of
shares of Common Stock.  If at any time the Company issues or
sells, or in accordance with this Section 3.6(a)(ii) 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 for a
consideration per share (the "New Issuance Price")
less than a price (the "Applicable Price")
equal to the Set 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 Set Price then in effect
shall be reduced to an amount equal to the New Issuance Price.  Upon
each such adjustment of the Set Price hereunder, the number of Conversion Shares
shall be adjusted to the number of shares of Common Stock determined by
multiplying the Set Price in effect immediately prior to such adjustment by the
number of Conversion Shares acquirable upon conversion of this Note immediately
prior to such adjustment and dividing the product thereof by the Set Price
resulting from such adjustment.  For purposes of determining the
adjusted Set Price under this Section 3.6, the following shall be
applicable:

     

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

     

    (1)           Issuance of
Options.  If the Company in any manner grants any options to
purchase Common Stock (“Options”), other than
Options granted to employees and consultants pursuant to any employee stock
benefit, option, purchase or similar plan approved by the Company’s Board of
Directors, 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, exercise or
exchange of any stock or securities (other than Options) directly or indirectly
convertible into or exercisable or exchangeable for shares of Common Stock
(“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 3.6(a)(ii)(1), the "lowest price per share for which
one share of Common Stock is issuable upon exercise of such Options or upon
conversion, exercise or exchange of such Convertible Securities issuable upon
exercise of any 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 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 Set Price or number of Conversion 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.

     

    (2)           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 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 3.6(a)(ii)(2), the "lowest
price per share for which one share of Common Stock is issuable upon the
conversion, exercise or exchange thereof" 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 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 Set Price or
number of Conversion 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 Note has been or is to
be made pursuant to other provisions of this Section 3.6, no further adjustment
of the Set Price or number of Conversion Shares shall be made by reason of such
issue or sale.

     

    (3)           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
Set Price and the number

     

    
      
        
        

      

      
        -9-

        
          

        

      

      
        
        

      

       

      of
Conversion Shares in effect at the time of such increase or decrease shall be
adjusted to the Set Price and the number of shares of Common Stock issuable upon
conversion of this Note 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 3.6(a)(ii)(3), if the terms of any
Option or Convertible Security that was outstanding as of the date of issuance
of this Note 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 3.6(a)(ii)(3) shall
be made if such adjustment would result in an increase of the Set Price then in
effect or a decrease in the number of Conversion Shares.

    

     

    (4)           Calculation of Consideration
Received.  In case any Option 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
Options by the parties thereto, the Options 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 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 securities
will be determined jointly by the Company and the Holder.  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 Holder.  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.

     

    (iii)           Certain Other
Distributions.  If at any time the Company shall set a record
date or take a record of the holders of its Common Stock for the purpose of
entitling them to receive any divi­dend or other distribution
of:

     

    (1)           cash
(other than a cash dividend payable out of earnings or earned surplus legally
available for the payment of dividends under the laws of the jurisdiction of
incorporation of the Company),

     

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

     

    (2)           any
evidences of its indebtedness, any shares of stock of any class or any other
securities or property of any nature whatsoever (other than cash or Common
Stock), or

     

    (3)           any
warrants or other rights to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property of any nature whatsoever (other than cash or Common
Stock),

     

    then (1)
the number of Conversion Shares may shall be adjusted to equal the product of
the number of shares of Common Stock for which this Note may be converted
immediately prior to such adjustment (without giving effect to the limitations
on exercise set forth in Section 3.4 hereof) multiplied by a fraction (A) the
numerator of which shall be the Closing Bid Price of Common Stock at the date of
taking such record and (B) the denominator of which shall be such Closing Bid
Price minus the amount allocable to one share of Common Stock of any such cash
so distributable and of the fair value (as determined in good faith by the Board
of Directors of the Company and supported by an opinion from an investment
banking firm reasonably acceptable to the Holder) of any and all such evidences
of indebtedness, shares of stock, other securities or property or warrants or
other subscription or purchase rights so distributable, and (2) the Set Price
then in effect shall be adjusted to equal (A) the Set Price then in effect
multiplied by the number of shares of Common Stock for which this Note may be
converted immediately prior to the adjustment (without giving effect to the
limitations on exercise set forth in Section 3.4 hereof) divided by (B) the
number of shares of Common Stock for which this Note may be converted
immediately after such adjustment (without giving effect to the limitations on
exercise set forth in Section 3.4 hereof).  A reclassification of the
Common Stock (other than a change in par value, or from par value to no par
value or from no par value to par value) into shares of Common Stock and shares
of any other class of stock shall be deemed a distribution by the Company to the
holders of its Common Stock of such shares of such other class of stock within
the meaning of this Section 3.6(a) and, if the outstanding shares of Common
Stock shall be changed into a larger or smaller number of shares of Common Stock
as a part of such reclassification, such change shall be deemed a subdivision or
combination, as the case may be, of the outstanding shares of Common Stock
within the meaning of Section 3.6(a).

    

    (b)           Other Provisions applicable
to Adjustments under this Section.  The following provisions
shall be applicable to the making of adjustments of the number of shares of
Common Stock for which this Note may be converted and the Set Price then in
effect provided for in this Section 3.6:

     

    (i)           Fractional
Interests.  In computing adjustments under this
Section 3.6, fractional interests in Common Stock shall be taken into
account to the nearest one one-hundredth (1/100th) of a
share.

     

    (ii)           When Adjustment Not
Required.  If the Company shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive a dividend or
distribution or subscription or purchase rights and shall, thereafter and before
the distribution to stockholders thereof, legally abandon its plan to pay or
deliver such dividend, distribution, subscription or purchase rights, then
thereafter no adjustment shall be required by reason of the

     

    
      
        
        

      

      
        -11-

        
          

        

      

      
        
        

      

       

      taking of
such record and any such adjustment previously made in respect thereof shall be
rescinded and annulled.

