WARRANT TO PURCHASE

COMMON STOCK OF

ROCK ENERGY RESOURCES, INC.

This certifies that, for value received, ROCK ENERGY RESOURCES, INC., a Delaware corporation (the “Company”), grants PERM ENERGY ADVISORS, INC., a Delaware corporation, or its registered assigns (the “Registered Holder”), the right to subscribe for and purchase from the Company, at the Exercise Price (as defined herein), from and after 9:00 a.m. Texas time on September 30, 2008 (the “Exercise Date”) and to and including 5:00 p.m., Texas time on the fifth anniversary of the Exercise Date (the “Expiration Date”), Four Million Seven Hundred Sixty-One Thousand Nine Hundred Five (4,761,905) shares, as such number of shares may be adjusted from time to time as described herein (the “Warrant Shares”), of the Company’s common stock, par value $.0001 per share (the “Common Stock”), subject to the provisions and upon the terms and conditions herein set forth.  The “Exercise Price” per share of Common Stock shall be $1.68 per share.

This Warrant is issued in connection with the transactions described in that certain Stock Purchase Agreement between the Company and PERM Energy Advisors, Inc. dated as of March 31, 2007 (the “Purchase Agreement”).  The holder of this Warrant is subject to certain restrictions set forth in the Purchase Agreement and shall be entitled to certain rights and privileges set forth in the Purchase Agreement.

Section 1.                                            Registration.  The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Records”), in the name of the Registered Holder.  The Company may deem and treat the Registered Holder as the absolute owner of this Warrant for the purpose of any exercise hereof or any distribution to the Registered Holder.

Section 2.                                            Registration of Transfers and Exchanges.

(a)                                  Subject to Section 9 hereof, the Company shall register the transfer of this Warrant, in whole or in part, upon records to be maintained by the Company for that purpose, upon surrender of this Warrant, with the Form of Assignment attached hereto completed and duly endorsed

by the Registered Holder, to the Company at the office specified in or pursuant to Section 3(b).  Upon any such registration of transfer, a new Warrant, in substantially the form of this Warrant, evidencing the Common Stock purchase rights so transferred shall be issued to the transferee and a new Warrant, in similar form, evidencing the remaining Common Stock purchase rights not so transferred, if any, shall be issued to the Registered Holder.

(b)                                 This Warrant is exchangeable, upon the surrender hereof by the Registered Holder at the office of the Company specified in or pursuant to Section 3(b) hereof, for new Warrants, in substantially the form of this Warrant evidencing, in the aggregate, the right to purchase the number of Warrant Shares which may then be purchased hereunder, each of such new Warrants to be dated the date of such exchange and to represent the right to purchase such number of Warrant Shares as shall be designated by the Registered Holder at the time of such surrender.

Section 3.                                            Duration and Exercise of this Warrant.

(a)                                  This Warrant shall be exercisable by the Registered Holder as to the Warrant Shares at any time during the period commencing on the Exercise Date and ending on the Expiration Date. At 5:00 p.m., Texas time, on the Expiration Date, this Warrant, to the extent not previously exercised, shall become void and of no further force or effect.  Subject to Sections 4, and 7 hereof, upon exercise or surrender of this Warrant, with the Form of Election to Purchase attached hereto completed and duly endorsed by the Registered Holder, to the Company at 10375 Richmond, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention:  ▇▇▇▇▇ ▇▇▇▇▇, or at such other address as the Company may specify in writing to the Registered Holder, and upon payment of the Exercise Price multiplied by up to the number of Warrant Shares then issuable upon exercise of this Warrant in lawful money of the United States of America, all as specified by the Registered Holder in the Form of Election to Purchase, the Company shall promptly issue and cause to be delivered to or upon the written order of the Registered Holder, and in such name or names as the Registered Holder may designate, a certificate for the Warrant Shares issued upon such exercise.  Any person so designated in the Form of Election to Purchase, duly endorsed by the Registered Holder, as the person to be named on the certificates for the Warrant Shares, shall be deemed to have become holder of record of such Warrant Shares, evidenced by such certificates, as of the Date of Exercise (as hereinafter defined) of such Warrant.

