WARRANT

Warrant No. ________

Date of Original Issuance: ____________, 2007

Powder River Basin Gas Corp., a Colorado corporation (the “Company”), hereby certifies that, for value received, _____________________________ or his, her, or its registered assigns (the “Holder”), is entitled to purchase from the Company up to a total of ________________ (_________) shares of common stock, par value $0.001 per share (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price equal to $0.25 per share (as adjusted from time to time as provided in Section 9, the “Exercise Price”), at any time and from time to time from and after the date hereof and through and including _____________, 2012 (the “Expiration Date”), and subject to the following terms and conditions:

Definitions.

This warrant (the “Warrant”) is one of a series of similar warrants issued pursuant to the Investment Banking Agreement, between the Company and Sunrise Securities Corp., dated as of October ___, 2007, as amended (the “Investment Banking Agreement”). All such warrants are collectively referred to herein as the “Warrants”. Capitalized terms used and not otherwise defined herein have the meanings as defined in the Investment Banking Agreement.

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

Registration of Transfers. The Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached hereto duly completed and signed, to the Company at its address specified herein. Upon any such registration or transfer, a new Warrant to purchase Common Stock, in substantially the form of this Warrant (any such new Warrant, a “New Warrant”), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

Exercise and Duration of Warrants.

(a)

This Warrant shall be exercisable by the registered Holder at any time and from time to time on or after the date hereof up to and including the Expiration Date. The Company may not call or redeem all or any portion of this Warrant without the prior written consent of the Holder.

(b)

A Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached hereto (the “Exercise Notice”), and (ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised (which may take the form of a “cashless exercise” if so indicated in the Exercise Notice), and the date such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is the “Date of Exercise.”

Delivery of Warrant Shares.

(a)

Upon exercise of this Warrant, the Company shall promptly (but in no event later than three (3) trading days after the Date of Exercise issue and deliver to the Holder, a certificate for the Warrant Shares issuable upon such exercise. The Company shall, upon request of the Holder and subsequent to the date on which a registration statement covering the resale of the Warrant Shares has been declared effective by the Securities and Exchange Commission, use its best efforts to deliver Warrant Shares hereunder electronically through the Depository Trust Corporation or another established clearing corporation performing similar functions, if available, provided, that, the Company may, but will not be required to change its transfer agent if its current transfer agent cannot deliver Warrant Shares electronically through the Depository Trust Corporation.

(b)

This Warrant is exercisable, either in its entirety or, from time to time, for a portion of the number of Warrant Shares. Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares. Notwithstanding the foregoing, should the Holder hereof physically surrender this Warrant in connection with a partial exercise of this Warrant (or, in the event that this Warrant has been lost, mutilated or stolen, an affidavit of loss in respect thereof in form and substance reasonably satisfactory to the Company), the Company shall promptly issue (or cause to be issued) and delivered to the Holder, at its expense, a New Warrant evidencing the right to purchase the remaining number of Warrant Shares, if any, following such exercise.

(c)

The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity (which shall not include a surety bond), if requested. Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the New Warrant.

Reservation of Warrant Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, shall be duly and validly authorized, issued and fully paid and nonassessable.

Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 9.

(a)

Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 9(a) occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event.

(b)

Fundamental Transactions. If, at any time while this Warrant is outstanding, (1) the Company effects any merger or consolidation of the Company with or into another Person, (2) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (3) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property, or (4) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “Alternate Consideration”). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. At the Holder’s option and request, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant substantially in the form of this Warrant and consistent with the foregoing provisions and evidencing the Holder’s right to purchase the Alternate Consideration for the aggregate Exercise Price upon exercise thereof. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 9(b) and insuring that the Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(c)