    

     

    (c)           Form of Note after
Adjustments.  The form of this Note need not be changed because
of any adjustments in the Set Price or the number and kind of securities
purchasable upon conversion of this Note.

     

    (d)           Escrow of
Property.  If after any property becomes distributable pursuant
to this Section 3.6 by reason of the taking of any record of the holders of
Common Stock, but prior to the occurrence of the event for which such record is
taken, and the Holder converts this Note, such property shall be held in escrow
for the Holder by the Company to be distributed to the Holder upon and to the
extent that the event actually takes place, upon payment of the then current Set
Price.  Notwithstanding any other provision to the contrary herein, if
the event for which such record was taken fails to occur or is rescinded, then
such escrowed property shall be returned to the Company.

     

    (e)           No
Impairment.  The Company shall not, by amendment of its
Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, 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 to be observed or performed hereunder by the Company, but will at all
times in good faith, assist in the carrying out of all the provisions of this
Section 3.6 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the Holder against
impairment.  In the event the Holder shall elect to convert the Note
as provided herein, the Company cannot refuse conversion based on any claim that
the Holder or any one associated or affiliated with the Holder has been engaged
in any violation of law, violation of an agreement to which the Holder is a
party or for any reason whatsoever, unless, an injunction from a court, or
notice, restraining and or adjoining conversion of the Note shall have issued
and the Company posts a surety bond for the benefit of the Holder in an amount
equal to one hundred fifty percent (150%) of the amount of the Notes, which bond
shall remain in effect until the completion of arbitration/litigation of the
dispute and the proceeds of which shall be payable to the Holder (as liquidated
damages) in the event it obtains judgment.

     

    (f)           Certificates as to
Adjustments.  Upon occurrence of each adjustment or
readjustment of the Conversion Price or number of shares of Common Stock
issuable upon conversion of this Note pursuant to this Section 3.6, the Company
at its expense shall promptly compute such adjustment or readjustment in
accordance with the terms hereof and furnish to the Holder a certificate setting
forth such adjustment and readjustment, showing in detail the facts upon which
such adjustment or readjustment is based.  The Company shall, upon
written request of the Holder, at any time, furnish or cause to be furnished to
the Holder a like certificate setting forth such adjustments and readjustments,
the applicable Conversion Price in effect at the time, and the number of shares
of Common Stock and the amount, if any, of other securities or property which at
the time would be received upon the conversion of this
Note.  Notwithstanding the foregoing, the Company shall not be
obligated to deliver a certificate unless such certificate would reflect an
increase or decrease of at least one percent (1%) of such adjusted
amount.

     

    
      
        
        

      

      
        -12-

        
          

        

      

      
        
        

      

    

     

    (f)           Issue
Taxes.  The Company shall pay any and all issue and other
taxes, excluding federal, state or local income taxes, that may be payable in
respect of any issue or delivery of shares of Common Stock on conversion of this
Note pursuant thereto; provided, however, that the
Company shall not be obligated to pay any transfer taxes resulting from any
transfer requested by the Holder in connection with any such
conversion.

     

    (g)           Fractional
Shares.  No fractional shares of Common Stock shall be issued
upon conversion of this Note.  In lieu of any fractional shares to
which the Holder would otherwise be entitled, the Company shall pay cash equal
to the product of such fraction multiplied by the average of the Closing Bid
Prices of the Common Stock for the five (5) consecutive Trading Days immediately
preceding the Conversion Date.

     

    (h)           Reservation of Common
Stock.  The Company shall at all times when this Note shall be
outstanding, reserve and keep available out of its authorized but unissued
Common Stock, such number of shares of Common Stock as shall from time to time
be sufficient to effect the conversion of this Note and all interest accrued
thereon; provided that the
number of shares of Common Stock so reserved shall at no time be less than one
hundred fifty percent (150%) of the number of shares of Common Stock for which
this Note and all interest accrued thereon are at any time
convertible.  The Company shall, from time to time in accordance with
Delaware law, increase the authorized number of shares of Common Stock if at any
time the unissued number of authorized shares shall not be sufficient to satisfy
the Company’s obligations under this Section 3.6(h).

     

    (i)           ­Regulatory
Compliance.  If any shares of Common Stock to be reserved for
the purpose of conversion of this Note or any interest accrued thereon require
registration or listing with or approval of any governmental authority, stock
exchange or other regulatory body under any federal or state law or regulation
or otherwise before such shares may be validly issued or delivered upon
conversion, the Company shall, at its sole cost and expense, in good faith and
as expeditiously as possible, endeavor to secure such registration, listing or
approval, as the case may be.

    PREPAYMENT

     

    Section
4.1                                Prepayment.

     

    (a)           Prepayment Option Upon Major
Transaction.  In addition to all other rights of the Holder
contained herein, simultaneous with the occurrence of a Major Transaction (as
defined below), the Holder shall have the right, at the Holder’s option, to
require the Maker to prepay the Note in cash at a price equal to the sum of (i)
one hundred percent (100%) of the aggregate principal amount of this Note plus
all accrued and unpaid interest (if any), and (ii) all other fees, costs,
expenses, liquidated damages or other amounts (if any) owing in respect of this
Note and the other Transaction Documents (the “Major Transaction Prepayment
Price”); provided, however, in the case of a Major Transaction described in
Section 4.1(b)(iv) below, the Major Transaction Prepayment Price shall be equal
to the lesser of (x) the amount described in

      clauses
(i) and (ii) of this Section 4.1(a) or (y) 100% of the aggregate amount of cash
received (directly or indirectly) from time to time (whether as initial
consideration or through the payment or disposition of deferred consideration)
by or on behalf of Maker in connection with such Major Transaction after
deducting therefrom only reasonable fees, commissions, and expenses related
thereto and required to be paid by the Maker in connection with such Major
Transaction to the extent, but only to the extent, that the amounts so deducted
are, at the time of receipt of such cash, actually paid or payable to a Person
that is not an affiliate of Maker and are properly attributable to such Major
Transaction (the “Net Cash Proceeds”).

