STOCK PURCHASE WARRANT

To Purchase __________ Shares of Common Stock of

Summus, Inc. (USA)

THIS CERTIFIES that, for value received, _____________ (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 July __, 2002 (the “Initial
Exercise Date”) and on or prior to the close of business on the third anniversary of the Initial Exercise Date (the
“Termination Date”) but not thereafter, to subscribe for and purchase from Summus, Inc. (USA), a corporation
incorporated in the State of Florida (the “Company”), up to ____________ shares (the “Warrant
Shares”) of Common Stock, par value $0.001 per share, of the Company (the “Common Stock”).  The
purchase price of one share of Common Stock (the “Exercise Price”) under this Warrant shall be $_____,
subject to adjustment hereunder.  The Exercise Price and the number of Warrant Shares for which the Warrant is exercisable
shall be subject to adjustment as provided herein. Capitalized terms used and not otherwise defined herein shall have the
meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated July 18,
2002, between the Company and the investors signatory thereto.

1

   

1.      
Title to Warrant.  Prior to the Termination Date and subject to compliance with applicable laws, this Warrant and
all rights hereunder are transferable, in whole or in part, at the office or agency of the Company by the Holder in person or by
duly authorized attorney, upon surrender of this Warrant together with the Assignment Form annexed hereto properly endorsed.

2.      
Authorization of Shares.  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, be duly
authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously with such issue).

3.      
Exercise of Warrant. 

(a)      
Except as provided in Section 4 herein, exercise of the purchase rights represented by this Warrant may be made at any time or
times on or after the Initial Exercise Date and on or before the Termination Date by the surrender of this Warrant and the Notice
of Exercise Form annexed hereto duly executed, at the office of 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 such Holder appearing on the books of the Company)
and upon payment of the Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United
States bank or by means of a cashless exercise, the Holder shall be entitled to receive a certificate for the number of Warrant
Shares so purchased.  Certificates for shares purchased hereunder shall be delivered to the Holder within three (3) Trading
Days after the date on which this Warrant shall have been exercised as aforesaid. This Warrant shall be deemed to have been
exercised and such certificate or certificates 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 by payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, pursuant to
Section 5 prior to the issuance of such shares, have been paid.  If the Company fails to deliver to the Holder a certificate
or certificates representing the Warrant Shares pursuant to this Section 3(a) by the third Trading Day after the date of exercise,
then the Holder will have the right to rescind such exercise.  In addition to any other rights available to the Holder, if the
Company fails to deliver to the Holder a certificate or certificates representing the Warrant Shares pursuant to an exercise by the
fifth Trading Day after the date of exercise, and if after such fifth  Trading Day the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the
Holder anticipated receiving upon such exercise (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 Warrant Shares that the Company was required to deliver
to the Holder in connection with the exercise at issue

2

   

times (B) the closing bid price of the Common Stock at the time of the
obligation giving rise to such purchase obligation, and (2) 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 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 a market price on the date of exercise totaled $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. 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.

(b)       
If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or
certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of 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.

(c)      
Notwithstanding anything herein to the contrary, in no event shall the Holder be permitted to exercise this Warrant for Warrant
Shares to the extent that (i) the number of shares of Common Stock owned by such Holder (other than Warrant Shares issuable upon
exercise of this Warrant) plus (ii) the number of Warrant Shares issuable upon exercise of this Warrant, would be equal to or
exceed 4.9999% of the number of shares of Common Stock then issued and outstanding, including shares issuable upon exercise
of this Warrant held by such Holder after application of this Section 3(c).  As used herein, beneficial ownership shall be
determined in accordance with Section 13(d) of the Exchange Act.  To the extent that the limitation contained in this Section
3(c) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder) and of
which a portion of this Warrant is exercisable shall be in the sole discretion of such Holder, and the submission of a Notice of
Exercise shall be deemed to be such Holder’s determination of whether this Warrant is exercisable (in relation to other
securities owned by such Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate
percentage limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. 
Nothing contained herein shall be deemed to restrict the right of a Holder to exercise this Warrant into Warrant Shares at such
time as such exercise will not violate the provisions of this Section 3(c).  The provisions of this Section 3(c) may be waived
by the Holder upon, at the election of the Holder, not less than 61 days’ prior notice to the Company, and the provisions of
this Section 3(c) shall continue to apply until such 61st day (or such later date, as determined by the Holder, as may
be specified in such notice of waiver).  No exercise of this Warrant in violation of this Section 3(c) but otherwise in
accordance with this Warrant shall affect the status of the Warrant Shares as validly issued, fully-paid and
nonassessable.

