COMMON STOCK PURCHASE WARRANT

	
Warrant No. [   ]
	
Date of Original Issuance: December 19, 2005       

8x8, Inc., a Delaware corporation (the "Company"), hereby certifies that, for value received,
[CASTLERIGG MASTER INVESTMENTS LTD.] [KINGS ROAD INVESTMENTS LTD.] or its registered assigns (the "Holder"),
is entitled to purchase from the Company up to a total of Eight Hundred Ninety-Two Thousand Eight Hundred Fifty-Seven (892,857)
shares of common stock, $0.001 par value per share (the "Common Stock"), of the Company (as adjusted from time to time as
provided in Section 9, each such share, a "Warrant Share" and all such shares, the "Warrant Shares") at an exercise
price (as adjusted from time to time as provided in Section 9, the "Exercise Price") per Warrant Share equal to $3.00 at any
time and from time to time from and after the date hereof and until the expiration of this Warrant (as provided in Section 4), and subject
to the following terms and conditions:

	Definitions.  In addition to the terms defined elsewhere in this Warrant, capitalized terms that are
not otherwise defined herein and that are defined in the Securities Purchase Agreement, dated as of December 14, 2005, by and
among the Company and the buyers party thereto including the original Holder (the "Purchase Agreement"), shall have the
meanings given to such terms in the Purchase Agreement.  

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

	Registration of Transfers.  The Company shall register the transfer of 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 Transfer Agent or 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 of a holder of a Warrant.

	Expiration of Warrant; Notice of Change of Control.

	The portion of this Warrant not previously exercised shall be and become void, no longer exercisable and
of no value at 5:00 p.m., New York City time, on December 19, 2010.

	The term "Change of Control" for purposes of this section shall mean (i) any
consolidation or merger involving the Company pursuant to which the Company's stockholders immediately prior to the consummation
of the consolidation or merger own less than fifty percent (50%) of the voting securities of the surviving entity, or in the event that any
Person acquires more than fifty percent (50%) of the voting securities of the Company pursuant to a tender offer and consummates a
merger or consolidation within 12 months of crossing such fifty percent (50%) threshold, pursuant to which the non-affiliate stockholders
of the Company immediately prior to the consummation of the consolidation or merger no longer own voting securities of the surviving
entity or (ii) the sale of all or substantially all of the assets of the Company.  The Company shall provide at least twenty (20) days prior
written notice of any Change of Control.

	Notwithstanding the foregoing and the provisions of Section 9(c) below, in the event of a Change of
Control, if the Holder has not exercised the Warrant in full prior to the consummation of the Change of Control, then the Company may
terminate the exercisability of this Warrant by paying to the Holder in cash simultaneously with the consummation of the Change of
Control an amount equal to the value of the remaining unexercised portion of this Warrant on the date of such consummation, which
value shall be determined by use of the Black and Scholes Option Pricing Model reflecting (i) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the remaining term of this Warrant as of such date of request and
(ii) an expected volatility equal to the greater of 60% and the 100 day volatility obtained from the HVT function on
Bloomberg.

	Delivery of Warrant Shares.

	Upon delivery of the Form of Election to Purchase (in the form of Exhibit A hereto) (the "Exercise
Notice") to the Company (with the Warrant Shares Exercise Log in the form of Exhibit B hereto) at its address for notice set
forth in Section 13 and (i) upon payment of the Exercise Price multiplied by the number of Warrant Shares that the Holder intends to
purchase hereunder or (ii) upon notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined
in Section 5(e)), the Company shall promptly (but in no event later than three (3) trading days after the Date of Exercise (as defined
herein)) issue and deliver to the Holder electronically through the Depository Trust Corporation, or if unable to do, deliver certificates
for, the Warrant Shares issuable upon such exercise, which Warrant Shares shall be issued under the Registration Statement and shall
be freely tradable on the Principal Market.

A "Date of Exercise" means the date on which the Holder shall have delivered to the Company (i) the
Form of Election to Purchase (with the Warrant Exercise Log attached to it), appropriately completed and duly signed and (ii) (A)
payment of the Exercise Price for the number of Warrant Shares so indicated by the Holder to be purchased or (B) notification to the
Company that this Warrant is being exercised pursuant to a Cashless Exercise.