    

     

    (b)           “Major
Transaction.”  A “Major Transaction” shall be deemed to have
occurred at such time as any of the following events:

     

    (i)           the
consolidation, merger or other business combination of the Maker with or into
another Person (other than (A) pursuant to a migratory merger effected solely
for the purpose of changing the jurisdiction of incorporation of the Maker or
(B) a consolidation, merger or other business combination in which holders of
the Maker’s voting power immediately prior to the transaction continue after the
transaction to hold, directly or indirectly, the voting power of the surviving
entity or entities necessary to elect a majority of the members of the board of
directors (or their equivalent if other than a corporation) of such entity or
entities);

     

    (ii)           the
sale or transfer of more than fifty percent (50%) of the Maker’s assets (based
on the fair market value as determined in good faith by the Maker’s Board of
Directors) other than inventory in the ordinary course of business in one or a
related series of transactions;

     

    (iii)           closing
of a purchase, tender or exchange offer made to the holders of more than fifty
percent (50%) of the outstanding shares of Common Stock in which more than fifty
percent (50%) of the outstanding shares of Common Stock were tendered and
accepted; or

     

    (iv)           the
issuance by the Maker in one or more related or unrelated transactions of any
shares, Options (other than Options granted to employees and consultants
pursuant to any employee stock benefit, option, purchase or similar plan
approved by the Company’s Board of Directors), warrants (other than the
Warrants), interests, participations, or other equivalents (regardless of how
designated) of the Maker, whether voting or nonvoting, including Common Stock,
preferred stock or any other “equity security” (as such term is defined in Rule
3a11-1 of the General Rules and Regulations promulgated by the Commission under
the Exchange Act) or any equity contribution in received by the Company, which
in the aggregate results in Net Cash Proceeds in excess of
$500,000.

     

    (c)           Mechanics of Prepayment at
Option of Holder Upon Major Transaction.  No sooner than
fifteen (15) days nor later than ten (10) days prior to the consummation of a
Major Transaction, but not prior to the public announcement of such Major
Transaction, the Maker shall deliver written notice thereof via facsimile and
overnight courier (“Notice of Major Transaction”) to the Holder of this
Note.  At any time after receipt of a Notice of Major Transaction (or,
in the event a Notice of Major Transaction is not delivered at least ten (10)
days prior to a Major Transaction, at any time within ten (10) days prior to a
Major Transaction), the

     

    
      
        
        

      

      
        -14-

        
          

        

      

      
        
        

      

       

      Holder of
this Note may require the Maker to prepay, effective immediately prior to the
consummation of such Major Transaction, the Note by delivering written notice
thereof via facsimile and overnight courier (“Notice of Prepayment at Option of
the Holder Upon Major Transaction”) to the Maker, which Notice of Prepayment at
Option of Holder Upon Major Transaction shall indicate the applicable Major
Transaction Prepayment Price, as calculated pursuant to Section 4.1(a)
above.

    

     

    (d)           Payment of Prepayment
Price.  Upon the Maker’s receipt of a Notice(s) of Prepayment
at Option of Holder Upon Major Transaction from the Holder of this Note, the
Maker shall immediately notify the Holder of this Note by facsimile of the
Maker’s receipt of such Notice(s) of Prepayment at Option of Holder Upon Major
Transaction and the Maker shall deliver the Major Transaction Prepayment Price
immediately prior to or contemporaneous with the consummation of the Major
Transaction.  If the Maker shall fail to prepay the Note submitted for
prepayment (other than pursuant to a dispute as to the arithmetic calculation of
the Prepayment Price) immediately prior to or contemporaneous with the
consummation of the Major Transaction, in addition to any remedy the Holder of
this Note may have under this Note and the Purchase Agreement, the Major
Transaction Prepayment Price payable in respect of the Note not prepaid shall
bear interest at the rate of two and one half percent (2.5%) per month (prorated
for partial months) until paid in full.

right to pursue actual damages for any failure by the Maker 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 thereof and shall not, except as
expressly provided herein, be subject to any other obligation of the Maker (or
the performance thereof).  The Maker acknowledges that a breach by it
of its obligations hereunder will cause irreparable and material harm to the
Holder and that the remedy at law for any such breach may be inadequate.
Therefore the Maker agrees that, in the event of any such breach or threatened
breach, the Holder shall be entitled, in addition to all other available rights
and remedies, at law or in equity, to seek and obtain such equitable relief,
including but not limited to an injunction restraining any such breach or
threatened breach, without the necessity of showing economic loss and without
any bond or other security being required.

    

     

    Section
5.5                                Enforcement
Expenses.  The Maker agrees to pay all costs and expenses
incurred from time to time by the Holder with respect to any modification,
consent or waiver of the provisions of this Note or the Transaction Documents
and any enforcement of this Note and the Transaction Documents, including,
without limitation, reasonable attorneys’ fees and expenses.

    (a)           This
Note may not be modified or amended in any manner except in writing executed by
the Maker and the Holder.

