	US $_____________ 	________, 2012 

FOR VALUE RECEIVED, Chile Mining Technologies Inc., a
Nevada corporation (the “Company”), promises to pay to
[__________________] (the “Holder”), the principal sum of
___________________ DOLLARS ($_________) (the “Principal”) in lawful
money of the United States of America, with interest payable thereon at the rate
of eleven percent (11%) per annum. The principal amount hereof and all accrued
but unpaid interest thereon shall be paid in full to the Holder on the five (5)
year anniversary of the date of this Note (the “Maturity Date”).

Capitalized terms used herein but not defined herein shall have
the meaning ascribed to them in that certain Securities Purchase Agreement,
dated of even date herewith (the “SPA”), pursuant to which the Holder is
acquiring this Note.

The following is a statement of the rights of the Holder of
this Note and the terms and conditions to which this Note is subject, and to
which the Holder, by acceptance of this Note, agrees: 

1.     Series. This Note is one of a series of Notes of the
Company in the aggregate principal amount of up to a maximum of Three Million
Five Hundred Thousand Dollars ($3,500,000) (collectively, the “Notes”) as
described in that certain Confidential Private Placement Memorandum delivered to
the Holder in connection with the transactions contemplated by the SPA (the
“Memorandum”).

2.     Principal Repayment. The outstanding principal amount
of this Note shall be payable on the Maturity Date, unless this Note has been
earlier converted or redeemed as described below. 

3.     Interest.

(a)     Computation. Interest (the “Interest”) shall
accrue on the unpaid principal amount of this Note from the date hereof until
such principal amount is repaid in full at the rate of eleven percent (11%) per
annum, payable quarterly in arrears on March 31, June 30, September 30
and December 31, with the initial payment due on September 30, 2012. For
purposes of clarity, the initial interest payment shall consist of accrued
interest from the date of issuance of the Note through September 30, 2012.
Thereafter, interest payments of accrued interest shall be due and payable as
set forth above until the Maturity Date, subject to earlier conversion or
redemption of the Note. All computations of the interest rate hereunder shall be
made on the basis of a 360-day year of twelve 30-day months. In the event that
any interest rate provided for herein shall be determined to be unlawful, such
interest rate shall be computed at the highest rate permitted by applicable law.
Any payment by the Company of any interest amount in excess of that permitted by
law shall be considered a mistake, with the excess being applied to the
principal of this Note without prepayment premium or penalty.

(b)     Taxes, Charges, and Expenses. The Company, at its
own cost, shall report interest income, if any, to the IRS and/or other
applicable tax authorities and to the Holder on a Form 1099-INT or other
appropriate form in accordance with applicable law. The Company shall bear sole
responsibility for any costs or fees in connection with the payment of Interest
with respect to this Note, including, but not limited to, wire transfer fees,
bank check fees and escrow agent fees. 

(c)     Closing Escrow Holdback. Pursuant to the SPA, an
amount equal to one (1) year of interest payments on the aggregate outstanding
principal of the Notes as of the Closing shall be retained by the Escrow Agent
and paid to the Investors and otherwise administered in accordance with the
Closing Escrow Agreement until such time as (i) 75% of the of the Notes have
been converted into Common Stock, or (ii) the Notes are fully redeemed. Promptly
following the occurrence of either (i) or (ii) in the preceding sentence, the
Escrow Agent shall release the funds to the Company. 

4.     Conversion. 

(a)     Generally. Each holder of the Notes shall have the
right, exercisable at any time prior to the Maturity Date, to convert all or any
portion of the principal amount then outstanding, plus all accrued but unpaid
interest thereon, into shares of the Company’s common stock, par value $0.001
per share (the “Common Stock”) at a conversion price (the “Conversion
Price”) equal to $2.00 per share, subject to adjustment in accordance with
Section 4(d) herein (the Common Stock underlying the Notes being referred to
herein as the “Shares”). 