	If by the fifth Trading day after a Date of Exercise the Company fails to deliver the required number of
Warrant Shares in the manner required pursuant to Section 5(a), then the Holder will have the right to rescind such exercise.

	If by the third Trading day after a Date of Exercise the Company fails to deliver the required number of
Warrant Shares in the manner required pursuant to Section 5(a), and if after such third 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, other than in the case of a Buy-In resulting from the act
or omission of the Holder, 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 by (B) the closing 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, which notice shall include such supporting documentation as
reasonably necessary to substantiate the amounts payable, indicating the amounts payable to the Holder in respect of the Buy-In.

	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 which 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.

(e)If, despite the Company's obligations under the Purchase Agreement and this Warrant, the
Warrant Shares to be issued are not registered and available for issuance pursuant to an effective registration statement, then,
notwithstanding anything contained herein to the contrary, the Holder of this Warrant may, at its election exercised in its sole discretion,
exercise this Warrant in whole or in part and, in lieu of paying the Exercise Price in cash, elect instead to receive upon such exercise
the "Net Number" of shares of Common Stock determined according to the following formula (a
"Cashless Exercise"):

               Net Number = (A x B) - (A x C)

                     B

For purposes of the foregoing formula:

A= the total number of shares with respect to which this Warrant is then being exercised;

B= the greater of the (i) closing price per share of the Common Stock (as reported by the Principal Market) on the
Trading day immediately preceding the date of the Exercise Notice or (ii) the average of the closing prices per share of Common Stock
(as reported by the Principal Market) for the ten (10) Trading days immediately preceding the date of the Exercise Notice ; and

C= the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

	Charges, Taxes and Expenses.  Issuance and delivery of the 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 shares, all of which taxes and expenses shall be paid by the
Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer
involved in the registration of any Warrant Shares or 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.

	Replacement of Warrant.  If this Warrant is mutilated, lost, stolen or destroyed, the Company shall
issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant,
a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and
customary and reasonable indemnity, if requested.  Applicants for a New Warrant under such circumstances shall also comply with
such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may
prescribe.

	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 which are then
issuable and deliverable upon the exercise of this entire Warrant. 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.

	Certain Adjustments.  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.

	Adjustment Upon Issuance of Shares of Common Stock.  If and whenever on or after the
Subscription Date the Company issues or sells, or in accordance with this Section 9 is deemed to have issued or sold, any shares of
Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but
excluding shares of Common Stock deemed to have been issued by the Company in connection with any Excluded Securities (as
defined below) for a consideration per share less than a price (the "Applicable Price") equal to the Exercise Price in effect
immediately prior to such issue or sale or deemed issuance or sale (the foregoing a "Dilutive Issuance"), then immediately
after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount equal to the product of (A) the
Exercise Price in effect immediately prior to such Dilutive Issuance and (B) the quotient determined by dividing (1) the sum
of (I) the product derived by multiplying the Exercise Price in effect immediately prior to such Dilutive Issuance and the number of
Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any, received by
the Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Exercise Price in effect immediately
prior to such Dilutive Issuance by (II) the number of Common Stock Deemed Outstanding immediately after such Dilutive
Issuance.  Upon each such adjustment of the Exercise Price hereunder, the number of Warrant Shares shall be adjusted to the number
of shares of Common Stock determined by multiplying the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares acquirable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by
the Exercise Price resulting from such adjustment.  For purposes of determining the adjusted Exercise Price under this Section 9(a), the
following shall be applicable:

	Issuance of Options.  If the Company in any manner grants any Options and the lowest price per
share for which one share of shares of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise
or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share
of shares of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the
granting or sale of such Option for such price per share.  For purposes of this Section 9(a)(i), the "lowest price per share for which one
share of shares of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such
Convertible Securities" shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company
with respect to any one share of shares of Common Stock upon the granting or sale of the Option, upon exercise of the Option and
upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option.  No further adjustment of
the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock or of such
Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon
conversion, exercise or exchange of such Convertible Securities. 