3

   

(d)      
At anytime beginning one (1) year from the date this Warrant is issued, in the event that the Registration Statement
registering the Warrant Shares issuable hereunder is not then effective, this Warrant may also be exercised 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 average of the high and low trading prices per share of Common Stock on the

         Trading Day preceding the date of such
election;

(B) =  the Exercise Price of the Warrants; and

(X) =  the number of Warrant Shares issuable upon exercise of the Warrants in

           accordance with the
terms of this Warrant.

4.    
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 Holder would otherwise be entitled to purchase upon such
exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the Exercise Price.

5.    
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.

6.    
Closing of Books.  The Company will not close its stockholder books or records in any manner which prevents the
timely exercise of this Warrant.

7.    
Transfer, Division and Combination. 

(a)    
Subject to compliance with any applicable securities laws, transfer of this Warrant and all rights hereunder, in whole or in
part, shall be registered on the books of the Company to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, 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 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

4

   

assigned, and this Warrant shall promptly
be cancelled.  A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without
having a new Warrant issued. 

(b)    
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 7(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.

(c)    
The Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new Warrant or Warrants under
this Section 7.

(d)    
The Company agrees to maintain, at its aforesaid office, books for the registration and the registration of transfer of the
Warrants.

8.    
No Rights as Shareholder until Exercise.  This Warrant does not entitle the Holder to any voting rights or other
rights as a shareholder of the Company prior to the exercise hereof.  Upon the surrender of this Warrant and the payment of
the aggregate Exercise Price (or by means of a cashless exercise), the Warrant Shares so purchased shall be and be deemed to be
issued to such Holder as the record owner of such shares as of the close of business on the later of the date of such surrender or
payment.

9.    
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 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.

10.    
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 be a Saturday, Sunday or a legal holiday, then such action may be taken or such right
may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday.

11.    
Adjustments of Exercise Price and Number of Warrant Shares. 

(a)    
Stock Splits, etc.  The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise
Price shall be subject to adjustment from time to time upon the happening of any of the following.  In case the Company shall
(i) pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares
of

5

   

Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the Holder shall be entitled to receive the kind and number of Warrant Shares or other securities
of the Company which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. 
Upon each such adjustment of the kind and number of Warrant Shares or other securities of the Company which are purchasable
hereunder, the Holder shall thereafter be entitled to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately prior to such
adjustment and dividing by the number of Warrant Shares or other securities of the Company resulting from such adjustment.  An
adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event retroactive to
the record date, if any, for such event.

(b)    
Anti-Dilution Provisions.   During the Exercise Period, the Exercise Price and the number of Warrant
Shares issuable hereunder and for which this Warrant is then exercisable pursuant to Section 1 hereof shall be subject to
adjustment from time to time as provided in this Section 11(b).  In the event that any adjustment of the Exercise Price as
required herein results in a fraction of a cent, such Exercise Price shall be rounded up or down to the nearest cent.

(i)  Adjustment of Exercise Price.  If and whenever the Company issues or sells, or in accordance with Section
8(b) hereof is deemed to have issued or sold, any shares of Common Stock for a consideration per share of less than the then the
Exercise Price or for no consideration (such lower price, the “Base Share Price” and such issuances
collectively, a "Dilutive Issuance"), then, the Exercise Price shall be reduced to equal the Base Share Price,
provided, that for purposes hereof, all shares of Common Stock that are issuable upon conversion, exercise or exchange of
Capital Share Equivalents shall be deemed outstanding immediately after the issuance of such Common Stock.  Such adjustment
shall be made whenever such shares of Common Stock or Capital Share Equivalents are issued. 

