    THIS
SERIES EE COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies
that, for value received, _____________ or its assigns (the “Holder”) is entitled,
upon the terms and subject to the limitations on exercise and the conditions
hereinafter set forth, at any time on or after the date hereof (the “Initial Exercise
Date”) and on or prior to the close of business on August 9, 2015 (the
“Termination
Date”) but not thereafter, to subscribe for and purchase from Neoprobe
Corporation, a Delaware corporation (the “Company”), up to
______ shares (as subject to adjustment hereunder, the “Warrant Shares”) of
Common Stock. The purchase price of one share of Common Stock under this Warrant
shall be equal to the Exercise Price, as defined in Section

Company as of the date hereof pursuant to (i) Section 1 of the Engagement
Agreement, dated November 7, 2010, between the Company and Rodman & Renshaw,

    Section

    Section
2.             Exercise.

     

    a)           Exercise
of the purchase rights represented by this Warrant may be made, in whole or in
part, at any time or times on or after the Initial Exercise Date and on or
before the Termination Date by delivery to the Company (or such other office or
agency of the Company as it may designate by notice in writing to the registered
Holder at the address of the Holder appearing on the books of the Company) of a
duly executed facsimile copy of the Notice of Exercise Form annexed hereto.
Within three (3) Trading Days following the date of exercise as aforesaid, the
Holder shall deliver the aggregate Exercise Price for the shares specified in
the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a
United States bank unless the cashless exercise procedure specified in Section
2(c) below is specified in the applicable Notice of Exercise. Notwithstanding
anything herein to the contrary, the Holder shall not be required to physically
surrender this Warrant to the Company until the Holder has purchased all of the
Warrant Shares available hereunder and the Warrant has been exercised in full,
in which case, the Holder shall surrender this Warrant to the Company for
cancellation within three (3) Trading Days of the date the final Notice of
Exercise is delivered to the Company. Partial exercises of this Warrant
resulting in purchases of a portion of the total number of Warrant Shares
available hereunder shall have the effect of lowering the outstanding number of
Warrant Shares purchasable hereunder in an amount equal to the applicable number
of Warrant Shares purchased.  The Holder and the Company shall
maintain records showing the number of Warrant Shares purchased and the date of
such purchases. The Company shall deliver any objection to any Notice of
Exercise Form within one (1) Business Day of receipt of such
notice.  The Holder
and any assignee, by acceptance of this Warrant, acknowledge and agree that, by
reason of the provisions of this paragraph, following the purchase of a portion
of the Warrant Shares hereunder, the number of Warrant Shares available for
purchase hereunder at any given time may be less than the amount stated on the
face hereof.

     

    b)           Exercise
Price.  The exercise price per share of the Common Stock under
this Warrant shall be $2.375, subject to adjustment
hereunder (the “Exercise
Price”).

     

    c)           Cashless Exercise. If
at the time of exercise hereof there is no effective registration statement
registering, or the prospectus contained therein is not available for the
issuance of the Warrant Shares to the Holder and all of the Warrant Shares are
not then registered for resale by Holder into the market at market prices from
time to time on an effective registration statement for use on a continuous
basis (or the prospectus contained therein is not available for use), then this
Warrant may also be exercised, in whole or in part, at such time by means of a
“cashless exercise” in which the Holder shall be entitled to receive a
certificate for the number of Warrant Shares equal to the quotient obtained by
dividing [(A-B) (X)] by (A), where:

     

    
      
        
          	
                	
                  (A)

                	
                  =
      the VWAP (as defined below) on the Trading Day immediately preceding the
      date on which Holder elects to exercise this Warrant by means of a
      “cashless exercise,” as set forth in the applicable Notice of
      Exercise;

                


        

      

    

    


    
      
        	
              	
                (B)

              	
                =
      the Exercise Price of this Warrant, as adjusted hereunder;
    and

              


      

    

    


    
      
        
          	
                	
                  (X)

                	
                  =
      the number of Warrant Shares that would be issuable upon exercise of this
      Warrant in accordance with the terms of this Warrant if such exercise were
      by means of a cash exercise rather than a cashless
    exercise.

