                        WARRANT TO PURCHASE COMMON STOCK
                              EXPIRES MAY 27, 2010

      This warrant (this "WARRANT") certifies that, for good and valuable
consideration, _______________ (the "HOLDER") is entitled to purchase from A-Fem
Medical Corporation, a Nevada corporation (the "COMPANY"),
___________________________ (________) fully paid and nonassessable shares of
Common Stock, par value $0.01 per share ("COMMON STOCK"), of the Company (as
adjusted pursuant to Section 3) (the "WARRANT SHARES") at a price per share
equal to Eighty-five Cents ($0.85) (as adjusted pursuant to Section 3) (the
"EXERCISE PRICE", upon the terms and subject to the conditions hereinafter set
forth.

1. EXERCISE; PAYMENT.

         (A) Exercise Period. This Warrant may be exercised in whole or part by
     the Holder during the term (as set forth in Section 7) and in compliance
     with the provisions of this Warrant at any time after the date of issuance
     set forth above (the "WARRANT DATE"), by the surrender of this Warrant
     (with the notice of exercise form attached hereto as Exhibit A (the "NOTICE
     OF EXERCISE") duly executed) at the principal office of the Company. If
     this Warrant shall have been exercised in part, the Company shall, at the
     time of delivery of the certificate or certificates representing Warrant
     Shares, deliver to the Holder a new Warrant evidencing the rights of the
     Holder to purchase the unpurchased shares of Common Stock called for by
     this Warrant, which new Warrant shall in all other respects be identical
     with this Warrant, or at the request of the Holder, appropriate notation
     may be made on this Warrant and the same returned to the Holder.

         (B) Exercise. Upon exercise of this Warrant, the Holder shall pay to
     the Company an amount equal to the product of (x) the Exercise Price
     multiplied by (y) the total number of

<PAGE>

Warrant Shares purchased pursuant to this Warrant, by wire transfer or cashier's
check payable to the order of the Company. The Holder shall be deemed to have
become the holder of record of, and shall be treated for all purposes as the
record holder of, the Warrant Shares represented thereby (and such Warrant
Shares shall be deemed to have been issued) immediately prior to the close of
business on the date upon which this Warrant is exercised. (C) Stock
Certificates. In the event of the exercise of this Warrant, certificates for the
Warrant Shares so purchased shall be delivered to the Holder promptly after
exercise but in no event more than ten (10) business days after such exercise.

2. STOCK FULLY PAID; RESERVATION OF SHARES. All of the Warrant Shares issuable
upon the exercise of this Warrant will, upon issuance in accordance with the
terms of this Warrant, be fully paid and nonassessable, and free from all
preemptive rights, rights of first refusal or first offer, taxes, liens and
charges with respect to the issuance thereof. During the period within which the
rights represented by this Warrant may be exercised, the Company shall at all
times have authorized and reserved for issuance a sufficient number of shares of
its Common Stock to provide for the exercise of this Warrant.

3. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The number and kind of
Warrant Shares purchasable upon the exercise of this Warrant and the Exercise
Price payable therefore shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

         (A) Reclassification, Consolidation or Reorganization. In case of any
     reclassification of the Common Stock (other than a change in par value, or
     as a result of a subdivision or combination), or in case of any
     consolidation or merger of the Company with or into another corporation
     (other than a Change of Control, as defined below) (any of which is a
     "REORGANIZATION TRANSACTION"), the Company, or such successor corporation
     as the case may be, shall execute a new warrant, providing that the Holder
     shall have the right to exercise such new warrant, and procure upon such
     exercise and payment of the same aggregate Exercise Price, in lieu of the
     Warrant Shares theretofore issuable upon exercise of this Warrant, the kind
     and amount of shares of stock, other securities, money and property as
     would be payable for the Warrant Shares issuable upon exercise of this
     Warrant as if such Warrant Shares were outstanding immediately prior to the
     consummation of the Reorganization Transaction. For purposes of this
     Warrant, the term "Change of Control" shall mean (i) any acquisition of the
     Company by means of merger, acquisition, or other form of corporate
     reorganization in which outstanding shares of the Company are exchanged for
     securities or other consideration issued, or caused to be issued, by the
     acquiring corporation or its subsidiary or parent (other than a
     reincorporation transaction or change of domicile) and pursuant to which
     the holders of the outstanding voting securities of the Company immediately
     prior to such consolidation, merger or other transaction fail to hold
     equity securities representing a majority of the voting power of the
     Company or surviving entity immediately following such consolidation,
     merger or other transaction (excluding voting securities of the acquiring
     corporation held by such holders prior to such transaction) or (ii) a sale
     of all or substantially all of the assets of the Company.