(ii) Effect on Exercise Price of Certain Events.  For purposes of determining the adjusted Exercise Price under
Section 11(b) hereof, the following will be applicable:

  (A) Issuance of Rights or Options.  If the Company in any manner issues or grants any warrants, rights or
options, whether or not immediately exercisable, to subscribe for or to purchase Common Stock or other securities exercisable,
convertible into or exchangeable for Common Stock (“Convertible Securities”) (such warrants, rights and options
to purchase Common Stock or Convertible Securities are hereinafter referred to as “Options”) and the price per
share for which Common Stock is issuable upon the exercise of such Options is less than the Exercise Price (“Below Base
Price Options”), then the maximum total number of shares

6

   

of Common Stock issuable upon the exercise of all such Below
Base Price Options (assuming full exercise, conversion or exchange of Convertible Securities, if applicable) will, as of the date
of the issuance or grant of such Below Base Price Options, be deemed to be outstanding and to have been issued and sold by the
Company for such price per share.  For purposes of the preceding sentence, the “price per share for which Common Stock
is issuable upon the exercise of such Below Base Price Options” is determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or granting of all such Below Base Price Options, plus the
minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise of all such Below Base Price
Options, plus, in the case of Convertible Securities issuable upon the exercise of such Below Base Price Options, the minimum
aggregate amount of additional consideration payable upon the exercise, conversion or exchange thereof at the time such Convertible
Securities first become exercisable, convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise of all such Below Base Price Options (assuming full conversion of Convertible Securities, if
applicable).  No further adjustment to the Exercise Price will be made upon the actual issuance of such Common Stock upon the
exercise of such Below Base Price Options or upon the exercise, conversion or exchange of Convertible Securities issuable upon
exercise of such Below Base Price Options.

(B) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities, whether
or not immediately convertible (other than where the same are issuable upon the exercise of Options) and the price per share for
which Common Stock is issuable upon such exercise, conversion or exchange is less than the Exercise Price, then the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Convertible Securities will, as of
the date of the issuance of such Convertible Securities, be deemed to be outstanding and to have been issued and sold by the
Company for such price per share.  For the purposes of the preceding sentence, the “price per share for which Common
Stock is issuable upon such exercise, conversion or exchange” is determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or sale of all such Convertible Securities, plus the
minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise, conversion or exchange
thereof at the time such Convertible Securities first become exercisable, convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Convertible Securities.  No
further adjustment to the Exercise Price will be made upon the actual

7

   

 issuance of such Common Stock upon exercise, conversion or
exchange of such Convertible Securities.

(C) Change in Option Price or Conversion Rate.  If there is a change at any time in (i) the amount of additional
consideration payable to the Company upon the exercise of any Options; (ii) the amount of additional consideration, if any, payable
to the Company upon the exercise, conversion or exchange of any Convertible Securities; or (iii) the rate at which any Convertible
Securities are convertible into or exchangeable for Common Stock (in each such case, other than under or by reason of provisions
designed to protect against dilution), the Exercise Price in effect at the time of such change will be readjusted to the Exercise
Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such
changed additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold.

(D) Treatment of Expired Options and Unexercised Convertible Securities.  If, in any case, the total number of
shares of Common Stock issuable upon exercise of any Option or upon exercise, conversion or exchange of any Convertible Securities
is not, in fact, issued and the rights to exercise such Option or to exercise, convert or exchange such Convertible Securities
shall have expired or terminated, the Exercise Price then in effect will be readjusted to the Exercise Price which would have been
in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding
immediately prior to such expiration or termination (other than in respect of the actual number of shares of Common Stock issued
upon exercise or conversion thereof), never been issued.

(E) Calculation of Consideration Received.  If any Common Stock, Options or Convertible Securities are issued,
granted or sold for cash, the consideration received therefor for purposes of this Warrant will be the amount received by the
Company therefor, before deduction of reasonable commissions, underwriting discounts or allowances or other reasonable expenses
paid or incurred by the Company in connection with such issuance, grant or sale.  In case any Common Stock, Options or
Convertible Securities are issued or sold for a consideration part or all of which shall be other than cash, the amount of the
consideration other than cash received by the Company will be the fair market 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 Market Price
thereof as of the date of receipt.  In case any Common Stock, Options or Convertible Securities are issued in connection with
any merger or consolidation in which the Company is the surviving corporation, the amount of consideration therefor will be

8

   

deemed
to be the fair market value of such portion of the net assets and business of the non-surviving corporation as is attributable to
such Common Stock, Options or Convertible Securities, as the case may be.  The fair market value of any consideration other
than cash or securities will be determined in good faith by an investment banker or other appropriate expert of national reputation
selected by the Company and reasonably acceptable to the holder hereof, with the costs of such appraisal to be borne by the
Company.