                


        

      

    

     

    
      
         


      

      
        2

        
          

        

      

      
         


      

    


    “VWAP” means, for any
date, the price determined by the first of the following clauses that applies:
(a) if the Common Stock is then listed or quoted on a Trading Market, the daily
volume weighted average price of the Common Stock for such date (or the nearest
preceding date) on the Trading Market on which the Common Stock is then listed
or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m.
(New York City time) to 4:02 p.m. (New York City time)), (b)  if the OTC
Bulletin Board is not a Trading Market, the volume weighted average price of the
Common Stock for such date (or the nearest preceding date) on the OTC Bulletin
Board, (c) if the Common Stock is not then listed or quoted for trading on the
OTC Bulletin Board and if prices for the Common Stock are then reported in the
“Pink Sheets” published by Pink OTC Markets, Inc. (or a similar organization or
agency succeeding to its functions of reporting prices), the most recent bid
price per share of the Common Stock so reported, or (d) in all other cases,
the fair market value of a share of Common Stock as determined by an independent
appraiser selected in good faith by the Holders of a majority in interest of the
Securities then outstanding and reasonably acceptable to the Company, the fees
and expenses of which shall be paid by the Company.

     

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

    


    d)           Mechanics of
Exercise.

     

    i.      Delivery of Certificates
Upon Exercise.  Certificates for shares purchased hereunder
shall be transmitted by the Transfer Agent to the Holder by crediting the
account of the Holder’s prime broker with The Depository Trust Company through
its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company
is then a participant in such system and either (A) there is an effective
registration statement permitting the issuance of the Warrant Shares to or
resale of the Warrant Shares by Holder or (B) this Warrant is being exercised
via cashless exercise and the Warrant Shares are eligible for resale by a
non-affiliate pursuant to Rule 144, and otherwise by physical delivery to the
address specified by the Holder in the Notice of Exercise by the date that is
three (3) Trading Days after the latest of (A) the delivery to the Company of
the Notice of Exercise, (B) surrender of this Warrant (if required) and (C)
payment of the aggregate Exercise Price as set forth above (including by
cashless exercise, if permitted) (such date, the “Warrant Share Delivery
Date”).   The Warrant Shares shall be deemed to have been
issued, and Holder or any other person so designated to be named therein shall
be deemed to have become a holder of record of such shares for all purposes, as
of the date the Warrant has been exercised, with payment to the Company of the
Exercise Price (or by cashless exercise, if permitted) and all taxes required to
be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the
issuance of such shares, having been paid..


    
      
         


      

      
        3

        
          

        

      

      
         


      

    


    ii.           Delivery of New Warrants
Upon Exercise.  If this Warrant shall have been exercised in
part, the Company shall, at the request of a Holder and upon surrender of this
Warrant certificate, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to the Holder a new Warrant evidencing the
rights of the Holder to purchase the unpurchased Warrant Shares called for by
this Warrant, which new Warrant shall in all other respects be identical with
this Warrant.

     

    iii.           Rescission
Rights.  If the Company fails to cause the Transfer Agent to
transmit to the Holder a certificate or the certificates representing the
Warrant Shares pursuant to Section 2(d)(i) by the second (2nd)
Trading Day following the Warrant Share Delivery Date, then the Holder will have
the right to rescind such exercise.

     

    iv.           Compensation for Buy-In on
Failure to Timely Deliver Certificates Upon Exercise.  In
addition to any other rights available to the Holder, if the Company fails to
cause the Transfer Agent to transmit to the Holder a certificate or the
certificates representing the Warrant Shares pursuant to an exercise on or
before the second (2nd)
Trading Day following the Warrant Share Delivery Date, and if after such date
the Holder is required by its broker to purchase (in an open market transaction
or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of
Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant
Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the
Company shall (A) pay in cash to the Holder the amount, if any, 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 (1) the number of Warrant Shares that the Company was required to
deliver to the Holder in connection with the exercise at issue times (2) the
price at which the sell order giving rise to such purchase obligation was
executed, and (B) at the option of the Holder, either reinstate the portion of
the Warrant and equivalent number of Warrant Shares for which such exercise was
not honored (in which case such exercise shall be deemed rescinded) or deliver
to the Holder the number of shares of Common Stock that would have been issued
had the Company 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 (A) 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 and, upon request of the Company,
evidence of the amount of such loss.  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 exercise of the Warrant as
required pursuant to the terms hereof.

    v.      No Fractional Shares or
Scrip.  No fractional shares or scrip representing fractional
shares shall be issued upon the exercise of this Warrant.  As to any
fraction of a share which the Holder would otherwise be entitled to purchase
upon such exercise, the Company shall, at its election, either pay a cash
adjustment in respect of such final fraction in an amount equal to such fraction
multiplied by the Exercise Price or round up to the next whole
share.