     

    (b)           To
the extent that amendments to this Note are required in connection with the
filing of a listing application with the American Stock Exchange in connection
with the transactions contemplated hereby, the Maker and the Holder shall
cooperate in good faith to reach mutually acceptable resolutions with regard to
such amendments, without penalty; provided that the Holder has, in its sole
discretion, determined such amendments to be advisable.

     

    Section
5.7                                Compliance with Securities
Laws.

     

    (a)           The
Holder of this Note acknowledges that this Note is being acquired solely for the
Holder’s own account and not as a nominee for any other party, and for
investment, and that the Holder shall not offer, sell or otherwise dispose of
this Note except in accordance with applicable law.

     

    (b)           The
Holder is an “accredited investor” (as defined in Rule 501 of Regulation D under
the Securities Act), and such Holder has such experience in business and
financial matters that it is capable of evaluating the merits and risks of an
investment in the Securities.  The Holder is not required to be
registered as a broker-dealer under Section 15 of the Exchange Act and it is not
a broker-dealer.  The Holder acknowledges that an investment in the
Securities is speculative and involves a high degree of risk.

    Section
5.8                                Consent to

irrevocably submits to the exclusive jurisdiction of the United States District
Court sitting in the Southern District of New York and the courts of the State
of New York located in New York county for the purposes of any suit, action or
proceeding arising out of or relating to this Note and (ii) hereby waives, and
agrees not to assert in any such suit, action or proceeding, any claim that it

Holder consents to process being served in any such suit, action or proceeding
by mailing a copy thereof to such party 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

manner permitted by law.

    Section
5.10                                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.

     

    Section
5.11                                Maker Waivers; Dispute
Resolution.

hereby waive presentment, demand, notice of nonpayment, protest and all other
demands’ and notices in connection with the delivery, acceptance, performance

extensions of the time or payment hereof and agree that any such renewals or
extensions may be made without notice to any such persons and without affecting
their liability herein and do further consent to the release of any person
liable hereon, all without affecting the liability of the other persons, firms
or Maker liable for the payment of this Note, AND DO HEREBY WAIVE TRIAL BY
JURY.

delay or omission on the part of the Holder in exercising its rights under this

    FOR VALUE
RECEIVED, subject to the provisions hereinafter set forth, the undersigned,
Implant Sciences Corporation., a Massachusetts corporation (together with its
successors and assigns, the “Issuer”), hereby
certifies that DMRJ Group LLC or its registered assigns is entitled to
subscribe for and purchase, during the period specified in this Warrant, up to
One Million (1,000,000) shares (subject to adjustment as hereinafter provided)
of the duly authorized, validly issued, fully paid and non-assessable Common
Stock of the Issuer, at an exercise price per share equal to the Warrant Price
then in effect, subject, however, to the provisions and upon the terms and
conditions hereinafter set forth.  Capitalized terms used in this
Warrant and not otherwise defined herein shall have the respective meanings
specified in Section 9 hereof.

    

    1.           Term.  The
right to subscribe for and purchase shares of Warrant Stock represented hereby
shall commence on December 10, 2008 and shall expire at 5:00 p.m., eastern time,
on December 10, 2013 (such period being the “Term”).

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    
      	
               
      

            	
              2.

            	
              Method of Exercise

      Exchange.

            

    

    

    (a)           Time of
Exercise.  The purchase rights represented by this Warrant may
be exercised in whole or in part at any time and from time to time during the
Term commencing on December 10, 2008.

    

    (b)           Method of
Exercise.  The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder’s election (i) by certified or official bank
check or by wire transfer to an account designated by the Issuer, (ii) by
“cashless exercise” in accordance with the provisions of subsection (c) of this
Section 2, or (iii) by a combination of the foregoing methods of payment
selected by the Holder of this Warrant.

    

    (c)           Cashless
Exercise.  Notwithstanding any provisions herein to the
contrary, if the Per Share Market Value of one share of Common Stock is greater
than the Warrant Price (at the date of calculation as set forth below), in lieu
of exercising this Warrant by payment of cash, the Holder may exercise this
Warrant by a cashless exercise and shall receive the number of shares of Common
Stock equal to an amount (as determined below) by surrender of this Warrant at
the principal office of the Issuer together with the properly endorsed Notice of
Exercise in which event the Issuer shall issue to the Holder a number of shares
of Common Stock computed using the following formula:

    

    X = Y - (A)(Y)

                     B

    

    
      	
              Where

            	
              X
      =

            	
              the
      number of shares of Common Stock to be issued to the
    Holder.

            

    

    

    
      	
               
      

            	
              Y
      =

            	
              the
      number of shares of Common Stock purchasable upon exercise of all of the
      Warrant or, if only a portion of the Warrant is being exercised, the
      portion of the Warrant being
exercised.

            

    

    

    
      	
               
      

            	
              A
      =

            	
              the
      Warrant Price.

            

    

    

    B
=           the Per Share
Market Value of one share of Common Stock.

    

    Notwithstanding
anything herein to the contrary, on the last day of the Term, this Warrant shall
be automatically exercised via cashless exercise pursuant to this Section
2(c).

    

    (d)           Issuance of Stock
Certificates.  In the event of any exercise of the rights
represented by this Warrant in accordance with and subject to the terms and
conditions hereof, (i) certificates for the shares of Warrant Stock so purchased
shall be dated the date of such exercise and delivered to the Holder hereof
within a reasonable time, not exceeding three (3) Trading Days after such
exercise (the “Delivery Date”) or,
if the Issuer’s Securities are eligible for such

      manner of
delivery, then at the request of the Holder, issued and delivered to the
Depository Trust Company (“DTC”) account on the
Holder’s behalf via the Deposit Withdrawal Agent Commission System (“DWAC”), within a
reasonable time, not exceeding three (3) Trading Days after such exercise, and
the Holder hereof shall be deemed for all purposes to be the Holder of the
shares of Warrant Stock so purchased as of the date of such exercise and (ii)
unless this Warrant has expired, a new Warrant representing the number of shares
of Warrant Stock, if any, with respect to which this Warrant shall not then have
been exercised (less any amount thereof which shall have been canceled in
payment or partial payment of the Warrant Price as hereinabove provided) shall
also be issued to the Holder hereof at the Issuer’s expense within such
time.