(b)                                 The Registered Holder may pay the applicable Exercise Price pursuant to Section 3(b), at the option of the Registered Holder, either (i) in cash or by cashier’s or certified bank check payable to the Company, (ii) by wire transfer of immediately available funds to the account which shall be indicated in writing by the Company to the Registered Holder, (iii) by net issue election as provided below, or (iv) by any combination of items (i), (ii) and (iii), in any case, in an amount equal to the product of the Exercise Price multiplied by the number of Warrant Shares being purchased upon such exercise (the “Aggregate Exercise Price”).

(c)                                  The “Date of Exercise” of any Warrant means the date on which the Company shall have received (i) this Warrant, with the Form of Election to Purchase attached hereto appropriately completed and duly endorsed, and (ii) payment of the Aggregate Exercise Price as provided herein.

(d)                                 The Registered Holder may elect to receive, without payment by the Registered Holder of any additional consideration, shares of Common Stock equal to the value of the Common Stock or any portion thereof by the surrender of a duly completed Net Issue Election Notice, in the form attached hereto, at the office of the Company.  Thereupon, the Company shall issue to the Registered

2

Holder such number of fully paid and nonassessable shares of Common Stock as is computed using the following formula:

(e)                                  For purposes of this Section 3, fair market value of a share of Common Stock at the time that the net issue election is made shall mean:

(i)                                     if traded on a stock exchange, the fair market value of the Common Stock shall be deemed to be the average of the closing selling prices of the Common Stock on the stock exchange determined by the Board of Directors of the Company to be the primary market for the Common Stock over the ten (10) trading day period ending on the date prior to the date that the net issue election is made, as such prices are officially quoted in the composite tape of transactions on such exchange;

(ii)                                  if traded over-the-counter, the fair market value of the Common Stock shall be deemed to be the average of the closing bid prices (or, if such information is available, the closing selling prices) of the Common Stock over the ten (10) trading day period ending on the date prior to the date that the net issue election is made, as such prices are reported by The OTC Bulletin Board, any successor system or any exchange on which it is listed, whichever is applicable; or

(iii)                               if, at the time of exercise, there is no public market for the Common Stock, then the fair market value shall be determined by the Board of Directors of the Company in good faith.

(f)                                    This Warrant shall not be exercisable until the Exercise Date (the “Exercise Restriction Period”).  Subject to the Exercise Restriction Period, this Warrant shall be exercisable either in its entirety or, from time to time, for part only of the number of Warrant Shares which are issuable hereunder.  If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of the certificates for the Warrant Shares issued pursuant to such exercise, deliver to the Registered Holder a new Warrant evidencing the rights to purchase the remaining Warrant Shares, which Warrant shall be substantially in the form of this Warrant.

Section 4.                                            Payment of Taxes and Expenses.

3

(a)                                  The Company will pay all expenses and taxes (other than any federal or state income tax or similar obligations of the Registered Holder) and other governmental charges attributable to the preparation, execution, issuance and delivery of this Warrant, any new Warrant and the Warrant Shares; provided, however, that the Company shall not be required to pay any tax in respect of the transfer of this Warrant or the Warrant Shares, or the issuance or delivery of certificates for Warrant Shares upon the exercise of this Warrant, to a person or entity other than a Registered Holder or an Affiliate (as hereinafter defined) of such Registered Holder.

(b)                                 An “Affiliate” of any person or entity means any other person or entity directly or indirectly controlling, controlled by or under direct or indirect common control with such person or entity.

Section 5.                                            Mutilated or Missing Warrant Certificate.  If this Warrant shall be mutilated, lost, stolen or destroyed, upon request by the Registered Holder, the Company will issue, in exchange for and upon cancellation of the mutilated Warrant, or in substitution for the lost, stolen or destroyed Warrant, a substitute Warrant, in substantially the form of this Warrant, of like tenor, but, in the case of loss, theft or destruction, only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of this Warrant and, if requested by the Company, indemnity also reasonably satisfactory to it.

Section 6.                                            Reservation, Listing and Issuance of Warrant Shares.

(a)                                  The Company will at all times have authorized, and reserve and keep available, free from preemptive rights, for the purpose of enabling it to satisfy any obligation to issue Warrant Shares upon the exercise of the rights represented by this Warrant, the number of Warrant Shares deliverable upon exercise of this Warrant.  The Company will, at its expense, use it best efforts to cause such shares to be included in or listed on (subject to issuance or notice of issuance of Warrant Shares) all markets or stock exchanges in or on which the Common Stock is included or listed not later than the date on which the Common Stock is first included or listed on any such market or exchange and will thereafter maintain such inclusion or listing of all shares of Common Stock from time to time issuable upon exercise of this Warrant.