     

    vi.           Charges, Taxes and
Expenses.  Issuance of certificates for Warrant Shares shall be
made without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of such certificate, all of which
taxes and expenses shall be paid by the Company, and such certificates shall be
issued in the name of the Holder or in such name or names as may be directed by
the Holder; provided, however, that in the
event certificates for Warrant Shares are to be issued in a name other than the
name of the Holder, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the Holder
and the Company may require, as a condition thereto, the payment of a sum
sufficient to reimburse it for any transfer tax incidental thereto.

     

    vii.           Closing of
Books.  The Company will not close its stockholder books or
records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

    e)           Holder’s Exercise
Limitations.  The Company shall not effect any exercise of this
Warrant, and a Holder shall not have the right to exercise any portion of this
Warrant, pursuant to Section 2 or otherwise, to the extent that after giving
effect to such issuance after exercise as set forth on the applicable Notice of
Exercise, the Holder (together with the Holder’s Affiliates, and any other
Persons acting as a group together with the Holder or any of the Holder’s
Affiliates), would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below).  For purposes of the foregoing sentence, the
number of shares of Common Stock beneficially owned by the Holder and its
Affiliates shall include the number of shares of Common Stock issuable upon
exercise of this Warrant with respect to which such determination is being made,
but shall exclude the number of shares of Common Stock which would be issuable
upon (i) exercise of the remaining, nonexercised portion of this Warrant
beneficially owned by the Holder or any of its Affiliates and (ii) exercise or
conversion of the unexercised or nonconverted portion of any other securities of
the Company (including, without limitation, any other  Common Stock
Equivalents) subject to a limitation on conversion or exercise analogous to the
limitation contained herein beneficially owned by the Holder or any of its
Affiliates.  Except as set forth in the preceding sentence, for purposes of
this Section 2(e), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder, it being acknowledged by the Holder that the Company is not
representing to the Holder that such calculation is in compliance with Section
13(d) of the Exchange Act and the Holder is solely responsible for any schedules
required to be filed in accordance therewith.   To the extent
that the limitation contained in this Section 2(e) applies, the determination of
whether this Warrant is exercisable (in relation to other securities owned by
the Holder together with any Affiliates) and of which portion of this Warrant is
exercisable shall be in the sole discretion of the Holder, and the submission of
a Notice of Exercise shall be deemed to be the Holder’s determination of whether
this Warrant is exercisable (in relation to other securities owned by the Holder
together with any Affiliates) and of which portion of this Warrant is
exercisable, in each case subject to the Beneficial Ownership Limitation, and
the Company shall have no obligation to verify or confirm the accuracy of such
determination.   In addition, a determination as to any group
status as contemplated above shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated
thereunder.  For purposes of this Section 2(e), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock as reflected in (A) the Company’s most recent
periodic or annual report filed with the Commission, as the case may be, (B) a
more recent public announcement by the Company or (C) a more recent written
notice by the Company or the Transfer Agent setting forth the number of shares
of Common Stock outstanding.  Upon the written or oral request of a Holder,
the Company shall within two Trading Days confirm orally and in writing to the
Holder the number of shares of Common Stock then outstanding.  In any case,
the number of outstanding shares of Common Stock shall be determined after
giving effect to the conversion or exercise of securities of the Company,
including this Warrant, by the Holder or its Affiliates since the date as of
which such number of outstanding shares of Common Stock was
reported.  The “Beneficial Ownership
Limitation” shall be 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant.  The Holder, upon not
less than 61 days’ prior notice to the Company, may increase or decrease the
Beneficial Ownership Limitation provisions of this Section 2(e), provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the
issuance of shares of Common Stock upon exercise of this Warrant held by the
Holder and the provisions of this Section 2(e) shall continue to
apply.  Any such increase or decrease will not be effective until the
61st
day after such notice is delivered to the Company.  The provisions of
this paragraph shall be construed and implemented in a manner otherwise than in
strict conformity with the terms of this Section 2(e) to correct this paragraph
(or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation herein contained or to make changes or
supplements necessary or desirable to properly give effect to such limitation.
The limitations contained in this paragraph shall apply to a successor holder of
this Warrant.

    Section
3.             Certain
Adjustments.