    

    

    (e)           Transferability of
Warrant.  Subject to Section 2(g), this Warrant may be
transferred, in whole or in part, by a Holder without the consent of the
Issuer.  If transferred pursuant to this paragraph, this Warrant may
be transferred on the books of the Issuer by the Holder hereof in person or by
the Holder’s duly authorized attorney, upon surrender of this Warrant at the
principal office of the Issuer, properly endorsed (by the Holder executing an
assignment in the form attached hereto) and upon payment of any necessary
transfer tax or other governmental charge imposed upon such
transfer.  This Warrant is exchangeable at the principal office of the
Issuer for Warrants for the purchase of the same aggregate number of shares of
Warrant Stock, each new Warrant to represent the right to purchase such number
of shares of Warrant Stock as the Holder hereof shall designate at the time of
such exchange.  All Warrants issued on transfers or exchanges shall be
dated the Original Issue Date and shall be identical with this Warrant except as
to the number of shares of Warrant Stock issuable pursuant thereto.

    

    (f)           Continuing Rights of
Holder.  The Issuer will, at the time of or at any time after
each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant, provided that if any
such Holder shall fail to make any such request, the failure shall not affect
the continuing obligation of the Issuer to afford such rights to such
Holder.

    

    (g)           Compliance with Securities
Laws.

    

    (i)           The
Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and
the shares of Warrant Stock to be issued upon exercise hereof are being acquired
solely for the Holder’s own account and not as a nominee for any other party,
and for investment, and that the Holder will not offer, sell or otherwise
dispose of this Warrant or any shares of Warrant Stock to be issued upon
exercise hereof except pursuant to an effective registration statement, or an
exemption from registration, under the Securities Act and any applicable state
securities laws.

    

    (ii)           Except
as provided in paragraph (iii) below, this Warrant and all certificates
representing shares of Warrant Stock issued upon exercise hereof shall be
stamped or imprinted with a legend in substantially the following
form:

     

    
      
        
        

      

      
        -3-

        
          

        

      

      
        
        

      

    

    

    THIS
WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE
STATE SECURITIES LAWS OR IMPLANT SCIENCES CORPORATION SHALL HAVE RECEIVED AN
OPINION OF COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT
AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT
REQUIRED.

    

    (iii)           The
restrictions imposed by this subsection (g) upon the transfer of this Warrant or
the shares of Warrant Stock to be purchased upon exercise hereof shall terminate
(A) when such securities shall have been resold pursuant to an effective
registration statement under the Securities Act, (B) upon the Issuer’s receipt
of an opinion of counsel, in form and substance reasonably satisfactory to the
Issuer, addressed to the Issuer to the effect that such restrictions are no
longer required to ensure compliance with the Securities Act and state
securities laws, or (C) upon the Issuer’s receipt of other evidence reasonably
satisfactory to the Issuer that such registration and qualification under the
Securities Act and state securities laws are not required. Whenever such
restrictions shall cease and terminate as to any such securities, the Holder
thereof shall be entitled to receive from the Issuer (or its transfer agent and
registrar), without expense (other than applicable transfer taxes, if any), new
Warrants (or, in the case of shares of Warrant Stock, new stock certificates) of
like tenor not bearing the applicable legend required by paragraph (ii) above
relating to the Securities Act and state securities laws.

    

    (h)           Buy In.

    

    In addition to any other rights
available to the Holder, if the Issuer fails to cause its transfer agent to
transmit to the Holder  a certificate or certificates representing the
Warrant Stock pursuant to an exercise on or before the Delivery Date (or, in the
case of any exercise of this Warrant after the six month anniversary of the
Original Issue Date, any such certificate representing Warrant Stock contains
any legend restricting transfer (including any legend set forth in Section
2(g)(ii) above)), and if after such date the Holder is required by its broker to
purchase (in an open market transaction or otherwise) shares of Common Stock to
deliver in satisfaction of a sale by the Holder of the Warrant Stock which the
Holder anticipated receiving upon such exercise (a “Buy-In”), then the
Issuer shall (1) pay in cash to the Holder the amount by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Warrant Stock that the Issuer was required to deliver to the
Holder in connection with the exercise at issue times, (B) the price at which
the sell order giving rise to such purchase obligation was executed, and (2) at
the option of the Holder, either reinstate the

     

    
      
        
        

      

      
        -4-

        
          

        

      

      
        
        

      

       

      portion
of the Warrant and equivalent number of shares of Warrant Stock for which such
exercise was not honored or deliver to the Holder the number of shares of Common
Stock that would have been issued had the Issuer timely complied with its
exercise and delivery obligations hereunder.  For example, if the
Holder purchases Common Stock having a total purchase price of $11,000 to cover
a Buy-In with respect to an attempted exercise of shares of Common Stock with an
aggregate sale price giving rise to such purchase obligation of $10,000, under
clause (1) of the immediately preceding sentence the Issuer shall be required to
pay the Holder $1,000.  The Holder shall provide the Issuer written
notice indicating the amounts payable to the Holder in respect of the Buy-In,
together with applicable confirmations and other evidence reasonably requested
by the Issuer.  Nothing herein shall limit a Holder’s right to pursue
any other remedies available to it hereunder, at law or in equity including,
without limitation, a decree of specific performance and/or injunctive relief
with respect to the Issuer’s failure to timely deliver certificates representing
shares of Common Stock upon exercise of this Warrant as required pursuant to the
terms hereof.