(b)                                 Before taking any action which could cause an adjustment pursuant to Section 7 hereof reducing the Exercise Price below the par value of the Warrant Shares, the Company will take any corporate action which may be necessary in order that the Company may validly and legally issue at the Exercise Price, as so adjusted, Warrant Shares that are fully paid and non-assessable.

(c)                                  The Company covenants that all Warrant Shares will, upon issuance in accordance with the terms of this Warrant, be (i) duly authorized, fully paid and nonassessable, and (ii) free from all taxes with respect to the issuance thereof and from all liens, charges and security interests.

Section 7.                                            Adjustment of Number of Warrant Shares.

(a)                                  The number of Warrant Shares to be purchased upon exercise hereof is subject to change or adjustment from time to time as hereinafter provided:

(i)                                     Stock Dividends; Stock Splits; Reverse Stock Splits; Reclassifications.  In case the Company shall (a) pay a dividend with respect to its Common Stock in shares of capital stock, (b) subdivide its outstanding shares

4

of Common Stock, (c) combine its outstanding shares of Common Stock into a smaller number of shares of any class of Common Stock or (d) issue any shares of its capital stock in a reclassification of the Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), other than elimination of par value, a change in par value, or a change from par value to no par value (any one of which actions is herein referred to as an “Adjustment Event”), the number of Warrant Shares  purchasable upon exercise of the Warrant immediately prior to the record date for such Adjustment Event shall be adjusted so that the Registered Holder shall thereafter be entitled to receive the number of shares of Common Stock or other securities of the Company (such other securities thereafter enjoying the rights of shares of Common Stock under this Warrant) that such Registered Holder would have owned or have been entitled to receive after the happening of such Adjustment Event, had such Warrant been exercised immediately prior to the happening of such Adjustment Event or any record date with respect thereto.  An adjustment made pursuant to this Section 7(a)(i) shall become effective immediately after the effective date of such Adjustment Event retroactive to the record date, if any, for such Adjustment Event.

(ii)                                  Adjustment of Exercise Price.  Whenever the number of Warrant Shares purchasable upon the exercise of each Warrant is adjusted pursuant to Section 7(a)(i), the Exercise Price for each Warrant Share payable upon exercise of each Warrant shall be adjusted by multiplying such Exercise Price immediately prior to such adjustment by a fraction, the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of each Warrant immediately prior to such adjustment, and the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

(iii)                               Adjustments for Consolidation, Merger, Sale of Assets, Reorganization, etc..  In case the Company (a) consolidates with or merges into any other corporation and is not the continuing or surviving corporation of such consolidation of merger, or (b) permits any other corporation to consolidate with or merge into the Company and the Company is the continuing or surviving corporation but, in connection with such consolidation or merger, the Common Stock is changed into or exchanged for stock or other securities of any other corporation or cash or any other assets, or (c) transfers all or substantially all of its properties and assets to any other corporation, or (d) effects a capital reorganization or reclassification of the capital stock of the Company in such a way that holders of Common Stock shall be entitled to receive stock, securities, cash and/or assets with respect to or in exchange for Common Stock, then, and in each such case, proper provision shall be made so that, upon the basis and upon the terms and in the manner provided in this subsection 7(a)(iii), the Registered Holder, upon the exercise of this Warrant at any time after the consummation of such consolidation, merger, transfer, reorganization or reclassification, shall be entitled to receive (at the aggregate Exercise Price in effect for all shares of Common Stock issuable upon such exercise immediately prior to such consummation as adjusted to the time of such transaction), in lieu of shares of Common Stock issuable upon such exercise prior to such consummation, the stock and other securities, cash and/or assets to which such holder would have been entitled upon such consummation if the Registered Holder had so exercised this Warrant immediately prior thereto (subject to adjustments subsequent to such corporate action as nearly equivalent as possible to the adjustments provided for in this Section).