	Issuance of Convertible Securities.  If the Company in any manner issues or sells any Convertible
Securities and the lowest price per share for which one share of shares of Common Stock is issuable upon the conversion, exercise or
exchange thereof is less than the Applicable Price, then such share of shares of Common Stock shall be deemed to be outstanding and
to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per
share.  For the purposes of this Section 9(a)(ii), the "lowest price per share for which one share of shares of Common Stock is issuable
upon the conversion, exercise or exchange" shall be equal to the sum of the lowest amounts of consideration (if any) received or
receivable by the Company with respect to one share of shares of Common Stock upon the issuance or sale of the Convertible Security
and upon conversion, exercise or exchange of such Convertible Security.  No further adjustment of the Exercise Price or number of
Warrant Shares shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of
such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for
which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 9(a), no further adjustment of
the Exercise Price or number of Warrant Shares shall be made by reason of such issue or sale. 

	Change in Option Price or Rate of Conversion.  If the purchase price provided for in any Options,
the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate
at which any Convertible Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or
decreases at any time, the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be
adjusted to the Exercise Price and the number of Warrant Shares which would have been in effect at such time had such Options or
Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased
conversion rate, as the case may be, at the time initially granted, issued or sold.  For purposes of this Section 9(a)(iii), if the terms of
any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or decreased in the
manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock
deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase
or decrease.  No adjustment pursuant to this Section 9(a) shall be made if such adjustment would result in an increase of the Exercise
Price then in effect or a decrease in the number of Warrant Shares.

	Calculation of Consideration Received.  In case any Option is issued in connection with the issue
or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is
allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $0.01.  If any
shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the
consideration received therefor will be deemed to be the net amount received by the Company therefor.  If any shares of Common
Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration
received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which
case the amount of consideration received by the Company will be the Closing Sale Price of such security on the date of receipt.  If any
shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any
merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such
portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or
Convertible Securities, as the case may be.  The fair value of any consideration other than cash or securities will be determined jointly
by the Company and the Required Holders.  If such parties are unable to reach agreement within ten (10) days after the occurrence of
an event requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined within five (5)
Business Days after the tenth day following the Valuation Event by an independent, reputable appraiser jointly selected by the
Company and the Required Holders.  The determination of such appraiser shall be final and binding upon all parties absent manifest
error and the fees and expenses of such appraiser shall be borne by the Company.

	Record Date.  If the Company takes a record of the holders of shares of Common Stock for the
purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in
Convertible Securities or (B) to subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such
record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or
purchase, as the case may be.

	Definitions.  "Common Stock Deemed Outstanding" means, at any given time, the
number of shares of Common Stock actually outstanding at such time, plus the number of shares of Common Stock deemed to be
outstanding pursuant to Sections 9(a)(i) and 9(a)(ii) hereof regardless of whether the Options or Convertible Securities are actually
exercisable at such time, but excluding any shares of Common Stock owned or held by or for the account of the Company or issuable
upon exercise of the Warrants.  "Convertible Securities" means any stock or securities (other than Options) directly or
indirectly convertible into or exercisable or exchangeable for shares of Common Stock.  "Excluded Securities" means shares
of Common Stock deemed to have been issued or sold by the Company (I) in connection with any employee benefit plan which has
been approved by the Board of Directors of the Company, pursuant to which the Company's securities may be issued to any employee,
officer, director or consultant for services provided to the Company, (II) upon exercise of the Warrants, (III) in connection with any
acquisition by the Company, whether through an acquisition for stock or a merger, of any business, assets or technologies the primary
purpose of which is not to raise equity capital, (IV) pursuant to a bona fide firm commitment underwritten public offering which
generates net proceeds to the Company in excess of $25,000,000 (other than an "at-the-market offering" as defined in Rule 415(a)(4)
under the 1933 Act and "equity lines"), and (V) upon conversion of any Options or Convertible Securities which are outstanding on the
day immediately preceding the Date of Original Issuance, provided that the terms of such Options or Convertible Securities are not
amended, modified or changed on or after the Date of Original Issuance.  "Options" means any rights, warrants or options to
subscribe for or purchase shares of Common Stock or Convertible Securities.

	Until such time as the Company receives any necessary stockholder approval,
including pursuant to Nasdaq Rule 4350(i), no adjustment pursuant to this Section 9(a) shall cause the Exercise Price to be less than
$1.50, as adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction.

	Stock Dividends and Splits.  If the Company, at any time while this Warrant is outstanding, (i) pays
a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of
Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding
shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of
which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding immediately after such event.

