nonassessable  shares  of Common Stock at a per share purchase price of $10.00.
The aforedescribed purchase  price  per share, as adjusted from time to time as
herein provided, is referred to herein as the "Purchase Price."  The number and
character of such shares of Common Stock  and the Purchase Price are subject to
adjustment as provided herein.  The Company  may  reduce  the Purchase Price of
some  or  all  of the Warrant Shares, permanently or temporarily,  without  the
consent of the Holder provided ten days prior notice of such reduction is given
to the Holder.   Capitalized  terms used and not otherwise defined herein shall
have  the  meanings  set forth in  that  certain  Subscription  Agreement  (the
"SUBSCRIPTION AGREEMENT"), dated January ___, 2007, entered into by the Company
and initial Holder of this Warrant.

      As  used  herein  the  following  terms,  unless  the  context  otherwise
requires, have the following respective meanings:

      (a)   The term "Company"  shall  mean  South  Texas  Oil  Company and any
corporation  which shall succeed or assume the obligations of South  Texas  Oil
Company hereunder.

      (b)   The  term  "Common  Stock" includes (a) the Company's common stock,
$.001  par value per share, as authorized  on  the  date  of  the  Subscription
Agreement,  and  (b)  any  Other  Securities into which or for which any of the
securities described in (a) may be converted or exchanged pursuant to a plan of
recapitalization, reorganization, merger, sale of assets or otherwise.

      (c)   The term "Other Securities"  refers to any stock (other than Common
Stock) and other securities of the Company  or  any  other person (corporate or
otherwise) which the holder of the Warrant at any time  shall  be  entitled  to
receive,  or shall have received, on the exercise of the Warrant, in lieu of or
in addition  to  Common  Stock, or which at any time shall be issuable or shall
have been issued in exchange  for  or  in  replacement of Common Stock or Other
Securities pursuant to Section 5 or otherwise.

      (d)   The term "Warrant Shares" shall mean the Common Stock issuable upon

      1.    Exercise of Warrant.

            1.1.  Number of Shares Issuable  upon Exercise.  From and after the
Issue Date through and including the Expiration  Date,  the Holder hereof shall
be entitled to receive, upon exercise of this Warrant in  whole  in  accordance
with  the  terms of subsection 1.2 or upon exercise of this Warrant in part  in
accordance with  subsection 1.3,  Common  Stock  of  the  Company,  subject  to
adjustment pursuant to Section 4.

            1.2.  Full  Exercise.  This Warrant may be exercised in full by the
Holder hereof by delivery  of  an  original  or  facsimile  copy of the form of
subscription  attached  as  Exhibit A  hereto  (the "Subscription  Form")  duly
executed by such Holder and surrender of the original  Warrant within three (3)
days of exercise, to the Company at its principal office  or  at  the office of
its Warrant Agent (as provided hereinafter), accompanied by payment,  in  cash,
wire  transfer  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 for which this Warrant is then exercisable by the  Purchase  Price
then in effect.

            1.3.  Partial Exercise.  This Warrant may be exercised in part (but
not  for a fractional share) by surrender of this Warrant in the manner and  at
the place  provided  in  subsection 1.2  except  that the amount payable by the
Holder  on such partial exercise shall be the amount  obtained  by  multiplying
(a) the number  of whole shares of Common Stock designated by the Holder in the
Subscription Form  by  (b) the  Purchase  Price  then  in  effect.  On 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 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, the whole number of shares of Common
Stock for which such Warrant may still be exercised for the balance of.