     

    a)           Stock Dividends and
Splits. If the Company, at any time while this Warrant is outstanding:
(i) pays a stock dividend or otherwise makes a distribution or distributions on
shares of its Common Stock or any other equity or equity equivalent securities
payable in shares of Common Stock (which, for avoidance of doubt, shall not
include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger
number of shares, (iii) combines (including by way of reverse stock split)
outstanding shares of Common Stock into a smaller number of shares, or (iv)
issues by reclassification of shares of the Common Stock any shares of capital
stock of the Company, then in each case the Exercise Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common
Stock (excluding treasury shares, if any) outstanding immediately before such
event and of which the denominator shall be the number of shares of Common Stock
outstanding immediately after such event, and the number of shares issuable upon
exercise of this Warrant shall be proportionately adjusted such that the
aggregate Exercise Price of this Warrant shall remain unchanged.  Any
adjustment made pursuant to this Section 3(a) shall become effective immediately
after the record date for the determination of stockholders entitled to receive
such dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or
re-classification.

     

    b)           [RESERVED]

     

    c)           Subsequent Rights
Offerings.  If the Company, at any time while the Warrant is
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holder) entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the VWAP on the record date
mentioned below, then the Exercise Price shall be multiplied by a fraction, of
which the denominator shall be the number of shares of the Common Stock
outstanding on the date of issuance of such rights, options or warrants plus the
number of additional shares of Common Stock offered for subscription or
purchase, and of which the numerator shall be the number of shares of the Common
Stock outstanding on the date of issuance of such rights, options or warrants
plus the number of shares which the aggregate offering price of the total number
of shares so offered (assuming receipt by the Company in full of all
consideration payable upon exercise of such rights, options or warrants) would
purchase at such VWAP.  Such adjustment shall be made whenever such
rights, options or warrants are issued, and shall become effective immediately
after the record date for the determination of stockholders entitled to receive
such rights, options or warrants.

     

    d)           Pro Rata
Distributions.  If the Company, at any time while this Warrant
is outstanding, shall distribute to all holders of Common Stock (and not to the
Holder) evidences of its indebtedness or assets (including cash and cash
dividends) or rights or warrants to subscribe for or purchase any security, then
in each such case the Exercise Price shall be adjusted by multiplying the
Exercise Price in effect immediately prior to the record date fixed for
determination of stockholders entitled to receive such distribution by a
fraction of which the denominator shall be the VWAP determined as of the record
date mentioned above, and of which the numerator shall be such VWAP on such
record date less the then per share fair market value at such record date of the
portion of such assets or evidence of indebtedness so distributed applicable to
one outstanding share of the Common Stock as determined by the Board of
Directors in good faith.  In either case the adjustments shall be
described in a statement provided to the Holder of the portion of assets or
evidences of indebtedness so distributed or such subscription rights applicable
to one share of Common Stock.  Such adjustment shall be made whenever
any such distribution is made and shall become effective immediately after the
record date mentioned above.

    e)           Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the
Company, directly or indirectly, in one or more related transactions effects any
merger or consolidation of the Company with or into another Person, (ii) the
Company, directly or indirectly, effects any sale, lease, license, assignment,
transfer, conveyance or other disposition of all or substantially all of its
assets in one or a series of related transactions, (iii) any, direct or
indirect, purchase offer, tender offer or exchange offer (whether by the Company
or another Person) is completed pursuant to which holders of Common Stock are
permitted to sell, tender or exchange their shares for other securities, cash or
property and has been accepted by the holders of 50% or more of the outstanding
Common Stock, or (iv) the Company, directly or indirectly, in one or more
related transactions effects any reclassification, reorganization or
recapitalization of the Common Stock or any compulsory share exchange pursuant
to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property, (each a “Fundamental
Transaction”), then, the Company shall make appropriate provision to
ensure that the Holder will thereafter receive upon an exercise of this Warrant
at any time after the consummation of a Fundamental Transaction but before the
Termination Date, in lieu of the Warrant Shares (or other stock, securities,
cash, assets or other property whatsoever) issuable upon the exercise of this
Warrant immediately prior to such Fundamental Transaction, such shares of stock,
securities, cash, assets or any other property whatsoever (including warrants or
other purchase or subscription rights) which the Holder would have been entitled
to receive upon the happening of such Fundamental Transaction had this Warrant
been exercised immediately before such Fundamental Transaction (without regard
to any limitations on the exercise of this Warrant). If any holder of Common
Stock is given any choice as to the stock, securities, cash, assets or any other
property whatsoever (including warrants or other purchase or subscription
rights) to be received in a Fundamental Transaction, then the Holder shall be
given the same choice as to what it receives upon any exercise of this Warrant
following such Fundamental Transaction. The Company shall cause any successor
entity in a Fundamental Transaction in which the Company is not the survivor
(the “Successor
Entity”) to assume in writing all of the obligations of the Company under
this Warrant and the other Transaction Documents in accordance with the
provisions of this Section 3(e) pursuant to written agreements in form and
substance reasonably satisfactory to the Holder and approved by the Holder
(without unreasonable delay) prior to such Fundamental Transaction. Upon the
occurrence of any such Fundamental Transaction, the Successor Entity shall
succeed to, and be substituted for (so that from and after the date of such
Fundamental Transaction, the provisions of this Warrant and the other
Transaction Documents referring to the “Company” shall refer instead to the
Successor Entity), and may exercise every right and power of the Company and
shall assume all of the obligations of the Company under this Warrant and the
other Transaction Documents with the same effect as if such Successor Entity had
been named as the Company herein.