In case the Company shall issue shares of Common Stock or rights, options, warrants or other securities to subscribe for or purchase Common Stock, or securities convertible or exercisable into or exchangeable for Common Stock (“Common Stock Equivalents”) (excluding shares, rights, options, warrants, or convertible or exchangeable securities, issued or issuable (i) in any of the transactions with respect to which an adjustment of the Exercise Price is provided pursuant to Sections 9(a) or 9(b) above, (ii) upon exercise of the Warrants, and (iii) to directors and employees (including officers) pursuant to stock option and incentive plans existing as of the date hereof, at a price per share lower than the Base Price (as hereinafter defined) per share of Common Stock in effect immediately prior to such issuance, then the Exercise Price shall be reduced on the date of such issuance to a price (calculated to the nearest cent) determined by multiplying the Exercise Price in effect immediately prior to such issuance by a fraction, (1) the numerator of which shall be an amount equal to the sum of (A) the number of shares of Common Stock outstanding immediately prior to such issuance plus (B) the quotient obtained by dividing the consideration received by the Company upon such issuance by the Base Price, and (2) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such issuance. For the purposes of such adjustments, the maximum number of shares which the holders of any such Common Stock Equivalents, shall be entitled to subscribe for or purchase or convert or exchange such securities into shall be deemed to be issued and outstanding as of the date of such issuance (whether or not such Common Stock Equivalent is then exercisable, convertible or exchangeable), and the consideration received by the Company therefor shall be deemed to be the consideration received by the Company for such Common Stock Equivalents, plus the minimum aggregate consideration or premiums stated in such Common Stock Equivalents, to be paid for the shares covered thereby. No further adjustment of the Exercise Price shall be made as a result of the actual issuance of shares of Common Stock on exercise of such Common Stock Equivalents. On the expiration or the termination of such Common Stock Equivalents, or the termination of such right to convert or exchange, the Exercise Price shall forthwith be readjusted (but only with respect to that portion of the Warrants which has not yet been exercised) to such Exercise Price as would have obtained had the adjustments made upon the issuance of such Common Stock Equivalents, been made upon the basis of the delivery of only the number of shares of Common Stock actually delivered upon the exercise of such Common Stock Equivalents; and on any change of the number of shares of Common Stock deliverable upon the exercise of any such Common Stock Equivalents, or any change in the consideration to be received by the Company upon such exercise, conversion, or exchange, including, but not limited to, a change resulting from the anti-dilution provisions thereof, the Exercise Price, as then in effect, shall forthwith be readjusted (but only with respect to that portion of the Warrants which has not yet been exercised or converted after such change) to such Exercise Price as would have been obtained had an adjustment been made upon the issuance of such Common Stock Equivalents not exercised prior to such change, or securities not converted or exchanged prior to such change, on the basis of such change. In case the Company shall issue shares of Common Stock or any such Common Stock Equivalents, for a consideration consisting, in whole or in part, of property other than cash or its equivalent, then the “price per share” and the “consideration received by the Company” for purposes of the first sentence of this Section 9(c) shall be as determined in good faith by the Board of Directors of the Company. Shares of Common Stock owned by or held for the account of the Company or any majority-owned subsidiary shall not be deemed outstanding for the purpose of any such computation. For the purposes of this Agreement “Base Price” shall mean the greater of $0.25 (as adjusted for any stock dividends, combinations, splits, recapitalizations and the like) and the then Common Stock Market Price (as defined).

(d)

Pro Rata Distributions. If the Company, at any time while this Warrant is outstanding, distributes to holders of Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by Section 9(a)), (iii) rights or warrants to subscribe for or purchase any security (other than Common Stock Equivalents which are covered by Section 9(c)), or (iv) any other asset (in each case, “Distributed Property”), then in each such case the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution shall be adjusted (effective on such record date) to equal the product of such Exercise Price times a fraction of which the denominator shall be the average of the Closing Prices (as defined below) for the five trading days immediately prior to (but not including) such record date and of which the numerator shall be such average less the then fair market value of the Distributed Property distributed in respect of one outstanding share of Common Stock, as determined by the Company's independent certified public accountants that regularly examine the financial statements of the Company (an “Appraiser”). In such event, the Holder, after receipt of the determination by the Appraiser, shall have the right to select an additional appraiser (which shall be a nationally recognized accounting firm), in which case such fair market value shall be deemed to equal the average of the values determined by each of the Appraiser and such additional appraiser. As an alternative to the foregoing adjustment to the Exercise Price, at the request of the Holder delivered before the 90th day after such record date, the Company will deliver to such Holder, within five trading days after such request (or, if later, on the effective date of such distribution), the Distributed Property that such Holder would have been entitled to receive in respect of the Warrant Shares for which this Warrant could have been exercised immediately prior to such record date. If a Holder has elected to receive Distributed Property and such Distributed Property is not delivered to a Holder pursuant to the preceding sentence, then upon expiration of or any exercise of the Warrant that occurs after such record date, such Holder shall remain entitled to receive, in addition to the Warrant Shares otherwise issuable upon such exercise (if applicable), such Distributed Property.

(e)

Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to Sections 9(a), 9(c) or 9(d), the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

(f)

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

(g)

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

(h)

Notices of Corporate Events. If the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes a repurchase of Common Stock or the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction, at least 10 business days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to insure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to participate in or vote with respect to such transaction.