(b)     Mechanics of Conversion. The conversion of this Note
shall be conducted in the following manner: upon any conversion of any portion
of the outstanding principal amount of this Note, plus all accrued but unpaid
interest thereon: (i) the Holder shall deliver a completed and executed Notice
of Conversion attached hereto as Exhibit A and, if such conversion is for the
entire outstanding principal amount due under this Note surrender and deliver
this Note, duly endorsed, to the Company’s office or such other address which
the Company shall designate against delivery of the certificates presenting the
Shares to be delivered; (ii) the Company shall, within three (3) Trading Days of receipt of the Notice of
Conversion cause the Company’s transfer agent to issue such required number of
Shares as set forth in the Conversion Notice. The Holder shall not be required
to physically surrender this Note to the Company until the Holder all of the
principal amount and accrued and unpaid interest under this Note have been
converted into shares of Common Stock or been paid in full, in which case, the
Holder shall surrender this Note to the Company for cancellation within three
(3) Trading Days of the date the final Notice of Conversion is delivered to the
Company. Partial conversions of this Note shall have the effect of lowering the
outstanding principal amount due hereunder. The Holder and the Company shall
maintain records showing the number of Shares purchased and the date of such
purchases. In the event of any dispute or discrepancy, the records of the
Company shall be controlling and determinative in the absence of manifest error.
The Holder and any assignee, by acceptance of this Note, acknowledge and
agree that, by reason of the provisions of this paragraph, the principal amount
due hereunder at any given time may be less than the amount stated on the face
hereof.  

2

(c)     Conversion Limitations. The Company shall not effect
any conversion of principal or interest under this Note, and a Holder shall not
have the right to convert any portion of this Note, to the extent that after
giving effect to such issuance after conversion as set forth on the applicable
Notice of Conversion, 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
conversion of this Note 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) conversion of the remaining, nonconverted portion of this Note
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 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 4(c), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder. To the extent that the limitation contained in this Section 4(c)
applies, the determination of whether this Note is convertible (in relation to
other securities owned by the Holder together with any Affiliates) and of which
portion of this Note is convertible shall be in the sole discretion of the
Holder, and the submission of a Notice of Conversion shall be deemed to be the
Holder’s determination of whether this Note is convertible (in relation to other
securities owned by the Holder together with any Affiliates) and of which
portion of this Note is convertible, 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. 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 Note, 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 4.9% 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 Note. 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 4(c), 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 conversion of this Note held by the
Holder and the provisions of this Section 4(c) 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 4(c) 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 Note.  

3

(d)     Delivery of Shares.

(i)     The Company shall, upon the written request of the Holder,
use its best efforts to deliver, or cause to be delivered, the Shares hereunder
electronically through the Depository Trust and Clearing Corporation or another
established clearing corporation performing similar functions, if available;
provided, that, the Company may, but will not be required to, change its
transfer agent if its current transfer agent cannot deliver the Shares
electronically through the Depository Trust and Clearing Corporation.

(ii)     To the extent permitted by law, the Company’s obligations
to issue and deliver Shares in accordance with the terms hereof are absolute and
unconditional, irrespective of any action or inaction by the Holder to enforce
the same, any waiver or consent with respect to any provision hereof, the
recovery of any judgment against any Person or any action to enforce the same,
or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder or any other Person of any obligation to
the Company or any violation or alleged violation of law by the Holder or any
other Person, and irrespective of any other circumstance that might otherwise
limit such obligation of the Company to the Holder in connection with the
issuance of Shares.

(iii)     If the Company fails to cause its transfer agent to
transmit to the Holder a certificate or the certificates (either physical or
electronic) representing the Conversion Shares pursuant to the terms hereof by
applicable delivery date, then, the Holder will have the right to rescind such
conversion. In addition, 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 Shares which the Holder anticipated
receiving upon such exercise, then the Company shall pay in cash to the Holder
the amount, if any, by which the Holder’s total purchase price (including
brokerage commissions, if any) for the shares of Common Stock so purchased
exceeds the amount obtained by multiplying (i) the number of Shares that the
Company was required to deliver to the Holder in connection with the conversion
at issue times (ii) the price at which the sell order giving rise to such
purchase obligation was executed. In addition, the Company will, at the option
of the Holder, either reinstate the principal and interest under the Note for
which the conversion was not honored (in which case such conversion 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 conversion
and delivery obligations hereunder. Nothing herein shall limit a Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with
respect to the Company’s failure to timely deliver certificates representing
shares of Common Stock upon conversion of the Note as required pursuant to the
terms hereof. 