    f)           
Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the
nearest 1/100th of a share, as the case may be. For purposes of this Section 3,
the number of shares of Common Stock deemed to be issued and outstanding as of a
given date shall be the sum of the number of shares of Common Stock (excluding
treasury shares, if any) issued and outstanding.

     

    g)           Notice to
Holder.

     

    i.       Adjustment to Exercise
Price. Whenever the Exercise Price is adjusted pursuant to any provision
of this Section 3, the Company shall promptly mail to the Holder a notice
setting forth the Exercise Price after such adjustment and any resulting
adjustment to the number of Warrant Shares and setting forth a brief statement
of the facts requiring such adjustment.

     

    ii.      Notice to Allow Exercise by
Holder. If (A) the Company shall declare a dividend (or any other
distribution in whatever form) on the Common Stock, (B) the Company shall
declare a special nonrecurring cash dividend on or a redemption of the Common
Stock, (C) the Company shall authorize the granting to all holders of the Common
Stock rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights, (D) the approval of any stockholders of the
Company shall be required in connection with any reclassification of the Common
Stock, any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, or any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property, or (E) the Company shall authorize the voluntary
or involuntary dissolution, liquidation or winding up of the affairs of the

hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, redemption, rights or
warrants, or if a record is not to be taken, the date as of which the holders of
the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer or share exchange

expected that holders of the Common Stock of record shall be entitled to
exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange; provided that the failure to mail such notice or any defect
therein or in the mailing thereof shall not affect the validity of the corporate
action required to be specified in such notice.  To the extent that
any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of the Subsidiaries, the Company shall
simultaneously file such notice with the Commission pursuant to a Current Report

Warrant during the period commencing on the date of such notice to the effective
date of the event triggering such notice except as may otherwise be expressly
set forth herein.

    Section
4.             Transfer of
Warrant.

     

    a)           Transferability.  For a period of six months after the issue date of this
Warrant (which shall not be earlier than the closing date of the offering
pursuant to which this Warrant is being
issued), neither this Warrant nor any Warrant Shares issued upon exercise of
this Warrant shall be sold, transferred, assigned, pledged, or hypothecated, or
be the subject of any hedging, short sale, derivative, put, or call
transaction that would result in the effective economic
disposition of the securities by any person for a period of 180 days immediately
following the date of effectiveness or commencement of sales of the offering
pursuant to which this Warrant is being issued, except the
transfer of any security:

     

    
      	
               
      

            	
              i.

            	
              by operation of law or by reason of reorganization
      of the Company;

            


    

     

    
      	
               
      

            	
              ii.

            	
              to any FINRA member firm participating in the
      offering and the officers or partners thereof, if all securities so
      transferred remain subject to the
      lock-up restriction in this Section 4(a) for the remainder of the time
      period;

            


    

     

    
      	
               
      

            	
              iii.

            	
              if the aggregate amount of securities of the
      Company held by the Holder or related person do not exceed 1% of the
      securities being offered;

            


    

     

    
      	
               
      

            	
              iv.

            	
              that is beneficially owned on a pro-rata basis by all equity owners of an
      investment fund, provided that no participating member manages or
      otherwise directs investments by the fund, and participating members in
      the aggregate do not own more than 10% of the equity in the fund;
       or

            


    

     

    
      	
               
      

            	
              v.