	Fundamental Transactions.  Other than in compliance with Section 4(c) hereof, the Company shall
not enter into or be party to a Fundamental Transaction unless (i) the Person formed by or surviving any such Fundamental
Transaction (if other than the Company) or the Person to which such Fundamental Transaction shall have been made assumes all the
obligations of the Company under this Warrant pursuant to written agreements in form and substance reasonably satisfactory to the
Required Holders and approved by the Required Holders prior to such Fundamental Transaction, and including agreements to deliver
to each holder of Warrants in exchange for such Warrants, a security of the Person formed by or surviving any such Fundamental
Transaction (if other than the Company) or the Person to which such Fundamental Transaction shall have been made evidenced by a
written instrument substantially similar in form and substance to the Warrants, including, without limitation, an adjusted exercise price
equal to the value for the shares of Common Stock reflected by the terms of such Fundamental Transaction, and exercisable for a
corresponding number of shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any
limitations on the exercise of this Warrant), if the value so reflected is less than the Exercise Price in effect immediately prior to such
Fundamental Transaction, and (ii) the Company or the Person formed by or surviving any such Fundamental Transaction or to
which such Fundamental Transaction shall have been made is a publicly traded entity whose common stock or equivalent equity
security is quoted on or listed for trading on a Principal Market.  Upon any Fundamental Transaction, the
successor entity to such Fundamental Transaction shall succeed to, and be substituted for (so that from and after the date of such
Fundamental Transaction, the provisions of this Warrant referring to such "Company" shall refer instead to the successor entity or, if so
elected by the Required Holders, by the entity that, directly or indirectly, controls such successor entity), and may exercise every right
and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such
successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be
relieved from its obligations under the Transaction Documents except in the case of a Fundamental Transaction that meets the
requirements of this section.  The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions.
"Fundamental Transaction" means that the Company shall, directly or indirectly, in one or more related transactions, (i)
consolidate or merge with or into (whether or not the Company is the surviving corporation) another Person, or (ii) sell, assign, transfer,
convey or otherwise dispose of all or substantially all of the properties or assets of the Company to another Person, or (iii) allow a
purchase, tender or exchange offer to be made to and accepted by the holders of more than the 50% of the outstanding shares of
Common Stock (not including any shares of Common Stock held by the Person or Persons making or party to, or associated or
affiliated with the Persons making or party to, such purchase, tender or exchange offer), or (iv) enter into a stock purchase agreement
or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with
another Person.  "Required Holders" means the holders of the Warrants representing at least a majority of shares of Common
Stock underlying the Warrants then outstanding.

	Reclassification, Reorganization and Change in Capital Stock.  In addition to and not in
substitution for any other rights hereunder, in case of any reclassification, capital reorganization, or change in the capital stock of the
Company (other than as a result of a stock dividend, subdivision or combination provided for in Section 9(a) above), then the
Company shall make appropriate provision so that the holder of this Warrant shall have the right at any time prior to the expiration of
this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock
and other securities and property receivable in connection with such reclassification, reorganization, or change by a holder of the same
number of Common Stock as were purchasable by the holder of this Warrant immediately prior to such reclassification, reorganization,
or change In any such case appropriate provisions shall be made with respect to the rights and interest of the holder of this Warrant so
that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities and property deliverable
upon exercise hereof, and appropriate adjustments shall be made to the purchase price per share payable hereunder, provided the
aggregate purchase price shall remain the same.

(d) Number of Warrant Shares.  Simultaneously with any adjustment to the Exercise Price
pursuant to paragraphs (a) or (b) of this Section, the number of Warrant Shares that may be purchased upon exercise of this Warrant
shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the
adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such
adjustment.

(e) Calculations.  All calculations under this Section 9 shall be made to the nearest
cent or the nearest 1/100th of a share, as applicable.  The number of shares of Common Stock outstanding at any given time shall not
include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an
issue or sale of Common Stock.

(f) Notice of Adjustments.  Upon the occurrence of each adjustment pursuant to this
Section 9, the Company at its expense will promptly compute such adjustment in accordance with the terms of this Warrant and
prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of
Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such
adjustments and showing in detail the facts upon which such adjustment is based.  Upon written request, the Company will promptly
deliver a copy of each such certificate to the Holder.