(i)

Successive Adjustments and Changes. The provisions of Section 9 shall similarly apply to successive dividends, subdivisions, combinations, and distributions, to successive consolidations, mergers, sales, leases, or conveyances, and to successive reclassifications, changes of shares of Common Stock and issuances of Common Stock, warrants, options or other rights to subscribe for or purchase Common Stock, or securities convertible into Common Stock. If applicable, appropriate adjustment, as determined in good faith by the Company’s Board of Directors, shall be made in the application of the provisions herein set forth with respect to the rights and interests of the Holder so that the provisions of Section 9 shall thereafter be applicable, as nearly as possible, in relation to any shares or other property thereafter deliverable upon exercise of this Warrant.

10.

Payment of Exercise Price. The Holder may pay the Exercise Price by delivery of a check made payable to the Company or by wire transfer to an account designated in writing by the Company or, if the Holder so elects, the Holder may satisfy its obligation to pay the Exercise Price through a “cashless exercise,” in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:


	X = Y*((A-B)/A)
where:
	X = the number of Warrant Shares to be issued to the Holder.

	Y = the number of Warrant Shares with respect to which this Warrant is being exercised.

	A = the Common Stock Market Price.

	B = the Exercise Price.

The Holder may satisfy its obligation to pay the Exercise Price through a “cashless exercise” of the Warrant Shares (such portion of the Warrant Shares, the “Cashless Exercise Warrant Shares”). If, at any time there shall be an adjustment to the number of Warrant Shares pursuant to Section 9 hereof, the number of Cashless Exercise Warrant Shares shall be deemed automatically and proportionately adjusted to reflect such change in the number of Warrant Shares.

As used herein, the term “Common Stock Market Price” means the greater of: (i) the Closing Price of the trading day immediately preceding (but not including) the Date of Exercise, (ii) the average of the Closing Prices for the 10 trading days immediately preceding (but not including) the Date of Exercise, and (iii) if applicable, the average of the Closing Prices for the 90 trading days immediately following the date on which a Registration Statement covering the resale of the Warrant Shares is declared effective (or, if the Date of Exercise is less than 90 trading days following such effective date, then such shorter period). For purposes of Rule 144 promulgated under the Securities Act and to the extent permitted by applicable law, 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. As used herein, the term “Closing Price” means, for any date, the price determined by the first of the following clauses that applies: (A) if the Common Stock is then listed or quoted on New York Stock Exchange, the American Stock Exchange, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market or the OTC Bulletin Board or any successor to any of the foregoing, the closing price per share of the Common Stock for such date (or the nearest preceding date) on the primary market or exchange on which the Common Stock is then listed or quoted; (B) if prices for the Common Stock are then reported in the “Pink Sheets” published by the National Quotation Bureau Incorporated (or a similar organization or agency succeeding to its functions of reporting prices), the most recent closing bid price per share of the Common Stock so reported; or (C) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Investors and the Company; provided, that, the fair market value shall not be less than $0.25.

11.

Limitations on Exercise.

(a)

Notwithstanding anything to the contrary contained herein, at any time that any of the Company’s equity securities are registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the number of shares of Common Stock that may be acquired by the Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Holder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder's for purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% (the “5% Maximum Percentage”) of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The Company shall, instead of issuing shares of Common Stock in excess of the limitation referred to in this Section 11(a), suspend its obligation to issue shares in excess of the foregoing limitation until such time, if any, as such shares of Common Stock may be issued in compliance with such limitation. Additionally, by written notice to the Company, the Holder may waive the provisions of this Section 11(a) or increase or decrease the 5% Maximum Percentage to any other percentage specified in such notice; provided, that (i) any such waiver or increase or decrease will not be effective until the 61^st day after such notice is delivered to the Company, and (ii) any such waiver or increase or decrease will apply only to the Holder and not to any other holder of Warrants.

(b)

Notwithstanding anything to the contrary contained herein and regardless of whether the restrictions contained in Section 11(a) are waived as provided therein, the number of shares of Common Stock that may be acquired by the Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Holder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder's for purposes of Section 13(d) of the Exchange Act, does not exceed 9.999% (the “10% Maximum Percentage”) of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The Company shall, instead of issuing shares of Common Stock in excess of the limitation referred to in this Section 11(b), suspend its obligation to issue shares in excess of the foregoing limitation until such time, if any, as such shares of Common Stock may be issued in compliance with such limitation. The provisions of this Section 11(b) may not be waived.