4

(iv)     Issuance of certificates for 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. The
Company shall bear the cost of any legal opinion, transfer agent fees and
related costs in connection with the removal of restricted legend from any
certificate representing the Shares. Notwithstanding the foregoing, that in the
event certificates for Shares are to be issued in a name other than the name of
the Holder, this Note 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.

(e)     Company Conversion. If at any time from and
after the one year anniversary of the issuance of this Note (i) the volume
weighted average price (“VWAP) of the Common Stock equals or exceeds
$8.00 over any thirty (30) Trading Day period after such one year anniversary
(the “Trigger Price”) (subject to appropriate adjustments for any stock
dividend, stock split, stock combination, reclassification or similar
transaction after the Subscription Date) and (ii) the Company meets the Equity
Conditions (as defined below), then the Company shall have the right to require
the Holder to convert all or any portion of the principal and accrued interest
then remaining under this Note into validly issued, fully paid and
non-assessable shares of Common Stock in accordance with Section 4 hereof at the
Conversion Price in effect on the Mandatory Conversion Date (as defined below)
(a “Mandatory Conversion”). The Company may exercise its right to require
conversion under this Section 4(e) by delivering a written notice thereof by
facsimile and overnight courier to the Holder (the “Mandatory Conversion
Notice” and the date the Holder receives such notice by facsimile is
referred to as the “Mandatory Conversion Notice Date”). The Mandatory
Conversion Notice shall be irrevocable and shall (i) state the Trading Day
selected for the Mandatory Conversion in accordance with this Section 4(e),
which Trading Day shall be no sooner than five (5) Trading Days nor later than
thirty (30) Trading Days following the Mandatory Conversion Notice Date (the
“Mandatory Conversion Date”), (ii) the thirty (30) Trading Day period
over which the VWAP was calculated, (iii) the portion of the Conversion Amount
subject to the Mandatory Conversion pursuant to this Section 4(e)(i) and (iv)
the number of shares of Common Stock to be issued to the Holder on the Mandatory
Conversion Date (subject to adjustment for any adjustments to the Conversion
Price occurring under this Note after the execution of the Mandatory Conversion
Notice by the Company). Any portion of this Note converted by the Holder after
the Mandatory Conversion Notice Date shall reduce the Conversion Amount subject
to the applicable Mandatory Conversion that is required to be converted on the
Mandatory Conversion Date. The mechanics of conversion set forth in Section 4(b)
shall apply to any Mandatory Conversion as if the Company had received from the
Holder on the Mandatory Conversion Date a Conversion Notice with respect to the
Conversion Amount being converted pursuant to the Mandatory Conversion. For
purposes of this note “Equity Conditions” shall mean: (a) the Company shall have paid all amounts owing to the
Holder hereunder; (b) either (1) there is an effective registration statement
pursuant to which the Holder is permitted to utilize the prospectus thereunder
to resell all of the shares of Common Stock (and the Company believes, in good
faith, that such effectiveness will continue uninterrupted for the foreseeable
future) and there are a sufficient number of shares of Common Stock registered
on the effective registration statement to permit the conversion of the then
outstanding principal amount of the Note and the exercise of all then
outstanding Warrants issued to the holder or (2) all of the shares issuable may
be resold pursuant to Rule 144 without volume or manner-of-sale restrictions as
determined by the counsel to the Company pursuant to a written opinion letter to
such effect, addressed and acceptable to the Company’s transfer agent and the
Holder; (c) the Common Stock is trading on a trading market and all of the
shares issuable pursuant to the transaction documents are listed or quoted for
trading on such trading market (and the Company believes, in good faith, that
trading of the common stock on a trading market will continue uninterrupted for
the foreseeable future); (d) there is a sufficient number of authorized shares
of Common Stock for the issuance of all of the Shares; (e) there is no existing
Event of Default or no existing event which, with the passage of time or the
giving of notice, would constitute an Event of Default hereunder; (f) the
issuance of the Shares in question would not violate Beneficial Ownership
Limitations; (g) there has been no public announcement of a pending or proposed
fundamental transaction or change of control transaction that has not been
consummated, (h) the holder is not in possession of any information provided by,
or on behalf of, the Company or any of its subsidiaries or their respective
affiliates that constitutes, or may constitute, material non-public information;
and (i) for a period of 20 consecutive Trading Days prior to the applicable date
in question, the average daily trading volume for the Common Stock has exceeded
100,000 shares per Trading Day.