(F) Exceptions to Adjustment of Exercise Price. 
No adjustment to the Exercise Price will be made (i) upon the
exercise of this Warrant or any other warrant of this series or of any other series issued by the Company in connection with the
offer and sale of this Company's securities pursuant to the Purchase Agreement; (ii) upon the exercise of or conversion of any
Convertible Securities, options or warrants issued and outstanding on the initial issuance date of this Warrant; (iii) upon the
grant or exercise of any Convertible Securities which may hereafter be granted or exercised under any employee benefit plan of the
Company now existing or to be implemented in the future, so long as the issuance of such Convertible Securities is approved by a
majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of
non-employee directors established for such purpose; (iv) upon the issuance of Common Stock or Convertible Securities in any
transaction of the nature contemplated by Rule 145, promulgated under the Securities Act; (v) in connection with any strategic
partnership or joint venture or acquisition or key consulting agreements (the primary purpose of which is not to raise equity
capital for the Company); or (vi) upon the issuance of any common stock pursuant to an equity line of credit transaction entered
between the Company and an investor identified and arranged by HPC Capital Management.

(iii) Notice of Adjustment.  Upon the occurrence of any event which requires any adjustment of the Exercise Price,
then, and in each such case, the Company shall give notice thereof to the holder of this Warrant, which notice shall state the
Exercise Price resulting from such adjustment and the increase or decrease in the number of Warrant Shares purchasable at such
price upon exercise, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is
based, provided that such notice shall not contain any material nonpublic information.  Such calculation shall be certified by
the chief financial officer of the Company.

(iv) Minimum Adjustment of Exercise Price.  No adjustment of the Exercise Price shall be made in an amount of less
than 1% of the Exercise Price in effect at the time such adjustment is otherwise required to be made, but any such lesser
adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together
with any

9

   

adjustments so carried forward, shall amount to not less than 1% of such Exercise Price.

(v) Certain Definitions.  "Common Stock Deemed Outstanding" shall mean the number of shares of Common Stock actually
outstanding (not including shares of Common Stock held in the treasury of the Company), plus (x) in the case of any adjustment
hereunder resulting from the issuance of any Options, the maximum total number of shares of Common Stock issuable upon the exercise
of the Options for which the adjustment is required (including any Common Stock issuable upon the conversion of Convertible
Securities issuable upon the exercise of such Options), and (y) in the case of any adjustment required hereunder resulting from the
issuance of any Convertible Securities, the maximum total number of shares of Common Stock issuable upon the exercise, conversion
or exchange of the Convertible Securities for which the adjustment is required, as of the date of issuance of such Convertible
Securities, if any. 

(c)            Voluntary Adjustment by the Company.  The
Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of
time deemed appropriate by the Board of Directors of the Company.

(d)            Notice of Adjustment.  Whenever the number of
Warrant Shares or number or kind of securities or other property purchasable upon the exercise of this Warrant or the Exercise
Price is adjusted, as herein provided, the Company shall promptly mail by registered or certified mail, return receipt requested,
to the Holder notice of such adjustment or adjustments setting forth the number of Warrant Shares (and other securities or
property) purchasable upon the exercise of this Warrant and the Exercise Price of such Warrant Shares (and other securities or
property) after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made.  Such notice, in the absence of manifest error, shall be conclusive evidence of
the correctness of such adjustment.