(iv)                              De Minimis Adjustments.  No adjustment in the Exercise Price and number of Warrant Shares purchasable hereunder shall be required unless such adjustment would require

5

an increase or decrease of at least $0.02 in the Exercise Price; provided, however, that any adjustments which by reason of this Section 7(a)(iv) are not required to be made shall be carried forward and taken into account in any subsequent adjustment.  All calculations shall be made to the nearest full share.

(b)                                 Notice of Adjustment.  Whenever the number of Warrant Shares purchasable upon the exercise of each Warrant or the Exercise Price is adjusted, as herein provided, the Company shall promptly notify the Registered Holder in writing (such writing referred to as an “Adjustment Notice”) of such adjustment or adjustments and shall deliver to such Registered Holder a statement setting forth the number of shares of Common Stock purchasable upon the exercise of each Warrant and the Exercise Price after such adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was made.

(c)                                  Other Notices.  In case at any time:

(i)                                     the Company shall declare any cash dividend on its Common Stock;

(ii)                                  the Company shall pay any dividend payable in stock upon its Common Stock or make any distribution (other than regular cash dividends) to the holders of its Common Stock;

(iii)                               the Company shall offer for subscription pro rata to all of the holders of its Common Stock any additional shares of stock of any class or other rights;

(iv)                              the Company shall authorize the distribution to all holders of its Common Stock of evidences of its indebtedness or assets (other than cash dividends or cash distributions payable out of earnings or earned surplus or dividends payable in Common Stock);

(v)                                 there shall be any capital reorganization, or reclassification of the capital stock of the Company, or consolidation or merger of the Company with another corporation (other than a subsidiary of the Company in which the Company is the surviving or continuing corporation and no change occurs in the Company’s Common Stock), or sale of all or substantially all of its assets to another corporation; or

(vi)                              there shall be a voluntary or involuntary dissolution, liquidation, bankruptcy, assignment for the benefit of creditors, or winding up of the Company;

then, in any one or more of said cases the Company shall give written notice, addressed to the Registered Holder at the address of such Registered Holder as shown on the books of the Company, of (1) the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution or subscription rights, or (2) the date (or, if not then known, a reasonable approximation thereof by the Company) on which such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, bankruptcy, assignment for the benefit of creditors, winding up or other action, as the case may be, shall take place.  Such notice shall also specify (or, if not then known, reasonably approximate) the date as of which the holders of Common Stock of record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, bankruptcy, assignment for the benefit of creditors, winding up, or other action, as the case may be.  Such written notice shall be given (except as to any bankruptcy proceeding) at least

6

five (5) business days prior to the action in question and not less than five (5) business days prior to the record date or the date on which the Company’s transfer books are closed in respect thereto.  Such notice shall also state that the action in question or the record date is subject to the effectiveness of a registration statement under the 1933 Act, or to a favorable vote of stockholders, if either is required.

(d)                                 Statement on Warrants.  The form of this Warrant need not be changed because of any change in the Exercise Price or in the number or kind of shares purchasable upon the exercise of a Warrant.  However, the Company may at any time in its sole discretion make any change in the form of the Warrant that it may deem appropriate and that does not affect the substance thereof and any Warrant thereafter issued, whether in exchange or substitution for any outstanding Warrant or otherwise, may be in the form so changed.

(e)                                  Fractional Interest.  The Company shall not be required to issue fractional Warrant Shares on the exercise of the Warrants.  The number of full Warrant Shares which shall be issuable upon such exercise shall be computed on the basis of the aggregate number of whole shares of Common Stock purchasable on the exercise of the Warrants so presented.  If any fraction of a share of Common Stock would, except for the provisions of this Section 7(e) be issuable on the exercise of the Warrants (or specified proportion thereof), the Company shall pay an amount in cash calculated by it to be equal to the then fair value of one share of Common Stock, as determined by the Board of Directors of the Company in good faith, multiplied by such fraction computed to the nearest whole cent.

Section 8.                                            No Rights or Liabilities as a Stockholder.  The Registered Holder shall not be entitled to vote or be deemed the holder of Common Stock or any other securities of the Company which may at any time be issuable on the exercise hereof, nor shall anything contained herein be construed to confer upon the holder of this Warrant, as such, the rights of a stockholder of the Company or the right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or give or withhold consent to any corporate action or to receive notice of meetings or other actions affecting stockholders (except as provided herein), or to receive dividends or subscription rights or otherwise, until the Date of Exercise shall have occurred.  No provision of this Warrant, in the absence of affirmative action by the Registered Holder hereof to purchase shares of Common Stock, and no mere enumeration herein of the rights and privileges of the Registered Holder, shall give rise to any liability of such holder for the Exercise Price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

Section 9.                                            Transfer Restrictions; Registration of the Warrant and Warrant Shares.