(f)     Adjustments to Conversion Price. 

(i)     Adjustments for Stock Splits and Combinations and
Stock Dividends. If the Company shall at any time or from time
to time after the date hereof, effect a stock split or combination of the
outstanding Common Stock or pay a stock dividend in shares of Common Stock, then
the Conversion Price shall be proportionately adjusted. Any adjustments under
this Section 4(c)(i) shall be effective at the close of business on the date the
stock split or combination becomes effective or the date of payment of the stock
dividend, as applicable. 

(ii)     Merger Sale, Reclassification, etc. In case
of any (A) consolidation or merger (including a merger in which the Company is
the surviving entity), (B) sale or other disposition of all or substantially all
of the Company’s assets or distribution of property to shareholders (other than
distributions payable out of earnings or retained earnings), or
reclassification, change or conversion of the outstanding securities of the
Company or of any reorganization of the Company (or any other corporation the
stock or securities of which are at the time receivable upon the conversion of
this Note) or any similar corporate reorganization on or after the date hereof,
then and in each such case the Holder of this Note, upon the conversion hereof
at any time thereafter shall be entitled to receive, in lieu of the stock or
other securities and property receivable upon the conversion hereof prior to
such consolidation, merger, sale or other disposition, reclassification, change,
conversion or reorganization, the stock or other securities or property to which
such Holder would have been entitled upon such consummation if such Holder had
converted this Note immediately prior thereto.

6

(g)     Elimination of Fractional Interests. No fractional
shares of Common Stock shall be issued upon conversion of this Note, nor shall
the Company be required to pay cash in lieu of fractional interests, it being
the intent of the parties that all fractional interests shall be eliminated and
that all issuances of Common Stock shall be rounded up to the nearest whole
share. 

5.     Redemption. From and after the two (2) year
anniversary of the issuance of the Notes, the Company will have the right to
redeem all or portion of the Notes at any time prior to the Maturity Date. The
Company must provide at least thirty (30) days prior notice to the Holders of a
redemption, during which time the holders may convert their Notes. The

amount plus any accrued and unpaid interest plus a redemption fee equal to 11%

an Event of Default if the Common Stock is, within ten (10) Business Days of the
effective date of such delisting, quoted on the OTCBB)), or the Company’s
failure to file reports with the SEC on a timely basis as required by the
Exchange Act; or 

(e)     Judgments. Any final, non-appealable judgment,

(i)     Bankruptcy. The Company shall: (i) admit in writing

receiver, sequestrator or other custodian for the Company or for any part of its
property; or (iv) permit or suffer to exist the commencement of any bankruptcy,
reorganization, debt arrangement or other case or proceeding under any
bankruptcy or insolvency law, or any dissolution, winding up or liquidation
proceeding, in respect of the Company, and, if such case or proceeding is not

then, and so long as such Event of Default is continuing for a
period of two (2) Business Days in the case of non-payment under Section 7(a), a
period of five (5) Business Days in the case of a cross-default under Section

Chile Mining Technologies Inc., a Nevada corporation (the
“Company”), hereby certifies that, for value received, the Initial Holder
shown above, or its permitted registered assigns (the “Holder”), is
entitled to purchase from the Company up to the number of shares of its common
stock, par value $0.001 per share (the “Common Stock”), shown above as
may be adjusted from time to time as provided herein (each such share, a
“Warrant Share” and all such shares, the “Warrant Shares”) at the
exercise price shown above as may be adjusted from time to time as provided
herein (the “Exercise Price”), at any time and from time to time on or
after the original issue date indicated above (the “Original Issue Date”)
and through and including the expiration time shown above (the “Expiration
Time”), and subject to the following terms and conditions: 

This Warrant is one of a series of warrants and is being issued
pursuant to a Securities Purchase Agreement, dated May 8, 2012 (the
“SPA”), by and between the Company, the Initial Holder and the other
parties thereto.

1.     Definitions. In addition to the terms defined
elsewhere in this Warrant, capitalized terms that are not otherwise defined
herein have the meanings given to such terms in the SPA. 

2.     List of Warrant Holders. 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 (which shall
include the Initial Holder or, as the case may be, any registered assignee to
which this Warrant is permissibly assigned hereunder 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. 