12.    
Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets.  In case the Company shall
reorganize its capital, reclassify its capital stock, consolidate or merge with or into another corporation (where the Company is
not the surviving corporation or where there is a change in or distribution with respect to the Common Stock of the Company), or
sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and,
pursuant to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common
stock of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature
whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common stock of the successor
or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, at their option, (a) upon exercise of this Warrant, the
number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,

10

   

reclassification, merger, consolidation or disposition of
assets by a Holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such event,
or (b) cash equal to the value of this Warrant as determined in accordance with the Black-Sholes option pricing formula.  In
case of any such reorganization, reclassification, merger, consolidation or disposition of assets, the successor or acquiring
corporation (if other than the Company) shall expressly assume the due and punctual observance and performance of each and every
covenant and condition of this Warrant to be performed and observed by the Company and all the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of Warrant Shares for which this Warrant is exercisable which shall
be as nearly equivalent as practicable to the adjustments provided for in this Section 12.  For purposes of this Section 12,
“common stock of the successor or acquiring corporation” shall include stock of such corporation of any class which is
not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption
and shall also include any evidences of indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a specified date or the happening of a specified event
and any warrants or other rights to subscribe for or purchase any such stock.  The foregoing provisions of this Section 12
shall similarly apply to successive reorganizations, reclassifications, mergers, consolidations or disposition of assets.

13.    
Voluntary Adjustment by the Company.  The Company may at any time during the term of this Warrant reduce the then
current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the
Company.

14.    
Notice of Adjustment.  Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested, to the Holder notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property) purchasable upon the exercise of this Warrant and the
Exercise Price of such Warrant Shares (and other securities or property) after such adjustment, setting forth a brief statement of
the facts requiring such adjustment and setting forth the computation by which such adjustment was made.  Such notice, in the
absence of manifest error, shall be conclusive evidence of the correctness of such adjustment.

15.    
Notice of Corporate Action.  If at any time:

(a)            the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other distribution, or any right to subscribe for or
purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property, or to receive any
other right, or

(b)            there shall be any capital reorganization of the Company,
any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger of the Company with, or
any sale, transfer or other disposition of

11

   

all or substantially all the property, assets or business of the Company to, another
corporation or,

(c)            there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at least 20 days’ prior written notice of the
date on which a record date shall be selected for such dividend, distribution or right or for determining rights to vote in respect
of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, liquidation or winding up, and
(ii) in the case of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution,
liquidation or winding up, at least 20 days’ prior written notice of the date when the same shall take place.  Such
notice in accordance with the foregoing clause also shall specify (i) the date on which any such record is to be taken for the
purpose of such dividend, distribution or right, the date on which the holders of Common Stock shall be entitled to any such
dividend, distribution or right, and the amount and character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up is to take place and
the time, if any such time is to be fixed, as of which the holders of Common Stock shall be entitled to exchange their Warrant
Shares for securities or other property deliverable upon such disposition, dissolution, liquidation or winding up.  Each such
written notice shall be sufficiently given if addressed to Holder at the last address of Holder appearing on the books of the
Company and delivered in accordance with Section 17(d).

16.    
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 Principal Market upon which the Common Stock may
be listed.

                       
            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 against impairment.  Without limiting the
generality of the foregoing, the Company will (a) 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, (b) 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 (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction

12

   

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.

Miscellaneous.

(a)    
Jurisdiction.  This Warrant shall constitute a contract under the laws of New York, without regard to its conflict
of law, principles or rules.

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

(c)    
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 Holder’s rights, powers or remedies, notwithstanding
all rights hereunder terminate on the Termination Date.  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 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 Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of
its rights, powers or remedies hereunder.

(d)    
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.

(e)    
Limitation of Liability.  No provision hereof, in the absence of affirmative action by Holder to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of 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.

(f)    
Remedies.  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 the defense in any action for specific performance that a remedy at law would be adequate.

(g)    
Successors and Assigns.  Subject to applicable securities laws, this Warrant and the rights and obligations
evidenced hereby shall inure to the benefit of

13

   

and be binding upon the successors of the Company and the successors and permitted
assigns of Holder.  The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this
Warrant and shall be enforceable by any such Holder or holder of Warrant Shares.

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

(i)    
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.

(j)    
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.

calendar quarter on a date, which shall be provided by the Board of Directors in

     Section 3. Meetings of Stockholders.
Meetings of stockholders may be held within or without the State of Delaware, as the
by-laws may provide. The books of the corporation may be kept (subject to any provisions
contained in the statutes) outside the State of Delaware at such place or places as may

No director of the corporation shall be personally liable to the corporation or any of

knowing violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, as the same exists or hereafter may be amended, or any successor provisions or (iv)

elimination or limitation of the liability of directors, then the liability of a director

5  

	

     Section 7. Right to Indemnification.   