(c)

This Section 11 shall not restrict the number of shares of Common Stock which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder may receive in the event of a Fundamental Transaction as contemplated in Section 9(b) this Warrant or the amount of Distributed Property to which the Holder may become entitled pursuant to Section 9(d) of this Warrant. In addition, this provision shall not in any way limit any other adjustment to be made pursuant to Section 9 hereof.

12.

Registration Rights.

(a)

Definition of Registrable Securities; Majority. As used herein, the term “Registrable Securities” means the Warrant Shares until the date on which all of the Warrant Shares have been sold and reissued free of a restrictive legend or the date on which all of the Warrant Shares may be sold without volume restrictions pursuant to Rule 144(k) promulgated under the Securities Act. For purposes of this Warrant, the term “Majority”, in reference to the holders of Registrable Securities, shall mean in excess of fifty percent (50%) of the then outstanding Registrable Securities (assuming the exercise of all Warrants).

(b)

Demand Registration. The Holder shall have no demand registration rights.

(c)

Piggyback Registration. If the Company proposes to register under the Securities Act any of its securities (other than on Form S-8 or Form S-4 or their then equivalents and other than shares to be issued solely (i) in connection with any acquisition of any entity or business, (ii) upon the exercise of stock options, or (iii) pursuant to employee benefit plans), it shall send to each holder of Registrable Securities, including each holder who has the right to acquire Registrable Securities, written notice of such determination and, if within fifteen (15) days after receipt of such notice, such holder shall so request in writing, the Company shall use its reasonable best efforts to include in such registration statement all or any part of the Registrable Securities such holder requests to be registered therein; provided that, if, in connection with any offering involving an underwriting of Common Stock to be issued by the Company, the managing underwriter shall inform the Company of its belief that inclusion in such distribution of all or a specified number of such securities proposed to be distributed by such underwriters would interfere with the successful marketing of the securities being distributed by such underwriters and shall impose a limitation on the number of shares of such Common Stock which may be included in any such registration statement because, in its judgment, such limitation is necessary to effect an orderly public distribution, and such limitation is imposed pro rata with respect to all securities whose holders have a contractual, incidental right to include such securities in the registration statement and as to which inclusion has been requested pursuant to such right and there is first excluded from such registration statement all shares of Common Stock sought to be included therein by (i) any holder thereof not having any such contractual, incidental registration rights, and (ii) any holder thereof (other than the holders of Registrable Securities) having contractual, incidental registration rights, the Company shall then be obligated to include in such registration statement only such limited portion (which may be none) of the Registrable Securities with respect to which such holder has requested inclusion hereunder.

(d)

Registration Procedures. Whenever the holders of Registrable Securities have properly requested that any Registrable Securities be registered pursuant to the terms of this Warrant, the Company shall use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible:

(i)

prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its reasonable best efforts to cause such registration statement to become effective;

(ii)

notify such holders of the effectiveness of each registration statement filed hereunder and prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to (i) keep such registration statement effective and the prospectus included therein usable for a period commencing on the date that such registration statement is initially declared effective by the SEC and ending on the date when all Registrable Securities covered by such registration statement have been sold pursuant to the registration statement or cease to be Registrable Securities, and (ii) comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement;

(iii)

furnish to such holders such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such holders;

(iv)

use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as such holders reasonably request and do any and all other acts and things which may be reasonably necessary or advisable to enable such holders to consummate the disposition in such jurisdictions of the Registrable Securities owned by such holders; provided, however, that the Company shall not be required to: (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph; (ii) subject itself to taxation in any such jurisdiction; or (iii) consent to general service of process in any such jurisdiction;

(v)

notify such holders, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein, in light of the circumstances in which they are made, not materially misleading, and, at the reasonable request of such holders, the Company shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances in which they are made, not materially misleading;

(vi)

provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement;

(vii)

make available for inspection by any underwriter participating in any disposition pursuant to such registration statement, and any attorney, accountant or other agent retained by any such underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, managers, employees and independent accountants to supply all information reasonably requested by any such underwriter, attorney, accountant or agent in connection with such registration statement;

(viii)

otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement of the Company, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and, at the option of the Company, Rule 158 thereunder;

(ix)

in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Registrable Securities included in such registration statement for sale in any jurisdiction, the Company shall use its reasonable best efforts promptly to obtain the withdrawal of such order;

(x)

use its reasonable best efforts to cause any Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities; and

(xi)

if the offering is underwritten, use its reasonable best efforts to furnish on the date that Registrable Securities are delivered to the underwriters for sale pursuant to such registration, an opinion dated such date of counsel representing the Company for the purposes of such registration, addressed to the underwriters covering such issues as are reasonably required by such underwriters.

(e)