(g)Rights of Stockholders.  No holder of this Warrant shall be entitled, as a Warrant holder, to vote
or receive dividends or be deemed the holder of any Common Stock, nor shall anything contained herein be construed to confer upon
the holder of this Warrant, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon
any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise)
or to receive notice of meetings, or to receive subscription rights or otherwise until the Warrant has been exercised and the Common
Stock purchasable upon exercise hereof shall become deliverable as provided herein.

	Payment of Exercise Price.  The Holder shall pay the Exercise Price in cash by delivering
immediately available funds or, if permitted by Section 5(e), through a Cashless Exercise.

	Limitation on Exercise; Beneficial Ownership.  The Company shall not effect the exercise
of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise,
such Person (together with such Person's affiliates) would beneficially own in excess of 9.99% of the shares of Common Stock
outstanding immediately after giving effect to such exercise.  For purposes of the foregoing sentence, the aggregate number of shares
of Common Stock beneficially owned by such Person and its affiliates shall include the number of shares of Common Stock issuable
upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of
Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by
such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the
Company or exercisable for securities of the Company beneficially owned by such Person and its affiliates (including, without limitation,
any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the
limitation contained herein.  Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be
calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended.  For purposes of this Warrant, in
determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common
Stock as reflected in (1) the Company's most recent Form 10-K, Form 10-Q or other public filing with the Securities and Exchange
Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or
the transfer agent of the Company setting forth the number of shares of Common Stock outstanding.  For any reason at any time, upon
the written or oral request of the Holder, the Company shall within one Business Day confirm orally and in any written form (including
email) 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 the
Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was
reported.

	No Fractional Shares.  No fractional shares of Warrant Shares will be issued in connection with
any exercise of this Warrant.  In lieu of any fractional shares which 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 on the Principal Market on the date of
exercise.

	Notices.  Any and all notices or other communications or deliveries hereunder (including without
limitation any Exercise Notice) shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission,
if such notice or communication is delivered via facsimile at the facsimile number specified in this Section prior to 5:00 p.m. (New York
City time) on a Trading day, (ii) the next Trading day after the date of transmission, if such notice or communication is delivered via
facsimile at the facsimile number specified in this Section on a day that is not a Trading day or later than 5:00 p.m. (New York City time)
on any Trading day, (iii) the Trading day following the date of mailing, if sent by nationally recognized overnight courier service, or (iv)

prior to the consummation of the consolidation or merger no longer own voting securities of the surviving entity, or (ii) the
sale of all or substantially all of the assets of the Company to a purchaser which is not an affiliate of the Company.  For the purposes of

issuable upon the exercise of Warrants, and any post-effective amendments and supplements filed or required to be filed to permit any
such disposition.

The term "Securities Act" means the Securities Act of 1933, as amended, as the same shall be in effect at the
time.

The term "Underlying Securities" means any Common Stock or Other Securities issued or issuable upon

	Registration, etc.  The Holder shall have the rights to registration of Underlying Securities issuable upon exercise

Holder (the "Registration Rights Agreement").
	Sale or Exercise Without Registration.  If, at the time of any exercise, transfer or surrender for exchange of a
Warrant or of Underlying Securities previously issued upon the exercise of Warrants, such Warrant or Underlying Securities shall not be
registered under the Securities Act, the Company may require, as a condition of allowing such exercise, transfer or exchange, that the
Holder or transferee of such Warrant or Underlying Securities, as the case may be, furnish to the Company an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such exercise, transfer or exchange may be made without registration under
the Securities Act, provided that the disposition thereof shall at all times be within the control of such Holder or transferee, as the case
may be, and provided further that nothing contained in this Section 2 shall relieve the Company from complying with any request for
registration pursuant to the Registration Rights Agreement.  The first Holder of this Warrant, by acceptance hereof, represents to the
Company that it is acquiring the Warrants for investment and not with a view to the distribution thereof.
	Exercise of Warrant

3.1   Exercise in Full.  Subject to the provisions hereof, this Warrant may be exercised in full by the Holder hereof by surrender
of this Warrant, with the form of subscription at the end hereof duly executed by such Holder, to the Company at its principal office
accompanied by payment, in cash or by certified or official bank check payable to the order of the Company, in the amount obtained by
multiplying the number of shares of Common Stock issuable upon exercise of this Warrant by the Purchase Price per share, after giving
effect to all adjustments through the date of exercise.