(a)                                  Neither the Warrant nor the Warrant Shares have been registered under the 1933 Act.  The Registered Holder, by acceptance hereof, represents that it is acquiring this Warrant to be issued to it for its own account and not with a view to the distribution thereof, and agrees not to sell, transfer, pledge or hypothecate this Warrant, any purchase rights evidenced hereby or any Warrant Shares unless a registration statement is effective for this Warrant or the Warrant Shares under the 1933 Act, or in the opinion of such Registered Holder’s counsel reasonably satisfactory to the Company, a copy of which opinion shall be delivered to the Company, such registration is not required as some other exemption from the registration requirement of the 1933 Act and applicable laws is available.

(b)                                 Subject to the provisions of the following paragraph of this Section 9, each Certificate for Warrant Shares shall be stamped or otherwise imprinted with a legend in substantially the following form:

7

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED (EXCEPT IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THESE SECURITIES) OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER AND, IN THE CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT OR THE ISSUER HAS RECEIVED DOCUMENTATION REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER SUCH ACT.

(c)                                  The restrictions and requirements set forth in the foregoing paragraph shall apply with respect to Warrant Shares unless and until such Warrant Shares are sold or otherwise transferred pursuant to an effective registration statement under the 1933 Act or are otherwise no longer subject to the restrictions of the 1933 Act, at which time the Company agrees to promptly cause such restrictive legends to be removed and stop transfer restrictions applicable to such Warrant Shares to be rescinded.

(d)                                 The Company will use its best efforts to comply with the reporting requirements of Section 13 and 15(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”) (whether or not it shall be required to do so pursuant to such Sections) and will use its best efforts to comply with all other public information reporting requirements of the Securities and Exchange Commission (“SEC”) including, without limitation, Rule 144 promulgated under the ▇▇▇▇ ▇▇▇) from time to time in effect and relating to the availability of an exemption from the 1933 Act for sale of restricted securities.  The Company also will cooperate with the Registered Holder and with each holder of any Warrant Shares in supplying such information as may be necessary for any such holders to complete and file any information reporting forms presently or hereafter required by the SEC as a condition to the availability of an exemption from the 1933 Act for the sale of restricted securities.

Section 10.                                      Registration Rights.  The Holder shall have and be entitled to exercise the rights of registration granted under the Registration Rights Agreement filed pursuant to the Purchase Agreement between the Company and PERM Energy Advisors, Inc.

Section 11.                                      Notices.  All notices, requests, demands and other communications relating to this Warrant shall be in writing and shall be deemed to have been duly given if delivered personally or sent by United States certified or registered first-class mail, postage prepaid, return receipt requested, to the parties hereto at the following addresses or at such other address as any party hereto shall hereafter specify by notice to the other party hereto:

(a)                                  If to the Registered Holder of this Warrant or the holder of the Warrant Shares, addressed to the address of such Registered Holder or holder as set forth on books of the Company or otherwise furnished by the Registered Holder or holder to the Company.

(b)                                 If to the Company, addressed to:

8

Binding Effect.  This Warrant shall be binding upon and inure to the sole and exclusive benefit of the Company, its successors and assigns, and the holder or holders from time to time of this Warrant and the Warrant Shares.

Section 12.                                      Survival of Rights and Duties.  This Warrant shall terminate and be of no further force and effect on the earlier of (i) 5:00 p.m., Texas time, on the Expiration Date and (ii) the date on which this Warrant and all purchase rights evidenced hereby have been exercised, except that the provisions of Sections 4, 6(c), 10 and 11 hereof shall continue in full force and effect after such termination date.

Section 13.                                      Governing Law.  This Warrant shall be construed in accordance with and governed by the laws of the State of Texas.

Section 14.                                      Holidays.  If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday or a Sunday or shall be a holiday on which The OTC Bulletin Board (or any successor system or exchange on which Common Stock is subsequently listed) is closed, then such action may be taken or such right may be exercised on the next succeeding business day.