<PAGE>

         (B) Stock Splits, Dividends and Combinations. In the event that the
     Company shall at any time subdivide the outstanding shares of Common Stock,
     or shall issue a stock dividend on its outstanding shares of Common Stock,
     the number of Warrant Shares issuable upon exercise of this Warrant
     immediately prior to such subdivision or to the issuance of such stock
     dividend shall be proportionately increased, and the Exercise Price shall
     be proportionately decreased, and in the event that the Company shall at
     any time combine the outstanding shares of Common Stock, the number of
     Warrant Shares issuable upon exercise of this Warrant immediately prior to
     such combination shall be proportionately decreased, and the Exercise Price
     shall be proportionately increased, effective at the close of business on
     the date of such subdivision, stock dividend or combination, as the case
     may be.

         (C) Adjustment Upon Issuance of Shares of Common Stock Below Exercise
     Price.

             (I) If the Company, at any time or from time to time, issues or
             sells any Additional Shares of Common Stock (as defined below),
             other than as provided in the foregoing subsections of this Section
             3, for a price per share (which, in the case of options, warrants,
             convertible securities or other rights, includes the amounts paid
             therefore plus the exercise price, conversion price or other such
             amounts payable thereunder) that is less than the then applicable
             Exercise Price, then and in each such case, the then applicable
             Exercise Price shall automatically be reduced as of the opening of
             business on the date of such issue or sale, to a price determined
             by multiplying the Exercise Price by a fraction (i) the numerator
             of which shall be (A) the number of shares of Common Stock deemed
             outstanding (as determined below) immediately prior to such issue
             or sale, plus (B)the number of shares of Common Stock which the
             aggregate consideration received by the Company for the total
             number of Additional Shares of Common Stock so issued would
             purchase at such Exercise Price, and (ii) the denominator of which
             shall be the number of shares of Common Stock deemed outstanding
             (as defined below) immediately prior to such issue or sale plus the
             total number of Additional Shares of Common Stock so issued;
             provided, however, that upon the expiration or other termination of
             options, warrants, or other rights to purchase or acquire shares of
             Common Stock, and upon the expiration or termination of the right
             to convert or exchange convertible or exchangeable securities
             (whether by reason of redemption or otherwise), if any thereof
             shall not have been exercised, converted or exchanged, as
             applicable, the number of shares of Common Stock deemed to be
             outstanding pursuant to this Section 3(c) shall be reduced by the
             number of shares as to which options, warrants, and rights to
             purchase or acquire shares of Common Stock shall have expired or
             terminated unexercised, and as to which conversion or exchange
             rights shall have expired or terminated unexercised, and such
             number of shares shall no longer be deemed to be outstanding; and
             the Exercise Price then in effect shall forthwith be readjusted and
             thereafter be the price that it would have been had adjustment been
             made on the basis of the issuance only of the shares of Common
             Stock actually issued. For purposes of the preceding sentence, the
             number of shares of Common Stock deemed to be outstanding as of a
             given date shall be the sum of (A) the number of shares of Common
             Stock actually outstanding, (B) the number of Shares for which the
             Warrant could be exercised on the day immediately preceding the
             given date, and

<PAGE>

             (C) the number of shares of Common Stock which could be obtained
             through the exercise or conversion of all other rights, options and
             convertible securities outstanding on the day immediately preceding
             the given date. "ADDITIONAL SHARES OF COMMON STOCK" shall mean all
             shares of Common Stock, and all options, warrants, convertible
             securities or other rights to purchase or acquire shares of Common
             Stock, issued by the Company other than (A) shares of Common Stock
             and/or options, warrants or other Common Stock purchase rights,
             where such options, warrants or other rights are issued both (i)
             with exercise prices per share of Common Stock at the then-current
             fair market value of a share of Common Stock, as determined in good
             faith by the Board of Directors of the Company, and (ii) to
             employees, officers or directors of, or consultants to, the Company
             or any subsidiary pursuant to stock purchase or stock option plans
             or other arrangements that are approved by the Company's Board of
             Directors and (B) shares of Common Stock issued pursuant to the
             exercise of options, warrants or convertible securities outstanding
             as of the date hereof.

             (ii) In the event that the exercise price, conversion price,
             purchase price or other price at which shares of Common Stock are
             purchasable pursuant to any options, warrants, convertible
             securities or other rights to purchase or acquire Common Stock is
             reduced at any time or from time to time (other than under or by
             reason of provisions designed to protect against dilution), then,
             upon such reduction becoming effective, the Exercise Price then in
             effect hereunder shall forthwith be decreased to such Exercise
             Price as would have been obtained had the adjustments made and
             required under this Section 3 upon the issuance of such options,
             warrants, convertible securities or other rights been made upon the
             basis of (and the total consideration received therefore) (A) the
             issuance of the number of shares of Common Stock theretofore
             actually delivered upon the exercise, conversion or exchange of
             such options, warrants, convertible securities or other rights, (B)
             the issuance of all of the Common Stock and all other options,
             warrants, convertible securities and other rights to purchase or
             acquire Common Stock issued after the issuance of the modified
             options, warrants, convertible securities or other rights, and (C)
             the original issuance at the time of the reduction of any such
             options, warrants, convertible securities or other rights then
             still outstanding.

             (iii) In no event shall an adjustment under this Section 3(c) be
             made if it would result in an increase in the then applicable
             Exercise Price.

      (d) Notice of Corporate Action. If at any time (i) the Company shall take
a record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend (other than a cash dividend payable out of earnings or earned
surplus legally available for the payment of dividends under the laws of State
of Nevada) or other distribution, or any right to subscribe for or purchase any
evidences of its indebtedness, any shares of stock of any class or any other
securities or property, or to receive any other right; (ii) there shall be any
capital reorganization of the Company, any reclassification or recapitalization
of the capital stock of the Company or any consolidation or merger of the
Company with, or any sale, transfer or other disposition of all or substantially
all the property, assets or business of the Company to, another corporation; or
(iii) there shall be a voluntary or involuntary

<PAGE>

dissolution, liquidation or winding up of the Company, then, in any one or more
of such cases, the Company shall give to the Holder (i) at least 10 business
days prior written notice of the date on which a record date shall be selected
for such dividend, distribution or right or for determining rights to vote in
respect of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, and (ii) in
the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 10
business days prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause also shall specify (i) the
date on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to the
Holder at the last address of the Holder appearing on the books of the Company
and delivered in accordance with Section 12(d).

4. REDEMPTION. This Warrant may be redeemed by the Company at a price of ONE
CENT ($.01) per Warrant Share on ten (10) days' notice to the Holder (the
"NOTICE") if (i) the closing bid price of the Company's Common Stock exceeds ONE
DOLLAR AND SEVENTY CENTS ($1.70) for twenty (20) consecutive trading days and

effective by the Securities and Exchange Commission and such registration

      (A) EXEMPT TRANSACTION; RESTRICTED SECURITIES. The Holder understands that
this Warrant is being offered and sold in reliance on one or more exemptions
from registration provided for under the Securities Act, and that the Company's

representations and warranties set forth in this Warrant. The Holder understands
that this Warrant and the Warrant Shares are "restricted securities" as such
term is defined in Rule 144 promulgated under the Securities Act {"Rule 144").
The Holder understands that the Holder may resell the Warrant Shares pursuant to

this Warrant for investment for the Holder's own account, not as nominee or
agent, for investment and not with a view to, or for resale in connection with,
any distribution or public offering thereof within the meaning of the Securities
Act. The Holder is an "accredited investor" within the meaning of the Securities
Act. The Holder has the full right, power, authority and capacity to enter into
and perform this Warrant and the terms of this Warrant constitute valid and
binding obligations of the Holder enforceable in accordance with its terms,
except as the same may be limited by equitable principles and by bankruptcy,
insolvency, moratorium, and other laws of general application affecting the
enforcement of creditors' rights.

      (C) KNOWLEDGE AND EXPERIENCE. The Holder has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of the Holder's investment in this Warrant and has the ability to bear the
economic risks of such investment.

      (D) DOMICILE. The Holder is a bona fide resident and domiciliary (not a
temporary or transient resident) of the jurisdiction indicated on the signature
page to this Warrant and the Holder has no present intention of becoming a
resident of any other state or jurisdiction.

the Securities Act is delivered or deemed delivered to the purchaser of such
Warrant Shares, (ii) if such holder satisfies the requirements of Rule 144(k)
under the Securities Act or (iii) if such holder provides the Company with an

securities," as such term is defined in Rule 144 under the Securities Act.

with any exercise of this Warrant, but in lieu of such fractional shares the
Company shall make a cash payment therefore upon the basis of the Exercise Price
then in effect.

receive dividends or be deemed the holder of Warrant Shares or any other

No. W052005-CON-1
                                                        ISSUED: NOVEMBER 8, 2005

                        WARRANT TO PURCHASE COMMON STOCK
                            Expires November 8, 2010

         This warrant (this "Warrant") certifies that, for good and valuable
consideration, BURNHAM HILL PARTNERS (the "Holder"), is entitled to purchase
from QuantRx Biomedical Corporation, a Nevada corporation (the "Company"), ONE
HUNDRED THOUSAND (100,000) fully paid and nonassessable shares of Common Stock,
par value $0.01 per share ("Common Stock"), of the Company (as adjusted pursuant
to Section 3) (the "Warrant Shares") at a price per share equal to TWO DOLLARS
($2.00) (as adjusted pursuant to Section 3) (the "Exercise Price"), upon the
terms and subject to the conditions hereinafter set forth.

1.   EXERCISE; PAYMENT.

         (a)  Exercise Period. This Warrant may be exercised in whole or part by
     the Holder during the term (as set forth in Section 7) and in compliance
     with the provisions of this Warrant at any time after the date of issuance
     set forth above (the "Warrant Date"), by the surrender of this Warrant
     (with the notice of exercise form attached hereto as Exhibit A (the "Notice
     of Exercise") duly executed) at the principal office of the Company. If
     this Warrant shall have been exercised in part, the Company shall, at the
     time of delivery of the certificate or certificates representing Warrant
     Shares, deliver to the Holder a new Warrant evidencing the rights of the
     Holder to purchase the unpurchased shares of Common Stock called for by
     this Warrant, which new Warrant shall in all other respects be identical
     with this Warrant, or at the request of the Holder, appropriate notation
     may be made on this Warrant and the same returned to the Holder.

         (b)  Exercise. Upon exercise of this Warrant, the Holder shall pay to
     the Company an amount equal to the product of (x) the Exercise Price
     multiplied by (y) the total number of Warrant Shares purchased pursuant to
     this Warrant, by wire transfer or cashier's check

<PAGE>

     payable to the order of the Company. The Holder shall be deemed to have
     become the holder of record of, and shall be treated for all purposes as
     the record holder of, the Warrant Shares represented thereby (and such
     Warrant Shares shall be deemed to have been issued) immediately prior to
     the close of business on the date upon which this Warrant is exercised.

         (c)  Cashless Exercise. Notwithstanding any provisions herein to the
     contrary and commencing one (1) year following the Warrant Date, if the per
     share market value of one share of Common Stock is greater than the
     Exercise Price (at the date of calculation as set forth below) and a
     registration statement under the Securities Act of 1933, as amended (the
     "Securities Act") providing for the resale of the Warrant Shares is not
     effective at the time of exercise of this Warrant, 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 Company together with the properly endorsed
     Notice in which event the Company shall issue to the Holder a number of
     shares of Common Stock computed using the following formula:

                  X = Y - (A)(Y)
                          ------
                             B

     Where        X =

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

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

                  A =      the Exercise Price.

                  B =      the per share market value of one share of Common
                           Stock.

         (d)  Stock Certificates. In the event of the exercise of this Warrant,
     certificates for the Warrant Shares so purchased shall be delivered to the
     Holder promptly after exercise but in no event more than ten (10) business
     days after such exercise.

2. STOCK FULLY PAID; RESERVATION OF SHARES. All of the Warrant Shares issuable
upon the exercise of this Warrant will, upon issuance in accordance with the
terms of this Warrant, be fully paid and nonassessable, and free from all
preemptive rights, rights of first refusal or first offer, taxes, liens and
charges with respect to the issuance thereof. During the period within which the
rights represented by this Warrant may be exercised, the Company shall at all
times have authorized and reserved for issuance a sufficient number of shares of
its Common Stock to provide for the exercise of this Warrant.

3. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The number and kind of
Warrant Shares purchasable upon the exercise of this Warrant and the Exercise
Price payable therefor shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

                                       2
<PAGE>

         (a)  Reclassification, Consolidation or Reorganization. In case of any
     reclassification of the Common Stock (other than a change in par value, or
     as a result of a subdivision or combination), or in case of any
     consolidation or merger of the Company with or into another corporation
     (other than a Change of Control, as defined below) (any of which is a
     "Reorganization Transaction"), the Company, or such successor corporation
     as the case may be, shall execute a new warrant, providing that the Holder
     shall have the right to exercise such new warrant, and procure upon such
     exercise and payment of the same aggregate Exercise Price, in lieu of the
     Warrant Shares theretofore issuable upon exercise of this Warrant, the kind
     and amount of shares of stock, other securities, money and property as
     would be payable for the Warrant Shares issuable upon exercise of this
     Warrant as if such Warrant Shares were outstanding immediately prior to the
     consummation of the Reorganization Transaction. For purposes of this
     Warrant, the term "Change of Control" shall mean (i) any acquisition of the
     Company by means of merger, acquisition, or other form of corporate
     reorganization in which outstanding shares of the Company are exchanged for
     securities or other consideration issued, or caused to be issued, by the
     acquiring corporation or its subsidiary or parent (other than a
     reincorporation transaction or change of domicile) and pursuant to which
     the holders of the outstanding voting securities of the Company immediately
     prior to such consolidation, merger or other transaction fail to hold
     equity securities representing a majority of the voting power of the
     Company or surviving entity immediately following such consolidation,
     merger or other transaction (excluding voting securities of the acquiring
     corporation held by such holders prior to such transaction) or (ii) a sale
     of all or substantially all of the assets of the Company.

         (b)  Stock Splits, Dividends and Combinations. In the event that the
     Company shall at any time subdivide the outstanding shares of Common Stock,
     or shall issue a stock dividend on its outstanding shares of Common Stock,
     the number of Warrant Shares issuable upon exercise of this Warrant
     immediately prior to such subdivision or to the issuance of such stock
     dividend shall be proportionately increased, and the Exercise Price shall
     be proportionately decreased, and in the event that the Company shall at
     any time combine the outstanding shares of Common Stock, the number of
     Warrant Shares issuable upon exercise of this Warrant immediately prior to
     such combination shall be proportionately decreased, and the Exercise Price
     shall be proportionately increased, effective at the close of business on
     the date of such subdivision, stock dividend or combination, as the case
     may be.

         (c)  Adjustment Upon Issuance of Shares of Common Stock Below Exercise
     Price.

              (i)  If the Company, at any time or from time to time, issues or
         sells any Additional Shares of Common Stock (as defined below), other
         than as provided in the foregoing subsections of this Section 3, for a
         price per share (which, in the case of options, warrants, convertible
         securities or other rights, includes the amounts paid therefor plus the
         exercise price, conversion price or other such amounts payable
         thereunder) that is less than the then applicable Exercise Price, then
         and in each such case, the then applicable Exercise Price shall
         automatically be reduced as of the opening of business on the date of
         such issue or sale, to a price determined by multiplying the Exercise
         Price by a fraction (i) the numerator of which shall be (A) the number
         of shares of Common Stock deemed outstanding (as determined below)
         immediately prior to such issue or sale, plus (B) the

                                       3
<PAGE>

         number of shares of Common Stock which the aggregate consideration
         received by the Company for the total number of Additional Shares of
         Common Stock so issued would purchase at such Exercise Price, and (ii)
         the denominator of which shall be the number of shares of Common Stock
         deemed outstanding (as defined below) immediately prior to such issue
         or sale plus the total number of Additional Shares of Common Stock so
         issued; provided, however, that upon the expiration or other
         termination of options, warrants, or other rights to purchase or
         acquire shares of Common Stock, and upon the expiration or termination
         of the right to convert or exchange convertible or exchangeable
         securities (whether by reason of redemption or otherwise), if any
         thereof shall not have been exercised, converted or exchanged, as
         applicable, the number of shares of Common Stock deemed to be
         outstanding pursuant to this Section 3(c) shall be reduced by the
         number of shares as to which options, warrants, and rights to purchase
         or acquire shares of Common Stock shall have expired or terminated
         unexercised, and as to which conversion or exchange rights shall have
         expired or terminated unexercised, and such number of shares shall no
         longer be deemed to be outstanding; and the Exercise Price then in
         effect shall forthwith be readjusted and thereafter be the price that
         it would have been had adjustment been made on the basis of the
         issuance only of the shares of Common Stock actually issued. For
         purposes of the preceding sentence, the number of shares of Common
         Stock deemed to be outstanding as of a given date shall be the sum of
         (A) the number of shares of Common Stock actually outstanding, (B) the
         number of Shares for which the Warrant could be exercised on the day
         immediately preceding the given date, and (C) the number of shares of
         Common Stock which could be obtained through the exercise or conversion
         of all other rights, options and convertible securities outstanding on
         the day immediately preceding the given date. "Additional Shares of
         Common Stock" shall mean all shares of Common Stock, and all options,
         warrants, convertible securities or other rights to purchase or acquire
         shares of Common Stock, issued by the Company other than (A) shares of
         Common Stock and/or options, warrants or other Common Stock purchase
         rights, where such options, warrants or other rights are issued both
         (i) with exercise prices per share of Common Stock at the then-current
         fair market value of a share of Common Stock, as determined in good
         faith by the Board of Directors of the Company, and (ii) to employees,
         officers or directors of, or consultants to, the Company or any
         subsidiary pursuant to stock purchase or stock option plans or other
         arrangements that are approved by the Company's Board of Directors and
         (B) shares of Common Stock issued pursuant to the exercise of options,
         warrants or convertible securities outstanding as of the date hereof.

              (ii) In the event that the exercise price, conversion price,
         purchase price or other price at which shares of Common Stock are
         purchasable pursuant to any options, warrants, convertible securities
         or other rights to purchase or acquire Common Stock is reduced at any
         time or from time to time (other than under or by reason of provisions
         designed to protect against dilution), then, upon such reduction
         becoming effective, the Exercise Price then in effect hereunder shall
         forthwith be decreased to such Exercise Price as would have been
         obtained had the adjustments made and required under this Section 3
         upon the issuance of such

                                       4
<PAGE>

         options, warrants, convertible securities or other rights been made
         upon the basis of (and the total consideration received therefor) (A)
         the issuance of the number of shares of Common Stock theretofore
         actually delivered upon the exercise, conversion or exchange of such
         options, warrants, convertible securities or other rights, (B) the
         issuance of all of the Common Stock and all other options, warrants,
         convertible securities and other rights to purchase or acquire Common
         Stock issued after the issuance of the modified options, warrants,
         convertible securities or other rights, and (C) the original issuance
         at the time of the reduction of any such options, warrants, convertible
         securities or other rights then still outstanding.

              (iii)In no event shall an adjustment under this Section 3(c) be
         made if it would result in an increase in the then applicable Exercise
         Price.

         (d)  Notice of Corporate Action. If at any time (i) the Company shall
     take a record of the holders of its Common Stock for the purpose of
     entitling them to receive a dividend (other than a cash dividend payable
     out of earnings or earned surplus legally available for the payment of
     dividends under the laws of State of Nevada) or other distribution, or any
     right to subscribe for or purchase any evidences of its indebtedness, any
     shares of stock of any class or any other securities or property, or to
     receive any other right; (ii) there shall be any capital reorganization of
     the Company, any reclassification or recapitalization of the capital stock
     of the Company or any consolidation or merger of the Company with, or any
     sale, transfer or other disposition of all or substantially all the
     property, assets or business of the Company to, another corporation; or
     (iii) there shall be a voluntary or involuntary dissolution, liquidation or
     winding up of the Company, then, in any one or more of such cases, the
     Company shall give to the Holder (i) at least 10 business days prior
     written notice of the date on which a record date shall be selected for
     such dividend, distribution or right or for determining rights to vote in
     respect of any such reorganization, reclassification, merger,
     consolidation, sale, transfer, disposition, dissolution, liquidation or
     winding up, and (ii) in the case of any such reorganization,
     reclassification, merger, consolidation, sale, transfer, disposition,
     dissolution, liquidation or winding up, at least 10 business days prior
     written notice of the date when the same shall take place. Such notice in
     accordance with the foregoing clause also shall specify (i) the date on
     which any such record is to be taken for the purpose of such dividend,
     distribution or right, the date on which the holders of Common Stock shall
     be entitled to any such dividend, distribution or right, and the amount and
     character thereof, and (ii) the date on which any such reorganization,
     reclassification, merger, consolidation, sale, transfer, disposition,
     dissolution, liquidation or winding up is to take place and the time, if
     any such time is to be fixed, as of which the holders of Common Stock shall
     be entitled to exchange their shares of Common Stock for securities or
     other property deliverable upon such reorganization, reclassification,
     merger, consolidation, sale, transfer, disposition, dissolution,
     liquidation or winding up. Each such written notice shall be sufficiently
     given if addressed to the Holder at the last address of the Holder
     appearing on the books of the Company and delivered in accordance with
     Section 12(d).

                                       5

4. REDEMPTION. This Warrant may be redeemed by the Company at a price of One
Cent ($.01) per Warrant Share on ten (10) days' notice to the Holder (the

Dollar and Seventy Cents ($1.70) for twenty (20) consecutive trading days and
(ii) a registration statement covering the Warrant Shares has been declared
effective by the Securities and Exchange Commission and such registration
statement remains effective thirty (30) days prior to the date of the notice.

5.   TRANSFER OF WARRANT AND RESALE OF WARRANT SHARES.

         (a)  This Warrant may only be transferred in compliance with federal
     and state securities laws.

         (b)  At the time of the surrender of this Warrant in connection with
     any transfer of this Warrant or the resale of the Warrant Shares, the
     Company may require, as a condition of allowing such transfer (i) that the
     Holder or transferee of this Warrant or the Warrant Shares as the case may
     be, furnish to the Company a written opinion of counsel that is reasonably
     acceptable to the Company to the effect that such transfer may be made
     without registration under the Securities Act or qualification under any
     state securities laws, (ii) that the Holder or transferee execute and
     deliver to the Company an investment representation letter in form and
     substance acceptable to the Company containing among other provisions
     representations and warranties similar to those set forth in Section 6 and
     (iii) that the transferee be an "accredited investor" as defined in Rule
     501(a) promulgated under the Securities Act. Transfer of this Warrant and
     all rights hereunder, in whole or in part, in accordance with the foregoing
     provisions, shall be registered on the books of the Company to be
     maintained for such purpose, upon surrender of this Warrant at the
     principal office of the Company or the office or agency designated by the
     Company, together with a written assignment of this Warrant substantially
     in the form of Exhibit B hereto duly executed by the Holder or its
     attorney-in-fact and funds sufficient to pay any transfer taxes payable
     upon the making of such transfer. Upon such surrender and, if required,
     such payment, the Company shall execute and deliver a new Warrant or
     Warrants in the name of the assignee or assignees and in the denomination
     specified in such instrument of assignment, and shall issue to the Holder a
     new warrant evidencing the portion of this Warrant not so assigned, and
     this Warrant shall be deemed cancelled. This Section 5 shall survive the
     exercise or expiration of the Warrant.

6.   REPRESENTATIONS AND WARRANTIES OF HOLDER.

         (a)  Exempt Transaction; Restricted Securities. The Holder understands
     that this Warrant is being offered and sold in reliance on one or more
     exemptions from registration provided for under the Securities Act, and
     that the Company's reliance upon such exemptions is predicated, in part,
     upon the Holder's representations and warranties set forth in this Warrant.
     The Holder understands that this Warrant and the Warrant Shares are
     "restricted securities" as such term is defined in Rule 144 promulgated
     under the Securities Act ("Rule 144"). The Holder understands that the
     Holder may resell the Warrant Shares pursuant to Rule 144 only after the
     satisfaction of certain requirements, including the requirement that the
     Warrant Shares be held for at least one year prior to resale.

     and other laws of general application affecting the enforcement of
     creditors' rights.

         (c)  KNOWLEDGE AND EXPERIENCE. The Holder has such knowledge and
     experience in financial and business matters as to be capable of evaluating
     the merits and risks of the Holder's investment in this Warrant and has the
     ability to bear the economic risks of such investment.

         (d)  DOMICILE. The Holder is a bona fide resident and domiciliary (not
     a temporary or transient resident) of the jurisdiction indicated on the
     signature page to this Warrant and the Holder has no present intention of
     becoming a resident of any other state or jurisdiction.

7.   CONDITIONS TO EXERCISE OF WARRANT.

         (a)  Each certificate evidencing the Warrant Shares issued upon
     exercise of this Warrant shall be stamped or imprinted with a legend
     substantially in the following form:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
         OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
         REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL IN FORM AND
         SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER,
         SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

         (b)  REMOVAL OF LEGED AND TRANSFER RESTRICTIONS. Any legend endorsed
     on a certificate pursuant to this Section 7 shall be removed, and the
     Company shall issue a certificate without such legend to the holder of such
     Warrant Shares if (i) such Warrant Shares are resold pursuant to a
     registration statement under the Securities Act and a prospectus meeting
     the requirements of Section 11 of the Securities Act is delivered or deemed
     delivered to the purchaser of such Warrant Shares, (ii) if such holder
     satisfies the requirements of Rule 144(k) under the Securities Act or (iii)
     if such holder provides the Company with an opinion of counsel for such
     holder of the Warrant Shares, reasonably satisfactory to the Company, to
     the effect that a sale, transfer or assignment of such Warrant Shares may
     be made without registration and that upon such sale, transfer or
     assignment such Warrant Shares will not be deemed "restricted securities,"
     as such term is defined in Rule 144 under the Securities Act.

                                       7

8. FRACTIONAL SHARES. No fractional Warrant Shares will be issued in connection
with any exercise of this Warrant, but in lieu of such fractional shares the
Company shall make a cash payment therefor upon the basis of the Exercise Price
then in effect.

9. NO RIGHTS OF STOCKHOLDERS. The Holder shall not be entitled to vote or
receive dividends or be deemed the holder of Warrant Shares or any other
securities of the Company which may at any time be issuable on the exercise of
this Warrant for any purpose, nor shall anything contained herein be construed
to confer upon the Holder 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 dividends or subscription rights or
otherwise with respect to the Warrant Shares until this Warrant shall have been
exercised and the Warrant Shares purchasable upon the exercise of this Warrant
shall have become deliverable, as provided in this Warrant.

10. Piggyback Registration. If the Company at any time proposes to register any
of its securities under the Securities Act for sale to the public, whether for
its own account or for the account of other security holders or both (except
with respect to registration statements on Forms S-4 or S-8 or another form not
available for registering the registrable securities for sale to the public), it
will give written notice to the Holder of its intention so to do. Upon the
written request of the Holder, received by the Company within 30 days after the
giving of any such notice by the Company, to register any of the Holder's
Warrant Shares, the Company will use reasonable best efforts to cause the
Holder's Warrant Shares as to which registration shall have been so requested to
be included in the securities to be covered by the registration statement
proposed to be filed by the Company. If any registration pursuant to this
Section 10 shall be, in whole or in part, an underwritten public offering of
Common Stock, the number of the Holder's Warrant Shares to be included in such
an underwriting may be reduced on a pari passu basis, or eliminated entirely, if
and to the extent that the managing underwriter shall be of the opinion that
such inclusion would adversely affect the marketing of the securities to be sold
by the Company.

11. TERM OF WARRANT. This Warrant shall become exercisable on the Warrant Date
and shall no longer be exercisable as of the earlier of (i) 5:00 p.m., New York
time, November 8, 2010; and (ii) immediately prior to the consummation of a
Change of Control.

12. MISCELLANEOUS.

         (a)  This Warrant shall be construed and enforced in accordance with
     and governed by the laws of the State of Nevada, without giving effect to
     principles of conflicts of laws.

         (b)  The headings in this Warrant are for purposes of reference only,
     and shall not limit or otherwise affect any of the terms of this Warrant.

         (c)  The terms of this Warrant shall be binding upon and shall inure to
     the benefit of any successors or assigns of the Company and of the Holder
     and of the Warrant Shares issued or issuable upon the exercise of this
     Warrant.

     agreement between the parties with regard to the subjects of this Warrant.

         (f) Upon receipt of evidence reasonably satisfactory to the Company of
     the loss, theft, destruction or mutilation of this 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

     Warrant, the Company at the Holder's expense will execute and deliver to
     the holder of record, in lieu thereof, a new Warrant of like date and
     tenor.