	 	
     (A)
Each person who was or is made a party or is threatened to be made a party to or is
involved in any action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter, a "proceeding"), by reason of the fact that he or she, or a
person of whom he or she is the legal representative, is or was a director or officer, of
the corporation or, at the request of the corporation, of a partnership, joint venture,
trust or other enterprise, including service with respect to employee benefit plans,
whether the basis of such proceeding is alleged action in any official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by the
corporation to the fullest extent authorized by the Delaware General Corporation Law, as
the same exists or may hereafter be amended (but, in the case of any such amendment, only
to the extent that such amendment permits the corporation to provide broader
indemnification rights than said law permitted the corporation to provide prior to such
amendment), against all expense, liability and loss (including attorneys' fees,
judgments, fines, excise taxes or penalties under the Employee Retirement Income Security
Act of 1974, as amended, and amounts paid or to be paid in settlement) reasonably
incurred or suffered by such person in connection therewith and such indemnification
shall continue as to a person who has ceased to be a director, officer, employee or agent
and shall inure to the benefit of his or her heirs, executors and administrators;
provided, however, that, except as provided in paragraph (B) of this Article V, Section
7, the corporation shall indemnify any such person seeking indemnification in connection
with a proceeding (or part thereof) initiated by such person only if such proceeding (or
part thereof) was authorized by the Board of Directors of the corporation. The right to
indemnification conferred in this Article V, Section 7 shall be a contract right and
shall include the right to be paid by the corporation the expenses incurred in defending
any such proceeding in advance of its final disposition; provided, however, that, if the
Delaware General Corporation Law requires, the payment of such expenses incurred by a
director or officer in his or her capacity as a director or officer (and not in any other
capacity in which service was or is rendered by such person while a director or officer,
including, without limitation, service to an employee benefit plan) in advance of the
final disposition of a proceeding, shall be made only upon delivery to the corporation of
an undertaking, by or on behalf of such director or officer, to repay all amounts so
advanced if it shall ultimately be determined that such director or officer is not
entitled to be indemnified under this Article V, Section 7 or otherwise. The corporation
may, by action of its Board of Directors, provide indemnification to employees and agents
of the corporation with the same scope and effect as the foregoing indemnification of
directors and officers. 

	

6  

	 	
     (B)
If a claim under paragraph (A) of this Article V, Section 7 is not paid in full by the
corporation within thirty days after a written claim has been received by the
corporation, the claimant may at any time thereafter bring suit against the corporation
to recover the unpaid amount of the claim and, if successful in whole or in part, the
claimant shall be entitled to be paid also the expense of prosecuting such claim. It
shall be a defense to any such action (other than an action brought to enforce a claim
for expenses incurred in defending any proceeding in advance of its final disposition
where the required undertaking, if any is required, has been tendered to the corporation)
that the claimant has not met the standards of conduct which make it permissible under
the Delaware General Corporation Law for the corporation to indemnify the claimant for
the amount claimed, but the burden of proving such defense shall be on the corporation.
Neither the failure of the corporation (including its Board of Directors, independent
counsel, or its stockholders) to have made a determination prior to the commencement of
such action that indemnification of the claimant is proper in the circumstances because
he or she has met the applicable standard of conduct set forth in the Delaware General
Corporation Law, nor an actual determination by the corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the claimant has not met
such applicable standard or conduct, shall be a defense to the action or create a
presumption that the claimant has not met the applicable standard of conduct. 

	 	
     (C)
Non-Exclusivity of Rights. The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of its final disposition conferred in this
Article V, Section 7 shall not be exclusive of any other right which any person my have
or hereafter acquire under any statute, provision of the certificate of incorporation,
by-law, agreement, vote of stockholders or disinterested directors or otherwise.  

	 	
     (D)
Insurance. The corporation may maintain insurance, at its expense, to protect itself and
any director, officer, employee or agent of the corporation or another corporation,
partnership, joint venture, trust or other enterprise against such expense, liability or
loss, whether or not the corporation would have the power to indemnify such person
against such expense, liability or loss under the Delaware General Corporation Law.  

	

     Section 8. Arrangements with
Creditors or Stockholders. Whenever a compromise or arrangement is proposed between this