            	
              the exercise or conversion of any security, if all
      securities received remain subject to the lock-up restriction in this
      Section 4(a) for the remainder of the time
  period.

            


    

     

    Subject to the foregoing restriction, any applicable
securities laws and the conditions set
forth in Section 4(d), this Warrant and all rights hereunder are
transferable, in whole or in part, upon surrender of this Warrant at the
principal office of the Company or its designated agent, together with a written
assignment of this Warrant substantially in the form attached hereto duly
executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer.  Upon such
surrender and, if required, such payment, the Company shall execute and deliver
a new Warrant or Warrants in the name of the assignee or assignees, as
applicable, and in the denomination or denominations specified in such
instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled.  The Warrant, if properly assigned in
accordance herewith, may be exercised by a new holder for the purchase of
Warrant Shares without having a new Warrant issued.

     

    
      
         


      

      
        10

        
          

        

      

      
         


      

    

     

    b)           New Warrants. This
Warrant may be divided or combined with other Warrants upon presentation hereof
at the aforesaid office of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney.  Subject to compliance
with Section 4(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice. All Warrants issued on transfers or exchanges shall be dated
the initial issuance date of this Warrant and shall be identical with this
Warrant except as to the number of Warrant Shares issuable pursuant
thereto.

     

    c)           Warrant Register. The
Company shall register this Warrant, upon records to be maintained by the
Company for that purpose (the “Warrant Register”),
in the name of the record Holder hereof from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, absent actual notice to the
contrary.

     

    d)           Transfer
Restrictions. If, at the time of
the surrender of this Warrant in connection
with any transfer of this Warrant or the sale of Warrant Shares, the transfer of
this Warrant or the Warrant Shares, as applicable, shall not be either (i)
registered pursuant to an effective registration statement under the
Securities Act and under applicable state securities or blue sky laws or (ii)
eligible for resale by a non-affiliate pursuant to Rule 144, the Company may
require, as a condition of allowing such transfer or sale, that the Holder
provide to the Company an opinion of counsel selected by the Holder
and reasonably acceptable to the Company, the form and substance of which
opinion shall be reasonably satisfactory to the Company, to the effect that such
transfer or sale does not require registration of such
transferred security under the Securities Act.  If the conditions in
clause (i) or (ii) herein are not satisfied, the Company may include on such new
Warrant (in the event of a transfer of this Warrant) or Warrant Shares (in the
event of sale of the Warrant Shares) a customary
legend.

     

    e)           Representations by the
Holder.  The Holder, by the
acceptance hereof, represents and warrants that (a) it is acquiring this Warrant
and, upon any exercise hereof, will acquire the Warrant Shares issuable upon
such exercise, for its own account and not
with a view to or for distributing or reselling such Warrant Shares or any part
thereof in violation of the Securities Act or any applicable state securities
law, except pursuant to sales registered or exempted under the Securities Act
and (b) at the time the Holder was offered
this Warrant, it was, and as of the date hereof it is, and on each date on which
it exercises this Warrants, it will either be an “accredited investor” as defined in Rule 501(a) under the
Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities
Act.


    
      
         


      

      
        11

        
          

        

      

      
         


      

    

     

    f)           Acknowledgement by
Company.  The Company
acknowledges and agrees that Holder may from time to time pledge pursuant to a
bona fide margin agreement with a registered broker-dealer, or grant a security interest
in, this Warrant and the Warrant Shares issuable upon exercise of this Warrant
to a financial institution that is an “accredited investor” as defined in Section 501(a) under the Securities Act
and, if required pursuant to the terms of such arrangement, such
Holder may transfer the pledged or secured Warrant and Warrant Shares to the
pledgees or secured parties, provided that such pledge or grant of security
interest is in compliance with applicable securities
laws.

     

    Section
5.             Miscellaneous.

     

    a)           No Rights as Stockholder
Until Exercise.  This Warrant does not entitle the Holder to
any voting rights, dividends or other rights as a stockholder of the Company
prior to the exercise hereof as set forth in Section 2(d)(i).