1 

3.     List of Transfers; Restrictions on Transfer. The
Company shall register any transfer of all or any portion of this Warrant in the
Warrant Register, upon surrender of this Warrant, with the Form of Assignment
attached hereto duly completed and signed, to the Company at its address
specified herein. Upon any such registration or transfer, a new Warrant to
purchase Common Stock, in substantially the form of this Warrant (any such new
Warrant, a “New Warrant”), evidencing the portion of this Warrant so
transferred shall be issued to the transferee and a New Warrant evidencing the
remaining portion of this Warrant not so transferred, if any, shall be issued to
the transferring Holder. The acceptance of the New Warrant by the transferee
thereof shall be deemed the acceptance by such transferee of all of the rights
and obligations in respect of the New Warrant that the Holder has in respect of
this Warrant. 

4.     Exercise and Duration of Warrant. 

(a)     All or any part of this Warrant shall be exercisable by the
registered Holder in any manner permitted by this Section 4 of this Warrant at
any time and from time to time on or after the Original Issue Date and through
and including the Expiration Time. At the Expiration Time, the portion of the
Warrant not exercised prior thereto shall be and become void and of no value and
this Warrant shall be terminated and shall no longer be outstanding. 

(b)     The Holder may exercise this Warrant by delivering to the
Company: (i) an exercise notice, in the form attached hereto (the “Exercise
Notice”), completed and duly signed, and (ii) payment by wire transfer of
immediately available funds to an account designated by the Company of the
Exercise Price for the number of Warrant Shares as to which this Warrant is
being exercised. The date such items are delivered to the Company (as determined
in accordance with the notice provisions hereof) is an “Exercise Date.”
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. In the event of any dispute or
discrepancy, the records of the Company shall be controlling and determinative
in the absence of manifest error. 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. 

(c)     Notwithstanding any provisions herein to the contrary, if
one or more registration statements under the Securities Act providing for the
resale of all shares of Common Stock underlying the Warrants have not been declared effective
by the U.S. Securities and Exchange Commission, or the prospectuses forming a
portion of such registration statement(s) is not then available for the resale
of all such shares of Common Stock, in lieu of exercising this Warrant by
payment of cash, the Holder may exercise this Warrant by a cashless exercise and
shall receive the number of shares of Common Stock equal to an amount (as
determined below) by surrender of this Warrant at the principal office of the
Issuer together with the properly endorsed Notice of Exercise in which event the
Issuer shall issue to the Holder a number of shares of Common Stock computed
using the following formula: 

2 

	  	X = 	Y (B-A) 
	  	  	     B 
	  	  	  
	Where 	X = 	the number of shares of Common Stock to be
      issued to the Holder. 
	  	  	  
		Y = 	the number of shares of Common Stock
      purchasable upon exercise of all of the Warrant or, if only a portion of
      the Warrant is being exercised, the portion of the Warrant being
      exercised. 
	  	  	  
	  	A = 	the Warrant Price. 
	  	  	  
		B = 	the closing price for the Common Stock on the
      Trading Day immediately preceding the date of the Notice of Exercise.
  

(d)     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)     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,
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 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 4(e), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder. To the extent that the limitation contained in this
Section 4(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. 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 4.9% 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 4(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 4(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 4(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.

5.     Delivery of Warrant Shares. 

(a)     Upon exercise of this Warrant, the Company shall promptly
(but in no event later than three (3) Trading Days after the Exercise Date)
issue or cause to be issued and cause to be delivered to or upon the written
order of the Holder and in such name or names as the Holder may designate, a
certificate for the Warrant Shares issuable upon such exercise, free of
restrictive legends. “Trading Day” shall mean a date on which the
Company’s Common Stock trades on its principal trading market. The Holder, or
any Person permissibly so designated by the Holder to receive Warrant Shares,
shall be deemed to have become the holder of record of such Warrant Shares as of
the Exercise Date.

(b)     The Company shall, upon the written request of the Holder,
use its best efforts to deliver, or cause to be delivered, Warrant Shares
hereunder electronically through the Depository Trust and Clearing Corporation
or another established clearing corporation performing similar functions, if
available; provided, that, the Company may, but will not be
required to, change its transfer agent if its current transfer agent cannot
deliver Warrant Shares electronically through the Depository Trust and Clearing
Corporation. If as of the time of exercise the Warrant Shares constitute
restricted or control securities, the Holder, by exercising, agrees not to
resell them except in compliance with all applicable securities laws. 