3.2   Partial Exercise.  Subject to the provisions hereof, this Warrant may be exercised in part by surrender of this
Warrant in the manner and at the place provided in Section 3.1 except that the amount payable by the Holder upon any partial exercise
shall be the amount obtained by multiplying (a) the number of shares of Common Stock (without giving effect to any adjustment
therein) designated by the Holder in the subscription at the end hereof by (b) the Purchase Price per share.  Upon any such
partial exercise, the Company at its expense will forthwith issue and deliver to or upon the order of the Holder hereof a new Warrant or
Warrants of like tenor, in the name of the Holder hereof or as such Holder (upon payment by such Holder of any applicable transfer
taxes) may request, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock equal (without
giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of such
shares designated by the Holder in the subscription at the end hereof.

3.3   Exercise by Surrender of Warrant or Shares of Common Stock.  In addition to the method of payment set forth in
Sections 3.1 and 3.2 and in lieu of any cash payment required thereunder, the Holder(s) of the Warrants shall have the right at any time
and from time to time to exercise the Warrants in full or in part by surrendering shares of Common Stock, this Warrant or other
securities issued by the Company in the manner and at the place specified in Section 3.1 as payment of the aggregate Purchase Price
per share for the Warrants to be exercised.  The number of Warrants or shares of Common Stock to be surrendered in payment of the
aggregate Purchase Price for the Warrants to be exercised shall be determined by multiplying the number of Warrants to be exercised
by the Purchase Price per share, and then dividing the product thereof by an amount equal to the Market Price (as defined below) .
The number of shares of Common Stock or such other securities to be surrendered in payment of the aggregate Purchase Price for the
Warrants to be exercised shall be determined in accordance with the preceding sentence as if the other securities had been converted
into Common Stock immediately prior to exercise or, in the case the Company has issued other securities which are not convertible into
Common Stock, at the Market Price thereof.  

3.4   Definition of Market Price.  As used herein, the phrase "Market Price" at any date shall be
deemed to be (i) if the principal trading market for such securities is an exchange, the average of the last reported sale prices per
share for the last five previous trading days in which a sale was reported, as officially reported on any consolidated tape, (ii) if the
principal market for such securities is the over-the-counter market, the average of the high bid prices per share on such trading days as
set forth by Nasdaq or, (iii) if the security is not quoted on Nasdaq, the average of the high bid prices per share on such trading
days as set forth in the National Quotation Bureau sheet listing such securities for such days.  Notwithstanding the foregoing, if there is
no reported closing price or high bid price, as the case may be, on any of the ten trading days preceding the event requiring a
determination of Market Price hereunder, then the Market Price shall be determined in good faith by resolution of the Board of Directors
of the Company, based on the best information available to it.  

3.5   Company to Reaffirm Obligations.  The Company will, at the time of any exercise of this Warrant, upon the
request of the Holder hereof, acknowledge in writing its continuing obligation to afford to such Holder any rights (including, without
limitation, any right to registration of the Underlying Securities) to which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of this Warrant, provided that if the Holder of this Warrant shall fail to make any such request,
such failure shall not affect the continuing obligation of the Company to afford such Holder any such rights.

3.6   Certain Exercises.  If an exercise of a Warrant or Warrants is to be made in connection with a registered public
offering or sale of the Company, such exercise may, at the election of the Holder, be conditioned on the consummation of the public
offering or sale of the Company, in which case such exercise shall not be deemed effective until the consummation of such
transaction.