     

    b)           Loss, Theft, Destruction or
Mutilation of Warrant. The Company covenants that upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant or any stock certificate relating to
the Warrant Shares, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it (which, in the case of the Warrant, shall
not include the posting of any bond), and upon surrender and cancellation of
such Warrant or stock certificate, if mutilated, the Company will make and
deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

     

    c)           Saturdays, Sundays,
Holidays, etc.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall not
be a Business Day, then, such action may be taken or such right may be exercised
on the next succeeding Business Day.

     

    d)           Authorized
Shares.

     

    The
Company covenants that, during the period the Warrant is outstanding, it will
reserve from its authorized and unissued Common Stock a sufficient number of
shares to provide for the issuance of the Warrant Shares upon the exercise of
any purchase rights under this Warrant.  The Company further covenants
that its issuance of this Warrant shall constitute full authority to its
officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant.  The Company will
take all such reasonable action as may be necessary to assure that such Warrant
Shares may be issued as provided herein without violation of any applicable law
or regulation, or of any requirements of the Trading Market upon which the
Common Stock may be listed.  The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant and payment for such Warrant Shares in accordance herewith, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges created by the Company in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously with
such issue).

     

    
      
         


      

      
        12

        
          

        

      

      
         


      

    

     

    Except
and to the extent as waived or consented to by the Holder, the Company shall not
by any action, including, without limitation, amending its certificate 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 of this
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 Holder as set forth in this Warrant against
impairment.  Without limiting the generality of the foregoing, the
Company will (i) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in
par value, (ii) take all such action as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares upon the exercise of this Warrant and (iii) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof, as may be,
necessary to enable the Company to perform its obligations under this
Warrant.

     

    Before
taking any action which would result in an adjustment in the number of Warrant
Shares for which this Warrant is exercisable or in the Exercise Price, the
Company shall obtain all such authorizations or exemptions thereof, or consents
thereto, as may be necessary from any public regulatory body or bodies having
jurisdiction thereof.

     

    e)           Jurisdiction. All
questions concerning the construction, validity, enforcement and interpretation
of this Warrant shall be determined in accordance with the provisions of the
Purchase Agreement.

     

    f)           Restrictions.  The
Holder acknowledges that the Warrant Shares acquired upon the exercise of this
Warrant, if not registered, and the Holder does not utilize cashless exercise,
will have restrictions upon resale imposed by state and federal securities
laws.

     

    g)           Nonwaiver and
Expenses.  No course of dealing or any delay or failure to
exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice the Holder’s rights, powers or
remedies.  Without limiting any other provision of this Warrant or the
Purchase Agreement, if the Company willfully and knowingly fails to comply with
any provision of this Warrant, which results in any material damages to the
Holder, the Company shall pay to the Holder such amounts as shall be sufficient
to cover any costs and expenses including, but not limited to, reasonable
attorneys’ fees, including those of appellate proceedings, incurred by the
Holder in collecting any amounts due pursuant hereto or in otherwise enforcing
any of its rights, powers or remedies hereunder.

     

    
      
         


      

      
        13

        
          

        

      

      
         


      

    

     

    h)           Notices.  Any
notice, request or other document required or permitted to be given or delivered
to the Holder by the Company shall be delivered in accordance with the notice
provisions of the Purchase Agreement.

     

    i)           Limitation of
Liability.  No provision hereof, in the absence of any
affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder,
shall give rise to any liability of the Holder for the purchase price of any
Common Stock or as a stockholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company.

     

    j)           Remedies.  The
Holder, in addition to being entitled to exercise all rights granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Warrant.  The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of the provisions of this Warrant and hereby agrees to waive and not to
assert the defense in any action for specific performance that a remedy at law
would be adequate.

     

    k)           Successors and
Assigns.  Subject to applicable securities laws, this Warrant
and the rights and obligations evidenced hereby shall inure to the benefit of
and be binding upon the successors and permitted assigns of the Company and the
successors and permitted assigns of Holder.  The provisions of this
Warrant are intended to be for the benefit of any Holder from time to time of
this Warrant and shall be enforceable by the Holder or holder of Warrant
Shares.

     

    l)           Amendment.  This
Warrant may be modified or amended or the provisions hereof waived with the
written consent of the Company and the Holder.

     

    m)           Severability.  Wherever
possible, each provision of this Warrant shall be interpreted in such manner as
to be effective and valid under applicable law, but if any provision of this
Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provisions or the remaining provisions of
this Warrant.

     

    n)           Headings.  The
headings used in this Warrant are for the convenience of reference only and
shall not, for any purpose, be deemed a part of this Warrant.