            1.4.  Fair Market Value.  Fair  Market  Value  of a share of Common
Stock as of a particular date (the "Determination Date") shall mean:

                  (a)   If the Company's Common Stock is traded  on an exchange
or is quoted on the National Association of Securities Dealers, Inc.  Automated
Quotation ("NASDAQ"), National Market System, the NASDAQ Capital Market  or the
American   Stock   Exchange,   LLC,  then  the  closing  or  last  sale  price,
respectively, reported for the last  business  day  immediately  preceding  the
Determination Date;

                  (b)   If  the  Company's  Common  Stock  is  not traded on an
exchange or on the NASDAQ National Market System, the NASDAQ Capital  Market or
the  American  Stock  Exchange,  Inc.,  but  is  traded in the over-the-counter
market, then the average of the closing bid and ask  prices  reported  for  the
last business day immediately preceding the Determination Date;

                  (c)   Except   as   provided  in  clause  (d) below,  if  the
Company's Common Stock is not publicly  traded,  then  as  the  Holder  and the
Company  agree,  or  in  the  absence  of  such an agreement, by arbitration in
accordance   with  the  rules  then  standing  of  the   American   Arbitration
Association, before  a  single  arbitrator to be chosen from a panel of persons
qualified by education and training to pass on the matter to be decided; or

                  (d)   If the Determination Date is the date of a liquidation,
dissolution or winding up, or any event deemed to be a liquidation, dissolution
or winding up pursuant to the Company's charter, then all amounts to be payable
per share to holders of the Common  Stock  pursuant to the charter in the event
of such liquidation, dissolution or winding  up,  plus  all other amounts to be
payable  per  share  in  respect of the Common Stock in liquidation  under  the
charter, assuming for the purposes of this clause (d) that all of the shares of
Common Stock then issuable upon exercise of all of the Warrants are outstanding
at the Determination Date.

            1.5.  Company  Acknowledgment. The Company will, at the time of the
exercise of the Warrant, upon  the  request of the Holder hereof acknowledge in
writing its continuing obligation to  afford to such Holder any rights to which
such Holder shall continue to be entitled  after  such  exercise  in accordance
with the provisions of this Warrant. If the Holder shall fail to make  any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such Holder any such rights.

            1.6.  Trustee  for  Warrant  Holders. In the event that a qualified
bank or trust company shall have been appointed  as  trustee  for the Holder of
the Warrants pursuant to Subsection 3.2, such bank or trust company  shall have
all  the  powers  and duties of a warrant agent (as hereinafter described)  and
shall accept, in its  own name for the account of the Company or such successor
person as may be entitled thereto, all amounts otherwise payable to the Company
or such successor, as the  case may be, on exercise of this Warrant pursuant to
this Section 1.

            1.7.  Delivery of Stock Certificates, etc. on Exercise. The Company
agrees that the shares of Common  Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the  Holder  hereof as the record owner of such
shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for such shares  as  aforesaid.  As  soon  as
practicable  after  the exercise of this Warrant in full or in part, and in any
event  within three (3)  business  days  thereafter  ("Warrant  Share  Delivery
Date"),  the  Company  at  its  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  in compliance with applicable securities
laws, a certificate or certificates for  the number of duly and validly issued,
fully paid and nonassessable shares of Common  Stock  (or  Other Securities) to
which  such Holder shall be entitled on 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 Fair Market Value of one full share of
Common Stock, together with any  other  stock  or other securities and property
(including cash, where applicable) to which such  Holder  is entitled upon such
exercise  pursuant to Section 1 or otherwise.  The Company understands  that  a
delay in the  delivery  of  the Warrant Shares after the Warrant Share Delivery
Date could result in economic  loss  to  the  Holder.   As  compensation to the
Holder for such loss, the Company agrees to pay (as liquidated  damages and not
as  a penalty) to the Holder for late issuance of Warrant Shares upon  exercise
of this  Warrant  the  amount  of $100 per business day after the Warrant Share
Delivery Date for each $10,000 of  Purchase  Price  of Warrant Shares for which
this Warrant is exercised which are not timely delivered.   The  Company  shall
pay  any  payments  incurred  under this Section in immediately available funds
upon demand.  Furthermore, in addition  to  any  other  remedies  which  may be
available to the Holder, in the event that the Company fails for any reason  to
effect  delivery  of the Warrant Shares by the Warrant Share Delivery Date, the
Holder may revoke all or part of the relevant Warrant exercise by delivery of a
notice to such effect to the Company whereupon the Company and the Holder shall
each  be restored to  their  respective  positions  immediately  prior  to  the
exercise  of  the  relevant portion of this Warrant, except that the liquidated
damages described above  shall be payable through the date notice of revocation
or rescission is given to  the  Company.   The  maximum  amount  of  liquidated
damages  payable  hereunder  pursuant to this Section and Section 10 hereof  is
fifteen percent (15%) of the aggregate exercise price.

            1.8   Buy-In.  In  addition  to  any  other rights available to the
Holder,  if  the Company fails to deliver to a Holder  the  Warrant  Shares  as
required pursuant  to  this  Warrant,  within seven (7) business days after the
Warrant Share Delivery Date and the Holder  or a broker on the Holder's behalf,
purchases (in an open market transaction or otherwise)  shares  of common stock
to deliver in satisfaction of a sale by such Holder of the Warrant Shares which
the  Holder  was  entitled to receive from the Company (a "BUY-IN"),  then  the
Company shall pay in  cash to the Holder (in addition to any remedies available
to or elected by the Holder)  the  amount  by  which  (A)  the  Holder's  total
purchase  price  (including  brokerage  commissions,  if any) for the shares of
common  stock  so  purchased exceeds (B) the aggregate Purchase  Price  of  the
Warrant Shares required  to  have been delivered together with interest thereon
at a rate of 15% per annum, accruing until such amount and any accrued interest
thereon is paid in full (which  amount  shall be paid as liquidated damages and
not as a penalty).  For example, if a Holder  purchases  shares of Common Stock
having  a  total purchase price of $11,000 to cover a Buy-In  with  respect  to
$10,000 of Purchase Price of Warrant Shares to have been received upon exercise
of this Warrant,  the  Company shall be required to pay the Holder $1,000, plus
interest. The Holder shall  provide  the  Company written notice indicating the
amounts payable to the Holder in respect of the Buy-In.

      2.    Cashless Exercise.

            (a)   Except  as  described  below,  if  a  registration  statement
registering the Warrant Shares with the Securities and Exchange Commission on a
Form  S-1,  SB-2  or  S-3,  for  unrestricted  public   resale   ("Registration
Statement")  is  effective  and the Holder may sell its shares of Common  Stock
upon exercise hereof pursuant  to  the Registration Statement, this Warrant may
be exercisable in whole or in part for  cash  only  as  set  forth in Section 1
above.  If such Registration Statement is not available, payment  upon exercise
may  be  made at the option of the Holder either in cash, wire transfer  or  by
certified  or  official bank check payable to the order of the Company equal to
the  applicable aggregate  Purchase  Price  or  (i)  by  cashless  exercise  in
accordance  with  Section (b) below,  or  (ii) by  a  combination of any of the
foregoing methods, for the number of shares of Common Stock  specified  in such
form  (as  such exercise number shall be adjusted to reflect any adjustment  in
the total number of shares of Common Stock issuable to the Holder per the terms
of this Warrant)  and  the  Holder  shall  thereupon be entitled to receive the
number of duly authorized, validly issued, fully-paid and non-assessable shares
of Common Stock (or Other Securities) determined as provided herein.

            (b)   If the Fair Market Value of  one  share  of  Common  Stock is
greater  than  the  Purchase  Price  (at  the  date of calculation as set forth
below), in lieu of exercising this Warrant for cash,  the  Holder  may elect to
receive shares equal to the value (as determined below) of this Warrant (or the
portion thereof being cancelled) by surrender of this Warrant at the  principal
office of the Company together with the properly endorsed Subscription  Form 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-B)
                            A

            Where X=    the  number  of  shares of Common Stock to be issued to
the holder

                  Y=    the number of shares  of Common Stock purchasable under
                        the Warrant or, if only  a  portion  of  the Warrant is
                        being  exercised,  the  portion  of  the Warrant  being
                        exercised (at the date of such calculation)

                  A=    the  average of the closing bid prices  of  the  Common
                        Stock  for  the five (5) Trading Days immediately prior
                        to (but not including) the Exercise Date

                  B=    Purchase  Price  (as  adjusted  to  the  date  of  such
                        calculation)

            For purposes of Rule 144  promulgated  under  the  1933  Act, it is
intended,  understood  and  acknowledged  that  the Warrant Shares issued in  a
cashless exercise transaction shall be deemed to  have  been  acquired  by  the
Holder,  and  the holding period for the Warrant Shares shall be deemed to have
commenced, on the date this Warrant was originally issued.

      3.    Adjustment for Reorganization, Consolidation, Merger, etc.

            3.1.  Reorganization,  Consolidation,  Merger, etc.  In case at any
time  or  from  time  to time, the Company shall (a) effect  a  reorganization,
(b) consolidate with or  merge  into  any  other  person or (c) transfer all or
substantially all of its properties or assets to any  other  person  under  any
plan or arrangement contemplating the dissolution of the Company, then, in each
such case, as a condition to the consummation of such a transaction, proper and
adequate  provision  shall  be  made  by the Company whereby the Holder of this
Warrant, on the exercise hereof as provided in Section 1, at any time after the
consummation of such reorganization, consolidation  or  merger or the effective
date of such dissolution, as the case may be, shall receive,  in  lieu  of  the
Common  Stock  (or  Other  Securities)  issuable on such exercise prior to such
consummation  or  such  effective date, the  stock  and  other  securities  and
property (including cash)  to  which  such Holder would have been entitled upon
such consummation or in connection with  such  dissolution, as the case may be,
if such Holder had so exercised this Warrant, immediately  prior  thereto,  all
subject to further adjustment thereafter as provided in Section 4.

            3.2.  Dissolution.   In the event of any dissolution of the Company
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution,  shall  at its expense deliver or cause
to be delivered the stock and other securities and  property  (including  cash,
where  applicable) receivable in accordance with Section 3.1 by the Holder upon
their exercise  after  the  effective date of such dissolution pursuant to this
Section 3 to a bank or trust  company (a "Trustee") having its principal office
in New York, NY, as trustee for the Holder.

            3.3.  Continuation    of    Terms.     Upon   any   reorganization,
consolidation, merger or transfer (and any dissolution  following any transfer)
referred to in this Section 3, this Warrant shall continue  in  full  force and
effect  and  the  terms hereof shall be applicable to the Other Securities  and
property receivable  on  the exercise of this Warrant after the consummation of
such  reorganization,  consolidation   or  merger  or  the  effective  date  of
dissolution following any such transfer,  as  the  case  may  be,  and shall be
binding upon the issuer of any Other Securities, including, in the case  of any
such  transfer, the person acquiring all or substantially all of the properties
or assets  of  the  Company,  whether  or  not such person shall have expressly
assumed the terms of this Warrant as provided  in Section 4.  In the event this
Warrant does not continue in full force and effect  after  the  consummation of
the transaction described in this Section 3, then only in such event  will  the
Company's securities and property (including cash, where applicable) receivable
by  the  Holder  of the Warrants be delivered to the Trustee as contemplated by
Section 3.2.

            3.4   Share  Issuance.   Until  the Expiration Date, if the Company
shall issue any Common Stock except for the Excepted  Issuances  (as defined in
the Subscription Agreement), prior to the complete exercise of this Warrant for
a  consideration  less than the Purchase Price that would be in effect  at  the
time of such issue, then, and thereafter successively upon each such issue, the
Purchase Price shall  be  reduced  to  such  other  lower  purchase price.  For
purposes of this adjustment, the issuance of any security or debt instrument of
the Company carrying the right to convert such security or debt instrument into
Common Stock or of any warrant, right or option to purchase  Common Stock shall
result in an adjustment to the Purchase Price upon the issuance  of  the above-
described security, debt instrument, warrant, right, or option if such issuance
is at a price lower than the Purchase Price in effect upon such issuance.   The
reduction of the Purchase Price described in this Section 3.4 is subject to the
provisions  of, and in addition to the other rights of the Holder described in,
the Subscription Agreement.

      4.    Extraordinary Events Regarding Common Stock.  In the event that the
Company shall  (a) issue additional shares of the Common Stock as a dividend or
other distribution  on  outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or  (c) combine  its  outstanding  shares of the Common
Stock into a smaller number of shares of the Common Stock, then,  in  each such
event,  the  Purchase  Price  shall,  simultaneously with the happening of such
event, be adjusted by multiplying the then  Purchase  Price  by a fraction, the
numerator  of  which shall be the number of shares of Common Stock  outstanding
immediately prior  to  such  event  and  the  denominator of which shall be the
number of shares of Common Stock outstanding immediately  after such event, and
the product so obtained shall thereafter be the Purchase Price  then in effect.
The Purchase Price, as so adjusted, shall be readjusted in the same manner upon
the  happening  of  any  successive  event or events described herein  in  this
Section 4. The number of shares of Common Stock that the Holder of this Warrant
shall thereafter, on the exercise hereof  as provided in Section 1, be entitled
to receive shall be adjusted to a number determined  by  multiplying the number
of shares of Common Stock that would otherwise (but for the  provisions of this
Section 4)  be  issuable  on  such  exercise  by  a  fraction of which  (a) the
numerator is the Purchase Price that would otherwise (but for the provisions of
this Section 4) be in effect, and (b) the denominator  is the Purchase Price in
effect on the date of such exercise.

      5.    Certificate as to Adjustments.  In each case  of  any adjustment or
readjustment  in  the  shares of Common Stock issuable on the exercise  of  the
Warrants, the Company at  its  expense  will promptly cause its Chief Financial
Officer  or  other  appropriate  designee  to   compute   such   adjustment  or
readjustment  in  accordance  with  the  terms  of  the  Warrant and prepare  a
certificate setting forth such adjustment or readjustment and showing in detail
the  facts  upon  which such adjustment or readjustment is based,  including  a
statement of (a) the  consideration  received  or receivable by the Company for
any additional shares of Common Stock issued or  sold  or  deemed  to have been
issued or sold, (b) the number of shares of Common Stock outstanding  or deemed
to  be  outstanding,  and  (c) the  Purchase Price and the number of shares  of
Common  Stock  to  be  received  upon  exercise  of  this  Warrant,  in  effect
immediately  prior  to  such adjustment or  readjustment  and  as  adjusted  or
readjusted as provided in  this Warrant. The Company will forthwith mail a copy
of each such certificate to  the Holder of the Warrant and any Warrant Agent of
the Company (appointed pursuant to Section 11 hereof).

      6.    Reservation  of  Stock,  etc.  Issuable  on  Exercise  of  Warrant;
Financial  Statements.    The Company  will  at  all  times  reserve  and  keep
available, solely for issuance  and  delivery  on the exercise of the Warrants,
all shares of Common Stock from time to time issuable  on  the  exercise of the
Warrant.   This  Warrant  entitles the Holder hereof to receive copies  of  all
financial and other information  distributed  or  required to be distributed to
the holders of the Company's Common Stock.