(c)     To the extent permitted by law, the Company’s obligations
to issue and deliver Warrant Shares in accordance with the terms hereof are
absolute and unconditional, irrespective of any action or inaction by the Holder
to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any
judgment against any Person or any action to enforce the same, or any setoff,
counterclaim, recoupment, limitation or termination, or any breach or alleged
breach by the Holder or any other Person of any obligation to the Company or any
violation or alleged violation of law by the Holder or any other Person, and
irrespective of any other circumstance that might otherwise limit such
obligation of the Company to the Holder in connection with the issuance of
Warrant Shares. 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. 

4 

(d)     If the Company fails to cause its transfer agent to
transmit to the Holder a certificate or the certificates (either physical or
electronic) representing the Warrant Shares pursuant to the terms hereof by
applicable delivery date, then, the Holder will have the right to rescind such
exercise. In addition, 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, then the Company shall pay in cash to
the Holder the amount, if any, by which the Holder’s total purchase price
(including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds the amount obtained by multiplying (i) the number of Warrant
Shares that the Company was required to deliver to the Holder in connection with
the exercise at issue times (ii) the price at which the sell order giving rise
to such purchase obligation was executed. In addition, the Company will 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. 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. 

6.     Charges, Taxes and Expenses. Issuance and delivery of
certificates for shares of Common Stock upon exercise of this Warrant shall be
made without charge to the Holder for any issue or transfer tax, withholding
tax, transfer agent fee or other incidental tax or expense in respect of the
issuance of such certificates, all of which taxes and expenses shall be paid by
the Company. The Company shall bear the cost of any legal opinion, transfer
agent fees and related costs in connection with the removal of restricted legend
from any certificate representing the Common Stock issuable upon exercise of
this Warrant. Notwithstanding the foregoing, the Company shall not be required
to pay any tax that may be payable in respect of any transfer involved in the
registration of any certificates for Warrant Shares or the Warrants in a name
other than that of the Holder. The Holder shall be responsible for all other tax
liability that may arise as a result of holding or transferring this Warrant or
receiving Warrant Shares upon exercise hereof.

5 

7.     Replacement of Warrant or Certificate. If this
Warrant or any certificate for Common Stock issued on exercise of this Warrant
shall become mutilated or defaced, or be destroyed, lost or stolen, the Company
shall execute and deliver a new warrant or certificate of like amount in
exchange and substitution for the mutilated or defaced Warrant or certificate,
or in lieu of and in substitution for the destroyed, lost or stolen Warrant or
certificate. In the case of a mutilated or defaced Warrant or certificate, the
Holder shall surrender such Warrant or certificate to the Company. In the case
of any destroyed, lost or stolen Warrant or certificate, the Holder shall
furnish to the Company: (i) evidence to its satisfaction of the destruction,
loss or theft of such Warrant or certificate and (ii) such security or indemnity
(which shall not include the posting of any bond) as may be reasonably required
by the Company to hold the Company harmless.

8.     Reservation of Warrant Shares. The Company covenants
that it will at all times reserve and keep available out of the aggregate of its
authorized but unissued and otherwise unreserved Common Stock, solely for the
purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as
herein provided, the number of Warrant Shares that are then issuable and
deliverable upon the exercise of this entire Warrant, free from preemptive
rights or any other contingent purchase rights of persons other than the Holder
(taking into account the adjustments and restrictions of Section 9). The Company
covenants that all Warrant Shares so issuable and deliverable shall, upon
issuance and the payment of the applicable Exercise Price in accordance with the
terms hereof, be duly and validly authorized, issued and fully paid and
nonassessable. 

9.     Certain Adjustments to Exercise Price. The Exercise
Price and number of Warrant Shares issuable upon exercise of this Warrant are
subject to adjustment from time to time as set forth in this Section 9. 

(a)     Adjustments for Stock Splits and Combinations and Stock
Dividends. If the Company shall at any time or from time to time after the
date hereof, effect a stock split or combination of the outstanding Common Stock
or pay a stock dividend in shares of Common Stock, then the Exercise Price and
the number of Warrant Shares issuable upon exercise of this Warrant shall be
proportionately adjusted such that the aggregate Exercise Price of this Warrant
shall remain unchanged. Any adjustments under this Section 9(a) shall be
effective at the close of business on the date the stock split or combination
becomes effective or the date of payment of the stock dividend, as applicable.