	Delivery of Stock Certificates, etc., on Exercise.  As soon as practicable after the exercise of this Warrant in full
or in part, and in any event within three business days thereafter, the Company at its own expense (including the payment by it of any
applicable issue taxes) will cause to be issued in the name of and delivered to the Holder hereof, or as such Holder (upon payment by
such Holder of any applicable transfer taxes) may direct, a certificate or certificates for the number of fully paid and non-assessable
shares of Common Stock or Other Securities to which such Holder shall be entitled upon such exercise, plus, in lieu of any fractional
share to which such Holder would otherwise be entitled, cash equal to such fraction multiplied by the then current Market Price of one
full share.
	Subdivisions, Combinations and Other Issuances.  If the Company shall at any time prior to the expiration of this
Warrant subdivide the Underlying Securities, by split-up or otherwise, or combine its Underlying Securities, or issue additional shares of
its Underlying Securities as a dividend, the number of Underlying Securities issuable on the exercise of this Warrant shall forthwith be
proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination.
Appropriate adjustments shall also be made to the Purchase Price payable per share, but the aggregate Purchase Price payable for the
total number of Underlying Securities purchasable under this Warrant (as adjusted) shall remain the same.  Any adjustment under this
Section 5 shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of
the record date of such dividend, or in the event that no record date is fixed, upon the making of such dividend.
	Reclassification, Reorganization and Consolidation.  In case of any reclassification, capital reorganization, or
change in the capital stock of the Company (other than as a result of a subdivision, combination, or stock dividend provided for in
Section 5 above), then the Company shall make appropriate provision so that the holder of this Warrant shall have the right at
any time prior to the expiration of this Warrant to purchase, at a total price equal to that payable upon the exercise of this Warrant, the
kind and amount of shares of stock and other securities and property receivable in connection with such reclassification, reorganization,
or change by a holder of the same number of Underlying Securities as were purchasable by the holder of this Warrant immediately prior
to such reclassification, reorganization, or change In any such case appropriate provisions shall be made with respect to the rights and
interest of the holder of this Warrant so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or
other securities and property deliverable upon exercise hereof, and appropriate adjustments shall be made to the purchase price per
share payable hereunder, provided the aggregate purchase price shall remain the same.
	Further Assurances.  The Company will take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and non-assessable shares of stock upon the exercise of all Warrants from time to
time outstanding.
	Certificate as to Adjustments.  In each case of any adjustment or readjustment in the shares of Common Stock
(or Other Securities) issuable upon the exercise of the Warrants, the Company at its expense will promptly compute such adjustment or
readjustment in accordance with the terms of the Warrants and prepare a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based, and the number of shares of Common Stock
outstanding or deemed to be outstanding.  The Company will forthwith mail a copy of each such certificate to each Holder.
	Rights of Stockholders.  No holder of this Warrant shall be entitled, as a Warrant holder, to vote or receive
dividends or be deemed the holder of any Underlying Securities, nor shall anything contained herein be construed to confer upon the
holder of this Warrant, as such, any of the rights of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger, conveyance,
or otherwise) or to receive notice of meetings, or to receive subscription rights or otherwise until the Warrant has been exercised and
the Underlying Securities purchasable upon exercise hereof shall become deliverable as provided herein.
	Reservation of Stock, etc., Issuable on Exercise of Warrants.  The Company will at all times reserve and keep
available, solely for issuance and delivery upon the exercise of the Warrants, all shares of Common Stock (or Other Securities) from
time to time issuable upon the exercise of the Warrants.
	Listing on Securities Exchanges.  In furtherance and not in limitation of any other provision of this Warrant, if the
Company at any time shall list any Common Stock on any national securities exchange and shall register such Common Stock under
the Exchange Act, the Company will, at its expense, simultaneously list on such exchange or Nasdaq, upon official notice of issuance
upon the exercise of the Warrants, and maintain such listing of all shares of Common Stock from time to time issuable upon the
exercise of the Warrants; and the Company will so list on any national securities exchange or Nasdaq, will so register and will maintain
such listing of, any Other Securities if and at the time that any securities of like class or similar type shall be listed on such national
securities exchange or Nasdaq by the Company.
	Exchange of Warrants.  Subject to the provisions of Section 2 hereof, upon surrender for exchange of any
Warrant, properly endorsed, to the Company, as soon as practicable (and in any event within three business days) the Company at its
own expense will issue and deliver to or upon the order of the Holder thereof a new Warrant or Warrants of like tenor, in the name of
such Holder or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant or Warrants so
surrendered.
	Replacement of Warrants.  Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of any Warrant and, in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, upon surrender and cancellation of
such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.
	Remedies.  The Company stipulates that the remedies at law of the Holder of this Warrant in the event of any
default or threatened default by the Company in the performance of or compliance with any of the terms of this Warrant are not and will
not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms hereof or otherwise.
	Negotiability, etc.  Subject to Section 2 above, this Warrant is issued upon the following terms, to all of which
each Holder or owner hereof by the taking hereof consents and agrees:
