                          COMMON STOCK PURCHASE WARRANT

                      To Purchase Shares of Common Stock of

                              BARNABUS ENERGY, INC.

                                                                FEBRUARY 8, 2006

FOR VALUE RECEIVED, Barnabus Energy, Inc., a Nevada corporation (the "Company"
or the "Corporation"), hereby grants to Coach Capital LLC (together with its
permitted successors and assigns, the "Registered Holder"), the right to
purchase at any time up to and including January 31, 2011 (the "Termination
Date"), the number of shares of fully paid and nonassessable Common Stock of the
Company, $0.001 par value per share (the "Common Stock", and those shares of
Common Stock purchasable under this Warrant being the "Warrant Shares"), equal
to (i) $1,500,000 divided by(ii) the Warrant Price (as defined below) then in
effect. This Warrant is being issued pursuant to that certain Investment
Agreement of even date herewith among the Company, the initial Registered Holder
and the other purchasers listed on the signature page thereof (the "Investment
Agreement). Capitalized terms used and not otherwise defined herein shall have
the meanings given to such terms in the Investment Agreement.

         1.       EXERCISE.

                  (a) This Warrant may be exercised by the Registered Holder on
or before the Termination Date, in whole or in part, by surrendering this
Warrant, with the purchase form appended hereto as Exhibit I duly executed by
the Registered Holder at the principal executive offices of the Company, or at
such other office or agency as the Company may designate, accompanied by payment
in full, in lawful money of the United States, of the Warrant Price payable in
respect of the number of Warrant Shares purchased upon such exercise. The
"Warrant Price" shall initially be $2.23 and from time to time shall be such
amount adjusted in accordance with Section 2 hereof.

                  (b) Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered to the Company as provided in subsection
1(a) above (the "Exercise Date"). At such time, the person or persons in whose
name or names any certificates for Warrant Shares shall be issuable upon such
exercise as provided in subsection 1(d) below shall be deemed to have become the
holder or holders of record of the Warrant Shares represented by such
certificates.

<PAGE>

                  (c) As soon as practicable after the exercise of this Warrant
in full or in part, and in any event within twenty (20) days thereafter, the
Company, at its expense, will cause to be issued in the name of, and delivered
to, the Registered Holder, or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may direct:

                           (i) a certificate or certificates for the number of
Warrant Shares to which the
Registered Holder shall be entitled upon such exercise; and

                           (ii) in case such exercise is in part only, a new
warrant or warrants (dated the
date hereof) of like tenor, calling in the aggregate on the face or faces
thereof for the number of Warrant Shares 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 purchased by the Registered Holder upon
such exercise.

         2.       ADJUSTMENTS.

                  (a) Adjustment for Stock Splits and Combinations. If the
Company shall at any time or from time to time after the date on which this
Warrant was first issued (the "Original Issue Date") effect a subdivision of the
outstanding Common Stock, the Warrant Price shall be proportionately decreased.
If the Company shall at any time or from time to time after the Original Issue
Date combine the outstanding shares of Common Stock, the Warrant Price shall be
proportionately increased. Any adjustment under this paragraph shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

                  (b) Adjustments for Other Dividends and Distributions. In the
event the Company at any time or from time to time after the Original Issue Date
shall make or issue, or fix a record date for the determination of holders of
Common Stock entitled to receive, a dividend or other distribution payable in
securities of the Company or in cash or other property, then and in each such
event the Registered Holder shall receive upon exercise hereof, in addition to
the Warrant Shares, the kind and amount of securities of the Company and/or cash
and other property which the Registered Holder would have been entitled to
receive had this Warrant been exercised on the date of such event.

                  (c) Adjustment for Mergers or Reorganizations, etc. If there
shall occur any reclassification, reorganization, recapitalization,
consolidation, sale of all or substantially all assets or merger involving the
Company in which the Common Stock is converted into or exchanged for securities,
cash or other property (other than a transaction covered by subsection 2(b)
above), then, following any such reclassification, reorganization,
recapitalization, consolidation, sale of all or substantially all assets or
merger, and without payment of any additional consideration thereof, the
Registered Holder shall receive upon exercise hereof the kind and amount of
securities, cash or other property which the Registered Holder would have been
entitled to receive if, immediately prior to such reclassification,
reorganization, recapitalization, consolidation or merger, sale of all or
substantially all assets, the Registered Holder had held the Warrant Shares,
giving application to all adjustments called for during such period under this
Section 2.

                                      -2-
<PAGE>

         The foregoing provisions of this Section 2(c) shall similarly apply to
successive reorganizations, consolidations, mergers, sales and transfers and to
the stock or securities of any other corporation that are at the time receivable
upon the exercise of this Warrant. If the per share consideration payable to the
holder hereof for Warrant Shares in connection with any such transaction is in a
form other than cash or marketable securities, then the value of such
consideration shall be determined in good faith by the Company's Board of
Directors. In all events, appropriate adjustment (as determined in good faith by
the Company's Board of Directors) shall be made in the application of the
provisions of this Warrant with respect to the rights and interests of the
Holder after the transaction, to the end that the provisions of this Warrant
shall be applicable after that event, as near as reasonably may be, in relation
to any shares or other property deliverable after that event upon exercise of
this Warrant.

                  (d) Subsequent Issuances. Except for Excluded Issuances, if
and whenever the Corporation shall issue or sell any shares of Common Stock for
a consideration per share less than the Warrant Price in effect immediately
prior to the time of such issue or sale, then and in each such case (a "TRIGGER
ISSUANCE") the then-existing Warrant Price shall be reduced, as of the close of
business on the effective date of the Trigger Issuance, to the lowest per share
price at which such Additional Shares of Common Stock were issued or sold.

                  If any time the Corporation shall in any manner grant
(directly and not by assumption in a merger or otherwise) any warrants or other
rights to subscribe for or to purchase, or any options for the purchase of,
Common Stock, or any stock or security convertible into or exchangeable for
Common Stock (such warrants, rights or options being called "OPTIONS" and such
convertible or exchangeable stock or securities being called "CONVERTIBLE
SECURITIES"), whether or not such Options or the right to convert or exchange
any such Convertible Securities are immediately exercisable, and the price per
share for which Common Stock is issuable upon the exercise of such Options or
upon the conversion or exchange of such Convertible Securities (determined by
dividing (A) the sum of (x) the total amount, if any, received or receivable by
the Corporation as consideration for the granting of such Options or Convertible
Securities, plus (y) the aggregate amount of additional consideration payable to
the Corporation upon the exercise of all such Options or the aggregate amount of
additional consideration, if any, payable upon the conversion or exchange of
such Convertible Securities, by (B) the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon the conversion or
exchange of all such Convertible Securities) shall be less than the Warrant
Price in effect immediately prior to the time of the granting of such Options or
Convertible Securities, then the Warrant Price shall be adjusted to equal the
price at which Common Stock is issuable upon such exercise or conversion or
exchange. No adjustment of the Warrant Price shall be made upon the actual issue
of such Common Stock upon exercise of such Options or upon the actual conversion
or exchange of such Convertible Securities.

                  If any shares of Common Stock, Options or Convertible
Securities shall be issued or sold for cash, the consideration received therefor
shall be deemed to be the amount received by the Corporation therefor plus the
amount, if any, to be received upon exercise or conversion thereof, without
deduction therefrom of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith. In case
any shares of Common Stock, Options or Convertible Securities shall be issued or
sold for a consideration other than cash or for a consideration including cash
and such other consideration, the amount of the consideration other than cash
received by the Corporation shall be deemed to be the fair value of such
consideration as determined in good faith by the Board, without deduction of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Corporation in connection therewith. In case any Options shall be issued
in connection with the issue and sale of other securities of the Corporation,
together comprising one integral transaction in which no specific consideration
is allocated to such Options by the parties thereto, such Options shall be
deemed to have been issued for such consideration as determined in good faith by
the Board. This determination of the fair value of consideration (or the
allocation thereof) need not be the amount recorded in the books and records of
the Corporation if the Board determines that the determination of different
amounts for different contexts is in the best interest of the Corporation and
its stockholders and creditors as a whole.

Corporation, (B) upon the conversion or exercise of Options or Convertible
Securities issued prior to the date hereof, unless such securities have been
amended or modified in any manner after the date hereof, (C) pursuant to the
Investment Agreement and other agreements in effect on the date hereof and
securities issued upon the exercise or conversion of those securities, (D) by
reason of a dividend, stock split or other distribution on shares of Common
Stock; (E) to David Saltman or Cheryl Bostater pursuant to the terms of their
employment agreements; (F) in connection with the acquisition of a business or
technology, the formation of a joint venture or a strategic investment; and (G)
at or above a price of $1.50 per share (which per share amount shall be adjusted
pro rata in the case of any split, dividend, combination or other event
affecting the number of outstanding shares of Common Stock).

                  (e) Milestone Adjustments. The Warrant Price shall be adjusted
as, when and to the extent provided in this paragraph (e); provided, however, no
further adjustments to the Warrant Price shall be made pursuant to this
paragraph (e) with respect to any fiscal quarter ended after November 30, 2006
if: (x) there was no Milestone Failure with respect to the fiscal quarter ended
November 30, 2006; and (y) the VWAP for any twenty (20) consecutive Trading Days
after the Milestone Announcement Date with respect to the fiscal quarter ended
November 30, 2006 is at least $4.00 per share (which per share amount shall be
adjusted pro rata in the case of any split, dividend, combination or other event
affecting the number of outstanding shares of Common Stock). Upon each Milestone
Failure Date, the Warrant Price in effect on such Milestone Failure Date shall,
at the election of the Registered Holder, be decreased to 115% of the VWAP for
the five (5) Trading Days immediately following such Milestone Failure Date.
With respect to each fiscal quarter ended after a Milestone Failure Date, if the
cumulative Net Sales through such fiscal quarter ended exceed the cumulative
Milestones such fiscal quarter, then all prior adjustments made pursuant to this
paragraph (e) shall be reversed. For purposes of this Warrant, the following
terms shall have the following meanings:

deliverable upon such reorganization, reclassification, consolidation, merger,

<PAGE>

1. CONVERSION.

      (a) By the Registered Holder. This Debenture may be converted by the
Registered Holder on or before the Maturity Date, in whole or in part, into that
number of shares of Common Stock equal to the principal amount of this Debenture
(or the portion being converted) divided by the Conversion Price then in effect
(the "Conversion Shares") by surrendering this Debenture, with the purchase form
appended hereto as Exhibit I duly executed by the Registered Holder at the
principal executive offices of the Company, or at such other office or agency as
the Company may designate.

      Each conversion of this Debenture pursuant to this paragraph (a) shall be
deemed to have been effected immediately prior to the close of business on the
day on which this Debenture shall have been surrendered to the Company as
provided above. At such time, the person or persons in whose name or names any
certificates for Conversion Shares shall be issuable upon such conversion as
provided below shall be deemed to have become the holder or holders of record of
the Conversion Shares represented by such certificates.

      As soon as practicable after the conversion of this Debenture in full or
in part, the Company, at its expense, will cause to be issued in the name of,
and delivered to, the Registered Holder, or as such Registered Holder (upon
payment by such Registered Holder of any applicable transfer taxes) may direct:

      (i) a certificate or certificates for the number of Conversion Shares to
which the Registered Holder shall be entitled upon such conversion; and

      (ii) in case such conversion is in part only, a new Debenture or
Debentures (dated the date hereof) of like tenor, in principal amount equal to
the principal amount hereof less the amount that has been converted into
Conversion Shares.

      (b) By the Company. This Debenture may be converted by the Company, in
whole but not in part, by giving notice thereof to the Registered Holder on any
Trading Day if (i) the VWAP for the twenty (20) consecutive Trading Days ended
on the Trading Day before the Trading Day on which notice of conversion is given
is at least $4.00 per share (which per share amount shall be adjusted pro rata
in the case of any split, dividend, combination or other event affecting the
number of outstanding shares of Common Stock), and (ii) a registration statement
covering the resale of the Conversion Shares was effective during such
20-Trading Day period and remains effective on the date of such notice. Upon the
Company's giving notice in accordance with the preceding sentence, this
Debenture shall without further action be converted into that number of
Conversion Shares equal to the outstanding principal amount hereof divided by
the Conversion Price then in effect. Each conversion of this Debenture pursuant
to this paragraph (b) shall be deemed to have occurred immediately prior to the
close of business on the day on which notice of conversion is given as provided
above. At such time, the person or persons in whose name or names any
certificates for Conversion Shares shall be issuable upon such conversion shall
be deemed to have become the holder or holders of record of the Conversion
Shares represented by such certificates.

<PAGE>

      As soon as practicable after the conversion of this Debenture the Company,
at its expense, will cause to be issued in the name of, and delivered to, the
Registered Holder, or as such Registered Holder (upon payment by such Registered
Holder of any applicable transfer taxes) may direct a certificate or
certificates for the number of Conversion Shares to which the Registered Holder
shall be entitled upon such conversion.

      (c) Conversion Price. As used herein, the Conversion Price shall initially
be $1.46 and from time to time shall be such amount as adjusted as provided
herein.

      2. ADJUSTMENTS.

      (a) Adjustment for Stock Splits and Combinations. If the Company shall at
any time or from time to time after the date on which this Debenture was first
issued (the "Original Issue Date") effect a subdivision of the outstanding
Common Stock, the Conversion Price shall be proportionately decreased. If the
Company shall at any time or from time to time after the Original Issue Date
combine the outstanding shares of Common Stock, the Conversion Price shall be
proportionately increased. Any adjustment under this paragraph shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

      (b) Adjustments for Other Dividends and Distributions. In the event the
Company at any time or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution payable in
securities of the Company or in cash or other property, then and in each such
event the Registered Holder shall receive upon conversion hereof, in addition to
the Conversion Shares issuable hereunder, the kind and amount of securities of
the Company and/or cash and other property which the Registered Holder would
have been entitled to receive had this Debenture been converted on the date of
such event.

      (c) Adjustment for Mergers or Reorganizations, etc. If there shall occur
any reclassification, reorganization, recapitalization, consolidation, sale of
all or substantially all assets or merger involving the Company in which the
Common Stock is converted into or exchanged for securities, cash or other
property (other than a transaction covered by subsection 2(b) above), then,
following any such reclassification, reorganization, recapitalization,
consolidation, sale of all or substantially all assets or merger, and without
payment of any additional consideration thereof, the Registered Holder shall
receive upon conversion hereof the kind and amount of securities, cash or other
property which the Registered Holder would have been entitled to receive if,
immediately prior to such reclassification, reorganization, recapitalization,
consolidation or merger, sale of all or substantially all assets, this Debenture
had been converted.

      The foregoing provisions of this Section 2(c) shall similarly apply to
successive reorganizations, consolidations, mergers, sales and transfers and to
the stock or securities of any other corporation that are at the time receivable
upon the conversion of this Debenture. If the per share consideration payable to
the holder hereof for Conversion Shares in connection with any such transaction
is in a form other than cash or marketable securities, then the value of such
consideration shall be determined in good faith by the Company's Board of
Directors. In all events, appropriate adjustment (as determined in good faith by
the Company's Board of Directors) shall be made in the application of the
provisions of this Debenture with respect to the rights and interests of the
Holder after the transaction, to the end that the provisions of this Debenture
shall be applicable after that event, as near as reasonably may be, in relation
to any shares or other property deliverable after that event upon conversion of
this Debenture.

                                       3

      (d) Subsequent Issuances. Except for Excluded Issuances, if and whenever
the Corporation shall issue or sell any shares of Common Stock for a
consideration per share less than the Conversion Price in effect immediately
prior to the time of such issue or sale, then and in each such case (a "Trigger
Issuance") the then-existing Conversion Price shall be reduced, as of the close
of business on the effective date of the Trigger Issuance, to the lowest per
share price at which such Additional Shares of Common Stock were issued or sold.

      In case at any time the Corporation shall in any manner grant (directly
and not by assumption in a merger or otherwise) any Warrants or other rights to
subscribe for or to purchase, or any options for the purchase of, Common Stock
or any stock or security convertible into or exchangeable for Common Stock (such
Warrants, rights or options being called "Options" and such convertible or
exchangeable stock or securities being called "Convertible Securities"), whether
or not such Options or the right to convert or exchange any such Convertible
Securities are immediately exercisable, and the price per share for which Common
Stock is issuable upon the exercise of such Options or upon the conversion or
exchange of such Convertible Securities (determined by dividing (A) the sum of
(x) the total amount, if any, received or receivable by the Company as
consideration for the granting of such Options or Convertible Securities, plus
(y) the aggregate amount of additional consideration payable to the Company upon
the conversion of all such Options or the aggregate amount of additional
consideration, if any, payable upon the conversion or exchange of such
Convertible Securities, by (B) the total maximum number of shares of Common
Stock issuable upon the exercise of such Options or upon the conversion or
exchange of all such Convertible Securities) shall be less than the Conversion
Price in effect immediately prior to the time of the granting of such Options or
Convertible Securities, then the Conversion Price shall be adjusted to equal the
price at which Common Stock is issuable upon such conversion or conversion or
exercise. No adjustment of the Conversion Price shall be made upon the actual
issue of such Common Stock upon exercise of such Options or upon the actual
conversion or exchange of such Convertible Securities.

      In case any shares of Common Stock, Options or Convertible Securities
shall be issued or sold for cash, the consideration received therefor shall be
deemed to be the amount received by the Company therefor, without deduction
therefrom of any expenses incurred or any underwriting commissions or
concessions paid or allowed by the Corporation in connection therewith. In case
any shares of Common Stock, Options or Convertible Securities shall be issued or
sold for a consideration other than cash or for a consideration including cash
and such other consideration, the amount of the consideration other than cash
received by the Corporation shall be deemed to be the fair value of such
consideration as determined in good faith by the Board, without deduction of any
expenses incurred or any underwriting commissions or concessions paid or allowed
by the Company in connection therewith. In case any Options shall be issued in
connection with the issue and sale of other securities of the Company, together
comprising one integral transaction in which no specific consideration is
allocated to such Options by the parties thereto, such Options shall be deemed
to have been issued for such consideration as determined in good faith by the
Board. This determination of the fair value of consideration (or the allocation
thereof) need not be the amount recorded in the books and records of the Company
if the Board determines that the determination of different amounts for
different contexts is in the best interest of the Company and its stockholders
and creditors as a whole.

      As used herein, "Excluded Issuances" shall mean any issuance of Common
Stock (A) to directors, officers, employees or consultants of the Company, (B)
upon the conversion or conversion of Options or Convertible Securities issued
prior to the date hereof, unless such securities have been amended or modified
in any manner after the date hereof, (C) pursuant to the Investment Agreement
and other agreements in effect on the date hereof and securities issued upon the
conversion or conversion of those securities, (D) by reason of a dividend, stock
split or other distribution on shares of Common Stock; (E) to David Saltman or
Cheryl Bostater pursuant to the terms of their employment agreements; and (F) in
connection with the acquisition of a business or technology, the formation of a
joint venture or a strategic investment.

      (e) Milestone Adjustments. The Conversion Price shall be adjusted as, when
and to the extent provided in this paragraph (e); provided, however, no further
adjustments to the Conversion Price shall be made pursuant to this paragraph (e)
with respect to any fiscal quarter ended after November 30, 2006 if: (x) there
was no Milestone Failure with respect to the fiscal quarter ended November 30,
2006; and (y) the VWAP for any twenty (20) consecutive Trading Days after the
Milestone Announcement Date with respect to the fiscal quarter ended November
30, 2006 is at least $4.00 per share (which per share amount shall be adjusted
pro rata in the case of any split, dividend, combination or other event
affecting the number of outstanding shares of Common Stock). Upon each Milestone
Failure Date, the Conversion Price in effect on such Milestone Failure Date
shall, at the election of the Registered Holder, be decreased to the VWAP for
the five (5) Trading Days immediately following such Milestone Failure Date
multiplied by the Designated Discount Rate applicable to such Milestone Failure
as set forth in the Milestone table below. With respect to each fiscal quarter
ended after a Milestone Failure Date, if the cumulative Net Sales through such
fiscal quarter ended exceed the cumulative Milestones through such fiscal
quarter, then all prior adjustments to this paragraph (e) shall be reversed. For
purposes of this Debenture, the following terms shall have the following
meanings:

of the fourth fiscal quarter of a given fiscal year, the annual report on Form
10-K, 10-KSB or such other form the Company is then eligible to use, in each
case, filed by the Company with the SEC pursuant to Section 13 or 15(d) of the

            (f) Certificate as to Adjustments. Upon the occurrence of each
      adjustment or readjustment pursuant to this Section 2, the Company at its

      Debenture shall be exercisable, the Conversion Price and the method of
      calculation of each) and showing in detail the facts upon which such
      adjustment or readjustment is based.

            (g) Adjustment to Conversion Shares. Whenever the Conversion Price
      is adjusted pursuant to this Section 2, there shall be a corresponding
      adjustment made to the number of Conversion Shares upon conversion hereof.

      3. FRACTIONAL SHARES. The Company shall not be required upon the
conversion of this Debenture to issue any fractional shares, and shall round any
fractional shares to the next highest whole number of shares. If a fractional
share interest arises upon any conversion or conversion of the Debenture, the
Company shall eliminate such fractional share interest by paying the Registered
Holder an amount computed by multiplying the fractional interest by the Fair
Market Value of a full share of common Stock.

            The "Fair Market Value" per share of Common Stock shall be
determined as

      (i) if the Common Stock is listed on a national securities exchange, the
NASDAQ Small Cap Market, the NASDAQ National Market, the OTCBB or another
nationally recognized trading system as of the Conversion Date, the Fair Market
Value per share of Common Stock shall be deemed to be the average of the high
and low reported sale prices per share of Common Stock thereon on the trading
day immediately preceding the Conversion Date (provided that if no such price is
reported on such day, the Fair Market Value per share of Common Stock shall be
determined pursuant to clause (ii)).

      (ii) In all other cases, the Fair Market Value per share of Common Stock
shall be deemed to be the amount most recently determined by the Board of
Directors to represent the fair market value per share of the Common Stock.
Notwithstanding the foregoing, if the Board of Directors has not made such a
determination within the three-month period prior to the Conversion Date, then
(A) the Board of Directors shall make a determination of the Fair Market Value
per share of the Common Stock within 20 days of a request by the Registered
Holder that it do so, and (B) the conversion of this Debenture pursuant to this
subsection 1(b) shall be delayed until such determination is made.

Agreement are true and correct as if made by the Registered Holder on the date
of conversion.

      5. REQUIREMENTS FOR TRANSFER.

            (a) This Debenture and the Conversion Shares shall not be sold or
transferred unless either (i) they first shall have been registered under the

      TO RULE 144 OF SUCH ACT.

The foregoing legend shall be removed from the certificates representing any
Conversion Shares, at the request of the holder thereof, at such time as (i)
they become eligible for resale pursuant to an effective registration statement
or Rule 144(k) under the Act or (ii) the Company shall have received either an
opinion of counsel or a "no-action" letter from the SEC to the effect that any
transfer of the Conversion Shares represented by such certificates will not
violate the Act and applicable state securities laws.

      6. EVENT OF DEFAULT. The occurrence of any of following events shall
constitute an "Event of Default" hereunder:

            (a) the failure of the Corporation to make any payment of principal
on this Debenture when due, whether at maturity, upon acceleration or otherwise;

insolvency, readjustment of debt, dissolution or liquidation law of any
jurisdiction; or any such petition or application is filed, or any such
proceeding is commenced, against the Corporation and either (i) the Corporation
by any act indicates its approval thereof, consents thereto or acquiescence