    

    

    3.           Stock Fully Paid;
Reservation and Listing of Shares; Covenants.

    

    (a)           Stock Fully
Paid.  The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through Issuer.  The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a number of shares of Common Stock equal to at least
150% of the aggregate number of shares of Common Stock exercisable hereunder to
provide for the exercise of this Warrant (without regard to limitations on
exercisability set forth in Section 8).

    

    (b)           Reservation.  If
any shares of Common Stock required to be reserved for issuance upon exercise of
this Warrant or as otherwise provided hereunder require registration or
qualification with any governmental authority under any federal or state law
before such shares may be so issued, the Issuer will in good faith use its best
efforts as expeditiously as possible at its expense to cause such shares to be
duly registered or qualified.  If the Issuer shall list any shares of
Common Stock on any securities exchange or market it will, at its expense, list
thereon, maintain and increase when necessary such listing, of, all shares of
Warrant Stock from time to time issued upon exercise of this Warrant or as
otherwise provided hereunder, and, to the extent permissible under the
applicable securities exchange’s rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed.  The Issuer will also so list on each securities
exchange or market, and will maintain such listing of, any other securities
which the Holder of this Warrant shall be entitled to receive upon the exercise
of this Warrant if at the time any securities of the same class shall be listed
on such securities exchange or market by the Issuer.

    

    (c)           Covenants.  The
Issuer shall not by any action including, without limitation, amending the
Articles of Organization or the by-laws of the Issuer, or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other action, avoid or seek to avoid the observance or
performance of any of the terms of this

     

    
      
        
        

      

      
        -5-

        
          

        

      

      
        
        

      

       

      Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment.  Without limiting the
generality of the foregoing, the Issuer will (i) not increase the par value of
its Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate Articles of Organization or by-laws of
the Issuer in any manner that would adversely affect the rights of the Holders
of the Warrants, (iii) take all such action as may be reasonably necessary in
order that the Issuer may validly and legally issue fully paid and nonassessable
shares of Common Stock, free and clear of any liens, claims, encumbrances and
restrictions (other than as provided herein) upon the exercise of this Warrant,
and (iv) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
reasonably necessary to enable the Issuer to perform its obligations under this
Warrant.

    

    

    (d)           Loss, Theft, Destruction of
Warrants.  Upon receipt of evidence satisfactory to the Issuer
of the ownership of and the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction, upon receipt of
indemnity or security satisfactory to the Issuer or, in the case of any such
mutilation, upon surrender and cancellation of such Warrant, the Issuer will
make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant,
a new Warrant of like tenor and representing the right to purchase the same
number of shares of Common Stock.

    

    4.           Adjustment of Warrant Price
and Warrant Share Number.  The number of shares of Common Stock
for which this Warrant is exercisable, and the price at which such shares may be
purchased upon exercise of this Warrant, shall be subject to adjustment from
time to time as set forth in this Section 4. The Issuer shall give the Holder
notice of any event described below which requires an adjustment pursuant to
this Section 4 in accordance with Section 5.

    

    (a)           Recapitalization,
Reorganization, Reclassification, Consolidation, Merger or
Sale.

    

    (i)           In
case the Issuer after the Original Issue Date shall do any of the following
(each, a “Triggering
Event”): (a) consolidate with or merge into any other Person and the
Issuer shall not be the continuing or surviving corporation of such
consolidation or merger, or (b) permit any other Person to consolidate with or
merge into the Issuer and the Issuer shall be the continuing or surviving Person
but, in connection with such consolidation or merger, any Capital Stock of the
Issuer shall be changed into or exchanged for Securities of any other Person or
cash or any other property, or (c) transfer all or substantially all of its
properties or assets to any other Person, or (d) effect a capital reorganization
or reclassification of its Capital Stock, then, and in the case of each such
Triggering Event, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the Holder of this Warrant
shall be entitled upon the exercise hereof at any time after the consummation of
such Triggering Event, to the extent this Warrant is not exercised prior to such
Triggering Event, to receive at the Warrant Price in effect at the time
immediately prior to the consummation of such Triggering Event in lieu of the
Common Stock issuable upon such exercise of this Warrant prior to such
Triggering Event, the Securities, cash and property to which such

     

    
      
        
        

      

      
        -6-

        
          

        

      

      
        
        

      

    

     

    Holder
would have been entitled upon the consummation of such Triggering Event if such
Holder had exercised the rights represented by this Warrant (without giving
effect to the limitations on exercise set forth in Section 8 hereof) immediately
prior thereto (including the right to elect the type of consideration, if
applicable), subject to adjustments (subsequent to such corporate action) as
nearly equivalent as possible to the adjustments provided for elsewhere in this
Section 4.  Unless the surviving entity in any such Triggering Event
is a public company under the Securities Exchange Act of 1934, the common equity
securities of which are traded or quoted on a national securities exchange or
the OTC Bulletin Board (a “Qualifying Entity”),
the Holder, at its option, shall be permitted to require that the Issuer pay to
the Holder an amount equal to the Black-Scholes value of this
Warrant.

    

    (ii)           Notwithstanding
anything contained in this Warrant to the contrary and so long as the surviving
entity is a Qualifying Entity, the Issuer will not be deemed to have
effected  any Triggering Event if, prior to the consummation thereof,
each Person (other than the Issuer) which may be required to deliver any
Securities, cash or property upon the exercise of this Warrant as provided
herein shall assume, by written instrument delivered to the Holder of this
Warrant and reasonably satisfactory to the Holder, (A) the obligations of the
Issuer under this Warrant (and if the Issuer shall survive the consummation of
such Triggering Event, such assumption shall be in addition to, and shall not
release the Issuer from, any continuing obligations of the Issuer under this
Warrant) and (B) the obligation to deliver to such Holder such shares of
Securities, cash or property as, in accordance with the foregoing provisions of
this subsection (a), such Holder shall be entitled to receive, and such Person
shall have similarly delivered to such Holder, an opinion of counsel for such
Person, which shall be reasonably satisfactory to the Holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of this subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to deliver upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

    

    (b)           Stock Dividends,
Subdivisions and Combinations.  If at any time the Issuer
shall:

    

    (i)           set
a record date or take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, shares of Common Stock,

    

    (ii)           subdivide
its outstanding shares of Common Stock into a larger number of shares of Common
Stock, or

    

    (iii)           combine
its outstanding shares of Common Stock into a smaller number of shares of Common
Stock,

    

    then (1)
the number of shares of Common Stock for which this Warrant is exercisable
immediately after the occurrence of any such event shall be adjusted to equal
the number of shares of Common Stock which a record holder of the same number of
shares of Common Stock for which this Warrant is exercisable immediately prior
to the occurrence of such event would

     

    
      
        
        

      

      
        -7-

        
          

        

      

      
        
        

      

    

     

    own or be
entitled to receive after the happening of such event (without giving effect to
the limitations on exercise set forth in Section 8 hereof), and (2) the Warrant
Price then in effect shall be adjusted to equal (A) the Warrant Price then in
effect multiplied by the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to the adjustment (without giving effect to the
limitations on exercise set forth in Section 8 hereof) divided by (B) the number
of shares of Common Stock for which this Warrant is exercisable immediately
after such adjustment (without giving effect to the limitations on exercise set
forth in Section 8 hereof).

    

    (c)           Adjustment upon Issuance of
shares of Common Stock.  If at any time the Issuer issues or
sells, or in accordance with this Section 4(c) 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 Issuer for a consideration per
share (the "New
Issuance Price") less than a price (the "Applicable Price")
equal to the Warrant 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 Warrant Price then in effect
shall be reduced to an amount equal to the New Issuance Price.  Upon
each such adjustment of the Warrant Price hereunder, the number of shares of
Warrant Stock shall be adjusted to the number of shares of Common Stock
determined by multiplying the Warrant Price in effect immediately prior to such
adjustment by the number of shares of Common Stock acquirable upon exercise of
this Warrant immediately prior to such adjustment and dividing the product
thereof by the Warrant Price resulting from such adjustment.  For
purposes of determining the adjusted Warrant Price under this Section 4(c), the
following shall be applicable:

    

    (i)           Issuance of
Options.  If the Issuer in any manner grants any options to
purchase Common Stock (“Options”), other than
Options granted to employees and consultants pursuant to any employee stock
benefit, option, purchase or similar plan approved by the Board,  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, exercise or exchange of any
stock or securities (other than Options) directly or indirectly convertible into
or exercisable or exchangeable for shares of Common Stock (“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 Issuer at the time of the
granting or sale of such Option for such price per share.  For
purposes of this Section 4(c)(i), the "lowest price per share for which one
share of Common Stock is issuable upon exercise of such Options or upon
conversion, exercise or exchange of such Convertible Securities issuable upon
exercise of any such Option" shall be equal to the sum of the lowest amounts of
consideration (if any) received or receivable by the Issuer with respect to any
one share 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 Warrant Price or number of shares of Warrant Stock 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.

     

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

    

    (ii)           Issuance of Convertible
Securities.  If the Issuer 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 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 Issuer at the time of
the issuance or sale of such Convertible Securities for such price per
share.  For the purposes of this Section 4(c)(ii), the "lowest price
per share for which one share of Common Stock is issuable upon the conversion,
exercise or exchange thereof" shall be equal to the sum of the lowest amounts of
consideration (if any) received or receivable by the Issuer with respect to one
share 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 Warrant Price or number of
shares of Warrant Stock 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 4(c), no further
adjustment of the Warrant Price or number of shares of Warrant Stock 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
Warrant Price and the number of shares of Warrant Stock in effect at the time of
such increase or decrease shall be adjusted to the Warrant Price and the number
of shares of Common Stock issuable upon exercise of this Warrant 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 4(c)(iii), if the terms of any Option or Convertible Security that was
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 4(c) shall be made if such adjustment would
result in an increase of the Warrant Price then in effect or a decrease in the
number of shares Warrant Stock.

    

    (iv)           Calculation of Consideration
Received.  In case any Option is issued in connection with the
issue or sale of other securities of the Issuer, together comprising one
integrated transaction in which no specific consideration is allocated to such
Options by the parties thereto, the Options 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 Issuer therefor.  If any shares of Common
Stock, Options or Convertible Securities are issued or sold for a
consideration

     

    
      
        
        

      

      
        -9-

        
          

        

      

      
        
        

      

    

     

    other
than cash, the amount of such consideration received by the Issuer 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 Issuer
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 Issuer 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 securities
will be determined jointly by the Issuer and the 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 Issuer and the 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
Issuer.