(b)     Merger Sale, Reclassification, etc. In case of any:
(i) consolidation or merger (including a merger in which the Company is the
surviving entity), (ii) sale or other disposition of all or substantially all of
the Company’s assets or distribution of property to shareholders (other than
distributions payable out of earnings or retained earnings), or (iii)
reclassification, change or conversion of the outstanding securities of the
Company or of any reorganization of the Company (or any other corporation the
stock or securities of which are at the time receivable upon the exercise of
this Warrant) or any similar corporate reorganization on or after the date
hereof, then and in each such case the Holder of this Warrant, upon the exercise
hereof at any time thereafter shall be entitled to receive, in lieu of the stock
or other securities and property receivable upon the exercise hereof prior to
such consolidation, merger, sale or other disposition, reclassification, change,
conversion or reorganization, the stock or other securities or property to which
such Holder would have been entitled upon such consummation if such Holder had exercised this Warrant immediately prior
thereto. To the extent that there are multiple types of securities, cash or
property to be received in a transaction, then the Company shall allocated the
Exercise Price among the consideration in a manner reasonably related to the
underlying value of each component of the consideration. If holders are given an
opportunity to select among different forms of consideration in a transaction,
then the Holder shall be given the same choice as to the consideration it
receives upon any exercise of this Warrant following such a transaction.
Notwithstanding anything to the contrary, in the event of a transaction that is
(x) an all cash transaction, (y) a "Rule 13e-3 transaction" as defined in Rule
13e-3 under the Exchange Act, or (z) a consolidation or sale (where the Company
is not the surviving corporation) involving a person or entity not traded on a
national securities exchange, including, but not limited to, the Nasdaq Global
Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market, the
Company or any Successor Entity (as defined below) shall, at the Holder’s
option, exercisable at any time concurrently with, or within 30 days after, the
consummation of the transaction, purchase this Warrant from the Holder by paying
to the Holder an amount of cash equal to the Black Scholes Value of the
remaining unexercised portion of this Warrant on the date of the consummation of
such transaction.

6 

10.     No Fractional Shares. No fractional Warrant Shares
will be issued in connection with any exercise of this Warrant. In lieu of any
fractional shares that would otherwise be issuable, the Company shall pay cash
equal to the product of such fraction multiplied by the closing price of one
Warrant Share as reported by the applicable Trading Market on the Exercise Date.

11.     Notices. Whenever the Exercise Price is adjusted
pursuant to any provision of Section 9, the Company shall promptly mail to the
Holder a notice setting forth the Exercise Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment. If (i)
the Company shall declare a dividend (or any other distribution in whatever
form) on the Common Stock, (ii) the Company shall declare a special nonrecurring
cash dividend on or a redemption of the Common Stock, (iii) 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, (iv) 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 (v) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company, then, in each case, the
Company shall cause to be mailed to the Holder at its last address as it shall
appear upon the Warrant Register of the Company, at least 20 calendar days prior
to the applicable record or effective date 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 is expected to become effective or
close, and the date as of which it is 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. The Holder shall remain entitled to exercise this 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.
Any and all notices or other communications or deliveries hereunder (including,
without limitation, any Exercise Notice) shall be delivered in accordance with
the procedures set forth in Section 9.2 of the SPA.

7 

12.     Warrant Agent. The Company shall serve as warrant
agent under this Warrant. Upon thirty (30) days’ notice to the Holder, the
Company may appoint a new warrant agent. Any corporation into which the Company
or any new warrant agent may be merged or any corporation resulting from any
consolidation to which the Company or any new warrant agent shall be a party or
any corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business shall
be a successor warrant agent under this Warrant without any further act. Any
such successor warrant agent shall promptly cause notice of its succession as
warrant agent to be mailed (by first class mail, postage prepaid) to the Holder
at the Holder’s last address as shown on the Warrant Register. 

13.     Miscellaneous. 

(a)     This Warrant shall be binding on and inure to the benefit
of the parties hereto and their respective successors and assigns. Subject to
the preceding sentence, nothing in this Warrant shall be construed to give to