      7.    Assignment;  Exchange  of  Warrant.   Subject  to  compliance  with
applicable securities laws, this Warrant, and the rights  evidenced hereby, may
be  transferred  by  any  registered  holder  hereof (a "Transferor").  On  the
surrender for exchange of this Warrant, with the  Transferor's  endorsement  in
the  form  of Exhibit B attached hereto (the "Transferor Endorsement Form") and
together with an opinion of counsel reasonably satisfactory to the Company that
the transfer  of  this Warrant will be in compliance with applicable securities
laws, the Company at  its  expense,  twice,  only,  but  with  payment  by  the
Transferor  of  any  applicable transfer taxes, will issue and deliver to or on
the order of the Transferor thereof a new Warrant or Warrants of like tenor, in
the  name  of  the  Transferor  and/or  the  transferee(s)  specified  in  such
Transferor Endorsement  Form (each a "Transferee"), 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  so surrendered by the Transferor.  No such
transfers shall result in a public distribution of the Warrant.

      8.    Replacement  of  Warrant.   On   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 of this
Warrant,  on  delivery  of   an  indemnity  agreement  or  security  reasonably
satisfactory in form and amount  to  the  Company  or,  in the case of any such
mutilation, on surrender and cancellation of this Warrant,  the  Company at its
expense, twice only, will execute and deliver, in lieu thereof, a  new  Warrant
of like tenor.

      9.    Maximum  Exercise.    The  Holder shall not be entitled to exercise
this Warrant on an exercise date, in connection  with  that number of shares of
Common Stock which would be in excess of the sum of (i) the number of shares of
Common Stock beneficially owned by the Holder and its affiliates on an exercise
date, and (ii) the number of shares of Common Stock issuable  upon the exercise
of this Warrant with respect to which the determination of this  limitation  is
being  made  on an exercise date, which would result in beneficial ownership by
the Holder and  its  affiliates of more than 4.99% of the outstanding shares of
Common Stock on such date.   For  the  purposes  of  the  immediately preceding
sentence,   beneficial  ownership  shall  be  determined  in  accordance   with
Section 13(d) of   the  Securities  Exchange  Act  of  1934,  as  amended,  and
Regulation 13d-3 thereunder.  Subject to the foregoing, the Holder shall not be
limited to aggregate  exercises which would result in the issuance of more than
4.99%.  The Holder may increase the permitted beneficial ownership amount up to
9.99% upon and effective after sixty-one (61) days prior notice to the Company.
The Holder may allocate  which of the equity of the Company deemed beneficially
owned by the Holder shall  be  included in the 4.99% amount described above and
which shall be allocated to the excess above 4.99%.

      10.   Registration Rights.   The  Company  and  initial  Holder  of  this
Warrant entered into a subscription agreement dated as of July 27, 2005 ("Prior
Subscription Agreement").  The Holder is hereby granted the registration rights
vis-{a`}-vis  the Warrant Shares as set forth in Section 11.1(ii) of such Prior
Subscription Agreement.  The relevant terms of the Prior Subscription Agreement
are incorporated herein by this reference.

      11.   Warrant Agent.  The Company may, by written notice to the Holder of
the Warrant, appoint  an  agent  (a "Warrant Agent") for the purpose of issuing
Common Stock on the exercise of this  Warrant pursuant to Section 1, exchanging
this Warrant pursuant to Section 7, and  replacing  this  Warrant  pursuant  to
Section 8,  or any of the foregoing, and thereafter any such issuance, exchange
or replacement,  as  the  case  may  be,  shall  be made at such office by such
Warrant Agent.

      12.   Transfer on the Company's Books.  Until this Warrant is transferred
on the books of the Company, the Company may treat the registered holder hereof
as the absolute owner hereof for all purposes, notwithstanding  any  notice  to
the contrary.

      13.   Notices.   All notices, demands, requests, consents, approvals, and
other  communications  required or permitted hereunder shall be in writing and,
unless  otherwise specified  herein,  shall  be  (i)  personally  served,  (ii)
deposited  in  the  mail,  registered  or  certified, return receipt requested,
postage prepaid, (iii) delivered by reputable  air courier service with charges
prepaid,  or  (iv)  transmitted  by  hand  delivery,  telegram,  or  facsimile,
addressed as set forth below or to such other address as  such party shall have