    

    (d)           Certain Other
Distributions.  If at any time the Issuer shall set a record
date or take a record of the holders of its Common Stock for the purpose of
entitling them to receive any divi­dend or other distribution
of:

    

    (i)           cash
(other than a cash dividend payable out of earnings or earned surplus legally
available for the payment of dividends under the laws of the jurisdiction of
incorporation of the Issuer),

    

    (ii)           any
evidences of its indebtedness, any shares of stock of any class or any other
securities or property of any nature whatsoever (other than cash or Common
Stock), or

    

    (iii)           any
warrants or other rights to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property of any nature whatsoever (other than cash or Common
Stock),

    

    then (1)
the number of shares of Common Stock for which this Warrant is exercisable shall
be adjusted to equal the product of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such adjustment (without
giving effect to the limitations on exercise set forth in Section 8 hereof)
multiplied by a fraction (A) the numerator of which shall be the Per Share
Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer and supported by an opinion from an investment banking firm reasonably
acceptable to the Holder) of any and all such evidences of indebtedness, shares
of stock, other securities or property or warrants or other subscription or
purchase rights so distributable, and (2) the Warrant Price then in effect shall
be adjusted to equal (A) the Warrant Price then in effect multiplied by the
number of shares of Common Stock

     

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

     

    for which
this Warrant is exercisable immediately prior to the adjustment (without giving
effect to the limitations on exercise set forth in Section 8 hereof) divided by
(B) the number of shares of Common Stock for which this Warrant is exercisable
immediately after such adjustment (without giving effect to the limitations on
exercise set forth in Section 8 hereof).  A reclassification of the
Common Stock (other than a change in par value, or from par value to no par
value or from no par value to par value) into shares of Common Stock and shares
of any other class of stock shall be deemed a distribution by the Issuer to the
holders of its Common Stock of such shares of such other class of stock within
the meaning of this Section 4(c) and, if the outstanding shares of Common Stock
shall be changed into a larger or smaller number of shares of Common Stock as a
part of such reclassification, such change shall be deemed a subdivision or
combination, as the case may be, of the outstanding shares of Common Stock
within the meaning of Section 4(b).

    

    (d)           Other Provisions applicable
to Adjustments under this Section.  The following provisions
shall be applicable to the making of adjustments of the number of shares of
Common Stock for which this Warrant is exercisable and the Warrant Price then in
effect provided for in this Section 4:

    

    (i) Fractional
Interests.  In computing adjustments under this Section 4,
fractional interests in Common Stock shall be taken into account to the nearest
one one-hundredth (1/100th) of a
share.

    

    (ii) When Adjustment Not
Required.  If the Issuer shall take a record of the holders of
its Common Stock for the purpose of entitling them to receive a dividend or
distribution or subscription or purchase rights and shall, thereafter and before
the distribution to stockholders thereof, legally abandon its plan to pay or
deliver such dividend, distribution, subscription or purchase rights, then
thereafter no adjustment shall be required by reason of the taking of such
record and any such adjustment previously made in respect thereof shall be
rescinded and annulled.

    

    (e)           Form of Warrant after
Adjustments.  The form of this Warrant need not be changed
because of any adjustments in the Warrant Price or the number and kind of
securities purchasable upon exercise of this Warrant.

    

    (f)           Escrow of
Property.  If after any property becomes distributable pursuant
to this Section 4 by reason of the taking of any record of the holders of Common
Stock, but prior to the occurrence of the event for which such record is taken,
and the Holder exercises this Warrant, such property shall be held in escrow for
the Holder by the Issuer to be distributed to the Holder upon and to the extent
that the event actually takes place, upon payment of the then current Warrant
Price.  Notwithstanding any other provision to the contrary herein, if
the event for which such record was taken fails to occur or is rescinded, then
such escrowed property shall be returned to the Issuer.

    

    5.           Notice of
Adjustments.  Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an “adjustment”), the Issuer shall cause its Chief
Financial Officer to prepare and execute a

     

    
      
        
        

      

      
        -11-

        
          

        

      

      
        
        

      

       

      certificate
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the Board made any determination
hereunder), and the Warrant Price and Warrant Share Number after giving effect
to such adjustment, and shall cause copies of such certificate to be delivered
to the Holder of this Warrant promptly after each adjustment.  Any
dispute between the Issuer and the Holder of this Warrant with respect to the
matters set forth in such certificate may at the option of the Holder of this
Warrant be submitted to one of the national accounting firms currently known as
the “big four” selected by the Holder, provided that the
Issuer shall have ten (10) days after receipt of notice from such Holder of its
selection of such firm to object thereto, in which case such Holder shall select
another such firm and the Issuer shall have no such right of objection, and
provided further that all
costs of such engagement shall be borne by the Issuer.  The firm
selected by the Holder of this Warrant as provided in the preceding sentence
shall be instructed to deliver a written opinion as to such matters to the
Issuer and such Holder within thirty (30) days after submission to it of such
dispute.  Such opinion shall be final and binding on the parties
hereto.

    

    

    6.           Fractional
Shares.  No fractional shares of Warrant Stock will be issued
in connection with any exercise hereof, but in lieu of such fractional shares,
the Issuer shall at its option either (a) make a cash payment therefor equal in
amount to the product of the applicable fraction multiplied by the Per Share
Market Value then in effect or (b) issue one whole share in lieu of such
fractional share.

    

    7.           [Reserved.]

    

    8. Certain Exercise
Restrictions.

     

    (a)           Notwithstanding
anything to the contrary set forth in this Warrant, at no time may a holder of
this Warrant exercise this Warrant if the number of shares of Common Stock to be
issued pursuant to such exercise would exceed, when aggregated with all other
shares of Common Stock owned by such holder at such time, the number of shares
of Common Stock which would result in such holder beneficially owning (as
determined in accordance with Section 13(d) of the Securities Exchange Act
of 1934, as amended, and the rules thereunder) in excess of 4.99% of all of the
Common Stock outstanding at such time; provided, however, that upon a holder of
this Warrant providing the Issuer with sixty-one (61) days notice (pursuant to
